An Electron-Ion Collider (EIC) has been proposed to further explore the strong force and QCD, focusing on the structure and the interaction of gluon-dominated matter. A generic detector R&D program (EIC PID consortium) for the particle identification in EIC experiments was formed to explore technologically advanced solutions in this scope. In this context two Ring Imaging Cherenkov (RICH) counters have been proposed: a modular RICH detector which consists of an aerogel radiator, a Fresnel lens, a mirrored box, and pixelated photon sensor; a dual-radiator RICH, consisting of an aerogel radiator and C2F6 gas in a mirror-focused configuration. We present the simulations of the two detectors and their estimated performance.

The COMPASS experiment at CERN uses a secondary pion beam from the Super Proton Synchrotron (SPS) at CERN to explore the spin structure of nucleons. A new drift chamber, DC5, will be integrated into the COMPASS spectrometer to replace an aging straw tube detector. DC5 will detect muon pairs from Drell-Yan scattering of a pion-beam off a transversely polarized proton target. This data will be used to determine the correlation between transverse proton spin and the intrinsic transverse momentum of up-quarks inside the proton, the Sivers effect. DC5 is a large area planar drift chamber with 8 layers of anode-frames made of G10 fiberglass-epoxy. The G10 frames support printed circuit boards for soldering 20 μm diameter anode and 100 μm diameter field wires. The anode planes are sandwiched by 13 graphite coated Mylar cathode planes. To ensure a well-functioning of DC5, the wires were carefully tested. An optical inspection and a spectral analysis was performed with an Environmental Scanning Electron Microscope (ESEM) to verify the composition and dimensions and the integrity of the gold plating on the surface of these wires. The spectra of the wires were studied at 10 and 30 keV.

2017-12-01

The LHCb RICH system provides hadron identification over a wide momentum range (2-100 GeV/c). This detector system is key to LHCb's precision flavour physics programme, which has unique sensitivity to physics beyond the standard model. This paper reports on the performance of the LHCb RICH in Run II, following significant changes in the detector and operating conditions. The changes include the refurbishment of significant number of photon detectors, assembled using new vacuum technologies, and the removal of the aerogel radiator. The start of Run II of the LHC saw the beam energy increase to 6.5 TeV per beam and a new trigger strategy for LHCb with full online detector calibration. The RICH information has also been made available for all trigger streams in the High Level Trigger for the first time.

The High Acceptance Di-Electron Spectrometer (HADES) is operational since the year 2000 and uses a hadron blind RICH detector for electron identification. The RICH photon detector is currently replaced by Hamamatsu H12700 MAPMTs with a readout system based on the DiRICH front-end module. The electronic readout chain is being developed as a joint effort of the HADES-, CBM- and PANDA collaborations and will also be used in the photon detectors for the upcoming Compressed Baryonic Matter (CBM) and PANDA experiments at FAIR . This article gives a brief overview on the photomultipliers and their quality assurance test measurements, as well as first measurements of the new DiRICH front-end module in final configurations.

The future of RICH detectors through the light of the LHCb RICH

NASA Astrophysics Data System (ADS)

D'Ambrosio, C.; LHCb RICH Collaboration

2017-12-01

The limitations in performance of the present RICH system in the LHCb experiment are given by the natural chromatic dispersion of the gaseous Cherenkov radiator, the aberrations of the optical system and the pixel size of the photon detectors. Moreover, the overall PID performance can be affected by high detector occupancy as the pattern recognition becomes more difficult with high particle multiplicities. This paper shows a way to improve performance by systematically addressing each of the previously mentioned limitations. These ideas are applied in the present and future upgrade phases of the LHCb experiment. Although applied to specific circumstances, they are used as a paradigm on what is achievable in the development and realisation of high precision RICH detectors.

The Compressed Baryonic Matter (CBM) experiment at the future Facility for Anti-proton and Ion Research (FAIR) will investigate the phase diagram of strongly interacting matter at high net-baryon density and moderate temperature in A+A collisions. One of the key detectors of CBM to explore this physics program is a Ring Imaging CHerenkov (RICH) detector for electron identification. For a high performance of the RICH detector precise mirror alignment is essential. A three-step correction cycle has been developed, which will be discussed: First a qualitative, fast check of the mirror positions, second a quantitative determination of possible misalignments and third a software correction routine, allowing a proper functioning of the RICH under misalignment conditions.

The CBM RICH detector will use CO2 as radiator gas, focussing glass mirrors with Al+MgF2 reflective and protective coating and Hamamatsu H12700 MAPMTs as photon detectors. The detector will serve for electron to pion separation up to momenta of 8 GeV/c and thus enable in CBM the measurement of electromagnetic radiation from the early and dense fireball in A+A collisions at SIS 100. In this article, the current status of the CBM RICH development will be presented including new measurements of the radiation hardness of the H12700 MAPMT and WLS coatings with p-terphenyl, the new concept for the readout electronics, and optimizations ongoing with respect to the mirror mount structure and overall geometry. Prior to the usage in CBM, part of the already ordered MAPMTs will be used to upgrade the HADES RICH detector for a new measurement campaign at SIS 18 from 2018-2020.

The paper concerns measurements of runaway electrons (REs) which are generated during discharges in tokamaks. The control of REs is an important task in experimental studies within the ITER-physics program. The NCBJ team proposed to study REs by means of Cherenkov-type detectors several years ago. The Cherenkov radiation, induced by REs in appropriate radiators, makes it possible to identify fast electron beams and to determine their spatial- and temporal-characteristics. The results of recent experimental studies of REs, performed in two tokamaks - COMPASS in Prague and FTU in Frascati, are summarized and discussed in this paper. Examples of the electron-induced signals, as recorded at different experimental conditions and scenarios, are presented. Measurements performed with a three-channel Cherenkov-probe in COMPASS showed that the first fast electron peaks can be observed already during the current ramp-up phase. A strong dependence of RE-signals on the radial position of the Cherenkov probe was observed. The most distinct electron peaks were recorded during the plasma disruption. The Cherenkov signals confirmed the appearance of post-disruptive RE beams in circular-plasma discharges with massive Ar-puffing. During experiments at FTU a clear correlation between the Cherenkov detector signals and the rotation of magnetic islands was identified.

The CBM-RICH detector is designed to identify electrons with momenta up to 8 GeV/c and high purity as this is essential for the CBM physics program. The detector consist of a CO2-gaseous radiator, a spherical mirror system, and Multi-Anode PhotoMultiplier Tubes (MAPMT) of type H12700 from Hamamatsu as photon detectors. The detector concept was verified through R&D studies and a laterally scaled prototype. The results were summarized in a TDR, in which open issues were defined concerning the readout electronics, the shielding of the magnetic stray field in the MAPMT region, the radiation hardness of the MAPMT sensors, and the mechanical holding structure of the mirror system. In this article an overview is given on the CBM RICH development with focus on those open issues.

Construction and Gluing of G10 Frames and Printed Circuit Boards to be used in COMPASS Drift Chamber 5

NASA Astrophysics Data System (ADS)

Britto, Vivek

2014-09-01

COMPASS is a fixed-target nuclear physics experiment at CERN which explores the internal structure of the proton. One specific area of research is the measurement of single transverse spin asymmetries in pion beam induced Drell-Yan production of muon pairs from polarized proton targets. The spin dependence of the Drell-Yan cross section may be indicative of contributions from quark orbital angular momentum to the spin of the proton. The University of Illinois at Urbana-Champaign (UIUC), in collaboration with institutes in Taiwan, France, Italy and Germany, is designing and building a new drift chamber, DC5, to replace an aging detector in the COMPASS spectrometer. The frames supporting the anode wires and cathode planes in DC5 are constructed from G10, a fiberglass-epoxy composite. Once the individual sides of each frame have been milled, they are glued together at the corner lap joints. Additionally, printed circuit boards are glued to the anode frames, where sense and field wires will later be soldered. To maintain optimal operation of the drift chamber, the frame thickness after gluing must be within 50 μm of the design value. This presentation will explain the methods employed to achieve the required tolerances for this precision gluing process.

How dim is dim? Precision of the celestial compass in moonlight and sunlight

Prominent in the sky, but not visible to humans, is a pattern of polarized skylight formed around both the Sun and the Moon. Dung beetles are, at present, the only animal group known to use the much dimmer polarization pattern formed around the Moon as a compass cue for maintaining travel direction. However, the Moon is not visible every night and the intensity of the celestial polarization pattern gradually declines as the Moon wanes. Therefore, for nocturnal orientation on all moonlit nights, the absolute sensitivity of the dung beetle's polarization detector may limit the precision of this behaviour. To test this, we studied the straight-line foraging behaviour of the nocturnal ball-rolling dung beetle Scarabaeus satyrus to establish when the Moon is too dim—and the polarization pattern too weak—to provide a reliable cue for orientation. Our results show that celestial orientation is as accurate during crescent Moon as it is during full Moon. Moreover, this orientation accuracy is equal to that measured for diurnal species that orient under the 100 million times brighter polarization pattern formed around the Sun. This indicates that, in nocturnal species, the sensitivity of the optical polarization compass can be greatly increased without any loss of precision. PMID:21282173

Behavioural experiments for magnetoreception in eusocial insects in the last decade are reviewed. Ants and bees use the geomagnetic field to orient and navigate in areas around their nests and along migratory paths. Bees show sensitivity to small changes in magnetic fields in conditioning experiments and when exiting the hive. For the first time, the magnetic properties of the nanoparticles found in eusocial insects, obtained by magnetic techniques and electron microscopy, are reviewed. Different magnetic oxide nanoparticles, ranging from superparamagnetic to multi-domain particles, were observed in all body parts, but greater relative concentrations in the abdomens and antennae of honeybees and ants have focused attention on these segments. Theoretical models for how these specific magnetosensory apparatuses function have been proposed. Neuron-rich ant antennae may be the most amenable to discovering a magnetosensor that will greatly assist research into higher order processing of magnetic information. The ferromagnetic hypothesis is believed to apply to eusocial insects, but interest in a light-sensitive mechanism is growing. The diversity of compass mechanisms in animals suggests that multiple compasses may function in insect orientation and navigation. The search for magnetic compasses will continue even after a magnetosensor is discovered in eusocial insects. PMID:20106876

The purpose of this study was to evaluate quantitatively the patient‐specific 3D dosimetry tool COMPASS with 2D array MatriXX detector for stereotactic volumetric‐modulated arc delivery. Twenty‐five patients CT images and RT structures from different sites (brain, head & neck, thorax, abdomen, and spine) were taken from CyberKnife Multiplan planning system for this study. All these patients underwent radical stereotactic treatment in CyberKnife. For each patient, linac based volumetric‐modulated arc therapy (VMAT) stereotactic plans were generated in Monaco TPS v3.1 using Elekta Beam Modulator MLC. Dose prescription was in the range of 5–20 Gy per fraction. Target prescription and critical organ constraints were tried to match the delivered treatment plans. Each plan quality was analyzed using conformity index (CI), conformity number (CN), gradient Index (GI), target coverage (TC), and dose to 95% of volume (D95). Monaco Monte Carlo (MC)‐calculated treatment plan delivery accuracy was quantitatively evaluated with COMPASS‐calculated (CCA) dose and COMPASS indirectly measured (CME) dose based on dose‐volume histogram metrics. In order to ascertain the potential of COMPASS 3D dosimetry for stereotactic plan delivery, 2D fluence verification was performed with MatriXX using MultiCube phantom. Routine quality assurance of absolute point dose verification was performed to check the overall delivery accuracy. Quantitative analyses of dose delivery verification were compared with pass and fail criteria of 3 mm and 3% distance to agreement and dose differences. Gamma passing rate was compared with 2D fluence verification from MatriXX with MultiCube. Comparison of COMPASS reconstructed dose from measured fluence and COMPASS computed dose has shown a very good agreement with TPS calculated dose. Each plan was evaluated based on dose volume parameters for target volumes such as dose at 95% of volume (D95) and average dose. For critical organs dose at 20% of volume (D20), dose at 50% of volume (D50), and maximum point doses were evaluated. Comparison was carried out using gamma analysis with passing criteria of 3 mm and 3%. Mean deviation of 1.9%±1% was observed for dose at 95% of volume (D95) of target volumes, whereas much less difference was noticed for critical organs. However, significant dose difference was noticed in two cases due to the smaller tumor size. Evaluation of this study revealed that the COMPASS 3D dosimetry is efficient and easy to use for patient‐specific QA of VMAT stereotactic delivery. 3D dosimetric QA with COMPASS provides additional degrees of freedom to check the high‐dose modulated stereotactic delivery with very high precision on patient CT images.

The compass rose pattern in electricity prices.

Batten, Jonathan A; Hamada, Mahmoud

2009-12-01

The "compass rose pattern" is known to appear in the phase portraits, or scatter diagrams, of the high-frequency returns of financial series. We first show that this pattern is also present in the returns of spot electricity prices. Early researchers investigating these phenomena hoped that these patterns signaled the presence of rich dynamics, possibly chaotic or fractal in nature. Although there is a definite autoregressive and conditional heteroscedasticity structure in electricity returns, we find that after simple filtering no pattern remains. While the series is non-normal in terms of their distribution and statistical tests fail to identify significant chaos, there is evidence of fractal structures in periodic price returns when measured over the trading day. The phase diagram of the filtered returns provides a useful visual check on independence, a property necessary for pricing and trading derivatives and portfolio construction, as well as providing useful insights into the market dynamics.

The particle identification (PID) device in the endcap of the Belle detector will be upgraded to a ring imaging Cherenkov counter (RICH) using aerogel as a radiator at the Belle II experiment. We develop the electronics to read out the 70,000 channels of hit information from the 144-channel hybrid avalanche photodetectors (HAPD), of the aerogel RICH detector. A readout ASIC is developed to digitize the HAPD signals, and was used in a beam test with the prototype detector. The performance and plan of the ASIC is reported in this study. We have also designed the readout electronics for the aerogel RICH, which consist of front-end boards with the ASICs merger boards to collect data from the front-end boards. A front-end board that fits in the actual available space for the aerogel RICH electronics was produced.

SU-E-T-77: Comparison of 2D and 3D Gamma Analysis in Patient-Specific QA for Prostate VMAT Plans

DOE Office of Scientific and Technical Information (OSTI.GOV)

Clemente, F; Perez, C

2014-06-01

Purpose: Patient-specific QA procedures for IMRT and VMAT are traditionally performed by comparing TPS calculations with measured single point values and plane dose distributions by means of gamma analysis. New QA devices permit us to calculate 3D dose distributions on patient anatomy as redundant secondary check and reconstruct it from measurements taken with 2D and 3D detector arrays. 3D dose calculations allow us to perform DVH-based comparisons with clinical relevance, as well as 3D gamma analysis. One of these systems (Compass, IBA Dosimetry) combines traditional 2D with new anatomical-based 3D gamma analysis. This work shows the ability of this systemmore » by comparing 2D and 3D gamma analysis in pre-treatment QA for several VMAT prostate plans. Methods: Compass is capable of calculating dose as secondary check from DICOM TPS data and reconstructing it from measurements taken by a 2D ion chamber array (MatriXX Evolution, IBA Dosimetry). Both 2D and 3D gamma tests are available to compare calculated and reconstructed dose in Compass with TPS RT Dose. Results: 15 VMAT prostate plans have been measured with Compass. Dose is reconstructed with Compass for these plans. 2D gamma comparisons can be done for any plane from dose matrix. Mean gamma passing rates for isocenter planes (axial, coronal, sagittal) are (99.7±0.2)%, (99.9±0.1)%, (99.9±0.1)% for reconstructed dose planes. 3D mean gamma passing rates are (98.5±1.7)% for PTVs, (99.1±1.5)% for rectum, (100.0±0.0)% for bladder, (99.6±0.7)% for femoral heads and (98.1±4.1)% for penile bulb. Conclusion: Compass is a powerful tool to perform a complete pre-treatment QA analysis, from 2D techniques to 3D DVH-based techniques with clinical relevance. All reported values for VMAT prostate plans are in good agreement with TPS values. This system permits us to ensure the accuracy in the delivery of VMAT treatments completing a full patient-specific QA program.« less

2011-08-01

The “standard” Hall A apparatus at Jefferson Lab (TOF and aerogel threshold Cherenkov detectors) does not provide complete identification for proton, kaon and pion. To this aim, a proximity focusing C6F14/CsI RICH (Ring Image Cherenkov) detector has been designed, built, tested and operated to separate kaons from pions with a pion contamination of a few percent up to 2.4 GeV/c. Two quite different experimental investigations have benefitted of the RICH identification: on one side, the high-resolution hypernuclear spectroscopy series of experiments on carbon, beryllium and oxygen, devoted to the study of the lambda-nucleon potential. On the other side, the measurementsmore » of the single spin asymmetries of pion and kaon on a transversely polarized 3He target are of utmost interest in understanding QCD dynamics in the nucleon. We present the technical features of such a RICH detector and comment on the presently achieved performance in hadron identification.« less

Chemical magnetoreception in birds: The radical pair mechanism

PubMed Central

Rodgers, Christopher T.; Hore, P. J.

2009-01-01

Migratory birds travel vast distances each year, finding their way by various means, including a remarkable ability to perceive the Earth's magnetic field. Although it has been known for 40 years that birds possess a magnetic compass, avian magnetoreception is poorly understood at all levels from the primary biophysical detection events, signal transduction pathways and neurophysiology, to the processing of information in the brain. It has been proposed that the primary detector is a specialized ocular photoreceptor that plays host to magnetically sensitive photochemical reactions having radical pairs as fleeting intermediates. Here, we present a physical chemist's perspective on the “radical pair mechanism” of compass magnetoreception in birds. We outline the essential chemical requirements for detecting the direction of an Earth-strength ≈50 μT magnetic field and comment on the likelihood that these might be satisfied in a biologically plausible receptor. Our survey concludes with a discussion of cryptochrome, the photoactive protein that has been put forward as the magnetoreceptor molecule. PMID:19129499

The AMS-02 RICH detector: Performance during ground-based data taking at CERN

Pereira, R.; AMS RICH Collaboration

2011-05-01

The Alpha Magnetic Spectrometer (AMS), whose final version AMS-02 is to be installed on the International Space Station (ISS) in 2011, is a detector designed to measure charged cosmic ray spectra with energies up to the TeV region and with high energy photon detection capability up to a few hundred GeV, using state-of-the art particle identification techniques. Among several detector subsystems, AMS includes a proximity focusing RICH detector enabling precise measurements of particle electric charge (charge identification up to the iron region) and velocity ( Δβ/β˜10-3 for Z=1, Δβ/β˜10-4 for Z=10-20). The optimization of the RICH reconstruction efficiency imposed a dual radiator configuration with 16 NaF tiles ( n=1.33) in the centre and 92 aerogel tiles ( n=1.050) in the outer region, a pixelized detection matrix with 680 Hamamatsu R7600-M16 photomultipliers (each with 4×4 pixels) and a highly reflective conical mirror to increase photon collection. After its assembly at CIEMAT in Madrid, the RICH was taken to CERN in January 2008 and integrated into the full AMS-02 detector. AMS-02 underwent a pre-assembly in 2008 without magnet followed by a second detector assembly with a superconducting magnet in 2009 and the final assembly with a permanent magnet in mid-2010. Cosmic events were acquired in the context of the 2008 pre-assembly and in 2009, and two beam tests from CERN SPS took place in 2010. Results obtained with data from ground-based tests on the RICH performance are presented. A comparison with the aerogel light yield obtained on previous beam tests with a prototype detector is also discussed.

A GEM tracking detector with an extended drift region has been studied as part of an effort to develop new tracking detectors for future experiments at RHIC and for the Electron Ion Collider that is being planned for BNL or JLAB. The detector consists of a triple GEM stack with a 1.6 cm drift region that was operated in a mini TPC type configuration. Both the position and arrival time of the charge deposited in the drift region were measured on the readout plane which allowed the reconstruction of a short vector for the track traversing the chamber. The resulting position and angle information from the vector could then be used to improve the position resolution of the detector for larger angle tracks, which deteriorates rapidly with increasing angle for conventional GEM tracking detectors using only charge centroid information. Two types of readout planes were studied. One was a COMPASS style readout plane with 400 μm pitch XY strips and the other consisted of 2 × 10 mm2 chevron pads. The detector was studied in test beams at Fermilab and CERN, along with additional measurements in the lab, in order to determine its position and angular resolution for incident track angles up to 45 degrees. Several algorithms were studied for reconstructing the vector using the position and timing information in order to optimize the position and angular resolution of the detector for the different readout planes. Applications for large angle tracking detectors at RHIC and EIC are also discussed.

The CLAS12 detector at Thomas Jefferson National Accelerator Facility (TJNAF) is undergoing an upgrade. One of the improvements is the addition of a Ring Imaging Cherenkov (RICH) detector to improve particle identification in the 3-8 GeV/c momentum range. Approximately 400 multi anode photomultiplier tubes (MAPMTs) are going to be used to detect Cherenkov Radiation in the single photoelectron spectra (SPS). The SPS of each pixel of all MAPMTs have been fitted to a mathematical model of roughly 45 parameters for 4 HVs, 3 OD. Out of those parameters, 9 can be used to evaluate the PMTs performance and placement in the detector. To help analyze data when the RICH is operational, a GUI application was written in Java using Swing and detector packages from TJNAF. To store and retrieve the data, a MySQL database program was written in Java using the JDBC package. Using the database, the GUI pulls the values and produces histograms and graphs for a selected PMT at a specific HV and OD. The GUI will allow researchers to easily view a PMT's performance and efficiency to help with data analysis and ring reconstruction when the RICH is finished.

Jefferson Lab (Jlab) is performing a large-scale upgrade to its Continuous Electron Beam Accelerator Facility (CEBAF) up to 12GeV beams. The Large Acceptance Spectrometer (CLAS12) in Hall B is being upgraded and a new hybrid Ring Imaging Cherenkov (RICH) detector is being developed to provide better kaon - pion separation throughout the 3 to 8 GeV/c momentum range. This detector will be used for a variety of Semi-Inclusive Deep Inelastic Scattering experiments. Cherenkov light can be accurately detected by a large array of sophisticated Multi-Anode Photomultiplier Tubes (MA-PMT) and heavier particles, like kaons, will span the inner radii. We are presenting our work on the creation of the RICH's geometry within the CLAS12 java framework. This development is crucial for future calibration, reconstructions and analysis of the detector.

An Electron-Ion Collider (EIC) has been proposed to further explore the strong force and QCD, focusing on the structure and the interaction of gluon-dominated matter. A generic detector R&D program (EIC PID consortium) for the particle identification in EIC experiments was formed to explore technologically advanced solutions in this scope. In this context two Ring Imaging Cherenkov (RICH) counters have been proposed: a modular RICH detector which consists of an aerogel radiator, a Fresnel lens, a mirrored box, and pixelated photon sensor; a dual-radiator RICH, consisting of an aerogel radiator and C 2F 6 gas in a mirror-focused configuration. Asmore » a result, we present the simulations of the two detectors and their estimated performance.« less

The paper discusses the importance of particle identification in particle physics experiments, and reviews the impact of ring imaging Cherenkov (RICH) counters in experiments that are currently running, or are under construction. Several analysis methods are discussed that are needed to calibrate a RICH counter, and to align its components with the rest of the detector. Finally, methods are reviewed on how to employ the collected data to efficiently separate one particle species from the other.

The objective of this study was to examine the relationships among health promotion behaviors, compassion fatigue, burnout, and compassion satisfaction among nurses practicing in a community medical center. Compassion fatigue and burnout are significant nursing stressors. Programs are available to offset the negative consequence of compassion fatigue and burnout and enhance compassion satisfaction, yet there remains a paucity of literature examining the relationships between health promotion behaviors, compassion fatigue, burnout, and compassion satisfaction. A nonexperimental design using a convenience sample of nurses completed the Health Promoting Lifestyle Profile II, the Professional Quality of Life Scale, and a demographic data sheet. Statistically significant relationships among health promotional behaviors and compassion fatigue, compassion satisfaction, and burnout were identified. Compassion fatigue, burnout, and compassion satisfaction are outcomes associated with nursing practice. Support for engagement in health promotional behaviors may contribute to nurses' well-being in counteracting compassion fatigue and burnout and enhancing compassion satisfaction.

Commissioning and first results of the NA62 RICH

The NA62 experiment at CERN has been constructed to measure the ultra rare charged kaon decay into a charged pion and two neutrinos with a 10% uncertainty. The main background is the charged kaon decay into a muon and a neutrino which is suppressed by kinematic tools using a magnetic spectrometer and by the different stopping power of muons and pions in the calorimeters. A RICH detector is needed to further suppress the μ+ contamination in the π+ sample by a factor of at least 100 between 15 and 35 GeV/c momentum, to measure the pion crossing time with a resolution of about 100 ps and to produce the trigger for a charged track. The detector consists of a 17 m long tank (vessel), filled with neon gas at atmospheric pressure. Cherenkov light is reflected by a mosaic of 20 spherical mirrors with 17 m focal length, placed at the downstream end, and collected by 1952 photomultipliers (PMTs) placed at the upstream end. The RICH detector installation was completed in the summer of 2014 and the detector was used for the first time during the pilot run at the end of 2014. The RICH was then operated during the NA62 Commissioning Run in 2015 and in the 2016 Physics Run. It must be noted that in 2014 and 2015 the RICH mirror alignment was not optimal and the need of a better performance in the pion-muon separation was the main reason for the detector maintenance carried out in the 2015-2016 winter shutdown. In this contribution the construction of the detector will be described and the performance reached during the 2014-2015 data-taking will be discussed; preliminary results from the 2016 data-taking will also be shown.

Compassion fatigue and burnout can impact on performance of nurses. This paper explores the relationship between self-compassion, self-judgement, self-kindness, compassion, professional quality of life, and wellbeing among community nurses. To measure associations between self-compassion, compassion fatigue, wellbeing, and burnout in community nurses. Quantitative data were collected using standardised psychometric questionnaires: (1) Professional Quality of Life Scale; (2) Self-Compassion Scale; (3) short Warwick Edinburgh Mental Wellbeing Scale; (4) Compassion For Others Scale, used to measure relationships between self-compassion, compassion fatigue, wellbeing, and burnout. A cross sectional sample of registered community nurses (n=37) studying for a postgraduate diploma at a University in the North of England took part in this study. Results show that community nurses who score high on measures of self-compassion and wellbeing, also report less burnout. Greater compassion satisfaction was also positively associated with compassion for others, and wellbeing, whilst also being negatively correlated with burnout. High levels of self-compassion were linked with lower levels of burnout. Furthermore when community nurses have greater compassion satisfaction they also report more compassion for others, increased wellbeing, and less burnout. The implications of this are discussed alongside suggestions for the promotion of greater compassion. Copyright © 2016 Elsevier Ltd. All rights reserved.

MICADO is a E-ELT first light near-infrared imager. It will work at the diffraction limit of the telescope thanks to multi-conjugate adaptive optics (MCAO) and single-conjugate adaptive optics (SCAO) modes provided inside the MAORY AO module. The SCAO capability is a joint development by the MICADO and MAORY consortia, lead by MICADO, and is motivated by scientific programs for which SCAO will deliver the best AO performance (e.g. exoplanets, solar system science, bright AGNs, etc). Shack-Hartmann (SH) or Pyramid WFS were both envisioned for the wavefront measurement of the SCAO mode. In addition to WFS design considerations, numerical simulations are therefore needed to trade-off between these two WFS. COMPASS (COMputing Platform for Adaptive optics SyStems) is a GPU-based adaptive optics end-to-end simulation platform allowing us to perform numerical simulations in various modes (SCAO, LTAO, MOAO, MCAO...). COMPASS was originally bound to Yorick for its user interface and a major upgrade has been recently done to now bind to Python allowing a better long term support to the community. Thanks to the speed of computation of COMPASS we were able to span quickly a very large parameters of space at the E-ELT scale. We present the results of the study between WFS choice (SH or Pyramid), WFS parameters (detector noise, guide star magnitude, number of subapertures, number of controlled modes...), turbulence conditions and AO controls for the MICADO-MAORY SCAO mode.

Burnout has numerous negative consequences for nurses, potentially impairing their ability to deliver compassionate patient care. However, the association between burnout and compassion and, more specifically, barriers to compassion in medicine is unclear. This article evaluates the associations between burnout and barriers to compassion and examines whether dispositional self-compassion might mitigate this association. Consistent with prior work, the authors expected greater burnout to predict greater barriers to compassion. We also expected self-compassion - the ability to be kind to the self during times of distress - to weaken the association between burnout and barriers to compassion among nurses. Registered nurses working in New Zealand medical contexts were recruited using non-random convenience sampling. Following consent, 799 valid participants completed a cross-sectional survey including the Copenhagen Burnout Inventory, the Barriers to Physician Compassion scale, and a measure of dispositional self-compassion. As expected, greater burnout predicted greater barriers to compassion while self-compassion predicted fewer barriers. However, self-compassion mitigated the association between burnout and burnout related barriers to compassion (but not other barriers). The interaction suggested that suggested that the association was stronger (rather than weaker) among those with greater self-compassion. Understanding the lack of compassion and the effects of burnout in patient care are priorities in health. This report extends evidence on the association between burnout and compassion-fatigue to show that burnout also predicts the experience of specific barriers to compassion. While self-compassion predicted lower burnout and barriers, it may not necessarily reduce the extent to which burnout contributes to the experience of barriers to compassion in medicine. Implications for understanding how burnout manifests in barriers to clinical compassion, interventions and professional training, and future directions in nursing are discussed.

A heuristic model of enactive compassion.

PubMed

Halifax, Joan

2012-06-01

This article is an investigation of the possibility that compassion is not a discrete feature but an emergent and contingent process that is at its base enactive. Compassion must be primed through the cultivation of various factors. This article endeavors to identify interdependent components of compassion. This is particularly relevant for those in the end-of-life care professions, wherein compassion is an essential factor in the care of those suffering from a catastrophic illness or injury. The Halifax Model of Compassion is presented here as a new vision of compassion with particular relevance for the training of compassion in clinicians. Compassion is generally valued as a prosocial mental quality. The factors that foster compassion are not well understood, and the essential components of compassion have not been sufficiently delineated. Neuroscience research on compassion has only recently begun, and there is little clinical research on the role of compassion in end-of-life care. Compassion is in general seen as having two main components: the affective feeling of caring for one who is suffering and the motivation to relieve suffering. This definition of compassion might impose limitations and will, therefore, have consequences on how one trains compassion in clinicians and others. It is the author's premise that compassion is dispositionally enactive (the interactions between living organisms and their environments, i.e., the propensity toward perception-action in relation to one's surrounds), and it is a process that is contingent and emergent.

In 2015, the LHCb experiment established a new and unique software trigger strategy with the purpose of increasing the purity of the signal events by applying the same algorithms online and offline. To achieve this, real-time calibration and alignment of all LHCb sub-systems is needed to provide vertexing, tracking, and particle identification of the best possible quality. The calibration of the refractive index of the RICH radiators, the calibration of the Hybrid Photon Detector image, and the alignment of the RICH mirror system, are reported in this contribution. The stability of the RICH performance and the particle identification performance are also discussed.

The purpose of this study was to identify the effects of compassion satisfaction and social support in the relationship between compassion fatigue and burnout among hospital nurses. The participants were 430 nurses working in general hospitals. Data were collected with self-administrated questionnaires and analyzed by hierarchical multiple regression. (a) Compassion fatigue had a significant positive effect on burnout; (b) social support and compassion satisfaction had negative effects on burnout, and (c) social support and compassion satisfaction did not moderate the effects of compassion fatigue on burnout. These findings provide strong empirical evidence for the importance of compassion fatigue, compassion satisfaction and social support in explaining burnout of nurses. Also, it would be of great value to further define compassion fatigue and compassion satisfaction even though these concepts are not accepted in the realities of health care.

Compassion fatigue among nurses working with older adults.

PubMed

Kolthoff, Kay L; Hickman, Susan E

Nurses who care for older patients are exposed to significant suffering and loss that can lead to the development of compassion fatigue and burnout. An exploratory descriptive study was conducted to assess compassion fatigue, burnout, and compassion satisfaction in a group of 42 nurses who worked on a geriatric medicine unit using the Professional Quality of Life (ProQOL) compassion satisfaction and compassion fatigue 5 scale. Nurses reported average levels of compassion fatigue, burnout, and compassion satisfaction. However, new nurses reported higher levels of compassion fatigue (p < .01) and burnout (p = .02) than experienced nurses. Findings suggest the need to purposely build a supportive environment that focuses on new nurses to reduce compassion fatigue and burnout while enhancing compassion satisfaction.

Relationships between nurses' empathy, self-compassion and dimensions of professional quality of life: A cross-sectional study.

Duarte, Joana; Pinto-Gouveia, José; Cruz, Bárbara

Job stress and burnout are common among healthcare professionals, and nurses in particular. In addition to the heavy workload and lack of recourses, nurses are also confronted with emotionally intense situations associated with illness and suffering, which require empathic abilities. Although empathy is one of the core values in nursing, if not properly balanced it can also have detrimental consequences, such as compassion fatigue. Self-compassion, on the other hand, has been shown to be a protective factor for a wide range of well-being indicators and has been associated with compassion for others. The main goal of this study was to explore how empathy and self-compassion related to professional quality of life (compassion satisfaction, compassion fatigue and burnout). In addition, we wanted to test whether self-compassion may be a protective factor for the impact of empathy on compassion fatigue. Using a cross-sectional design, 280 registered nurses from public hospitals in Portugal's north and center region were surveyed. Professional quality of life (Professional Quality of Life), empathy (Interpersonal Reactivity Index) and self-compassion (Self-compassion Scale) were measured using validated self-report measures. Correlations and regression analyses showed that empathy and self-compassion predicted the three aspects of professional quality of life. Empathic concern was positively associated with compassion satisfaction as well as with compassion fatigue. Mediation models suggested that the negative components of self-compassion explain some of these effects, and self-kindness and common humanity were significant moderators. The same results were found for the association between personal distress and compassion fatigue. High levels of affective empathy may be a risk factor for compassion fatigue, whereas self-compassion might be protective. Teaching self-compassion and self-care skills may be an important feature in interventions that aim to reduce burnout and compassion fatigue. Copyright © 2016 Elsevier Ltd. All rights reserved.

The purpose of this study was twofold: (a) to determine the prevalence of compassion satisfaction, compassion fatigue, and burnout in emergency department nurses throughout the United States and (b) to examine which demographic and work-related components affect the development of compassion satisfaction, compassion fatigue, and burnout in this nursing specialty. This was a nonexperimental, descriptive, and predictive study using a self-administered survey. Survey packets including a demographic questionnaire and the Professional Quality of Life Scale version 5 (ProQOL 5) were mailed to 1,000 selected emergency nurses throughout the United States. The ProQOL 5 scale was used to measure the prevalence of compassion satisfaction, compassion fatigue, and burnout among emergency department nurses. Multiple regression using stepwise solution was employed to determine which variables of demographics and work-related characteristics predicted the prevalence of compassion satisfaction, compassion fatigue, and burnout. The α level was set at .05 for statistical significance. The results revealed overall low to average levels of compassion fatigue and burnout and generally average to high levels of compassion satisfaction among this group of emergency department nurses. The low level of manager support was a significant predictor of higher levels of burnout and compassion fatigue among emergency department nurses, while a high level of manager support contributed to a higher level of compassion satisfaction. The results may serve to help distinguish elements in emergency department nurses' work and life that are related to compassion satisfaction and may identify factors associated with higher levels of compassion fatigue and burnout. Improving recognition and awareness of compassion satisfaction, compassion fatigue, and burnout among emergency department nurses may prevent emotional exhaustion and help identify interventions that will help nurses remain empathetic and compassionate professionals. © 2015 Sigma Theta Tau International.

Compassion fatigue, burnout, and compassion satisfaction among Colorado child protection workers.

The goal of this study was to understand better the risk of compassion fatigue (the trauma suffered by the helping professional) and burnout (emotional exhaustion, depersonalization, and reduced sense of personal accomplishment), and the potential for compassion satisfaction (the fulfillment from helping others and positive collegial relationships) among Colorado county child protection staff using the Compassion Satisfaction/Fatigue Self-Test [Figley, C. R., & Stamm, B. H. (1996). Psychometric review of Compassion Fatigue Self-Test. In B. H. Stamm (Ed.), Measurement of stress, trauma, and adaptation (pp. 127-130). Lutherville, MD: Sidran Press]. An additional goal was to test the relationship of these three constructs to each other. A self-report instrument developed by Stamm and Figley was used to measure the risk of compassion fatigue and burnout and the potential for compassion satisfaction among 363 child protection staff participating in a secondary trauma training seminar. Participants were significantly more likely to have high risk of compassion fatigue, extremely low risk of burnout, and good potential for compassion satisfaction. Participants with high compassion satisfaction had lower levels of compassion fatigue (p=.000; mean=35.73 high compassion satisfaction group, mean=43.56 low group) and lower levels of burnout (p=.000; mean=32.99 high compassion satisfaction group, mean=41.69 low group). Approximately 50% of Colorado county child protection staff suffered from "high" or "very high" levels of compassion fatigue. The risk of burnout was considerably lower. More than 70% of staff expressed a "high" or "good" potential for compassion satisfaction. We believe compassion satisfaction may help mitigate the effects of burnout.

Understanding the roles of self-esteem, self-compassion, and fear of self-compassion in eating disorder pathology: an examination of female students and eating disorder patients.

The present study examined the relative contributions of self-compassion, fear of self-compassion, and self-esteem in eating disorder pathology. One-hundred and fifty-five female undergraduate students and 97 females entering eating disorder treatment completed the Self-Compassion Scale, Fears of Compassion Scale, Rosenberg Self-Esteem Inventory, and Eating Disorder Examination Questionnaire. T-tests revealed that the patient group had lower mean self-compassion and higher mean fear of self-compassion than the student group. When controlling for self-esteem, high fear of self-compassion emerged as the strongest predictor of eating disorder pathology in the patient group, whereas low self-compassion was the strongest predictor in the student group. These preliminary results suggest that targeting fear of self-compassion may be important when intervening with individuals suffering from an eating disorder, whereas building self-compassion may be a valuable approach for eating disorder prevention.

This meta-narrative review, conducted according to the RAMESES (Realist And Meta-narrative Evidence Syntheses: Evolving Standards) standards, critically examines the construct of self-compassion to determine if it is an accurate target variable to mitigate work-related stress and promote compassionate caregiving in healthcare providers. PubMed, Medline, CINAHL, PsycINFO, and Web of Science databases were searched. Studies were coded as referring to: (1) conceptualisation of self-compassion; (2) measures of self-compassion; (3) self-compassion and affect; and (4) self-compassion interventions. A narrative approach was used to evaluate self-compassion as a paradigm. Sixty-nine studies were included. The construct of self-compassion in healthcare has significant limitations. Self-compassion has been related to the definition of compassion, but includes limited facets of compassion and adds elements of uncompassionate behavior. Empirical studies use the Self-Compassion Scale, which is criticised for its psychometric and theoretical validity. Therapeutic interventions purported to cultivate self-compassion may have a broader effect on general affective states. An alleged outcome of self-compassion is compassionate care; however, we found no studies that included patient reports on this primary outcome. We critically examine and delineate self-compassion in healthcare providers as a composite of common facets of self-care, healthy self-attitude, and self-awareness rather than a construct in and of itself. © 2017 The International Association of Applied Psychology.

Cultivation of compassion is a useful way to treat mental problems, but some individuals show resistance. Fears of compassion can be an obstacle for clinicians when providing psychotherapy, and for clients when engaging in interpersonal relationships. Despite its importance, a Japanese version of fears of compassion scales (for others, from others, and for self) has not yet been developed. This study developed a Japanese version of the Fears of Compassion Scales and tested its reliability and validity. This study used a cross-sectional design, and a self-report procedure for collecting data. A total of 485 students (121 males and 364 females) answered self-report questionnaires, including the draft Fears of Compassion Scales-Japanese version. There were distinctive factor structures for fear of compassion from others, and for self. The fear of compassion from others scale consisted of concern about compassion from others and avoidance of compassion from others. All scales had good internal consistency, test-retest reliability, face validity, and construct validity. Discrimination and difficulty were also calculated. These results indicate that the Fears of Compassion Scales-Japanese version is a well-constructed and useful measure to assess fears of compassion and the existence of cultural differences in fears of compassion.

Self-compassion training for binge eating disorder: a pilot randomized controlled trial.

PubMed

Kelly, Allison C; Carter, Jacqueline C

2015-09-01

The present pilot study sought to compare a compassion-focused therapy (CFT)-based self-help intervention for binge eating disorder (BED) to a behaviourally based intervention. Forty-one individuals with BED were randomly assigned to 3 weeks of food planning plus self-compassion exercises; food planning plus behavioural strategies; or a wait-list control condition. Participants completed weekly measures of binge eating and self-compassion; pre- and post-intervention measures of eating disorder pathology and depressive symptoms; and a baseline measure assessing fear of self-compassion. Results showed that: (1) perceived credibility, expectancy, and compliance did not differ between the two interventions; (2) both interventions reduced weekly binge days more than the control condition; (3) the self-compassion intervention reduced global eating disorder pathology, eating concerns, and weight concerns more than the other conditions; (4) the self-compassion intervention increased self-compassion more than the other conditions; and (5) participants low in fear of self-compassion derived significantly more benefits from the self-compassion intervention than those high in fear of self-compassion. Findings offer preliminary support for the usefulness of CFT-based interventions for BED sufferers. Results also suggest that for individuals to benefit from self-compassion training, assessing and lowering fear of self-compassion will be crucial. Individuals with BED perceive self-compassion training self-help interventions, derived from CFT, to be as credible and as likely to help as behaviourally based interventions. The cultivation of self-compassion may be an effective approach for reducing binge eating, and eating, and weight concerns in individuals with BED. Teaching individuals with BED CFT-based self-help exercises may increase their self-compassion levels over a short period of time. It may be important for clinicians to assess and target clients' fear of self-compassion for clients to benefit from self-compassion training interventions. © 2014 The British Psychological Society.

Pediatric novice nurses: examining compassion fatigue as a mediator between stress exposure and compassion satisfaction, burnout, and job satisfaction.

PubMed

Meyer, Rika M L; Li, Angela; Klaristenfeld, Jessica; Gold, Jeffrey I

2015-01-01

We investigated whether compassion fatigue mediated associations between nurse stress exposure and job satisfaction, compassion satisfaction, and burnout, controlling for pre-existing stress. The Life Events Checklist was administered to 251 novice pediatric nurses at the start of the nurse residency program (baseline) and 3 months after to assess pre-existing and current stress exposure. Compassion satisfaction, compassion fatigue, and burnout were assessed 3 months after baseline and job satisfaction 6 months after. Stress exposure significantly predicted lower compassion satisfaction and more burnout. Compassion fatigue partially mediated these associations. Results demonstrate a need for hospitals to prevent compassion fatigue in healthcare providers. Copyright © 2015 Elsevier Inc. All rights reserved.

Objectives Cultivation of compassion is a useful way to treat mental problems, but some individuals show resistance. Fears of compassion can be an obstacle for clinicians when providing psychotherapy, and for clients when engaging in interpersonal relationships. Despite its importance, a Japanese version of fears of compassion scales (for others, from others, and for self) has not yet been developed. This study developed a Japanese version of the Fears of Compassion Scales and tested its reliability and validity. Design This study used a cross-sectional design, and a self-report procedure for collecting data. Methods A total of 485 students (121 males and 364 females) answered self-report questionnaires, including the draft Fears of Compassion Scales—Japanese version. Results There were distinctive factor structures for fear of compassion from others, and for self. The fear of compassion from others scale consisted of concern about compassion from others and avoidance of compassion from others. All scales had good internal consistency, test-retest reliability, face validity, and construct validity. Discrimination and difficulty were also calculated. Conclusions These results indicate that the Fears of Compassion Scales—Japanese version is a well-constructed and useful measure to assess fears of compassion and the existence of cultural differences in fears of compassion.

Building compassion literacy: Enabling care in primary health care nursing.

PubMed

Burridge, Letitia Helen; Winch, Sarah; Kay, Margaret; Henderson, Amanda

This paper introduces the concept of compassion literacy and discusses its place in nursing within the general practice setting. Compassion literacy is a valuable competency for sustaining the delivery of high quality care. Being compassion literate enables practice nurses to provide compassionate care to their patients and to recognise factors that may constrain this. A compassion literate practice nurse may be more protected from compassion fatigue and its negative consequences. Understanding how to enable self-compassion and how to support the delivery of compassionate care within the primary care team can enhance the care experienced by the patient while improving the positive engagement and satisfaction of the health professionals. The capacity to deliver compassionate care can be depleted by the day-to-day demands of the clinical setting. Compassion literacy enables the replenishing of compassion, but the development of compassion literacy can be curtailed by personal and workplace barriers. This paper articulates why compassion literacy should be an integral aspect of practice nursing and considers strategies for enabling compassion literacy to develop and thrive within the workplace environment. Compassion literacy is also a valuable opportunity for practice nurses to demonstrate their key role within the multidisciplinary team of general practice, directly enhancing the quality of the care delivered.

Hospice care professionals (HCPs) experience a large number of stressors in their work settings. The purpose of this study was to investigate the relationship between self-care, compassion fatigue, burnout, and compassion satisfaction among HCPs. Thirty-seven HCPs were surveyed regarding their levels of compassion satisfaction, compassion fatigue, and burnout. Respondents also reported the types of self-care activities in which they took part. Results indicated a relationship between self-care strategies and lower levels of burnout and compassion fatigue, and higher levels of compassion satisfaction. Several suggestions are offered for continued research and practice in the hospice care field.

A description of the test methods used at the National Bureau of Standards for determining the characteristics of aircraft compasses is given. The methods described are particularly applicable to compasses in which mineral oil is used as the damping liquid. Data on the viscosity and density of certain mineral oils used in United States Navy aircraft compasses are presented. Characteristics of Navy aircraft compasses IV to IX and some other compasses are shown for the range of temperatures experienced in flight. Results of flight tests are presented. These results indicate that the characteristic most desired in a steering compass is a short period and, in a check compass, a low overswing.

Helping the self help others: self-affirmation increases self-compassion and pro-social behaviors

Reflecting on an important personal value in a self-affirmation activity has been shown to improve psychological functioning in a broad range of studies, but the underlying mechanisms for these self-affirmation effects are unknown. Here we provide an initial test of a novel self-compassion account of self-affirmation in two experimental studies. Study 1 shows that an experimental manipulation of self-affirmation (3-min of writing about an important personal value vs. writing about an unimportant value) increases feelings of self-compassion, and these feelings in turn mobilize more pro-social behaviors to a laboratory shelf-collapse incident. Study 2 tests and extends these effects by evaluating whether self-affirmation increases feelings of compassion toward the self (consistent with the self-compassion account) or increases feelings of compassion toward others (an alternative other-directed compassion account), using a validated storytelling behavioral task. Consistent with a self-compassion account, Study 2 demonstrates the predicted self-affirmation by video condition interaction, indicating that self-affirmation participants had greater feelings of self-compassion in response to watching their own storytelling performance (self-compassion) compared to watching a peer’s storytelling performance (other-directed compassion). Further, pre-existing levels of trait self-compassion moderated this effect, such that self-affirmation increased self-compassionate responses the most in participants low in trait self-compassion. This work suggests that self-compassion may be a promising mechanism for self-affirmation effects, and that self-compassionate feelings can mobilize pro-social behaviors. PMID:24860534

This project aims to exploit the parallel computing power of a commercial Graphics Processing Unit (GPU) to implement fast pattern matching in the Ring Imaging Cherenkov (RICH) detector for the level 0 (L0) trigger of the NA62 experiment. In this approach, the ring-fitting algorithm is seedless, being fed with raw RICH data, with no previous information on the ring position from other detectors. Moreover, since the L0 trigger is provided with a more elaborated information than a simple multiplicity number, it results in a higher selection power. Two methods have been studied in order to reduce the data transfer latency from the readout boards of the detector to the GPU, i.e., the use of a dedicated NIC device driver with very low latency and a direct data transfer protocol from a custom FPGA-based NIC to the GPU. The performance of the system, developed through the FPGA approach, for multi-ring Cherenkov online reconstruction obtained during the NA62 physics runs is presented.

Studies have investigated burnout and compassion fatigue among nurses and effects in the nursing profession. However, there are limited investigations of burnout and compassion fatigue among undergraduate nursing students in South Africa, as nursing students may experience distressful situations during their nursing education course, which may have an impact during their training and in their profession as they graduate. The purpose of this descriptive study was to describe compassion satisfaction, compassion fatigue and burnout among undergraduate nursing students at a tertiary nursing institution. A quantitative descriptive study was conducted to describe compassion satisfaction, compassion fatigue and burnout among undergraduate nursing students at a tertiary nursing institution in KwaZulu-Natal. Convenience sampling was used. Sixty-seven undergraduate students (26 third-year and 41 fourth-year nursing students) took the self-test Professional Quality of Life Scale (ProQOL). The study results indicate that undergraduate students experienced average levels of compassion fatigue, burnout and compassion satisfaction. As shown in the study, some of the undergraduate students are experiencing compassion fatigue and burnout, associated with relieving suffering of others. Therefore, knowledge of compassion fatigue and burnout and the coping strategies should be part of nursing training.

The LHCb experiment is dedicated to precision measurements of CP violation and rare decays of B hadrons at the Large Hadron Collider (LHC) at CERN (Geneva). The second long shutdown of the LHC is currently scheduled to begin in 2019. During this period the LHCb experiment with all its sub-detectors will be upgraded in order to run at an instantaneous luminosity of 2 × 10^{33} cm ^{-2} s ^{-1} , about a factor 5 higher than the current luminosity, and to read out data at a rate of 40MHz into a flexible software-based trigger. The Ring Imaging CHerenkov (RICH) system will require new photon detectors and modifications to the optics of the upstream detector. Tests of the prototype of the smallest constituent of the new RICH system have been performed during testbeam sessions at the North Area test beam facility at CERN in the last years.

Despite the increasingly crucial role of the healthcare workforce and volunteers working in hospice and palliative care (HPC), very little is known about factors that promote or limit the positive outcomes associated with practicing compassion. The purpose of this study was to: 1) understand the complex relationships among Compassion Satisfaction, Compassion Fatigue and Burnout within the hospice and palliative care workforce and 2) explore how key practice characteristics - practice status, professional affiliation, and principal institution - interact with the measured constructs of Compassion Satisfaction, Compassion Fatigue and Burnout. Self-reported measures of Compassion Satisfaction, Compassion Fatigue and Burnout, using validated scales, as well as questions to describe socio-demographic profiles and key practice characteristics were obtained. A national survey of HPC workers, comprising clinical, administrative, allied health workers and volunteers, was completed. Respondents from hospital, community-based and care homes informed the results of our study (n = 630). Our results indicate a significant negative correlation between Compassion Satisfaction and Burnout (r = -0.531, p < 0.001) and between Compassion Satisfaction and Compassion Fatigue (r = -0.208, p < 0.001), and a significant positive correlation between Burnout and Compassion Fatigue (r = 0.532, p < 0.001). Variations in self-reported levels of the above constructs were noted by key practice characteristics. Levels of all three constructs are significantly, but differentially, affected by type of service provided, principal institution, practice status and professional affiliation. Results indicate that health care systems could increase the prevalence of Compassion Satisfaction through both policy and institutional level programs to support HPC professionals in their jurisdictions.

Role of compassion competence among clinical nurses in professional quality of life.

The study aimed to explore measurable compassion competence among nurses and to examine the relationships between nurses' compassion competence and levels of compassion satisfaction, compassion fatigue and secondary traumatic stress. Compassion is a vital asset in the nursing profession. It is necessary to explore whether compassion competence is a factor influencing professional quality of life. This study utilized a multicenter descriptive cross-sectional survey. Data were collected from 680 nurses. Professional quality of life based on nurses' general characteristics showed a significant difference in the subjects' age, marital status, education, and total clinical experience. In addition, compassion competence had a significant positive correlation with compassion satisfaction and STS, whereas it had a significant negative correlation with burnout. Compassion competence was a factor influencing compassion satisfaction and burnout in professional quality of life. Our study included nurses with at least 1 year of clinical experience in a single cultural area, which limits its widespread applicability. To improve generalizability, future studies should include clinical nurses of various races, working in diverse cultural areas and with various levels of experience (including entry-level nurses and nursing students). Compassion competence of clinical nurses was a predictive factor for professional quality of life. Hospital administrators, nurse leaders and policy makers should develop and adopt nurse-retaining strategies that focus on improving nurses' compassion competence in order to reduce their burnout. We recommend the development of educational programmes to improve nurses' compassion competence and thereby enhance their professional quality of life. © 2016 International Council of Nurses.

In the current work, graphite electrodes comprising PVDF binder and carbon black are subjected to characterization. An energy selective backscatter detector is used to localize carbon black and fluorine of PVDF. Therefore, it is necessary to distinguish between graphite, amorphous carbon and fluorine rich regions. Typically, an angular selective backscatter detector is employed to obtain an image providing the material contrast of the sample. Suitable materials for that detector are e.g. alloys to observe intermetallic phases, semiconductor for ;channeling contrast;, or imaging SiO2 and Au nanoparticles in biological cells. However, this detector cannot be used to distinguish between light elements with low atomic numbers, such as C to P. In addition, the contrast of fluorine rich regions and graphite is poor in normal in-lens images due to the low difference of the atomic mass between C and F. The aim of this study is to enhance the contrast of fluorine rich regions to graphite to carbon black. Therefore, the energy selective backscatter detector is used and its advantages and setup is described. Finally this technique is applied to investigate 400 μm thick cross-sections of graphite electrodes dried at different temperatures and obtain the carbon black distribution.

Introduction. Compassion fatigue is a concept used with increasing frequency in the nursing literature. The objective of this paper is to identify common themes across the literature and to apply these themes, and an existing model of compassion fatigue, to informal caregivers for family members with dementia. Findings. Caregivers for family members with dementia may be at risk for developing compassion fatigue. The model of compassion fatigue provides an informative framework for understanding compassion fatigue in the informal caregiver population. Limitations of the model when applied to this population were identified as traumatic memories and the emotional relationship between parent and child, suggesting areas for future research. Conclusions. Research is needed to better understand the impact of compassion fatigue on informal caregivers through qualitative interviews, to identify informal caregivers at risk for compassion fatigue, and to provide an empirical basis for developing nursing interventions for caregivers experiencing compassion fatigue.

Psychologists tend to report high levels of occupational stress, with serious implications for themselves, their clients, and the discipline as a whole. Recent research suggests that self-compassion is a promising construct for psychologists in terms of its ability to promote psychological wellbeing and resilience to stress; however, the potential benefits of self-compassion are yet to be thoroughly explored amongst this occupational group. Additionally, while a growing body of research supports self-compassion as a key predictor of psychopathology, understanding of the processes by which self-compassion exerts effects on mental health outcomes is limited. Structural equation modelling (SEM) was used to test an emotion regulation model of self-compassion and stress among psychologists, including postgraduate trainees undertaking clinical work (n = 198). Self-compassion significantly negatively predicted emotion regulation difficulties and stress symptoms. Support was also found for our preliminary explanatory model of self-compassion, which demonstrates the mediating role of emotion regulation difficulties in the self-compassion-stress relationship. The final self-compassion model accounted for 26.2% of variance in stress symptoms. Implications of the findings and limitations of the study are discussed. PMID:26207900

Affective and physiological responses to the suffering of others: compassion and vagal activity.

Stellar, Jennifer E; Cohen, Adam; Oveis, Christopher; Keltner, Dacher

Compassion is an affective response to another's suffering and a catalyst of prosocial behavior. In the present studies, we explore the peripheral physiological changes associated with the experience of compassion. Guided by long-standing theoretical claims, we propose that compassion is associated with activation in the parasympathetic autonomic nervous system through the vagus nerve. Across 4 studies, participants witnessed others suffer while we recorded physiological measures, including heart rate, respiration, skin conductance, and a measure of vagal activity called respiratory sinus arrhythmia (RSA). Participants exhibited greater RSA during the compassion induction compared with a neutral control (Study 1), another positive emotion (Study 2), and a prosocial emotion lacking appraisals of another person's suffering (Study 3). Greater RSA during the experience of compassion compared with the neutral or control emotion was often accompanied by lower heart rate and respiration but no difference in skin conductance. In Study 4, increases in RSA during compassion positively predicted an established composite of compassion-related words, continuous self-reports of compassion, and nonverbal displays of compassion. Compassion, a core affective component of empathy and prosociality, is associated with heightened parasympathetic activity. (c) 2015 APA, all rights reserved).

To explore the level of and the association between, compassion satisfaction and fatigue of paediatric nurses; to determine the association between personality traits and compassion satisfaction and fatigue; to identify the determinants of compassion satisfaction and fatigue. Paediatric nurses are prone to experiencing compassion fatigue associated with caring for children with illness and their families, yet its connection with nurses' personality traits remains unknown. A cross-sectional descriptive study design was used. The data collection used three instruments measuring socio-demography, responses to the compassion satisfaction and fatigue test and the revised NEO personality inventory. The study used descriptive, correlation and multiple regression analysis for the data collected between April - July 2014. From 173 female paediatric nurses, two-thirds worked in critical care units and indicated a satisfactory level of compassion satisfaction and a low level of compassion fatigue, despite a lack of association between the two concepts. Four determinants-agreeableness, extraversion, conscientiousness and engaging with outdoor activities-were predictive and explained 43.6% of total variance of compassion satisfaction. Two risk factors of compassion fatigue identified were less emotional stability and singlehood (marital status) and these explained 26.1% of total variance of compassion fatigue. Support for improving agreeableness and emotional stability in paediatric nurses' workplaces including involvement in the outdoor activities and an increase in social connection may enhance compassion satisfaction and prevent exhaustive compassion fatigue. © 2017 John Wiley & Sons Ltd.

Compassion satisfaction and compassion fatigue influence nurses' intention to stay or leave nursing. Identification of compassion satisfaction or fatigue in critical care nurses is important in this high turnover workforce. The aim of this study was to examine factors predicting and contributing to compassion satisfaction and compassion fatigue experienced by critical care nurses in Australian intensive care units. A self-reported cross-sectional survey using an established tool collected data from critical care nurses of two adult Australian intensive care units. Overall, these critical care nurses reported what Professional Quality of Life Scale guidelines designated as 'average' levels of compassion satisfaction and burnout, and 'low' levels of Secondary Traumatic Stress (STS). Compared to Site B, nurses at Site A had significantly higher compassion satisfaction (p=0.008) and lower STS scores (p=0.025), with site significantly predictive for compassion satisfaction (p<0.024) and STS (p<0.002). Nurses with postgraduate qualifications had significantly higher compassion satisfaction scores (p=0.027), and compassion satisfaction significantly increased with increasing duration of practice (p=0.042) as a nurse and in their current ICU (p=0.038). Burnout scores significantly reduced with increasing age, years of tenure and practice; burnout was predicted by lower years of tenure (p<0.016). These critical care nurses revealed profiles that, whilst not in crisis, fell short of the ideal high compassion satisfaction and moderate/low fatigue. More recent tenure flags those potentially at higher risk of compassion fatigue, whilst the better scores associated with postgraduate education and from one site need further exploration. Further research should develop understanding and interventions to enhance compassion satisfaction and support retention of this crucial nursing workforce.

This study experimentally examined the impact of exposure to fitspiration images and self-compassion quotes on social media on young women's body satisfaction, body appreciation, self-compassion, and negative mood. Female undergraduate students (N=160) were randomly assigned to view either Instagram images of fitspiration, self-compassion quotes, a combination of both, or appearance-neutral images. Results showed no differences between viewing fitspiration images compared to viewing neutral images, except for poorer self-compassion among those who viewed fitspiration images. However, women who viewed self-compassion quotes showed greater body satisfaction, body appreciation, self-compassion, and reduced negative mood compared to women who viewed neutral images. Further, viewing a combination of fitspiration images and self-compassion quotes led to positive outcomes compared to viewing only fitspiration images. Trait levels of thin-ideal internalisation moderated some effects. The findings suggest that self-compassion might offer a novel avenue for attenuating the negative impact of social media on women's body satisfaction. Copyright © 2017 Elsevier Ltd.

Witness to suffering: mindfulness and compassion fatigue among traumatic bereavement volunteers and professionals.

PubMed

Thieleman, Kara; Cacciatore, Joanne

2014-01-01

This study used a survey to investigate the relationship between mindfulness and compassion fatigue and compassion satisfaction among 41 volunteers and professionals at an agency serving the traumatically bereaved. Compassion fatigue comprises two aspects: secondary traumatic stress and burnout. Because prior research suggests that compassion satisfaction may protect against compassion fatigue, the authors hypothesized that (a) mindfulness would be positively correlated with compassion satisfaction, (b) mindfulness would be inversely correlated with compassion fatigue, and (c) there would be differences between respondents with a personal history of traumatic bereavement and those with no such history. Correlation analyses supported the first two hypotheses; an independent means t test did not provide evidence for the latter hypothesis, although the number ofnontraumatically bereaved respondents was small. Overall, this sample showed surprisingly high levels of compassion satisfaction and low levels of compassion fatigue, even among respondents thought to be at higher risk of problems due to personal trauma. Implications of these findings are particularly relevant for social workers and other professionals employed in positions in which they encounter trauma and high emotional stress.

LHCb RICH Upgrade: an overview of the photon detector and electronic system

NASA Astrophysics Data System (ADS)

Cassina, L.

2016-01-01

The LHCb experiment is one of the four large detectors operating at the LHC at CERN and it is mainly devoted to CP violation measurements and to the search for new physics in rare decays of beauty and charm hadrons. The data from the two Ring Image Cherenkov (RICH-1 and RICH-2) detectors are essential to identify particles in a wide momentum range. From 2019 onwards 14 TeV collisions with luminosities reaching up to 2 × 1033 cm-2s-1 with 25 ns bunch spacing are planned, with the goal of collecting 5 fb-1 of data per year. In order to avoid degradation of the PID performance at such high rate (40 MHz), the RICH detector has to be upgraded. New photodetectors (Multi-anode photomultiplier tubes, MaPMTs) have been chosen and will be read out using an 8-channel chip, named CLARO, designed to sustain a photon counting rate up to 40 MHz, while minimizing the power consumption and the cross-talk. A 128-bit digital register allows selection of thresholds and attenuation values and provides features useful for testing and debugging. Photosensors and electronics are arranged in basic units, the first prototypes of which have been tested in charged particle beams in autumn 2014. An overview of the CLARO features and of the readout electronics is presented.

Compassion fatigue, trigger situations, and coping strategies were investigated in hospital and home care nurses. The Professional Quality of Life Scale measured compassion fatigue, compassion satisfaction, and burnout. Narrative questions elicited trigger situations and coping strategies. Compassion fatigue scores were significantly different between nurses who worked 8- or 12-hour shifts. Fifteen percent of the participants had scores indicating risk of the compassion fatigue. There were significant differences in compassion satisfaction, depending on the unit worked and time as a nurse. The most common category of trigger situations was caring for the patient. Work-related and personal coping strategies were identified. Copyright © 2010 Elsevier Inc. All rights reserved.

Development of an iterative reconstruction method to overcome 2D detector low resolution limitations in MLC leaf position error detection for 3D dose verification in IMRT.

The objective of this study was to introduce a new iterative method to reconstruct multi leaf collimator (MLC) positions based on low resolution ionization detector array measurements and to evaluate its error detection performance. The iterative reconstruction method consists of a fluence model, a detector model and an optimizer. Expected detector response was calculated using a radiotherapy treatment plan in combination with the fluence model and detector model. MLC leaf positions were reconstructed by minimizing differences between expected and measured detector response. The iterative reconstruction method was evaluated for an Elekta SLi with 10.0 mm MLC leafs in combination with the COMPASS system and the MatriXX Evolution (IBA Dosimetry) detector with a spacing of 7.62 mm. The detector was positioned in such a way that each leaf pair of the MLC was aligned with one row of ionization chambers. Known leaf displacements were introduced in various field geometries ranging from  -10.0 mm to 10.0 mm. Error detection performance was tested for MLC leaf position dependency relative to the detector position, gantry angle dependency, monitor unit dependency, and for ten clinical intensity modulated radiotherapy (IMRT) treatment beams. For one clinical head and neck IMRT treatment beam, influence of the iterative reconstruction method on existing 3D dose reconstruction artifacts was evaluated. The described iterative reconstruction method was capable of individual MLC leaf position reconstruction with millimeter accuracy, independent of the relative detector position within the range of clinically applied MU's for IMRT. Dose reconstruction artifacts in a clinical IMRT treatment beam were considerably reduced as compared to the current dose verification procedure. The iterative reconstruction method allows high accuracy 3D dose verification by including actual MLC leaf positions reconstructed from low resolution 2D measurements.

The current study sought to conduct a preliminary investigation of the effectiveness and feasibility of a novel, self-guided online self-compassion training for reducing psychological distress and increasing self-compassion and happiness among psychology trainees. A 6-week online self-compassion cultivation program was developed and delivered to Australian psychology trainees (n = 37), and a pre-experimental repeated-measures design was used to collect change data on self-compassion, happiness, perceived stress, emotion regulation difficulties as well as symptoms of depression, anxiety, and stress. Participants reported significant increases in self-compassion and happiness and significant decreases in depression, stress, and emotion regulation difficulties between pretest and posttest, with the majority of changes maintained at 3-month follow up.  This study provides preliminary evidence supporting the effectiveness and acceptability of online self-compassion training as a positive, integrated, and meaningful way of reducing distress and promoting self-compassion and happiness among trainee psychologists. © 2016 Wiley Periodicals, Inc.

Self-Compassion and the Self-Regulation of Exercise: Reactions to Recalled Exercise Setbacks.

PubMed

Semenchuk, Brittany N; Strachan, Shaelyn M; Fortier, Michelle

2018-02-01

Self-compassion facilitates health behavior self-regulation; few studies have examined self-compassion and exercise. This online, cross-sectional study investigated self-compassion's relationship with exercise self-regulation of an exercise setback. Adults (N = 105) who had experienced an exercise setback within the last 6 months completed baseline measures, recalled an exercise setback, and completed questionnaires assessing self-regulation in this context. Self-compassion associated with self-determined motivations and exercise goal reengagement, and negatively related to extrinsic motivations, state rumination, and negative affect. Self-compassion predicted unique variance, beyond self-esteem, in exercise goal reengagement, external regulation, state rumination, and negative affect experienced after an exercise setback. Self-compassion and self-esteem had unique relationships with goal reengagement, state rumination, and situational motivation, while having a complementary relationship with negative affect. This research adds to the few studies that examine the role of self-compassion in exercise self-regulation by examining how self-compassion and self-esteem relate to reactions to a recalled exercise setback.

A New View on an Old Debate: Type of Cue-Conflict Manipulation and Availability of Stars Can Explain the Discrepancies between Cue-Calibration Experiments with Migratory Songbirds.

PubMed

Sjöberg, Sissel; Muheim, Rachel

2016-01-01

Migratory birds use multiple compass systems for orientation, including a magnetic, star and sun/polarized light compass. To keep these compasses in register, birds have to regularly update them with respect to a common reference. However, cue-conflict studies have revealed contradictory results on the compass hierarchy, favoring either celestial or magnetic compass cues as the primary calibration reference. Both the geomagnetic field and polarized light cues present at sunrise and sunset have been shown to play a role in compass cue integration, and evidence suggests that polarized light cues at sunrise and sunset may provide the primary calibration reference for the other compass systems. We tested whether migratory garden warblers recalibrated their compasses when they were exposed to the natural celestial cues at sunset in a shifted magnetic field, which are conditions that have been shown to be necessary for the use of a compass reference based on polarized light cues. We released the birds on the same evening under a starry sky and followed them by radio tracking. We found no evidence of compass recalibration, even though the birds had a full view of polarized light cues near the horizon at sunset during the cue-conflict exposure. Based on a meta-analysis of the available literature, we propose an extended unifying theory on compass cue hierarchy used by migratory birds to calibrate the different compasses. According to this scheme, birds recalibrate their magnetic compass by sunrise/sunset polarized light cues, provided they have access to the vertically aligned band of maximum polarization near the horizon and a view of landmarks. Once the stars appear in the sky, the birds then recalibrate the star compass with respect of the recalibrated magnetic compass. If sunrise and sunset information can be viewed from the same location, the birds average the information to get a true geographic reference. If polarized light information is not available near the horizon at sunrise or sunset, the birds temporarily transfer the previously calibrated magnetic compass information to the available celestial compasses. We conclude that the type of cue-conflict manipulation and the availability of stars can explain the discrepancies between studies.

Migratory birds use multiple compass systems for orientation, including a magnetic, star and sun/polarized light compass. To keep these compasses in register, birds have to regularly update them with respect to a common reference. However, cue-conflict studies have revealed contradictory results on the compass hierarchy, favoring either celestial or magnetic compass cues as the primary calibration reference. Both the geomagnetic field and polarized light cues present at sunrise and sunset have been shown to play a role in compass cue integration, and evidence suggests that polarized light cues at sunrise and sunset may provide the primary calibration reference for the other compass systems. We tested whether migratory garden warblers recalibrated their compasses when they were exposed to the natural celestial cues at sunset in a shifted magnetic field, which are conditions that have been shown to be necessary for the use of a compass reference based on polarized light cues.

In its latest Long Range Plan for Nuclear Science Research in the U.S., the Nuclear Science Advisory Committee to the Department of Energy recommended that in regards to new nuclear-physics facilities, the construction of an Electron Ion Collider (EIC) be of the highest priority after the completion of the Facility for Rare Isotope Beams. In order to carry out key aspects of the scientific program of the EIC, the EIC central detector must be capable of hadron particle identification (PID) over a broad momentum range of up to 50 GeV/c. The goal of the EIC-PID consortium is to develop an integrated program for PID at EIC, which employs several different technologies for imaging Cherenkov detectors. Here we discuss the conceptual designs and the expected PID performance of two of these detectors, as well as the newest results of gain evaluation studies of photon sensors that are good candidates to read out these detectors. Development of a gas-aerogel dual-radiator Ring Imaging Cherenkov (dRICH) detector with outward focusing mirrors is being pursued for the hadron endcap. Simulations demonstrate that the dRICH can provide a continuous >= 3σ π /K/p separation from 2.5 GeV/c to 50 GeV/c. A modular aerogel Ring Imaging Cherenkov (mRICH) detector with a Fresnel lens as a focusing element is being pursued for the electron endcap. The design provides for hadron identification over a momentum range of 3 GeV/c-10 GeV/c. The working principle of the mRICH design has been proven in a beam test with a first prototype. The location of the sensor readout planes of the Cherenkov detectors in the magnetic field of the central-detector solenoid, which is expected to be within 1.5 T-3 T, makes is necessary to evaluate the limit of the acceptable performance of commercially available photosensors, such as microchannel-plate photomultipliers (MCP PMTs). Here we present the results of gain evaluation of multi-anode MCP PMTs with a pore size of 10 μm. Overall, our preliminary results suggest that the 10-μm pore-size sensors can be operated in a magnetic field with magnitude up to Bmax of 2 T. The value of Bmax depends on the relative orientation between the sensor and the field.

A magnetic compass aids monarch butterfly migration

PubMed Central

Guerra, Patrick A; Gegear, Robert J; Reppert, Steven M

2014-01-01

Convincing evidence that migrant monarch butterflies (Danaus plexippus) use a magnetic compass to aid their fall migration has been lacking from the spectacular navigational capabilities of this species. Here we use flight simulator studies to show that migrants indeed possess an inclination magnetic compass to help direct their flight equatorward in the fall. The use of this inclination compass is light-dependent utilizing ultraviolet-A/blue light between 380 and 420 nm. Notably, the significance of light <420 nm for inclination compass function was not considered in previous monarch studies. The antennae are important for the inclination compass because they appear to contain light-sensitive magnetosensors. For migratory monarchs, the inclination compass may serve as an important orientation mechanism when directional daylight cues are unavailable and may also augment time-compensated sun compass orientation for appropriate directionality throughout the migration.

The influence of self-compassion on emotional well-being among early and older adolescent males and females

PubMed Central

Bluth, Karen; Blanton, Priscilla W.

2014-01-01

Self-compassion has been associated with well-being in adult samples, but has rarely been assessed in adolescents. In this study, 90 students ages 11–18 completed an online survey assessing self-compassion, life satisfaction, perceived stress and positive and negative affect. Findings indicated that older female adolescents had lower self-compassion than either older male adolescents or early adolescents of either gender, and self-compassion was associated significantly with all dimensions of emotional well-being with the exception of positive affect. Additionally, phase of adolescence, but not gender, was found to moderate the relationship between self-compassion and dimensions of well-being; for older adolescents, the inverse relationship between self-compassion and negative affect was stronger. Lastly, the influence of the various components of self-compassion was investigated and discussed. PMID:25750655

The depth of the honeybee's backup sun-compass systems.

Honeybees have at least three compass mechanisms: a magnetic compass; a celestial or sun compass, based on the daily rotation of the sun and sun-linked skylight patterns; and a backup celestial compass based on a memory of the sun's movements over time in relation to the landscape. The interactions of these compass systems have yet to be fully elucidated, but the celestial compass is primary in most contexts, the magnetic compass is a backup in certain contexts, and the bees' memory of the sun's course in relation to the landscape is a backup system for cloudy days. Here we ask whether bees have any further compass systems, for example a memory of the sun's movements over time in relation to the magnetic field. To test this, we challenged bees to locate the sun when their known celestial compass systems were unavailable, that is, under overcast skies in unfamiliar landscapes. We measured the bees' knowledge of the sun's location by observing their waggle dances, by which foragers indicate the directions toward food sources in relation to the sun's compass bearing. We found that bees have no celestial compass systems beyond those already known: under overcast skies in unfamiliar landscapes, bees attempt to use their landscape-based backup system to locate the sun, matching the landscapes or skylines at the test sites with those at their natal sites as best they can, even if the matches are poor and yield weak or inconsistent orientation.

Compassion for others, self-compassion, quality of life and mental well-being measures and their association with compassion fatigue and burnout in student midwives: A quantitative survey.

compassion fatigue and burnout can impact on the performance of midwives, with this quantitative paper exploring the relationship between self-compassion, burnout, compassion fatigue, self-judgement, self-kindness, compassion for others, professional quality of life and well-being of student midwives. a quantitative survey measured relationships using questionnaires: (1) Professional Quality of Life Scale; (2) Self-Compassion Scale; (3) Short Warwick and Edinburgh Mental Well-being Scale; (4) Compassion For Others Scale. a purposive and convenience sample of student midwives (n=103) studying at university participated in the study. just over half of the sample reported above average scores for burnout. The results indicate that student midwives who report higher scores on the self-judgement sub-scale are less compassionate towards both themselves and others, have reduced well-being, and report greater burnout and compassion fatigue. Student midwives who report high on measures of self-compassion and well-being report less compassion fatigue and burnout. student midwives may find benefit from 'being kinder to self' in times of suffering, which could potentially help them to prepare for the emotional demands of practice and study. developing, creating and cultivating environments that foster compassionate care for self and others may play a significant role in helping midwives face the rigours of education and clinical practice during their degree programme.

Voloshin, Andrew; Benmokhtar, Fatiha; Lendacky, Andrew; Goodwill, Justin

2017-01-01

The CLAS12 detector at Thomas Jefferson National Accelerator Facility (TJNAF) is undergoing an upgrade. One of the improvements is the addition of a Ring Imaging Cherenkov (RICH) detector to improve particle identification in the 3-8 GeV/c momentum range. Approximately 400 multi anode photomultiplier tubes (MAPMTs) are going to be used to detect Cherenkov Radiation in the single photoelectron spectra (SPS). Software development for slow control as well as online monitoring is under development. I will be presenting my work on the development of a java based programs for a monitor and explain its interaction with a Mysql database where the MAPMTs information is stored as well as the techniques used to visualize Cherenkov rings.

A GPU-based low level (L0) trigger is currently integrated in the experimental setup of the RICH detector of the NA62 experiment to assess the feasibility of building more refined physics-related trigger primitives and thus improve the trigger discriminating power. To ensure the real-time operation of the system, a dedicated data transport mechanism has been implemented: an FPGA-based Network Interface Card (NaNet-10) receives data from detectors and forwards them with low, predictable latency to the memory of the GPU performing the trigger algorithms. Results of the ring-shaped hit patterns reconstruction will be reported and discussed.

For the Belle II spectrometer a proximity focusing RICH counter with an aerogel radiator (ARICH) will be employed as a PID system in the forward end-cap region of the spectrometer. The detector will provide about 4σ separation of pions and kaons up to momenta of 3.5 GeV/c, at the kinematic limits of the experiment. We present the up-to-date status of the ARICH simulation and reconstruction software, focusing on the recent improvements of the reconstruction algorithms and detector description in the Geant4 simulation. In addition, as a demonstration of detector readout software functionality we show the first cosmic ray Cherenkov rings observed in the ARICH.

Modeling the Effects of Mirror Misalignment in a Ring Imaging Cherenkov Detector

2012-03-01

The Very High Momentum Particle Identification Detector (VHMPID) has been proposed for the ALICE experiment at the Large Hadron Collider (LHC). This detector upgrade is considered necessary to study jet-matter interaction at high energies. The VHMPID identifies charged hadrons in the 5 GeV/c to 25 GeV/c momentum range. The Cherenkov photons emitted in the VHMPID radiator are collected by spherical mirrors and focused onto a photo-detector plane forming a ring image. The radius of this ring is related to the Cherenkov angle, this information coupled with the particle momentum allows the particle identification. A major issue in the RICH detector is that environmental conditions can cause movements in mirror position. In addition, chromatic dispersion causes the refractive index to shift, altering the Cherenkov angle. We are modeling a twelve mirror RICH detector taking into account the effects of mirror misalignment and chromatic dispersion using a commercial optical software package. This will include quantifying the effects of both rotational and translational mirror misalignment for the initial assembly of the module and later on particle identification.

To investigate the effects of the practice of yoga in combination with compassion meditation on the quality of life, attention, vitality and self-compassion of family caregivers of patients with Alzheimer's disease. A total of 46 volunteers were randomly allocated to two groups, the yoga and compassion meditation program group (n = 25), and the control group (CG) that received no treatment (n = 21). The program lasted 8 weeks, and comprised three yoga and meditation practices per week, with each session lasting 1 h and 15 min. Quality of life, attention, vitality, and self-compassion scores were measured pre- and postintervention. The yoga and compassion meditation program group showed statistically significant improvements (P < 0.05) on quality of life, attention, vitality and self-compassion scores as compared with the control group, which showed no statistical significant differences at the postintervention time-point. The findings of the present study suggest that an 8-week yoga and compassion meditation program can improve the quality of life, vitality, attention, and self-compassion of family caregivers of Alzheimer's disease patients.

Compassion fatigue is a state of detachment and isolation experienced when healthcare providers repeatedly engage with patients in distress. Compassion fatigue can hinder empathy and cause extreme tension. Prior research suggests 73.8 % of genetic counselors are at moderate to high risk for compassion fatigue and approximately 1 in 4 have considered leaving the field as a result Injeyan et al. (Journal of Genetic Counseling, 20, 526-540, 2011). Empirical data to establish a reliable profile of genetic counselors at risk for compassion fatigue are limited. Thus the purpose of this study was to establish a profile by assessing relationships between state and trait anxiety, burnout, compassion satisfaction, selected demographics and compassion fatigue risk in practicing genetic counselors. Practicing genetic counselors (n = 402) completed an anonymous, online survey containing demographic questions, the State-Trait Anxiety Inventory, and the Professional Quality of Life scale. Multiple regression analysis yielded four significant predictors which increase compassion fatigue risk (accounting for 48 % of the variance): higher levels of trait anxiety, burnout, and compassion satisfaction, and ethnicity other than Caucasian. Additional findings, study limitations, practice implications, and research recommendations are provided.

Compassion Fatigue and Compassion Satisfaction in Hospice Social Work.

Pelon, Sally B

2017-01-01

As part of the interprofessional team of hospice caregivers, social workers are exposed to multiple stressors, both in their work with dying patients and their families and in functioning as professionals within rapidly changing health care organizations. Ongoing exposure to such stressors prompts concern about the emotional and psychological effect working with people who are dying may have on those who do it. Further, an understanding is needed regarding how hospice social workers interpret the costs and benefits of their work and how they cope with the dying and loss that pervade their everyday work lives. This descriptive, cross-sectional study explored the prevalence of compassion fatigue among hospice social workers and considered compassion satisfaction as a means to mitigate compassion fatigue. Fifty-five hospice social workers from 34 hospice organizations in Michigan completed an online survey. Results suggested that compassion fatigue is indeed a concern among hospice social workers. In addition, compassion fatigue and compassion satisfaction were found to be negatively correlated and suggested that compassion satisfaction may act as a protective mechanism against compassion fatigue. These results may provide insight regarding how best to mitigate this professional hazard in end-of-life social work.

Compassion fatigue among pediatric healthcare providers.

Compassion fatigue is a term used to describe the unique stressors affecting people in caregiving professions. For nurses and other direct care providers, the impact of compassion fatigue may result in stress-related symptoms, job dissatisfaction, decreased productivity, decreased patient satisfaction scores, safety issues, and job turnover. Those who care for seriously ill children and their families are at increased risk for compassion fatigue. Constant exposure to children who are suffering, in combination with work place stressors and personal issues, may contribute to the development of compassion fatigue. The Professional Quality of Life Scale Version 5 was used to determine the risk for compassion fatigue among 296 direct care providers at St. Louis Children's Hospital. Compassion satisfaction, burnout, and secondary traumatic stress scores did not differ by age, work category, level of education, or work experience. There were, however, significant differences in scores as a function of nursing unit. Nurses who work in the pediatric intensive care unit reported lower compassion satisfaction scores, and higher burnout and secondary traumatic stress scores. Results demonstrated the risk for compassion fatigue and provided data necessary to support development of a compassion fatigue program for direct care providers.

The CAPRICE98 balloon-borne experiment was flown on 28-29 May 1998 from Fort Sumner, New Mexico, USA. The detector configuration included the NMSUWiZard/CAPRICE magnetic spectrometer equipped with a gas RICH detector, a silicon-tungsten calorimeter and a timeof-flight system. By combining the RICH and the spectrometer information it was possible to separate 2 H from 1 H in the rigidity range from 29 to 40 GV. We describe the method of analysis and we report results on the 2 H abundance.

2017-05-01

The Alpha Magnetic Spectrometer (AMS-02), which is installed on the International Space Station (ISS), has been collecting data successfully since May 2011. The main goals of AMS-02 are the search for cosmic anti-matter, dark matter and the precise measurement of the relative abundance of elements and isotopes in galactic cosmic rays. In order to identify particle properties, AMS-02 includes several specialized sub-detectors. Among these, the AMS-02 Ring Imaging Cherenkov detector (RICH) is designed to provide a very precise measurement of the velocity and electric charge of particles. We describe a method to reject the dominant electron background in antiproton identification with the use of the AMS-02 RICH detector as a veto for rigidities below 3 GV. A ray tracing integration method is used to maximize the statistics of p¯ with the lowest possible e- background, providing 4 times rejection power gain for e- background with respect to only 3% of p¯ signal efficiency loss. By using the collected cosmic-ray data, e- contamination can be well suppressed within 3% with β ≈ 1, while keeping 76% efficiency for p¯ below the threshold.

2005-01-01

Participants at a June 2002 conference about the September 11th attacks were tested for compassion fatigue, compassion satisfaction, and burnout. The sample consisted of 343 clergy, including 97 chaplains. A total of 149 (43.4%) of the participants had responded as disaster-relief workers following the September 11th attacks. The number of hours clergy worked with trauma victims each week was directly related to compassion fatigue among responders and non-responders. Compassion fatigue also was positively related to the number of days that responders worked at Ground Zero, while disaster-relief work with the American Red Cross reduced compassion fatigue and burnout. Clinical Pastoral Education tended to decrease compassion fatigue and burnout and increase compassion satisfaction in both responders and non-responders. Burnout was inversely related to age in both groups.

To examine the experiences of compassion fatigue, burnout, and compassion satisfaction among oncology nurses in the United States and Canada. 
. Quantitative, descriptive, nonexperimental.
. Online survey with members from the Canadian Association of Nursing Oncology and the Oncology Nursing Society.
. 486 American and 63 Canadian practicing oncology nurses.
. The Professional Quality of Life (ProQOL) scale, version 5, and modified Abendroth Demographic Questionnaire were administered through FluidSurveys™, an online data collection instrument. Chi-square tests of independence were used to investigate associations between demographic characteristics, health, personal stressors, and work-related characteristics to experiences of compassion fatigue, burnout, and compassion satisfaction. Compassion fatigue was measured using the subscales of secondary traumatic stress and burnout. 
. Compassion fatigue, burnout, and compassion satisfaction.
. Demographic characteristics were similar in American and Canadian participants, and both cohorts reported comparable levels of compassion fatigue, burnout, and compassion satisfaction. Perception of team cohesiveness within the workplace environment was found to be significant for both groups, as indicated by significant relationships in all three subscales of secondary traumatic stress, burnout, and compassion satisfaction in the ProQOL.
. Healthy and supportive work environments are imperative to nurses' health, well-being, and satisfaction. Improvements in the workplace can help prevent negative sequelae, as well as improve health outcomes for patients and nurses, decrease nurse turnover, and reduce healthcare expenditures. 
. Findings can be used to implement institutional changes, such as creating policies and guidelines for the development of preventive interventions and psychosocial support for nurses.

To test a hypothetical path model evaluating the influence of type D personality on job stress and job satisfaction and to identify the mediating effects of compassion fatigue, burnout, and compassion satisfaction among clinical nurses in South Korea. Personalities susceptible to stress, compassion fatigue, and burnout in clinical nurses have negative effects on the job stress and job satisfaction. A correlational, cross-sectional design was used. A convenience sample of 875 clinical nurses was recruited between December 2014 - February 2015. The structured questionnaires included the Type D personality scale-14, Professional Quality of Life, job stress, job satisfaction, and general characteristics. To test the hypothetical path model, we performed a path analysis by using the AMOS 18·0 program. Based on the path model, type D personality was significantly associated with compassion fatigue, burnout, and compassion satisfaction in our study subjects. Type D personality was significantly associated with job stress and job satisfaction via the effect of burnout, compassion satisfaction, and job stress. Since type D personality is associated with job stress and job satisfaction, identifying personalities vulnerable to stress would help to address job stress and to enhance job satisfaction when nurses have a high level of compassion fatigue and burnout and a low level of compassion satisfaction. The development of interventions that can reduce negative affect and social inhibition of nurses with type D personality and investigation of methods to decrease their compassion fatigue and burnout and to increase compassion satisfaction should be encouraged. © 2016 John Wiley & Sons Ltd.

To be kind or not to be kind: The moderating role of self-compassion in the relationship between general resourcefulness and academic self-regulation.

PubMed

Martin, Rebecca D; Kennett, Deborah J

2017-11-22

We investigated whether the relationship between students' general resourcefulness and academic self-regulation changes as a function of self-compassion. A predominantly female sample of 196 undergraduates completed inventories assessing these and other measures. The significant moderating effect of self-compassion revealed that the positive relationship between general resourcefulness and academic self-regulation was stronger for participants scoring low in self-compassion than high in self-compassion. For those low in self-compassion, scoring low in general resourcefulness was associated with the lowest academic self-regulation, whereas scoring high in general resourcefulness was associated with the greatest academic self-regulation. The positive relationship between general and academic self-regulation was attenuated for participants high in self-compassion, with predicted scores for academic self-regulation falling in between the two values described for the low self-compassion function. Implications of the findings are discussed, including the potential value of incorporating self-compassion training alongside programs aimed at increasing general resourcefulness and academic self-regulation.

Self-compassion versus global self-esteem: two different ways of relating to oneself.

PubMed

Neff, Kristin D; Vonk, Roos

2009-02-01

This research examined self-compassion and self-esteem as they relate to various aspects of psychological functioning. Self-compassion entails treating oneself with kindness, recognizing one's shared humanity, and being mindful when considering negative aspects of oneself. Study 1 (N=2,187) compared self-compassion and global self-esteem as they relate to ego-focused reactivity. It was found that self-compassion predicted more stable feelings of self-worth than self-esteem and was less contingent on particular outcomes. Self-compassion also had a stronger negative association with social comparison, public self-consciousness, self-rumination, anger, and need for cognitive closure. Self-esteem (but not self-compassion) was positively associated with narcissism. Study 2 (N=165) compared global self-esteem and self-compassion with regard to positive mood states. It was found that the two constructs were statistically equivalent predictors of happiness, optimism, and positive affect. Results from these two studies suggest that self-compassion may be a useful alternative to global self-esteem when considering what constitutes a healthy self-stance.

To this purpose, direct GPU communication with a custom FPGA-based board has been used to reduce the data transmission latency. The GPU-based trigger system is currently integrated in the experimental setup of the RICH detector of the NA62 experiment, in order to reconstruct ring-shaped hit patterns. The ring-fitting algorithm running on GPU is fed with raw RICH data only, with no information coming from other detectors, and is able to provide more complex trigger primitives with respect to the simple photodetector hit multiplicity, resulting in a higher selection efficiency. The performance of the system for multi-ring Cherenkov online reconstruction obtained during the NA62 physics run is presented.

Compassion fatigue in pediatric palliative care providers.

PubMed

Rourke, Mary T

2007-10-01

The experience of compassion fatigue is an expected and common response to the professional task of routinely caring for children at the end of life. Symptoms of compassion fatigue often mimic trauma reactions. Implementing strategies that span personal, professional, and organizational domains can help protect health care providers from the damaging effects of compassion fatigue. Providing pediatric palliative care within a constructive and supportive team can help caregivers deal with the relational challenges of compassion fatigue. Finally, any consideration of the toll of providing pediatric palliative care must be balanced with a consideration of the parallel experience of compassion satisfaction.

To identify the mechanisms involved in the association between self-compassion and depression, we examined whether adaptive emotion regulation would mediate the relationship between self-compassion and depression in individuals with unipolar depression. Furthermore, we explored which specific emotion regulation skills would be most important in this relationship. Sixty-nine individuals with unipolar depression were assessed with the Self-Compassion Scale and the Emotion Regulation Skills Questionnaire at baseline and with the Beck Depression Inventory-II 1 week later. The results showed that successful application of emotion regulation skills mediates the association between self-compassion and depression. Among eight specific emotion regulation skills, only the ability to tolerate negative emotions was identified as a significant mediator in the self-compassion-depression relationship. These findings provide preliminary evidence that systematically fostering self-compassion might help depressed individuals cope with their symptoms by enhancing their abilities to tolerate undesired emotions. Systematically fostering self-compassion through specific compassion-focused interventions might facilitate a reduction in depressive symptoms by improving the person's emotion regulation abilities, especially by improving his or her ability to tolerate negative emotions. Hence, compassion-focused interventions might be particularly promising in depressed patients with a tendency to avoid negative emotions and deficits in tolerating them. © 2016 The British Psychological Society.

Women's empowerment: Finding strength in self-compassion.

Stevenson, Olivia; Allen, Ashley Batts

2017-03-01

Empowerment is often a desired outcome for health programs; however, it is rarely evaluated. One way to increase empowerment may be through self-compassion. The authors of the current study aimed to determine whether self-compassion and empowerment were positively related. Two hundred and five women (ages 18 to 48 years) were recruited from a pool of undergraduate students at a university in the southeastern United States in the summer/fall of 2012. Participants completed the study using Qualtrics, an online survey system. Participants wrote about a fight in a romantic relationship and were randomly assigned to write about the fight either self-compassionately or generally. Empowerment and perceptions of the fight were assessed as dependent measures. Hierarchical regression analyses investigated the relation of self-compassion, manipulated self-compassion, and their interaction with empowerment. A significant positive relationship was found between self-compassion and empowerment. However, manipulated self-compassion was not significantly related to empowerment. These findings suggested that self-compassion and empowerment were strongly related, but using a short-term self-compassion intervention may not be strong enough to influence empowerment. Empowerment-based practitioners may find empowerment increases more easily in women who are self-compassionate. If self-compassion is incorporated into empowerment settings, a long-term intervention may be necessary.

Caregiving results in both positive and negative outcomes for caregivers. The purpose of this study was to examine compassion fatigue and compassion satisfaction in family caregivers. Using a cross sectional descriptive survey design with a convenience sample, 168 family caregivers of individuals with chronic illness completed a web-based survey. Measures included a demographic questionnaire, Caregiver Burden Interview, Brief COPE inventory and Professional Quality of Life (ProQOL). The majority of participants (71%) reported high levels of caregiver burden, moderate to low levels of the compassion fatigue concepts of burnout (59.5%) and secondary traumatic stress (STS) (50%), and moderate levels of compassion satisfaction (82.7%). Regression analyses showed that caregiver burden, time caregiving, coping, social support, and caregiving demands explained a total variance of 57.1%, F(11,119) = 14.398, p < .00 in burnout and a total variance of 56%, F(11, 119) = 13.64, p < .00 in STS. Specifically, behavioral disengagement is a predicator that may indicate early compassion fatigue. Findings suggest that despite high caregiver burden and moderate compassion fatigue, family caregivers are able to provide care and find satisfaction in the role. This study supports the use of compassion fatigue and compassion satisfaction as alternative or additional outcomes to consider in future research.

[Development and Application of an Overcoming Compassion Fatigue Program for Emergency Nurses].

This study was conducted to develop a program to help emergency nurses overcome compassion fatigue, and to analyze the effects of the program. A nonequivalent control group pretest-posttest design was used. There were 14 participants in the experimental group and 18 subjects in the control group. The program was comprised of five, weekly 80-minute sessions including understanding and assessment of compassion fatigue, enhancing positive affect, balancing work-life, planning self care, training in relaxation techniques and cognitive restructuring, and getting social support. Research variables were ego-resiliency, compassion satisfaction and compassion fatigue of the ProQOL 5, and salivary cortisol. Data were analyzed using Chi-square test, independent t-test, and paired t-test. The first hypothesis, "There will be a difference in scores for ego resiliency between the experimental group and the control group". was not supported. The second hypothesis, "There will be a difference in scores for compassion satisfaction between the experimental group and the control group" was supported (t=2.15, p=.046). The third hypothesis, "There will be a difference in scores for compassion fatigue between the experimental group and the control group" was not supported. The first program for emergency nurses to overcome compassion fatigue in Korea was effective in increasing emergency nurses' compassion satisfaction and decreasing salivary cortisol level in the experimental group. Therefore, this program for overcoming compassion fatigue is useful to increase emergency nurses' compassion satisfaction. However replication studies of short-term intensive program reflecting emergency nurses' opinion are needed.

Barriers to Medical Compassion as a Function of Experience and Specialization: Psychiatry, Pediatrics, Internal Medicine, Surgery, and General Practice.

PubMed

Fernando, Antonio T; Consedine, Nathan S

2017-06-01

Compassion is an expectation of patients, regulatory bodies, and physicians themselves. Most research has, however, studied compassion fatigue rather than compassion itself and has concentrated on the role of the physician. The Transactional Model of Physician Compassion suggests that physician, patient, external environment, and clinical factors are all relevant. Because these factors vary both across different specialities and among physicians with differing degrees of experience, barriers to compassion are also likely to vary. We describe barriers to physician compassion as a function of specialization (psychiatry, general practice, surgery, internal medicine, and pediatrics) and physician experience. We used a cross-sectional study using demographic data, specialization, practice parameters, and the Barriers to Physician Compassion Questionnaire. Nonrandom convenience sampling was used to recruit 580 doctors, of whom 444 belonged to the targeted speciality groups. The sample was characterized before conducting a factorial Multivariate Analysis of Covariance and further post hoc analyses. A 5 (speciality grouping) × 2 (more vs. less physician experience) Multivariate Analysis of Covariance showed that the barriers varied as a function of both speciality and experience. In general, psychiatrists reported lower barriers, whereas general practitioners and internal medicine specialists generally reported greater barriers. Barriers were generally greater among less experienced doctors. Documenting and investigating barriers to compassion in different speciality groups have the potential to broaden current foci beyond the physician and inform interventions aimed at enhancing medical compassion. In addition, certain aspects of the training or practice of psychiatry that enhance compassion may mitigate barriers to compassion in other specialities.

Decay properties of neutron rich isotopes, such as half-lives and β-delayed neutron emission probabilities, are an important input for astrophysical models of the r-process. A new generation of fragmentation beam facilities has made it possible to access large regions of the nuclear chart that are close to the path of the r-process for some astrophysical models. The Advanced Implantation Detector Array (AIDA) is a segmented active-stopper detector designed for decay experiments with fast ion beams, which was recently commissioned at the Radioactive Ion Beam Factory in RIKEN, Japan. In this presentation we describe the main characteristics of AIDA, and present preliminary results of the first experiments in the region of neutron-rich selenium isotopes and along the N=82 shell closure.

The cost of callousness: regulating compassion influences the moral self-concept.

PubMed

Cameron, C Daryl; Payne, B Keith

2012-03-01

It has often been argued that compassion is fundamental to morality. Yet people often suppress compassion for self-interested reasons. We provide evidence that suppressing compassion is not cost free, as it creates dissonance between a person's moral identity and his or her moral principles. We instructed separate groups of participants to regulate their compassion, regulate their feelings of distress, or freely experience emotions toward compassion--inducing images. Participants then reported how central morality was to their identities and how much they believed that moral rules should always be followed. Participants who regulated compassion-but not those who regulated distress or experienced emotions--showed a dissonance-based trade-off. If they reported higher levels of moral identity, they had a greater belief that moral rules could be broken. If they maintained their belief that moral rules should always be followed, they sacrificed their moral identity. Regulating compassion thus has a cost of its own: It forces trade-offs within a person's moral self-concept.

Self-compassion moderates body comparison and appearance self-worth's inverse relationships with body appreciation.

PubMed

Homan, Kristin J; Tylka, Tracy L

2015-09-01

Although research on positive body image has increased, little research has explored which variables protect body appreciation during body-related threats. Self-compassion may be one such variable. Individuals high in self-compassion are mindful, kind, and nurturing toward themselves during situations that threaten their adequacy, while recognizing that being imperfect is part of "being human." In this study, we investigated whether two body-related threats (i.e., body comparison and appearance contingent self-worth) were more weakly related to body appreciation when self-compassion was high among an online sample of 263 women (Mage=35.26, SD=12.42). Results indicated that self-compassion moderated the inverse relationships between body related threats and body appreciation. Specifically, when self-compassion was very high, body comparison and appearance contingent self-worth were unrelated to body appreciation. However, when self-compassion was low, these relationships were strong. Self-compassion, then, may help preserve women's body appreciation during body-related threats. Copyright © 2015 Elsevier Ltd.

Examining the Relationships Among Self-Compassion, Social Anxiety, and Post-Event Processing.

PubMed

Blackie, Rebecca A; Kocovski, Nancy L

2017-01-01

Post-event processing refers to negative and repetitive thinking following anxiety provoking social situations. Those who engage in post-event processing may lack self-compassion in relation to social situations. As such, the primary aim of this research was to evaluate whether those high in self-compassion are less likely to engage in post-event processing and the specific self-compassion domains that may be most protective. In study 1 ( N = 156 undergraduate students) and study 2 ( N = 150 individuals seeking help for social anxiety and shyness), participants completed a battery of questionnaires, recalled a social situation, and then rated state post-event processing. Self-compassion negatively correlated with post-event processing, with some differences depending on situation type. Even after controlling for self-esteem, self-compassion remained significantly correlated with state post-event processing. Given these findings, self-compassion may serve as a buffer against post-event processing. Future studies should experimentally examine whether increasing self-compassion leads to reduced post-event processing.

Definition of compassion-evoking images in a Mexican sample.

Mercadillo, Roberto E; Barrios, Fernando A; Díaz, José Luis

2007-10-01

To assemble a calibrated set of compassion-eliciting visual stimuli, 60 clinically healthy Mexican volunteers (36 women, 24 men; M age = 27.5 yr., SD = 2.4) assessed 84 pictures selected from the International Affective Picture System catalogue using the dimensions of Valence, Arousal, and Dominance included in the Self-assessment Manikin scale and an additional dimension of Compassion. Pictures showing suffering in social contexts and expressions of sadness elicited similar responses of compassion. The highest compassion response was reported for pictures showing illness and pain. Men and women differed in the intensity but not the quality of the compassionate responses. Compassion included attributes of negative emotions such as displeasure. The quality of the emotional response was not different from that previously reported for samples in the U.S.A., Spain, and Brazil. A set of 28 pictures was selected as high-compassion-evoking images and 28 as null-compassion controls suitable for studies designed to ascertain the neural substrates of this moral emotion.

Self-Compassion and Responses to Trauma: The Role of Emotion Regulation.

Scoglio, Arielle A J; Rudat, Deirdre A; Garvert, Donn; Jarmolowski, Maggie; Jackson, Christie; Herman, Judith L

2018-07-01

Emerging literature suggests that self-compassion may be an important concept for understanding recovery from the impact of trauma and posttraumatic stress disorder (PTSD). The present study explored the interconnection among self-compassion, resilience, emotion dysregulation, and PTSD symptom severity in a sample of treatment-seeking women with PTSD. We predicted that self-compassion would be negatively related to PTSD symptom severity and to emotion dysregulation, and positively related to resilience. The results supported our main hypotheses. In addition, emotion dysregulation mediated the relationship between PTSD symptom severity and self-compassion and affected the relationship between self-compassion and resilience. These findings corroborate previous research that points to the important role of self-compassion in mental health and in the aftermath of stressful life events. The present study expands this research by demonstrating that PTSD symptom severity is negatively related to self-compassion in a clinical population of women with experiences of severe and repeated interpersonal trauma.

Compassion fatigue describes a work-related stress response in healthcare providers that is considered a 'cost of caring' and a key contributor to the loss of compassion in healthcare. The purpose of this review was to critically examine the construct of compassion fatigue and to determine if it is an accurate descriptor of work-related stress in healthcare providers and a valid target variable for intervention. Meta-narrative review. PubMed, Medline, CINAHL, PsycINFO, and Web of Science databases, Google Scholar, the grey literature, and manual searches of bibliographies. Seminal articles and theoretical and empirical studies on compassion fatigue in the healthcare literature were identified and appraised for their validity and relevance to our review. Sources were mapped according to the following criteria: 1) definitions; 2) conceptual analyses; 3) signs and symptoms; 4) measures; 5) prevalence and associated risk factors; and 6) interventions. A narrative account of included studies that critically examines the concept of compassion fatigue in healthcare was employed, and recommendations for practice, policy and further research were made. 90 studies from the nursing literature and healthcare in general were included in the review. Findings emphasized that the physical, emotional, social and spiritual health of healthcare providers is impaired by cumulative stress related to their work, which can impact the delivery of healthcare services; however, the precise nature of compassion fatigue and that it is predicated on the provision of compassionate care is associated with significant limitations. The conceptualization of compassion fatigue was expropriated from crisis counseling and psychotherapy and focuses on limited facets of compassion. Empirical studies primarily measure compassion fatigue using the Professional Quality of Life Scale, which does not assess any of the elements of compassion. Reported risk factors for compassion fatigue include job-related factors, fewer healthcare qualifications and less years experience; however, there is no research demonstrating that exemplary compassionate carers are more susceptible to 'compassion fatigue'. In the last two decades, compassion fatigue has become a contemporary and iconic euphemism that should be critically reexamined in favour of a new discourse on healthcare provider work-related stress.

Today the proportion of acute patients entering the health care system through emergency departments continues to grow, the number of uninsured patients relying primarily on treatment in the emergency department is increasing, and patients' average acuities are rising. At the same time, support resources are constrained, while reimbursement and reputation depends increasingly on publicly available measures of patient satisfaction. It is important to understand the potential effect of these pressures on direct care staff. This study explores the prevalence of compassion satisfaction, burnout, and compassion fatigue among emergency nurses and nurses in other selected inpatient specialties. Emergency nurses and nurses from 3 other specialty units self-selected participation in a cross-sectional survey. Participants completed a sociodemographic profile and the Professional Quality of Life: Compassion Satisfaction and Fatigue Subscales, R-IV. Scale scores were summed for compassion satisfaction, burnout, and compassion fatigue for emergency nurses and compared with those of nurses in other specialties. Approximately 82% of emergency nurses had moderate to high levels of burnout, and nearly 86% had moderate to high levels of compassion fatigue. Differences between emergency nurses and those working in 3 other specialty areas, that is, oncology, nephrology, and intensive care, on the subscales for compassion satisfaction, burnout, or compassion fatigue did not reach the level of statistical significance. However, the scores of emergency nurses evidenced a risk for less compassion satisfaction, while intensive care nurses demonstrated a higher risk for burnout and oncology nurses reflected a risk for higher compassion fatigue. ED nurse managers, along with other nurse leaders, are faced with the competing demands of managing the satisfaction of patients, recruitment and retention of experienced nurses, and provision of quality and safe care customized to patients' needs and preferences. Understanding the concepts of compassion satisfaction, burnout, and compassion fatigue, recognizing the signs and symptoms, and identifying best practice interventions, will help nurses maintain caring attitudes with patients and contribute to patient satisfaction.

Adolescence is a challenging developmental period marked with declines in emotional well-being; however, self-compassion has been suggested as a protective factor. This cross-sectional survey study (N = 765, grades 7th to 12th; 53 % female; 4 % Hispanic ethnicity; 64 % White and 21 % Black) examined whether adolescents' self-compassion differed by age and gender, and secondly, whether its associations with emotional well-being (perceived stress, life satisfaction, distress intolerance, depressive symptoms, and anxiety) also differed by age and gender. The findings indicated that older females had the lowest self-compassion levels compared to younger females or all-age males. Self-compassion was associated with all emotional well-being measures, and gender and/or age moderated the associations with anxiety and depressive symptoms. Among older adolescents, self-compassion had a greater protective effect on anxiety for boys than for girls. Additionally, older adolescents with low and average self-compassion had greater levels of depressive symptoms than those with high self-compassion. These results may inform for whom and at what age self-compassion interventions may be implemented to protect adolescents from further declines in emotional well-being.

Compassion satisfaction, compassion fatigue, and burnout in a national sample of trauma treatment therapists.

For behavioral health professionals working with traumatized clients, continuous and prolonged exposure to the stress of working with the myriad of trauma-related stressors experienced by their clients can lead to various responses including burnout, compassion fatigue, and compassion satisfaction. The present study investigates the impact of using evidence-based practices on compassion fatigue, burnout, and compassion satisfaction in a random, national sample of self-identified trauma specialists (N=532). The 30-item Professional Quality of Life Scale (Stamm, 2005) and the 19-item Trauma Practices Questionnaire (Craig & Sprang, 2009) were included in a survey to licensed social workers and psychologists from professional membership rosters. Age and years of experience proved to be powerful predictors of only two of the three criterion variables, with younger professionals reporting higher levels of burnout and more experienced providers endorsing higher levels of compassion satisfaction. The utilization of evidence-based practices predicted statistically significant decreases in compassion fatigue and burnout, and increases in compassion satisfaction. The utility of these findings in understanding the process of trauma transmission between therapist and client as well as directions for future research are discussed.

Nurses experience an intrinsic sense of fulfillment derived from their work in caring for other people. There is a need to further investigate the concept of compassion satisfaction as it is experienced in the profession of nursing. The aim of this analysis is to provide clarity to the concept of compassion satisfaction in nursing. A search of social work and nursing literature was completed. The search terms "compassion satisfaction," "nursing," "social workers," "teachers," and "educators" were entered in various combinations to the CINAHL, Journals@Ovid, ProQuest Nursing & Allied Health Source, ProQuest Psychology Journals, PsychINFO, ERIC, and Education Full Text databases. A comprehensive review of the literature was completed to identify features of compassion satisfaction. Utilizing the Walker and Avant method, assumptions, antecedents, characteristics, and consequences of compassion satisfaction were identified. A conceptual model of compassion satisfaction was developed encompassing 7 antecedents, 11 characteristics, and 8 consequences. Further, a theoretical definition of compassion satisfaction in nursing was derived. There is a need to focus on the positive effects of caring. This concept analysis provides the initial step to strengthening the science related to compassion satisfaction in nursing and other helping professions. © 2017 Wiley Periodicals, Inc.

Compassion satisfaction, compassion fatigue, and critical incident stress management.

Wee, David; Myers, Diane

2003-01-01

This study examines the potential for compassion satisfaction, compassion fatigue, and burnout in a sample of persons attending a workshop on Prevention of Compassion Fatigue at an international conference of providers of Critical Incident Stress Management (CISM) services. In the study, more than half (58%) of the respondents reported experiencing psychological reactions after providing CISM services, including an array of behavioral, emotional, cognitive, and physical symptoms of psychological stress. Forty percent of respondents were found to have moderate, high, or extremely high risk for compassion fatigue. At the same time, 89% of respondents were found to have a good, high, or extremely high potential for compassion satisfaction, and 87% were found to be at extremely low risk for burnout. The results appear to indicate that, while the CISM practitioners recognize the stress associated with their work (as reflected in the reported symptoms), the work provides significant rewards (as measured by compassion satisfaction) that outweigh the stress and mitigate against burnout. Likewise, while 40% tested positive for compassion fatigue (or secondary traumatic stress) as a result of their empathy with CISM recipients, the rewards of the work again appear to mitigate the negative effects of the work. Implications for future research and practice are presented.

Compassion is considered the cornerstone of nursing practice. However, the recent failures in delivering high-quality compassionate nursing care in the UK's National Health Service have brought the topic of compassion to the attention of the public, service providers, policy makers and academics. The aim of this study was to explore the nurses' views and experiences of a number of compassion-related issues in nursing and describe similarities and differences at an international level as well as from the different nursing roles of the participating nurses. An exploratory, cross-sectional descriptive study, using the International Online Compassion Questionnaire. A total of 1323 nurses from 15 countries completed the questionnaire. The majority of participants (59.5%) defined compassion as "Deep awareness of the suffering of others and wish to alleviate it" but definitions of compassion varied by country. Of participants, 69.6% thought compassion was very important in nursing and more than half (59.6%) of them argued that compassion could be taught. However, only 26.8% reported that the correct amount and level of teaching is provided. The majority of the participants (82.6%) stated that their patients prefer knowledgeable nurses with good interpersonal skills. Only 4.3% noted that they are receiving compassion from their managers. A significant relationship was found between nurses' experiences of compassion and their views about teaching of compassion. Our study is unique in identifying the views and experiences of nurses from 15 different countries worldwide. The findings reveal that compassion is neither addressed adequately in nursing education nor supported in the practice environment by managers. Self-report bias was inherent to our survey study design. Furthermore, the individual cultural differences and similarities in the findings are difficult to extrapolate owing to the fact that our analysis was at country level, as well as at the level of the participating nurses. Understanding the influence of culture on nurses' views about compassion is critical in the current multicultural healthcare environment and merits further research. This will potentially drive changes in nursing education (ensuring that compassion is taught to nurses) and in the way healthcare leaders and managers foster a compassionate culture within their organizations (e.g. by leading by example and compassionate to their staff). © 2016 International Council of Nurses.

The aim of this study was to examine self-perceived compassion fatigue and compassion satisfaction among family physicians in Bosnia and Herzegovina and describe potential contributing factors. The cross-sectional study enrolled 120 family physicians. Professional quality of life compassion satisfaction and fatigue version 5 (ProQOL5) was used to assess compassion satisfaction and two components of compassion fatigue, secondary traumatic stress and burnout. The symptoms of chronic fatigue were evaluated using the Chalder fatigue scale. The majority of family physicians had moderate levels of compassion satisfaction (70%), burnout (75%) and secondary traumatic stress (55.8%). Family physicians with higher levels of secondary traumatic stress reported chronic fatigue (p = 0.001), longer length of service (p = 0.024) and residency training (p = 0.041). Chronic fatigue (p = 0.001), living in a rural environment (p = 0.033), larger size of practice (p = 0.006) and high number of patients with chronic disease (p = 0.001) were associated with a higher risk of burnout. Family physicians with large practices, long years of experience, a high number of chronically ill patients and experiencing chronic fatigue are at risk of developing compassion fatigue. A systematic exploration of compassion fatigue in relation to working conditions might provide an appropriate starting point for the development of preventive interventions.

MARTA: a high-energy cosmic-ray detector concept for high-accuracy muon measurement

DOE Office of Scientific and Technical Information (OSTI.GOV)

Abreu, P.; Andringa, S.; Assis, P.

A new concept for the direct measurement of muons in air showers is presented. The concept is based on resistive plate chambers (RPCs), which can directly measure muons with very good space and time resolution. The muon detector is shielded by placing it under another detector able to absorb and measure the electromagnetic component of the showers such as a water-Cherenkov detector, commonly used in air shower arrays. Here, the combination of the two detectors in a single, compact detector unit provides a unique measurement that opens rich possibilities in the study of air showers.

The muon detector is shielded by placing it under another detector able to absorb and measure the electromagnetic component of the showers such as a water-Cherenkov detector, commonly used in air shower arrays. The combination of the two detectors in a single, compact detector unit provides a unique measurement that opens rich possibilities in the study of air showers.

This study investigated whether self-compassion and emotional invalidation (perceiving others as indifferent to one's emotions) may explain the relationship of childhood exposure to adverse parenting and adult psychopathology in psychiatric outpatients (N=326). Path analysis was used to investigate associations between exposure to adverse parenting (abuse and indifference), self-compassion, emotional invalidation, and mental health when controlling for gender and age. Self-compassion was strongly inversely associated with emotional invalidation, suggesting that a schema that others will be unsympathetic or indifferent toward one's emotions may affect self-compassion and vice versa. Both self-compassion and emotional invalidation mediated the relationship between parental indifference and mental health outcomes. These preliminary findings suggest the potential utility of self-compassion and emotional schemas as transdiagnostic treatment targets. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Self-compassion is associated with depression and anxiety in general samples. Although recent research indicates that dysfunctional maternal attitudes predict the development of perinatal depression and anxiety symptoms, no research to date has examined the construct of self-compassion and its relationship with psychological well-being in perinatal women. Pregnant and postpartum women (N = 189) completed self-report measures of depression and anxiety history, current depression and anxiety symptom severity, and self-compassion. Women with higher depression and anxiety symptom severity had significantly lower self-compassion. Additionally, women with self-reported prior history of depression or anxiety had significantly lower self-compassion even while controlling for current depression or anxiety symptom severity, respectively. Our results suggest that self-compassion warrants further attention in the study of the development, maintenance, and treatment of perinatal mood and anxiety disorders.

Using a mixed methods research design, we explored self-compassion and eudaimonic well-being in young women athletes. In a quantitative study (n = 83), we found that self-compassion and eudaimonic well-being were positively related (r = .76, p < .01). A model of multiple mediation was proposed, with self-compassion, passivity, responsibility, initiative, and self-determination accounting for 83% of the variance in eudaimonic well-being. In a qualitative study (n = 11), we explored when and how self-compassion might be useful in striving to reach one's potential in sport. Self-compassion was described as advantageous in difficult sport-specific situations by increasing positivity, perseverance, and responsibility, as well as decreasing rumination. Apprehensions about fully embracing a self-compassionate mindset in sport warrant additional research to explore the seemingly paradoxical role of self-compassion in eudaimonic well-being.

Compassion: An Evolutionary Analysis and Empirical Review

Goetz, Jennifer L.; Keltner, Dacher; Simon-Thomas, Emiliana

2010-01-01

What is compassion? And how did it evolve? In this review, we integrate three evolutionary arguments that converge on the hypothesis that compassion evolved as a distinct affective experience whose primary function is to facilitate cooperation and protection of the weak and those who suffer. Our empirical review reveals compassion to have distinct appraisal processes attuned to undeserved suffering, distinct signaling behavior related to caregiving patterns of touch, posture, and vocalization, and a phenomenological experience and physiological response that orients the individual to social approach. This response profile of compassion differs from those of distress, sadness, and love, suggesting that compassion is indeed a distinct emotion. We conclude by considering how compassion shapes moral judgment and action, how it varies across different cultures, and how it may engage specific patterns of neural activation, as well as emerging directions of research.

The CBM RICH detector is an integral component of the future CBM experiment at FAIR, providing efficient electron identification and pion suppression necessary for the measurement of rare dileptonic probes in heavy ion collisions. The RICH design is based on CO2 gas as radiator, a segmented spherical glass focussing mirror with Al+MgF2 reflective coating, and Multianode Photomultipliers for efficient Cherenkov photon detection. Hamamatsu H12700 MAPMTs have recently been selected as photon sensors, following an extensive sensor evaluation, including irradiation tests to ensure sufficient radiation hardness of the MAPMTs. A brief overview of the detector design and concept is given, results on the radiation hardness of the photon sensors are shown, and the development of a FPGA-TDC based readout chain is discussed.

Background Healthcare providers are considered the primary conduit of compassion in healthcare. Although most healthcare providers desire to provide compassion, and patients and families expect to receive it, an evidence-based understanding of the construct and its associated dimensions from the perspective of healthcare providers is needed. Objectives The aim of this study was to investigate healthcare providers’ perspectives and experiences of compassion in order to generate an empirically derived, clinically informed model. Design Data were collected via focus groups with frontline healthcare providers and interviews with peer-nominated exemplary compassionate healthcare providers. Data were independently and collectively analysed by the research team in accordance with Straussian grounded theory. Setting and participants 57 healthcare providers were recruited from urban and rural palliative care services spanning hospice, home care, hospital-based consult teams, and a dedicated inpatient unit within Alberta, Canada. Results Five categories and 13 associated themes were identified, illustrated in the Healthcare Provider Compassion Model depicting the dimensions of compassion and their relationship to one another. Compassion was conceptualised as—a virtuous and intentional response to know a person, to discern their needs and ameliorate their suffering through relational understanding and action. Conclusions An empirical foundation of healthcare providers’ perspectives on providing compassionate care was generated. While the dimensions of the Healthcare Provider Compassion Model were congruent with the previously developed Patient Model, further insight into compassion is now evident. The Healthcare Provider Compassion Model provides a model to guide clinical practice and research focused on developing interventions, measures and resources to improve it. PMID:29540416

Design Study of DESCANT - DEuterated SCintillator Array for Neutron Tagging

Wong, James; Garrett, P. E.

2007-10-01

The fusion-evaporation reaction has been a useful tool for studying nuclei. A program of such reactions is being planned to take place at the TRIUMF facility in Vancouver, Canada using the TIGRESS array of gamma-ray detectors. A particular advantage of using these reactions is that they probe nuclei at moderate-to-high angular momenta. It would be of great interest to extend the study of high-spin states to neutron-rich systems. Following the formation of the fused compound system, the highly-excited state may lose energy by ``evaporating'' particles. Neutron evaporation is the predominant decay mode from neutron-rich compound systems so neutron detectors will be required. The probability of neutrons multiple scattering is quite high so a detector array must be able to differentiate between multiple neutrons evaporating from the reaction and a single neutron scattering multiple times. To address this issue we investigate the use of a novel neutron detector array -- one based on an array of deuterated liquid scintillators as neutron detectors. Results from early feasibility tests will be presented, along with the status of our GEANT4 simulations of the array performance.

Using Acceptance and Commitment Therapy to Increase Self-Compassion: A Randomized Controlled Trial

Yadavaia, James E.; Hayes, Steven C.; Vilardaga, Roger

2014-01-01

Self-compassion has been shown to be related to several types of psychopathology, including traumatic stress, and has been shown to improve in response to various kinds of interventions. Current conceptualizations of self-compassion fit well with the psychological flexibility model, which underlies acceptance and commitment therapy (ACT). However, there has been no research on ACT interventions specifically aimed at self-compassion. This randomized trial therefore compared a 6-hour ACT-based workshop targeting self-compassion to a wait-list control. From pretreatment to 2-month follow-up, ACT was significantly superior to the control condition in self-compassion, general psychological distress, and anxiety. Process analyses revealed psychological flexibility to be a significant mediator of changes in self-compassion, general psychological distress, depression, anxiety, and stress. Exploratory moderation analyses revealed the intervention to be of more benefit in terms of depression, anxiety, and stress to those with greater trauma history. PMID:25506545

Self-compassion training modulates alpha-amylase, heart rate variability, and subjective responses to social evaluative threat in women

2014-01-01

A growing body of research has revealed that social evaluative stressors trigger biological and psychological responses that in chronic forms have been linked to aging and disease. Recent research suggests that self-compassion may protect the self from typical defensive responses to evaluation. We investigated whether brief training in self-compassion moderated biopsychological responses to the Trier Social Stress Test (TSST) in women. Compared to attention (placebo) and no-training control conditions, brief self-compassion training diminished sympathetic (salivary alpha-amylase), cardiac parasympathetic, and subjective anxiety responses, though not HPA-axis (salivary cortisol) responses to the TSST. Self-compassion training also led to greater self-compassion under threat relative to the control groups. In that social stress pervades modern life, self-compassion represents a promising approach to diminishing its potentially negative psychological and biological effects. PMID:24636501

Is compassion essential to nursing practice?

PubMed

Hem, Marit Helene; Heggen, Kristin

2004-01-01

The Norwegian Nurses' Association recently (2001) approved a new code of ethics that included compassion as one of the basic values in nursing care. This paper examines the idea of compassion in the context of the Bible story of the Good Samaritan using an analysis of qualitative data from nurses' clinical work with psychiatric patients. The aim is to show how the idea of compassion challenges nursing practice. Thereafter, the paper discusses the benefits of and premises for compassion in care work. The results show that nurses tend not to be guided by compassion in their work with patients. The organisation of the day-to-day work in the hospital ward, the division of labour between nurses and doctors, and the nurses' approach to nursing were identified as influencing this tendency. The study shows that compassion is a radical concept with a potential to promote greater respect for patients' dignity.

Compassion Fatigue in Adult Daughter Caregivers of a Parent with Dementia

Day, Jennifer R.; Anderson, Ruth A.; Davis, Linda L.

2015-01-01

Adult daughters face distinct challenges caring for parents with dementia and may experience compassion fatigue: the combination of helplessness, hopelessness, an inability to be empathic, and a sense of isolation resulting from prolonged exposure to perceived suffering. Prior research on compassion fatigue has focused on professional healthcare providers and has overlooked filial caregivers. This study attempts to identify and explore risk factors for compassion fatigue in adult daughter caregivers and to substantiate further study of compassion fatigue in family caregivers. We used content analysis of baseline interviews with 12 adult daughter caregivers of a parent with dementia who participated in a randomized trial of homecare training. Four themes were identified in adult daughter caregiver interviews: (a) uncertainty; (b) doubt; (c) attachment; and (d) strain. Findings indicated adult daughter caregivers are at risk for compassion fatigue, supporting the need for a larger study exploring compassion fatigue in this population. PMID:25259643

Compassion fatigue and burnout: what managers should know.

PubMed

Slatten, Lise Anne; David Carson, Kerry; Carson, Paula Phillips

2011-01-01

Most health care employees experience and are bolstered by compassion satisfaction as they deal with patients in need. However, the more empathetic a health care provider is, the more likely he or she will experience compassion fatigue. Compassion fatigue is a negative syndrome that occurs when dealing with the traumatic experiences of patients, and examples of symptoms include intrusive thoughts, sleeping problems, and depression. Compassion fatigue is different from burnout. Compassion fatigue is a rapidly occurring disorder for primary health care workers who work with suffering patients, whereas burnout, a larger construct, is a slowly progressing disorder for employees who typically are working in burdensome organizational environments. Managers can mitigate problems associated with compassion fatigue with a number of interventions including patient reassignments, formal mentoring programs, employee training, and a compassionate organizational culture. With burnout, health care managers will want to focus primarily on chronic organizational problems.

Compassion, pride, and social intuitions of self-other similarity.

PubMed

Oveis, Christopher; Horberg, E J; Keltner, Dacher

2010-04-01

Compassion and pride serve contrasting social functions: Compassion motivates care-taking behavior, whereas pride enables the signaling and negotiation of rank within social hierarchies. Across 3 studies, compassion was associated with increased perceived self-other similarity, particularly to weak or vulnerable others. In contrast, pride was associated with an enhanced sense of similarity to strong others, and a decreased sense of similarity to weak others. These findings were obtained using trait measures (Study 1) and experimental inductions (Studies 2 and 3) of compassion and pride, examining the sense of similarity to strong or weak groups (Studies 1 and 2) and unfamiliar individuals (Study 3). The influences of compassion and pride on perceived self-other similarity could not be accounted for by positive mood, nor was this effect constrained by the ingroup status of the target group or individual. Discussion focuses on the contributions these findings make to an understanding of compassion and pride.

A visual pathway links brain structures active during magnetic compass orientation in migratory birds.

PubMed

Heyers, Dominik; Manns, Martina; Luksch, Harald; Güntürkün, Onur; Mouritsen, Henrik

2007-09-26

The magnetic compass of migratory birds has been suggested to be light-dependent. Retinal cryptochrome-expressing neurons and a forebrain region, "Cluster N", show high neuronal activity when night-migratory songbirds perform magnetic compass orientation. By combining neuronal tracing with behavioral experiments leading to sensory-driven gene expression of the neuronal activity marker ZENK during magnetic compass orientation, we demonstrate a functional neuronal connection between the retinal neurons and Cluster N via the visual thalamus. Thus, the two areas of the central nervous system being most active during magnetic compass orientation are part of an ascending visual processing stream, the thalamofugal pathway. Furthermore, Cluster N seems to be a specialized part of the visual wulst. These findings strongly support the hypothesis that migratory birds use their visual system to perceive the reference compass direction of the geomagnetic field and that migratory birds "see" the reference compass direction provided by the geomagnetic field.

A daily diary study of self-compassion, body image, and eating behavior in female college students.

PubMed

Kelly, Allison C; Stephen, Elizabeth

2016-06-01

Although self-compassion is associated with healthier body image and eating behavior, these findings have generally emerged at the between-persons level only. The present study investigated the unique contributions of within-person variability in self-compassion, and between-persons differences in self-compassion, to body image and eating behavior. Over seven days, 92 female college students completed nightly measures of self-compassion, self-esteem, dietary restraint, intuitive eating, body appreciation, body satisfaction, and state body image. Multilevel modeling revealed that within-persons, day-to-day fluctuations in self-compassion contributed to day-to-day fluctuations in body image and eating. Between-persons, participants' average levels of self-compassion across days contributed to their average levels of body image and eating over the week. Results generally held when controlling for within- and between-persons self-esteem. Evidently, the eating and body image benefits of self-compassion may come not only from being a generally self-compassionate person, but also from treating oneself more self-compassionately than usual on a given day.

Sacco, Tara L; Ciurzynski, Susan M; Harvey, Megan Elizabeth; Ingersoll, Gail L

2015-08-01

Although critical care nurses gain satisfaction from providing compassionate care to patients and patients' families, the nurses are also at risk for fatigue. The balance between satisfaction and fatigue is considered professional quality of life. To establish the prevalence of compassion satisfaction and compassion fatigue in adult, pediatric, and neonatal critical care nurses and to describe potential contributing demographic, unit, and organizational characteristics. In a cross-sectional design, nurses were surveyed by using a demographic questionnaire and the Professional Quality of Life Scale to measure levels of compassion fatigue and compassion satisfaction. Nurses (n = 221) reported significant differences in compassion satisfaction and compassion fatigue on the basis of sex, age, educational level, unit, acuity, change in nursing management, and major systems change. Understanding the elements of professional quality of life can have a positive effect on work environment. The relationship between professional quality of life and the standards for a healthy work environment requires further investigation. Once this relationship is fully understood, interventions to improve this balance can be developed and tested. ©2015 American Association of Critical-Care Nurses.

The objective of this study was to extend the psychometric evaluation of a brief version of the Self Compassion Scale (SCS). A secondary analysis of data from an international sample of 1,967 English-speaking persons living with HIV disease was used to examine the factor structure, and reliability of the 12-item Brief Version Self Compassion Inventory (BVSCI). A Maximum Likelihood factor analysis and Oblimin with Kaiser Normalization confirmed a two-factor solution, accounting for 42.58% of the variance. The BVSCI supported acceptable internal consistencies, with .714 for the total scale and .822 for Factor I and .774 for Factor II. Factor I (lower self compassion) demonstrated strongly positive correlations with measures of anxiety and depression while Factor II (high self compassion) was inversely correlated with the measures. No significant differences were found in the BVSCI scores for gender, age, or having children. Levels of self-compassion were significantly higher in persons with HIV disease and other physical and psychological health conditions. The scale shows promise for the assessment of self-compassion in persons with HIV without taxing participants, and may prove essential in investigating future research aimed at examining correlates of self-compassion, as well as providing data for tailoring self-compassion interventions for persons with HIV.

Compassionate work appears paradoxical as it may provide great rewards, but may also come at great costs to care providers. This paper explores the paradox of compassionate work by examining what interactions contribute to compassion satisfaction and what interactions contribute to compassion fatigue. This mixed-methods, cross-sectional study uses qualitative interview data from animal health care providers (N = 20) to identify work interactions that they find satisfying or stressful. Quantitative survey data (N = 572) are used to test hypotheses generated from the interviews regarding predictors of compassion satisfaction and compassion fatigue. Interview transcripts were analyzed using a directed content analysis approach. Survey data were analyzed using ordinary least squares regression. The results highlight the complex nature of compassionate work. As hypothesized, making a difference to animals and building relationships with animal patients and human clients relate to greater compassion satisfaction. Human client barriers to animal care and witnessing client grief relate to greater compassion fatigue, as predicted. None of the predictors relate to less compassion fatigue, but forming relationships with animal patients relates to both greater compassion satisfaction and compassion fatigue. This paper enhances our understanding of provider-client-patient interactions and highlights the paradox of compassionate work.

Therapists who work with trauma survivors, such as survivors of sexual violence, can experience compassion satisfaction while experiencing negative effects of trauma work, such as secondary traumatic stress. We examined whether the negative effects of secondary traumatic stress on therapist adjustment would be buffered by compassion satisfaction and whether the broaden-and-build theory of positive emotions could be applied to examine the factors (positive emotions and positive reframing) that relate to compassion satisfaction. Sixty-one therapists who work with sexual violence survivors completed measures of secondary traumatic stress, compassion satisfaction, adjustment, positive emotions and positive reframing. Hierarchical multiple regression analyses found that compassion satisfaction buffered the negative impact of secondary traumatic stress on therapist adjustment when adjustment was conceptualised as anxiety. Using non-parametric bootstrapping, we found that the relationship between greater positive emotions and greater compassion satisfaction was partially mediated by positive reframing. The findings indicate that compassion satisfaction is likely to be helpful in ameliorating the negative effects of secondary traumatic stress on anxiety in therapists who work with sexual violence survivors and that the broaden-and-build theory of positive emotions may provide a strong theoretical basis for the further examination of compassion satisfaction in trauma therapists.

Decreased well-being of healthcare workers expressed as stress and decreased job satisfaction influences patient safety, patient satisfaction, and cost containment. Self-compassion has garnered recent attention due to its positive association with well-being and happiness. Discovering novel pathways to increase the well-being of healthcare workers is essential. This study sought to explore the influence of self-compassion on employee happiness in healthcare professionals. A total of 400 participants (mean age = 45 ± 14, 65% female) healthcare workers at a large teaching hospital were randomly asked to complete questionnaires assessing their levels of happiness and self-compassion, life conditions, and habits. Participants completed the Happiness Scale and Self-Compassion Scales, the Five Facet Mindfulness Questionnaire as well as variables associated with well-being: relationship status, the number of hours spent exercising a week, attendance at a wellness facility, and engagement in a regular spiritual practice. Self-compassion was significantly and independently associated with perceived happiness explaining 39% of its variance after adjusting for age, marital status, gender, time spent exercising, and attendance to an exercise facility. Two specific subdomains of self-compassion from the instrument used, coping with isolation and mindfulness, accounted for 95% of the self-compassion effect on happiness. Self-compassion is meaningfully and independently associated with happiness and well-being in healthcare professionals. Our results may have practical implications by providing specific self-compassion components to be targeted in future programs aimed at enhancing well-being in healthcare professionals.

Magnetic compass information has a key role in bird orientation, but the physiological mechanisms enabling birds to sense the Earth's magnetic field remain one of the unresolved mysteries in biology. Two biophysical mechanisms have become established as the most promising magnetodetection candidates. The iron-mineral-based hypothesis suggests that magnetic information is detected by magnetoreceptors in the upper beak and transmitted through the ophthalmic branch of the trigeminal nerve to the brain. The light-dependent hypothesis suggests that magnetic field direction is sensed by radical pair-forming photopigments in the eyes and that this visual signal is processed in cluster N, a specialized, night-time active, light-processing forebrain region. Here we report that European robins with bilateral lesions of cluster N are unable to show oriented magnetic-compass-guided behaviour but are able to perform sun compass and star compass orientation behaviour. In contrast, bilateral section of the ophthalmic branch of the trigeminal nerve in European robins did not influence the birds' ability to use their magnetic compass for orientation. These data show that cluster N is required for magnetic compass orientation in this species and indicate that it may be specifically involved in processing of magnetic compass information. Furthermore, the data strongly suggest that a vision-mediated mechanism underlies the magnetic compass in this migratory songbird, and that the putative iron-mineral-based receptors in the upper beak connected to the brain by the trigeminal nerve are neither necessary nor sufficient for magnetic compass orientation in European robins.

Influence of fears of compassion on body image shame and disordered eating.

The current study tested a path model examining the impact of fears of compassion in the adoption of disordered eating and whether social safeness and body shame would mediate this relationship. Participants were 645 women (aged between 18 and 55) from the general community, who completed an online survey. Results indicated that fears of compassion were negatively associated with one's ability to feel secure and safe within close relationships, and positively linked with higher levels of body shame and disordered eating. The tested model accounted for 62% of the variance of disordered eating. Path analyses results revealed that the three dimensions of fears of compassion impacted on disordered eating. Particularly, fear of expressing compassion for others presented a direct impact on disordered eating. Moreover, fears of self-compassion and fears of receiving compassion from others partially impacted on disordered eating attitudes and behaviours, through the mechanisms of social safeness and body image-focused shame. These findings suggested that women who present higher levels of fear of self-compassion and of receiving signs of affection and compassion from others tend to feel more insecure in their social group, which seem explain body shame and the engagement in disordered eating behaviours. This study highlights the pathogenic impact of fears of compassion on body image and eating attitudes and behaviours. The current data seem to offer relevant insights for research and clinical practice, by supporting the relevance of developing compassionate abilities and attitudes to target body image and eating-related difficulties.

Effect of Meaningful Recognition on Critical Care Nurses' Compassion Fatigue.

As caregivers in high-pressure environments, critical care nurses are at risk for burnout and secondary trauma-components of compassion fatigue. Recent findings have increased understanding of the phenomena, specifically that satisfaction and meaningful recognition may play a role in reducing burnout and raising compassion satisfaction; however, no large multisite studies of compassion fatigue have been conducted. To examine the effect of meaningful recognition and other predictors on compassion fatigue in a multicenter national sample of critical care nurses. A quantitative, descriptive online survey was completed by 726 intensive care unit nurses in 14 hospitals with an established meaningful recognition program and 410 nurses in 10 hospitals without such a program. Site coordinators at each hospital coordinated distribution of the survey to nurses to assess multiple predictors against outcomes, measured by the Professional Quality of Life Scale. Cross-validation and linear regression modeling were conducted to determine significant predictors of burnout, secondary traumatic stress, and compassion satisfaction. Similar levels of burnout, secondary traumatic stress, compassion satisfaction, overall satisfaction, and intent to leave were reported by nurses in hospitals with and without meaningful recognition programs. Meaningful recognition was a significant predictor of decreased burnout and increased compassion satisfaction. Additionally, job satisfaction and job enjoyment were highly predictive of decreased burnout, decreased secondary traumatic stress, and increased compassion satisfaction. In addition to acknowledging and valuing nurses' contributions to care, meaningful recognition could reduce burnout and boost compassion satisfaction. ©2017 American Association of Critical-Care Nurses.

Quality of working life includes elements such as autonomy, trust, ergonomics, participation, job complexity, and work-life balance. The overarching aim of this study was to investigate if and how quality of working life affects Compassion Fatigue, Burnout, and Compassion Satisfaction among mental health practitioners. Staff working in three Italian Mental Health Departments completed the Professional Quality of Life Scale, measuring Compassion Fatigue, Burnout, and Compassion Satisfaction, and the Quality of Working Life Questionnaire. The latter was used to collect socio-demographics, occupational characteristics and 13 indicators of quality of working life. Multiple regressions controlling for other variables were undertaken to predict Compassion Fatigue, Burnout, and Compassion Satisfaction. Four hundred questionnaires were completed. In bivariate analyses, experiencing more ergonomic problems, perceiving risks for the future, a higher impact of work on life, and lower levels of trust and of perceived quality of meetings were associated with poorer outcomes. Multivariate analysis showed that (a) ergonomic problems and impact of work on life predicted higher levels of both Compassion Fatigue and Burnout; (b) impact of life on work was associated with Compassion Fatigue and lower levels of trust and perceiving more risks for the future with Burnout only; (c) perceived quality of meetings, need of training, and perceiving no risks for the future predicted higher levels of Compassion Satisfaction. In order to provide adequate mental health services, service providers need to give their employees adequate ergonomic conditions, giving special attention to time pressures. Building trustful relationships with management and within the teams is also crucial. Training and meetings are other important targets for potential improvement. Additionally, insecurity about the future should be addressed as it can affect both Burnout and Compassion Satisfaction. Finally, strategies to reduce possible work-life conflicts need to be considered.

The emotion of compassion and the likelihood of its expression in nursing practice.

PubMed

Newham, Roger Alan

2017-07-01

Philosophical and empirical work on the nature of the emotions is extensive, and there are many theories of emotions. However, all agree that emotions are not knee jerk reactions to stimuli and are open to rational assessment or warrant. This paper's focus is on the condition or conditions for compassion as an emotion and the likelihood that it or they can be met in nursing practice. Thus, it is attempting to keep, as far as possible, compassion as an emotion separate from both moral norms and professional norms. This is because empirical or causal conditions that can make experiencing and acting out of compassion difficult seem especially relevant in nursing practice. I consider how theories of emotion in general and of compassion in particular are somewhat contested, but all recent accounts agree that emotions are not totally immune to reason. Then, using accounts of constitutive conditions of the emotion of compassion, I will show how they are often likely to be quite fragile or unstable in practice and particularly so within much nursing practice. In addition, some of the conditions for compassion will be shown to be problematic for nursing practice. It is difficult to keep ideas of compassion separate from morality, and this connection is noticeable in the claims made of compassion for nursing and so I will briefly highlight one such connection that of the need for normative theory to give an account of the value that emotions such as compassion presume and that compassionate motivation is separate from moral motivation and may conflict with it. The fragility or instability of the emotion of compassion in practice has implications for both what can be expected and what should be expected of compassion; at least if what is wanted is a realist rather than idealist account of "should." © 2016 John Wiley & Sons Ltd.

'Good ethics and moral standing': a qualitative study of aesthetic leadership in clinical nursing practice.

To explore how aesthetic leadership is embodied by clinical leaders in the nursing workplace. A number of different leadership styles have been developed, theorised and applied to the nursing workforce over the years. Many of these styles lack an explicit moral dimension in their identified leader attributes, due to a shift in theorising of leadership to focus on the impact of leader traits on followers. It is timely to look at aesthetic leadership, with its explicit moral dimension, as a way of improving outcomes for nurses, patients and health care organisations. Qualitative design, using conversation-style interviews with experienced registered nurses in designated clinical leadership roles. Twelve experienced registered nurses who worked in designated clinical leadership roles participated in an individual, digitally recorded, semi-structured conversation-style interview. Narrative data were transcribed and subject to thematic analysis. Three main themes emerged: 'True to their beliefs': embodying principled practice; 'Not all policies fit every patient': ethical leadership in ambiguous situations; and 'Being open to people's concerns': providing fair and just solutions. A strong moral compass shaped and guided participants' day-to-day clinical leadership activities. Participants provided a rich narrative on how aesthetic leadership is embodied in the clinical nursing setting. It was evident that their clinical leadership is shaped and guided by a strong moral compass. By incorporating into their practice an aesthetic world-view with its strong moral purpose, participants in this study have shown how aesthetic leadership can enhance the clinical nursing workplace. Nurses in the clinical setting value clinical leaders who embrace and operate with a strong moral compass. Aesthetic leadership, with its explicit strong moral purpose, offers a way of incorporating morality into clinical leadership in the nursing workplace. © 2015 John Wiley & Sons Ltd.

Calibration of magnetic and celestial compass cues in migratory birds--a review of cue-conflict experiments.

PubMed

Muheim, Rachel; Moore, Frank R; Phillips, John B

2006-01-01

Migratory birds use multiple sources of compass information for orientation, including the geomagnetic field, the sun, skylight polarization patterns and star patterns. In this paper we review the results of cue-conflict experiments designed to determine the relative importance of the different compass mechanisms, and how directional information from these compass mechanisms is integrated. We focus on cue-conflict experiments in which the magnetic field was shifted in alignment relative to natural celestial cues. Consistent with the conclusions of earlier authors, our analyses suggest that during the premigratory season, celestial information is given the greatest salience and used to recalibrate the magnetic compass by both juvenile and adult birds. Sunset polarized light patterns from the region of the sky near the horizon appear to provide the calibration reference for the magnetic compass. In contrast, during migration, a majority of experiments suggest that birds rely on the magnetic field as the primary source of compass information and use it to calibrate celestial compass cues, i.e. the relative saliency of magnetic and celestial cues is reversed. An alternative possibility, however, is suggested by several experiments in which birds exposed to a cue conflict during migration appear to have recalibrated the magnetic compass, i.e. their response is similar to that of birds exposed to cue conflicts during the premigratory season. The general pattern to emerge from these analyses is that birds exposed to the cue conflict with a view of the entire sunset sky tended to recalibrate the magnetic compass, regardless of whether the cue conflict occurred during the premigratory or migratory period. In contrast, birds exposed to the cue conflict in orientation funnels and registration cages that restricted their view of the region of sky near the horizon (as was generally the case in experiments carried out during the migratory season) did not recalibrate the magnetic compass but, instead, used the magnetic compass to calibrate the other celestial compass systems. If access to critical celestial cues, rather than the timing of exposure to the cue conflict (i.e. premigratory vs migratory), determines whether recalibration of the magnetic compass occurs, this suggests that under natural conditions there may be a single calibration reference for all of the compass systems of migratory birds that is derived from sunset (and possibly also sunrise) polarized light cues from the region of sky near the horizon. In cue-conflict experiments carried out during the migratory season, there was also an interesting asymmetry in the birds' response to magnetic fields shifted clockwise and counterclockwise relative to celestial cues. We discuss two possible explanations for these differences: (1) lateral asymmetry in the role of the right and left eye in mediating light-dependent magnetic compass orientation and (2) interference from the spectral and intensity distribution of skylight at sunset with the response of the light-dependent magnetic compass.

The proposal addresses studies of nuclear structure at low-energies and development of instrumentation for that purpose. The structure studies deal with features of neutron-rich nuclei with unexplored shapes (football- or pear-shaped nuclei). The regions of interest are: neutron rich nuclei like 132-138Sn, or 48-54Ca, and the Zr, Mo, and Ru isotopes. The tools used can be grouped as follows: either Gammasphere or Gretina multi-gamma detector arrays and auxiliary detectors (Microball, Neutron Shell, and the newly completed Phoswich Wall).The neutron-rich nuclei are accessed by radioactive-beam binary reactions or by 252Cf spontaneous fission. The experiments with heavy radioactive beams aim at excitingmore » the beam nuclei by pick-up or transfer a neutron or a proton from a light target like 13C, 9Be, 11B or 14N .For these binary-reaction studies the Phoswich Wall detector system is essential. It is based on four multi-anode photomultiplier tubes on which CsI and thin fast-timing plastic scintillators are attached. Their signals are digitized with a high density microchip system.« less

The Compressed Baryonic Matter (CBM) experiment at the future FAIR facility will investigate the QCD phase diagram at high net baryon densities and moderate temperatures in A+A collisions from 2 to 11 AGeV (SIS100). Electron identification in CBM will be performed by a Ring Imaging Cherenkov (RICH) detector and Transition Radiation Detectors (TRD). A real size prototype of the RICH detector was tested together with other CBM groups at the CERN PS/T9 beam line in 2014. For the first time the data format used the FLESnet protocol from CBM delivering free streaming data. The analysis was fully performed within the CBMROOT framework. In this contribution the data analysis and the event reconstruction methods which were used for obtained data are discussed. Rings were reconstructed using an algorithm based on the Hough Transform method and their parameters were derived with high accuracy by circle and ellipse fitting procedures. We present results of the application of the presented algorithms. In particular we compare results with and without Wavelength shifting (WLS) coating.

An experimental program to measure spectroscopic properties of neutron-rich nuclei in the A = 80 region is underway at the Holifield Radioactive Ion Beam Facility. Our approach has been to get a comprehensive picture of the shell structure in this region by studying a series of properties of low lying states (E(2+), B(E2), g-factors and quadrupole moments). The beams, instrumentation and techniques developed specifically for this purpose have allowed us to systematically study the behavior of these observables along isotopic and isotonic chains using both stable and radioactive nuclei under almost identical experimental conditions. We have developed many techniques and detectors for in-beam gamma spectroscopy with radioactive ion beams. Most of the detectors can be used individually or in combination. Generally these detector systems have very large efficiencies. We give examples of their use from three recent experiments; namely, Coulomb excitation of n-rich nuclei along the N = 50 shell closure, the static quadrupole moment of the first 2+ in 78Ge and g-factor measurements of n-rich isotopes near N = 50.

Self-Compassion and Relationship Maintenance: The Moderating Roles of Conscientiousness and Gender

PubMed Central

Baker, Levi; McNulty, James K.

2010-01-01

Should intimates respond to their interpersonal mistakes with self-criticism or with self-compassion? Although it is reasonable to expect self-compassion to benefit relationships by promoting self-esteem, it is also reasonable to expect self-compassion to hurt relationships by removing intimates’ motivation to correct their interpersonal mistakes. Two correlational studies, 1 experiment, and 1 longitudinal study demonstrated that whether self-compassion helps or hurts relationships depends on the presence versus absence of dispositional sources of the motivation to correct interpersonal mistakes. Among men, the implications of self-compassion were moderated by conscientiousness. Among men high in conscientiousness, self-compassion was associated with greater motivation to correct interpersonal mistakes (Studies 1 and 3), observations of more-constructive problem-solving behaviors (Study 2), reports of more accommodation (Study 3), and fewer declines in marital satisfaction that were mediated by decreases in interpersonal problem severity (Study 4); among men low in conscientiousness, self-compassion was associated with these outcomes in the opposite direction. Among women, in contrast, likely because women are inherently more motivated than men to preserve their relationships for cultural and/or biological reasons, self-compassion was never harmful to the relationship. Instead, women’s self-compassion was positively associated with the motivation to correct their interpersonal mistakes (Study 1) and changes in relationship satisfaction (Study 4), regardless of conscientiousness. Accordingly, theoretical descriptions of the implications of self-promoting thoughts for relationships may be most complete to the extent that they consider the presence versus absence of other sources of the motivation to correct interpersonal mistakes.

The purpose of this qualitative study was to investigate advanced cancer patients' perspectives on the importance, feasibility, teaching methods, and issues associated with training healthcare providers in compassionate care. This study utilized grounded theory, a qualitative research method, to develop an empirical understanding of compassion education rooted in direct patient reports. Audio-recorded semi-structured interviews were conducted to obtain an in-depth understanding of compassion training from the perspectives of hospitalized advanced cancer patients (n = 53). Data were analyzed in accordance with grounded theory to determine the key elements of the underlying theory. Three overarching categories and associated themes emerged from the data: compassion aptitude, cultivating compassion, and training methods. Participants spoke of compassion as an innate quality embedded in the character of learners prior to their healthcare training, which could be nurtured through experiential learning and reflective practices. Patients felt that the innate qualities that learners possessed at baseline were further fashioned by personal and practice experiences, and vocational motivators. Participants also provided recommendations for compassion training, including developing an interpersonal relationship with patients, seeing the patient as a person, and developing a human connection. Teaching methods that patients suggested in compassion training included patient-centered communication, self-reflection exercises, and compassionate role modeling. This study provides insight on compassion training for both current and future healthcare providers, from the perspectives of the end recipients of healthcare provider training - patients. Developing a theoretical base for patient centred, evidence-informed, compassion training is a crucial initial step toward the further development of this core healthcare competency.

Coordinating compass-based and nest-based flight directions during bumblebee learning and return flights.

Bumblebees tend to face their nest over a limited range of compass directions when learning the nest's location on departure and finding it on their approach after foraging. They thus obtain similar views of the nest and its surroundings on their learning and return flights. How do bees coordinate their flights relative to nest-based and compass-based reference frames to get such similar views? We show, first, that learning and return flights contain straight segments that are directed along particular compass bearings, which are independent of the orientation of a bee's body. Bees are thus free within limits to adjust their viewing direction relative to the nest, without disturbing flight direction. Second, we examine the coordination of nest-based and compass-based control during likely information gathering segments of these flights: loops during learning flights and zigzags on return flights. We find that bees tend to start a loop or zigzag when flying within a restricted range of compass directions and to fly towards the nest and face it after a fixed change in compass direction, without continuous interactions between their nest-based and compass-based directions of flight. A preferred trajectory of compass-based flight over the course of a motif, combined with the tendency of the bees to keep their body oriented towards the nest automatically narrows the range of compass directions over which bees view the nest. Additionally, the absence of interactions between the two reference frames allows loops and zigzags to have a stereotyped form that can generate informative visual feedback.

Preliminary evidence has demonstrated the benefits of targeting self-compassion in the treatment of posttraumatic stress disorder (PTSD). However, survivors of childhood maltreatment may present with unique challenges that compromise the effectiveness of these and other PTSD treatments. Specifically, childhood maltreatment victims often exhibit a marked fear and active resistance of self-kindness and warmth (i.e., fear of self-compassion). Victims may also attempt to control distressing internal experiences in a way that hinders engagement in value-based actions (i.e., psychological inflexibility). Research suggests that psychological inflexibility exacerbates the negative effects of fear of self-compassion. The present study expanded on previous research by examining the relations among childhood maltreatment, fear of self-compassion, psychological inflexibility, and PTSD symptom severity in 288 college women. As expected, moderate to severe levels of childhood maltreatment were associated with greater fear of self-compassion, psychological inflexibility, and PTSD symptom severity compared to minimal or no childhood maltreatment. A mediation analysis showed that childhood maltreatment had a significant indirect effect on PTSD symptom severity via fear of self-compassion, although a conditional process analysis did not support psychological inflexibility as a moderator of this indirect effect. A post hoc multiple mediator analysis showed a significant indirect effect of childhood maltreatment on PTSD symptom severity via psychological inflexibility, but not fear of self-compassion. These findings highlight the importance of addressing fear of self-compassion and psychological inflexibility as barriers to treatment for female survivors of childhood maltreatment.

To examine compassion fatigue and compassion satisfaction in acute care nurses across multiple specialties in a hospital-based setting. A cross-sectional electronic survey design was used to collect data from direct care nurses in a 700-bed, quaternary care, teaching facility in the southwestern United States. A total of 491 direct care registered nurses completed a survey measuring their professional quality of life (burnout, secondary traumatic stress, and compassion satisfaction). Analysis was conducted to assess for differences between demographics, specialties, job satisfaction, and intent to leave their current position. Significant predictors of burnout included lack of meaningful recognition, nurses with more years of experience, and nurses in the "Millennial" generation (ages 21-33 years). Receiving meaningful recognition, higher job satisfaction, nurses in the "Baby Boomer" generation (ages 50-65 years), and nurses with fewer years of experience significantly predicted compassion satisfaction. No significant differences were noted across nurse specialties, units, or departments. This study adds to the literature the impact meaningful recognition may have on compassion satisfaction and fatigue. Our findings provide a potential explanation for the lack of retention of nurses in the millennial generation who leave their positions with limited years of experience. Based on our research, meaningful recognition may increase compassion satisfaction, positively impact retention, and elevate job satisfaction. Compassion fatigue in nurses has clear implications for nursing retention and the quality of care. Organizations willing to invest in reducing compassion fatigue have the potential to improve financial savings by reducing turnover and adverse events associated with burnout. © 2015 Sigma Theta Tau International.

Compassion is considered an essential element in quality patient care. One of the conceptual challenges in healthcare literature is that compassion is often confused with sympathy and empathy. Studies comparing and contrasting patients' perspectives of sympathy, empathy, and compassion are largely absent. The aim of this study was to investigate advanced cancer patients' understandings, experiences, and preferences of "sympathy," "empathy," and "compassion" in order to develop conceptual clarity for future research and to inform clinical practice. Data were collected via semi-structured interviews and then independently analyzed by the research team using the three stages and principles of Straussian grounded theory. Data were collected from 53 advanced cancer inpatients in a large urban hospital. Constructs of sympathy, empathy, and compassion contain distinct themes and sub-themes. Sympathy was described as an unwanted, pity-based response to a distressing situation, characterized by a lack of understanding and self-preservation of the observer. Empathy was experienced as an affective response that acknowledges and attempts to understand individual's suffering through emotional resonance. Compassion enhanced the key facets of empathy while adding distinct features of being motivated by love, the altruistic role of the responder, action, and small, supererogatory acts of kindness. Patients reported that unlike sympathy, empathy and compassion were beneficial, with compassion being the most preferred and impactful. Although sympathy, empathy, and compassion are used interchangeably and frequently conflated in healthcare literature, patients distinguish and experience them uniquely. Understanding patients' perspectives is important and can guide practice, policy reform, and future research.

The hippocampal formation (HF) plays a crucial role in amniote spatial cognition. There are also indications of functional lateralization in the contribution of the left and right HF in processes that enable birds to navigate space. The experiments described in this study were designed to examine left and right HF differences in a task of sun compass-based spatial learning in homing pigeons (Columba livia). Control, left (HFL) and right (HFR) HF lesioned pigeons were trained in an outdoor arena to locate a food reward using their sun compass in the presence or absence of alternative feature cues. Subsequent to training, the pigeons were subjected to test sessions to determine if they learned to represent the goal location with their sun compass and the relative importance of the sun compass vs. feature cues. Under all test conditions, the control pigeons demonstrated preferential use of the sun compass in locating the goal. By contrast, the HFL pigeons demonstrated no ability to locate the goal by the sun compass but an ability to use the feature cues. The behaviour of the HFR pigeons demonstrated that an intact left HF is sufficient to support sun compass-based learning, but in conflict situations and in contrast to controls, they often relied on feature cues. In conclusion, only the left HF is capable of supporting sun compass-based learning. However, preferential use of the sun compass for learning requires an intact right HF. The data support the hypothesis that the left and right HF make different but complementary contributions toward avian spatial cognition.

Self-compassion and relationship maintenance: the moderating roles of conscientiousness and gender.

Baker, Levi R; McNulty, James K

2011-05-01

Should intimates respond to their interpersonal mistakes with self-criticism or with self-compassion? Although it is reasonable to expect self-compassion to benefit relationships by promoting self-esteem, it is also reasonable to expect self-compassion to hurt relationships by removing intimates' motivation to correct their interpersonal mistakes. Two correlational studies, 1 experiment, and 1 longitudinal study demonstrated that whether self-compassion helps or hurts relationships depends on the presence versus absence of dispositional sources of the motivation to correct interpersonal mistakes. Among men, the implications of self-compassion were moderated by conscientiousness. Among men high in conscientiousness, self-compassion was associated with greater motivation to correct interpersonal mistakes (Studies 1 and 3), observations of more constructive problem-solving behaviors (Study 2), reports of more accommodation (Study 3), and fewer declines in marital satisfaction that were mediated by decreases in interpersonal problem severity (Study 4); among men low in conscientiousness, self-compassion was associated with these outcomes in the opposite direction. Among women, in contrast, likely because women are inherently more motivated than men to preserve their relationships for cultural and/or biological reasons, self-compassion was never harmful to the relationship. Instead, women's self-compassion was positively associated with the motivation to correct their interpersonal mistakes (Study 1) and changes in relationship satisfaction (Study 4), regardless of conscientiousness. Accordingly, theoretical descriptions of the implications of self-promoting thoughts for relationships may be most complete to the extent that they consider the presence versus absence of other sources of the motivation to correct interpersonal mistakes.

Oncologist burnout and compassion fatigue: investigating time pressure at work as a predictor and the mediating role of work-family conflict.

PubMed

Kleiner, Sibyl; Wallace, Jean E

Oncologists are at high risk of poor mental health. Prior research has focused on burnout, and has identified heavy workload as a key predictor. Compassion fatigue among physicians has generally received less attention, although medical specialties such as oncology may be especially at risk of compassion fatigue. We contribute to research by identifying predictors of both burnout and compassion fatigue among oncologists. In doing so, we distinguish between quantitative workload (e.g., work hours) and subjective work pressure, and test whether work-family conflict mediates the relationships between work pressure and burnout or compassion fatigue. In a cross-sectional study, oncologists from across Canada (n = 312) completed questionnaires assessing burnout, compassion fatigue, workload, time pressure at work, work-family conflict, and other personal, family, and occupational characteristics. Analyses use Ordinary Least Squares regression. Subjective time pressure at work is a key predictor of both burnout and compassion fatigue. Our results also show that work-family conflict fully mediates these relationships. Overall, the models explain more of the variation in burnout as compared to compassion fatigue. Our study highlights the need to consider oncologists' subjective time pressure, in addition to quantitative workload, in interventions to improve mental health. The findings also highlight a need to better understand additional predictors of compassion fatigue.

Based on the observation data of Compass/GPSobserved at five stations, time span from July 1, 2014 to June 30, 2016. UsingPPP positioning model of the PANDA software developed by Wuhan University,Analyzedthe positioning accuracy of single system and Compass/GPS integrated resolving, and discussed the capability of Compass navigation system in crustal motion monitoring. The results showed that the positioning accuracy in the east-west directionof the Compass navigation system is lower than the north-south direction (the positioning accuracy de 3 times RMS), in general, the positioning accuracyin the horizontal direction is about 1 2cm and the vertical direction is about 5 6cm. The GPS positioning accuracy in the horizontal direction is better than 1cm and the vertical direction is about 1 2cm. The accuracy of Compass/GPS integrated resolving is quite to GPS. It is worth mentioning that although Compass navigation system precision point positioning accuracy is lower than GPS, two sets of velocity fields obtained by using the Nikolaidis (2002) model to analyze the Compass and GPS time series results respectively, the results showed that the maximum difference of the two sets of velocity field in horizontal directions is 1.8mm/a. The Compass navigation system can now be used to monitor the crustal movement of the large deformation area, based on the velocity field in horizontal direction.

This is the first two-phase Australian study to explore the factors impacting upon compassion satisfaction, compassion fatigue, anxiety, depression and stress and to describe the strategies nurses use to build compassion satisfaction into their working lives. Compassion fatigue has been found to impact on job satisfaction, the quality of patient care and retention within nursing. This study provides new knowledge on the influences of anxiety, stress and depression and how they relate to compassion satisfaction and compassion fatigue. In Phase 2 of the study, 10 nurses from Phase 1 of the study participated in individual interviews and a focus group. A semi-structured interview schedule guided the conversations with the participants. Data analysis resulted in seven main themes: social networks and support;infrastructure and support; environment and lifestyle; learning; leadership; stress; and suggestions to build psychological wellness in nurses. Findings suggest that a nurse’s capacity to cope is enhanced through strong social and collegial support, infrastructure that supports the provision of quality nursing care and positive affirmation. These concepts are strongly linked to personal resilience. for nursing management These findings support the need for management to develop appropriate interventions to build resilience in nurses.

Stomaching rejection: Self-compassion and self-esteem moderate the impact of daily social rejection on restrictive eating behaviours among college women.

Beekman, Janine B; Stock, Michelle L; Howe, George W

2017-11-01

The present study examined whether having high self-esteem or a self-compassionate perspective help mitigate the impact of daily social rejection on negative affect and restrictive eating behaviours. Following a baseline survey assessing self-esteem and self-compassion, 121 college women completed online daily diaries for one week. Negative affect and restrictive eating behaviours. On days when women reported more rejection, they also reported higher restrictive eating behaviours and greater negative affect. Effects were moderated by self-esteem and self-compassion, such that the lower participants were in self-esteem or self-compassion, the stronger the positive relation between rejection and negative affect and restrictive eating. However, only the common humanity/isolation dimension of self-compassion significantly moderated daily effects of rejection when controlling for self-esteem. Mediated moderation results reveal different mechanisms by which self-esteem and self-compassion buffer against rejections' effects on affect and restrictive eating. Self-compassion and self-esteem influence the complex impact that social rejection has on affect and restrictive eating. More than other dimensions of self-compassion or self-esteem, remembering one's common humanity can result in a healthier response to social rejection.

Intranasal administration of oxytocin increases compassion toward women

Palgi, Sharon; Klein, Ehud

2015-01-01

It has been suggested that the degree of compassion—the feeling of warmth, understanding and kindness that motivates the desire to help others, is modulated by observers’ views regarding the target’s vulnerability and suffering. This study tested the hypothesis that as compassion developed to protect vulnerable kinships, hormones such as oxytocin, which have been suggested as playing a key role in ‘tend-and-befriend’ behaviors among women, will enhance compassion toward women but not toward men. Thirty subjects participated in a double-blind, placebo-controlled, within-subject study. Following administration of oxytocin/placebo, participants listened to recordings of different female/male protagonists describing distressful emotional conflicts and were then asked to provide compassionate advice to the protagonist. The participants’ responses were coded according to various components of compassion by two clinical psychologists who were blind to the treatment. The results showed that in women and men participants oxytocin enhanced compassion toward women, but did not affect compassion toward men. These findings indicate that the oxytocinergic system differentially mediates compassion toward women and toward men, emphasizing an evolutionary perspective that views compassion as a caregiving behavior designed to help vulnerable individuals.

2016-10-01

Attitudes to ageing exert a powerful influence on health and well-being, yet surprisingly little research has examined factors that contribute to the formation of these attitudes. The aim of this study was to consider the potential role of self-compassion in predicting attitudes to ageing, which in turn contribute to positive and negative mental well-being and self-reported health. This was a cross-sectional study using data from 517 midlife women aged between 40 and 60. Structural equation modelling was used to examine the relationships between self-compassion, three facets of attitudes to ageing and well-being outcomes. Together, self-compassion and attitudes to ageing explained between 36% and 67% of the variance in well-being. Self-compassion was a strong predictor of attitudes towards psychosocial loss, physical change and psychological growth (β range: .22-.51). Furthermore, the relationship between self-compassion and well-being outcomes was partially mediated by attitudes to physical change. Self-compassion may be a modifiable internal resource to promote healthy attitudes to ageing in midlife, when ageing becomes personally relevant. Moreover, attitudes towards physical change may help explain how self-compassion promotes well-being among midlife women.

Attachment and compassion fatigue among American and Israeli mental health clinicians working with traumatized victims of terrorism.

PubMed

Racanelli, Christine

2005-01-01

This study compared the construct of compassion fatigue with the role of attachment as a potential mediator among mental health clinicians working with victims of terrorism in the New York metropolitan region of the United States and Israel. Differences between clinicians practicing within Israel (n = 31) and New York (n = 35), in terms of their symptoms of compassion fatigue, compassion satisfaction, and "burnout," were not significant, as measured by multivariate analyses of variance. Based upon nonsignificant differences, mediational statistical tests could not be run; thus, mediation did not hold. The data failed to support a significant difference between compassion fatigue and attachment avoidance or anxiety. However, data collection resulted in attenuated scores for compassion fatigue and compassion satisfaction within both study groups of clinicians and moderate to average scores for burnout. Israeli clinicians had significantly more avoidant attachment dimensions than their New York cohorts. The strongest predictors of compassion satisfaction were (a) low attachment anxiety and (b) sufficient clinical experience related to treating victims of trauma. The strongest predictors of burnout were (a) minimal clinical experience, (b) minimal experience working with trauma victims, and (c) greater avoidant attachment dimensions.

Compassion fatigue and burnout among Rabbis working as chaplains.

2006-01-01

Compassion Fatigue, Compassion Satisfaction, and Burnout were studied in a convenience sample of 66 male and female Rabbis who work as chaplains and attended the annual conference of the National Association of Jewish Chaplains (NAJC) in 2002. Although Compassion Fatigue and Burnout were low among the survey participants, both measures were significantly higher among the women in the sample. Compassion Fatigue was also higher among chaplains who were divorced, and it increased with the number of hours per week the chaplains spent working with trauma victims or their families (r = .25, p<.05). Hierarchical multiple regression was performed to determine the influence of six professional and five personal variables on each of the three dependent variables. Four professional variables accounted for 19.5% of the variation and three personal variables accounted for 20.3% of the variation in Compassion Fatigue. Attempts to predict Burnout and Compassion Satisfaction were far less successful. Burnout was predicted by only two variables (i.e. age and years as a Rabbi), which accounted for just 18.4% of the variance in Burnout scores. Age was the only variable found to have a significant effect on Compassion Satisfaction, and its effect was positive. The implications of the findings are discussed.

Self-compassion has demonstrated many psychological benefits (Neff, 2009). In an effort to explore self-compassion as a potential resource for young women athletes, we explored relations among self-compassion, proneness to self-conscious emotions (i.e., shame, guilt-free shame, guilt, shame-free guilt, authentic pride, and hubristic pride), and potentially unhealthy self-evaluative thoughts and behaviors (i.e., social physique anxiety, obligatory exercise, objectified body consciousness, fear of failure, and fear of negative evaluation). Young women athletes (N = 151; Mage = 15.1 years) participated in this study. Self-compassion was negatively related to shame proneness, guilt-free shame proneness, social physique anxiety, objectified body consciousness, fear of failure, and fear of negative evaluation. In support of theoretical propositions, self-compassion explained variance beyond self-esteem on shame proneness, guilt-free shame proneness, shame-free guilt proneness, objectified body consciousness, fear of failure, and fear of negative evaluation. Results suggest that, in addition to self-esteem promotion, self-compassion development may be beneficial in cultivating positive sport experiences for young women.

Cognitions as mediators in the relationship between self-compassion and affect

Previous studies suggest that self-compassion is related to numerous facets of mental health, but the role of cognitions in this relationship remains unknown. To examine the mediating role of cognitions in the relationship between self-compassion and anxiety, depression, and life satisfaction when controlling for self-esteem in Japanese people, we conducted two studies. Study 1 (N = 231) examined the relationship between self-compassion and affect by modeling negative automatic thoughts as a mediator; Study 2 (N = 233) tested whether positive and negative automatic thoughts meditate this relationship. Results suggested that both self-compassion and self-esteem increased positive automatic thoughts and decreased trait anxiety, whereas only self-esteem increased life satisfaction and decreased depression directly. Positive automatic thoughts increased life satisfaction and decreased depression and trait anxiety, and positive automatic thoughts mediated the relationship between self-compassion and negative affect. These findings suggest that both positive and negative automatic thoughts mediate the relationship between self-compassion and affect in Japanese people. PMID:25395717

Emotion Regulation Strategies, Secondary Traumatic Stress, and Compassion Satisfaction in Healthcare Providers.

PubMed

Măirean, Cornelia

2016-11-16

The aim of the present study is to examine the relationships between two emotion regulation strategies (cognitive reappraisal and expressive suppression), secondary traumatic stress, and compassion satisfaction in a sample of 190 healthcare providers. Another aim of this study is to examine if the relations between emotion regulation strategies and traumatic stress symptoms are moderated by compassion satisfaction. The respondents volunteered to take part in the research and completed self-reporting measures describing the use of emotional regulation strategies, the symptoms of secondary traumatic stress, and the compassion satisfaction. The results revealed negative associations between cognitive reappraisal and secondary traumatic stress, while expressive suppression is positively associated with arousal. Moreover, cognitive reappraisal is positively related to compassion satisfaction, while secondary traumatic stress symptoms are negatively correlated with compassion satisfaction. Furthermore, the relationship between expressive suppression and intrusions is moderated by compassion satisfaction. The implications of these results for enhancing professional quality of life in the context of secondary exposure to traumatic life events are discussed.

Self-compassion has been framed as a healthy alternative to self-esteem, as it is nonevaluative. However, rather than being alternatives, it may be that the two constructs develop in a mutually reinforcing way. The present study tested this possibility among adolescents. A large adolescent sample (N = 2,809; 49.8% female) reported levels of trait self-esteem and self-compassion annually for 4 years. Autoregressive cross-lagged structural equation models were used to estimate the reciprocal longitudinal relations between the two constructs. Self-esteem consistently predicted changes in self-compassion across the 4 years of the study, but not vice versa. Self-esteem appears to be an important antecedent of the development of self-compassion, perhaps because the capacity to extend compassion toward the self depends on one's appraisals of worthiness. These findings add important insights to our theoretical understanding of the development of self-compassion. © 2017 Wiley Periodicals, Inc.

Self-Compassion Promotes Personal Improvement From Regret Experiences via Acceptance.

PubMed

Zhang, Jia Wei; Chen, Serena

2016-02-01

Why do some people report more personal improvement from their regret experiences than others? Three studies examined whether self-compassion promotes personal improvement derived from recalled regret experiences. In Study 1, we coded anonymous regret descriptions posted on a blog website. People who spontaneously described their regret with greater self-compassion were also judged as having expressed more personal improvement. In Study 2, higher trait self-compassion predicted greater self-reported and observer-rated personal improvement derived from recalled regret experiences. In Study 3, people induced to take a self-compassionate perspective toward a recalled regret experience reported greater acceptance, forgiveness, and personal improvement. A multiple mediation analysis comparing acceptance and forgiveness showed self-compassion led to greater personal improvement, in part, through heightened acceptance. Furthermore, self-compassion's effects on personal improvement were distinct from self-esteem and were not explained by adaptive emotional responses. Overall, the results suggest that self-compassion spurs positive adjustment in the face of regrets. © 2015 by the Society for Personality and Social Psychology, Inc.

Previous research indicates that lower-class individuals experience elevated negative emotions as compared with their upper-class counterparts. We examine how the environments of lower-class individuals can also promote greater compassionate responding-that is, concern for the suffering or well-being of others. In the present research, we investigate class-based differences in dispositional compassion and its activation in situations wherein others are suffering. Across studies, relative to their upper-class counterparts, lower-class individuals reported elevated dispositional compassion (Study 1), as well as greater self-reported compassion during a compassion-inducing video (Study 2) and for another person during a social interaction (Study 3). Lower-class individuals also exhibited heart rate deceleration-a physiological response associated with orienting to the social environment and engaging with others-during the compassion-inducing video (Study 2). We discuss a potential mechanism of class-based influences on compassion, whereby lower-class individuals' are more attuned to others' distress, relative to their upper-class counterparts.

This study aimed to identify relationships between compassion fatigue, burnout, and turnover intention in Korean hospital nurses. In total, 142 hospital nurses were surveyed as part of data collection. Data related to compassion fatigue, burnout, and turnover intention were collected using a questionnaire between May 2011 and September 2011. The data analysis was performed using PASW 19.0 program, which included one-way ANOVA, independent t-tests, Pearson's correlation coefficient, and hierarchical regression analysis. This study detected a positive correlation between compassion fatigue and burnout(r=.37, p<.001), and turnover intention(r=.55, p<.001). Compassion fatigue accounted for 29.6% of the variance for turnover intention among Korean hospital nurses. The results indicate that it is necessary to reduce compassion fatigue, and turnover intention among Korean hospital nurses.

Gentry, J Eric; Baggerly, Jennifer; Baranowsky, Anna

2004-01-01

Mental health and other service professionals who work with trauma survivors often experience the debilitating effects of compassion fatigue and caregiver stress. Leaders within the field have called for effective, empirically supported interventions for professionals who experience these negative effects. In response to the call, this study examines the treatment effectiveness of the Certified Compassion Fatigue Specialist Training (CCFST) for 83 participating mental health professionals. Results show a statistically and clinically significant decrease in participants' compassion fatigue and burnout symptoms and increase in their compassion satisfaction. A "training-as-treatment" effect of CCFST is introduced, described, and evaluated. Discussion of these findings, clinical implications, limitations, and future directions are provided. CCFST appears to be an effective intervention for ameliorating compassion fatigue symptoms in mental health professionals.

These programs are designed to foster a diverse, collaborative student community in which students engage in authentic research practices and regular self-reflection. Graduate students, together with upper-level undergraduates, design and run all Compass programs. Compass strives to incorporate best practices from the science education literature. Experiences in Compass leave participants poised to be successful students researchers, teachers, and mentors.

Imagining the Unimaginable

This article explores the ways in which parricide was comprehended in England and Wales, c.1600–1760, and shows that while some parallels exist with modern explanatory models of parricide offenders, they had very different meanings in the early modern context. While both lunacy and the cruelty of parents were understood as possible contexts for parricide, neither were common. The dominant explanation was the gratuitous violence of a selfish individual who lacked compassion and who saw the parent as an obstacle—to an inheritance, riches, marriage, and freedom—to be removed. The article explores these three categories and suggests ways in which this began to change in the mid-eighteenth century. PMID:27365565

[Compassion as a mediator between stressful events and perceived stress in Greek students].

PubMed

Tholouli, E; Maridaki-Kassotaki, A; Varvogli, L; Chrousos, G P

2016-01-01

Compassion is closely related with human's survival as a mammal and has been developed through evolution for pain reduction, for forming affiliative bonds and alliances with non kin in order to increase protection and cope with external threats. Compassion seems to influence people's ability to deal with life's adverse situations such as stress and it is linked with lower psychopathology and greater wellbeing. Compassion is closely related to empathy and altruism and it is defined as the recognition of the pain of the self or others' that is accompanied with the will to take action in order to relieve the person from pain. Its main features are kindness instead of self-judgment and indifference, the recognition of common humanity instead of the feeling of separation and mindfulness when facing adverse conditions instead of over-identification with one's pain or disengagement with the pain of others. According to the biopsychosocial approach, stress can be defined by three dimensions such as the cause or stressful factors that can be major life events or daily hassles, the perception of stress that is manifested through cognitive, emotional and behavioural reactions and the physiological response for achieving homeostasis. The purpose of the present study was to investigate the role of compassion for self and others in the occurrence of stressful events and levels of perceived stress in students. Participants were 280 undergraduate students from two Greek universities. Results indicated that students who had experienced a greater amount of stressful events during the past year reported having higher levels of perceived stress and that higher self-compassion was correlated with less perceived stress. Moreover, the adverse effect of stressful events on perceived stress was partially explained by the mediating role of self-compassion. Students who reported more stressful events showed higher compassion for others in opposition to compassion towards themselves but compassion for others was not significantly correlated with perceived stress. Since compassion is not considered being a fixed personality trait but it is seen as a capacity that can be developed by appropriate training it was suggested that enhancing self-compassion's stress buffering properties can be useful for dealing with stressful events and reducing stress responses. Moeover, it was suggested that it is interesting to explore the relationship between compassion for others and positive characteristics such as sense of coherence, quality of life and social support that may enhance stress resilience indirectly. The above findings imply that it is important to investigate further the role of compassion in coping with stress in qualitative, longitudinal studies as well as randomized control trials. Compassion may be an alternative mechanism for coping with stressful events and stress, other than fight or flight that has been shaped by evolution.

The linkages among childhood maltreatment, adolescent mental health, and self-compassion in child welfare adolescents.

Tanaka, Masako; Wekerle, Christine; Schmuck, Mary Lou; Paglia-Boak, Angela

2011-10-01

Childhood maltreatment is a robust risk factor for poor physical and mental health. Child welfare youths represent a high-risk group, given the greater likelihood of severe or multiple types of maltreatment. This study examined the relationship between childhood maltreatment and self-compassion - a concept of positive acceptance of self. While not applied previously to a child welfare sample, self-compassion may be of value in understanding impairment among maltreatment victims. This may be most pertinent in adolescence and young adulthood, when self-identity is a focal developmental process. The present sample was drawn from the Maltreatment and Adolescent Pathways (MAP) Longitudinal Study, which followed randomly selected adolescents receiving child protection services across two years within an urban catchment area. Child maltreatment was assessed at baseline using the Childhood Trauma Questionnaire (Bernstein et al., 1994, 2003). Mental health, substance and alcohol use problems, suicide attempt, and self-compassion were assessed at the two-year follow-up point. There were 117 youths, aged 16-20 years (45.3% males) who completed the self-compassion scale (Neff, 2003). Bivariate correlations were computed between adolescent self-compassion and each form of self-reported maltreatment (physical abuse, sexual abuse, emotional abuse, emotional neglect, and physical neglect). Finally, hierarchical, stepwise regression was used to examine unique contributions of child maltreatment subtypes in predicting adolescent self-compassion, as well as maltreatment-related impairment. Higher childhood emotional abuse, emotional neglect, and physical abuse were associated with lower self-compassion. Controlling for age and gender, emotional abuse was significantly associated with reduced self-compassion, even when the effects of emotional neglect and physical abuse were taken into account. Youths with low self-compassion were more likely to have psychological distress, problem alcohol use, and report a serious suicide attempt, as compared with those with high self-compassion. A number of maltreatment-related areas of impairment, identified by screening instruments, were significantly associated with lower self-compassion. Self-compassion may be a fruitful aspect of research to pursue in an effort to better understand the impact of childhood emotional abuse on adolescent functioning, particularly considering the under-researched group of those receiving child protective services.

Community mental health nurses' and compassion: an interpretative approach.

PubMed

Barron, K; Deery, R; Sloan, G

2017-05-01

WHAT IS KNOWN ON THE SUBJECT?: The concept of compassion is well documented in the healthcare literature but has received limited attention in mental health nursing. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Mental health nurses struggle with defining compassion. The study, with its limitations, brings greater clarity to the meaning of compassion for community mental health nurses and NHS organizations. Mental health nurses need time to reflect on their provision of compassionate care. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The study has shown that compassion is important for NHS healthcare management, frontline mental health nurses and policy-makers in UK, and there is potential for sharing practice and vision across NHS organisations. Mental health nurses could benefit from training to facilitate their understanding of compassionate practices. Emphasis should be placed on the importance of self-compassion and how this can be nurtured from the secure base of clinical supervision. Introduction There is increasing emphasis in policy, research and practice in the UK and internationally on the importance of caring in health care. Compassion needs to be at the core of all healthcare professionals' practice. Recently, health care has received negative attention through media and government reports which cite a lack of compassion in care. Rationale The concept of compassion has received limited attention in community mental health nursing. Aim Based on data taken from semi-structured interviews with community mental health nurses, this paper aims to describe interpretations and perspectives of compassion to gain insight and development of its meaning. Method A naturalistic, interpretive approach was taken to the study. Semi-structured interviews with nine mental health nurses were analysed using Burnard's 14-step model of thematic analysis. Findings The research illuminates the complexity of compassion and how its practice impacts on emotional responses and relationships with self, patients, colleagues and the employing organization. Participants identified difficulties engaging with compassionate practice whilst recognizing it as a driving force underpinning provision of care. Implications for practice Mental health nurses need to be supported to work towards a greater understanding of compassionate care for clinical practice and the need for self-compassion. © 2017 John Wiley & Sons Ltd.

Mindfulness of voices, self-compassion, and secure attachment in relation to the experience of hearing voices.

Dudley, James; Eames, Catrin; Mulligan, John; Fisher, Naomi

Developing compassion towards oneself has been linked to improvement in many areas of psychological well-being, including psychosis. Furthermore, developing a non-judgemental, accepting way of relating to voices is associated with lower levels of distress for people who hear voices. These factors have also been associated with secure attachment. This study explores associations between the constructs of mindfulness of voices, self-compassion, and distress from hearing voices and how secure attachment style related to each of these variables. Cross-sectional online. One hundred and twenty-eight people (73% female; M age  = 37.5; 87.5% Caucasian) who currently hear voices completed the Self-Compassion Scale, Southampton Mindfulness of Voices Questionnaire, Relationships Questionnaire, and Hamilton Programme for Schizophrenia Voices Questionnaire. Results showed that mindfulness of voices mediated the relationship between self-compassion and severity of voices, and self-compassion mediated the relationship between mindfulness of voices and severity of voices. Self-compassion and mindfulness of voices were significantly positively correlated with each other and negatively correlated with distress and severity of voices. Mindful relation to voices and self-compassion are associated with reduced distress and severity of voices, which supports the proposed potential benefits of mindful relating to voices and self-compassion as therapeutic skills for people experiencing distress by voice hearing. Greater self-compassion and mindfulness of voices were significantly associated with less distress from voices. These findings support theory underlining compassionate mind training. Mindfulness of voices mediated the relationship between self-compassion and distress from voices, indicating a synergistic relationship between the constructs. Although the current findings do not give a direction of causation, consideration is given to the potential impact of mindful and compassionate approaches to voices. © 2017 The Authors.

2018-03-01

To report the findings from an evaluation of the impact of the Compassion in Practice Vision and Strategy (National Health Service England (NHSE), 2012) on nursing, midwifery and care staff. The Compassion in Practice Vision and Strategy was a programme of work to highlight the importance of compassionate care following the Francis Report in 2013 into the deficits in care in an NHS Hospital Trust. It was launched by NHS England in 2012 at a time when fiscal cuts were introduced by the Department of Health in England. Mixed methods. Inferential statistics were used to test whether there were significant differences between staff at different levels of seniority with regard to awareness and involvement in Compassion in Practice Vision and Strategy and their attitudes to it. Awareness and involvement of staff in Compassion in Practice Vision and Strategy were high amongst middle and senior management but limited at ward level. Staff involvement in Compassion in Practice Vision and Strategy was limited due to a lack of awareness. Ward level staff who were aware and involved, perceived a lack of support and communication from senior leadership to deliver the Compassion in Practice Vision and Strategy. Results reveal professional anger, distress and resistance to the Compassion in Practice Vision and Strategy and a view of the programme as a top-down initiative which did not sufficiently recognise structural constraints on nurses' ability to deliver compassionate care. We discuss the implications of our findings for global nursing. Participants emphasised that compassion for patients is only sustainable where there is compassion for staff and many participants felt that they were not being treated with compassion. National Health Service England should strongly affirm that nurses and midwives in general provide compassionate care. Trust leadership should provide support for ward level staff who deliver compassionate care in difficult circumstances. © 2017 John Wiley & Sons Ltd.

Lung cancer patients and their spouses report high rates of distress. Due to the increasing popularity of and evidence for mindfulness-based interventions in cancer, mindfulness and self-compassion have been identified as potentially helpful skills when coping with cancer. This dyadic study examined how mindfulness and self-compassion are related to psychological distress and communication about cancer in couples facing lung cancer. Using the actor-partner interdependence model, self-reported mindfulness, self-compassion, psychological distress and communication about cancer were analyzed in a cross-sectional sample of 88 couples facing lung cancer. Regarding psychological distress, no difference was found between patients and spouses. In both partners, own levels of mindfulness ( B  = -0.19, p  = .002) and self-compassion ( B  = -0.45, p  < .001) were negatively related to own distress levels. At a dyadic level, own self-compassion was less strongly associated with distress if the partner reported high self-compassion ( B  = 0.03, p  = .049). Regarding communication about cancer, patients reported to communicate more openly with their partner than with spouses. However, after controlling for gender, this difference was no longer significant. In both partners, own self-compassion ( B  = 0.03, p  = .010) was significantly associated with own communication while mindfulness was not. A trend showed that mindfulness of the partner was related to more open communication in the individual ( B  = 0.01, p  = .080). These findings give a first indication that mindfulness and self-compassion skills may go beyond the individual and could impact couple functioning. Future research should examine whether couples facing (lung) cancer may benefit from programs in which mindfulness and self-compassion are cultivated.

The Cost of Caring: An Exploration of Compassion Fatigue, Compassion Satisfaction, and Job Satisfaction in Pediatric Nurses.

PubMed

Roney, Linda Nancy; Acri, Mary C

The purpose of this study was to describe levels of compassion satisfaction, compassion fatigue, and job satisfaction among pediatric nurses in the United States and determine if there was a relationship among these constructs. All members Society of Pediatric Nurses were sent an electronic invitation to participate, and those who consented received three measures; a demographic questionnaire, the Job Satisfaction Survey (JSS) and the Professional Quality of Life (ProQOL) measure. Three hundred eighteen (10.6%) of members of the Society of Pediatric Nurses participated in the study: Over three quarters (245, 76%) of the sample had another career before nursing. The sample's mean job satisfaction level was 149.8 (SD=29.74), which was significantly higher than published reported means for nurses. Bivariate analyses revealed a significant relationship between gender and the compassion satisfaction, in that women were more likely to evidence compassion satisfaction than men (t=1.967, p=.05, df=298). No other significant relationships were found. The majority of nurses had high levels of compassion satisfaction and job satisfaction; further, female gender was associated with higher levels of compassion satisfaction. This current study had a very high response from second-career nurses (n=245, 76.8%) and overall, the sample had higher levels of compassion satisfaction. It is possible that second career nurses are better equipped in some way that helps them mediate negative responses of caring as a pediatric nurse and future research should explore this. Due to the significant financial costs to institutions of having nurses who have low levels of job satisfaction and high levels on compassion fatigue, it is imperative for hospital administrators to develop infrastructures to support employees.

Atkinson, David M; Rodman, John L; Thuras, Paul D; Shiroma, Paulo R; Lim, Kelvin O

2017-07-01

Burnout, a state of emotional exhaustion associated with negative personal and occupational outcomes, is prevalent among healthcare providers. A better understanding of the psychological factors that may be associated with resilience to burnout is essential to develop effective interventions. Self-compassion, which includes kindness toward oneself, recognition of suffering as part of shared human experience, mindfulness, and nonjudgment toward inadequacies and failures, may be one such factor. The purpose of this study was to examine the relationships between burnout, depression, and self-compassion in Veterans Affairs (VA) mental health staff. Cross-sectional study. VA medical center and affiliated community-based clinics. VA mental health staff. The 19-item Copenhagen Burnout Inventory, the 26-item Self-Compassion Scale, and the Patient Health Questionnaire 2-item depression screen. Demographic information included age, sex, years worked in current position, and number of staff supervised. One hundred and twenty-eight of a potential 379 individuals (33.8%) responded. Clerical support, nursing, social work, psychology, and psychiatry were the major professions represented. Self-compassion was inversely correlated with burnout (r = -0.41, p < 0.001), and inversely correlated with depression (r pb  = -0.39, p < 0.001). The inverse relationship between self-compassion and burnout remained significant even after accounting for depressive symptoms and demographic variables in a multiple linear regression model. Of all the variables examined, self-compassion was the strongest predictor of burnout. The results of this study support the hypothesis that self-compassion may be associated with resilience to burnout. Alternatively, decreased self-compassion may be a downstream effect of increased burnout. Prospective, longitudinal studies are needed to determine the directional relationship between these factors, and whether interventions that cultivate self-compassion may decrease burnout and/or protect against its negative personal and professional outcomes.

2017-03-01

The current study sought to assess the acceptability and feasibility of a compassion-focused therapy (CFT) group as an adjunct to evidence-based outpatient treatment for eating disorders, and to examine its preliminary efficacy relative to treatment as usual (TAU). Twenty-two outpatients with various types of eating disorders were randomly assigned to 12 weeks of TAU (n = 11) or TAU plus weekly CFT groups adapted for an eating disorder population (CFT + TAU; n = 11). Participants in both conditions completed measures of self-compassion, fears of compassion, shame and eating disorder pathology at baseline, week 4, week 8 and week 12. Additionally, participants receiving the CFT group completed measures assessing acceptability and feasibility of the group. Results indicated that the CFT group demonstrated strong acceptability; attendance was high and the group retained over 80% of participants. Participants rated the group positively and indicated they would be very likely to recommend it to peers with similar symptoms. Intention-to-treat analyses revealed that compared to the TAU condition, the CFT + TAU condition yielded greater improvements in self-compassion, fears of self-compassion, fears of receiving compassion, shame and eating disorder pathology over the 12 weeks. Results suggest that group-based CFT, offered in conjunction with evidence-based outpatient TAU for eating disorders, may be an acceptable, feasible and efficacious intervention. Furthermore, eating disorder patients appear to see benefit in, and observe gains from, working on the CFT goals of overcoming fears of compassion, developing more self-compassion and accessing more compassion from others.

Self-compassion in the face of shame and body image dissatisfaction: implications for eating disorders.

PubMed

Ferreira, Cláudia; Pinto-Gouveia, José; Duarte, Cristiana

2013-04-01

The current study examines the role of self-compassion in face of shame and body image dissatisfaction, in 102 female eating disorders' patients, and 123 women from general population. Self-compassion was negatively associated with external shame, general psychopathology, and eating disorders' symptomatology. In women from the general population increased external shame predicted drive for thinness partially through lower self-compassion; also, body image dissatisfaction directly predicted drive for thinness. However, in the patients' sample increased shame and body image dissatisfaction predicted increased drive for thinness through decreased self-compassion. These results highlight the importance of the affiliative emotion dimensions of self-compassion in face of external shame, body image dissatisfaction and drive for thinness, emphasising the relevance of cultivating a self-compassionate relationship in eating disorders' patients.

Stress can have detrimental effects on nurse residents' levels of job satisfaction, compassion, fatigue, and burnout. This can lead to high turnover rates and poor quality of care among novice nurses. Therefore, it is critical to identify protective factors to prevent the onset of negative nurse outcomes (compassion fatigue, burnout, and job dissatisfaction) and to promote positive nurse outcomes (job satisfaction, compassion satisfaction). This study aimed to determine whether factors such as group cohesion and organizational commitment would be protective and moderate the association between stress exposure and posttraumatic stress symptoms and other negative nurse outcomes, thus facilitating positive outcomes. Findings showed that group cohesion was effective in moderating the negative effects of current stress exposure and posttraumatic stress symptoms on negative nurse outcomes, specifically on increased compassion fatigue and burnout, and reduced compassion satisfaction. In addition, organizational commitment was determined to promote positive nurse outcomes such as job satisfaction and compassion satisfaction. The study findings are promising, as retention of quality nurses is a significant problem for hospitals. Nurse managers and hospital administrators should be aware of the benefits of group cohesion and organizational commitment and strive to make the promotion of these factors a priority.

COMPASS time synchronization and dissemination—Toward centimetre positioning accuracy

NASA Astrophysics Data System (ADS)

Wang, ZhengBo; Zhao, Lu; Wang, ShiGuang; Zhang, JianWei; Wang, Bo; Wang, LiJun

2014-09-01

In this paper we investigate methods to achieve highly accurate time synchronization among the satellites of the COMPASS global navigation satellite system (GNSS). Owing to the special design of COMPASS which implements several geo-stationary satellites (GEO), time synchronization can be highly accurate via microwave links between ground stations to the GEO satellites. Serving as space-borne relay stations, the GEO satellites can further disseminate time and frequency signals to other satellites such as the inclined geo-synchronous (IGSO) and mid-earth orbit (MEO) satellites within the system. It is shown that, because of the accuracy in clock synchronization, the theoretical accuracy of COMPASS positioning and navigation will surpass that of the GPS. In addition, the COMPASS system can function with its entire positioning, navigation, and time-dissemination services even without the ground link, thus making it much more robust and secure. We further show that time dissemination using the COMPASS-GEO satellites to earth-fixed stations can achieve very high accuracy, to reach 100 ps in time dissemination and 3 cm in positioning accuracy, respectively. In this paper, we also analyze two feasible synchronization plans. All special and general relativistic effects related to COMPASS clocks frequency and time shifts are given. We conclude that COMPASS can reach centimeter-level positioning accuracy and discuss potential applications.

What is compassion and how can we measure it? A review of definitions and measures.

2016-07-01

The importance of compassion is widely recognized and it is receiving increasing research attention. Yet, there is lack of consensus on definition and a paucity of psychometrically robust measures of this construct. Without an agreed definition and adequate measures, we cannot study compassion, measure compassion or evaluate whether interventions designed to enhance compassion are effective. In response, this paper proposes a definition of compassion and offers a systematic review of self- and observer-rated measures. Following consolidation of existing definitions, we propose that compassion consists of five elements: recognizing suffering, understanding the universality of human suffering, feeling for the person suffering, tolerating uncomfortable feelings, and motivation to act/acting to alleviate suffering. Three databases were searched (Web of Science, PsycInfo, and Medline) and nine measures included and rated for quality. Quality ratings ranged from 2 to 7 out of 14 with low ratings due to poor internal consistency for subscales, insufficient evidence for factor structure and/or failure to examine floor/ceiling effects, test-retest reliability, and discriminant validity. We call our five-element definition, and if supported, the development of a measure of compassion based on this operational definition, and which demonstrates adequate psychometric properties.

The RICH detector of AMS-02: 5 years of operation in space

NASA Astrophysics Data System (ADS)

Liu, Hu; Casaus, J.; Giovacchini, F.; Oliva, A.; Xia, X.; AMS02-RICH Collaboration

2017-12-01

AMS-02 is a high-energy particle physics magnetic spectrometer installed on the International Space Station since May 2011, and operating continuously since then. The AMS-02 Ring Imaging Čerenkov counter (RICH) is a specialised sub-detector for the precise measurement of the particle velocity β with a resolution of Δβ / β = 0.7 (2.4) ×10-3 for helium nuclei passing through the Aerogel (NaF) radiator. From the emitted photon counting the particle absolute charge magnitude | Z | can be estimated with an uncertainty of 0.3 charge units for helium nuclei. In 5 years of operations the optical properties of the RICH had no significant degradation and the performances of the detector have been stable in time. By means of the simultaneous use of the Silicon Tracker and the RICH, AMS is able to investigate the isotopic composition of cosmic rays in the kinetic energy range from few GeV/n to ∼10 GeV/n for elements with charge | Z | up to 4 with unprecedented statistics. The precise measurement of cosmic rays light nuclei isotopes ratio, such as 3He/4He and 10Be/9Be, provide important constraints to the free parameters in the models for cosmic rays propagation in our Galaxy. In particular the mass distinction between 3He and 4He needed for the measurement of the 3He/4He flux ratio is obtained by statistical methods. The excellent simulation of the AMS detector provides the precise description needed for this analysis. Moreover, the use of the geomagnetic field for selecting control samples of CRs with enhanced abundances of heavy isotopes provides an independent tool for the study of the light nuclei isotopic composition with AMS.

Compassion fatigue in nursing has been shown to impact the quality of patient care and employee satisfaction and engagement. The aims of this study were to determine the prevalence and severity of compassion fatigue among pediatric nurses and variations in prevalence based on respondent demographics using a cross-sectional survey design. Nurses under 40 years of age, with 6-10 years of experience and/or working in a medical-surgical unit had significantly lower compassion satisfaction and higher levels of burnout. Secondary traumatic stress from caring for children with severe illness or injury or end of life was a key contributor to compassion fatigue. Copyright © 2015 Elsevier Inc. All rights reserved.

The saving of time that results from flying across country on compass headings is beginning to be widely recognized. At the same time the general use of steel tube fuselages has made a knowledge of compass correction much more necessary than was the case when wooden fuselages were the rule. This paper has been prepared primarily for the benefit of the pilot who has never studied navigation and who does not desire to go into the subject more deeply than to be able to fly compass courses with confidence. It also contains material for the designer who wishes to install his compasses with the expectation that they may be accurately corrected.

Compassion Fatigue and Mindfulness: Comparing Mental Health Professionals and MSW Student Interns.

2017-01-01

The relationship between compassion fatigue and mindfulness in mental health professionals compared to Master of Social Work (MSW) students is explored. A convenience sample of mental health professionals (n = 40) and MSW students (n = 111) completed the Five Facet Mindfulness Questionnaire and Professional Quality of Life Scale. Results indicate a medium, negative correlation between compassion fatigue and mindfulness, with high levels of compassion fatigue associated with lower levels of mindfulness. There was no statistically significant difference between mental health workers and MSW students on the combined dependent variables. Results suggest that mindfulness protects against compassion fatigue regardless of professional or student status.

2017-01-01

As adolescence can be a stressful developmental stage, the purpose of this study was to determine if a novel mindful self-compassion program would decrease stress, depressive symptoms, and anxiety and increase resilience, gratitude, and curiosity/exploration (positive risk-taking), and to ascertain if mindfulness and self-compassion co-varied with these outcomes over time. Forty-seven adolescents in the southeast U.S. enrolled in an 8-week mindful self-compassion course in five cohorts. Measures were assessed at pre-intervention, post-intervention, and 6-week follow-up. Multilevel growth analyses revealed main effects of time on perceived stress, resilience, curiosity/exploration and gratitude. Additionally, both mindfulness and self-compassion co-varied with perceived stress and depressive symptoms; mindfulness also co-varied with anxiety and self-compassion co-varied with resilience and curiosity/exploration. Implications of these findings are that this program has potential in decreasing stress and increasing resilience and positive risk-taking. Future studies with a control group need to be conducted to confirm these findings. PMID:28414965

Protective Effect of Self-Compassion to Emotional Response among Students with Chronic Academic Stress

2016-01-01

The literature has shown that self-compassion is a protective factor of an individual’s emotional response to chronic stress. However, this stress-buffering effect has not been completely analyzed in individuals who report significantly high academic stress. The present study explored the role of self-compassion in a group of undergraduate students who experience chronic academic stress. A total of 208 undergraduate students who were preparing for the Postgraduate Entrance Examination (PEE) were recruited and completed the Self-Compassion Scale, Adolescent Self-Rating Life Event Check List, and Positive and Negative Affect Schedule. Differences analysis confirmed that the participants reported significantly higher academic stress than their peers who were not preparing for PEE. Self-compassion positively related to positive affect but negatively related to negative affect and learning stress. Further analysis showed that self-compassion negatively mediated the relationship between chronic academic stress and negative affect. Findings imply that self-compassion-centered interventions can be developed in the educational context to assist students cope with chronic academic stress. PMID:27920736

"Tu Souffres, Cela Suffit": the compassionate hospital.

PubMed

Kearsley, John H; Youngson, Robin

2012-04-01

The authors propose that the characteristics of personal (individual) compassion may be extrapolated to the concept of corporate (organizational) compassion. Modern health care facilities attract staff members who are able to exercise varying degrees of compassion in their busy daily routines. However, little discussion has taken place on how health care organizations might best harness and integrate aspects of individual compassion to create an organization with compassion as a core value. We define three characteristics of a "compassionate hospital" as 1) the presence of a healing environment, 2) a sense of connection among people, and 3) a sense of purpose and identity. We suggest how a "top down" focus on compassion as a core value by clinical leaders could maximize the compassion of health care workers, and reduce the suffering expressed and/or experienced by health care workers and patients in today's health care facilities. The compassionate hospital concept is intended to act as a proposition for health policy researchers and decision-makers in health care so as to reduce the suffering of sick patients, and to restore a sense of well-being, meaning, and purpose among health care workers.

Toward a comprehensive, theoretical model of compassion fatigue: An integrative literature review.

PubMed

Coetzee, Siedine K; Laschinger, Heather K S

2018-03-01

This study was an integrative literature review in relation to compassion fatigue models, appraising these models, and developing a comprehensive theoretical model of compassion fatigue. A systematic search on PubMed, EbscoHost (Academic Search Premier, E-Journals, Medline, PsycINFO, Health Source Nursing/Academic Edition, CINAHL, MasterFILE Premier and Health Source Consumer Edition), gray literature, and manual searches of included reference lists was conducted in 2016. The studies (n = 11) were analyzed, and the strengths and limitations of the compassion fatigue models identified. We further built on these models through the application of the conservation of resources theory and the social neuroscience of empathy. The compassion fatigue model shows that it is not empathy that puts nurses at risk of developing compassion fatigue, but rather a lack of resources, inadequate positive feedback, and the nurse's response to personal distress. By acting on these three aspects, the risk of developing compassion fatigue can be addressed, which could improve the retention of a compassionate and committed nurse workforce. © 2017 John Wiley & Sons Australia, Ltd.

2015-07-01

Emerging research suggests that low self-compassion may be linked to psychopathology and in particular depressive symptoms. To further elucidate this topic, the present study investigated self-compassion in patients with Bipolar Disorder (BD). Thirty remitted BD patients were compared to thirty age- and sex matched controls on the Self-Compassion Scale (SCS). The BD patients also completed the Altman Self-Rating Mania Scale (ASRM), the Major Depression Inventory (MDI), the Work and Social Adjustment Scale (WSAS), the Satisfaction With Life Scale (SWLS) and the Internalized Stigma of Mental Illness Scale (ISMI-10) and further reported their illness history on a survey sheet. The BD patients were found to have significantly lower self-compassion than controls. In addition, self-compassion correlated positively and significantly with life-satisfaction but no significant correlations with functional impairment, internalized stigma or frequency of past affective episodes were found. The small sample size entailed reduced statistical power. By suggesting that self-compassion is reduced and possibly linked to life-satisfaction in BD, the findings highlight a potential vulnerability meriting further investigations.

2012-10-01

Compassion fatigue is a broad term comprising of two components - burnout and secondary traumatic stress. The current study is aimed at identifying 'burnout' and 'compassion fatigue' among clinicians involved in care of individuals suffering from medical illness. A total of 60 clinicians were included in the study. A semi-structured questionnaire was administered to gather information related to personal, professional, anthropometric, and metabolic profile of the study participants. Professional Quality of Life Scale (ProQoL Version V) was used to assess burnout, compassion satisfaction and secondary traumatic stress. Analysis was carried out using the SPSS version 19.0. The mean age of clinicians was 46.68±11.06 (range 26-67 years). Burnout score was significantly higher in those involved in diabetology practice. Similarly, compassion satisfaction score was greater among those with greater years of practice as well as among those in private practice. Clinicians who reported a poor working condition, as opposed to good, had more burnout and less compassion satisfaction. The current study suggests that it is important to find out ways of decreasing burnout and compassion fatigue among clinicians.

Because of the nature of the helping professions, nurses are at high risk for compassion fatigue and burnout. In the past, many researchers have studied compassion fatigue and burnout in nurses. However, reports of research assessing liver and kidney transplant nurse coordinators' compassion fatigue and burnout are rare. To assess liver and kidney transplant nurse coordinators' levels of compassion fatigue and burnout. A nonexperimental, exploratory descriptive study was conducted using the Professional Quality of Life Scale Version 5 (ProQOL-V), a 30-item self-report instrument to measure participants' level of compassion satisfaction, burnout, and secondary traumatic stress. This study sampled 14 liver and kidney transplant nurse coordinators from a large multiorgan transplant center in the Southeast region. Transplant nurse coordinators had an average level of compassion satisfaction, an average level of burnout, and an average level of secondary traumatic stress. Within liver and kidney transplant nurse coordinators, a statistically significant relationship was found between education levels of transplant nurse coordinators and the level of burnout, suggesting that education levels may influence burnout.

Why and how is compassion necessary to provide good quality healthcare?

Recent disclosures of failures of care in the National Health Service (NHS) in England have led to debates about compassion deficits disallowing health professionals to provide high quality responsive care. While the link between high quality care and compassion is often taken for granted, it is less obvious how compassion – often originating in the individual’s emotional response – can become a moral sentiment and lead to developing a system of norms and values underpinning ethics of care. In this editorial, I argue why and how compassion might become a foundation of ethics guiding health professionals and a basis for ethics of care in health service organisations. I conclude by discussing a recent case of prominent healthcare failure in the NHS to highlight the relationship between compassion as an aspect of professional ethics on the one hand, and values and norms that institutions and specific policies promote on the other hand.

Emergency rescue personnel can be considered a "high risk" occupational group in that they could experience a broad range of health and mental health consequences as a result of work-related exposures to critical incidents. This study examined the resilience factors that protect mental health among first responders. Nine hundred and sixty-one first responders filled out an on-line questionnaire, containing measure of sense of community, collective efficacy, self-efficacy and work-related mental health outcomes (compassion fatigue, burnout and compassion satisfaction). First responders reported high level of compassion satisfaction and low level of burnout and compassion fatigue. Compassion fatigue was predicted by self-efficacy, burnout was predicted by self-efficacy, collective efficacy and sense of community, compassion satisfaction was predicted by self-efficacy and sense of community. Resilience following critical events is common among first responders. Self-efficacy, collective efficacy and sense of community could be considered resilience factors that preserve first responders' work-related mental health.

Empathic connection with one's patients is essential to genetic counselor clinical practice. However, repeatedly engaging with distressed patients may cause compassion fatigue, a phenomenon characterized as feeling overwhelmed by experiencing patients' suffering. In order to extend findings of an initial qualitative study, we surveyed 222 genetic counselors about their compassion fatigue and factors that predict its occurrence. Multiple regression analysis identified seven significant predictors accounting for 53.7% of the variance in compassion fatigue. Respondents at higher risk of compassion fatigue were more likely to report being burned out, using self-criticism and giving up to manage stress, experiencing a greater variety of distressing clinical events, having larger patient caseloads, relying on religion as a coping strategy, having no children, and seeking support to manage stress. Respondents also provided critical incidents regarding their compassion fatigue and themes in these incidents are described. Practice and research recommendations are provided.

Indubitably, the challenges facing health-care social workers are becoming increasingly complex. Whilst these problematic professional circumstances compound the need for self-compassion among health-care social workers, few studies, if any, have explicitly examined self-compassion among this practitioner group. This cross-sectional study explored self-compassion among a sample of practitioners (N = 138) in one southeastern state. Results indicate that health-care social workers in this sample engage in self-compassion only moderately. Further, occupational and demographic/life characteristics (e.g., age, years practicing social work, average hours worked per week, health status, and relationship status, among others) are able to predict self-compassion scores. After a terse review of relevant literature, this paper will explicate findings from this study, discuss relevant points derived from said findings, and identify salient implication for health-care social work praxis.

This descriptive, cross-sectional survey was conducted in inpatient nursing units and outpatient clinics in a cancer center in the midwestern United States. The sample of 153 healthcare providers included RNs, medical assistants, and radiology technicians. The fourth revision of the 30-item Professional Quality of Life (ProQOL R-IV) scale was used for measuring compassion fatigue, compassion satisfaction, and burnout. A series of cross tab analyses examined the relationship between participant demographics and three ProQOL R-IV subscales. The study sample scored similarly on compassion satisfaction and burnout when compared with participants who used the ProQOL R-IV in previous studies. Value exists in analyzing the prevalence of burnout and compassion fatigue among oncology healthcare providers. Understanding the needs of distinct demographic groups offers valuable direction for intervention program development. Applying internal evidence in the design of a relevant stress-reduction program will better equip healthcare providers to recognize and manage compassion fatigue and burnout.

Background Compassion is a core value embedded in the concept of quality in healthcare. The need for compassion toward healthcare staff in the workplace, for their own health and well-being and also to enable staff to deliver compassionate care for patients, is increasingly understood. However, we do not currently know how healthcare staff understand and characterize compassion toward themselves as opposed to patients. Objective The aim of this study was to use social media for the generation and collection of primary data to gain understanding of the concept of workplace compassion. Methods Tweets that contained the hashtag #ShowsWorkplaceCompassion were collected from Twitter and analyzed. The study took place between April 21 and May 21, 2016. Participants were self-selecting users of the social media service Twitter. The study was promoted by a number of routes: the National Health Service (NHS) England website, the personal Twitter accounts of the research team, internal NHS England communications, and via social media sharing. Participants were asked to contribute their views about what activities, actions, policies, philosophies or approaches demonstrate workplace compassion in healthcare using the hashtag #ShowsWorkplaceCompassion. All tweets including the research hashtag #ShowsWorkplaceCompassion were extracted from Twitter and studied using content analysis. Data concerning the frequency, nature, origin, and location of Web-based engagement with the research campaign were collected using Bitly (Bitly, Inc, USA) and Symplur (Symplur LLC, USA) software. Results A total of 260 tweets were analyzed. Of the 251 statements within the tweets that were coded, 37.8% (95/251) of the statements concerned Leadership and Management aspects of workplace compassion, 29.5% (74/251) were grouped under the theme related to Values and Culture, 17.5% (44/251) of the statements related to Personalized Policies and Procedures that support workplace compassion, and 15.2% (38/251) of the statements concerned Activities and Actions that show workplace compassion. Content analysis showed that small acts of kindness, an embedded organizational culture of caring for one another, and recognition of the emotional and physical impact of healthcare work were the most frequently mentioned characteristics of workplace compassion in healthcare. Conclusions This study presents a new and innovative research approach using Twitter. Although previous research has analyzed the nature and pattern of tweets retrospectively, this study used Twitter to both recruit participants and collect primary data. PMID:29685866

Compassion as the reunion of feminine and masculine virtues in medicine

2017-01-01

The central role of the virtue of compassion in the shaping of the professional character of healthcare providers is a well-emphasized fact. On the other hand, the utmost obligation of physicians is to alleviate or eliminate human suffering. Traditionally, according to the Aristotelian understanding of virtues and virtue ethics, human virtues have been associated with masculinity. In recent decades, the founders of the ethics of care have introduced a set of virtues with feminine nature. This paper analyzes the notion of compassion as a common virtue between the traditional/masculine and care/feminine sets of virtues and shows that compassion is a reunion and merging point of both sets of human virtues. This role can be actualized through the development and promotion of compassion as an important part of the character of an ideal physician/healthcare provider. In addition, this paper argues that the notion of compassion can shed light on some important aspects of the contemporary debates on healthcare provider-patient relationship and medical futility. Despite the recent technological and scientific transformations in medicine, the interpersonal relationship between healthcare providers and patients still plays a vital role in pursuing the goals of healthcare. The virtue of compassion plays a central role in the establishment of a trust-based physician-patient relationship. This central role is discernible in the debate of medical futility in which making difficult decisions, depends largely on trust and rapport which are achievable by compassion in the physician and the recognition of this compassion by the patients and their surrogate decision makers.

The study of wisdom has recently become a subject of growing scientific interest, although the concept of wisdom is ancient. This article focuses on conceptualization of wisdom in the Bhagavad Gita, arguably the most influential of all ancient Hindu philosophical/religious texts. Our review, using mixed qualitative/quantitative methodology with the help of Textalyser and NVivo software, found the following components to be associated with the concept of wisdom in the Gita: Knowledge of life, Emotional Regulation, Control over Desires, Decisiveness, Love of God, Duty and Work, Self-Contentedness, Compassion/Sacrifice, Insight/Humility, and Yoga (Integration of Personality). A comparison of the conceptualization of wisdom in the Gita with that in modern scientific literature shows several similarities, such as rich knowledge about life, emotional regulation, insight, and a focus on common good (compassion). Apparent differences include an emphasis on control over desires and renunciation of materialistic pleasures. Importantly, the Gita suggests that at least certain components of wisdom can be taught and learned. We believe that the concepts of wisdom in the Gita are relevant to modern psychiatry in helping develop psychotherapeutic interventions that could be more individualistic and more holistic than those commonly practiced today, and they aim at improving personal well-being rather than just psychiatric symptoms.

2013-10-01

The astrophysical origin of about half of the elements heavier than iron have been attributed to the rapid neutron capture process. The modeling of such a process requires not only the correct astrophysical conditions but also reliable nuclear physics. The properties of neutron-rich nuclei in the region just below the N = 82 shell closure are of particular interest as they are responsible for the A = 130 peak in the solar abundance pattern. An experiment to investigate half-lives and β-delayed neutron emission branching ratios of very neutron-rich Pd and Ag isotopes was performed at the GSI projectile FRagment Separator (FRS). The FRS was used to separate products from in-flight fission of a 900 MeV/u 238U beam. Ions of interest were then implanted in the Silicon IMplantation detector and Beta Absorber (SIMBA) array. The high pixelation of the implantation detectors allowed for time-position correlation of the order of several seconds between implants and decays. Neutrons emitted during the decay were detected by the BEta deLayEd Neutron detector (BELEN) which surrounded the SIMBA array. Resulting analysis of half-lives and neutron emission branching ratios including a time-dependent background will be presented.

Self-Compassion, Stress, and Coping

People who are high in self-compassion treat themselves with kindness and concern when they experience negative events. The present article examines the construct of self-compassion from the standpoint of research on coping in an effort to understand the ways in which people who are high in self-compassion cope with stressful events. Self-compassionate people tend to rely heavily on positive cognitive restructuring but do not appear to differ from less self-compassionate people in the degree to which they cope through problem-solving and distraction. Existing evidence does not show clear differences in the degree to which people who are low vs. high in self-compassion seek support as a coping strategy, but more research is needed. PMID:20686629

PanDA for COMPASS at JINR

Petrosyan, A. Sh.

2016-09-01

PanDA (Production and Distributed Analysis System) is a workload management system, widely used for data processing at experiments on Large Hadron Collider and others. COMPASS is a high-energy physics experiment at the Super Proton Synchrotron. Data processing for COMPASS runs locally at CERN, on lxbatch, the data itself stored in CASTOR. In 2014 an idea to start running COMPASS production through PanDA arose. Such transformation in experiment's data processing will allow COMPASS community to use not only CERN resources, but also Grid resources worldwide. During the spring and summer of 2015 installation, validation and migration work is being performed at JINR. Details and results of this process are presented in this paper.

B(E2;0+1→2+1) values for the unstable, neutron-rich nuclei 132,134Te were determined through Coulomb excitation, in inverse kinematics, of accelerated beams of these nuclei. The systematics of measured B(E2) values from the ground state to the first excited state have been extended to the N=82 shell closure in the Te nuclei and have been compared with the predictions of different theories. The measurements were performed at the Holifield Radioactive Ion Beam Facility (HRIBF) using the GRAFIK detector. The success of this approach, which couples a 5.7% efficient through-well NaI(Tl) γ-ray detector with thin foil microchannel plate beam detectors, also demonstrates the feasibility for Coulomb excitation studies of neutron-rich nuclei even further from the valley of beta stability, both at present-generation ISOL facilities and at the proposed Rare Isotope Accelerator.

ECAL0 is a new electromagnetic calorimeter designed for studying generalized parton distributions at the COMPASS II experiment at CERN. It will be located next to the target and will cover larger photon angles (up to 30 degrees). It is a modular high-granularity Shashlyk device with total number of individual channels of approx. 1700 and readout based on wavelength shifting fibers and micropixel avalanche photodiodes. Characterization of the calorimeter includes tests of particular sub-components, tests of complete modules and module arrays, as well as a pilot run of a fully-functional, quarter-size prototype in the COMPASS experiment. The main goals of the tests on low-intensity electron beam at the ELSA accelerator in Bonn were: to provide energy calibration using electrons, to measure angular response of the calorimeter and to perform an energy scan to cross-check previously collected data. A dedicated measurement setup was prepared for the tests, including a 3x3 array of the ECAL0 modules, a scintillating-fibre hodoscope and a remotely-controlled motorized movable platform. The measurements were performed using three electron energies: 3.2 GeV, 1.6 GeV and 0.8 GeV. They include a calibration of the whole detector array with a straight beam and multiple angular scans.

A Drift Chamber to Measure Charged Particles at COMPASS-II

Heitz, Robert; Compass Collaboration

2013-10-01

A new drift chamber (DC05) will be constructed to replace two tracking detector stations based on straw tubes, ST02 and ST03 in the COMPASS spectrometer. DC05 uses the designs from DC04, a previous drift chamber designed at CEA-Saclay, France, but adds the addition of more wires for improved acceptance. In addition to more wires DC05 will also change its front end electronics using a new pre-amplifier-discriminator chip (CMAD). DC05 consists of 8 layers of anode planes and 21 layers of G-10 material frames carrying cathode planes and gas windows. The wires are orientated with two layers in the vertical x-direction, two layers in the horizontal y-direction, two layers offset +10 deg of the vertical x-direction, and two layers offset -10 deg of the vertical x-direction. The wires in parallel directions are offset half a pitch to resolve left-right ambiguities. The purpose for different wire orientations is to reconstruct the 3D space particle trajectory to fit a particle track. Each layer of wires is covered on the top and bottom by a cathode plane of carbon coated mylar. All these layers are sandwiched between two steel stiffening frames for support and noise reduction. A future drift chamber, DC06, is also being designed based off of DC05. Research funded by NSF-PHY-12-05-671 Medium Energy Nuclear Physics.

The influence of trait-negative affect and compassion satisfaction on compassion fatigue in Australian nurses.

For this study, we examined the nature of the unique relationships trait-negative affect and compassion satisfaction had with compassion fatigue and its components of secondary traumatic stress and burnout in 273 nurses from 1 metropolitan tertiary acute hospital in Western Australia. Participants completed the Professional Quality of Life Scale (Stamm, 2010), Depression Anxiety Stress Scale (Lovibond & Lovibond, 2004), and the State-Trait Anxiety Inventory (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983). Bivariate correlation and hierarchical regression analyses were performed to examine and investigate 4 hypotheses. The results demonstrate a clear differential pattern of relationships with secondary traumatic stress and burnout for both trait-negative affect and compassion satisfaction. Trait-negative affect was clearly the more important factor in terms of its contribution to overall compassion fatigue and secondary traumatic stress. In contrast, compassion satisfaction's unique protective relationship only related to burnout, and not secondary traumatic stress. The results are therefore consistent with the view that compassion satisfaction may be an important internal resource that protects against burnout, but is not directly influential in protecting against secondary traumatic stress for nurses working in an acute-care hospital environment. With the projected nursing workforce shortages in Australia, it is apparent that a further understanding is warranted of how such personal variables may work as protective and risk factors.

Practical compassions: repertoires of practice and compassion talk in acute mental healthcare.

PubMed

Brown, Brian; Crawford, Paul; Gilbert, Paul; Gilbert, Jean; Gale, Corinne

2014-03-01

This article reports an exploratory study of the concept of compassion in the work of 20 mental health practitioners in a UK Midlands facility. Using notions of practice derived from phenomenology and Bourdieusian sociology and notions of emotional labour we identify two contrasting interpretive repertoires in discussions of compassion. The first, the practical compassion repertoire, evokes the practical, physical and bodily aspects of compassion. It involves organising being with patients, playing games, anticipating disruption and taking them outside for cigarettes. Practitioners described being aware that these practical, bodily activities could lead to patients 'opening up', disclosing their interior concerns and enabling practical, compassionate mental health work to take place. In contrast, the second, organisational repertoire, concerns organisational constraints on compassionate practice. The shortage of staff, the record-keeping and internal processes of quality control were seen as time-greedy and apt to detract from contact with patients. The findings are discussed in relation to Bourdieu and Merleau-Ponty's phenomenological accounts of practice and habit and set in context in the growing interest in placing compassion centrally in healthcare. We also explore how the exercise of compassion in the way our participants describe it can afford the more effective exercise of medical power. © 2013 The Author.

Effects of self-compassion workbook training on trauma-related guilt in a sample of homeless veterans: a pilot study.

PubMed

Held, Philip; Owens, Gina P

2015-06-01

The present pilot study examined the effects of a 4-week-long self-administered self-compassion training on trauma-related guilt and compared it to a stress inoculation control group. A total of 47 homeless male veterans who were living in transitional housing facilities volunteered to participate in this study. Participants were randomly assigned to either a self-compassion (N = 13) or a stress inoculation (N = 14) group and were asked to complete pre-, mid-, and postintervention assessments measuring changes in self-compassion, trauma-related guilt, and posttraumatic stress disorder severity. Participants in both interventions reported increased levels of self-compassion and equal reductions in trauma-related guilt. No other significant changes were noted. The results from this pilot study provide preliminary evidence for the use of self-compassion and stress inoculation trainings as effective interventions for trauma-related guilt. The findings also suggest that self-administered trainings in the form of workbooks may be a viable, cost-effective form of intervention for disadvantaged populations, such as homeless veterans in transitional housing, who may lack resources or access to professionals or paraprofessionals. The effects of both self-compassion training and stress inoculation training on the study variables and directions for future research on self-compassion and trauma-related guilt are discussed. © 2015 Wiley Periodicals, Inc.

Rethinking Compassion Fatigue Through the Lens of Professional Identity: The Case of Child-Protection Workers.

PubMed

Geoffrion, Steve; Morselli, Carlo; Guay, Stéphane

2016-07-01

Compassion fatigue is currently the dominant model in work-related stress studies that explain the consequences of caring for others on child-protection workers. Based on a deterministic approach, this model excludes the role of cognition a priori and a posteriori in the understanding of the impact of caregiving or providing social support. By integrating the notion of professional identity, this article adds a subjective perspective to the compassion fatigue model allowing for the consideration of positive outcomes and takes into account the influence of stress caused by accountability. Mainly, it is argued that meanings derived from identity and given to situations may protect or accelerate the development of compassion fatigue or compassion satisfaction. To arrive at this proposition, the notions of compassion fatigue and identity theory are first reviewed. These concepts are then articulated around four work-related stressors specific to child-protection work. In light of this exercise, it is argued that professional identity serves as a subjective interpretative framework that guides the understanding of work-related situations. Therefore, compassion fatigue is not only a simple reaction to external stimuli. It is influenced by meanings given to the situation. Furthermore, professional identity modulates the impact of compassion fatigue on psychological well-being. Practice, policy, and research implications in light of these findings are also discussed. © The Author(s) 2015.

Buffering Impostor Feelings with Kindness: The Mediating Role of Self-compassion between Gender-Role Orientation and the Impostor Phenomenon

PubMed Central

Patzak, Alexandra; Kollmayer, Marlene; Schober, Barbara

2017-01-01

The impostor phenomenon (IP) refers to high-achievers who underestimate their abilities and thus fear being unmasked as impostors. IP sufferers attribute their success to factors other than their abilities, entailing negative emotions, unfavorable motivations, and reduced well-being. The IP was originally conceptualized as a predominantly female experience, and is thus seen as an important psychological barrier for female academic careers. Empirical findings of gender differences in the IP are equivocal, but sparse research on associations between gender-role orientation and the IP indicates that feminine students suffer more intensely from the IP than masculine students. Femininity and masculinity are also related to self-compassion, a rather young construct that enhances emotional resilience, well-being, and academic achievement. Self-compassion involves being kind to oneself when failing, perceiving one’s inadequacies as part of the human condition, and being mindful about negative aspects of oneself. It reduces fear of failure, denial of competences, and self-doubts which are central components of the IP. However, relations between self-compassion and the IP have not been investigated to date. In this study, we examine self-compassion as a potential resilience factor against the IP, taking gender and gender-role orientation into account. In a cross-sectional online survey, we investigated 459 (315 female) high-achieving first-year undergraduate students. Results include: Female, feminine, and undifferentiated students score higher on measures of the IP and lower on measures of self-compassion than male, masculine, or androgynous students. Higher levels of the IP are associated with lower levels of self-compassion across all students tested. Self-compassion further mediates the relationship between gender-role orientation and the IP. Interventions to enhance self-compassion might thus be an effective way to overcome impostor feelings. Female, feminine, and undifferentiated students might benefit most from facilitation of self-compassion in education. PMID:28798714

Although many research articles, health policies and health care strategies identify compassion as an underpinning value and key component of health care quality, identifying a unified definition of compassion is challenging. For Higher Education Institutions implementing 'values-based' recruitment processes, a clearer understanding of this core concept is vital. Exploratory, qualitative design. Academic staff, health care students, clinicians and service users (n = 45), participated in nine focus groups where they were asked to define compassion in the context of health care. Data were transcribed verbatim and analysed using thematic analysis. Four overarching themes were drawn from the data. The first theme centred on the participants' definitions of compassion, while the second identified compassionate behaviours. The third theme related to the barriers and threats to compassionate practice and the fourth, focused on ways to support compassion in practice. Participants believed that the health care staff should be 'consistently compassionate', and were emphatic that compassion should not be substituted with a 'care without engagement' approach. The findings concur with other research, which identifies the link between compassion and empathy and the importance of establishing meaningful connections with others. While participants in this study recognised the pressures of health care work and accepted that the expectation of 'consistent compassion' was not necessarily realistic, it was still seen as an important goal. Participants held clear expectations regarding practitioners' communication skills and used these as a proxy for compassionate practice. The 'Framework for Compassionate Inter-personal Relations' may be used to promote reflection on the implementation of compassionate practice. It may also be used to highlight areas of focus when conducting values-based recruitment activities. © 2015 John Wiley & Sons Ltd.

An empirical examination of the factor structure of compassion.

Compassion has long been regarded as a core part of our humanity by contemplative traditions, and in recent years, it has received growing research interest. Following a recent review of existing conceptualisations, compassion has been defined as consisting of the following five elements: 1) recognising suffering, 2) understanding the universality of suffering in human experience, 3) feeling moved by the person suffering and emotionally connecting with their distress, 4) tolerating uncomfortable feelings aroused (e.g., fear, distress) so that we remain open to and accepting of the person suffering, and 5) acting or being motivated to act to alleviate suffering. As a prerequisite to developing a high quality compassion measure and furthering research in this field, the current study empirically investigated the factor structure of the five-element definition using a combination of existing and newly generated self-report items. This study consisted of three stages: a systematic consultation with experts to review items from existing self-report measures of compassion and generate additional items (Stage 1), exploratory factor analysis of items gathered from Stage 1 to identify the underlying structure of compassion (Stage 2), and confirmatory factor analysis to validate the identified factor structure (Stage 3). Findings showed preliminary empirical support for a five-factor structure of compassion consistent with the five-element definition. However, findings indicated that the 'tolerating' factor may be problematic and not a core aspect of compassion. This possibility requires further empirical testing. Limitations with items from included measures lead us to recommend against using these items collectively to assess compassion. Instead, we call for the development of a new self-report measure of compassion, using the five-element definition to guide item generation. We recommend including newly generated 'tolerating' items in the initial item pool, to determine whether or not factor-level issues are resolved once item-level issues are addressed.

Impact of Providing Compassion on Job Performance and Mental Health: The Moderating Effect of Interpersonal Relationship Quality.

PubMed

Chu, Li-Chuan

2017-07-01

To examine the relationships of providing compassion at work with job performance and mental health, as well as to identify the role of interpersonal relationship quality in moderating these relationships. This study adopted a two-stage survey completed by 235 registered nurses employed by hospitals in Taiwan. All hypotheses were tested using hierarchical regression analyses. The results show that providing compassion is an effective predictor of job performance and mental health, whereas interpersonal relationship quality can moderate the relationships of providing compassion with job performance and mental health. When nurses are frequently willing to listen, understand, and help their suffering colleagues, the enhancement engendered by providing compassion can improve the provider's job performance and mental health. Creating high-quality relationships in the workplace can strengthen the positive benefits of providing compassion. Motivating employees to spontaneously exhibit compassion is crucial to an organization. Hospitals can establish value systems, belief systems, and cultural systems that support a compassionate response to suffering. In addition, nurses can internalize altruistic belief systems into their own personal value systems through a long process of socialization in the workplace. © 2017 Sigma Theta Tau International.

Many genetic counselors provide supervision to students during their career. Previous studies have shown genetic counselors, in general, are at increased risk for developing compassion fatigue. The purpose of this study was to determine if there was a difference in compassion fatigue and burnout levels in genetic counselors who currently supervise compared to genetic counselors who do not. Genetic counselors who currently practice in a clinical setting (N = 391) completed an online survey containing demographic questions, the Professional Quality of Life Scale, the State-Trait Anxiety Inventory, and questions specific to the genetic counselor's experiences with supervision. Overall, when controlling for trait-anxiety, the supervision role by itself was not independently associated with the risk for compassion fatigue and burnout among genetic counselors. Within supervisors, however, there were several factors which were associated with this risk. Those with less supervision experience reported more secondary traumatic stress. Those supervisors reporting less confidence had decreased compassion satisfaction. Those with less experience or less confidence in their supervision role were most likely to be at increased risk for developing compassion fatigue. Training in supervision and support for dealing with compassion fatigue and burnout may be beneficial to supervisors with less experience.

Compassion-based emotion regulation up-regulates experienced positive affect and associated neural networks

2015-01-01

Emotion regulation research has primarily focused on techniques that attenuate or modulate the impact of emotional stimuli. Recent evidence suggests that this mode regulation can be problematic in the context of regulation of emotion elicited by the suffering of others, resulting in reduced emotional connectedness. Here, we investigated the effects of an alternative emotion regulation technique based on the up-regulation of positive affect via Compassion-meditation on experiential and neural affective responses to depictions of individuals in distress, and compared these with the established emotion regulation strategy of Reappraisal. Using fMRI, we scanned 15 expert practitioners of Compassion-meditation either passively viewing, or using Compassion-meditation or Reappraisal to modulate their emotional reactions to film clips depicting people in distress. Both strategies effectively, but differentially regulated experienced affect, with Compassion primarily increasing positive and Reappraisal primarily decreasing negative affect. Imaging results showed that Compassion, relative to both passive-viewing and Reappraisal increased activation in regions involved in affiliation, positive affect and reward processing including ventral striatum and medial orbitfrontal cortex. This network was shown to be active prior to stimulus presentation, suggesting that the regulatory mechanism of Compassion is the stimulus-independent endogenous generation of positive affect.

Recent research has focused on the different types of compass cues available to ball-rolling beetles for orientation, but little is known about the relative precision of each of these cues and how they interact. In this study, we find that the absolute orientation error of the celestial compass of the day-active dung beetle Scarabaeus lamarcki doubles from 16° at solar elevations below 60° to an error of 29° at solar elevations above 75°. As ball-rolling dung beetles rely solely on celestial compass cues for their orientation, these insects experience a large decrease in orientation precision towards the middle of the day. We also find that in the compass system of dung beetles, the solar cues and the skylight cues are used together and share the control of orientation behaviour. Finally, we demonstrate that the relative influence of the azimuthal position of the sun for straight-line orientation decreases as the sun draws closer to the horizon. In conclusion, ball-rolling dung beetles possess a dynamic celestial compass system in which the orientation precision and the relative influence of the solar compass cues change over the course of the day.

With the rapid development of the COMPASS system, it is currently capable of providing regional navigation services. In order to test its data quality and performance for single point positioning (SPP), experiments have been conducted under different observing conditions including open sky, under trees, nearby a glass wall, nearby a large area of water, under high-voltage lines and under a signal transmitting tower. To assess the COMPASS data quality, the code multipath, cycle slip occurrence rate and data availability were analyzed and compared to GPS data. The datasets obtained from the experiments have also been utilized to perform combined GPS/COMPASS SPP on an epoch-by-epoch basis using unsmoothed single-frequency code observations. The investigation on the regional navigation performance aims at low-accuracy applications and all tests are made in Changsha, China, using the “SOUTH S82-C” GPS/COMPASS receivers. The results show that adding COMPASS observations can significantly improve the positioning accuracy of single-frequency GPS-only SPP in environments with limited satellite visibility. Since the COMPASS system is still in an initial operational stage, all results are obtained based on a fairly limited amount of data.

As adolescence can be a stressful developmental stage, the purpose of this study was to determine if a novel mindful self-compassion program would decrease stress, depressive symptoms, and anxiety and increase resilience, gratitude, and curiosity/exploration (positive risk-taking), and to ascertain if mindfulness and self-compassion co-varied with these outcomes over time. Forty-seven adolescents in the southeast U.S. enrolled in an 8-week mindful self-compassion course in five cohorts. Measures were assessed at pre-intervention, post-intervention, and 6-week follow-up. Multilevel growth analyses revealed main effects of time on perceived stress, resilience, curiosity/exploration and gratitude. Additionally, both mindfulness and self-compassion co-varied with perceived stress and depressive symptoms; mindfulness also co-varied with anxiety and self-compassion co-varied with resilience and curiosity/exploration. Implications of these findings are that this program has potential in decreasing stress and increasing resilience and positive risk-taking. Future studies with a control group need to be conducted to confirm these findings. Copyright © 2017 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

Body image satisfaction significantly influences self-esteem in female adolescents. Increased reports of lowered satisfaction in this population have raised concerns regarding their compromised self-esteem. This research study, therefore, sought to identify a culturally significant moderator of the association between body image satisfaction and self-esteem in Thai female adolescents. Orientation toward self-compassion, found to be particularly high in Thailand, was examined. A total of 302 Thai female undergraduates from three large public and private universities in the Bangkok metropolitan area responded to a set of questionnaires, which measured demographic information, body image satisfaction, self-compassion, and self-esteem. Data were analyzed using correlation and multiple regression analyses. Self-compassion was tested as a moderator of the relationship between body image satisfaction and self-esteem. Although its effect was relatively small, self-compassion significantly moderated the positive relationship between body image satisfaction and self-esteem. The relationship became less stringent for those with high self-compassion. The cultivation of self-compassion was recommended in female adolescents. In addition to moderating the association between body image satisfaction and self-esteem, the benefits to health and well-being of generalizing this cultivation are discussed.

Self-compassion may protect individuals experiencing poor body image and associated maladaptive outcomes. The purpose of the study was to examine within-person associations (whilst controlling for between-person differences) between appearance-related self-compassion, appearance-related threats (operationalised as upward appearance comparisons), and body image-related variables, namely, social physique anxiety, drive for thinness, and body dissatisfaction. A diary methodology was used whereby young women (n = 126; M age = 21.26) responded to brief online surveys three times per day (11am, 3pm, and 7pm) every second day for one week (i.e. a total of 12 measurement points). Results of mixed linear modeling revealed that both state appearance-related upward comparisons and self-compassion independently predicted all three outcomes in a positive and negative fashion, respectively. No significant interaction effects between state appearance-related upward comparisons and self-compassion were found. The results suggested that appearance-based self-compassion was important, not just when there was a potential threat to body image via upward appearance comparisons. The findings highlight the importance of fostering self-compassion on a daily level. © 2017 The International Association of Applied Psychology.

Background: Compassion fatigue is a broad term comprising of two components – burnout and secondary traumatic stress. The current study is aimed at identifying ‘burnout’ and ‘compassion fatigue’ among clinicians involved in care of individuals suffering from medical illness. Materials and Methods: A total of 60 clinicians were included in the study. A semi-structured questionnaire was administered to gather information related to personal, professional, anthropometric, and metabolic profile of the study participants. Professional Quality of Life Scale (ProQoL Version V) was used to assess burnout, compassion satisfaction and secondary traumatic stress. Analysis was carried out using the SPSS version 19.0. Results: The mean age of clinicians was 46.68±11.06 (range 26-67 years). Burnout score was significantly higher in those involved in diabetology practice. Similarly, compassion satisfaction score was greater among those with greater years of practice as well as among those in private practice. Clinicians who reported a poor working condition, as opposed to good, had more burnout and less compassion satisfaction. Conclusion: The current study suggests that it is important to find out ways of decreasing burnout and compassion fatigue among clinicians. PMID:23723540

Research suggests that the development of mindfulness and self-compassion may help to improve the well-being and resilience of professionals and students in the healthcare setting. This is reflected in the growth of mindfulness training for these individuals. Mindfulness is an important aspect of self-compassion, and healthcare professionals should be aware of the need to care for themselves when caring for others. This article explores the concepts of mindfulness and self-compassion and their relationship with, and ability to enhance, compassionate care.

To evaluate Compass, a new instrument for glaucoma screening and diagnosis that combines scanning ophthalmoscopy, automated perimetry, and eye tracking. A total of 320 human subjects (200 normal, 120 with glaucoma) underwent full ophthalmological evaluation and perimetric evaluation using the Humphrey SITA standard 24° test (HFA), and the Compass test that consisted of a full-threshold program on the central 24° with a photograph of the central 30° of the retina. A subgroup of normal subjects and glaucoma patients underwent a second Compass test during the same day in order to study test-retest variability. After exclusion of 30 patients due to protocol rules, a database was created to compare the Compass to the HFA, and to evaluate retinal image quality and fixation stability. The difference in mean sensitivity between Compass and HFA was -1.02 ± 1.55 dB in normal subjects (p<0.001) and -1.01 ± 2.81 dB in glaucoma (p<0.001). Repeatability SD for the average sensitivity was 1.53 for normal subjects and 1.84 for glaucoma. Test time with the Compass was 634±96 s (607±78 for normals, 678±108 for glaucoma). Compass analysis showed the percentage of fixation within the central 1° was 86.6% in normal subjects, and 79.3% in glaucoma patients. Color image quality was sufficient for diagnostic use in >65% of cases; Image-based diagnosis was in accordance with the initial diagnosis in 85% of the subjects. Based on preliminary results, Compass showed useful diagnostic characteristics for the study of glaucoma, and combined morphological information with functional data.

The Role of Compassion in Altruistic Helping and Punishment Behavior

Compassion, the emotional response of caring for another who is suffering and that results in motivation to relieve suffering, is thought to be an emotional antecedent to altruistic behavior. However, it remains unclear whether compassion enhances altruistic behavior in a uniform way or is specific to sub-types of behavior such as altruistic helping of a victim or altruistic punishment of a transgressor. We investigated the relationship between compassion and subtypes of altruistic behavior using third-party paradigms where participants 1) witnessed an unfair economic exchange between a transgressor and a victim, and 2) had the opportunity to either spend personal funds to either economically a) help the victim or b) punish the transgressor. In Study 1, we examined whether individual differences in self-reported empathic concern (the emotional component of compassion) was associated with greater altruistic helping or punishment behavior in two independent samples. For participants who witnessed an unfair transaction, trait empathic concern was associated with greater helping of a victim and had no relationship to punishment. However, in those who decided to punish the transgressor, participants who reported greater empathic concern decided to punish less. In Study 2, we directly enhanced compassion using short-term online compassion meditation training to examine whether altruistic helping and punishment were increased after two weeks of training. Compared to an active reappraisal training control group, the compassion training group gave more to help the victim and did not differ in punishment of the transgressor. Together, these two studies suggest that compassion is related to greater altruistic helping of victims and is not associated with or may mitigate altruistic punishment of transgressors.

The Providers Share Workshop (PSW) provides abortion providers safe space to discuss their work experiences. Our objectives were to assess changes in abortion stigma over time and explore how stigma is related to aspects of professional quality of life, including compassion satisfaction, burnout and compassion fatigue for providers participating in the workshops. Seventy-nine providers were recruited to the PSW study. Surveys were completed prior to, immediately following and 1 year after the workshops. The outcome measures were the Abortion Provider Stigma Survey and the Professional Quality of Life (ProQOL) survey. Baseline ProQOL scores were compared to published averages using t tests. Changes in abortion stigma and aspects of professional quality of life were assessed by fitting a two-level random-effects model with repeated measures at level 1 (period-level) and static measures (e.g., demographic data) at level 2 (person-level). Potential covariates included age, parenting status, education, organizational tenure, job type and clinic type (stand-alone vs. hospital-based clinics). Compared to other healthcare workers, abortion providers reported higher compassion satisfaction (t=2.65, p=.009) and lower burnout (t=5.13, p<.0001). Repeated-measures analysis revealed statistically significant decreases in stigma over time. Regression analysis identified abortion stigma as a significant predictor of lower compassion satisfaction, higher burnout and higher compassion fatigue. Participants in PSW reported a reduction in abortion stigma over time. Further, stigma is an important predictor of compassion satisfaction, burnout and compassion fatigue, suggesting that interventions aimed at supporting the abortion providing workforce should likely assess abortion stigma. Stigma is an important predictor of compassion satisfaction, burnout and compassion fatigue among abortion care providers. Therefore, strengthening human resources for abortion care requires stigma reduction efforts. Participants in the PSWs show reductions in stigma over time. Copyright © 2014 Elsevier Inc.

Background: Compassion is considered an essential element in quality patient care. One of the conceptual challenges in healthcare literature is that compassion is often confused with sympathy and empathy. Studies comparing and contrasting patients’ perspectives of sympathy, empathy, and compassion are largely absent. Aim: The aim of this study was to investigate advanced cancer patients’ understandings, experiences, and preferences of “sympathy,” “empathy,” and “compassion” in order to develop conceptual clarity for future research and to inform clinical practice. Design: Data were collected via semi-structured interviews and then independently analyzed by the research team using the three stages and principles of Straussian grounded theory. Setting/participants: Data were collected from 53 advanced cancer inpatients in a large urban hospital. Results: Constructs of sympathy, empathy, and compassion contain distinct themes and sub-themes. Sympathy was described as an unwanted, pity-based response to a distressing situation, characterized by a lack of understanding and self-preservation of the observer. Empathy was experienced as an affective response that acknowledges and attempts to understand individual’s suffering through emotional resonance. Compassion enhanced the key facets of empathy while adding distinct features of being motivated by love, the altruistic role of the responder, action, and small, supererogatory acts of kindness. Patients reported that unlike sympathy, empathy and compassion were beneficial, with compassion being the most preferred and impactful. Conclusion: Although sympathy, empathy, and compassion are used interchangeably and frequently conflated in healthcare literature, patients distinguish and experience them uniquely. Understanding patients’ perspectives is important and can guide practice, policy reform, and future research. PMID:27535319

The compass rose is one of the few "recurring patterns" found in financial markets. In this paper, the compass rose in Chinese A-share market is comprehensively investigated. It is newly discovered that among the 1331 A-shares, which had been listed for more than 15 years by the end of 2015, only about 20 show the compass rose. The outcome of the analysis shows that there exists a threshold of the ratio of the data points on main rays to all data points. Only when this ratio is above the threshold, the compass rose appears. The reasons why such a threshold exists, and its interrelationship with the data frequency and the tick/volatility ratio are analyzed.

Antennal circadian clocks coordinate sun compass orientation in migratory monarch butterflies.

During their fall migration, Eastern North American monarch butterflies (Danaus plexippus) use a time-compensated Sun compass to aid navigation to their overwintering grounds in central Mexico. It has been assumed that the circadian clock that provides time compensation resides in the brain, although this assumption has never been examined directly. Here, we show that the antennae are necessary for proper time-compensated Sun compass orientation in migratory monarch butterflies, that antennal clocks exist in monarchs, and that they likely provide the primary timing mechanism for Sun compass orientation. These unexpected findings pose a novel function for the antennae and open a new line of investigation into clock-compass connections that may extend widely to other insects that use this orientation mechanism.

[The psychology of compassion. An analysis of the 100th anniversary of the death of Fredrich Nietzsche].

PubMed

Wilkes, J

2000-06-01

Friedrich Nietzsche is supposed to have been one of the harshest critics of compassion. Many of his publications try to unmask its failings and to expose its true motives. From an ardent admirer of Schopenhauers's ethics of compassion, Nietzsche turned into a vigorous despiser of compassionate feelings. It is shown that this change was above all caused by overwhelming personal experiences of compassion due to illness and death in his family and, later on, with his first aid activities in military hospitals during the German-French war in 1870. Combined with that, Nietzsche suffered from feelings of passivity and helplessness, which gave him the impression of compassion being a negative and--in the end--loathed emotion.

Compassion is an attribute central to professionalism and modern clinical care, yet little is known about how compassion is acquired and preserved in medical training. We sought to understand whether personal illness experiences are thought by residents to foster compassion. The authors surveyed 155 (71% response rate) second- and third-year residents at the University of New Mexico School of Medicine regarding their views of the relationship of personal life experience with illness to compassion and empathy for patients. Residents believe that experience with personal health issues enhances physician compassion for patients. Residents who report more personal health concerns, such as physical or mental health problems and family health problems, endorse the connection between direct experience with illness and empathy. Health care trainees' own illness experiences may increase compassionate patient care practices and foster empathy. Copyright © 2011 The Academy of Psychosomatic Medicine. Published by Elsevier Inc.

2014-09-01

The current study examined whether self-compassion, the tendency to treat oneself kindly during distress and disappointments, would attenuate the positive relationship between body mass index (BMI) and eating disorder pathology, and the negative relationship between BMI and body image flexibility. One-hundred and fifty-three female undergraduate students completed measures of self-compassion, self-esteem, eating disorder pathology, and body image flexibility, which refers to one's acceptance of negative body image experiences. Controlling for self-esteem, hierarchical regressions revealed that self-compassion moderated the relationships between BMI and the criteria. Specifically, the positive relationship between BMI and eating disorder pathology and the negative relationship between BMI and body image flexibility were weaker the higher women's levels of self-compassion. Among young women, self-compassion may help to protect against the greater eating disturbances that coincide with a higher BMI, and may facilitate the positive body image experiences that tend to be lower the higher one's BMI.

Lying because we care: Compassion increases prosocial lying.

Lupoli, Matthew J; Jampol, Lily; Oveis, Christopher

2017-07-01

Prosocial lies, or lies intended to benefit others, are ubiquitous behaviors that have important social and economic consequences. Though emotions play a central role in many forms of prosocial behavior, no work has investigated how emotions influence behavior when one has the opportunity to tell a prosocial lie-a situation that presents a conflict between two prosocial ethics: lying to prevent harm to another, and honesty, which might also provide benefits to the target of the lie. Here, we examine whether the emotion of compassion influences prosocial lying, and find that compassion causally increases and positively predicts prosocial lying. In Studies 1 and 2, participants evaluated a poorly written essay and provided feedback to the essay writer. Experimentally induced compassion felt toward the essay writer (Study 1) and individual differences in trait compassion (Study 2) were positively associated with inflated feedback to the essay writer. In both of these studies, the relationship between compassion and prosocial lying was partially mediated by an enhanced importance placed on preventing emotional harm. In Study 3, we found moderation such that experimentally induced compassion increased lies that resulted in financial gains for a charity, but not lies that produced financial gains for the self. This research illuminates the emotional underpinnings of the common yet morally complex behavior of prosocial lying, and builds on work highlighting the potentially harmful effects of compassion-an emotion typically seen as socially beneficial.

Are improvements in shame and self-compassion early in eating disorders treatment associated with better patient outcomes?

PubMed

Kelly, Allison C; Carter, Jacqueline C; Borairi, Sahar

2014-01-01

Compassion-focused therapy (CFT; Gilbert, 2005, 2009) is a transdiagnostic treatment approach focused on building self-compassion and reducing shame. It is based on the theory that feelings of shame contribute to the maintenance of psychopathology, whereas self-compassion contributes to the alleviation of shame and psychopathology. We sought to test this theory in a transdiagnostic sample of eating disorder patients by examining whether larger improvements in shame and self-compassion early in treatment would facilitate faster eating disorder symptom remission over 12 weeks. Participants were 97 patients with an eating disorder admitted to specialized day hospital or inpatient treatment. They completed the Eating Disorder Examination-Questionnaire, Experiences of Shame Scale, and Self-Compassion Scale at intake, and again after weeks 3, 6, 9, and 12. Multilevel modeling revealed that patients who experienced greater decreases in their level of shame in the first 4 weeks of treatment had faster decreases in their eating disorder symptoms over 12 weeks of treatment. In addition, patients who had greater increases in their level of self-compassion early in treatment had faster decreases in their feelings of shame over 12 weeks, even when controlling for their early change in eating disorder symptoms. These results suggest that CFT theory may help to explain the maintenance of eating disorders. Clinically, findings suggest that intervening with shame early in treatment, perhaps by building patients' self-compassion, may promote better eating disorders treatment response.

This study explored the role of several psychological factors in professional quality of life in nurses. Specifically, we tried to clarify the relationships between several dimensions of empathy, self-compassion, and psychological inflexibility, and positive (compassion satisfaction) and negative (burnout and compassion fatigue) domains of professional quality of life. Using a cross-sectional design, a convenience sample of 221 oncology nurses recruited from several public hospitals filling out a battery of self-report measures. Results suggested that nurses that benefit more from their work of helping and assisting others (compassion satisfaction) seem to have more empathic feelings and sensibility towards others in distress and make an effort to see things from others' perspective. Also, they are less disturbed by negative feelings associated with seeing others' suffering and are more self-compassionate. Nurses more prone to experience the negative consequences associated with care-providing (burnout and compassion fatigue) are more self-judgmental and have more psychological inflexibility. In addition, they experience more personal feelings of distress when seeing others in suffering and less feelings of empathy and sensibility to others' suffering. Psychological factors explained 26% of compassion satisfaction, 29% of burnout and 18% of compassion fatigue. We discuss the results in terms of the importance of taking into account the role of these psychological factors in oncology nurses' professional quality of life, and of designing nursing education training and interventions aimed at targeting such factors.

Mission Critical: Nursing Leadership Support for Compassion to Sustain Staff Well-being.

PubMed

Lown, Beth A

Compassion, the foundation of Nursing, is a source of both healing for those who suffer and of purpose and meaning for those who seek to heal others. Increasingly, however, the fast pace and volume of care and documentation requirements diminish time with patients and families and hinder the enactment of compassion. These issues and other aspects of the work environment decrease the satisfaction and well-being of professional caregivers and are contributing to a rising tide of burnout. Research suggests that employee engagement emerges from their satisfaction and well-being; however, it is difficult for an individual to engage when she or he feels depleted and unsupported. Nursing leaders and managers can play a significant role in support of compassionate practices for staff and improvement of the work environment and staff well-being. Compassion practices that recognize employees for the caring they show to patients and each other, and that provide the support needed to sustain their caring and compassion, are associated with significantly better patient ratings of their care experiences in hospitals and ambulatory settings. This article describes an example of a compassion practice, Schwartz Rounds®, a program that has been implemented internationally to enhance staff caring and compassion, teamwork, and psychological well-being. Schwartz Rounds have been included as a component of organizational initiatives to enhance staff well-being and patient experience, and as an individual program. Nurse leaders and managers who wish to engage their staff can do so by supporting their compassion and well-being.

A comparative oxidation study of several amorphous Co 75- xFe 5(BSi) 20+ x alloys was carried out. Reentrant magnetization behavior and field-induced anisotropy which are of a critical importance for a magnetic detector were obtained after oxidation of the amorphous Co-rich ribbons. During this oxidation, the ribbons develop surface oxides which are primarily nonmagnetic borosilicate or a combination of borosilicate and magnetic oxides such CoO or FeO. Beneath this lies a 100-1000 Å thick Co-rich magnetic alloy which may be either HCP or FCC in its crystal structure. The thickness of the Co-crystallized layer is determined by the type of the surface oxides. The oxidation products such as appear to affect the reentrant magnetization behavior of Co-rich amorphous alloys significantly. We have determined the amount of metalloids (a critical concentration of B and Si) which is necessary to form a continuous layer of the most thermodynamically stable oxide, in our case borosilicate, on the surface. We also observed that there is a good correlation between reentrant magnetization and the thickness of Co layer. The best reentrant M- H loop for the magnetic detector was obtained in ribbons with a surface borate-rich borosilicate since it ensures conditions such as (1) metalloid depletion in the substrate and (2) formation of oxygen impurity faults in Co grains that are required for strong reentrant magnetization behavior.

2017-03-01

A micropattern and wire chamber hybrid has been constructed for UV photon detection, and its performance evaluated. It is revealed that such combination retains some key advantages of both the Thick-GEM primary and CCC secondary amplification stages, and results in a high gain gaseous photon detector with outstanding stability. Key features such as MIP suppression, detection efficiency and photon cluster size are discussed. The capability of the detector for UV photon detection has been established and proven with Cherenkov photons in particle beam tests.

The concept of compassion within uk media generated discourse: A corpus informed analysis.

To examine how the concept of compassion is socially constructed within UK discourse, in response to recommendations that aspiring nurses gain care experience prior to entering nurse education. Following a report of significant failings in care, the UK government proposed prior care experience for aspiring nurses as a strategy to enhance compassion amongst the profession. Media reporting of this generated substantial online discussion, which formed the data for this research. There is a need to define how compassion is constructed through language as a limited understanding exists, of what compassion means in healthcare. This is important, for any meaningful evaluation of quality, compassionate practices. A corpus-informed discourse analysis. A 62626-word corpus of data was analysed using Laurence Anthony software 'AntCon', a free corpus analysis toolkit. Frequent words were retrieved and used as a focal point for further analysis. Concordance lines were computed and analysed in the context of which frequent word-types occurred. Patterns of language were revealed and interpreted through researcher immersion. Findings identified that compassion was frequently described in various ways as a natural characteristic attribute. A pattern of language also referred to compassion as something that was not able to be taught, but could be developed through the repetition of behaviours observed in practice learning. In the context of compassion, the word-type 'nurse' was used positively. This paper adds to important debates highlighting how compassion is constructed and defined in the context of nursing. Compassion is constructed as both an individual, personal trait and a professional behaviour to be learnt. Educational design could include effective interpersonal skills training, which may help enhance and develop compassion from within the nursing profession. Likewise, ways of thinking, behaving and communicating should also be addressed by established practitioners in order to maintain compassionate interactions between professionals as well as nurse-patient relationships. Future research should focus on how compassionate practice is defined by both health professionals and patients. In order to maintain nursing as an attractive profession to join, it is important that nurses are viewed as compassionate. This holds implications for professional morale, associated with the continued retention and recruitment of the future workforce. Existing ideologies within the practice placement, the prior care experience environment, as well as the educational and organisational design are crucial factors to consider, in terms of their influences on the expression of compassion in practice.

Association among self-compassion, childhood invalidation, and borderline personality disorder symptomatology in a Singaporean sample.

Keng, Shian-Ling; Wong, Yun Yi

2017-01-01

Linehan's biosocial theory posits that parental invalidation during childhood plays a role in the development of borderline personality disorder symptoms later in life. However, little research has examined components of the biosocial model in an Asian context, and variables that may influence the relationship between childhood invalidation and borderline symptoms. Self-compassion is increasingly regarded as an adaptive way to regulate one's emotions and to relate to oneself, and may serve to moderate the association between invalidation and borderline symptoms. The present study investigated the association among childhood invalidation, self-compassion, and borderline personality disorder symptoms in a sample of Singaporean undergraduate students. Two hundred and ninety undergraduate students from a large Singaporean university were recruited and completed measures assessing childhood invalidation, self-compassion, and borderline personality disorder symptoms. Analyses using multiple regression indicated that both childhood invalidation and self-compassion significantly predicted borderline personality disorder symptomatology. Results from moderation analyses indicated that relationship between childhood invalidation and borderline personality disorder symptomatology did not vary as a function of self-compassion. This study provides evidence in support of aspects of the biosocial model in an Asian context, and demonstrates a strong association between self-compassion and borderline personality disorder symptoms, independent of one's history of parental invalidation during childhood.

A borehole survey instrument is provided having a meniscus type floating compass member with indicia thereon for indicating azimuth and inclination. A light source is disposed below the indicia for illuminating the indicia upward through the liquid through which the meniscus type floating compass member floats. A lens system is provided for focusing the image of the illuminated compass member upon a film disposed below the compass member. This arrangement permits the centering post for the compass member to be of minimum diameter consistent with rigidity requirements and permits a high angle compass member to indicate angles of inclination approachingmore » ninety degrees. A multiple light bulb light source is utilized and each light bulb is mounted in a manner which permits a single light bulb to illuminate the entire compass member. A hand-held programming and diagnostic unit is provided which may be momentarily electrically mated with the borehole survey tool to input a programmed timed delay and diagnostically test both the condition of the light bulbs utilized as the illumination source and the state of the batteries within the instrument. This hand-held programmable unit eliminates all the mechanical programming switches and permits the instrument to be completely sealed from the pressure, fluids and contaminants normally found in a well bore.« less

Self-Compassion as a Resource in the Self-Stigma Process of Overweight and Obese Individuals

2015-01-01

Objective Self-stigma in overweight and obese individuals has strong associations with impairment in mental and global health. This study sought to explore self-compassion as a psychological resource in the self-stigma process. Methods In a 2012 representative German population survey of N = 1,158 overweight and obese individuals, self-compassion was examined as a mediator between self-stigma and mental and physical health outcomes, including BMI (kg/m2), using structural equation modeling and controlling for sociodemographic factors. Results Psychological variables were assessed using validated self-report questionnaires. Self-compassion partially mediated the relationships between self-stigma and depression, somatic symptoms, and health status / quality of life, lowering the predictive effect of self-stigma on the outcomes by approximately one-third. In contrast, self-compassion, because it was unrelated to BMI, did not mediate the association between self-stigma and BMI. Conclusion Self-compassion has the potential to act as a buffer against the mental and global health detriments of self-stigma in overweight and obesity and could thus represent a target for interventions to reduce self-stigma and prevent these health impairments. In order to influence the association between self-stigma and BMI, self-compassion should conceptually be linked to weight management. PMID:26422226

Mind-body practices that intentionally generate positive emotion could improve health professionals' well-being and compassion. However, the feasibility and impact of clinician training in these practices is unknown. Data were analyzed from 3 online modules offered to health professionals: (a) Gratitude, (b) Positive Word, and (c) Loving-kindness/Compassion meditation. Pairedttests were used to assess pre- to posttraining changes in gratitude (Gratitude Questionnaire), well-being (World Health Organization Well-Being Index), self-compassion (Neff's Self-Compassion Scale), and confidence in providing compassionate care (Confidence in Providing Calm, Compassionate Care Scale). The 177 enrollees included diverse practitioners (nurses, physicians, social workers, and others). Training was associated with statistically significant improvements in gratitude (38.3 ± 4.6 to 39.5 ± 3.3), well-being (16.4 ± 4.0 to 17.9 ± 4.2), self-compassion (39.5 ± 8.1 to 43.1 ± 7.6), and confidence in providing compassionate care (73.3 ± 16.4 to 80.9 ± 13.8;P< .001 for all comparisons).

Self-compassion and emotional intelligence in nurses.

PubMed

Heffernan, Mary; Quinn Griffin, Mary T; Sister Rita McNulty; Fitzpatrick, Joyce J

2010-08-01

Nurses often provide care for patients and families who are suffering and where emotions are heightened. Compassion is an essential component of the care that nurses provide. Emotions play an important role in the relationship and communication between nurses, patients and families. Self-compassion is the ability to be compassionate to oneself, without this ability nurses might not be prepared to be compassionate to patients. Emotionally intelligent persons perceive themselves as confident, better able to understand, control and manage their emotions. The purpose of this descriptive, correlational study was to examine the relationship between self-compassion and emotional intelligence. Participants were 135 nurses. The setting for this study was a health system with hospitals located in Queens, Nassau and Suffolk counties of New York, USA. Three of the hospitals in the study are located in Queens and/or the Queens/Nassau border. Queens is the most culturally diverse community in the USA. The patients served, as well as the nursing staff, are reflective of this cultural and religious diversity. Results indicated a positive correlation between self-compassion and emotional intelligence (r = 0.55). Recommendations for future research include: exploration of self-compassion and emotional intelligence in nurses, and identification of the benefits of enhancing self-compassion and emotional intelligence in nurses.

This study examined neural activation during the experience of compassion, an emotion that orients people toward vulnerable others and prompts caregiving, and pride, a self-focused emotion that signals individual strength and heightened status. Functional magnetic resonance images (fMRI) were acquired as participants viewed 55 s continuous sequences of slides to induce either compassion or pride, presented in alternation with sequences of neutral slides. Emotion self-report data were collected after each slide condition within the fMRI scanner. Compassion induction was associated with activation in the midbrain periaqueductal gray (PAG), a region that is activated during pain and the perception of others' pain, and that has been implicated in parental nurturance behaviors. Pride induction engaged the posterior medial cortex, a region that has been associated with self-referent processing. Self-reports of compassion experience were correlated with increased activation in a region near the PAG, and in the right inferior frontal gyrus (IFG). Self-reports of pride experience, in contrast, were correlated with reduced activation in the IFG and the anterior insula. These results provide preliminary evidence towards understanding the neural correlates of important interpersonal dimensions of compassion and pride. Caring (compassion) and self-focus (pride) may represent core appraisals that differentiate the response profiles of many emotions.

A RICH counter using a gas radiator of C 4F 10 and a photosensitive MWPC with pad readout has been developed, tested in particle beam at CERN and used in the CAPRICE98 balloon-borne experiment. The MWPC was operated with a TMAE and ethane mixture at atmospheric pressure and used a cathode pad plane to give an unambiguous image of the Cherenkov light. The induced signals in the pad plane were read out using the AMPLEX chip and CRAMS. The good efficiency of the Cherenkov light collection, the efficient detection of the weak signal from single UV photons together with a low noise level in the electronics of the RICH detector, resulted in a large number of detected photoelectrons per event. For β≃1 charge one particles, an average of 12 photoelectrons per event were detected. The reconstructed Cherenkov angle of 50 mrad for a β≃1 particle had a resolution of 1.2 mrad (rms). The RICH was flown with the CAPRICE98 magnetic spectrometer and was the first RICH counter ever used in a balloon-borne experiment capable of identifying charge one particles at energies above 5 GeV. The RICH provided an identification of cosmic ray antiprotons up to the highest energies ever studied (about 50 GeV of total energy). The spectrometer was flown on 28-29 May 1998 from Fort Sumner, New Mexico, USA.

The desired moral attitude of the physician: (II) compassion.

PubMed

Gelhaus, Petra

2012-11-01

Professional medical ethics demands of health care professionals in addition to specific duties and rules of conduct that they embody a responsible and trustworthy personality. In the public discussion, different concepts are suggested to describe the desired implied attitude of physicians. In a sequel of three articles, a set of three of these concepts is presented in an interpretation that is meant to characterise the morally emotional part of this attitude: "empathy", "compassion" and "care". In the first article of the series, "empathy" has been developed as a mainly cognitive and morally neutral capacity of understanding. In this article, the emotional and virtuous core of the desired professional attitude-compassion-is elaborated. Compassion is distinguished from sympathy, empathy and pity. Several problems of compassion as a spontaneous, warm emotion for being a professional virtue are discussed: especially questions of over-demand, of justice and of concerns because of a possible threat to the patient's dignity and autonomy. An interpretation of compassion as processed and learned professional attitude, that founds dignity on the general idea of man as a sentient being and on solidarity, not on his independence and capacities, is developed. It is meant to rule out the possible side effects and to make compassion as a professional attitude and as professional virtue attractive, teachable and acquirable. In order to reach the adequate warmth and closeness for the particular physician-patient-relation, professional compassion has to be combined with the capacity of empathy. If appropriate, the combination of both empathy and compassion as "empathic compassion" can demand a much warmer attitude towards the patient than each of the elements alone, or the simple addition of them can provide. The concept of "care" that will be discussed in a forthcoming article of this sequel is a missing necessary part to describe the active potential of the desired moral attitude of the physician more completely. The reconstruction of the desired professional attitude in terms of "empathic compassionate care" is certainly not the only possible description, but it is a detailed proposal in order to give an impulse for the discussion about the inner tacit values and the meaning of medicine and clinical healthcare professions.

The most widely used measure of posttraumatic growth (PTG) is the Posttraumatic Growth Inventory (PTGI). Qualitative research indicates the importance of increased compassion as a result of struggling with challenges presented by cancer and treatments. However, current PTG measures may not adequately assess compassion. A cross-sectional survey of 514 prostate cancer survivors assessed the PTGI and Dispositional Positive Emotional Scale (DPES). Five additional PTG items were derived from previous qualitative research to assess increased compassion. After removing eight items with complex loadings, a principal components analysis with oblimin rotation revealed a six-component structure. A clear delineation was seen between components relating to compassion, new possibilities, relating to others, personal strength, appreciation of life and spiritual change. Compassion accounted for 48.9 % of variance in data, with the overall model accounting for 79.9 % of variance. Strong factorability was demonstrated through Kaiser-Meyer-Olkin (0.92) and Bartlett's test of sphericity (approximate χ (2) = 5,791.85, df 153, p < 0.001). The six-component structure was validated with a confirmatory factor analysis. Strong internal consistency was evidenced through Cronbach's alpha coefficients ranging from 0.74 to 0.90 for subscales, and item-to-total correlations and inter-item correlations exceeded accepted thresholds of 0.50 and 0.30, respectively. Convergent validity was acceptable between the PTGI compassion subscale and DPES (r = 0.50). Compassion is a highly salient PTG domain after prostate cancer. Further studies can explore this construct with more heterogeneous samples of cancer types and gender.

A novel method based on Pulse Coupled Neural Network(PCNN) algorithm for the highly accurate and robust compass information calculation from the polarized skylight imaging is proposed,which showed good accuracy and reliability especially under cloudy weather,surrounding shielding and moon light. The degree of polarization (DOP) combined with the angle of polarization (AOP), calculated from the full sky polarization image, were used for the compass information caculation. Due to the high sensitivity to the environments, DOP was used to judge the destruction of polarized information using the PCNN algorithm. Only areas with high accuracy of AOP were kept after the DOP PCNN filtering, thereby greatly increasing the compass accuracy and robustness. From the experimental results, it was shown that the compass accuracy was 0.1805° under clear weather. This method was also proven to be applicable under conditions of shielding by clouds, trees and buildings, with a compass accuracy better than 1°. With weak polarization information sources, such as moonlight, this method was shown experimentally to have an accuracy of 0.878°.

Self-compassionate responses to aging.

Allen, Ashley Batts; Leary, Mark R

2014-04-01

Evidence suggests that self-compassion may be beneficial to older adults who are struggling to cope with the aging process. The purpose of this study was to assess the thoughts of self-compassionate older adults and to determine whether self-compassionate thoughts relate to positive responses to aging. Participants (n = 121, M = 76.2 years, approximately 65% female) completed measures of self-compassion and self-esteem; were randomly assigned to write about a positive, negative, or neutral age-related event; and completed questions about the event and their reactions. Responses were coded for self-compassionate themes and emotional tone. Analyses indicated that self-compassion predicted positive responses to aging and that self-compassionate thoughts explained the relationship between trait self-compassion and emotional tone as well as the belief that one's attitude helped them cope with age-related events. Although older adults who were low versus high in self-compassion experienced similar age-related events, participants high in self-compassion thought about these events in ways that predicted positive outcomes. Encouraging older adults to be more self-compassionate may improve well-being in old age.

Remotely readable fiber optic compass

A remotely readable fiber optic compass. A sheet polarizer is affixed to a magnet rotatably mounted in a compass body, such that the polarizer rotates with the magnet. The optical axis of the sheet polarizer is preferably aligned with the north-south axis of the magnet. A single excitation light beam is divided into four identical beams, two of which are passed through the sheet polarizer and through two fixed polarizing sheets which have their optical axes at right angles to one another. The angle of the compass magnet with respect to a fixed axis of the compass body can be determined by measuring the ratio of the intensities of the two light beams. The remaining ambiguity as to which of the four possible quadrants the magnet is pointing to is resolved by the second pair of light beams, which are passed through the sheet polarizer at positions which are transected by two semicircular opaque strips formed on the sheet polarizer. The incoming excitation beam and the four return beams are communicated by means of optical fibers, giving a remotely readable compass which has no electrical parts.

DNA Compass: a secure, client-side site for navigating personal genetic information

2017-01-01

Abstract Motivation: Millions of individuals have access to raw genomic data using direct-to-consumer companies. The advent of large-scale sequencing projects, such as the Precision Medicine Initiative, will further increase the number of individuals with access to their own genomic information. However, querying genomic data requires a computer terminal and computational skill to analyze the data—an impediment for the general public. Results: DNA Compass is a website designed to empower the public by enabling simple navigation of personal genomic data. Users can query the status of their genomic variants for over 1658 markers or tens of millions of documented single nucleotide polymorphisms (SNPs). DNA Compass presents the relevant genotypes of the user side-by-side with explanatory scientific resources. The genotype data never leaves the user’s computer, a feature that provides improved security and performance. More than 12 000 unique users, mainly from the general genetic genealogy community, have already used DNA Compass, demonstrating its utility. Availability and Implementation: DNA Compass is freely available on https://compass.dna.land. Contact: yaniv@cs.columbia.edu PMID:28334237

Socialization in Context: Exploring Longitudinal Correlates of Mothers’ Value Messages of Compassion and Caution

Wray-Lake, Laura; Flanagan, Constance A.; Maggs, Jennifer L.

2012-01-01

This study examined correlates of mothers’ value messages using mother and adolescent reports across three years (N =1638 dyads). Two fundamental socialization dimensions were assessed: compassion messages (e.g., caring for others) and caution messages (e.g., being wary of others). Multilevel models revealed distinct between-person and within-person correlates for mothers’ compassion and caution messages. Individual differences in compassion messages were predicted by family context (e.g., mothers’ knowledge of friends and concerns for their child’s future) and neighborhood cohesion. Within-person effects demonstrated that compassion declined in concert with adolescents’ experiences of being bullied. Caution messages were predicted by mothers’ education levels, race/ethnicity, and marital status, and increased in relation to mothers’ concerns and perceptions that illegal substances were easily attainable in the community. Tests of age, period, and cohort effects unexpectedly revealed that longitudinal changes in compassion and caution were best explained by period effects. Consistent with new developments in value socialization theory, results suggest that mothers place emphasis on certain values based on their backgrounds, their children’s characteristics, and the broader social context.

This study investigated whether single-session self-compassion and self-esteem writing tasks ameliorate the body image concerns evoked by a negative body image induction. Ninety-six female university students aged 17-25 years (M age =19.45, SD=1.84) were randomly assigned to one of three writing treatment groups: self-compassion, self-esteem, or control. After reading a negative body image scenario, participants completed scales measuring state body appreciation, body satisfaction, and appearance anxiety. They then undertook the assigned writing task, and completed the three measures again, both immediately post-treatment and at 2-week follow-up. The self-compassion writing group showed higher post-treatment body appreciation than the self-esteem and control groups, and higher body appreciation than the control group at follow-up. At post-treatment and follow-up, self-compassion and self-esteem writing showed higher body satisfaction than the control. The groups did not differ on appearance anxiety. Writing-based interventions, especially those that enhance self-compassion, may help alleviate certain body image concerns. Copyright © 2017 Elsevier Ltd. All rights reserved.

Severn, Michael S; Searchfield, Grant D; Huggard, Peter

2012-01-01

This study aimed to investigate occupational stress amongst audiologists, along with quantification of their professional quality of life: Burnout, compassion fatigue, and compassion satisfaction. A cross-sectional postal survey research design using an audiology occupational stress questionnaire (AOSQ), and the professional quality of life (ProQOL) instrument. The sample consisted of members of the New Zealand Audiological Society. One hundred and forty-five questionnaires were mailed, 82 responses were received. The main findings suggest that six stress factors dominate clinical audiology: (1) time demand, (2) audiological management, (3) patient contact, (4) clinical protocol, (5) patient accountability, and (6) administration or equipment. A significant relationship was found between increasing age of the audiologist and risk of acquiring burnout (chi-square (1)=6.119, p<0.05). Pearson's correlation's revealed time demand was the strongest predictor of low compassion satisfaction (r=0.327) and burnout (r=0.463), while stress associated with patient contact was the strongest predictor of compassion fatigue (r=0.352). This study identifies sources of stress for clinical audiologists and different factors that contribute to professional quality of life.

Self-criticism is a ubiquitous feature of psychopathology and can be combatted by increasing levels of self-compassion. However, some patients are resistant to self-compassion. To investigate whether the effects of self-identification with virtual bodies within immersive virtual reality could be exploited to increase self-compassion in patients with depression. We developed an 8-minute scenario in which 15 patients practised delivering compassion in one virtual body and then experienced receiving it from themselves in another virtual body. In an open trial, three repetitions of this scenario led to significant reductions in depression severity and self-criticism, as well as to a significant increase in self-compassion, from baseline to 4-week follow-up. Four patients showed clinically significant improvement. The results indicate that interventions using immersive virtual reality may have considerable clinical potential and that further development of these methods preparatory to a controlled trial is now warranted.

Parenting an individual with intellectual and developmental disabilities (IDD) can be challenging, particularly during adulthood. It is important to better understand ways of supporting families as individuals with IDD age. Self-compassion is a potential internal coping resource for parents, and is strongly linked to positive mental health outcomes, though research has yet to examine it in parents of adults with IDD. The current study examines the association between self-compassion and measures of well-being for 56 parents of adults with IDD. Greater self-compassion was related to lower levels of stress and depression, even after accounting for other known stressors, such as economic disadvantage, having a child with an Autism Spectrum Disorder diagnosis, and high parent burden. Self-compassion may offer resiliency against these parenting challenges. © 2017 John Wiley & Sons Ltd.

Light-weight spherical mirrors have been appositely designed and built for the gas threshold Cherenkov detectors of the two Hall A spectrometers. The mirrors are made of a 1 mm thick aluminized plexiglass sheet, reinforced by a rigid backing consisting of a phenolic honeycomb sandwiched between two carbon fiber mats epoxy glued. The produced mirrors have a thickness equivalent to 0.55% of radiation length, and an optical slope error of about 5.5 mrad. These characteristics make these mirrors suitable for the implementation in Cherenkov threshold detectors. Ways to improve the mirror features are also discussed in view of their possible employment in RICH detectors.

Grief rumination mediates the association between self-compassion and psychopathology in relatives of missing persons.

PubMed

Lenferink, Lonneke I M; Eisma, Maarten C; de Keijser, Jos; Boelen, Paul A

2017-01-01

Background : The disappearance of a loved one is a unique type of loss, also termed 'ambiguous loss', which may heighten the risk for developing prolonged grief (PG), depression, and posttraumatic stress (PTS) symptoms. Little is known about protective and risk factors for psychopathology among relatives of missing persons. A potential protective factor is self-compassion, referring to openness toward and acceptance of one's own pain, failures, and inadequacies. One could reason that self-compassion is associated with lower levels of emotional distress following ambiguous loss, because it might serve as a buffer for getting entangled in ruminative thinking about the causes and consequences of the disappearance ('grief rumination'). Objective : In a sample of relatives of missing persons we aimed to examine (1) the prediction that greater self-compassion is related to lower symptom-levels of PG, depression, and PTS and (2) to what extent these associations are mediated by grief rumination. Method : Dutch and Belgian relatives of long-term missing persons ( N  = 137) completed self-report measures tapping self-compassion, grief rumination, PG, depression, and PTS. Mediation analyses were conducted. Results : Self-compassion was significantly, negatively, and moderately associated with PG, depression, and PTS levels. Grief rumination significantly mediated the associations of higher levels of self-compassion with lower levels of PG (a*b = -0.11), depression (a*b = -0.07), and PTS (a*b = -0.11). Specifically, 50%, 32%, and 32% of the effect of self-compassion on PG, depression, and PTS levels, respectively, was accounted for by grief rumination. Conclusions : Findings suggest that people with more self-compassion experience less severe psychopathology, in part because these people are less strongly inclined to engage in ruminative thinking related to the disappearance. Strengthening a self-compassionate attitude using, for instance, mindfulness-based interventions may therefore be a useful intervention to reduce emotional distress associated with the disappearance of a loved one.

In the Fall of 2017, Jefferson Lab's CLAS12 (CEBAF Large Acceptance Spectrometer) detector is expecting the addition of a RICH (ring imaging Cherenkov) detector which will allow enhanced particle identification in the momentum range of 3 to 8 GeV/c. RICH detectors measure the velocity of charged particles through the detection of produced Cherenkov radiation and the reconstruction of the angle of emission. The emitted Cherenkov photons are detected by a triangular-shaped grid of 391 multianode photomultiplier tubes (MAPMTs) made by Hamamatsu. The custom readout electronics consist of MAROC (multianode read out chip) boards controlled by FPGA (Field Programmable Gate Array) boards, and adapters used to connect the MAROC boards and MAPMTs. The focus of this project is the characterization of the MAPMTs with the new front end electronics. To perform these tests, a black box setup with a picosecond diode laser was constructed with low and high voltage supplies. A highly automated procedure was developed to acquire data at different combinations of high voltage values, light intensities and readout electronics settings. Future work involves using the collected data in calibration procedures and analyzing that data to resolve the best location for each MAPMT. SULI, NSF.

A large area ring-imaging Cherenkov detector has been designed to provide clean hadron identification capability in the momentum range from 3 GeV/c up to 8 GeV/c for the CLAS12 experiments at the upgraded 12 GeV continuous electron beam accelerator facility of Jefferson Laboratory. The adopted solution foresees a novel hybrid optics design based on aerogel radiator, composite mirrors and high-packed and high-segmented photon detectors. Cherenkov light will either be imaged directly (forward tracks) or after two mirror reflections (large angle tracks). We report here the results of the tests of a large scale prototype of the RICH detector performed withmore » the hadron beam of the CERN T9 experimental hall for the direct detection configuration. As a result, the tests demonstrated that the proposed design provides the required pion-to-kaon rejection factor of 1:500 in the whole momentum range.« less

The qualities of attachment with significant others and self-compassion protect adolescents from non suicidal self-injury.

Nonsuicidal self-injury (NSSI) is a serious public health problem. Identifying the factors that could help prevent or reduce NSSI is important. The current study examined the protective roles of the perceived qualities of current attachment to significant others (i.e., mothers, fathers, and peers) and self-compassion in adolescent NSSI. The potential mediating effect of self-compassion in the relationships between attachment relationships with mothers, fathers, and peers and adolescent NSSI was also explored. Self-reported data on mother, father, and peer attachment (each included 3 dimensions; i.e., trust, communication, and closeness); self-compassion; and NSSI were collected from 658 secondary school students (59.9% male; M age = 13.58 years). Participants with NSSI experiences scored significantly higher on the perceived qualities of current attachment with parents and self-compassion than those reporting no NSSI experience. Attachment with peers did not distinguish the NSSI group from the Non-NSSI group. Further mediation analyses indicated that self-compassion mediated the relationships of closeness with mothers, fathers (partially), and peers to NSSI as well as the relationship of peer communication to NSSI. Limitations of this study and implications regarding the protective roles of attachment and self-compassion in the prevention and intervention for NSSI are discussed.

Self-Compassion Scale (SCS): Psychometric Properties of The French Translation and Its Relations with Psychological Well-Being, Affect and Depression.

Kotsou, Ilios; Leys, Christophe

2016-01-01

Over the past few years, the topic of self-compassion has attracted increasing attention from both scientific and clinical fields. The Self-Compassion Scale (SCS) was created to specifically capture this way of being kind and understanding towards oneself in moments of turmoil. In this article, we present a French adaptation of the SCS. We first explore the psychometric properties of this adaptation and then investigate its relation to psychological well-being. As in the original version of the SCS, the French adaptation has a strong 6-factor structure but a weaker hierarchical second order structure. However the bi-factor model yields a good omega index suggesting the relevance of a single score accounting for self-compassion. Moreover, there was a relation between the SCS and classical outcomes such as a positive relation with psychological well-being and negative relation with depressive symptoms. We then hypothesized that self-compassion would have a moderating role on the relation between affect and depression. This hypothesis was confirmed: expressing negative affect is correlated with depressive symptoms; however, being kind with oneself lowers depressive symptoms even when expressing negative affect. In conclusion, this research presents a valid self-compassion measure for French-speaking researchers and clinicians and outlines the need for further research on the concept of self-compassion.

The aim of our study was to translate and to do a linguistic validation of the Composite Autonomic Symptom Score COMPASS 31. COMPASS 31 is a self-assessment instrument including 31 items assessing six domains of autonomic functions: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor functions. This questionnaire has been created by the Autonomic group of the Mayo Clinic from two previous versions: the Autonomic Symptom Profile (ASP) composed of 169 items and the following COMPASS with 72 items selected from the ASP. We translated the questionnaire by means of a standardized forward and back-translation procedure. Thirty-six subjects, 25 patients with autonomic failure of different aethiologies and 11 healthy controls filled in the COMPASS 31 twice, 4 ± 1 weeks apart, once in Italian and once in English in a randomized order. The test-retest showed a significant correlation between the Italian and the English versions as total score. The evaluation of single domains by means of Pearson correlation when applicable or by means of Spearman test showed a significant correlation between the English and the Italian COMPASS 31 version for all clinical domains except the vasomotor one for the lack of scoring. The comparison between the patients with autonomic failure and healthy control groups showed significantly higher total scores in patients with respect to controls confirming the high sensitivity of COMPASS 31 in revealing autonomic symptoms.

Mindfulness and Self-compassion as Unique and Common Predictors of Affect in the General Population.

López, Angélica; Sanderman, Robbert; Schroevers, Maya J

2016-01-01

In contrast to the increased research interest in the benefits of mindfulness and self-compassion, relatively few studies have examined their unique and combined effects in predicting affect. This cross-sectional study examined the predictive value of mindfulness and self-compassion for depressive symptoms, negative affect, and positive affect in a large representative sample of community adults ( N  = 1736). The Five Facets of Mindfulness Questionnaire (FFMQ) was used as a measure of mindfulness and the Self-Compassion Scale (SCS) as a measure of self-compassion. Five FFMQ facets were explored: observe, describe, act with awareness, non-judgment, and non-reactivity. Two SCS facets were explored: its positive items (SCS Pos) and its negative items (SCS Neg). When simultaneously examining all seven facets of mindfulness and self-compassion, three of the five FFMQ facets and SCS Neg significantly predicted both depressive symptoms and negative affect, with SCS Neg and act with awareness being the strongest predictors. These findings suggest that a harsh attitude towards oneself and a lack of attention when acting have the greatest value in predicting the presence of psychological symptoms. With respect to positive affect, four of the five FFMQ facets (except non-judgment) were significant predictors, with no unique predictive value of the two SCS's facets, suggesting that mindfulness is a more important predictor of positive affect than self-compassion, as measured by the FFMQ and SCS.

To interpret the body of qualitative work focusing on compassion fatigue to distil a common understanding that could then be applied to nursing care. Complex demands place extraordinary stress on nurses struggling to work in overburdened healthcare systems. The result can be the inability to care well for others, leading to compassion fatigue, burnout and increased numbers leaving the profession. Metasynthesis offers a means of more fully illuminating compassion fatigue and further understanding of practices which might reduce its negative consequences. Metasynthesis. As a method designed to facilitate knowledge development, metasynthesis allowed for integration of qualitative study findings conducted between 1992-2016 using defined search terms. Six databases were searched for articles published in English. Nine papers met the criteria for review and metasynthesis was conducted using the meta-ethnographic approach detailed by Noblit and Hare. Four themes related to compassion fatigue were found by consensus discussion. The themes included: physical ("just plain worn out") and emotional symptoms ("walking on a tightrope"), triggering factors ("an unbearable weight on shoulders" and "alone in a crowded room"), and measures to overcome/prevent ("who has my back?"). Compassion fatigue is a concept of documented relevance to those in nursing and represents a basic inability to nurture others and engenders a temporal component. Synthesis of studies provides evidence of the veracity of the concept for application to clinical practice and research related to nursing care. Findings provide insight into the clinical milieu needed to prevent compassion fatigue. A theoretical model is presented which can be used to guide future research, as well as the creation of clinical practice policies which might mitigate the development of compassion fatigue and its potential consequences. © 2017 The Authors.

Research suggests that being self-compassionate can have myriad benefits, including life satisfaction, health-promoting behaviours and improved mental health. Given the possible advantages of being self-compassionate, it seems critical to explore how to promote this in the general population. This qualitative study aimed to understand responses to the idea of being compassionate to oneself within the general population. Semi-structured interviews were conducted in the North East of England between October 2014 and February 2015, they were analysed using thematic analysis. As part of an intervention study, non-clinical volunteers watched a psychoeducation video about the concept of self-compassion and then participated in one of four meditation exercises. Following this, participants were interviewed about their responses to the idea of being self-compassionate. Three themes were identified: Benefits of Self-Compassion; Being Self-Compassionate and Barriers to Self-Compassion. Participants believed that being self-compassionate would be beneficial, for both themselves and the world, but they believed that self-compassion would make them vulnerable and that others would judge them. Thus, participants were afraid to be the first ones to be self-compassionate and stated that, in order for self-compassion to be acceptable, we need to change the perspective of western culture. These findings underscore the importance of understanding society's role in a person's ability to be self-compassionate. In order to reap the benefits of self-compassion, we need to create a culture that accepts and encourages this. As practitioners, we are in a position to lead in self-compassion and to encourage other leaders to promote this as a preventative mental health strategy. © 2016 John Wiley & Sons Ltd.

Zebra finches have a light-dependent magnetic compass similar to migratory birds.

Birds have a light-dependent magnetic compass that provides information about the spatial alignment of the geomagnetic field. It is proposed to be located in the avian retina and mediated by a light-induced, radical-pair mechanism involving cryptochromes as sensory receptor molecules. To investigate how the behavioural responses of birds under different light spectra match with cryptochromes as the primary magnetoreceptor, we examined the spectral properties of the magnetic compass in zebra finches. We trained birds to relocate a food reward in a spatial orientation task using magnetic compass cues. The birds were well oriented along the trained magnetic compass axis when trained and tested under low-irradiance 521 nm green light. In the presence of a 1.4 MHz radio-frequency electromagnetic (RF)-field, the birds were disoriented, which supports the involvement of radical-pair reactions in the primary magnetoreception process. Birds trained and tested under 638 nm red light showed a weak tendency to orient ∼45 deg clockwise of the trained magnetic direction. Under low-irradiance 460 nm blue light, they tended to orient along the trained magnetic compass axis, but were disoriented under higher irradiance light. Zebra finches trained and tested under high-irradiance 430 nm indigo light were well oriented along the trained magnetic compass axis, but disoriented in the presence of a RF-field. We conclude that magnetic compass responses of zebra finches are similar to those observed in nocturnally migrating birds and agree with cryptochromes as the primary magnetoreceptor, suggesting that light-dependent, radical-pair-mediated magnetoreception is a common property for all birds, including non-migratory species. © 2017.

Compassion Is a Necessity and an Individual and Collective Responsibility Comment on "Why and How Is Compassion Necessary to Provide Good Quality Healthcare?".

PubMed

Lown, Beth A

2015-06-02

Compassion is a complex process that is innate, determined in part by individual traits, and modulated by a myriad of conscious and unconscious factors, immediate context, social structures and expectations, and organizational "culture." Compassion is an ethical foundation of healthcare and a widely shared value; it is not an optional luxury in the healing process. While the interrelations between individual motivation and social structure are complex, we can choose to act individually and collectively to remove barriers to the innate compassion that most healthcare professionals bring to their work. Doing so will reduce professional burnout, improve the well-being of the healthcare workforce, and facilitate our efforts to achieve the triple aim of improving patients' experiences of care and health while lowering costs. © 2015 by Kerman University of Medical Sciences.

Migration along orthodromic sun compass routes by arctic birds.

Alerstam, T; Gudmundsson, G A; Green, M; Hedenstrom, A

2001-01-12

Flight directions of birds migrating at high geographic and magnetic latitudes can be used to test bird orientation by celestial or geomagnetic compass systems under polar conditions. Migration patterns of arctic shorebirds, revealed by tracking radar studies during an icebreaker expedition along the Northwest Passage in 1999, support predicted sun compass trajectories but cannot be reconciled with orientation along either geographic or magnetic loxodromes (rhumb lines). Sun compass routes are similar to orthodromes (great circle routes) at high latitudes, showing changing geographic courses as the birds traverse longitudes and their internal clock gets out of phase with local time. These routes bring the shorebirds from high arctic Canada to the east coast of North America, from which they make transoceanic flights to South America. The observations are also consistent with a migration link between Siberia and the Beaufort Sea region by way of sun compass routes across the Arctic Ocean.

On the use of magnets to disrupt the physiological compass of birds.

PubMed

Wang, K; Mattern, E; Ritz, T

2006-10-04

Behavioral researchers have attached magnets to birds during orientation experiments, assuming that such magnets will disrupt their ability to obtain magnetic information. Here, we investigate the effect of an attached magnet on the ability to derive directional information from a radical-pair based compass mechanism. We outline in some detail the geometrical symmetries that would allow a bird to identify magnetic directions in a radical-pair based compass. We show that the artificial field through an attached magnet will quickly disrupt the birds' ability to distinguish pole-ward from equator-ward headings, but that much stronger fields are necessary to disrupt their ability to detect the magnetic axis. Together with estimates of the functional limits of a radical-pair based compass, our calculations suggest that artificial fields of comparable size to the geomagnetic field are not generally sufficient to render a radical-pair based compass non-functional.

Anatomical Reconstruction and Functional Imaging Reveal an Ordered Array of Skylight Polarization Detectors in Drosophila

Bleul, Christiane; Baumann-Klausener, Franziska; Labhart, Thomas; Dickinson, Michael H.

Many insects exploit skylight polarization as a compass cue for orientation and navigation. In the fruit fly, Drosophila melanogaster, photoreceptors R7 and R8 in the dorsal rim area (DRA) of the compound eye are specialized to detect the electric vector (e-vector) of linearly polarized light. These photoreceptors are arranged in stacked pairs with identical fields of view and spectral sensitivities, but mutually orthogonal microvillar orientations. As in larger flies, we found that the microvillar orientation of the distal photoreceptor R7 changes in a fan-like fashion along the DRA. This anatomical arrangement suggests that the DRA constitutes a detector for skylight polarization, in which different e-vectors maximally excite different positions in the array. To test our hypothesis, we measured responses to polarized light of varying e-vector angles in the terminals of R7/8 cells using genetically encoded calcium indicators. Our data confirm a progression of preferred e-vector angles from anterior to posterior in the DRA, and a strict orthogonality between the e-vector preferences of paired R7/8 cells. We observed decreased activity in photoreceptors in response to flashes of light polarized orthogonally to their preferred e-vector angle, suggesting reciprocal inhibition between photoreceptors in the same medullar column, which may serve to increase polarization contrast. Together, our results indicate that the polarization-vision system relies on a spatial map of preferred e-vector angles at the earliest stage of sensory processing. SIGNIFICANCE STATEMENT The fly's visual system is an influential model system for studying neural computation, and much is known about its anatomy, physiology, and development. The circuits underlying motion processing have received the most attention, but researchers are increasingly investigating other functions, such as color perception and object recognition. In this work, we investigate the early neural processing of a somewhat exotic sense, called polarization vision. Because skylight is polarized in an orientation that is rigidly determined by the position of the sun, this cue provides compass information. Behavioral experiments have shown that many species use the polarization pattern in the sky to direct locomotion. Here we describe the input stage of the fly's polarization-vision system.

Beta-delayed neutron emission (βn) is the dominant decay channel for the majority of very neutron-rich nuclei. In order to study these decays a new detector system called the Versatile Array of Neutron Detectors at Low Energy (VANDLE) was constructed. A critical part of this neutron time of flight detector is a trigger unit. This trigger is sensitive to electron from beta decay down to very low energies, insensitive to gamma rays and have a good timing performance, better than 1 ns. In order to satisfy these condition, we have developed a new system, which utilizes plastic scintillator but uses recently developed light readout technique, based on the so called Silicon Photomultiplier, manufactured by Sensl. New system has been developed and performance tested using digital data acquisition system at the University of Tennessee and will be utilized in future experiments involving VANDLE.

2009-03-11

Conjugated linoleic acid (CLA)-rich soy oil has been produced by soy oil linoleic acid (LA) photoisomerization, but CLA-rich oil triacylglycerol (TAG) characterization was not described. Therefore, the objectives were to identify and quantify new TAG fractions in CLA-rich oil by nonaqueous reversed-phase high-performance liquid chromatography (NARP-HPLC). Analytical NARP-HPLC with an acetonitrile/dichloromethane (ACN/DCM) gradient and an evaporating light scattering detector/ultraviolet (ELSD/UV) detector was used. New TAG peaks from LA-containing TAGs were observed. The LnLL, LLL, LLO, and LLP (Ln, linolenic; L, linoleic; O, oleic; and P, palmitic) peaks reduced after isomerization with an increase in adjacent peaks that coeluted with LnLnO, LnLO, LnOO, and LnPP. The newly formed peaks were wider than those of the original oil and absorbed at 233 nm, suggesting the possibility of various CLA containing TAGs. The HPLC profile showed five fractions of mixed TAGs, and fatty acid analysis showed that CLA isomers were found predominately in fractions 2 and 3, which originally contained most LA. The CLA isomers were 70-80% trans,trans and 20-30% cis,trans and trans,cis.

Self-compassion and physical health: Exploring the roles of perceived stress and health-promoting behaviors

PubMed Central

Homan, Kristin J; Sirois, Fuschia M

2017-01-01

Growing evidence indicates that self-compassion is associated with better physical health, but the pathways that mediate this relationship are not well understood. This study tested a serial mediation model that linked self-compassion, perceived stress, health behaviors, and a comprehensive index of physical health. A sample of 176 individuals completed an online survey posted on Amazon’s Mechanical Turk. Self-compassion had an indirect effect on physical health via both mediators and through the sequential pathway, suggesting that taking a kind, accepting and mindful stance toward one’s flaws and failures may have benefits for reducing stress and promoting health behaviors.

This study examines the relationship between attachment classification, resiliency, and compassion fatigue in New York social workers following 9/11. We used single occasion, quasi-random sampling, surveying 481 social workers living in Manhattan. Hierarchical regression analyses revealed that secure attachment is predictive of the ability to cope with secondary traumatic stress as well as capacity for resilience, explaining approximately 7% of the variance in both compassion fatigue and resiliency. These findings suggest that secure attachment may serve as a source of resilience for social workers, immunizing them from significant compassion fatigue. Such findings have significant implications for clinicians working with traumatized populations.

Night-Migratory Songbirds Possess a Magnetic Compass in Both Eyes

Previous studies on European robins, Erithacus rubecula, and Australian silvereyes, Zosterops lateralis, had suggested that magnetic compass information is being processed only in the right eye and left brain hemisphere of migratory birds. However, recently it was demonstrated that both garden warblers, Sylvia borin, and European robins have a magnetic compass in both eyes. These results raise the question if the strong lateralization effect observed in earlier experiments might have arisen from artifacts or from differences in experimental conditions rather than reflecting a true all-or-none lateralization of the magnetic compass in European robins. Here we show that (1) European robins having only their left eye open can orient in their seasonally appropriate direction both during autumn and spring, i.e. there are no strong lateralization differences between the outward journey and the way home, that (2) their directional choices are based on the standard inclination compass as they are turned 180° when the inclination is reversed, and that (3) the capability to use the magnetic compass does not depend on monocular learning or intraocular transfer as it is already present in the first tests of the birds with only one eye open.

Self-compassion and reactions to unpleasant self-relevant events: the implications of treating oneself kindly.

Five studies investigated the cognitive and emotional processes by which self-compassionate people deal with unpleasant life events. In the various studies, participants reported on negative events in their daily lives, responded to hypothetical scenarios, reacted to interpersonal feedback, rated their or others' videotaped performances in an awkward situation, and reflected on negative personal experiences. Results from Study 1 showed that self-compassion predicted emotional and cognitive reactions to negative events in everyday life, and Study 2 found that self-compassion buffered people against negative self-feelings when imagining distressing social events. In Study 3, self-compassion moderated negative emotions after receiving ambivalent feedback, particularly for participants who were low in self-esteem. Study 4 found that low-self-compassionate people undervalued their videotaped performances relative to observers. Study 5 experimentally induced a self-compassionate perspective and found that self-compassion leads people to acknowledge their role in negative events without feeling overwhelmed with negative emotions. In general, these studies suggest that self-compassion attenuates people's reactions to negative events in ways that are distinct from and, in some cases, more beneficial than self-esteem.

Integration of polarization and chromatic cues in the insect sky compass.

el Jundi, Basil; Pfeiffer, Keram; Heinze, Stanley; Homberg, Uwe

2014-06-01

Animals relying on a celestial compass for spatial orientation may use the position of the sun, the chromatic or intensity gradient of the sky, the polarization pattern of the sky, or a combination of these cues as compass signals. Behavioral experiments in bees and ants, indeed, showed that direct sunlight and sky polarization play a role in sky compass orientation, but the relative importance of these cues are species-specific. Intracellular recordings from polarization-sensitive interneurons in the desert locust and monarch butterfly suggest that inputs from different eye regions, including polarized-light input through the dorsal rim area of the eye and chromatic/intensity gradient input from the main eye, are combined at the level of the medulla to create a robust compass signal. Conflicting input from the polarization and chromatic/intensity channel, resulting from eccentric receptive fields, is eliminated at the level of the anterior optic tubercle and central complex through internal compensation for changing solar elevations, which requires input from a circadian clock. Across several species, the central complex likely serves as an internal sky compass, combining E-vector information with other celestial cues. Descending neurons, likewise, respond both to zenithal polarization and to unpolarized cues in an azimuth-dependent way.

Few researchers have the data required to adequately understand how the school environment impacts youth health behaviour development over time. COMPASS is a prospective cohort study designed to annually collect hierarchical longitudinal data from a sample of 90 secondary schools and the 50,000+ grade 9 to 12 students attending those schools. COMPASS uses a rigorous quasi-experimental design to evaluate how changes in school programs, policies, and/or built environment (BE) characteristics are related to changes in multiple youth health behaviours and outcomes over time. These data will allow for the quasi-experimental evaluation of natural experiments that will occur within schools over the course of COMPASS, providing a means for generating "practice based evidence" in school-based prevention programming. COMPASS is the first study with the infrastructure to robustly evaluate the impact that changes in multiple school-level programs, policies, and BE characteristics within or surrounding a school might have on multiple youth health behaviours or outcomes over time. COMPASS will provide valuable new insight for planning, tailoring and targeting of school-based prevention initiatives where they are most likely to have impact.

Background Self-criticism is a ubiquitous feature of psychopathology and can be combatted by increasing levels of self-compassion. However, some patients are resistant to self-compassion. Aims To investigate whether the effects of self-identification with virtual bodies within immersive virtual reality could be exploited to increase self-compassion in patients with depression. Method We developed an 8-minute scenario in which 15 patients practised delivering compassion in one virtual body and then experienced receiving it from themselves in another virtual body. Results In an open trial, three repetitions of this scenario led to significant reductions in depression severity and self-criticism, as well as to a significant increase in self-compassion, from baseline to 4-week follow-up. Four patients showed clinically significant improvement. Conclusions The results indicate that interventions using immersive virtual reality may have considerable clinical potential and that further development of these methods preparatory to a controlled trial is now warranted.

The capacity to work productively is a key component of health and emotional well-being. People who work in health care can be exposed to the fatigue of care. Compassion fatigue has been described as an occupational hazard specific to clinical work related severe emotional distress. In our study, we have evaluated compassion fatigue in a mental health group (47 psychiatric staff) and its relationship with inpatients (237 inpatients) affected by some psychiatric disorders. At baseline, the more significant data indicate a high percentage of Job Burnout and Compassion Fatigue in psychiatric nurses (respectively, 39.28%, 28.57%). Significant Compassion Fatigue percentage is present also in psychologist group (36.36%). Finally, in psychiatrists, the exposure to patients increased vicarious trauma (28.57%), but not job burnout. After a year of participation in Balint Groups, the psychiatric staff presented an overall reduction in total mean score in any administered scale (CBI: p<0.0000045; sCFs: (Vicarious Trauma: p<0.0288; Job Burnout: p<0.000001)). Thus, compassion fatigue causes concern among mental health professionals, and Balint Groups may represent a therapeutic strategy to help health professionals to face difficulties in challenging work environments.

To explore compassion fatigue and compassion satisfaction with the potential contributing factors of anxiety, depression and stress. To date, no studies have connected the quality of work-life with other contributing and co-existing factors such as depression, anxiety and stress. A self-report exploratory cross sectional survey of 132 nurses working in a tertiary hospital. The reflective assessment risk profile model provides an excellent framework for examining the relationships between the professional quality of work factors and contributing factors within the established risk profiles. The results show a definite pattern of risk progression for the six factors examined for each risk profile. Additionally, burnout and secondary traumatic stress were significantly related to higher anxiety and depression levels. Higher anxiety levels were correlated with nurses who were younger, worked full-time and without a postgraduate qualification. Twenty percent had elevated levels of compassion fatigue: 7.6% having a very distressed profile. At-risk nurses' stress and depression scores were significantly higher than nurses with higher compassion satisfaction scores. The employed nurse workforce would benefit from a psychosocial capacity building intervention that reduces a nurse's risk profile, thus enhancing retention. © 2013 John Wiley & Sons Ltd.

Self-compassion, typically operationalized as the total score of the Self-Compassion Scale (SCS; Neff, 2003b), has been shown to be related to increased psychological well-being and lower depression in students of the social sciences, users of psychology websites and psychotherapy patients. The current study builds on the existing literature by examining the link between self-compassion and depressive symptomatology in a sample representative of the German general population (n = 2,404). The SCS subscales of self-judgment, isolation, and over-identification, and the “self-coldness”, composite score, which encompass these three negative subscales, consistently differed between subsamples of individuals without any depressive symptoms, with any depressive syndromes, and with major depressive disorder. The contribution of the positive SCS subscales of self-kindness, common humanity, and mindfulness to the variance in depressive symptomatology was almost negligible. However, when combined to a “self-compassion composite”, the positive SCS subscales significantly moderated the relationship between “self-coldness” and depressive symptoms in the general population. This speaks for self-compassion having the potential to buffer self-coldness related to depression—providing an argument for interventions that foster self-caring, kind, and forgiving attitudes towards oneself.

Tenebrio beetles use magnetic inclination compass

Animals that guide directions of their locomotion or their migration routes by the lines of the geomagnetic field use either polarity or inclination compasses to determine the field polarity (the north or south direction). Distinguishing the two compass types is a guideline for estimation of the molecular principle of reception and has been achieved for a number of animal groups, with the exception of insects. A standard diagnostic method to distinguish a compass type is based on reversing the vertical component of the geomagnetic field, which leads to the opposite reactions of animals with two different compass types. In the present study, adults of the mealworm beetle Tenebrio molitor were tested by means of a two-step laboratory test of magnetoreception. Beetles that were initially trained to memorize the magnetic position of the light source preferred, during the subsequent test, this same direction, pursuant geomagnetic cues only. In the following step, the vertical component was reversed between the training and the test. The beetles significantly turned their preferred direction by 180°. Our results brought until then unknown original findings that insects, represented here by the T. molitor species, use—in contrast to another previously researched Arthropod, spiny lobster—the inclination compass.

Drell-Yan measurement at COMPASS: a place to test the TMD PDFs universality

For the first time ever, the COMPASS experiment (CERN, SPS) collected in 2015 Drell-Yan (DY) data using a 190 GeV/ c pion beam on a transversely polarized NH3 target. The azimuthal modulations of the DY cross-section give access to the set of transverse momentum dependent (TMD) parton distribution functions (PDFs), which describe the spin structure of the nucleon. Those PDFs were already measured in semi-inclusive deep inelastic scattering (SIDIS) by several experiments and especially COMPASS, which dedicated several campaigns between 2002 and 2010 to measure spin (in)dependent azimuthal asymmetries using a 160 GeV/ c polarized muon beam on a transversely polarized 6LiD or NH3 target. A key interest of extracting those TMD PDFs from different processes is to check the universality and the process-dependent features of TMD PDFs. In this aim, COMPASS is a unique place to test the predicted sign-change of the TMD PDFs using a similar experimental setup and comparable kinematic domain. The main focus of this talk will be set on the physics aspects of the COMPASS polarized Drell-Yan program and related SIDIS results. on behalf of the COMPASS collaboration.

Empathy and compassion are important catalysts for the healing process, but some research suggests their decline during training and practice. Compassion involves recognition, understanding, emotional resonance and empathic concern for another's concerns, distress, pain and suffering, coupled with their acknowledgement, and motivation and relational action to ameliorate these conditions. Neuroscientists have identified neural networks that generate shared representations of directly experienced and observed feelings, sensations and actions. When shared representations evoke empathic concern or compassion for another's painful situation, humans experience altruistic motivation to help. The resulting behaviours are associated with activation of areas in the brain associated with affiliation and reward. Activation of these neural networks is sensitive to multiple inter- and intrapersonal influences. These include the ability to focus one's attention, the ability to receive and accurately interpret input about distress, the perspective one adopts in order to understand another's experience, self-other boundary awareness, the degree to which one values another's welfare, the ability to recognise and regulate one's own emotions, the ability to attend to one's own wellbeing through self-care and self-compassion, effective communication skills, reflection and meta-cognition. Current research suggests that compassion can be modulated through education and training and is associated with positive emotions, a sense of affiliation, reward and prosocial behaviours. A compassion process model and framework with examples of educational goals, interventions and resources for curriculum development are described. However, education must be aligned with changes in clinical practice to sustain compassionate care. © 2016 John Wiley & Sons Ltd.

Within-person changes in mindfulness and self-compassion predict enhanced emotional well-being in healthy, but stressed adolescents.

Galla, Brian M

2016-06-01

Meditation training programs for adolescents are predicated on the assumptions that mindfulness and self-compassion can be directly cultivated, and further, that doing so is beneficial for emotional well-being. Yet, very little research with adolescents has tested these assumptions directly. In the current study, I examined longitudinal relationships between changes in mindfulness and self-compassion and changes in emotional well-being among healthy, but stressed adolescents who participated in five-day, intensive meditation retreats. Immediately before and after the retreats, and then three months later, 132 adolescents (Mage = 16.76 years, 61% female) completed questionnaires measuring mindfulness, self-compassion, and emotional well-being. Repeated measures ANOVA showed adolescents improved in mindfulness, self-compassion, and all indices of emotional well-being immediately following the retreat (Cohen's d = |0.39-1.19|), and many of these improvements were maintained three months later (Cohen's d = |0.04-0.68|). Further, multilevel growth curve analyses with time-varying covariates indicated within-person changes in self-compassion predicted enhanced emotional well-being more consistently than within-person changes in mindfulness. Specifically, increases in self-compassion predicted reductions in perceived stress, rumination, depressive symptoms, and negative affect, and conversely, increases in positive affect and life satisfaction (pseudo-R(2) variance explained = 5.9% and 15.8%, ps < 0.01).

Bluth, Karen; Gaylord, Susan A.; Campo, Rebecca A.; Mullarkey, Michael C.; Hobbs, Lorraine

2015-01-01

The aims of this mixed-method pilot study were to determine the feasibility, acceptability, and preliminary psychosocial outcomes of “Making Friends with Yourself: A Mindful Self-Compassion Program for Teens” (MFY), an adaptation of the adult Mindful Self-Compassion program. Thirty-four students age 14–17 enrolled in this waitlist controlled crossover study. Participants were randomized to either the waitlist or intervention group and administered online surveys at baseline, after the first cohort participated in the intervention, and after the waitlist crossovers participated in the intervention. Attendance and retention data were collected to determine feasibility, and audiorecordings of the 6-week class were analyzed to determine acceptability of the program. Findings indicated that MFY is a feasible and acceptable program for adolescents. Compared to the waitlist control, the intervention group had significantly greater self-compassion and life satisfaction and significantly lower depression than the waitlist control, with trends for greater mindfulness, greater social connectedness and lower anxiety. When waitlist crossovers results were combined with that of the first intervention group, findings indicated significantly greater mindfulness and self-compassion, and significantly less anxiety, depression, perceived stress and negative affect post-intervention. Additionally, regression results demonstrated that self-compassion and mindfulness predicted decreases in anxiety, depression, perceived stress, and increases in life satisfaction post-intervention. MFY shows promise as a program to increase psychosocial wellbeing in adolescents through increasing mindfulness and self-compassion. Further testing is needed to substantiate the findings.

Self-compassion, pain, and breaking a social contract.

PubMed

Purdie, Fiona; Morley, Stephen

2015-11-01

Self-compassion is the ability to respond to one's failures, shortcomings, and difficulties with kindness and openness rather than criticism. This study, which might be regarded as a proof-of-concept study, aimed to establish whether self-compassion is associated with expected emotional responses and the likelihood of responding with problem solving, support seeking, distraction, avoidance, rumination, or catastrophizing to unpleasant self-relevant events occurring in 3 social contexts. Sixty chronic pain patients were presented with 6 vignettes describing scenes in which the principal actor transgressed a social contract with negative interpersonal consequences. Vignettes represented 2 dimensions: (1) whether pain or a nonpain factor interrupted the fulfillment of the contract and (2) variation in the social setting (work, peer, and family). The Self-Compassion Scale was the covariate in the analysis. Higher levels of self-compassion were associated with significantly lower negative affect and lower reported likelihood of avoidance, catastrophizing, and rumination. Self-compassion did not interact with pain vs nonpain factor. Work-related vignettes were rated as more emotional and more likely to be associated with avoidance, catastrophizing, and rumination and less likelihood of problem solving. The findings suggest that self-compassion warrants further investigation in the chronic pain population both regarding the extent of its influence as a trait and in terms of the potential to enhance chronic pain patients' ability to be self-compassionate, with a view to its therapeutic utility in enhancing psychological well-being and adjustment. Limitations regarding the possible criterion contamination and the generalizability of vignette studies are discussed.

Purpose: The purpose of this study was to validate the advent of COMPASS 3D dosimetry as a routine pre treatment verification tool with commercially available CMS Monaco and Oncentra Masterplan planning system. Methods: Twenty esophagus patients were selected for this study. All these patients underwent radical VMAT treatment in Elekta Linac and plans were generated in Monaco v5.0 with MonteCarlo(MC) dose calculation algorithm. COMPASS 3D dosimetry comprises an advanced dose calculation algorithm of collapsed cone convolution(CCC). To validate CCC algorithm in COMPASS, The DICOM RT Plans generated using Monaco MC algorithm were transferred to Oncentra Masterplan v4.3 TPS. Only finalmore » dose calculations were performed using CCC algorithm with out optimization in Masterplan planning system. It is proven that MC algorithm is an accurate algorithm and obvious that there will be a difference with MC and CCC algorithms. Hence CCC in COMPASS should be validated with other commercially available CCC algorithm. To use the CCC as pretreatment verification tool with reference to MC generated treatment plans, CCC in OMP and CCC in COMPASS were validated using dose volume based indices such as D98, D95 for target volumes and OAR doses. Results: The point doses for open beams were observed <1% with reference to Monaco MC algorithms. Comparisons of CCC(OMP) Vs CCC(COMPASS) showed a mean difference of 1.82%±1.12SD and 1.65%±0.67SD for D98 and D95 respectively for Target coverage. Maximum point dose of −2.15%±0.60SD difference was observed in target volume. The mean lung dose of −2.68%±1.67SD was noticed between OMP and COMPASS. The maximum point doses for spinal cord were −1.82%±0.287SD. Conclusion: In this study, the accuracy of CCC algorithm in COMPASS 3D dosimetry was validated by compared with CCC algorithm in OMP TPS. Dose calculation in COMPASS is feasible within < 2% in comparison with commercially available TPS algorithms.« less

Photodetectors and front-end electronics for the LHCb RICH upgrade

NASA Astrophysics Data System (ADS)

Cassina, L.; LHCb RICH

2017-12-01

The RICH detectors of the LHCb experiment provide identification of hadrons produced in high energy proton-proton collisions in the LHC at CERN over a wide momentum range (2-100 GeV/c). Cherenkov light is collected on photon detector planes sensitive to single photons. The RICH will be upgraded (in 2019) to read out every bunch crossing, at a rate of 40 MHz. The current hybrid photon detectors (HPD) will be replaced with multi-anode photomultiplier tubes (customisations of the Hamamatsu R11265 and the H12699 MaPMTs). These 8×8 pixel devices meet the experimental requirements thanks to their small pixel size, high gain, negligible dark count rate (∼50 Hz/cm2) and moderate cross-talk. The measured performance of several tubes is reported, together with their long-term stability. A new 8-channel front-end chip, named CLARO, has been designed in 0.35 μm CMOS AMS technology for the MaPMT readout. The CLARO chip operates in binary mode and combines low power consumption (∼1 mW/Ch), wide bandwidth (baseline restored in ⩽ 25 ns) and radiation hardness. A 12-bit digital register permits the optimisation of the dynamic range and the threshold level for each channel and provides tools for the on-site calibration. The design choices and the characterization of the electronics are presented.

Neural mechanisms in insect navigation: polarization compass and odometer.

PubMed

Labhart, Thomas; Meyer, Eric P

2002-12-01

Insect navigation relies on path integration, a procedure by which information about compass bearings pursued and distances travelled are combined to calculate position. Three neural levels of the polarization compass, which uses the polarization of skylight as a reference, have been analyzed in orthopteran insects. A group of dorsally directed, highly specialized ommatidia serve as polarization sensors. Polarization-opponent neurons in the optic lobe condition the polarization signal by removing unreliable and irrelevant components of the celestial stimulus. Neurons found in the central complex of the brain possibly represent elements of the compass output. The odometer for measuring travelling distances in honeybees relies on optic flow experienced during flight, whereas desert ants most probably use proprioreceptive cues.

Research has identified the experience of shame as a relevant predictor of depressive symptoms. Building upon resilience theory, this is the first study to investigate if self-compassion and/or contingent self-worth (i.e., family support and God's love) mediate the link between shame and depressive symptoms. Participants were 109 African Americans, within the age range of 18 and 64, who sought service following a suicide attempt from a public hospital that serves mostly low-income patients. Findings suggest that shame was related to depressive symptoms through self-compassion but not through contingent self-worth, underscoring the significant role that self-compassion plays in ameliorating the aggravating effect of shame on depressive symptoms. Results highlight the value of incorporating self-compassion training into interventions for suicidal African Americans in an effort to reduce the impact of shame on their depressive symptoms and ultimately their suicidal behavior and as a result enhance their capacity for resilience.

Sun compass integration of skylight cues in migratory monarch butterflies.

PubMed

Heinze, Stanley; Reppert, Steven M

2011-01-27

Migrating monarch butterflies (Danaus plexippus) use a time-compensated sun compass to navigate from eastern North America to their overwintering grounds in central Mexico. Here we describe the neuronal layout of those aspects of the butterfly's central complex likely to establish part of the internal sun compass and find them highly homologous to those of the desert locust. Intracellular recordings from neurons in the monarch sun compass network reveal responses tuned to specific E-vector angles of polarized light, as well as azimuth-dependent responses to unpolarized light, independent of spectral composition. The neural responses to these two stimuli in individual neurons are mediated through different regions of the compound eye. Moreover, these dual responses are integrated to create a consistent representation of skylight cues in the sun compass throughout the day. The results advance our understanding of how ambiguous sensory signals are processed by the brain to elicit a robust behavioral response. © 2011 Elsevier Inc. All rights reserved.

Celestial orientation with the sun not in view: lizards use a time-compensated sky polarization compass.

2014-04-01

The present investigation was aimed at testing whether the lizard sky polarization compass is time compensated. For this purpose, ruin lizards, Podarcis sicula, were both trained and tested for orientation inside a Morris water maze under clear skies with the sun not in view. During training, lizards showed a striking bimodal orientation along the training axis, demonstrating their capability of determining the symmetry plane of the sky polarization pattern and thus the use of polarization information in orientation. After reaching criteria, lizards were kept 7 days in a 6-h fast clock-shift treatment and then released with the sun not in view. Six-hour clock-shifted lizards showed a bimodal distribution of directional choices, which was oriented perpendicularly to the training axis, as it was expected on the basis of the clock-shift. The results show that the only celestial diurnal compass mechanism that does not need a direct vision of the sun disk (i.e., the sky polarization compass) is a time-compensated compass.

Orientation in birds. The sun compass.

PubMed

Schmidt-Koenig, K; Ganzhorn, J U; Ranvaud, R

1991-01-01

The sun compass was discovered by G. Kramer in caged birds showing migratory restlessness. Subsequent experiments with caged birds employing directional training and clock shifts, carried out by Hoffman and Schmidt-Koenig, showed that the sun azimuth is used, and the sun altitude ignored. In the laboratory, McDonald found the accuracy to be +/- 3 degrees(-)+/- 5 degrees. According to Hoffmann and Schmidt-Koenig, caged birds trained at medium northern latitudes were able to allow for the sun's apparent movement north of the arctic circle, but not in equatorial and trans-equatorial latitudes. In homing experiments, and employing clock shifts, Schmidt-Koenig demonstrated that the sun compass is used by homing pigeons during initial orientation. This finding is the principal evidence for the existence of a map-and-compass navigational system. Pigeons living in equatorial latitudes utilize the sun compass even under the extreme solar conditions of equinox, achieving angular resolution of about 3 degrees in homing experiments. According to preliminary analyses, the homing pigeons' ephemerides are retarded by several weeks (Ranvaud, Schmidt-Koenig, Ganzhorn et al.).

Short-Term Compassion Training Increases Prosocial Behavior in a Newly Developed Prosocial Game

2011-01-01

Compassion has been suggested to be a strong motivator for prosocial behavior. While research has demonstrated that compassion training has positive effects on mood and health, we do not know whether it also leads to increases in prosocial behavior. We addressed this question in two experiments. In Experiment 1, we introduce a new prosocial game, the Zurich Prosocial Game (ZPG), which allows for repeated, ecologically valid assessment of prosocial behavior and is sensitive to the influence of reciprocity, helping cost, and distress cues on helping behavior. Experiment 2 shows that helping behavior in the ZPG increased in participants who had received short-term compassion training, but not in participants who had received short-term memory training. Interindividual differences in practice duration were specifically related to changes in the amount of helping under no-reciprocity conditions. Our results provide first evidence for the positive impact of short-term compassion training on prosocial behavior towards strangers in a training-unrelated task. PMID:21408020

A Deuterated Neutron Detector Array For Nuclear (Astro)Physics Studies

The properties of neutron-rich nuclei are at the forefront of research in nuclear structure, nuclear reactions and nuclear astrophysics. The advent of intense rare isotope beams (RIBs) has opened a new door for studies of systems with very short half-lives and possible fascinating properties. Neutron spectroscopic techniques become increasingly relevant when these neutron rich nuclei are used in a variety of experiments. At Florida State University, we are developing a neutron detector array that will allow us to perform high-resolution neutron spectroscopic studies with stable and radioactive beams. The neutron detection system consists of 16 deuterated organic liquid scintillation detectors with fast response and pulse-shape discrimination capabilities. In addition to these properties, there is the potential to use the structure in the pulse-height spectra to extract the energy of the neutrons and thus produce directly excitation spectra. This type of detector uses deuterated benzene (C6D6) as the liquid scintillation medium. The asymmetric nature of the scattering between a neutron and a deuterium in the center of mass produces a pulse-height spectrum from the deuterated scintillator which contains useful information on the initial energy of the neutron.

The mediating role of self-compassion in the relationship between victimization and psychological maladjustment in a sample of adolescents.

PubMed

Játiva, Raquel; Cerezo, M Angeles

2014-07-01

The objectives of the present study were to analyze the relationship between victimization and psychological maladjustment in adolescents and the role of self-compassion as a mediator in this relationship. The sample was composed of 109 adolescents aged from 15 to 18 years old with poor school performance. The participants filled out a battery of questionnaires made up of: a socio-demographic data questionnaire; the Juvenile Victimization Questionnaire (JVQ); the Youth Self-Report (YSR); and the Self-Compassion Scale (SCS). Results indicated that victimization was positively associated with psychological maladjustment. Moreover, adolescents reporting poly-victimization showed significantly higher level of psychological maladjustment and different types of victimization show different effects on adolescents' psychological maladjustment. Self-compassion partially mediated the relationship between victimization and psychological maladjustment and reduced negative consequences in adolescents who reported having been victimized. Adolescence is a time of development and search for identity in which strengthening personal protective factors could help overcome any traumas experienced. Therefore, developing self-compassion in adolescence could be a good way to help young people recover from bad experiences and protect themselves against future negative experiences. As self-compassion can be improved with practice it could be included in adolescent intervention and prevention programs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Animals that use astronomical cues to orientate must make continuous adjustment to account for temporal changes in azimuth caused by Earth’s rotation. For example, the Monarch butterfly possesses a time-compensated sun compass dependent upon a circadian clock in the antennae. The amphipod Talitrus saltator possesses both a sun compass and a moon compass. We reasoned that the time-compensated compass mechanism that enables solar orientation of T. saltator is located in the antennae, as is the case for Monarch butterflies. We examined activity rhythms and orientation of sandhoppers with antennae surgically removed, or unilaterally occluded with black paint. Removing or painting the antennae did not affect daily activity rhythms or competence to orientate using the sun. However, when tested at night these animals were unable to orientate correctly to the moon. We subsequently measured circadian gene expression in the antennae and brain of T. saltator and show the clock genes period and cryptochrome 2 are rhythmically expressed in both tissues, reminiscent of other arthropods known to possess antennal clocks. Together, our behavioural and molecular data suggest that, T. saltator has anatomically discrete lunar and solar orientation apparatus; a sun compass, likely located in the brain and a moon compass in the antennae.

Compassion fatigue is a problem for many health care providers manifesting as physical, mental, and spiritual exhaustion. Our objective was to evaluate the association between prior combat deployment and compassion fatigue among military emergency medicine providers. We conducted a nonexperimental cross-sectional survey of health care providers assigned to the San Antonio Military Medical Center, Department of Emergency Medicine. We used the Professional Quality of Life Scale V survey instrument that evaluates provider burnout, secondary traumatic stress, and compassion satisfaction. Outcomes included burnout, secondary traumatic stress, and compassion satisfaction raw scores. Scores were compared between providers based on previous combat deployments using two-tailed independent sample t tests and multiple regression models. Surveys were completed by 105 respondents: 42 nurses (20 previously deployed), 30 technicians (11 previously deployed), and 33 physicians (16 previously deployed). No statistically significant differences in burnout, secondary traumatic stress, or compassion satisfaction scores were detected between previously deployed providers versus providers not previously deployed. There was no association between previous combat deployment and emergency department provider burnout, secondary traumatic stress, or compassion satisfaction scores.

Polarized light modulates light-dependent magnetic compass orientation in birds

PubMed Central

Muheim, Rachel; Sjöberg, Sissel; Pinzon-Rodriguez, Atticus

2016-01-01

Magnetoreception of the light-dependent magnetic compass in birds is suggested to be mediated by a radical-pair mechanism taking place in the avian retina. Biophysical models on magnetic field effects on radical pairs generally assume that the light activating the magnetoreceptor molecules is nondirectional and unpolarized, and that light absorption is isotropic. However, natural skylight enters the avian retina unidirectionally, through the cornea and the lens, and is often partially polarized. In addition, cryptochromes, the putative magnetoreceptor molecules, absorb light anisotropically, i.e., they preferentially absorb light of a specific direction and polarization, implying that the light-dependent magnetic compass is intrinsically polarization sensitive. To test putative interactions between the avian magnetic compass and polarized light, we developed a spatial orientation assay and trained zebra finches to magnetic and/or overhead polarized light cues in a four-arm “plus” maze. The birds did not use overhead polarized light near the zenith for sky compass orientation. Instead, overhead polarized light modulated light-dependent magnetic compass orientation, i.e., how the birds perceive the magnetic field. Birds were well oriented when tested with the polarized light axis aligned parallel to the magnetic field. When the polarized light axis was aligned perpendicular to the magnetic field, the birds became disoriented. These findings are the first behavioral evidence to our knowledge for a direct interaction between polarized light and the light-dependent magnetic compass in an animal. They reveal a fundamentally new property of the radical pair-based magnetoreceptor with key implications for how birds and other animals perceive the Earth’s magnetic field. PMID:26811473

Cognition and the compassion deficit: the social psychology of helping behaviour in nursing.

PubMed

Paley, John

2014-10-01

This paper discusses compassion failure and compassion deficits in health care, using two major reports by Robert Francis in the UK as a point of reference. Francis enquired into events at the Mid Staffordshire Hospital between 2005 and 2009, events that unequivocally warrant the description 'appalling care'. These events prompted an intense national debate, along with proposals for significant changes in the regulation of nursing and nurse education. The circumstances are specific to the UK, but the issues are international. I suggest that social psychology provides numerous hints about the mechanisms that might have been involved at Mid Staffs and about the reasons why outsiders are blind to these mechanisms. However, there have been few references to social psychology in the post-Francis debate (the Francis Report itself makes no reference to it at all). It is an enormously valuable resource, and it has been overlooked. Drawing on the social psychology literature, I express scepticism about the idea that there was a compassion deficit among the Mid Staff nurses - the assumption that the appalling care had something to do with the character, attitudes, and values of nurses - and argue that the Francis Report's emphasis on a 'culture of compassion and caring in nurse recruitment, training and education' is misconceived. It was not a 'failure of compassion' that led to the events in Mid Staffs but an interlocking set of contextual factors that are known to affect social cognition. These factors cannot be corrected or compensated for by teaching ethics, empathy, and compassion to student nurses. © 2014 John Wiley & Sons Ltd.

Compassion Satisfaction, Compassion Fatigue, and Burnout in Spain and Brazil: ProQOL Validation and Cross-cultural Diagnosis.

2017-03-01

Palliative care professionals' quality of life has emerged as a growing issue of interest in health care literature, centered on concerns about professionals' compassion within a context of work characterized by pain and death. The aim of this study was threefold: 1) to study the psychometric properties of both the Spanish and the Portuguese versions of the ProQOL scale, by means of confirmatory factor analyses; 2) to offer a diagnosis of compassion satisfaction and compassion fatigue levels of Spanish and Brazilian palliative care professionals; and 3) to compare levels in ProQOL between countries. Two surveys with a cross-sectional design were carried out; 161 Brazilian palliative care professionals and 385 Spanish participated in this study. Confirmatory factor analysis for both the Spanish and the Portuguese versions showed an adequate fit. Reliability estimates were also adequate, with problems with the burnout dimension. Spanish and Brazilian palliative care professionals showed high levels of compassion satisfaction (specially, for the Brazilian samples), medium levels of secondary traumatic stress, and low levels of burnout. Finally, statistically significant differences in Spanish and Brazilian levels of compassion satisfaction and secondary traumatic stress were found, but not in burnout. The ProQOL shows psychometric goodness in its Spanish and Portuguese versions, although some items should be revised. The ProQOL is also useful for diagnosis and is sensitive enough to distinguish nuances as that found between Brazilian and Spanish professionals.

Histone H3 lysine 4 (H3K4) methylation is catalyzed by the highly evolutionarily conserved multiprotein complex known as Set1/COMPASS or MLL/COMPASS-like complexes from yeast to human, respectively. Here we have reconstituted fully functional yeast Set1/COMPASS and human MLL/COMPASS-like complex in vitro and have identified the minimum subunit composition required for histone H3K4 methylation. These subunits include the methyltransferase C-terminal SET domain of Set1/MLL, Cps60/Ash2L, Cps50/RbBP5, Cps30/WDR5, and Cps25/Dpy30, which are all common components of the COMPASS family from yeast to human. Three-dimensional (3D) cryo-EM reconstructions of the core yeast complex, combined with immunolabeling and two-dimensional (2D) EM analysis of the individual subcomplexes reveal a Y-shaped architecture with Cps50 and Cps30 localizing on the top two adjacent lobes and Cps60-Cps25 forming the base at the bottom. EM analysis of the human complex reveals a striking similarity to its yeast counterpart, suggesting a common subunit organization. The SET domain of Set1 is located at the juncture of Cps50, Cps30, and the Cps60-Cps25 module, lining the walls of a central channel that may act as the platform for catalysis and regulative processing of various degrees of H3K4 methylation. This structural arrangement suggested that COMPASS family members function as exo-methylases, which we have confirmed by in vitro and in vivo studies. PMID:22158900

Magnetoreception of the light-dependent magnetic compass in birds is suggested to be mediated by a radical-pair mechanism taking place in the avian retina. Biophysical models on magnetic field effects on radical pairs generally assume that the light activating the magnetoreceptor molecules is nondirectional and unpolarized, and that light absorption is isotropic. However, natural skylight enters the avian retina unidirectionally, through the cornea and the lens, and is often partially polarized. In addition, cryptochromes, the putative magnetoreceptor molecules, absorb light anisotropically, i.e., they preferentially absorb light of a specific direction and polarization, implying that the light-dependent magnetic compass is intrinsically polarization sensitive. To test putative interactions between the avian magnetic compass and polarized light, we developed a spatial orientation assay and trained zebra finches to magnetic and/or overhead polarized light cues in a four-arm "plus" maze. The birds did not use overhead polarized light near the zenith for sky compass orientation. Instead, overhead polarized light modulated light-dependent magnetic compass orientation, i.e., how the birds perceive the magnetic field. Birds were well oriented when tested with the polarized light axis aligned parallel to the magnetic field. When the polarized light axis was aligned perpendicular to the magnetic field, the birds became disoriented. These findings are the first behavioral evidence to our knowledge for a direct interaction between polarized light and the light-dependent magnetic compass in an animal. They reveal a fundamentally new property of the radical pair-based magnetoreceptor with key implications for how birds and other animals perceive the Earth's magnetic field.

Gender role conflict or the negative consequences of male socialization may compromise men's adjustment to prostate cancer by shaping how patients perceive and cope with their illness. Given mixed findings regarding how gender role conflict interacts with emotional approach coping to regulate distress in prostate cancer patients, the present study examined the effects of emotional approach coping, when considered alongside self-compassion, the ability to be kind and understanding of oneself. 92 prostate cancer patients completed questionnaires measuring gender role conflict, emotional approach coping, self-compassion and distress. A moderated mediation model was tested, where emotional approach coping mediated the path between gender role conflict and distress and self compassion moderated paths between (a) gender role conflict and emotional approach coping, and (b) gender role conflict and distress. Results partially supported this model with all study variables predicting distress in the expected directions. Emotional approach coping did not mediate associations between gender role conflict and distress; however, self-compassion did moderate the pathway between these variables. Results indicated that higher levels of self-compassion might protect men from distress related to emasculating aspects of the cancer experience. Further investigation is required to understand how self-compassion interacts with emotionality and subsequently influences distress in prostate cancer patients. To better understand the effectiveness of emotional approach coping in reducing distress in prostate cancer patients, it is recommended that future research accounts for the receptiveness of social environments to men's emotional displays.

The Prevalence of Compassion Fatigue among Veterinary Students in Australia and the Associated Psychological Factors.

PubMed

McArthur, Michelle L; Andrews, Jena R; Brand, Conor; Hazel, Susan J

Compassion fatigue, compassion satisfaction, and other characteristics such as mindfulness and mental health stigma have not been investigated in veterinary students. The aims of this study were twofold: first to determine the prevalence of compassion, satisfaction, burnout, and secondary traumatic stress among Australian veterinary students and second to investigate the association between these factors and self-stigma, coping, empathy, and mindfulness. A cross-sectional online survey consisting of demographic questions and four validated psychological measures sampled 828 students, with a response rate of 31% (255/828). We obtained a usable sample of completed surveys from 193 of 828 (23%) veterinary students from six of the seven Australian veterinary schools. Bivariate correlations and multiple regression analyses were used to examine associations between the psychological predictors and the outcome variables. Approximately 30% of veterinary students were at high risk of burnout, 24% were at high risk of secondary traumatic stress, and 21% reported low compassion satisfaction. High empathic concern, low personal distress, female gender, and employment history at a veterinary clinic were associated with high compassion satisfaction. High dysfunctional coping, low nonjudgmental and acting-with-awareness mindfulness, and lack of previous employment at a veterinary clinic were associated with high burnout. High dysfunctional coping, low acting-with-awareness mindfulness, high self-stigma, and high personal distress were associated with high secondary traumatic stress. As a result of these findings, certain emotional characteristics can be identified as targets for intervention to minimize the frequency and potentially negative impact of compassion fatigue and burnout in veterinary students.

In this pilot study, we sought to investigate the effects of a mindfulness intervention for adolescents on a community sample of teens. Specifically, we explored the effects of mindfulness training on emotional well-being outcomes. Also, we examined the relationship between mindfulness and self-compassion at baseline-predicted outcome measures. This design was a pre-/post-pilot intervention study. Paired t-tests were conducted to examine change in outcome measures before and after the mindfulness intervention. Multiple regression was also conducted to investigate the influence of baseline mindfulness and self-compassion on outcome measures. The study took place after school in a classroom at a local university. Overall 28 adolescents age 10-18 years from two different cohorts participated in this study. Learning to BREATHE, a mindfulness curriculum designed specifically for adolescents and taught in six 1.5h sessions, was implemented. The outcome measures, life satisfaction and perceived stress, were included in an online survey before and after the mindfulness intervention. Results indicated that mindfulness, self-compassion, perceived stress, and life satisfaction improved from pre-intervention to post-intervention. Further, self-compassion (taught within the mindfulness intervention) was negatively related to perceived stress post-intervention while controlling for baseline stress. These findings suggest that mindfulness may be an effective intervention for improving indicators of emotional well-being among an adolescent population. Additionally, self-compassion may be a pathway through which youth can lower stress. Future research should examine self-compassion as a potential factor in promoting emotional well-being.

To explore patient-centred nursing, compassion satisfaction and compassion fatigue from intensive care nurses' perspectives. Compassion satisfaction and compassion fatigue can influence critical care nurses' decisions to either continue or leave the profession, and could impact the compassionate patient-centred nursing care patients receive during their ICU admission. This qualitative research design was informed by Charmaz's Grounded Theory Constructivist methodology. In-depth interviews were conducted with 21 critical care nurses of two ICUs in Australia during 2016. Interview data were analysed using grounded theory processes. Findings reflected positive and negative impacts on critical care nurses' ability to deal compassionately with their patients. Effects on patient-centred nursing and critical care nurses' own well-being were revealed. A core category of "Expectations" emerged, explaining the tension between critical care nurses' biomedical, clinical skills and knowledge versus compassionate, patient-centred nursing care. This tension was clarified and expanded in subcategories of "Life in the Balance," "Passion and Pressure," "Understanding and Advocacy" and "Tenacity and Fragility". Providing patient-centred nursing may enhance critical care nurses' experience of compassion satisfaction, in turn impacting delivery of compassionate patient-centred nursing to generate a virtuous circle. Critical care nurses who feel respected and supported by their management team and colleagues experience feelings of compassion satisfaction, leading to greater engagement and care towards their patient. Systematically addressing critical care nurses' needs to successfully balance biomedical with compassionate nursing care may lead to greater well-being in the critical care nursing workforce and improve patient experience of intensive care. © 2017 John Wiley & Sons Ltd.

Histone H3 lysine 4 (H3K4) methylation is catalyzed by the highly evolutionarily conserved multiprotein complex known as Set1/COMPASS or MLL/COMPASS-like complexes from yeast to human, respectively. Here we have reconstituted fully functional yeast Set1/COMPASS and human MLL/COMPASS-like complex in vitro and have identified the minimum subunit composition required for histone H3K4 methylation. These subunits include the methyltransferase C-terminal SET domain of Set1/MLL, Cps60/Ash2L, Cps50/RbBP5, Cps30/WDR5, and Cps25/Dpy30, which are all common components of the COMPASS family from yeast to human. Three-dimensional (3D) cryo-EM reconstructions of the core yeast complex, combined with immunolabeling and two-dimensional (2D) EM analysis of the individual subcomplexes reveal a Y-shaped architecture with Cps50 and Cps30 localizing on the top two adjacent lobes and Cps60-Cps25 forming the base at the bottom. EM analysis of the human complex reveals a striking similarity to its yeast counterpart, suggesting a common subunit organization. The SET domain of Set1 is located at the juncture of Cps50, Cps30, and the Cps60-Cps25 module, lining the walls of a central channel that may act as the platform for catalysis and regulative processing of various degrees of H3K4 methylation. This structural arrangement suggested that COMPASS family members function as exo-methylases, which we have confirmed by in vitro and in vivo studies.

Psychological practitioners often seek to directly change the form or frequency of clients' maladaptive perfectionist thoughts, because such thoughts predict future depression. Indirect strategies, such as self-compassion interventions, that seek to change clients' relationships to difficult thoughts, rather than trying to change the thoughts directly could be just as effective. This study aimed to investigate whether self-compassion moderated, or weakened, the relationship between high perfectionism and high depression symptoms in both adolescence and adulthood. The present study utilised anonymous self-report questionnaires to assess maladaptive perfectionism, depression, and self-compassion across two samples covering much of the lifespan. Questionnaires were administered in a high school setting for the adolescent sample (Study 1, Mage = 14.1 years, n = 541), and advertised through university and widely online to attract a convenience sample of adults (Study 2, Mage = 25.22 years, n = 515). Moderation analyses revealed that self-compassion reduced the strength of relationship between maladaptive perfectionism and depression in our adolescent Study 1 (β = -.15, p < .001, R2 = .021.) and our adult study 2 (β = -.14, p < .001, R2 = .020). Cross-sectional self-reported data restricts the application of causal conclusions and also relies on accurate self-awareness and willingness to respond to questionnaire openly. The replication of this finding in two samples and across different age-appropriate measures suggests that self-compassion does moderate the link between perfectionism and depression. Self-compassion interventions may be a useful way to undermine the effects of maladaptive perfectionism, but future experimental or intervention research is needed to fully assess this important possibility.

Airport geomagnetic surveys in the United States

The Federal Aviation Administration (FAA) and the United States military have requirements for design, location, and construction of compass calibration pads (compass roses), these having been developed through collaboration with US Geological Survey (USGS) personnel. These requirements are detailed in the FAA Advisory Circular AC 150/5300-13, Appendix 4, and in various military documents, such as Handbook 1021/1, but the major requirement is that the range of declination measured within 75 meters of the center of a compass rose be less than or equal to 30 minutes of arc. The USGS Geomagnetism Group has developed specific methods for conducting a magnetic survey so that existing compass roses can be judged in terms of the needed standards and also that new sites can be evaluated for their suitability as potentially new compass roses. First, a preliminary survey is performed with a total-field magnetometer, with differences over the site area of less than 75nT being sufficient to warrant additional, more detailed surveying. Next, a number of survey points are established over the compass rose area and nearby, where declination is to be measured with an instrument capable of measuring declination to within 1 minute of arc, such as a Gurley transit magnetometer, DI Flux theodolite magnetometer, or Wild T-0. The data are corrected for diurnal and irregular effects of the magnetic field and declination is determined for each survey point, as well as declination range and average of the entire compass rose site. Altogether, a typical survey takes about four days to complete. ?? 2006 Springer.

Interaction of compass sensing and object-motion detection in the locust central complex.

PubMed

Bockhorst, Tobias; Homberg, Uwe

2017-07-01

Goal-directed behavior is often complicated by unpredictable events, such as the appearance of a predator during directed locomotion. This situation requires adaptive responses like evasive maneuvers followed by subsequent reorientation and course correction. Here we study the possible neural underpinnings of such a situation in an insect, the desert locust. As in other insects, its sense of spatial orientation strongly relies on the central complex, a group of midline brain neuropils. The central complex houses sky compass cells that signal the polarization plane of skylight and thus indicate the animal's steering direction relative to the sun. Most of these cells additionally respond to small moving objects that drive fast sensory-motor circuits for escape. Here we investigate how the presentation of a moving object influences activity of the neurons during compass signaling. Cells responded in one of two ways: in some neurons, responses to the moving object were simply added to the compass response that had adapted during continuous stimulation by stationary polarized light. By contrast, other neurons disadapted, i.e., regained their full compass response to polarized light, when a moving object was presented. We propose that the latter case could help to prepare for reorientation of the animal after escape. A neuronal network based on central-complex architecture can explain both responses by slight changes in the dynamics and amplitudes of adaptation to polarized light in CL columnar input neurons of the system. NEW & NOTEWORTHY Neurons of the central complex in several insects signal compass directions through sensitivity to the sky polarization pattern. In locusts, these neurons also respond to moving objects. We show here that during polarized-light presentation, responses to moving objects override their compass signaling or restore adapted inhibitory as well as excitatory compass responses. A network model is presented to explain the variations of these responses that likely serve to redirect flight or walking following evasive maneuvers.

Although the death of a loved one is a devastating family event, little is known about which behaviors positively affect families' perceptions on death pronouncements. The objective of this study was to evaluate the effect of a compassionate death pronouncement on participant-perceived physician compassion, trust in physicians, and emotions. In this randomized, video-vignette study, 92 people (≥50 years) in Tokyo metropolitan area viewed two videos of death pronouncements by an on-call physician with or without compassion-enhanced behaviors, including five components: waiting until the families calm themselves down, explaining that the physician has received a sign-out about information of the patient's condition, performing examination respectfully, ascertaining the time of death with a wristwatch (vs. smartphone), and reassuring the families that the patient did not experience pain. Main outcomes were physician compassion score, trust in physician, and emotions. After viewing the video with compassion-enhanced behaviors compared with the video without them, participants assigned significantly lower compassion scores (reflecting higher physician compassion) (mean 26.2 vs. 36.4, F = 33.1, P < 0.001); higher trust in physician (5.10 vs. 3.00, F = 39.7, P < 0.001); and lower scores for anger (2.49 vs. 3.78, F = 18.0, P < 0.001), sadness (3.42 vs. 3.85, F = 11.8, P = 0.001), fear (1.93 vs. 2.55, F = 15.8, P < 0.001), and disgust (2.45 vs. 3.71, F = 19.4, P < 0.001). To convey compassion on death pronouncement, we recommend that physicians initiate prompt examination, explain that the physician has received a sign-out, perform examination respectfully, ascertain the time of death with a wristwatch, and reassure the families that the patient did not experience pain.

We report the first measurement of the deuterium abundance in cosmic rays above 10 GeV nucleon-1 of kinetic energy. The data were collected by the balloon-borne experiment CAPRICE98, which was flown on 1998 May 28-29 from Fort Sumner, New Mexico. The detector configuration included the NMSU-WiZard/CAPRICE superconducting magnet spectrometer equipped with a gas RICH detector, a silicon-tungsten calorimeter, and a time-of-flight system. By combining the information from the spectrometer and the RICH detector, it was possible to separate deuterons from protons in the kinetic energy range from 12 to 22 GeV nucleon-1. In order to estimate the proton background and the deuteron selection efficiency, we developed an empirical model for the response of the instrument, based on the data collected in this experiment. The analysis procedure is described in this paper, and the result on the absolute flux of deuterium is presented. We found that the deuterium abundance at high energy is consistent with the hypothesis that the propagation mechanism of light nuclei is the same as that of heavier secondary components.

In 2019 the LHCb RICH detector will be upgraded to increase the read out rate from 1 MHz to 40 MHz. As a consequence, the current Hybrid Photon Detectors will have to be replaced. Multi-anode Photomultiplier Tubes (MaPMTs) from Hamamatsu with 64-channels will be used: the 1-in. R13742 and the 2-in. R13743 MaPMTs (custom modifications of the MaPMTs R11625 and R12699). Quality assurance testing of these MaPMTs using custom-developed readout electronics has started. We present the design and realisation of the test facilities to ensure consistency in testing and validation. A total of 3100 units of the R13742 and 450 units of the R13743 will be tested requiring high efficiency and reliability from the test stations. We report on the test programme and protocols, characterising the units and assuring compliance with specifications. First results of testing and detector characterisation will be presented, based on the pre-series production, comprising 54 units of R13742 and 20 units of R13743.

Compassion fatigue is the emotional exhaustion and stress that nurses can feel when caring for terminally ill patients. This can contribute to high nursing turnover rates, result in poor job satisfaction, and lead to decreased ability to provide quality care. Oncology nurses are vulnerable to compassion fatigue because they develop relationships with patients battling life-threatening illnesses, provide end-of-life care, and encounter ethical dilemmas related to cancer treatment.

Unraveling navigational strategies in migratory insects

PubMed Central

Merlin, Christine; Heinze, Stanley; Reppert, Steven M.

2011-01-01

Long-distance migration is a strategy some animals use to survive a seasonally changing environment. To reach favorable grounds, migratory animals have evolved sophisticated navigational mechanisms that rely on a map and compasses. In migratory insects, the existence of a map sense (sense of position) remains poorly understood, but recent work has provided new insights into the mechanisms some compasses use for maintaining a constant bearing during long-distance navigation. The best-studied directional strategy relies on a time-compensated sun compass, used by diurnal insects, for which neural circuits have begun to be delineated. Yet, a growing body of evidence suggests that migratory insects may also rely on other compasses that use night sky cues or the Earth's magnetic field. Those mechanisms are ripe for exploration.

Compassion Fade: Affect and Charity Are Greatest for a Single Child in Need

2014-01-01

Charitable giving in 2013 exceeded $300 billion, but why do we respond to some life-saving causes while ignoring others? In our first two studies, we demonstrated that valuation of lives is associated with affective feelings (self-reported and psychophysiological) and that a decline in compassion may begin with the second endangered life. In Study 3, this fading of compassion was reversed by describing multiple lives in a more unitary fashion. Study 4 extended our findings to loss-frame scenarios. Our capacity to feel sympathy for people in need appears limited, and this form of compassion fatigue can lead to apathy and inaction, consistent with what is seen repeatedly in response to many large-scale human and environmental catastrophes.

The Berkeley Compass Project is a self-formed group of graduate and undergraduate students in the physical sciences at UC Berkeley. Our goals are to improve undergraduate physics education, provide opportunities for professional development, and increase retention of students from populations typically underrepresented in the physical sciences. Graduate students, together with upper-level undergraduates, design and run all Compass programs. We strive to create a community of educators that incorporates best practices from the science education literature. Along the way, we develop experience in curriculum development, fundraising, grant writing, interfacing with university administration, and other aspects of running an effective organization. Our experience in Compass leaves us better poised to be successful researchers, teachers, and mentors.

Sensory bases of navigation.

PubMed

Gould, J L

1998-10-08

Navigating animals need to know both the bearing of their goal (the 'map' step), and how to determine that direction (the 'compass' step). Compasses are typically arranged in hierarchies, with magnetic backup as a last resort when celestial information is unavailable. Magnetic information is often essential to calibrating celestial cues, though, and repeated recalibration between celestial and magnetic compasses is important in many species. Most magnetic compasses are based on magnetite crystals, but others make use of induction or paramagnetic interactions between short-wavelength light and visual pigments. Though odors may be used in some cases, most if not all long-range maps probably depend on magnetite. Magnetitebased map senses are used to measure only latitude in some species, but provide the distance and direction of the goal in others.

The Skylab fire detector was evaluated in a zero gravity environment. To conduct the test, small samples of spacecraft materials were ignited in a 5 psi oxygen-rich atmosphere inside a combustion chamber. The chamber free-floated in the cabin of a C-135 aircraft, as the aircraft executed a Keplerian parabola. Up to 10 seconds of zero-gravity combustion were achieved. The Skylab fire-detector tubes viewed the flames from a simulated distance of 3m, and color movies were taken to record the nature of the fire. The experiments established the unique form of zero-gravity fires for a wide range of materials. From the tube-output data, the alarm threshold and detector time constant were verified for the Skylab Fire Detection System.

Purpose: To cross-validate the MGDR of COMPASS (IBA dosimetry, GmbH, Germany) and OCTAVIUS 4D system (PTW, Freiburg, Germany). Methods: Volumetric-modulated arc plans (5 head-and-neck and 3 prostate) collapsed to 40° gantry on the OCTAVIUS 4D phantom in QA mode on Monaco v5.0 (Elekta, CMS, Maryland Heights, MO) were delivered on a Elekta Agility linac. This study was divided into two parts: (1) error-free measurements by gantry-mounted EvolutionXX 2D array were reconstructed in COMPASS (IBA dosimetry, GmbH, Germany), and by OCTAVIUS 1500 array in Versoft v6.1 (PTW, Freiburg, Germany) to obtain the 3D doses (COM4D and OCTA4D). COM4D and OCTA4D weremore » compared to the raw measurement (OCTA3D) at the same detector plane for which OCTAVIUS 1500 was perpendicular to 0° gantry axis while the plans were delivered at gantry 40°; (2) beam steering errors of energy (Hump=-2%) and symmetry (2T=+2%) were introduced during the delivery of 5 plans to compare the MGDR doses COM4D-Hump (COM4D-2T), OCTA4D-Hump (OCTA4D-2T), with raw doses OCTA3D-Hump (OCTA3D-2T) and with OCTA3D to assess the error reconstruction and detection ability of MGDR tools. All comparisons used Υ-criteria of 2%(local dose)/2mm and 3%/3mm. Results: Averaged Υ passing rates were 85% and 96% for COM4D,and 94% and 99% for OCTA4D at 2%/2mm and 3%/3mm criteria respectively. For error reconstruction, COM4D-Hump (COM4D-2T) showed 81% (93%) at 2%/2mm and 94% (98%) at 3%/3mm, while OCTA4D-Hump (OCTA4D-2T) showed 96% (96%) at 2%/2mm and 99% (99%) at 3%/3mm. For error detection, OCTA3D doses were compared to COM4D-Hump (COM4D-2T) showing Υ passing rates of 93% (93%) at 2%/2mm and 98% (98%), and to OCTA4D-Hump (OCTA4D -2T) showing 94% (99%) at 2%/2mm and 81% (96%) at 3%/3mm, respectively. Conclusion: OCTAVIUS MGDR showed better agreement to raw measurements in both error- and error-free comparisons. COMPASS MGDR deviated from the raw measurements possibly owing to beam modeling uncertainty.« less

Information regarding treatment options and prognosis is essential for patient decision making. Patient perception of physicians as being less compassionate when they deliver bad news might be a contributor to physicians' reluctance in delivering these types of communication. To compare patients' perception of physician compassion after watching video vignettes of 2 physicians conveying a more optimistic vs a less optimistic message, determine patients' physician preference after watching both videos, and establish demographic and clinical predictors of compassion. Randomized clinical trial at an outpatient supportive care center in a cancer center in Houston, Texas, including English-speaking adult patients with advanced cancer who were able to understand the nature of the study and complete the consent process. Actors and patients were blinded to the purpose of the study. Investigators were blinded to the videos observed by the patient. One hundred patients were randomized to observe 2 standardized, roughly 4-minute videos depicting a physician discussing treatment information (more optimistic message vs less optimistic message) with a patient with advanced cancer. Both physicians made an identical number of empathetic statements (5) and displayed identical posture. After viewing each video, patients completed assessments including the Physician Compassion Questionnaire (0 = best, 50 = worst). Patients' perception of physician compassion after being exposed to a more optimistic vs an equally empathetic but less optimistic message. Patients reported significantly better compassion scores after watching the more optimistic video as compared with the less optimistic video (median [interquartile range], 15 [5-23] vs 23 [10-31]; P < .001). There was a sequence effect favoring the second video on both compassion scores (P < .001) and physician preference (P < .001). Higher perception of compassion was found to be associated with greater trust in the medical profession independent of message type: 63 patients observing the more optimistic message ranked the physician as trustworthy vs 39 after the less optimistic message (P = .03). Patients perceived a higher level of compassion and preferred physicians who provided a more optimistic message. More research is needed in structuring less optimistic message content to support health care professionals in delivering less optimistic news. clinicaltrials.gov Identifier: NCT02357108.

Particle accelerators are very complex systems whose accurate description involves a large number of degrees of freedom and requires the inclusion of many physics processes. Building on the success of the SciDAC-1 Accelerator Science and Technology project, the SciDAC-2 Community Petascale Project for Accelerator Science and Simulation (ComPASS) is developing a comprehensive set of interoperable components for beam dynamics, electromagnetics, electron cooling, and laser/plasma acceleration modelling. ComPASS is providing accelerator scientists the tools required to enable the necessarymore » accelerator simulation paradigm shift from high-fidelity single physics process modeling (covered under SciDAC1) to high-fidelity multiphysics modeling. Our computational frameworks have been used to model the behavior of a large number of accelerators and accelerator R&D experiments, assisting both their design and performance optimization. As parallel computational applications, the ComPASS codes have been shown to make effective use of thousands of processors. ComPASS is in the first year of executing its plan to develop the next-generation HPC accelerator modeling tools. ComPASS aims to develop an integrated simulation environment that will utilize existing and new accelerator physics modules with petascale capabilities, by employing modern computing and solver technologies. The ComPASS vision is to deliver to accelerator scientists a virtual accelerator and virtual prototyping modeling environment, with the necessary multiphysics, multiscale capabilities. The plan for this development includes delivering accelerator modeling applications appropriate for each stage of the ComPASS software evolution. Such applications are already being used to address challenging problems in accelerator design and optimization. The ComPASS organization for software development and applications accounts for the natural domain areas (beam dynamics, electromagnetics, and advanced acceleration), and all areas depend on the enabling technologies activities, such as solvers and component technology, to deliver the desired performance and integrated simulation environment. The ComPASS applications focus on computationally challenging problems important for design or performance optimization to all major HEP, NP, and BES accelerator facilities. With the cost and complexity of particle accelerators rising, the use of computation to optimize their designs and find improved operating regimes becomes essential, potentially leading to significant cost savings with modest investment.« less

Acute health care environments can be stressful settings with clinicians experiencing deleterious effects of burnout and compassion fatigue affecting their mental health. Subsequently, the quality of patient care and outcomes may be threatened if clinicians experience burnout or compassion fatigue. Therefore, the aim of this descriptive, cross-sectional study was to evaluate the prevalence of burnout and compassion fatigue among burn clinicians in Israel. Fifty-five clinicians from Burns, Plastics and Reconstruction Surgery and Intensive Care completed four validated surveys to assess burnout (Maslach Burnout Inventory), depression (PRIME-MD), health-related quality of life (SF-8), and compassion fatigue (Professional Quality of Life version 5). Burn clinicians were compared with Plastics and Reconstruction Surgery and Intensive Care clinicians. This study identified a high prevalence of burnout (38.2%) among Intensive Care, Plastics and Reconstruction and Burns clinicians, with Burns clinicians having a greatly increased prevalence of burnout compared to Intensive Care clinicians (OR =24.3, P=0.017). Additional factors contributing to compassion fatigue were those without children (P=0.016), divorced (P=0.035), of a younger age (P=0.019), and a registered nurse (P=0.05). Burnout increased clinicians’ risk of adverse professional and personal outcomes and correlated with less free time (P<0.001), increased risk of experiencing work-home disputes (P=0.05), increased depression (P=0.001) and decreased career satisfaction (P=0.01). Burnout was also associated with higher physical (mean difference =3.8, P<0.001) and lower mental (mean difference =−3.5, P<0.001) Quality of Life scores. Caring for burn survivors can lead to burnout, compassion fatigue, and vicarious trauma. Identifying strategies to abate these issues is essential to ensure improved clinicial environments and patient outcomes. PMID:28670122

Self-compassion moderates the perfectionism and depression link in both adolescence and adulthood

2018-01-01

Background Psychological practitioners often seek to directly change the form or frequency of clients’ maladaptive perfectionist thoughts, because such thoughts predict future depression. Indirect strategies, such as self-compassion interventions, that seek to change clients’ relationships to difficult thoughts, rather than trying to change the thoughts directly could be just as effective. This study aimed to investigate whether self-compassion moderated, or weakened, the relationship between high perfectionism and high depression symptoms in both adolescence and adulthood. Methods The present study utilised anonymous self-report questionnaires to assess maladaptive perfectionism, depression, and self-compassion across two samples covering much of the lifespan. Questionnaires were administered in a high school setting for the adolescent sample (Study 1, Mage = 14.1 years, n = 541), and advertised through university and widely online to attract a convenience sample of adults (Study 2, Mage = 25.22 years, n = 515). Results Moderation analyses revealed that self-compassion reduced the strength of relationship between maladaptive perfectionism and depression in our adolescent Study 1 (β = -.15, p < .001, R2 = .021.) and our adult study 2 (β = -.14, p < .001, R2 = .020). Limitations Cross-sectional self-reported data restricts the application of causal conclusions and also relies on accurate self-awareness and willingness to respond to questionnaire openly. Conclusions The replication of this finding in two samples and across different age-appropriate measures suggests that self-compassion does moderate the link between perfectionism and depression. Self-compassion interventions may be a useful way to undermine the effects of maladaptive perfectionism, but future experimental or intervention research is needed to fully assess this important possibility.

Effectiveness of Mindfulness Intervention in Reducing Stress and Burnout for Mental Health Professionals in Singapore.

PubMed

Suyi, Yang; Meredith, Pamela; Khan, Asaduzzaman

Stress and burnout have been shown to be a concern among mental health professionals in several countries including Singapore, and can affect quality of care and staff turnover. The aim of this study was to examine the effectiveness of a mindfulness program in increasing mindfulness and compassion, and reducing stress and burnout, among mental health professionals in Singapore. The study utilized data from a prospective pre-post study design with follow-up. A total of 37 mental health professionals participated in the program, which was conducted in three cohorts over nine months. The program consisted of six, two-hour sessions offered once a week over six weeks, and used a range of mindfulness techniques to teach participants to cultivate compassionate and non-judgemental attitudes toward their inner experiences. Data were collected at three stages: pre- and post-intervention, and three months follow-up. Assessments considered mindfulness (five facets mindfulness questionnaire), compassion (self-compassion scale-SF and compassion scale), stress (perceived stress scale-10), and burnout (Oldenburg Burnout inventory). Participants demonstrated significant improvement in four of the five mindfulness facets (observe, describe, non-judge, and non-react) and in compassion levels, and a significant reduction in stress, following intervention. The gains in mindfulness and self-compassion scores were maintained at three months follow-up. No change was observed for burnout variables. Results suggest that mindfulness training was effective in reducing stress and improving mindfulness and compassion, but not decreasing burnout, for this group of mental health professionals in Singapore. Future experimental research with larger samples is warranted to validate the findings of the present study. Copyright © 2017 Elsevier Inc. All rights reserved.

Prevalence, causes and consequences of compassion satisfaction and compassion fatigue in emergency care: a mixed-methods study of UK NHS Consultants.

To estimate prevalence and explore potential causes and consequences of compassion satisfaction and compassion fatigue in UK emergency medicine consultants. A sequential mixed-methods design. Cross-sectional e-survey to all UK NHS emergency medicine consultants (n=1317) including Professional Quality of Life (ProQOL) (compassion satisfaction/fatigue), followed by interviews with consultants scoring above (n=6) and below (n=6) predefined ProQOL thresholds. 681 (52%) consultants responded. Most (98%) reported at least 'average' compassion satisfaction. Higher scores were associated with type of workplace (designated trauma centres faring better) and number of years worked as a consultant (gradually worsen over time, except 20 years onwards when it improves). Consultants with lower (worse) compassion satisfaction scores were more likely to report being irritable with patients or colleagues and reducing their standards of care (a third reported these behaviours at least monthly) and were more likely to intend to retire early (59% had such plans). Key features distinguishing 'satisfied' from 'fatigued' interviewed consultants included having strategies to deal with the high work intensities associated with their role and having positive views of the team within which they worked. The degree of variety in their roles and the ability to maintain empathy for their patients were also distinguishing features between these groups. Findings support an urgent review of workforce and resources in emergency medicine and suggest that a multifactorial approach to identification, prevention and treatment of occupational stress in the workforce is required that considers individual, job and organisational factors, particularly those that impact on perceived control and support at work.

Allen, Ashley Batts; Robertson, Emily; Patin, Gail A

2017-10-01

This study examined the effectiveness of a domestic violence shelter and tested the impact of a self-compassion support group curriculum on outcomes valued by shelters such as autonomy, emotional restoration, and safety. Data were collected from 251 women staying in a domestic violence shelter who had the opportunity to attend a self-compassion support group during their stay. Women completed a pre- and posttest survey assessing self-compassion, empowerment, positive emotion, and perceptions of safety. First, women experienced a positive change ( N = 36) from pretest to posttest across all four outcome variables, suggesting the domestic violence shelter was effective at improving survivors' well-being. Second, participants who attended a self-compassion support group at least once reported more positive posttest scores compared with those who did not attend a group ( N = 79); however, this effect was limited to participants who stayed in shelter a short time. Women who stayed in shelter a longer amount of time experienced more positive posttest scores regardless of group attendance. Although the sample size was limited, analyses directly comparing the traditional shelter support group with the self-compassion support group show that both were equally effective. These findings provide support for shelter effectiveness in terms of improving well-being. They also suggest women who stay in shelter a short period of time may not experience as many shelter benefits unless they attend a support group. Therefore, shelters should consider offering support groups to women very soon after shelter entry. Furthermore, more research is needed to disentangle the benefits of self-compassion interventions over and above a general support group curriculum.

Many insects rely on celestial compass cues such as the polarization pattern of the sky for spatial orientation. In the desert locust, the central complex (CX) houses multiple sets of neurons, sensitive to the oscillation plane of polarized light and thus probably acts as an internal polarization compass. We investigated whether other sky compass cues like direct sunlight or the chromatic gradient of the sky might contribute to this compass. We recorded from polarization-sensitive CX neurons while an unpolarized green or ultraviolet light spot was moved around the head of the animal. All types of neuron that were sensitive to the plane of polarization ( E -vector) above the animal also responded to the unpolarized light spots in an azimuth-dependent way. The tuning to the unpolarized light spots was independent of wavelength, suggesting that the neurons encode solar azimuth based on direct sunlight and not on the sky chromatic gradient. Two cell types represented the natural 90 deg relationship between solar azimuth and zenithal E -vector orientation, providing evidence to suggest that solar azimuth information supports the internal polarization compass. Most neurons showed advances in their tuning to the E -vector and the unpolarized light spots dependent on rotation direction, consistent with anticipatory signaling. The amplitude of responses and its variability were dependent on the level of background firing, possibly indicating different internal states. The integration of polarization and solar azimuth information strongly suggests that besides the polarization pattern of the sky, direct sunlight might be an important cue for sky compass navigation in the locust. © 2018.

Empathy and feelings of guilt experienced by nurses: A cross-sectional study of their role in burnout and compassion fatigue symptoms.

PubMed

Duarte, Joana; Pinto-Gouveia, José

2017-06-01

The main goal of this study was to explore the relationships between empathy, empathy-based pathogenic guilt and professional quality of life (burnout and compassion fatigue). We aim to test a model in which we hypothesize that when empathic feelings are related to pathogenic guilt, burnout and compassion fatigue symptoms may be increased. Empathy is at the core of nursing practice, and has been associated with positive outcomes not only for the healthcare provider but also for the patient. However, empathy is also at the core of guilt feelings that, when excessive and misdirected, can lead to pathogenic guilt beliefs. We focused on two types of empathy-based guilt characterized by excessive responsibility over others' well-being and how these can be related to professional quality of life. This study is a cross-sectional self-report survey. Data were collected during 2014 and 2015. Two hundred ninety-eight nurses from public hospitals in Portugal's north and center region were surveyed. Professional quality of life (burnout and compassion fatigue), empathy, and empathy-based guilt were measured using validated self-report measures. Correlation analyses showed that empathy-based guilt was positively associated with empathy, and with burnout and compassion fatigue. Results from multiple mediation models further indicated when empathy is associated with empathy-based guilt, this leads to greater levels of burnout and compassion fatigue. Given the nature of their work, nurses who experience pathogenic guilt feelings may have compromised well-being, and this should be addressed in training programs aiming at preventing or treating burnout and compassion fatigue.

Simple Summary The VetCompass Australia program collects real-time clinical records from veterinary practices and aggregates them for researchers to interrogate. It delivers Australian researchers sustainable and cost-effective access to authoritative data from hundreds of veterinary practitioners, across Australia and opens up major international collaborative opportunities with related projects in the United Kingdom and elsewhere. Abstract VetCompass Australia is veterinary medical records-based research coordinated with the global VetCompass endeavor to maximize its quality and effectiveness for Australian companion animals (cats, dogs, and horses). Bringing together all seven Australian veterinary schools, it is the first nationwide surveillance system collating clinical records on companion-animal diseases and treatments. VetCompass data service collects and aggregates real-time, clinical records for researchers to interrogate, delivering sustainable and cost-effective access to data from hundreds of veterinary practitioners nationwide. Analysis of these clinical records will reveal geographical and temporal trends in the prevalence of inherited and acquired diseases, identify frequently prescribed treatments, revolutionize clinical auditing, help the veterinary profession to rank research priorities, and assure evidence-based companion-animal curricula in veterinary schools. VetCompass Australia will progress in three phases: (1) roll-out of the VetCompass platform to harvest Australian veterinary clinical record data; (2) development and enrichment of the coding (data-presentation) platform; and (3) creation of a world-first, real-time surveillance interface with natural language processing (NLP) technology. The first of these three phases is described in the current article. Advances in the collection and sharing of records from numerous practices will enable veterinary professionals to deliver a vastly improved level of care for companion animals that will improve their quality of life.

Unlike other places in the western world, Israeli physicians are prone to be exposed to victims of terror and war (soldiers and civilians alike), while in some cases the patients are close friends or relatives. Moreover, in other armed conflict situations (stemming from war or terror), there is a direct threat to the physician's life and his/her family. Among hospital personnel, there is little research concerning the factors associated with aspects of professional quality of life such as burnout, compassion fatigue, and compassion satisfaction. The current study compared a set of risk and protective factors associated with burnout, compassion fatigue, and compassion satisfaction. The sample consisted of 97 physicians who answered a wide battery of questionnaires tapping to the aforementioned factors that served as predictive variables (age, gender, marital status, PTSD symptoms, depressive symptoms, dissociative symptoms, life satisfaction, perceived self-efficacy, perceived family support) using multiple regressions. The study results showed that higher levels of PTSD symptoms were associated with higher levels of compassion fatigue (β = .594; t = 4.419; p <.001). A higher level of life satisfaction was associated with lower burnout (β = -.436; t = -4.293; p <.001). The same results were found also in lower level of perceived family support (β = -.203; t = -2.533; p <.05), and higher level of perceived self-efficacy was associated with higher burnout (β = .298; t = 2.702; p <.01). Finally, a higher level of life satisfaction was associated with higher compassion satisfaction (β = .493; t = 4.419; p <.001). These results may suggest that life satisfaction is a predictor associated with burnout and compassion satisfaction. These results are viewed in light of the importance of life satisfaction as a barrier against burnout and its implication for physicians and hospital policy.

The case for values as a basis for organizational culture.

Brinkley, Ruth W

2013-01-01

At a time when almost every aspect of healthcare is rapidly and dramatically changing, it is important for healthcare leaders to maintain a moral compass--a clear sense of the morals or virtues that guide their decisions. A firmly rooted moral compass inspires, leads, guides, and provides a solid foundation--and some sense of security--for organizations navigating massive or significant transformational changes, such as those required by the Affordable Care Act. In addition, "smaller" changes, such as consolidation, rationalization, and relocation of services, have a strong chance of succeeding in organizations that operate within a moral framework from which the organization can shape its future strategies and make important decisions. Finally, an organization's moral compass guides actions, reactions, and behaviors when unexpected or devastating events occur in the lives of consumers, employees, physicians, business partners, patients, families, and members of the community. The direction toward which its moral compass is pointing determines the types and quality of relationships it has with those key stakeholders, and those individuals and groups come to depend on what they have observed and know to be true about how the organization behaves in certain circumstances. While no organization can predict the future and all of the implications of change, key stakeholder groups need and want to know how they will be treated in the face of such change-whether expected or unexpected. In this sense, every organization must establish ways to evaluate the validity of its moral compass and develop--and adhere to--guidelines that determine how its members will behave, whether in ordinary circumstances; in the face of extraordinary, high-impact situations; or in times of massive transformational change. Above all, executive leaders must always be mindful that their own personal moral compass becomes their organization's moral compass.

Neutron-rich Ba isotopes are expected to exhibit octupolar correlations, reaching their maximum in isotopes around mass A = 146. The odd-A neutron-rich members of this isotopic chain show typical patterns related to non-axially symmetric shapes, which are however less marked compared to even-A ones, pointing to a major contribution from vibrations. In the present paper we present results from a recent study focused on 148-150Cs β-decay performed at the ISOLDE Decay Station equipped with fast-timing detectors. A detailed analysis of the measured decay half-lives and decay scheme of 149Ba is presented, giving a first insight in the structure of this neutron-rich nucleus.

The CERN Super Proton Synchrotron (SPS) has delivered a variety of beams to a vigorous fixed target physics program since 1978. In this paper, we restrict ourselves to the description of a few illustrative examples in the ongoing physics program at the SPS. We will outline the physics aims of the COmmon Muon Proton Apparatus for Structure and Spectroscopy (COMPASS), north area 64 (NA64), north area 62 (NA62), north area 61 (NA61), and advanced proton driven plasma wakefield acceleration experiment (AWAKE). COMPASS studies the structure of the proton and more specifically of its spin. NA64 searches for the dark photon A', which is the messenger for interactions between normal and dark matter. The NA62 experiment aims at a 10% precision measurement of the very rare decay K + → π + νν. As this decay mode can be calculated very precisely in the Standard Model, it offers a very good opportunity to look for new physics beyond the Standard Model. The NA61/SHINE experiment studies the phase transition to Quark Gluon Plasma, a state in which the quarks and gluons that form the proton and the neutron are de-confined. Finally, AWAKE investigates proton-driven wake field acceleration: a promising technique to accelerate electrons with very high accelerating gradients. The Physics Beyond Colliders study at CERN is paving the way for a significant and diversified continuation of this already rich and compelling physics program that is complementary to the one at the big colliders like the Large Hadron Collider.

A pilot study on the effects and feasibility of compassion-focused expressive writing in Day Hospice patients.

Research has found that writing about stress can confer physical and psychological health benefits on participants and that adopting a self-compassionate stance may have additional benefits. This pilot study evaluated a self-compassionate expressive writing intervention in a Day Hospice setting. Thirteen patients with life-limiting illnesses wrote on two occasions about recent stressful experiences. Half also received a self-compassion instruction for their writing. Outcome measures were taken at baseline and one week after the second writing session, and text analysis was used to identify changes in the types of words used, reflecting changes in psychological processes. Patients given the self-compassion instruction increased in their self-soothing and self-esteem in contrast to patients in the stress-only condition. Happiness broadly increased in both groups although reported levels of stress generally increased in patients given the self-compassion instruction but decreased in patients in the stress-only condition. Those given the self-compassion instruction also increased in their use of causal reasoning words across the two writing sessions compared with those in the stress-only condition. Expressive writing appears to be beneficial in patients at a hospice and was viewed as valuable by participants. The inclusion of a self-compassion instruction may have additional benefits and a discussion of the feasibility of implementing expressive writing sessions in a Day Hospice is offered.

Beliefs about Emotions, Depression, Anxiety and Fatigue: A Mediational Analysis.

PubMed

Sydenham, Mia; Beardwood, Jennifer; Rimes, Katharine A

2017-01-01

Beliefs that it is unacceptable to experience or express negative emotions have been found to be associated with various clinical problems. It is unclear how such beliefs, which could be viewed as a form of unhelpful perfectionism about emotions, may contribute to symptomatology. This study investigated two hypotheses: a) greater endorsement of beliefs about the unacceptability of negative emotions will be associated with greater emotional avoidance and lower levels of support-seeking and self-compassion; b) these beliefs about emotions will be associated with higher levels of symptoms of depression, anxiety and fatigue and that this relationship will be mediated by social support-seeking, emotional avoidance and self-compassion. Online questionnaires were completed by 451 community participants. Mediational analyses were undertaken to investigate emotional avoidance, social support-seeking and self-compassion as mediators of the relationship between beliefs about emotions and symptoms of depression, anxiety and fatigue. Beliefs about the unacceptability of negative emotions were significantly associated with more emotional avoidance and less self-compassion and support-seeking. The relationships between beliefs about emotions and depression, anxiety and fatigue were significantly mediated by self-compassion and emotional avoidance but not social support-seeking. Future research should investigate whether interventions that pay particular attention to emotional avoidance and self-compassion, such as mindfulness-based therapy or modified forms of CBT, may be beneficial in reducing distress and fatigue associated with beliefs about the unacceptability of negative emotions.

Empathy in Clinical Practice: How Individual Dispositions, Gender, and Experience Moderate Empathic Concern, Burnout, and Emotional Distress in Physicians

Gleichgerrcht, Ezequiel; Decety, Jean

2013-01-01

To better understand clinical empathy and what factors can undermine its experience and outcome in care-giving settings, a large-scale study was conducted with 7,584 board certified practicing physicians. Online validated instruments assessing different aspects of empathy, distress, burnout, altruistic behavior, emotional awareness, and well-being were used. Compassion satisfaction was strongly associated with empathic concern, perspective taking and altruism, while compassion fatigue (burnout and secondary traumatic stress) was more closely related to personal distress and alexithymia. Gender had a highly selective effect on empathic concern, with women displaying higher values, which led to a wide array of negative and devalued feelings. Years of experience did not influence dispositional measures per se after controlling for the effect of age and gender. Participants who experienced compassion fatigue with little to no compassion satisfaction showed the highest scores on personal distress and alexithymia as well as the strongest indicators of compassion fatigue. Physicians who have difficulty regulating their negative arousal and describing and identifying emotions seem to be more prone to emotional exhaustion, detachment, and a low sense of accomplishment. On the contrary, the ability to engage in self-other awareness and regulate one’s emotions and the tendency to help others, seem to contribute to the sense of compassion that comes from assisting patients in clinical practice.

Overview of the COMPASS results on the nucleon spin

The COMPASS experiment [COMPASS, P. Abbon et al., The COMPASS experiment at CERN, Nucl. Inst. Meth. A577, 455 (2007)] at CERN is one of the leading experiments studying the nucleon spin. These studies are being carried on since 2002, by measuring hadrons produced in deep inelastic scattering (DIS) of 160 GeV/c and 200 GeV/c polarised muons off different polarised targets (NH3 for polarised protons and 6LiD for polarised deuterons). One of the main goals is to determine how the total longitudinal spin projection of the nucleon, 1/2, is distributed among its constituents, quarks and gluons. We review here the recent results on the quark and gluon helicities obtained by COMPASS. The other major goal, whose fulfilment is needed for a complete understanding of the nucleon spin, is the determination of the transverse momentum dependent parton distributions (TMDs). Regarding this topic, the latest results on the Collins and Sivers asymmetries will be shown. The former is sensitive to the transverse spin structure of the nucleon, while the latter reflects the correlations between the quarks transverse momentum and the nucleon spin. This overview will conclude with a summary of the approved plans of COMPASS for the near future: the study of TMDs with a pioneering polarised Drell-Yan experiment and the measurement of generalised parton distributions (GPDs).

U. S. combat veterans of the Iraq and Afghanistan wars have elevated rates of posttraumatic stress disorder (PTSD) compared to the general population. Self-compassion, characterized by self-kindness, a sense of common humanity when faced with suffering, and mindful awareness of suffering, is a potentially modifiable factor implicated in the development and maintenance of PTSD. We examined the concurrent and prospective relationship between self-compassion and PTSD symptom severity after accounting for level of combat exposure and baseline PTSD severity. Participants at baseline assessment were 115 Iraq and Afghanistan war veterans exposed to 1 or more traumatic events during deployment (n = 101 at follow-up). PTSD symptoms were assessed using the Clinician Administered PTSD Scale for DSM-IV at baseline and 12 months. Self-compassion and combat exposure were assessed at baseline via self-report. Self-compassion was associated with baseline PTSD symptoms after accounting for combat exposure (β = −.59; p < .001; ΔR2 = .34; f2 = .67; large effect) and predicted 12-month PTSD symptom severity after accounting for combat exposure and baseline PTSD severity (β = −.24; p = .008; ΔR2 = .03; f2 = .08; small effect). Findings suggest that interventions that increase self-compassion may be beneficial for treating chronic PTSD symptoms among some Iraq and Afghanistan war veterans. PMID:25808565

To evaluate the effectiveness of a Mindfulness and Self-Compassion Program on the levels of stress and burnout in Primary Care health professionals. Randomised, controlled clinical trial. Training in Mindfulness was offered to 1,281 health professionals in Navarra (Spain) Primary Care, and 48 of them accepted. The participants were randomly assigned to groups: 25 to the intervention group, and the remaining 23 to the control group. The Mindfulness and Self-Compassion training program consisted of sessions of 2.5chours/week for 8 weeks. The participants had to attend at least 75% of the sessions and perform a daily practical of 45minutes. The levels of mindfulness, self-compassion, perceived stress, and burnout were measured using four questionnaires before and after the intervention. After the intervention, the scores of the intervention group improved significantly in mindfulness (P<.001); perceived stress (P<.001); self-compassion: self-kindness P<.001, shared humanity P=.004, mindfulness P=.001; and burnout: emotional fatigue (P=.046). The comparison with the control group showed significant differences in mindfulness (P<.001), perceived stress (P<.001), self-kindness (P<.001) and emotional fatigue (P=.032). This work suggests that it may be beneficial to encourage mindfulness and self-compassion practices in the health environment. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

VetCompass Australia is veterinary medical records-based research coordinated with the global VetCompass endeavor to maximize its quality and effectiveness for Australian companion animals (cats, dogs, and horses). Bringing together all seven Australian veterinary schools, it is the first nationwide surveillance system collating clinical records on companion-animal diseases and treatments. VetCompass data service collects and aggregates real-time, clinical records for researchers to interrogate, delivering sustainable and cost-effective access to data from hundreds of veterinary practitioners nationwide. Analysis of these clinical records will reveal geographical and temporal trends in the prevalence of inherited and acquired diseases, identify frequently prescribed treatments, revolutionize clinical auditing, help the veterinary profession to rank research priorities, and assure evidence-based companion-animal curricula in veterinary schools. VetCompass Australia will progress in three phases: (1) roll-out of the VetCompass platform to harvest Australian veterinary clinical record data; (2) development and enrichment of the coding (data-presentation) platform; and (3) creation of a world-first, real-time surveillance interface with natural language processing (NLP) technology. The first of these three phases is described in the current article. Advances in the collection and sharing of records from numerous practices will enable veterinary professionals to deliver a vastly improved level of care for companion animals that will improve their quality of life.

Violence is frequent towards nurses in forensic mental health hospitals. Implications of this high risk environment have not been systematically explored. This paper explores occurrence of symptoms on post traumatic stress and their relationship to professional quality of life. Self report questionnaires assessing symptoms of post traumatic stress and professional quality of life were distributed among psychiatric nurses in a high security forensic psychiatric unit with high frequency of violent behaviour. Relationships between post traumatic stress symptoms, forensic nursing experience, type of ward and compassion satisfaction, burnout and compassion fatigue were explored. The prevalence of post traumatic stress symptoms was low. Low scores were found on compassion satisfaction. Length of psychiatric nursing experience and low scores on compassion satisfaction were correlated to increased post traumatic stress symptoms. Although high violence frequency, low rate of post traumatic stress symptoms and low compassion satisfaction scores was found. High staff/patient ratio and emotional distance between staff and patients are discussed as protective factors.

Guided by an overarching body-related shame regulation framework, the present investigation examined the associations between caregiver eating messages and dimensions of objectified body consciousness and further explored whether self-compassion moderated these links in a sample of 322 U.S. college women. Correlational findings indicated that retrospective accounts of restrictive/critical caregiver eating messages were positively related to body shame and negatively related to self-compassion and appearance control beliefs. Recollections of experiencing pressure to eat from caregivers were positively correlated with body shame and inversely associated with appearance control beliefs. Higher self-compassion was associated with lower body shame and body surveillance. Self-compassion attenuated the associations between restrictive/critical caregiver eating messages and both body surveillance and body shame. Implications for advancing our understanding of the adaptive properties of a self-compassionate self-regulatory style in mitigating recall of familial body-related shaming on the internalized body-related shame regulating processes of body objectification in emerging adulthood are discussed.

Magnetic Orientation in Birds and Other Animals

NASA Astrophysics Data System (ADS)

Wiltschko, Wolfgang

The use of the geomagnetic field for compass orientation is widespread among animals, with two types of magnetic compass mechanisms described: an shape inclination compass in birds, turtles and salamanders and a shape polarity compass in arthropods, fishes and mammals. Additionally, some vertebrates appear to derive positional information from the total intensity and/or inclination of the geomagnetic field. For magnetoreception by animals, two models are currently discussed, the shape Radical Pair model assuming light-dependent processes by specialized photopigments, and the shape Magnetite hypothesis proposing magnetoreception by crystals of magnetite, Fe304. Behavioral experiments with migratory birds, testing them under monochromatic lights and subjecting them to a brief, strong pulse that could reverse the magnetization of magnetite particles, produced evidence for both mechanisms. However, monochromatic lights affect old, experienced and young birds alike, whereas the pulse affects only experienced birds, leaving young, inexperienced birds unaffected. These observations suggest that a radical pair mechanism provides birds with directional information for their innate magnetic compass and a magnetite-based mechanism possibly mediates information about total intensity for indicating position.

Palliative medicine is a rewarding field, but providers encounter patient trauma on a routine basis. Compassion fatigue, marked by burnout, secondary traumatic stress, and low satisfaction may result. However, professionals differ markedly in how they respond to patient trauma. The objective of the current study was to determine whether personality traits of neuroticism and agreeableness relate to aspects of compassion fatigue, after accounting for time spent working in the field. Sixty-six palliative medicine physicians, nurses, social workers, and chaplains completed validated measures of personality traits, compassion fatigue, and work background. Providers who had worked longer reported higher levels of satisfaction and lower levels of burnout. Neuroticism demonstrated strong significant associations with secondary traumatic stress and burnout ( Ps < .001). Agreeableness was significantly and strongly associated with compassion satisfaction ( P < .001). These associations held after accounting for years spent working in the field. Personality traits of neuroticism and agreeableness may convey risk and resilience, respectively, for palliative care professionals. More research is needed to determine if assessing personality traits can help identify providers at risk for adverse reactions to patient trauma.

One of the characteristic action of the physician is the compassion that is a trait of his character, unifying psychological, cultural, sociological, ethnic and intellectuals who channels the cognitive aspect of healing and in particular the reality of a particular patient. Most own medical compassion is what Pellegrino calls its intellectual dimension, which is a form of integrated understanding that enables the achievement of all levels at which the patient is well defined. It is the usual choice, grasp, handle and weigh the uniqueness with which the patient lives the disease. The need for compassion, and the rest of the medical profession's own virtues, returns us once again to the need for the formation of a subject capable and unity between all virtues.

Nursing focuses on meeting physical, social and emotional health-care needs of individuals, families and society. In health care, nurses directly communicate with patients and try to empathize with them. Nurses give care under emotionally intense conditions where the individual undergoes pain and distress. Research is aimed at analysing the correlation of self-compassion and emotional intelligence of nursing students. The population of the research consisted of all the undergraduate students (571 students) of the 2010-2011 fall semester of the department of nursing. An information form, Self-compassion Scale and Emotional Intelligence Assessment Scale were utilized to obtain data for the research. For the assessment of the findings of research, Statistical Package for Social Sciences 16.0 for Windows was utilized for statistical analysis. Results indicated that there is a correlation between self-compassion and emotional intelligence and that emotional intelligence, which includes the individual perceiving one's emotions and using the knowledge one gained from them to function while directing thoughts, actions and professional applications, has positive contributions to the features of nurses with developed self-compassion. © 2013 Wiley Publishing Asia Pty Ltd.

The Self-Compassion Scale is Not Validated in a Buddhist Sample.

The concept of self-compassion originated from Buddhism, but very little is known about the utility and functions of this concept among Buddhists. Four hundred and eleven individuals (179 Buddhists and 232 non-Buddhists) completed the survey packages using the self-compassion scale (SCS; Neff in Self Identity 2(3):223-250, 2003a. doi: 10.1080/15298860309027 ). Confirmatory factor analysis showed that the original six dimensions of the SCS were not replicated by both samples, and further analysis of the intra-correlations within dimensions of SCS and relationships between SCS and other variables showed unexpected results specific to Buddhists. Among Buddhists, the dimensions of self-kindness and common humanity neither showed negative correlations with their opposite dimensions nor were associated with better emotional outcomes. In addition, these two dimensions were not predicted by the regular practice of loving-kindness meditation. This study argued that the ideas of self-compassion reflected in the SCS are theoretically different from the ideas of Buddhism, and further implications for measuring and clinically applying self-compassion were discussed.

Divorce is a highly stressful event, and much remains to be learned about the factors that promote psychological resilience when marriages come to an end. In this study, divorcing adults (N = 109) completed a 4-min stream-of-consciousness recording about their marital separation at an initial laboratory visit. Four judges rated the degree to which participants exhibited self-compassion (defined by self-kindness, an awareness of one's place in shared humanity, and emotional equanimity) in their recordings. Judges evidenced considerable agreement in their ratings of participants' self-compassion, and these ratings demonstrated strong predictive utility: Higher levels of self-compassion at the initial visit were associated with less divorce-related emotional intrusion into daily life at the start of the study, and this effect persisted up to 9 months later. These effects held when we accounted for a number of competing predictors. Self-compassion is a modifiable variable, and if our findings can be replicated, they may have implications for improving the lives of divorcing adults.

Social workers are at risk for experiencing burnout and secondary traumatic stress (STS) as a result of the nature of their work and the contexts within which they work. Little attention has been paid to the factors within a social worker's control that may prevent burnout and STS and increase compassion satisfaction. Empathy, which is a combination of physiological and cognitive processes, may be a tool to help address burnout and STS. This article reports on the findings of a study of social workers (N = 173) that explored the relationship between the components of empathy, burnout, STS, and compassion satisfaction using the Empathy Assessment Index and the Professional Quality of Life instruments. It was hypothesized that higher levels of empathy would be associated with lower levels of burnout and STS, and higher levels of compassion satisfaction. Findings suggest that components of empathy may prevent or reduce burnout and STS while increasing compassion satisfaction, and that empathy should be incorporated into training and education throughout the course of a social worker's career.

Virtual reality has been successfully used to study and treat psychological disorders such as phobias and posttraumatic stress disorder but has rarely been applied to clinically-relevant emotions other than fear and anxiety. Self-criticism is a ubiquitous feature of psychopathology and can be treated by increasing levels of self-compassion. We exploited the known effects of identification with a virtual body to arrange for healthy female volunteers high in self-criticism to experience self-compassion from an embodied first-person perspective within immersive virtual reality. Whereas observation and practice of compassionate responses reduced self-criticism, the additional experience of embodiment also increased self-compassion and feelings of being safe. The results suggest potential new uses for immersive virtual reality in a range of clinical conditions.

Unraveling navigational strategies in migratory insects.

2012-04-01

Long-distance migration is a strategy some animals use to survive a seasonally changing environment. To reach favorable grounds, migratory animals have evolved sophisticated navigational mechanisms that rely on a map and compasses. In migratory insects, the existence of a map sense (sense of position) remains poorly understood, but recent work has provided new insights into the mechanisms some compasses use for maintaining a constant bearing during long-distance navigation. The best-studied directional strategy relies on a time-compensated sun compass, used by diurnal insects, for which neural circuits have begun to be delineated. Yet, a growing body of evidence suggests that migratory insects may also rely on other compasses that use night sky cues or the Earth's magnetic field. Those mechanisms are ripe for exploration.

Vector navigation in desert ants, Cataglyphis fortis: celestial compass cues are essential for the proper use of distance information.

PubMed

Sommer, Stefan; Wehner, Rüdiger

2005-10-01

Foraging desert ants navigate primarily by path integration. They continually update homing direction and distance by employing a celestial compass and an odometer. Here we address the question of whether information about travel distance is correctly used in the absence of directional information. By using linear channels that were partly covered to exclude celestial compass cues, we were able to test the distance component of the path-integration process while suppressing the directional information. Our results suggest that the path integrator cannot process the distance information accumulated by the odometer while ants are deprived of celestial compass information. Hence, during path integration directional cues are a prerequisite for the proper use of travel-distance information by ants.

The 35-ton prototype for the Deep Underground Neutrino Experiment (DUNE) Far Detector is a single-phase liquid argon time projection chamber (LAr-TPC) integrated detector that will take cosmics data for a two month run beginning in February 2016. The 35-ton prototype will characterize DUNE's Far Detector technology performance and provide a sample of real data for DUNE reconstruction algorithms. The 35-ton prototype has two drift volumes of lengths 2.23 m and 0.23 m on either side of its anode plane assembly (APA) and makes use of wire planes with wrapped wires and a photon detection system (PDS) utilizing photon detection panels read out by silicon photomultipliers (SiPMs). Data from the 35-ton LAr detector are expected to provide rich information on scintillation light and charged particle tracks. We present a preliminary analysis of cosmics data taken with the 35-ton detector with a focus on stopping muons.

The CLARA-PRISMA setup is a powerful tool for spectroscopic studies of neutron-rich nuclei produced in multi-nucleon transfer and deep-inelastic reactions. It combines the large acceptance spectrometer PRISMA with the {gamma}-ray array CLARA. At present, the ancillary heavy-ion detector DANTE, based on Micro-Channel Plates to be installed at the CLARA-PRISMA setup, is being constructed at LNL. DANTE will open the possibility of measuring {gamma}-{gamma} Doppler-corrected coincidences for the events outside the acceptance of PRISMA. In this presentation, it is described the heavy-ion detector DANTE, as well as the performances of the first prototype.

This philosophical article utilizes the concept of "the Unspeakable," referring to the creation of biopolitical spaces for nursing in which compassion is rendered severely diminished to impossible. The effect of the Unspeakable in shaping nursing practice is explored in contemporary health care. Local, autobiographical narratives are used to illustrate the effect of the Unspeakable on nursing in both the academic and clinical settings. Alternative strategies for resisting the Unspeakable and promoting compassion as an essential element of effective nursing practice are proposed.

Experiments designed to measure neutrino oscillations also provide major opportunities for discovering very weakly coupled states. In order to produce neutrinos, experiments such as LSND collide thousands of Coulombs of protons into fixed targets, while MINOS and MiniBooNE also focus and then dump beams of muons. The neutrino detectors beyond these beam dumps are therefore an excellent arena in which to look for long-lived pseudoscalars or for vector bosons that kinetically mix with the photon. We show that these experiments have significant sensitivity beyond previous beam dumps, and are able to partially close the gap between laboratory experiments and supernovaemore » constraints on pseudoscalars. Future upgrades to the NuMI beamline and Project X will lead to even greater opportunities for discovery. We also discuss thin target experiments with muon beams, such as those available in COMPASS, and show that they constitute a powerful probe for leptophilic PNGBs.« less

The ANTARES neutrino telescope, located 40 km off the coast of Toulon in the Mediterranean Sea at a mooring depth of about 2475 m, consists of twelve detection lines equipped typically with 25 storeys. Every storey carries three optical modules that detect Cherenkov light induced by charged secondary particles (typically muons) coming from neutrino interactions. As these lines are flexible structures fixed to the sea bed and held taut by a buoy, sea currents cause the lines to move and the storeys to rotate. The knowledge of the position of the optical modules with a precision better than 10 cm is essential for a good reconstruction of particle tracks. In this paper the ANTARES positioning system is described. It consists of an acoustic positioning system, for distance triangulation, and a compass-tiltmeter system, for the measurement of the orientation and inclination of the storeys. Necessary corrections are discussed and the results of the detector alignment procedure are described.

To identify the relationship between professionalism and professional quality of life among oncology nurses working at tertiary hospitals in Korea. Oncology nurses are combined with core competencies and qualities required in cancer patient care. Professionalism that means compassion satisfaction and compassion fatigue is a main concept in problem-solving strategies as motivation. Their satisfaction is representative of professionalism and professional quality of life. However, little research has focused on professionalism and professional quality of life. A cross-sectional study with self-administered questionnaires. A total of 285 nurses from two tertiary hospitals were included. Data collection was undertaken using Korean version of professionalism scale derived from the Hall Professional Inventory Scale and professional quality of life. Data were analysed by spss 21.0 for Windows Program using t-test, anova, and multiple regression. The mean score of professionalism in oncology nurses was 77·98 ± 7·31. The mean professional quality of life score for compassion satisfaction, compassion fatigue and secondary traumatic stress was 33·84 ± 5·62, 28·38 ± 5·36 and 28·33 ± 5·48. Compassion satisfaction was affected by factors of professionalism with an explanatory power of 49·2%. Burnout and secondary traumatic stress were affected by factors of professionalism with an explanatory power of 39·3% and 4·8%. The higher the professionalism leads to the higher the compassion satisfaction, the lower the compassion fatigue. The relationship between professionalism and professional quality of life for a health work environment requires further investigation. Our study supports the idea that enhancing professionalism can increase professional quality of life. It is necessary to develop professionalism by recognised qualifications and applied rewards in advanced nursing organisational culture. Furthermore, compassion satisfaction is increased by continuing ethical and moral education programme for clinical nurses to force professional dedication and encouraging nurses to affiliate themselves with the professional communities. Nurses are connected to professionalism affect the quality of nursing service for patients and professional quality of life for themselves. © 2016 John Wiley & Sons Ltd.

Binge eating disorder (BED) is associated with several psychological and medical problems, such as obesity. Approximately 30% of individuals seeking weight loss treatments present binge eating symptomatology. Moreover, current treatments for BED lack efficacy at follow-up assessments. Developing mindfulness and self-compassion seem to be beneficial in treating BED, although there is still room for improvement, which may include integrating these different but complimentary approaches. BEfree is the first program integrating psychoeducation-, mindfulness-, and compassion-based components for treating women with binge eating and obesity. To test the acceptability and efficacy up to 6-month postintervention of a psychological program based on psychoeducation, mindfulness, and self-compassion for obese or overweight women with BED. A controlled longitudinal design was followed in order to compare results between BEfree (n = 19) and waiting list group (WL; n = 17) from preintervention to postintervention. Results from BEfree were compared from preintervention to 3- and 6-month follow-up. BEfree was effective in eliminating BED; in diminishing eating psychopathology, depression, shame and self-criticism, body-image psychological inflexibility, and body-image cognitive fusion; and in improving obesity-related quality of life and self-compassion when compared to a WL control group. Results were maintained at 3- and 6-month follow-up. Finally, participants rated BEfree helpful for dealing with impulses and negative internal experiences. These results seem to suggest the efficacy of BEfree and the benefit of integrating different components such as psychoeducation, mindfulness, and self-compassion when treating BED in obese or overweight women. The current study provides evidence of the acceptability of a psychoeducation, mindfulness, and compassion program for binge eating in obesity (BEfree); Developing mindfulness and self-compassionate skills is an effective way of diminishing binge eating, eating psychopathology and depression, and increasing quality of life in women with obesity; Integrating psychoeducation, mindfulness, and compassion seem to be effective in diminishing binge eating, with results maintained up to 6-month postintervention.

The CLAS12-RICH hybrid geometry

A Ring-imaging Cherenkov detector (RICH) has been designed for the CLAS12 spectrometer (JLAB, Hall B) in order to increase the particle identification. Among the approved physics program focused upon 3D imaging of the nucleon, some Semi Inclusive Deep Inelastic Scattering experiments (E12-09-007, E12-09-008, E12-09-009) demand an efficient kaon identification across the momentum range from 3 to 8 GeV/c. The detector exploits a novel elaborated hybrid geometry based on a complex focusing mirror system that will reduce the area instrumented with photon detectors. For forward scattered particles (θ <12°) with momenta p = 3-8 GeV/c, a proximity imaging method with direct Cherenkov light detection will be used. For larger angles of 12° < θ <35° and momenta of p = 3-6 GeV/c, the Cherenkov light will be focused by a spherical mirror, undergo two further passes through the aerogel radiator and will be reflected from planar mirrors before detection. A carefully study on reflections has been performed considering microscopic and macroscopic effects. In addition, a new feature has been introduced in the CLAS12 simulation software in order to generate the geometry of the detector by using a computer-aided design (CAD) file for an accurate geometrical description.

Cerenkov technology is often the optimal choice for particle identification in high energy particle collision applications. Typically, the most challenging regime is at high pseudorapidity (forward) where particle identification must perform well at high laboratory momenta. For the upcoming electron ion collider (EIC), the physics goals require hadron (π, K, p) identification up to ~50 GeV/c. In this region Cerenkov ring-imaging (RICH) is the most viable solution. The speed of light in a radiator medium is inversely proportional to the refractive index. Hence, for particle identification (PID) reaching out to high momenta a small index of refraction is required. Unfortunately,more » the lowest indices of refraction also result in the lowest light yield ([(dNγ)/dx] ∝ sin2(θC)) driving up the radiator length and thereby the overall detector cost. In this paper we report on a successful test of a compact RICH detector (1 meter radiator) capable of delivering in excess of 10 photoelectrons per ring with a low index radiator gas (CF4). The detector concept is a natural extension of the PHENIX hadron-blind detector (HBD) achieved by adding focusing capability at low wavelength and adequate gain for high efficiency detection of single-electron induced avalanches. Our results indicate that this technology is indeed a viable choice in the forward direction of the EIC. The setup and results are described within.« less

Measurement of the most exotic beta-delayed neutron emitters at N=50 and N=126

Beta-delayed neutron (βn)-emission will be the dominant decay mechanism of neutron-rich nuclei and plays an important role in the stellar nucleosynthesis of heavy elements in the ``r process''. It leads to a detour of the material β-decaying back to stability and the released neutrons increase the neutron-to-seed ratio, and are re-captured during the freeze-out phase and thus influence the final solar r-abundance curve. Thus the neutron branching ratio of very neutron-rich isotopes is a crucial parameter in astrophysical simulations. In addition, β-decay half-lives can be deduced from the time-dependent detection of βn's. I will talk about two recent experimental campaigns. The neutron detector BELEN was used at GSI Darmstadt to measure half-lives and neutron-branching ratios of the heaviest presently accessible βn-emitters at N=126. For isotopes between 204Au and 220Bi nine half-lives and eight neutron-branching ratios were measured for the first time and provide an important input for benchmarking theoretical models in this mass region. Its successor is the BRIKEN detector (``Beta-delayed neutron measurements at RIKEN for nuclear structure, astrophysics, and applications''), the most efficient neutron detector used so far for nuclear structure studies. In conjunction with two clover detectors and the ``Advanced Implantation Detector Array'' (AIDA) the setup has been used a few months ago to measure the most neutron-rich isotopes around 78Ni, 132Sn, and the Rare Earth Region. Some preliminary results are shown from the campaign covering the 78Ni region where the neutron-branching ratio of 78Ni and 28 more isotopes were measured for the first time, as well as the half-lives of 20 isotopes. The BRIKEN campaign aims to (re-)measure almost all βn-emitters between 76Co and 167Eu, many of them for the first time. An extension of the campaign to lighter masses is planned.
