The article analyzes the aesthetic changes which were introduced as regards the historic barracks in Polish cities from 1918 to the present day. The purpose of the analysis was to determine certain periods in history and to assign characteristic forms of initiatives in reference to the post-military objects to the aforementioned periods. The results of the research served as foundation for establishing three periods: 1) 1918-1939, 2) 1945-1989, 3) after 1989, which were determined in reference to typical types of approach towards the modernization of barrack buildings, conditioned by Poland’s political and economic situation. Consequently, the aesthetics of the modernization period characteristic for particular time frames were indicated-the “signs of time” readable in the architecture, referring to periods as follows: 1) symbols of Polishness, associated with regained independence - sculptures, statues, new buildings in contrast with the barracks remaining after the partition, 2) socialistic economy - using barrack as construction resource, utilitarian approach - adaptation to serve new civil functions, often for the needs of production technology, combination of historical and industrial forms, such initiatives on many occasions led to the moral degradation of former militarian districts 3) market economy - constructing new, positive identity and function of barracks buildings confirmed by the tactical changes in their architectural form.

Thomas Jefferson has long fascinated Americans. Even though Jefferson biographer Merrill Peterson once termed Jefferson "impenetrable," a host of recent scholars have tried to penetrate the "inner Jefferson" in an attempt to make him "more vital to people." Trying to understand Jefferson, one could argue, is akin to trying to understand America,…

Strategic acquisitions by academic medical centers: the Jefferson experience as operational paradigm.

As capital investments in the health care industry have changed in popularity, mergers and acquisitions of and by hospitals have created supersystems of health care that are based on the assumption that economies of scale offer greater protection from a variety of forces. The acquisition of West Park (Jefferson Park) Hospital by Thomas Jefferson University and the infusion of Jefferson management into Methodist Hospital have provided the institution with unique opportunities to broaden its population base for acute care admissions and to permit greater diversification within the entire health care market.

Kak, Vivek

2007-09-01

The presence of a vast cohort of individuals in semi-confined settings such as cruise ships, military barracks, and college dormitories is often accompanied by an increase in the risk of particular infections. These are often gastrointestinal infections on cruise ships and respiratory pathogens that are easily transmitted in the barrack and dormitory setting. The control of these infections involves attention to good personal hygiene, safe food and water handling, and use of vaccines to prevent vaccine-preventable diseases.

Influenza A viruses that cause highly pathogenic avian influenza (HPAI) also infect humans. In many developing countries such as Ghana, poultry and humans live in close proximity in both the general and military populations, increasing risk for the spread of HPAI from birds to humans. Respiratory infections such as influenza are especially prone to rapid spread among military populations living in close quarters such as barracks making this a key population for targeted avian influenza surveillance and public health education. Twelve military barracks situated in the coastal, tropical rain forest and northern savannah belts of the country were visited and the troops and their families educated on pandemic avian influenza. Attendants at each site was obtained from the attendance sheet provided for registration. The seminars focused on zoonotic diseases, influenza surveillance, pathogenesis of avian influenza, prevention of emerging infections and biosecurity. To help direct public health policies, a questionnaire was used to collect information on animal populations and handling practices from 102 households in the military barracks. Cloacal and tracheal samples were taken from 680 domestic and domesticated wild birds and analysed for influenza A using molecular methods for virus detection. Of the 1028 participants that took part in the seminars, 668 (65%) showed good knowledge of pandemic avian influenza and the risks associated with its infection. Even though no evidence of the presence of avian influenza (AI) infection was found in the 680 domestic and wild birds sampled, biosecurity in the households surveyed was very poor. Active surveillance revealed that there was no AI circulation in the military barracks in April 2011. Though participants demonstrated good knowledge of pandemic avian influenza, biosecurity practices were minimal. Sustained educational programs are needed to further strengthen avian influenza surveillance and prevention in military barracks.

Brazilian version of the Jefferson Scale of Empathy: psychometric properties and factor analysis

PubMed Central

2012-01-01

Background Empathy is a central characteristic of medical professionalism and has recently gained attention in medical education research. The Jefferson Scale of Empathy is the most commonly used measure of empathy worldwide, and to date it has been translated in 39 languages. This study aimed to adapt the Jefferson Scale of Empathy to the Brazilian culture and to test its reliability and validity among Brazilian medical students. Methods The Portuguese version of the Jefferson Scale of Empathy was adapted to Brazil using back-translation techniques. This version was pretested among 39 fifth-year medical students in September 2010. During the final fifth- and sixth-year Objective Structured Clinical Examination (October 2011), 319 students were invited to respond to the scale anonymously. Cronbach’s alpha, exploratory factor analysis, item-total correlation, and gender comparisons were performed to check the reliability and validity of the scale. Results The student response rate was 93.7% (299 students). Cronbach’s coefficient for the scale was 0.84. A principal component analysis confirmed the construct validity of the scale for three main factors: Compassionate Care (first factor), Ability to Stand in the Patient’s Shoes (second factor), and Perspective Taking (third factor). Gender comparisons did not reveal differences in the scores between female and male students. Conclusions The adapted Brazilian version of the Jefferson Scale of Empathy proved to be a valid, reliable instrument for use in national and cross-cultural studies in medical education.

Background Acute respiratory infections (ARIs) are the leading cause of acute morbidity and lost work time in the United States. Few studies have looked at building design and transmission of ARIs. Objectives This study explores the association of ventilation design, room occupancy numbers, and training week with ARI rates in Army Basic Combat Training barracks. Methods This observational study captured the overall incidence of ARI in a cohort of 16,258 individuals attending basic combat training at Fort Jackson, South Carolina. Results ARI risk was higher among trainees living in the 60-person room barracks compared with those living in 8-person rooms, which increased rapidly for the first few weeks of training and then declined to baseline. Conclusions Findings support direct contact as primary ARI transmission mode in this study population based on observed lower ARI risk in smaller room barracks and similar risk in large room barracks despite heating, ventilation, and air conditioning system variability.

Mohr, Peter D

2017-05-01

Miss Davison was a medical artist at the Manchester Royal Infirmary and the University of Manchester from around 1918 until her retirement in 1957. She illustrated books and scientific papers on anthropology, anatomy and surgery, and became well known for her striking pictures produced by the 'Ross board technique'- a difficult process that she helped pioneer from the 1930s and which forms the bulk of the work she undertook for neurosurgeon Geoffrey Jefferson during the 1930s-1950s. His Neurosurgical Department became the main base for her work until his retirement in 1953. She was an active member of the Medical Artist Association (MAA) which she helped found in 1949.

2015-01-01

This study was designed to provide typical descriptive statistics, score distributions and percentile ranks of the Jefferson Scale of Empathy-Medical Student version (JSE-S) of male and female medical school matriculants to serve as proxy norm data and tentative cutoff scores. The participants were 2,637 students (1,336 women and 1,301 men) who matriculated at Sidney Kimmel (formerly Jefferson) Medical College between 2002 and 2012, and completed the JSE at the beginning of medical school. Information extracted from descriptive statistics, score distributions and percentile ranks for male and female matriculants were used to develop proxy norm data and tentative cutoff scores. The score distributions of the JSE tended to be moderately skewed and platykurtic. Women obtained a significantly higher mean score (116.2 ± 9.7) than men (112.3 ± 10.8) on the JSE-S (t2,635 = 9.9, p < 0.01). It was suggested that percentile ranks can be used as proxy norm data. The tentative cutoff score to identify low scorers was ≤ 95 for men and ≤ 100 for women. Our findings provide norm data and cutoff scores for admission decisions under certain conditions and for identifying students in need of enhancing their empathy. © 2015 S. Karger AG, Basel.

Military barracks in Ghana have backyard poultry populations but the methods used here involve low biosecurity measures and high risk zoonosis such as avian influenza A viruses or Newcastle disease. We assessed biosecurity measures intended to minimize the risk of influenza virus infection among troops and poultry keepers in military barracks. We educated troops and used a questionnaire to collect information on animal populations and handling practices from 168 individuals within 203 households in military barracks. Cloacal and tracheal samples were taken from 892 healthy domestic and domesticated wild birds, 91 sick birds and 6 water samples for analysis using molecular techniques for the detection of influenza A virus. Of the 1090 participants educated and 168 that responded to a questionnaire, 818 (75%) and 129 (76.8%) respectively have heard of pandemic avian influenza and the risks associated with its infection. Even though no evidence of the presence of avian influenza infection was found in the 985 birds sampled, only 19.5% of responders indicated they disinfect their coops regularly and 28% wash their hands after handling their birds. Vaccination of birds and use of personal protective clothing while handling the birds were low putting the people at risk. Though some efforts have been made to improve biosecurity practices, interventions that help to protect the poultry flock from direct contact have to be practiced. Basic hygiene like washing of hands with soap and running water and regular cleaning of chicken coops are needed to prevent the spread of diseases among birds and between birds and humans.

Grames, Joseph; Higinbotham, Douglas; Montgomery, Hugh

The Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Newport News, Virginia, USA, is one of ten national laboratories under the aegis of the Office of Science of the U.S. Department of Energy (DOE). It is managed and operated by Jefferson Science Associates, LLC. The primary facility at Jefferson Lab is the Continuous Electron Beam Accelerator Facility (CEBAF) as shown in an aerial photograph in Figure 1. Jefferson Lab was created in 1984 as CEBAF and started operations for physics in 1995. The accelerator uses superconducting radio-frequency (srf) techniques to generate high-quality beams of electrons with high-intensity, well-controlled polarization. Themore » technology has enabled ancillary facilities to be created. The CEBAF facility is used by an international user community of more than 1200 physicists for a program of exploration and study of nuclear, hadronic matter, the strong interaction and quantum chromodynamics. Additionally, the exceptional quality of the beams facilitates studies of the fundamental symmetries of nature, which complement those of atomic physics on the one hand and of high-energy particle physics on the other. The facility is in the midst of a project to double the energy of the facility and to enhance and expand its experimental facilities. Studies are also pursued with a Free-Electron Laser produced by an energy-recovering linear accelerator.« less

The effect of educational intervention on family planning knowledge, attitudes, and practices among married women in a military barrack in northern Nigeria.

Army barracks in Nigeria have low contraceptive prevalence rates (CPRs) and many children per family. The aim of this interventional study, involving 963 married women, is to determine the impact of health education on family planning knowledge, attitudes, and practices among married barrack women. The intervention group attended a 50-minute health talk and demonstrations on family planning methods. In the intervention group, the mean knowledge score rose significantly, from 5.5 points to 7.8 points post-intervention (t = -16.7281, p = 0.0000, df = 460). In addition, the CPR increased significantly, from 11.8% at baseline to 22.4% post-intervention (McNemar's chi2 = 125.41, p = 0.0000). Such significant changes were not noted in the control group. We conclude that health education is an effective intervention for improving knowledge about and attitudes towards contraceptives and their use among married women in military barracks in Nigeria. Intense and sustained health education is therefore recommended in addressing the low CPR in Nigeria.

The purpose of this study was to assess the clinical empathy of a cohort of medical students spanning 4 years of undergraduate study and to identify factors associated with empathy. A cross-sectional study to assess the empathy of undergraduate medical students at the University College of Medical Sciences and GTB Hospital in Delhi, India, was conducted using the Jefferson Scale of Empathy-Student Version. Demographic data were obtained using a pre-tested, semi-open-ended questionnaire. Of the 600 students, 418 participated in the survey (69.7%). The mean empathy score was 96.01 (of a maximum of 140), with a standard deviation of 14.56. The empathy scores decreased from the first to the third semester, plateaued at the fifth semester, and rose again in the seventh semester. Empathy was found to be significantly associated with the gender of the participant, with females having higher scores (P<0.001). The age of the participant, place of residence, whose decision it was for the student to enroll in an MBBS (bachelor of medicine and bachelor of surgery) program, and the choice of future specialty were not significantly associated with students' empathy scores. The study found significant gender differences in empathy among the participants. The empathy scores tended to decline initially and then rebound over time. The mean empathy levels found in this study are lower than those reported in most similar studies around the world; therefore, further studies are needed to analyze and address the underlying factors associated with this discrepancy.

Mount Jefferson has erupted repeatedly for hundreds of thousands of years, with its last eruptive episode during the last major glaciation which culminated about 15,000 years ago. Geologic evidence shows that Mount Jefferson is capable of large explosive eruptions. The largest such eruption occurred between 35,000 and 100,000 years ago. If Mount Jefferson erupts again, areas close to the eruptive vent will be severely affected, and even areas tens of kilometers (tens of miles) downstream along river valleys or hundreds of kilometers (hundreds of miles) downwind may be at risk. Numerous small volcanoes occupy the area between Mount Jefferson and Mount Hood to the north, and between Mount Jefferson and the Three Sisters region to the south. These small volcanoes tend not to pose the far-reaching hazards associated with Mount Jefferson, but are nonetheless locally important. A concern at Mount Jefferson, but not at the smaller volcanoes, is the possibility that small-to-moderate sized landslides could occur even during periods of no volcanic activity. Such landslides may transform as they move into lahars (watery flows of rock, mud, and debris) that can inundate areas far downstream. The geographic information system (GIS) volcano hazard data layer used to produce the Mount Jefferson volcano hazard map in USGS Open-File Report 99-24 (Walder and others, 1999) is included in this data set. Both proximal and distal hazard zones were delineated by scientists at the Cascades Volcano Observatory and depict various volcano hazard areas around the mountain.

To determine the sexual behavioral pattern, consequences, and adopted solutions among senior secondary schools students in Ojo military barracks, Lagos. This was a cross-sectional study of 400 senior secondary schools students in Ojo military barracks, Lagos, selected using a multistage sampling technique. Data was collected using pre-tested, self-administered semi-structured questionnaires. Data was analysed using statistical package for social sciences version 17. Tests of statistical significance were carried out using χ2-test, and a p-value of <0.05 was considered significant. The majority of them 391 (97.8%), were in the age group (10-19 years) while the mean age was 15±2.4 for males and 15±2.2 for females, respectively. One hundred and fifty four (38.5%) of the respondents have had penetrative sexual intercourse and were influenced mainly by peer pressure (p=0.0000). Their age at first sexual intercourse ranged between 10-19 years. Ten (6.5%) of the respondents (all males) had their sexual debut with a commercial sex worker. More girls 41 (56.2%) than boys 12 (14.8%), were forced into sexual intercourse (p=0.0000). Over half of the sexually active respondents had at least two sexual partners for either sex. Findings from this study have shown that young people living in the barracks indulged in sexual activity at very early ages and engaged in risky sexual behavior. We therefore recommend an improved multi-sectoral approach in reproductive health and sexually transmitted infections including HIV/AIDS education.

FOREWORD: Jefferson Lab: A Long Decade of Physics

2011-04-01

Jefferson Lab Jefferson Lab was created in 1984 and started operating in about 1996. 2011 is an appropriate time to try to take a look at the results that have appeared, what has been learned, and what has been exciting for our scientific community. Rather than attempt to construct a coherent view with a single author or at least a small number, we have, instead, invited small groups of people who have been intimately involved in the work itself to make contributions. These people are accelerator experts, experimentalists and theorists, staff and users. We have, in the main, sought reviews of the actual sub-fields. The primary exception is the first paper, which sets the scene as it was, in one person's view, at the beginning of Jefferson Lab. In reviewing the material as it appeared, I was impressed by the breadth of the material. Major advances are documented from form factors to structure functions, from spectroscopy to physics beyond the standard model of nuclear and particle physics. Recognition of the part played by spin, the helicities of the beams, the polarizations of the targets, and the polarizations of final state particles, is inescapable. Access to the weak interaction amplitudes through measurements of the parity violating asymmetries has led to quantification of the strange content of the nucleon and the neutron radius of lead, and to measurements of the electroweak mixing angle. Lattice QCD calculations flourished and are setting the platform for understanding of the spectroscopy of baryons and mesons. But the star of the game was the accelerator. Its performance enabled the physics and also the use of the technology to generate a powerful free electron laser. These important pieces of Jefferson Lab physics are given their place. As the third Director of Jefferson Lab, and on behalf of the other physicists and others presently associated with the lab, I would like to express my admiration and gratitude for the efforts of the directors, chief

2010-06-01

The Medical College Admission Test (MCAT) has undergone several revisions for content and validity since its inception. With another comprehensive review pending, this study examines changes in the predictive validity of the MCAT's three recent versions. Study participants were 7,859 matriculants in 36 classes entering Jefferson Medical College between 1970 and 2005; 1,728 took the pre-1978 version of the MCAT; 3,032 took the 1978-1991 version, and 3,099 took the post-1991 version. MCAT subtest scores were the predictors, and performance in medical school, attrition, scores on the medical licensing examinations, and ratings of clinical competence in the first year of residency were the criterion measures. No significant improvement in validity coefficients was observed for performance in medical school or residency. Validity coefficients for all three versions of the MCAT in predicting Part I/Step 1 remained stable (in the mid-0.40s, P < .01). A systematic decline was observed in the validity coefficients of the MCAT versions in predicting Part II/Step 2. It started at 0.47 for the pre-1978 version, decreased to between 0.42 and 0.40 for the 1978-1991 versions, and to 0.37 for the post-1991 version. Validity coefficients for the MCAT versions in predicting Part III/Step 3 remained near 0.30. These were generally larger for women than men. Although the findings support the short- and long-term predictive validity of the MCAT, opportunities to strengthen it remain. Subsequent revisions should increase the test's ability to predict performance on United States Medical Licensing Examination Step 2 and must minimize the differential validity for gender.

Empathy is a key cognitive attribute among healthcare professionals that fosters better patient- healthcare provider relationships. The Jefferson scale of empathy (JSE) measures self-rated empathy among various groups of healthcare professionals-health professionals, medical students and health professions students (HPS). The authors present the experience in translating the JSE-HPS version into an Indian regional language with insights into the issues faced in every step. With official permission from the Thomas Jefferson University, the authors embarked on the translation proceeding through forward translation (three rounds of modification), back translation (two independent translates), and synthesis of a final translated version. While targeting literary accuracy, the simplicity and comprehensibility of the instrument by the study population were also ensured. Variations in regional dialects and accents across the population were considered. The back-translated version was evaluated for semantic, content, cultural, and technical equivalence. It was then pretested on ten students followed by a group discussion with them to ensure the comprehensibility of the tool and the differences between written and spoken language were addressed through necessary modifications. The Tamil translation of the HPS version of JSE is now approved by and officially available with the Thomas Jefferson University.

Revitalization is a complex program to restore the functioning of the neglected urban areas in terms of spatial, economic and social. Revitalization activities on post-military facilities are stopping negative phenomena, such as degradation of space, social pathology or lack of proper functioning of the area, adapted to modern needs. The object of the work is to present some aspects with the revitalization of former military facilities in the area of the Artyleryjska Street in Olsztyn. The presented design concept aims to revitalize a neglected area of the barracks, which will enable the activation site and include it in the city urban space. The method adopted in this work is the architectural project of adapting selected post-military facilities for new functions, affecting the economic development and social integration of people.

DC high voltage photoemission electron guns with GaAs photocathodes have been used to produce polarized electron beams for nuclear physics experiments for about 3 decades with great success. In the late 1990s, Jefferson Lab adopted this gun technology for a free electron laser (FEL), but to assist with high bunch charge operation, considerably higher bias voltage is required compared to the photoguns used at the Jefferson Lab Continuous Electron Beam Accelerator Facility. The FEL gun has been conditioned above 400 kV several times, albeit encountering non-trivial challenges with ceramic insulators and field emission from electrodes. Recently, high voltage processing withmore » krypton gas was employed to process very stubborn field emitters.

Mineral and reconnaissance geothermal surveys of the Mount Jefferson Primitive Area in the Cascade Range of Oregon indicate little likelihood that metallic or nonmetallic mineral or energy resources exist in the area. Several mining claims, presumably located for gold, are present, but analyses of samples from the claims failed to detect the presence of gold or other valuable metals. Rock for construction purposes is abundantly present, but better and more accessible deposits are available in adjacent areas.

Abraham Lincoln's suit against a medical imposter who assaulted his client.

PubMed

Spiegel, A D; Kavaler, F

2001-10-01

In 1851, A. Lincoln, Esquire represented Edward Jones who charged in a law suit that his attending physician had assaulted him. Jones, also a lawyer, had sharply questioned Dr. Joseph S. Maus about his claims of attendance and graduation from Philadelphia's Jefferson Medical College, an allopathic medical school. Jones claimed that Maus became enraged at his persistent questioning and attacked him. In turn, Maus denied the allegation. He said that he was merely defending himself from Jones' blows with a large cane. Lincoln's legal approach was to argue about the state of medical education and whether Maus had really graduated from Jefferson Medical College. Acting as a peacemaker, he finally arranged to settle the dispute between Jones and Maus out of court.

Yan, Jianxun; Seaton, Chad; Allison, Trent L.

A new EPICS/RTEMS IOC based on the Altera System-on-Chip (SoC) FPGA is being designed at Jefferson Lab. The Altera SoC FPGA integrates a dual ARM Cortex-A9 Hard Processor System (HPS) consisting of processor, peripherals and memory interfaces tied seamlessly with the FPGA fabric using a high-bandwidth interconnect backbone. The embedded Altera SoC IOC has features of remote network boot via U-Boot from SD card or QSPI Flash, 1Gig Ethernet, 1GB DDR3 SDRAM on HPS, UART serial ports, and ISA bus interface. RTEMS for the ARM processor BSP were built with CEXP shell, which will dynamically load the EPICS applications atmore » runtime. U-Boot is the primary bootloader to remotely load the kernel image into local memory from a DHCP/TFTP server over Ethernet, and automatically run RTEMS and EPICS. The first design of the SoC IOC will be compatible with Jefferson Lab’s current PC104 IOCs, which have been running in CEBAF 10 years. The next design would be mounting in a chassis and connected to a daughter card via standard HSMC connectors. This standard SoC IOC will become the next generation of low-level IOC for the accelerator controls at Jefferson Lab.« less

Ornamental Planting Restoration at Jefferson's Poplar Forest Through XRF and ICP-OES Analysis of Disturbed Soils

NASA Astrophysics Data System (ADS)

Hatfield, M.; Low, P. C.; Devlin, S.

2011-12-01

Thomas Jefferson's Poplar Forest estate near Lynchburg, VA is currently attempting to restore the property to its Jeffersonian condition. Subsequent modifications to the property following its sale by Jefferson's heirs included the removal of the original trees in order to facilitate agricultural activity. One key facet of the restoration involves determining the precise location of the sixty-four paper mulberry trees that Jefferson reportedly had transplanted in 1815 from his on-site nursery to near the main house. At Monticello, it is well-documented that Jefferson used contextually innovative fertilizing techniques, including the addition of gypsum and lime "to restore the exhaustion of a single crop from the soil." Whether he used these methods in the nursery at Poplar Forest to the degree that decades of subsequent leaching, weathering, and other disturbances would not erase remains historically and analytically unclear. Since the transplantation process requires that large amounts of soil be moved with the trees, small areas of compositionally distinct soils in the suspected planting area could be used to establish the exact location of each tree through differentiating between nursery and in situ soils. Through X-ray fluorescence spectroscopy (XRF) and intercoupled plasma optical emission spectroscopy (ICP-OES) geochemical analysis, the specific composition of soil can be determined. Preliminary analysis shows slight differences in phosphorus and sulfur between the nursery and in situ soil; however, the property lies on three different distinct geological units: actinolite schist and feldspathic metagreywacke units of the Alligator Back formation, and biotite gneiss of the Ashe Formation (biotite gneiss). The location of the nursery where the sixty-four paper mulberry trees were originally grown lies on the feldspathic metagreywacke unit; whereas the relocation site where Jefferson had them planted rests on the actinolite schist unit.

2017-01-01

Controversy exists regarding the management of unstable Jefferson fractures, with some surgeons performing reduction and immobilization of the patient in a halo vest and others performing open reduction and internal fixation. This study compares the clinical and radiological outcome parameters between posterior atlantoaxial fusion (AAF) and occipitocervical fusion (OCF) constructs in the treatment of the unstable atlas fracture. 68 consecutive patients with unstable Jefferson fractures treated by AAF or OCF between October 2004 and March 2011 were included in this retrospective evaluation from institutional databases. The authors reviewed medical records and original images. The patients were divided into two surgical groups treated with either AAF ( n = 48, F/M 30:18) and OCF ( n = 20, F/M 13:7) fusion. Blood loss, operative time, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, atlanto-dens interval, lateral mass displacement, complications, and the bone fusion rates were recorded. Five patients with incomplete paralysis (7.4%) demonstrated postoperative improvement by more than 1 grade on the American Spinal Injury Association impairment scale. The JOA score of the AAF group improved from 12.5 ± 3.6 preoperatively to 15.7 ± 2.3 postoperatively, while the JOA score of the OCF group improved from 11.2 ± 3.3 preoperatively to 14.8 ± 4.2 postoperatively. The VAS score of AAF group decreased from 4.8 ± 1.5 preoperatively to 1.0 ± 0.4 postoperatively, the VAS score of the OCF group decreased from 5.4 ± 2.2 preoperatively to 1.3 ± 0.9 postoperatively. The OCF or AAF combined with short-term external immobilization can establish the upper cervical stability and prevent further spinal cord injury and nerve function damage.

Precision Electron Beam Polarimetry in Hall C at Jefferson Lab

NASA Astrophysics Data System (ADS)

Gaskell, David

2013-10-01

The electron beam polarization in experimental Hall C at Jefferson Lab is measured using two devices. The Hall-C/Basel Møller polarimeter measures the beam polarization via electron-electron scattering and utilizes a novel target system in which a pure iron foil is driven to magnetic saturation (out of plane) using a superconducting solenoid. A Compton polarimeter measures the polarization via electron-photon scattering, where the photons are provided by a high-power, CW laser coupled to a low gain Fabry-Perot cavity. In this case, both the Compton-scattered electrons and backscattered photons provide measurements of the beam polarization. Results from both polarimeters, acquired during the Q-Weak experiment in Hall C, will be presented. In particular, the results of a test in which the Møller and Compton polarimeters made interleaving measurements at identical beam currents will be shown. In addition, plans for operation of both devices after completion of the Jefferson Lab 12 GeV Upgrade will also be discussed.

Quark Hadron Duality - Recent Jefferson Lab Results

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

Niculescu, Maria Ioana

2016-08-01

The duality between the partonic and hadronic descriptions of electron--nucleon scattering is a remarkable feature of nuclear interactions. When averaged over appropriate energy intervals the cross section at low energy which is dominated by nucleon resonances resembles the smooth behavior expected from perturbative QCD. Recent Jefferson Lab results indicate that quark-hadron duality is present in a variety of observables, not just the proton F2 structure function. An overview of recent results, especially local quark-hadron duality on the neutron, are presented here.

Medical educators agree that empathy is essential for physicians' professionalism. The Health Professional Version of the Jefferson Scale of Empathy (JSE-HP) was developed in response to a need for a psychometrically sound instrument to measure empathy in the context of patient care. Although extensive support for its validity and reliability is available, the authors recognize the necessity to examine psychometrics of the JSE-HP in different socio-cultural contexts to assure the psychometric soundness of this instrument. The first aim of this study was to confirm its psychometric properties in the cross-cultural context of Spain and Latin American countries. The second aim was to measure the influence of social and cultural factors on the development of medical empathy in health practitioners. The original English version of the JSE-HP was translated into International Spanish using back-translation procedures. The Spanish version of the JSE-HP was administered to 896 physicians from Spain and 13 Latin American countries. Data were subjected to exploratory factor analysis using principal component analysis (PCA) with oblique rotation (promax) to allow for correlation among the resulting factors, followed by a second analysis, using confirmatory factor analysis (CFA). Two theoretical models, one based on the English JSE-HP and another on the first Spanish student version of the JSE (JSE-S), were tested. Demographic variables were compared using group comparisons. A total of 715 (80%) surveys were returned fully completed. Cronbach's alpha coefficient of the JSE for the entire sample was 0.84. The psychometric properties of the Spanish JSE-HP matched those of the original English JSE-HP. However, the Spanish JSE-S model proved more appropriate than the original English model for the sample in this study. Group comparisons among physicians classified by gender, medical specialties, cultural and cross-cultural backgrounds yielded statistically significant differences

Kebede, Ellene; Schreiner, Dean F; Huluka, Gobena

2002-05-01

This paper uses an integrated economic-environmental model to assess the point source pollution from major industries in Jefferson County, Northern Alabama. Industrial expansion generates employment, income, and tax revenue for the public sector; however, it is also often associated with the discharge of chemical pollutants. Jefferson County is one of the largest industrial counties in Alabama that experienced smog warnings and ambient ozone concentration, 1996-1999. Past studies of chemical discharge from industries have used models to assess the pollution impact of individual plants. This study, however, uses an extended Input-Output (I-O) economic model with pollution emission coefficients to assess direct and indirect pollutant emission for several major industries in Jefferson County. The major findings of the study are: (a) the principal emission by the selected industries are volatile organic compounds (VOC) and these contribute to the ambient ozone concentration; (b) the direct and indirect emissions are significantly higher than the direct emission by some industries, indicating that an isolated analysis will underestimate the emission by an industry; (c) while low emission coefficient industries may suggest industry choice they may also emit the most hazardous chemicals. This study is limited by the assumptions made, and the data availability, however it provides a useful analytical tool for direct and cumulative emission estimation and generates insights on the complexity in choice of industries.

Hojat, Mohammadreza; Vergare, Michael; Isenberg, Gerald; Cohen, Mitchell; Spandorfer, John

2015-01-29

This study was designed to explore the underlying construct of measures of empathy, optimism, and burnout in medical students. Three instruments for measuring empathy (Jefferson Scale of Empathy, JSE); Optimism (the Life Orientation Test-Revised, LOT-R); and burnout (the Maslach Burnout Inventory, MBI, which includes three scales of Emotional Exhaustion, Depersonalization, and Personal Accomplishment) were administered to 265 third-year students at Sidney Kimmel (formerly Jefferson) Medical College at Thomas Jefferson University. Data were subjected to factor analysis to examine relationships among measures of empathy, optimism, and burnout in a multivariate statistical model. Factor analysis (principal component with oblique rotation) resulted in two underlying constructs, each with an eigenvalue greater than one. The first factor involved "positive personality attributes" (factor coefficients greater than .58 for measures of empathy, optimism, and personal accomplishment). The second factor involved "negative personality attributes" (factor coefficients greater than .78 for measures of emotional exhaustion, and depersonalization). Results confirmed that an association exists between empathy in the context of patient care and personality characteristics that are conducive to relationship building, and considered to be "positive personality attributes," as opposed to personality characteristics that are considered as "negative personality attributes" that are detrimental to interpersonal relationships. Implications for the professional development of physicians-in-training and in-practice are discussed.

EMC effect for light nuclei: New results from Jefferson Lab

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

Aji Daniel

High energy lepton scattering has been the primary tool for mapping out the quark distributions of nucleons and nuclei. Measurements of deep inelastic scattering in nuclei show that the quark distributions in heavy nuclei are not simply the sum of the quark distributions of the constituent proton and neutron, as one might expect for a weakly bound system. This modification of the quark distributions in nuclei is known as the EMC effect. I will discuss the results from Jefferson Lab (JLab) experiment E03-103, a precise measurement of the EMC effect in few-body nuclei with emphasis on the large x region.more » Data from the light nuclei suggests that the nuclear dependence of the high x quark distribution may depend on the nucleon's local environment, rather than being a purely bulk effect. In addition, I will also discuss about a future experiment at the upgraded 12 GeV Jefferson Lab facility which will further investigate the role of the local nuclear environment and the influence of detailed nuclear structure to the modification of quark distributions.« less

Jefferson Lab have made significant contributions to improve our knowledge of the longitudinal spin structure by measuring polarized structure functions, g1 and g2, down to Q2 = 0.02 GeV2. The low Q2 data is especially useful in testing the Chiral Perturbation theory (cPT) calculations. The spin-dependent sum rules and the spin polarizabilities, constructed from the moments of g1 and g2, provide an important tool to study the longitudinal spin structure. We will present an overview of the experimental program to measure these structure functions at Jefferson Lab, and present some recent results on the neutron polarizabilities, proton g1 at lowmore » Q2, and proton and neutron d2 measurement. In addition to this, we will discuss the transverse spin structure of the nucleon which can be accessed using chiral-odd transversity distribution (h1), and show some results from measurements done on polarized 3He target in Hall A.« less

Trends along the debt-income axis: implications for medical students' selections of family practice careers.

PubMed

Rosenthal, M P; Marquette, P A; Diamond, J J

1996-06-01

To examine whether medical students' levels of debt have an influence on selection of family practice careers, independent of other factors. Data from the Jefferson Longitudinal Study were analyzed for 1,350 graduates from the classes of 1987-1993 at Jefferson Medical College of Thomas Jefferson University; a focused analysis for 326 graduates from the classes of 1992 and 1993 was specifically performed to identify recent trends. A binary logistic regression equation was used to predict the probability of a graduate's entrance into a family practice residency based on first-year preference for family practice, income expectation, debt level, age, and gender. A high level of indebtedness (at least $75,000) was a significant independent predictor of specialty choice (away from family practice); first-year preference for family practice and income expectation were also significant independent predictors. Combining these three factors (debt, specialty preference, and income expectation) led to a greater than 12-fold difference in specialty selection of family practice. Notably, 36% of the students graduating in 1992-1993 had debts of at least $75,000, more than three times the percentage in the classes graduating in 1987-1989. High levels of debt had a significant negative effect on family practice specialty, choice among recent Jefferson graduates. An increase in the number of students with such debt carries strong implications for the selection of careers in family practice.

A psychometric appraisal of the Jefferson Scale of Empathy using law students.

A growing body of literature indicates that empathic behaviors are positively linked, in several ways, with the professional performance and mental well-being of lawyers and law students. It is therefore important to assess empathy levels among law students using psychometrically sound tools that are suitable for this cohort. The 20-item Jefferson Scale of Empathy - Health Profession Students Version was adapted for a law context (eg, the word "health care" became "legal"), and the new Jefferson Scale of Empathy - Law Students (JSE-L-S) version was completed by 275 students at Monash University, Melbourne, Australia. Data were subjected to principal component analysis. Four factors emerged from the principal component analysis ("understanding the client's perspective", "responding to clients' experiences and emotions", "responding to clients' cues and behaviors", and "standing in clients' shoes"), which accounted for 46.7% of the total variance. The reliability of the factors varied, but the overall 18-item JSE-L-S yielded a Cronbach's alpha coefficient of 0.80. Several patterns among the item loadings were similar to those reported in studies using other versions of the Jefferson Scale of Empathy. The JSE-L-S appears to be a reliable measure of empathy among undergraduate law students, which could help provide insights into law student welfare and future performance as legal practitioners. Additional evaluation of the JSE-L-S is required to disambiguate some of the minor findings explored. Adjustments may improve the psychometric properties.

Jefferson Lab Experimental Hall C

NASA Astrophysics Data System (ADS)

Carlini, Roger D.

1996-10-01

Jefferson Lab's Hall C went into initial operation in November 1995. The hall has a short orbit spectrometer (SOS) for short-lived particles such as pions and kaons and a high-momentum spectrometer (HMS) usually used for electrons. The SOS can also be used for protons. The HMS can range to 7 GeV/c. Both the SOS and HMS have typical resolutions of (10-3). Experiments for this hall range from measuring the neutron electric form factor, to color transparency, to creating strange nuclei. This paper will present the optical capabilities of the spectrometers, the parameters of the detection systems, and the overall beam line characteristics of the hall as determined from the results from the recent physics experiments along with the upcoming experimental schedule.

2017-07-01

We explored differences in changes in medical student empathy in the third year of medical school between volunteers at JeffHOPE, a multisite medical student-run free clinic of Sidney Kimmel Medical College (SKMC), and nonvolunteers. Volunteerism and leadership experience at JeffHOPE were documented for medical students in the Class of 2015 (n = 272) across their medical educations. Students completed the Jefferson Scale of Empathy at the beginning of medical school and at the end of the third year. Students who reported participation in other Jefferson-affiliated clinics (n = 44) were excluded from this study. Complete data were available for 188 SKMC students. Forty-five percent of students (n = 85) volunteered at JeffHOPE at least once during their medical educations. Fifteen percent of students (n = 48) were selected for leadership positions involving weekly clinic participation. Nonvolunteers demonstrated significant decline in empathy in medical school ( P = 0.009), while those who volunteered at JeffHOPE at least once over the course of their medical educations did not show any significant decline ( P = 0.07). These findings suggest that medical students may benefit from volunteering at student-run free clinics to care for underserved populations throughout medical school.

5 MeV Mott Polarimeter Development at Jefferson Lab

Price, J. S.; Sinclair, C. K.; Cardman, L. S.

1997-01-01

Low energy (E{sub k}=100 keV) Mott scattering polarimeters are ill- suited to support operations foreseen for the polarized electron injector at Jefferson Lab. One solution is to measure the polarization at 5 MeV where multiple and plural scattering are unimportant and precision beam monitoring is straightforward. The higher injector beam current offsets the lower cross-sections. Recent improvements in the CEBAF injector polarimeter scattering chamber have improved signal to noise.

Williams, Brett; Sifris, Adiva; Lynch, Marty

2016-01-01

Background A growing body of literature indicates that empathic behaviors are positively linked, in several ways, with the professional performance and mental well-being of lawyers and law students. It is therefore important to assess empathy levels among law students using psychometrically sound tools that are suitable for this cohort. Participants and methods The 20-item Jefferson Scale of Empathy – Health Profession Students Version was adapted for a law context (eg, the word “health care” became “legal”), and the new Jefferson Scale of Empathy – Law Students (JSE-L-S) version was completed by 275 students at Monash University, Melbourne, Australia. Data were subjected to principal component analysis. Results Four factors emerged from the principal component analysis (“understanding the client’s perspective”, “responding to clients’ experiences and emotions”, “responding to clients’ cues and behaviors”, and “standing in clients’ shoes”), which accounted for 46.7% of the total variance. The reliability of the factors varied, but the overall 18-item JSE-L-S yielded a Cronbach’s alpha coefficient of 0.80. Several patterns among the item loadings were similar to those reported in studies using other versions of the Jefferson Scale of Empathy. Conclusion The JSE-L-S appears to be a reliable measure of empathy among undergraduate law students, which could help provide insights into law student welfare and future performance as legal practitioners. Additional evaluation of the JSE-L-S is required to disambiguate some of the minor findings explored. Adjustments may improve the psychometric properties. PMID:27524924

Youssef, Farid F.; Nunes, Paula; Sa, Bidyadhar; Williams, Stella

2014-01-01

Objectives: This study explored the empathy profile of students across five years of medical training. In addition the study examined whether the Jefferson Scale for Physician Empathy correlated with a measure of cognitive empathy, the Reading the Mind in the Eyes Test and a measure of affective empathy, the Toronto Empathy Questionnaire. Methods: The study was a comparative cross-sectional design at one Caribbean medical school. Students were contacted in class, participation was voluntary and empathy was assessed using all three instruments Descriptive statistics were calculated and differences between groups evaluated using non-parametric tests. Results: Overall 669 students participated (response rate, 67%). There was a significant correlation between the Jefferson Scale of Physician Empathy and the Toronto Empathy Questionnaire (P = 0.48), both scales indicating a decline in medical student empathy scores over time. There was, however, little correlation between scores from the Reading the Mind in the Eyes Test and the Jefferson Scale of Physician Empathy. Female students demonstrated significantly higher scores on all three measures. Conclusions: Medical students’ lower empathy scores during their final years of training appear to be due to a change in the affective component of empathy. These findings may reflect an adaptive neurobiological response to the stressors associated with encountering new clinical situations. Attention should be paid not only to providing empathy training for students but also to teaching strategies for improved cognitive processing capacity when they are encountering new and challenging circumstances.

2015-01-01

Objectives This study was designed to explore the underlying construct of measures of empathy, optimism, and burnout in medical students. Methods Three instruments for measuring empathy (Jefferson Scale of Empathy, JSE); Optimism (the Life Orientation Test-Revised, LOT-R); and burnout (the Maslach Burnout Inventory, MBI, which includes three scales of Emotional Exhaustion, Depersonalization, and Personal Accomplishment) were administered to 265 third-year students at Sidney Kimmel (formerly Jefferson) Medical College at Thomas Jefferson University. Data were subjected to factor analysis to examine relationships among measures of empathy, optimism, and burnout in a multivariate statistical model.  Results Factor analysis (principal component with oblique rotation) resulted in two underlying constructs, each with an eigenvalue greater than one. The first factor involved “positive personality attributes” (factor coefficients greater than .58 for measures of empathy, optimism, and personal accomplishment). The second factor involved “negative personality attributes” (factor coefficients greater than .78 for measures of emotional exhaustion, and depersonalization). Conclusions Results confirmed that an  association exists between empathy in the context of patient care and personality characteristics that are conducive to relationship building, and considered to be  “positive personality attributes,” as opposed to personality characteristics that are considered as “negative personality attributes” that are detrimental to interpersonal relationships. Implications for the professional development of physicians-in-training and in-practice are discussed. PMID:25633650

Qiang, Yi

2015-05-01

Jefferson Lab will soon finish its highly anticipated 12 GeV Upgrade. With doubled maximum energy, Jefferson Lab’s Continuous Electron Beam Accelerator Facility (CEBAF) will enable a new experimental program with substantial discovery potential, addressing important topics in nuclear, hadronic and electroweak physics. In order to take full advantage of the high energy, high luminosity beam, new detectors are being developed, designed and constructed to fit the needs of different physics topics. The paper will give an overview of various new detector technologies to be used for 12 GeV experiments. It will then focus on the development of two solenoid-based spectrometers,more » the GlueX and SoLID spectrometers. The GlueX experiment in Hall D will study the complex properties of gluons through exotic hybrid meson spectroscopy. The GlueX spectrometer, a hermetic detector package designed for spectroscopy and the associated partial wave analysis, is currently in the final stage of construction. Hall A, on the other hand, is developing the SoLID spectrometer to capture the 3D image of the nucleon from semi-inclusive processes and to study the intrinsic properties of quarks through mirror symmetry breaking. Such a spectrometer will have the capability to handle very high event rates while still maintaining a large acceptance in the forward region.« less

Moore, B.L.; Evaldi, R.D.

1995-01-01

Bottom sediments from 25 stream sites in Jefferson County, Ky., were analyzed for percent volatile solids and concentrations of nutrients, major metals, trace elements, miscellaneous inorganic compounds, and selected organic compounds. Statistical high outliers of the constituent concentrations analyzed for in the bottom sediments were defined as a measure of possible elevated concentrations. Statistical high outliers were determined for at least 1 constituent at each of 12 sampling sites in Jefferson County. Of the 10 stream basins sampled in Jefferson County, the Middle Fork Beargrass Basin, Cedar Creek Basin, and Harrods Creek Basin were the only three basins where a statistical high outlier was not found for any of the measured constituents. In the Pennsylvania Run Basin, total volatile solids, nitrate plus nitrite, and endrin constituents were statistical high outliers. Pond Creek was the only basin where five constituents were statistical high outliers-barium, beryllium, cadmium, chromium, and silver. Nitrate plus nitrite and copper constituents were the only statistical high outliers found in the Mill Creek Basin. In the Floyds Fork Basin, nitrate plus nitrite, phosphorus, mercury, and silver constituents were the only statistical high outliers. Ammonia was the only statistical high outlier found in the South Fork Beargrass Basin. In the Goose Creek Basin, mercury and silver constituents were the only statistical high outliers. Cyanide was the only statistical high outlier in the Muddy Fork Basin.

Petabyte Class Storage at Jefferson Lab (CEBAF)

NASA Technical Reports Server (NTRS)

Chambers, Rita; Davis, Mark

1996-01-01

By 1997, the Thomas Jefferson National Accelerator Facility will collect over one Terabyte of raw information per day of Accelerator operation from three concurrently operating Experimental Halls. When post-processing is included, roughly 250 TB of raw and formatted experimental data will be generated each year. By the year 2000, a total of one Petabyte will be stored on-line. Critical to the experimental program at Jefferson Lab (JLab) is the networking and computational capability to collect, store, retrieve, and reconstruct data on this scale. The design criteria include support of a raw data stream of 10-12 MB/second from Experimental Hall B, which will operate the CEBAF (Continuous Electron Beam Accelerator Facility) Large Acceptance Spectrometer (CLAS). Keeping up with this data stream implies design strategies that provide storage guarantees during accelerator operation, minimize the number of times data is buffered allow seamless access to specific data sets for the researcher, synchronize data retrievals with the scheduling of postprocessing calculations on the data reconstruction CPU farms, as well as support the site capability to perform data reconstruction and reduction at the same overall rate at which new data is being collected. The current implementation employs state-of-the-art StorageTek Redwood tape drives and robotics library integrated with the Open Storage Manager (OSM) Hierarchical Storage Management software (Computer Associates, International), the use of Fibre Channel RAID disks dual-ported between Sun Microsystems SMP servers, and a network-based interface to a 10,000 SPECint92 data processing CPU farm. Issues of efficiency, scalability, and manageability will become critical to meet the year 2000 requirements for a Petabyte of near-line storage interfaced to over 30,000 SPECint92 of data processing power.

Short Distance of Nuclei - Mining the Wealth of Existing Jefferson Lab Data - Final Report

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

Weinstein, Lawrence; Kuhn, Sebastian

Over the last fifteen years of operation, the Jefferson Lab CLAS Collaboration has performed many experiments using nuclear targets. Because the CLAS detector has a very large acceptance and because it used a very open (i.e., nonspecific) trigger, there is a vast amount of data on many different reaction channels yet to be analyzed. The goal of the Jefferson Lab Nuclear Data Mining grant was to (1) collect the data from nuclear target experiments using the CLAS detector, (2) collect the associated cuts and corrections used to analyze that data, (3) provide non-expert users with a software environment for easymore » analysis of the data, and (4) to search for interesting reaction signatures in the data. We formed the Jefferson Lab Nuclear Data Mining collaboration under the auspices of this grant. The collaboration successfully carried out all of our goals. Dr. Gavalian, the data mining scientist, created a remarkably user-friendly web-based interface to enable easy analysis of the nuclear-target data by non-experts. Data from many of the CLAS nuclear target experiments has been made available on servers at Old Dominion University. Many of the associated cuts and corrections have been incorporated into the data mining software. The data mining collaboration was extraordinarily successful in finding interesting reaction signatures in the data. Our paper Momentum sharing in imbalanced Fermi systems was published in Science. Several analyses of CLAS data are continuing and will result in papers after the end of the grant period. We have held several analysis workshops and have given many invited talks at international conferences and workshops related to the data mining initiative. Our initiative to maximize the impact of data collected with CLAS in the 6-GeV era was very successful. During the hiatus between the end of 6-GeV experiments and the beginning of 12-GeV experiments, our collaboration and the physics community at large benefited tremendously from the

To examine whether an intervention on proper use of electronic medical records (EMRs) in patient care could help improve medical students' empathic engagement, and to test the hypothesis that the training would reduce communication hurdles in clinical encounters. Seventy third-year medical students from the Sidney Kimmel Medical College at Thomas Jefferson University were randomly divided into intervention and control groups during their six-week pediatric clerkship in 2012-2013. The intervention group received a one-hour training session on EMR-specific communication skills, including discussion of EMR use, the SALTED mnemonic and technique (Set-up, Ask, Listen, Type, Exceptions, Documentation), and role-plays. Both groups completed the Jefferson Scale of Empathy (JSE) at the clerkship's start and end. At clerkship's end, faculty and standardized patients (SPs) rated students' empathic engagement in SP encounters, using the Jefferson Scale of Patient Perceptions of Physician Empathy (JSPPPE), and their history-taking and communication skills. Faculty mean ratings on the JSPPPE, history-taking skills, and communication skills were significantly higher for the intervention group than the control group. SP mean ratings on history-taking skills were significantly higher for the intervention group than the control group. Both groups' JSE mean scores increased pretest to posttest, but the changes were not significant. The intervention group's posttest JSE mean score was higher than the control group's, but the difference was not significant. The findings suggest that a simple intervention providing specialized training in EMR-specific communication can improve medical students' empathic engagement in patient care, history-taking skills, and communication skills.

Proposal for a slow positron facility at Jefferson National Laboratory

Mills, Allen P.

2018-05-01

One goal of the JPos-17 International Workshop on Physics with Positrons was to ascertain whether it would be a good idea to expand the mission of the Thomas Jefferson National Accelerator Facility (JLab) to include science with low energy (i.e. "slow") spin polarized positrons. It is probably true that experimentation with slow positrons would potentially have wide-ranging benefits comparable to those obtained with neutron and x-ray scattering, but it is certain that the full range of these benefits will never be fully available without an infrastructure comparable to that of existing neutron and x-ray facilities. The role for Jefferson Laboratory would therefore be to provide and maintain (1) a dedicated set of machines for making and manipulating high intensity, high brightness beams of polarized slow positrons; (2) a suite of unique and easily used instruments of wide utility that will make efficient use of the positrons; and (3) a group of on-site positron scientists to provide scientific leadership, instrument development, and user support. In this note some examples will be given of the science that might make a serious investment in a positron facility worthwhile. At the same time, the lessons learned from various proposed and successful positron facilities will be presented for consideration.

Results From the N* Program at Jefferson Lab

2011-06-01

We discuss the results on the fundamental degrees of freedom underlying the nucleon excitation spectrum and how they evolve as the resonance transitions are investigated with increasingly better space-time resolution of the electromagnetic probe. Improved photocouplings for a number of resonant states, those for the N(1720)P13 being significantly changed, have been determined and entered into the 2008 edition of the RPP. Strong sensitivity to the N(1900)P13 state, listed now as a 2-star state in the same edition of RPP, has been observed in KΛ and KΣ photoproduction. None of the earlier observations of a Θ+5(1540) was confirmed in a seriesmore » of three Jefferson Lab high statistics dedicated measurements, and stringent upper limits on production cross sections were placed in several channels. For the four lowest excited states, the Δ(1232)P33, N(1440)P11, N(1520)D13, and N(1535)S11, the transition amplitudes have been measured in a wide range in photon virtuality Q2. The amplitudes for the Δ(1232) show the importance of the pion-cloud contribution and do not show any sign of approaching the pQCD regime for Q2 < 7 GeV2. For the Roper resonance, N(1440)P11, the data provide strong evidence for this state as a predominantly radial excitation of the nucleon as a 3-quark ground state. For the N(1535)S11, comparison of the results extracted from π and η photo- and electroproduction data allowed one to specify the branching ratios of this state to the πN and ηN channels; they entered into the 2010 edition of the RPP. Measured for the first time, the longitudinal transition amplitude for the N(1535)S11 became a challenge for quark models and can be indicative of large meson-cloud contributions or alternative representations of this state. The N(1520)D13 clearly shows the rapid changeover from helicity-3/2 dominance at the real photon point to helicity-1/2 dominance at Q2 > 0.5 GeV2 confirming a long-standing prediction of the constituent quark model.

Linear regression models are presented for estimating storm-runoff volumes, and mean con- centrations and loads of selected constituents in storm runoff from urban watersheds of Jefferson County, Kentucky. Constituents modeled include dissolved oxygen, biochemical and chemical oxygen demand, total and suspended solids, volatile residue, nitrogen, phosphorus and phosphate, calcium, magnesium, barium, copper, iron, lead, and zinc. Model estimations are a function of drainage area, percentage of impervious area, climatological data, and land uses. Estimation models are based on runoff volumes, and concen- trations and loads of constituents in runoff measured at 6 stormwater outfalls and 25 streams in Jefferson County.

Jefferson Lab 12 GEV Cebaf Upgrade

The existing continuous electron beam accelerator facility (CEBAF) at Thomas Jefferson National Accelerator Facility (TJNAF) is a 5-pass, recirculating cw electron Linac operating at ˜6 GeV and is devoted to basic research in nuclear physics. The 12 GeV CEBAF Upgrade is a 310 M project, sponsored by the Department of Energy (DOE) Office of Nuclear Physics, that will expand its research capabilities substantially by doubling the maximum energy and adding major new experimental apparatus. The project received construction approval in September 2008 and has started the major procurement process. The cryogenic aspects of the 12 GeV CEBAF Upgrade includes: doubling the accelerating voltages of the Linacs by adding ten new high-performance, superconducting radiofrequency (SRF) cryomodules (CMs) to the existing 42 1/4 cryomodules; doubling of the 2 K cryogenics plant; and the addition of eight superconducting magnets.

Searching for dark photon with positrons at Jefferson lab

NASA Astrophysics Data System (ADS)

Marsicano, Luca

2018-05-01

The interest in the Dark Photon (A' or U) has recently grown, since it could act as a light mediator to a new sector of Dark Matter particles. In this paradigm, the electron-positron annihilation can rarely produce a γA' pair. Various experiments (e.g. PADME@LNF [1], VEPP-3 [2]) have been proposed to detect this process using positron beams impinging on fixed targets. In such experiments, the energy of the photon from the e+e-→ γA' process is measured with an electromagnetic calorimeter and the missing mass is computed (the A' interacts weakly with Standard Model matter so it can't be detected). However, the A' mass range that can be explored with this technique is limited by the accessible energy in the center of mass frame, which goes as the square root of the beam energy. The realization of a 11 GeV positron beam at Jefferson Lab would allow to search for A' masses up to ˜ 100 MeV, reaching unexplored regions of the A' parameter space. A preliminary study on the feasibility of a PADME-like experiment at Jefferson Lab has been carried out, assuming a 11 GeV positron beam with a ˜ 100 nA current. The achievable sensitivity was estimated, studying the main sources of background (positron bremsstrahlung, annihilation into 2 gammas) using CALCHEP [3] and GEANT4 [4] simulations.

Occipital Neuralgia after Occipital Cervical Fusion to Treat an Unstable Jefferson Fracture

PubMed Central

Kong, Seong Ju; Park, Jin Hoon

2012-01-01

In this report we describe a patient with an unstable Jefferson fracture who was treated by occipitocervical fusion and later reported sustained postoperative occipital neuralgia. A 70-year-old male was admitted to our center with a Jefferson fracture induced by a car accident. Preoperative lateral X-ray revealed an atlanto-dens interval of 4.8mm and a C1 canal anterior-posterior diameter of 19.94mm. We performed fusion surgery from the occiput to C5 without decompression of C1. The patient reported sustained continuous pain throughout the following year despite strong analgesics. The pain dermatome was located mainly in the great occipital nerve territory and posterior neck. Magnetic resonance images revealed no evidence of cord compression, however a C1 lamina compressed dural sac and C2 root compression could not be excluded. We performed bilateral C2 root decompression via a C1 laminectomy. After decompression, bilateral C2 root redundancy was identified by palpation. After decompression surgery, pain was reduced. This case indicates that occipital neuralgia, suggesting the need for diagnostic block, should be considered in the differential diagnosis of patients with sustained occipital headache after occipitocervical fusion surgery.

Celentano, Andrea

2015-06-01

The existence of MeV-GeV dark matter (DM) is theoretically well motivated but remarkably unexplored. The Beam Dump eXperiment (BDX) at Jefferson Laboratory aims to investigate this mass range. Dark matter particles will be detected trough scattering on a segmented, plastic scintillator detector placed downstream of the beam-dump at one of the high intensity JLab experimental Halls. The experiment will collect up to 1022 electrons-on-target (EOT) in a one-year period. For these conditions, BDX is sensitive to the DM-nucleon elastic scattering at the level of a thousand counts per year, and is only limited by cosmogenic backgrounds. The experiment is also sensitive to DM-electron elastic and inelastic scattering, at the level of 10 counts/year. The foreseen signal for these channels is an high-energy (> 100 MeV) electromagnetic shower, with almost no background. The experiment, has been presented in form of a Letter of Intent to the laboratory, receiving positive feedback, and is currently being designed.

2000-10-01

A scintillating fiber hodoscope has been built for use as a photon beam profiler in the bremsstrahlung tagged photon beam in Hall B of the Thomas Jefferson National Accelerator Facility (Jefferson Lab). The device consists of a linear array of 64 2-2 mm2 scintillating fibers glued to a corresponding set of light guide fibers. Both fiber types use double-clad technology for maximum intensity. The light guide fibers are gently bent into a square array of holes and air-gap coupled to four compact position-sensitive photomultipliers (16 channel Hamamatsu R5900-M16). Custom electronics amplifies and converts the analog outputs to ECL pulses whichmore » are counted by VME-based scalars. The device consisting of the fibers, photomultipliers, and electronics is sealed within a light-tight aluminum box. Two modules make up a beam imaging 2-D system. The system has been tested successfully during an experimental run« less

Trotta, Richard; Torisky, Ben; Benmokhtar, Fatiha

2015-10-01

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.

Medical student burnout is prevalent, and there has been much discussion about burnout and professionalism in medical education and the clinical learning environment. Yet, few studies have attempted to explore relationships between those issues using validated instruments. Medical students were surveyed at the beginning of their fourth year using the Maslach Burnout Inventory, the Jefferson Scale of Physician Empathy-Student Version, and the Professionalism Climate Instrument. The data were analyzed using Statistical Package for the Social Sciences, and Spearman correlation analysis was performed. Scores indicative of higher medical student burnout were associated with lower medical student empathy scores and with lower professionalism climate scores observed in medical students, residents, and faculty. Investigators observed relationships between medical student burnout, empathy, and professionalism climate. These findings may have implications for the design of curriculum interventions to promote student well-being and professionalism.

The Search for Missing Baryons with Linearly Polarized Photons at Jefferson Lab

NASA Astrophysics Data System (ADS)

Cole, Philip

2006-05-01

The set of experiments forming the g8 run took place in Hall B of Jefferson Lab during the summers of 2001 and 2005 These experiments made use of a beam of linearly-polarized photons produced through coherent bremsstrahlung and represent the first time such a probe has been employed at Jefferson Lab. The scientific purpose of g8 is to improve the understanding of the underlying symmetry of the quark degrees of freedom in the nucleon, the nature of the parity exchange between the incident photon and the target nucleon, and the mechanism of associated strangeness production in electromagnetic reactions. With the high-quality beam of the tagged and collimated linearly-polarized photons and the nearly complete angular coverage of the Hall-B spectrometer, we seek to extract the differential cross sections and attendant polarization observables for the photoproduction of vector mesons and kaons at photon energies ranging between 1.3 and 2.2 GeV. We achieved polarizations exceeding 90% and collected over six billion events, which, after our data cuts and analysis, should give us well over 100 times the world's data set. I shall report on the experimental details of establishing the Coherent Bremsstrahlung Facility and present some preliminary results from our first run.

First report of Jefferson's ground sloth (Megalonyx jeffersonii) in North Dakota: Paleobiogeographical and paleoecological significance

2007-01-01

A well-preserved ungual of a pes documents the presence of Jefferson's ground sloth (Megalonyx jeffersonii) at the end of the Wisconsinan in North Dakota. This is the 1st report of M. jeffersonii in North Dakota, and one of few records from the upper Great Plains. An accelerator mass spectrometer radiocarbon age of 11,915 ?? 40 years ago was obtained from the specimen, suggesting that the sloth resided in North Dakota during the Rancholabrean Land Mammal Age, just before extinction of the species. Palynological records from sites near the sloth occurrence and of the same age indicate that it resided in a cool, moist, spruce-dominated forest habitat in a riparian setting along the Missouri River. Its presence in that setting corroborates the notion that Jefferson's ground sloth was a browsing inhabitant of gallery forests associated with rivers. It is likely that M. jeffersonii used river valleys, such as the Missouri River valley, as migration routes. ?? 2007 American Society of Mammalogists.

Although appropriate empathy in health professionals is essential, a loss of empathy can occur during medical education. The structure of clinical learning may be one factor that is implicated in a loss of empathy. This study examines student and doctor empathy, and possible associations between empathy and the structure of clinical learning. There were three groups of participants: medical students (n = 281), who completed a longitudinal survey consisting of the Jefferson Scale of Empathy and an open question about empathy at the beginning and end of the 2013 academic year; private doctors (medical practitioners) in South Australia (n = 78) who completed a survey consisting of the Jefferson Scale of Empathy and an open question about empathy at the end of the students' academic year; and doctors (medical practitioners) from public teaching hospitals (n = 72) in southern Adelaide, South Australia who completed a survey consisting of the Jefferson Scale of Empathy at the end of the students' academic year . Year one students' empathy scores at the end of the year (102.8 ± 17.7) were significantly lower than at the start of the year (112.3 ± 9.6) p < .05). There were no other significant differences in students' empathy scores by year groups or across the two time points. Empathy scores were almost identical for private and hospital clinicians and higher than average scores for students. Free-text comments highlighted the importance students and doctors place on empathy. Students described issues that adversely affected their empathy, including specific incidents, systemic issues, and course structure, but also described some positive role models. Doctors' comments focused on the importance of empathy but qualified its meaning in the therapeutic setting. Medical students and practitioners alike ascribe importance to empathy in clinical practice, yet its developmental course remains poorly understood with possible decrement across the course

2012-01-01

Despite the emphasis placed on interdisciplinary education and interprofessional collaboration between physicians and pharmacologists, no psychometrically sound instrument is available to measure attitudes toward collaborative relationships. This study was designed to examine psychometrics of an instrument for measuring attitudes toward physician-pharmacist collaborative relationships for administration to students in medical and pharmacy schools and to physicians and pharmacists. The Scale of Attitudes Toward Physician-Pharmacist Collaboration was completed by 210 students at Jefferson Medical College. Factor analysis and correlational methods were used to examine psychometrics of the instrument. Consistent with the conceptual framework of interprofessional collaboration, three underlying constructs, namely "responsibility and accountability;" "shared authority;" and "interdisciplinary education" emerged from the factor analysis of the instrument providing support for its construct validity. The reliability coefficient alpha for the instrument was 0.90. The instrument's criterion-related validity coefficient with scores of a validated instrument (Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration) was 0.70. Findings provide support for the validity and reliability of the instrument for medical students. The instrument has the potential to be used for the evaluation of interdisciplinary education in medical and pharmacy schools, and for the evaluation of patient outcomes resulting from collaborative physician-pharmacist relationships.

Di-hadron production at Jefferson Lab

Anefalos Pereira, Sergio; et. al.,

Semi-inclusive deep inelastic scattering (SIDIS) has been used extensively in recent years as an important testing ground for QCD. Studies so far have concentrated on better determination of parton distribution functions, distinguishing between the quark and antiquark contributions, and understanding the fragmentation of quarks into hadrons. Hadron pair (di-hadron) SIDIS provides information on the nucleon structure and hadronization dynamics that complement single hadron SIDIS. Di-hadrons allow the study of low- and high-twist distribution functions and Dihadron Fragmentation Functions (DiFF). Together with the twist-2 PDFs ( f1, g1, h1), the Higher Twist (HT) e and hL functions are very interesting becausemore » they offer insights into the physics of the largely unexplored quark-gluon correlations, which provide access into the dynamics inside hadrons.

Johnson, Michael C.

2015-09-01

The beam viewer system at Jefferson Lab provides operators and beam physicists with qualitative and quantitative information on the transverse electron beam properties. There are over 140 beam viewers installed on the 12 GeV CEBAF accelerator. This paper describes an upgrade consisting of replacing the EPICS-based system tasked with managing all viewers with a mixed system utilizing EPICS and high-level software. Most devices, particularly the beam viewers, cannot be safely inserted into the beam line during high-current beam operations. Software is partly responsible for protecting the machine from untimely insertions. The multiplicity of beam-blocking and beam-vulnerable devices motivates us tomore » try a data-driven approach. The beamline insertions application components are centrally managed and configured through an object-oriented software framework created for this purpose. A rules-based engine tracks the configuration and status of every device, along with the beam status of the machine segment containing the device. The application uses this information to decide on which device actions are allowed at any given time.« less

Pair of hadrons (di-hadron) SIDIS provides information on the nucleon structure and hadronization dynamics that complements single-hadron SIDIS. The study of di-hadrons allow us to study higher twist distribution functions and Dihadron Fragmentation Functions (DiFF). Together with the twist-2 PDFs (f 1, g 1, h 1), the Higher Twist (HT) e and hL functions are very interesting because they offer insights into the physics of the largely unexplored quark-gluon correlations which provide direct and unique insights into the dynamics inside hadrons.

Hydrogeologic Factors Affecting Base-Flow Yields in the Jefferson County Area, West Virginia, October-November 2007

USGS Publications Warehouse

Evaldi, Ronald D.; Paybins, Katherine S.; Kozar, Mark D.

2009-01-01

Base-flow yields at approximately the annual 75-percent-duration flow were determined for watersheds in the Jefferson County area, WV, from stream-discharge measurements made during October 31 to November 2, 2007. Five discharge measurements of Opequon Creek defined increased flow from 29,000,000 gallons per day (gal/d) at Carters Ford to 51,400,000 gal/d near Vanville. No flow was observed at 45 of 110 additional stream sites inspected, and discharge at the 65 flowing stream sites ranged from 1,940 to 17,100,000 gallons per day (gal/d). Discharge at 28 springs ranged from no flow to 2,430,000 gal/d. Base-flow yields were computed as the change in stream-channel discharge between measurement sites divided by the change in drainage area between the sites. Yields were negative for losing (influent) channel reaches and positive for gaining (effluent) reaches. Channels in 14 watersheds were determined to have lost flow ranging from -9.6 to -1,770 gallons per day per acre (gal/d/acre). Channels in 51 watersheds were determined to have gained flow ranging from 3.4 to 235,000 gal/d/acre. Water temperature at the stream sites ranged from 5.0 to 16.3 deg C (quarry pumpage), and specific conductance ranged from 51 to 881 microsiemens per centimeter (uS/cm). Water temperature at the springs ranged from 11.5 to 15.0 deg C, and specific conductance ranged from 22 to 958 uS/cm. Large springs in some watersheds in western Jefferson County are adjacent to other watersheds with little or no surface-water discharge; this is probably the result of interbasin transfer of groundwater along faults that dissect the area. Most watersheds located adjacent to the Potomac River in northeastern Jefferson County were not flowing during this study; this is most likely because the Potomac River is deeply incised, and groundwater flows directly to it rather than to the local stream systems in these areas. Except for one watershed with a yield of 651 gal/d/acre, no watersheds in northeastern

The primary focus of the study was to determine whether coursework in the medical humanities would ameliorate students' loss of and failure to develop empathy, a problem known to be common during medical education. Students were offered an elective course in the Medical Humanities for academic credit. The Jefferson Scale of Empathy Student Version (JSE-S) was administered at the beginning and end of an academic year in which humanities courses were offered. Changes in JSE-S scores among students who studied Medical Humanities were compared with changes in student who did not take any humanities coursework. Medical humanities coursework correlated with superior empathy outcomes among the medical students. Of students not enrolled in humanities courses, 71% declined or failed to increase in JSE-S score over the academic year. Of those who took humanities coursework, 46% declined or failed to increase in JSE-S scores. The difference was statistically significant (P = .03). The medical humanities curriculum correlated with favorable empathy outcomes as measured by the JSE-S. Elective medical humanities coursework correlated with improved empathy score outcomes in a group of US medical students. This may reflect a direct effect of the humanities coursework. Alternately, students' elective choice to take medical humanities coursework may be a marker for students with a propensity to favorable empathy outcomes. Copyright © 2016 Elsevier Inc.

To identify similarities and differences in empathy, abilities toward inter-professional collaboration, and lifelong medical learning, between Spanish and Latin-American physicians-in-training who start their posgraduate training in teaching hospitals in Spain. Observational study using self-administered questionnaires. Five teaching hospitals in the province of Barcelona, Spain. Spanish and Latin-American physicians-in-training who started their first year of post-graduate medical training. Empathy was measured using the Jefferson scale of empathy. Abilities for inter-professional collaboration were measured using the Jefferson scale attitudes towards nurse-physician collaboration. Learning was measured using the Jefferson scale of medical lifelong learning scale. From a sample of 156 physicians-in-training, 110 from Spain and 40 from Latin America, the Spanish group showed the highest empathy (p<.05). On the other hand, Latin-American physicians had the highest scores in lifelong learning abilities (p<.001). A positive relationship was found between empathy and inter-professional collaboration for the whole sample (r=+0.34; p<.05). These results confirm previous preliminary data and underline the positive influence of empathy in the development of inter-professional collaboration abilities. In Latin-American physicians who start posgraduate training programs, lifelong learning abilities have a positive influence on the development of other professional competencies.

Nakamura, Satoshi; Gogami, Toshiyuki; Tang, Liguang

The missing mass spectroscopy of L hypernuclei with the (e, e'K^+) reaction was started from 2000 at Jefferson Lab. In this fifteen years, various hypernuclei (A = 7 - 52) including hyperon (L, S^0) productions have been studied with newly developed experimental techniques. The (e, e'K^+) reaction spectroscopy of L hypernuclei features its capability of absolute missing mass calibration and production of new species of hypernuclei which are the isospin partners of well studied hypernuclei by (K^-, pi-) and (pi^+, K^+) reactions. In this paper, we will review how we established the (e, e'K^+) spectroscopic study of hypernuclei.

2009-12-01

A large part of the experimental program in Hall B of the Jefferson Lab is dedicated to baryon spectroscopy. Photoproduction experiments are essential part of this program. CEBAF Large Acceptance Spectrometer (CLAS) and availability of circularly and linearly polarized tagged photon beams provide unique conditions for this type of experiments. Recent addition of the Frozen Spin Target (FROST) gives a remarkable opportunity to measure double and triple polarization observables for different pseudo-scalar meson photoproduction processes. For the first time, a complete or nearly complete experiment becomes possible and will allow model independent extraction of the reaction amplitude. An overview ofmore » the experiment and its current status is presented.« less

Exploration and confirmation of the latent variable structure of the Jefferson scale of empathy

PubMed Central

LaNoue, Marianna

2014-01-01

Objectives: To reaffirm the underlying components of the JSE by using exploratory factor analysis (EFA), and to confirm its latent variable structure by using confirmatory factor analysis (CFA). Methods Research participants included 2,612 medical students who entered Jefferson Medical College between 2002 and 2012. This sample was divided into two groups: Matriculants between 2002 and 2007 (n=1,380) and between 2008 and 2012 (n=1,232). Data for 2002-2007 matriculants were subjected to EFA (principal component factor extraction), and data for matriculants of 2008-2012 were used for CFA (structural equation modeling, and root mean square error for approximation). Results The EFA resulted in three factors: “perspective-taking,” “compassionate care” and “walking in patient’s shoes” replicating the 3-factor model reported in most of the previous studies. The CFA showed that the 3-factor model was an acceptable fit, thus confirming the latent variable structure emerged in the EFA. Corrected item-total score correlations for the total sample were all positive and statistically significant, ranging from 0.13 to 0.61 with a median of 0.44 (p<0.01). The item discrimination effect size indices (contrasting item mean scores for the top-third versus bottom-third JSE scorers) ranged from 0.50 to 1.4 indicating that the differences in item mean scores between top and bottom scorers on the JSE were of practical importance. Cronbach’s alpha coefficient of the JSE for the total sample was 0.80, ranging from 0.75 to 0.84 for matriculatnts of different years. Conclusions Findings provided further support for underlying constructs of the JSE, adding to its credibility. PMID:25341215

2006-10-01

Jefferson Lab experiment E00-002 aims to measure inclusive electron-proton and electron-deuteron scattering cross section at low Q squared and moderately low Bjorken x. Data in this kinematic region will further our understanding of the transition between the perturbative and non-perturbative regimes of Quantum Chromodynamics (QCD). As part of the data analysis effort underway at James Madison University (JMU) a comprehensive set of checks and tests was implemented. These tests ensure the quality and consistency of the experimental data, as well as providing, where appropriate, correction factors between the experimental apparatus as used and its idealized computer-simulated representation. This contribution will outline this testing procedure as implemented in the JMU analysis, highlighting the most important features/results.

Empathy is a core element in the doctor-patient relationship. This study examined whether empathy in medical students can be improved by specific training. 158 medical students were randomized into two groups. The intervention group participated in an empathy skills training with simulated patients (SPs). The control group participated in a history course. After the intervention, empathy was assessed by blinded SPs and experts in an Objective Structured Clinical Examination (OSCE). Students also filled out a self-assessment concerning their attitude on empathy (Jefferson Scale of Physician Empathy Student Version, JSPE-S-S). Participants of the intervention group showed significantly higher levels of empathy when rated by SPs and experts than the control group. In contrast to that, no significant group differences were observed in self-rated empathy. The results underpin the value of empathy skills trainings in medical school study programs.

The construction of a thin vacuum window, currently in use on the CLAS photon tagging system at the Thomas Jefferson National Accelerator Facility, is described. A layer of woven Kevlar cloth supports a much thinner membrane of aluminized Mylar. Notable features of this particular window include its overall length (9.6 m), and the fact that the entire load is supported by the epoxy seal with no mechanical clamping around the edges. Results from a diverse program of materials testing, including a clear dependence of leak rate on relative humidity, are also reported.

We report on our interdisciplinary program to use the Free Electron Laser (FEL) at the Thomas Jefferson National Accelerator Facility (J-Lab) for high-volume pulsed laser vaporization synthesis of carbon nanotubes. Based in part on the funding of from this project, a novel nanotube production system was designed, tested, and patented. Using this new system nanotube production rates over 100 times faster than conventional laser systems were achieved. Analysis of the material produced shows that it is of as high a quality as the standard laser-based materials.

A 15-year review of railway-related deaths in Jefferson County, Alabama.

1997-12-01

A retrospective computer search of the records of the Jefferson County Coroner/Medical Examiner Office covering the 15-year period from 1981 to 1995 revealed 86 cases in which either a train caused death or in which a body was found dead by the tracks. The average age of the decedents was 39 years (range, 3 weeks-87 years). Men accounted for 88% of the deaths. The manners of death were as follows: three natural, 64 accident, seven suicide, six homicide, and six undetermined. Six decedents were found dead by the tracks, but death was not caused by a train. Six decedents were railroad employees who died on the job. In 47 cases, the decedents were trespassing on railroad property. Five trespassers were riding the rails, and 42 were pedestrians struck by a train. Motor vehicle collisions with trains claimed 27 lives--19 drivers and eight passengers. All together, 45% of the decedents were intoxicated. Intoxication was greatest by far in individuals witnessed to have been lying on the tracks before being hit by a train. The nature of individuals riding the rails has changed in the past few decades. Freight trains today are being used by illegal immigrants as transportation within the United States. The majority of traffic fatalities occurred because the driver intentionally tried to beat the train to the crossing. These drivers were seldom intoxicated, and only two were teenagers. Lives of such impatient drivers might be spared by the installation of a crossing guard-rail that cannot be circumvented.

1999-05-01

This study was designed to compare male and female medical students on selected personality attributes that could influence their academic attainment and personal success. Participants were 1157 medical students (743 men, 414 women) who completed a set of psychosocial questionnaires measuring intensity and chronicity of loneliness, general anxiety, test anxiety, neuroticism, depression, extraversion, self-esteem, locus of control, perceptions of parents, general health and appraisals of stressful life events. Data were analysed by employing multivariate and univariate analysis of variance and chi-square analysis. Jefferson Medical College. Medical students. Men scored significantly higher on the intensity of loneliness, and women scored higher on general anxiety, test anxiety and neuroticism scales, but the magnitudes of the effect size estimates were not large. No significant gender difference was observed on measures of chronicity of loneliness, depression, extraversion, self-esteem, external locus of control, perception of general health and perceptions of the mother and the father. Women who experienced stressful life events, such as death in the family or personal illness, appraised these events more negatively than did their male counterparts. Implications of the findings for medical education and practice are discussed.

Cultural resource applications for a GIS: Stone conservation at Jefferson and Lincoln Memorials

Geographical information systems are rapidly becoming essential tools for land management. They provide a way to link landscape features to the wide variety of information that managers must consider when formulating plans for a site, designing site improvement and restoration projects, determining maintenance projects and protocols, and even interpreting the site. At the same time, they can be valuable research tools.Standing structures offer a different sort of geography, even though a humanly contrived one. Therefore, the capability of a geographical information system (GIS) to link geographical units to the information pertinent to the site and resource management can be employed in the management of standing structures. This was the idea that inspired the use of a GIS software, ArcView, to link computer aided design CAD) drawings of the Jefferson and Lincoln Memorials with inventories of the stones in the memorials. Both the CAD drawings and the inventory were in existence; what remained to be done was to modify the CAD files and place the inventory in an appropriately designed computerized database, and then to link the two in a GIS project. This work was carried out at the NPS Denver Service Center, Resource Planning Group, Applied Archaeology Center (DSC-RPG-AAC), in Silver Spring, Maryland, with the assistance of US/ICOMOS summer interns Katja Marasovic (Croatia) and Rastislav Gromnica (Slovakia), under the supervision of AAC office manager Douglas Comer. Project guidance was provided by Tony Donald, the Denver Service Center (DSC) project architect for the restoration of the Jefferson and Lincoln Memorials, and GIS consultation services by Kyle Joly.

Petrographic and geochemical investigation of magma chamber processes beneath small Quaternary volcanic centers between Mt. Jefferson and Mt. Hood volcanoes, Cascade Range Volcanic Arc

NASA Astrophysics Data System (ADS)

Cunningham, E.; Cribb, J. W.

2017-12-01

The northern Oregon Cascade Range has been dominated by andesite to rhyodacite lavas at both Mt. Jefferson (Conrey, 1991) and at Mt. Hood (Cribb and Barton, 1996) during the Quaternary period. Eruptive sequences at both Mt. Hood and Mt. Jefferson have been attributed to open-system mama mixing (Kent et al., 2010) (Ferrell et al., 2015), and the narrow range of lavas erupted at both centers has been derived from repeated cycles of magma mixing-fractionation (Cribb and Barton, 1996). This research examines major and trace element geochemistry as well as the petrographic characteristics of Clear Lake Butte (CLB), Pinhead Butte (PB), and Olallie Butte (OB), all of which are located between Mt. Hood and Mt. Jefferson, and have ben active in the Quaternary period. The research investigates whether the same type of open-system magma mixing known to have occurred at Mt. Hood and Mt. Jefferson has also occurred at CLB, PB, or OB, or whether those systems were closed to mixing and dominated by fractional crystallization. One of the main goals of this project is to highlight the similarities and differences exhibited by neighboring magmatic systems of similar age, but different scale. Disequilibrium textures observed in thin sections from CLB, OB, and PB suggest open-system magma mixing is likely occurring beneath all three buttes. This petrographic evidence includes plagioclase and pyroxene zoning, embayed margins, sieving, and reaction rims. Major element oxide trends at all three buttes are consistent with fractional crystallization, but show narrow concentrations and non-overlapping compositions between PB, CLB, and OB. All three buttes are characterized by narrow ranges of incompatible and compatible trace element concentrations. CLB, PB, and OB all exhibit LREE enrichment and lack significant HFSE depletions, with PB exhibiting greatest enrichment in REE.

The photon arm of the Compton polarimeter in Hall A of Jefferson Lab has been upgraded to allow for electron beam polarization measurements with better than 1% accuracy. The data acquisition system (DAQ) now includes an integrating mode, which eliminates several systematic uncertainties inherent in the original counting-DAQ setup. The photon calorimeter has been replaced with a Ce-doped Gd 2SiO 5 crystal, which has a bright output and fast response, and works well for measurements using the new integrating method at electron beam energies from 1 to 6 GeV.

To examine, primarily, the effects of ethnicity and gender, which could introduce bias into scoring, on standardized patient (SP) assessments of medical students and, secondarily, to examine medical students' self-reported empathy for ethnicity and gender effects so as to compare self-perception with the perceptions of SPs. Participants were 577 students from four medical schools in 2012: 373 (65%) were white, 79 (14%) black/African American, and 125 (22%) Asian/Pacific Islander. These students were assessed by 84 SPs: 62 (74%) were white and 22 (26%) were black/African American. SPs completed the Jefferson Scale of Patient Perceptions of Physician Empathy (JSPPPE) and the Global Ratings of Empathy tool. Students completed the Jefferson Scale of Empathy and two Interpersonal Reactivity Index subscales. The investigators used 2,882 student-SP encounters in their analyses. Analyses of SPs' assessments of students' empathy indicated significant interaction effects of gender and ethnicity. Female students, regardless of ethnicity, obtained significantly higher mean JSPPPE scores than men. Female black/African American, female white, and female Asian/Pacific Islander students scored significantly higher on the JSPPPE than their respective male counterparts. Male black/African American students obtained the lowest SP assessment scores of empathy regardless of SP ethnicity. Black/African American students obtained the highest mean scores on self-reported empathy. The significant interaction effects of ethnicity and gender in clinical encounters, plus the inconsistencies observed between SPs' assessments of students' empathy and students' self-reported empathy, raise questions about possible ethnicity and gender biases in the SPs' assessments of medical students' clinical skills.

To examine if the empathy levels of first-year medical students are amenable to didactic interventions idealized to promote values inherent to medical professional identity. This is a pretest-posttest study designed to assess the empathy levels of first-year medical students (n=166) comprising two consecutive classes of a Brazilian medical school, performed before and after a didactic intervention. Students attended a course based on values and virtues related to medical professional identity once a week over four months. Every didactic approach (interviews with patients and physicians, supervised visits to the hospital, and discussion of videotaped simulated consultations) was based on "real-world" situations and designed to promote awareness of the process of socialization. Students filled out the Jefferson Scale of Physician Empathy (JSPE) on the first and last days of this course, and the pretest-posttest analysis was performed using the Wilcoxon Signed Rank Test. The mean pretest JSPE score was 117.9 (minimum 92, maximum 135) and increased to 121.3 after the intervention (minimum 101, maximum 137). The difference was significant (z=-5.2, p<.001.), with an effect size of 0.40. The observed increase was greater among students with lower initial JSPE scores. Empathy is a fundamental tool used to achieve a successful physician-patient relationship, and it seems to permeate other virtues of a good physician. This study's results suggest that medical students' empathy may be amenable to early curricular interventions designed to promote a positive development of their professional identity, even when empathy is not central in discussion.

Jefferson fractures are rare prior to teen-age. Three young children examined after trauma exhibited the characteristic spread appearance of the atlas, but fractures were excluded radiographically and clinically. A retrospective study demonstrated a similar appearance, termed pseudospread, in most children aged 3 months to 4 years, including over 90% during the second year. Pseudospread results from a discrepancy between the neural growth pattern of the atlas and the somatic pattern of the axis. An atlas spread index is defined and a normal range presented.

Jefferson County Open Space Parks, as well as other nearby parks and National Forest lands, offer marvelousopportunities to explore the geologic story behind this singular landscape. At first the distribution of rocks of differentages and types seems almost random, but careful study of the rocks and landscape features reveals a captivatinggeologic story, a history that tells of the building of the foundations of the continent, the rise and destruction of longvanishedmountain ranges, the ebb and flow of ancient seas, and the constant shaping and reshaping of the landscape inresponse to the never-ending interplay between uplift and erosion. This historical account is constantly being improvedand expanded as new evidence accumulates and new interpretations evolve.

The only Confederate president, Jefferson Davis, led a long and eventful life. He was a Mississippi planter, a husband, a father, West Point graduate, war hero, congressman, senator, secretary of war, and finally President of the Confederate States of America. In many ways he was a study of contrast with his northern counterpart Abraham Lincoln. Davis was personally courageous and a rich, educated, southern aristocrat who did not deeply understand the political process or have the refined personal skills necessary to work well with others. Prior to his Presidency he served with distinction in two wars, but as a result of his confederate activity and pro-slavery philosophy he is one of the least discussed famous Americans. Davis's health was a constant problem and he suffered an almost fatal attack of 'malaria' in 1836. In the winter of 1857-1858, he again was seriously ill and by the end of February 1858, a chronic, relapsing, ocular inflammatory condition began. Using historical evidence from multiple sources, this paper will propose a diagnosis of the Confederate President's ocular condition and consider how this could have influenced his military and political decisions.

Why teaching empathy is important for the medical degree.

PubMed

Díez-Goñi, N; Rodríguez-Díez, M C

Empathy is a basic skill in the exercise of medicine and increases patient and physician satisfaction and improves clinical results. However, the teaching of empathy is poorly covered in the teaching plans. A number of studies have observed a reduction in empathy during the final training courses. The reasons for this decline include, the students' excessive academic workload, the prioritisation of acquiring medical expertise over humanistic knowledge, the patient load in hospitals and health centres and the physicians' need to distance themselves from their patients. Nevertheless, intervention studies through simulation with standardised patients have shown an increase in empathy in students, which can be evaluated through the Jefferson scales: JSE-S and JSPPPE. The teaching of empathy to medical students is an important commitment in the curricular programs of medical schools.

Empathy is a crucial skill for medical students that can be difficult to evaluate. We examined if self-reported empathy in medical students was associated with clinical competence. This study combined cross-sectional data from four consecutive years of medical students (N=590) from the Boston University School of Medicine. We used regression analysis to evaluate if self-reported empathy (Jefferson Scale of Physician Empathy (JSPE)) predicted scores in clinical clerkships, United States Medical Licensing Examinations, and OBJECTIVE: Structured Clinical Examinations (OSCEs). We separately analyzed overall and OSCE communication scores based on interpersonal skills reported by standardized patients. We controlled for age, gender, debt, and specialty affinity. JSPE scores of medical students were positively associated with OSCE communication scores, and remained significant when controlling for demographics. We found that JSPE score was also predictive of overall OSCE scores, but this relationship was confounded by gender and age. JSPE scores were associated with performance in the Pediatrics clerkship, but not other clerkships or standardized tests. JSPE scores were positively associated with OSCE communication scores in medical students. This study supports that self-reported empathy may predict OSCE performance, but further research is needed to examine differences by gender and age. Copyright © 2016 Elsevier Ireland Ltd.

The Generic Lock system is a software framework that allows highly flexible feedback control of large distributed systems. It allows system operators to implement new feedback loops between arbitrary process variables quickly and with no disturbance to the underlying control system. Several different types of feedback loops are provided and more are being added. This paper describes the further evolution of the system since it was first presented at ICALEPCS 2001 and reports on two years of successful use in accelerator operations. The framework has been enhanced in several key ways. Multiple-input, multiple-output (MIMO) lock types have been added formore » accelerator orbit and energy stabilization. The general purpose Proportional-Integral-Derivative (PID) locks can now be tuned automatically. The generic lock server now makes use of the Proxy IOC (PIOC) developed at Jefferson Lab to allow the locks to be monitored from any EPICS Channel Access aware client.

With a new Compton polarimeter we aim to measure the beam polarization with a statistical precision of 1% in one hour and a systematic uncertainty of 1%. A low-gain Fabry-Perot cavity laser system provides the circularly polarized photons. The scatteredmore » electrons are detected in radiation-hard diamond strip detectors, and form the basis for a coincidence trigger using distributed logic boards. The photon detector uses a fast, undoped CsI crystal with simultaneous sampling and integrating read-out. Coincident events are used to cross-calibrate the photon and electron detectors.« less

Charles, Gabriel; CLAS Collaboration Collaboration

2017-01-01

Part of the experimental program in Hall B of the Jefferson Lab is dedicated to studying nucleon structure using DIS on nuclei and detecting low-momentum recoil particles in coincidence with the scattered electron. For this purpose, specially designed central detectors are required in place of the inner tracker of CLAS12 to detect particles with momenta below 100 MeV/c. We will present the status of the BONuS12 RTPC detector that will take data within the next 2 years. We will detail the main improvements made from the previous BONuS RTPC. In a second part, we will discuss another recoil experiment, called ALERT, that has been proposed to run in Hall B. The constraints being different, the recoil detector is based on a drift chamber and an array of scintillators. We will present the main differences between the two detectors and summarize the R&D performed to develop the ALERT detector.

The purpose of this study was to investigate the influence of spirituality, religiosity, personal beliefs, and previous contact with health issues on the level of empathy in medical students. Jefferson Scale of Empathy-Student Version, WHOQOL-Spirituality, Religiousness and Personal Beliefs, and Duke University Religion Index were applied to 285 Brazilian medical students. The findings suggest that meaning of life and previous mental health treatment but not Religiosity were positively related to empathy. We suggest that more attention should be given for prevention and treatment of mental health issues, and further studies are needed to understand and replicate these findings.

2012-11-01

The aim of this research was to explore the increasingly popular Dutch health phenomenon of 'gathering in private peer group settings (barracks)', with a focus on the prevalence and characteristics of barracks, alcohol consumption, and other (risk) behaviors of their visitors. Three studies were conducted. The first consisted of field research in which 51 barracks were visited and group-interviews were held. The second was an Internet study in which 442 barracks' websites were analyzed using content analysis. The third consisted of a questionnaire completed by 1457 adolescents, aged 15-17, in order to explore differences in behavior between barracks visitors and non-visitors. There was wide variation in barracks' characteristics and culture. Barracks' members and visitors also organize diverse activities that are publicly shown on the websites. Barracks are associated with various legal issues, such as alcohol sales to minors, lack of parental supervision, and illicit drug use. Barracks' visitors drink alcohol more frequently, drink more alcohol per occasion (up to fifteen bottles of beer a night), and have been drunk more frequently than non-visitors. Policymakers must be aware of the barracks phenomenon and use their powers in adjacent political and legal areas (such as in binge drinking, illicit drug use, and public safety) to intervene and create solid, responsible, and tailor-made policies.

Latest progress of ILC high gradient SRF cavity R&D at Jefferson Lab will be presented. 9 out of 10 real 9-cell cavities reached an accelerating gradient of more than 38 MV/m at a unloaded quality factor of more than 8 {center_dot} 109. New understandings of quench limitation in 9-cell cavities are obtained through instrumented studies of cavities at cryogenic temperatures. Our data have shown that present limit reached in 9-cell cavities is predominantly due to localized defects, suggesting that the fundamental material limit of niobium is not yet reached in 9-cell cavities and further gradient improvement is still possible. Somemore » examples of quench-causing defects will be given. Possible solutions to pushing toward the fundamental limit will be described.« less

The highest concentration of lakes dammed by Neoglacial moraines in the conterminous United States is in the Mount Jefferson and Three Sisters Wilderness Areas in central Oregon. Between 1930 and 1980, breakouts of these lakes have resulted in 11 debris flows. The settings and sequences of events leading to breaching and the downstream flow behavior of the resulting debris flows provide guidance on the likelihood and magnitude of future lake breakouts and debris flows.

Jefferson Lab plays an active role in high-gradient SRF R&D in the frame work of the internationally coordinated ILC S0 program. The S0 aim is to push the yield at 35 MV/m in 9-cell cavities. So far, twelve cavities have been electropolishing (EP) processed and RF tested by using the state-of-the-art recipes at JLab, in close collaboration with FNAL and KEK. Seven of them reached a best gradient of over 31.5 MV/m. Understanding gradient limiting mechanisms in real 9-cell cavities is an important component of our studies. Thermometry and high-resolution optical inspection are used to locate and understand the sourcemore » of gradient limits. Experimenting with selective cavities is still a necessary method for process optimization. One example is the first demonstration of 35 MV/m without detectable Bremsstrahlung X-ray after a light EP is applied to a previously heavy BCP etched 7-cell cavity.

Scaling behavior in exclusive meson photoproduction from Jefferson Lab at large momentum transfers

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

2014-07-01

With the availability of new high-statistics and wide-angle measurements for several exclusive non-πN meson photoproduction channels from Jefferson Lab, we examine the fundamental scaling law of 90° scattering in QCD that was originally derived in the high-energy perturbative limit. The data show scaling to be prominently visible even in the medium-energy domain of 2.5 GeV ≲√s≲2.84 GeV, where √s is the center-of-mass energy. While constituent quark exchange suffices for pseudoscalar mesons, additional gluon exchanges from higher Fock states of the hadronic wave functions appear be needed for vector-meson production. Finally, the case of the Φ(1020), where two-gluon exchanges are knownmore » to dominate, is especially illuminating.« less

Measurement of parity-violating asymmetry in deep inelastic scattering at Jefferson Lab

NASA Astrophysics Data System (ADS)

Zheng, Xiaochao

2015-04-01

Symmetry permeates nature and is fundamental to all laws of physics. One example is mirror symmetry, also called ``parity symmetry''. It implies that flipping left and right does not change the laws of physics. Laws for electromagnetism, gravity and the subatomic strong force respect parity symmetry, but the subatomic weak force does not. Historically, parity violation in electron scattering played a key role in establishing, and now testing, the Standard Model of particle physics. One particular set of the quantities accessible through measurements of parity-violating electron scattering are the vector-electron axial-vector-quark weak couplings, called C2 q's, measured directly only once in the past 40 years. We report here on a new measurement of the parity-violating asymmetry in electron-quark scattering, that has yielded a specific combination 2C2 u -C2 d five times more precise than the earlier result. (Here u and d stand respectively for the up and the down quarks.) These results are the first evidence, at more than the 95% confidence level, that the C2 q's are non-zero as predicted by the electroweak theory. They lead to constraints on new interactions beyond the Standard Model, particularly on those whose laws change when the quark chirality is flipped between left and right. In today's particle physics research that is focused on colliders such as the LHC, our results provide specific chirality information on electroweak theory that is difficult to obtain at high energies. In addition to deep inelastic scattering, we will report on measurement of the asymmetry in the nucleon resonance region. These data exhibit for the first time that the quark-hadron duality may work for electroweak observables at the (10--15)% level throughout the whole resonance region. At the end I will give a brief outlook on the future PVDIS program using the Jefferson Lab 12 GeV beam, which will not only provide more precise measurement of C2 q, but also for sin2 θW and for

Medical student empathy: interpersonal distinctions and correlates.

PubMed

Jordan, Kevin D; Foster, Penni Smith

2016-12-01

Attention to interpersonal behaviors, communication, and relational factors is taking on increasing importance in medical education. Medical student empathy is one aspect of the physician-patient relationship that is often involved in beneficial interactions leading to improved clinical outcomes and patient satisfaction. As an interpersonal quality, empathy is a social behavior well-suited to be examined from an interpersonal perspective. The present study used the interpersonal theory of clinical, personality, and social psychology to examine the construct of empathy and theorize about likely interpersonal correlates. One hundred and sixty-three students from an academic health center in the southeastern United States participated in this study. The medical student version of the Jefferson Scale of Empathy was used to assess empathy and its factors: Perspective taking, compassionate care, and walking in the patient's shoes. Interpersonal assessments included the International Personality Item Pool-Interpersonal Circumplex, the Interpersonal Support Evaluation List, and the UCLA Loneliness Scale. Distinct interpersonal styles and correlates emerged among empathy and its factors. While all factors of empathy were related to interpersonal warmth, perspective taking and compassionate care were also associated with submissiveness. Of note, only walking in the patient's shoes was correlated with both social support and less loneliness. These findings are discussed in light of interpersonal theory with particular attention paid to the implications for medical education and professional development.

2008-01-01

On November 6, 2006, a rocky debris flow surged off the western slopes of Mount Jefferson into the drainage basins of Milk and Pamelia Creeks in Oregon. This debris flow was not a singular event, but rather a series of surges of both debris and flooding throughout the day. The event began during a severe storm that brought warm temperatures and heavy rainfall to the Pacific Northwest. Precipitation measurements near Mount Jefferson at Marion Forks and Santiam Junction showed that more than 16.1 centimeters of precipitation fell the week leading up to the event, including an additional 20.1 centimeters falling during the 2 days afterward. The flooding associated with the debris flow sent an estimated 15,500 to 21,000 metric tons, or 9,800 to 13,000 cubic meters, of suspended sediment downstream, increasing turbidity in the North Santiam River above Detroit Lake to an estimated 35,000 to 55,000 Formazin Nephelometric Units. The debris flow started small as rock and ice calved off an upper valley snowfield, but added volume as it eroded weakly consolidated deposits from previous debris flows, pyroclastic flows, and glacial moraines. Mud run-up markings on trees indicated that the flood stage of this event reached depths of at least 2.4 meters. Velocity calculations indicate that different surges of debris flow and flooding reached 3.9 meters per second. The debris flow reworked and deposited material ranging in size from sand to coarse boulders over a 0.1 square kilometer area, while flooding and scouring as much as 0.45 square kilometer. Based on cross-sectional transect measurements recreating pre-event topography and other field measurements, the total volume of the deposit ranged from 100,000 to 240,000 cubic meters.

Jefferson Teamwork Observation Guide (JTOG): An Instrument to Observe Teamwork Behaviors.

PubMed

Lyons, Kevin J; Giordano, Carolyn; Speakman, Elizabeth; Smith, Kellie; Horowitz, June A

2016-01-01

Interprofessional education (IPE) is becoming an integral part of the education of health professions students. However, teaching students to become successful members of interprofessional teams is complex, and it is important for students to learn the combinations of skills necessary for teams to function effectively. There are many instruments available to measure many features related to IPE. However, these instruments are often too cumbersome to use in an observational situation since they tend to be lengthy and contain many abstract characteristics that are difficult to identify. The Jefferson Teamwork Observation Guide (JTOG) is a short tool that was created for students early in their educational program to observe teams in action with a set of guidelines to help them focus their observation on behaviors indicative of good teamwork. The JTOG was developed over a 2-year period based on student and clinician feedback and the input of experts in IPE. While initially developed as a purely educational tool for prelicensure students, it is becoming clear that it is an easy-to-use instrument that assesses the behavior of clinicians in practice.

Undergraduate medical students’ empathy: current perspectives

PubMed Central

Quince, Thelma; Thiemann, Pia; Benson, John; Hyde, Sarah

2016-01-01

Empathy is important to patient care. It enhances patients’ satisfaction, comfort, self-efficacy, and trust which in turn may facilitate better diagnosis, shared decision making, and therapy adherence. Empathetic doctors experience greater job satisfaction and psychological well-being. Understanding the development of empathy of tomorrow’s health care professionals is important. However, clinical empathy is poorly defined and difficult to measure, while ways to enhance it remain unclear. This review examines empathy among undergraduate medical students, focusing upon three main questions: How is empathy measured? This section discusses the problems of assessing empathy and outlines the utility of the Jefferson Scale of Empathy – Student Version and Davis’s Interpersonal Reactivity Index. Both have been used widely to assess medical students’ empathy. Does empathy change during undergraduate medical education? The trajectory of empathy during undergraduate medical education has been and continues to be debated. Potential reasons for contrasting results of studies are outlined. What factors may influence the development of empathy? Although the influence of sex is widely recognized, the impact of culture, psychological well-being, and aspects of undergraduate curricula are less well understood. This review identifies three interrelated issues for future research into undergraduate medical students’ empathy. First, the need for greater clarity of definition, recognizing that empathy is multidimensional. Second, the need to develop meaningful ways of measuring empathy which include its component dimensions and which are relevant to patients’ experiences. Medical education research has generally relied upon single, self-report instruments, which have utility across large populations but are limited. Finally, there is a need for greater methodological rigor in investigating the possible determinants of clinical empathy in medical education. Greater

The effect of Mind Body Medicine course on medical student empathy: a pilot study.

PubMed

Chen, Allen K; Kumar, Anagha; Haramati, Aviad

Empathy among medical practitioners has been shown to affect patient care and outcomes. Factors such as stress and depression are known to have a negative impact on medical student empathy. Approaches such as mindfulness, meditation, and other mind-body techniques can enhance empathy and reverse burnout symptoms. In the present study, we evaluated impact of Mind Body Medicine (MBM) course on perceived stress and empathy on first-year medical students. Thirteen first-year medical students in total self-selected into MBM (experimental) and seven non-MBM (control) groups completed a prospective, pre- and post-test analysis, using the Jefferson Scale of Physician Empathy - Students (JSPE-S), Perceived Stress Scale (PSS), and Personal Health Questionnaire (PHQ) to evaluate empathy, stress, and depression, respectively. Our results showed an increase in stress, as well as a decrease in empathy, in both MBM and non-MBM groups throughout the course of the study. Our study demonstrated that the inverse relationship increased stress and decreased empathy among first-year medical students and participation in the MBM course did not attenuate the changes. However, a statistically significant rise in the depression score in the non-MBM group was not observed in the MBM group.

To compare empathic orientation among medical students from three schools of medicine in Colombia and one in the Dominican Republic. Empathic orientation of medical students was measured using the Jefferson Scale of Physician Empathy (JSPE), Spanish version for students (the "S" version) validated in Mexico and Chile, and culturally adapted to Colombia and the Dominican Republic. Data were compared using a three-factor analysis of variance (model III) and a discriminant analysis. No differences in empathic orientation were observed among courses and between sexes, but differences were found in schools of medicine considered as a unit in each studied country. Empathic orientation levels tend to reduce as courses advance. This was observed in both male and female students and in all schools analyzed.

Empathy is an important component of physician competence that needs to be enhanced. To test the hypotheses that medical students' empathy can be enhanced and sustained by targeted activities. This was a two-phase study in which 248 medical students participated. In Phase 1, students in the experimental group watched and discussed video clips of patient encounters meant to enhance empathic understanding; those in the control group watched a documentary film. Ten weeks later in Phase 2 of the study, students who were in the experimental group were divided into two groups. One group attended a lecture on empathy in patient care, and the other plus the control group watched a movie about racism. The Jefferson Scale of Empathy (JSE) was administered pre-post in Phase 1 and posttest in Phase 2. In Phase 1, the JSE mean score for the experimental group improved significantly (p < 0.01); no change in the JSE scores was observed in the control group. In Phase 2, the JSE mean score improvement was sustained in the group that attended the lecture, but not in the other group. No change in empathy was noticed in the control group. Research hypotheses were confirmed.

Can empathy, other personality attributes, and level of positive social influence in medical school identify potential leaders in medicine?

PubMed

Hojat, Mohammadreza; Michalec, Barret; Veloski, J Jon; Tykocinski, Mark L

2015-04-01

To test the hypotheses that medical students recognized by peers as the most positive social influencers would score (1) high on measures of engaging personality attributes that are conducive to relationship building (empathy, sociability, activity, self-esteem), and (2) low on disengaging personality attributes that are detrimental to interpersonal relationships (loneliness, neuroticism, aggression-hostility, impulsive sensation seeking). The study included 666 Jefferson Medical College students who graduated in 2011-2013. Students used a peer nomination instrument to identify classmates who had a positive influence on their professional and personal development. At matriculation, these students had completed a survey that included the Jefferson Scale of Empathy and Zuckerman-Kuhlman Personality Questionnaire short form and abridged versions of the Rosenberg Self-Esteem Scale and UCLA Loneliness Scale. In multivariate analyses of variance, the method of contrasted groups was used to compare the personality attributes of students nominated most frequently by their peers as positive influencers (top influencers [top 25% in their class distribution], n = 176) with those of students nominated least frequently (bottom influencers [bottom 25%], n = 171). The top influencers scored significantly higher on empathy, sociability, and activity and significantly lower on loneliness compared with the bottom influencers. However, the effect size estimates of the differences were moderate at best. The research hypotheses were partially confirmed. Positive social influencers appear to possess personality attributes conducive to relationship building, which is an important feature of effective leadership. The findings have implications for identifying and training potential leaders in medicine.

Recently, two experiments were concluded in Hall A at Jefferson Lab which utilized a newly assembled, solid, polarized hydrogen target. The primary components of the target are a new, high cooling power 4He evaporation refrigerator, and a re-purposed, superconducting split-coil magnet. It has been used to polarize protons in irradiated NH3 at a temperature of 1 K and at fields of 2.5 and 5.0 tesla. Maximum polarizations of 55% and 95% were obtained at those fields, respectively. To satisfy the requirements of both experiments, the magnet had to be routinely rotated between angles of 0°, 6°, and 90° with respect to the incident electron beam.

We have constructed and commissioned a double-arm Møller polarimeter for the Hall B beamline at the Thomas Jefferson National Accelerator Facility. The polarimeter measures the longitudinal polarization of the 0.8-4.0 GeV electron beam as it enters the experimental hall. The primary components of the apparatus are a target chamber, a pair of quadrupole magnets, and a pair of lead/scintillating-fiber detectors. The target chamber contains two 20 μm-thick permendur foils tilted at ± 20^o with respect to the beam axis. A target polarization of approximately 8% is produced along the beam direction by a 90 G (nominal) magnetic field generated by a pair of Helmholtz coils. The scattered Møller-electron pairs are directed toward the detectors by the quadrupoles. The quadrupoles are are individually tuned--depending on the beam energy--to center the peak of the Møller asymmetry (θ_c.m.=90^o) onto the fixed detectors. The real-to-accidental coincident-detection rate is better than 200:1. The beam polarization can be measured to a 3% relative statistical precision in less than 30 minutes with a relative systematic uncertainty of less than 5%.

The tsunami that struck South-east Asia on 26 December 2004 left more than 500,000 people in Aceh, Indonesia, homeless and displaced to temporary barracks and other communities. This study examines the associations between prolonged habitation in barracks and the nature of fears reported by school-age children and adolescents. In mid-2007, 30 months after the tsunami, the authors interviewed 155 child and parent dyads. Logistic regression analysis was used to compare the fears reported by children and adolescents living in barracks with those reported by their peers who were living in villages. After adjusting for demographic factors and tsunami exposure, the data reveals that children and adolescents living in barracks were three times more likely than those living in villages to report tsunami-related fears. The study demonstrates that continued residence in barracks 30 months after the tsunami is associated with higher rates of reporting tsunami-related fears, suggesting that barracks habitation has had a significant impact on the psychological experience of children and adolescents since the tsunami. © 2012 The Author(s).

Objective. To measure changes in pharmacy and medical students’ empathy scores after a 40-minute workshop during which students observed and discussed a theatrical performance about the challenges of aging. Methods. First-year pharmacy and medical students (n = 187 and n = 183, respectively) participating in the workshop observed and discussed a 10-minute performance in which students enacted problems and concerns faced by elderly patients. The Jefferson Scale of Empathy (JSE) was administered just prior to the workshop (pretest), immediately afterward (posttest 1), and 7 or 26 days afterward (posttest 2). Results. Empathy increased significantly from pretest to posttest 1 for students of each profession (p <0.01). Improvement in empathy scores declined by the time the JSE was readministered to pharmacy students 7 days later and to medical students 26 days later (posttest 2). Similar patterns of improved and declining empathy were found when the data were analyzed by gender and medical student specialty interest (ie, primary vs non-primary care specialties). Conclusion. Empathy scores increased but were not sustained for both pharmacy and medical students after a brief workshop on aging that required limited personnel resources. PMID:22412208

A drift chamber system consisting of 24 1 m-diameter chambers with both cathode and wire readout (total of 12,672 channels) is operational in Hall D at Jefferson Lab (Virginia). Two cathode strip planes and one wire plane in each chamber register the same avalanche allowing the study of avalanche development, charge induction process, and strip resolution. We demonstrate a method for reconstructing the two-dimensional distribution of the avalanche “center-of-gravity” position around the wire from an 55Fe source with resolutions down to 30 μm. We estimate the azimuthal extent of the avalanche around the wire as a function of the totalmore » charge for an Ar/CO 2 gas mixture. By means of cluster counting using a modified 3 cm-gap chamber, we observe significant space charge effects within the same track, resulting in an extent of the avalanche along the wire.« less

Addressing Physics Grand Challenges Using the Jefferson Lab FEL

The Jefferson Lab Free Electron Laser[1] is the first of the so-called 4^th generation light sources to go operational. Capable of delivering extraordinarily bright, tunable light in ultrafast pulses from THz[2] through infrared to UV, the facility extends the experimental reach of accelerator-based light-sources by many orders of magnitude. This allows new opportunities to study many of the ``Grand Challenges'' recently defined by the Office of Science, Basic Energy Sciences Division, most of which are concerned with understandings of equilibrium and non-equilibrium behavior of materials in physics, chemistry and biology using precise pump and probe techniques. Specifically, in condensed matter physics, the JLab FEL permits new studies which go beyond earlier studies of reductionist behavior to those which examine emergent behavior. Thus, the understanding of high Tc superconductivity, colossal magneto-resistance, and observations of the breakdown of the Born-Oppenheimer approximation, are examples of collective behavior which is now treated theoretically via the concept of quasiparticles. In this presentation we will describe the dual pathways of light source development and physics challenges, and then show how they are combined in experiments that allow new insights to be developed to understand material function. We will illustrate this with details of the evolution of accelerator-based light sources, and with examples of work performed to date. References: [1] Neil et al. Phys. Rev.Letts 84, 662 (2000).

Polarized positrons in Jefferson lab electron ion collider (JLEIC)

2018-05-01

The Jefferson Lab Electron Ion Collider (JLEIC) is designed to provide collisions of electron and ion beams with high luminosity and high polarization to reach new frontier in exploration of nuclear structure. The luminosity, exceeding 1033 cm-2s-1 in a broad range of the center-of-mass (CM) energy and maximum luminosity above 1034 cm-2s-1, is achieved by high-rate collisions of short small-emittance low-charge bunches with proper cooling of the ion beam and synchrotron radiation damping of the electron beam. The polarization of light ion species (p, d, 3He) and electron can be easily preserved, manipulated and maintained by taking advantage of the unique figure-8 shape rings. With a growing physics interest, polarized positron-ion collisions are considered to be carried out in the JLEIC to offer an additional probe to study the substructure of nucleons and nuclei. However, the creation of polarized positrons with sufficient intensity is particularly challenging. We propose a dedicated scheme to generate polarized positrons. Rather than trying to accumulate "hot" positrons after conversion, we will accumulate "cold" electrons before conversion. Charge accumulation additionally provides a novel means to convert high repetition rate (>100 MHz) electron beam from the gun to a low repetition rate (<100 MHz) positron beam for broad applications. In this paper, we will address the scheme, provide preliminary estimated parameters and explain the key areas to reach the desired goal.

Effectiveness of a Coral-Derived Surfacing Material for Reducing Sediment Production on Unpaved Roads, Schoffield Barracks, Oahu, Hawaii

Ziegler, Alan D.; Sutherland, Ross A.

2006-01-01

This study evaluated the effectiveness of two application rates of a coral-derived surfacing material for both traffic and nontraffic road conditions using simulated rainfall (110-120 mm h-1 for 30-90 min) on 0.75-m (wide) × 5.0-m (long) plots of similar slope (roughly 0.1 m m-1). The coral is a locally available material that has been applied to unpaved roads surfaces on Schoffield Barracks, Oahu, Hawaii (USA), where this experiment was conducted. The simulations show that compared with a bare control plot, the coral-based surface application rates of 80 and 160 kg m-2 (equivalent to only 10- and 20-mm thicknesses) reduced road sediment production by 75% and 95%, respectively, for nontraffic conditions. However, after two passes of the research vehicle during wet conditions, sediment production rates for the two coral treatments were not significantly different from those on the bare road plots. The overall effectiveness of the coral-derived surfacing material is unsatisfactory, primarily because the on-road surface thickness associated with the application rates tested was too small. These rates were selected to bracket those applied to training roads in the study area. Furthermore, the composition of the coral-based material does not facilitate the development of a sealed, erosion-resistant surface. When applied at the low rates tested, the coral material breaks down under normal traffic conditions, thereby losing its ability to counter shearing forces exerted by overland flow on long hillslopes where erosion measures are most needed. These simulations, combined with observations on roads in the study area, indicate that this material is not an appropriate road surfacing material for the site—at least for the low application rates examined. These results are preliminary; extended testing of higher applications rates at the hillslope scale under natural climate and traffic conditions is needed to better judge the effectiveness of this material over time.

Physician empathy is a core attribute in medical professionals, giving better patient outcomes. Medical school is an opportune time for building empathetic foundations. This study explores empathy change and focuses on contributory factors. We conducted a cross-sectional study involving 881 students (63%) from Years 1 to 5 in a Singaporean medical school using the Jefferson Scale of Physician Empathy-Student version (JSPE-S) and a questionnaire investigating the relationship between reported and novel personal-social empathy determinants. Empathy declined significantly between preclinical and clinical years. Female and medical specialty interest respondents had higher scores than their counterparts. Despite strong internal consistency, factor analysis suggested that the JSPE model is not a perfect fit. Year 1 students had highest Perspective Taking scores and Year 2 students had highest Compassionate Care scores. High workload and inappropriate learning environments were the most relevant stressors. Time spent with family, arts, and community service correlated with higher empathy scores, whilst time spent with significant others and individual leisure correlated with lower scores. Thematic analysis revealed that the most common self-reported determinants were exposure to activity (community service) or socialisation, personal and family-related event as well as environment (high work-load). While the empathy construct in multicultural Singapore is congruent with a Western model, important differences remain. A more subtle understanding of the heterogeneity of the medical student experience is important. A greater breadth of determinants of empathy, such as engagement in arts-related activities should be considered.

Introduction Empathy among medical practitioners has been shown to affect patient care and outcomes. Factors such as stress and depression are known to have a negative impact on medical student empathy. Approaches such as mindfulness, meditation, and other mind-body techniques can enhance empathy and reverse burnout symptoms. In the present study, we evaluated impact of Mind Body Medicine (MBM) course on perceived stress and empathy on first-year medical students. Methods Thirteen first-year medical students in total self-selected into MBM (experimental) and seven non-MBM (control) groups completed a prospective, pre- and post-test analysis, using the Jefferson Scale of Physician Empathy - Students (JSPE-S), Perceived Stress Scale (PSS), and Personal Health Questionnaire (PHQ) to evaluate empathy, stress, and depression, respectively. Results Our results showed an increase in stress, as well as a decrease in empathy, in both MBM and non-MBM groups throughout the course of the study. Conclusion Our study demonstrated that the inverse relationship increased stress and decreased empathy among first-year medical students and participation in the MBM course did not attenuate the changes. However, a statistically significant rise in the depression score in the non-MBM group was not observed in the MBM group.

The education and medical practice of Dr. James McCune Smith (1813-1865), first black American to hold a medical degree.

James McCune Smith (1813-1865)--first black American to obtain a medical degree, prominent abolitionist and suffragist, compassionate physician, prolific writer, and public intellectual--has been relatively neglected by historians of medicine. No biography of Smith exists to this day, though he has been the subject of several essays. Born, in his own words, "the son of a self-emancipated bond-woman," and denied admission to colleges in the United States, his native land, Smith earned medical, master's, and baccalaureate degrees at Glasgow University in Scotland. On his return to New York City in 1837, Smith became the first black physician to publish articles in US medical journals. Smith was broadly involved in the anti-slavery and suffrage movements, contributing to and editing abolitionist newspapers and serving as an officer of many organizations for the improvement of social conditions in the black community. In his scientific writings Smith debunked the racial theories in Thomas Jefferson's Notes on the State of Virginia, refuted phrenology and homeopathy, and responded with a forceful statistical critique to the racially biased US Census of 1840. Frederick Douglass, Gerrit Smith, and John Brown personally collaborated with James McCune Smith in the fight for black freedom. As the learned physician-scholar of the abolition movement, Smith was instrumental in making the overthrow of slavery credible and successful. Images Figure 1 PMID:12911258

To measure mean empathy scores of Pakistani medical students and to explore any association of empathy scores with gender, medical school year and future career choice. Cross-sectional survey. Shifa College of Medicine, Shifa Tameer-e-Millat University, during the academic year 2015-2016. The student version of Jefferson Scale of Physician Empathy (JSPE) was distributed to the students electronically via the student portal. Response that were completed in full were included in the study. Descriptive statistics was used to analyse student demographic data. The student score on the JSPE was reported as the mean (out of 7) of each item. Independent samples t-test was employed to check the significant differences between genders. Empathy score with advancing year of study was investigated using ANOVA. ANOVA with post-hoc Tukey's test was used to study the relationship between career choice and empathy score. The response rate was 70.94%. The mean score was 4.51 ±0.69. Females obtained greater, but statistically insignificant (p=0.08) empathy score (4.58) as compared to the male students (4.45). No statistically significant difference was seen between scores on the survey across the five academic years (F=0.88, p=0.47). Students who selected medicine and allied as career choice showed a significantly higher empathy score than those who opted for surgery. The internal consistency reliability (Cronbach's alpha) was 0.78. There were low levels of empathy in Pakistani medical students. Students with interest in medicine and allied showed higher empathy scores compared to surgical or technical specialties. No association of empathy scores with gender and medical school year was observed.

Research suggests that medical student empathy erodes during undergraduate medical education. The authors evaluated the Jefferson Scale of Physician Empathy Medical Student Version (JSPE-MS) scores of two consecutive medical school classes to assess the impact of an educational intervention on the preservation of empathy. The authors conducted a before-and-after study of 209 Robert Wood Johnson Medical School (RWJMS) students enrolled in the classes of 2009 and 2010. Students' clerkships included a mandatory, longitudinal "Humanism and Professionalism" (H&P) component, which included blogging about clerkship experiences, debriefing after significant events, and discussing journal articles, fiction, and film. Students completed the JSPE-MS during their first and last clerkships. The results showed that (1) contrary to previous studies' findings, third-year students did not show significant decline in empathy as measured by the JSPE-MS (these students, from two consecutive RWJMS classes, experienced the H&P intervention), (2) students selected for the Gold Humanism Honor Society (GHHS) were significantly different from their peers in empathy scores as measured by JSPE-MS, and (3) knowledge of selection for the GHHS seems to positively influence students' JSPE-MS scores. Maintaining empathy during the third year of medical school is possible through educational intervention. A curriculum that includes safe, protected time for third-year students to discuss their reactions to patient care situations during clerkships may have contributed to the preservation of empathy. Programs designed to validate humanism in medicine (such as the GHHS) may reverse the decline in empathy as measured by the JSPE-MS.

Obstetric violence involves a violation of reproductive rights of women during pregnancy, childbirth and postpartum. It has been associated with lack of empathy and emotional discomfort of physicians. To identify the perceptions of obstetric violence and to determine the possible relationship with burnout syndrome. We evaluated 29 physicians whose scope of work relates to obstetrics and gynecology. The evaluation instruments were: a) questionnaire on professional perception that collects demographic information, situations of perceived obstetric violence, major concerns of physicians in their professional work, and includes an scale about level of job satisfaction, b) the Maslach Burnout inventory, and c) Jefferson Scale of Physician Empathy. The most prevalent obstetric violence situations perceived were: medical malpractice and harmful practices (10/29), discrimination (10/29), rude treatment and verbal attacks (11/29). Seventeen participants reported lack of information on obstetric violence and not have tools to cope with this problem. Regarding the burnout syndrome, it was associated with several items of the scale of empathy and with the scale of job satisfaction. This study shows the importance of providing knowledge and tools to deal with obstetric violence and stress management to prevent such situations on medical practices.

The Jefferson Lab 12 GeV Upgrade in Hall B will need CLAS12 detector that requires two superconducting magnets. One is a magnet system consisting of six superconducting trapezoidal racetrack-type coils assembled in a Toroidal configuration (Torus) and the second is an actively shielded solenoidal magnet (Solenoid). Both the torus and solenoid are located in close proximity to one another and are surrounded by sensitive detectors. This paper investigates the electromagnetic interactions between the two systems during normal operation as well as during various fault scenarios as part of a Risk Assessment and Mitigation (RAM).

A Quantitative Study of Empathy in Pakistani Medical Students: A Multicentered Approach.

To examine the empathy level of undergraduate medical students in Pakistan. Three hypotheses are developed based on the literature review. (1) Female medical students have a higher level of empathy than do male students. (2) Empathy scores vary during the medical school years in Pakistani students. (3) Medical students interested in people-oriented specialties would score higher than the students interested in technology-oriented specialties. This is a quantitative inquiry approach using a cross-sectional design of 1453 students from 8 Pakistani medical schools, both private and state. The sample consists of 41.1% (n = 597) male students and 58.9% (n = 856) female students. Empirical data are collected using the Jefferson Scale of Physician Empathy (JSPE), a well-validated self-administered questionnaire. The mean empathy score among students is 4.77 with a standard deviation of 0.72. The results show that there is no statistically significant association between the empathy scores and gender, t(1342.36) = -0.053, P = .95). There is a statistically significant difference between the empathy scores and the years of medical school, F(14, 1448) = 4.95, P = .01. Concerning the specialty interests, there is no statistically significant difference between the empathy score and specialty interests. The findings of this study showed that in Western countries, medical students performed better than Pakistani medical students on the empathy scale. This finding has important implications for Pakistani medical educators to improve the interpersonal skills of medical students in the context of patient care. Inconsistent with our expectations and experiences, our findings do not support that female medical students scored better than their male counterparts on the empathy scale. Because of the nature of a cross-sectional study, it is impossible to argue the decline of empathy during medical school training.

We present a search for ten baryon number violating decay modes of Λ hyperons using the CLAS detector at Jefferson Laboratory. Nine of these decay modes result in a single meson and single lepton in the final state (Λ →m ℓ) and conserve either the sum or the difference of baryon and lepton number (B ±L ). The tenth decay mode (Λ →p ¯ π+ ) represents a difference in baryon number of two units and no difference in lepton number. We observe no significant signal and set upper limits on the branching fractions of these reactions in the range (4 - 200 )×10-7 at the 90% confidence level.

Objectives To examine the relationship between stress, social support, and empathy among medical students. Methods We evaluated the relationships between stress and empathy, and social support and empathy among medical students. The respondents completed a question-naire including demographic information, the Jefferson Scale of Empathy, the Perceived Stress Scale, and the Multidimensional Scale of Perceived Social Support. Corre-lation and linear regression analyses were conducted, along with sub-analyses according to gender, admission system, and study year. Results In total, 2,692 questionnaires were analysed. Empathy and social support positively correlated, and empathy and stress negatively correlated. Similar correla-tion patterns were detected in the sub-analyses; the correla-tion between empathy and stress among female students was negligible. In the regression model, stress and social support predicted empathy among all the samples. In the sub-analysis, stress was not a significant predictor among female and first-year students. Conclusions Stress and social support were significant predictors of empathy among all the students. Medical educators should provide means to foster resilience against stress or stress alleviation, and to ameliorate social support, so as to increase or maintain empathy in the long term. Furthermore, stress management should be emphasised, particularly among female and first-year students. PMID:26342190

Purpose: Physician empathy is a core attribute in medical professionals, giving better patient outcomes. Medical school is an opportune time for building empathetic foundations. This study explores empathy change and focuses on contributory factors. Methods: We conducted a cross-sectional study involving 881 students (63%) from Years 1 to 5 in a Singaporean medical school using the Jefferson Scale of Physician Empathy-Student version (JSPE-S) and a questionnaire investigating the relationship between reported and novel personal-social empathy determinants. Results: Empathy declined significantly between preclinical and clinical years. Female and medical specialty interest respondents had higher scores than their counterparts. Despite strong internal consistency, factor analysis suggested that the JSPE model is not a perfect fit. Year 1 students had highest Perspective Taking scores and Year 2 students had highest Compassionate Care scores. High workload and inappropriate learning environments were the most relevant stressors. Time spent with family, arts, and community service correlated with higher empathy scores, whilst time spent with significant others and individual leisure correlated with lower scores. Thematic analysis revealed that the most common self-reported determinants were exposure to activity (community service) or socialisation, personal and family-related event as well as environment (high work-load). Conclusion: While the empathy construct in multicultural Singapore is congruent with a Western model, important differences remain. A more subtle understanding of the heterogeneity of the medical student experience is important. A greater breadth of determinants of empathy, such as engagement in arts-related activities should be considered. PMID:26838570

Performance Testing of Jefferson Lab 12 GeV Helium Screw Compressors

Oil injected screw compressors have essentially superseded all other types of compressors in modern helium refrigeration systems due to their large displacement capacity, reliability, minimal vibration, and capability of handling helium's high heat of compression. At the present state of compressor system designs for helium refrigeration systems, typically two-thirds of the lost input power is due to the compression system. It is important to understand the isothermal and volumetric efficiencies of these machines to help properly design the compression system to match the refrigeration process. It is also important to identify those primary compressor skid exergetic loss mechanisms which maymore » be reduced, thereby offering the possibility of significantly reducing the input power to helium refrigeration processes which are extremely energy intensive. This paper summarizes the results collected during the commissioning of the new compressor system for Jefferson Lab's (JLab's) 12 GeV upgrade. The compressor skid packages were designed by JLab and built to print by industry. They incorporate a number of modifications not typical of helium screw compressor packages and most importantly allow a very wide range of operation so that JLab's patented Floating Pressure Process can be fully utilized. This paper also summarizes key features of the skid design that allow this process and facilitate the maintenance and reliability of these helium compressor systems.« less

The effect of visual arts interventions on development of empathy has not been quantitatively investigated. A study was conducted on the effect of a visual arts-based program on the scores of the Jefferson Scale for Physician Empathy (JSPE). A total of 110 clerks (n = 92) and first-year postgraduate residents (PGY1s) (n = 18) participating in the program were recruited into this study. The 4-hr program covered the subjects of learning to interpret paintings, interpreting paintings relating to medicine, illness and human suffering, the related-topics of humanitarianism and the other humanities fields and values and meaning. The JSPE was completed at the beginning (pretest) and the end (posttest) of the program. There was no significant difference between the pretest and posttest JSPE scores. The average of the scores for the pretest was lower in the subgroup of PGY1s than the subgroup of clerks (p = 0.0358). An increased but not significantly mean posttest JESPE score was noted for the subgroup of PGY1s. Neither the females nor the males had higher posttest JSPE scores than the pretest scores. Although using a structured visual arts-based program as an intervention may be useful to enhance medical students' empathy, our results failed to show a positive effect on the JSPE Scores for a group of clerks and PGY1s. This suggests that further experimental studies are needed if quantitative evaluation of the effectiveness of visual-arts based programs on empathy is to be investigated.

HDice, Highly-Polarized Low-Background Frozen-Spin HD Targets for CLAS experiments at Jefferson Lab

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

Wei, Xiangdong; Bass, Christopher; D'Angelo, Annalisa

2012-12-01

Large, portable frozen-spin HD (Deuterium-Hydride) targets have been developed for studying nucleon spin properties with low backgrounds. Protons and Deuterons in HD are polarized at low temperatures (~10mK) inside a vertical dilution refrigerator (Oxford Kelvinox-1000) containing a high magnetic field (up to 17T). The targets reach a frozen-spin state within a few months, after which they can be cold transferred to an In-Beam Cryostat (IBC). The IBC, a thin-walled dilution refrigerator operating either horizontally or vertically, is use with quasi-4{pi} detector systems in open geometries with minimal energy loss for exiting reaction products in nucleon structure experiments. The first applicationmore » of this advanced target system has been used for Spin Sum Rule experiments at the LEGS facility in Brookhaven National Laboratory.

A new gas Cherenkov detector is under construction for the upcoming SuperBigBite spectrometer research program in Hall A at Jefferson Lab. The existing BigBite spectrometer is being upgraded to handle expected increases in event rate and background rate due to the increased luminosity required for the experimental program. The detector will primarily be used to separate good electron events from significant pion and electromagnetic contamination. In contrast to typical gas Cherenkov detectors that use large-diameter photomultiplier tubes and charge integrating ADCs, this detector uses an array of 510 small-diameter tubes that are more than 25x less sensitive to background. Cherenkov radiation clusters will be identified in this array using fast TDCs and a narrow timing window relative to typical ADC gates. In addition, a new FPGA-based DAQ system is being tested to provide a PID trigger using real-time cluster finding. Details of the detector and current status of the project will be presented.

2016-02-01

Beam-line equipment was upgraded for experiment E08-027 (g2p) in Hall A at Jefferson Lab. Two beam position monitors (BPMs) were necessary to measure the beam position and angle at the target. A new BPM receiver was designed and built to handle the low beam currents (50-100 nA) used for this experiment. Two new super-harps were installed for calibrating the BPMs. In addition to the existing fast raster system, a slow raster system was installed. Before and during the experiment, these new devices were tested and debugged, and their performance was also evaluated. In order to achieve the required accuracy (1-2 mm in position and 1-2 mrad in angle at the target location), the data of the BPMs and harps were carefully analyzed, as well as reconstructing the beam position and angle event by event at the target location. The calculated beam position will be used in the data analysis to accurately determine the kinematics for each event.

Here we present preliminary results for the gain performance of commercially available 3- mum and 6- mum pore-size single-anode microchannel-plate photomultipliers (MCP PMTs) in magnetic fields up to 5 T and for various orientations of the sensor relative to the field direction. The measurements were performed at Thomas Jefferson National Accelerator Facility in Newport News, VA. Our results show that smaller-pore-size PMTs have better gain performance in magnetic fields. At various angles, the shape of the gain dependence on the strength of the magnetic field strongly depends on the type of the sensor. Also, for each sensor, the azimuthal dependencemore » is strongly correlated with the polar angle. Overall, the sensors exhibit a reasonable performance up to 2 T, although that upper limit depends on the sensor, the applied high voltage, and the orientation of the sensor relative to the field. To optimize the operational and design parameters of MCP PMTs for performance in high magnetic fields, further measurements and simulation studies will be pursued. Furthermore, our studies are part of an R&D for development of a Detector of Internally Reflected Cherenkov Light for the central detector of a future U.S. Electron Ion Collider.« less

Simulations of a FIR Oscillator with Large Slippage parameter at Jefferson Lab for FIR/UV pump-probe experiments

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

Benson, Stephen V.; Campbell, L. T.; McNeil, B.W.T.

We previously proposed a dual FEL configuration on the UV Demo FEL at Jefferson Lab that would allow simultaneous lasing at FIR and UV wavelengths. The FIR source would be an FEL oscillator with a short wiggler providing diffraction-limited pulses with pulse energy exceeding 50 microJoules, using the exhaust beam from a UVFEL as the input electron beam. Since the UV FEL requires very short pulses, the input to the FIR FEL is extremely short compared to a slippage length and the usual Slowly Varying Envelope Approximation (SVEA) does not apply. We use a non-SVEA code to simulate this systemmore » both with a small energy spread (UV laser off) and with large energy spread (UV laser on).« less

Nine of these decay modes result in a single meson and single lepton in the final state (Λ → mΙ) and conserve either the sum or the difference of baryon and lepton number (Β ± L). The tenth decay mode (Λ → p¯π +) represents a difference in baryon number of two units and no difference in lepton number.

Spatial analysis of geologic and hydrologic features relating to sinkhole occurrence in Jefferson County, West Virginia

USGS Publications Warehouse

Doctor, Daniel H.; Doctor, Katarina Z.

2012-01-01

In this study the influence of geologic features related to sinkhole susceptibility was analyzed and the results were mapped for the region of Jefferson County, West Virginia. A model of sinkhole density was constructed using Geographically Weighted Regression (GWR) that estimated the relations among discrete geologic or hydrologic features and sinkhole density at each sinkhole location. Nine conditioning factors on sinkhole occurrence were considered as independent variables: distance to faults, fold axes, fracture traces oriented along bedrock strike, fracture traces oriented across bedrock strike, ponds, streams, springs, quarries, and interpolated depth to groundwater. GWR model parameter estimates for each variable were evaluated for significance, and the results were mapped. The results provide visual insight into the influence of these variables on localized sinkhole density, and can be used to provide an objective means of weighting conditioning factors in models of sinkhole susceptibility or hazard risk.

2015-06-01

Because most medical schools in the United States and Canada require no formal ophthalmology training, the authors queried medical student and ophthalmic patients to compare their perceptions of the quality of life (QOL) associated with vision loss. Cross-sectional comparative study of consecutive medical students and patients with vision loss using a validated, reliable, time trade-off utility instrument. Consecutive Jefferson Medical College medical students (cohort 1: 145 second-year student; cohort 2: 112 third-year/fourth-year students) and 283 patients with vision loss (patient cohort). Time trade-off vision utilities with anchors of 0.0 (death) to 1.0 (normal vision permanently) were used to quantify the QOL associated with vision loss. Students were asked to assume they had: (i) mild vision loss (20/40 to 20/50 vision in the better-seeing eye), (ii) legal blindness (20/200 in the better-seeing eye), and (iii) absolute blindness (no light perception bilaterally). Mean utilities for cohort 1/cohort 2 were 0.96/0.95 (p = 0.20) for mild vision loss, 0.88/0.84 for legal blindness (p = 0.009), and 0.80/0.67 (p < 0.0001) for absolute blindness. Medical student/patient mean utilities were 0.96/0.79 (p < 0.0001) for mild vision loss, 0.85/0.62 for legal blindness (p < 0.0001), and 0.74/0.26 (p < 0.0001) for absolute blindness. Overall, medical students underestimated the QOL associated with vision loss referent to patients with vision loss by 153%-425%. Medical students dramatically underestimated the impact of vision loss on patient QOL. Clinical training slightly improved medical student perceptions. Trivialization of vision loss could result in systemic health harm, less ophthalmic research dollars, loss of the finest medical students entering ophthalmology, and overall adverse financial effects for the field.

Impostor syndrome and burnout among American medical students: a pilot study

PubMed Central

Sobin, Lindsay B.; Koester, Lindsey A.; Harris, Tucker M.

2016-01-01

Objectives To describe levels of burnout and impostor syndrome (IS) in medical students, and to recognize demographic differences in those experiencing burnout and IS. Methods Research participants included 2,612 medical students who entered Jefferson Medical College between 2002 and 2012. This sample was divided into two groups: Matriculants between 2002 and 2007 (n=1,380) and between 2008 and 2012 (n=1,232). Data for 2002-2007 matriculants were subjected to EFA (principal component factor extraction), and data for matriculants of 2008-2012 were used for CFA (structural equation modeling, and root mean square error for approximation). Results One hundred and thirty-eight students completed the questionnaire. Female gender was significantly associated with IS (χ2(3)=10.6, p=0.004) with more than double the percentage of females displaying IS than their male counterparts (49.4% of females versus 23.7% of males). IS was significantly associated with the burnout components of exhaustion (χ2 (2)=5.9, p=0.045), cynicism (χ2(2)=9.4, p=0.004), emotional exhaustion (χ2(2)=8.0, p=0.018), and depersonalization (χ2 (2)=10.3, p=0.006). The fourth year of medical school was significantly associated with IS (χ2(3)=10.5, p=0.015). Conclusions Almost a quarter of male medical students and nearly half of female students experience IS and IS was found to be significantly associated with burnout indices. Given the high psychological morbidity of these conditions, this association cannot be ignored. It behooves us to reconsider facets of medical education (i.e. shame-based learning and overall teaching style) and optimize the medical learning environment. PMID:27802178

Associations between Medical Student Empathy and Personality: A Multi-Institutional Study

2014-01-01

Background More empathetic physicians are more likely to achieve higher patient satisfaction, adherence to treatments, and health outcomes. In the context of medical education, it is thus important to understand how personality might condition the empathetic development of medical students. Single institutional evidence shows associations between students' personality and empathy. This multi-institutional study aimed to assess such associations across institutions, looking for personality differences between students with high empathy and low empathy levels. Methods Participants were 472 students from three medical schools in Portugal. They completed validated adaptations to Portuguese of self-report measures of the NEO-Five Factor Inventory(NEO-FFI) and the Jefferson Scale of Physician Empathy(JSPE-spv). Students were categorized into two groups: “Bottom” (low empathy, N = 165) and “Top” (high empathy, N = 169) according to their empathy JSPE-spv total score terciles. Correlation analysis, binary logistic regression analysis and ROC curve analysis were conducted. Results A regression model with gender, age and university had a predictive power (pseudo R2) for belonging to the top or bottom group of 6.4%. The addition of personality dimensions improved the predictive power to 16.8%. Openness to experience and Agreeableness were important to predict top or bottom empathy scores when gender, age and university were considered.” Based on the considered predictors the model correctly classified 69.3% of all students. Conclusions The present multi-institutional cross-sectional study in Portugal revealed across-school associations between the Big5 dimensions Agreeableness and Openness to experience and the empathy of medical students and that personality made a significant contribution to identify the more empathic students. Therefore, medical schools may need to pay attention to the personality of medical students to understand how to enhance the

The new fit results for the multipoles are compared with predictions not taking into account the new data. The mutual agreement is improved considerably but still far from being perfect.

Kang, Hoyoung

2014-08-01

The spin structure of the proton has been investigated in the high Bjorken x and low momentum transfer Q 2 region. We used Jefferson Lab's polarized electron beam, a polarized target, and a spectrometer to get both the parallel and perpendicular spin asymmetries Apar and Aperp. These asymmetries produced the physics asymmetries A_1 and A_2 and spin structure functions g_1 and g_2. We found Q 2 dependences of the asymmetries at resonance region and higher-twist effects. Our result increases the available data on the proton spin structure, especially at resonance region with low Q 2. Moreover, A_2 and g_2 datamore » show clear Q 2 evolution, comparing with RSS and SANE-BETA. Negative resonance in A_2 data needs to be examined by theory. It can be an indication of very negative transverse-longitudinal interference contribution at W ~ 1.3 GeV. Higher twist effect appears at the low Q 2 of 1.9 GeV 2, although it is less significant than lower Q 2 data of RSS. Twist03 matrix element d_2 was calculated using our asymmetry fits evaluation at Q 2 – 1.9 GeV 2. D-bar_2 = -0.0087±0.0014 was obtained by integrating 0.47 ≤ x ≤ 0.87.« less

Dynamically polarized target for the g p 2 and G p E experiments at Jefferson Lab

Pierce, J.; Maxwell, J.; Badman, T.; ...

2013-12-16

We describe a dynamically polarized target that has been utilized for two electron scattering experiments in Hall A at Jefferson Lab. The primary components of the target are a new, high cooling power 4 He evaporation refrigerator, and a re-purposed, superconducting split-coil magnet. It has been used to polarize protons in irradiated NH 3 at a temperature of 1 K and at fields of 2.5 and 5.0 Tesla. The performance of the target material in the electron beam under these conditions will be discussed. The maximum polarizations of 28% and 95% were obtained at those fields, respectively. To satisfy themore » requirements of both experiments, the magnet had to be routinely rotated between angles of 0, 6, and 90 degrees with respect to the incident electron beam. This was accomplished using a new rotating vacuum seal which permits rotations to be performed in only a few minutes.« less

Beam position reconstruction for the g2p experiment in Hall A at Jefferson Lab

Zhu, Pengjia; Allada, Kalyan; Allison, Trent

2015-11-03

Beam-line equipment was upgraded for experiment E08-027 (g2p) in Hall A at Jefferson Lab. Two beam position monitors (BPMs) were necessary to measure the beam position and angle at the target. A new BPM receiver was designed and built to handle the low beam currents (50-100 nA) used for this experiment. Two new super-harps were installed for calibrating the BPMs. In addition to the existing fast raster system, a slow raster system was installed. We found that before and during the experiment, these new devices were tested and debugged, and their performance was also evaluated. In order to achieve themore » required accuracy (1-2 mm in position and 1-2 mrad in angle at the target location), the data of the BPMs and harps were carefully analyzed, as well as reconstructing the beam position and angle event by event at the target location. Finally, the calculated beam position will be used in the data analysis to accurately determine the kinematics for each event.« less

Dudek, Jozef; Essig, Rouven; Kumar, Krishna

2012-08-01

We are at the dawn of a new era in the study of hadronic nuclear physics. The non-Abelian nature of Quantum Chromodynamics (QCD) and the resulting strong coupling at low energies represent a significant challenge to nuclear and particle physicists. The last decade has seen the development of new theoretical and experimental tools to quantitatively study the nature of confinement and the structure of hadrons comprised of light quarks and gluons. Together these will allow both the spectrum and the structure of hadrons to be elucidated in unprecedented detail. Exotic mesons that result from excitation of the gluon field willmore » be explored. Multidimensional images of hadrons with great promise to reveal the dynamics of the key underlying degrees of freedom will be produced. In particular, these multidimensional distributions open a new window on the elusive spin content of the nucleon through observables that are directly related to the orbital angular momenta of quarks and gluons. Moreover, computational techniques in Lattice QCD now promise to provide insightful and quantitative predictions that can be meaningfully confronted with, and elucidated by, forthcoming experimental data. In addition, the development of extremely high intensity, highly polarized and extraordinarily stable beams of electrons provides innovative opportunities for probing (and extending) the Standard Model, both through parity violation studies and searches for new particles. Thus the 12 GeV upgrade of the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab will enable a new experimental program with substantial discovery potential to address these and other important topics in nuclear, hadronic and electroweak physics.« less

Fermi National Accelerator Laboratory (Fermilab) fabricated the torus magnet coils for the 12-GeV Hall B upgrade at Jefferson Lab (JLab). The production consisted of six large superconducting coils for the magnet and two spare coils. The toroidal field coils are approximately 2 m × 4 m × 5 cm thick. Each of these coils consists of two layers, each of which has 117 turns of copper-stabilized superconducting cable, which will be conduction cooled by supercritical helium. Due to the size of the coils and their unique geometry, Fermilab designed and fabricated specialized tooling and, together with JLab, developed unique manufacturingmore » techniques for each stage of the coil construction.

Uhrich, Mark A.

2010-01-01

A debris flow and sediment torrent occurred on the flanks of Mt Jefferson in Oregon on November 6, 2006, inundating 150 acres of forest. The massive debris flow was triggered by a rock and snow avalanche from the Milk Creek glaciers and snowfields during the early onset of an intense storm originating near the Hawaiian Islands. The debris flow consisted of a heavy conglomerate of large boulders, cobbles, and coarse-grained sediment that was deposited at depths of up to 15 ft and within 3 mi of the glaciers, and a viscous slurry that deposited finer-grained sediments at depths of 0.5 to 3 ft. The muddy slurry coated standing trees within the lower reaches of Milk Creek as it moved downslope.

Role of a Semiotics-Based Curriculum in Empathy Enhancement: A Longitudinal Study in Three Dominican Medical Schools.

PubMed

San-Martín, Montserrat; Delgado-Bolton, Roberto; Vivanco, Luis

2017-01-01

Background: Empathy in the context of patient care is defined as a predominantly cognitive attribute that involves an understanding of the patient's experiences, concerns, and perspectives, combined with a capacity to communicate this understanding and an intention to help. In medical education, it is recognized that empathy can be improved by interventional approaches. In this sense, a semiotic-based curriculum could be an important didactic tool for improving medical empathy. The main purpose of this study was to determine if in medical schools where a semiotic-based curriculum is offered, the empathetic orientation of medical students improves as a consequence of the acquisition and development of students' communication skills that are required in clinician-patient encounters. Design: This quasi-experimental study was conducted in three medical schools of the Dominican Republic that offer three different medical curricula: (i) a theoretical and practical semiotic-based curriculum; (ii) a theoretical semiotic-based curriculum; and (iii) a curriculum without semiotic courses. The Jefferson scale of empathy was administered in two different moments to students enrolled in pre-clinical cycles of those institutions. Data was subjected to comparative statistical analysis and logistic regression analysis. Results: The study included 165 students (55 male and 110 female). Comparison analysis showed statistically significant differences in the development of empathy among groups ( p < 0.001). Logistic regression confirmed that gender, age, and a semiotic-based curriculum contributed toward the enhancement of empathy. Conclusion: These findings demonstrate the importance of medical semiotics as a didactic teaching method for improving beginners' empathetic orientation in patients' care.

Neumann, Melanie; Scheffer, Christian; Tauschel, Diethard; Lutz, Gabriele; Wirtz, Markus; Edelhäuser, Friedrich

2012-01-01

The present study gives a brief introduction into 1. the definition of physician empathy (PE) and 2. its influence on patients' health outcomes. Furthermore 3. we present assessment instruments to measure PE from the perspective of the patient and medical student. The latter topic will be explored in detail as we conducted a pilot study on the German versions of two self-assessment instruments of empathy, which are mostly used in medical education research, namely the "Jefferson Scale of Physician Empathy, Student Version" (JSPE-S) and the "Interpersonal Reactivity Index" (IRI). We first present an overview of the current empirical and theoretical literature on the definition and outcome-relevance of PE. Additionally, we conducted basic psychometric analyses of the German versions of the JSPE-S and the IRI. Data for this analyses is based on a cross-sectional pilot-survey in N=44 medical students and N=63 students of other disciplines from the University of Cologne. PE includes the understanding of the patient as well as verbal and non-verbal communication, which should result in a helpful therapeutic action of the physician. Patients' health outcomes in different healthcare settings can be improved considerably from a high quality empathic encounter with their clinician. Basic psychometric results of the German JSPE-S and IRI measures show first promising results. PE as an essential and outcome-relevant element in the patient-physician relationship requires more consideration in the education of medical students and, thus, in medical education research. The German versions of the JSPE-S and IRI measures seem to be promising means to evaluate these education aims and to conduct medical education research on empathy.

Studies Of Coherent Synchrotron Radiation And Longitudinal Space Charge In The Jefferson Lab FEL Driver

Tennant, Christopher D.; Douglas, David R.; Li, Rui

2014-12-01

The Jefferson Laboratory IR FEL Driver provides an ideal test bed for studying a variety of beam dynamical effects. Recent studies focused on characterizing the impact of coherent synchrotron radiation (CSR) with the goal of benchmarking measurements with simulation. Following measurements to characterize the beam, we quantitatively characterized energy extraction via CSR by measuring beam position at a dispersed location as a function of bunch compression. In addition to operating with the beam on the rising part of the linac RF waveform, measurements were also made while accelerating on the falling part. For each, the full compression point was movedmore » along the backleg of the machine and the response of the beam (distribution, extracted energy) measured. Initial results of start-to-end simulations using a 1D CSR algorithm show remarkably good agreement with measurements. A subsequent experiment established lasing with the beam accelerated on the falling side of the RF waveform in conjunction with positive momentum compaction (R56) to compress the bunch. The success of this experiment motivated the design of a modified CEBAF-style arc with control of CSR and microbunching effects.« less

Organized health service in Bosnia and Herzegovina practically started by the treatment of the sick in the Hadji Sinan's Tekke that was founded in 1768. Before that, the civilian population had been mainly treated in their homes, while the army were treated in barracks or hired hans (inns). As late as the nineteenth century, health care was provided by quack doctors, treating physicians or surgeons and barbers, who were trained, beside the circumcision of male children, for tooth extraction, broken bone setting, and sometimes even for performing minor surgical operations (a specially trained barber called djerah). The first trained medical personnel were the Franciscans and Jews, who studied at the Universities of Italy, Austria, Hungary etc. The first Muslim trained physicians studied at the Medical Faculty in Istanbul. The first ones were: Dr. Mehmed Serbić and Dr. Zarif Skender, while the first Bosnian graduate in pharmacy was Jakov Sumbul. In Sarajevo and Bosnia and Herzegovina worked many a doctor who came from abroad. The majority of them converted to Islam and worked in the barracks, and later on in the Turkish Military Hospital when it was founded in Sarajevo. All of them played an important role in the prevention and treatment of the most frequent mass infectious and non-infectious diseases that were raging among the population--plague, cholera, syphilis, leprosy, tuberculosis, fungoid diseases etc.

Stroupe, Nancy; McClure, Leslie A.; Wheeler, Lani; Gerald, Lynn B.

2012-01-01

Objectives This paper documents individual asthma action plan presence and quick relief medication (albuterol) availability for elementary students enrolled in five Alabama school systems. Patients and Methods Data were obtained during baseline data collection (fall 2005) of a school-based supervised asthma medication trial. All students attended 1 of 36 participating elementary schools across five school systems in Jefferson County, Alabama. In addition, they had to have physician-diagnosed asthma requiring daily controller medication. Each school system had its own superintendent and elected school board. Asthma action plan presence and albuterol availability was confirmed by study personnel. Asthma action plans had to contain daily and acute asthma management instructions. Predictors of asthma action plan presence and albuterol availability were also investigated. Associations between albuterol availability and self-reported characteristics including health care utilization prior to study enrollment and outcomes during the study baseline period were also investigated. Results Enrolled students had a mean (SD) age of 11.0 (2.1) years, 91% were African American, and 79% had moderate persistent asthma. No student had a complete asthma action plan on file and only 14% had albuterol physically available at school. Albuterol availability was not predicted by gender, race, insurance status, second-hand smoke exposure, need for pre-exercise albuterol, asthma severity, or self-reported health care utilization prior to study enrollment. Albuterol availability did not predict school absences, red/yellow peak flow recordings, or medication adherence during the study's baseline period. Conclusion Despite policies permitting students to possess albuterol, few elementary students across five independent school systems in Alabama actually had it readily available at school.

Utilizing the ubiquitous personal computer as a platform, and Integrated Services Digital Network (ISDN) communications, cost effective medical information access and consultation can be provided for physicians at geographically remote sites. Two modes of access are provided: information retrieval via the Internet, and medical consultation video conferencing. Internet access provides general medical information such as current treatment options, literature citations, and active clinical trials. During video consultations, radiographic and pathology images, and medical text reports (e.g., history and physical, pathology, radiology, clinical laboratory reports), may be viewed and simultaneously annotated by either video conference participant. Both information access modes have been employed by physicians at community hospitals which are members of the Jefferson Cancer Network, and oncologists at Thomas Jefferson University Hospital. This project has demonstrated the potential cost effectiveness and benefits of this technology. Images Figure 1 Figure 2 Figure 3 PMID:8563397

To determine whether performance in any of the Health Professions Admissions Test (HPAT) sections, most specifically the interpersonal understanding section, correlates with self-reported empathy levels in medical students. The study was conducted in University College Cork, Ireland. 290 students participated in the study. Matching HPAT scores were available for 263 students. All male and female undergraduate students were invited to participate. Postgraduate and international students were excluded. Primary measures: HPAT-Ireland and Jefferson Scale of Physician Empathy (JSE) scores were compared including subsection analysis. Secondary measures: comparisons were made between groups such as gender and year of programme. A total of 290 students participated. Males scored significantly higher than females for total HPAT-Ireland (U=7329, z=-2.04, p<0.05), HPAT-Ireland section 1 (U=5382, z=-5.21, p<0.001) and section 3 scores (U=6833, z=-2.85, p<0.01). In contrast, females scored significantly higher than males on HPAT-Ireland section 2 (U=5844, z=-4.46, p<0.001). Females demonstrated significantly higher total JSE scores relative to males (mean score ± SEM: 113.33±1.05 vs 109.21±0.95; U=8450, z=-2.83, p<0.01). No significant association was observed between JSE scores and any of the HPAT-Ireland measures (all p>0.05). There was no effect of programme year on JSE scores (all p>0.05). The introduction of the HPAT-Ireland test was partly designed to identify students with strong interpersonal skills. A significant finding of this study is that JSE values did not correlate with HPAT-Ireland scores. This study suggests no clear link between scores on a selection test, the HPAT-Ireland, which is designed to assess several skill domains including interpersonal skills, and scores on a psychometric measure of empathy, at any point during medical education. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Beam Diagnostics of the Compton Scattering Chamber in Jefferson Lab's Hall C

NASA Astrophysics Data System (ADS)

Faulkner, Adam; I&C Group Collaboration

2013-10-01

Upcoming experimental runs in Hall C will utilize Compton scattering, involving the construction and installation of a rectangular beam enclosure. Conventional cylindrical stripline-style Beam Position Monitors (BPMs) are not appropriate due to their form factor; therefore to facilitate measurement of position, button-style BPMs are being considered due to the ease of placement within the new beam enclosure. Button BPM experience is limited at JLAB, so preliminary measurements are needed to characterize the field response, and guide the development of appropriate algorithms for the Analog to Digital receiver systems. -field mapping is performed using a Goubau Line (G-Line), which employs a surface wave to mimic the electron beam, helping to avoid problems associated with vacuum systems. Potential algorithms include simplistic 1/r modeling (-field mapping), look-up-tables, as well as a potential third order power series fit. In addition, the use of neural networks specifically the multi-layer Perceptron will be examined. The models, sensor field maps, and utility of the neural network will be presented. Next steps include: modification of the control algorithm, as well as to run an in-situ test of the four Button electrodes inside of a mock beam enclosure. The analysis of the field response using Matlab suggests the button BPMs are accurate to within 10 mm, and may be successful for beam diagnostics in Hall C. More testing is necessary to ascertain the limitations of the new electrodes. The National Science Foundation, Old Dominion University, The Department of Energy, and Jefferson Lab.

Physician empathy is associated with improved diabetes outcomes. However, empathy declines throughout medical school training. This study seeks to describe how comics on diabetes affect learning processes for empathy in medical students. All first- or second-year students at a Canadian medical school were invited to provide written reflections on two comics regarding diabetes and participate in a focus group. Responses were analyzed qualitatively for emergent themes. Students completed the Jefferson Scale of Physician Empathy (JSPE) at baseline, after the comic, and after the focus group. Linear mixed model statistical analyses were performed. Thirteen first-year and 12 second-year students participated. Qualitative analysis revealed four themes: 1) Empathy decline and its barriers; 2) Impact of the comic and focus group on knowledge, attitudes and skills; 3) Role of the comic in the curriculum as a reminder tool of the importance of empathy; 4) Comics as an effective medium. Baseline mean JSPE scores were 116.4 (SD 10.5) and trended up to 117.2 (SD 12.5) and 119.6 (SD 15.2) after viewing the comics and participating in the focus groups, respectively (p = 0.08). Animated comics on diabetes are novel methods of reminding students about empathy by highlighting the patient perspective.

Medical specialists face the challenge of maintaining their knowledge and skills and continuing professional development, that is, lifelong learning. Motivation may play an integral role in many of the challenges facing the physician workforce today including maintenance of a high performance. The aim of this study was to determine whether medical specialists show different motivational profiles and if these profiles predict differences in motivation for lifelong learning. An online questionnaire was sent to every medical specialist working in five hospitals in the Netherlands. The questionnaire included the validated Multidimensional Work Motivation Scale and the Jefferson Scale of Physician Lifelong Learning together with background questions like age, gender, and type of hospital. Respondents were grouped into different motivational profiles by using a two-step clustering approach. Four motivational profiles were identified: (1) HAMC profile (for High Autonomous and Moderate Controlled motivation), (2) MAMC profile (for Moderate Autonomous and Moderate Controlled motivation), (3) MALC profile (for Moderate Autonomous and Low Controlled motivation), and (4) HALC profile (for High Autonomous and Low Controlled motivation). Most of the female specialists that work in an academic hospital and specialists with a surgical specialty were represented in the HALC profile. Four motivational profiles were found among medical specialists, differing in gender, experience and type of specialization. The profiles are based on the combination of autonomous motivation (AM) and controlled motivation (CM) in the specialists. The profiles that have a high score on autonomous motivation have a positive association with lifelong learning.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

What Matters More About the Interpersonal Reactivity Index and the Jefferson Scale of Empathy? Their Underlying Constructs or Their Relationships With Pertinent Measures of Clinical Competence and Patient Outcomes?

PubMed

Hojat, Mohammadreza; Gonnella, Joseph S

2017-06-01

In their study published in this issue of Academic Medicine, Costa and colleagues confirmed the underlying constructs of the Interpersonal Reactivity Index (IRI) and the Jefferson Scale of Empathy (JSE) in medical students. The authors of this Commentary propose that in comparing two instruments that both purport to measure empathy, researchers or test users must pay close attention to the target populations, the conceptualizations of empathy, and the validity evidence in relation to pertinent criterion measures. The Commentary's authors draw attention to the fact that the IRI was developed for administration to the general population, whereas the JSE was developed specifically for administration to students and practitioners of health professions. Also, the author of the IRI conceptualized empathy as a combination of cognitive and emotional attributes, whereas the authors of the JSE defined empathy as a predominantly cognitive attribute. These differences are reflected in the content of the items, which determines the underlying constructs of the two instruments. The Commentary authors suggest that any empathy-measuring instrument in the context of health professions education and patient care requires the crucial evidence of significant relationships with indicators of clinical competence and positive patient outcomes. Such validity evidence is readily available for the JSE, and the Commentary authors recommend that researchers make efforts to provide pertinent validity support for any other instrument measuring empathy in health professionals-in-training and in-practice.

Dark Matter Search in a Beam-Dump eXperiment (BDX) at Jefferson Lab

Battaglieri, M.

MeV-GeV dark matter (DM) is theoretically well motivated but remarkably unexplored. This proposal presents the MeV-GeV DM discovery potential for amore » $$\\sim$$1 m$^3$ segmented CsI(Tl) scintillator detector placed downstream of the Hall A beam-dump at Jefferson Lab, receiving up to 10$$^{22}$$ electrons-on-target (EOT) in 285 days. This experiment (Beam-Dump eXperiment or BDX) would be sensitive to elastic DM-electron and to inelastic DM scattering at the level of 10 counts per year, reaching the limit of the neutrino irreducible background. The distinct signature of a DM interaction will be an electromagnetic shower of few hundreds of MeV, together with a reduced activity in the surrounding active veto counters. A detailed description of the DM particle $$\\chi$$ production in the dump and subsequent interaction in the detector has been performed by means of Monte Carlo simulations. Different approaches have been used to evaluate the expected backgrounds: the cosmogenic background has been extrapolated from the results obtained with a prototype detector running at INFN-LNS (Italy), while the beam-related background has been evaluated by GEANT4 Monte Carlo simulations. The proposed experiment will be sensitive to large regions of DM parameter space, exceeding the discovery potential of existing and planned experiments in the MeV-GeV DM mass range by up to two orders of magnitude.« less

The {pi}{sub 1}(1600), a J{sup PC} = 1{sup {-+}} exotic meson has been observed by experiments using pion beams. Theorists predict that photon beams could produce gluonic hybrid mesons, of which the {pi}{sub 1}(1600) is a candidate, at enhanced levels relative to pion beams. The g12 rungroup at Jefferson Lab's CEBAF Large Acceptance Spectrometer (CLAS) has recently acquired a large photoproduction dataset, using a liquid hydrogen target and tagged photons from a 5.71 GeV electron beam.

Within the borders of modern Poland there are numerous barracks units erected at the turn of the 19th and 20th centuries by the invaders from Russia, Austria and Prussia. Former barracks are a clear element of the history of the place. Historical complexes have a strong influence on the urban landscape and on building their former and contemporary identity. The analysis of functional and landscape absorption of postmodern complexes allows for their adaptation and modern use without limiting the readability of historical values. For this reason, their landscape should be protected comprehensively within the scope of subsequent exposure scales. The aim of the work is to justify the conditions of comprehensive protection of the fortified landscape of the former barracks of the former Russian partition in the landscape of contemporary Polish cities. The article contains a review of the literature on the protection, supplement and access to fortified buildings from the turn of the 19th and 20th centuries in contemporary Poland. A review of current research conducted at various academic centres in Poland, concerning the exposition of fortified buildings in the landscape, is presented. Particular attention was paid to the scales and forms of exposition, proposed for the fortifications and barracks. The paper presents justification for the protection of barracks complexes from the turn of the 19th and 20th centuries in the landscape of Polish cities of the former Russian partition area. Protection of the landscape was proposed in the following scales: superregional, landscape (panorama of the centre), urban (urban structure of the complex in the context of the urban space), architectural and landscape interiors of the complex (WAK) such as alleys, alarm squares, greenery) and detail (view of the building from the outside), interior of the building (characteristic interior spaces, e.g. home chapels, staircases).

The Jefferson Lab Hall A experiment has measured the 3He(e,e'p) reaction cross sections. The separation of the longitudinal and transverse response functions for the two-body breakup reaction in parallel kinematics allows to study the bound proton electromagnetic properties in the 3He nucleus and the involved nuclear mechanisms beyond impulse approximation. Preliminary cross sections show some disagreement with theoretical predictions for the forward angles kinematics around 0 MeV/c missing momenta, and sensitivity to final state interactions and 3He wave functions for missing momenta of 300 MeV/c.

A shashlik-type electromagnetic calorimeter will be produced in Hall A of Jefferson Laboratory for the Solenoidal Large Intensity Device (SoLID). Wavelength-shifting (WLS) fibers and clear fibers will be used as the light guide part of the calorimeter. The blue light from scintillators is converted into green light by WLS fibers and is carried out to the back of the calorimeters for readout. Since the magnetic field of SoLID reaches about 1.5 T behind the calorimeters, the design is to use clear fibers to further guide the light out of the solenoid for readout by PMTs. Therefore, it is important to study the perfomance of WLS and clear fibers. This paper describes a comparative test of two different WLS fibers and a light attenuation test for a clear fiber. The results show that the performance of the two WLS fibers is the same under large curvature bending, and that the bending has no effect on the light transmission through the clear fiber. In addition, a comparison test for two fiber end-face reflective materials is also reported. It reveals that the use of silver ink as a reflective material can increase the light yield by 30%. Thereby, an optimized prototype based on the above experimental results was built and the basic performance was tested.

Natural radioactivity in geothermal waters, Alhambra Hot Springs and nearby areas, Jefferson County, Montana

USGS Publications Warehouse

Leonard, Robert B.; Janzer, Victor J.

1978-01-01

Radioactive hot springs issue from a fault zone in crystalline rock of the Boulder batholith at Alhambra, Jefferson County, in southwestern Montana. The discharge contains high concentrations of radon, and the gross alpha activity and the concentration of adium-226 exceed maximum levels recommended by the Environmental Protection Agency for drinking water. Part of the discharge is diverted for space heating, bathing, and domestic use. The radioactive thermal waters at measured temperatures of about 60°C are of the sodium bicarbonate type and saturated with respect to calcium carbonate. Radium-226 in the rock and on fractured surfaces or coprecipitated with calcium carbonate probably is the principal source of radon that is dissolved in the thermal water and discharged with other gases from some wells and springs. Local surface water and shallow ground water are of the calcium bicarbonate type and exhibit low background activity. The temperature, percent sodium, and radioactivity of mixed waters adjacent to the fault zone increase with depth. Samples from most of the major hot springs in southwestern Montana have been analyzed for gross alpha and beta activity. The high level of radioactivity at Alhambra appears to be related to leaching of radioactive material from siliceous veins by ascending thermal waters and is not a normal characteristic of hot springs issuing from fractured crystalline rock in Montana.

In medical sciences, commitment to lifelong learning has been expressed as an important element. Today, due to the rapid development of medical information and technology, lifelong learning is critical for safe medical care and development in medical research. JeffSPLL is one of the scales for measuring lifelong learning among the staff of medical sciences that has never been used in Iran. The aim of the present study was to determine the factor structure and reliability of the Persian version of JeffSPLL among Persian-speaking staff of universities of medical sciences in Iran. This study was a cross-sectional study, methodologically, that was conducted in 2012-2013. In this study, 210 staff members of Birjand University of Medical Sciences were selected. Data collection tool was the Persian version of JeffSPLL. To investigate the factor structure of this tool, confirmatory factor analysis was used and to evaluate the model fit, goodness-of-fit indices, root mean square error of approximation (RMSEA), the ratio of chi-square to the degree of freedom associated with it, comparative fit index (CFI), and root mean square residual (RMR) were used. To investigate the reliability of tool, Cronbach's alpha was employed. Data analysis was conducted using LISREL8.8 and SPSS 20 software. Confirmatory factor analysis showed that RMSEA was close to 0.1, and CFI and GFI were close to one. Therefore, four-factor model was appropriate. Cronbach's alpha was 0.92 for the whole tool and it was between 0.82 and 0.89 for subscales. The present study verified the four-factor structure of the 19-item Persian version of JeffSPLL that included professional learning beliefs and motivation, scholarly activities, attention to learning opportunities, and technical skills in information seeking among the staff. In addition, this tool has acceptable reliability. Therefore, it was appropriate to assess lifelong learning in the Persian-speaking staff population.

In an experiment conducted on the Jefferson Laboratory IR free-electron laser driver, the effects of coherent synchrotron radiation (CSR) on beam quality were studied. The primary goal of this work was to explore CSR output and effect on the beam with variation of the bunch compression in the IR recirculator. Here we examine the impact of CSR on the average energy loss as a function of bunch compression as well as the impact of CSR on the energy spectrum of the bunch. Simulation of beam dynamics in the machine, including the one-dimensional CSR model, shows very good agreement with the measured effect of CSR on the average energy loss as a function of compression. Finally, a well-defined structure is observed in the energy spectrum with a feature in the spectrum that varies as a function of the compression. This effect is examined in simulations, as well, and a simple explanation for the variation is proposed.

Six diamond core holes totaling 2, 201 feet were drilled by the. U, S. Bureau of Mines under contract to the U. S. Atomic Energy Commission at the Old Leyden coal mine, Jefferson County, Colo. The holes were spotted on the basis of geologic mapping by the U. S. Geological survey and were drilled to explore the lateral and downward extent of a uranium-bearing coal and the associated carnotite deposits in the adjacent sandstone° The data obtained from the diamond-core holes helped to explain the geology and structural control of the deposit. The uranium is most abundant in a coal bed that in places has been brecciated by shearing. and then altered to a hard, dense, and silicified rock. The uraniferous coal is in the nearly vertical beds of the Laramie formation of Upper Cretaceous age. Small lenticular bodies of uraniferous material, 50 feet long, 25 to 30 feet wide, and 2 to 4 feet thick, occur at intervals in the coal and silicified coal over a strike length of about 800 feet. These bodies contain 0.10 to 0.50 percent uranium. Data obtained from the drilling indicate a discontinuous radioactive zone between these higher-grade bodies; assays of samples from the cores range from 0.001 to 0.10 percent uranium. All drill holes were probed by Survey and A. E. C. logging equipment and showed anomalies where the core assayed more than 0.005 percent uranium. Material of ore grade--0.10 percent uranium--was found in one core; the rock in the other five holes was of lower grade. The presence of the radioactive zone in all holes suggests, however, that uranium is distributed irregularly in a southerly plunging deposit which is exposed in the adit, on the outcrop, and in other diamond-drill holes that were put down by the lessee.

Harmonic Kicker RF Cavity for the Jefferson Lab Electron-Ion Collider EM Simulation, Modification, and Measurements

Overstreet, Sarah; Wang, Haipeng

2017-09-01

An important step in the conceptual design for the future Jefferson Lab Electron-Ion Collider (JLEIC) is the development of supporting technologies for the Energy Recovery Linac (ERL) Electron Cooling Facility. The Harmonic Radiofrequency (RF) kicker cavity is one such device that is responsible for switching electron bunches in and out of the Circulator Cooling Ring (CCR) from and to the ERL, which is a critical part of the ion cooling process. Last year, a half scale prototype of the JLEIC harmonic RF kicker model was designed with resonant frequencies to support the summation of 5 odd harmonics (95.26 MHz, 285.78 MHz, 476.30 MHz, 666.82 MHz, and 857.35 MHz); however, the asymmetry of the kicker cavity gives rise to multipole components of the electric field at the electron-beam axis of the cavity. Previous attempts to symmetrize the electric field of this asymmetrical RF cavity have been unsuccessful. The aim of this study is to modify the existing prototype for a uniform electric field across the beam pathway so that the electron bunches will experience nearly zero beam current loading. In addition to this, we have driven the unmodified cavity with the harmonic sum and used the wire stretching method for an analysis of the multipole electric field components.

This report presents and describes geophysical logs for six boreholes in Lariat Gulch, a topographic gulch at the former U.S. Air Force site PJKS in Jefferson County near Denver, Colorado. Geophysical logs include gamma, normal resistivity, fluid-column temperature and resistivity, caliper, televiewer, and heat-pulse flowmeter. These logs were run in two boreholes penetrating only the Fountain Formation of Pennsylvanian and Permian age (logged to depths of about 65 and 570 feet) and in four boreholes (logged to depths of about 342 to 742 feet) penetrating mostly the Fountain Formation and terminating in Precambrian crystalline rock, which underlies the Fountain Formation. Data from the logs were used to identify fractures and bedding planes and to locate the contact between the two formations. The logs indicated few fractures in the boreholes and gave no indication of higher transmissivity in the contact zone between the two formations. Transmissivities for all fractures in each borehole were estimated to be less than 2 feet squared per day.

An empirical study of the predictive validity of number grades in medical school using 3 decades of longitudinal data: implications for a grading system.

PubMed

Gonnella, Joseph S; Erdmann, James B; Hojat, Mohammadreza

2004-04-01

Context It is important to establish the predictive validity of medical school grades. The strength of predictive validity and the ability to identify at-risk students in medical schools depends upon assessment systems such as number grades, pass/fail (P/F) or honours/pass/fail (H/P/F) systems. Objective This study was designed to examine the predictive validity of number grades in medical school, and to determine whether any important information is lost in a shift from number to P/F and H/P/F grading systems. Subjects The participants in this prospective, longitudinal study were 6656 medical students who studied at Jefferson Medical College over 3 decades. They were grouped into 10 deciles based on their number grades in Year 1 of medical school. Methods Participants were compared on academic accomplishments in Years 2 and 3 of medical school, medical school class rank, delayed graduation and attrition, performance on medical licensing examinations and clinical competence ratings in the first postgraduate year. Results Results supported the short- and longterm predictive validity of the number grades. Ratings of clinical competence beyond medical school were predicted by number grades in medical school. We demonstrated that small differences in number grades are statistically meaningful, and that important information for identifying students in need of remedial education is lost when students who narrowly meet faculty's expectations are included with the rest of the class in a broad 'pass' category. Conclusions The findings refute the argument that knowledge of sciences basic to medicine is not critical to subsequent performance in medical school and beyond if an appropriate evaluation system is used. Furthermore, the results of this study raise questions about abandoning number grades in favour of a pass/fail system. Consideration of these findings in policy decisions regarding assessment systems of medical students is recommended.

Socio-demographic, academic, and professional background information was collected. A total of 104 residents (67 from Spain and 32 from Latin America) answered and returned the questionnairess. The JSE-HP showed adequate psychometric properties. The empathy mean score of Spanish group was higher than that of the Latin American group (P=.01). Differences in the development of empathy were associated with: the development of professional models (P<.001), the positive encounter with other professionals (P=.001), and with a continuing medical education (P=.008). Some factors involved in the development of empathy that are sensitive to cultural influence have been characterised. The development of future research areas is suggested.

Objective. To validate the Jefferson Scale of Empathy-Health Profession Students version (JSE-HPS) in pharmacy students. Methods. The JSE-HPS (20 items), adapted from the original Jefferson Scale of Empathy for use among students in the healthcare professions, was completed by 187 first-year pharmacy students at Midwestern University Chicago College of Pharmacy. Results. Two factors, “perspective-taking” and “compassionate care,” emerged from factor analysis in this study, accounting for 31% and 8% of the variance, respectively. These factors are similar to the prominent ones reported in previous research involving physicians and medical students, supporting the construct validity of this instrument for pharmacy students. In the current study, mean JSE-HPS score was comparable to those reported for medical students, and consistent with previous findings with medical students and physicians. Women scored significantly higher than men. Conclusions. Findings support the construct validity and reliability of the JSE-HPS for measuring empathy in pharmacy students. PMID:21931447

Medical student professionalism education is challenging in scope, purpose, and delivery, particularly in the clinical years when students in large universities are dispersed across multiple clinical sites. We initiated a faculty-facilitated, peer small group course for our third year students, creating virtual classrooms using social networking and online learning management system technologies. The course emphasized narrative self-reflection, group inquiry, and peer support. We conducted this study to analyze the effects of a professionalism course on third year medical students' empathy and self-reflection (two elements of professionalism) and their perceptions about the course. Students completed the Groningen Reflection Ability Scale (GRAS) and the Jefferson Scale of Empathy (JSE) before and after the course and provided anonymous online feedback. The results of the JSE before and after the course demonstrated preservation of empathy rather than its decline. In addition, there was a statistically significant increase in GRAS scores (p < 0.001), suggesting that the sharing of personal narratives may foster reflective ability and reflective practice among third year students. This study supports previous findings showing that students benefit from peer groups and discussion in a safe environment, which may include the use of a virtual group video platform.

The authors designed the present study to examine the association between individuals' scores on the Jefferson Scale of Physician Empathy (JSPE; M. Hojat, J. S. Gonnella, S. Mangione, T. J. Nasca, & M. Magee, 2003; M. Hojat, J. S. Gonnella, T. J. Nasca, S. Mangione, M. Vergare, & M. Magee, 2002; M. Hojat, S. Mangione, T. J. Nasca, M. J. M. Cohen, J. S. Gonnella, J. B. Erdmann, J. J. Veloski, & M. Magee, 2001), a self-report empathy scale, during medical school and ratings of their empathic behavior made by directors of their residency training programs 3 years later. Participants were 106 physicians. The authors examined the relationships between scores on the JSPE (with 20 Likert-type items) at the beginning of the students' 3rd year of medical school and ratings of their empathic behavior made by directors of their residency training programs. Top scorers on the JSPE in medical school, compared to Bottom scorers, obtained a significantly higher average rating of empathic behavior in residency 3 years later (p < .05, effect size = 0.50). The findings support the long-term predictive validity of the self-report empathy scale, JSPE, despite different methods of evaluations (self-report and supervisors' ratings) and despite a time interval between evaluations (3 years). Because empathy is relevant to prosocial and helping behavior, it is important for investigators to further enhance our understanding of its correlates and outcomes among health professionals.

Background Prenatal alcohol use, a leading preventable cause of birth defects and developmental disabilities, remains a prevalent public health concern in the United States. This study aims to detect the proportion and correlates of prenatal alcohol use in the prenatal care settings in Alabama. Prenatal care settings were chosen because of their potential as stable locations to screen for and to reduce prenatal alcohol use within a community. Methods We conducted a cross-sectional study of 3,046 women in the 22 and 23 weeks of gestation who sought prenatal care in eight community-based public clinics and participated in the Perinatal Emphasis Research Center project in Jefferson County, Alabama, in 1997–2001. Frequency and quantity of alcohol use in the past 3 months were assessed by research nurses during face-to-face interviews. We conducted logistic regression analyses to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI) of correlates of prenatal alcohol use. Results Participants were predominantly young, African American, and unmarried, 86.5% on Medicaid. The proportion of alcohol use in the second trimester of pregnancy was 5.1%; 0.3% of women reported 4 or more drinks on a drinking day to research nurses. Older maternal age (OR=1.11; 95% CI=1.08–1.15), use of welfare (OR=1.43; 95% CI=1.02–2.02), and male partner–perpetrated violence (OR=2.96; 95% CI=1.92–4.56) were positively associated with elevated risk of prenatal alcohol use. Protective factors included higher levels of self-esteem (OR=0.94; 95% CI=0.89–0.98) and more years of education (OR=0.88; 95% CI=0.78–0.98). Conclusions Prenatal alcohol use remains a public health issue among low-income pregnant women in Jefferson County, Alabama. Research nurses detected it in the second trimester. Future studies need to encourage screening for prenatal alcohol use in the prenatal care settings by obstetrician-gynecologists, family physicians, nurses, and midwifes. Combined

Evaluation of Light Collection System for Pion and Kaon Experiments in Hall C at Jefferson Lab

The neutral pion and the kaon are opportune to study the hadron structure through General Parton Distributions, which can be viewed as spatial densities at different momenta of the quarks inside the proton. To study hadron structure with pion or kaon experiments in Hall C at 12 GeV Jefferson Lab, one must analyze the final state neutral pions and kaons and their decay products. For the analysis of these particles, dedicated detectors based on the Cherenkov or scintillation mechanism are used, e.g. the HMS and SHMS aerogel detectors and the PbWO4-based Neutral Particle Spectrometer. A critical part of these detectors is the light collection system. Photomultiplier Tubes (PMTs) have many advantages, however, they are sensitive to magnetic fields and can get damaged by elevated helium levels in the atmosphere. An alternative to PMTs are Avalanche Photodiodes (APDs). APDs are sensitive to background noise, temperature, and radiation. It is thus important to evaluate the benefits of each light collection system and optimize operating conditions to ensure performance over a reasonably long time. I will present a performance study of PMTs exposed to elevated levels of helium and a comparison of APDs as alternatives, as well as new, compact readout methods.

To provide patient-centred holistic care, doctors must possess good interpersonal and empathic skills. Medical schools traditionally adopt a skills-based approach to such training but creative engagement with the arts has also been effective. A novel arts-based approach may help medical students develop empathic understanding of patients and thus contribute to medical students' transformative process into compassionate doctors. This study aimed to evaluate the impact of an arts-making workshop on medical student empathy. This was a mixed-method quantitative-qualitative study. In the 2011-12 academic year, all 161 third year medical students at the University of Hong Kong were randomly allocated into either an arts-making workshop or a problem-solving workshop during the Family Medicine clerkship according to a centrally-set timetable. Students in the arts-making workshop wrote a poem, created artwork and completed a reflective essay while students in the conventional workshop problem-solved clinical cases and wrote a case commentary. All students who agreed to participate in the study completed a measure of empathy for medical students, the Jefferson Scale of Empathy (JSE) (student version), at the start and end of the clerkship. Quantitative data analysis: Paired t-test and repeated measures ANOVA was used to compare the change within and between groups respectively. Qualitative data analysis: Two researchers independently chose representational narratives based on criteria adapted from art therapy. The final 20 works were agreed upon by consensus and thematically analysed using a grounded theory approach. The level of empathy declined in both groups over time, but with no statistically significant differences between groups. For JSE items relating to emotional influence on medical decision making, participants in the arts-making workshop changed more than those in the problem-solving workshop. From the qualitative data, students perceived benefits in arts

An Exploratory Study of γp -> ϕ (K+K-) ω (π+π-π0) p in the GlueX Experiment at Jefferson Lab

Banks, Christopher; Salgado, Carlos; GlueX Collaboration

Mesons are subatomic particles that have intermediate masses between electrons and protons and manifest as quark-antiquark pairs kept together by the strong force (gluons). Quantum Chromodynamics (QCD) states the possibility for mesons manifested only as gluons (glueballs) or as quarks and gluons (hybrids). Some of those hybrid mesons could have quantum numbers that are inaccessible to conventional mesons (exotics). The GlueX detector at Jefferson Lab was built to search for exotic mesons at intermediate energies (2-3 GeV masses). The reaction γp -> ϕ (K+K-) ω (π+π-π0) p is of interest for this study. By simulating the detector and the reconstruction acceptance and efficiency, and by using expected signals and backgrounds through a detailed Monte Carlo, we have studied the possibilities of observing this reaction with the present GlueX configuration.

We have conducted this study to assess medical students' empathy and to examine empathy differences by students' socio-demographic characteristics, including gender, and specialty preference. We have conducted a cross-sectional and descriptive research. Among 595 medical students registered at the Federal University of Santa Catarina (Brazil) in 2012, we have selected a sample of 320 enrolled in the first, third, fifth, seventh, ninth, eleventh, and in the last semester of the course. The response rate obtained was 70.6% (n=226). Data was collected by using a self-report questionnaire, and the variables analyzed included course semester, socio-demographic characteristics (such as age, gender, household monthly income and parents level of education), students' specialty preference, and empathy assessed by the Jefferson Scale of Empathy. We have used descriptive statistics, 95% Confidence Interval for percentages, Student's t-test, and Analysis of Variance to analyze the data. Mean empathy among students was (M=119.7, SD=9.9), with no difference by according to semester (F=1.5, p=.2). Empathy means were higher among females (M=118.3, SD=10.6) than among males (M=121.0, SD=9.3, t=-2.1, p=.032). Students who preferred a people-oriented specialty obtained significantly higher mean scores (M=121.5, SD=8.1) in comparison to students who preferred technology-oriented specialties (M=118.0, SD=11.3, t=2.4, p=.02). Our study has found consistently high scores of empathy among medical students enrolled in all levels of training at the Federal University of Santa Catarina, and higher empathy among women and students who intend to pursue a people-oriented specialty. Conclusions on higher empathy among medical students require further study.

Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab: an update on PR12-16-001

Battaglieri, M.

This document is an update to the proposal PR12-16-001 Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab submitted to JLab-PAC44 in 2016 reporting progress in addressing questions raised regarding the beam-on backgrounds. The concerns are addressed by adopting a new simulation tool, FLUKA, and planning measurements of muon fluxes from the dump with its existing shielding around the dump. First, we have implemented the detailed BDX experimental geometry into a FLUKA simulation, in consultation with experts from the JLab Radiation Control Group. The FLUKA simulation has been compared directly to our GEANT4 simulations and shown to agreemore » in regions of validity. The FLUKA interaction package, with a tuned set of biasing weights, is naturally able to generate reliable particle distributions with very small probabilities and therefore predict rates at the detector location beyond the planned shielding around the beam dump. Second, we have developed a plan to conduct measurements of the muon ux from the Hall-A dump in its current configuration to validate our simulations.« less

Uranium occurrences in the Golden Gate Canyon and Ralston Creek areas, Jefferson County, Colorado

Pitchblende, associated with base-metal sulfides, has been found at nine localities in the northern part of Jefferson County, Colo., in shear zones that cut pre-Cambrian metamorphic and igneous rocks, chiefly hornblende gneiss, biotite schist, and granite pegmatite. The known deposits are in the vicinity of Halston Creek and Golden Gate Canyon, in the foothills of the Colorado Front Range and about 15 miles east of the pitchblende-producing area of the Central City district. Two of the pitchblende occurrences were found by a local prospector in 1949; the seven other deposits were found by Geological Survey. personnel in 1951-52. The pitchblende deposits, with one exception, are in major shear zones that contain veinlike bodies of carbonate-rich breccia that ranges from 1 to 5 feet in thickness. The breccias probably are related to the Laramide faults, or 'breccia reefs' of similar trend, mapped by Loverinq and Goddard (1950). The breccias are composed of fragments of bleached and iron-stained wall rock, usually hornblende gneiss, that have been cut by veins and cemented by carbonate minerals, quartz, and orthoclase(?). Pitchblende and associated ore minerals, chiefly copper sulfides, occur in and along the margins of the breccias and apparently were introduced at a late stage of the carbonate deposition. At one deposit, the Buckman, the pitchblende is in narrow shear zones not closely related to any large breccia bodies. Secondary uranium minerals are subordinate except at the Schwartzwalder mine, where torbernite and metatorbernite are common. Some alteration of pitchblende to non-opaque materials, believed to be hydrated oxides, has been noted in ore from two of the deposits.

It is known that empathic communication is important for physicians to achieve higher patient satisfaction and health outcomes. Emotional intelligence (EI), empathy and personality in medical students predict students' individual disposition and their emotional and empathic perceptions. This study aimed to investigate: 1) The association between empathy, EI and personality, and 2) Gender differences in the association between empathy, EI and personality. Participants were 357 1st year medical students from 2008 to 2011 at one medical school in Japan. Students completed self-report questionnaires comprising three validated instruments measuring EI: Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF), empathy: Jefferson Scale of Physician Empathy- student version (JSPE) and personality: NEO-Five-Factor Inventory (NEO-FFI), which explores 5 dimensions of personality Neuroticism (N), Extraversion (E), Openness to experience (O), Agreeableness (A), and Conscientiousness (C). Pearson Correlations showed weak association between TEIQue-SF and JSPE. TEIQue-SF and NEO-FFI showed positive correlation for E and C, and strong negative correlation for N and weak positive correlation for A and O. Weak positive correlation between JSPE and the NEO-FFI were observed for E and A. Although effect sizes were small, N, A and empathy were significantly higher in females (unpaired t-test). However, hierarchical multiple-regression analysis when controlling for gender and personality showed no association between EI, empathy and gender. A, TEIQue-SF and N were found to make small contributions in respect of predictions for JSPE. Personality contributed significantly to the prediction of TEIQue-SF. N had the largest independent negative contribution (β = - 0,38). In our study population of 1st year medical students, females had significantly higher N, A and empathy scores than males. Medical students' N score was strongly negatively associated with EI. Empathy was

To prepare students pursuing surgical careers, we devised a senior subinternship curriculum supplement that focused on the acquisition of technical skills required of surgical residents. We hypothesized that more assertive students, those that accomplished more of the curriculum, would perform better on a technical skills Objective Structured Clinical Examination (OSCE). Senior medical students rotating on their first general surgery subinternship were administered a 6-station OSCE on the first day of their subinternship and again during the final week of the month-long rotation. A self-directed, 38-task "scavenger hunt" representing common intern level clinical skills, procedures, and patient care activities was provided to each student. The study was performed at Jefferson Medical College, a large, private medical school in Philadelphia, PA. Forty-nine senior students completed surgical subinternships between July 2009 and September 2010, and participated both in the pre-/post-OSCEs and the scavenger hunt. Students performed significantly better on the post-rotation OSCE than on the pre-rotation OSCE; 70.2% ± 8.1% vs. 60.4% ± 12.0%, p < 0.0001. Assertiveness scores from the "scavenger hunt" did not correlate with final OSCE scores (r = -0.328, p = 0.25), and were negatively correlated with the change between pre- and post-OSCE scores (r = -0.573, p < 0.04). Individual student assertiveness scores were determined by the number of tasks completed over the course of the rotation. As surgical education becomes more streamlined with evolving work hour restrictions, medical school education is playing an increasingly pivotal role in preparing students for internship. In our study, individual assertiveness in completing structured self-directed learning tasks did not directly predict the acquisition of proficiency in technical skills. We feel assertiveness is overshadowed by other factors that may carry more weight in terms of technical skills acquisition. Further

Empathy is a crucial attribute within the physician-patient relationship. This study aimed to evaluate the empathy levels of students in the College of Medicine at Hawler Medical University (HMU) in Erbil city, Iraq. This cross-sectional study took place between January and May 2015 and included all medical undergraduates enrolled at HMU (n = 989). The validated self-administered English language version of the Jefferson Scale of Physician Empathy-Student Version (JSPE-SV) was used to measure empathy levels. Students reported their conformity to each statement of the 20-item questionnaire on a 7-point Likert scale. Levels of empathy were considered directly relative to their final score. A total of 927 students completed the questionnaire (response rate: 93.7%). The male-to-female ratio was 0.72:1 and the mean age was 21.3 ± 1.4 years. The mean empathy score was 101.9 ± 19.2. Female students had significantly higher empathy (P = 0.023) and more frequently chose people-oriented specialties (P = 0.001) than males. First-year students reported the highest mean score (112.9 ± 20.1) while fourth-year students had the lowest (92.7 ± 16.0). There was a significant decline in mean scores between first- and second-year male students (P = 0.020) and first- and fourth-year male students (P = 0.050). Students who chose people-oriented specialties had significantly higher scores than those who chose technology-oriented specialties (P = 0.002). The studied cohort of HMU students demonstrated low empathy levels. As such, the inclusion of empathy instruction in medical school curricula is recommended to promote professionalism and patient welfare.

This study aims to assess and compare objective and subjective scores of empathy in final-year medical students by using firstly a validated student self-assessment just prior to the psychiatry objective structured clinical examination (OSCE), and then comparing this to clinical examiner's and simulated patient's (SP's) assessments of empathy of students using a Global Rating of Empathy scale (GRE) during a psychiatry OSCE. In 2011, all final-year medical students in the University College Dublin were invited to complete a subjective, self-assessed empathy questionnaire (The Jefferson scale of physician empathy-student version (JSPE-S)). They were also assessed for empathy in four OSCEs by the clinical examiner and the SP acting in that OSCE scenario. Included in the analysis were 163 of 184 final-year students JSPE-S (88.6%) questionnaires. The female students scores on the JSPE-S were significantly higher than those of their male peers (t=3.34, p=0.001). Concurrent validity was greater between the SPs' assessments of empathy in the OSCE and the JSPE-S score than between the clinical examiners assessments of empathy and the JSPE-S score (r=0.23, p<0.005; r=0.14, p<0.08). Inter-rater reliability of SP's and clinical examiner's using the GRE was found to be high (F=0.868 (df=171, 171), p value<0.001). SPs may be valid assessors of empathy in medical students during an OSCE.

Nursing research is the systematic collection and analysis of data about clinically important phenomena. While there are norms for conducting research and rules for using certain research procedures, the reader must always filter the research report against his or her nursing knowledge. The most common questions a reader should ask are "Does it make sense? Can I think of any other reasonable explanation for the findings? Do the findings fit what I have observed?" If the answers are reasonable, research findings from carefully conducted studies can provide a basis for making nursing decisions. One of the earliest accounts of nursing research, which indicates the power of making systematic observations, was Florence Nightingale's study. It compared deaths among soldiers in the Crimean War with deaths of soldiers in the barracks of London. Her research demonstrated that soldiers in the barracks had a much higher death rate than did the soldiers at war. On the basis of the study, sanitary conditions in the barracks were changed substantially.

Development of a Bunched Beam Electron Cooler based on ERL and Circulator Ring Technology for the Jefferson Lab Electron-Ion Collider

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

Benson, Stephen V.; Derbenev, Yaroslav S.; Douglas, David R.

Jefferson Lab is in the process of designing an electron ion collider with unprecedented luminosity at a 45 GeV center-of-mass energy. This luminosity relies on ion cooling in both the booster and the storage ring of the accelerator complex. The cooling in the booster will use a conventional DC cooler similar to the one at COSY. The high-energy storage ring, operating at a momentum of up to 100 GeV/nucleon, requires novel use of bunched-beam cooling. There are two designs for such a cooler. The first uses a conventional Energy Recovery Linac (ERL) with a magnetized beam while the second usesmore » a circulating ring to enhance both peak and average currents experienced by the ion beam. This presentation will describe the design of both the Circulator Cooling Ring (CCR) design and that of the backup option using the stand-alone ERL operated at lower charge but higher repetition rate than the ERL injector required by the CCR-based design.« less

Understanding medical student empathy is important to future patient care; however, the definition and development of clinical empathy remain unclear. The authors sought to examine the underlying constructs of two of the most widely used self-report instruments-Davis's Interpersonal Reactivity Index (IRI) and the Jefferson Scale of Empathy version for medical students (JSE-S)-plus, the distinctions and associations between these instruments. Between 2007 and 2014, the authors administered the IRI and JSE-S in three separate studies in five countries, (Brazil, Ireland, New Zealand, Portugal, and the United Kingdom). They collected data from 3,069 undergraduate medical students and performed exploratory factor analyses, correlation analyses, and multiple linear regression analyses. Exploratory factor analysis yielded identical results in each country, confirming the subscale structures of each instrument. Results of correlation analyses indicated significant but weak correlations (r = 0.313) between the total IRI and JSE-S scores. All intercorrelations of IRI and JSE-S subscale scores were statistically significant but weak (range r = -0.040 to 0.306). Multiple linear regression models revealed that the IRI subscales were weak predictors of all JSE-S subscale and total scores. The IRI subscales explained between 9.0% and 15.3% of variance for JSE-S subscales and 19.5% for JSE-S total score. The IRI and JSE-S are only weakly related, suggesting that they may measure different constructs. To better understand this distinction, more studies using both instruments and involving students at different stages in their medical education, as well as more longitudinal and qualitative studies, are needed.

Objective An effective career in medicine requires empathy and compassion, yet the demands of a medical education increase stress and decrease students' ability to connect with patients. However, research suggests mind-body practices improve psychological well-being. This study aimed to evaluate the psychological effects on medical students of an 11-week elective course, Embodied Health or EH, which combines yoga and meditation with neuroscience didactics. Methods The effects on 27 first- and second-year medical students were evaluated via surveys in four areas: empathy, perceived stress, self-regulation, and self-compassion. Scales used were 1. Jefferson Scale of Physician Empathy, which measures empathy among health students and professionals and medical students on a scale of 1 (least empathetic) to 7 (most empathetic); 2. Cohen's Perceived Stress Scale, a measure of the perceived uncontrollability of respondents' lives, from 0 (least stressed) to 4 (most stressed); 3. Self-Regulation Questionnaire, which measures the development and maintenance of planned behavior to achieve goals, from 1 (least self-regulated) to 5 (most self-regulated); and 4. Self-Compassion Scale, which measures self-criticism, from 1 (least self-compassionate) to 5 (most self-compassionate). Students also reflected on EH's impact on their well-being in a post-course essay. Results Self-regulation and self-compassion rose 0.13 (SD 0.20, p = 0.003) and 0.28 (SD 0.61, p = 0.04), respectively. Favorable changes were also seen in empathy and perceived stress, which went up by 0.11 (SD 0.50, p = 0.30) and down by 0.05 (SD 0.62, p = 0.70), respectively; these changes did not reach statistical significance. Students' essays were found to discuss the following recurrent themes: 1) Reconnection between mind and body; 2) Community in a competitive environment; 3) Increased mindfulness; 4) Confidence in use of mind-body skills with patients; and 5) Stress management. These themes overlapped with the

The MØLLER experiment at Jefferson Lab: search for physics beyond the Standard Model

The MO/LLER experiment at Jefferson Lab will measure the parity-violating analyzing power Az in the scattering of 11 GeV longitudinally polarized electrons from the atomic electrons in a liquid hydrogen target (Mo/ller scattering). In the Standard Model a non-zero Az is due to the interference of the electromagnetic amplitude and the weak neutral current amplitude, the latter mediated by the Z0 boson. Az is predicted to be 35.6 parts per billion (ppb) at the kinematics of the experiment. It is the objective of the experiment to measure Az to a precision of 0.73 ppb. This result would yield a measurement of the weak charge of the electron QWe to a fractional error of 2.3% at an average value Q2 of 0.0056 (GeV/c)2. This in turn will yield a determination of the weak mixing angle sin2θw with an uncertainty of ±0.00026(stat) ±0.00013(syst), comparable to the accuracy of the two best determinations at high energy colliders (at the Z0 pole). Consequently, the result could potentially influence the central value of this fundamental electroweak parameter, which is of critical importance in deciphering any signal of new physics that might be observed at the Large Hadron Collider (LHC). The measurement is sensitive to the interference of the electromagnetic amplitude with new neutral current amplitudes as weak as 10-3 GF from as yet unknown high energy dynamics, a level of sensitivity unlikely to be matched in any experiment measuring a flavor and CP conserving process in the next decade. This provides indirect access to new physics at multi-TeV scales in a manner complementary to direct searches at the LHC.

Neutron Detection Efficiency Optimization Studies of the Neutron Polarimeter for the C-GEN Electric Form Factor at Jefferson National Laboratory

NASA Astrophysics Data System (ADS)

Adzima, Ashley; Tireman, William; C-Gen Collaboration

The electric form factor is an important quantity to further the understanding of the atom and its constituent parts. The C-GEN collaboration at Jefferson National Laboratory plans to measure this fundamental quantity using recoil polarimetry. An efficient neutron polarimeter is essential for the collection of precise data and involves maximizing the ratio of elastic to inelastic events identified. The determination of the elastic to inelastic ratio of neutron events was simulated using GEANT-4 on 5 cm, 10 cm, and 15 cm thick detectors. Specific requirements were set in place by C-GEN to determine what marks an elastic event. Plots of neutron scattering events versus detector thickness were analyzed, and the ratio of elastic to inelastic events was extracted for each section per vertical slice, as well as an average ratio. The average ratio of elastic to inelastic events were 0.2206, 0.1706, and 0.1507 for the 5 cm, 10 cm, and 15 cm detectors, respectfully. The impact of these ratios on the statistics and costs of altering the polarimeter's original 10 cm detector design will be further discussed.

Monitoring and understanding ecosystems such as lakes and their watersheds is becoming increasingly important. Accelerated eutrophication threatens our drinking water sources. Many believe that the use of nutrients (e.g., road salts, fertilizers, etc.) near these sources may have negative impacts on animal and plant populations and water quality although it is unclear how to best balance broad community needs. The Jefferson Project is a joint effort between RPI, IBM and the Fund for Lake George aimed at creating an instrumented water ecosystem along with an appropriate cyberinfrastructure that can serve as a global model for ecosystem monitoring, exploration, understanding, and prediction. One goal is to help communities understand the potential impacts of actions such as road salting strategies so that they can make appropriate informed recommendations that serve broad community needs. Our semantic eScience team is creating a semantic infrastructure to support data integration and analysis to help trained scientists as well as the general public to better understand the lake today, and explore potential future scenarios. We are leveraging our RPI Tetherless World Semantic Web methodology that provides an agile process for describing use cases, identification of appropriate background ontologies and technologies, implementation, and evaluation. IBM is providing a state-of-the-art sensor network infrastructure along with a collection of tools to share, maintain, analyze and visualize the network data. In the context of this sensor infrastructure, we will discuss our semantic approach's contributions in three knowledge representation and reasoning areas: (a) human interventions on the deployment and maintenance of local sensor networks including the scientific knowledge to decide how and where sensors are deployed; (b) integration, interpretation and management of data coming from external sources used to complement the project's models; and (c) knowledge about

Estimation of peak-discharge frequency of urban streams in Jefferson County, Kentucky

1997-01-01

An investigation of flood-hydrograph characteristics for streams in urban Jefferson County, Kentucky, was made to obtain hydrologic information needed for waterresources management. Equations for estimating peak-discharge frequencies for ungaged streams in the county were developed by combining (1) long-term annual peakdischarge data and rainfall-runoff data collected from 1991 to 1995 in 13 urban basins and (2) long-term annual peak-discharge data in four rural basins located in hydrologically similar areas of neighboring counties. The basins ranged in size from 1.36 to 64.0 square miles. The U.S. Geological Survey Rainfall- Runoff Model (RRM) was calibrated for each of the urban basins. The calibrated models were used with long-term, historical rainfall and pan-evaporation data to simulate 79 years of annual peak-discharge data. Peak-discharge frequencies were estimated by fitting the logarithms of the annual peak discharges to a Pearson-Type III frequency distribution. The simulated peak-discharge frequencies were adjusted for improved reliability by application of bias-correction factors derived from peakdischarge frequencies based on local, observed annual peak discharges. The three-parameter and the preferred seven-parameter nationwide urban-peak-discharge regression equations previously developed by USGS investigators provided biased (high) estimates for the urban basins studied. Generalized-least-square regression procedures were used to relate peakdischarge frequency to selected basin characteristics. Regression equations were developed to estimate peak-discharge frequency by adjusting peak-dischargefrequency estimates made by use of the threeparameter nationwide urban regression equations. The regression equations are presented in equivalent forms as functions of contributing drainage area, main-channel slope, and basin development factor, which is an index for measuring the efficiency of the basin drainage system.

Hall, Dennis C.; Johnson, Carl J.

1979-01-01

In parts of Jefferson County, CO, water for domestic use from the fractured crystalline-rock aquifer contained excessive concentrations of major ions, coliform bacteria, trace elements, or radiochemicals. Based on results of analyses from 26 wells, water from 21 of the wells contained excessive concentrations of one or more constituents. Drinking water standards were exceeded for fluoride in water from 2 wells, nitrate plus nitrite in 2 wells, dissolved solids in 1 well, iron in 6 wells, manganese in 8 wells, zinc in 2 wells, coliform bacteria in 4 wells, gross alpha radiation in 11 wells and possibly 4 more, and gross beta radiation possibly in 1 well. Local variations in concentrations of 15 chemical constituents, specific conductance, and water temperature were statistically significant. Specific conductance increased significantly during 1973-75 only in the vicinity of Indian Hills. Annual range in depths to water in 11 observation wells varied from 1 to 15 feet. The shallowest water levels were recorded in late winter, usually in February. The deepest water levels occurred during summer or fall, depending on the well and the year. Three-year trends in water level changes in 6 of the 11 wells indicated decreasing water storage in the aquifer. (USGS).

Gain Evaluation of Micro-Channel-Plate Photomultipliers in the Upgraded High-B Test Facility at Jefferson Lab

NASA Astrophysics Data System (ADS)

Barber, Corinne; DIRC at EIC Collaboration

2015-10-01

The High-B test facility at Thomas Jefferson National Accelerator Facility allows researchers to evaluate the gain of compact photon sensors, such as Micro-Channel-Plate Photomultipliers (MCP-PMTs), in magnetic fields up to 5 T. These ongoing studies support the development of a Detector of Internally Reflected Cherenkov light (DIRC) to be used in an Electron Ion Collider (EIC). Here, we present our summer 2015 activities to upgrade and improve the facility, and we show results for MCP-PMT gain changes in high B-fields. To monitor the light stability delivered to the MCP-PMTs being tested, we implemented a Silicon Photomultiplier (SiPM) in the setup and calibrated the ADC reading this sensor. A 405-nm Light-Emitting Diode (LED) housed in an optical tube compatible with neutral density filters was also installed. The filters provide an alternative way of reducing the light output of the LED to operate the MCP-PMTs in a single-photon mode. We calibrated a set of filters by means of a photodiode and measured the photon flux at multiple positions relative to the LED. This information helped us to design 3D-printed holders unique to each MCP-PMT so that the photocathode receives the greatest amount of light. The improvements to the setup allow for more precise PMT gain evaluation. This team includes 7 collaborators/co-authors besides myself: Yordanka Ilieva, Kijun Park, Greg Kalicy, Carl Zorn, Pawel Nadel-Turonski, Tongtong Cao, and Lee.

Hydrologic and water-quality characterization and modeling of the Chenoweth Run basin, Jefferson County, Kentucky

2001-01-01

Rainfall, streamflow, and water-quality data collected in the Chenoweth Run Basin during February 1996?January 1998, in combination with the available historical sampling data, were used to characterize hydrologic conditions and to develop and calibrate a Hydrological Simulation Program?Fortran (HSPF) model for continuous simulation of rainfall, streamflow, suspended-sediment, and total-orthophosphate (TPO4) transport relations. Study results provide an improved understanding of basin hydrology and a hydrologic-modeling framework with analytical tools for use in comprehensive waterresource planning and management. Chenoweth Run Basin, encompassing 16.5 mi2 in suburban eastern Jefferson County, Kentucky, contains expanding urban development, particularly in the upper third of the basin. Historical water-quality problems have interfered with designated aquatic-life and recreation uses in the stream main channel (approximately 9 mi in length) and have been attributed to organic enrichment, nutrients, metals, and pathogens in urban runoff and wastewater inflows. Hydrologic conditions in Jefferson County are highly varied. In the Chenoweth Run Basin, as in much of the eastern third of the county, relief is moderately sloping to steep. Also, internal drainage in pervious areas is impeded by the shallow, fine-textured subsoils that contain abundant silts and clays. Thus, much of the precipitation here tends to move rapidly as overland flow and (or) shallow subsurface flow (interflow) to the stream channels. Data were collected at two streamflowgaging stations, one rain gage, and four waterquality- sampling sites in the basin. Precipitation, streamflow, and, consequently, constituent loads were above normal during the data-collection period of this study. Nonpoint sources contributed the largest portion of the sediment loads. However, the three wastewatertreatment plants (WWTP?s) were the source of the majority of estimated total phosphorus (TP) and TPO4 transport

In 2013, 15 clusters of mumps were notified in France; 72% (82/114) of the cases had been vaccinated twice with measles-mumps-rubella vaccine. To determine whether the risk of mumps increased with time since the last vaccination, we conducted a case-control study among clusters in universities and military barracks. A confirmed case had an inflammation of a salivary gland plus laboratory confirmation in 2013. A probable case presented with inflammation of a salivary gland in 2013 either lasting for > 2 days or with epidemiological link to a confirmed case. Controls had no mumps symptoms and attended the same university course, student party or military barracks. We collected clinical and vaccination data via web questionnaire and medical records. We calculated adjusted odds ratios (aOR) using logistic regression. 59% (50/85) of cases and 62% (199/321) of controls had been vaccinated twice. The odds of mumps increased for twice-vaccinated individuals by 10% for every year that had passed since the second dose (aOR 1.10; 95% confidence interval (CI): 1.02-1.19; p = 0.02). Mumps immunity waned with increasing time since vaccination. Our findings contributed to the French High Council of Public Health's decision to recommend a third MMR dose during outbreaks for individuals whose second dose dates > 10 years.

Applying energy-conservation retrofits to standard Army buildings: Data analysis and recommendations. Final report

This report describes the data analysis and recommendations of a project demonstrating the energy performance of theoretically based retrofit packages on existing standard Army building at Fort Carson, CO. Four standard designs were investigated: a motor vehicle repair shop, the Type 64 (L-shaped) barracks, an enlisted personnel mess hall, and a two-company, rolling-pin-shaped barracks for enlisted personnel. The tested conservation measures included envelope and system modifications. Energy data were gathered and analyzed from 14 buildings. Based on measured savings and current costs of fuel and construction, none of the four original packages are life-cycle cost-effective at present, but two maymore » become effective in the near future. Of higher priority for energy and cost savings is the improvement of building operations, in particular heat production and distribution systems, which lack efficiency and control. Followup work at the L-shaped barracks yielded substantial savings, with a saving-to-investment ration of 5 to 1. Cost scenarios, energy models, and building were developed for the original retrofits to assess applicability elsewhere and in the future.« less

The Pennsylvania Anatomy Act of 1883: Weighing the Roles of Professor William Smith Forbes and Senator William James McKnight.

PubMed

Wright, James R

2016-10-01

Effective Anatomical Acts transformed medical education and curtailed grave-robbing. William S. Forbes, Demonstrator of Anatomy at Jefferson Medical College in Philadelphia, authored the Pennsylvania Anatomy Act of 1867, but it was ineffective. In December of 1882, Forbes and accomplices were charged with grave-robbing. Forbes was acquitted in early 1883, but his accomplices were all convicted; nevertheless, these events precipitated a strengthened Anatomy Act in 1883. Forbes was crowned the Father of the Pennsylvania Anatomy Act and was revered by the Philadelphia medical community for his personal sacrifices for medical education; they even paid his legal fees. Over the remainder of his life, Forbes received many honors. However, there was a second major player, rural doctor William J. McKnight, a convicted grave-robber and State Senator. The evidence shows that Forbes precipitated the crisis, which was a racial powder keg, and then primarily focused on his trial, while McKnight, creatively working behind the scenes in collaboration with Jefferson, Anatomy Professor William H. Pancoast, used the crisis to draft and pass transformative legislation enabling anatomical dissection at Pennsylvania medical schools. While not minimizing Forbes suffering throughout these events, McKnight should be appropriately recognized for his initiative and contributions, which far exceeded those of Forbes. © The Author 2016.

Transient calibration of a groundwater-flow model of Chimacum Creek Basin and vicinity, Jefferson County, Washington: a supplement to Scientific Investigations Report 2013-5160

USGS Publications Warehouse

Jones, Joseph L.; Johnson, Kenneth H.

2013-01-01

A steady-state groundwater-flow model described in Scientific Investigations Report 2013-5160, ”Numerical Simulation of the Groundwater-Flow System in Chimacum Creek Basin and Vicinity, Jefferson County, Washington” was developed to evaluate potential future impacts of growth and of water-management strategies on water resources in the Chimacum Creek Basin. This supplement to that report describes the unsuccessful attempt to perform a calibration to transient conditions on the model. The modeled area is about 64 square miles on the Olympic Peninsula in northeastern Jefferson County, Washington. The geologic setting for the model area is that of unconsolidated deposits of glacial and interglacial origin typical of the Puget Sound Lowlands. The hydrogeologic units representing aquifers are Upper Aquifer (UA, roughly corresponding to recessional outwash) and Lower Aquifer (LA, roughly corresponding to advance outwash). Recharge from precipitation is the dominant source of water to the aquifer system; discharge is primarily to marine waters below sea level and to Chimacum Creek and its tributaries. The model is comprised of a grid of 245 columns and 313 rows; cells are a uniform 200 feet per side. There are six model layers, each representing one hydrogeologic unit: (1) Upper Confining unit (UC); (2) Upper Aquifer unit (UA); (3) Middle Confining unit (MC); (4) Lower Aquifer unit (LA); (5) Lower Confining unit (LC); and (6) Bedrock unit (OE). The transient simulation period (October 1994–September 2009) was divided into 180 monthly stress periods to represent temporal variations in recharge, discharge, and storage. An attempt to calibrate the model to transient conditions was unsuccessful due to instabilities stemming from oscillations in groundwater discharge to and recharge from streamflow in Chimacum Creek. The model as calibrated to transient conditions has mean residuals and standard errors of 0.06 ft ±0.45 feet for groundwater levels and 0.48 ± 0.06 cubic

The photoproduction of ω mesons off the proton has been studied in the reaction γ p →p ω using the CEBAF Large Acceptance Spectrometer (CLAS) and the frozen-spin target in Hall B at the Thomas Jefferson National Accelerator Facility. For the first time, the target asymmetry T has been measured in photoproduction from the decay ω →π+π-π0 , using a transversely polarized target with energies ranging from just above the reaction threshold up to 2.8 GeV. Significant nonzero values are observed for these asymmetries, reaching about 30-40% in the third-resonance region. New measurements for the photon-beam asymmetry Σ are also presented, which agree well with previous CLAS results and extend the world database up to 2.1 GeV. These data and additional ω photoproduction observables from CLAS were included in a partial-wave analysis within the Bonn-Gatchina framework. Significant contributions from s -channel resonance production were found in addition to t -channel exchange processes.

The Ralston Buttes district in Jefferson County is one of the most significant new uranium districts located east of the Continental Divide in Colorado. The district is east of the Colorado Front Range mineral belt, along the east front of the range. From November 1953 through October 1956, about 10,000 tons of uranium ore, much of which was high-grade pitchblende-bearing vein material, was shipped from the district. The ore occurs in deposits that range in size from bodies containing less than 50 tons to ore shoots containing over 1,000 tons. The only other mining activity in the area has been a sporadic production of beryl, feldspar, and scrap mica from Precambrian pegmatites, and quarrying of dimension stone, limestone, and clay from sedimentary rocks. Most of the Ralston Buttes district consists of complexly folded Precambrian metamorphic and igneous rocks - gneiss, schist, quartzite, amphibolite, and granodiorite. Paleozoic and Mesozoic sedimentary rocks crop out in the northeastern part of the district. These rocks are cut by northwesterly-trending fault systems of Laramide age and by small bodies of intrusive rocks that are Tertiary in age. The typical uranium deposits in the district are hydrothermal veins occupying openings in Laramide fault breccias or related fractures that cut the Precambrian rocks. Pitchblende and lesser amounts of secondary uranium minerals are associated with sparse base-mental sulfides in a gangue of carbonate minerals, potash feldspar, and, more rarely, quartz. Less common types of deposits consist of pitchblende and secondary uranium minerals that occupy fractures cutting pegmatites and quartz veins. The uranium deposits are concentrated in two areas, the Ralston Creek area and the Golden Gate Canyon area. The deposits in the Ralston Creek area are located along the Rogers fault system, and the deposits in the Golden Gate Canyon area are along the Hurricane Hill fault system. Two geologic factors were important to the localization

This report presents information used to characterize the groundwater flow system in the Chimacum Creek basin. It includes descriptions of the geology and hydrogeologic framework; groundwater recharge and discharge; groundwater levels and flow directions; seasonal fluctuations in groundwater level; interactions between aquifers and the surface-water system; and a groundwater budget. The study area covers 124 square miles in northeastern Jefferson County, Washington, and includes the Chimacum Creek basin, which drains an area of about 37 square miles. The area is underlain by a north-thickening sequence of unconsolidated glacial and interglacial deposits that overlie sedimentary and igneous bedrock units that crop out along the margins and western interior of the study area. Six hydrogeologic units consisting of unconsolidated aquifers and confining units, along with an underlying bedrock unit, were identified. A surficial hydrogeologic map was developed and used with well information from 187 drillers' logs to construct 4 hydrogeologic sections, and maps showing the extent and thickness of the units. Natural recharge was estimated using precipitation-recharge relation regression equations developed for western Washington, and estimates were calculated for return flow from data on domestic indoor and outdoor use and irrigated agriculture. Results from synoptic streamflow measurements and water table elevations determined from monthly measurements at monitoring wells are presented and compared with those from a study conducted during 2002-03. A water budget was calculated comprising long-term average recharge, domestic public-supply withdrawals and return flow, self-supplied domestic withdrawals and return flow, and irrigated agricultural withdrawals and return flow.

Deep Exclusive Pseudoscalar Meson Production at Jefferson Lab Hall C

Measurements of exclusive meson production are a useful tool in the study of hadronic structure. In particular, one can discern the relevant degrees of freedom at different distance scales through these studies. In the transition region between low momentum transfer (where a description of hadronic degrees of freedom in terms of effective hadronic Lagrangians is valid) and high momentum transfer (where the degrees of freedom are quarks and gluons), the predictive power of Quantum Chromodynamics (QCD), the theory of the strong interaction, is limited due to the absence of a complete solution. Thus, one has to rely upon experimental datamore » from the non-perturbative intermediate-energy regime to thoroughly understand the onset of perturbative QCD (pQCD) as the momentum transfer is increased. This work involves two deep exclusive meson electroproduction experiments at Jefferson Lab (JLab). The p(e,e'pi+)n reaction is studied at fixed Q^2 and W of 2.5 GeV2 and 2.0 GeV, respectively, while varying the four momentum transfer to the nucleon -t from 0.2 to 2.1 GeV2 . As -t is increased, the hadronic interaction scale is reduced independently of the observation scale of the virtual photon, providing valuable information about the hard- scattering process in general. The data was taken at JLab Hall C in 2003, as a part of the experiment E01-004, Fpi-2, using the High Momentum Spectrometer (HMS) and Short Orbit Spectrometer (SOS), and in this work, the results of the differential cross section analysis are presented and compared to prior data, as well as two theoretical models. Using these results over a wide -t range, the transition from hard to soft QCD is also studied. In addition, the p(e,e'K+)Lambda(Sigma0) reactions are also studied. Despite their importance in elucidating the reaction mechanism underlying strangeness production, we still do not have complete understanding of these reactions above the resonance region. The experiment, E12- 09-011, intends to

A groundwater-flow model was developed to evaluate potential future effects of growth and of water-management strategies on water resources in the Chimacum Creek Basin. The model covers an area of about 64 square miles (mi2) on the Olympic Peninsula in northeastern Jefferson County, Washington. The Chimacum Creek Basin drains an area of about 53 mi2 and consists of Chimacum Creek and its tributary East Fork Chimacum Creek, which converge near the town of Chimacum and discharge to Port Townsend Bay near the town of Irondale. The topography of the model area consists of north-south oriented, narrow, regularly spaced parallel ridges and valleys that are characteristic of fluted glaciated surfaces. Thick accumulations of peat occur along the axis of East Fork Chimacum Creek and provide rich soils for agricultural use. The study area is underlain by a north-thickening sequence of unconsolidated glacial (till and outwash) and interglacial (fluvial and lacustrine) deposits, and sedimentary and igneous bedrock units that crop out along the margins and the western interior of the model area. Six hydrogeologic units in the model area form the basis of the groundwater-flow model. They are represented by model layers UC (upper confining), UA (upper aquifer), MC (middle confining), LA (lower aquifer), LC (lower confining), and OE (bedrock). Groundwater flow in the Chimacum Creek Basin and vicinity was simulated using the groundwater-flow model, MODFLOW-2005. The finite-difference model grid comprises 245 columns, 313 rows, and 6 layers. Each model cell has a horizontal dimension of 200 × 200 feet (ft). The thickness of model layers varies throughout the model area and ranges from 5 ft in the non-bedrock units to more than 2,400 ft in the bedrock. Groundwater flow was simulated for steady-state conditions, which were simulated for calibration of the model using average recharge, discharge, and water levels for the 180-month period October 1994–September 2009. The model as

We examined individual, household, and neighborhood correlates of intimate partner violence (IPV) before and during pregnancy. We used multilevel modeling to investigate IPV among 2887 pregnant women in 112 census tracts who sought prenatal care in 8 public clinics in Jefferson County, Alabama, from 1997 through 2001. Data were collected from the Perinatal Emphasis Research Center project, the 2000 Census, and the local Sheriff and Police Departments Uniform Crime Reports for 1997 through 2001. Participants were predominantly young, African American, on Medicaid, and residents of low-income neighborhoods. The prevalence of past-year male partner-perpetrated physical or sexual violence was 7.4%. Neighborhood residential stability, women performing most of the housework (lack of involvement among partners), being unmarried (being in an uncommitted relationship), and alcohol use were positively associated with elevated IPV risk. Significant protective factors for IPV included older age at first vaginal intercourse and a greater sense of mastery (e.g., the perception of oneself as an effective person). Both neighborhood contextual and individual and household compositional effects are associated with IPV among low-income pregnant women. The results imply that combined interventions to improve neighborhood conditions and strengthen families may effectively reduce IPV.

Effects of Jefferson Road stormwater-detention basin on loads and concentrations of selected chemical constituents in East Branch of Allen Creek at Pittsford, Monroe County, New York

2004-01-01

Discharge and water-quality data collection at East Branch Allen Creek from 1990 through 2000 provide a basis for estimating the effect of the Jefferson Road detention basin on loads and concentrations of chemical constituents downstream from the basin. Mean monthly flow for the 5 years prior to construction of the detention basin (8.71 ft3/s) was slightly lower than after (9.08 ft3/s). The slightly higher mean monthly flow after basin construction may have been influenced by the peak flow for the period of record that occurred in July 1998 or variations in flow diverted from the canal. No statistically significant difference in average monthly mean flow before and after basin installation was indicated.Total phosphorus was the only constituent to show no months with significant differences in load after basin construction. Several constituents showed months with significantly smaller loads after basin construction than before, whereas some constituents showed certain months with smaller and some months with greater loads, after basin construction. Statistical analysis of the "mean monthly load" for all months before and all months after construction of the detention basin showed only one constituent (ammonia + organic nitrogen) with a significantly lower load after construction and none with higher loads.Median concentrations of ammonia + organic nitrogen showed a statistically significant decrease (from 0.78 mg/L to 0.60 mg/L) after basin installation, as did nitrite + nitrate (from 1.50 mg/L to 0.96 mg/L); in contrast, the median concentration of dissolved chloride increased from 95.5 mg/L before basin installation to 109 mg/L thereafter. A trend analysis of constituent concentrations before and after installation of the detention basin showed that total phosphorus had a downward trend after installation.Analysis of the data collected at East Branch Allen Creek indicates that the Jefferson Road detention basin, in some cases, provides an improvement (reduction

: On December 7, 1941, the Sunday-morning quiet of the U.S. naval base in Pearl Harbor, Hawaii, was shattered by dive-bombing Japanese fighter planes. The planes came in two waves-and when it was all over, more than 2,400 were killed and more than 1,100 were injured.Nurses were stationed at U.S. Naval Hospital Pearl Harbor, Tripler General Hospital (now Tripler Army Medical Center), Hickam Field Hospital, Schofield Barracks Station Hospital, and aboard the USS Solace, and witnessed the devastation. But they also did what nurses do in emergencies-they responded and provided care to those in need. Here are the stories of a few of those nurses.

The ability of health-care providers to demonstrate empathy toward their patients results in a number of positive outcomes improving the quality of care. In addition, a provider's level of emotional intelligence (EI) can further the doctor-patient relationship, stimulating a more personalized and comprehensive manner of treating patients. Furthermore, personality traits of a clinician may positively or negatively influence that relationship, as well as clinical outcomes. This study was designed to evaluate empathy levels in podiatric medical students in a 4-year doctoral program. Moreover, this study aimed to determine whether EI, personality traits, and demographic variables exhibit correlations with the observed empathy patterns. This cross-sectional study collected data using an anonymous web-based survey completed by 150 students registered at the New York College of Podiatric Medicine. There were four survey sections: (1) demographics, (2) empathy (measured by the Jefferson Scale of Physicians' Empathy), (3) EI (measured by the Assessing Emotions Scale), and (4) personality traits (measured by the NEO-Five-Factor Inventory-3). Empathy levels were significantly correlated with EI scores (r = 0.62, n = 150, P< 0.0001). All the five domains of personality were also shown to correlate with empathy scores, as well as with EI scores. With respect to demographics, Asian-American students had lower mean empathy scores than students of other races (P = 0.0018), females had higher mean empathy scores compared to men (P = 0.001), and undergraduate grade point average correlated with empathy scores in a nonmonotonic fashion (P = 0.0269). When measuring the variables, it was evident that there was a strong correlation between empathy, EI, and personality in podiatric medical students. Given the suggested importance and effect of such qualities on patient care, these findings may serve as guidance for possible amendments and warranted curriculum initiatives in medical

To assess whether favourable perceptions of the learning environment (LE) were associated with better quality of life, less burnout and more empathy across three undergraduate medical education programmes in Israel, Malaysia and China. Cross-sectional surveys were administered at the end of the 2013-2014 academic year at three medical schools: Technion American Medical Students Program (TAMS) in Israel, Perdana University-Royal College of Surgeons in Ireland School of Medicine (PURCSI) in Malaysia and Peking Union Medical College (PUMC) in China. LE perceptions were assessed using the Johns Hopkins Learning Environment Scale (JHLES). Well-being was assessed using validated items for quality of life and the depersonalisation and emotional exhaustion domains of burnout. The 20-item Jefferson Empathy Scale assessed empathy. Statistical analyses included bivariate regressions and multivariate regressions that adjusted for gender, school, class year and perceived academic rank. Overall, 400/622 (64.3%) students responded, with the following rates by site: TAMS 92/121 (76.0%), PURCSI 160/198 (80.1%) and PUMC 148/303 (48.8%). In multivariate models, favourable overall LE perceptions were associated with higher odds of good quality of life (odds ratio [OR], 3.2; 95% confidence interval [CI], 1.8-5.8; p < 0.001) and lower odds of emotional exhaustion (OR, 0.34; 95% CI, 0.24-0.50; p < 0.001) and depersonaliation (OR, 0.30; 95% CI, 0.24-0.37; p = 0.001). 'Community of Peers', one of seven factors in the JHLES, was the only one to be independently associated with better quality of life and less emotional exhaustion and depersonalisation. After adjusting for covariates, there was not a statistically significant association between overall LE and empathy (OR, 1.4; 95% CI, 0.91-2.2; p = 0.12). Students' LE perceptions are closely associated with their well-being, and fostering peer community may hold promise for enhancing quality of life and protecting against burnout. Across

We present final results on the photon electroproduction (more » $$\\vec{e}p\\rightarrow ep\\gamma$$) cross section in the deeply virtual Compton scattering (DVCS) regime and the valence quark region from Jefferson Lab experiment E00-110. Results from an analysis of a subset of these data were published before, but the analysis has been improved which is described here at length, together with details on the experimental setup. Furthermore, additional data have been analyzed resulting in photon electroproduction cross sections at new kinematic settings, for a total of 588 experimental bins. Results of the $Q^2$- and $$x_B$$-dependences of both the helicity-dependent and helicity-independent cross sections are discussed. The $Q^2$-dependence illustrates the dominance of the twist-2 handbag amplitude in the kinematics of the experiment, as previously noted. Thanks to the excellent accuracy of this high luminosity experiment, it becomes clear that the unpolarized cross section shows a significant deviation from the Bethe-Heitler process in our kinematics, compatible with a large contribution from the leading twist-2 DVCS$^2$ term to the photon electroproduction cross section. The necessity to include higher-twist corrections in order to fully reproduce the shape of the data is also discussed. The DVCS cross sections in this study represent the final set of experimental results from E00-110, superseding the previous publication.« less

At the Thomas Jefferson National Accelerator Facility (JLab) a research and development project for a Detector of Internally-Reflected Cherenkov light for the upcoming Electron Ion Collider is underway. One goal is the development of a compact readout camera that can operate in high magnetic fields. Small-size photon sensors, such as Microchannel-Plate Photomultipliers (MCP-PMT), are key components of the readout. Here we present our work to set up and commission a dedicated test facility at JLab where MCP-PMT gain is evaluated in magnetic fields of up to 5 T, and to develop a test procedure and analysis software to determine the gain. We operate the setup in a single-photon mode, where a light-emitting diode delivers photons to the sensor's photocathode. The PMT spectrum is measured with a flash Analog-to-Digital converter (fADC). We model the spectrum as a sum of an exponential background and a convolution of Poisson and Gaussian distributions of the pedestal and multiple photoelectron peaks, respectively. We determine the PMT's gain from the position of the single-photoelectron peak obtained by fitting the fADC spectrum to the model. Our gain uncertainty is <10%. The facility is now established and will have a long-lasting value for sensor tests and beyond-nuclear-physics applications.

The objective of this study was to assess biological colonization of wooden and brick buildings in the former Auschwitz II-Birkenau concentration camp, and to identify the organisms colonizing the examined buildings. Microbiological analysis did not reveal increased microbial activity, and the total microbial count of the barrack surfaces did not exceed 10 3  CFU/100 cm 2 . However, certain symptoms of biodegradation of the buildings were observed. The predominant microflora consisted of bacteria of the genera Bacillus , Sporosarcina , Pseudomonas , Micrococcus , Streptomyces , and Staphylococcus , as well as fungi of the genera Acremonium , Cladosporium , Alternaria , Humicola , Penicillium , and Chaetomium . The microflora patterns varied both in wooden and brick buildings. The structural elements of wooden and brick barracks, and especially of the floors and lower parts of bathroom walls, were infected by cyanobacteria and algae, with the most numerous being cyanobacteria of the genera Scytonema , Chroococcus , Gloeothece , Leptolyngbya , diatoms of the genus Diadesmis , and chlorophytes of the genera Chlorella and Apatococcus . The outer surfaces of the examined buildings were primarily colonized by lichens and bryophytes, with nearly 30 species identified. The dominant species of lichens belonged to the genera Candelariella , Caloplaca , Lecanora , Lecidea , Lepraria , Physcia , and Protoparmeliopsis , and those of bryophytes to the genera Bryum , Ceratodon , Marchantia , and Tortula . The quantity and species diversity of lichens and mosses were much lower in wooden barracks than in brick ones. The external surfaces of those barracks were only affected by Lecanora conizaeoides , Lecanora symmicta , Lepraria cf. incana , and Strangospora pinicola . The study results revealed vast biodiversity among the species colonizing historic buildings. The presence of these groups of organisms, resulting from their natural expansion in the environment, is undesirable

Hurricane Maria, 2017 Hydrographic Response for Puerto Rico and U.S. Virgin Islands by the NOAA Ship Thomas Jefferson

After many coastal natural disasters, ports and harbors must be surveyed for navigation dangers, cleared, and opened as quickly as possible to facilitate recovery and reconstruction. The appropriate survey asset to use varies by location and condition. Routinely, hydrographic response to a natural disaster is conducted by survey teams with trailer-hitched vessels deployed quickly by land. This was the case for Hurricanes Harvey, Irma and Nate which struck mainland U.S. In the U.S. territories of Puerto Rico and the Virgin Islands post-Hurricane Maria, however, the devastation to the regional infrastructure resulted in a dearth of adequate accommodations, fuel, security and passable roads required to support a land-based response. On September 24th, 2017, NOAA Ship Thomas Jefferson (TJ), a 208-foot-long hydrographic survey vessel with a 38-person complement and two 28-foot-long survey launches, began an uninterrupted 20-day cruise to survey major ports around the islands. The ship's crew acquired high-resolution multibeam echo sounder (MBES) and concurrent object-detection side scan sonar (SSS) in and around 18 individual port facilities in 13 areas. The TJ is the appropriate platform for sustained remote response due to a self-contained infrastructure that supports deployment and recovery of survey launches, as well as 24/7 data processing facilities. The TJ crew produced digital terrain models and SSS mosaics, in addition to developing new reports on specific hazards overnight. These products quickly informed responders, stakeholders and responsible authorities about the efficacy of waterways.

John Young Templeton III was born in 1917 in Portsmouth, Virginia, and graduated from Jefferson Medical College in 1941. He completed his residency training under Dr. John H. Gibbon, Jr., and was the first resident who worked on Gibbon's heart-lung machine. After his training, he remained at Jefferson as an American Cancer Society fellow and Damon Runyon fellow and went on to become the fourth Samuel D. Gross Professor and Chair of the Department of Surgery in 1967. Dr. Templeton was the recipient of numerous grants and published over 80 papers in the field of cardiothoracic surgery. As a teacher and mentor, he was a beloved figure who placed great faith in his residents. He participated in over 60 professional societies, serving as president to many such as the Philadelphia Academy of Surgery and the Pennsylvania Association of Thoracic Surgery. He was also recognized through his many awards, in particular the John Y. Templeton III lectureship established in 1980 at Jefferson of whom Denton Cooley was the first lecturer. Dr. Templeton retired from practice in 1987. He is forever remembered as an important model of a modern surgeon evident in numerous academic achievements, the admiration and affection of his trainees, and the lives of patients that he had touched.

Continuous hydrologic simulation of runoff for the Middle Fork and South Fork of the Beargrass Creek basin in Jefferson County, Kentucky

The Hydrological Simulation Pro-gram-FORTRAN (HSPF) was applied to an urban drainage basin in Jefferson County, Ky to integrate the large amounts of information being collected on water quantity and quality into an analytical framework that could be used as a management and planning tool. Hydrologic response units were developed using geographic data and a K-means analysis to characterize important hydrologic and physical factors in the basin. The Hydrological Simulation Program FORTRAN Expert System (HSPEXP) was used to calibrate the model parameters for the Middle Fork Beargrass Creek Basin for 3 years (June 1, 1991, to May 31, 1994) of 5-minute streamflow and precipitation time series, and 3 years of hourly pan-evaporation time series. The calibrated model parameters were applied to the South Fork Beargrass Creek Basin for confirmation. The model confirmation results indicated that the model simulated the system within acceptable tolerances. The coefficient of determination and coefficient of model-fit efficiency between simulated and observed daily flows were 0.91 and 0.82, respectively, for model calibration and 0.88 and 0.77, respectively, for model confirmation. The model is most sensitive to estimates of the area of effective impervious land in the basin; the spatial distribution of rain-fall; and the lower-zone evapotranspiration, lower-zone nominal storage, and infiltration-capacity parameters during recession and low-flow periods. The error contribution from these sources varies with season and antecedent conditions.

Field Work Proposal: PUBLIC OUTREACH EVENT FOR ACCELERATOR STEWARDSHIP TEST FACILITY PILOT PROGRAM

Hutton, Andrew; Areti, Hari

2015-03-05

Jefferson Lab’s outreach efforts towards the goals of Accelerator Stewardship Test Facility Pilot Program consist of the lab’s efforts in three venues. The first venue, at the end of March is to meet with the members of Virginia Tech Corporate Research Center (VTCRC) (http://www.vtcrc.com/tenant-directory/) in Blacksburg, Virginia. Of the nearly 160 members, we expect that many engineering companies (including mechanical, electrical, bio, software) will be present. To this group, we will describe the capabilities of Jefferson Lab’s accelerator infrastructure. The description will include not only the facilities but also the intellectual expertise. No funding is requested for this effort. Themore » second venue is to reach the industrial exhibitors at the 6th International Particle Accelerator Conference (IPAC’15). Jefferson Lab will host a booth at the conference to reach out to the >75 industrial exhibitors (https://www.jlab.org/conferences/ipac2015/SponsorsExhibitors.php) who represent a wide range of technologies. A number of these industries could benefit if they can access Jefferson Lab’s accelerator infrastructure. In addition to the booth, where written material will be available, we plan to arrange a session A/V presentation to the industry exhibitors. The booth will be hosted by Jefferson Lab’s Public Relations staff, assisted on a rotating basis by the lab’s scientists and engineers. The budget with IPAC’15 designations represents the request for funds for this effort. The third venue is the gathering of Southeastern Universities Research Association (SURA) university presidents. Here we plan to reach the research departments of the universities who can benefit by availing themselves to the infrastructure (material sciences, engineering, medical schools, material sciences, to name a few). Funding is requested to allow for attendance at the SURA Board Meeting. We are coordinating with DOE regarding these costs to raise the projected
