A sub- to super-ambient temperature programmable microfabricated gas chromatography column enables more efficient chemical separation of chemical analytes in a gas mixture by combining a thermoelectric cooler and temperature sensing on the microfabricated column. Sub-ambient temperature programming enables the efficient separation of volatile organic compounds and super-ambient temperature programming enables the elution of less volatile analytes within a reasonable time. The small heat capacity and thermal isolation of the microfabricated column improves the thermal time response and power consumption, both important factors for portable microanalytical systems.

Three separate fire test programmes exposing casks beyond the regulatory thermal test requirements were performed by Sandia National Laboratories during the late 1970s and mid 1980s. The results of these test programmes can be used to assist in addressing the adequacy of the regulatory thermal test of fully engulfing exposure at 800°C for 30 min and how that test might relate to real accident thermal environments. The test programmes were undertaken on obsolete and new casks on behalf of the US Department of Energy (DOE), the US Department of Transportation (DOT) and the Japanese Power Reactor and Nuclear Fuel Developmentmore » Corporation (PNC), currently known as the Japan Atomic Energy Agency. Two of the tests involved exposure of casks in damaged transport vehicles to fully engulfing fires for 72–125 min, and the other test involved four exposures of a cask to torch environments for 30 min. Much of the original documentation regarding these tests and their results is no longer readily available. The documents relating to these tests have been surveyed; this paper presents summaries from this survey of the tests and their results. Specifically, for the pool fire exposures, the temperatures measured in the flames of both exceeded the flame temperature required by the Transport Regulations; yet an obsolete 67 t cask endured 90 min of exposure before evidence of failure was detected, and a new cask endured the 72 min exposure while retaining its containment integrity. For the exposure of a modified obsolete cask to four different torch environments, the integrity of the cask was retained and the relative temperature increases within the cask were well within acceptable limits and well below the values that could be expected if the cask was exposed to the regulatory thermal test. In this paper, a review of these three thermal test programmes, establishes that the two older cask designs and one new cask design have the ability to survive environments that were different from (the torch environments) or more severe than the environment specified by the existing thermal test requirement in the Transport Regulations. Finally, these results can be extrapolated to apply to modern casks that generally have more robust designs as well as better quality assurance applied during the manufacturing process.« less

Oren, J. A.; Williams, D. R.

1973-01-01

Fluid flow analysis, special thermal analysis and input/output capabilities of the MOTAR routine were incorporated into the SINDA routine. All the capabilities were added in the form of user subroutines so that they may be added to different versions of SINDA with a minimum of programmer effort. Two modifications were made to the existing subroutines of SINDA/8 to incorporate the above subroutines. These were: (1) A modification to the preprocessor to permit actual values of array numbers, conductor numbers, node numbers or constant numbers supplied as array data to be converted to relative numbers. (2) Modifications to execution subroutine CNFAST to make it compatible with the radiant interchange user subroutine, RADIR. This modified version of SINDA has been designated SINDA/version 9. A detailed discussion of the methods used for the capabilities added is presented. The modifications for the SINDA subroutines are described, as well as user subroutines. All subroutines added or modified are listed.

This article establishes an alternative method for the characterization of volatiles organic matter (VOM) contained in deposits of the piston first ring grooves of diesel engines using a ChromatoProbe direct sample introduction (DSI) device coupled to gas chromatography/mass spectrometry (GC/MS) analysis. The addition of an organic solvent during thermal desorption leads to an efficient extraction and a good chromatographic separation of extracted products. The method was optimized investigating the effects of several solvents, the volume added to the solid sample, and temperature programming of the ChromatoProbe DSI device. The best results for thermal desorption were found using toluene as an extraction solvent and heating the programmable temperature injector from room temperature to 300 degrees C with a temperature step of 105 degrees C. With the use of the optimized thermal desorption conditions, several components have been positively identified in the volatile fraction of the deposits: aromatics, antioxidants, and antioxidant degradation products. Moreover, this work highlighted the presence of diesel fuel in the VOM of the piston deposits and gave new facts on the absence of the role of diesel fuel in the deposit formation process. Most importantly, it opens the possibility of quickly performing the analysis of deposits with small amounts of samples while having a good separation of the volatiles.

Adopting good nodalization strategy is essential to produce an accurate and high quality input model for Deterministic Safety Analysis (DSA) using System Thermal-Hydraulic (SYS-TH) computer code. The purpose of such analysis is to demonstrate the compliance against regulatory requirements and to verify the behavior of the reactor during normal and accident conditions as it was originally designed. Numerous studies in the past have been devoted to the development of the nodalization strategy for small research reactor (e.g. 250kW) up to the bigger research reactor (e.g. 30MW). As such, this paper aims to discuss the state-of-arts thermal hydraulics channel to be employed in the nodalization for RTP-TRIGA Research Reactor specifically for the reactor core. At present, the required thermal-hydraulic parameters for reactor core, such as core geometrical data (length, coolant flow area, hydraulic diameters, and axial power profile) and material properties (including the UZrH1.6, stainless steel clad, graphite reflector) have been collected, analyzed and consolidated in the Reference Database of RTP using standardized methodology, mainly derived from the available technical documentations. Based on the available information in the database, assumptions made on the nodalization approach and calculations performed will be discussed and presented. The development and identification of the thermal hydraulics channel for the reactor core will be implemented during the SYS-TH calculation using RELAP5-3D® computer code. This activity presented in this paper is part of the development of overall nodalization description for RTP-TRIGA Research Reactor under the IAEA Norwegian Extra-Budgetary Programme (NOKEBP) mentoring project on Expertise Development through the Analysis of Reactor Thermal-Hydraulics for Malaysia, denoted as EARTH-M.

Hydrogels are important in biological and medical applications, such as drug delivery and tissue engineering. DNA hydrogels have attracted significant attention due to the programmability and biocompatibility of the material. We developed a series of low-cost one-strand DNA hydrogels self-assembled from single-stranded DNA monomers containing multiple palindromic domains. This new hydrogel design is simple and programmable. Thermal stability, mechanical properties, and loading capacity of these one-strand DNA hydrogels can be readily regulated by simply adjusting the DNA domains. © 2016 WILEY-VCH Verlag GmbH & Co.

1979-01-01

A computer program to calculate transient and steady state temperatures, pressures, and coolant flows in a cooled axial flow turbine blade or vane with an impingement insert is described. Coolant-side heat transfer coefficients are calculated internally in the program, with the user specifying either impingement or convection heat transfer at each internal flow station. Spent impingement air flows in a chordwise direction and is discharged through the trailing edge and through film cooling holes. The ability of the program to handle film cooling is limited by the internal flow model. Input to the program includes a description of the blade geometry, coolant-supply conditions, outside thermal boundary conditions, and wheel speed. The blade wall can have two layers of different materials, such as a ceramic thermal barrier coating over a metallic substrate. Program output includes the temperature at each node, the coolant pressures and flow rates, and the coolant-side heat transfer coefficients.

Modelling cost-effectiveness of different vasectomy methods in India, Kenya, and Mexico.

Vasectomy is generally considered a safe and effective method of permanent contraception. The historical effectiveness of vasectomy has been questioned by recent research results indicating that the most commonly used method of vasectomy--simple ligation and excision (L and E)--appears to have a relatively high failure rate, with reported pregnancy rates as high as 4%. Updated methods such as fascial interposition (FI) and thermal cautery can lower the rate of failure but may require additional financial investments and may not be appropriate for low-resource clinics. In order to better compare the cost-effectiveness of these different vasectomy methods, we modelled the costs of different vasectomy methods using cost data collected in India, Kenya, and Mexico and effectiveness data from the latest published research. The costs associated with providing vasectomies were determined in each country through interviews with clinic staff. Costs collected were economic, direct, programme costs of fixed vasectomy services but did not include large capital expenses or general recurrent costs for the health care facility. Estimates of the time required to provide service were gained through interviews and training costs were based on the total costs of vasectomy training programmes in each country. Effectiveness data were obtained from recent published studies and comparative cost-effectiveness was determined using cost per couple years of protection (CYP). In each country, the labour to provide the vasectomy and follow-up services accounts for the greatest portion of the overall cost. Because each country almost exclusively used one vasectomy method at all of the clinics included in the study, we modelled costs based on the additional material, labour, and training costs required in each country. Using a model of a robust vasectomy program, more effective methods such as FI and thermal cautery reduce the cost per CYP of a vasectomy by $0.08-$0.55. Based on the results presented, more effective methods of vasectomy--including FI, thermal cautery, and thermal cautery combined with FI--are more cost-effective than L and E alone. Analysis shows that for a programme in which a minimum of 20 clients undergo vasectomies per month, the cost per CYP is reduced in all three countries by updated vasectomy methods.

The development of a direct analysis in real time-mass spectrometry (DART-MS) method and first prototype vaporizer for the detection of low molecular weight (∼30-100 Da) contaminants representative of those detected in water samples from the International Space Station is reported. A temperature-programmable, electro-thermal vaporizer (ETV) was designed, constructed, and evaluated as a sampling interface for DART-MS. The ETV facilitates analysis of water samples with minimum user intervention while maximizing analytical sensitivity and sample throughput. The integrated DART-ETV-MS methodology was evaluated in both positive and negative ion modes to (1) determine experimental conditions suitable for coupling DART with ETV as a sample inlet and ionization platform for time-of-flight MS, (2) to identify analyte response ions, (3) to determine the detection limit and dynamic range for target analyte measurement, and (4) to determine the reproducibility of measurements made with the method when using manual sample introduction into the vaporizer. Nitrogen was used as the DART working gas, and the target analytes chosen for the study were ethyl acetate, acetone, acetaldehyde, ethanol, ethylene glycol, dimethylsilanediol, formaldehyde, isopropanol, methanol, methylethyl ketone, methylsulfone, propylene glycol, and trimethylsilanol.

We propose and demonstrate a silicon-on-insulator (SOI) on-chip programmable filter based on a four-tap finite impulse response structure. The photonic filter is programmable thanks to amplitude and phase modulation of each tap controlled by thermal heaters. We further demonstrate the tunability of the filter central wavelength, bandwidth and variable passband shape. The tuning range of the central wavelength is at least 42% of the free spectral range. The bandwidth tuning range is at least half of the free spectral range. Our scheme has distinct advantages of compactness, capability for integrating with electronics.

The Multi-Purpose Logistics Module (MPLM) is the primary carrier for "pressurized" logistics to and from the International Space Station (ISS). The MPLM is transported in the payload bay of the Space Shuttle and is docked to the ISS for unloading, and reloading, of contents within the ISS shirt sleeve environment. Foil heaters, controlled originally with bi-metallic thermostats, are distributed across the outside of the MPLM structure and are utilized to provide energy to the structure to avoid exposure to cold temperatures and prevent condensation. The existing bi-metallic, fixed temperature set point thermostats have been replaced with Programmable Thermostats Modules (PTMs) in the Passive Thermal Control Subsystem (PTCS) 28Vdc shell heater circuits. The goal of using the PTM thermostat is to improve operational efficiency of the MPLM on-orbit shell heaters by providing better shell temperature control via feedback control capability. Each heater circuit contains a programmable thermostat connected to an external temperature sensor, a Resistive Temperature Device (RTD), which is used to provide continuous temperature monitoring capability. Each thermostat has programmable temperature set points and control spans. The data acquisition system uses a standard RS-485 serial interface communications cable to provide digital control capability. The PTM system was designed by MSFC, relying upon ALTEC support for their integration within the MPLM system design, while KSC performed the installation and ground checkout testing of the thermostat and RS-485 communication cable on the MPLM FM1 flight module. The PTMs were used for the first time during the STS-121/ULF1.1 mission. This paper will describe the design, development and verification of the PTM system, as well as the PTM flight performance and comparisons with SINDA thermal model predictions.

Climatic aging experiments were conducted on two types of outdoor polymer insulators by using a programmable weather-ometer. The housing materials for the insulators were silicone rubber (SR) and ethylene propylene diene monomer (EPDM). The accelerated aging stresses were comprised of ultraviolet radiation, elevated temperature, temperature cycling, thermal shock and high humidity. Their effects on the insulator surface conditions and electrical performance wee examined through visual inspection and SEM studies, contact angle measurements, thermogravimetric analysis (TGA), energy dispersive spectroscopy (EDS) analysis, and 50% impulse flashover voltage tests. The results showed a significant damage on the insulator surface caused by some ofmore » the imposed aging stresses. The EDS analysis suggested a photooxidation process that happened on the insulator surface during the aging period.« less

The presence of micropollutants in the aquatic environment is a worldwide environmental concern. The diversity of micropollutants and the low concentration levels at which they may occur in the aquatic environment have greatly complicated the analysis and detection of these chemicals. Two sorptive extraction samplers and two thermal desorption methods for the detection of micropollutants in water were compared. A low-cost, disposable, in-house made sorptive extraction sampler was compared to SBSE using a commercial Twister sorptive sampler. Both samplers consisted of polydimethylsiloxane (PDMS) as a sorptive medium to concentrate micropollutants. Direct thermal desorption of the disposable samplers in the inlet of a GC was compared to conventional thermal desorption using a commercial thermal desorber system (TDS). Comprehensive gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS) was used for compound separation and identification. Ten micropollutants, representing a range of heterogeneous compounds, were selected to evaluate the performance of the methods. The in-house constructed sampler, with its associated benefits of low-cost and disposability, gave results comparable to commercial SBSE. Direct thermal desorption of the disposable sampler in the inlet of a GC eliminated the need for expensive consumable cryogenics and total analysis time was greatly reduced as a lengthy desorption temperature programme was not required. Limits of detection for the methods ranged from 0.0010 ng L -1 to 0.19 ng L -1 . For most compounds, the mean (n = 3) recoveries ranged from 85% to 129% and the % relative standard deviation (% RSD) ranged from 1% to 58% with the majority of the analytes having a %RSD of less than 30%.

In order to provide new furnace technology to accommodate microgravity research studies and commercial applications in material processes, research has been initiated on the development of the Programmable-Multi-zone Furnace (PMZF). The PMZF is described as a multi-user materials processing furnace facility that is composed of thirty or more heater elements in series on a muffle tube or in a stacked ring-type configuration and independently controlled by a computer. One of the aims of the PMZF project is to allow furnace thermal gradient profiles to be reconfigured without physical modification of the hardware by creating the capability of reconfiguring thermal profiles in response to investigators' requests. The future location of the PMZF facility is discussed; the preliminary science survey results and preliminary conceptual designs for the PMZF are presented; and a review of multi-zone furnace technology is given.

This paper discusses a student project at Kettering University focusing on the design and construction of an energy efficient greenhouse climate control system. In order to maintain acceptable temperatures and stabilize temperature fluctuations in a portable plastic greenhouse economically, a computer controlled climate control system was developed to capture and store thermal energy incident on the structure during daylight periods and release the stored thermal energy during dark periods. The thermal storage mass for the greenhouse system consisted of a water filled base unit. The heat exchanger consisted of a system of PVC tubing. The control system used a programmable LabView computer interface to meet functional specifications that minimized temperature fluctuations and recorded data during operation. The greenhouse was a portable sized unit with a 5' x 5' footprint. Control input sensors were temperature, water level, and humidity sensors and output control devices were fan actuating relays and water fill solenoid valves. A Graphical User Interface was developed to monitor the system, set control parameters, and to provide programmable data recording times and intervals.

The first generation of high performance thermal imaging sensors in the UK was based on two axis opto-mechanical scanning systems and small (4-16 element) arrays of the SPRITE detector, developed during the 1970s. Almost two decades later, a 2nd Generation system, STAIRS C was introduced, based on single axis scanning and a long linear array of approximately 3000 elements. The UK has now begun the industrialisation of 3 rd Generation High Performance Thermal Imaging under a programme known as "Albion". Three new high performance cadmium mercury telluride arrays are being manufactured. The CMT material is grown by MOVPE on low cost substrates and bump bonded to the silicon read out circuit (ROIC). To maintain low production costs, all three detectors are designed to fit with existing standard Integrated Detector Cooling Assemblies (IDCAs). The two largest focal planes are conventional devices operating in the MWIR and LWIR spectral bands. A smaller format LWIR device is also described which has a smart ROIC, enabling much longer stare times than are feasible with conventional pixel circuits, thus achieving very high sensitivity. A new reference surface technology for thermal imaging sensors is described, based on Negative Luminescence (NL), which offers several advantages over conventional peltier references, improving the quality of the Non-Uniformity Correction (NUC) algorithms.

The Computer Aided System Engineering and Analysis (CASE/A) Version 5.0 Programmer's Manual provides the programmer and user with information regarding the internal structure of the CASE/A 5.0 software system. CASE/A 5.0 is a trade study tool that provides modeling/simulation capabilities for analyzing environmental control and life support systems and active thermal control systems. CASE/A has been successfully used in studies such as the evaluation of carbon dioxide removal in the space station. CASE/A modeling provides a graphical and command-driven interface for the user. This interface allows the user to construct a model by placing equipment components in a graphical layout of the system hardware, then connect the components via flow streams and define their operating parameters. Once the equipment is placed, the simulation time and other control parameters can be set to run the simulation based on the model constructed. After completion of the simulation, graphical plots or text files can be obtained for evaluation of the simulation results over time. Additionally, users have the capability to control the simulation and extract information at various times in the simulation (e.g., control equipment operating parameters over the simulation time or extract plot data) by using "User Operations (OPS) Code." This OPS code is written in FORTRAN with a canned set of utility subroutines for performing common tasks. CASE/A version 5.0 software runs under the VAX VMS(Trademark) environment. It utilizes the Tektronics 4014(Trademark) graphics display system and the VTIOO(Trademark) text manipulation/display system.

Thermal monitoring, measurement, and control system for a Volatile Condensable Materials (VCM) test apparatus

Ives, R. E.

1982-01-01

A thermal monitoring and control concept is described for a volatile condensable materials (VCM) test apparatus where electric resistance heaters are employed. The technique is computer based, but requires only proportioning ON/OFF relay control signals supplied through a programmable scanner and simple quadrac power controllers. System uniqueness is derived from automatic temperature measurements and the averaging of these measurements in discrete overlapping temperature zones. Overall control tolerance proves to be better than + or - 0.5 C from room ambient temperature to 150 C. Using precisely calibrated thermocouples, the method provides excellent temperature control of a small copper VCM heating plate at 125 + or - 0.2 C over a 24 hr test period. For purposes of unattended operation, the programmable computer/controller provides a continual data printout of system operation. Real time operator command is also provided for, as is automatic shutdown of the system and operator alarm in the event of malfunction.

In this paper we discuss the development of a MEMS-based solid state atom source that can provide controllable atom deposition ranging over eight orders of magnitude, from ten atoms per square micron up to hundreds of atomic layers, on a target ∼1 mm away. Using a micron-scale silicon plate as a thermal evaporation source we demonstrate the deposition of indium, silver, gold, copper, iron, aluminum, lead and tin. Because of their small sizes and rapid thermal response times, pulse width modulation techniques are a powerful way to control the atomic flux. Pulsing the source with precise voltages and timing provides control in terms of when and how many atoms get deposited. By arranging many of these devices into an array, one has a multi-material, programmable solid state evaporation source. These micro atom sources are a complementary technology that can enhance the capability of a variety of nano-fabrication techniques.

"TNOs are Cool": A survey of the trans-Neptunian region. XII. Thermal light curves of Haumea, 2003 VS2 and 2003 AZ84 with Herschel/PACS

Context. Time series observations of the dwarf planet Haumea and the Plutinos 2003 VS2 and 2003 AZ84 with Herschel/PACS are presented in this work. Thermal emission of these trans-Neptunian objects (TNOs) were acquired as part of the "TNOs are Cool" Herschel Space Observatory key programme. Aims: We search for the thermal light curves at 100 and 160 μm of Haumea and 2003 AZ84, and at 70 and 160 μm for 2003 VS2 by means of photometric analysis of the PACS data. The goal of this work is to use these thermal light curves to obtain physical and thermophysical properties of these icy Solar System bodies. Methods: When a thermal light curve is detected, it is possible to derive or constrain the object thermal inertia, phase integral and/or surface roughness with thermophysical modeling. Results: Haumea's thermal light curve is clearly detected at 100 and 160 μm. The effect of the reported dark spot is apparent at 100 μm. Different thermophysical models were applied to these light curves, varying the thermophysical properties of the surface within and outside the spot. Although no model gives a perfect fit to the thermal observations, results imply an extremely low thermal inertia (<0.5 J m-2 s-1/2 K-1, hereafter MKS) and a high phase integral (>0.73) for Haumea's surface. We note that the dark spot region appears to be only weakly different from the rest of the object, with modest changes in thermal inertia and/or phase integral. The thermal light curve of 2003 VS2 is not firmly detected at 70 μm and at 160 μm but a thermal inertia of (2 ± 0.5) MKS can be derived from these data. The thermal light curve of 2003 AZ84 is not firmly detected at 100 μm. We apply a thermophysical model to the mean thermal fluxes and to all the Herschel/PACS and Spitzer/MIPS thermal data of 2003 AZ84, obtaining a close to pole-on orientation as the most likely for this TNO. Conclusions: For the three TNOs, the thermal inertias derived from light curve analyses or from the thermophysical analysis of the mean thermal fluxes confirm the generally small or very small surface thermal inertias of the TNO population, which is consistent with a statistical mean value Γmean = 2.5 ± 0.5 MKS. Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA. PACS: The Photodetector Array Camera and Spectrometer is one of Herschel's instruments.

Soil organic matter composition from correlated thermal analysis and nuclear magnetic resonance data in Australian national inventory of agricultural soils

Moore, T. S.; Sanderman, J.; Baldock, J.; Plante, A. F.

2016-12-01

National-scale inventories typically include soil organic carbon (SOC) content, but not chemical composition or biogeochemical stability. Australia's Soil Carbon Research Programme (SCaRP) represents a national inventory of SOC content and composition in agricultural systems. The program used physical fractionation followed by 13C nuclear magnetic resonance (NMR) spectroscopy. While these techniques are highly effective, they are typically too expensive and time consuming for use in large-scale SOC monitoring. We seek to understand if analytical thermal analysis is a viable alternative. Coupled differential scanning calorimetry (DSC) and evolved gas analysis (CO2- and H2O-EGA) yields valuable data on SOC composition and stability via ramped combustion. The technique requires little training to use, and does not require fractionation or other sample pre-treatment. We analyzed 300 agricultural samples collected by SCaRP, divided into four fractions: whole soil, coarse particulates (POM), untreated mineral associated (HUM), and hydrofluoric acid (HF)-treated HUM. All samples were analyzed by DSC-EGA, but only the POM and HF-HUM fractions were analyzed by NMR. Multivariate statistical analyses were used to explore natural clustering in SOC composition and stability based on DSC-EGA data. A partial least-squares regression (PLSR) model was used to explore correlations among the NMR and DSC-EGA data. Correlations demonstrated regions of combustion attributable to specific functional groups, which may relate to SOC stability. We are increasingly challenged with developing an efficient technique to assess SOC composition and stability at large spatial and temporal scales. Correlations between NMR and DSC-EGA may demonstrate the viability of using thermal analysis in lieu of more demanding methods in future large-scale surveys, and may provide data that goes beyond chemical composition to better approach quantification of biogeochemical stability.

The thermal/vacuum facilities located at the Goddard Space Flight Center (GSFC) have supported both manned and unmanned space flight since the 1960s. Of the 11 facilities, currently 10 of the systems are scheduled for refurbishment and/or replacement as part of a 5-year implementation. Expected return on investment includes the reduction in test schedules, improvements in the safety of facility operations, reduction in the complexity of a test and the reduction in personnel support required for a test. Additionally, GSFC will become a global resource renowned for expertise in thermal engineering, mechanical engineering and for the automation of thermal/vacuum facilities and thermal/vacuum tests. Automation of the thermal/vacuum facilities includes the utilization of Programmable Logic Controllers (PLCs) and the use of Supervisory Control and Data Acquisition (SCADA) systems. These components allow the computer control and automation of mechanical components such as valves and pumps. In some cases, the chamber and chamber shroud require complete replacement while others require only mechanical component retrofit or replacement. The project of refurbishment and automation began in 1996 and has resulted in the computer control of one Facility (Facility #225) and the integration of electronically controlled devices and PLCs within several other facilities. Facility 225 has been successfully controlled by PLC and SCADA for over one year. Insignificant anomalies have occurred and were resolved with minimal impact to testing and operations. The amount of work remaining to be performed will occur over the next four to five years. Fiscal year 1998 includes the complete refurbishment of one facility, computer control of the thermal systems in two facilities, implementation of SCADA and PLC systems to support multiple facilities and the implementation of a Database server to allow efficient test management and data analysis.

Even powerful computational techniques like simulation endure limitations in their validity domain. Consequently using simulation models requires cautions to avoid making biased design decisions for new aeronautical products on the basis of inadequate simulation results. Thus the fidelity, accuracy and validity of simulation models shall be monitored in context all along the design phases to build confidence in achievement of the goals of modelling and simulation.In the CRESCENDO project, we adapt the Credibility Assessment Scale method from NASA standard for models and simulations from space programme to the aircraft design in order to assess the quality of simulations. The proposed eight quality assurance metrics aggregate information to indicate the levels of confidence in results. They are displayed in management dashboard and can secure design trade-off decisions at programme milestones.The application of this technique is illustrated in aircraft design context with specific thermal Finite Elements Analysis. This use case shows how to judge the fitness- for-purpose of simulation as Virtual testing means and then green-light the continuation of Simulation Lifecycle Management (SLM) process.

A single crystal of a low density form of guest-free p-tert-butylcalix[4]arene can take up and release small guest molecules by controlling the temperature and pressure without changing the structure. Using NMR spectroscopy with flowing hyperpolarized xenon, we have shown that at room temperature access of xenon to the pore system is difficult, whereas it is relatively easy at 100 degrees C. There are good prospects for simple van der Waals materials such as the title material to be used as programmable zeolite mimics.

Spin-state and thermophysical analysis of the near-Earth asteroid (8567) 1996 HW_1

The asteroid (8567) 1996 HW_1 is a near-Earth Amor-class asteroid. It has been a target of visual lightcurve observations during the two apparitions in 2005 [1,2] and 2008 [3]. The lightcurve datasets were complemented by the radar data obtained at Arecibo during the close approach in September 2008 [4]. The data was combined to constrain the shape and spin state of the asteroid. The sidereal spin rate was measured to be P = 8.76243 hours, and pole position expressed in ecliptic coordinates as λ=281°, β = -31°, with a complex rotation state not being ruled out. The shape of the asteroid resembles a contact binary with two components connected by a narrow neck. It was predicted that the asteroid's rotation rate is decreasing due to the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect. We aimed to verify the predicted YORP-induced period change [4]. The asteroid (8567) 1996 HW_1 has been selected as one of the targets of an ESO Large Programme led by Dr. S. Lowry. The programme includes photometric monitoring, infrared thermal observations, and visual near-infrared spectroscopy of selected near-Earth asteroids. Within the ESO LP, the asteroid has been observed on six runs between April 2010 and April 2013 with ESO's 3.6-m NTT telescope (Chile) to acquire optical lightcurves, and in September and December 2011 the infrared observations were performed with the VISIR instrument at the ESO's 8.2-m VLT telescope (Chile). The data set is completed by the visual lightcurve observations gathered from supporting programmes at JPL's Table Mountain Observatory (USA), Palomar 200-in telescope (USA), and the 2-m Liverpool Telescope (Spain). The visual lightcurves from our 2010-2013 observing campaign were combined with the previously published lightcurves from 2005-2009, doubling the time span of the observations for the purpose of the potential YORP detection. The shape model developed from radar and lightcurve data [4] has been used in the spin-state analysis. The current spin-state model reproduces the shape of all the lightcurves obtained over the eight years very well. We do not detect any signature of YORP in our data despite the long time base of our observations and the quality of the data obtained. The updated and improved spin-state model was used to determine the rotation phase of thermal fluxes obtained with VISIR very precisely. The thermal data was analysed using the Advanced Thermo-Physical Model (ATPM) [5,6]. The effective diameter is estimated to be 2.18 ± 0.05 km, which is consistent with the radar estimate of 2.02 ± 0.16 km. Thermal inertia is at the level of 170 ± 50 {Jm}^{-2}{K}^{-1}{s}^{-1/2} with roughness fraction above 75 %. The geometric albedo (using H = 15.27) can be constrained to P_ν = 0.29 ± 0.01. The ATPM modelling indicates a small YORP-induced acceleration at a rate of about 2.6 × 10^{-10} {rad} {d}^{-2} and an obliquity change of 0.9° per 10^5 years. The current value of obliquity, around 129.2°, is close to the critical value where the rotational component of YORP disappears. This result is in agreement with the results of our spin-state analysis. The detection of a period change at the predicted level may require a much longer observational time span. We note the difference in the sign between this prediction and the earlier estimates coming from the inclusion of large-scale self-heating in our analysis. For an object with a major concavity, it might occur that some parts of its surface will be irradiated by sunlight reflected off the other parts of the surface. This self-heating can significantly change the outcome of the YORP torque computation [7].

Taking on the Heat—a Narrative Account of How Infrared Cameras Invite Instant Inquiry

Integration of technology, social learning and scientific models offers pedagogical opportunities for science education. A particularly interesting area is thermal science, where students often struggle with abstract concepts, such as heat. In taking on this conceptual obstacle, we explore how hand-held infrared (IR) visualization technology can strengthen students' understanding of thermal phenomena. Grounded in the Swedish physics curriculum and part of a broader research programme on educational uses of IR cameras, we have developed laboratory exercises around a thermal storyline, in conjunction with the teaching of a heat-flow model. We report a narrative analysis of how a group of five fourth-graders, facilitated by a researcher, predicts, observes and explains (POE) how the temperatures change when they pour hot water into a ceramic coffee mug and a thin plastic cup. Four chronological episodes are described and analysed as group interaction unfolded. Results revealed that the students engaged cognitively and emotionally with the POE task and, in particular, held a sustained focus on making observations and offering explanations for the scenarios. A compelling finding was the group's spontaneous generation of multiple "what-ifs" in relation to thermal phenomena, such as blowing on the water surface, or submerging a pencil into the hot water. This was followed by immediate interrogation with the IR camera, a learning event we label instant inquiry. The students' expressions largely reflected adoption of the heat-flow model. In conclusion, IR cameras could serve as an access point for even very young students to develop complex thermal concepts.

The paper describes the testing of the NEUTON detection system into CROCUS, the zero-power reactor of the École Polytechnique Fédérale de Lausanne (EPFL). NEUTON is composed of a 4 mm × 4 mm sCVD diamond detector with a 6Li converter and the associated acquisition electronics. It is developed by CIVIDEC Instrumentation GmbH. The use of a diamond detector with converter in the mixed radiation field of a nuclear reactor is challenging because these detectors are sensitive to gamma-rays, fast neutrons and thermal neutrons through conversion in 6Li . In NEUTON, the rejection of gamma-rays is achieved in real time, via the analysis of the signal pulse shape from the detector. To do so, a few signal characteristics (amplitude, area and FWHM) are recorded in the integrated Field Programmable Gate Arrays (FPGA) of the system. This treatment does not induce any dead time. Measurements in CROCUS demonstrated for the first time the capability of a system like NEUTON to detect and separate fast neutrons, thermal neutrons, and gamma-rays. The system response was shown to be linear with respect to the reactor power (up to 35W) and its thermal sensitivity was found to be (3.5± 0.2)× 10^{-5} cps/nv.

Micro/nanophotonic structures that are capable of optical wave-front shaping are implemented in optical waveguides and passive optical devices to alter the phase of the light propagating through them. The beam division directions and beam power distribution depend on the design of the micro/nanostructures. The ultimate potential of advanced micro/nanophotonic structures is limited by their structurally rigid, functional singleness and not tunable against external impact. Here, we propose a thermally induced optical beam-power splitter concept based on a shape memory polystyrene film with programmable micropatterns. The smooth film exhibits excellent transparency with a transmittance of 95% in the visible spectrum and optical stability during a continuous heating process up to 90 °C. By patterning double sided shape memory polystyrene film into erasable and switchable micro-groove gratings, the transmission light switches from one designed light divided directions and beam-power distribution to another because of the optical diffraction effect of the shape changing micro gratings during the whole thermal activated recovery process. The experimental and theoretical results demonstrate a proof-of-principle of the beam-power splitter. Our results can be adapted to further extend the applications of micro/nanophotonic devices and implement new features in the nanophotonics.

All the recent DEMO design studies for helium cooled divertors utilize tungsten materials and alloys, mainly due to their high temperature strength, good thermal conductivity, low erosion, and comparably low activation under neutron irradiation. The long-term objective of the EFDA fusion materials programme is to develop structural as well as armor materials in combination with the necessary production and fabrication technologies for future divertor concepts. The programmatic roadmap is structured into four engineering research lines which comprise fabrication process development, structural material development, armor material optimization, and irradiation performance testing, which are complemented by a fundamental research programme on "Materials Science and Modeling". This paper presents the current research status of the EFDA experimental and testing investigations, and gives a detailed overview of the latest results on fabrication, joining, high heat flux testing, plasticity, modeling, and validation experiments.

The advanced along track scanning radiometer (aatsr) on esa's envisat satellite - an early assessment

NASA Astrophysics Data System (ADS)

Llewellyn-Jones, D.; Mutlow, C.; Smith, D.; Edwards, M.

The AATSR sensor is an imaging radiometer designed to measure top-of-the- atmosphere brightness temperature in seven thermal infrared, reflected infrared and visible wavelength channels. The main objective of the AATSR mission is to generate fields of global sea-surface temperature to the high levels of accuracy required for the monitoring and detection of climate change, and to support a broad range of associated research into the marine, terrestrial, cryospheric and atmospheric environments. An essential component of this objective is maintain continuity with the high-quality data-sets already collected form the two predecessor sensors, ATSR1 and 2 on ESA's ERS-1 and -2 satellites respectively. Following the successful launch of ENVISAT on March 1 2002, the AATSR sensor was activated and systematically brought up to full operating configuration in accordance with the agreed Switch-On and Data Acquisition Plan (SODAP). The early images form AATSR are of a quality that is consistent with its objective of effective data continuity. Since the instrument has been returning data, a programme of quality assessment has been taking place. This has included a systematic assessment of instrumental aspects such as signal-to-noise performance and image stability as well as the initial observations in the AATSR validation programme. In this programme, AATSR data-products are compared with correlative observations from other sources, which include, sea-borne radiometers, meteorological analysis fields and data from other satellites. This paper reports early results from some of the activities.

Background Programmes have had limited success in improving guideline adherence for chronic disease. Use of theory is recommended but is often absent in programmes conducted in ‘real-world’ rather than research settings. Materials and methods This mixed-methods study tested a retrospective theory-based approach to evaluate a ‘real-world’ programme in primary care to improve adherence to national guidelines for chronic obstructive pulmonary disease (COPD). Qualitative data, comprising analysis of documents generated throughout the programme (n>300), in-depth interviews with planners (clinicians, managers and improvement experts involved in devising, planning, and implementing the programme, n = 14) and providers (practice clinicians, n = 14) were used to construct programme theories, experiences of implementation and contextual factors influencing care. Quantitative analyses comprised controlled before-and-after analyses to test ‘early’ and evolved’ programme theories with comparators grounded in each theory. ‘Early’ theory predicted the programme would reduce emergency hospital admissions (EHA). It was tested using national analysis of standardized borough-level EHA rates between programme and comparator boroughs. ‘Evolved’ theory predicted practices with higher programme participation would increase guideline adherence and reduce EHA and costs. It was tested using a difference-in-differences analysis with linked primary and secondary care data to compare changes in diagnosis, management, EHA and costs, over time and by programme participation. Results Contrary to programme planners’ predictions in ‘early’ and ‘evolved’ programme theories, admissions did not change following the programme. However, consistent with ‘evolved’ theory, higher guideline adoption occurred in practices with greater programme participation. Conclusions Retrospectively constructing theories based on the ideas of programme planners can enable evaluators to address some limitations encountered when evaluating programmes without a theoretical base. Prospectively articulating theory aided by existing models and mid-range implementation theories may strengthen guideline adoption efforts by prompting planners to scrutinise implementation methods. Benefits of deriving programme theory, with or without the aid of mid-range implementation theories, however, may be limited when the evidence underpinning guidelines is flawed. PMID:28328942

This presentation suggests several Thermal Vacuum System (TVAC) control design approach methods for TVAC facilities. Over the past several years many aerospace companies have or are currently upgrading their TVAC testing facilities whether it be by upgrading old equipment or purchasing new. In doing so they are updating vacuum pumping and thermal capabilities of their chambers as well as their control systems. Although control systems are sometimes are considered second to the vacuum or thermal system upgrade process, they should not be taken lightly and must be planned and implemented with the equipment it is to control. Also, emphasis should be placed on how the operators will use the system as well as the requirements of "their" customers. Presented will be various successful methods of TVAC control systems from Programmable Logic Controller (PLC) based to personal computer (PC) based control.

The ultrasonic machining of silicon carbide / alumina composites

NASA Astrophysics Data System (ADS)

Nicholson, Garth Martyn John

Silicon carbide fibre reinforced alumina is a ceramic composite which was developed in conjunction with the Rolls-Royce Aerospace Group. The material is intended for use in the latest generation of jet engines, specifically for high temperature applications such as flame holders, combustor barrel segments and turbine blade tip seals. The material in question has properties which have been engineered by optimizing fibre volume fractions, weaves and fibre interface materials to meet the following main requirements : high thermal resistance, high thermal shock resistance and low density.Components intended for manufacture using this material will use the "direct metal oxidation" (DIMOX) method. This process involves manufacturing a near net shape component from the woven fibre matting, and infiltrating the matting with the alumina matrix material. Some of the components outlined require high tolerance features to be included in their design. The combustor barrel segments for example require slots to be formed within them for sealing purposes, the dimensions of these features preclude their formation using DIMOX, and therefore require a secondary process to be performed. Conventional machining techniques such as drilling, turning and milling cannot be used because of the brittle nature of the material. Electrodischarge machining (E.D.M.) cannot be used since the material is an insulator. Electrochemical machining (E.C.M.) cannot be used since the material is chemically inert. One machining method which could be used is ultrasonic machining (U.S.M.).The research programme investigated the feasibility of using ultrasonic machining as a manufacturing method for this new fibre reinforced composite. Two variations of ultrasonic machining were used : ultrasonic drilling and ultrasonic milling. Factors such as dimensional accuracy, surface roughness and delamination effects were examined. Previously performed ultrasonic machining experimental programmes were reviewed, as well as process models which have been developed. The process models were found to contain empirical constants which usually require specific material data for their calculation.Since a limited amount of the composite was available, and ultrasonic machining has many process variables, a Taguchi factorial experiment was conducted in order to ascertain the most relevant factors in machining. A full factorial experiment was then performed using the relevant factors. Techniques used in the research included both optical and scanning electron microscopy, surface roughness analysis, x-ray analysis and finite element stress analysis. A full set of machining data was obtained including relationships between the factors examined and both material removal rates, and surface roughness values. An attempt was made to explain these findings by examining established brittle fracture mechanisms. These established mechanisms did not seem to apply entirely to this material, an alternative method of material removal is therefore proposed. It is hoped that the data obtained from this research programme may contribute to the development of a more realistic mathematical model.

Ash from thermal power plants as secondary raw material.

2007-06-01

The basic characteristic of thermal power plants in the Republic of Serbia is that they use low-grade brown coal (lignite) as a fuel. Depending on the location of coal mines, lignite may have different properties such as heating value, moisture, and mineral content, resulting in different residue upon combustion. Because of several million tonnes of ash and slag generated every year, their granularmetric particle size distribution, and transport and disposal methods, these plants have a negative impact on the environment. According to the waste classification system in the Republic of Serbia, ash and slag from thermal power plants are classified as hazardous waste, but with an option of usability. The proposed revision of waste legislation in Serbia brings a number of simple and modern solutions. A procedure is introduced which allows for end-of-waste criteria to be set, clarifying the point where waste ceases to be waste, and thereby introducing regulatory relief for recycled products or materials that represent low risk for the environment. The new proposal refocuses waste legislation on the environmental impacts of the generation and management of waste, taking into account the life cycle of resources, and develops new waste prevention programmes. Stakeholders, as well as the general public, should have the opportunity to participate in the drawing up of the programmes, and should have access to them.

Here we study the influence of thermal fluctuations on the breakup of liquid ligaments at the nanoscale. We offer quantitative characterization of the effects of thermal fluctuations on the Plateau-Rayleigh mechanism that drives the breakup process of ligaments. Due to thermal fluctuations, the droplet sizes after break-up need to be analyzed in terms of their distribution over an ensemble made of repeated experiments. To this aim, we make use of numerical simulations based on the fluctuating lattice Boltzmann method (FLBM) for multicomponent mixtures. The method allows an accurate and efficient simulation of the fluctuating hydrodynamics equations of a binary mixture, where both stochastic viscous stresses and diffusion fluxes are introduced.

Programme evaluation tactics for child sponsorship programmes have historically concentrated on quantitative analysis of service units, amount of money invested, number of countries served, the number of projects, and number of children in each project. While these are valuable measures of programme variables, they do not assess the impact of programmes on the lives of the children sponsored. Outcome measures designed to assess programme impact add greatly to the information available to child welfare professionals. This study collected data about the impact of the programme on the lives of the children. The Child Welfare League's Child Well-Being Scales (CWBS) were used to assess programme impact. Twelve scales were chosen as directly related in type to the programmes administered by Children International, a traditional and well established child sponsorship organization located in Kansas City, Missouri. A thirteenth scale was suggested by field workers in India as particularly relevant to Third World populations. The scales were translated into languages appropriate to each population in the programme countries. Social workers in each country were trained to administer and score them. This analysis used the emerging data technology becoming available to programmes in Third World countries. The system enables administrators in the Third World to evaluate, enhance and summarize their programmes in a way understandable across borders. Epi Info (Dean et al., 1990) was customized to provide the framework for the analysis. The population for this study was selected by a 5% random sampling of children currently enrolled as sponsored children (180,000+ worldwide). These were compared with a waiting-list control group selected randomly from lists of children who have applied for sponsorship but have not yet been receiving services (n = 50 from each project).(ABSTRACT TRUNCATED AT 250 WORDS)

Objective To assess the cost-effectiveness of a multifaceted quality improvement programme focused on reducing central line-associated bloodstream infections in intensive care units. Design Cost-effectiveness analysis using a decision tree model to compare programme to non-programme intensive care units. Setting USA. Population Adult patients in the intensive care unit. Costs Economic costs of the programme and of central line-associated bloodstream infections were estimated from the perspective of the hospital and presented in 2013 US dollars. Main outcome measures Central line-associated bloodstream infections prevented, deaths averted due to central line-associated bloodstream infections prevented, and incremental cost-effectiveness ratios. Probabilistic sensitivity analysis was performed. Results Compared with current practice, the programme is strongly dominant and reduces bloodstream infections and deaths at no additional cost. The probabilistic sensitivity analysis showed that there was an almost 80% probability that the programme reduces bloodstream infections and the infections’ economic costs to hospitals. The opportunity cost of a bloodstream infection to a hospital was the most important model parameter in these analyses. Conclusions This multifaceted quality improvement programme, as it is currently implemented by hospitals on an increasingly large scale in the USA, likely reduces the economic costs of central line-associated bloodstream infections for US hospitals. Awareness among hospitals about the programme's benefits should enhance implementation. The programme's implementation has the potential to substantially reduce morbidity, mortality and economic costs associated with central line-associated bloodstream infections. PMID:25256190

Preterm birth is a rising health problem in Europe generally, and in Austria specifically. Decision makers require objective information on the effects and costs of measures to prevent preterm birth. We undertook a budget impact analysis from a public payer perspective and for a 1-year and 5-year time horizon for five prevention approaches to reduce preterm birth. These were cervix screening + progesterone application, progesterone injection, smoking cessation, fish oil supplementation and infection screening. We analysed affordability in terms of programme costs and potential cost savings. Programme costs range from below €50 000 (cervix screening in high-risk pregnancy) to €500 000 (universal infection screening). The lowest health effects have been shown for smoking cessation programmes (-10 preterm births per year), whereas infection screening demonstrated the largest effect (-230 preterm births per year). In the base-case analysis, all programmes are potentially cost saving (-€500 000 to -€13 million per year). In the sensitivity analyses, preterm birth costs, target group size and (partly) unit costs of programme components have an influence on potential cost savings. However, except for two programmes, the results are robust concerning an overall economic net benefit of the programmes analysed compared with no programme. The study is mainly limited by the quality of some cost data and choice of the reference scenario. When considering potential cost savings, the five prevention programmes analysed seem affordable, with cervix screening and infection screening likely being the most promising in Austria.

To describe and evaluate an innovative approach for developing leadership skills in a cohort of medical students through an extracurricular programme. The study was conducted at King Abdulaziz University, Jeddah, Saudi Arabia, from April to June of the academic year 2014-15, and comprised medical students from all batches. Mixed-method design was used to evaluate the leadership development programme. Pre- and post-tests were conducted to assess students' learning and their satisfaction was evaluated at the end of the programme. Focus groups were conducted to assess the programme's impact on participants' behaviour. Data analysis was done using SPSS 16. Of the 55 participants, 45(82%) responded to the evaluation survey. Of them, 29(65%) reported intended changes in their leadership practices immediately after the programme, with 8(28%) of them reporting more than one change. The mean students' satisfaction with the overall performance of the speakers and programme organisation was high at 4.12±0.91 and 4.54±0.89, respectively. Early experience of the leadership development programme produced positive results. An intense programme analysis is required to fully understand this significant organisational need.

The Mental Health Commission of Canada was formed as a national catalyst for improving the mental health system. One of its initiatives is Opening Minds (OM), whose mandate is to reduce mental health-related stigma. This article reports findings from a qualitative study on antistigma interventions for healthcare providers, which includes a process model articulating key stages and strategies for implementing successful antistigma programmes. The study employed a grounded theory methodology. Data collection involved in-depth interviews with programme stakeholders, direct observation of programmes, a review of programme documents, and qualitative feedback from programme participants. Analysis proceeded via the constant comparison method. A model was generated to visually present key findings. Twenty-three in-depth interviews were conducted representing 18 different programmes. Eight programmes were observed directly, 48 programme documents were reviewed, and data from 1812 programme participants were reviewed. The analysis led to a four-stage process model for implementing successful antistigma programmes targeting healthcare providers, informed by the basic social process 'targeting the roots of healthcare provider stigma'. The process model developed through this research may function as a tool to help guide the development and implementation of antistigma programmes in healthcare contexts. © 2016 John Wiley & Sons A/S.

A malaria eradication goal has been proposed, at the same time as a new global strategy and implementation framework. Countries are considering the strategies and tools that will enable progress towards malaria goals. The eliminating malaria case-study series reports were reviewed to identify successful programme management components using a cross-case study analytic approach. Nine out of ten case-study reports were included in the analysis (Bhutan, Cape Verde, Malaysia, Mauritius, Namibia, Philippines, Sri Lanka, Turkey, Turkmenistan). A conceptual framework for malaria elimination programme management was developed and data were extracted and synthesized. Findings were reviewed at a consultative workshop, which led to a revision of the framework and further data extraction and synthesis. Success factors of implementation, programme choices and changes, and enabling factors were distilled. Decentralized programmes enhanced engagement in malaria elimination by sub-national units and communities. Integration of the malaria programme into other health services was also common. Decentralization and integration were often challenging due to the skill and experience levels of newly tasked staff. Accountability for programme impact was not clarified for most programmes. Motivation of work force was a key factor in maintaining programme quality but there were few clear, detailed strategies provided. Different incentive schemes targeted various stakeholders. Training and supervision, although not well described, were prioritized by most programmes. Multi-sectoral collaboration helped some programmes share information, build strategies and interventions and achieve a higher quality of implementation. In most cases programme action was spurred by malaria outbreaks or a new elimination goal with strong leadership. Some programmes showed high capacity for flexibility through introduction of new strategies and tools. Several case-studies described methods for monitoring implementation quality and coverage; however analysis and feedback to those implementing malaria elimination in the periphery was not well described. Political commitment and sustained financing contributed to malaria programme success. Consistency of malaria programmes depends on political commitment, human and financial resources, and leadership. Operational capacity of the programme and the overall health system structure and strength are also important aspects. Malaria eradication will require adaptive, well-managed malaria programmes that are able to tailor implementation of evidence-based strategies, founded upon strong sub-national surveillance and response, with adequate funding and human resources.

Shoot development in grapevine (Vitis vinifera) is affected by the modular branching pattern of the stem and intra- and inter-shoot trophic competition.

2004-03-01

Shoot architecture variability in grapevine (Vitis vinifera) was analysed using a generic modelling approach based on thermal time developed for annual herbaceous species. The analysis of shoot architecture was based on various levels of shoot organization, including pre-existing and newly formed parts of the stem, and on the modular structure of the stem, which consists of a repeated succession of three phytomers (P0-P1-P2). Four experiments were carried out using the cultivar 'Grenache N': two on potted vines (one of which was carried out in a glasshouse) and two on mature vines in a vineyard. These experiments resulted in a broad diversity of environmental conditions, but none of the plants experienced soil water deficit. Development of the main axis was highly dependent on air temperature, being linearly related to thermal time for all stages of leaf development from budbreak to veraison. The stable progression of developmental stages along the main stem resulted in a thermal-time based programme of leaf development. Leaf expansion rate varied with trophic competition (shoot and cluster loads) and environmental conditions (solar radiation, VPD), accounting for differences in final leaf area. Branching pattern was highly variable. Classification of the branches according to ternary modular structure increased the accuracy of the quantitative analysis of branch development. The rate and duration of leaf production were higher for branches derived from P0 phytomers than for branches derived from P1 or P2 phytomers. Rates of leaf production, expressed as a -function of thermal time, were not stable and depended on trophic competition and environmental conditions such as solar radiation or VPD. The application to grapevine of a generic model developed in annual plants made it possible to identify constants in main stem development and to determine the hierarchical structure of branches with respect to the modular structure of the stem in response to intra- and inter-shoot trophic competition.

The choice of programmable or nonprogrammable shunts for the management of hydrocephalus after aneurysmal subarachnoid hemorrhage (SAH) remains undefined. Variable intracranial pressures make optimal management difficult. Programmable shunts have been shown to reduce problems with drainage, but at 3 times the cost of nonprogrammable shunts. All patients who underwent insertion of a ventriculoperitoneal shunt for hydrocephalus after aneurysmal SAH between 2006 and 2012 were included. Patients were divided into those in whom nonprogrammable shunts and those in whom programmable shunts were inserted. The rates of shunt revisions, the reasons for adjustments of shunt settings in patients with programmable devices, and the effectiveness of the adjustments were analyzed. A cost-benefit analysis was also conducted to determine if the overall cost for programmable shunts was more than for nonprogrammable shunts. Ninety-four patients underwent insertion of shunts for hydrocephalus secondary to SAH. In 37 of these patients, nonprogrammable shunts were inserted, whereas in 57 programmable shunts were inserted. Four (7%) of 57 patients with programmable devices underwent shunt revision, whereas 8 (21.6%) of 37 patients with nonprogrammable shunts underwent shunt revision (p = 0.0413), and 4 of these patients had programmable shunts inserted during shunt revision. In 33 of 57 patients with programmable shunts, adjustments were made. The adjustments were for a trial of functional improvement (n = 21), overdrainage (n = 5), underdrainage (n = 6), or overly sunken skull defect (n = 1). Of these 33 patients, 24 showed neurological improvements (p = 0.012). Cost-benefit analysis showed $646.60 savings (US dollars) per patient if programmable shunts were used, because the cost of shunt revision is a lot higher than the cost of the shunt. The rate of shunt revision is lower in patients with programmable devices, and these are therefore more cost-effective. In addition, the shunt adjustments made for patients with programmable devices also resulted in better neurological outcomes.

Nurse manager succession planning: A cost-benefit analysis.

This commentary presents a cost-benefit analysis to advocate for the use of succession planning to mitigate the problems ensuing from nurse manager turnover. An estimated 75% of nurse managers will leave the workforce by 2020. Many benefits are associated with proactively identifying and developing internal candidates. Fewer than 7% of health care organisations have implemented formal leadership succession planning programmes. A cost-benefit analysis of a formal succession-planning programme from one hospital illustrates the benefits of the programme in their organisation and can be replicated easily. Assumptions of nursing manager succession planning cost-benefit analysis are identified and discussed. The succession planning exemplar demonstrates the integration of cost-benefit analysis principles. Comparing the costs of a formal nurse manager succession planning strategy with the status quo results in a positive cost-benefit ratio. The implementation of a formal nurse manager succession planning programme effectively reduces replacement costs and time to transition into the new role. This programme provides an internal pipeline of future leaders who will be more successful than external candidates. Using an actual cost-benefit analysis equips nurse managers with valuable evidence depicting succession planning as a viable business strategy. © 2017 John Wiley & Sons Ltd.

Satellite data show a steady increase, in the last decades, of the surface temperature (upper few millimetres of the water surface) of the Mediterranean Sea. Reports of mass mortalities of benthic marine invertebrates increased in the same period. Some local studies interpreted the two phenomena in a cause-effect fashion. However, a basin-wide picture of temperature changes combined with a systematic assessment on invertebrate mass mortalities was still lacking. Both the thermal structure of the water column in the Mediterranean Sea over the period 1945-2011 and all documented invertebrate mass mortality events in the basin are analysed to ascertain if: 1- documented mass mortalities occurred under conditions of positive temperature trends at basin scale, and 2- atypical thermal conditions were registered at the smaller spatial and temporal scale of mass mortality events. The thermal structure of the shallow water column over the last 67 years was reconstructed using data from three public sources: MEDAR-MEDATLAS, World Ocean Database, MFS-VOS programme. A review of the mass mortality events of benthic invertebrates at Mediterranean scale was also carried out. The analysis of in situ temperature profiles shows that the Mediterranean Sea changed in a non-homogeneous fashion. The frequency of mass mortalities is increasing. The areas subjected to these events correspond to positive thermal anomalies. Statistically significant temperature trends in the upper layers of the Mediterranean Sea show an increase of up to 0.07°C/yr for a large fraction of the basin. Mass mortalities are consistent with both the temperature increase at basin scale and the thermal changes at local scale, up to 5.2°C. Our research supports the existence of a causal link between positive thermal anomalies and observed invertebrate mass mortalities in the Mediterranean Sea, invoking focused mitigation initiatives in sensitive areas.

PID-controller with predictor and auto-tuning algorithm: study of efficiency for thermal plants

NASA Astrophysics Data System (ADS)

Kuzishchin, V. F.; Merzlikina, E. I.; Hoang, Van Va

2017-09-01

The problem of efficiency estimation of an automatic control system (ACS) with a Smith predictor and PID-algorithm for thermal plants is considered. In order to use the predictor, it is proposed to include an auto-tuning module (ATC) into the controller; the module calculates parameters for a second-order plant module with a time delay. The study was conducted using programmable logical controllers (PLC), one of which performed control, ATC, and predictor functions. A simulation model was used as a control plant, and there were two variants of the model: one of them was built on the basis of a separate PLC, and the other was a physical model of a thermal plant in the form of an electrical heater. Analysis of the efficiency of the ACS with the predictor was carried out for several variants of the second order plant model with time delay, and the analysis was performed on the basis of the comparison of transient processes in the system when the set point was changed and when a disturbance influenced the control plant. The recommendations are given on correction of the PID-algorithm parameters when the predictor is used by means of using the correcting coefficient k for the PID parameters. It is shown that, when the set point is changed, the use of the predictor is effective taking into account the parameters correction with k = 2. When the disturbances influence the plant, the use of the predictor is doubtful, because the transient process is too long. The reason for this is that, in the neighborhood of the zero frequency, the amplitude-frequency characteristic (AFC) of the system with the predictor has an ascent in comparison with the AFC of the system without the predictor.

Risk management and lessons learned solutions for satellite product assurance

NASA Astrophysics Data System (ADS)

Larrère, Jean-Luc

2004-08-01

The historic trend of the space industry towards lower cost programmes and more generally a better economic efficiency raises a difficult question to the quality assurance community: how to achieve the same—or better—mission success rate while drastically reducing the cost of programmes, hence the cost and level of quality assurance activities. EADS Astrium Earth Observation and Science (France) Business Unit have experimented Risk Management and Lessons Learned on their satellite programmes to achieve this goal. Risk analysis and management are deployed from the programme proposal phase through the development and operations phases. Results of the analysis and the corresponding risk mitigation actions are used to tailor the product assurance programme and activities. Lessons learned have been deployed as a systematic process to collect positive and negative experience from past and on-going programmes and feed them into new programmes. Monitoring and justification of their implementation in programmes is done under supervision from the BU quality assurance function. Control of the system is ensured by the company internal review system. Deployment of these methods has shown that the quality assurance function becomes more integrated in the programme team and development process and that its tasks gain focus and efficiency while minimising the risks associated with new space programmes.

The publication of Best research for best health in 2006 and the "ring-fencing" of health research funding in England marked the start of a period of change for health research governance and the structure of research funding in England. One response to bridging the 'second translational gap' between research knowledge and clinical practice was the establishment of nine Collaborations for Leadership in Applied Health Research and Care (CLAHRCs). The goal of this paper is to assess how national-level understanding of the aims and objectives of the CLAHRCs translated into local implementation and practice in North West London. This study uses a variation of Goffman's frame analysis to trace the development of the initial national CLAHRC policy to its implementation at three levels. Data collection and analysis were qualitative through interviews, document analysis and embedded research. Analysis at the macro (national policy), meso (national programme) and micro (North West London) levels shows a significant common understanding of the aims and objectives of the policy and programme. Local level implementation in North West London was also consistent with these. The macro-meso-micro frame analysis is a useful way of studying the transition of a policy from high-level idea to programme in action. It could be used to identify differences at a local (micro) level in the implementation of multi-site programmes that would help understand differences in programme effectiveness.

Relevance of the EU Structural Funds’ Allocation to the Needs of Combating Air Pollution in Poland. Analysis of the Operational Programmes of Regions Threatened With Critical Air Pollution from Distributed Energy Sources

Recent years, the European Environmental Agency, has been reporting air quality parameters in Poland, as the poorest among all the EU countries. Despite of adoption of the EU legislation on energy efficiency and energy performance of buildings, existing legal solutions occur insufficient in reducing air pollution in Polish regions. Lack of an effective schemes supporting complex thermal renovation of buildings, exchange of inefficient boilers, developing district heating based on clean and renewable fuels results in severe health problems and 40 000 of premature deaths related to air pollution. Availability of the EU structural funds may become a tremendous opportunity, especially for the residential sector, to conduct a massive scale modernization. Nevertheless, lack of a coordinated action involving all levels of governance may put the opportunity at risk. The article aims to answer the question on the readiness of the regional governments to effectively implement energy efficiency measures mitigating the problem of air pollution. Second objective is to analyse whether the Regional Operational Programmes allocating the ERDF funds to support specific development needs of the regions, have been constructed in a way that properly addresses the problems related to energy performance of residential buildings.

Images, femininity and cancer: an analysis of an international patient education programme.

Phillips, Catherine

2009-01-01

This article is an analysis of a cancer patient education programme run by cosmetic companies. I focus on an analysis of imagery, arguing that there are particular discursive elements that the cosmetic companies use in order to make productive the relationship between femininity and cancer. I contextualize this education programme by presenting the controversies regarding cosmetics as they relate to the growth of breast tumours. In doing so, I conclude that conversations and questions about a link between chemicals and cancer are subverted by both ;horror' narratives of cancer and the provocative use of standards of beauty. Such discursive dominance in patient education programmes makes it difficult to engage in a more public understanding of cancer growth as affected by cosmetic chemicals.

The mission of the Multispectral Thermal Imager (MTI) satellite is to demonstrate the efficacy of highly accurate multispectral imaging for passive characterization of urban and industrial areas, as well as sites of environmental interest. The satellite makes top-of-atmosphere radiance measurements that are subsequently processed into estimates of surface properties such as vegetation health, temperatures, material composition and others. The MTI satellite also provides simultaneous data for atmospheric characterization at high spatial resolution. To utilize these data the MTI science program has several coordinated components, including modeling, comprehensive ground-truth measurements, image acquisition planning, data processing and data interpretation and analysis. Algorithms have been developed to retrieve a multitude of physical quantities and these algorithms are integrated in a processing pipeline architecture that emphasizes automation, flexibility and programmability. In addition, the MTI science team has produced detailed site, system and atmospheric models to aid in system design and data analysis. This paper provides an overview of the MTI research objectives, data products and ground data processing.

Stepien, M.; Grzesik, B.

2014-05-01

The paper concerns the analysis of transient state (quench transition) in HTS tapes loaded with the current having DC component together with a ripple component. Two shapes of the ripple were taken into account: sinusoidal and triangular. Very often HTS tape connected to a power electronic current supply (i.e. superconducting coil for SMES) that delivers DC current with ripples and it needs to be examined under such conditions. Additionally, measurements of electrical (and thermal) parameters under such ripple excitation is useful to tape characterization in broad range of load currents. The results presented in the paper were obtained using test bench which contains programmable DC supply and National Instruments data acquisition system. Voltage drops and load currents were measured vs. time. Analysis of measured parameters as a function of the current was used to tape description with quench dynamics taken into account. Results of measurements were also used to comparison with the results of numerical modelling based on FEM. Presented provisional results show possibility to use results of measurements in transient state to prepare inverse models of superconductors and their detailed numerical modelling.

Unlike monometallic materials, bimetallic plasmonic materials offer extensive benefits such as broadband tuning capability or high environmental stability. Here we report a broad range tuning of plasmon resonance of alloyed nanoislands by using solid-state dewetting of gold and silver bilayer thin films. Thermal dewetting after successive thermal evaporation of thin metal double-layer films readily forms AuAg-alloyed nanoislands with a precise composition ratio. The complete miscibility of alloyed nanoislands results in programmable tuning of plasmon resonance wavelength in a broadband visible range. Such extraordinary tuning capability opens up a new direction for plasmonic enhancement in biophotonic applications such as surface-enhanced Raman scattering or plasmon-enhanced fluorescence.

Aldrich, B. R.; Whitt, W. D. (Inventor)

1979-01-01

A multipurpose furnace for space vehicles used for material processing experiments in an outer space environment is described. The furnace contains three separate cavities designed to process samples of the widest possible range of materials and thermal requirements. Each cavity contains three heating elements capable of independent function under the direction of an automatic and programmable control system. A heat removable mechanism is also provided for each cavity which operates in conjunction with the control system for establishing an isothermally heated cavity or a wide range of thermal gradients and cool down rates. A monitoring system compatible with the rocket telemetry provides furnace performance and sample growth rate data throughout the processing cycle.

1997-01-01

The paper deals with the refurbishing and upgrade of the thermal system for the existing thermal vacuum test facility, the Space Environment Simulator, at NASA's Goddard Space Flight Center. The chamber is the largest such facility at the center. This upgrade is the third phase of the long range upgrade of the chamber that has been underway for last few years. The first phase dealt with its vacuum system, the second phase involved the GHe subsystem. The paper describes the considerations of design philosophy options for the thermal system; approaches taken and methodology applied, in the evaluation of the remaining "life" in the chamber shrouds and related equipment by conducting special tests and studies; feasibility and extent of automation, using computer interfaces and Programmable Logic Controllers in the control system and finally, matching the old components to the new ones into an integrated, highly reliable and cost effective thermal system for the facility. This is a multi-year project just started and the paper deals mainly with the plans and approaches to implement the project successfully within schedule and costs.

The thermal vacuum facilities located at the Goddard Space Flight Center (GSFC) have supported both manned and unmanned space flight since the 1960s. Of the eleven facilities, currently ten of the systems are scheduled for refurbishment or replacement as part of a five-year implementation. Expected return on investment includes the reduction in test schedules, improvements in safety of facility operations, and reduction in the personnel support required for a test. Additionally, GSFC will become a global resource renowned for expertise in thermal engineering, mechanical engineering, and for the automation of thermal vacuum facilities and tests. Automation of the thermal vacuum facilities includes the utilization of Programmable Logic Controllers (PLCs), the use of Supervisory Control and Data Acquisition (SCADA) systems, and the development of a centralized Test Data Management System. These components allow the computer control and automation of mechanical components such as valves and pumps. The project of refurbishment and automation began in 1996 and has resulted in complete computer control of one facility (Facility 281), and the integration of electronically controlled devices and PLCs in multiple others.

2011-01-01

The final target of this study is to achieve a better understanding of the behavior of thermally sprayed abradable seals such as AlSi/polyester composites. These coatings are used as seals between the static and the rotating parts in aero-engines. The machinability of the composite coatings during the friction of the blades depends on their mechanical and thermal effective properties. In order to predict these properties from micrographs, numerical studies were performed with different software packages such as OOF developed by NIST and TS2C developed at the UTBM. In 2008, differences were reported concerning predictions of effective thermal conductivities obtained with the two codes. In this article, a particular attention was paid to the mathematical formulation of the problem. In particular, results obtained with a finite difference method using a cell-centered approach or a nodal formulation allow explaining the discrepancies previously noticed. A comparison of the predictions of the computed effective thermal conductivities is thus proposed. This study is part of the NEWAC project, funded by the European Commission within the 6th RTD Framework programm (FP6).

We have synthesized a new thermally and dimensionally stable polyimide, poly(4,4'-amino(4-hydroxyphenyl)diphenylene hexafluoroisopropylidenediphthalimide) (6F-HTPA PI). 6F-HTPA PI is soluble in organic solvents and is thus easily processed with conventional solution coating techniques to produce good quality nanoscale thin films. Devices fabricated with nanoscale thin PI films with thicknesses less than 77 nm exhibit excellent unipolar write-once-read-many-times (WORM) memory behavior with a high ON/OFF current ratio of up to 10(6), a long retention time and low power consumption, less than +/-3.0 V. Furthermore, these WORM characteristics were found to persist even at high temperatures up to 150 degrees C. The WORM memory behavior was found to be governed by trap-limited space-charge limited conduction and local filament formation. The conduction processes are dominated by hole injection. Thus the hydroxytriphenylamine moieties of the PI polymer might play a key role as hole trapping sites in the observed WORM memory behavior. The properties of 6F-HTPA PI make it a promising material for high-density and very stable programmable permanent data storage devices with low power consumption.

1994-01-01

Spacecraft thermal control is accomplished for many components through use of multilayer insulation systems, electrical heaters, and radiator systems. The heaters are commanded to maintain component temperatures within design specifications. The programmable heater control circuit (PHCC) was designed to obtain an effective and efficient means of spacecraft thermal control. The hybrid circuit provides use of control instrumentation as temperature data, available to the spacecraft central data system, reprogramming capability of the local microprocessor during the spacecraft's mission, and the elimination of significant spacecraft wiring. The hybrid integrated circuit has a temperature sensing and conditioning circuit, a microprocessor, and a heater power and control circuit. The device is miniature and housed in a volume which allows physical integration with the component to be controlled. Applications might include alternate battery-powered logic-circuit configurations. A prototype unit with appropriate physical and functional interfaces was procured for testing. The physical functionality and the feasibility of fabrication of the hybrid integrated circuit were successfully verified. The remaining work to develop a flight-qualified device includes fabrication and testing of a Mil-certified part. An option for completing the PHCC flight qualification testing is to enter into a joint venture with industry.

Background Truck drivers have unique health needs, and by virtue of their continuous travel, experience difficulty in accessing healthcare. Currently, planning for effective care is hindered by lack of knowledge about their health needs and about the impact of on-going programmes on this population’s health outcomes. We reviewed healthcare programmes implemented for sub-Saharan African truck drivers, assessed the evaluation methods, and examined impact on health outcomes. Methods We searched scientific and institutional databases, and online search engines to include all publications describing a healthcare programme in sub-Saharan Africa where the main clients were truck drivers. We consulted experts and organisations working with mobile populations to identify unpublished reports. Forest plots of impact and outcome indicators with unadjusted risk ratios and 95% confidence intervals were created to map the impact of these programmes. We performed a subgroup analysis by type of indicator using a random-effects model to assess between-study heterogeneity. We conducted a sensitivity analysis to examine both the summary effect estimate chosen (risk difference vs. risk ratio) and model to summarise results (fixed vs. random effects). Results Thirty-seven publications describing 22 healthcare programmes across 30 countries were included from 5,599 unique records. All programmes had an HIV-prevention focus with only three expanding their services to cover conditions other primary healthcare services. Twelve programmes were evaluated and most evaluations assessed changes in input, output, and outcome indicators. Absence of comparison groups, preventing attribution of the effect observed to the programme and lack of biologically confirmed outcomes were the main limitations. Four programmes estimated a quantitative change in HIV prevalence or reported STI incidence, with mixed results, and one provided anecdotal evidence of changes in AIDS-related mortality and social norms. Most programmes showed positive changes in risk behaviours, knowledge, and attitudes. Our conclusions were robust in sensitivity analyses. Conclusion Diverse healthcare programmes tailored to the needs of truck drivers implemented in 30 sub-Saharan African countries have shown potential benefits. However, information gaps about availability of services and their effects impede further planning and implementation of effective healthcare programmes for truck drivers. PMID:27333301

What Counts is not Falling … but Landing: Strategic Analysis: An Adapted Model for Implementation Evaluation.

PubMed

Brousselle, Astrid

2004-04-01

Implementation evaluations, also called process evaluations, involve studying the development of programmes, and identifying and understanding their strengths and weaknesses. Undertaking an implementation evaluation offers insights into evaluation objectives, but does not help the researcher develop a research strategy. During the implementation analysis of the UNAIDS drug access initiative in Chile, the strategic analysis model developed by Crozier and Friedberg was used. However, a major incompatibility was noted between the procedure put forward by Crozier and Friedberg and the specific characteristics of the programme being evaluated. In this article, an adapted strategic analysis model for programme evaluation is proposed.

The objective of the present study is to develop and pilot a communication and influencing skills training programme that meets ED health professionals' needs at an urban district hospital. Qualitative methods within a participatory action research framework were utilised. An interdisciplinary team guided the programme's design and development. A training needs analysis saw team meetings, interviews, focus groups and observations conducted across the ED. Thematic analysis of the data identified health professionals' communication and influencing challenges. The training needs analysis informed the training programme curriculum's development. The pilot programme involved an interdisciplinary group of seven health professionals across 5 × 2 h sessions over 3 months, followed by a post-training survey. Five themes of communication and influencing challenges were identified: participating in effective handovers, involving patients in bedside handovers, effectively communicating with interdepartmental colleagues, asking ED colleagues to do tasks and understanding ED colleagues' roles, expectations and assumptions. Based on these challenges, the formulated RESPECT model (which stands for Relationships, Expectations, Styles, Partnerships, Enquiry, Coaching and Teamwork) informed the training curriculum. The peer coaching model used in the training programme was highly regarded by participants. Communication and Influencing for ED Professionals™ (Babel Fish Group Pty Ltd, Melbourne, Victoria, Australia) addresses a gap for communication programmes developed in the ED for the ED. Future research will evaluate the programme's impact in this ED. © 2016 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Studying policy implementation using a macro, meso and micro frame analysis: the case of the Collaboration for Leadership in Applied Health Research & Care (CLAHRC) programme nationally and in North West London

PubMed Central

2012-01-01

Background The publication of Best research for best health in 2006 and the “ring-fencing” of health research funding in England marked the start of a period of change for health research governance and the structure of research funding in England. One response to bridging the ‘second translational gap’ between research knowledge and clinical practice was the establishment of nine Collaborations for Leadership in Applied Health Research and Care (CLAHRCs). The goal of this paper is to assess how national-level understanding of the aims and objectives of the CLAHRCs translated into local implementation and practice in North West London. Methods This study uses a variation of Goffman’s frame analysis to trace the development of the initial national CLAHRC policy to its implementation at three levels. Data collection and analysis were qualitative through interviews, document analysis and embedded research. Results Analysis at the macro (national policy), meso (national programme) and micro (North West London) levels shows a significant common understanding of the aims and objectives of the policy and programme. Local level implementation in North West London was also consistent with these. Conclusions The macro-meso-micro frame analysis is a useful way of studying the transition of a policy from high-level idea to programme in action. It could be used to identify differences at a local (micro) level in the implementation of multi-site programmes that would help understand differences in programme effectiveness. PMID:23067208

Background While HIV has had a major impact on health care in southern Africa, there are few data on its impact on acute malnutrition in children in the community. We report an analysis of outcomes in a large programme of community management of acute malnutrition in the south of Lusaka. Programme Activities and Analysis Over 3 years, 68,707 assessments for undernutrition were conducted house-to-house, and children with severe acute malnutrition (SAM) or moderate acute malnutrition (MAM) were enrolled into either Outpatient Therapeutic Programme (OTP) or Supplementary Feeding Programme (SFP) respectively. Case records were analysed using tabulation and unconditional logistic regression. Findings 1,859 children (889 boys, 970 girls; median age 16 months) with MAM (n = 664) or SAM (n = 1,195) were identified. Of 1,796 children whose parents consented to testing, 185 (10.3%) were HIV positive. Altogether 1,163 (62.6%) were discharged as recovered from acute malnutrition. Case fatality while in the programme was 4.2% in children with SAM and 0.5% in those with MAM (RR of SAM 10.9; 95%CI 3.4,34.8; P<0.0001), and higher in children with HIV infection (RR 5.2, 95%CI 2.9, 9.0; P<0.0001). In multivariate analysis, HIV (OR 5.2; 95%CI 2.6, 10.1; P<0.0001), MUAC <11.5cm (OR 4.1; 95%CI 2.2, 7.4; P<0.0001) and the first year of the programme (OR 1.9; 95%CI 1.0, 3.4; P = 0.04) all increased mortality. Children with HIV infection who were able to initiate antiretroviral therapy had lower mortality (RR 0.23; 95%CI 0.10, 0.57; P = 0.0008). Interpretation Our programme suggests that a comprehensive community malnutrition programme, incorporating HIV care, can achieve low mortality even in a population heavily affected by HIV.

Industrial robots are widely used in the field of thermal spray nowadays. Due to their characteristics of high-accuracy and programmable flexibility, spraying on complex geometrical workpieces can be realized in the equipped spray room. However, in some cases, the robots cannot guarantee the process parameters defined by the robot movement, such as the scanning trajectory, spray angle, relative speed between the torch and the substrate, etc., which have distinct influences on heat and mass transfer during the generation of any thermally sprayed coatings. In this study, an investigation on the robot kinematics was proposed to find the rules of motion in a common case. The results showed that the motion behavior of each axis of robot permits to identify the motion problems in the trajectory. This approach allows to optimize the robot trajectory generation in a limited working envelop. It also minimizes the influence of robot performance to achieve a more constant relative scanning speed which is represented as a key parameter in thermal spraying.

Contribution of space platforms to a ground and airborne remote-sensing programme over active Italian volcanoes

Cassinis, R.; Lechi, G. M.; Tonelli, A. M.

1974-01-01

ERTS-1 imagery of the volcanic areas of southern Italy was used primarily for the evaluation of space platform capabilties in the domains of regional geology, soil and rock-type classification and, more generally, to study the environment of active volcanoes. The test sites were selected and equipped primarily to monitor thermal emission, but ground truth data was also collected in other domains (reflectance of rocks, soils and vegetation). The test areas were overflown with a two channel thermal scanner, while a thermo camera was used on the ground to monitor the hot spots. The primary goal of this survey was to plot the changes in thermal emission with time in the framework of a research program for the surveillance of active volcanoes. However, another task was an evaluation of emissivity changes by comparing the outputs of the two thermal channels. These results were compared with the reflectance changes observed on multispectral ERTS-1 imagery.

Schönig, W

2002-01-01

Public and private expenditure in health recovery programmes for mothers and their children is stagnating. A focal point to turn around this trend is to convince the responsible statury bodies by proving both effectiveness and efficiency of these programmes. The paper suggests the application of the break-even analysis on a time-based principle. A primary calculation with the data of a major German evaluation shows significant savings if the success of the health recovery programmes holds for at least 1.19 years. Available data does not cover such a long period.

Evaluation of Bioinformatic Programmes for the Analysis of Variants within Splice Site Consensus Regions

Tang, Rongying; Prosser, Debra O.; Love, Donald R.

2016-01-01

The increasing diagnostic use of gene sequencing has led to an expanding dataset of novel variants that lie within consensus splice junctions. The challenge for diagnostic laboratories is the evaluation of these variants in order to determine if they affect splicing or are merely benign. A common evaluation strategy is to use in silico analysis, and it is here that a number of programmes are available online; however, currently, there are no consensus guidelines on the selection of programmes or protocols to interpret the prediction results. Using a collection of 222 pathogenic mutations and 50 benign polymorphisms, we evaluated the sensitivity and specificity of four in silico programmes in predicting the effect of each variant on splicing. The programmes comprised Human Splice Finder (HSF), Max Entropy Scan (MES), NNSplice, and ASSP. The MES and ASSP programmes gave the highest performance based on Receiver Operator Curve analysis, with an optimal cut-off of score reduction of 10%. The study also showed that the sensitivity of prediction is affected by the level of conservation of individual positions, with in silico predictions for variants at positions −4 and +7 within consensus splice sites being largely uninformative.

The fast increasing share of distributed generation from non-programmable renewable energy sources, such as the strong penetration of photovoltaic technology in the distribution networks, has generated several problems for the management and security of the whole power grid. In order to meet the challenge of a significant share of solar energy in the electricity mix, several actions aimed at increasing the grid flexibility and its hosting capacity, as well as at improving the generation programmability, need to be investigated. This paper focuses on the ongoing preliminary studies at the Ottana Solar Facility, a new experimental power plant located in Sardinia (Italy) currently under construction, which will offer the possibility to progress in the study of solar plants integration in the power grid. The facility integrates a concentrating solar power (CSP) plant, including a thermal energy storage system and an organic Rankine cycle (ORC) unit, with a concentrating photovoltaic (CPV) plant and an electrical energy storage system. The facility has the main goal to assess in real operating conditions the small scale concentrating solar power technology and to study the integration of the two technologies and the storage systems to produce programmable and controllable power profiles. A model for the CSP plant yield was developed to assess different operational strategies that significantly influence the plant yearly yield and its global economic effectiveness. In particular, precise assumptions for the ORC module start-up operation behavior, based on discussions with the manufacturers and technical datasheets, will be described. Finally, the results of the analysis of the: "solar driven", "weather forecasts" and "combined storage state of charge (SOC)/ weather forecasts" operational strategies will be presented.

Background Operation Installation (OI), a community-based smoke alarm installation programme in Dallas, Texas, targets houses in high-risk urban census tracts. Residents of houses that received OI installation (or programme houses) had 68% fewer medically treated house fire injuries (non-fatal and fatal) compared with residents of non-programme houses over an average of 5.2 years of follow-up during an effectiveness evaluation conducted from 2001 to 2011. Objective To estimate the cost–benefit of OI. Methods A mathematical model incorporated programme cost and effectiveness data as directly observed in OI. The estimated cost per smoke alarm installed was based on a retrospective analysis of OI expenditures from administrative records, 2006–2011. Injury incidence assumptions for a population that had the OI programme compared with the same population without the OI programme was based on the previous OI effectiveness study, 2001–2011. Unit costs for medical care and lost productivity associated with fire injuries were from a national public database. Results From a combined payers’ perspective limited to direct programme and medical costs, the estimated incremental cost per fire injury averted through the OI installation programme was $128,800 (2013 US$). When a conservative estimate of lost productivity among victims was included, the incremental cost per fire injury averted was negative, suggesting long-term cost savings from the programme. The OI programme from 2001 to 2011 resulted in an estimated net savings of $3.8 million, or a $3.21 return on investment for every dollar spent on the programme using a societal cost perspective. Conclusions Community smoke alarm installation programmes could be cost-beneficial in high-fire-risk neighbourhoods. PMID:28183740

The interdisciplinary postgraduate research and education programme - the Vienna Doctoral Programme on Water Resource Systems - was initiated in 2009. To date, 35 research students, three post-docs and ten faculty members have been engaged in the Programme, from ten research fields (aquatic microbiology, hydrology, hydro-climatology, hydro-geology, mathematical economics, photogrammetry, remote sensing, resource management, structural mechanics, and water quality). The Programme aims to develop research students with the capacity to work across the disciplines, to conduct cutting edge research and foster an international perspective. To do this, a variety of mechanisms are adopted that include research cluster groups, joint study sites, joint supervision, a basic study programme and a research semester abroad. The Programme offers a unique case study to explore if and how these mechanisms lead to research and education outcomes. Outcomes are grouped according to whether they are tangible (publications with co-authors from more than one research field, analysis of graduate profiles and career destinations) or non-tangible (interaction between researchers, networks and trust). A mixed methods approach that includes bibliometric analysis combined with interviews with students is applied. Bibliometric analysis shows that as the Programme has evolved the amount of multi-disciplinary work has increased (32% of the 203 full papers produced by the programme's researchers have authors from more than one research field). Network analysis to explore which research fields collaborate most frequently show that hydrology plays a significant role and has collaborated with seven of the ten research fields. Hydrology researchers seem to interact the most strongly with other research fields as they contribute understanding on water system processes. Network analysis to explore which individuals collaborate shows that much joint work takes place through the five research cluster groups (water resource management, land-surface processes, Hydrological Open Air Laboratory, water and health, modelling and risk). Student interviews highlight that trust between colleagues and supervisors, and the role of spaces for interaction (joint study sites, cluster group meetings, shared offices etc.) are important for joint work. Graduate analysis shows that students develop skills and confidence to work across disciplines through collaborating on their doctoral research. Working collaboratively during the doctorate appears to be strongly correlated with continuing to work in this way after graduation.

The Basque Colorectal Cancer Screening Programme began in 2009 and the implementation has been complete since 2013. Faecal immunological testing was used for screening in individuals between 50 and 69 years old. Colorectal Cancer in Basque country is characterized by unusual epidemiological features given that Colorectal Cancer incidence is similar to other European countries while adenoma prevalence is higher. The object of our study was to economically evaluate the programme via cost-effectiveness and budget impact analyses with microsimulation models. We applied the Microsimulation Screening Analysis (MISCAN)-Colon model to predict trends in Colorectal Cancer incidence and mortality and to quantify the short- and long-term effects and costs of the Basque Colorectal Cancer Screening Programme. The model was calibrated to the Basque demographics in 2008 and age-specific Colorectal Cancer incidence data in the Basque Cancer Registry from 2005 to 2008 before the screening begun. The model was also calibrated to the high adenoma prevalence observed for the Basque population in a previously published study. The multi-cohort approach used in the model included all the cohorts in the programme during 30 years of implementation, with lifetime follow-up. Unit costs were obtained from the Basque Health Service and both cost-effectiveness analysis and budget impact analysis were carried out. The goodness-of-fit of the model adaptation to observed programme data was evidence of validation. In the cost-effectiveness analysis, the savings from treatment were larger than the added costs due to screening. Thus, the Basque programme was dominant compared to no screening, as life expectancy increased by 29.3 days per person. The savings in the budget analysis appeared 10 years after the complete implementation of the programme. The average annual budget was €73.4 million from year 2023 onwards. This economic evaluation showed a screening intervention with a major health gain that also produced net savings when a long follow-up was used to capture the late economic benefit. The number of colonoscopies required was high but remain within the capacity of the Basque Health Service. So far in Europe, no other population Colorectal Cancer screening programme has been evaluated by budget impact analysis.

The programme implements basic data processing and analytical functions, including display and drift-corrected accumulation of scanned planes, interactive and semi-automated definition of regions of interest (ROIs), and export of the ROIs' elemental and isotopic composition in graphical and text-based formats. Additionally, the programme offers new functions that were custom-designed to address the needs of environmental microbiologists. Specifically, it allows manual and automated classification of ROIs based on the information that is derived either from the nanoSIMS dataset itself (e.g. from labelling achieved by halogen in situ hybridization) or is provided externally (e.g. as a fluorescence in situ hybridization image). Moreover, by implementing post-processing routines coupled to built-in statistical tools, the programme allows rapid synthesis and comparative analysis of results from many different datasets. After validation of the programme, we illustrate how these new processing and analytical functions increase flexibility, efficiency and depth of the nanoSIMS data analysis. Through its custom-made and open-source design, the programme provides an efficient, reliable and easily expandable tool that can help a growing community of environmental microbiologists and researchers from other disciplines process and analyse their nanoSIMS data. © 2012 Society for Applied Microbiology and Blackwell Publishing Ltd.

Implementation evaluations, also called process evaluations, involve studying the development of programmes, and identifying and understanding their strengths and weaknesses. Undertaking an implementation evaluation offers insights into evaluation objectives, but does not help the researcher develop a research strategy. During the implementation analysis of the UNAIDS drug access initiative in Chile, the strategic analysis model developed by Crozier and Friedberg was used. However, a major incompatibility was noted between the procedure put forward by Crozier and Friedberg and the specific characteristics of the programme being evaluated. In this article, an adapted strategic analysis model for programme evaluation is proposed. PMID:23526306

Sustainability of public social welfare programmes has long been of concern in development circles. An important aspect of sustainability is the ability to sustain the recurrent financial costs of programmes. A free maternal care programme (FMCP) was launched under the Ghana National Health Insurance Scheme (NHIS) in 2008 with a start-up grant from the British Government. This article examines claims expenditure under the programme and the implications for the financial sustainability of the programme, and the lessons for donor and public financing of social welfare programmes. Records of reimbursement claims for services and medicines by women benefitting from the policy in participating facilities in one sub-metropolis in Ghana were analysed to gain an understanding of the expenditure on this programme at facility level. National level financial inflow and outflow (expenditure) data of the NHIS, related to implementation of this policy for 2008 and 2009, were reviewed to put the facility-based data in the national perspective. A total of US$936 450.94 was spent in 2009 by the scheme on FMCP in the sub-metropolis. The NHIS expenditure on the programme for the entire country in 2009 was US$49.25 million, exceeding the British grant of US$10.00 million given for that year. Subsequently, the programme has been entirely financed by the National Health Insurance Fund. The rapidly increasing, recurrent demands on this fund from the maternal delivery exemption programme-without a commensurate growth on the amounts generated annually-is an increasing threat to the sustainability of the fund. Provision of donor start-up funding for programmes with high recurrent expenditures, under the expectation that government will take over and sustain the programme, must be accompanied by clear long-term analysis and planning as to how government will sustain the programme.

Objective To measure the cost effectiveness of systematic photographic screening for sight threatening diabetic eye disease compared with existing practice. Design Cost effectiveness analysis Setting Liverpool. Subjects A target population of 5000 diabetic patients invited for screening. Main outcome measures Cost effectiveness (cost per true positive) of systematic and opportunistic programmes; incremental cost effectiveness of replacing opportunistic with systematic screening. Results Baseline prevalence of sight threatening eye disease was 14.1%. The cost effectiveness of the systematic programme was £209 (sensitivity 89%, specificity 86%, compliance 80%, annual cost £104 996) and of the opportunistic programme was £289 (combined sensitivity 63%, specificity 92%, compliance 78%, annual cost £99 981). The incremental cost effectiveness of completely replacing the opportunistic programme was £32. Absolute values of cost effectiveness were highly sensitive to varying prevalence, sensitivity and specificity, compliance, and programme size. Conclusion Replacing existing programmes with systematic screening for diabetic eye disease is justified. PMID:10856062

Development of a competency mapping tool for undergraduate professional degree programmes, using mechanical engineering as a case study

2018-01-01

Mapping the curriculum of a professional degree to the associated competency standard ensures graduates have the competence to perform as professionals. Existing approaches to competence mapping vary greatly in depth, complexity, and effectiveness, and a standardised approach remains elusive. This paper describes a new mapping software tool that streamlines and standardises the competency mapping process. The available analytics facilitate ongoing programme review, management, and accreditation. The complete mapping and analysis of an Australian mechanical engineering degree programme is described as a case study. Each subject is mapped by evaluating the amount and depth of competence development present. Combining subject results then enables highly detailed programme level analysis. The mapping process is designed to be administratively light, with aspects of professional development embedded in the software. The effective competence mapping described in this paper enables quantification of learning within a professional degree programme, and provides a mechanism for holistic programme improvement.

[Participant structure and economic benefit of prevention bonus programmes in company health insurance funds].

PubMed

Friedrichs, M; Friedel, H; Bödeker, W

2009-10-01

This study investigates differences in sex, age, and educational level between participants and non-participants of prevention bonus programmes. The differences in the utilisation of drugs, hospital care, and sickness absence before the start of the programmes between these groups are also shown. Finally the economic benefit of the health insurance funds attributed to these programmes is estimated. Data from some 5.2 million insured subjects of 74 company health insurance funds in Germany were linked to information on enrollment into a prevention bonus programme anonymously. In a descriptive analysis the differences in the sociodemographic patterns between both groups are shown as well as the differences in costs to the health insurances in the three sectors mentioned above. The benefit to the health insurance funds is estimated by means of an analysis of covariance. Prevention bonus programmes yields an annual benefit of at least 129 euro per participant. Men aged 40 and older and women aged 30 and older are more likely to opt into such a programme. The same is true for persons with a higher educational level. There are only few differences in health-care utilisation between the participants and non-participants of the programmes before enrollment. Only 1.4% of all insured persons participated in the programmes. There is at least a short-term gain to both involved parties: the insured and the health insurance funds. The programmes are not dominated by deadweight effects. Long-term effects and effectiveness of prevention bonus programmes still have to be investigated. Copyright Georg Thieme Verlag KG Stuttgart .

A practical approach was developed to assess and compare the effects of five short road safety education (RSE) programmes for young adolescents that does not rely on injury or crash data but uses self reported behaviour. Questionnaires were administered just before and about one month after participation in the RSE programmes, both to youngsters who had participated in a RSE programme, the intervention group, and to a comparable reference group of youngsters who had not, the reference group. For each RSE programme, the answers to the questionnaires in the pre- and post-test were checked for internal consistency and then condensed into a single safety score using categorical principal components analysis. Next, an analysis of covariance was performed on the obtained safety scores in order to compare the post-test scores of the intervention and reference groups, corrected for their corresponding pre-test scores. It was found that three out of five RSE programmes resulted in significantly improved self-reported safety behaviour. However, the proportions of participants that changed their behaviour relative to the reference group were small, ranging from 3% to 20%. Comparisons among programme types showed cognitive approaches not to differ in effect from programmes that used fear-appeal approaches. The method used provides a useful tool to assess and compare the effects of different education programmes on self-reported behaviour. Copyright © 2014 Elsevier Ltd. All rights reserved.

Globalization is having an ever growing impact on the field of vaccine production and distribution in the world and domestically. In this article we examine the impact of taking a strategic approach to vaccination programmes by all the relevant actors: WHO, UNICEF, national immunization programmes, and vaccine manufacturers and distributors. The review of the relevant literature indicates that there are commonalities to the worldwide vaccination programmes. A comparative analysis of various vaccination strategies recommended by WHO and the immunization calendars of certain European countriesis made as well as an analysis of the Serbian vaccination programme. New and more expensive vaccines will continue to appear on the market in increasingly short periods of time.

Costs and outcomes of an intervention programme for offenders with personality disorders.

PubMed

Barrett, Barbara; Byford, Sarah

2012-04-01

The dangerous severe personality disorder programme was developed in high secure prisons and hospitals at great expense to identify and treat the most dangerous offenders with personality disorders. To evaluate whether the long-term costs of the programme are greater or less than the long-term outcomes. We used a Markov decision model with a cost-effectiveness analysis to determine the incremental cost of the programme per serious offence prevented and a cost-offset analysis to consider whether monetary benefits were greater than costs. Costs were consistently higher for the intervention programme and the cost per serious offence prevented was over £2 million, although there was some evidence that adjustments to the programme could lead to similar interventions becoming cost-effective. Little evidence was found to support the cost-effectiveness of the intervention programme for offenders with personality disorders, although delivery of the programme in a lower-cost prison would probably yield greater benefits than costs. There are frequent calls for mentally disordered offenders to be detained in secure hospitals rather than prisons; however, if reoffending remains the outcome of interest for policy makers, it is likely that the costs of detention in hospital will remain greater than the benefits for dangerous offenders with a personality disorder.

Two compounds of molybdate with 2, 2'-bipy and [MoO3]: [(2, 2'-bipy)2 (MoO3)3]n (I) and [(2, 2'-bipy) (MoO3)]n (II) were successfully synthesized by hydrothermal synthesis method with programmable temperature control. In order to clarify the relationship between the structure and spectroscopy of these two compounds, both of them were characterized by means of X-ray powder diffraction (XRD), Fourier transform infrared spectra(FTIR), thermal perturbation 2D-IR correlation spectrum (2D-IR COS), thermogravimetric analysis(TGA), scanning electron microscopy(SEM), High temperature infrared analysis, UV-Vis DRS adsorption spectra and solid fluorescence spectrum to investigate the relationship between structure and properties of the title compounds. The powder XRD patterns of the complexes are well matched with the simulation based on single-crystal analysis, which indicate that compound I and II are in a pure phase. The characteristics of vibration frequency of FTIR and thermal perturbation relative spectral response of 2D-IR peak is consistent with thecompound I and II structure analysis. The synchronous and asynchronous correlation 2D-IR spectra of compounds also identified the compounds I and II molybdenum-oxygen cluster skeletons sequencing of vibration intensity change with temperature consistent with the high temperature infrared analysis. Through the TGA and high temperature infrared analysis it was found that the decomposition temperature was more than 300 degrees C and maximum weight losses rates above 800 degrees C, which suggest that they have good thermal stability. According to the UV-Vis DRS spectrum of the compound I and II there exists a wide ultraviolet absorption band in a range of 225 to 350 nm. The compound I and II steady-state fluorescence spectrum under the excitation of 277 and 295 nm respectively revealed compound I and II have the strongest emission peak at 460 and 480 nm respectively. This paper illustrates the coordination situation of these two compounds, and reveals the inherent law of valence electrons in molecule energy level transition. In the meantime it was verified that the weak interaction not only plays a role of stability in the frame of the structure of the complexes, but also plays an important role in heat resistance.

Situational analysis of infant and young child nutrition policies and programmatic activities in Mali.

Progress towards reducing mortality and malnutrition among children <5 years of age has been less than needed to achieve related Millennium Development Goals. Therefore, several international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel', starting with a situational analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of the situational analysis are to compile, analyse and interpret available information on infant and young child feeding, and the nutrition situation of children <2 years of age in Mali, as one of the six targeted countries. Between June and September 2008, key informants responsible for conducting IYCN-related activities in Mali were interviewed, and 117 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, screening and management of acute malnutrition, prevention of mother-to-child transmission of HIV, food security, and hygienic practices. Most of the key IYCN topics were addressed in national policies, training materials, and programme documents. Information on the national coverage and impact of these programmes is generally not available. Exclusive breastfeeding (<6 months) has increased in Mali, but no studies identified the contributors to this increase. Despite improvements in breastfeeding practices, optimal infant, and young child feeding is still practiced among too few young children in Mali. Several research articles were identified, but few of these were linked to programme development. Some programme monitoring and evaluation reports were available, but few of these were rigorous enough to identify whether IYCN-specific programme components were implemented as designed or were achieving desired outcomes. Therefore, we could not confirm which programmes contributed to reported improvements. Monitoring of programmes managing malnutrition identified gaps in human and institutional capacities to fully carry out intended interventions and the government has recognized the overall lack of adequate numbers of health care providers to carry out necessary programmes in Mali, of which nutrition programmes are a part. The policy and programme framework is well established for support of optimal IYCN practices, but greater resources and capacity building are needed to: (i) conduct necessary research to adapt training materials and programme protocols to programmatic needs; (ii) implement rigorous monitoring and evaluation that identify effective programme components; and (iii) apply these findings in developing, expanding, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

Wakeling, Judy; Ferguson, Julie; Kennedy, Susan

2016-01-01

This paper summarises the evaluation of a pilot programme introduced by NHS Education for Scotland to provide education and skills training for nurses new to general practice. The programme was developed through extensive consultation with existing general practice nurses and was educationally accredited by the Royal College of General Practitioners and the Royal College of Nursing in 2013. Twelve nurses embarked upon the programme 2012-2013 and nine completed it. The programme was extensively evaluated through questionnaires (with supervisors, practice staff and participants), analysis of programme documentation and interviews with participants. Based on the evaluation feedback, alterations have been made to subsequent deliveries of the programme. These include removing some topic areas and lengthening the programme by three months. The programme continues to be successfully delivered and evaluation is ongoing to ensure it continues to meet nurses' needs.

2014-04-01

The most widely implemented offending behaviour programme in the United Kingdom was Enhanced Thinking Skills (ETS), a cognitive-behavioural group intervention that aimed to develop participant's general cognitive skills. A new offending behaviour programme has been developed to replace ETS: the Thinking Skills Programme (TSP). This study reports an evaluation of the effectiveness of TSP using psychometric assessments. Phasing of the two programmes created an opportunity to compare the two programmes consecutively. Forty participants, 20 from each programme, completed a range of psychometric measures to examine cognition, attitudes, and thinking styles. Analysis of pre- and post-programme psychometric results indicated that participants of TSP demonstrated improvements on 14 of the 15 scales, 9 of which were statistically significant. Effect sizes between pre-post results were generally greater for TSP than ETS, demonstrating that TSP had a more positive impact on the thinking styles and attitudes of participants than the ETS programme.

Dynamic control of shape can bring multifunctionality to devices. Soft materials capable of programmable shape change require localized control of the magnitude and directionality of a mechanical response. We report the preparation of soft, ordered materials referred to as liquid crystal elastomers. The direction of molecular order, known as the director, is written within local volume elements (voxels) as small as 0.0005 cubic millimeters. Locally, the director controls the inherent mechanical response (55% strain) within the material. In monoliths with spatially patterned director, thermal or chemical stimuli transform flat sheets into three-dimensional objects through controlled bending and stretching. The programmable mechanical response of these materials could yield monolithic multifunctional devices or serve as reconfigurable substrates for flexible devices in aerospace, medicine, or consumer goods.

Wallace, Sarah E; Evans, Kelli; Arnold, Taylor; Hux, Karen

2007-12-01

The researchers investigated rehabilitation experiences of brain injury (BI) survivors participating in a functional programme. The researchers used a phenomenological approach involving the collection of artifacts and the analysis of focus group discussions through horizontalizing statements, creating meaning units and clustering codes. Focus groups including staff members and survivors' relatives reported perceptions about the programme and survivors' experiences; programme artifacts (e.g. survivors' schedules, website information) provided additional information. Survivors verified focus group responses and an analysis using five assessment measures served to validate positive functional changes among programme participants. Three general categories of themes emerged: components of functional therapy, programme/culture features supporting functional therapy and family members' and survivors' reactions to a functional programme. Sub-categories and themes provided details about issues central to functional BI treatment. The findings suggest that functional therapy programmes: (a) address family and survivors' goals, (b) occur in the community or real world, (c) are implemented by people in survivors' environments, (d) are collaborative, (e) focus on a positive culture, (f) build on basic skills, (g) allow exploration of discharge options, (h) preserve survivors' privacy and dignity and (i) recognize difficulties associated with transitioning from acute to post-acute rehabilitation.

Interventions to reduce the use of seclusion and restraint in inpatient psychiatric settings: what we know so far a review of the literature.

PubMed

Scanlan, Justin Newton

2010-07-01

In recent times, much attention has been focused on the reduction of seclusion and restraint in psychiatric settings. This paper analyzes evidence available from evaluations of single seclusion and/or restraint reduction programmes. A total of 29 papers were included in the review. Seven key strategy types emerged from the analysis: (i) policy change/leadership; (ii) external review/debriefing; (iii) data use; (iv) training; (v) consumer/family involvement; (vi) increase in staff ratio/crisis response teams; and (vii) programme elements/changes. Outcomes indicate that a range of reduction programmes are successful in reducing the frequency and duration of seclusion and restraint use, while at the same time maintaining a safe environment. The development of new seclusion and restraint reduction programmes should include strong leadership from local management; external seclusion and restraint review committees or post-incident debriefing and analysis; broad-based staff training and programme changes at a local level. Behavioural and cognitive-behavioural programmes appear to be very useful in child and adolescent services. Further systematic research should be conducted to more fully understand which elements of successful programmes are the most powerful in reducing incidents of seclusion and restraint.

A cost-effectiveness analysis of a residential radon remediation programme in the United Kingdom.

1999-12-01

As residential radon programmes of identification and remediation have proceeded, so questions have been raised about their costs and benefits. This study presents a generalizable model for estimating the cost-effectiveness of a radon mitigation programme using the methodological framework now considered appropriate in the economic evaluation of health interventions. Its use will help to inform future discussion of radon remediation and lung cancer prevention programmes. Data from Northamptonshire were analysed, resulting in a societal cost-effectiveness ratio of Pounds Sterling 13250 per life-year gained in 1997. The percentage of houses found to be over the action level, and the percentage of householders who decide to remediate are shown to be important parameters for the cost-effectiveness analysis. Questions are raised about the particular importance of perspective in this type of analysis and suggestions are made for future research directions.

2017-11-01

The scaling of physical quantities that characterize the shape and dynamics of the viscous and thermal boundary layers with respect to the Rayleigh number will be presented for three series of three-dimensional high-resolution direct numerical simulations of Rayleigh-Benard convection (RBC) in a closed cylindrical cell of aspect ratio one. The simulations have been conducted for convection in air at a Prandtl number Pr = 0.7, in liquid gallium at Pr = 0.021 and in liquid sodium at Pr = 0.005. Then we discuss three statistical analysis methods which have been developed to predict the transition of turbulent RBC into the ultimate regime. The methods are based on the large-scale properties of the velocity profile. All three methods indicate that the range of critical Rayleigh numbers is shifted to smaller magnitudes as the Prandtl number becomes smaller.

2015-02-01

The aim of this study was to conduct a cost-utility analysis of the Education, Self-management and Upper Limb Exercise Training in People with RA (EXTRA) programme compared with usual care. A within-trial incremental cost-utility analysis was conducted with 108 participants randomized to either the EXTRA programme (n = 52) or usual care (n = 56). A health care perspective was assumed for the primary analysis with a 36 week follow-up. Resource use information was collected on interventions, medication, primary and secondary care contacts, private health care and social care costs. Quality-adjusted life years (QALYs) were calculated from the EuroQol five-dimension three-level (EQ-5D-3L) questionnaire responses at baseline, 12 and 36 weeks. Compared with usual care, total QALYs gained were higher in the EXTRA programme, leading to an increase of 0.0296 QALYs. The mean National Health Service (NHS) costs per participant were slightly higher in the EXTRA programme (by £82), resulting in an incremental cost-effectiveness ratio of £2770 per additional QALY gained. Thus the EXTRA programme was cost effective from an NHS perspective when assessed against the threshold of £20 000-£30 000/QALY gained. Overall, costs were lower in the EXTRA programme compared with usual care, suggesting it was the dominant treatment option from a societal perspective. At a willingness-to-pay of £20 000/QALY gained, there was a 65% probability that the EXTRA programme was the most cost-effective option. These results were robust to sensitivity analyses accounting for missing data, changing the cost perspective and removing cost outliers. The physiotherapist-led EXTRA programme represents a cost-effective use of resources compared with usual care and leads to lower health care costs and work absence.

Neutron radiography in Indian space programme

NASA Astrophysics Data System (ADS)

Viswanathan, K.

1999-11-01

Pyrotechnic devices are indispensable in any space programme to perform such critical operations as ignition, stage separation, solar panel deployment, etc. The nature of design and configuration of different types of pyrotechnic devices, and the type of materials that are put in their construction make the inspection of them with thermal neutrons more favourable than any other non destructive testing methods. Although many types of neutron sources are available for use, generally the radiographic quality/exposure duration and cost of source run in opposite directions even after four decades of research and development. But in the area of space activity, by suitably combining the X-ray and neutron radiographic requirements, the inspection of the components can be made economically viable. This is demonstrated in the Indian space programme by establishing a 15 MeV linear accelerator based neutron generator facility to inspect medium to giant solid propellant boosters by X-ray inspection and all types of critical pyro and some electronic components by neutron radiography. Since the beam contains unacceptable gamma, transfer imaging technique has been evolved and the various parameters have been optimised to get a good quality image.

Thermal stability of poly(ethylene-co-vinyl acetate) based materials

DOE PAGES

Patel, Mogon; Pitts, Simon; Beavis, Peter; ...

2013-03-26

The thermal stability properties of poly (ethylene-co-vinyl acetate) composites have been studied in support of our core programmes in materials qualification and life assessment. The material is used as a binder phase for boron particles in highly filled (70 wt %) composites. Our studies show that the uncured resin readily accumulates acetic acid through hydrolysis of the pendent acetate groups which alters the acidity (pH) of the material. Thermal desorption studies in combination with gas-chromatography-mass spectrometry show that the resin readily evolves acetic acid when thermally aged to temperatures up to 75°C. Gel Permeation Chromatography (GPC) suggests that thermal ageingmore » induces a gradual reduction in resin molecular weight and confirms the susceptibility of the material to chain scission. Heating at elevated temperatures in excess of 300oC is required to induce significant changes in the carbon skeleton through deacetylation and dehydration processes and the production of unsaturated main chain double bonds. Overall, the mechanical response of these filled composites are found to be relatively complex with the extent of polymer-filler interactions possibly playing an important role in determining key engineering properties. Mechanical property studies confirm a small but significant decrease in modulus presumably linked to thermally induced chain scission of the EVA binder.« less

Breast cancer screening in the Basque Country has shown 20 % reduction of the number of BC deaths and an acceptable overdiagnosis level (4 % of screen detected BC). The aim of this study was to evaluate the breast cancer early detection programme in the Basque Country in terms of retrospective cost-effectiveness and budget impact from 1996 to 2011. A discrete event simulation model was built to reproduce the natural history of breast cancer (BC). We estimated for lifetime follow-up the total cost of BC (screening, diagnosis and treatment), as well as quality-adjusted life years (QALY), for women invited to participate in the evaluated programme during the 15-year period in the actual screening scenario and in a hypothetical unscreened scenario. An incremental cost-effectiveness ratio was calculated with the use of aggregated costs. Besides, annual costs were considered for budget impact analysis. Both population level and single-cohort analysis were performed. A probabilistic sensitivity analysis was applied to assess the impact of parameters uncertainty. The actual screening programme involved a cost of 1,127 million euros and provided 6.7 million QALYs over the lifetime of the target population, resulting in a gain of 8,666 QALYs for an additional cost of 36.4 million euros, compared with the unscreened scenario. Thus, the incremental cost-effectiveness ratio was 4,214€/QALY. All the model runs in the probabilistic sensitivity analysis resulted in an incremental cost-effectiveness ratio lower than 10,000€/QALY. The screening programme involved an increase of the annual budget of the Basque Health Service by 5.2 million euros from year 2000 onwards. The BC screening programme in the Basque Country proved to be cost-effective during the evaluated period and determined an affordable budget impact. These results confirm the epidemiological benefits related to the centralised screening system and support the continuation of the programme.

Operation Installation (OI), a community-based smoke alarm installation programme in Dallas, Texas, targets houses in high-risk urban census tracts. Residents of houses that received OI installation (or programme houses) had 68% fewer medically treated house fire injuries (non-fatal and fatal) compared with residents of non-programme houses over an average of 5.2 years of follow-up during an effectiveness evaluation conducted from 2001 to 2011. To estimate the cost-benefit of OI. A mathematical model incorporated programme cost and effectiveness data as directly observed in OI. The estimated cost per smoke alarm installed was based on a retrospective analysis of OI expenditures from administrative records, 2006-2011. Injury incidence assumptions for a population that had the OI programme compared with the same population without the OI programme was based on the previous OI effectiveness study, 2001-2011. Unit costs for medical care and lost productivity associated with fire injuries were from a national public database. From a combined payers' perspective limited to direct programme and medical costs, the estimated incremental cost per fire injury averted through the OI installation programme was $128,800 (2013 US$). When a conservative estimate of lost productivity among victims was included, the incremental cost per fire injury averted was negative, suggesting long-term cost savings from the programme. The OI programme from 2001 to 2011 resulted in an estimated net savings of $3.8 million, or a $3.21 return on investment for every dollar spent on the programme using a societal cost perspective. Community smoke alarm installation programmes could be cost-beneficial in high-fire-risk neighbourhoods. Published by the BMJ Publishing Group Limited.

The PRISMA (PRecursore IperSpettrale della Missione Applicativa) Programme is an ASI (Agenzia Spaziale Italiana) hyperspectral mission for Earth observation based on a mono-payload single satellite: an Italian Consortium is in charge to realize the mission; Selex ES has the full responsibility of the hyperspectral payload composed by a high spectral resolution spectrometer optically integrated with a medium resolution panchromatic camera. The optical design permits to cover the wavelength range from 400 to 2500 nm and it is based on high transmittance optical assemblies, including a reflective common telescope in Three-Mirror Anastigmat (TMA) configuration, a single slit aperture, a panchromatic camera (700-900 nm) and a spectrometer having two channels (VNIR and SWIR), each one using an suitable prism configuration and spectrally separated by a beam splitter, conceived to minimize the number of optical elements. High performance MCT-based detectors represent the core of the instrument. To provide the required data quality for the entire mission lifetime (5 years), an accurate and stable calibration unit (radiometric and spectral) is integrated, for the in-flight instrument calibration. The thermal design has been based on a passive cooling system: a double stage radiator, suitable oriented and protected from unwanted heat fluxes, high performance heat pipes and an operational heaters network represent the solution adopted to achieve the required thermal stability.

The Bologna Process aims, amongst other things, to improve the mobility of Students within the EU. Student mobility is supported through programmes such as ERASMUS, and the success of these programmes is measured against quality and quantity of Student mobility within the European Union. This study aimed at establishing, from the students' perspective, the benefits of these programmes. To this purpose, 7 Students who were involved in a German-Finnish exchange programme were interviewed. This population was chosen, because they represented the largest group of students going to the same host university, and were influenced by the same variables, such as language difficulties and climatic conditions. The main objective of this study was to determine whether the educational and personal needs of the students were met during their exchange programme. The data analysis was done using Mayring's content analysis method. The results showed that successful mobility at student level, could lead to a diffusion of knowledge and skills between different countries. It was also found that the students indicated that their personal and educational needs were met irrespective of the language difficulties they experienced.

Identifying impact areas of nursing leadership development programmes is needed to determine if there are measureable effects on participants. These impact areas help to identify measures to substantiate the benefits of nursing leadership programmes for organization leaders making decisions about support and implementation of such opportunities for their emerging leaders. Using mixed qualitative/quantitative methods, the impact of a nursing leadership development programme, the Amy V. Cockcroft Fellowship, is examined to determine if there are measureable influences. Themes of four areas of impact: improved conflict resolution/negotiation skills, communication skills, personal development and career action or change were identified through content analysis. These themes provide the basis for creating measureable indicators for nursing organizations to use in determining the value of nursing leadership development programmes such as the Amy V. Cockcroft Fellowship. Based on the findings established in this research article, nurse managers can focus on developing themselves and their peer groups through nursing leadership development programmes to prepare for leading in the present and future healthcare environment. © 2012 Blackwell Publishing Ltd.

While existing research indicates that housing improvements are associated with health improvements, less is known about the wider social and health benefits of meeting national housing standards, as well as those of their specific constituent measures. This study evaluates the impacts of a managed housing upgrade programme through a repeated cross-sectional survey design. A five-wave repeated cross-sectional survey was conducted over a seven-year period from 2009 to 2016 (n = 2075; n = 2219; n = 2015; n = 1991; and n = 1709, respectively). The study followed a managed upgrade programme designed to meet a national social housing standard over an extended period. The data were analysed from a multilevel perspective to take account of the time-dependent nature of the observations and differences in socio-demographic composition. The installation of the majority of individual housing measures (new windows and doors; boilers; kitchens; bathrooms; electrics; loft insulation; and cavity/external wall insulation) were associated with improvements in several social (housing suitability, satisfaction, and quality; thermal comfort and household finances) and health (mental, respiratory and general health) outcomes; and analyses showed relationships between the number of measures installed and the total amount invested on the one hand and the social and health outcomes on the other. There were however a few exceptions. Most notably, the installation of cavity wall insulation was associated with poorer health outcomes, and did not lead to better social outcomes. Also, no association was found between the number of measures installed and respiratory health. The study suggests that substantial housing investments through a managed upgrade programme may result in better social and health outcomes, and that the size of the improvements are proportionate to the number of measures installed and amount invested. However, there may be risks associated with specific measures; and more attention is needed for mechanical ventilation when upgrading energy efficiency of houses through fabric work. In addition to providing new evidence regarding the wider social and health outcomes, the study provides an analytical approach to evaluate upgrade programmes that are delivered over multiple years.

OBJECTIVE: To develop a methodology and an instrument that allow the simultaneous rapid and systematic examination of the broad public health context, the health care systems, and the features of disease-specific programmes. METHODS: Drawing on methodologies used for rapid situational assessments of vertical programmes for tackling communicable disease, we analysed programmes for the control human of immunodeficiency virus (HIV) and their health systems context in three regions in the Russian Federation. The analysis was conducted in three phases: first, analysis of published literature, documents and routine data from the regions; second, interviews with key informants, and third, further data collection and analysis. Synthesis of findings through exploration of emergent themes, with iteration, resulted in the identification of the key systems issues that influenced programme delivery. FINDINGS: We observed a complex political economy within which efforts to control HIV sit, an intricate legal environment, and a high degree of decentralization of financing and operational responsibility. Although each region displays some commonalities arising from the Soviet traditions of public health control, there are considerable variations in the epidemiological trajectories, cultural responses, the political environment, financing, organization and service delivery, and the extent of multisectoral work in response to HIV epidemics. CONCLUSION: Within a centralized, post-Soviet health system, centrally directed measures to enhance HIV control may have varying degrees of impact at the regional level. Although the central tenets of effective vertical HIV programmes may be present, local imperatives substantially influence their interpretation, operationalization and effectiveness. Systematic analysis of the context within which vertical programmes are embedded is necessary to enhance understanding of how the relevant policies are prioritized and translated to action.

This paper reports analysis of the impact of Kenya’s Cash Transfer for Orphans and Vulnerable Children Programme on the household decisions on productive activities using data from a randomized experimental design. Results show that the programme had a positive and significant impact on food consumption coming from home production, accumulation of productive assets, especially on the ownership of small livestock and on formation of nonfarm enterprise, especially for females. The programme has provided more flexibility to families in terms of labour allocation decisions, particularly for those who are geographically isolated. The programme was also found to have reduced child labour, an important objective of the programme. However we find very little impact of the programme on direct indicators of crop production.

A selectable one-dimensional ((1)D) or two-dimensional ((2)D) gas chromatography-mass spectrometry (GC-MS) system coupled with flame ionization detector (FID) and olfactory detection port (ODP) was employed in this study to analyze perfume oil and fragrance in shower gel. A split/splitless (SSL) injector and a programmable temperature vaporization (PTV) injector are connected via a 2-way splitter of capillary flow technology (CFT) in this selectable (1)D/(2)D GC-MS/FID/ODP system to facilitate liquid sample injections and thermal desorption (TD) for stir bar sorptive extraction (SBSE) technique, respectively. The dual-linked injectors set-up enable the use of two different injector ports (one at a time) in single sequence run without having to relocate the (1)D capillary column from one inlet to another. Target analytes were separated in (1)D GC-MS/FID/ODP and followed by further separation of co-elution mixture from (1)D in (2)D GC-MS/FID/ODP in single injection without any instrumental reconfiguration. A (1)D/(2)D quantitative analysis method was developed and validated for its repeatability - tR; calculated linear retention indices (LRI); response ratio in both MS and FID signal, limit of detection (LOD), limit of quantitation (LOQ), as well as linearity over a concentration range. The method was successfully applied in quantitative analysis of perfume solution at different concentration level (RSD≤0.01%, n=5) and shower gel spiked with perfume at different dosages (RSD≤0.04%, n=5) with good recovery (96-103% for SSL injection; 94-107% for stir bar sorptive extraction-thermal desorption (SBSE-TD).

2013-11-01

Systematic analysis of STD programme data contributes to a national portrait of sexually transmitted disease (STD) prevention activities, including research and evaluation specifically designed to optimise programme efficiency and impact. We analysed the narrative of the 2009 annual progress reports of the US Comprehensive STD Prevention Systems cooperative agreement for 58 STD programmes, concentrating on programme characteristics and partnerships. Programmes described 516 unique partnerships with a median of seven organisations cited per STD programme. Non-profit organisations (including service providers) were most frequently cited. Higher gonorrhoea morbidity was associated with reporting more partnerships; budget problems were associated with reporting fewer. Challenges to engaging in partnerships included budget constraints, staff turnover and low interest. Data provide a source of information for judging progress in programme collaboration and for informing a sustained programme-focused research and evaluation agenda.

Clinical validation of robot simulation of toothbrushing - comparative plaque removal efficacy

2014-01-01

Background Clinical validation of laboratory toothbrushing tests has important advantages. It was, therefore, the aim to demonstrate correlation of tooth cleaning efficiency of a new robot brushing simulation technique with clinical plaque removal. Methods Clinical programme: 27 subjects received dental cleaning prior to 3-day-plaque-regrowth-interval. Plaque was stained, photographically documented and scored using planimetrical index. Subjects brushed teeth 33–47 with three techniques (horizontal, rotating, vertical), each for 20s buccally and for 20s orally in 3 consecutive intervals. The force was calibrated, the brushing technique was video supported. Two different brushes were randomly assigned to the subject. Robot programme: Clinical brushing programmes were transfered to a 6-axis-robot. Artificial teeth 33–47 were covered with plaque-simulating substrate. All brushing techniques were repeated 7 times, results were scored according to clinical planimetry. All data underwent statistical analysis by t-test, U-test and multivariate analysis. Results The individual clinical cleaning patterns are well reproduced by the robot programmes. Differences in plaque removal are statistically significant for the two brushes, reproduced in clinical and robot data. Multivariate analysis confirms the higher cleaning efficiency for anterior teeth and for the buccal sites. Conclusions The robot tooth brushing simulation programme showed good correlation with clinically standardized tooth brushing. This new robot brushing simulation programme can be used for rapid, reproducible laboratory testing of tooth cleaning. PMID:24996973

Cost-effectiveness models for dental caries prevention programmes among Chilean schoolchildren.

PubMed

Mariño, R; Fajardo, J; Morgan, M

2012-12-01

This study aims to estimate the cost-effectiveness from a societal perspective of seven dental caries prevention programmes among schoolchildren in Chile: three community-based programmes: water-fluoridation, salt-fluoridation and dental sealants; and four school-based programmes: milk-fluoridation; fluoridated mouthrinses (FMR); APF-Gel, and supervised toothbrushing with fluoride toothpaste. Standard cost-effectiveness analysis methods were used. The costs associated with implementing and operating each programme, using a societal perspective, were identified and estimated. The comparator was non-intervention. Health outcomes were measured as dental caries averted over a 6-year period. Costs were estimated as direct treatment costs, programmes costs and costs of productivity losses as a result of each dental caries prevention programme. Incremental cost-effectiveness ratios were calculated for each programme. Sensitivity analyses were conducted over key parameters. Primary cost-effectiveness analysis (discounted) indicated that four programmes showed net social savings by the DMFT averted. These savings encompassed a range of values per diseased tooth averted; US$16.21 (salt-fluoridation), US$14.89 (community water fluoridation); US$14.78 (milk fluoridation); and US$8.63 (FMR). Individual programmes using an APF-Gel application, dental sealants, and supervised tooth brushing using fluoridated toothpaste, represent costs for the society per diseased tooth averted of US$21.30, US$11.56 and US$8.55, respectively. Based on cost required to prevent one carious tooth among schoolchildren, salt fluoridation was the most cost-effective, with APF-Gel ranking as least cost-effective. Findings confirm that most community/school-based dental caries interventions are cost-effective uses of society's financial resources. The models used are conservative and likely to underestimate the real benefits of each intervention.

2016-01-01

Introduction In response to a significant increase of measles cases and a high percentage of unvaccinated adolescents in New South Wales, Australia, a measles high school catch-up vaccination programme was implemented between August and December 2014. This study aimed to explore the factors affecting school-based supplementary immunization activities (SIAs) and to inform future SIA and routine school-based vaccination programme implementation and service provision. Methods Focus group analysis was conducted among public health unit (PHU) staff responsible for implementing the SIA catch-up programme. Key areas discussed were pre-programme planning, implementation, resources, consent materials, media activity and future directions for school vaccination programme delivery. Sessions were audio recorded, transcribed verbatim and reviewed. Thematic analysis was conducted to identify the major themes. Results Two independent focus groups with 32 participants were conducted in January 2015. Barriers to the SIA implementation included lead time, consent processes, interagency collaboration, access to the targeted cohort and the impact of introducing a SIA to an already demanding curriculum and school programme immunization schedule. A positive PHU school coordinator rapport and experience of PHU staff facilitated the implementation. Consideration of different approaches for pre-clinic vaccination status checks, student involvement in the vaccination decision, online consent, workforce sharing between health districts and effective programme planning time were identified for improving future SIA implementation. Conclusion Although many barriers to school programme implementation have been identified in this study, with adequate resourcing and lead time, SIAs implemented via a routine school vaccination programme are an appropriate model to target adolescents.

To assess the nature of community-based health programme experience in Iran, and use the results in order to advocate more friendly policies in community, academy and funding organisations. The qualitative study was done in 2010-11 at various locations in Iran using semi structural in-depth interviews with the principals and managers of programmes, and focus group discussions with volunteers and service users of 13 Community Based Health Programmes which were active for at least five years. A total of 21 in-depth interviews and 20 focus group discussions were conducted. Data analysis was based on deductive-inductive content analysis approach considering the pre-determined structure in accordance with the study questions. The participants' views were analysed within the main category of governance, including the three sub-categories of leadership, monitoring and evaluation, and resource mobilisation. According to the participants, governmental programmes have centralised decision-making and management processes and local volunteers have no role in selecting managers at different levels of a programme. Such programmes are funded by the governmental core resources. In non-government organisations, resources available for such purposes mainly come through charitable individuals, service delivery fees and profitable economical activities, financial participation of volunteers and by using other organisations' facilities. In most programmes, there were no systematic process for monitoring and evaluation. Community-based Health programmes in Iran need to be revised in line with the positive input.There is a need to have community-based units within the Ministry of Health and Medical Education and other relevant organisations.

To present the results of a strengths, weaknesses, opportunities and threats (SWOT) analysis used as part of a process aimed at reorganising services provided within a pediatric rehabilitation programme (PRP) in Quebec, Canada and to report the perceptions of the planning committee members regarding the usefulness of the SWOT in this process. Thirty-six service providers working in the PRP completed a SWOT questionnaire and reported what they felt worked and what did not work in the existing model of care. Their responses were used by a planning committee over a 12-month period to assist in the development of a new service delivery model. Committee members shared their thoughts about the usefulness of the SWOT. Current programme strengths included favourable organisational climate and interdisciplinary work whereas weaknesses included lack of psychosocial support to families and long waiting times for children. Opportunities included working with community partners, whereas fear of losing professional autonomy with the new service model was a threat. The SWOT results helped the planning committee redefine the programme goals and make decisions to improve service coordination. SWOT analysis was deemed as a very useful tool to help guide service reorganisation. SWOT analysis appears to be an interesting evaluation tool to promote awareness among service providers regarding the current functioning of a rehabilitation programme. It fosters their active participation in the reorganisation of a new service delivery model for pediatric rehabilitation.

Due to limited progress towards reducing mortality and malnutrition among children <5 years of age, an alliance of international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel,' starting with a situational analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of this analysis are to compile, analyse, and interpret available information on infant and child feeding and the nutrition situation of children <2 years of age in Niger, as one of the six targeted countries. Between August and November 2008, key informants responsible for conducting IYCN-related activities in Niger were interviewed, and 90 documents were examined on: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, prevention of mother-to-child transmission of HIV, management of acute malnutrition, food security, and hygienic practices. The results reported are limited by the availability of documents for review. Mortality rates are on track to reaching the Millennium Development Goal to reduce mortality among young children by two-thirds by 2015, but there has been no change in undernutrition, and total mortality rates are still high among young children. Nearly all of the key IYCN topics were addressed, specifically or generally, in national policy documents, training materials, and programmes. A national nutrition council meets regularly to coordinate programme activities nationally. Many of the IYCN-related programmes are intended for national coverage, but few reach this coverage. Monitoring and impact evaluations were conducted on some programmes, but few of these reported on whether the specific IYCN components of the programme were implemented as designed or compared outcomes with non-intervention sites. Human resources have been identified as inadequate to fully carry out nutrition programmes in Niger. Due to these limitations, we could not confirm whether the lack of progress in reducing malnutrition was due to ineffective or inadequately implemented programmes, though both of these were likely contributors. The policy framework is well established for the promotion of optimal IYCN practices, but greater resources and capacity building are needed to: (i) increase human capacities to carry out nutrition programmes; (ii) expand and track the implementation of evidence-based programmes nationally; (iii) improve and carry out monitoring and evaluation that identify effective and ineffective programmes; and (iv) apply these findings in developing, expanding, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

Experimental re-entry demonstrators are currently being developed in Europe, with the objective of increasing the technology readiness level (TRL) of technologies applicable to future reusable launch vehicles. Among these are the Pre-X programme, currently funded by CNES, the French Space Agency, and which is about to enter into development phase B, and the IXV, within the future launcher preparatory programme (FLPP) funded by ESA. One of the major technologies necessary for such vehicles is the thermal protection system (TPS), and in particular the ceramic matrix composites (CMC) based windward TPS. In support of this goal, technology maturation activities named "generic shingle" were initiated beginning of 2003 by SPS, under a CNES contract, with the objective of performing a test campaign of a complete shingle of generic design, in preparation of the development of a re-entry experimental vehicle decided in Europe. The activities performed to date include: the design, manufacturing of two C/SiC panels, finite element model (FEM) calculation of the design, testing of technological samples extracted from a dedicated panel, mechanical pressure testing of a panel, and a complete study of the attachment system. Additional testing is currently under preparation on the panel equipped with its insulation, seal, attachment device, and representative portion of cold structure, to further assess its behaviour in environments relevant to its application The paper will present the activities that will have been performed in 2006 on the prediction and preparation of these modal characterization, dynamic, acoustic as well as thermal and thermo-mechanical tests. Results of these tests will be presented and the lessons learned will be discussed.

The aim of the study was to develop a group-based self-management programme for individuals with chronic fatigue syndrome (CFS) by using the participants' experiences with the initial version of the programme, which intends to promote coping with the illness in a primary healthcare setting. An initial programme was developed, based on self-efficacy theory and the concepts of client-centred practice and empowerment. Subsequently, the programme was tested and further developed by drawing on the participants' experiences with the programme. Focus-group interviews were applied. The interviews were analysed using thematic analysis. The initial programme was found to be feasible, although several modifications regarding the content and practical organization of the programme were proposed. In line with the participants' experiences, the final self-management programme was developed, which includes short presentations of eight topics, exchange of experiences among participants, goal-setting, construction of action plans, and relaxation exercises, in addition to a meeting for relatives. The programme will be provided in eight biweekly sessions and be led by juxtaposed peer counsellors and occupational therapists. The effects of the final programme will be evaluated in a randomized controlled trial.

To address the growing burden of violence and injuries, especially in low- and middle-income countries, in 2007 the World Health Organization launched MENTOR-VIP, a global violence and injury prevention (VIP)-mentoring programme. The programme aims to develop human resource capacity through 12-month mentoring arrangements between individual VIP experts (mentors) and less-experienced injury practitioners (mentees). In this paper, we review the first five years of the programme (2007-2011) using a systems analysis and SWOT (Strengths, Weaknesses, Opportunities and Threats) frameworks, discuss programme findings and make recommendations. A well-defined programme with clear instructions, successful matching of mentorship pairs with similar interests and language, a formal accord agreement, institutional support and effective communication were identified as programme strengths. Overambitious projects, lack of funds and difficulties with communications were identified as programme weaknesses. Mentorship projects that require institutional permissions or resources could be potential threats to the success of mentorship. The study resulted in the four following recommendations to strengthen the programme: (1) institute additional steps in selection and matching mentor-mentee pair; (2) train mentors on e-mentoring; (3) conduct special orientation for mentees to the programme; and (4) maintain effective and open communication throughout the programme.

Global Fund grant programmes: an analysis of evaluation scores.

The Global Fund to Fight AIDS, Tuberculosis and Malaria evaluates programme performance after 2 years to help decide whether to continue funding. We aimed to identify the correlation between programme evaluation scores and characteristics of the programme, the health sector, and the recipient country. We obtained data on the first 140 Global Fund grants evaluated in 2006, and analysed 134 of these. We used an ordered probit multivariate analysis to link evaluation scores to different characteristics, allowing us to record the association between changes in those characteristics and the probability of a programme receiving a particular evaluation score. Programmes that had government agencies as principal recipients, had a large amount of funding, were focused on malaria, had weak initial proposals, or were evaluated by the accounting firm KPMG, scored lowest. Countries with a high number of doctors per head, high measles immunisation rates, few health-sector donors, and high disease-prevalence rates had higher evaluation scores. Poor countries, those with small government budget deficits, and those that have or have had socialist governments also received higher scores. Our results show associations, not causality, and they focus on evaluation scores rather than actual performance of the programmes. Yet they provide some early indications of characteristics that can help the Global Fund identify and monitor programmes that might be at risk. The results should not be used to influence the distribution of funding, but rather to allocate resources for oversight and risk management.

Contextual factors affecting task distribution in two participatory ergonomic interventions: a qualitative study.

PubMed

Dixon, Shane Michael; Theberge, Nancy

2011-11-01

This article provides an analysis of the evolution of the division of labour in participatory ergonomics (PE) programmes in two worksites. The analysis is based on interviews and field observations in the worksites. In both settings there was meaningful participation by both worker and management members of ergonomic change teams (ECTs) in the hazard assessment and solution identification stages, but as the teams moved to the implementation stage, worker representatives were marginalised and the participatory nature of the programmes was severely curtailed. The removal of workers from the process was the outcome of the interplay among the type of activities pursued in the implementation stage, the skills and knowledge required to carry out those activities, and workers' limited influence in the organisational hierarchies. Findings highlight the salience of the social context in which participatory programmes are located and the importance of examining participatory programmes as they evolve over time. STATEMENT OF RELEVANCE: This article contributes to a growing literature on the process and implementation of PE programmes. The article's focus on social and organisational factors that affect the division of labour and attention to the evolution of involvement over time extend current understandings of participation in ergonomics programmes.

Parents’ Participation in the Sexuality Education of Their Children in Rural Namibia: A Situational Analysis

Lukolo, Linda Ndeshipandula; van Dyk, Agnes

2015-01-01

Talking about sexuality has never been easy in most Namibians cultures and it seems that most parents feel uncomfortable and embarrassed to talk openly with their children about sexuality. They do not participate in the sexuality education of their children, because they believe they are unable to provide quality and adequate sexuality information due to their lack of knowledge about human sexuality or their perceived inability to explain what they do know. The ultimate purpose of this study was to develop, describe, implement and evaluate an educational programme to empower rural parents to participate in the sexuality education of their children. The study was designed to be qualitative, explorative, descriptive and contextual in nature. It was performed in three phases. Phase 1 consisted of a situational analysis to explore and describe how parents provide sexuality education. Phase 2 consisted of the development of a conceptual framework that facilitated the development of an educational programme. In phase 3 the programme was implemented and evaluated, recommendations were made and conclusions drawn. The main findings revealed two themes: factors influencing parental participation in their children’s sexuality education, and the need for parental participation in their children’s sexuality education. This article is part of series of three article stems from a study on the topic of sexuality education empowerment programme of rural parents in Namibia. The three articles have the following titles: one: parent’s participation in sexuality education of their children: a situational analysis; two: conceptual framework developments that facilitate the development of an educational programme and three: programme implementation and evaluation. This article dealt with parent’s participation in sexuality education of their children: a situational analysis. PMID:25560329

To determine the cost-effectiveness of a physical activity programme (Be Active) aimed at city-dwelling adults living in Birmingham, UK. Very little is known about the cost-effectiveness of public health programmes to improve city-wide physical activity rates. This paper presents a cost-effectiveness analysis that compares a physical activity intervention (Be Active) with no intervention (usual care) using an economic model to quantify the reduction in disease risk over a lifetime. Metabolic equivalent minutes achieved per week, quality-adjusted life years (QALYs) gained and healthcare costs were all included as the main outcome measures in the model. A cost-benefit analysis was also conducted using 'willingness-to-pay' as a measure of value. Under base-case assumptions-that is, assuming that the benefits of increased physical activity are sustained over 5 years, participation in the Be Active programme increased quality-adjusted life expectancy by 0.06 years, at an expected discounted cost of £3552, and thus the cost-effectiveness of Be Active is £400 per QALY. When the start-up costs of the programme are removed from the economic model, the cost-effectiveness is further improved to £16 per QALY. The societal value placed on the Be Active programme was greater than the operation cost therefore the Be Active physical activity intervention results in a net benefit to society. Participation in Be Active appeared to be cost-effective and cost-beneficial. These results support the use of Be Active as part of a public health programme to improve physical activity levels within the Birmingham-wide population.

Objective To assess whether the multitherapy antenatal education ‘CTLB’ (Complementary Therapies for Labour and Birth) Study programme leads to net cost savings. Design Cost analysis of the CTLB Study, using analysis of outcomes and hospital funding data. Methods We take a payer perspective and use Australian Refined Diagnosis-Related Group (AR-DRG) cost data to estimate the potential savings per woman to the payer (government or private insurer). We consider scenarios in which the intervention cost is either borne by the woman or by the payer. Savings are computed as the difference in total cost between the control group and the study group. Results If the cost of the intervention is not borne by the payer, the average saving to the payer was calculated to be $A808 per woman. If the payer covers the cost of the programme, this figure reduces to $A659 since the average cost of delivering the programme was $A149 per woman. All these findings are significant at the 95% confidence level. Significantly more women in the study group experienced a normal vaginal birth, and significantly fewer women in the study group experienced a caesarean section. The main cost saving resulted from the reduced rate of caesarean section in the study group. Conclusion The CTLB antenatal education programme leads to significant savings to payers that come from reduced use of hospital resources. Depending on which perspective is considered, and who is responsible for covering the cost of the programme, the net savings vary from $A659 to $A808 per woman. Compared with the average cost of birth in the control group, we conclude that the programme could lead to a reduction in birth-related healthcare costs of approximately 9%.

This report summarises opportunities in Europe for master's degree level training in health promotion. Using data available at www.HP-Source.net, 105 study programmes at 71 institutions, spread over 20 European countries, were identified that include health promotion as a main subject. The programmes were analysed along a number of dimensions, including title, learning objectives, curricula, learning and teaching methods, entry requirements, duration, accreditation, language(s) of instruction and participation in European educational structures. The present analysis reveals great diversity along all these dimensions, but also several clusters of programmes that offer quite similar education in health promotion. Of special interest is the range of options available in Europe for length of study, ranging from one to two years, with part-time as well as full-time options.

An in-depth analysis of the publications from 8414 distinct scheduled VLT observing programmes between April 1999 and March 2015 (Periods 63 to 94) is presented. The productivity by mode (Visitor or Service Mode) and type (Normal and Large, Guaranteed Time, Target of Opportunity, Director's Discretionary Time) are examined through their publication records. We investigate how Service Mode rank classes impact the scientific return. Several results derive from this study: Large Programmes result in the highest productivity, whereas only about half of all scheduled observing programmes produce a refereed publication. Programmes that result in a publication yield on average two refereed papers. B rank class Service Mode Programmes appear to be slightly less productive. Follow-up studies will investigate in more detail the parameters that influence the productivity of the Observatory.

Observation of the Spin Nernst Effect in Platinum

NASA Astrophysics Data System (ADS)

Goennenwein, Sebastian

Thermoelectric effects - arising from the interplay between thermal and charge transport phenomena - have been extensively studied and are considered well established. Upon taking into account the spin degree of freedom, however, qualitatively new phenomena arise. A prototype example for these so-called magneto-thermoelectric or spin-caloritronic effects is the spin Seebeck effect, in which a thermal gradient drives a pure spin current. In contrast to their thermoelectric counterparts, not all the spin-caloritronic effects predicted from theory have yet been observed in experiment. One of these `missing' phenomena is the spin Nernst effect, in which a thermal gradient gives rise to a transverse pure spin current. We have observed the spin Nernst effect in yttrium iron garnet/platinum (YIG/Pt) thin film bilayers. Upon applying a thermal gradient within the YIG/Pt bilayer plane, a pure spin current flows in the direction orthogonal to the thermal drive. We detect this spin current as a thermopower voltage, generated via magnetization-orientation dependent spin transfer into the adjacent YIG layer. Our data shows that the spin Nernst and the spin Hall effect in in Pt have different sign, but comparable magnitude, in agreement with first-principles calculations.

Phase change materials, changing from solid to liquid and vice versa, are capable of storing and releasing a large amount of thermal energy during the phase change, and thus hold promise for numerous applications including thermal protection of electronic devices. Shaping these materials into microspheres for additional fascinating properties is efficient but challenging. In this regard, a novel phase change microsphere with the design for electrical-regulation and thermal storage/release properties was fabricated via the combination of monodispersed graphene aerogel microsphere (GAM) and phase change paraffin. A programmable method, i.e., coupling ink jetting-liquid marbling-supercritical drying (ILS) techniques, was demonstrated to produce monodispersed graphene aerogel microspheres (GAMs) with precise size-control. The resulting GAMs showed ultralow density, low electrical resistance, and high specific surface area with only ca. 5% diameter variation coefficient, and exhibited promising performance in smart switches. The phase change microspheres were obtained by capillary filling of phase change paraffin inside the GAMs and exhibited excellent properties, such as low electrical resistance, high latent heat, well sphericity, and thermal buffering. Assembling the phase change microsphere into the microcircuit, we found that this tiny device was quite sensitive and could respond to heat as low as 0.027 J.

Transverse crack initiation under combined thermal and mechanical loading of Fibre Metal Laminates and Glass Fibre Reinforced Polymers

The paper describes a temperature-dependent extension of the classical laminate theory (CLT) that may be used to predict the mechanical behaviour of Fibre Metal Laminates (FML) at cryogenic conditions, including crack initiation. FML are considered as a possible alternative class of structural materials for the transport and storage of liquified gasses such as LNG. Combining different constituents in a laminate opens up the possibility to enhance its functionality, e.g. offering lower specific weight and increased damage tolerance. To explore this possibility, a test programme is underway at the University of Twente to study transverse crack initiation in different material combinations under combined thermal and mechanical loading. Specifically, the samples are tested in a three-point bending experiment at temperatures ranging from 77 to 293 K. These tests will serve as a validation of the model presented in this paper which, by incorporating temperature-dependent mechanical properties and differential thermal expansion, will allow to select optimal material combinations and laminate layouts. By combining the temperature-dependent mechanical properties and the differential thermal contraction explicitly, the model allows for a more accurate estimate of the resulting thermal stresses which can then be compared to the strength of the constituent materials.

Space shuttle atmospheric revitalization subsystem/active thermal control subsystem computer program (users manual)

NASA Technical Reports Server (NTRS)

1973-01-01

A shuttle (ARS) atmosphere revitalization subsystem active thermal control subsystem (ATCS) performance routine was developed. This computer program is adapted from the Shuttle EC/LSS Design Computer Program. The program was upgraded in three noteworthy areas: (1) The functional ARS/ATCS schematic has been revised to accurately synthesize the shuttle baseline system definition. (2) The program logic has been improved to provide a more accurate prediction of the integrated ARS/ATCS system performance. Additionally, the logic has been expanded to model all components and thermal loads in the ARS/ATCS system. (3) The program is designed to be used on the NASA JSC crew system division's programmable calculator system. As written the new computer routine has an average running time of five minutes. The use of desk top type calculation equipment, and the rapid response of the program provides the NASA with an analytical tool for trade studies to refine the system definition, and for test support of the RSECS or integrated Shuttle ARS/ATCS test programs.

While HIV has had a major impact on health care in southern Africa, there are few data on its impact on acute malnutrition in children in the community. We report an analysis of outcomes in a large programme of community management of acute malnutrition in the south of Lusaka. Over 3 years, 68,707 assessments for undernutrition were conducted house-to-house, and children with severe acute malnutrition (SAM) or moderate acute malnutrition (MAM) were enrolled into either Outpatient Therapeutic Programme (OTP) or Supplementary Feeding Programme (SFP) respectively. Case records were analysed using tabulation and unconditional logistic regression. 1,859 children (889 boys, 970 girls; median age 16 months) with MAM (n = 664) or SAM (n = 1,195) were identified. Of 1,796 children whose parents consented to testing, 185 (10.3%) were HIV positive. Altogether 1,163 (62.6%) were discharged as recovered from acute malnutrition. Case fatality while in the programme was 4.2% in children with SAM and 0.5% in those with MAM (RR of SAM 10.9; 95%CI 3.4,34.8; P<0.0001), and higher in children with HIV infection (RR 5.2, 95%CI 2.9, 9.0; P<0.0001). In multivariate analysis, HIV (OR 5.2; 95%CI 2.6, 10.1; P<0.0001), MUAC <11.5 cm (OR 4.1; 95%CI 2.2, 7.4; P<0.0001) and the first year of the programme (OR 1.9; 95%CI 1.0, 3.4; P = 0.04) all increased mortality. Children with HIV infection who were able to initiate antiretroviral therapy had lower mortality (RR 0.23; 95%CI 0.10, 0.57; P = 0.0008). Our programme suggests that a comprehensive community malnutrition programme, incorporating HIV care, can achieve low mortality even in a population heavily affected by HIV.

The emergence of community health worker programmes in the late apartheid era in South Africa: An historical analysis

2010-01-01

There is re-emerging interest in community health workers (CHWs) as part of wider policies regarding task-shifting within human resources for health. This paper examines the history of CHW programmes established in South Africa in the later apartheid years (1970s–1994) – a time of innovative initiatives. After 1994, the new democratic government embraced primary healthcare (PHC), however CHW initiatives were not included in their health plan and most of these programmes subsequently collapsed. Since then a wide array of disease-focused CHW projects have emerged, particularly within HIV care. Thirteen oral history interviews and eight witness seminars were conducted in South Africa in April 2008 with founders and CHWs from these earlier programmes. These data were triangulated with written primary sources and analysed using thematic content analysis. The study suggests that 1970s–1990s CHW programmes were seen as innovative, responsive, comprehensive and empowering for staff and communities, a focus which respondents felt was lost within current programmes. The growth of these earlier projects was underpinned by the struggle against apartheid. Respondents felt that the more technical focus of current CHW programmes under-utilise a valuable human resource which previously had a much wider social and health impact. These prior experiences and lessons learned could usefully inform policy-making frameworks for CHWs in South Africa today. PMID:20638169

Schools are recognized as one of the most important settings for promoting social and emotional well-being among children and adolescents. This clustered randomized controlled trial evaluated Zippy's Friends, an international school-based emotional well-being programme, with 766 children from designated disadvantaged schools. The purpose of this study was to evaluate the immediate and long term impact of the programme and to determine the impact of implementation fidelity on programme outcomes. Teachers reported emotional literacy outcomes using the Emotional Literacy Checklist, and emotional and behavioural outcomes using the Strengths and Difficulties Questionnaire. Controlling for the hierarchical structure of the data, path analysis using structural equation modelling revealed that the programme had a significant positive impact on the children's emotional literacy scores including significant improvements in the subscale scores of self-awareness (P < 0.001), self-regulation (P < 0.01), motivation (P < 0.001) and social skills (P < 0.001) at post-intervention. These results were maintained at 12-month follow-up (P < 0.01). The programme, however, did not have a significant impact on children's emotional and behavioural problems. Analysis of programme fidelity indicated that high fidelity was directly related to improved emotional literacy scores at post-intervention. © The Author 2014. Published by Oxford University Press.

A shift in universities world wide in providing theoretical post graduate programmes of study underpinned by traditional assessment strategies to work based learning programmes supported by innovative assessment strategies is required if Higher education institutions are to effectively educate contemporary healthcare leaders. Concurrently generating the evidence to evaluate the effectiveness of educational programmes is required by commissioners of healthcare education (DH, 2010). This paper reports on the perceptions of twelve post graduate students attending a clinical leadership masters programme of their leadership development through analysis of the critical commentary provided by students as part of assessment strategy that utilised the Patchwork Text Assessment. Following a thematic content analysis six themes emerged: programme philosophy and its impact on the success of the Patchwork Text Assessment; leadership development targeted against leadership frameworks; application and applicability of learning to the students own healthcare organisation; integrating theory to practice through theoretical development and work based activities; the value of networking; and the importance of multi-professional reflective groups. This study has clearly demonstrated how the success of the Patchwork Text Assessment in promoting deep learning is determined by its integration into the overall philosophy of the programme. Concurrently systems needed to be in place to ensure that Patchwork text Assessment is operationalised effectively and embedded within the day to day management of the programme.

The emergence of community health worker programmes in the late apartheid era in South Africa: An historical analysis.

PubMed

There is re-emerging interest in community health workers (CHWs) as part of wider policies regarding task-shifting within human resources for health. This paper examines the history of CHW programmes established in South Africa in the later apartheid years (1970s-1994) - a time of innovative initiatives. After 1994, the new democratic government embraced primary healthcare (PHC), however CHW initiatives were not included in their health plan and most of these programmes subsequently collapsed. Since then a wide array of disease-focused CHW projects have emerged, particularly within HIV care. Thirteen oral history interviews and eight witness seminars were conducted in South Africa in April 2008 with founders and CHWs from these earlier programmes. These data were triangulated with written primary sources and analysed using thematic content analysis. The study suggests that 1970s-1990s CHW programmes were seen as innovative, responsive, comprehensive and empowering for staff and communities, a focus which respondents felt was lost within current programmes. The growth of these earlier projects was underpinned by the struggle against apartheid. Respondents felt that the more technical focus of current CHW programmes under-utilise a valuable human resource which previously had a much wider social and health impact. These prior experiences and lessons learned could usefully inform policy-making frameworks for CHWs in South Africa today. Copyright 2010 Elsevier Ltd. All rights reserved.

The aim of this study was to investigate child health-care coordinators' experiences of being a facilitator for the implementation of a new national child health-care programme in the form of a web-based national guide. The study was based on eight remote, online focus groups, using Skype for Business. A qualitative content analysis was performed. The analysis generated three categories: adapt to a local context, transition challenges and led by strong incentives. There were eight subcategories. In the latent analysis, the theme 'Being a facilitator: a complex role' was formed to express the child health-care coordinators' experiences. Facilitating a national guideline or decision support in a local context is a complex task that requires an advocating and mediating role. For successful implementation, guidelines and decision support, such as a web-based guide and the new child health-care programme, must match professional consensus and needs and be seen as relevant by all. Participation in the development and a strong bottom-up approach was important, making the web-based guide and the programme relevant to whom it is intended to serve, and for successful implementation. The study contributes valuable knowledge when planning to implement a national web-based decision support and policy programme in a local health-care context.

Honduras has made steady progress in expanding post-primary school coverage in recent years, but many rural communities still do not provide a middle (lower secondary) school. As a result, Honduras has implemented a number of middle school alternative programmes designed to meet the needs of at-risk populations throughout the country. This article analyses dropout in three of the four main alternative lower secondary school programmes in Honduras over a three-year period for a cohort of roughly 5,500 students. The results show that these programmes are indeed reaching a vulnerable population in the country, but dropout rates are generally very high - upwards of 50 per cent in some cases - between Grades 7 and 9. Furthermore, even in the control school comparison samples made up of formal lower secondary schools, about 25 per cent of children leave school between Grades 7 and 9. The authors' analysis includes propensity score matching (PSM) methods that make more focused comparisons between students in alternative programmes and control samples. These results show that dropout rates in alternative programmes are not much different than in control schools, and only significant in one programme comparison, when taking into account family background characteristics like socioeconomic status (SES). Multivariate analysis within alternative programme samples finds that attrition is lower in those learning centres which have adopted key features of formal schools, such as university-educated teachers. The results highlight the tremendous variation in the alternative middle school sector in terms of programme features, school quality and student outcomes, as well as the challenges of expanding this sector to meet the growing demand for lower secondary schooling in Honduras.

A cultural drama programme was designed for patients with dementia and was led by teachers trained in drama in education and storytelling. The focus was on dance, rhythm, song, storytelling and conversations. The aim of this study was to describe how a drama programme for patients with dementia and their caregivers was experienced by the caregivers. Twelve strategically selected patients, 10 women and two men, with moderate and severe dementia, and their seven female caregivers participated in the programme. Sessions were held for one and a half hour, weekly once for 2 months. A focus group interview was held with the caregivers 1 month after the programme had ended. The interview and analysis of data were carried out according to the principles of phenomenography. Two categories, 'interaction' and 'professional growth', and five subcategories emerged in the analysis. In these, the caregivers described how fellowship developed between the participants and how they shared joy and sorrow. The patients communicated with each other and the leaders, and the programme seemed to help the patients to remember and make associations with situations experienced earlier in their lives. The patients also showed knowledge and ability in things about which the caregivers were unaware until the time of the drama programme. In other daily life situations, the patients showed their feelings, both joy and sorrow, more openly, their self-confidence grew and they showed greater interest in their surroundings. The caregivers furthermore expressed that they felt confirmed in their roles as caregivers. The programme prompted them to reflect upon their roles as caregivers. In conclusion, a drama programme with cultural features seems to increase the quality of life in patients with dementia and strengthen the caregivers in their profession.

Introduction Case management allows us to respond to the complex needs of a vulnerable clientele through a structured approach that promotes enhanced interaction between partners. Syntheses on the subject converge towards a need for a better description of the relationships between programmes and their local context, as well as the characteristics of the clienteles and programmes that contribute to positive impacts. The purpose of this project is thus to describe and evaluate the case management programmes of four health and social services centres in the Saguenay-Lac- Saint-Jean region of Québec, Canada, in order to inform their improvement while creating knowledge on case management that can be useful in other contexts. Methods and analysis This research relies on a multiple embedded case study design based on a developmental evaluation approach. We will work with the case management programme for high users of hospital services of each centre. Three different units of analysis will be interwoven to obtain an in-depth understanding of each case, that is: (1) health and social services centre and local services network, (2) case management programme and (3) patients who are high users of services. Two strategies for programme evaluation (logic models and implementation analysis) will guide the mixed data collection based on qualitative and quantitative methods. This data collection will rely on: (1) individual interviews and focus groups; (2) participant observation; (3) document analysis; (4) clinical and administrative data and (5) questionnaires. Description and comparison of cases, and integration of qualitative and quantitative data will be used to guide the data analysis. Ethics and dissemination The study protocol was approved by the Ethics Research Boards of the four health and social services centres (HSSCs) involved. Findings will be disseminated by publications in peer-reviewed journals, conferences, and policy and practice partners in local and national government. PMID:25468510

To evaluate the clinical effectiveness of programmable valves compared with non-programmable valves of hydrocephalus. In this paper, the authors report a systematic review and meta-analysis of complications and revision rate for programmable valves and non-programmable implantation. Randomized or non-randomized controlled trials of hydrocephalus treated by programmable and non-programmable valves were considered for inclusion. Seven published reports of eligible studies involving 1702 participants meet the inclusion criteria. Compared with non-programmable, programmable valves had no significant difference in catheter-related complications [RR = 0.88, 95%CI (0.66,1.19), p = 0.10] and infection rate [RR = 1.25, 95%CI (0.92,1.69), p = 1.00]. There were significant differences in overall complications [RR = 0.80, 95%CI (0.67,0.96), p < 0.01], over-drainage or under-drainage complications [RR = 0.44, 95%CI (0.31,0.63), p < 0.01] and revision rate [RR = 0.56, 95%CI (0.45,0.69), p < 0.01] in favor of programmable valves. Although the studies seem to demonstrate a small advantage for the programmable shunts, the probable bias and the difficulties in patient selection are too important to make a general conclusion.

The Mars Analysis Correction Data Assimilation (MACDA) dataset version 1.0 contains the reanalysis of fundamental atmospheric and surface variables for the planet Mars covering a period of about three Martian years (late MY 24 to early MY 27). This four-dimensional dataset has been produced by data assimilation of retrieved thermal profiles and column dust optical depths from NASA's Mars Global Surveyor/Thermal Emission Spectrometer (MGS/TES), which have been assimilated into a Mars global climate model (MGCM) using the Analysis Correction scheme developed at the UK Meteorological Office.The MACDA v1.0 reanalysis is publicly available, and the NetCDF files can be downloaded from the archive at the Centre for Environmental Data Analysis/British Atmospheric Data Centre (CEDA/BADC). The variables included in the dataset can be visualised using an ad-hoc graphical user interface (the "MACDA Plotter") located at the following URL: http://macdap.physics.ox.ac.uk/The first paper about MACDA reanalysis of TES retrievals appeared in 2006, although the acronym MACDA was not yet used at that time. Ten years later, MACDA v1.0 has been used by several researchers worldwide and has contributed to the advancement of the knowledge about the martian atmosphere in critical areas such as the radiative impact of water ice clouds, the solsticial pause in baroclinic wave activity, and the climatology and dynamics of polar vortices, to cite only a few. It is therefore timely to review the scientific results obtained by using such Mars reference atmospheric reanalysis, in order to understand what priorities the user community should focus on in the next decade.MACDA is an ongoing collaborative project, and work funded by NASA MDAP Programme is currently undertaken to produce version 2.0 of the Mars atmospheric reanalysis. One of the key improvements is the extension of the reanalysis period to nine martian years (MY 24 through MY 32), with the assimilation of NASA's Mars Reconnaissance Orbiter/Mars Climate Sounder (MRO/MCS) retrievals of thermal and dust opacity profiles. MACDA 2.0 is also going to be based on an improved version of the underlying MGCM and an updated scheme to fully assimilate (radiative active) tracers, such as dust.

Multi-parameter fibre Bragg grating sensor-array for thermal vacuum cycling test

NASA Astrophysics Data System (ADS)

Cheng, L.; Ahlers, B.; Toet, P.; Casarosa, G.; Appolloni, M.

2017-11-01

Fibre Bragg Grating (FBG) sensor systems based on optical fibres are gaining interest in space applications. Studies on Structural Health Monitoring (SHM) of the reusable launchers using FBG sensors have been carried out in the Future European Space Transportation Investigations Programme (FESTIP). Increasing investment in the development on FBG sensor applications is foreseen for the Future Launchers Preparatory Programme (FLPP). TNO has performed different SHM measurements with FBGs including on the VEGA interstage [1, 2] in 2006. Within the current project, a multi-parameter FBG sensor array demonstrator system for temperature and strain measurements is designed, fabricated and tested under ambient as well as Thermal Vacuum (TV) conditions in a TV chamber of the European Space Agency (ESA), ESTEC site. The aim is the development of a multi-parameters measuring system based on FBG technology for space applications. During the TV tests of a Space Craft (S/C) or its subsystems, thermal measurements, as well as strain measurements are needed by the engineers in order to verify their prediction and to validate their models. Because of the dimensions of the test specimen and the accuracy requested to the measurement, a large number of observation/measuring points are needed. Conventional sensor systems require a complex routing of the cables connecting the sensors to their acquisition unit. This will add extra weight to the construction under test. FBG sensors are potentially light-weight and can easily be multiplexed in an array configuration. The different tasks comply of a demonstrator system design; its component selection, procurement, manufacturing and finally its assembly. The temperature FBG sensor is calibrated in a dedicated laboratory setup down to liquid nitrogen (LN2) temperature at TNO. A temperature-wavelength calibration curve is generated. After a test programme definition a setup in thermal vacuum is realised at ESA premises including a mechanical strain transducer to generate strain via a dedicated feed through in the chamber. Thermocouples are used to log the temperature for comparison to the temperature FBG sensor. Extreme temperature ranges from -150°C and +70°C at a pressure down to 10-4 Pa (10-6 mbar) are covered as well as testing under ambient conditions. In total five thermal cycles during a week test are performed. The FBG temperature sensor test results performed in the ESA/ESTEC TV chamber reveal high reproducibility (within 1 °C) within the test temperature range without any evidence of hysteresis. Differences are detected to the previous calibration curve. Investigation is performed to find the cause of the discrepancy. Differences between the test set-ups are identified. Equipment of the TNO test is checked and excluded to be the cause. Additional experiments are performed. The discrepancy is most likely caused by a 'thermal shock' due to rapid cooling down to LN2 temperature, which results in a wavelength shift. Test data of the FBG strain sensor is analysed. The read-out of the FBG strain sensor varies with the temperature during the test. This can be caused by temperature induced changes in the mechanical setup (fastening of the mechanical parts) or impact of temperature to the mechanical strain transfer to the FBG. Improvements are identified and recommendations given for future activities.

A 1microW 85nV/ radicalHz pseudo open-loop preamplifier with programmable band-pass filter for neural interface system.

We report an energy efficient pseudo open-loop amplifier with programmable band-pass filter developed for neural interface systems. The proposed amplifier consumes 400nA at 2.5V power supply. The measured thermal noise level is 85nV/ radicalHz and input-referred noise is 1.69microV(rms) from 0.3Hz to 1 kHz. The amplifier has a noise efficiency factor of 2.43, the lowest in the differential topologies reported up to date to our knowledge. By programming the switched-capacitor frequency and bias current, we could control the bandwidth of the preamplifier from 138 mHz to 2.2 kHz to meet various application requirements. The entire preamplifier including band-pass filters has been realized in a small area of 0.043mm(2) using a 0.25microm CMOS technology.

Infrared (IR) image synthesis for ocean scene has become more and more important nowadays, especially for remote sensing and military application. Although a number of works present ready-to-use simulations, those techniques cover only a few possible ways of water interacting with the environment. And the detail calculation of ocean temperature is rarely considered by previous investigators. With the advance of programmable features of graphic card, many algorithms previously limited to offline processing have become feasible for real-time usage. In this paper, we propose an efficient algorithm for real-time rendering of infrared ocean scene using the newest features of programmable graphics processors (GPU). It differs from previous works in three aspects: adaptive GPU-based ocean surface tessellation, sophisticated balance equation of thermal balance for ocean surface, and GPU-based rendering for infrared ocean scene. Finally some results of infrared image are shown, which are in good accordance with real images.

Evitherm is a web-based thermal resource centre, resulting from a 3-year project partly funded by the EU’s GROWTH programme (2002 05). Evitherm links together the widely distributed centres of excellence (NMIs, research and teaching institutes, consultants, etc.) and others concerned with thermal measurements and technology to provide a focal point for information exchange and knowledge transfer between all these organizations and industry. To facilitate the quick and easy flow of thermal knowledge to users of thermal technologies, evitherm has a website (www.evitherm.org) through which it disseminates information and by which it also provides access to resources such as training, property data, measurements and experts. Among the resources available from the website are (1) thermal property data—offering access to some of the world’s leading databases; (2) expertise— evitherm has a database of consultants, an Advice line, a public Forum and a unique Consultancy Brokering Service whereby users are linked to the expert they need to solve their thermal industrial problems; (3) industry resources—thermal information for particular industry sectors; (4) services—information directories on thermal property measurement, training, equipment supply, reference materials, etc.; (5) literature—links to books, papers, standards, etc.; (6) events—conferences, meetings, seminars, organizations and networks, what’s happening. A user only has to register (for free) to gain access to all the information on the evitherm website. Much of the thermal property data can be accessed for free and in a few cases we have negotiated affordable rates for access to some leading databases, such as CINDAS, THERSYST and NELFOOD. This article illustrates the aims and structure of the evitherm Society, how it is directed, and how it serves the thermal community worldwide in its need for quick and easy access to the resources needed to help ensure a well resourced industrial work force and clean and efficient thermal processes.

Management of organisational changes in a case of de-institutionalisation.

Parlalis, Stavros K

2011-01-01

This paper seeks to explore the development of a discharge programme in one learning disability hospital in Scotland. The study aims to concentrate on organisational developmental changes in that institution. The model of the management during the discharge programme was investigated. The aim of the study is to explore how the discharge programme developed, as seen under the lens of organisational change, in order to find out what kind of model of management is more suitable in similar programmes. A case study was employed. Data were collected by means of interviews. The interviews followed a structured format. The sample of the study had to be a purposive sample and the method of snowball sampling was used; finally, 28 interviews were conducted. A grounded approach was adopted for the data analysis. The software program QSR "NUD*IST" (version "N6") was used as a technical tool, in order to facilitate the data analysis. The findings of this study show that various management models were adopted in the four phases of the discharge programme. These different models represent a "quest" by the institution's management regarding the most appropriate model for managing the discharge programme. This study shows that this goes on continuously in organisations under transition until they settle down to a more permanent state. It was concluded that management models, which are composed of characteristics from the organic theory of organisational management, could apply in discharge programmes. The data gathered enabled the researcher to arrive at a model of management which is suitable for managing organisational changes in discharge programmes, the named "stakeholder management model".

Djomba, Janet Klara; Zaletel-Kragelj, Lijana

2016-12-01

Research on social networks in public health focuses on how social structures and relationships influence health and health-related behaviour. While the sociocentric approach is used to study complete social networks, the egocentric approach is gaining popularity because of its focus on individuals, groups and communities. One of the participants of the healthy lifestyle health education workshop 'I'm moving', included in the study of social support for exercise was randomly selected. The participant was denoted as the ego and members of her/his social network as the alteri. Data were collected by personal interviews using a self-made questionnaire. Numerical methods and computer programmes for the analysis of social networks were used for the demonstration of analysis. The size, composition and structure of the egocentric social network were obtained by a numerical analysis. The analysis of composition included homophily and homogeneity. Moreover, the analysis of the structure included the degree of the egocentric network, the strength of the ego-alter ties and the average strength of ties. Visualisation of the network was performed by three freely available computer programmes, namely: Egonet.QF, E-net and Pajek. The computer programmes were described and compared by their usefulness. Both numerical analysis and visualisation have their benefits. The decision what approach to use is depending on the purpose of the social network analysis. While the numerical analysis can be used in large-scale population-based studies, visualisation of personal networks can help health professionals at creating, performing and evaluation of preventive programmes, especially if focused on behaviour change.

Introduction Children with cerebral palsy (CP) and other neurodevelopmental disabilities often receive a home programme of exercises to assist in reaching their therapy goals. Adherence to exercise programmes is necessary to attain the level of practice required to achieve goals; however, adherence can be difficult to accomplish. In this paper, we describe the protocol for a randomised controlled trial to evaluate the effectiveness of delivering a home exercise programme to school-age children with disabilities using Physitrack, an online exercise prescription tool with a website or app interface. Methods and analysis Participants aged 6–17 years, with CP or other neurodevelopmental disabilities, receiving community physiotherapy services in Western Australia, will be recruited. Participants will be stratified by age and functional mobility and randomised to either the intervention group, who will complete an 8-week home exercise programme using Physitrack, or the control group, who will complete an 8-week exercise programme without Physitrack. Researcher blinding to group allocation, and participant blinding to outcome, will be maintained. The primary outcome measures are adherence to the home exercise programme with weekly collection of home exercise logs; achievement of individualised goals by phone interview before and after intervention; and correctness of exercise performance by collection and analysis of videos of participants performing home exercises. Secondary outcome measures include enjoyment of physical activity, confidence to complete exercise programme, preferred method of delivery of programme and usability of Physitrack. A sample size of 58 participants will be necessary to see an effect on home programme adherence. Data will be analysed using the intention-to-treat principle. Ethics and dissemination Ethical approval was obtained from Curtin University Human Research Ethics Committee in July 2016 (10391). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at scientific conferences. Trial registration number ACTRN12616000743460; Pre-results. PMID:29362255

Methods: Thermogravimetry (TGA), derivative thermogravimetry (DTG) and differential thermal analysis (DTA) were used through the work to achieve the thermal analysis study of some antihypertensive drugs, telmisartan and cilazapril. Results: The results led to thermal stability data and also to the interpretation concerning the thermal decomposition. Thermogravimetry data allowed determination of the kinetic parameters such as, activation energy and frequency factor. Conclusion: The simplicity, speed and low operational costs of thermal analysis justify its application in the quality control of pharmaceutical compounds for medications. PMID:24754013

How to calculate the annual costs of NGO-implemented programmes to support orphans and vulnerable children: a six-step approach

PubMed Central

2011-01-01

Background Information on the costs of implementing programmes designed to provide support of orphans and vulnerable children (OVC) in sub-Saharan Africa and elsewhere is increasingly being requested by donors for programme evaluation purposes. To date, little information exists to document the costs and structure of costs of OVC programmes as actually implemented "on the ground" by local non-governmental organizations (NGOs). This analysis provides a practical, six-step approach that NGOs can incorporate into routine operations to evaluate their costs of implementing their OVC programmes annually. This approach is applied to the Community-Based Care for Orphans and Vulnerable Children (CBCO) Program implemented by BIDII (a Kenyan NGO) in Eastern Province of Kenya. Methods and results The costing methodology involves the following six steps: accessing and organizing the NGO's annual financial report into logical sub-categories; reorganizing the sub-categories into input cost categories to create a financial cost profile; estimating the annual equivalent payment for programme equipment; documenting donations to the NGO for programme implementation; including a portion of NGO organizational costs not attributed to specific programmes; and including the results of Steps 3-5 into an expanded cost profile. Detailed results are provided for the CBCO programme. Conclusions This paper shows through a concrete example how NGOs implementing OVC programmes (and other public health programmes) can organize themselves for data collection and documentation prospectively during the implementation of their OVC programmes so that costing analyses become routine practice to inform programme implementation rather than a painful and flawed retrospective activity. Such information is required if the costs and outcomes achieved by OVC programmes will ever be clearly documented and compared across OVC programmes and other types of programmes (prevention, treatment, etc.).

The aim of this study was to understand experiences of participation in a supported self-management programme for chronic obstructive pulmonary disease (COPD). There is a wealth of clinical trials examining the outcomes of self-management interventions for individuals with COPD, but current understanding regarding patients' perspectives of such complex interventions is limited. Further insight may help to tailor self-management interventions and maximise patient engagement. Semi-structured interviews were conducted with individuals participating in a self-management programme, SPACE for COPD. Interviews took place at 6 weeks and 6 months following the programme. Data were analysed at each time point using inductive thematic analysis, and subsequently re-examined together. 40 interviews were undertaken and four themes emerged from the analysis: perceptions of the programme; lifestyle changes; social support; and disrupting factors and barriers to maintaining routines. SPACE for COPD was acceptable to participants in this study. The importance of education and social support was emphasised at both time points studied, but there were challenges such as comorbidities, ill health of family members and limited maintenance of exercise behaviours over the longer term. Further consideration of the role of carers and partners may help to improve adherence to self-management programmes once healthcare professional support has stopped.

Thermal Analysis of Thermal Protection System of Test Launch Vehicle

NASA Astrophysics Data System (ADS)

Kim, Jongmin

2017-10-01

In this paper, a thermal analysis of the thermal protection system (TPS) of test launch vehicle (TLV) is explained. TLV is heated during the flight due to engine exhaust plume gas by thermal radiation and a TPS is needed to protect the vehicle from the heating. The thermal analysis of the TPS is conducted to predict the heat flux from plume gas and temperature of the TPS during the flight. To simplify the thermal analysis, plume gas radiation and radiative properties are assumed to be surface radiation and constants, respectively. Thermal conductivity, emissivity and absorptivity of the TPS material are measured. Proper plume conditions are determined from the preliminary analysis and then the heat flux and temperature of the TPS are calculated.

Since its introduction in 2009, the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has been implemented in 617 laboratories in 47 countries. We completed a systematic review of the published literature on SLMTA. The review consists of two companion papers; this article examines quantitative evidence presented in the publications along with a meta-analysis of selected results. We identified 28 published articles with data from SLMTA implementation. The SLMTA programme was evaluated through audits based on a standard checklist, which is divided into 12 sections corresponding to the 12 Quality System Essentials (QSEs). Several basic service delivery indicators reported by programmes were also examined. Results for various components of the programme were reviewed and summarised; a meta-analysis of QSE results grouped by the three stages of the quality cycle was conducted for 126 laboratories in 12 countries. Global programme data show improved quality in SLMTA laboratories in every country, with average improvements on audit scores of 25 percentage points. Meta-analysis identified Improvement Management as the weakest stage, with internal audit (8%) and occurrence management (16%) showing the lowest scores. Studies documented 19% - 95% reductions in turn-around times, 69% - 93% reductions in specimen rejection rates, 76% - 81% increases in clinician satisfaction rates, 67% - 85% improvements in external quality assessment results, 50% - 66% decreases in nonconformities and 67% increases in staff punctuality. The wide array of results reported provides a comprehensive picture of the SLMTA programme overall, suggesting a substantive impact on provision of quality laboratory services and patient care. These comprehensive results establish a solid data-driven foundation for program improvement and further expansion.

Men's Sheds are community spaces where socialisation occurs alongside participation in meaningful activities. Shed activities and socialisation make them useful for supporting transition to adulthood of 'at-risk' young people through meaningful occupations. Many sheds have implemented intergenerational mentoring programmes. However, many programmes are established on an ad-hoc basis without specific attention to factors that may support effective and sustainable outcomes. We aimed to inform future programmes by exploring different programmes to provide insight into the purpose, design and programme characteristics that are perceived as beneficial for young males. Four Sydney-based sheds providing intergenerational mentoring programmes were selected. We interviewed shed coordinators, mentors and mentees to explore their perceptions of programme characteristics that supported mentees' transition to adulthood. Thematic analysis techniques were used to first analyse and understand the unique context of each programme and these were then merged and integrated to identify the most helpful aspects of these mentoring programmes. Mentor attitude towards the mentees, freedom to make independent choices and the nature and perceived usefulness of the project were considered the most significant characteristics of these programmes. This was the first known examination of the different characteristics of Men's Sheds intergenerational mentoring programmes. On the basis of our findings, we have made recommendations to help guide the planning and implementation of future programmes. While our findings largely support previous research on mentoring programmes, findings from this study suggest that 'expert skills' may not be as important as mentor attitude to working with the mentees. © 2016 Occupational Therapy Australia.

Outcomes for engineering students delivering a STEM education and outreach programme

Fitzallen, Noleine; Brown, Natalie Ruth

2017-11-01

University science outreach programmes are used to encourage more school students to select science, technology, engineering, and mathematics (STEM) subjects in further education and pursue science-related careers. The benefits of science outreach programmes are often espoused from the perspective of programme participants. Little attention, however, is given to what university students delivering the programmes gain from the experience. This paper seeks to illustrate the benefits of engineering students delivering STEM outreach programmes in schools. It reports on a qualitative case study of the experiences of two STEM Education and Outreach team members from a regional university in Australia. Content analysis of interview data highlighted not only the participants' motivations and perceived benefits of being involved in the STEM programme but also revealed the skills and attributes honed throughout the experience. Involvement in the STEM outreach programme resulted in the development of social and personal responsibility generic graduate attribute skills, evidenced through their motivations to be involved, the demonstration of understanding of teaching and learning, and application of science communication skills. This study demonstrates that designing and delivering STEM outreach programmes assists in the development of skills that will be beneficial when pursuing careers in engineering in the future.

An integrative review of graduate transition programmes: Developmental considerations for nursing management.

Graduate transition programmes have been developed to recruit new nursing staff and facilitate an effective transition from nursing student to Registered Nurse within the clinical environment. Therefore the aim of this paper was to explore the various elements included in nursing graduate transition programmes. An integrative review was undertaken incorporating a strict inclusion criterion, critical appraisal, and thematic analysis of 30 studies. There are numerous transition programmes available yet there remains a lack of transparency regarding their aims/objectives, course content, support timeframe and the type of support provided. This inconsistency has resulted in a lack of clarity regarding efficacy or superiority of any one programme over another. Innovative multifaceted programs may assist in supporting the graduate registered nurse to transition effectively into the clinical environment. Providing these support programmes may allow nurse managers to recruit new graduates and therefore decrease the staff budget expenditure. No graduate programme was shown to be superior to others yet graduate programmes appear to positively influence the experience of the graduate and increase staff recruitment. Comparative research is needed to ascertain the integral components of these programmes. Copyright © 2017. Published by Elsevier Ltd.

Implementing large-scale programmes to optimise the health workforce in low- and middle-income settings: a multicountry case study synthesis.

To identify factors affecting the implementation of large-scale programmes to optimise the health workforce in low- and middle-income countries. We conducted a multicountry case study synthesis. Eligible programmes were identified through consultation with experts and using Internet searches. Programmes were selected purposively to match the inclusion criteria. Programme documents were gathered via Google Scholar and PubMed and from key informants. The SURE Framework - a comprehensive list of factors that may influence the implementation of health system interventions - was used to organise the data. Thematic analysis was used to identify the key issues that emerged from the case studies. Programmes from Brazil, Ethiopia, India, Iran, Malawi, Venezuela and Zimbabwe were selected. Key system-level factors affecting the implementation of the programmes were related to health worker training and continuing education, management and programme support structures, the organisation and delivery of services, community participation, and the sociopolitical environment. Existing weaknesses in health systems may undermine the implementation of large-scale programmes to optimise the health workforce. Changes in the roles and responsibilities of cadres may also, in turn, impact the health system throughout. © 2014 John Wiley & Sons Ltd.

The SEDIBUD (Sediment Budgets in Cold Environments) Programme: Current activities and future key tasks

Beylich, A. A.; Lamoureux, S. F.; Decaulne, A.

2012-04-01

Projected climate change in cold regions is expected to alter melt season duration and intensity, along with the number of extreme rainfall events, total annual precipitation and the balance between snowfall and rainfall. Similarly, changes to the thermal balance are expected to reduce the extent of permafrost and seasonal ground frost and increase active layer depths. These effects will undoubtedly change surface environments in cold regions and alter the fluxes of sediments, nutrients and solutes, but the absence of quantitative data and coordinated process monitoring and analysis to understand the sensitivity of the Earth surface environment is acute in cold climate environments. The International Association of Geomorphologists (I.A.G./A.I.G.)SEDIBUD (Sediment Budgets in Cold Environments) Programme was formed in 2005 to address this existing key knowledge gap. SEDIBUD currently has about 400 members worldwide and the Steering Committee of this international programme is composed of ten scientists from eight different countries: Achim A. Beylich (Chair) (Norway), Armelle Decaulne (Secretary) (France), John C. Dixon (USA), Scott F. Lamoureux (Vice-Chair) (Canada), John F. Orwin (Canada), Jan-Christoph Otto (Austria), Irina Overeem (USA), Thorsteinn Saemundsson (Iceland), Jeff Warburton (UK), Zbigniew Zwolinski (Poland). The central research question of this global group of scientists is to: Assess and model the contemporary sedimentary fluxes in cold climates, with emphasis on both particulate and dissolved components. Initially formed as European Science Foundation (ESF) Network SEDIFLUX (2004-2006), SEDIBUD has further expanded to a global group of researchers with field research sites located in polar and alpine regions in the northern and southern hemisphere. Research carried out at each of the close to 50 defined SEDIBUD key test sites varies by programme, logistics and available resources, but typically represent interdisciplinary collaborations of geomorphologists, hydrologists, ecologists, permafrost scientists and glaciologists. SEDIBUD has developed manuals and protocols (SEDIFLUX Manual, available online, see below) with a key set of primary surface process monitoring and research data requirements to incorporate results from these diverse projects and allow coordinated quantitative analysis across the programme. Defined SEDIBUD key test sites provide data on annual climate conditions, total discharge and particulate and dissolved fluxes as well as information on other relevant surface processes. A number of selected key test sites is providing high-resolution data on climate conditions, runoff and sedimentary fluxes, which in addition to the annual data contribute to the SEDIBUD metadata database which is currently developed. Comparable datasets from different SEDIBUD key test sites are integrated and analysed to address key research questions as defined in the SEDIBUD Objective (available online, see below). Defined SEDIBUD key tasks for the coming years include (i) The continued generation and compilation of comparable longer-term datasets on contemporary sedimentary fluxes and sediment yields from SEDIBUD key test sites worldwide, (ii) The continued extension of the SEDIBUD metadata database with these datasets, (iii) The testing of defined SEDIBUD hypotheses (available online, see below) by using the datasets continuously compiled in the SEDIBUD metadata database.

Prevocational doctors aspiring to surgical careers are commonly recruited as anatomy demonstrators for undergraduate and graduate medical programmes. Entry into Surgical Education and Training (SET) is highly competitive and a unique opportunity exists to align anatomy demonstrator programmes with the selection criteria and core competencies of SET programmes. This study used a qualitative approach to (i) determine what criteria applicants for SET are assessed on and (ii) identify criteria that could be aligned with and enhanced by an anatomy demonstrator programme. The selection guidelines of all nine surgical specialties for the 2017 intake of SET trainees were analysed using qualitative content analysis methodology. The Royal Australasian College of Surgeons adopted a holistic approach to trainee selection that assessed both discipline-specific and discipline-independent skills. Qualitative content analysis identified eight categories of key selection criteria: medical expertise, scholarly activity, professional identity, interpersonal skills, integrity, self-management, insight and self-awareness and community involvement. The structured curriculum vitae was heavily weighted towards discipline-specific skills, such as medical expertise and scholarly activity. Insufficient information was available to determine the weighting of selection criteria assessed by the structured referee reports or interviews. Anatomy demonstrator programmes provide prevocational doctors with unique opportunities to develop surgical skills and competencies in a non-clinical setting. Constructively aligned anatomy demonstrator programmes may be particularly beneficial for prevocational doctors seeking to improve their anatomical knowledge, teaching skills or scholarly activity. © 2017 Royal Australasian College of Surgeons.

An analysis undertaken jointly in 2009 by the UN World Food Programme, The Partnership for Child Development and the World Bank was published as Rethinking School Feeding to provide guidance on how to develop and implement effective school feeding programmes as a productive safety net and as part of the efforts to achieve Education for All. The present paper reflects on how understanding of school feeding has changed since that analysis. Data on school feeding programme outcomes were collected through a literature review. Regression models were used to analyse relationships between school feeding costs (from data that were collected), the per capita costs of primary education and Gross Domestic Product per capita. Data on the transition to national ownership, supply chains and country examples were collected through country case studies. School feeding programmes increase school attendance, cognition and educational achievement, as well as provide a transfer of resources to households with possible benefits to local agricultural production and local market development. Low-income countries exhibit large variations in school feeding costs, with concomitant opportunities for cost containment. Countries are increasingly looking to transition from externally supported projects to national programmes. School feeding is now clearly evident as a major social programme in most countries with a global turnover in excess of $US 100 billion. This argues for a continuing focus on the evidence base with a view to helping countries ensure that their programmes are as cost-effective as possible. Clear policy advice has never been more important.

Implementing family physician programme in rural Iran: exploring the role of an existing primary health care network.

2013-10-01

The primary health care (PHC) network contributed considerably to improving health outcomes in rural Iran. However, the health system suffers from inadequate responses to ever-increasing demands. In 2005, a reform comprised of a family physician (FP) programme and universal health insurance was implemented in all rural areas and cities with a population of <20 000. We explored the role of the pre-existing PHC network on the implementation of FP programme in rural Iran. We conducted a qualitative study involving 71 semi-structured interviews at national, provincial and local levels, and three focus group discussions at local level, plus a purposeful content analysis of documents of various types. We used a mixed inductive/deductive framework approach for data analysis. We identified seven main aspects related to the existing primary health network, which contributed to the implementation of FP programme: 'a respected and functioning PHC network', 'accessibility and geographical coverage', 'efficient hierarchy', 'the only possible host', 'a remedy for chronic challenges in the rural PHC', 'FP as the gatekeeper?' and 'the role of the private sector'. The existence of a functioning PHC was pivotal in driving policy makers' decision to implement FP programme. Implementing a new policy depends on its hosting context. In regards to FP programme and rural insurance in Iran, the existing PHC network proved to be a fundamental asset in facilitating the implementation of FP programme in rural areas.

A comprehensive review of the SLMTA literature part 1: Content analysis and future priorities

Background Since its introduction in 2009, the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has been implemented widely throughout Africa, as well as in the Caribbean, Central and South America, and Southeast Asia. Objective We compiled results from local, national and global studies to provide a broad view of the programme and identify directions for the future. The review consists of two companion papers; this paper focuses on content analysis, examining various thematic components of the SLMTA programme and future priorities. Methods A systematic literature search identified 28 published articles about implementing the SLMTA programme. Results for various components of the SLMTA programme were reviewed and summarised. Results Local and national studies provide substantial information on previous experiences with quality management systems; variations on SLMTA implementation; building human resource capacity for trainers, mentors and auditors; the benefits and effectiveness of various types of mentorship; the importance of management buy-in to ensure country ownership; the need to instill a culture of quality in the laboratory; success factors and challenges; and future directions for the programme. Conclusions Local, national and global results suggest that the SLMTA programme has been overwhelmingly successful in transforming laboratory quality management. There is an urgent need to move forward in four strategic directions: progression (continued improvement in SLMTA laboratories), saturation (additional laboratories within countries that have implemented SLMTA), expansion (implementation in additional countries), and extension (adapting SLMTA for implementation beyond the laboratory), to lead to transformation of overall health systems and patient care.

2016-11-01

This paper describes an engineering outreach programme designed to increase the interest of under-represented youth in engineering and to disseminate pre-engineering design challenge materials to K-12 educators and volunteers. Given university students' critical role as facilitators of the outreach programme, researchers conducted a two-year design experiment to examine the programme's effectiveness at preparing university students to lead pre-engineering activities. Pre- and post-surveys incorporated items from the Student Engagement sub-scale of the Teacher Sense of Efficacy Scale. Surveys were analysed using paired-samples t-test. Interview and open-ended survey data were analysed using discourse analysis and the constant comparative method. As a result of participation in the programme, university students reported a gain in efficacy to lead pre-engineering activities. The paper discusses programme features that supported efficacy gains and concludes with a set of design principles for developing learning environments that effectively prepare university students to facilitate pre-engineering outreach programmes.

Programme costing of a physical activity programme in primary prevention: should the costs of health asset assessment and participatory programme development count?

PubMed

Wolfenstetter, Silke B; Schweikert, Bernd; John, Jürgen

2012-01-01

This analysis aims to discuss the implications of the "health asset concept", introduced by the WHO, and the "investment for health model" requiring a "participatory approach" of cooperative programme development applied on a physical activity programme for socially disadvantaged women and to demonstrate the related costing issues as well as the relevant decision context. The costs of programme implementation amounted to €48,700. Adding the costs for developing the programme design of €48,800 results in total costs of €97,500; adding on top of that the costs of asset assessment running to €35,600 would total €133,100. These four different cost figures match four different types of potentially relevant decisions contexts. Depending on the decision context the total costs, and hence the incremental cost-effectiveness ratio of a health promotion intervention, could differ considerably. Therefore, a detailed cost assessment and the identification of the decision context are of crucial importance.

Newborn screening (NBS) for cystic fibrosis (CF) is a well-established public health strategy with international standards. The aim of this study was to provide an update on NBS for CF in Europe and assess performance against the standards. Questionnaires were sent to key workers in each European country. In 2016, there were 17 national programmes, 4 countries with regional programmes and 25 countries not screening in Europe. All national programmes employed different protocols, with IRT-DNA the most common strategy. Five countries were not using DNA analysis. In addition, the processing and structure of programmes varied considerably. Most programmes were achieving the ECFS standards with respect to timeliness, but were less successful with respect to sensitivity and specificity. There has been a steady increase in national CF NBS programmes across Europe with variable strategies and outcomes that reflect the different approaches.

Hardening and embrittlement of RPV caused by neutron irradiation and thermal ageing are main reasons for mechanical properties degradation during the operation of an NPP. The thermal ageing-induced degradation of RPV steels becomes more significant with extended operational lives of NPPs. Consequently, the evaluation of thermal ageing effects is important for the structural integrity assessments required for the lifetime extension of NPPs. As a part of NRG's research programme on Structural Materials for safe-LTO of Light Water Reactor (LWR) RPVs, WWER-440 surveillance specimens, which have been thermal aged for 27 years (∼200,000 h) at 290 °C in a surveillance channel of Armenian-NPP, are investigated. Results from the mechanical and microstructural examination of these thermal aged specimens are presented in this article. The results indicate the absence of significant long term thermal ageing effect of 15Cr2MoV-A steel. No age hardening was detected in aged tensile specimens compared with the as-received condition. There is no difference between the impact properties of as-received and thermal aged weld metals. The upper shelf energy of the aged steel remains the same as for the as-received material at a rather high level of about 120 J. The T41 value did not change and was found to be about 10 °C. The microstructure of thermal aged weld, consisting carbides, carbonitrides and manganese-silicon inclusions, did not change significantly compared to as-received state. Grain-boundary segregation of phosphorus in long term aged weld is not significant either which has been confirmed by the absence of intergranular fracture increase in the weld. Negligible hardening and embrittlement observed after such long term thermal ageing is attributed to the optimum chemical composition of 15Cr2MoV-A for high thermal stability.

The results of a research project (EU AIR Research Programme CT94-1025) aimed to introduce control of migration into good manufacturing practice and into enforcement work are reported. Representative polymer classes were defined on the basis of chemical structure, technological function, migration behaviour and market share. These classes were characterized by analytical methods. Analytical techniques were investigated for identification of potential migrants. High-temperature gas chromatography was shown to be a powerful method and 1H-magnetic resonance provided a convenient fingerprint of plastic materials. Volatile compounds were characterized by headspace techniques, where it was shown to be essential to differentiate volatile compounds desorbed from those generated during the thermal desorption itself. For metal trace analysis, microwave mineralization followed by atomic absorption was employed. These different techniques were introduced into a systematic testing scheme that is envisaged as being suitable both for industrial control and for enforcement laboratories. Guidelines will be proposed in the second part of this paper.

Eco-Environmental Factors in Green Roof Application in Indian Cities

Mukherjee, M.

2014-09-01

Green-roof is the cost-effective environmental mitigation strategy for urban areas [1]. Its application is limited in India primarily due to inadequate understanding about its cost-benefit analysis and technicalities of its maintenance. Increasing awareness about green roof can alter conservative attitude towards its application. So, this work presents a quantified study on green-roof types, cost and environmental benefits while considering different geo-urban climate scenarios for cities of Kolkata, Mumbai, Chennai and New Delhi. Cost estimation for extensive and intensive green-roof with reference to commonly used roof in urban India is also worked out. Attributes considered for environmental discussion are energy savings related to thermal heat gain through roof, roof-top storm-water drainage and sound attenuation. The comparative study confirms that further focused study on individual cities would identify city-specific objectives for green-roof application; strategies like awareness, capacity building programmes, incentives, demonstration projects etc. can be worked out accordingly for wider application of green-roof in Indian cities.

In preparation of new Electronic Power Conditioners (EPC's) for Travelling Wave Tub Amplifiers (TWTA's) on telecom satellites a study for the development of new high voltage insulation technology is performed. The initiative is mandatory to allow compact designs and to enable higher operating voltages. In a first task a market analysis was performed, comparing different materials with respect to their properties and processes. A hierarchy of selection criteria was established and finally five material candidates (4 Epoxy resins and 1 Polyurethane resin) were selected to be further investigated in the test program. Samples for the test program were designed to represent core elements of an EPC, the high voltage transformer and Printed Circuit Boards of the high voltage section. All five materials were assessed in the practical work flow of the potting process and electrical, mechanical, thermal and lifetime testing was performed. Although the lifetime tests results were overlayed by a larges scatter, finally two candidates have been identified for use in a subsequent qualification program. This activity forms part of element 5 of the ESA ARTES Programme.

The aim of this study was to investigate understandings and strategies of empowerment in Learning and Mastery Centres, in a course in lifestyle change for morbidly obese patients. A field study was conducted with nonparticipant observation, and data analysis was inspired by foucauldian discourse analysis. The analysis revealed powerful discourses underlying the course, and the analysis showed how different discourses were set at play within the teaching strategies in the course. The course leaders balanced powerful aspects that involved directing the participants towards strategies promoting their autonomy. The analysis revealed how strategies to reduce the impression of direction and conduct are powerful actions. From a foucauldian perspective of power, this analysis demonstrates how power is everywhere as a productive force. When creating programmes to empower patients to help them deal with their health, it seems vital that health professionals examine power. By accepting the presence of power, professionals can examine the truth motivation underlying an empowerment programme. © 2010 The Authors.

Abstract RAND Europe evaluated the National Institute for Health Research (NIHR) Leadership Programme in an effort to help the English Department of Health consider the extent to which the programme has helped to foster NIHR's aims, extract lessons for the future, and develop plans for the next phase of the leadership programme. Successful delivery of high-quality health research requires not only an effective research base, but also a system of leadership supporting it. However, research leaders are not often given the opportunity, nor do they have the time, to attend formal leadership or management training programmes. This is unfortunate because research has shown that leadership training can have a hugely beneficial effect on an organisation. Therefore, the evaluation has a particular interest in understanding the role of the programme as a science policy intervention and will use its expertise in science policy analysis to consider this element alongside other, more traditional, measures of evaluation.

2011-01-01

A high-fidelity thermal model of the Mars Reconnaissance Orbiter was developed for use in an autonomous aerobraking simulation study. Response surface equations were derived from the high-fidelity thermal model and integrated into the autonomous aerobraking simulation software. The high-fidelity thermal model was developed using the Thermal Desktop software and used in all phases of the analysis. The use of Thermal Desktop exclusively, represented a change from previously developed aerobraking thermal analysis methodologies. Comparisons were made between the Thermal Desktop solutions and those developed for the previous aerobraking thermal analyses performed on the Mars Reconnaissance Orbiter during aerobraking operations. A variable sensitivity screening study was performed to reduce the number of variables carried in the response surface equations. Thermal analysis and response surface equation development were performed for autonomous aerobraking missions at Mars and Venus.

Some injury prevention programmes aim to reduce the risk of ACL rupture. Although the most common athletic task leading to ACL rupture is cutting, there is currently no consensus on how injury prevention programmes influence cutting task biomechanics. To systematically review and synthesise the scientific literature regarding the influence of injury prevention programme exercises on cutting task biomechanics. The three largest databases (Medline, EMBASE and CINAHL) were searched for studies that investigated the effect of injury prevention programmes on cutting task biomechanics. When possible meta-analyses were performed. Seven studies met the inclusion criteria. Across all studies, a total of 100 participants received exercises that are part of ACL injury prevention programmes and 76 participants served in control groups. Most studies evaluated variables associated with the quadriceps dominance theory. The meta-analysis revealed decreased lateral hamstrings electromyography activity (p ≤ 0.05) while single studies revealed decreased quadriceps and increased medial hamstrings activity and decreased peak knee flexion moment. Findings from single studies reported that ACL injury prevention exercises reduce neuromuscular deficits (knee valgus moment, lateral trunk leaning) associated with the ligament and trunk dominance theories, respectively. The programmes we analysed appear most effective when they emphasise individualised biomechanical technique correction and target postpubertal women. The exercises used in injury prevention programmes have the potential to improve cutting task biomechanics by ameliorating neuromuscular deficits linked to ACL rupture, especially when they emphasise individualised biomechanical technique correction and target postpubertal female athletes.

Health system changes under pay-for-performance: the effects of Rwanda's national programme on facility inputs.

Ngo, Diana K L; Sherry, Tisamarie B; Bauhoff, Sebastian

2017-02-01

Pay-for-performance (P4P) programmes have been introduced in numerous developing countries with the goal of increasing the provision and quality of health services through financial incentives. Despite the popularity of P4P, there is limited evidence on how providers achieve performance gains and how P4P affects health system quality by changing structural inputs. We explore these two questions in the context of Rwanda's 2006 national P4P programme by examining the programme's impact on structural quality measures drawn from international and national guidelines. Given the programme's previously documented success at increasing institutional delivery rates, we focus on a set of delivery-specific and more general structural inputs. Using the programme's quasi-randomized roll-out, we apply multivariate regression analysis to short-run facility data from the 2007 Service Provision Assessment. We find positive programme effects on the presence of maternity-related staff, the presence of covered waiting areas and a management indicator and a negative programme effect on delivery statistics monitoring. We find no effects on a set of other delivery-specific physical resources, delivery-specific human resources, delivery-specific operations, general physical resources and general human resources. Using mediation analysis, we find that the positive input differences explain a small and insignificant fraction of P4P's impact on institutional delivery rates. The results suggest that P4P increases provider availability and facility operations but is only weakly linked with short-run structural health system improvements overall. © The Author 2016.

Choosing options for ultrasound screening in pregnancy and comparing cost effectiveness: a decision analysis approach.

1998-09-01

To compare the cost effectiveness of different programmes of routine antenatal ultrasound screening to detect four key fetal anomalies: serious cardiac anomalies, spina bifida, Down's syndrome and lethal anomalies, using existing evidence. Decision analysis was used based on the best data currently available, including expert opinion from the Royal College of Obstetricians and Gynaecologists, Working Party and secondary data from the literature, to predict the likely outcomes in terms of malformations detected by each screening programme. Results applicable in clinics, hospitals or GP practices delivering antenatal screening. The number of cases with a 'target' malformation correctly detected antenatally. There was substantial overlap between the cost ranges of each screening programme demonstrating considerable uncertainty about the relative economic efficiency of alternative programmes for ultrasound screening. The cheapest, but not the most effective, screening programme consisted of one second trimester ultrasound scan. The cost per target anomaly detected (cost effectiveness) for this programme was in the range 5,000 pound silver-109,000, pound silver but in any 1000 women it will also fail to detect between 3.6 and 4.7 target anomalies. The range of uncertainty in the costs did not allow selection of any one programme as a clear choice for NHS purchasers. The results suggested that the overall allocation of resources for routine ultrasound screening in the UK is not currently economically efficient, but that certain scenarios for ultrasound screening are potentially within the range of cost effectiveness reached by other, possibly competing, screening programmes. The model highlighted the weakness of available evidence and demonstrated the need for more information both about current practice and costs.

Few studies have examined the impact of community-based smoke alarm (SA) distribution programmes on the occurrence of house fire-related deaths and injuries (HF-D/I). To determine whether the rate of HF-D/I differed for programme houses that had a SA installed through a community-based programme called Operation Installation, versus non-programme houses in the same census tracts that had not received such a SA. Teams of volunteers and firefighters canvassed houses in 36 high-risk target census tracts in Dallas, TX, between April 2001 and April 2011, and installed lithium-powered SAs in houses where residents were present and gave permission. We then followed incidence of HF-D/I among residents of the 8134 programme houses versus the 24 346 non-programme houses. After a mean of 5.2 years of follow-up, the unadjusted HF-D/I rate was 68% lower among residents of programme houses versus non-programme houses (3.1 vs 9.6 per 100 000 population, respectively; rate ratio, 0.32; 95% CI 0.10 to 0.84). Multivariate analysis including several demographic variables showed that the adjusted HF-D/I rate in programme houses was 63% lower than non-programme houses. The programme was most effective in the first 5 years after SA installation, with declining difference in rates after the 6th year, probably due to SAs becoming non-functional during that time. This collaborative, community-based SA installation programme was effective at preventing deaths and injuries from house fires, but the duration of effectiveness was less than 10 years.

Joint programmes in paediatric cardiothoracic surgery: a survey and descriptive analysis.

2011-12-01

Joint programmes, as opposed to regionalisation of paediatric cardiac care, may improve outcomes while preserving accessibility. We determined the prevalence and nature of joint programmes. We sent an online survey to 125 paediatric cardiac surgeons in the United States in November, 2009 querying the past or present existence of a joint programme, its mission, structure, function, and perceived success. A total of 65 surgeon responses from 65 institutions met the criteria for inclusion. Of the 65 institutions, 22 currently or previously conducted a joint programme. Compared with primary institutions, partner institutions were less often children's hospitals (p = 0.0004), had fewer paediatric beds (p = 0.005), and performed fewer cardiac cases (p = 0.03). Approximately 47% of partner hospitals performed fewer than 50 cases per year. The median distance range between hospitals was 41-60 miles, ranging from 5 to 1000 miles. Approximately 54% of partner hospitals had no surgeon working primarily on-site, and 31% of the programmes conducted joint conferences. Approximately 67% of the programmes limited the complexity of cases at the partner hospital, and 83% of the programmes had formal contracts between hospitals. Of the six programmes whose main mission was to increase referrals to the primary hospital, three were felt to have failed. Of the nine programmes whose mission was to increase regional quality, eight were felt to be successful. Joint programmes in paediatric cardiac surgery are common but are heterogeneous in structure and function. Programmes whose mission is to improve the quality of regional care seem more likely to succeed. Joint programmes may be a practical alternative to regionalisation to achieve better outcomes.

To assess the clinical and cost-effectiveness of parent training programmes for the treatment of children with conduct disorder (CD) up to the age of 18 years. Electronic databases. For the effectiveness review, relevant studies were identified and evaluated. A quantitative synthesis of behavioural outcomes across trials was also undertaken using two approaches: vote counting and meta-analysis. The economic analysis consisted of reviewing previous economic/cost evaluations of parent training/education programmes and the economic information within sponsor's submissions; carrying out a detailed exploration of costs of parent training/education programmes; and a de novo modelling assessment of the cost-effectiveness of parent training/education programmes. The potential budget impact to the health service of implementing such programmes was also considered. Many of the 37 randomised controlled trials that met the review inclusion and exclusion criteria were assessed as being of poor methodological quality. Studies were clinically heterogeneous in terms of the population, type of parent training/education programme and content, setting, delivery, length and child behaviour outcomes used. Both vote counting and meta-analysis revealed a consistent trend across all studies towards short-term effectiveness (up to 4 months) of parent training/education programmes (compared with control) as measured by a change in child behaviour. Pooled estimates showed a statistically significant improvement on the Eyberg Child Behaviour Inventory frequency and intensity scales, the Dyadic Parent-Child Interaction Coding System and the Child Behaviour Checklist. No studies reported a statistically significant result favouring control over parent training/education programmes. There were few statistically significant differences between different parent training/education programmes, although there was a trend towards more intensive interventions (e.g. longer contact hours, additional child involvement) being more effective. The cost of treating CD is high, with costs incurred by many agencies. A recent study suggested that by age 28, costs for individuals with CD were around 10 times higher than for those with no problems, with a mean cost of 70,019 pounds sterling. Criminality incurs the greatest cost, followed by educational provision, foster and residential care and state benefits. Only a small proportion of these costs fall on health services. Using a 'bottom-up' costing approach, the costs per family of providing parent training/education programmes range from 629 pounds sterling to 3839 pounds sterling depending on the type and style of delivery. Using the conservative assumption that there are no cost savings from treatment, a total lifetime quality of life gain of 0.1 would give a cost per quality-adjusted life-year of between 38,393 pounds sterling and 6288 pounds sterling depending on the type of programme delivery and setting. Parent training/education programmes appear to be an effective and potentially cost-effective therapy for children with CD. However, the relative effectiveness and cost-effectiveness of different models (such as therapy intensity and setting) require further investigation. Further research is required on the impact of parent training/education programmes on the quality of life of children with CD and their parents/carers, as well as on longer term child outcomes.

Quality Assurance in Environmental Technology Verification (ETV): Analysis and Impact on the EU ETV Pilot Programme Performance

2018-03-01

Many innovative environmental technologies never reach the market because they are new and cannot demonstrate a successful track record of previous applications. This fact is a serious obstacle on their way to the market. Lack of credible data on the performance of a technology causes mistrust of investors in innovations, especially from public sector, who seek effective solutions however without compromising the technical and financial risks associated with their implementation. Environmental technology verification (ETV) offers a credible, robust and transparent process that results in a third party confirmation of the claims made by the providers about the performance of the novel environmental technologies. Verifications of performance are supported by high quality, independent test data. In that way ETV as a tool helps establish vendor credibility and buyer confidence. Several countries across the world have implemented ETV in the form of national or regional programmes. ETV in the European Union was implemented as a voluntary scheme if a form of a pilot programme. The European Commission launched the Environmental Technology Pilot Programme of the European Union (EU ETV) in 2011. The paper describes the European model of ETV set up and put to operation under the Pilot Programme of Environmental Technologies Verification of the European Union. The goal, objectives, technological scope, involved entities are presented. An attempt has been made to summarise the results of the EU ETV scheme performance available for the period of 2012 when the programme has become fully operational until the first half of 2016. The study was aimed at analysing the overall organisation and efficiency of the EU ETV Pilot Programme. The study was based on the analysis of the documents the operation of the EU ETV system. For this purpose, a relevant statistical analysis of the data on the performance of the EU ETV system provided by the European Commission was carried out.

Systematic reviews of bladder training and voiding programmes in adults: a synopsis of findings from data analysis and outcomes using metastudy techniques.

This paper reports a comparison of the data analysis and outcomes from four Cochrane systematic reviews on bladder training and voiding programmes for the management of urinary incontinence using metastudy descriptive techniques to inform clinical practice, generate new ideas and identify future research directions. Bladder training is used for cognitively and physically able adults to regain continence by increasing the time interval between voids. Prompted voiding, habit retraining and timed voiding, collectively known as voiding programmes, are generally used for people with cognitive and physical impairments in institutional settings. Bladder training and voiding programmes feature as common clinical practice for the management of urinary incontinence. A synopsis of four Cochrane systematic reviews that included randomized controlled trials on bladder training, prompted voiding, habit retraining and timed voiding was undertaken using metastudy techniques for the synthesis of qualitative research, and has provided a discursive comparison and contrast of the meta-data analysis and outcomes of these reviews. Frequency of incontinence was the most common and constant outcome measure of effectiveness in the reviews. Limited data were available on other health outcomes, change in dependency status, quality of life and cost-effectiveness. The systematic review on bladder training included different types of urinary incontinence, whereas those on voiding programmes did not differentiate the type of incontinence. There is evidence on the effectiveness of bladder training but long-term follow up studies are needed. Evidence on the effectiveness of voiding programmes is limited and not available for many outcomes. Future research needs to consider the theory underpinning interventions for bladder training and voiding programmes for urinary incontinence and should incorporate recognized 'quality' research designs, established outcomes and long-term follow up. It is unclear whether health outcomes for people with comorbidities, cognitive and physical impairments will improve if extensive diagnostic and assessment investigations are undertaken.

How can systems engineering inform the methods of programme evaluation in health professions education?

We evaluate programmes in health professions education (HPE) to determine their effectiveness and value. Programme evaluation has evolved from use of reductionist frameworks to those addressing the complex interactions between programme factors. Researchers in HPE have recently suggested a 'holistic programme evaluation' aiming to better describe and understand the implications of 'emergent processes and outcomes'. We propose a programme evaluation framework informed by principles and tools from systems engineering. Systems engineers conceptualise complexity and emergent elements in unique ways that may complement and extend contemporary programme evaluations in HPE. We demonstrate how the abstract decomposition space (ADS), an engineering knowledge elicitation tool, provides the foundation for a systems engineering informed programme evaluation designed to capture both planned and emergent programme elements. We translate the ADS tool to use education-oriented language, and describe how evaluators can use it to create a programme-specific ADS through iterative refinement. We provide a conceptualisation of emergent elements and an equation that evaluators can use to identify the emergent elements in their programme. Using our framework, evaluators can analyse programmes not as isolated units with planned processes and planned outcomes, but as unfolding, complex interactive systems that will exhibit emergent processes and emergent outcomes. Subsequent analysis of these emergent elements will inform the evaluator as they seek to optimise and improve the programme. Our proposed systems engineering informed programme evaluation framework provides principles and tools for analysing the implications of planned and emergent elements, as well as their potential interactions. We acknowledge that our framework is preliminary and will require application and constant refinement. We suggest that our framework will also advance our understanding of the construct of 'emergence' in HPE research. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

A training programme was developed and delivered to a cohort of volunteers who were preparing for a unique role to provide companionship to dying patients in the acute hospital setting. This comprehensive programme aimed to provide an opportunity for participants to fully understand the nature and responsibilities of the role, whilst also allowing sufficient time to assess the qualities and competencies of participants for their ongoing volunteering role. Participants completed reflective diaries throughout the training course to record their ongoing thoughts and feelings. The purpose of this paper is to present a phenomenological analysis of these entries to understand participants' experiences, perceptions and motivations. The wider study was structured into three phases. Phase 1 was the delivery of a 12 week, bespoke training programme; Phase 2 involved a 26 week pilot implementation of the Care of the Dying Volunteer Service and Phase 3 was the research evaluation of the training and implementation which would inform the further development of the training programme. Self-reflection is a common component of End of Life training programmes and volunteers in this study completed a reflective diary after participation in each of the training sessions. A thematic analysis was undertaken to explore and understand the participants' experience, perceptions and motivations in relation to their participation in the training. All 19 volunteers completed the reflective diaries. From a potential 228 diary entries over the 12 week training programme, 178 diary entries were submitted (78 %). The following key themes were identified: Dying Alone and the importance of being present, Personal loss and the reconstruction of meaning, Self-Awareness and Personal growth, Self-preservation and Coping strategies and group unity/cohesion. The participants in this study demonstrated that they were able to use the diaries as an appropriate medium for reflection. Their reflections were also instrumental in the ongoing revision and development of the training programme. Analysis of their entries illustrated that the diaries could provide the opportunity for a reappraisal of their world view and personal philosophy around death and dying. Further research is undoubtedly required, however this paper suggests that self-reflection in this way, supports preparation in honing the appropriate attitudes and qualities required to work in this role.

Leadership and governance of community health worker programmes at scale: a cross case analysis of provincial implementation in South Africa.

National community health worker (CHW) programmes are returning to favour as an integral part of primary health care systems, often on the back of pre-existing community based initiatives. There are significant challenges to the integration and support of such programmes, and they require coordination and stewardship at all levels of the health system. This paper explores the leadership and governance tasks of large-scale CHW programmes at sub-national level, through the case of national reforms to South Africa's community based sector, referred to as the Ward Based Outreach Team (WBOT) strategy. A cross case analysis of leadership and governance roles, drawing on three case studies of adoption and implementation of the WBOTs strategy at provincial level (Western Cape, North West and Gauteng) was conducted. The primary case studies mapped system components and assessed implementation processes and contexts. They involved teams of researchers and over 200 interviews with stakeholders from senior to frontline, document reviews and analyses of routine data. The secondary, cross case analysis specifically focused on the issues and challenges facing, and strategies adopted by provincial and district policy makers and managers, as they engaged with the new national mandate. From this key sub-national leadership and governance roles were formulated. Four key roles are identified and discussed: 1. Negotiating a fit between national mandates and provincial and district histories and strategies of community based services 2. Defining new organisational and accountability relationships between CHWs, local health services, communities and NGOs 3. Revising and developing new aligned and integrated planning, human resource, financing and information systems 4. Leading change by building new collective visions, mobilising political, including budgetary, support and designing implementation strategies. This analysis, from real-life systems, adds to understanding of the processes involved in developing CHW programmes at scale, and specifically the negotiated and multilevel nature of leadership and governance in such programmes, spanning analytic, managerial, technical and political roles.

As the workstation and personal computer become more popular than a centralized mainframe to perform thermal analysis, the methods for space vehicle thermal analysis will change. Already, many thermal analysis codes are now available for workstations, which were not in existence just five years ago. As these changes occur, some organizations will adopt the new codes and analysis techniques, while others will not. This might lead to misunderstandings between thermal shops in different organizations. If thermal analysts make an effort to understand the major differences between the new and old methods, a smoother transition to a more efficient and more versatile thermal analysis environment will be realized.

In Mozambique, integrated community case management (iCCM) of diarrhoea, malaria and pneumonia is embedded in the national community health worker (CHW) programme, mainstreaming it into government policy and service delivery. Since its inception in 1978, the CHW programme has functioned unevenly, was suspended in 1989, but relaunched in 2010. To assess the long-term success of iCCM in Mozambique, this article addresses whether the current CHW programme exhibits characteristics that facilitate or impede its sustainability. We undertook a qualitative case study based on document review (n = 54) and key informant interviews (n = 21) with respondents from the Ministry of Health (MOH), multilateral and bilateral agencies and non-governmental organizations (NGOs) in Maputo in 2012. Interviews were mostly undertaken in Portuguese and all were coded using NVivo. A sustainability framework guided thematic analysis according to nine domains: strategic planning, organizational capacity, programme adaptation, programme monitoring and evaluation, communications, funding stability, political support, partnerships and public health impact. Government commitment was high, with the MOH leading a consultative process in Maputo and facilitating successful technical coordination. The MOH made strategic decisions to pay CHWs, authorize their prescribing abilities, foster guidance development, support operational planning and incorporate previously excluded 'old' CHWs. Nonetheless, policy negotiations excluded certain key actors and uncertainty remains about CHW integration into the civil service and their long-term retention. In addition, reliance on NGOs and donor funding has led to geographic distortions in scaling up, alongside challenges in harmonization. Finally, dependence on external funding, when both external and government funding are declining, may hamper sustainability. Our analysis represents a nuanced assessment of the various domains that influence CHW programme sustainability, highlighting strategic areas such as CHW payment and programme financing. These organizational and contextual determinants of sustainability are central to CHW programme strengthening and iCCM policy support. © The Author 2015.

A study was undertaken into preceptors' perceptions of a preceptorship programme for newly-qualified nurses. The preceptorship programme is designed to enable newly qualified nurses to make the transition from student to registered nurse. Preceptors undergo a training programme to take on the role of preceptor. To evaluate the preceptors' perception of the preceptorship programme. Mixed method evaluative research design was used. This study took place in one National Health Service Healthcare Trust in South West London, UK. Ninety preceptors were invited to participate in the study and the response rate was 44.4% (n=40). The study took place in 2011. Qualitative and quantitative data were collected through questionnaires and one-to-one interviews with a convenience sample of preceptors. Quantitative data were analysed using SPSS, version 18; qualitative data were analysed using the Framework Method. From the quantitative data seven themes emerged. These were preceptors' perceptions of: the personal development of preceptees; the role development of preceptees; the communication skills development of preceptees; the clinical development of preceptees; the development of professional relationships by preceptees; value of the preceptorship programme to the organisation and value of being a preceptor in terms of their own professional development. Qualitative analysis confirmed many of the findings from the statistical analysis and was used to triangulate those findings. The preceptors largely viewed the preceptorship programme and their role within this programme positively. Although difficulties in making time to meet with preceptees was an issue, the preceptorship experience was perceived to have a positive impact on several aspects of preceptee development as well as on the organisation and on the preceptors' own development. The study is unique when mapped against other research studies because there is little in the literature about studies into preceptors' perceptions of preceptorship programmes.

Increased thermal or mechanical stability of DNA duplexes is desired for many applications in nanotechnology or -medicine where DNA is used as a programmable building block. Modifications of pyrimidine bases are known to enhance thermal stability and have the advantage of standard base-pairing and easy integration during chemical DNA synthesis. Through single-molecule force spectroscopy experiments with atomic force microscopy and the molecular force assay we investigated the effect of pyrimidines harboring C-5 propynyl modifications on the mechanical stability of double-stranded DNA. Utilizing these complementary techniques, we show that propynyl bases significantly increase the mechanical stability if the DNA is annealed at high temperature. In contrast, modified DNA complexes formed at room temperature and short incubation times display the same stability as non-modified DNA duplexes. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Despite the recent development in the design of DNA origami, its folding yet relies on thermal or chemical annealing methods. We here demonstrate mechanical folding of the DNA origami structure via a pathway that has not been accessible to thermal annealing. Using magnetic tweezers, we stretch a single scaffold DNA with mechanical tension to remove its secondary structures, followed by base pairing of the stretched DNA with staple strands. When the force is subsequently quenched, folding of the DNA nanostructure is completed through displacement between the bound staple strands. Each process in the mechanical folding is well defined and free from kinetic traps, enabling us to complete folding within 10 min. We also demonstrate parallel folding of DNA nanostructures through multiplexed manipulation of the scaffold DNAs. Our results suggest a path towards programmability of the folding pathway of DNA nanostructures.

The Foundation Programme of the Centre for Science Access at the University of KwaZulu-Natal, South Africa provides access to tertiary science studies to educationally disadvantaged students who do not meet formal faculty entrance requirements. The low number of students proceeding from the programme into mainstream is of concern, particularly given the national imperative to increase participation and levels of performance in tertiary-level science. An attempt was made to understand foundation student performance in a campus of this university, with the view to identifying challenges and opportunities for remediation in the curriculum and processes of selection into the programme. A classification and regression tree analysis was used to identify which variables best described student performance. The explanatory variables included biographical and school-history data, performance in selection tests, and socio-economic data pertaining to their year in the programme. The results illustrate the prognostic reliability of the model used to select students, raise concerns about the inefficiency of school performance indicators as a measure of students' academic potential in the Foundation Programme, and highlight the importance of accommodation arrangements and financial support for student success in their access year.

Evaluation of physical activity programmes for elderly people - a descriptive study using the EFQM' criteria

PubMed Central

2011-01-01

Background In the past years, there has been a growing concern in designing physical activity (PA) programmes for elderly people, because evidence suggests that such health promotion interventions may reduce the deleterious effects of the ageing process. Quality is an important issue when designing a PA programme for older people. Some studies support the Excellence Model of the European Foundation for Quality Management (EFQM) as an operational framework for evaluating the quality of an organization. Within this context, the aim of this study was to characterize the quality management models of the PA programmes developed by Portuguese Local Administration to enhance quality of life for elderly people, according to the criteria of the EFQM Excellence Model. Methods A methodological triangulation was conducted in 26 PA programmes using questionnaire surveys, semi-structured interviews and document analysis. We used standard approaches to the statistical analysis of data including frequencies and percentages for the categorical data. Results Results showed that Processes (65,38%), Leadership (61,03%), Customer results (58,46) and People (51,28%) had high percentage occurrences of quality practices. In contrast, Partnerships and resources (45,77%), People results (41,03%), Policy and strategy (37,91%), Key performance results (19,23%) and Society results (19,23%) had lower percentage occurrences. Conclusions Our findings suggest that although there are some good practices in PA programmes, there are still relevant areas that require improvement. PMID:21338497

To assess the cost-utility of an exercise programme vs usual care after functional multidisciplinary rehabilitation in patients with chronic low back pain. Cost-utility analysis alongside a randomized controlled trial. A total of 105 patients with chronic low back pain. Chronic low back pain patients completing a 3-week functional multidisciplinary rehabilitation were randomized to either a 3-month exercise programme (n = 56) or usual care (n = 49). The exercise programme consisted of 24 training sessions during 12 weeks. At the end of functional multidisciplinary rehabilitation and at 1-year follow-up quality of life was measured with the SF-36 questionnaire, converted into utilities and transformed into quality--adjusted life years. Direct and indirect monthly costs were measured using cost diaries. The incremental cost-effectiveness ratio was calculated as the incremental cost of the exercise programme divided by the difference in quality-adjusted life years between both groups. Quality of life improved significantly at 1-year follow-up in both groups. Similarly, both groups significantly reduced total monthly costs over time. No significant difference was observed between groups. The incremental cost-effectiveness ratio was 79,270 euros. Adding an exercise programme after functional multidisciplinary rehabilitation compared with usual care does not offer significant long-term benefits in quality of life and direct and indirect costs.

Voices of disability on the radio.

2008-01-01

While much commentary exists in relation to the portrayal of disabled people in the media, very little research examines the talk itself in any detail. This paper examines the how people with communication disabilities and disabled people are dealt with in the talk of a radio programme about disability. To show how the voices of disabled people, and in particular people with communication difficulties, are dealt with on a radio programme titled For and About People with Disability (http://www.rte.ie). Analysis of 15 episodes of an Irish radio programme for and about people with disability called Outside the Box to identify frames governing the discourse. Three frames are identified: radio programme frame; presenter frame; and interview frame. Communication disability never appears as a topic in the radio programme frame. In the presenter and interview frames the presenter foregrounds medical aspects of experiences, asks questions that only seek factual information, and fails to respond to subjective aspects of disabled people's experiences. Analysis of the interviewees' responses show how they hold the floor and introduce subjective accounts of living with disability. Frame analysis reveals how disability (including communication disability) is dealt with in the talk of a radio programme for and about people with disability. There is an overemphasis on medical aspects of disability and a view of disability as a primarily physical phenomenon is broadcast. In spite of mainly medical/factual questions, interviewees manage to include rich accounts of their experience. People with communication disability are not included, possibly due to issues of intelligibility or lack of awareness. Speech and language therapists have a valuable role to play in terms of 'learning to listen' and 'helping to tell'.

Yao, Katy; Nkengasong, John N.

2014-01-01

Background Since its introduction in 2009, the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has been implemented in 617 laboratories in 47 countries. Objective We completed a systematic review of the published literature on SLMTA. The review consists of two companion papers; this article examines quantitative evidence presented in the publications along with a meta-analysis of selected results. Methods We identified 28 published articles with data from SLMTA implementation. The SLMTA programme was evaluated through audits based on a standard checklist, which is divided into 12 sections corresponding to the 12 Quality System Essentials (QSEs). Several basic service delivery indicators reported by programmes were also examined. Results for various components of the programme were reviewed and summarised; a meta-analysis of QSE results grouped by the three stages of the quality cycle was conducted for 126 laboratories in 12 countries. Results Global programme data show improved quality in SLMTA laboratories in every country, with average improvements on audit scores of 25 percentage points. Meta-analysis identified Improvement Management as the weakest stage, with internal audit (8%) and occurrence management (16%) showing the lowest scores. Studies documented 19% – 95% reductions in turn-around times, 69% – 93% reductions in specimen rejection rates, 76% – 81% increases in clinician satisfaction rates, 67% – 85% improvements in external quality assessment results, 50% – 66% decreases in nonconformities and 67% increases in staff punctuality. Conclusions The wide array of results reported provides a comprehensive picture of the SLMTA programme overall, suggesting a substantive impact on provision of quality laboratory services and patient care. These comprehensive results establish a solid data-driven foundation for program improvement and further expansion. PMID:29043201

Collaborative care programmes lead to better outcomes in the management of depression. A programme of this nature has demonstrated its effectiveness in primary care in Spain. Our objective was to evaluate the cost-effectiveness of this programme compared to usual care. A bottom-up cost-effectiveness analysis was conducted within a randomized controlled trial (2007-2010). The intervention consisted of a collaborative care programme with clinical, educational and organizational procedures. Outcomes were monitored over a 12 months period. Primary outcomes were incremental cost-effectiveness ratios (ICER): mean differences in costs divided by quality-adjusted life years (QALY) and mean differences in costs divided by depression-free days (DFD). Analyses were performed from a healthcare system perspective (considering healthcare costs) and from a society perspective (including healthcare costs plus loss of productivity costs). Three hundred and thirty-eight adult patients with major depression were assessed at baseline. Only patients with complete data were included in the primary analysis (166 in the intervention group and 126 in the control group). From a healthcare perspective, the average incremental cost of the programme compared to usual care was €182.53 (p<0.001). Incremental effectiveness was 0.045 QALY (p=0.017) and 40.09 DFD (p=0.011). ICERs were €4,056/QALY and €4.55/DFD. These estimates and their uncertainty are graphically represented in the cost-effectiveness plane. The amount of 13.6% of patients with incomplete data may have introduced a bias. Available data about non-healthcare costs were limited, although they may represent most of the total cost of depression. The intervention yields better outcomes than usual care with a modest increase in costs, resulting in favourable ICERs. This supports the recommendation for its implementation.

Brown, A M

2001-06-01

The objective of this present study was to introduce a simple, easily understood method for carrying out non-linear regression analysis based on user input functions. While it is relatively straightforward to fit data with simple functions such as linear or logarithmic functions, fitting data with more complicated non-linear functions is more difficult. Commercial specialist programmes are available that will carry out this analysis, but these programmes are expensive and are not intuitive to learn. An alternative method described here is to use the SOLVER function of the ubiquitous spreadsheet programme Microsoft Excel, which employs an iterative least squares fitting routine to produce the optimal goodness of fit between data and function. The intent of this paper is to lead the reader through an easily understood step-by-step guide to implementing this method, which can be applied to any function in the form y=f(x), and is well suited to fast, reliable analysis of data in all fields of biology.

Although advance care planning (ACP) and the use of advanced care directives (ACD) and end-of-life care plans are associated with a reduction in inappropriate hospitalisation, there is little evidence supporting the economic benefits of such programmes. We assessed the economic impact (gross savings) of the Let Me Decide (LMD) ACP programme in Ireland, specifically the impact on hospitalisations, bed days and location of resident deaths, before and after systematic implementation of the LMD-ACP combined with a palliative care education programme. The LMD-ACP was introduced into three long-term care (LTC) facilities in Southern Ireland and outcomes were compared pre and post implementation. In addition, 90 staff were trained in a palliative care educational programme. Economic analysis including probabilistic sensitivity analysis was performed. The uptake of an ACD or end-of-life care post-implementation rose from 25 to 76%. Post implementation, there were statistically significant decreases in hospitalisation rates from baseline (hospitalisation incidents declined from 27.8 to 14.6%, z = 3.96, p < 0.001; inpatient hospital days reduced from 0.54 to 0.36%, z = 8.85, p < 0.001). The percentage of hospital deaths also decreased from 22.9 to 8.4%, z = 3.22, p = 0.001. However, length of stay (LOS) increased marginally (7-9 days). Economic analysis suggested a cost-reduction related to reduced hospitalisations ranging between €10 and €17.8 million/annum and reduction in ambulance transfers, estimated at €0.4 million/annum if these results were extrapolated nationally. When unit costs and LOS estimates were varied in scenario analyses, the expected cost reduction owing to reduced hospitalisations, ranged from €17.7 to €42.4 million nationally. Implementation of the LMD-ACP (ACD/end-of-life care plans combined with palliative care education) programme resulted in reduced rates of hospitalisation. Despite an increase in LOS, likely reflecting more complex care needs of admitted residents, gross costs were reduced and scenario analysis projected large annual savings if these results were extrapolated to the wider LTC population in Ireland.

Transient thermal analysis of a titanium multiwall thermal protection system

Blosser, M. L.

1982-01-01

The application of the SPAR thermal analyzer to the thermal analysis of a thermal protection system concept is discussed. The titanium multiwall thermal protection system concept consists of alternate flat and dimpled sheets which are joined together at the crests of the dimples and formed into 30 cm by 30 cm (12 in. by 12 in.) tiles. The tiles are mechanically attached to the structure. The complex tile geometry complicates thermal analysis. Three modes of heat transfer were considered: conduction through the gas inside the tile, conduction through the metal, and radiation between the various layers. The voids between the dimpled and flat sheets were designed to be small enough so that natural convection is insignificant (e.g., Grashof number 1000). A two step approach was used in the thermal analysis of the multiwall thermal protection system. First, an effective normal (through-the-thickness) thermal conductivity was obtained from a steady state analysis using a detailed SPAR finite element model of a small symmetric section of the multiwall tile. This effective conductivity was then used in simple one dimensional finite element models for preliminary analysis of several transient heat transfer problems.

The gene and the genon concept: a functional and information-theoretic analysis

PubMed Central

Scherrer, Klaus; Jost, Jürgen

2007-01-01

‘Gene' has become a vague and ill-defined concept. To set the stage for mathematical analysis of gene storage and expression, we return to the original concept of the gene as a function encoded in the genome, basis of genetic analysis, that is a polypeptide or other functional product. The additional information needed to express a gene is contained within each mRNA as an ensemble of signals, added to or superimposed onto the coding sequence. To designate this programme, we introduce the term ‘genon'. Individual genons are contained in the pre-mRNA forming a pre-genon. A genomic domain contains a proto-genon, with the signals of transcription activation in addition to the pre-genon in the transcripts. Some contain several mRNAs and hence genons, to be singled out by RNA processing and differential splicing. The programme in the genon in cis is implemented by corresponding factors of protein or RNA nature contained in the transgenon of the cell or organism. The gene, the cis programme contained in the individual domain and transcript, and the trans programme of factors, can be analysed by information theory. PMID:17353929

To examine the experiences of mental health service users who took part in an arts-based programme at Tate Modern, a major London art gallery. Exploratory qualitative design. Data were collected using in-depth semi-structured interviews with 10 mental health service users who had taken part in a community-based programme at Tate Modern. Additionally, six art educators from Tate Modern were interviewed. Concepts that emerged from the text were identified using thematic analysis. All participants valued the gallery-based programme. The three overarching thematic areas were: the symbolic and physical context in which the programme workshops were located; the relational and social context of the programme workshops; and reflections on the relationship between the arts-based programme and subsequent mental health. Art galleries are increasingly seen to function as vehicles for popular education with mental health service users. This study adds to the growing body of evidence related to how mental health service users experience and reflect on arts-related programmes targeted at them. This study indicates that emphasis on how users experience gallery-based programmes may contribute to a more nuanced understanding of the relationship between art and mental health.

Bridge deck surface temperature monitoring by infrared thermography and inner structure identification using PPT and PCT analysis methods

Dumoulin, Jean

2013-04-01

One of the objectives of ISTIMES project was to evaluate the potentialities offered by the integration of different electromagnetic techniques able to perform non-invasive diagnostics for surveillance and monitoring of transport infrastructures. Among the EM methods investigated, we focused our research and development efforts on uncooled infrared camera techniques due to their promising potential level of dissemination linked to their relative low cost on the market. On the other hand, works were also carried out to identify well adapted implementation protocols and key limits of Pulse Phase Thermography (PPT) and Principal Component Thermography (PCT) processing methods to analyse thermal image sequence and retrieve information about the inner structure. So the first part of this research works addresses infrared thermography measurement when it is used in quantitative mode (not in laboratory conditions) and not in qualitative mode (vision applied to survey). In such context, it requires to process in real time thermal radiative corrections on raw data acquired to take into account influences of natural environment evolution with time, thanks to additional measurements. But, camera sensor has to be enough smart to apply in real time calibration law and radiometric corrections in a varying atmosphere. So, a complete measurement system was studied and developed [1] with low cost infrared cameras available on the market. In the system developed, infrared camera is coupled with other sensors to feed simplified radiative models running, in real time, on GPU available on small PC. The whole measurement system was implemented on the "Musmeci" bridge located in Potenza (Italy). No traffic interruption was required during the mounting of our measurement system. The infrared camera was fixed on top of a mast at 6 m elevation from the surface of the bridge deck. A small weather station was added on the same mast at 1 m under the camera. A GPS antenna was also fixed at the basis of the mast and at a same elevation than the bridge deck surface. This trial took place during 4 days, but our system was leaved in stand alone acquisition mode only during 3 days. Thanks to the software developed and the small computer hardware used, thermal image were acquired at a frame rate of 0.1 Hz by averaging 50 thermal images leaving the original camera frame rate fixed at 5 Hz. Each hour, a thermal image sequence was stored on the internal hard drive and data were also retrieved, on demand, by using a wireless connection and a tablet PC. In the second part of this work, thermal image sequences analysis was carried out. Two analysis approaches were studied: one based on the use of the Fast Fourier Transform [2] and the second one based on the Principal Component Analysis [3-4]. Results obtained show that the inner structure of the deck was identified though thermal images were affected by the fact that the bridge was open to traffic during the whole experiments duration.

To develop and evaluate the effects of a web-based education programme in early childhood for children with atopic dermatitis. The prevalence rate of atopic dermatitis is highest in early childhood. A holistic approach is urgently needed for young children with respect to disease severity, quality of life and management, particularly parental knowledge about atopic dermatitis and adherence to treatment. A quasi-experimental study design was used. A total of 40 mother-child dyads participated in the study from 1 July-30 November 2011 in Korea. All children were under 3 years of age. The programme was based on the Network-Based Instructional System Design model, which consists of five phases: analysis, design, development, implementation and evaluation. The experimental group participated in the programme for 2 weeks. Participants took part in a learning session during the first week and then conducted the practice session at home during the second week. Participant knowledge and compliance were evaluated through online quizzes and self-checklists. Statistical analyses (chi-square test and t-test) were performed using the Statistical Analysis System, Version 9.13. There was a significant improvement in disease severity, quality of life and mothers' self-efficacy in the experimental group; thus, the web-based education programme was effective. The web-based education programme as an advanced intervention may be useful in providing basic data for future atopic dermatitis-related studies. Moreover, the programme may serve as a nursing educational intervention tool for clinical nursing practices. © 2014 John Wiley & Sons Ltd.

Searching for the mechanisms of change: a protocol for a realist review of batterer treatment programmes

Introduction Conflicting results reported by evaluations of typical batterer intervention programmes leave many judicial officials and policymakers uncertain about the best way to respond to domestic violence, and whether to recommend and fund these programmes. Traditional evaluations and systematic reviews tend to focus predominantly on whether the programmes ‘worked’ (eg, reduced recidivism) often at the exclusion of understanding for whom they may or may not have worked, under what circumstances, and why. Methods and analysis We are undertaking a realist review of the batterer treatment programme literature with the aim of addressing this gap. Keeping with the goals of realist review, our primary aims are to identify the theory that underlies these programmes, highlight the mechanisms that trigger changes in participant behaviour and finally explain why these programmes help some individuals reduce their use of violence and under what conditions they are effective or not effective. We begin by describing the process of perpetrator treatment, and by proposing an initial theoretical model of behaviour change that will be tested by our review. We then describe the criteria for inclusion of an evaluation into the review, the search strategy we will use to identify the studies, and the plan for data extraction and analysis. Ethics and dissemination The results of this review will be written up using the RAMESES Guidelines for Realist Synthesis, and disseminated through peer-reviewed publications aimed at the practitioner community as well as presented at community forums, and at violence against women conferences. Ethics approval was not needed. PMID:27053268

The South Pacific region is experiencing significant rates of chronic diseases. Well-evaluated health promotion programmes are needed as a central piece of a strategic solution. Just as important as the evaluation itself is how that evaluation outcome can be communicated for future programme use by local programme planners. The objective of this study is to evaluate a physical activity (PA) programme that was designed for Pacific women in urban Vanuatu, and subsequently to develop new techniques to display data that support the understanding and communication of programme success and challenges. Data collection methods included quantitative Likert scale questions and qualitative open-ended questions. A new analysis technique visualises open-ended process evaluation data. We present themes using word sizes proportional to the frequency of the themes identified through thematic analysis. The Likert scale technique revealed little meaningful information; almost all participants rated most elements of the programme highly. This may be related to Pacific people being frequently inclined to assent with external ideas. Open-ended questions provided more significant insights. For example, we found a stronger change in eating habits (68.9%) than in exercise behaviour (28.2%). We present an evaluation of the first pedometer-based PA intervention in the Pacific and respond to the paucity of process evaluations that have been carried out in the context of low- and middle-income countries. Moreover, the new thematic data visualisation (TDV) approach may aid in understanding complex and cluttered data in a constructive and coordinated way; we present a new approach in health promotion research. © The Author(s) 2014.

Breeding programmes described as community-based (CBBP) typically relate to low-input systems with farmers having a common interest to improve and share their genetic resources. CBBPs are more frequent with keepers of small ruminants, in particular smallholders of local breeds, than with cattle, pigs or chickens with which farmers may have easier access to alternative programmes. Constraints that limit the adoption of conventional breeding technologies in low-input systems cover a range of organizational and technical aspects. The analysis of 8 CBBPs located in countries of Latin-America, Africa and Asia highlights the importance of bottom-up approaches and involvement of local institutions in the planning and implementation stages. The analysis also reveals a high dependence of these programmes on organizational, technical and financial support. Completely self-sustained CBBPs seem to be difficult to realize. There is a need to implement and document formal socio-economic evaluations of CBBPs to provide governments and other development agencies with the information necessary for creating sustainable CBBPs at larger scales. © 2015 Blackwell Verlag GmbH.

Public sentiment from social media like Twitter can be used as one of the indicators to determine the quality of TV Programmes. In this study, we implemented information extraction on Twitter by using sentiment analysis method to assess the quality of TV Programmes. The first stage of this study is pre-processing which consists of cleansing, case folding, tokenizing, stop-word removal, stemming, and redundancy filtering. The next stage is weighting process for every single word by using TF-IDF method. The last step of this study is the sentiment classification process which is divided into three sentiment category which is positive, negative and neutral. We classify the TV programmes into several categories such as news, children, or films/soap operas. We implemented an improved k-nearest neighbor method in classification 4000 twitter status, for four biggest TV stations in Indonesia, with ratio 70% data for training and 30% of data for the testing process. The result obtained from this research generated the highest accuracy with k=10 as big as 90%.

The article describes a framework and the process for the development of the peer-based mental health support programme and its implementation. The development of a peer-based mental health support programme is based on Erikson's theory on the adolescent phase of development, the psycho-educational processes; the peer approach and the orphaned adolescents lived experiences as conceptual framework. A triangulation of five qualitative methods of photography, reflective diaries, focus groups, event history calendar and field notes were used to capture the lived experiences of adolescents orphaned to HIV and AIDS. Analysis of data followed Colaizzi's method of data analysis. The combination of psycho-education, Erikson's stages of development and peer support assisted the participants to gain knowledge and skills to overcome adversity and to assist them to become to more resilient. The peer based mental health support programme if used would enhance the mental health of adolescent orphans.

The paper describes a thermal-structural design analysis study of a fuel-injection strut for a hydrogen-cooled scramjet engine for a supersonic transport, utilizing finite-element methodology. Applications of finite-element and finite-difference codes to the thermal-structural design-analysis of space transports and structures are discussed. The interaction between the thermal and structural analyses has led to development of finite-element thermal methodology to improve the integration between these two disciplines. The integrated thermal-structural analysis capability developed within the framework of a computer code is outlined.

2018-04-01

The Gambling Act 2003 mandated a public health strategy for preventing and minimising gambling harm in New Zealand. Aware Communities and Supportive Communities are two public health programmes subsequently implemented nationwide. These programmes differed from common health promotion initiatives such as media or education campaigns as they were community-action based (requiring community involvement in programme planning and delivery). We carried out a process evaluation to determine their implementation effectiveness and inform improvement and future programme planning. Our qualitative dominant mixed methods design comprised analysis of over a hundred implementer progress reports (submitted July 2010 - June 2013), a staff survey and a staff focus group interview. The programmes demonstrated capacity to not only achieve expected outcomes (e.g. enhanced community awareness about harmful gambling), but also to enhance social sustainability at the community level (e.g. established trustful relationships) and achieve some programme sustainability (e.g. community ownership over ongoing programme delivery). The evaluation noted the potential for a sustainable gambling harm-minimisation model. Community-action based harm-minimisation programmes offer programme sustainability potential which in turn offers funding cost-effectiveness when there are continual public health outcomes beyond initial funding. Although resource intensive, the community-action based approach enables culturally appropriate public health programmes suitable for societies where specific ethnic groups have higher gambling risk. Recognition of such harm-minimisation programmes' contribution to social sustainability is important considering the potential for broader public health outcomes (e.g. better life quality, lesser social problems) within socially sustainable societies.

An assessment of the effect of an experimental environmental education programme (Man and Nutrition) on Kuwaiti primary school pupils (Grade Four)

Esmaeel, Yaqoub Y. R.

The educational system in Kuwait is undergoing some fundamental changes, and the need for reform of environmental education has become urgent as a result of the concerns of both the government and the public over environmental issues. It is in such a context that this research was conducted. The research was intended to develop, implement, and evaluate an experimental programme Man and Nutrition for Kuwaiti primary school pupils, aimed at developing a positive environmental achievement, Information about the present status of environmental concepts and environmental education in Kuwait was obtained from preliminary study such as interviews and curriculum analysis. Interviews were conducted in ten different primary schools in four districts in Kuwait, which involved 31 pupils in total, hi addition, information was obtained by analysis of the science curriculum for fourth grade primary schools. The preliminary study was carried out during the period April to October 1998. The results of the preliminary study served to aid the development of an experimental teaching programme. The experimental programme Man and Nutrition consisted of eight lessons printed in two booklets, a teacher's guide and pupil's textbook. The research included a review of the relevant literature examining the development of environmental programmes and activities in a number of countries, which were selected because of their environmental education approaches, and the variety of their environmental conditions. Pilot testing of the teaching programmes was carried out to ascertain the appropriateness of the materials and the data collecting instruments used for the evaluation of the main experimental study. The main study group included 115 pupils in four primary schools and four teachers selected in Kuwait. Data collecting included pre and post-tests and the course evaluation by teachers using semi-structured interviews. Statistical analysis of data obtained was carried out using the SPSS/PC+ computer programme. The major results of this study indicated that: (1) The present science programme of the fourth grade does not sufficiently cover the concepts identified as environmental concepts. (2) The experimental programme was significantly effective in increasing the pupils' knowledge regarding the environmental programme Man and Nutrition. (3) A significant difference in the mean scores was found between boys and girls in the post-achievement test. (4) There was a significant difference in the pupils' mean scores between the educational districts in the post-achievement test. (5) The experimental programme had similar influences on pupils' overall achievement by parents' education. Based upon the above major research results, the study puts forward some practical recommendations regarding the development of a school environmental education programme. Since the study is one of the first of its kind in Kuwait, it also suggests a few possible areas for future research. It is hoped that the research will lead to a worthwhile primary school environmental education.

To determine whether the clinical competencies of musculoskeletal outpatient physiotherapists improve if they participate in an annual in-service education programme designed around clinical practice needs. A within-subject, without-control, experimental, pre-test post-test study. Clinical and educational facilities of Doncaster and Bassetlaw Hospitals NHS Foundation Trust and locality-based outpatient facilities. Participants were 37 specialist musculoskeletal outpatient physiotherapists (band 6 and 7), working for Doncaster and Bassetlaw Hospitals NHS Foundation Trust. Participants completed three separate modules of in-service education through an academic year, based on learning outcomes identified from observation and performance rating of their clinical competencies. Each module lasted 7 hours, with supporting clinical assistance sessions and self-directed learning time. The primary outcome measure was a (participant) performance rating (from novice to expert) of 20 clinical competencies scored by experienced clinical educators before and after completion of the in-service education programme. A secondary, qualitative outcome measure (a purpose-made, semi-structured questionnaire) given after the programme explored participants' experiences and perceptions of the in-service education programme. Seven competencies were identified as the focus of the programme because their performance ratings were the lowest. All seven of these competencies improved following the programme. Communication scores improved by 6%, clinical reasoning by 4%, functional analysis of movement by 6%, use of research in practice by 4%, and critical appraisal of evidence by 4.6%. Performance of structural differentiation and the range of manual handling skills demonstrated were the only competencies to show a statistically significant improvement of 14.6% and 12%, respectively (p≤0.025(. Thematic analysis of the questionnaires revealed that 96% of respondents felt that their practice had changed positively over the year because of the programme. Providing a structured and bespoke in-service education programme over an academic year may help to improve the rating of clinical competencies and give participants the perception that their clinical practice has changed because of the programme.

Online estimation of internal stack temperatures in solid oxide fuel cell power generating units

2016-12-01

Thermal stress is one of the main factors affecting the degradation rate of solid oxide fuel cell (SOFC) stacks. In order to mitigate the possibility of fatal thermal stress, stack temperatures and the corresponding thermal gradients need to be continuously controlled during operation. Due to the fact that in future commercial applications the use of temperature sensors embedded within the stack is impractical, the use of estimators appears to be a viable option. In this paper we present an efficient and consistent approach to data-driven design of the estimator for maximum and minimum stack temperatures intended (i) to be of high precision, (ii) to be simple to implement on conventional platforms like programmable logic controllers, and (iii) to maintain reliability in spite of degradation processes. By careful application of subspace identification, supported by physical arguments, we derive a simple estimator structure capable of producing estimates with 3% error irrespective of the evolving stack degradation. The degradation drift is handled without any explicit modelling. The approach is experimentally validated on a 10 kW SOFC system.

Programme Costing of a Physical Activity Programme in Primary Prevention: Should the Costs of Health Asset Assessment and Participatory Programme Development Count?

PubMed Central

Wolfenstetter, Silke B.; Schweikert, Bernd; John, Jürgen

2012-01-01

This analysis aims to discuss the implications of the “health asset concept”, introduced by the WHO, and the “investment for health model” requiring a “participatory approach” of cooperative programme development applied on a physical activity programme for socially disadvantaged women and to demonstrate the related costing issues as well as the relevant decision context. The costs of programme implementation amounted to €48,700. Adding the costs for developing the programme design of €48,800 results in total costs of €97,500; adding on top of that the costs of asset assessment running to €35,600 would total €133,100. These four different cost figures match four different types of potentially relevant decisions contexts. Depending on the decision context the total costs, and hence the incremental cost-effectiveness ratio of a health promotion intervention, could differ considerably. Therefore, a detailed cost assessment and the identification of the decision context are of crucial importance. PMID:22536517

The aim was to undertake a cost-utility analysis of a self-management programme of activity, coping and education (SPACE) for chronic obstructive pulmonary disease (COPD). The analysis was conducted alongside a six-month randomized controlled trial in 30 primary care settings. The economic analysis used data from 184 patients with confirmed diagnosis of COPD, forced expiratory volume in one second/forced vital capacity ratio <0.7 and with grade 2-5 on the Medical Research Council dyspnoea scale. Participants received either a self-management programme consisting of an education manual (SPACE for COPD) and consultation or usual care. Six-month costs were estimated from the National Health Service and Personal Social Services perspective and quality-adjusted life years (QALYs) were calculated based on patient responses at baseline and six months.The mean difference in costs between usual care and SPACE FOR COPD programme was -£27.18 (95% confidence interval (CI); -£122.59 to £68.25) while mean difference in QALYs was -0.10 (95% CI; -0.17 to -0.02). The results suggest that the intervention is more costly and more effective than usual care. The probability of the intervention being cost-effective was 97% at a threshold of £20,000/QALY gained. We conclude that the SPACE FOR COPD programme is cost-effective compared to usual care. © The Author(s) 2015.

An ultrastretchable thermistor that combines intrinsic stretchability, thermal sensitivity, transparency, and self-healing capability is fabricated. It is found the polyacrylamide/carrageenan double network (DN) hydrogel is highly sensitive to temperature and therefore can be exploited as a novel channel material for a thermistor. This thermistor can be stretched from 0 to 330% strain with the sensitivity as high as 2.6%/°C at extreme 200% strain. Noticeably, the mechanical, electrical, and thermal sensing properties of the DN hydrogel can be self-healed, analogous to the self-healing capability of human skin. The large mechanical deformations, such as flexion and twist with large angles, do not affect the thermal sensitivity. Good flexibility enables the thermistor to be attached on nonplanar curvilinear surfaces for practical temperature detection. Remarkably, the thermal sensitivity can be improved by introducing mechanical strain, making the sensitivity programmable. This thermistor with tunable sensitivity is advantageous over traditional rigid thermistors that lack flexibility in adjusting their sensitivity. In addition to superior sensitivity and stretchability compared with traditional thermistors, this DN hydrogel-based thermistor provides additional advantages of good transparency and self-healing ability, enabling it to be potentially integrated in soft robots to grasp real world information for guiding their actions.

Hawaiian volcanoes are highly accessible and well monitored by ground instruments. Nevertheless, observational gaps remain and thermal satellite imagery has proven useful in Hawai‘i for providing synoptic views of activity during intervals between field visits. Here we describe the beginning of a thermal remote sensing programme at the US Geological Survey Hawaiian Volcano Observatory (HVO). Whereas expensive receiving stations have been traditionally required to achieve rapid downloading of satellite data, we exploit free, low-latency data sources on the internet for timely access to GOES, MODIS, ASTER and EO-1 ALI imagery. Automated scripts at the observatory download these data and provide a basic display of the images. Satellite data have been extremely useful for monitoring the ongoing lava flow activity on Kīlauea's East Rift Zone at Pu‘u ‘Ō‘ō over the past few years. A recent lava flow, named Kahauale‘a 2, was upslope from residential subdivisions for over a year. Satellite data helped track the slow advance of the flow and contributed to hazard assessments. Ongoing improvement to thermal remote sensing at HVO incorporates automated hotspot detection, effusion rate estimation and lava flow forecasting, as has been done in Italy. These improvements should be useful for monitoring future activity on Mauna Loa.

The main determinants of community participation in disease control programmes are identified and a framework with eleven variables is developed. Attention is drawn to the political background, community characteristics, the managerial capacity of the provider and the epidemiology of the disease. The framework is designed to guide health professionals in the systematic assessment and monitoring of participation in disease control programmes. Analysis of the Ghanaian Guinea Worm Eradication Programme and the Nicaraguan Tuberculosis Control Programme are presented as case studies. They show that political support does not guarantee community participation in disease control programmes and stress the importance of other determinants such as commitment to PHC, intersectoral coordination, the project approach and human resources. The relevance of the epidemiology of the disease in determining what degree of community participation will be most effective is highlighted by the case studies.

Although the scientific disciplines conduct practical work in different ways, all consider practical work as the essential way of connecting objects and phenomena with ideas and the abstract. Accordingly, practical work is regarded as central to science education as well. We investigate a practical, object-based palaeontology programme at a natural history museum to identify how palaeontological objects prompt scientific activity among upper secondary school students. We first construct a theoretical framework based on an analysis of the programme's palaeontological content. From this, we build our reference model, which considers the specimens used in the programme, possible palaeontological interpretations of these specimens, and the conditions inherent in the programme. We use the reference model to analyse the activities of programme participants, and illustrate how these activities are palaeontologically authentic. Finally, we discuss our findings, examining the mechanism by which the specimens prompt scientific activities. We also discuss our discipline-based approach, and how it allows us to positively identify participants' activities as authentic. We conclude by discussing the implications of our findings.

The purpose of the present analysis was to examine secular trends in school performance indicators in relationship to the implementation of a programme targeting the school food and physical activity environment. Data on available school performance indicators were obtained; retrospective analyses were conducted to assess trends in indicators in association with programme implementation; each outcome was regressed v. year, beginning with the year prior to programme implementation. The Healthy Kids, Smart Kids programme, a grass-roots effort to enhance the school food and physical activity environment in the Browns Mill Elementary School in Georgia. Data included publicly available school records from the years 1995 to 2006. The number of nurse, counselling and disciplinary referrals per 100 students demonstrated a downward trend, while standardized test scores demonstrated an upward trend beginning in the year of programme implementation. School year was a significant predictor of all indicators. Promoting nutrition and physical activity within the school environment may be a promising approach for enhancing both student health and educational outcomes.

The Victorian Country Fire Authority in Australia runs the Community Fireguard (CFG) programme to assist individuals and communities in preparing for fire. The objective of this qualitative research was to understand the impact of CFG groups on their members' fire preparedness and response during the 2009 Australian bushfires. Social connectedness emerged as a strong theme, leading to an analysis of data using social capital theory. The main strength of the CFG programme was that it was driven by innovative community members; however, concerns arose regarding the extent to which the programme covered all vulnerable areas, which led the research team to explore the theory of diffusion of innovation. The article concludes by stepping back from the evaluation and using both applied theories to reflect on broad options for community fire preparedness programmes in general. The exercise produced two contrasting options for principles underlying community fire preparedness programmes. © 2014 The Author(s). Disasters © Overseas Development Institute, 2014.

Support for All in the UK Work Programme? Differential Payments, Same Old Problem

2014-01-01

The UK has been a high profile policy innovator in welfare-to-work provision which has led in the Coalition government's Work Programme to a fully outsourced, ‘black box’ model with payments based overwhelmingly on job outcome results. A perennial fear in such programmes is providers' incentives to ‘cream’ and ‘park’ claimants, and the Department for Work and Pensions has sought to mitigate such provider behaviours through Work Programme design, particularly via the use of claimant groups and differential pricing. In this article, we draw on a qualitative study of providers in the programme alongside quantitative analysis of published performance data to explore evidence around creaming and parking. The combination of the quantitative and qualitative evidence suggest that creaming and parking are widespread, seem systematically embedded within the Work Programme, and are driven by a combination of intense cost-pressures and extremely ambitious performance targets alongside overly diverse claimant groups and inadequately calibrated differentiated payment levels.

In comprehensive two-dimensional gas chromatography (GC x GC), a modulator is placed at the juncture between two separation columns to focus and re-inject eluting mixture components, thereby enhancing the resolution and the selectivity of analytes. As part of an effort to develop a microGC x microGC prototype, in this report we present the design, fabrication, thermal operation, and initial testing of a two-stage microscale thermal modulator (microTM). The microTM contains two sequential serpentine Pyrex-on-Si microchannels (stages) that cryogenically trap analytes eluting from the first-dimension column and thermally inject them into the second-dimension column in a rapid, programmable manner. For each modulation cycle (typically 5 s for cooling with refrigeration work of 200 J and 100 ms for heating at 10 W), the microTM is kept approximately at -50 degrees C by a solid-state thermoelectric cooling unit placed within a few tens of micrometres of the device, and heated to 250 degrees C at 2800 degrees C s(-1) by integrated resistive microheaters and then cooled back to -50 degrees C at 250 degrees C s(-1). Thermal crosstalk between the two stages is less than 9%. A lumped heat transfer model is used to analyze the device design with respect to the rates of heating and cooling, power dissipation, and inter-stage thermal crosstalk as a function of Pyrex-membrane thickness, air-gap depth, and stage separation distance. Experimental results are in agreement with trends predicted by the model. Preliminary tests using a conventional capillary column interfaced to the microTM demonstrate the capability for enhanced sensitivity and resolution as well as the modulation of a mixture of alkanes.

Monitoring and assessment of the outdoor thermal comfort in Bucharest (Romania)

2017-04-01

Bucharest is one of the European cities most at risk of being affected by meteorological hazards. Heat or cold waves, extreme temperature events, heavy rains or prolonged precipitation deficits are all-season phenomena, triggering damages, discomfort or even casualties. Temperature hazards may occur annually and challenge equally the public, local business and administration to find adequate solutions for securing the thermal comfort in the outdoor environment of the city. The accurate and fine resolution monitoring of the air temperature pledges for the comprehensive assessment of the thermal comfort in order to capture as much as possible the urban influence. This study uses sub-hourly temperature data (10-min temporal resolution) retrieved over the period November 2014 - November 2016 collected from nine sensors placed either in plain urban conditions or within the three meteorological stations of the national network which are currently monitoring the climate of Bucharest (Băneasa, Filaret, Afumați). The relative humidity was estimated based on the data available at the three stations placed in WMO standard conditions, and the 10-min values of 8 Thermal Comfort Indices were computed, namely: Heat Index, Humidex, Relative Strain Index, Scharlau, Summer Simmer Index, Physiological Equivalent Index, Temperature-Humidity Index, Thom Discomfort Index. The indices were analysed statistically, both individually and combined. Despite the short range of the available data, this study emphasizes clear spatial differentiations of the thermal comfort, in a very good agreement with the land cover and built zones of the city, while important variations were found in the temporal regime, due to large variations of the temperature values (e.g. >4 centigrade between consecutive hours or >15 centigrade between consecutive days). Ultimately, this study has revealed that the continuous monitoring of the urban climate, at fine temporal and spatial resolution, may deliver fundamental information for supporting the immediate measures and the long-term urban planning and the sustainable thermal comfort of the urban inhabitants.

2001-01-01

Heat transfer, thermal stresses, and thermal buckling analyses were performed on the unconventional wing structures of a Hyper-X hypersonic flight research vehicle (designated as X-43) subjected to nominal Mach 7 aerodynamic heating. A wing midspan cross section was selected for the heat transfer and thermal stress analyses. Thermal buckling analysis was performed on three regions of the wing skin (lower or upper); 1) a fore wing panel, 2) an aft wing panel, and 3) a unit panel at the middle of the aft wing panel. A fourth thermal buckling analysis was performed on a midspan wing segment. The unit panel region is identified as the potential thermal buckling initiation zone. Therefore, thermal buckling analysis of the Hyper-X wing panels could be reduced to the thermal buckling analysis of that unit panel. "Buckling temperature magnification factors" were established. Structural temperature-time histories are presented. The results show that the concerns of shear failure at wing and spar welded sites, and of thermal buckling of Hyper-X wing panels, may not arise under Mach 7 conditions.

2018-04-09

Despite criticisms that many quality improvement (QI) initiatives fail due to incomplete programme theory, there is no defined way to evaluate how programme theory has been articulated. The objective of this research was to develop, and assess the usability and reliability of scoring criteria to evaluate programme theory diagrams. Criteria development was informed by published literature and QI experts. Inter-rater reliability was tested between two evaluators. About 63 programme theory diagrams (42 driver diagrams and 21 action-effect diagrams) were reviewed to establish whether the criteria could support comparative analysis of different approaches to constructing diagrams. Components of the scoring criteria include: assessment of overall aim, logical overview, clarity of components, cause-effect relationships, evidence and measurement. Independent reviewers had 78% inter-rater reliability. Scoring enabled direct comparison of different approaches to developing programme theory; action-effect diagrams were found to have had a statistically significant but moderate improvement in programme theory quality over driver diagrams; no significant differences were observed based on the setting in which driver diagrams were developed. The scoring criteria summarise the necessary components of programme theory that are thought to contribute to successful QI projects. The viability of the scoring criteria for practical application was demonstrated. Future uses include assessment of individual programme theory diagrams and comparison of different approaches (e.g. methodological, teaching or other QI support) to produce programme theory. The criteria can be used as a tool to guide the production of better programme theory diagrams, and also highlights where additional support for QI teams could be needed.

The purpose of this study was to determine the feasibility of providing a community-based aquatic exercise programme and to examine the effects of a group aquatic exercise programme in individuals with multiple sclerosis. This study illustrates the implementation of a multidisciplinary community-based programme in a university community wellness centre coordinated with a local advocacy group. Eleven subjects with multiple sclerosis participated in a 5-week community-based aquatic exercise programme. Aquatic exercises were held twice weekly for 60 minutes and included aerobic exercises, strength training, flexibility exercises, balance training and walking activities. The 10-Metre Walk test, the Berg Balance Scale (BBS), the 'Timed Up and Go' (TUG) test, grip strength and the Modified Fatigue Impact Scale were used to assess motor function. Analysis of the scores demonstrated improved gait speed, BBS, TUG test and grip strength. The average attendance of the training sessions was good (88%), and no incidence of injuries, no incidence of falls and no adverse effects related to the exercise programme were reported. All participants reported that they enjoyed the programme, and they had improved after the training. A community-based aquatic exercise programme is feasible and resulted in improvement in motor functions of individuals with multiple sclerosis. These findings indicate that an aquatic training programme is appropriate and beneficial for individuals with multiple sclerosis and should be considered to augment the rehabilitation of those individuals. This programme may provide a viable model for a community-based wellness programme for people with disability including individuals with multiple sclerosis.

Health promotion programme in the private workplaces in Singapore: a prevalence survey.

Chew, L; Cheah, C; Koh, Y H

2002-01-01

A postal survey was conducted in 4,479 private companies with at least 50 employees in 1998 to determine the prevalence and the scope of workplace health promotion programme in these companies in Singapore. The self-administered questionnaire mailed to the study population covered five areas viz, organisational details, workplace health policies, health promotion and related activities, workplace health facilities and the source of assistance for the programme. The overall response was 49.5%. Parkinson's definition of workplace health promotion was used in the analysis to determine the prevalence of the programme. The data was collated on DBase IV and analysed using SPSS computer programmes. About one third of the respondents covering an estimated 26% of the private sector workforce had a comprehensive workplace health promotion programme as defined by Parkinson. This prevalence was a function of workforce size and industry type. Workplaces with larger workforce size (p<0.001) and those from the manufacturing and human/health service sectors (p<0.001) were more likely to have such programmes compared to their smaller counterparts and other industries respectively. The management remained the main driver behind these programmes. Many of the programmes were centred around health promoting policies and facilities with emphasis on occupational healthl safety and smoking issues. A significant proportion of workplaces surveyed had in place a comprehensive workplace health promotion programme. However, more could still be done to encourage its uptake such as training for facilitators, consultation, grant provision etc. Small workplaces remained an untapped market for such programmes.

Objective This paper reviews coverage data from programmes treating severe acute malnutrition (SAM) collected between July 2012 and June 2013. Design This is a descriptive study of coverage levels and barriers to coverage collected by coverage assessments of community-based SAM treatment programmes in 21 countries that were supported by the Coverage Monitoring Network. Data from 44 coverage assessments are reviewed. Setting These assessments analyse malnourished populations from 6 to 59 months old to understand the accessibility and coverage of services for treatment of acute malnutrition. The majority of assessments are from sub-Saharan Africa. Results Most of the programmes (33 of 44) failed to meet context-specific internationally agreed minimum standards for coverage. The mean level of estimated coverage achieved by the programmes in this analysis was 38.3%. The most frequently reported barriers to access were lack of awareness of malnutrition, lack of awareness of the programme, high opportunity costs, inter-programme interface problems, and previous rejection. Conclusions This study shows that coverage of CMAM is lower than previous analyses of early CTC programmes; therefore reducing programme impact. Barriers to access need to be addressed in order to start improving coverage by paying greater attention to certain activities such as community sensitisation. As barriers are interconnected focusing on specific activities, such as decentralising services to satellite sites, is likely to increase significantly utilisation of nutrition services. Programmes need to ensure that barriers are continuously monitored to ensure timely removal and increased coverage. PMID:26042827

The Global Fund to Fight AIDS, Tuberculosis and Malaria has played an important role in financing the response to HIV/AIDS and tuberculosis (TB) in Indonesia. As part of a series of case studies, we assessed the nature and extent of integration of Global Fund portfolios into the national HIV and TB programmes, integration of the HIV and TB programmes within the general health system, and system-wide effects of Global Fund support on the health care system in Indonesia. The study relied on a literature review and interviews with 22 key informants using the Systemic Rapid Assessment Toolkit and thematic analysis. Global Fund programmes in Indonesia are highly vertical and centralized, in contrast with the decentralized nature of the Indonesian health system. Consequently, there is more integration of all functions at local levels than centrally. There is a high level of integration of planning of Global Fund HIV and TB portfolios into the National AIDS and TB programmes and some limited integration of these programmes with other disease programmes, through joint working groups. Other synergies include strengthening of stewardship and governance and increased staff recruitment encouraged by incentive payments and training. Monitoring and evaluation functions of the Global Fund programmes are not integrated with the disease programmes, with parallel indicators and reporting systems. System-wide effects include greater awareness of governance and stewardship in response to the temporary suspension of Global Fund funding in 2008, and increased awareness of the need to integrate programme planning, financing and service delivery. Global Fund investment has freed up resources for other programmes, particularly at local levels. However, this may hinder a robust exit strategy from Global Fund funding. Furthermore, Global Fund monetary incentives may result in staff shifting into HIV and TB programmes.

The lack of dementia education programmes for health professionals in primary care is one of the major factors contributing to the unmet demand for dementia care services. To determine the effectiveness of a nurse-led dementia education and knowledge translation programme for health professionals in primary care; participants' satisfaction with the programme; and to understand participants' perceptions of and experiences in the programme. A cluster randomized controlled trial was used as the main methodology to evaluate health professionals' knowledge, attitudes and care approach. Focus groups were used at the end of the project to understand health professionals' perceptions of and experiences in the programme. Fourteen community health service centres in a province in China participated in the study. Seven centres were randomly assigned to the intervention or control group respectively and 85 health professionals in each group completed the programme. A train-the-trainer model was used to implement a dementia education and knowledge translation programme. Outcome variables were measured at baseline, on the completion of the programme and at 3-month follow-up. A mixed effect linear regression model was applied to compare the significant differences of outcome measures over time between the two groups. Focus groups were guided by four semi-structured questions and analysed using content analysis. Findings revealed significant effects of the education and knowledge translation programme on participants' knowledge, attitudes and a person-centred care approach. Focus groups confirmed that the programme had a positive impact on dementia care practice. A dementia education and knowledge translation programme for health professionals in primary care has positive effects on their knowledge, attitudes, care approach and care practice.

2011-03-01

This paper is a report of an evaluation of the effects of a transformational leadership training programme on Unit Charge Nurses' leadership practices. Current healthcare regulations in the European Union and accreditation efforts of hospitals for their services mandate transformation in healthcare services in Turkey. Therefore, the transformational leadership role of nurse managers is vital in determining and achieving long-term goals in this process. The sample consisted of 30 Unit Charge Nurses with a baccalaureate degree and 151 observers at two university hospitals in Turkey. Data were collected using the Leadership Practices Inventory-Self and Observer (applied four times during a 14-month study process from December 2005 to January 2007). The transformational leadership training programme had theoretical (14 hours) and individual study (14 hours) in five sections. Means, standard deviations and percentages, repeated measure tests and two-way factor analysis were used for analysis. According the Leadership Practices Inventory-Self and Observer ratings, leadership practices increased statistically significantly with the implementation of the programme. There were no significant differences between groups in age, length of time in current job and current position. The Unit Charge Nurses Leadership Practices Inventory self-ratings were significantly higher than those of the observers. There is a need to develop similar programmes to improve the leadership skills of Unit Charge Nurses, and to make it mandatory for nurses assigned to positions of Unit Charge Nurse to attend this kind of leadership programme. © 2010 Blackwell Publishing Ltd.

To assess the impact of the Avahan HIV prevention programme for female sex workers (FSWs) in south India on reducing syphilis prevalence among their clients, by comparing rates of syphilis over time as reported in two large-scale surveys of FSWs' clients. A random-effect multilevel logistic regression analysis was performed using syphilis as the dependent variable, with individual independent variables (from the two survey rounds) at level 1 and the district-level programme (from the Avahan computerised monitoring and information system) and contextual variables (from Indian government datasets) at level 2. Programme variables included their 2006 value and their difference in value between 2008 and 2006, as well as the interaction between the latter and the study round. The analysis also controlled for baseline syphilis prevalence and its interaction with the study round. Syphilis decreased significantly among FSWs' clients, from 4.8% (round 1) to 2.6% (round 2), p<0.001. The OR of the interaction term between the difference in programme coverage of FSWs and the round was 0.98 (p=0.023), suggesting that increased coverage was associated with a reduced incidence of syphilis. This study suggests that the Avahan intervention programme among FSWs reduced syphilis rates among their clients. Published by the BMJ Publishing Group Limited.

Green, Anita J; Holloway, David G

2005-11-01

This paper reports on an evaluation of an innovative education and training programme for nurses and narcologists in St. Petersburg, Russia. The aims of the evaluation were: first, to evaluate the effect of the education and training programme on the clinical practice of doctors and nurses who have had direct contact with the programme and, second, to evaluate the influence of the education and training programme on city-wide drug and alcohol policy and practice. Brief contextual information regarding the programme is provided prior to an account of the qualitative methodology. Particular attention was paid to the work of Patton [Utilisation-focused evaluation, second ed., Sage, London, 1986; Qualitative research and evaluation methods, third ed., Sage, London, 2002] for the theoretical framework and to Hantais and Mangen [Cross-national research methods in the social sciences, Pinter, London, 1996] regarding the methodological issues that surround international and cross-cultural research projects. Data collection was carried out in St. Petersburg and in the United Kingdom, which involved key participants in the programme. The data analysis followed Miles and Huberman [Qualitative data analysis. An expanded sourcebook, second ed. Sage, Thousand Oaks, 1994] which yielded six major themes: rehabilitation, the role and continuing professional development of the trained nurse; the status of the nurse training-college and the staff, small scale projects and their significance; sharing experiences/networking/face-to-face meetings; and, lack of resistance. The findings are discussed and recommendations for further involvement are identified.

Quantum Stat Mech in a Programmable Spin Chain of Trapped Ions

Monroe, Christopher

2017-04-01

Trapped atomic ions are a versatile and very clean platform for the quantum programming of interacting spin models and the study of quantum nonequilibrium phenomena. When spin-dependent optical dipole forces are applied to a collection of trapped ions, an effective long-range quantum magnetic interaction arises, with reconfigurable and tunable graphs. Following earlier work on many-body spectroscopy and quench dynamics, we have recently studied many body non-thermalization processes in this system. Frustrated Hamiltonian dynamics can lead to prethermalization, and by adding programmable disorder between the sites, we have observed the phenomenon of many body localization (MBL). Finally, by applying a periodically driven Floquet Hamiltonian tempered by MBL, we report the observation of a discrete ``time crystal'' in the stable appearance of a subharmonic response of the system to the periodic drive.

Design and Development of High Voltage Direct Current (DC) Sources for the Solar Array Module Plasma Interaction Experiment

NASA Technical Reports Server (NTRS)

Bibyk, Irene K.; Wald, Lawrence W.

1995-01-01

Two programmable, high voltage DC power supplies were developed as part of the flight electronics for the Solar Array Module Plasma Interaction Experiment (SAMPIE). SAMPIE's primary objectives were to study and characterize the high voltage arcing and parasitic current losses of various solar cells and metal samples within the space plasma of low earth orbit (LEO). High voltage arcing can cause large discontinuous changes in spacecraft potential which lead to damage of the power system materials and significant Electromagnetic Interference (EMI). Parasitic currents cause a change in floating potential which lead to reduced power efficiency. These primary SAMPIE objectives were accomplished by applying artificial biases across test samples over a voltage range from -600 VDC to +300 VDC. This paper chronicles the design, final development, and test of the two programmable high voltage sources for SAMPIE. The technical challenges to the design for these power supplies included vacuum, space plasma effects, thermal protection, Shuttle vibrations and accelerations.

Programmable temperature control system for biological materials

1982-01-01

A system was constructed which allows programmable temperature-time control for a 5 cu cm sample volume of arbitrary biological material. The system also measures the parameters necessary for the determination of the sample volume specific heat and thermal conductivity as a function of temperature, and provides a detailed measurement of the temperature during phase change and a means of calculating the heat of the phase change. Steady-state and dynamic temperature control is obtained by supplying heat to the sample volume through resistive elements constructed as an integral part of the sample container. For cooling purposes, this container is totally immersed into a cold heat sink. Using a mixture of dry ice and alcohol at 79 C, the sample volume can be controlled from +40 to -60 C at rates from steady state to + or - 65 C/min. Steady-state temperature precision is better than 0.2 C, while the dynamic capability depends on the temperature rate of change as well as the mass of both the sample and the container.

To establish adolescents' beliefs regarding the need for structured diabetes education and their views on how such a programme should be organised and what topics need to be addressed. Structured diabetes education programmes have become common place in diabetes care in recent years. Despite the use of these programmes in adult patients, to date, there exists no tried or tested programme for adolescents. Prior to the development of programmes for this age group, there is a need to establish their views on programme content, delivery mechanisms and how best to introduce structured education in this population. An exploratory qualitative study. Five focus group interviews were undertaken across three acute Hospital Trusts in Northern Ireland. A total of 21 adolescents between 13-19 years were interviewed. Data were analysed by means of a thematic content analysis framework. All participants expressed a need for a structured education programme specifically tailored to their needs. The complexity of existing diabetes regimens brought with it feelings of frustration and guilt for the majority of adolescents. Many felt isolated and alone. Dietary management and insulin adjustment were seen as very complex. Participants favoured a structured diabetes education programme that was short in duration, practical in nature, positive in outlook and relevant to daily life. Relevance to clinical practice.  Programmes should address the specific needs of adolescents, be delivered in a practical manner and be realistic for everyday use. © 2011 Blackwell Publishing Ltd.

Outreach programmes to attract girls into computing: how the best laid plans can sometimes fail

This article presents a reflective analysis of an outreach programme called the Digital Divas Club. This curriculum-based programme was delivered in Australian schools with the aim of stimulating junior and middle school girls' interest in computing courses and careers. We believed that we had developed a strong intervention programme based on previous literature and our collective knowledge and experiences. While it was coordinated by university academics, the programme content was jointly created and modified by practicing school teachers. After four years, when the final data were compiled, it showed that our programme produced significant change to student confidence in computing, but the ability to influence a desire to pursue a career path in computing did not fully eventuate. To gain a deeper insight in to why this may be the case, data collected from two of the schools are interrogated in more detail as described in this article. These schools were at the end of the expected programme outcomes. We found that despite designing a programme that delivered a multi-layered positive computing experience, factors beyond our control such as school culture and teacher technical self-efficacy help account for the unanticipated results. Despite our best laid plans, the expectations that this semester long programme would influence students' longer term career outcomes may have been aspirational at best.

Universal alcohol misuse prevention programmes for children and adolescents: Cochrane systematic reviews.

Foxcroft, David R; Tsertsvadze, Alexander

2012-05-01

Alcohol misuse by young people causes significant health and social harm, including death and disability. Therefore, prevention of youth alcohol misuse is a policy aim in many countries. Our aim was to examine the effectiveness of (1) school-based, (2) family-based and (3) multi-component universal alcohol misuse prevention programmes in children and adolescents. Three Cochrane systematic reviews were performed: searches in MEDLINE, EMBASE, PsycINFO, Project CORK and the Cochrane Register of Controlled Trials up to July 2010, including randomised trials evaluating universal alcohol misuse prevention programmes in school, family or multiple settings in youths aged 18 years or younger. Two independent reviewers identified eligible studies and any discrepancies were resolved via discussion. A total of 85 trials were included in the reviews of school (n = 53), family (n = 12) and multi-component (n = 20) programmes. Meta-analysis was not performed due to study heterogeneity. Most studies were conducted in North America. Risk of bias assessment revealed problems related to inappropriate unit of analysis, moderate to high attrition, selective outcome reporting and potential confounding. Certain generic psychosocial and life skills school-based programmes were effective in reducing alcohol use in youth. Most family-based programmes were effective. There was insufficient evidence to conclude that multiple interventions provided additional benefit over single interventions. In these Cochrane reviews, some school, family or multi-component prevention programmes were shown to be effective in reducing alcohol misuse in youths. However, these results warrant a cautious interpretation, since bias and/or contextual factors may have affected the trial results. Further research should replicate the most promising studies identified in these reviews and pay particular attention to content and context factors through rigorous evaluation.

Programmable liquid crystal waveplate polarization gratings as elements for polarimetric and interference applications

NASA Astrophysics Data System (ADS)

Moreno, I.; Davis, J. A.

2010-06-01

We review the use of a parallel aligned nematic liquid crystal spatial light modulator as a very useful and flexible device for polarimetric and interferometric applications. The device acts as a programmable pixelated waveplate, and the encoding of a linear grating permits its use as a polarization beam splitter. When a grating with a reduced period is encoded, the diffracted beams are spatially separated and the device can be used for polarimetric analysis. On the contrary when a large period grating is displayed, the beams are not spatially separated, and they are useful to realize a common path interferometric system with polarization sensitivity. The flexibility offered by the programmability of the display allows non-conventional uses, including the analysis of light beams with structured spatial polarizations.

Neumann, Jan; Robson, Andrew; Sloan, Diane

2018-02-01

This study considered the monitoring and evaluation of a large-scale and domestic and global strategic change programme implementation. It considers the necessary prerequisites to overcome challenges and barriers that prevent systematic and effective monitoring and evaluation to take place alongside its operationalisation. The work involves a case study based on a major industrial company from the energy sector. The change programme makes particular reference to changes in business models, business processes, organisation structures as well as Enterprise Resource Planning infrastructure. The case study focussed on the summative evaluation of the programme post-implementation. This assessment involved 25 semi-structured interviews with employees across a range of managerial strata capturing more than 65 roles within the change programme at both local and global levels. Data relating to their perception of evaluation effectiveness and shortcomings were analysed by means of template analysis. The study identifies responsibilities for executing an evaluation alongside various methods and tools that are appropriate, thereby focussing on the "Who" (roles, responsibility for particular activities) and "How" (methods and tools) rather than "What" to monitor and evaluate. The findings are presented generically so they offer new insights and transferability for practitioners involved in managing strategic change and its associated evaluation.

How to use programme theory to evaluate the effectiveness of schemes designed to improve the work environment in small businesses.

PubMed

Olsen, Kirsten; Legg, Stephen; Hasle, Peter

2012-01-01

Due to the many constraints that small businesses (SBs) face in meeting legislative requirements, occupational health and safety (OHS) regulatory authorities and other OSH actors have developed programmes which can reach out to SBs and motivate and assist them in improving the work environment. A number of conceptual models help to enhance our understanding of OHS interventions in SBs and their effectiveness. However, they have mainly been evaluated on output rather than the process relating to the change theory underlying the intervention, and hence have seldom been rigorously evaluated. Thus little is known about how particular features of SBs can be taken into account when designing and implementing national programmes. This paper shows how realist analysis and programme theory may be used as a framework for evaluating, developing and improving national intervention programmes for the improvement of the work environment and reducing injuries in SBs. It illustrates this for a specific New Zealand intervention: the Workplace Safety Discount scheme and its implementation in the agriculture sector. In practice, realist analysis should be performed during the planning, implementation and management stages so that ongoing findings can be fed back to the participant social actors to help them make appropriate changes to enhance the likelihood of success.

We undertook a qualitative analysis to identify the broader benefits of a state-wide acute stroke telemedicine service beyond the patient-clinician consultation. Since 2010, the Victorian Stroke Telemedicine (VST) programme has provided a clinical service for regional hospitals in Victoria, Australia. The benefits of the Victorian Stroke Telemedicine programme were identified through document analysis of governance activities, including communications logs and reports from hospital co-ordinators of the programme. Discussions with the Victorian Stroke Telemedicine management were undertaken and field notes were also reviewed. Several benefits of telemedicine were identified within and across participating hospitals, as well as for the state government and community. For hospitals, standardisation of clinical processes was reported, including improved stroke care co-ordination. Capacity building occurred through professional development and educational workshops. Enhanced networking, and resource sharing across hospitals was achieved between hospitals and organisations. Governments leveraged the Victorian Stroke Telemedicine programme infrastructure to provide immediate access to new treatments for acute stroke care in regional areas. Standardised data collection allowed routine quality of care monitoring. Community awareness of stroke symptoms occurred with media reports on the novel technology and improved patient outcomes. The value of telemedicine services extends beyond those involved in the clinical consultation to healthcare funders and the community. © The Author(s) 2016.

This work analyses the short-term physiological and neurophysiological effects of a brisk walking programme in ageing, healthy, active men. Twenty-one men 63 to 72 years of age were recruited and separated into 2 groups. One group performed a walking programme (WP) (n = 11) and another served as control (C) group (n = 10). The walking programme lasted for twelve weeks and included five sessions per week. Several parameters were assessed before and after the programme for the WP group. The same tests were performed (separated by twelve weeks) in group C. During each assessment, the subjects were put through static and dynamic balance tests, spatio-temporal gait analysis, body composition measurements and determination of aerobic capacity and bone mineral density. The statistic analysis showed a significant improvement in dynamic balance performance, especially in lateral sway when the subjects kept their eyes open, an increase of VO(2) max and loss of fat mass in the WP group. However, no alterations appeared in spatiotemporal gait characteristics, static balance performance, lean mass or bone mineral density (total body and hip). According to these results, this walking programme may have positive effects on preventing ageing subjects from falling.

The analysis and simulation of complex interacting biochemical reaction pathways in cells is important in all of systems biology and medicine. Yet, the dynamics of even a modest number of noisy or stochastic coupled biochemical reactions is extremely time consuming to simulate. In large part, this is because of the expensive cost of random number and Poisson process generation and the presence of stiff, coupled, nonlinear differential equations. Here, we demonstrate that we can amplify inherent thermal noise in chips to emulate randomness physically, thus alleviating these costs significantly. Concurrently, molecular flux in thermodynamic biochemical reactions maps to thermodynamic electronic current in a transistor such that stiff nonlinear biochemical differential equations are emulated exactly in compact, digitally programmable, highly parallel analog "cytomorphic" transistor circuits. For even small-scale systems involving just 80 stochastic reactions, our 0.35-μm BiCMOS chips yield a 311× speedup in the simulation time of Gillespie's stochastic algorithm over COPASI, a fast biochemical-reaction software simulator that is widely used in computational biology; they yield a 15 500× speedup over equivalent MATLAB stochastic simulations. The chip emulation results are consistent with these software simulations over a large range of signal-to-noise ratios. Most importantly, our physical emulation of Poisson chemical dynamics does not involve any inherently sequential processes and updates such that, unlike prior exact simulation approaches, they are parallelizable, asynchronous, and enable even more speedup for larger-size networks.

The physical bases of the detection and characterisation of extrasolar Earth-like planets and moons in the reflected light and thermal emission regimes are reviewed. They both have their advantages and disadvantages, including artefacts, in the determination of planet physical parameters (mass, size, albedo, surface and atmospheric conditions etc.). After a short panorama of detection methods and the first findings, new perspectives for these different aspects are also presented. Finally brief account of the ground based programmes and space-based projects and their potentialities for Earth-like planets is made and discussed.

Incorporating a state-of-the-art process control and instrumentation system into a complex system for thermal vacuum testing is discussed. The challenge was to connect several independent control systems provided by various vendors to a supervisory computer. This combination will sequentially control and monitor the process, collect the data, and transmit it to color a graphic system for subsequent manipulation. The vacuum system upgrade included: replacement of seventeen diffusion pumps with eight cryogenic pumps and one turbomolecular pump, replacing a relay based control system, replacing vacuum instrumentation, and upgrading the data acquisition system.

The need for mechanical manipulation during the curing of conventional liquid crystal elastomers diminishes their applicability in the field of shape-programmable soft materials and future applications in additive manufacturing. Here we report on polymer-dispersed liquid crystal elastomers, novel composite materials that eliminate this difficulty. Their thermal shape memory anisotropy is imprinted by curing in external magnetic field, providing for conventional moulding of macroscopically sized soft, thermomechanically active elastic objects of general shapes. The binary soft-soft composition of isotropic elastomer matrix, filled with freeze-fracture-fabricated, oriented liquid crystal elastomer microparticles as colloidal inclusions, allows for fine-tuning of thermal morphing behaviour. This is accomplished by adjusting the concentration, spatial distribution and orientation of microparticles or using blends of microparticles with different thermomechanical characteristics. We demonstrate that any Gaussian thermomechanical deformation mode (bend, cup, saddle, left and right twist) of a planar sample, as well as beat-like actuation, is attainable with bilayer microparticle configurations.

ITER first wall (FW) panels are irradiated by energetic neutrons during the nuclear phase. Thus, an irradiation and high heat flux testing programme is undertaken by the ITER organization in order to evaluate the effects of neutron irradiation on the performance of enhanced heat flux (EHF) FW components. The test campaign includes neutron irradiation (up to 0.6-0.8 dpa at 200 °C-250 °C) of mock-ups that are representative of the final EHF FW panel design, followed by thermal fatigue tests (up to 4.7 MW m-2). Mock-ups were manufactured by the same manufacturing process as proposed for the series production. After a pre-irradiation thermal screening, eight mock-ups will be selected for the irradiation campaigns. This paper reports the preparatory work of HHF tests and neutron irradiation, assessment results as well as a brief description of mock-up manufacturing and inspection routes.

There is a high incidence of concussion sustained by athletes participating in rugby union, many of which go unreported. A lack of sufficient knowledge about concussion injuries may explain athletes' failure to report. Several rugby union-playing countries have developed injury education and prevention programmes to address this issue. The aim of the current review was to systematically assess the content and level of evidence on concussion education/prevention programmes in rugby union and to make recommendations for the quality, strength, and consistency of this evidence. We searched PubMed, PsycInfo, MEDLINE, SPORTDiscuss, Webofscience, and conducted a manual search for articles. Ten articles were included for review. Of these, six focused on the BokSmart injury prevention programme in South Africa, two focused on the RugbySmart injury prevention programme in New Zealand, one was an analysis of prevention programmes, and one was a systematic review of rugby injury prevention strategies. Despite the initiative to develop concussion education and prevention programmes, there is little evidence to support the effectiveness of such programmes. There is evidence to support education of coaches and referees. In addition, there is scant evidence to suggest that education and rule changes may have the benefit of changing athlete behaviours resulting in a reduction in catastrophic injury.

To identify the most common and most valued outcomes of community-based rehabilitation (CBR) in Chinese communities and to map these to the CBR evaluation framework. A multiple, embedded case study design was used. Four CBR programmes in China met the criteria for inclusion and participated. Data collection, via participant "story telling", followed the procedures of the most significant change technique (MSC) over a period for five months. Content analysis with thematic coding was used to detect the common significant changes described in "top-rated" stories and in the entire pool of stories. Meta-analysis using the CBR framework was carried out to enrich the understanding of programme outcomes. A total of 101 stories were collected in the two rounds of story collection from the four programmes. Aggregated results demonstrated that, across all programmes, 78.21% of stories focused on changes in people with disabilities, 9.9% described aspects of programme development, 8.91% reported on outcomes related to CBR workers, and only 2.97% were focused on advocacy. When mapped against the elements of the CBR framework the MSCs among these four programmes were (1) psychosocial changes, (2) increased family participation and (3) improved physical functioning. CBR practice in Chinese communities remains orientated towards an approach of functional rehabilitation rather than community-based inclusive development. Implications for rehabilitation Community-based rehabilitation is a strategy for community-based inclusive development. Commonly reported significant outcomes of community-based rehabilitation programmes in China focus on changes in psychosocial and physical status of people with disabilities and family participation. Community-based rehabilitation in China continues to focus on traditional rehabilitation. New efforts and directions are needed to also include goals of equity and community inclusion. Further efforts to promote the use of CBR guideline with the goal of facilitating inclusion and equal participation are strongly recommended.

Progress towards reducing mortality and malnutrition among children <5 years of age has been less than needed to achieve related Millennium Development Goals (MDGs), so several international agencies joined to 'reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The main objectives of the situational analysis are to compile, analyse, and interpret available information on infant and child feeding, and the nutrition and health situation of children <2 years of age in Mauritania as one of the six target countries (Burkina Faso, Chad, Mali, Mauritania, Niger, Senegal). These findings are available to assist countries in identifying inconsistencies and filling gaps in current programming. Between August and November of 2008, key informants responsible for conducting IYCN-related activities in Mauritania were interviewed, and 46 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, prevention of mother-to-child transmission of human immunodeficiency virus (HIV), management of acute malnutrition, food security, and hygienic practices. Mauritania is on track to reaching the MDG of halving undernutrition among children <5 years of age by 2015. National policy documents, training guides, and programmes address nearly all of the key IYCN topics, specifically or generally. Exceptions are the use of zinc supplements in diarrhoea treatment, prevention of zinc deficiency, and dietary guidelines for preventing mother-to-child transmission of HIV. Substantial infrastructure capacity building was also recently implemented in nutritionally high-risk regions, and increases were reported in exclusive breastfeeding rates among children <6 months. The recent National Behaviour Change Communication Strategy is intended to address the needs of adapting programme activities to local needs. Despite these noteworthy accomplishments, the prevalence of acute malnutrition remains high, mortality rates did not decrease as malnutrition rates decreased, the overall prevalence of desirable nutrition-related practices is low, and human resources are reportedly insufficient to carry out all nutrition-related programme activities. Very little nutrition research has been conducted in Mauritania, and key informants identified gaps in adapting international programmes to local needs. Monitoring and evaluation reports have not been rigorous enough to identify which programme activities were implemented as designed or whether programmes were effective at improving nutritional and health status of young children. Therefore, we could not confirm which programmes might have been responsible for the reported improvements, or if other population-wide changes contributed to these changes. The policy framework is supportive of optimal IYCN practices, but greater resources and capacity building are needed to (i) support activities to adapt training materials and programme protocols to fit local needs, (ii) expand and track the implementation of evidence-based programmes nationally, (iii) improve and carry out monitoring and evaluation that identify effective and ineffective programmes, and (iv) apply these findings in developing, disseminating, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

The Inter-Health Programme was launched in 1986 by WHO, with the collaboration of a coordination centre (National Public Health Institute, Finland) to control and prevent chronic noncommunicable diseases (CNCDs) among adults. Programmes for action were organized based on the concept that most major CNCDs share common risk factors and that those that are lifestyle related are modifiable through efficient interventions using multifactorial strategies involving community participation and behaviour changes carried out at the primary health care level. Twelve countries from all WHO Regions have joined the programme. A baseline survey was undertaken in all countries with a common protocol, following the criteria and methods employed in the MONICA Project. Altogether 36815 men and women aged 35-64 years were included in the present analysis from the following Inter-Health countries: Chile, China, Cyprus, Finland, Lithuanian SSR, Malta, Mauritius, Russian SFSR, United Republic of Tanzania, and USA. In addition to individual country analysis, centralized analysis was carried out at the Finnish National Public Health Institute and the Department of Community Health, Kuopio University, Finland. Reported here are the mean values of blood pressure, body mass index, and serum total cholesterol as well as specific prevalences of smoking, hypertension, obesity, and hypercholesterolaemia.

In the light of increasing childhood obesity, the role of food advertisements relayed on television (TV) is of high interest. There is evidence of food commercials having an impact on children's food preferences, choices, consumption and obesity. We describe the product categories advertised during kids programmes, the type of food promoted and the characteristics of food commercials targeting children. A content analysis of the commercials aired during the kids programmes of six Swiss, one German and one Italian stations was conducted. The commercials were collected over a 6-month period in 2006. Overall, 1365 h of kids programme were recorded and 11 613 advertisements were found: 3061 commercials (26.4%) for food, 2696 (23.3%) promoting toys, followed by those of media, cleaning products and cosmetics. Regarding the broadcast food advertisements, 55% were for fast food restaurants or candies. The results of the content analysis suggest that food advertising contributes to the obesity problem: every fourth advertisement is for food, half of them for products high in sugar and fat and hardly any for fruit or vegetables. Long-term exposure to this distortion of the pyramid of recommended food should be considered in the discussion of legal restrictions for food advertising targeting children.

In 1966, nineteen countries of West and Central Africa began a regional smallpox eradication and measles control programme in cooperation with the World Health Organization. This paper summarizes sample survey data collected to assess the results of the programme in Northern Nigeria (Sokoto and Katsina Provinces), Western Nigeria, Niger, Dahomey, and Togo. These data indicate that the programme, which used mass vaccination campaigns based on a collecting-point strategy, was generally successful in reaching a high proportion of the population. Analysis of vaccination coverage and vaccination scar rates by age underlined the importance to the programme of newborn children who accumulate rapidly following the mass campaign. Of all persons without vaccination scars at the time of the surveys, 34.4% were under 5 years of age; in the absence of a maintenance programme, this figure would rise to 40% after 1 year.

The Universal Newborn Hearing Screening (UNHS) programme aims at achieving early detection of hearing impairment. Subsequent diagnosis and intervention should follow promptly. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for early Identification, Intervention and Care of Hearing Impaired Children", the limitations and strengths of current UNHS programs in Italy have been analysed by a group of professionals working in tertiary centres involved in regional UNHS programmes, using SWOT analysis and a subsequent TOWS matrix. Coverage and lost-to-follow up rates are issues related to UNHS programmes. Recommendations to improve the effectiveness of the UNHS programme have been identified. The need for homogeneous policies, high-quality information and dissemination of knowledge for operators and families of hearing-impaired children emerged from the discussion. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

Cultural adaptation of evidence-based programmes has gained importance primarily owing to its perceived impact on the established effectiveness of a programme. To date, many researchers have proposed different frameworks for systematic adaptation process. This article presents the cultural adaptation of preschool Promoting Alternative Thinking Strategies (PATHS) curriculum for Pakistani children using the heuristic framework of adaptation (Barrera & Castro, 2006). The study was completed in four steps: information gathering, preliminary adaptation design, preliminary adaptation test and adaptation refinement. Feedbacks on programme content suggested universality of the core programme components. Suggested changes were mostly surface structure: language, presentation of materials, conceptual equivalence of concepts, training needs of implementation staff and frequency of programme delivery. In-depth analysis was done to acquire cultural equivalence. Pilot testing of the outcome measures showed strong internal consistency. The results were further discussed with reference to similar work undertaken in other cultures. © 2014 International Union of Psychological Science.

In 2011 an interprofessional educational programme called "Pediatric systematic assessment and communication for preventing emergencies" designed to increase clinical staff's competence in treating sick children was introduced in one paediatrics department in Norway. To elicit an in-depth understanding of the perceptions of clinical staff about the programme and enact adjustments according to identified enabling and hindering factors for learning, nurses and paediatricians were invited to participate in focus group interviews. The interviews were analysed by content analysis. Enabling factors for learning included improved interprofessional collaboration and positive feedback on performance. Hindering factors included perceptions that the programme was redundant and the fact that collaborating departments, such as the surgical departments, were not familiar with the programme. Peer learning, more interprofessional learning activities, and the fostering of a learning organization were suggestions for sustained learning. Based on the results of the study we have now included collaborating departments in the programme.

A cryogenic test article, the Generic Research Cryogenic Tank, was designed to qualitatively simulate the thermal response of transatmospheric vehicle fuel tanks exposed to the environment of hypersonic flight. One-dimensional and two-dimensional finite-difference thermal models were developed to simulate the thermal response and assist in the design of the Generic Research Cryogenic Tank. The one-dimensional thermal analysis determined the required insulation thickness to meet the thermal design criteria and located the purge jacket to eliminate the liquefaction of air. The two-dimensional thermal analysis predicted the temperature gradients developed within the pressure-vessel wall, estimated the cryogen boiloff, and showed the effects the ullage condition has on pressure-vessel temperatures. The degree of ullage mixing, location of the applied high-temperature profile, and the purge gas influence on insulation thermal conductivity had significant effects on the thermal behavior of the Generic Research Cryogenic Tank. In addition to analysis results, a description of the Generic Research Cryogenic Tank and the role it will play in future thermal structures and transatmospheric vehicle research at the NASA Dryden Flight Research Facility is presented.

Dental caries is one of the most common diseases of childhood. The aim of this study was to compare the cost of providing the Scotland-wide nursery toothbrushing programme with associated National Health Service (NHS) cost savings from improvements in the dental health of five-year-old children: through avoided dental extractions, fillings and potential treatments for decay. Methods Estimated costs of the nursery toothbrushing programme in 2011/12 were requested from all Scottish Health Boards. Unit costs of a filled, extracted and decayed primary tooth were calculated using verifiable sources of information. Total costs associated with dental treatments were estimated for the period from 1999/00 to 2009/10. These costs were based on the unit costs above and using the data of the National Dental Inspection Programme and then extrapolated to the population level. Expected cost savings were calculated for each of the subsequent years in comparison with the 2001/02 dental treatment costs. Population standardised analysis of hypothetical cohorts of 1000 children per deprivation category was performed. Results The estimated cost of the nursery toothbrushing programme in Scotland was £1,762,621 per year. The estimated cost of dental treatments in the baseline year 2001/02 was £8,766,297, while in 2009/10 it was £4,035,200. In 2002/03 the costs of dental treatments increased by £213,380 (2.4%). In the following years the costs decreased dramatically with the estimated annual savings ranging from £1,217,255 in 2003/04 (13.9% of costs in 2001/02) to £4,731,097 in 2009/10 (54.0%). Population standardised analysis by deprivation groups showed that the largest decrease in modelled costs was for the most deprived cohort of children. Conclusions The NHS costs associated with the dental treatments for five-year-old children decreased over time. In the eighth year of the toothbrushing programme the expected savings were more than two and a half times the costs of the programme implementation. PMID:26305577

The purpose of the study was to empower rural parents to participate in the sexuality education of their children. The study was designed to be qualitative, explorative, descriptive and contextual in nature. It was performed in three phases. Phase 1 consisted of a situational analysis to explore and describe how parents provide sexuality education. Phase 2 consisted of the development of a conceptual framework that facilitated the development of an educational programme. In phase 3 the programme was implemented and evaluated, recommendations were made and conclusions drawn. The main findings revealed two themes: factors influencing parental participation in their children’s sexuality education, and the need for parental participation in their children’s sexuality education. This article is part of series of three article stems from a study on the topic of sexuality education empowerment programme of rural parents in Namibia. The three articles have the following titles one: parent’s participation in sexuality education of their children: a situational analysis; two: parent’s participation in sexuality education of their children: a conceptual framework and an educational programme to enhance action, and three: parent’s participation in sexuality education of their children: programme implementation and evaluation. The previous paper dealt with parent’s participation in sexuality education of their children: a situational analysis: the results from the in-depth interviews and focus group discussions on sexuality education with children and parents were presented. This paper focuses on describing Phase 2 and 3, namely the process of devising a conceptual framework for the development of an educational programme to empower parents to participate in the sexuality education of their children. Discussions included a description of the conceptual framework, based on the researcher’s paradigmatic assumptions, and the focus group and individual in-depth interviews results. The survey list suggested by Dickoff et al. (1968) consists of various elements which were employed in the conceptual framework, namely the context, agent, recipients, dynamics, procedure and a terminus. These elements were reflected in the “thinking map”. PMID:26573053

There is inadequate evidence for the effectiveness and cost-effectiveness of health promotion interventions. The Salut Programme aims to reach all parents and children in the Västerbotten County of Sweden with a combination of health promotion interventions initiated during pregnancy and continued over the childhood period. This study protocol describes an effectiveness study and an economic evaluation study, where the ongoing Salut Programme is compared to care-as-usual over the periods of pregnancy, delivery and the child's first 2 years of life. A register-based retrospective observational study design will be used with existing data sources with respect to exposures and outcomes. Outcomes of interest are clustered at 3 points: around the child's birth, 1 month after the child's birth and 2 years after the child's birth. We will simulate an experiment by retrospectively identifying and comparing children and their parents in the geographical areas where the Salut Programme was implemented since 2006 and onwards, and the areas where the Programme was not implemented before 2009. Outcomes will be analysed and compared for the premeasure period, and the postmeasure period for both groups. Our analysis combines difference-in-difference estimation with matching. A complementary analysis will be carried out on the longitudinal subsample of mothers who gave birth at least once during each of the time periods. The economic evaluation aims to capture the wider societal costs and benefits of the Salut Programme for the first 2 years of the children's lives.

The purpose of the study was to empower rural parents to participate in the sexuality education of their children. The study was designed to be qualitative, explorative, descriptive and contextual in nature. It was performed in three phases. Phase 1 consisted of a situational analysis to explore and describe how parents provide sexuality education. Phase 2 consisted of the development of a conceptual framework that facilitated the development of an educational programme. In phase 3 the programme was implemented and evaluated, recommendations were made and conclusions drawn. The main findings revealed two themes: factors influencing parental participation in their children's sexuality education, and the need for parental participation in their children's sexuality education. This article is part of series of three article stems from a study on the topic of sexuality education empowerment programme of rural parents in Namibia. The three articles have the following titles: one: parent's participation in sexuality education of their children: a situational analysis; two: parent's participation in sexuality education of their children: a conceptual framework and an educational programme to enhance action, and three: parent's participation in sexuality education of their children: programme implementation and evaluation. The previous paper dealt with parent's participation in sexuality education of their children: a situational analysis: the results from the in-depth interviews and focus group discussions on sexuality education with children and parents were presented. This paper focuses on describing Phase 2 and 3, namely the process of devising a conceptual framework for the development of an educational programme to empower parents to participate in the sexuality education of their children. Discussions included a description of the conceptual framework, based on the researcher's paradigmatic assumptions, and the focus group and individual in-depth interviews results. The survey list suggested by Dickoff et al. (1968) consists of various elements which were employed in the conceptual framework, namely the context, agent, recipients, dynamics, procedure and a terminus. These elements were reflected in the "thinking map".

Australians living in rural and remote communities experience relatively poor health status in comparison to the wider Australian population (Med J Aust 185:37-38, 2006). This can be attributed in part to issues of access to health services arising from difficulties in recruiting and retaining health professionals in these areas. The Rural Health Professionals Program is an initiative designed to increase the number of allied health and nursing professionals in rural and remote Australia by providing case managed recruitment and retention support services. This paper reports on early analysis of available programme data to build knowledge of factors related to the recruitment and distribution of health professionals in rural and remote Australia. Administrative programme data were collected monthly from 349 health professionals over the first 13 months of programme operation. These data were collated and quantitative analysis was conducted using SPSS software. Sixty-nine percent of recruits were women, and recruits had a mean age of 32.85 (SD = 10.92). Sixty percent of recruits were domestically trained, and the top two professions recruited were nurses (29%) and physiotherapists (21%). Eighty-seven percent were recruited to regional areas, with the remaining 13% recruited to remote areas. Among reasons for interest in the programme, financial support factors were most commonly cited by recruits (51%). Recruitment to a remote location was associated with being domestically trained, having previously lived in a rural or remote location, being a nurse (as opposed to an allied health professional) and older age. The findings provide early support for a case managed recruitment programme to improve distribution of health professionals, and some directions for future marketing and promotion of the programme. It is recommended that an outcome evaluation be conducted to determine the impact of the programme on recruitment and distribution outcomes. The findings herein begin to address gaps in the literature relating to the effectiveness of interventions to improve the distribution of health professionals. While this provides some preliminary indication that case managed recruitment and retention programmes have capacity to improve distribution, further research and evaluation is required to confirm the impact of the programme on retention.

The National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme supports research tailored to the needs of NHS decision-makers, patients and clinicians. This study reviewed the impact of the programme, from 2003 to 2013, on health, clinical practice, health policy, the economy and academia. It also considered how HTA could maintain and increase its impact. Interviews (n = 20): senior stakeholders from academia, policy-making organisations and the HTA programme. Bibliometric analysis: citation analysis of publications arising from HTA programme-funded research. Researchfish survey: electronic survey of all HTA grant holders. Payback case studies (n = 12): in-depth case studies of HTA programme-funded research. We make the following observations about the impact, and routes to impact, of the HTA programme: it has had an impact on patients, primarily through changes in guidelines, but also directly (e.g. changing clinical practice); it has had an impact on UK health policy, through providing high-quality scientific evidence - its close relationships with the National Institute for Health and Care Excellence (NICE) and the National Screening Committee (NSC) contributed to the observed impact on health policy, although in some instances other organisations may better facilitate impact; HTA research is used outside the UK by other HTA organisations and systematic reviewers - the programme has an impact on HTA practice internationally as a leader in HTA research methods and the funding of HTA research; the work of the programme is of high academic quality - the Health Technology Assessment journal ensures that the vast majority of HTA programme-funded research is published in full, while the HTA programme still encourages publication in other peer-reviewed journals; academics agree that the programme has played an important role in building and retaining HTA research capacity in the UK; the HTA programme has played a role in increasing the focus on effectiveness and cost-effectiveness in medicine - it has also contributed to increasingly positive attitudes towards HTA research both within the research community and the NHS; and the HTA focuses resources on research that is of value to patients and the UK NHS, which would not otherwise be funded (e.g. where there is no commercial incentive to undertake research). The programme should consider the following to maintain and increase its impact: providing targeted support for dissemination, focusing resources when important results are unlikely to be implemented by other stakeholders, particularly when findings challenge vested interests; maintaining close relationships with NICE and the NSC, but also considering other potential users of HTA research; maintaining flexibility and good relationships with researchers, giving particular consideration to the Technology Assessment Report (TAR) programme and the potential for learning between TAR centres; maintaining the academic quality of the work and the focus on NHS need; considering funding research on the short-term costs of the implementation of new health technologies; improving the monitoring and evaluation of whether or not patient and public involvement influences research; improve the transparency of the priority-setting process; and continuing to monitor the impact and value of the programme to inform its future scientific and administrative development.

Harm reduction programmes in the Asia--Pacific Region.

Reid, Gary; Devaney, Madonna L; Baldwin, Simon

2008-01-01

This paper reports on the public health intervention of harm reduction to address drug use issues in the Asia-Pacific region. It is based on the report 'Situational analysis of illicit drug issues and responses in Asia and the Pacific', commissioned by the Australian National Council on Drugs Asia Pacific Drug Issues Committee. A comprehensive desk-based review based on published and unpublished literature and key informant data. Drug use in the Asia--Pacific region is widespread, resulting in serious adverse health consequences. Needle and syringe programmes are found in some parts of Asia, but not in the six Pacific Island countries reviewed. Outreach and peer education programmes are implemented, but overall appear minor in size and scope. Substitution therapy programmes appear to be entering a new era of acceptance in some parts of Asia. Primary health care specifically for drug users overall is limited. Harm reduction programmes in the Asia--Pacific region are either small in scale or do not exist. Most programmes lack the technical capacity, human resources and a limited scope of operations to respond effectively to the needs of drug users. Governments in this region should be encouraged to endorse evidence-based harm reduction programmes.

There is a need for effective prevention programmes aimed at reducing risk behaviour among South African adolescents. HealthWise South Africa is a school-based programme designed to reduce sexual and substance use risk behaviour, and promote positive use of leisure time among high-school learners (students). Based on successful programmes in the United States of America, HealthWise was developed for use in South Africa and pilot tested in four South African high schools. We carried out a process evaluation to establish the fidelity of implementation and make sure HealthWise was culturally relevant. Data sources comprised focus groups with educators and learners, lesson evaluations and observations, and interviews with school principals. Qualitative analysis of data highlighted pertinent cultural and contextual factors and identified areas for modifying HealthWise in order to promote better programme-consumer fit. These areas centred on time, language, and leisure. We noted a dynamic tension between the educators' desire to adhere to plan, and to make adaptations in accordance with learners' needs and the context. Ultimately, researchers need to find a balance between fidelity of implementation and programme adaptation to obtain effective programmes that are culturally acceptable to local consumers.

The Redesigning Daily Occupations programme (ReDO) is a Swedish work rehabilitation programme for women on sick leave due to stress-related disorders. The aim of the study was to investigate the participants' perceptions of taking part in the work rehabilitation programme. Seven of the 38 women who completed ReDO were interviewed during and after the programme. The interviews were analysed by manifest and latent content analysis. The informants were satisfied with the content of the programme and the support they received in the programme and when returning to work. The women thought they had become more aware of what they did during a day and how they performed their daily activities, which helped them to change their ways of performing them. The result highlighted different parts of their rehabilitation process which constituted four sub-themes: "Perceptions of the ReDO", "The intrinsic process", "Person-related changes", and "Perceptions of returning to work", and formed the core theme "Critical parts of the rehabilitation process". The findings may not be generalized to other settings and future research should further investigate work rehabilitation for the target group.

Final Report A Multi-Language Environment For Programmable Code Optimization and Empirical Tuning

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

Yi, Qing; Whaley, Richard Clint; Qasem, Apan

This report summarizes our effort and results of building an integrated optimization environment to effectively combine the programmable control and the empirical tuning of source-to-source compiler optimizations within the framework of multiple existing languages, specifically C, C++, and Fortran. The environment contains two main components: the ROSE analysis engine, which is based on the ROSE C/C++/Fortran2003 source-to-source compiler developed by Co-PI Dr.Quinlan et. al at DOE/LLNL, and the POET transformation engine, which is based on an interpreted program transformation language developed by Dr. Yi at University of Texas at San Antonio (UTSA). The ROSE analysis engine performs advanced compiler analysis,more » identifies profitable code transformations, and then produces output in POET, a language designed to provide programmable control of compiler optimizations to application developers and to support the parameterization of architecture-sensitive optimizations so that their configurations can be empirically tuned later. This POET output can then be ported to different machines together with the user application, where a POET-based search engine empirically reconfigures the parameterized optimizations until satisfactory performance is found. Computational specialists can write POET scripts to directly control the optimization of their code. Application developers can interact with ROSE to obtain optimization feedback as well as provide domain-specific knowledge and high-level optimization strategies. The optimization environment is expected to support different levels of automation and programmer intervention, from fully-automated tuning to semi-automated development and to manual programmable control.« less

Study of Selected Composites Copper Concentrate-Plastic Waste Using Thermal Analysis

NASA Astrophysics Data System (ADS)

Szyszka, Danuta

2017-12-01

The paper presents thermal analysis of selected composites (copper concentrate, plastic waste) in two stages. The first stage consisted in thermogravimetric analysis and differential thermal analysis on the applied plastic waste and copper concentrate, and subsequently, a comparative study has been carried out on products obtained, constituting composites of those materials. As a result of analyses, it was found that up to ca. 400 °C composites show high thermal stability, whereas above that temperature, a thermal decomposition of the composite occurs, resulting in emissions of organic compounds, i.e. hydrocarbon compounds and organic oxygenate derivatives.

Case management allows us to respond to the complex needs of a vulnerable clientele through a structured approach that promotes enhanced interaction between partners. Syntheses on the subject converge towards a need for a better description of the relationships between programmes and their local context, as well as the characteristics of the clienteles and programmes that contribute to positive impacts. The purpose of this project is thus to describe and evaluate the case management programmes of four health and social services centres in the Saguenay-Lac- Saint-Jean region of Québec, Canada, in order to inform their improvement while creating knowledge on case management that can be useful in other contexts. This research relies on a multiple embedded case study design based on a developmental evaluation approach. We will work with the case management programme for high users of hospital services of each centre. Three different units of analysis will be interwoven to obtain an in-depth understanding of each case, that is: (1) health and social services centre and local services network, (2) case management programme and (3) patients who are high users of services. Two strategies for programme evaluation (logic models and implementation analysis) will guide the mixed data collection based on qualitative and quantitative methods. This data collection will rely on: (1) individual interviews and focus groups; (2) participant observation; (3) document analysis; (4) clinical and administrative data and (5) questionnaires. Description and comparison of cases, and integration of qualitative and quantitative data will be used to guide the data analysis. The study protocol was approved by the Ethics Research Boards of the four health and social services centres (HSSCs) involved. Findings will be disseminated by publications in peer-reviewed journals, conferences, and policy and practice partners in local and national government. Published by the BMJ Publishing Group Limited.

The knowledge generated from evidence-based interventions in mental health systems research is seldom translated into policy and practice in low and middle-income countries (LMIC). Stakeholder analysis is a potentially useful tool in health policy and systems research to improve understanding of policy stakeholders and increase the likelihood of knowledge translation into policy and practice. The aim of this study was to conduct stakeholder analyses in the five countries participating in the Programme for Improving Mental health carE (PRIME); evaluate a template used for cross-country comparison of stakeholder analyses; and assess the utility of stakeholder analysis for future use in mental health policy and systems research in LMIC. Using an adapted stakeholder analysis instrument, PRIME country teams in Ethiopia, India, Nepal, South Africa and Uganda identified and characterised stakeholders in relation to the proposed action: scaling-up mental health services. Qualitative content analysis was conducted for stakeholder groups across countries, and a force field analysis was applied to the data. Stakeholder analysis of PRIME has identified policy makers (WHO, Ministries of Health, non-health sector Ministries and Parliament), donors (DFID UK, DFID country offices and other donor agencies), mental health specialists, the media (national and district) and universities as the most powerful, and most supportive actors for scaling up mental health care in the respective PRIME countries. Force field analysis provided a means of evaluating cross-country stakeholder power and positions, particularly for prioritising potential stakeholder engagement in the programme. Stakeholder analysis has been helpful as a research uptake management tool to identify targeted and acceptable strategies for stimulating the demand for research amongst knowledge users, including policymakers and practitioners. Implementing these strategies amongst stakeholders at a country level will hopefully reduce the knowledge gap between research and policy, and improve health system outcomes for the programme.

Health librarians should keep up-to-date in a dynamic environment and accept the importance of continuing personal development (CPD) and growth in their critical reflection and creative thinking skills. They also need to acknowledge the potential value of research activity and the challenges of ongoing improvement and development. Conference programmes may prove a useful source of stimulation, especially if supplemented by creativity techniques, action research and the ideal of 'finding flow'. The article analyses the themes and papers presented at the 10th International Conference on International Medical Librarianship (ICML) to identify opportunities for further research, literature reviews, assessment of practices and services, etc. Content analysis approach to conference papers and suggestions for further action including supplementing with techniques of creativity and group input. A fairly extensive list of further actions (although not intended to be exhaustive) is suggested for the sixteen conference themes. Although subjective, the list might help to stimulate growth in research on health librarianship and demonstrate how one source of stimulation--conference programmes (regularly presented to medical library communities)--can be used. Content analysis has proven a constructive means of generating research questions from a conference programme. Content analysis and other methods aimed at stimulating creative and progressive thinking, including brainstorming, force field analysis, De Bono's 6 hats, creative swiping and creative visualisation, may prove equally useful and require further investigation. To ensure an ongoing cycle, these can be linked to action research. © 2012 The authors. Health Information and Libraries Journal © 2012 Health Libraries Group.

Preliminary Thermal-Mechanical Sizing of Metallic TPS: Process Development and Sensitivity Studies

NASA Technical Reports Server (NTRS)

Poteet, Carl C.; Abu-Khajeel, Hasan; Hsu, Su-Yuen

2002-01-01

The purpose of this research was to perform sensitivity studies and develop a process to perform thermal and structural analysis and sizing of the latest Metallic Thermal Protection System (TPS) developed at NASA LaRC (Langley Research Center). Metallic TPS is a key technology for reducing the cost of reusable launch vehicles (RLV), offering the combination of increased durability and competitive weights when compared to other systems. Accurate sizing of metallic TPS requires combined thermal and structural analysis. Initial sensitivity studies were conducted using transient one-dimensional finite element thermal analysis to determine the influence of various TPS and analysis parameters on TPS weight. The thermal analysis model was then used in combination with static deflection and failure mode analysis of the sandwich panel outer surface of the TPS to obtain minimum weight TPS configurations at three vehicle stations on the windward centerline of a representative RLV. The coupled nature of the analysis requires an iterative analysis process, which will be described herein. Findings from the sensitivity analysis are reported, along with TPS designs at the three RLV vehicle stations considered.

Variables such as patient's anxiety, knowledge, number of medication changes, medication-induced side-effects and programme-derived benefits and conveniences have been reported or theorised to be important determinants of patient's attendance at worksite hypertension programmes. This study investigates whether these variables have predictive value in differentiating compliers from noncompliers attending a union-sponsored worksite hypertension programme for at least five years. Scores were created from a questionnaire distributed to 243 patients with a response rate of 98%. Compliance was defined as missing < or = 25% of scheduled clinic appointments. By discriminant statistical analysis scores for patient's anxiety, knowledge, number of medication changes, medication side-effects, perceived benefits and conveniences failed to show any predictive value for patient's compliance with appointment keeping.

Assessment of genetic diversity in a crop-breeding programme helps in the identification of diverse parental combinations to create segregating progenies with maximum genetic variability and facilitates introgression of desirable genes from diverse germplasm into the available genetic base. In the present study, 39 strains of vegetable amaranth (Amaranthus tricolor) were evaluated for eight morphological and seven quality traits for two test seasons to study the extent of genetic divergence among the strains. Multivariate analysis showed that the first four principal components contributed 67.55% of the variability. Cluster analysis grouped the strains into six clusters that displayed a wide range of diversity for most of the traits. Cluster analysis has proved to be an effective method in grouping strains that may facilitate effective management and utilisation in crop-breeding programmes. The diverse strains falling in different clusters were identified, which can be utilised in different hybridisation programmes to develop high-foliage-yielding varieties rich in nutritional components.

Modernised Portuguese schools - From IAQ and thermal comfort towards energy efficiency plans

NASA Astrophysics Data System (ADS)

Pereira, Luisa Maria Dias

A major rehabilitation and refurbishment programme of secondary school buildings has been carried out in the last few years in Portugal, led by the state-owned company Parque Escolar E.P.E. (PE), known as Secondary School Buildings Modernisation Programme. This programme took into consideration renewable energy systems, mostly solar panels for domestic hot water (DHW) production. Nevertheless, with the introduction of HVAC systems in buildings that were previously naturally ventilated, an increase on energy consumption has been verified. During the first occupancy phase of new and refurbished buildings, energy and indoor climate quality (ICQ) audits are important strategies to improve the buildings’ energy use. In new buildings, the most common errors are due to poor operation and management. Schools energy management programmes often result in a list of energy efficiency measures that do not necessarily reflect occupants’ conditions or satisfaction. They are more directed to management control and comparison with benchmarks of energy use/m2 or cost/student to assess energy efficiency. In all cases, monitoring and consumption patterns are mandatory. In this context, this thesis aims at developing energy efficiency plans (EEP) for modernised Portuguese school buildings. The framework of the thesis starts with the development of an international overview of the recent research and development in the field of energy consumption in schools [searching for statistical benchmarks that could contribute to an accurate school building indicator (SBI)]. Then, based on a database provided by Parque Escolar, an energy consumption assessment of Portuguese school buildings is presented, between the pre and post intervention phases. Drawing on this procedure, eight representative modernised secondary schools were selected, geographically and climatically distributed. After, an energy audit and indoor environment quality (IEQ) monitoring is performed in this schools selection. The continuous monitoring period varied between schools, from a minimum of 48h monitoring up to three weeks, during the mid-season [spring - autumn period (excluding summer vacation) in 2013]. Air exchange rates (AER), more specifically infiltration rates, are quantified aiming at determining the current airtightness condition of the refurbished schools. A subjective IEQ assessment is also performed, focusing on occupants’ feedback, providing insight on the potential linkages between energy use and occupants’ satisfaction and comfort. The thesis builds on the current EEP panorama and practice, which is based only on cost/energy control, extending it to address the equilibrium between IEQ evaluation and occupants’ perceived conditions/preferences. This approach is applied in two schools - selected based on the previous study on energy and IEQ conditions of the eight schools. The EEP methodology starts by deepening the knowledge of each school, mostly focusing on crossing the schools occupancy schedule with systems operation [(mainly those controlled by the building management system (BMS)]. An analysis on recently updated legislation is also performed (in particular fresh air flow rates requirements). It is shown that some potential energy savings can be achieved and that IEQ conditions can be improved at very low or even negligible costs. Other considerations, namely addressing the thermal energy production systems of the schools (e.g., boilers scheduling), the lighting systems (e.g., lighting circuits) and non-controlled plug loads, are also mentioned. Based upon all these findings, a handbook of good practice is drafted for secondary school buildings in Portugal. This EEP is accompanied by a list of Energy Efficiency Measures (EEM). It is proposed that this document is headed by a School - Energy Performance Certificate (S-EPC) based on the billed energy consumption. This document suggests the establishment of the figure of the Energy Manager.

Impact of participation in a theatre programme on quality of life among older adults with chronic conditions: a pilot study.

PubMed

Yuen, Hon Keung; Mueller, Kris; Mayor, Ellise; Azuero, Andres

2011-12-01

The purpose of this mixed methods study was to evaluate the effect of participation in the "Seasoned Arts At the Samford for You" (SAASY) programme, which included a 6-week acting class and four public performances, on the psychological well-being and health-related quality of life of older adults. Twelve older adults with chronic conditions from a low-income senior apartment and a senior living community participated in the programme. The acting class, led by two professional artists, met for a 2-hour class weekly for six weeks. Participants completed the General Well-being Schedule (GWBS) and the 36-Item Short-Form Health Survey (SF-36) both at the beginning of the programme and one month after the programme ended. In addition, participants were individually interviewed to explore the perceived impact of the theatre programme on their well-being. Participants reported a significantly higher score in the GWBS and on the physical but not on the mental component summary of the SF-36 at post-SAASY programme. Content analysis of the interview transcripts revealed that participants attained an improved sense of self-worth and self-advocacy and overcame self-imposed limitations. Results showed improvement in psychological well-being and health-related quality of life, most notably in the physical health component of SF-36 after participating in the programme. Practice implications for occupational therapists using drama as a creative leisure occupation to promote health among older adults with chronic conditions may involve analysis of participants' occupational profile, identification of deficit areas and adaptation of the acting programme content to meet specific needs and goals. The present study used a pretest and post test one group design that has numerous inherent limitations that affect the ability to make valid inferences from study findings. A more rigorous research design with a wait-listed control group and collection of outcome measures immediately after the acting class as well as at three months follow-up is essential in validating the present findings. Outcome measures used in future studies to evaluate the health benefits of a theatre programme should focus on ameliorating the effects of disease on disability (such as functional mobility, everyday cognitive function and activities of daily living) in addition to prevention.

2014-01-01

Background Acquired brain injury (ABI), often arising from stroke or trauma, is a common cause of long-term disability, physical inactivity and poor health outcomes globally. Individuals with ABI face many barriers to increasing physical activity, such as impaired mobility, access to services and knowledge regarding management of physical activity. Self-management programmes aim to build skills to enable an individual to manage their condition, including their physical activity levels, over a long period of time. Programme delivery modes can include traditional face-to-face methods, or remote delivery, such as via the Internet. However, it is unknown how effective these programmes are at specifically improving physical activity in community-dwelling adults with ABI, or how effective and acceptable remote delivery of self-management programmes is for this population. Methods/Design We will conduct a comprehensive search for articles indexed on MEDLINE, EMBASE, CINAHL, PsychINFO, AMED, Cochrane Central Register of Controlled Trials (CENTRAL), PEDro and Science Citation Index Expanded (SCI-EXPANDED) databases that assess the efficacy of a self-management intervention, which aims to enhance levels of physical activity in adults living in the community with ABI. Two independent reviewers will screen studies for eligibility, assess risk of bias, and extract relevant data. Where possible, a meta-analysis will be performed to calculate the overall effect size of self-management interventions on physical activity levels and on outcomes associated with physical activity. A comparison will also be made between face-to-face and remote delivery modes of self-management programmes, in order to examine efficacy and acceptability. A content analysis of self-management programmes will also be conducted to compare aspects of the intervention that are associated with more favourable outcomes. Discussion This systematic review aims to review the efficacy of self-management programmes aimed at increasing physical activity levels in adults living in the community with ABI, and the efficacy and acceptability of remote delivery of these programmes. If effective, remote delivery of self-management programmes may offer an alternative way to overcome barriers and empower individuals with ABI to increase their levels of physical activity, improving health and general wellbeing.

Progress towards reducing mortality and malnutrition among children < 5 years of age has been less than needed to achieve related Millennium Development Goals. Therefore, several international agencies joined to 'Reposition children's right to adequate nutrition in the Sahel', starting with an analysis of current activities related to infant and young child nutrition (IYCN). The objectives of the present paper are to compare relevant national policies, training materials, programmes, and monitoring and evaluation activities with internationally accepted IYCN recommendations. These findings are available to assist countries in identifying inconsistencies and filling gaps in current programming. Between August and November 2008, key informants responsible for conducting IYCN-related activities in Burkina Faso were interviewed, and 153 documents were examined on the following themes: optimal breastfeeding and complementary feeding practices, prevention of micronutrient deficiencies, screening and treatment of acute malnutrition, prevention of mother-to-child transmission of HIV, food security and hygienic practices. National policy documents addressed nearly all of the key IYCN topics, specifically or generally. Formative research has identified some local barriers and beliefs related to general breastfeeding and complementary feeding practices, and other formative research addressed about half of the IYCN topics included in this review. However, there was little evidence that this formative research was being utilized in developing training materials and designing programme interventions. Nevertheless, the training materials that were reviewed do provide specific guidance for nearly all of the key IYCN topics. Although many of the IYCN programmes are intended for national coverage, we could only confirm with available reports that programme coverage extended to certain regions. Some programme monitoring and evaluation were conducted, but few of these provided information on whether the specific IYCN programme components were implemented as designed. Most surveys that were identified reported on general nutrition status indicators, but did not provide the detail necessary for programme impact evaluations. The policy framework is well established for optimal IYCN practices, but greater resources and capacity building are needed to: (i) conduct necessary research and adapt training materials and programme protocols to local needs; (ii) improve, carry out, and document monitoring and evaluation that highlight effective and ineffective programme components; and (iii) apply these findings in developing, expanding, and improving effective programmes. © 2011 Blackwell Publishing Ltd.

This paper describes the steps used in developing and piloting a structured education programme - the Structured Education Reminiscence-based Programme for Staff (SERPS). The programme aimed to prepare nurses and care assistants to use reminiscence when caring for people with dementia living in long-term care. Reminiscence involves facilitating people to talk or think about their past. Structured education programmes are used widely as interventions in randomised controlled trials. However, the process of developing a structured education programme has received little attention relative to that given to evaluating the effectiveness of such programmes. This paper makes explicit the steps followed to develop the SERPS, thereby making a contribution to the methodology of designing and implementing effective structured education programmes. The approach to designing the SERPS was informed by the Van Meijel et al. (2004) model (Journal of Advanced Nursing 48, 84): (1) problem definition, (2) accumulation of building blocks for intervention design, (3) intervention design and (4) intervention validation. Grounded theory was used (1) to generate data to shape the 'building blocks' for the SERPS and (2) to explore residents, family and staff's experience of using/receiving reminiscence. Analysis of the pilot data indicated that the programme met its objective of preparing staff to use reminiscence with residents with dementia. Staff were positive both about the SERPS and the use of reminiscence with residents with dementia. This paper outlines a systematic approach to developing and validating a structured education programme. Participation in a structured education programme is more positive for staff if they are expected to actively implement what they have learnt. Ongoing support during the delivery of the programme is important for successful implementation. The incorporation of client and professional experience in the design phase is a key strength of this approach to programme design. © 2012 Blackwell Publishing Ltd.

Background Disease management programmes are increasingly used to improve the efficacy and effectiveness of chronic care delivery. But, disease management programme development and implementation is a complex undertaking that requires effective decision-making. Choices made in the earliest phases of programme development are crucial, as they ultimately impact costs, outcomes and sustainability. Methods To increase our understanding of the choices that primary healthcare practices face when implementing such programmes and to stimulate successful implementation and sustainability, we compared the early implementation of eight cardiovascular disease management programmes initiated and managed by healthcare practices in various regions of the Netherlands. Using a mixed-methods design, we identified differences in and challenges to programme implementation in terms of context, patient characteristics, disease management level, healthcare utilisation costs, development costs and health-related quality of life. Results Shifting to a multidisciplinary, patient-centred care pathway approach to disease management is demanding for organisations, professionals and patients, and is especially vulnerable when sustainable change is the goal. Funding is an important barrier to sustainable implementation of cardiovascular disease management programmes, although development costs of the individual programmes varied considerably in relation to the length of the development period. The large number of professionals involved in combination with duration of programme development was the largest cost drivers. While Information and Communication Technology systems to support the new care pathways did not directly contribute to higher costs, delays in implementation indirectly did. Conclusions Developing and implementing cardiovascular disease management programmes is time-consuming and challenging. Multidisciplinary, patient-centred care demands multifaceted changes in routine care. As care pathways become more complex, they also become more expensive. Better preparedness and training can prevent unnecessary delays during the implementation period and are crucial to reducing costs. PMID:24167456

Social acceptability and perceived impact of a community-led cash transfer programme in Zimbabwe

PubMed Central

2013-01-01

Background Cash transfer programmes are increasingly recognised as promising and scalable interventions that can promote the health and development of children. However, concerns have been raised about the potential for cash transfers to contribute to social division, jealousy and conflict at a community level. Against this background, and in our interest to promote community participation in cash transfer programmes, we examine local perceptions of a community-led cash transfer programme in Eastern Zimbabwe. Methods We collected and analysed data from 35 individual interviews and three focus group discussions, involving 24 key informants (community committee members and programme implementers), 24 cash transfer beneficiaries, of which four were youth, and 14 non-beneficiaries. Transcripts were subjected to thematic analysis and coding to generate concepts. Results Study participants described the programme as participatory, fair and transparent – reducing the likelihood of jealousy. The programme was perceived to have had a substantial impact on children’s health and education, primarily through aiding parents and guardians to better cater for their children’s needs. Moreover, participants alluded to the potential of the programme to facilitate more transformational change, for example by enabling families to invest money in assets and income generating activities and by promoting a community-wide sense of responsibility for the support of orphaned and vulnerable children. Conclusion Community participation, combined with the perceived impact of the cash transfer programme, led community members to speak enthusiastically about the programme. We conclude that community-led cash transfer programmes have the potential to open up for possibilities of participation and community agency that enable social acceptability and limit social divisiveness.

This paper outlines the conceptual background and findings from the pilot phase of TRAVELLERS--an early intervention programme designed to enhance protective factors for young people experiencing change, loss and transition events and early signs of emotional distress. The pilot study aimed to determine whether TRAVELLERS was a feasible, acceptable and promising intervention for young people within secondary schools in Aotearoa/New Zealand. The conceptual origins of the TRAVELLERS programme are described in terms of: adolescent mental health concerns; emerging mental health promotion theory and practice; and prevention and early intervention models. The key elements of the TRAVELLERS programme are described. The programme was piloted in two secondary schools, one rural and one urban with 34 participants (females n = 24, males n = 10). Evaluation methods included: review of programme materials; identification of potential selection tools appropriate to Year 9 students; analysis of selection questionnaire; and conduct of feedback from participants, facilitators and parents/caregivers. The TRAVELLERS programme provides a means of identifying and selecting young people who may benefit from participating in an early intervention programme. The programme has achieved a statistically significant reduction in participants' distress (p < 0.01). Young people were overwhelmingly enthusiastic about most aspects of TRAVELLERS. School personnel reported that TRAVELLERS was an appropriate and acceptable programme to the school. Targeted interventions provided within a supportive school environment can contribute to enhancing protective factors such as personal and interpersonal coping strategies, increased help-seeking behaviour, and young people feeling more positive about themselves and their lives. The pilot programme has been amended and prepared for a two year trial phase in 10 secondary schools during 2002-2003.

The techniques used for the analysis of thermally induced structural distortions of optical components such as scanning mirrors and telescope optics are outlined. Particular attention is given to the methodology used in the thermal and structural analysis of the GOES scan mirror, the optical analysis using Zernike coefficients, and the optical system performance evaluation. It is pointed out that the use of Zernike coefficients allows an accurate, effective, and simple linkage between thermal/mechanical effects and the optical design.

In 2014 the standardised incidence rate for breast cancer in Poland reached 51.6/100,000, while the mortality rate reached 14.8/100,000. The incidence rate for breast cancer in the EU was 106.6/100,000, the mortality rate - 22.4/100,000. In 2014 the incidence rate for cervical cancer in Poland was 8.8/100,000, the mortality rate - 4.5/100,000. The incidence rate in the EU was 11.3/100,000 and the mortality rate - 3.7/100,000. The aim of the paper was to establish the number of health policy programmes concerned with breast cancer and cervical cancer in women carried out in 2009-2014 by local government units, with specification of the type of programme, type of local government units that carried out the programmes and the costs of implementation of the programmes. The study was based on a desk research. The analysis covered data included in annual reports submitted by voivodes to Minister of Health, concerning health policy programmes implemented by local government units in 2009-2014. The greatest number of programmes concerned with prevention of breast cancer and cervical cancer were implemented in municipalities, followed by counties and finally - self-governed voivodeships. The number of programmes concerned with primary prevention was three times smaller (656) than the number of programmes concerned with secondary prevention (2,229). The greatest number of primary prevention programmes were implemented in Dolnośląskie, Wielkopolskie and Mazowieckie Voivodeships, and the greatest number of secondary prevention programmes - in Wielkopolskie, Mazowieckie and Zachodniopomorskie Voivodeships. It was found that the number of programmes implemented by particular local government units and the financial resources employed in the implementation of the programmes were different. It is probable that some of the initiatives of local government units related to secondary prevention coincide with the actions undertaken under the National Programme for Fighting Cancer. The entities that carry out breast cancer and cervical cancer prevention programmes need to coordinate their actions.

Work-related injuries and illness are prevalent and costly. Firefighting is especially hazardous and many firefighters sustain work-related injuries. Workplace health promotion programmes have shown positive return on investment (ROI). Little is known about how similar programmes would impact injury and cost among firefighters. To evaluate the impact of a workplace health promotion intervention on workers' compensation (WC) claims and medical costs among Oregon fire departments participating in the PHLAME (Promoting Healthy Lifestyles: Alternative Models' Effects) health promotion programme compared with Oregon fire departments not participating in PHLAME. Data from firefighters from four large urban fire departments in Oregon were evaluated using a retrospective quasi-experimental study design. Outcomes were (i) total annual firefighter WC claims, (ii) total annual incurred medical costs prior to and after implementation of the PHLAME firefighter worksite health promotion programme (iii) and an ROI analysis. Data were obtained from 1369 firefighters (mean age of 42 years, 91% white, 93% male). WC claims (P < 0.001) and medical costs (P < 0.01) were significantly lower among PHLAME fire departments compared with Oregon fire departments not participating in the programme. Fire departments participating in the PHLAME TEAM programme demonstrated a positive ROI of 4.61-1.00 (TEAM is used to indicate the 12-session peer-led health promotion programme). Fire department WC claims and medical costs were reduced after implementation of the PHLAME workplace health promotion programme. This is a low cost, team-based, peer-led, wellness programme that may provide a feasible, cost-effective means to reduce firefighter injury and illness rates.

Dementia training programmes for staff working in long-term care settings have been found to be effective in improving staff outcomes. This study investigated the impact of a dementia training programme for all Maltese nursing staff working in public nursing/residential homes on their knowledge, attitudes and confidence. Additionally, we identified the predictors of these domains before and after the programme. A 14-hour training programme focusing on dementia management, care and policy was developed for all nursing staff working in public nursing and residential homes in Malta. A pretest-posttest design was used to evaluate the participants' knowledge of dementia, attitudes and confidence in working with residents with dementia using validated tools. Demographic variables were measured and compared with each staff domain. The majority of nursing staff attended the training programme with 261 fully completed questionnaires being collected pre-training and 214 post-training. The programme significantly improved nursing staff knowledge, attitudes and confidence. Stepwise regression analysis of each staff domain showed that the strongest predictor in all models at pre-training was the intensity of previous training programmes. Furthermore, staff who attended previous training continued to improve in their attitudes and confidence following programme completion. The study continues to shed further evidence on the impact of dementia training programs on staff outcomes. It also indicated that the intensity of previous participation in dementia training programmes was related to the participants' knowledge, attitudes and confidence and that continual exposure to training had a cumulative effect.

The software package Transfer Analysis Code to Interface Thermal/Structural Problems (TRANCITS) was developed. The TRANCITS code is used to interface temperature data between thermal and structural analytical models. The use of this transfer module allows the heat transfer analyst to select the thermal mesh density and thermal analysis code best suited to solve the thermal problem and gives the same freedoms to the stress analyst, without the efficiency penalties associated with common meshes and the accuracy penalties associated with the manual transfer of thermal data.

Objectives The incidence and mortality of cervical cancer have halved since introduction of the Australian cervical screening programme in 1991, involving 2-yearly Pap smears from ages 18–69 years. In 2017, the programme changed to 5- yearly primary human papillomavirus (HPV) testing for women aged 25–74 years. This study investigated reasons for opposition to the renewed screening programme within the open-ended comments of an online petition, ‘Stop May 1st Changes to Pap Smears—Save Women’s Lives’, opposing the changes, which received over 70 000 signatures and almost 20 000 comments. Methods Content analysis of a random sample of 2000 comments, reflecting 10% of the 19 633 comments posted in February–March 2017. Results Nineteen codes were identified, reflecting four themes: (1) valuing women’s health and rights, (2) political statements, (3) concerns about healthcare funding cuts and (4) opposition to specific components of the new screening programme. The most prevalent codes were: placing value on women’s health (33%), concerns about increasing screening intervals (17%) and opposition to the changes related to personal experiences with cervical cancer or cervical abnormalities (15%). Concern about the key change in technology (HPV testing instead of Pap smears) was expressed in less than 3% of comments, and some opposition to the changes from health professionals was noted. Conclusions Screening changes within this selected group were perceived as threatening women’s health, as a political policy created by male decision-makers and as a cost-cutting exercise. Many commenters were concerned about increased screening intervals and later screening onset, but little opposition was expressed regarding the testing technology itself. This analysis may inform public education and communication strategies for future changes to cervical screening programmes internationally, to pre-emptively address specific concerns about the changes.

2015-06-01

Inverse thermal analysis of titanium gas-tungsten-arc welds using multiple constraint conditions is presented. This analysis employs a methodology that is in terms of numerical-analytical basis functions for inverse thermal analysis of steady-state energy deposition in plate structures. The results of this type of analysis provide parametric representations of weld temperature histories that can be adopted as input data to various types of computational procedures, such as those for prediction of solid-state phase transformations. In addition, these temperature histories can be used to construct parametric function representations for inverse thermal analysis of welds corresponding to other process parameters or welding processes whose process conditions are within similar regimes. The present study applies an inverse thermal analysis procedure that provides for the inclusion of constraint conditions associated with both solidification and phase transformation boundaries.

Brain-computer interfaces (BCIs) offer tremendous promise for improving the quality of life for disabled individuals. BCIs use spike sorting to identify the source of each neural firing. To date, spike sorting has been performed by either using off-chip analysis, which requires a wired connection penetrating the skull to a bulky external power/processing unit, or via custom application-specific integrated circuits that lack the programmability to perform different algorithms and upgrades. In this research, we propose and test the feasibility of performing on-chip, real-time spike sorting on a programmable smartdust, including feature extraction, classification, compression, and wireless transmission. A detailed power/performance tradeoff analysis using DVFS is presented. Our experimental results show that the execution time and power density meet the requirements to perform real-time spike sorting and wireless transmission on a single neural channel.

This study shows the use of SWOT to analyse students' perceptions of an environmental education joint master's programme in order to determine if it runs as originally planned. The open answers given by students highlight the inter-university nature of the master's, the technological innovation used as major points, and the weaknesses in the management coordination or the duplicate contents as minor points. The external analysis is closely linked with the students' future jobs, their labour opportunities available to them after graduation. The innovative treatment of the data is exportable to the evaluation of programmes of other degrees because it allows the description linked to its characteristics and its design through the students' point of view.

Research monitoring by US medical institutions to protect human subjects: compliance or quality improvement?

de Jong, Jean Philippe; van Zwieten, Myra C B; Willems, Dick L

2013-04-01

In recent years, to protect the rights and welfare of human subjects, institutions in the USA have begun to set up programmes to monitor ongoing medical research. These programmes provide routine, onsite oversight, and thus go beyond existing oversight such as investigating suspected misconduct or reviewing paperwork provided by investigators. However, because of a lack of guidelines and evidence, institutions have had little guidance in setting up their programmes. To help institutions make the right choices, we used interviews and document analysis to study how and why 11 US institutions have set up their monitoring programmes. Although these programmes varied considerably, we were able to distinguish two general types. 'Compliance' programmes on the one hand were part of the institutional review board office and set up to ensure compliance with regulations. Investigators' participation was mandatory. Monitors focused on documentation. Investigators could be disciplined, and could be obliged to take corrective actions. 'Quality-improvement' programmes on the other hand were part of a separate office. Investigators requested to be monitored. Monitors focused more on actual research conduct. Investigators and other parties received feedback on how to improve the research process. Although both types of programmes have their drawbacks and advantages, we argue that if institutions want to set up monitoring programmes, quality improvement is the better choice: it can help foster an atmosphere of trust between investigators and the institutional review board, and can help raise the standards for the protection of human subjects.

To determine the reach and adoption of a coach-led exercise training programme for lower limb injury prevention. Secondary analysis of data from a group-clustered randomised controlled trial. A periodised exercise training warm-up programme was delivered to players during training sessions over an 8-week preseason (weeks 1-8) and 18-week playing season. 1564 community Australian football players. Reach, measured weekly, was the number of players who attended training sessions. Adoption was the number of attending players who completed the programme in full, partially or not at all. Reasons for partial or non-participation were recorded. In week 1, 599 players entered the programme; 55% attended 1 training session and 45% attended > 1 session. By week 12, 1540 players were recruited but training attendance (reach) decreased to <50%. When players attended training, the majority adopted the full programme-ranging from 96% (week 1) to above 80% until week 20. The most common reasons for low adoption were players being injured, too sore, being late for training or choosing their own warm-up. The training programme's reach was highest preseason and halved at the playing season's end. However, when players attended training sessions, their adoption was high and remained close to 70% by season end. For sports injury prevention programmes to be fully effective across a season, attention also needs to be given to (1) encouraging players to attend formal training sessions and (2) considering the possibility of some form of programme delivery outside of formal training.

Background The Fatality Assessment and Control Evaluation (FACE) programme was established by the National Institute for Occupational Safety and Health to help prevent occupational traumatic fatalities by funding states to conduct targeted fatality investigations within cause-specific focus areas and associated prevention efforts. Purpose To investigate the impact of the state-based FACE programme on two previous focus areas. Methods A longitudinal time-series analysis spanning 22 years compared state fatality rates for occupational falls and electrocutions before and after FACE programme funding with states not receiving FACE programme funding. Lag periods were utilised to allow time for the programme to have an effect, and rates were adjusted for a variety of covariates. Separate analyses were conducted for each injury outcome. Results A reduction in fall fatality rates that was of borderline significance (1-year lag adjRR=0.92 (0.84 to 1.00)) and a non-significant reduction in electrocution fatality rates (3-year lag adjRR=0.92 (0.82 to 1.03)) were observed in states with FACE programme funding, Best-fit models presented two separate lag periods. Conclusions While it is challenging to quantitatively evaluate effectiveness of programmes such as FACE, the data suggest the FACE programme may be effective in preventing occupational injury deaths within its outcome focus areas throughout the state. It is important to look for ways to measure intermediate effects more precisely, as well as ways to maintain effects over time. PMID:22864251

To investigate the cost-effectiveness of a comprehensive programme for drug-resistant tuberculosis launched in four sites in China in 2011. In 2011-2012, we reviewed the records of 172 patients with drug-resistant tuberculosis who enrolled in the comprehensive programme and we collected relevant administrative data from hospitals and China's public health agency. For comparison, we examined a cohort of 81 patients who were treated for drug-resistant tuberculosis in 2006-2009. We performed a cost-effectiveness analysis, from a societal perspective, that included probabilistic uncertainty. We measured early treatment outcomes based on three-month culture results and modelled longer-term outcomes to facilitate estimation of the comprehensive programme's cost per disability-adjusted life-year (DALY) averted. The comprehensive programme cost 8837 United States dollars (US$) per patient treated. Low enrolment rates meant that some fixed costs were higher, per patient, than expected. Although the comprehensive programme appeared 30 times more costly than the previous one, it resulted in greater health benefits. The comprehensive programme, which cost US$ 639 (95% credible interval: 112 to 1322) per DALY averted, satisfied the World Health Organization's criterion for a very cost-effective intervention. The comprehensive programme, which included rapid screening, standardized care and financial protection, improved individual outcomes for MDR tuberculosis in a cost-effective manner. To support post-2015 global heath targets, the comprehensive programme should be expanded to non-residents and other areas of China.

Most policies addressing Aboriginal health in Australia promote initiatives that are based on empowerment principles. Articulated programme components are necessary to support personal and group empowerment and to assist individuals in gaining the sense of control and purposefulness needed to exert their political and personal power in the face of the severe stress and powerlessness faced by the Australian Aboriginal people. This paper aims to provide a detailed description of the mechanisms underpinning a 'bottom-up' empowerment initiative, the Family well-being empowerment and leadership programme (FWB), and to analyze how the programme supports empowerment. The five stages of FWB were described and the validity of this model was assessed through the combination of participatory observation, documentation analysis, literature review, semi-structured interviews and iterative feedback with different analytical perspectives. Our study results articulated four distinct programme components: the setting plus inter-relational, educational and experiential actions. FWB is an example of the promotion of both outcome and process pathways towards empowerment. Potential applications of the programme are discussed.

What was the programme theory of New Labour's Health System Reforms?

PubMed

Millar, Ross; Powell, Martin; Dixon, Anna

2012-01-01

To examine whether the Health System Reforms delivered the promise of being a coherent and mutually supporting reform programme; to identify the underlying programme theory of the reform programme; to reflect on whether lessons have been learned. Documentary analysis mapping the implicit and explicit programme theories about how the reforms intended to achieve its goals and outcomes. Semi-structured interviews with policy-makers to further understand the programme theory. The Health System Reforms assumed a 'one size fits all' approach to policy implementation with little recognition that some contexts can be more receptive than others. There was evidence of some policy evolution and rebalancing between the reform streams as policy-makers became aware of some perverse incentives and unforeseen consequences. Later elements aimed to restore balance to the system. The Health System Reforms do not appear to comprise a coherent and mutually supportive set of levers and incentives. They appear unbalanced with the centre of gravity favouring suppliers over commissioners. However, recent reform changes have sought to redress this imbalance to some extent, suggesting that lessons have been learned and policies have been adapted over time.

Remote sensing and implications for variable-rate application using agricultural aircraft

NASA Astrophysics Data System (ADS)

Thomson, Steven J.; Smith, Lowrey A.; Ray, Jeffrey D.; Zimba, Paul V.

2004-01-01

Aircraft routinely used for agricultural spray application are finding utility for remote sensing. Data obtained from remote sensing can be used for prescription application of pesticides, fertilizers, cotton growth regulators, and water (the latter with the assistance of hyperspectral indices and thermal imaging). Digital video was used to detect weeds in early cotton, and preliminary data were obtained to see if nitrogen status could be detected in early soybeans. Weeds were differentiable from early cotton at very low altitudes (65-m), with the aid of supervised classification algorithms in the ENVI image analysis software. The camera was flown at very low altitude for acceptable pixel resolution. Nitrogen status was not detectable by statistical analysis of digital numbers (DNs) obtained from images, but soybean cultivar differences were statistically discernable (F=26, p=0.01). Spectroradiometer data are being analyzed to identify narrow spectral bands that might aid in selecting camera filters for determination of plant nitrogen status. Multiple camera configurations are proposed to allow vegetative indices to be developed more readily. Both remotely sensed field images and ground data are to be used for decision-making in a proposed variable-rate application system for agricultural aircraft. For this system, prescriptions generated from digital imagery and data will be coupled with GPS-based swath guidance and programmable flow control.

Perioperative enhanced recovery programmes for gynaecological cancer patients.

Gynaecological malignancies contribute to 10 to 15% of cancers in women internationally. In recent years, a trend towards new perioperative care strategies has been documented as "Fast Track (FT) surgery", or "Enhanced Recovery Programmes" to replace some traditional approaches in surgical care. The FT multimodal programmes may enhance the postoperative recovery by means of reducing surgical stress. This systematic review aims to fully assess the beneficial and harmful effects of FT programmes in gynaecological cancer care. To evaluate the beneficial and harmful effects of FT programmes in gynaecological cancer care. We searched the following databases, The Cochrane Gynaecological Cancer Collaborative Review Group's Trial Register, the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 4, 2009, MEDLINE and EMBASE to November 2009. In addition, all reference lists of included trials were searched and experts in the gynaecological oncology community were contacted in an attempt to locate trials. All randomised controlled trials (RCTs) comparing any type of FT programmes for surgery in gynaecological cancer to conventional recovery strategies were included. Two review authors independently screened studies for inclusion. Since no RCTs were identified, data collection and analysis could not be performed. No studies were found that met the inclusion criteria. We currently have no evidence from high quality studies to support or refute the use of perioperative enhanced recovery programmes for gynaecological cancer patients. Further well-designed RCTs with standard FT programmes are needed.

Women's participation in rural credit programmes in Bangladesh and their demand for formal health care: is there a positive impact?

PubMed

Nanda, P

1999-08-01

Within the overall aim of poverty alleviation, development efforts have included credit and self-employment programmes. In Bangladesh, the major beneficiaries of such group-based credit programmes are rural women who use the loans to initiate small informal income-generating activities. This paper explores the benefits of women's participation in credit programmes on their own health seeking. Using data from a sample of 1798 households from rural Bangladesh, conducted in 1991-1992 through repeated random sampling of 87 districts covered by Grameen Bank, Bangladesh Rural Advancement Committee (BRAC) and Bangladesh Rural Development Board (BRDB), this paper addresses the question: does women's participation in credit programmes significantly affect their use of formal health care? A non-unitary household preference model is suggested to test the hypothesis that women's empowerment through participation in these programmes results in greater control of resources for their own demand for formal health care. The analysis controls for endogeneity due to self-selection and other unobserved village level factors through the use of a weighted two stage instrumental variable approach with village level fixed effects. The findings indicate a positive impact of women's participation in credit programmes on their demand for formal health care. The policy simulations on the results of this study highlight the importance of credit programmes as a health intervention in addition to being a mechanism for women's economic empowerment.

Development Of Metallic Thermal Protection System For The Expert Re-Entry Vehicle: Design Verification

NASA Astrophysics Data System (ADS)

Fatemi, Javad

2011-05-01

The thermal protection system of the EXPERT re-entry vehicle is subjected to accelerations, vibrations, acoustic and shock loads during launch and aero-heating loads and aerodynamic forces during re-entry. To fully understand the structural and thermomechanical performances of the TPS, heat transfer analysis, thermal stress analysis, and thermal buckling analysis must be performed. This requires complex three-dimensional thermal and structural models of the entire TPS including the insulation and sensors. Finite element (FE) methods are employed to assess the thermal and structural response of the TPS to the mechanical and aerothermal loads. The FE analyses results are used for the design verification and design improvement of the EXPERT thermal protection system.

Jackson, M. J.; Baker, J. R.; Townshend, J. R. G.; Gayler, J. E.; Hardy, J. R.

1983-01-01

The principal objectives of the UK SATMaP program are to determine thematic mapper (TM) performance with particular reference to spatial resolution properties and geometric characteristics of the data. So far, analysis is restricted to images from the U.S. and concentrates on spectra and radiometric properties. The results indicate that the data are inherently three dimensional compared with the two dimensional character of MSS data. Preliminary classification results indicate the importance of the near infrared band (TM 4), at least one middle infrared band (TM 5 or TM 6) and at least one of the visible bands (preferably either TM 3 or TM 1). The thermal infrared also appears to have discriminatory ability despite its coarser spatial resolution. For band 4 the forward and reverse scans show somewhat different spectral responses in one scene but this effect is absent in the other analyzed. From examination of the histograms it would appear that the full 8-bit quantization is not being effectively utilized for all the bands.

Biased Target Ion Beam Deposition and Nanoskiving for Fabricating NiTi Alloy Nanowires

NASA Astrophysics Data System (ADS)

Hou, Huilong; Horn, Mark W.; Hamilton, Reginald F.

2016-12-01

Nanoskiving is a novel nanofabrication technique to produce shape memory alloy nanowires. Our previous work was the first to successfully fabricate NiTi alloy nanowires using the top-down approach, which leverages thin film technology and ultramicrotomy for ultra-thin sectioning. For this work, we utilized biased target ion beam deposition technology to fabricate nanoscale (i.e., sub-micrometer) NiTi alloy thin films. In contrast to our previous work, rapid thermal annealing was employed for heat treatment, and the B2 austenite to R-phase martensitic transformation was confirmed using stress-temperature and diffraction measurements. The ultramicrotome was programmable and facilitated sectioning the films to produce nanowires with thickness-to-width ratios ranging from 4:1 to 16:1. Energy dispersive X-ray spectroscopy analysis confirmed the elemental Ni and Ti make-up of the wires. The findings exposed the nanowires exhibited a natural ribbon-like curvature, which depended on the thickness-to-width ratio. The results demonstrate nanoskiving is a potential nanofabrication technique for producing NiTi alloy nanowires that are continuous with an unprecedented length on the order of hundreds of micrometers.

Bluetongue virus (BTV) is an emerging transboundary disease in Europe, which can cause significant production losses among ruminants. The analysis presented here assessed the costs of BTV surveillance and vaccination programmes in Austria and Switzerland between 2007 and 2016. Costs were compared with respect to time, type of programme, geographical area and who was responsible for payment. The total costs of the BTV vaccination and surveillance programmes in Austria amounted to €23.6 million, whereas total costs in Switzerland were €18.3 million. Our analysis demonstrates that the costs differed between years and geographical areas, both within and between the two countries. Average surveillance costs per animal amounted to approximately €3.20 in Austria compared with €1.30 in Switzerland, whereas the average vaccination costs per animal were €6.20 in Austria and €7.40 in Switzerland. The comparability of the surveillance costs is somewhat limited, however, due to differences in each nation’s surveillance (and sampling) strategy. Given the importance of the export market for cattle production, investments in such programmes are more justified for Austria than for Switzerland. The aim of the retrospective assessment presented here is to assist veterinary authorities in planning and implementing cost-effective and efficient control strategies for emerging livestock diseases.

Research suggests that exercise training (ET) programmes may improve both physical and psychosocial functioning in implantable cardioverter defibrillator (ICD) recipients. Most of this research has been conducted by means of quantitative methods. However, knowledge of older ICD recipients' experiences of participating in such programmes is sparse. There is thus a need for more detailed qualitative data from the perspective of older patients. To describe older ICD recipients' experiences of participating in an ET programme. A qualitative design with semistructured interviews involving 12 older ICD recipients who had participated in a 3-month ET programme. Mini-disc recordings of the interviews were transcribed verbatim and analysed using content analysis. The analysis revealed two major themes: (1) 'increased confidence to engage in physical exertion'; and (2) 'increased satisfaction with life'. The first theme is illustrated by three subthemes: 'perceived support from physiotherapists', 'perceiving the heart rate monitor as a motivation to exercise', and 'perceiving peers as motivators for enjoyment and making the effort to exercise'. The second theme was illustrated by the following subthemes: 'perceived psychosocial benefits', 'perceived physical benefits', and 'exercise as a new health habit'. The findings indicate that exercising in a cardiac rehabilitation centre together with peers and supervised by skilled healthcare professionals may increase motivation to exert oneself, leading to emotional and physical benefits as well as a more social and active lifestyle for older ICD recipients.

An integrated thermal-structural finite element approach for efficient coupling of thermal and structural analysis is presented. New thermal finite elements which yield exact nodal and element temperatures for one dimensional linear steady state heat transfer problems are developed. A nodeless variable formulation is used to establish improved thermal finite elements for one dimensional nonlinear transient and two dimensional linear transient heat transfer problems. The thermal finite elements provide detailed temperature distributions without using additional element nodes and permit a common discretization with lower order congruent structural finite elements. The accuracy of the integrated approach is evaluated by comparisons with analytical solutions and conventional finite element thermal structural analyses for a number of academic and more realistic problems. Results indicate that the approach provides a significant improvement in the accuracy and efficiency of thermal stress analysis for structures with complex temperature distributions.

A wireless microvalve system was fabricated based on induction heating for flow control in microfluidics by sequential valve opening. In this approach, we used paraffin wax as a flow plug, which can be changed from solid to liquid with adjacent heating elements operated by induction heating. Programmable opening of valves was devised by using different thermal responses of metal discs to a magnetic field. Copper and nickel discs with a diameter of 2.5 mm and various thicknesses (50, 100 and 200 µm) were prepared as heating elements by a laser cutting method, and they were integrated in the microfluidic channel as part of the microvalve. A calorimetric test was used to measure the thermal properties of the discs in terms of kinds of metal and disc thickness. Sequential openings of the microvalves were performed using the difference in the thermal response of 100 µm thick copper disc and 50 µm thick nickel disc for short-interval openings and 200 µm thick copper disc and 100-µm-thick nickel disc for long-interval openings. The thermal effect on fluid samples as a result of induction heating of the discs was studied by investigating lysozyme denaturation. More heat was generated in heating elements made of copper than in those made of nickel, implying differences in the thermal response of heating elements made of copper and nickel. Also, the thickness of the heating elements affected the thermal response in the elements. Valve openings for short intervals of 1-5 s and long intervals of 15-23 s were achieved by using two sets of heating elements. There was no significant change in lysozyme activity by increasing the temperature of the heating discs. This study demonstrates that a wireless sequentially actuated microvalve system can provide programmed valve opening, portability, ease of fabrication and operation, disposability, and low cost.

Development of Advanced Multizone Facilities for Microgravity Processing

NASA has been interested in experimental ground based study to investigate the fundamental processes involved in phase transformation processes during growth of metallic, nonmetallic and electronic materials. Solidification, vapor growth and solution growth techniques of growing crystals are of special interest because of the inherent importance of convection in the nutrient solution. Convection enhances the mass transport through the nutrient and results in faster growth rates. Availability of low gravity environment of space has provided scientists a new variable to control the extent of convection and thus isolate the diffusive phenomena for their better understanding. The thermal gradient at the liquid-solid interface is determined by the alloy characteristics, the hot zone temperature, cold zone temperature and the width of the insulating zone. The thermal profiles get established by the existing material and geometrical constraints of the experimental set up. The major effort under this research was devoted to designing a programmable furnace which can be used to obtain thermal profiles along the length of the sample as per the demands of the scientists. The furnace did not have active cooling of the zones. Only active heating and passive cooling were utilized.

Metal bioaccumulation and induction of biomarkers such as lipid peroxidation (LPO), superoxide dismutase (SOD), catalase (CAT), glutathione S transferase (GST), reduced glutathione (GSH) and DNA damage are potential indicators of stress in Channa punctatus exposed to effluents. In canal water, receiving thermal power plant discharges, Fe and Ni concentrations exceeded the recommended guidelines set by the United Nations Environment Programme Global Environment Monitoring System (UNEPGEMS). Fe was highly bioavailable and accumulated in all organs (liver, kidney, muscle and integument). The highest metal pollution index (MPI) value of 41.2 was observed in kidney and the lowest 13.5 in muscle tissue. LPO, SOD, CAT and GST levels were significantly higher in liver and kidney, whereas GSH levels declined significantly compared to fish from the reference site. Concomitant damage to DNA was observed with significantly higher mean tail length in the exposed fish gill cells (26.5µm) and in liver (20.8µm) compared to reference fish. Therefore, it can be concluded that the thermal power plant effluent had the potential to cause oxidative stress and DNA damage in C. punctatus. Copyright © 2016 Elsevier Inc. All rights reserved.

The law of statistical physics dictates that generic closed quantum many-body systems initialized in nonequilibrium will thermalize under their own dynamics. However, the emergence of many-body localization (MBL) owing to the interplay between interaction and disorder, which is in stark contrast to Anderson localization, which only addresses noninteracting particles in the presence of disorder, greatly challenges this concept, because it prevents the systems from evolving to the ergodic thermalized state. One critical evidence of MBL is the long-time logarithmic growth of entanglement entropy, and a direct observation of it is still elusive due to the experimental challenges in multiqubit single-shot measurement and quantum state tomography. Here we present an experiment fully emulating the MBL dynamics with a 10-qubit superconducting quantum processor, which represents a spin-1 /2 X Y model featuring programmable disorder and long-range spin-spin interactions. We provide essential signatures of MBL, such as the imbalance due to the initial nonequilibrium, the violation of eigenstate thermalization hypothesis, and, more importantly, the direct evidence of the long-time logarithmic growth of entanglement entropy. Our results lay solid foundations for precisely simulating the intriguing physics of quantum many-body systems on the platform of large-scale multiqubit superconducting quantum processors.

The authors investigated the in-situ processing temperatures and effects of various formulation additives on the formation of ultraviolet (UV) excitable chromophores, in the thermal lamination and curing of ethylene-vinyl acetate (EVA) encapsulants. A programmable, microprocessor-controlled, double-bag vacuum laminator was used to study two commercial as formulated EVA films, A9918P and 15295P, and solution-cast films of Elvaxrm (EVX) impregnated with various curing agents and antioxidants. The results show that the actual measured temperatures of EVA lagged significantly behind the programmed profiles for the heating elements and were affected by the total thermal mass loaded inside the laminator chamber. The antioxidant Naugardmore » P{trademark}, used in the two commercial EVA formulations, greatly enhances the formation of UV-excitable, short chromophores upon curing, whereas other tested antioxidants show little effect.

Mandanici, Emanuele; Conte, Paolo

2016-10-01

The ChoT project aims at analysing the potential of aerial thermal imagery to produce large scale datasets for energetic efficiency analyses and policies in urban environments. It is funded by the Italian Ministry of Education, University and Research (MIUR) in the framework of the SIR 2014 (Scientific Independence of young Researchers) programme. The city of Bologna (Italy) was chosen as the case study. The acquisition of thermal infrared images at different times by multiple aerial flights is one of the main tasks of the project. The present paper provides an overview of the ChoT project, but it delves into some specific aspects of the data processing chain: the computing of the radiometric quantities of the atmosphere, the estimation of surface emissivity (through an object-oriented classification applied on a very high resolution multispectral image, to distinguish among the major roofing materials) and sky-view factor (by means of a digital surface model). To collect ground truth data, the surface temperature of roofs and road pavings was measured at several locations at the same time as the aircraft acquired the thermal images. Furthermore, the emissivity of some roofing materials was estimated by means of a thermal camera and a contact probe. All the surveys were georeferenced by GPS. The results of the first surveying campaign demonstrate the high sensitivity of the model to the variability of the surface emissivity and the atmospheric parameters.

Hydrodynamic and thermal modeling of two-dimensional microdroplet arrays for digitized heat transfer

NASA Astrophysics Data System (ADS)

Baird, Eric S.

This document describes hydrodynamic and thermal modeling of two-dimensional microdroplet arrays for use in digitized heat transfer (DHT), a novel active thermal management technique for high power density electronics and integrated microsystems. In DHT, thermal energy is transported by a discrete array of electrostatically activated microdroplets of liquid metals, alloys or aqueous solutions with the potential of supporting significantly higher heat transfer rates than classical air-cooled heat sinks. Actuation methods for dispensing and transporting individual fluid slugs with a high degree of precision and programmability are described, with simple approximate formulae for net forces for steady state and transient velocities in terms of known parameters. A modified cavity flow solver is developed to provide details on the internal flow properties of a translating microdroplet and used to detail the effects of droplet curvature, internal mixing, Peclet number and other parameters on the heat transfer capabilities of a discretized liquid flow. The concept of Nusselt number is generalized to an individual fluid slug and shown to oscillate with a period equal to the droplet's mixing rate. In whole, DHT is demonstrated to be a viable new alternative for achieving the most important objectives of electronic cooling (i.e., minimization of the maximum substrate temperature, reduction of the substrate temperature gradient and removal of substrate hot spots) and a sound fundamental description of the method's electro-, hydro- and thermodynamics is provided.

The antiretroviral adherence club intervention was rolled out in primary health care facilities in the Western Cape province of South Africa to relieve clinic congestion, and improve retention in care, and treatment adherence in the face of growing patient loads. We adopted the realist evaluation approach to evaluate what aspects of antiretroviral club intervention works, for what sections of the patient population, and under which community and health systems contexts, to inform guidelines for scaling up of the intervention. In this article, we report on a step towards the development of a programme theory-the assumptions of programme designers and health service managers with regard to how and why the adherence club intervention is expected to achieve its goals and perceptions on how it has done so (or not). We adopted an exploratory qualitative research design. We conducted a document review of 12 documents on the design and implementation of the adherence club intervention, and key informant interviews with 12 purposively selected programme designers and managers. Thematic content analysis was used to identify themes attributed to the programme actors, context, mechanisms, and outcomes. Using the context-mechanism-outcome configurational tool, we provided an explanatory focus of how the adherence club intervention is roll-out and works guided by the realist perspective. We classified the assumptions of the adherence club designers and managers into the rollout, implementation, and utilisation of the adherence club programme, constructed around the providers, management/operational staff, and patients, respectively. Two rival theories were identified at the patient-perspective level. We used these perspectives to develop an initial programme theory of the adherence club intervention, which will be tested in a later phase. The perspectives of the programme designers and managers provided an important step towards developing an initial programme theory, which will guide our realist evaluation of the adherence club programme in South Africa.

Family members lack the ability to care for suicidal relatives. Nurses have a responsibility to improve family members' ability to care for their suicidal relatives. The aims of this study were to design a suicide education programme for nurses to educate family caregivers and to evaluate the longitudinal (12 months after the educational programme) effects of a suicide care education programme on the ability of families to care for suicidal relatives. A randomised controlled trial was conducted. The study population (n=61) was composed of the family caregivers of suicidal individuals. Several caregivers (n=26) were randomly allocated to an experimental group who attended a two-hour suicide care education programme, and the other caregivers (n=35) represented a control group who did not attend the education programme. All of the participants were given a questionnaire at baseline, 3 months, and 12 months during the period from 2009 to 2011. The results of the longitudinal effects of the suicide care education programme demonstrated that there were statistically significant differences after the educational programme as compared to before the programme with regard to "seeking assistance from resources" and the ability to care for those who were once suicidal. The longitudinal results of both groups showed that there was a significant difference in terms of "caring ability" at 12 months. The results of a multiple linear regression analysis indicated that evaluations performed at the three-month time point were able to effectively predict success in "seeking assistance from resources", "caring ability"; caring ability was also significantly improved among those who engaged in the educational programme at the 12-month time point. The suicide care education programme had long-term effects for family caregivers caring for their suicidal relatives. Nurses could employ this suicide care education programme to improve the ability of family caregivers to care for their suicidal relatives. Crown Copyright © 2012. Published by Elsevier Ltd.

SUMMARY The Universal Newborn Hearing Screening (UNHS) programme aims at achieving early detection of hearing impairment. Subsequent diagnosis and intervention should follow promptly. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for early Identification, Intervention and Care of Hearing Impaired Children", the limitations and strengths of current UNHS programs in Italy have been analysed by a group of professionals working in tertiary centres involved in regional UNHS programmes, using SWOT analysis and a subsequent TOWS matrix. Coverage and lost-to-follow up rates are issues related to UNHS programmes. Recommendations to improve the effectiveness of the UNHS programme have been identified. The need for homogeneous policies, high-quality information and dissemination of knowledge for operators and families of hearing-impaired children emerged from the discussion. PMID:27054385

Mozambique launched its revitalized community health programme in 2010 in response to inequitable coverage and quality of health services. The programme is focused on health promotion and disease prevention, with 20 % of community health workers' (known in Mozambique as Agentes Polivalentes Elementares (APEs)) time spent on curative services and 80 % on activities promoting health and preventing illness. We set out to conduct a health system and equity analysis, exploring experiences and expectations of APEs, community members and healthcare workers supervising APEs. This exploratory qualitative study captured the perspectives of a range of participants including women caring for children under 5 years (service clients), community leaders, service providers (APEs) and their supervisors. Participants in the Moamba and Manhiça districts, located in Maputo Province (Mozambique), were selected purposively. In total, 29 in-depth interviews and 9 focus group discussions were conducted in the local language and/or Portuguese. A framework approach was used for analysis, assisted by NVivo10 software. Our analysis revealed that health equity is viewed as linked to the quality and coverage of the APE programme. Demand and supply factors interplay to shape health equity. The availability of responsive and appropriate services led to tensions between community expectations for curative services (and APEs' willingness to perform them) and official policy focusing APE efforts mainly on preventive services and health promotion. The demand for more curative services by community members is a result of having limited access to healthcare services other than those offered by APEs. This study highlights the need to pay attention to the determinants of demand and supply of community interventions in health, to understand the opportunities and challenges of the difficult interface role played by APEs and to create communication among stakeholders in order to build a stronger, more effective and equitable community programme.

Benefit-Cost Analysis of Foot and Mouth Disease Control in Large Ruminants in Cambodia.

Foot and mouth disease (FMD) is endemic in Cambodia and throughout the Greater Mekong Subregion and causes significant losses to rural smallholders owning the majority of the national large ruminant population. However, due to underreporting, paucity of knowledge of FMD impacts, limited veterinary capacity and deficits of data available for analysis, the quantifiable benefits of a national FMD control programme are unknown. To address this deficit, existing literature and research data from the 'Best practice health and husbandry of cattle, Cambodia' project conducted between 2007 and 2012, were used to develop a three-phase analysis framework to: assess the impacts of the recent widespread FMD epizootic in Cambodia in 2010, conduct a value chain analysis of the large ruminant market and estimate the costs and benefits for a national large ruminant biannual FMD vaccination programme. A trader survey conducted in 2010-2011 provided cattle and buffalo value chain information and was matched to village herd structure data to calculate a total large ruminant farm-gate value of USD 1.271 billion in 2010. Monte Carlo simulation modelling that implemented a 5-year biannual vaccination programme at a cost of USD 6.3 an animal per year identified a benefit-cost ratio of 1.40 (95% CI 0.96-2.20) when accounting for recent prices of cattle and buffalo in Cambodia and based on an expected annual incidence of 0.2 (assuming one major epizootic in the 5-year vaccination programme). Given that the majority of the large ruminants are owned by rural smallholders, and mostly the poor are involved in agricultural employment, the successful implementation of an FMD control programme in Cambodia would be expected to avoid estimated losses of USD 135 million; equivalent to 10.6% of the 2010 farm-gate value and contributing to important reductions in rural poverty and food insecurity. © 2014 Blackwell Verlag GmbH.

In light of the decline in donor HIV funding, HIV programmes increasingly need to assess their available and potential resources and maximize their utilization. This article presents lessons learned related to how countries have addressed the sustainability of HIV programmes in a stakeholder-driven sustainability analysis. During HIV/AIDS Programme Sustainability Analysis Tool (HAPSAT) applications in six countries (Benin, Guyana, Kenya, Lesotho, Sierra Leone and South Sudan), stakeholders identified key sustainability challenges for their HIV responses. Possible policy approaches were prepared, and those related to prioritization and resource mobilization are analysed in this article. The need to prioritize evidence-based interventions and apply efficiency measures is being accepted by countries. Five of the six countries in this study requested that the HAPSAT team prepare 'prioritization' strategies. Countries recognize the need to prepare for an alternative to 'universal access by 2015', acknowledging that their capacity might be insufficient to reach such high-coverage levels by then. There is further acceptance of the importance of reaching the most-at-risk, marginalized populations, as seen, for example, in South Sudan and Sierra Leone. However, the pace at which resources are shifting towards these populations is slow. Finally, only two of the six countries, Kenya and Benin, chose to examine options for generating additional financial resources beyond donor funding. In Kenya, three non-donor sources were recommended, yet even if all were to be implemented, it would cover only 25% of the funding needed. Countries are increasingly willing to address the challenges of HIV programme sustainability, yet in different ways and with varying urgency. To secure achievements made to date and maximize future impact, countries would benefit from strengthening their strategic plans, operational plans and funding proposals with concrete timelines and responsibilities for addressing sustainability issues.

Strokes are often preceded by a transient ischaemic attack (TIA) or 'minor' stroke. The immediate period after a TIA/minor stroke is a crucial time to initiate secondary prevention. However, the optimal approach to prevention, including non-pharmacological measures, after TIA is not clear. To systematically review evidence about the effectiveness of delivering secondary prevention, with lifestyle interventions, in comprehensive rehabilitation programmes, initiated within 90 days of a TIA/minor stroke. Also, to categorise the specific behaviour change techniques used. The review identified randomised controlled trials by searching the Cochrane Library, Ovid MEDLINE, Ovid EMBASE, Web of Science, EBSCO CINAHL and Ovid PsycINFO. Two review authors independently screened titles and abstracts for eligibility (programmes initiated within 90 days of event; outcomes reported for TIA/minor stroke) and extracted relevant data from appraised studies; a meta-analysis was used to synthesise the results. A total of 31 potentially eligible papers were identified and four studies, comprising 774 patients post-TIA or minor stroke, met the inclusion criteria; two had poor methodological quality. Individual studies reported increased aerobic capacity but meta-analysis found no significant change in resting and peak systolic blood pressure, resting heart rate, aerobic capacity, falls, or mortality. The main behaviour change techniques were goal setting and instructions about how to perform given behaviours. There is limited evidence of the effectiveness of early post-TIA rehabilitation programmes with preventive lifestyle interventions. Further robust randomised controlled trials of comprehensive rehabilitation programmes that promote secondary prevention and lifestyle modification immediately after a TIA are needed. © British Journal of General Practice 2017.

Research suggests that guided self-determination programmes can support self-management of diabetes by empowering self-determined goal setting and competence building. As most research in this area has focused on people with type 1 diabetes, knowledge is lacking on how adults with type 2 diabetes mellitus experience participation in such programmes. This study reports the modelling phase of a complex intervention design that explored the experiences of adults with type 2 diabetes who participated in a nurse-led guided self-determination programme in general practice and examines how the programme affected patients' motivation to self-manage diabetes. The qualitative design with semistructured interviews included 9 adults with type 2 diabetes who participated in the programme. Qualitative content analysis was used to analyse the data. The findings indicate that the participants experienced new life possibilities after participating in the programme, which seemed to have a positive influence on their motivation for self-management. Through reflections about how to live with diabetes, the participants reinterpreted their life with diabetes by gradually developing a closer relationship with the disease, moving towards acceptance. The fact that dialogue with the nurses was seen to be on an equal footing helped support the participants to become more self-determined.
