    Engineering trade-off studies of life support system architecture and technology options were conducted for potential lunar surface mission scenarios within NASA's Constellation Program. The scenarios investigated are based largely on results of the NASA Lunar Architecture Team (LAT) Phase II study. In particular, the possibility of Hosted Sortie missions, the high cost of power during eclipse periods, and the potential to reduce life support consumables through scavenging, in-situ resources, and alternative EVA technologies were all examined. These trade studies were performed within the Systems Integration, Modeling and Analysis (SIMA) element of NASA's Exploration Life Support (ELS) technology development project. The tools and methodology used in the study are described briefly, followed by a discussion of mission scenarios, life support technology options and results presented in terms of equivalent system mass for various regenerative life support technologies and architectures. Three classes of repeated or extended lunar surface missions were investigated in this study along with several life support resource scenarios for each mission class. Individual mission durations of 14 days, 90 days and 180 days were considered with 10 missions assumed for each at a rate of 2 missions per year. The 14-day missions represent a class of Hosted Sortie missions where a pre-deployed and potentially mobile habitat provides life support for multiple crews at one or more locations. The 90-day and 180-day missions represent lunar outpost expeditions with a larger fixed habitat. The 180-day missions assume continuous human presence and must provide life support through eclipse periods of up to 122 hours while the 90-day missions are planned for best-case periods of nearly continuous sunlight. This paper investigates system optimization within the assumptions of each scenario and addresses how the scenario selected drives the life support system to different designs

    Full Text Available Support from top management and others is agreed to be an important factor in information systems success and failure, but little is written about how it has its effect and how it might be managed to a project's advantage. A recently developed conceptual framework is described. It covers the nature and forms of support, the way support affects project outcomes, the bases on which support is provided, and the strategies by which support may be managed. The framework is used to analyse a case study in several stages. At the end of the analysis of each stage, the framework's utility is assessed in terms of its explanatory value and the practical advice it suggests. Areas for further research are identified.

    Tin oxide was supported on aluminium oxide, titanium oxide, magnesium oxide and silicon oxide, and the resulting interactions between the components in the prepared samples and after reduction were characterized by Moessbauer spectroscopy. It was observed that in the oxide state, tin is present as SnO{sub 2} on alumina, magnesia and silica, but on titania tin occupies Ti sites in the structure. After hydrogen treatment at high temperatures, tin is reduced from Sn(4) to Sn(2) on alumina and titania; it is reduced from Sn(4) to Sn(0) on silica, and is practically not reduced on magnesia. These results reveal the degree of interaction between tin and the different supports studied.

  7. Assured Mission Support Space Architecture (AMSSA) study

    1993-01-01

    The assured mission support space architecture (AMSSA) study was conducted with the overall goal of developing a long-term requirements-driven integrated space architecture to provide responsive and sustained space support to the combatant commands. Although derivation of an architecture was the focus of the study, there are three significant products from the effort. The first is a philosophy that defines the necessary attributes for the development and operation of space systems to ensure an integrated, interoperable architecture that, by design, provides a high degree of combat utility. The second is the architecture itself; based on an interoperable system-of-systems strategy, it reflects a long-range goal for space that will evolve as user requirements adapt to a changing world environment. The third product is the framework of a process that, when fully developed, will provide essential information to key decision makers for space systems acquisition in order to achieve the AMSSA goal. It is a categorical imperative that military space planners develop space systems that will act as true force multipliers. AMSSA provides the philosophy, process, and architecture that, when integrated with the DOD requirements and acquisition procedures, can yield an assured mission support capability from space to the combatant commanders. An important feature of the AMSSA initiative is the participation by every organization that has a role or interest in space systems development and operation. With continued community involvement, the concept of the AMSSA will become a reality. In summary, AMSSA offers a better way to think about space (philosophy) that can lead to the effective utilization of limited resources (process) with an infrastructure designed to meet the future space needs (architecture) of our combat forces.

    2002-01-01

    The paper presents a study where upgrading of an existing wastewater treatment plant was supported by simulation. The aim of the work was to decide between two technologies to improve nitrogen removal: a conventional activated sludge process (ASP) and a moving bed biofilm reactor (MBBR). To perform simulations, the mathematical models of both processes were designed. The models were calibrated based on data from ASP and MBBR pilot plants operating in parallel on the existing plant. Only two kinetic parameters needed to be adjusted to represent the real plant behaviour. Steady-state analyses have shown a similar efficiency of both processes in relation to carbon removal, but improved performance of MBBR in relation to nitrogen removal. Better performance of MBBR can be expected especially at low temperatures. Simulations have not confirmed the expected less volume required for the MBBR process. Finally, the MBBR was chosen for plant upgrading. The developed process model will be further used to evaluate the final plant configuration and to optimise the plant operating parameters.

    A new concept in magnetic levitation and control is introduced for levitation above a plane. A set of five vertical solenoid magnets mounted flush below the plane supports and controls the model in five degrees of freedom. The compact system of levitation coils is contained in a space 2.4 m (96 in) diameter by 1 m (40 in) deep with the top of the levitation system 0.9 m (36 in) below the center line of the suspended model. The levitated model has a permanent magnet core held in position by the five parallel superconductive solenoids symmetrically located in a circle. The control and positioning system continuously corrects for model position in five dimensions using computer current pulses superimposed on the levitation coil base currents. The conceptual designs include: superconductive and Nd-Fe-B permanent magnet model cores and levitation solenoids of either superconductive, cryoresistive, or room temperature windings.

    Othman, Noraini; Nasurdin, Aizzat Mohd

    2013-11-01

    This study addressed the question of whether social support (supervisor support and co-worker support) could contribute to the variance in work engagement. Nurses, as customer-contact employees, play an important role in representing the organization's competence. Their attitudes and behaviour toward patients has a significant influence on patients' satisfaction and perception of quality of service. The sample comprised 402 staff nurses working in three general hospitals in Peninsular Malaysia. Variables included demographic information, Utrecht Work Engagement Scale and Social Support Scale. Data analysis included descriptive statistics, correlations and regression analysis. Findings indicated that supervisor support was positively related to work engagement. Co-worker support was found to have no effect on work engagement. Supervisory support is an important predictor of work engagement for nurses. Nursing management should provide more training to nurse supervisors and develop nurse mentoring programmes to encourage more support to nurses. © 2012 John Wiley & Sons Ltd.

    Climate change is one of the major challenges facing us on the Earth planet in the 21st century. Scientists build many models to simulate the past and predict the climate change for the next decades or century. Most of the models are at a low resolution with some targeting high resolution in linkage to practical climate change preparedness. To calibrate and validate the models, millions of model runs are needed to find the best simulation and configuration. This paper introduces the NASA effort on Climate@Home project to build a supercomputer based-on advanced computing technologies, such as cloud computing, grid computing, and others. Climate@Home computing infrastructure includes several aspects: 1) a cloud computing platform is utilized to manage the potential spike access to the centralized components, such as grid computing server for dispatching and collecting models runs results; 2) a grid computing engine is developed based on MapReduce to dispatch models, model configuration, and collect simulation results and contributing statistics; 3) a portal serves as the entry point for the project to provide the management, sharing, and data exploration for end users; 4) scientists can access customized tools to configure model runs and visualize model results; 5) the public can access twitter and facebook to get the latest about the project. This paper will introduce the latest progress of the project and demonstrate the operational system during the AGU fall meeting. It will also discuss how this technology can become a trailblazer for other climate studies and relevant sciences. It will share how the challenges in computation and software integration were solved.

  17. Integrated logistic support studies using behavioral Monte Carlo simulation, supported by Generalized Stochastic Petri Nets

    2000-07-01

    Studying large and complex industrial sites, requires more and more accuracy in modeling. In particular, when considering Spares, Maintenance and Repair / Replacement processes, determining optimal Integrated Logistic Support policies requires a high level modeling formalism, in order to make the model as close as possible to the real considered processes. Generally, numerical methods are used to process this kind of study. In this paper, we propose an alternate way to process optimal Integrated Logistic Support policy determination when dealing with large, complex and distributed multi-policies industrial sites. This method is based on the use of behavioral Monte Carlo simulation, supported by Generalized Stochastic Petri Nets. (author)

    Agriesti-Johnson, C; Dwyer, K; Steinbaugh, M

    1988-01-01

    The purpose of this study was to determine the degree of intercorrelation among dietitian, physician, and team nutrition support functions. Eight hundred and eighty dietitians and physicians were asked to respond to a questionnaire describing nutrition support functions as reported in the literature and validated by a panel of nutrition support physicians and dietitians. Two hundred and fifty-four completed questionnaires were included in the study, 84 from physicians and 170 from dietitians. Intercorrelations among function statements were subjected to factor analysis. The magnitude and consistency of factor loadings suggest that nutrition support is not perceived as independent components, but as a comprehensive pattern or structure. However, there was one important difference in perception. The sample tended to have an "enteral" orientation to the dietitian role and a "parenteral" orientation to the physician and team roles. The data support the contention that all members of nutrition support teams need a common core of knowledge and a set of highly developed process skills which can best be attained through an integrated, rather than segmented, approach to team training.

    For many years, studies about the cochlea have been mainly focused on sensory cells, i.e. the inner hair cell (IHC) and outer hair cell (OHC), and the neuron system. Supporting cells, such as Hensen's cells and Deiters' cells are less studied. Their physiological functions and other characteris-tics are not well documented. Nowadays, supporting cells are a new world attracting to scientists" inter-ests. The scope of this review is to detail the biological properties of the supporting cells, mainly Hensen's cells and Deiters' cells in the cochlea. Studies on this subject will be helpful in understanding physiology of the cochlea, and hopefully provide new approaches in treating diseases of inner ear.

    The aim of this work is to study the influence of the addition of different oxides to an alumina support, on surface acidity and platinum reducibility in platinum-based catalysts, as well as their effect on the activity and selectivity in CO preferential oxidation, in presence of hydrogen. A correlation between surface acidity and acid strength of surface sites and metal reducibility was obtained, being Pt-support interaction a function of the acid sites concentration under a particular temperature range. In platinum supported on alumina catalysts, CO oxidation follows a Langmuir-Hinshelwood mechanism, where O{sub 2} and CO compete in the adsorption on the same type of active sites. It is noteworthy that the addition of La{sub 2}O{sub 3} modifies the reaction mechanism. In this case, CO is not only adsorbed on the Pt active sites but also on La{sub 2}O{sub 3}, forming bridge bonded carbonates which leads to high reactivity at low temperatures. An increase on temperature produces CO desorption from Pt surface sites and favours oxygen adsorption producing CO{sub 2}. CO oxidation with surface hydroxyl groups was activated producing simultaneously CO{sub 2} and H{sub 2}. (author)

    Full Text Available Background: Due to high prevalence of infertility, increasing demand for infertility treatment, and provision of high quality of fertility care, it is necessary for healthcare professionals to explore infertile couples’ expectations and needs. Identification of these needs can be a prerequisite to plan the effective supportive interventions. The current study was, therefore, conducted in an attempt to explore and to understand infertile couples’ experiences and needs. Materials and Methods: This is a qualitative study based on a content analysis approach. The participants included 26 infertile couples (17 men and 26 women and 7 members of medical personnel (3 gynecologists and 4 midwives as the key informants. The infertile couples were selected from patients attending public and private infertility treatment centers and private offices of infertility specialists in Isfahan and Rasht, Iran, during 2012-2013. They were selected through purposive sampling method with maximum variation. In-depth unstructured interviews and field notes were used for data gathering among infertile couples. The data from medical personnel was collected through semi-structured interviews. The interview data were analyzed using conventional content analysis method. Results: Data analysis revealed four main categories of infertile couples’ needs, including: i. Infertility and social support, ii. Infertility and financial support, iii. Infertility and spiritual support and iv. Infertility and informational support. The main theme of all these categories was assistance and support. Conclusion: The study showed that in addition to treatment and medical needs, infertile couples encounter various challenges in different emotional, psychosocial, communicative, cognitive, spiritual, and economic aspects that can affect various areas of their life and lead to new concerns, problems, and demands. Thus, addressing infertile couples’ needs and expectations alongside their

    Iacuone, Leann

    Novice science teachers leave the confines of colleges and universities to embark on a new adventure in education where they aim to influence young minds, make a difference in the world, and share their love for their content. They have learned their pedagogical skills with the support and assistance of fellow classmates, a supporting professor, and a cooperating teacher. These teachers enter their new place of employment and are met with many unexpected challenges, such as a lack of resources, no one to ask questions of, and a busy staff with already established relationships, causing them to feel an overall lack of support and resulting in many new teachers rethinking their career choice and leaving the field of education within 5 years of entering. This multiple-case study investigated the administrative support 4 novice science teachers received during an academic year and the novice teachers' perceptions of the support they received to answer the following research question: How do novice science teachers who have consistent interactions with administrators develop during their first year? To answer this question, semistructured interviews, reflection journals, observations, resumes, long-range plans, and student discipline referrals were collected. The findings from this study show novice science teachers who had incidents occur in the classroom requiring administrative assistance and guidance felt more confident in enforcing their classroom management policies and procedures as the year progressed to change student behavior. The novice science teachers perceived administrators who provided resources including technology, office supplies, science supplies, and the guidance of a mentor as supportive. Novice science teachers who engaged in dialogue after administrative observations, were provided the opportunity to attend professional development outside the district, and had a mentor who taught the same discipline made more changes to their instructional

    This study investigates how faculty, student, and course features are linked to student outcomes in Learning Assistant (LA) supported courses. Over 4,500 students and 17 instructors from 13 LA Alliance member institutions participated in the study. Each participating student completed an online concept inventory at the start (pre) and end (post) of their term. The physics concept inventories included Force and Motion Concept Evaluation (FMCE) and the Brief Electricity and Magnetism Assessment (BEMA). Concepts inventories from the fields of biology and chemistry were also included. Our analyses utilize hierarchical linear models that nest student level data (e.g. pre/post scores and gender) within course level data (e.g. discipline and course enrollment) to build models that examine student outcomes across institutions and disciplines. We report findings on the connections between students' outcomes and their gender, race, and time spent working with LAs as well as instructors' experiences with LAs.

  9. Experimental Study on Shear Performance of Bolt in Roadway Supporting

    Directory of Open Access Journals (Sweden)

    D.J. Li

    2014-09-01

    Full Text Available The corner bolt is proved to be effective in the control of floor deformation of roadway, and the relevant studies on bolting mechanisms are of great significance in improving roadway stability. In this paper, two types of shear tests on six forms of bolts are performed by using self-designed shear test device, the electro-hydraulic servo triaxial testing system. The shear characteristics of different types of bolts are obtained. The results show that different bolt rods or different internal filling conditions result in large differences in shear resistance and different deformation adaptability. We find that the filling materials added can improve the shear performance of bolt significantly, and the bolt with steel not only can improve the strength of bolt body, but also has the bimodal characteristic that makes the bolt have the secondary bearing capacity and withstand larger deformation range during the process of shear, and shows a better support performance. Hoping to provide the experiment basis for support design and field application in the future.

    The need to reform ineffective or harmful public subsidies has long been recognised and has been a contentious point of discussion for several years. The EU has a long-standing commitment to removing or phasing out environmentally harmful subsidies (EHS). Most recently, the need to phase out EHS is reiterated in the 'Roadmap for a resource efficient Europe' which includes a milestone that 'by 2020 EHS will be phased out, with due regard to the impact on people in need'. Despite several commitments, progress has been slow and subsidies remain an issue in most EU countries. This study focuses specifically on EHS at the level of EU Member States; it identifies key types of EHS and examines cases of existing EHS across a range of environmental sectors and issues, including subsidies from non-action. The study also analyses examples of good practices in the reform of EHS in EU Member States and the lessons that can be learnt from these cases. Finally, based on this analysis, it develops practical recommendations on phasing out and reforming EHS to support the objectives of the Europe 2020 Strategy and the resource efficiency agenda. The study was carried out between January and October 2012 and is based on an analysis of literature and consultation with experts and policy makers. The sectoral cases studied are listed and discussed in the annexes report: agriculture, climate and energy, fisheries, food, forestry, materials, transport, waste, and water.

    Performing extravehicular activity (EVA) at various locations of the lunar surface presents thermal challenges that exceed those experienced in space flight to date. The lunar Portable Life Support System (PLSS) cooling unit must maintain thermal conditions within the space suit and reject heat loads generated by the crewmember and the PLSS equipment. The amount of cooling required varies based on the lunar location and terrain due to the heat transferred between the suit and its surroundings. A study has been completed which investigated the resources required to provide cooling under various lunar conditions, assuming three different thermal technology categories: 1. Spacesuit Water Membrane Evaporator (SWME) 2. Subcooled Phase Change Material (SPCM) 3. Radiators with and without heat pumps Results from the study are presented that show mass and power impacts on the cooling system as a function of the location and terrain on the lunar surface. Resources (cooling equipment mass and consumables) are greater at the equator and inside sunlit craters due to the additional heat loads on the cooling system. While radiator and SPCM technologies require minimal consumables, they come with carry-weight penalties and have limitations. A wider investigation is recommended to determine if these penalties and limitations are offset by the savings in consumables.

    To investigate the impact of rehabilitation measures on work ability and return to work (RTW), specifically the association between workplace rehabilitation/supportive conditions at work and work ability and RTW over time, among women on long-term sick leave. Questionnaire data were collected (baseline, 6 and 12 months) from a cohort of women (n = 324). Linear mixed models were used for longitudinal analysis of the repeated measurements of work ability index (WAI), work ability score and working degree. These analyses were performed with different models; the explanatory variables for each model were workplace rehabilitation, supportive conditions at work and time. The individuals provided with workplace rehabilitation and supportive conditions (e.g. influence at work, possibilities for development, degree of freedom at work, meaning of work, quality of leadership, social support, sense of community and work satisfaction) had significantly increased WAI and work ability score over time. These individuals scored higher work ability compared to those individuals having workplace rehabilitation without supportive conditions, or neither. Additionally, among the individuals provided with workplace rehabilitation and supportive conditions, working degree increased significantly more over time compared to those individuals with no workplace rehabilitation and no supportive conditions. The results highlight the importance of integrating workplace rehabilitation with supportive conditions at work in order to increase work ability and improve the RTW process for women on long-term sick leave.

    Full Text Available New catalytic materials, based on palladium immobilized in ionic liquid supported on alginate, were elaborated. Alginate was associated with gelatin for the immobilization of ionic liquids (ILs and the binding of palladium. These catalytic materials were designed in the form of highly porous monoliths (HPMs, in order to be used in a column reactor. The catalytic materials were tested for the hydrogenation of 4-nitroaniline (4-NA in the presence of formic acid as hydrogen donor. The different parameters for the elaboration of the catalytic materials were studied and their impact analyzed in terms of microstructures, palladium sorption properties and catalytic performances. The characteristics of the biopolymer (proportion of β-D-mannuronic acid (M and α-L-guluronic acid (G in the biopolymer defined by the M/G ratio, the concentration of the porogen agent, and the type of coagulating agent significantly influenced catalytic performances. The freezing temperature had a significant impact on structural properties, but hardly affected the catalytic rate. Cellulose fibers were incorporated as mechanical strengthener into the catalytic materials, and allowed to enhance mechanical properties and catalytic efficiency but required increasing the amount of hydrogen donor for catalysis.

    This research program is directed toward a more fundamental understanding of the effects of catalyst composition and structure on the catalytic properties of metal oxides. Metal oxide catalysts play an important role in many reactions bearing on the chemical aspects of energy processes. Metal oxides are the catalysts for water-gas shift reactions, methanol and higher alcohol synthesis, isosynthesis, selective catalytic reduction of nitric oxides, and oxidation of hydrocarbons. A key limitation to developing insight into how oxides function in catalytic reactions is in not having precise information of the surface composition under reaction conditions. To address this problem we have prepared oxide systems that can be used to study cation-cation effects and the role of bridging (-O-) and/or terminal (=O) surface oxygen anion ligands in a systematic fashion. Since many oxide catalyst systems involve mixtures of oxides, we selected a model system that would permit us to examine the role of each cation separately and in pairwise combinations. Organometallic molybdenum and tungsten complexes were proposed for use, to prepare model systems consisting of isolated monomeric cations, isolated monometallic dimers and isolated bimetallic dimers supported on silica and alumina. The monometallic and bimetallic dimers were to be used as models of more complex mixed- oxide catalysts. Our current program was to develop the systems and use them in model oxidation reactions.

    Results of experiments conducted to maximize the productivity of potatoes grown under controlled environmental conditions are discussed. A variety of parameters is examined which affect potato growth, specifically, photoperiod, light intensity, temperature, nitrogen nutrition, carbon dioxide concentration and culture techniques. These experiments were conducted using five different cultivars, Russet Burbank, Norchip, Superior, Kennebec and Norland. To achieve high productivity, three specific objectives were explored: (1) to develop effective cultural procedures, (2) to determine the most effective photoperiod and (3) to develop a mist culture system. It is felt that the productivity obtained in this study is below the maximum that can be obtained. High irradiance levels coupled with tuber-promoting conditions such as cooler temperatures, increased CO2 levels and lowered nitrogen concentrations should allow increases in tuber production. Tuberization appears to be accelerated by short daylengths although final yields are not increased. Mist culture techniques have not yet produced fully developed tubers. The use of supporting media and alteration of the nitrogen content of the mist solution are being explored as a way to allow tubers to develop to maturity.

    Platinum metal catalysts supported on silica gel and alumina were examined by wide-angle anomalous x-ray scattering at the Cornell High Energy Synchrotron Source. Complete removal of the support background features is achieved by this method, eliminating errors due to inaccurate background estimation. Platinum diffraction patterns from very-high-percentage metal-exposed catalysts were obtained for the first time, as well as from platinum supported on alumina. This technique is suitable for examining catalysts under working conditions and is superior to EXAFS for determinations of particle morphology and size distribution. 10 references, 8 figures.

    Performance modeling studies are a necessary and cost effective element of the IMHEX-MCFC stack commercialization. Technologix Corporation, in cooperation with M-C Power, has developed the algorithms and computer code for two of the models in addition to modifying the PSI model for applications specific to IMHEX fuel cell concept. Three performance models support the product development effort: a modified PSI model; a two-dimensional cross-flow cell model and a three-dimensional stack model. The sizing, number and location of the stack inter-coolers in a fuel cell stack are typical model application. Recently M-C Power modified its stack configuration to cross-flow. The cross-flow allows simplified repeat parts manufacturing and reduces the risk of gas crossover. The MCFC cross-flow model developed at M-C Power supports heat loss from the stack edges, variable fuel flow rate regions and variable oxidant flow rate regions (coupled with the optimization module) among other features. Extensive computational experiments were conducted in support of the cross-flow geometry development for the MCFC stack. The oxidant flow distribution optimization was used to mitigate the hardware temperature hot-spot typical for the cross-flow geometry. The hardware temperature hot-spot increases corrosion rate, electrolyte loss, and leads to deterioration of the long-term MCFC stack performance. Under the normal operating conditions, the maximum local temperature of the cell hardware should not exceed 960 K. The mathematical optimization software was applied to find the optimum flow distribution. The minimization of the maximum hardware temperature was defined as an optimization goal. The gas flow rate in each region was selected as independent variable subjected to optimization. In some cases the authors have also added a distance between the fuel inlet and the flow region divider to the list of independent variables. The total gas flow rates, inlet gas temperatures and compositions

    2003-01-01

    The tethered, chiral, chelating diphosphine rhodium complex, which catalyzes the enantioselective hydrogenation of methyl-α-acetamidocinnamate (MAC), has the illustrated structure as established by 31P NMR and IR studies. Spectral and catalytic investigations also suggest that the mechanism of action of the tethered complex is the same as that of the untethered complex in solution. The rhodium complexes, [Rh(COD)H]4, [Rh(COD)2]+BF4-, [Rh(COD)Cl]2, and RhCl3• 3H2O, adsorbed on SiO2 are optimally activated for toluene hydrogenation by pretreatment with H2 at 200 C. The same complexes on Pd-SiO2 are equally active without pretreatments. The active species in all cases is rhodium metal. The catalysts were characterized by XPS, TEM, DRIFTS, and mercury poisoning experiments. Rhodium on silica catalyzes the hydrogenation of fluorobenzene to produce predominantly fluorocyclohexane in heptane and 1,2-dichloroethane solvents. In heptane/methanol and heptane/water solvents, hydrodefluorination to benzene and subsequent hydrogenation to cyclohexane occurs exclusively. Benzene inhibits the hydrodefluorination of fluorobenzene. In DCE or heptane solvents, fluorocyclohexane reacts with hydrogen fluoride to form cyclohexene. Reaction conditions can be chosen to selectively yield fluorocyclohexane, cyclohexene, benzene, or cyclohexane. The oxorhenium(V) dithiolate catalyst [-S(CH2)3s-]Re(O)(Me)(PPh3) was modified by linking it to a tether that could be attached to a silica support. Spectroscopic investigation and catalytic oxidation reactivity showed the heterogenized catalyst's structure and reactivity to be similar to its homogeneous analog. However, the immobilized catalyst offered additional advantages of recyclability, extended stability, and increased resistance to deactivation.

    The subject of climate change holds tremendous opportunity for students to learn how scientists use data to develop and test theories of how the natural world works and appreciate how climate change instantiates cross-cutting NGSS science themes like stability and change, energy and matter, and cause and effect. To do so, students and teachers need help seeing in authentic Earth system data complex climate interactions and generate plans for building greater understanding of the complexities through further data investigation. With ever-growing repositories of global and regional public data and user friendly tools for their display, K-12 educators are challenged to help students study data independently rather than through the usual pre-filtered didactic presentations of data found in textbooks. The paper will describe strategies for facilitating critical thinking about authentic climate-related data in two climate change education projects funded by NASA and NSF, as well as learning outcomes. Data Enhanced Investigations for Climate Change Education (dicce.sri.com) brings data from NASA satellite missions to classrooms. Studying Topography, Orographic Rainfall, and Ecosystems with Geospatial Information Technology (store.sri.com) provides recent climatological and vegetation data about certain study areas in California and New York plus geospatially distributed projected values of temperature, precipitation, and land cover in 2050 and 2099, derived from NCAR's A2 climate change model. Supportive resources help students move from naïve conceptions of simple linear relationships between variables into critical analysis of what other variables could be mediating those relationships.

    We determined the need for changes in minute ventilation with adaptive support ventilation after percutaneous dilatational tracheotomy under endoscopic guidance in 34 intensive care unit patients. During the procedure, minute ventilation was not changed; only maximum pressure limits were adjusted, if necessary. After insertion of the tracheotomy, cannula minute ventilation was adjusted only if Paco(2)-values changed >or=0.5 kPa from baseline. In 74% of patients, adaptive support ventilation was unable to maintain minute ventilation during the use of the endoscope, mandating pressure limitation adjustments. In a minority of patients (26%), minute ventilation had to be adjusted to achieve similar Paco(2) values.

    1987-10-01

    This paper presents the results of numerous design studies carried out at Perkin-Elmer in support of the design of large diameter controllable mirrors for use in laser beam control, surveillance, and astronomy programs. The results include relationships between actuator location and spacing and the associated degree of correctability attainable for a variety of faceplate configurations subjected to typical disturbance environments. Normalizations and design curves obtained from closed-form equations based on thin shallow shell theory and computer based finite-element analyses are presented for use in preliminary design estimates of actuator count, faceplate structural properties, system performance prediction and weight assessments. The results of the analyses were obtained from a very wide range of mirror configurations, including both continuous and segmented mirror geometries. Typically, the designs consisted of a thin facesheet controlled by point force actuators which in turn were mounted on a structurally efficient base panel, or "reaction structure". The faceplate materials considered were fused silica, ULE fused silica, Zerodur, aluminum and beryllium. Thin solid faceplates as well as rib-reinforced cross-sections were treated, with a wide variation in thickness and/or rib patterns. The magnitude and spatial frequency distribution of the residual or uncorrected errors were related to the input error functions for mirrors of many different diameters and focal ratios. The error functions include simple sphere-to-sphere corrections, "parabolization" of spheres, and higher spatial frequency input error maps ranging from 0.5 to 7.5 cycles per diameter. The parameter which dominates all of the results obtained to date, is a structural descriptor of thin shell behavior called the characteristic length. This parameter is a function of the shell's radius of curvature, thickness, and Poisson's ratio of the material used. The value of this constant, in itself

    AIMS: This meta-analysis sought to identify which subgroups of clients with severe mental illness (SMI) benefited from evidence-based supported employment. METHODS: We used meta-analysis to pool the samples from 4 randomized controlled trials comparing the Individual Placement and Support (IPS) model of supported employment to well-regarded vocational approaches using stepwise models and brokered services. Meta-analysis was used to determine the magnitude of effects for IPS\\/control group differences within specific client subgroups (defined by 2 work history, 7 sociodemographic, and 8 clinical variables) on 3 competitive employment outcomes (obtaining a job, total weeks worked, and job tenure). RESULTS: The findings strongly favored IPS, with large effect sizes across all outcomes: 0.96 for job acquisition, 0.79 for total weeks worked, and 0.74 for job tenure. Overall, 90 (77%) of the 117 effect sizes calculated for the 39 subgroups exceeded 0.70, and all 117 favored IPS. CONCLUSIONS: IPS produces better competitive employment outcomes for persons with SMI than alternative vocational programs regardless of background demographic, clinical, and employment characteristics.

    The National Aeronautics and Space Administrations (NASA) technical developments for highly reliable life support systems aim to maximize the viability of long duration deep space missions. Among the life support system functions, airborne particulate matter filtration is a significant driver of launch mass because of the large geometry required to provide adequate filtration performance and because of the number of replacement filters needed to a sustain a mission. A trade analysis incorporating various launch, operational and maintenance parameters was conducted to investigate the trade-offs between the various particulate matter filtration configurations. In addition to typical launch parameters such as mass, volume and power, the amount of crew time dedicated to system maintenance becomes an increasingly crucial factor for long duration missions. The trade analysis evaluated these parameters for conventional particulate matter filtration technologies and a new multi-stage particulate matter filtration system under development by NASAs Glenn Research Center. The multi-stage filtration system features modular components that allow for physical configuration flexibility. Specifically, the filtration system components can be configured in distributed, centralized, and hybrid physical layouts that can result in considerable mass savings compared to conventional particulate matter filtration technologies. The trade analysis results are presented and implications for future transit and surface missions are discussed.

    Various research studies have identified the sources and types of support that people with cancer receive; however, few have focused on identifying the specific characteristics of emotional, instrumental, and informational support. In this study, focus groups consisting of Gilda's Club members explored the types of support that people with cancer and their caregivers experienced and valued. Results showed that although men and women with cancer and caregivers identify similar sources of support, they experience different types of support. Results also indicated a desire among participants to help and support others, a concept referred to as generativity. Implications for social workers and health care providers are explored.

    Science.gov (United States)

    Daigle, Matthew; Goebel, Kai

    2011-01-01

    Prognostics technologies determine the health (or damage) state of a component or sub-system, and make end of life (EOL) and remaining useful life (RUL) predictions. Such information enables system operators to make informed maintenance decisions and streamline operational and mission-level activities. We develop a model-based prognostics methodology for pneumatic valves used in ground support equipment for cryogenic propellant loading operations. These valves are used to control the flow of propellant, so failures may have a significant impact on launch availability. Therefore, correctly predicting when valves will fail enables timely maintenance that avoids launch delays and aborts. The approach utilizes mathematical models describing the underlying physics of valve degradation, and, employing the particle filtering algorithm for joint state-parameter estimation, determines the health state of the valve and the rate of damage progression, from which EOL and RUL predictions are made. We develop a prototype user interface for valve prognostics, and demonstrate the prognostics approach using historical pneumatic valve data from the Space Shuttle refueling system.

    The Idaho National Engineering and Environmental Laboratory is evaluating in situ bioremediation of contaminated groundwater at its Test Area North Facility. To determine feasibility, microcosm and bioreactor studies were conducted to ascertain the ability of indigenous microbes to convert trichloroethene and dichloroethene to non-hazardous byproducts under aerobic and anaerobic conditions, and to measure the kinetics of microbial reactions associated with the degradation process. Microcosms were established from core samples and groundwater obtained from within the contaminant plume. These microcosms were amended with nutrients, under aerobic and anaerobic conditions, to identify electron donors capable of stimulating the degradation process. Results of the anaerobic microcosm studies showed that lactate, acetate and propionate amendments stimulated indigenous cell growth and functioned as effective substrates for reductive degradation of chloroethenes. Bioreactors inoculated with cultures from these anaerobic microcosms were operated under a batch mode for 42 days then converted to a fed-batch mode and operated at a 53-day hydraulic residence time. It was demonstrated that indigenous microbes capable of complete anaerobic reductive dechlorination are present in the subject well. It was also demonstrated that aerobic microbes capable of oxidizing chlorinated compounds produced by anaerobic reductive dechlorination are present. Kinetic data suggest that controlling the type and concentration of electron donors can increase trichlorethene conversion rates. In the event that complete mineralization of trichlorethene does not occur following stimulation, and anaerobic/aerobic treatment scheme is feasible.

  20. Materials study supporting thermochemical hydrogen cycle sulfuric acid decomposer design

    Science.gov (United States)

    Peck, Michael S.

    Increasing global climate change has been driven by greenhouse gases emissions originating from the combustion of fossil fuels. Clean burning hydrogen has the potential to replace much of the fossil fuels used today reducing the amount of greenhouse gases released into the atmosphere. The sulfur iodine and hybrid sulfur thermochemical cycles coupled with high temperature heat from advanced nuclear reactors have shown promise for economical large-scale hydrogen fuel stock production. Both of these cycles employ a step to decompose sulfuric acid to sulfur dioxide. This decomposition step occurs at high temperatures in the range of 825°C to 926°C dependent on the catalysis used. Successful commercial implementation of these technologies is dependent upon the development of suitable materials for use in the highly corrosive environments created by the decomposition products. Boron treated diamond film was a potential candidate for use in decomposer process equipment based on earlier studies concluding good oxidation resistance at elevated temperatures. However, little information was available relating the interactions of diamond and diamond films with sulfuric acid at temperatures greater than 350°C. A laboratory scale sulfuric acid decomposer simulator was constructed at the Nuclear Science and Engineering Institute at the University of Missouri-Columbia. The simulator was capable of producing the temperatures and corrosive environments that process equipment would be exposed to for industrialization of the sulfur iodide or hybrid sulfur thermochemical cycles. A series of boron treated synthetic diamonds were tested in the simulator to determine corrosion resistances and suitability for use in thermochemical process equipment. These studies were performed at twenty four hour durations at temperatures between 600°C to 926°C. Other materials, including natural diamond, synthetic diamond treated with titanium, silicon carbide, quartz, aluminum nitride, and Inconel

    2013-07-01

    Rebaudioside D (Reb D) is one of the several glycosides found in the leaves of Stevia rebaudiana (Bertoni) Bertoni (Compositae) which has been identified as a potential sweetener. The metabolism of Reb A and Reb D was evaluated in various in vitro matrices (simulated gastrointestinal fluids, rat liver microsomes, and rat cecal contents) and through analysis of plasma collected from rats in a dietary toxicity study. Reb A and Reb D showed similar stability when exposed to simulated stomach and small intestine fluids, with susceptibility to hydrolytic degradation by enteric bacteria collected from the cecum. Incubations with rat liver microsomes indicated that neither compound is expected to be metabolized by the liver enzymes. Plasma concentrations of Reb D, Reb A, and/or the final hydrolysis product of each compound, free/conjugated steviol, were consistent between animals administered either Reb D or Reb A in the diet. A repeated exposure dietary toxicity study was conducted to compare the safety of Reb D, when administered at target exposure levels of 500, 1000, and 2000 mg/kg body weight (bw)/d to Sprague-Dawley rats for 28 days, to that of Reb A administered at a target exposure level of 2000 mg/kg bw/d. There were no treatment-related effects on the general condition and behavior of the animals and no toxicologically relevant, treatment-related effects on hematology, serum chemistry, or urinalysis. Macroscopic and microscopic findings revealed no treatment-related effects on any organ evaluated. Results were comparable between the group administered 2000 mg/kg/d Reb D and the group administered 2000 mg/kg/d Reb A.

    A comparative study of logistic regression, support vector machine (SVM) and least square support vector machine (LSSVM) models has been done to predict the slope failure (landslide) along East-West Highway (Gerik-Jeli). The effects of two monsoon seasons (southwest and northeast) that occur in Malaysia are considered in this study. Two related factors of occurrence of slope failure are included in this study: rainfall and underground water. For each method, two predictive models are constructed, namely SOUTHWEST and NORTHEAST models. Based on the results obtained from logistic regression models, two factors (rainfall and underground water level) contribute to the occurrence of slope failure. The accuracies of the three statistical models for two monsoon seasons are verified by using Relative Operating Characteristics curves. The validation results showed that all models produced prediction of high accuracy. For the results of SVM and LSSVM, the models using RBF kernel showed better prediction compared to the models using linear kernel. The comparative results showed that, for SOUTHWEST models, three statistical models have relatively similar performance. For NORTHEAST models, logistic regression has the best predictive efficiency whereas the SVM model has the second best predictive efficiency.

    The present study examined how support providers' empathic dispositions (dispositional perspective taking, empathic concern, and personal distress) as well as their situational empathic reactions (interaction-based perspective taking, empathic concern, and personal distress) relate to the provision of spousal support during observed support interactions. Forty-five committed couples provided questionnaire data and participated in two ten-minute social support interactions designed to assess behaviors when partners are offering and soliciting social support. A video-review task was used to assess situational forms of perspective taking (e.g., empathic accuracy), empathic concern and personal distress. Data were analyzed by means of the multi-level Actor-Partner Interdependence Model. Results revealed that providers scoring higher on affective empathy (i.e., dispositional empathic concern), provided lower levels of negative support. In addition, for male partners, scoring higher on cognitive empathy (i.e., situational perspective taking) was related to lower levels of negative support provision. For both partners, higher scores on cognitive empathy (i.e., situational perspective taking) correlated with more instrumental support provision. Male providers scoring higher on affective empathy (i.e., situational personal distress) provided higher levels of instrumental support. Dispositional perspective taking was related to higher scores on emotional support provision for male providers. The current study furthers our insight into the empathy-support link, by revealing differential effects (a) for men and women, (b) of both cognitive and affective empathy, and

Social support is a major determinant of health. The objective of this study was to determine the perceived social support and its associated sociodemographic factors among women of reproductive age. Methods This was a population-based cross-sectional study with multistage random cluster sampling of 1359 women of reproductive age. Data were collected using questionnaires on sociodemographic factors and perceived social support (PRQ85-Part 2). The relationship between the dependent variable (perceived social support) and the independent variables (sociodemographic characteristics) was analyzed using the multivariable linear regression model. Results The mean score of social support was 134.3 ± 17.9. Women scored highest in the “worth” dimension and lowest in the “social integration” dimension. Multivariable linear regression analysis indicated that the variables of education, spouse’s occupation, Sufficiency of income for expenses and primary support source were significantly related to the perceived social support. Conclusion Sociodemographic factors affect social support and could be considered in planning interventions to improve social support for Iranian women. PMID:22988834

    2015-01-01

    This qualitative study explored patients' experiences of nurse support for an Internet-delivered weight management intervention. Eighteen patients who had received either basic or regular nurse support (three or seven contacts, respectively) for the Internet intervention were interviewed. The data were analysed using thematic analysis. The findings suggest that more regular support for Internet interventions may have the potential to inhibit the development of autonomous motivation for weight loss, which might lead to problems in sustaining losses after support ends. Further research is now needed to confirm whether motivation is influenced by frequency of nurse support in Internet interventions in order to inform the development of optimal support which promotes sustained weight loss.

  20. Silicalite-1 zeolite membranes on unmodified and modified surfaces of ceramic supports: A comparative study

    M K Naskar; D Kundu; M Chatterjee

    2009-10-01

    Silicalite-1 zeolite membranes were prepared hydrothermally on the porous ceramic supports, both unmodified and modified with 3-aminopropyl triethoxysilane (APTES) as a coupling agent following ex situ (secondary) crystal growth process. The microstructure of the membranes was examined by scanning electron microscopy (SEM). The permeation study with a single gas, nitrogen (N2) was performed through the membranes. For the surface modified support, a more surface coverage of the seed crystals on the porous support was observed resulting in a relatively higher dense packing of the crystals during secondary crystal growth process compared to that obtained from the unmodified support. The membrane developed on surface modified support rendered lower permeance value i.e. 9 × 10-7 mol m-2 s-1 Pa-1 of N2 compared to that formed on the unmodified support which gave permeance value of 20 × 10-7 mol m-2 s-1 Pa-1 of N2.

    Liedgren, Pernilla; Elvhage, Gudrun; Ehrenberg, Anna; Kullberg, Christian

    2016-01-01

    Decision support systems are known to be helpful for professionals in many medical professions. In social work, decision support systems have had modest use, accompanied by strong criticism from the profession but often by praise from political management. In this study the aim of the authors was to collect and report on the published evidence on decision support systems in social work. The conclusion of the authors is that a decision support system gives support to social workers in conducting a thorough investigation, but at the same time gives them the freedom to make autonomous decisions that might be the most helpful for and used by social workers. Their results also indicate that decision support systems focusing on atypical rather than typical cases are perceived as the most useful among experienced staff.

    This multi-study analysis systematically examines research findings on relationships between social support and caregiver adjustment to discover whether informal support helps family caregivers. Caring for older relatives is an ongoing stressful life course event and role. Informal social support is often used as a predictor of caregiver adjustment outcomes. It is widely believed to enhance adjustment. Yet the varied research results do not necessarily support this belief. A computer-generated literature search of social sciences and medical databases produced thirty-five caregiving articles, published in refereed journals, which meet study parameters. A coding form was developed to categorize social support and adjustment variables for cross-tabular analyses. The findings show most relationships (61%) between social support and caregiver adjustment are not positively significant. Of the minority of positively significant relationships, neither perceived (available) nor received support is more important and neither instrumental nor socioemotional support is more likely to aid adjustment. Researchers and health care professionals need to explore the negative impact of social support and attributes of caregiver-care recipient relationships.

    Self-management support is an integral part of current chronic care guidelines. The success of self-management interventions varies between individual patients, suggesting a need for tailored self-management support. Understanding the role of patient factors in the current decision making of health professionals can support future tailoring of self-management interventions. The aim of this study is to identify the relative importance of patient factors in health professionals' decision making regarding self-management support. A factorial survey was presented to primary care physicians and nurses. The survey consisted of clinical vignettes (case descriptions), in which 11 patient factors were systematically varied. Each care provider received a set of 12 vignettes. For each vignette, they decided whether they would give this patient self-management support and whether they expected this support to be successful. The associations between respondent decisions and patient factors were explored using ordered logit regression. The survey was completed by 60 general practitioners and 80 nurses. Self-management support was unlikely to be provided in a third of the vignettes. The most important patient factor in the decision to provide self-management support as well as in the expectation that self-management support would be successful was motivation, followed by patient-provider relationship and illness perception. Other factors, such as depression or anxiety, education level, self-efficacy and social support, had a small impact on decisions. Disease, disease severity, knowledge of disease, and age were relatively unimportant factors. This is the first study to explore the relative importance of patient factors in decision making and the expectations regarding the provision of self-management support to chronic disease patients. By far, the most important factor considered was patient's motivation; unmotivated patients were less likely to receive self-management support

    Full Text Available Introduction: Nutritional support generates complications that must be detected and treated on time. Objective: To estimate the incidence of some complications of nutritional support in patients admitted to general hospital wards who received nutritional support in six high-complexity institutions. Methods: Prospective, descriptive and multicentric study in patients with nutritional support; the variables studied were medical diagnosis, nutritional condition, nutritional support duration, approach, kind of formula, and eight complications. Results: A total of 277 patients were evaluated; 83% received enteral nutrition and 17% received parenteral nutrition. Some 69.3% presented risk of malnourishment or severe malnourishment at admittance. About 35.4% of those receiving enteral nutrition and 39.6% of the ones who received parenteral nutrition had complications; no significant difference per support was found (p = 0.363. For the enteral nutrition, the most significant complication was the removal of the catheter (14%, followed by diarrhea (8.3%; an association between the duration of the enteral support with diarrhea, constipation and removal of the catheter was found (p < 0.05. For parenteral nutrition, hyperglycemia was the complication of highest inci­dence (22.9%, followed by hypophosphatemia (12.5%; all complications were associated with the duration of the support (p < 0.05. Nutritional support was suspended in 24.2% of the patients. Conclusions: Complications with nutritional support in hospital-ward patients were frequent, with the removal of the catheter and hyperglycemia showing the highest incidence. Duration of the support was the variable that revealed an asso­ciation with complications. Strict application of protocols could decrease the risk for complications and boost nutritional support benefits.

    In universities where significant numbers of nursing students come from non-traditional backgrounds, and where an equally significant proportion of students have English as a second language, provision of learning support is essential to ensure success and progression, and to prevent attrition. This paper presents an evaluative study of the support services provided to undergraduate nursing students in two universities in the United Kingdom (UK). Both universities have significant numbers of students from non-traditional backgrounds and who have English as a second language, and both institutions have in place a large array of student support mechanisms. The aims of the study were to identify all existing student support mechanisms across the two universities, to illuminate the profile of students who enter pre-registration programmes at the two universities (age, gender, educational background) and to measure the perceptions of students of the use and usefulness of the support mechanisms provided by their university. Survey method evaluative research was the chosen research approach. Findings showed that the support services that appear to have the greatest impact on student success in their nursing programme are the programme leaders/module teachers, small study skills groups (known as APPL and L2L) and, for the 50% of students who required it, academic literacy and numeracy support sessions. For students who have English as a second language and with non-traditional entry qualifications, numeracy and academic literacy support is particularly valued.

    Full Text Available Recognizing the conditions that minimize the impact of maternal depression on children has clinical relevance. The present review aimed to analyze recent empirical studies that have investigated the associations between maternal depression and different social support conditions for school-aged children. We systematically reviewed empirical articles indexed from 2007 to 2014 in the following databases: MEDLINE, PubMed, PsycINFO, Web of Science, LILACS and SciELO. Three keywords were used: maternal depression, social support and child behavior. Twenty-seven articles were included and analyzed. These studies included a broad range of contextual risk factors and social support conditions, and in their predictive models, it was found that less contextual risk and greater parental resources and social support were predictors of fewer problems for the children. The identification of social support sources that attenuate the effect of maternal depression on child outcomes has implications for the development of prevention and intervention programs.

    It is widely recognized that support is critical to graduate nurse transition from novice to advanced beginner-level practitioner and to the integration of neophyte practitioners into safe and effective organizational processes. Just what constitutes support, however, and why (if at all) support is important, when, ideally, support should be given, by whom, how, and for how long, have not been systematically investigated. Building on the findings (previously reported) of a year long study that had, as its focus, an exploration and description of processes influencing the successful integration of new graduate nurses into safe and effective organizational processes and systems, the findings presented in this article strongly suggest that support is critical to the process of graduate nurse transition, and that integration into "the system" is best provided during the first 4 weeks of a graduate nurse transition program and thereafter at the beginning of each ward rotation; that "informal teachers" and the graduate nurses themselves are often the best sources of support; and that the most potent barriers to support being provided are the untoward attitudes of staff toward new graduates. Drawing on the overall findings of the study, a new operational definition of support is proposed and recommendations are made for future comparative research on the issue.

    For Veterans managing PTSD symptoms, returning to vocational functioning is often challenging; identifying modifiable variables that can contribute to positive vocational adjustment is critical to improved vocational rehabilitation services. Workplace social support has proven to be important in vocational adjustment in both general population and vocational rehabilitation samples, but this area of inquiry has received little attention among Veterans with PTSD symptoms. In this small correlational study, employed Veterans (N = 63) presenting for outpatient PTSD treatment at a VA Health Care System completed surveys assessing demographic variables, PTSD symptoms, workplace social support, and job satisfaction. Workplace social support contributed to the prediction of job satisfaction. It is of note that workplace social support predicted a larger proportion of the variance in employment satisfaction than PTSD symptoms. Further research on workplace social support as a vocational rehabilitation resource for Veterans with PTSD is indicated.

    Full Text Available There is evidence that social support is important for the development and mainte- nance of body image satisfaction for people who have sustained burn injuries. This qualitative study explored the specific mechanisms by which social support impacts the body image satisfaction of burn survivors, drawing on nine participants’ in depth accounts. Participants were recruited through a burns unit at a public hospital in South Australia. Interviews were conducted with nine female burn survivors aged between 24 and 65 (mean age 44.6. Participants described their perceptions about their appearance post burn and their social support experiences. Four themes were identified: acceptance, social comparison, talking about appearance concerns, and the gaze of others. Results indicate that for these participants, social support was an important factor in coming to terms with changes in appearance, specifically support that helps to minimise feelings of difference. Unhelpful aspects of social support were also identified included feeling that suffering was being dismissed and resenting the perceived expectation from supports to be positive. Social supports are important to consider in relation to body image for those working with people who have survived burn injuries.

    This cross-sectional study aims to explore the relationship between different types and sources of social support and psychological distress by age and sex among survivors living in temporary housing 10 months after the Great East Japan Earthquake. Self-reported questionnaires/structured interviews administered from January to March 2012 recorded demographic characteristics, damage involving participants' families, social support, and psychological distress. Data on 296 participants aged 20 years or more from nine temporary housing complexes in Otsuchi were analyzed; K6 scores indicating psychological distress averaged 5.1 (standard deviation, 5.9; range, 0-24). Multiple logistic regression analyses indicated differences among types and sources of social support with regard to psychological distress by age and sex among disaster survivors. For men aged less than 65 years, social support by family was related to lower psychological distress. For women aged 65 years or more, emotional support from family, informational and instrumental support, and social companionship from friends in their own temporary housing complexes were related to less psychological distress. Differences in age and sex were related to different sources of social support in relation to psychological distress. It is necessary to pay more attention to those who lost family members in the disaster, especially men aged less than 65 years. It may also be necessary to support survivors in making friends when they relocate to temporary housing, especially women aged 65 years or more. © 2015 The Authors.

    Objective To explore how doula support influences women’s experiences with first-trimester surgical abortion. Study Design We conducted semi-structured interviews with women given the option to receive doula support during first-trimester surgical abortion in a clinic that uses local anesthesia and does not routinely allow support people to be present during procedures. Dimensions explored included: (1) reasons women did or did not choose doula support; (2) key aspects of the doula interaction; (3) future directions for doula support in abortion care. Interviews were transcribed and computer-assisted content analysis was performed; salient themes are presented. Results Thirty women were interviewed: 19 received and 11 did not receive doula support. Reasons to accept doula support included: (1) wanting companionship during the procedure; (2) being concerned about the procedure. Reasons to decline doula support included (1) a sense of stoicism and desiring privacy; or (2) not wanting to add emotion to this event. Women who received doula support universally reported positive experiences with the verbal and physical techniques used by doulas during the procedure and most women who declined doula support subsequently regretted not having a doula. Many women endorsed additional roles for doulas in abortion care, including addressing informational and emotional needs before and after the procedure. Conclusion Women receiving first-trimester surgical abortion in this setting value doula support at the time of the procedure. This intervention has the potential to be further developed to help women address pre- and post-abortion informational and emotional needs. Implications In a setting that does not allow family or friends to be present during the abortion procedure, women highly valued the presence of trained abortion doulas. This study speaks to the importance of providing support to women during abortion care. Developing a volunteer doula service is one approach to

    We hypothesised that a key factor determining the quality of active support was 'practice leadership' - provided by the first-line manager to focus staff attention and develop staff skills in providing direct support to enable people with intellectual disabilities to have a good quality of life. This exploratory study focused on what levels of practice leadership were found and its role in explaining variation in active support. Relevant aspects of management, including practice leadership, were assessed by questionnaires administered to staff in residential settings alongside observational measures of active support and resident engagement in meaningful activity. Relationships between these variables were explored using regression and post hoc group comparisons. There was wide variation, with average levels of practice leadership being low, though improving over the period studied. Practice leadership had a significant impact on active support, but was fully mediated by the effect of quality of management. When the quality of management was higher better practice leadership did produce a significant difference in active support. However, higher quality of management on its own did not produce better active support. A number of limitations are acknowledged and further research is required. Practice leadership appears to be an important factor in enabling staff to provide active support but as part of generally good management. Given the rather low levels found, attention needs to be given to the training, career development and support of practice leaders and also to how to protect their time from their many other responsibilities. © 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    In this paper, adsorption properties of dibenzothiophene (DBT) on carbon nanotube, carbon nanotube supported oxide state and sulfide state CoMo catalysts are studied by using thermal gravimetric analysis (TGA) technique and FT-IR spectroscopy. Activated carbon support, γ-Al2O3 support and supported CoMo catalysts are also subjected to studies for comparison. It was found that sulfide state CoMoS/MWCNT, CoMoS/AC and CoMoS/γ-Al2O3 catalysts adsorbed much more DBT molecules than their corresponding oxide state catalysts, as well as their corresponding supports. The chemically adsorbed DBT aromatic molecules did not undergo decomposition on the surface of supports, supported oxide state CoMo catalysts and sulfide state CoMo catalysts when out-gassing at 373 K. FT-IR results indicated that DBT molecules mainly stand upright on the active sites (acid sites and/or transition active phases) of CoMoS/MWCNT catalyst. However, DBT aromatic molecules mainly lie flat on MWCNT and CoMoO/MWCNT.

    Full Text Available Cognitive remediation (CR is a treatment approach that is being increasingly examined as a means through which the cognitive impacts of schizophrenia might be ameliorated. While CR has demonstrated good outcomes when paired with supported employment, little is known regarding how it might be integrated within supported education contexts. In this study CR was examined in a supported education context with 16 individuals with psychosis. The findings indicated that CR aligned well with the academic curriculum with very low attrition, was found useful by students, and showed similar pre-post differences on cognitive measures as those found in previous work.

    Full Text Available The main objective of this study was the evaluation of biofilm formation onto different supports and of biofilm efficiency to treat wastewater. Two different reactors were used, one with porous polyvinyl alcohol gel (PVA biocarrier and another with a high-density polyethylene (PE biocarrier. The reactor performance was evaluated and the biofilm formed was analyzed with potentiometric mass titrations. The biofilm formation was monitored with diffuse reflectance spectroscopy. The presence of the support did not alter the nature of the biofilm. However, the quantity of the biofilm formed was higher when polar surface groups were present on the support.

    The amount of customisation to an enterprise resource planning (ERP) system has always been a major concern in the context of the implementation. This article focuses on the phase of maintenance and presents an empirical study about the relationship between the amount of customising and the resulting support effort. We establish a structural equation modelling model that explains support effort using customisation effort, organisational characteristics and scope of implementation. The findings using data from an ERP provider show that there is a statistically significant effect: with an increasing amount of customisation, the quantity of telephone calls to support increases, as well as the duration of each call.

    Full Text Available The globalization has increased the importance of research and development (R&D activity and of technological advancements, especially in information and communication technologies. This case is valid for small and medium-sized enterprises (SMEs which have taken a crucial place in all economies. Since R&D activities have high costs and public features, these activities cannot be carried out by firm, especially SMEs’ fiscal sources. Direct supports play a key-role in most countries. In related literature, many researchers have stressed that direct public supports towards R&D activities are important for SMEs. Recently, the requirement of public support in R&D activities has been increased in Turkey, just as in most countries. The study investigated both the relationship between direct public supports and R&D in SMEs and the factors determining the using level of R&D supports with an empirical study for Turkey as a sample. A survey of 600 SMEs in Turkey was conducted by a research company on behalf of the authors. The survey data have been estimated by logistic regression analysis and allow us to indicate the factors which determine the using level of direct public supports of SMEs. According to the logistic regression model, the determiner factors are the information level of firms on R&D supports, available convenient support kind, the number of licenses and patents, supply of new product to market etc., in order to increase the possibility for benefit from supports. The most important factor is the fact that SMEs obtain licenses and patents. These results provide contribution to improving R&D activities in SMEs.

    Full Text Available The use of Information and Communication Technologies can be seen as an important factor for social inclusion in its different aspects - economic, social, relational and informational, among others. Inclusion potentiality is even more relevant for groups of people who face limiting life conditions which determine social barriers. This study investigated the social support offered to people with disabilities based on the social network analysis method. The research objective was to make the online support dynamics for low vision people, friends and relatives evident, having as case study the Facebook Low Vision group. The social network modelling and quantitative analysis were performed from user data collection, posts, comments and likes. Contents were classified according to the type of support (Emotional or Instrumental and according to its intention (Offered or Requested, represented in graphs as indicators for analysis. Results pointed towards a larger use rate of Instrumental and Offered support although a more intense and comprehensive exchange of Emotional and Requested support was found. Data collection limitations indicate the need for more empirical studies on the social use of socio-technical networks for different types of social support. This theme points to a research agenda about the role of information and communication technologies as a possible condition for inclusion, life quality and well-being of people with disabilities.

    A vegetative state (VS) is the probable result after brain damage. After VS patients are discharged from the hospital, the responsibility of caring of them is transferred to their families, which impacts a caregiver's physical and psychological health. Social support as a valuable resource reduces the negative effects of stressful events. This study aimed to explore the perception of social support among family caregivers of VS patients. This study is a part of a larger qualitative study which used the descriptive and qualitative method. Purposeful and theoretical sampling was done, and data was gathered through face-to-face, in-depth interviews. The four categories of "Family, a supporter in all aspects," "Beautiful emanation of the nurse's role," "Revitalization via empathy and companionship," and "Defects in support," were extracted. The primary concern of participants was receiving social support which can facilitate caregiving and coping with difficulties, but there are many shortcomings in supporting these caregivers.

    As the United States plans to return astronauts to the moon and eventually to Mars, designing the most effective, efficient, and robust space suit life support system that will operate successfully in these dusty environments is vital. There is some knowledge of the contaminants and level of infiltration expected from the Lunar and Mars dust, however risk mitigation strategies and filtration designs to prevent contamination within the space suit life support system are still undefined. A trade study was initiated to identify and address these concerns, and to develop new requirements for the Constellation Space Suit Element (CSSE) Portable Life Support System (PLSS). This trade study investigates historical methods of particulate contamination control in space suits and vehicles, and evaluated the possibility of using commercial technologies for this application. In addition, the trade study examined potential filtration designs. This paper summarizes the results of this trade study.

    This article presents results of several studies in Middle, Eastern and Southeastern Europe on needs and application areas, desirable attributes and marketing potentials of forest management support tools. By comparing present and future application areas, a trend from sectoral planning towards landscape planning and integration of multiple stakeholder needs is emerging. In terms of conflicts, where management support tools might provide benefit, no clear tendencies were found, neither on local nor on regional level. In contrast, on national and European levels, support of the implementation of laws, directives, and regulations was found to be of highest importance. Following the user-requirements analysis, electronic tools supporting communication are preferred against paper-based instruments. The users identified most important attributes of optimized management support tools: (i) a broad accessibility for all users at any time should be guaranteed, (ii) the possibility to integrate iteratively experiences from case studies and from regional experts into the knowledge base (learning system) should be given, and (iii) a self-explanatory user interface is demanded, which is also suitable for users rather inexperienced with electronic tools. However, a market potential analysis revealed that the willingness to pay for management tools is very limited, although the participants specified realistic ranges of maximal amounts of money, which would be invested if the products were suitable and payment inevitable. To bridge the discrepancy between unwillingness to pay and the need to use management support tools, optimized financing or cooperation models between practice and science must be found.

    The donor countries need to make decisions on various steps such as whether to fully accept newcomers’ requests, the depth of support, and how the supportive action will be carried out. Such is not an easy task due to limited time, resources, manpower, etc. Thus, creating an infrastructure to support emerging nuclear energy countries is needed. This paper suggests the resource portfolio concept used in business management and aims to analyze the validity of supporting the new entrants’ development of regulatory infrastructure as a case study. This study tries to develop a very simple Excel-based tool for assessing the supporting strategy quantitatively and screening the activities that is projected to be less effective and attractive. There are many countries, so called newcomers, which have expressed interests in developing their own nuclear power program. It has been recognized by the international community that every country considering embarking upon their own nuclear power program should establish their nuclear safety infrastructure to sustain a high level of nuclear safety. The newcomers have requested for considerable assistance from the IAEA and they already have bilateral cooperation programs with the advanced countries with matured nuclear regulatory programs. Currently, the regulatory bodies that provide support are confronted with two responsibilities as follows; the primary objective of the regulatory bodies is to ensure that the operator fulfills the responsibility to protect human health.

    This prospective study was designed to investigate the influence of high students' perceived teacher autonomy support in mandatory physical education on their intention and actual enrollment in elective physical education. Participants included 545 ninth-grade students enrolled in three suburban high schools in a major midwestern metropolitan area. A series of hypothesized models related to autonomy support within the Theory of Planned Behavior were tested. Structural equation modeling results demonstrated that perceived autonomy support provided by teachers in mandatory physical education could predict elective physical education enrollment indirectly via the mediation of attitudes and intention in the Theory of Planned Behavior Providing support for students' autonomy in physical education may hold potential promise for enhancing their future physical activity engagement.

    Full Text Available To obtain glucose biosensors based on glucose oxidase (GOx, the enzyme can be immobilized on the sensitive surface of a glass electrode by different techniques: deposition on membranous support (cellophane or other macromolecular material or entrapment in a matrix. Deposition on membranous support also involves cross-linking with glutaraldehyde or entrapment in silica gel, following the sol-gel procedure. The aim of this preliminary work was to study the influence of cellophane replacement with a PVA based membranous support on the glucose biosensor performance. The data obtained at pH measurements of buffer solutions with cellophane and PVA membranous supports respectively, show that the PVA based membrane assures superior performances of the biosensor for low glucose concentrations determination (about 10-4 M. These results allow the transition to an improved immobilization technique, namely the enzyme entrapment in membranous material.

    In this exploratory and descriptive research, we identified the meaning of religion and spirituality in the experience of patients at a public health service for treatment of HIV/AIDS in a Brazilian upcountry town. Eight participants were selected through theoretical sampling. Data were collected through semistructured interviews, and analyzed by means of qualitative content analysis. The emerging themes were religion: a path to support, and God is everything. Religion, as a path that leads patients to different sources of support, included exploration of different churches, acknowledgment of guilt, and finding strength to cope with the disease, rationalization of the disease process, meeting other churchgoers, and finding God and faith. God, an important source of support, was present in prayers, in the belief in healing through faith, and in the feeling of comfort and relief. Because spirituality and religion were seen as important sources of support, in this study we that health professionals include these aspects in care planning.

    Introduction: Newly graduated nurses experience many stressful situations during transition to practice. The provision of emotional support from more experienced nurses can ameliorate such work-related tension. Studies have not clearly specified the means through which such support could be most effectively provided; therefore the present study was conducted to explore the experiences of qualified nurses around the provision of emotional support to newly graduated nurses. Methods: This qualitative study was conducted through semi-structured interviews with 18 qualified nurses. A purposive sampling approach was used for selection of participants. Interviews were transcribed verbatim and analyzed by the conventional content analysis method. The study took place from 2014-2015 in six teaching hospitals in the northwest of Iran. Results: Emotional supports emerged in four following main-categories: Assurance, creating a sense of relaxation and security, lifting spirits, and emotional belonging and involvement. Conclusion: These results can help to establish an effective source of emotional support for newly graduated nurses. This can play an important role in reducing their stress and anxiety, in increasing their self-confidence and in forming a constructive relationship between them and qualified nurses. PMID:26989662

    During the last few years, manikin simulations have been used for cardiac life support training procedures in medical and nursing education. However, some nursing students have experienced attending real events involving cardiac life support during their clinical practice. This study aims to describe the meaning of experience of Thai nursing students when attending real situations of cardiac life support. A hermeneutic phenomenological study was used. Third and fourth year bachelor of nursing students at a university in the southern region of Thailand who had the experience of attending real situation of cardiac life support were purposely selected as the informants. The data were generated from individual in-depth interviews with eighteen nursing students. Van Manen's approach was used to analyze the data. Trustworthiness was established using the criteria set out by Lincoln and Guba. Essential themes situated in the context of the four existential grounds of body, time, space, and relation emerged. These were: being worried and fearful while desiring to participate in cardiac life support procedures; enhancing self value; knowing each moment is meaningful for one's life; having time to understand the reality of life; being in a small corner; appreciating such opportunities and the encouragement given by nurses and the healthcare team; and feeling empathy. Besides learning in classrooms and practicing in labs, experiencing real situations is beneficial for nursing students in learning cardiac life support. This study provides information that can be used for clinical teaching management in the topics relating to cardiac life support. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Several risk factors for negative birth experience have been identified, but little is known regarding the influence of social and midwifery support on the birth experience over time. The aim of this study was to describe women's birth experience up to two years after birth and to detect the predictive role of satisfaction with social and midwifery support in the birth experience. A longitudinal cohort study was conducted with a convenience sample of pregnant women from 26 community health care centres. Data was gathered using questionnaires at 11-16 weeks of pregnancy (T1, n=1111), at five to six months (T2, n=765), and at 18-24 months after birth (T3, n=657). Data about sociodemographic factors, reproductive history, birth outcomes, social and midwifery support, depressive symptoms, and birth experience were collected. The predictive role of midwifery support in the birth experience was examined using binary logistic regression. The prevalence of negative birth experience was 5% at T2 and 5.7% at T3. Women who were not satisfied with midwifery support during pregnancy and birth were more likely to have negative birth experience at T2 than women who were satisfied with midwifery support. Operative birth, perception of prolonged birth and being a student predicted negative birth experience at both T2 and T3. Perception of negative birth experience was relatively consistent during the study period and the role of support from midwives during pregnancy and birth had a significant impact on women's perception of birth experience.

    Full Text Available Background: Heart failure as a chronic disease poses many challenges for a patient in his or her everyday life. Support in various aspects of life positively affects coping strategies and influences the well-being and health outcomes of heart failure patients. Inadequate support may lead to a worsening of symptoms, increased hospital readmissions, psychological disorders, and a reduced quality of life. Objective: This study explored obstacles to coping related to support for heart failure patients as viewed by the patients themselves and their family members and caregivers. Design: This qualitative study was conducted using content analysis. The 20 Iranian participants included 11 patients with heart failure, three cardiologists, three nurses, and three family members of heart failure patients selected through purposive sampling. Data were collected through semi-structured interviews and analyzed using the Lundman and Graneheim qualitative content analysis method. Results: During data analysis, ‘defective support network’ developed as the main theme along with four other categories of ‘inadequate family performance’, ‘inadequate support by the healthcare team’, ‘distorted societal social support’, and ‘inadequate welfare support’. Conclusion: The findings of the current study can assist health authorities and planners in identifying the needs of patients with heart failure so as to focus and plan on facilitating their coping as much as possible by obviating the existing obstacles.

  5. Using a pneumatic support to correct sitting posture for prolonged periods: a study using airline seats.

    2009-09-01

    Prolonged sitting with spine flexion has been linked to low back disorders. A variety of mechanisms account for this based on biomechanical and neurological variables. Airline seats typically cause pronounced lumbar flexion due to their hollowed seat back design. A pneumatic support, placed between the seat back and the lumbar spine, was tested to see if lumbar flexion was reduced. Results showed that when the seats were positioned in the upright position, 15 of 20 participants experienced reduced lumbar flexion (by 15 degrees on average) with the support. The study was repeated on the five non-responders with the seatback set in the reclined position. This resulted in another four experiencing less lumbar flexion. Since seated flexion is associated with disc stress, reducing flexion with the support reduced lumbar stress. Spine flexion that results from prolonged sitting is associated with disc stress and pain. The pneumatic support tested here reduced spine flexion. While it is not known why airline seats are designed with no lumbar support, which causes excessive lumbar flexion while seated, the pneumatic support corrected this deficit. Reclining the seatback enhanced this effect.

    Inappropriate prescribing increases patient illness and death owing to adverse drug events. The inclusion of genetic information into primary care medication practices is one solution. Our aim was to assess the ability to obtain and genotype saliva samples and to determine the levels of use of a decision support tool that creates medication options adjusted for patient characteristics, drug-drug interactions and pharmacogenetics. We conducted a cohort study in 6 primary care settings (5 family practices and 1 pharmacy), enrolling 191 adults with at least 1 of 10 common diseases. Saliva samples were obtained in the physician's office or pharmacy and sent to our laboratory, where DNA was extracted and genotyped and reports were generated. The reports were sent directly to the family physician/pharmacist and linked to an evidence-based prescribing decision support system. The primary outcome was ability to obtain and genotype samples. The secondary outcomes were yield and purity of DNA samples, ability to link results to decision support software and use of the decision support software. Genotyping resulted in linking of 189 patients (99%) with pharmacogenetic reports to the decision support program. A total of 96.8% of samples had at least 1 actionable genotype for medications included in the decision support system. The medication support system was used by the physicians and pharmacists 236 times over 3 months. Physicians and pharmacists can collect saliva samples of sufficient quantity and quality for DNA extraction, purification and genotyping. A clinical decision support system with integrated data from pharmacogenetic tests may enable personalized prescribing within primary care. Trial registration: ClinicalTrials.gov, NCT02383290.

    The study examined the influence of different types of enhanced system support on user performance during the management of a central heating system. A computer-based simulation of a central heating system, called CHESS V2.0, was used to model different interface options, providing different support facilities to the user (e.g., historical, predictive, and instructional displays). Seventy-five participants took part in the study and completed a series of operational scenarios under different support conditions. The simulation environment allowed the collection of performance measures (e.g., energy consumption), information sampling, and system control behaviour. Subjective user evaluations of various aspects of the system were also measured. The results showed performance gains for predictive displays whereas no such benefits were observed for the other display types. The data also revealed that status and predictive displays were valued most highly by users. The implications of the findings for designers of central heating systems are discussed.

    In this study, we demonstrate how materials science can be combined with the established methods of organic chemistry to find mechanistic bottlenecks and redesign heterogeneous catalysts for improved performance. By using solid-state NMR, infrared spectroscopy, surface and kinetic analysis, we prove the existence of a substrate inhibition in the aldol condensation catalyzed by heterogeneous amines. We show that modifying the structure of the supported amines according to the proposed mechanism dramatically enhances the activity of the heterogeneous catalyst. We also provide evidence that the reaction benefits significantly from the surface chemistry of the silica support, which plays the role of a co-catalyst, giving activities up to two orders of magnitude larger than those of homogeneous amines. This study confirms that the optimization of a heterogeneous catalyst depends as much on obtaining organic mechanistic information as it does on controlling the structure of the support.

    Although several cross-sectional surveys have shown that certain traits such as extraversion and neuroticism are related to emotion regulation, few studies have explored the nature of this relationship. The present study tried to explore the longitudinal relation between traits and emotion regulation strategies. The Interpersonal Self-Support Scale for Middle School Students (ISSS-MSS) and the Emotion Regulation Questionnaire (ERQ) were administrated to 374 middle school students two times across a 6-month interval. A path analysis via structural equation modeling of the five interpersonal self-support traits and the two emotion regulation strategies was tested. The results showed that interpersonal independence predicted expressive suppression and cognitive reappraisal, and that interpersonal initiative also predicted reappraisal, while reappraisal predicted interpersonal flexibility and interpersonal openness 6 month later. These results support the hypotheses that some personality traits influence certain emotion regulation strategies, while other traits may be influenced by specific emotion regulation strategies.

    Pornography consumption may affect judgments on a wide range of sexual and reproductive topics. The present study hypothesized that the consistent images projected in pornography affect sexual scripts related to abortion judgments. National, three-wave longitudinal data gathered from U.S. adults were employed to examine associations between earlier pornography consumption and subsequent support for abortion. The findings suggested that prior pornography consumption may lead to later support for abortion. This study provides additional evidence of pornography's socializing impact, particularly for the older White segment of the population, and adds to knowledge about what environmental factors influence judgments about abortion. Mechanisms that may explain how pornography viewing shapes support for abortion are discussed.

    To explore the resources that patients diagnosed with type 2 diabetes drew upon to manage the disease in their daily lives. Type 2 diabetes is a disease affecting Australian adults at a rate described as an 'epidemic'. Treatment usually focuses on patient self-management, which may require daily blood sugar monitoring, oral medications or injectable therapies, and regulating diet and exercise. Health research studies of patient self-management, including those involving type 2 diabetes, have focused largely on individual-centred definitions, though a number of studies, in particular qualitative studies, have indicated the positive role of social relationships and informal social networks. Exploratory, qualitative. The project focused on 26 patients attending a diabetes centre for clinical consultations with centre staff including doctors, diabetes educators, podiatrists and dietitians. The consultations were observed and audio recorded, followed by semi-structured, audio-recorded interviews with the patients and separate interviews with the consulting professional staff. Overwhelmingly the patients drew on informal social networks of support to manage the disease. Spouses were significant, sometimes presenting with the patient as a 'team' approach to managing the disease. Sons and daughters also played a significant support role, especially interpreting during consultations and explaining health information. In some cases neighbours and also local community organisations provided informal support. Only two patients claimed not to use informal social support. Informal social support in patients' self-management of type 2 diabetes was found to be an important factor to be considered by clinicians. The study suggested the need for a more deliberate or pro-active policy to involve patients' family and other informal social networks in treatment programs. Clinicians may need document and incorporate informal social support in the development and implementation of

    Graphical abstract: - Highlights: • New model catalyst on “AlOx-thin film/FeCrAl” support is presented. • Metal substrate minimizes sample charging, allows fast and uniform heating. • Surface is rough to model the catalyst support's morphology. • Planar alumina is stable in air/gases/solutions and similar to γ-Al{sub 2}O{sub 3}. • New model support is suitable for in situ XPS, STM, TPD, TPR, etc. - Abstract: The preparation of thin continuous alumina film at the surface of metal substrate in UHV (ultra high vacuum) conditions is described. The peculiarities of the obtained films studied by XPS (X-ray photoelectron spectroscopy) and STM (scanning tunneling microscopy) are discussed. The long-term durability of the oxide film was tested and proved both under ambient conditions and in acidic aqueous solutions. The stability of the planar alumina samples toward oxidation by oxygen was checked in the wide ranges of gas pressure and sample temperature. The suggested procedure ensures the controlled and reproducible preparation of thin alumina films – model support appropriate for wet chemistry catalyst preparation, suitable for STM and for other Surface Science techniques studies of alumina supported metal catalysts.

  13. Improving IT Service Management Processes: A Case Study on IT Service Support

    Science.gov (United States)

    Lahtela, Antti; Jäntti, Marko

    IT services and IT service management play a very important role in the today's IT industry. Software as service approach enables IT customers to focus on using the software while IT service providers take care of the installation, configuration, support and maintenance activities. Various process frameworks can be used to improve IT service management processes. The most widely used IT service management framework is the IT Infrastructure Library (ITIL) that provides best practices for IT service providers on how to design, manage and support IT services. Despite the IT service management process frameworks, implementing an effective service support interface between an IT service provider and an IT customer is a big challenge. The research problem in this study is: what types of challenges are related to the service support interface between an IT service provider and IT customers. The main contribution of this paper is present challenges in a service support interface identified during a case study with a large IT service provider company in Finland.

    Quantitative studies have demonstrated that depression and anxiety in the perinatal period are common amongst women in low- and middle-income countries and are associated with a range of psychosocial and health-related stressors. In this exploratory qualitative study conducted in southern Malawi, we investigated the thoughts and emotions experienced by women in pregnancy and the postnatal period, their expectations of support from husband and others, problems and difficulties faced and the impact of these on psychological wellbeing. We conducted 11 focus group discussions with a total of 98 parous women. A thematic analysis approach was used. Three major themes were identified: pregnancy as a time of uncertainty, the husband (and others) as support and stressor, and the impact of stressors on mental health. Pregnancy was seen as bringing uncertainty about the survival and wellbeing of both mother and unborn child. Poverty, lack of support, HIV, witchcraft and child illness were identified as causes of worry in the perinatal period. Husbands were expected to provide emotional, financial and practical support, with wider family and friends having a lesser role. Infidelity, abuse and abandonment were seen as key stressors in the perinatal period. Exposure to stressors was understood to lead to altered mental states, the symptoms of which are consistent with the concept of common perinatal mental disorder. This study confirms and expands on evidence from quantitative studies and provides formative data for the development of a psychosocial intervention for common perinatal mental disorder in Malawi.

    Full Text Available BACKGROUND Organophosphorus compound poisoning is the most common poisonings in India because of easy availability, often requiring ICU care and ventilator support. Clinical research has indicated that respiratory failure is the most important cause of death due to Organophosphorus poisoning. It results in respiratory muscle weakness, pulmonary oedema, respiratory depression, increased secretions and bronchospasm. These complications and death can be prevented with timely Institution of ventilator support. The aim of present study was to identify the factors and predicting the need for ventilator support and outcome. Aim of the Study- To predict the need for ventilator support and outcome in organophosphate poisoning. MATERIALS AND METHODS Seventy consecutive patients admitted with a history of organophosphorus poisoning at KIMS, Hubli were taken for study after considering the inclusion and exclusion criteria. Detailed history, confirmation of poisoning, examination and other than routine investigations serum pseudocholinesterase and arterial blood gas analysis was done. The severity of organophosphorus poisoning was graded as mild, moderate and severe based on the factors which influence the need for ventilator support. RESULTS This study was conducted in 70 patients, out of which 48 (68.6% were male patients and 22 (31.4% were female patients. Among them 37 (53% patients required ventilation and 33 (47% expired. Chlorpyrifos, Dichlorvos and Monocrotophos were most commonly consumed poisons. 74% patients who consumed these compounds required ventilator support and 73% patients expired. 100% of patients presented with pin point pupil, fasciculation score > 4, respiratory rate > 20, GCS score < 7 and severe grade of poisoning required ventilator support and pseudocholinesterase < 900 U/L, 70% of metabolic acidosis and atropine requirement more than 180 mg within 48 hours required ventilator support and associated with high mortality. CONCLUSION

    Dropout from outpatient mental health treatment may contribute to high rates of relapse and rehospitalization among veterans with chronic posttraumatic stress disorder (PTSD). In a quasi-experimental cohort study, 87 male and 17 female veterans discharging from residential PTSD treatment received either standard referral to outpatient care (N = 77) or standard referrals supplemented by biweekly telephone calls (N = 27). Telephone monitoring and support was feasible and acceptable to 85% of clients. Compared to prior patient cohorts, clients receiving telephone support were twice as likely (88% vs. 43%) to complete an outpatient visit within 1 month of discharge and reported higher satisfaction with care.

  5. Maternal obesity support services: a qualitative study of the perspectives of women and midwives

    Science.gov (United States)

    2011-01-01

    Background Twenty percent of pregnant women in the UK are obese (BMI ≥ 30 kg/m2), reflecting the growing public health challenge of obesity in the 21st century. Obesity increases the risk of adverse outcomes during pregnancy and birth and has significant cost implications for maternity services. Gestational weight management strategies are a high priority; however the evidence for effective, feasible and acceptable weight control interventions is limited and inconclusive. This qualitative study explored the experiences and perceptions of pregnant women and midwives regarding existing support for weight management in pregnancy and their ideas for service development. Methods A purposive sample of 6 women and 7 midwives from Doncaster, UK, participated in two separate focus groups. Transcripts were analysed thematically. Results Two overarching themes were identified, 'Explanations for obesity and weight management' and 'Best care for pregnant women'. 'Explanations' included a lack of knowledge about weight, diet and exercise during pregnancy; self-talk messages which excused overeating; difficulties maintaining motivation for a healthy lifestyle; the importance of social support; stigmatisation; and sensitivity surrounding communication about obesity between midwives and their clients. 'Best care' suggested that weight management required care which was consistent and continuous, supportive and non-judgemental, and which created opportunities for interaction and mutual support between obese pregnant women. Conclusions Women need unambiguous advice regarding healthy lifestyles, diet and exercise in pregnancy to address a lack of knowledge and a tendency towards unhelpful self-talk messages. Midwives expressed difficulties in communicating with their clients about their weight, given awareness that obesity is a sensitive and potentially stigmatising issue. This indicates more could be done to educate and support them in their work with obese pregnant women

    Disability support workers (DSWs) are the backbone of contemporary disability support services and the interface through which disability philosophies and policies are translated into practical action. DSWs often experience workplace stress and burnout, resulting in a high turnover rate of employees within the non-professional disability service workforce. The full implementation of the National Disability Insurance Scheme in Australia is set to intensify the current challenges of attracting and retaining DSWs, as the role becomes characterised by greater demands, ambiguity and conflict. The aim of this study was to explore DSWs' perceptions of enjoyable and challenging aspects of disability support work, sources of stress and burnout and the strategies they use to cope when these issues arise. Twelve DSWs workers providing support for adults living with intellectual and physical disabilities were interviewed. Thematic analysis revealed a superordinate theme of 'Balance' comprising three sub-themes: 'Balancing Negatives and Positives', 'Periods of Imbalance', and 'Strategies to Reclaim Balance'. Participants spoke of the rewarding and uplifting times in their job such as watching a client learn new skills and being shown appreciation. These moments were contrasted by emotionally and physically draining aspects of their work, including challenging client behaviour, earning a low income, and having limited power to make decisions. Participants described periods of imbalance, wherein the negatives of their job outweighed the positives, resulting in stress and sometimes burnout. Participants often had to actively seek support and tended to rely on their own strategies to manage stress. Findings suggest that organisational support together with workplace interventions that support DSWs to perceive the positive aspects of their work, such as acceptance and mindfulness-based approaches, may help to limit experiences of stress and burnout. The further development and

    Studies conducted on infertile women in the literature investigated some features such as depression, anxiety, loneliness, and social support. However, there has been no study examining the relationship between levels of perceived social support and depression in infertile women. Considering this deficiency, the study was conducted to determine the relationship between perceived social support and depression in infertile women. The purpose of this study is to determine the relationship between perceived social support and depression in infertile women. This descriptive and sectional study was conducted between 16 April and 31 October 2012 in in vitro fertilisation (IVF) Centre of Fırat University Re- search Hospital. Sampling formula was used in cases when the number of elements in the population was not known to calculate minimum sample size required to be included in the study. A total of 238 women who applied to the relevant centre between the specified dates constituted the sample group of the study. A Questionnaire Form, Beck Depression Inventory (BDI) and the Multidimensional Scale of Perceived Social Support (MSPSS) were used to collect the data. A pilot study was carried out on nine infertile women. As a result of the pilot study, we formed the final version of the Questionnaire Form. The data of these nine women were not involved in the research. The data obtained from the study was assessed using Statistical Package for the Social Sciences (SPSS; SPSS Inc., Chicago, IL, USA) version 15.0. Percentage distribution, mean, t test, one-way analysis of variance (One-Way ANOVA), and Pearson correlation analysis were used to evaluate the data. The women's total mean score on the BDI was 12.55 ± 8.07. Scores obtained by women on the MSPSS was 15.75 ± 8.53 for the subscale of friend, 21.52 ± 8.20 for the subscale of family, and 15.62 ± 8.45 for the subscale of significant others.

    2011-01-01

    Full Text Available Vulcan XC-72R-supported Fe catalysts have been synthesised for the electroreduction of CO2 to high-added value products. Catalysts were obtained by the polyol method, using ethylene glycol as solvent and reducing agent. Prior to the metal deposition, Vulcan was subjected to different oxidation treatments in order to modify its surface chemistry and study its influence on the physicochemical and electrochemical properties of the catalysts, as well as on the product distribution. The oxidation treatments of the supports modify their textural properties, but do not affect significantly the physicochemical properties of catalysts. However, DEMS studies showed that the carbon support degradation, the distribution of products, and the catalytic activity toward the CO2 electroreduction reaction depend significantly on the surface chemistry of the carbon support.

    This is a case study on support for thinking through computer-mediated communication. Two graduate students were supervised in their research using computer-mediated communication, which was asynchronous and written; the supervisor was not present. The students' reports pointed out there was more planning and editing and low interactivity in this approach relative to face-to-face communication. These attributes were confirmed by their supervisor's report. The students also suggested that the latter was effective in support of a production stage of thinking in research, while the former approach was effective in support of examination of thinking. For distance education to be successful, an appropriate combination of communication media must consider students' thinking stages. Finally, transient and permanent effects should be discriminated in computer-mediated communication.

    The present study is focused on the roadway support in high-stress composite soft rock. This paper expounds the two main features of roadway in soft rock, i.e., great deformation of surrounding rock and remarkable rheological deformation. Furthermore, on the basis of analyzing physico-chemical component of surrounding rock and the situation of the damaged roadway, the method of adopting strong bolting and shotcreting mesh for the primary support, bolting and grouting for the secondary support is put forward in light of the on-the-spot investigation of stress tension, mechanical parameter and engineering geology. The application reveals the method facilitates the continuation of west main roadway and the restoration of shaft station and chambers. Consequently, better techno-economic results have been achieved.

  13. Lessons Learnt from the Improvement of Customer Support Processes: A Case Study on Incident Management

    Science.gov (United States)

    Jäntti, Marko

    IT Infrastructure Library (ITIL) is the most widely used IT service management framework that provides guidelines how to create, manage and support IT services. Service support processes, such as incident management and problem management, are among the first ITIL processes that organizations start to implement. However, several challenges may exist in the process implementation. The research question of this study is: which issues are important in establishing an ITIL-based incident management process? The main contribution of this paper is to present lessons learnt from an ITIL-based process improvement project that focused on establishing an incident management process in an IS department of a university hospital. Our results show that key issues in implementing incident management are to 1) define the basic concepts of incident management with concrete examples and 2) define process interfaces between incident management and other support processes.

    Religious congregations may be well equipped to address veterans' reintegration needs, but little is known about the prevalence and nature of such support. We conducted a mixed methods study using nationally representative congregational survey data and in-depth interviews with congregational leaders. Overall, 28% of congregations nationally reported having programming to support veterans and positive, independent predictors included: community context (county veteran presence, high-poverty census tract, rural compared to urban location); congregational resources (more adult attendees, having a paid employee that spent time on service programs); and external engagement (assessing community needs, collaboration, and social service participation). Qualitative interviews revealed a range of activities, including attending to spiritual issues, supporting mental, physical and social well-being, and addressing vocational, legal, financial, and material needs.

IT support responsibilities comprised the entire hospital, of which clinician eHealth security needs were only part. IT staff believed their support tasks were often fragmented while work responsibilities were hampered by resources shortages. They perceived clinicians as an ongoing security risk to private health information. By comparison clinicians believed IT staff would not adequately support the private and secure application of eHealth for patient care. Preliminary data analysis suggests the tension between these cohorts manifests as an eHealth environment where silos of clinical work are disconnected from silos of IT support work. The discipline-based silos hamper health privacy outcomes. Privacy and security policies, especially those influencing the audit process, will benefit by further research of this phenomenon.

    In this qualitative study, we aimed to investigate work demands experienced by health-care workers in an adult eating disorder inpatient service. We also aimed to investigate the use of social support and job satisfaction in this setting. Twelve health-care workers from an eating disorder inpatient ward, including nurses, health-care support workers, and occupational therapists, participated in semistructured interviews. Interviews were transcribed verbatim and analysed using thematic analysis. A number of work demands were discussed relating to therapeutic care, physical care, and organizational demands. Most participants discussed social support at work as being highly valuable, formally and informally, whereas external support was viewed as less important. Despite the challenges of caring for patients with eating disorders, the majority of participants reported good patient-related job satisfaction, but poor job satisfaction in relation to organizational factors. Eating disorder inpatient care is complex and demanding, necessitating effective teamwork, communication, and support systems among health-care workers. Interventions should be developed to target barriers to care, including time constraints, administrative workload, and insufficient allocation of staff.

    Background Second victims are healthcare workers who experience emotional distress following patient adverse events. Studies indicate the need to develop organisational support programmes for these workers. The RISE (Resilience In Stressful Events) programme was developed at the Johns Hopkins Hospital to provide this support. Objective To describe the development of RISE and evaluate its initial feasibility and subsequent implementation. Programme phases included (1) developing the RISE programme, (2) recruiting and training peer responders, (3) pilot launch in the Department of Paediatrics and (4) hospital-wide implementation. Methods Mixed-methods study, including frequency counts of encounters, staff surveys and evaluations by RISE peer responders. Descriptive statistics were used to summarise demographic characteristics and proportions of responses to categorical, Likert and ordinal scales. Qualitative analysis and coding were used to analyse open-ended responses from questionnaires and focus groups. Results A baseline staff survey found that most staff had experienced an unanticipated adverse event, and most would prefer peer support. A total of 119 calls, involving ∼500 individuals, were received in the first 52 months. The majority of calls were from nurses, and very few were related to medical errors (4%). Peer responders reported that the encounters were successful in 88% of cases and 83.3% reported meeting the caller's needs. Low awareness of the programme was a barrier to hospital-wide expansion. However, over the 4 years, the rate of calls increased from ∼1–4 calls per month. The programme evolved to accommodate requests for group support. Conclusions Hospital staff identified the need for a multidisciplinary peer support programme for second victims. Peer responders reported success in responding to calls, the majority of which were for adverse events rather than for medical errors. The low initial volume of calls emphasises the importance of

    Full Text Available Abstract Background Mental health inpatients smoke at higher rates than the general population and are disproportionately affected by tobacco dependence. Despite the advent of smoke free policies within mental health hospitals, limited systems are in place to support a cessation attempt post hospitalisation, and international evidence suggests that most smokers return to pre-admission smoking levels following discharge. This protocol describes a randomised controlled trial that will test the feasibility, acceptability and efficacy of linking inpatient smoking care with ongoing community cessation support for smokers with a mental illness. Methods/Design This study will be conducted as a randomised controlled trial. 200 smokers with an acute mental illness will be recruited from a large inpatient mental health facility. Participants will complete a baseline survey and will be randomised to either a multimodal smoking cessation intervention or provided with hospital smoking care only. Randomisation will be stratified by diagnosis (psychotic, non-psychotic. Intervention participants will be provided with a brief motivational interview in the inpatient setting and options of ongoing smoking cessation support post discharge: nicotine replacement therapy (NRT; referral to Quitline; smoking cessation groups; and fortnightly telephone support. Outcome data, including cigarettes smoked per day, quit attempts, and self-reported 7-day point prevalence abstinence (validated by exhaled carbon monoxide, will be collected via blind interview at one week, two months, four months and six months post discharge. Process information will also be collected, including the use of cessation supports and cost of the intervention. Discussion This study will provide comprehensive data on the potential of an integrated, multimodal smoking cessation intervention for persons with an acute mental illness, linking inpatient with community cessation support.

    The purpose of the controlled longitudinal study was to determine the effect of a tailored early support intervention method on workers' workplace ergonomics. The main areas of the early support intervention were training, guidance and support for supervisors in finding weak signals of impaired ergonomics. Supervisors were also trained to bring up these weak signals in discussion with employees and to make necessary changes at the workplace. The data consisted of 301 intervention subjects and 235 control subjects working in the field of commerce. The questionnaires were carried out in 2008 and in 2010, and the response rates among both groups were 45%. We used multivariate repeated measures analysis of variance (MANOVA) to test the difference in the groups at two points of time. The main result was that in the areas of work environment, the interaction between group and time was statistically significant (p=0.0004). The work environment improved in the intervention group, but deteriorated in the control. Working methods improved due to the interventions, but physical load factors increased over time in both groups. According to the study, tailored early support intervention has a generally beneficial impact on workers' workplace ergonomics in the areas of work methods, work environment and accident factors.

    This study was carried out to determine whether an extracorporeal membrane oxygenation (ECMO support could be sufficiently conducted by the right ventricle alone from the viewpoint of the hemodynamics and blood gas state. Six infant dogs underwent a bypass between the left pulmonary artery and left atrium with an in-line oxygenator after a left pneumonectomy. Partial ECMO support was conducted simply by opening the circuit, and total ECMO support was conducted by ligating the right pulmonary artery. After the establishment of partial ECMO, approximately one-third of the right ventricular output was passively shunted through the bypass circuit, and the cardiac index and central venous pressure did not change. The mean pulmonary arterial pressures increased significantly. After a complete ligation of the right pulmonary artery, all 6 dogs survived for 12 h, but the cardiac output and blood pressure decreased significantly. The blood gas state was sufficiently maintained throughout the experiment. The results suggest the possibility of using the pumpless ECMO support. However, the flow resistance of the membrane oxygenator proved to still be too high for use in a total pumpless ECMO. Further studies on long-term ECMO and the development of a membrane oxygenator with a considerably low flow-resistance are needed.

    2017-01-01

    Background In the United States, over 15 million informal caregivers provide unpaid care to people with Alzheimer disease (AD). Compared with others in their age group, AD caregivers have higher rates of stress, and medical and psychiatric illnesses. Psychosocial interventions improve the health of caregivers. However, constraints of time, distance, and availability inhibit the use of these services. Newer online technologies, such as social media, online groups, friendsourcing, and crowdsourcing, present alternative methods of delivering support. However, limited work has been done in this area with caregivers. Objective The primary aims of this study were to determine (1) the feasibility of innovating peer support group work delivered through social media with friendsourcing, (2) whether the intervention provides an acceptable method for AD caregivers to obtain support, and (3) whether caregiver outcomes were affected by the intervention. A Facebook app provided support to AD caregivers through collecting friendsourced answers to caregiver questions from participants’ social networks. The study’s secondary aim was to descriptively compare friendsourced answers versus crowdsourced answers. Methods We recruited AD caregivers online to participate in a 6-week-long asynchronous, online, closed group on Facebook, where caregivers received support through moderator prompts, group member interactions, and friendsourced answers to caregiver questions. We surveyed and interviewed participants before and after the online group to assess their needs, views on technology, and experience with the intervention. Caregiver questions were pushed automatically to the participants’ Facebook News Feed, allowing participants’ Facebook friends to see and post answers to the caregiver questions (Friendsourced answers). Of these caregiver questions, 2 were pushed to crowdsource workers through the Amazon Mechanical Turk platform. We descriptively compared characteristics of

    The purpose of this study was to examine the experiences on mothers with regard to the breastfeeding support and management provided by healthcare professionals on an acute care postpartum unit in a multiethnic obstetrical referral center in Montreal, Canada. The study survey was largely based on the UNICEF/World Health Organization's (1998) ten steps to successful breastfeeding. The convenience sample included 60 recently-delivered mothers. Findings indicated that primiparous women and women who delivered by caesarean section consistently received more information about breastfeeding management than multiparous women and women who delivered vaginally. However, the study does suggest that all women, regardless of parity or type of delivery, have information and support needs related to breastfeeding. A total of 29 mothers (67%), who intended to breastfeed exclusively, supplemented with artificial baby milk. Of these mothers, 16 (55%) stated 'milk insufficiency' as their primary reasons for supplementing. Overall, respondents perceived healthcare professionals to be encouraging of breastfeeding, and 48 mothers (80%) were 'moderately' to 'very' satisfied with the breastfeeding education and support received. These findings suggest that overall adherence to breastfeeding best practices in the current study hospital are below targets set by the World Health Organization for 'Baby Friendly' status. Results from the study can be used to target areas for improvement.

    Full Text Available Aims: The aim of this study is to assess the patient compliance to supportive and maintenance periodontal therapy and to determine the reason for noncompliance among young adult patients of Namakkal district, India. Materials and Methods: This was a cross-sectional study conducted on 400 patients who underwent periodontal therapy and subsequently recalled for supportive and maintenance periodontal treatment in the Department of Periodontics, Vivekanandha Dental College for Women, Namakkal. Patients age group 25-35 years and of both gender were equally selected and grouped by occupation and socioeconomic status. According to their compliance with appointments, they are categorized as complete compliance, partially compliance and insufficient or noncompliance. Noncompliance and partially compliance patients were contacted and asked to rate their experience and reason for noncompliance. Results: In this study, 80% of patients showed complete compliance and were regular for supportive periodontal therapy appointments. Women were more regular in maintaining recall appointments than men. Salaried employers showed 84.3% complete compliance, while self-employed personals showed 77% complete compliance and 75% of nonworking personals were regular to the appointment schedule. Noncompliance person has quoted lack of time and forgetting the appointment date as a major reason for missed appointments. Conclusions: This study recommends the need for improvement in communication skills of practitioners and weekend appointment for patient undergoing periodontal maintenance therapy.

  10. Effect of medial arch-heel support in inserts on reducing ankle eversion: a biomechanics study

    2008-02-01

    Full Text Available Abstract Background Excessive pronation (or eversion at ankle joint in heel-toe running correlated with lower extremity overuse injuries. Orthotics and inserts are often prescribed to limit the pronation range to tackle the problem. Previous studies revealed that the effect is product-specific. This study investigated the effect of medial arch-heel support in inserts on reducing ankle eversion in standing, walking and running. Methods Thirteen pronators and 13 normal subjects participated in standing, walking and running trials in each of the following conditions: (1 barefoot, and shod condition with insert with (2 no, (3 low, (4 medium, and (5 high medial arch-heel support. Motions were captured and processed by an eight-camera motion capture system. Maximum ankle eversion was calculated by incorporating the raw coordinates of 15 anatomical positions to a self-compiled Matlab program with kinematics equations. Analysis of variance with repeated measures with post-hoc Tukey pairwise comparisons was performed on the data among the five walking conditions and the five running conditions separately. Results Results showed that the inserts with medial arch-heel support were effective in dynamics trials but not static trials. In walking, they successfully reduced the maximum eversion by 2.1 degrees in normal subjects and by 2.5–3.0 degrees in pronators. In running, the insert with low medial arch support significantly reduced maximum eversion angle by 3.6 and 3.1 degrees in normal subjects and pronators respectively. Conclusion Medial arch-heel support in inserts is effective in reducing ankle eversion in walking and running, but not in standing. In walking, there is a trend to bring the over-pronated feet of the pronators back to the normal eversion range. In running, it shows an effect to restore normal eversion range in 84% of the pronators.

    There is increasing evidence that electronic and other aids can support older people's memory. In an effectiveness study, we explored whether assistive technologies could benefit 200 potential beneficiaries in a naturalistic setting. We first interviewed 50 participants to assess needs and preferences for memory aids, then researched, developed and trialled specific aids, and finally administered a follow-up questionnaire assessing future use of aids. Matching aids to needs was not easy. Relatively few people were interested in trailing aids. Simpler aids were most successful. Participants were curious about electronic aids, but found them too complicated and not adapted enough to their needs. Assistance from other people was necessary to prompt use of all types of aids. Future effectiveness studies should focus on longer trials with greater training and support for participants, a wider range of technologies, and more promotion of possible benefits. © The Author(s) 2012.

    This paper reports on tools and methodologies developed to study the impact of adding rooftop photovoltaic (PV) systems, with and without the ability to provide voltage support, on the voltage profile of distribution feeders. Simulation results are provided from a study of a specific utility feeder. The simulation model of the utility distribution feeder was built in OpenDSS and verified by comparing the simulated voltages to field measurements. First, we set all PV systems to operate at unity power factor and analyzed the impact on feeder voltages. Then we conducted multiple simulations with voltage support activated for all the smart PV inverters. These included different constant power factor settings and volt/VAR controls.

    Grounded in stage-environment fit theory, this study adopts a longitudinal design to examine the contribution of autonomy support from teachers to reducing adolescent anxiety and depression. A total of 236 Chinese adolescents (57.38% females, Mage = 14.34) completed questionnaires on teacher autonomy support, basic psychological needs satisfaction, school engagement, anxiety, and depression in the fall and spring semesters of their 7th and 8th grade years. The results showed that teacher autonomy support in the fall of 7th grade boosted basic psychological needs satisfaction in the spring of 7th grade; this, in turn, increased school engagement in the fall of 8th grade, which subsequently decreased anxiety and depression in the spring of 8th grade. These findings demonstrated the significant effect of teacher autonomy support on reducing adolescent anxiety and depression; furthermore, it highlighted the mediating roles of basic psychological needs satisfaction and school engagement in this relationship.

    Locomotion involves complex neural networks responsible for automatic and volitional actions. During locomotion, motor strategies can rapidly compensate for any obstruction or perturbation that could interfere with forward progression. In this pilot study, we examined the contribution of interlimb pathways for evoking muscle activation patterns in the contralateral limb when a unilateral perturbation was applied and in the case where body weight was externally supported. In particular, the latency of neuromuscular responses was measured, while the stimulus to afferent feedback was limited. The pilot experiment was conducted with six healthy young subjects. It employed the MIT-Skywalker (beta-prototype), a novel device intended for gait therapy. Subjects were asked to walk on the split-belt treadmill, while a fast unilateral perturbation was applied mid-stance by unexpectedly lowering one side of the split-treadmill walking surfaces. Subject's weight was externally supported via the body-weight support system consisting of an underneath bicycle seat and the torso was stabilized via a loosely fitted chest harness. Both the weight support and the chest harness limited the afferent feedback. The unilateral perturbations evoked changes in the electromyographic activity of the non-perturbed contralateral leg. The latency of all muscle responses exceeded 100ms, which precludes the conjecture that spinal cord alone is responsible for the perturbation response. It suggests the role of supraspinal or midbrain level pathways at the inter-leg coordination during gait.

  15. A research study of sources of support for bottle feeding in new mothers.

    2007-06-01

    This paper asks if there is a difference in mothers' perceptions of the support they receive about bottle feeding from a range of professional and non-professional sources. The findings are put into the context of associated demographic characteristics. It forms part of a larger study, which was a longitudinal postal survey of 500 childbearing women across two health board regions in Scotland. Women were recruited at 34 weeks gestation by post. The results reported here are from further postal questionnaires at one and three months postnatally. Older women and those with higher education were more likely to initiate and maintain breast feeding, and less likely to introduce solid foods early. Younger women, who were mainly bottle feeding, were more likely to feel they had enough knowledge about feeding their infants than older women and were significantly more likely to feel that relatives were supportive about infant feeding. However, findings suggest that this confidence is largely dependent upon the support provided by relatives. Given the likelihood of misinformation and the potential for passing on inappropriate practices, this issue merits further examination. Health promotion strategies aimed at relatives of new mothers could, therefore, help to redress this and, thereby, promote more health advantages for the infants involved. However, there may be a large number of younger women who do not have knowledgeable support for infant feeding from relatives or friends and for whom access to health professionals for this information is restricted, possibly leading to poor infant-feeding decisions.

    Head injuries are the most common severe injuries sustained by pediatric occupants in road traffic crashes. Preventing children from adopting positions that can result in an increased injury risk due to unfavorable interactions with the restraints is fundamental. The objective of this paper was to assess the effect of a head support system (SS) on the lateral position of the head, the vertical position of the sternum and the shoulder belt fit. Thirty pediatric rear-seat passengers were exposed to two 75-minute trials. Volunteers were restrained by a three-point belt and, if needed, used the appropriate child restraint system for their anthropometry (high-back booster, low-back booster, no booster). A case crossover study was designed in which the volunteers used the head support system (SS) during one of the trials, acting as their own controls (No SS) in the other. Compared to the control group, the head support reduced significantly the 90(th) percentile value of the absolute value of the relative lateral motion of the head, regardless of the restraint used. The system also reduced the maximum downward position of the sternal notch within the low-back booster group. As for the belt fit, the use of the head support improved significantly the position of the shoulder belt on the occupant in the low-back booster and in the no booster groups.

    Full Text Available As the second largest producer of cement after Egypt in the Middle East, Iran planned to increase production from 33 million ton/yr (Mt/yr currently to 70 Mt/yr by 2021 due to increase in local demand and also to compete in export markets (Dehqan, 2002. Thus, Iran is experiencing some changes in workforce participation in order to achieve high level of organisational performance and effectiveness. The objective of this study is to determine the impact of leadership behavior and perceived organisational support on the job satisfaction of Iranian employees. Data were collected through questionnaire from 136 employees working in Tehran Cement Company. Consideration leadership behavior was found to have significant impact on both intrinsic and extrinsic job satisfaction whereas perceived organisational support was significantly related to extrinsic job satisfaction. Interestingly, the interaction of leadership behavior and perceived organisational support were not significantly related to job satisfaction. The implications to human resource development for organizations that want to increase employee commitment is to focus on improving the quality of the supportive relationships between the employees and both the leader and the organisation.

    Psychosocial Clubhouses provide recovery-focused psychosocial rehabilitation to people with serious mental illness at over 300 sites in more than 30 countries worldwide. To deliver the services involved, Clubhouses employ a complex mix of theory, programs and relationships, with this complexity presenting a number of challenges to those undertaking Clubhouse research. This paper provides an overview of the usefulness of case study designs for Clubhouse researchers; and suggests ways in which the evaluation of Clubhouse models can be facilitated. The paper begins by providing a brief explanation of the Clubhouse model of psychosocial rehabilitation, and the need for ongoing evaluation of the services delivered. This explanation is followed by an introduction to case study design, with consideration given to the way in which case studies have been used in past Clubhouse research. It is posited that case study design provides a methodological framework that supports the analysis of either quantitative, qualitative or a mixture of both types of data to investigate complex phenomena in their everyday contexts, and thereby support the development of theory. As such, case study approaches to research are well suited to the Clubhouse environment. The paper concludes with recommendations for future Clubhouse researchers who choose to employ a case study design. While the quality of case study research that explores Clubhouses has been variable in the past, if applied in a diligent manner, case study design has a valuable contribution to make in future Clubhouse research.

  20. Male students give voice to supportive campus environments: A qualitative case study of undergraduate STEM majors

    Amon, Julie L.

    Research supports the importance of student engagement in enhancing student learning, success, and various desirable educational outcomes. In the last decade, the National Survey of Student Engagement (NSSE) has been the primary instrument through which student engagement has been explored. Supportive Campus Environment, one of the five benchmarks of effective educational practice measured by NSSE, served as the foundation for this study. The challenge of successfully educating students in science, technology, engineering, and mathematics (STEM) disciplines has been clearly documented. Recently, urgent calls have been issued to confront the shortage of students in the STEM pipeline, to minimize barriers to the achievement in STEM disciplines, and to increase the representation of racial minorities and women in STEM careers. This study employed a holistic collective case study design to examine how undergraduate men in STEM majors at a private, selective, research institution perceived the supportiveness of their campus environments. Differential perceptions of the campus environment on the basis of race (Black, Indian1, Latino, and White) and academic success were explored. Cross-case analysis revealed several common themes across all cases. Peer relationships, followed by faculty relationships, were most influential in shaping perceptions of campus environment. Race, academic success, and characteristics unique to STEM were less influential to perceptions of the campus environment. Participants distinguished feelings of a supportive campus environment from their overall perceptions of their campus environment. Further, participants routinely isolated some of their identities, experiences, and perceptions from influencing their overall perception of the campus environment. A connection between the concept of supportive campus environment and sense of belonging emerged. Participants' discussion of the NSSE Supportive Campus Environment questions provided valuable

    The dynamics of water condensation on self-supported thin films was studied at the nanoscale using transmitted electrons in an environmental scanning electron microscope. The initial stages of nucleation and growth over nanothick water films have been investigated. Irregularities at the water-film boundaries constituted nucleation sites for asymmetric dropwise and filmwise condensation. Nanodroplet growth was associated with center of mass movement, and the dynamic growth power law dependence was explored for the nanoscale.

    Numerous studies have shown that the quality of health care is inadequate, and healthcare organizations are increasingly turning to clinical decision support systems (CDSS) to address this problem. In implementing CDSS, a highly promising architectural approach is the use of decision support services. However, there are few reported examples of successful implementations of operational CDSS using this approach. Here, we describe how Hospital Italiano de Buenos Aires evaluated the feasibility of using the SEBASTIAN clinical decision support Web service to implement a CDSS integrated with its electronic medical record system. The feasibility study consisted of three stages: first, end-user acceptability testing of the proposed CDSS through focus groups; second, the design and implementation of the system through integration of SEBASTIAN and the authoring of new rules; and finally, validation of system performance and accuracy. Through this study, we found that it is feasible to implement CDSS using a service-based approach. The CDSS is now under evaluation in a randomized controlled trial. The processes and lessons learned from this initiative are discussed.

    Full Text Available Postgraduate studies in business faculties pose particular challenges to candidates who have come from practically-oriented undergraduate programmes, particularly those that adopt a ‘technical-rational’ approach towards the improvement of business practices or organisational efficiency. Research studies in the applied business fields usually expect that the candidate will take a more sociological approach, or be able to work within socio-historical or political frameworks (Hordern, 2014. Candidates who are enrolled for postgraduate business studies have to negotiate this complex transition. The focus of this paper is how candidates acquire the necessary academic and social practices for theorising their research, for conducting research activities and writing up their research findings in Masters level applied business studies. We selected candidates who had experienced difficulties throughout their Masters studies and who had successfully completed, or who were close to completion, despite initial difficulty for narrative interviews. The interview data were analysed with a view to establishing the practices that supported successful transition from practice-based undergraduate business degrees to postgraduate studies in the field. This paper concludes with suggestions for supervisory practices that have the potential to support successful postgraduate research in applied business studies

    Highlights: • A use case example of RIO/FlexRIO design methodology is described. • Ion source device is controlled and monitored by means EPICS IOCs. • NIRIO EPICS device support demonstrates that is able to manage RIO devices. • Easy and fast deployment is possible using RIO/FlexRIO design methodology using NIRIO-EDS. • RIO/FlexRIO technology and EPICS are a good combination for support large scale experiments in fusion environments. - Abstract: Experimental Physics and Industrial Control System (EPICS) is a software tool that during last years has become relevant as a main framework to deploy distributed control systems in large scientific environments. At the moment, ESS Bilbao uses this middleware to perform the control of their Ion Source Hydrogen Positive (ISHP) project. The implementation of the control system was based on: PXI Real Time controllers using the LabVIEW-RT and LabVIEW-EPICS tools; and RIO devices based on Field-Programmable Gate Array (FPGA) technology. Intended to provide a full compliant EPICS IOCs for RIO devices and to avoid additional efforts on the system maintainability, a migration of the current system to a derivative Red Hat Linux (CentOS) environment has been conducted. This paper presents a real application case study for using the NIRIO EPICS device support (NIRIO-EDS) to give support to the ISHP. Although RIO FPGA configurations are particular solutions for ISHP performance, the NIRIO-EDS has permitted the control and monitoring of devices by applying a well-defined design methodology into the previous FPGA configuration for RIO/FlexRIO devices. This methodology has permitted a fast and easy deployment for the new robust, scalable and maintainable software to support RIO devices into the ISHP control architecture.

    The aim of the study was to examine associations of social support with early retirement and reported retirement preference. Logistic regression analyses of early retirement (retired before the age of 55) were based on a cohort of 10,489 respondents (5960 female, 4529 male) aged 40-55 years. Analyses of retirement preference (planning of early retirement) were based on a sub-cohort of 7759 full-time employees (4233 female, 3526 male). The measures for social support were the social network size (number of close personal relationships) and social network heterogeneity (number of different roles as sources of social support). Among women, early retirement was associated with small social networks (OR 5.1, 95% CI = 2.8-9.2) and low social network heterogeneity (OR 9.1, 95% CI = 3.2-25.9). Among men, the corresponding associations were somewhat smaller (1.5; 0.9-2.6 and 8.0; 1.8-35.7, respectively). Adjustments for age, occupational training, and spouse at home did not considerably affect these associations. Among men, the association between social network heterogeneity and early retirement was not statistically significant after additional adjustments had been made for marital status and perceived health status. The characteristics of the social network were not associated with a retirement preference among employed men. Among women, the lack of social relations was associated with low retirement preference. Our findings suggested that social support is not independently associated with a retirement preference among men. Socially isolated women prefer retirement less often than other women do. Being retired before the age of 55 years may be predicted by limited social support or it may restrain one's possibilities to establish and maintain social relationships.

    There are many soft-rock roadway coal mines in China. The surrounding rocks of the high-stress soft-rock roadways in deep mine are especially difficult to be supported using the traditional supporting way. In this study, the south wing rail roadway on the second level of Yunjialing coal mine in China was used as an example to analyze the deformation and failure characteristics and influencing factors of roadway. On this basis, this study proposed the equalized yielding support idea which employs the yielding rings to realize the pressure equalization on the bolts and cables in the section. To achieve this purpose, the first bolt-mesh-cable equalizing pressure yielding support was integrated with the second grouting reinforcement. The results proved that the yield rings of the bolts and cables on the spandrel of the arched roadway firstly developed yielding deformation;then the deformation extended to the vault of the roadway;the bolts and cables achieved a yielding extreme value of 15 and 18 tonnes, respectively. The roadway surrounding rock tended to be stable at the 26th day after the maintenance. The equalizing pressure yielding supporting technology plays a moderate pressure-releasing and actively controlling role on the surrounding rocks in the soft-rock roadway with large deformation.

    We study PdPt bimetallic clusters in both free and supported phases. These clusters have been produced with a laser vaporization source. Free clusters directly produced by the source are studied by time of flight mass spectrometry and photofragmentation technique. We observed a sequential evaporation of Pd atoms in the mixed clusters consistent with a palladium segregation process. This tendency has been also observed on supported particles from which the structure and the composition are determined by high resolution transmission electron microscopy and energy dispersive x-ray analysis. A main result is that each particle has the composition of the massic rod vaporized in the source. The supported particles are well crystallized and exhibit truncated octahedron shapes. Experimental observations are well explained using a modified tight binding model. Indeed, within this model, we found that the equilibrium shape is strongly related to the variation of the cohesive energy with atomic coordination number. Also, some preliminary results on the specific reactivity of these bimetallic clusters are presented.

  15. Hypothesis support measured by likelihood in the presence of nuisance parameters, multiple studies, and multiple comparisons

    2011-01-01

    By leveraging recent advances in J. Rissanen's information-theoretic approach to model selection that has historical roots in the minimum description length (MDL) of a message, the Bayes-compatibility criterion of A. W. F. Edwards is recast in terms of predictive distributions to make the measure of support robust not only in the presence of nuisance parameters but also in the presence of multiple studies and multiple comparisons within each study. To qualify as a measure of support, a statistic must asymptotically approach the difference between the posterior and prior log-odds, where the parameter distributions considered are physical in the empirical Bayes or random effects sense that they correspond to real frequencies or proportions, e.g., of hypotheses, whether or not the distributions can be estimated and even whether or not data pertaining to the hypotheses are available. Because that Bayes-compatibility condition is weak, an optimality criterion is needed to uniquely specify a measure of support. Two...

    Automatic identification of flaws is very important for ultrasonic nondestructive testing and evaluation of large shaft. A novel automatic defect identification system is presented. Wavelet packet analysis (WPA) was applied to feature extraction of ultrasonic signal, and optimal Support vector machine (SVM) was used to perform the identification task. Meanwhile, comparative study on convergent velocity and classified effect was done among SVM and several improved BP network models. To validate the method, some experiments were performed and the results show that the proposed system has very high identification performance for large shafts and the optimal SVM processes better classification performance and spreading potential than BP manual neural network under small study sample condition.

  19. The Dilemma of Supporting Electrolytes for Electroorganic Synthesis: A Case Study on Kolbe Electrolysis.

    2016-01-08

    Remarkably, coulombic efficiency (CE, about 50 % at 1 Farad equivalent), and product composition resulting from aqueous Kolbe electrolysis are independent of reactor temperature and initial pH value. Although numerous studies on Kolbe electrolysis are available, the interrelations of different reaction parameters (e.g., acid concentration, pH, and especially electrolytic conductivity) are not addressed. A systematic analysis based on cyclic voltammetry reveals that solely the electrolytic conductivity impacts the current-voltage behavior. When using supporting electrolytes, not only their concentration, but also the type is decisive. We show that higher concentrations of KNO3 result in reduced CE and thus in significant increase in electric energy demand per converted molecule, whereas Na2 SO4 allows improved space-time yields. Pros and cons of adding supporting electrolytes are discussed in a final cost assessment.

    Recovery can be understood as a subjective process guided by personal expectations, goals and hopes. The aim of the study was to explore how persons using a Community Mental Health Centre (CMHC) experienced that their expectations for treatment, and goals and hopes for recovery were supported by the health professionals during treatment. Employing a hermeneutic-phenomenological approach, eight service users were interviewed about their expectations for treatment and their goals and hopes for recovery at the start of their contact with health professionals at a CMHC. Two years later, they were re-interviewed about their experiences of treatment and support from the health professionals in their work towards these goals and hopes. A collaborative approach was adopted. A co-researcher with lived experience took part in all stages of the study. Data were analysed by means of a data-driven stepwise approach in line with thematic analysis. Five themes reflecting how participants experienced support from health professionals at the CMHC in their work towards their recovery goals were elicited, as follows: developing an understanding of oneself and one's mental health problems; learning how to change feelings and behaviours; being 'pushed' into social arenas; finding helpful medication; and counselling in family, practical and financial issues. The participants' expectations about counselling with regard to longer-term family, practical, and financial challenges were insufficiently met by the CMHC. In the experience of the service users, recovery occurred within the context of their everyday life with or without the support of their professional helpers. To facilitate recovery, health professionals should acknowledge the service user's personal goals and hopes and take a more comprehensive and longer-term approach to his or her needs and desires.

    The present study, taking a resource-oriented approach to mental health, aimed at investigating mental resilience and its determinants among undergraduate physiotherapy students using quantitative and qualitative tools. A questionnaire-based cross-sectional survey supplemented by 2 focus groups. One university in Hungary. 130 physiotherapy students at years 1, 2, and 3. Sense of coherence, a measure of dynamic self-esteem, as well as social support from family and peers were used to assess mental well-being. A screening instrument for psychological morbidity and perceived stress were used as deficiency-oriented approaches. Student opinions were gathered on positive and negative determinants of mental health. Resilience was lower [mean difference 4.8 (95% CI -3.4; 13.1)], and the occurrence of psychological morbidity (32.5% vs. 0%) was higher among female compared to male students. However, the proportion of students fully supported by their peers was higher among females (63% vs. 37.5%). Female students, unlike their male counterparts, experienced higher stress compared to their peers in the general population. Social support declined as students progressed in their studies though this proved to be the most important protective factor for their mental well-being. Results were fed back to the course organizers recommending the implementation of an evidence-based method to improve social support as delineated by the Guide to Community Preventive Services of the US the outcomes of which are to be seen in the future.

    This study aimed to clarify why and how clinical nurses facilitate sitting without trunk support among patients with disorders of consciousness. Recent attention has focused on encouraging patients with disorders of consciousness to sit without trunk support, but no reports describe this intervention among patients with poor awareness and physical disuse. Qualitative research design. We enrolled five clinical nurses with interventional experience in rehabilitating patients with disorders of consciousness to sit without trunk support. Participant observation and semi-structured interviews were used to collect data. The data were analysed by text-mining method. Three reasons for nursing in the sitting position were identified: to raise the patient's body to assess the recovery of activities of daily living, to adjust their circadian rhythm and encourage the will to sit, and to make it easier to breathe. Five practices were identified: moving the patient to the prone position to sit in safety and comfort, developing postural stability by improving the flexibility of the lower limbs, improving the flexibility of the hip joints, developing trunk balance and encouraging hand use for stability, and ensuring safety by terminating the sitting practice when symptoms of respiratory failure, heart failure, or excessive tiredness developed. The rationale for nursing patients with disorders of consciousness to sit without trunk support was to establish a foundation for independent living. This was achieved by preparing patient's disused body for activity by improving the flexibility of hip joint in the prone position. This represents a new intervention for patients with disorders of consciousness that could facilitate independent living. This study provides empirical and practical evidence from nurses who perform novel clinical interventions that specifically promote independent living. Further accumulation of quantitative clinical results and physiological verification are

    2012-04-01

    Full Text Available Understanding knowledge work and supporting it with information systems (ISs are challenging tasks. Knowledge work has changed substantially recently and studies on how knowledge work is currently performed are scarce. Ethnography is the most suitable qualitative research method for studying knowledge work, yet too time-consuming, costly and unfocused for the fast changing IS domain. Moreover, results from qualitative studies need to be transformed into artefacts useful for IS requirements engineering and design. This paper proposes a procedure for collaborative ethnography to study knowledge work practices and inform IS requirements gathering and design illustrated with the case of a collaborative ethnographic study of seven organisations in four European countries performed in a large-scale international IS research and development project. The paper also critically discusses the procedure’s applicability and limitations.

    2014-01-24

    Support groups for children in troubled families are available in a majority of Swedish municipalities. They are used as a preventive effort for children in families with different parental problems such as addiction to alcohol/other drugs, mental illness, domestic violence, divorce situations, or even imprisonment. Children from families with these problems are a well-known at-risk group for various mental health and social problems. Support groups aim at strengthening children's coping behaviour, to improve their mental health and to prevent a negative psycho-social development. To date, evaluations using a control-group study design are scarce. The aim of the current study is to evaluate the effects of support groups. This paper describes the design of an effectiveness study, initially intended as a randomized controlled trial, but instead is pursued as a quasi-experimental study using a non-randomized control group. The aim is to include 116 children, aged 7-13 years and one parent/another closely related adult, in the study. Participants are recruited via existing support groups in the Stockholm county district and are allocated either into an intervention group or a waiting list control group, representing care as usual. The assessment consists of questionnaires that are to be filled in at baseline and at four months following the baseline. Additionally, the intervention group completes a 12-month follow-up. The outcomes include the Strength and Difficulties Questionnaire (SDQ S11-16), the Kids Coping Scale, the "Ladder of life" which measures overall life satisfaction, and "Jag tycker jag är" (I think I am) which measures self-perception and self-esteem. The parents complete the SDQ P4-16 (parent-report version) and the Swedish scale "Familjeklimat" (Family Climate), which measures the emotional climate in the family. There is a need for evaluating the effects of support groups targeted to children from troubled families. This quasi-experimental study

    Planar supported lipid bilayers that are stable under ambient atmospheric and ultra-high-vacuum conditions were prepared by cross-linking polymerization of bis-sorbylphosphatidylcholine (bis-SorbPC). X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were employed to investigate bilayers that were cross-linked using either redox-initiated radical polymerization or ultraviolet photopolymerization. The redox method yields a more structurally intact bilayer; however, the UV method is more compatible with incorporation of transmembrane proteins. UV polymerization was therefore used to prepare cross-linked bilayers with incorporated bovine rhodopsin, a light-activated, G-protein-coupled receptor (GPCR). A previous study (Subramaniam, V.; Alves, I. D.; Salgado, G. F. J.; Lau, P. W.; Wysocki, R. J.; Salamon, Z.; Tollin, G.; Hruby, V. J.; Brown, M. F.; Saavedra, S. S. J. Am. Chem. Soc. 2005, 127, 5320-5321) showed that rhodopsin retains photoactivity after incorporation into UV-polymerized bis-SorbPC, but did not address how the protein is associated with the bilayer. In this study, we show that rhodopsin is retained in supported bilayers of poly(bis-SorbPC) under ultra-high-vacuum conditions, on the basis of the increase in the XPS nitrogen concentration and the presence of characteristic amino acid peaks in the ToF-SIMS data. Angle-resolved XPS data show that the protein is inserted into the bilayer, rather than adsorbed on the bilayer surface. This is the first study to demonstrate the use of ultra-high-vacuum techniques for structural studies of supported proteolipid bilayers.

  6. Providing supportive care to cancer patients: a study on inter-organizational relationships

    2008-02-01

    Full Text Available Background: Supportive cancer care (SCC has historically been provided by organizations that work independently and possess limited inter-organizational coordination. Despite the recognition that SCC services must be better coordinated, little research has been done to examine inter-organizational relationships that would enable this goal. Objective: The purpose of this study was to describe relationships among programs that support those affected by cancer. Through this description the study objective was to identify the optimal approach to coordinating SCC in the community. Methods: Senior administrators in programs that provided care to persons and their families living with or affected by cancer participated in a personal interview. Setting: South-central Ontario, Canada. Study population: administrators from 43 (97% eligible programs consented to participate in the study. Results: Network analysis revealed a diffuse system where centralization was greater in operational than administrative activities. A greater number of provider cliques were present at the operational level than the administrative level. Respondents identified several priorities to improve the coordination of cancer care in the community including: improving standards of care; establishing a regional coordinating body; increasing resources; and improving communication between programs. Conclusion: Our results point to the importance of developing a better understanding on the types of relationships that exist among service programs if effective integrated models of care are to be developed.

    It is frequently argued that, at the parcel level, stakeholders are capable of and well supported in managing their land-related risks. Yet, evidence from the contemporary Australian context suggests otherwise: numerous large-scale disaster events have revealed that citizens are ill-prepared to respond and recover adequately. This paper begins with the premise that information, specifically land information, could better support parcel-level risk preparation, mitigation, response, and recovery. State land administration organisations in Australia primarily maintain this information and make it accessible. Land information is used regularly across all levels of government to support risk management activities; however, such application has not always occurred at the parcel and citizen level. Via a case study approach, this paper initially explores the land information available in Australia to stakeholders interested in parcel-level detail, and then goes on to propose how the utilisation of parcel-level land information could serve to enhance risk management practices. © 2017 The Author(s).

    Full Text Available Nowadays, terrestrial laser scanning shows the potential to improve construction productivity by measuring the objects changes using real-time applications. This paper presents the process of implementation of an efficient framework for precast concrete using terrestrial laser scanning that enables contractors to acquire accurate data and support Quality Assessment System in Construction (QLASSIC. Leica Scanstation C10, black/white target, Autodesk Revit and Cyclone software were used in this study. The results were compared with the dimensional of based model precast concrete given by the company as a reference with the AutoDesk Revit model from the terrestrial laser scanning data and conventional method (measuring tape. To support QLASSIC, the tolerance dimensions of cast in-situ & precast elements is +10mm / -5mm. The results showed that the root mean square error for a Revit model is 2.972mm while using measuring tape is 13.687mm. The accuracy showed that terrestrial laser scanning has an advantage in construction jobs to support QLASSIC.

    A comparison study has been conducted on the formation of catalyst nanoparticles on a high surface tension metal and low surface tension oxide for carbon nanotube (CNT) growth via catalytic chemical vapor deposition (CCVD). Silicon dioxide (SiO2) and tantalum have been deposited as supporting layers before deposition of a thin layer of iron catalyst. Iron nanoparticles were formed after thermal annealing. It was found that densities, size distributions, and morphologies of iron nanoparticles were distinctly different on the two supporting layers. In particular, iron nanoparticles revealed a Volmer-Weber growth mode on SiO2 and a Stranski-Krastanov mode on tantalum. CCVD growth of CNTs was conducted on iron/tantalum and iron/SiO2. CNT growth on SiO2 exhibited a tip growth mode with a slow growth rate of less than 100nm /min. In contrast, the growth on tantalum followed a base growth mode with a fast growth rate exceeding 1μm/min. For comparison, plasma enhanced CVD was also employed for CNT growth on SiO2 and showed a base growth mode with a growth rate greater than 2μm /min. The enhanced CNT growth rate on tantalum was attributed to the morphologies of iron nanoparticles in combination with the presence of an iron wetting layer. The CNT growth mode was affected by the adhesion between the catalyst and support as well as CVD process.

    To examine the correlation between maternal parental self-efficacy and social support as well as predictors of self-efficacy in the early postpartum period. Maternal parental self-efficacy is important for mothers' adaptation to motherhood. Lack of support could result in decreased maternal parental self-efficacy in newborn care. Limited studies have focused on maternal parental self-efficacy in the postpartum period in Asia and none in Singapore. A correlational study design was adopted. Data were collected from both primiparas and multiparas during the first to third days postpartum in a public hospital, using the Perceived Maternal Parental Self-efficacy and Perinatal Infant Care Social Support Scales. The data were analysed using descriptive and inferential statistics. Maternal parental self-efficacy in newborn care and the level of social support that mothers received were moderate. In terms of the social support subscales, informational and instrumental support was lower than emotional and appraisal support. Informal support from husbands, parents and parents-in-law was the main source of support. A significant correlation was found between maternal parental self-efficacy and total social support in addition to the informational, instrumental and appraisal subscales of functional support. The predictors of maternal parental self-efficacy were parity, social support and maternal age. The findings highlight the predictors and correlates of maternal parental self-efficacy in newborn care and the social support needs of mothers in the early postpartum period. Healthcare professionals could provide more information and instrumental support and involve family members to enhance maternal parental self-efficacy. Because maternal parental self-efficacy and social support in the early postpartum period are interrelated components, they could be assessed to identify at-risk mothers. There is a need to develop perinatal educational programmes to provide culturally

    Poor interprofessional communication poses a risk to patient safety at change-of-shift in emergency departments (EDs). The purpose of this study was to identify and describe patterns and processes of interprofessional communication impacting quality of ED change-of-shift handovers. Observation of 66 change-of-shift handovers at two acute hospital EDs in Victoria, Australia. Focus groups with 34 nurse participants complemented the observations. Qualitative data analysis involved content and thematic methods. Four structural components of ED handover processes emerged represented by (ABCD): (1) Antecedents; (2) Behaviours and interactions; (3) Content; and (4) Delegation of ongoing care. Infrequent and ad hoc interprofessional communication and discipline-specific handover content and processes emerged as specific risks to patient safety at change-of-shift handovers. Three themes related to risky and effective practices to support interprofessional communications across the four stages of ED handovers emerged: 1) standard processes and practices, 2) teamwork and interactions and 3) communication activities and practices. Unreliable interprofessional communication can impact the quality of change-of-shift handovers in EDs and poses risk to patient safety. Structured reflective analysis of existing practices can identify opportunities for standardisation, enhanced team practices and effective communication across four stages of the handover process to support clinicians to enhance local handover practices. Future research should test and refine models to support analysis of practice, and identify and test strategies to enhance ED interprofessional communication to support clinical handovers.

    2010-06-01

    Full Text Available Abstract Background The continuing gap between the number of people requiring treatment for substance use disorders and those receiving treatment suggests the need to develop new approaches to service delivery. Meanwhile, the use of technology to provide counseling and support in the substance abuse field is exploding. Despite the increase in the use of technology in treatment, little is known about the impact of technology-supported interventions on access to services for substance use disorders. The E-TREAT intervention brings together the evidence-based practice of Motivational Interviewing and theories of Persuasive Technology to sustain clients' motivation to change substance use behaviors, provide support for change, and facilitate continuity across treatment settings. Methods This study used descriptive statistics, tests of statistical significance, and logistic regression to explore the characteristics and perceptions of the first 157 people who agreed to participate in E-TREAT and the predictors of their active engagement in E-TREAT services. In addition, responses to open-ended questions about the participants' experiences with the intervention were analyzed. Results The data reveal that clients who engaged in E-TREAT were more likely than those who did not engage to be female, have children and report a positive relationship with their recovery coach, and were less likely to have completed treatment for a substance use disorder in the past. A majority of people engaging in E-TREAT reported that it was helpful to talk with others with similar problems and that the program assisted them in developing a sense of community. Conclusions The authors conclude that technology-assisted interventions hold promise in expanding access to treatment for substance use disorders especially for women and parents. Further, the characteristics of the relationship with a coach or helper may be critical to engagement in technology-supported interventions

    The instrumentation requirements for a regenerative life support systems were studied to provide the earliest possible indication of a malfunction that will permit degradation of the environment. Four categories of parameters were investigated: environmental parameters that directly and immediately influence the health and safety of the cabin crew; subsystems' inputs to the cabin that directly maintain the cabin environmental parameters; indications for maintenance or repair; and parameters useful as diagnostic indicators. A data averager concept is introduced which provides a moving average of parameter values that is not influenced by spurious changes, and is convenient for detecting parameter rates of change. A system is included to provide alarms at preselected parameter levels.

    Although the roles of the intrapartum nurse and professional doula differ markedly, they serve women best if their roles complement each other. For doulas and nurses to work well together in order to facilitate a positive birth experience for the patient, they would logically need to develop a relationship based on mutual respect. The purpose of this pilot qualitative study was to examine the level of acceptance shown by intrapartum nurses for doula support, as perceived by the parturient woman. Implications for further research are addressed.

    To understand how family physicians facilitate older patients' access to community support services (CSSs) and to identify similarities and differences across primary health care (PHC) models. Qualitative, multiple-case study design using semistructured interviews. Four models of PHC delivery, specifically 2 family health teams (FHTs), 4 non-FHTs family health organizations, 4 fee-for-service practices, and 2 community health centres in urban Ontario. Purposeful sampling of 23 family physicians in solo and small and large group practices within the 4 models of PHC. A multiple-case study approach was used. Semistructured interviews were conducted and data were analyzed using within- and cross-case analysis. Case study tactics to ensure study rigour included memos and an audit trail, investigator triangulation, and the use of multiple, rather than single, case studies. Three main themes were identified: consulting and communicating with the health care team to create linkages; linking patients and families to CSSs; and relying on out-of-date resources and ineffective search strategies for information on CSSs. All participants worked with their team members; however, those in FHTs and community health centres generally had a broader range of health care providers available to assist them. Physicians relied on home-care case managers to help make linkages to CSSs. Physicians recommended the development of an easily searchable, online database containing available CSSs. This study shows the importance of interprofessional teamwork in primary care settings to facilitate linkages of older patients to CSSs. The study also provides insight into the strategies physicians use to link older persons to CSSs and their recommendations for change. This understanding can be used to develop resources and approaches to better support physicians in making appropriate linkages to CSSs. Copyright© the College of Family Physicians of Canada.

    Poor medication adherence in adolescents with asthma results in poorly controlled disease and increased morbidity. The aim of the ADolescent Adherence Patient Tool (ADAPT) study is to develop an mHealth intervention to support self-management and to evaluate the effectiveness in improving medication adherence and asthma control. The ADAPT intervention consists of an interactive smartphone application (app) connected to a desktop application for health care providers, in this study, the community pharmacist. The app contains several functions to improve adherence as follows: 1) a questionnaire function to rate asthma symptoms and monitor these over time; 2) short movie clips with medication and disease information; 3) a medication reminder; 4) a chat function with peers; and 5) a chat function with the pharmacist. The pharmacist receives data from the patient's app through the desktop application, which enables the pharmacist to send information and feedback to the patient. The ADAPT intervention is tested in a community pharmacy-based cluster randomized controlled trial in the Netherlands, aiming to include 352 adolescents with asthma. The main outcome is adherence, measured by patient's self-report and refill adherence calculated from pharmacy dispensing records. In addition, asthma control, illness perceptions, medication beliefs, and asthma-related quality of life are measured. This study will provide in-depth knowledge on the effectiveness of an mHealth intervention to support asthma self-management in adolescents. These insights will also be useful for adolescents with other chronic diseases.

    Considering the demand of urban and rural planning and the characteristics of spatial information technology (SIT), the study focuses on the application of SIT to support multi-scale urban planning. Three scales of urban and rural planning, such as city and town system planning, urban master planning, and detailed urban planning, were studied based on SIT. Firstly, tacking Great Beijing Region as an example, which includes Beijing, Tianjin, and northern of Hebei province, the city and town system planning was studied, supported by the theory of spatial interaction between cities and towns, and GIS spatial analysis. Then, for the urban master planning of Beijing, the RS and GIS were applied to do the spatial development analysis based on RS image data and GIS spatial analysis. Regarding to the conservation planning of Beijing's Inner city, the third scale is detailed urban planning. RS, GIS, and VR were integrated to determine the conservation region and digital conservation way as well. Finally, three conclusions were worked out.

    Jichi Medical University (JMU) is the only medical school in Japan that is devoted solely to producing rural and remote doctors. To support research activities of its graduates, mainly young graduates under obligatory rural service, JMU established a voluntary team, Clinical Research Support Team (CRST)-Jichi. CRST-Jichi consists of current and past JMU faculty members; all of them are specialists of certain medical fields and many are also graduates of JMU who have completed rural service. A client who asks the CRST for advice on study design or editing a paper emails the CRST to ask for support in conducting a study. Then, core members of the CRST assign the job to a registered specialist of the corresponding topic, who becomes a 'responsible supporter' and continues to support the client until a paper has been published. During the 3 years from July 2010, 12 English papers have been published in international peer-review journals, two Japanese papers in domestic journals, and 13 studies are in progress. Ninety-one percent of clients were satisfied with the service, and eighty-two percent considered their papers would not have been published if they had not used the service. Sense of commitment, existence of JMU-graduated specialists, and quick response were reported by clients as major strengths of CRST-Jichi. The experience of CRST-Jichi can potentially be transferred to not only other Japanese medical schools with rural doctor production programs, which are now rapidly increasing as part of a national policy, but also rural medical education systems in other countries.

    Full Text Available This study explored the capacity of Web-based, group communication systems to support case-based teaching and learning. Eleven graduate students studying at a distance were divided into three groups to collaborate on a case study using either a synchronous voice, an asynchronous voice, or a synchronous text communication system. Participants kept a detailed log of the time they spent on various activities, wrote a 1,500-word reflection on their experience, and participated in a group interview. Analysis of these data reveals that each group supplemented the system that had been assigned to them with additional communication systems in order to complete the project. Each of these systems were used strategically: email was used to share files and arrange meetings, and synchronous voice systems were used to brainstorm and make decisions. Learning achievement was high across groups and students enjoyed collaborating with others on a concrete task.

    Though functional social support has been shown to serve as a protective factor for HIV viral load suppression in other populations, scant research has examined this relationship among men who have sex with men (MSM) in the United States. We assessed characteristics of social support, effects of social support on HIV viral load, and moderation by social support of the relationship between psychosocial indicators of a synergistic epidemic (syndemic) and HIV viral load. We analyzed longitudinal data from HIV-positive MSM using antiretroviral therapy who were enrolled in the Multicenter AIDS Cohort Study between 2002 and 2009 (n = 712). First, we conducted reliability assessments of a one-item social support measure. Then, we conducted a series of generalized longitudinal mixed models to assess our research questions. Moderation was assessed using an interaction term. A three-level (low/medium/high) social support variable demonstrated high reliability (intraclass correlation coefficients  = 0.72; 95% CI: 0.70, 0.75). Black and Hispanic MSM reported lower social support than their White counterparts (p social support (p social support (p social support levels were associated with greater viral load suppression and lower viral load means (p Social support moderated the relationships between syndemic and HIV viral load (p social support.

    Full Text Available Background: Routine immunization (RI is a key child survival intervention. Ensuring acceptable standards of RI service delivery is critical for optimal outcomes. Accumulated evidences suggest that ‘supportive supervision’ improves the quality of health care services in general. During 2009–2010, the Government of Odisha and UNICEF jointly piloted this strategy in four districts to improve RI program outcomes. The present study aims to assess the effect of this strategy on improvement of skills and practices at immunization session sites. Design: A quasi-experimental ‘post-test only’ study design was adopted to compare the opinion and practices of frontline health workers and their supervisors in four intervention districts (IDs with two control districts (CDs. Altogether, we interviewed 111 supervisor–supervisee (health worker pairs using semi-structured interview schedules and case vignettes. We also directly observed health workers’ practices during immunization sessions at 111 sites. Data were analyzed with SPSS version 16.0. Results: The mean knowledge score of supervisors in CDs was significantly higher than in intervention groups. Variegated responses were obtained on case vignettes. The control group performed better in solving certain hypothetically asked problems, whereas the intervention group scored better in others. Health workers in IDs gave a lower rating to their respective supervisors’ knowledge, skill, and frequency of supervision. Logistics and vaccine availability were better in CDs. Conclusion: Notwithstanding other limitations, supportive supervision may not have independent effects on improving the quality of immunization services. Addressing systemic issues, such as the availability of essential logistics, supply chain management, timely indenting, and financial resources, could complement the supportive supervision strategy in improving immunization service delivery.

    A novel d!sphase supplying supported liquid membrane (DSSLM), containing supplying feed phase andsupplying stripping phase tor transport behavior ot NI(Ⅱ), have been studied. The supplying supported feed phase included feed solution and di(2-ethyhexyl) phosphoric acid (HDEHP) as the carrier in kerosene, and supplying stripping phase included HDEHP as the cartier in kerosene and HC1 as the stripping agent. The effects of volume ratio of membrane solution to feed solution (O/F), pH, initial concentration of Ni(Ⅱ) and ionic strength in the feedsolution, volume ratio of membrane solution to stripping solution (O/S), concentration of H2SO4 solution, HDEHP concentration in the supplying stripping phase on transport of Ni(/I), the advantages of DSSLM compared to the traditional supported liquid membrane (SLM), the system stability, the reuse of membrane solution and the reten- tion of membrane phase were studied. Experimental results indicated that the optimum transpgrt of Ni(Ⅱ) was oh-tained when H2SO4 concentration was 2.00 mol'L-', HDEHP concentration was 0.120 mol·L-1, and O/S was 4· 1 in the supplying stripping phase, O/F was 1 : 10 and pH was 5.20 in the supplying feed phase. The ionic strength in supplying feed phase had no obvious effect on transport of Ni(Ⅱ). When initial Ni(Ⅱ) concentration was 2.00x 10-4 mol/L, the transport percentage of Ni(Ⅱ) was up to 93.1% in 250 min. The kinetic equation was deduced in terms of the law of mass diffusion and the interface chemistry.

    Family caregivers provide essential support as stroke survivors' return to community living, but it is not standard clinical practice to prepare or provide ongoing support for their care-giving role. In addition, health care professionals (HCPs) experiences with providing support to caregivers have not been explored previously. The objectives of this qualitative study were to: (1) explore the support needs over time from the perspective of caregivers, (2) explore the support needs over time from the perspective of HCPs, and (3) compare and contrast caregivers' and HCPs' perspectives. A qualitative study with stroke family caregivers (n = 24) and HCPs (n = 14). In-depth interviews were audio taped, transcribed, and analyzed using Framework Analysis. Three main themes emerged concerning: (1) types and intensity of support needed; (2) who provides support and the method of providing support; and (3) primary focus of care. These themes are discussed in relation to the TIR framework. Caregivers' needs for support and the individuals most suited to providing support change across the stroke survivor's recovery trajectory. Changes to service delivery to better support caregivers may include: (1) addressing caregivers' changing needs across the care continuum; (2) implementing a family-centered model of care; and (3) providing 7-day per week inpatient rehabilitation.

    Patients who have lost moderate posterior tooth support may also lose clenching force as a result of sensitivity to increased loading to the remaining teeth and possibly a loss of muscle strength, because clenching forces are limited to avoid stress to the remaining teeth. Few studies have correlated moderate posterior tooth loss with maximum clenching force. The purpose of this pilot study was to test the hypothesis that moderate loss of posterior tooth support will have a significant effect on maximum clenching force. The maximum clenching force of 44 adults, ages 28 to 76 (mean 46), with posterior tooth loss was compared with the maximum clenching force of a control group of 20 healthy full dentition adults, ages 18 to 55 (mean 30), by use of a bilateral strain-gauged transducer. The transducer consisted of 2 stainless steel plates separated by a steel sphere that balanced occlusal forces between right and left sides. Acrylic resin pads were fabricated for each patient to protect the cusps of the teeth. The overall accuracy was found to be within 2.3% of full scale over a range of 0 to 4000 N (0 to 900 lbs). The calibration reliability of the system was checked frequently by use of a dead weight of 222 N (50 lbs). Clenching forces were supported by first and second molars and second premolars when possible. The instrumentation, methods, and operator were the same for both groups. A 2-tailed Student t test (alpha=0.01) and a pooled estimate of the mean were used to determine possible statistical significance. To test for possible correlations between clenching force and lost tooth support and between clenching force and age, a linear regression correlation coefficient R was calculated. For the 44 subjects with posterior tooth loss, the mean clenching force was 462 N (104 lbs), with a range of 98 to 1031 N (22 to 232 lbs). This compares with a mean of 720 N (162 lbs) with a range of 244 to 1243 N (55 to 280 lbs) for the full-dentition subjects. A 2-tailed t test

    An atomic database is a collection of detailed and archival data primarily used to support a decision support system (DSS). Typically, atomic data are generated externally from other sources. In order to build an atomic data base in which data represent the information the DSS users expect, detailed data requirements must be specified to the source system. The basic types of information a source system needs are a list of required data items, the frequency and terms of data needs, and the method of interface. A detailed list of required items recommended for inclusion in any specifications of external data requirements is presented in this paper. Because of the volume of information involved in such specifications, a matrix presentation is believed to be the best organizational format to describe the requirements concisely and precisely. The specifications of external data requirements written for the Worldwide Household Goods Information System for Transportation Modernization (WHIST-MOD) project for the Personal Property Directorate (MTPP) of the Military Traffic Management Command (MTMC) are presented as a case study in this paper. It has been shown that the specifications in this case study effectively serve the objective of such a document. It is recommended that the concept presented in this paper be used as a guideline in specifying data requirements for an atomic database. 5 refs., 2 figs.

    Full Text Available Abstract Background The purpose of this study was to identify recommended practices for computerized clinical decision support (CDS development and implementation and for knowledge management (KM processes in ambulatory clinics and community hospitals using commercial or locally developed systems in the U.S. Methods Guided by the Multiple Perspectives Framework, the authors conducted ethnographic field studies at two community hospitals and five ambulatory clinic organizations across the U.S. Using a Rapid Assessment Process, a multidisciplinary research team: gathered preliminary assessment data; conducted on-site interviews, observations, and field surveys; analyzed data using both template and grounded methods; and developed universal themes. A panel of experts produced recommended practices. Results The team identified ten themes related to CDS and KM. These include: 1 workflow; 2 knowledge management; 3 data as a foundation for CDS; 4 user computer interaction; 5 measurement and metrics; 6 governance; 7 translation for collaboration; 8 the meaning of CDS; 9 roles of special, essential people; and 10 communication, training, and support. Experts developed recommendations about each theme. The original Multiple Perspectives framework was modified to make explicit a new theoretical construct, that of Translational Interaction. Conclusions These ten themes represent areas that need attention if a clinic or community hospital plans to implement and successfully utilize CDS. In addition, they have implications for workforce education, research, and national-level policy development. The Translational Interaction construct could guide future applied informatics research endeavors.

    Full Text Available How do students in a university degree programme make sense of their situation, and how can we as teachers support them in seeing their learning as a whole in relation to their main subject physics? This question is discussed first in relation to an empirical investigation of students’ ways of making sense of their study situation, and secondly draws on experience from two attempts to address issues emerging from that investigation. Based on the results we identify issues that potentially need addressing in many science and engineering programmes that are organised around a set of courses given by subject specialists and where students’ choices of courses are limited. These issues primarily concern the authority for learning, the development of a “physics knowledge object” as a programme goal, and the risk that students ended up only focussing on features of the courses’ organisation to give meaning to their studies. Finally, we discuss ways to support students’ sense making, as a process of learning for the “college of teachers” in such programmes.

    The HEALTHY study was a randomized, controlled, multicenter, middle school-based, multifaceted intervention designed to reduce risk factors for the development of type 2 diabetes. The study randomized 42 middle schools to intervention or control, and followed students from the sixth to the eighth grades. Participants were a racially, ethnically and geographically diverse cohort from across the United States. Here, we describe the conceptual underpinnings and design of the social marketing-based communications component of the HEALTHY study intervention that combined changes in the school nutrition and physical education (PE) environment with behavior change initiatives. The communications intervention component coordinated multiple elements to deliver campaigns that served to integrate and support all aspects of the HEALTHY intervention. The campaigns unfolded across five semesters of middle school, each targeting a specific theme related to the HEALTHY objectives. Communications campaigns comprised (1) core elements such as branding, posters, banners and visual and verbal messaging, (2) student events supporting the nutrition, PE and behavior intervention components through the application of social marketing and communications strategies, including the incorporation of student-generated media and (3) distribution of premiums and theme enhancers to extend the visibility of the study beyond the intervention environment. Formative research conducted with students, parents and school administrators was used to refine the communications strategy. Student peer communicators selected from the student body were involved to influence the normative student environment. Marketing and creative design experts developed a brand, logo, activities and materials.

    Aiming at the characteristics of the poor steady ability, the short stable time and severe deformation behavior of weakly cemented soft surrounding rock around extraction roadway, a bolt–cable combined supporting technology was proposed. Numerical simulation was performed by using FLAC3D software to study the effects of different supporting systems. The simulation result proves that those supporting systems have good practical values. Based on real-time monitoring and analysis of the deformation of surrounding rock and the stress of supporting structure, real time information of deformation of sur-rounding rock and stress state of supporting structure of extraction roadway within weakly cemented strata was obtained. Monitoring results show that large deformation and failure of surrounding rock of extraction roadway within weakly cemented strata can be effectively controlled by the bolt–cable com-bined supporting technology, which ensures the long-term stability and safety of surrounding rock and supporting structure.

    There is increasing interest from academics and clinicians in harnessing smartphone applications (apps) as a means of delivering behavioral interventions for health. Despite the growing availability of a range of health-related apps on the market, academic research on the development and evaluation of such apps is in the relatively early stages. A few existing studies have explored the views of various populations on using mobile phones for health-related issues and some studies are beginning to report user feedback on specific apps. However, there remains little in depth research on users' (and potential users') experiences and views on a wide range of features and technologies that apps are, or will soon be, capable of. In particular, research on young adults is lacking, which is an unfortunate omission considering that this group comprises of a good number of mobile technology adoptors. The current study sought to explore young adults' perspectives on apps related to health behavior change. It sought their experiences and views of features that might support health behavior change and issues that contribute to interest in and willingness to use such apps. Four focus groups were conducted with 19 students and staff at a University in the United Kingdom. Participants included 13 females and 6 males with a mean age of 23.79 (SD 7.89). The focus group discussions centred on participants' experiences of using smartphone apps to support a healthy lifestyle, and their interest in and feelings about features and capabilities of such apps. The focus groups were recorded, transcribed, and analyzed using inductive thematic analysis. Study findings suggested that young, currently healthy adults have some interest in apps that attempt to support health-related behavior change. Accuracy and legitimacy, security, effort required, and immediate effects on mood emerged as important influences on app usage. The ability to record and track behavior and goals and the ability to

    Background and Aims: Self-monitoring of blood glucose (SMBG) is associated with improved glycemic control among patients with type 2 diabetes, however, the practice of daily self-monitoring is not optimal. Telecommunications technology may improve adherence to recommended self-management practices by remotely transmitting automated reminders to motivate patients, and utilizing social networking for peer support. The purpose of this pilot study is to demonstrate the feasibility and usability of mobile technology and the potential added value of social support to improve SMBG frequency and glycemic control among adults with type 2 diabetes. Methods: Adults 25–74 years of age with type 2 DM and an average HbA1c > 8.0% were recruited from Kaiser Permanente Georgia (KPGA) and Oakhurst Medical Center (OMC, a community health clinic) to participate in a 3-month study using wireless technology. Enrollment sessions with presentations on SMBG techniques, use of the wireless technology, and motivational coaching to enhance social support were conducted in November 2009. During the subsequent 3-months, both diabetes patients and their self-selected supporters will receive text messages to their cell phones summarizing a patient’s SMBG frequency and levels. Participants and their supporters will attend a disenrollment session in February 2010 when feasibility and usability will be assessed in focus groups. Results: 6 of 161 eligible diabetes patients at KPGA and 9 of 28 eligible diabetes patients at OMC, and their self-selected supporters, consented to participate. The average age of diabetes patients was 49.3 years. 86.7% (N=13) were African-American; and 33.3% (N=5) were male. Five days after enrollment, 60% (N=9) of patients had connected their wireless transmitters and had current blood glucose data. Follow-up phone calls will be made to ensure that all participants are connected to the wireless technology within 10 days of the enrollment session. Conclusion

    Full Text Available One of the important learning objectives of our bachelor course on "Techniques in Decision Support Systems" is to develop understanding of core decision making process in real-life business situations. The conventional teaching methods are unable to explain complexities of real-life business. Although the classroom discussions can be effective to understand general factors, such as opportunity cost, return on investment, etc. affecting business decisions, the effects of factors like dynamic business environment, incomplete information, time pressure etc. can not be truly explained through such simple discussions. In this paper, we describe our experience of adopting student-centered, role-based, case study to deal with this situation. The interactive case-based study not only provided students with experiential learning, but also gave them liberty to test their thoughts. As a result, we observed improved students' learning as well as improved grades. In addition, this approach made classes more dynamic and interesting.

    Major depression is a highly prevalent and severe mental disease. Despite the effective treatment options available, the risk of relapse is high. Interventions based on information and communication technologies generate innovative opportunities to provide support to patients after they completed treatment for depression. This acceptability study evaluated the Internet-based program Apoyo, Seguimiento y Cuidado de Enfermedades a partir de Sistemas Operativos (ASCENSO) in terms of its feasibility and acceptability in a sample of 35 patients in Chile. The study reveals high rates of acceptance and satisfaction among patients who actively used the program. As obstacles, patients mentioned technical problems, a lack of contact with other participants, and an insufficient connection between the program and the health service professionals. ASCENSO appears to be a promising complement to regular care for depression. Following improvements of the program based on participants' feedback, future research should evaluate its efficacy and cost-effectiveness.

    2012-02-01

    The kinetics of the catalytic hydrogenation of d-glucose to produce d-sorbitol was studied in a three-phase laboratory scale reactor. The hydrogenation reactions were performed on activated charcoal supported platinum catalyst in the temperature range 25-65°C and in a constant pressure of 1 atm. The kinetic data were modeled by zero, first and second-order reaction equations. In the operating regimes studied, the results show that the hydrogenation reaction was of a first order with respect to d-glucose concentration. Also the activation energy of the reaction was determined, and found to be 12.33 kJ mole-1. A set of experiment was carried out to test the deactivation of the catalyst, and the results show that the deactivation is slow with the ability of using the catalyst for several times with a small decrease in product yield.

    To review the qualitative and quantitative evidence of the benefits of peer support for parents of children with disabling conditions in the context of health, well-being, impact on family, and economic and service implications. We comprehensively searched multiple databases. Eligible studies evaluated parent-to-parent support and reported on the psychological health and experience of giving or receiving support. There were no limits on the child's condition, study design, language, date, or setting. We sought to aggregate quantitative data; findings of qualitative studies were combined using thematic analysis. Qualitative and quantitative data were brought together in a narrative synthesis. Seventeen papers were included: nine qualitative studies, seven quantitative studies, and one mixed-methods evaluation. Four themes were identified from qualitative studies: (1) shared social identity, (2) learning from the experiences of others, (3) personal growth, and (4) supporting others. Some quantitative studies reported a positive effect of peer support on psychological health and other outcomes; however, this was not consistently confirmed. It was not possible to aggregate data across studies. No costing data were identified. Qualitative studies strongly suggest that parents perceive benefit from peer support programmes, an effect seen across different types of support and conditions. However, quantitative studies provide inconsistent evidence of positive effects. Further research should explore whether this dissonance is substantive or an artefact of how outcomes have been measured. © The Authors.

    There is ample evidence that social support is protective against posttraumatic stress (PTS) symptoms through social causation processes. It is also likely that PTS is associated with decreased social support through social selection processes. Few studies, however, have examined the longitudinal and bidirectional associations between social support and PTS in a postdisaster context, and whether such associations vary by type of support (e.g., emotional, informational, or tangible). We examined these relationships using Galveston Bay Recovery Study data. Participants (N = 658) were interviewed 2-6 months (W1), 5-9 months (W2), and 14-19 months (W3) after Hurricane Ike in 2008. Longitudinal relationships between each support type and PTS were examined in cross-lagged models. W1 emotional support was negatively associated with W2 PTS (Estimate = -.13, p = .007), consistent with social causation. W1 PTS was negatively associated with W2 emotional support (Estimate = -.14, p = .019), consistent with social selection. In contrast, pathways were nonsignificant at subsequent waves and for informational and tangible support. Results suggested that postdisaster social causation and selection were limited to emotional support and diminish over time. Based on these findings, postdisaster services should emphasize restoring supportive social connections to minimize the psychiatric consequences of disaster, especially among those with prior evidence of distress.

    Social well-being is one of the important aspects of health. In fact, this is a reflection of experience in a social environment, indicating how social challenges are determined. In other words, social well-being is an explanation of people's perception and experience of being in a good situation, satisfaction with the structure, and social interaction. This qualitative study intended to explore nurses' experience of social well-being. Qualitative content analysis was used to conduct the study. Through purposive sampling, a total of 18 nurses with various clinical experiences participated in semi-structured interviews. The data were analysed using the five-step, qualitative content analysis introduced by Graneheim and Lundman. The main theme extracted from the data analysis was "thirst for a holistic support" in nurses. It consisted of two subthemes including internal support (family's support, colleague's support, and organizational support) and external support (society's support and media's support). Nurses' experiences in shaping their social well-being show that nurses need support in order to rebuild their social well-being. It is supported in partnership with the media, the community, health-related organizations, and by nurses and family. This improves job satisfaction, hope, motivation, commitment, and confidence so as to ultimately facilitate improvement of social well-being of nurses.

    The torus & cryostat cryoline of ITER cryodistribution system has been designed as per the process specifications. The cryoline is an ensemble of six process pipes, thermal shield, fixed, sliding support and outer jacket. The fixed support (FS), which also acts as the anchor for the bellows, is one of the most important part of the cryoline. The FS has to withstand the static weight of pipes as well as the spring and thrust forces arising from the bellows. The FS design has been optimized for the thermal, structural and for combined loads with thermal optimization criteria; less than 8 Watt at 100 K and less than 1.5 Watt at 4.5 K. ANSYS 10.0 has been used for the analysis and CATIA V5 R16 has been used for the modelling as well as geometry optimization. In order to bring the Von-Mises stress within the acceptable limit of 115 MPa, a detailed mesh sensitivity study has been carried out along with design optimization. The iterative process of mesh refinement continued till stress convergence is achieved. The stress analysis has been carried out for optimized mesh size. The paper will present the design methodology, construction details and the results of the analysis.

    Regular review and support for asthma self-management is promoted in guidelines. A randomised controlled trial suggested that unscheduled health care usage was similar when patients were offered self management support by a lay-trainer or practice nurses. Following the RCT, a costing study was undertaken using the trial data to account for the cost of delivery of the service under both strategies and the resulting impact on unscheduled healthcare (measure of effectiveness) in this trial. One year data (n = 418) showed that 29% (61/205) of the nurse group required unscheduled healthcare (177 events) compared with 30.5% (65/213) for lay-trainers (178 events).The training costs for the lay-trainers were greater than nurses (£36 versus £18 respectively per patient, pnurses (£6 per patient versus £24, pnurses is £161, and £135 for lay-trainers (mean difference £25, [95% CI = -£97, £149, p = 0.681]). The total costs (delivery and unscheduled healthcare) were £202 per patient for nurses versus £178 for lay-trainers, (mean difference £24, [95%CI = -£100, £147, p = 0.707]). There were no significant differences in the cost of training and healthcare delivery between nurse and lay trainers, and no significant difference in the cost of unscheduled health care use.

The FS has to withstand the static weight of pipes as well as the spring and thrust forces arising from the bellows. The FS design has been optimized for the thermal, structural and for combined loads with thermal optimization criteria; less than 8 Watt at 100 K and less than 1.5 Watt at 4.5 K. ANSYS 10.0 has been used for the analysis and CATIA V5 R16 has been used for the modelling as well as geometry optimization. In order to bring the Von-Mises stress within the acceptable limit of 115 MPa, a detailed mesh sensitivity study has been carried out along with design optimization. The iterative process of mesh refinement continued till stress convergence is achieved. The stress analysis has been carried out for optimized mesh size. The paper will present the design methodology, construction details and the results of the analysis.

    To describe levels of fatigue and explore clinical factors that might contribute to fatigue in critically ill patients receiving mechanical ventilation. Descriptive, correlational design. Sample was a sub-set of patients enrolled in a randomised clinical trial testing patient-directed music for anxiety self-management. Clinical factors included age, gender, length of ICU stay, length of ventilatory support, illness severity (APACHE III), and sedative exposure (sedation intensity and frequency). Descriptive statistics and mixed models were used to address the study objectives. Medical and surgical intensive care units in the Midwestern United States. Fatigue was measured daily via a 100-mm Visual Analogue Scale, up to 25 days. A sample of 80 patients (50% female) receiving ventilatory support for a median 7.9 days (range 1-46) with a mean age of 61.2 years (SD 14.8) provided daily fatigue ratings. ICU admission APACHE III was 61.5 (SD 19.8). Baseline mean fatigue ratings were 60.7 (SD 27.9), with fluctuations over time indicating a general trend upward. Mixed models analysis implicated illness severity (β(se(β))=.27(.12)) and sedation frequency (β(se(β))=1.2(.52)) as significant contributors to fatigue ratings. Illness severity and more frequent sedative administration were related to higher fatigue ratings in these mechanically ventilated patients. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available We evaluate the efficacy-safety of percutaneous vertebroplasty (PV as primary treatment in adult degenerative scoliosis. During the last 4 years, PV was performed in 18 adult patients (68 vertebral bodies with back pain due to degenerative scoliotic spine. Under anaesthesia and fluoroscopy, direct access to most deformed vertebral bodies was obtained by 13G needles, and PMMA for vertebroplasty was injected. Scoliosis’ inner arch was supported. Clinical evaluation included immediate and delayed studies of patient’s general condition and neurological status. An NVS scale helped assessing pain relief, life quality, and mobility improvement. Comparing patients’ scores prior to (mean value 8.06±1.3 NVS units, the morning after (mean value 3.11±1.2 NVS units, at 12 (mean value 1.67±1.5 NVS units, and 24 months after vertebroplasty (mean value 1.67±1.5 NVS units treatment, patients presented a mean decrease of 6.39±1.6 NVS units on terms of life quality improvement and pain relief (P=0.000. Overall mobility improved in 18/18 (100% patients. No complications were observed. During follow-up period (mean value 17.66 months, all patients underwent a mean of 1.3 sessions for facet joint and nerve root infiltrations. Percutaneous vertebroplasty in the inner arch seems to be an effective technique for supporting adult degenerative scoliotic spine.

    Managing combined sewage systems in large cities discharging to coastal waters, often bearing recreational activities, remains a challenge. Studying the impacts of such discharges requires the development of specific models. Hydrodynamic and water quality modelling of coastal waters employs numerical methods and algorithms, leading to the design of complex models which require expert use. The use of such models as decision support tools to simulate discharge impacts and define adequate corrective measures could represent a key part in meeting this challenge. In this paper, the authors describe the work undertaken to develop an operational decision support system (ODSS) methodology aiming to enable wastewater utilities' non-expert staff to carry out user-friendly scenario analysis based on computational fluid dynamics simulations. This article depicts the application and validation of the ODSS to the combined sewage system and the Tagus estuary of the city of Lisbon in Portugal. The ODSS was used for simulating the effects in the receiving coastal waters of a discharge caused by a scheduled maintenance operation in the sewage infrastructure. Results show that the use of such ODSS by non-expert staff increases their decision capabilities and knowledge of the wastewater utility's contribution to reducing negative impacts of sewage discharges on the receiving water bodies.

    Community supported agriculture (CSA) programs have become a viable source of locally produced foods and represent a new way to increase fruit and vegetable consumption among individuals. Because CSAs represent a way for consumers to acquire healthy foods while providing financial support to local farmers, CSA involvement could reflect, and be related to, greater concern with both health and environmental impact of food choice. As such, the aim of this study was to examine whether ecological attitudes of CSA members could predict food- and sustainability-related behaviours. Using an online survey, respondents answered questions about attitudes towards the environment, as well behaviours related to food purchases, family food preparation, composting, recycling and minimising food-packaging waste. A total of 115 CSA member responses were collected. Ordinary least squares (OLS) multivariate regression analysis was used to investigate the predictive validity of environmental attitudes on measures of behaviours. A large portion of participants reported the amount and variety of fruits and vegetables their households ate increased as a result of joining a CSA program. Ecological sensitivity was a significant predictor of sustainability-related behaviours as well as money spent eating out and times eaten away from home per week. However, it was not predictive of family involvement in home food preparation.

    Full Text Available The dynamic behaviour of a double-helical gear system supported by journal bearings is theoretically and experimentally investigated in this study. A bending–torsional–axial coupling model for dynamic analysis of double-helical gear system is developed. Influence of the time-varying mesh stiffness and damping is considered. Oil film stiffness and damping of the supporting journal bearing are supposed to be time-varying, and the time-varying oil film stiffness and damping are predicted by a back propagation neural network, which is optimized by genetic algorithm. A double-helical gear–rotor–journal bearing system test rig is also established to carry out the experimental investigations, such as the dynamic transmission errors of gear pairs. The comparisons between theoretical and experimental results show that the time-varying oil film dynamic coefficients of journal bearings are an important internal excitation. The theoretical model with time-varying oil film stiffness and damping can predict the gear dynamics more accurate than the model with time-invariant oil film stiffness and damping, and the neural network optimized by genetic algorithm can obtain the time-varying oil film stiffness and damping efficiently and accurately for the dynamic analysis of double-helical gear system.

    2009-07-01

    Full Text Available Abstract Background There is increasing evidence that the environment plays a role in influencing physical activity in children and adults. As children have less autonomy in their behavioural choices, neighbourhood environment supportiveness may be an important determinant of their ability to be active. Yet we know rather little about the types of environment that children use for bouts of physical activity. This study uses accelerometery and global positioning system technologies to identify the charactieristics of environments being used for bouts of continuous moderate to vigorous physical activity (MVPA in a sample of English schoolchildren. Methods The study used a convenience sample of 100 children from SPEEDY (Sport, Physical activity and Eating behaviour: Environmental Determinants in Young people, a cohort of 2064 9–10 year-olds from Norfolk, England, recruited in 2007. Children wore an ActiGraph GT1M accelerometer and a Garmin Forerunner 205 GPS unit over four consecutive days. Accelerometery data points were matched to GPS locations and bouts (5 minutes or more of MVPA were identified. Bout locations were overlaid with a detailed landcover dataset developed in a GIS to identify the types of environment supporting MVPA. Findings are presented using descriptive statistics. Results Boys were also more active than girls, spending an average of 20 (SD 23 versus 11 (SD 15 minutes per day in MVPA bouts. Children who spent more time outside the home were more active (p = 0.002, especially girls and children living in rural locations (both p Conclusion The study has developed a new methodology for the identification of environments in which bouts of continuous physical activity are undertaken. The results highlight the importance of the provision of urban gardens and greenspaces, and the maintenance of safe street environments as places for children to be active.

    ABSTRACT: BACKGROUND: Deliberate self harm (DSH) is a major public health concern and has increased among young people in Ireland. While DSH is undoubtedly the result of interacting factors, studies have identified an association between DSH and family dysfunction as well as the protective role of positive family relationships. Following a focus group meeting held to identify the needs of parents and carers of young people with DSH, a support programme (SPACE) was developed. The aims of the current study are to evaluate the effectiveness of the SPACE programme in decreasing parental psychological distress, reducing parental report of young peoples\\' difficulties, increasing parental satisfaction and increasing parents\\' ratings of their own defined challenges and goals. METHODS: Participants were recruited from a Mental Health Service within a paediatric hospital, Community Child and Adolescent Mental Health Teams and family support services. All services were located within the greater Dublin area in Ireland. Forty-six parents of children who had engaged in or expressed thoughts of self harm attended the programme and participated in the evaluation study. The programme ran once a week over an 8-week period and included topics such as information on self harm in young people, parenting adolescents, communication and parental self-care. Seventy percent (N = 32) of the original sample at Time 1 completed measures at Time 2 (directly following the programme) and 37% (N = 17) of the original sample at Time 1 completed them at Time 3 (6 months following the programme).A repeated measures design was used to identify changes in parental wellbeing after attendance at the programme as well as changes in parental reports of their children\\'s difficulties. RESULTS: Participants had lower levels of psychological distress, increased parental satisfaction, lower ratings of their own defined challenges and higher ratings of their goals directly after the programme.

    A variety of surface spectroscopic techniques, coupled with chemical activity measurements, has been used to study supported heterogeneous catalysts. The catalytic systems investigated are: Ni on Al/sub 2/O/sub 3/ and SiO/sub 2/, Co on Al/sub 2/O/sub 3/, Co and Zn on Al/sub 2/O/sub 3/, Mo on Al/sub 2/O/sub 3/, Mo in TiO/sub 2/, W on Al/sub 2/O/sub 3/, Co and Mo on Al/sub 2/O/sub 3/ and Ni and W on Al/sub 2/O/sub 3/. Emphasis has been on defining the nature of the surface species on the oxidic catalysts, prior to treatment or activation. Reaction of catalysts with H/sub 2/ and H/sub 2/S/H/sub 2/ have been used for diagnosing different species. Treatment with Ha2S/H/sub 2/ also has been used to elucidate the species on sulfided hydrotreating catalysts. Other aspects of the research involved evaluation of photoacoustic spectroscopy for studying catalysts and use of curve resolving techniques to maximize use of ESCA spectra for studying catalysts. In general, the species on catalysts with loadings below monolayer coverage are determined by the nature of the support. For example, on ..gamma..-Al/sub 2/O/sub 3/ distributions of the metal between tetrahedral (Td) and octahedral (Oh) sites occurs. Reactivity of metals in Oh and Td support sites differ; in Mo-Al/sub 2/O/sub 3/ catalysts, the metal in Td sites is reduced only to Mo(+5) by H/sub 2/ (500/sup 0/C) but Oh Mo is reduced to Mo(+4). Sulfiding Mo/Al/sub 2/O/sub 3/ catalysts produces MoS/sub 2/ but leaves some metal unsulfided (Mo+5). Clear evidence for interaction species was found for ternary catalyst systems, viz. Co-Mo-Al/sub 2/O/sub 3/.

    A series of bi-metallic Pd-Pt catalysts supported on both pristine and fluorinated alumina supports were investigated with x-ray absorption spectroscopy. It was found that Pd and Pt form small alloy particles on the pristine alumina support; the composition and the cluster size of the PdPt bimetallic alloys, and the electronic properties of the metals were significantly altered on the fluorinated support. The remarkable increase in sulfur tolerance of the PdPt metallic clusters supported on the fluorine pretreated alumina can be attributed to an electronic depletion of the metals, large particle size and direct participation of the acid sites in the reaction.

    During the machining of large aperture lightweight space mirror, the mirror figure consistency between ground test and space mission is a problem. In order to effectively control the supporting deformation effect on test results in gravity environment, in view of a 1.2-m space mirror with back blind holes, a supporting method for optical axis horizontal test is proposed, with this method, mirror under test is positioned by three center hole surfaces and supported by six external hole surfaces. The effect of deformation caused by different supporting force value, area and position is analyzed by finite element method, the simulation results show that this supporting method can control the mirror supporting deformation within PV0.035λ rms0.005λ. The actual supporting system uses soft expansion mandrel to control the mirror position and pneumatic lever to realize the floating support. In order to ensure that the support force can evenly distribute on the contact surface, a pressure mapping system is adopted to measure the interface pressure between the mirror blind holes and the soft supporting pads for the first time. This method can meet the test requirements of rms=1/40λ mirror and provides a technical support for high precision test of large aperture space mirror with back blind holes.

  14. Study on Chemisorption, Catalytic Behavior, and Stability of Supported Au Catalyst for the Propylene Epoxidation Reaction

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The supported Au/TiO2 and Au/TiO2-SiO2 catalysts were prepared by deposition precipitation method. The TPD study reveals that propylene oxide competes with propylene to be adsorbed on the same adsorptive center-Tin+ site on the surface of the catalyst and that the adsorbing capacity of the catalyst for propylene oxide is larger than that for propylene. Catalytic behavior for propylene epoxidation with H2 and O2 was tested in a micro-reactor. Under typical conditions, the selectivity for propylene oxide is over 87%. The TG curves show that PO successive oxidation cause carbon deposition on the active center and deactivation of the Au catalysts. Because the amounts of Tin+ site decrease significantly, and consequently the separation between Tin+ sites increases, the Au/TiO2-SiO2 catalyst is more stable than Au/TiO2.

    2016-02-01

    Resilience, or the process of adjusting well to risk, relies on constructive collaboration between youths and their social ecologies. Although the literature details the risks of an intellectual disability (ID), there is little explanation of why some young people cope well despite these risks. Accordingly, we report a multiple case study that affords insight into the resilience of 24 adolescents with ID. Using a draw-and-talk methodology, these young people explained their resilience as enabled primarily by supportive social ecologies (which facilitated behavioral and emotional regulation, encouraged mastery, treated them as agentic beings, and offered safe spaces). Adolescents' positive orientation to their life-worlds co-facilitated their resilience. These insights advance effective ways to champion the resilience of young people with ID.

    Bimetallic platinum-copper nanoparticles on carbon support are studied as a perspective electrochemical catalyst by anomalous small-angle X-ray scattering near the Pt absorption L3-edge. The simultaneous fitting of several diffraction patterns measured at different photon energies lead to a satisfactory agreement between experimental and model curves in the assumption of core-shell structure of the particles with Pt-rich shell and Cu-rich core. It is shown that the average size of as prepared nanoparticles is about 6 nm with distribution spread of about ±2 nm and with thickness of Pt-rich shell approximately 1.6 nm. After annealing at 350o C the average size of the particles increased by two times with additional enlargement of the Pt-rich shell thickness.

    Regularly grown Pt particles supported by amorphous SiO{sub 2} were heated in hydrogen at 873 K after an oxidising treatment. The morphological and structural changes were studied by electron microscopy. Platinum silicides Pt{sub 3}Si with L1{sub 2} (Cu{sub 3}Au) structure, monoclinic Pt{sub 3}Si and tetragonal Pt{sub 12}Si{sub 5} were identified after the treatment. The mechanisms of coalescence of the particles and the formation of irregular large particles are suggested. A topotactic structural transformation accompanied with the migration of Si from the substrate to the particles are suggested to take place during Pt{sub 3}Si formation.

    Full Text Available The production of pure carbon spheres was achieved in the absence of a catalyst through the direct pyrolysis of two hydrocarbon sources, acetylene and ethylene. Systematic studies using acetylene as the feedstock indicated that the size distribution of the resulting carbon microspheres can be controlled by pyrolysis temperature, time and feedstock flow rate. The resulting spheres were fully characterised by transmission electron microscopy (TEM and thermogravimetric analysis. The TEM examination showed that these spheres have a ball-like and chain-like morphology, and the balls have smooth surfaces with a variation in diameter size and distribution determined by the reaction conditions. Carbon microsphere-supported cobalt catalysts were synthesised and have shown good activity in the ethylene hydrogenation reaction.

    A study of community leaders was undertaken in Hartsville, Tennessee, site of the TVA Hartsville Nuclear Power Plant currently under construction. Leaders were found to be extremely supportive of the plant and of TVA's efforts to mitigate impacts expected to result from construction. Like their citizen counterparts, leaders expect economic benefits and some growth-related disruption to occur as a result of the plant, while environmental impacts are seen as extremely unlikely to occur. Plant-related issues, such as housing availability and traffic congestion, dominate leaders' thinking about current issues. These issues are expected to continue to be important in the future, and new issues dealing with growth and planning, employment and taxation are expected to arise.

    The need to reform ineffective or harmful public subsidies has long been recognised and has been a contentious point of discussion for several years. The EU has a long-standing commitment to removing or phasing out environmentally harmful subsidies (EHS). Most recently, the need to phase out EHS is reiterated in the 'Roadmap for a resource efficient Europe' which includes a milestone that 'by 2020 EHS will be phased out, with due regard to the impact on people in need'. Despite several commitments, progress has been slow and subsidies remain an issue in most EU countries. This study focuses specifically on EHS at the level of EU Member States; it identifies key types of EHS and examines cases of existing EHS across a range of environmental sectors and issues, including subsidies from non-action. The study also analyses examples of good practices in the reform of EHS in EU Member States and the lessons that can be learnt from these cases. Finally, based on this analysis, it develops practical recommendations on phasing out and reforming EHS to support the objectives of the Europe 2020 Strategy and the resource efficiency agenda. The study was carried out between January and October 2012 and is based on an analysis of literature and consultation with experts and policy makers. The sectoral cases studied are listed and discussed in this annex report: agriculture, climate and energy, fisheries, food, forestry, materials, transport, waste, and water.

    This initial study examined a therapist-led, synchronous, online support group (OSG) with psycho-education (OSG + E) compared to self-help psycho-education (E). The study aims were to examine proof of concept-feasibility, acceptability, and usefulness-and to hone methods for a formal RCT. One hundred five young breast cancer survivors (<50 years) post-treatment were randomized either to OSG + E or E. OSG + E received a therapist-led 10-week synchronous online intervention. E received a self-help workbook. Assessments were at baseline, 10 weeks, and 3 months, with willing OSG + E members completing post-study interviews. Researchers used inductive analysis, generating qualitative themes for feasibility, acceptability, and usefulness. We examined trajectories for one primary and two secondary quantitative outcomes and a combined moderator to discover who preferentially benefitted from the intervention. Qualitative analyses revealed that synchronous chat was at times challenging, but minimal technical coaching, structure, set topics, and professional facilitation enabled conversations that were focused and meaningful. A combined moderator indicated that generally more women benefitted from OSG + E relative to E and particularly those women in semi-rural and rural areas. This study suggests that therapist-led synchronous OSGs are feasible, acceptable, and useful for young breast cancer survivors and that a future RCT with a larger sample size, perhaps more focused on non-urban areas, is needed to establish its effectiveness.

    Riverside Technology, inc. has developed a Climate Change Decision Support System (DSS) to provide water managers with a tool to explore a range of current Global Climate Model (GCM) projections to evaluate their potential impacts on streamflow and the reliability of future water supplies. The system was developed as part of a National Oceanic and Atmospheric Administration (NOAA) Small Business Innovation Research (SBIR) project. The DSS uses downscaled GCM data as input to small-scale watershed models to produce time series of projected undepleted streamflow for various emission scenarios and GCM simulations. Until recently, water managers relied on historical streamflow data for water resources planning. In many parts of the country, great effort has been put into estimating long-term historical undepleted streamflow accounting for regulation, diversions, and return flows to support planning and water rights administration. In some cases, longer flow records have been constructed using paleohydrologic data in an attempt to capture climate variability beyond what is evident during the observed historical record. Now, many water managers are recognizing that historical data may not be representative of an uncertain climate future, and they have begun to explore the use of climate projections in their water resources planning. The Climate Change DSS was developed to support water managers in planning by accounting for both climate variability and potential climate change. In order to use the information for impact analysis, the projected streamflow time series can be exported and substituted for the historical streamflow data traditionally applied in their system operations models for water supply planning. This paper presents a case study in which climate-adjusted flows are coupled with the U.S. Army Corps of Engineers (USACE) ResSim model for the Apalachicola, Chattahoochee, and Flint (ACF) River basins. The study demonstrates how climate scenarios can be used

    Psilocybin is a serotonin receptor agonist that occurs naturally in some mushroom species. Recent studies have assessed the therapeutic potential of psilocybin for various conditions, including end-of-life anxiety, obsessive-compulsive disorder, and smoking and alcohol dependence, with promising preliminary results. Here, we aimed to investigate the feasibility, safety, and efficacy of psilocybin in patients with unipolar treatment-resistant depression. In this open-label feasibility trial, 12 patients (six men, six women) with moderate-to-severe, unipolar, treatment-resistant major depression received two oral doses of psilocybin (10 mg and 25 mg, 7 days apart) in a supportive setting. There was no control group. Psychological support was provided before, during, and after each session. The primary outcome measure for feasibility was patient-reported intensity of psilocybin's effects. Patients were monitored for adverse reactions during the dosing sessions and subsequent clinic and remote follow-up. Depressive symptoms were assessed with standard assessments from 1 week to 3 months after treatment, with the 16-item Quick Inventory of Depressive Symptoms (QIDS) serving as the primary efficacy outcome. This trial is registered with ISRCTN, number ISRCTN14426797. Psilocybin's acute psychedelic effects typically became detectable 30-60 min after dosing, peaked 2-3 h after dosing, and subsided to negligible levels at least 6 h after dosing. Mean self-rated intensity (on a 0-1 scale) was 0·51 (SD 0·36) for the low-dose session and 0·75 (SD 0·27) for the high-dose session. Psilocybin was well tolerated by all of the patients, and no serious or unexpected adverse events occurred. The adverse reactions we noted were transient anxiety during drug onset (all patients), transient confusion or thought disorder (nine patients), mild and transient nausea (four patients), and transient headache (four patients). Relative to baseline, depressive symptoms were markedly reduced 1

    Cerebral function is associated with exceptionally high metabolic activity, and requires continuous supply of oxygen and nutrients from the blood stream. Since the mid-twentieth century the idea that brain energy metabolism is coupled to neuronal activity has emerged, and a number of studies supported this hypothesis. Moreover, brain energy metabolism was demonstrated to be compartmentalized in neurons and astrocytes, and astrocytic glycolysis was proposed to serve the energetic demands of glutamatergic activity. Shedding light on the role of astrocytes in brain metabolism, the earlier picture of astrocytes being restricted to a scaffold-associated function in the brain is now out of date. With the development and optimization of non-invasive techniques, such as nuclear magnetic resonance spectroscopy (MRS), several groups have worked on assessing cerebral metabolism in vivo. In this context, (1)H MRS has allowed the measurements of energy metabolism-related compounds, whose concentrations can vary under different brain activation states. (1)H-[(13)C] MRS, i.e., indirect detection of signals from (13)C-coupled (1)H, together with infusion of (13)C-enriched glucose has provided insights into the coupling between neurotransmission and glucose oxidation. Although these techniques tackle the coupling between neuronal activity and metabolism, they lack chemical specificity and fail in providing information on neuronal and glial metabolic pathways underlying those processes. Currently, the improvement of detection modalities (i.e., direct detection of (13)C isotopomers), the progress in building adequate mathematical models along with the increase in magnetic field strength now available render possible detailed compartmentalized metabolic flux characterization. In particular, direct (13)C MRS offers more detailed dataset acquisitions and provides information on metabolic interactions between neurons and astrocytes, and their role in supporting neurotransmission.

    In the framework of the French Act of 28 June 2006 about nuclear materials and waste management, a GEN IV and actinides incineration demonstration prototype is to be commissioned in the 2020 decade. In this objective a prototype called ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) is proposed to demonstrate the progress made in SFR technology at an industrial scale by qualifying innovative options, some of which still remain open in the areas requiring improvements, especially safety and operability. More specifically, we aim for a level of safety that is at least equivalent to that of the EPR (third generation), with improvements made in SFR-specific fields. The integration of safety issues in the early phase of the design of ASTRID is necessarily expected. For this purpose, CEA and its partners AREVA and EDF have planned to perform a level-1 PSA to support and orientate the preliminary design of ASTRID reactor. This paper presents the PSA approach and current studies for the assessment of safety systems and the future work to be done for the 2012-2014 period. The preliminary preparation of PSA studies is presented: objectives and scope of the early design phase PSA, definition of core damage states, selection and grouping of initiating events, assessment of safety functions and related systems. Work under progress is also presented: modelling of event trees, construction of fault trees of safety systems, transient calculations of accident sequences with the CATHARE2 code and reliability data assessment. Main objectives of a level-1 PSA performed at conceptual design stage are an early assessment of the safety architecture of the reactor and findings about the most effective areas for improvement, but also the identification of dominant accident sequences and comparison with alternative designs. After the elaboration of a simplified level-1 PSA model for nominal state and main internal initiators, various design alternatives will be

    The transport of Dy(Ⅲ) through a dispersion supported liquid membrane (DSLM) consisting of polyvinylidene fluoride mem-brane (PVDF) as the liquid membrane support and dispersion solution including HC1 solution as the stripping solution and 2-ethyl hexyl phosphonic aeid-mono-2-ethyl hexyl ester (PC-88A) dissolved in kerosene as the membrane solution, was studied. The effects of pH value, initial concentration of Dy(Ⅲ) and different ionic strength in the feed phase, volume ratio of membrane solution and stripping solution, con-centration of HC1 solution, concentration of carder, different stripping agents in the dispersion phase on transport of Dy(Ⅲ) were also inves-tigated, respectively. As a result, when the concentration of HCI solution was 4.0 mol/L, concentration of PC-88A was 0.10 mol/L, and vol-ume ratio of membrane solution and stripping solution was 40:20 in the dispersion phase, and pH value was 5.0 in the feed phase, the trans-port effect of Dy(Ⅲ) was the best. Ionic strength had no obvious effect on transport of Dy(Ⅲ). Under the optimum condition studied, when initial concentration of Dy(Ⅲ) was 0.8×10-4 mol/L, the transport rate of Dy(Ⅲ) was up to 96.2% during the transport time of 95 min. The kinetic equation was developed in terms of the law of mass diffusion and the theory of interface chemistry. The diffusion coefficient of Dy(Ⅲ) in the membrane and the thickness of diffusion layer between feed phase and membrane phase were obtained and the values were 1.99×10-7 m2/s and 15.97 μm, respectively. The results were in good agreement with experimental results.

    This report describes the qualitative component of a large-scale study of supported socialization. Paralleling the recent advances made through supported housing, supported employment, and supported education, this approach seeks to increase the involvement of individuals with psychiatric disabilities in naturally occurring social and recreational activities in community settings of their choice. After a review of social relationships and psychiatric disability, we describe the Partnership Project and present findings from a series of qualitative interviews conducted with a subsample of participants. We then discuss the implications of these findings for the community integration of individuals with psychiatric disabilities.

    Full Text Available Introduction: Social well-being is one of the important aspects of health. In fact, this is a reflection of experience in a social environment, indicating how social challenges are determined. In other words, social well-being is an explanation of people's perception and experience of being in a good situation, satisfaction with the structure, and social interaction. This qualitative study intended to explore nurses’ experience of social well-being. Methods: Qualitative content analysis was used to conduct the study. Through purposive sampling, a total of 18 nurses with various clinical experiences participated in semi-structured interviews. The data were analysed using the five-step, qualitative content analysis introduced by Graneheim and Lundman. Results: The main theme extracted from the data analysis was “thirst for a holistic support” in nurses. It consisted of two subthemes including internal support (family's support, colleague's support, and organizational support and external support (society's support and media's support. Conclusions and discussion: Nurses’ experiences in shaping their social well-being show that nurses need support in order to rebuild their social well-being. It is supported in partnership with the media, the community, health-related organizations, and by nurses and family. This improves job satisfaction, hope, motivation, commitment, and confidence so as to ultimately facilitate improvement of social well-being of nurses.

    Maternal adiposity confers an increased risk of GDM in pregnancy. A low glycemic index (GI) dietary intervention has been found to improve glucose homeostasis and reduce gestational weight gain. Mobile Health (mHealth) Technology-assisted interventions are becoming commonplace as an aid to treating many chronic diseases. The aim of this study is to assess the impact of a 'healthy lifestyle package' with mHealth smart phone technology as support compared with usual care on the incidence of GDM in an overweight and obese pregnant population. We propose a randomized controlled trial of an mHealth assisted healthy lifestyle intervention package versus standard obstetric care in pregnant women with a BMI ≥25kg/m(2)-39.9kg/m(2). Patients are randomized to control or intervention group in a 1:1 ratio. The intervention arm healthy lifestyle package includes a motivational counseling session to encourage behavior change, involving targeted, low GI nutritional advice and daily physical activity prescription delivered before 18weeks gestation, as well as a smart phone app to provide ongoing healthy lifestyle advice and support throughout pregnancy. The primary outcome is the incidence of GDM at 29weeks' gestation and power analysis indicates that 253 women are required in each group to detect a difference. This will be the first clinical trial to evaluate the effectiveness of a smart phone technology-assisted targeted healthy lifestyle intervention, which is grounded in behavior change theories and techniques, to support antenatal management of an overweight and obese pregnant population in preventing GDM.

    Medical writing is a coded language; its purpose is to convey a scientific message. In pathology, specialty involving the study of cell and tissue, quantitative and qualitative production of medical doctoral theses and their thematic focus has not been studied. The aim of this study was to analyze the pathology theses on the level of form, the background and methodology. Descriptive retrospective study of medical doctoral theses in the specialty "Pathology", listed in the catalog of theses of the library of the Faculty of Medicine of Tunis and supported between 2000 and 2010. Each thesis has been subject of a direct reading, systematic and thorough. The study involved 189 pathology theses. The average overall productivity per academic pathologist was 5.5 theses. Gastrointestinal pathology was the most studied theme (24.9%). Tumor pathology was addressed in 74.1% of the theses. The IMRAD structure was respected in 57.7% of theses; by assistant professor than by associate professor and professor (p = 0.005). The summary was structured in 88.3% of theses, comparably with the grade of the thesis director (p = 0.5) and with the grade of PhD student (p = 0.08). The transcript of references did not meet the recommendations of Vancouver in 87.8% of theses and irrespective of the rank of director of thesis (p = 0.2). The pathology theses presented some shortcomings, particularly in the quality of medical writing. To remedy this problem, our faculty should increase efforts to improve the quality of scientific work, in order to have a better view of medical research in Tunisia.

    Objective We conducted a review of the history and performance of developmental neurotoxicity (DNT) testing in support of the finalization and implementation of Organisation of Economic Co-operation and Development (OECD) DNT test guideline 426 (TG 426). Information sources and analysis In this review we summarize extensive scientific efforts that form the foundation for this testing paradigm, including basic neurotoxicology research, interlaboratory collaborative studies, expert workshops, and validation studies, and we address the relevance, applicability, and use of the DNT study in risk assessment. Conclusions The OECD DNT guideline represents the best available science for assessing the potential for DNT in human health risk assessment, and data generated with this protocol are relevant and reliable for the assessment of these end points. The test methods used have been subjected to an extensive history of international validation, peer review, and evaluation, which is contained in the public record. The reproducibility, reliability, and sensitivity of these methods have been demonstrated, using a wide variety of test substances, in accordance with OECD guidance on the validation and international acceptance of new or updated test methods for hazard characterization. Multiple independent, expert scientific peer reviews affirm these conclusions. PMID:19165382

    This work supports the development studies for atmospheric and pressurized fluidized-bed coal combustion. Laboratory and bench-scale (process development) studies are aimed at providing needed information on limestone utilization, control of emission of alkali metal compounds and SO/sub 2/ during combustion, particulate loadings of flue gas, and other aspects of fluidized-bed coal combustion. Characterization of a variety of limestones and dolomites from various parts of the United States for suitability for use in fluidized-bed combustors for SO/sub 2/ emission control is also being done. Reducing the volume of solid wastes to reduce their environmental impact is a major goal. The development of methods for controlling the composition of hot flue gas so that it is a suitable feed gas for gas turbines is another major aim. These studies are designed to supply data and new concepts essential for the timely application of fluidized-bed combustion units to public utility and industrial systems.

    A broadly accepted definition of creativity refers to the production of something both novel and useful within a given social context. Studies of patients with neurological and psychiatric disorders and neuroimaging studies of healthy controls have each drawn attention to frontal and temporal lobe contributions to creativity. Based on previous magnetic resonance (MR) spectroscopy studies demonstrating relationships between cognitive ability and concentrations of N-acetyl-aspartate (NAA), a common neurometabolite, we hypothesized that NAA assessed in gray and white matter (from a supraventricular slab) would relate to laboratory measures of creativity. MR imaging and divergent thinking measures were obtained in a cohort of 56 healthy controls. Independent judges ranked the creative products of each participant, from which a “Composite Creativity Index” (CCI) was created. Different patterns of correlations between NAA and CCI were found in higher verbal ability versus lower verbal ability participants, providing neurobiological support for a critical “threshold” regarding the relationship between intelligence and creativity. To our knowledge, this is the first report assessing the relationship between brain chemistry and creative cognition, as measured with divergent thinking, in a cohort comprised exclusively of normal, healthy participants.

    2012-04-30

    The combination of premature failure of wind turbine gearboxes and the downtime caused by those failures leads to an increase in the cost of electricity produced by the wind. There is a need for guidance to asset managers regarding how to maximize the longevity of their gearboxes in order to help keep the cost of wind energy as low as possible. A low cost of energy supports the US Department of Energy's goal of achieving 20% of the electricity in the United States produced by wind by the year 2030. DNV KEMA has leveraged our unique position in the industry as an independent third party engineering organization to study the problem of gearbox health management and develop guidance to project operators. This report describes the study. The study was conducted in four tasks. In Task 1, data that may be related to gearbox health and are normally available to wind project operators were collected for analysis. Task 2 took a more in-depth look at a small number of gearboxes to gain insight in to relevant failure modes. Task 3 brought together the previous tasks by evaluating the available data in an effort to identify data that could provide early indications of impending gearbox failure. Last, the observations from the work were collected to develop recommendations regarding gearbox health management.

    This paper discusses the effort in evaluating and selecting a light weight impact protection material for the Constellation Space Suit Element (CSSE) Portable Life Support Subsystem (PLSS) conceptual packaging study. A light weight material capable of holding and protecting the components inside the PLSS is required to demonstrate the viability of the flexible PLSS packaging concept. The material needs to distribute, dissipate, and absorb the impact energy of the PLSS falling on the lunar surface. It must also be very robust and function in the extreme lunar thermal vacuum environment for up to one hundred Extravehicular Activity (EVA) missions. This paper documents the performance requirements for selecting a foam protection material, and the methodologies for evaluating commercial off-the-shelf (COTS) foam protection materials. It also presents the materials properties test results and impact drop test results of the various foam materials evaluated in the study. The findings from this study suggest that a foam based flexible protection system is a viable solution for PLSS packaging. However, additional works are needed to optimize COTS foam properties or to develop a composite foam system that will meet all the performance requirements for the CSSE PLSS flexible packaging.

    The aim of this study was to explore the application of the IROMEC (Interactive social RObotic Mediators as Companions) robot to support play for children with severe physical disabilities in rehabilitation and special education. Within a 2-month pilot study, physically disabled children with a developmental age between 2 and 8 years participated in sessions with the robot. A combination of qualitative and quantitative outcome measures was used to collect data on aspects of feasibility, usability, barriers for the child as well as the therapist and an indication of the effects on playfulness and the achievement of therapeutic and educational goals. A total of 11 children participated in this study (four boys, seven girls). Individually Prioritized Problem Assessment scores indicated a positive effect of the IROMEC robot on the achievement of goals for the children. Professionals did observe meaningful application possibilities, but the lacking adaptability, expandability and technical stability of the robot platform make application in daily care practice impossible. The application of a robot like IROMEC for children with severe physical disabilities seems to be positive and worthwhile, but usability and feasibility aspects are crucial for success.

    A broadly accepted definition of creativity refers to the production of something both novel and useful within a given social context. Studies of patients with neurological and psychiatric disorders and neuroimaging studies of healthy controls have each drawn attention to frontal and temporal lobe contributions to creativity. Based on previous magnetic resonance (MR) spectroscopy studies demonstrating relationships between cognitive ability and concentrations of N-acetyl-aspartate (NAA), a common neurometabolite, we hypothesized that NAA assessed in gray and white matter (from a supraventricular slab) would relate to laboratory measures of creativity. MR imaging and divergent thinking measures were obtained in a cohort of 56 healthy controls. Independent judges ranked the creative products of each participant, from which a "Composite Creativity Index" (CCI) was created. Different patterns of correlations between NAA and CCI were found in higher verbal ability versus lower verbal ability participants, providing neurobiological support for a critical "threshold" regarding the relationship between intelligence and creativity. To our knowledge, this is the first report assessing the relationship between brain chemistry and creative cognition, as measured with divergent thinking, in a cohort comprised exclusively of normal, healthy participants.

    2016-06-01

    Water scarcity is a serious global issue, due to the increasing population and developing economy, and membrane technology is an essential way to address this problem. Forward osmosis (FO) is an emerging membrane process, due to its low energy consumption (not considering the draw solute regeneration). A bottleneck to advance this technology is the design of the support layer for FO membranes to minimize the internal concentration polarization. In this dissertation, we focus on the structural study and modification of the support layer for FO membranes. Firstly, we digitally reconstruct different membrane morphologies in 3D and propose a method for predicting performance in ultrafiltration operations. Membranes with analogous morphologies are later used as substrate for FO membranes. Secondly, we experimentally apply substrates with different potentially suitable morphologies as an FO support layer. We investigate their FO performance after generating a selective polyamide layer on the top, by interfacial polymerization. Among the different substrates we include standard asymmetric porous membranes prepared from homopolymers, such as polysulfone. Additionally block copolymer membrane and Anodisc alumina membrane are chosen based on their exceptional structures, with cylindrical pores at least in part. 3D digitally reconstructed porous substrates, analogous to those investigated for ultrafiltration, are then used to model the performance in FO operation. Finally, we analyze the effect of intermediate layers between the porous substrate and the interfacial polymerized layer. We investigate two materials including chitosan and hydrogel. The main results are the following. Pore-scale modeling for digital membrane generation effectively predicts the velocity profile in different layers of the membrane and the performance in UF experiments. Flow simulations confirm the advantage of finger-like substrates over sponge-like ones, when high water permeance is sought

    Full Text Available This paper describes discipline-specific transition support utilised to follow-up the Post-Entry Language Assessment (PELA recently introduced at Edith Cowan University as one strategy to address declining rates of English language proficiency.  Transition support was embedded within a first year core unit and emphasis was placed on assisting students to develop spoken and written communicative competencies by scaffolding assessment tasks and providing other academic supports that used contextualised examples. While general satisfaction with the academic support offered during the course was high, the program achieved limited success in encouraging at-risk students to seek support. Further investigation into methods of encouraging student participation is required, along with research into strategies for extending effective academic socialisation support into the online learning environment.

    Agricultural industrialization is an innovative operation mode and effective drive for transformation of traditional agriculture to modern agriculture. Benign development of agricultural industrialization depends on financial support. With increase of the function of financial support for agricultural industrialization development,academic circles have made deeper and deeper researches on agricultural industrialization. These researches mainly touch upon four aspects:( i) definition of concept of financial support for agricultural industrialization;( ii)functions of financial support for agricultural industrialization;( iii) existing problems in financial support for agricultural industrialization and problem causes;( iv) specific recommendations of promotion of financial support for agricultural industrialization development. Although existing researches are already extensive and some common understandings have been reached,there are still some research gaps and weak points,and it needs further researches.

    During the centuries, the seaside has represented a crucial pole for future human development and civilization. The use of the sea for transport and trade and the overwhelming availability of food derived from coastal waters have encouraged and strengthened the growth of urban settlements. In the same time, the human pressure menaces to destroy coastal habitats and consequently their carrying capacity that allows for many essential functions. Low-impact activities are often replaced, on the surface, by new intensive ones that are attractive in the short term, but that in the long term undermine by reducing the resilience of the coast. It is clear that, in a perspective of sustainable development, economically efficient and socially equitable use of coastal areas need to be supported inside strategies to correct these weaknesses. The definition of such strategies and their implementation in the Strategic Environmental Assessment (SEA) is an essential tool for supporting decisions and of monitoring. The issues of monitoring, more in particular, have been the subject of study and modelling by the use of Dynamic Spatial Data Analysis (DSDA), in the case of the SEA of the Coastal Plan of the Italian Apulia Region, as an information instrument for regulating the anthropogenic changes; a possibility to implement the analysis of environmental sensitivity and propensity to Coastal erosion has been explored, in order to control the level of human pressure on land. The monitoring system should provide an automatic "alert" when the dimension and the velocity of the change of land use overpass some threshold of environmental pressure.

    The Minority University Consortium for Earth and Space Sciences (MUCESS) supports yearly atmospheric science workshops at their respective institutions. The NSF funded program has enabled Universities and colleges that are part of MUCESS, which include Medgar Evers College, City University of NY, University of Houston-Downtown and South Carolina State University, to develop and support atmospheric studies. The goal of the annual workshops is to instruct the students on the basics of atmospheric science and provide them with hands-on experience for preparing and calibrating the instruments for measuring atmospheric parameters. The instruments are subsequently attached to weather balloons. The data is obtained with an ENSCI ECC ozonesonde, which measures ozone concentrations to parts per billion, and an iMET radiosonde, which records temperature, pressure, relative humidity, and GPS altitude and position. In March 2010, Medgar Evers hosted the workshop in Paradox, NY. Students and faculty from the three institutions attended the 3 day workshop. Subsequent to the annual workshop students from the University of Houston-Downtown (UHD) launched a series of four Sunday launches during the summer from the campus. The data from both the workshop and UHD launches was subsequently analyzed to compare ozone profiles within the troposphere and stratosphere. Comparing rural (Paradox, NY) and urban ozone profiles (Houston, Tx) provides an invaluable experience. An excellent example is the March Paradox temperature profiles as the data indicates a mid-tropospheric temperature inversion. Coincident with this inversion, there is a significant rise in ozone concentrations, the source of which is likely of non-local provenance. In contrast, the Houston summer data indicates a different story as ground level ozone is produced by industrial and transportation-related ozone sources levels which vary. Weekend ground level ozone levels on Sunday are usually relatively low because of

    2013-12-01

    New technologies enable new forms of patient participation in health care. The article discusses whether communication in online patient support groups is a source of individual as well as collective empowerment or to be understood within the tradition of compliance. The discussion is based on a qualitative analysis of patient communication in two online groups on the Danish portal sundhed.dk, one for lung patients and one for women with fertility problems. The object of study is the total sum of postings during a specific period of time - a total of 4301 posts are included. The textmaterial was analyzed according to the textual paradigm of Paul Ricoeur, and the three steps of critical interpretation. Thus, the analysis moves from describing communicative characteristics of the site to a thorough semantic analysis of its narrative structure of construing meaning, interaction and collective identity, and finally as a source of collective action. The meta-narratives of the two groups confirm online patient support groups for individual empowerment, for collective group identity, but not for collective empowerment. The collective identities of patienthood on the two sites are created by the users (patients) through specific styles of communication and interaction, referred to as 'multi-logical narratives'. In spite of the potential of online communities of opening up health care to the critical voice of the public, the analysis points to a synthesis of the otherwise opposite positions of empowerment and compliance in patient care. On a collective level, the site is empowering the individual users to comply with 'doctor's recommendations' as a group. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Ni catalysts supported on {alpha}-Al{sub 2}O{sub 3}, ZrO{sub 2} and {alpha}-Al{sub 2}O{sub 3}-ZrO{sub 2} were studied in the synthesis gas reactions (partial oxidation, dry reforming and mixed reforming). The Ni/{alpha}-Al{sub 2}O{sub 3}-ZrO{sub 2} catalyst showed a very good performance in relation to the initial activity and selectivity, comparable to that of the Ni/{alpha}-Al{sub 2}O{sub 3} catalyst. Concerning the deactivation, the modification of the {alpha}-Al{sub 2}O{sub 3} supported with ZrO{sub 2} leads to a higher stability, due to the strong inhibition of the carbon formation during the reaction. These results suggest that ZrO{sub 2} promotes the gasification of adsorbed intermediates, which are precursors of carbon formation. Temperature programmed oxidation, transmission electron microscopy and Raman spectroscopy experiments showed that on Ni/{alpha}-Al{sub 2}O{sub 3} catalyst high amounts of graphitic carbon (whisker-like) are deposited during CO{sub 2} reforming reaction, while on Ni/{alpha}-Al{sub 2}O{sub 3}-ZrO{sub 2} lesser amounts of deposited carbon were observed (about one order lower); a fraction of this carbon is of the same nature as that observed on Ni/{alpha}-Al{sub 2}O{sub 3} catalyst, while the other fraction is composed of carbon nanotubes, both of single wall and multi wall.

    Full Text Available During the construction of newly built tunnel (NBT adjacent to the existing service tunnel (EST, stability of the EST with small interval is affected by vibration waves which are caused by blasting load. The support structures of the EST will be cracked and damaged, while the unreasonable blast-excavation methods are adopted. Presently, the studies on behavior of support structure in the EST under blasting load are not totally clear, especially for the bolts system. Besides, the responses of support structure on blasting load are lacking comprehensive research. In this paper, New Zuofang tunnel is taken as a study case to study the influence of step blast-excavation in NBT on support structures of the EST through field experiment and numerical simulation. Some data, such as blasting vibration velocity (BVV and frequency of support structures, are obtained through field measurement. Based on these data, the formula of BVVs is obtained. Research on stability of tunnel support structures affected by step blast-excavation is conducted using numerical simulation method. The dynamic-plastic constitutive model is adopted in the software ABAQUS to assess safety of support structures. The range and degree of damage for the support structures are obtained. In addition, change laws of axial force and stress with time for the bolts are analyzed.

    Full Text Available Community support and participation among persons with disabilities. A study in three European countriesThis article describes a European project which was aimed at improving the situation of persons with psychiatric or learning disabilities with regard to social participation and citizenship. The project took place in three countries (Estonia, Hungary and the Netherlands and four cities (Tallinn, Budapest, Amersfoort and Maastricht. The project included research and actions at the policy level, the organizational level and the practice level. At the policy level, the framework of the United Nations Convention on the Rights of Persons with Disabilities (United Nations, 2006 and the European Disability Strategy (European Commission, 2010 were used to look at national and local policies, at the reality of the lives of those with disabilities and at the support that professional services offer with regard to participation and inclusion. The project generated a number of insights, recommendations and methods by which to improve the quality of service and increase the number of opportunities for community engagement. In this article, we present some of the lessons learned from the meta-analysis. Although the circumstances in each country are quite different with regard to policy, culture and service systems, it is remarkable that people with disabilities face many of the same problems.The study shows that in all three countries, access to services could be improved. Barriers include bureaucratic procedures and a lack of services. The research identified that in every country and city there are considerable barriers regarding equal participation in the field of housing, work and leisure activities. In addition to financial barriers, there are the barriers of stigma and self-stigmatization. Marginalization keeps people in an unequal position and hinders their recovery and participation. In all countries, professionals need to develop a stronger focus

  4. Pulsatile flow in the aorta of the LVAD supported heart studied using particle image velocimetry

    Moyedi, Zahra

    Currently many patients die because of the end-stage heart failure, mainly due to the reduced number of donor heart transplant organs. Studies show that a permanent left ventricular assist device (LVAD), a battery driven pump which is surgically implanted, increased the survival rate of patients with end-stage heart failure and improved considerably their quality of life. The inlet conduit of the LVAD is attached to the left ventricle and the outflow conduit anastomosed to the ascending aorta. The purpose of LVAD support is to help a weakened heart to pump blood to the rest of the body. However LVAD can cause some alterations of the natural blood flow. When your blood comes in contact with something that isn't a natural part of your body blood clots can occur and disrupt blood flow. Aortic valve integrity is vital for optimal support of left ventricular assist LVAD. Due to the existence of high continuous transvalvular pressure on the aortic valve, the opening frequency of the valve is reduced. To prevent the development of aortic insufficiency, aortic valve closure during LVAD implantation has been performed. However, the closed aortic valve reduces wash out of the aortic root, which causes blood stagnation and potential thrombus formation. So for this reason, there is a need to minimize the risks of occurring blood clot, by having more knowledge about the flow structure in the aorta during LVAD use. The current study focuses on measuring the flow field in the aorta of the LVAD assisted heart with two different types of aortic valve (Flat and Finned) using the SDSU cardiac simulator. The pulsatile pump that mimics the natural pulsing action of the heart also added to the system. The flow field is visualized using Particle Image Velocimetry (PIV). Furthermore, The fluid mechanics of aorta has been studied when LVAD conduit attached to two different locations (proximal and distal to the aortic valve) with pump speeds of 8,000 to 10,000 revolutions per minute (RPM

    Space-based observations offer unique capabilities for studying spatial and temporal dynamics of the upper ocean inorganic carbon cycle and, in turn, supporting research tied to ocean acidification (OA). Satellite sensors measuring sea surface temperature, color, salinity, wind, waves, currents, and sea level enable a fuller understanding of a range of physical, chemical, and biological phenomena that drive regional OA dynamics as well as the potentially varied impacts of carbon cycle change on a broad range of ecosystems. Here, we update and expand on previous work that addresses the benefits of space-based assets for OA and carbonate system studies. Carbonate chemistry and the key processes controlling surface ocean OA variability are reviewed. Synthesis of present satellite data streams and their utility in this arena are discussed, as are opportunities on the horizon for using new satellite sensors with increased spectral, temporal, and/or spatial resolution. We outline applications that include the ability to track the biochemically dynamic nature of water masses, to map coral reefs at higher resolution, to discern functional phytoplankton groups and their relationships to acid perturbations, and to track processes that contribute to acid variation near the land-ocean interface.

    This paper discusses the phase I effort in evaluating and selecting a light weight impact protection material for the Constellation Space Suit Element (CSSE) Portable Life Support System (PLSS) conceptual packaging study. A light weight material capable of holding and protecting the components inside the PLSS is required to demonstrate the viability of the flexible PLSS packaging concept. The material needs to distribute, dissipate, and absorb the impact energy of the PLSS falling on the lunar surface. It must also be robust to consistently perform over several Extravehicular Activity (EVA) missions in the extreme lunar thermal vacuum environment. This paper documents the performance requirements for selecting a foam protection material, and the methodologies for evaluating some commercial off-the-shelf (COTS) foam material candidates. It also presents the mechanical properties and impact drop tests results of the foam material candidates. The results of this study suggest that a foam based flexible protection system is a viable solution for PLSS packaging. However, additional works are needed to optimize COTS foam or to develop a composite foam system that will meet all the performance requirements for the CSSE PLSS flexible packaging.

    It is desired to detect stenosis at an early stage to use hemodailysis shunt for longer time. Stethoscope auscultation of vascular murmurs is useful noninvasive diagnostic approach, but an experienced expert operator is necessary. Some experts often say that the high-pitch murmurs exist if the shunt becomes stenosed, and some studies report that there are some features detected at high frequency by time-frequency analysis. However, some of the murmurs are difficult to detect, and the final judgment is difficult. This study proposes a new diagnosis support system to screen stenosis by using vascular murmurs. The system is performed using artificial neural networks (ANN) with the analyzed frequency data by maximum entropy method (MEM). The author recorded vascular murmurs both before percutaneous transluminal angioplasty (PTA) and after. Examining the MEM spectral characteristics of the high-pitch stenosis murmurs, three features could be classified, which covered 85 percent of stenosis vascular murmurs. The features were learnt by the ANN, and judged. As a result, a percentage of judging the classified stenosis murmurs was 100%, and that of normal was 86%.

    The electroencephalogram (EEG) signal captures the electrical activity of the brain and is an important source of information for studying neurological disorders. The proper analysis of this biological signal plays an important role in the domain of brain-computer interface, which aims at the construction of communication channels between human brain and computers. In this paper, we investigate the application of least squares support vector machines (LS-SVM) to the task of epilepsy diagnosis through automatic EEG signal classification. More specifically, we present a sensitivity analysis study by means of which the performance levels exhibited by standard and least squares SVM classifiers are contrasted, taking into account the setting of the kernel function and of its parameter value. Results of experiments conducted over different types of features extracted from a benchmark EEG signal dataset evidence that the sensitivity profiles of the kernel machines are qualitatively similar, both showing notable performance in terms of accuracy and generalization. In addition, the performance accomplished by optimally configured LS-SVM models is also quantitatively contrasted with that obtained by related approaches for the same dataset.

    The membrane properties of phospholipid mixtures supported on silica were studied by means of a quartz crystal microbalance with dissipation monitoring (QCM-D) technique, in situ soft-contact atomic force microscopy (AFM), and friction force microscopy (FFM). The phospholipids used in this study were di-stearoylphosphatidylcholine (DSPC) and dilauroylphosphatidylcholine (DLPC). The phospholipid films were prepared by a vesicle-fusion method, in which DSPC/DLPC mixed liposomes dispersed in an aqueous medium are adsorbed on silica and their structure is transformed into a bilayer on the substrate. The changes in QCM-D (frequency and dissipation) and friction responses of DSPC single systems (gel state at 25°C) are relatively large compared with those of DLPC single systems (liquid-crystalline state at 25°C) and those of mixed DSPC/DLPC systems. This suggests that (i) the gel-state DSPC liposomes are somewhat flattened on the silica, by keeping their solid-like molecular rigidity, whereas (ii) both the liquid-crystalline DLPC and mixed liposomes experience instantaneous structural transformation at the silica/water interface and form a normally flattened bilayer on the substrate. The friction force response is dependent on the phase state of the phospholipids, and the liquid-crystalline DLPC has a more significant impact on the overall membrane properties (i.e., the degree of swelling and the friction response on the surface) than does the gel-state DSPC.

    Adherence to pharmacological or non-pharmacological treatment of diabetes type 2 is fundamental in order to delay the onset of complications. To measure the effect of nursing educational support on compliance with treatment in patients with type 2 diabetes attending Regional Hospital Universitario of Colima, Mexico. An experimental, randomized study including outpatients with type 2 diabetes attending a Regional Hospital who agreed in writing to participate in the study. Nursing educational intervention sessions of three hours on two days a week for three months were provided. Adherence to treatment was assessed before and after intervention using the Scale for treatment adherence in type 2 diabetes (EATDM-III(©)). We performed two-proportion Z and p; Risk Ratio and confidence interval 95% and attributable fraction exposed. e experimental group had 32 members, the same as the control. After the intervention it was found that 16 members (50%) in the experimental group showed treatment adherence, unlike the control group where no one showed adherence to treatment, obtaining an independent two-proportion Z=4.62, P=.0000, Risk Ratio=65; Confidence Interval 95%=3.67 to 1152.38; exposed attributable fraction=98.46%. The intervention was effective for the adherence of treatment. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Although the important role of social support in mental health is acknowledged, no prospective study has yet examined the relation of social support to suicide. Here, we investigated the association between social support and suicide in a cohort of Japanese men and women. A total of 26,672 men and 29,865 women aged 40-69 years enrolled in the Japan Public Health Center-based prospective study in 1993-1994 completed a self-administered questionnaire which included four items of social support, and were followed for death through December 2005. Hazard ratios (HRs) and 95% confidence intervals (95% CI) of suicidal death by social support index were estimated using a Cox proportional hazards regression model. A total of 180 suicidal deaths were recorded during an average of 12 years' follow-up. Men and women with the highest level of social support had a significantly decreased risk of suicide, with HRs (95% CI) for the highest versus lowest social support group of 0.56 (0.33-0.94) and 0.38 (0.16-0.89) in men and women, respectively. Esteem support and having four or more friends were associated with a lower risk of suicide in women [0.32 (0.13-0.77)] and in both sexes [men: 0.56 (0.36-0.88); women: 0.65 (0.32-1.30)], respectively, whereas confident support was not. These findings suggest that social support may be important for suicide prevention. Avoiding social isolation may decrease the incidence of suicide in men and women, and esteem support can provide additional benefit for women.

    SMS text messaging shows promise for delivering smoking cessation support. However, little is known about smokers' feelings towards receiving behavioural advice and support on their mobile phones. This article explores the attitudes of women with experience of prenatal smoking towards receiving pregnancy-related smoking cessation support by text message. Data collected by semi-structured interviews and focus group from women who received either tailored smoking cessation texts or no text support (N = 33) were analysed using thematic analysis. Three themes emerged: convenience, high expectations and perceived source. Texting was regarded as a highly convenient mode of support delivery leading to high levels of attention to messages, although high convenience sometimes resulted in the value of a text being short-lived. Many who did not receive texts had high expectations for text support to intervene with routine smoking behaviour in real time. Those who received texts (with no real-time intervention element), however, felt they were helpful and supportive. Participants discussed how factors relating to perceived source, including personalization, personal relevance and salience of text automatization, could affect message attention and impact. Our findings provide insight into how maximizing personalization and personal relevance can increase the value of text message support and reduce the risk of disengagement.

    Despite the increasing popularity of mechanized coal mining, there are no convenient and accurate means available to measure the loads of powered supports. The measurement of such loads is important for monitoring mine pressure and ensuring production safety. The load-carrying features of a powered support were used to develop a method for load measurement using the magnetoelastic principle. A cross bridge-type magnetoelastic stress sensor was designed for the support structures to measure the different parts of the supports. Tests on single-body hydraulic cylinders and simulated linkages showed that an approximately linear relationship between the values of the sensor output signal and the loads borne by the hydraulic cylinders or linkages. The results were used to analyze the load-carrying measurements of powered supports with the cross bridge-type magnetoelastic stress sensor.

    Studies from North America have concluded that supported employment using the Individual Placement and Support (IPS) model is effective in helping individuals with severe and persistent mental illness gain competitive employment. The aim of this study was to investigate the effectiveness and cost-effectiveness of IPS in England in patients followed up for 2 years. Patients with severe mental illness were randomised to IPS or local vocational services (treatment as usual). Service use and costs were measured. Two hundred-nineteen participants were randomised, and 86% re-assessed 2 years later. In the multivariate analysis, relatively low rates of competitive employment were found in both the intervention group and the treatment as usual group, although significantly more patients obtained competitive employment in the treatment arm (22% vs. 11%, p=0.041). There were no significant differences in costs. The employment rate among participants receiving IPS was lower than in previously published reports, and the number needed to treat to obtain the benefit of IPS was relatively high. This may reflect difficulties in the implementation of IPS where it is not structurally integrated within mental health teams, as well as economic disincentives which lead to lower levels of motivation for patients and mental health professionals.

    Full Text Available Basically this study intended to find out essential basic values which support social harmony in conflict-prone areas, with a profound study at primary schools in Sambas regency, west Kalimantan. As revealed by a number of data sources, west Kalimantan is one of the areas which is prone to conflict. This is evidenced by the happening of several ethnic conflicts including in Sambas regency so that it is an important policy of the regional government to find a solution in order to prevent similar conflicts from happening again in the future.The profound study at primary schools is deemed highly essential since social harmony values should be instilled among the students at an early age. In addition to that, teachers are knowledgeable about the foundation which creates an attitute of harmony among their students.The method used in this research is a qualitative one, with primary school teachers as the subject of the research. They represent three characteristic areas, namely: the urban area, the suburban area and the remote area of Sambas regency. Primary data collection was carried out through interview and focus group discussion (FGD, with the interactive model proposed by Miles & Huberman as technique of qualitative data analysis. The findings obtained from data collection and analysis revealed that social harmony has an important and profound meaning for society in Sambas regency. Basically there are three pillars of essential basic values which serve as the framework of social harmony, namely: (a the basic values of mutual respect, (b the basic values of tolerance and togetherness, and (c the basic values of freedom and responsibility. Internalization of these basic values happen intensively especially in families through custom formation at households and society in Sambas regency. Meanwhile at schools these basic values are developed and reinforced through more formal custom formation by the teachers and school regulations.

    Full Text Available Abstract Background First responders are recommended as a supplement to the Emergency Medical Services (EMS in order to achieve early defibrillation. Practical and organisational aspects are essential when trying to implement new parts in the "Chain of Survival"; areas to address include minimizing dispatch time, ensuring efficient and quick communication, and choosing areas with appropriate driving distances. The aim of this study was to implement a system using Basic Life Support (BLS responders equipped with an automatic external defibrillator in an area with relatively short emergency medical services' response times. Success criteria for implementation was defined as arrival of the BLS responders before the EMS, attachment (and use of the AED, and successful defibrillation. Methods This was a prospective observational study from September 1, 2005 to December 31, 2007 (28 months in the city of Aarhus, Denmark. The BLS responder system was implemented in an area up to three kilometres (driving distance from the central fire station, encompassing approximately 81,500 inhabitants. The team trained on each shift and response times were reduced by choice of area and by sending the alarm directly to the fire brigade dispatcher. Results The BLS responders had 1076 patient contacts. The median response time was 3.5 minutes (25th percentile 2.75, 75th percentile 4.25. The BLS responders arrived before EMS in 789 of the 1076 patient contacts (73%. Cardiac arrest was diagnosed in 53 cases, the AED was attached in 29 cases, and a shockable rhythm was detected in nine cases. Eight were defibrillated using an AED. Seven of the eight obtained return of spontaneous circulation (ROSC. Six of the seven obtaining ROSC survived more than 30 days. Conclusion In this study, the implementation of BLS responders may have resulted in successful resuscitations.

    One of suspect environmental endocrine disruptors that affect mouse male reproduction by altering the morphology of Sertoli cells and spermatogenic cells is phthalate. The effects of mono(2-ethylhexyl)phthalate (MEHP), one of metabolites of di(2-ethylhexyl)phthalate , on immature mouse testes in vivo were examined. We have recently shown that MEHP induced Sertoli cells necrosis and spermatogenic cells apoptosis in mice by TUNEL method, F-actin staining, and ultrastructural study, but there is no data for biochemical changing of testes due to those methods could not explore. To verify in detail of it, we conducted Raman spectroscopy study with 785 nm wavelength laser line, 50mW of laser power and 3 minutes of exposure time to analysis the MEHP-treated testicular tissue, which has been fixatived by 4% paraformaldehyde (PFA). Five weeks old (5 w.o) male mice were used in this experiment. As the results, the alterations were observed by Raman spectroscopy that there are significantly differences of DNA, actin filament, type IV collagen and amide I between control group (0 μM MEHP) and treatment group (100 μM MEHP). These results significantly support histology staining observation (such as the apoptotic spermatogenic cells which is associated with DNA fragmentation and F-actin disruption) and ultrastructural observation (such as mitochondria rupture and disintegration of nucleus membrane). Raman spectroscopy can be used for 4% PFA-fixatived tissue observation. However, we recommend that Raman spectroscopy may be able to be expanded as an armamentarium not just for the clarification of histology staining and ultrastructural study, but furthermore, it may be as a non-invasion assessment for screening animal tissue toxicity of chemical in future.

    Observational studies have found that relative to healthy controls, patients with Parkinson's disease have lower circulating concentrations of 25-hydroxyvitamin D, a clinical biomarker of vitamin D status. However, the causality of this association is uncertain. We undertook a Mendelian randomization study to investigate whether genetically decreased 25-hydroxyvitamin D concentrations are associated with PD to minimize confounding and prevent bias because of reverse causation. As instrumental variables for the Mendelian randomization analysis, we used 4 single-nucleotide polymorphisms that affect 25-hydroxyvitamin D concentrations (rs2282679 in GC, rs12785878 near DHCR7, rs10741657 near CYP2R1, and rs6013897 near CYP24A1). Summary effect size estimates of the 4 single-nucleotide polymorphisms on PD were obtained from the International Parkinson's Disease Genomics Consortium (including 5333 PD cases and 12,019 controls). The estimates of the 4 single-nucleotide polymorphisms were combined using an inverse-variance weighted meta-analysis. Of the 4 single-nucleotide polymorphisms associated with 25-hydroxyvitamin D concentrations, one (rs6013897 in CYP24A1) was associated with PD (odds ratio per 25-hydroxyvitamin D-decreasing allele, 1.09; 95% confidence interval, 1.02-1.16; P = 0.008), whereas no association was observed with the other 3 single-nucleotide polymorphisms (P > 0.23). The odds ratio of PD per genetically predicted 10% lower 25-hydroxyvitamin D concentration, based on the 4 single-nucleotide polymorphisms, was 0.98 (95% confidence interval, 0.93-1.04; P = 0.56). This Mendelian randomization study provides no clear support that lowered 25-hydroxyvitamin D concentration is causally associated with risk of PD. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

In the present study, we investigated relationships between social support, gratitude, and sense of coherence, focusing on the construct of and source of social support among young women. Methods: The study was conducted in 2014 in Japan. Participants comprised 208 female university students (aged 19.9 ± 1.1 years, who completed a self-administered anonymous questionnaire regarding perceived social support, gratitude, and sense of coherence. Results: Emotional and instrumental social support from acquaintances were found to be lower than those from family and friends. Gratitude was positively correlated with all forms of social support except instrumental social support from acquaintances. However, sense of coherence was positively correlated with both emotional and instrumental social support from family and only emotional social support from acquaintances. Multiple regression analysis showed that ­emotional support from family and emotional support from acquaintances were positively associated

In our experiment, supported noble metal catalysts exhibited better performance than the other supported transition metal catalysts. The catalyst performances were significantly influenced by the d-electron configuration of the active metal components and the dispersion of active metal components on the support. A catalyst with a moderate number of unpaired electrons in the d-orbital of the active metal support without obvious acidity or redox activity (e.g. MgO) was suitable for POM performance. The Rh/SiO2 catalyst was the best in the POM reaction, among those investigated. Reaction conditions apparently also affected the POM performance of the catalyst. The conversion of methane and the selectivity for CO increased with the reaction temperature, and a high CH4/O2 ratio was not beneficial for POM performance.

    Identify the breastfeeding knowledge, the attitudes towards sexuality and breastfeeding and the disposition towards supporting breastfeeding in future fathers were the aims of this study. A non-probabilistic sample (n = 100) of future Puerto Rican male parents was used in this study. A self-administered questionnaire was used consisting of four sections. Descriptive statistics were used for data analysis and t-test to the inferential analysis. 88.8% of the participants presented a low level of knowledge. However, 81.6% had a positive attitude toward sexuality and breastfeeding. Also, 92.0% of the participants indicated much/enough willingness to support their partners in exclusively breastfeeding. Disposition to support the breastfeeding was associated with knowledge towards breastfeeding (p = 0.04) and attitudes toward sexuality and breastfeeding (p = 0.00). The knowledge and the attitudes, in this study, are strongly related with the disposition of the father to supporting the breastfeeding in the future.

    Full Text Available OBJECTIVE: Health care professionals access various information sources to quickly answer questions that arise in clinical practice. The features that favorably influence the selection and use of knowledge resources remain unclear. We sought to better understand how clinicians select among the various knowledge resources available to them, and from this to derive a model for an effective knowledge resource. METHODS: We conducted 11 focus groups at an academic medical center and outlying community sites. We included a purposive sample of 50 primary care and subspecialist internal medicine and family medicine physicians. We transcribed focus group discussions and analyzed these using a constant comparative approach to inductively identify features that influence the selection of knowledge resources. RESULTS: We identified nine features that influence users' selection of knowledge resources, namely efficiency (with sub-features of comprehensiveness, searchability, and brevity, integration with clinical workflow, credibility, user familiarity, capacity to identify a human expert, reflection of local care processes, optimization for the clinical question (e.g., diagnosis, treatment options, drug side effect, currency, and ability to support patient education. No single existing resource exemplifies all of these features. CONCLUSION: The influential features identified in this study will inform the development of knowledge resources, and could serve as a framework for future research in this field.

  5. Modeling the Financial Distress of Microenterprise StartUps Using Support Vector Machines: A Case Study

    Full Text Available Despite the leading role that micro-entrepreneurship plays in economic development, and the high failure rate of microenterprise start-ups in their early years, very few studies have designed financial distress models to detect the financial problems of micro-entrepreneurs. Moreover, due to a lack of research, nothing is known about whether non-financial information and nonparametric statistical techniques improve the predictive capacity of these models. Therefore, this paper provides an innovative financial distress model specifically designed for microenterprise startups via support vector machines (SVMs that employs financial, non-financial, and macroeconomic variables. Based on a sample of almost 5,500 micro- entrepreneurs from a Peruvian Microfinance Institution (MFI, our findings show that the introduction of non-financial information related to the zone in which the entrepreneurs live and situate their business, the duration of the MFI-entrepreneur relationship, the number of loans granted by the MFI in the last year, the loan destination, and the opinion of experts on the probability that microenterprise start-ups may experience financial problems, significantly increases the accuracy performance of our financial distress model. Furthermore, the results reveal that the models that use SVMs outperform those which employ traditional logistic regression (LR analysis.

    Full Text Available Abstract Background The proportion of Ugandan children who are fully vaccinated has varied over the years. Understanding vaccination behaviour is important for the success of the immunisation programme. This study examined influences on immunisation behaviour using the attitude-social influence-self efficacy model. Methods We conducted nine focus group discussions (FGDs with mothers and fathers. Eight key informant interviews (KIIs were held with those in charge of community mobilisation for immunisation, fathers and mothers. Data was analysed using content analysis. Results Influences on the mother's immunisation behaviour ranged from the non-supportive role of male partners sometimes resulting into intimate partner violence, lack of presentable clothing which made mothers vulnerable to bullying, inconvenient schedules and time constraints, to suspicion against immunisation such as vaccines cause physical disability and/or death. Conclusions Immunisation programmes should position themselves to address social contexts. A community programme that empowers women economically and helps men recognise the role of women in decision making for child health is needed. Increasing male involvement and knowledge of immunisation concepts among caretakers could improve immunisation.

    This work supports the development of atmospheric and pressurized fluidized-bed coal combustion. Laboratory and process development studies are aimed at providing needed information on limestone utilization, control of emission of alkali metal compounds and SO/sub 2/ during combustion, particulate loadings of flue gas, and other aspects of fluidized-bed coal combustion. This report presents information on: the SO/sub 2/ reactivities and thus the limestone requirements of sixty different limestones, the morphology of a few selected stones, the effect of water in the gaseous mixture on the SO/sub 2/ reactivities of three limestones, the effect of combustion conditions on the attrition of limestones, the effect of temperature on SO/sub 2/ retention by limestone in a carbon burnup cell, the effect of CaCl/sub 2/ and MgCl/sub 2/ additives on the SO/sub 2/ capacity of limestones, the use of diatomaceous earth and activated bauxite to remove alkali metal compounds from simulated combustion gas mixtures, selection of laser spectroscopy methods to be evaluated for the measurement of gaseous alkali metal species in hot flue gases, the application of acoustic dust conditioning to flue gas cleaning, and the conceptual design of a granular-bed filter for cleaning of flue gas in a 200-MWe fluidized-bed combustion facility.

    2012-01-01

    Full Text Available This study carries out a parametrical analysis of the seismic response to asynchronous earthquake ground motion of a long multispan rc bridge, the Fener bridge, located on a high seismicity area in the north-east of Italy. A parametrical analysis has been performed investigating the influence of the seismic input correlation level on the structural response: a series of nonlinear time history analyses have been executed, in which the variation of the frequency content in the accelerograms at the pier bases has been described by considering the power spectral density function (PSD and the coherency function (CF. In order to include the effects due to the main nonlinear behaviours of the bridge components, a 3D finite element model has been developed, in which the pounding of decks at cap-beams, the friction of beams at bearings, and the hysteretic behaviour of piers have been accounted for. The sensitivity analysis has shown that the asynchronism of ground motion greatly influences pounding forces and deck-pier differential displacements, and these effects have to be accurately taken into account for the design and the vulnerability assessment of long multispan simply supported bridges.

    To support fingerprint expert opinion, this research proposes an approach that combines subjective human analysis (as currently applied by fingerprint practitioners) with a statistical test of the result. This approach relies on the hypothesis that there are limits to the distortion caused by skin stretch. Such limits can be modelled by applying a multivariate normal probability density function to the distances and angle formed by a marked ridge characteristic and the two closest neighbouring minutiae. This study presents a model tested on 5 donors in total. The "expected range" of distortion in a within-source comparison using 10 minutiae was determined and compared to between-source comparisons. The expected range of log probability densities for within-source comparisons marked with 10 minutiae was determined to be from -33.4 to -60.0, with all between-source data falling outside this range, between -83 and -305. These results suggest that the proposed generated metric could be a powerful tool for the assessment of fingerprint expert opinion in operational casework.

    The infrared drying of an aqueous polymer emulsion spread on a thin composite flat film is experimentally studied. The composite film is composed of polyamide fibers supported by a poly(vinyl fluoride) film. The aqueous polymer is an Ethylene Vinyl Acetate emulsion playing the role of adhesive. It is spread over the film with a low thickness, about one hundred micrometers. The aim of this work is to understand the effects of the presence of fibers on the drying of this thin-layer product. With this in mind, a specific laboratory set up composed of a near infrared heater is used in order to get the drying kinetics. First, incident heat fluxes received at the product surface and transmittances of materials (semi-transparent medium) are measured with an ad-hoc heat flux sensor. Then, many experiments are performed with and without fibers. For linking the final moisture content to the fibers thermal and hydric behavior, a microscopic analysis of the dried samples is investigated. This analysis is performed for two thicknesses of polymer corresponding to two covering rates of fibers.

    Full Text Available Abstract Background Although social support has been observed to exert a beneficial influence on leisure-time physical activity (LTPA, multidimensional approaches examining social support and prospective evidence of its importance are scarce. The purpose of this study was to investigate how four dimensions of social support affect LTPA engagement, maintenance, type, and time spent by adults during a two-year follow-up. Methods This paper reports on a longitudinal study of 3,253 non-faculty public employees at a university in Rio de Janeiro (the Pró-Saúde study. LTPA was evaluated using a dichotomous question with a two-week reference period, and further questions concerning LTPA type (individual or group and time spent on the activity. Social support was measured by the Medical Outcomes Study Social Support Scale (MOS-SSS. To assess the association between social support and LTPA, two different statistical models were used: binary and multinomial logistic regression models for dichotomous and polytomous outcomes, respectively. Models were adjusted separately for those who began LTPA in the middle of the follow up (engagement group and for those who had maintained LTPA since the beginning of the follow up (maintenance group. Results After adjusting for confounders, statistically significant associations (p Conclusions All dimensions of social support influenced LTPA type or the time spent on the activity. However, our findings suggest that social support is more important in engagement than in maintenance. This finding is important, because it suggests that maintenance of LTPA must be associated with other factors beyond the individual's level of social support, such as a suitable environment and social/health policies directed towards the practice of LTPA.

    Full Text Available Social anxiety is characterized by an excessive fear of being embarrassed in social interactions or social performance situations. Emotional support can help to decrease or diminish social distress. Such support may play an important role at different points of social interaction. However, it is unclear how the beneficial effects of social support are represented in the brains of socially anxious individuals. To explore this, we used the same paradigm previously used to examine the effects of emotional support on social pain caused by exclusion. Undergraduates (n = 46 showing a wide range of social anxiety scores underwent functional magnetic resonance imaging (fMRI while participating in a Cyberball game. Participants were initially included and later excluded from the game. In the latter half of the session in which participants were excluded, they were provided with supportive messages. In line with our previous work, we found that social exclusion led to increased anterior cingulate cortex (ACC activity, whereas emotional support led to increased left dorsolateral prefrontal cortex (DLPFC activity. Despite validation of the paradigm, social anxiety was not associated with increased ACC activity during social exclusion, or during perceived emotional support. Instead, fear of negative evaluation as assessed by the Brief Fear of Negative Evaluation (BFNE scale showed positive associations with left DLPFC activation while receiving emotional support, compared to while being socially excluded. The more socially anxious an individual was, the greater was the left DLPFC activity increased during receipt of messages. This suggests that highly socially anxious people still have the ability to perceive social support, but that they are nevertheless susceptible to negative evaluation by others.

    Comparatively few studies are available reporting at least 5 years of follow-up data of implant-supported single-tooth replacements. To evaluate prospectively the 5-year outcome of implant-supported single-tooth prosthetic restorations. Forty subjects (mean age 41 years), 23 males and 17 females, who required single-tooth prosthetic replacement for a missing tooth were recruited. A total of 45 self-tapping implants (Astra Tech ST-implants)--40 in the maxilla and five in the mandible--were installed in a two-stage procedure. Abutment connection was performed 3-6 months after implant installation. Clinical and radiographic examinations were performed at the completion of the prosthetic treatment and once a year during a 5-year follow-up period. The analysis of peri-implant bone level alteration was performed on subject and implant levels and by the use of analysis of variance and binary logistic regression. Three patients were lost during the 5 years of follow-up. One implant was lost after 2.5 years in function and another four implants could not be accounted for at the 5-year follow-up examination. The overall failure rate at 5 years was 2.6% (subject level) and 2.3% (implant level). The mean loss of marginal bone at the implants during the first year in function was 0.06 mm (SD 0.67) on the subject level and 0.02 mm (0.65) on the implant level. During the subsequent 4 years the annual change in peri-implant bone level amounted to -0.02 mm (0.22) on both subject and implant levels. Thus, the mean total bone level change over the 5-year interval was -0.14 mm (1.04) on subject level and -0.11 mm (1.00) on the implant level of analysis (p>0.05). The frequency of implants with a 5-year bone loss of > or =1 mm was 13%. Approximately 50% of the implants demonstrated no bone loss. The present clinical trial on single-tooth replacements with the Astra Tech implant system demonstrated that the bone loss during the first year of function as well as annually thereafter was

    Full Text Available Abstract Background Residents of rural communities are often more socially connected compared to urban dwellers. Using family and community support to motivate health behavior change may be useful in rural settings. The objective of this study was to pilot a salt reduction (SR intervention for rural albuminuria patients using support from family and neighborhood residents compared to a usual care condition. The primary outcome was change in urine albumin-creatinine ratio (ACR. Methods All consecutive outpatients with an ACR >= 30 mg/gCr were recruited from the Koyadaira Clinic. Patients self-selected their participation in the intervention group (IG or the control group (CG because the rural population expressed concern about not being treated at the same time. In the IG, patients and their families were educated in SR for 30 minutes in their home by experienced dieticians. In addition, patients, families and neighborhood residents were also educated in SR for 2 hours at a public town meeting hall, with educational content encouraging reduction in salt intake through interactive activity. The CG received conventional treatment, and ACR and blood pressure (BP were measured after 3 months. Results Of the 37 subjects recruited (20 male, 16 female, mean age; 72.8 ± 9.2 years, 36 completed the 3-month follow up and were analyzed. In the IG, ACR decreased significantly from baseline (706 ± 1,081 to 440 ± 656; t = 2.28, p = 0.04 and was reduced compared to the CG (213 ± 323 to 164 ± 162; F = 3.50, p = 0.07, a treatment effect approaching significance. Systolic BP in the IG (145 ± 14 to 131 ± 13 mmHg; t = 3.83, p = 0.002 also decreased significantly compared to the CG (135 ± 13 to 131 ± 14; F = 4.40, p = 0.04. Conclusions Simultaneous education of patients, their families and neighborhood residents may be important in rural areas for treatments and interventions requiring health behavior change.

  18. Catalytic property of fiber media supported palladium containing alloy nanoparticles and electrospun ceramic fibers biodurability study

    Shin, Hyeon Ung

    The nanoscale of the supporting fibers may provide enhancements such as restricting the migration of metal catalyst particles. In this work, palladium nanoparticle doped alumina fibers were electrospun into template submicron fibers. These fibers were calcined at temperatures between 650°C and 1150°C to vary the crystal structures of the calcined fibers with the Pd particle size. Higher calcination temperatures led to higher reaction temperatures from 250 to about 450°C for total conversion, indicating the effective reactivity of the fiber-supported catalysts decreased with increase in calcination temperature. Pd-Au alloy nanoparticle doped titania fibers were also fabricated using an electrospinning method and assembled into a fibrous porous medium structure by a vacuum molding process. In reactor tests, the fiber media with Pd-Au alloy nanoparticle catalyst had greater reactivity in conversion of NO and CO gases than that of fiber media with Pd monometallic catalyst alone, attributed to a lower activation energy of the Pd-Au catalyst particles. In carbon monoxide oxidation reaction tests, the results showed that the performance was optimal for a catalyst of composition Pd2Au1 molar ratio that was active at 125°C, which had higher dispersion of active components and better catalytic performance compared to monometallic particle Au/TiO 2 and Pd/TiO2 fiber media. Moreover, the improved reaction activity of Pd2Au1/TiO2 fiber medium was attributed to a decreased in the activation energy. Further experiments were conducted using the electrospun ceramic fibers biodurability study. The properties of nano-sized fiber structures have attracted the attention of recent research on ceramic nanostructures as nonwoven media for applications in hazardous chemical and high temperature environments. However, health and safety concerns of micro and nano scale ceramic materials have not been fully investigated. Little is known about the physicochemical effects of the properties

    This paper describes a study that examined how microbiology students construct knowledge of bacterial identification while using a computer simulation. The purpose of this study was to understand how the simulation affects the cognitive processing of students during thinking, problem solving, and learning about bacterial identification and to determine how the simulation facilitates the learning of a domain-specific problem-solving strategy. As part of an upper-division microbiology course, five students participated in several simulation assignments. The data were collected using think-aloud protocol and video action logs as the students used the simulation. The analysis revealed two major themes that determined the performance of the students: Simulation Usage-how the students used the software features and Problem-Solving Strategy Development-the strategy level students started with and the skill level they achieved when they completed their use of the simulation. SEVERAL CONCLUSIONS EMERGED FROM THE ANALYSIS OF THE DATA: (i) The simulation affects various aspects of cognitive processing by creating an environment that makes it possible to practice the application of a problem-solving strategy. The simulation was used as an environment that allowed students to practice the cognitive skills required to solve an unknown. (ii) Identibacter (the computer simulation) may be considered to be a cognitive tool to facilitate the learning of a bacterial identification problem-solving strategy. (iii) The simulation characteristics did support student learning of a problem-solving strategy. (iv) Students demonstrated problem-solving strategy development specific to bacterial identification. (v) Participants demonstrated an improved performance from their repeated use of the simulation.

    A fundamental attribute of cell membranes is transmembrane asymmetry, specifically the formation of ordered phase domains in one leaflet that are compositionally different from the opposing leaflet of the bilayer. Using model membrane systems, many previous studies have demonstrated the formation of ordered phase domains that display complete transmembrane symmetry but there have been few reports on the more biologically relevant asymmetric membrane structures. Here we report on a combined atomic force microscopy (AFM) and fluorescence microscopy study whereby we observe three different states of transmembrane symmetry in phase-separated supported bilayers formed by vesicle fusion. We find that if the leaflets differ in gel-phase area fraction, then the smaller domains in one leaflet are in registry with the larger domains in the other leaflet and the system is dynamic. In a presumed lipid flip-flop process similar to Ostwald Ripening, the smaller domains in one leaflet erode away while the large domains in the other leaflet grow until complete compositional asymmetry is reached and remains stable. We have quantified this evolution and determined that the lipid flip-flop event happens most frequently at the interface between symmetric and asymmetric DSPC domains. If both leaflets have nearly identical area fraction of gel-phase, gel-phase domains are in registry and are static in comparison to the first state. The stability of these three DSPC domain distributions, the degree of registry observed, and the domain immobility have direct biological significance with regards to maintenance of lipid asymmetry in living cell membranes, communication between inner leaflet and outer leaflet, membrane adhesion, and raft mobility.

    Objectives This qualitative study explores Nigerian health care professionals’ concepts of good dying/a good death and how telemedicine technologies and services would fit the current Nigerian palliative care practice. Materials and Methods Supported by the Centre for Palliative Care Nigeria (CPCN) and the University College Hospital (UCH) in Ibadan, Nigeria, the authors organized three focus groups with Nigerian health care professionals interested in palliative care, unstructured interviews with key role players for palliative care and representatives of telecom companies, and field visits to primary, secondary and tertiary healthcare clinics that provided palliative care. Data analysis consisted of open coding, constant comparison, diagramming of categorizations and relations, and extensive member checks. Results The focus group participants classified good dying into 2 domains: a feeling of completion of the individual life and dying within the community. Reported barriers to palliative care provision were socio-economic consequences of being seriously ill, taboos on dying and being ill, restricted access to adequate medical–technical care, equation of religion with medicine, and the faulty implementation of palliative care policy by government. The addition of telemedicine to Nigeria’s palliative care practice appears problematic, due to irregular bandwidth, poor network coverage, and unstable power supply obstructing interactivity and access to information. However, a tele-education ‘lite’ scenario seemed viable in Nigeria, wherein low-tech educational networks are central that build on non-synchronous online communication. Discussion Nigerian health care professionals’ concepts on good dying/a good death and barriers and opportunities for palliative care provision were, for the greater part, similar to prior findings from other studies in Africa. Information for and education of patient, family, and community are essential to further improve

    Levels of undiagnosed HIV infection and late presentation remain high globally despite attempts to increase testing. The objective of this study was to evaluate a risk-based prototype application to prompt HIV testing when patients undergo routine blood tests. Two computer physician order entry (CPOE) systems were modified using the application to prompt health care workers (HCWs) to add an HIV test when other tests selected suggested that the patient was at higher risk of HIV infection. The application was applied for a 3-month period in two areas, in a large London hospital and in general practices in Teesside/North Yorkshire. At the end of the evaluation period, HCWs were interviewed to assess the usability and acceptability of the prompt. Numbers of HIV tests ordered in the general practice areas were also compared before and after the prompt's introduction. The system was found to be both useable and generally acceptable to hospital doctors, general practitioners and nurse practitioners, with little evidence of prompt/alert fatigue. The issue of the prompt appearing late in the patient consultation did lead to some difficulties, particularly around discussion of the test and consent. In the general practices, around 1 in 10 prompts were accepted and there was a 6% increase in testing rates over the 3-month study period (P = 0.169). Using a CPOE-based clinical decision support application to prompt HIV testing appears both feasible and acceptable to HCWs. Refining the application to provide more accurate risk stratification is likely to make it more effective. © 2016 British HIV Association.

    Diminished social networks are common in psychosis but few studies have measured these comprehensively and prospectively to determine how networks and support evolve during the early phase. There is little information regarding perceived support in the early phase of illness. The aim of this study was to describe social support, networks and perceived satisfaction, explore the clinical correlates of these outcomes and examine whether phases of untreated psychosis are linked with social network variables to determine potential opportunities for intervention. During the study period, we assessed 222 people with first-episode psychosis at entry into treatment using valid and reliable measures of diagnosis, positive and negative symptoms, periods of untreated psychosis and prodrome and premorbid adjustment. For follow-up we contacted participants to conduct a second assessment (n=158). There were 97 people who participated which represented 61% of those eligible. Social network and support information obtained at both time points included the number of friends, self-reported satisfaction with support and social network size and clinician's evaluation of the degree of support received through networks. Mixed effects modelling determined the contribution of potential explanatory variables to social support measured. A number of clinical variables were linked with social networks, support and perceived support and satisfaction. The size of networks did not change over time but those with no friends and duration of untreated psychosis was significantly longer for those with no friends at entry into treatment (n=129, Median=24.5mths, IQR=7.25-69.25; Mann-Whitney U=11.78, p=0.008). Social support at baseline and at one year was predicted by homelessness (t=-2.98, p=0.001, CI -4.74 to -1.21), duration of untreated psychosis (t=-0.86, p=0.031, CI -1.65 to -0.08) and premorbid adjustment (t=-2.26, p=0.017, CI -4.11 to -0.42).

    This paper compares the impacts of health and widowhood on the level of support received by elderly women living in small island communities within the Philippines and Fiji. Using a theoretical perspective of ongoing reciprocal exchange as opposed to altruistic support within household economies, this paper reviews the impacts of disability and economic contributions on the level of support an elderly female receives. It is hypothesized that as the health of the widow declines her access to care will also diminish due to an inability to contribute to the household economies of the extended family. This paper extends existing work on health and family support of widowed females in the developing world by performing a cross-national comparative analysis as well as by explicitly testing the assumptions of altruism that are a central assumption of most models of long-term care in underdeveloped nations.

    Nano-scale Pt particles are often reported to be more electrochemically active and stable in a fuel cell if properly displaced on support materials; however, the factors that affect their activity and stability are not well understood. We applied first-principles calculations and experimental measurements to well-defined model systems of N-doped graphene supports (N-GNS) to reveal the fundamental mechanisms that control the catalytic properties and structural integrity of nano-scale Pt particles. DFT calculations predict thermodynamic and electrochemical interactions between N-GNS and Pt nanoparticles in the methanol oxidation reaction (MOR) and oxygen reduction reaction (ORR). Moreover, the dissolution potentials of the Pt nanoparticles supported on GNS and N-GNS catalysts are calculated under acidic conditions. Our results provide insight into the design of new support materials for enhanced catalytic efficiency and long-term stability.

    Full Text Available Background Change management in health care is a complex and time-consuming endeavour, and no less so in implementing technological systems. In deploying a nationwide programme, the personally controlled electronic health record (PCEHR, the Australian Government employed a number of national and local change management programmes.Objective This article describes the processes undertaken and the experiences of introducing the PCEHR into 74 general practices across a specific area of metropolitan Melbourne.Method An online survey was developed by an independent evaluator and offered to all participating practices. The response rate was 82%.Results The deployment and testing of the eHealth infrastructure and the roll- out of the PCEHR were deeply supported through face-to-face, locally contextualised support processes. The area Medicare Local (ML, an organisation that provides support services to general practice and allied health in the community, provided support and programme coordination. This support occurred in the environment of a number of other initiatives to improve adoption.Conclusion The impact and value of this support in the registration and adoption process was explored in an online survey and found to be the key factor in practice engagement and success. ML support was seen as instrumental in improving adoption and was more effective than other activities. This article highlights the role of local support, in this case, MLs, in the effective implementation of eHealth programmes across a range of stakeholder groups, in particular, general practice, and the potential for the lessons learned from the engagement model of such an entity to be more generally applied.

    Measurements indicate that the development of cracking is a key feature relating to the strength and collapse of a columnar jointed rock mass. In this context, a new support design method utilising rock cracking indices for columnar jointed rock mass under high stress is proposed to restrain the development of cracking in the surrounding rock mass. The method involves limiting the cracking evolution of the surrounding rock mass by designing the appropriate parameters and time of installation of the support system. Two indices are suggested: the allowable depth of the excavation damaged zone (EDZ); and the allowable damage extent of the rock mass in the EDZ. The method involves limiting the evolution of cracking in the surrounding rock mass by designing the parameters and time of installation of the support system. The support system should have a suitable stiffness and installation time so as to restrain the evolution of the depth and damage extent of the EDZ within the surrounding rock. Therefore, the depth and damage extent of the EDZ, as well as the axial stress in the anchor bolts, are calculated at different distances between the support location and the tunnel working face to find the appropriate stiffness and installation time of the support system. The method has been successfully adopted to determine the thickness of shotcrete, the arrangement and installation time of rockbolts, and other parameters, for five large diversion tunnels at the Baihetan hydropower station, China, which were excavated in columnar jointed rock masses.

    Full Text Available Abstract Background Understanding people's social lived experiences of chronic illness is fundamental to improving health service delivery and health outcomes, particularly in relation to self-management activity. In explorations of social lived experiences this paper uncovers the ways in which Aboriginal and Torres Strait Islander people with chronic illness experience informal unsolicited support from peers and family members. Methods Nineteen Aboriginal and Torres Islander participants were interviewed in the Serious and Continuing Illness Policy and Practice Study (SCIPPS. Participants were people with Type 2 diabetes (N = 17, chronic obstructive pulmonary disease (N = 3 and/or chronic heart failure (N = 11 and family carers (N = 3. Participants were asked to describe their experience of having or caring for someone with chronic illness. Content and thematic analysis of in-depth semi-structured interviews was undertaken, assisted by QSR Nvivo8 software. Results Participants reported receiving several forms of unsolicited support, including encouragement, practical suggestions for managing, nagging, growling, and surveillance. Additionally, participants had engaged in 'yarning', creating a 'yarn' space, the function of which was distinguished as another important form of unsolicited support. The implications of recognising these various support forms are discussed in relation to responses to unsolicited support as well as the needs of family carers in providing effective informal support. Conclusions Certain locations of responsibility are anxiety producing. Family carers must be supported in appropriate education so that they can provide both solicited and unsolicited support in effective ways. Such educational support would have the added benefit of helping to reduce carer anxieties about caring roles and responsibilities. Mainstream health services would benefit from fostering environments that encourage informal interactions that

    There is a large empirical basis for the importance of social networks and support for people with a mental illness. However, only a few studies have examined the predictors, changes and correlations of these constructs within a longitudinal framework. To analyze changes in social network diversity as measured by the number of social roles and perceived social support over the course of three years after a psychiatric hospitalization while controlling for sociodemographic and clinical variables. A further aim was to inquire whether some social roles are perceived as being more supportive than others. Random coefficient models were applied to the data of a longitudinal study on the life circumstances of people with affective disorders or schizophrenia (N = 183). The majority of participants had relatives, friends and co-workers, while a markedly smaller proportion had a spouse/partner or children. Social network diversity increased during the time period observed while the perception of social support did not change. Being male, without a job (competitive or sheltered), or having a low income predicted less diverse networks. Partners and friends were perceived as most supportive. Persons without a close friendship perceived less overall support, but only at baseline (hospitalization), while persons with a job on the competitive labor market felt better supported. Social disintegration in the course of mental illness that is found in some studies has no equivalent in our study in what concerns network diversity and perceived support. According to our results, characteristics of vocational and economic integration are of much greater relevance, as they enhance or hinder access to social participation.

    Telehealth is being used increasingly in providing care to patients in the community setting. Telehealth enhanced service delivery could offer new ways of managing load and care prioritisation for palliative care patients living in the community. The study assesses the feasibility of a telehealth-based model of service provision for community based palliative care patients, carers and clinicians. This study was a prospective cohort study of a telehealth-based intervention for community based patients of a specialist palliative care service living in Southern Adelaide, South Australia. Participants were 43 community living patients enrolled in the Southern Adelaide Palliative Service. To be eligible patients needed to be over 18 years and have an Australian modified Karnofksy Performance Score > 40. Exclusion criteria included a demonstrated inability to manage the hardware or technology (unless living with a carer who could manage the technology) or non-English speaking without a suitable carer/proxy. Participants received video-based conferences between service staff and the patient/carer; virtual case conferences with the patient/carer, service staff and patient's general practitioner (GP); self-report assessment tools for patient and carer; and remote activity monitoring (ACTRN12613000733774). The average age of patients was 71.6 years (range: 49 to 91 years). All 43 patients managed to enter data using the telehealth system. Self-reported data entered by patients and carers did identify changes in performance status leading to changes in care. Over 4000 alerts were generated. Staff reported that videocalls were similar (22.3%) or better/much better (65.2%) than phone calls and similar (63.1%) or better/much better (27.1%) than face-to-face. Issues with the volume of alerts generated, technical support required and the impact of service change were identified. The trial showed that patients and carers could manage the technology and provide data that

    Full Text Available Abstract Background The ability to breastfeed and continue the practice requires dedication, commitment, persistence and support. Mothers often need to overcome many obstacles to successfully breastfeed their babies and maintain their balance of home, family and work commitments. Evidence suggests that fathers want to be involved and be part of the parenthood process, including infant feeding. The role transition from couple to family poses challenges to both parents. Sharing the experience of childbirth and supporting each other in the subsequent infant feeding practices is one of those challenges. Methods A qualitative exploratory design was chosen to identify parents' perceptions of what constitutes support for breastfeeding, particularly focusing upon paternal support. Focus groups were conducted with mothers and a focus group, interviews and an online survey were developed for fathers. Thematic analysis was used to identify the main themes. Results From a total of 76 participants, the major theme emerging from mothers' data identified that "Dads do make a difference". Three sub-themes included: Anticipating needs and getting the job done; Encouragement to do your best; and Paternal determination and commitment, associated with effective partner support. "Wanting to be involved" was identified from fathers' data as the major theme around their needs. Three sub-themes included: Wanting more information; Learning the role; and Being an advocate. Conclusion Sharing the experience of childbirth and supporting each other in the subsequent infant feeding practices was perceived as the best outcome for the majority of new mothers and fathers. Paternal emotional, practical and physical supports were identified as important factors to promote successful breastfeeding and to enrich the experience for the mother and subsequently the father.

    Common short bolts of equal length are widely used to support the roofs of roadways in coal mines. However, they are insufficient to keep the roof stable against large deformations, so docking long bolts with high levels of elongation that can adapt to large deformations of the surrounding rock have been adopted. This paper proposes a collaborative support method that uses long and short bolts. In this study, the mechanism of docking long bolts and collaborative support was studied. Numerical simulation, sim-ilarity simulation, and field testing were used to analyze the distribution law of the displacement, stress, and plastic failure in the surrounding rock under different support schemes. Compared with the equal-length short bolt support, the collaborative support changed the maximum principal stress of the shallow roof from tensile stress to compressive stress, and the minimum principal stress of the roof significantly increased. The stress concentration degree of the anchorage zone clearly increased. The deformation of the roof and the two sides was greatly reduced, and the subsidence shape of the shallow roof changed from serrated to a smooth curve. The roof integrity was enhanced, and the roof moved down as a whole. Plastic failure significantly decreased, and the plastic zone of the roof was within the anchorage range. The similarity simulation results showed that, under the maximum mining stress, the roof collapsed with the equal-length short bolt support but remained stable with the collaborative support. The collaborative support method was successfully applied in the field and clearly improved the stability of the surrounding rock for a large deformation roadway.

    The aim of this study was to evaluate prospectively the 12-year outcome of implant-supported single-tooth restorations. Originally 45 self-tapping Astra Tech TiOblast(®) ST-implants were installed by a two-stage protocol in 40 subjects requiring single-tooth prosthetic replacement for a missing tooth. Clinical and radiologic examinations were performed at completion of the prosthetic treatment 4-7 months after implant installation surgery and after 5 and 12 years in function. At 12 years 31 patients and 35 implants were available for evaluation. The overall failure rate after 12 years was 10.3% on the subject level and 9.1% on the implant level. The mean bone loss amounted to 0.67 mm (SD 2.20) on a subject level and 0.47 mm (1.72) on an implant level. Three subjects (10%) and three implants (8.6%) were diagnosed with peri-implantitis. Five subjects had experienced technical complications; three incidences of loosening of the abutment retention screw during the first 5 years and two minor porcelain fracture of the crown (two patients) between 5- and 12-years of follow-up. The findings reported in this 12-year prospective case series suggest that the use of the Astra Tech dental implants may be a valid treatment alternative for single-tooth replacement prostheses. © 2015 John Wiley & Sons A/S.

    The aims of our study were to: (1) develop the Disability Grading Decision Support System (DGDSS) and to (2) compare the new International Classification of Functioning, Disability, and Health (ICF)-based disability determination tool (ICF-DDT) with the diagnosis-based disability determination tool (D-DDT). A total of 9357 patients recruited from 236 accredited institutions were evaluated using the ICF-DDT and the D-DDT, and the presence, severity, and category of the disability identified using the two determination tools were compared. In the DGDSS, the ICF-DDT consisted of four models comprising nine modules to determine the presence and the severity of the disability. The differences between models (modules) are the different combinations of World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) and Scale of Body Functions and Structures. Compared with the D-DDT, more patients were determined to be disability-free when using the ICF-DDT. Module 1-1 had the highest profoundly severe rate, and module 2-2 had the highest mild and moderate disability rates. Module 2-1 had the highest severe disability rate. Module 1-1 resulted in the smallest difference, and module 3-1 resulted in the largest difference, compared with the D-DDT. Feedback from users suggested that the DGDSS is a robust system if the original data are accurate. The presence, severity, and category of the disability determined using the ICF-DDT and the D-DDT were significantly different. The results of the DGDSS provide information for policymakers to determine the optimal allocation of social welfare and medical resources for people with disabilities. Copyright © 2013.

    Full Text Available Abstract Background In an out-of-hospital emergency situation bystander intervention is essential for a sufficient functioning of the chain of rescue. The basic measures of cardiopulmonary resuscitation (Basic Life Support – BLS by lay people are therefore definitely part of an effective emergency service of a patient needing resuscitation. Relevant knowledge is provided to the public by various course conceptions. The learning success concerning a one day first aid course ("LSM" course in Germany has not been much investigated in the past. We investigated to what extent lay people could perform BLS correctly in a standardised manikin scenario. An aim of this study was to show how course repetitions affected success in performing BLS. Methods The "LSM course" was carried out in a standardised manner. We tested prospectively 100 participants in two groups (Group 1: Participants with previous attendance of a BLS course; Group 2: Participants with no previous attendance of a BLS course in their practical abilities in BLS after the course. Success parameter was the correct performance of BLS in accordance with the current ERC guidelines. Results Twenty-two (22% of the 100 investigated participants obtained satisfactory results in the practical performance of BLS. Participants with repeated participation in BLS obtained significantly better results (Group 1: 32.7% vs. Group 2: 10.4%; p Conclusion Only 22% of the investigated participants at the end of a "LSM course" were able to perform BLS satisfactorily according to the ERC guidelines. Participants who had previously attended comparable courses obtained significantly better results in the practical test. Through regular repetitions it seems to be possible to achieve, at least on the manikin, an improvement of the results in bystander resuscitation and, consequently, a better patient outcome. To validate this hypothesis further investigations are recommended by specialised societies.

  17. Bioassay studies support the potential for iatrogenic transmission of variant Creutzfeldt Jakob Disease through dental procedures.

    Elizabeth Kirby

    Full Text Available BACKGROUND: Evidence is required to quantify the potential risks of transmission of variant Creutzfeldt Jakob (vCJD through dental procedures. Studies, using animal models relevant to vCJD, were performed to address two questions. Firstly, whether oral tissues could become infectious following dietary exposure to BSE? Secondly, would a vCJD-contaminated dental instrument be able to transmit disease to another patient? METHODS: BSE-301V was used as a clinically relevant model for vCJD. VM-mice were challenged by injection of infected brain homogenate into the small intestine (Q1 or by five minute contact between a deliberately-contaminated dental file and the gingival margin (Q2. Ten tissues were collected from groups of challenged mice at three or four weekly intervals, respectively. Each tissue was pooled, homogenised and bioassayed in indicator mice. FINDINGS: Challenge via the small intestine gave a transmission rate of 100% (mean incubation 157±17 days. Infectivity was found in both dental pulp and the gingival margin within 3 weeks of challenge and was observed in all tissues tested within the oral cavity before the appearance of clinical symptoms. Following exposure to deliberately contaminated dental files, 97% of mice developed clinical disease (mean incubation 234±33 days. INTERPRETATION: Infectivity was higher than expected, in a wider range of oral tissues, than was allowed for in previous risk assessments. Disease was transmitted following transient exposure of the gingiva to a contaminated dental file. These observations provide evidence that dental procedures could be a route of cross-infection for vCJD and support the enforcement of single-use for certain dental instruments.

    A key scientific objective of the original Boreal Ecosystem-Atmospheric Study (BOREAS) field campaign (1993-1996) was to obtain the baseline data required for modeling and predicting fluxes of energy, mass, and trace gases in the boreal forest biome. These data sets are necessary to determine the sensitivity of the boreal forest biome to potential climatic changes and potential biophysical feedbacks on climate. A considerable volume of remotely-sensed and supporting field data were acquired by numerous researchers to meet this objective. By design, remote sensing and modeling were considered critical components for scaling efforts, extending point measurements from flux towers and field sites over larger spatial and longer temporal scales. A major focus of the BOREAS follow-on program is concerned with integrating the diverse remotely sensed and ground-based data sets to address specific questions such as carbon dynamics at local to regional scales. The Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) has the potential of contributing to BOREAS through: (1) accurate retrieved apparent surface reflectance; (2) improved landcover classification; and (3) direct assessment of biochemical/biophysical information such as canopy liquid water and chlorophyll concentration through pigment fits. In this paper, we present initial products for major flux tower sites including: (1) surface reflectance of dominant cover types; (2) a land-cover classification developed using spectral mixture analysis (SMA) and Multiple Endmember Spectral Mixture Analysis (MESMA); and (3) liquid water maps. Our goal is to compare these land-cover maps to existing maps and to incorporate AVIRIS image products into models of photosynthetic flux.

    Full Text Available Abstract Background Although some interventions have been shown to improve adherence to medication for diabetes, results are not consistent. We have developed a theory-based intervention which we will evaluate in a well characterised population to test efficacy and guide future intervention development and trial design. Methods and Design The SAMS (Supported Adherence to Medication Study trial is a primary care based multi-centre randomised controlled trial among 200 patients with type 2 diabetes and an HbA1c of 7.5% or above. It is designed to evaluate the efficacy of a two-component motivational intervention based on the Theory of Planned Behaviour and volitional action planning to support medication adherence compared with standard care. The intervention is delivered by practice nurses. Nurses were trained using a workshop approach with role play and supervised using assessment of tape-recorded consultations. The trial has a two parallel groups design with an unbalanced three-to-two individual randomisation eight weeks after recruitment with twelve week follow-up. The primary outcome is medication adherence measured using an electronic medication monitor over 12 weeks and expressed as the difference between intervention and control in mean percentage of days on which the correct number of medication doses is taken. Subgroup analyses will explore impact of number of medications taken, age, HbA1c, and self-reported adherence at baseline on outcomes. The study also measures the effect of dispensing medication to trial participants packaged in the electronic medication-monitoring device compared with conventional medication packaging. This will be achieved through one-to-one randomisation at recruitment to these conditions with assessment of the difference between groups in self-report of medication adherence and change in mean HbA1c from baseline to eight weeks. Anonymised demographic data are collected on non-respondents. Central randomisation

    Although the association between social support and postpartum depression has been previously investigated, its causal relationship remains unclear. Therefore, we examined prospectively whether social support during pregnancy affected postpartum depression. Social support and depressive symptoms were assessed by Japanese version of Social Support Questionnaire (J-SSQ) and Edinburgh Postnatal Depression Scale (EPDS), among 877 pregnant women in early pregnancy and at one month postpartum. First, J-SSQ was standardized among peripartum women. The J-SSQ was found to have a two-factor structure, with Number and Satisfaction subscales, by exploratory and confirmatory factor analyses. Analysis of covariance was performed to examine how EPDS and J-SSQ scores during pregnancy affected the EPDS score at postpartum. Significant associations were found between postpartum EPDS score and both EPDS and total scores on the Number subscales during pregnancy (β = 0.488 and -0.054, ps supportive persons during pregnancy helps protect against postpartum depression, and that this effect is greater in depressive than non-depressive pregnant women. This finding is expected to be vitally important in preventive interventions.

  1. Sustaining Lesson Study: Resources and Factors that Support and Constrain Mathematics Teachers' Ability to Continue After the Grant Ends

    Science.gov (United States)

    Druken, Bridget Kinsella

    Lesson study, a teacher-led vehicle for inquiring into teacher practice through creating, enacting, and reflecting on collaboratively designed research lessons, has been shown to improve mathematics teacher practice in the United States, such as improving knowledge about mathematics, changing teacher practice, and developing communities of teachers. Though it has been described as a sustainable form of professional development, little research exists on what might support teachers in continuing to engage in lesson study after a grant ends. This qualitative and multi-case study investigates the sustainability of lesson study as mathematics teachers engage in a district scale-up lesson study professional experience after participating in a three-year California Mathematics Science Partnership (CaMSP) grant to improve algebraic instruction. To do so, I first provide a description of material (e.g. curricular materials and time), human (attending district trainings and interacting with mathematics coaches), and social (qualities like trust, shared values, common goals, and expectations developed through relationships with others) resources present in the context of two school districts as reported by participants. I then describe practices of lesson study reported to have continued. I also report on teachers' conceptions of what it means to engage in lesson study. I conclude by describing how these results suggest factors that supported and constrained teachers' in continuing lesson study. To accomplish this work, I used qualitative methods of grounded theory informed by a modified sustainability framework on interview, survey, and case study data about teachers, principals, and Teachers on Special Assignment (TOSAs). Four cases were selected to show the varying levels of lesson study practices that continued past the conclusion of the grant. Analyses reveal varying levels of integration, linkage, and synergy among both formally and informally arranged groups of

    Clinical studies and preclinical investigations are essential in order to test new therapies and diagnostics with the aim of sustained improvement in the treatment of patients. Fortunately, the number of clinical studies is continuously increasing and pathology and tissue-based research are included more often. The German Society for Pathology (DGP) and the pathologists it represents want to and can support this process and our clinical partners as best as possible as an equal partner. With our technologies and our specific expertise we can make a substantial contribution to the quality and the success of preclinical investigations, clinical studies and implementation of the results into clinical pathological diagnostics. In order to support this process the DGP has formulated a statement on the participation and support of clinical studies and other scientific investigations.

    In Mediterranean Countries the proper management of water resources is important for the preservation of actual production systems. The possibility to manage water resources is possible especially in the greenhouses systems. The challenge to manage the soil in greenhouse farm can be a strategy to maintain both current production systems both soil conservation. In Campania region protected crops (greenhouses and tunnels) have a considerable economic importance both for their extension in terms of surface harvested and also for their production in terms of yields. Agricultural production in greenhouse is closely related to the micro-climatic condition but also to the physical and agronomic characteristics of the soil-crop system. The protected crops have an high level of technology compare to the other production systems, but the irrigation management is still carried out according to empirical criteria. The rational management of the production process requires an appropriate control of climatic parameters (temperature, humidity, wind) and agronomical inputs (irrigation, fertilization,). All these factors need to be monitored as well is possible, in order to identify the optimal irrigation schedule. The aim of this work is to implement a Decision Support system -DSS- for irrigation management in greenhouses focused on a smart irrigation control based on observation of the agro-climatic parameters monitored with an advanced wireless sensors network. The study is conducted in a greenhouse farm of 6 ha located in the district of Salerno were seven plots were cropped with rocket. Preliminary a study of soils proprieties was conducted in order to identify spatial variability of the soil in the farm. So undisturbed soil samples were collected to define chemical and physical proprieties; moreover soil hydraulic properties were determined for two soils profiles deemed representation of the farm. Then the wireless sensors, installed at different depth in the soils

    One of the most promising applications of the new field of coastal altimetry, i.e. the discipline aiming to recover meaningful estimates of geophysical parameters (sea level, significant wave height and wind speed) from satellite altimeter data in the coastal zone, is the study of storm surges. The understanding and realistic modelling of surges supports both preparation and mitigation activities and should eventually bring enormous societal benefits, especially to some of the world's poorest countries (like Bangladesh). Earth Observation data have an important role to play in storm surge monitoring and forecasting, but the full uptake of these data by users (such as environmental agencies and tidal prediction centres) must first be encouraged by showcasing their usefulness, and then supported by providing easy access. Having recognized the above needs, The European Space Agency has recently launched a Data User Element (DUE) project called eSurge. The main purposes of eSurge are a) to contribute to an integrated approach to storm surge, wave, sea-level and flood forecasting through Earth Observation, as part of a wider optimal strategy for building an improved forecast and early warning capability for coastal inundation; and b) to increase the use of the advanced capabilities of ESA and other satellite data for storm surge applications. The project is led by Logica UK, with NOC (UK), DMI (Denmark), CMRC (Ireland) and KNMI (Netherlands) as scientific partners. A very important component of eSurge is the development, validation and provision of dedicated coastal altimetry products, which is the focus of the present contribution. Coastal altimetry has a prominent role to play as it measures the total water level envelope directly, and this is one of the key quantities required by storm surge applications and services. But it can also provide important information on the wave field in the coastal strip, which helps the development of more realistic wave models that in

    Support services in providing PACS to healthcare facilities are becoming more complex. Imaginative staffing models are imperative to provide a successful PACS program to customers. Choosing the right staffing grid of support staff can be assisted by locations with like volumes or geographic areas. The RIT (radiology information technology) specialist is an excellent asset in a growing PACS environment. RITs can be the crucial liaison between the radiology department and the customer. RITs with different backgrounds can be recruited based on what type of support services your customers need. RITs are a great resource for one-on-one training from physicians to nursing staff. This mobile PACS spokesperson can take the concerns of the customers to the PACS administrator to open dialogue and communication that will win customer loyalty in this ever changing world of technology.

    We have been developing exoskeletal robots in order to realize the human motion support (especially for physically weak people). In this paper, we propose a 2-DOF exoskeletal robot and its method of control to support the human shoulder motion. In this exoskeletal robot, the flexion-extension and abduction-adduction motions of the shoulder are supported by activating the arm holder of the robot, which is atached to the upper arm of the human subject, using wires driven by DC motors. A fuzzy-neuro controller is designed to control the robot according to the skin surface electromyogram(EMG) signals in which the intention of the human subject is reflected. The proposed controller controls the flexion-extension and abduction-adduction motion of the human subject. The effectiveness of the proposed exoskeletal robot has been evaluated experimentally.

    The effects of O2 and the supported Pt nano-particles on the mechanisms and kinetics of the carbon support corrosion are investigated by monitoring the CO2 production using differential electrochemical mass spectrometry in a dual-thin layer flow cell. Carbon can be oxidized in different distinct potential regimes; O2 accelerates carbon oxidation, the rates of CO2 production from carbon oxidation in O2 saturated solution are two times of that in N2 saturated solution at the same potential; Pt can catalyze the carbon oxidation, with supported Pt nanoparticles, the overpotential for carbon oxidation is much smaller than that without loading in the carbon electrode. The mechanism for the enhanced carbon oxidation by Pt and O2 are discussed.

    This paper reports mainly the preparation of silica supported acetylacetone ligands and their cobalt complexes, the characterization of their chemical structure, and the evaluation of their catalytic activity in the reaction for the preparation of ethers directly from alkanols and benzyl chloride. The results indicate that those silica supported β-diketone cobalt complexes (SACO) not only can simplify the reaction procedure of the ether preparation but also show a much higher catalytic activity in comparison with other homogeneous catalysts. In addition, SACO can be recovered and reused although their catalytic activity descend gradually as a result of the decrease in their cobalt content.

    Objective: The associations between social support and burnout were explored in ICU nurses of Shanghai. Methods: We performed a cross-sectional study of 356 ICU nurses by applying random cluster sampling. Data were collected using self-reported questionnaires under the instruction of trained investigators. Data on emotional exhaustion, depersonalisation and feelings of low personal ac-complishment etc. were collected, calculated and analyzed. Results: The participants had a mean age of 26. 96 years ( SD 4. 07) . The mean value ( M) and stand-ard deviation ( SD) of emotional exhaustion was M=31. 85, SD=8. 38, those of depersonalisation was M=11. 69, SD=5. 54 and those of feelings of low personal accomplishment was M=19. 79, SD=7. 02. The high degree of emotional exhaustion ( EE) , depersonalisation ( DP) , and lack of personal accom-plishment ( PA) were revealed to be 76. 4%, 39. 6%, and 94. 9%, respectively. The major influencing factors of emotional exhaustion included support from co-workers( b=0. 343, t=1. 98, P=0. 049) , tak-ing leave( b=-1. 182, t=-3. 747, P=0. 001) , requisition of work( b=-1. 41, t=-2. 369, P=0. 018) , and supervisor support( b=-0. 524, t=-3. 926, P=0. 001) . The major influencing factors of depersonalisa-tion were support from the supervisor( b=-0. 333, t=-4. 146, P=0. 001) , age( b=-0. 89, t=-2. 272, P=0. 024) and requisition of work( b=-0. 148, t=-2. 124, P=0. 034) . There was a positive co-relationship between personal accomplishment and supervisor support. Conclusions: Supervisor support, age, and requisition of work were the major influencing fac-tors of depersonalisation. In addition, supervisor support plays an important role in low personal accomplishment. Further research should focus on supervisor support, co-worker support, time on leave, and requisition of work associated with emotional exhaustion.

    Supporting and training the next generation of researchers is crucial to continuous knowledge and leadership in Arctic research. An increasing number of Arctic organizations have developed initiatives to provide travel support for Early Career Researchers (ECRs) to participate in workshops, conferences and meetings and to network with internationally renowned scientific leaders. However, there has been little evaluation of the effectiveness of these initiatives. As a contribution to the 3rd International Conference on Arctic Research Planning, a study was conducted to analyze the career paths of ECRs who received travel funding from the International Arctic Science Committee between the start of the International Polar Year (2007-2008) and 2013. Two surveys were used: one sent to ECRs who received IASC travel support and one as a specific event study to those unsuccessfully applied for IASC travel support to the IPY 2010 Conference. The results of the surveys indicate that travel support was beneficial to both the research and careers of the respondents, especially if the ECR was engaged with a task or responsibility at the event. Survey responses also included suggestions on how funds could be better used to support the next generation of Arctic researchers.

    Full Text Available Despite extensive research on stress among hospital nurses, the important effects of support and stress on care quality are not yet well established. Similar to other jobs, nurses face stress in their routine working day. The relationship between occupational stress, social support and factors relating to each of them, among Iranian nurses are attempted to correlate. This cross-sectional analytical-descriptive study was carried out in 2013 in Zanjan province where 248 nurses filled the given questionnaires including Demographic data, Work Factors, Nursing Stress Scale, and Social Integration Scale. Data were analyzed using SPSS 16.00. In our study, we found that the stress and social support were significantly correlated. Our findings revealed a significant relation between social supports and occupational stress in nurses. Conclusively, support from supervisors and coworkers can help control nurses’ stress. In addition, both social support and occupational stress are related to three major components: job satisfaction, job security and others' attitude towards nursing. Therefore, creating a positive attitude towards nursing in society, and a suitable working environment for them is a way to increase their efficiency.

    Full Text Available In the context of an innovative teaching project approved by the Government of Aragon and the University of Zaragoza a study on professional training for young people with intellectual disabilities (ID was developed. The objective was to investigate the support system and to check the effectiveness of a design based on sources of natural and professional support. 9 young people with DI took part together with diverse support staff –parents, volunteers, university students through a service learning experience, professionals, adults with ID–. The theoretical bases of the project were linked to independent life projects, the supported employment and the supports model. The methodological references were the mediational teaching approach and cooperative learning. As evaluation tools, the Adaptive Skills Inventory (CALS, the questionnaire of social interaction skills (CHIS and the questionnaires of satisfaction were used.

    The purpose of this study was to assess the relationship between diabetes self-care, diabetes-specific emotional distress, and social support and glycemic control (hemoglobin A1C levels: HbA1c) among a sample of Lebanese adults with type 2 diabetes. A descriptive correlational design was adapted with descriptive statistics and multiple logistic regressions for analyses. A convenience sample of 140 adults diagnosed with type 2 diabetes was recruited from 2 diabetes clinics in Greater Beirut. Participants were asked to complete 4 questionnaires in Arabic. Significant associations (P < .05) were found between following a general diet for more than 3.5 days per week and higher social support and HbA1c levels of 7% or more. Social support was positively associated with HbA1c levels such that participants with uncontrolled glycemic levels, as evidenced by higher values for HbA1c, received more support from their social network.

    Long-term safety assessments for the disposal of radioactive waste in Spain involve the demonstration that annual radiation doses to humans due to potential releases of radionuclides from the waste disposal facility into the biosphere will satisfy the regulatory criteria. For several years, CIEMAT has been developing, for ENRESA, a conceptual approach and tool to support modelling of the migration and accumulation of radionuclides within environmental media once those radionuclides have been released to some component of the biosphere (atmosphere, water bodies or soils). The CIEMAT modelling approach calculates the concentrations of radionuclides in different components of the biosphere and then the calculated radionuclide concentrations are used to estimate the radiation doses to humans due to various exposure paths. In this paper, we not only describe the methodology and modelling approach, we also describe recent developments of that approach to better quantify the resultant doses to humans. First, we present recent developments in the mathematical model for the behaviour of {sup 79}Se and {sup 238}U-series radionuclides in soils and their uptake by plants, taking into account seasonal variations in soil hydrology in Spain. Initial studies with the model that are reported here demonstrate that it is a powerful tool for exploring the behaviour of redox-sensitive radionuclides and {sup 238}U decay chain members in soil-plant systems under different hydrological regimes. In particular, it permits studies of the degree to which secular equilibrium assumptions are appropriate when modelling the {sup 238}U decay chain. Further studies are currently being undertaken examining sensitivities of model results to input parameter values and also applying the model to sites contaminated with {sup 238}U-series radionuclides. It is anticipated that results from these studies will also be reported. A particular interest in biosphere safety assessment is how environmental

    Full Text Available Introduction:Each year more families are confronted with unique challenges related to raising a child with ASD. Parenting stress is a significant aspect of fulfilling the role as a parent, and having a child with ASD greatly influences the experienced stress. The literature review indicates that parenting stress is inversely proportional to family support and coping mechanisms. Aim:Appraising the stress level among parents of children with ASD, the coping mechanisms and the level of family support, in comparison with parents of children diagnosed with ID. Method:A group of parents of children with ASD (N=35 and a second group of children with ID (N=35 completed four questionnnaires: PSI-SF, Brief COPE, FSS and demographic questionnaire. The data was analyzed using t-test for comparison, Chi-square test for comparing frequency distributions and Pearson coefficient for correlation, with psupport (r=-0.415 is a key buffer and coping mechanism for managing the stress in parents of children with ASD. Conclusion:There are no differences in the level of stress, coping mechanisms and the level of support comparing parents of children with ASD and ID.
