As advanced grid-support functions (AGF) become more widely used in grid-connected photovoltaic (PV) inverters, utilities are increasingly interested in their impacts when implemented in the field. These effects can be understood by modeling feeders in real-time systems and testing PV inverters using power hardware-in-the-loop (PHIL) techniques. This paper presents a novel feeder model reduction algorithm using a Monte Carlo method that enables large feeders to be solved and operated on real-time computing platforms. Two Hawaiian Electric feeder models in Synergi Electric's load flow software were converted to reduced order models in OpenDSS, and subsequently implemented in the OPAL-RT real-time digital testing platform. Smart PV inverters were added to the real-time model with AGF responses modeled after characterizing commercially available hardware inverters. Finally, hardware inverters were tested in conjunction with the real-time model using PHIL techniques so that the effects of AGFs on the choice feeders could be analyzed.

Garlic (Allium sativum) is known for its innumerable biological activities including immunomodulation. Aged garlic extract (AGE), an odorless garlic preparation, has been shown to have superior immunomodulatory properties over raw garlic extract. Although garlic is a very rich source of fructans (17%, fresh weight basis), AGE contains only 0.22% of raw garlic fructans. Aged garlic fructans (AGF) have recently been shown to possess immunomodulatory activities in vitro. Natural adjuvants capable of eliciting better immune response of a model antigen are important in developing newer vaccines. In the present study, the adjuvant activity of AGF has been investigated in BALB/c mice using ovalbumin (OVA, 30 µg) as an experimental antigen. The body weights of animals did not change significantly indicating that the administration of garlic fructans is well-tolerated. AGF produce a significant humoral (serum IgG) response to OVA in BALB/c mice administered mucosally by either intranasal or oral route--a delayed response appearing on 50th day at a dose of 30 µg AGF by intranasal route. However, the serum IgG response was seen earlier on 35th day at a dose of 100 µg AGF by oral route. Higher concentrations of AGF (>50 µg) were inhibitory for adjuvant activity by intranasal administration. These observations indicate that AGF display immunoadjuvant activity for a test antigen though the humoral immune response is delayed.

An elegant method is used to prepare silver monoliths with Pluronic F-127(F-127) as sacrificial template by modified sol-gel method. Si nanoparticles (SiNPs) and graphene oxide (GO) are added in situ to Ag/F-127 hydrogel for the reduction of ο-nitroaniline (ο-NA) to 1, 2-benzenediamine. Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Thermogravimetric analysis (TGA), Raman Spectroscopy, Powder X-Ray Diffraction (PXRD) analysis and Brunauer-Emmett-Teller (BET) Nitrogen adsorption techniques were used for characterization of monoliths. An epoch-making catalytic activity of Ag/F-127/GO monoliths is observed in the reduction of ο-NA to 1, 2-benzenediamine in presence of NaBH{sub 4} in aqueous media. The catalyst Ag/F-127/GO took only 2 min which is the minimum time reported so far with significant rate constant claimed itself a leading catalyst for the reduction of ο-NA to 1,2-benzenediamine. Pseudo first order rate constant (k) and Turn over frequency (TOF) values are 0.231 min{sup −1} and 30.053×10{sup 19} molecules min{sup −1} respectively suggest that the catalyst has industrial importance. Recyclability and stability of Ag/F-127/GO catalyst are studied successfully up to 10 cycles. Energy of activation (E{sub a}), and thermodynamic parameters viz. activation enthalpy (ΔH{sup ≠}), activation Gibbs free energy (ΔG{sup ≠}), and entropy of activation (ΔS{sup ≠}) were also ascertained. Catalytic activities of Ag/F-127, Ag/F-127/Dextran, Ag/F-127/Trimethylbenzene (TMB), Ag/F-127/SiNPs, and Ag/F-127/Si/GO monoliths were also studied. - Graphical abstract: Significant catalytic activities of silver monoliths against the reduction of ο-NA to 1,2 benzenediamine. - Highlights: • A new catalyst synthesized Ag/F-127/GO for the reduction of ο- NA to 1, 2- benzenediamine took only 2 min. • Turn over frequency of as synthesized catalyst was 30.053×10{sup 19} molecules min{sup �

Design and development of an active Gurney flap for rotorcraft

2013-03-01

The EU's Green Rotorcraft programme will develop an Active Gurney Flap (AGF) for a full-scale helicopter main rotor blade as part of its `smart adaptive rotor blade' technology demonstrators. AGFs can be utilized to provide a localized and variable lift enhancement on the rotor, enabling a redistribution of loading on the rotor blade around the rotor azimuth. Further advantages include the possibility of using AGFs to allow a rotor speed reduction, which subsequently provides acoustic benefits. Designed to be integrable into a commercial helicopter blade, and thereby capable of withstanding real in-flight centrifugal loading, blade vibrations and aerodynamic loads, the demonstrator is expected to achieve a high technology readiness level (TRL). The AGF will be validated initially by a constant blade section 2D wind tunnel test and latterly by full blade 3D whirl tower testing. This paper presents the methodology adopted for the AGF concept topology selection, based on a series of both qualitative and quantitative performance criteria. Two different AGF candidate mechanisms are compared, both powered by a small commercial electromagnetic actuator. In both topologies, the link between the actuator and the control surface consists of two rotating torque bars, pivoting on flexure bearings. This provides the required reliability and precision, while making the design virtually frictionless. The engineering analysis presented suggests that both candidates would perform satisfactorily in a 2D wind tunnel test, but that equally, both have design constraints which limit their potential to be further taken into a whirl tower test under full scale centrifugal and inertial loads.

The Study Group of the Large-scale Research Institutes (AGF) has been reporting on these projects since 1972, in its programme for 'Environmental and Climate Research'. The programme, which is worked out by the AGF's Coordination Office for Environmental Research, is closely connected with the programmes of the Federal Government; it is revised and updated periodically by the AGF's Coordination Committees for 'Environmental Research' and 'Climate Research'. The 1988/89 programme gives an up-to-date overview of research projects in the field of 'Research and Technology for Health, Nutrition and the Environment' financed with the AGF programme budget of 1988. At the same time, however, it also documents projects of other areas of the programme concerned with environmental issues. Development trends are also discernible in the specification of the goals for 1989. The figures mentioned in the present programme are not comparable with those of earlier programmes, owing to inclusion of the programme section concerned with issues of climate, and to structural changes.

Middle manager resistance is often described as a major challenge for upper-level administrators seeking to implement complex innovations such as evidence-based protocols or new skills training. However, factors influencing middle manager support for innovation implementation are currently understudied in the U.S. health care literature. This article examined the factors that influence middle managers' support for and participation in the implementation of work-based learning, a complex innovation adopted by health care organizations to improve the jobs, educational pathways, skills, and/or credentials of their frontline workers. We conducted semistructured interviews and focus groups with 92 middle managers in 17 health care organizations. Questions focused on understanding middle managers' support for work-based learning as a complex innovation, facilitators and barriers to the implementation process, and the systems changes needed to support the implementation of this innovation. Factors that emerged as influential to middle manager support were similar to those found in broader models of innovation implementation within the health care literature. However, our findings extend previous research by developing an understanding about how middle managers perceived these constructs and by identifying specific strategies for how to influence middle manager support for the innovation implementation process. These findings were generally consistent across different types of health care organizations. Study findings suggest that middle manager support was highest when managers felt the innovation fit their workplace needs and priorities and when they had more discretion and control over how it was implemented. Leaders seeking to implement innovations should consider the interplay between middle managers' control and discretion, their narrow focus on the performance of their own departments or units, and the dedication of staff and other resources for empowering their

Full Text Available This paper aims to identify, discuss and analyze students’ collaboration factors related to distributed leadership (DL, which correlates with interaction quality evident in idea generation. Scripting computer-supported collaborative e-learning (CSCeL activities based on DL can scaffold students’ interactions that support collaboration and promote idea generation. Furthermore, the associated tools can facilitate collaboration via scripting and shed light on students’ interactions and dialogical sequences. Such detailed planning can result in effective short e-courses. In this case study, 21 MSc students’ teams worked on a DL project within a 2-day e-course at the IT Institute (ITIN, France. The research methods involved a self-reported questionnaire; the Non-Negative Matrix Factorization (NNMF algorithm with qualitative analysis; and outcomes from the Social Network Analysis (SNA tools implemented within the forums. The results indicated that scripting DL based on the identified distributed leadership attributes can support values such as collaboration and can be useful in supporting idea generation in short e-courses.

Reaching individuals who can benefit from evidence-based health promotion and disability prevention programs is a goal of federal, state, and local agencies as well as researchers, providers, community agencies, and other stakeholders. Implementation effectiveness at the organizational level must be achieved in order to reach these individuals and sustain the program. This mixed methods study examined eight organizations within two states that successfully implemented the Chronic Disease Self-Management Program (CDSMP) and sustained it from 4 to 10 years. There were two types of organizations: aging services and health care. Internal and external implementation factors and influences were explored. Additional examination of state activities (as a key external agent supporting CDSMP implementation) was conducted. The examination found agreement among the eight organizations regarding why they had adopted the CDSMP - citing the alignment between the program and their organizations' mission and purpose to improve health status and promote better self-care, and the demonstrated value (benefits) of the program. Organizations were also alike in that they described the importance of an internal champion and supportive senior leader. Organizations differed in how they experienced and valued peer support and collaborative networks. Organizations also differed in how they filled their CDSMP workshops. Internal drivers and capability were more often discussed as facilitating successful implementation than external factors. However, state activities and external support enabled successful adoption - particularly funding and training. The primary challenges identified by this set of organizations included difficulty in recruiting participants (filling workshops) and irregular or insufficient funding sources. These challenges were identified as significant and represented barriers to sustaining the program.

Intrapersonal, interpersonal, and contextual risk factors for overprovision of partner support in marriage.

Science.gov (United States)

Brock, Rebecca L; Lawrence, Erika

2014-02-01

Recent research indicates that receiving too much support from one's spouse (i.e., overprovision of support) is actually more detrimental to marriage than not receiving enough support. The principal goal of the present study was to develop a novel framework for explaining the pathways through which couples experience overprovision of support in their marriages. Intrapersonal factors (anxious and avoidant attachment), interpersonal factors (conflict management and emotional intimacy), and contextual factors (stress originating outside of the marriage) were assessed during the transition into marriage as potential risk factors for experiencing higher levels of support overprovision during the first 5 years of marriage in a sample of 103 couples using growth curve analytic techniques. To the extent that (a) husbands were higher in avoidant attachment, (b) husbands reported greater chronic role strain, and (c) couples had lower levels of emotional intimacy, support overprovision was greater for both husbands and wives. In addition, emotional intimacy (lower levels) was a partial pathway through which husband avoidant attachment contributed to support overprovision. Finally, factors placing couples at risk for support overprovision in their marriages appear to be distinct from those increasing the risk for support underprovision. The potential for results to inform contemporary marital theories and marital preparation programs is discussed.

At the new tunnel construction site of the Shirakata tunnel on the Obama line in Yamaguchi Prefecture, a landsliding occurred at about 60 meters to the upper portion obliquely to the right hand side of the shaft when the excavation progressed to about 10 meters from the starting side. The landslide caused displacement at the shaft opening and change in the supports. As a result of the re-investigation, it was confirmed that the slide face went through the tunnel cross section. The measures taken were removal of the upper soil and an adoption of the all ground fastening (AGF) method (injection type long tip fastening method) as an auxiliary construction to stop loosening of the natural ground associated with the tunnel excavation. The result was a completion of tunneling the landsliding zone without a problem. This paper reports the AGF method adopted in the above construction, together with the construction works and natural ground conditions. The AGF method is about the same as the pipe roof method with regard to the natural ground accepting mechanism and the materials used. The difference is building an improved body in a limited area in the natural ground around the steel pipes by injecting the fixing material. The use of this method caused no problems in subsidence and displacement in the surrounding ground, and completed the tunneling construction without an unusual event. 1 ref., 7 figs., 2 tabs.

Tuononen, T; Lammintakanen, J; Suominen, A L

2017-12-01

The aim was to study factors associated with staying in a dentist leadership position. We used an electronic questionnaire to gather data from 156 current or former Finnish dentist leaders in 2014. Principal component analysis categorized statements regarding time usage and opportunities in managerial work into five main components. Associations between these main component scores and the tendency to stay as a leader were analyzed with logistic regression. Out of the five main components, two were significantly associated with staying as a leader: 'career intentions', which represented intent to continue or to leave the leadership position; and 'work time control opportunities', which represented how leaders could control their own work time. Other factors that supported staying were leadership education, more work time available for leadership work, and lower age. The main component 'work pressure' decreased, although not significantly, the odds of continuing; it included lack of leadership work time, and pressure from superiors or subordinates. Leaders have important roles in health care, ensuring everyday operations as well as developing their organizations to meet future challenges. Knowledge of these supporting factors will enable dentist leaders and their organizations to improve working conditions in order to recruit and retain motivated and competent persons. In addition, well-designed education is important to inspire and encourage future leaders. Copyright© 2017 Dennis Barber Ltd.

2018-01-01

In order to improve the capability of particle trapping close to the source plane, theoretical and experimental studies on near-field multiple traps of paraxial acoustic vortices (AVs) with a strengthened acoustic gradient force (AGF) generated by a sector transducer array were conducted. By applying the integration of point source radiation, numerical simulations for the acoustic fields generated by the sector transducer array were conducted and compared with those produced by the circular transducer array. It was proved that strengthened AGFs of near-field multiple AVs with higher peak pressures and smaller vortex radii could be produced by the sector transducer array with a small topological charge. The axial distributions of the equivalent potential gradient indicated that the AGFs of paraxial AVs in the near field were much higher than those in the far field, and the distances at the near-field vortex antinodes were also proved to be the ideal trapping positions with relatively higher AGFs. With the established 8-channel AV generation system, theoretical studies were also verified by the experimental measurements of pressure and phase for AVs with various topological charges. The formation of near-field multiple paraxial AVs was verified by the cross-sectional circular pressure distributions with perfect phase spirals around central pressure nulls, and was also proved by the vortex nodes and antinodes along the center axis. The favorable results demonstrated the feasibility of generating near-field multiple traps of paraxial AVs with strengthened AGF using the sector transducer array, and suggested the potential applications of close-range particle trapping in biomedical engineering.

Full Text Available Purpose. The engineering industry is characterized by deep specialization and high co-operation, which suggests a high degree of interaction with other industries and the economy, highly sensitive to external factors. Effective regulation of the engineering industry’s organizational-resource support will ensure coherence of all the subsystems of the market economy, the competitive environment, a full course of the investment process and the success of the industry. Therefore there is a need for detailed estimation and analysis of the external factors’ influence on the formation and implementation indexes of the engineering industry’s organizational-resource support. Methodology. To establish the close connection between the set of external factors of formation and implementation indexes of the engineering industry organizational-resource support the correlation analysis was used, to calculate the amount of the formation and implementation indexes of the engineering industry organizational-resource support’s change under the influence of the external factors with malleability coefficient were applied.

This article explores the challenges, support needs and coping strategies of caregivers of people with an acquired brain injury (ABI). Semi-structured interviews were conducted with caregivers (n = 20) to explore their support services received, access barriers, utility of services, needed supports, coping strategies and factors promoting life satisfaction. The team recorded, transcribed verbatim and inductively analysed all interviews. Through thematic data analysis, three central themes were revealed: (a) barriers impeding quality-of-life, (b) support needed to improve quality-of-life and (c) factors enabling quality-of-life. All perspectives from the participants involved are synthesized to provide a rich depiction of caregivers' support needs and coping strategies. Two specific findings of interest include a negative association between severity of brain injury and caregiver's desire to direct treatment, as well as a distinct service gap in assistance for caregivers who are caring for someone with violent/offending behaviours. This study recommends short- and long-term changes, given Australia's upcoming National Disability Insurance Scheme, to increase caregiver quality-of-life, which will ultimately affect the rehabilitation outcomes of persons with ABI.

Despite the huge body of research on social support, literature has been primarily focused on its beneficial role for both physical and mental health. It is still unclear why people with mental and neurological disorders experience low levels of social support. The main objective of this study was to explore what are the strongest factors related to social support and how do they interact with each other in neuropsychiatric disorders. The study used cross-sectional data from 722 persons suffering from dementia, depression, epilepsy, migraine, multiple sclerosis, Parkinson's disease, schizophrenia, stroke, and substance use disorders. Multiple linear regressions showed that disability was the strongest factor for social support. Extraversion and agreeableness were significant personality variables, but when the interaction terms between personality traits and disability were included, disability remained the only significant variable. Moreover, level of disability mediated the relationship between personality (extraversion and agreeableness) and level of social support. Moderation analysis revealed that people that had mental disorders experienced lower levels of support when being highly disabled compared to people with neurological disorders. Unlike previous literature, focused on increasing social support as the origin of improving disability, this study suggested that interventions improving day-to-day functioning or maladaptive personality styles might also have an effect on the way people perceive social support. Future longitudinal research, however, is warranted to explore causality. PMID:26900847

Full Text Available In recent years, information technology (IT becomes prominent to support teaching and learning activities. IT tools allow us to create, collect, store and use the information and knowledge. E-learning was one of IT tools introduced at College of Science and Technology (CST, University Technology Malaysia (UTM Kuala Lumpur since 2001. It has enabled a paradigm shift from institutio n-centered instruction to anywhere, anytime and anybody learning models. In CST the e-learning technology was used for accessing the syllabus and course content, submitting assignments, and taking class quizzes. This paper focuses on issues relating to the e-learning critical success factors (CSFs from university students’ perspective. In this study, two main factors related to the e-learning CSFs within a university environment included technological and institutional support factors were examined. Confirmatory factor modeling approach was used to assess the criticality of the measures included in each factor. The results indicated that the most critical measures for technological factor in terms of ease of access and infrastructure are the browser efficiency, course website ease of use and computer network reliability. Meanwhile, for institutional support factor, the most critical measure is the availability of technical support or help desk.

Following professional standards is the main concern of all managers in organizations. The functions of nurses are essential for both productivity and improving health organizations. In human resources management, supporting nursing profession is of ultimate importance. However, nurses' experiences of perceived support, which are affected by various factors in workplace, have not been clearly explained yet. Thus, this study aimed to explain nurses' experiences of perceived support and their contributing factors. This study is a qualitative research in which 12 nurses were selected through purposive sampling among nurses in university hospitals affiliated to University of Medical Sciences, Urmia, Iran, during 2011-2012. Data collection was conducted through deep interviews with semi-structural questions. All interviews were first recorded and then transcribed. Finally, data were analyzed through conventional content analysis. The four main themes indicated that nurses experienced their workplace as non-supportive. Themes such as poor organizational climate, low social dignity, poor work conditions, and managers' ignorance to individual and professional values were considered as inhibitory factors to support. Nursing managers can promote nurses' positive support perceptions through recognizing inhibitory factors and applying fair solutions and take benefits of their positive consequences including high efficacy, self-esteem, and organizational commitment to promote the quality of care.

Full Text Available This study investigated the extent to which perceived social support functioned as a protective factors, and dimensions of insecure attachment (i.e., avoidant and anxious functioned as risks factors for physical and psychological health. We explored whether insecure attachment was a mechanism that modified the relationship (i.e., protect against or increases risk between social support and adult health. Participants were 155 non-traditional adult college students from demographically diverse backgrounds. Students were approached in common areas on campus or in classrooms during break and were asked to complete the questionnaire. Bartholomew and Horowitz’s Attachment Questionnaire assessed avoidant and anxious attachment dimensions, the Brief Social Support Questionnaire assessed perceived social support, and the Memorial Symptom Assessment Scale measured physical and psychological symptoms. Model results indicated that the anxious dimension of insecure attachment was more directly and positively associated with poorer general physical health and psychological symptoms, whereas greater perceived social support was linked with better reported health. However, an interesting pattern emerged with avoidant attachment through a moderated relationship with social support. The absence of a satisfying supportive network was significantly related to poorer physical and psychological health outcomes for those low in avoidant attachment, but not for those high in avoidant attachment. Results from this work suggest that insecure attachment plays a detrimental role in adult health. Perceived social support does not necessarily function as a blanket protective factor for health, as it seemed to offer less benefit to those high in attachment avoidance.

Full Text Available Objectives: To investigate community support for government-led policy initiatives to positively influence the food environment, and to identify whether there is a relationship between support for food policy initiatives and awareness of the link between obesity-related lifestyle risk factors and cancer. Methods: An online survey of knowledge of cancer risk factors and attitudes to policy initiatives that influence the food environment was completed by 2474 adults from New South Wales, Australia. The proportion of participants in support of seven food policy initiatives was quantified in relation to awareness of the link between obesity, poor diet, insufficient fruit and vegetable consumption, and physical inactivity with cancer and other health conditions. Results: Overall, policies that involved taxing unhealthy foods received the least support (41.5%. Support was highest for introducing a colour-coded food labelling system (85.9%, restricting claims being made about the health benefits of foods which are, overall, unhealthy (82.6%, displaying health warning labels on unhealthy foods (78.7% and banning unhealthy food advertising that targets children (72.6%. Participants who were aware that obesity-related lifestyle factors are related to cancer were significantly more likely to support food policy initiatives than those who were unaware. Only 17.5% of participants were aware that obesity, poor diet, insufficient fruit and vegetable consumption, and physical inactivity are linked to cancer. Conclusions: There is strong support for all policies related to food labelling and a policy banning unhealthy food advertising to children. Support for food policy initiatives that positively influence the food environment was higher among those who were aware of the link between cancer and obesity-related lifestyle factors than among those who were unaware of this link. Increasing awareness of the link between obesity-related lifestyle factors and cancer

The purpose of the current study was to examine the factor structure and measurement invariance of a scale measuring students' perceptions of need-supportive teaching (Need-Supportive Teaching Style Scale in Physical Education; NSTSSPE). We sampled 615 secondary school students in Hong Kong, 200 of whom also completed a follow-up assessment two months later. Factor structure of the scale was examined through exploratory structural equation modeling (ESEM). Further, nomological validity of the NSTSSPE was evaluated by examining the relationships between need-supportive teaching style and student satisfaction of psychological needs. Finally, four measurement models-configural, metric invariance, scalar invariance, and item uniqueness invariance-were assessed using multiple group ESEM to test the measurement invariance of the scale across gender, grade, and time. ESEM results suggested a three-factor structure of the NSTSSPE. Nomological validity was supported, and weak, strong, and strict measurement invariance of the NSTSSPE was evidenced across gender, grade, and time. The current study provides initial psychometric support for the NSTSSPE to assess student perceptions of teachers' need-supportive teaching style in physical education classes.

Support groups fill a critical void in the health care system, harnessing the power of shared experiences to provide support to group members. Likewise, family caregivers fill a void in the health care system, providing billions in unpaid care to the chronically ill. Caregiver support groups offer an opportunity for alleviating the psychological burden of caregiving. The power of any group, including a support group, to foster psychological well-being lies in its ability to cultivate Yalom's therapeutic factors. Gaps in the literature remain regarding the ability of non-prototypical groups to promote therapeutic mechanisms of change. The purpose of this study was to determine if and when Yalom's therapeutic group factors emerged in a peer-led support group delivered in an asynchronous, online format. Qualitative content analysis utilizing deductive category application was employed. Participants' responses were coded and frequency counts were conducted. Results revealed that 9 of 11 therapeutic factors emerged over the course of the group, with Group Cohesiveness, Catharsis, Imparting of Information, and Universality occurring most often. Several factors, including Interpersonal Learning, Corrective Recapitulation of the Primary Family Group, Imitative Behavior, and Development of Socializing Techniques were absent or virtually absent, likely due to the peer-led format of the group. Progression of therapeutic factors over the course of the group is presented. Findings demonstrate the presence of a variety of Yalom's therapeutic factors in an asynchronous, peer-led online support group.

Full Text Available The factors that directly influence the formation of a sealing clearance between the piston and the working cylinder in hydraulic legs of powered supports are considered in this article, the size thereof has a direct effect on the tightness of the legs and, as a result, on the safety of work at the production face. A detailed description of these factors is given, which is supported by the dependencies obtained from the results of finite element modeling of various types of legs under various strength and geometric parameters, external load types and locations in the support section. The problems of formation of radial deformations of a working cylinder loaded with working fluid pressure are considered, and their dependence on the level of this pressure and extension. Based on the simulation results, the mechanisms for the formation of additional clearances due to rod and cylinder misalignments are described, and the conditions and causes of the resonant phenomena development are given. The classification of these factors according to the degree of generalization and the functional interaction between each other is proposed.

Seismic damping tests of a prototypical Liquid Metal Fast Breeder Reactor (LMFBR) small bore piping system is described, and measured transient responses to pulse excitations are reported. The test specimen was representative of a typical LMFBR insulated small bore piping system, and it was supported from a rigid test frame by prototypic dead weight supports, mechanical snubbers, and pipe clamps. Various support configurations were tested to assess the response sensitivity to insulation and other nonlinear support characteristics. Damping factors increased significantly due to the insulation and use of mechanical snubbers. Factors much higher than the magnitudes currently allowed in design by the USNRC Regulatory Guide 1.61, were found. This verified the design values, and it also pointed out the possibility of undue conservatism and costly overdesign resulting from use of the present design values

Background: This study aims to explore how sufficient social support can act as a possible preventive factor against fighting and bullying in school-aged children in 9 European countries. Methods : Data for this study were collected during the 2013/2014 Health Behaviour in School-aged Children (HBSC) survey. The sample consisted of 9 European countries, involving 43,667 school children in total, aged 11, 13 and 15 years. The analysed data focus on social context (relations with family, peers, and school) as well as risk behaviours such as smoking, drunkenness, fighting and bullying in adolescents. The relationships between social support and violent behaviour variables were estimated using multiple regression models and multivariate analyses. Results : Bullying, across 9 countries, was more prevalent than fighting, except for Armenia, Israel, and Poland. The prevalence among countries differed considerably, with fighting being most expressed in Armenia and bullying—in Latvia and Lithuania. The strongest risk factors for bullying and fighting were male gender (less expressed for bullying), smoking and alcohol consumption. In addition, for bullying the social support was similarly strong factor like above-mentioned factors, while for fighting—less significant, but still independent. All forms of social support were significantly relate with lower violent behaviour of school children, and family support was associated most strongly. Regardless the socioeconomic, historical, and cultural differences among selected countries, the enhancement and reinforcement of the social support from possible many different resources should be taken into consideration in prevention programs against school violence behaviours.

Full Text Available Many studies have been done to identify the critical success factors (CSFs in for successful lean implementation in the manufacturing firms. But, till date, no systematic study has been done to identify the CSFs from the perspective of lean implementation in IT support service sector. This paper aims to address this area. A detailed literature review was undertaken to identify CSFs for lean implementation in manufacturing and services context and to consider their applicability to the IT support services sector. This paper is based on a conceptual discussion of CSFs as applied to the IT support services sector. The authors proposed a set of CSFs which is believed to be suitable for IT support service enterpri ses. The relevance of CSFs will need to be tested and qualitative research is needed to inform further work. The proposed CSFs are aimed at being useful to IT support services sector as a guideline, so as to ensure a positive outcome of the lean implementation process in IT support services sector.

The project's objectives are the evaluation of the reliability concerning the identification of Human Factors as contributing factors by a computer supported event analysis (CEA). CEA is a computer version of SOL (Safety through Organizational Learning). Parts of the first step were interviews with experts from the nuclear power industry and the evaluation of existing computer supported event analysis methods. This information was combined to a requirement profile for the CEA software. The next step contained the implementation of the software in an iterative process of evaluation. The completion of this project was the testing of the CEA software. As a result the testing demonstrated that it is possible to identify contributing factors with CEA validly. In addition, CEA received a very positive feedback from the experts. (orig.) [de

To examine terrorism survivors' perceptions of factors likely to promote coping and recovery, and to determine whether coping supports vary according to demographic, physical and mental health, incident-exposure and bereavement variables. Individuals directly exposed to and/or bereaved by the 2002 Bali bombings and who had participated in a New South Wales Health therapeutic support program completed cross-sectional telephone interviews during July-November 2010. Spoken passages were categorised into coping support themes. Advocated supports were then examined by demographic, physical and mental health, incident-exposure and bereavement variables. Based on their experiences, respondents identified personal, social and service-related factors that they believed would optimally support future survivors of terrorism. Of the 81 people contacted, 55 (68%) participated, providing a total of 114 comments. Thirty-two respondents were women, and 54 had lost relatives or friends in the bombing. Mean age was 50 years (range, 20-73 years). Four meaningful coping support themes emerged, with excellent inter-rater reliability: professional help and counselling; social support; proactive government response and policy; and personal coping strategies. Women were significantly more likely to advocate the need for proactive government response (P = 0.03). Men were more likely to endorse the use of personal coping strategies (P terrorism-affected groups. Male survivors may benefit more from mental health interventions that initially build on problem-focused forms of coping, including brief education about reactions and periodic check-ups. Proactive government health and support services that allow simplified and longer-term access were consistently identified as priority areas.

Full Text Available The study on contextual factors in Malaysian family is more concentrated among mothers compared to the fathers. Malaysian fathers are often influenced by these factors embedded in the family. This study examines the level of contextual factors among fathers of adolescent children. The survey was conducted using a simple sampling method, on a group of 413 fathers with adolescent children from all districts in the state of Selangor, West Peninsular of Malaysia. A set of questionnaires was used to derive data from the fathers̕ contextual factors which are marriage satisfaction, family support and work-family conflict among fathers of adolescents. Analysis on frequency, percentage, mean, standard deviation, t-test, analysis of Variance (ANOVA and the Pearson correlations were used to investigate the level and correlation of contextual factors among fathers of adolescent children. The Pearson correlation shows that there is a significant correlation between work-family conflict and marriage satisfaction and between family support and marriage satisfaction. However, there is no significant correlation between family support and work-family conflict. The study proficiently contributes towards the exploration of influencing factors for the involvement of fathers in parenting.

Expanding condom-related knowledge and skills and reducing barriers to condom use have the potential to help reduce pregnancies and sexually transmitted infections among youth. These goals are sometimes addressed through condom education and availability (CEA) programs as part of sexuality education in school. Parents are a key constituency in efforts to implement such programs. A representative statewide sample of households with children (N = 1,093) in California was employed to examine parent support for CEA and the potential influences of demographics (gender, age, and Hispanic ethnicity), sociodemographics (education, religious affiliation, religious service attendance, and political ideology), and condom-related beliefs (belief in condom effectiveness and belief that teens who use condoms during sex are being responsible) on parent support for CEA. The parents in our sample reported a high level of support for CEA (M = 3.23 on a 4-point scale) and believing in a high level of condom effectiveness (M = 3.36 on a 4-point scale). In addition, 84% of the parents agreed that teens who use condoms during sex are being responsible. Hierarchical regression analyses showed that parents who were younger, Hispanic, with a lower educational attainment, without a religious affiliation, less religiously observant, and politically liberal were more supportive of CEA. After controlling for these demographic and sociodemographic factors, condom effectiveness and responsibility beliefs each added independently to the predictability of parent support for CEA. These findings suggest that parent education related to condom effectiveness could help increase support for school-based CEA programs.

Across-site patterns of electrically evoked compound action potential amplitude-growth functions in multichannel cochlear implant recipients and the effects of the interphase gap.

Schvartz-Leyzac, Kara C; Pfingst, Bryan E

2016-11-01

Electrically evoked compound action potential (ECAP) measures of peak amplitude, and amplitude-growth function (AGF) slope have been shown to reflect characteristics of cochlear health (primarily spiral ganglion density) in anesthetized cochlear-implanted guinea pigs. Likewise, the effect of increasing the interphase gap (IPG) in each of these measures also reflects SGN density in the implanted guinea pig. Based on these findings, we hypothesize that suprathreshold ECAP measures, and also how they change as the IPG is increased, have the potential to be clinically applicable in human subjects. However, further work is first needed in order to determine the characteristics of these measures in humans who use cochlear implants. The current study examined across-site patterns of suprathreshold ECAP measures in 10 bilaterally-implanted, adult cochlear implant users. Results showed that both peak amplitude and slope of the AGF varied significantly from electrode to electrode in ear-specific patterns across the subjects' electrode arrays. As expected, increasing the IPG on average increased the peak amplitude and slope. Across ears, there was a significant, negative correlation between the slope of the ECAP AGF and the duration of hearing loss. Across-site patterns of ECAP peak amplitude and AGF slopes were also compared with common ground impedance values and significant correlations were observed in some cases, depending on the subject and condition. The results of this study, coupled with previous studies in animals, suggest that it is feasible to measure the change in suprathreshold ECAP measures as the IPG increases on most electrodes. Further work is needed to investigate the relationship between these measures and cochlear implant outcomes, and determine how these measures might be used when programming a cochlear-implant processor.

Mandatory smoke-free policies in subsidized, multiunit housing (MUH) may decrease secondhand smoke exposure in households with the highest rates of exposure. Ideally, policies should be based on a strong understanding of factors affecting support for smoke-free policies in the target population to maximize effectiveness. A face-to-face survey was conducted from August to October 2011 using a stratified random sample of private subsidized housing units in Columbus, OH, without an existing smoke-free policy (n = 301, 64% response rate). Lease holders were asked to report individual, social, and environmental factors hypothesized to be related to support for smoke-free policies. Multiple logistic regression models were used to identify factors independently associated with policy support. Most tenants supported smoke-free policies in common areas (82.7%), half supported policies inside units (54.5%), and one third supported a ban outside the building (36.3%). Support for smoke-free policies in units and outdoors was more common among nonsmokers than smokers (71.5% vs. 35.7%, p social, but no environmental, factors were independently associated with policy support. Smokers who intended to quit within 6 months or less were more likely than other smokers to support in-unit policies (45.3% vs. 21.1%; p = .003). More than half of subsidized MUH tenants supported smoke-free policies inside their units. Strategies to address individual- and social-level barriers to behavior change should be implemented in parallel with smoke-free policies. Policies should be evaluated with objective measures to determine their effectiveness.

Environmental and personal factors that support early return-to-work: a qualitative study using the ICF as a framework.

2014-01-01

Occupational health professionals such as occupational physicians (OPs) increasingly understand that in addition to health improvement, environmental factors (such as work adaptations) and personal factors (such as an employee's attitude towards return-to-work (RTW)) may stimulate employees on sick leave to return to work early. To target their professional interventions more specifically according to these factors, occupational health professionals need further insight into environmental and personal factors that stimulate RTW. The objectives of this study are (1) to identify which and how environmental and personal factors support RTW, and (2) to examine whether the International Classification of Functioning, Disability and Health (ICF) can be used to describe these factors. We performed interviews with 14 employees, 15 employers and 4 OPs from multiple organisations with varying organisational sizes and types of industry such as healthcare and education. We used a qualitative data analysis partially based on the Qualitative Analysis Guide of Leuven. The following environmental factors were found to support early RTW: 'social support from relatives', 'belief that work stimulates health', 'adequate cooperation between stakeholders in RTW' (e.g., employees, employers and OPs) and 'the employers' communicative skills'. One personal factor stimulated RTW: 'positive perception of the working situation' (e.g. enjoyment of work). Most factors stimulated RTW directly. In addition, adequate treatment and social support stimulated medical recovery. Environmental factors can either fully (social support, belief that RTW stimulates health), partially (effective cooperation), or not (employers' communicative skills) be described using ICF codes. The personal factor could not be classified because the ICF does not contain codes for personal factors. RTW interventions should aim at the environmental and personal factors mentioned above. Professionals can use the ICF to

The purpose of this article is to expand the understanding of self-management support by describing factors that contribute to implementing a comprehensive self-management program in primary care. Four rural health centers in medically underserved areas participated in a study to document the implementation of a self-management program. This program consisted of a social marketing plan and decision-making tools to guide patients in making self-management behavior changes. The stages of change constructs of the transtheoretical model were used to design the social marketing plan. Key informant interviews were conducted at 6-month and 9-month intervals to document the implementation process. A standardized set of questions was used in the interviews. The data from the interviews were analyzed using content analysis techniques. One of the principle findings is that self-management support requires putting a system in place, not just adding a new component to primary care. The health centers that fully implemented the self-management program made an organizational commitment to keep self-management on the agenda in management meetings, clinical staff set the example by adopting self-management behaviors, and patient self-management support was implemented in multiple patient care venues. Primary care centers with limited financial resources are able to integrate self-management support into their system of chronic illness care.

Full Text Available The Support System in Distance Education:Factors Affecting Achievements Among Women Learners Hanafi ATAN Zuraidah A. RAHMAN Omar MAJID Noraida A. GHANIRozhan M IDRUS School of Distance EducationUniversiti Sains Malaysia11800 Penang, MALAYSIA ABSTRACT Distance education has the potential to contribute to the enhancement of women’s development by overcoming not only temporal and spatial barriers but familial commitments as well. It brings education to their home and allows women to learn at their individual pace, seek skills for individual development and at the same time, enables them to fulfill family responsibilities. An important element of distance education is the provision of the learner support system that provides students the access to learning resources and means of communication that would facilitate the array of educational activities and exposure to various other guidance and advisories. This paper reports on the study undertaken to elucidate the dimensions of the support system provided by the School of Distance Education (SDE, Universiti Sains Malaysia (USM to its women learners that would have significant impact on their achievements. The factorial analysis conducted revealed that the role of the faculty is the main contributing factor affecting these achievements, followed by the provision of the intensive course, the electronic portal, video conferencing and to a much lesser extent, the existence of the regional centres. The implications of this study are discussed with the view of improving the support system provided by the institution and the need to put into action the necessary strategies to further improve the achievement of the women learners.

To elucidate the impact of social support and its interrelations with other demand-control-support (DCS) model factors on presenteeism and absenteeism, and to determine which DCS factors were most influential. Questionnaires from 2535 local government employees were analyzed. The Brief Job Stress Questionnaire (BJSQ) was used to assess DCS factors including job demand, job control, and social support from supervisors and coworkers. The Stanford Presenteeism Scale 13-item version (SPS-13) was used to evaluate both absenteeism (absent days) and presenteeism. For the latter, the Work Impairment Score (WIS) and the Work Output Score (WOS) were also used. Possible confounder-adjusted logistic and negative binomial regression analyses were performed to obtain odds ratios (ORs) for WIS and WOS and relative risks (RRs) for absenteeism according to DCS factors. Higher job control had a significantly protective effect on higher WIS in both males and females and a lower WOS in males. Based on a point estimate of an OR per 1 standard deviation change of each DCS factor, job control had the strongest effect on higher WIS in both males and females and a lower WOS in males. Higher job demand resulted in significantly higher ORs for both male and female WIS, and a lower WOS in females. Support from supervisors had a significantly protective effect on higher WIS in females and a lower WOS in males. Support from coworkers had a significantly protective effect on higher WIS in males. Higher support from coworkers had a significantly protective effect on absenteeism among both males and females, and higher job control had a significantly protective effect in females. The combination of high job strain and low support from supervisors had a significantly worsening effect, except for absenteeism in females. High job strain and low support from coworkers had a significantly worsening effect except for WOS in males. The results suggest job control was the DCS factor most related to

Full Text Available Pär I Johansson, Sisse R OstrowskiCapital Region Blood Bank, Section for Transfusion Medicine, Rigshospitalet, University of Copenhagen, Copenhagen, DenmarkBackground: Recombinant activated factor VII (rFVIIa, NovoSeven® was introduced in 1996 for the treatment of hemophilic patients with antibodies against coagulation factor VIII or IX.Objective: To review the evidence supporting the use of rFVIIa for the treatment of patients with congenital bleeding disorders.Patients and methods: English-language databases were searched in September 2009 for reports of randomized controlled trials (RCTs evaluating the ability of rFVIIa to restore hemostasis in patients with congenital bleeding disorders.Results: Eight RCTs involving 256 hemophilic patients with antibodies against coagulation factors, also known as inhibitors, were identified. The evidence supporting the use of rFVIIa in these patients was weak with regard to dose, clinical setting, mode of administration, efficacy, and adverse events, given the limited sample size of each RCT and the heterogeneity of the studies.Conclusion: The authors suggest that rFVIIa therapy in hemophilic patients with inhibitors should be based on the individual’s ability to generate thrombin and form a clot, and not on the patient’s weight alone. Therefore, assays for thrombin generation, such as whole-blood thromboelastography, have the potential to significantly improve the treatment of these patients.Keywords: hemophilia, inhibitors, coagulation factor VIII, coagulation factor IX, rFVIIa, NovoSeven, FEIBA, hemostasis, RCT

To describe perceived social support among patients with coronary heart disease following percutaneous coronary intervention. A low level of social support is considered a risk factor for coronary heart disease in healthy individuals and reduces the likelihood that people diagnosed with coronary heart disease will have a good prognosis. A descriptive cross-sectional study. A survey of 416 patients was conducted in 2013. A self-report instrument, Social Support of People with Coronary Heart Disease, was used. The instrument comprises three dimensions of social support: informational, emotional, functional supports and 16 background variables. Data were analysed using descriptive statistics, factor analysis, mean sum variables and multivariate logistic regression. Perceived informational support was primarily high, but respondents' risk factors were not at the target level. The weakest items of informational support were advice on physical activity, continuum of care and rehabilitation. Regarding the items of emotional support, support from other cardiac patients was the weakest. The weakest item of functional support was respondents' sense of the healthcare professionals' care of patients coping with their disease. Background variables associated with perceived social support were gender, marital status, level of formal education, profession, physical activity, duration of coronary heart disease and previous myocardial infarction. Healthcare professionals should pay extra attention to women, single patients, physically inactive patients, those demonstrating a lower level of education, those with a longer duration of CHD, and respondents without previous acute myocardial infarction. Continuum of care and counselling are important to ensure especially among them. This study provides evidence that healthcare professionals should be more aware of the individual needs for social support among patients with coronary heart disease after percutaneous coronary intervention

Chronic conditions put a heavy burden on healthcare in every country. Supporting persons with a chronic illness to take an active role in the management of their condition is a core component in the Chronic Care Model. It implies confidence and good skills from professionals. To date, there is no evidence on final year nursing students' performance in supporting patients' self-management, nor on factors associated with this performance. To explore self-reported performance of supporting patients' self-management by final year nursing students, and person-related factors associated with this performance. A correlational multi-centre study of final year nursing students (N=256) from eight nursing schools. Students were recruited from a convenience sample of eight nursing schools. All final year students were invited to participate. Data were collected between January 2015 and May 2016 using self-administered validated questionnaires. Theoretical behavioural frameworks were used to select hypothesized associated factors for self-management support: self-efficacy to perform self-management support and socio-structural factors (Social Cognitive Theory); needs for autonomy, competence and relatedness, and patient-invested contingent self-esteem (Self-Determination Theory); and attitudes towards supporting patients' self-management (Theory of Planned Behaviour). Final year nursing students (N=256) reported an overall low level of performance in delivering self-management support during internship. Students lacked mainly competencies in collaborative goal setting and shared decision making. Students reported a significant gap between their confidence and their actual performance in self-management support (pLearning opportunities can be introduced in classroom activities and on internship.

Influencing factors of public support for modern coal-fired power plant projects: An empirical study from China

International Nuclear Information System (INIS)

Liu, Feng; Lyu, Tao; Pan, Li; Wang, Fei

2017-01-01

With the development of clean coal technology, modern coal-fired power plants have achieved the similar emission standards as gas power plants. However, due to the impressions of high pollution and high emission in traditional coal-fired power plants, such projects are often opposed by local residents, which hinder the promotion of this technology. This manuscript aims to investigate public attitudes toward these projects and to analyze the influencing mechanisms of the factors of public support. The conceptual model was built with sense of place, trust and environmental attitude as the independent variables, benefit and cost perceptions as the mediating variables and public support as the dependent variable. The model was tested and modified by structural equation modelling. The results revealed that sense of place had a slight indirect impact (−0.043) on public support through benefit perception, whereas trust had a direct impact (0.332) on public support and indirect impacts (0.298) through benefit and cost perceptions. Environmental attitude had indirect impacts on public support through benefit perception (0.180) and cost perception (−0.115). In addition, policy suggestions on decision-making, project publicity and compensation strategy are proposed to enhance public support for similar projects. - Highlights: • This manuscript aims at eliminating the NIMBY effects on modern coal-fired power plant project. • A SEM model is proposed to explore how potential factors affect public support. • Trust is the dominant influencing factor to improve public support with both direct and indirect impacts. • Environmental attitude can also have positive effect on public support through rational compensation plans.

Immune suppressor factor (ISF) is a subunit of the vacuolar ATPase proton pump. We earlier identified a short form of ISF (ShIF) as a stroma-derived factor that supports cytokine-independent growth of mutant Ba/F3 cells. Here, we report that ISF/ShIF supports self-renewal and expansion of primary hematopoietic stem cells (HSCs). Co-culture of murine bone marrow cells with a stromal cell line overexpressing ISF or ShIF (MS10/ISF or MS10/ShIF) not only enhanced their colony-forming activity and the numbers of long-term culture initiating cells, but also maintained the competitive repopulating activity of HSC. This stem cell supporting activity depended on the proton-transfer function of ISF/ShIF. Gene expression analysis of ISF/ShIF-transfected cell lines revealed down-regulation of secreted frizzled-related protein-1 and tissue inhibitor of metalloproteinase-3, and the restoration of their expressions in MS10/ISF cells partially reversed its enhanced LTC-IC supporting activity to a normal level. These results suggest that ISF/ShIF confers stromal cells with enhanced supporting activities for HSCs by modulating Wnt-activity and the extracellular matrix

Sequential bilingual children in the United States often speak 2 languages that have different social statuses (minority-majority) and separate contexts for learning (home-school). Thus, distinct factors may support the development of each language. This study examined which child internal and external factors were related to vocabulary skills in a minority language versus English. Participants included 69 children, aged 5-8 years, who lived in Southern California, spoke Vietnamese as the home language, and received school instruction in English. All participants had at least 1 foreign-born parent, and most mothers reported limited English proficiency. Parents completed a telephone survey, and children completed measures of receptive and expressive vocabulary in each language. Using correlations and stepwise regression, we examined predictors of vocabulary skills in each language that were internal to the child (age, gender, analytical reasoning, phonological memory) or that pertained to the surrounding environment (cumulative exposure, quantity and quality of input/output). Vietnamese vocabulary outcomes were related to multiple external factors, of which input and enrichment activities were the best predictors. In contrast, English vocabulary outcomes were related to internal factors, of which age and phonological memory were the best predictors. Parental use of Vietnamese contributed to children's Vietnamese vocabulary outcomes but was not related to children's English vocabulary outcomes. Vietnamese exposure does not hinder English development. Children from immigrant families are learning English with or without familial support. Rich and frequent exposure and opportunities for practice are essential for the continued development of a minority first language.

The association of socioeconomic factors, health-related factors, and social support with depressive symptoms has been extensively studied. However, most epidemiological studies have focused on a few factors such as marital status, social class, and employment. In this study of middle-aged women we...... analyzed both univariate and multivariate associations of socioeconomic factors, perceived physical health factors, and social support with self-rated depressive symptoms measured with the Beck Depression Inventory. A nationwide sample (n = 1851) of Finnish women aged 48-50 years was analyzed....... Socioeconomic, health-related, and social support factors were all measured with single items. All variables, except level of urbanization, were significantly associated with depressive symptoms in univariate analyses. Multivariate associations were examined with standard multiple regression analyses in three...

There is global interest in recovering locally extirpated carnivore species. Successful efforts to recover Louisiana black bear in Louisiana have prompted interest in recovery throughout the species’ historical range. We evaluated support for three potential black bear recovery strategies prior to public release of a black bear conservation and management plan for eastern Texas, United States. Data were collected from 1,006 residents living in proximity to potential recovery locations, particularly Big Thicket National Preserve. In addition to traditional logistic regression analysis, we used conditional probability analysis to statistically and visually evaluate probabilities of public support for potential black bear recovery strategies based on socioeconomic characteristics. Allowing black bears to repopulate the region on their own (i.e., without active reintroduction) was the recovery strategy with the greatest probability of acceptance. Recovery strategy acceptance was influenced by many socioeconomic factors. Older and long-time local residents were most likely to want to exclude black bears from the area. Concern about the problems that black bears may cause was the only variable significantly related to support or non-support across all strategies. Lack of personal knowledge about black bears was the most frequent reason for uncertainty about preferred strategy. In order to reduce local uncertainty about possible recovery strategies, we suggest that wildlife managers focus outreach efforts on providing local residents with general information about black bears, as well as information pertinent to minimizing the potential for human-black bear conflict.

Trontl, Kresimir; Smuc, Tomislav; Pevec, Dubravko

2007-01-01

The accuracy of the point-kernel method, which is a widely used practical tool for γ-ray shielding calculations, strongly depends on the quality and accuracy of buildup factors used in the calculations. Although, buildup factors for single-layer shields comprised of a single material are well known, calculation of buildup factors for stratified shields, each layer comprised of different material or a combination of materials, represent a complex physical problem. Recently, a new compact mathematical model for multi-layer shield buildup factor representation has been suggested for embedding into point-kernel codes thus replacing traditionally generated complex mathematical expressions. The new regression model is based on support vector machines learning technique, which is an extension of Statistical Learning Theory. The paper gives complete description of the novel methodology with results pertaining to realistic engineering multi-layer shielding geometries. The results based on support vector regression machine learning confirm that this approach provides a framework for general, accurate and computationally acceptable multi-layer buildup factor model

Silver-mediated direct trifluoromethoxylation of α-diazo esters and ketosteroid was disclosed. The reactions of alkyl α-diazo arylacetates with AgOCF3 or CF3SO2OCF3/AgF at -30 to 10 °C under a N2 atmosphere provided α-trifluoromethoxyl arylacetates in up to 90% yield, while alkyl α-diazo vinylacetates reacting with CF3SO2OCF3/AgF or AgOCF3 afforded γ-trifluoromethoxyl α,β-unsaturated esters in up to 94% yield. The α-diazo ketosteroid was also trifluoromethoxylated under the standard reaction conditions. This protocol allows for an effective and convenient access to a large number of synthetic building blocks, which are promising in the development of new functional OCF3-molecules.

Objectives African American maternal caregiver support for prevention of childhood obesity may be a factor in implementing, monitoring, and sustaining children's positive health behaviors. However, little is known about how perceptions of childhood obesity risk factors and health complications influence caregivers' support of childhood obesity prevention strategies. The objective of this study was to determine if childhood obesity risk factors and health complications were associated with maternal caregivers' support for prevention initiatives. Methods A convenience sample of maternal caregivers (N = 129, ages 22-65 years) completed the childhood obesity perceptions (COP) survey. A linear regression was conducted to determine whether perceptions about childhood obesity risk factors and subsequent health complications influenced caregivers' support for prevention strategies. Results Caregivers' perceptions of childhood obesity risk factors were moderate (M = 3.4; SD = 0.64), as were their perceptions of obesity-related health complications (M = 3.3; SD = 0.75); however, they perceived a high level of support for prevention strategies (M = 4.2; SD = 0.74). In the regression model, only health complications were significantly associated with caregiver support (β = 0.348; p obesity prevention efforts should emphasize health complications by providing education and strategies that promote self-efficacy and outcome expectations among maternal caregivers.

2018-05-01

This study explores public interests associated with shellfish aquaculture development in coastal waters of Rhode Island (US). Specifically, we examine (1) the levels of public support for (or opposition to) shellfish aquaculture development and (2) factors driving the levels of support, using survey data and ordinal logistic regressions. Results of the analysis identify several key attitudinal factors affecting individual's support for shellfish aquaculture in Rhode Island (RI). The level of support is positively associated with attitudes related to shellfish aquaculture's benefits to the local economy and its role as a nutritional food option, and negatively influenced by attitudes related to aquaculture farms' effects on aesthetic quality and their interference with other uses. Findings highlight that support for (or opposition to) aquaculture in RI is driven more by attitudes associated with social impacts than by those associated with environmental impacts. The level of support is also affected by personal characteristics related to an individual's participation in recreational activities. For instance, bicycle riders tend to be supportive of shellfish aquaculture while respondents who participate in sailing and birding are less supportive. By identifying the broader public's interests in shellfish aquaculture, findings from this study and others like it can be used to address public concerns, incorporate public perceptions and attitudes into permitting decisions, and develop outreach targeted at specific stakeholder groups.

2005-01-01

As CRT-based display and advanced information technology were applied to advanced reactors such as APR-1400 (Advanced Power Reactor-1400), human operators' tasks became more cognitive works. As a results, Human Factors Engineering (HFE) became more important in designing the MCR (Main Control Room) MMI (Man-Machine Interface) of an advanced reactor. According to the Human Factors Engineering Program Review Model, human factors validation of MCR MMI design should be performed through performance-based tests to determine whether it acceptably supports safe operation of the plant. In order to support the evaluation of the performance, a HUman Performance Evaluation Support System (HUPESS) is in development

Photosynthetic cyanobacteria, heterotrophic bacteria, free-living amoebae, and ciliated protozoa may support growth of Legionella pneumophila. Studies were done with two tap water cultures (WS1 and WS2) containing L. pneumophila and associated microbiota to characterize growth-supporting activity and assess the relative importance of the microbiota in supporting multiplication of L. pneumophila. The water cultures were incubated in the dark at 35 degrees C. The growth-supporting factor(s) was separated from each culture by filtration through 1-micron-pore-size membrane filters. The retentate was then suspended in sterile tap water. Multiplication of L. pneumophila occurred when both the retentate suspension and the filtrate from either culture were inoculated into sterile tap water. L. pneumophila did not multiply in tap water inoculated with only the filtrate, even though filtration did not reduce the concentration of L. pneumophila or heterotrophic bacteria in either culture. Growth-supporting activity of the retentate suspension from WS1 was inactivated at 60 degrees C but unaffected at 0, 25, and 45 degrees C after 30-min incubations. Filtration experiments indicated that the growth-supporting factor(s) in WS1 was 2 to 5 micron in diameter. Ciliated protozoa were not detected in either culture. Hartmannellid amoebae were conclusively demonstrated in WS2 but not in WS1. L. pneumophila multiplied in tap water inoculated with the amoebae (10(3)/ml) and the 1-micron filtrate of WS2. No multiplication occurred in tap water inoculated with the filtrate only. Growth-supporting activity for L. pneumophila may be present in plumbing systems; hartmannellid amoebae appear to be important determinants of multiplication of L. pneumophila in some tap water cultures.

A distributed real-time simulation of the civil air traffic environment developed to support human factors research in advanced air transportation technology is presented. The distributed environment is based on a custom simulation architecture designed for simplicity and flexibility in human experiments. Standard Internet protocols are used to create the distributed environment, linking all advanced cockpit simulator, all Air Traffic Control simulator, and a pseudo-aircraft control and simulation management station. The pseudo-aircraft control station also functions as a scenario design tool for coordinating human factors experiments. This station incorporates a pseudo-pilot interface designed to reduce workload for human operators piloting multiple aircraft simultaneously in real time. The application of this distributed simulation facility to support a study of the effect of shared information (via air-ground datalink) on pilot/controller shared situation awareness and re-route negotiation is also presented.

2015-12-01

This 6-week longitudinal study aimed to examine a moderated mediation model that may explain the link between school-related social support (i.e., teacher support and classmate support) and optimal subjective well-being in school among adolescents (n = 1316). Analyses confirmed the hypothesized model that scholastic competence partially mediated the relations between school-related social support and subjective well-being in school, and social acceptance moderated the mediation process in the school-related social support--> subjective well-being in school path and in the scholastic competence--> subjective well-being in school path. The findings suggested that both social contextual factors (e.g., school-related social support) and self-system factors (e.g., scholastic competence and social acceptance) are crucial for adolescents' optimal subjective well-being in school. Limitations and practical applications of the study were discussed. Copyright © 2015 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd. All rights reserved.

Full Text Available The purpose of the present study was to investigate the related factors on work hope in University of Isfahan's Students. It was a descriptive, correlational study. The statistical samples of the study comprised of all of the students in the University of Isfahan in 2014-15. The sample including 300 students was selected through relatively stratified sampling in the University of Isfahan. The work hope scale, general self-efficacy questionnaire, differential status identity scale, time perspective questionnaires and perceived social support scale were used in collecting the data. The results of path analysis showed that family support indirectly related to work hope through social prestige and social power. Besides, family support indirectly related to self-efficacy through social power. Among the dimensions of perceived social status, social power was found to be indirectly related to work hope through self-efficacy, and social prestige found to be directly related to work hope. Further, self-efficacy was related to work hope both directly and indirectly. Among the aspects of time perspective, the present hedonistic was significantly and positively related to work hope; however, present fatalistic was significantly and negatively related to work hope. In general, the results showed that the self-efficacy, social prestige, social support, present hedonistic, present fatalistic and family support could predict work hope.

Ceglie, Robert

2013-02-01

This study explores the influence of religion as a support factor for a group of Latina and African-American women majoring in science. The current project is a part of a larger study that investigated persistence factors of underrepresented woman who were enrolled as science majors at United States colleges and universities. This paper focuses on one theme that emerged among six participants who disclosed how religion was a significant influence on their persistence in science fields. The strength and support offered by religious values is certainly not specific to science content; however, the support received from their beliefs highlights a potential area for further exploration. Given the importance of increasing participation by students from diverse backgrounds into science fields, it is critical to recognize how some of these differences may be the key factors influencing the way these students look at the world. This study offers evidence that science educators need to consider what role religious beliefs have for students who may be considering science or science education as a future career, particularly for those students from underrepresented groups.

Jung, Yeon Sub; Song, Tae Young

2011-01-01

NETEC is on the frontier to support Korean nuclear power plants. Requests of service are distributed through web based system. Human factor requests are occasionally posted. This paper analyzes interesting human factors requests/responses serviced, and summarizes the lesson learned. Subjects of the service include man machine interface, equipment label, procedure writing, procedure adherence, BISI, hand switch and alarm tile. Specifically the man machine interface is related to control command generated by acknowledge button, arrangement of switches. Procedure writing is about how to write contingency actions with proper numbering scheme. BISI is analyzed in view of automation level. Alarm tile is about how to handle the common alarm tile originated from local alarm boards. These topics seem to be legacies of past technology. Even though there are still human engineering discrepancies, these have been less evaluated because the topics need knowledge of other field domains

Peer support by persons affected with diabetes improves peer supporter's diabetes self-management skills. Peer support interventions by individuals who have diabetes or are affected by diabetes have been shown to improve glycemic control; however, its effects on other cardiovascular disease risk factors in adults with diabetes are unknown. We aimed to estimate the effect of peer support interventions on cardiovascular disease risk factors other than glycemic control in adults with diabetes. We conducted a systematic review and meta-analysis of randomized controlled trials comparing peer support interventions to a control condition in adults affected by diabetes that measured any cardiovascular disease risk factors [Body Mass Index, smoking, diet, physical activity, cholesterol level, glucose control and blood pressure]. Quality was assessed by Cochrane's risk of bias tool. We calculated standardized mean difference effect sizes using random effects models. We retrieved 438 citations from multiple databases including OVID MEDLINE, Cochrane database and Scopus, and author searches. Of 233 abstracts reviewed, 16 articles met inclusion criteria. A random effects model in a total of 3243 participants showed a positive effect of peer support interventions on systolic BP with a pooled effect size of 2.07 mmHg (CI 0.35 mmHg to 3.79 mmHg, p = 0.02); baseline pooled systolic blood pressure was 137 mmHg. There was a non-significant effect of peer support interventions on diastolic blood pressure, cholesterol, body mass index, diet and physical activity. Cardiovascular disease risk factors other than glycemic control outcomes were secondary outcomes in most studies and baseline values were normal or mildly elevated. Only one study reported smoking outcomes. We found a small (2 mmHg) positive effect of peer support interventions on systolic blood pressure in adults with diabetes whose baseline blood pressure was on average minimally elevated. Additional studies need to

Seismic damping tests of a prototypical Liquid Metal Fast Breeder Reactor (LMFBR) small-bore piping system is described, and measured transient responses to pulse excitations are reported. The test specimen was representative of a typical LMFBR insulated small-bore piping system, and it was supported from a rigid test fame by prototypic dead-weight supports, mechanical snubbers, and pipe clamps. Various support configurations were tested to assess the reponse sensitivity to insulation and use of mechanical snubbers. Factors much higher than the magnitudes currently allowed in design, by the USNRC Regulatory Guide 1.61, were found. This verified the design values but also pointed out the possibility of undue conservatism and costly overdesign resulting from use of the present design values

Numerical Study of Heat Transfer during Artificial Ground Freezing Combined with Groundwater Flow based on in-situ Measurement

2016-12-01

For civil engineering projects, especially in the subsurface with groundwater, the artificial ground freezing (AGF) method has been widely used. Commonly, a refrigerant is circulated through a pre-buried pipe network to form a freezing wall to support the construction. In many cases, the temperature change is merely considered as a result of simple heat conduction. However, the influence of the water-ice phase change on the flow properties should not be neglected, if large amount of groundwater with high flow velocities is present. In this work, we perform a 2D modelling (software: Comsol Multiphysics) of an AFG project of a metro tunnel in Southern China, taking groundwater flow into account. The model is validated based on in-situ measurement of groundwater flow and temperature. We choose a cross section of this horizontal AGF project and set up a model with horizontal groundwater flow normal to the axial of the tunnel. The Darcy velocity is a coupling variable and related to the temperature field. During the phase change of the pore water and the decrement of permeability in freezing zone, we introduce a variable of effective hydraulic conductivity which is described by a function of temperature change. The energy conservation problem is solved by apparent heat capacity method and the related parameter change is described by a step function (McKenzie, et. al. 2007). The results of temperature contour maps combined with groundwater flow velocity at different times indicate that the freezing wall appears in an asymmetrical shape along the groundwater flow direction. It forms slowly and on the upstream side the thickness of the freezing wall is thinner than that on the downstream side. The closure time of the freezing wall increases at the middle of the both up and downstream sides. The average thickness of the freezing wall on the upstream side is mostly affected by the groundwater flow velocity. With the successful validation of this model, this numerical

Social support is an essential component for the physical and emotional well-being of postpartum mothers. The objective of this study is to determine the psychometric properties of the revised Malay version Medical Outcome Study (MOS) Social Support Survey using a confirmatory validity approach. A cross-sectional study was conducted involving 144 postpartum mothers attending Obstetric and Gynecology Clinic, Universiti Sains Malaysia Hospital. Construct validity and internal consistency assessment was performed after the translation, content validity and face validity process. The data were analyzed using SPSS 20.0 (SPSS Inc., Chicago, IL, USA) and AMOS 20.0 (SPSS Inc., Chicago, IL, USA). The original questionnaire consists of four domains (emotional/informational support, tangible support, affectionate support and positive social interaction) and 19 items. Affectionate support domain with three items only was treated as a separate construct and was not included in the factor analysis. The final confirmatory model with three constructs and 13 items demonstrated acceptable factor loadings, domain to domain correlation and best fit; (χ2[df]=1.665 [61]; P-value=0.001; Tucker-Lewis Index=0.944; comparative fit index=0.956; root mean square error of approximation=0.068). Composite reliability, average variance extracted and Cronbach's α of the domains ranged from 0.649 to 0.903; 0.390 to 0.699; 0.616 to 0.902, respectively. The study suggested that the four-factor model with 16 items (including one separate factor of affectionate) of the revised Malay version MOS Social Support Survey was acceptable to be used to measure social support after childbirth because it is valid, reliable and simple. © 2015 Wiley Publishing Asia Pty Ltd.

transparency in reporting of conflict of interest is an increasingly important aspect of publication in medical journals. Publication of large industry-supported trials may generate many citations and journal income through reprint sales and thereby be a source of conflicts of interest for journals. We investigated industry-supported trials' influence on journal impact factors and revenue. we sampled six major medical journals (Annals of Internal Medicine, Archives of Internal Medicine, BMJ, JAMA, The Lancet, and New England Journal of Medicine [NEJM]). For each journal, we identified randomised trials published in 1996-1997 and 2005-2006 using PubMed, and categorized the type of financial support. Using Web of Science, we investigated citations of industry-supported trials and the influence on journal impact factors over a ten-year period. We contacted journal editors and retrieved tax information on income from industry sources. The proportion of trials with sole industry support varied between journals, from 7% in BMJ to 32% in NEJM in 2005-2006. Industry-supported trials were more frequently cited than trials with other types of support, and omitting them from the impact factor calculation decreased journal impact factors. The decrease varied considerably between journals, with 1% for BMJ to 15% for NEJM in 2007. For the two journals disclosing data, income from the sales of reprints contributed to 3% and 41% of the total income for BMJ and The Lancet in 2005-2006. publication of industry-supported trials was associated with an increase in journal impact factors. Sales of reprints may provide a substantial income. We suggest that journals disclose financial information in the same way that they require them from their authors, so that readers can assess the potential effect of different types of papers on journals' revenue and impact.

1993-01-01

The load distribution factor in the perforated square plate supporting by angle shape legs under concentrated load acting at arbitrary points through elastic media is calculated. For the calculation the perforated plate was converted into an orthotropic plate using the method suggested by J.B. Mahoney. The deflection for the calculation of the load distribution factor was obtained from the auxiliary plate which was extended both sides of the plate and it was compared with the results from ANSYS calculation. With this deflection, the calculation of the load distribution factor was performed. The result shows that the load distribution factor at the periphery of the plate is larger than that of in the central location. This load distribution factor could be used for re-distribution of the applied load in more accurate analysis of the plate as well as in the analysis of the elastic media as the load factor.

2009-01-01

The study of families irradiated as a result of the accident at the Chernobyl Nuclear Power Plant revealed significantly increased aberrant genomes frequencies (AGFs) not only in irradiated parents (n = 106, p 137 Cs) of peripheral blood samples from the children and their parents at doses of 0.1, 0.2 and 0.3 Gy. The spectrum and frequency of chromosome aberrations were studied in the 1st and 2nd cell generations. The average AGF was significantly increased at all doses (except 0.1 Gy) in children of irradiated parents, as compared to children born from non-irradiated parents. Amplification of cells with single-break chromosome aberrations in mitosis 2, as compared to mitosis 1, suggests the replication mechanism of realization of potential damage in DNA and the occurrence of genomic instability in succeeding cell generations.

2017-01-01

For the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS) together, this study examined support for a bifactor model, and also the internal consistency reliability and external validity of the factors in this model. Participants (N = 526) were adults from the general community who completed the SPS and SIAS. Confirmatory factor analysis (CFA) of their ratings indicated good support for the bifactor model. For this model, the loadings for all but six items were higher on the general factor than the specific factors. The three positively worded items had negligible loadings on the general factor. The general factor explained most of the common variance in the SPS and SIAS, and demonstrated good model-based internal consistency reliability (omega hierarchical) and a strong association with fear of negative evaluation and extraversion. The practical implications of the findings for the utilization of the SPS and SIAS, and the theoretical and clinical implications for social anxiety are discussed. PMID:28210232

2014-01-01

Stacks of elemental distribution images acquired by XRF can be difficult to interpret, if they contain high degrees of redundancy and components differing in their quantitative but not qualitative elemental composition. Factor analysis, mainly in the form of Principal Component Analysis (PCA), has been used to reduce the level of redundancy and highlight correlations. PCA, however, does not yield physically meaningful representations as they often contain negative values. This limitation can be overcome, by employing factor analysis that is restricted to non-negativity. In this paper we present the first application of the Python Matrix Factorization Module (pymf) on XRF data. This is done in a case study on the painting Saul and David from the studio of Rembrandt van Rijn. We show how the discrimination between two different Co containing compounds with minimum user intervention and a priori knowledge is supported by Non-Negative Matrix Factorization (NMF).

To investigate the relationship of nurse practitioners' social support as well as other factors associated with perceived self-efficacy. There is a growing demand for nurse practitioners in Taiwan, for whom self-perceived efficacy is associated with performance. Nevertheless, research on the self-efficacy and social support of nurse practitioners is limited. This is a cross-sectional survey study. Questionnaires were distributed to nurse practitioners in seven hospitals in northern Taiwan from May 2015 to March 2016. In total, data from 335 (78% return rate) certified nurse practitioners were analysed. Social support was measured by the Multidimensional Scale of Perceived Social Support (MSPSS) and the Job Content Questionnaire (JCQ), and perceived self-efficacy was measured by the General Self-Efficacy Scale (GSE). Data were analysed by ANOVAs with post hoc test and multiple linear regression. The mean score for self-efficacy was 27.60 ± 6.17. Support scores were 11.574 ± 2.37 for supervisors, 12.795 ± 1.92 for coworkers and 64.07 ± 10.16 for family, friends and significant others. nurse practitioners in the high monthly salary group had significantly higher self-efficacy than nurse practitioners in the medium and low monthly salary group (F = 8.99; p Social support from coworkers (β = 0.18, p social support were found to contribute to nurse practitioners' self-efficacy. Thus, to enhance nurse practitioners' self-efficacy and work performance, nursing leaders should address these issues. The findings inform hospital administrators to be aware of the importance of salary in relation to nurse practitioners' perceptions of social support and self-efficacy. © 2017 John Wiley & Sons Ltd.

2017-10-01

Full Text Available Through the use of an online survey and supporting interviews of funders, this study explores which factors are most influential in people’s decisions to financially back Kickstarter projects. Findings suggest that Kickstarter has several distinct benefits for those who support its projects and offers them an experience that traditional production channels cannot. The results also indicate that backers typically feel involved in the process of creating the projects they support, and they are willing to take risks to see projects that are important to them come to fruition. This research helps to improve our understanding of the attitudes that drive Kickstarter funding, and it helps project creators know what aspects of their campaigns prospective supporters find most important.

The importance of genetic and shared environmental factors for the associations between job demands, control, support and burnout.

Full Text Available Within occupational health research, one of the most influential models is the Job Demands-Control-Support model. Numerous studies have applied the model to different domains, with both physical and psychological health outcomes, such as burnout. The twin design provides a unique and powerful research methodology for examining the effects of environmental risk factors on burnout while taking familial factors (genetic and shared environment into account. The aim of the present study was to investigate the impact of familial factors on the associations of burnout with job demands, control and support. A total of 14,516 individuals from the Swedish Twin Registry, who were born between 1959 and 1986, and who participated in the Study of Twin Adults: Genes and Environment (STAGE by responding to a web-based questionnaire in 2005, were included in the analyses. Of these, there were 5108 individuals in complete same-sex twin pairs. Co-twin control analyses were performed using linear mixed modeling, comparing between-pairs effects and within-pair effects, stratified also by zygosity and sex. The results indicate that familial factors are of importance in the association between support and burnout in both women and men, but not between job demands and burnout. There are also tendencies towards familial factors being involved in the association between control and burnout in men. These results offer increased understanding of the mechanisms involved in the associations between work stress and burnout.

Little research has examined the characteristics of peer support. Pertinent to such examination may be characteristics such as the distinction between nondirective support (accepting recipients' feelings and cooperative with their plans) and directive (prescribing "correct" choices and feelings). In a peer support program for individuals with diabetes, this study examined (a) whether the distinction between nondirective and directive support was reflected in participants' ratings of support provided by peer supporters and (b) how nondirective and directive support were related to depressive symptoms, diabetes distress, and Hemoglobin A1c (HbA1c). Three hundred fourteen participants with type 2 diabetes provided data on depressive symptoms, diabetes distress, and HbA1c before and after a diabetes management intervention delivered by peer supporters. At post-intervention, participants reported how the support provided by peer supporters was nondirective or directive. Confirmatory factor analysis (CFA), correlation analyses, and structural equation modeling examined the relationships among reports of nondirective and directive support, depressive symptoms, diabetes distress, and measured HbA1c. CFA confirmed the factor structure distinguishing between nondirective and directive support in participants' reports of support delivered by peer supporters. Controlling for demographic factors, baseline clinical values, and site, structural equation models indicated that at post-intervention, participants' reports of nondirective support were significantly associated with lower, while reports of directive support were significantly associated with greater depressive symptoms, altogether (with control variables) accounting for 51% of the variance in depressive symptoms. Peer supporters' nondirective support was associated with lower, but directive support was associated with greater depressive symptoms.

Neutron Buildup Factors Calculation for Support Vector Regression Application in Shielding Analysis

International Nuclear Information System (INIS)

Duckic, P.; Matijevic, M.; Grgic, D.

2016-01-01

In this paper initial set of data for neutron buildup factors determination using Support Vector Regression (SVR) method is prepared. The performance of SVR technique strongly depends on the quality of information used for model training. Thus it is very important to provide representable data to the SVR. SVR is a supervised type of learning so it demands data in the input/output form. In the case of neutron buildup factors estimation, the input parameters are the incident neutron energy, shielding thickness and shielding material and the output parameter is the neutron buildup factor value. So far the initial sets of data for different shielding configurations have been obtained using SCALE4.4 sequence SAS3. However, this results were obtained using group constants, thus the incident neutron energy was determined as the average value for each energy group. Obtained this way, the data provided to the SVR are fewer and therefore insufficient. More valuable information is obtained using SCALE6.2beta5 sequence MAVRIC which can perform calculations for the explicit incident neutron energy, which leads to greater maneuvering possibilities when active learning measures are employed, and consequently improves the quality of the developed SVR model.(author).

Our aim was to explore reasons for physician variability in decisions to limit life support in the intensive care unit (ICU) utilizing qualitative methodology. Single center study consisting of semi-structured interviews with experienced physicians and nurses. Seventeen intensivists from medical (n = 7), surgical (n = 5), and anesthesia (n = 5) critical care backgrounds, and ten nurses from medical (n = 5) and surgical (n = 5) ICU backgrounds were interviewed. Principles of grounded theory were used to analyze the interview transcripts. Eleven factors within four categories were identified that influenced physician variability in decisions to limit life support: (1) physician work environment-workload and competing priorities, shift changes and handoffs, and incorporation of nursing input; (2) physician experiences-of unexpected patient survival, and of limiting life support in physician's family; (3) physician attitudes-investment in a good surgical outcome, specialty perspective, values and beliefs; and (4) physician relationship with patient and family-hearing the patient's wishes firsthand, engagement in family communication, and family negotiation. We identified several factors which physicians and nurses perceived were important sources of physician variability in decisions to limit life support. Ways to raise awareness and ameliorate the potentially adverse effects of factors such as workload, competing priorities, shift changes, and handoffs should be explored. Exposing intensivists to long term patient outcomes, formalizing nursing input, providing additional training, and emphasizing firsthand knowledge of patient wishes may improve decision making.

Tuberculosis (TB) services in six Russian regions in which social support programmes for TB patients were implemented. To identify risk factors for default and to evaluate possible impact of social support. Retrospective study of new pulmonary smear-positive and smear-negative TB patients registered during the second and third quarters of the 2003. Data were analysed in a case-control study including default patients as cases and successfully treated patients as controls, using multivariate logistic regression modelling. A total of 1805 cases of pulmonary TB were enrolled. Default rates in the regions were 2.3-6.3%. On multivariate analysis, risk factors independently associated with default outcome included: unemployment (OR 4.44; 95%CI 2.23-8.86), alcohol abuse (OR 1.99; 95%CI 1.04-3.81), and homelessness (OR 3.49; 95%CI 1.25-9.77). Social support reduced the default outcome (OR 0.13; 95%CI 0.06-0.28), controlling for age, sex, region, residence and acid-fast bacilli (AFB) smear of sputum. Unemployment, alcohol abuse and homelessness were associated with increased default outcome among new TB patients, while social support for TB patients reduced default. Further prospective randomised studies are necessary to evaluate the impact and to determine the most cost-effective social support for improving treatment outcomes of TB in patients in Russia, especially among populations at risk of default.

Improvement of chronic disease management in primary care entails monitoring indicators of quality over time and across patients and practices. Informatics tools are needed, yet implementing them remains challenging. To identify critical success factors enabling the translation of clinical and operational knowledge about effective and efficient chronic care management into primary care practice. A prospective case study of positive deviants using key informant interviews, process observation, and document review. A chronic disease management (CDM) collaborative of primary care physicians with documented improvement in adherence to clinical practice guidelines using a web-based patient registry system with CDM guideline-based flow sheet. Thirty community-based physician participants using predominantly paper records, plus a project management team including the physician lead, project manager, evaluator and support team. A critical success factor (CSF) analysis of necessary and sufficient pathways to the translation of knowledge into clinical practice. A web-based CDM 'toolkit' was found to be a direct CSF that allowed this group of physicians to improve their practice by tracking patient care processes using evidence-based clinical practice guideline-based flow sheets. Moreover, the information and communication technology 'factor' was sufficient for success only as part of a set of seven direct CSF components including: health delivery system enhancements, organizational partnerships, funding mechanisms, project management, practice models, and formal knowledge translation practices. Indirect factors that orchestrated success through the direct factor components were also identified. A central insight of this analysis is that a comprehensive quality improvement model was the CSF that drew this set of factors into a functional framework for successful knowledge translation. In complex primary care settings environment where physicians have low adoption rates of

Understanding factors associated with early therapeutic alliance in PTSD treatment: adherence, childhood sexual abuse history, and social support.

Therapeutic alliance has been associated with better treatment engagement, better adherence, and less dropout across various treatments and disorders. In treatment of posttraumatic stress disorder (PTSD), it may be particularly important to establish a strong early alliance to facilitate treatment adherence. However, factors such as childhood sexual abuse (CSA) history and poor social support may impede the development of early alliance in those receiving PTSD treatment. We sought to examine treatment adherence, CSA history, and social support as factors associated with early alliance in individuals with chronic PTSD who were receiving either prolonged exposure therapy (PE) or sertraline. At pretreatment, participants (76.6% female; 64.9% Caucasian; mean age = 37.1 years, SD = 11.3) completed measures of trauma history, general support (Inventory of Socially Supportive Behaviors), and trauma-related social support (Social Reactions Questionnaire). Over the course of 10 weeks of PE or sertraline, they completed early therapeutic alliance (Working Alliance Inventory) and treatment adherence measures. Early alliance was associated with PE adherence (r = .32, p history was not predictive of a lower early alliance. Given the associations with adherence, clinicians may find it useful to routinely assess alliance early in treatment. Positive trauma support, not CSA history, may be particularly important in the development of a strong early therapeutic alliance. (c) 2010 APA, all rights reserved.

Peer providers are a promising practice for transition-age youth community mental health treatment engagement and support, yet little is known about the experience of being a young adult peer provider or what helps to make an individual in this role successful. Utilizing a capital theory lens, this study uses data from focus groups (two with young adult peer providers and two with their supervisors) to examine facilitators of young adult peer provider success in community mental health treatment settings. Eight factors were identified as critical to young adult peer provider on-the-job success: persistence, job confidence, resilience, job training, skilled communications with colleagues, regular and individualized supervision, support from colleagues, and family support. Findings suggest that young adult peer providers may benefit immensely from an agency level focus on fostering social organizational capital as well as more individualized efforts to increase cultural, social, and psychological capital through training and supervision.

Full Text Available Background: When people face health problems, their life satisfaction levels and social relations could be ruined. When it comes to an eerie, deadly and chronic disease like cancer, the individual is much more likely to be affected by it. Objective: This descriptive study aims to identify quality of life and level of social support and the affecting factors in cancer patients. Methods: The sample included 170 patients who applied to Internal Diseases, Radiation Oncology, Thorax diseases clinics and Chemotherapy polyclinic in a university hospital in Turkey between March and August, 2005, who met the research criteria, and who volunteered to participate in the study. The sample represented 20 % of the target population. Data were collected through SF-36 Quality of Life Scale and Multidimensional Scale of Perceived Social Support. Results: The patients’ Global Quality of Life mean score was found 38.67 ± 13.64, and mean score for the Perceived Social Support was found 59.19 ± 17.5. Global Quality of Life score was higher in those who underwent an operation and who received ambulatory health care. Although Global Quality of Life was not influenced by the gender variable, male patients’ level of well-being was found to be higher. Perceived Social Support total score was found to be higher in those who knew about their disease. Family support was found to be higher in those who were married and who lived in town; it was found to be low in those who had low socio-economic level and who received inpatient treatment. Friend support was found to be high in those who knew about their disease. Conclusion: There was a linear relationship between Perceived Social Support and Quality of Life. It is recommended that more studies with wider groups of participants would shed more light to the issue of identifying quality of life, social support level and the relationships between them in cancer patients.

This study was carried out to determine the level of support towards the proposed National Health Insurance scheme among Malaysian patients attending specialist clinics at the National University of Malaysia Medical centre and its influencing factors. The cross sectional study was carried out from July-October 2012. 260 patients were selected using multistage sampling method. 71.2% of respondents supported the proposed National Health insurance scheme. 61.4% of respondents are willing to pay up to RM240 per year to join the National Health Insurance and 76.6% of respondents are of the view that enrolment in NHI should be made compulsory. Knowledge had a positive influence on respondent's support towards National Health Insurance. National Health Insurance when implemented in Malaysia can be used to raise funds for health care financing, increase access to health services and achieve the desired health status. More efforts should be taken to promote the scheme and educate the public in order to achieve higher support towards the proposed National Health Insurance. The cost to enroll in NHI as well as services to be included under the scheme should be duly considered. PMID:23985101

Depression, a type of mental disorder which is portrayed by marked alterations in mood, is associated with distress and/or impaired functioning. Poor social support is an important risk factor for depression in pregnancy. An extensive literature search failed to show any published study conducted in Malaysia on antenatal depressive symptoms and the risk of poor social support on it. The aim of the study was to determine the risk of antenatal depressive symptoms due to poor social support. This cross sectional study was conducted among 3000 pregnant women attending antenatal clinics in Penang, Malaysia. Edinburgh Postnatal Depression Scale (EPDS) was used to screen for antenatal depressive symptoms and the Oslo-3 Social Support Scale (OSS-3) was used to measure social support. Odds ratio and adjusted odds ratio were used to quantify the risk of antenatal depressive symptoms due to poor social support. The prevalence of depressive symptoms was 20%. Using OSS-3 scale to gauge social support, most of the participants had moderate support (61.3%) followed by poor support (22%) and strong support (16.7%). Social support was found to be significantly associated with depressive symptoms in this study (OR 2.2, aOR 2.1, AR 45%). Considering that an expecting mother's psychological factors are important in the wellbeing of the mother and child, antenatal depression must be quickly identified. Screening pregnant women for social support can help identify women with higher risk of depression.

Full Text Available Previous studies have shown that socio-demographic factors, childhood socioeconomic status (CSES, childhood traumatic experiences (CTEs, social support and behavioural factors are associated with health and well-being in adulthood. However, the relative importance of these factors for mental health, health, and well-being has not been studied. Moreover, the mechanisms by which CTEs affect mental health, health, and well-being in adulthood are not clear. Using data from a representative sample (n=12,981 of the adult population in Tromsø, Norway, this study examines (i the relative contribution of structural conditions (gender, age, CSES, psychological abuse, physical abuse, and substance abuse distress to social support and behavioural factors in adulthood ; (ii the relative contribution of socio-demographic factors, CSES, CTEs, social support, and behavioural factors to three multi-item instruments of mental health (SCL-10, health (EQ-5D, and subjective well-being (SWLS in adulthood; (iii the impact of CTEs on mental health, health, and well-being in adulthood, and; (iv the mediating role of adult social support and behavioural factors in these associations. Instrumental support (24.16%, p<0.001 explained most of the variation in mental health, while gender (21.32%, p<0.001 explained most of the variation in health, and emotional support (23.34%, p<0.001 explained most of the variation in well-being. Psychological abuse was relatively more important for mental health (12.13%, health (7.01%, and well-being (9.09%, as compared to physical abuse, and substance abuse distress. The subjective assessment of childhood financial conditions was relatively more important for mental health (6.02%, health (10.60%, and well-being (20.60%, as compared to mother’s and father’s education. CTEs were relatively more important for mental health, while, CSES was relatively more important for health and well-being. Respondents exposed to all three types of CTEs

2008-09-01

Active support (AS) has been shown to increase the amount of time that residents in shared residential settings are involved in purposeful activities. The organisational processes required to implement AS have been less well researched. Staff in community houses answered questions about the occurrence of organisational activities and processes thought to assist AS implementation (e.g., training and teamwork), their understanding of engagement, and their experience of changes in staff practice consistent with AS (including implementation problems). Non-house-based managers were also interviewed about their role in AS implementation. Reported occurrence of organisational activities and processes (e.g., training and teamwork) and understanding of engagement were associated with more reports of changes in staff practice and fewer staff reports of implementation problems. Staff reports on the role of non-house-based managers were not associated with reports of changes in staff practice or with reports of fewer AS implementation problems. Non-house-based managers' reports overestimated their role in AS implementation when compared with reports from house-based staff groups. While there are limitations in the research design (including the reliance on staff reports), the findings support the importance of wider organisational factors (beyond training programs for direct support staff) as integral to the implementation of AS. There is a need for further research on AS implementation.

Staff and prisoner perceptions of physical and social environmental factors thought to be supportive of bullying: the role of bullying and fear of bullying.

Science.gov (United States)

Allison, Matthew D; Ireland, Jane L

2010-01-01

The current study explored the relationship between social and physical environmental factors supportive of bullying, levels of bullying and fear of bullying. Participants were 261 adult male prisoners. All completed the Direct and Indirect Prisoner Checklist-Scaled Version Revised (DIPC-SCALED-r Ireland, 2007), the Prison Environment Scale (PES Allison, 2007), and a Brief Measure of Fear of Bullying Scale (BMFBS). The PES was explored initially using 100 male prisoners randomly selected from the main sample and 100 prison officers. It was predicted that increased bullying would be associated with increased evidence of environmental factors supportive of bullying; that increased levels of fear of bullying would be associated with increased evidence of environmental factors supportive of bullying; and that actual experience of bullying would represent better predictors of fear levels than the presence of environmental factors supportive of bullying. Those perceiving greater levels of environmental factors reported more fear of bullying and more behaviours indicative of bullying (perpetration and victimisation), with this holding for indirect and direct behaviours indicative of bullying. Bullying behaviours (direct perpetration and indirect victimisation) predicted fear of bullying more than the presence of environmental factors. The environmental factor of rules, regulations and security were found to predict bullying perpetration. Copyright 2009 Elsevier Ltd. All rights reserved.

Predicting suicide ideation through intrapersonal and interpersonal factors: The interplay of Big-Five personality traits and social support.

2015-11-01

While a specific personality trait may escalate suicide ideation, contextual factors such as social support, when provided effectively, may alleviate the effects of such personality traits. This study examined the moderating role of social support in the relationship between the Big-Five personality traits and suicide ideation. Significant interactions were found between social support and extraversion and emotional stability. Specifically, the relationship between emotional stability and extraversion to suicide ideation was exacerbated when social support was low. Slope analysis showed openness also interacted with low social support. Results were computed for frequency, duration and attitude dimensions of suicide ideation. Extraversion interacted with social support to predict all three dimensions. Social support moderated emotional stability to predict frequency and duration, moderated conscientiousness towards frequency and attitude, and moderated openness towards attitude. The results imply that whereas personality traits may be difficult to alter, social support may play a significant role in saving a life. Psychologists should include family and friends when treating a suicidal youth, guiding them to awareness of one's personality and being more supportive. Copyright © 2015 John Wiley & Sons, Ltd.

A certain level of public support for smoke-free environments is a prerequisite for adoption and enforcement of policies and can be used as an indicator of readiness for legislative action. This study assessed support for comprehensive smoke-free policies in a range of settings such as hotels and colleges among government workers in China and identified factors associated with support for smoke-free policies. Understanding the extent to which government workers, a large segment of the working population in China, report a smoke-free workplace and support for smoke-free policies may be important indicators of readiness for strengthened policies given their role in formulating, implementing and enforcing regulations. Data were from an evaluation of the Tobacco Free Cities initiative of Emory University's Global Health Institute-China Tobacco Control Partnership. Self-administered surveys were completed by 6,646 workers in 160 government agencies in six Chinese cities. Multivariate logistic regression was used to identify factors associated with support for smoke-free worksites, bars, hotels, and colleges. Over half (54.6%) of participants were male. A large percentage of the male workers smoked (45.9%,) whereas very few women did (1.9%). Fewer than 50% of government workers reported smoke-free policies at work, with 19.0% reporting that smoking is allowed anywhere. Support for smoke-free policies was generally very high, with the lowest levels of support for smoke-free bars (79.0%) and hotels (82.3%), higher levels of support for restaurants (90.0%) and worksites (93.0%), and above 95% support for hospitals, schools, colleges, public transportation and religious settings. Knowledge of the harmfulness of secondhand smoke was positively associated with support for smoke-free policies. Stricter worksite smoking policies were associated with support for smoke-free workplaces and bars, but not hotels and colleges. Women and nonsmokers were more supportive of smoke

Great Lakes water quality initiative technical support document for the procedure to determine bioaccumulation factors. Draft report

International Nuclear Information System (INIS)

1993-03-01

The purpose of the document is to provide the technical information and rationale in support of the proposed procedures to determine bioaccumulation factors. Bioaccumulation factors, together with the quantity of aquatic organisms eaten, determine the extent to which people and wildlife are exposed to chemicals through the consumption of aquatic organisms. The more bioaccumulative a pollutant is, the more important the consumption of aquatic organisms becomes as a potential source of contaminants to humans and wildlife. Bioaccumulation factors are needed to determine both human health and wildlife tier I water quality criteria and tier II values. Also, they are used to define Bioaccumulative Chemicals of Concern among the Great Lakes Initiative universe of pollutants. Bioaccumulation factors range from less than one to several million

Scientific literature has identified different vulnerability factors associated to abuse in people with dementia (PWD), but little is known about the psychosocial protective variables against abuse. The main objective of this study is to investigate a set of caregiver and patient factors linked to abuse-related behavior of PWD. A total of 326 primary and family caregivers, residents of the Castilla and León community (Spain), were evaluated. All participants filled out a standardized protocol, which assessed the sociodemographic characteristics, patient and care-related variables, as well as the perceived burden, resilience, and social support. Abuse-related behavior was evaluated using the Caregiver Abuse Screen. Results show that the severity of cognitive impairment and behavior disorders of PWD, a greater number of caregiving hours, a worse previous relationship with the caregiver, and perceived burden are positively related with abuse. However, resilience and social support showed a negative relationship with Caregiver Abuse Screen scores, suggesting a protective effect on abuse, even after controlling the effect of a number of covariates. Indeed, resilience was the only variable that remained significant after including the effect of burden. This paper states the role of burden in abuse of PWD, while resilience and social support are abuse protective factors. These variables should be considered in future guidelines for the prevention of abuse against PWD. Copyright © 2018 John Wiley & Sons, Ltd.

Salmonella Enteritidis and Salmonella Typhimurium are among the most prevalent serotypes isolated from salmonellosis outbreaks and poultry. Salmonella spp. have the capacity to form biofilms on several surfaces, which can favour survival in hostile environments, such as slaughterhouses. Salmonella strains present differences in pathogenicity. However, there is little information regarding the pathogenicity of S. Enteritidis and S. Typhimurium isolated from avian sources and their relationship to biofilm production. The aim of this study was to use a novel pathogenicity index and a biofilm production assay to evaluate their relationships within these serotypes. In addition, we detected the presence of the spiA and agfA genes in these strains. Biofilm formation was investigated at two temperatures (37 °C and 28 °C) using microtiter plate assay, and the results were compared with the individual pathogenicity index of each strain. PCR was used to detect spiA and agfA, virulence genes associated with biofilm production. S. Enteritidis and S. Typhimurium strains were capable of producing biofilm at 37 °C and 28 °C. Sixty-two percent and 59.5% of S. Enteritidis and 73.8% and 46.2% of S. Typhimurium produced biofilm at 37 °C and 28 °C, respectively. Biofilm production at 37 °C was significantly higher in both serotypes. Only S. Enteritidis was capable of adhering strongly at both temperatures. Biofilm production was related to pathogenicity index only at 28 °C for S. Enteritidis. spiA and agfA were found in almost all strains and were not statistically associated with biofilm production.

Breastfeeding rates fall short of goals set in Healthy People 2010 and other national recommendations. The current, national breastfeeding continuation rate of 29% at 6 months lags behind the Healthy People 2010 goal of 50%. The objective of this study was to evaluate associations between breastfeeding discontinuation at 2 and 12 weeks postpartum and clinician support, maternal physical and mental health status, workplace issues, and other factors amenable to intervention. A prospective cohort study was conducted of low-risk mothers and infants who were in a health maintenance organization and enrolled in a randomized, controlled trial of home visits. Mothers were interviewed in person at 1 to 2 days postpartum and by telephone at 2 and 12 weeks. Logistic regression modeling was performed to assess the independent effects of the predictors of interest, adjusting for sociodemographic and other confounding variables. Of the 1163 mother-newborn pairs in the cohort, 1007 (87%) initiated breastfeeding, 872 (75%) were breastfeeding at the 2-week interview, and 646 (55%) were breastfeeding at the 12-week interview. In the final multivariate models, breastfeeding discontinuation at 2 weeks was associated with lack of confidence in ability to breastfeed at the 1- to 2-day interview (odds ratio [OR]: 2.8; 95% confidence interval [CI]: 1.02-7.6), early breastfeeding problems (OR: 1.5; 95% CI: 1.1-1.97), Asian race/ethnicity (OR: 2.6; 95% CI: 1.1-5.7), and lower maternal education (OR: 1.5; 95% CI: 1.2-1.9). Mothers were much less likely to discontinue breastfeeding at 12 weeks postpartum if they reported (during the 12-week interview) having received encouragement from their clinician to breastfeed (OR: 0.6; 95% CI: 0.4-0.8). Breastfeeding discontinuation at 12 weeks was also associated with demographic factors and maternal depressive symptoms (OR: 1.18; 95% CI: 1.01-1.37) and returning to work or school by 12 weeks postpartum (OR: 2.4; 95% CI: 1.8-3.3).

The study assessed mothers' risk for abusing their children in middle adolescence in relation to individual and contextual factors during the economic crisis in Croatia. Socioeconomic status of mothers, family economic pressure, and mothers' exposure to stress were measured. Special attention was given to the perceived availability of social support as one of protective factors potentially buffering the negative impact of risks of child abuse. The community sample included 746 mothers (Mage = 42.85; SDage = 5.319). The results showed that the risk of child abuse is higher for mothers with lower education, those who perceive themselves as suffering greater family economic hardship, those who have experienced a higher number of stressful events, and those with lower social support. When the mothers perceive a lower availability of social support, the effects of exposure to cumulative risk, namely the combination of socioeconomic status, economic pressure, and exposure to stress, are stronger. Since social support proved to be one of the key protective factors in the relationship between adverse life circumstances and parenting, the development of effective and non-stigmatized interventions aiming to increase social support, positive social relationships, and adequate parenting practices for parents facing economic hardship is an important direction for future family policy measures.

Kovesdi, C.; Joe, J.; Boring, R.

2017-05-01

The primary objective of the United States (U.S.) Department of Energy (DOE) Light Water Reactor Sustainability (LWRS) program is to sustain operation of the existing commercial nuclear power plants (NPPs) through a multi-pathway approach in conducting research and development (R&D). The Advanced Instrumentation, Information, and Control (II&C) System Technologies pathway conducts targeted R&D to address aging and reliability concerns with legacy instrumentation and control (I&C) and other information systems in existing U.S. NPPs. Control room modernization is an important part following this pathway, and human factors experts at Idaho National Laboratory (INL) have been involved in conducting R&D to support migration of new digital main control room (MCR) technologies from legacy analog and legacy digital I&C. This paper describes a human factors engineering (HFE) process that supports human-system interface (HSI) design in MCR modernization activities, particularly with migration of old digital to new digital I&C. The process described in this work is an expansion from the LWRS Report INL/EXT-16-38576, and is a requirements-driven approach that aligns with NUREG-0711 requirements. The work described builds upon the existing literature by adding more detail around key tasks and decisions to make when transitioning from HSI Design into Verification and Validation (V&V). The overall objective of this process is to inform HSI design and elicit specific, measurable, and achievable human factors criteria for new digital technologies. Upon following this process, utilities should have greater confidence with transitioning from HSI design into V&V.

Methods: A total of 220 MDR-TB patients participated in the questionnaire-based survey, and the data from 212 valid questionnaires were analyzed. The respondents reported their sociodemographic status, disease features, and attitudes toward the disease. The social support rating scale was used to measure the patients’ social support scores. An Independent Samples t-test, one-way analysis of variance, and a multiple linear regression model were used to analyze the related factors for the social support scores. Result: The average social support score of each MDR-TB patient was 32.56±7.86. Participants who were single, widowed or divorced, retired, and had fewer family members and lower family income were found to have lower social support scores. Participants unwilling to disclose their disease tended to have less social support (31.59<34.23, P=0.010. Participants who perceived great help from health care workers reported higher social support rating scale scores than those who perceived no help (35.36>29.89, P=0.014. Conclusion: MDR-TB patients in Zhejiang Province were shown to have a low level of social support. Patients who were not married, had smaller families, and lower family income received less social support, suggesting that family harmony could be an important source of social support. Patients�

Despite the protective effect of male circumcision (MC) against HIV in men, the acceptance of voluntary MC in priority countries for MC scale-up such as Uganda remains limited. This study examined the role of women's sociodemographic characteristics, knowledge of HIV and sexual bargaining power as determinants of women's support of male circumcision (MC). Data from the Uganda AIDS Indicator Survey, 2011 were analyzed (n = 4,874). Bivariate and multivariate logistic regression analyses with random intercept were conducted to identify factors that influence women's support of MC. Overall, 67.0 % (n = 3,276) of the women in our sample were in support of MC but only 28.0 % had circumcised partners. Women who had the knowledge that circumcision reduces HIV risk were about 6 times as likely to support MC than women who lacked that knowledge [AOR (adjusted odds ratio) = 5.85, 95 % CI (confidence interval) = 4.83-7.10]. The two indicators of women's sexual bargaining power (i.e., ability to negotiate condom use and ability to refuse sex) were also positively associated with support of MC. Several sociodemographic factors particularly wealth index were also positively associated with women's support of MC. The findings in this study will potentially inform intervention strategies to enhance uptake of male circumcision as a strategy to reduce HIV transmission in Uganda.

Factors of accepting pain management decision support systems by nurse anesthetists

Science.gov (United States)

2013-01-01

Background Pain management is a critical but complex issue for the relief of acute pain, particularly for postoperative pain and severe pain in cancer patients. It also plays important roles in promoting quality of care. The introduction of pain management decision support systems (PM-DSS) is considered a potential solution for addressing the complex problems encountered in pain management. This study aims to investigate factors affecting acceptance of PM-DSS from a nurse anesthetist perspective. Methods A questionnaire survey was conducted to collect data from nurse anesthetists in a case hospital. A total of 113 questionnaires were distributed, and 101 complete copies were returned, indicating a valid response rate of 89.3%. Collected data were analyzed by structure equation modeling using the partial least square tool. Results The results show that perceived information quality (γ=.451, pDSS. Information quality (γ=.267, pDSS ease of use. Furthermore, both perceived ease of use (β=.436, pDSS acceptance (R2=.640). Thus, the critical role of information quality in the development of clinical decision support system is demonstrated. Conclusions The findings of this study enable hospital managers to understand the important considerations for nurse anesthetists in accepting PM-DSS, particularly for the issues related to the improvement of information quality, perceived usefulness and perceived ease of use of the system. In addition, the results also provide useful suggestions for designers and implementers of PM-DSS in improving system development. PMID:23360305

Disparities between the health of Indigenous and non-Indigenous populations continue to be prevalent within Australia. Research suggests that Indigenous people participate in health risk behaviour more often than their non-Indigenous counterparts, and that such behaviour has a substantial impact on health outcomes. Although this would indicate that reducing health risk behaviour may have positive effects on health outcomes, the factors that influence Indigenous health behaviour are still poorly understood. This study aimed to interview people who support Indigenous groups to gain an understanding of their views on the factors influencing health behaviour within Indigenous groups in Western Australia. Twenty nine people participated in the study. The emergent themes were mapped against the social ecological model. The results indicated that: (1) culture, social networks, history, racism, socioeconomic disadvantage, and the psychological distress associated with some of these factors interact to affect health behaviour in a complex manner; (2) the desire to retain cultural identity and distinctiveness may have both positive and negative influence on health risk behaviour; (3) strong social connections to family and kin that is intensified by cultural obligations, appears to affirm and disrupt positive health behaviour; (4) the separation between Indigenous and non-Indigenous social connection/networks that appeared to be fostered by marginalisation and racism may influence the effect of social networks on health behaviour; and (5) communication between Indigenous and non-Indigenous people may be interrupted by distrust between the groups, which reduces the influence of some non-Indigenous sources on the health behaviour of Indigenous people.

Full Text Available With industrialization, change has taken place in the world and development efforts have concentrated in urban areas. This has affected the rural area negatively and the increase in rural development studies has increased with the emergence of interregional economic imbalances. With the planned period, rural development studies in Turkey have increased and strategies, projects and programs have begun to be developed. One of these activities is the Rural Development Investment Support Program (RDISP, which entered into force in 2006. The aim of the program is to increase the level of rural area income, to ensure integration of agricultural production and agricultural industry, to strengthen food safety, to create alternative income sources in the rural area. In this study, it was aimed to determine the attitudes and behaviors of program beneficiaries in the Western Mediterranean Region within the framework of the RDISP applied in Turkey, and the factors affecting their utilization from the program. In the study, a total of 96 enterprises provided interviews based on face to face interviews. In this study, Factor Analysis was applied to determine the factors that affect the preferences of the enterprises and to determine the factors affecting the investments of the enterprises. In the study, 12 variables that were effective in factor analysis in the utilization of this support were combined into 3 factors. These factors have been found to be “support for local support and information about support”, “employment support for support” and “environmental sensitivity for support”.

Full Text Available Abstract Background The UK has one of the lowest breastfeeding rates worldwide and in recent years the Government has made breastfeeding promotion one of its priorities. The UNICEF UK Baby Friendly Initiative is likely to increase breastfeeding initiation but not duration. Other strategies which involve provision of support for breastfeeding mothers in the early weeks after birth are therefore required to encourage UK mothers to breastfeed for the recommended duration. This paper examines the effects of maternal socio-demographic factors, maternal obstetric factors, and in-hospital infant feeding practices on breastfeeding cessation in a peer support setting. Methods Data on mothers from Blackburn with Darwen (BwD and Hyndburn in Eastern Lancashire who gave birth at the Royal Blackburn Hospital and initiated breastfeeding while in hospital were linked to the Index of Multiple Deprivation (IMD. The data were analysed to describe infant feeding methods up to 6 months and the association between breastfeeding cessation, and maternal factors and in-hospital infant feeding practices. Results The mean breastfeeding duration was 21.6 weeks (95% CI 20.86 to 22.37 weeks and the median duration was 27 weeks (95% CI 25.6 to 28.30 weeks. White mothers were 69% more likely to stop breastfeeding compared with non-White mothers (HR: 0.59; 95% CI, 0.52 to 0.67 [White mothers were the reference group]. Breastfeeding cessation was also independently associated with parity and infant feeding practices in hospital. There were no significant associations between breastfeeding cessation and marital status, mode of delivery, timing of breastfeeding initiation and socio-economic deprivation. Conclusion In this study ethnicity, parity and in-hospital infant feeding practices remained independent predictors of breastfeeding cessation in this peer support setting. However other recognised predictors such as marital status, mode of delivery, timing of breastfeeding

The EU's Green Rotorcraft programme is pursuing the development of a functional and airworthy Active Gurney Flap (AGF) for a full-scale helicopter rotor blade. Interest in the development of this `smart adaptive rotor blade' technology lies in its potential to provide a number of aerodynamic benefits, which would in turn translate into a reduction in fuel consumption and noise levels. The AGF mechanism selected employs leaf-spring crossed flexure pivots. These provide important advantages over bearings as they are not susceptible to seizing and do not require maintenance (i.e. lubrication or cleaning). A baseline design of this mechanism was successfully tested both in a fatigue rig and in a 2D wind tunnel environment at flight-representative deployment schedules. For full validation, a flight test would also be required. However, the severity of the in-flight loading conditions would likely compromise the mechanical integrity of the pivots' leaf-springs in their current form. This paper investigates the scope for stress reduction through three-dimensional shape optimization of the leaf-springs of a generic crossed flexure pivot. To this end, a procedure combining a linear strain energy formulation, a parametric leaf-spring profile definition and a series of optimization algorithms is employed. The resulting optimized leaf-springs are proven to be not only independent of the angular rotation at which the pivot operates, but also linearly scalable to leaf-springs of any length, minimum thickness and width. Validated using non-linear finite element analysis, the results show very significant stress reductions relative to pivots with constant cross section leaf-springs, of up to as much as 30% for the specific pivot configuration employed in the AGF mechanism. It is concluded that shape optimization offers great potential for reducing stress in crossed flexure pivots and, consequently, for extending their fatigue life and/or rotational range.

Close or renew? Factors affecting local community support for rebuilding nuclear power plants in the Czech Republic

Rebuilding and upgrading of existing nuclear power plants represent a great energy policy challenge today. In this paper, factors that affect local community support for the rebuilding of an existing nuclear power plant are explored using a regression analysis model. It is based on a survey involving nearly 600 residents of twelve municipalities located in the vicinity of the Dukovany power plant in the Czech Republic. Nearly two thirds of local population support the rebuilding of the plant. The support for rebuilding is not directly affected by distance of residence from the power plant or perceptions of its local economic impacts, but is more influenced by general perceptions of pros of nuclear power. Work in the power plant, perception of nuclear power as a clean energy contributing to climate change mitigation and negative attitude to the renewable energy development are strongest predictors of the support. In terms of energy policy implications, it seems that the education of the public and awareness of nuclear power plants as a clean, safe and landscape compatible system of energy production are more important for increasing acceptance of rebuilding projects than spatial distribution of economic benefits to local communities. - Highlights: • Predictors of support for nuclear power plant (NPP) rebuilding are explored. • Support is not affected by distance or perception of local economic impacts. • Support is affected by general perceptions of pros of NPPs. • Support is determined by perception of NPPs as a clean energy. • Support is correlated with a negative attitude to renewable energy promotion.

Recently Fe/Ag thin films have been intensively investigated due to their special magnetic properties. To study the stability of the Fe-Ag interfaces very long time experiments are necessary at room temperature. To enhance the processes which take place at interfaces, high temperature annealing can be used. A detailed annealing experiment was carried out on Si-covered Fe/Ag (Ag grown on Fe) and Ag/Fe (Fe grown on Ag) polycrystalline bilayers, which were deposited on Si(1 1 1) substrates by MBE method. Heat treatments of various duration and temperature were applied in UHV conditions. Rutherford backscattering spectrometry and X-ray diffractometry were used to determine the effects of the heat treatments. In case of Fe/Ag samples, formation of iron-silicide phases was observed between the Fe layer and Si substrate, and the silver and the silicon capping layer were also completely mixed with each other. In case of the Ag/Fe samples the silver moved to the sample surface through the iron layers, while iron shifted to the substrate and mixed with silicon.

HIV-positive people's clinic attendance for medication pick-up is critical for successful HIV treatment. However, limited evidence exists on it especially in low-income settings such as Nepal. Moreover, the role of family support in clinic attendance remains under-explored. Therefore, this study was conducted to examine the association between perceived family support and regular clinic attendance and to assess factors associated with regular clinic attendance for antiretroviral pills pick-up among HIV-positive individuals in Nepal. A cross-sectional study was conducted among 423 HIV-positive people in three districts of Nepal. Clinic attendance was assessed retrospectively for the period of 12 months. To assess the factors associated, an interview survey was conducted using a semi-structured questionnaire from July to August, 2015. Multiple logistic regression models were used to assess the factors associated with regular clinic attendance. Of 423 HIV-positive people, only 32.6% attended the clinics regularly. They were more likely to attend them regularly when they received high family support (AOR = 3.98, 95% CI = 2.29, 6.92), participated in support programs (AOR = 1.68, 95% CI = 1.00, 2.82), and had knowledge on the benefits of antiretroviral therapy (AOR = 2.62, 95% CI = 1.15, 5.99). In contrast, they were less likely to attend them regularly when they commuted more than 60 minutes to the clinics (AOR = 0.53, 95% CI = 0.30, 0.93), when they self-rated their health status as being very good (AOR = 0.13, 95% CI = 0.04, 0.44), good (AOR = 0.14, 95% CI = 0.04, 0.46), and fair (AOR = 0.21, 95% CI = 0.06, 0.70). HIV-positive individuals are more likely to attend the clinics regularly when they receive high family support, know the benefits of antiretroviral therapy, and participate in support programs. To improve clinic attendance, family support should be incorporated with HIV care programs in resource limited settings. Service providers should also consider

Social support has been shown to be a protective resource for mental health among chronically ill adults and caregiver populations. However, to date no known studies have quantitatively explored the relationship between social support and depression among women caring for children in HIV-endemic Southern Africa, although they represent a high risk population for mental health conditions. Using data from a household survey with 2,199 adult female caregivers of children, living in two resource-deprived high HIV-prevalence South African communities, we conducted hierarchical logistic regression analysis with interaction terms to assess whether social support had a main effect or stress-buffering effect on depression. Findings provide evidence of stress-buffering of non-HIV-related chronic illness, but not HIV-related illness. Results reinforce the importance of social support for the mental health of chronically ill caregivers, and suggest that factors related to the specific nature of HIV/AIDS may be hindering the potential stress-buffering effects of social support among people living with the disease. Implications for future research and interventions are discussed.

The monitoring of detailed 3-dimensional (3D) reactor core power distribution is a prerequisite in the operation of nuclear power reactors to ensure that various safety limits imposed on the LPD and DNBR, are not violated during nuclear power reactor operation. The LPD and DNBR should be calculated in order to perform the two major functions of the core protection calculator system (CPCS) and the core operation limit supervisory system (COLSS). The LPD at the hottest part of a hot fuel rod, which is related to the power peaking factor (PPF, F q ), is more important than the LPD at any other position in a reactor core. The LPD needs to be estimated accurately to prevent nuclear fuel rods from melting. In this study, support vector regression (SVR) and uncertainty analysis have been applied to estimation of reactor core power peaking factor

Refined shear correction factor for very thick simply supported and uniformly loaded isosceles right triangular auxetic plates

International Nuclear Information System (INIS)

Lim, Teik-Cheng

2016-01-01

For moderately thick plates, the use of First order Shear Deformation Theory (FSDT) with a constant shear correction factor of 5/6 is sufficient to take into account the plate deflection arising from transverse shear deformation. For very thick plates, the use of Third order Shear Deformation Theory (TSDT) is preferred as it allows the shear strain distribution to be varied through the plate thickness. Therefore no correction factor is required in TSDT, unlike FSDT. Due to the complexity involved in TSDT, this paper obtains a more accurate shear correction factor for use in FSDT of very thick simply supported and uniformly loaded isosceles right triangular plates based on the TSDT. By matching the maximum deflections for this plate according to FSDT and TSDT, a variable shear correction factor is obtained. Results show that the shear correction factor for the simplified TSDT, i.e. 14/17, is least accurate. The commonly adopted shear correction factor of 5/6 in FSDT is valid only for very thin or highly auxetic plates. This paper provides a variable shear correction for FSDT deflection that matches the plate deflection by TSDT. This variable shear correction factor allows designers to justify the use of a commonly adopted shear correction factor of 5/6 even for very thick plates as long as the Poisson’s ratio of the plate material is sufficiently negative.

Factors Considered by Elementary Teachers When Developing and Modifying Mathematical Tasks to Support Children's Mathematical Thinking

Science.gov (United States)

Fredenberg, Michael Duane

The idea that problems and tasks play a pivotal role in a mathematics lesson has a long standing in mathematics education research. Recent calls for teaching reform appeal for training teachers to better understand how students learn mathematics and to employ students' mathematical thinking as the basis for pedagogy (CCSSM, 2010; NCTM, 2000; NRC 1999). The teaching practices of (a) developing a task for a mathematics lesson and, (b) modifying the task for students while enacting the lesson fit within the scope of supporting students' mathematical thinking. Surprisingly, an extensive search of the literature did not yield any research aimed to identify and refine the constituent parts of the aforementioned teaching practices in the manner called for by Grossman and xiii colleagues (2009). Consequently, my research addresses the two questions: (a) what factors do exemplary elementary teachers consider when developing a task for a mathematics lesson? (b) what factors do they consider when they modify a task for a student when enacting a lesson? I conducted a multiple case study involving three elementary teachers, each with extensive training in the area of Cognitively Guided Instruction (CGI), as well as several years experience teaching mathematics following the principles of CGI (Carpenter et al., 1999). I recorded video of three mathematics lessons with each participant and after each lesson I conducted a semi-structured stimulated recall interview. A subsequent follow-up clinical interview was conducted soon thereafter to further explore the teacher's thoughts (Ginsberg, 1997). In addition, my methodology included interjecting myself at select times during a lesson to ask the teacher to explain her reasoning. Qualitative analysis led to a framework that identified four categories of influencing factors and seven categories of supporting objectives for the development of a task. Subsets of these factors and objectives emerged as particularly relevant when the

The role of psycho-social factors in the development of allergy was studied prospectively in 82 infants with a family history of atopy. The family participated in a standardized family test when the children were 18 months old. The ability to adjust to demands of the situation ('adaptability'), and the balance between emotional closeness and distance ('cohesion'), were assessed from videotapes by independent raters. Families rated as functional in both of these aspects were classified as 'functional', otherwise as 'dysfunctional'. The social network, life events, atopic symptoms (based on postal inquiries regarding symptoms answered by the parents, and on physical examinations), psychiatric symptoms, and socio-economic circumstances of the families were evaluated when the children were 18 months and 3 years of age. The children were classified as atopic (asthmatic symptoms or eczema) or as non-atopic. All but two children with atopic disease at 3 years of age had atopic disease before 18 months of age, while 32 of 60 children with atopic disease at 18 months of age had no problems by 3 years of age. An unbalanced family interplay at 18 months was associated with a relative risk (RR) of 1.99 for continuing atopic illness at 3 years of age (1.18 eczema on three or more localizations (RR reduced by 4.5%), and the amount of cat allergen in household dust (RR reduced by 3%). Recovery from atopic illness between 18 months and 3 years of age was four times as probable in families with functional interaction and a good social supportive network when children were 18 months of age, than in dysfunctional families with a poor social network (74% versus 20% p emotional distress than did healthy children (p = 0.02). Dysfunctional family interaction patterns were more commonly observed in families of children who at 3 years of age still had atopic symptoms, than in children who had recovered. The patterns included expression of emotion and reaction to the needs of others

The objectives of this study were to identify cultural factors (including acculturation and breastfeeding cultures in subjects' native countries and those in mainstream Taiwanese society) and social support related to breastfeeding among immigrant mothers in Taiwan. This study was a cross-sectional survey performed from October 2007 through January 2008. The study participants were 210 immigrant mothers living in Taipei City. The prevalence of exclusive and partial breastfeeding at 3 months postpartum was 59.0% and 14.3%, respectively. Logistic regression analysis revealed that breastfeeding experience among mothers-in-law and the perceived level of acceptance of breastfeeding in Taiwan were positively associated with breastfeeding at 3 months postpartum. Immigrant women with a higher level of household activity support were less likely to breastfeed. Immigrant mothers in Taiwan usually come from cultures with a higher acceptance level for breastfeeding; however, their breastfeeding practices are more likely to be influenced by the mainstream culture in Taiwan.

To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression models stratified by gender were fitted. Differences between men and women in prevalence of illegal drug use except non-prescription sedatives were observed. In both genders, less family support was associated with higher consumption of all drugs, except depressants, and with polyconsumption. To be studying and looking for work was related to cannabis and stimulant use and to polyconsumption among women, but only to cannabis use among men. These results support the notion that the start of university studies is a particularly relevant stage in the onset of illegal drug use and its prevention, and that consumption may be especially associated with family support.

To assess predictors of stated support for policies promoting physically active transportation. Cross-sectional. US counties selected on county-level physical activity and obesity health status. Participants completing random-digit dialed telephone survey (n = 906). Survey measures assessed stated support for 5 policies to promote physically active transportation, access to active transportation facilities, and time spent in a car. County-level estimates included household car dependence and funding for bicycle-pedestrian projects. Multivariable generalized linear mixed models using binary distribution and logit link, accounting for clustering within county. Respondents supported policies for accommodating bicyclists and pedestrians through street improvements (89%), school active transportation programs (75%), employer-funded active commuting incentives (67%), and allocation of public funding (68%) and tax support (56%) for building and maintaining public transit. Residents spending >2 h/d (vs public transit (OR: 1.85; CI: 1.24-2.77) improvements. Residents in counties investing >$1.6 million in bicycle and pedestrian improvements expressed greater support for funding (OR: 1.71; CI: 1.04-2.83) and tax increases (OR: 1.73; CI: 1.08-2.75) for transit improvements compared to those with lower prior investments (transportation is higher where relevant investments in active transportation infrastructure are large (>$1.6 M), public transit is nearby, and respondents drive >2 h/d.

A cross-sectional study design was applied amongst a random sample (n = 10158) of Chinese adolescents. Self-completed questionnaires, including demographic characteristics, Internet use situation, Youth Internet Addiction Test, Youth Social Support Rating Scale and Zung Self-rating Depression Scale were utilized to examine the study objectives. Among the study population, the prevalence rate of Internet addiction was 10.4%, with 1038 (10.2%) moderately and 21 (0.2%) severely addicted to the Internet. Results from the multivariate logistic regression analyses suggested that a variety of related factors have significant effects on Internet addiction (parental control, per capita annual household income, academic performance, the access to Internet, online activities). The correlation coefficients showed that Internet addiction was negatively correlated with social support and positively associated with depression. Social support had a significant negative predictive effect on Internet addiction. The mediating effect of depression between social support and Internet addiction was remarkable.

Parents of disabled children often seek support from their peers. The shared experience between parents appears to be a crucial mediating factor. Understanding how a sense of shared experience is fostered can help to design and evaluate services that seek to provide peer support. We carried out a qualitative study involving semi-structured interviews and focus groups. Participants were 12 parents and 23 befrienders who had contact with the Face2Face one-to-one befriending service in Devon and Cornwall during a 12-month period, and 10 professionals from health, social care and education. Formal structures and processes in place such as training and ongoing supervision and support were highly valued as was the highly personalized, confidential, flexible, one-to-one at-home nature of the service. Crucial to establishing rapport was putting the right people together and ensuring a good match between befrienders and parents. Clearly, the befriending parent has to be emotionally prepared to provide help. However, if the parent being offered support was not ready to accept help at the time it was offered or the type of support was not right for them, they are less likely to engage with the service. Organizational and process factors as well as characteristics of the parents offering and receiving support contribute to the sense of shared experience in one-to-one peer support. These factors interact to influence whether peer support is effective and should be explicitly considered when designing and evaluating services. © 2015 John Wiley & Sons Ltd.

To examine the factor structure and to evaluate the longitudinal measurement invariance of the demand-control-support questionnaire (DCSQ), using the Swedish Longitudinal Occupational Survey of Health (SLOSH). A confirmatory factor analysis (CFA) and multi-group confirmatory factor analysis (MGCFA) models within the framework of structural equation modeling (SEM) have been used to examine the factor structure and invariance across time. Four factors: psychological demand, skill discretion, decision authority and social support, were confirmed by CFA at baseline, with the best fit obtained by removing the item repetitive work of skill discretion. A measurement error correlation (0.42) between work fast and work intensively for psychological demands was also detected. Acceptable composite reliability measures were obtained except for skill discretion (0.68). The invariance of the same factor structure was established, but caution in comparing mean levels of factors over time is warranted as lack of intercept invariance was evident. However, partial intercept invariance was established for work intensively. Our findings indicate that skill discretion and decision authority represent two distinct constructs in the retained model. However removing the item repetitive work along with either work fast or work intensively would improve model fit. Care should also be taken while making comparisons in the constructs across time. Further research should investigate invariance across occupations or socio-economic classes.

Held, Mary L

2018-04-01

Latino immigrants encounter considerable stressors that pose risks to health and well-being during settlement in the USA. Social support serves as a protective factor that can help to buffer the negative effects of stress. Despite the importance of social support, we know little about how Latino immigrants differentially experience this protective factor. The current study analyzed data from 100 Latino immigrants residing in Tennessee. Hierarchical multiple regression analysis was employed to examine variation in self-reported social support by immigrant characteristics and immigration-related factors. Females, immigrants who are not married/cohabitating, and those who reported experiencing a greater number of discrete stressors in the USA each reported lower levels of social support. Implications for practice include an increased emphasis on assessing levels of social support and designing services to strengthen support for the most vulnerable immigrants. Future research should consider a longitudinal analysis and specific types of social support.

Studies using the Supportive Care Needs Survey (SCNS) report high levels of unmet supportive care needs (SCNs) in psychological and less-so physical & daily living domains, interpreted as reflecting disease/treatment-coping deficits. However, service and culture differences may account for unmet SCNs variability. We explored if service and culture differences better account for observed SCNs patterns. Hong Kong (n = 180), Taiwanese (n = 263) and Japanese (n = 109) CRC patients' top 10 ranked SCNS-34 items were contrasted. Mean SCNS-34 domain scores were compared by sample and treatment status, then adjusted for sample composition, disease stage and treatment status using multivariate hierarchical regression. All samples were assessed at comparable time-points. SCNs were most prevalent among Japanese and least among Taiwanese patients. Japanese patients emphasized Psychological (domain mean = 40.73) and Health systems and information (HSI) (38.61) SCN domains, whereas Taiwanese and Hong Kong patients emphasized HSI (27.41; 32.92) and Patient care & support (PCS) (19.70; 18.38) SCN domains. Mean Psychological domain scores differed: Hong Kong = 9.72, Taiwan = 17.84 and Japan = 40.73 (pcultural influences, age and occupation differences, and less so clinical factors, differentially account for significant variation in published studies of SCNs.

Full Text Available Abstract Background The Chinese tradition of filial piety, which prioritized family-based care for the elderly, is transitioning and elders can no longer necessarily rely on their children. The purpose of this study was to identify community support for the elderly, and analyze the factors that affect which model of old-age care elderly people dwelling in communities prefer. Methods We used the database “Health and Social Support of Elderly Population in Community”. Questionnaires were issued in 2013, covering 3 districts in Beijing. A group of 1036 people over 60 years in age were included in the study. The respondents’ profile variables were organized in Andersen’s Model and community healthcare resource factors were added. A multinomial logistic model was applied to analyze the factors associated with the desired aging care models. Results Cohabiting with children and relying on care from family was still the primary desired aging care model for seniors (78 %, followed by living in institutions (14.8 % and living at home independently while relying on community resources (7.2 %. The regression result indicated that predisposing, enabling and community factors were significantly associated with the aging care model preference. Specifically, compared with those who preferred to cohabit with children, those having higher education, fewer available family and friend helpers, and shorter distance to healthcare center were more likely to prefer to live independently and rely on community support. And compared with choosing to live in institutions, those having fewer available family and friend helpers and those living alone were more likely to prefer to live independently and rely on community. Need factors (health and disability condition were not significantly associated with desired aging care models, indicating that desired aging care models were passive choices resulted from the balancing of family and social caring resources

Analysis Of Factors Affecting Gravity-Induced Deflection For Large And Thin Wafers In Flatness Measurement Using Three-Point-Support Method

Directory of Open Access Journals (Sweden)

Liu Haijun

2015-12-01

Full Text Available Accurate flatness measurement of silicon wafers is affected greatly by the gravity-induced deflection (GID of the wafers, especially for large and thin wafers. The three-point-support method is a preferred method for the measurement, in which the GID uniquely determined by the positions of the supports could be calculated and subtracted. The accurate calculation of GID is affected by the initial stress of the wafer and the positioning errors of the supports. In this paper, a finite element model (FEM including the effect of initial stress was developed to calculate GID. The influence of the initial stress of the wafer on GID calculation was investigated and verified by experiment. A systematic study of the effects of positioning errors of the support ball and the wafer on GID calculation was conducted. The results showed that the effect of the initial stress could not be neglected for ground wafers. The wafer positioning error and the circumferential error of the support were the most influential factors while the effect of the vertical positioning error was negligible in GID calculation.

Ventilator-associated pneumonia (VAP) is frequent in Intensive Care Unit (ICU) patients. In the specific case of patients treated with Veno-Arterial Extracorporeal Membrane Oxygenation Support (VA-ECMO), VAP treatment failures (VAP-TF) have been incompletely investigated. To investigate the risk factors of treatment failure (VAP-TF) in a large cohort of ICU patients treated with VA-ECMO, we conducted a retrospective study in a Surgical ICU about patients assisted with VA-ECMO between January 1, 2013, and December 31, 2014. Diagnosis of VAP was confirmed by a positive quantitative culture of a respiratory sample. VAP-TF was defined as composite of death attributable to pneumonia and relapse within 28 days of the first episode. In total, 152 patients underwent ECMO support for > 48h. During the VA-ECMO support, 85 (55.9%) patients developed a VAP, for a rate of 60.6 per 1000 ECMO days. The main pathogens identified were Pseudomonas aeruginosa and Enterobacteriaceae. VAP-TF occurred in 37.2% of patients and was associated with an increased 28-day mortality (Hazard Ratio 3.05 [1.66; 5.63], P<0.001), and VA-ECMO assistance duration (HR 1.47 [1.05-2.05], P = 0.025). Risk factors for VAP-TF were renal replacement therapy (HR 13.05 [1.73; 98.56], P = 0.013) and documentation of Pseudomonas aeruginosa (HR 2.36 [1.04; 5.35], P = 0.04). VAP in patients treated with VA-ECMO is associated with an increased morbidity and mortality. RRT and infection by Pseudomonas aeruginosa appear as strong risks factors of treatment failure. Further studies seem necessary to precise the best antibiotic management in these patients.

The psychometric properties of the Multidimensional Scale of Perceived Social Support (MSPSS) of the Urdu (MSPSS-U) and Nepali (MSPSS-N) versions were investigated among Pakistani (n=148) and Nepalese (n=153) respondents living in Hong Kong. The factor analysis of the MSPSS-N conducted in this study confirmed the three factors of the original MSPSS, namely, Family, Friend, and Significant Others, while only two factors were extracted from the MSPSS-U (i.e., the Family and Friends subscales). With regard to construct validity, both the MSPSS-U and MSPSS-N were inversely correlated with depression, anxiety and stress as assessed by the Depression Anxiety Stress Scale (DASS-21). The internal reliability and construct validity of the MSPSS-U and MSPSS-N were also established and provided support for the validity of both versions as tools for measuring perceived social support among South Asian migrants.

Full Text Available The overview and theoretical study of social support for children and adolescents is presented. The issues of social development of children and adolescents in terms of Bronfenbrenner’s ecological systems theory and Kahn’s and Antonucci’s Convoy Model of Social Relations are discussed. The sources, forms and types of social support for the early, pre-school, primary school and adolescents are analyzed. The paper specifies the following issues: the parent-child relationships and characteristics of social support in early childhood can affect the development of the structure and quality of human social relations network throughout his/her life. Social networks and the organization of social support for adolescents are detailed. The patterns of social support of adolescents may affect their psychosocial well-being. The social support systems used by modern adolescents are described. The controversial issues of seeking social support as the leading coping strategy are raised. Various ways of seeking social support for adolescence are analyzed. The importance of parents, teachers and peers in providing social support for children and adolescents is shown. The author’s view of social support as one of the resources of the child’s autonomy, which can be developed only in certain respects, i.e. respect for personal boundaries and accepting differences in individual values and needs, the independence aspiration supported by respect and interest, unpunished by shame or the threat of rejection.

Using representative survey data of Filipino Americans in Honolulu and San Francisco (SF) (N = 2,259), we examined the roles of emotional support and instrumental support on gambling participation. With considerable difference in gambling environments between two regions, we conducted two sets of hierarchical regression analyses for Honolulu sample, which has restricted gambling laws, and SF sample, which has legal gambling environment, and compared the effects of two types of social support on gambling participation. The results indicated that emotional support was positively and instrumental support was negatively associated with gambling participation among Filipino Americans in Honolulu. However, neither type of social support was significantly associated with gambling participation among Filipino Americans living in SF. This study highlights the differing roles and effects of instrumental and emotional support on gambling where gambling is restricted. It also suggests that gambling behaviors of Filipino Americans are subject to situation- and environment-specific factors.

Community factors supporting child mental Health.

Science.gov (United States)

Earls, F

2001-10-01

A principal purpose of this article has been to examine the gap between research and practice in relation to community factors in child mental health. Two caveats were introduced in preparation for this assessment. First, it was pointed out that the definition of communities has been expanded by considering the organizing properties of social aggregates that are not simply a function of the race, ethnicity, or social class of individuals who compose them. Having these definitions grounded in theory substantially advances the needs of research and the design and goals of community-level interventions. The second caveat relates to the boundaries of the disciplines that cater to the needs of children. During the same era when child psychiatry is largely occupied with placing psychotropic medications at the center of clinical approaches, there is an important effort in child psychology and sociology to cut across their disciplinary confines to form more comprehensive designs that are sensitive to experiences and circumstances that emerge from specific aspects of community context. Research from the PHDCN was used as an example of this new interdisciplinary approach. Several community-based research projects were selected for review based on their clear implications to improve context-sensitive assessment of child mental health and design effective community-based interventions to improve child mental health. The Healthy Start and CATCH programs indicate that involving child professionals at the grassroots of community life requires skill and patience but that the effort is satisfying and potentially effective. Other examples, exemplified by North Carolina's Smart Start initiative and the program of developmental assets from the Search Institute, demonstrate coherent approaches that provide a foundation for long-term capacity building in assessment, local decision making, and the design and evaluation of interventions. Three conclusions are warranted from this

To examine the amount of support being provided by nurses to women during childbirth and factors that influence the provision of support. Exploratory, descriptive. Work sampling method was used to determine the percentage of time nurses spend in supportive care activities. Twelve nurses were observed over six nonconsecutive day shifts on a birthing unit of a Canadian teaching hospital in Quebec. A total of 404 observations were made. Nurses were also interviewed to determine their perceptions of what constitutes supportive nursing care and the factors that facilitate or inhibit the provision of this care. Nurses spent only 12.4% of their total time providing supportive care to laboring women. Interviews with nurses suggested that perceptions of the components of supportive care were comparable to this study's operational definition of support, namely: physical, emotional, and instructional/informational support and advocacy. Barriers to providing support identified by nurses included lack of time and insufficient staff. However, further content analysis of the interview data revealed that healthcare providers had a pervasive sense of control over laboring women and their partners. Although nursing support has been identified as an important aspect of nursing care in childbirth, this study demonstrated an incongruity between what nurses perceived as being supportive care and the amount of support that was actually provided. Barriers to the provision of supportive care in the practice setting as well as suggestions for its enhancement are discussed.

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

The relationship between postnatal depression, sociodemographic factors, levels of partner support, and levels of physical activity

Full Text Available Background: postnatal depression (PND is defined as a psychological mood disorder that occurs in a mother within six weeks of her giving birth. It refers to an episode that causes mood disturbance and it could begin in, or extend into, the postpartum period. It is thought to have a high impact upon the mother’s health as well as the family’s functioning and the child’s development. Socio-demographic, psych-social, and physical activity factors may all contribute to postpartum mood and ability to cope with responsibilities. The primary aim of this study was to determine which of these factors predicted PND in postpartum women. A secondary aim was to identify the socio-demographic and psycho-social predictors of physical activity in postpartum women . Methods: The study used a cross-sectional correlational design. A sample of 150 postpartum women was sent a package of six standardised questionnaires. Results: There was no association between physical activity and PND; however, older mothers, mothers of younger children, mothers who are less reluctant to ask for help, and mothers who are more satisfied with the help they get experience lower levels of PND. Mothers of older babies, mothers with more children, and less educated mothers are more likely to engage in caregiving activities, whereas mothers with fewer children and higher levels of partner support are more likely to engage in occupational activities. None of the socio-demographic factors or any of the parenting factors predicted levels of sporting activity.

HIV/AIDS, a chronic burden in Ghana, poses social and health outcome concerns to those infected. Examining the Medical Outcome Study Social Support Survey (MOS-SSS) instrument among 300 Ghanaians from a cross-sectional design, Principal Component Analysis yielded four factors (positive interaction, trust building, information giving, and essential support), which accounted for 85.73% of the total variance in the MOS-SSS. A logistic regression analysis showed that essential support was the strongest predictor of the length of time an individual stayed in the support group, whereas positive interaction indicated negative association. The study's implications for policy, research, and practice were discussed.

Inadequate social support is an important determinant of postpartum depression (PPD). Social support for pregnant women consists of supports from various sources and can be measured at different gestation periods. Differentiating the effects of social support from different sources and measured at different gestation periods may have important implications in the prevention of PPD. In the family centred Chinese culture, family support is likely to be one of the most important components in social support. The aim of this study was to assess the association of prenatal family support and postnatal family support with PPD. A prospective cohort study was conducted between February and September 2007 in Hunan, China. Family support was measured with social support rating scale at 30-32 weeks of gestation (prenatal support) and again at 2 weeks of postpartum visit (postnatal support). PPD was defined as Edinburgh Postnatal Depression Scale (EPDS) score > or =13. A total of 534 pregnant women were included, and among them, 103 (19.3%) scored 13 or more on the EPDS. PPD was 19.4% in the lowest tertile versus 18.4% in the highest quartile (adjusted odds ratio: 1.04, 95% confidence interval 0.60, 1.80) for prenatal support from all family members, and PPD was 39.8% in the lowest tertile versus 9.6% in the highest tertile (adjusted odds ratio: 4.4, 95% confidence interval 2.3, 8.4) for postnatal support from all family members. Among family members, support from husband had the largest impact on the risk of developing PPD. Lack of postnatal family support, especially the support from husband, is an important risk factor of PPD.

Vestibular factors influencing the biomedical support of humans in space.

Lichtenberg, B K

1988-01-01

This paper will describe the biomedical support aspects of humans in space with respect to the vestibular system. The vestibular system is thought to be the primary sensory system involved in the short-term effects of space motion sickness although there is increasing evidence that many factors play a role in this complex set of symptoms. There is the possibility that an individual's inner sense of orientation may be strongly coupled with the susceptibility to space motion sickness. A variety of suggested countermeasures for space motion sickness will be described. Although there are no known ground-based tests that can predict space motion sickness, the search should go on. The long term effects of the vestibular system in weightlessness are still relatively unknown. Some preliminary data has shown that the otoconia are irregular in size and distribution following extended periods of weightlessness. The ramifications of this data are not yet known and because the data was obtained on lower order animals, definitive studies and results must wait until the space station era when higher primates can be studied for long durations. This leads us to artificial gravity, the last topic of this paper. The vestibular system is intimately tied to this question since it has been shown on Earth that exposure to a slow rotating room causes motion sickness for some period of time before adaptation occurs. If the artificial gravity is intermittent, will this mean that people will get sick every time they experience it? The data from many astronauts returning to Earth indicates that a variety of sensory illusions are present, especially immediately upon return to a 1-g environment. Oscillopsia or apparent motion of the visual surround upon head motion along with inappropriate eye motions for a given head motion, all indicate that there is much to be studied yet about the vestibular and CNS systems reaction to a sudden application of a steady state acceleration field like 1-g.

Highlights: • Ag-loaded Fe 3 O 4 @C nanospheres were synthesized by a facile method. • The Fe 3 O 4 encapsulated mesoporous carbon was decorated with 10 nm Ag nanocrystals. • The as-prepared Ag-Fe 3 O 4 @C nanocomposite showed excellent catalytic activity. • The nanocomposite had convenient magnetic separability. - Abstract: A novel approach for the synthesis of Ag-loaded Fe 3 O 4 @C nanospheres (Ag-Fe 3 O 4 @C) was successfully developed. The catalysts possessed a carbon-coated magnetic core and grew active silver nanoparticles on the outer shell using hydrazine monohydrate as the AgNO 3 reductant in ethanol. The morphology, inner structure, and magnetic properties of the as-prepared composites were studied with transmission electron microscopy (TEM), X-ray powder diffraction (XRD), fourier translation infrared spectroscopy (FT-IR), and vibrating sample magnetometer (VSM) techniques. Catalytic activity was investigated by degrading rhodamine B (RhB) in the designed experiment. The obtained products were monodispersed and bifunctional with high magnetization, as well as exhibited excellent catalytic activity toward organic dye with 98% of RhB conversion within 20 min in the presence of NaBH 4 . The product also exhibited convenient magnetic separability and maintained high catalytic activity after six cycle runs

Full Text Available PANI-Ag-Fe nanocomposite thin films based electrochemical E. coli sensor was developed with thermal annealing. PANI-Ag-Fe nanocomposite thin films were prepared by oxidative polymerization of aniline and the reduction process of Ag-Fe bimetallic compound with the presence of nitric acid and PVA. The films were deposited on glass substrate using spin-coating technique before they were annealed at 300°C. The films were characterized using XRD, UV-Vis spectroscopy, and FESEM to study the structural and morphological properties. The electrochemical sensor performance was conducted using I-V measurement electrochemical impedance spectroscopy (EIS. The sensitivity upon the presence of E. coli was measured in clean water and E. coli solution. From XRD analysis, the crystallite sizes were found to become larger for the samples after annealing. UV-Vis absorption bands for samples before and after annealing show maximum absorbance peaks at around 422 nm–424 nm and 426 nm–464 nm, respectively. FESEM images show the diameter size for nanospherical Ag-Fe alloy particles increases after annealing. The sensor performance of PANI-Ag-Fe nanocomposite thin films upon E. coli cells in liquid medium indicates the sensitivity increases after annealing.

Pipe supports and anchors - LMFBR applications

Anderson, M.J.

1983-06-01

Pipe design and support design can not be treated as separate disciplines. A coordinated design approach is required if LMFBR pipe system adequacy is to be achieved at a reasonable cost. It is particularly important that system designers understand and consider those factors which influence support train flexibility and thus the pipe system dynamic stress levels. The system approach must not stop with the design phase but should continue thru the erection and acceptance test procedures. The factors that should be considered in the design of LMFBR pipe supports and anchors are described. The various pipe support train elements are described together with guidance on analysis, design and application aspects. Post erection acceptance and verification test procedures are then discussed

2016-01-01

Study context: This paper is the third paper arising from a two year long, in-depth case study exploring various components of the role of consultant radiographers in the UK. This paper focuses particularly upon the perceived impact of the role and factors that support and hinder the role in practice. Methods: A longitudinal case study method was used to explore the role of consultant radiographers. Interviewing was informed and guided by a phenomenological approach to promote a deeper understanding of consultants' experiences in the role. Eight consultant radiographers participated, with six involved throughout the whole study. Over an 18 month period each of those six consultants was interviewed three times. Two consultants only participated in the first interview; these interviews are also reported here. A total of 20 interviews were conducted. Findings: Interviews explored the impact of the consultant role as perceived by consultants themselves, and encouraged individual reflection on factors which had both supported and hindered success therein. Analysis demonstrated that there was substantial variation in the experiences communicated yet, and without any exception, all consultants reported that the introduction of their role had been beneficial to service delivery and quality of patient care. A number of obstacles were outlined, as well as a range of support mechanisms. Recommendations are thus made as to how the consultant role might be more effectively supported in the future. - Highlights: • The perceived impact of the consultant radiographer role in practice. • Reflections upon what supported the consultants in their role. • Reflections upon what hindered the consultants in their role.

2011-08-01

The purpose of this article is to investigate the need for ethics support in Dutch healthcare institutions in order to understand why ethics support is often not used in practice and which factors are relevant in this context. This study had a mixed methods design integrating quantitative and qualitative research methods. Two survey questionnaires, two focus groups and 17 interviews were conducted among board members and ethics support staff in Dutch healthcare institutions. Most respondents see a need for ethics support. This need is related to the complexity of contemporary healthcare, the contribution of ethics support to the core business of the organisation and to the surplus value of paying structural attention to ethical issues. The need for ethics support is, however, not unconditional. Reasons for a lacking need include: aversion of innovations, negative associations with the notion of ethics support service, and organisational factors like resources and setting. There is a conditioned need for ethics support in Dutch healthcare institutions. The promotion of ethics support in healthcare can be fostered by focusing on formats which fit the needs of (practitioners in) healthcare institutions. The emphasis should be on creating a (culture of) dialogue about the complex situations which emerge daily in contemporary healthcare practice.

The Flip Side of the Attrition Coin: Faculty Perceptions of Factors Supporting Graduate Student Success

Directory of Open Access Journals (Sweden)

Joanna A Gilmore

2016-12-01

Full Text Available Doctoral attrition consistently hovers around 50% with relevant literature identifying several mediating factors, including departmental culture, student demographics, and funding. To advance this literature, we interviewed 38 graduate faculty advisors in science, engineering, or mathematics disciplines at a research-extensive university to capture their perceptions of factors supporting graduate student success. Using a constant-comparison method, we found that faculty perceptions aligned within three major categories, termed: motivated student behaviors, formative student learning experiences, and essential student knowledge and skills. Student motivation was most prominently represented in findings. This aligns with prior studies showing that faculty tend to identify the cause of graduate student failure as lying within the students themselves and rarely discuss their role or the department’s contribution to attrition. Thus findings offer an opportunity to reflect and improve upon practice. The study also highlights actions graduate students can take to increase success, such as developing collegial relationships and early involvement in research and scholarly writing. We encourage graduate faculty advisors and others to identify ways to help graduate students overcome common obstacles to enduring and succeeding within graduate programs. Faculty perceptions are also examined by discipline and faculty rank, and directions for future research are offered.

Uncovering the factors that can support and impede post-disaster EIA practice in developing countries: The case of Aceh Province, Indonesia

The close relationship between environmental degradation and the occurrence and severity of disaster events has in recent years raised the profile of environmental assessment (EA) in the disaster management field. EA has been identified as a potentially supportive tool in the global effort to reduce disaster risk. As a component of this, attention has been brought specifically to the importance of the application of EA in the aftermath of disaster events in order to help prevent recurrence and promote sustainability. At the same time, however, it has also been recognised that post-disaster environments may be unfavourable to such practices. Looking at the practice of environmental impact assessment (EIA), this paper reports on a study which sought to identify more specifically the factors which can both support and hinder such practice following disaster events in a developing country context. Analysing the situation in Aceh Province, Indonesia, after the impact of two tsunamigenic earthquakes in late 2004 and early 2005, it is concluded that if EIA is to have a central role in the post-disaster period, pre-disaster preparation could be a key. -- Highlights: • Close relationship between environmental degradation and occurrence/severity of disaster events has raised profile of EA. • EA as a potentially supportive tool in the global effort to reduce disaster risk • Application of EA in the aftermath of disaster events to help prevent recurrence and promote sustainability • The paper looks at factors which can both support and hinder EA following disaster events in a developing country context. • We analyse the situation in Aceh Province, Indonesia, after the impact of two tsunamigenic earthquakes in 2004 and 2005.

The Role of Organisational Phenomena in Software Cost Estimation: A Case Study of Supporting and Hindering Factors

2018-01-01

Full Text Available Despite the fact that many researchers and practitioners agree that organisational issues are equally important as technical issues from the software cost estimation (SCE success point of view, most of the research focus has been put on the development of methods, whereas organisational factors have received surprisingly little academic scrutiny. This study aims to identify organisational factors that either support or hinder meaningful SCE, identifying their impact on estimation success. Top management’s role is specifically addressed. The study takes a qualitative and explorative case study based approach. In total, 18 semi-structured interviews aided the study of three projects in three organisations. Hence, the transferability of the results is limited. The results suggest that the role of the top management is important in creating prerequisites for meaningful estimation, but their day-to-day participation is not required for successful estimation. Top management may also induce undesired distortion in estimation. Estimation maturity and estimation success seem to have an interrelationship with software process maturity, but there seem to be no significant individual organisational factors, which alone would make estimation successful. Our results validate several distortions and biases reported in the previous studies, and show the SCE research focus has remained on methodologies and technical issues.

Greater social support is predictive of lower depression and higher quality of life (QOL). However, the way in which social support is provided has changed greatly with the expanding role of social networking sites (e.g., Facebook). While there are numerous anecdotal accounts of the benefits of Facebook-based social support, little empirical evidence exists to support these assertions, and there are no empirically validated measures designed to assess social support provided via this unique social networking medium. This study sought to develop an empirically sound measure of Facebook-based social support (Facebook Measure of Social Support [FMSS]) and to assess how this new measure relates to previously established measures of support and two outcome variables: depression and QOL. Following exploratory factor analysis, the FMSS was determined to assess four factors of social support on Facebook (Perceived, Emotional, Negative, Received/Instrumental). The Negative Support factor on the FMSS was most strongly related to both depression and QOL with magnitudes (and direction of relationships) comparable to a traditional measure of perceived social support. However, two FMSS factors (Received/Instrumental and Perceived) were unrelated to both mental health outcomes. Contrary to expectations, elevations in one FMSS factor (Emotional) was associated with worse symptoms of depression and poorer psychological QOL. When taken together, only the absence of negative social support on Facebook is significantly predictive of mental health functioning. Consequently, those hoping to use Facebook as a medium for reducing depression or improving QOL are unlikely to realize significant therapeutic benefits.

With the gradual maturity of the real estate market in China, urban housing prices are also better able to reflect changes in market demand and the commodity property of commercial housing has become more and more obvious. Many scholars in our country have made a lot of research on the factors that affect the price of commercial housing in the city and the number of related research papers increased rapidly. These scholars’ research results provide valuable wealth to solve the problem of urban housing price changes in our country. However, due to the huge amount of literature, the vast amount of information is submerged in the library and cannot be fully utilized. Text mining technology has been widely concerned and developed in the field of Humanities and Social Sciences in recent years. But through the text mining technology to obtain the influence factors on the price of urban commercial housing is still relatively rare. In this paper, the research results of the existing scholars were excavated by text mining algorithm based on support vector machine in order to further make full use of the current research results and to provide a reference for stabilizing housing prices.

Full Text Available Research has commonly suggested that adequate and appropriate mentoring and faculty perception of support for a work-life balance are important factors in the recruitment, development, and retention of university faculty. To better understand the role of these factors in faculty job performance at teaching universities, faculty from such a university were surveyed about their experiences with these forms of support and the factors that influenced their perception of the ability to do their job well. Results indicate that faculty mentoring was an important predictor for support at the department level. Additionally, perceived work-life balance was a significant factor at the college and university levels.

Similar goals, divergent motives. The enabling and constraining factors of Russia's capacity-based renewable energy support scheme

International Nuclear Information System (INIS)

Smeets, Niels

2017-01-01

In 2009, the Russian government set its first quantitative renewable energy target at 4.5% of the total electricity produced and consumed by 2020. In 2013, the Government launched its capacity-based renewable energy support scheme (CRESS), however, the expects it will merely add 0.3% to the current 0.67% share of renewables (Ministry of Energy, 2016c). This raises the question what factors might explain this implementation gap. On the basis of field research in Moscow, the article offers an in-depth policy analysis of resource-geographic, financial, institutional and ecologic enabling and constraining factors of Russia's CRESS between 2009 and 2015. To avoid the trap that policy intentions remain on paper, the entire policy cycle – from goal setting to implementation – has been covered. The article concludes that wind energy, which would have contributed the lion's share of new renewable energy capacity, lags behind, jeopardizing the quantitative renewable energy target. The depreciation of the rouble decreased return on investment, and the Local Content Requirement discouraged investors given the lack of Russian wind production facilities. Contrary to resource-geographic and financial expectations, solar projects have been commissioned more accurately, benefitting from access to major business groups and existing production facilities. - Highlights: • The support scheme is focused on the oversupplied integrated electricity market. • The scheme disregards the technical and economic potential in isolated areas. • The solar industry develops at the fastest rate, wind and small hydro lag behind. • Access to business groups and production facilities condition implementation. • The devaluation of the rouble necessitated a revision of the policy design.

Depression and intimate partner violence (IPV) are significant health issues for U.S. women. Interaction effects between IPV and other psychosocial factors on the severity of depressive symptoms have not been fully explored. This study assessed effect modification, that is, how IPV interacts with sociodemographics, psychosocial factors and health risk behaviors, on the severity of depressive symptoms in women. We utilized cross-sectional data from female respondents (n = 16,106) of the 2006 Behavioral Risk Factors Surveillance Survey. Sociodemographics, psychosocial variables, and health risk behaviors determined to be significantly associated with depression were tested for interaction effects with IPV. Weighted ordinal logistic regression and predicted probabilities illustrated the effect of IPV status on depressive symptom severity, stratified by interaction effects. Recent and lifetime IPV exposure were associated with more severe depressive symptoms compared with no IPV exposure. IPV history interacted with employment status and social support on the severity of depressive symptoms in women. Overall, any IPV exposure was associated with more severe depressive symptoms among women with low social support and unemployment, although the effect of recent (versus lifetime) IPV was most pronounced among women with high social support or employed women. Social support and employment status interact with IPV on the severity of depressive symptoms in women. Therefore, social support or workplace interventions designed to improve depressive symptoms should examine IPV history. Copyright © 2014 Jacobs Institute of Women's Health.

Activation of 125I-Factor IX and 125I-Factor X: Effect of tissue factor and Factor VII, Factor Xsub(a) and thrombin

International Nuclear Information System (INIS)

Oesterud, B.; Rapaport, S.I.

Activation of Factor IX and Factor X was studied by adding 125 I-Factor IX or 125 I-Factor X to reaction mixtures and quantitating cleavage products by reduced sodium dodecylsulfate gel electrophoresis. Thrombin failed to activate Factors IX or X; Factor Xsub(a) produced insignificant amounts of cleavage products of both factors. In contrast, the reaction product of tissue factor and Factor VII cleaved large amounts of both Factor IX and Factor X in purified systems and in plasma. In incubation mixtures of plasma containing added 125 I-Factor IX or 125 I-Factor X, tissue factor and Ca 2+ ions, the percentage of total radioactivity in the heavy chain peak of 125 I-IXsub(a) and the heavy chain of 125 I-Xsub(a) increased at a similar rate. When the tissue factor was diluted, similar curves were obtained for percent cleavage of 125 I-Factor IX and percent cleavage of 125 I-Factor X plotted against tissue factor concentration. These findings support the hypothesis that activation of Factor IX by the tissue factor-Factor VII reaction product represents a physiologically significant step in normal haemostasis. (author)

In addition, it is debatable whether the progress in survival is attributable simply to the therapy used to destroy the tumor clone or if it is also because of therapy designed to ameliorate disease complications. Supportive therapy has evolved greatly alongside general supportive measures used in hematologic malignancies (such as new antibiotics, antifungal agents, and growth factors) in addition to better indications in complementary treatments such as radiotherapy, dialysis, and surgery. However, in MM, several specific adjuvant therapies have also been introduced (eg, bisphosphonates and erythroid-stimulating factors), which have conferred a key role to supportive therapy in the general treatment of patients with MM.

Full Text Available Abstract Background In recent years, there have been numerous initiatives undertaken to describe critical information needs related to the collection, management, analysis, and dissemination of data in support of biomedical research (J Investig Med 54:327-333, 2006; (J Am Med Inform Assoc 16:316–327, 2009; (Physiol Genomics 39:131-140, 2009; (J Am Med Inform Assoc 18:354–357, 2011. A common theme spanning such reports has been the importance of understanding and optimizing people, organizational, and leadership factors in order to achieve the promise of efficient and timely research (J Am Med Inform Assoc 15:283–289, 2008. With the emergence of clinical and translational science (CTS as a national priority in the United States, and the corresponding growth in the scale and scope of CTS research programs, the acuity of such information needs continues to increase (JAMA 289:1278–1287, 2003; (N Engl J Med 353:1621–1623, 2005; (Sci Transl Med 3:90, 2011. At the same time, systematic evaluations of optimal people, organizational, and leadership factors that influence the provision of data, information, and knowledge management technologies and methods are notably lacking. Methods In response to the preceding gap in knowledge, we have conducted both: 1 a structured survey of domain experts at Academic Health Centers (AHCs; and 2 a subsequent thematic analysis of public-domain documentation provided by those same organizations. The results of these approaches were then used to identify critical factors that may influence access to informatics expertise and resources relevant to the CTS domain. Results A total of 31 domain experts, spanning the Biomedical Informatics (BMI, Computer Science (CS, Information Science (IS, and Information Technology (IT disciplines participated in a structured surveyprocess. At a high level, respondents identified notable differences in theaccess to BMI, CS, and IT expertise and services depending on the

Support groups are an important resource for many people living with rare diseases. The perceived benefits of participating in support groups for people with rare diseases and factors that may influence the ability to successfully establish and maintain these groups are not well understood. Thus, the objective of this scoping review was to provide a mapping of the available evidence on the (1) benefits or perceived benefits of participating in rare disease support groups and (2) barriers and facilitators of establishing and maintaining these groups. CINAHL and PubMed were searched from January 2000 to August 2015, with no language restrictions. Publications that described the benefits or perceived benefits of participating in rare disease support groups or the barriers and facilitators of establishing and maintaining them were eligible for inclusion. Two investigators independently evaluated titles/abstracts and full-text publications for eligibility, and extracted data from each included publication. Ten publications were included in the scoping review. There was no trial evidence on support group benefits. All ten publications reported on the perceived benefits of participating in rare disease support groups. Three reported on barriers and facilitators of establishing and maintaining them. Overall, seven different perceived benefits of participating in rare disease support groups were identified: (1) meeting and befriending other people with the same rare disease and similar experiences; (2) learning about the disease and related treatments; (3) giving and receiving emotional support; (4) having a place to speak openly about the disease and one's feelings; (5) learning coping skills; (6) feeling empowered and hopeful; and (7) advocating to improve healthcare for other rare disease patients. Several facilitators (e.g., meeting via teleconference) and barriers (e.g., getting patients and/or family members to lead the group) of establishing and maintaining these

Full Text Available BACKGROUND: Studies using the Supportive Care Needs Survey (SCNS report high levels of unmet supportive care needs (SCNs in psychological and less-so physical & daily living domains, interpreted as reflecting disease/treatment-coping deficits. However, service and culture differences may account for unmet SCNs variability. We explored if service and culture differences better account for observed SCNs patterns. METHODS: Hong Kong (n = 180, Taiwanese (n = 263 and Japanese (n = 109 CRC patients' top 10 ranked SCNS-34 items were contrasted. Mean SCNS-34 domain scores were compared by sample and treatment status, then adjusted for sample composition, disease stage and treatment status using multivariate hierarchical regression. RESULTS: All samples were assessed at comparable time-points. SCNs were most prevalent among Japanese and least among Taiwanese patients. Japanese patients emphasized Psychological (domain mean = 40.73 and Health systems and information (HSI (38.61 SCN domains, whereas Taiwanese and Hong Kong patients emphasized HSI (27.41; 32.92 and Patient care & support (PCS (19.70; 18.38 SCN domains. Mean Psychological domain scores differed: Hong Kong = 9.72, Taiwan = 17.84 and Japan = 40.73 (p<0.03-0.001, Bonferroni. Other SCN domains differed only between Chinese and Japanese samples (all p<0.001. Treatment status differentiated Taiwanese more starkly than Hong Kong patients. After adjustment, sample origin accounted for most variance in SCN domain scores (p<0.001, followed by age (p = 0.01-0.001 and employment status (p = 0.01-0.001. Treatment status and Disease stage, though retained, accounted for least variance. Overall accounted variance remained low. CONCLUSIONS: Health service and/or cultural influences, age and occupation differences, and less so clinical factors, differentially account for significant variation in published studies of SCNs.

The increase in the access to biomedical interventions for people living with HIV/AIDS in the developing world has not been adequately matched with the requisite psychosocial treatments to help improve the effectiveness of biomedical interventions. Therefore, in this study the author seeks to determine whether socio-demographic characteristics and social support are associated with quality of life in individuals diagnosed with HIV/AIDS in Ghana. A convenience sample of 300 HIV/AIDS support group members was obtained via cross-sectional design survey. The Medical Outcome Studies (MOS) HIV Health Survey, the MOS Social Support Survey (MOS-SSS), and demographic questionnaire instruments were used to assess quality of life, social support, and demographic information respectively. Multiple regression analysis showed that there was a positive association between overall social support and overall quality of life (r = .51). It also showed that being younger, male, attending support group meetings for over a year, and having ≥ 13 years of schooling related to higher quality of life. Implications of the findings for practice, policy, and research in Ghana and the rest of the developing world are discussed.

The experimental fast reactor Joyo at Oarai Research and Development Center (ORDC) of Japan Atomic Energy Agency (JAEA) is Japan's sodium-cooled fast reactor (FR). In 2003, this reactor's upgrade to the 140MWt MK-III core was completed to increase the irradiation testing capability. The MK-III core provides the fast neutron flux of 4.0x10 15 n/cm 2 s as an irradiation test bed for improving the fuels and material of FR in Japan. Three post-irradiation examination (PIE) facilities named FMF, MMF and AGF related to Joyo are in ORDC. Irradiated subassemblies and core components are carried into the FMF (Fuel Monitoring Facility) and conducted nondestructive examinations. Each subassembly is disassembled to conduct some destructive examinations and to prepare the fuel and material samples for further detailed examinations. Fuel samples are sent to the AGF (Alpha-Gamma Facility), and material samples are sent to the MMF (Materials Monitoring Facility). These overall and elaborate data provided by PIE contribute to investigate the irradiation effect and behavior of fuels and materials. This facility complex is indispensable to promote the R and D of FR in Japan. And, the function and technology of irradiation test and PIE enable to contribute to the R and D of innovative fission or fusion reactor material which will be required to use under the high neutron exposure.

The contribution under consideration reports on the upcoming challenges of the climate protection financing in developing countries. The extent of the probably required financing and the current status of the development of the developed countries are presented. Ambiguities regarding the out-payment and tracking of the financial contributions for the climate protection are described. Subsequently, a series of general criteria for the evaluation of the different financing sources are invoked. These criteria are based on principles originated from the UNFCC (United Nations Framework Convention on Climate Change; Bonn, Federal Republic of Germany) climate protection negotiations and consider a broader development political context and certain equity considerations. The advantages and disadvantages of potential sources of income of developed countries are discussed in order to fulfil promises for new and additional resources for adaptation measures and preventative measures in developing countries. These arguments are embedded in a general structure and classified with respect to their revenue potential and political feasibility. This analysis is closely based on a methodological approach and on the suggestions made by the AGF. The analysis closes with a brief assessment of the possible effects of the activities of AGF on the Government decision-makers. Furthermore the analysis shows how their results may strengthen the mutual trust of the countries in order to contribute to the climate agreement as well as to the national action.

Full Text Available This paper aims to understand how certain different but interrelated variables such as background, motivation, and social support could lead to an explanation of student attitudes towards math and to an understanding of the defining characteristics of these attitudes in the school environment. Participants consisted of 1719 Portuguese students, from fifth-to-twelfth grade. The study utilizes an adaptation of the “Intrinsic Motivation Inventory” assessing main determinants of intrinsic motivation. One section of the questionnaire—“In my Math Class”—also assesses student perceptions of teacher and peer support as well as student attitudes. The results revealed that, in general, students held positive attitudes towards mathematics and also highlighted the main effects of grade and math achievement on these attitudes. No gender effect was identified although the girls showed a continuous decline in attitudes the further they progressed in school. A hierarchical analysis using structural equation modeling showed that motivation-related variables are the main predictors of attitudes towards mathematics and that teachers and the social support of peers are also highly significant in understanding these attitudes.

One reason of increased psychological and somatic health problems in adolescence is intensification of stress in school and everyday life. There is little evidence to what extent the level of school achievements shapes this relationship. The aim of the study was to investigate determinants of subjective health complaints in schoolaged children, taking into account the interaction effects. Anonymous survey was conducted in Poland in 2013/2014 on the sample of 4,545 students, as a part of the HBSC (Health Behaviour in School-aged Children) study. On the basis of prevalence of eight symptoms in the past 6 months, a standardized index of health complaints (SCL - Subjective Complaints Checklist) was calculated (0-100). To predict its variability three hierarchical linear models (five blocks) were estimated, separately for three levels of school achievements. Support from family, classmates and teachers as well as family communication were considered as protective factors, which can reduce the negative impact of stress. All analyses were adjusted for age, gender and family affluence. The standardized SCL index was equal to 23.2 in boys and 32.5 in girls. The high level of school stress was reported by 28.5% boys and 35.6% girls, respectively. Regarding these two measures, similar patterns of change were observed, increase with age and with deterioration of academic achievement. Final multivariate models explained 22-25% variability of SCL, slightly more among worst students. Accumulation of low family support and high level of school stress caused the highest increase in the SCL index in very good students. School performance is an important determinant of subjective health complaints in adolescence, also modifying the impact of other risk and protective factors.

Full Text Available The article theoretically substantiates the fact that factoring belongs to the main operational activity of a factoring company, and this allowed structuring the factoring business by types of activity. The lack of a unified approach to the classification of factoring (factoring services made it possible to systematize and refine their classification as a basis for developing accounting and analytical support for risk management of factoring business. The authors single out such classification signs as: the right of the reverse claim (reverse, irretrievable, a territorial feature (international, internal, the subject of the factoring contract (real, consensual, the availability of notification of the debtor (conventional, confidential. The structuring of factoring business contributes to the identification of the risks of the economic activities of a factoring company depending on the type of factoring, the development of methodological support for the bookkeeping of factoring transactions in a risk environment, the search for risk management practices and the determination of management effectiveness in general.

Analysis reveals three basic factors which affect the safety of nuclear power reactors: (1) Internal physical properties of the reactor which provide self protection under breakdown and accident conditions; (2) The reliability of technical systems which provide monitoring, control, accident prevention, heat release, and localization of hazardous products during accidents; (3) Reliability of the reactor control personnel. The last of these factors is usually called the human factor. From published data, this factor makes a large contribution to the downtime and accident statistics at nuclear power plants: from 30 to 80% in various countries. Today the importance of the human factor in operating a nuclear power units is rather well recognized. Current ideas on how to increase the reliability of a human operator are reflected in IAEA recommendations and domestic official documents. The concept of 'a culture of safety' is introduced. Basic types of actions to increase the reliability of personnel who control a nuclear reactor are discussed, including: (1) The qualifying and psychological selection and the training of candidates on the operator's obligations. (2) The automation of routine operations which do not require the operator's intellect. (3) Perfecting the work place, information input to the operator, and the organization of the controls

Due to inappropriate agricultural management practices, soil erosion is becoming one of the most dangerous forms of soil degradation in many olive farming areas in the Mediterranean region, leading to significant decrease of soil fertility and yield. In order to prevent further soil degradation, proper measures are necessary to be locally implemented. In this perspective, an increase in the spatial accuracy of remote sensing datasets and advanced image analysis are significant tools necessary and efficient for mapping soil erosion risk on a fine scale. In this study, the Revised Universal Soil Loss Equation (RUSLE) was implemented in the spatial domain using GIS, while a very high resolution satellite image, namely a QuickBird image, was used for deriving cover management (C) and support practice (P) factors, in order to map the risk of soil erosion in Kolymvari, a typical olive farming area in the island of Crete, Greece. The results comprised a risk map of soil erosion when P factor was taken uniform (conventional approach) and a risk map when P factor was quantified site-specifically using object-oriented image analysis. The results showed that the QuickBird image was necessary in order to achieve site-specificity of the P factor and therefore to support fine scale mapping of soil erosion risk in an olive cultivation area, such as the one of Kolymvari in Crete. Increasing the accuracy of the QB image classification will further improve the resulted soil erosion mapping.

Abstract This study aims to investigate the behavior of PSIM’s (Perserikatan Sepakbola Indonesia Mataram supporters. This study used qualitative methods with case study approach. Informants used in this study consist of three members of Brajamusti board and three members of the Maident board. For the triangulation, in this study the Brajamusti President, Chairman of The Maident, and two police officers were interviewed. The results showed that Brajamusti and The Maident are behave fanatic in providing support to PSIM, so that often cause fights between supporters. Factor that cause the broken of Brajamusti is political that made by certain parties for political interests. The positive impact of these two groups of supporters are their contribution for buying tickets in every time they watch PSIM, so it can be a financial support. While the negative impact of the two groups of supporters are the unfair competition between them  that makes support for PSIM become obscured. Keywords: behavior, football, supporters

Consumer-survivors (C/Ss) identify peer support as a resource that facilitates their recovery. However, little is known about the factors that influence or how the peer support relationship (PSR) develops/deteriorates. The purpose of the study was to explore and describe the PSR within the subculture of mental health. Using an ethnonursing method, the study focused on informants from two C/S organizations who received peer support (n = 14). Findings revealed that the PSRs may develop or deteriorate through three, overlapping phases. Contextual factors that influenced the development/deterioration of the PSR are discussed. Understanding the processes and factors that contribute to the development/deterioration of PSRs will enable clinicians and C/Ss to assess and promote the development of healthy, supportive PSRs in mental health.

2014-07-01

This study examines support for the genetic modification (GM) of crops in the context of preventing "late blight," a devastating potato and tomato disease that caused the Irish Potato Famine in the 1850s and results in substantial crop loss today. We surveyed U.S. adults who do the primary grocery shopping in their household (n = 859). Half of the respondents were randomly assigned to read a vignette describing late blight before responding to questions about GM, whereas the other half read a vignette about generic crop disease before responding to questions. We also examine how the perceived fairness of decision makers relates to GM support and the perceived legitimacy of GM decision making. We found that disease specificity mattered less to support and legitimacy than the perceived fairness of decision makers. The perceived risks of GM to human and environmental health negatively related to GM support and legitimacy, whereas the perceived benefits (e.g. reduced threats to crops and a more secure food supply) positively related to support and legitimacy. Objective knowledge about GM had a small, negative relationship with legitimacy whereas self-assessed familiarity with GM had a positive relationship. Overall, the results offer additional confirmation of past findings from more localized settings that perceived fairness of decision makers matters to support for GM and underscore the importance of considering how risk managers' behaviors and actions are perceived alongside individuals' perceptions about the risks and benefits.

McGilton, Katherine S

2010-06-01

To describe the development and psychometric testing of the Supportive Supervisory Scale (SSS). The development of the items of the scale was based on Winnicott's relationship theory and on focus groups with 26 healthcare aides (HCAs) and 30 supervisors from six long-term care (LTC) facilities in Ontario, Canada. Content validity of the 15-item instrument was established by a panel of experts. Based on a secondary analysis of data collected from 222 HCAs in 10 LTC facilities in Ontario, Canada, the SSS was subjected to principal components analysis with oblique rotation. A two-factor solution was accepted, which is consistent with the theoretical conceptualization of the instrument. Factor I was labeled Respects Uniqueness and Factor II was labeled Being Reliable. Internal consistency of Factor I was .95, and that of Factor II was .91. Discriminant validity was also established. The focus groups revealed that "being available to staff" while "recognizing the HCA as an individual, and taking a moment to get to know them" was essential to feeling supported by their supervisor. The SSS is a reliable and valid measure of supervisory support of supervisors working in LTC facilities. At the core of supportive supervision is the supervisor's ability to develop and maintain positive relationships with each HCA. It is through respecting the uniqueness of each HCA and being reliable that supervisor-HCA relationships can flourish. Supportive leadership in LTC settings is a major contributor to HCAs' job satisfaction and retention and to quality of patient care. Therefore, a tool developed and tested to measure supervisors' supportive capacities in LTC is primal to evaluate the effectiveness of supervisors in these environments.

People with physical disability report lower amounts of emotional and informational social support compared with other populations but it is unclear how influences at the broader societal level impact support in this population. To address this question, Berkman and Glass's social-ecological model was used to examine the influence of upstream factors on interpersonal support in people with physical disability. It was predicted that these factors would influence support even after controlling for the traditional measures linked to social support. 331 adult participants with physical disability (43% female; mean age = 42.7; 88% White) completed an online cross-sectional survey measuring types and sources of social support, social integration, disability impact in social domains, environmental barriers, and relevant psychosocial variables such as depression. A hierarchical linear regression analysis showed that level of disability, perceived tangible support, social integration, depressive symptoms, environmental barriers, occupational independence, and having family or friends as primary support sources were significantly associated with perceived support at the final step (R(2) = .60, F(22, 255) = 17.68, p disability than typical measures studied in the literature.

Heparanase is an endo-β-D-glucuronidase dominantly involved in tumor metastasis and angiogenesis. Recently, we demonstrated that heparanase is involved in the regulation of the hemostatic system. Our hypothesis was that heparanase is directly involved in activation of the coagulation cascade. Activated factor X and thrombin were studied using chromogenic assays, immunoblotting and thromboelastography. Heparanase levels were measured by enzyme-linked immunosorbent assay. A potential direct interaction between tissue factor and heparanase was studied by co-immunoprecipitation and far-western assays. Interestingly, addition of heparanase to tissue factor and activated factor VII resulted in a 3- to 4-fold increase in activation of the coagulation cascade as shown by increased activated factor X and thrombin production. Culture medium of human embryonic kidney 293 cells over-expressing heparanase and its derivatives increased activated factor X levels in a non-enzymatic manner. When heparanase was added to pooled normal plasma, a 7- to 8-fold increase in activated factor X level was observed. Subsequently, we searched for clinical data supporting this newly identified role of heparanase. Plasma samples from 35 patients with acute leukemia at presentation and 20 healthy donors were studied for heparanase and activated factor X levels. A strong positive correlation was found between plasma heparanase and activated factor X levels (r=0.735, P=0.001). Unfractionated heparin and an inhibitor of activated factor X abolished the effect of heparanase, while tissue factor pathway inhibitor and tissue factor pathway inhibitor-2 only attenuated the procoagulant effect. Using co-immunoprecipitation and far-western analyses it was shown that heparanase interacts directly with tissue factor. Overall, our results support the notion that heparanase is a potential modulator of blood hemostasis, and suggest a novel mechanism by which heparanase increases the generation of activated

Full Text Available The aims of the current study were to examine the factors affecting implementation of social and emotional aspects of learning (SEAL small group interventions in primary schools and to explore the role of support from Local Authorities (LAs in the implementation process. Telephone interviews were conducted with lead SEAL staff in 12 LAs across England as part of a larger national evaluation of this educational initiative. Data were transcribed and subjected to qualitative content analysis. Subsequently, a tentative model was developed to document the relationship between the nature of support provided by LAs (e.g. training events, developing/providing additional materials, factors affecting implementation at school level (e.g. school readiness, the profile of SEAL and perceived barriers to success (e.g. misconceptions about the purpose of small group interventions. These findings are discussed in relation to the existing literature on the implementation of social-emotional initiatives and interventions in education.

Sørup, Christian Michel; Jacobsen, Peter

2013-01-01

The purpose of this study is to first create an overview of relevant factors directly influencing employee absence in the healthcare sector. The overview is used to further investigate the factors identified using employee satisfaction survey scores exclusively. The result of the overall objective is a management framework that allows managers to gain insight into the current status of risk factors with high influence on employee absence levels. The research consists of a quantitative literature study supported by formal and semi-formal interviews conducted at the case organisations. Employee satisfaction surveys were applied to analyse the development over time of selected factors correlated with concurrent employee absence rates. Checking for causal results, comparisons with the included published literature findings were also carried out. Four major clustered factors, three of which constitute the term "social capital", showed a high degree of connection with employee absence rates. The factors are general satisfaction, fairness, reliance and co-operation. Integrating the four elements in a management framework will provide valuable and holistic information about the determinants with regard to current levels of employee absence. The framework will be a valuable support for leaders with the authority to alter the determinants of employee absence. Since a great part of the empirical material is supplied from the healthcare sector, the results obtained could be restricted to this sector. Inclusion of data from Arbejdsmarkedets Tillaegspension (ATP) showed no deviation from the results in the healthcare sector. The product of the study is a decision support tool for leaders to cope with levels of employee absence. The framework is holistic and can prove to be a valuable tool to take a bearing of where to focus future initiatives. Gathering former observational studies in a complete overview embracing many relevant factors that influence sickness absence has not yet

Nurses are the largest group and an important part of the providers in the health care systems that who a key role in hospitals. Any defect and deficiency in their work can result in irreversible outcomes. This study aimed to determine the effect of supervisors' support and mediating factors on the job performance (JOBPER) of 400 nurses working in the teaching hospitals affiliated to Shiraz University of Medical Sciences, using structural equation modeling. The results showed that the supervisor's support had a significant negative effect on work-family conflict (t = -2.57) and a positive effect on organizational commitment (t = 4.03); Work-family conflict had a significant positive effect on job stress (t = 11.24) and a negative effect on organizational commitment (t = -3.35) and JOBPER (t = -2.29). Family-work conflict had a positive effect on job stress (t = 4.48) and a negative effect on organizational commitment (t = -2.54). Finally, job stress had a negative effect (t = -3.30), and organizational commitment showed a positive effect (t = 5.96) on the studied nurses' JOBPER. According to the results, supervisor's support could influence JOBPER through reducing work-family conflict and increasing organizational commitment. Therefore, to improve the nurses' JOBPER in the hospitals, some strategies are recommended.

Highlights: • With the preliminary hypothesis established, the dynamic displacements are not so high and the state of stress (not reported) does not exhibit large region with plastic strain. • The dynamic displacements show a certain dependency from the mesh adopted, and the geometry chosen. • The energy (kinetic or strain) of the whole structure gives useful information about the key behavior during impact. • In order to better understand the overall phenomenon other details (non-linear material, better evaluation of damping, other disruption rise-times and so on. - Abstract: Among the design activities of the in vessel components for DEMO promoted by European Fusion Development Agreement (EFDA) organization, this work deals with the gap required at the supporting keys of the blanket. Due to its higher operating temperatures compared to the vacuum vessel (VV) ones, this gap will increase during operation. The electro magnetic (EM) loads due to fast disruptions occur on a short time and might accelerate the blanket significantly before it touches the supporting keys, causing an impact of the blanket itself onto the keys. Depending on their stiffness, the EM loads with their short time scale could excite the structure's natural frequencies, causing dynamic amplification. Both phenomena (impact and dynamic amplification) can cause stresses in the structure significantly higher than the static ones. This work develops a finite element model of DEMO blanket to study its non-linear transient dynamic behavior under impact loadings. A VV sector, the ribs between the inner and outer VV, the backward manifolds and the supporting keys of the blanket have been modeled. The analyses have been performed with Abaqus [1] and Ansys [2] FEM codes focused on the displacements of the keys in their housing on the blanket. The dynamic amplification factor has been evaluated as the ratio of dynamic to static displacements in meaningful points of the structure for a growing gap

Describe small business support for youth physical activity opportunities (YPAO) and identify factors associated with this support. Cross-sectional analysis of quantitative data relating business characteristics and support for YPAO. Eight demographically heterogeneous, urban neighborhoods in a Midwest metropolitan area. Adult small business owners (n = 90; 65% response rate; mean age 48.4 years; 73.3% male; 45.2% minority). Neighborhood demographics from the 2000 U.S. Census and self-reported business and owner characteristics. Multivariate analysis of variance was used to contrast business and owner characteristics between businesses that did and did not support YPAO. Businesses supporting YPAO had larger annual operating (F = 7.6; p = .018) and advertising budgets (F = 8.5; p = .009) and had younger owners (F = 6.1; p = .034), with sports backgrounds (χ(2) = 5.6; p = .018) and who felt businesses should support YPAO (χ(2) = 3.8; p = .048). Of the 46 businesses not supporting YPAO, 82.6% felt small businesses should support YPAO. The major reasons for nonsupport were difficulty identifying YPAO to support and not being asked for support. Business (e.g., budgets) and business owner characteristics (e.g., age), owner connectedness with YPAO, and the approach used for garnering support (active solicitation, clearly defined support mechanism) were associated with supporting YPAO. Additional business (e.g., annual revenues), owner (e.g., perceptions of YPAO), and environmental (e.g., crime rate, land use) factors should be examined as potential correlates.

Iron oxide (α-Fe2O3) nanocrystals have been synthesized via the sol-gel technique. The structural and morphological features of these nanocrystals were studied using x-ray diffraction, Fourier transform-infrared spectroscopy and transmission electron microscopy. Colloidal solution of synthesized α-Fe2O3 (hematite) was spin-coated onto a single-crystal p-type silicon (p-Si) wafer to fabricate a heterojunction diode with Mansourconfiguration Ag/Fe2O3/p-Si/Al. This diode was electrically characterized at room temperature using current-voltage (I-V) characteristics in the voltage range from -9 V to +9 V. The fabricated diode showed a good rectification behavior with a rectification factor 1.115 × 102 at 6 V. The junction parameters such as ideality factor, barrier height, series resistance and shunt resistance are determined using conventional I-V characteristics. For low forward voltage, the conduction mechanism is dominated by the defect-assisted tunneling process with conventional electron-hole recombination. However, at higher voltage, I-V ohmic and space charge-limited current conduction was became less effective with the contribution of the trapped-charge-limited current at the highest voltage range.

Psychological Support as a Factor of the Training Process Quality Improvement

2017-06-01

Full Text Available Supportive activities may be one of the ways of the training process optimization. Support involves both components of the training process, i.e. training and rest. The training support is aimed at the training load increase or at such orientation of the adaptation processes to meet the training goals as closely as possible. The different aims lay behind the methods that support the rest mechanisms. It is about increasing the peace of the regeneration and recovery processes. This term describes all activities aimed at restoring the full exercise capacity of the athlete after work. The psychological support of the training process can be one of the ways to minimize training disturbances and it should therefore be an essential part of the training process management in case of the top ranked athletes. To improve the psychological support system of the training process and to improve the system quality, it is necessary to analyze the current situation. That’s why, authors of the paper decided to ask the members of the Polish Olympic team competed at the 2016 Olympic Games in Rio de Janeiro on types of relaxation techniques they accepted and used before the competition. The relaxation techniques were deliberately limited to the pre-start relaxation techniques as the study was treated as a pilot study dedicated to the problem identification. Therefore, the authors of the paper formulated its aim, as the identification of the pre-start relaxation preferences of the Olympic team members. The following research questions were formulated to meet the aim of the study:  •     What types of the pre-start relaxation techniques are declared and accepted by the Olympians? •     Could the preferred pre-start relaxation techniques be considered rational, planned, and consciously implemented? A written interview with an online questionnaire was used as a research method. The study was conducted before the 2016 Olympic Games in Rio de

Identify what factors are associated with functional social support and social network post stroke; explore stroke survivors' perspectives on what changes occur and how they are perceived. The following electronic databases were systematically searched up to May 2015: Academic Search Complete; CINAHL Plus; E-journals; Health Policy Reference Centre; MEDLINE; PsycARTICLES; PsycINFO; and SocINDEX. PRISMA guidelines were followed in the conduct and reporting of this review. All included studies were critically appraised using the Critical Appraisal Skills Program tools. Meta-ethnographic techniques were used to integrate findings from the qualitative studies. Given the heterogeneous nature of the quantitative studies, data synthesis was narrative. Seventy research reports met the eligibility criteria: 22 qualitative and 48 quantitative reporting on 4,816 stroke survivors. The qualitative studies described a contraction of the social network, with non-kin contact being vulnerable. Although family were more robust network members, significant strain was observed within the family unit. In the quantitative studies, poor functional social support was associated with depression (13/14 studies), reduced quality of life (6/6 studies) and worse physical recovery (2/2 studies). Reduced social network was associated with depression (7/8 studies), severity of disability (2/2 studies) and aphasia (2/2 studies). Although most indicators of social network reduced post stroke (for example, contact with friends, 5/5 studies), the perception of feeling supported remained relatively stable (4/4 studies). Following a stroke non-kin contact is vulnerable, strain is observed within the family unit, and poor social support is associated with depressive symptoms. © The Author(s) 2015.

Field evaluation of support practice (P-factor) for stone walls to control soil erosion in an arid area (Northern Jordan)

Gharaibeh, Mamoun; Albalasmeh, Ammar

2017-04-01

Stone walls have been adopted for long time to control water erosion in many Mediterranean countries. In soil erosion equations, the support practice factor (P-factor) for stone walls has not been fully studied or rarely taken into account especially in semi-arid and arid regions. Field studies were conducted to evaluate the efficiency of traditional stone walls and to quantify soil erosion in six sites in north and northeastern Jordan. Initial estimates using the Universal Soil Loss Equation (USLE) showed that rainfall erosion was reduced by 65% in areas where stone walls are present. Annual soil loss ranged from 5 to 15 t yr-1. The mean annual soil loss in the absence of stone walls ranged from 10-60 t ha-1 with an average value of 35 t ha-1. Interpolating the slope of thickness of A horizon provided an average initial estimate of 0.3 for P value.

A human factors project on the use of nuclear by-product material to treat cancer using remotely operated afterloaders was undertaken by the Nuclear Regulatory Commission. The purpose of the project was to identify factors that contribute to human error in the system for remote afterloading brachytherapy (RAB). This report documents the findings from the second, third, fourth, and fifth phases of the project, which involved detailed analyses of four major aspects of the RAB system linked to human error: human-system interfaces; procedures and practices; training practices and policies; and organizational practices and policies, respectively. Findings based on these analyses provided factual and conceptual support for the final phase of this project, which identified factors leading to human error in RAB. The impact of those factors on RAB performance was then evaluated and prioritized in terms of safety significance, and alternative approaches for resolving safety significant problems were identified and evaluated

Lack of social support and high levels of stress represent potentially modifiable risk factors for cognitive aging. In this study we examined the relationships between these two risk factors and response time inconsistency (RTI), or trial-to-trial variability in choice response time tasks. RTI is an early indicator of declining cognitive health, and examining the influence of modifiable psychosocial risk factors on RTI is important for understanding and promoting cognitive health during adulthood and old age. Using data from a community sample study (n = 317; M age = 49, range = 19-83), we examined the effects of social support, including size of network and satisfaction with support, global perceived stress, and their interactions on RTI. Neither size of network nor satisfaction with support was associated with RTI independent of perceived stress. Stress was positively associated with increased RTI on all tasks, independent of social support. Perceived stress did not interact with either dimension of social support to predict RTI, and perceived stress effects were invariant across age and sex. Perceived stress, but not social support, may be a unique and modifiable risk factor for normal and pathological cognitive aging. Discussion focuses on the importance of perceived stress and its impact on RTI in supporting cognitive health in adulthood and old age.

Fuji Electric Co., Ltd., in collaboration with Shitashion Japan and Arthur Andersen Ltd., developed a 'marketing analysis support system' which integrally analyzes evaluation factors of various dimensions explaining consumers' purchasing behaviors and which supports business for the efficient operation of product development and demand prediction. This system breaks down products into each evaluation factor from psychological and physical viewpoints, and carries out various kinds of multivariate analysis, thereby making it easy to understand visually, for example, what evaluation factors decide relative positional relations between evaluation factors or between products as well as the position of a product in the whole. Further, more precise marketing analysis and prediction become possible by visually grasping blank areas of products, extent of competition, distribution of products, composition of product series, etc. (translated by NEDO)

2015-05-01

Full Text Available Purpose: The exactly and precisely supply of carrying spare parts has a crucial impact on support and could improve the performance of equipment. Spare parts support is the crux work which will be limited by spare parts allocation and support cost input. Reasonable support strategy can help in making good use of available resources and support the equipment in normal operational status. The purpose of this paper is to propose a dynamics model of spare parts support process based on considering the interaction of multiple factors, and explores the regulation of dynamics behavior in the system. In order to achieve the optimization strategy to improve the effect of support so that will enhance the relevant support parameters of equipment. Design/methodology/approach: Meditate the feedback relationship among some important factors of support that involve support cost, support time and maintenance ability. System dynamics theory is adopted to propose a dynamics model of spare parts support process, on the analysis of multiple factors and casual relationship to find some major ones which have crucial impact on spare parts support. Spare parts support cost and availability was regarded as the control objective, moreover, adjust the control paramours and improve the effect of cannibalization and lateral supply scheduling strategy for spares support. Findings: The factors of spare parts supply, demand and maintenance have relationship of control feedback, and adjust the value of some crucial factors can reduce the support cost and improve the availability value. The main finding is that adopting cannibalization strategy under condition of available materials can relieve the mission and operational availability decline caused by shortage of spare parts. Combining the lateral supply and cannibalization strategy can reduce the inventory of warship carrying spare parts. Practical implications: By controlling the value of key factors regarding aspect of spare

Apigenin and anthocyanin biosyntheses share common precursors in plants. Flavone synthase (FNS) converts naringenin into apigenin in higher plants. Celery is an important edible and medical vegetable crop that contains apigenin in its tissues. However, the effect of high AgFNS gene expression on the apigenin and anthocyanins contents of purple celery remains to be elucidated. In this study, the AgFNS gene was cloned from purple celery ('Nanxuan liuhe purple celery') and overexpressed in this purple celery to determine its influence on anthocyanins and apigenin contents. Results showed that the AgFNS gene was 1068bp, which encodes 355 amino acid residues. Evolution analysis showed that the AgFNS protein belongs to the FSN I type. In AgFNS transgenic celery, the anthocyanins content in petioles was lower than that wild-type celery plants. Apigenin content increased in the petioles of AgFNS transgenic celery. The transcript levels of the AgPAL, AgC4H, AgCHS, and AgCHI genes were up-regulated, whereas those of the AgF3H, AgF3'H, AgDFR, AgANS, and Ag3GT genes were down-regulated in the petioles of AgFNS transgenic plants compared with wild-type celery plants. This work provides basic knowledge about the function of the AgFNS gene in the anthocyanin and apigenin biosyntheses of celery. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available In contrast to previous studies which employed zero-valent iron powder, this paper investigated reductive dechlorination of hexachloroethane (HCA using iron shavings and bimetallic iron shavings modified with Cu, Ag, or Pd. Results clearly show that iron shavings offer superior reductive dechlorination of HCA. In addition, surface-normalized pseudo first-order dechlorination rates of 0.0073 L·m−2·h−1, 0.0136 L·m−2·h−1, 0.0189 L·m−2·h−1, and 0.0084 L·m−2·h−1 were observed in the presence of iron shavings (Fe0 and the bimetallic iron shavings Cu/Fe, Ag/Fe, and Pd/Fe, respectively. Bimetallic iron shavings consisting of Cu/Fe and Ag/Fe could greatly enhance the reductive reaction rate; Pd/Fe was used to achieve complete dechlorination of HCA within 5 hours. The additives of Ag and Pd shifted product distributions, and the reductive dechlorination of HCA occurred via β reductive elimination and sequential hydrogenolysis in the presence of all iron shavings. This study consequently designed a reaction pathway diagram which reflected the reaction pathway and most prevalent dechlorination products. Iron shavings are a common byproduct of mechanical processing plants. While the purity of such Fe metals may be low, these shavings are readily available at low costs and could potentially be used in engineering applications such as contamination control technologies.

Rationale Low social support has been linked to negative health outcomes in breast cancer patients. Objective We examined associations between perceived social support, neighborhood socioeconomic deprivation, and neighborhood-level social support in early-stage breast cancer patients and controls. Methods This two-year longitudinal study in the United States included information collected from telephone interviews and clinical records of 541 early-stage patients and 542 controls recruited from 2003 to 2007. Social support was assessed using the Medical Outcomes Study Social Support Survey (MOS-SS). Residential addresses were geocoded and used to develop measures including neighborhood social support (based on MOS-SS scores from nearby controls) and neighborhood socioeconomic deprivation (a composite index of census tract characteristics). Latent trajectory models were used to determine effects of neighborhood conditions on the stable (intercept) and changing (slope) aspects of social support. Results In a model with only neighborhood variables, greater socioeconomic deprivation was associated with patients’ lower stable social support (standardized estimate = −0.12, p = .027); neighborhood-level social support was associated with social support change (standardized estimate = 0.17, p = .046). After adding individual-level covariates, there were no direct neighborhood effects on social support. In patients, neighborhood socioeconomic deprivation was associated with support indirectly through marriage, insurance status, negative affect, and general health. In controls, neighborhood socioeconomic deprivation was associated with support indirectly through marriage (p social support differed in patients and controls. Psychosocial and neighborhood interventions may help patients with low social support, particularly patients without partnered relationships in deprived areas. PMID:27017091

2014-06-01

Full Text Available Abstract—Knowledge management is supported by many strategies such as business intelligence, collaboration, document management and e-learning. With the development of modern information technology and the increases of demand for building and maintaining dynamic capabilities, E-learning has played more and more important role of all the technologies in the supporting knowledge management. A successful e-learning system is supported by many critical success factors and technology has become the key factor among these factors. Consequently, the review of basic technologies and corresponding products that support e-learning will be in favor of further study on e-learning. From perspective of knowledge management, this paper makes a review about the relationship between e-learning and knowledge management and advanced technologies and corresponding products that support the design and operation of e-learning system. At the end of this paper, we analyze the main trends of the development direction of e-learning technology.

Seismic structural response analysis for multiple support excitation

International Nuclear Information System (INIS)

Shaw, D.E.

1975-01-01

In the seismic analysis of nuclear power plant equipment such as piping systems situations often arise in which piping systems span between adjacent structures or between different elevations in the same structure. Owing to the differences in the seismic time history response of different structures or different elevations of the same structure, the input support motion will differ for different supports. The concept of a frequency dependent participation factor and rotational response spectra accounting for phase differences between support excitations is developed by using classical equations of motion to formulate the seismic response of a structure subjected to multiple support excitation. The essence of the method lies in describing the seismic excitation of a multiply excited structure in terms of translational and rotational spectra used at every support and a frequency dependent spatial distribution function derived from the phase relationships of the different support time histories. In this manner it is shown that frequency dependent participation factors can be derived from the frequency dependent distribution functions. Examples are shown and discussed relative to closed form solutions and the state-of-the-art techniques presently being used for the solution of problems of multiply excited structures

This study used respondent-driven sampling to explore the effects of social support on HIV risk and protective factors among young males who have sex with males (YMSM) in Bangkok (N = 273) and Chiang Mai (N = 243), Thailand. It compared different measures of social support, including living situation, the proportion of family and friends to whom the respondent had disclosed their same-sex attraction, and scores on the multi-dimensional scale of perceived social support as predictors of two outcomes of interest-coerced first sex and HIV knowledge. Social support from family played a mediating role in both outcomes among YMSM in Bangkok but not those from Chiang Mai. Though social support from friends was also studied, it was less strongly associated with the outcomes of interest. The findings support interventions designed to leverage social support networks to increase HIV knowledge and decrease coerced first sex among YMSM. At the same time, they demonstrate that there is not a single risk or demographic profile encompassing all YMSM. Successful programs and policies will need to consider the specific attributes and social environment of YMSM in particular locations in order to effectively address HIV risks.

Chavis, Llena

2016-07-01

This study investigated anxiety as a phenomenon distinct from depression and evaluated several variables that influence anxiety in first-time mothers. This explored the relationship between maternal sense of competence (both of mothering and efficacy) and perceived social support (from family, friends, and significant others) and first-time mothers' postpartum anxiety, when depression, socioeconomic status (SES), and marital status were controlled for. The population studied were 86 first-time mothers made up of women with children 24 months or younger in two populations of Kentucky and Michigan. The constructs of maternal sense of competence and perceived social support were found to be significant in explaining first-time mothers' anxiety. The study concluded that a combined association of perceived social support and maternal sense of competence were associated with a 34% (change in R-squared = .339) decrease of a first-time mothers' anxiety. However, not all types of social support, or maternal competence appeared to be equally important with regards to maternal anxiety: social support from friends and family and maternal sense of competence in regard to productivity appeared to be most significant. Lastly, some recommendations for health practitioners who work with mothers are provided.

The authors examined trends and predictors of public support for smoke-free restaurants in Massachusetts. Since 1992, the Massachusetts Behavioral Risk Factor Surveillance System has asked survey respondents about their attitudes toward smoking in restaurants. Analyses using data from 1992 to 1999 characterized changes over time in support for smoke-free restaurants and the role of demographic and smoking-related factors in predicting support. During 1992 to 1999, the rate of support for smoke-free restaurants increased from 37.5% to 59.8%, with similar increases among current, former, and never smokers. After adjustment for smoking status, support was associated with socioeconomic characteristics, race/ethnicity, and household smoking rules. Among current smokers, lighter smokers and those who were trying to quit were more likely to endorse smoke-free restaurants. There has been a substantial increase in support for smoke-free restaurants among both smokers and nonsmokers in Massachusetts.

Full Text Available As important as it is to fully comprehend the relationship between stress and depression among university students, it is also vital to ascertain the role of perceived social support as an essential psychosocial factor for effectively delimiting the deleterious impact of stress exposure. As such, the current study aimed to examine whether perceived social support functioned as a mediating factor in the relationship between stress and depression among university students. Data was collected from undergraduate students of a public university in Sarawak, Malaysia. Information on demographics, depression, stress and perceived social support were collated through self-report questionnaires. Results revealed significant gender differences for perceived social support, wherein female students reported lower levels of social support compared to their counterparts. Mediation analysis portrayed that the association between stress and depression was partially accounted for, by the mediating role of perceived social support.

Individual Placement and Support is a vocational rehabilitation programme for people with severe mental illness, which was implemented during the period 2003-2005 at four locations in the Netherlands. To investigate the degree of compliance with the Individual Placement and Support programme, the factors that hindered or facilitated its implementation, and the results. The degree of compliance was assessed using the Individual Placement and Support fidelity scale. Data regarding the factors that hindered or facilitated the implementation were collected via interviews and monitoring. In addition, data were collected on patient characteristics, the support provided and the jobs found. None of the locations achieved the highest level of compliance, although two locations came close. Eighteen per cent of the 316 patients were helped to find a regular job. The most important obstacles to implementation were loss of vocational team members, project leaders' lack of time, lack of finance, and insufficient cooperation between the organisations involved. The most important facilitating factors were the skills and commitment of the vocational team member(s) and the integration of the vocational teammember(s) and the mental health team. It is not easy to implement Individual Placement and Support. However, if more attention is given to good project management, Individual Placement and Support can succeed in the Netherlands.

This study examines the relationships between personality, on the one hand, and perceived availability of social support (PASS) and satisfaction with received social support (SRSS), on the other hand, in women with early stage breast cancer (BC). In addition, this study examined whether a stressful event (i.e., diagnosis) is associated with quality of life (QOL), when controlling for PASS and SRSS. Women were assessed on PASS and SRSS (World Health Organization QOL assessment instrument-100) before diagnosis (time 1) and 1 (time 2), 3 (time 3), 6 (time 4), 12 (time 5), and 24 months (time 6) after surgical treatment. Personality (neuroticism extraversion openness five-factor inventory and state trait anxiety inventory-trait scale) and fatigue (fatigue assessment scale) were assessed at time 1. Agreeableness and fatigue predicted PASS and SRSS at time 5 and time 6. Trait anxiety had a negative effect on SRSS (ss = -0.22, p personality factors substantially influence the way women with early stage BC perceive social support. Knowledge about these underlying mechanisms of social support is useful for the development of tailor-made interventions. Professionals should be aware of the importance of social support. They should check whether patients have sufficient significant others in their social environment and be sensitive to potential discrepancies patients might experience between availability and adequacy of social support.

The study examined a new child report measure of maternal support following child sexual abuse. One hundred and forty-six mother-child dyads presenting for a forensic evaluation completed assessments including standardized measures of adjustment. Child participants also responded to 32 items considered for inclusion in a new measure, the Maternal Support Questionnaire-Child Report (MSQ-CR). Exploratory factor analysis of the Maternal Support Questionnaire-Child Report resulted in a three factor, 20-item solution: Emotional Support (9 items), Skeptical Preoccupation (5 items), and Protection/Retaliation (6 items). Each factor demonstrated adequate internal consistency. Construct and concurrent validity of the new measure were supported in comparison to other trauma-specific measures. The Maternal Support Questionnaire-Child Report demonstrated sound psychometric properties. Future research is needed to determine whether the Maternal Support Questionnaire-Child Report provides a more sensitive approximation of maternal support following disclosure of sexual abuse, relative to measures of global parent-child relations and to contextualize discrepancies between mother and child ratings of maternal support.

Social support is associated with well-being and positive health outcomes. However, positive outcomes of social support might be more dependent on the way support is provided than the amount of support received. A distinction can be made between directive social support, where the provider resumes responsibility, and nondirective social support, where the receiver has the control. This study examined the relationship between directive and nondirective social support, and subjective health complaints, job satisfaction and perception of job demands and job control. A survey was conducted among 957 Norwegian employees, working in 114 private kindergartens (mean age 40.7 years, SD = 10.5, 92.8% female), as part of a randomized controlled trial. This study used only baseline data. A factor analysis of the Norwegian version of the Social Support Inventory was conducted, identifying two factors: nondirective and directive social support. Hierarchical regression analyses were then performed. Nondirective social support was related to fewer musculoskeletal and pseudoneurological complaints, higher job satisfaction, and the perception of lower job demands and higher job control. Directive social support had the opposite relationship, but was not statistically significant for pseudoneurological complaints. It appears that for social support to be positively related with job characteristics and subjective health complaints, it has to be nondirective. Directive social support was not only without any association, but had a significant negative relationship with several of the variables. Nondirective social support may be an important factor to consider when aiming to improve the psychosocial work environment. Clinicaltrials.gov: NCT02396797. Registered 23 March 2015.

Full Text Available Background The main purpose of this study was to identify factors that influence healthcare quality in the Iranian context. Methods Exploratory in-depth individual and focus group interviews were conducted with 222 healthcare stakeholders including healthcare providers, managers, policy-makers, and payers to identify factors affecting the quality of healthcare services provided in Iranian healthcare organisations. Results Quality in healthcare is a production of cooperation between the patient and the healthcare provider in a supportive environment. Personal factors of the provider and the patient, and factors pertaining to the healthcare organisation, healthcare system, and the broader environment affect healthcare service quality. Healthcare quality can be improved by supportive visionary leadership, proper planning, education and training, availability of resources, effective management of resources, employees and processes, and collaboration and cooperation among providers. Conclusion This article contributes to healthcare theory and practice by developing a conceptual framework that provides policy-makers and managers a practical understanding of factors that affect healthcare service quality.

Full Text Available BACKGROUND: The aim of this study is to present an objective method based on support vector machines (SVMs and gravitational search algorithm (GSA which is initially utilized for recognition the pattern among risk factors and hypertension (HTN to stratify and analysis HTN’s risk factors in an Iranian urban population. METHODS: This community-based and cross-sectional research has been designed based on the probabilistic sample of residents of Isfahan, Iran, aged 19 years or over from 2001 to 2007. One of the household members was randomly selected from different age groups. Selected individuals were invited to a predefined health center to be educated on how to collect 24-hour urine sample as well as learning about topographic parameters and blood pressure measurement. The data from both the estimated and measured blood pressure [for both systolic blood pressure (SBP and diastolic blood pressure (DBP] demonstrated that optimized SVMs have a highest estimation potential. RESULTS: This result was particularly more evident when SVMs performance is evaluated with regression and generalized linear modeling (GLM as common methods. Blood pressure risk factors impact analysis shows that age has the highest impact level on SBP while it falls second on the impact level ranking on DBP. The results also showed that body mass index (BMI falls first on the impact level ranking on DBP while have a lower impact on SBP. CONCLUSION: Our analysis suggests that salt intake could efficiently influence both DBP and SBP with greater impact level on SBP. Therefore, controlling salt intake may lead to not only control of HTN but also its prevention.

Objective This paper describes the development of the Leading by Example (LBE) instrument. Methods Exploratory factor analysis was used to obtain an initial factor structure. Factor validity was evaluated using confirmatory factor analysis methods. Cronbach’s alpha and item-total correlations provided information on the reliability of the factor subscales. Results Four subscales were identified: business alignment with health promotion objectives; awareness of the health-productivity link; worksite support for health promotion; leadership support for health promotion. Factor by group comparisons revealed that the initial factor structure is effective in detecting differences in organizational support for health promotion across different employee groups Conclusions Management support for health promotion can be assessed using the LBE, a brief, self-report questionnaire. Researchers can use the LBE to diagnose, track, and evaluate worksite health promotion programs. PMID:18517097

To determine the relationship between social support and mortality in older adults, independent of other health conditions. This was a longitudinal study using the database of the 2006 SABE Study (Heath, Well-being and Aging), composed of 1413 individuals aged 60 years and over, living in São Paulo/Brazil. The present study used a questionnaire constructed for the SABE Study, which was reviewed by experts of Latin America and the Caribbean. The social network was evaluated using the variables: social support received; social support offered; number of members in the social network. The covariates included were age, gender, living arrangements, marital status, income, education, comorbidity, depressive symptoms, cognition and functional difficulties. Death as an outcome was evaluated after four years of follow-up. From a total of 1413 older adults at baseline, 268 died in a mean follow-up period of 3,9 years (SE=0,03). In the model adjusted offering social support and having networks composed of 9 or more members reduced the risk of death in the older adults. This study suggest that older adult who are offered support can benefit from mutual exchanges since reciprocity in relationships improves psychological well-being and is indicative of the quality of relationships. Thus, the older adults are part of a group of people whose role is not only to receive, but also to provide help to others, and the support offered seems to be as important as that received.

Full Text Available Background Women with HIV/AIDS (WLWHA have a complex psychosocial burden and a tendency to negative self-esteem, possibly resulting in mental and emotional problems. They need family support to deal with the HIV/AIDS infection and its psychosocial burden. The purpose of this study was to determine chacteristics of family support, self-esteem, and depression of WLWHA and the relationship between family support and self-esteem and depression. Method This was a cross-sectional study of 99 WLWHA infected through their husbands/partners, with no history of drug abuse. The data was taken by a consecutive sampling of two proportions test at Dharmais Cancer Hospital from November 2013 – January 2014. The instruments comprised a demographic questionnaire, the Rosenberg Self-Esteem questionnaire, the Hamilton Depression Rating Scale (HDRS, and a family support questionnaire. The data was analyzed by binary logistic regression. Results There were 99 respondents with mean age of 36 years, of whom 44.4% were high school graduates, 54.5% unemployed, and 91.9% had HIV/AIDS for more than a year. Binary logistic regression analysis showed no significant relationship between family support and self-esteem (p=0.700 and depression (p=0.396. Good family support has a protective effect of 1.3 times (OR=0.772; 95%CI: 0.138-3.770 towards increasing self-esteem, whereas poor family support increases the risk of depression 1.5 times (OR=1.477; 95%CI: 0.598-3.645 in WLWHA infected with HIV/AIDS from their husband/partner. Conclusions Good family support tend to have a protective effect towards increasing self-esteem, whereas poor family support increases the risk of depression in WLWHA infected with HIV/AIDS from their husband/partner.

Most staff working in intellectual disability services will be confronted with people with intellectual disabilities who need support around death, dying and bereavement. Previous studies suggest that intellectual disability staff tend to protect clients from knowing about death and avoid communication about death. The aims of this study were to gain further insight into the individual, organisational and contextual factors that affect the communication of death-related bad news to people with intellectual disabilities by intellectual disability staff and to develop guidelines for services to enable appropriate communication with clients about death and dying. Semi-structured interviews were held with 20 social care staff working in intellectual disability residential or supported living services in London, who had supported a client affected by death-related bad news in the past 6 months. Staff found supporting people with intellectual disabilities around death and dying extremely difficult and tended to avoid communication about death. The following factors had a particularly strong influence on staff practice around communicating death-related bad news: fear and distress around death; life and work experience; and organisational culture. Staff attitudes to death communication had a stronger influence than their client's level of cognitive or communicative abilities. Managers were important role models. Service managers should ensure not only that all their staff receive training in death, loss and communication but also that staff are enabled to reflect on their practice, through emotional support, supervision and team discussions. Future work should focus on the development and testing of strategies to enable intellectual disability staff to support their clients in the areas of dying, death and bereavement. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

To establish variables which are associated with favourable Advanced Life Support (ALS) course assessment outcomes, maximising learning effect. Between 1 January 2013 and 30 June 2014, 8218 individuals participated in a Resuscitation Council (UK) e-learning Advanced Life Support (e-ALS) course. Participants completed 5-8h of online e-learning prior to attending a one day face-to-face course. e-Learning access data were collected through the Learning Management System (LMS). All participants were assessed by a multiple choice questionnaire (MCQ) before and after the face-to-face aspect alongside a practical cardiac arrest simulation (CAS-Test). Participant demographics and assessment outcomes were analysed. The mean post e-learning MCQ score was 83.7 (SD 7.3) and the mean post-course MCQ score was 87.7 (SD 7.9). The first attempt CAS-Test pass rate was 84.6% and overall pass rate 96.6%. Participants with previous ALS experience, ILS experience, or who were a core member of the resuscitation team performed better in the post-course MCQ, CAS-Test and overall assessment. Median time spent on the e-learning was 5.2h (IQR 3.7-7.1). There was a large range in the degree of access to e-learning content. Increased time spent accessing e-learning had no effect on the overall result (OR 0.98, P=0.367) on simulated learning outcome. Clinical experience through membership of cardiac arrest teams and previous ILS or ALS training were independent predictors of performance on the ALS course whilst time spent accessing e-learning materials did not affect course outcomes. This supports the blended approach to e-ALS which allows participants to tailor their e-learning experience to their specific needs. Copyright © 2017 Elsevier B.V. All rights reserved.

Environmental sources of psychosocial support have been found to modulate or protect against the development of psychopathology and risk behavior among adolescents. Capturing sources of environmental support across multiple developmental contexts requires the availability of well-validated, concise assessments-of which there are few in the existing literature. In order to address this need, the current study explored the factor structure, concurrent and convergent validity of the Environmental Supports Scale (ESS; Genetic, Social, and General Psychology Monographs, 117; 395-417, 1991) with a community sample of adolescents. An unconstrained exploratory factor analysis revealed a separate factor for home, school, and neighborhood settings. Internal consistency and test-retest reliability were evaluated for each factor. Concurrent and predictive validity analyses revealed that the ESS was associated in the expected directions across a range of constructs relevant to adolescent development including internalizing symptoms, well-being, external influences, and engagement in risk behavior. Convergent validity for the neighborhood context was established with an assessment of neighborhood environmental adversity. A brief assessment of perceived environmental support across key developmental contexts provides an important tool for research on resilience processes during adolescence and may help illuminate key protective factors and inform intervention and prevention efforts.

Chen, S. Y.; Liu, J. Z.; Guo, F. L.

2017-12-01

This paper presents an analytical study on evaluation of support loss in micromechanical resonators undergoing in-plane flexural vibrations. Two-dimensional elastic wave theory is used to determine the energy transmission from the vibrating resonator to the support. Fourier transform and Green's function technique are adopted to solve the problem of wave motions on the surface of the support excited by the forces transmitted by the resonator onto the support. Analytical expressions of support loss in terms of quality factor, taking into account distributed normal stress and shear stress in the attachment region, and coupling between the normal stress and shear stress as well as material disparity between the support and the resonator, have been derived. Effects of geometry of micro-beam resonators, and material dissimilarity between support and resonator on support loss are examined. Numerical results show that 'harder resonator' and 'softer support' combination leads to larger support loss. In addition, the Perfectly Matched Layer (PML) numerical simulation technique is employed for validation of the proposed analytical model. Comparing with results of quality factor obtained by PML technique, we find that the present model agrees well with the results of PML technique and the pure-shear model overestimates support loss noticeably, especially for resonators with small aspect ratio and large material dissimilarity between the support and resonator.

Supporting member design for equipment and pipes is the requisite factor to realize the concept. It's a challenge to design a reliable supporting structure in molten salt reactor (MSR) due to the extraordinary working temperature (max 750 deg. C). High temperature may cause large expansion and reduce the mechanical strength of material, The support is required both enough strength and flexibility. In this paper, an all-dimensional support was designed, the validation work was carried out on a high temperature test loop. The results indicate that the support has a good performance, it reduce the thermal stress effectively and support the equipment and pipes stably for one year. The support design has a significance referential meaning for MSR construction (authors)

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.

There are all kind of support programs to support entrepreneurship. There are several ways of supporting entrepreneurship, where the person, the entrepreneur, is seen as one of the key factors for stimulating entrepreneurship. The support of the person is what I mention as soft support. To avoid confusion and to get insight in the different kinds of soft support of the entrepreneur, different terms used for this support should be put into perspective. Soft support like coaching, mentoring, co...

Participation in sports has been shown to be protective against depression and suicidal ideation, but little is known about what factors mediate these relationships. No previous studies examined potential mediators between sports participation and suicidal ideation and only one study explored possible mediators between sports participation and depression. Increased sports participation could protect against depression and suicidal ideation by increasing endogenous endorphin levels, boosting self-esteem, improving body image, increasing social support, and affecting substance abuse. Multivariate hierarchical logistic regression analyses of Add Health data to explore whether increased participation in sports (none, 1-2, 3-4, or 5 or more times per week) is associated with depression and suicidal ideation and whether exercise, self-esteem, body weight, social support, and substance abuse mediate these relationships. As sports participation increases, the odds of suffering from depression decreases by 25% (OR: 0.75; 95% CI: 0.70-0.82) and the odds of having suicidal ideation decreases by 12% (OR: 0.88; 95% CI: 0.83-0.93) after controlling for sex, age, race/ethnicity, public assistance, and physical limitations. Substance abuse, body weight, and exercise did not mediate these associations. Consistent with self-esteem and social support acting as mediators of these relationships, the inclusion of these variables in the multivariate models attenuated the associations for depression (OR: 0.83; 95% CI: 0.75-0.91) and suicidal ideation (OR: 0.93; 95% CI: 0.88-0.99). Adolescents should be offered ample opportunity and encouragement to participate in sports, which can protect against depression and suicidal ideation by boosting self-esteem and increasing social support.

The relationship between social support and work-family conflict is well-established, but the notion that different forms, sources, and types of social support as well as contextual factors can alter this relationship has been relatively neglected. To address this limitation, the current study provides the most comprehensive and in-depth examination of the relationship between social support and work-family conflict to date. We conduct a meta-analysis based on 1021 effect sizes and 46 countries to dissect the social support and work-family conflict relationship. Using social support theory as a theoretical framework, we challenge the assumption that social support measures are interchangeable by comparing work/family support relationships with work-family conflict across different support forms (behavior, perceptions), sources (e.g., supervisor, coworker, spouse), types (instrumental, emotional), and national contexts (cultural values, economic factors). National context hypotheses use a strong inferences paradigm in which utility and value congruence theoretical perspectives are pitted against one another. Significant results concerning support source are in line with social support theory, indicating that broad sources of support are more strongly related to work-family conflict than are specific sources of support. In line with utility perspective from social support theory, culture and economic national context significantly moderate some of the relationships between work/family support and work interference with family, indicating that social support is most beneficial in contexts in which it is needed or perceived as useful. The results suggest that organizational support may be the most important source of support overall. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Institutional Support for the Virtual Professor

Full Text Available Academics who hold positions at single-mode, distance education institutions are presently being hampered by an adherence to a long-standing set of protocols (specific office location, face-to-face meetings that were put in place when the conventional post-secondary was the norm. With the advent of a powerful merging of personal computers and the internet, a shift from those protocols to one of support for the virtual professor is in the offing, to the benefit of both the professoriate and the student. A key factor in this shift is the degree and quality of institutional support that will allow these changes to take place. This paper focuses on a number of the key factors that will have to be addressed if this new type of distance education academic is to function effectively.

Full Text Available Abstract Background Veno-arterial extracorporeal membrane oxygenation (ECMO is a common modality of circulatory assist device used in children. We assessed the outcome of children who had ECMO following repair of congenital cardiac defects (CCD and identified the risk factors associated with hospital mortality. Methods From April 1990 to December 2003, 53 patients required ECMO following surgical correction of CCD. Retrospectively collected data was analyzed with univariate and multivariate logistic regression analysis. Results Median age and weight of the patients were 150 days and 5.4 kgs respectively. The indications for ECMO were low cardiac output in 16, failure to wean cardiopulmonary bypass in 13, cardiac arrest in 10 and cardio-respiratory failure in 14 patients. The mean duration of ECMO was 143 hours. Weaning off from ECMO was successful in 66% and of these 83% were survival to hospital-discharge. 37.7% of patients were alive for the mean follow-up period of 75 months. On univariate analysis, arrhythmias, ECMO duration >168 hours, bleeding complications, renal replacement therapy on ECMO, arrhythmias and cardiac arrest after ECMO were associated with hospital mortality. On multivariate analysis, abnormal neurology, bleeding complications and arrhythmias after ECMO were associated with hospital mortality. Extra and intra-thoracic cannulations were used in 79% and 21% of patients respectively and extra-thoracic cannulation had significantly less bleeding complications (p = 0.031. Conclusion ECMO provides an effective circulatory support following surgical repair of CCD in children. Extra-thoracic cannulation is associated with less bleeding complications. Abnormal neurology, bleeding complications on ECMO and arrhythmias after ECMO are poor prognostic indicators for hospital survival.

Making electronic health records support quality management: A narrative review.

Triantafillou, Peter

2017-08-01

Since the 1990s many hospitals in the OECD countries have introduced electronic health record (EHR) systems. A number of studies have examined the factors impinging on EHR implementation. Others have studied the clinical efficacy of EHR. However, only few studies have explored the (intermediary) factors that make EHR systems conducive to quality management (QM). Undertake a narrative review of existing studies in order to identify and discuss the factors conducive to making EHR support three dimensions of QM: clinical outcomes, managerial monitoring and cost-effectiveness. A narrative review of Web of Science, Cochrane, EBSCO, ProQuest, Scopus and three Nordic research databases. most studies do not specify the type of EHR examined. 39 studies were identified for analysis. 10 factors were found to be conducive to make EHR support QM. However, the contribution of EHR to the three specific dimensions of QM varied substantially. Most studies (29) included clinical outcomes. However, only half of these reported EHR to have a positive impact. Almost all the studies (36) dealt with the ability of EHR to enhance managerial monitoring of clinical activities, the far majority of which showed a positive relationship. Finally, only five dealt with cost-effectiveness of which two found positive effects. The findings resonates well with previous reviews, though two factors making EHR support QM seem new, namely: political goals and strategies, and integration of guidelines for clinical conduct. Lacking EHR type specification and diversity in study method imply that there is a strong need for further research on the factors that may make EHR may support QM. Copyright © 2017 Elsevier B.V.

To investigate the support needs of elderly patients with diabetes and to classify elderly patients with diabetes living alone on the basis of support needs. Support needs were derived from a literature review of relevant journals and interviews of outpatients as well as expert nurses in the field of diabetes to prepare a 45-item questionnaire. Each item was analyzed on a 4-point Likert scale. The study included 634 elderly patients with diabetes who were recruited from 3 hospitals in Japan. Exploratory factor analysis was performed to determine the underlying structure of support needs, followed by hierarchical cluster analysis to clarify the characteristics of patients living alone (n=104) who had common support needs. Exploratory factor analysis suggested a 5-factor solution with 23 items: (1) hope for class and gatherings, (2) hope for personal advice including emergency response, (3) supportlessness and hopelessness, (4) barriers to food preparation, (5) hope of safe medical therapy. The hierarchical cluster analysis of subjects yielded 7 clusters, including a no special-support needs group, a collective support group, a self-care support group, a personal-support focus group, a life-support group, a food-preparation support group and a healthcare-environment support group. The support needs of elderly patients with diabetes who live alone can be divided into 2 categories: life and self-care support. Implementation of these categories in outpatient-management programs in which contact time with patients is limited is important in the overall management of elderly patients with diabetes who are living alone.

The aim of the current study was to examine the reliability and validity of a trait-based assessment of borderline personality disorder (BPD) using the NEO Five-Factor Inventory. Correlations between the Five-Factor Inventory-BPD composite (FFI-BPD) and explicit measures of BPD were examined across six samples, including undergraduate, community, and clinical samples. The median correlation was .60, which was nearly identical to the correlation between measures of BPD and a BPD composite generated from the full Revised NEO Personality Inventory (i.e., NEO-BPD; r =.61). Correlations between FFI-BPD and relevant measures of psychiatric symptomatology and etiology (e.g., childhood abuse, drug use, depression, and personality disorders) were also examined and compared to those generated using explicit measures of BPD and NEO-BPD. As expected, the FFI-BPD composite correlated most strongly with measures associated with high levels of Neuroticism, such as depression, anxiety, and emotion dysregulation, and the pattern of correlations generated using the FFI-BPD was highly similar to those generated using explicit measures of BPD and NEO-BPD. Finally, genetic analyses estimated that FFI-BPD is 44% heritable, which is comparable to meta-analytic research examining genetics associated with BPD, and revealed that 71% of the genetic influences are shared between FFI-BPD and a self-report measure assessing BPD (Personality Assessment Inventory – Borderline subscale; Morey, 1991). Generally, these results support the use of FFI-BPD as a reasonable proxy for BPD, which has considerable implications, particularly for potential gene-finding efforts in large, epidemiological datasets that include the NEO FFI.

Several options are advocated by policy experts to mitigate alcohol-related harms, although the most effective strategies often have the least public support. While knowledge of tobacco-related health risks predicts support for relevant public health measures, it is not known whether knowledge of alcohol health risks is similarly associated with the acceptability of policies intended to reduce alcohol consumption and related harms. This study aims to gauge public support for a range of alcohol policies and to determine whether or not support is associated with knowledge of a long-term health risk of alcohol consumption, specifically cancer. 2482 adults in New South Wales (NSW), Australia, participated in an online survey. Logistic regression analysis was used to examine the association between demographic data, alcohol consumption, smoking status, knowledge of alcohol as a risk factor for cancer and support for alcohol-related policies. Most participants were supportive of health warnings, restricting access to internet alcohol advertising to young people, and requiring information on national drinking guidelines on alcohol containers. Almost half of participants supported a ban on sport sponsorship, while less than 41% supported price increases, volumetric taxation, or reducing the number of retail outlets. Only 47% of participants identified drinking too much alcohol as a risk factor for cancer. Knowledge of alcohol as a risk factor for cancer was a significant predictor of support for all policies, while level of alcohol consumption had a significant inverse relationship with policy support. The finding that support for alcohol management policies is associated with awareness that drinking too much alcohol may contribute to cancer could assist in the planning of future public health interventions. Improving awareness of the long term health risks of alcohol consumption may be one avenue to increasing public support for effective alcohol harm-reduction policies

2013-01-01

To raise professional awareness of factors that may influence the support offered by clinicians to people with acquired brain injury (ABI), and to consider the potential implications of these factors in terms of post-injury rehabilitation and living. A review of the literature was conducted to identify factors that determine how clinicians provide support and influence opportunities for individuals with ABI to participate in decision making across the rehabilitation continuum. Clinical case studies are used to highlight two specific issues: (1) hidden assumptions on the part of the practitioner, and (2) perceptions of risk operating in clinical practice. There are a range of factors which may influence the decision-making support provided by clinicians and, ultimately, shape lifetime outcomes for individuals with ABI. A multidimensional framework may assist clinicians to identify relevant factors and consider their potential implications including those that influence how clinicians involved in supporting decision making approach this task. Participation in decision making is an undisputed human right and central to the provision of person-centred care. Further research is required to understand how clinical practice can maximise both opportunities and support for increased decision-making participation by individuals with ABI. There is an increasing focus on the rights of all individuals to be supported to participate in decision making about their life. A number of changes associated with ABI mean that individuals with ABI will require support with decision making. Clinicians have a critical role in providing this support over the course of the rehabilitation continuum. Clinicians need to be aware of the range of factors that may influence the decision-making support they provide. A multidimensional framework may be used by clinicians to identify influences on the decision-making support they provide.

Technological and organisational advances have increased the potential for remote access and proactive monitoring of the infrastructure in various domains and sectors - water and sewage, oil and gas and transport. Intelligent Infrastructure (II) is an architecture that potentially enables the generation of timely and relevant information about the state of any type of infrastructure asset, providing a basis for reliable decision-making. This paper reports an exploratory study to understand the concepts and human factors associated with II in the railway, largely drawing from structured interviews with key industry decision-makers and attachment to pilot projects. Outputs from the study include a data-processing framework defining the key human factors at different levels of the data structure within a railway II system and a system-level representation. The framework and other study findings will form a basis for human factors contributions to systems design elements such as information interfaces and role specifications.

OBJECTIVE To estimate how social support and social conflict relate to prenatal depressive symptoms and to generate a brief clinical tool to identify women at increased psychosocial risk. METHODS This is a prospective study following 1,047 pregnant women receiving care at two university-affiliated clinics from early pregnancy through 1 year postpartum. Structured interviews were conducted in the second trimester of pregnancy. Hierarchical and logistic regressions were used to examine potential direct and interactive effects of social support and conflict on prenatal depressive symptoms measured by the Center for Epidemiologic Studies-Depression Scale. RESULTS Thirty-three percent of the sample reported elevated levels of depressive symptoms predicted from sociodemographic factors, social support, and social conflict. Social support and conflict had independent effects on depressive symptoms although social conflict was a stronger predictor. There was a “dose–response,” with each increase in interpersonal risk factor resulting in consequent risk for probable depression based on symptom reports (Center for Epidemiologic Studies-Scale greater than or equal to 16). A composite of one social support and three conflict items were identified to be used by clinicians to identify interpersonal risk factors for depression in pregnancy. Seventy-six percent of women with a composite score of three or more high-risk responses reported depressive symptoms. CONCLUSION Increased assessment of social support and social conflict by clinicians during pregnancy can identify women who could benefit from group or individual interventions to enhance supportive and reduce negative social interactions.

What can stimulus polarity and interphase gap tell us about auditory nerve function in cochlear-implant recipients?

Science.gov (United States)

Hughes, Michelle L; Choi, Sangsook; Glickman, Erin

2018-03-01

Modeling studies suggest that differences in neural responses between polarities might reflect underlying neural health. Specifically, large differences in electrically evoked compound action potential (eCAP) amplitudes and amplitude-growth-function (AGF) slopes between polarities might reflect poorer peripheral neural health, whereas more similar eCAP responses between polarities might reflect better neural health. The interphase gap (IPG) has also been shown to relate to neural survival in animal studies. Specifically, healthy neurons exhibit larger eCAP amplitudes, lower thresholds, and steeper AGF slopes for increasing IPGs. In ears with poorer neural survival, these changes in neural responses are generally less apparent with increasing IPG. The primary goal of this study was to examine the combined effects of stimulus polarity and IPG within and across subjects to determine whether both measures represent similar underlying mechanisms related to neural health. With the exception of one measure in one group of subjects, results showed that polarity and IPG effects were generally not correlated in a systematic or predictable way. This suggests that these two effects might represent somewhat different aspects of neural health, such as differences in site of excitation versus integrative membrane characteristics, for example. Overall, the results from this study suggest that the underlying mechanisms that contribute to polarity and IPG effects in human CI recipients might be difficult to determine from animal models that do not exhibit the same anatomy, variance in etiology, electrode placement, and duration of deafness as humans.

The aim of the study was to explore the prevalence and risk factors for technical-induced hemolysis in adults supported with veno-venous extracorporeal membrane oxygenation (vvECMO) and to analyze the effect of hemolytic episodes on outcome. This was a retrospective, single-center study that included 318 adult patients (Regensburg ECMO Registry, 2009-2014) with acute respiratory failure treated with different modern miniaturized ECMO systems. Free plasma hemoglobin (fHb) was used as indicator for hemolysis. Throughout a cumulative support duration of 4,142 days on ECMO only 1.7% of the fHb levels were above a critical value of 500 mg/l. A grave rise in fHb indicated pumphead thrombosis (n = 8), while acute oxygenator thrombosis (n = 15) did not affect fHb. Replacement of the pumphead normalized fHb within two days. Neither pump or cannula type nor duration on the first system was associated with hemolysis. Multiple trauma, need for kidney replacement therapy, increased daily red blood cell transfusion requirements, and high blood flow (3.0-4.5 L/min) through small-sized cannulas significantly resulted in augmented blood cell trauma. Survivors were characterized by lower peak levels of fHb [90 (60, 142) mg/l] in comparison to non-survivors [148 (91, 256) mg/l, p≤0.001]. In conclusion, marked hemolysis is not common in vvECMO with modern devices. Clinically obvious hemolysis often is caused by pumphead thrombosis. High flow velocity through small cannulas may also cause technical-induced hemolysis. In patients who developed lung failure due to trauma, fHb was elevated independantly of ECMO. In our cohort, the occurance of hemolysis was associated with increased mortality.

Supported decision making has received increased attention as an alternative to guardianship and a means to enable people with intellectual and developmental disabilities to exercise their right to legal capacity. Assessments are needed that can used by people with disabilities and their systems of supports to identify and plan for needed supports to enable decision making. This article describes the steps taken to develop such an assessment tool, the Supported Decision Making Inventory System (SDMIS), and initial feedback received from self-advocates with intellectual disability. The three sections of the SDMIS (Supported Decision Making Personal Factors Inventory, Supported Decision Making Environmental Demands Inventory, and Decision Making Autonomy Inventory) are described and implications for future research, policy, and practice are discussed.

The purpose of this analysis is to evaluate the factors affecting the longevity of emplacement drift ground support materials and to develop a basis for the selection of materials for ground support that will function throughout the preclosure period of a potential repository at Yucca Mountain. The Development Plan (DP) for this analysis is given in Longevity of Emplacement Drift Ground Support Materials (CRWMS M and O 1999a). The objective of this analysis is to update the previous analysis (CRWMS M and O 2000a) to account for related changes in the Ground Control System Description Document (CRWMS M and O 2000b), the Monitored Geologic Repository Project Description Document (CRWMS M and O 1999b), and in environmental conditions, and to provide updated information on candidate ground support materials. Candidate materials for ground support are carbon steel and cement grout. Steel is mainly used for steel sets, lagging, channel, rock bolts, and wire mesh. Cement grout is only considered in the case of grouted rock bolts. Candidate materials for the emplacement drift invert are carbon steel and crushed rock ballast. Materials are evaluated for the repository emplacement drift environment based on the updated thermal loading condition and waste package design. The analysis consists of the following tasks: (1) Identify factors affecting the longevity of ground support materials for use in emplacement drifts; (2) Review existing documents concerning the behavior of candidate ground support materials during the preclosure period; (3) Evaluate impacts of temperature and radiation effects on mechanical and thermal properties of steel. Assess corrosion potential of steel at emplacement drift environment; (4) Evaluate factors affecting longevity of cement grouts for fully grouted rock bolt system. Provide updated information on cement grout mix design for fully grouted rock bolt system; and (5) Evaluate longevity of materials for the emplacement drift invert

The efficiency of these mechanisms is analysed in the paper. Overview of cogeneration development in Estonia is given with the focus on wood-fired cogeneration. Legislation acts and amendments, related to cogeneration support schemes, were described. For evaluating the efficiency of support mechanisms an indicator - fuel cost factor was defined. This indicator includes the costs related to the chosen fuel influence on the final electricity generation costs without any support mechanisms. The wood fuel cost factors were compared with the fuel cost factors for peat and oil shale. For calculating the fuel cost factors, various data sources were used. The fuel prices data were based on the average cost of fuels in Estonia for the period from 2000 till 2008. The data about operating and maintenance costs, related to the fuel type in the case of comparing wood fuel and oil shale fuel were taken from the CHP Balti and Eesti reports. The data about operating and maintenance costs used for peat and wood fuel comparison were taken from the Tallinn Elektrijaam reports. As a result, the diagrams were built for comparing wood and its competitive fuels. The decision boundary lines were constructed on the diagram for the situation, when no support was provided for wood fuels and for the situations, when various support mechanisms were provided during the last 12 years.

This study tests the inclusion of social support as a distinct exogenous variable in the Biobehavioral Family Model (BBFM). The BBFM is a biopsychosocial approach to health that proposes that biobehavioral reactivity (anxiety and depression) mediates the relationship between family emotional climate and disease activity. Data for this study included married, English-speaking adult participants (n = 1,321; 55% female; M age = 45.2 years) from the National Comorbidity Survey Replication, a nationally representative epidemiological study of the frequency of mental disorders in the United States. Participants reported their demographics, marital functioning, social support from friends and relatives, anxiety and depression (biobehavioral reactivity), number of chronic health conditions, and number of prescription medications. Confirmatory factor analyses supported the items used in the measures of negative marital interactions, social support, and biobehavioral reactivity, as well as the use of negative marital interactions, friends' social support, and relatives' social support as distinct factors in the model. Structural equation modeling indicated a good fit of the data to the hypothesized model (χ(2)  = 846.04, p = .000, SRMR = .039, CFI = .924, TLI = .914, RMSEA = .043).

KSC has used cryogenic life support (liquid air based) technology successfully for many years to support spaceflight operations. This technology has many benefits unique to cryogenics when compared to traditional compressed gas systems: passive cooling, lighter, longer duration, and lower operating pressure. However, there are also several limiting factors that have prevented the technology from being commercialized. The National Institute of Occupational Safety and Health, Office of Mine Safety and Health Research (NIOSH-OMSHR) has partnered with NASA to develop a complete liquid air based life support solution for emergency mine escape and rescue. The project will develop and demonstrate various prototype devices and incorporate new technological innovations that have to date prevented commercialization.

There is growing interest in characterising factors associated with positive regulatory outcomes for drug marketing authorisations. We assessed empirical studies published over the past 15 years seeking to identify predictive factors. Factors were classified to one of four 'factor clusters': evidentiary support; product or indication characteristics; company experience or strategy; social and regulatory factors. We observed a heterogeneous mix of technical factors (e.g., study designs, clinical evidence of efficacy) and less studied social factors (e.g., company-regulator interactions). We confirmed factors known to be of relevance to drug approval decisions (imperative) and a cohort of less understood (compensatory) social factors. Having robust supportive clinical evidence, addressing rare or serious illness, following scientific advice and prior company experience were associated with positive outcomes, which illustrated the multifactorial nature of regulatory decision making and factors need to be considered holistically while having varying, context-dependent importance.

Activation of factor VII bound to tissue factor: A key early step in the tissue factor pathway of blood coagulation

International Nuclear Information System (INIS)

Rao, L.V.M.; Rapaport, S.I.

1988-01-01

Whether the factor VII/tissue factor complex that forms in tissue factor-dependent blood coagulation must be activated to factor VIIa/tissue factor before it can activate its substrates, factor X and IX, has been a difficult question to answer because the substrates, once activated, back-activate factor VII. The earlier studies suggested that human factor VII/tissue factor cannot activate factor IX. Studies have now been extended to the activation of factor X. Reaction mixtures were made with purified factor VII, X, and tissue factor; in some experiments antithrombin III and heparin were added to prevent back-activation of factor VII. Factor X was activated at similar rates in reaction mixtures containing either VII or factor VIIa after an initial 30-sec lag with factor VII. In reaction mixtures with factor VII a linear activation of factor X was established several minutes before cleavage of 125 I-labeled factor VII to the two-chain activated molecule was demonstrable on gel profiles. These data suggest that factor VII/tissue factor cannot activate measurable amounts of factor X over several minutes. Overall, the results support the hypothesis that a rapid preferential activation of factor VII bound to tissue factor by trace amounts of factor Xa is a key early step in tissue factor-dependent blood coagulation

High-dose therapy with autologous marrow support results in durable complete remissions in selected patients with relapsed lymphoma and leukemia who cannot be cured with conventional dose therapy. However, substantial morbidity and mortality result from the 3- to 6-week period of marrow aplasia until the reinfused marrow recovers adequate hematopoietic function. Hematopoietic growth factors, particularly used after chemotherapy, can increase the number of peripheral blood progenitor cells (PBPCs) present in systemic circulation. The reinfusion of PBPCs with marrow has recently been reported to reduce the time to recovery of adequate marrow function. This study was designed to determine whether granulocyte-macrophage colony-stimulating factor (GM-CSF)-mobilized PBPCs alone (without marrow) would result in rapid and reliable hematopoietic reconstitution. Sixteen patients with metastatic breast cancer were treated with four cycles of doxorubicin, 5-fluorouracil, and methotrexate (AFM induction). Patients responding after the first two cycles were administered GM-CSF after the third and fourth cycles to recruit PBPCs for collection by two leukapheresis per cycle. These PBPCs were reinfused as the sole source of hematopoietic support after high doses of cyclophosphamide, thiotepa, and carboplatin. No marrow or hematopoietic cytokines were used after progenitor cell reinfusion. Granulocytes greater than or equal to 500/microL was observed on a median of day 14 (range, 8 to 57). Transfusion independence of platelets greater than or equal to 20,000/microL occurred on a median day of 12 (range, 8 to 134). However, three patients required the use of a reserve marrow for slow platelet engraftment. In retrospect, these patients were characterized by poor baseline bone marrow cellularity and poor platelet recovery after AFM induction therapy. When compared with 29 historical control patients who had received the same high-dose intensification chemotherapy using autologous

Full Text Available Breastfeeding rates in Sweden are declining, and it is important to identify women at risk for early cessation of exclusive breastfeeding.The aim of this study was to investigate factors associated with exclusive breastfeeding lasting less than two months postpartum.A population-based longitudinal study was conducted at Uppsala University Hospital, Sweden. Six hundred and seventy-nine women were included in this sub-study. Questionnaires were sent at five days, six weeks and six months postpartum, including questions on breastfeeding initiation and duration as well as several other background variables. The main outcome measure was exclusive breastfeeding lasting less than two months postpartum. Multivariable logistic regression analysis was used in order to calculate adjusted Odds Ratios (AOR and 95% Confidence Intervals (95% CI.Seventy-seven percent of the women reported exclusive breastfeeding at two months postpartum. The following variables in the multivariate regression analysis were independently associated with exclusive breastfeeding lasting less than two months postpartum: being a first time mother (AOR 2.15, 95% CI 1.32-3.49, reporting emotional distress during pregnancy (AOR 2.21, 95% CI 1.35-3.62 and giving birth by cesarean section (AOR 2.63, 95% CI 1.34-5.17.Factors associated with shorter exclusive breastfeeding duration were determined. Identification of women experiencing emotional distress during pregnancy, as well as scrutiny of caregiving routines on cesarean section need to be addressed, in order to give individual targeted breastfeeding support and promote longer breastfeeding duration.

Full Text Available Objective 　To develop Chinese Military Personnel Social Support Scaleand verify its reliability and validity. Methods 　The Chinese Military Personnel Social Support Scalewas initiated, organized and compiled based upon open-ended questionnaire survey done in a systematic manner, and previous researches were taken as references. A total of 630 military personnel were chosen by random cluster sampling and tested with the Scale, among them 50 were tested with Social Support Rating Scale(SSRS and Chinese Military Psychosomatic Health Scale(CMPHS simultaneously, and the test was done solely a second time with CMPHS 2 weeks later. The reliability and validity were assessed and verified by exploratory factor analysis, confirmatory factor analysis and correlation analysis. Results 　The Chinese Military Personnel Social Support Scalecomprised three factors, namely subjective support, objective support and utility of social support. Eighteen items were left in official scale after amendment by factor analysis, and one lying subscale was added. The correlation coefficients between the public factors ranged from 0.477 to 0.589 (P<0.01, and the correlation coefficients between factors and total scale ranged from 0.721 to 0.823 (P<0.01. The test-retest correlation coefficients of total scale and subscales ranged from 0.622 to 0.803 (P<0.01, the Cronbach α coefficients ranged from 0.624 to 0.874, and the split-half correlation coefficients ranged from 0.551 to 0.828. Significant correlation existed between this Scale and two criterion scales, namely SSRS and CMPHS. Conclusion 　It is verified that the Chinese Military Personnel Social Support Scalehas excellent reliability and validity, and complying with psychometric standards, it may be used to evaluate the social support level of Chinese military personnel.

Vulnerability Analysis of Soft Caving Tunnel Support System and Surrounding Rock Optimal Control Technology Research

Full Text Available The vulnerability assessment model, composed by 11 vulnerability factors, is established with the introduction of the concept of “vulnerability” into the assessment of tunnel support system. Analytic hierarchy process is utilized to divide these 11 factors into human attributes and natural attributes, and define the weight of these factors for the model. The “vulnerability” applied io the assessment of the tunnel support system model is reached. The vulnerability assessment model was used for evaluating and modifying the haulage tunnel #3207 of Bo-fang mine panel #2. The results decreased the vulnerability of the tunnel support system and demonstrated acceptable effects. Furthermore, the results show that the impact of human attributes on tunnel support systems is dramatic under the condition that natural attributes are permanent, and the “vulnerability” is exactly a notable factor to manifest the transformation during this process. The results also indicate that optimizing human attributes can attenuate vulnerability in tunnel support systems. As a result, enhancement of stability of tunnel support systems can be achieved.

Full Text Available While therapeutically interesting, the injection of MSCs suffers major limitations including cell death upon injection and a massive leakage outside the injection site. We proposed to entrap MSCs within spherical particles derived from alginate, as a control, or from silanized hydroxypropyl methylcellulose (Si-HPMC. We developed water in an oil dispersion method to produce small Si-HPMC particles with an average size of about 68 μm. We evidenced a faster diffusion of fluorescein isothiocyanate-dextran in Si-HPMC particles than in alginate ones. Human adipose-derived MSCs (hASC were encapsulated either in alginate or in Si-HPMC, and the cellularized particles were cultured for up to 1 month. Both alginate and Si-HPMC particles supported cell survival, and the average number of encapsulated hASC per alginate and Si-HPMC particle (7102 and 5100, resp. did not significantly change. The stimulation of encapsulated hASC with proinflammatory cytokines resulted in the production of IDO, PGE2, and HGF whose concentration was always higher when cells were encapsulated in Si-HPMC particles than in alginate ones. We have demonstrated that Si-HPMC and alginate particles support hASC viability and the maintenance of their ability to secrete therapeutic factors.

NMR line broadening in solids by slowing down of spin fluctuations

The 109 Ag nuclear magnetic resonance line in a sample of polycrystalline AgF is observed to broaden substantially when the 19 F spins are irradiated near the magic angle in their rotating frame. This is due to the reduction of 19 F- 19 F dipolar coupling, which normally causes fluctuations in the 19 F- 109 Ag interactions (Abragam and Winter), inducing an exchange narrowing analogous to classical motional narrowing. The 109 Ag linewidths obtained over the entire motional range at different 19 F frequencies are compared with those calculated exactly from the ratio of second to fourth moment. (orig.) [de

In the case of workers with disabilities, family support is often essential to gain access to the labor market and achieve personal autonomy and financial independence, in addition to fostering job satisfaction and permanence in the organization. Moreover, the support offered by organizations is particularly valued by workers with disabilities, as the organizations that hire such people generally go to considerable lengths to ensure their adaptation and integration in the workplace, contributing to job satisfaction and permanence in the organization. The aim of this study is to investigate the relationships between organizational support and family support with job satisfaction and intention to quit the organization among workers with disabilities employed in ordinary firms. Our study surveyed 204 workers using a questionnaire, and we used Structural Equation Modeling (SEM) analyses to test these relationships. Our results show that organizational support is a significant explanatory factor in the levels of job satisfaction. Moreover, our results indicate that the participants perceived high levels of support from their families, facilitating the conciliation of work and family life. Our results have practical implications in order to improve full integration and normalization of workers with disabilities in ordinary jobs.

The current study presents the development and the evaluation of the psychometric properties of the Cancer Perceived Agents of Social Support (CPASS). The CPASS is a new self-rating instrument devised in order to enable both cancer patients and their spouses to report on the level of perceived social support they get. The CPASS evaluates the support given by different agents of support (spouse, family, friends and spiritual or religious beliefs) in several dimensions (emotional, cognitive and instrumental). The study sample comprised 662 cancer patients and their spouses recruited during a routine medical evaluation from three major cancer centers in Israel. The participants completed the CPASS and two other standardized instruments: The ENRICH Marital Satisfaction Scale (EMS) and the Brief Symptom Inventory (BSI). Principal component analysis confirmed a three-factor structure based upon the agent of support (spouse; friends/family; spiritual/religious beliefs). Cronbach's α coefficients for the agent of support indexes were high (0.80-0.95), while Cronbach's α levels for the kind of support were lower (0.45-0.72). Smallest Space Analysis (SSA) also confirmed the theoretical structure of the CPASS. Pearson correlation coefficients to the other study variables were high and significant. As a whole, the CPASS was found to be a valid tool for the current Israeli sample. Theoretical and practical conclusions and socio-cultural implications are discussed.

To explore the availability and utilization of workplace health supports by employees of small and large-sized employers. Cross-sectional, telephone-based interviews collected on 16 workplace health supports for physical activity and diet. Participants selected by random-digit-dialing from 4 metropolitan areas of Missouri employees from 2012 to 2013. Two thousand fifteen working adults. We explored the availability and use of supports by employer size (employees vs ≥100 employees), accounting for industry and personal factors. We examined distributions and Poisson regression models of availability for supports by employer size and by industry and use of supports by employer size and personal factors. One-fifth of the 1796 employees were employed by small-sized employers. Large employers offered more supports than small (mean: 6 vs 3), but a higher proportion of employees of small-sized employers used supports when available (59% vs 47%). The differences in offered supports between industries were not due to size alone. In regard to the determinants of participation, the personal factors of gender, age, weight, and income were associated with participation in 10 of the supports. Employer size was also associated with participation in 10 supports. No associations were found between personal factors or workplace size and participation for 3 supports. A higher proportion of employees working for smaller businesses use available supports than employees of larger businesses. Supports offered by employers should target the needs and interests of the workforce, particularly for the higher risk low-income employees.

Simplified piping analysis methods with inelastic supports

Lin, C.W.; Romanko, A.D.

1986-01-01

Energy absorbing supports (EAS) which contain x-shaped plates or dampers with heavy viscous fluid can absorb a large amount of energy during vibratory motions. The response of piping systems supported by these types of energy absorbing devices can be markedly reduced as compared with ordinary supports using rigid rods, hangers or snubbers. In this paper, a simple multiple support response spectrum technique is presented, which would allow the energy dissipation nature of the EAS be factored in the piping response calculation. In the meantime, the effect of lower system frequencies due to the reduced support stiffness from local yielding is also included in the analysis. Numerical results obtained show that this technique is more conservative than the time history solution by an acceptable and realistic margin; and it has less than 10 percent of the computation cost

2003-12-01

The purpose of this study was to develop and evaluate the psychometric properties of 2 supportive leadership scales, the Charge Nurse Support Scale and the Unit Manager Support Scale, designed for long-term-care environments. These 6-item self-report scales were administered to 70 nursing staff and their internal consistency reliability, test-retest reliability, content validity, factor structure, and construct validity investigated. Content validity was established with the assistance of experts. Both scales were deemed reliable. As hypothesized, a significant relationship was found between the measure of how nursing staff related to residents and measures of charge nurses' supportive behaviours (r = .42, p = .05). Reliable and valid measures of supportive leadership could be developed for use in identifying the quality of support provided to staff in long-term-care environments.

Loneliness and social support of older people in China: a systematic literature review.

Loneliness is a serious problem for older people, which can be alleviated by social support. The dramatic population ageing together with social and economic change in China increases the likelihood of loneliness and the availability of different sources of social support of older people. The aim of this review was to identify the prevalence of loneliness and its related factors and sources of social support of older people in China. Electronic literature searches were conducted in September 2011 using Web of Science, PsycINFO, MEDLINE, PubMed, CINAHL, China Academic Journal and VIP Database for Chinese Technical Periodicals. Twenty-six papers were identified and reviewed. The prevalence of loneliness varied across the studies, reflecting the different measurements and samples. Marital status, gender, age, educational level, economic level, living arrangements, health status and social support were significant factors related to loneliness. The family was the most important source of social support followed by friends. The receipt of family support improved subjective well-being and mental health, but the effects of support from friends were inconsistent. Chinese older people received relatively little support from neighbours, governmental or other social organisations. Further well-designed studies are needed to identify additional factors related to loneliness and to understand the support from friends, neighbours, formal organisations and other sources. © 2013 John Wiley & Sons Ltd.

The paper presents the design of PGV-1000M steam generator support. It is shown that the load in the rolling support is distributed extremely unevenly, which is associated with the compliance of the support construction. It is demonstrated that under working loads only several rollers are used, the stresses in which exceed the yield strength. This can be an additional loading factor to be considered in the analysis of welding No. 111 failure.

In micromechanical resonators, energy loss via supports into the substrates may lead to a low quality factor. To eliminate the support loss, in this paper a phononic band-gap structure is employed. We demonstrate a design of phononic-crystal (PC) strips used to support extensional wine-glass mode ring resonators to increase the quality factor. The PC strips are introduced to stop elastic-wave propagation by the band-gap and deaf-band effects. Analyses of resonant characteristics of the ring resonators and the dispersion relations, eigenmodes, and transmission properties of the PC strips are presented. With the proposed resonator architecture, the finite-element simulations show that the leaky power is effectively reduced and the stored energy inside the resonators is enhanced simultaneously as the operating frequencies of the resonators are within the band gap or deaf bands. Realization of a high quality factor micromechanical ring resonator with minimized support loss is expected.

Full Text Available Orientation: Currently there is much debate whether modifying traditional reward packages to focus on the preferences of multi-generations would be essential in attracting, motivating and retaining talent. Total reward factors, perceived organisational support and perceived supervisor support are distinct but related concepts, all of which appear to influence an employee’s decision to stay at an organisation. Research purpose: The objective of this study was to identify the different total reward components that multi-generations prefer as most important for retention. In essence, the study aims to establish possible relationships between multi-generations’ total reward components, perceived organisational support, and perceived supervisor support. Motivation for the study: This study is useful as it conducts a contemporary retention exploration that considers both the emerging demographic workforce shift and the new paradigm shift towards talent management. Research methodology: A quantitative, cross-sectional research design was applied to gather data from employees (N = 303 from different industry sectors in South African organisations. Main findings: The results showed that performance management and remuneration are considered to be the most important retention factors amongst multi-generation groups. Differences between total reward preferences and demographical variables, which include age, gender, race, industry and job level, were found. Practical/managerial implications: Organisations should design their reward packages by taking employees preferences into account. More specifically, organisations should focus on remuneration, performance management and development opportunities in order to retain scarce skills. Contribution/value additions: The results of the study can assist managers to design effective retention strategies, whilst also providing crucial information for the retention and motivation of employees.

Wilks, Scott E; Croom, Beth

2008-05-01

The study examined whether social support functioned as a protective, resilience factor among Alzheimer's disease (AD) caregivers. Moderation and mediation models were used to test social support amid stress and resilience. A cross-sectional analysis of self-reported data was conducted. Measures of demographics, perceived stress, family support, friend support, overall social support, and resilience were administered to caregiver attendees (N=229) of two AD caregiver conferences. Hierarchical regression analysis showed the compounded impact of predictors on resilience. Odds ratios generated probability of high resilience given high stress and social supports. Social support moderation and mediation were tested via distinct series of regression equations. Path analyses illustrated effects on the models for significant moderation and/or mediation. Stress negatively influenced and accounted for most variation in resilience. Social support positively influenced resilience, and caregivers with high family support had the highest probability of elevated resilience. Moderation was observed among all support factors. No social support fulfilled the complete mediation criteria. Evidence of social support as a protective, moderating factor yields implications for health care practitioners who deliver services to assist AD caregivers, particularly the promotion of identification and utilization of supportive familial and peer relations.

Full Text Available To ensure success of students enrolled in distance learning courses factors such as training for instructors, allocation of resources, administrative support, perceived relevance of content to the student's career or personal interests, degree of student support, amount and nature of feedback and amount of time/effort required as well as establishment of learning communities are critical. Unfortunately, these services are not always in place when colleges first begin to venture into distance education. In addition, faculty members are often reluctant to develop courses in the absence of sufficient support from administrators and technical staff, not only for themselves, but their students as well. This article will discuss these issues and why they are important for student success.

To enable better psychosocial, informational, and practical support of Chinese patients with cancer, this study was conducted to identify the specific support needs of Chinese immigrant cancer patients. The Cancer Portal Project at Memorial Sloan-Kettering Cancer Center's Center for Immigrant Health and Cancer Disparities is a patient navigation program that assists underserved and minority cancer patients in obtaining social and economic assistance at ten New York City cancer clinics. This need assessment was conducted as part of the Portal Project. Sixty-four questions were added to the existing Portal Intake Form about the needs and preferences for Chinese-language support and survivorship services. Descriptive analysis was performed, as well as an exploratory principal component's factor analysis to determine if there were any patterns in the services and programs in which patients were interested. Ninety-six patients were approached for participation; 59 agreed to participate. Eighty-eight percent of participants were born in China. Ninety-seven percent preferred to speak Mandarin, Cantonese, or Fujianese in the healthcare setting. When asked about general interest in support programs, 53 % of the participants were "very interested," 27 % were "maybe interested," and 17 % were "not interested." Programs in which more participants were "very interested" included those that would provide information about obtaining financial assistance (79 %) and social assistance (74 %), information on treatment options (67 %), help in coping with the burden of illness on the family (65 %), and information about general healthcare (63 %). The factor analysis resulted in the identification of five factors: social/financial/treatment and care issues, nutrition and exercise/networking/general health care, coping with fear and stress, herbs and dietary supplements, and acupuncture and acupressure. In this study, 80 % of the participants expressed interest in programs tailored for

Full Text Available The aim of the study was to explore the prevalence and risk factors for technical-induced hemolysis in adults supported with veno-venous extracorporeal membrane oxygenation (vvECMO and to analyze the effect of hemolytic episodes on outcome. This was a retrospective, single-center study that included 318 adult patients (Regensburg ECMO Registry, 2009-2014 with acute respiratory failure treated with different modern miniaturized ECMO systems. Free plasma hemoglobin (fHb was used as indicator for hemolysis. Throughout a cumulative support duration of 4,142 days on ECMO only 1.7% of the fHb levels were above a critical value of 500 mg/l. A grave rise in fHb indicated pumphead thrombosis (n = 8, while acute oxygenator thrombosis (n = 15 did not affect fHb. Replacement of the pumphead normalized fHb within two days. Neither pump or cannula type nor duration on the first system was associated with hemolysis. Multiple trauma, need for kidney replacement therapy, increased daily red blood cell transfusion requirements, and high blood flow (3.0-4.5 L/min through small-sized cannulas significantly resulted in augmented blood cell trauma. Survivors were characterized by lower peak levels of fHb [90 (60, 142 mg/l] in comparison to non-survivors [148 (91, 256 mg/l, p≤0.001]. In conclusion, marked hemolysis is not common in vvECMO with modern devices. Clinically obvious hemolysis often is caused by pumphead thrombosis. High flow velocity through small cannulas may also cause technical-induced hemolysis. In patients who developed lung failure due to trauma, fHb was elevated independantly of ECMO. In our cohort, the occurance of hemolysis was associated with increased mortality.

Hotchkiss, Jason T; Lesher, Ruth

2018-06-01

This study predicted Burnout from the self-care practices, compassion satisfaction, secondary traumatic stress, and organizational factors among chaplains who participated from all 50 states (N = 534). A hierarchical regression model indicated that the combined effect of compassion satisfaction, secondary traumatic stress, mindful self-care, demographic, and organizational factors explained 83.2% of the variance in Burnout. Chaplains serving in a hospital were slightly more at risk for Burnout than those in hospice or other settings. Organizational factors that most predicted Burnout were feeling bogged down by the "system" (25.7%) and an overwhelming caseload (19.9%). Each self-care category was a statistically significant protective factor against Burnout risk. The strongest protective factors against Burnout in order of strength were self-compassion and purpose, supportive structure, mindful self-awareness, mindful relaxation, supportive relationships, and physical care. For secondary traumatic stress, supportive structure, mindful self-awareness, and self-compassion and purpose were the strongest protective factors. Chaplains who engaged in multiple and frequent self-care strategies experienced higher professional quality of life and low Burnout risk. In the chaplain's journey toward wellness, a reflective practice of feeling good about doing good and mindful self-care are vital. The significance, implications, and limitations of the study were discussed.

2016-08-01

WHAT IS KNOWN ON THE SUBJECT?: Despite the increased interest in nursing students' happiness in South Korea, few studies have attempted to identify factors influencing their happiness. Therefore, nursing educators should consistently investigate the factors influencing happiness and develop strategies to improve happiness among Korean nursing students. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study confirmed that there were positive correlations between grateful disposition, social support and happiness. In addition, grateful disposition and support from intimate people were identified as predictors of happiness in Korean nursing students. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Development of intervention programmes to help nursing students increase grateful disposition and support from intimate people may be helpful for improving happiness. These programmes can include activity, such as writing a gratitude journal, and extracurricular programmes, such as mentoring programmes between seniors and juniors and/or professor and student. Introduction Happiness is very important in the training and development of nursing students as future nurses. However, nursing students experience a high level of stress and low level of happiness in South Korea. Aim This study aimed to investigate factors that affect happiness among nursing students in South Korea. Method Data were collected from a total of 241 nursing enrolled in two 4-year baccalaureate nursing programmes in South Korea, using a self-administrated questionnaire. To identify predictors of happiness, stepwise regression analysis was conducted. Results The results indicated that grateful disposition and support from intimate people significantly predict happiness among Korean nursing students. These two factors accounted for 38.0% of the variance in happiness. Discussion This study indicated grateful disposition and support from intimate people as factors promoting happiness in nursing students. The findings

Access to health care often depends on where one lives. Rural populations have significantly poorer health outcomes than their urban counterparts. Specialist outreach to rural communities is one way of improving access to care. A multifaceted style of outreach improves access and health outcomes, whilst a shifted outpatients style only improves access. In principle, stakeholders agree that specialist outreach and support (O&S) to rural populations is necessary. In practice, however, factors influence whether or not O&S reaches its goals, affecting sustainability.Aim and setting: Our aim was to better understand factors associated with the success or failure of specialist O&S to rural populations in the Eden and Central Karoo districts in the Western Cape. An anonymous parallel three-stage Delphi process was followed to obtain consensus in a specialist and district hospital panel. Twenty eight specialist and 31 district hospital experts were invited, with response rates of 60.7%-71.4% and 58.1%-74.2% respectively across the three rounds. Relationships, communication and planning were found to be factors feeding into a service delivery versus capacity building tension, which affects the efficiency of O&S. The success of the O&S programme is dependent on a site-specific model that is acceptable to both the outreaching specialists and the hosting district hospital. Good communication, constructive feedback and improved planning may improve relationships and efficiency, which might lead to a more sustainable and mutually beneficial O&S system.

2017-01-01

Using virtual environments to assess complex large scale human tasks provides timely and cost effective results to evaluate designs and to reduce operational risks during assembly and integration of the Space Launch System (SLS). NASA's Marshall Space Flight Center (MSFC) uses a suite of tools to conduct integrated virtual analysis during the design phase of the SLS Program. Siemens Jack is a simulation tool that allows engineers to analyze human interaction with CAD designs by placing a digital human model into the environment to test different scenarios and assess the design's compliance to human factors requirements. Engineers at MSFC are using Jack in conjunction with motion capture and virtual reality systems in MSFC's Virtual Environments Lab (VEL). The VEL provides additional capability beyond standalone Jack to record and analyze a person performing a planned task to assemble the SLS at Kennedy Space Center (KSC). The VEL integrates Vicon Blade motion capture system, Siemens Jack, Oculus Rift, and other virtual tools to perform human factors assessments. By using motion capture and virtual reality, a more accurate breakdown and understanding of how an operator will perform a task can be gained. By virtual analysis, engineers are able to determine if a specific task is capable of being safely performed by both a 5% (approx. 5ft) female and a 95% (approx. 6'1) male. In addition, the analysis will help identify any tools or other accommodations that may to help complete the task. These assessments are critical for the safety of ground support engineers and keeping launch operations on schedule. Motion capture allows engineers to save and examine human movements on a frame by frame basis, while virtual reality gives the actor (person performing a task in the VEL) an immersive view of the task environment. This presentation will discuss the need of human factors for SLS and the benefits of analyzing tasks in NASA MSFC's VEL.

Full Text Available Reviews of programmes in Bangladesh, Benin, the Philippines, Sri Lanka, Uganda, and Uzbekistan sought to identify health policy and programmatic factors that influenced breastfeeding practices during a 10 to 15 year period. Exclusive breastfeeding rates and trends were analysed in six countries in general and from an equity perspective in two of them. Success factors and challenges were identified in countries with improved and stagnated rates respectively. The disaggregated data analysis showed that progress may be unequal in population subgroups, but if appropriately designed and implemented, a programme can become a “health equalizer” and eliminate discrepancies among different subgroups. Success requires commitment, supportive policies, and comprehensiveness of programmes for breastfeeding promotion, protection and support. Community-based promotion and support was identified as a particularly important component. Although health workers’ training on infant feeding support and counselling was prioritized, further improvement of interpersonal counselling and problem solving skills is needed. More attention is advised for pre-service education, including a stronger focus on clinical practice, to ensure knowledge and skills among all health workers. Large-scale communication activities played a significant role, but essential steps were often underemphasized, including identifying social norms and influencing factors, ensuring community participation, and testing of approaches and messages.

The current study investigated risk factors for suicidal ideation in a community sample of 392 adolescents (males 51.9 %; females 48.1 %), while also evaluating self-esteem, perceived parent support, and perceived peer support as protective factors and potential moderators between suicidal ideation and the 3 risk factors. Disordered eating, depression, parent support, and peer support were found to be significant predictors of current suicidal ideation, but body satisfaction was not. The relationship between depression and suicidal ideation was significantly moderated by both self-esteem and parent support, while the relationship between disordered eating and suicidal ideation was significantly moderated by peer support. Results underscore the importance of examining protective factors for suicide risk, as they have the potential to reduce suicidal ideation in adolescents.

Activation of human factor V by factor Xa and thrombin

Monkovic, D.D.; Tracy, P.B.

1990-01-01

The activation of human factor V by factor Xa and thrombin was studied by functional assessment of cofactor activity and sodium dodecyl sulfate-polycarylamide gel electrophoresis followed by either autoradiography of 125 I-labeled factor V activation products or Western blot analyses of unlabeled factor V activation products. Cofactor activity was measured by the ability of the factor V/Va peptides to support the activation of prothrombin. The factor Xa catalyzed cleavage of factor V was observed to be time, phospholipid, and calcium ion dependent, yielding a cofactor with activity equal to that of thrombin-activated factor V (factor Va). The cleavage pattern differed markedly from the one observed in the bovine system. The factor Xa activated factor V subunits expressing cofactor activity were isolated and found to consist of peptides of M r 220,000 and 105,000. Although thrombin cleaved the M r 220,000 peptide to yield peptides previously shown to be products of thrombin activation, cofactor activity did not increase. N-Terminal sequence analysis confirmed that both factor Xa and thrombin cleave factor V at the same bond to generate the M r 220,000 peptide. The factor Xa dependent functional assessment of 125 I-labeled factor V coupled with densitometric analyses of the cleavage products indicated that the cofactor activity of factor Xa activated factor V closely paralleled the appearance of the M r 220,000 peptide. The data indicate that factor Xa is as efficient an enzyme toward factor V as thrombin

Full Text Available Abstract Background Abstinence and responsible drinking are not typically associated with youth drinking culture. Amongst Pacific youth in New Zealand there are high numbers, compared to the general New Zealand population, who choose not to consume alcohol. The Pacific youth population is made up of several ethnic groups; their ethno-cultural values are largely Polynesian and heavily influenced by the socio-economic realities of living in New Zealand. This paper explores factors that support abstinence or responsible drinking amongst Pacific youth living in Auckland. Methods A qualitative study comprised of a series of ethnically-, age-, and gender-matched semi-structured focus group discussions with 69 Pacific youth, aged 15-25 years from a university and selected high-schools. Participants were purposively sampled. Results Key cultural factors that contributed to whether Pacific youth participants were abstinent or responsible drinkers were: significant experiences within Pacific family environments (e.g. young person directly links their decision about alcohol consumption to a positive or negative role model; awareness of the belief that their actions as children of Pacific parents affects the reputation and standing of their Pacific family and community (e.g. church; awareness of traditional Pacific values of respect, reciprocity and cultural taboos (e.g. male–female socialising; commitment to no-alcohol teachings of church or religious faith; having peer support and experiences that force them to consider negative effects of excessive alcohol consumption; and personal awareness that being part of an (excessive drinking culture may seriously affect health or impede career aspirations. Conclusions The narratives offered by Pacific young people highlighted three key communities of influence: family (immediate and extended, but especially siblings, peers and church. Young people negotiated through these communities of influence their

Cognitive and social factors are essential considerations in inflammatory bowel disease (IBD) patient management, but existing research is limited. This study aims to expand the IBD literature by examining the relationship between social supports and QoL, while examining mechanisms in these relationships. Consenting patients attending an IBD outpatient clinic were provided a survey package (N = 164). Regressions evaluated predictors of IBD-QoL, and catastrophizing and optimism were examined as mediators between social support and IBD-QoL. Diminished IBD-QoL was predicted by younger age, greater negative spousal responses, and less perceived spousal support. Mediation models showed helplessness catastrophizing to be the lone mediator, acting as a mechanism between both negative spousal responses and perceived spousal support with IBD-QoL. Social interaction variables are associated with IBD-QoL, but patients' experience of helplessness acts to reduce their ability to benefit from social support. Patient care should consider supportive social and cognitive factors to improve IBD-QoL.

Decisions to forgo life support from critically ill children are commonly faced by parents and physicians. Previous research regarding parents' perspectives on the decision-making process has been limited by retrospective methods and the use of closed-ended questionnaires. We prospectively identified and described parents' self-reported influences on decisions to forgo life support from their children. Deeper understanding of parents' views will allow physicians to focus end-of-life discussions on factors important to parents and help resolve conflicts. Prospective, qualitative pilot study. Pediatric intensive care unit of a university-affiliated children's hospital. A total of 14 parents of ten children whose pediatric intensive care unit physician had made a recommendation to limit or withdraw life support. : In-depth, semistructured interviews were conducted with parents during their decision-making process. Factors influencing the parents in this study in their decision to forgo life support included their previous experience with death and end-of-life decision making for others, their personal observations of their child's suffering, their perceptions of their child's will to survive, their need to protect and advocate for their child, and the family's financial resources and concerns regarding life-long care. Parents in this study expressed the desire to do what is best for their child but struggled with feelings of selfishness, guilt, and the need to avoid agony and sorrow. Physician recommendations, review of options, and joint formulation of a plan helped parents gain a sense of control over their situation. Parents of eight children agreed to forgo life support and parents of two did not. Prospective interviews with open-ended questions identified factors influencing parents' decision making not previously described in the critical care literature such as parents' past experiences with end-of-life decisions and their anticipated emotional adjustments and

Factor VII deficiency is the most common among the rare autosomal recessive coagulation disorders worldwide. In factor VII deficient patients, the severity and clinical manifestations cannot be reliably determined by factor VII levels. Severe bleeding tends to occur in individuals with factor VII activity levels of 2% or less of normal. Patients with 2-10% factor VII vary between asymptomatic to severe life threatening haemorrhages behaviour. Recombinant factor VIIa (rFVIIa) is the most common replacement therapy for congenital factor VII deficiency. However, unlike haemophilia patients for whom treatment protocols are straight forward, in asymptomatic factor VII deficiency patients it is still debatable. In this study, we demonstrate that a single and very low dose of recombinant factor VIIa enabled asymptomatic patients with factor VII deficiency to go through major surgery safely. This suggestion was also supported by thrombin generation, as well as by thromboelastometry.

Social support and vulnerability: state of the art in relation to families and children.

1984-01-01

The purpose of this presentation is to review the concepts of social support and vulnerable families and children, propose a theoretical model on coping and adaptation, and ascertain any significant implications for the delivery of health care services and future research. The review of the literature indicates that major problems persist in the classification, conceptualization, empirical investigation, and clinical application of social support due to a lack of clarity regarding the definition of social support and how it works. Related perspectives such as bonding, child development, and child rearing also reaffirm the need for and the utilization of social support. High-risk factors, such as low maternal age, poverty, single parenthood, and long-term health problems, increase the vulnerability of families and children. This literature strongly suggests that the interactions of adults and children with supportive members of their social networks are important in the development of essential cognitive and social skills, as well as for the promotion of security and comfort. Supports from individuals, families, and groups also are associated with more successful adaptation and favorable outcomes. Despite numerous articles and research projects, however, questions concerning how social support works to assist vulnerable children and families remain. Seven factors are proposed as a theoretical model to identify threatening situations and coping difficulties so that appropriate support can be provided. These factors are surprise, experience, confusion, perceived effectiveness, perceived allies, perceived uniqueness of threat, and overload. Additional testing is required for this model so that a more meaningful investigation and utilization of social support can be established. Additional research also is indicated to determine the specific types of support needed in the presence of certain factors, network style preferences, the supply and demand for support over the

Medical errors and unanticipated negative patient outcomes can damage the well-being of health care providers. These affected individuals, referred to as "second victims," can experience various psychological and physical symptoms. Support resources provided by health care organizations to prevent and reduce second victim-related harm are often inadequate. In this study, we present the development and psychometric evaluation of the Second Victim Experience and Support Tool (SVEST), a survey instrument that can assist health care organizations to implement and track the performance of second victim support resources. The SVEST (29 items representing 7 dimensions and 2 outcome variables) was completed by 303 health care providers involved in direct patient care. The survey collected responses on second victim-related psychological and physical symptoms and the quality of support resources. Desirability of possible support resources was also measured. The SVEST was assessed for content validity, internal consistency, and construct validity with confirmatory factor analysis. Confirmatory factor analysis results suggested good model fit for the survey. Cronbach α reliability scores for the survey dimensions ranged from 0.61 to 0.89. The most desired second victim support option was "A respected peer to discuss the details of what happened." The SVEST can be used by health care organizations to evaluate second victim experiences of their staff and the quality of existing support resources. It can also provide health care organization leaders with information on second victim-related support resources most preferred by their staff. The SVEST can be administered before and after implementing new second victim resources to measure perceptions of effectiveness.

Highly predictive support vector machine (SVM) models for anthrax toxin lethal factor (LF) inhibitors.

Science.gov (United States)

Zhang, Xia; Amin, Elizabeth Ambrose

2016-01-01

Anthrax is a highly lethal, acute infectious disease caused by the rod-shaped, Gram-positive bacterium Bacillus anthracis. The anthrax toxin lethal factor (LF), a zinc metalloprotease secreted by the bacilli, plays a key role in anthrax pathogenesis and is chiefly responsible for anthrax-related toxemia and host death, partly via inactivation of mitogen-activated protein kinase kinase (MAPKK) enzymes and consequent disruption of key cellular signaling pathways. Antibiotics such as fluoroquinolones are capable of clearing the bacilli but have no effect on LF-mediated toxemia; LF itself therefore remains the preferred target for toxin inactivation. However, currently no LF inhibitor is available on the market as a therapeutic, partly due to the insufficiency of existing LF inhibitor scaffolds in terms of efficacy, selectivity, and toxicity. In the current work, we present novel support vector machine (SVM) models with high prediction accuracy that are designed to rapidly identify potential novel, structurally diverse LF inhibitor chemical matter from compound libraries. These SVM models were trained and validated using 508 compounds with published LF biological activity data and 847 inactive compounds deposited in the Pub Chem BioAssay database. One model, M1, demonstrated particularly favorable selectivity toward highly active compounds by correctly predicting 39 (95.12%) out of 41 nanomolar-level LF inhibitors, 46 (93.88%) out of 49 inactives, and 844 (99.65%) out of 847 Pub Chem inactives in external, unbiased test sets. These models are expected to facilitate the prediction of LF inhibitory activity for existing molecules, as well as identification of novel potential LF inhibitors from large datasets.

Full Text Available Introduction: Social support is the perception that one is cared for, has assistance available from significant others and its benefit is by buffering stress by influencing the ability to adjust and live with illness. Social support can uplift the quality and subjective wellbeing of people. The objective of this study was to examine the perceived social support and factors influencing it among mentally ill patients. Methods: A descriptive cross-sectional study was carried out. Ninety cases aged more than 18 years visiting outpatient of psychiatric department and diagnosed as a case of mental illness for at least a year were included. Instruments used were self-developed proforma and Multidimensional Scale of Perceived Social Support. Interview technique was used to collect the data. Results: Majority (60% of the patients perceive social support from family, 28% of the patients perceive social support from significant others. Regression analysis showed that the perceived social support is influenced by employment status, type of family one lives in and physical illness. It is not influenced by gender, subjective financial status and frequency of hospitalization. Conclusion: Perceived social support is influenced by employment status, type of family one lives in and physical illness. Majority (60% of the patients perceive social support from family.

Full Text Available Capital is the main factor of production, business development becomes virtually impossible without taking into account the financial market and the resources it provides to businesses. Any business, regardless of its degree of development, is involving direct contact with financial markets, namely the institutions that mediate mobilization of capital and the services they provide. Understanding the functioning of the financial system, the specific financial mechanisms through which savings are allocated to support capital investments and the costs and risks involved is essential for the development of a solid base for business. In this context, factoring operations can support economic agents, allowing a transfer of commercial receivables from their holder to a factor who commits to their recovery and guarantee such operations even if temporary or permanent insolvency of the debtor . Thus, factoring is a complex technique in at least two aspects, of the debt and the transfer of credit. . Factoring is a means of financing business, especially export-import transactions, less known in Romania. Maybe because of poor business environment popularize the term is as little known as it was a few years ago the leasing. Present in Romanian legislation since 2002, factoring appears as a contract between one party (called adherent, providing goods or service and a banking company or a financial institution specialized (called factor, which the last one shall finance debts pursuing and preservation against credit risks and adherent gives factor by way of sale, debts arising from the sale of goods or services to third parties. The article is divided into three parts. In the first part we defined the concept of factoring and international factoring, then I presented the advantages and development of factoring in Romania, and the last part conclusions.

2018-05-21

A new measure, the Online Social Support Scale, was developed based on previous theory, research, and measurement of in-person social support. It includes four subscales: Esteem/Emotional Support, Social Companionship, Informational Support, and Instrumental Support. In college and community samples, factor analytic and item response theory results suggest that subtypes of in-person social support also pertain in the online world. Evidence of reliability, convergent validity, and discriminant validity provide excellent psychometric support for the measure. Construct validity accrues to the measure vis-à-vis support for three hypotheses: (a) Various broad types of Internet platforms for social interactions are differentially associated with online social support and online victimization; (b) similar to in-person social support, online social support offsets the adverse effect of negative life events on self-esteem and depression-related outcome; and (c) online social support counteracts the effects of online victimization in much the same way that in-person friends in one social niche counterbalance rejection in other social niches.

Anderson, Carina; Moxham, Lorna; Broadbent, Marc

2016-10-01

This discussion paper poses the question 'What enables or deters Registered Nurses to take up their professional responsibility to support undergraduate nursing students through the provision of clinical education?'. Embedded within many nursing standards are expectations that Registered Nurses provide support and professional development to undergraduate nursing students undertaking clinical placements. Expectations within nursing standards that Registered Nurses provide support and professional development to nursing students are important because nursing students depend on Registered Nurses to help them to become competent practitioners. Contributing factors that enable and deter Registered Nurses from fulfilling this expectation to support nursing students in their clinical learning include; workloads, preparedness for the teaching role, confidence in teaching and awareness of the competency requirement to support students. Factors exist which can enable or deter Registered Nurses from carrying out the licence requirement to provide clinical education and support to nursing students.

[Nutritional support in sepsis].

Ortiz Leyba, C; López Martínez, J; Blesa Malpica, A L

2005-06-01

Although it is considered that metabolic and nutritional support must be part of the management of septic patients, it has not been conclusively shown that nutritional support will improve survival or complications from sepsis. Specific data on this issue are scarce since there are few studies that have investigated specialized nutritional support in septic patients. Thus, most of the recommendations are based on outcomes obtained in severely ill patients with different pathologies. It is assumed that nutritional support should be carried out through the enteral route whenever possible, as in other critically ill patients. The energetic waste in these patients is highly variable, although in general terms the hypermetabolic situation may be classified as moderate. An adjustment factor of 1.25-1.30 is recommended for the Harris-Benedict's equation to calculate the caloric intake. Septic patients should receive a hyperproteic intake. The amount of glucose administered should not exceed 70% of non-protein calories, and lipids intake should not exceed 40%. With regards to micronutrients, it is recommended to increase the supply of those with antioxidant properties (vitamin E, carotenes, vitamin C, selenium). There are data to consider that the use of diets enriched with pharmaco-nutrients (both with parenteral and enteral routes) may be beneficial in septic patients, although there is some controversy when interpreting the outcomes.

Stochastic analysis of uncertain thermal parameters for random thermal regime of frozen soil around a single freezing pipe

2018-03-01

The artificial ground freezing method (AGF) is widely used in civil and mining engineering, and the thermal regime of frozen soil around the freezing pipe affects the safety of design and construction. The thermal parameters can be truly random due to heterogeneity of the soil properties, which lead to the randomness of thermal regime of frozen soil around the freezing pipe. The purpose of this paper is to study the one-dimensional (1D) random thermal regime problem on the basis of a stochastic analysis model and the Monte Carlo (MC) method. Considering the uncertain thermal parameters of frozen soil as random variables, stochastic processes and random fields, the corresponding stochastic thermal regime of frozen soil around a single freezing pipe are obtained and analyzed. Taking the variability of each stochastic parameter into account individually, the influences of each stochastic thermal parameter on stochastic thermal regime are investigated. The results show that the mean temperatures of frozen soil around the single freezing pipe with three analogy method are the same while the standard deviations are different. The distributions of standard deviation have a great difference at different radial coordinate location and the larger standard deviations are mainly at the phase change area. The computed data with random variable method and stochastic process method have a great difference from the measured data while the computed data with random field method well agree with the measured data. Each uncertain thermal parameter has a different effect on the standard deviation of frozen soil temperature around the single freezing pipe. These results can provide a theoretical basis for the design and construction of AGF.

The knowledge and skills about the basic life support (BLS) and the advanced life support are the most important determining factors of the cardiopulmonary resuscitation (CPR) success rates. To determine the level of awareness on BLS and skills among undergraduate and postgraduate students of medical and dental profession, as well as nursing students and interns in a tertiary care hospital. This descriptive cross-sectional study was conducted in a tertiary care hospital in South India. The awareness level on BLS and factors associated which include age, sex, level of training (undergraduate, internship, and postgraduate groups), course of study (nursing, dental, and medical groups), and previous exposure to BLS were assessed by using a structured questionnaire. The association of these variables with awareness level was assessed by independent t test, analysis of variance, and linear regression analysis. Among 520 study subjects, 229 were students, 171 were interns, and 120 were postgraduate students. The overall mean score of awareness was 4.16 ± 1.40 (score range: 0-10). Age, sex, level of training, course of study, and previous exposure to BLS were significantly associated with awareness level in univariate analysis (P < 0.05). Linear regression model also showed that all the above variables were significantly associated with awareness level (P < 0.05). About 322 (61.9%) subjects attributed lack of awareness about BLS to lack of available professional training. About 479 (92.1%) responded that BLS training should be a part of medical curriculum. Awareness level on BLS is below average indicating the importance of professional training at all levels in a tertiary care health institution.
