    This meeting was held on March 4, 1993. Since the first power generation with the JPDR and the initial criticality of the KUR, 30 years, and since the initial criticality of the KUCA, 20 years have elapsed. The researchers in universities have contributed greatly to the research and education of atomic energy, but the perspective of leading the world hereafter in this field is very uncertain. This study meeting was held to seek the way to make the proper contribution. In the meeting, lectures were given on Japanese policy on nuclear fuel cycle, the present state of the upstream research and the downstream research in Japan, the experimental plan in NUCEF, the present state of the researches on TRU decay heat data and TRU nucleus data, the present state of the experimental researches at KUCA and at FCA, the present state of the research on the heat removal from high conversion LWRs and the KUR, the present state of the research on radioactive waste treatment, and the present state of TRU chemical research.

    Jeremy Rifkin has filed a lawsuit to block U.S. Department of Agriculture (USDA) experiments involving the transfer of human growth hormone genes into sheep and pigs, which he rejects on environmental, economic, and ethical grounds. His real target is the Department's animal breeding program; his ultimate aim is "to establish the principle that there should be no crossing of species barriers in animals." USDA officials have not yet responded to the lawsuit but they intend to continue the experiments, which they consider crucial to the progress of research, until told to stop.

    2004-01-01

    The Advanced Photon Research Center (APRC) of Japan Atomic Energy Research Institute is pursing the research and development of advanced photon sources such as a compact, ultra-short, high intensity laser, x-ray laser, and a superconducting linac-based free electron laser (FEL) and their applications. These compact and high-intensity lasers have various capabilities of producing radiations with distinguishing characteristics of ultra-short pulse, high coherence, etc. Hence, they can provide novel means of research in the field of nuclear energy applications and industrial and medical technologies. It is important for us to promote these researches on these high-intensity laser applications comprehensively and effectively under the collaborations with nationwide universities and industry. From this point of view it is expected that the APRC plays a role as a COE for these researches. Through these research activities for development of high-intensity lasers and their applications, we will develop ''photon science and technology'' as a leading key technology in the 21st century and contribute the development of science and technology including nuclear energy technology and production of new industries.

    It is important to evaluate the stability of a repository for high-level radioactive waste not only during the design, construction and operation phases, but also during the post-closure period, for time frames likely exceeding several millennia or longer. The rock mass around the tunnels could be deformed through time in response to time dependent behavior such as creep and stress relaxation. Therefore, development of methodology to evaluate the past long-term behavior of rock mass is considered to be an issue. In view of above points, this study has been started as a collaboration study with the University of Tokyo from Fiscal Year 2016. In FY 2016, creep testing on Tage tuff was continuously conducted. Existing theory of rate process and stochastic process was modified to be applied to evaluate effects of water, and then the modified theory was validated based on the results of strength and creep tests performed under dry and wet conditions. Furthermore, effects of water contents on stress-strain curves were examined by uniaxial compression testing under various water content conditions. (author)

  7. Linking aims, paradigm and method in nursing research.

    To explore the use of paradigms as ontological and philosophical guides for conducting PhD research. A paradigm can help to bridge the aims of a study and the methods to achieve them. However, choosing a paradigm can be challenging for doctoral researchers: there can be ambiguity about which paradigm is suitable for a particular research question and there is a lack of guidance on how to shape the research process for a chosen paradigm. The authors discuss three paradigms used in PhD nursing research: post-positivism, interpretivism and pragmatism. They compare each paradigm in relation to its ontology, epistemology and methodology, and present three examples of PhD nursing research studies to illustrate how research can be conducted using these paradigms in the context of the research aims and methods. The commonalities and differences between the paradigms and their uses are highlighted. Creativity and flexibility are important when deciding on a paradigm. However, consistency and transparency are also needed to ensure the quality and rigour necessary for conducting nursing research. When choosing a suitable paradigm, the researcher should ensure that the ontology, epistemology and methodology of the paradigm are manifest in the methods and research strategies employed.

    In an attempt to deal with the pressures on the health-care system and to guarantee sustainability, changes are needed. This study focuses on a cardiology primary care plus intervention. Primary care plus (PC+) is a new health-care delivery model focused on substitution of specialist care in the hospital setting with specialist care in the primary care setting. The intervention consists of a cardiology PC+ centre in which cardiologists, supported by other health-care professionals, provide consultations in a primary care setting. The PC+ centre aims to improve the health of the population and quality of care as experienced by patients, and reduce the number of referrals to hospital-based outpatient specialist care in order to reduce health-care costs. These aims reflect the Triple Aim principle. Hence, the objectives of the study are to evaluate the cardiology PC+ centre in terms of the Triple Aim outcomes and to evaluate the process of the introduction of PC+. The study is a practice-based, quantitative study with a longitudinal observational design, and an additional qualitative study to supplement, interpret and improve the quantitative study. The study population of the quantitative part will consist of adult patients (≥18 years) with non-acute and low-complexity cardiology-related health complaints, who will be referred to the cardiology PC+ centre (intervention group) or hospital-based outpatient cardiology care (control group). All eligible patients will be asked to complete questionnaires at three different time points consisting of questions about their demographics, health status and experience of care. Additionally, quantitative data will be collected about health-care utilization and related health-care costs at the PC+ centre and the hospital. The qualitative part, consisting of semi-structured interviews, focus groups, and observations, is designed to evaluate the process as well as to amplify, clarify and explain quantitative results.

    2008-01-01

    This work presents a study of human factors and possible human failure reasons that can cause incidents, accidents and workers exposition, associated to risks intrinsic to the profession. The objective is to contribute with the operators of IEA-R1 reactor located at IPEN CNEN/S P. Accidents in the technological field, including the nuclear, have shown that the causes are much more connected to human failure than to system and equipment failures, what has led the regulatory bodies to consider studies on human failure. The research proposed in this work is quantitative/qualitative and also descriptive. Two questionnaires were used to collect data. The first of them was elaborated from the safety culture attributes which are described by the International Atomic Energy Agency - IAEA. The second considered individual and situational factors composing categories that could affect people in the work area. A carefully selected transcription of the theoretical basis according to the study of human factors was used. The methodology demonstrated a good reliability degree. Results lead to mediate factors which need direct actions concerning the needs of the group and of the individual. This research shows that it is necessary to have a really effective unit of planning and organization, not only to the physical and psychological health issues but also to the safety in the work.

    While a number of preventive interventions delivered within schools have shown both short-term and long-term impact in epidemiologically based randomized field trials, programs are not often sustained with high-quality implementation over time. This study was designed to support two purposes. The first purpose was to test the effectiveness of a universal classroom-based intervention, the Whole Day First Grade Program (WD), aimed at two early antecedents to drug abuse and other problem behaviors, namely, aggressive, disruptive behavior and poor academic achievement. The second purpose--the focus of this paper--was to examine the utility of a multilevel structure to support high levels of implementation during the effectiveness trial, to sustain WD practices across additional years, and to train additional teachers in WD practices. The WD intervention integrated three components, each previously tested separately: classroom behavior management; instruction, specifically reading; and family-classroom partnerships around behavior and learning. Teachers and students in 12 schools were randomly assigned to receive either the WD intervention or the standard first-grade program of the school system (SC). Three consecutive cohorts of first graders were randomized within schools to WD or SC classrooms and followed through the end of third grade to test the effectiveness of the WD intervention. Teacher practices were assessed over three years to examine the utility of the multilevel structure to support sustainability and scaling-up. The design employed in this trial appears to have considerable utility to provide data on WD effectiveness and to inform the field with regard to structures required to move evidence-based programs into practice.

    2007-05-01

    Full Text Available Abstract Background There has been considerable interest recently in developing and evaluating interventions to increase research use by clinicians. However, most work has focused on medical practices; and nursing is not well represented in existing systematic reviews. The purpose of this article is to report findings from a systematic review of interventions aimed at increasing research use in nursing. Objective To assess the evidence on interventions aimed at increasing research use in nursing. Methods A systematic review of research use in nursing was conducted using databases (Medline, CINAHL, Healthstar, ERIC, Cochrane Central Register of Controlled Trials, and Psychinfo, grey literature, ancestry searching (Cochrane Database of Systematic Reviews, key informants, and manual searching of journals. Randomized controlled trials and controlled before- and after-studies were included if they included nurses, if the intervention was explicitly aimed at increasing research use or evidence-based practice, and if there was an explicit outcome to research use. Methodological quality was assessed using pre-existing tools. Data on interventions and outcomes were extracted and categorized using a pre-established taxonomy. Results Over 8,000 titles were screened. Three randomized controlled trials and one controlled before- and after-study met the inclusion criteria. The methodological quality of included studies was generally low. Three investigators evaluated single interventions. The most common intervention was education. Investigators measured research use using a combination of surveys (three studies and compliance with guidelines (one study. Researcher-led educational meetings were ineffective in two studies. Educational meetings led by a local opinion leader (one study and the formation of multidisciplinary committees (one study were both effective at increasing research use. Conclusion Little is known about how to increase research use in

    Although opinions preferring individual administration of activity in the treatment of thyroid cancer with 131 I predominate, sufficient quantitative arguments in favor of this approach are unavailable as yet. Therefore, a retrospective study involving statistical processing was proposed with the aim to evaluate the relations between available data of the patients and success of treatment. Ideally, recommendations regarding activity to be administered in dependence on the biophysical status of the patient should emerge from the study

    Fostering collaborations across multiple disciplines within and across institutional boundaries is becoming increasingly important with the growing emphasis on translational research. As a result, Research Networking Systems that facilitate discovery of potential collaborators have received significant attention by institutions aiming to augment their research infrastructure. We have conducted a survey to assess the state of adoption of these new tools at the Clinical and Translational Science Award (CTSA) funded institutions. Survey results demonstrate that most CTSA funded institutions have either already adopted or were planning to adopt one of several available research networking systems. Moreover a good number of these institutions have exposed or plan to expose the data on research expertise using linked open data, an established approach to semantic web services. Preliminary exploration of these publically-available data shows promising utility in assessing cross-institutional collaborations. Further adoption of these technologies and analysis of the data are needed, however, before their impact on cross-institutional collaboration in research can be appreciated and measured.

    Full Text Available The research site “Vrchslatina” was established in the spring of 2009 with the aim of studying production processes and the structure of net primary productivity in young forest stands. The beech and spruce stands grown at the site were selected because they originated from natural regeneration and are nearly of the same age. In 2009, we established 5 research plots in each stand with the aim of measuring basic tree characteristics. Moreover, we excavated entire trees to construct allometric relations for the specific tree compartments. In the consecutive years (2010, 2011 and 2012, we also included grass communities dominated by Calamagrostis epigejos in our studies. Besides studying production processes of all tree compartments (i.e. for trees: foliages, branches, stem, coarse and fine roots, for grasses and herbs: below- and above-ground parts, we monitored several atmospheric characteristics, followed by soil characteristics and eventually added a measurement of soil respiration. The results indicated that forest stands (even though they were in their initial growth stages sequestrated much more carbon than the grass communities. Moreover, we proved the considerable influence of climatic conditions (especially the sum of precipitation in the particular years for net primary productivity.

    Over the past 30 years, the international conference on Artificial Intelligence in MEdicine (AIME) has been organized at different venues across Europe every 2 years, establishing a forum for scientific exchange and creating an active research community. The Artificial Intelligence in Medicine journal has published theme issues with extended versions of selected AIME papers since 1998. To review the history of AIME conferences, investigate its impact on the wider research field, and identify challenges for its future. We analyzed a total of 122 session titles to create a taxonomy of research themes and topics. We classified all 734 AIME conference papers published between 1985 and 2013 with this taxonomy. We also analyzed the citations to these conference papers and to 55 special issue papers. We identified 30 research topics across 12 themes. AIME was dominated by knowledge engineering research in its first decade, while machine learning and data mining prevailed thereafter. Together these two themes have contributed about 51% of all papers. There have been eight AIME papers that were cited at least 10 times per year since their publication. There has been a major shift from knowledge-based to data-driven methods while the interest for other research themes such as uncertainty management, image and signal processing, and natural language processing has been stable since the early 1990s. AIME papers relating to guidelines and protocols are among the most highly cited. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Background and origins of research of Adam Curtis. One persisting theme has been the pursuit of different landscapes at different scales to discover the routes to explain how the body is built. His research life fell in a fortunate period during which techniques and concepts for investigating structure have improved year by year. His most fortunate encounter was with Michael Abercrombie and his views on the social behaviour of cells, aims for quantitation, and statistical testing. Adam worked in various environments - in turn Geology as an undergraduate, Biophysics Ph.D. in a Genetics department and various departments in turn from anatomy via zoology to Cell Biology. Adam started his Ph.D. work in cell adhesion, studying cell movement, trapping and reaggregation phenomena, having an early start from the physico-chemical viewpoint. He made quantitative measurements of cell adhesion by kinetic methods. Interference reflection microscopy (IRM and related optical interference techniques were brought into the field of biology by him. In turn this led with Chris Wilkinson, a long term colleague, to the use of micro- and nanofabrication for biological research. Polscope and photoelastic measurements were introduced to biology recently in his laboratory. One long term theme has been to map the adhesion of cells to substrates to discover contact areas. Early data came from IRM and then TIRF (Total Internal Reflection Fluorescence Microscopy and then from Forster Resonance Energy Microscopy (FRET. Another important theme was the time scale that needed to be measured - very short indeed in suspension. This was very difficult and has only become possible very recently but hydrodynamic calculation shows it must be very short. The attractions of the Derjagin-Landau-Verwey-Overbeek theory (DLVO theory are that they explain many features of biological adhesion. The main test of this theory depends upon the energy of the adhesion at various different separation

    Medication administration is an important and essential nursing function with the potential for dangerous consequences if errors occur. Not only must nurses understand the use and outcomes of administering medications they must be able to calculate correct dosages. Medication administration and dosage calculation education occurs across the undergraduate program for student nurses. Research highlights inconsistencies in the approaches used by academics to enhance the student nurse's medication calculation abilities. The aim of this integrative review was to examine the literature available on effective education strategies for undergraduate student nurses on medication dosage calculations. A literature search of five health care databases: Sciencedirect, Cinahl, Pubmed, Proquest, Medline to identify journal articles between 1990 and 2012 was conducted. Research articles on medication calculation educational strategies were considered for inclusion in this review. The search yielded 266 papers of which 20 meet the inclusion criteria. A total of 5206 student nurse were included in the final review. The review revealed educational strategies fell into four types of strategies; traditional pedagogy, technology, psychomotor skills and blended learning. The results suggested student nurses showed some benefit from the different strategies; however more improvements could be made. More rigorous research into this area is needed.

    2016-04-01

    Vertigo is one of the most common complaints in medicine. Despite its high prevalence, patients with vertigo often receive either inappropriate or inadequate treatment. The most important reasons for this deplorable situation are insufficient interdisciplinary cooperation, nonexistent standards in diagnostics and therapy, the relatively rare translations of basic science findings to clinical applications, and the scarcity of prospective controlled multicenter clinical trials. To overcome these problems, the German Center for Vertigo and Balance Disorders (DSGZ) started an initiative to establish a European Network for Vertigo and Balance Research called DIZZYNET. The central aim is to create a platform for collaboration and exchange among scientists, physicians, technicians, and physiotherapists in the fields of basic and translational research, clinical management, clinical trials, rehabilitation, and epidemiology. The network will also promote public awareness and help establish educational standards in the field. The DIZZYNET has the following objectives as regards structure and content: to focus on multidisciplinary translational research in vertigo and balance disorders, to develop interdisciplinary longitudinal and transversal networks for patient care by standardizing and personalizing the management of patients, to increase methodological competence by implementing common standards of practice and quality management, to internationalize the infrastructure for prospective multicenter clinical trials, to increase recruitment capacity for clinical trials, to create a common data base for patients with vertigo and balance disorders, to offer and promote attractive educational and career paths in a network of cooperating institutions. In the long term, the DIZZYNET should serve as an internationally visible network for interdisciplinary and multiprofessional research on vertigo and balance disorders. It ideally should equally attract the afflicted patients and

    Full Text Available The increase in population as well as the water resource demand has been intensifying the human influence in Peri Lagoon basin. A review on the availability of data concerning the ecology of Peri Lagoon was made, aiming at the development of new researches to understand the functioning of this ecosystem. This information can contribute to the elaboration of a conservation proposal and sustainable use of the Lagoon in the future. High cyanobacteria density (Cylindrospermopsis raciborskii was detected in the Lagoon waters, which happens to be a risky situation for the ecosystem’s health and consequently for the population. The review highlights a lack of available information about the dynamics, functioning and structure of aquatic communities, as well as their relationships with the surrounding area and the infl uence of abiotic factors. Series of continuum data with respect to time are also considered to be lacking. Educational, political and social practices in environmental conservation are necessary, aiming at the management and sustainable use of Peri Lagoon basin. These practices will guarantee water resource quality and availability for the current and future generations.

    In workshops on GLOBE at Night, teacher professional development has begun on using night sky brightness data and bat telemetry data to do scientific research in the classroom. The study looks at the effects of light pollution on the flight paths of threatened and endangered (T&E) bats between their day roosts and night foraging areas. A jump-start in getting secondary school students involved was the BioBlitz event in Tucson, Arizona in October 2011. During the 24-hour event, night Sky Quality Meter (SQM) data was taken across the Saguaro National Park West, through Tucson and across the Saguaro National Park East. The program had its beginning with a pair of Research Experiences for Undergraduates (REU) students and their advisor. Through the collaboration of the National Science Foundation's REU program, the National Optical Astronomy Observatory's GLOBE at Night program and the U.S. Arizona Game and Fish Department (AzGFD), two REU students along with their advisor used data from the GLOBE at Night project and telemetry tracking data of lesser long-nosed bats to study the effects of light pollution on the flight paths of the bats between their day roosts and night foraging areas around the city of Tucson, AZ. During the summer of 2010, the first REU student used the visual limiting magnitude data from GLOBE at Night and, with the assistance of the AzGFD, ran compositional analyses with respect to the bats' flight paths to determine whether the bats were selecting for or against flight through regions of particular night sky brightness levels. The bats selected for the regions in which the limiting sky magnitudes fell between the ranges of 2.8-3.0 to 3.6-3.8 and 4.4-4.6 to 5.0-5.2, suggesting that the lesser long-nosed bat can tolerate a fair degree of urbanization. Three areas of systematic uncertainty were identified of which 2 could be addressed the following summer. Due to a relatively large uncertainty in each individually measured visual limiting magnitude

    We present a systematic empirical update and critical evaluation of the current status of research aimed at identifying a variety of psychological mediators in various forms of psychotherapy for depression. We summarize study characteristics and results of 35 relevant studies, and discuss the extent to which these studies meet several important requirements for mechanism research. Our review indicates that in spite of increased attention for the topic, advances in theoretical consensus about necessities for mechanism research, and sophistication of study designs, research in this field is still heterogeneous and unsatisfactory in methodological respect. Probably the biggest challenge in the field is demonstrating the causal relation between change in the mediator and change in depressive symptoms. The field would benefit from a further refinement of research methods to identify processes of therapeutic change. Recommendations for future research are discussed. However, even in the most optimal research designs, explaining psychotherapeutic change remains a challenge. Psychotherapy is a multi-dimensional phenomenon that might work through interplay of multiple mechanisms at several levels. As a result, it might be too complex to be explained in relatively simple causal models of psychological change. Copyright © 2016 Elsevier Ltd. All rights reserved.

    In response to NSF's plans to establish a network of hydrologic observatories, a planning group is proposing a Sierra Nevada Hydrologic Observatory (SNHO). As argued in multiple consensus planning documents, the semi-arid mountain West is perhaps the highest priority for new hydrologic understanding. Based on input from over 100 individuals, it is proposed to initiate a mountain-range-scale study of the snow-dominated hydrology of the region, focusing on representative 1,000-5,000 km2 river basins originating in the Sierra Nevada and tributary to the Sacramento-San-Joaquin Delta. The SNHO objective is to provide the necessary infrastructure for improved understanding of surface-water and ground-water systems, their interactions and their linkages with ecosystems, biogeochemistry, agriculture, urban areas and water resources in semi-arid regions. The SNHO will include east-west transects of hydrological observations across the Sierra Nevada and into the basin and range system, in four distinct latitude bands that span much of the variability found in the semi-arid West. At least one transect will include agricultural and urban landscapes of the Great Central Valley. Investments in measurement systems will address scales from the mountain range down to the basin, headwater catchment and study plot. The intent is to provide representative measurements that will yield general knowledge as opposed to site-specific problem solving of a unique system. The broader, general science question posed by the planning group is: How do mountain hydrologic processes vary across landscapes, spanning a range of latitudes, elevations and thus climate, soils, geology and vegetation zones?\\" Embodied are additional broad questions for the hydrologic science community as a whole: (i) How do hydrologic systems that are subjected to multiple perturbations respond? (ii) How do pulses and changes propagate through the hydrologic system? (iii) What are the time lags and delays of stresses in

  16. Fusion power: massive research program aims at formidable problems, almost limitless potential

    International Nuclear Information System (INIS)

    Dingee, D.A.

    1979-01-01

    This article surveys extensively fusion development under the following topics: US research directions; inertial confinement fusion; foreign fusion efforts; fusion issues; fusion applications; and arguments for fusion development. Dr. Dingee points out that, despite persuasive arguments for development, fusion has as yet attracted no substantial constituency; and that winning greater support for fusion may thus require a considerable technical breakthrough (namely, proof of scientific feasibility or achievement of energy breakeven) - or a new focus on an energy source such as hybrids, which offer a nearer-term payoff than pure fusion. Dr. Dingee says the next major facility for magnetic confinement research (to be built in late 1980s) has not yet been selected, but will probably be an engineering test facility; there are similar plans for inertial confinement. Whichever type is chosen, the first experimental power reactor is scheduled for the first few years of the 2000's, this to be followed by commercial demonstration of fusion power in the 2010 to 2020 time frame. He points out, finally, that the complex technical and institutional issues are being considered in a climate in which the benefits of nuclear energy itself are being questioned; and that there is little doubt that future development is tied to overall decisions the nation will make regarding the value of nuclear energy

    2005-01-01

    Safety culture has been defined as 'that assembly of characteristics and attitudes in organizations and individuals which establishes that as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance'. This paper briefly highlights efforts being made at the Centre for Energy Research and Training (CERT) towards realizing this broad objective as far as possible. To this end CERT realizes the need for instituted safety measures to reflect significant, site-specific peculiar characteristics of any generic reactor types. Consequently, standard procedures for pre-startup, startup and shutdown of NIRR-1 (a miniature neutron source reactor - MNSR) have been reviewed to reflect our local conditions and peculiarities. The review has revealed the need to incorporate important steps that impact on overall safety of the facility. For instance an interlocking system is being considered between NIRR-1 startup on the one hand and mandatory pre-startup measures on the other. Also a procedure has been put in place that would facilitate rapid response in the event of a rod-stuck-at-full-withdrawal incident. Furthermore, a program of automation of important analysis and design calculations of MNSRs is going on. Emphases are also placed, and deliberate efforts are being made, to ensure that a working atmosphere prevails that would foster the correct attitudinal approach to matters of reactor safety. A regime of constant dialogue and discussions amongst operating personnel has been factored into the overall operational program. (author)

    There is a growing emphasis on behavior change in intervention development programmes aimed at improving public health and healthcare professionals' practice. A number of frameworks and methodological tools have been established to assist researchers in developing interventions seeking to change healthcare professionals' behaviors. The key features of behavior change intervention design involve specifying the target group (i.e. healthcare professional or patient cohort), the target behavior and identifying mediators (i.e. barriers and facilitators) of behavior change. Once the target behavior is clearly specified and understood, specific behavior change techniques can then be used as the basis of the intervention to target identified mediators of behavior change. This commentary outlines the challenges for pharmacy practice-based researchers in targeting dispensing as a behavior when developing behavior change interventions aimed at pharmacists and proposes a definition of dispensing to consider in future research.

    The Education and Public Outreach (EPO) component of the satellite-based research mission "Aeronomy of Ice In the Mesosphere" (AIM) will bridge the unique scientific aspects of the mission to informal education organizations. The informal education materials developed by the EPO will utilize AIM data and educate the public about the environmental implications associated with the data. This will assist with creating a scientifically literate workforce and in developing a citizenry capable of making educated decisions related to environmental policies and laws. The objective of the AIM mission is to understand the mechanisms that cause Polar Mesospheric Clouds (PMCs) to form, how their presence affects the atmosphere, and how change in the atmosphere affects them. PMCs are sometimes known as Noctilucent Clouds (NLCs) because of their visibility during the night from appropriate locations. The phenomenon of PMCs is an observable indicator of global change, a concern to all citizens. Recent sightings of these clouds over populated regions have compelled AIM educators to expand informal education opportunities to communities worldwide. Collaborations with informal organizations include: Museums/Science Centers; NASA Sun-Earth Connection Forum; Alaska Native Ways of Knowing Project; Amateur Noctilucent Cloud Observers Organization; National Parks Education Programs; After School Science Clubs; Public Broadcasting Associations; and National Public Radio. The Native Ways of Knowing Project is an excellent example of informal collaboration with the AIM EPO. This Alaska based project will assist native peoples of the state with photographing NLCs for the EPO website. It will also aid the EPO with developing materials for informal organizations that incorporate traditional native knowledge and science, related to the sky. Another AIM collaboration that will offer citizens lasting informal education opportunities is the one established with the United States National Parks

    In paediatric palliative care (PPC), parents are confronted with increasing caregiving demands. More children are cared for at home, and the need for PPC of children is lengthened due to technical and medical improvements. Therefore, a clear understanding of the content of parental caregiving in PPC becomes increasingly important. The objective is to gain insight into parental caregiving based on the lived experience of parents with a child with a life-limiting disease. An interpretative qualitative study using thematic analysis was performed. Single or repeated interviews were undertaken with 42 parents of 24 children with a malignant or non-malignant disease, receiving PPC. Based on their ambition to be a 'good parent', parents caring for a child with a life-limiting disease strived for three aims: controlled symptoms and controlled disease, a life worth living for their ill child and family balance. These aims resulted in four tasks that parents performed: providing basic and complex care, organising good quality care and treatment, making sound decisions while managing risks and organising a good family life. Parents need early explanation from professionals about balancing between their aims and the related tasks to get a grip on their situation and to prevent becoming overburdened. What is Known: • In paediatric palliative care, parents are confronted with increasing caregiving demands. • Parenting is often approached from the perspective of stress. What is New: • Parents strive for three aims: controlled symptoms and controlled disease, a life worth living for their child and family balance. • Parents perform four tasks: providing basic and complex care, organising good quality care, making decisions while managing risks and organising a good family life. • Professionals need insight into the parents' aims and tasks from the parental perspective to strengthen parents' resilience.

  7. Computational study of formamide-water complexes using the SAPT and AIM methods

    2006-01-01

    In this work, the complexes formed between formamide and water were studied by means of the SAPT and AIM methods. Complexation leads to significant alterations in the geometries and electronic structure of formamide. Intermolecular interactions in the complexes are intense, especially in the cases where the solvent interacts with the carbonyl and amide groups simultaneously. In the transition states, the interaction between the water molecule and the lone pair on the amide nitrogen is also important. In all the complexes studied herein, the electrostatic interactions between formamide and water are the main attractive force, and their contribution may be five times as large as the corresponding contribution from dispersion, and twice as large as the contribution from induction. However, an increase in the resonance of planar formamide with the successive addition of water molecules may suggest that the hydrogen bonds taking place between formamide and water have some covalent character

    Purpose: Intensity modulated radiation therapy plans are designed to optimally target a tumor while sparing surrounding tissue. Desired dose distributions are iteratively approached via inverse planning. This leads to tradeoffs between clinical objectives for the planning target volume (PTV), organs at risk, and normal tissues. Dose volume histogram (DVHs) related aims are followed that are either institutional or internationally recommended. We analyze common goals and identify potential reasons that often lead to tradeoffs. Methods: 524 IMRT plans for various tumor sites were analyzed based on the main institutional DVH goal for PTV (D95) and the recommendations by ICRU-83 (D2, D50, and D98). Robust statistical tools are developed and applied to ensure that the results are immune to data uncertainties. The probability of violation was measured for each of the DVH goals based on the frequency of not meeting recommended doses. Conditional probabilities for satisfying and/or violating DVH aims were computed to test the hypothesized pair-wise relations between DVH aims. For example, for plans that satisfied D50, the probability of violating D98 was computed via P(D98 < 95% | 98% ≤ D50 ≤ 102%). The equality constraint D50 = 100% was relaxed to encompass the range [98,102]%. Results: A large majority of cases (88%) satisfied the institutional goal for PTV of D95 ≤ 95%. Similar consensus existed for D98. 51% of cases satisfied D2 ≥ 107%. However, only 18% of cases satisfied D50. The conditional probability showed correlations amongst the studied DVH goals. In fact, a negative correlation was revealed between D50 and D95 (and D98), suggesting that these competing goals cannot be satisfied concurrently. Conclusion: The majority of plans followed the institutional guidelines. The reason for their deviation from international recommendations seems to be that the latter goals are competing and cannot be satisfied concurrently in clinical practice.

    In this paper we report on cathodoluminescence (CL) spectra of SnO{sub 2} powders, synthesized using the wet chemical route. The analysis of influence of the modes of calcination (T {sub an}-450-800 deg. C), and doping by both Pd and Pt (0.01-10.0 wt.%) on CL spectra was made. It was found that the measurement of CL spectra could be an effective research method of nanostructured metal oxides, aimed for gas sensor applications. It was established that in nanocrystalline SnO{sub 2} the same system of energy levels, associated with radiative recombination, as in single crystalline and polycrystalline SnO{sub 2}, is retained. It was found that doping by both Pd and Pt modifies the structural properties of SnO{sub 2} grains. Also, there is an optimum doping; near 0.1-0.2 wt.%, at which a maximum intensity of cathodoluminescence is reached. It was concluded that for low concentrations of both Pd and Pt additives in SnO{sub 2} an improvement of the material's crystal structure is promoted, and is associated with a decrease in the non-radiating recombination rate.

    Nursing students' independent projects in Sweden not only provide an opportunity to receive a professional qualification as a nurse but also gain a Bachelor's degree in nursing. The aim of these projects is to demonstrate knowledge and understanding within the major field of the education. This study aimed to describe and analyze the topics as well as theoretical frameworks and concepts in nursing students' independent projects, which lead to a Bachelor's degree, in a Swedish context. A total of 491 independent projects, written by nursing students in Sweden, were included in the study. Topics together with theoretical frameworks and concepts in the projects were identified. Similar topics and theoretical frameworks and concepts, respectively, were grouped into subcategories, and similar subcategories were then merged into a main category. The number of entries in each category was counted for descriptive statistics in order to allow for the demonstration of magnitude. The most common topics concerned experiences and managing when having an illness, experiences of care and of being a caregiver, and healthcare staff's care and knowledge. The nursing theories/models that were most often used were Eriksson's Theory of Caritative Caring, Travelbee's Human-to-Human Relationship Model, and Orem's Self-care Theory. Among the non-nursing theories/models, perspectives and concepts lifeworld, ethical values and principles, existential concepts and quality of life/health-related quality of life, were most often used by these students. There may be some difficulty in finding a topic for the project that is relevant for both a professional qualification as a nurse, as well as for achieving the requirements of a Bachelor's degree in nursing. The study indicates that there is a need to widen the student's understanding of different nursing theories/perspectives/models/concepts during nursing education so that students are familiar with a broad range of these when conducting their

    To describe the methodology of the EPISER 2016 (study of the prevalence of rheumatic diseases in adult population in Spain), as well its strengths and limitations. The aim of this study is to estimate the prevalence of rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), osteoarthritis (knee, hip, hands, and cervical and lumbar spine), fibromyalgia, gout and clinical osteoporotic fracture. Population-based, multicenter, cross-sectional study, with the participation of 45 municipalities in the 17 Spanish autonomous communities. The reference population will consist of adults aged 20 years and over residing in Spain. A computer-assisted telephone interview (CATI) system will be used for data collection. Diagnostic suspicions and diagnoses received by the participants will be studied by rheumatologists in the referral hospitals in the selected municipalities. the prevalence of the rheumatic diseases will be calculated using estimators and their 95% confidence intervals. Weights will be calculated in each of the sampling stages in accordance with the probability of selection. The distribution of the population in Spain will be obtained from the Spanish Statistics Institute. Sociodemographic and lifestyle changes over the last 16 years justify EPISER 2016. This study will provide current data about the prevalences of RA, AS, PsA, SLE, SS, osteoarthritis, fibromyalgia, gout and clinical osteoporotic fracture. The results will allow comparisons with studies from other countries and EPISER 2000.

    Full Text Available The objective of this paper is to identify and discuss trends in tools and methods used in project risk management and its relationship to other matters, using current scientific articles. The focus isn´t in understanding how they work in technical terms, but think about the possibilities of deepening in academic studies, including making several suggestions for future research. Adjacent to the article there is a discussion about an alleged "one best way" imperative normativity approach. It was answered the following research questions: what subjects and theories are related to project risk management tools and methods? The first contribution is related to the importance of the academic Chris Chapman as an author who has more published and also more referenced in the survey. There are several contributions on various subjects such as: the perception of the existence of many conceptual papers; papers about construction industry, problematization of contracts according to agency theory, IT and ERPs issues. Other contributions came from the bibliometric method that brings lot of consolidated information about terms, topics, authors, references, periods and, of course, methods and tools about Project Risk Management.

    The aims of this exploratory study were to explore dental faculty members' views and beliefs regarding knowledge, the dental profession, and teaching and learning and to determine how these views related to their problem-based learning (PBL) instructional practices. Prior to a PBL in dental education conference held in 2011, all attendees were invited to complete a survey focused on their pedagogical beliefs and practices in PBL. Out of a possible 55 participants, 28 responded. Additionally, during the conference, a forum was held in which preliminary survey findings were shared and participants contributed to focus group data collection. The forum results served to validate and bring deeper understanding to the survey findings. The conference participants who joined the forum (N=32) likely included some or many of the anonymous respondents to the survey, along with additional participants interested in dental educators' beliefs. The findings of the survey and follow-up forum indicated a disconnect between dental educators' reported views of knowledge and their pedagogical practices in a PBL environment. The results suggested that the degree of participants' tolerance of uncertainty in knowledge and the discrepancy between their epistemological and ontological beliefs about PBL pedagogy influenced their pedagogical choices. These findings support the idea that learner-centered, inquiry-based pedagogical approaches such as PBL may create dissonance between beliefs about knowledge and pedagogical practice that require the building of a shared understanding of and commitment to curricular goals prior to implementation to ensure success. The methods used in this study can be useful tools for faculty development in PBL programs in dental education.

    2009-01-01

    The problem of radioactive wastes is a concern of world-wide scope, a time that does not still have a defined local for the construction of a repository for radioactive wastes of high level. One of the preliminary stages for the choice of the place more appropriate is the geologic study associated to the experimental studies of adsorption of the involved chemical species in the process. In this work, a sample of basaltic rock was used, of the South Region of the Formation Serra Geral, collected in Frederico Westphalen Town (RS), that it will be probably a candidate to the rock hostess for location of radioactive wastes. Two experiments have been carried out through, namely: 'Test Batch' and Percolating, both under atmospheric pressure, at the ambient temperature of 25 deg C, with the purpose to study the capacity of sorption of the rare earth elements - REE. The REE are used in this work in function of its analogy with the actinides, aiming at to investigate the chemistry behavior and the speciation of the same in natural waters, searching the possibility of geologic storage of radioactive wastes, a time that the adsorption of the REE depends on variables of the environment as pH, ionic strength, temperature and presence of ligands, as carbonates and constituent of surfaces of minerals. Experiment of percolating of the REE was carried through, 100ppb, in the basalt (with 80 mesh) in solutions with ionic strength 1= 0,025 M and 1=0,5 M of NaCl. pH was controlled in a range of 5,6 the 7,6 with HNO 3 addition. The concentrations were analyzed by ICP-MS. The 'Batch Test' is an efficient form of studying sorption/desorption isotherms, beyond values of the reason between the distributions solid/solution and estimation of the solubility. The percolating experiment, was carried through under pH controlled around 6, and allowed to verify the behaviour of heavy REE in comparison with the light REE. (author)

    Okubo, Seisuke

    2005-02-01

    This study was started on the basis of the outcomes of the research project conducted between 1994 and 2003. In the fiscal year of 1994 when this project was started, a pneumatic creep testing machine was modified. At the end of the fiscal year of 1994, Inada granite was purchased, and the preliminary tests such as P-wave velocity measurement and Schmidt hammer testing were carried out. Through the fiscal year of 1995, a specimen of Tage tuff under water-saturated condition had been loaded in uniaxial condition in the pneumatic creep testing machine. In the fiscal year of 1995, the uniaxial compression and tension tests, and the short-term creep test of Inada granite were also carried out in the servo-controlled testing machines to obtain the complete stress-strain curves. A hydraulic creep testing machine which was planned to use in the next year was modified for long-term creep testing. Finally, a constitutive equation of variable compliance type was examined based on the experimental results. In the fiscal year of 1996, creep, compression and tension tests were carried out. Two types of pressure maintenance equipment (hydraulic and pneumatic types) were developed and examined. In the fiscal year of 1997, creep, compression and tension tests etc. were again carried out on the basis of the results heretofore. The experimental results of long-term creep testing of Tage tuff, middle-term creep testing of Inada granite were described. In both creep tests, samples were submerged in water. In the fiscal year of 1998, creep testing of Tage tuff was conducted. Results of relatively short-term (middle-term) creep conducted on a servo-controlled testing machine were also described. Sample rock was Sirahama sandstone that showed a considerably large creep strain in low stress level such as 17 % of the uniaxial compression strength. Results of triaxial compression test and uniaxial tension test including unloading-reloading tests were described. In the fiscal years of 1999

    Full Text Available The aim of this paper is characterize printed circuit board of computers and propose a hydrometallurgical route for silver recovery present in its composition. Initially, the printed circuit board was comminuted in both knife and hammer mills. The comminuted material was characterized by sieve analysis, chemical analysis by inductively coupled plasma optical emission spectrometry (ICP-OES and loss on ignition. Leaching tests were conducted in sulfuric acid, sulfuric acid in an oxidizing medium and nitric acid. The results indicated that the printed circuit board is mainly composed of copper (19.42%. Silver content of 0.045% was found. The route for silver recovery was leaching in sulfuric acid at 75°C for 18 hours. Then, leaching in sulfuric acid at 75°C in an oxidizing medium for 6 hours and nitric acid leaching at room temperature for 2 hours. Through of this route, 96.6% of silver was recovered.

    Full Text Available Abstract Background There is an overwhelming burden of cardiovascular disease, type 2 diabetes and chronic kidney disease among Indigenous Australians. In this high risk population, it is vital that we are able to measure accurately kidney function. Glomerular filtration rate is the best overall marker of kidney function. However, differences in body build and body composition between Indigenous and non-Indigenous Australians suggest that creatinine-based estimates of glomerular filtration rate derived for European populations may not be appropriate for Indigenous Australians. The burden of kidney disease is borne disproportionately by Indigenous Australians in central and northern Australia, and there is significant heterogeneity in body build and composition within and amongst these groups. This heterogeneity might differentially affect the accuracy of estimation of glomerular filtration rate between different Indigenous groups. By assessing kidney function in Indigenous Australians from Northern Queensland, Northern Territory and Western Australia, we aim to determine a validated and practical measure of glomerular filtration rate suitable for use in all Indigenous Australians. Methods/Design A cross-sectional study of Indigenous Australian adults (target n = 600, 50% male across 4 sites: Top End, Northern Territory; Central Australia; Far North Queensland and Western Australia. The reference measure of glomerular filtration rate was the plasma disappearance rate of iohexol over 4 hours. We will compare the accuracy of the following glomerular filtration rate measures with the reference measure: Modification of Diet in Renal Disease 4-variable formula, Chronic Kidney Disease Epidemiology Collaboration equation, Cockcroft-Gault formula and cystatin C- derived estimates. Detailed assessment of body build and composition was performed using anthropometric measurements, skinfold thicknesses, bioelectrical impedance and a sub-study used dual

  1. Exploring Study Designs for Evaluation of Interventions Aimed to Reduce Occupational Diseases and Injuries

    Full Text Available Effective interventions to reduce work-related exposures are available for many types of work-related diseases or injuries. However, knowledge of the impact of these interventions on injury or disease outcomes is scarce due to practical and methodological reasons. Study designs are considered for the evaluation of occupational health interventions on occupational disease or injury. Latency and frequency of occurrence of the health outcomes are two important features when designing an evaluation study with occupational disease or occupational injury as an outcome measure. Controlled evaluation studies—giving strong indications for an intervention effect—seem more suitable for more frequently occurring injuries or diseases. Uncontrolled evaluation time or case series studies are an option for evaluating less frequently occurring injuries or diseases. Interrupted time series offer alternatives to experimental randomized controlled trials to give an insight into the effectiveness of preventive actions in the work setting to decision and policy makers.

    Under present French practice, assessing the effects of radioactive discharges due to the various likely accident situations comes under 'L'Analyse de Surete Nucleaire' (Nuclear Safety Analysis). The assessment of radioactive discharges relating to normal working comes within the framework of radioecologic studies. Radioecology studies are undertkaen for every power station project. They consist in: - studying what is to be done with radioelements discharged as liquids or gases, - estimating their impact on the populations in the areas of influence of the power station and checking that this impact is permissible, - establishing a surveillance measuring programme for checking against the predictions made and, if required, determining the modifications to be made to the facilities or to their method of operation [fr

    2010-01-01

    Following the shortage in radioisotope availability the Technische Unversitaet Muenchen and the Belgian Institut National des Radioelements conducted a common study on the suitability of the FRM II reactor for the generation of Mo-99 as a fission product. A suitable irradiation channel was determined and neutronic calculations resulted in sufficiently high neutron flux densities to make FRM II a promising candidate for Mo-99 production. In addition the feasibility study provides thermohydraulic calculations as input for the design and integration of the additional cooling circuit into the existing heat removal systems of FRM II. The required in-house processes for a regular uranium target irradiation programme have been defined and necessary upgrades identified. Finally the required investment cost was estimated and a possible time schedule was given. (author)

    A thermohydraulic study of MTR fuel element is presented as a basic requirement for the development of an irradiation facility for testing fuel elements. A computer code named 'Thermo' has been developed for this purpose, which can stimulate different working conditions, such as, cooling, power elements and neutron flux, performing all pertinent thermohydraulic calculations. Thermocouples were used to measure the temperature gradients of the cooling fluid throughout the IEAR-1 reactor core. All experimental data are in good agreement with the theoretical model applied in this work. Finally, a draft of the proposed facility and its safety system is presented. (author)

    To examine transient environmental exposures and their relationship with human fecundity, exposure assessment should occur optimally at the time of conception in both members of the couple. We performed an observational, prospective cohort study with biomonitoring in both members of a heterosexual couple trying to conceive. Couples collected urine, saliva, and semen specimens for up to two menstrual cycles on days corresponding to the time windows of fertilization, implantation, and early pregnancy, identified based on the woman's observations of her cervical fluid. Three hundred nine eligible couples were screened between 2011 and 2015, of which 183 enrolled. Eleven couples (6.0 %) withdrew or were lost to follow up. The most successful and cost effective recruiting strategies were word of mouth (40 % of participating couples), posters and flyers (37 %), and targeted Facebook advertising (13 %) with an overall investment of $37.35 spent on recruitment per couple. Both men and women collected ≥97.2 % of requested saliva samples, and men collected ≥89.9 % of requested semen samples. Within the periovulatory days (±3 days), there was at least one urine specimen collected by women in 97.1 % of cycles, and at least one by men in 91.7 % of cycles. Daily compliance with periovulatory urine specimens ranged from 66.5 to 92.4 % for women and from 55.7 to 75.0 % for men. Compliance was ≥88 % for questionnaire completion at specified time points. Couples planning to conceive can be recruited successfully for periconceptional monitoring, and will comply with intensive study protocols involving home collection of biospecimens and questionnaire data.

    This work addresses the characterization of physical, chemical and mechanical properties of steel slag as an alternative aggregation before and after leaching testing controlled Soxhlet extractor. The material it was characterized before going through the natural leaching process and after controlled leaching in different periods of 24, 56, 96, 120 hours. The steel slag was subjected in the laboratory to simulate the precipitation in Soxhlet equipment to evaluate its physical, chemical and mechanical properties after each period described. The study of the process of leaching in steel slag searched to understand the influence of the washing process in a slag behavior in such a process. The physical characterization occurred through traditional testing of coarse aggregates, the chemical characterization through the testing of Scanning Electron Microscopy (SEM) completed by Dispersive Spectroscopy Energy (DSE) and X- ray diffraction and the mechanical characterization through testing of standardized expansion and adapted. The sample virgin, without receiving process of stabilization by controlled leaching, showed satisfactory results in the physics characterization when compared to conventional aggregates, the chemical characterization proved to be a steel slag with high contents of CaO, MgO and FeO, the mechanical characterization demonstrated that, although the degree of expansibility of the slag is low demonstrated that this should not be disregarded in the paving work. After controlled leaching the steel slag showed no significant loss of its physical properties. As the mechanical testing of expansion had decreased the potential of expansibility after leaching periods. It is concluded that the leaching process in a Soxhlet extractor is of importance in the study the properties of steel slag, once covering several days of leaching was reduced potential for expansion, limiting feature in the use of steel slag for paving.

    2010-01-01

    The hydrogen, utilized in fuel cells, can be produced from a variety of intermediate chemicals, between them, the ammonia. The ammonia gas as a raw material for the hydrogen production has been used due to its high energetic content, facility of decomposition, high availability, low prices, low storage pressure and its by-products are environmentally correct. One of the sources of ammonia is poultry and egg production systems. In these systems the ammonia is produced from the decomposition of uric acid present in the excreta of birds. The residue from the poultry-rearing farms is the broiler litter and from the egg production system is the excreta without any substrate. The characterization of these residues was performed using the Wavelength-Dispersive X-Ray Fluorescence (WDXRF), Elementary Analysis (CHN), Thermogravimetry and GC/MS - Gas chromatography/ Mass spectrometry. The studied factors which influence the ammonia volatilization were: nitrogen content, raising period, urease enzyme, temperature, pH and moisture content. The experiment results with poultry litter and excreta allow to conclude that the manipulation of the following parameters increased the ammonia emission: pH, nitrogen content, raising period, age of birds and excreta accumulation, urease enzyme and the temperature. The addition of different amounts of sand in the excreta and different volumes of water in the poultry litter inhibited the emission of ammonia. The variation of the quantity of material (broiler litter or excreta) and the volume of the flask used as incubator chamber showed no significant alterations to be chosen as a variable. The excreta was considered more appropriate than poultry litter for the objectives of this work due to the higher ammonia concentrations determined in this material. Due to the large amount of poultry litter and excreta from the production processes, the reuse of poultry residues to obtain ammonia is necessary to improve the quality of the local

    Full Text Available Conversational analysis—situated between pragmatic linguistics and qualitative empirical research—is a complex method, which needs a lot of time and dedication. It is necessary to develop a so-called “analytical mentality”. The aim of the project presented in this paper was to develop the theoretical insights and the practical skills of a group of students for this kind of research. They worked together throughout the duration of the project, especially in the collec¬tion of empiric material: i.e. the recording of conversations between foreign and German stu¬dents, the transcription of the material, a group discussion on the data and finally its analysis. This articles aims at showing what students can learn by doing this kind of work, based on examples of the collected empirical material: (1 they will be introduced to the different levels and stages of the research process and have the chance to develop a methodical and methodological competence; (2 their general communicative competences and their special competences of the foreign language will increase, as well as (3 their knowledge of intercultural learning by working with authentic data of intercultural communication. So, for instance, stereotypes and how they have been constructed during the interaction may be analysed and precisely described on a micro-analytical level. URN: urn:nbn:de:0114-fqs0901335

    Full Text Available Based on awareness of material by Gramsci (1978, 1982 on hegemony, Freire (1979a, 1979b on cooperative contact, and Steiner (1975 on radical psychiatry, action research methodology was used by the researcher, who was also a psychotherapist, with 12 women attending two ongoing weekly psychotherapy groups in Brazil in order to raise their social consciousness of culturally-based oppression of women, particularly relating to work; to apply life script analysis as a therapeutic intervention within the groups; and to facilitate recognition by the women of the benefits of cooperative contact when seeking to liberate themselves from oppression.  Individual structured interviews were conducted and the data from these was discussed within the groups, leading to the development of a model containing 6 levels of consciousness of oppression.  Examples of oppression identified by the women are provided, with only 17% relating directly to sexual discrim-ination at work.  Although the research was conducted many years ago (1987-1989, it is shown that problems still exist and the research method-ology could usefully be applied elsewhere.

    Full Text Available In clinical trials the selection of appropriate outcomes is crucial to the assessment of whether one intervention is better than another. Selection of inappropriate outcomes can compromise the utility of a trial. However, the process of selecting the most suitable outcomes to include can be complex. Our aim was to systematically review studies that address the process of selecting outcomes or outcome domains to measure in clinical trials in children.We searched Cochrane databases (no date restrictions in December 2006; and MEDLINE (1950 to 2006, CINAHL (1982 to 2006, and SCOPUS (1966 to 2006 in January 2007 for studies of the selection of outcomes for use in clinical trials in children. We also asked a group of experts in paediatric clinical research to refer us to any other relevant studies. From these articles we extracted data on the clinical condition of interest, description of the method used to select outcomes, the people involved in the selection process, the outcomes selected, and limitations of the method as defined by the authors. The literature search identified 8,889 potentially relevant abstracts. Of these, 70 were retrieved, and 25 were included in the review. These studies described the work of 13 collaborations representing various paediatric specialties including critical care, gastroenterology, haematology, psychiatry, neurology, respiratory paediatrics, rheumatology, neonatal medicine, and dentistry. Two groups utilised the Delphi technique, one used the nominal group technique, and one used both methods to reach a consensus about which outcomes should be measured in clinical trials. Other groups used semistructured discussion, and one group used a questionnaire-based survey. The collaborations involved clinical experts, research experts, and industry representatives. Three groups involved parents of children affected by the particular condition.Very few studies address the appropriate choice of outcomes for clinical research

    The "Jackson Nursery", existing from February 1937 until March 1938, was directed by Anna Freud and financed by Edith Jackson and Dorothy Burlingham. It took care of infants from the poorest strata of Vienna and also gave material support to their families. On the other hand, it was a training institution for psychoanalysts, offering the opportunity of observing children during their first two years, e. g. their feeding habits and social sense. In addition, the Jackson Nursery was a place for research where psychoanalytic theories of infantile development were checked against the findings of direct observation. The work started here was then continued by A. Freud and D. Burlingham on a larger scale in their War Nurseries.--This paper examines the many-sided activities in the nursery mainly on the basis of unpu blished archival documents.

    Test results of the Aerothermodynamic Integration Model are presented. A program was initiated to develop a hydrogen-fueled research-oriented scramjet for operation between Mach 3 and 8. The primary objectives were to investigate the internal aerothermodynamic characteristics of the engine, to provide realistic design parameters for future hypersonic engine development as well as to evaluate the ground test facility and testing techniques. The engine was tested at the NASA hypersonic tunnel facility with synthetic air at Mach 5, 6, and 7. The hydrogen fuel was heated up to 1500 R prior to injection to simulate a regeneratively cooled system. The engine and component performance at Mach 6 is reported. Inlet performance compared very well both with theory and with subscale model tests. Combustor efficiencies up to 95 percent were attained at an equivalence ratio of unity. Nozzle performance was lower than expected. The overall engine performance was computed using two different methods. The performance was also compared with test data from other sources.

    Nearly all explosive ordnance disposal robots in use today employ monoscopic standard-definition video cameras to relay live imagery from the robot to the operator. With this approach, operators must rely on shadows and other monoscopic depth cues in order to judge distances and object depths. Alternatively, they can contact an object with the robot's manipulator to determine its position, but that approach carries with it the risk of detonation from unintentionally disturbing the target or nearby objects. We recently completed a study in which high-definition (HD) and stereoscopic video cameras were used in addition to conventional standard-definition (SD) cameras in order to determine if higher resolutions and/or stereoscopic depth cues improve operators' overall performance of various unmanned ground vehicle (UGV) tasks. We also studied the effect that the different vision modes had on operator comfort. A total of six different head-aimed vision modes were used including normal-separation HD stereo, SD stereo, "micro" (reduced separation) SD stereo, HD mono, and SD mono (two types). In general, the study results support the expectation that higher resolution and stereoscopic vision aid UGV teleoperation, but the degree of improvement was found to depend on the specific task being performed; certain tasks derived notably more benefit from improved depth perception than others. This effort was sponsored by the Joint Ground Robotics Enterprise under Robotics Technology Consortium Agreement #69-200902 T01. Technical management was provided by the U.S. Air Force Research Laboratory's Robotics Research and Development Group at Tyndall AFB, Florida.

  17. Considerations on aims and approaches of the study on the transport of trace elements in a river watershed

    2002-10-01

    Concerning the study subject on the transport of trace, toxic chemicals and radioactive elements in a river watershed, that has been developed in the Research Group for Terrestrial Environment, its aims and methodological approaches have been discussed in the light of related social and technological aspects of today. It is stressed that a study of the transport of radionuclides originated from a nuclear installation is needed to assess the physiological impact and to provide appropriate countermeasures in case of an accident. A numerical model is prerequisite for these objectives and to be keenly developed. The outcome of the modeling will be also important for a quantitative analysis of cycling of trace toxic elements in the atmosphere- lithosphere-hydrosphere, and also of the mechanisms of contamination of the surface aquatic environment. Accordingly, the study will contribute to the key issues stated in the national programs of science and technologies such as conservation of the natural and living environment. The present large consumption of metals and metalloids may cause an extensive contamination in the future. The study can provide solutions to the problems associated with metals and metalloids, because their environmental behavior resembles to that of radionuclides. From a methodological aspect, an importance of a direct investigation of physicochemical forms of trace, toxic elements must be stressed. A simultaneous use of experimental methods and chemical modeling to study the physico-chemical forms will be a good exemption to be realized hereafter. Experimentally, partitioning between solid and liquid phases using radioisotopes, and identification of solid species using various X-ray spectrometric techniques, for example, have been recognized very promising to investigate physico-chemical form of trace elements. These techniques are much ought to the nuclear sciences, suggesting further possible contribution of the nuclear sciences to the questions of

    Full Text Available Background: The current standard recommendation is to avoid surgical interventions in patients taking oral isotretinoin. However, this recommendation has been questioned in several recent publications. Aim: To document the safety of cosmetic and surgical interventions, among patients receiving or recently received oral isotretinoin. Materials and Methods: Association of Cutaneous Surgeons, India, in May 2012, initiated this study, at 11 centers in different parts of India. The data of 183 cases were collected monthly, from June 2012 to May 2013. Of these 61 patients had stopped oral isotretinoin before surgery and 122 were concomitantly taking oral isotretinoin during the study period. In these 183 patients, a total of 504 interventions were performed. These included[1] 246 sessions of chemical peels such as glycolic acid, salicylic acid, trichloroacetic acid, and combination peels;[2] 158 sessions of lasers such as ablative fractional laser resurfacing with erbium-doped yttrium aluminum garnet and CO2, conventional full face CO2laser resurfacing, laser-assisted hair reduction with long-pulsed neodymium-doped yttrium aluminum garnet, diode laser, and LASIK surgery;[3] 27 sessions of cold steel surgeries such as microneedling, skin biopsy, subcision, punch elevation of scars, excision of skin lesion, and wisdom tooth extraction;[4] 1 session of electrosurgery. Results: No significant side effects were noted in most patients. 2 cases of keloid were documented which amounted to 0.4% of side effects in 504 interventions, with a significant P value of 0.000. Reversible transient side effects were erythema in 10 interventions and hyperpigmentation in 15. Conclusion: The study showed that performing dermatosurgical and laser procedures in patients receiving or recently received isotretinoin is safe, and the current guidelines of avoiding dermatosurgical and laser interventions in such patients taking isotretinoin need to be revised.

    The function of the hypothalamo-pituitary-adrenal axis (HPA) has been widely investigated in mood disorders based on its role in regulating stress response. Particularly, Magnetic Resonance Imaging (MRI) reports have explored pituitary gland (PG) in both bipolar disorder (BD) and major depressive disorder (MDD). In this context, the present review summarizes the results from MRI studies with the final aim of commenting on the presence of common or distinct PG structural alterations between these two disabling illnesses. A bibliographic search on PUBMED of all MRI studies exploring PG volumes in BD and MDD as well as first-degree relatives (RELs) from 2000 up to October 2016 was performed. Following the screening process of the available literature it can be said that a) PG enlargement has been found in both BD and MDD, therefore potentially representing a common neurobiological marker characterizing mood disorders, and b) PG volumes are moderated by age and sex in both illnesses, although the direction and the extent of this moderation are still not fully clear. Few MRI studies with heterogeneous results. These hypotheses must be taken with caution especially because the heterogeneity of the results of the studies reviewed does not allow for a definite answer about the role of PG in affective disorders. Therefore, larger longitudinal studies investigating PG volumes in BD and MDD patients at the early phases of the illness, by considering females and males separately, are needed to further corroborate these findings.

    Health system planners aim to pursue the three goals of Triple Aim: 1) reduce health care costs; 2) improve population health; and 3) improve the care experience. Moreover, they also need measures that can reliably predict future health care needs in order to manage effectively the health system performance. Yet few measures exist to assess Triple Aim and predict future needs at a health system level. The purpose of this study is to explore the novel application of a case-mix adjustment method in order to measure and help improve the Triple Aim of health system performance. We applied a case-mix adjustment method to a population-based analysis to assess its usefulness as a measure of health system performance and Triple Aim. The study design was a retrospective, cohort study of adults from Ontario, Canada using administrative databases: individuals were assigned a predicted illness burden score using a case-mix adjustment system from diagnoses and health utilization data in 2008, and then followed forward to assess the actual health care utilization and costs in the following year (2009). We applied the Johns Hopkins Adjusted Clinical Group (ACG) Case-Mix System to categorize individuals into 60 levels of healthcare need, called ACGs. The outcomes were: 1) Number of individuals per ACG; 2) Total system costs per ACG; and 3) Mean cost per person per ACG, which together formed a health system "dashboard". We identified 11.4 million adults. 16.1% were aged 65 or older, 3.2 million (28%) did not use health care services that year, and 45,000 (0.4%) were in the highest acuity ACG category using 12 times more than an average adult. The sickest 1%, 5% and 15% of the population use about 10%, 30% and 50% of total health system costs respectively. The dashboard measures 2 dimensions of Triple Aim: 1) reduced costs: when total system costs per ACG or when average costs per person is reduced; and 2) improved population health: when more people move into healthier rather than

    Spiritual care is integral to quality palliative care. Although chaplains are uniquely trained to provide spiritual care, studies evaluating chaplains' work in palliative care are scarce. The goals of this pre-post study, conducted among patients with advanced cancer receiving outpatient palliative care, were to evaluate the feasibility and acceptability of chaplain-delivered spiritual care, utilizing the Spiritual Assessment and Intervention Model ("Spiritual AIM"), and to gather pilot data on Spiritual AIM's effects on spiritual well-being, religious and cancer-specific coping, and physical and psychological symptoms. Patients with advanced cancer (N = 31) who were receiving outpatient palliative care were assigned based on chaplains' and patients' outpatient schedules, to one of three professional chaplains for three individual Spiritual AIM sessions, conducted over the course of approximately six to eight weeks. Patients completed the following measures at baseline and post-intervention: Edmonton Symptom Assessment Scale, Steinhauser Spirituality, Brief RCOPE, Functional Assessment of Chronic Illness Therapy-Spiritual (FACIT-Sp-12), Mini-Mental Adjustment to Cancer (Mini-MAC), Patient Dignity Inventory, Center for Epidemiological Studies-Depression (10 items), and Spielberger State Anxiety Inventory. From baseline to post-Spiritual AIM, significant increases were found on the FACIT-Sp-12 Faith subscale, the Mini-MAC Fighting Spirit subscale, and Mini-MAC Adaptive Coping factor. Two trends were observed, i.e., an increase in Positive religious coping on the Brief RCOPE and an increase in Fatalism (a subscale of the Mini-MAC). Spiritual AIM, a brief chaplain-led intervention, holds potential to address spiritual needs and religious and general coping in patients with serious illnesses.

    Full Text Available Multiple-goal pursuit and conflict between personal life-defining goals can be considered part of everyday business in most individuals' lives. Given the potentially detrimental effects of goal conflict—for example, impaired well-being or poor performance—the literature on goal conflict is surprisingly scattered due to heterogeneous methodological approaches and technical terms. Little empirical research has addressed the conceptualization of goal conflict against the background of differing understandings from a structure-like and a process-like perspective. In the present article, we outline theoretical foundations of goal conflict from two perspectives: a structure- and a process-like perspective. Based on a comparative analysis and integration of these two perspectives, we systematically review empirical studies on goal conflict over 30 years of research. In doing so, we identify and discuss important conceptual dimensions of goal conflict, namely, goal conflict as a cognitive construct and an experiential instance, a focus on goal interrelations or on specific goal properties, and resource vs. inherent conflict, and the potential of these distinctions to further research on goal conflict. Finally, we present major challenges and pose questions that need to be addressed by future research.

    Despite a better understanding of the pathophysiology of asthma, presence of reliable diagnostic tools, availability of a wide array of effective and affordable inhaled drugs and simplified national and international asthma management guidelines, asthma remains poorly managed in India. The Asia-Pacific Asthma Insight and Management (AP-AIM) study was aimed at understanding the characteristics of asthma, current management, level of asthma control and its impact on quality of life across Australia, China, Hong Kong, India, Malaysia, Singapore, South Korea, Taiwan and Thailand. This paper describes the results of asthma management issues in India in detail and provides a unique insight into asthma in India. The AP-AIM India study was conducted in eight urban cities in India, viz: Ajmer, Delhi, Kolkata, Rourkela, Chennai, Mangalore, Mumbai and Rajkot from February to July 2011. Face-to-face interviews were conducted in adult asthmatics and parents of asthmatic children between the ages of 12 and 17 years with a confirmed diagnosis or a treatment history of 1 year for asthma. Four hundred asthmatics (M:F::1:1.273), with a mean age of 50 ± 17.8 years, from across India were studied. 91% of the asthmatics in India perceived their asthma to be under control, however, none of the asthmatics had controlled asthma by objective measures. Asthmatics in India believed that their asthma was under control if they have up to 2 emergency doctor visits a year. The quality of life of these patients was significantly affected with 93% school/work absenteeism and a loss of 50% productivity. Seventy-five percent of the asthmatics have never had a lung function test. The common triggers for asthmatics in India were dust (49%) and air pollution (49%), while only 5% reported of pollen as triggers. Eighty-nine percent of Indian asthmatics reported an average use of oral steroids 10.5 times a year. Only 36% and 50% of Indian asthmatics used controller and rescue inhalers with a majority

    Food portion-sizes might be a promising starting point for interventions targeting obesity. The purpose of this qualitative study was to assess how representatives of point-of-purchase settings perceived the feasibility of interventions aimed at portion-size. Semi-structured interviews were conducted with 22 representatives of various point-of-purchase settings. Constructs derived from the diffusion of innovations theory were incorporated into the interview guide. Each interview was recorded and transcribed verbatim. Data were coded and analysed with Atlas.ti 5.2 using the framework approach. According to the participants, offering a larger variety of portion-sizes had the most relative advantages, and reducing portions was the most disadvantageous. The participants also considered portion-size reduction and linear pricing of portion-sizes to be risky. Lastly, a larger variety of portion-sizes, pricing strategies and portion-size labelling were seen as the most complex interventions. In general, participants considered offering a larger variety of portion-sizes, portion-size labelling and, to a lesser extent, pricing strategies with respect to portion-sizes as most feasible to implement. Interventions aimed at portion-size were seen as innovative by most participants. Developing adequate communication strategies about portion-size interventions with both decision-makers in point-of-purchase settings and the general public is crucial for successful implementation.

    Full Text Available Abstract Background Exposure to pollution is a significant risk to human health. However few studies have attempted to identify the types of policy interventions that can reduce the health risks of pollution exposure in the United States. The study objective was to conduct a realist review of policy interventions conducted or aimed at reducing chemical exposures in humans or the environment where exposure was measured. Methods A systematic literature search identified published articles that assessed policy interventions using exposure data. Two coders independently extracted data from the studies, assessing methods, context, details of interventions, outcomes, and risks of bias. Data were analyzed iteratively and manually to identify the most effective and transferrable types of interventions. The reasons for variability in the success of different interventions were explored. Results The review found that regulatory interventions that eliminate point sources of pollution appeared to reduce exposure to environmental hazards. Regular monitoring to provide environmental and human exposure data helped assess compliance with the regulatory standards. Educational and economic interventions were less successful. Conclusions Although some types of regulatory interventions appear to reduce exposures, our findings are limited by the nature of existing interventions, the weaknesses of the study designs used in the literature, and the lack of details on implementation. Information on contextual factors that influence implementation would assist with future reviews and could help identify effective interventions.

  15. Can inequality be tamed through boundary work? A qualitative study of health promotion aimed at reducing health inequalities.

    2017-07-01

    This paper examines the organisational dynamics that arise in health promotion aimed at reducing health inequalities. The paper draws on ethnographic fieldwork among public health officers in Danish municipalities and qualitative interviews from an evaluation of health promotion programmes targeting homeless and other marginalised citizens. Analytically, we focus on 'boundary work', i.e. the ways in which social and symbolic boundaries are established, maintained, transgressed and negotiated, both at the administrative level and among frontline professionals. The paper discusses three types of boundary work: (i) demarcating professional domains; (ii) setting the boundaries of the task itself; and (iii) managing administrative boundaries. The main argument is that the production, maintenance and transgression of these three types of boundaries constitute central and time-consuming aspects of the practices of public health professionals, and that boundary work constitutes an important element in professional practices seeking to 'tame a wicked problem', such as social inequalities in health. A cross-cutting feature of the three types of boundary work is the management of the divide between health and social issues, which the professionals seemingly seek to uphold and transgress at the same time. The paper thus contributes to ongoing discussions of intersectoral action to address health inequalities. Furthermore, it extends the scope and application of the concept of boundary work in the sociology of public health by suggesting that the focus in previous research on professional demarcation be broadened in order to capture other types of boundaries that shape, and are shaped by, professional practices.

    Evaluating the translatability and feasibility of an intervention program has become as important as determining the effectiveness of the intervention. To evaluate the applicability of a 3-month jump-landing training program in basketball players, using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. Randomized controlled trial. National and regional basketball teams. Twenty-four teams of the second highest national division and regional basketball divisions in Flanders, Belgium, were randomly assigned (1:1) to a control group and intervention group. A total of 243 athletes (control group = 129, intervention group = 114), ages 15 to 41 years, volunteered. All exercises in the intervention program followed a progressive development, emphasizing lower extremity alignment during jump-landing activities. The results of the process evaluation of the intervention program were based on the 5 dimensions of the RE-AIM framework. The injury incidence density, hazard ratios, and 95% confidence intervals were determined. The participation rate of the total sample was 100% (reach). The hazard ratio was different between the intervention group and the control group (0.40 [95% confidence interval = 0.16, 0.99]; effectiveness). Of the 12 teams in the intervention group, 8 teams (66.7%) agreed to participate in the study (adoption). Eight of the participating coaches (66.7%) felt positively about the intervention program and stated that they had implemented the training sessions of the program as intended (implementation). All coaches except 1 (87.5%) intended to continue the intervention program the next season (maintenance). Compliance of the coaches in this coach-supervised jump-landing training program was high. In addition, the program was effective in preventing lower extremity injuries.

    Through data collection methods using a holistic approach that focuses on variables in a natural setting, qualitative research methods seek to understand participants' perceptions and interpretations. Common qualitative research methods include ethnography, phenomenology, grounded theory, and historic research. Another type of methodology that has a similar qualitative approach is case study research, which seeks to understand a phenomenon or case from multiple perspectives within a given real-world context.

    Few studies to date have explored the relationship between the built environment and physical activity specifically in rural settings. The Ontario Public Health Standards policies mandate that health units in Ontario address the built environment; however, it is unclear how public health practitioners are integrating the built environment into public health interventions aimed at improving physical activity in chronic disease prevention programs. This descriptive qualitative study explored interventions that have or are being implemented which address the built environment specifically related to physical activity in rural Ontario health units, and the impact of these interventions. Data were collected through twelve in-depth semi-structured interviews with rural public health practitioners and managers representing 12 of 13 health units serving rural communities. Key themes were identified using qualitative content analysis. Themes that emerged regarding the types of interventions that health units are employing included: Engagement with policy work at a municipal level; building and working with community partners, committees and coalitions; gathering and providing evidence; developing and implementing programs; and social marketing and awareness raising. Evaluation of interventions to date has been limited. Public health interventions, and their evaluations, are complex. Health units who serve large rural populations in Ontario are engaging in numerous activities to address physical activity levels. There is a need to further evaluate the impact of these interventions on population health.

    It is considered general knowledge among physicians and epidemiologists that biological and social aspects associated with being male or female have a strong influence on health and disease. Integrating these aspects into research is necessary to counteract the problems--including ethical problems--resulting from a different evidence basis for men and women. From January 2011 to June 2014 the Federal Ministry of Education and Research supported the network "Sex-/Gender-Sensitive Research in Epidemiology, Neuroscience and Genetics/Cancer Research" with three subprojects, which aimed to promote gender-sensitive research practices. The concepts and results are presented in this article. The subproject gathered data (literature analyses, questionnaires) and offered programs for young scientists. Experiences and results were collected and generalized, for instance, in the form of definitions of terms. 50 young scientists have taken part in the training program, identifying associations and barriers in sex-/gender-sensitive research. Among others, a working definition for "sex-/gender-sensitive research" was developed, as well as definitions for the terms "sex-specific" (for biological characteristics that are specific to men or women) and "sex-/gender-dependent" or "sex-/gender-associated" (for biological and social factors, for which the extent of occurrence differs between the sexes). The concepts realized by the network are well suited to stimulate further development and discussions. The definition of terms is an important base for a productive and high-yielding interdisciplinary collaboration.

    Combining limb and nadir satellite observations of Polar Mesospheric Clouds (PMCs) has long been recognized as problematic due to differences in observation geometry, scattering conditions, and retrieval approaches. This study offers a method of comparing PMC brightness observations from the nadir-viewing Aeronomy of Ice in the Mesosphere (AIM) Cloud Imaging and Particle Size (CIPS) instrument and the limb-viewing Odin Optical Spectrograph and InfraRed Imaging System (OSIRIS). OSIRIS and CIPS measurements are made comparable by defining a common volume for overlapping OSIRIS and CIPS observations for two northern hemisphere (NH) PMC seasons: NH08 and NH09. We define a scattering intensity quantity that is suitable for either nadir or limb observations and for different scattering conditions. A known CIPS bias is applied, differences in instrument sensitivity are analyzed and taken into account, and effects of cloud inhomogeneity and common volume definition on the comparison are discussed. Not accounting for instrument sensitivity differences or inhomogeneities in the PMC field, the mean relative difference in cloud brightness (CIPS - OSIRIS) is -102 ± 55%. The differences are largest for coincidences with very inhomogeneous clouds that are dominated by pixels that CIPS reports as non-cloud points. Removing these coincidences, the mean relative difference in cloud brightness reduces to -6 ± 14%. The correlation coefficient between the CIPS and OSIRIS measurements of PMC brightness variations in space and time is remarkably high, at 0.94. Overall, the comparison shows excellent agreement despite different retrieval approaches and observation geometries.

    The majority of young people do not meet the recommendations on physical activity for health. New innovative ways to motivate young people to adopt a physically active lifestyle are needed. The study aimed to study the feasibility of an automated, gamified, tailored Web-based mobile service aimed at physical and social activation among young men. A population-based sample of 496 young men (mean age 17.8 years [standard deviation 0.6]) participated in a 6-month randomized controlled trial (MOPO study). Participants were randomized to an intervention (n=250) and a control group (n=246). The intervention group was given a wrist-worn physical activity monitor (Polar Active) with physical activity feedback and access to a gamified Web-based mobile service, providing fitness guidelines, tailored health information, advice of youth services, social networking, and feedback on physical activity. Through the trial, the physical activity of the men in the control group was measured continuously with an otherwise similar monitor but providing only the time of day and no feedback. The primary outcome was the feasibility of the service based on log data and questionnaires. Among completers, we also analyzed the change in anthropometry and fitness between baseline and 6 months and the change over time in weekly time spent in moderate to vigorous physical activity. Mobile service users considered the various functionalities related to physical activity important. However, compliance of the service was limited, with 161 (64.4%, 161/250) participants visiting the service, 118 (47.2%, 118/250) logging in more than once, and 41 (16.4%, 41/250) more than 5 times. Baseline sedentary time was higher in those who uploaded physical activity data until the end of the trial (P=.02). A total of 187 (74.8%, 187/250) participants in the intervention and 167 (67.9%, 167/246) in the control group participated in the final measurements. There were no differences in the change in anthropometry and

    The solo-irradiation of thermal neutrons has been applied for brain cancer and malignant melanoma in the boron neutron capture therapy (BNCT) at the medical irradiation facility of Kyoto University Reactor (KUR), from the first clinical trial in 1974. In 1997, after the facility remodeling, the application of the mix-irradiation of thermal and epi-thermal neutrons was started, and the depth dose distribution for brain cancer has been improved in some degree. In 2001, the solo-irradiation of epi-thermal neutrons also started. It is specially mentioned that the application to oral cancers started at the same time. The BNCT clinical trial using epi-thermal neutron irradiation at KUR, amounts to twelve as of March 2003. The seven trials; more than a half of the total trials, are for oral cancers. From this fact, we think that the wider application to the other cancers is required for the future prosperity of BNCT. The cancers applied for BNCT in KUR at the present time, are brain cancer, melanoma and oral cancers, as mentioned above. The cancers, expected to be applied in near future, are liver cancer, pancreas cancer, lung cancer, tongue cancer, breast cancer, etc.. Any cancer is almost incurable by the other therapy including the other radiation therapy. In the wider application of BNCT to these cancers, the dose-distribution control suitable to each cancer and/or each part, is important. The introduction of multi-directional and/or multi-divisional irradiation is also needed. Here, a physical and engineering study using two-dimensional transport calculation and three-dimensional Monte-Carlo simulation for the irradiation techniques in BNCT aiming for wider application is reported

  7. Rethinking Partnerships with the Aim of Producing Knowledge with Practical Relevance: a Case Study in the Field of Ecological Restoration

    Directory of Open Access Journals (Sweden)

    2008-12-01

    Full Text Available Researchers in conservation biology and restoration ecology often work in partnership with local actors to increase the practical relevance of the knowledge they produce. Although an academic mode of knowledge production is essential in research for a better understanding of biological systems, it often fails to produce frameworks and methodologies having practical relevance that can be used in conservation and restoration programs. The involvement of researchers in collective plans of action is supposed to contribute to the production of a more contextualized form of knowledge. In this paper, we report our experience of partnership research in an ecological restoration project. We show that changing our mode of knowledge production to one that produces knowledge having more practical relevance requires a particular spectrum of partners and reflexive communication between all the partners. We advocate the need for participatory approaches that favor collective and reflexive processes of problem finding and problem solving in conservation and restoration projects. Putting such processes into practice is not only a challenge for researchers but also for their partners, and presupposes a profound transformation of their roles.

    The research reactors, of which the fuel elements are of MTR type, functions presently, almost in their majority with high U-235 enrichment. The fear that those fuel elements might generate a considerabLe proliferation of nuclear weapons rendered almost mandatory the conversion of highly enriched fuel elements to a low U-235 enrichment. As the IEA-R1 reactor of IPEN is operating with highly enriched fuel elements a study aiming at this conversion was done. The problems related to the conversion and the results obtained, demonstrated the technical viabilty for its realization. (E.G.) [pt

    Health services research is a well-articulated research methodology and can be a powerful vehicle to implement sustainable health service reform. This paper presents a summary of a five-year collaborative program between stakeholders and researchers that led to sustainable improvements in the maternity services for remote-dwelling Aboriginal women and their infants in the Top End (TE) of Australia. A mixed-methods health services research program of work was designed, using a participatory approach. The study area consisted of two large remote Aboriginal communities in the Top End of Australia and the hospital in the regional centre (RC) that provided birth and tertiary care for these communities. The stakeholders included consumers, midwives, doctors, nurses, Aboriginal Health Workers (AHW), managers, policy makers and support staff. Data were sourced from: hospital and health centre records; perinatal data sets and costing data sets; observations of maternal and infant health service delivery and parenting styles; formal and informal interviews with providers and women and focus groups. Studies examined: indicator sets that identify best care, the impact of quality of care and remoteness on health outcomes, discrepancies in the birth counts in a range of different data sets and ethnographic studies of 'out of hospital' or health centre birth and parenting. A new model of maternity care was introduced by the health service aiming to improve care following the findings of our research. Some of these improvements introduced during the five-year research program of research were evaluated. Cost effective improvements were made to the acceptability, quality and outcomes of maternity care. However, our synthesis identified system-wide problems that still account for poor quality of infant services, specifically, unacceptable standards of infant care and parent support, no apparent relationship between volume and acuity of presentations and staff numbers with the

    The present paper reports on a 5-year follow-up of a randomized reading intervention in grade 3 in Sweden. An intervention group (n = 57) received daily training for 12 weeks in phoneme/grapheme mapping, reading comprehension and reading speed, whereas a control group (n = 55) participated in ordinary classroom activities. The main aim was to investigate if there were remaining effects of the intervention on reading-related skills. Previous analyses showed that the intervention group performed significantly better than the control group on spelling, reading speed, reading comprehension and phoneme awareness at the immediate post-test with sustained effects 1 year later. Results from the 5-year follow-up show that the only significant difference between the intervention (n = 47) and the control group (n = 37) was on word decoding. There was also a significant interaction effect of group assignment and initial word decoding, in the way that the lowest-performing students benefitted the most from the intervention. Another aim was to examine if the children identified in a screening (n = 2212) as poor readers in grade 2 still performed worse than typical readers. The analyses showed that the typically developing students (n = 66) outperformed the students identified as poor readers in grade 2 on working memory, spelling, reading comprehension and word decoding.

    2018-01-01

    Health technology solutions are too often implemented without a true understanding of the system-level problem they seek to address, resulting in excessive costs, poor adoption, ineffectiveness, and ultimately failure. Before implementing or adopting health care innovations, stakeholders should complete a thorough assessment to ensure effectiveness and value. In this article, we describe how to evaluate the impact of a health technology innovation through the 4 dimensions of care outlined by the Quadruple Aim Framework, using our experience with the Champlain Building Access to Specialists through eConsultation (BASE) eConsult service as a case example. A descriptive overview of data was collected between April 1, 2011, and August 31, 2017, using 4 dimensions of care outlined by the Quadruple Aim Framework: patient experience, provider experience, costs, and population health. Findings were drawn from use data, primary care provider closeout surveys, surveys/interviews with patients and provider, and costing data. Overall, patients have received access to specialist advice within days and find the advice useful in 86% of cases. Provider experience is very positive, with satisfaction ratings of high/very high value in 94% of cases. The service cost a weighted average of $47.35/case, compared with $133.60/case for traditional referrals. In total, 1,299 primary care providers have enrolled in the service, completing 28,838 cases since 2011. Monthly case volumes have grown from an average of 13 cases/month in 2011 to 969 cases/month in 2016. The eConsult service has been widely adopted in our region and is currently expanding to new jurisdictions across Canada. However, although we successfully demonstrated eConsult's impact on patient experience, provider satisfaction, and reducing costs, we met several challenges in evaluating its impact on population health. More work is needed to evaluate eConsult's impact on key population health metrics (eg, mortality, morbidity

    -independent factors, as well as our investigation of ways to improve the clinical evaluation of the disease. Our research was prompted by the multifactorial nature of glaucoma. There is a high degree of variability in the pattern and speed of the progression of visual field defects in individual patients, presenting a major obstacle for successful clinical trials. To overcome this, we classified the eyes of glaucoma patients into 4 types, corresponding to the 4 patterns of glaucomatous optic nerve head morphology described: by Nicolela et al. and then tested the validity of this method by assessing the uniformity of clinical features in each group. We found that in normal tension glaucoma (NTG) eyes, each disc morphology group had a characteristic location in which the loss of circumpapillary retinal nerve fiber layer thickness (cpRNFLT; measured with optical coherence tomography: OCT) was most likely to occur. Furthermore, the incidence of reductions in visual acuity differed between the groups, as did the speed of visual field loss, the distribution of defective visual field test points, and the location of test points that were most susceptible to progressive damage, measured by Humphrey static perimetry. These results indicate that Nicolela's method of classifying eyes with glaucoma was able to overcome the difficulties caused by the diverse nature of the disease, at least to a certain extent. Building on these findings, we then set out to identify sectors of the visual field that correspond to the distribution of retinal nerve fibers, with the aim of detecting glaucoma progression with improved sensitivity. We first mapped the statistical correlation between visual field test points and cpRNFLT in each temporal clock-hour sector (from 6 to 12 o'clock), using OCT data from NTG patients. The resulting series of maps allowed us to identify areas containing visual field test points that were prone to be affected together as a group. We also used a similar method to identify visual

    Results of a seismic risk assessment study are often applied and interpreted by users unspecialised on the topic or lacking a scientific background. In this context, the availability of tools that help translating essentially scientific contents to broader audiences (such as decision makers or civil defence officials) as well as representing and managing results in a user-friendly fashion, are on indubitable value. On of such tools is the visualization tool VISOR-RISNA, a web tool developed within the RISNA project (financed by the Emergency Agency of Navarre, Spain) for regional seismic risk assessment of Navarre and the subsequent development of emergency plans. The RISNA study included seismic hazard evaluation, geotechnical characterization of soils, incorporation of site effects to expected ground motions, vulnerability distribution assessment and estimation of expected damage distributions for a 10% probability of exceedance in 50 years. The main goal of RISNA was the identification of higher risk area where focusing detailed, local-scale risk studies in the future and the corresponding urban emergency plans. A geographic information system was used to combine different information layers, generate tables of results and represent maps with partial and final results. The visualization tool VISOR-RISNA is intended to facilitate the interpretation and representation of the collection of results, with the ultimate purpose of defining actuation plans. A number of criteria for defining actuation priorities are proposed in this work. They are based on combinations of risk parameters resulting from the risk study (such as expected ground motion and damage and exposed population), as determined by risk assessment specialists. Although the values that these parameters take are a result of the risk study, their distribution in several classes depends on the intervals defined by decision takers or civil defense officials. These criteria provide a ranking of

    Mitsubishi Heavy Industries, Ltd. (MHI) has been studying on MHI original High Temperature Gas cooled Reactor (HTGR), namely MHR-50/100, for commercialization with supported by JAEA. In the heat transfer system, steam generator (SG) is one of the most important components because it should be imposed a function of heat transfer from reactor power to steam turbine system and maintaining a nuclear grade boundary. Then we especially focused an effort of a design study on the SG having robustness against water ingress accident based on our design experience of PWR, FBR and HTGR. In this study, we carried out a sensitivity analysis from the view point of economic and plant efficiency. As a result, the SG design parameter of helium inlet/outlet temperature of 750 deg. C/300 deg. C, a side-by-side layout and one unit of SG attached to a reactor were selected. In the next, a design improvement of SG was carried out from the view point of securing the level of inherent safety without reliance on active steam dump system during water ingress accident considering the situation of the Fukushima nuclear power plant disaster on March 11, 2011. Finally, according to above basic design requirement to SG, we performed a conceptual design on adapting themes of SG structure improvement. (authors)

  1. Fast diffusion tensor magnetic resonance imaging of the mouse brain at ultrahigh-field: aiming at cohort studies.

    Directory of Open Access Journals (Sweden)

    Hans-Peter Müller

    Full Text Available INTRODUCTION: In-vivo high resolution diffusion tensor imaging (DTI of the mouse brain is often limited by the low signal to noise ratio (SNR resulting from the required small voxel sizes. Recently, cryogenically cooled resonators (CCR have demonstrated significant increase of the effective SNR. It is the objective of this study to enable fast DTI of the mouse brain. In this context, CCRs appear attractive for SNR improvement. METHODS: Three mice underwent a DTI examination at 156²×250 µm³ spatial resolution with a CCR at ultrahigh field (11.7T. Diffusion images were acquired along 30 gradient directions plus 5 references without diffusion encoding, resulting in a total acquisition time of 35 minutes. For comparison, mice additionally underwent a standardized 110 minutes acquisition protocol published earlier. Fractional anisotropy (FA and fiber tracking (FT results including quantitative tractwise fractional anisotropy statistics (TFAS were qualitatively and quantitatively compared. RESULTS: Qualitative and quantitative assessment of the calculated fractional anisotropy maps and fibre tracking results showed coinciding outcome comparing 35 minute scans to the standardized 110 minute scan. Coefficients of variation for ROI-based FA-comparison as well as for TFAS revealed comparable results for the different scanning protocols. CONCLUSION: Mouse DTI at 11.7 T was performed with an acquisition time of approximately 30 minutes, which is considered feasible for cohort studies. The rapid acquisition protocol reveals reliable and reproducible FA-values and FT reconstructions, thus allowing an experimental setup for in-vivo large scale whole brain murine DTI cohort studies.

    2010-02-01

    This qualitative study assessed consumers' opinions of food portion sizes and their attitudes toward portion-size interventions located in various point-of-purchase settings targeting overweight and obese people. Eight semi-structured focus group discussions were conducted with 49 participants. Constructs from the diffusion of innovations theory were included in the interview guide. Each focus group was recorded and transcribed verbatim. Data were coded and analyzed with Atlas.ti 5.2 using the framework approach. Results showed that many participants thought that portion sizes of various products have increased during the past decades and are larger than acceptable. The majority also indicated that value for money is important when purchasing and that large portion sizes offer more value for money than small portion sizes. Furthermore, many experienced difficulties with self-regulating the consumption of large portion sizes. Among the portion-size interventions that were discussed, participants had most positive attitudes toward a larger availability of portion sizes and pricing strategies, followed by serving-size labeling. In general, reducing package serving sizes as an intervention strategy to control food intake met resistance. The study concludes that consumers consider interventions consisting of a larger variety of available portion sizes, pricing strategies and serving-size labeling as most acceptable to implement.

    The influence of main parameters involved in the method of silicon nitride attainment by carbothermal reduction of silica followed by nitridation were studied in isothermal experiments of fine powder mixtures of silica and graphite in a nitrogen gas flow. The time, temperature, rate C/SiO 2 and flow of nitrogen were varied since they are the main parameters involved in this kind of reaction. The products of reaction were analysed by X-ray diffraction to identify the crystalline phases and as a result was obtained the nucleation of silicon nitride phase. Meanwhile, corroborating prior results, we verified to be difficult the progress of the reaction and the inhibition of formation of silicon carbide phase, the last one being associated to the formation of silicon nitride phase due to thermodynamic matters [pt

    The work proposed herein follows on directly from the existing 3 year grant and the request for funding is for 12 months to allow completion of this work and graduation of current students supported by DOE. The three primary projects are as follows. 1.) A comparative study of the reactivity of LMg(OR) (solvent), where L= a β-diiminate or pyrromethene ligand, in the ring-opening of cyclic esters. 2.) The homopolymerization of expoxides, particularly propylene oxide and styrene oxide, and their copolymerizations with carbon dioxide or organic anhydrides to yield polycarbonates or polyesters, respectively. 3.) The development of well-defined bismuth (III) complexes for ring-opening polymerizations that are tolerant of both air and water. In each of these topics special emphasis is placed on developing a detailed mechanistic understanding of the ring-opening event and how this is modified by the employment of specific metal and ligand combinations. This document also provides a report on findings of the past grant period that are not yet in the public domain/published and shows how the proposed work will bring the original project to conclusion.

    The purpose of this investigation was to examine treatment adherence to medication and lifestyle recommendations among pediatric migraine patients using electronic monitoring systems. Nonadherence to medical treatment is a significant public health concern, and can result in poorer treatment outcomes, decreased cost-effectiveness of medical care, and increased morbidity. No studies have systematically examined adherence to medication and lifestyle recommendations in adolescents with migraine outside of a clinical trial. Participants included 56 adolescents ages 11-17 who were presenting for clinical care. All were diagnosed with migraine with or without aura or chronic migraine and had at least 4 headache days per month. Medication adherence was objectively measured using electronic monitoring systems (Medication Event Monitoring Systems technology) and daily, prospective self-report via personal electronic devices. Adherence to lifestyle recommendations of regular exercise, eating, and fluid intake were also assessed using daily self-report on personal electronic devices. Electronic monitoring indicates that adolescents adhere to their medication 75% of the time, which was significantly higher than self-reported rates of medication adherence (64%). Use of electronic monitoring of medication detected rates of adherence that were significantly higher for participants taking once daily medication (85%) versus participants taking twice daily medication (59%). Average reported adherence to lifestyle recommendations of consistent noncaffeinated fluid intake (M = 5 cups per day) was below recommended levels of a minimum of 8 cups per day. Participants on average also reported skipping 1 meal per week despite recommendations of consistently eating three meals per day. Results suggest that intervention focused on adherence to preventive treatments (such as medication) and lifestyle recommendations may provide more optimal outcomes for children and adolescents with

    After the discovery of a Reactor Vessel Head Degradation at Davis Besse, the NRC, a regulatory body in the U.S., launched an evaluation scheme regarding nuclear stations' Safety Culture. In this evaluation, the NRC examines every inspection finding of conventional Reactor Oversight Program inspections to find out what was the most dominant causal factor with SC aspects. There are no similar analyses of this kind opened to public. This study has its goal of obtaining some useful clue for realizing how to project SC enhancement activities, by making analysis on every ROP inspection finding as well as collecting examples of good practices in improving organizational performance of stations in the U.S. As for the inspection results of ROP, there are no obvious change in the trend of number and types of ROP findings. On the other hand, because of the variety in average number of findings at stations, we could assume that actual condition of SC within a particular station quite differs from other stations. Looking at ROP reports minutely, you may realize that all U.S. stations have been making great effort to improve the efficiency of its Corrective Action Program which is regarded as the key ability to identify and fix undesirable incidents broke out at the station. It is a noteworthy aspect that CAP is not a simple program of quality assurance but also one of the items in power stations to be improved continuously. The concrete elements of this process are realizing current organizational condition by series of Performance Indicators, setting the next goals with the PIs, also evaluating the degree of the achievements with them, and modifying or re-defining new goal of the organization in accordance with new situation. This idea is introduced into broad range of organizational activities all over the U.S., which assure their improvement to be objective and effective. Simultaneously, such way of operation have its staff devoted in own responsibility, which eventually

    Among adult kidney transplant recipients, non-adherence to immunosuppressive medications is the leading predictor of poor outcomes, including rejection, kidney loss, and death. An alarming one-third of kidney transplant patients experience medication non-adherence even though the problem is preventable. Existing adherence interventions have proven marginally effective for those with acute and chronic illnesses and ineffective for adult kidney transplant recipients. Our purpose is to describe the design and methods of the MAGIC (Medication Adherence Given Individual SystemCHANGE™) trial We report the design of a randomized controlled trial with an attention-control group to test an innovative 6-month SystemCHANGE™ intervention designed to enhance immunosuppressive medication adherence in adult non-adherent kidney transplant recipients from two transplant centers. Grounded in the Socio-Ecological Model, SystemCHANGE™ seeks to systematically improve medication adherence behaviors by identifying and shaping routines, involving supportive others in routines, and using medication taking feedback through small patient-led experiments to change and maintain behavior. After a 3-month screening phase of 190 eligible adult kidney transplant recipients, those who are adherent as measured by electronic monitoring, will be randomized into a 6-month SystemCHANGE™ intervention or attention-control phase, followed by a 6-month maintenance phase without intervention or attention. Differences in adherence between the two groups will be assessed at baseline, 6 months (intervention phase) and 12 months (maintenance phase). Adherence mediators (social support, systems-thinking) and moderators (ethnicity, perceived health) are examined. Patient outcomes (creatinine/blood urea nitrogen, infection, acute/chronic rejection, graft loss, death) and cost effectiveness are to be examined. Based on the large effect size of 1.4 found in our pilot study, intervention shows great promise

    The purpose of this project was to study the feasibility of reusing major components of a software system that had been used to control the operations of a spacecraft launched in the 1980s. The study was done in the context of a ground data processing system that was to be rehosted from a large mainframe to an inexpensive workstation. The study concluded that a systematic approach using inexpensive tools could aid in the reengineering process by identifying a set of certified reusable components. The study also developed procedures for determining duplicate versions of software, which were created because of inadequate naming conventions. Such procedures reduced reengineering costs by approximately 19.4 percent.

    This is the final technical report for the AIMES project. Many important advances in science and engineering are due to large-scale distributed computing. Notwithstanding this reliance, we are still learning how to design and deploy large-scale production Distributed Computing Infrastructures (DCI). This is evidenced by missing design principles for DCI, and an absence of generally acceptable and usable distributed computing abstractions. The AIMES project was conceived against this backdrop, following on the heels of a comprehensive survey of scientific distributed applications. AIMES laid the foundations to address the tripartite challenge of dynamic resource management, integrating information, and portable and interoperable distributed applications. Four abstractions were defined and implemented: skeleton, resource bundle, pilot, and execution strategy. The four abstractions were implemented into software modules and then aggregated into the AIMES middleware. This middleware successfully integrates information across the application layer (skeletons) and resource layer (Bundles), derives a suitable execution strategy for the given skeleton and enacts its execution by means of pilots on one or more resources, depending on the application requirements, and resource availabilities and capabilities.

    This article uses an exemplar of phenomenological research of middle school boys, experiences of being bullied as applied philosophy and science to illuminate the intersection of the moral and scientific realms for theory-oriented research and practice. As a consequence, a clear foundation for advancing nursing science and envisioning innovative nursing practice with boys who experience being bullied is provided. Included is a weaving together of phenomenological perspective for research and practice, Roger's (nursing) Science of Unitary Human Beings (SUHB), and SUHB-derived middle range theories of self-transcendence and power.

    Many important advances in science and engineering are due to large-scale distributed computing. Notwithstanding this reliance, we are still learning how to design and deploy large-scale production Distributed Computing Infrastructures (DCI). The AIMES project was conceived against this backdrop, following on the heels of a comprehensive survey of scienti c distributed applications [1]. The survey established, arguably for the rst time, the relationship between infrastructure and scienti c distributed applications. It examined well known contributors to the complexity associated with infrastructure, such as inconsistent internal and external interfaces, and demonstrated the correlation with application brittleness. It discussed how infrastructure complexity reinforces the challenges inherent in developing distributed applications.

    Mindfulness-based interventions are reported to be highly acceptable and have positive effects on youth, yet most are clinic- or school-based aimed at emotional regulation or academic performance. To provide flexible program delivery, we developed and tested a standalone mindfulness-based app aimed at improving weight-related behaviors (eg, diet, physical activity, sleep) in adolescents. Our objective was to assess the feasibility, acceptability, and utility of a mindfulness-based mobile app. In a single-arm pilot study, 15 adolescents (14-18 years) were prompted to access the app once a day, every day for 6 weeks. Outcomes were measured by in-app and poststudy surveys, and descriptive statistical analyses were performed. Time within a mindfulness state was self-reported during weekly timed practices. The app was rated highly for content and encouraging the practice of activities to promote mindfulness states. Teens reported increased awareness of eating behaviors and high adherence, particularly during physically active practices. Average self-reported time spent in a mindfulness state increased 2.5 times by week 6 (78 [SD 17] seconds) compared to week 1 (31 [SD 21] seconds). The high acceptability and utility ratings of the app, increases in reported time in mindfulness states, and high frequency of participation, including mindful eating and physical activity, suggest the mindfulness-based mobile app has the potential to improve awareness of weight-related behaviors. ©Tami Turner, Melanie Hingle.

    There is increasing focus on building safety into anaesthesia practice, with excellence in anaesthesia as an aspirational goal. Non-technical skills are an important factor in excellence and improved patient safety, though there have been few systematic attempts at integrating them into anaesthesia nursing education. This study aimed to test the reliability of NANTS-no, a specially adapted behavioural marker system for nurse anaesthetists in Norway, and explore the development of non-technical skills in student nurse anaesthetists. The pre-test post-test design incorporated a 10-week simulation-based programme, where non-technical skills in 14 student nurse anaesthetists were rated on three different occasions during high-fidelity simulation, before and after taking part in a training course. NANTS-no demonstrated high overall inter-rater reliability (ICC = 0.91), high test-retest reliability (ICC = 0.94) and good internal consistency (Cronbach's α of 0.85-0.92). A significant improvement was demonstrated across all categories of non-technical skills, with greatest improvements between the first and third and second and third sessions. There was also a significant improvement in two categories between the first and second sessions. NANTS-no is therefore suitable for assessing non-technical skills during simulation training in anaesthesia nursing education. More research is needed to validate its use in clinical practice.

    The Internet is an attractive medium for delivering individualized, computer-tailored behavior change interventions to large numbers of people. However, the actual numbers of people reached seem to fall behind the high expectations. Insight into factors that determine use of and exposure to these Internet interventions is important to be able to increase the reach and improve exposure. The aim was to identify potentially important factors that determine whether adults visit an Internet-delivered behavior change intervention, extend their visit, and revisit the intervention. A systematic, three-round Delphi study was conducted among national and international experts from Internet intervention research and practice, e-marketing/e-commerce, Web design, and technical website development. In the first round, 30 experts completed a structured, open-ended online questionnaire assessing factors that were, in their opinion, important for a first visit, an extended visit, a revisit and for effective promotion strategies. Based on the responses in this first questionnaire, a closed-ended online questionnaire was developed for use in the second round. A total of 233 experts were invited to complete this questionnaire. Median and interquartile deviation (IQD) scores were computed to calculate agreement and consensus on the importance of the factors. The factors for which no consensus was obtained (IQD > 1) were included in the third-round questionnaire. Factors with a median score of six or higher and with an IQD word-of-mouth by family and friends, a publicity campaign with simultaneous use of various mass media, and recommendation by health professionals, were indicated as effective ways to encourage adults to visit an Internet intervention. This systematic study identified important factors related to the dissemination of and exposure to Internet interventions aimed at adults. In order to improve optimal use of and exposure to Internet interventions, potential users may

    Full Text Available Over the last forty years, case study research has undergone substantial methodological development. This evolution has resulted in a pragmatic, flexible research approach, capable of providing comprehensive in-depth understanding of a diverse range of issues across a number of disciplines. Change and progress have stemmed from parallel influences of historical transformations in approaches to research and individual researcher's preferences, perspectives, and interpretations of this design. Researchers who have contributed to the development of case study research come from diverse disciplines with different philosophical perspectives, resulting in a variety of definitions and approaches. For the researcher new to using case study, such variety can create a confusing platform for its application. In this article, we explore the evolution of case study research, discuss methodological variations, and summarize key elements with the aim of providing guidance on the available options for researchers wanting to use case study in their work.

    Urbanization is considered to be one of the key drivers of noncommunicable diseases (NCDs) in Thailand and other developing countries. These influences, in turn, may affect an individual's behavior and risk of developing NCDs. The Chiang Mai University (CMU) Health Worker Study aims to provide evidence for a better understanding of the development of NCDs and ultimately to apply the evidence toward better prevention, risk modification, and improvement of clinical care for patients with NCDs and NCD-related conditions. A cross-sectional survey of health care workers from CMU Hospital was conducted between January 2013 and June 2013. Questionnaires, interviews, and physical and laboratory examinations were used to assess urban exposure, occupational shift work, risk factors for NCDs, self-reported NCDs, and other NCD-related health conditions. From 5,364 eligible workers, 3,204 participated (59.7%). About 11.1% of the participants had high blood pressure (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg) and almost 30% were considered to be obese (body mass index ≥25 kg/m(2)). A total of 2.3% had a high fasting blood glucose level (≥126 mg/dL), and the most common abnormal lipid profile was high low-density lipoprotein (≥160 mg/dL), which was found in 19.2% of participants. The study of health workers offers three potential advantages. The first is that the study of migrants was possible. Socioenvironmental influence on NCD risk factors can be explored, as changes in environmental exposures can be documented. Second, it allows the investigators to control for access to care. Access to care is potentially a key confounder toward understanding the development of NCDs. Lastly, a study of health personnel allows easy access to laboratory investigations and potential for long-term follow-up. This enables ascertainment of a number of clinical outcomes and provides potential for future studies focusing on therapeutic and prognostic issues

    Full Text Available Abstract Background Dental caries (decay during childhood is largely preventable however it remains a significant and costly public health concern, identified as the most prevalent chronic disease of childhood. Caries in children aged less than five years (early childhood caries is a rapid and progressive disease that can be painful and debilitating, and significantly increases the likelihood of poor child growth, development and social outcomes. Early childhood caries may also result in a substantial social burden on families and significant costs to the public health system. A disproportionate burden of disease is also experienced by disadvantaged populations. Methods/Design This study involves the establishment of a birth cohort in disadvantaged communities in Victoria, Australia. Children will be followed for at least 18 months and the data gathered will explore longitudinal relationships and generate new evidence on the natural history of early childhood caries, the prevalence of the disease and relative contributions of risk and protective biological, environmental and behavioural factors. Specifically, the study aims to: 1. Describe the natural history of early childhood caries (at ages 1, 6, 12 and 18 months, tracking pathways from early bacterial colonisation, through non-cavitated enamel white spot lesions to cavitated lesions extending into dentine. 2. Enumerate oral bacterial species in the saliva of infants and their primary care giver. 3. Identify the strength of concurrent associations between early childhood caries and putative risk and protective factors, including biological (eg microbiota, saliva, environmental (fluoride exposure and socio-behavioural factors (proximal factors such as: feeding practices and oral hygiene; and distal factors such as parental health behaviours, physical health, coping and broader socio-economic conditions. 4.

    Full Text Available Abstract The present research focuses on the investigation of Nezami's tale of "the Evil and the Good" in terms of Greimas's structural semantics. The study aims at the structural analysis of the tale above through the identification of binary oppositions, sequences, the contractual, performative, and disjunctive ones and a good grasp of the structure of Haft Peikar to generalize the research findings to other verse narratives in Persian classic literature. The reason for the selection of Nezami lies in his artifice in narrative production, the narrativity of Haft Peikar and the popularity of the tale of "The Evil and the Good". The research method is descriptive-analytic and the findings are analyzed through content analysis along with Gremasian semantic analysis. The findings reveal that hero (subject and goal (object and the central actors in the narrative and the subject (the good as the base part plays an active role in then narrative with respect to the adaptability of Gremasian approach to the "the Evil and the Good" and conducting more researches, one can confide in Greimas's structural analysis of the other verse narratives.

    2013-01-01

    Fault trees and event trees are widely used in industry to model and to evaluate the reliability of safety systems. Detailed analyzes in nuclear installations require the combination of these two techniques. This study uses the methods of FT (Fault Tree) and ET (Event Tree) to accomplish the PSA (Probabilistic Safety Assessment) in research reactors. According to IAEA (lnternational Atomic Energy Agency), the PSA is divided into Level 1, Level 2 and Level 3. At the Level 1, conceptually, the security systems perform to prevent the occurrence of accidents, At the Level 2, once accidents happened, this Level seeks to minimize consequences, known as stage management of accident, and at Level 3 accident impacts are determined. This study focuses on analyzing the Level 1, and searching through the acquisition of knowledge, the consolidation of methodologies for future reliability studies. The Greek Research Reactor, GRR-1, is a case example. The LOCA (Loss of Coolant Accident) was chosen as the initiating event and from it, using ET, possible accidental sequences were developed, which could lead damage to the core. Moreover, for each of affected systems, probabilities of each event top of FT were developed and evaluated in possible accidental sequences. Also, the estimates of importance measures for basic events are presented in this work. The studies of this research were conducted using a commercial computational tool SAPHIRE. Additionally, achieved results thus were considered satisfactory for the performance or the failure of analyzed systems. (author)

    Argonauta, the only nuclear research reactor situated in Rio de Janeiro, located at the Institute of Nuclear Engineering (IEN), regularly serves a network of users focused on research and development, and also provides its infrastructure for experimental classes and completion work course. Due to increasing demand for non-destructive thermal neutron assays and production of radioisotopes, there is a search for new procedures and/or devices that optimize users' exposure to neutrons. The implementation of mechanisms that allow access to the irradiation channels without the reactor being turned off and with a shielding configuration that limits the occupational doses at this location is very useful for the operation of the reactor. In order to achieve this, the present work proposes the establishment of a neutron beam shutter of the J-9 irradiation channel of the IEN's Argonauta reactor. In a first step, experimental measurements were made in the irradiation channel of the reactor using a BF3 detector, which is coupled to a spectrometer. In this phase, the neutron beam was aligned to the spectrometer, and different materials were used as shields, aiming the attenuation of the beam. To validate and/or change the configuration of the barrier that best meets the material irradiation needs, a second planned phase is involving the neutron flux simulation of the reactor and the various shields with different boundary conditions using the particle transport code, Monte Carlo N-Particle Extended (MCNP- X).

    1994-01-01

    During the past eight months, the authors have made progress in several areas relevant to the eventual use of positron techniques in catalysis research. They have come closer to the completion of their positron microscope, and at the same time have performed several studies in their non-microscopic positron spectrometer which should ultimately be applicable to catalysis. The current status of the efforts in each of these areas is summarized in the following sections: Construction of the positron microscope (optical element construction, data collection software, and electronic sub-assemblies); Doppler broadening spectroscopy of metal silicide; Positron lifetime spectroscopy of glassy polymers; and Positron lifetime measurements of pore-sizes in zeolites

    IN BRIEF Cost-effective innovations to improve health and health care in patients with complex chronic diseases are urgently needed. Mobile health (mHealth) remote monitoring applications (apps) are a promising technology to meet this need. This article reports on a study evaluating patients' use of a tablet device with an mHealth app and a cellular-enabled glucose meter that automatically uploaded blood glucose values to the app. Improvements were observed across all three components of the Patient Protection and Affordable Care Act's "triple aim." Self-rated wellness and numerous quality-of-care metrics improved, billed charges and paid claims decreased, but no changes in clinical endpoints were observed.

    As women's anxiety and the rate of medical intervention in labour and birth continue to increase, it is important to identify how antenatal education can increase women's confidence and their ability to manage the intense sensations of labour. To report a grounded theory study of how the aims, language and actions of yoga for pregnancy teachers may impact upon women's self-efficacy for labour and birth. Yoga for pregnancy classes in three locations were filmed. Semi-structured interviews were undertaken with the teachers to explore what they were trying to achieve in their classes, and how. Interviews and classes were transcribed and analysed using grounded theory. There was considerable consistency in the teachers' aims, the language they used in classes and in their thinking about class structure. Four main themes emerged: creating a sisterhood, modelling labour, building confidence and enhancing learning. Teachers see yoga for pregnancy as a multi-faceted, non-prescriptive intervention that enhances women's physical, emotional and social readiness for labour and birth, and supports women to make their own decisions across the transition to parenthood. Women's self-efficacy for labour is complex and multi-factorial. This study offers insights into the factors which may be involved in increasing it. These include not only traditional elements of yoga such as postures, breathing and meditation, but also the creation of safe, women-only groups where anxieties, experiences and stories can be shared, and pain-coping techniques for labour learned and practised.

    To determine the efficacy of 2 tight control treatment strategies aiming at Simplified Disease Activity Score (SDAI) remission (SDAI ≤ 3.3) compared to 28-joint count Disease Activity Score (DAS28) remission (DAS28 < 2.6) in the prevention of arterial stiffness in patients with early rheumatoid arthritis (RA). This was an open-label study in which 120 patients with early RA were randomized to receive 1 year of tight control treatment. Group 1 (n = 60) aimed to achieve SDAI ≤ 3.3 and Group 2 (n = 60), DAS28 < 2.6. Pulse wave velocity (PWV) and augmentation index (AIx) were measured at baseline and 12 months. A posthoc analysis was also performed to ascertain whether achieving sustained remission could prevent progression in arterial stiffness. The proportions of patients receiving methotrexate monotherapy were significantly lower in Group 1 throughout the study period. At 12 months, the proportions of patients achieving DAS28 and SDAI remission, and the change in PWV and AIx, were comparable between the 2 groups. In view of the lack of differences between the 2 groups, a posthoc analysis was performed at Month 12, including all 110 patients with PWV, to elucidate the independent predictors associated with the change in PWV. Multivariate analysis revealed that achieving sustained DAS28 remission at months 6, 9, and 12 and a shorter disease duration were independent explanatory variables associated with less progression of PWV. With limited access to biologic disease-modifying antirheumatic drugs, treatment efforts toward DAS28 and SDAI remission had similar effects in preventing the progression of arterial stiffness at 1 year. However, achieving sustained DAS28 remission was associated with a significantly greater improvement in PWV. [Clinical Trial registration: Clinicaltrial.gov NCT01768923.].

    A climatological study of the winds and temperature from the Jervis Bay region which commenced in October 1970 has shown the presence of a coastal sea breeze and secondary bay breeze circulation system. In an attempt to define the influence of the Murray's Beach site on the local atmospheric dispersion, special smoke plume photography studies were conducted in the lower atmosphere. In June 1972 a meteorological acoustic sounding research programme was initiated at the Jervis Bay settlement. The aims of the research are to calibrate the sounder in terms of surface wind, turbulence and temperature measurements pertinent to a description of the lower atmospheric dispersion potential. Preliminary results on six months' data have shown encouraging correlations between the acoustic sounder patterns and particularly the wind direction turbulence traces. (author)

    Promoting physical activity and healthy eating habits by structural measures that reach most children in a society is presumably the most sustainable way of preventing development of overweight and obesity in childhood. The main purpose of the present study was to analyse whether policies and plans of action at the central level in municipalities increased the number of measures that aim to promote physical activity and healthy eating habits among schoolchildren aged six to 16. Another purpose was to analyse whether demographic and socio-economic characteristics were associated with the level of such measures. Questionnaires were used to collect data from 25 municipalities and 18 town districts in Stockholm County, Sweden. The questions were developed to capture municipal structural work and factors facilitating physical activity and the development of healthy eating habits for children. Local policy documents and plans of action were gathered. Information regarding municipal demographic and socio-economic characteristics was collected from public statistics. Policy documents and plans of action in municipalities and town districts did not seem to influence the number of measures aiming to promote physical activity and healthy eating habits among schoolchildren in Stockholm County. Municipal demographic and socio-economic characteristics were, however, shown to influence the number of measures. In town districts with a high total population size, and in municipalities and town districts with a high proportion of adults with more than 12 years of education, a higher level of health-promoting measures was found. In municipalities with a high annual population growth, the number of measures was lower than in municipalities with a lower annual population growth. Another key finding was the lack of agreement between what was reported in the questionnaires regarding existence and contents of local policies and plans of action and what was actually found when these

    Full Text Available Type 1 diabetes and celiac disease result from misdirected immune mediated destruction of host cells, and are among the most common chronic diseases in children. Despite changes in incidence over the past 3 decades, little is known about non-genetic risk factors (except for dietary gluten for celiac disease. Norway is among the countries in the world with the highest incidence of these two diseases. We describe here plans and study design for the PAGE study (Prediction of Autoimmune diabetes and celiac disease in childhood by Genes and perinatal Environment. PAGE is a sub-study within the Norwegian Mother and Child Cohort study, including follow-up of more than 100,000 pregnancies. Children who develop type 1 diabetes or celiac disease are identified via linkage to the Norwegian Patient Register and the Norwegian Childhood Diabetes Registry, with complementing information from questionnaires. The overall aim is to test hypotheses about potential non-genetic risk factors for type 1 diabetes and for celiac disease, with focus on factors operating early in life. In addition to a full cohort analysis of factors registered in questionnaires, we will analyse biomarkers in maternal blood plasma and cord blood plasma. Mothers and children will be genotyped for well-established susceptibility polymorphisms. Biomarkers will be analysed in cases and controls within the cohort. Factors to be tested in the full cohort include infant feeding, diet and dietary supplements in the mother during pregnancy and in the child, and use of antibiotics and non-prescription drugs. Biomarkers to be tested include 25-hydroxyvitamin D, markers of immune activation, and small metabolites (metabolomics. We will also explore the potential role of maternal cells in the fetal circulation (maternal microchimerism in later risk of celiac disease and type 1 diabetes.

    Full Text Available ABSTRACT Objective To assess internal consistency and content validity of a questionnaire aimed to assess the stages of Behavioural Lifestyle Changes in a sample of school-aged children and adolescents aged 9 to 17 years-old. Methods This validation study involved 675 schoolchildren from three official school in the city of Bogota, Colombia. A self-administered questionnaire called Behavioural Lifestyle Changes has been designed to explore stages of change regarding to physical activity/exercise, fruit and vegetable consumption, alcohol abuse, tobacco use, and drug abuse. Cronbach-α, Kappa index and exploratory factor analysis were used for evaluating the internal consistency and validity of content, respectively. Results The study population consisted of 51.1% males and the participants’ average age was 12.7±2.4 years-old. Behavioural Lifestyle Changes scored 0.720 (range 0.691 to 0.730 on the Cronbach α and intra-observer reproducibility was good (Kappa=0.71. Exploratory factor analysis determined two factors (factor 1: physical activity/exercise, fruit and vegetable consumption, and factor 2: alcohol abuse tobacco use and drug abuse, explaining 67.78% of variance by the items and six interactions χ2/gL=11649.833; p<0.001. Conclusion Behavioural Lifestyle Changes Questionnaire was seen to have suitable internal consistency and validity. This instrument can be recommended, mainly within the context of primary attention for studying the stages involved in the lifestyle behavioural changes model on a school-based population.

    Background In order to reduce the high maternal mortality ratio, Morocco is strongly committed to strengthen its midwifery professional role. This study aimed to identify barriers that could potentially hinder an action plan to strengthen the midwifery professional role from achieving desired outcomes. We used a conceptual framework, which is derived from Hatem-Asmar’s (1997) framework on the interaction of educational, professional, and sociocultural systems in which a professional role evolves and from Damschroder et al’s (2009) framework for the implementation analysis. Methods This paper builds on a qualitative case study on the factors affecting the action plan’s implementation process that also revealed rich data about anticipated barriers to reaching outcomes. Data were collected through training sessions, field observations, documents, focus groups (n=20), and semistructured interviews (n=11) with stakeholders pertaining to the three systems under study. Content analysis was used to identify themes related to barriers. Results Seven barriers that may compromise the achievement of desired results were found. They relate to the legal framework, social representations, and media support in the sociocultural system and the practice environment, networks and communication mechanisms, and characteristics related to the role and the readiness in the professional system. Conclusion Disregarding sociocultural and professional system level, barriers may impede efforts to strengthen the midwife’s role and to provide qualified midwives who can improve the quality of maternal care. Making changes in the educational system cannot be thought of as an isolated process. Its success is closely tied with multiple contextual factors pertaining to the two other systems. Activities recommended to address these barriers may have great potential to build a competent midwifery workforce that contributes to positive maternal and neonatal health outcomes. PMID:26445547

    Rhythm control for atrial fibrillation (AF) is cumbersome because of its progressive nature caused by structural remodelling. Upstream therapy refers to therapeutic interventions aiming to modify the atrial substrate, leading to prevention of AF. The Routine versus Aggressive upstream rhythm Control for prevention of Early AF in heart failure (RACE 3) study hypothesises that aggressive upstream rhythm control increases persistence of sinus rhythm compared with conventional rhythm control in patients with early AF and mild-to-moderate early systolic or diastolic heart failure undergoing electrical cardioversion. RACE 3 is a prospective, randomised, open, multinational, multicenter trial. Upstream rhythm control consists of angiotensin converting enzyme inhibitors and/or angiotensin receptor blockers, mineralocorticoid receptor antagonists, statins, cardiac rehabilitation therapy, and intensive counselling on dietary restrictions, exercise maintenance, and drug adherence. Conventional rhythm control consists of routine rhythm control therapy without cardiac rehabilitation therapy and intensive counselling. In both arms, every effort is made to keep patients in the rhythm control strategy, and ion channel antiarrhythmic drugs or pulmonary vein ablation may be instituted if AF relapses. Total inclusion will be 250 patients. If upstream therapy proves to be effective in improving maintenance of sinus rhythm, it could become a new approach to rhythm control supporting conventional pharmacological and non-pharmacological rhythm control.

    Providing e-learning modules can be an effective strategy for enhancing gatekeepers' knowledge, self-confidence and skills in adolescent suicide prevention. The aim of this study was to test the effectiveness of an online training program called Mental Health Online which consists of eight short e-learning modules, each capturing an important aspect of the process of recognition, guidance and referral of suicidal adolescents (12-20 years). The primary outcomes of this study are participant's ratings on perceived knowledge, perceived self-confidence, and actual knowledge regarding adolescent suicidality. A randomized controlled trial will be carried out among 154 gatekeepers. After completing the first assessment (pre-test), participants will be randomly assigned to either the experimental group or the waitlist control group. One week after completing the first assessment the experimental group will have access to the website Mental Health Online containing the eight e-learning modules and additional information on adolescent suicide prevention. Participants in both conditions will be assessed 4 weeks after completing the first assessment (post-test), and 12 weeks after completing the post-test (follow-up). At post-test, participants from the experimental group are asked to complete an evaluation questionnaire on the modules. The waitlist control group will have access to the modules and additional information on the website after completing the follow-up assessment. Gatekeepers can benefit from e-learning modules on adolescent suicide prevention. This approach allows them to learn about this sensitive subject at their own pace and from any given location, as long as they have access to the Internet. Given the flexible nature of the program, each participant can compose his/her own training creating an instant customized course with the required steps in adolescent suicide prevention.

    Methylation of inorganic Hg in aquatic systems is a key process in the environmental cycling of this metal, not yet studied in tropical conditions. Radiochemical techniques were adapted and simplified, aiming at the study of Hg volatilization and methylation in water and sediment of gold mining areas in the Amazon region. Preliminary experiments showed, in 35 days volatilization of up to 32 % of 203 Hg 2+ added to aqueous solutions. Acid K 2 Cr 2 0 7 0.1 M solutions were not effective in 203 Hg 0 trapping and the latter was highly and irreversibly absorbed by a variety of synthetic materials commonly used in laboratory work. Considerably simplified versions of the Furutani and Rudd (1980) radiochemical technique for the determination of methylation rates in environmental samples were developed and showed efficiencies close to 90 % in tests with methyl- 2 0 3 H g standards. In-situ incubations of surface sediments were performed in the Madeira River gold mining region, Rondonia State, Brazil, and potential net Hg methylation rates (MR) of up to 1 %.g-1.h-1 were found in black-water affluent like the Mutum-Parana and Jamari rivers and in the Samuel reservoir. MRs in the Madeira River sediments were lower, ranging 10-5 to 10-3 %.g-1.h-1 . MRs obtained in incubations of samples some weeks after collection were one or two orders of magnitude lower than those resulting from in-situ incubations. Methylation in autoclaved samples was close to minimum detectable rates. MRs in surface water samples was in all cases < 7.10-7 %.ml-1.h-1. The determination of the predominant methylation sites will allow a better standardization of the technique described herein, suitable for MR determinations even under the unfavorable conditions prevailing in the Amazon region.

    Enhanced Recovery After Surgery (ERAS) programmes aim at an early recovery after surgical trauma and consequently at a reduced length of hospitalisation. This paper presents the protocol for a study that focuses on large-scale implementation of the ERAS programme in major gynaecological surgery in the Netherlands. The trial will evaluate effectiveness and costs of a stepped implementation approach that is characterised by tailoring the intensity of implementation activities to the needs of organisations and local barriers for change, in comparison with the generic breakthrough strategy that is usually applied in large-scale improvement projects in the Netherlands. All Dutch hospitals authorised to perform major abdominal surgery in gynaecological oncology patients are eligible for inclusion in this cluster randomised controlled trial. The hospitals that already fully implemented the ERAS programme in their local perioperative management or those who predominantly admit gynaecological surgery patients to an external hospital replacement care facility will be excluded. Cluster randomisation will be applied at the hospital level and will be stratified based on tertiary status. Hospitals will be randomly assigned to the stepped implementation strategy or the breakthrough strategy. The control group will receive the traditional breakthrough strategy with three educational sessions and the use of plan-do-study-act cycles for planning and executing local improvement activities. The intervention group will receive an innovative stepped strategy comprising four levels of intensity of support. Implementation starts with generic low-cost activities and may build up to the highest level of tailored and labour-intensive activities. The decision for a stepwise increase in intensive support will be based on the success of implementation so far. Both implementation strategies will be completed within 1 year and evaluated on effect, process, and cost-effectiveness. The primary

    Previous studies have reported on the promising effects of changing running style in patients with chronic exertional compartment syndrome (CECS) using a 6-week training program aimed at adopting a forefoot strike technique. This study expands that work by comparing a 6-week in-house, center-based run training program with a less extensive, supervised, home-based run training program (50% home training). An alteration in running technique will lead to improvements in CECS complaints and running performance, with the less supervised program producing less dramatic results. Cohort study; Level of evidence, 3. Nineteen patients with CECS were prospectively enrolled. Postrunning intracompartmental pressure (ICP), run performance, and self-reported questionnaires were taken for all patients at baseline and after 6 weeks of running intervention. Questionnaires were also taken from 14 patients (7 center-based, 6 home-based) 4 months posttreatment. Significant improvement between preintervention and postintervention rates was found for running distance (43%), ICP values (36%), and scores on the questionnaires Single Assessment Numeric Evaluation (SANE; 36%), Lower Leg Outcome Survey (LLOS; 18%), and Patient Specific Complaints (PSC; 60%). The mean posttreatment score on the Global Rating of Change (GROC) was between +4 and +5 ("somewhat better" to "moderately better"). In 14 participants (74%), no elevation of pain was reported posttreatment, compared with 3 participants (16%) at baseline; in all these cases, the running test was aborted because of a lack of cardiorespiratory fitness. Self-reported scores continued to improve 4 months after the end of the intervention program, with mean improvement rates of 48% (SANE), 26% (LLOS), and 81% (PSC). The mean GROC score improved to +6 points ("a great deal better"). In 19 patients diagnosed with CECS, a 6-week forefoot running intervention performed in both a center-based and home-based training setting led to decreased

    Although PCB has been forbidden for more than 20 years now, and its levels in human milk is declining, it remains among the chemicals in human milk causing most concern with regard to its possible detrimental effects on the fetus and the breastfed child. Due to our industry, amongst others, the Norwegian population has been rather heavily exposed to PCB. Furthermore, new environmental toxicants are steadily entering the scene, such as the Brominated flame retardants. The level of Brominated flame retardants in human milk has shown an exponential increase during the last ten years, and this group of chemicals, are causing increasingly more concern. Studies from Sweden has shown that the levels differ greatly between individuals, however, for reasons yet unknown. In Norway, the highest levels of Brominated flame retardants ever measured in the world was reported from fish in Mjoesa. Surprisingly few attempts has been made to identify dietary habits or other life style factors that are associated with the levels of these toxicants in human milk. Such knowledge is needed in order for accurate prophylactic measures to be taken by the population and of special importance to women before and during child bearing age, in order to keep the levels in human milk as low as possible. Furthermore, there is great need for more knowledge of the effects of these toxicants on child health. The need for more research in this field, especially the need for prospective exposure data and the need for interdisciplinary approaches has been specifically targeted. Therefore a research initiative was taken in Norway to establish a prospective birth cohort which aims to recruit 6000 mother/child pairs, in whom human milk samples are collected in infancy and information on health outcomes are collected throughout the child's first seven years of life. The aim of this presentation is to describe this project in more detail and to give some preliminary results.

    What are motivations of owners of an advance directive (AD) to draft an AD, what do they aim for with their AD and do they communicate about their AD? Written questionnaires were sent to a cohort of people owning different types of ADs (n=5768). A purposive sample of people suffering from an illness was selected from the cohort for an in-depth interview (n=29). About half of our population had no direct motivation to draft their AD. Most mentioned motivation for the other half was an illness of a family member or friend. Many different and specific aims for drafting an AD were mentioned. An often mentioned more general aim in people with different ADs was to prevent unnecessary lengthening of life or treatment (14-16%). Most respondents communicated about having an AD with close-ones (63-88%) and with their GP (65-79%). In the interviews people gave vivid examples of experiences of what they hoped to prevent at the end of life. Some mentioned difficulties foreseeing the future and gave examples of response shift. ADs can give directions to caregivers about what people want at the end of life. ADs have to be discussed in detail by their owners and caregivers, since owners often have specific aims with their AD. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    We investigated brain activity in elite, expert, and novice archers during a simulated archery aiming task to determine whether neural correlates of performance differ by skill level. Success in shooting sports depends on complex mental routines just before the shot, when the brain prepares to execute the movement. During functional magnetic resonance imaging, 40 elite, expert, or novice archers aimed at a simulated 70-meter-distant target and pushed a button when they mentally released the bowstring. At the moment of optimal aiming, the elite and expert archers relied primarily on a dorsal pathway, with greatest activity in the occipital lobe, temporoparietal lobe, and dorsolateral pre-motor cortex. The elites showed activity in the supplementary motor area, temporoparietal area, and cerebellar dentate, while the experts showed activity only in the superior frontal area. The novices showed concurrent activity in not only the dorsolateral pre-motor cortex but also the ventral pathways linked to the ventrolateral pre-motor cortex. The novices exhibited broad activity in the superior frontal area, inferior frontal area, ventral prefrontal cortex, primary motor cortex, superior parietal lobule, and primary somatosensory cortex. The more localized neural activity of elite and expert archers than novices permits greater efficiency in the complex processes subserved by these regions. The elite group's high activity in the cerebellar dentate indicates that the cerebellum is involved in automating simultaneous movements by integrating the sensorimotor memory enabled by greater expertise in self-paced aiming tasks. A companion article comments on and generalizes our findings.

    2012-12-01

    This article reports a pilot study of a new smoking cessation website ('StopAdvisor'), which has been developed on the basis of PRIME theory, evidence, web-design expertise and user-testing. The aims were to i) evaluate whether cessation, website usage and satisfaction were sufficiently high to warrant a randomised controlled trial (RCT) and ii) assess whether outcomes were affected by socio-economic status. This was an uncontrolled pilot study. Two hundred and four adult daily smokers willing to make a serious quit attempt were included. All participants received support from 'StopAdvisor', which recommends a structured quit plan and a variety of evidence-based behaviour change techniques for smoking cessation. A series of tunnelled sessions and a variety of interactive menus provide tailored support for up to a month before quitting through until one-month post-quit (http://www.lifeguideonline.org/player/play/stopadvisordemonstration). The primary outcome was self-report of at least 1month of continuous abstinence collected at 2months post-enrolment and verified by saliva cotinine or anabasine. Usage was indexed by log-ins and page views. Satisfaction was assessed by dichotomous ratings of helpfulness, personal relevance, likelihood of recommendation and future use, which were collected using an online questionnaire at 2months post-enrolment. Outcomes according to socio-economic status were assessed. At 8weeks post-enrolment, 19.6% (40/204) of participants were abstinent according to the primary outcome criteria (95% C.I.=14.1% to 25.1%). Participants viewed a mean of 133.5 pages (median=71.5) during 6.4 log-ins (median=3). A majority of respondents rated the website positively on each of the four satisfaction `ratings (range=66.7% to 75.3%). There was no evidence of an effect of socio-economic status on abstinence (OR=1.01, C.I.=0.50-2.07), usage (page-views, t(202)=0.11, p=.91; log-ins, t(202)=0.21, p=.83), or satisfaction (helpfulness, OR=1.09, C.I.=0

    Context • Prayer healing is a common practice in many religious communities around the world. Even in the highly secularized Dutch society, cases of prayer healing are occasionally reported in the media, often generating public attention. There is an ongoing debate regarding whether such miraculous cures do actually occur and how to interpret them. Objective • The aim of the article was to present a research protocol for the investigation of reported cases of remarkable and/or unexplained healing after prayer. Design • The research team developed a method to perform a retrospective, case-based study of prayer healing. Reported prayer healings can be investigated systematically in accordance with a step-by-step methodology. The focus is on understanding the healing by studying it from multiple perspectives, using both medical judgment and patients' narratives collected by qualitative methods Setting • The study occurred at Vrije Universiteit (VU) and VU Medical Center (Amsterdam, Netherlands) as well as the general medical practice of the first author. Participants • Potential participants could be any individuals in the Netherlands or neighboring countries who claim to have been healed through prayer. The reports of healing came from multiple sources, including the research team's medical practices and their direct vicinities, newspaper articles, prayer healers, and medical colleagues. Outcome Measures • Medical data were obtained before and after prayer. Subsequently, a member of a research team and of a medical assessment committee made a standardized judgment that evaluated whether a cure was clinically remarkable or scientifically unexplained. The participants' experiences and insider perspectives were studied, using in-depth interviews in accordance with a qualitative research methodology, to gain insight into the perceptions and explanations of the cures that were offered by participants and by the members of the medical assessment committee.

  11. The diverse aims of science.

    There is increasing attention to the centrality of idealization in science. One common view is that models and other idealized representations are important to science, but that they fall short in one or more ways. On this view, there must be an intermediary step between idealized representation and the traditional aims of science, including truth, explanation, and prediction. Here I develop an alternative interpretation of the relationship between idealized representation and the aims of science. I suggest that continuing, widespread idealization calls into question the idea that science aims for truth. If instead science aims to produce understanding, this would enable idealizations to directly contribute to science's epistemic success. I also use the fact of widespread idealization to motivate the idea that science's wide variety aims, epistemic and non-epistemic, are best served by different kinds of scientific products. Finally, I show how these diverse aims—most rather distant from truth—result in the expanded influence of social values on science. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Neurofeedback is a nonpharmacological treatment for attention-deficit hyperactivity disorder (ADHD). We propose that operant conditioning of electroencephalogram (EEG) in neurofeedback training aimed to mitigate inattention and low arousal in ADHD, will be accompanied by changes in EEG bands' relative power. Patients were 18 children diagnosed with ADHD. The neurofeedback protocol ("Focus/Alertness" by Peak Achievement Trainer) has a focused attention and alertness training mode. The neurofeedback protocol provides one for Focus and one for Alertness. This does not allow for collecting information regarding changes in specific EEG bands (delta, theta, alpha, low and high beta, and gamma) power within the 2 to 45 Hz range. Quantitative EEG analysis was completed on each of twelve 25-minute-long sessions using a custom-made MatLab application to determine the relative power of each of the aforementioned EEG bands throughout each session, and from the first session to the last session. Additional statistical analysis determined significant changes in relative power within sessions (from minute 1 to minute 25) and between sessions (from session 1 to session 12). Analysis was of relative power of theta, alpha, low and high beta, theta/alpha, theta/beta, and theta/low beta and theta/high beta ratios. Additional secondary measures of patients' post-neurofeedback outcomes were assessed, using an audiovisual selective attention test (IVA + Plus) and behavioral evaluation scores from the Aberrant Behavior Checklist. Analysis of data computed in the MatLab application, determined that theta/low beta and theta/alpha ratios decreased significantly from session 1 to session 12, and from minute 1 to minute 25 within sessions. The findings regarding EEG changes resulting from brain wave self-regulation training, along with behavioral evaluations, will help elucidate neural mechanisms of neurofeedback aimed to improve focused attention and alertness in ADHD.

    This paper attempts to consider the aims that undergraduate physics degree courses actually reflect and serve in the light of the employment patterns of graduates and of the expressed needs of employers. Calling on evidence mainly from the UK, it reviews analyses of what degree examinations actually test, and goes on to quote criticisms of their courses and radical proposals to change them adopted by the senior physics professors in the UK. The discussion is then broadened by discussion of evidence, about the employment of graduates and about the priorities that some industrialists now give in the qualities that they look for when recruiting new graduates. The evidence leads to a view that radical changes are needed, both in courses and examinations, and that there is a need for university departments to work more closely with employers in re-formulating the aims and priorities in their teaching.

    With the aim of developing new functional foods, a traditional product, the table olive, was used as a vehicle for incorporating probiotic bacterial species. Survival on table olives of Lactobacillus rhamnosus (three strains), Lactobacillus paracasei (two strains), Bifidobacterium bifidum (one strain), and Bifidobacterium longum (one strain) at room temperature was investigated. The results obtained using a selected olive sample demonstrated that bifidobacteria and one strain of L. rhamnosus (Lactobacillus GG) showed a good survival rate, with a recovery of about 10(6) CFU g(-1) after 30 days. The Lactobacillus GG population remained unvaried until the end of the experiment, while a slight decline (to about 10(5) CFU g(-1)) was observed for bifidobacteria. High viability, with more than 10(7) CFU g(-1), was observed throughout the 3-month experiment for L. paracasei IMPC2.1. This strain, selected for its potential probiotic characteristics and for its lengthy survival on olives, was used to validate table olives as a carrier for transporting bacterial cells into the human gastrointestinal tract. L. paracasei IMPC2.1 was recovered from fecal samples in four out of five volunteers fed 10 to 15 olives per day carrying about 10(9) to 10(10) viable cells for 10 days.

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

    Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by deficits in cognitive and emotional self-control. Optical technique acquisitions, such as near infrared spectroscopy (NIRS), seem to be very promising during developmental ages, as they are non- invasive techniques and less influenced by body movements than other neuroimaging methods. Recently, these new techniques are being widely used to measure neural correlates underlying neuropsychological deficits in children with ADHD. In a short series of articles, we will review the results of functional NIRS (fNIRS) studies in children with ADHD. The present brief review will focus on the results of the fNIRS studies that investigate cortical activity during neuropsychological and/or emotional tasks. According to the reviewed studies, children and adolescents with ADHD show peculiar cortical activation both during neurological and emotional tasks, and the majority of the reviewed studies revealed lower prefrontal cortex activation in patients compared to typically developmental controls. a consistent interpretation of these results is limited by the substantial methodological heterogeneity including patients' medication status and washout period, explored cerebral regions, neuropsychological tasks, number of channels and sampling temporal resolutions. fNIRS seems to be a promising tool for investigating neural substrates of emotional dysregulation and executive function deficits in individuals with ADHD during developmental ages.

    2016-07-01

    Qualitative methodology is extensively used in a wide range of scientific areas, such as Sociology and Psychology, and it is been used to study individual and household decision making processes. However, in the Transportation Planning and Engineering domain it is still infrequent to find in the travel behavior literature studies using qualitative techniques to explore activity-travel decisions. The aim of this paper is first, to provide an overview of the types of qualitative techniques available and to explore how to correctly implement them. Secondly, to highlight the special characteristics of qualitative methods that make them appropriate to study activity-travel decision processes. Far from been an unempirical or intuitive methodology, using qualitative methods properly implies a strong foundation on theoretical frameworks, a careful design of data collection and a deep data analysis. For such a purpose, a review of the scarce activity-travel behavior literature using qualitative methods, or a combination of qualitative and quantitative approaches, is presented. The use of qualitative techniques can play a role of being a supplementary way of obtaining information related to activity-travel decisions which otherwise it would be extremely difficult to find. This work ends with some conclusions about how qualitative research could help in making progress on activity-travel behavior studies. (Author)

    . Although not flawless, and often criticized for a variety of reasons, citation analysis is a commonly used technique in this field, is a frequent means to ''weight'' the scientific production of researchers and is one of the criteria used to assign research grants. Our study shows that European radiology is growing and its production is increasing over time, thus indicating strong commitment to research from European radiologists; however, European radiological research has not yet reached leadership in the literature, and mean indexes addressing the level of resources allocated to research are lower in Europe than in the U.S. This latter point has notable exceptions, but indicates inadequacy of funding, at least in some nations, and in Europe as a whole. The development of research programs within the framework of the European Union specifically aimed to radiology could lead to further advancement of our discipline. (orig.)

    2014-11-01

    Full Text Available This paper addresses to accounting researchers and proposes the use of abductive research strategy to improve the quality of accounting research outcomes. We argue that abductive reasoning has developed as a typical research method in all fields of interpretive studies but is still unrecognized by accounting researchers and practitioners. Therefore, this study aims to raise awareness on the benefits obtained through the implementation of abduction as a research strategy. Starting from Peirce (1903 and Blaikie (1993, we explore two types of abduction designs and discuss the advantages of building accounting research on grounded concepts. While this is a conceptual paper that only describes the bridge abduction reasoning can build between studying the reality and new theory emergence, we do not tackle any ethnographical case studies, social survey, or other exploratory field analyses.

  7. Accelerator research studies. Progress report

    International Nuclear Information System (INIS)

    1983-07-01

    The major goal of this project is to study the effects that lead to emittance growth and limitation of beam current and brightness in periodic focusing systems (including linear accelerators). This problem is of great importance for all accelerator applications requiring high intensity beams with small emittance such as heavy ion fusion, spallation neutron sources and high energy physics. In the latter case, future machines must not only provide higher energies (in the range of 10 to 100 TeV), but also higher luminosities than the existing facilities. This implies considerably higher phase-space density of the particle beam produced by the injector linac, i.e., the detrimental emittance growth and concurrent beam loss observed in existing linacs must be avoided

    The execution of functions such as contingency analysis, optimization, reactive dispatch, etc, at the control centers requires appropriate models representing the non-observable parts (external system). The classical external equivalents have been developed considering basically the contingency analysis. This work points out the performance of the Extended Ward Equivalent (W.E.), which currently represents the state of art concerning reduced circuit based models. the work analyzes the W.E. response to changes occurred in optimization studied. Moreover, a new model, named INTERNAL REACTIVE WARD (WRINT), resulting from an adaptation of the W.E. is proposed focusing on the improvement of the equivalent in case of changes occurs in optimization studies. The model's general idea is to reflect the equivalent's capacity of reactive response into the internal system. Comparative computational test results are shown. The details of routines implementation are also pointed out. (author)

    Nepal is on track to achieve MDG 5 but there is a huge sub-national disparity with existing high maternal mortality in western and hilly regions. The national priority is to reduce this disparity to achieve the goal at sub-national level. Evidences from developing countries show that increasing utilization of skilled attendant at birth is an important indicator for reducing maternal death. Further, there is a very low utilization during childbirth in western and hilly regions of Nepal which clearly depicts the barriers in utilization of skilled birth attendants. So, there is a need to overcome the identified barriers to increase the utilization thereby decreasing the maternal mortality. The hypothesis of this study is that through a package of interventions the utilization of skilled birth attendants will be increased and hence improve maternal health in Nepal. This study involves a cluster randomized controlled trial involving approximately 5000 pregnant women in 36 clusters. The 18 intervention clusters will receive the following interventions: i) mobilization of family support for pregnant women to reach the health facility, ii) availability of emergency funds for institutional childbirth, iii) availability of transport options to reach a health facility for childbirth, iv) training to health workers on communication skills, v) security provisions for SBAs to reach services 24/24 through community mobilization; 18 control clusters will not receive the intervention package. The final evaluation of the intervention is planned to be completed by October 2014. Primary study output of this study is utilization of SBA services.

    As the single photon emission computed tomography (SPECT) image has rather big between-facility and -machine differences, a questionnaire was done to 18 SPECT facilities in Aomori Prefecture in May, 03, 15 of which answered, for the purpose of standardization of the brain blood flow images in the prefecture. The questionnaire concerned the condition of data collection, image display and reconstruction, and quantitative analysis, based on whose results the Phantom Study was then conducted to see the relationship between the average count and Butterworth filter (BWF) cut-off value by comparison of reference and facilities' images. The gamma camera PRISM 200XP, processor Odyssey Fx and low-energy high-resolution (LEHR) collimator were used for the reference image with collection matrix 128 x 128, 3.5 mm pixel size, Ramp reconstruction filter, Chang decay correction (coefficient μ=0.09) and null scattering correction. Used was the Hoffman phantom containing 30-37 MBq of 99m Tc or 8-18 MBq of 123 I. It was found that the fluctuation of cut-off values became small depending on the increase of count and the collection count was low for both nuclides in those facilities, and thus further study of the measure for increasing the collection count was thought necessary.

    This study is performed and partially funded within the framework of the European Communities (R and D-programme on Management and Disposal of Radioactive Waste). The purpose of this study is to work out an information strategy on radioactive waste management for a selected target public (15-to-18 year old youngsters), with a view to raising public opinion and achieving a better understanding of this matter. The choice of this target public has been inspired among others by the importance of the youngsters as future opinion leaders. The results of an opinion poll, conducted in the autumn of 1991, were used to define the scope of the project and to determine the communication model and plan that will serve as a basis for the further development of the project. The first steps were taken to develop a pedagogical package, the structure, form and content of which have been determined. Preparations were also made to define the concept and the content of an information centre tuned to the pedagogical package and, like the other information, intended to inform 15-to-18 year old students.

    2007-11-01

    The paper is a report of a study to demonstrate how the use of schematics can provide procedural clarity and promote rigour in the conduct of case study research. Case study research is a methodologically flexible approach to research design that focuses on a particular case - whether an individual, a collective or a phenomenon of interest. It is known as the 'study of the particular' for its thorough investigation of particular, real-life situations and is gaining increased attention in nursing and social research. However, the methodological flexibility it offers can leave the novice researcher uncertain of suitable procedural steps required to ensure methodological rigour. This article provides a real example of a case study research design that utilizes schematic representation drawn from a doctoral study of the integration of health promotion principles and practices into a palliative care organization. The issues discussed are: (1) the definition and application of case study research design; (2) the application of schematics in research; (3) the procedural steps and their contribution to the maintenance of rigour; and (4) the benefits and risks of schematics in case study research. The inclusion of visual representations of design with accompanying explanatory text is recommended in reporting case study research methods.

    Full Text Available Abstract Background Up to 42% of all stroke patients do not get out of the house as much as they would like. This can impede a person’s quality of life. This study is testing the clinical effectiveness and cost effectiveness of a new outdoor mobility rehabilitation intervention by comparing it to usual care. Methods/design This is a multi-centre parallel group individually randomised, controlled trial. At least 506 participants will be recruited through 15 primary and secondary care settings and will be eligible if they are over 18 years of age, have had a stroke and wish to get out of the house more often. Participants are being randomly allocated to either the intervention group or the control group. Intervention group participants receive up to 12 rehabilitation outdoor mobility sessions over up to four months. The main component of the intervention is repeated practice of outdoor mobility with a therapist. Control group participants are receiving the usual intervention for outdoor mobility limitations: verbal advice and provision of leaflets provided over one session. Outcome measures are being collected using postal questionnaires, travel calendars and by independent assessors. The primary outcome measure is the Social Function domain of the SF36v2 quality of life assessment six months after recruitment. The secondary outcome measures include: functional ability, mobility, the number of journeys (monthly travel diaries, satisfaction with outdoor mobility, mood, health-related quality of life, resource use of health and social care. Carer mood information is also being collected. The mean Social Function score of the SF-36v2 will be compared between treatment arms using a multiple membership form of mixed effects multiple regression analysis adjusting for centre (as a fixed effect, age and baseline Social Function score as covariates and therapist as a multiple membership random effect.

    The purpose of this article was to test whether physical activity, healthy eating, and emotional well-being would improve if patients received feedback about biomarkers that have been shown to be responsive to changes in weight and fitness. Patients were randomized to limited feedback (weight, body mass index [BMI], and blood pressure at 4 and 10 months) or enhanced feedback (weight, BMI, blood pressure, homeostatic insulin resistance, and nuclear magnetic resonance lipoprotein profiles at 2, 4, 7, and 10 months). Repeated measures mixed effects multivariate regression models were used to determine whether BMI, fitness, diet, and quality of life changed over time. Major parameters were similar in both groups at baseline. BMI, measures of fitness, healthy eating, quality of life, and health state improved in both patient groups, but there was no difference between patient groups at 4 or 10 months. Systolic blood pressure improved in the enhanced feedback group, and there was a difference between the enhanced and limited feedback groups at 10 months (95% confidence interval, -6.011 to -0.5113). Providing patients with enhanced feedback did not dramatically change outcomes. However, across groups, many patients maintained or lost weight, suggesting the need for more study of nondiet interventions.

  1. Competitive service centers location in the cities with aim to reduce traffic (Case study: Health centers location in the city if Isfahan

    Full Text Available Abstract   Distribution of goods and services in cities is of utmost importance. Selecting appropriate venues for different service centers in a city not only enables the citizens to access these services much more easily, but also reduces the traffic load caused by trips made to reach them. Unfortunately, the lack of a correct urban planning has led to inappropriate formation of many cities around the world in terms of the locations assumed for different service centers. Since the private sector has been given the responsibility to construct most of these centers, changing their current locations may be restricted due to legal obligations. Therefore, it seems necessary for the government to construct new service centers with high competitive facilities to attract customers and to compete with those built by the private sector. In this paper, the selection of appropriate locations to construct new service centers has been studied. Such locations have been selected in a way to fulfill goals such as rapid and easy accessibility for the customers and reduction of traffic drawbacks caused by the related trips. In this regard, a model for service centers with restricted capacity has been designed and a parallel simulated annealing algorithm has been proposed to solve it. Finally, the proposed algorithm has been utilized to locate the health centers around the city of Isfahan and its efficiency has been investigated. The findings highlight the accuracy and speed of the proposed algorithm in location of the health centers of Isfahan.

    There is little empirical evidence of the impact of transition from primary to secondary school on obesity-related risk behaviour. The purpose of this study was to examine the effect of a change of school system on physical activity (PA) and sedentary behaviour in pre-early adolescents. Fifteen schools in Victoria, Australia were recruited at random from the bottom two strata of a five level socio-economic scale. In nine schools, students in year 6 primary school transitioned to a different school for year 7 secondary school, while in six schools (combined primary-secondary), students remained in the same school environment from year 6 to year 7. Time 1 (T1) measures were collected from students (N=245) in year 6 (age 11-13). Time 2 (T2) data were collected from 243 (99%) of the original student cohort when in year 7. PA and sedentary behaviour data were collected objectively (via ActiGraph accelerometer) and subjectively (via child self-report recall questionnaire). School environment data were collected via school staff survey. Change of behaviour analyses were conducted longitudinally i) for all students and ii) by change/no change of school. Mixed model regression analysis tested for behavioural interaction effects of changing/not changing school. Sixty-three percent (N=152) changed schools from T1 to T2. Across all students we observed declines in average daily moderate to vigorous physical activity (MVPA) (-4 min) and light PA (-23 min), and increases in average daily sedentary behaviour (16 min), weekday leisure screen time (17 min) and weekday homework screen time (25 min), all Penvironment, students who changed school reported a greater reduction in PA intensity at recess and lunch, less likelihood to cycle to/from school, greater increase in weekday (41 mins) and weekend (45 mins) leisure screen time (Pbehaviour, and has further compounding effects on behaviour type by changing school environments.

    2016-07-01

    Research problem selection is central to the dynamics of scientific knowledge production. Research agendas result from the selection of research problems and the formulation of individual and/or collective academic strategies to address them. But, why researchers study what they study? This paper presents incipient research focused on the way different factors influence the construction of academic research agendas. It takes a researcher-oriented approach relying on opinions and perspectives of a wide range of researchers in all fields of knowledge. The empirical work is carried out in Uruguay, a country in the periphery of mainstream science, whose academic community struggles in search of a balance between the requirements of the world community of scholars and the demands from different national stakeholders. The methodology and research results from this study may be relevant to other countries, at different peripheries. Further, understanding the interplay of influences that shape research agendas is an important tool for policy analysis and planning everywhere. (Author)

    This research paper gives an account of a study into the relationship between leadership and integrity. There is a critical analysis of the current literature for effective, successful and ethical leadership particularly, integrity. The purpose and aim of this paper is to build on the current notions of leadership within the literature, debate contemporary approaches, focussing specifically on practices within the UK National Health Service in the early 21st century. This leads to a discussion of the literature on ethical leadership theory, which includes public service values, ethical relationships and leading with integrity. A small study was undertaken consisting of 18 interviews with leaders and managers within a District General HospitaL Using the Repertory Grid technique and analysis 15 themes emerged from the constructs elicited, which were compared to the literature for leadership and integrity and other studies. As well as finding areas of overlap, a number of additional constructs were elicited which suggested that effective leadership correlates with integrity and the presence of integrity will improve organisational effectiveness. The study identified that perceptions of leadership character and behaviour are used to judge the effectiveness and integrity of a leader. However, the ethical implications and consequences of leaders' scope of power and influence such as policy and strategy are somewhat neglected and lacking in debate. The findings suggest that leaders are not judged according to the ethical nature of decision making, and leading and managing complex change but that the importance of integrity and ethical leadership correlated with higher levels of hierarchical status and that it is assumed by virtue of status and success that leaders lead with integrity. Finally, the findings of this study seem to suggest that nurse leadership capability is developing as a consequence of recent national investment.

    2017-08-01

    Objectives: The primary goal of this review is to summarize significant developments in the field of Clinical Research Informatics (CRI) over the years 2015-2016. The secondary goal is to contribute to a deeper understanding of CRI as a field, through the development of a strategy for searching and classifying CRI publications. Methods: A search strategy was developed to query the PubMed database, using medical subject headings to both select and exclude articles, and filtering publications by date and other characteristics. A manual review classified publications using stages in the "research study lifecycle", with key stages that include study definition, participant enrollment, data management, data analysis, and results dissemination. Results: The search strategy generated 510 publications. The manual classification identified 125 publications as relevant to CRI, which were classified into seven different stages of the research lifecycle, and one additional class that pertained to multiple stages, referring to general infrastructure or standards. Important cross-cutting themes included new applications of electronic media (Internet, social media, mobile devices), standardization of data and procedures, and increased automation through the use of data mining and big data methods. Conclusions: The review revealed increased interest and support for CRI in large-scale projects across institutions, regionally, nationally, and internationally. A search strategy based on medical subject headings can find many relevant papers, but a large number of non-relevant papers need to be detected using text words which pertain to closely related fields such as computational statistics and clinical informatics. The research lifecycle was useful as a classification scheme by highlighting the relevance to the users of clinical research informatics solutions. Georg Thieme Verlag KG Stuttgart.

    Gibson, Barbara E; Stasiulis, Elaine; Gutfreund, Shawna; McDonald, Maria; Dade, Lauren

    2011-08-01

    In Canadian jurisdictions without specific legislation pertaining to research consent, the onus is placed on researchers to determine whether a child is capable of independently consenting to participate in a research study. Little, however, is known about how child health researchers are approaching consent and capacity assessment in practice. The aim of this study was to explore and describe researchers' current practices. The study used a qualitative descriptive design consisting of 14 face-to-face interviews with child health researchers and research assistants in Southern Ontario. Transcribed interviews were analysed for common themes. Procedures for assessing capacity varied considerably from the use of age cutoffs to in-depth engagement with each child. Three key issues emerged from the accounts: (1) requirements that consent be provided by a single person thwarted researchers' abilities to support family decision-making; (2) little practical distinction was made between assessing if a child was capable, versus determining if study information had been adequately explained by the researcher; and (3) participants' perceived that review boards' requirements may conflict with what they considered ethical consent practices. The results suggest that researchers' consent and capacity knowledge and skills vary considerably. Perceived discrepancies between ethical practice and ethics boards' requirements suggest the need for dialogue, education and possibly ethics board reforms. Furthermore we propose, where appropriate, a 'family decision-making' model that allows parents and their children to consent together, thereby shifting the focus from separate assent and consent procedures to approaches that appropriately engage the child and family.

    Background E-Delphi is a way to access a geographically dispersed group of experts. It is similar to other Delphi methods but conducted online. E-research methodologies, such as the e-Delphi method, have yet to undergo significant critical discussion. Aim To highlight some of the challenges nurse researchers may wish to consider when using e-Delphi in their research. Discussion This paper provides details about the author's approach to conducting an e-Delphi study in which a group of health literacy nurse experts (n=41) used an online survey platform to identify and prioritise essential health literacy competencies for registered nurses. Conclusion This paper advances methodological discourse about e-Delphi by critically assessing an e-Delphi case study. The online survey platform used in this study was advantageous for the researcher and the experts: the experts could participate at any time and place where the internet was available; the researcher could efficiently access a national group of experts, track responses and analyse data in each round. Implications for practice E-Delphi studies create opportunities for nurse researchers to conduct research nationally and internationally. Before conducting an e-Delphi study, researchers should carefully consider the design and methods for collecting data, to avoid challenges that could potentially compromise the quality of the findings. Researchers are encouraged to publish details about their approaches to e-Delphi studies, to advance the state of the science.

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

    To provide examples of a qualitative multiple case study to illustrate the specific strategies that can be used to ensure the credibility, dependability, confirmability and transferability of a study. There is increasing recognition of the valuable contribution qualitative research can make to nursing knowledge. However, it is important that the research is conducted in a rigorous manner and that this is demonstrated in the final research report. A multiple case study that explored the role of the clinical skills laboratory in preparing students for the real world of practice. Multiple sources of evidence were collected: semi-structured interviews (n=58), non-participant observations at five sites and documentary sources. Strategies to ensure the rigour of this research were prolonged engagement and persistent observation, triangulation, peer debriefing, member checking, audit trail, reflexivity, and thick descriptions. Practical examples of how these strategies can be implemented are provided to guide researchers interested in conducting rigorous case study research. While the flexible nature of qualitative research should be embraced, strategies to ensure rigour must be in place.

    2002-01-01

    Poultry are not simply birds; they are also a human creation, a social and cultural practice. The human element is the justification for an anthropology of poultry. Such an anthropology combines the objective research strategies familiar to the natural sciences with what is often called 'subjective' or qualitative research. In the study of poultry management, it is important that both research strategies focus on differences and variation. The subjective approach is particularly useful in identifying and understanding how the motivations and strategies of local actors are dependent on the social positions, which they occupy in their specific societies.

    Deliberative ways of dealing with ethical issues in health care are expanding. Moral case deliberation is an example, providing group-wise, structured reflection on dilemmas from practice. Although moral case deliberation is well described in literature, aims and results of moral case deliberation sessions are unknown. This research shows (a) why managers introduce moral case deliberation and (b) what moral case deliberation participants experience as moral case deliberation results. A responsive evaluation was conducted, explicating moral case deliberation experiences by analysing aims (N = 78) and harvest (N = 255). A naturalistic data collection included interviews with managers and evaluation questionnaires of moral case deliberation participants (nurses). From the analysis, moral case deliberation appeals for cooperation, team bonding, critical attitude towards routines and nurses' empowerment. Differences are that managers aim to foster identity of the nursing profession, whereas nurses emphasize learning processes and understanding perspectives. We conclude that moral case deliberation influences team cooperation that cannot be controlled with traditional management tools, but requires time and dialogue. Exchanging aims and harvest between manager and team could result in co-creating (moral) practice in which improvements for daily cooperation result from bringing together perspectives of managers and team members.

    2014-01-01

    Full Text Available A review of literature indicates that there are different types of qualitative research methods such as action research, content analysis, ethnography, grounded theory, historical analysis, phenomenology and case study. However, which approach is to be used depends on several factors such as the nature and objectives of the research. The aim of this paper is to focus on the research methodology aspects of applying case study as a research approach and its relevance in tourism destination branding research specifically on a single case study (SCS context. There are arguments that the SCS is a weak research strategy. Some of the potentials or shortcomings highlighted in the literature include the primitive nature of SCS, flexibility of sample technique, data collection method and data analysis. Others include lack of rigour, reliability, validity, credibility of findings and generalisation. This paper has adopted content analysis of the literature on tourism destination branding. Findings indicate that the quality of SCS can be verified using specific case study tactics for four design tests such as validity (construct, internal and external; and reliability using the case study protocol. Theoretical implication suggests that SCS is an empirical enquiry use to understand complex phenomena and favoured by practitioners.

    In critically ill patients, acute respiratory distress syndrome (ARDS) and ventilator-associated conditions (VACs) are associated with increased mortality, survivor morbidity and healthcare resource utilisation. Studies conclusively demonstrate that initial ventilator settings in patients with ARDS, and at risk for it, impact outcome. No studies have been conducted in the emergency department (ED) to determine if lung-protective ventilation in patients at risk for ARDS can reduce its incidence. Since the ED is the entry point to the intensive care unit for hundreds of thousands of mechanically ventilated patients annually in the USA, this represents a knowledge gap in this arena. A lung-protective ventilation strategy was instituted in our ED in 2014. It aims to address the parameters in need of quality improvement, as demonstrated by our previous research: (1) prevention of volutrauma; (2) appropriate positive end-expiratory pressure setting; (3) prevention of hyperoxia; and (4) aspiration precautions. The lung-protective ventilation initiated in the emergency department (LOV-ED) trial is a single-centre, quasi-experimental before-after study testing the hypothesis that lung-protective ventilation, initiated in the ED, is associated with reduced pulmonary complications. An intervention cohort of 513 mechanically ventilated adult ED patients will be compared with over 1000 preintervention control patients. The primary outcome is a composite outcome of pulmonary complications after admission (ARDS and VACs). Multivariable logistic regression with propensity score adjustment will test the hypothesis that ED lung-protective ventilation decreases the incidence of pulmonary complications. Approval of the study was obtained prior to data collection on the first patient. As the study is a before-after observational study, examining the effect of treatment changes over time, it is being conducted with waiver of informed consent. This work will be disseminated by

    Conducting ethically grounded research is a fundamental facet of all investigations. Nevertheless, the administrative burdens of current ethics review are substantial, and calls have been made for a reduction in research waste. To describe the heterogeneity in administration and documentation required by Human Research Ethics Committees (HRECs) and Research Governance Offices (RGOs) across Australia. In establishing a nationwide study to investigate the molecular aetiology of Giant Cell Arteritis (GCA), for which archived pathological specimens from around Australia are being recruited, we identified variation across separate HREC and RGO requirements. Submission paperwork and correspondence from each collaborating site and its representative office for research were reviewed. This data was interrogated to evaluate differences in current guidelines. Twenty-five pathology departments across seven Australian States collaborated in this study. All states, except Victoria, employed a single ethics review model. There was discrepancy amongst HRECs as to which application process applied to our study: seven requested completion of a "National Ethics Application Form" and three a "Low Negligible Risk" form. Noticeable differences in guidelines included whether electronic submission was sufficient. There was variability in the total number of documents submitted (range five to 22) and panel review turnaround time (range nine to 136 days). We demonstrate the challenges and illustrate the heavy workload involved in receiving widespread ethics and governance approval across Australia. We highlight the need to simplify, homogenise, and nationalise human ethics for non-clinical trial studies. Reducing unnecessary administration will enable investigators to achieve research aims more efficiently.

    Directory of Open Access Journals (Sweden)

    Rita Sleimen-Malkoun

    Full Text Available The lawful continuous linear relation between movement time and task difficulty (i.e., index of difficulty; ID in a goal-directed rapid aiming task (Fitts' law has been recently challenged in reciprocal performance. Specifically, a discontinuity was observed at critical ID and was attributed to a transition between two distinct dynamic regimes that occurs with increasing difficulty. In the present paper, we show that such a discontinuity is also present in discrete aiming when ID is manipulated via target width (experiment 1 but not via target distance (experiment 2. Fitts' law's discontinuity appears, therefore, to be a suitable indicator of the underlying functional adaptations of the neuro-muscular-skeletal system to task properties/requirements, independently of reciprocal or discrete nature of the task. These findings open new perspectives to the study of dynamic regimes involved in discrete aiming and sensori-motor mechanisms underlying the speed-accuracy trade-off.

    Researchers sometimes undertake qualitative research with randomised controlled trials (RCTs) of health interventions. To systematically explore how qualitative research is being used with trials and identify ways of maximising its value to the trial aim of providing evidence of effectiveness of health interventions. A sequential mixed methods study with four components. (1) Database search of peer-reviewed journals between January 2008 and September 2010 for articles reporting the qualitative research undertaken with specific trials, (2) systematic search of database of registered trials to identify studies combining qualitative research and trials, (3) survey of 200 lead investigators of trials with no apparent qualitative research and (4) semistructured telephone interviews with 18 researchers purposively sampled from the first three methods. Qualitative research was undertaken with at least 12% of trials. A large number of articles reporting qualitative research undertaken with trials (n=296) were published between 2008 and 2010. A total of 28% (82/296) of articles reported qualitative research undertaken at the pre-trial stage and around one-quarter concerned drugs or devices. The articles focused on 22 aspects of the trial within five broad categories. Some focused on more than one aspect of the trial, totalling 356 examples. The qualitative research focused on the intervention being trialled (71%, 254/356), the design and conduct of the trial (15%, 54/356), the outcomes of the trial (1%, 5/356), the measures used in the trial (3%, 10/356), and the health condition in the trial (9%, 33/356). The potential value of the qualitative research to the trial endeavour included improving the external validity of trials and facilitating interpretation of trial findings. This value could be maximised by using qualitative research more at the pre-trial stage and reporting findings with explicit attention to the implications for the trial endeavour. During interviews

    1988-01-01

    This paper is aimed at describing where the research work on human factors undertaken at EDF stands in relation to this European trend and to define the problematics of cognitive phenomena in relation to all (non cognitive) human phenomena, on the one hand, and to individual aspects as compared to collective and organizational aspects, on the other. Some important trends in the research and development studies will thus be examined one lay one: - analysis of operators' activity; - analysis of the activity cognitive aspects; - problem of the impact of non-cognitive aspects

    Full Text Available Background Conducting ethically grounded research is a fundamental facet of all investigations. Nevertheless, the administrative burdens of current ethics review are substantial, and calls have been made for a reduction in research waste. Aims To describe the heterogeneity in administration and documentation required by Human Research Ethics Committees (HRECs and Research Governance Offices (RGOs across Australia. Methods In establishing a nationwide study to investigate the molecular aetiology of Giant Cell Arteritis (GCA, for which archived pathological specimens from around Australia are being recruited, we identified variation across separate HREC and RGO requirements. Submission paperwork and correspondence from each collaborating site and its representative office for research were reviewed. This data was interrogated to evaluate differences in current guidelines. Results Twenty-five pathology departments across seven Australian States collaborated in this study. All states, except Victoria, employed a single ethics review model. There was discrepancy amongst HRECs as to which application process applied to our study: seven requested completion of a “National Ethics Application Form” and three a “Low Negligible Risk” form. Noticeable differences in guidelines included whether electronic submission was sufficient. There was variability in the total number of documents submitted (range five to 22 and panel review turnaround time (range nine to 136 days. Conclusion We demonstrate the challenges and illustrate the heavy workload involved in receiving widespread ethics and governance approval across Australia. We highlight the need to simplify, homogenise, and nationalise human ethics for non-clinical trial studies. Reducing unnecessary administration will enable investigators to achieve research aims more efficiently

    2017-01-01

    INTRODUCTION Subjective Cognitive Decline (SCD) manifesting prior to clinical impairment could serve as a target population for early intervention trials in Alzheimer’s disease (AD). A working group, the Subjective Cognitive Decline Initiative (SCD-I), published SCD research criteria in the context of preclinical AD. To successfully apply them, a number of issues regarding assessment and implementation of SCD needed to be addressed. METHODS Members of the SCD-I met to identify and agree upon topics relevant to SCD criteria operationalization in research settings. Initial ideas and recommendations were discussed with other SCD-I working group members and modified accordingly. RESULTS Topics included SCD inclusion and exclusion criteria, together with the informant’s role in defining SCD presence and the impact of demographic factors. DISCUSSION Recommendations for the operationalization of SCD in differing research settings, with the aim of harmonization of SCD measurement across studies are proposed, to enhance comparability and generalizability across studies.

    Having the research capacity to identify problems, create new knowledge and most importantly translate this knowledge into practice is essential within health care. Midwifery, as well as other health professions in Australia, is challenged in building its research capacity to contribute evidence to inform clinical practice. The aim of this project was to evaluate an innovative Graduate Midwifery Research Intern Programme offered at a tertiary obstetric hospital in Western Australia, to determine what was working well and how the programme could be improved. A case study approach was used to gain feedback from graduate midwives within a Graduate Research Intern (GRI) Programme. In addition outcomes were compiled of all projects the GRI midwives contributed to. Six GRI midwives participated in a survey comprising of four open ended questions to provide feedback about the programme. Findings confirm that the GRI programme increased the graduates understanding of how research works, its capacity to define a problem, generate new knowledge and inform clinical practice. The GRI midwives' feedback suggested the programme opened their thinking to future study and gave them enhanced insight into women's experiences around childbirth. To grow our knowledge as a professional group, midwives must develop and promote programmes to build our pool of research capable midwives. By sharing our programme evaluation we hope to entice other clinical settings to consider the value in replicating such a programme within their context.

  4. Accelerator research studies: Progress report, Task B

    International Nuclear Information System (INIS)

    1985-06-01

    The main objectives in Task B of the research program are summarized as follows: (1) studies of the collective acceleration of positive ions from a localized plasma source by an intense relativistic electron beam (IREB), (2) studies of ways in which external control may be achieved over the electron beam front in order to achieve higher ion energies - the Beam Front Accelerator (BFA) concept, and (3) study of electron and ion beam generation in a new kind of compact pulsed accelerator in which energy is stored inductively and switched using a plasma focus opening switch. During the past year, substantial progress was made in each of these areas. Our exploratory research on the collective acceleration of laser-produced ions has confirmed the acceleration of C, Al, and Fe ions to peak energies in excess of 10 MeV/amu. In addition, studies of the relation between collective ion acceleration and electron beam propagation in vacuum have shed new light on the experimental processes that lead to energy transfer from electrons to ions. Meanwhile, extensive progress has been made in our attempts to use analytical theory and numerical simulation to model ion acceleration in these systems. Our resultant improved understanding of the processes that limit the peak ion energy has had a profound impact on our plans for further research in this area. Studies of the Compact Pulsed Accelerator have included both ion and electron beam extraction from the device. Its potential to reduce the volume of pulse power sources by an order of magnitude has already been demonstrated, and plans are currently underway to scale the experiment up to voltages in the 1 MV range

  5. Tire Crumb Research Study Literature Review / Gap ...

    Science.gov (United States)

    In order to more fully understand data gaps in human exposure and toxicity to tire crumb materials, ATSDR, CPSC and EPA undertook a collaborative effort in the form of a scientific literature review and subsequent gaps analysis. The first objective of the Literature Review and Gap Analysis (LRGA) collaboration was to identify the existing body of literature related specifically to human exposure to tire crumb materials through the use of synthetic turf athletic fields and playgrounds. The second objective was to characterize and summarize the relevant data from the scientific literature. The final objective was to review the summary information and identify data gaps to build on the current understanding of the state-of-the-science and inform the development of specific research efforts that would be most impactful in the near-term. Because of the need for additional information, the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (ATSDR), and the U.S. Consumer Product Safety Commission (CPSC) launched a multi-agency action plan to study key environmental human health questions. The Federal Research Action Plan includes numerous activities, including research studies (U.S. EPA, 2016). A key objective of the Action Plan is to identify key knowledge gaps.

    The costs of performing research are an important input in value of information (VOI) analyses but are difficult to assess. The aim of this study was to investigate the costs of research, serving two purposes: (1) estimating research costs for use in VOI analyses; and (2) developing a costing tool to support reviewers of grant proposals in assessing whether the proposed budget is realistic. For granted study proposals from the Netherlands Organization for Health Research and Development (ZonMw), type of study, potential cost drivers, proposed budget, and general characteristics were extracted. Regression analysis was conducted in an attempt to generate a 'predicted budget' for certain combinations of cost drivers, for implementation in the costing tool. Of 133 drug-related research grant proposals, 74 were included for complete data extraction. Because an association between cost drivers and budgets was not confirmed, we could not generate a predicted budget based on regression analysis, but only historic reference budgets given certain study characteristics. The costing tool was designed accordingly, i.e. with given selection criteria the tool returns the range of budgets in comparable studies. This range can be used in VOI analysis to estimate whether the expected net benefit of sampling will be positive to decide upon the net value of future research. The absence of association between study characteristics and budgets may indicate inconsistencies in the budgeting or granting process. Nonetheless, the tool generates useful information on historical budgets, and the option to formally relate VOI to budgets. To our knowledge, this is the first attempt at creating such a tool, which can be complemented with new studies being granted, enlarging the underlying database and keeping estimates up to date.

    Knowledge produced through applied health research is often of a form not readily accessible to or actionable by policymakers and practitioners, which hinders its implementation. Our aim was to identify research activities that can support the production of knowledge tailored to inform policy and practice. To do this, we studied an operational research approach to improving the production of applied health research findings. A 2-year qualitative study was conducted of the operational research contribution to a multidisciplinary applied health research project that was successful in rapidly informing national policy. Semi-structured interviews (n = 20) were conducted with all members of the project's research team and advisory group (patient and health professional representatives and academics). These were augmented by participant (> 150 h) and non-participant (> 15 h) observations focusing on the process and experience of attempting to support knowledge production. Data were analysed thematically using QSR NVivo software. Operational research performed a knowledge mediation role shaped by a problem-focused approach and an intent to perform those tasks necessary to producing readily implementable knowledge but outwith the remit of other disciplinary strands of the project. Three characteristics of the role were found to support this: engaging and incorporating different perspectives to improve services by capturing a range of health professional and patient views alongside quantitative and qualitative research evidence; rendering data meaningful by creating and presenting evidence in forms that are accessible to and engage different audiences, enabling them to make sense of it for practical use; and maintaining perceived objectivity and rigour by establishing credibility, perceived neutrality and confidence in the robustness of the research in order to unite diverse professionals in thinking creatively about system-wide service improvement.

    The aim was to explore the process of involving mental healthcare service users in a mental health promotion research project as research advisors and to articulate features of the collaboration which encouraged and empowered the advisors to make significant contributions to the research process and outcome. There is an increasing interest in evaluating aspects of service user involvement in nursing research. Few descriptions exist of features that enable meaningful service user involvement. We draw on experiences from conducting research which used the methodology interpretative phenomenological analysis to explore how persons with mental disorders perceived mental health. Aside from the participants in the project, five research advisors with service user experience were involved in the entire research process. We applied a case study design to explore the ongoing processes of service user involvement. Documents and texts produced while conducting the project (2012-2016), as well as transcripts from multistage focus group discussions with the research advisors, were analysed. The level of involvement was dynamic and varied throughout the different stages of the research process. Six features: leadership, meeting structure, role clarification, being members of a team, a focus on possibilities and being seen and treated as holistic individuals, were guiding principles for a salutogenic service user involvement. These features strengthened the advisors' perception of themselves as valuable and competent contributors. Significant contributions from research advisors were promoted by facilitating the process of involvement. A supporting structure and atmosphere were consistent with a salutogenic service user involvement. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    1989-01-01

    Computational mechanics is that discipline of applied science and engineering devoted to the study of physical phenomena by means of computational methods based on mathematical modeling and simulation, utilizing digital computers. The discipline combines theoretical and applied mechanics, approximation theory, numerical analysis, and computer science. Computational mechanics has had a major impact on engineering analysis and design. When applied to structural mechanics, the discipline is referred to herein as computational structural mechanics. Complex structures being considered by NASA for the 1990's include composite primary aircraft structures and the space station. These structures will be much more difficult to analyze than today's structures and necessitate a major upgrade in computerized structural analysis technology. NASA has initiated a research activity in structural analysis called Computational Structural Mechanics (CSM). The broad objective of the CSM activity is to develop advanced structural analysis technology that will exploit modern and emerging computers, such as those with vector and/or parallel processing capabilities. Here, the current research directions for the Methods and Application Studies Team of the Langley CSM activity are described.

  16. Study to define NDE research for inspection of stainless steels

    1978-08-01

    After the boiling water reactor (BWR) stress corrosion cracking incidents on 4- and 10-inch stainless steel piping, the Electric Power Research Institute (EPRI) organized a round-robin ultrasonic examination of piping removed from service (TPS-75-609). Five inspection teams participated in this program, using both a standard procedure and the individual team procedure. The original intent was to section the piping after the program to evaluate the effectiveness of state-of-the-art ultrasonics in finding stress corrosion cracking. The sectioning was delayed, however, to allow research and development (R and D) groups time to perform basic measurements aimed at determining optimum search unit and instrument characteristics for the ultrasonic examination of stainless steel piping and to study the applicability of various advanced inspection methods. This additional effort was funded as part of an EPRI technical planning study (TPS-75-620), A Study to Define NDE Research for Inspection of Stainless Steels. Inspection methods evaluated in this study included (1) processing of manual scan data using a miniature programmable calculator (Aerojet Nuclear); (2) investigation into the performance characteristics of three experimental ultrasonic transducers (Battelle-Columbus Laboratories); (3) analysis of fundamental ultrasonic response data from intergranular stress corrosion cracks in stainless steels (Southwest Research Institute); and (4) a feasibility study of advanced signal processing and pattern recognition for analyzing flaws in stainless steel piping (Ultrasonics International). The results of the studies compiled in the report have indicated the direction for future research and development and have formed the basis for the recently initiated EPRI Research Project 892, Ultrasonic System Optimization

    2017-01-01

    An online survey was conducted by twelve professional chaplain organizations to assess chaplains' attitudes about and involvement in research. A total of 2,092 chaplains from 23 countries responded to the survey. Over 80% thought research was definitely important and nearly 70% thought chaplains should definitely be research literate. Just over 40% said they regularly read research articles and almost 60% said they occasionally did. The respondents rated their own research literacy as 6.5 on a 0-10 scale. Significant positive inter-correlations were found among all four measures: importance of (a) research and (b) research literacy; (c) frequency of reading articles; and (d) research literacy rating. Approximately 35% were never involved, 37% had been involved, 17% were currently involved, and 11% expected to be involved in research. The last three groups were significantly more likely to think research and research literacy were important and to read research articles than chaplains who were never involved in research. Given chaplains' interest in research, actions should be undertaken to facilitate further research engagement.

    The question of how to measure, assess and optimise the returns from investment in health and medical research (HMR) is a highly policy-relevant issue. Research Impact Assessment Frameworks (RIAFs) provide a conceptual measurement framework to assess the impact from HMR. The aims of this study were (1) to elicit the views of Medical Research Institutes (MRIs) regarding objectives, definitions, methods, barriers, potential scope and attitudes towards RIAFs, and (2) to investigate whether an assessment framework should represent a retrospective reflection of research impact or a prospective approach integrated into the research process. The wider objective was to inform the development of a draft RIAF for Australia's MRIs. Purposive sampling to derive a heterogeneous sample of Australian MRIs was used alongside semi-structured interviews with senior executives responsible for research translation or senior researchers affected by research impact initiatives. Thematic analysis of the interview transcriptions using the framework approach was then performed. Interviews were conducted with senior representatives from 15 MRIs. Participants understood the need for greater research translation/impact, but varied in their comprehension and implementation of RIAFs. Common concerns included the time lag to the generation of societal impacts from basic or discovery science, and whether impact reflected a narrow commercialisation agenda. Broad support emerged for the use of metrics, case study and economic methods. Support was also provided for the rationale of both standardised and customised metrics. Engendering cultural change in the approach to research translation was acknowledged as both a barrier to greater impact and a critical objective for the assessment process. Participants perceived that the existing research environment incentivised the generation of academic publications and track records, and often conflicted with the generation of wider impacts.

    2016-06-01

    We describe and evaluate a summer undergraduate research project and experience by one of us (AA), under the supervision of the other (JP). The aim of the project was to sample current approaches to analyzing variable star data, and topics related to the study of Mira variable stars and their astrophysical importance. This project was done through the Summer Undergraduate Research Program (SURP) in astronomy at the University of Toronto. SURP allowed undergraduate students to explore and learn about many topics within astronomy and astrophysics, from instrumentation to cosmology. SURP introduced students to key skills which are essential for students hoping to pursue graduate studies in any scientific field. Variable stars proved to be an excellent topic for a research project. For beginners to independent research, it introduces key concepts in research such as critical thinking and problem solving, while illuminating previously learned topics in stellar physics. The focus of this summer project was to compare observations with structural and evolutionary models, including modelling the random walk behavior exhibited in the (O-C) diagrams of most Mira stars. We found that the random walk could be modelled by using random fluctuations of the period. This explanation agreed well with observations.

    2017-05-01

    Background When conducting qualitative research, participants usually share lots of personal and private information with the researcher. As researchers, we must preserve participants' identity and confidentiality of the data. Objective To critically analyze an ethical conflict encountered regarding confidentiality when doing qualitative research. Research design Case study. Findings and discussion one of the participants in a study aiming to explain the meaning of living with HIV verbalized his imminent intention to commit suicide because of stigma of other social problems arising from living with HIV. Given the life-threatening situation, the commitment related to not disclosing the participant's identity and/or the content of the interview had to be broken. To avoid or prevent suicide, the therapist in charge of the case was properly informed about the participant's intentions. One important question arises from this case: was it ethically appropriate to break the confidentiality commitment? Conclusion confidentiality could be broken if a life-threatening event is identified during data collection and participants must know that. This has to be clearly stated in the informed consent form.

    2015-01-01

    The NASA Protoflight Research Initiative is an internal NASA study conducted within the Office of the Chief Engineer to better understand the use of Protoflight within NASA. Extensive literature reviews and interviews with key NASA members with experience in both robotic and human spaceflight missions has resulted in three main conclusions and two observations. The first conclusion is that NASA's Protoflight method is not considered to be "prescriptive." The current policies and guidance allows each Program/Project to tailor the Protoflight approach to better meet their needs, goals and objectives. Second, Risk Management plays a key role in implementation of the Protoflight approach. Any deviations from full qualification will be based on the level of acceptable risk with guidance found in NPR 8705.4. Finally, over the past decade (2004 - 2014) only 6% of NASA's Protoflight missions and 6% of NASA's Full qualification missions experienced a publicly disclosed mission failure. In other words, the data indicates that the Protoflight approach, in and of it itself, does not increase the mission risk of in-flight failure. The first observation is that it would be beneficial to document the decision making process on the implementation and use of Protoflight. The second observation is that If a Project/Program chooses to use the Protoflight approach with relevant heritage, it is extremely important that the Program/Project Manager ensures that the current project's requirements falls within the heritage design, component, instrument and/or subsystem's requirements for both the planned and operational use, and that the documentation of the relevant heritage is comprehensive, sufficient and the decision well documented. To further benefit/inform this study, a recommendation to perform a deep dive into 30 missions with accessible data on their testing/verification methodology and decision process to research the differences between Protoflight and Full Qualification

  4. Aims and methods of education: A recapitulation

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available This paper gives an overview of principal distinction between the aims of the so-called "traditional" and "progressive" education and respective pedagogies associated with each. The term "traditional" education is used to denote the kind of education that prepares people for their role in society as it is, while the term "progressive" is used for education that aspires to equip mankind with capacity to shape the change of society. The paper raises some critical questions about the role of pedagogy in achieving the aims of the progressive model, arguing that the employment of "progressive" methods does not necessarily guarantee the achievement of the commonly professed purposes of progressive education. This is illustrated in the paper by the results of a study in English schools showing how despite the claim of progressive methods, teachers tend to retain traditional attitudes and on the other hand, how even traditional teaching methods can serve the progressive purpose. This is not to advocate for the traditional pedagogy, but to suggest that it might be something other than pedagogy that makes a critical difference in educating liberal-minded citizens of the future. In this sense the paper explores the role of other factors that make a difference towards progressive education, such as democratization of human relations in school ethos and respect for children's freedom.

    Health Care covers three areas of interest for cold atmospheric pressure plasmas: Cosmetics, Hygiene and Medicine. These areas can be subdivided into personal and professional care. In this review will concentrate on Hygiene and Medicine. In professional hygiene the most important plasma contribution is sterilization, decontamination and disinfection. The main aim is the prevention of diseases or their containment. Progress in the development of efficient bactericidal plasma sources has been rapid, so that it appears realistic to use plasmas to combat nosocomial infections as well as community associated infections in the not too distant future. The advantages of plasma devices – they use air and electricity only, there are no waste products, they are inexpensive to manufacture and operate, easy to transport and install, and bactericidal effects are fast (seconds). Plasmas can efficiently kill resistant bacteria (e.g. MRSA) and tests have shown no resistance build-up so far. With an estimated 2 Million hospital induced infections each year in the US alone, and about 100.000 resulting deaths, very efficient, safe and fast hospital plasma hygiene devices would appear to be a very important weapon to help contain the spread of infectious diseases. In Medicine there are a number of ambitious ideas and aims. Plasmas can be “designed” to some extent. They can include different active species that can have an effect at the cellular level. There are ionic atoms and molecules, whose medical use need to be evaluated – the vision is that a new area of “plasma pharmacy” could develop. First steps are currently being taken in biological studies. Also the excited atoms in cold atmospheric plasmas may make cell walls more permeable for such species. (author)

    2016-06-01

    In order to develop and evaluate interventions in rehabilitation research a wide range of empirical research methods may be adopted. Qualitative research methods emphasize the relevance of an open research focus and a natural proximity to research objects. Accordingly, using qualitative methods special benefits may arise if researchers strive to identify and organize unknown information aspects (inductive purpose). Particularly, quantitative research methods require a high degree of standardization and transparency of the research process. Furthermore, a clear definition of efficacy and effectiveness exists (deductive purpose). These paradigmatic approaches are characterized by almost opposite key characteristics, application standards, purposes and quality criteria. Hence, specific aspects have to be regarded if researchers aim to select or combine those approaches in order to ensure an optimal gain in knowledge. © Georg Thieme Verlag KG Stuttgart · New York.

  14. Aims and accomplishments of surface theory

    International Nuclear Information System (INIS)

    Feibelman, P.J.

    1979-01-01

    The goals of surface science include the understanding of surface structure, transport and chemistry. However, present activities are mainly focussed on the most basic problem, viz., what are the constituents of a given surface and where are they located. Theorists are approaching this surface characterization problem from two sides. To make better use of the data available from the many experimental surface probes, an understanding of the force laws which govern the motion of probe-particles near surfaces is being developed, and the relation between the excitation and ground state spectra of a solid are being studied. In order to develop a predictive capability regarding surface structure, a variety of intrinsic surface properties are being studied, including the nature of bonds at transition metal surfaces, the meaning of bond locality in extended systems, and the electronic factors underlying the forces which govern surface geometry. These studies often raise technical issues such as the validity of using local exchange-correlation potentials and the applicability of cluster calculations to the analysis of extended surface situations, which, however, should not obscure the main thrust of current work - empirical and predictive surface structure determination. These points are illustrated with examples from recent research and ways in which experimental surface work might assist theoretical efforts are indicated

  15. On correlations in IMRT planning aims

    Roy, Arkajyoti; Das, Indra J.

    2016-01-01

    The purpose was to study correlations amongst IMRT DVH evaluation points and how their relaxation impacts the overall plan. 100 head‐and‐neck cancer cases, using the Eclipse treatment planning system with the same protocol, are statistically analyzed for PTV, brainstem, and spinal cord. To measure variations amongst the plans, we use (i) interquartile range (IQR) of volume as a function of dose, (ii) interquartile range of dose as a function of volume, and (iii) dose falloff. To determine correlations for institutional and ICRU goals, conditional probabilities and medians are computed. We observe that most plans exceed the median PTV dose (average D50 = 104% prescribed dose). Furthermore, satisfying D50 reduced the probability of also satisfying D98, constituting a negative correlation of these goals. On the other hand, satisfying D50 increased the probability of satisfying D2, suggesting a positive correlation. A positive correlation is also observed between the PTV V105 and V110. Similarly, a positive correlation between the brainstem V45 and V50 is measured by an increase in the conditional median of V45, when V50 is violated. Despite the imposed institutional and international recommendations, significant variations amongst DVH points can occur. Even though DVH aims are evaluated independently, sizable correlations amongst them are possible, indicating that some goals cannot be satisfied concurrently, calling for unbiased plan criteria.

    2008-07-15

    The present work is concerned with a power upgrading study of Tehran Research Reactor (TRR). The upgrading study is aimed at investigating the possibility of raising power of the TRR from the current level of 5 MW{sub th} to a higher level without violating the original thermal-hydraulic safety criteria. The existing core, comprising 22 standard fuel elements and five control fuel elements, is used for the analyses. Different reactor thermal powers (5-11 MW) and different core coolant flow rates (500-921 m{sup 3}/h) are considered. It is shown that, for the present core, this goal could be achieved safely by gradually opening the butterfly control valve until the desired coolant flow rate is reached. The TRR power could be upgraded up to around 7.5 MW{sub th} with the total power peaking factor maintained at less than or equal to 3.0.

One motivation for such aims is the assumption that numerical underrepresentation of groups manifests discrimination against them. In this article, I articulate...... representational aims in a way that best captures this rationale. My main claim is that the achievement of such representational aims is reducible to the elimination of the effects of wrongful discrimination on individuals and that this very important concern is, in principle, compatible with the representation...... of discrimination against numerically overrepresented groups, or overlook the innocently different ambitions of some numerically underrepresented groups.

    Among several treatment processes suitable for the Northeastern semi-arid area of the Brazil, the reverse osmosis presents growing application. A plant of reverse osmosis that uses photovoltaic technology attends to the needs of that area, since it does not demand local electrical grid. The present paper shows a statistical study of radiation making use of data collected in the Department of Electrical Engineering of the Federal University of Ceara, in Fortaleza, and it has the aim of be used in the project of a plant of reverse osmosis supplied by photovoltaic panels. The results of the study allow the comparison of different number of panels, radiation levels used to supply the plant and times of operation. The results are exposed in form of graphs such as: solar radiation, histograms of solar radiation, accumulated time and maximum continuous periods with solar radiation above 300 and 500 W/m2. It was observed considerable annual differences in the behaviour of the radiation, as well as a gradual variation along one year, what reflects the annual difference of the radiation behaviour in wet and dry periods, and this will influences directly the strategy of operation of the plant.

    Using an example of qualitative research embedded in a non-surgical feasibility trial, we explore the benefits of including qualitative research in trial design and reflect on epistemological challenges. We interviewed 18 trial participants and used methods of Interpretive Phenomenological Analysis. Our findings demonstrate that qualitative research can make a valuable contribution by allowing trial stakeholders to see things from alternative perspectives. Specifically, it can help to make specific recommendations for improved trial design, generate questions which contextualize findings, and also explore disease experience beyond the trial. To make the most out of qualitative research embedded in quantitative design it would be useful to (a) agree specific qualitative study aims that underpin research design, (b) understand the impact of differences in epistemological truth claims, (c) provide clear thematic interpretations for trial researchers to utilize, and (d) include qualitative findings that explore experience beyond the trial setting within the impact plan. © The Author(s) 2016.

    Obtaining effective informed consent from research participants is a prerequisite to the conduct of an ethically sound research. Yet it is believed that obtaining quality informed consent is generally difficult in settings with low socioeconomic status. This is so because of the alleged undue inducements and therapeutic misconception among participants. However, there is a dearth of data on factors that motivate research participants to take part in research. Hence, this study was aimed at filling this gap in the Malawian context. We conducted 18 focus group discussions with community members in urban and rural communities of Blantyre in Malawi. Most participants reported that they accepted the invitation to participate in research because of better quality treatment during study also known as ancillary care, monetary and material incentives given to participants, and thorough medical diagnosis. © The Author(s) 2014.

    2014-06-01

    Full Text Available Aim: The orthodontic movement is associated with a process of tissue remodeling together with the release of several chemical mediators in periodontal tissues. Each mediator is a potential marker of tooth movement and expresses biological processes as: tissue inflammation and bone remodeling. Different amounts of every mediator are present in several tissues and fluids of the oral cavity. Therefore, there are different methods that allow sampling with several degrees of invasiveness. Chemical mediators are also substances of different molecular nature, and multiple kind of analysis methods allow detection. The purpose of this study was to draft the best research protocol for an optimal study on orthodontic movement efficiency. Methods: An analysis of the international literature have been made, to identify the gold standard of each aspect of the protocol: type of mediator, source and method of sampling and analysis method. Results: From the analysis of the international literature was created an original research protocol for the study and the assessment of the orthodontic movement, by using the biomarkers of the tooth movement. Conclusions: The protocol created is based on the choice of the gold standard of every aspect already analyzed in the literature and in existing protocols for the monitoring of orthodontic tooth movement through the markers of tooth movement. Clinical trials re required for the evaluation and validation of the protocol created.

    In the United Kingdom (UK), official bodies such as the Department of Health and research funders such as the National Institute for Health Research support and encourage lay involvement in all stages of research studies. The SHARED study has had substantial patient and public involvement (PPI) from developing the idea to dissemination. The aim of the study has been to develop recommendations led by service users for health and social care professionals to use at hospital discharge and in care planning for people living with memory loss and their carers. This article is about how the study started and the benefits, costs and challenges we encountered as the lead and lay co-researchers. Once we were successful with the grant application, we had to recruit and train the lay co-researchers and obtain various approvals before we could start the project. We had various support from funders, the Research Ethics Committee, lay members of Alzheimer's Society and from the lay co-researchers. However, we encountered some challenges with paying the lay co-researchers and with getting the approval for the co-researchers to interview staff on NHS premises. The challenges were overcome eventually but some aspects of the study changed because of this. We suggest that some changes could be made to the research system which would lead to greater inclusion of the lay co-researchers in research studies and would make the process more straightforward for the research team. Background Involving patients and the public in all stages of research has been the focus of the SHARED study. Patient and public involvement (PPI) is an important strategic priority for the Department of Health and funders such as the National Institute for Health Research.

    National nursing workforce studies are important for evidence-based policymaking to improve nursing human resources globally. Survey instrument translation and contextual adaptation along with level of experience of the research team are key factors that will influence study implementation and results in countries new to health workforce studies. This study's aim was to describe the pre-data collection instrument adaptation challenges when designing the first national nursing workforce study in Poland while participating in the Nurse Forecasting: Human Resources Planning in Nursing project. A descriptive analysis of the pre-data collection phase of the study. Instrument adaptation was conducted through a two-phase content validity indexing process and pilot testing from 2009 to September 2010 in preparation for primary study implementation in December 2010. Means of both content validation phases were compared with pilot study results to assess for significant patterns in the data. The initial review demonstrated that the instrument had poor level of cross-cultural relevance and multiple translation issues. After revising the translation and re-evaluating using the same process, instrument scores improved significantly. Pilot study results showed floor and ceiling effects on relevance score correlations in each phase of the study. The cross-cultural adaptation process was developed specifically for this study and is, therefore, new. It may require additional replication to further enhance the method. The approach used by the Polish team helped identify potential problems early in the study. The critical step improved the rigour of the results and improved comparability for between countries analyses, conserving both money and resources. This approach is advised for cross-cultural adaptation of instruments to be used in national nursing workforce studies. Countries seeking to conduct national nursing workforce surveys to improve nursing human resources policies may

    Full Text Available There have been many studies conducted to determine variables that affect professional contentment. Some of these studies hav e looked at factors such as organizational involvement and commitment to organi zations. Several of these studies found that a larger percentage of unemploye d and employed personnel expressed dissatisfaction with their work commitmen t. The implications of those studies suggested that unemployed could reflect und erlying adjustment disorders which have an impact on someone’s potential for suc cessful employment. However, for those who are contented with their per formance, in the long run these workers would have a higher gratification. Th ey would give more attention on the quality of their work, more committed to the organization, have a higher retention rates, and would be more productive. Refl ecting on these findings and how severe this issue may render, this study is con ducted to identify the level of professional satisfaction of the academic staffs in a research university in the southern part of Malaysia. This paper will present the findings of the study which aimed to determine the level of satisfaction based on factors such as pay, promotion, supervision, fringe benefit, contingent eward, operating condition, coworkers, nature of work and communication

    Full Text Available Accidental hypothermia refers to a state of lowering of core body temperature down to 35 ℃induced by drowning, burial in snow and prolonged exposure to cold environment, etc. Hypothermia may affect the cardiovascular system, respiratory system, digestive system, etc. The triad consisting "hypothermia, acidosis and coagulopathy" is an important factor accelerating the death of patients. Early, timely application of rewarming measures is regarded as the basic principle in treatment of hypothermia. A series of rewarming measures, such as infusion of warm fluids, inspiration of warm air, abdominal infusion of warm fluid, instruction of warm fluid into pleural cavity, intravenous infusion of warm fluid, rewarming through ECMO, etc. have been used recently. Advance in research on the classification of hypothermia, its impact to the body and the treatment methods are reviewed in present paper. DOI: 10.11855/j.issn.0577-7402.2016.04.15

  5. Tutorial: Asteroseismic Stellar Modelling with AIMS

    Science.gov (United States)

    Lund, Mikkel N.; Reese, Daniel R.

    The goal of aims (Asteroseismic Inference on a Massive Scale) is to estimate stellar parameters and credible intervals/error bars in a Bayesian manner from a set of asteroseismic frequency data and so-called classical constraints. To achieve reliable parameter estimates and computational efficiency, it searches through a grid of pre-computed models using an MCMC algorithm—interpolation within the grid of models is performed by first tessellating the grid using a Delaunay triangulation and then doing a linear barycentric interpolation on matching simplexes. Inputs for the modelling consist of individual frequencies from peak-bagging, which can be complemented with classical spectroscopic constraints. aims is mostly written in Python with a modular structure to facilitate contributions from the community. Only a few computationally intensive parts have been rewritten in Fortran in order to speed up calculations.

  6. CURRICULUM MATTERS: Aims assessments and workplace needs

    Science.gov (United States)

    Black, Paul

    1997-09-01

    This paper attempts to consider the aims that undergraduate physics degree courses actually reflect and serve in the light of the employment patterns of graduates and of the expressed needs of employers. It reviews the results of analyses of what degree examinations actually test, and goes on to quote criticisms of their courses and radical proposals to change them adopted by the UK conference of physics professors. The discussion is then broadened by discussion of evidence, about the employment of graduates and about the priorities that some industrialists now give in the qualities that they look for when recruiting new graduates. The evidence leads to a view that radical changes are needed, both in courses and examinations, and that there is a need for university departments to work more closely with employers in re-formulating the aims and priorities in their teaching.

    Whilst international safeguarding of fissile materials against abuse has been the subject of extensive debate, little public attention has so far been devoted to the internal security of these materials. All countries using nuclear energy for peaceful purposes have laid down appropriate regulations. In the Federal Republic of Germany safeguards are required, for instance, by the Atomic Energy Act, and are therefore a prerequisite for licensing. The aims and methods of national nuclear materials management are contrasted with viewpoints on international safeguards

    Case study research is a comprehensive method that incorporates multiple sources of data to provide detailed accounts of complex research phenomena in real-life contexts. However, current models of case study research do not particularly distinguish the unique contribution observation data can make. Observation methods have the potential to reach beyond other methods that rely largely or solely on self-report. This article describes the distinctive characteristics of case study observational research, a modified form of Yin's 2014 model of case study research the authors used in a study exploring interprofessional collaboration in primary care. In this approach, observation data are positioned as the central component of the research design. Case study observational research offers a promising approach for researchers in a wide range of health care settings seeking more complete understandings of complex topics, where contextual influences are of primary concern. Future research is needed to refine and evaluate the approach.

    1996-09-01

    In support of a two-phase approach to privatizing the processing of hazardous and radioactive waste at Hanford, research-scale melter (RSM) experiments were conducted to determine feed processing characteristics of two potential privatization Phase 1 high-level waste glass formulations and to determine if increased Ag, Te, and noble metal amounts would have bad effects. Effects of feed compositions and process conditions were examined for processing rate, cold cap behavior, off-gas, and glass properties. The 2 glass formulations used were: NOM-2 with adjusted waste loading (all components except silica and soda) of 25 wt%, and NOM-3 (max waste loaded glass) with adjusted waste loading of 30 wt%. The 25 wt% figure is the minimum required in the privatization Request for Proposal. RSM operated for 19 days (5 runs). 1010 kg feed was processed, producing 362 kg glass. Parts of runs 2 and 3 were run at 10 to 30 degrees above the nominal temperature 1150 C, with the most significant processing rate increase in run 3. Processing observations led to the choice of NOM-3 for noble metal testing in runs 4 and 5. During noble metal testing, processing rates fell 50% from baseline. Destructive analysis showed that a layer of noble metals and noble metal oxides settled on the floor of the melter, leading to current ``channeling`` which allowed the top section to cool, reducing production rates.

    Moll, Sandra

    2012-01-01

    The purpose of this paper is to examine key challenges associated with conducting politically sensitive research within a workplace setting, and to highlight strategic partnerships that can be developed to address these challenges. The author's research on employee mental health issues within a large healthcare facility serves as the foundation for identification and description of "political minefields" that investigators may encounter when conducting organizational case study research. Key methodological principles from the literature on qualitative case study research will frame discussion of how to understand and address political sensitivities in the research process. The benefits of conducting organizational case study research will be outlined, followed by discussion of methodological challenges that can emerge in negotiating entry, collecting data (gatekeepers, researcher reflexivity, participant authenticity and non-maleficence), and communicating research findings. Courage, collaboration and clear communication with stakeholders at all levels of the organization are critical to the success of workplace based case study research.

    With a growing need for developing future physician scientists, identifying characteristics of medical students who are likely to benefit from research training programs is important. This study assessed if specific learning styles of medical students, participating in federally funded short-term research training programs, were associated with research self-efficacy, a potential predictor of research career success. Seventy-five first-year medical students from 28 medical schools, selected to participate in two competitive NIH-supported summer programs for research training in aging, completed rating scales to evaluate learning styles at baseline, and research self-efficacy before and after training. We examined associations of individual learning styles (visual-verbal, sequential-global, sensing-intuitive, and active-reflective) with students' gender, ranking of medical school, and research self-efficacy. Research self-efficacy improved significantly following the training programs. Students with a verbal learning style reported significantly greater research self-efficacy at baseline, while visual, sequential, and intuitive learners demonstrated significantly greater increases in research self-efficacy from baseline to posttraining. No significant relationships were found between learning styles and students' gender or ranking of their medical school. Assessments of learning styles may provide useful information to guide future training endeavors aimed at developing the next generation of physician-scientists. © 2014 Wiley Periodicals, Inc.

    Full Text Available More than two-thirds of today's world trade comprises of transactions between related legal persons. Prices for the above-mentioned transactions within legal person or group of related legal persons are called transfer pricing. The aim of this paper is to present the transfer prices as well as the main objectives of transfer pricing. Also, this paper explains application of transfer pricing in the Republic of Serbia and the normative rules that cover the issue of transfer pricing, their determination and their application in the calculation. Overall, there has been a great deal of attention paid to the transfer pricing in national and international levels.

    Despite an increase in inclusive studies in recent years, research on the views of the people with and without disabilities who have participated in these studies is scarce. The aim of this study was to explore the perceptions and views of advisors with intellectual disabilities and non-disabled researchers who collaborated together on a joint project to study transition to adulthood. Two questionnaires were devised, one for advisors and one for researchers; two focus groups were held with people with intellectual disabilities, three focus groups with researchers, and one focus group with all participants together. Thematic analysis was used for the data analysis. The advisors valued this experience as an opportunity to learn new skills, freely express themselves on matters that affect them, and engage in a socially valued activity. The researchers considered that the participation of people with intellectual disabilities contributed to improving the quality of the research. The study provides a better understanding of inclusive research processes by taking into account participants' views. © 2015 John Wiley & Sons Ltd.

  18. Accelerator research studies: Annual progress report

    International Nuclear Information System (INIS)

    1988-01-01

    Our major goal in this experiment is to study the physics of a space-charge dominated beam propagating through a long, periodic transport channel consisting in our case of 38 solenoid lenses two of which are being used to match the beam from the gun into the periodic lattice. In addition, a small separate test stand gives us the capability of studying different electron gun designs including measurements of beam perveance and emittance, beam propagation in drift space and through a single solenoid lens. Most of our transport studies in the periodic channel have been conducted with a 5 keV, 200 mA electron beam from a gun with a 1-inch diameter thermionic cathode. The beam physics phenomena of greatest interest are instabilities due to resonant interaction between the beam and the periodic lattice, non-linear effects due to external forces (e.g., spherical lens aberrations) or due to nonuniform charge distributions, beam off-centering and misalignments which also include the effects of image forces. In principle, all of these effects may lead to emittance growth and beam loss. An important question is whether there exists a ''window'' of 100% transmission and minimal emittance growth in such a long periodic channel. 28 refs

    The study is planned as an intensive search for the late effects of single, whole-body radiation from the Hiroshima and Nagasaki bombs. Although dosimetry information is by no means definitive at this time, preliminary information suggests that the effects of radiation doses up to 600 rads can be effectively studied in the surviving samples. The lower limit is moot, depending on the magnitude of the effect produced and the sensitivity of the study. The upper limit is also somewhat uncertain, as the most closely exposed individuals were more often heavily shielded. The potential radiation effects may be classified as follows: (1) alterations in the incidence of disease; (2) alterations in the natural history of disease, with or without alteration in incidence; (3) development of physiological or biochemical changes, or markers, short of actual disease; (4) nonspecific changes in vigor, acceleration of aging; and (5) occurrence of new diseases. It is proposed to conduct a search sufficiently intensive to detect effects of all five types. It is also a specific objective of this investigation to illuminate the pathogenesis of diseases of increased incidence, or of new diseases, if such be found. Also of interest is the matter of genetic or biochemical factors associated with survival and with the appearance of acute radiation symptoms. Survivors represent a truncated sample and selective host factors may have played a part in both survival and the liklihood of acute radiation symptoms. 17 reference.

  20. Guidelines for Conducting Positivist Case Study Research in Information Systems

    Directory of Open Access Journals (Sweden)

    Graeme Shanks

    2002-11-01

    Full Text Available The case study research approach is widely used in a number of different ways within the information systems community. This paper focuses on positivist, deductive case study research in information systems. It provides clear definitions of important concepts in positivist case study research and illustrates these with an example research study. A critical analysis of the conduct and outcomes of two recently published positivist case studies is reported. One is a multiple case study that validated concepts in a framework for viewpoint development in requirements definition. The other is a single case study that examined the role of social enablers in enterprise resource planning systems implementation. A number of guidelines for successfully undertaking positivist case study research are identified including developing a clear understanding of key concepts and assumptions within the positivist paradigm; providing clear and unambiguous definitions of the units and interactions when using any theory; carefully defining the boundary of the theory used in the case study; using hypotheses rather than propositions in the empirical testing of theory; using fuzzy or probabilistic propositions in recognising that reality can never be perfectly known; selecting case studies carefully, particularly single case studies; and recognising that generalisation from positivist, single case studies is inherently different from generalisation from single experiments. When properly undertaken, positivist, deductive case study research is a valuable research approach for information systems researchers, particularly when used within pluralist research programs that use a number of different research approaches from different paradigms.

    2018-03-05

    Concerns over the need to improve translational aspects of genetics research studies and engaging community members in the research process have been noted in the literature and raised by patient advocates. In addition to the work done by patient advocacy groups, organizations such as the Patient-Centered Outcomes Research Institute advocate for a change in the culture of research from being researcher-driven to becoming more patient-driven. Our project, Autism Genetics and Outcomes (AutGO), consists of two phases. The goal for phase I was to initiate a general discussion around the main topic (i.e., linking genetics and outcomes research). We used the Patient-Centered Outcomes Research Institute engagement approach to: (aim 1) develop a partnership with a wide range of stakeholders to assess their perspective on developing projects that use both genetics and outcomes research data/principles; (aim 2) identify barriers, facilitators, and needs to promote engagement in patient-centered genetics research; and (aim 3) distill and describe actions that may facilitate utilization of patient/parent perspectives in designing genetics research studies. In phase I, we formed a community advisory board composed of 33 participants, including outcomes and genetics researchers, clinicians, healthcare providers, patients/family members, and community/industry representatives, and convened six sessions over the 12-month period. We structured the sessions as a combination of online PowerPoint presentations, surveys, and in-person group discussions. During the sessions, we discussed topics pertaining to linking genetics and outcomes research and reviewed relevant materials, including patient stories, research projects, and existing resources. Two sets of surveys, project evaluations (k = 2) and session evaluations (k = 6), were distributed among participants. Feedback was analyzed using content analysis strategies to identify the themes and subthemes. Herein, we describe: the

    The analysis of the data for a storm on April 4, 1964, showed that in spite of all efforts to obtain a dynamically and internally consistent three-dimensional analysis of conventional wind, pressure, and temperature data, there remain ambiguities of 50 to 100 miles in the horizontal location of the boundaries of the stratospheric air. Missing wind data and temperature errors, though not disastrous in routine meteorological analysis, can seriously affect the potential vorticity computations for several isentropic surfaces. Trajectory analyses introduce additional errors. Aircraft measurements of fallout beta activity, when carefully planned and made at map time, can improve the precision to 1000 feet in the vertical, and to a few miles in the horizontal. This precision is necessary for conclusive proof of the capture of radioactive particles from the stratosphere by precipitating clouds. However, for large-scale global studies of fallout transport, errors of 50 to 100 miles in the location of air parcels with certain potential. During the 1963 study, it was found that the flow patterns at different levels were seriously affected by coding and plotting errors in the radiosonde data which often escape attention in conventional upper air analyses

    Full Text Available Abstract Background Research evidence underpins best practice, but is not always used in healthcare. The Promoting Action on Research Implementation in Health Services (PARIHS framework suggests that the nature of evidence, the context in which it is used, and whether those trying to use evidence are helped (or facilitated affect the use of evidence. Urinary incontinence has a major effect on quality of life of older people, has a high prevalence, and is a key priority within European health and social care policy. Improving continence care has the potential to improve the quality of life for older people and reduce the costs associated with providing incontinence aids. Objectives This study aims to advance understanding about the contribution facilitation can make to implementing research findings into practice via: extending current knowledge of facilitation as a process for translating research evidence into practice; evaluating the feasibility, effectiveness, and cost-effectiveness of two different models of facilitation in promoting the uptake of research evidence on continence management; assessing the impact of contextual factors on the processes and outcomes of implementation; and implementing a pro-active knowledge transfer and dissemination strategy to diffuse study findings to a wide policy and practice community. Setting and sample Four European countries, each with six long-term nursing care sites (total 24 sites for people aged 60 years and over with documented urinary incontinence Methods and design Pragmatic randomised controlled trial with three arms (standard dissemination and two different programmes of facilitation, with embedded process and economic evaluation. The primary outcome is compliance with the continence recommendations. Secondary outcomes include proportion of residents with incontinence, incidence of incontinence-related dermatitis, urinary tract infections, and quality of life. Outcomes are assessed at baseline

    The major effort reported is the study of the feasibility of a 300 MW gyroklystron at ∼9 GHz, and substantial progress has been made. A four-cavity gyroklystron design has been shown to be capable of linear gain as high as 66 dB and to be marginally stable against oscillation in any mode. AM and PM sensitivities to fluctuation in system parameters have also been calculated in the regime of linear operation. Initial non-linear design calculations have also been carried out which include the effect of tapering the axial magnetic guide field over the length of a gyroklystron circuit. Although these calculations are preliminary they do indicate potential for significant efficiency enhancement by magnetic field shaping techniques

HOT detectors allowing to push size weight and power (SWaP) of Integrated Detectors Cooler Assemblies (IDCA's) to a new level. Key component mainly driving achievable weight, volume and power consumption is the cryocooler. AIM cryocooler developments are focused on compact, lightweight linear cryocoolers driven by compact and high efficient digital cooler drive electronics (DCE) to also achieve highest MTTF targets. This technology is using moving magnet driving mechanisms and dual or single piston compressors. Whereas SX030 which was presented at SPIE in 2012 consuming less 3 WDC to operate a typical IDCA at 140K, next smaller cooler SX020 is designed to provide sufficient cooling power at detector temperature above 160K. The cooler weight of less than 200g and a total compressor length of 60mm makes it an ideal solution for all applications with limited weight and power budget, like in handheld applications. For operating a typical 640x512, 15μm MW IR detector the power consumption will be less than 1.5WDC. MTTF for the cooler will be in excess of 30,000h and thus achieving low maintenance cost also in 24/7 applications. The SX020 compressor is based on a single piston design with integrated passive balancer in a new design achieves very low exported vibration in the order of 100mN in the compressor axis. AIM is using a modular approach, allowing the chose between 5 different compressor types for one common Stirling expander. The 6mm expander with a total length of 74mm is now available in a new design that fits into standard dewar bores originally designed for rotary coolers. Also available is a 9mm coldfinger in both versions. In development is an ultra-short expander with around 35mm total length to achieve highest compactness. Technical

    2016-01-01

    Successful recruitment is vital for any research study. Difficulties in recruitment are not uncommon and can have important implications. This is particularly relevant to research conducted in affective disorders due to the nature of the conditions and the clinical services that serve these patients. Recently, online public advertisements have become more generally accessible and may provide an effective way to recruit patient populations. However, there is paucity of evidence on their viability as a method of recruiting patients into studies of disease mechanisms in these disorders. Public advertisement methods can be useful when researchers require specific populations, such as those not receiving pharmacological treatment. This work describes our experience in successfully recruiting participants into neuroimaging research studies in affective disorders using online public advertisements. Results suggest that these online public advertisements are an effective method for successfully recruiting participants with affective disorders into research studies, particularly for research focusing on disease mechanisms in specific populations.

    Communities of practice are based on the idea that learning involves a group of people exchanging experiences and knowledge. The e-MPODERA project aims to assess the effectiveness of a virtual community of practice aimed at improving primary healthcare professional attitudes to the empowerment of patients with chronic diseases. This paper describes the protocol for a cluster randomized controlled trial. We will randomly assign 18 primary-care practices per participating region of Spain (Catalonia, Madrid and Canary Islands) to a virtual community of practice or to usual training. The primary-care practice will be the randomization unit and the primary healthcare professional will be the unit of analysis. We will need a sample of 270 primary healthcare professionals (general practitioners and nurses) and 1382 patients. We will perform randomization after professionals and patients are selected. We will ask the intervention group to participate for 12 months in a virtual community of practice based on a web 2.0 platform. We will measure the primary outcome using the Patient-Provider Orientation Scale questionnaire administered at baseline and after 12 months. Secondary outcomes will be the sociodemographic characteristics of health professionals, sociodemographic and clinical characteristics of patients, the Patient Activation Measure questionnaire for patient activation and outcomes regarding use of the virtual community of practice. We will calculate a linear mixed-effects regression to estimate the effect of participating in the virtual community of practice. This cluster randomized controlled trial will show whether a virtual intervention for primary healthcare professionals improves attitudes to the empowerment of patients with chronic diseases.

  7. SBARMO, its scientific aims and its organisation

    International Nuclear Information System (INIS)

    Feiter, L.D. de.

    1976-01-01

    SBARMO (Scientific Ballooning and Radiations Monitoring Organisation), known as SPARMO (Solar Particles and Radiations Monitoring Organisation) until 1973, was established in 1961, mainly for the purpose of coordinating balloon-borne measurements of solar energetic particles. The study of auroral X-rays has gradually replaced the study of energetic solar particles as the prime interest of the organisation. The change of name, as adopted during the 1972 Meeting in Graz (Austria) is a logical consequence of the more general orientation of the organisation. The international status of SBARMO is emphasized by its membership of the Federation of Astronomical and Geophysical Services (FAGS) of the International Council of Scientific Unions

  8. Mixed methods research design for pragmatic psychoanalytic studies.

    Tillman, Jane G; Clemence, A Jill; Stevens, Jennifer L

    2011-10-01

    Calls for more rigorous psychoanalytic studies have increased over the past decade. The field has been divided by those who assert that psychoanalysis is properly a hermeneutic endeavor and those who see it as a science. A comparable debate is found in research methodology, where qualitative and quantitative methods have often been seen as occupying orthogonal positions. Recently, Mixed Methods Research (MMR) has emerged as a viable "third community" of research, pursuing a pragmatic approach to research endeavors through integrating qualitative and quantitative procedures in a single study design. Mixed Methods Research designs and the terminology associated with this emerging approach are explained, after which the methodology is explored as a potential integrative approach to a psychoanalytic human science. Both qualitative and quantitative research methods are reviewed, as well as how they may be used in Mixed Methods Research to study complex human phenomena.

  9. Confidentiality in participatory research: Challenges from one study.

    Science.gov (United States)

    Petrova, Elmira; Dewing, Jan; Camilleri, Michelle

    2016-06-01

    This article presents key ethical challenges that were encountered when conducting a participatory qualitative research project with a very specific, small group of nurses, in this case with practice development nurses in Malta. With the small number of nurses employed in practice development roles in Malta, there are numerous difficulties of maintaining confidentiality. Poorly constructed interventions by the researcher could have resulted in detrimental effects to research participants and the overall trustworthiness of the research. Generally, ethical guidelines for research exist to reinforce validity of research; however, there is not an established consensus on how these strategies can be utilised in some types of qualitative field work. The researcher used an exploratory case study methodology. The sample consisted of 10 participants who were interviewed twice using face-to-face interviews, over a period of 2 months. The study was ethically reviewed by the University Research Ethics Committee and the Faculty Research Ethics Committee, University of Malta. The participants referred to in this article have been given adequate information about the study and their consent has been obtained. Numerous strategies for ensuring confidentiality during recruitment of the participants, during data collection, during transcription and data analysis and during dissemination of research results assisted the researcher in responding to potential and actual ethical issues. This article emphasises the main strategies that can be used to respond to ethical challenges when researching with a small easily identifiable group. The learning discussed here may be relevant to or even transferable to other similar research studies or research contexts. These methods fostered a greater credibility throughout the research process and predisposed the participants to greater trust, and thus, they disclosed their experiences and speak more freely, thus enhancing the quality of the study

    To explore the perceptions of physiotherapists towards the use of and participation in research. Concurrent mixed methods research, combining in-depth interviews with three questionnaires (demographics, Edmonton Research Orientation Survey, visual analogue scales for confidence and motivation to participate in research). One physiotherapy department in a rehabilitation hospital, consisting of seven specialised areas. Twenty-five subjects {four men and 21 women, mean age 38 [standard deviation (SD) 11] years} who had been registered as a physiotherapist for a mean period of 15 (SD 10) years participated in this study. They were registered with the New Zealand Board of Physiotherapy, held a current practising certificate, and were working as a physiotherapist or physiotherapy/allied health manager at the hospital. The primary outcome measure was in-depth interviews and the secondary outcome measures were the three questionnaires. Physiotherapists were generally positive towards research, but struggled with the concept of research, the available literature and the time to commit to research. Individual confidence and orientation towards research seemed to influence how these barriers were perceived. This study showed that physiotherapists struggle to implement research in their daily practice and become involved in research. Changing physiotherapists' conceptions of research, making it more accessible and providing dedicated research time could facilitate increased involvement in the physiotherapy profession.

    The effects on the environment of the Chernobyl Power Plant accident, which happened in the reactors unit 4, are analyzed. The aim of the study is to show the main fields of research and development to be considered, in order to improve the knowledge on public or local radiation protection. The following aspects of the problem are discussed: the long range atmospheric transfer, the environment monitoring, the problems related to the food chain transfers, the environment recovery and the estimation of the sanitary effects. The Chernobyl disaster confirms: the priority of special plans of action to protect the surrounding population; that the special plans of action must be followed by after-disaster actions, which take into account methods for the environment recovery; that the conventional systematic approach can not be satisfactorily applied to manage such a critical situation, and a new one must be developed. Moreover, the identification of the most exposed (population) groups, far from the nearby affected area, are to be considered [fr

    2017-08-22

    Neurodegenerative diseases such as Alzheimer's disease (AD), progressive neurodegenerative forms of Huntington's disease, Parkinson's disease (PD), amyotrophic lateral sclerosis, spinal cerebellar ataxias, and spinal and bulbar muscular atrophy are described by slow and selective dysfunction and degeneration of neurons and axons in the central nervous system (CNS). Computer-aided or in silico design methods have matured into powerful tools for reducing the number of ligands that should be screened in experimental assays. In the present review, the authors provide a basic background about neurodegenerative diseases and in silico techniques in the drug research. Furthermore, they review the various in silico studies reported against various targets in neurodegenerative diseases, including homology modeling, molecular docking, virtual high-throughput screening, quantitative structure activity relationship (QSAR), hologram quantitative structure activity relationship (HQSAR), 3D pharmacophore mapping, proteochemometrics modeling (PCM), fingerprints, fragment-based drug discovery, Monte Carlo simulation, molecular dynamic (MD) simulation, quantum-mechanical methods for drug design, support vector machines, and machine learning approaches. Neurodegenerative diseases have a multifactorial pathoetiological origin, so scientists have become persuaded that a multi-target therapeutic strategy aimed at the simultaneous targeting of multiple proteins (and therefore etiologies) involved in the development of a disease is recommended in future.

    Science.gov (United States)

    Flannelly, Kevin J; Jankowski, Katherine R B

    2014-01-01

    This article summarizes the major types of research designs used in healthcare research, including experimental, quasi-experimental, and observational studies. Observational studies are divided into survey studies (descriptive and correlational studies), case-studies and analytic studies, the last of which are commonly used in epidemiology: case-control, retrospective cohort, and prospective cohort studies. Similarities and differences among the research designs are described and the relative strength of evidence they provide is discussed. Emphasis is placed on five criteria for drawing causal inferences that are derived from the writings of the philosopher John Stuart Mill, especially his methods or canons. The application of the criteria to experimentation is explained. Particular attention is given to the degree to which different designs meet the five criteria for making causal inferences. Examples of specific studies that have used various designs in chaplaincy research are provided.

    Anthony, Susan; Jack, Susan

    2009-06-01

    This paper is a report of an integrative review conducted to critically analyse the contemporary use of qualitative case study methodology in nursing research. Increasing complexity in health care and increasing use of case study in nursing research support the need for current examination of this methodology. In 2007, a search for case study research (published 2005-2007) indexed in the CINAHL, MEDLINE, EMBASE, PsychINFO, Sociological Abstracts and SCOPUS databases was conducted. A sample of 42 case study research papers met the inclusion criteria. Whittemore and Knafl's integrative review method guided the analysis. Confusion exists about the name, nature and use of case study. This methodology, including terminology and concepts, is often invisible in qualitative study titles and abstracts. Case study is an exclusive methodology and an adjunct to exploring particular aspects of phenomena under investigation in larger or mixed-methods studies. A high quality of case study exists in nursing research. Judicious selection and diligent application of literature review methods promote the development of nursing science. Case study is becoming entrenched in the nursing research lexicon as a well-accepted methodology for studying phenomena in health and social care, and its growing use warrants continued appraisal to promote nursing knowledge development. Attention to all case study elements, process and publication is important in promoting authenticity, methodological quality and visibility.

  10. Assessing the benefits of OHER (Office of Health and Environmental Research) research: Three case studies

    Nesse, R.J.; Callaway, J.M.; Englin, J.E.; Klan, M.S.; Nicholls, A.K.; Serot, D.E.

    1987-09-01

    This research was undertaken to estimate the societal benefits and costs of selected past research performed for the Office of Health and Environmental Research (OHER) of the US Department of Energy (DOE). Three case studies of representative OHER and DOE research were performed. One of these, the acid rain case study, includes research conducted elsewhere in DOE. The other two cases were the OHER marine research program and the development of high-purity germanium that is used in radiation detectors. The acid rain case study looked at the research benefits and costs of furnace sorbent injection and duct injection, technologies that might reduce acid deposition precursors. Both appear to show benefits in excess of costs. We examined in detail one of the OHER marine research program's accomplishments - the increase in environmental information used by the Outer Continental Shelf leasing program to manage bidding for off-shore oil drilling. The results of an econometric model show that environmental information of the type supported by OHER is unequivocally linked to government and industry leasing decisions. The germanium case study indicated that the benefits of germanium radiation detectors were significant.

  11. Implementation of an Anesthesia Information Management System (AIMS).

    Science.gov (United States)

    Douglas, James R; Ritter, Melody J

    2011-01-01

    During the administration of anesthesia, the anesthesia provider has historically created a paper record, charted manually, that included extensive patient care-related data (vital signs, other parameters, etc) and commentaries. DocuSys, a proprietary anesthesia information management system (AIMS), creates an electronic version of the anesthesia record and provides additional information. It electronically captures data from clinical monitors and other sources, including scheduling applications and laboratory computers. The AIMS facilitates chart entries such as drug doses and case narratives. Benefits of an AIMS include improved legibility of the anesthesia record and greater efficiency in documentation efforts. Use of the AIMS assists the practitioner with decision support logic, such as the timing of antibiotic administration and the inclusion of legally required documentation. Upon case completion, the AIMS data are immediately available to other information systems, such as billing and medical records. Data can be made available from a single case or, more important, from thousands of cases to analyze variables such as efficiency of services, adherence to best practices, patient outcomes, and clinical research. The AIMS was deployed at the main campus of the Ochsner Health System on March 26, 2009. In this article, we discuss the issues involved in the AIMS implementation process: the successes, surprises, and continued challenges.

    Family-based interventions to prevent childhood obesity depend upon parents' taking action to improve diet and other lifestyle behaviours in their families. Programmes that attract and retain high numbers of parents provide an enhanced opportunity to improve public health and are also likely to be more cost-effective than those that do not. We have developed a theory-informed optimisation intervention to promote parent engagement within an existing childhood obesity prevention group programme, HENRY (Health Exercise Nutrition for the Really Young). Here, we describe a proposal to evaluate the effectiveness of this optimisation intervention in regard to the engagement of parents and cost-effectiveness. The Optimising Family Engagement in HENRY (OFTEN) trial is a cluster randomised controlled trial being conducted across 24 local authorities (approximately 144 children's centres) which currently deliver HENRY programmes. The primary outcome will be parental enrolment and attendance at the HENRY programme, assessed using routinely collected process data. Cost-effectiveness will be presented in terms of primary outcomes using acceptability curves and through eliciting the willingness to pay for the optimisation from HENRY commissioners. Secondary outcomes include the longitudinal impact of the optimisation, parent-reported infant intake of fruits and vegetables (as a proxy to compliance) and other parent-reported family habits and lifestyle. This innovative trial will provide evidence on the implementation of a theory-informed optimisation intervention to promote parent engagement in HENRY, a community-based childhood obesity prevention programme. The findings will be generalisable to other interventions delivered to parents in other community-based environments. This research meets the expressed needs of commissioners, children's centres and parents to optimise the potential impact that HENRY has on obesity prevention.

    To compare the inclusion and the influences of selected variables on hypothesis testing during the 1980s and 1990s. In spite of the emphasis on conducting inquiry consistent with the tenets of logical positivism, there have been no studies investigating the frequency and patterns of hypothesis testing in nursing research The sample was obtained from the journal Nursing Research which was the research journal with the highest circulation during the study period under study. All quantitative studies published during the two decades including briefs and historical studies were included in the analyses A retrospective design was used to select the sample. Five years from the 1980s and 1990s each were randomly selected from the journal, Nursing Research. Of the 582 studies, 517 met inclusion criteria. Findings suggest that there has been a decline in the use of hypothesis testing in the last decades of the 20th century. Further research is needed to identify the factors that influence the conduction of research with hypothesis testing. Hypothesis testing in nursing research showed a steady decline from the 1980s to 1990s. Research purposes of explanation, and prediction/ control increased the likelihood of hypothesis testing. Hypothesis testing strengthens the quality of the quantitative studies, increases the generality of findings and provides dependable knowledge. This is particularly true for quantitative studies that aim to explore, explain and predict/control phenomena and/or test theories. The findings also have implications for doctoral programmes, research preparation of nurse-investigators, and theory testing.

  14. An overview of industrial and organisational psychology research in South Africa: A preliminary study

    Research purpose: The purpose of this study was to explore general research trends in the field of industrial and organisational psychology in South Africa from 1950 to 2008. Motivation for study: Research in the field tends to be influenced by either the changing needs of business or the occupational or personal fields of interest of academics, which often lead to an overemphasis on specific subdisciplines at the expense of others. This research aims to critically review dominant trends in the research focus areas in the field, in the light of present challenges in the changing work context. Recommendations are also made for possible future research. Research design, approach and method: A broad systematic review was carried out to analyse documented published and accredited South African research in the field (n = 2501. Main findings: Although there has been a proportional decline in personnel psychology research since 1990, there has been a proportional increase in both organisational psychology and employee wellness research since 1980 and 1990, respectively. Some areas of the industrial and organisational psychology field appear to be consistently under-researched. Practical implications: The insights derived from the findings can be used by academia and researchers in the field to plan future research initiatives. Contribution/value-add: The findings provide preliminary insights that contribute to the body of knowledge concerned with the industrial and organisational psychology field in the South African context.

  15. An ethnographic study of nurses' experience with nursing research and its integration in practice.

    To report from a study aimed at illuminating how French Registered Nurses experience and engage in nursing research in clinical practice. Nursing research in France is mainly conducted by nurses working at clinical research units rather than by dedicated nurse researchers. Education, i.e. advanced degrees, in the field of nursing research is still in its infancy and not yet consistent with the international context. Outside France, the general perception is that nursing research is a unified part of professional nursing. Consequently, in-depth knowledge about how nurses in a French clinical context might experience and engage in nursing research is still lacking. The design of this study was influenced by an ethnographic approach as described by the French anthropologists Beaud and Weber. Data, participatory observations, field notes and interviews (n = 6) were collected in a teaching hospital between April-August 2012. The field consisted of a wound-care unit and clinical research units. Collected data were analysed based on Beaud and Weber's description of analysis. Three beliefs were identified: being a unified part of a research team, being an integral part of 'crosswise - across' activities and being part of research activities. Commitment to nursing research was strengthened by patient-related issues. Based on this context, nursing research would likely benefit from the support of a naturalized reciprocity between clinical practice and research. © 2014 John Wiley & Sons Ltd.

    Traditionally, the literature on action research has been aimed at intra-organisational issues. These studies have distinguished between two researcher roles: The problem-solver and the observer. This article addresses the distinct challenges of action research in inter-organisational projects....... In addition to the problem-solver and observer roles, the researcher in an inter-organisational setting can serve as a legitimiser of the project and manage to involve partners that in an ordinary business-to-business setting would not have participated.

    During 1983-84, Xerox Corporation was undergoing a change in corporate style through a process of training and altered behavior known as Leadership Through Quality. One tenet of Leadership Through Quality was benchmarking, a procedure whereby all units of the corporation were asked to compare their operation with the outside world. As a part of the first wave of benchmark studies, Xerox Corporate Research Group studied the processes of research management, technology transfer, and research planning in twelve American and Japanese companies. The approach taken was to separate `research yield' and `research productivity' (as defined by Richard Foster) and to seek information about how these companies sought to achieve high- quality results in these two parameters. The most significant findings include the influence of company culture, two different possible research missions (an innovation resource and an information resource), and the importance of systematic personal interaction between sources and targets of technology transfer.

    The rate of manifestation of spinal lipoma (SL) is essentially unknown and propriety of its treatment is still controversial. Started in 2006 a prospective study by 7 facilities (COE-SB Top 7) to elucidate the natural history by such a mean as seeing the age distribution in SL manifestation, and to find applicable factors for conducting prophylactic surgery by such evaluation as improvable symptoms and surgical complication. Facilities also retrospectively summarized their outcomes of surgery and of conservative follow-up in the past 5 years. Further, evaluated was the usefulness of neuroendoscopic observation and assistance in diagnosis and operation, because diagnosis for predicting the neurological prognosis is often difficult by preoperative MRI alone and is changeable by surgical findings due to complex SL structures. This paper is a report describing tentative results of the prospective study above in the first 1 year, of the retrospective one and of the endoscopic utility. Subjects were 45 patients (21 cases, <1 year after birth; asymptomatic, 29 and symptomatic, 16) in the prospective study and 261 patients (asymptomatic, 159 and symptomatic, 102) in the retrospective. The endoscope used was an Oi-Samii Handy Pro type. Neurological symptom was assessed by Spina Befida Neurological Scale (1992). Patients were classified according to Embryo-pathogenetic and Surgico-anatomical Classification of Spina Bifida (2002). Results were: the prevalence was 15% at birth and increased afterwards; prognosis post surgery was poor in transitional SL; symptomatic improvement by operation was small; operative complication was scarce; and endoscope was conceivably useful for diagnosis and operative assistance.

    Cancer pain is a common, burdensome problem, which is not well managed despite evidence-based guidelines. To develop insights for managing barriers and optimizing facilitators to adult cancer pain assessment and management within a comprehensive framework of patient care. We undertook a systematic review and synthesis of qualitative studies. Medline, PsycINFO, Embase, AMED, CINAHL, and Sociological Abstracts were searched from May 20 to 26, 2011. To be included, the articles had to be published in a peer-reviewed journal since 2000; written in English; and report original qualitative studies on the perspectives of patients, their significant others, or health care providers. Article quality was rated using the checklist of Kitto et al. Thematic synthesis followed a three-stage approach using Evidence for Policy and Practice Information and Co-ordinating Centre-Reviewer 4 software: 1) free line-by-line coding of "Results," 2) organization into "descriptive" themes, and 3) development of "analytical" themes informative to our objective. At Stage 3, a conceptual framework was selected from the peer-reviewed literature according to prima facie "fit" for descriptive themes. Of 659 articles screened, 70 met the criteria, reporting 65 studies with 48 patient, 19 caregiver, and 21 health care provider samples. Authors rarely reported reflexivity or negative cases. Mead and Bower's model of patient-centered care accommodated 85% of the descriptive themes; 12% more related to the caregiver and service/system factors. Three themes could not be accommodated. Findings highlight the need to integrate patient/family education within improved communication, individualize care, use more nonpharmacological strategies, empower patients/families to self-manage pain, and reorganize multidisciplinary roles around patient-centered care and outcomes. These conclusions require validation via consensus and intervention trials. Copyright © 2013 U.S. Cancer Pain Relief Committee. Published

    Contemporary emphasis on creating culturally relevant and context specific knowledge increasingly drives researchers to conduct their work in settings outside their home country. This often requires researchers to build relationships with various stakeholders who may have a vested interest in the research. This case study examines the tension between relationship development with stakeholders and maintaining study integrity, in the context of potential harms, data credibility and cultural sensitivity. We describe an ethical breach in the conduct of global health research by a arising from the ad-hoc participation of a community stakeholder external to the visiting research group. A framework for reflection is developed from a careful examination of underlying factors and presented with a discussion of consequences and mitigation measures. This framework aims to present lessons learned for researchers working abroad who might face similar situations in their work. © 2015 John Wiley & Sons Ltd.

    This work addresses the characterization of physical, chemical and mechanical properties of steel slag as an alternative aggregation before and after leaching testing controlled Soxhlet extractor. The material it was characterized before going through the natural leaching process and after controlled leaching in different periods of 24, 56, 96, 120 hours. The steel slag was subjected in the laboratory to simulate the precipitation in Soxhlet equipment to evaluate its physical, chemical and mechanical properties after each period described. The study of the process of leaching in steel slag searched to understand the influence of the washing process in a slag behavior in such a process. The physical characterization occurred through traditional testing of coarse aggregates, the chemical characterization through the testing of Scanning Electron Microscopy (SEM) completed by Dispersive Spectroscopy Energy (DSE) and X- ray diffraction and the mechanical characterization through testing of standardized expansion and adapted. The sample virgin, without receiving process of stabilization by controlled leaching, showed satisfactory results in the physics characterization when compared to conventional aggregates, the chemical characterization proved to be a steel slag with high contents of CaO, MgO and FeO, the mechanical characterization demonstrated that, although the degree of expansibility of the slag is low demonstrated that this should not be disregarded in the paving work. After controlled leaching the steel slag showed no significant loss of its physical properties. As the mechanical testing of expansion had decreased the potential of expansibility after leaching periods. It is concluded that the leaching process in a Soxhlet extractor is of importance in the study the properties of steel slag, once covering several days of leaching was reduced potential for expansion, limiting feature in the use of steel slag for paving.

Difficulties in recruitment are not uncommon and can have important implications. This is particularly relevant to research conducted in affective disorders due to the nature of the conditions and the clinical services that serve these patients. Recently, online public advertisements have become more generally accessible and may provide an effective way to recruit patient populations. However, there is paucity of evidence on their viability as a method of recruiting patients into studies of disease mechanisms in these disorders. Public advertisement methods can be useful when researchers require specific populations, such as those not receiving pharmacological treatment. This work describes our experience in successfully recruiting participants into neuroimaging research studies in affective disorders using online public advertisements. Results suggest that these online public advertisements are an effective method for successfully recruiting participants with affective disorders into research studies, particularly for research focusing on disease mechanisms in specific populations.

    The hydrogen, utilized in fuel cells, can be produced from a variety of intermediate chemicals, between them, the ammonia. The ammonia gas as a raw material for the hydrogen production has been used due to its high energetic content, facility of decomposition, high availability, low prices, low storage pressure and its by-products are environmentally correct. One of the sources of ammonia is poultry and egg production systems. In these systems the ammonia is produced from the decomposition of uric acid present in the excreta of birds. The residue from the poultry-rearing farms is the broiler litter and from the egg production system is the excreta without any substrate. The characterization of these residues was performed using the wavelength-dispersive X-ray fluorescence (WDXRF), elementary analysis (CHN), thermogravimetry and GC/MS - gas chromatography/ mass spectrometry. The studied factors which influence the ammonia volatilization were: nitrogen content, raising period, urease enzyme, temperature, pH and moisture content. The experiment results with poultry litter and excreta allow to conclude that the manipulation of the following parameters increased the ammonia emission: pH, nitrogen content, raising period, age of birds and excreta accumulation, urease enzyme and the temperature. The addition of different amounts of sand in the excreta and different volumes of water in the poultry litter inhibited the emission of ammonia. The variation of the quantity of material (broiler litter or excreta) and the volume of the flask used as incubator chamber showed no significant alterations to be chosen as a variable. The excreta was considered more appropriate than poultry litter for the objectives of this work due to the higher ammonia concentrations determined in this material. Due to the large amount of poultry litter and excreta from the production processes, the reuse of poultry residues to obtain ammonia is necessary to improve the quality of the local

    Maternal and perinatal mortality continue to be a high priority problem on the health agendas of less developed countries. Despite the progress made in the last decade to quantify the magnitude of maternal mortality, few interventions have been implemented with the intent to measure impact directly on maternal or perinatal deaths. The success of interventions implemented in less developed countries to reduce mortality has been questioned, in terms of the tendency to maintain a clinical perspective with a focus on purely medical care separate from community-based approaches that take cultural and social aspects of maternal and perinatal deaths into account. Our innovative approach utilizes both the clinical and community perspectives; moreover, our study will report the weight that each of these components may have had on reducing perinatal mortality and increasing institution-based deliveries. A matched pair cluster-randomized trial will be conducted in clinics in four rural indigenous districts with the highest maternal mortality ratios in Guatemala. The individual clinic will serve as the unit of randomization, with 15 matched pairs of control and intervention clinics composing the final sample. Three interventions will be implemented in indigenous, rural and poor populations: a simulation training program for emergency obstetric and perinatal care, increased participation of the professional midwife in strengthening the link between traditional birth attendants (TBA) and the formal health care system, and a social marketing campaign to promote institution-based deliveries. No external intervention is planned for control clinics, although enhanced monitoring, surveillance and data collection will occur throughout the study in all clinics throughout the four districts. All obstetric events occurring in any of the participating health facilities and districts during the 18 months implementation period will be included in the analysis, controlling for the cluster

    Full Text Available This article approaches the historical development of the field of migratory studies in Argentina and makes a review of the academic production around the so - called "migratory policies." The systematization of these studies, historically placed on migration policies, aims to highlight some of the most significant contributions of the research during the last 30 years, to understand or explain various aspects and dimensions of the Argentinean migration policy. To achieve this, texts were selected that derived from empirical research that explicitly assume the migratory policies as the object of study, or whose themes and research problems adopt as a framework for discussion the policies and practices aimed at regulating migration and mobility in Argentina. The organization and presentation of these selected texts consider issues related to the interests and thematic concerns, disciplinary and analytical approaches, distinct periods, scales of analysis and sources of information.

    The polyacrylamide is one of the main polymers used in the petroleum industry. Among its properties, stands out the capacity to alter the permeability of the rock to water. However, the polyacrylamide presents some limitations, such as low tolerance to the presence of salts, what can promote its precipitation resulting in low oil recovery efficiency. The application of the polymer in emulsion can promote a larger stability, due to the presence of a surfactant, which has the capacity to modify the interfacial tension and to form a film between the phases of the emulsion. Thereby, the injection of a polymer emulsion can promote an increase of oil recovery. In this work, a preliminary study of the effect of a anionic surfactant (SDS) and polyacrylamides (anionic and neutral) on the surface tension and rheology is presented in aqueous solutions contend salt (NaCl). The results showed surface tension of the mixtures had been remained constant and low (around 32 mN/m), independent of the polymer concentration. A viscosity reduction was observed at polymeric solutions as much in presence of salt, as in presence of the surfactant. Both the samples showed a pseudo plastic behavior. (author)

    The oxime derived from 6-acetyl-1,3,7-trimethyllumazine (1) ((E-6-(hydroxyimino)ethyl)-1,3,7-trimethylpteridine-2,4(1H,3H)-dione, DLMAceMox) has been prepared and its molecular and crystal structure determined from spectral and XRD data. The oxime ligand was reacted with silver nitrate, perchlorate, thiocyanate, trifluoromethylsulfonate and tetrafluoroborate to give complexes with formulas [Ag(2)(DLMAceMox)(2)(NO(3))(2)](n) (2), [Ag(2)(DLMAceMox)(2)(ClO(4))(2)](n) (3), [Ag(2)(DLMAceMox)(2)(SCN)(2)] (4), [Ag(2)(DLMAceMox)(2)(CF(3)SO(3))(2)(CH(3)CH(2)OH)]·CH(3)CH(2)OH (5) and [Ag(DLMAceMox)(2)]BF(4) (6). Single-crystal XRD studies show that the asymmetrical residual unit of complexes 2, 3 and 5 contains two quite different but connected silver centers (Ag1-Ag2, 2.9-3.2 Å). In addition to this, the Ag1 ion displays coordination with the N5 and O4 atoms from both lumazine moieties and a ligand (nitrato, perchlorato or ethanol) bridging to another disilver unit. The Ag2 ion is coordinated to the N61 oxime nitrogens, a monodentate and a (O,O)-bridging nitrato/perchlorato or two monodentate O-trifluoromethylsulfonato anions. The coordination polyhedra can be best described as a strongly distorted octahedron (around Ag1) and a square-based pyramid (around Ag2). The Ag-N and Ag-O bond lengths range between 2.22-2.41 and 2.40-2.67 Å, respectively. Although the structure of 4 cannot be resolved by XRD, it is likely to be similar to those described for 2, 3 and 5, containing Ag-Ag units with S-thiocyanato terminal ligands. Finally, the structure of the tetrafluoroborate compound 6 is mononuclear with a strongly distorted tetrahedral AgN(4) core (Ag-N, 2.27-2.43 Å). Always, the different Ag-N distances found clearly point to the more basic character of the oxime N61 nitrogen atom when compared with the pyrazine N5 one.

    Our purpose is to identify a computational level sufficiently dependable and affordable to assess trends in the interaction of a variety of radical or closed shell unsaturated hydro-carbons A adsorbed on soot platelet models B. These systems, of environmental interest, would unavoidably have rather large sizes, thus prompting to explore in this paper the performances of relatively low-level computational methods and compare them with higher-level reference results. To this end, the interaction of three complexes between non-polar species, vinyl radical, ethyne, or ethene (A) with benzene (B) is studied, since these species, involved themselves in growth processes of polycyclic aromatic hydrocarbons (PAHs) and soot particles, are small enough to allow high-level reference calculations of the interaction energy ΔEAB. Counterpoise-corrected interaction energies ΔEAB are used at all stages. (1) Density Functional Theory (DFT) unconstrained optimizations of the A-B complexes are carried out, using the B3LYP-D, ωB97X-D, and M06-2X functionals, with six basis sets: 6-31G(d), 6-311 (2d,p), and 6-311++G(3df,3pd); aug-cc-pVDZ and aug-cc-pVTZ; N07T. (2) Then, unconstrained optimizations by Møller-Plesset second order Perturbation Theory (MP2), with each basis set, allow subsequent single point Coupled Cluster Singles Doubles and perturbative estimate of the Triples energy computations with the same basis sets [CCSD(T)//MP2]. (3) Based on an additivity assumption of (i) the estimated MP2 energy at the complete basis set limit [EMP2/CBS] and (ii) the higher-order correlation energy effects in passing from MP2 to CCSD(T) at the aug-cc-pVTZ basis set, ΔECC-MP, a CCSD(T)/CBS estimate is obtained and taken as a computational energy reference. At DFT, variations in ΔEAB with basis set are not large for the title molecules, and the three functionals perform rather satisfactorily even with rather small basis sets [6-31G(d) and N07T], exhibiting deviation from the computational

  7. Motivation, procedures and aims of reacting plasma experiments

    International Nuclear Information System (INIS)

    Miyahara, Akira

    1982-01-01

    A project of reacting plasma experiment (R-project) was proposed at the Institute of Plasma Physics (IPP), Nagoya University. It is necessary to bridge plasma physics and fusion engineering by means of a messenger wire like burning plasma experiment. This is a motivation of the R-project. The university linkage organization of Japan for fusion engineering category carried out a lot of contribution to R-tokamak design. The project consists of four items, namely, R-tokamak design, research and development (R and D), site and facilities, and international collaboration. The phase 1 experiment (R 1 - phase) corresponds to burning plasma experiment without D + T fuel, while the phase-2 experiment (R 2 -phase) with D + T fuel. One reference design was finished. Intensive efforts have been carried out by the R and D team on the following items, wall material, vacuum system, tritium system, neutronics, remote control system, pulsed superconducting magnet development, negative ion source, and alpha-particle diagnostics. The problems concerning site and major facilities are also important, because tritium handling, neutron and gamma-ray sky shines and the activation of devices cause impact to surrounding area. The aims of burning plasma experiment are to enter tritium into the fusion device, and to study burning plasma physics. (Kato, T.)

  13. Mutual research capacity strengthening: a qualitative study of two-way partnerships in public health research

    2012-12-01

    Full Text Available Abstract Introduction Capacity building has been employed in international health and development sectors to describe the process of ‘experts’ from more resourced countries training people in less resourced countries. Hence the concept has an implicit power imbalance based on ‘expert’ knowledge. In 2011, a health research strengthening workshop was undertaken at Atoifi Adventist Hospital, Solomon Islands to further strengthen research skills of the Hospital and College of Nursing staff and East Kwaio community leaders through partnering in practical research projects. The workshop was based on participatory research frameworks underpinned by decolonising methodologies, which sought to challenge historical power imbalances and inequities. Our research question was, “Is research capacity strengthening a two-way process?” Methods In this qualitative study, five Solomon Islanders and five Australians each responded to four open-ended questions about their experience of the research capacity strengthening workshop and activities: five chose face to face interview, five chose to provide written responses. Written responses and interview transcripts were inductively analysed in NVivo 9. Results Six major themes emerged. These were: Respectful relationships; Increased knowledge and experience with research process; Participation at all stages in the research process; Contribution to public health action; Support and sustain research opportunities; and Managing challenges of capacity strengthening. All researchers identified benefits for themselves, their institution and/or community, regardless of their role or country of origin, indicating that the capacity strengthening had been a two-way process. Conclusions The flexible and responsive process we used to strengthen research capacity was identified as mutually beneficial. Using community-based participatory frameworks underpinned by decolonising methodologies is assisting to redress

    The Mizunami Underground Research Laboratory (MIU) of the Japan Atomic Energy Agency is a major site for geoscientific research to advance the scientific and technological basis for geological disposal of high-level radioactive waste in crystalline rock. Studies on relevant engineering technologies in the MIU consist of a) research on design and construction technology for very deep underground applications, and b) research on engineering technology as a basis of geological disposal. In the Second Phase of the MIU project (the construction phase), engineering studies have focused on research into design and construction technologies for deep underground. The main subjects in the study of very deep underground structures consist of the following: 'Demonstration of the design methodology', 'Demonstration of existing and supplementary excavation methods', 'Demonstration of countermeasures during excavation' and 'Demonstration of safe construction'. In the FY 2007 studies, identification and evaluation of the subjects for study of engineering technologies in the construction phase were carried out to optimize future research work. Specific studies included: validation of the existing design methodology based on data obtained during construction; validation of existing and supplementary rock excavation methods for very deep shafts; estimation of rock stability under high differential water pressures, methodology on long-term maintenance of underground excavations and risk management systems for construction of underground structures have been performed. Based on these studies, future research focused on the four subject areas, which are 'Demonstration of the design methodology', 'Demonstration of existing and supplementary excavation methods', 'Demonstration of countermeasures during excavation' and 'Demonstration of safe construction', has been identified. The design methodology in the first phase of the MIU Project (surface-based investigation phase) was verified to

    The initial approach used in establishing a user-defined information system to fulfill the needs of users at NASA Headquarters was unsuccessful in bringing this pilot endeaveor to full project status. The persistence of several users and the full involvement of the Ames Research Center were the ingredients needed to make the AIMS project a success. The lesson learned from this effort is that NASA should always work from its organizational strengths as a Headquarters-Center partnership.

    Full Text Available Introduction: Aging of the population and early retirement translates into productivity losses to society. Persistence of working life is crucial to counteract this sustainability issue faced by western countries. Musculoskeletal and rheumatic diseases (RD may cause work disability and early exit from work, including early retirement. The objective of this article is to review the current knowledge about interventions aiming to reduce early retirement due to RD. Methods: We searched PubMed and The Cochrane Library for studies either in English or Portuguese between January 2000 and June 2016 that evaluated the impact of interventions targeting early retirement in RD patients still at work. We also searched for grey literature from Portuguese institutional repositories. Results: We identified several published studies testing pharmacologic and non-pharmacologic vocational rehabilitation interventions. None was specifically identified for Portugal. The general low quality of the literature and its inconsistency makes it unfeasible to draw definitive conclusions. However, some broad recommendations might be outlined. An effective intervention must: 1 act upon different levels (e.g. RD patient, workplace, involving several stakeholders (e.g. rheumatologists, occupational physicians, employers; 2 prioritize the right patients (e.g. more disabling RD; and 3 consider the patients’ role, for instance by including an element of patient education and support. Despite the lack of good quality evidence on this field, there seems to be a growing interest in the international scientific community with several ongoing studies promoting such interventions. This promising data will be very useful to set up effective policies. Conclusions: This article summarizes the current knowledge about the impact of interventions to avoid or mitigate early retirement in RD patients. It highlights the demand for further research and it also contributes to aware decision

    Increasing the number of patients participating in research studies is a current priority in the National Health Service (NHS) in the United Kingdom. The role of specialist nurses in inviting patients to participate is important, yet little is known about their experiences of doing so. The aim of this study was to explore the perceptions of barriers and facilitators held by specialist nurses with experience of inviting adult NHS patients to a wide variety of research studies. A cross-sectional qualitative descriptive study was conducted between March and July 2015. Participants were 12 specialist nurses representing 7 different clinical specialties and 7 different NHS Trusts. We collected data using individual semi-structured interviews, and analysed transcripts using the Framework method to inductively gain a descriptive overview of barriers and facilitators. Barriers and facilitators were complex and interdependent. Perceptions varied among individuals, however barriers and facilitators centred on five main themes: i) assessing patient suitability, ii) teamwork, iii) valuing research, iv) the invitation process and v) understanding the study. Facilitators to inviting patients to participate in research often stemmed from specialist nurses' attitudes, skills and experience. Positive research cultures, effective teamwork and strong relationships between research and clinical teams at the local clinical team level were similarly important. Barriers were reported when specialist nurses felt they were providing patients with insufficient information during the invitation process, and when specialist nurses felt they did not understand studies to their satisfaction. Our study offers several new insights regarding the role of specialist nurses in recruiting patients for research. It shows that strong local research culture and teamwork overcome some wider organisational and workload barriers reported in previous studies. In addition, and in contrast to common practice

    In many ways, the Advanced Industrial Materials (AIM) Program underwent a major transformation in Fiscal Year 1995 and these changes have continued to the present. When the Program was established in 1990 as the Advanced Industrial Concepts (AIC) Materials Program, the mission was to conduct applied research and development to bring materials and processing technologies from the knowledge derived from basic research to the maturity required for the end use sectors for commercialization. In 1995, the Office of Industrial Technologies (OIT) made radical changes in structure and procedures. All technology development was directed toward the seven ``Vision Industries`` that use about 80% of industrial energy and generated about 90% of industrial wastes. The mission of AIM has, therefore, changed to ``Support development and commercialization of new or improved materials to improve productivity, product quality, and energy efficiency in the major process industries.`` Though AIM remains essentially a National Laboratory Program, it is essential that each project have industrial partners, including suppliers to, and customers of, the seven industries. Now, well into FY 1996, the transition is nearly complete and the AIM Program remains reasonably healthy and productive, thanks to the superb investigators and Laboratory Program Managers. This Annual Report for FY 1995 contains the technical details of some very remarkable work by the best materials scientists and engineers in the world. Areas covered here are: advanced metals and composites; advanced ceramics and composites; polymers and biobased materials; and new materials and processes.

    With efficient use of energy, renewable energy sources can supply the majority, if not the totality, of energy supplies in developed nations at real energy prices that double or triple by 2025 (1975 prices). This appears true even in harsh climates with oil dependent industrial economies. Large increases in end-use energy efficiency are cost effective at present prices. Some reports show that cost effective end-use efficiency improvements can reduce energy consumption (per capita, per unit of amenity, or per unit of output) to as much as 90 percent. This was demonstrated by highly disaggregated analyses of end-uses. Such analyses consistently show larger potential for efficiency improvements than can be detected from conventional analyses of more aggregated data. As energy use demands decline due to end use efficiency improvements, energy supply problems subsequently decrease. Lifestyle changes, influenced by social factors, and rising energy prices can substantially reduce demands for energy. Such changes are already discernible in end-use energy studies. When energy efficient capital stock is in place, many end-users of energy will be able to provide a substantial portion of their own energy needs from renewable energy sources that are directly available to them.

    Currently, there are a number of institutional problems associated with the shipment of spent fuel assemblies from commercial nuclear power plants: new and conflicting regulations, embargoing of certain routes, imposition of transport safeguards, physical security in-transit, and a lack of definition of when and where the fuel will be moved. This report presents a summary of these types and kinds of problems. It represents the results of evaluations performed relative to fuel receipt at the Barnwell Nuclear Fuel Plant. Case studies were made which address existing reactor sites with near-term spent fuel transportation needs. Shipment by either highway, rail, water, or intermodal water-rail was considered. The report identifies the impact of new regulations and uncertainty caused by indeterminate regulatory policy and lack of action on spent fuel acceptance and storage. This stagnant situation has made it impossible for industry to determine realistic transportation scenarios for business planning and financial risk analysis. A current lack of private investment in nuclear transportation equipment is expected to further prolong the problems associated with nuclear spent fuel and waste disposition. These problems are expected to intensify in the 1980's and in certain cases will make continuing reactor plant operation difficult or impossible

    The next generation reactors represented in ABWR-II should enhance not only economics but also safety. Especially, the ideal target of 'No Evacuation', that is, no FP (Fission Product) release in severe accidents should be required. This paper provides the conceptual design achieving 'No Evacuation' by using only the passive systems, that are, the passive containment cooling system (PCCS), the large amount of water inside containment, outside pool by utilizing gap between containment and surrounding building, and the natural heat removal from the containment surface to atmosphere. Furthermore, it is also easy to adopt the countermeasure for airplane crash by using a dome shelter and the dispersed layout as an option. At the same time, the amount of the construction material of this concept is competitive comparing with that of the conventional BWR because it is easy to use the steel structure or the steel plate reinforced concrete structure over a wide area.

    Background Qualitative research is undertaken with randomized controlled trials of health interventions. Our aim was to explore the perceptions of researchers with experience of this endeavour to understand the added value of qualitative research to the trial in practice. Methods A telephone semi-structured interview study with 18 researchers with experience of undertaking the trial and/or the qualitative research. Results Interviewees described the added value of qualitative research for the trial, explaining how it solved problems at the pretrial stage, explained findings, and helped to increase the utility of the evidence generated by the trial. From the interviews, we identified three models of relationship of the qualitative research to the trial. In ‘the peripheral’ model, the trial was an opportunity to undertake qualitative research, with no intention that it would add value to the trial. In ‘the add-on’ model, the qualitative researcher understood the potential value of the qualitative research but it was viewed as a separate and complementary endeavour by the trial lead investigator and wider team. Interviewees described how this could limit the value of the qualitative research to the trial. Finally ‘the integral’ model played out in two ways. In ‘integral-in-theory’ studies, the lead investigator viewed the qualitative research as essential to the trial. However, in practice the qualitative research was under-resourced relative to the trial, potentially limiting its ability to add value to the trial. In ‘integral-in-practice’ studies, interviewees described how the qualitative research was planned from the beginning of the study, senior qualitative expertise was on the team from beginning to end, and staff and time were dedicated to the qualitative research.

    Full Text Available The learning of English as a foreign language is an additional burden for art majors. This study aimed to examine high frequency words in art research articles to improve the efficiency of art majors’ English learning, especially their academic reading and writing. For this aim, the study built a corpus, analyzed data from art research articles and compared data with three base word lists. We found that the General Service List (GSL and the Academic Word List (AWL had a high coverage in our corpus, and there was a different high frequency word order in the Art Research Article Corpus (ARAC. These findings provide some implications for teaching English for art majors.

    Full Text Available Abstract: Researchers often encounter dangerous situations while conducting social research. The concept of risk to researchers refers to the possible harm that may occur to researchers while in the field or after leaving a research project. This study explores issues experienced by social scientists engaged in research on social deviance or criminal behavior. The goal of this research was to discover the types of risk experienced by social scientists and any mediating factors affecting the experience of risk. An online survey was conducted to gather data on issues experienced by social scientists. This study found that researchers experienced a variety of risks within the categories of physical/health, emotional, legal, and personal/professional. Each of the survey options for risk were reported by at least one respondent; however, the greatest number of risks reported were of an emotional or personal/professional nature. There were no mediating factors found to be significant in relation to the experience of risk. This was a surprising finding especially for the variable of gender as it is suggested that gender plays a role in the experience of difficulties.

  11. THE BASIC PRINCIPLES OF RESEARCH IN NEUROEDUCATION STUDIES

    2016-06-01

    Full Text Available The present paper assembles contributions from the areas of education, psychology, cognitive science, and of course, neuroeducation itself to introduce the basic principles of research in the field of neuroeducation studies. It is particularly important, as such it is a useful way to justify researchers about what neuroeducation as a specific domain do that no other field can do as well or cannot do at all. Based on the literature reviewed, neuroeducational research can be understood as an interdisciplinary endeavor to develop an insightful understanding and holistic picture of problems related to learning and education. It thus epistemologically is based on an integrated methodological pluralism paradigm. This requires researchers to understand multiple methods and methodologies and employ as they formulate their own research projects. Researchers have a critical role to play in providing systematic evidence and conclusions that are scientifically valid and reliable and educationally relevant and usable. One significant implication of this argument is the need to strengthen the quality of the research component in graduate programs of the field and train interested researchers in the identification and formulation of relevant research questions.

    The aim of this study was to describe nurse leaders' perceptions of ethical recruitment in clinical research. Nurse leaders are expected to get involved in clinical research, but there are few studies that focus on their role, particularly the ethical issues. Qualitative data were collected from ten nurse leaders using thematic one-to-one interviews and analysed with content analysis. Nurse leaders considered clinical research at their workplace in relation to the key issues that enabled ethical recruitment of study subjects in clinical research. These were: early information and collaboration for incorporating clinical research in everyday work, an opportune and peaceful recruitment moment and positive research culture. Getting involved in clinical research is part of the nurse leader's professional responsibility in current health care. They have an essential role to play in ensuring that recruitment is ethical and that the dignity of study subjects is maintained. The duty of nurse leaders is to maintain good contact with other collaborators and to ensure good conditions for implementing clinical research at their site. This requires a comprehensive understanding of the overall situation on their wards. Implementing clinical research requires careful planning, together with educating, supporting and motivating nursing staff. © 2014 John Wiley & Sons Ltd.

    Full Text Available National cultures and cultural differences provide a crucial component of the international business (IB research context. We conducted a bibliometric study of articles published in seven leading IB journals over a period of three decades to analyze how national culture has been impacting IB research. Co-citation mappings permit us to identify the ties binding works dealing with culture and cultural issues in IB. We identify two main clusters of research, each comprising two sub-clusters, with Hofstede’s (1980 work delineating much of the conceptual and empirical approach to culture-related studies. One main cluster entails works on the conceptualization of culture and its dimensions and the other cluster focuses on cultural distance. This conceptual framework captures the extant IB research incorporating culture-related concepts and influences.
