    A 15-Country collaborative cohort study was conducted to provide direct estimates of cancer risk following protracted low doses of ionizing radiation. Analyses included 407,391 nuclear industry workers monitored individually for external radiation and 5.2 million person-years of follow-up. A significant association was seen between radiation dose and all-cause mortality [excess relative risk (ERR) 0.42 per Sv, 90% CI 0.07, 0.79; 18,993 deaths]. This was mainly attributable to a dose-related increase in all cancer mortality (ERR/Sv 0.97, 90% CI 0.28, 1.77; 5233 deaths). Among 31 specific types of malignancies studied, a significant association was found for lung cancer (ERR/Sv 1.86, 90% CI 0.49, 3.63; 1457 deaths) and a borderline significant (P = 0.06) association for multiple myeloma (ERR/Sv 6.15, 90% CI risk estimates.

    ionizing radiation dose within the 15-country nuclear workers cohort study. The analyses included, in seven countries with CLL deaths, a total of 295,963 workers with more than 4.5 million person-years of follow-up and an average cumulative bone marrow dose of 15 mSv; there were 65 CLL deaths...... in this cohort. The relative risk (RR) at an occupational dose of 100 mSv compared to 0 mSv was 0.84 (95% CI 0.39, 1.48) under the assumption of a 10-year exposure lag. Analyses of longer lag periods showed little variation in the RR, but they included very small numbers of cases with relatively high doses....... In conclusion, the largest nuclear workers cohort study to date finds little evidence for an association between low doses of external ionizing radiation and CLL mortality. This study had little power due to low doses, short follow-up periods, and uncertainties in CLL ascertainment from death certificates...

  5. Incomplete data on the Canadian cohort may have affected the results of the study by the International Agency for Research on Cancer on the radiogenic cancer risk among nuclear industry workers in 15 countries.

    2010-06-01

    In 1995 the International Agency for Research on Cancer (IARC) completed a study that involved nuclear workers from facilities in the USA, UK and Canada. The only significant, though weak, dose-related associations found were for leukaemia and multiple myeloma. The results for the Canadian cohort, which comprised workers from the facilities of Atomic Energy of Canada Limited (AECL), were compatible with those for the other national cohorts. In 2005, IARC completed a further study, involving nuclear workers from 15 countries, including Canada. In these results, the dose-related risk for leukaemia was not significant but the prominent finding was a statistically significant excess relative risk per sievert (ERR Sv(-1)) for 'all cancers excluding leukaemia'. Surprisingly, the risk ascribed to the Canadian cohort for all cancers excluding leukaemia, driven by the AECL sub-cohort, was significantly higher than the risk estimate for the 15-country cohort as a whole. We have attempted to identify why the results for the AECL cohort were so discrepant and had such a remarkable influence on the 15-country risk estimate. When considering the issues associated with data on the AECL cohorts and their handling, we noted a striking feature: a major change in outcome of studies that involved Canadian nuclear workers occurred concomitantly with the shift to when data from the National Dose Registry (NDR) of Canada were used directly rather than data from records at AECL. We concluded that an important contributor to the considerable upward shift in apparent risk in the 15-country and other Canadian studies that have been based on the NDR probably relates to pre-1971 data and, in particular, the absence from the NDR of the person-years of workers who had zero doses in the calendar years 1956 to 1970. Our recommendation was for there to be a comprehensive evaluation of the risks from radiation in nuclear industry workers in Canada, organisation by organisation, in which some of the

    The objective of the Advanced Collaborative Emissions Study (ACES) was to determine before widespread commercial deployment whether or not the new, energy-efficient, heavy duty diesel engines (2007 and 2010 EPA Emissions Standards Compliant) may generate anticipated toxic emissions that could adversely affect the environment and human health. ACES was planned to take place in three phases. In Phase 1, extensive emissions characterization of four production-intent prototype engine and control systems designed to meet 2007 standards for nitrogen oxides (NOx) and particulate matter (PM) was conducted at an existing emissions characterization facility: Southwest Research Institute (SwRI). One of the tested engines was selected (at random, after careful comparison of results) for health testing in Phase 3. In Phase 2, extensive emission characterization of three production-intent prototype engine and control systems meeting the 2010 standards (including more advanced NOx controls to meet the more stringent 2010 NOx standards) was conducted at the same test facility. In Phase 3, one engine/aftertreatment system selected from Phase 1 was further characterized during health effects studies (at an existing inhalation toxicology laboratory: Lovelace Respiratory Research Institute, [LRRI]) to form the basis of the ACES safety assessment. The Department of Energy (DOE) award provided funding for emissions characterization in Phases 1 and 2 as well as exposure characterization in Phase 3. The main health analyses in Phase 3 were funded separately and are not reported here.

    Shiers, Jamie

    2014-01-01

    The international study group on data preservation in High Energy Physics, DPHEP, achieved a major milestone in 2012 with the publication of its eagerly anticipated large-scale report [1]. This document contains a description of data preservation activities from all major high energy physics collider-based experiments and laboratories. A central message of the report is that data preservation in HEP is not possible without long term investment in not only hardware but also human resources, and with this in mind DPHEP will evolve to a new collaboration structure in 2013. This paper describes the progress made since the publication of that report – shortly before CHEP 2012 – as well as the future working directions of the new collaboration.

    During 1967-1983, the Maternal and Child Health Division of the Public Health Services funded a collaborative study of 211 newborn infants identified on newborn screening as having phenylketonuria (PKU). Subsequently, financial support was provided by the National Institute of Child Health and Human Development (NICHD). The infants were treated with a phenylalanine (Phe)-restricted diet to age 6 years and then randomized either to continue the diet or to discontinue dietary treatment altogether. One hundred and twenty-five of the 211 children were then followed until 10 years of age. In 1998, NICHD scheduled a Consensus Development Conference on Phenylketonuria and initiated a study to follow up the participants from the original Collaborative Study to evaluate their present medical, nutritional, psychological, and socioeconomic status. Fourteen of the original clinics (1967-1983) participated in the Follow-up Study effort. Each clinic director was provided with a list of PKU subjects who had completed the original study (1967-1983), and was asked to evaluate as many as possible using a uniform protocol and data collection forms. In a subset of cases, magnetic resonance imaging and spectroscopy (MRI/MRS) were performed to study brain Phe concentrations. The medical evaluations revealed that the subjects who maintained a phenylalanine-restricted diet reported fewer problems than the diet discontinuers, who had an increased rate of eczema, asthma, mental disorders, headache, hyperactivity and hypoactivity. Psychological data showed that lower intellectual and achievement test scores were associated with dietary discontinuation and with higher childhood and adult blood Phe concentrations. Abnormal MRI results were associated with higher brain Phe concentrations. Early dietary discontinuation for subjects with PKU is associated with poorer outcomes not only in intellectual ability, but also in achievement test scores and increased rates of medical and behavioural

  15. Cognitive Collaboration Found in Cardiac Physiology: Study in Classroom Environment.

    Directory of Open Access Journals (Sweden)

    Lauri Ahonen

    Full Text Available It is known that periods of intense social interaction result in shared patterns in collaborators' physiological signals. However, applied quantitative research on collaboration is hindered due to scarcity of objective metrics of teamwork effectiveness. Indeed, especially in the domain of productive, ecologically-valid activity such as programming, there is a lack of evidence for the most effective, affordable and reliable measures of collaboration quality. In this study we investigate synchrony in physiological signals between collaborating computer science students performing pair-programming exercises in a class room environment. We recorded electrocardiography over the course of a 60 minute programming session, using lightweight physiological sensors. We employ correlation of heart-rate variability features to study social psychophysiological compliance of the collaborating students. We found evident physiological compliance in collaborating dyads' heart-rate variability signals. Furthermore, dyads' self-reported workload was associated with the physiological compliance. Our results show viability of a novel approach to field measurement using lightweight devices in an uncontrolled environment, and suggest that self-reported collaboration quality can be assessed via physiological signals.

    2013-12-01

    Full Text Available The need to overcome artificial obstructions and limitations in our scientific understanding of the complexity of educational issues is the major driver of interdisciplinary collaboration in the field of Neuroeducational Studies. To get full advantage of interdisciplinary collaboration therefore, it would be necessary to identify and develop a number of practical strategies that facilitate such endeavor. The relevance literature suggests that making effective interdisciplinary collaboration in the field is dependent on a number of factors, including: creating a common language and conceptual vocabulary; developing graduate educational programs; providing training programs for neuroscientists and educators; and developing neuroeducational research organizations. It is concluded that, interdisciplinary collaboration is a potential key that ensures a more prosperous future for the field and it will be best realized based on authentic dialogue among scientists and educators.

    2008-01-01

    Computer Mediated Communication (CMC) can be used as an effective tool for student communication and collaboration. First-year, first-semester dental hygiene students self-selected groups to develop dental hygiene process of care treatment plans, written reports, and oral case presentations based on assigned clinical cases. In consultation with the University of Michigan (UM) Digital Media Commons Collaborative Technologies Teams, CMC options were identified. Two chat rooms were established within the UM's Course Management System (CTools) to provide opportunities for synchronous (simultaneous, real-time) communication. One course blog site and 8 case blog sites were developed to provide students and instructors with electronic asynchronous (nonsimultaneous) communication formats. The purpose of this study was to evaluate the effectiveness of these technologies during group case study projects. CMC has the potential to provide an effective means of collaboration and communication when the technologies align with the purpose of the project and compliment the dynamics of student groups.

    Full Text Available Building Collaborative Health Promotion Partnerships: The Jackson Heart Study. Background: Building a collaborative health promotion partnership that effectively employs principles of community-based participatory research (CBPR involves many dimensions. To ensure that changes would be long-lasting, it is imperative that partnerships be configured to include groups of diverse community representatives who can develop a vision for long-term change. This project sought to enumerate processes used by the Jackson Heart Study (JHS Community Outreach Center (CORC to create strong, viable partnerships that produce lasting change. Methods: JHS CORC joined with community representatives to initiate programs that evolved into comprehensive strategies for addressing health disparities and the high prevalence of cardiovascular disease (CVD. This collaboration was made possible by first promoting an understanding of the need for combined effort, the desire to interact with other community partners, and the vision to establish an effective governance structure. Results: The partnership between JHS CORC and the community has empowered and inspired community members to provide leadership to other health promotion projects. Conclusion: Academic institutions must reach out to local community groups and together address local health issues that affect the community. When a community understands the need for change to respond to negative health conditions, formalizing this type of collaboration is a step in the right direction.

    The Human Automation Collaboration (HAC) research project is investigating how advanced technologies that are planned for Advanced Small Modular Reactors (AdvSMR) will affect the performance and the reliability of the plant from a human factors and human performance perspective. The HAC research effort investigates the consequences of allocating functions between the operators and automated systems. More specifically, the research team is addressing how to best design the collaboration between the operators and the automated systems in a manner that has the greatest positive impact on overall plant performance and reliability. Oxstrand et al. (2013 - March) describes the efforts conducted by the researchers to identify the research needs for HAC. The research team reviewed the literature on HAC, developed a model of HAC, and identified gaps in the existing knowledge of human-automation collaboration. As described in Oxstrand et al. (2013 – June), the team then prioritized the research topics identified based on the specific needs in the context of AdvSMR. The prioritization was based on two sources of input: 1) The preliminary functions and tasks, and 2) The model of HAC. As a result, three analytical studies were planned and conduced; 1) Models of Teamwork, 2) Standardized HAC Performance Measurement Battery, and 3) Initiators and Triggering Conditions for Adaptive Automation. Additionally, one field study was also conducted at Idaho Falls Power.

    Central America is the second-most consistently active volcanic zone on Earth, after Indonesia. Centuries of volcanic activity have produced a spectacular landscape of collapsed calderas, debris flows, and thick blankets of pyroclastic materials. Volcanic activity dominates the history, culture, and daily life of Central American countries.January 2002 marked the third consecutive year in which a diverse group of volcanologists and geophysicists conducted focused field studies in Central America. This type of multi-institutional collaboration reflects the growing involvement of a number of U.S. and non-U.S. universities, and of other organizations, in Guatemala and El Salvador (Table 1).

    2013-05-01

    We review some recent endeavors and add some new results to characterize and understand underlying mechanisms in Wikipedia (WP), the paradigmatic example of collaborative value production. We analyzed the statistics of editorial activity in different languages and observed typical circadian and weekly patterns, which enabled us to estimate the geographical origins of contributions to WPs in languages spoken in several time zones. Using a recently introduced measure we showed that the editorial activities have intrinsic dependencies in the burstiness of events. A comparison of the English and Simple English WPs revealed important aspects of language complexity and showed how peer cooperation solved the task of enhancing readability. One of our focus issues was characterizing the conflicts or edit wars in WPs, which helped us to automatically filter out controversial pages. When studying the temporal evolution of the controversiality of such pages we identified typical patterns and classified conflicts accordingly. Our quantitative analysis provides the basis of modeling conflicts and their resolution in collaborative environments and contribute to the understanding of this issue, which becomes increasingly important with the development of information communication technology.

    In this paper we describe the use of visualization tools and facilities in the collaborative design of a replacement weapons system, the Reliable Replacement Warhead (RRW). We used not only standard collaboration methods but also a range of visualization software and facilities to bring together domain specialists from laboratories across the country to collaborate on the design and integrate this disparate input early in the design. This was the first time in U.S. weapons history that a weapon had been designed in this collaborative manner. Benefits included projected cost savings, design improvements and increased understanding across the project.

Although improving residents’ collaboration via interprofessional education has been investigated in many studies, little is known about the residents’ spontaneous collaborative behavior. The purpose of this exploratory study was to describe how residents spontaneously collaborate.Methods: Seven first-year residents (postgraduate year 1; three from family medicine and one each from ear, nose, and throat, obstetrics/gynecology, general surgery, and orthopedic surgery participated in two collaborative meetings with actors performing the part of other health ­professionals (ie, occupational therapist, physiotherapist, nurse, or social worker. Both meetings were built around an issue or conflict with the patients’ families reported by one professional. The residents were required to lead the meeting to collect proper information to reach a joint decision. Two team members analyzed the video recordings of the meetings using an emerging-theme qualitative methodology.Results: Although the residents spontaneously knew how to successfully communicate with other professionals, they seemed to struggle with the patient-centered approach and the shared decision-making process.Discussion: Even if the residents performed communication-wise in their collaborative role, they seemed to have perceived themselves as decision makers instead of

    Full Text Available This qualitative study focused on the collaboration between a school district and a college of education in Israel and aimed to explore how the participants created common understanding in order to promote educational change. The theoretical approach involved analyzing the institutional interconnections based on boundary practices and boundary objects and the ways these interconnections shaped the collaborative learning process, promoted educational change, and fostered educational leadership in the district and in the college. The study observed the formation of a community of practice within the boundary zone, which was developed over a three-year period by a group of 20 superintendents, the district head, and two teacher educators. Beyond concrete outcomes, such as improvement of pupils' scores on the state-mandated achievement tests, the study showed a transformation in the superintendents' perception of their roles and a cultural change in the district.

    To face the increasing prevalence of diabetes in Switzerland, a cantonal programme has been implemented. One of its goals is to promote collaborative approaches among healthcare professionals (HCPs). The objectives of the current study were to examine HCPs' perceptions about the collaboration they experience in diabetes care and to determine whether perceptions differed among professional groups. A mixed-methods study was conducted. First, a total of 332 HCPs comprising diabetes specialists and non-specialists participated by completing a questionnaire on interprofessional collaboration. Focus groups were then led in order to deepen the understanding and complement the interpretation of quantitative results. Quantitative results showed a perception of a moderate level of collaboration. Mean scores for specialists were systematically worse than those of non-specialists and more prominently in the "level of conflict dimension," which means that specialists generally perceived a lower level of collaboration and a higher level of possible conflict associated with it. Qualitative results highlighted the vagueness in role definition and emphasised a form of reluctance by general physicians to collaborate with specialists, as the physicians felt that they were losing their responsibilities. The findings suggest that it is not the need to collaborate that encourages HCPs involved in collaborative schemes to desire or to know how to successfully initiate, promote, or conduct interprofessional collaboration. This study highlights the important perceptions about collaboration that could be taken into account when planning future collaborative programmes.

  5. A scenario-based study on information flow and collaboration patterns in disaster management.

    2009-04-01

    Disaster management (DM) is a continuous, highly collaborative process involving governments, DM organisations, responders, the construction sector, and the general public. Most research approaches to DM include the development of information and communication technologies (ICT) to support the collaboration process rather than the creation of a collaboration process to provide information flows and patterns. An Intelligent Disaster Collaboration System (IDCS) is introduced in this paper as a conceptual model to integrate ICT into DM and the mitigation process and to enhance collaboration. The framework is applicable to the collaboration process at the local, regional and national levels. Within this context, the deployment of ICT tools in DM is explored and scenario-based case studies on flooding and terrorism--examples of natural and human-induced disasters, respectively--are presented. Conclusions are drawn regarding the differences found in collaboration patterns and ICT used during natural and human-induced disasters and the differences between currently available ICT and proposed ICT.

    Full Text Available Abstract Background Although general practitioners (GPs and community pharmacists (CPs are encouraged to collaborate, a true collaborative relationship does not exist between them. Our objective was to identify and analyze factors affecting GP-CP collaboration. Methods This was a descriptive-exploratory qualitative study carried out in two Spanish regions: Catalonia (Barcelona and Balearic Islands (Mallorca. Face-to-face semi-structured interviews were conducted with GPs and CPs from Barcelona and Mallorca (January 2010-February 2011. Analysis was conducted using Colaizzi’s method. Results Thirty-seven interviews were conducted. The factors affecting the relationship were different depending on timing: 1 Before collaboration had started (prior to collaboration and 2 Once the collaboration had been initiated (during collaboration. Prior to collaboration, four key factors were found to affect it: the perception of usefulness; the Primary Care Health Center (PCHC manager’s interest; the professionals’ attitude; and geography and legislation. These factors were affected by economic and organizational aspects (i.e. resources or PCHC management styles and by professionals’ opinions and beliefs (i.e. perception of the existence of a public-private conflict. During collaboration, the achievement of objectives and the changes in the PCHC management were the key factors influencing continued collaboration. The most relevant differences between regions were due to the existence of privately-managed PCHCs in Barcelona that facilitated the implementation of collaboration. In comparison with the group with experience in collaboration, some professionals without experience reported a skeptical attitude towards it, reporting that it might not be necessary. Conclusions Factors related to economic issues, management and practitioners’ attitudes and perceptions might be crucial for triggering collaboration. Interventions and strategies derived from these

    Apparent nitrogen digestibility data were obtained from 4 laboratories for 6 protein sources and 2 diet levels, 6 and 10% protein, after a 2-day adaptation period during the AACC-ASTM protein efficiency ratio (PER) and net protein ratio (NPR) collaborative studies. For 5 protein sources fed as 10% of the diet, the interlaboratory variation as measured by coefficient of variation (CV) values was low (1.5-3.5%), indicating high precision of the method. Wheat flour (6% protein diet) had the highest variation and, therefore, the lowest precision (CV of 7.10%). The interlaboratory variation (CV value) for 3 of the 4 laboratories was considerably lower, less than half that for the 4 laboratories. An analysis of variance of apparent nitrogen digestibility data indicated significant (P less than 0.05) effects for the 4-laboratory group due to laboratories and protein diets at both 10 and 6% protein levels, and for the 3-laboratory group at the 10% protein level. The 3-laboratory ANOVA for the 6% diets indicated a significant effect (P less than 0.05) due to diet only.

    Modern-day products are usually designed cooperatively by groups of experts, each with his own areas of expertise. Because of different viewpoint, evaluation standard and domain knowledge of these design groups in collaborative design system, conflict is unavoidable. In this paper, an integration conflict management system (ICMS) was presented from the aspect of all life cycle. A hierarchical constraint network was introduced to detect the conflicts. Three conflict types were classified in ICMS and different type of conflict was submitted to different resolution strategy, constraint relaxation to data conflict and knowlegdge based reasoning to knowledge conflict or schema conflict. To those conflicts hard to be resolved with the above two strategies, an arbitration was used for the conflict resolution. ICMS also provided interface with other collaborative systems such as CAE, CAD to improve the efficiency of collaborative design system.

    Background and purpose:The purpose of this exploratory case study is to describe how scholars negotiated disciplinary divides to develop and communicate to their students an understanding of the basic features of scientific knowledge. Our goals were to examine boundary crossing in interdisciplinary collaboration and to assess the efficacy of adding science content to an introductory Women's Studies course. Sample:We studied a collaboration between faculty in Biology and Women's Studies and evaluated science modules in a Women's Studies course at a regional four-year university in the Midwestern USA. The study included 186 student participants over three semesters and four faculty from Philosophy, Women's Studies and Biology. Design and method:Women's Studies and Biology faculty collaborated to design and implement science content learning modules that included the case of women and science in an introductory Women's Studies course. Qualitative data collected from faculty participants in the form of peer debrief sessions and narrative reflections were used to examine the process of interdisciplinary collaboration. Students exposed to curriculum changes were administered pre- and post-lesson surveys to evaluate their understanding of issues faced by women in science careers, the nature of science, and interest in science studies. Data from collaborators, student journal reflections, and pre-/post-lesson surveys were considered together in an evaluation of how knowledge of science was understood and taught in a Women's Studies course over a longitudinal study of three semesters. Results:We found evidence of discipline-based challenges to interdisciplinarity and disciplinary boundary crossing among collaborators. Three themes emerged from our collaboration: challenges posed by disciplinary differences, creation of a space for interdisciplinary work, and evidence of boundary crossing. Student participants exhibited more prior knowledge of Women's Studies content than

    The purpose of this study was to examine collaboration relating to public health nursing in different sized Norwegian municipalities. It sought to gain insight into factors that are important for successful collaboration, frequency of meeting points for collaborating activities and missing professionals in different sized municipalities. A cross-sectional e-post questionnaire study was carried out on a national sample of public health nurses and their collaborators. A total of 849 public health nurses (43.64%), 113 doctors at clinics and school health services (54.8%), 519 child protection workers (16.34%) and 115 midwives (41.3%) returned the questionnaire. The data were analysed using descriptive and inferential statistics. Analysis of variance (anova), Kruskal-Wallis H and chi-square tests were used to tests differences between groups. Trust, respect and collaborative competence were ranked highest by all the respondents and formalised structures, economy and leadership ranked least important in collaborative activity. The majority of the respondents stated that they do not have fewer meeting points compared with 5 years ago. Collaboration with mental health services was missed most by all respondents. There were associations between frequency of meeting points and statements on collaboration related to municipality size. Norway is in the throes of a major coordination reform. The fact that relational factors were deemed most important for successful collaboration is an important finding at a time when focus is on structural change. The findings indicate the need for further in depth qualitative studies on reasons for 'missing collaborators,' on professional cultures in different sized municipalities and on interpersonal relationships. Qualitative enquiry is necessary to gain a greater understanding of how relational concepts of respect, trust and conflict are understood by municipal public health professionals.

    Yount, Brian; McNamara, Timothy

    2008-11-06

    Effective standardization of clinical processes, which is a growing priority for healthcare provider organizations and networks, requires effective teamwork among clinicians and staff from multidisciplinary backgrounds--often from geographically dispersed facilities--to reach consensus on care practices. Yet, most healthcare provider organizations have no precedence or tools for managing large-scale, sustained, collaborative activities. This presentation explores the human and social implications of technology. It specifically addresses healthcare collaboration and describes how innovative collaboration management technologies can be used in the healthcare industry to accelerate care standardization, order set standardization and other initiatives necessary for successful computerized provider order entry and electronic health record deployments. These topics are explored through presentation of a survey of healthcare executives and a case study of an advanced collaboration application that was adapted and deployed in a partnership between a large healthcare provider organization and a commercial developer of document management and collaboration management technologies.

    Interdisciplinary collaboration is essential for the advance of research. As domain subjects become more and more specialized, researchers need to cross disciplines for insights from peers in other areas to have a broader and deeper understand of a topic at micro- and macro-levels. We developed a 3D virtual learning environment that served as a platform for faculty to plan curriculum, share educational beliefs, and conduct cross-discipline research for effective learning. Based upon the scripts designed by faculty from five disciplines, virtual doctors, nurses, or patients interact in a 3D virtual hospital. The teaching vignettes were then converted to video clips, allowing users to view, pause, replay, or comment on the videos individually or in groups. Unlike many existing platforms, we anticipated a value-added by adding a social networking capacity to this virtual environment. The focus of this paper is on the cost-efficiency and system design of the virtual learning environment.

    Full Text Available Abstract Background The EuroCMR registry sought to evaluate indications, image quality, safety and impact on patient management of clinical routine CMR in a multi-national European setting. Furthermore, interim analysis of the specific protocols should underscore the prognostic potential of CMR. Methods Multi-center registry with consecutive enrolment of patients in 57 centers in 15 countries. More than 27000 consecutive patients were enrolled. Results The most important indications were risk stratification in suspected CAD/Ischemia (34.2%, workup of myocarditis/cardiomyopathies (32.2%, as well as assessment of viability (14.6%. Image quality was diagnostic in more than 98% of cases. Severe complications occurred in 0.026%, always associated with stress testing. No patient died during or due to CMR. In 61.8% CMR findings impacted on patient management. Importantly, in nearly 8.7% the final diagnosis based on CMR was different to the diagnosis before CMR, leading to a complete change in management. Interim analysis of suspected CAD and risk stratification in HCM specific protocols revealed a low rate of adverse events for suspected CAD patients with normal stress CMR (1.0% per year, and for HCM patients without LGE (2.7% per year. Conclusion The most important indications in Europe are risk stratification in suspected CAD/Ischemia, work-up of myocarditis and cardiomyopathies, as well as assessment of viability. CMR imaging is a safe procedure, has diagnostic image quality in more than 98% of cases, and its results have strong impact on patient management. Interim analyses of the specific protocols underscore the prognostic value of clinical routine CMR in CAD and HCM. Condensed abstract The EuroCMR registry sought to evaluate indications, image quality, safety and impact on patient management of clinical routine CMR in a multi-national European setting in a large number of cases (n > 27000.

    2015-01-01

    Full Text Available The purpose of this study was to test the usefulness of a slightly modified Shannon's diversity index (H as a numerical measure of intragroup research collaboration diversity based on coauthorship. Altogether, 527 peer-reviewed scientific papers by two university departments were used as the study material. Nonrandom rationalized sampling was executed to enable the confirmation of the authors' affiliations. The smallest unit of collaboration, i.e., a pair of authors, was created by matching every author with each of the coauthors from the same department he or she collaborated with. H was calculated at the department level and compared with the previously published, coauthorship based measures of research collaboration: The collaborative index (CI, degree of collaboration (DC and collaboration diversity index (CDI. Obviously, H expressed a different aspect of research collaboration than the existing indexes. Compared to CI, DC, and CDI, H revealed novel aspects of collaboration when the abundance of collaboration increased and the distribution of collaborative relations between coauthors moved closer to the uniform distribution at the same time. H can provide additional information about collaborative relationships between researchers based on coauthorship, and it should be considered as a partial indicator of research collaboration.

    Blooms of the toxic marine dinoflagellate Karenia brevis cause massive fish kills and other public health and economic problems in coastal waters throughout the Gulf of Mexico [Steidinger, 2009]. These harmful algal blooms (HABs) are a gulf-wide problem that require a synoptic observing system for better serving decision-making needs. The major nutrient sources that initiate and maintain these HABs and the possible connectivity of blooms in different locations are important questions being addressed through new collaborations between Mexican and U.S. researchers and government institutions. These efforts were originally organized under the U.S./Mexico binational partnership for the HABs Observing System (HABSOS), led by the U.S. Environmental Protection Agency's Gulf of Mexico Program (EPAGMP) and several agencies in Veracruz, Mexico, since 2006. In 2010 these efforts were expanded to include other Mexican states and institutions with the integrated assessment and management of the Gulf of Mexico Large Marine Ecosystem (GoMLME) program sponsored by the Global Environment Facility (GEF), the United Nations Industrial Development Organization (UNIDO), the Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT), and the National Oceanic and Atmospheric Administration (NOAA).

    Full Text Available Abstract Background Collaborations are important to health promotion in addressing multi-party problems. Interest in collaborative processes in health promotion is rising, but still lacks monitoring instruments. The authors developed the DIagnosis of Sustainable Collaboration (DISC model to enable comprehensive monitoring of public health collaboratives. The model focuses on opportunities and impediments for collaborative change, based on evidence from interorganizational collaboration, organizational behavior and planned organizational change. To illustrate and assess the DISC-model, the 2003/2004 application of the model to the Dutch whole-school health promotion collaboration is described. Methods The study combined quantitative research, using a cross-sectional survey, with qualitative research using the personal interview methodology and document analysis. A DISC-based survey was sent to 55 stakeholders in whole-school health promotion in one Dutch region. The survey consisted of 22 scales with 3 to 8 items. Only scales with a reliability score of 0.60 were accepted. The analysis provided for comparisons between stakeholders from education, public service and public health. The survey was followed by approaching 14 stakeholders for a semi-structured DISC-based interview. As the interviews were timed after the survey, the interviews were used to clarify unexpected and unclear outcomes of the survey as well. Additionally, a DISC-based document analysis was conducted including minutes of meetings, project descriptions and correspondence with schools and municipalities. Results Response of the survey was 77% and of the interviews 86%. Significant differences between respondents of different domains were found for the following scales: organizational characteristics scale, the change strategies, network development, project management, willingness to commit and innovative actions and adaptations. The interviews provided a more specific picture

    Genome-wide association study (GWAS) consortia and collaborations formed to detect genetic loci for common phenotypes or investigate gene-environment (G*E) interactions are increasingly common. While these consortia effectively increase sample size, phenotype heterogeneity across studies represents a major obstacle that limits successful identification of these associations. Investigators are faced with the challenge of how to harmonize previously collected phenotype data obtained using different data collection instruments which cover topics in varying degrees of detail and over diverse time frames. This process has not been described in detail. We describe here some of the strategies and pitfalls associated with combining phenotype data from varying studies. Using the Gene Environment Association Studies (GENEVA) multi-site GWAS consortium as an example, this paper provides an illustration to guide GWAS consortia through the process of phenotype harmonization and describes key issues that arise when sharing data across disparate studies. GENEVA is unusual in the diversity of disease endpoints and so the issues it faces as its participating studies share data will be informative for many collaborations. Phenotype harmonization requires identifying common phenotypes, determining the feasibility of cross-study analysis for each, preparing common definitions, and applying appropriate algorithms. Other issues to be considered include genotyping timeframes, coordination of parallel efforts by other collaborative groups, analytic approaches, and imputation of genotype data. GENEVA's harmonization efforts and policy of promoting data sharing and collaboration, not only within GENEVA but also with outside collaborations, can provide important guidance to ongoing and new consortia.

    The benefits of researcher-practitioner (R-P) collaborations focused on violence against women (VAW) are many. Such projects support researchers and practitioners working together to create uniquely comprehensive projects that have the potential to change practices, policies, and services. Extant literature is limited in that it has (a) focused on the experiences of a very limited number of collaborations, (b) ignored collaborations conducted in the context of the criminal justice system, and (c) excluded as a focus the products that result from the collaborations and their dissemination. Therefore, the goal of this qualitative study is to identify the essential elements to consider for successful R-P collaborations on VAW research in the criminal justice system.

    2006-12-01

    Full Text Available Abstract Background Collaboration between general practitioners (GPs and specialists has been the focus of many collaborative care projects during the past decade. Unfortunately, quite a number of these projects failed. This raises the question of what motivates medical specialists to initiate and continue participating with GPs in new collaborative care models. The following question is addressed in this study: What motivates medical specialists to initiate and sustain new models for collaborating with GPs? Methods We conducted semi-structured interviews with eighteen medical specialists in the province of Groningen, in the North of The Netherlands. The sampling criteria were age, gender, type of hospital in which they were practicing, and specialty. The interviews were recorded, fully transcribed, and analysed by three researchers working independently. The resulting motivational factors were grouped into categories. Results 'Teaching GPs' and 'regulating patient flow' (referrals appeared to dominate when the motivational factors were considered. In addition, specialists want to develop relationships with the GPs on a more personal level. Most specialists believe that there is not much they can learn from GPs. 'Lack of time', 'no financial compensation', and 'no support from colleagues' were considered to be the main concerns to establishing collaborative care practices. Additionally, projects were often experienced as too complex and time consuming whereas guidelines were experienced as too restrictive. Conclusion Specialists are particularly interested in collaborating because the GP is the gatekeeper for access to secondary health care resources. Specialists feel that they are able to teach the GPs something, but they do not feel that they have anything to learn from the GPs. With respect to professional expertise, therefore, specialists do not consider GPs as equals. Once personal relationships with the GPs have been established, an

    We (and cooperators) suggest studying the evolution of the extended collaboration networks by a dyad-act organizing model. The analytic and numeric studies of the model lead to a conclusion that most of the collaboration networks should show a dyad act-degree distribution (how many acts a dyad belongs to) between a power law and an exponential function, which can be described by a shifted power law. We have done an empirical study on dyad act-degree distribution in some collaboration networks. They are: the train networks in China, the bus network of Beijing, and traditional Chinese medical prescription formulation network. The results show good agreement with this conclusion. We also discuss what dyad act-degree implies in these networks and what are the possible applications of the study. The details will be published elsewhere.

  16. Towards a measurement of internalization of collaboration scripts in the medical context – results of a pilot study

    Directory of Open Access Journals (Sweden)

    Kiesewetter, Jan

    2015-08-01

    Full Text Available Background: Collaboration as a key qualification in medical education and everyday routine in clinical care can substantially contribute to improving patient safety. Internal collaboration scripts are conceptualized as organized - yet adaptive – knowledge that can be used in specific situations in professional everyday life. This study examines the level of internalization of collaboration scripts in medicine. Internalization is understood as fast retrieval of script information.Goal: The goals of the current study were the assessment of collaborative information, which is part of collaboration scripts, and the development of a methodology for measuring the level of internalization of collaboration scripts in medicine. Method: For the contrastive comparison of internal collaboration scripts, 20 collaborative novices (medical students in their final year and 20 collaborative experts (physicians with specialist degrees in internal medicine or anesthesiology were included in the study. Eight typical medical collaborative situations as shown on a photo or video were presented to the participants for five seconds each. Afterwards, the participants were asked to describe what they saw on the photo or video. Based on the answers, the amount of information belonging to a collaboration script (script-information was determined and the time each participant needed for answering was measured. In order to measure the level of internalization, script-information per recall time was calculated.Results: As expected, collaborative experts stated significantly more script-information than collaborative novices. As well, collaborative experts showed a significantly higher level of internalization.Conclusions: Based on the findings of this research, we conclude that our instrument can discriminate between collaboration novices and experts. It therefore can be used to analyze measures to foster subject-specific competency in medical education.

    2006-11-01

    Full Text Available Abstract Background Governments may be overwhelmed by a large-scale public health emergency, such as a massive bioterrorist attack or natural disaster, requiring collaboration with businesses and other community partners to respond effectively. In Georgia, public health officials and members of the Business Executives for National Security have successfully collaborated to develop and test procedures for dispensing medications from the Strategic National Stockpile. Lessons learned from this collaboration should be useful to other public health and business leaders interested in developing similar partnerships. Methods The authors conducted a case study based on interviews with 26 government, business, and academic participants in this collaboration. Results The partnership is based on shared objectives to protect public health and assure community cohesion in the wake of a large-scale disaster, on the recognition that acting alone neither public health agencies nor businesses are likely to manage such a response successfully, and on the realization that business and community continuity are intertwined. The partnership has required participants to acknowledge and address multiple challenges, including differences in business and government cultures and operational constraints, such as concerns about the confidentiality of shared information, liability, and the limits of volunteerism. The partnership has been facilitated by a business model based on defining shared objectives, identifying mutual needs and vulnerabilities, developing carefully-defined projects, and evaluating proposed project methods through exercise testing. Through collaborative engagement in progressively more complex projects, increasing trust and understanding have enabled the partners to make significant progress in addressing these challenges. Conclusion As a result of this partnership, essential relationships have been established, substantial private resources and

    2011-05-01

    Full Text Available Abstract Background Collaboration between general practice and mental health care has been recognised as necessary to provide good quality healthcare services to people with mental health problems. Several studies indicate that collaboration often is poor, with the result that patient' needs for coordinated services are not sufficiently met, and that resources are inefficiently used. An increasing number of mental health care workers should improve mental health services, but may complicate collaboration and coordination between mental health workers and other professionals in the treatment chain. The aim of this qualitative study is to investigate strengths and weaknesses in today's collaboration, and to suggest improvements in the interaction between General Practitioners (GPs and specialised mental health service. Methods This paper presents a qualitative focus group study with data drawn from six groups and eight group sessions with 28 health professionals (10 GPs, 12 nurses, and 6 physicians doing post-doctoral training in psychiatry, all working in the same region and assumed to make professional contact with each other. Results GPs and mental health professionals shared each others expressions of strengths, weaknesses and suggestions for improvement in today's collaboration. Strengths in today's collaboration were related to common consultations between GPs and mental health professionals, and when GPs were able to receive advice about diagnostic treatment dilemmas. Weaknesses were related to the GPs' possibility to meet mental health professionals, and lack of mutual knowledge in mental health services. The results describe experiences and importance of interpersonal knowledge, mutual accessibility and familiarity with existing systems and resources. There is an agreement between GPs and mental health professionals that services will improve with shared knowledge about patients through systematic collaborative services, direct cell

    Studies on social networks highlight the importance of network structure or structural properties of a given network and its impact on performance outcome. One of the important properties of this network structure is referred as "social capital" which is the "network of contacts" and the associated values attached to these networks of contacts. In this study, our aim is to provide empirical evidence of the influence of social capital and performance within the context of academic collaboratio...

  9. Collaborative Learning in Problem Solving: A Case Study in Metacognitive Learning

    Directory of Open Access Journals (Sweden)

    Shelly L. Wismath

    2015-12-01

    Full Text Available Problem solving and collaborative communication are among the key 21st century skills educators want students to develop. This paper presents results from a study of the collaborative work patterns of 133 participants from a university level course designed to develop transferable problem-solving skills. Most of the class time in this course was spent on actually solving puzzles, with minimal direct instruction; students were allowed to work either independently or in small groups of two or more, as they preferred, and to move back and forth between these two modalities as they wished. A distinctive student-driven pattern blending collaborative and independent endeavour was observed, consistently over four course offerings in four years. We discuss a number of factors which appear to be related to this variable pattern of independent and collaborative enterprise, including the thinking and learning styles of the individuals, the preference of the individuals, the types of problems being worked on, and the stage in a given problem at which students were working. We also consider implications of these factors for the teaching of problem solving, arguing that the development of collaborative problem solving abilities is an important metacognitive skill.

    The quantity of wildlife extracted from the Amazon has increased in the past decades as a consequence of an increase in human population density and income growth. To evaluate the spatial distribution of studies on subsistence and/or commercial hunting conducted in the Brazilian Amazon, we selected eight mid-sized and large-bodied aquatic vertebrate species with a history of human exploitation in the region. We used a combination of searches in the gray and scientific literature from the past 24 years to provide an updated distributional map of studies on the target species. We calculated the distances between the study sites and the locations of the research institutes/universities that the first and last authors of the same study were affiliated to. For the period of 1990 to 2014, we found 105 studies on the subsistence and/or commercial hunting of aquatic vertebrates in the Brazilian Amazon in 271 locations that involved 43 institutions (37 Brazilian and 6 international). The spatial distribution of the studies across the Brazilian Amazon varied, but over 80% took place in the northeast and central Amazon, encompassing three States of the Legal Brazilian Amazon (Amazonas, 51.42%; Pará, 19.05%; and Amapá, 16.19%). Over half of the research study sites (52.91%) were within 500 km of the research institute/university of the first or last authors. Some research institutes/universities did not have any inter-institutional collaborations, while others collaborated with eight or more institutes. Some research institutes/universities conducted many studies, had an extensive collaboration network, and contributed greatly to the network of studies on Amazonian aquatic vertebrates. Our research contributes to the knowledge of studies on the subsistence and/or commercial hunting of the most exploited aquatic vertebrates of the Brazilian Amazon, illustrates the impact that collaboration networks have on research, and highlights potential areas for improvement and the

    Full Text Available Abstract Background Comprising of both organisational and patient level components, collaborative care is a potentially powerful intervention for improving depression treatment in UK primary Care. However, as previous models have been developed and evaluated in the United States, it is necessary to establish the effect of collaborative care in the UK in order to determine whether this innovative treatment model can replicate benefits for patients outside the US. This Phase III trial was preceded by a Phase II patient level RCT, following the MRC Complex Intervention Framework. Methods/Design A multi-centre controlled trial with cluster-randomised allocation of GP practices. GP practices will be randomised to usual care control or to "collaborative care" - a combination of case manager coordinated support and brief psychological treatment, enhanced specialist and GP communication. The primary outcome will be symptoms of depression as assessed by the PHQ-9. Discussion If collaborative care is demonstrated to be effective we will have evidence to enable the NHS to substantially improve the organisation of depressed patients in primary care, and to assist primary care providers to deliver a model of enhanced depression care which is both effective and acceptable to patients.

  17. The NWMO Study and Process of Collaborative Development

    Energy Technology Data Exchange (ETDEWEB)

    Facella, Jo-Ann [Nuclear Waste Management Organization, Toronto (Canada)

    2006-09-15

    The Nuclear Waste Management Organization (NWMO) was tasked, through federal legislation, to conduct a study of long term approaches for the management of spent nuclear fuel and recommend a preferred approach to the Government of Canada. The Nuclear Fuel Waste Act requires the NWMO to study at least three approaches, one for each of deep geological disposal in the Canadian Shield, storage at nuclear reactor sites, and centralized storage either above or below ground. It also requires that within three years the NWMO make a recommendation to government on a preferred approach for Canada. One of these approaches - that of deep geological disposal in the Canadian Shield - was the subject of an extensive environmental assessment through much of the 1990s. This assessment concluded that, on balance the concept of deep geological disposal had been adequately demonstrated from a technical perspective, but the same was not true from a social perspective. The environmental assessment panel indicated there was no evidence of broad public support for the concept and that it lacked the required level of public acceptability to be adopted. The lesson taken from this assessment was that to choose the right technical solution, we must first ask what requirements the technology has to live up to. We need to know what social values citizens want to protect. The study process was designed to ask Canadians for the list of values and objectives against which a management approach should be assessed, and then engage Canadians in a dialogue to assess the approaches against that list. Citizens were asked to provide direction on: The questions which ought to be asked and answered in the study, and the key issues to be addressed in the assessment of the management approaches; The range of technical methods which ought to be considered in the NWMO study; The risks, costs and benefits of each management approach; and Design of the overarching management structure and implementation plans

    (note: acronym glossary at end of abstract) For scientists to have confidence in the veracity of data sets and computational processes not under their control, operational transparency must be much greater than previously required. Being able to have a universally understood and machine-readable language for describing such things as the completeness of metadata, data provenance and uncertainty, and the discrete computational steps in a complex process take on increased importance. OGC has been involved with technological issues associated with climate change since 2005 when we, along with the IEEE Committee on Earth Observation, began a close working relationship with GEO and GEOSS (http://earthobservations.org). GEO/GEOS provide the technology platform to GCOS who in turn represents the earth observation community to UNFCCC. OGC and IEEE are the organizers of the GEO/GEOSS Architecture Implementation Pilot (see http://www.ogcnetwork.net/AIpilot). This continuing work involves closely working with GOOS (Global Ocean Observing System) and WMO (World Meteorological Organization). This session reports on the findings of recent work within the OGC’s community of software developers and users to apply geospatial web services to the climate studies domain. The value of this work is to evolve OGC web services, moving from data access and query to geo-processing and workflows. Two projects will be described, the GEOSS API-2 and the CCIP. AIP is a task of the GEOSS Architecture and Data Committee. During its duration, two GEO Tasks defined the project: AIP-2 began as GEO Task AR-07-02, to lead the incorporation of contributed components consistent with the GEOSS Architecture using a GEO Web Portal and a Clearinghouse search facility to access services through GEOSS Interoperability Arrangements in support of the GEOSS Societal Benefit Areas. AIP-2 concluded as GEOS Task AR-09-01b, to develop and pilot new process and infrastructure components for the GEOSS Common

  10. Networking: a study in planning and developing cross-cultural collaboration

    Sanjeev Singh

    2002-12-01

    Full Text Available This paper reports on a collaboration between the authors at the University of Brighton (UK and the University of Delhi, South Campus. The collaboration came about as a result of the EU-India Cross-Cultural Innovation Network collaboration programme, a project involving several universities and organizations across Europe and India. The authors of this paper both lecture in the area of computer networking. Following meetings in Delhi, they agreed to work together to produce a Web-based networking resource to be generated by the students of both institutions. The first phase of development involved the mounting of Web-based tutorials and documents produced by the students. The second phase will centre on the development of a knowledge base generated by the interaction of the students within an asynchronous forum. Running alongside these phases will be a collaborative bookmarking system, a database in which the students will post URLs of Web-based resources that they find useful in their studies. This system incorporates a form of collaborative filtering, an evolutionary mechanism which seeks to embody the qualities that students value in resources to provide a dynamic set of ratings to assist in the selection of those of most use. The planning of such a system raises some unusual issues, not least in the process of collaboration itself, with concerns as diverse as technical compatibility, institutional and cultural differences, timezones and the reliability of email. Limited bandwidth between our institutions causes special problems with the interactive elements of the resource. We present the methods we are investigating to reduce the impact of this. The fact that the students share an intellectual discipline but are otherwise separated by a cultural and geographical divide is expected to lead to fruitful diversity in thinking and approaches to problem-solving.

    Variability in gross tumour volume (GTV) definition is a major source of systematic error in conformal radiotherapy. This prospective study assesses the role of multidisciplinary collaboration between oncologists and radiologists in defining lung cancer volumes. Twenty patients with non-small cell lung cancer due to receive three-dimensional conformal radiotherapy formed the study population. GTVs were defined by a radiologist (GTVrad) and an oncologist (GTVonc) using available clinical information and imaging. A collaborative meeting was then held to agree on a final, common GTV (GTVfin) to be used for treatment planning, and differences analysed. The collaboration changed the GTV in 19/20 patients with a total of 50 regions being edited. Changes made were categorized as (a) differentiation of tumour from atelectasis or ground glass shadowing, (b) separation of tumour from vasculature, and (c) defining mediastinal extent of tumour. Oncologists were more confident in the GTVfin than the GTVonc. The radiologist took longer to define the GTV than the oncologist. Real-time collaborative GTV definition by a radiologist and oncologist is practical and feasible. This approach allows specific areas of uncertainty to be categorized and focussed on, reducing systematic error in GTV definition. The physician's approach to risk and decision making for each patient may also play a role.

    Full Text Available The increase competitions as well as technological advancements have created motivation among business owners to look for more innovative ideas from outside their organizations. Many enterprises collaborate with other organizations to empower themselves through innovative ideas. These kinds of collaborations can be observed as a concept called Regional Innovation System. These collaborations include inter-firm collaborations, research organizations, intermediary institutions and governmental agencies. The primary objective of this paper is to evaluate relationships between Collaborative Networks and Innovation in information technology business units located in province of Tehran, Iran. The research method utilized for the present study is descriptive-correlation. To evaluate the relationships between independent and dependent variables, canonical correlation analysis (CCA is used. The results confirm the previous findings regarding the relationship between Collaborative Networks and Innovation. Among various dimensions of Collaboration, Collaboration with governmental agencies had a very small impact on the relationship between collaboration networks and innovation. In addition, the results show that in addition to affecting product innovation and process innovation, collaboration networks also affected management innovation.

  16. Collaborative ethnography for information systems research Studying knowledge work practices and designing supportive information systems

    Directory of Open Access Journals (Sweden)

    Ronald Maier

    2012-04-01

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

    An international collaborative study was organised to establish the World Health Organization (WHO) 3(rd) International Standard (IS) for neomycin. Ten laboratories from different countries participated in the collaborative study. The potency of the candidate material, a freeze-dried preparation, was estimated by microbiological assays with sensitive micro-organisms. To ensure continuity between consecutive batches, the 2(nd) IS for neomycin was used as a standard. Based on the results of the study, the 3(rd) IS for neomycin was adopted at the meeting of the WHO Expert Committee on Biological Standardization (ECBS) in 2012 with an assigned potency of 19,050 IU per vial. The 3(rd) IS for neomycin is available from the European Directorate for the Quality of Medicines & HealthCare (EDQM).

    Full Text Available In this hermeneutic phenomenological study, we examined the experience of interprofessional collaboration from the perspective of nursing and medical students. Seventeen medical and nursing students from two different universities participated in the study. We used guiding questions in face-to-face, conversational interviews to explore students’ experience and expectations of interprofessional collaboration within learning situations. Three themes emerged from the data: the great divide, learning means content, and breaking the ice. The findings suggest that the experience of interprofessional collaboration within learning events is influenced by the natural clustering of shared interests among students. Furthermore, the carry-forward of impressions about physician–nurse relationships prior to the educational programs and during clinical placements dominate the formation of new relationships and acquisition of new knowledge about roles, which might have implications for future practice.

    Full Text Available Introduction: People in various professions may face discrimination. In the nursing field, discrimination among nurses in the workplace, regardless of race, gender or religion have not been studied; a problem that leads to a reduction in the quality of nursing care and nurse turnover. Discovery of the concerns of nurses about inter-professional collaboration is the purpose of this study. Methods: The present study is conducted by using a qualitative content analysis. The data collection process included 22 unstructured and in-depth interviews with nurses between April 2012 and February 2013 in the medical teaching centers of Iran. A purposive sampling method was used. All interviews were recorded, typed, and analyzed simultaneously. Results: The category obtained from explaining nurses' experiences of inter-professional collaboration was "discrimination" that included two subcategories, namely (1 lack of perspective towards equality in authorities, and (2 professional respect and value deficit.Conclusion: Nurses' experiences are indicating their perception of discrimination that influences the collaboration between nurses, which should be taken into account by managers. The findings of the present study help to managers about decision making on how to deal with staff and can be helpful in preventing nurse turnover and providing better services by nurses.

    Owen-Stone, Deborah S.

    The purpose of this concurrent mixed methods study was to examine the collaborative relationship between scientists and science teachers and to incorporate and advocate scientific literacy based on past and current educational theories such as inquiry based teaching. The scope of this study included archived student standardized test scores, semi-structured interviews, and a Likert scale survey to include open-ended comments. The methodology was based on the guiding research question: To what extent and in what ways does the collaboration and inquiry methodology, with GTF and PT teams, serve toward contributing to a more comprehensive and nuanced understanding of this predicting relationship between student PASS scores, inquiry skills, and increased scientific literacy for GTF's, PT's, and students via an integrative mixed methods analysis? The data analysis considerations were derived from the qualitative data collected from the three GTF/PT teams by the use of recorded interviews and text answered survey comments. The quantitative data of archived student Palmetto Assessment of State Standards (PASS) scores on scientific literacy and inquiry tests and the Likert-scale portion of the survey were support data to the aforementioned qualitative data findings. Limitations of the study were (1) the population of only the GK-12 teachers and their students versus the inclusion of participants that did not experience the GK-12 Fellow partnerships within their classrooms, should they be considered as participants, (2) involved the researcher as a participant for two years of the program and objectivity remained through interpretation and well documented personal reflections and experiences to inform accuracy, and (3) cultural diversity contributed to the relationship formed between the research Fellow and science educator and communication and scientific language did form a barrier between the Fellow, educator, and student rapport within the classroom.

    2009-01-01

    The collaboration relationships between header files in the source code of Linux kernels are analyzed by constructing a weighted Header File Collaboration Network (HFCN): each node represents a header file; two nodes are connected if corresponding header files are both included in the same source file at least once; also the link weight is assigned to evaluate the intensity of co-inclusion of two header files. Through using appropriate non-weighted and weighted quantities, structural properties of two kinds of HFCN networks(HFCN-Ⅰ and HFCN-Ⅱ) are characterized and analyzed. The study of Linux kernels from the view-point of complex networks can provide a better description of the organizational principles and evolving mechanism of complex software systems.

    Full Text Available This paper presents a case study of online learning. It is based on the researcher’s participation in an inter-university collaborative module at two higher education institutions in South Africa and the United States from August to December 2001. The paper addresses the advantages and disadvantages of the online learning environment and learning in a Virtual Classroom. It provides a critical interpretation of the virtual classroom experienced in this collaboration between institutions. It finds that there are benefits from applying this technology in educational practices and programs particularly in the African context where a large majority of school-leaving learners have little or no access to higher education. However, it also expounds the NEPAD (New Partnership for Africa’s Development initiative to produce ICT in schools throughout Africa to fulfil the Millennium Development Goals on education in developing countries.

    Full Text Available Mass collaborative product development (MCPD benefits people by high innovation products with lower cost and shorter lead time due to quick development of group innovation, Internet-based customization, and prototype manufacturing. Simulation is an effective way to study the evolution process and therefore to guarantee the success of MCPD. In this paper, an agent behavior-based simulation approach of MCPD is developed, which models the MCPD process as the interactive process of design agents and the environment objects based on Complex Adaptive System (CAS theory. Next, the structure model of design agent is proposed, and the modification and collaboration behaviors are described. Third, the agent behavior-based simulation flow of MCPD is designed. At last, simulation experiments are carried out based on an engineering case of mobile phone design. The experiment results show the following: (1 the community scale has significant influence on MCPD process; (2 the simulation process can explicitly represent the modification and collaboration behaviors of design agents; (3 the community evolution process can be observed and analyzed dynamically based on simulation data.

    2003-01-01

    The practice of detecting and enumerating all oxidase-negative, glucose-fermenting-Gram-negative rods (i.e., the family Enterobacteriaceae) is used to indicate unsanitary or inadequate food processing conditions. The objective of this interlaboratory collaborative study was to evaluate and compare the methods described in Standard Methods for the Examination of Dairy Products (SMEDP) and the Compendium of Methods for the Microbiological Examination of Foods (Compendium) with a commercial product, the 3M Petrifilm Enterobacteriaceae Count Plate, for the recovery of Enterobacteriaceae in foods. Six foods--cheddar cheese, milk, flour, frozen prepared meals, frozen broccoli, and nut pieces--were analyzed for Enterobacteriaceae by 12 collaborating laboratories. For each food tested, the collaborators received 8 blind test portions consisting of a control test portion and 3 levels of inoculated test portion, each in duplicate. Each test portion was tested by the Petrifilm Enterobacteriaceae Count Plate method as well as the SMEDP or Compendium methods. The precision estimates (repeatability or within-laboratory variation, and reproducibility or between-laboratory variation) were calculated with standard statistical techniques.

  18. A study of the development of collaborative explanations in molecular genetics by secondary science students

    Gribbin, Mary Elizabeth

    Current science education standards documents include recommendations that learning activities employ authentic scientific inquiry. The product of scientific inquiry is a scientific explanation, and student inquiry should therefore be directed toward development of explanations. Science is a collaborative enterprise, and inquiry learning should include activities requiring collaboration. The ability of secondary students in an academic enrichment program in molecular genetics to collaborate to develop explanations in response to assigned questions for discussion was investigated in this study. The following research questions were addressed: (1) What kinds of explanations do students produce? (2) What kinds of cognitive and social processes do students engage in? (3) Which cognitive and social processes promote the development of better explanations? The participants of this study were thirty-four students from nineteen New Jersey high schools who took part in a four-week summer enrichment program in genetics and molecular biology at the Waksman Institute, Rutgers, The State University of New Jersey. The students were of high or very high academic ability. Students met once each week in small groups to discuss a challenging science question presented by the instructor. These discussions were audio taped, and data used in the study were obtained primarily from transcripts of the tapes. The procedure used to evaluate the students' arguments was based upon methods for analyzing the structure of arguments described by Chinn & Anderson (1999) and Halpern (1996), and employed taxonomies developed by the investigator. The taxonomies were shown to be an effective tool for evaluating and characterizing student discussions in terms of logical reasoning, content knowledge, and collaboration. Analyses of the transcripts indicated that groups in which the students had prior knowledge of the content related to the discussion questions produced complete and valid arguments, but

    Full Text Available Abstract Background Recommender systems have shown tremendous value for the prediction of personalized item recommendations for individuals in a variety of settings (e.g., marketing, e-commerce, etc.. User-based collaborative filtering is a popular recommender system, which leverages an individuals’ prior satisfaction with items, as well as the satisfaction of individuals that are “similar”. Recently, there have been applications of collaborative filtering based recommender systems for clinical risk prediction. In these applications, individuals represent patients, and items represent clinical data, which includes an outcome. Methods Application of recommender systems to a problem of this type requires the recasting a supervised learning problem as unsupervised. The rationale is that patients with similar clinical features carry a similar disease risk. As the “Big Data” era progresses, it is likely that approaches of this type will be reached for as biomedical data continues to grow in both size and complexity (e.g., electronic health records. In the present study, we set out to understand and assess the performance of recommender systems in a controlled yet realistic setting. User-based collaborative filtering recommender systems are compared to logistic regression and random forests with different types of imputation and varying amounts of missingness on four different publicly available medical data sets: National Health and Nutrition Examination Survey (NHANES, 2011-2012 on Obesity, Study to Understand Prognoses Preferences Outcomes and Risks of Treatment (SUPPORT, chronic kidney disease, and dermatology data. We also examined performance using simulated data with observations that are Missing At Random (MAR or Missing Completely At Random (MCAR under various degrees of missingness and levels of class imbalance in the response variable. Results Our results demonstrate that user-based collaborative filtering is consistently inferior

    To study impacts of various random effects and parameters of collaborative studies on the precision of quantitation methods of genetically modified (GM) crops, we developed a set of random effects models for cycle time values of a standard curve-based relative real-time PCR that makes use of an endogenous gene sequence as the internal standard. The models and data from a published collaborative study for six GM lines at four concentration levels were used to simulate collaborative studies under various conditions. Results suggested that by reducing the numbers of well replications from three to two, and standard levels of endogenous sequence from five to three, the number of unknown samples analyzable on a 96-well PCR plate in routine analyses could be almost doubled, and still the acceptable repeatability RSD (RSDr crops by real-time PCR and their collaborative studies.

    Formerly named the Nevada Test Site, the Nevada National Security Site (NNSS) was the historical site for nuclear weapons testing from the 1950s to the early 1990s. The site was renamed in 2010 to reflect the diversity of nuclear, energy, and homeland security activities now conducted at the site. Biological and ecological programs and research have been conducted on the site for decades to address the impacts of radiation and to take advantage of the relatively undisturbed and isolated lands for gathering basic information on the occurrence and distribution of native plants and animals. Currently, the Office of the Assistant Manager for Environmental Management of the U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Site Office (NNSA/NSO) oversees the radiological biota monitoring and ecological compliance programs on the NNSS. The top priority of these programs are compliance with federal and state regulations. They focus on performing radiological dose assessments for the public who reside near the NNSS and for populations of plants and animals on the NNSS and in protecting important species and habitat from direct impacts of mission activities. The NNSS serves as an invaluable outdoor laboratory. The geographic and ecological diversity of the site offers researchers many opportunities to study human influences on ecosystems. NNSA/NSO has pursued collaborations with outside agencies and organizations to be able to conduct programs and studies that enhance radiological biota monitoring and ecosystem preservation when budgets are restrictive, as well as to provide valuable scientific information to the human health and natural resource communities at large. NNSA/NSO is using one current collaborative study to better assess the potential dose to the off-site public from the ingestion of game animals, the most realistic pathway for off-site public exposure at this time from radionuclide contamination on the NNSS.

    We present the results of a collaborative study for the establishment of a replacement International Standard (IS) for Tetanus Toxoid Adsorbed. Two candidate preparations were included in the study, one of which was established as the 4th IS for Tetanus Toxoid Adsorbed at the WHO Expert Committee on Biological Standardization meeting in October 2010. This preparation was found to have a unitage of 490 IU/ampoule, based on calibration in guinea pig challenge assays. Results from mouse challenge assays suggest that the relative performance of two candidate preparations may differ significantly between guinea pigs and mice. The authors note that the number of laboratories that performed guinea pig challenge assays, which are used to calibrate and assign IU, is much lower than in previous collaborative studies and this may have implications for calibration of replacement standards in the future. The issue of assigning separate units to the IS for guinea pig and mouse assays is discussed. The study also assessed performance of the replacement standard in serological assays which are used as alternative procedures to challenge assays for tetanus potency testing. Results suggest that the replacement standard is suitable for use as the reference vaccine in serological assays.

  9. Community and research staff collaboration for development of materials to inform microbicide study participants in Africa

    2014-09-01

    Full Text Available Introduction: Clinical trials of new vaginal products require careful communication with participants about trial requirements. Most microbicide trials have been multi-site studies conducted among women in sub-Saharan Africa, where literacy levels and understanding of scientific methods differ from those designing and conducting the trials. Microbicide trials require women to insert objects in their vagina and ensure they are present in the vagina during sex. For many women, this is a novel behaviour. These behaviours take place within the context of clinical trial participation, which is an additional novelty. Research teams must develop informational materials to help participants understand the clinical trial and input from local research staff and community members can improve the content and format of these materials. Methods: This paper discusses the development of illustrated materials developed for microbicide trial participants, presenting examples from two studies. In both studies, research staff and community advisory groups collaborated to review and revise materials. Results: Collaborative efforts revealed insights about how to convey information about clinical trial participation and microbicide use. These insights highlighted realities of the local context, details that might be misunderstood, illustrations of a sensitive nature and concerns about blood testing. In particular, information about blood testing and product use instructions required careful consideration. Although the research team anticipated needing advice on how best to convey information on these topics to participants, some aspects of potential participant concerns about these topics were also new to the research team. Community advisors and local research staff suggested better ways to convey this information, and provided guidance on how to use the materials. Conclusions: The collaboration served to develop informational materials for microbicide trial

This study investigates the subjective experiences of these tutors during the collaborative preparation and teaching of these tutorials with the aim of identifying the effects of equal participation in the perceptions and assessments of the other professional group.Method: Semi-structured, guideline-based interviews were held with six randomly selected tutors. The interviews were analyzed using structuring content analysis.Results: The results show that collaborative work led to reflection, mostly by the university student tutors, on the attitudes held. However, the co-tutors from each professional group were perceived to different degrees as being representative of those in their profession. Asked to master a shared assignment in a non-clinical context, the members of the different professional groups met on equal footing, even if the medical students had already gathered more teaching experience and thus mostly assumed a mentoring role over the course of working on and realizing the teaching units. The nursing tutors were primarily focused on their role as tutor. Both professional groups emphasized that prior to the collaboration they had an insufficient or no idea about the theoretical knowledge or practical skills of the other professional group. Overall, the project was rated as beneficial, and interprofessional education was endorsed.Conclusion: In the discussion, recommendations based on the insights are made for joint tutor training of both professional groups. According to these recommendations, harmonizing the teaching abilities of all tutors is essential to ensure equality during cooperation

  14. National collaborative shellfish pollution-indicator study: Site selection. Phase 2. Rept. for 1988-89

    Each year, about 16 million areas of estuarine waters are classified for the harvest of molluscan shellfish as open or limited to harvest according to microbiological 'indicator' standards and pollution survey guidelines established by the National Shellfish Sanitation Program. The program was developed in the 1920s in response to typhoid fever outbreaks associated with shellfish consumption. Current microbiological indicator standards in shellfish and shellfish-growing waters are extrpolated from standards set in the 1920s. Results from studies in the last decade have indicated that these microbiological indicator standards and thus classification of shellfish-growing waters may no longer be valid. The National Collaborative Shellfish Pollution Indicator Study is proposed as a four-year study to evaluate the current relationships between indicators of human enteric pathogens and the incidence of shellfish-borne diseases. Tasks forces were established to address specific issues, including site selection, shoreline surveys, and laboratory methodologies.

    This case study analyses the role of trust in a public private innovation network that involved a private consultancy company as a facilitator. We know that collaboration is a important for innovation, and that collaboration across organizational boundaries is not a trivial issue. But we know very...... little about how such processes develop and how trust, understood as “confident positive expectations” (Lewicki et al. 1998) to collaborative activities, arises out of collaboration. The paper contributes by showing how trust and collaboration are intertwined. The main finding is that a facilitator can...

    The study's aims are to explore ethnic differences in rates of adverse childhood experiences and lifetime traumatic events and in rates of psychiatric disorders for patients exposed to similar traumas. Rates of these events and rates of major depressive disorder, posttraumatic stress, substance use, and borderline personality disorders were compared among 506 non-Hispanic Whites (N-HW), 108 Latina(o)s, and 94 African Americans (AA) participating in the Collaborative Longitudinal Personality Disorder Study. We found that Whites reported higher rates of neglect than African Americans and Latina(o)s, higher rates of verbal/emotional abuse than African Americans, and higher rates of accidents and injuries/feared serious injury than Latina(o)s. African Americans had higher rates of seeing someone injured/killed than Whites. No significant interaction was observed between adverse events and ethnicity for mental disorders.

    The spiral plate count method is a semiautomated plating technique that greatly reduces manpower and material costs normally associated with the pour plating technique. In this collaborative study, 8 laboratories compared the spiral and pour plating techniques, using 4 samples each of 3 products: frozen pumpkin pie, frozen chicken pot pie, and shampoo. The results show that 10 of the 12 comparisons of means of the pour and spiral methods were not significantly different; 2 values were significant at alpha = 0.01. Overall, the components of variance were less than that of the current milk standard, and the replicate per cent coefficient of variation was satisfactory. This study indicates that the spiral plate method is an acceptable alternative to the pour plate method; the spiral plate method has been adopted as official first action.

    This is the second interim report jointly prepared by NASA and easyJet on the work performed under the agreement to collaborate on a study of the factors entailed in flight and cabin-crew fatigue, and decreases in performance associated with fatigue. The objective of this Agreement is to generate reliable procedures that aid in understanding the levels and characteristics of flight and cabin-crew fatigue factors, both latent and proximate, whose confluence will likely result in unacceptable crew performance. This study entails the analyses of numerical and textual data collected during operational flights. NASA and easyJet are both interested in assessing and testing NASA s automated capabilities for extracting operationally significant information from very large, diverse (textual and numerical) databases; much larger than can be handled practically by human experts.

    Genome-wide association studies (GWAS) have emerged as powerful means for identifying genetic loci related to complex diseases. However, the role of environment and its potential to interact with key loci has not been adequately addressed in most GWAS. Networks of collaborative studies involving different study populations and multiple phenotypes provide a powerful approach for addressing the challenges in analysis and interpretation shared across studies. The Gene, Environment Association Studies (GENEVA) consortium was initiated to: identify genetic variants related to complex diseases; identify variations in gene-trait associations related to environmental exposures; and ensure rapid sharing of data through the database of Genotypes and Phenotypes. GENEVA consists of several academic institutions, including a coordinating center, two genotyping centers and 14 independently designed studies of various phenotypes, as well as several Institutes and Centers of the National Institutes of Health led by the National Human Genome Research Institute. Minimum detectable effect sizes include relative risks ranging from 1.24 to 1.57 and proportions of variance explained ranging from 0.0097 to 0.02. Given the large number of research participants (N>80,000), an important feature of GENEVA is harmonization of common variables, which allow analyses of additional traits. Environmental exposure information available from most studies also enables testing of gene-environment interactions. Facilitated by its sizeable infrastructure for promoting collaboration, GENEVA has established a unified framework for genotyping, data quality control, analysis and interpretation. By maximizing knowledge obtained through collaborative GWAS incorporating environmental exposure information, GENEVA aims to enhance our understanding of disease etiology, potentially identifying opportunities for intervention.

    2015-01-01

    Background Historically, effectiveness of community collaborative prevention efforts has been mixed. Consequently, research has been undertaken to better understand the factors that support their effectiveness; theory and some related empirical research suggests that the provision of technical assistance is one important supporting factor. The current study examines one aspect of technical assistance that may be important in supporting coalition effectiveness, the collaborative relationship between the technical assistance provider and site lead implementer. Methods Four and one-half years of data were collected from technical assistance providers and prevention team members from the 14 community prevention teams involved in the PROSPER project. Results Spearman correlation analyses with longitudinal data show that the levels of the collaborative relationship during one phase of collaborative team functioning associated with characteristics of internal team functioning in future phases. Conclusions Results suggest that community collaborative prevention work should consider the collaborative nature of the technical assistance provider – prevention community team relationship when designing and conducting technical assistance activities, and it may be important to continually assess these dynamics to support high quality implementation.

    Full Text Available Abstract Background The appropriate level of oxygenation for extremely preterm neonates (90% have been reported to have greater rates of morbidity including retinopathy of prematurity and chronic lung disease. In order to answer this clinical dilemma reliably, large scale trial evidence is needed. Methods/Design To detect a small but important 4% increase in death or severe disability in survivors, over 5000 neonates would need to be recruited. As extreme prematurity affects 1% of births, such a project undertaken by one trial group would be prohibitively lengthy and expensive. Hence, the Neonatal Oxygenation Prospective Meta-analysis (NeOProM Collaboration has been formed. A prospective meta-analysis (PMA is one where studies are identified, evaluated, and determined to be eligible before the results of any included studies are known or published, thereby avoiding some of the potential biases inherent in standard, retrospective meta-analyses. This methodology provides the same strengths as a single large-scale multicentre randomised study whilst allowing greater pragmatic flexibility. The NeOProM Collaboration protocol (NCT01124331 has been agreed prior to the results of individual trials being available. This includes pre-specifying the hypotheses, inclusion criteria and outcome measures to be used. Each trial will first publish their respective results as they become available and the combined meta-analytic results, using individual patient data, will be published when all trials are complete. The primary outcome to be assessed is a composite outcome of death or major disability at 18 months - 2 years corrected age. Secondary outcomes include several measures of neonatal morbidity. The size of the combined dataset will allow the effect of the interventions to be explored more reliably with respect to pre-specified patient- and intervention-level characteristics. Discussion Results should be available by 2014.

    The Japan Collaborative Cohort Study for Evaluation of Cancer Risk (JACC Study) was established in the late 1980s to evaluate the risk impact of lifestyle factors and levels of serum components on human health. During the 20-year follow-up period, the results of the study have been published in almost 200 original articles in peer-reviewed English-language journals. However, continued follow-up of the study subjects became difficult because of the retirements of principal researchers, city mergers throughout Japan in the year 2000, and reduced funding. Thus, we decided to terminate the JACC Study follow-up at the end of 2009. As a final point of interest, we reviewed the population registry information of survivors. A total of 207 (0.19%) subjects were ineligible, leaving 110 585 eligible participants (46 395 men and 64 190 women). Moreover, errors in coding date of birth and sex were found in 356 (0.32%) and 59 (0.05%) cases, respectively, during routine follow-up and final review. Although such errors were unexpected, their impact is believed to be negligible because of the small numbers relative to the large total study population. Here, we describe the final cohort profile at the end of the JACC Study along with selected characteristics of the participants and their status at the final follow-up. Although follow-up of the JACC Study participants is finished, we will continue to analyze and publish study results.

  7. Patient-Specific Prosthetic Fingers by Remote Collaboration - A Case Study

    CERN Document Server

    Cabibihan, John-John

    2011-01-01

    The concealment of amputation through prosthesis usage can shield an amputee from social stigma and help improve the emotional healing process especially at the early stages of hand or finger loss. However, the traditional techniques in prosthesis fabrication defy this as the patients need numerous visits to the clinics for measurements, fitting and follow-ups. This paper presents a method for constructing a prosthetic finger through online collaboration with the designer. The main input from the amputee comes from the Computer Tomography (CT) data in the region of the affected and the non-affected fingers. These data are sent over the internet and the prosthesis is constructed using visualization, computer-aided design and manufacturing tools. The finished product is then shipped to the patient. A case study with a single patient having an amputated ring finger at the proximal interphalangeal joint shows that the proposed method has a potential to address the patient's psychosocial concerns and minimize the ...

Home-based everyday rehabilitation is a new interdisciplinary service for people living at home. Rehabilitation involves meeting the need for interprofessional services, interdisciplinary collaboration, and coordination of services. Everyday rehabilitation is a service that requires close interdisciplinary cooperation. The purpose of this study was to gain knowledge about employees' experiences with establishing a new multidisciplinary team and developing a team-based work model. Method: The study had a qualitative design using two focus group interviews with a newly established rehabilitation team. The sample consisted of an occupational therapist, two care workers with further education in rehabilitation, a nurse, a physiotherapist, and a project leader. Data were analyzed by thematic content analysis. Results: The data highlight three phases: a planning phase (ten meetings over half a year, a startup phase of trials of interdisciplinary everyday rehabilitation in practice (2 months, and a third period specifying and implementing an everyday rehabilitation model (6 months. During these phases, three themes emerged: 1 team creation and design of the service, 2 targeted practical trials, and 3 equality of team members and combining interdisciplinary methods. Conclusion: The team provided information about three processes: developing work routines and a revised team-based flow chart, developing team cooperation with integrated trans- and interdisciplinary collaboration, and working with external exchange. There is more need for secure network solutions. Keywords: everyday rehabilitation

    2016-11-01

    This article introduces a Special Section of case studies that focus on therapeutic collaboration and setbacks in the process of assimilation with the aim of contributing to the evolution of the assimilation model of therapeutic change. The first study examined setbacks in two depression cases (a good vs. a poor outcome) treated with emotion-focused therapy. The second article traced how therapist activities and positions toward internal voices were associated with setbacks in a case treated with linguistic therapy of evaluation. The third article studied contributions of therapeutic collaboration for both advances and setbacks in assimilation in two contrasting cases treated with emotion-focused therapy. The fourth and final article analyzed the therapeutic collaboration in episodes of ambivalence in two cases of narrative therapy (one good outcome, one poor outcome) reflecting on the implications for the assimilation model's perspective on the therapeutic relationship. This Introduction concludes by offering some suggestions for theory-building within the assimilation model.

    2009-10-01

    An international collaborative study (coded BSP083) was performed under the aegis of the Biological Standardisation Programme supported by the Council of Europe and the European Commission, with the aim of replacing the in vivo challenge assays for potency determination of combined acellular pertussis (aP) vaccines by a refined procedure also allowing reduction of animal use. This study investigates whether the immunogenicity of aP vaccine components could be assayed in a guinea pig (gp) serology model, using the same vaccine immunising doses as for D and T components potency testing, instead of using separate animals as is currently done. The BSP83 project is a follow up of 3 former collaborative studies (coded BSP019, BSP034 and BSP035) on serological methods for the potency testing of tetanus (T) and diphtheria (D) vaccines for human use. The use of gp instead of mice serology has the advantage of providing a larger volume of good quality antiserum for the assay of several vaccine components in the same sample, hence providing the opportunity for animal sparing. The results of Phase I of the study demonstrated that gp serology may be a useful method for the immunogenicity assay of acellular pertussis vaccines. This was confirmed in Phase II of the study, using 7 different combined aP vaccines in an international collaborative study involving 17 laboratories from both public and private sectors. Clear dose-response relationships were observed for different vaccines by ELISA, for antibodies against aP antigens, i.e. pertussis toxin (PT), filamentous haemagglutinin (FHA), fimbrial agglutinogens-2/3 (Fim 2/3) and pertactin (PRN). Intra- and inter-laboratory variations of aP ELISA results were found to be within an acceptable range. For some combined vaccines, however, the range of vaccine dilutions for immunisation confirmed to be optimal for D and T potency testing may not provide optimal dose-response for all aP components. Method adjustments may thus be required

    Hellman, Therese; Jensen, Irene; Bergström, Gunnar; Brämberg, Elisabeth Björk

    2016-05-01

    The aim of the study presented in this article was to explore how professionals, without guidelines for implementing interprofessional teamwork, experience the collaboration within team-based rehabilitation for people with back pain and how this collaboration influences their clinical practice. This study employed a mixed methods design. A questionnaire was answered by 383 participants and 17 participants were interviewed. The interviews were analysed using content analysis. The quantitative results showed that the participants were satisfied with their team-based collaboration. Thirty percent reported that staff changes in the past year had influenced their clinical practice, of which 57% reported that these changes had had negative consequences. The qualitative findings revealed that essential features for an effective collaboration were shared basic values and supporting each other. Furthermore, aspects such as having enough time for reflection, staff continuity, and a shared view of the team members' roles were identified as aspects which influenced the clinical practice. Important clinical implications for nurturing and developing a collaboration in team-based rehabilitation are to create shared basic values and a unified view of all team members' roles and their contributions to the team. These aspects need to be emphasised on an ongoing basis and not only when the team is formed.

    Relational and organisational factors are key elements of interprofessional collaboration (IPC) and team climate. Few studies have explored the relationship between IPC and team climate. This article presents a study that aimed to explore IPC in primary healthcare teams and understand how the assessment of team climate may provide insights into IPC. A mixed methods study design was adopted. In Stage 1 of the study, team climate was assessed using the Team Climate Inventory with 159 professionals in 18 interprofessional teams based in São Paulo, Brazil. In Stage 2, data were collected through in-depth interviews with a sample of team members who participated in the first stage of the study. Results from Stage 1 provided an overview of factors relevant to teamwork, which in turn informed our exploration of the relationship between team climate and IPC. Preliminary findings from Stage 2 indicated that teams with a more positive team climate (in particular, greater participative safety) also reported more effective communication and mutual support. In conclusion, team climate provided insights into IPC, especially regarding aspects of communication and interaction in teams. Further research will provide a better understanding of differences and areas of overlap between team climate and IPC. It will potentially contribute for an innovative theoretical approach to explore interprofessional work in primary care settings.

    Objective: The search for quality, cost-effective health care programs in the United States is now a major focus in the era of health care reform. New programs need to be evaluated as alternatives are developed in the health care system. The BirthPlace program provides comprehensive perinatal services with certified nurse-midwives and obstetricians working together in an integrated collaborative practice serving a primarily low-income population. Low-risk women are delivered by nurse-midwives in a freestanding birth center (The BirthPlace), which is one component of a larger integrated health network. All others are delivered by team obstetricians at the affiliated tertiary hospital. Wellness, preventive measures, early intervention, and family involvement are emphasized. The San Diego Birth Center Study is a 4-year research project funded by the U.S. Federal Agency for Health Care Policy and Research (#R01-HS07161) to evaluate this program. The National Birth Center Study (NEJM, 1989; 321(26): 1801-11) described the advantages and safety of freestanding birth centers. However, a prospective cohort study with a concurrent comparison group of comparable risk had not been conducted on a collaborative practice-freestanding birth center model to address questions of safety, cost, and patient satisfaction.Methods: The specific aims of this study are to compare this collaborative practice model to the traditional model of perinatal health care (physician providers and hospital delivery). A prospective cohort study comparing these two health care models was conducted with a final expected sample size of approximately 2,000 birth center and 1,350 traditional care subjects. Women were recruited from both the birth center and traditional care programs (private physicians offices and hospital based clinics) at the beginning of prenatal care and followed through the end of the perinatal period. Prenatal, intrapartum, postpartum and infant morbidity and mortality are being

    Full Text Available Abstract Background Collaborative, culturally safe services that integrate clinical approaches with traditional Aboriginal healing have been hailed as promising approaches to ameliorate the high rates of mental health problems in Aboriginal communities in Canada. Overcoming significant financial and human resources barriers, a mental health team in northern Ontario is beginning to realize this ideal. We studied the strategies, strengths and challenges related to collaborative Aboriginal mental health care. Methods A participatory action research approach was employed to evaluate the Knaw Chi Ge Win services and their place in the broader mental health system. Qualitative methods were used as the primary source of data collection and included document review, ethnographic interviews with 15 providers and 23 clients; and 3 focus groups with community workers and managers. Results The Knaw Chi Ge Win model is an innovative, community-based Aboriginal mental health care model that has led to various improvements in care in a challenging rural, high needs environment. Formal opportunities to share information, shared protocols and ongoing education support this model of collaborative care. Positive outcomes associated with this model include improved quality of care, cultural safety, and integration of traditional Aboriginal healing with clinical approaches. Ongoing challenges include chronic lack of resources, health information and the still cursory understanding of Aboriginal healing and outcomes. Conclusions This model can serve to inform collaborative care in other rural and Indigenous mental health systems. Further research into traditional Aboriginal approaches to mental health is needed to continue advances in collaborative practice in a clinical setting.

    Today interprofessional education (IPE) is spread throughout the world. In Sweden only one of the existing nursing programs has an IPE curriculum on several levels during the training. The aim of this study was to examine how nurses who recently graduated from universities with IPE or non-IPE curricula perceive the importance of different educational goals and whether they found themselves prepared for their profession, and especially for collaboration with other professions. Three universities with different commitments to IPE were studied. We used a survey with eight different targets: communication skills, cooperation with other professions, problem-solving capability, self-directed learning skills, whether their education has prepared them to work professionally, to perform research, to take care of acutely ill patients, to work preventively and working as a nurse. The participants were asked whether their undergraduate education had prepared them for these targets and whether they perceived that the targets were important goals for their education. A main result in this study was that nurses who had recently graduated from the IPE university perceived to a greater extent that their undergraduate training had prepared them to work together with other professions in comparison with nursing students from non-IPE universities.

    Full Text Available Abstract Background The scientific process around cancer research begins with scientific discovery, followed by development of interventions, and finally delivery of needed interventions to people with cancer. Numerous studies have identified substantial gaps between discovery and delivery in health research. Team science has been identified as a possible solution for closing the discovery to delivery gap; however, little is known about effective ways of collaborating within teams and across organizations. The purpose of this study was to determine benefits and drawbacks associated with organizational collaboration across the discovery-development-delivery research continuum. Methods Representatives of organizations working on cancer research across a state answered a survey about how they collaborated with other cancer research organizations in the state and what benefits and drawbacks they experienced while collaborating. We used exponential random graph modeling to determine the association between these benefits and drawbacks and the presence of a collaboration tie between any two network members. Results Different drawbacks and benefits were associated with discovery, development, and delivery collaborations. The only consistent association across all three was with the drawback of difficulty due to geographic differences, which was negatively associated with collaboration, indicating that those organizations that had collaborated were less likely to perceive a barrier related to geography. The benefit, enhanced access to other knowledge, was positive and significant in the development and delivery networks, indicating that collaborating organizations viewed improved knowledge exchange as a benefit of collaboration. ‘Acquisition of additional funding or other resources’ and ‘development of new tools and methods’ were negatively significantly related to collaboration in these networks. So, although improved knowledge access was an

    Full Text Available Distance education has been offered to young students in Australia for about 100 years. Recently, information and communication technology has been introduced as a means to improve communication, but not all remote students have access to this new technology. This has made it difficult to arrange collaborative learning for distance-education students. In this student-focused study, more than 40 students as well as teachers and other important persons have been interviewed and observed in schools and on remote farms. Using Activity Theory for the analysis, different contradictions were identified. Lack of technology and access were not the only obstacles. The education was built on a tradition of individual learning, and the technology at hand was not supporting collaboration. However, contradictions may result in ‘expansive learning’ among students and teachers, leading to more of a development towards collaborative learning.

    Pathway is designed to help develop the scientific basis for understanding and predicting long-term environmental degradation behavior of materials in nuclear power plants and to provide data and methods to assess performance of systems, structures, and components essential to safe and sustained operation. The Risk-Informed Safety Margins Characterization Pathway (RISMC) seeks to merge fundamental scientific understanding of critical phenomenological conditions and deterministic predictions of nuclear power plant performance with risk-informed characterization tools. This will provide an integrated characterization of public safety margins in an optimization of nuclear safety, plant performance, and long-term asset management. Clearly, these two pathways have many synergies in goals and outcomes. The data and mechanisms generated in the Materials Pathway may feed into and mold efforts within the RISMC Pathway. In addition, insights from the characterization tools developed in RISMC tasks may inform materials testing needs and experiments. To demonstrate this potentially powerful interaction, a joint case study has been proposed and initiated. This document describes the initial planning for a coordinated study between the Materials and the RISMC Pathways. A brief description of each Pathway is presented along with a more detailed description of the needs and requirements of this collaborative task. A list of criteria for any case-study candidate are then listed, along with the rationale for choosing pressurized thermal shock as the prime candidate an inter-pathway collaboration. A proposed timeline and organization of future interactions on this subject area is also presented.

    2017-01-01

    Introduction For over a decade, enquiries into adverse perinatal outcomes have led to reports that poor collaboration has been detrimental to the safety and experience of maternity care. Despite efforts to improve collaboration, investigations into maternity care at Morecambe Bay (UK) and Djerriwarrh Health Services (Australia) have revealed that poor collaboration and decision-making remain a threat to perinatal safety. The Labouring Together study will investigate how elements hypothesised to influence the effectiveness of collaboration are reflected in perceptions and experiences of clinicians and childbearing women in Victoria, Australia. The study will explore conditions that assist clinicians and women to work collaboratively to support positive maternity outcomes. Results of the study will provide a platform for consumers, clinician groups, organisations and policymakers to work together to improve the quality, safety and experience of maternity care. Methods and analysis 4 case study sites have been selected to represent a range of models of maternity care in metropolitan and regional Victoria, Australia. A mixed-methods approach including cross-sectional surveys and interviews will be used in each case study site, involving both clinicians and consumers. Quantitative data analysis will include descriptive statistics, 2-way multivariate analysis of variance for the dependent and independent variables, and χ2 analysis to identify the degree of congruence between consumer preferences and experiences. Interview data will be analysed for emerging themes and concepts. Data will then be analysed for convergent lines of enquiry supported by triangulation of data to draw conclusions. Ethics and dissemination Organisational ethics approval has been received from the case study sites and Deakin University Human Research Ethics Committee (2014–238). Dissemination of the results of the Labouring Together study will be via peer-reviewed publications and conference

    In 1996, U.S. Food and Drug Administration regulations mandated the fortification of enriched cereal-grain products with folic acid, thereby emphasizing the need for validated methods for total folates in foods, particularly cereal products. The AOAC Official Methods (944.12, 960.46) currently used for the analysis of folate in foods for compliance purposes are microbiological methods. When the fortification regulations were finalized, no Official AOAC or Approved AACC methods for folate in cereal-grain products were in place. The AOAC Official Method (992.05) for folic acid in infant formula does not incorporate important improvements in the extraction procedure and was not considered suitable for the analysis of folates in foods in general. A microbiological assay protocol using a trienzyme extraction procedure was prepared and submitted for comments to 40 laboratories with recognized experience in folate analysis. On the basis of comments, the method was revised to have the conjugase (gamma-glutamyl-carboxy-peptidase) treatment follow a protease treatment, to include the use of cryoprotected inoculum, and to include the spectroscopic standardization of the standard and optional use of microtiter plates. Thirteen laboratories participated in a collaborative study of 10 required and 10 optional cereal-grain products, including flour, bread, cookies, baking mixes, and ready-to-eat breakfast cereals. The majority of the participating laboratories performed the assay by the standard test tube method; others used the microtiter plate modification for endpoint quantitation with equal success. For the required products, the relative standard deviation between laboratories (RSD(R)) ranged from 7.4 to 21.6% for 8 fortified (or enriched) products compared with expected (Horwitz equation-based) values of 11-20%. RSD(R) values were higher (22.7-52.9%) for 2 unfortified cereal-grain products. For the optional products, the RSD(R) ranged from 1.8 to 11.2% for 8 fortified

    This project was part of a collaborative campaign, including the participation of scientists from seven research groups as part of the Winter Intensive Operating Period (January-February 2012) of the Clean Air for London (ClearfLo) campaign at a rural site in Detling, UK, 45 km southeast of central London to study wintertime sources of urban particulate matter. The UW contribution by PI Thornton’s group was to make the first deployment of a chemical ionization mass spectrometer instrument (MOVI-CI-ToFMS) to measure both particle and gas phase organic acids. The new instrument ran nearly continuously during the ClearfLo WINTER IOP at the Detling site, producing a first-ever data set of molecular composition information that can be used for source apportionment and process studies. The UW group published a paper in Environmental Science and Technology and contributed to another (Bohnenstengel et al BAMS 2015) detailing a direct molecular connection between biomass/biofuel burning particles and aerosol light absorption. The ES&T paper (Mohr, et al ES&T 2013) has received 42 citations in just 3 years indicative of its significant impact on the field. These measurements of urban and rural aerosol properties will contribute to improved modeling of regional aerosol emissions, and of atmospheric aging and removal.

    2014-01-01

    Gene therapy products are expected as innovative medicinal products for intractable diseases such as life-threatening genetic diseases and cancer. Recently, clinical developments by pharmaceutical companies are accelerated in Europe and the United States, and the first gene therapy product in advanced countries was approved for marketing authorization by the European Commission in 2012. On the other hand, more than 40 clinical studies for gene therapy have been completed or ongoing in Japan, most of them are conducted as clinical researches by academic institutes, and few clinical trials have been conducted for approval of gene therapy products. In order to promote the development of gene therapy products, revision of the current guideline and/or preparation of concept paper to address the evaluation of the quality and safety of gene therapy products are necessary and desired to clearly show what data should be submitted before First-in-Human clinical trials of novel gene therapy products. We started collaborative study with academia and regulatory agency to promote regulatory science toward clinical development of gene therapy products for genetic diseases based on lentivirus and adeno-associated virus vectors; National Center for Child Health and Development (NCCHD), Nippon Medical School and PMDA have been joined in the task force. At first, we are preparing pre-draft of the revision of the current gene therapy guidelines in this project.

    Background Due to the rarity of adenoid cystic carcinoma (ACC), information on outcome is based upon small retrospective case series. The aim of our study was to create a large multiinstitutional international dataset of patients with ACC in order to design predictive nomograms for outcome. Methods ACC patients managed at 10 international centers were identified. Patient, tumor, and treatment characteristics were recorded and an international collaborative dataset created. Multivariable competing risk models were then built to predict the 10 year recurrence free probability (RFP), distant recurrence free probability (DRFP), overall survival (OS) and cancer specific mortality (CSM). All predictors of interest were added in the starting full models before selection, including age, gender, tumor site, clinical T stage, perineural invasion, margin status, pathologic N-status, and M-status. Stepdown method was used in model selection to choose predictive variables. An external dataset of 99 patients from 2 other institutions was used to validate the nomograms. Findings Of 438 ACC patients, 27.2% (119/438) died from ACC and 38.8% (170/438) died of other causes. Median follow-up was 56 months (range 1–306). The nomogram for OS had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N-status and M-status) with a concordance index (CI) of 0.71. The nomogram for CSM had the same variables, except margin status, with a concordance index (CI) of 0.70. The nomogram for RFP had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N status and perineural invasion) (CI 0.66). The nomogram for DRFP had 6 variables (gender, clinical T stage, tumor site, pathologic N-status, perineural invasion and margin status) (CI 0.64). Concordance index for the external validation set were 0.76, 0.72, 0.67 and 0.70 respectively. Interpretation Using an international collaborative database we have created the first nomograms which

    2008-03-01

    The challenge for members of interprofessional teams is to manage the team processes that occur in all teamwork while simultaneously managing their individual professional identities. The aim of this study was to identify and describe difficulties perceived by health professionals in interprofessional teamwork. Utterances on verbal actions and resolutions were also explored to enable a discussion of the implications for interprofessional learning. Individual interviews using a Critical Incident Technique were performed with 18 Swedish professionals working in healthcare teams, and examined with qualitative content analysis. The main findings show difficulties related to the team dynamic that arose when team members acted towards one another as representatives of their professions, difficulties that occurred when the members' various knowledge contributions interacted in the team, and difficulties related to the influence of the surrounding organization. The perceived consequences of the difficulties, beyond individual consequences, were restrictions on the use of collaborative resources to arrive at a holistic view of the patient's problem, and barriers to providing patient care and service in the desired manner. This paper also discusses how experiences of managing difficulties entailed various forms of interprofessional learning situations.

    The Collaborative Lubricating Oil Study on Emissions (CLOSE) project was a pilot investigation of how fuels and crankcase lubricants contribute to the formation of particulate matter (PM) and semi-volatile organic compounds (SVOC) in vehicle exhaust. As limited vehicles were tested, results are not representative of the whole on-road fleet. Long-term effects were not investigated. Pairs of vehicles (one normal PM emitting, one high-PM emitting) from four categories were selected: light-duty (LD) gasoline cars, medium-duty (MD) diesel trucks, heavy-duty (HD) natural-gas-fueled buses, and HD diesel buses. HD vehicles procured did not exhibit higher PM emissions, and thus were labeled high mileage (HM). Fuels evaluated were non-ethanol gasoline (E0), 10 percent ethanol (E10), conventional low-sulfur TxLED diesel, 20% biodiesel (B20), and natural gas. Temperature effects (20 degrees F, 72 degrees F) were evaluated on LD and MD vehicles. Lubricating oil vintage effects (fresh and aged) were evaluated on all vehicles. LD and MD vehicles were operated on a dynamometer over the California Unified Driving Cycle, while HD vehicles followed the Heavy Duty Urban Dynamometer Driving Schedule. Regulated and unregulated emissions were measured. Chemical markers from the unregulated emissions measurements and a tracer were utilized to estimate the lubricant contribution to PM.

    1996-11-01

    Varicella vaccine in immunocompromised children was clinically evaluated in 575 US and Canadian children with leukemia in remission by the Varicella Vaccine Collaborative Study. Most children had chemotherapy stopped 1 week before and 1 week after immunization. Steroids were stopped for 3 weeks (1 week before to 2 weeks after vaccination). Varicella vaccine was safe, immunogenic, and effective in leukemic children at risk for serious disease or death from chickenpox. The major side effect was mild rash in 50% approximately 1 month after immunization. About 40% of children who developed rash were treated with acyclovir. Vaccine efficacy was judged by the degree of protection after a household exposure to varicella; of 123 exposed children, 17 (14%) developed a mild form of varicella. The vaccine protected completely against severe varicella. Leukemic vaccines were less likely to develop zoster than were comparable children with leukemia who had wild type varicella. Thus, varicella vaccine, administered carefully with close follow-up, is extremely beneficial for leukemic children.

  11. Patient-specific prosthetic fingers by remote collaboration--a case study.

    Directory of Open Access Journals (Sweden)

    John-John Cabibihan

    Full Text Available The concealment of amputation through prosthesis usage can shield an amputee from social stigma and help improve the emotional healing process especially at the early stages of hand or finger loss. However, the traditional techniques in prosthesis fabrication defy this as the patients need numerous visits to the clinics for measurements, fitting and follow-ups. This paper presents a method for constructing a prosthetic finger through online collaboration with the designer. The main input from the amputee comes from the Computer Tomography (CT data in the region of the affected and the non-affected fingers. These data are sent over the internet and the prosthesis is constructed using visualization, computer-aided design and manufacturing tools. The finished product is then shipped to the patient. A case study with a single patient having an amputated ring finger at the proximal interphalangeal joint shows that the proposed method has a potential to address the patient's psychosocial concerns and minimize the exposure of the finger loss to the public.

    Traditionally, evaluation methods in the field of semantic technologies have focused on the end result of ontology engineering efforts, mainly, on evaluating ontologies and their corresponding qualities and characteristics. This focus has led to the development of a whole arsenal of ontology-evaluation techniques that investigate the quality of ontologies as a product. In this paper, we aim to shed light on the process of ontology engineering construction by introducing and applying a set of measures to analyze hidden social dynamics. We argue that especially for ontologies which are constructed collaboratively, understanding the social processes that have led to its construction is critical not only in understanding but consequently also in evaluating the ontology. With the work presented in this paper, we aim to expose the texture of collaborative ontology engineering processes that is otherwise left invisible. Using historical change-log data, we unveil qualitative differences and commonalities between different collaborative ontology engineering projects. Explaining and understanding these differences will help us to better comprehend the role and importance of social factors in collaborative ontology engineering projects. We hope that our analysis will spur a new line of evaluation techniques that view ontologies not as the static result of deliberations among domain experts, but as a dynamic, collaborative and iterative process that needs to be understood, evaluated and managed in itself. We believe that advances in this direction would help our community to expand the existing arsenal of ontology evaluation techniques towards more holistic approaches.

    Full Text Available Abstract Background Bottom-up, clinician-conceived and directed clinical intervention research, coupled with collaboration from researcher experts, is conceptually endorsed by the participatory research movement. This report presents the findings of an evaluation of a program in the Veterans Health Administration meant to encourage clinician-driven research by providing resources believed to be critical. The evaluation focused on the extent to which funded projects: maintained integrity to their original proposals; were methodologically rigorous; were characterized by collaboration between partners; and resulted in sustained clinical impact. Methods Researchers used quantitative (survey and archival and qualitative (focus group data to evaluate the implementation, evaluation, and sustainability of four clinical demonstration projects at four sites. Fourteen research center mentors and seventeen clinician researchers evaluated the level of collaboration using a six-dimensional model of participatory research. Results Results yielded mixed findings. Qualitative and quantitative data suggested that although the process was collaborative, clinicians' prior research experience was critical to the quality of the projects. Several challenges were common across sites, including subject recruitment, administrative support and logistics, and subsequent dissemination. Only one intervention achieved lasting clinical effect beyond the active project period. Qualitative analyses identified barriers and facilitators and suggested areas to improve sustainability. Conclusions Evaluation results suggest that this participatory research venture was successful in achieving clinician-directed collaboration, but did not produce sustainable interventions due to such implementation problems as lack of resources and administrative support.

    Full Text Available Since the 1990s, the theme of participation has come to the fore in international debates regarding at least three critical issues: the relationship between representative democracy and deliberative democracy and the possibility of citizens’ empowerment through their involvement in policy making; the role of communication and of digital media in promoting new forms of participation; the feeling of disaffection toward politics and of democratic deficit. What we observe is a proliferation of experiences of both bottom-up and top-down enhanced forms of civic engagement. Our article focuses on “public engagement.” We analyze the civic collaboration policy promoted by the Municipality of Bologna (Italy in the frame of “collaborative governance” of the commons, based on civic involvement and governance transparency. Civic collaboration is characterized by a mixed communication ecology. We focus on the inclusiveness of this form of public engagement with local policies and on the role of digital media in supporting citizen’s engagement. Civic collaboration emerges as a new, interesting frontier in top-down enhanced participation in local policies. We are currently witnessing some promising changes in the boundaries of participation, in civic practices and competencies. In conclusion, we argue that the concreteness of the projects of civic collaboration can enhance citizens’ trust in the municipal administration, but we wonder whether it is likely to become a substitute for fuller citizen participation in local governance and whether it could also foster a removal of the controversial dimension of the political.

    Full Text Available We examined clinicians’ and researchers’ experiences from participation in collaborative research on the introduction of Internet and mobile information systems (mHealth systems in psychotherapeutic routines. The study used grounded theory methodology and was set in a collaboration that aimed to develop and evaluate mHealth support of psychotherapy provided to young people. Soundness of the central objects developed in the design phase (the collaboration contract, the trial protocol, and the system technology was a necessary foundation for successful collaborative mHealth research; neglect of unanticipated organizational influences during the trial phase was a factor in collaboration failure. The experiences gained in this study can be used in settings where collaborative research on mHealth systems in mental health is planned.

    Twelve laboratories participated in a collaborative study to compare a combustion method with the AOAC mercury catalyst Kjeldahl method (928.08) for the determination of crude protein in meat and meat products. Three different combustion instruments were used; consequently, the combustion method for this study is written in generic terms describing the principle, the apparatus specifications, and the performance requirements needed. Fifteen sample pairs were used for the study; each pair consisted of the same commercial meat product from each of 2 different manufacturers. Protein content of all samples ranged from about 10 to 20%. In addition, nicotinic acid and lysine monohydrochloride were used as standards to assess combustion equipment performance. All laboratories and all instruments performed the combustion method satisfactorily on the basis of results for the standards. For the meat samples, repeatability standard deviations (Sr) ranged from 0.11 to 0.40 for the Kjeldahl method and from 0.12 to 0.41 for the combustion method; the repeatability relative standard deviations (RSDr) ranged from 0.82 to 2.41% and from 0.60 to 2.23% for the Kjeldahl and combustion methods, respectively. Reproducibility standard deviations (SR) ranged from 0.20 to 0.49 for the Kjeldahl method and from 0.18 to 0.46 for the combustion method, whereas the reproducibility relative standard deviations (RSDR) ranged from 1.59 to 2.84% for the Kjeldahl method and from 1.32 to 3.35% for the combustion method. Overall grand means were 15.59% protein for the Kjeldahl method and 15.75% protein for the combustion method. The combustion method was adopted first action by AOAC International.

    China Fusion Engineering Test Reactor (CFETR) is an ITER-like superconducting tokamak device and it is under conceptual design. The paper is to highlight the building of the collaborative platform and its application in design work. First, a collaborative framework between collaborators is proposed and a method based-on Riverbed to optimize WAN is adopted to improve the data transmission. Then it proposes a Unified Modeling Language (UML) approach for specification of PDM (Product Documents Management) system implementation to enable management of whole product data and related information about its entire lifecycle. At last, the chosen approach for modeling based on UML is detailed and the relational design based-on skeleton is instanced for CFETR.

  18. Student use of a Learning Management System for group projects: A case study investigating interaction, collaboration, and knowledge construction

    Science.gov (United States)

    Lonn, Steven D.

    Web-based Learning Management Systems (LMS) allow instructors and students to share instructional materials, make class announcements, submit and return course assignments, and communicate with each other online. Previous LMS-related research has focused on how these systems deliver and manage instructional content with little concern for how students' constructivist learning can be encouraged and facilitated. This study investigated how students use LMS to interact, collaborate, and construct knowledge within the context of a group project but without mediation by the instructor. The setting for this case study was students' use in one upper-level biology course of the local LMS within the context of a course-related group project, a mock National Institutes of Health grant proposal. Twenty-one groups (82 students) voluntarily elected to use the LMS, representing two-thirds of all students in the course. Students' peer-to-peer messages within the LMS, event logs, online surveys, focus group interviews, and instructor interviews were used in order to answer the study's overarching research question. The results indicate that students successfully used the LMS to interact and, to a significant extent, collaborate, but there was very little evidence of knowledge construction using the LMS technology. It is possible that the ease and availability of face-to-face meetings as well as problems and limitations with the technology were factors that influenced whether students' online basic interaction could be further distinguished as collaboration or knowledge construction. Despite these limitations, students found several tools and functions of the LMS useful for their online peer interaction and completion of their course project. Additionally, LMS designers and implementers are urged to consider previous literature on computer-supported collaborative learning environments in order to better facilitate independent group projects within these systems. Further research is

    1996-07-01

    The major cause of hyperphenylalaninemia is mutations in the gene encoding phenylalanine hydroxylase (PAH). The known mutations have been identified primarily in European patients. The purpose of this study was to determine the spectrum of mutations responsible for PAH deficiency in the United States. One hundred forty-nine patients enrolled in the Maternal PKU Collaborative Study were subjects for clinical and molecular investigations. PAH gene mutations associated with phenylketonuria (PKU) or mild hyperphenylalaninemia (MHP) were identified on 279 of 294 independent mutant chromosomes, a diagnostic efficiency of 95%. The spectrum is composed of 71 different mutations, including 47 missense mutations, 11 splice mutations, 5 nonsense mutations, and 8 microdeletions. Sixteen previously unreported mutations were identified. Among the novel mutations, five were found in patients with MHP, and the remainder were found in patients with PKU. The most common mutations were R408W, IVS12nt1g{r_arrow}a, and Y414C, accounting for 18.7%, 7.8% and 5.4% of the mutant chromosomes, respectively. Thirteen mutations had relative frequencies of 1%-5%, and 55 mutations each had frequencies {le}1%. The mutational spectrum corresponded to that observed for the European ancestry of the U.S. population. To evaluate the extent of allelic variation at the PAH locus within the United States in comparison with other populations, we used allele frequencies to calculate the homozygosity for 11 populations where >90% ascertainment has been obtained. The United States was shown to contain one of the most heterogeneous populations, with homozygosity values similar to Sicily and ethnically mixed sample populations in Europe. The extent of allelic heterogeneity must be a major determining factor in the choice of mutation-detection methodology for molecular diagnosis in PAH deficiency. 47 refs., 1 fig., 5 tabs.

    Full Text Available Background Although collaborative team models (CTM improve care processes and health outcomes, their diffusion poses challenges related to difficulties in securing their adoption by primary care clinicians (PCPs. The objectives of this study are to understand: (1 how the perceived characteristics of a CTM influenced clinicians' decision to adopt -or not- the model; and (2 the model's diffusion process. Methods We conducted a longitudinal case study based on the Diffusion of Innovations Theory. First, diffusion curves were developed for all 175 PCPs and 59 nurses practicing in one borough of Paris. Second, semi-structured interviews were conducted with a representative sample of 40 PCPs and 15 nurses to better understand the implementation dynamics. Results Diffusion curves showed that 3.5 years after the start of the implementation, 100% of nurses and over 80% of PCPs had adopted the CTM. The dynamics of the CTM's diffusion were different between the PCPs and the nurses. The slopes of the two curves are also distinctly different. Among the nurses, the critical mass of adopters was attained faster, since they adopted the CTM earlier and more quickly than the PCPs. Results of the semi-structured interviews showed that these differences in diffusion dynamics were mostly founded in differences between the PCPs' and the nurses' perceptions of the CTM's compatibility with norms, values and practices and its relative advantage (impact on patient management and work practices. Opinion leaders played a key role in the diffusion of the CTM among PCPs. Conclusion CTM diffusion is a social phenomenon that requires a major commitment by clinicians and a willingness to take risks; the role of opinion leaders is key. Paying attention to the notion of a critical mass of adopters is essential to developing implementation strategies that will accelerate the adoption process by clinicians.

  2. A case study in the participatory design of a collaborative science-based learning environment

    Science.gov (United States)

    Chin, George, Jr.

    Educational technology research studies have found computer and software technologies to be underutilized in U.S. classrooms. In general, many teachers have had difficulty integrating computer and software technologies into learning activities and classroom curriculums because specific technologies are ill-suited to their needs, or they lack the ability to make effective use of these technologies. In the development of commercial and business applications, participatory design approaches have been applied to facilitate the direct participation of users in system analysis and design. Among the benefits of participatory design include mutual learning between users and developers, envisionment of software products and their use contexts, empowerment of users in analysis and design, grounding of design in the practices of users, and growth of users as designers and champions of technology. In the context of educational technology development, these similar consequences of participatory design may lead to more appropriate and effective education systems as well as greater capacities by teachers to apply and integrate educational systems into their teaching and classroom practices. We present a case study of a participatory design project that took place over a period of two and one half years, and in which teachers and developers engaged in the participatory analysis and design of a collaborative science learning environment. A significant aspect of the project was the development methodology we followed---Progressive Design. Progressive Design evolved as an integration of methods for participatory design, ethnography, and scenario-based design. In this dissertation, we describe the Progressive Design approach, how it was used, and its specific impacts and effects on the development of educational systems and the social and cognitive growth of teachers.

    In 2004, NASA faced major knowledge sharing challenges due to geographically isolated field centers that inhibited personnel from sharing experiences and ideas. Mission failures and new directions for the agency demanded better collaborative tools. In addition, with the push to send astronauts back to the moon and to Mars, NASA recognized that systems engineering would have to improve across the agency. Of the ten field centers, seven had not built a spacecraft in over 30 years, and had lost systems engineering expertise. The Systems Engineering Community of Practice came together to capture the knowledge of its members using the suite of collaborative tools provided by the NASA Engineering Network (NEN.) The NEN provided a secure collaboration space for over 60 practitioners across the agency to assemble and review a NASA systems engineering handbook. Once the handbook was complete, they used the open community area to disseminate it. This case study explores both the technology and the social networking that made the community possible, describes technological approaches that facilitated rapid setup and low maintenance, provides best practices that other organizations could adopt, and discusses the vision for how this community will continue to collaborate across the field centers to benefit the agency as it continues exploring the solar system.

  7. Mechanism and technology study of collaborative support with long and short bolts in large-deformation roadways

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

    The animal and plant biodiversity of the Italian territory is known to be one of the richest in the Mediterranean basin and Europe as a whole, but does the genetic diversity of extant human populations show a comparable pattern? According to a number of studies, the genetic structure of Italian populations retains the signatures of complex peopling processes which took place from the Paleolithic to modern era. Although the observed patterns highlight a remarkable degree of genetic heterogeneity, they do not, however, take into account an important source of variation. In fact, Italy is home to numerous ethnolinguistic minorities which have yet to be studied systematically. Due to their difference in geographical origin and demographic history, such groups not only signal the cultural and social diversity of our country, but they are also potential contributors to its bio-anthropological heterogeneity. To fill this gap, research groups from four Italian Universities (Bologna, Cagliari, Pisa and Roma Sapienza) started a collaborative study in 2007, which was funded by the Italian Ministry of Education, University and Research and received partial support by the Istituto Italiano di Antropologia. In this paper, we present an account of the results obtained in the course of this initiative. Four case-studies relative to linguistic minorities from the Eastern Alps, Sardinia, Apennines and Southern Italy are first described and discussed, focusing on their micro-evolutionary and anthropological implications. Thereafter, we present the results of a systematic analysis of the relations between linguistic, geographic and genetic isolation. Integrating the data obtained in the course of the long-term study with literature and unpublished results on Italian populations, we show that a combination of linguistic and geographic factors is probably responsible for the presence of the most robust signatures of genetic isolation. Finally, we evaluate the magnitude of the diversity

    Repeat episodes of infective endocarditis (IE) can occur in patients who survive an initial episode. We analysed risk factors and 1-year mortality of patients with repeat IE. We considered 1874 patients enrolled in the International Collaboration on Endocarditis - Prospective Cohort Study between January 2000 and December 2006 (ICE-PCS) who had definite native or prosthetic valve IE and 1-year follow-up. Multivariable analysis was used to determine risk factors for repeat IE and 1-year mortality. Of 1874 patients, 1783 (95.2%) had single-episode IE and 91 (4.8%) had repeat IE: 74/91 (81%) with new infection and 17/91 (19%) with presumed relapse. On bivariate analysis, repeat IE was associated with haemodialysis (p 0.002), HIV (p 0.009), injection drug use (IDU) (p < 0.001), Staphylococcus aureus IE (p 0.003), healthcare acquisition (p 0.006) and previous IE before ICE enrolment (p 0.001). On adjusted analysis, independent risk factors were haemodialysis (OR, 2.5; 95% CI, 1.2-5.3), IDU (OR, 2.9; 95% CI, 1.6-5.4), previous IE (OR, 2.8; 95% CI, 1.5-5.1) and living in the North American region (OR, 1.9; 95% CI, 1.1-3.4). Patients with repeat IE had higher 1-year mortality than those with single-episode IE (p 0.003). Repeat IE is associated with IDU, previous IE and haemodialysis. Clinicians should be aware of these risk factors in order to recognize patients who are at risk of repeat IE.

    The subject of ethics in science has become a hot topic recently (Gleick, 2011). As publication pressure on researchers increases and use of the internet allows faster turn-around, the quality of the peer review process has suffered. This presentation describes one case of scientific ethics violation in which the editors of a high-ranking scientific journal improperly permitted publication of a paper that was based upon unethical acquisition of data and failed to acknowledge scientific collaboration and exchange of intellectual property. We will present "Case description" and "Ethical issues" with a hope that our experience draws attention to important ethical issues in international collaborative research, and prevents such misconduct in the future. Since international research involves cooperation and coordination among many people in different disciplines and institutions across national borders, ethical standards should promote values that are essential to integrity and collaborative work, including trust, accountability, mutual respect, and fairness. One lesson to be learned is not to engage in collaboration without a written agreement stating clearly who is responsible for what and how the results of collaborative research are to be shared. This is especially important in cases of international collaborations, particularly those involving smaller or developing nations who often do not have the high-tech facilities of developed nations. There is also need to establish clear regulations regarding co-authorship on papers in which intellectual property and significant financial investment was made to allow the research to proceed. As such, a system of ethics to guide the practice of science from data collection to publication and beyond is timely and much needed to protect the integrity of scientific collaboration. It will keep science moving forward by validating research findings and confirming or raising questions about results. References Benos, D. J., Fabres

    The primary goal of the Consortium for the Advancement of Shape Memory Alloy Research and Technology (CASMART) is to enable the design of revolutionary applications based on shape memory alloy (SMA) technology. In order to help realize this goal and reduce the development time and required experience for the fabrication of SMA actuation systems, several modeling tools have been developed for common actuator types and are discussed herein along with case studies, which highlight the capabilities and limitations of these tools. Due to their ability to sustain high stresses and recover large deformations, SMAs have many potential applications as reliable, lightweight, solid-state actuators. Their advantage over classical actuators can also be further improved when the actuator geometry is modified to fit the specific application. In this paper, three common actuator designs are studied: wires, which are lightweight, low-profile, and easily implemented; springs, which offer actuation strokes upwards of 200 at reduced mechanical loads; and torque tubes, which can provide large actuation forces in small volumes and develop a repeatable zero-load actuation response (known as the two-way shape memory effect). The modeling frameworks, which have been implemented in the design tools, are developed for each of these frequently used SMA actuator types. In order to demonstrate the versatility and flexibility of the presented design tools, as well as validate their modeling framework, several design challenges were completed. These case studies include the design and development of an active hinge for the deployment of a solar array or foldable space structure, an adaptive solar array deployment and positioning system, a passive air temperature controller for regulation flow temperatures inside of a jet engine, and a redesign of the Corvette active hatch, which allows for pressure equalization of the car interior.

    A WHO collaborative study on viral hepatitis B in which 21 laboratories in 20 countries participated is described. The aim of the study was to define the prevalence of hepatitis B surface antigen (HBsAg), its subtypes, and its antibody (anti-HBs) by age and sex and urban or rural residence in normal populations in different parts of the world. High-risk groups in the populations and patients with various diseases were also investigated. The results of the study confirmed that HBsAg and anti-HBs prevalence rates were higher in African and Asian countries than in the Americas, Australia, and northern and central Europe. Some eastern and southern European countries, however, were also shown to have high HBsAg and anti-HBs prevalence rates, comparable with those in Africa and Asia. In countries with low HBsAg and anti-HBs prevalence, there seems to be a gradual build-up during late childhood or early adolescence, whereas in countries with high HBsAg and its antibody prevalence, they were frequently detected in preschool children. Although the trend was towards a higher frequency of HBsAg and anti-HBs in urban than in rural and in male than in female populations, the differences were in most cases not significant. On the other hand, a significantly higher prevalence of markers of hepatitis B virus infection was seen in high-risk population groups than in normal populations. This was, however, clearly defined only in areas with low HBsAg and anti-HBs prevalence in the normal population. The geographical distribution of HBsAg subtypes showed a higher prevalence of the ad subdeterminant over ay in central European countries, whereas in eastern and southern Europe the ay subtype predominated. In West Africa, ayw was the only variant found, whereas in East Africa ad occurred more frequently than ay. In Australia, both adw and ayw subtypes were detected, whereas in the Far East and South-east Asia only adw and adr were seen. PMID:6969134

    Full Text Available The manuscript presents results from a collaborative study by 15 different laboratories using two different methods to determine tobacco specific nitrosamines (TSNAs in tobacco and was performed under the auspices of the Tobacco Science Research Conference Analytical Methods Committee (TSRC-AMC. Although it is apparent that some of the laboratories failed to follow the provided protocols, both methods proved robust for determining TSNAs in a variety of different tobacco types. Twelve laboratories extracted the tobacco sample using an alkaline-methylene chloride extraction (Method 1 and nine used a buffer to extract the tobacco sample (Method 2. Six laboratories performed both methods. All participants used gas chromatography (GC to separate the TSNAs and chemiluminescence detection. Method 1 used N-hexyl-N-nitroso-1-hexanamine (NDHA as a surrogate (added prior to extraction internal standard for quantitation. Method 2 used N-nitrosoguvacoline (NG as the surrogate internal standard, NDHA as a chromatographic (added after extraction, prior to analysis internal standard and external standard quantitation. After demonstrating that the average accuracy of both methods was at least about 92% through recovery studies, eight different tobacco types were analyzed in triplicate by each method. Means, reproducibility (precision between laboratories and repeatability (precision within a laboratory of results were determined for each method. After statistical analyses, it was established that both methods were capable of analyzing a variety of tobacco types and repeatability between methods was not significantly different. The limit of detection (LOD and limit of quantitation (LOQ were lower for Method 2 as compared to Method 1 when using the surrogate internal standard. Reproducibility variation, analyzed as the coefficient of variation, was 6% lower for Method 2 vs. Method 1 for N-nitrosonornicotine (NNN and directionally 12% lower for 4-(methylnitrosamino

    A collaborative study was conducted to test a method developed to distinguish between adequately and inadequately preserved cosmetic formulations. Nineteen laboratories participated in the study. Samples tested included shampoos, hair conditioners, oil-in-water emulsions, and water-in-oil-emulsions. Triplicate samples of 4 adequately preserved and 4 inadequately preserved cosmetic products were tested by each collaborative laboratory. Results showed that all inadequately preserved shampoo and conditioner samples failed to meet the acceptance criteria for adequately preserved formulations. Of the 51 preserved samples, 49 shampoos and 48 conditioners met the criteria for adequate preservation. All samples of inadequately preserved water-in-oil emulsions and oil-in-water emulsions failed to meet the acceptance criteria, whereas all adequately preserved emulsion formulations met the acceptance criteria.

    Full Text Available Arizona’s Department of Economic Security (DES engaged in a strengths-based initiative to increase quality and integration of human services. Twenty teams including employees from state agencies, community leaders, and families were brought together to discuss and implement improvements to a variety of social services. A mixed methods study was conducted to explore the complex process of forming diverse teams to strengthen social services. Specifically, the research team conducted focus groups to collect qualitative data from a purposive sample of the teams to explore their experiences in greater depth. Analysis of the data led to the development of an online survey instrument that allowed all collaborative members an opportunity to participate in the study. Findings suggest that while the teams faced many challenges, a commitment to the process brought perseverance, communication, and creativity allowing this collaborative to initiate 105 activities to bring about positive changes in social services within their communities.

    A collaborative study was carried out in 30 laboratories to validate improvements to the official final action hydrophobic grid membrane filter (HGMF) screening method for Salmonella in foods, 985.42, by comparing the performance of the improved HGMF method against that of the AOAC/BAM conventional culture method. Six products were included in the collaborative study: milk chocolate, raw deboned poultry meat, black pepper, soy flour, egg yolk powder, and nonfat dry milk. The raw deboned poultry meat was naturally contaminated with Salmonella, and the remaining 5 products were each inoculated in advance with low levels of individual Salmonella serotypes. The AOAC/BAM method produced 11 false negative results and the improved HGMF method produced 18 false negative results. The improved HGMF Salmonella method has been approved interim official first action for all foods to replace the HGMF official final action method, 985.42.

    The research program was collaborative between the researchers at the University of Texas at Dallas and the University of Texas at Austin. The primary subject of this program was to investigate the possibility of active control of secondary electron emission (SEE) from surfaces in contact with plasmas and thereby actively control plasmas. Very few studies of ion-induced electron emission (IIEE) from semiconductors exist, and those that do exist primarily used high-energy ion beams in the experiments. Furthermore, those few studies took extreme measures to ensure that the measurements were performed on atomically clean surfaces because of the surface sensitivity of the IIEE process. Even a small exposure to air can change the IIEE yield significantly. In addition, much of the existing data for IIEE from semiconductors was obtained in the 1950s and ‘60s, when semiconductor materials were first being refined. As a result, nearly all of that data is for p-type Ge and Si. Before this investigation, experimental data on n-type materials was virtually non-existent. While the basic theory assumed that IIEE yields ought to be substantially independent of doping type and concentration, recent measurements of near atmospheric pressure plasmas and of breakdown suggested otherwise. These indirect measurements were made on surfaces that were not atomically clean and seemed to indicate that deep sub-surface changes to the bulk conduction band electron density could lead to substantial variations in the IIEE yield. Exactly in contradiction to the generally accepted theory. Insufficient direct data existed to settle the matter. We performed both experimental measurements and theoretical calculations of IIEE yields from both Si and Ge in order to help clarify whether or not conduction band electrons substantially change the IIEE yield. We used three wafers of each material to carry out the investigation: a heavily doped p-type, an intrinsic and a heavily doped n-type wafer. There

    Full Text Available Abstract Background Physicians have an important but problematic task to issue sickness certifications. A manifold of studies have identified a wide spectrum of medical and insurance-related problems in sickness certification. Despite educational efforts aiming to improve physicians’ knowledge of social insurance medicine there are no signs of reduction of these problems. We hypothesised that the quality deficits is not only due to lack of knowledge among issuing physicians. The aim of the study was to explore physicians’ challenges when handling sickness certification in relation to their professional roles as physicians and to their interaction with different stakeholders. Methods One hundred seventy-seven physicians in Stockholm County, Sweden, participated in a sick-listing audit program. Participants identified challenges in handling sick-leave issues and formulated action plans for improvement. Challenges and responsible stakeholders were identified in the action plans. To deepen the understanding facilitators of the program were interviewed. A qualitative content analysis was performed exploring challenge categories and categories of stakeholders with responsibility to initiate actions to improve the quality of the sick-listing process. The challenge categories were then related by their content to professional competence roles in accord with the Canadian Medical Education Directions for Specialists (CanMEDS framework and to the stakeholder categories. Results Seven categories of challenges were identified. Practitioner patient interaction, Work capacity assessment, Interaction with the Social Insurance Administration, The patient’s workplace and the labour market, Sick-listing practice, Collaboration and resource allocation within the Health Care System, Leadership and routines at the Health Care Unit. The challenges were related to all seven CanMEDS roles. Five categories of stakeholders were identified and several stakeholders

    Currently, many special education policymakers, researchers, and practitioners are questioning the efficacy of pull-out programs for students with disabilities and advocating service delivery in inclusive or general education settings at both the elementary and the secondary level. I investigated the implementation of a collaborative teaching model in a suburban high school to determine how this move toward inclusive education benefited teachers and students. Through examination of the "ups and downs" of a U.S. History teacher, I concluded that replicating and sustaining collaborative teaching can be difficult and complex and, without careful consideration of contextual variables, may not lead to improved outcomes for either teachers or students. Implications for research and practice are discussed.

    Across North America, community agencies and state/provincial jurisdictions are embracing family-centered approaches to service delivery that are grounded in strength-based, culturally responsive, accountable partnerships with families. This article details a collaborative consultation process to initiate and sustain organizational change toward this effort. It draws on innovative ideas from narrative theory, organizational development, and implementation science to highlight a three component approach. This approach includes the use of appreciative inquiry focus groups to elicit existing best practices, the provision of clinical training, and ongoing coaching with practice leaders to build on those better moments and develop concrete practice frameworks, and leadership coaching and organizational consultation to develop organizational structures that institutionalize family-centered practice. While the article uses a principle-based practice framework, Collaborative Helping, to illustrate this process, the approach is applicable with a variety of clinical frameworks grounded in family-centered values and principles.

    In end of the last century information and communication technology caused a veritable evolution in the world of business and commerce. Globalization has changed all the commerce equations and business plans. Old companies have to change their strategies if they want to survive after this technological revolution. A new form of collaboration between the distributed and networked organizations has emerged as the "Virtual Organization" paradigm. A company can not join a virtual organization before obtaining a virtual maturity. This maturity shows the readiness of the company to begin a virtual collaboration. In this paper, based on the coherent and formal definition of virtual organizations, the criteria for measuring the readiness of companies are proposed. Our criteria are confirmed, modified or combined by using the factor analysis method on a sufficient number of virtual companies in the automobile manufacturing industry.

The outcome is a knowledge-based support application tailored to physicians in the local dementia care community. The activity is organized as a part of a collaborative effort between different organizations to develop their local clinical practice. Six local practitioners used the generic decision-support prototype system DMSS-R developed for the dementia domain during a period and participated in evaluations and re-design. Additional two local domain experts and a domain expert external to the local community modeled the content and design of DMSS-R by using the modeling system ACKTUS. Obstacles and success factors occurring when enabling the end-users to design their own tools are detected and interpreted using a proposed framework for improving care through the use of clinical guidelines.

    2014-07-01

    Linking the outcomes from interprofessional education to improvements in patient care has been hampered by educational assessments that primarily measure the short-term benefits of specific curricular interventions. Competencies, recently published by the Interprofessional Education Collaborative (IPEC), elaborate overarching goals for interprofessional education by specifying desired outcomes for graduating health professions students. The competencies define a transition point between the prescribed and structured educational experience of a professional degree program and the more self-directed, patient-oriented learning associated with professional practice. Drawing on the IPEC competencies for validity, we created a 42-item questionnaire to assess outcomes related to collaborative practice at the degree program level. To establish the usability and psychometric properties of the questionnaire, it was administered to all the students on a health science campus at a large urban university in the mid-Atlantic of the United States. The student responses (n = 481) defined four components aligned in part with the four domains of the IPEC competencies. In addition, the results demonstrated differences in scores by domain that can be used to structure future curricula. These findings suggest a questionnaire based on the IPEC competencies might provide a measure to assess programmatic outcomes related to interprofessional education. We discuss directions for future research, such as a comparison of results within and between institutions, and how these results could provide valuable insights about the effect of different curricular approaches to interprofessional education and the success of various educational programs at preparing students for collaborative practice.

    2013-12-01

    A critical part of effective Earth science data and information system interoperability involves collaboration across geographically and temporally distributed communities. The Federation of Earth Science Information Partners (ESIP) is a broad-based, distributed community of science, data and information technology practitioners from across science domains, economic sectors and the data lifecycle. ESIP's open, participatory structure provides a melting pot for coordinating around common areas of interest, experimenting on innovative ideas and capturing and finding best practices and lessons learned from across the network. Since much of ESIP's work is distributed, the Foundation for Earth Science was established as a non-profit home for its supportive collaboration infrastructure. The infrastructure leverages the Internet and recent advances in collaboration web services. ESIP provides neutral space for self-governed groups to emerge around common Earth science data and information issues, ebbing and flowing as the need for them arises. As a group emerges, the Foundation quickly equips the virtual workgroup with a set of ';commodity services'. These services include: web meeting technology (Webex), a wiki and an email listserv. WebEx allows the group to work synchronously, dynamically viewing and discussing shared information in real time. The wiki is the group's primary workspace and over time creates organizational memory. The listserv provides an inclusive way to email the group and archive all messages for future reference. These three services lower the startup barrier for collaboration and enable automatic content preservation to allow for future work. While many of ESIP's consensus-building activities are discussion-based, the Foundation supports an ESIP testbed environment for exploring and evaluating prototype standards, services, protocols, and best practices. After community review of testbed proposals, the Foundation provides small seed funding and a

Results Among 219 participants with non-missing baseline and 12-month data, 24.2% (n=53) reported at least one emergency department visit. Participants with homelessness history (OR=3.76; 95% CI=1.39–10.2; p=.01) or 5 or more care management contacts (OR=2.62; 95% CI=.1.00–6.95; p=.05) had higher probability of emergency department visit, adjusting for demographic and clinical factors including physical health and hospitalization history. Conclusions Individuals with bipolar disorder and history of homelessness were more likely to use the emergency department despite enrollment in a Collaborative Care program, suggesting a greater need for more intensive care coordination.

    Isoflavones are biologically active compounds occurring naturally in a variety of plants, with relatively high levels found in soybeans. Twelve laboratories participated in a collaborative study to determine the aglycon isoflavone content of 8 test samples of soy and foods containing soy. The analytical method for the determination of isoflavones incorporates a mild saponification step that reduces the number of analytes measured and permits quantitation versus commercially available, stable reference standards. Test samples were extracted at 65 degrees C with methanol-water (80 + 20), saponified with dilute sodium hydroxide solution, and analyzed by reversed-phase liquid chromatography with UV detection at 260 nm. Isoflavone results were reported as microg/aglycon/g or microg aglycon equivalents/g. The 8 test samples included 2 blind duplicates and 4 single test samples with total isoflavone concentrations ranging from approximately 50 to 3000 microg/g. Test samples of soy ingredients and products made with soy were distributed to collaborators with appropriate reference standards. Collaborators were asked to analyze test samples in duplicate on 2 separate days. The data were analyzed for individual isoflavone components, subtotals of daidzin-daidzein, glycitin-glycitein, and genistin-genistein, and total isoflavones. The relative standard deviation (RSD) for repeatability was 1.8-7.1%, and the RSD for reproducibility was 3.2-16.1% for total isoflavone values of 47-3099 microg/g.

    We offer a view of the nature and role of client-therapist collaboration in experiential psychotherapy, focusing on Gestalt and emotion-focused therapy (EFT). We distinguish between the necessary condition of mutual trust (the emotional bond between client and therapist) and effective collaboration (regarding the goals and tasks of therapy). Using a case study of experiential therapy for social anxiety, we illustrate how the development of collaboration can be both complex and pivotal for therapeutic success, and how it can involve client and therapist encountering one another through taking risks by openly and nonjudgementally disclosing difficult experiences in order to enrich and advance the work.

    We examine the process through which computational thinking develops in a perspectival fashion as two middle school students collaborate with each other in order to develop computational models of two graphs of motion. We present an interaction analysis of the students' discourse and computational modeling, and analyze how they came to a joint understanding of the goal of the modeling activity. We show that this process involves bringing about coherence between multiple perspectives: the object in motion, the computational agent, the other student, and graphs of motion.

    Aiming to share the information, knowledge and optimizing resource via collaborating with multiple external partners across their supply chains, the concept model and system framework of multi-enterprises collaborative resource planning (MECORP) are put forward. While there is Considerable pressure to improve the operation of MECORP system, their inherent complexity can make modelling a MECORP system a difficult task. Yet there could be considerable benefits in designing MECORP taking into account the operation of the system. In order to address the central research issue of developing of a methodology that can assist a manager in making decisions by modelling the operation of MECORP system. The methodology called process-oriented decision model (PODM) is presented in the paper. This uses an abstracted network to model MECORP system. The MECORP system supported by PODM, can effective optimize the manifold resource, coordinate the relationship of multiple partners and assist decision. Finally, an industry example of MECORP system is described to illustrate the application of PODM.

    Objective: To incorporate students and other local community partners in creating a collaborative Nanjing World AIDS Day exhibition. Background: Stigma and discrimination continue to complicate effective World AIDS Day activities in China. Including foreign students in World AIDS Day campaigns broadens the potential Chinese audience as well as making the government's AIDS policiesmore transparent. Methods: In order to broaden the potential audience, relevant media (television, radio, newspaper) were notified of the 2003 Nanjing World AIDS Day Exhibition. The exhibition represented a unique collaboration between Nanjing University and the Chinese National Center for STD and Leprosy Control, depending on foreign and Chinese students at several levels. In addition, close contacts at the Jiangsu Provincial Health Bureau helped to coordinate local experts and distribution of condoms. Results: This multi-disciplinary cooperative exhibition was successfully completed. Several major media sources covered the event. Conclusions: The success of this campaign suggests that other urban cities with significant foreign student populations could benefit from including foreign and Chinese students in future World AIDS Day campaign activities.

    Current engineering pedagogy primarily focuses on developing technical proficiency and problem solving skills; the peer-review process for sharing new research results is often overlooked. The use of a collaborative classroom journal club can engage students with the excitement of scientific discovery and the process of dissemination of research results, which are also important lifelong learning skills. In this work, a classroom journal club was implemented and a survey of student perceptions spanning three student cohorts was collected. In this collaborative learning activity, students regularly chose and discussed a recent biomechanics journal article, and were assessed based on specific, individual preparation tasks. Most student-chosen journal articles were relevant to topics discussed in the regular class lecture. Surveys assessed student perceptions of the activity. The survey responses show that, across all cohorts, students both enjoyed the classroom journal club and recognized it as an important learning experience. Many reported discussing their journal articles with others outside of the classroom, indicating good engagement. The results demonstrate that student engagement with primary literature can foster both technical knowledge and lifelong learning skills.

    Full Text Available Though separated by geographical distance, a student with disabilities, his advisor, and his writing coach consorted in the Cloud using Google applications to achieve a writing goal. Our scenario demonstrates how emerging technologies can bridge transactional distance and “virtually” supplant face-to-face conferencing around a college writing assignment. Individual levels of technical acumen with digital technology evolved to bridge the psychological and communication space between the student and his instructors. As a result, the telecollaborators developed an efficient coaching process adaptable for all students who need assistance in revising college writing assignments at a distance. Action research frames our discussion of the Cloud collaboration and provides a scaffold for student autonomy. The advantages as well and disadvantages of Cloud collaboration are outlined with reference to the National Institute of Standards of Technology definition of Cloud Computing and the Seven Principles of Universal Course Design.http://dx.doi.org/10.5944/openpraxis.6.1.79

    Plant-herbivore interactions are central to the functioning of tundra ecosystems, but their outcomes vary over space and time. Accurate forecasting of ecosystem responses to ongoing environmental changes requires a better understanding of the processes responsible for this heterogeneity. To effectively address this complexity at a global scale, coordinated research efforts, including multi-site comparisons within and across disciplines, are needed. The Herbivory Network was established as a forum for researchers from Arctic and alpine regions to collaboratively investigate the multifunctional role of herbivores in these changing ecosystems. One of the priorities is to integrate sites, methodologies, and metrics used in previous work, to develop a set of common protocols and design long-term geographically-balanced, coordinated experiments. The implementation of these collaborative research efforts will also improve our understanding of traditional human-managed systems that encompass significant portions of the sub-Arctic and alpine areas worldwide. A deeper understanding of the role of herbivory in these systems under ongoing environmental changes will guide appropriate adaptive strategies to preserve their natural values and related ecosystem services.

    Full Text Available Abstract Background Cardiovascular disease (CVD is the main cause of death in patients on chronic dialysis. The question whether dialysis modality impacts cardiovascular risk remains to be addressed. China Collaborative Study on Dialysis, a multi-centers cohort study, was performed to evaluate cardiovascular morbidity during maintenance hemodialysis (HD and peritoneal dialysis (PD. Method The cohort consisted of chronic dialysis patients from the database of 9 of the largest dialysis facilities around China. The inclusion period was between January 1, 2005, and December 1, 2010. Cardiovascular morbidity was defined as the presence of clinically diagnosed ischemic heart disease, heart failure, peripheral vascular disease, and/or stroke. The patients who had cardiovascular morbidity before initiation of dialysis were excluded. Data collection was based on review of medical record. Result A total of 2,388 adult patients (1,775 on HD and 613 on PD were enrolled. Cardiovascular morbidity affected 57% patients and was comparable between HD and PD patients. However, clinically diagnosed ischemic heart disease and stroke was more prevalent in PD than HD patients. When the patients were stratified by age or dialysis vintage, the cardiovascular morbidity was significantly higher in PD than HD among those aged 50 years or older, or those receiving dialysis over 36 months. Multivariate analysis revealed that the risk factors for cardiovascular morbidity had different pattern in PD and HD patients. Hyperglycemia was the strongest risk factor for cardiovascular morbidity in PD, but not in HD patients. Hypertriglyceridemia and hypoalbuminemia were independently associated with CVD only in PD patients. Conclusions Cardiovascular morbidity during chronic dialysis was more prevalent in PD than HD patients among those with old age and long-term dialysis. Metabolic disturbance-related risk factors were independently associated with CVD only in PD patients

    Full Text Available Abstract Background Ongoing care for chronic conditions such as diabetes is best provided by a range of health professionals working together. There are challenges in achieving this where collaboration crosses organisational and sector boundaries. The aim of this article is to explore the influence of power dynamics and trust on collaboration between health professionals involved in the management of diabetes and their impact on patient experiences. Methods A qualitative case study conducted in a rural city in Australia. Forty five health service providers from nineteen organisations (including fee-for-service practices and block funded public sector services and eight patients from two services were purposively recruited. Data was collected through semi-structured interviews that were audio-taped and transcribed. A thematic analysis approach was used using a two-level coding scheme and cross-case comparisons. Results Three themes emerged in relation to power dynamics between health professionals: their use of power to protect their autonomy, power dynamics between private and public sector providers, and reducing their dependency on other health professionals to maintain their power. Despite the intention of government policies to support more shared decision-making, there is little evidence that this is happening. The major trust themes related to role perceptions, demonstrated competence, and the importance of good communication for the development of trust over time. The interaction between trust and role perceptions went beyond understanding each other's roles and professional identity. The level of trust related to the acceptance of each other's roles. The delivery of primary and community-based health services that crosses organisational boundaries adds a layer of complexity to interprofessional relationships. The roles of and role boundaries between and within professional groups and services are changing. The uncertainty and

    Tourette syndrome (TS) is a neuropsychiatric disorder characterized by recurrent motor and vocal tics, often accompanied by obsessive-compulsive disorder and/or attention-deficit/hyperactivity disorder. While the evidence for a genetic contribution is strong, its exact nature has yet to be clarified fully. There is now mounting evidence that the genetic risks for TS include both common and rare variants and may involve complex multigenic inheritance or, in rare cases, a single major gene. Based on recent progress in many other common disorders with apparently similar genetic architectures, it is clear that large patient cohorts and open-access repositories will be essential to further advance the field. To that end, the large multicenter Tourette International Collaborative Genetics (TIC Genetics) study was established. The goal of the TIC Genetics study is to undertake a comprehensive gene discovery effort, focusing both on familial genetic variants with large effects within multiply affected pedigrees and on de novo mutations ascertained through the analysis of apparently simplex parent-child trios with non-familial tics. The clinical data and biomaterials (DNA, transformed cell lines, RNA) are part of a sharing repository located within the National Institute for Mental Health Center for Collaborative Genomics Research on Mental Disorders, USA, and will be made available to the broad scientific community. This resource will ultimately facilitate better understanding of the pathophysiology of TS and related disorders and the development of novel therapies. Here, we describe the objectives and methods of the TIC Genetics study as a reference for future studies from our group and to facilitate collaboration between genetics consortia in the field of TS.

    Full Text Available A substantial challenge facing multicentre audit and research projects is timely recruitment of collaborators and their study centres. Cost-effective strategies are required and fee-free social media has previously been identified as a potential conduit. We investigated and evaluated the effectiveness of a novel multi-format social media and Internet strategy for targeted recruitment to a national multicentre cohort study.Interventions involved a new Twitter account, including weekly live question-and-answer sessions, a new Facebook group page, online YouTube presentations and an information page on a national association website. Link tracking analysis was undertaken using Google Analytics, which was then related to subsequent registration. Social influence was calculated using the proprietary Klout score.Internet traffic analysis identified a total of 1562 unique registration site views, of which 285 originated from social media (18.2%. Some 528 unique registrations were received, with 96 via social media platforms (18.2%. Traffic source analysis identified a separate national association webpage as resulting in the majority of registration page views (15.8%, followed by Facebook (11.9%, Twitter (4.8% and YouTube (1.5%. A combination of publicity through Facebook, Twitter and the dedicated national association webpage contributed to the greatest rise in registration traffic and accounted for 312 (48% of the total registrations within a 2-week period. A Twitter 'social influence' (Klout score of 42/100 was obtained during this period.Targeted social media substantially aided study dissemination and collaborator recruitment. It acted as an adjunct to traditional methods, accounting for 18.2% of collaborator registration in a short time period with no associated financial costs. We provide a practical model for designing future recruitment campaigns, and recommend Facebook, Twitter and targeted websites as the most effective adjuncts for

    The Advancing Geospatial Skills in Science and Social Sciences (AGSSS) program, funded by NSF, provides middle and high school teacher-partners with access to graduate student scientists for classroom collaboration and curriculum adaptation to incorporate and advance skills in spatial thinking. AGSSS Fellows aid in the delivery of geospatially-enhanced activities utilizing technology such as geographic information systems, remote sensing, and virtual globes. The partnership also provides advanced professional development for both participating teachers and fellows. The AGSSS program is mutually beneficial to all parties involved. This successful collaboration of scientists, teachers, and students results in greater understanding and enthusiasm for the use of spatial thinking strategies and geospatial technologies. In addition, the partnership produces measurable improvements in student efficacy and attitudes toward processes of spatial thinking. The teacher partner training and classroom resources provided by AGSSS will continue the integration of geospatial activities into the curriculum after the project concludes. Time and resources are the main costs in implementing this partnership. Graduate fellows invest considerable time and energy, outside of academic responsibilities, to develop materials for the classroom. Fellows are required to be available during K-12 school hours, which necessitates forethought in scheduling other graduate duties. However, the benefits far outweigh the costs. Graduate fellows gain experience in working in classrooms. In exchange, students gain exposure to working scientists and their research. This affords graduate fellows the opportunity to hone their communication skills, and specifically allows them to address the issue of translating technical information for a novice audience. Teacher-partners and students benefit by having scientific expertise readily available. In summation, these experiences result in changes in teacher

  8. Gender differences in an elementary school learning environment: A study on how girls learn science in collaborative learning groups

    Science.gov (United States)

    Greenspan, Yvette Frank

    Girls are marked by low self-confidence manifested through gender discrimination during the early years of socialization and culturalization (AAUW, 1998). The nature of gender bias affects all girls in their studies of science and mathematics, particularly in minority groups, during their school years. It has been found that girls generally do not aspire in either mathematical or science-oriented careers because of such issues as overt and subtle stereotyping, inadequate confidence in ability, and discouragement in scientific competence. Grounded on constructivism, a theoretical framework, this inquiry employs fourth generation evaluation, a twelve-step evaluative process (Guba & Lincoln, 1989). The focus is to discover through qualitative research how fifth grade girls learn science in a co-sexual collaborative learning group, as they engage in hands-on, minds-on experiments. The emphasis is centered on one Hispanic girl in an effort to understand her beliefs, attitudes, and behavior as she becomes a stakeholder with other members of her six person collaborative learning group. The intent is to determine if cultural and social factors impact the learning of scientific concepts based on observations from videotapes, interviews, and student opinion questionnaires. QSR NUD*IST 4, a computer software program is utilized to help categorize and index data. Among the findings, there is evidence that clearly indicates girls' attitudes toward science are altered as they interact with other girls and boys in a collaborative learning group. Observations also indicate that cultural and social factors affect girls' performance as they explore and discover scientific concepts with other girls and boys. Based upon what I have uncovered utilizing qualitative research and confirmed according to current literature, there seems to be an appreciable impact on the way girls appear to learn science. Rooted in the data, the results mirror the conclusions of previous studies, which

    This study focus on the knowledge aspect of inter-organizational technology transfer projects. We have studied two large R&D collaborations where CERN is involved as one of several participating organizations, in order to reveal the causalities related to the knowledge transfer processes within these projects. The objective of the study is to understand how knowledge transfer happens, identify influencing factors to the process, and finally investigate the outcome of such processes. The study is founded on a thorough literature review where we examine different aspects of inter-organizational knowledge transfer. Based on the theory, we develop an analytic framework and establish different elements in the knowledge transfer process to study in more detail. This framework illustrates the relation between the different elements in a knowledge transfer process and provides the structure for our empirical foundation. We perform an explanatory embedded multiple case study and analyze our findings in terms of th...

This paper identifies the potential of school nursing to provide the vision and multiagency leadership required to coordinate multidisciplinary collaboration.Method: A mixed-method single-case study design using Yin's approach, including focus groups, interviews, and analysis of policy documents and public health reports.Results: A model that explains the integrated population approach to managing school-age asthma is described; the role of the lead school nurse coordinator was seen as critical to the development and sustainability of the model.Conclusion: School nurses can provide strategic multidisciplinary leadership to address pressing public health issues. Health service managers and commissioners need to understand how to support clinicians working across multiagency boundaries and to identify how to develop leadership skills for collaborative interprofessional practice so that the capacity for nursing and other health care professionals to address public health issues does not rely on individual motivation. In England, this will be of particular importance to the commissioning of public health services by local authorities from

Two instruments, the Collaboration and Satisfaction About Care Decisions Scale and the University of the West of England Interprofessional Questionnaire (comprised of 4 subscales-Communication and Teamwork Scale, Interprofessional Learning Scale, Interprofessional Interaction Scale, and Interprofessional Relationships Scale were administered to providers at baseline and three to eight months following six same discipline focus group discussions on collaboration, in order to evaluate whether participating in the focus group discussions changed providers' views of collaboration. A summary of the focus group data which were published elsewhere is additionally summarized to help provide insight to the quantitative findings. Thirty-nine staff participated.Results: Paired t-tests revealed that only one scale out of the five, Collaboration and Satisfaction About Care Decisions Scale (33.97 at time one and 37.45 at time two, significantly and positively changed after the focus group discussion (p=0.046. Providers' views on collaboration ranged from positive to moderate views of collaboration; most measures revealed a non-significant improvement after the focus group discussions. Staff with some graduate school reported the greatest

    Patient safety research has to date offered few opportunities for patients and families to be actively involved in the research process. This article describes our collaboration with patients and families in two separate studies, involving end-of-life care and infection control in acute care. We used the collaborative methodology of video-reflexive ethnography, which has been primarily used with clinicians, to involve patients and families as active participants and collaborators in our research. The purpose of this article is to share our experiences and findings that iterative researcher reflexivity in the field was critical to the progress and success of each study. We present and analyze the complexities of reflexivity-in-the-field through a framework of multilayered reflexivity. We share our lessons here for other researchers seeking to actively involve patients and families in patient safety research using collaborative visual methods.

    Full Text Available This paper has identified a research gap to study how organizations collaborate together to adopt Inter- Organizational System (IOS for Supply Chain Management (SCM. We propose such a framework and then use four theories, namely resource dependency theory, organizational theory, actor-network theory and negotiated order theory, to understand how the framework supports management collaboration and interaction in the adoption of an IOS. This adoption framework is proposed to better study how senior management staff, from both supplier and customer perspectives, collaborate and interact in the IOS adoption process. The framework has been constructed from the literature identifying six major aspects for consideration namely: inter and intra organizational collaboration; strategic management approaches; supply chain design (SCD; business process redesign/reengineering (BPR; information systems (IS / information technology (IT architecture and external environmental factors. From customer and supplier perspectives the adoption of IOS for SCM, makes a significant contribution to knowledge in this field.

    Full Text Available Purpose: This paper is an attempt to investigate the current issues and development of the supply chain collaborative technological innovation in China. Design/methodology/approach: DEA is employed to measure the efficiency of the supply chain collaborative technological innovation. Findings: From the results of this research, we can get the conclusion that there are big spaces for improvement for the selected companies in terms of supply chain collaborative technological innovation, especially in the collaborative benefit aspect. The efficiencies of the supply chain collaborative technological innovation in the selected companies vary a lot. Research limitations: More industries are needed to generalize the conclusions. Practical implications: Our practical recommendations for improving supply chain companies in terms of improving their collaborative technological innovation efficiency are: (1 expanding the cooperative scope; (2 optimizing the collaboration operations; (3 improving the compactness in supply chain; (4 increasing the innovation input; and (5 improving the knowledge exchange capacity. Originality/value: The evaluation and the measure of the efficiency of performance of the collaborative technological innovation both in theory and in practice have been proven to be very important and quite complex, and there have been limited researches in the current literature. From observations, however, the efficiency of supply chain collaborative technological innovation is relatively low. This research investigates the current issues and development of the supply chain collaborative technological innovation in China, and provides the guideline in terms of improving the efficiency of supply chain collaborative technological innovation.

    The outbreak of human infections of a novel avian influenza virus A (H7N9) prompted the development of the vaccines against this virus. Like all types of influenza vaccines, H7N9 vaccine must be tested for its potency prior to being used in humans. However, the unavailability of international reference reagents for the potency determination of H7N9 vaccines substantially hinders the progress in vaccine development. To facilitate clinical development, we enlisted 5 participants in a collaborative study to develop critical reagents used in Single Radial Immunodiffusion (SRID), the currently acceptable assay for potency determination of influenza vaccine. Specifically, the hemagglutinin (HA) content of one vaccine bulk for influenza A (H7N9), herein designated as Primary Liquid Standard (PLS), was determined by SDS-PAGE. In addition, the freeze-dried antigen references derived from PLS were prepared to enhance the stability for long term storage. The final HA content of lyophilized antigen references were calibrated against PLS by SRID assay in a collaborative study. Importantly, application of these national reference standards to potency analyses greatly facilitated the development of H7N9 vaccines in China. PMID:25970793

    A collaborative study was conducted to determine the protein content of raw and processed meat products by a protein-tagging and colorimetric technique. Meat products were prepared following AOAC Official Method 983.18 and analyzed using CEM Corporation's Sprint Rapid Protein Analyzer. Sprint provides protein results by combining an accurately weighed test portion with a known amount of dye-binding agent. The dye-binding agent binds with the lysine, histidine, and arginine, as well as the n-terminus of the proteins commonly found in raw meat and processed meat products. Results are displayed and reported by the Sprint as a percentage (g/100 g) of protein. Ten blind duplicate study samples were sent to 10 collaborating laboratories in the United States. The within-laboratory (repeatability) relative standard deviation (RSD(r)) ranged from 0.91 to 3.04%, and between-laboratories (reproducibility) relative standard deviation (RSDR) ranged from 1.50 to 3.41% for protein. The method is recommended for Official First Action.

    The purpose of this document is to provide an overview of a collaboration science process used to develop recommendations for the field of telemental health (TMH) in the selection of outcome measures that best reflect programmatic impacts. A common use of group development techniques in medicine is the development of clinical guidelines, which typically occurs using one of two methods: the nominal group or the Delphi method. Both processes have been faulted for limited transparency, reliability, and sustainability. Recommendations to improve the traditional process include making goals explicit, making disagreements transparent, and publicly displaying levels of agreement. A group of 26 TMH experts convened during the American Telemedicine Association's 2012 Fall Forum in New Orleans, LA to participate in a 1-day, interactive, consensus-building workshop to initiate the development of a shared lexicon of outcomes. The workshop method was designed to improve on traditional methods of guideline development by focusing on clarity of expectations, transparency, and timeliness of group development work. Results suggest that, compared with other traditional methods, the current process involved more people, occurred more rapidly, was more transparent, and resulted in a comparable deliverable. Recommendations for further process development, both within and external to TMH, as well as an initial overview of defined outcome measures are discussed.

    The trend in cognitive rehabilitation toward reduced services, which provide more functionally relevant outcomes and the recognition of limited maintenance and generalization with many existing interventions, challenges current research models. There is a need to develop and evaluate interventions that can be implemented by persons other than rehabilitation professionals and that are well suited to naturalistic settings. The researchers responded to these challenges by designing a series of single subject experiments evaluating the effectiveness of training caregivers to provide appropriate cognitive support to persons with brain injury within their own natural living environments. The goal of the original research project included evaluating a collaborative mode of interaction with the subjects and their support persons (as opposed to traditional directive treatment models) where the caregivers and subjects were instrumental in designing the intervention and collective performance data. This paper presents the data from the initial three subject/caregiver groups all of whom demonstrated improvement in the target behaviours during the baseline period. It appeared that the act of measuring client performance changed the behaviours of the support persons and resulted in positive changes in baseline levels. The research and clinical implications of these findings are discussed.

    This study aims to explore the impact of physician-nurse collaboration on nurse job satisfaction and turnover in a dental hospital. Physician-nurse collaboration is important for the stability of the entire nursing team. Few studies have shown the impact on job satisfaction and turnover among nurses working in Chinese dental hospitals. This was a prospective, cross-sectional study and investigated nurses from a tertiary dental hospital in Beijing using convenience non-randomized sampling. A structured questionnaire was used to collect data, which included general information, the Index of Work Satisfaction, the Nurse-Physician Collaboration Scale and the Turnover Intention Scale. The scores of physician-nurse collaboration correlated positively with those for job satisfaction and negatively with the stated likelihood of turnover intention. Physician-nurse collaboration scores positively predicted job satisfaction and negatively predicted the likelihood of quitting the current job. In conclusion, improving the level of physician-nurse collaboration is helpful to enhance job satisfaction and reduce turnover among nurses in a dental hospital.

    This interpretive case study describes a collaborative project involving a physics professor and a science educator. We report what was learned about factors that influenced the professor's development of teaching strategies, alternative to lecture, that were intended to promote prospective teachers' meaningful learning and their use of canonical ways of communicating physics concepts. We describe how the professor's beliefs influenced the pedagogy that he used to communicate the language of physics and the nature of what was communicated. We also report how our collaboration fostered change as we developed a shared language that allowed us to discuss how students learn and to explicate the referent beliefs that supported the professor's practices. We found that focused reflection on referent beliefs led to a change in the manner in which the professor communicated with the prospective teachers. Traditional lecture pedagogy focused the professor's concern on how he was teaching evolved toward a pedagogy that focused on how students were learning. Classroom interactions were increased with a primary goal of orchestrating a discourse of physics initiated in the language already accessible to the prospective teachers. This change in the manner that classroom interactions occurred provided opportunities for the prospective teachers' language to evolve toward eventually communicating their ideas in canonical physics language.

    Until recently, governmental organizations played a dominant and decisive role in natural resource management. However, an increasing number of studies indicate that this dominant role is developing towards a more facilitating role as equal partner to improve efficiency and create a leaner state. This approach is characterized by complex collaborative relationships between various actors and sectors on multiple levels. To understand this complexity in the field of environmental management, we conducted a social network analysis of floodplain management in the Dutch Rhine delta. We charted the current interorganizational relationships between 43 organizations involved in flood protection (blue network) and nature management (green network) and explored the consequences of abolishing the central actor in these networks. The discontinuation of this actor will decrease the connectedness of actors within the blue and green network and may therefore have a large impact on the exchange of ideas and decision-making processes. Furthermore, our research shows the dependence of non-governmental actors on the main governmental organizations. It seems that the Dutch governmental organizations still have a dominant and controlling role in floodplain management. This challenges the alleged shift from a dominant government towards collaborative governance and calls for detailed analysis of actual governance.

  9. Benefits of multidisciplinary collaboration for earthquake casualty estimation models: recent case studies

    Science.gov (United States)

    So, E.

    2010-12-01

    Earthquake casualty loss estimation, which depends primarily on building-specific casualty rates, has long suffered from a lack of cross-disciplinary collaboration in post-earthquake data gathering. An increase in our understanding of what contributes to casualties in earthquakes involve coordinated data-gathering efforts amongst disciplines; these are essential for improved global casualty estimation models. It is evident from examining past casualty loss models and reviewing field data collected from recent events, that generalized casualty rates cannot be applied globally for different building types, even within individual countries. For a particular structure type, regional and topographic building design effects, combined with variable material and workmanship quality all contribute to this multi-variant outcome. In addition, social factors affect building-specific casualty rates, including social status and education levels, and human behaviors in general, in that they modify egress and survivability rates. Without considering complex physical pathways, loss models purely based on historic casualty data, or even worse, rates derived from other countries, will be of very limited value. What’s more, as the world’s population, housing stock, and living and cultural environments change, methods of loss modeling must accommodate these variables, especially when considering casualties. To truly take advantage of observed earthquake losses, not only do damage surveys need better coordination of international and national reconnaissance teams, but these teams must integrate difference areas of expertise including engineering, public health and medicine. Research is needed to find methods to achieve consistent and practical ways of collecting and modeling casualties in earthquakes. International collaboration will also be necessary to transfer such expertise and resources to the communities in the cities which most need it. Coupling the theories and findings from

    In this paper, we use bibliometric methods and social network analysis to analyze the pattern of China-US scientific collaboration on individual level in nanotechnology. Results show that Chinese-American scientists have been playing an important role in China-US scientific collaboration. We find that China-US collaboration in nanotechnology mainly occurs between Chinese and Chinese-American scientists. In the co-authorship network, Chinese-American scientists tend to have higher betweenness centrality. Moreover, the series of polices implemented by the Chinese government to recruit oversea experts seems to contribute a lot to China-US scientific collaboration.

    The Multi-Site University Study of Identity and Culture (MUSIC) is the product of a research collaboration among faculty members from 30 colleges and universities from across the United States. Using Katz and Martin's (1997, p. 7) definition, the MUSIC research collaboration is "the working together of researchers to achieve the common goals of producing new scientific knowledge." The collaboration involved more than just coauthorship; it served "as a strategy to insert more energy, optimism, creativity and hope into the work of [researchers]" (Conoley & Conoley, 2010, p. 77). The philosophy underlying the MUSIC collaborative was intended to foster natural collaborations among researchers, to provide opportunities for scholarship and mentorship for early career and established researchers, and to support exploration of identity, cultural, and ethnic/racial research ideas by tapping the expertise and interests of the broad MUSIC network of collaborators. In this issue, five research articles present innovative findings from the MUSIC datasets. There are two themes across the articles. Research is emerging about broadening the constructs and measures of acculturation and ethnic identity and their relation to health risk behaviors and psychosocial and mental health outcomes. The second theme is about the relationship of perceived discrimination on behavioral and mental health outcomes among immigrant populations.

    Collaboration is a critical competency for modern organizations as they struggle to compete in an increasingly complex, global environment. A large body of research on collaboration in the workplace focuses both on teams, investigating how groups use teamwork to perform their task work, and on the use of information systems to support team processes ("collaboration engineering"). This research essay presents collaboration from an engineering perspective ("collaborative engineering"). It uses examples from professional and student engineering teams to illustrate key differences in collaborative versus collaboration engineering and investigates how challenges in the former can inform opportunities for the latter.

    Full Text Available UK public policy makers have a growing interest in collaborative research, where academics work with public, private or third sector partners on a joint project which supports the partner’s aims. This paper reports on the findings of five case studies, looking at how information is sourced, managed, used and shared within collaborative research projects. It finds that researchers within collaborative projects have similar information management issues as are known to exist within academia more broadly, but that the specific conditions which govern research collaborations mean that interventions to improve or support information management must be carefully tailored.

    This study provides empirical data about shipboard practices in bridge operations on board a selection of platform supply vessels (PSVs). Using the theoretical concept of distributed situation awareness, the study examines how situation awareness (SA)-related information is distributed and coordinated at the bridge. This study thus favours a systems approach to studying SA, viewing it not as a phenomenon that solely happens in each individual's mind but rather as something that happens between individuals and the tools that they use in a collaborative system. Thus, this study adds to our understanding of SA as a distributed phenomenon. Data were collected in four field studies that lasted between 8 and 14 days on PSVs that operate on the Norwegian continental shelf and UK continental shelf. The study revealed pronounced variations in shipboard practices regarding how the bridge team attended to operational planning, communication procedures, and distracting/interrupting factors during operations. These findings shed new light on how SA might decrease in bridge teams during platform supply operations. The findings from this study emphasize the need to assess and establish shipboard practices that support the bridge teams' SA needs in day-to-day operations.

    As healthcare delivery becomes increasingly interprofessional, it is imperative to identify opportunities for effective collaboration and coordination of care. Drawing on a Canadian qualitative study that adopted a constant comparative method based on the grounded theory approach, we report how healthcare providers' (HCPs) personal experiences and professional roles intersect with system factors in hindering or enhancing their ability to support patients and families in planning for end-of-life (EOL) care. We used a criterion-based sampling strategy and sought HCPs who had direct experience engaging patients and families in complex healthcare decisions on: (1) initiating, withholding, or withdrawing treatment; (2) care planning; and/or (3) discharge planning. Interviews sought to understand what HCPs perceived as individual, (inter)professional, and system factors that might hinder, promote, or enhance support for patients/families. We present four major intersecting themes from in-depth interviews with 28 HCPs across acute, long-term, and community care settings that represent three barriers and one facilitator: discomfort with death and dying, confusion about role responsibility, lack of coordinated care, and importance of interprofessional teamwork. Attending to system power hierarchy, we explore interprofessional strategies to support patients' and families' care experiences and promote team-based decision-making. We recommend an interprofessional team approach to facilitate EOL decision-making across care settings and before death becomes imminent. Increasing educational initiatives and developing tools that focus on interprofessional collaboration may help HCPs to understand each other's roles and perspectives, so that they can work together to provide a more coherent and coordinated approach to EOL decision-making.

    Colorectal cancer is the third most common cancer worldwide, and many risk factors for colorectal cancer have been established. However, it remains uncertain whether psychological stress contributes to the onset of colorectal cancer. Therefore, we conducted a large-scale prospective cohort study to confirm the association between perceived stress and colorectal cancer incidence. We identified 680 cases of colon cancer and 330 cases of rectal cancer during a maximum of 21-year follow-up of 61,563 Japanese men and women. Cox regression analysis adjusted for potential confounders revealed a significant association of perceived stress with rectal cancer incidence but not with colon cancer incidence. This finding is partly consistent with that from only one previous study that addressed an association between perceived stress and the risk of colorectal cancer. However, studies on this topic are sparse and warrant further exploration. PMID:28091607

    Clinical ethic situations in modern multiprofessional healthcare systems may involve different healthcare professions who work together for patient care. The undergraduate interprofessional education of clinical ethics would help to incubate healthcare students' ability of interprofessional collaboration in solving ethical problems. However, the impact from an interprofessional educational model on student's attitudes and confidence of interprofessional collaboration should be carefully evaluated during the process of curricular development. This study aimed to conduct a pilot interprofessional PBL curriculum of clinical ethics and evaluate the curricular impact on interprofessional students' attitude and confidence of collaborative teamwork. Thirty-six medical and nursing students volunteered to participate in this study and were divided into three groups (medical group, nursing group, and mixed group). Tutors were recruited from the Medical School and the College of Nursing. The pilot curriculum included one lecture of clinical ethics, one PBL case study with two tutorial sessions, and one session of group discussion and feedback. A narrative story with multiple story lines and a multiperspective problem analysis tool were used in the PBL tutorials. The students' self-evaluation of learning questionnaire was used to evaluate students' learning of clinical ethics and interprofessional collaborative skills and attitude. The internal consistency of the questionnaire was measured by Cronbach α, and the criterion-related validity of the questionnaire was evaluated through associations between the dimension scores with the student group by one-way analysis of variance test (ANOVA) test and Tukey-Kramer honestly significant difference (HSD) comparison. There was significant difference among different groups in students' ability and attitudes about "interprofessional communication and collaboration" (p = 0.0184). The scores in the mixed group (37.58 ± 3.26) were higher

    The proposed study will investigate the effect of active electron injection of from electrode surfaces To the best of our knowledge, no such a study has ever been attempted even though it could lead to the formation of whole new classes of plasma based devices and systems. We are motivated by recent articles and simple theory which gives strong reason to believe that embedded electronic devices can be used to exert control over the SEE coefficient of semiconductor surfaces (and maybe other surface types as well). Furthermore, the research will explore how such sub-surface electronic devices can best be used to exert control over an associated plasma.

    The objective of this collaborative study was to determine interlaboratory performance statistics for a modified and optimized version of AOAC Method 920.123 for the determination of the total nitrogen content of hard, semihard, and processed cheese by Kjeldahl analysis. Details included addressing the issues of material homogeneity, test portion size (1 g), quantitative transfer (weighing on to filter paper), ensuring system suitability (nitrogen recoveries), and using AOAC Method 991.20 as the basis for nitrogen analysis. Fifteen laboratories tested 18 pairs of blind duplicate cheese materials with a crude protein content between 18 and 36%. Materials represented hard, semihard, and processed commercial cheeses with a wide range of composition. Statistical performance parameters expressed as crude protein (nitrogen x 6.38), g/100 g, with invalid and outlier data removed were mean = 26.461, repeatability standard deviation (Sr) 0.111, reproducibility standard deviation (S(R)) = 0.153, repeatability relative standard deviation (RSDr) = 0.42%, reproducibility relative standard deviation (RSDR) = 0.58%, repeatability (r) = 0.312, and reproducibility (R) = 0.428. The interlaboratory study results were acceptable and comparable to those for the milk Kjeldahl nitrogen method on a relative nitrogen basis. The Study Directors recommend that this modified method for the determination of total nitrogen in hard, semihard, and processed cheese by Kjeldahl analysis be adopted First Action as an improved method to replace Method 920.123.

    Full Text Available Abstract Background Individuals born small for gestational age (SGA are at increased risk of rapid postnatal weight gain, later obesity and diseases in adulthood such as type 2 diabetes, hypertension and cardiovascular diseases. Environmental risk factors for SGA are well established and include smoking, low pregnancy weight, maternal short stature, maternal diet, ethnic origin of mother and hypertension. However, in a large proportion of SGA, no underlying cause is evident, and these individuals may have a larger genetic contribution. Methods In this study we tested the association between SGA and polymorphisms in genes that have previously been associated with obesity and/or diabetes. We undertook analysis of 54 single nucleotide polymorphisms (SNPs in 546 samples from the Auckland Birthweight Collaborative (ABC study. 227 children were born small for gestational age (SGA and 319 were appropriate for gestational age (AGA. Results and Conclusion The results demonstrated that genetic variation in KCNJ11, BDNF, PFKP, PTER and SEC16B were associated with SGA and support the concept that genetic factors associated with obesity and/or type 2 diabetes are more prevalent in those born SGA compared to those born AGA. We have previously determined that environmental factors are associated with differences in birthweight in the ABC study and now we have demonstrated a significant genetic contribution, suggesting that the interaction between genetics and the environment are important.

  19. Improved results in paediatric diabetes care using a quality registry in an improvement collaborative: a case study in Sweden.

    Directory of Open Access Journals (Sweden)

    Anette Peterson

    Full Text Available Several studies show that good metabolic control is important for children and adolescents with type 1 diabetes. In Sweden, there are large differences in mean haemoglobin A1c (HbA1c in different hospitals and difficulties implementing national guidelines in everyday practice. This study shows how the participation in an improvement collaborative could facilitate improvements in the quality of care by paediatric diabetes teams. The Swedish paediatric diabetes quality registry, SWEDIABKIDS was used as a tool and resource for feedback and outcome measures.Twelve teams at paediatric diabetes centres, caring for 30% (2302/7660 of patients in Sweden, participated in an 18-month quality improvement program. Each team defined treatment targets, areas needing improvement, and action plans. The main outcome was the centre patients' mean HbA1c levels, but other clinical variables and change concepts were also studied. Data from the previous six months were compared with the first six months after starting the program, and the long-term follow up after another eleven months.All centres reduced mean HbA1c during the second and third periods compared with the first. The mean reduction for all was 3·7 mmol/mol (p<0.001, compared with non-participating centres who improved their mean HbA1c with 1·7 mmol/mol during the same period. Many of the participating centres reduced the frequency of severe hypoglycaemia and/or ketoacidosis, and five centres reached their goal of ensuring that all patients had some sort of physical activity at least once weekly. Change concepts were, for example, improved guidelines, appointment planning, informing the patients, improving teamwork and active use of the registry, and health promotion activities.By involving paediatric diabetes teams in a quality improvement collaborative together with access to a quality register, the quality of paediatric diabetes care can improve, thereby contributing to a reduced risk of late

    Communication is a crucial ingredient in every kind of collaborative work. But what is the least possible amount of communication required for a given task? We formalize this question by introducing a new framework for distributed computation, called {\\em oblivious protocols}. We investigate the power of this model by considering two concrete examples, the {\\em musical chairs} task $MC(n,m)$ and the well-known {\\em Renaming} problem. The $MC(n,m)$ game is played by $n$ players (processors) with $m$ chairs. Players can {\\em occupy} chairs, and the game terminates as soon as each player occupies a unique chair. Thus we say that player $P$ is {\\em in conflict} if some other player $Q$ is occupying the same chair, i.e., termination means there are no conflicts. By known results from distributed computing, if $m \\le 2n-2$, no strategy of the players can guarantee termination. However, there is a protocol with $m = 2n-1$ chairs that always terminates. Here we consider an oblivious protocol where in every time step ...

    In September 2013, the AACC International (AACI) Protein Technical Committee (now Protein and Enzymes Technical Committee) initiated a collaborative study of a method for the qualitative analysis of intact gluten in processed and nonprocessed corn products, using an R5 immunochromatographic dipstick system. It was validated to demonstrate that potential gluten-free products contain gluten lower than the Codex threshold of 20 mg/kg gluten. The results of the collaborative test with 18 participants confirmed that the method is suitable to detect gluten contaminations that are clearly lower than the threshold. It is recommended that the method be accepted by AOAC as Official First Action.

    Abstract Aim. The study aimed to describe genetical and clinical features of Attenuated Familial Adenomatous Polyposis (AFAP) and to propose clinical criteria and guidelines for treatment and surveillance. Method. A questionnaire study was carried out of polyposis registries with data on patients...... patients had a colectomy and an ileorectal anastomosis (IRA) and 5/82 (6%) had a secondary proctectomy. The location of the mutation in the APC gene was known in 69/171 (40%) tested patients. Only 15/29 (52%) of mutations in APC were found in parts of the gene usually associated with AFAP (the 5' end, exon...... 9 and 3' end). Conclusions. A subset of FAP patients with a milder phenotype does exist and treatment and surveillance should be modified accordingly. The mutation detection rate is lower than in classic FAP and mutations in AFAP patients are located throughout the APC gene. We propose the following...

    Full Text Available BACKGROUND: The association between change in weight or body mass index, and mortality is widely reported, however, both measures fail to account for fat distribution. Change in waist circumference, a measure of central adiposity, in relation to mortality has not been studied extensively. METHODS: We investigated the association between mortality and changes in directly measured waist circumference, hips circumference and weight from baseline (1990-1994 to wave 2 (2003-2007 in a prospective cohort study of people aged 40-69 years at baseline. Cox regression, with age as the time metric and follow-up starting at wave 2, adjusted for confounding variables, was used to estimate hazard ratios (HRs and 95% confidence intervals (CIs for change in body size in relation to mortality from all causes, cardiovascular disease and cancer. RESULTS: There were 1465 deaths (109 cancer, 242 cardiovascular disease identified during an average 7.7 years of follow-up from 21 298 participants. Compared to minimal increase in body size, loss of waist circumference (HR: 1.26; 95% CI: 1.09-1.47, weight (1.80; 1.54-2.11, or hips circumference (1.35; 1.15-1.57 were associated with an increased risk of all-cause mortality, particularly for older adults. Weight loss was associated with cardiovascular disease mortality (2.40; 1.57-3.65 but change in body size was not associated with obesity-related cancer mortality. CONCLUSION: This study confirms the association between weight loss and increased mortality from all-causes for older adults. Based on evidence from observational cohort studies, weight stability may be the recommended option for most adults, especially older adults.

    2010-05-01

    Full Text Available This paper discusses the journey toward self-managed education for the Innu people of coastal Labrador who, after an arduous struggle, have finally attained autonomy from the Canadian government. While the paper briefly explores the broader context within which Innu education has evolved, particular attention will be given to the role served by a recent research project in both documenting the specific educational needs of the people and presenting a process to guide change. What emerged from that study was a wealth of data including community attitudes to education, as well as indicators of attendance, ability and achievement of the entire population of school-aged children. The study documented significant learning needs among the school-aged population despite average cognitive ability and a desire to achieve well in school. A plethora of policy recommendations was presented to guide the creation of Innu-managed education as well as to establish a template for the creation of a bicultural model of education, one in which traditional culture and native language were prioritized. This paper explores the five-year impact of that study on both policy and practice for Aboriginal education in coastal Labrador. As such, it informs the establishment of policy and pedagogical approaches for educators attempting to balance contemporary educational opportunity with retention of core cultural values.

    The purpose of the present study was to pilot a prevention program designed to promote positive body image among university students. Thirty-seven undergraduate students from three Canadian universities were recruited to participate in the study. They were selected from a pool of students enrolled in a peer health education program facilitated by the university-based health promotion staff. Borrowing from the tenets of the non-specific vulnerability stressor model and the disease-specific social cognitive theory, the intervention focused on media literacy, self-esteem enhancement strategies, stress management skills and ways to recognize healthy versus unhealthy relationships. Separate ANOVAs revealed that participants reported significant improvements in body satisfaction and reductions in the internalization of media stereotypes between the baseline and post-program period. The program received a favorable response from the participating students, who appreciated the face-to-face format of the intervention, and from the university staff who expressed interest in embedding the strategies into their routine peer mentoring training activities. Limitations of the study and suggestions for future research are discussed.

    Full Text Available Abstract Background High-quality cancer information resources are available but underutilized by the public. Despite greater awareness of the National Cancer Institute's Cancer Information Service among low-income African Americans and Hispanics compared with Caucasians, actual Cancer Information Service usage is lower than expected, paralleling excess cancer-related morbidity and mortality for these subgroups. The proposed research examines how to connect the Cancer Information Service to low-income African-American and Hispanic women and their health care providers. The study will examine whether targeted physician mailing to women scheduled for colposcopy to follow up an abnormal Pap test can increase calls to the Cancer Information Service, enhance appropriate medical follow-up, and improve satisfaction with provider-patient communication. Methods/Design The study will be conducted in two clinics in ethnically diverse low-income communities in Chicago. During the formative phase, patients and providers will provide input regarding materials planned for use in the experimental phase of the study. The experimental phase will use a two-group prospective randomized controlled trial design. African American and Hispanic women with an abnormal Pap test will be randomized to Usual Care (routine colposcopy reminder letter or Intervention (reminder plus provider recommendation to call the Cancer Information Service and sample questions to ask. Primary outcomes will be: 1 calls to the Cancer Information Service; 2 timely medical follow-up, operationalized by whether the patient keeps her colposcopy appointment within six months of the abnormal Pap; and 3 patient satisfaction with provider-patient communication at follow-up. Discussion The study examines the effectiveness of a feasible, sustainable, and culturally sensitive strategy to increase awareness and use of the Cancer Information Service among an underserved population.

    Full Text Available Abstract Background Several studies have indicated a significant association between marital status and mortality risks. However, most of these studies have compared married and unmarried people without differentiating among single, divorced and widowed status. Moreover, gender differences in mortality rates associated with marital status have not been sufficiently clarified. With significant increases in the percentages of divorced and widowed people and a corresponding drop in the marriage rate in Japan during the past two or three decades, it can be expected that these changes will have a significant impact on mortality rates. Methods This investigation used a prospective study of a total of 94,062 Japanese men and women aged 40–79 who completed self-administered questionnaires at baseline and during a followed-up of 9.9-years. Results Compared with married men, never-married men showed higher risks of mortality from cardiovascular disease [relative risk (RR = 3.05, 95% confidence interval (CI 2.03–4.60], respiratory disease (RR = 2.43, 95%CI 1.27–4.63, external causes (RR = 2.18, 95%CI 1.05–4.54 and all causes (RR = 1.91, 95%CI 1.51–2.42 after adjustment for potentially confounding variables. For never-married women, there was a smaller but significantly higher risk of mortality from all causes (RR = 1.46, 95%CI 1.15–1.84. Divorced and widowed men showed moderately higher risks of mortality from cardiovascular disease, external causes and all causes compared with married men, but such a trend was not observed in women. Conclusion Single status was associated with a higher risk of mortality than was married status for both men and women. Divorce and widowhood were associated with elevated risk for men, but not for women. These findings suggest single, divorce and widowhood status constitute potentially adverse health effects.

    1980-03-01

    A new method has been developed for the extraction of light filth from oatmeal, barley, and mixed dry infant cereals which involves HCl digestion followed by wet sieving. The residue is defatted in a paper cup, using isopropanol, and transferred to a 2 L Wildman trap flask with 40% isopropanol. Filth elements are extracted with light mineral oil. Interlaboratory studies resulted in 92 and 86% average recoveries of rodent hairs and insect fragments, respectively. The proposed method has been adopted as official first action.

    1998-07-01

    The collaborative, anonymous, case-control study was intended to determine the prevalence of opiates, cocaine metabolites, cannabinoids and amphetamines in the urine of drivers injured in road accidents and to compare these values with those of non-accident subjects ("patients") in France. Recruitment was performed nationwide in the emergency departments of five hospitals and comprised 296 "drivers" aged 18 to 35 and 278 non-traumatic "patients" in the same age range. Females represented 28.4% of "drivers" and 44.2% of "patients." Screening for drugs in urine was performed by fluorescence polarization immunoassays in each center. Each positive result was verified using gas chromatography-mass spectrometry (GC-MS), in a single laboratory. Statistical analysis comprised single-step logistic regression and simultaneously took account of confounding factors and the final differences in prevalence values between the two populations or different subgroups. Cannabinoids were found in 13.9% of drivers (16.0% of males and 8.3% of females, p urine samples (NS), and were more frequent in urine samples positive for cannabinoids, in drivers (p amphetamines 1.4 and 2.5%, respectively. No causal relationship between drugs and accidents should be inferred from this retrospective study. Nevertheless, the high prevalence of cannabis and opiate (licit or illicit) use in young people, whether injured drivers or patients, has potential implications for road traffic safety in France. Cocaine and amphetamines did not appear to be a major problem, unlike the experience in other countries.

    Twenty-four laboratories participated in a collaborative study to validate a hydrophobic grid membrane filter (HGMF) method incorporating the use of 4-methylumbelliferyl-beta-D-glucuronide (MUG) for enumeration of total coliform and Escherichia coli bacteria in foods by comparing its performance against the AOAC 3-tube MPN method (46.013-46.016). Raw milk, raw ground poultry, whole egg powder, cheese powder, and ground black pepper were included in the study. The total coliform methods did not differ significantly, except that the 3-tube method detected a significantly higher level of total coliforms than did the HGMF method in the ground black pepper. Conversely, the HGMF/MUG E. coli method detected significantly higher numbers of E. coli present in the egg powder, cheese powder, and ground black pepper samples, while not differing significantly from the 3-tube method for the raw milk and raw ground poultry samples. The overall confirmation rate of MUG-positive colonies isolated using the HGMF method was 99.5%. The hydrophobic grid membrane filter/MUG method has been adopted official first action as an additional method to AOAC official final action method 46.030-46.034.

    This study presents results from a collaboration across five longitudinal studies seeking to test and replicate models of gene-environment interplay in the development of substance use and externalizing disorders (SUDs, EXT). We describe an overview of our conceptual models, plan for gene-environment interplay analyses, and present main effects results evaluating six candidate genes potentially relevant to SUDs and EXT (MAOA, 5-HTTLPR, COMT, DRD2, DAT1, and DRD4). All samples included rich longitudinal and phenotypic measurements from childhood/adolescence (ages 5-13) through early adulthood (ages 25-33); sample sizes ranged from 3487 in the test sample, to ~600-1000 in the replication samples. Phenotypes included lifetime symptom counts of SUDs (nicotine, alcohol and cannabis), adult antisocial behavior, and an aggregate externalizing disorder composite. Covariates included the first 10 ancestral principal components computed using all autosomal markers in subjects across the data sets, and age at the most recent assessment. Sex, ancestry, and exposure effects were thoroughly evaluated. After correcting for multiple testing, only one significant main effect was found in the test sample, but it was not replicated. Implications for subsequent gene-environment interplay analyses are discussed.

    Full Text Available The study aims to develop a screening protocol for the risk of future cardiovascular disease and diabetes mellitus in people with prediabetes and undiagnosed diabetes; and to establish a framework for early identification and intervention of prediabetes including strategies for holistic management and monitoring of progression. The first phase is to identify prediabetes and undiagnosed diabetes in volunteers who are ≥18-years-old for 5 years. Point-of-care testing and questionnaire will be used to screen for prediabetes and cardiovascular disease. We anticipate screening more than 2000 individuals of both genders by the end of first phase. The second and third phases which shall run for 5-10 years will be longitudinal study involving participants identified in the first phase as having prediabetes without dyslipidaemia, or clinically established cardiovascular disease. The second phase shall focus on preventive management of risk of progress to diabetes with explicit diagnosis of cardiovascular disease. Oxidative stress measurements will be performed cum evaluation of the use of antioxidants, exercise, and nutrition. The third phase will include probing the development of diabetes and cardiovascular disease. Binomial logistic regression would be performed to generate and propose a model chart for the assessment of cardiovascular disease risk in prediabetes.

    1991-09-01

    Interest in early thrombolysis has prompted a study on the feasibility and time course of prehospital thrombolysis in patients with acute myocardial infarction (AMI) in six centres in Belgium. Patients with clinically suspected AMI and with typical ECG changes presenting within 4 h after onset of pain were treated with 30 units of Anisoylated Plasminogen Streptokinase Activator Complex (APSAC, eminase) intravenously by a mobile intensive care unit (MICU). Sixty-two patients were included in the study and an AMI was confirmed in 60. The mean time (+/- 1 SD) from onset of pain to injection of APSAC was 95 +/- 47 min and the mean estimated time gain, calculated as the time difference between the arrival of the MICU at home and the arrival of the MICU at the emergency department, was 50 +/- 17 min. In the prehospital period four patients developed ventricular fibrillation and one cardiogenic shock. During hospital stay severe complications were observed in four patients. Two events were fatal, one diffuse haemorrhage and one septal rupture; two events were non fatal, one feasible and that an estimated time gain of 50 min can be obtained. Potential risks and benefits remain to be demonstrated in a large controlled clinical trial.

    2014-12-15

    Mercury (Hg) analyses were obtained for 42 samples of feed coal provided by Eskom, the national electric utility of South Africa, representing all 13 coal-fired power stations operated by Eskom in South Africa. This sampling includes results for three older power stations returned to service starting in the late 2000s. These stations were not sampled in the most recent previous study. Mercury concentrations determined in the present study are similar to or slightly lower than those previously reported, and input Hg for the three stations returned to service is comparable to that for the other 10 power stations. Determination of halogen contents of the 42 feed coals confirms that chlorine contents are generally low, and as such, the extent of Hg self-capture by particulate control devices (PCDs) is rather limited. Eight density separates of a South African Highveld (#4) coal were also provided by Eskom, and these show a strong mineralogical association of Hg (and arsenic) with pyrite. The density separates were used to predict Hg and ash contents of coal products used in South Africa or exported. A suite of 48 paired samples of pulverization-mill feed coal and fly ash collected in a previous (2010) United Nations Environment Programme-sponsored study of emissions from the Duvha and Kendal power stations was obtained for further investigation in the present study. These samples show that in each station, Hg capture varies by boiler unit and confirms that units equipped with fabric filters for air pollution control are much more effective in capturing Hg than those equipped with electrostatic precipitators. Apart from tracking the performance of PCDs individually, changes resulting in improved mercury capture of the Eskom fleet are discussed. These include Hg reduction through coal selection and washing, as well as through optimization of equipment and operational parameters. Operational changes leading to increased mercury capture include increasing mercury

    Despite being a classical growth disorder, pituitary gigantism has not been studied previously in a standardized way. We performed a retrospective, multicenter, international study to characterize a large series of pituitary gigantism patients. We included 208 patients (163 males; 78.4%) with growth hormone excess and a current/previous abnormal growth velocity for age or final height >2 s.d. above country normal means. The median onset of rapid growth was 13 years and occurred significantly earlier in females than in males; pituitary adenomas were diagnosed earlier in females than males (15.8 vs 21.5 years respectively). Adenomas were ≥10 mm (i.e., macroadenomas) in 84%, of which extrasellar extension occurred in 77% and invasion in 54%. GH/IGF1 control was achieved in 39% during long-term follow-up. Final height was greater in younger onset patients, with larger tumors and higher GH levels. Later disease control was associated with a greater difference from mid-parental height (r=0.23, P=0.02). AIP mutations occurred in 29%; microduplication at Xq26.3 - X-linked acrogigantism (X-LAG) - occurred in two familial isolated pituitary adenoma kindreds and in ten sporadic patients. Tumor size was not different in X-LAG, AIP mutated and genetically negative patient groups. AIP-mutated and X-LAG patients were significantly younger at onset and diagnosis, but disease control was worse in genetically negative cases. Pituitary gigantism patients are characterized by male predominance and large tumors that are difficult to control. Treatment delay increases final height and symptom burden. AIP mutations and X-LAG explain many cases, but no genetic etiology is seen in >50% of cases.

    2016-09-01

    Many research projects and scientific initiatives multiple their impact and relevance through collaborations. It is the contact and exchange with others that often brings a scientist's work to the next level. The same happens with outreach: sharing activities, concepts, materials and knowhow may lead to greater impact, more innovative, inspirational ideas with enough potential to create pioneering outreach activities. A good example for this is the FP7 European project "GoPhoton!", an initiative of ECOP (European Centres of Outreach in Photonics) that ran through 2014 and 2015 and finished at the beginning of 2016 and was directed at the general public, young minds as well as current and future entrepreneurs. This project was based on the idea of sharing activities - which is at the core of ECOP's identity- already existing in other nodes (institutions within the project), or created within GoPhoton! The main concept was the effective leverage of local links such as the networks of educators and professionals in general, industrial clusters, museums, universities, governmental and non-governmental organizations, all from a Pan-European perspective possible through ECOP. This has resulted in over 200 events impacting over two million people. The sharing of activities across institutions that have different resources, facilities, and cultural environments is not straightforward. One of the biggest challenges for the consortium was to be able to extract the concept and identity of each activity, so that it could be realistically adapted to each local context. A crucial point was being able to effectively use the knowhow gained from a partner's activity, in a way that the essence of the activity remained untainted across the participating nodes, while still triggering innovation locally.

    Since 1992, KAERI, AECL, United States Department of States(USDOS) and IAEA have performed the DUPIC fuel cycle development activities as an international cooperative research program, which has now been chosen as a target nuclear system for an INPRO case study. This study will focus on a further improvement and modification of the basic principles, user requirements and acceptance limits, which are defined in the IAEA-TECDOC-1434 for an evaluation of its proliferation-resistance through a proliferation-resistance assessment of the whole fuel cycle of DUPIC based on the INPRO methodology. In order to further develop an evaluation method for a proliferation-resistance based on the INPRO methodology, the basic principles, user requirements and acceptance limits of a proliferation-resistance was reviewed and quantified. Then the evaluation model (material flow, facility scale, reference fuel, etc.) of the DUPIC fuel cycle was developed and a proliferation-resistance assessment of the DUPIC fuel cycle including the PWR fuel cycle was performed by using the revised INPRO methodology in the area of a proliferation resistance. Also, the recommendations for a further improvement of INPRO methodology were suggested through examining the INPRO methodology for a proliferation resistance assessment. Through the proliferation resistance assessment of the whole fuel cycle of DUPIC including the PWR fuel cycle, the proliferation-resistance methodology was updated and re-established. And based on its experience, The research results can be used not only to evaluate and determine the future domestic proliferation-resistant fuel cycles which were derived from the GEN{sub I}V or INPRO programs but also to improve a system design to enhance its proliferation resistance. The present results will be utilized for the development of an INPRO User's Manual which is being developed as an important issue by IAEA. The credibility of the research results were ensured by the IAEA

    Full Text Available Advances in technology and changes in higher education and research are forcing libraries to rethink the services they offer to researchers and how they are presented. Librarians are moving into “higher end support” and adopting new service models based on “deep collaboration” with academic partners. The internal arrangements that form the design of an organization can determine whether it achieves its mission under particular conditions. The present study explores how libraries in 24 leading UK research universities are organizing resources and services to support the research enterprise. Qualitative data were collected from institutional websites and other public domain sources and were analysed using matrix techniques. The results show a trend away from integrated library and computing service organizations; variety in institutional reporting lines, but predominantly in large professional service groups; consistency in internal library groupings, but variation in portfolio and job titles; expansion of specialist positions, with new functional roles complementing traditional subject liaisons; and dedicated spaces, working groups, and integrated websites promoting boundary-spanning activities. The findings confirm and extend prior work and are being used to design a large scale international survey.

    During the last quarter of 1992, 984 patients from 13 dialysis centers in the Provence-Alpes-Côte-d'Azur region in France participated in a multicenter cross-sectional study to determine the prevalence, the risk factors, and the clinical consequences of infection by the hepatitis C virus (HCV). Serum samples were tested for anti-HCV antibodies using second-generation enzyme-linked immunosorbent assay (ELISA). In the case of a positive result, a combination test was performed using second-generation recombinant immunoblot (RIBA) or direct detection of HCV-RNA by nested polymerase chain reaction (PCR). Collected data included the patient's age, gender, cause of the kidney disease, type of dialysis treatment, number of years on dialysis, weekly dialysis time, drug addiction, co-infection with hepatitis B virus and human immunodeficiency virus (HIV), number of kidney transplants, number of blood transfusions, and history of acute or chronic hepatitis. Chronic HCV infection was detected in 232 (23.6%) patients, whereas only 71 (7.2%) were infected by HBV. Logistic-regression analysis showed that HCV infection was associated with dialysis over a long period, numerous blood transfusions, female gender, kidney grafts, HBV infection, hemodialysis, and acute as well as chronic hepatitis. Multiple-correspondence analysis confirmed that the contamination was both transfusional and nosocomial. These results underscore the need for a strict compliance with "universal precautions" (Centers for Disease Control [CDC], Atlanta) in dialysis units and raise the question as to whether anti-HCV-positive patients should be isolated.

    MedXViewer (Medical eXtensible Viewer) has been developed to address the need for workstation-independent, picture archiving and communication system (PACS)-less viewing and interaction with anonymised medical images. The aim of this paper is to describe the design and features of MedXViewer as well as to introduce the new features available in the latest release (version 1.2). MedXViewer currently supports digital mammography and tomosynthesis. The flexible software design used to develop MedXViewer allows it to be easily extended to support other imaging modalities. Regions of interest can be drawn by a user, and any associated information about a mark, an image or a study can be added. The questions and settings can be easily configured depending on the need of the research allowing both ROC and FROC studies to be performed. Complex tree-like questions can be asked where a given answer presents the user to new questions. The hanging protocol can be specified for each study. Panning, windowing, zooming and moving through slices are all available while modality-specific features can be easily enabled, e.g. quadrant zooming in digital mammography and tomosynthesis studies. MedXViewer can integrate with a web-based image database OPTIMAM Medical Image Database allowing results and images to be stored centrally. The software can, alternatively, run without a network connection where the images and results can be encrypted and stored locally on a machine or external drive. MedXViewer has been used for running remote paper-less observer studies and is capable of providing a training infrastructure and coordinating remote collaborative viewing sessions.

    Full Text Available The impacts of high technology industries have been growing increasingly to technological innovations and global economic developments, while the concerns in sustainability are calling for facilitating green materials and cleaner production in the industrial value chains. Today’s manufacturing companies are not striving for individual capacities but for the effective working with green supply chains. However, in addition to environmental and social objectives, cost and economic feasibility has become one of the most critical success factors for improving supply chain management with green component procurement collaboration, especially for the electronics OEM (original equipment manufacturing companies whose procurement costs often make up a very high proportion of final product prices. This paper presents a case study from the systems perspective by using System Dynamics simulation analysis and statistical validations with empirical data. Empirical data were collected from Taiwanese manufacturing chains—among the world’s largest manufacturing clusters of high technology components and products—and their global green suppliers to examine the benefits of green component procurement collaborations in terms of shared costs and improved shipping time performance. Two different supply chain collaboration models, from multi-layer ceramic capacitor (MLCC and universal serial bus 3.0 (USB 3.0 cable procurements, were benchmarked and statistically validated. The results suggest that the practices of collaborative planning for procurement quantity and accurate fulfillment by suppliers are significantly related to cost effectiveness and shipping time efficiency. Although the price negotiation of upstream raw materials for the collaborative suppliers has no statistically significant benefit to the shipping time efficiency, the shared cost reduction of component procurement is significantly positive for supply chain collaboration among green

    Zielsetzung: Das Medizinische Interprofessionelle Trainingszentrum der Medizinischen Fakultät Carl Gustav Carus an der Technischen Universität Dresden bietet seit dem Wintersemester 2014/2015 Lehrveranstaltungen mit interprofessionellen Inhalten an. Die Besonderheit dieser Lehreinheiten besteht darin, dass sowohl studentische TutorInnen der Medizin als auch SchülertutorInnen der Gesundheits- und Krankenpflege gemeinsam die Lehreinheiten betreuen. Die Studie untersucht das subjektive Erleben der TutorInnen während der gemeinsamen Ausarbeitung und Durchführung dieser Lehreinheiten mit dem Ziel, die Effekte der gleichberechtigten Zusammenarbeit auf die Wahrnehmung und Einschätzung der jeweils anderen Berufsgruppe herauszuarbeiten. Methode: Es wurden teilstrukturierte Leitfadeninterviews mit sechs zufällig ausgewählten TutorInnen durchgeführt. Diese werden mittels inhaltlich-strukturierender Inhaltsanalyse ausgewertet.Ergebnisse: Die Ergebnisse zeigen, dass das gemeinsame Arbeiten vor allem bei den studentischen TutorInnen zu einer Reflexion bestehender Einstellungen geführt hat, jedoch wurden die jeweiligen Co-TutorInnen bei beiden Berufsgruppen in unterschiedlichem Grad als Repräsentanten ihrer Profession wahrgenommen. Durch die Bewältigung einer gemeinsamen Aufgabe in einem nicht-klinischen Kontext begegneten sich die Angehörigen der verschiedenen Berufsgruppen auf Augenhöhe, wenngleich die Medizinstudierenden bereits mehr didaktische Erfahrung aufwiesen und somit im Zuge der Erarbeitung und der Umsetzung der Lehreinheiten meist eine Mentoren-Rolle übernahmen. Die SchülertutorInnen waren vorwiegend auf ihre Rolle als TutorIn konzentriert. Hervorgehoben wurde von beiden Berufsgruppen, dass sie vor der Zusammenarbeit mangelnde oder keine Vorstellungen bezüglich des theoretischen Wissens und der praktischen Fertigkeiten der jeweils anderen Berufsgruppe besaßen. Das Projekt insgesamt wurde als gewinnbringend eingeschätzt und der Ansatz der

    The Two Column Aerosol Project (TCAP) investigated uncertainties in the aerosol direct effect in the northern hemisphere mid-latitudes. The University of Colorado 2D-MAX-DOAS and LED-CE-DOAS instruments were collocated with DOE’s Atmospheric Radiation Measurement (ARM) Mobile Facility (AMF) and Mobile Aerosol Observing System (MAOS) during the TCAP-1 campaign at Cape Cod, MA (1 July to 13 August 2012). We have performed atmospheric radiation closure studies to evaluate the use of a novel parameter, i.e., the Raman Scattering Probability (RSP). We have performed first measurements of RSP almucantar scans, and measure RSP in spectra of scattered solar photons at 350nm and 430nm. Radiative Transfer Modelling of RSP demonstrate that the RSP measurement is maximally sensitive to infer even extremely low aerosol optical depth (AOD < 0.01) reliably by DOAS at low solar relative azimuth angles. We further assess the role of elevated aerosol layers on near surface observations of oxygen collision complexes, O 2-O2. Elevated aerosol layers modify the near surface absorption of O2-O2 and RSP. The combination of RSP and O2-O2 holds largely unexplored potential to better constrain elevated aerosol layers and measure column aerosol optical properties such as aerosol effective radius, extinction, aerosol phase functions and refractive indices. The TCAP deployment also provides a time series of reactive trace gas vertical profiles, i.e., nitrogen dioxide (NO2) and glyoxal (C2H2O2), which are measured simultaneously with the aerosol optical properties by DOAS. NO2 is an important precursor for ozone (O3) that modifies oxidative capacity. Glyoxal modifies oxidative capacity and is a source for brown carbon by forming secondary organic aerosol (SOA) via multiphase reactions in aerosol and cloud water. We have performed field measurements of these gases

    The McCleary enzymatic assay for mixed linkage (1-->3)(1-->4)-beta-D-glucans has been modified to apply to oat and barley fractions and ready-to-eat (RTE) cereals. The proposed method involves lower sample concentrations; stirring the samples; a longer, warmer lichenase digestion; and longer beta-glucosidase digestion. These changes result in higher recovery of beta-glucan. This modification expands on the American Association of Cereal Chemists (AACC) Method 32-22 by the addition of a desugaring procedure, which is necessary for RTE cereals. Results from collaborative studies sponsored by AACC and AOAC demonstrate good precision for an enzymatic assay. The average relative standard deviation for reproducibility (RSDR, a measure of interlaboratory variation) for 20 oat, barley, and cereal samples was 9.7%. The average RSD for repeatability (RSDr, intralaboratory variation) was 5.0%. The enzymatic method has been adopted first action by AOAC International for determination of beta-glucans in oat and barley fractions, and ready-to-eat cereals.

    Full Text Available Collaborative and community-based monitoring are becoming more frequent, yet few studies have examined the process and outcomes of these monitoring approaches. We studied 18 collaborative or community-based ecological assessment or monitoring projects undertaken by five community-based forestry organizations (CBFs, to investigate the objectives, process, and outcomes of collaborative ecological monitoring by CBF organizations. We found that collaborative monitoring can lead to shared ecological understanding among diverse participants, build trust internally and credibility externally, foster social learning and community-building, and advance adaptive management. The CBFs experienced challenges in recruiting and sustaining community participation in monitoring, building needed technical capacity for monitoring, and communicating monitoring results back to the broader community. Our results suggest that involving diverse and sometimes adversarial interests at key points in the monitoring process can help resolve conflicts and advance social learning, while also strengthening the link between social and ecological systems by improving the information base for management and increasing collective awareness of the interdependence of human and natural forest communities.

    Inactivated poliomyelitis vaccines are an important part of the World Health Organization (WHO) control strategy to eradicate poliomyelitis. Requirements for the quality control of poliomyelitis vaccines (inactivated) include the use of an in vitro D antigen quantification assay for potency determination on the final lot as outlined in the European Pharmacopoeia (Ph. Eur.) monograph 0214. Performance of this assay requires a reference preparation calibrated in International Units (IU). A Ph. Eur. biological reference preparation (BRP) for poliomyelitis vaccine (inactivated) calibrated in IU has been established for this purpose. Due to the dwindling stocks of batch 2 of the BRP a collaborative study was run as part of the European Directorate for the Quality of Medicines & HealthCare (EDQM) Biological Standardisation Programme to establish BRP batch 3 (BRP3). Twelve laboratories including Official Medicines Control Laboratories (OMCLs) and manufacturers participated. The candidate BRP3 (cBRP3) was from the same source and had the same characteristics as BRP batch 2 (BRP2). During the study the candidate was calibrated against the 3(rd) International Standard for inactivated poliomyelitis vaccine using in-house D antigen ELISA assays in line with the Ph. Eur. monograph 0214. The candidate was also compared to BRP2 to evaluate the continuity. Based on the results of the study, values of 320 DU/mL, 78 DU/mL and 288 DU/mL (D antigen units/mL) (IU) for poliovirus type 1, 2 and 3 respectively were assigned to the candidate. In June 2016, the Ph. Eur. Commission adopted the material as Ph. Eur. BRP for poliomyelitis vaccine (inactivated) batch 3.

    Although the benefits of integrating behavioral health (BH) services into primary care are well established (World Health Organization and World Organization of Family Doctors, 2012; Chiles et al. in Clin Psychol-Sci Pr 6:204-220, 1999; Cummings 1997; O'Donohue et al. 2003; Olfson et al. in Health Aff 18:79-93, 1999; Katon et al. in Ann Intern Med 124:917-925, 2001; Simon et al. in Arch Gen Psychiatry 52:850-856, 1995; Anderson et al. in Diabetes Care 24:1069-1078, 2001; Ciechanowski et al. in Arch Intern Med 160:3278-3285, 2000; Egede et al. in Diabetes Care 25:464-470, 2002), research has focused primarily on describing the types of interventions behavioral health providers (BHPs) employ rather than on reasons for referral, treatment initiation rates, or the patient characteristics that may impact them. This study presents the results of a multisite card study organized by The Collaborative Care Research Network, a subnetwork of the American Academy of Family Physicians' National Research Network devoted to conducting practice-based research focused on the provision of BH and health behavior services within primary care practices. The goals of the study included: (1) identifying the characteristics of patients referred for BH services; (2) codifying reasons for referral and whether patients were treated for the referral; (3) exploring any differences between patients who initiated BH contact and those who did not; and (4) assessing the types and frequency of BH services provided to patients who attended at least one appointment. Of the 200 patients referred to a BHP, 81 % had an initial contact, 71 % of which occurred on the same day. Men and women were equally likely to engage with a BHP although the time between appointments varied by gender. Depression and anxiety were the primary reasons for referral. Practice-based research is a viable strategy for advancing the knowledge about integrated primary care.

    The role of technology is an increasingly important resource in preparing students for the future. The Internet is a widely accessible tool. Technology has also made us more connected, allowing constant communication and instantaneous data sharing. Public utilities such as those found on the web, including blogs, are a means to convey scientific research in rapid, useful ways. This tool is ideal for newly emerging fields, allowing up-to-date collaboration and referencing of ongoing studies, as well as bringing students virtually into the field or laboratory through videos, pictures, and records of project work. Astrobiology is a high interest topic, integrating geology, chemistry, biology, and physics. Terrestrial Mars analog environments are compelling in that they shed light on unusual opportunities for diverse life in settings beyond Earth. For this study, the analog site locality is at the University of California-Davis McLaughlin Natural Reserve in the Coast Range Ophiolite, a portion of actively serpentinizing, uplifted oceanic material in northern California (see companion poster, McCann et al., Mineralogy of Surface Serpentinite Outcrops in the Coast Range Ophiolite: Implications for the Deep Biosphere and Astrobiology). Our research objective is to monitor the activity taking place within the subsurface biosphere through an interdisciplinary approach involving biogeochemists, microbiologists, organic geochemists, and geologists. The study of serpentinization with astrobiological ground-truthing is a relatively new and promising field. Scientific field procedures are constantly being modified as they are applied. In order to better collaborate study efforts, a daily field journal is being written, recording ideas, discussions, procedures, problems, solutions, and results. It serves as an informal report, including pictures and video clips of the field activity. The journal is maintained as an online blog for ease of use and accessibility, as well as public

    2014-10-01

    Adaptation and the adaptive capacity of human and environmental systems have been of central concern to natural and social science scholars, many of whom characterize and promote the need for collaborative cross-boundary systems that are seen as flexible and adaptive by definition. Researchers who study collaborative governance systems in the public administration, planning and policy literature have paid less attention to adaptive capacity specifically and institutional adaptation in general. This paper bridges the two literatures and finds four common dimensions of capacity, including structural arrangements, leadership, knowledge and learning, and resources. In this paper, we focus on institutional adaptation in the context of collaborative governance regimes and try to clarify and distinguish collaborative capacity from adaptive capacity and their contributions to adaptive action. We posit further that collaborative capacities generate associated adaptive capacities thereby enabling institutional adaptation within collaborative governance regimes. We develop these distinctions and linkages between collaborative and adaptive capacities with the help of an illustrative case study in watershed management within the National Estuary Program.

Their work needs to be synergistic, complementary to public services, and rooted in community mobilization and collective action. The study explores how an NGO and its health services are perceived by the population that it serves, and how it can contribute to reducing barriers to care. Design A qualitative exploratory study was conducted in remote Ecuador, characterized by its widespread poverty and lack of official governance. An international NGO collaborated closely with the public services to deliver preventative and curative health services. Data were collected using focus group discussions and semistructured interviews with purposively sampled community members, healthcare personnel, and community health workers based on their links to the health services. Conventional qualitative content analysis was used, focusing on manifest content. Results Emerging themes relate to the public private partnership (PPP), the NGO and its services, and community participation. The population perceives the NGO positively, linking it to healthcare improvements. Their priority is to get services, irrespective of the provider's structure. The presence of an NGO in the operation may contribute to unrealistic expectations of health services, affecting perceptions of the latter negatively. Conclusions To avoid unrealistic expectations and dissatisfaction, and to increase and sustain the population's trust in the organization, an NGO should operate in a manner that is as integrated as possible within the existing structure. The NGO should work close to the population it serves, with services anchored in the community.

    Full Text Available Gränsöverskridande Nordisk Undervisning/Utdanelse (GNU, meaning Cross-Border Nordic Education, the larger Nordic project, under which this case study was carried out, aims at developing innovative, cross-border teaching models in different subject domains in elementary school, including mathematics, language, science, social studies and history. This paper provides an in-depth description and analysis of how four social science and history elementary school teachers and their 70 students (5th–7th grades worked together between November 2011 and December 2012. Previous research regarding the use of information and communication technology (ICT in history education in elementary schools is limited, thus calling for contemporary investigations in this particular subject domain. The Technological Pedagogical Content Knowledge (TPACK model, enhancing the combination of teachers’ pedagogical, content and technical competence, was used as the analytical framework, together with nation-specific curricula and the European Union’s recommendations regarding students’ skills for lifelong learning. A range of empirical materials was analyzed, such as classroom observations, students’ video productions, texts and photos distributed and shared on a mutual blog, real-time interaction and teachers’ communication. The teachers tried out two ICT didactic models. In the asynchronous model, the major focus was on the form and content of the video productions being shared, whereas work with the synchronous model concentrated on the content and quality of the communication. Notwithstanding obstacles, cross-border collaboration provided added value. The nation-specific differences triggered curiosity and motivation to produce digital presentations of history content to be understood by the students in the three nations, facilitating goal fulfillment in communication skills and digital competence.

  6. Rethinking opportunities for special needs students to learn: A case study of collaboration between special and general educators

    Lamb, Margaret Ann

    This study tells the story of three teachers: Lyle (a veteran science teacher), Holly (a novice science teacher), and (Jane, a special education teacher) and their collaborative efforts to develop a science curriculum for all students including those with disabilities. All three of the teachers were members of Hart High School, a Professional Development School (PDS) affiliated with Michigan State University (MSU). Hart High School was involved in two simultaneous reform efforts: the merger of students with disabilities into general education classrooms and the restructuring of teaching and learning in core academic subjects for all students with the support of MSU and PDS resources. Evidence suggests that the school has achieved some success in fully including special needs students in general education classrooms which exceeds the national norms. Data indicates that students with disabilities are selecting more challenging advanced college preparatory courses in increasing numbers and maintaining an average grade point. The question this study addresses is: what resources--environmental as well as, moral and intellectual--contribute to a schools capacity to support students with special needs? In addressing the question, I examine the professional knowledge and pedagogical reasoning that characterize the three teachers (Lyle, Holly, and Jane) involved in transforming the general education curriculum to include all students. Further, I discuss in detail the beliefs that appear critical, if teachers are to address the needs of all students and thereby teach with a moral purpose. Finally, I address the environmental resources that seem necessary for teachers, like Lyle, Holly, and Jane not only to restructure, but reculture a school towards a moral ecology. Lastly, I describe some of the pitfalls that may await those who embark on similar journeys of reform.

    1995-01-01

    A joint AOAC/American Association of Cereal Chemists (AACC) collaborative study was conducted to determine by the Uppsala method the dietary fiber content and its composition in various foods. The method includes preparation of a residue by treatment with thermostable alpha-amylase and amyloglucosidase and then ethanol precipitation of solubilized dietary fiber components while leaving low-molecular weight carbohydrates in solution. After acid hydrolysis of residue, neutral polysaccharide residues are determined as alditol acetates by gas-liquid chromatography, uronic acid residues are determined by colorimetry, and ash-free acid-insoluble residue (Klason lignin) is determined gravimetrically. Total dietary fiber, including enzyme-resistant starch, is calculated as the sum of nonstarch polysaccharide residues and Klason lignin. Nine laboratories completed the study, analyzing in duplicate 8 unknown dried products that included 4 cereal products, green peas, potato fiber, carrots, and apples. Total dietary fiber contents of products tested ranged from 4.6 to 84.3%, with an average RSDR value of 8.4% (range, 4.8-11.1%). Total neutral polysaccharide residues ranged from 3.8 to 64.1%, with an average RSDR value of 7.5% (range, 5.4-10.5%). Individual neutral sugars (rhamnose, arabinose, xylose, mannose, galactose, and glucose) and uronic acid residues present at more than 1% generally had good RSDR values (3.3-22.8%), whereas, as expected for Klason lignin, only the wheat bran sample with a high content (16%) had an excellent RSDR value (5.0%). The gas chromatographic-colorimetric-gravimetric method (Uppsala method) for determination of total dietary fiber (as neutral sugar residues, uronic acid residues, and Klason lignin) has been adopted first action by AOAC INTERNATIONAL.

  11. Collaborative Tax Regulation

    DEFF Research Database (Denmark)

    Boll, Karen

    2016-01-01

    This article shows a new form of regulation within a tax administration where tax administrators abate tax evasion by nudging and motivating consumers to only purchase services from tax compliant businesses. This indirectly closes or forces tax evading businesses to change their practices, because...... their customer bases decline to commercially non-viable levels. The analysis is framed by public governance literature and argues that the regulation is an example of collaborative or interactive governance, because the tax administrators do not regulate non-compliance directly, but activate external...... implications for how tax practitioners think about collaborative and interactive regulatory initiatives. While the tax administration in the study sees the approach as effective, the analysis shows that there are a number of caveats in relation to regularity, public listing, costs and revenue focus...

    Roth, J N

    1988-01-01

    Ten laboratories participated in a collaborative study to compare the pectin-based plate count (PC) Redigel method with the aerobic plate count and standard plate count agar-based standard methods for the estimation of total bacterial counts in 9 different nondairy food and dairy food products. The foods were cream, homogenized milk, raw milk, cheese, raw chicken, raw oysters, frozen broccoli, flour, and spices. Each laboratory analyzed 6 samples (3 sample pairs) of each food group. Counts obtained by the pectin-based plate count and agar-based plate count methods differed significantly (P less than 0.05) only for homogenized milk, where the pectin gel method resulted in higher counts. The actual counts were higher in the pectin gel method in 8 of the 9 food groups. The log means for pectin gel and agar-based media, respectively, for the 9 food groups were: cream 8.106 and 7.844; homogenized milk 8.642 and 8.231; raw milk 8.711 and 8.423; chicken 7.654 and 7.645; oysters 7.201 and 7.180; broccoli 7.102 and 6.798; cheese 8.045 and 8.055; flour 4.112 and 3.988; spice 5.379 and 5.314. The repeatability standard deviations favored the pectin gel method in 6 of the 9 foods tested. The reproducibility standard deviations favored the pectin gel method in 7 of the 9 foods tested. These results strongly support the suitability of the pectin gel method as an alternative to agar-based plate count and other methods for total bacterial counts in nondairy and dairy food products. The pectin gel method has been adopted official first action.

    Vascular cognitive impairment (VCI), including its severe form, vascular dementia (VaD), is the second most common form of dementia. The genetic etiology of sporadic VCI remains largely unknown. We previously conducted a systematic review and meta-analysis of all published genetic association studies of sporadic VCI prior to 6 July 2012, which demonstrated that APOE (ɛ4, ɛ2) and MTHFR (rs1801133) variants were associated with susceptibility for VCI. De novo genotyping was conducted in a new independent relatively large collaborative European cohort of VaD (nmax = 549) and elderly non-demented samples (nmax = 552). Where available, genotype data derived from Illumina's 610-quad array for 1210 GERAD1 control samples were also included in analyses of genes examined. Associations were tested using the Cochran-Armitage trend test: MTHFR rs1801133 (OR = 1.36, 95% CI 1.16-1.58, p = <0.0001), APOE rs7412 (OR = 0.62, 95% CI 0.42-0.90, p = 0.01), and APOE rs429358 (OR = 1.59, 95% CI 1.17-2.16, p = 0.003). Association was also observed with APOE epsilon alleles; ɛ4 (OR = 1.85, 95% CI 1.35-2.52, p = <0.0001) and ɛ2 (OR = 0.67, 95% CI 0.46-0.98, p = 0.03). Logistic regression and Bonferroni correction in a subgroup of the cohort adjusted for gender, age, and population maintained the association of APOE rs429358 and ɛ4 allele.

  14. Determination of total dietary fiber (CODEX definition) by enzymatic-gravimetric method and liquid chromatography: collaborative study.

    McCleary, Barry V; DeVries, Jonathan W; Rader, Jeanne I; Cohen, Gerald; Prosky, Leon; Mugford, David C; Champ, Martine; Okuma, Kazuhiro

    2010-01-01

    A method for the determination of total dietary fiber (TDF), as defined by the CODEX Alimentarius, was validated in foods. Based upon the principles of AOAC Official Methods 985.29, 991.43, 2001.03, and 2002.02, the method quantitates high- and low-molecular-weight dietary fiber (HMWDF and LMWDF, respectively). In 2007, McCleary described a method of extended enzymatic digestion at 37 degrees C to simulate human intestinal digestion followed by gravimetric isolation and quantitation of HMWDF and the use of LC to quantitate low-molecular-weight soluble dietary fiber (LMWSDF). The method thus quantitates the complete range of dietary fiber components from resistant starch (by utilizing the digestion conditions of AOAC Method 2002.02) to digestion resistant oligosaccharides (by incorporating the deionization and LC procedures of AOAC Method 2001.03). The method was evaluated through an AOAC collaborative study. Eighteen laboratories participated with 16 laboratories returning valid assay data for 16 test portions (eight blind duplicates) consisting of samples with a range of traditional dietary fiber, resistant starch, and nondigestible oligosaccharides. The dietary fiber content of the eight test pairs ranged from 11.57 to 47.83%. Digestion of samples under the conditions of AOAC Method 2002.02 followed by the isolation and gravimetric procedures of AOAC Methods 985.29 and 991.43 results in quantitation of HMWDF. The filtrate from the quantitation of HMWDF is concentrated, deionized, concentrated again, and analyzed by LC to determine the LMWSDF, i.e., all nondigestible oligosaccharides of degree of polymerization > or =3. TDF is calculated as the sum of HMWDF and LMWSDF. Repeatability standard deviations (Sr) ranged from 0.41 to 1.43, and reproducibility standard deviations (S(R)) ranged from 1.18 to 5.44. These results are comparable to other official dietary fiber methods, and the method is recommended for adoption as Official First Action.

    The ColiComplete substrate supporting disc (SSD) method for simultaneous confirmed total coliform count and Escherichia coli determination in all foods was compared with AOAC most probable number (MPN) methods, 966.23 and 966.24. Twenty-nine laboratories participated in this collaborative study in which 6 food types were analyzed. Four food types, raw ground beef, pork sausage, raw liquid milk, and nut meats, were naturally contaminated with coliform bacteria. Two foods, dry egg and fresh frozen vegetables, were seeded with coliforms. Three food types, ground beef, raw liquid milk, and pork sausage, were naturally contaminated with E. coli. Although pork sausage was naturally contaminated, the level was very low (food type. Three food types, nut meats, dry egg, and fresh frozen vegetables, were inoculated with E. coli. For naturally contaminated samples, duplicate determinations were made on 3 separate lots for each food type. For inoculated samples, low, medium, and high contamination levels plus uninoculated control samples were examined in duplicate. Data were analyzed separately for total coliform bacteria and for E. coli. Mean log MPN counts were determined by the SSD method and the appropriate AOAC MPN method. Results were then analyzed for repeatability, reproducibility, and mean log MPN statistical equivalence. Results were statistically equivalent for all total coliform levels in all food types except frozen vegetable and raw nut meat uninoculated control samples and 1 lot of pork sausage where the SSD method produced statistically significant greater numbers. For the E. coli determinations, results were statistically equivalent across all samples and all levels for each food type. The SSD method has been adopted first action by AOAC International for confirmed detection of total coliforms and E. coli in all foods.

  16. Developing a collaborative multimedia learning platform for GIScience education: A case study in designing an interactive textbook for iPad

    Science.gov (United States)

    Paloma, Cynthia S.

    Geographic information science (GIScience) is a constantly evolving field, posing a challenge to the production of current and affordable GIScience education textbooks. The content of printed textbooks has long been replicated in digital format, but the addition of interactive multimedia elements which support the content enhances the learning experience through engagement of multiple senses. The availability of interactive multimedia textbooks on mobile devices affords greater portability and accessibility. GIScience education in particular benefits from the inclusion of multimedia elements such as maps, images and videos. While digital publishing has potential for timely updates and rapid dissemination, individual authors generally have limited time and resources to update textbooks, especially when incorporating interactive multimedia elements. Collaboration is one approach to meeting this challenge; by working in parallel on an interactive multimedia textbook guided by pedagogy, collaborators can expedite the development and publishing process. This research discusses initial development of a free prototype interactive multimedia textbook for GIScience on Apple iPad (hereinafter "GIScience iBook" or "prototype") and a collaborative framework to support ongoing content development. There are three research questions in this study: (1) What are the major technical challenges in designing and implementing the prototype and content development framework? (2) How to assess and evaluate the prototype for an audience of undergraduate university students taking their first GIS class? (3) Who are the collaborative participants in the GIScience education community and what are their motivations, experiences and user profiles? The development process resulted in the GIScience iBook prototype, consisting of two chapters, as well as a contribution framework implemented on the Plone Content Management System (CMS). Technical challenges include the proprietary nature of the

    This paper describes a distributed collaborative effort between industry and academia to systematize data management in an academic biomedical laboratory. Heterogeneous and voluminous nature of research data created in biomedical laboratories make information management difficult and research unproductive. One such collaborative effort was evaluated over a period of four years using data collection methods including ethnographic observations, semi-structured interviews, web-based surveys, progress reports, conference call summaries, and face-to-face group discussions. Data were analyzed using qualitative methods of data analysis to (1) characterize specific problems faced by biomedical researchers with traditional information management practices, (2) identify intervention areas to introduce a new research information management system called Labmatrix, and finally to (3) evaluate and delineate important general collaboration (intervention) characteristics that can optimize outcomes of an implementation process in biomedical laboratories. Results emphasize the importance of end user perseverance, human-centric interoperability evaluation, and demonstration of return on investment of effort and time of laboratory members and industry personnel for success of implementation process. In addition, there is an intrinsic learning component associated with the implementation process of an information management system. Technology transfer experience in a complex environment such as the biomedical laboratory can be eased with use of information systems that support human and cognitive interoperability. Such informatics features can also contribute to successful collaboration and hopefully to scientific productivity.

  9. Proactive Assessment for Collaboration Success

    Teresa L. Ju

    2014-07-01

    Full Text Available This study describes a government–academia–industry joint training project that produces Vietnamese midlevel technical managers. To ensure collaboration success, a proactive assessment methodology was developed as a supplement to the conventional project management practices. In the postproject feedback, the funding agencies acknowledged that the project fulfilled its contractual obligations and achieved its objectives. The implementing university was pleased as it broke ground in this type of collaboration in Taiwan. The industrial partners, however, were not so sure about the effectiveness of this collaborative training endeavor because there were many skirmishes between company supervisors and Vietnamese interns caused by the interns’ self-interested perception and expectation. Consequently, a theoretical framework for predicting internship acceptance and preventing unfavorable perceptions was proposed to strengthen the proactive assessment methodology. Collaboration research, funding agencies, academia, and industry could all benefit from this study.

    2004-01-01

    A collaborative study on the evaluation of an alternative functional assay, the Vero cell method, to the Ph. Eur. in vivo challenge procedures for potency determination of diphtheria toxoid in 6 different combined vaccines was initiated in January 2001. The study was an extension of a previous study for the validation of serological methods for potency testing of tetanus toxoid vaccines for human use. To allow interim evaluation of test results and to monitor study progress, the project was divided into three consecutive phases. The results of Phase I and II studies are presented in this report. Pre-validation (Phase I) study, performed in two laboratories, indicated that comparable diphtheria potency estimates were obtained in the Ph. Eur. direct intradermal challenge assay in guinea pigs, in Vero cell assay and in indirect ELISA for five vaccines of different potencies (range of estimates: ca. 20-200 IU/ml). The correlation coefficients between the challenge assay and the Vero cell assay corresponded to those between the challenge assay and ELISA, confirming that the antibodies play an important role in protection and that predominantly protective/neutralising antibodies are present in guinea pigs, at the time point investigated. It was observed, for Vero cell assays, that about 16-35 (9-28 in Phase II study) fold lower titre of individual serum samples were obtained when using equine, rather than guinea pig reference serum. The study also provided preliminary information that sera from the same guinea pigs may be used for potency determination of both diphtheria and tetanus toxoid components of vaccines. In Phase II, another five laboratories analysed a subset of the vaccines included in Phase I study plus an additional vaccine. Four laboratories performed the lethal challenge assay and one laboratory carried out the intradermal challenge assay. All laboratories also performed the Vero cell assay and both ELISA for diphtheria antitoxin and ELISA for tetanus

A total of 695 adults including 259 healthy volunteers and 436 CKD patients were recruited. Participants from the Kaohsiung Medical University Hospital were used as the development set (N = 556 to develop the Taiwanese eGFR equations, whereas participants from the National Taiwan University Hospital were used as the validation set (N = 139 for external validation.The Taiwanese eGFR equations were developed by using the extended Bland-Altman plot in the development set. The Taiwanese MDRD equation was 1.309 × MDRD0.912, Taiwanese CKD-EPI was 1.262×CKD-EPI0.914 and Taiwanese four-level CKD-EPI was 1.205 × four-level CKD-EPI0.914. In the validation set, the Taiwanese equations had the lowest bias, the Taiwanese equations and the Japanese CKD-EPI equation had the lowest RMSE, whereas the Taiwanese and the Japanese equations had the best precision and the highest P30 among all equations. However, the Taiwanese MDRD equation had higher concordance correlation than did the Taiwanese CKD-EPI, the Taiwanese four-level CKD-EPI and the Japanese equations. Moreover, only the Taiwanese equations had no proportional bias among all of the equations. Finally, the Taiwanese MDRD equation had the best diagnostic performance in terms of ordinal logistic regression among all of the equations.The Taiwanese MDRD equation is better than the MDRD, CKD-EPI, Japanese, Asian, Thai, Taiwanese CKD-EPI, and Taiwanese four-level CKD-EPI equations for Taiwanese adults.

    2002-01-01

    A rehydratable dry-film plating method for coliforms in foods, the 3M Petrifilm Rapid Coliform Count plate method, was compared with the U.S. Food and Drug Administration's Bacteriological Analytical Manual method for nondairy foods and the American Public Health Association's Standard Methods for the Examination of Dairy Products (SMEDP) method for dairy foods. Six food types, vanilla ice cream, cheddar cheese, fresh refrigerated uncooked pasta, wheat flour, prepared frozen macaroni and cheese, and frozen hash browns, were analyzed for coliforms by 11 collaborating laboratories. For each food product tested, the collaborators received 8 blind samples consisting of a control sample and 3 levels of inoculated sample, each in duplicate. The mean log counts for the methods were comparable. The repeatability and reproducibility variances of the Petrifilm Rapid Coliform Count method at 14 and 24 h were not significantly different from those of the standard methods.

    The 3M Petrifilm Staph Express Count plate method was compared with AOAC Official Method 975.55 for the enumeration of Staphylococcus aureus in selected foods. Five foods--ice cream, raw milk, yogurt, whey powder, and cheese--were analyzed for S. aureus by 12 collaborating laboratories. For each food tested, the collaborators received 8 blind test samples consisting of a control sample, a low inoculation level, a medium inoculation level, and a medium inoculation level with background flora, each in duplicate. The mean log10 counts for the methods were comparable for all 5 foods. The repeatability and reproducibility variances of the 24 h Petrifilm Staph Express Count plate method were similar to those of the 72 h standard method.

    Full Text Available Abstract Background Cystic fibrosis (CF is caused by mutations in the gene encoding for the CF transmembrane conductance regulator (CFTR protein, which acts as a chloride channel after activation by cyclic AMP (cAMP. Newborn screening programs for CF usually consist of an immunoreactive trypsinogen (IRT assay, followed when IRT is elevated by testing for a panel of CF-causing mutations. Some children, however, may have persistent hypertrypsinogenemia, only one or no identified CFTR gene mutation, and sweat chloride concentrations close to normal values. In vivo demonstration of abnormal CFTR protein function would be an important diagnostic aid in this situation. Measurements of transepithelial nasal potential differences (NPD in adults accurately characterize CFTR-related ion transport. The aim of the present study is to establish reference values for NPD measurements for healthy children and those with CF aged 3 months to 3 years, the age range of most difficult-to-diagnose patients with suspected CF. The ultimate goal of our study is to validate NPD testing as a diagnostic tool for children with borderline results in neonatal screening. Methods/Design We adapted the standard NPD protocol for young children, designed a special catheter for them, used a slower perfusion rate, and shortened the protocol to include only measurement of basal PD, transepithelial sodium (Na+ transport in response to the Na+ channel inhibitor amiloride, and CFTR-mediated chloride (Cl- secretion in response to isoproterenol, a β-agonist in a Cl- free solution. The study will include 20 children with CF and 20 healthy control children. CF children will be included only if they carry 2 CF-causing mutations in the CFTR gene or have sweat chloride concentrations > 60 mEq/L or both. The healthy children will be recruited among the siblings of the CF patients, after verification that they do not carry the familial mutation. Discussion A preliminary study of 3 adult control

    Phase I of BSP034 collaborative study was extended in two laboratories to include correlation of serology with in vivo toxin neutralisation test (TNT) using 2 separate sets of 20 serum pools, produced in-house. The study investigated the extent to which the in vitro methods for diphtheria antibodies, Vero cell assay and diphtheria enzyme-linked immunosorbent assay for diphtheria antitoxin (D-ELISA), can detect neutralising antibodies by comparison with TNT in guinea pigs. The study was also performed to compare the antibody neutralising potency obtained in relation to guinea pig (GP) or equine (DI) antitoxin standard. In addition, the study provided an opportunity to compare ELISA for tetanus antitoxin (T-ELISA) and TNT assay for detection of anti-tetanus antibodies, from the same set of serum pools. The data obtained show that antitoxin potency obtained by Vero cell assay, D-ELISA and T-ELISA using the same GP standard, highly correlated with neutralising potency as determined in respective TNT assays. Vero cell assay with DI provided estimates that also correlated with neutralising potency, but were of significantly lower titre. Since reference to DI standard is widely used in serodiagnosis, as well as in clinical studies where diphtheria antitoxin titres obtained in the Vero cell method are taken as surrogate markers for vaccine efficacy, it should be investigated if a similar difference is also observed for human serology.

    2016-01-01

    To address the invasion of non-native Phragmites in the Great Lakes, researchers at the U.S. Geological Survey—Great Lakes Science Center partnered with the Great Lakes Commission in 2012 to establish the Great Lakes Phragmites Collaborative (GLPC). The GLPC is a regional-scale partnership established to improve collaboration among stakeholders and increase the effectiveness of non-native Phragmites management and research. Rather than forming a traditional partnership with a narrowly defined goal, the GLPC follows the principles of collective impact to engage stakeholders, guide progress, and align resources to address this complex, regional challenge. In this paper, the concept and tenets of collective impact are described, the GLPC is offered as a model for other natural resource-focused collective impact efforts, and steps for establishing collaboratives are presented. Capitalizing on the interactive collective impact approach, the GLPC is moving toward a broadly accepted common agenda around which agencies and individuals will be able to better align their actions and generate measureable progress in the regional campaign to protect healthy, diverse ecosystems from damage caused by non-native Phragmites.

    Full Text Available Osteoarthritis is the leading cause of total hip replacement, accounting for more than 80% of all total hip replacements. Emerging evidence suggests that osteoarthritis has a chronic inflammatory component to its pathogenesis similar to age-related macular degeneration. We evaluated the association between age-related macular degeneration and total hip replacement as proxy for severe osteoarthritis or fractured neck of femur in the Melbourne Collaborative Cohort Study. 20,744 participants had complete data on both age-related macular degeneration assessed from colour fundus photographs taken during 2003-2007 and total hip replacement. Total hip replacements due to hip osteoarthritis and fractured neck of femur during 2001-2011 were identified by linking the cohort records to the Australian Orthopedic Association National Joint Replacement Registry. Logistic regression was used to examine the association between age-related macular degeneration and risk of total hip replacement due to osteoarthritis and fracture separately, adjusted for confounders. There were 791 cases of total hip replacement for osteoarthritis and 102 cases of total hip replacement due to fractured neck of femur. After adjustment for age, sex, body mass index, smoking, and grouped country of birth, intermediate age-related macular degeneration was directly associated with total hip replacement for osteoarthritis (odds ratio 1.22, 95% CI 1.00-1.49. Late age-related macular degeneration was directly associated with total hip replacement due to fractured neck of femur (odds ratio 5.21, 95% CI2.25-12.02. The association between intermediate age-related macular degeneration and an increased 10-year incidence of total hip replacement due to osteoarthritis suggests the possibility of similar inflammatory processes underlying both chronic diseases.

    A method for the determination of insoluble (IDF), soluble (SDF), and total dietary fiber (TDF), as defined by the CODEX Alimentarius, was validated in foods. Based upon the principles of AOAC Official Methods 985.29, 991.43, 2001.03, and 2002.02, the method quantitates water-insoluble and water-soluble dietary fiber. This method extends the capabilities of the previously adopted AOAC Official Method 2009.01, Total Dietary Fiber in Foods, Enzymatic-Gravimetric-Liquid Chromatographic Method, applicable to plant material, foods, and food ingredients consistent with CODEX Definition 2009, including naturally occurring, isolated, modified, and synthetic polymers meeting that definition. The method was evaluated through an AOAC/AACC collaborative study. Twenty-two laboratories participated, with 19 laboratories returning valid assay data for 16 test portions (eight blind duplicates) consisting of samples with a range of traditional dietary fiber, resistant starch, and nondigestible oligosaccharides. The dietary fiber content of the eight test pairs ranged from 10.45 to 29.90%. Digestion of samples under the conditions of AOAC 2002.02 followed by the isolation, fractionation, and gravimetric procedures of AOAC 985.29 (and its extensions 991.42 and 993.19) and 991.43 results in quantitation of IDF and soluble dietary fiber that precipitates (SDFP). The filtrate from the quantitation of water-alcohol-insoluble dietary fiber is concentrated, deionized, concentrated again, and analyzed by LC to determine the SDF that remains soluble (SDFS), i.e., all dietary fiber polymers of degree of polymerization = 3 and higher, consisting primarily, but not exclusively, of oligosaccharides. SDF is calculated as the sum of SDFP and SDFS. TDF is calculated as the sum of IDF and SDF. The within-laboratory variability, repeatability SD (Sr), for IDF ranged from 0.13 to 0.71, and the between-laboratory variability, reproducibility SD (SR), for IDF ranged from 0.42 to 2.24.

    Full Text Available This paper explores the use of Web 2.0 technologies for collaborative learning in a higher education context. A review of the literature exploring the strengths and weaknesses of Web 2.0 technology is presented, and a conceptual model of a Web 2.0 community of inquiry is introduced. Two Australian case studies are described, with an ex-poste evaluation of the use of Web 2.0 tools. Conclusions are drawn as to the potential for the use of Web 2.0 tools for collaborative e-learning in higher education. In particular, design and integration of Web 2.0 tools should be closely related to curriculum intent and pedagogical requirements, care must be taken to provide clear guidance on both expected student activity and learning expectations, and there is a clear need to develop, support and encourage strong interaction both between teachers and students, and amongst the students themselves.

    Full Text Available The objective of this paper is to present a collaborative research process between the Nonuya indigenous community and western scientists whilst studying fruit production patterns and the role of animals in the spatial distribution patterns of terra firme rain forest tree species in the Colombian Amazon. The process is presented in four stages: initially with a distant relationship between western scientists and indigenous people, with little exchange of knowledge, which progressed into a collaborative research relationship involving a high exchange of knowledge. The first stage consisted of the indigenous people's participation an exclusively scientific research project on natural sciences, as passive fieldwork guides. The second stage occurred when the guide became a fieldwork assistant and received training and expertise in scientific methodologies for data collection. The relationship between western scientists and indigenous people developed into the ability to have frequent debates and discussions over observations, findings, and interpretations. In the third stage, the indigenous fieldwork assistant proposed his own research, wherein he combined both scientific methodologies, and dialogue with elders in order to obtain information. During the fourth stage of the process, high quality information, relevant to the needs of both the western scientists and indigenous people was generated. This collaborative research process allowed the exchange of experiences, methodologies, and learning, leading to a better understanding of tropical rainforests. In this paper, the implications of this experience for future studies with the indigenous communities are discussed.

    Full Text Available This case study analyzes coauthorship collaboration, or lack thereof, among individual faculty members and departments in the School of Biology and Biotechnology of the National University of Mongolia. I found that publication rates and coauthorship networks in impact-factor journals between 2008 and 2012 (as of October 31, 2012 are highly variable among the eight biology departments we studied, both within and among departments. Even in the best cases, publication rates and coauthorship networks were not suffi cient. We call such insuffi cient coauthorship collaboration among different departments as (nonnetwork of coauthorship. The size of departments and observed coauthorship networks (both connectance and linkage density appear to positively, although insignifi cantly, affect not only the total number of publications, but also the publication rate per faculty per year. We suggest that this kind of analysis can be important for administration of academic institutions, for improving the scientifi c outputs of academic entities by facilitating collaborative efforts and for rationalizing organizational structures and merit-based promotion systems for more productive and effi cient academic operations.

    Global Collaborative STEM Education, as the name suggests, simultaneously supports two sets of knowledge and skills. The first set is STEM -- science, technology, engineering and math. The other set of content knowledge and skills is that of global collaboration. Successful global partnerships require awareness of one's own culture, the biases embedded within that culture, as well as developing awareness of the collaborators' culture. Workforce skills fostered include open-mindedness, perseverance when faced with obstacles, and resourceful use of technological "bridges" to facilitate and sustain communication. In respect for the 2016 GIFT Workshop focus, Global Collaborative STEM Education projects dedicated to astronomy research will be presented. The projects represent different benchmarks within the Global Collaborative STEM Education continuum, culminating in an astronomy research experience that fully reflects how the global STEM workforce collaborates. To facilitate wider engagement in Global Collaborative STEM Education, project summaries, classroom resources and contact information for established international collaborative astronomy research projects will be disseminated.

    Full Text Available Brittany H Eghaneyan,1 Katherine Sanchez,2 Diane B Mitschke2 1Department of Psychiatry, UT Southwestern Medical Center, Dallas, TX, USA; 2School of Social Work, The University of Texas at Arlington, Arlington, TX, USA Background: The collaborative care model is a systematic approach to the treatment of depression and anxiety in primary care settings that involves the integration of care managers and consultant psychiatrists, with primary care physician oversight, to more proactively manage mental disorders as chronic diseases, rather than treating acute symptoms. While collaborative care has been shown to be more effective than usual primary care in improving depression outcomes in a number of studies, less is known about the factors that support the translation of this evidence-based intervention to real-world program implementation. The purpose of this case study was to examine the implementation of a collaborative care model in a community based primary care clinic that primarily serves a low-income, uninsured Latino population, in order to better understand the interdisciplinary relationships and the specific elements that might facilitate broader implementation. Methods: An embedded single-case study design was chosen in order to thoroughly examine the components of one of several programs within a single organization. The main unit of analysis was semi-structured interviews that were conducted with seven clinical and administrative staff members. A grounded theory approach was used to analyze the interviews. Line-by-line initial coding resulted in over 150 initial codes, which were clustered together to rebuild the data into preliminary categories and then divided into four final categories, or main themes. Results: Four unique themes about how the implementation of a collaborative care model worked in this setting emerged from the interviews: organizational change, communication, processes and outcomes of the program, and barriers to

    2015-01-01

    Starch, glycogen, maltooligosaccharides, and other α-1,4- and α-1,6-linked glucose carbohydrates, exclusive of resistant starch, are collectively termed "dietary starch". This nutritionally important fraction is increasingly measured for use in diet formulation for animals as it can have positive or negative effects on animal performance and health by affecting energy supply, glycemic index, and formation of fermentation products by gut microbes. AOAC Method 920.40 that was used for measuring dietary starch in animal feeds was invalidated due to discontinued production of a required enzyme. As a replacement, an enzymatic-colorimetric starch assay developed in 1997 that had advantages in ease of sample handling and accuracy compared to other methods was considered. The assay was further modified to improve utilization of laboratory resources and reduce time required for the assay. The assay is quasi-empirical: glucose is the analyte detected, but its release is determined by run conditions and specification of enzymes. The modified assay was tested in an AOAC collaborative study to evaluate its accuracy and reliability for determination of dietary starch in animal feedstuffs and pet foods. In the assay, samples are incubated in screw cap tubes with thermostable α-amylase in pH 5.0 sodium acetate buffer for 1 h at 100°C with periodic mixing to gelatinize and partially hydrolyze α-glucan. Amyloglucosidase is added, and the reaction mixture is incubated at 50°C for 2 h and mixed once. After subsequent addition of water, mixing, clarification, and dilution as needed, free + enzymatically released glucose are measured. Values from a separate determination of free glucose are subtracted to give values for enzymatically released glucose. Dietary starch equals enzymatically released glucose multiplied by 162/180 (or 0.9) divided by the weight of the as received sample.

    Full Text Available Objective – The study attempted to apply the strategies of social marketing theory to collaboration between school librarians andteachers. Design – Based on the 1972 theory of social marketing by Zaltman, Kotler and Kaufman, a cohort of students in a graduate-level practicum established a collaborative unit with selected teachers within their school. In addition, two focus groups were conducted in alternate schools to gauge the overall attitudes of teachers toward collaboration with school librarians.Subjects – Students (student librarians in a graduate-level certification class for Texas school librarians, and both teachers and librarians in host schools/districts for the graduate students’ practicum experiences Methods – Researchers used qualitative approaches, both case study and focus groups, to gather data about the collaborative interactions between teachers and school librarians. The interactions were designed using the social marketing AIDA model (Attention, Interest, Desire, and Action. Social marketing, based on models of commercial marketing, assumes that social goodwill is a motivator for establishing interactions between groups – or selling a service that is for the greater good. Students in a graduate-level practicum were instructed to develop a strategy based on the AIDA model to elicit and carry out a collaborative unit with teachers in their host schools. They were given specific guidelines by the principal investigators that included:• Instructions for designing announcements, leaflets, and conferences as marketing strategies • Instructional unit designs for subject content and information literacy skills• Incentive payments of $200 to be used for library resources as anincentive to collaborate.• The steps to engaging in the collaborative process • Procedural guidelines for taking field notes, unobtrusive observations and informal evidence.Summative evaluation was based on a reflective journaling exercise

    To examine whether NMR analysis is a suitable method for the quantitative determination of wine components, an international collaborative trial was organized to evaluate the method according to the international regulations and guidelines of the German Institute for Standardization/International Organization for Standardization, AOAC INTERNATIONAL, the International Union of Pure and Applied Chemistry, and the International Organization of Vine and Wine. Sugars such as glucose; acids such as malic, acetic, fumaric, and shikimic acids (the latter two as minor components); and sorbic acid, a preservative, were selected for the exemplary quantitative determination of substances in wine. Selection criteria for the examination of sample material included different NMR spectral signal types (singlet and multiplet), as well as the suitability of the proposed substances for manual integration at different levels of challenge (e.g., interference as a result of the necessary suppression of a water signal or the coverage of different typical wine concentration ranges for a selection of major components, minor components, and additives). To show that this method can be universally applied, NMR measurement and the method of evaluation were not strictly elucidated. Fifteen international laboratories participated in the collaborative trial and determined six parameters in 10 samples. The values, in particular the reproducibility SD (SR), were compared with the expected Horwitz SD (SH) by forming the quotient SR/SH (i.e., the HorRat value). The resulting HorRat values of most parameters were predominantly between 0.6 and 1.5, and thus of an acceptable range.

Older people often consult primary care physicians about back pain, with many also receiving concurrent care from complementary and alternative medicine providers, most commonly doctors of chiropractic. However, a collaborative model of treatment coordination between these two provider groups has yet to be tested. The primary aim of the Collaborative Care for Older Adults Clinical Trial is to develop and evaluate the clinical effectiveness and feasibility of a patient-centered, collaborative care model with family medicine physicians and doctors of chiropractic for the treatment of low back pain in older adults. Methods/design This pragmatic, pilot randomized controlled trial will enroll 120 participants, age 65 years or older with subacute or chronic low back pain lasting at least one month, from a community-based sample in the Quad-Cities, Iowa/Illinois, USA. Eligible participants are allocated in a 1:1:1 ratio to receive 12 weeks of medical care, concurrent medical and chiropractic care, or collaborative medical and chiropractic care. Primary outcomes are self-rated back pain and disability. Secondary outcomes include general and functional health status, symptom bothersomeness, expectations for treatment effectiveness and improvement, fear avoidance behaviors, depression, anxiety, satisfaction, medication use and health care utilization. Treatment safety and adverse events also are monitored. Participant-rated outcome measures are collected via self-reported questionnaires and computer-assisted telephone interviews at baseline, and at 4, 8, 12, 24, 36 and 52 weeks post-randomization. Provider-rated expectations for treatment effectiveness and participant improvement also are evaluated. Process outcomes are assessed through qualitative interviews with study participants and research clinicians, chart audits

    The repeated-dose liver micronucleus (RDLMN) assay using young adult rats has the potential to detect hepatocarcinogens. We conducted a collaborative study to assess the performance of this assay and to evaluate the possibility of integrating it into general toxicological studies. Twenty-four testing laboratories belonging to the Mammalian Mutagenicity Study Group, a subgroup of the Japanese Environmental Mutagen Society, participated in this trial. Twenty-two model chemicals, including some hepatocarcinogens, were tested in 14- and/or 28-day RDLMN assays. As a result, 14 out of the 16 hepatocarcinogens were positive, including 9 genotoxic hepatocarcinogens, which were reported negative in the bone marrow/peripheral blood micronucleus (MN) assay by a single treatment. These outcomes show the high sensitivity of the RDLMN assay to hepatocarcinogens. Regarding the specificity, 4 out of the 6 non-liver targeted genotoxic carcinogens gave negative responses. This shows the high organ specificity of the RDLMN assay. In addition to the RDLMN assay, we simultaneously conducted gastrointestinal tract MN assays using 6 of the above carcinogens as an optional trial of the collaborative study. The MN assay using the glandular stomach, which is the first contact site of the test chemical when administered by oral gavage, was able to detect chromosomal aberrations with 3 test chemicals including a stomach-targeted carcinogen. The treatment regime was the 14- and/or 28-day repeated-dose, and the regime is sufficiently promising to incorporate these methods into repeated-dose toxicological studies. The outcomes of our collaborative study indicated that the new techniques to detect chromosomal aberrations in vivo in several tissues worked successfully.

    Full Text Available Abstract Background Large clinical trials databases, developed over the course of a comprehensive clinical trial programme, represent an invaluable resource for clinical researchers. Data mining projects sponsored by industry that use these databases, however, are often not viewed favourably in the academic medical community because of concerns that commercial, rather than scientific, goals are the primary purpose of such endeavours. Thus, there are few examples of sustained collaboration between leading academic clinical researchers and industry professionals in a large-scale data mining project. We present here a successful example of this type of collaboration in the field of dementia. Methods The Donepezil Data Repository comprised 18 randomised, controlled trials conducted between 1991 and 2005. The project team at Pfizer determined that the data mining process should be guided by a diverse group of leading Alzheimer's disease clinical researchers called the "Expert Working Group." After development of a list of potential faculty members, invitations were extended and a group of seven members was assembled. The Working Group met regularly with Eisai/Pfizer clinicians and statisticians to discuss the data, identify issues that were currently of interest in the academic and clinical communities that might lend themselves to investigation using these data, and note gaps in understanding or knowledge of Alzheimer's disease that these data could address. Leadership was provided by the Pfizer Clinical Development team leader; Working Group members rotated responsibility for being lead and co-lead for each investigation and resultant publication. Results Six manuscripts, each published in a leading subspecialty journal, resulted from the group's work. Another project resulted in poster presentations at international congresses and two were cancelled due to resource constraints. Conclusions The experience represents a particular approach to

    AOAC First Action Method 2011.18, Myo-Inositol (Free and Bound as Phosphatidylinositol) in Infant and Pediatric Formulas and Adult Nutritionals, was collaboratively studied. With this method free myo-inositol and phosphatidylinositol bound myo-inositol are extracted using two different sample preparation procedures, separated by ion chromatography using a combination of Dionex Carbo Pac PA1 and MA1 columns with column switching, and detected with pulsed amperometry using a gold electrode. Free myo-inositol is extracted from samples with dilute hydrochloric acid and water. Phosphatidylinositol is extracted from samples with chloroform and separated from other fats with silica SPE cartridges. Myo-inositol is then released from the glycerol backbone with concentrated acetic and hydrochloric acids at 120°C. During this collaborative study, nine laboratories from five different countries analyzed blind duplicates of nine infant and pediatric nutritional formulas for both free and phosphatidylinositol bound myo-inositol, and one additional laboratory only completed the free myo-inositol analyses. The method demonstrated acceptable repeatability and reproducibility and met the AOAC Stakeholder Panel on Infant Formula and Adult Nutritionals (SPIFAN) Standard Method Performance Requirements (SMPRs®) for free myo-inositol plus phosphatidylinositol bound myo-inositol for all the matrixes analyzed. SMPRs for repeatability were ≤5% RSD at myo-inositol concentrations of 2-68 mg/100 g ready-to-feed (RTF) liquid. SMPRs for reproducibility were ≤8% RSD in products with myo-inositol concentrations ranging from 2 to 68 mg/100 g RTF liquid. During this collaborative study, repeatability RSDs ranged from 0.51 to 3.22%, and RSDs ranged from 2.66 to 7.55% for free myo-inositol plus phosphatidylinositol bound myo-inositol.

    The preliminary results of an international collaborative study examining premature menopause in fragile X carriers are presented. A total of 760 women from fragile X families was surveyed about their fragile X carrier status and their menstrual and reproductive histories. Among the subjects, 395 carried a premutation, 128 carried a full mutation, and 237 were noncarriers. Sixty-three (16%) of the premutation carriers had experienced menopause prior to the age of 40 compared with none of the full mutation carriers and one (0.4%) of the controls. Based on these preliminary data, there is a significant association between fragile X premutation carrier status and premature menopause.

    The official AOAC manual Kjeldahl method for determining crude protein in animal feeds, 7.015, uses HgO as a catalyst in the digestion step. Because of environmental considerations, there is considerable interest in alternative catalysts. A collaborative study compares the official HgO-catalyzed method and an alternative using CuSO4. Fifty-four samples consisting of blind duplicates of closely matched pairs, representing a range of animal feed materials and 2 standard materials, were analyzed once by each method. Results were returned by 22 laboratories. Means and standard deviations between methods were comparable. The CuSO4-catalyzed method has been adopted official first action.

    Science is increasingly dominated by teams. Understanding patterns of scientific collaboration and their impacts on the productivity and evolution of disciplines is crucial to understand scientific processes. Electronic bibliography offers a unique opportunity to map and investigate the nature of scientific collaboration. Recent studies have demonstrated a counterintuitive organizational pattern of scientific collaboration networks: densely interconnected local clusters consist of weak ties, whereas strong ties play the role of connecting different clusters. This pattern contrasts itself from many other types of networks where strong ties form communities while weak ties connect different communities. Although there are many models for collaboration networks, no model reproduces this pattern. In this paper, we present an evolution model of collaboration networks, which reproduces many properties of real-world collaboration networks, including the organization of tie strengths, skewed degree and weight distribution, high clustering, and assortative mixing.
