Blaine, M

2000-01-01

Home attendants (HAs) work in relative isolation, burdened by conflicting demands. This article details an eight-session support group for HAs, designed to explore its effects on their work life. Meeting for hour-and-a-half sessions with no fixed agenda, the group offered members an opportunity to communicate with others in similar situations. Participants reported that the group experience helped relieve stress and made them feel less alone. Other benefits included gaining strategies for coping with difficult situations and learning to set boundaries. Further investigation into the effectiveness of similar groups is suggested.

Genomic research projects that collect tissues from deceased organ and tissue donors must obtain the authorization of family decision makers under difficult circumstances that may affect the authorization process. Using a quasi-experimental design, the Ethical, Legal, and Social Issues (ELSI) substudy of the Genotype-Tissue Expression (GTEx) project compared the recall and understanding of the donation authorization process of two groups: family members who had authorized donation of tissues to the GTEx project (the comparison group) and family members who had authorized organ and tissue donations in years previous, who subsequently participated in two different mock-authorization processes that mimicked the GTEx authorization process (the intervention groups). Participants in the comparison and intervention groups were matched on key demographic characteristics. We found that participants in the intervention groups who experienced a mock-authorization process demonstrated better recall of the tissue donation request than members of the comparison group. Our data indicate that the stress associated with the loss of a loved one limited the ability of family members to recall details about the GTEx project. However, we found a similar lack of knowledge in both the comparison and the intervention group participants, suggesting lack of knowledge may be due to the complexity and unfamiliarity of the information presented to them during the authorization process. We discuss these findings in the context of everyday clinical decision making in cognitively challenging conditions. Copyright 2018 The Journal of Clinical Ethics. All rights reserved.

Spatial Collective Intelligence? credibility, accuracy, and Volunteered Geographic Information

PubMed Central

Spielman, Seth E.

2014-01-01

Collective intelligence is the idea that under the right circumstances collections of individuals are smarter than even the smartest individuals in the group (Suroweiki 2004), that is a group has an “intelligence” that is independent of the intelligence of its members. The ideology of collective intelligence undergirds much of the enthusiasm about the use of “volunteered” or crowdsourced geographic information. Literature from a variety of fields makes clear that not all groups possess collective intelligence, this paper identifies four pre-conditions for the emergence of collective intelligence and then examine the extent to which collectively generated mapping systems satisfy these conditions. However, the “intelligence” collectively generated maps is hard to assess because there are two difficult to reconcile perspectives on map quality- the credibility perspective and the accuracy perspective. Much of the current literature on user generated maps focuses on assessing the quality of individual contributions. However, because user generated maps are complex social systems and because the quality of a contribution is difficult to assess this strategy may not yield an “intelligent” end product. The existing literature on collective intelligence suggests that the structure of groups more important that the intelligence of group members. Applying this idea to user generated suggests that systems should be designed to foster conditions known to produce collective intelligence rather than privileging particular contributions/contributors. The paper concludes with some design recommendations and by considering the implications of collectively generated maps for both expert knowledge and traditional state sponsored mapping programs.

Use of the internet to study the utility values of the public.

One of the most difficult tasks in cost-effectiveness analysis is the measurement of quality weights (utilities) for health states. The task is difficult because subjects often lack familiarity with health states they are asked to rate and because utilities measures such as the standard gamble, ask subjects to perform tasks that are complex and far from everyday experience. A large body of research suggests that computer methods can play an important role in explaining health states and measuring utilities. However, administering computer surveys to a "general public" sample, the most relevant sample for cost-effectiveness analysis, is logistically difficult. In this paper, we describe a software system designed to allow the study of general population preferences in a volunteer Internet survey panel. The approach, which relied on over sampling of ethnic groups and older members of the panel, produced a data set with an ethnically, chronologically and geographically diverse group of respondents, but was not successful in replicating the joint distribution of demographic patterns in the population.

mcrA-Targeted Real-Time Quantitative PCR Method To Examine Methanogen Communities▿

PubMed Central

Steinberg, Lisa M.; Regan, John M.

2009-01-01

Methanogens are of great importance in carbon cycling and alternative energy production, but quantitation with culture-based methods is time-consuming and biased against methanogen groups that are difficult to cultivate in a laboratory. For these reasons, methanogens are typically studied through culture-independent molecular techniques. We developed a SYBR green I quantitative PCR (qPCR) assay to quantify total numbers of methyl coenzyme M reductase α-subunit (mcrA) genes. TaqMan probes were also designed to target nine different phylogenetic groups of methanogens in qPCR assays. Total mcrA and mcrA levels of different methanogen phylogenetic groups were determined from six samples: four samples from anaerobic digesters used to treat either primarily cow or pig manure and two aliquots from an acidic peat sample stored at 4°C or 20°C. Only members of the Methanosaetaceae, Methanosarcina, Methanobacteriaceae, and Methanocorpusculaceae and Fen cluster were detected in the environmental samples. The three samples obtained from cow manure digesters were dominated by members of the genus Methanosarcina, whereas the sample from the pig manure digester contained detectable levels of only members of the Methanobacteriaceae. The acidic peat samples were dominated by both Methanosarcina spp. and members of the Fen cluster. In two of the manure digester samples only one methanogen group was detected, but in both of the acidic peat samples and two of the manure digester samples, multiple methanogen groups were detected. The TaqMan qPCR assays were successfully able to determine the environmental abundance of different phylogenetic groups of methanogens, including several groups with few or no cultivated members.

Reframing Balint: thoughts on family medicine departmental Balint groups.

Stein, Howard F

2003-04-01

This paper explores recurrent processes and themes in the 1,300 family medicine faculty, resident, intern, and community Balint groups the author has facilitated/led. The frequent group "deviation" from the central Balint task of understanding difficult physician-patient relationships is reframed as less "resistance" or "obstacle" to work, as it is an expression of unmet developmental needs and organizational realities. When group members are carefully attended to (by facilitator and one another), the group often becomes emotionally capable of addressing a "case " in the conventional Balint understanding of the work the group has assembled to do. The group dynamics of such "hybrid" Balint groups thus become comprehensible as other than error.

This project is currently under contract for research through the Department of Homeland Security until 2011. The group I was responsible for studying has to remain confidential so as not to affect the current project. All dates, reference links and authors, and other distinguishing characteristics of the original group have been removed from this report. All references to the name of this group or the individual splinter groups has been changed to 'Group X'. I have been collecting texts from a variety of sources intended for the use of recruiting and radicalizing members for Group X splinter groups for themore » purpose of researching the motivation and intent of leaders of those groups and their influence over the likelihood of group radicalization. This work included visiting many Group X websites to find information on splinter group leaders and finding their statements to new and old members. This proved difficult because the splinter groups of Group X are united in beliefs, but differ in public opinion. They are eager to tear each other down, prove their superiority, and yet remain anonymous. After a few weeks of intense searching, a list of eight recruiting texts and eight radicalizing texts from a variety of Group X leaders were compiled.« less

Perceived discontinuities and continuities in transdisciplinary scientific working groups.

We examine the DataONE (Data Observation Network for Earth) project, a transdisciplinary organization tasked with creating a cyberinfrastructure platform to ensure preservation of and access to environmental science and biological science data. Its objective was a difficult one to achieve, requiring innovative solutions. The DataONE project used a working group structure to organize its members. We use organizational discontinuity theory as our lens to understand the factors associated with success in such projects. Based on quantitative and qualitative data collected from DataONE members, we offer recommendations for the use of working groups in transdisciplinary synthesis. Recommendations include welcome diverse opinions and world views, establish shared communication practices, schedule periodic synchronous face-to-face meetings, and ensure the active participation of bridge builders or knowledge brokers such as librarians who know how to ask questions about disciplines not their own.

2017-04-28

Despite growing evidence of the benefits of including assessment for learning strategies within programmes of assessment, practical implementation of these approaches is often problematical. Organisational culture change is often hindered by personal and collective beliefs which encourage adherence to the existing organisational paradigm. We aimed to explore how these beliefs influenced proposals to redesign a summative assessment culture in order to improve students' use of assessment-related feedback. Using the principles of participatory design, a mixed group comprising medical students, clinical teachers and senior faculty members was challenged to develop radical solutions to improve the use of post-assessment feedback. Follow-up interviews were conducted with individual members of the group to explore their personal beliefs about the proposed redesign. Data were analysed using a socio-cultural lens. Proposed changes were dominated by a shared belief in the primacy of the summative assessment paradigm, which prevented radical redesign solutions from being accepted by group members. Participants' prior assessment experiences strongly influenced proposals for change. As participants had largely only experienced a summative assessment culture, they found it difficult to conceptualise radical change in the assessment culture. Although all group members participated, students were less successful at persuading the group to adopt their ideas. Faculty members and clinical teachers often used indirect techniques to close down discussions. The strength of individual beliefs became more apparent in the follow-up interviews. Naïve epistemologies and prior personal experiences were influential in the assessment redesign but were usually not expressed explicitly in a group setting, perhaps because of cultural conventions of politeness. In order to successfully implement a change in assessment culture, firmly-held intuitive beliefs about summative assessment will need to be clearly understood as a first step.

The sentinel behaviour of Arabian babbler floaters

2017-01-01

The sentinel behaviour of 38 Arabian babbler adult floaters, who lived alone within a territory belonging to a foreign group, was studied and compared with their own sentinel behaviour in the past, when they were group members. All floaters acted as sentinels and uttered ‘alarm calls’. This suggests that sentinel activity is due at least, in part, to selfish motives. Floaters sentinelled less than they did as group members, with the decrease in sentinel activity sharper for ex-dominants than for ex-subordinates. One possible explanation for these differences is that sentinel activity is aimed not only at detecting predators, but also at detecting foreign conspecifics. Within a group, the latter incentive is stronger for breeding dominants than for subordinates, whereas all floaters alike may be trying to detect the owners of the territory in which they were roaming but also to avoid being detected by them. Other possible explanations are that floaters have less time and energy for sentinel activity because they are weaker or because foraging is more difficult in a foreign territory. This may be especially so for dominants who used to enjoy privileged access to food in their group. No significant difference was found in the rate of sentinels' ‘alarm calls’ between floaters and group members, suggesting that their main purpose is predator–prey communication, of which warning groupmates may be a side benefit.

Patient and public involvement (PPI) is increasingly recognised as important in research. Most PPI takes place face-to-face, but this can be difficult for people who are unwell or have caring responsibilities. As these challenges are particularly common in palliative care and rehabilitation research, we developed an online forum for PPI: www.csipublicinvolvement.co.uk. In this study, we explored how well the online forum worked, if it is a suitable method for PPI, and how PPI members and researchers reacted to using it. We used an existing theory about online interventions to help choose the 'right' questions to ask participants. We invited PPI members and researchers who had used the online forum to participate in focus groups, and identified the most important themes discussed. Within this study, PPI members have helped with the interview questions, analysis, and write up. Overall, four PPI members and five researchers participated in the focus groups. Participants felt the online forum worked well and had multiple benefits. From the discussions, we identified four key questions to consider when developing online methods for PPI: how does the forum work, how does it engage people, how does it empower people, and what is the impact? Participants suggested the forum could be improved by being more PPI and less researcher focused. We conclude that when developing online methods of PPI, a functioning forum is not enough: it also needs to be engaging and empowering to have an impact. Future work can use these four domains when developing their own online PPI methods. Patient and public involvement (PPI) in research is increasingly recognised as important. Most PPI activities take place face-to-face, yet this can be difficult for people with ill health or caring responsibilities, and may exclude people from hard-to-reach populations (e.g. living in vulnerable social circumstances and/or remote geographical locations). These challenges are particularly pertinent in palliative care and rehabilitation research where people often live with, or care for someone with, advanced illness. In response to this, we aimed to test the functionality, feasibility, and acceptability of an online forum for PPI for palliative care and rehabilitation research (www.csipublicinvolvement.co.uk). We conducted separate focus groups with PPI members and researchers who had used the online forum. Data collection was underpinned by DeLone and Mclean's model of information systems success. Focus groups were recorded, transcribed, and analysed using inductive thematic analysis. Dual coding by two authors ensured rigour, and attention was paid to divergent cases. Four PPI members and five researchers participated in the focus groups (two PPI focus groups, one researcher focus group). The online forum was perceived as functional, feasible, and acceptable. Our analysis identified four key questions to consider when developing online methods for PPI: (1) how does the forum work, (2) how does it engage people, (3) how does it empower people, and (4) what is the impact? PPI members felt that the online forum was too researcher led, and needed to be more PPI focussed. When developing online methods of PPI, a functioning forum is not enough: it also needs to be engaging and empowering to have an impact. To optimise online involvement, future work should refer to these four domains and balance the needs of researchers and PPI members.

Indications of Recruitment Challenges in Research with U.S. Military Service Members: A ClinicalTrials.gov Review.

2017-03-01

The success of military-relevant health research often depends on recruiting adequate numbers of U.S. military service members as research participants. Researchers have reported difficulties in recruiting service member research participants. Reviews of ClinicalTrials.gov, an online clinical trial registry of publicly and privately sponsored studies, have identified challenges in participant recruitment and barriers to study completion in various research populations. The purpose of this study was to identify indications of difficulty recruiting U.S. military service members as research participants based on data from study records in ClinicalTrials.gov. Records of studies starting between 2005 and 2014 were collected from ClinicalTrials.gov and updated through January 2016. Three hundred and two studies that included ≥25% U.S. military service member research participants were (1) compared to a comparison group of 302 studies, each with <5% service member participants and (2) compared by the proportion of service member participants within studies in the military group ("many" ≥25% but <100% service members and "all" 100% service members). Groups were evaluated and compared for recruitment status; reasons for study withdrawal, termination, or suspension; achievement of ≥85% of the anticipated enrollment; and differences in achieving recruitment goals according to study sponsor. Twelve percent of studies in the military group had been withdrawn, terminated, or suspended; enrollment and funding problems were the most common reasons. The comparison group had 11% of studies withdrawn, terminated, or suspended; the most common reasons were enrollment problems and sponsor decision. All study groups had indications of difficulty adequately achieving participant enrollment goals. Among studies with known anticipated and actual enrollment, approximately half in both the military group (47.9%) and comparison group (50.3%) achieved ≥85% of the anticipated enrollment (p = 0.722). Half of studies with many service members and 44% of studies with all service members achieved ≥85% of the anticipated enrollment (p = 0.600). In comparing the many and all service member subgroups, significant differences were found in the median values for anticipated enrollment and actual enrollment, even when accounting for Bonferroni correction. Evaluations of mean values did not show a statistical difference between the military subgroups. There were no significant differences according to study sponsor (military, academic, Veterans Affairs, National Institutes of Health, nonprofit organization, or industry) for a study achieving or not achieving ≥85% of the anticipated enrollment. This review supports anecdotal reports of difficulty recruiting service members as research participants. However, the findings also indicate that in many regards, there is not much difference in the difficulties recruiting service members versus other research participants. Findings suggest that it is often difficult to recruit research participants regardless of the specific population or type of study sponsor, and that studies with either many or all service member participants have similar achievement of recruitment goals. Findings in this study may be useful for those who design research that includes service members or for those who are apprehensive about including service members in their research.

Phinney, J S

1990-11-01

Ethnic identity is central to the psychological functioning of members of ethnic and racial minority groups, but research on the topic is fragmentary and inconclusive. This article is a review of 70 studies of ethnic identity published in refereed journals since 1972. The author discusses the ways in which ethnic identity has been defined and conceptualized, the components that have been measured, and empirical findings. The task of understanding ethnic identity is complicated because the uniqueness that distinguishes each group makes it difficult to draw general conclusions. A focus on the common elements that apply across groups could lead to a better understanding of ethnic identity.

In Tanzania, the international microfinance network FINCA set up shop and began training its first Village Banking Groups in June 1998, disbursing its first loans in July with a grant from the US Agency for International Development. Within 2 months, the program reached 757 low-income women and distributed loans worth US$57,183 using the group support system in which 30-50 neighbors come together to guarantee one another's loans. With the loans from FINCA, entrepreneurs quickly became involved in a range of business activities, from selling tomatoes to starting a hair salon. Located in Mwanza, in the Lake Zone, FINCA Tanzania's clients include many members of the Sukuma tribe. It is noted that in this region there are a few job opportunities in the formal economy. In 1999, FINCA Tanzania reached 3632 clients, exceeding its targets despite a difficult economic environment. In that same year, FINCA partnered with Freedom from Hunger in launching a program that offers some of its members health education and basic business training at Village Banking Group meetings.

To empirically define the concept of burden of neck pain. The lack of a clear understanding of this construct from the perspective of persons with neck pain and care providers hampers adequate measurement of this burden. An additional aim was to compare the conceptual model obtained with the frequently used Neck Disability Index (NDI). Concept mapping, combining qualitative (nominal group technique and group consensus) and quantitative research methods (cluster analysis and multidimensional scaling), was applied to groups of persons with neck pain (n = 3) and professionals treating persons with neck pain (n = 2). Group members generated statements, which were organized into concept maps. Group members achieved consensus about the number and description of domains and the researchers then generated an overall mind map covering the full breadth of the burden of neck pain. Concept mapping revealed 12 domains of burden of neck pain: impaired mobility neck, neck pain, fatigue/concentration, physical complaints, psychological aspects/consequences, activities of daily living, social participation, financial consequences, difficult to treat/difficult to diagnose, difference of opinion with care providers, incomprehension by social environment, and how person with neck pain deal with complaints. All ten items of the NDI could be linked to the mind map, but the NDI measures only part of the burden of neck pain. This study revealed the relevant domains for the burden of neck pain from the viewpoints of persons with neck pain and their care providers. These results can guide the identification of existing measurements instruments for each domain or the development of new ones to measure the burden of neck pain.

VisEL: Visualisation of Expertise Level in a Special Interest Group Knowledge Portal

Zulhafizsyam Wan Ahmad, Wan Muhammad; Sulaiman, Shahida; Yusof, Umi Kalsom

A variety of portals are available nowadays to support diverse purposes such as commercial, publishing, personal, affinity and corporate portals. Affinity portals promote electronic communities who share common interest such as a special interest group (SIG). Knowledge portal is an emerging trend that benefits the existing portal technology by designing such portals with proper representation of the members' shared knowledge. Besides textual representation for diverse expertise levels, graphical visualisation will be able to support the requirements in searching and representing expertise level among e-community. There is a number of existing SIG portals available. However, they do not visualise effectively and accurately the expertise level of members and make it difficult for users to search their targeted experts for instance searching the highest expertise level to have a discussion and to solve their problems related to a project. The goal of this paper is to propose a graphical visualisation of expertise level method (VisEL) using an interactive tag cloud technique that represents expertise level of each member based on their knowledge in a software engineering SIG portal.

Membership in formal or informal groups of students with similar interests provides many benefits to undergraduate astronomy majors at the University of Arizona. First and foremost, members benefit from peer social and academic support within the major. These benefits are both tangible and intangible: students form friendships with like-minded peers, which can sustain them through difficult periods of study, but these social networks are the basis of later professional networks as well. Students in the U of A Astronomy Club have received both informal and formal research positions at other institutions as a direct result of the support, peer mentoring, and connections of club members, and at least six also hold paid, non-research positions within the department as a result of their connection to the club. Finally, most Astronomy Club members take their first steps into professional astronomy, such as attendance at a AAS Meeting, as a result of Club membership and the encouragement of older club members.

Population densities of indigenous Acidobacteria change in the presence of plant growth promoting rhizobacteria (PGPR) in rhizosphere.

Rhizosphere microbial community has diverse metabolic capabilities and plays a crucial role in maintaining plant health. Oligotrophic plant growth promoting rhizobacteria (PGPR), along with difficult-to-culture microbial fractions, might be involved synergistically in microbe-microbe and plant-microbe interactions in the rhizosphere. Among the difficult-to-culture microbial fractions, Acidobacteria constitutes the most dominant phylum thriving in rhizospheric soils. We selected effective PGPR for tomato and black gram and studied their effect on population densities of acidobacterial members. Three facultatively oligotrophic PGPR were identified through 16S rRNA gene sequencing as Sphingobacterium sp. (P3), Variovorax sp. (P4), and Roseomonas sp. (A2); the latter being a new report of PGPR. In presence of selected PGPR strains, the changes in population densities of Acidobacteria were monitored in metagenomic DNA extracted from bulk and rhizospheric soils of tomato and black gram using real time qPCR. A gradual increase in equivalent cell numbers of Acidobacteria members was observed over time along with a simultaneous increase in plant growth promotion by test PGPR. We report characterization of three effective PGPR strains and their effects on indigenous, underexplored difficult-to-culture phylum-Acidobacteria. We suggest that putative interactions between these two bacterial groups thriving in rhizospheric soils could be beneficial for plant growth. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Writing for publication, in the nursing profession, is considered essential for the development of the profession and individual career advancement. In education there is also the increasing pressure to produce University research output. To develop a collaborative writing group to develop and write articles relating to our teaching practice. The idea of forming a writing group was discussed at a module team meeting where five academics expressed an interest. The process of forming the group involved an initial meeting to discuss and agree to the aims, interests, expertise and areas of responsibility for each member. Regular meetings are held and each member takes on responsibility for an aspect of work towards completing the articles. Three articles and one editorial have been published and another is under peer review. We have endeavoured to develop and maintain a theme, this being supporting nursing students' development with an emphasis on an aspect of their decision making skills. Also, importantly, we have created a supportive environment and friendships. The demands made upon the nurse educator to be clinically, educationally and research active can be difficult to meet. Collaborative writing groups may be one way to fulfil the scholarly activity element. Copyright © 2013 Elsevier Ltd. All rights reserved.

Physical exercise confers many health benefits, but it is difficult to motivate people to exercise. Although community exercise groups may facilitate initiation and persistence in an exercise program, reports regarding factors that allow such groups to flourish are limited. We performed a prospective qualitative evaluation of our experience starting a program of community-based, peer-led exercise groups for military veterans to identify important lessons learned. We synthesized data from structured observations, post-observation debriefings, and focus groups. Our participants were trained peer leaders and exercise group members. Our main outcomes consisted of empirically derived lessons learned during the implementation of a peer-led group exercise program for veterans at multiple community sites. We collected and analyzed data from 40 observation visits (covering 14 sites), 7 transcribed debriefings, and 5 focus groups. We identified five lessons learned. (1) The camaraderie and social aspect of the exercise groups provided motivation for people to stay involved. (2) Shared responsibility and commitment to each other by the group members was instrumental to success. (3) Regular meeting times encouraged participation. (4) Variety, especially getting outdoors, was very popular for some groups. (5) Modest involvement of professionals encouraged ongoing engagement with the program. Both social and programmatic issues influence implementation of group exercise programs for older, predominantly male, veterans. These results should be confirmed in other settings.

Social dominance orientation, nonnative accents, and hiring recommendations.

PubMed

Hansen, Karolina; Dovidio, John F

2016-10-01

Discrimination against nonnative speakers is widespread and largely socially acceptable. Nonnative speakers are evaluated negatively because accent is a sign that they belong to an outgroup and because understanding their speech requires unusual effort from listeners. The present research investigated intergroup bias, based on stronger support for hierarchical relations between groups (social dominance orientation [SDO]), as a predictor of hiring recommendations of nonnative speakers. In an online experiment using an adaptation of the thin-slices methodology, 65 U.S. adults (54% women; 80% White; Mage = 35.91, range = 18-67) heard a recording of a job applicant speaking with an Asian (Mandarin Chinese) or a Latino (Spanish) accent. Participants indicated how likely they would be to recommend hiring the speaker, answered questions about the text, and indicated how difficult it was to understand the applicant. Independent of objective comprehension, participants high in SDO reported that it was more difficult to understand a Latino speaker than an Asian speaker. SDO predicted hiring recommendations of the speakers, but this relationship was mediated by the perception that nonnative speakers were difficult to understand. This effect was stronger for speakers from lower status groups (Latinos relative to Asians) and was not related to objective comprehension. These findings suggest a cycle of prejudice toward nonnative speakers: Not only do perceptions of difficulty in understanding cause prejudice toward them, but also prejudice toward low-status groups can lead to perceived difficulty in understanding members of these groups.

Perception of stress, control, and satisfaction was measured by office managers in medical practices. Office managers spend enormous amounts of time each day handling difficult interpersonal issues among staff physicians, and patients. As a group, physician disruptions were the most prevalent per day. Other staff members were considered the most stressful by rank order. Significant differences were discovered between primary care practices versus specialty practices in the areas of interactions with physicians.

Background Minority groups are underrepresented in research, making it difficult to apply medical advances with confidence. In this study, we explored whether community-based cancer education sites and educators serving the African American community could be used to recruit minority participants to research. Methods We invited Individuals at community education sites to provide buccal scrapings, saliva samples, psychometric data, and personal information anonymously. Results Culturally aligned community sites (100%) collaborated in the research recruitment, as did 83% of the individuals at those sites. Conclusion Community-based education sites offer exceptional promise for teaching about research benefits and recruiting members of minority groups to research studies. PMID:16497136

ME (Myalgic Encephalomyelitis) or CFS (chronic fatigue syndrome) is a debilitating illness for which no cause or medical tests have been identified. Debates over its nature have generated interest from qualitative researchers. However, participants are difficult to recruit because of the nature of their condition. Therefore, this study explores the utility of the internet as a means of eliciting accounts. We analyse data from focus groups and the internet in order to ascertain the extent to which previous research findings apply to the internet domain. Interviews were conducted among 49 members of internet groups (38 chatline, 11 personal) and 7 members of two face-to-face support groups. Discourse analysis of descriptions and accounts of ME or CFS revealed similar devices and interactional concerns in both internet and face-to-face communication. Participants constructed their condition as serious, enigmatic and not psychological. These functioned to deflect problematic assumptions about ME or CFS and to manage their accountability for the illness and its effects.

Integrative taxonomy of the fly orchid group: insights from chemical ecology

Several authors have recently stressed the need to develop an integrative approach in taxonomy, but studies applying such an approach to Mediterranean orchids are scarce. In sexually deceptive orchids from the taxonomically difficult genus Ophrys, pollination is specific and performed by male insects attracted to the flowers by sex pheromone-mimicking floral scents. Floral compounds are therefore of primary importance for reproductive isolation and species delimitations in this genus. In the fly orchid group, molecular, morphological, and ecological characters have been extensively studied, but a comprehensive survey of floral scents is still lacking. In the present study, the blends of floral compounds of its three members, Ophrys insectifera, Ophrys aymoninii, and Ophrys subinsectifera, were extracted and analyzed by gas chromatography-mass spectrometry. A total of 107 compounds were found, with a majority of saturated and unsaturated hydrocarbons. Significant differentiation, both qualitative and quantitative, was found among the three taxa. This result, pooled with those from the literature, forms a comprehensive and congruent dataset that allows us to elucidate the taxonomic rank of the three members of the fly orchid group.

Half of a $10,000 grant was given by the International Planned Parenthood Federation (IPPF) to finance the rural development project activities of Danfa, a village of about 835 people in Ghana. In this community the women are hard working but doubly disadvantaged. Along with a high illiteracy rate, the women are limited by inadequate income due to underemployment, under productivity, unfavorable farming conditions, and a lack of resources. Large families, frequent pregnancies, poor mother and child health, and high infant mortality all make matters worse for both the rural farm wife and her family. The project began with a nucleus of women that soon grew to between 24-30. Members soon formed small groups according to their occupational interests. The women grasped the self-help idea immediately. Once or twice a month there were demonstrations and the group worked together in such activities as making soap and pomade, preparing meals, and sewing. Meetings generally ended with a general group brainstorming and then members gathered in smaller groups to review their activities and plan for the future. During the 1st year of the project the men in the group rarely attended meetings. The group gave priority attention to their community's urgent need for working capital. 15 women farmers who met the criteria determined by the group received loans in the 1st round; only 8 satisfied the criteria in the 2nd round. At the beginning of the small loans scheme, the group decided to seek bigger loans from the bank if members proved credit worthy. This requirement was satisfied, and the group began negotiations for a loan with the Agricultural Development Bank. The group received the total group loan. The Ghana Home Science Association considers the project to be successful in several respects. Team spirit has developed the group, and the women play important and respected roles. Family planning problems are regularly presented for discussion, but it is difficult to correlate these ideas with practice. The ability of members to discuss these problems comfortably is an indication of their acceptance of family planning as an important topic in their lives.

Financial abuse of older people by a family member: a difficult terrain for service providers in Australia.

Financial abuse by a family member is the most common form of abuse experienced by older Australians, and early intervention is required. National online surveys of 228 chief executive officers and 214 aged care service providers found that, while they were well placed to recognize financial abuse, it was often difficult to intervene successfully. Problems providers encountered included difficulties in detecting abuse, the need for consent before they could take action, the risk that the abusive family member would withdraw the client from the service, and a lack of resources to deal with the complexities inherent in situations of financial abuse.

VMCast: A VM-Assisted Stability Enhancing Solution for Tree-Based Overlay Multicast.

Tree-based overlay multicast is an effective group communication method for media streaming applications. However, a group member's departure causes all of its descendants to be disconnected from the multicast tree for some time, which results in poor performance. The above problem is difficult to be addressed because overlay multicast tree is intrinsically instable. In this paper, we proposed a novel stability enhancing solution, VMCast, for tree-based overlay multicast. This solution uses two types of on-demand cloud virtual machines (VMs), i.e., multicast VMs (MVMs) and compensation VMs (CVMs). MVMs are used to disseminate the multicast data, whereas CVMs are used to offer streaming compensation. The used VMs in the same cloud datacenter constitute a VM cluster. Each VM cluster is responsible for a service domain (VMSD), and each group member belongs to a specific VMSD. The data source delivers the multicast data to MVMs through a reliable path, and MVMs further disseminate the data to group members along domain overlay multicast trees. The above approach structurally improves the stability of the overlay multicast tree. We further utilized CVM-based streaming compensation to enhance the stability of the data distribution in the VMSDs. VMCast can be used as an extension to existing tree-based overlay multicast solutions, to provide better services for media streaming applications. We applied VMCast to two application instances (i.e., HMTP and HCcast). The results show that it can obviously enhance the stability of the data distribution.

A Subset of Ubiquitin-Conjugating Enzymes Is Essential for Plant Immunity1[OPEN

Connor, Richard A.

2017-01-01

Of the three classes of enzymes involved in ubiquitination, ubiquitin-conjugating enzymes (E2) have been often incorrectly considered to play merely an auxiliary role in the process, and few E2 enzymes have been investigated in plants. To reveal the role of E2 in plant innate immunity, we identified and cloned 40 tomato genes encoding ubiquitin E2 proteins. Thioester assays indicated that the majority of the genes encode enzymatically active E2. Phylogenetic analysis classified the 40 tomato E2 enzymes into 13 groups, of which members of group III were found to interact and act specifically with AvrPtoB, a Pseudomonas syringae pv tomato effector that uses its ubiquitin ligase (E3) activity to suppress host immunity. Knocking down the expression of group III E2 genes in Nicotiana benthamiana diminished the AvrPtoB-promoted degradation of the Fen kinase and the AvrPtoB suppression of host immunity-associated programmed cell death. Importantly, silencing group III E2 genes also resulted in reduced pattern-triggered immunity (PTI). By contrast, programmed cell death induced by several effector-triggered immunity elicitors was not affected on group III-silenced plants. Functional characterization suggested redundancy among group III members for their role in the suppression of plant immunity by AvrPtoB and in PTI and identified UBIQUITIN-CONJUGATING11 (UBC11), UBC28, UBC29, UBC39, and UBC40 as playing a more significant role in PTI than other group III members. Our work builds a foundation for the further characterization of E2s in plant immunity and reveals that AvrPtoB has evolved a strategy for suppressing host immunity that is difficult for the plant to thwart.

We hypothesized that species of the Candida glabrata clade and species with phenotypic traits that overlap those of C. glabrata would produce white colonies on CHROMagar Candida medium. Of 154 isolates (seven species) tested, C. bracarensis, C. nivariensis, C. norvegensis, C. glabrata, and C. inconspicua produced white colonies; the Pichia fermentans group and C. krusei did not. Many of these species are difficult to identify phenotypically; white colonies may signal the need for the use of molecular approaches. PMID:18685009

On the vicissitudes of combining individual and group psychotherapy.

2009-01-01

Abstract Reviewing a series of articles in this special issue on combined treatment incorporating individual and group therapy, and in one instance couples therapy and a relationship group, the author provides a synoptic history of combined treatment, noting that the relational perspectives of psychoanalysis and systems theories of groups now provide conceptual frameworks for combined therapies. Taking up each article in turn, he considers that combined treatment poses particular problems while having certain advantages. He discusses the theoretical emphases and biases of each article, whether relational psychology, classical psychoanalysis, object relations theory, or self-psychology. He considers the roles of transference and countertransference, patient-therapist enactments, empathic attunement, "surrogate therapy" by the group members, and ethics in determining outcomes. In addition, the author notes how so-called difficult or regressed patients impact upon and are affected by the use of combined therapy modalities.

Mass care feeding for disaster evacuees is an important component of public health preparedness. If universities that offer a training course for registered dietitians could provide food assistance to the evacuated people in their campus, it could contribute to maintain their health. Many universities are expected to become a base of support activities for people affected by disaster. This study aimed to reveal disaster preparedness in a university that offers a training course for registered dietitians, from the aspect of provision of mass care feeding. As Japan has 124 universities that offer such training courses, this case study could serve as a useful reference for them and contribute to the improvement of health of the affected people. A group interview was conducted in University A in 2012. The participants included two faculty members in the course, a vice president, a staff member, and a faculty member in charge of disaster preparedness and response. Stockpiled foods were limited to dry bread and pre-processed rice. No alternative heat sources were stored. It was concluded that to provide nutrients other than carbohydrate, hot meals should be served for the evacuees. Additionally, it would be difficult to provide meal service when the essential utilities such as gas and electricity are disrupted. PMID:25114569

Closing the Generational Gap in Surgery: Why So Angry?

PubMed Central

2016-01-01

Summary: Significant and rapid changes in healthcare delivery are forcing surgeons into collaborative teams. Additionally, surgeons are faced with new bureaucratic requirements that do not directly impact patient care, but nevertheless require allocation of time and attention. Surgeons are required to communicate with an expanding group of individuals at various professional levels, adding further stress to daily tasks. Even the method of communication is undergoing rapid transformation. Some surgeons, especially those who are members of the Boomer or X Generation, find this revolution difficult to manage; whereas those who are members of the Y Generation may in fact be better equipped. Surgeons who either refuse to acknowledge these changes or simply lack emotional self-awareness run the risk of being labeled as disruptive. Behavioral techniques are explored which may help those surgeons who are having difficulty. PMID:27826481

Educating medical students to care for patients at the end-of-life is increasingly recognised as an essential component of training. Traditionally, medical student programmes are run by doctors, but patient care is delivered by an interprofessional team. Our programmes in the UK and USA independently developed a teaching experience led by an interprofessional team of palliative care health professionals. This study explores the palliative care health professionals' perceptions, regarding their unique role in medical student palliative care education. This is the first study to ascertain views of an interprofessional team delivering palliative care education to medical students. Focus groups enable interaction between members of the group as well as the generation of consensus of comments among group members. Two major themes were identified: perceived benefits and value of the experience, and the challenges and lessons learnt from the experiences. Despite different structures and settings, this experiential learning in palliative care provided a rewarding interprofessional experience that has historically been difficult to achieve. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Military families face many challenges due to deployment and parental separation, and this can be especially difficult for families with young children. The Strong Military Families (SMF) intervention is for military families with young children, and consists of two versions: the Multifamily Group, and a Home-based psychoeducational written materials program. The Multifamily Group was designed to enhance positive parenting through both educational components and in vivo feedback and support during separations and reunions between parents and children (n = 78 parents). In the present study, we examine parenting reflectivity and mental representations in mothers versus fathers in military families, service members versus civilian spouses/parenting partners, and before versus after participation in the SMF Multifamily Group and Home-based interventions. Parenting reflectivity and mental representations were coded from the Working Model of the Child Interview (WMCI; C.H. Zeanah & D. Benoit, 1995). Results suggest that neither parenting reflectivity nor WMCI typology differs between mothers and fathers in military families, or between service members and civilian parenting partners. Furthermore, there was substantial stability in parenting reflectivity and WMCI typology from baseline to posttest, but participation in the Multifamily Group, relative to Home-based, was associated with improvements in both parenting reflectivity and WMCI ratings from baseline to postintervention. © 2017 Michigan Association for Infant Mental Health.

Men with intellectual disability (ID) and sexually abusive behaviour are a disempowered and marginalised group. Nevertheless, as service users, they can be consulted and involved in a variety of different ways, including ascertaining their views of the services they receive. A group of 16 men with ID and sexually abusive behaviour were interviewed to ascertain their views approximately 2 months after completing a 1-year group cognitive behavioural treatment (CBT) for sexual offending. Two raters independently reviewed interview transcripts and participant responses were summarised. The most salient components of treatment recalled by participants were: sex education; legal and illegal behaviours and their consequences; and discussions about specific sexual assaults. Only 3 of the 16 participants stated that they had problems with sexual offending, and only 1 identified that he had learnt about victim empathy, although this is an important component of treatment. Having support, the knowledge that they had the same problems as other group members, and talking through problems, were appreciated as some of the "best things" about the group, while the "worst things" were generally person-specific. Participants had mixed views on talking about their own offences during group sessions and, overall, viewed the experience as difficult but helpful. Valuable insights into the aspects of treatment that group members found useful were explored. Such insights are often not captured by studies that assess the efficacy of treatment models using treatment-specific measures only, and these are important in defining the quality of services provided.

Acceptability of participatory social network analysis for problem-solving in Australian Aboriginal health service partnerships

PubMed Central

2012-01-01

Background While participatory social network analysis can help health service partnerships to solve problems, little is known about its acceptability in cross-cultural settings. We conducted two case studies of chronic illness service partnerships in 2007 and 2008 to determine whether participatory research incorporating social network analysis is acceptable for problem-solving in Australian Aboriginal health service delivery. Methods Local research groups comprising 13–19 partnership staff, policy officers and community members were established at each of two sites to guide the research and to reflect and act on the findings. Network and work practice surveys were conducted with 42 staff, and the results were fed back to the research groups. At the end of the project, 19 informants at the two sites were interviewed, and the researchers conducted critical reflection. The effectiveness and acceptability of the participatory social network method were determined quantitatively and qualitatively. Results Participants in both local research groups considered that the network survey had accurately described the links between workers related to the exchange of clinical and cultural information, team care relationships, involvement in service management and planning and involvement in policy development. This revealed the function of the teams and the roles of workers in each partnership. Aboriginal workers had a high number of direct links in the exchange of cultural information, illustrating their role as the cultural resource, whereas they had fewer direct links with other network members on clinical information exchange and team care. The problem of their current and future roles was discussed inside and outside the local research groups. According to the interview informants the participatory network analysis had opened the way for problem-solving by “putting issues on the table”. While there were confronting and ethically challenging aspects, these informants considered that with flexibility of data collection to account for the preferences of Aboriginal members, then the method was appropriate in cross-cultural contexts for the difficult discussions that are needed to improve partnerships. Conclusion Critical reflection showed that the preconditions for difficult discussions are, first, that partners have the capacity to engage in such discussions, second, that partners assess whether the effort required for these discussions is balanced by the benefits they gain from the partnership, and, third, that “boundary spanning” staff can facilitate commitment to partnership goals.

How Older Adults and Their Families Perceive Family Talk about Aging-Related EOL Issues: A Dialectical Analysis.

2017-04-17

For older adults, approaching end-of-life (EOL) brings unique transitions related to family relationships. Unfortunately, most families greatly underestimate the need to discuss these difficult issues. For example, parents approaching EOL issues often struggle with receiving assistance from others, avoiding family conflict, and maintaining their sense of personhood. In addition, discussions of EOL issues force family members to face their parents' mortality, which can be particularly difficult for adult children to process emotionally. This study explored aging issues identified by aging parents and their families as they traverse these impending EOL changes. Ten focus groups of seniors ( n = 65) were conducted. Focus groups were organized according to race (African-American/European-American), gender, and whether the older adult was living independently or in an assisted care facility. When asked open-ended questions about discussing aging and EOL issues with family members, participants revealed tensions that led us to consider Relational Dialectics Theory as a framework for analysis. The predominant tension highlighted in this report was certainty versus uncertainty, with the two sub-themes of sustained life versus sustained personhood and confronting versus avoiding EOL issues. For these data, there were more similarities than differences as a result of gender, race, or living situation than one might expect, although culture and financial status were found to be influential in the avoidance of EOL discussions. The results of this study help to provide additional insight into relational dialectics related to aging, EOL, and the importance of communication in facilitating family coping.

The aim was to describe the strengths and weaknesses, from team member perspectives, of working with the Global Trigger Tool (GTT) method of retrospective record review to identify adverse events causing patient harm. A qualitative, descriptive approach with focus group interviews using content analysis. 5 Swedish hospitals in 2011. 5 GTT teams, with 5 physicians and 11 registered nurses. 5 focus group interviews were carried out with the five teams. Interviews were taped and transcribed verbatim. 8 categories emerged relating to the strengths and weaknesses of the GTT method. The categories found were: Usefulness of the GTT, Application of the GTT, Triggers, Preventability of harm, Team composition, Team tasks, Team members' knowledge development and Documentation. Gradually, changes in the methodology were made by the teams, for example, the teams reported how the registered nurses divided up the charts into two sets, each being read respectively. The teams described the method as important and well functioning. Not only the most important, but also the most difficult, was the task of bringing the results back to the clinic. The teams found it easier to discuss findings at their own clinics. The GTT method functions well for identifying adverse events and is strengthened by its adaptability to different specialties. However, small, gradual methodological changes together with continuingly developed expertise and adaption to looking at harm from a patient's perspective may contribute to large differences in assessment over time.

"Is all the stuff about neurons necessary?" The development of lay summaries to disseminate findings from the Newcastle Cognitive Function after Stroke (COGFAST) study.

Why did we do this study? It can be difficult for scientists to communicate their research findings to the public. This is partly due to the complexity of translating scientific language into words that the public understand. Further, it may be hard for the public to find out about and locate information about research studies. We aimed to adapt some scientific articles about the links between dementia and stroke into lay summaries to be displayed online for the general public. How did we do it? We collaborated with five people from a volunteer organisation, VOICENorth. They took part in two group discussions about studies reporting on the link between dementia and stroke, and selected four studies to translate into lay summaries and display on a website. We discussed the layout and language of the summaries and made adaptations to make them more understandable to the general public. What did we find? We were able to work with members of the public to translate research findings into lay summaries suitable for a general audience. We made changes to language and layout including the use of 'question and answer' style layouts, the addition of a reference list of scientific terms, and removing certain words. What does this mean? Working with members of the public is a realistic way to create resources that improve the accessibility of research findings to the wider public. Background Scientific research is often poorly understood by the general public and difficult for them to access. This presents a major barrier to disseminating and translating research findings. Stroke and dementia are both major public health issues, and research has shown lifestyle measures help to prevent them. This project aimed to select a series of studies from the Newcastle Cognitive Function after Stroke cohort (COGFAST) and create lay summaries comprehensible and accessible to the public. Methods We used a focus group format to collaborate with five members of the public to review COGFAST studies, prioritise those of most interest to the wider public, and modify the language and layout of the selected lay summaries. Focus groups were audio-taped and the team used the data to make iterative amendments, as suggested by members of the public, to the summaries and to a research website. We calculated the Flesch reading ease and Flesch-Kincaid grade level for each summary before and after the changes were made. Results In total, we worked with five members of the public in two focus groups to examine draft lay summaries, created by researchers, relating to eight COGFAST studies. Members of the public prioritised four COGFAST lay summaries according to the importance of the topic to the general public. We made a series of revisions to the summaries including the use of 'question and answer' style layouts, the addition of a glossary, and the exclusion of scientific jargon. Group discussion highlighted that lay summaries should be engaging, concise and comprehensible. We incorporated suggestions from members of the public into the design of a study website to display the summaries. The application of existing quantitative tools to estimate readability resulted in an apparently paradoxical increase in complexity of the lay summaries following the changes made. Conclusion This study supports previous literature demonstrating challenges in creating generic guidelines for researchers to create lay summaries. Existing quantitative metrics to assess readability may be inappropriate for assessing scientific lay summaries. We have shown it is feasible and successful to involve members of the public to create lay summaries to communicate the findings of complex scientific research. Trial registration Not applicable to the lay summary project.

Relational factors in psychopathological responses to childbirth.

Childbirth can represent for women the time of greatest vulnerability experience, often associated with being out of control, loneliness or sadness. One hundred and sixty women who had 'normal' births were assessed within 48 hours on potential predictive measures and at 3-6 months post-partum for PTSD. Symptoms of depression, anxiety, perceived and desired support by family members, friends, medical personnel were also assessed. t-Test and chi-square were used to analyze, differences between 'risk group' and 'non-risk group'. Few women (1.25%) showed questionnaire responses suggesting clinically significant levels on PTSD; other women (28.75%) reported clinically significant symptoms for at least one subscale. Being at the first delivery experience, together with perceptions of low levels of support from family members and medical personnel, were found to be related to experience of post-traumatic stress symptoms. Anxiety for the child and previous depression are also related to such symptoms. Moreover, anxiety and depression are related to a difficult recognition of the support received, as well as to the desire for more support, in the care of the newborn, from medical professionals.

Women and Couples in Isolated Extreme Environments: Applications for Long-Duration Missions

NASA Astrophysics Data System (ADS)

Leon, G. R.; Sandal, G. M.

Analysis of the functioning of different types of expedition teams provides a range of analogs from which to make judgments about human limitations during long-duration space exploration, and possible countermeasures for dealing with these problems. Some of the limitations identified are the tendency for participants in all-male groups to be higWy competitive and unlikely to share personal concerns with each other. Women in mixed-gender groups often experience interpersonal stress because male team members confide concerns to them, although not necessarily encouraging reciprocal sharing. Women have also been found to take the role of "peacemakers", reducing competition and tension among male participants. Three multinational polar expedition groups were studied that varied in crew composition and nature of the environmental and work conditions. Group 1 consisted of two women who skied the length of the Antarctic continent on a 97 day traverse, hauling sleds weighing up to 114 kg. The participants were highly compatible in interests and prior expedition experience, and in appreciation of the knowledge and judgment of their partner. Assessment measures were as follows: Multidimensional Personality Inventory (MPQ), Personality Characteristics Inventory (PCI), and Utrecht Coping List (UCL) completed prior to the expedition; Weekly Rating Form (WRF) examining intra/interpersonal variables, work performance, and environmental factors during the trek; semi-structured interview conducted at the end of the expedition. Roth team members scored relatively high on the MPQ personality trait of Absorption; they also were classified as "the right stuff' based on PCI findings. Bach provided emotional support to her teammate during difficult times, yet respected the others' autonomy and self -esteem. A dyadic process of shared cognition was evident in the substantial similarities in approach to solving problems, and the cooperative nature of decision making. Group 2 was composed of four women from Greenland, Denmark, UK and Russia who traversed the Greenland ice by ski. The participants did not know each other prior to the expedition. Three were classified as "the right stuff' based on PCI findings. Diary and post-expedition reports indicated that incidents of interpersonal tension were often related to fatigue, homesickness, pain or cold. The participants also indicated that respect and tolerance for differences between them, as weIl as mutual emotional support were crucial factors for the successful completion of the expedition. Group 3 consisted of 3 married couples and the 2 1/2 year old child of the leader and his wife. Five of the crew sailed a small boat from Norway to the Canadian High Arctic; the leader's wife and child joined the team in Greenland. Over a 9 month period, the icelocked boat was ilie center of habitation, scientific, and other activities. Three of the group carried out a 6 week exploratory trek at the end of the winter-over. Participants completed the MPQ prior to the expedition, a WRF over the entire Arctic period, and a semi-structured personality interview at the close of the interval during which the entire group was together. AlI participants scored relatively highest on the Absorption scale, manifested in the salutory experience of enjoying and becoming engrossed in the beauty of the environment. WRF and interview findings indicated that team members consistently reported that the emotional support of and ability to confide in their partner were extremely important in alleviating interpersonal tensions with other team members, and contributed to the overall effective functioning of the group. Reported level of emotional response to stress and coping patterns used while in the stationary habitat were consistent with WRF responses during the later exploratory trek. The woman team member on the trek reported more discomfort regarding personal hygiene issues and fear of injury .In alI groups, the salience of the overriding goal of the expedition was a highly important factor in coping and striving for optimal work performance. Maintainil}g the self-esteem of each group member at difficult times such as injury or psychological stress is also very important for optimal work performance and mission success. Women appear to add an element of emotional support and help to other team members that is not as evident in all-male groups. However, the need for women in these groups to also have a confidant with whom to share concerns may increase the overall efficiency of isolated groups. The effectiveness of the decision-making processes by co-equal partners suggests a viable alternative for planetary exploration than the usual military command structure. Moreover, a group composed of couples with strong bonds with their partner is another paradigm to consider for crew selection for long-duration missions.

Professional society membership enhances career development and productivity by offering opportunities for networking and learning about recent advances in the field. The quality and contribution of such societies can be measured in part through the academic productivity, career status, and funding success rates of their members. Here, using Scopus, NIH RePORTER, and departmental websites, we compare characteristics of the Shock Society membership to those of the top 55 NIH-funded American university and hospital-based departments of surgery. Shock Society members' mean number of publications, citations and H-indices were all significantly higher than those of non-members in surgery departments (P < 0.001). A higher percentage of members also have received funding from the NIH (42.5% vs. 18.5%, P < 0.001). Regression analysis indicated that members were more likely to have NIH funding compared with non-members (OR 1.46, 95% CI 1.12-1.916). Trauma surgeons belonging to the Shock Society had a higher number of publications and greater NIH funding than those who did not (130.4 vs. 42.7, P < 0.001; 40.4% vs. 8.5%, P < 0.001). Aggregate academic metrics from the Shock Society were superior to those of the Association for Academic Surgery and generally for the Society of University Surgeons as well. These data indicate that the Shock Society represents a highly academic and productive group of investigators. For surgery faculty, membership is associated with greater academic productivity and career advancement. While it is difficult to ascribe causation, certainly the Shock Society might positively influence careers for its members.

Compelling Evidence that Exposure Therapy for PTSD Normalizes Brain Function.

Roy, Michael J; Costanzo, Michelle E; Blair, James R; Rizzo, Albert A

2014-01-01

Functional magnetic resonance imaging (fMRI) is helping us better understand the neurologic pathways involved in posttraumatic stress disorder (PTSD). We previously reported that military service members with PTSD after deployment to Iraq or Afghanistan demonstrated significant improvement, or normalization, in the fMRI-measured activation of the amygdala, prefrontal cortex and anterior cingulate gyrus following exposure therapy for PTSD. However, our original study design did not include repeat scans of control participants, rendering it difficult to discern how much of the observed normalization in brain activity is attributable to treatment, rather than merely a practice effect. Using the same Affective Stroop task paradigm, we now report on a larger sample of PTSD-positive combat veterans that we treated with exposure therapy, as well as a combat-exposed control group of service members who completed repeat scans at 3-4 month intervals. Findings from the treatment group are similar to our prior report. Combat controls showed no significant change on repeat scanning, indicating that the observed differences in the intervention group were in fact due to treatment. We continue to scan additional study participants, in order to determine whether virtual reality exposure therapy has a different impact on regional brain activation than other therapies for PTSD.

The role of national ethics commissions in Finland.

PubMed

Halila, Ritva

2003-08-01

There are six national ethics commissions in Finland. The National Advisory Board on Research Ethics was first established in 1991, followed by the National Advisory Board on Biotechnology and the Board on Gene Technology in 1995. The National Advisory Board on Health Care Ethics was established in 1998, followed by its Sub-Committee on Medical Research Ethics in 1999. The Co-operation Group for Laboratory Animal Sciences was established in 2001. Only the Board on Gene Technology works as a national authority and gives binding opinions and recommendations about the use of genetically modified organisms. The Sub-Committee on Medical Research Ethics acts a national research ethics committee and gives opinions about research projects. Other advisory boards do not make legally binding decisions, but their expertise gives a lot of power to their opinions and statements. The commissions work in close collaboration with each other, having regular meetings. They arrange seminars and conferences, and share information with each other. The commissions also share duties and information in international collaboration. How the voice and opinions of these commissions is heard in society lies in the wide, multi-professional expertise of their members. Large commissions and wide expertise may make it difficult to find consensus in their opinions and statements, although wide expertise may, more than discussion in a small expert group, help to further process difficult ethical issues. Collaboration between different bodies is important in order to share duties, and also to add more emphasis to the statements and opinions where different bodies share interests. In our country, the interest that national commissions share is research ethics, where the advisory boards and their members have discharged collaborative activities for years.

Is mental heal care in women's prisons adequate?

PubMed

Sims, Joyce

Some individuals and groups, find it difficult to seek healthcare, including prisoners. This group is recognised as needing input but are often difficult to engage, yet failure to meet their needs can be devastating for the health of individuals and have wider implications on society. This qualitative study explored the perceptions of female prisoners who had not yet consulted the mental health team. I aimed to find out what support these women seek out while in prison, what difficulties they encountered in getting psychological help and whether they avoided statutory mental health services. Participants revealed during semistructured interviews that continuing to have a caring role for their families encouraged them to feel more positive and supported. Support from family members, specialist prison officers and the multi-faith centre staff team was also highly regarded. Some of the participants reported experiencing problems self-referring to prison mental health services, for example when transferred to a new prison. They identified the prison application system and inreach administrative failings as weaknesses, alongside other variables. I found that prisoners did not avoid mental health services and often once settled in the prison, they reconsidered their need for statutory support.

Psychiatric nursing staff members' reflections on participating in group-based clinical supervision: a semistructured interview study.

This paper is a report of an interview study exploring psychiatric hospital nursing staff members' reflections on participating in supervision. Clinical supervision is a pedagogical process designed to direct, develop, and support clinical nurses. Participation rates in clinical supervision in psychiatric settings have been reported to be relatively low. Qualitative research indicates that staff members appreciate clinical supervision, but paradoxically, do not prioritize participation and find participation emotionally challenging. Little is known about these contradictory experiences and how they influence participation rates. Twenty-two psychiatric hospital nursing staff members were interviewed with a semistructured interview guide. Interview transcripts were interpreted by means of Ricoeur's hermeneutic method. The respondents understood clinical supervision to be beneficial, but with very limited impact on their clinical practice. Neither management nor the staff effectively prioritized clinical supervision, which added to a downward spiral where low levels of participation undermined the potential benefits of clinical supervision. The respondents embraced and used alternative forums for getting emotional support among peers, but maintained that formalized supervision was the only forum for reflection that could solve the most difficult situations. © 2011 The Authors.

BARTER: Behavior Profile Exchange for Behavior-Based Admission and Access Control in MANETs

NASA Astrophysics Data System (ADS)

Frias-Martinez, Vanessa; Stolfo, Salvatore J.; Keromytis, Angelos D.

Mobile Ad-hoc Networks (MANETs) are very dynamic networks with devices continuously entering and leaving the group. The highly dynamic nature of MANETs renders the manual creation and update of policies associated with the initial incorporation of devices to the MANET (admission control) as well as with anomaly detection during communications among members (access control) a very difficult task. In this paper, we present BARTER, a mechanism that automatically creates and updates admission and access control policies for MANETs based on behavior profiles. BARTER is an adaptation for fully distributed environments of our previously introduced BB-NAC mechanism for NAC technologies. Rather than relying on a centralized NAC enforcer, MANET members initially exchange their behavior profiles and compute individual local definitions of normal network behavior. During admission or access control, each member issues an individual decision based on its definition of normalcy. Individual decisions are then aggregated via a threshold cryptographic infrastructure that requires an agreement among a fixed amount of MANET members to change the status of the network. We present experimental results using content and volumetric behavior profiles computed from the ENRON dataset. In particular, we show that the mechanism achieves true rejection rates of 95% with false rejection rates of 9%.

Gossip and ostracism promote cooperation in groups.

PubMed

Feinberg, Matthew; Willer, Robb; Schultz, Michael

2014-03-01

The widespread existence of cooperation is difficult to explain because individuals face strong incentives to exploit the cooperative tendencies of others. In the research reported here, we examined how the spread of reputational information through gossip promotes cooperation in mixed-motive settings. Results showed that individuals readily communicated reputational information about others, and recipients used this information to selectively interact with cooperative individuals and ostracize those who had behaved selfishly, which enabled group members to contribute to the public good with reduced threat of exploitation. Additionally, ostracized individuals responded to exclusion by subsequently cooperating at levels comparable to those who were not ostracized. These results suggest that the spread of reputational information through gossip can mitigate egoistic behavior by facilitating partner selection, thereby helping to solve the problem of cooperation even in noniterated interactions.

Reducing vertices in property graphs

Graph databases are constantly growing, and, at the same time, some of their data is the same or similar. Our experience with the management of the existing databases, especially the bigger ones, shows that certain vertices are particularly replicated there numerous times. Eliminating repetitive or even very similar data speeds up the access to database resources. We present a modification of this approach, where similarly we group together vertices of identical properties, but then additionally we join together groups of data that are located in distant parts of a graph. The second part of our approach is non-trivial. We show that the search for a partition of a given graph where each member of the partition has only pairwise distant vertices is NP-hard. We indicate a group of heuristics that try to solve our difficult computational problems and then we apply them to check the the effectiveness of our approach. PMID:29444127

Tamper-indicating device having a glass body

Johnston, Roger G.; Garcia, Anthony R. E.

2003-04-29

A tamper-indicating device is described. The device has a first glass body member and a second glass body member that are attached to each other through a hasp. The glass body members of the device can be tempered. The body members can be configured with hollow volumes into which powders, microparticles, liquids, gels, or combinations thereof are sealed. The choice, the amount, and the location of these materials can produce a visible, band pattern to provide each body member with a unique fingerprint identifier, which makes it extremely difficult to repair or replace once it is damaged in order to avoid tamper detection.

Legal aspects of clinical ethics committees.

PubMed

Hendrick, J

2001-04-01

In an increasingly litigious society where ritual demands for accountability and "taking responsibility" are now commonplace, it is not surprising that members of clinical ethics committees (CECs) are becoming more aware of their potential legal liability. Yet the vulnerability of committee members to legal action is difficult to assess with any certainty. This is because the CECs which have been set up in the UK are--if the American experience is followed--likely to vary significantly in terms of their functions, procedures, composition, structures and authority. As a consequence it is difficult to generalize about the legal implications. Nevertheless, despite these difficulties this article will outline the broad legal principles governing the potential liability of committee members. It will also consider the relationship between CECs and the courts. It begins, however, with a brief analysis of the relationship between ethics and law in committee deliberations, and in particular of the role of law and legal expertise on CECs.

To study an asteroid family it is crucial to determine reliably the list of its members, i.e. to reduce the number of interlopers as much as possible. However, as the number of known asteroids increases fast it becomes more and more difficult to obtain robust list of members of an asteroid family. To cope with these challenges we are proposing a new approach that may help to significantly reduce presence of interlopers among the family members.

Managing a customer portfolio at the individual level is the most difficult and most promising endeavor. An individual level consumer portfolio does not mean creating marketing materials and advertising campaigns customized for every member of your health plan. What it does mean is developing segmentation models based on consumer preferences extracted directly from your members, not socioeconomic or other demographic models. The most important information to extract is perceptions on how much and what kind of value members want from the organization.

Deviance as adherence to injunctive group norms: the overlooked role of social identification in deviance.

PubMed

Crane, Monique F; Platow, Michael J

2010-12-01

We currently report three studies investigating group members' expressions of dissatisfaction and discontent with the behaviour and attitudes of their in-group members. Our analysis examines the context in which group members will deviate from actual group member behaviour. We argue that highly identifying group members will challenge fellow group member behaviour when that group member behaviour is perceived to violate injunctive group norms. Further, we predicted that high identifiers would still challenge such group member behaviour even if that behaviour were conducted by a majority of group members. Thus, high identifiers were predicted to express descriptively deviant opinions when the behaviour of other members contravenes injunctive group norms. In Studies 1 and 2, group-level self-definition served as a moderator in the relationship between the expression of discontent and perceived injunctive norm violation; in Study 3, group-level self-investment served as this moderator. The findings supported our predictions. This support was particularly strong when a majority of group members violated group norms. Implications for the analysis of the relationship between social identification and deviance are discussed.

Emotional resistance building: how family members of loved ones undergoing chemotherapy treatment process their fear of emotional collapse.

2015-04-01

To explore family members' experiences when their loved one is undergoing chemotherapy treatment as an outpatient for newly diagnosed colorectal cancer and to develop an explanatory theory of how they process their main concern. Most individuals with cancer are now treated as outpatients and cared for by family members. International research highlights the many side effects of chemotherapy, which in the absence of specific information and/or experience can be difficult for family members to deal with. Unmet needs can have an impact on the health of both patients and family members. Classic grounded theory methodology was used for this study. Using classic grounded theory methodology, family members (n = 35) of patients undergoing chemotherapy treatment for cancer were interviewed (June 2010-July 2011). Data were analysed using the concurrent processes of constant comparative analysis, data collection, theoretical sampling and memo writing. The main concern that emerged for participants was fear of emotional collapse. This fear was dealt with through a process conceptualized as 'Emotional Resistance Building'. This is a basic social process with three phases: 'Figuring out', 'Getting on with it' and 'Uncertainty adjustment'. The phases are not linear, but interrelated as participants can be in any one or more of the phases at any one time. This theory has the potential to be used by healthcare professionals working in oncology to support family members of patients undergoing chemotherapy. New ways of supporting family members through this most difficult and challenging period are articulated within this theory. © 2014 John Wiley & Sons Ltd.

2009-01-01

Selection and socialization have been implicated in friendship homophily, but the relative contributions of each are difficult to measure simultaneously because of the nonindependent nature of the data. To address this problem, the authors applied a multiple-groups longitudinal actor–partner interdependence model (D. A. Kashy & D. A. Kenny, 2000) for distinguishable dyads to 3 consecutive years of intoxication frequency data from a large community-based sample of Swedish youth. Participants, ranging from 12 to 18 years old (M = 14.35, SD = 1.56) at the start of the study, included 902 adolescents (426 girls and 476 boys) with at least one reciprocated friend during at least one time point and 212 adolescents (84 girls and 128 boys) without reciprocated friends at any time. Similarity estimates indicated strong effects for selection and socialization in friends’ intoxication frequency. Over time, younger members of these dyads had less stable patterns of intoxication than older members, largely because younger partners changed their drinking behavior to resemble that of older partners.

Hospitalized palliative patients need to keep in touch with their loved ones. Regular social contact may be especially difficult for individuals on palliative care in-patient units due to the isolating nature of hospital settings. Technology can help mitigate isolation by facilitating social connection. This study aimed to explore the acceptability of introducing internet-based communication and information technologies for patients on a palliative care in-patient unit. In the first phase of the Keep in Touch (KIT) project, a diverse group of key informants were consulted regarding their perspectives on web-based communication on in-patient palliative care units. Participants included palliative patients, family members, direct care providers, communication and information technology experts, and institutional administrators. Data was collected through focus groups, interviews and drop-in consultations, and was analyzed for themes, consensus, and major differences across participant groups. Hospitalized palliative patients and their family members described the challenges of keeping in touch with family and friends. Participants identified numerous examples of ways that communication and information technologies could benefit patients' quality of life and care. Patients and family members saw few drawbacks associated with the use of such technology. While generally supportive, direct care providers were concerned that patient requests for assistance in using the technology would place increased demands on their time. Administrators and IT experts recognized issues such as privacy and costs related to offering these technologies throughout an organization and in the larger health care system. This study affirmed the acceptability of offering internet-based communication and information technologies on palliative care in-patient units. It provides the foundation for trialing these technologies on a palliative in-patient unit. Further study is needed to confirm the feasibility of offering these technologies at the bedside.

VMCast: A VM-Assisted Stability Enhancing Solution for Tree-Based Overlay Multicast

PubMed Central

Gu, Weidong; Zhang, Xinchang; Gong, Bin; Zhang, Wei; Wang, Lu

2015-01-01

Tree-based overlay multicast is an effective group communication method for media streaming applications. However, a group member’s departure causes all of its descendants to be disconnected from the multicast tree for some time, which results in poor performance. The above problem is difficult to be addressed because overlay multicast tree is intrinsically instable. In this paper, we proposed a novel stability enhancing solution, VMCast, for tree-based overlay multicast. This solution uses two types of on-demand cloud virtual machines (VMs), i.e., multicast VMs (MVMs) and compensation VMs (CVMs). MVMs are used to disseminate the multicast data, whereas CVMs are used to offer streaming compensation. The used VMs in the same cloud datacenter constitute a VM cluster. Each VM cluster is responsible for a service domain (VMSD), and each group member belongs to a specific VMSD. The data source delivers the multicast data to MVMs through a reliable path, and MVMs further disseminate the data to group members along domain overlay multicast trees. The above approach structurally improves the stability of the overlay multicast tree. We further utilized CVM-based streaming compensation to enhance the stability of the data distribution in the VMSDs. VMCast can be used as an extension to existing tree-based overlay multicast solutions, to provide better services for media streaming applications. We applied VMCast to two application instances (i.e., HMTP and HCcast). The results show that it can obviously enhance the stability of the data distribution. PMID:26562152

Social Groups Prioritize Selective Attention to Faces: How Social Identity Shapes Distractor Interference

PubMed Central

Hill, LaBarron K.; Williams, DeWayne P.; Thayer, Julian F.

2016-01-01

Human faces automatically attract visual attention and this process appears to be guided by social group memberships. In two experiments, we examined how social groups guide selective attention toward in-group and out-group faces. Black and White participants detected a target letter among letter strings superimposed on faces (Experiment 1). White participants were less accurate on trials with racial out-group (Black) compared to in-group (White) distractor faces. Likewise, Black participants were less accurate on trials with racial out-group (White) compared to in-group (Black) distractor faces. However, this pattern of out-group bias was only evident under high perceptual load—when the task was visually difficult. To examine the malleability of this pattern of racial bias, a separate sample of participants were assigned to mixed-race minimal groups (Experiment 2). Participants assigned to groups were less accurate on trials with their minimal in-group members compared to minimal out-group distractor faces, regardless of race. Again, this pattern of out-group bias was only evident under high perceptual load. Taken together, these results suggest that social identity guides selective attention toward motivationally relevant social groups—shifting from out-group bias in the domain of race to in-group bias in the domain of minimal groups—when perceptual resources are scarce.

Chaitin, Julia

2003-10-01

Undertaking research on individuals who have experienced social traumas, such as being a victim or perpetrator of genocides and wars, presents difficult decisions for qualitative researchers. Deciding how to deal with these issues becomes more problematic when the researcher is a member of the society in conflict. To do this work, and to work collaboratively with researchers from the other side, sensitive ways to collect data have to be chosen. Interpretations of the materials can be no less difficult: Analyses often lead to information and understandings that may be difficult for the researcher to deal with from ethical, moral, and personal standpoints, especially when he or she is a member of the society and culture under study. In this keynote address, the author explores methodological and ethical issues connected to these topics. She brings examples from her work on the Palestinian-Israeli conflict and focuses on use of the life story methodology.

Introduction Preclinical dental education promotes development of competency and expertise before students work on patients, but this phase is devoid of exposure to real patients leading to challenges in teaching-learning. Aim The aim of this study was to explore the challenges faced by students during the process of learning preclinical prosthodontics. Materials and Methods Two Focus Group Discussions (FGDs) were conducted with two different groups of students and one FGD was held with prosthodontics faculty. The FGDs explored the student’s and faculty perceptions on the topics which were difficult for the students to understand and their suggestions on how these topics can be made easier to understand. The discussions were audio taped with prior consent and transcribed. Results The students and the faculty felt that the subject of prosthodontics is vast, difficult to visualize and also difficult to correlate theory with practical aspects. Lack of clinical exposure coupled with use of conventional methods of teaching were identified as reasons for difficulty in understanding the subject. Both students and faculty members suggested that use of simulation, demonstrations, and videos could augment the learning process for the students. Early clinical exposure will help solve many problems encountered during learning and contribute to a better understanding. Conclusion The students and faculty expressed a “need” for early clinical exposure to enhance the learner’s understanding of the preclinical aspects of the subject. The present study highlights the need for change in instruction methods to enhance the learning experiences in preclinical prosthodontics of dental undergraduate students in India. PMID:28969263

Infection control education: how to make an impact--tools for the job.

PubMed

Farrington, Mark

2007-06-01

Infection control education is difficult and time consuming, but there is persuasive evidence to demonstrate its effectiveness. When Infection Control practitioners are educating and influencing healthcare workers, compliance with the well-established guidance on implementation of health service research is advisable, and thus educative efforts must be repeated and administered as part of a concerted and multifaceted approach. Infection Control education must be specifically designed for and targeted at the groups of staff concerned, and medical staff pose especial problems. Recruitment of clinical champions from peer groups, and direct approaches from medical members of the Infection Control team are usually needed. Familiarity with only a limited range of published evidence is needed to answer the majority of clinicians who challenge Infection Control practices, and referral to higher medical and managerial authority is required very infrequently and as a last resort. Some recent initiatives in the NHS in England may make Infection Control education more difficult, and these are reviewed. New sanctions have been made available to hospitals and Infection control teams in the UK with the passing of the Health Act in 2006, and the effects of these allied to educative interventions on benchmarks such as hospitals' MRSA bacteraemia rates will be observed with interest.

Certain member states of the European Union (EU) have already achieved successes in improving indoor environmental quality, such as controlling certain contaminants (e.g., environmental tobacco smoke) or developing nationwide policies that address indoor air generally. However, a common European approach to achieving healthy indoor environments is desirable for several reasons including providing a broader recognition of the problem of unhealthy indoor air, setting a policy example for all 27 EU member states, and achieving greater public health equity across the different European nations. In this article we address the question "Why is it so difficult in the EU to develop a coherent approach on indoor environment?" We identify and describe four main barriers: a) the subsidiarity principle in EU policymaking, introducing decentralization of decision making to the member states; b) fragmentation of the topic of the indoor environment; c) the differences in climate and governance among different member states that make a common policy difficult; and d) economic issues. We discuss potential lessons and recommendations from EU and U.S. successes in achieving healthier indoor environments through various policy mechanisms.

The epidemiology of chronic viral infections, such as those caused by Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV), is affected by the risk group structure of the infected population. Risk groups are defined by each of their members having acquired infection through a specific behavior. However, risk group definitions say little about the transmission potential of each infected individual. Variation in the number of secondary infections is extremely difficult to estimate for HCV and HIV but crucial in the design of efficient control interventions. Here we describe a novel method that combines epidemiological and population genetic approaches to estimate the variation in transmissibility of rapidly-evolving viral epidemics. We evaluate this method using a nationwide HCV epidemic and for the first time co-estimate viral generation times and superspreading events from a combination of molecular and epidemiological data. We anticipate that this integrated approach will form the basis of powerful tools for describing the transmission dynamics of chronic viral diseases, and for evaluating control strategies directed against them.

Multi-Vehicle Function Tracking by Moment Matching

NASA Astrophysics Data System (ADS)

Avant, Trevor

The evolution of many natural and man-made environmental events can be represented as scalar functions of time and space. Examples include the boundary and intensity of wildfires, of waste spills in bodies of water, and of natural emissions of methane from the earth. The difficult task of understanding and monitoring these processes can be accomplished through the use of coordinated groups of vehicles. This thesis devises a method to determine positions of the members of a group of vehicles in the domain of a scalar function which lead to effective sensing of the function. This method involves equating the moments of a scalar function to the moments of a group of positions, which results in a system of polynomial equations to be solved. This methodology also allows for other explicit geometric constraints, in the form of polynomial equations, to be imposed on the vehicles. Several example simulations are shown to demonstrate the advantages and challenges associated with the moment matching technique.

While donation after circulatory death (DCD) has expanded options for organ donation, many who wish to donate are still unable to do so. We conducted face-to-face interviews with family members (N = 15) who had direct experience with unsuccessful DCD and 5 focus groups with professionals involved in the donation process. We used qualitative content analysis to characterize the harms of nondonation as perceived by participants. Participants reported a broad spectrum of harms affecting organ recipients, donors, and donor families. Harms included waste of precious life-giving organs and hospital resources, inability to honor the donor's memory and character, and impaired ability for families to make sense of tragedy and cope with loss. Donor families empathized with the initial hope and ultimate despair of potential recipients who must continue their wait on the transplant list. Focus group members reinforced these findings and highlighted the struggle of families to navigate the uncertainty regarding the timing of death during the donation process. While families reported significant harm, many appreciated the donation attempt. These findings highlight the importance of organ donation to donor families and the difficult experiences associated with current processes that could inform development of alternative donation strategies. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

When is deliberate killing of young children justified? Indigenous interpretations of infanticide in Bolivia.

In the Andes, as elsewhere, infanticide is a difficult challenge that remains largely undocumented and misunderstood. From January to March 2004 we used community-based vital event surveillance systems, discussions with health staff, ethnographic interviews, and focus group discussions among Aymara men and women from two geographically distinct sites in the Andes of Bolivia to provide insights into the practice of infanticide. We noted elevated mortality at both sites. In one location, suspected causes of infanticide were especially high for girls. We also observed that community members maintain beliefs that justify infanticide under certain circumstances. Among the Aymara, justification for infanticide was both biological (deformities and twinship) and social (illegitimate birth, family size and poverty). Communities generally did not condemn killing when reasons for doing so were biological, but the taking of life for social reasons was rarely justified. In this cultural context, strategies to address the challenge of infanticide should include education of community members about alternatives to infanticide. At a program level, planners and implementers should target ethnic groups with high levels of infanticide and train health care workers to detect and address multiple warning signs for infanticide (for example, domestic violence and child maltreatment) as well as proxies for infant neglect and abuse such as mother/infant separation and bottle use.

Objectives To explore the 'added value' that general practitioners (GPs) bring to commissioning in the English NHS. We describe the experience of Clinical Commissioning Groups (CCGs) in the context of previous clinically led commissioning policy initiatives. Methods Realist evaluation. We identified the programme theories underlying the claims made about GP 'added value' in commissioning from interviews with key informants. We tested these theories against observational data from four case study sites to explore whether and how these claims were borne out in practice. Results The complexity of CCG structures means CCGs are quite different from one another with different distributions of responsibilities between the various committees. This makes it difficult to compare CCGs with one another. Greater GP involvement was important but it was not clear where and how GPs could add most value. We identified some of the mechanisms and conditions which enable CCGs to maximize the 'added value' that GPs bring to commissioning. Conclusion To maximize the value of clinical input, CCGs need to invest time and effort in preparing those involved, ensuring that they systematically gather evidence about service gaps and problems from their members, and engaging members in debate about the future shape of services.

The assessment and ongoing management of dementia falls largely on family physicians. This pilot study explored perceived roles and attitudes towards the provision of dementia care from the perspectives of family physicians and specialists. Semi-structured, one-to-one interviews were conducted with six family physicians and six specialists (three geriatric psychiatrists, two geriatricians, and one neurologist) from University of Toronto-affiliated hospitals. Transcripts were subjected to thematic content analysis. Physicians' clinical experience averaged 16 years. Both physician groups acknowledged that family physicians are more confident in diagnosing/treating uncomplicated dementia than a decade ago. They agreed on care management issues that warranted specialist involvement. Driving competency was contentious, and specialists willingly played the "bad cop" to resolve disputes and preserve long-standing therapeutic relationships. While patient/caregiver education and support were deemed essential, most physicians commented that community resources were fragmented and difficult to access. Improving collaboration and communication between physician groups, and clarifying the roles of other multi-disciplinary team members in dementia care were also discussed. Future research could further explore physicians' and other multi-disciplinary members' perceived roles and responsibilities in dementia care, given that different health-care system-wide dementia care strategies and initiatives are being developed and implemented across Ontario.

Similarity-Dissimilarity Competition in Disjunctive Classification Tasks

2013-01-01

Typical disjunctive artificial classification tasks require participants to sort stimuli according to rules such as “x likes cars only when black and coupe OR white and SUV.” For categories like this, increasing the salience of the diagnostic dimensions has two simultaneous effects: increasing the distance between members of the same category and increasing the distance between members of opposite categories. Potentially, these two effects respectively hinder and facilitate classification learning, leading to competing predictions for learning. Increasing saliency may lead to members of the same category to be considered less similar, while the members of separate categories might be considered more dissimilar. This implies a similarity-dissimilarity competition between two basic classification processes. When focusing on sub-category similarity, one would expect more difficult classification when members of the same category become less similar (disregarding the increase of between-category dissimilarity); however, the between-category dissimilarity increase predicts a less difficult classification. Our categorization study suggests that participants rely more on using dissimilarities between opposite categories than finding similarities between sub-categories. We connect our results to rule- and exemplar-based classification models. The pattern of influences of within- and between-category similarities are challenging for simple single-process categorization systems based on rules or exemplars. Instead, our results suggest that either these processes should be integrated in a hybrid model, or that category learning operates by forming clusters within each category. PMID:23403979

The effectiveness of group psychotherapy has been empirically studied and supported over several decades; however, there remains much to understand regarding the specific factors contributing to effective group psychotherapy. The current study uses Kashy and Kenny's (2000) actor-partner interdependence model (APIM) to examine the relationship between an individual group member's outcome and the outcomes of the other group members. This is the first study to examine the effects of the outcomes of other therapy group members on those of individual members. Specifically, we examined the relationship between an individual group member's presymptom score, the aggregated presymptom scores of the other group members, and the aggregated pre- to postsymptom change of the other group members on an individual group member's pre- to postsymptom change. We analyzed the change in pre-post posttraumatic stress disorder (PTSD) symptoms of 105 women in 16 trauma-informed groups in a women's correctional facility. As hypothesized, an individual's presymptom measure (actor effect) and the aggregated presymptom measures of the other group members (partner effect) were positively related to the individual's change in PTSD symptoms. Contrary to our hypothesis, the aggregated pre-post change in PTSD symptom measures of the other group members (partner effect) was negatively associated with the pre-post change in PTSD symptom measures of an individual group member. Social comparison theory is discussed as an explanation for why a group member would report lowered amounts of change when in a group with others who are reporting a higher amount of change. Implications for research and practice are discussed.

Reconstructing marginality: a new model of cultural diversity in nursing.

PubMed

Southwick, Margaret; Polaschek, Nick

2014-05-01

This article presents a new model of cultural diversity in nursing that critically reconstructs the concept of marginality that underpins other models. Rather than viewing the marginal as "other," marginality is redefined as the space in between the dominant cultural reality and the cultural realities of minority groups located within a society. Members of a minority cultural group who become skilled in the difficult process of negotiating this in-between space open the possibility of transformation within nursing education and practice. This model has been applied in a study of the experience of nursing students of Pacific ethnicity in New Zealand. Subsequently, an undergraduate Pacific nursing program was developed, with greatly increased success rates in registration of Pacific nurses. This model of cultural diversity can also be used to understand nursing practice involving people from minority cultures or other socially excluded categories. Copyright 2014, SLACK Incorporated.

HIV infection occurs in disproportionately high rates among racial and ethnic minorities in the United States, making it imperative that individuals from these groups be included in research studies. Unfortunately, it is often difficult to recruit HIV-infected Hispanics and African Americans into clinical trials, but a skilled interdisciplinary team that includes researchers with racial and ethnic diversity can help. This article describes a successful approach for building an interdisciplinary team that values the participation of racial and ethnic minorities in clinical trials and that has the skills to work with these groups. The success of the Adelante (a Spanish word meaning forward) Team can be attributed to team members who actively participate in decision-making, are empowered, and function in a cohesive manner. Successful research teams build relationships with research participants in order to increase the probability that racial and ethnic minorities will enroll and participate fully in research.

The Halobacteria constitute one of the largest groups within the Archaea. The hierarchical relationship among members of this large class, which comprises a single order and a single family, has proven difficult to determine based upon 16S rRNA gene trees and morphological and physiological characteristics. This work reports detailed phylogenetic and comparative genomic studies on >100 halobacterial (haloarchaeal) genomes containing representatives from 30 genera to investigate their evolutionary relationships. In phylogenetic trees reconstructed on the basis of 32 conserved proteins, using both neighbour-joining and maximum-likelihood methods, two major clades (clades A and B) encompassing nearly two-thirds of the sequenced haloarchaeal species were strongly supported. Clades grouping the same species/genera were also supported by the 16S rRNA gene trees and trees for several individual highly conserved proteins (RpoC, EF-Tu, UvrD, GyrA, EF-2/EF-G). In parallel, our comparative analyses of protein sequences from haloarchaeal genomes have identified numerous discrete molecular markers in the form of conserved signature indels (CSI) in protein sequences and conserved signature proteins (CSPs) that are found uniquely in specific groups of haloarchaea. Thirteen CSIs in proteins involved in diverse functions and 68 CSPs that are uniquely present in all or most genome-sequenced haloarchaea provide novel molecular means for distinguishing members of the class Halobacteria from all other prokaryotes. The members of clade A are distinguished from all other haloarchaea by the unique shared presence of two CSIs in the ribose operon protein and small GTP-binding protein and eight CSPs that are found specifically in members of this clade. Likewise, four CSIs in different proteins and five other CSPs are present uniquely in members of clade B and distinguish them from all other haloarchaea. Based upon their specific clustering in phylogenetic trees for different gene/protein sequences and the unique shared presence of large numbers of molecular signatures, members of clades A and B are indicated to be distinct from all other haloarchaea because of their uniquely shared evolutionary histories. Based upon these results, it is proposed that clades A and B be recognized as two new orders, Natrialbales ord. nov. and Haloferacales ord. nov., within the class Halobacteria, containing the novel families Natrialbaceae fam. nov. and Haloferacaceae fam. nov. Other members of the class Halobacteria that are not members of these two orders will remain part of the emended order Halobacteriales in an emended family Halobacteriaceae. © 2015 IUMS.

This paper explores the experience of disclosing HIV infection to family members. Information was obtained from secondary analysis of interviews conducted with 10 HIV-positive men and women. Learning that one is HIV-positive is a traumatic event, and disclosing this to family members can be difficult. Findings from this study suggest that family members generally overcome their own feelings and provide the infected individual with love and support. However, the resultant stress on the family may precipitate a crisis as secrets are brought into the open. Implications for nursing practice are addressed.

Seven focus groups comprising a total of 24 men and 14 women, with dysarthria or aphasia following stroke, who were members of VSS groups funded by Chest Heart and Stroke Scotland. We identified eight main themes. VSS groups (1) include members in an interpersonal network, (2) provide members with the opportunity to develop interpersonal relations, (3) provide members with support, (4) provide opportunities for personal growth and development, (5) supply members with a purpose, structure and routine, (6) help members establish and confirm their identify, beliefs and values, (7) help members accomplish individual and shared goals, and (8) provide members with the opportunity to influence others and be influenced. VSS groups appear to provide a range of functions that meet members' personal, interpersonal and psychological needs.

Plant P450s as versatile drivers for evolution of species-specific chemical diversity

PubMed Central

Hamberger, Björn; Bak, Søren

2013-01-01

The irreversible nature of reactions catalysed by P450s makes these enzymes landmarks in the evolution of plant metabolic pathways. Founding members of P450 families are often associated with general (i.e. primary) metabolic pathways, restricted to single copy or very few representatives, indicative of purifying selection. Recruitment of those and subsequent blooms into multi-member gene families generates genetic raw material for functional diversification, which is an inherent characteristic of specialized (i.e. secondary) metabolism. However, a growing number of highly specialized P450s from not only the CYP71 clan indicate substantial contribution of convergent and divergent evolution to the observed general and specialized metabolite diversity. We will discuss examples of how the genetic and functional diversification of plant P450s drives chemical diversity in light of plant evolution. Even though it is difficult to predict the function or substrate of a P450 based on sequence similarity, grouping with a family or subfamily in phylogenetic trees can indicate association with metabolism of particular classes of compounds. Examples will be given that focus on multi-member gene families of P450s involved in the metabolic routes of four classes of specialized metabolites: cyanogenic glucosides, glucosinolates, mono- to triterpenoids and phenylpropanoids.

Background Co-learning is one of the core principles of community-based participatory research (CBPR). Often, it is difficult to engage community members beyond those involved in the formal partnership in co-learning processes. However, to understand and address locally relevant root factors of health, it is essential to engage the broader community in participatory dialogues around these factors. Objective This article provides a glimpse into how using a photo-elicitation process allowed a community–academic partnership to engage community members in a participatory dialogue about root factors influencing health. The article details the decision to use photo-elicitation and describes the photo-elicitation method. Method Similar to a focus group process, photo-elicitation uses photographs and questions to prompt reflection and dialogue. Used in conjunction with an economic development framework, this method allows participants to discuss underlying, or root, community processes and structures that influence health. Conclusion Photo-elicitation is one way to engage community members in a participatory dialogue that stimulates action around root factors of health. To use this method successfully within a CBPR approach, it is important to build on existing relationships of trust among community and academic partners and create opportunities for community partners to determine the issues for discussion.

The Wallpaper Effect: The Contact Hypothesis Fails for Minority Group Members Who Live in Areas with a High Proportion of Majority Group Members

We aim to provide one explanation for why the link between contact and prejudice is consistently less strong for minority group members than it is for majority group members. Specifically, we propose a “wallpaper effect” such that contact works to increase minority group members' positivity towards majority groups when they live in areas densely populated with other minority group members. Conversely, we suggest that when minority group members live in neighborhoods patterned with majority group faces (as is so often the case), contact will be less transformative. We test this assumption using a large sample of both New Zealander minority (Māori; N = 925) and majority (European; N = 3805) group members. In line with predictions, Māori who lived in minority dense neighborhoods showed the traditional association between contact and increased warmth towards New Zealander Europeans. This relationship, however, was weak or non-existent when they lived in primarily European neighborhoods. Contact effects in majority group members were unaffected by neighborhood composition. The interaction held when controlling for, and was not explained by: gender, income, experiences of harm, cognitions of race-based rejection, or realistic threat. We provide the first evidence to suggest that when it comes to minority group members' intergroup attitudes, contact with majority group members may be a relatively ineffective predictor unless the “wallpaper” of their lives is minority-dense.

Specific sublingual immunotherapy (SLIT) has been proved to be a safe and effective approach in respiratory allergy. However, further research is required on aspects such as patient selection, use of optimal dosing, effects on asthma, long-term effects, and management of adverse reactions. In addition, the widely heterogeneous nature of studies on SLIT performed to date and the application of the criteria for subcutaneous immunotherapy make it difficult for the prescribing clinician to draw accurate and useful conclusions. Therefore, the QUASAR Group (QUality in the Administration of SLIT in Allergic Rhinitis), which comprises allergologists with broad clinical experience in SLIT, investigated the latest research findings and available data on this approach. Working parties were formed in 3 different categories: selection of candidates for SLIT, treatment efficacy, and adverse reactions. We performed a PubMed search for articles that were representative of each category and found 850. From these, we finally selected 266 articles, which were reviewed to retrieve data on SLIT. Evidence for each clinical question was graded according to the Oxford classification. The resulting text was evaluated on 3 occasions by all the members of the group until the final version was agreed upon. In this version, we review available evidence on SLIT, particularly with pollens, which is the subject of most articles. In areas where evidence is insufficient, an alternative agreed upon by the members of the QUASAR group is presented. Finally, we propose algorithms for selecting candidates for SLIT and for management of adverse events.

Continuous sedation at the end of life (CS) is the practice whereby a physician uses sedatives to reduce or take away a patient's consciousness until death. Although the incidence of CS is rising, as of yet little research has been conducted on how the administration of CS is experienced by medical practitioners. Existing research shows that many differences exist between medical practitioners regarding how and how often they perform CS. We conducted a focus group study to find out which factors may facilitate or constrain the use of continuous sedation by physicians and nurses. The participants often had clear ideas on what could affect the likelihood that sedation would be used. The physicians and nurses in the focus groups testified that the use of continuous sedation was facilitated in cases where a patient has a very limited life expectancy, suffers intensely, makes an explicit request and has family members who can cope with the stress that accompanies sedation. However, this 'paradigm case' was considered to occur only rarely. Furthermore, deviations from the paradigm case were said to be sometimes due to physicians initiating the discussion on CS too late or not initiating it at all for fear of inducing the patient. Deviations from the paradigm case may also occur when sedation proves to be too difficult for family members who are said to sometimes pressure the medical practitioners to increase dosages and speed up the sedation.

Sheffield Profile for Assessment and Referral for Care (SPARC) was developed in response to concerns that palliative care may not be reaching all people who could benefit from it. Acceptability of the tool is an important step in developing its future use. To elicit the views of a wide variety of members of consumer and self-help support groups concerned with health care on the relevance, acceptability and the overall perception of using SPARC as an early holistic needs assessment tool in supportive and palliative care. This study was conducted in South Yorkshire and North Derbyshire (UK). Ninety-nine consumer and self-help groups were identified from information in the public domain. Thirty-eight groups participated. Packs containing study information and self-complete postal questionnaires were distributed to groups, and they were asked to circulate these to their members. Completed questionnaires were returned in pre-paid envelopes to the research team. 135 questionnaires and feedback forms were returned. The majority of respondents found SPARC easy to understand (93% (120/129; 95% Confidence Interval 87% to 96%) and complete (94% (125/133; 95% CI: 88% to 97%). A minority, 12.2% (16/131), of respondents found questions on SPARC 'too sensitive'. Overall, respondents considered SPARC an acceptable and relevant tool for clinical assessment of supportive and palliative-care needs. Whilst a small minority of people found SPARC difficult to understand (i.e. patients with cognitive impairments), most categories of service user found it relevant. Clinical studies are necessary to establish the clinical utility of SPARC. © 2013 John Wiley & Sons Ltd.

Hand surgeons need continuing professional development due to rapid advancement in the field. Traditional approaches have proven to be challenging due to the nature of surgical practice and other demands. Social media sites have shown the potential to build an online community of practice. One of the authors (VR) started Hand Surgery International on LinkedIn in February 2011. The number of members increased from 38 in the beginning to 4106 members by August 13, 2015, with members from all over the world. Half of them are from plastic surgery, with 16.8% hand and 17.8% orthopedic surgery; 63.8% of them are consultants. There were 151 discussion topics, which generated 1238 comments at an average of 8.2 comments per discussion thread. The topics focused on management of difficult patients, seeking consensus, and searching information. The features participants found most useful included case-based discussion, polls/surveys, and network opportunity. Members perceived the LinkedIn community as user-friendly and easy to use. It does not require significant technical knowledge. For the question "How would you rate the overall ease of using this platform?" 42% answered "strongly agree" and 37% "agree". The LinkedIn group serves as an effective means for continuing professional development for hand surgeons. © 2015 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

In remote rural areas of Pakistan, access to the maternal, newborn and child health (MNCH) care provided by a skilled health provider is quite difficult. There are many reasons such as women's restricted social mobility, lack of education, disenfranchised in decision making and poverty. To overcome these barriers and impediments in district Chitral, which is the largest territory in terms of geography in province Khyber Pakhtunkhwa, local women of reproductive age, were mobilized to form the Community Based Saving Groups (CBSGs) at the village level. In these CBSGs, they pool-in their money, and then provide soft loans to the expecting mothers to meet the expenses of delivery. Simultaneously, young literate women were identified from the local communities; they were trained as Community Midwives (CMWs), using national MNCH curriculum, and later deployed in their respective villages within the district. This study captured their perceptions about the formation of CBSGs to overcome the financial and social barriers, and subsequent use of CMW services. A qualitative enquiry was conducted with the delivered mothers and their husbands through gender specific separate focus group discussions, with CBSG members and with non-members in four different sites of District Chitral. CBSG member women were far more aware on health issues. Information sought from these forums brought a noticeable change in the health seeking practices. Seeking care from a trained birth attendant in the community became easier. Women associated with the CBSGs as members, expressed an increased access to money for utilizing the CMW services, better awareness on MNCH issues, and empowerment to decide for seeking care. CBSG have been an instrumental platform for social networking, helping each other in other household matters. Women have started using the services of CMW and the CBSGs have actually helped them overcome the financial barriers in health care seeking. Moreover, the CBSGs became a medium to improve the awareness of service availability, understanding the MNCH issues, and timely utilization of MNCH services.

The BL Lac object 3C 66A is one of the most luminous extragalactic sources at TeV γ-rays (very high energy, i.e. E > 100 GeV). Since TeV γ-ray radiation is absorbed by the extragalactic background light (EBL), it is crucial to know the redshift of the source in order to reconstruct its original spectral energy distribution, as well as to constrain EBL models. However, the optical spectrum of this BL Lac is almost featureless, so a direct measurement of z is very difficult; in fact, the published redshift value for this source (z = 0.444) has been strongly questioned. Based on EBL absorption arguments, several constraints to its redshift, in the range 0.096 < z < 0.5, were proposed. Since these active galactic nuclei (AGNs) are hosted, typically, in early-type galaxies that are members of groups or clusters, we have analysed spectro-photometrically the environment of 3C 66A, with the goal of finding the galaxy group hosting this blazar. This study was made using optical images of a 5.5 × 5.5 arcmin2 field centred on the blazar, and spectra of 24 sources obtained with Gemini/GMOS-N multi-object spectroscopy. We found spectroscopic evidence of two galaxy groups along the blazar's line of sight: one at z ≃ 0.020 and the second one at z ≃ 0.340. The first one is consistent with a known foreground structure, while the second group presented here has six spectroscopically confirmed members. Their location along a red sequence in the colour-magnitude diagram allows us to identify 34 additional candidate members of the more distant group. The blazar's spectrum shows broad absorption features that we identify as arising in the intergalactic medium, thus allowing us to tentatively set a redshift lower limit at z_3C66A ≳ 0.33. As a consequence, we propose that 3C 66A is hosted in a galaxy that belongs to a cluster at z = 0.340.

An Acceptance-Based Psychoeducation Intervention to Reduce Expressed Emotion in Relatives of Bipolar Patients

PubMed Central

Eisner, Lori R.; Johnson, Sheri L.

2010-01-01

Expressed emotion (EE) is a robust predictor of outcome in bipolar disorder. Despite decades of research, interventions to reduce EE levels have had only modest effects. This study used an expanded model of EE to develop an intervention. Research has demonstrated a strong link between attributions and EE in families of patients with psychiatric disorders. There is also substantial research to suggest that anger can drive blaming attributions. Combining these ideas, this study built on previous psychoeducation interventions through the addition of an acceptance component designed to decrease anger and blaming attributions among family members of those with bipolar disorder. Twenty-eight family members attended a 1-day or 2-evening multifamily group workshop and completed a follow-up assessment 1 week later. At follow-up, participants demonstrated more knowledge about bipolar disorder. Anger, blaming attributions, and number of criticisms remained unchanged. Results of this study are consistent with others in that it is difficult to change EE. Implications for future clinical research in this area are addressed. PMID:19027434

The Stress Thermometer is an easily accessible Internet-based instrument for feedback on work stress and burnout. The aim of this paper is to describe the development of this instrument and to determine its applicability within the dental practice. The Stress Thermometer was made accessible to all members of the Dutch Dental Association, of which 77% of all Dutch dentists are members. Frequency of use was determined, and descriptive data was collected. During an evaluation period of 5 months at least 12% of all possible respondents made use of the Stress Thermometer. Descriptive characteristics of the response group, as well as levels of burnout and work stress, corresponded with those found in the Dutch dentist population. However, some deviations were also present. Results indicate the applicability of the Stress Thermometer to a representative variety of dentists. Although the deviations found should not be ignored in future use, the Stress Thermometer was successful in reaching a population that is difficult to reach. It effectively calls attention to sensitive personal issues concerning work-related stress and burnout.

Molecular phylogeny of Anopheles hyrcanus group (Diptera: Culicidae) based on mtDNA COI.

PubMed

Fang, Yuan; Shi, Wen-Qi; Zhang, Yi

2017-05-08

The Anopheles hyrcanus group, which includes at least 25 species, is widely distributed in the Oriental and Palearctic regions. Some group members have been incriminated as vectors of malaria and other mosquito-borne diseases. It is difficult to identify Hyrcanus Group members by morphological features. Thus, molecular phylogeny has been proposed as an important complementary method to traditional morphological taxonomy. Based on the GenBank database and our original study data, we used 466 mitochondrial DNA COI sequences belonging to 18 species to reconstruct the molecular phylogeny of the Hyrcanus Group across its worldwide geographic range. The results are as follows. 1) The average conspecific K2P divergence was 0.008 (range 0.002-0.017), whereas sequence divergence between congroup species averaged 0.064 (range 0.026-0.108). 2) The topology of COI tree of the Hyrcanus Group was generally consistent with classical morphological taxonomy in terms of species classification, but disagreed in subgroup division. In the COI tree, the group was divided into at least three main clusters. The first cluster contained An. nimpe; the second was composed of the Nigerrimus Subgroup and An. argyropus; and the third cluster was comprised of the Lesteri Subgroup and other unassociated species. 3) Phylogenetic analysis of COI indicated that ancient hybridizations probably occurred among the three closely related species, An. sinensis, An. belenrae, and An. kleini. 4) The results supported An. paraliae as a probable synonym of An. lesteri, and it was possible that An. pseudopictus and An. hyrcanus were the same species, as evident from their extremely low interspecific genetic divergence (0.020 and 0.007, respectively) and their phylogenetic positions. In summary, we reconstructed the molecular phylogeny and analysed genetic divergence of the Hyrcanus Group using mitochondrial COI sequences. Our results suggest that in the future of malaria surveillance, we should not only pay much attention to those known vectors of malaria, but also their closely related species.

Impact of centrality on cooperative processes

NASA Astrophysics Data System (ADS)

Reia, Sandro M.; Herrmann, Sebastian; Fontanari, José F.

2017-02-01

The solution of today's complex problems requires the grouping of task forces whose members are usually connected remotely over long physical distances and different time zones. Hence, understanding the effects of imposed communication patterns (i.e., who can communicate with whom) on group performance is important. Here we use an agent-based model to explore the influence of the betweenness centrality of the nodes on the time the group requires to find the global maxima of NK-fitness landscapes. The agents cooperate by broadcasting messages, informing on their fitness to their neighbors, and use this information to copy the more successful agents in their neighborhood. We find that for easy tasks (smooth landscapes), the topology of the communication network has no effect on the performance of the group, and that the more central nodes are the most likely to find the global maximum first. For difficult tasks (rugged landscapes), however, we find a positive correlation between the variance of the betweenness among the network nodes and the group performance. For these tasks, the performances of individual nodes are strongly influenced by the agents' dispositions to cooperate and by the particular realizations of the rugged landscapes.

The genesis of 'the Neophytes': a writing support group for clinical nurses.

PubMed

Stone, Teresa; Levett-Jones, Tracy; Harris, Margaret; Sinclair, Peter M

2010-10-01

This paper profiles the establishment and evaluation of the Neophyte Writers' Group, run by nurse academics in collaboration with clinical nurses. The growing demand for nurses to write, publish and present their work had inspired the introduction of a series of workshops designed to develop and improve writing and presentation skills, which eventuated in formation of the Neophytes. The group was founded on the basis of Bandura's theory of self-efficacy (1997), a concept which has been discussed extensively in social psychology literature to explain motivation and learning theory. People with high assurance in their capabilities regard difficult tasks as challenges to be mastered rather than as threats to be avoided (Bandura, 1994). The Neophytes' group employs a collaborative approach intended to increase and reinforce members' self-confidence; the underlying philosophy is to promote and enhance writers' motivation, capacity and self-efficacy in order to achieve future publication goals confidently and independently. Support which engenders these strengths through a program relevant to participants' needs is likely, as this group found, to increase publication productivity. Additional unexpected outcomes resulted, such as engagement by clinical nurses' in academic work, and an increase in research higher degree enrolments. Copyright © 2010 Elsevier Ltd.

Clinical trials oversight by a Trial Steering Committee (TSC) is mandated by Good Clinical Practice. This study used qualitative methods to explore the role and valued attributes of the TSC to inform planned updates of Medical Research Council guidance and TSC terms of reference. An ethnographic study was conducted during 2013-2014. TSC and Trial Management Group meetings from eight trials were observed and audio-recorded, and semi-structured interviews conducted with purposively sampled key informants: independent and non-independent TSC members, trial sponsor representatives, funder representatives and chief investigators. The selected trials were currently recruiting and dealing with challenging scenarios. Data were analysed thematically and findings triangulated and integrated to give a multi-perspective account of the role and valued attributes of a TSC. Eight TSC meetings and six Trial Management Group meetings were observed. Sixty-five interviews were conducted with 51 informants. The two main roles played by the TSC were quality assurance and patient advocacy. Quality assurance involved being a 'critical friend' or a provider of 'tough love'. Factors influencing the ability of the TSC to fulfil this role included the TSC Chair, other independent TSC members and the model of the TSC and its fit with the trial subject. The role of the TSC as an advocate for patient well-being was perceived as paramount. Two attributes of TSC members emerged as critical: experience (of running a trial, trial oversight or in a clinical/methodological area) and independence. While independence was valued for giving impartiality, the lack of consensus about its definition and strict requirements of some funders made it difficult to operationalise. We found tensions and ambiguities in the roles expected of TSCs and the attributes valued of TSC members. In particular, the requirements of independence and experience could conflict, impacting the TSCs' quality assurance role. Concerns were raised regarding whose interests are served by funders' criteria of independence; in particular, funders' selection of TSC members was thought to potentially inhibit TSCs' ability to fulfil their patient advocacy role. These findings should be incorporated in revising guidance and terms of reference for TSCs.

People face many challenging psychosocial and spiritual issues as they approach the end of their lives, and caregivers need advice on how to help them. Choosing among treatment options, handling grief, addressing unfinished business, and coping with loss of self-sufficiency are difficult for the dying person, and caregivers must deal with surrogate decision making, raw emotions in the patient and in family members, and the caregivers' own grief. Listening and coping skills are discussed.

AIM: To investigate the treatment strategies and long-term outcomes of radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) in difficult locations and to compare the results with non-difficult HCC. METHODS: From 2004 to 2012, a total of 470 HCC patients underwent ultrasound-guided percutaneous RFA. Among these HCC patients, 382 with tumors located ≤ 5 mm from a major vessel/bile duct (n = 87), from peripheral important structures (n = 232) or from the liver capsule (n = 63) were regarded as difficult cases. There were 331 male patients and 51 female patients, with an average age of 55.3 ± 10.1 years old. A total of 235 and 147 patients had Child-Pugh class A and class B liver function, respectively. The average tumor size was 3.4 ± 1.2 cm. Individual treatment strategies were developed to treat these difficult cases. During the same period, 88 HCC patients with tumors that were not in difficult locations served as the control group. In the control group, 74 patients were male, and 14 patients were female, with an average age of 57.4 ± 11.8 years old. Of these, 62 patients and 26 patients had Child-Pugh class A and class B liver function, respectively. Regular follow-up after RFA was performed to assess treatment efficacy. Survival results were generated from Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression model. RESULTS: Early tumor necrosis rate in the difficult group was similar to that in the control group (97.6% vs 94.3%, P = 0.080). The complication rate in the difficult group was significantly higher than that in the control group (4.9% vs 0.8%, P = 0.041). The follow-up period ranged from 6 to 116 mo, with an average of 28 ± 22.4 mo. Local progression rate in the difficult group was significantly higher than that in the control group (12.7% vs 7.1%, P = 0.046). However, the 1-, 3-, 5-, and 7-year overall survival rates in the difficult group were not significantly different from those in the control group (84.3%, 54.4%, 41.2%, and 29.9% vs 92.5%, 60.3%, 43.2%, and 32.8%, respectively, P = 0.371). Additionally, a multivariate analysis revealed that tumor location was not a significant risk factor for survival. CONCLUSION: There was no significant difference in long-term overall survival between the two groups even though the local progression rate was higher in the difficult group. PMID:25663774

Keeping up appearances: Strategic information exchange by disidentified group members

PubMed Central

Matschke, Christina

2017-01-01

Information exchange is a crucial process in groups, but to date, no one has systematically examined how a group member’s relationship with a group can undermine this process. The current research examined whether disidentified group members (i.e., members who have a negative relationship with their group) strategically undermine the group outcome in information exchange. Disidentification has been found to predict negative group-directed behaviour, but at the same time disidentified members run the risk of being punished or excluded from the group when displaying destructive behaviour. In three studies we expected and found that disidentified group members subtly act against the interest of the group by withholding important private information, while at the same time they keep up appearances by sharing important information that is already known by the other group members. These findings stress the importance of taking a group member’s relationship with a group into account when considering the process of information exchange. PMID:28384322

Ethnic minority patients have unique challenges in accessing health services. These include language difficulties, unfamiliarity with the health system, lower rates of cancer screening and survival, higher rates of reported side effects from cancer treatment and poorer quality of life. Little is known about this patient group when transitioning to palliative care. To elicit the experiences of palliative care health professionals when providing care for patients from culturally and linguistically diverse backgrounds which differ from mainstream Australian language and culture. An emergent qualitative design, informed by theoretical and procedural direction from grounded theory research. Four focus groups held with palliative care staff ( n = 28) in a single specialist palliative care service in Australia. The following themes emerged: (1) determining the rules of engagement around discussion of diagnosis and prognosis, (2) navigating the challenge of language to patient understanding, (3) understanding migration experiences to establish trust, (4) maintaining the balance between patient safety and comfort care, (5) providing a good death experience through accommodation of beliefs, and (6) navigating the important role of family members while privileging patient preferences. Underlying provider perceptions of caring for patients was that death is difficult in any language. Care was conceptualised as considering cultural and linguistic backgrounds within individualistic care. Understanding the migration experience and building trust were key elements of this individualised approach. Acknowledgement of the key role played by families in patient care and safety are strategies to minimise barriers and understand the concerns of this patient group.

Group members' questions shape participation in health counselling and health education.

Logren, Aija; Ruusuvuori, Johanna; Laitinen, Jaana

2017-10-01

This study examines how group members' questions shape member participation in health counselling and health education groups. The study applies conversation analytic principles as a method. The data consist of video-recorded health education lessons in secondary school and health counselling sessions for adults with a high risk of Type 2 diabetes. Group members' questions accomplish a temporary change in participatory roles. They are used to 1) request counselling, 2) do counselling or 3) challenge previous talk. They are usually treated as relevant and legitimate actions by the participants, but are occasionally interpreted as transitions outside the current action or topic. Group members' questions result in a shift from leader-driven to member-driven discussion. Thus they constitute a pivot point for detecting changes in participation in group interventions. Observing the occurrence of group members' questions helps group leaders to adjust their own actions accordingly and thus facilitate or guide group participation. Comparison of the type and frequency of members' questions is a way to detect different trajectories for delivering group interventions and can thus be used to develop methods for process evaluation of interventions.

Group members differ in relative prototypicality: Effects on the individual and the group.

PubMed

Hogg, Michael A

2016-01-01

All groups are differentiated into more or less group-prototypical members. Central members readily influence and lead the group, and they define its identity. Peripheral members can feel voiceless and marginalized, as well as uncertain about their membership status - they may engage in extreme behaviors to try to win acceptance. These relative prototypicality dynamics sometimes benefit group performance but sometimes compromise performance.

Cognitive synergy in groups and group-to-individual transfer of decision-making competencies

2015-01-01

In a field study (148 participants organized in 38 groups) we tested the effect of group synergy and one's position in relation to the collaborative zone of proximal development (CZPD) on the change of individual decision-making competencies. We used two parallel sets of decision tasks reported in previous research to test rationality and we evaluated individual decision-making competencies in the pre-group and post-group conditions as well as group rationality (as an emergent group level phenomenon). We used multilevel modeling to analyze the data and the results showed that members of synergetic groups had a higher cognitive gain as compared to members of non-synergetic groups, while highly rational members (members above the CZPD) had lower cognitive gains compared to less rational group members (members situated below the CZPD). These insights extend the literature on group-to-individual transfer of learning and have important practical implications as they show that group dynamics influence the development of individual decision-making competencies.

2003-03-01

Two experiments investigated the tendency of groups with members under high (vs. low) need for cognitive closure to develop an autocratic leadership structure in which some members dominate the discussion, constitute the "hubs" of communication, and influence the group more than other members. The first experiment found that high (vs. low) need for closure groups, as assessed via dispositional measure of the need for closure, manifested greater asymmetry of conversational floor control, such that members with autocratic interactional style were more conversationally dominant and influential than less autocratic members. The second experiment manipulated the need for closure via time pressure and utilized a social network analysis. Consistent with expectation, groups under time pressure (vs. no pressure) showed a greater asymmetry of participation, of centrality, and of prestige among the group members, such that the more focal members were perceived to exert the greater influence over the groups' decisions.

2017-01-01

To understand technical nursing students' meaning of interacting with family members of hospitalized children. Symbolic Interactionism was used as the theoretical framework and Qualitative Content Analysis was the methodological procedure. A total of eight graduates from an institution situated in the city of Osasco, Sao Paulo state, participated in this study. Data were collected through semi-structured interviews. A total of five representative themes were revealed: Dealing with difficult situations with family members; Perceiving oneself to be unprepared to interact with family members; Family members being a helpful tool; Developing strategies to obtain a good interaction with family members; and Teachers being facilitators of the interaction with family members. To be acquainted with this experience has led to the understanding of the need to include the theme of family care in the curriculum of the Technical Nursing Course. Additionally, the present study contributed to reflections on the importance of such knowledge for this population and to the development of future studies, as this theme has been scarcely explored in the literature.

The systematics and evolution of New World primates - A review.

PubMed

Schneider, Horacio; Sampaio, Iracilda

2015-01-01

This paper provides an overview of the taxonomy of New World primates from proposals of the 1980's based on morphology to the great number of studies based on molecular data aiming for the elucidation of the phylogeny of New World monkeys. The innovations of the first molecular phylogeny presented by Schneider et al. (1993) positioned Callimico as a sister group of Callithrix and Cebuella; Callicebus as a member of the pitheciids; Brachyteles as sister to Lagothrix; and the night monkeys (Aotus), capuchins (Cebus) and squirrel monkeys (Saimiri) in the same clade with the small callitrichines. These results were subsequently confirmed by dozens of subsequent studies using data from DNA sequences. Some issues difficult to resolve with the phylogenetic analyses of DNA sequences, such as the diversification of the oldest lineages (pitheciids, atelids and cebids), and the confirmation of Aotus as a member of the Cebinae clade (together with Cebus/Saimiri), were clarified with new molecular approaches based on the presence or absence of Alu insertions as well as through the use of phylogenomics. At this time, all relationships at the intergeneric level had been deciphered, with the exception of the definition of the sister group of callitrichines (whether Aotus or Cebus/Saimiri are sister to callitrichines, or if Aotus, Saimiri and Cebus form a clade together). Future studies should prioritize the alpha taxonomy of most Neotropical primate groups, and the use of phylogenetic and geographic data, combined with reliable estimates of divergence times, to clarify the taxonomic status at species and genus level, as well as to help understand the evolutionary history of this remarkable and highly diversified group.

Rh(V) -Nitrenoid as a Key Intermediate in Rh(III) -Catalyzed Heterocyclization by C-H Activation: A Computational Perspective on the Cycloaddition of Benzamide and Diazo Compounds.

PubMed

Zhou, Tao; Guo, Wei; Xia, Yuanzhi

2015-06-15

A mechanistic study of the substituent-dependent ring formations in Rh(III) -catalyzed C-H activation/cycloaddition of benzamide and diazo compounds was carried out by using DFT calculations. The results indicated that the decomposition of the diazo is facilitated upon the formation of the five-membered rhodacycle, in which the Rh(III) center is more electrophilic. The insertion of carbenoid into Rh-C(phenyl) bond occurs readily and forms a 6-membered rhodacycle, however, the following C-N bond formation is difficult both kinetically and thermodynamically by reductive elimination from the Rh(III) species. Instead, the Rh(V) -nitrenoid intermediate could be formed by migration of the pivalate from N to Rh, which undergoes the heterocyclization much more easily and complementary ring-formations could be modulated by the nature of the substituent at the α-carbon. When a vinyl is attached, the stepwise 1,3-allylic migration occurs prior to the pivalate migration and the 8-membered ring product will be formed. On the other hand, the pivalate migration becomes more favorable for the phenyl-contained intermediate because of the difficult 1,3-allylic migration accompanied by dearomatization, thus the 5-membered ring product was formed selectively. © 2015 WILEY-VCH Verlag GmbH & Co.

Although some family histories are clear with multiple members affected, other families require directed inquiry. Second, even when a hereditary neuropathy is clear, it can be difficult to make a genetic characterization. The field of genotyping is expanding so rapidly, it is difficult to know what tests to order.

Although clinical researchers have applied attachment theory to client conceptualization and treatment in individual therapy, few researchers have applied this theory to group therapy. The purpose of this article is to begin to apply theory and research on adult dyadic and group attachment styles to our understanding of group dynamics and processes in adult therapy groups. In particular, we set forth theoretical propositions on how group members' attachment styles affect relationships within the group. Specifically, this article offers some predictions on how identifying group member dyadic and group attachment styles could help leaders predict member transference within the therapy group. Implications of group member attachment for the selection and composition of a group and the different group stages are discussed. Recommendations for group clinicians and researchers are offered.

The Enforcement of Moral Boundaries Promotes Cooperation and Prosocial Behavior in Groups

Simpson, Brent; Willer, Robb; Harrell, Ashley

2017-01-01

The threat of free-riding makes the marshalling of cooperation from group members a fundamental challenge of social life. Where classical social science theory saw the enforcement of moral boundaries as a critical way by which group members regulate one another’s self-interest and build cooperation, moral judgments have most often been studied as processes internal to individuals. Here we investigate how the interpersonal expression of positive and negative moral judgments encourages cooperation in groups and prosocial behavior between group members. In a laboratory experiment, groups whose members could make moral judgments achieved greater cooperation than groups with no capacity to sanction, levels comparable to those of groups featuring costly material sanctions. In addition, members of moral judgment groups subsequently showed more interpersonal trust, trustworthiness, and generosity than all other groups. These findings extend prior work on peer enforcement, highlighting how the enforcement of moral boundaries offers an efficient solution to cooperation problems and promotes prosocial behavior between group members.

This study examined the role of an online workspace component of a community in the work of a community of practice. Much has been studied revealing the importance of communities of practice to organizations, project success, and knowledge management and some of these same successes hold true for virtual communities of practice. Study participants were 75 Education and Public Outreach community members of NASA's Science Mission Directorate Earth Forum. In this mixed methods study, online workspace metrics were used to track participation and a survey completed by 21 members was used to quantify participation. For a more detailed analysis, 15 community members (5 highly active users, 5 average users, and 5 infrequent users) selected based on survey responses, were interviewed. Finally, survey data was gathered from 7 online facilitators to understand their role in the community. Data collected from these 21 community members and 5 facilitating members suggest that highly active users (logging into the workspace daily), were more likely to have transformative experiences, co-create knowledge, feel ownership of community knowledge, have extended opportunities for community exchange, and find new forms of evaluation. Average users shared some similar characteristics with both the highly active members and infrequent users, representing a group in transition as they become more engaged and active in the online workspace. Inactive users viewed the workspace as having little value, being difficult to navigate, being mainly for gaining basic information about events and community news, and as another demand on their time. Results show the online workspace component of the Earth Science Education and Outreach Forum is playing an important and emerging role for this community by supporting knowledge building and knowledge sharing, and growing in value for those that utilizing it more frequently. The evidence suggests that with increased participation or "usage" comes increased value to the participant and the organization. This research illustrates the possible change in mindset held by participating community members when it comes to the nature of co-location. Additionally, it may be of particular importance in exploring changes in the community members' feelings of connection and belonging.

A personal learning project (PLP) is an accredited form of Continuing Professional Development (CPD) in Canada, and is a self-initiated learning activity that is stimulated by a question, issue or dilemma in one's professional practice. Many complex cases or issues have no answers that are readily available. Many physicians rely day to day on other physician colleagues that they may consult in their institution. Given the paucity of same specialty Physical Medicine and Rehabilitation colleagues in Canadian centres, the idea of Virtual Spinal Cord Injury (SCI) Hallway germinated, to provide a simple tool to extend our hallways to reach colleagues with similar interests across the country. The Virtual SCI Hallway is a service set up on Yahoo Groups, with no cost to the users. On this invite-only site, members may post a question, and then all members receive the post by email. Any member may respond. The SCI Hallway has been running successfully for over 13 years. As of January 2017, there were 38 members, with 2124 messages within approximately 324 conversations. Activity has been consistent since 2003. Questions and posts are not always medical expert related; there are also advocacy, professional, and scholar-role related posts. Communication amongst specialists about practice and management of complicated problems is important for CPD, yet is difficult in subspecialized areas of medicine. Although there are many chat-pages in different areas of medicine on the internet, to our knowledge, there is not another secure, invite-only site that is low-maintenance and no cost.

Cooperation during cultural group formation promotes trust towards members of out-groups.

People often cooperate with members of their own group, and discriminate against members of other groups. Previous research establishes that cultural groups can form endogenously, and that these groups demonstrate in-group favouritism. Given the presence of cultural groups, the previous literature argues that cultural evolution selects for groups that exhibit parochial altruism. The source of initial variation in these traits, however, remains uninformed. We show here that a group's economic production environment may substantially influence parochial tendencies, with groups formed around more cooperative production (CP) displaying less parochialism than groups formed around more independent production (IP) processes. Participants randomized into CP and IP production tasks formed cultural groups, and subsequently played hidden-action trust games with in-group and out-group trustees. We found CP to be associated with significantly greater sharing and exchanging behaviours than IP. In trust games, significant parochial altruism (in-group favouritism combined with out-group discrimination) was displayed by members of IP groups. By contrast, members of CP groups did not engage in either in-group favouritism or out-group discrimination. Further, we found the absence of out-group discrimination in CP to persist even following 'betrayal'. Finally, belief data suggest that members of CP are not more intrinsically generous than IP members, but rather more likely to believe that out-group trustees will positively reciprocate. Our results have important implications for anyone interested in building cooperative teams, and shed new light on connections between culture and cooperation.

Social identity shapes social valuation: evidence from prosocial behavior and vicarious reward.

People frequently engage in more prosocial behavior toward members of their own groups, as compared to other groups. Such group-based prosociality may reflect either strategic considerations concerning one's own future outcomes or intrinsic value placed on the outcomes of in-group members. In a functional magnetic resonance imaging experiment, we examined vicarious reward responses to witnessing the monetary gains of in-group and out-group members, as well as prosocial behavior towards both types of individuals. We found that individuals' investment in their group-a motivational component of social identification-tracked the intensity of their responses in ventral striatum to in-group (vs out-group) members' rewards, as well as their tendency towards group-based prosociality. Individuals with strong motivational investment in their group preferred rewards for an in-group member, whereas individuals with low investment preferred rewards for an out-group member. These findings suggest that the motivational importance of social identity-beyond mere similarity to group members-influences vicarious reward and prosocial behavior. More broadly, these findings support a theoretical framework in which salient social identities can influence neural representations of subjective value, and suggest that social preferences can best be understood by examining the identity contexts in which they unfold. © The Author (2017).

Every public speaker has encountered, or most likely will encounter, a difficult member of the audience who disrupts their presentation. This is a source of anxiety and discomfort, not only for the presenter, but for the audience as well. Learning how to manage the disruptive audience member is an art form, just like being a good public speaker. A professional speaker knows how to handle this disruption without making the audience uncomfortable and without embarrassing the disruptor. This article discusses ways to manage the disruptive audience member and will help those of you who do public speaking to tactfully and professionally disengage someone who is ruining your program.

We aimed to provide process and effectiveness evaluations of a sex education intervention realized with interactive techniques in high schools of Pavia (Italy). Six public high schools, divided into 'treated' and 'control' units, voluntarily joined this mixed-methods study. Only second-year classes were enrolled: treated adolescents followed a sex education course, performed by trained 'near-peer educators' (undergraduate medical students) with interactive techniques. All adolescents compiled an anonymous effectiveness evaluation questionnaire at baseline (pre-test) and 3 months later (post-test). Sexual knowledge and reported behavioural changes were compared between the two groups through linear mixed-effects models. The process was assessed through a satisfaction questionnaire for treated students, monitoring cards for working group members and cards/diaries for educators. The final sample consisted of 547 treated and 355 control adolescents (mean age = 15.28 ± 0.61 years). Highly significant changes (p < 0.001) from pre-test to post-test, with strong improvements of treated adolescents, were evident for all knowledge items. No significant changes for behavioural items were reported. Process evaluation showed positive results in adolescents' satisfaction, highlighting the need for more youth gathering places. Working group members and educators generally provided positive evaluations, although difficult communication was perceived. The intervention was effective in improving adolescents' sexual knowledge. The present work highlighted that in Italy sex education in adolescence is still neglected: this could encourage misinformation and health-risk behaviour. Young people perceive the need for a serious health-promoting action in which they could play an active role, spreading educational messages with organized interactive methods. © The Author(s) 2015.

Membership status and subjective group dynamics: who triggers the black sheep effect?

Pinto, Isabel R; Marques, José M; Levine, John M; Abrams, Dominic

2010-07-01

In 3 experiments, participants (Ns = 50, 95, and 75, respectively) judged 2 ingroup or outgroup members who occupied 1 of 3 statuses--new members, full members, or marginal members. In each case, 1 of these members adopted a normative position and another supported a deviant position regarding a relevant issue. Participants upgraded normative ingroup full members and derogated deviant ingroup full members compared with all other members. In addition, derogation of deviant ingroup members was associated with a socializing and a punishing intention toward new members and full members, respectively. These results are discussed in terms of the group socialization model (e.g., Levine & Moreland, 1994) and the subjective group dynamics model (e.g., Marques, Paez, & Abrams, 1998).

2013-11-01

Over half of general anesthetics in the UK involve supraglottic airway devices (SADs). The National Audit Project 4 undertaken by the Royal College of Anaesthetists demonstrated that aspiration was the most frequent complication relating to SAD use. SADs designed to reduce this risk (second-generation devices) are increasingly recommended in both adults and children. As well as routine use, SADs are recommended for use in cases of 'difficult airway'. This survey assessed current usage of SADs in routine practice and difficult airways. Sixteen questions, approved by the Association of Paediatric Anaesthetists of Great Britain and Ireland (APAGBI) survey committee, were distributed to all its members. Two hundred and forty-four members responded. Eighty-eight percent preferentially use first-generation rather than second-generation devices. The most important design feature was the availability of a complete range of sizes (84%). Seventy-seven percent felt that randomized controlled trials assessing SAD safety in children are needed. In cases of failed intubation, classically shaped SADs are preferred (79%). Three percent of responders intubate via an SAD routinely. Eighteen percent have employed this technique in an emergency. Thirty-six percent of responders have found an SAD to function poorly. Pediatric anesthesiologists appear slow to embrace second-generation SADs. The role of SADs in the management of difficult airways is widely accepted. Research currently has little influence over the choice of which SAD to use, which is more likely determined by personal choice and departmental preference. There is a risk that some SADs are unsafe. © 2013 John Wiley & Sons Ltd.

Current Understanding of Ecdysozoa and its Internal Phylogenetic Relationships.

Giribet, Gonzalo; Edgecombe, Gregory D

2017-09-01

Twenty years after its proposal, the monophyly of molting protostomes-Ecdysozoa-is a well-corroborated hypothesis, but the interrelationships of its major subclades are more ambiguous than is commonly appreciated. Morphological and molecular support for arthropods, onychophorans and tardigrades as a clade (Panarthropoda) continues to be challenged by a grouping of tardigrades with Nematoida in some molecular analyses, although onychophorans are consistently recovered as the sister group of arthropods. The status of Cycloneuralia and Scalidophora, each proposed by morphologists in the 1990s and widely employed in textbooks, is in flux: Cycloneuralia is typically non-monophyletic in molecular analyses, and Scalidophora is either contradicted or incompletely tested because of limited genomic and transcriptomic data for Loricifera, Kinorhyncha, and Priapulida. However, novel genomic data across Ecdysozoa should soon be available to tackle these difficult phylogenetic questions. The Cambrian fossil record indicates crown-group members of various ecdysozoan phyla as well as stem-group taxa that assist with reconstructing the most recent common ancestor of panarthropods and cycloneuralians. © The Author 2017.

The Name-Letter-Effect in Groups: Sharing Initials with Group Members Increases the Quality of Group Work

2013-01-01

Although the name-letter-effect has been demonstrated reliably in choice contexts, recent research has called into question the existence of the name-letter-effect–the tendency among people to make choices that bear remarkable similarity with the letters in their own name. In this paper, we propose a connection between the name-letter-effect and interpersonal, group-level behavior that has not been previously captured in the literature. Specifically, we suggest that sharing initials with other group members promotes positive feelings toward those group members that in turn affect group outcomes. Using both field and laboratory studies, we found that sharing initials with group members cause groups to perform better by demonstrating greater performance, collective efficacy, adaptive conflict, and accuracy (on a hidden-profile task). Although many studies have investigated the effects of member similarity on various outcomes, our research demonstrates how minimal a degree of similarity among members is sufficient to influence quality of group outcomes.

The communication of social stereotypes: the effects of group discussion and information distribution on stereotypic appraisals.

PubMed

Brauer, M; Judd, C M; Jacquelin, V

2001-09-01

Stereotypes are fundamentally social constructs, formulated and modified through discussion and interaction with others. The present studies examined the impact of group discussion on stereotypes. In both studies, groups of participants discussed their impressions about a hypothetical target group after having read behaviors performed by target group members. These behaviors included both stereotypic and counterstereotypic examples, and the distribution of these behaviors varied across discussion group members. In some groups only 1 member knew of the counterstereotypic behaviors; in other groups this information was distributed across all group members. In general, discussion led to a polarization of the target group stereotypes, but this effect was lessened when the counterstereotypic behaviors were concentrated in 1 group member. In this case, these counterstereotypic behaviors were discussed more and retained better.

Risk-adjusted outcome data for general surgeons practicing in the United Kingdom were published for the first time in 2013 with the aim of increasing transparency, improving standards, and providing the public with information to aid decision making. Most specialties used funnel plots to present their data. We assess the ability of members of the public (MoP), medical students, nonsurgical doctors (NSD), and surgeons to understand risk-adjusted surgical outcome data. A fictitious outcome dataset was created and presented in the form of a funnel plot to 10 participants from each of the aforementioned group. Standard explanatory text was provided. Each participant was given 5 minutes to review the funnel plot and complete a questionnaire. For each question, there was only 1 correct answer. Completion rate was 100% (n = 40). No difference existed between NSD and surgeons. A significant difference for identification of the "worst performing surgeon" was noted between surgeons and MoP (p < 0.01) and between NSD and MoP (p < 0.01). Half of medical students and MoP claimed they would use this information to aid decision making compared with 80% of doctors. MoP reported the funnel plot significantly "more difficult" to interpret than surgeons did (p < 0.01) and NSD (p < 0.01). MoP found these data significantly more "difficult to understand" and were less likely to both spot "outliers" and use this data to inform decisions than doctors. Surgeons should be aware that outcome data may require an alternative method of presentation to be understood by MoP. Copyright © 2015 Association of Program Directors in Surgery.

The prevalence of antibodies to pancreatic islets in monogenic diabetes remains unknown and the incidence estimation is difficult as the occurrence of autoantibodies in patient is one of the well-known exclusion criteria for further genetic diagnostics. They has been found not only among patients with type 1 diabetes, but also in other types of diabetes: Type 2 diabetes, Latent Autoimmune Diabetes in Adults (LADA) (16) and monogenic diabetes (MD). Immunological characteristic of GCK MODY patients. The study group included families of 27 adolescent patients with GCK MODY (39 parents and 19 siblings) monitored in the Department of Pediatrics, Endocrinology and Diabetes and in the Diabetes Clinic of John Paul II Upper Silesian Child Health Centre in Katowice in the years 2007-2012. All patients and family members with GCK MODY underwent a blood sample drawing for immunological (classic humoral response markers: ICA, GAD, IA-2, IAA) and biochemical diagnostics. Pediatric, diabetes and family medical history was collected from the subjects and parents. Immunological diagnostics was performed in all patients except 1 (96.3%). Immunological diagnostics included 17 (89.5%) parents and 7 (87.5%) siblings with diagnosed GCK MODY. 8 (30.8%) adolescent patients with GCK MODY, 3 subjects (17.64%) among parents (with GCK MODY), as well as 2 subjects (28.57%) among siblings (with GCK MODY) showed a positive antibodies screen. The results of our study in children with GCK MODY and their family members suggest that the occurrence of classic antibodies directed against pancreatic islets antigens is fairly common in patients with GCK MODY. Despite various observations and many legitimate discussions, it is difficult to clarify the pathogenesis of the occurrence of autoantibodies in monogenic diabetes. © Polish Society for Pediatric Endocrinology and Diabetology.

There is a need for scholars to be prepared as peer reviewers in order to ensure the continual publication of quality science. However, developing the skills to craft a constructive critique can be difficult. In this commentary, we discuss the use of a group peer review mentoring model for PhD students to gain experience in peer review from a faculty member who is experienced in peer review. Central to this model, was the opportunity for each student and faculty mentor to openly discuss their critique of the manuscript. Through this enriching experience, novice researchers were able to learn the elements of a good peer review, better determine a manuscript's substantive contribution to science, and advance the quality of their own manuscript writing.

Etiological Theories of Adolescent Idiopathic Scoliosis: Past and Present

PubMed Central

Fadzan, Maja; Bettany-Saltikov, Josette

2017-01-01

Adolescent idiopathic scoliosis is one of the most common spinal deformities, yet its cause is unknown. Various theories look to biomechanical, neuromuscular, genetic, and environmental origins, yet our understanding of scoliosis etiology is still limited. Determining the cause of a disease is crucial to developing the most effective treatment. Associations made with scoliosis do not necessarily point to causality, and it is difficult to determine whether said associations are primary (playing a role in development) or secondary (develop as a result of scoliosis). Scoliosis is a complex condition with highly variable expression, even among family members, and likely has many causes. These causes could be similar among homogenous groups of AIS patients, or they could be individual. Here, we review the most prevalent theories of scoliosis etiology and recent trends in research.

This study examines the development of collaborative relationships between family physicians (FPs) and Anticipatory And Preventative Team Care (APTCare) team members providing care to medically complex patients who have been identified as at-risk for negative health outcomes. We undertook a qualitative study of a primary health care intervention in a family practice. Interviews were held with FPs and ATPCare intervention nurse practitioners (NPs) and pharmacists. Focus groups were conducted and a survey was administered to participating FPs, NPs, and pharmacists. NPs and pharmacists maintained a log recording their tasks and moments of collaboration. Scheduling demands rendered face-to-face collaboration difficult, leaving the team to rely on technological tools to keep in touch. Limited space meant the APTCare team had to work out of a downstairs office, limiting informal interactions with the practitioners on the main level. We demonstrate that the difficulties inherent in collaborative care are independent of the patient population being cared for. Regardless of the patient population and sector of health care, developing collaborative relationships and learning to work collaboratively is difficult and takes time. What many of these teams need is ongoing support and education about how to make these collaborative care practices work.

The aim of this study was to describe the specific engineering services and suitability of candidates for the psychophysical performance. Navy ships are equipped with equipment and weapons are controlled by electronic devices ship and crew. Advanced technology puts high demands on operator. For the ship's staff are recruited soldiers of the psychophysical characteristics predisposing to this kind of action. The paper uses personal experience to work in military units of the Navy, and data from the literature. Terms of sailing ships off the summer season are defined as difficult. The crew during a combat mission felt the risks associated with movements of the ship in difficult meteorological conditions, and associated with the implementation of the task. The development of ship's technical equipment, working in isolated groups, functioning within a limited space, noise, vibration, electromagnetic waves heighten the emotional burden on crew members. Military service on Navy ships require high psycho-physical predisposition, resistance to stress. The crucial factor is proper selection among the candidates based on psychiatric and psychological counseling for military and medical jurisprudence. Also plays a significant role for training doctors and specialists in psychoprophylaxy of military units in the field of mental hygiene.

Randomized controlled trials (RCTs) are considered the gold standard in research design for establishing treatment efficacy. However, the rigorous and highly controlled conditions of RCTs can be difficult to attain when conducting research among individuals living with a confluence of disability, low socioeconomic status, and being a member of a racial/ethnic minority group, who may be more likely to have unstable life circumstances. Research on effective interventions for these groups is urgently needed, as evidence regarding approaches to reduce health disparities and improve health outcomes is lacking. In this methodological paper we discuss the challenges and lessons learned in implementing the Lifestyle Redesign® for Pressure Ulcer Prevention in Spinal Cord Injury (LR-PUPS) study among a highly disadvantaged population. These issues are discussed in terms of strategies to enhance recruitment, retention, and intervention relevance to the target population. Recommendations for researchers seeking to conduct RCTs among socioeconomically disadvantaged, ethnically diverse populations are provided. PMID:23262157

Direct functionalization processes: a journey from palladium to copper to iron to nickel to metal-free coupling reactions.

PubMed

Mousseau, James J; Charette, André B

2013-02-19

The possibility of finding novel disconnections for the efficient synthesis of organic molecules has driven the interest in developing technologies to directly functionalize C-H bonds. The ubiquity of these bonds makes such transformations attractive, while also posing several challenges. The first, and perhaps most important, is the selective functionalization of one C-H bond over another. Another key problem is inducing reactivity at sites that have been historically unreactive and difficult to access without prior inefficient prefunctionalization. Although remarkable advances have been made over the past decade toward solving these and other problems, several difficult tasks remain as researchers attempt to bring C-H functionalization reactions into common use. The functionalization of sp(3) centers continues to be challenging relative to their sp and sp(2) counterparts. Directing groups are often needed to increase the effective concentration of the catalyst at the targeted reaction site, forming thermodynamically stable coordination complexes. As such, the development of removable or convertible directing groups is desirable. Finally, the replacement of expensive rare earth reagents with less expensive and more sustainable catalysts or abandoning the use of catalysts entirely is essential for future practicality. This Account describes our efforts toward solving some of these quandaries. We began our work in this area with the direct arylation of N-iminopyridinium ylides as a universal means to derivatize the germane six-membered heterocycle. We found that the Lewis basic benzoyl group of the pyridinium ylide could direct a palladium catalyst toward insertion at the 2-position of the pyridinium ring, forming a thermodynamically stable six-membered metallocycle. Subsequently we discovered the arylation of the benzylic site of 2-picolonium ylides. The same N-benzoyl group could direct a number of inexpensive copper salts to the 2-position of the pyridinium ylide, which led to the first description of a direct copper-catalyzed alkenylation onto an electron-deficient arene. This particular directing group offers two advantages: (1) it can be easily appended and removed to reveal the desired pyridine target, and (2) it can be incorporated in a cascade process in the preparation of pharmacologically relevant 2-pyrazolo[1,5-a]pyridines. This work has solved some of the challenges in the direct arylation of nonheterocyclic arenes, including reversing the reactivity often observed with such transformations. Readily convertible directing groups were applied to facilitate the transformation. We also demonstrated that iron can promote intermolecular arylations effectively and that the omission of any metal still permits intramolecular arylation reactions. Lastly, we recently discovered a nickel-catalyzed intramolecular arylation of sp(3) C-H bonds. Our mechanistic investigations of these processes have elucidated radical pathways, opening new avenues in future direct C-H functionalization reactions.

An efficient group multicast routing for multimedia communication

NASA Astrophysics Data System (ADS)

Wang, Yanlin; Sun, Yugen; Yan, Xinfang

2004-04-01

Group multicasting is a kind of communication mechanism whereby each member of a group sends messages to all the other members of the same group. Group multicast routing algorithms capable of satisfying quality of service (QoS) requirements of multimedia applications are essential for high-speed networks. We present a heuristic algorithm for group multicast routing with end to end delay constraint. Source-specific routing trees for each member are generated in our algorithm, which satisfy member"s bandwidth and end to end delay requirements. Simulations over random network were carried out to compare proposed algorithm performance with Low and Song"s. The experimental results show that our proposed algorithm performs better in terms of network cost and ability in constructing feasible multicast trees for group members. Moreover, our algorithm achieves good performance in balancing traffic, which can avoid link blocking and enhance the network behavior efficiently.

Work with dreams in the group analysis represents an important part of the analytical work, with insight into unconscious experiences of the individual dreamer, and his transferrential relations with the therapist, other members of the group, and with the group as a whole. The way dreams are addressed varies from one therapist to another, and in line with that, members of the group have varying frequency of dreams. In groups of psychotic patients dreams are generally rarely discussed and interpreted by the group, with analysis mainly resting on the manifested content. This paper describes a long-term group of psychotic patients which, after sharing the dreams of several members and daydreams of one female patient, their interpretation and reception in the group achieved better cohesion and improved communication and interaction, i.e. created a group matrix. Furthermore, through the content of dreams in the group, traumatic war experiences of several of the group members were opened and discussed, which brought with it recollections of the traumatic life situations of other group members. In expressing a daydream, a female member of the group revealed the background for her behaviour which was earlier interpreted as a negative symptom of the illness.

Hypertension prevalence in the African American community is greater than in all other ethnic groups. Cultural perceptions of health and disease introduce barriers to providing effective care. The purpose of this study was to identify racial differences in the perceived causes of hypertension, current behaviors performed to control blood pressure, and perceived barriers to preventing or treating hypertension. A self-administered survey of patients seen for medical care in a primary care network was conducted. The survey was developed to measure perceptions of hypertension etiology and treatments. Data from African American (n = 69) and Caucasian (n = 218) respondents were used to assess racial differences in perceptions of blood pressure control. About half of respondents knew their current blood pressures. African American patients were significantly less likely to believe that hypertension was caused by a lack of exercise and obesity. Significantly more Caucasians were less likely to report cutting down on table salt and taking prescription medications for blood pressure control. Both African Americans and Caucasians believed that sodium reduction was the most easily changed behavior to control their blood pressure, while both groups identified weight loss as being the most difficult. Racial differences exist in the perceived causes and treatments of high blood pressure, indicating a need for further patient education. When treating and counseling patients, physicians and support staff members must be sensitive to racial diversity and strive to offer culturally relevant solutions, especially for behaviors perceived as most difficult to change.

To examine associations among diet quality and dairy group membership, membership duration and non-member status for women and school-aged children in rural Kenya. A cross-sectional survey, using chain referral sampling, was conducted and diet quality indices and prevalence of inadequate intake (PII) were estimated using the 'estimated average requirement' cut-off point method from single 24 h recalls, using a Kenyan nutrient database. PII was compared among members and non-members and among membership-duration groups. Women and children of dairy group members (n 88), across membership-duration groups (1-3, 4-6, 7-9 and 10+ years), and non-members (n 23) living among members. Small farms in central Kenya. Members had higher energy, percentage of energy from animal-source foods and dietary diversity. Member women and children had lower PII for respectively seven and three of eleven micronutrients. Reduced PII for milk-source micronutrients was associated with membership duration for women. Many member women (38%) had inadequate vitamin A intake and 39% of member children had inadequate Zn intake. Members' PII was also high (>45%) for Fe, Ca and vitamin B12. A higher prevalence of being overweight among member women compared with non-member women suggested nutrition transition effects of higher farm productivity. Dairy group membership was positively associated with adequate quantity and quality of diets for women and children. Long-term membership was insufficient to address micronutrient deficiencies. Understanding and addressing barriers to better diet quality and strategies to mitigate negative nutrition transition effects are needed to optimize nutritional outcomes of dairy group membership.

Social facilitation of eating novel food in tufted capuchin monkeys (Cebus apella): input provided by group members and responses affected in the observer.

PubMed

Addessi, E; Visalberghi, E

2001-11-01

Learning about food palatability from watching what conspecifics eat might be one of the advantages of group living. A previous study investigated whether group members' presence or eating activity account for social facilitation of eating of foods never previously tasted. Capuchins encountered novel colored foods when (1) alone (Alone condition) or (2) with group members visible in the nearby cage (Group-present condition) or (3) with group members present and eating a familiar food that had not been colored (Group+food condition). Social facilitation of eating occurred when group members were eating, despite the difference in color between the familiar food eaten by them and the novel food presented to the experimental subject. To clarify what subjects learnt from group members when social facilitation occurred, we further analyze here the data from the previous study. The number of visual exposures to the colored novel food (as a group member) correlated with increased consumption of that novel food when encountered later (as experimental subject). In contrast, the number of times that an individual fed on the familiar food (as a group member) did not decrease its consumption of novel food (as experimental subject). Therefore, capuchins (1) habituated to the colors of the novel foods, and (2) did not take into account that seeing group members eating a food does not provide information about the palatability of a differently colored food. Since social facilitation of eating occurs when foods do not match in color, at least in capuchins, social facilitation of eating should not be considered as a way of learning about a safe diet, but rather as a way of overcoming neophobia.

Oxytocin motivates non-cooperation in intergroup conflict to protect vulnerable in-group members.

2012-01-01

Intergroup conflict is often driven by an individual's motivation to protect oneself and fellow group members against the threat of out-group aggression, including the tendency to pre-empt out-group threat through a competitive approach. Here we link such defense-motivated competition to oxytocin, a hypothalamic neuropeptide involved in reproduction and social bonding. An intergroup conflict game was developed to disentangle whether oxytocin motivates competitive approach to protect (i) immediate self-interest, (ii) vulnerable in-group members, or (iii) both. Males self-administered oxytocin or placebo (double-blind placebo-controlled) and made decisions with financial consequences to themselves, their fellow in-group members, and a competing out-group. Game payoffs were manipulated between-subjects so that non-cooperation by the out-group had high vs. low impact on personal payoff (personal vulnerability), and high vs. low impact on payoff to fellow in-group members (in-group vulnerability). When personal vulnerability was high, non-cooperation was unaffected by treatment and in-group vulnerability. When personal vulnerability was low, however, in-group vulnerability motivated non-cooperation but only when males received oxytocin. Oxytocin fuels a defense-motivated competitive approach to protect vulnerable group members, even when personal fate is not at stake.

2005-01-01

Background: Support groups for families of persons with mental illness are emerging as significant components in psychosocial rehabilitation programmes. Aim: To ascertain the expectations of family members who attend family support group meetings and to find out the efficacy of such programmes. Methods: The data were collected from support group members using a semi-structured interview schedule. The study sample (n=20) was drawn from family members who attended the support group meetings regularly for a minimum period of 6 months. Data analysis was done using percentile. Results: Analysis of the data revealed that members attending the support group meetings expected to get more information about the illness, develop skills to cope with problems at home and learn skills to deal with the ill person. An important finding of the study was that the members developed a ‘feeling of togetherness’ as a result of being a member of a group with common aims. Conclusion: Participation in a support group meeting positively affects key variables in the participant's adaptation to mental illness in a relative. PMID:20814460

Genetic Testing in Psychiatry: A Review of Attitudes and Beliefs

PubMed Central

Lawrence, Ryan E; Appelbaum, Paul S.

2012-01-01

The advent of genetic testing for psychiatric conditions raises difficult questions about when and how the tests should be used. Development of policies regarding these issues may be informed in a variety of ways by the views of key stakeholders: patients, family members, healthcare professionals, and the general public. Here we review empirical studies of attitudes towards genetic testing among these groups. Patients and family members show strong interest in diagnostic and predictive genetic testing, and to a considerable extent psychiatrists share their enthusiasm. Prenatal test utilization seems likely to depend both on parental views on abortion and the seriousness of the disorder. Parents show a surprising degree of interest in predictive testing of children, even when there are no preventive interventions available. Many persons report themselves ready to alter their lifestyles and plans for marriage and family in response to test results. Respondents also fear negative consequences, from discrimination to being unable to cope with knowledge of their “genetic fate.” Empirical studies of beliefs about genetic testing suggest tests are likely to be embraced widely, but the studies have methodologic limitations, reducing the certainty of their conclusions, and indicating a need for further research with more representative samples.

2012-01-01

Purpose: The main objective of this survey is to describe the current practice of thoracic anesthesia in the Middle Eastern (ME) region. Methods: A prospective online survey. An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East. Questions concerned ventilation strategies during one-lung ventilation (OLV), anesthesia regimen, mode of postoperative analgesia, use of lung isolation techniques, and use of i.v. fluids. Results: Volume-controlled ventilation was favored over pressure-controlled ventilation (62% vs 38% of respondents, P<0.05); 43% report the routine use of positive end-expiratory pressure. One hundred percent of respondents report using double-lumen tube (DLT) as a first choice airway to establish OLV. Nearly a third of respondents, 31.1%, report never using bronchial blocker (BB) in their thoracic anesthesia practice. Failure to pass a DLT and difficult airway are the most commonly cited indications for BB use. Regarding postoperative analgesia, the majority 61.8% favor thoracic epidural analgesia over other techniques (P<0.05). Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice. PMID:23162388

Transactional sex and HIV: understanding the gendered structural drivers of HIV in fishing communities in Southern Malawi

Background In Southern Malawi, the fishing industry is highly gendered, with men carrying out the fishing and women processing, drying and selling the fish. Research has shown that individuals living in fishing communities in low-income countries are particularly vulnerable to HIV infection. One of the key drivers of HIV in fishing communities is transactional sex. In the fishing industry this takes the form of “fish-for-sex” networks where female fish traders exchange sex with fishermen for access to or more favourable prices of fish. By controlling the means of production, the power dynamics in these exchanges favour men and can make it more difficult for women to negotiate safe sex. Methods Qualitative methods were used to collect data on gendered drivers of transactional sex in the fishing community and how different groups perceive HIV risk in these transactions. Observation, focus group discussions and semi-structured interviews were undertaken with members of the fishing communities, including men and women directly and indirectly involved in fishing. Results In fishing communities transactional sex was prevalent across a spectrum ranging from gift giving within relationships, to sex for fish exchanges, to sex worker encounters. Power differences between couples in transactional sexual encounters shape individual’s abilities to negotiate condom use (with women being at a particularly disadvantaged negotiating position). The context and motivations for transactional sex varied and was mediated by economic need and social position both of men and women. Female fish traders new to the industry and boat crew members who travelled for work and experienced difficult living conditions often engaged in transactional sex. Conclusions Transactional sex is common in Malawian fishing communities, with women particularly vulnerable in negotiations because of existing gendered power structures. Although knowledge and understanding of the HIV risk associated with transactional sex was common, this did not appear to result in the adoption of risk reduction strategies. This suggests that specially targeted strategies to increase women’s economic empowerment and tackle the structural drivers of women’s HIV risk could be important in fishing communities.

We compared available guidelines on the management of mental disorders and stress-related psychological symptoms in an occupational healthcare setting and determined their development and reporting quality. To identify eligible guidelines, we systematically searched National Guideline Clearinghouse, Guidelines International Network Library and PubMed. Members of the International Commission on Occupational Health (ICOH), were also consulted. Guidelines recommendations were compared and reporting quality was assessed using the AGREE II instrument. Of 2126 titles retrieved, 14 guidelines were included: 1 Japanese, 2 Finnish, 2 Korean, 2 British and 7 Dutch. Four guidelines were of high-reporting quality. Best described was the Scope and Purpose, and the poorest described were competing interests (Editorial independence) and barriers and facilitators for implementation (Applicability). Key recommendations were often difficult to identify. Most guidelines recommend employing an inventory of symptoms, diagnostic classification, performance problems and workplace factors. All guidelines recommend specific return-to-work interventions, and most agreed on psychological treatment and communication between involved stakeholders. Practice guidelines to address work disability due to mental disorders and stress-related symptoms are available in various countries around the world, however, these guidelines are difficult to find. To promote sharing, national guidelines should be accessible via established international databases. The quality of the guideline's developmental process varied considerably. To increase quality and applicability, guideline developers should adopt a common structure for the development and reporting of their guidelines, for example Appraisal of Guidelines for Research and Evaluation (AGREE) criteria. Owing to differences in social systems, developers can learn from each other through reviews of this kind. Published by the BMJ Publishing Group Limited.

Tensile and compressive modulus of elasticity of pultruded fiber-reinforced polymer composite materials

Many researches focused on the mechanical properties of steel and concrete have been carried out for applications in the construction industry. However, in order to clarify the mechanical properties of pultruded fiber-reinforced polymer (PFRP) structural members for construction, testing is needed. Deriving the mechanical properties of PFRP structural members through testing is difficult, however, because some members cannot be tested easily due to their cross-section dimensions. This paper reports a part of studies that attempt to present conservative results in the case of members that cannot be tested reasonably. The authors obtained and compared experimental and theoretical modulus of elasticity values. If the mechanical properties of PFRP members can be predicted using reasonable and conservative values, then the structure can be designed economically and safely even in the early design stages. To this end, this paper proposes a strain energy approach as a conservative and convenient way to predict the mechanical properties of PFRP structural members. The strain energy data obtained can be used to predict the mechanical properties of PFRP members in the construction field.

Science, in our case the climate and geosciences, is increasingly interdisciplinary. Scientists must therefore communicate across disciplinary boundaries. For this communication to be successful, scientists must write clearly and concisely, yet the historically poor standard of scientific writing does not seem to be improving. Scientific writing must improve, and the key to long-term improvement lies with the early-career scientist (ECS). Many interventions exist for an ECS to improve their writing, like style guides and courses. However, momentum is often difficult to maintain after these interventions are completed. Continuity is key to improving writing. This paper introduces the ClimateSnack project, which aims to motivate ECSs to develop and continue to improve their writing and communication skills. The project adopts a peer-learning framework where ECSs voluntarily form writing groups at different institutes around the world. The group members learn, discuss, and improve their writing skills together. Several ClimateSnack writing groups have formed. This paper examines why some of the groups have flourished and others have dissolved. We identify the challenges involved in making a writing group successful and effective, notably the leadership of self-organized groups, and both individual and institutional time management. Within some of the groups, peer learning clearly offers a powerful tool to improve writing as well as bringing other benefits, including improved general communication skills and increased confidence.

Difficult incidents and tutor interventions in problem-based learning tutorials.

Tutors report difficult incidents and distressing conflicts that adversely affect learning in their problem-based learning (PBL) groups. Faculty development (training) and peer support should help them to manage this. Yet our understanding of these problems and how to deal with them often seems inadequate to help tutors. The aim of this study was to categorise difficult incidents and the interventions that skilled tutors used in response, and to determine the effectiveness of those responses. Thirty experienced and highly rated tutors in our Year 1 and 2 medical curriculum took part in semi-structured interviews to: identify and describe difficult incidents; describe how they responded, and assess the success of each response. Recorded and transcribed data were analysed thematically to develop typologies of difficult incidents and interventions and compare reported success or failure. The 94 reported difficult incidents belonged to the broad categories 'individual student' or 'group dynamics'. Tutors described 142 interventions in response to these difficult incidents, categorised as: (i) tutor intervenes during tutorial; (ii) tutor gives feedback outside tutorial, or (iii) student or group intervenes. Incidents in the 'individual student' category were addressed relatively unsuccessfully (effective < 50% of the time) by response (i), but with moderate success by response (ii) and successfully (> 75% of the time) by response (iii). None of the interventions worked well when used in response to problems related to 'group dynamics'. Overall, 59% of the difficult incidents were dealt with successfully. Dysfunctional PBL groups can be highly challenging, even for experienced and skilled tutors. Within-tutorial feedback, the treatment that tutors are most frequently advised to apply, was often not effective. Our study suggests that the collective responsibility of the group, rather than of the tutor, to deal with these difficulties should be emphasised.

Liddle, Jacki; Gustafsson, Louise; Mitchell, Geoffrey; Pachana, Nancy A

2017-02-01

Recognizing the clinical importance and safety and well-being implications for the population, a multidisciplinary team has been researching older drivers and driving cessation issues for more than 15 years. Using empirical approaches, the team has explored quality of life and participation outcomes related to driving and nondriving for older people and has developed interventions to improve outcomes after driving cessation. The team members represent occupational therapists, medical practitioners, and clinical and neuropsychologists. While building the evidence base for driving- and driving cessation-related clinical practice, the researchers have also had first-hand experiences of interruptions to their own or parents' driving; involvement of older family members in road crashes; and provision of support during family members' driving assessment and cessation. This has led to reflection on their understandings and re-evaluation and refocusing of their perspectives in driving cessation research. This work will share the narratives of the authors and note their developing perspectives and foci within research as well as their clinical practice. Personal reflections have indicated the far-reaching implications for older drivers and family members of involvement in road crashes: the potential for interruptions to driving as a time for support and future planning and the conflicting and difficult roles of family members within the driving cessation process. Overall the lived, personal experience of the authors has reinforced the complex nature of driving and changes to driving status for the driver and their support team and the need for further research and support. © The Author 2016.

2000-01-01

OBJECTIVES: To survey operating theatre and intensive care unit staff about attitudes concerning error, stress, and teamwork and to compare these attitudes with those of airline cockpit crew. DESIGN:: Cross sectional surveys. SETTING:: Urban teaching and non-teaching hospitals in the United States, Israel, Germany, Switzerland, and Italy. Major airlines around the world. PARTICIPANTS:: 1033 doctors, nurses, fellows, and residents working in operating theatres and intensive care units and over 30 000 cockpit crew members (captains, first officers, and second officers). MAIN OUTCOME MEASURES:: Perceptions of error, stress, and teamwork. RESULTS:: Pilots were least likely to deny the effects of fatigue on performance (26% v 70% of consultant surgeons and 47% of consultant anaesthetists). Most pilots (97%) and intensive care staff (94%) rejected steep hierarchies (in which senior team members are not open to input from junior members), but only 55% of consultant surgeons rejected such hierarchies. High levels of teamwork with consultant surgeons were reported by 73% of surgical residents, 64% of consultant surgeons, 39% of anaesthesia consultants, 28% of surgical nurses, 25% of anaesthetic nurses, and 10% of anaesthetic residents. Only a third of staff reported that errors are handled appropriately at their hospital. A third of intensive care staff did not acknowledge that they make errors. Over half of intensive care staff reported that they find it difficult to discuss mistakes. CONCLUSIONS: Medical staff reported that error is important but difficult to discuss and not handled well in their hospital. Barriers to discussing error are more important since medical staff seem to deny the effect of stress and fatigue on performance. Further problems include differing perceptions of teamwork among team members and reluctance of senior theatre staff to accept input from junior members.

2015-04-01

We tested whether the perceived physical attractiveness of a group is greater than the average attractiveness of its members. In nine studies, we find evidence for the so-called group attractiveness effect (GA-effect), using female, male, and mixed-gender groups, indicating that group impressions of physical attractiveness are more positive than the average ratings of the group members. A meta-analysis on 33 comparisons reveals that the effect is medium to large (Cohen's d = 0.60) and moderated by group size. We explored two explanations for the GA-effect: (a) selective attention to attractive group members, and (b) the Gestalt principle of similarity. The results of our studies are in favor of the selective attention account: People selectively attend to the most attractive members of a group and their attractiveness has a greater influence on the evaluation of the group. © 2015 by the Society for Personality and Social Psychology, Inc.

Direct fitness benefits and kinship of social foraging groups in an Old World tropical babbler

2018-01-01

Molecular studies have revealed that social groups composed mainly of nonrelatives may be widespread in group-living vertebrates, but the benefits favoring such sociality are not well understood. In the Old World, birds often form conspecific foraging groups that are maintained year-round and offspring usually disperse to other social groups. We tested the hypothesis that nonbreeding group members are largely unrelated and gain direct fitness benefits through breeding opportunities (males) and brood parasitism (females) in the tropical gray-throated babbler, Stachyris nigriceps, in Malaysian Borneo. Babblers foraged in social groups containing one or more breeding pairs (median = 8 group members of equal sex ratio), but group members rarely assisted with breeding (9% of 67 breeding pairs had a third helper; exhibiting facultative cooperative breeding). Although 20% of 266 group member dyads were first-order relatives of one or both members of the breeding pairs, 80% were unrelated. Male group members gained direct fitness benefits through extrapair and extra-group paternity (25% of 73 offspring), which was independent of their relatedness to the breeding pair and increased with decreasing group size. In contrast, females did not gain direct fitness benefits through brood parasitism. The low levels of relatedness and helping in social groups suggest that most group members do not gain indirect fitness benefits by helping to raise unrelated offspring. These findings highlight the importance of examining benefits of sociality for unrelated individuals that largely do not help and broaden the direct fitness benefits of group foraging beyond assumed survival benefits.

Gene Loss and Horizontal Gene Transfer Contributed to the Genome Evolution of the Extreme Acidophile “Ferrovum”

2016-01-01

Acid mine drainage (AMD), associated with active and abandoned mining sites, is a habitat for acidophilic microorganisms that gain energy from the oxidation of reduced sulfur compounds and ferrous iron and that thrive at pH below 4. Members of the recently proposed genus “Ferrovum” are the first acidophilic iron oxidizers to be described within the Betaproteobacteria. Although they have been detected as typical community members in AMD habitats worldwide, knowledge of their phylogenetic and metabolic diversity is scarce. Genomics approaches appear to be most promising in addressing this lacuna since isolation and cultivation of “Ferrovum” has proven to be extremely difficult and has so far only been successful for the designated type strain “Ferrovum myxofaciens” P3G. In this study, the genomes of two novel strains of “Ferrovum” (PN-J185 and Z-31) derived from water samples of a mine water treatment plant were sequenced. These genomes were compared with those of “Ferrovum” sp. JA12 that also originated from the mine water treatment plant, and of the type strain (P3G). Phylogenomic scrutiny suggests that the four strains represent three “Ferrovum” species that cluster in two groups (1 and 2). Comprehensive analysis of their predicted metabolic pathways revealed that these groups harbor characteristic metabolic profiles, notably with respect to motility, chemotaxis, nitrogen metabolism, biofilm formation and their potential strategies to cope with the acidic environment. For example, while the “F. myxofaciens” strains (group 1) appear to be motile and diazotrophic, the non-motile group 2 strains have the predicted potential to use a greater variety of fixed nitrogen sources. Furthermore, analysis of their genome synteny provides first insights into their genome evolution, suggesting that horizontal gene transfer and genome reduction in the group 2 strains by loss of genes encoding complete metabolic pathways or physiological features contributed to the observed diversification.

Biospecimens must have appropriate clinical annotation (data) to ensure optimal quality for both patient care and research. Clinical preanalytic variables are the focus of this study. To define the essential preanalytic variables (data fields) that should be attached to every collected biospecimen and to provide a complete list of such variables, along with their relative importance, which can vary, depending on downstream use, institutional needs, and information technology capabilities. The College of American Pathologists Diagnostic Intelligence and Health Information Technology Committee sponsored a Biorepository Working Group to develop a ranked list of the preanalytic variables for annotating biospecimens. Members of the working group were experts in anatomic, clinical, and molecular pathology; biobanking; medical informatics; and accreditation. Several members had experience with federal government programs, such as the National Cancer Institute's Biospecimens and Biorepository Branch and the National Cancer Institute's Community Cancer Center Program. Potential preanalytic variables were identified and ranked along with available supporting evidence, definitions, and potential negative effects if the variable was not attached to the biospecimen. Additional national and international stakeholders reviewed the draft manuscript. The ranked listing of 170 preanalytic variables produced can be used as a guide for site-specific implementation into patient care and/or research biorepository processes. Conclusions.-In our collective experience, it is often difficult to choose which of the many preanalytic variables to attach to any specific set of biospecimens used for patient care and/or research. The provided ranked list should aid in the selection of preanalytic variables for a given biospecimen collection.

Approximating Optimal Behavioural Strategies Down to Rules-of-Thumb: Energy Reserve Changes in Pairs of Social Foragers

PubMed Central

Rands, Sean A.

2011-01-01

Functional explanations of behaviour often propose optimal strategies for organisms to follow. These ‘best’ strategies could be difficult to perform given biological constraints such as neural architecture and physiological constraints. Instead, simple heuristics or ‘rules-of-thumb’ that approximate these optimal strategies may instead be performed. From a modelling perspective, rules-of-thumb are also useful tools for considering how group behaviour is shaped by the behaviours of individuals. Using simple rules-of-thumb reduces the complexity of these models, but care needs to be taken to use rules that are biologically relevant.

Approximating optimal behavioural strategies down to rules-of-thumb: energy reserve changes in pairs of social foragers.

PubMed

Rands, Sean A

Functional explanations of behaviour often propose optimal strategies for organisms to follow. These 'best' strategies could be difficult to perform given biological constraints such as neural architecture and physiological constraints. Instead, simple heuristics or 'rules-of-thumb' that approximate these optimal strategies may instead be performed. From a modelling perspective, rules-of-thumb are also useful tools for considering how group behaviour is shaped by the behaviours of individuals. Using simple rules-of-thumb reduces the complexity of these models, but care needs to be taken to use rules that are biologically relevant. Here, we investigate the similarity between the outputs of a two-player dynamic foraging game (which generated optimal but complex solutions) and a computational simulation of the behaviours of the two members of a foraging pair, who instead followed a rule-of-thumb approximation of the game's output. The original game generated complex results, and we demonstrate here that the simulations following the much-simplified rules-of-thumb also generate complex results, suggesting that the rule-of-thumb was sufficient to make some of the model outcomes unpredictable. There was some agreement between both modelling techniques, but some differences arose - particularly when pair members were not identical in how they gained and lost energy. We argue that exploring how rules-of-thumb perform in comparison to their optimal counterparts is an important exercise for biologically validating the output of agent-based models of group behaviour.

Council of International Neonatal Nurses (COINN) Global Neonatal Provider Database Initiative (CGNPD): Results From an Implementation Focus Group.

The neonatal nurses are the key component of the essential workforce necessary to address the healthcare needs of the infants globally. The paucity of the data regarding the availability and training of the neonatal workforce challenges the stakeholders at the regional, national, and global levels. The lack of these data makes strategic planning for initiatives especially in low-resourced countries difficult. Up-to-date data are critically needed to describe the role neonatal nurses play in global newborn health outcomes. The purpose of the COINN Global Neonatal Provider Database Initiative (CGNPD) was to develop a workforce database by developing survey questions, conducting a focus group to determine the key reasons such a database was needed and how best to implement it, and incorporating these comments into the workforce survey and launch. Pilot testing of the draft survey instrument was done. This article reports on the findings from the focus group and the development of the survey. A qualitative design using the focus group method was used. The focus group discussions were guided by semi-structured interview questions that had been developed prior to the focus group by neonatal experts. A convenience sample of 14 members from the international delegates and project advisory members who attended the COINN 2013 in Belfast, Northern Ireland, participated. These participants represented 10 countries. Thematic analysis was conducted using verbatim transcripts of the focus group data. Four main themes emerged: (1) the invisibility of neonatal nurses, (2) benchmarking needs for quality and standards, (3) need for partnership to implement the database, and (4) setting priorities for variables needed for the most salient database. The questionnaire examined participants' perceptions of the significance of and the future utilization of the workforce database and elements that should be included in the survey. The global neonatal workforce database is needed to describe who the neonatal nurses are in each country, what they do, how they are trained, and where they work. The data from the focus group aided in the development of the workforce survey that has been pilot tested and provides critical information to guide COINN's global implementation of the database project.

Oxytocin Motivates Non-Cooperation in Intergroup Conflict to Protect Vulnerable In-Group Members

Intergroup conflict is often driven by an individual's motivation to protect oneself and fellow group members against the threat of out-group aggression, including the tendency to pre-empt out-group threat through a competitive approach. Here we link such defense-motivated competition to oxytocin, a hypothalamic neuropeptide involved in reproduction and social bonding. An intergroup conflict game was developed to disentangle whether oxytocin motivates competitive approach to protect (i) immediate self-interest, (ii) vulnerable in-group members, or (iii) both. Males self-administered oxytocin or placebo (double-blind placebo-controlled) and made decisions with financial consequences to themselves, their fellow in-group members, and a competing out-group. Game payoffs were manipulated between-subjects so that non-cooperation by the out-group had high vs. low impact on personal payoff (personal vulnerability), and high vs. low impact on payoff to fellow in-group members (in-group vulnerability). When personal vulnerability was high, non-cooperation was unaffected by treatment and in-group vulnerability. When personal vulnerability was low, however, in-group vulnerability motivated non-cooperation but only when males received oxytocin. Oxytocin fuels a defense-motivated competitive approach to protect vulnerable group members, even when personal fate is not at stake. PMID:23144787

Adrift in the Gray Zone: IRB Perspectives on Research in the Learning Health System.

Human subjects protection in healthcare contexts rests on the premise that a principled boundary distinguishes clinical research and clinical practice. However, growing use of evidence-based clinical practices by health systems makes it increasingly difficult to disentangle research from a wide range of clinical activities that are sometimes called "research on medical practice" (ROMP), including quality improvement activities and comparative effectiveness research. The recent growth of ROMP activities has created an ethical and regulatory gray zone with significant implications for the oversight of human subjects research. We conducted six semi-structured, open-ended focus group discussions with IRB members to understand their experiences and perspectives on ethical oversight of ROMP, including randomization of patients to standard treatments. Our study revealed that IRB members are unclear or divided on the central questions at stake in the current policy debate over ethical oversight of ROMP: IRB members struggle to make a clear distinction between clinical research and medical practice improvement, lack consensus on when ROMP requires IRB review and oversight, and are uncertain about what constitutes incremental risk when patients are randomized to different treatments, any of which may be offered in usual care. They characterized the central challenge as a balancing act, between, on the one hand, making information fully transparent to patients and providing adequate oversight, and on the other hand, avoiding a chilling effect on the research process or harming the physician-patient relationship. Evidence-based guidance that supports IRB members in providing adequate and effective oversight of ROMP without impeding the research process or harming the physician-patient relationship is necessary to realize the full benefits of the learning health system.

Reticulate evolution in North American black-fruited hawthorns (Crataegus section Douglasia; Rosaceae): evidence from nuclear ITS2 and plastid sequences

PubMed Central

Zarrei, M.; Stefanović, S.; Dickinson, T. A.

2014-01-01

Background and Aims The taxonomic complexity of Crataegus (hawthorn; Rosaceae, Maleae), especially in North America, has been attributed by some to hybridization in combination with gametophytic apomixis and polyploidization, whereas others have considered the roles of hybridization and apomixis to be minimal. Study of the chemical composition and therapeutic value of hawthorn extracts requires reproducible differentiation of entities that may be difficult to distinguish by morphology alone. This study sought to address this by using the nuclear ribosomal spacer region ITS2 as a supplementary DNA barcode; however, a lack of success prompted an investigation to discover why this locus gave unsatisfactory results. Methods ITS2 was extensively cloned so as to document inter- and intraindividual variation in this locus, using hawthorns of western North America where the genus Crataegus is represented by only two widely divergent groups, the red-fruited section Coccineae and the black-fruited section Douglasia. Additional sequence data from selected loci on the plastid genome were obtained to enhance further the interpretation of the ITS2 results. Key Results In the ITS2 gene tree, ribotypes from western North American hawthorns are found in two clades. Ribotypes from diploid members of section Douglasia occur in one clade (with representatives of the east-Asian section Sanguineae). The other clade comprises those from diploid and polyploid members of section Coccineae. Both clades contribute ribotypes to polyploid Douglasia. Data from four plastid-derived intergenic spacers demonstrate the maternal parentage of these allopolyploids. Conclusions Repeated hybridization between species of section Douglasia and western North American members of section Coccineae involving the fertilization of unreduced female gametes explains the observed distribution of ribotypes and accounts for the phenetic intermediacy of many members of section Douglasia.

Common issues for parents in a methadone maintenance group.

Change has been noted in some of the group members. For example, one long-term group member who never spoke when she was in a previous group that focused on addiction-related problems has become the role model for other members. In this group, she says, she feels more competent. She is appropriately outspoken and has established relationships with her children which consistently underpin the parent-child boundaries that need to be drawn. One specific issue she resolved involved her 19-year-old son and his girlfriend who was pregnant with the group member's grandchild. By role playing the different positions that each of these people held in the home (the group member was paying the rent and had the right to set the rules, the girlfriend was feeling unaccepted by the group member and was acting out inappropriately, and the son was caught between trying to please the two females), the group member was able to clarify for herself how to approach future conflicts. A second member has improved her relationship with her youngest son (age 3) but still struggles with her 15-year-old daughter. What has been most effective for her was teaching her to count to 10 before responding to what she considers the goading of both of her children. In addition, she was feeling pressured by her mother, in whose house she lives, to have her son toilet trained.(ABSTRACT TRUNCATED AT 250 WORDS)

The Insensitive Ruins It All: Compositional and Compilational Influences of Social Sensitivity on Collective Intelligence in Groups.

PubMed

Meslec, Nicoleta; Aggarwal, Ishani; Curseu, Petru L

2016-01-01

A group's collective intelligence reflects its capacity to perform well across a variety of cognitive tasks and it transcends the individual intelligence of its members. Previous research shows that group members' social sensitivity is a potential antecedent of collective intelligence, yet it is still unclear whether individual or group-level indices are responsible for the positive association between social sensitivity and collective intelligence. In a comprehensive manner, we test the extent to which both compositional (lowest and highest individual score) and compilational aspects (emergent group level) of social sensitivity are associated with collective intelligence. This study has implications for research that explores groups as information processors, and for group design as it indicates how a group should be composed with respect to social sensitivity if the group is to reach high levels of collective intelligence. Our empirical results indicate that collectively intelligent groups are those in which the least socially sensitive group member has a rather high score on social sensitivity. Differently stated, (socially sensitive) group members cannot compensate for the lack of social sensitivity of the other group members.

Salient Multiculturalism Enhances Minority Group Members' Feelings of Power.

PubMed

Vorauer, Jacquie D; Quesnel, Matthew S

2017-02-01

The present research examined how messages advocating different intergroup ideologies affect outcomes relevant to minority group members' ability to exert power in exchanges with dominant group members. We expected that salient multiculturalism would have positive implications for minority group members' feelings of power by virtue of highlighting essential contributions they make to society, and that no such empowering effect would be evident for them in connection with alternative ideologies such as color-blindness or for dominant group members. Results across four studies involving different participant populations, operationalizations of ideology, ethnic minority groups, and experimental settings were consistent with these hypotheses and further indicated that the effects of salient multiculturalism on feelings of power had downstream implications for expectations of control in an ostensibly upcoming intergroup interaction and general goal-directed cognition.

Roles of participation and feedback in group potency.

2009-08-01

The roles of group participation and group performance feedback were examined as antecedents of group potency, i.e., beliefs shared among a work group's members about the general effectiveness of the work group. Also examined were how group participation and the congruence of the feedback received from different sources about performance predicted convergence in members' beliefs about group effectiveness. The sample comprised 61 work groups of professionals involved in Master in Business Administration (MBA) programs (284 participants). Mean group size was 4.6 members (SD = .58). 65% of participants were male, and 51% were between 30 and 40 years of age. Data were gathered at two measurement times. Increases in group participation were positively related to increases in group potency and the convergence in beliefs about group effectiveness among group members over time. Results supported the premise that group performance feedback is an antecedent of changes in group potency over time.

Application of meandering centreline migration modelling and object-based approach of Long Nab member

2017-04-01

Characterizing the complexity and heterogeneity of the geometries and deposits in meandering river system is an important concern for the reservoir modelling of fluvial environments. Re-examination of the Long Nab member in the Scalby formation of the Ravenscar Group (Yorkshire, UK), integrating digital outcrop data and forward modelling approaches, will lead to a geologically realistic numerical model of the meandering river geometry. The methodology is based on extracting geostatistics from modern analogous, meandering rivers that exemplify both the confined and non-confined meandering point bars deposits and morphodynamics of Long Nab member. The parameters derived from the modern systems (i.e. channel width, amplitude, radius of curvature, sinuosity, wavelength, channel length and migration rate) are used as a statistical control for the forward simulation and resulting object oriented channel models. The statistical data derived from the modern analogues is multi-dimensional in nature, making analysis difficult. We apply data mining techniques such as parallel coordinates to investigate and identify the important relationships within the modern analogue data, which can then be used drive the development of, and as input to the forward model. This work will increase our understanding of meandering river morphodynamics, planform architecture and stratigraphic signature of various fluvial deposits and features. We will then use these forward modelling based channel objects to build reservoir models, and compare the behaviour of the forward modelled channels with traditional object modelling in hydrocarbon flow simulations.

When Guild Interests and Professional Obligations Collide.

PubMed

Minkoff, Howard; Ecker, Jeffrey

2017-08-01

Physicians who work in medical organizations are called on to fulfill two roles: guild members who work to advance physician interests (eg, lobbying for tort reform) and professional society members who work to advance patient interests (eg, developing clinical guidelines). Most often, physicians' self-interest and their interest in patient well-being align. When they do not, members of a guild or profession may justify the prioritization of self-interest with a form of motivated reasoning (a process wherein physicians weigh data differently depending on whether it supports their a priori beliefs). This allows physicians to frame self-interest as being in the best interests of their patients (eg, tort reform makes malpractice insurance affordable and allows physicians to continue to serve their patients). When interests conflict, physicians must be cognizant of the forces at play, that is, self-interest or in-group interest on the one hand and obligations to patients on the other. This entails recognition and negation of motivated reasoning. Often the most difficult calculus is evaluating proposed actions that would disadvantage physicians but advantage patients. In such cases, the health care provider must be aware not only of the temptation to oppose the action for financial reasons, but also the equally natural temptation to frame the proposal as a threat to patient well-being. Ultimately recognizing that a central tenet of professionalism is the primacy of patient welfare should help physicians both to maintain their fidelity to patient good and to uphold their reputation for altruism.

Research on Ultrasonic Flaw Detection of Steel Weld in Spatial Grid Structure

2017-06-01

The welding quality of spatial grid member is an important link in quality control of steel structure. The paper analyzed the reasons that the welding seam of small-bore pipe with thin wall grid structure is difficult to be detected by ultrasonic wave from the theoretical and practical aspects. A series of feasible detection methods was also proposed by improving probe and operation approaches in this paper, and the detection methods were verified by project cases. Over the years, the spatial grid structure is widely used the engineering by virtue of its several outstanding characteristics such as reasonable structure type, standard member, excellent space integrity and quick installation. The wide application of spatial grid structure brings higher requirements on nondestructive test of grid structure. The implementation of new Code for Construction Quality Acceptance of Steel Structure Work GB50205-2001 strengthens the site inspection of steel structure, especially the site inspection of ultrasonic flaw detection in steel weld. The detection for spatial grid member structured by small-bore and thin-walled pipes is difficult due to the irregular influence of sound pressure in near-field region of sound field, sound beam diffusion generated by small bore pipe and reduction of sensitivity. Therefore, it is quite significant to select correct detecting conditions. The spatial grid structure of welding ball and bolt ball is statically determinate structure with high-order axial force which is connected by member bars and joints. It is welded by shrouding or conehead of member bars and of member bar and bolt-node sphere. It is obvious that to ensure the quality of these welding positions is critical to the quality of overall grid structure. However, the complexity of weld structure and limitation of ultrasonic detection method cause many difficulties in detection. No satisfactory results will be obtained by the conventional detection technology, so some special approaches must be used.

Sleeping sites, sleeping trees, and sleep-related behaviors of black crested gibbons (Nomascus concolor jingdongensis) at Mt. Wuliang, Central Yunnan, China.

Data on sleep-related behaviors were collected for a group of central Yunnan black crested gibbons (Nomascus concolor jingdongensis) at Mt. Wuliang, Yunnan, China from March 2005 to April 2006. Members of the group usually formed four sleeping units (adult male and juvenile, adult female with one semi-dependent black infant, adult female with one dependent yellow infant, and subadult male) spread over different sleeping trees. Individuals or units preferred specific areas to sleep; all sleeping sites were situated in primary forest, mostly (77%) between 2,200 and 2,400 m in elevation. They tended to sleep in the tallest and thickest trees with large crowns on steep slopes and near important food patches. Factors influencing sleeping site selection were (1) tree characteristics, (2) accessibility, and (3) easy escape. Few sleeping trees were used repeatedly by the same or other members of the group. The gibbons entered the sleeping trees on average 128 min before sunset and left the sleeping trees on average 33 min after sunrise. The lag between the first and last individual entering the trees was on average 17.8 min. We suggest that sleep-related behaviors are primarily adaptations to minimize the risk of being detected by predators. Sleeping trees may be chosen to make approach and attack difficult for the predator, and to provide an easy escape route in the dark. In response to cold temperatures in a higher habitat, gibbons usually sit and huddle together during the night, and in the cold season they tend to sleep on ferns and/or orchids.

Older but wilier: In-group accountability and the development of subjective group dynamics.

Abrams, Dominic; Rutland, Adam; Cameron, Lindsey; Ferrell, Jennifer

2007-01-01

To test social and cognitive variables that may affect the development of subjective group dynamics, the authors had 224 children between the ages of 5 and 12 years evaluate an in-group and an out-group and normative and deviant in-group members under conditions of high or low accountability to in-group peers. In-group bias and relative favorability to normative versus deviant in-group members (differential evaluation) increased when children were accountable to peers and as a function of perceptions of peer group acceptance of these members (differential inclusion). These effects were significantly larger among older children. Multiple classification ability was unrelated to judgments of group members. This study shows that the development of subjective group dynamics involves an increase in sensitivity to the normative aspects of the intergroup context. Copyright 2006 APA, all rights reserved.

Improving effectiveness of group exercise counseling for breast cancer survivors is needed. The objective of this study was to describe clinical observations, with research and translation implications, derived during group exercise counseling for breast cancer survivors. While implementing group session components of an effective social cognitive theory-based exercise intervention, observations were made through verbal discussion with study staff, review of participant feedback, and prospective journaling by the group facilitator. The intervention has been implemented 11 times (ie, 63 survivors; 66 group sessions). Thematic consistency, application to intervention goals and design, and implications were reconciled between 2 investigators. Breast cancer diagnosis was a strong source of commonality among group participants. Participant age, time since diagnosis, and expectation for group sessions (eg, group support vs health education) hindered group commonality. Barriers unique to the breast cancer experience were infrequent, but people-pleasing behavior was often identified as a barrier to adherence. Feeling at risk for cancer recurrence was a major concern. Some participants required referral for mental health evaluation for preexisting conditions (eg, depression). Although participants easily understood time management, application of other behavioral modification techniques was more difficult. A breast cancer diagnosis alone is not sufficient for commonality among group members. Teaching time management and positive reframing is essential. Protocols for appropriate mental health referrals are needed. Our observations will assist group facilitators in enhancing group dynamics and addressing obstacles hindering counseling effectiveness. Moreover, our results suggest hypotheses related to enhancing behavior change in a group setting worthy of future study.

We developed a hospital-based cardiopulmonary resuscitation (CPR) training model focused on the target population (family members of patients with potential risks for cardiac arrest) and compared the outcome of CPR training between target and non-target populations for validity. Family members of patients in training were divided into three groups on the basis of patients' diseases, as follows: 1) the cardio-specific (CS) risk group, including family members of patients with cardiac disease at risk of cardiac arrest; 2) the cardiovascular (CV) risk group, including family members of patients with risk factors for cardiovascular disease; and 3) the no-risk group. Pre- and posttraining surveys and skill tests as well as a post-training 3-month telephone survey were conducted. Educational outcomes were analyzed. A total of 203 family members were enrolled into 21 CPR training classes. The CS group (n=88) included elderly persons and housewives with a lower level of education compared with the CV (n=79) and no-risk groups (n=36). The CS group was motivated by healthcare professionals and participated in the training course. The CS, CV, and no-risk groups showed improvements in knowledge, willingness to perform CPR, and skills. Despite the older age and lower level of education in the CS group, the effects of education were similar to those in the other groups. A high rate of response and secondary propagation of CPR training were observed in the CS group. Family members of patients with heart disease could be an appropriate target population for CPR training, particularly in terms of recruitment and secondary propagation. Targeted intervention may be an effective training strategy to improve bystander CPR rates.

Numerous studies have confirmed that brain tumor patients and their family members frequently exhibit negative emotional reactions, such as anxiety and depression, during diagnosis and treatment of the disease. Family members experience increasing pressure as the year of survival of patient progress. The aim of this study was to investigate the effects of the continued psychological care (CPC) toward the brain tumor patients and their family members' emotions. The asynchronous clinical control trial was performed, and 162 brain tumor patients and their family members were divided into the control group and the intervention group. The control group was only performed the telephone follow-up toward the patients. Beside this way, the intervention group was performed the CPC toward the patients and their family member. The self-rating anxiety scale (SAS) and the self-rating depression scale (SDS) were used to measure the negative emotions of the patients and their family members, and the patients' treatment compliance and the incidence of seizures were compared. The SAS and SDS scores of the intervention group on the 14 days, 28 days and 3 months of the CPC were significantly lower than the control group (P < 0.05); the SAS and SDS scores of the intervention group after the intervention were significantly lower than those at the discharging (P < 0.05), the treatment compliance of the intervention group was significantly higher than the control group (P < 0.05), and the seizure incidence of the intervention group was significantly lower than the control group (P < 0.05). The CPC could effectively reduce the anxiety and depression among the brain tumor patients and their family members.

We investigate the extent to which minority group members are surrounded by outgroup members in their immediate environment as a predictor of social dominance orientation. Using a large representative sample of New Zealanders, we found that minority group members in outgroup dense environments reported lower levels of social dominance orientation (Study 1). In studies 2 and 3, Asian Australian and Black American participants who were surrounded by outgroup members reported lower social dominance orientation. For majority group (White) participants there was no association between social dominance orientation and outgroup density. Study 4 explained the overall pattern: Black Americans surrounded by outgroup members perceived their group to be of lower status in their immediate environment, and through this, reported lower social dominance orientation. This article adds to growing literature on contextual factors that predict social dominance orientation, especially among minority group members.

The Institutional Approach for Modeling the Evolution of Human Societies.

PubMed

Powers, Simon T

2018-01-01

Artificial life is concerned with understanding the dynamics of human societies. A defining feature of any society is its institutions. However, defining exactly what an institution is has proven difficult, with authors often talking past each other. This article presents a dynamic model of institutions, which views them as political game forms that generate the rules of a group's economic interactions. Unlike most prior work, the framework presented here allows for the construction of explicit models of the evolution of institutional rules. It takes account of the fact that group members are likely to try to create rules that benefit themselves. Following from this, it allows us to determine the conditions under which self-interested individuals will create institutional rules that support cooperation-for example, that prevent a tragedy of the commons. The article finishes with an example of how a model of the evolution of institutional rewards and punishments for promoting cooperation can be created. It is intended that this framework will allow artificial life researchers to examine how human groups can themselves create conditions for cooperation. This will help provide a better understanding of historical human social evolution, and facilitate the resolution of pressing societal social dilemmas.

2015-03-01

In order to relieve intractable suffering of a terminal patient, doctors may decide to continuously sedate a patient until the end of life. Little research is done on the role the family plays during the process of continuous sedation. This study aims to get a view of doctors' experiences with continuous sedation, and the role of the family throughout that process. We held in-depth interviews with 48 doctors (19 general practitioners, 16 nursing home doctors and 18 medical specialists). Participants were selected varying in experience and opinions concerning end-of-life decisions. Dutch physicians experience the role of family in continuous sedation as important and potentially difficult. Difficulties may rise especially during the final stages when the patient is no longer conscious and family members are waiting for death to come. Disagreement may arise between physician and family, concerning the dignity of the dying process or the question whether the sedated patient is suffering or not. Some physicians report they hastened the dying process, in order to relieve the families' suffering. Published by the BMJ Publishing Group Limited.

With new spectroscopic observations of group candidates around the giant radio galaxy DA 240, we have identified five new group members, increasing the number to twenty-five. While all the new members are located some distance from the host galaxy, two of them lie in one of the radio lobes, and the rest are found at a distance from the radio components. The new group members reinforce our earlier conclusion that the distribution of the DA 240 group with respect to the radio lobes is unusual among giant radio galaxy host environments.

Patient and family member perceptions of physical therapy (PT) in the intensive care unit and the factors that influence their degree of satisfaction have not been described. A panel of experts developed a questionnaire that assessed patient and family perceptions of PT. Critically ill patients and their family members were asked to complete the survey. Patient and family member scores were compared and stratified by age, sex, and mechanical ventilation for greater than 14 days compared to 14 days or less. A total of 55 patients and 49 family members completed the survey. Patients and family members reported that PT was necessary and beneficial to recovery, despite associating PT with difficulty, exertion, and discomfort. Patient perceptions were similar regardless of age or sex. Family members underestimated a patient's enjoyment of PT (P = .03). For individuals who required prolonged mechanical ventilation (>14 days), patients reported that PT was more difficult (P = .03) and less enjoyable (P = .049), and family members reported PT as causing greater discomfort (P = .005). In addition, family members of patients who required prolonged mechanical ventilation felt that PT was less beneficial (P = .01). Physical therapy is perceived as necessary and beneficial to recovery by critically ill patients and family members. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim of this concept analysis is to clarify military service members' stigma associated with seeking mental health services (MHS). Since 2001, over 2 million military service members have been deployed for or assigned to support military operations. Many service members develop a mental health concern during or after a deployment. Although researchers have assessed perceptions of stigma associated with accessing MHS, defining stigma is difficult, and conceptual clarity regarding stigma is lagging behind studies focused on its effects. Stigma was explored using Walker and Avant's method of concept analysis. Thirty articles were found in the PsycARTICLES, PsycINFO, and PubMed databases and selected for inclusion and synthesis. Military service member stigma is a set of beliefs, based on the member's military and prior civilian enculturation, that seeking MHS would be discrediting or embarrassing, cause harm to career progression, or cause peers or superiors to have decreased confidence in the member's ability to perform assigned duties. Nurses are ideally suited and situated to play an important role in decreasing stigma inhibiting service members from seeking MHS. Healthcare providers and civilian and uniformed leaders must communicate the value of seeking MHS to ensure service members' health, unit readiness, and overall force preparedness. © 2016 Wiley Periodicals, Inc.

When standards are wide of the mark: nonselective superiority and inferiority biases in comparative judgments of objects and concepts.

People are frequently required to judge how particular group members measure up against others in their group. According to the local-comparisons-general-standards (LOGE) approach, in these member-to-group comparisons, people fail to use the normatively appropriate local (group) standard and are infelicitously affected by a more general standard (involving instances from outside the judged group). Within positive groups, target group members are judged superior to the other members of the group, and within negative groups, inferior. To date, these nonselective superiority and inferiority biases have been demonstrated solely in judgments about human beings. In 6 experiments, nonselective biases were found in perceptual, affective, and cognitive judgments of nonhuman targets, objects, and concepts, thus supporting a cognitive rather than a social account.

Excluding interlopers from asteroid families

NASA Astrophysics Data System (ADS)

Novakovic, B.; Radovic, V.

2014-07-01

Introduction: Asteroid families are believed to have originated from catastrophic collisions among asteroids. They are a very important subject of Solar System investigation, because practically any research topic carried out in asteroid-related science sooner or later encounters problems pertaining to asteroid families. One basic problem encountered when dealing with families is to determine reliably the list of its members, i.e. to reduce the number of interlopers as much as possible. This is an important problem, because many conclusions derived from analyses of the physical properties of family members must be necessarily based on firm and well established membership. However, as the number of known asteroids increases fast it becomes more and more difficult to obtain robust list of members of an asteroid family. To cope with these challenges we are proposing a new approach that may help to significantly reduce presence of interlopers among the family members. This method should be particularly useful once additional information become available, including primarily spectro-photometric data. This is exactly the kind of information that will be provided by Gaia. Metodology: Families (and their members) have been commonly identified by analysing the distribution of asteroids in the space of proper orbital elements, using the Hierarchical Clustering Method (HCM) [1]. A well-known drawback of the HCM based on the single linkage rule is the so-called chaining phenomenon: first concentrations naturally tend to incorporate nearby groups, forming a kind of 'chain'. Thus, any family membership obtained by the pure HCM must unavoidably include some interlopers. The method we are proposing here could be used to identify these interlopers, with its main advantage being an ability to significantly reduce the chaining effect. The method consists of three main steps. First we determine an asteroid family members by applying the HCM to the catalogue of proper elements obtained from AstDys database. Next, all family members that do not meet adopted criteria (based on physical and spectral characteristics) are excluded from the initial catalogue. Finally, the HCM analysis is performed again using the improved catalogue. Results: We apply this approach to the Themis family. In the first step the HCM links 3061 asteroids to the family. Among them we identify 113 potential interlopers. After removing interlopers, in the second run of the HCM, the total number of members has decreased to 2847. Thus, 101 extra objects have been excluded from the membership list (see Figure).

Summary Serology, defined as antibody-based diagnostics, has been regarded as the diagnostic gold standard in transfusion medicine. Nowadays however the impact of molecular diagnostics in transfusion medicine is rapidly growing. Molecular diagnostics can improve tissue typing (HLA typing), increase safety of blood products (NAT testing of infectious diseases), and enable blood group typing in difficult situations (after transfusion of blood products or prenatal non-invasive RhD typing). Most of the molecular testing involves the determination of the presence of single nucleotide polymorphisms (SNPs). Antigens (e.g. blood group antigens) mostly result from single nucleotide differences in critical positions. However, most blood group systems cannot be determined by looking at a single SNP. To identify members of a blood group system a number of critical SNPs have to be taken into account. The platforms which are currently used to perform molecular diagnostics are mostly gel-based, requiring time-consuming multiple manual steps. To implement molecular methods in transfusion medicine in the future the development of higher-throughput SNP genotyping non-gel-based platforms which allow a rapid, cost-effective screening are essential. Because of its potential for automation, high throughput and cost effectiveness the special focus of this paper is a relative new technique: SNP genotyping by MALDI-TOF MS analysis. PMID:21113259

Is There a War on Women in Psychoanalysis? The Disappearance of a Group of Women Leaders.

PubMed

Notman, Malkah T

2015-01-01

Some older members of the Boston Psychoanalytic Society remarked that in the 1950s and 1960s there was a group of prominent women analytic leaders at BPSI. They were training analysts, writers, and teachers active in the society and in the community. They were succeeded primarily by men. The question arose Was that an expression of "the war on women"? This paper explores and discusses this question. Although there were some expressions of resentment at being "dominated" by women, the answer appears to be more complex. For various reasons there was not a group of younger women available to move into this role at that time. The reasons for this are described--including the need for a medical degree for psychoanalytic training, the cultural postwar pressures in the United States for women not to work, and the institutional structural problems making it difficult for women candidates, such as ambivalence about pregnancy and the delays in changes in theory to enter the curriculum. This made for discrepancies between theory and the experience of candidates. The earlier group of women were mostly trained in Europe and the implications of this are described. In the years when the leadership was primarily male, decisions subtly reflected this.

Study on axial strength of a channel-shaped pultruded GFRP member

Fiber reinforced polymers (FRP) are widely used in vehicle and aerospace applications because of their lightweight and high-strength characteristics. Additionally, FRPs are increasingly applied to building structures. However, the elastic modulus of glass fiber reinforced polymers (GFRPs) is lower than that of steel. Hence, the evaluating the buckling strength of GFRP members for design purpose is necessary. The buckling strength is determined by Euler buckling mode as well as local buckling. In this study investigated the compressive strength of GFRP members subjected to axial compression through experiments and theoretical calculations. The adopted GFRP member was a channel-shaped GFRP, which was molded via pultrusion, at various lengths. Although, the mechanical properties as longitudinal elastic modulus and fiber volume fraction and strength of GFRP members subjected, to axial can be easily evaluated, evaluating transverse elastic modulus and shear modulus in typical material tests is difficult in standard section. Therefore the composite law was used in this study. As a result, we confirmed that the axial strength of a GFRP member could be calculated by a theoretical evaluation method utilizing longitudinal elastic modulus and fiber volume fraction.

Economic and other barriers to adopting recommendations to prevent childhood obesity: results of a focus group study with parents

PubMed Central

2009-01-01

Background Parents are integral to the implementation of obesity prevention and management recommendations for children. Exploration of barriers to and facilitators of parental decisions to adopt obesity prevention recommendations will inform future efforts to reduce childhood obesity. Methods We conducted 4 focus groups (2 English, 2 Spanish) among a total of 19 parents of overweight (BMI ≥ 85th percentile) children aged 5-17 years. The main discussion focused on 7 common obesity prevention recommendations: reducing television (TV) watching, removing TV from child's bedroom, increasing physically active games, participating in community or school-based athletics, walking to school, walking more in general, and eating less fast food. Parents were asked to discuss what factors would make each recommendation more difficult (barriers) or easier (facilitators) to follow. Participants were also asked about the relative importance of economic (time and dollar costs/savings) barriers and facilitators if these were not brought into the discussion unprompted. Results Parents identified many barriers but few facilitators to adopting obesity prevention recommendations for their children. Members of all groups identified economic barriers (time and dollar costs) among a variety of pertinent barriers, although the discussion of dollar costs often required prompting. Parents cited other barriers including child preference, difficulty with changing habits, lack of information, lack of transportation, difficulty with monitoring child behavior, need for assistance from family members, parity with other family members, and neighborhood walking safety. Facilitators identified included access to physical activity programs, availability of alternatives to fast food and TV which are acceptable to the child, enlisting outside support, dietary information, involving the child, setting limits, making behavior changes gradually, and parental change in shopping behaviors and own eating behaviors. Conclusions Parents identify numerous barriers to adopting obesity prevention recommendations, most notably child and family preferences and resistance to change, but also economic barriers. Intervention programs should consider the context of family priorities and how to overcome barriers and make use of relevant facilitators during program development. PMID:20025769

Members' needs, intragroup conflict, and group performance.

2014-05-01

Focusing on "what people want in their group" as a critical antecedent of intragroup conflict, the present study theorizes and empirically investigates the relationships among the psychological needs of group members, intragroup conflict, and group performance. It attends to the within-group average and dispersion of members' psychological needs and examines the effects stemming from group composition of needs on multiple types of conflict. The analyses based on multisource data from 145 organizational teams revealed significant relationships between the groups' composition with respect to the members' need for achievement and task conflict, need for affiliation and relationship conflict, and need for power and status conflict. Some of these relationships were moderated by open communication among members. The analyses also demonstrated that when the 3 types of conflict were considered together, task conflict was a positive predictor of group performance, whereas relationship conflict was a negative predictor. The findings highlight the motivational aspects of intragroup conflict, revealing the multilevel dynamics of the psychological needs in social settings. (c) 2014 APA, all rights reserved.

The influence of group membership on cross-contextual imitation.

PubMed

Genschow, Oliver; Schindler, Simon

2016-08-01

Research on mimicry has demonstrated that individuals imitate in-group members more strongly than out-group members. In the present study, we tested whether such top-down modulation also applies for more extreme forms of direct mapping, such as for cross-contextual imitation settings, in which individuals imitate others' movements without sharing a common goal or context. Models on self-other control suggest that top-down modulations are based merely on a direct link between social sensory processing and imitation. That is, perceived similarities between oneself and another person is sufficient to amplify a shared representation between own and others' actions, which then trigger imitation. However, motivational accounts explain such findings with the assumption that individuals are motivated to affiliate with others. Because imitation is linked to positive social consequences, individuals should imitate in-group members more strongly than out-group members. We tested these two theoretical accounts against each other by applying a cross-contextual imitation paradigm. The results demonstrate that in-group members are more strongly cross-contextually imitated than out-group members the higher individuals' motivation to affiliate with the in-group is. This supports motivational models but not self-other control accounts. Further theoretical implications are discussed.

We present a spectroscopic and kinematic analysis of 79 nearby M dwarfs in 77 systems. All of these dwarfs are low-proper-motion southern hemisphere objects and were identified in a nearby star survey with a demonstrated sensitivity to young stars. Using low-resolution optical spectroscopy from the Red Side Spectrograph on the South African Large Telescope, we have determined radial velocities, H-alpha, lithium 6708 Å, and potassium 7699 Å equivalent widths linked to age and activity, and spectral types for all of our targets. Combined with astrometric information from literature sources, we identify 44 young stars. Eighteen are previously known members ofmore » moving groups within 100 pc of the Sun. Twelve are new members, including one member of the TW Hydra moving group, one member of the 32 Orionis moving group, 9 members of Tucana-Horologium, one member of Argus, and two new members of AB Doradus. We also find 14 young star systems that are not members of any known groups. The remaining 33 star systems do not appear to be young. This appears to be evidence of a new population of nearby young stars not related to the known nearby young moving groups.« less

Inderbitzin, Michelle

2007-06-01

This article is based on an ethnographic study of a cottage for violent offenders in one state's maximum-security training school. Staff members working in the cottage were the institution's front line in its attempts to hold the youth accountable for their crimes while also trying to resocialize and rehabilitate young men who were growing up with few conforming role models. As such, cottage staff members were put in the difficult position of juggling their roles as corrections officers, counselors, and surrogate parents. To effectively do their job, they had to find ways to balance the rhetoric of rehabilitation with the punitive reality of daily life in the institution. This article details the juvenile justice career paths of the staff members in the cottage and provides a sociological analysis of the roles, responsibilities, and interactions of the staff members with each other and with the young men in their care.

An automatic approach to exclude interlopers from asteroid families

2017-09-01

Asteroid families are a valuable source of information to many asteroid-related researches, assuming a reliable list of their members could be obtained. However, as the number of known asteroids increases fast it becomes more and more difficult to obtain a robust list of members of an asteroid family. Here, we are proposing a new approach to deal with the problem, based on the well-known hierarchical clustering method. An additional step in the whole procedure is introduced in order to reduce a so-called chaining effect. The main idea is to prevent chaining through an already identified interloper. We show that in this way a number of potential interlopers among family members is significantly reduced. Moreover, we developed an automatic online-based portal to apply this procedure, I.e. to generate a list of family members as well as a list of potential interlopers. The Asteroid Families Portal is freely available to all interested researchers.

Young people's social standing among friends and peers has been linked to general levels of drinking and has been shown to influence others' drinking. We extend previous research by examining young adults' status within their natural-occurring drinking groups as a predictor of their subsequent alcohol consumption and encouragement of group members' alcohol consumption during a night out at licensed drinking establishments, a salient context for heavy drinking and alcohol-related risk among young adults. We recruited same-sex young adult drinking groups (n = 104 groups; 63 all-male; average group size = 3.4 members; Mage = 21.86) on their way to drinking establishments to complete a survey-containing measures of member-nominated within-group status, likeability, and self-reported alcohol consumption-and a breathalyzer test. At the end of the evening, participants completed the same alcohol consumption measures and were asked to nominate group members who encouraged other members to drink that night. Multilevel analysis revealed that higher-status members engaged in the most alcohol consumption (via both self-report and breathalyzer) but in heavier drinking groups only. Higher-status members also encouraged the most alcohol consumed by others, regardless of levels of group drinking. Further, even though being liked by one's peers was positively related to intoxication that night, it did not account for the significant relationship between within-group status and drinking. Results suggest that peer-related prevention programs for young adults' problem drinking may benefit from focusing on the structure and dynamic of young people's drinking groups. Also, programs targeting peer norms may be more successful if they incorporate status-related issues. Copyright © 2013 by the Research Society on Alcoholism.

The Chains on All My People Are the Chains on Me: Restrictions to Collective Autonomy Undermine the Personal Autonomy and Psychological Well-Being of Group Members.

Four studies assessed the potentially detrimental effects that restrictions to collective autonomy (i.e., a group's freedom to determine and practice its own identity) may have for the personal autonomy and psychological well-being of group members. In Study 1, using 3 distinct samples (NSample1a = 123, NSample1b = 129, NSample1c = 370), correlational and cross-cultural evidence indicates that perceived restrictions to the collective autonomy of one's group is directly associated with reduced personal autonomy, and indirectly associated with diminished well-being through personal autonomy. In Study 2 (N = 411), a longitudinal assessment of group members over 3 time-points during a 4-month period found that group members who perceived greater collective autonomy restriction also experienced reduced personal autonomy, and in turn, reduced psychological well-being over time. In Study 3 (N = 255), group members described a time during which their ingroup had (or did not have) its collective autonomy unduly restricted by other groups. Participants who were primed to think that their group lacked collective autonomy reported reduced feelings of personal autonomy, and reduced psychological well-being (compared with those primed to think their group had collective autonomy). In Study 4 (N = 389), collective autonomy was manipulated within the context of an intensive laboratory simulation. Collective autonomy-restricted group members experienced less personal autonomy than those who did not have their collective autonomy restricted. Together these findings suggest that restrictions to a group's collective autonomy may have detrimental consequences for the personal autonomy and psychological well-being of group members.

Identifying geochemical processes using End Member Mixing Analysis to decouple chemical components for mixing ratio calculations

NASA Astrophysics Data System (ADS)

Pelizardi, Flavia; Bea, Sergio A.; Carrera, Jesús; Vives, Luis

2017-07-01

Mixing calculations (i.e., the calculation of the proportions in which end-members are mixed in a sample) are essential for hydrological research and water management. However, they typically require the use of conservative species, a condition that may be difficult to meet due to chemical reactions. Mixing calculation also require identifying end-member waters, which is usually achieved through End Member Mixing Analysis (EMMA). We present a methodology to help in the identification of both end-members and such reactions, so as to improve mixing ratio calculations. The proposed approach consists of: (1) identifying the potential chemical reactions with the help of EMMA; (2) defining decoupled conservative chemical components consistent with those reactions; (3) repeat EMMA with the decoupled (i.e., conservative) components, so as to identify end-members waters; and (4) computing mixing ratios using the new set of components and end-members. The approach is illustrated by application to two synthetic mixing examples involving mineral dissolution and cation exchange reactions. Results confirm that the methodology can be successfully used to identify geochemical processes affecting the mixtures, thus improving the accuracy of mixing ratios calculations and relaxing the need for conservative species.

Comparison of 12-step Groups to Mutual Help Alternatives for AUD in a Large, National Study: Differences in Membership Characteristics and Group Participation, Cohesion, and Satisfaction

Background Many studies suggest that participation in 12-step groups contributes to better recovery outcomes, but people often object to such groups and most do not sustain regular involvement. Yet, research on alternatives to 12-step groups is very sparse. The present study aimed to extend the knowledge base on mutual help group alternatives for those with an alcohol use disorder (AUD), sampling from large, active, abstinence-focused groups including Women for Sobriety (WFS), LifeRing, and SMART Recovery (SMART). This paper presents a cross-sectional analysis of this longitudinal study, using baseline data to describe the profile and participation characteristics of attendees of these groups in comparison to 12-step members. Methods Data from participants 18 and over with a lifetime AUD (N=651) were collected using web-based surveys. Members of alternative 12-step groups were recruited in collaboration with group directors, who helped publicize the study by emailing meeting conveners and attendees and posting announcements on social media. A comparison group of current (past-30-day) 12-step attendees was recruited from an online meeting hub for recovering persons. Interested parties were directed to a webpage where they were screened, and eligible participants completed an online survey assessing demographic and clinical variables; in-person and online mutual help involvement; and group satisfaction and cohesion. Analyses involved comparing those identifying WFS, SMART, and LifeRing as their primary group to 12-step members on the above characteristics. Results Compared to 12-step members, members of the mutual help alternatives were less religious and generally higher on education and income. WFS and LifeRing members were also older, more likely to be married, and lower on lifetime drug and psychiatric severity; meanwhile, LifeRing and SMART members were less likely to endorse the most stringent abstinence goal. Finally, despite lower levels of in-person meeting attendance, members of all the 12-step alternatives showed equivalent activity involvement and higher levels of satisfaction and cohesion, compared to 12-step members. Conclusions Results suggest differences across 12-step groups and their alternatives that may be relevant when advising clients on a choice of mutual help group. Meanwhile, findings for high levels of participation, satisfaction, and cohesion among members of the mutual help alternatives suggest promise for these groups in addressing addiction problems.

2017-10-01

This study contributes to emerging literature on online health networks by modeling communication patterns between members of a moderated online support group for problem drinking. Using social network analysis, we described members' patterns of joint participation in threads, parsing out the role of site moderators, and explored differences in member characteristics by network position. Posts made to the online support group of Alcohol Help Centre during 2013 were structured as a two-mode network of members (n = 205) connected via threads (n = 506). Metrics included degree centrality, clique membership, and tie strength. The network consisted of one component and no cliques of members, although most made few posts and a small number communicated only with the site's moderators. Highly active members were older and tended to have started posting prior to 2013. The distribution of members across threads varied from threads containing posts by one member to others that connected multiple members. Moderators accounted for sizable proportions of the connectivity between both members and threads. After 5 years of operation, the AHC online support group appears to be fairly cohesive and stable, in the sense that there were no isolated subnetworks comprised of specific types of members or devoted to specific topics. Participation and connectedness at the member-level was varied, however, and tended to be low on average. The moderators were among the most central in the network, although there were also members who emerged as central and dedicated contributors to the online discussions across topics. Study findings highlight a number of areas for consideration by online support group developers and managers.

Mastering moral misery: Emotional and coping responses to intragroup morality (vs. competence) evaluations.

PubMed

van der Lee, Romy; Ellemers, Naomi; Scheepers, Daan

2016-01-01

In social groups, individuals are often confronted with evaluations of their behaviour by other group members and are motivated to adapt their own behaviour accordingly. In two studies we examine emotional responses towards, and perceived coping abilities with, morality vs. competence evaluations individuals receive from other in-group members. In Study 1, we show that evaluations of one's immoral behaviour primarily induce guilt, whereas evaluations of incompetent behaviour raise anger. In Study 2, we elaborate on the psychological process associated with these emotional responses, and demonstrate that evaluations of immorality, compared to incompetence, diminish group members' perceived coping abilities, which in turn intensifies feelings of guilt. However, when anticipating an opportunity to restore one's self-image as a moral group member, perceived coping abilities are increased and the experience of guilt is alleviated. Together these studies demonstrate how group members can overcome their moral misery when restoring their self-image.

Development of structural schemes of parallel structure manipulators using screw calculus

Rashoyan, G. V.; Shalyukhin, K. A.; Gaponenko, EV

2018-03-01

The paper considers the approach to the structural analysis and synthesis of parallel structure robots based on the mathematical apparatus of groups of screws and on a concept of reciprocity of screws. The results are depicted of synthesis of parallel structure robots with different numbers of degrees of freedom, corresponding to the different groups of screws. Power screws are applied with this aim, based on the principle of static-kinematic analogy; the power screws are similar to the orts of axes of not driven kinematic pairs of a corresponding connecting chain. Accordingly, kinematic screws of the outlet chain of a robot are simultaneously determined which are reciprocal to power screws of kinematic sub-chains. Solution of certain synthesis problems is illustrated with practical applications. Closed groups of screws can have eight types. The three-membered groups of screws are of greatest significance, as well as four-membered screw groups [1] and six-membered screw groups. Three-membered screw groups correspond to progressively guiding mechanisms, to spherical mechanisms, and to planar mechanisms. The four-membered group corresponds to the motion of the SCARA robot. The six-membered group includes all possible motions. From the works of A.P. Kotelnikov, F.M. Dimentberg, it is known that closed fifth-order screw groups do not exist. The article presents examples of the mechanisms corresponding to the given groups.

Neuroergonomics: Quantitative Modeling of Individual, Shared, and Team Neurodynamic Information.

Stevens, Ronald H; Galloway, Trysha L; Willemsen-Dunlap, Ann

2018-06-01

The aim of this study was to use the same quantitative measure and scale to directly compare the neurodynamic information/organizations of individual team members with those of the team. Team processes are difficult to separate from those of individual team members due to the lack of quantitative measures that can be applied to both process sets. Second-by-second symbolic representations were created of each team member's electroencephalographic power, and quantitative estimates of their neurodynamic organizations were calculated from the Shannon entropy of the symbolic data streams. The information in the neurodynamic data streams of health care ( n = 24), submarine navigation ( n = 12), and high school problem-solving ( n = 13) dyads was separated into the information of each team member, the information shared by team members, and the overall team information. Most of the team information was the sum of each individual's neurodynamic information. The remaining team information was shared among the team members. This shared information averaged ~15% of the individual information, with momentary levels of 1% to 80%. Continuous quantitative estimates can be made from the shared, individual, and team neurodynamic information about the contributions of different team members to the overall neurodynamic organization of a team and the neurodynamic interdependencies among the team members. Information models provide a generalizable quantitative method for separating a team's neurodynamic organization into that of individual team members and that shared among team members.

2011-03-01

It has been reported that many system engineers must work hard to produce computer systems, and some of them suffer from health impairment due to their hard work. The purpose of the present cross-sectional study was to investigate the situation of impaired health status of system engineers in projects with high job strain. Countermeasures against health impairment of the subjects in the projects with high job strain in practices of occupational health fields are discussed. The study subjects were five superiors and their 35 subordinates working on computer system projects with high job strain at a large computer systems corporation in the Tokyo area. The control group was comprised of three superiors and their 18 subordinates in the same corporation. From July to November, 2006, the above were interviewed by six occupational health nurses, who evaluated their health and recorded their health evaluation scores. The problems involved in producing the computer systems were sometimes very difficult to solve, even if they spent long hours working on them. The present study detected a tendency showing that healthy superiors' subordinates were unhealthy and unhealthy superiors' subordinates were healthy in the overload projects with high job strain, while this was not detected in the control groups. A few employees whose health deteriorated were faced with very hard jobs in the overload projects. This means that heavy workloads were unevenly distributed in the overload projects among superiors, and their subordinates, and the health of a few members with heavy workloads deteriorated due to the heavy workload. In order to improve such a situation, it may be important not only to commit the necessary number of employees whose working ability is high to the section but also to even the workload in the overload project by informing all members of the project the health impairment of a few members due to heavy workload, from the viewpoint of the practice of occupational health and risk management.

Stakeholders’ Views on Barriers to Research on Controversial Controlled Substances

2017-01-01

Many diseases and disease symptoms still lack effective treatment. At the same time, certain controversial Schedule I drugs, such as heroin and cannabis, have been reputed to have considerable therapeutic potential for addressing significant medical problems. Yet, there is a paucity of U.S. clinical studies on the therapeutic uses of controlled drugs. For example, people living with HIV/AIDS experience a variety of disease- and medication-related symptoms. Their chronic pain is intense, frequent, and difficult to treat. Nevertheless, clinical trials of compassionate management for their chronic symptoms that should be a research priority, is stymied. We employed qualitative methods to develop an understanding of the barriers to research on potential therapeutic uses of Schedule I drugs so that they might be addressed. We elicited the perspectives of key stakeholder groups that would be involved in such studies: people living with HIV/AIDS, clinicians, and Institutional Review Board members. As we identified obstacles to research, we found all stakeholder groups to arrive at the same conclusion, that clinical research on the therapeutic potential of these drugs is ethically required.

No data were available on demographic and clinical characteristics of members of fibromyalgia syndrome (FMS) self-help groups in Germany. The study was carried out from November 2010 to April 2011. A set of questionnaires was distributed by the German League Against Rheumatism and the German Fibromyalgia Association to members and to all consecutive FMS patients at nine clinical centres of different levels of care. The set included a self-developed questionnaire on demographic and medical data and on previously and currently used therapies, the patient health questionnaire (PHQ 4) and the fibromyalgia survey questionnaire. Members of FMS self-help groups (N = 1,014) were older and reported a longer duration of chronic widespread pain, less anxiety and depression and a more frequent current use of aerobic exercise, relaxation training and complementary alternative medication than participants not affiliated with FMS self-help groups (N = 630). Membership in FMS self-help groups was associated with less psychological distress and a more frequent use of active self-management strategies.

Understanding the emergence of state goal orientation in organizational work groups: the role of leadership and multilevel climate perceptions.

PubMed

Dragoni, Lisa

2005-11-01

This article attends to a broad range of practically significant employee motivations and provides insight into how to enhance individual-level performance by examining individual-level state goal orientation emergence in organizational work groups. Leadership and multilevel climate processes are theorized to parallel each dimension of state goal orientation to cue and ultimately induce the corresponding achievement focus among individual work group members. It is argued that the patterns of leader behavior, which elucidate the leader's achievement priority, shape group members' psychological and work group climate to embody this priority. Resulting multilevel climate perceptions signal and compel group members to adopt the ascribed form of state goal orientation. The quality of the leader-member exchange relationship is viewed as a means to clarify leader messages in the formation of group members' psychological climate and internalize these cues in the emergence of state goal orientation. Considerations for future research and practice are discussed. ((c) 2005 APA, all rights reserved).

Lost in the crowd: entitative group membership reduces mind attribution.

PubMed

Morewedge, Carey K; Chandler, Jesse J; Smith, Robert; Schwarz, Norbert; Schooler, Jonathan

2013-12-01

This research examined how and why group membership diminishes the attribution of mind to individuals. We found that mind attribution was inversely related to the size of the group to which an individual belonged (Experiment 1). Mind attribution was affected by group membership rather than the total number of entities perceived at once (Experiment 2). Moreover, mind attribution to an individual varied with the perception that the individual was a group member. Participants attributed more mind to an individual that appeared distinct or distant from other group members than to an individual that was perceived to be similar or proximal to a cohesive group (Experiments 3 and 4). This effect occurred for both human and nonhuman targets, and was driven by the perception of the target as an entitative group member rather than by the knowledge that the target was an entitative group member (Experiment 5).

2016-01-01

This research aims to explore the neural correlates involved in altruistic punishment, parochial altruism and anti-social punishment, using the Third-Party Punishment (TPP) game. In particular, this study considered these punishment behaviors in in-group vs. out-group game settings, to compare how people behave with members of their own national group and with members of another national group. The results showed that participants act altruistically to protect in-group members. This study indicates that norm violation in in-group (but not in out-group) settings results in increased activity in the medial prefrontal cortex and temporo-parietal junction, brain regions involved in the mentalizing network, as the third-party attempts to understand or justify in-group members' behavior. Finally, exploratory analysis during anti-social punishment behavior showed brain activation recruitment of the ventromedial prefrontal cortex, an area associated with altered regulation of emotions.

Social identity shapes social valuation: evidence from prosocial behavior and vicarious reward

PubMed Central

Hackel, Leor M.; Zaki, Jamil

2017-01-01

Abstract People frequently engage in more prosocial behavior toward members of their own groups, as compared to other groups. Such group-based prosociality may reflect either strategic considerations concerning one's own future outcomes or intrinsic value placed on the outcomes of in-group members. In a functional magnetic resonance imaging experiment, we examined vicarious reward responses to witnessing the monetary gains of in-group and out-group members, as well as prosocial behavior towards both types of individuals. We found that individuals’ investment in their group—a motivational component of social identification—tracked the intensity of their responses in ventral striatum to in-group (vs out-group) members’ rewards, as well as their tendency towards group-based prosociality. Individuals with strong motivational investment in their group preferred rewards for an in-group member, whereas individuals with low investment preferred rewards for an out-group member. These findings suggest that the motivational importance of social identity—beyond mere similarity to group members—influences vicarious reward and prosocial behavior. More broadly, these findings support a theoretical framework in which salient social identities can influence neural representations of subjective value, and suggest that social preferences can best be understood by examining the identity contexts in which they unfold.

The objective of this study was to observe trends in payer expenditures for plan members with one of 14 chronic, complex conditions comparing one group with a disease management program specific to their condition (the intervention group) and the other with no specific disease management program (the control group) for these conditions. The authors used payer claims and membership data to identify members eligible for the program in a 12-month baseline year (October 2001 to September 2002) and a subsequent 12-month program year (October 2002 to September 2003). Two payers were analyzed: one health plan with members primarily in New Jersey (AmeriHealth New Jersey [AHNJ]), where the disease management program was offered, and one affiliated large plan with members primarily in the metro Philadelphia area, where the program was not offered. The claims payment policy for both plans is identical. Intervention and control groups were analyzed for equivalence. The analysis was conducted in both groups over identical time periods. The intervention group showed statistically significant (p < 0.01) differences in total paid claims trend and expenditures when compared to the control group. Intervention group members showed a reduction in expenditures of -8%, while control group members showed an increase of +10% over identical time periods. Subsequent analyses controlling for outliers and product lines served to confirm the overall results. The disease management program is likely responsible for the observed difference between the intervention and control group results. A well-designed, targeted disease management program offered by a motivated, supportive health plan can play an important role in cost improvement strategies for members with complex, chronic conditions.

Adolescent cough medicine abuse in Hong Kong: implications for the design of positive youth development programs in Hong Kong.

2006-01-01

This study examines the phenomenon of adolescent cough medicine abuse in Hong Kong. Quantitative data obtained from questionnaire survey with 225 adolescents showed that there were personal, peer, family and community factors influencing adolescent cough medicine abuse. Part 2 of the study obtained qualitative data from focus group interviews with cough medicine abusers (N = 8), their family members (N = 5) and service providers (N = 6). The accounts of the participants revealed that the primary factors accounting for adolescent cough medicine abuse were social pressure (peer and environmental influences), family (difficult relationships or harmful incidents), availability (ease of access), and ignorance (unaware of the consequence of cough medicine use and belief that cough medicine was non-addictive). The present findings provide useful pointers for the development of the positive youth development program supported by the Hong Kong Jockey Club Charities Trust.

Physicians, once only responsible for patient care, now are responsible for their organization's management. Although this paradigm shift occasioned much opposition, most aspects of this change are improving as the rules are reevaluated and reconsidered. Physician managers have difficult tasks for which medical school provides no preparation. Employees must be individually evaluated, so their unique talents can be properly exploited and appropriately compensated. Each person's weaknesses must be improved upon with delicacy, while his or her strengths are given greater and greater focus. This is especially true with regards to billing and coding because the financial health of all healthcare businesses requires organizational competence in this arena. It is vital to have an understanding of each staff member's skills, talents, and knowledge, and a proper deployment of each person into the appropriate job. The goal of any manager is a group of satisfied employees who enjoy their work and make appropriately recognized contributions.

Cancer diagnosis not only shakes the lives of those who are affected, but also has impacts on the entire family system, which is involved as if it were itself an organism affected by cancer. The oncological illness may cause a breakdown of the existing balance in the family system and demands a progressive degree of mutual adaptation to family members. The 'VoiNoi' Listening Centre of the Campus Bio-Medico University Hospital in Rome has been close to caregivers for several years, to support them in the difficult task of providing assistance through individual or group psychological support therapy and health education. The 'Charter of Rights for Family Caregivers' stems from the experience gained over the years, with the aim of protecting, supporting and strengthening the role and the assistance activity that families carry out in support of their loved ones under conditions of fragility.

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

The American College of Cardiology Adult Congenital and Pediatric Cardiology (ACPC) Section had attempted to create quality metrics (QM) for ambulatory pediatric practice, but limited evidence made the process difficult. The ACPC sought to develop QMs for ambulatory pediatric cardiology practice. Five areas of interest were identified, and QMs were developed in a 2-step review process. In the first step, an expert panel, using the modified RAND-UCLA methodology, rated each QM for feasibility and validity. The second step sought input from ACPC Section members; final approval was by a vote of the ACPC Council. Work groups proposed a total of 44 QMs. Thirty-one metrics passed the RAND process and, after the open comment period, the ACPC council approved 18 metrics. The project resulted in successful development of QMs in ambulatory pediatric cardiology for a range of ambulatory domains. Copyright © 2017 American College of Cardiology Foundation.

This study examines variability in patterns of peer group antipathy. Same-grade adolescent peer groups were identified from sociometric nominations of preferred affiliates in a community sample of 600 Finnish 9th grade middle school students (M = 15.0 years-old). Hierarchical linear modeling determined characteristics of youth in actor groups (nominators) that predicted antipathy for youth in target groups (nominatees) on the basis of target group characteristics. Most antipathies were based on dissimilarity between groups representing the mainstream culture and groups opposed to it. The higher a peer group's school burnout, the more its members disliked students in peer groups with higher school grades and students in peer groups with higher sports participation. Conversely, the higher a peer group's school grades, the more its members disliked students in peer groups with higher school burnout. Students in peer groups with less problem behavior disliked students in peer groups with more problem behavior. There was some evidence of rivalry within the mainstream culture: The higher a group's school grades, the more its members disliked those in groups whose members participated in sports.

Group size adjustment to ecological demand in a cooperative breeder.

PubMed

Zöttl, Markus; Frommen, Joachim G; Taborsky, Michael

2013-04-07

Environmental factors can determine which group size will maximize the fitness of group members. This is particularly important in cooperative breeders, where group members often serve different purposes. Experimental studies are yet lacking to check whether ecologically mediated need for help will change the propensity of dominant group members to accept immigrants. Here, we manipulated the perceived risk of predation for dominant breeders of the cooperatively breeding cichlid fish Neolamprologus pulcher to test their response to unrelated and previously unknown immigrants. Potential immigrants were more readily accepted if groups were exposed to fish predators or egg predators than to herbivorous fish or control situations lacking predation risk. Our data are consistent with both risk dilution and helping effects. Egg predators were presented before spawning, which might suggest that the fish adjust acceptance rates also to a potential future threat. Dominant group members of N. pulcher apparently consider both present and future need of help based on ecological demand. This suggests that acceptance of immigrants and, more generally, tolerance of group members on demand could be a widespread response to ecological conditions in cooperatively breeding animals.

Disordered communication and grieving in deaf member families.

Sloman, L; Springer, S; Vachon, M L

1993-06-01

When a deaf child is born to hearing parents, a grieving process is initiated in the parents. Unresolved grieving over their child's deafness often makes it difficult for hearing parents to accept the importance of signing, thus increasing the child's problems--a further source of grief for these parents. Clinical illustrations are provided of (1) the reciprocal relationship between disruption of the mourning process and disturbance of communication between family members, and (2) the transmission of the dysfunctional relationship between hearing parents and deaf children to the subsequent relationship between the deaf children, when they reach adulthood, and their hearing children.

Innovating to integrate the intangibles into the learning Air Force.

Hazen, Benjamin T; Weigel, Fred K; Overstreet, Robert E

2014-01-01

United States federal law and other regulations require the US military services to provide professional military education to their forces. Meeting that requirement will become increasingly difficult with the absence of a federal government budget, significant cuts to defense spending, and expected future cuts to both defense spending and manpower. Additionally, the operations tempo remains high despite the withdrawal of troops from Iraq and the planned withdrawal from Afghanistan. The resulting time and budget constraints will likely make it more difficult for the services to provide every member with the opportunity to compete for positions in coveted in-residence professional military education programs. Thus, the Air Force is considering a new lifetime learning approach to professional military education. As the Air Force seeks to develop its new paradigm, we must understand what benefits of the current system should be retained and what drawbacks should be allayed. Unfortunately, there is little research in this area. We content analyze data collected from Air Force officers attending in-residence professional military education, synthesize our findings with education and technology literature, and suggest innovative technologies that can maximize the intangible benefits and minimize the drawbacks of professional military education. The blended approach we present can create a richer, more meaningful learning experience for the service member, while simultaneously lowering the cost per member and providing greater opportunity to attend in-residence professional military education.

Intergroup relations and health disparities: a social psychological perspective.

PubMed

Major, Brenda; Mendes, Wendy Berry; Dovidio, John F

2013-05-01

This article considers how the social psychology of intergroup processes helps to explain the presence and persistence of health disparities between members of socially advantaged and disadvantaged groups. Social psychological theory and research on intergroup relations, including prejudice, discrimination, stereotyping, stigma, prejudice concerns, social identity threat, and the dynamics of intergroup interactions, is reviewed and applied to understand group disparities in health and health care. Potential directions for future research are considered. Key features of group relations and dynamics, including social categorization, social hierarchy, and the structural positions of groups along dimensions of perceived warmth and competence, influence how members of high status groups perceive, feel about, and behave toward members of low status groups, how members of low status groups construe and cope with their situation, and how members of high and low status groups interact with each other. These intergroup processes, in turn, contribute to health disparities by leading to differential exposure to and experiences of chronic and acute stress, different health behaviors, and different quality of health care experienced by members of advantaged and disadvantaged groups. Within each of these pathways, social psychological theory and research identifies mediating mechanisms, moderating factors, and individual differences that can affect health. A social psychological perspective illuminates the intergroup, interpersonal, and intrapersonal processes by which structural circumstances which differ between groups for historical, political, and economic reasons can lead to group differences in health.

Objective This article considers how the social psychology of intergroup processes helps to explain the presence and persistence of health disparities between members of socially advantaged and disadvantaged groups. Method Social psychological theory and research on intergroup relations, including prejudice, discrimination, stereotyping, stigma, prejudice concerns, social identity threat, and the dynamics of intergroup interactions, is reviewed and applied to understand group disparities in health and health care. Potential directions for future research are considered. Results Key features of group relations and dynamics, including social categorization, social hierarchy, and the structural positions of groups along dimensions of perceived warmth and competence, influence how members of high status groups perceive, feel about, and behave toward members of low status groups, how members of low status groups construe and cope with their situation, and how members of high and low status groups interact with each other. These intergroup processes, in turn, contribute to health disparities by leading to differential exposure to and experiences of chronic and acute stress, different health behaviors, and different quality of health care experienced by members of advantaged and disadvantaged groups. Within each of these pathways, social psychological theory and research identifies mediating mechanisms, moderating factors, and individual differences that can affect health. Conclusions A social psychological perspective illuminates the intergroup, interpersonal, and intrapersonal processes by which structural circumstances which differ between groups for historical, political, and economic reasons can lead to group differences in health.

BACKGROUND: No study has examined the impact of vitiligo support group membership on vitiligo patient quality of life (QoL).

OBJECTIVE: We sought to examine the QoL impact of vitiligo support groups by comparing QoL and associated patient characteristics between vitiligo patients who are and are not members of a vitiligo support group.

METHODS: Members of a Henry Ford Hospital-sponsored, Southeast Michigan Vitiligo Support Group were compared to non-member vitiligo patients recruited from a previous study cohort.17 Eligible patients were asked to complete the Dermatology Life Quality Index (DLQI) and a study-specific questionnaire designed to collect relevant patient characteristics.

RESULTS: The mean DLQI scores for the support group members and non-members were similar (7.1 ± 5.4 and 6.0 ± 6.5, respectively; P-value 0.2), despite the support group members reporting more severe overall disease and increased disease severity in exposed portions of the body. The African-American: Caucasian ratio and the prevalence of unemployment were both significantly higher among the support group participants. Small sample size may have limited the study's ability to demonstrate the differences between the support group participants and the controls.

CONCLUSIONS: The similar QoL despite an increased prevalence of poorer QoL indicators among the support group participants suggests a protective effect of support group membership.

Soils are inhabited by many bacteria from phylogenetic groups that are poorly studied because representatives are rarely isolated in cultivation studies. Part of the reason for the failure to cultivate these bacteria is the low frequency with which bacterial cells in soil form visible colonies when inoculated onto standard microbiological media, resulting in low viable counts. We investigated the effects of three factors on viable counts, assessed as numbers of CFU on solid media, and on the phylogenetic groups to which the isolated colony-forming bacteria belong. These factors were inoculum size, growth medium, and incubation time. Decreasing the inoculum size resulted in significant increases in the viable count but did not appear to affect colony formation by members of rarely isolated groups. Some media that are traditionally used for soil microbiological studies returned low viable counts and did not result in the isolation of members of rarely isolated groups. Newly developed media, in contrast, resulted in high viable counts and in the isolation of many members of rarely isolated groups, regardless of the inoculum size. Increased incubation times of up to 3 months allowed the development of visible colonies of members of rarely isolated groups in conjunction with the use of appropriate media. Once isolated, pure cultures of members of rarely isolated groups took longer to form visible colonies than did members of commonly isolated groups. Using these new media and extended incubation times, we were able to isolate many members of the phyla Acidobacteria (subdivisions 1, 2, 3, and 4), Gemmatimonadetes, Chloroflexi, and Planctomycetes (including representatives of the previously uncultured WPS-1 lineage) as well as members of the subclasses Rubrobacteridae and Acidimicrobidae of the phylum Actinobacteria.

Primary care providers are well positioned to respond to the opioid crisis by providing buprenorphine/naloxone (B/N) through shared medical appointments (SMAs). Although quantitative research has been previously conducted on SMAs with B/N, the authors conducted a qualitative assessment from the patients' point of view, considering whether and how group visits provide value for patients. Twenty-five participants with opioid use disorder (OUD) who were enrolled in a weekly B/N group visit at a family medicine clinic participated in either of two 1-hour-long focus groups, which were conducted as actual group visits. Participants were prompted with the question "How has this group changed you as a person?" Data were audio-recorded and professionally transcribed and analyzed using a qualitative thematic approach, identifying common communication behaviors and resulting attitudes about the value of the group visit model. Participants demonstrated several communication behaviors that support group members in their recovery, including offering direct emotional support to others struggling with difficult experiences, making an intentional effort to probe about others' lives, venting about heavy situations, joking to lighten the mood, and expressing feelings of gratitude to the entire group. These communication behaviors appear to act as mechanisms to foster a sense of accountability, a shared identity, and a supportive community. Other demonstrated group behaviors may detract from the value of the group experience, including side conversations, tangential comments, and individual participants disproportionately dominating group time. The group visit format for delivering B/N promotes group-specific communication behaviors that may add unique value in supporting patients in their recovery. Future research should elucidate whether these benefits can be isolated from those achieved solely through medication treatment with B/N and if similar benefits could be achieved in non-primary care sites.

Netball team members, but not hobby group members, distinguish team characteristics from group characteristics.

Research on groups is often applied to sport teams, and research on teams is often applied to groups. This study investigates the extent to which individuals have distinct schemas for groups and teams. A list of team and group characteristics was generated from 250 individuals, for use in this and related research. Questions about teams versus groups carry an a priori implication that differences exist; therefore, list items were presented to new participants and were analyzed using signal detection theory, which can accommodate a finding of no detectable difference between a nominated category and similar items. Participants were 30 members from each of the following: netball teams, the general public, and hobby groups. Analysis revealed few features that set groups apart from teams; however, teams were perceived as more structured and demanding, requiring commitment and effort toward shared goals. Team and group characteristics were more clearly defined to team members than they were to other participant groups. The research has implications for coaches and practitioners.

We'll never get past the glass ceiling! Meta-stereotyping, world-views and perceived relative group-worth.

This article examines the implications of perceived negativity from members of a dominant outgroup on the world views and perceived relative group worth of members of disadvantaged groups. We hypothesized that concerns about the negative opinions a dominant outgroup is perceived to hold of the ingroup (i.e., meta-stereotypes) would undermine group members' views about societal fairness. We expected this trend to be mediated by recall of previous personal experiences of discrimination. We further hypothesized that members' views about societal fairness would predict their perception of the ingroup's worth relative to the outgroup - such that undermined views about societal fairness would be associated with lower perceived ingroup worth relative to the outgroup. Taken jointly, results from two studies using two real intergroup contexts support these hypotheses and are discussed in terms of their implications for the social mobility of members of disadvantaged groups. © 2012 The British Psychological Society.

Physicians have long had patients whom they have labeled "difficult", but little is known about how medical students perceive difficult encounters with patients. In this study, we analyzed 134 third year medical students' reflective essays written over an 18-month period about difficult student-patient encounters. We used a qualitative computerized software program, Atlas.ti to analyze students' observations and reflections. Main findings include that students described patients who were angry and upset; noncompliant with treatment plans; discussed "nonmedical" problems; fearful, worried, withdrawn, or "disinterested" in their health. Students often described themselves as anxious, uncertain, confused, and frustrated. Nevertheless, they saw themselves behaving in empathic and patient-centered ways while also taking refuge in "standard" behaviors not necessarily appropriate to the circumstances. Students rarely mentioned receiving guidance from attendings regarding how to manage these challenging interactions. These third-year medical students recognized the importance of behaving empathically in difficult situations and often did so. However, they often felt overwhelmed and frustrated, resorting to more reductive behaviors that did not match the needs of the patient. Students need more guidance from attending physicians in order to approach difficult interactions with specific problem-solving skills while maintaining an empathic, patient-centered context.

Urban Latino children's physical activity levels and performance in interactive dance video games: effects of goal difficulty and goal specificity.

To examine the effects of different levels of goal specificity and difficulty on Latino children's performance and physical activity (PA) levels in an after-school program incorporating an interactive dance program (Dance Dance Revolution [DDR]; Konami Corporation). Comparison study. Rose Park Elementary School, Salt Lake City, Utah. Ninety-eight Latino children in the first through sixth grades, aged 7 to 13 years. After the pretest, the participants were randomly assigned into 1 of the following 3 goal-setting conditions: (1) easy, (2) difficult, and (3) best effort (hereinafter referred to as do-your-best goal). Participants' PA levels were measured using piezoelectric pedometers, and steps per minute were used as the outcome variable. Participants' total points for their dance on television screens were retrieved as their performance scores. These outcome variables were assessed again 8 weeks later (posttest score). The multivariate analysis of covariance yielded a significant main effect for the goal-setting condition. Follow-up tests revealed that children who set specific (easy or difficult) goals had significantly greater increased PA levels (mean scores, 10.34 for easy and 22.45 for difficult) and DDR performance (0.011 for easy and 0.67 for difficult) than those in the do-your-best group (0.83 for PA and 0.17 for performance). In addition, children's increased PA levels in the difficult-goal group were significantly higher than those in the easy-goal group. The easy- and difficult-goal groups show a significant improvement on DDR performance. The difficult- goal group also displays the highest improvement on PA levels. Strategies to enhance children's DDR performance and PA levels are discussed in relation to the extant goal-setting literature.

Affective expressions in groups and inferences about members' relational well-being: The effects of socially engaging and disengaging emotions.

PubMed

Rothman, Naomi B; Magee, Joe C

2016-01-01

Our findings draw attention to the interpersonal communication function of a relatively unexplored dimension of emotions-the level of social engagement versus disengagement. In four experiments, regardless of valence and target group gender, observers infer greater relational well-being (more cohesiveness and less conflict) between group members from socially engaging (sadness and appreciation) versus disengaging (anger and pride) emotion expressions. Supporting our argument that social (dis)engagement is a critical dimension communicated by these emotions, we demonstrate (1) that inferences about group members' self-interest mediate the effect of socially engaging emotions on cohesiveness and (2) that the influence of socially disengaging emotion expressions on inferences of conflict is attenuated when groups have collectivistic norms (i.e., members value a high level of social engagement). Furthermore, we show an important downstream consequence of these inferences of relational well-being: Groups that seem less cohesive because of their members' proud (versus appreciative) expressions are also expected to have worse task performance.

We investigated the effects of dyadic training on medical students' resuscitation performance during cardiopulmonary resuscitation (CPR) training.We provided students with a 2-hour training session on CPR for simulated cardiac arrest. Student teams were split into double groups (Dyad training groups: Groups A and B) or Single Groups. All groups received 2 CPR simulation rounds. CPR simulation training began with peer demonstration for Group A, and peer observation for Group B. Then the 2 groups switched roles. Single Groups completed CPR simulation without peer observation or demonstration. Teams were then evaluated based on leadership, teamwork, and team member skills.Group B had the highest first simulation round scores overall (P = 0.004) and in teamwork (P = 0.001) and team member skills (P = 0.031). Group B also had the highest second simulation round scores overall (P < 0.001) and in leadership (P = 0.033), teamwork (P < 0.001), and team member skills (P < 0.001). In the first simulation, there were no differences between Dyad training groups with those of Single Groups in overall scores, leadership scores, teamwork scores, and team member scores. In the second simulation, Dyad training groups scored higher in overall scores (P = 0.002), leadership scores (P = 0.044), teamwork scores (P = 0.005), and team member scores (P = 0.008). Dyad training groups also displayed higher improvement in overall scores (P = 0.010) and team member scores (P = 0.022).Dyad training was effective for CPR training. Both peer observation and demonstration for peers in dyad training can improve student resuscitation performance.

How learning shapes the empathic brain.

2016-01-05

Deficits in empathy enhance conflicts and human suffering. Thus, it is crucial to understand how empathy can be learned and how learning experiences shape empathy-related processes in the human brain. As a model of empathy deficits, we used the well-established suppression of empathy-related brain responses for the suffering of out-groups and tested whether and how out-group empathy is boosted by a learning intervention. During this intervention, participants received costly help equally often from an out-group member (experimental group) or an in-group member (control group). We show that receiving help from an out-group member elicits a classical learning signal (prediction error) in the anterior insular cortex. This signal in turn predicts a subsequent increase of empathy for a different out-group member (generalization). The enhancement of empathy-related insula responses by the neural prediction error signal was mediated by an establishment of positive emotions toward the out-group member. Finally, we show that surprisingly few positive learning experiences are sufficient to increase empathy. Our results specify the neural and psychological mechanisms through which learning interacts with empathy, and thus provide a neurobiological account for the plasticity of empathic reactions.

Oxytocin modulates the racial bias in neural responses to others' suffering.

PubMed

Sheng, Feng; Liu, Yi; Zhou, Bin; Zhou, Wen; Han, Shihui

2013-02-01

The intergroup relationship between a perceiver and a target person influences empathic neural responses to others' suffering, which are increased for racial in-group members compared to out-group members. The current study investigated whether oxytocin (OT), a neuropeptide that has been linked to empathic concern and in-group favoritism, contributes to the racial bias in empathic neural responses. Event-related brain potentials were recorded in Chinese male adults during race judgments on Asian and Caucasian faces expressing pain or showing a neutral expression after intranasal self-administration of OT or placebo. A fronto-central positive activity at 128-188 ms (P2) was of larger amplitude in response to the pain expressions compared with the neutral expressions of racial in-group members but not of racial out-group members. OT treatment increased this racial in-group bias in neural responses and resulted in its correlation with a positive implicit attitude toward racial in-group members. Our findings suggest that OT interacts with the intergroup relationship to modulate empathic neural responses to others' suffering. Copyright © 2012 Elsevier B.V. All rights reserved.

Benefit to Family Members of Delivering Hand Massage With Essential Oils to Critically Ill Patients.

2015-09-01

In intensive care environments, patients' families are often encouraged to participate in their loved one's care; however, many family members feel anxious, depressed, and unsure about how to help patients. To determine (1) the feasibility of teaching family members a simple intervention combining hand massage with essential oils in a trauma intensive care unit and (2) an effect size for use in designing a more powerful trial. A quasi-experimental pilot study of the effect of a family-delivered touch treatment on anxiety and depression of family members of patients. Fifteen family members were assigned to a treatment group, and 15 family members were assigned to a control group. The treatment consisted of the application of hand massage with essential oils for 6 sessions. Each session lasted 5 minutes and was presented twice a day for 3 days. The 5-minute intervention was associated with positive change in anxiety and depression scores on the Hospital Anxiety and Depression Scale (HADS) among family members visiting patients. The magnitude of change (improvement) in anxiety scores within the group of treated family members was significantly greater than within family members in the control group. Administering a brief hand massage using pleasant-smelling oils to patients in an intensive care unit may reduce anxiety of family members who administer the treatment. ©2015 American Association of Critical-Care Nurses.

Enediynes are potent antitumor antibiotics that are classified as 9- or 10-membered according to the size of the enediyne core structure. However, almost nothing is known about enediyne core biosynthesis, and the determinants of 9- versus 10-membered enediyne core biosynthetic divergence remain elusive. Previous work identified enediyne-specific polyketide synthases (PKSEs) that can be phylogenetically distinguished as being involved in 9- versus 10-membered enediyne biosynthesis, suggesting that biosynthetic divergence might originate from differing PKSE chemistries. Recent in vitro studies have identified several compounds produced by the PKSE and associated thioesterase (TE), but condition-dependent product profiles make it difficult to ascertain a true catalytic difference between 9- and 10-membered PKSE-TE systems. Here we report that PKSE chemistry does not direct 9- versus 10-membered enediyne core biosynthetic divergence as revealed by comparing the products from three 9-membered and two 10-membered PKSE-TE systems under identical conditions using robust in vivo assays. Three independent experiments support a common catalytic function for 9- and 10-membered PKSEs by the production of a heptaene metabolite from: (i) all five cognate PKSE-TE pairs in Escherichia coli; (ii) the C-1027 and calicheamicin cognate PKSE-TEs in Streptomyces lividans K4-114; and (iii) selected native producers of both 9- and 10-membered enediynes. Furthermore, PKSEs and TEs from different 9- and 10-membered enediyne biosynthetic machineries are freely interchangeable, revealing that 9- versus 10-membered enediyne core biosynthetic divergence occurs beyond the PKSE-TE level. These findings establish a starting point for determining the origins of this biosynthetic divergence. PMID:20534556

An experiment on individual 'parochial altruism' revealing no connection between individual 'altruism' and individual 'parochialism'.

Is parochial altruism an attribute of individual behavior? This is the question we address with an experiment. We examine whether the individual pro-sociality that is revealed in the public goods and trust games when interacting with fellow group members helps predict individual parochialism, as measured by the in-group bias (i.e., the difference in these games in pro-sociality when interacting with own group members as compared with members of another group). We find that it is not. An examination of the Big-5 personality predictors of each behavior reinforces this result: they are different. In short, knowing how pro-social individuals are with respect to fellow group members does not help predict their parochialism.

To implement and evaluate a private Facebook group for members of a large Ontario multisite Family Health Team (FHT) to facilitate improved communication and collaboration. Program implementation and subsequent survey of team members. A large multisite FHT in Toronto, Ontario. Health professionals of the FHT. Usage patterns and self-reported perceptions of the Facebook group by team members. At the time of the evaluation survey, the Facebook group had 43 members (37.4% of all FHT members). Activity in the group was never high, and posts by team members who were not among the researchers were infrequent throughout the study period. The content of posts fell into two broad categories: 1) information that might be useful to various team members and 2) questions posed by team members that others might be able to answer. Of the 26 team members (22.6%) who completed the evaluation survey, many reported that they never logged into the Facebook page (16 respondents), and never used it to communicate with team members outside of their own site of practice (19 respondents). Only six respondents reported no concerns with using Facebook as a professional communication tool; the most frequent concerns were regarding personal and patient privacy. The use of social media by health care practitioners is becoming ubiquitous. However, the issues of privacy concerns and determining how to use social media without adding to provider workload must be addressed to make it a useful tool in health care.

[Effects of subliminal mere exposure to group members on intergroup evaluation: category evaluation measured in the Implicit Association Test (IAT)].

Kawakami, Naoaki; Yoshida, Fujio

2010-10-01

This study investigated the effects of subliminal mere exposure to ingroup or outgroup members on intergroup evaluation as measured in the Implicit Association Test (IAT). Participants first memorized the members of two groups. Then, they were assigned to either group by lot, and completed the IAT for intergroup evaluation (Time 1). In the next phase, half the participants were subliminally exposed to ingroup members and half to outgroup members. Upon completion of the exposure, the same IAT was administered at Time 2. The results showed that participants who were exposed to ingroup members evaluated the ingroup more positively at Time 2 than at Time 1. Participants who were exposed to outgroup members did not show an effect toward the outgroup. The finding that the mere exposure effect occurred only for the ingroup exposure condition suggests that unconscious awareness of the ingroup enhances the mere exposure effect.

The Wamp Spring section of the Bird Spring Group is subdivided into a basal platy limestone member, lower cliff-forming member, and upper cliff-forming member. Triticites, Schwagerina, and Schubertella kingi in the platy limestone member indicate an early Wolfcampian age. Schwagerina, Schubertella kingi, and a distinctive assemblage of brachiopods, similar to the West Texas fauna, indicate that the upper cliff-forming member is late Wolfcampian. The lower cliff-forming member is tentatively assigned to the middle Wolfcampian. The Wamp Spring sequence correlates temporally with the BSe 'formation' of the Bird Spring Group. The fossil-rich upper cliff-forming limestone member includes the new species Pontisia boodi, Crurithyris wampensis, and Calliprotonia(?) n. sp. A, as well as Hustedia culcitula, Crenispirifer(?) sp., Cenorhynchia(?) sp., Kutorginella(?) sp., marginiferids, lyssacine hexactinellid sponges, pleurotomarid and bellerophontid gastropods, cidaroid echinoids, rugose corals, cylindrical cryptostome bryozoans, and nuculids. -from Authors

A functional Kv1.2-hERG chimaeric channel expressed in Pichia pastoris

Members of the six-transmembrane segment family of ion channels share a common structural design. However, there are sequence differences between the members that confer distinct biophysical properties on individual channels. Currently, we do not have 3D structures for all members of the family to help explain the molecular basis for the differences in their biophysical properties and pharmacology. This is due to low-level expression of many members in native or heterologous systems. One exception is rat Kv1.2 which has been overexpressed in Pichia pastoris and crystallised. Here, we tested chimaeras of rat Kv1.2 with the hERG channel for function in Xenopus oocytes and for overexpression in Pichia. Chimaera containing the S1–S6 transmembrane region of HERG showed functional and pharmacological properties similar to hERG and could be overexpressed and purified from Pichia. Our results demonstrate that rat Kv1.2 could serve as a surrogate to express difficult-to-overexpress members of the six-transmembrane segment channel family. PMID:24569544

Fear acquisition and liking of out-group and in-group members: Learning bias or attention?

The present study explores the notion of an out-group fear learning bias that is characterized by facilitated fear acquisition toward harm-doing out-group members. Participants were conditioned with two in-group and two out-group faces as conditioned stimuli. During acquisition, one in-group and one out-group face was paired with an aversive shock whereas the other in-group and out-group face was presented without shock. Psychophysiological measures of fear conditioning (skin conductance and pupil size) and explicit and implicit liking exhibited increased differential responding to out-group faces compared to in-group faces. However, the results did not clearly indicate that harm-doing out-group members were more readily associated with fear than harm-doing in-group members. In contrast, the out-group face not paired with shock decreased conditioned fear and disliking at least to the same extent that the shock-associated out-group face increased these measures. Based on these results, we suggest an account of the out-group fear learning bias that relates to an attentional bias to process in-group information. Copyright © 2017 The Authors.

Group C serogroup includes members of the Orthobunyavirus genus (family Peribunyaviridae) and comprises 15 arboviruses that can be associated with febrile illness in humans. Although previous studies described the genome characterization of Group C orthobunyavirus, there is a gap in genomic information about the other viruses in this group. Therefore, in this study, complete genomes of members of Group C serogroup were sequenced or re-sequenced and used for genetic characterization, as well as to understand their phylogenetic and evolutionary aspects. Thus, our study reported the genomes of three new members in Group C virus (Apeu strain BeAn848, Itaqui strain BeAn12797 and Nepuyo strain BeAn10709), as well as re-sequencing of original strains of five members: Caraparu (strain BeAn3994), Madrid (strain BT4075), Murucutu (strain BeAn974), Oriboca (strain BeAn17), and Marituba (strain BeAn15). These viruses presented a typical genomic organization related to members of the Orthobunyavirus genus. Interestingly, all viruses of this serogroup showed an open reading frame (ORF) that encodes the putative nonstructural NSs protein that precedes the nucleoprotein ORF, an unprecedented fact in Group C virus. Also, we confirmed the presence of natural reassortment events. This study expands the genomic information of Group C viruses, as well as revalidates the genomic organization of viruses that were previously reported.

Online depression communities: members' interests and perceived benefits.

PubMed

Nimrod, Galit

2013-01-01

Most previous studies on online communities (peer-to-peer support groups) dedicated to people with depression related to members as a homogeneous group, and none examined differences between segments based on psychographic measures. Such segmentation may be most helpful in understanding members' participation patterns and explaining the benefits members gain from participation. This study aimed to explore whether members of online depression communities vary in their interests in issues discussed in the communities, and if so, whether groups with different interests also differ with regard to the benefits gained from participation. The study was based on an online survey of 793 members of 16 online depression communities. Results identified four member groups: concerned about daily living, information seekers, interested in all topics, and relatively less involved. There were very few differences between the groups in background characteristics, participation patterns, and level of depression. However, results indicated significant differences between the groups in perceived benefits, as the interested in all topics reported more "online support" and "offline improvement" than the information seekers and the relatively less involved, and more "offline improvement" than the concerned about daily living. Assuming that the reported interests reflected actual involvement in discussions of different issues, the findings suggest that combining supportive and informative discussions is more beneficial than attending to only one type of discussion, and stress the importance of informative discussions.

The contextualized self: how team-member exchange leads to coworker identification and helping OCB.

PubMed

Farmer, Steven M; Van Dyne, Linn; Kamdar, Dishan

2015-03-01

This article develops the argument that team-member exchange (TMX) relationships operate at both between- and within-group levels of analysis to influence an employee's sense of identification with coworkers in the group and their helping organizational citizenship behavior (OCB) directed at coworkers. Specifically, we propose that relatively higher quality TMX relationships of an employee as compared with other members of the group influence an employee's sense of positive uniqueness, whereas higher average level of TMX quality in the group creates a greater sense of belonging. Multilevel modeling analysis of field data from 236 bank managers and their subordinates supports the hypotheses and demonstrates 3 key findings. First, team members identify more with their coworkers when they have high relative TMX quality compared with other group members and are also embedded in groups with higher average TMX. Second, identification with coworkers is positively related to helping OCB directed toward team members. Finally, identification with coworkers mediates the interactive effect of relative TMX quality and group average TMX quality on helping. When TMX group relations allow individuals to feel a valued part of the group, but still unique, they engage in higher levels of helping. Overall moderated mediation analysis demonstrates that the mediated relationship linking relative TMX quality with helping OCB via identification with coworkers is stronger when group average TMX is high, but not present when group average TMX is low. We discuss theoretical and practical implications and recommend future research on multilevel conceptualizations of TMX. PsycINFO Database Record (c) 2015 APA, all rights reserved.

A Secure Multicast Framework in Large and High-Mobility Network Groups

NASA Astrophysics Data System (ADS)

Lee, Jung-San; Chang, Chin-Chen

With the widespread use of Internet applications such as Teleconference, Pay-TV, Collaborate tasks, and Message services, how to construct and distribute the group session key to all group members securely is becoming and more important. Instead of adopting the point-to-point packet delivery, these emerging applications are based upon the mechanism of multicast communication, which allows the group member to communicate with multi-party efficiently. There are two main issues in the mechanism of multicast communication: Key Distribution and Scalability. The first issue is how to distribute the group session key to all group members securely. The second one is how to maintain the high performance in large network groups. Group members in conventional multicast systems have to keep numerous secret keys in databases, which makes it very inconvenient for them. Furthermore, in case that a member joins or leaves the communication group, many involved participants have to change their own secret keys to preserve the forward secrecy and the backward secrecy. We consequently propose a novel version for providing secure multicast communication in large network groups. Our proposed framework not only preserves the forward secrecy and the backward secrecy but also possesses better performance than existing alternatives. Specifically, simulation results demonstrate that our scheme is suitable for high-mobility environments.

Preventing involuntary conscription and voluntary recruitment of youth into armed groups are global human rights priorities. Pathways for self-reported voluntary recruitment and the impact of voluntary recruitment on mental health have received limited attention. The objective of this study was to identify risk factors for voluntarily joining armed groups, as well as the association of conscription status and mental health. In Nepal, interviews were conducted with 258 former child soldiers who participated in a communist (Maoist) revolution. Eighty percent of child soldiers joined 'voluntarily'. Girls were 2.07 times as likely to join voluntarily (95% CI, 1.03-4.16, p =0.04). Among girls, 51% reported joining voluntarily because of personal connections to people who were members of the armed group, compared to 22% of boys. Other reasons included escaping difficult life situations (36%), inability to achieve other goals in life (28%), and an appealing philosophy of the armed group (32%). Poor economic conditions were more frequently endorsed among boys (22%) than girls (10%). Voluntary conscription was associated with decreased risk for PTSD among boys but not for girls. Interventions to prevent voluntary association with armed groups could benefit from attending to difficulties in daily life, identifying non-violent paths to achieve life goals, and challenging the political philosophy of armed groups. Among boys, addressing economic risk factors may prevent recruitment, and prevention efforts for girls will need to address personal connections to armed groups, as it has important implications for preventing recruitment through new methods, such as social media.

Sodium reduction is very important in preventing cardiovascular diseases, especially in regions with high salt intake such as Japan. One strategy for salt reduction is to raise consumer awareness of the need to reduce daily salt intake. We investigated whether cooking classes given to housewives focussing on salt reduction would influence not only their own consumption behaviour but also that of their family members. Single-blinded, cluster randomized trial. We randomly assigned housewives to participate in cooking classes focussing on salt reduction (intervention group) or lectures about a healthy lifestyle (control group). The main outcome measure was the difference in estimated daily salt intake by spot urine sampling of housewives and their family members 2 months after intervention between the groups. A total of 35 housewives and 33 family members were randomized. The mean daily salt intake was 10.00 (standard deviation [SD] 1.75) g/day in the control group (17 housewives and 15 family members) and 9.57 (SD 2.45) g/day in the intervention group (18 housewives and 18 family members) at baseline. Two months after the intervention, the mean salt intake was 10.30 (SD 1.78) g/day in the control group and 8.95 (SD 2.45) g/day in the intervention group. The mean difference was -1.19 g/day (95% confidence interval -2.29, -0.09; P = 0.034). A similar tendency was observed in the subgroups of housewives and family members. Our trial suggested that the effects of cooking classes focussing on salt reduction for housewives could be transferred to family members (UMIN-CTR: 000018870).

Groups can make better decisions than individuals when members cooperatively exchange and integrate their uniquely held information and insights. However, under conformity pressures group members are biased towards exchanging commonly known information, and away from exchanging unique information, thus undermining group decision-making quality. At the neurobiological level, conformity associates with the neuropeptide oxytocin. A double-blind placebo controlled study found no evidence for oxytocin induced conformity. Compared to placebo groups, three-person groups whose members received intranasal oxytocin, focused more on unique information (i) and repeated this information more often (ii). These findings reveal oxytocin as a neurobiological driver of group decision-making processes.

Patients who undergo surgery for cancer of the head and neck and their families face complex and difficult challenges and are at risk of anxiety and depression and inability to cope with symptom and treatment burden. Information available to support them is not flexible enough to adjust to individual need. A randomised clinical trial pre and post intervention design, comparing the use of a tailored DVD intervention, provided preoperatively and used throughout the post- operative period, with usual treatment. One hundred fifty-six individuals or partner couples will be randomly recruited into either the intervention or control group. A survey will be administered at three time points, preoperatively, post operatively and 3 months post-surgery. Anxiety and empowerment are the primary outcome measures. Qualitative data about use of the resource will be gathered by phone interview. This is the first study to rigorously evaluate the impact of a DVD intervention for this group of patients and their family members. The study will help to understand the impact of information usage on patient and family well- being and test a means by which to evaluate information and education resources for this and other cancer patient groups.

2016-01-01

Aims To develop clinical descriptions (vignettes) of life with Alzheimer’s disease (AD), we conducted focus groups of persons with AD (n = 14), family caregivers of persons with AD (n = 20), and clinicians who see persons with AD in their practices (n = 5). Methods Group participants read existing descriptions of AD and commented on the realism and comprehensibility of the descriptions. We used thematic framework analysis to code the comments into themes and develop three new vignettes to describe mild, moderate, and severe AD. Results Themes included the types of symptoms to mention in the new vignettes, plus the manner in which the vignettes should be written. Since the vignette descriptions were based on focus group participants’ first-hand knowledge of AD, the descriptions can be said to demonstrate content validity. Conclusion Members of the general public can read the vignettes and estimate their health-related quality-of-life (HRQoL) as if they had AD based on the vignette descriptions. This is especially important for economic evaluations of new AD medications, which require HRQoL to be assessed in a manner that persons with AD often find difficult to undertake. The vignettes will allow the general public to serve as a proxy and provide HRQoL estimates in place of persons with AD. PMID:27589604

Lessons from the evaluation of the UK's NHS R&D Implementation Methods Programme

PubMed Central

Soper, Bryony; Hanney, Stephen R

2007-01-01

Background Concern about the effective use of research was a major factor behind the creation of the NHS R&D Programme in 1991. In 1994, an advisory group was established to identify research priorities in research implementation. The Implementation Methods Programme (IMP) flowed from this, and its commissioning group funded 36 projects. In 2000 responsibility for the programme passed to the National Co-ordinating Centre for NHS Service Delivery and Organisation R&D, which asked the Health Economics Research Group (HERG), Brunel University, to conduct an evaluation in 2002. By then most projects had been completed. This evaluation was intended to cover: the quality of outputs, lessons to be learnt about the communication strategy and the commissioning process, and the benefits from the projects. Methods We adopted a wide range of quantitative and qualitative methods. They included: documentary analysis, interviews with key actors, questionnaires to the funded lead researchers, questionnaires to potential users, and desk analysis. Results Quantitative assessment of outputs and dissemination revealed that the IMP funded useful research projects, some of which had considerable impact against the various categories in the HERG payback model, such as publications, further research, research training, impact on health policy, and clinical practice. Qualitative findings from interviews with advisory and commissioning group members indicated that when the IMP was established, implementation research was a relatively unexplored field. This was reflected in the understanding brought to their roles by members of the advisory and commissioning groups, in the way priorities for research were chosen and developed, and in how the research projects were commissioned. The ideological and methodological debates associated with these decisions have continued among those working in this field. The need for an effective communication strategy for the programme as a whole was particularly important. However, such a strategy was never developed, making it difficult to establish the general influence of the IMP as a programme. Conclusion Our findings about the impact of the work funded, and the difficulties faced by those developing the IMP, have implications for the development of strategic programmes of research in general, as well as for the development of more effective research in this field.

During the last decade, Southeast Asian countries have been very successful in reducing the burden of malaria. However, malaria remains endemic in these countries, especially in remote and forested areas. The Leucosphyrus group of the genus Anopheles harbors the most important malaria vectors in forested areas of Southeast Asia. In Vietnam, previous molecular studies have resulted in the identification of only Anopheles dirus sensu stricto (previously known as An. dirus species A) among the Leucosphyrus group members. However, Vietnamese entomologists have recognized that mosquitoes belonging to the Leucosphyrus group in northern Vietnam exhibit morphological characteristics similar to those of Anopheles takasagoensis, which has been reported only from Taiwan. Here, we aimed to confirm the genetic and morphological identities of the members of the Leucosphyrus group in Vietnam. In the molecular phylogenetic trees reconstructed using partial COI and ND6 mitochondrial gene sequences, samples collected from southern and central Vietnam clustered together with GenBank sequences of An. dirus that were obtained from Thailand. However, samples from northern Vietnam formed a distinct clade separated from both An. dirus and An. takasagoensis by other valid species. The results suggest the existence of a cryptic species in northern Vietnam that is morphologically similar to, but phylogenetically distant from both An. dirus and An. takasagoensis. We have tentatively designated this possible cryptic species as Anopheles aff. takasagoensis for convenience, until a valid name is assigned. However, it is difficult to distinguish the species solely on the basis of morphological characteristics. Further studies on such as karyotypes and polytene chromosome banding patterns are necessary to confirm whether An. aff. takasagoensis is a valid species. Moreover, studies on (1) the geographic distribution, which is potentially spreading along the Vietnam, China, Laos, and Myanmar borders; (2) morphological and ecological characteristics; and (3) vectorial capacity of this newly identified cryptic species of An. dirus, which is one of the most important malaria vectors in the mainland of Southeast Asia, are necessary for planning efficient malaria vector control programs in this region.

Is parochial altruism an attribute of individual behavior? This is the question we address with an experiment. We examine whether the individual pro-sociality that is revealed in the public goods and trust games when interacting with fellow group members helps predict individual parochialism, as measured by the in-group bias (i.e., the difference in these games in pro-sociality when interacting with own group members as compared with members of another group). We find that it is not. An examination of the Big-5 personality predictors of each behavior reinforces this result: they are different. In short, knowing how pro-social individuals are with respect to fellow group members does not help predict their parochialism. PMID:26347703

Health care trainees demonstrate implicit (automatic, unconscious) and explicit (conscious) bias against people from stigmatised and marginalised social groups, which can negatively influence communication and decision making. Medical schools are well positioned to intervene and reduce bias in new physicians. This study was designed to assess medical school factors that influence change in implicit and explicit bias against individuals from one stigmatised group: people with obesity. This was a prospective cohort study of medical students enrolled at 49 US medical schools randomly selected from all US medical schools within the strata of public and private schools and region. Participants were 1795 medical students surveyed at the beginning of their first year and end of their fourth year. Web-based surveys included measures of weight bias, and medical school experiences and climate. Bias change was compared with changes in bias in the general public over the same period. Linear mixed models were used to assess the impact of curriculum, contact with people with obesity, and faculty role modelling on weight bias change. Increased implicit and explicit biases were associated with less positive contact with patients with obesity and more exposure to faculty role modelling of discriminatory behaviour or negative comments about patients with obesity. Increased implicit bias was associated with training in how to deal with difficult patients. On average, implicit weight bias decreased and explicit bias increased during medical school, over a period of time in which implicit weight bias in the general public increased and explicit bias remained stable. Medical schools may reduce students' weight biases by increasing positive contact between students and patients with obesity, eliminating unprofessional role modelling by faculty members and residents, and altering curricula focused on treating difficult patients. © 2015 John Wiley & Sons Ltd.

Doctors often find dialogues about death difficult. In Norway, 45% of deaths take place in nursing homes. Newly qualified medical doctors serve as house officers in nursing homes during internship. Little is known about how nursing homes can become useful sites for learning about end-of-life care. The aim of this study was to explore newly qualified doctors' learning experiences with end-of-life care in nursing homes, especially focusing on dialogues about death. House officers in nursing homes (n = 16) participated in three focus group interviews. Interviews were audiotaped and transcribed verbatim. Data were analysed with systematic text condensation. Lave & Wenger's theory about situated learning was used to support interpretations, focusing on how the newly qualified doctors gained knowledge of end-of-life care through participation in the nursing home's community of practice. Newly qualified doctors explained how nursing home staff's attitudes taught them how calmness and acceptance could be more appropriate than heroic action when death was imminent. Shifting focus from disease treatment to symptom relief was demanding, yet participants comprehended situations where death could even be welcomed. Through challenging dialogues dealing with family members' hope and trust, they learnt how to adjust words and decisions according to family and patient's life story. Interdisciplinary role models helped them balance uncertainty and competence in the intermediate position of being in charge while also needing surveillance. There is a considerable potential for training doctors in EOL care in nursing homes, which can be developed and integrated in medical education. This practice based learning arena offers newly qualified doctors close interaction with patients, relatives and nurses, teaching them to perform difficult dialogues, individualize medical decisions and balance their professional role in an interdisciplinary setting.

Analysing researchers’ outreach efforts and the association with publication metrics: A case study of Kudos

With the growth of scholarly collaboration networks and social communication platforms, members of the scholarly community are experimenting with their approach to disseminating research outputs, in an effort to increase their audience and outreach. However, from a researcher’s point of view, it is difficult to determine whether efforts to make work more visible are worthwhile (in terms of the association with publication metrics) and within that, difficult to assess which platform or network is most effective for sharing work and connecting to a wider audience. We undertook a case study of Kudos (https://www.growkudos.com), a web-based service that claims to help researchers increase the outreach of their publications, to examine the most effective tools for sharing publications online, and to investigate which actions are associated with improved metrics. We extracted a dataset from Kudos of 830,565 unique publications claimed by authors, for which 20,775 had actions taken to explain or share via Kudos, and for 4,867 of these full text download data from publishers was available. Findings show that researchers are most likely to share their work on Facebook, but links shared on Twitter are more likely to be clicked on. A Mann-Whitney U test revealed that a treatment group (publications having actions in Kudos) had a significantly higher median average of 149 full text downloads (23.1% more) per publication as compared to a control group (having no actions in Kudos) with a median average of 121 full text downloads per publication. These findings suggest that performing actions on publications, such as sharing, explaining, or enriching, could help to increase the number of full text downloads of a publication. PMID:28817627

2009-10-01

During June 2-8, 2009, an outbreak of influenza A pandemic (H1N1) 2009 occurred among 31 members of a tour group in China. To identify the mode of transmission and risk factors, we conducted a retrospective cohort investigation. The index case-patient was a female tourist from the United States. Secondary cases developed in 9 (30%) tour group members who had talked with the index case-patient and in 1 airline passenger (not a tour group member) who had sat within 2 rows of her. None of the 14 tour group members who had not talked with the index case-patient became ill. This outbreak was apparently caused by droplet transmission during coughing or talking. That airborne transmission was not a factor is supported by lack of secondary cases among fellow bus and air travelers. Our findings highlight the need to prevent transmission by droplets and fomites during a pandemic.

2005-07-01

Two studies compared leader-member exchange (LMX) theory and the social identity theory of leadership. Study 1 surveyed 439 employees of organizations in Wales, measuring work group salience, leader-member relations, and perceived leadership effectiveness. Study 2 surveyed 128 members of organizations in India, measuring identification not salience and also individualism/collectivism. Both studies provided good support for social identity predictions. Depersonalized leader-member relations were associated with greater leadership effectiveness among high-than low-salient groups (Study 1) and among high than low identifiers (Study 2). Personalized leadership effectiveness was less affected by salience (Study 1) and unaffected by identification (Study 2). Low-salience groups preferred personalized leadership more than did high-salience groups (Study 1). Low identifiers showed no preference but high identifiers preferred depersonalized leadership (Study 2). In Study 2, collectivists did not prefer depersonalized as opposed to personalized leadership, whereas individualists did, probably because collectivists focus more on the relational self.

Close relationships and the management of chronic illness: Associations and interventions.

PubMed

Martire, Lynn M; Helgeson, Vicki S

2017-09-01

Self-management of a chronic illness involves not only monitoring symptoms, adhering to medication regimens, and keeping medical appointments but also making and maintaining difficult lifestyle changes. This article highlights correlational and intervention research suggesting family members are influential in children's and adults' illness management. The argument is made that a dyadic approach to chronic illness management that targets the influence of close relationships may yield more sustainable effects on patient behavior than has been achieved in the past. In particular, dyadic approaches aimed at helping patients and family members to find ways to collaborate in goal setting for these behaviors is recommended. Such dyadic interventions may also benefit family members who are ill or are at risk because of poor health behaviors. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Discriminating military and civilian traumatic brain injuries.

PubMed

Reid, Matthew W; Velez, Carmen S

2015-05-01

Traumatic brain injury (TBI) occurs at higher rates among service members than civilians. Explosions from improvised explosive devices and mines are the leading cause of TBI in the military. As such, TBI is frequently accompanied by other injuries, which makes its diagnosis and treatment difficult. In addition to postconcussion symptoms, those who sustain a TBI commonly report chronic pain and posttraumatic stress symptoms. This combination of symptoms is so typical they have been referred to as the "polytrauma clinical triad" among injured service members. We explore whether these symptoms discriminate civilian occurrences of TBI from those of service members, as well as the possibility that repeated blast exposure contributes to the development of chronic traumatic encephalopathy (CTE).

The redshift-space neighborhoods of 36 loose groups. 2: Analysis

1995-01-01

We explore the kinematics of 36 rich RGH89 groups identified from the first two complete slices of the CfA redshift survey. These groups have more than five members identified by a friends-of-friends algorithm at a number density contrast delta rho/rho greater than or equal to 80. To examine the stability of the determination of the velocity dispersion for these systems, we compare results for the original 232 members with results for a larger redshift sample, including 334 fainter members in the redshift neighborhoods. On average, we double the number of group members in each system. The observed distribution of velocity dispersions is stable. In fact, the velocity dispersion based on the original members identified in the CfA redshift survey is a reliable predictor of the value for the enlarged sample in an individual group. The velocity dispersion is thus a stable physical parameter for discrimination among systems galaxies. A larger sample of groups, particularly one selected from a distance limited catalog, should provide an interesting constraint on models for the formation of large-scale structure. We take H(sub 0) = km/s/Mpc.

Communities of Practice Transition Online - Lessons learned from NASA's EPO Online Workspace

Davey, B.

2012-12-01

The Earth Forum Education and Public Outreach (EP/O) community has long interacted to better their practice as a community as well as individually. Working together to share knowledge and grow, they function as a community of practice. In 2009, NASA designed and implemented an online workspace in hopes of promoting the communities continued interactions. This study examines the role of an online workspace component of a community in the work of a community of practice. Much has been studied revealing the importance of communities of practice to organizations, project success, and knowledge management and some of these same successes hold true for virtual communities of practice. Study participants were 75 Education and Public Outreach community members of NASA's Science Mission Directorate Earth Forum. In this mixed methods study, online workspace metrics were used to track participation and a survey completed by 21 members was used to quantify participation. For a more detailed analysis, 15 community members (five highly active users, five average users, and five infrequent users) selected based on survey responses, were interviewed. Finally, survey data was gathered from seven online facilitators to understand their role in the community. Data collected from these 21 community members and five facilitating members suggest that highly active users (logging into the workspace daily), were more likely to have transformative experiences, co-create knowledge, feel ownership of community knowledge, have extended opportunities for community exchange, and find new forms of evaluation. Average users shared some similar characteristics with both the highly active members and infrequent users, representing a group in transition as they become more engaged and active in the online workspace. Inactive users viewed the workspace as having little value, being difficult to navigate, being mainly for gaining basic information about events and community news, and as another demand on their time. Results show the online workspace component of the Earth Science Education and Outreach Forum is playing an important and emerging role for this community by supporting knowledge building and knowledge sharing, and growing in value for those that utilizing it more frequently. The evidence suggests that with increased participation or "usage" comes increased value to the participant and the organization. This research illustrates the possible change in mindset held by participating community members when it comes to the nature of co-location. Additionally, it may be of particular importance in exploring changes in the community members' feelings of connection and belonging.

Utilization of and Barriers to HIV and MCH Services among Community ART Group Members and Their Families in Tete, Mozambique

2013-01-01

Mozambique continues to face many challenges in HIV and maternal and child health care (MCH). Community-based antiretroviral treatment groups (CAG) enhance retention to care among members, but whether such benefits extend to their families and to MCH remains unclear. In 2011 we studied utilization of HIV and MCH services among CAG members and their family aggregates in Changara, Mozambique, through a mixed-method assessment. We systematically revised all patient-held health cards from CAG members and their non-CAG family aggregate members and conducted semistructured group discussions on MCH topics. Quantitative data were analysed in EPI-Info. Qualitative data were manually thematically analysed. Information was retrieved from 1,624 persons, of which 420 were CAG members (26%). Good compliance with HIV treatment among CAG members was shared with non-CAG HIV-positive family members on treatment, but many family aggregate members remained without testing, and, when HIV positive, without HIV treatment. No positive effects from the CAG model were found for MCH service utilization. Barriers for utilization mentioned centred on insufficient knowledge, limited community-health facility collaboration, and structural health system limitations. CAG members were open to include MCH in their groups, offering the possibility to extend patient involvement to other health needs. We recommend that lessons learnt from HIV-based activism, patient involvement, and community participation are applied to broader SRH services, including MCH care. PMID:23956849

Empirical study on social groups in pedestrian evacuation dynamics

NASA Astrophysics Data System (ADS)

von Krüchten, Cornelia; Schadschneider, Andreas

2017-06-01

Pedestrian crowds often include social groups, i.e. pedestrians that walk together because of social relationships. They show characteristic configurations and influence the dynamics of the entire crowd. In order to investigate the impact of social groups on evacuations we performed an empirical study with pupils. Several evacuation runs with groups of different sizes and different interactions were performed. New group parameters are introduced which allow to describe the dynamics of the groups and the configuration of the group members quantitatively. The analysis shows a possible decrease of evacuation times for large groups due to self-ordering effects. Social groups can be approximated as ellipses that orientate along their direction of motion. Furthermore, explicitly cooperative behaviour among group members leads to a stronger aggregation of group members and an intermittent way of evacuation.

Staff of long-term care facilities and family members have a common responsibility to ensure the best course of treatment and everyday care for residents who often cannot speak for themselves. Understanding the difference between instrumental and preservative care, and who the proper agent is to provide care in each category will not only improve staff/family interactions, but residential care in general. The Resident Enrichment and Activity Program improves the family/staff relationship obliquely by involving family in social activities; the Family Involvement in Care program, and the Patterns in Caregiving program directly target the relationship and involve the facility's administration to effect policy change.

Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF.

The company they keep: drinking group attitudes and male bar aggression.

PubMed

Dumas, Tara M; Graham, Kathryn; Wells, Samantha

2015-05-01

The purpose of this study was to assess (a) similarities in self-reported bar-aggression-related attitudes and behaviors among members of young male groups recruited on their way to bars and (b) group-level variables associated with individual members' self-reported likelihood of perpetrating physical bar aggression in the past year, controlling for individual attitudes. Young, male, natural drinking groups recruited on their way to a bar district Thursday, Friday, and Saturday nights (n = 167, 53 groups) completed an online survey that measured whether they had perpetrated physical aggression at a bar in the past year and constructs associated with bar aggression, including attitudes toward male bar aggression and frequency of heavy episodic drinking in the past year. Intraclass correlations and chi-square tests demonstrated significant within-group similarity on bar-aggression-related attitudes and behaviors (ps < .01). Hierarchical linear modeling revealed that group attitudes toward bar aggression were significantly associated with individuals' likelihood of perpetrating physical bar aggression, controlling for individual attitudes (p < .01); however, the link between group heavy episodic drinking and self-reported bar aggression was nonsignificant in the full model. This study suggests that the most important group influence on young men's bar aggression is the attitudes of other group members. These attitudes were associated with group members' likelihood of engaging in bar aggression over and above individuals' own attitudes. A better understanding of how group attitudes and behavior affect the behavior of individual group members is needed to inform aggression-prevention programming.

2014-01-01

To examine the use of online social networking for cardiovascular care using Facebook. All posts and comments in a Facebook group between June 2011 and May 2012 were reviewed, and a survey was conducted. A total of 298 members participated. Of the 277 wall posts, 26.7% were question posts requesting rapid replies, and 50.5% were interesting cases shared with other members. The median response time for the question posts was 16 min (IQR 8-47), which tended to decrease as more members joined the group. Many members (37.4%) accessed the group more than once a day, and more than half (64%) monitored the group posts in real time with automatic notifications of new posts. Most members expressed confidence in the content posted. Facebook enables online social networking between physicians in near-real time and appears to be a useful tool for physicians to share clinical experience and request assistance in decision-making.

Two studies were conducted. Study 1 examined how affiliation with a social group that has clear-cut, rigid norms and values affects the personal and social self-concept. Participants were members of a (self-defining) Turkish nationalist organisation (N=66) and a control group of Turkish university students (N=58). Paradoxically, high levels of national identification were associated with stronger personal identity. Study 2 used the same participant population (N=177) and manipulated self-focused attention by means of a mirror. Self-aware members reported the highest levels of identification with the nationalist organisation. Results suggest that members of this groups show no signs of 'vanishing individuality': although boundaries between personal and social identities are blurred, extremist group members retain a distinct and strengthened sense of personal identity. This raises some interesting questions for the concept of personal identity and how it can be informed by the content of one's social identity.

The Australian Longitudinal Study on Women's Health: Using Focus Groups to Inform Recruitment

PubMed Central

2016-01-01

Background Recruitment and retention of participants to large-scale, longitudinal studies can be a challenge, particularly when trying to target young women. Qualitative inquiries with members of the target population can prove valuable in assisting with the development of effective recruiting techniques. Researchers in the current study made use of focus group methodology to identify how to encourage young women aged 18-23 to participate in a national cohort online survey. Objective Our objectives were to gain insight into how to encourage young women to participate in a large-scale, longitudinal health survey, as well as to evaluate the survey instrument and mode of administration. Methods The Australian Longitudinal Study on Women’s Health used focus group methodology to learn how to encourage young women to participate in a large-scale, longitudinal Web-based health survey and to evaluate the survey instrument and mode of administration. Nineteen groups, involving 75 women aged 18-23 years, were held in remote, regional, and urban areas of New South Wales and Queensland. Results Focus groups were held in 2 stages, with discussions lasting from 19 minutes to over 1 hour. The focus groups allowed concord to be reached regarding survey promotion using social media, why personal information was needed, strategies to ensure confidentiality, how best to ask sensitive questions, and survey design for ease of completion. Recruitment into the focus groups proved difficult: the groups varied in size between 1 and 8 participants, with the majority conducted with 2 participants. Conclusions Intense recruitment efforts and variation in final focus group numbers highlights the “hard to reach” character of young women. However, the benefits of conducting focus group discussions as a preparatory stage to the recruitment of a large cohort for a longitudinal Web-based health survey were upheld. PMID:26902160

1) To explore family members' lived experiences of driving disruption at early and later stages of the recovery continuum following acquired brain injury (ABI). 2) To describe health-related quality of life of family members of individuals with ABI who are experiencing driving disruption. Mixed methods phenomenological research approach. Semi-structured interviews and health-related quality of life questionnaires were conducted with 15 family members of individuals with ABI (early group: 1-12 months post-injury, n = 6; later group: >1 year post-injury, n = 9). Two main themes were identified: Different for everyone: how driving disruption affects families, and Making it harder: context of driving disruption. The challenges of driving disruption were reported more frequently and with a more intense focus by family members who were caring for their relative for more than 1 year post-injury. This group also reported higher caregiver strain and poorer health-related quality of life. Reduced satisfaction with life, poor mental health and affected family functioning were reported by both groups. Driving disruption impacts on family members and has long-lasting consequences. It is important for clinicians to work with family members to manage these challenges even years after ABI and consider individual contextual factors.

Bayesian assessment of moving group membership: importance of models and prior knowledge

Young nearby moving groups are important and useful in many fields of astronomy such as studying exoplanets, low-mass stars, and the stellar evolution of the early planetary systems over tens of millions of years, which has led to intensive searches for their members. Identification of members depends on the used models sensitively; therefore, careful examination of the models is required. In this study, we investigate the effects of the models used in moving group membership calculations based on a Bayesian framework (e.g. BANYAN II) focusing on the beta-Pictoris moving group (BPMG). Three improvements for building models are suggested: (1) updating a list of accepted members by re-assessing memberships in terms of position, motion, and age, (2) investigating member distribution functions in XYZ, and (3) exploring field star distribution functions in XYZ and UVW. The effect of each change is investigated, and we suggest using all of these improvements simultaneously in future membership probability calculations. Using this improved MG membership calculation and the careful examination of the age, 57 bona fide members of BPMG are confirmed including 12 new members. We additionally suggest 17 highly probable members.

Competition in human groups-Impact on group cohesion, perceived stress and outcome satisfaction.

PubMed

Boos, Margarete; Franiel, Xaver; Belz, Michael

2015-11-01

This study on competition in human groups was performed within the context of the competitive outcome interdependence concept: the degree to which personal outcomes among group members are affected by the consequences of task performance of others, e.g. when one group member gains a high reward for a task, this lowers the available reward for other group members. Our computer-based multi-participant game empirically assessed how competitive versus neutral conditions influenced the reward-maximising behaviour of 200 undergraduate students functioning in ten-person groups - each playing two games (1 neutral and 1 competitive), their perceived pay satisfaction as well as perceived stress levels and sense of calmness within the games' task to search for coins. Participants were represented by black dots moving on a virtual playground. Results showed that competition led to reward-maximising but fellow group member disadvantaging behaviour, and all participants experienced lower pay satisfaction, higher stress levels and less calmness. We conclude that short-term behavioural consequences of positive individual competitive behaviour were gained at the above-mentioned potential long-term negative costs for all group members. This implies group paradigms aimed at sustainability should avoid introducing competitive factors that at best result in short-lived gains and at worst cause widespread dissatisfaction, stress and a pervasive lack of calmness.

Reticulate evolution in North American black-fruited hawthorns (Crataegus section Douglasia; Rosaceae): evidence from nuclear ITS2 and plastid sequences.

PubMed

Zarrei, M; Stefanović, S; Dickinson, T A

2014-08-01

The taxonomic complexity of Crataegus (hawthorn; Rosaceae, Maleae), especially in North America, has been attributed by some to hybridization in combination with gametophytic apomixis and polyploidization, whereas others have considered the roles of hybridization and apomixis to be minimal. Study of the chemical composition and therapeutic value of hawthorn extracts requires reproducible differentiation of entities that may be difficult to distinguish by morphology alone. This study sought to address this by using the nuclear ribosomal spacer region ITS2 as a supplementary DNA barcode; however, a lack of success prompted an investigation to discover why this locus gave unsatisfactory results. ITS2 was extensively cloned so as to document inter- and intraindividual variation in this locus, using hawthorns of western North America where the genus Crataegus is represented by only two widely divergent groups, the red-fruited section Coccineae and the black-fruited section Douglasia. Additional sequence data from selected loci on the plastid genome were obtained to enhance further the interpretation of the ITS2 results. In the ITS2 gene tree, ribotypes from western North American hawthorns are found in two clades. Ribotypes from diploid members of section Douglasia occur in one clade (with representatives of the east-Asian section Sanguineae). The other clade comprises those from diploid and polyploid members of section Coccineae. Both clades contribute ribotypes to polyploid Douglasia. Data from four plastid-derived intergenic spacers demonstrate the maternal parentage of these allopolyploids. Repeated hybridization between species of section Douglasia and western North American members of section Coccineae involving the fertilization of unreduced female gametes explains the observed distribution of ribotypes and accounts for the phenetic intermediacy of many members of section Douglasia. © The Author 2014.

A Method of Strengthening Composite/Metal Joints

NASA Technical Reports Server (NTRS)

Polis, Daniel L.

2011-01-01

The term tape setback method denotes a method of designing and fabricating bonded joints between (1) box beams or other structural members made of laminated composite (matrix/ fiber) materials and (2) metal end fittings used to fasten these structural members to other structural members. The basic idea of the tape setback method is to mask the bonded interface between the metallic end fitting and composite member such that the bond does not extend out to the free edges of the composite member. The purpose served by the tape setback method is to strengthen the joints by decoupling stress concentrations from edge defects, which can cause premature failures. A related prior method that serves a similar purpose, involving the use of tapered adherends at the joints, can be too difficult and costly to be acceptable in some applications. The tape setback method offers an easier, less costly alternative. The structural members to which the method was originally applied were box beams in the form of composite tubes having flat faces with rounded corners. The end fittings were plugs made of a low-thermal- expansion nickel/iron alloy (see figure). In computational-simulation studies of tensile and compressive loading of members without tape setback, stresses were found to be concentrated at the free end edges of the composite tubes, and inspection of members that had been subjected to real tension and compression tests showed that cracks started at the free end edges. As applied to these members, the tape setback method makes them less vulnerable to initiation of failure at edge defects produced during fabrication. In real tension tests of comparable members without and with tape setback, the average mean tensile strength of the members with tape setback was found to be 1.9 times that of the members without tape setback.

Sediment transport processes in the Pearl River Estuary as revealed by grain-size end-member modeling and sediment trend analysis

NASA Astrophysics Data System (ADS)

Li, Tao; Li, Tuan-Jie

2018-04-01

The analysis of grain-size distribution enables us to decipher sediment transport processes and understand the causal relations between dynamic processes and grain-size distributions. In the present study, grain sizes were measured from surface sediments collected in the Pearl River Estuary and its adjacent coastal areas. End-member modeling analysis attempts to unmix the grain sizes into geologically meaningful populations. Six grain-size end-members were identified. Their dominant modes are 0 Φ, 1.5 Φ, 2.75 Φ, 4.5 Φ, 7 Φ, and 8 Φ, corresponding to coarse sand, medium sand, fine sand, very coarse silt, silt, and clay, respectively. The spatial distributions of the six end-members are influenced by sediment transport and depositional processes. The two coarsest end-members (coarse sand and medium sand) may reflect relict sediments deposited during the last glacial period. The fine sand end-member would be difficult to transport under fair weather conditions, and likely indicates storm deposits. The three remaining fine-grained end-members (very coarse silt, silt, and clay) are recognized as suspended particles transported by saltwater intrusion via the flood tidal current, the Guangdong Coastal Current, and riverine outflow. The grain-size trend analysis shows distinct transport patterns for the three fine-grained end-members. The landward transport of the very coarse silt end-member occurs in the eastern part of the estuary, the seaward transport of the silt end-member occurs in the western part, and the east-west transport of the clay end-member occurs in the coastal areas. The results show that grain-size end-member modeling analysis in combination with sediment trend analysis help to better understand sediment transport patterns and the associated transport mechanisms.

Group heterogeneity increases the risks of large group size: a longitudinal study of productivity in research groups.

PubMed

Cummings, Jonathon N; Kiesler, Sara; Bosagh Zadeh, Reza; Balakrishnan, Aruna D

2013-06-01

Heterogeneous groups are valuable, but differences among members can weaken group identification. Weak group identification may be especially problematic in larger groups, which, in contrast with smaller groups, require more attention to motivating members and coordinating their tasks. We hypothesized that as groups increase in size, productivity would decrease with greater heterogeneity. We studied the longitudinal productivity of 549 research groups varying in disciplinary heterogeneity, institutional heterogeneity, and size. We examined their publication and citation productivity before their projects started and 5 to 9 years later. Larger groups were more productive than smaller groups, but their marginal productivity declined as their heterogeneity increased, either because their members belonged to more disciplines or to more institutions. These results provide evidence that group heterogeneity moderates the effects of group size, and they suggest that desirable diversity in groups may be better leveraged in smaller, more cohesive units.

A Large Ordinary Chondrite Shower in the Dominion Range

The US Antarctic Meteorite Program has visited the Dominion Range in the Transantarctic Mountains during several different seasons, including the 1985, 2003, 2008, 2010, and 2014 seasons. Total recovered meteorites from this region is over 2000. The 2008 and 2010 seasons have been fully classified and, respectively) revealing the presence of a large meteorite shower that comprises approximately 60% of all samples recovered in those two seasons. The oil immersion classification suggests that this shower is LL chondrite material, whereas published magnetic susceptibility (MS; log chi) measurements yield L chondrite values. However, usually random sampling of a large collection like this would uncover EOC material for which we have prepared thin sections. In this case, no LL chondrite materials have been found in thin section, suggesting that the shower might instead be an L chondrite. L and LL chondrites are notoriously difficult to distinguish using oil immersion techniques. To better characterize this large group of samples, we have decided to examine some of the large members of this group, using EMPA analysis of the olivines to verify the classifications. With a compositional link between this subset of samples, and the MS measurements, we can more confidently classify the samples making up this pairing group. Subsequently, more accurate and meaningful comparisons may be drawn between this pairing group and some other Antarctic pairing groups such as from the Queen Alexandra Range (QUE), and Lewis Cliffs Ice Tongue (LEW). electron microprobe analysis

Graves' disease and Hashimoto's thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves' disease from Hashimoto's thyroiditis. This study included 149 patients divided into three groups, patients with Graves' disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto's thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves' was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto's group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves' group with 100% and 17.6% specificity and sensitivity, respectively. Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves' disease or Hashimoto's thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed.

There is a paucity of literature on the personal experiences of burn support group members, the members' perceived benefits of group participation, and the meaning the survivors make of the support they receive. In order to provide effective psychosocial rehabilitation services and to meet the needs of burn survivors, it is important to understand the influence a support group has on its members as well as the personal experiences of those individuals who attend these groups. The purpose of this study was to explore the experiences of burn survivors in a burn survivor support group. Six self-identified burn survivors were interviewed by using a guided in-depth interview technique to explore their experiences in the support group. Key informant interviews and group observations served to triangulate the findings from the individual interviews. The experiences of the group members coalesced around four main themes: acceptance of self, perspective change, value of community, and reciprocity. The findings demonstrated the overall perceived positive impact the support group had on psychosocial recovery. For these members, the group aided the process of adjustment through the encouragement of adaptive coping strategies and the facilitation of community and relationships. Their experiences mirrored much of the literature on psychological growth from adversity. Burn survivors reported unique opportunities that allowed them to integrate their injury into their identity within an encouraging and safe environment. Using these accounts, the authors generated clinical suggestions that may encourage similar growth in other support group settings.

Phylogenomics and comparative genomic studies delineate six main clades within the family Enterobacteriaceae and support the reclassification of several polyphyletic members of the family.

The family Enterobacteriaceae harbors many important pathogens, however it has proven difficult to reliably distinguish different members of this family or discern their interrelationships. To understand the interrelationships among the Enterobacteriaceae species, we have constructed two comprehensive phylogenetic trees for 78 genome-sequenced Enterobacteriaceae species based on 2487 core genome proteins, and another set of 118 conserved proteins. The genome sequences of Enterobacteriaceae species were also analyzed for genetic relatedness based on average amino acid identity and 16S rRNA sequence similarity. In parallel, comparative genomic studies on protein sequences from the Enterobacteriaceae have identified 88 molecular markers in the form of conserved signature indels (CSIs) that are uniquely shared by specific members of the family. All of these multiple lines of investigations provide consistent evidence that most of the species/genera within the family can be assigned to 6 different subfamily level clades which are designated as the "Escherichia clade", "Klebsiella clade", "Enterobacter clade", "Kosakonia clade", "Cronobacter clade" and "Cedecea clade". The members of the six described clades, in addition to their distinct branching in phylogenetic trees, can now be reliably demarcated in molecular terms on the basis of multiple identified CSIs that are exclusively shared by the group members. Several additional CSIs identified in this work that are either specific for individual genera (viz. Kosakonia, Kluyvera and Escherichia-Shigella), or are present at various taxonomic depths, offer information regarding the interrelationships among the different clades. The described molecular markers provide novel means for diagnostic as well as genetic and biochemical studies on the Enterobacteriaceae species and for resolving the polyphyly of its several genera viz. Escherichia, Enterobacter and Kluyvera. On the bases of our results, we are proposing the reclassification of Escherichia vulneris and Enterobacter massiliensis into two novel genera viz. Pseudescherichia gen. nov. and Metakosakonia gen. nov., respectively. Additionally, our results also support the transfer of "Enterobacter lignolyticus" and "Kluyvera intestini" to the genera Pluralibacter and Metakosakonia, respectively. Copyright © 2017 Elsevier B.V.

PubMed

Begovac, Branka; Begovac, Ivan

2012-09-01

This article presents, in the form of a clinical illustration, a therapeutic group of bereaved mothers with special reference to their dreams about their deceased children. The article presents descriptions of the emotions of these mothers and countertransference feelings, a topic that, to our knowledge, has not been frequently studied. The group was small, analytically oriented, slow-open, comprised of women bereaved by the death of a child, and conducted by a female therapist. Over more than three years, the group included 20 members in total. This article describes a number of dreams recorded during a period when the group included seven members. Dreams helped the group members access their emotional pain, helplessness, yearning for a relationship with the deceased, guilt, and feelings of survival guilt. The transference-countertransference relationships were characterized by holding. Countertransference feelings of helplessness predominated. The therapist and the group as a whole contained various emotions, allowing the group members to return to the normal mourning processes from the parallel encouragement of group development and interpersonal relationships.

Pickering, H; Kajura, E; Katongole, G; Whitworth, J

1996-10-01

This study is based on interviews conducted among 8 women's income-generating groups and 12 individual women entrepreneurs in 15 villages in Masaka district, Uganda. The Baganda are the main tribe in the study villages. The study evaluates the economic achievement, objectives, and social characteristics of the groups. Groups ranged in size from 9-20 members. All had functioned for 3-5 years. A regular membership fee was paid through the sale of agricultural produce. Groups met at least every 2 weeks. This study revealed that the individual goals were to increase individual wealth, while the stated group goals were to invest in the community. Members considered the groups as useful in providing an easy way to raise capital. Most members considered financial status as a criterion for group membership. Elderly women tended to join social and handicraft groups. The women's group members tended to be friends before the establishment of the group and tended to be currently married to men residing in the area. Of the 12 women entrepreneurs, only 5 were currently married. All 12 women entrepreneurs had considerable initiative. The 12 women and the women's group members derived income from two or more sources: agricultural projects, animal husbandry, craft production, alcohol production and sale, or other activities. Study findings indicate that decisions were often delayed or avoided in order to preserve social cohesion. In a market-oriented enterprise, quick response time is needed and the bureaucratic dynamics would hinder some agricultural ventures. The poorest women experienced barriers to group membership. Women entrepreneurs were more successful than group women.

SMS reminders to improve the tuberculosis cure rate in developing countries (TB-SMS Cameroon): a protocol of a randomised control study

PubMed Central

2014-01-01

Background Tuberculosis is a public health problem in Cameroon, just like in many other countries in the world. The National Tuberculosis Control Programme (PNLT) put in place by the state, aims to fight tuberculosis through the implementation of international directives (Directly Observed Treatment Short, DOTS). Despite the deployment of this strategy across the world, its implementation is difficult in the context of low-resource countries. Some expected results are not achieved. In Cameroon, the cure rate for patients with sputum positive pulmonary tuberculosis (TPM+) after 6 months is only about 65%, 20% below the target. This is mainly due to poor patient adherence to treatment. By relying on the potential of mobile Health, the objective of this study is to evaluate the effect of SMS reminders on the cure rate of TPM + patients, measured using 6-month bacilloscopy. Methods/design This is a blinded, randomised controlled multicentre study carried out in Cameroon. The research hypothesis is that sending daily SMS messages to remind patients to take their prescribed tuberculosis medication, together with the standard DOTS strategy, will increase the cure rate from 65% (control group: DOTS, no SMS intervention) to 85% (intervention group: DOTS, with SMS intervention) in a group of new TPM + patients. In accordance with each treatment centre, the participants will be randomly allocated into the two groups using a computer program: the intervention group and the control group. A member of the research team will send daily SMS messages. Study data will be collected by health professionals involved in the care of patients. Data analysis will be done by the intention-to-treat method. Discussion The achieving of expected outcomes by the PNLT through implementation of DOTS requires several challenges. Although it has been demonstrated that the DOTS strategy is effective in the fight against tuberculosis, its application remains difficult in developing countries. This study explores the potential of mHealth to support DOTS strategy. It will gather new evidence on the effectiveness of mHealth-based interventions and SMS reminders in the improvement of treatment adherence and the cure rate of tuberculosis patients, especially in a low-resource country such as Cameroon.

The aim of this study was to determine the effects of the psychoeducation received by the family members of the patients with first-episode schizophrenia on the expressed emotion (EE) and the family functioning of the family members. This study has a quasi-experimental design with a control group. The sample of the study was 60 family members (30 experimental -30 control) of the patients with first-episode schizophrenia. The experimental group received 9 weeks of psychoeducation as a group. EE and family functioning were assessed at the beginning and at the end of the psychoeducation program. EE criticism/hostility and over involvement-protecting-intervention levels of the family members have decreased at the end of the psychoeducation (p < 0.05). Family functioning has changed too at the end of the psychoeducation (p < 0.05), and assessed as more healthy. Consequently, early psychoeducational groups may be effective in decreasing EE level and improving the family functioning for a family member of patient with first-episode schizophrenia.

Facilitating social support: member-leader communication in a breast cancer support group.

PubMed

Beck, Stephenson J; Keyton, Joann

2014-01-01

Early detection and treatment have resulted in more women surviving breast cancer; increased survivorship has also increased the need for breast cancer support groups (BCSG). The ostensible goal of such groups is to provide support for the physical and emotional stressors that cancer survivors face, as well as provide information on coping and treatment options. Although scholars have examined the effects of support groups on their group members, the examination of group facilitator messages has been largely neglected. The goal of this study was to extend theory on group leader behavior, specifically investigating how member-leader messages create social support in support groups. The transcribed conversations of weekly meetings of a BCSG were examined using Interaction Process Analysis to discover how the member-leader facilitated the group's enactment and management of social support. Across the meetings, task talk dominated (primarily statements of orientation or information). Furthermore, analysis of interaction sequences between the support group facilitator and other members revealed 2 broad categories of task-oriented facilitation techniques (changing the focus, clarification) and 1 category of socioemotional facilitation techniques (showing support). Support group facilitators need the ability to facilitate both task and relational aspects of social support. Facilitator behaviors were highlighted as being instrumental to the creation of social support. The results from this study indicate that the ability to change the focus of interaction, to provide and require clarification on complex issues, and to show support through relational messages is needed in facilitator training.

Sport and exercise participation exert a positive effect on numerous aspects of individuals' health. Although sport and exercise leaders have generally been observed to play a key role in shaping group members' behavior, our understanding of their impact on group members' attendance in sport and exercise sessions is limited. To address this, and building on promising findings in other domains, we examined the associations between perceptions of sport and exercise leaders' engagement in social identity leadership, group identification, and attendance. A sample of 583 participants from sports teams (n = 307) and exercise groups (n = 276) completed questionnaires measuring identity leadership, group identification, and attendance. Analyses demonstrated that perceptions of leader engagement in social identity leadership were positively associated with members' group identification, and that this in turn was positively associated with their attendance in either a sports group or an exercise group. Moreover, there was a significant indirect effect for perceptions of leader engagement in identity leadership on group members' attendance through their greater identification with these groups. Findings highlight the importance of considering the impact sport and exercise leaders have on group members' attendance and suggest that leaders who represent, advance, create, and embed a shared sense of identity (ie, a shared sense of "us") among attendees can promote participation in sport and exercise. © 2018 The Authors.

A conflict of interest is defined as "a set of conditions in which professional judgment concerning a primary interest (such as a patient's welfare or the validity of research) tends to be unduly influenced by a secondary interest (such as financial gain)" [Thompson DF. Understanding financial conflicts of interest. N Engl J Med 1993;329(8):573-576]. Because financial conflict of interest (fCOI) can occur at different stages of a study, and because it can be difficult for investigators to detect their own bias, particularly retrospectively, we sought to provide funders, journal editors and other stakeholders with a standardized tool that initiates detailed reporting of different aspects of fCOI when the study begins and continues that reporting throughout the study process to publication. We developed a checklist using a 3-phase process of pre-meeting item generation, a stakeholder meeting and post-meeting consolidation. External experts (n = 18), research team members (n = 12) and research staff members (n = 4) rated or reviewed items for some or all of the 7 major iterations. The resulting Financial Conflicts of Interest Checklist 2010 consists of 4 sections covering administrative, study, personal financial, and authorship information, which are divided into 6 modules and contain a total of 15 items and their related sub-items; it also includes a glossary of terms. The modules are designed to be completed by all investigators at different points over the course of the study, and updated information can be appended to the checklist when it is submitted to stakeholder groups for review. We invite comments and suggestions for improvement at http://www.openmedicine.ca/fcoichecklist and ask stakeholder groups to endorse the use of the checklist.

CAD or MAD? Anger (not disgust) as the predominant response to pathogen-free violations of the divinity code.

The CAD triad hypothesis (Rozin, Lowery, Imada, & Haidt, 1999) stipulates that, cross-culturally, people feel anger for violations of autonomy, contempt for violations of community, and disgust for violations of divinity. Although the disgust-divinity link has received some measure of empirical support, the results have been difficult to interpret in light of several conceptual and design flaws. Taking a revised methodological approach, including use of newly validated (Study 1), pathogen-free violations of the divinity code, we found (Study 2) little evidence of disgust-related phenomenology (nausea, gagging, loss of appetite) or action tendency (desire to move away), but much evidence of anger-linked desire to retaliate, as a major component of individuals' projected response to "pure" (pathogen-free) violations of the divinity code. Study 3 replicated these results using faces in lieu of words as a dependent measure. Concordant findings emerged from an archival study (Study 4) examining the aftermath of a real-life sacred violation-the burning of Korans by U.S. military personnel. Study 5 further corroborated these results using continuous measures based on everyday emotion terms and new variants of the divinity-pure scenarios featuring sacrilegious acts committed by a theologically irreverent member of one's own group rather than an ideologically opposed member of another group. Finally, a supplemental study found the anger-dominant attribution pattern to remain intact when the impious act being judged was the judge's own. Based on these and related results, we posit anger to be the principal emotional response to moral transgressions irrespective of the normative content involved.

Prunus spp. are affected by a large number of viruses, causing significant economic losses through either direct or indirect damage, which results in reduced yield and fruit quality. Among these viruses, members of the genus Ilarvirus (isometric labile ringspot viruses) occupy a significant position due to their distribution worldwide. Although symptoms caused by these types of viruses were reported early in the last century, their molecular characterization was not achieved until the 1990s, much later than for other agronomically relevant viruses. This was mainly due to the characteristic liability of virus particles in tissue extracts. In addition, ilarviruses, together with Alfalfa mosaic virus, are unique among plant viruses in that they require a few molecules of the coat protein in the inoculum in order to be infectious, a phenomenon known as genome activation. Another factor that has made the study of this group of viruses difficult is that infectious clones have been obtained only for the type member of the genus, Tobacco streak virus. Four ilarviruses, Prunus necrotic ringspot virus, Prune dwarf virus, Apple mosaic virus, and American plum line pattern virus, are pathogens of the main cultivated fruit trees. As stated in the 9th Report of the International Committee on Taxonomy of Viruses, virions of this genus are "unpromising subjects for the raising of good antisera." With the advent of molecular approaches for their detection and characterization, it has been possible to get a more precise view of their prevalence and genome organization. This review updates our knowledge on the incidence, genome organization and expression, genetic diversity, modes of transmission, and diagnosis, as well as control of this peculiar group of viruses affecting fruit trees.

Challenging emotional prejudice by changing self-concept: priming independent self-construal reduces racial in-group bias in neural responses to other's pain.

Humans show stronger empathy for in-group compared with out-group members' suffering and help in-group members more than out-group members. Moreover, the in-group bias in empathy and parochial altruism tend to be more salient in collectivistic than individualistic cultures. This work tested the hypothesis that modifying self-construals, which differentiate between collectivistic and individualistic cultural orientations, affects in-group bias in empathy for perceived own-race vs other-race pain. By scanning adults using functional magnetic resonance imaging, we found stronger neural activities in the mid-cingulate, left insula and supplementary motor area (SMA) in response to racial in-group compared with out-group members' pain after participants had been primed with interdependent self-construals. However, the racial in-group bias in neural responses to others' pain in the left SMA, mid-cingulate cortex and insula was significantly reduced by priming independent self-construals. Our findings suggest that shifting an individual's self-construal leads to changes of his/her racial in-group bias in neural responses to others' suffering. © The Author (2015).

Survival lotteries reconsidered.

PubMed

Øverland, Gerhard

2007-09-01

In 1975 John Harris envisaged a survival lottery to redistribute organs from one to a greater number in order to reduce number of deaths as a consequence of organ failure. In this paper I reach a conclusion about when running a survival lottery is permissible by looking at the reason prospective participants have for allowing the procedure from a contractual perspective. I identify three versions of the survival lottery. In a National Lottery, everyone within a jurisdiction is a candidate for being a donor for everyone else, disregarding all differences between individuals' eventual possibility of needing an organ. In a Group Specific Lottery, it is a question of running a lottery among members of a specific group who share the same probability of getting organ failure. In a Local Lottery one randomises among individuals who are already in need of a new organ but who happen to be compatible and in need of different organs. While the first is vulnerable to considerations of fairness, it is difficult to perceive a feasible way to implement the second option that does not come with a host of unwelcome consequences. I argue, however, that it is permissible to run Local Lotteries.

Activation of remote meta-C-H bonds assisted by an end-on template.

Functionalization of unactivated carbon-hydrogen (C-H) single bonds is an efficient strategy for rapid generation of complex molecules from simpler ones. However, it is difficult to achieve selectivity when multiple inequivalent C-H bonds are present in the target molecule. The usual approach is to use σ-chelating directing groups, which lead to ortho-selectivity through the formation of a conformationally rigid six- or seven-membered cyclic pre-transition state. Despite the broad utility of this approach, proximity-driven reactivity prevents the activation of remote C-H bonds. Here we report a class of easily removable nitrile-containing templates that direct the activation of distal meta-C-H bonds (more than ten bonds away) of a tethered arene. We attribute this new mode of C-H activation to a weak 'end-on' interaction between the linear nitrile group and the metal centre. The 'end-on' coordination geometry relieves the strain of the cyclophane-like pre-transition state of the meta-C-H activation event. In addition, this template overrides the intrinsic electronic and steric biases as well as ortho-directing effects with two broadly useful classes of arene substrates (toluene derivatives and hydrocinnamic acids).

Latino immigrant families with children with disabilities experience multiple sources of oppression during their settlement process in the United States. Unfair social structures and dominant cultural values and norms and the way they influence the immigrants' personal life stories generate a cycle of oppression very difficult to break. This paper presents a case study of how a group of Latino parents carried out a process of liberation fueled by the generation of empowering community narratives (critical awareness leading to transformative action) that resulted from a community-university partnership. Participants initiated a process that led them to discover their own stories of oppression and create new stories; to deconstruct the dominant cultural narratives and modify existing ones; and to understand contexts for power sharing. This joint reflection and increased awareness propelled group members to take action by founding a grassroots organization to redress some of the injustices that were partly responsible for their oppression, thus generating shifts at the personal, relational, and collective levels. In light of the theory of liberation, we discuss the participants' development of critical awareness that led them to take action to address their unmet needs.

This paper presents work to identify factors affecting effectiveness of agri-business ventures (A-BVs) on the side of providers as perceived by their members. A survey was conducted among 95 members of A-BVs in Zanjan province, Iran. To collect data, a questionnaire was designed. Two distinct groups of A-BVs with low (group 1) and high (group 2) perceived (evaluated) levels of effectiveness were revealed. The study showed that there were significant differences between the two groups on important characteristics of A-BVs and their members. The study also found that there were statistically significant relationships between A-BVs' governance structure and capacity, management and organization characteristics and the perceived effectiveness, whereas there were no statistically significant relationships between A-BVs' advisory methods characteristic applied by members and the perceived effectiveness. Logistic regression results also showed that level of application of rules encouraging members' active participation in important decision makings, clear terms of reference to guide contracting procedures, roles, and responsibilities of parties involved, type of people served and geographical area of program coverage, and members' ability to use Information and Communication Technologies (ICTs) were predictors of the perceived (evaluated) effectiveness of A-BVs. The study showed that evaluation of members of effectiveness of A-BVs would not be the same. It is suggested that Iranian public agricultural extension organization, as responsible organization for monitoring and evaluating services conducted by A-BVs, considered these differences between members with different levels of some important variables. 2010 Elsevier Ltd.

Difficult laryngoscopy and tracheal intubation are occasionally encountered in children with congenital anomalies or micrognathia. However, no study has elucidated anatomical etiology in relation to craniofacial development. Two hundred ten patients aged 8 months-18 years were analyzed. We analyzed the lateral cephalograms of: (i) eight patients in whom laryngoscopy was anticipated as difficult before anesthesia and who were unable to be intubated by direct laryngoscopy and needed fiberoptic bronchoscopy (group A); (ii) 11 patients in whom laryngoscopy was anticipated as difficult before anesthesia but who were able to be intubated by direct laryngoscopy (group B); and (iii) 191 patients in whom laryngoscopy was anticipated as easy before anesthesia and was actually found to be easy (group C). Eight cephalometric parameters were measured and age-parameter relationships were plotted. Logistic regression analysis was performed to characterize group A children for each of the cephalometric variables. Apparently insufficient growth of the mandible was observed in the group A children. Furthermore, the group A children of aged <4 years had undeveloped maxilla, longer mandibular plane-hyoid distances (≥1.3 cm), and deeper depth of the oropharynx; those of aged ≥4 years showed increased inclination of the mandible (sella-nasion plane to mandibular plane angle of ≥46.5°). Difficult laryngoscopy and tracheal intubation are expected in children aged <4 years with lower-positioned hyoid bone caused by caudal larynx as well as undeveloped maxilla and mandible, and in those aged ≥4 years with increased inclination of the mandible as well as undeveloped mandible. © 2013 John Wiley & Sons Ltd.

Background Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Methodology/Principal Findings Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Conclusions/Significance Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF. PMID:26849126

Pharmacotherapy after myocardial infarction: disease management versus usual care.

2008-06-01

To evaluate the effectiveness of a disease management (DM) program compared with usual care on utilization of and adherence to key evidence-based therapies (angiotensin-converting enzyme [ACE] inhibitors/angiotensin II receptor blockers [ARBs], beta-blockers, and statins) after hospital discharge for patients with myocardial infarction (MI) in a managed care organization. Retrospective case-control cohort. Members were included if they were 18 years of age or older and had any medical claims for hospitalization for MI, defined as International Classification of Diseases, Ninth Revision, Clinical Modification, codes 410.xx, from January 1, 2002, to December 31, 2002. The index date was the first date of discharge for members with an MI diagnosis. Members were categorized into the active group (automatically enrolled in the DM program) or the control group (not enrolled in the program because their employer group did not purchase the benefit). Pharmacy claims were obtained for 12 months after the index date for ACE inhibitors, ARBs, beta-blockers, and statins. The study cohort included 250 members in the active group and 137 members in the control group. There were no statistical differences in utilization or time to first prescription fill of ACE inhibitors, ARBs, beta-blockers, and statins between the DM and usual care groups. Adherence to each of these therapies, as measured by medication possession ratio, was not statistically different between the 2 groups. Compared with usual care, participation in the DM program did not improve ACE inhibitor, ARB, statin, or beta-blocker utilization or adherence in members post-MI.

The use of the internet in data assimilation in rare diseases.

The incidence and prevalence of achalasia is 0.6/100,000 people per year and 1/10,000, respectively. It is difficult then for one center to accumulate a large cohort of patients. One study (Gut 33:1011,1992) described the presenting symptoms in only 38 patients. To approach this problem differently, we used the internet to access a larger patient population. Using search engines at Google and Yahoo, Inc., we identified achalasia support groups. We examined the most populated support group (YSG) and assembled the exchanged messages into 4 categories: support, symptoms, treatment, and diagnosis. Next, a survey modeled after a previous study (ibid) was composed and posted on a university-sponsored Web site for March 2003, advertised to YSG members, and then removed from the server. The results were entered into a database and analyzed. There were 6 support groups identified; 1 was foreign. The most populated site was the Yahoo, Inc., group with 298 active members. We analyzed the 3,222 messages posted from October 6, 2002 through October 5, 2003. The message composition was as follows: 67% support, 16% symptoms, 12% treatment, and 5% diagnosis. Of 298 Yahoo site members, we had 88 respondents to the survey from 9 countries. The data from 83 were analyzed (5 were not completed). Respondents were 66 women (55%), 29 men (24%), and 5 non-gender-identified respondents. They ranged in age from 6 to 72 years at time of diagnosis. In the 83 respondents, dysphagia symptoms were reported by 98%, regurgitation by 68%, chest pain by 81%, weight loss by 69%, and epigastric pain by 67%, similar to those reported in the study cited in Gut. The modalities used to evaluate these achalasia patients were as follows: 83% had monometry, 87% had radiography, and 89% had endoscopy. The mean time from symptom onset to diagnosis was 5 years. The treatments attempted on this population were balloon dilatation in 57%, botulinum toxin injection (Botox) in 8%, myotomy in 12%, by lifestyle/diet modification in 12%, and other treatments in 11%. We believe that the Internet can provide physician-researchers with useful information about common and uncommon diseases on a global basis. The Internet allows patients to voice concerns that they may not freely express to their doctor and provides a modality to collect data from a larger number of patients than may be available at any single institution.

Decision making in liver transplant selection committees: a multicenter study.

To receive a liver transplant, patients must first be placed on a waiting list-a decision made at most transplant centers by a multidisciplinary committee. The function of these committees has never been studied. To describe decision making in liver transplant committees and identify opportunities for process improvement. Observational multicenter study. 4 liver transplant centers in the United States. 68 members of liver transplant committees across the 4 centers. 63 meetings were observed, and 50 committee members were interviewed. Recorded transcripts and field notes were analyzed by using standard qualitative sociologic methods. Although the structure of the meetings varied by center, the process was uniform and primarily involved inductive reasoning to review possible reasons for patient exclusion. Patients were excluded if they were too well, too sick (in the setting of advanced liver disease), or too old or had nonhepatic comorbid conditions, substance abuse problems, or other psychosocial barriers. Dominant themes in the discussions included member angst over deciding who lived or died, a high correlation between psychosocial barriers to transplantation and the patient's socioeconomic status, and the influence of external forces on decision making. Unwritten center policies and confusion regarding advocacy versus stewardship roles were consistently identified as barriers to effective group decision making. The use of qualitative methods provides broad understanding but limits specific inferences. The 4 centers may not reflect the practices of every transplant center nationwide. The difficult decisions made by liver transplant committees are reasonably consistent and well-intentioned, but the process might be improved by having more explicit written policies and clarifying roles. This may inform resource allocation in other areas of medicine. The Greenwall Foundation and the National Institutes of Health.

2018-06-11

Using a novel human factors engineering approach, the Systems Engineering Initiative for Patient Safety model, we evaluated environmental service workers' (ESWs) perceptions of barriers and facilitators influencing adherence to the nationally mandated Department of Veterans Affairs Clostridium difficile infection (CDI) prevention bundle. A focus group of ESWs was conducted. Qualitative analysis was performed employing a visual matrix display to identify barrier/facilitator themes related to Department of Veterans Affairs CDI bundle adherence using the Systems Engineering Initiative for Patient Safety work system as a framework. Environmental service workers reported adequate cleaning supplies/equipment and displayed excellent knowledge of CDI hand hygiene requirements. Environmental service workers described current supervisory practices as providing an acceptable amount of time to clean CDI rooms, although other healthcare workers often pressured ESWs to clean rooms more quickly. Environmental service workers reported significant concern for CDI patients' family members as well as suggesting uncertainty regarding the need for family members to follow infection prevention practices. Small and cluttered patient rooms made cleaning tasks more difficult, and ESW cleaning tasks were often interrupted by other healthcare workers. Environmental service workers did not feel comfortable asking physicians for more time to finish cleaning a room nor did ESWs feel comfortable pointing out lapses in physician hand hygiene. Multiple work system components serve as barriers to and facilitators of ESW adherence to the nationally mandated Department of Veterans Affairs CDI bundle. Environmental service workers may represent an underappreciated resource for hospital infection prevention, and further efforts should be made to engage ESWs as members of the health care team.

Rationale Tobacco companies use advertising to target vulnerable populations, including youth, racial/ethnic minorities, and sexual minorities. Objective We sought to examine how personal identity affects support for population-specific anti-smoking advertisements that could serve as countermeasures to industry practices. Methods In 2014–2015, we surveyed probability phone samples of adults and adolescents (n = 6,139) and an online convenience sample of adults (n = 4,137) in the United States. We experimentally varied the description of tobacco industry marketing practices (no description, general, or specific to a target group). The four prevention target groups were teens; African Americans; Latinos; and gays, lesbians, and bisexuals (GLBs). Participants were either members or non-members of their prevention target group. Results Support was highest for anti-smoking advertisements targeting teens, moderate for Latinos and African Americans, and lowest for GLBs. In-group members expressed higher support than out-group members when anti-smoking advertisements targeted African Americans, Latinos, and GLBs (all p < .05). However, when teens were the target prevention group, in-group members expressed lower support than out-group members (p < .05). The description of industry marketing practices did not have an effect. Results were similar across the phone and online studies. Conclusions Our findings suggest that the public strongly supports advertisements to prevent smoking among teens, but support for similar efforts among other vulnerable populations is comparatively low. Anti-smoking campaigns for vulnerable populations may benefit from a greater understanding of the role of social identity in shaping public support for such campaigns. PMID:28427731

To better focus efforts in recruiting psychoanalytic candidates, current candidates' demographics, practice patterns, and satisfaction with psychoanalytic training were investigated. An anonymous web-based survey was distributed by e-mail to all candidates subscribing to the affiliate member e-mail list in 2009-2010. Surveys were completed by 226 of 565 affiliate members, for a return rate of 40%. The majority of respondents were women 45 to 64 years of age, married, with a doctoral degree, in private practice, with an annual household income of over $100,000. Most candidates devoted 11 to 30 hours a week to training and had no analysts or candidates in their workplace. Almost half had considered training for more than four years before matriculation, with financial issues cited most frequently as delaying entry. Over 80% of respondents were satisfied with their training. The most frequently cited reasons for dissatisfaction were a negative institute atmosphere, concerns about teaching or the curriculum, and difficulty finding cases. Candidates in training for eight years or more accounted for almost 20% of the group and were more often dissatisfied with training. This study demonstrates that the majority of current candidates are satisfied with training but suggests that recruitment may become increasingly difficult unless factors related to time, cost, case finding, graduation requirements, and institute atmosphere can be addressed.

The prominence of sedentary behavior research in health science has grown rapidly. With this growth there is increasing urgency for clear, common and accepted terminology and definitions. Such standardization is difficult to achieve, especially across multi-disciplinary researchers, practitioners, and industries. The Sedentary Behavior Research Network (SBRN) undertook a Terminology Consensus Project to address this need. First, a literature review was completed to identify key terms in sedentary behavior research. These key terms were then reviewed and modified by a Steering Committee formed by SBRN. Next, SBRN members were invited to contribute to this project and interested participants reviewed and provided feedback on the proposed list of terms and draft definitions through an online survey. Finally, a conceptual model and consensus definitions (including caveats and examples for all age groups and functional abilities) were finalized based on the feedback received from the 87 SBRN member participants who responded to the original invitation and survey. Consensus definitions for the terms physical inactivity, stationary behavior, sedentary behavior, standing, screen time, non-screen-based sedentary time, sitting, reclining, lying, sedentary behavior pattern, as well as how the terms bouts, breaks, and interruptions should be used in this context are provided. It is hoped that the definitions resulting from this comprehensive, transparent, and broad-based participatory process will result in standardized terminology that is widely supported and adopted, thereby advancing future research, interventions, policies, and practices related to sedentary behaviors.

Responsibility for quality improvement and patient safety: hospital board and medical staff leadership challenges.

2010-07-01

Concern about the quality and safety of health care persists, 10 years after the 1999 Institute of Medicine report To Err is Human. Despite growing awareness of quality and safety risks, and significant efforts to improve, progress is difficult to measure. Hospital leaders, including boards and medical staffs, are accountable to improve care, yet they often address this duty independently. Shared responsibility for quality and patient safety improvement presents unique challenges and unprecedented opportunities for boards and medical staffs. To capitalize on the pressure to improve, both groups may benefit from a better understanding of their synergistic potential. Boards should be educated about the quality of care provided in their institutions and about the challenges of valid measurement and accurate reporting. Boards strengthen their quality oversight capacity by recruiting physicians for vacant board seats. Medical staff members strengthen their role as hospital leaders when they understand the unique duties of the governing board. A quality improvement strategy rooted in synergistic efforts by the board and the medical staff may offer the greatest potential for safer care. Such a mutually advantageous approach requires a clear appreciation of roles and responsibilities and respect for differences. In this article, we review these responsibilities, describe opportunities for boards and medical staffs to collaborate as leaders, and offer recommendations for how boards and medical staff members can address the challenges of shared responsibility for quality of care.

The use and abuse of religious beliefs in dividing and conquering between socially marginalized groups: the same-sex marriage debate.

PubMed

Greene, Beverly

2009-11-01

This article discusses the use and abuse of religious beliefs and their role in divide-and-conquer strategies. Divide-and-conquer strategies are engaged to disrupt potential coalitions between and among marginalized group members, specifically sexual minority groups and people of color. Tensions between these groups have been exacerbated by the debate on same-sex marriage and comparisons between the discriminatory treatment of each group. A component of this discussion includes a brief exploration of one of the historical abuses of religious doctrine used to legitimize the marginalization of people of color and sexual minorities in the United States. For African Americans, one form of marginalization was reflected in criminalizing interracial marriage, and for members of sexual minority groups, a form of marginalization is denying group members the right to marry. The author also explores culturally competent and respectful disciplinary and clinical responses to religiously derived prejudice against sexual minority group members and people of color and discusses the implications for multicultural discourse.

Discovery of a Free-Floating Double Planet?

NASA Astrophysics Data System (ADS)

Kohler, Susanna

2017-07-01

An object previously identified as a free-floating, large Jupiter analogturns out to be two objects each with the mass of a few Jupiters. This system is the lowest-mass binary weve ever discovered.Tracking Down Ages2MASS J111932541137466 is thought to be a member of the TW Hydrae Association, a group of roughly two dozen young stars moving together in the solar neighborhood. [University of Western Ontario/Carnegie Institution of Washington DTM/David Rodriguez]Brown dwarfs represent the bottom end of the stellar mass spectrum, with masses too low to fuse hydrogen (typically below 75-80 Jupiter masses). Observing these objects provides us a unique opportunity to learn about stellar evolution and atmospheric models but to properly understand these observations, we need to determine the dwarfs masses and ages.This is surprisingly difficult, however. Brown dwarfs cool continuously as they age, which creates an observational degeneracy: dwarfs of different masses and ages can have the same luminosity, making it difficult to infer their physical properties from observations.We can solve this problem with an independent measurement of the dwarfs masses. One approach is to find brown dwarfs that are members of nearby stellar associations called moving groups. The stars within the association share the same approximate age, so a brown dwarfs age can be estimated based on the easier-to-identify ages of other stars in the group.An Unusual BinaryRecently, a team of scientists led by William Best (Institute for Astronomy, University of Hawaii) were following up on such an object: the extremely red, low-gravity L7 dwarf 2MASS J111932541137466, possibly a member of the TW Hydrae Association. With the help of the powerful adaptive optics on the Keck II telescope in Hawaii, however, the team discovered that this Jupiter-like objectwas hiding something: its actually two objects of equal flux orbiting each other.Keck images of 2MASS J111932541137466 reveal that this object is actually a binary system. A similar image of another dwarf, WISEA J1147-2040, is shown at bottom left for contrast: this one does not show signs of being a binary at this resolution. [Best et al. 2017]To learn more about this unusual binary, Best and collaborators began by using observed properties like sky position, proper motion, and radial velocity to estimate the likelihood that 2MASS J111932541137466AB is, indeed, a member of the TW Hydrae Association of stars. They found roughly an 80% chance that it belongs to this group.Under this assumption, the authors then used the distance to the group around 160 light-years to estimate that the binarys separation is 3.9 AU. The assumed membership in the TW Hydrae Association also provides binarys age: roughly 10 million years. This allowed Best and collaborators to estimate the masses and effective temperatures of the components from luminosities and evolutionary models.Planetary-Mass ObjectsThe positions of 2MASS J111932541137466A and B on a color-magnitude diagram for ultracool dwarfs. The binary components lie among the faintest and reddest planetary-mass L dwarfs. [Best et al. 2017]The team found that each component is a mere 3.7 Jupiter masses, placing them in the fuzzy region between planets and stars. While the International Astronomical Union considers objects below the minimum mass to fuse deuterium (around 13 Jupiter masses) to be planets, other definitions vary, depending on factors such as composition, temperature, and formation. The authors describe the binary as consisting of two planetary-mass objects.Regardless of its definition, 2MASS J111932541137466AB qualifies as the lowest-mass binary discovered to date. The individual masses of the components also place them among the lowest-mass free-floating brown dwarfs known. This system will therefore be a crucial benchmark for tests of evolutionary and atmospheric models for low-mass stars in the future.CitationWilliam M. J.

Objectives To elucidate the difficulties physicians have when a family member becomes ill and to elicit their underlying causes. Design Using a key informant technique, we solicited chairs of family medicine departments for their experiences with the health care provided to seriously ill family members. We then conducted in-depth, semistructured telephone interviews that were then transcribed, coded, and labeled for themes. Subjects 8 senior family physicians whose parents had experienced a serious illness within the past 5 years. All of the subjects reflected on experiences stemming from their fathers' illness. Results These physicians faced competing expectations: at an internal level, those of their ideal role in their family and their ideal professional identity; and at an external level, those originating from other family members and from other physicians. Reconciling these conflicting expectations was made more difficult by what they deemed to be suboptimal circumstances of the modern health care system. Conclusions Conflicting rules of appropriate conduct, compounded by the inadequacies of modern health care, make the role of physician-family member especially challenging. The medical profession needs a clearer, more trenchant understanding of this role. PMID:11577049

Different views on ethics: how animal ethics is situated in a committee culture.

PubMed

Ideland, M

2009-04-01

Research that includes non-human animal experimentation is fundamentally a dilemmatic enterprise. Humans use other animals in research to improve life for their own species. Ethical principles are established to deal with this dilemma. But despite this ethical apparatus, people who in one way or another work with animal experimentation have to interpret and understand the principles from their individual points of view. In interviews with members of Swedish animal ethics committees, different views on what the term ethics really means were articulated. For one member, the difficult ethical dilemma of animal experimentation is the lack of enriched cages for mice. For another, the ethical problem lies in regulations restraining research. A third member talks about animals' right not to be used for human interests. These different views on "ethics" intersect once a month in the animal ethics committee meetings. There is no consensus on what constitutes the ethical problem that the members should be discussing. Therefore, personal views on what ethics means, and hierarchies among committee members, characterise the meetings. But committee traditions and priorities of interpretation as well are important to the decisions. The author discusses how "ethics" becomes situated and what implications this may have for committees' decisions.

Investigation on the Effect of Initial Welding Imperfection on Fatigue strength of Tubular Member by FEM

2018-04-01

Steel tube structure is used for steel structure such as offshore platform, bridges and so on. Also, all circular members of tubular structures are mainly connected by welding. When the steel tubular structures are subjected to repeated loading, not only the load carrying capacity is reduced but also fatigue cracks may develop at the joint part of steel tubular members which are connected by welding. Carrying out welding, welding initial imperfection such as welding deformation and residual stress are inevitably generated at weld part. It was well known that the effect of welding residual and welding deformation on fatigue strength. However, It’s not clear which affects fatigue strength more. However, it’s difficult to clear the effect on fatigue strength by experiment. To clarify these effect, fatigue analysis was carried out by FEM which is based on continuum damage mechanics. On the other hand, coupled three-dimensional non-steady heat conduction analysis, and the thermal elastic-plastic analysis was carried out to reproduce the initial weld state of tubular member. From the result, not only the fatigue strength of welded tubular member but also the fatigue life could be found by FEM fatigue analysis.

Influence of the helicopter environment on patient care capabilities: flight crew perceptions

1995-01-01

INTRODUCTION: Flight crew perceptions of the effect of the rotary-wing environment on patient-care capabilities have not been subject to statistical analysis. We hypothesized that flight crew members perceived significant difficulties in performing patient-care tasks during air medical transport. METHODS: A survey was distributed to a convenience sample of flight crew members from 20 flight programs. Respondents were asked to compare the difficulty of performing patient-care tasks in rotary-wing and standard (emergency department or intensive care unit) settings. Demographic data collected on respondents included years of flight experience, flights per month, crew duty position and primary aircraft in which the respondent worked. Statistical analysis was performed as appropriate using Student's t-test, type III sum of squares, and analysis of variance. Alpha was defined as p < 0.05. RESULTS: Fifty-five percent of programs (90 individuals) responded. All tasks were significantly rated more difficult in the rotary-wing environment. Ratings were not significantly correlated with flight experience, duty position, flights per month or aircraft used. CONCLUSIONS: We conclude that the performance of patient-care tasks are perceived by air medical flight crew to be significantly more difficult during rotary-wing air medical transport than in hospital settings.

Ethnic diversity and value sharing: A longitudinal social network perspective on interactive group processes.

Meeussen, Loes; Agneessens, Filip; Delvaux, Ellen; Phalet, Karen

2018-04-01

People often collaborate in groups that are increasingly diverse. As research predominantly investigated effects of diversity, the processes behind these effects remain understudied. We follow recent research that shows creating shared values is important for group functioning but seems hindered in high diversity groups - and use longitudinal social network analyses to study two interpersonal processes behind value sharing: creating relations between members or 'social bonding' (network tie formation and homophily) and sharing values - potentially through these relationships - or 'social norming' (network convergence and influence). We investigate these processes in small interactive groups with low and high ethnic diversity as they collaborate over time. In both low and high diversity groups, members showed social bonding and this creation of relations between members was not organized along ethnic lines. Low diversity groups also showed social norming: Members adjusted their relational values to others they liked and achievement values converged regardless of liking. In high diversity groups, however, there was no evidence for social norming. Thus, ethnic diversity seems to especially affect processes of social norming in groups, suggesting that targeted interventions should focus on facilitating social norming to stimulate value sharing in high diversity groups. © 2018 The British Psychological Society.

Investigating the purpose of an online discussion group for health professionals: a case example from forensic occupational therapy.

PubMed

Dieleman, Crystal; Duncan, Edward A S

2013-07-03

Thousands of health-related online discussion groups are active world-wide however, very little is known about the purpose and usefulness of such groups. In 2003 an online discussion group called 'forensic occupational therapy' was established in the United Kingdom. This group was examined to gain an understanding of the purpose and use of online discussion groups for health professionals who may be practically and geographically isolated from others in similar areas of practice. Following a case study design, descriptive characteristics on members' locations and number of posts were collected from the forensic occupational therapy online discussion group. Eight years of posts (2003-2011) were examined using a theoretical thematic analysis process to identify and describe the purposes for which members were using the group. Members from 20 countries contributed to the discussion group; the vast majority of posts being from members in the United Kingdom. Activity within the group was consistently high for the first five years however, activity within the group declined in the final three years. Six purposes for which members use the online discussion group were identified: seeking and giving advice, networking, requesting and sharing material resources, service development, defining the role of occupational therapists, and student learning. Findings suggest that health professionals in specialized and often isolated areas of practice are keen to connect with colleagues and learn from each other's experiences. The main purposes for which the online discussion group was used could be summarized as communication, information sharing and networking; though activity within the group declined significantly during the last three years of the data collection period. This raises questions about the sustainability of online discussion groups within the rapidly developing social media environment.

Anthropologists have documented substantial cross-society variation in people's willingness to treat strangers with impartial, universal norms versus favoring members of their local community. Researchers have proposed several adaptive accounts for these differences. One variant of the pathogen stress hypothesis predicts that people will be more likely to favor local in-group members when they are under greater infectious disease threat. The material security hypothesis instead proposes that institutions that permit people to meet their basic needs through impartial interactions with strangers reinforce a tendency toward impartiality, whereas people lacking such institutions must rely on local community members to meet their basic needs. Some studies have examined these hypotheses using self-reported preferences, but not with behavioral measures. We conducted behavioral experiments in eight diverse societies that measure individuals' willingness to favor in-group members by ignoring an impartial rule. Consistent with the material security hypothesis, members of societies enjoying better-quality government services and food security show a stronger preference for following an impartial rule over investing in their local in-group. Our data show no support for the pathogen stress hypothesis as applied to favoring in-groups and instead suggest that favoring in-group members more closely reflects a general adaptive fit with social institutions that have arisen in each society.

We report the results of a simulation study in which we explore the joint effect of group absorptive capacity (as the average individual rationality of the group members) and cognitive distance (as the distance between the most rational group member and the rest of the group) on the emergence of collective rationality in groups. We start from empirical results reported in the literature on group rationality as collective group level competence and use data on real-life groups of four and five to validate a mathematical model. We then use this mathematical model to predict group level scores from a variety of possible group configurations (varying both in cognitive distance and average individual rationality). Our results show that both group competence and cognitive distance are necessary conditions for emergent group rationality. Group configurations, in which the groups become more rational than the most rational group member, are groups scoring low on cognitive distance and scoring high on absorptive capacity.

[Classical and new approaches in laboratory diagnosis of viridans streptococci].

PubMed

Ergin, Alper

2010-07-01

Viridans group streptococci (VGS) are gram-positive microorganisms that can form alpha-hemolytic colonies on sheep blood agar. They reside as normal flora in oral cavity, respiratory, gastrointestinal, urogenital tract and on skin. They can cause bacteremia, endocarditis, meningitis and septicemia following dental procedures. The diagnosis of VGS are difficult since the taxonomic classification and species na-mes may change due in time. Viridans group streptococci are classified into 5 groups (Sanguinis, Mitis, Mutans, Salivarius, Anginosus) according to biochemical reactions and 16S rRNA sequencing. Since Streptococcus pneumoniae is a member of the Mitis group, the other important species in this group deserves investigation. Genetic exchange between Streptococcus mitis, Streptococcus oralis and S.pneumoniae by transformation and lysis mechanisms occur continously as they share the same anatomical region. These mechanisms play role in exchanging capsular and antibiotic resistance genes between these species. The cultivation of VGS usually starts with the inoculation of various patient specimens into sheep blood agar and the detection of alpha-hemolytic colonies. Observation of gram-positive cocci microscopically, the detection of optochin-resistant and bile insoluble colonies with few exceptions are the further important steps in laboratory diagnosis. VGS are then identified at species level by using biochemical reactions, automated diagnostic systems and molecular methods. The last step in the laboratory diagnosis of VGS is antibiotic susceptibility testing which is of outmost importance as penicillin and erythromycin resistance are on rise. In this review article, classification of VGS, similarities between S.pneumoniae and Mitis group streptococci and the laboratory diagnosis of VGS have been discussed.

Outcome and self-confidence scores were used as dependent variables. The 48 participants were randomly assigned into four groups. Group A received correction cues and positive feedback. Group B received cues on errors of execution. Group C received positive feedback, correction cues and error cues. Group D was the control group. A pre, post and a retention test was conducted. A three way analysis of variance ANOVA (4 groups X 2 task difficulty X 3 measures) with repeated measures on the last factor revealed significant interactions for each depended variable. All the corrective feedback methods groups, increased their outcome scores over time for the easy skill, but only groups A and C for the difficult skill. Groups A and B had significantly better outcome scores than group C and the control group for the easy skill on the retention test. However, for the difficult skill, group C was better than groups A, B and D. The self confidence scores of groups A and C improved over time for the easy skill but not for group B and D. Again, for the difficult skill, only group C improved over time. Finally a regression analysis depicted that the improvement in performance predicted a proportion of the improvement in self confidence for both the easy and the difficult skill. It was concluded that when young athletes are taught skills of different difficulty, different type of instruction, might be more appropriate in order to improve outcome and self confidence. A more integrated approach on teaching will assist coaches or physical education teachers to be more efficient and effective. Key pointsThe type of the skill is a critical factor in determining the effectiveness of the feedback types.Different instructional methods of corrective feedback could have beneficial effects in the outcome and self-confidence of young athletesInstructions focusing on the correct cues or errors increase performance of easy skills.Positive feedback or correction cues increase self-confidence of easy skills but only the combination of error and correction cues increase self confidence and outcome scores of difficult skills.

Group biases guide social interactions by promoting in-group favouritism, but the neural mechanisms underpinning group biases remain unclear. While neuroscience research has shown that distributed brain circuits are associated with seeing in-group and out-group members as "us" and "them", it is less clear how these networks exchange signals. This fMRI study uses functional connectivity analyses to investigate the contribution of functional integration to group bias modulation of person perception. Participants were assigned to an arbitrary group and during scanning they observed bodies of in-group or out-group members that cued the recall of positive or negative social knowledge. The results showed that functional coupling between perceptual and cognitive neural networks is tuned to particular combinations of group membership and social knowledge valence. Specifically, coupling between body perception and theory-of-mind networks is biased towards seeing a person that had previously been paired with information consistent with group bias (positive for in-group and negative for out-group). This demonstrates how brain regions associated with visual analysis of others and belief reasoning exchange and integrate signals when evaluating in-group and out-group members. The results update models of person perception by showing how and when interplay occurs between perceptual and extended systems when developing a representation of another person.

Society members whose research publication during the past 125 yr had an important impact on the discipline of physiology were featured at the American Physiological Society (APS)'s 125th Anniversary symposium. The daunting and challenging task of identifying and selecting significant publications was assumed by the Steering Committee of the History of Physiology Interest Group, who requested recommendations and rationales from all Sections, select Interest Groups, and active senior APS members. The request resulted in recommendations and rationales from nine Sections, one Interest Group, and 28 senior members, identifying 38 publications and 43 members for recognition purposes. The publication recommendations included 5 individuals (Cournand, Erlanger, Gasser, Hubel, and Wiesel) whose research significantly contributed to their selection for the Nobel Prize in Medicine or Physiology, 4 individuals who received multiple recommendations [i.e., Cannon (3), Curran (2), Fenn (3), and Hamilton (2)], and 11 members who had been APS Presidents. Of the recommended articles, 33% were from the American Journal of Physiology, with the earliest being published in 1898 (Cannon) and the latest in 2007 (Sigmund). For the brief oral presentations, the History of Physiology Steering Committee selected the first choices of the Sections or Interest Group, whereas rationales and representation of the membership were used for the presentations by senior members.

This research examines how moral values regulate the behavior of individual group members. It argues that group members behave in line with moral group norms because they anticipate receiving ingroup respect when enacting moral values that are shared by ingroup members. Data from two experimental studies offer evidence in support. In Study 1 (N = 82), morality-based (but not competence-based) ingroup norms determined whether members of a low-status group opted for individual versus collective strategies for status improvement. This effect was mediated by anticipated ingroup respect and emerged regardless of whether group norms prescribed collectivistic or individualistic behavior. These effects were replicated in Study 2 (N = 69), where no comparable effect was found as a result of moral norms communicated by a higher status outgroup. This indicates that social identity implications rather than interdependence or more generic concerns about social approval or importance of cooperation drive these effects.

Prosocial emotions and helping: the moderating role of group membership.

In this article, the authors introduce and test a group-level perspective on the role of empathy and interpersonal attraction in helping. In line with our predictions, Study 1, a longitudinal field study of 166 AIDS volunteers, confirmed that empathy was a stronger predictor of helping when the recipient of assistance was an in-group member than when that person was an out-group member. Also as hypothesized, attraction was a stronger predictor of helping when the recipient was an out-group member than when that person was an in-group member. Study 2 replicated and further extended these results in a laboratory experiment on spontaneous helping of a person with hepatitis. Strengthening the validity of the findings, in both studies the effects of empathy and attraction held up even when the authors statistically controlled for potential alternative predictors of helping. The theoretical and practical implications of these findings for helping in intergroup contexts are discussed. ((c) 2005 APA, all rights reserved).

To examine the use of online social networking for cardiovascular care using Facebook. All posts and comments in a Facebook group between June 2011 and May 2012 were reviewed, and a survey was conducted. A total of 298 members participated. Of the 277 wall posts, 26.7% were question posts requesting rapid replies, and 50.5% were interesting cases shared with other members. The median response time for the question posts was 16 min (IQR 8–47), which tended to decrease as more members joined the group. Many members (37.4%) accessed the group more than once a day, and more than half (64%) monitored the group posts in real time with automatic notifications of new posts. Most members expressed confidence in the content posted. Facebook enables online social networking between physicians in near-real time and appears to be a useful tool for physicians to share clinical experience and request assistance in decision-making.

Farmer, F. H.

1981-01-01

The calculation of indices of phytoplankton population composition from chlorophyll a fluorescence at 685 nm excited by narrow band light at 454 and 539 nm is discussed. The ratio of the fluorescence excited by light of these two wavelengths is a function of the distribution of the phytoplankton between two color groups, designated the golden-brown and the green. The golden-brown group consists of those species which have the highly photosynthetically active carotenoid-chlorophyll-a-protein complexes, i.e. members of the classes Bacillariophyceae, diatoms Dinophyceae, dinoflagellates, and some members of the class Prymnesiophyceae. The green color group consists those species of phytoplankton which apparently lack those complexes, i.e. members of the classes Chlorophyceae, Euglenophyceae, Prasinophyceae, Eustigmatophyceae, Xanthophyceae, and a few members of the Prymnesiophyceae. A few species of phytoplankton appear to have intermediate characteristics, and would apparently belong to neither group. Most of these species are members of the class Cryptophyceae. The composition index for this class is examined in detail.

Initial prejudices create cross-generational intergroup mistrust

The present investigation modeled the emergence and persistence of intergroup bias and discrimination in artificial societies. Initial unfair prejudices held by members of a dominant group elicit confirmatory behavior (diminished cooperation) from members of a subordinate group via a self-fulfilling prophecy. Further, when individual learning is tempered by conformity to peers, inaccurate beliefs about the stigmatized subordinate group persist long-term. Even completely replacing dominant group members with enlightened individuals through generational change is inadequate to break the cycle of intergroup distrust and non-collaboration. The longer the enlightenment of a society is delayed, the more intergroup trust is irretrievably lost. PMID:29694405

Garnet: featured mineral group at the 1993 Tucson Show

The garnets are a common but complex group of minerals. They are perhaps the mineral kingdom's best example of solid solution: a relationship in which minerals have chemical compositions that are intermediate between two or more ideal end-member species. In garnet, we deal with a complex group of solid-solution series between as many as 14 end-member minerals. The varying intergradations of solid solution between these different end-members help to explain the garnet group's variety of color, environment of occurrence, gem use, and variation in such physical properties as specific gravity, refractive index, and hardness. -from Author

Advancing understanding in the face of data limitations and difficult conditions: Estimating storage contributions to streamflow in Tanzania's rapidly developing Kilombero Valley

Robust natural variability and experimental design may help to overcome the data limitations and difficult conditions that typify much of the global south. This, in turn, can facilitate the application of advanced techniques to help inform management with science (which is sorely needed for guiding development). As an example on this concept, we used a limited amount of weekly water chemistry as well as stable water isotope data to perform end-member mixing analysis in a glue frame work (G-EMMA) in one main catchment and two sub-catchments of Kilombero Valley, Tanzania. How water interacts across the various storages in this region, which has been targeted for rapid agricultural intensification and expansion, is still largely unknown making estimation of potential impacts (not to mention sustainability) associated with various development scenarios difficult. Our results showed that there were, as would be expected, considerable uncertainties related to the characterization of end-members in this remote system. Regardless, some robust estimates could be made on contributions to seasonal streamflow variability. For example, it appears that there is a low connectivity between the deep groundwater and the stream system throughout the year. Also, there is a considerable wetting up period required before overland flow occurs. We demonstrate that the apparent miss-match between state-of-the-science techniques and data limitations (not to mention the issues associated with difficult working environments) can be bridged by leveraging experimental design and natural system variability. This is promising as we seek to advance our science in more and more remote (and in particular developing) regions to allow for important improvements for management of less and less available resources. Thus, in spite of large uncertainties this work highlights how research may still provide an improved system understanding of hydrological flows even when working under less than perfect conditions.

Evolving Multi Rover Systems in Dynamic and Noisy Environments

Tumer, Kagan; Agogino, Adrian

In this chapter, we address how to evolve control strategies for a collective: a set of entities that collectively strives to maximize a global evaluation function that rates the performance of the full system. Addressing such problems by directly applying a global evolutionary algorithm to a population of collectives is unworkable because the search space is prohibitively large. Instead, we focus on evolving control policies for each member of the collective, where each member is trying to maximize the fitness of its own population. The main difficulty with this approach is creating fitness evaluation functions for the members of the collective that induce the collective to achieve high performance with respect to the system level goal. To overcome this difficulty, we derive member evaluation functions that are both aligned with the global evaluation function (ensuring that members trying to achieve high fitness results in a collective with high fitness) and sensitive to the fitness of each member (a member's fitness depends more on its own actions than on actions of other members). In a difficult rover coordination problem in dynamic and noisy environments, we show how to construct evaluation functions that lead to good collective behavior. The control policy evolved using aligned and member-sensitive evaluations outperforms global evaluation methods by up to a factor of four. in addition we show that the collective continues to perform well in the presence of high noise levels and when the environment is highly dynamic. More notably, in the presence of a larger number of rovers or rovers with noisy sensors, the improvements due to the proposed method become significantly more pronounced.

Master indenture: capital financing for health care systems.

PubMed

Fisher, B; Zimmerman, R J

1984-04-01

The master indenture enables members of multiinstitutional health care systems to finance capital programs and expansions by borrowing on the basis of systemwide revenues and assets. Participation in a master indenture financing may be structured in two ways. In a restricted group, only the parent organization issues notes, and only the parent is directly liable for the debt. To ensure that each member's revenues flow to the parent, the latter must have sole member status and be permitted to approve subsidiaries' debts, budgets, amendments to articles and bylaws of incorporation, and selection of trustees. Each entity's articles and bylaws must permit it to support the system members' common charitable purpose. In contrast, members of an obligated group have direct joint and several liability for master indenture notes. If one subsidiary misses a payment, the parent can call for payment from other obligated group members. Limitations on a member's obligation to support system debt in case of insolvency or bankruptcy may be included in the master indenture provisions. Whichever structure is selected, the amount of debt that can be incurred is based on the institutions' combined financial statements. The master indenture thus allows financially weak institutions to benefit from the credit strengths of stranger system members and permits the parent organization to control members' access to capital markets.
