    The Understanding Research series focuses on the process of writing up social research. The series is broken down into three categories: Understanding Statistics, Understanding Measurement, and Understanding Qualitative Research. The books provide researchers with guides to understanding, writing, and evaluating social research. Each volume demonstrates how research should be represented, including how to write up the methodology as well as the research findings. Each volume also reviews how to appropriately evaluate published research. Focus Group Discussions addresses the challenges associated with conducting and writing focus group research. It provides detailed guidance on the practical and theoretical considerations in conducting focus group discussions including: designing the discussion guide, recruiting participants, training a field team, moderating techniques and ethical considerations. Monique Hennink describes how a methodology section is read and evaluated by others, such as journal reviewers or ...

    Various alternative methods are being used in many medical colleges to reinforce didactic lectures in physiology. Small group teaching can take on a variety of different tasks such as problem-solving, role play, discussions, brainstorming, and debate. Research has demonstrated that group discussion promotes greater synthesis and retention of materials. The aims of this study were to adopt a problem-solving approach by relating basic sciences with the clinical scenario through self-learning. To develop soft skills, to understand principles of group dynamics, and adopt a new teaching learning methodology. Experimental study design was conducted in Phase I 1(st) year medical students of 2014-2015 batch (n = 120). On the day of the session, the students were grouped into small groups (15 each). The session started with the facilitator starting off the discussion. Feedback forms from five students in each group was taken (n = 40). A five point Likert scale was used ranging from strongly agree to strongly disagree. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Our results show that 70% of the students opined that small group discussion were interactive, friendly, innovative, built interaction between teacher and student. Small group discussion increased their thought process and helped them in better communication. The small group discussion was interactive, friendly, and bridged the gap between the teacher and student. The student's communication skills are also improved. In conclusion, small group discussion is more effective than the traditional teaching methods.

    Groups of individuals can sometimes make more accurate judgments than the average individual could make alone. We tested whether this group advantage extends to lie detection, an exceptionally challenging judgment with accuracy rates rarely exceeding chance. In four experiments, we find that groups are consistently more accurate than individuals in distinguishing truths from lies, an effect that comes primarily from an increased ability to correctly identify when a person is lying. These experiments demonstrate that the group advantage in lie detection comes through the process of group discussion, and is not a product of aggregating individual opinions (a "wisdom-of-crowds" effect) or of altering response biases (such as reducing the "truth bias"). Interventions to improve lie detection typically focus on improving individual judgment, a costly and generally ineffective endeavor. Our findings suggest a cheap and simple synergistic approach of enabling group discussion before rendering a judgment.

    We led two discussion groups during the 2007 National GAP Conference. These discussion groups provided information to help develop a survey of National Gap Analysis Program (GAP) data users. One group discussed technical issues, and the second group discussed the use of GAP data for decisionmaking. Themes emerging from the technical issues group included concerns about data quality, need for information on how to use data, and passive data distribution. The decisionmaking discussion included a wide range of topics including the need to understand presentation of information, the need to connect with and understand users of data, the revision of GAP's mission, and the adaptability of products and data. The decisionmaking group also raised concerns regarding technical issues. One conclusion is that a deep commitment to ongoing information transfer and support is a key component of success for the GAP program.

    2008-03-01

    Focus group discussion is a research methodology in which a small group of participants gather to discuss a specified topic or an issue to generate data. The main characteristic of a focus group is the interaction between the moderator and the group, as well as the interaction between group members. The objective is to give the researcher an understanding of the participants' perspective on the topic in discussion. Focus groups are rapidly gaining popularity in health and medical research. This paper presents a general introduction of the use of focus groups as a research tool within the context of health research, with the intention of promoting its use among researchers in healthcare. A detailed methodology for the conduct of focus groups and analysis of focus group data are discussed. The potentials and limitations of this qualitative research technique are also highlighted.

    Research has shown that group discussion can increase intergroup prejudice and discrimination. However, we know little about the process by which discussion has this effect. Therefore, four studies were conducted in a real-world context to investigate this process. Results suggest that discussing a negative societal stereotype (relative to individual rumination in Studies 1 and 3 and alternative discussions in Studies 2 and 3) increases intentions to engage in discrimination against the out-group target of the stereotype. This is mediated by the formation of an in-group norm which supports discrimination (Study 1) and the extent to which the discussion validates the stereotype (Study 2). A fourth study manipulated the extent to which consensus on the negative stereotype was reached through discussion. When the discussion ended in consensus, participants have greater intention to undertake collective action against the stereotyped out-group, mediated by a congruent in-group norm. These results provide evidence that the process by which discussion increases intergroup discrimination is via the formation of discriminatory local group norms. ©2010 The British Psychological Society.

    Increasing interests have been paid to nanofluids because of the intriguing heat transfer enhancement performances presented by this kind of promising heat transfer media. We produced a series of nanofluids and measured their thermal conductivities. In this article, we discussed the measurements and the enhancements of the thermal conductivity of a variety of nanofluids. The base fluids used included those that are most employed heat transfer fluids, such as deionized water (DW), ethylene glycol (EG), glycerol, silicone oil, and the binary mixture of DW and EG. Various nanoparticles (NPs) involving Al2O3 NPs with different sizes, SiC NPs with different shapes, MgO NPs, ZnO NPs, SiO2 NPs, Fe3O4 NPs, TiO2 NPs, diamond NPs, and carbon nanotubes with different pretreatments were used as additives. Our findings demonstrated that the thermal conductivity enhancements of nanofluids could be influenced by multi-faceted factors including the volume fraction of the dispersed NPs, the tested temperature, the thermal conductivity of the base fluid, the size of the dispersed NPs, the pretreatment process, and the additives of the fluids. The thermal transport mechanisms in nanofluids were further discussed, and the promising approaches for optimizing the thermal conductivity of nanofluids have been proposed.

    2013-05-01

    A robust finding in social dilemmas research is that individual group members are more likely to act cooperatively if they are given the chance to discuss the dilemma with one another. The authors investigated whether imagining a group discussion may represent an effective means of increasing cooperative behavior in the absence of the opportunity for direct negotiation among decision makers. Five experiments, utilizing a range of task variants, tested this hypothesis. Participants engaged in a guided simulation of the progressive steps required to reach a cooperative consensus within a group discussion of a social dilemma. Results support the conclusion that imagined group discussion enables conscious processes that parallel those underlying the direct group discussion and is a strategy that can effectively elicit cooperative behavior. The applied potential of imagined group discussion techniques to encourage more socially responsible behavior is discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved

  11. The group discussion effect: integrative processes and suggestions for implementation.

    Science.gov (United States)

    Meleady, Rose; Hopthrow, Tim; Crisp, Richard J

    2013-02-01

    One of the most consistent findings in experimental social dilemmas research is the positive effect group discussion has on cooperative behavior. At a time when cooperation and consensus is critical to tackle global problems, ranging from debt to deforestation, understanding the dynamics of group discussion is a pressing need. Unfortunately, research investigating the underlying processes and implementation of the effect has been inconclusive. The authors present a critical review of existing explanations and integrate these perspectives into a single process model of group discussion, providing a more complete theoretical picture of how interrelated factors combine to facilitate discussion-induced cooperation. On the basis of this theoretical analysis, they consider complimentary approaches to the indirect and feasible implementation of group discussion. They argue that such strategies may overcome the barriers to direct discussion observed across a range of groups and organizations.

    2006-03-01

    Full Text Available Abstract Background The completeness of preferences is assumed as one of the axioms of expected utility theory but has been subject to little empirical study. Methods Fifteen non-health professionals was recruited and familiarised with the standard gamble technique. The group then met five times over six months and preferences were elicited independently on 41 scenarios. After individual valuation, the group discussed the scenarios, following which preferences could be changed. Changes made were described and summary measures (mean and median before and after discussion compared using paired t test and Wilcoxon Signed Rank Test. Semi-structured telephone interviews were carried out to explore attitudes to discussing preferences. These were transcribed, read by two investigators and emergent themes described. Results Sixteen changes (3.6% were made to preferences by seven (47% of the fifteen members. The difference between individual preference values before and after discussion ranged from -0.025 to 0.45. The average effect on the group mean was 0.0053. No differences before and after discussion were statistically significant. The group valued discussion highly and suggested it brought four main benefits: reassurance; improved procedural performance; increased group cohesion; satisfying curiosity. Conclusion The hypothesis that preferences are incomplete cannot be rejected for a proportion of respondents. However, brief discussion did not result in substantial number of changes to preferences and these did not have significant impact on summary values for the group, suggesting that incompleteness, if present, may not have an important effect on cost-utility analyses.

    2011-12-01

    This study aims to analyze the characteristics of discussion materials that promote student participation in discussions, satisfaction with student instruction, and tutor intervention in the medical humanities. We surveyed 117 premedical students and 7 tutors who attended 4-week group discussions in the medical humanities in 2010. We described the discussion materials using the following 4 characteristics as independent variables: material type, level of understanding, interest, and quantity. Dependent variables were: student participation in the discussion, student instruction satisfaction, and tutor intervention. Correlation analysis, multiple regression analysis, and crosstab were performed using SPSS 15.0. The correlation between the characteristics of the discussion materials differed by grade. When the books were chosen as the discussion material in the instruction of first-year premedical students, the correlation between level of understanding, interest, and quantity was negative. Higher levels of understanding of the material and interest in the material led to an increase in discussion participation among both first- and second-year premedical students. Higher levels of understanding and interest of the discussion material also increased student satisfaction with the instruction, regardless of grade. Finally, levels of understanding of the material affected the degree of tutor intervention. Tutors intervened more often in discussions with first-year premedical students than with second-year premedical students. Differences in grades and the understanding of the discussion material should be considered when choosing discussion materials. Further study is required to continue the development of the discussion model and improve methods of facilitate discussion among students in the medical humanities.

    Full Text Available The aim of this study was to examine how men who have perpetrated violence toward their partners and participated in batterer group talked about being a father and how they perceived their own fatherhood. The discussion in the group was analyzed qualitatively by using the methods of content analysis. In traditional fatherhood, they talked about avoidant, passiveness, distant, indifference, and authoritative controlling ways of acting. These men also created an image of themselves as active and caring fathers, thus including empathy and nurture in the concept of fatherhood. This new fatherhood was considered an achieved goal and an objective for the men as being a father. Talking about fatherhood in these groups is important as fatherhood and relations to children are both an important motivator toward nonviolence.

    2005-12-01

    The aim of this paper is to identify and discuss the ethical considerations that have confronted and challenged the research team when researchers facilitate conversations using private electronic mail discussion lists. The use of electronic mail group conversations, as a collaborative data generation method, remains underdeveloped in nursing. Ethical challenges associated with this approach to data generation have only begun to be considered. As receipt of ethics approval for a study titled; 'Describing transition with people who live with chronic illness' we have been challenged by many ethical dilemmas, hence we believe it is timely to share the issues that have confronted the research team. These discussions are essential so we can understand the possibilities for research interaction, communication, and collaboration made possible by advanced information technologies. Our experiences in this study have increased our awareness for ongoing ethical discussions about privacy, confidentiality, consent, accountability and openness underpinning research with human participants when generating data using an electronic mail discussion group. We describe how we work at upholding these ethical principles focusing on informed consent, participant confidentiality and privacy, the participants as threats to themselves and one another, public-private confusion, employees with access, hackers and threats from the researchers. A variety of complex issues arise during cyberspace research that can make the application of traditional ethical standards troublesome. Communication in cyberspace alters the temporal, spatial and sensory components of human interaction, thereby challenging traditional ethical definitions and calling to question some basic assumptions about identity and ones right to keep aspects of it confidential. Nurse researchers are bound by human research ethics protocols; however, the nature of research by electronic mail generates moral issues as well as ethical

    We have developed tools to explore social networks that share information in medical forums to better understand the unmet informational needs of patients and family members facing cancer treatments. We define metrics that demonstrate members discussing interleukin-2 receive a stronger response from the melanoma discussion group than a typical topic. The interleukin-2 network has a different topology than the melanoma network, has a higher density, and its members are more likely to have a higher intimacy level with another member and a lower inquisitiveness level than a typical melanoma user. Members are more likely to join the interleukin-2 network to answer a question than in the melanoma network (probability =.2 ±.05 p-value=.001). Within the melanoma network 20% of the questions posed to the community do not get an answer. In the interleukin-2 network, 1.3% of the questions (one question) do not get a response. PMID:21347134

    2013-01-01

    This paper contrasts two accounts of audience design during multiparty communication: audience design as a strategic individual-level message adjustment or as a non-strategic interaction-level message adjustment. Using a non-interactive communication task, Experiment 1 showed that people distinguish between messages designed for oneself and messages designed for another person; consistent with strategic message design, messages designed for another person/s were longer (number of words) than those designed for oneself. However, audience size did not affect message length (messages designed for different sized audiences were similar in length). Using an interactive communication task Experiment 2 showed that as group size increased so too did communicative effort (number of words exchanged between interlocutors). Consistent with a non-strategic account, as group members were added more social interaction was necessary to coordinate the group's collective situation model. Experiment 3 validates and extends the production measures used in Experiment 1 and 2 using a comprehension task. Taken together, our results indicate that audience design arises as a non-strategic outcome of social interaction during group discussion.

    Tests and final examination scores of three semesters of control students in a nursing foundation course were compared with tests and final examination scores of three semesters of participating students. Participating students were offered access to an asynchronous pretest online discussion activity with a faculty e-moderator. While the simplified Bloom's revised taxonomy assisted in creating appropriate preparatory test and final examination questions for pretest online discussion, Salmon's five-stage online method provided direction to the e-moderator on how to encourage students to achieve Bloom's higher-order thinking skills during the pretest online discussions. Statistical analysis showed the pretest online discussion activity had a generally positive impact on tests and final examination scores, when controlling for a number of possible confounding variables, including instructor, cumulative grade point average, age, and credit hours.

    Although the free-floating discussion format is widely used in group therapy, the application of this format in the context of supervisory groups has yet to be clarified. The purpose of this study was to explore the mechanisms involved in facilitating and learning the free-floating discussion format in a supervisory group. A phenomenological approach was used to investigate the group content and personal feedback of a psychiatric-nurse supervisory group. The group held on 12 sessions. Each session was conducted once weekly and lasting 150 minutes. The findings identified the functions of free-floating discussions in the context of supervisory groups as: embodied interaction and initiation by handling. Embodied interaction included: reflection on the experience of the other, sense of body, and present action. Initiation by handling included: facilitating the self-narrative, following the lead of the group, and reflecting in accordance with the group. The role of the facilitator is to parallel process rather than to lead in order to produce practical wisdom. Free-floating discussion and self-evidence from initiation by handling has the potential to promote spontaneity, creativity, and self-confidence in clinical practice and to promote deep learning.

    Full Text Available In the present article we use a chat conversations’ corpus to study the process of resolving language problems. Our corpus includes chat conversations which took place between LSP students engaged in correcting errors in their peers’ summaries. The participants worked in groups and used the Windows Messenger program for communication within the group. Their task also included making use of electronic dictionaries and other reference materials. The conversations’ corpus obtained as a result of this exercise was analyzed holistically for possible indicators of each particular stage of the problem solving process. Later these indicators were validated throughout the entire corpus. Each problem solving process was thus represented as a chain of indicators and acceptability was determined for each error correction. The resulting problem solving chains were used to prove our hypotheses concerning internal and external support in text reproduction.

  6. Effects of communication strategy training on EFL students’ performance in small-group discussions

    2013-10-01

    Full Text Available In recent years, a number of studies have been conducted with regard to communication strategy training and performance on communicative tasks (Lam, 2009; Nakatani, 2010; Naughton, 2006. This study aims to add to the literature by examining how two strategies, clarifying/confirming and extending a conversation, and two methods of teaching the strategies, affected the interactional sequences and overall group discussion performance of EFL students at a university in Japan. Pre and posttreatment small-group discussions were recorded for assessment, and a stimulated recall interview was administered to determine the participants’ perceptions of their learning and language use. Posttest results reveal that the experimental groups that were taught predetermined phrases aimed at clarifying/confirming and extending a conversation employed such phrases more frequently than the control group. However, this employment of phrases did not lead to higher gains in group discussion skills as the control group enjoyed the largest gains from pre to posttest. The researchers consider the findings in light of previous research, and conclude with recommendations for future research on the topic with special regard to research design.

  7. Qualitative findings from focus group discussions on hand hygiene compliance among health care workers in Vietnam.

    Salmon, Sharon; McLaws, Mary-Louise

    2015-10-01

    It is accepted by hospital clinical governance that every clinician's "duty of care" includes hand hygiene, yet globally, health care workers (HCWs) continue to struggle with compliance. Focus group discussions were conducted to explore HCWs' barriers to hand hygiene in Vietnam. Twelve focus group discussions were conducted with HCWs from 6 public hospitals across Hanoi, Vietnam. Discussions included participants' experiences with and perceptions concerning hand hygiene. Tape recordings were transcribed verbatim and then translated into English. Thematic analysis was conducted by 2 investigators. Expressed frustration with high workload, limited access to hand hygiene solutions, and complicated guidelines that are difficult to interpret in overcrowded settings were considered by participants to be bona fide reasons for noncompliance. No participant acknowledged hand hygiene as a duty of care practice for her or his patients. Justification for noncompliance was the observation that visitors did not perform hand hygiene. HCWs did acknowledge a personal duty of care when hand hygiene was perceived to benefit her or his own health, and then neither workload or environmental challenges influenced compliance. Limited resources in Vietnam are amplified by overcrowded conditions and dual bed occupancy. Yet without a systematic systemic duty of care to patient safety, changes to guidelines and resources might not immediately improve compliance. Thus, introducing routine hand hygiene must start with education programs focusing on duty of care. Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc.

    2002-12-01

    This qualitative study aimed to examine cultural differences in knowledge, attitudes and practices related to erectile dysfunction (ED) utilizing focus group discussion. Six focus groups consisting of 66 men, 45-70-y-old were conducted-two Malay groups (n=18), two Chinese groups (n=25) and two Indian groups (n=23). Participants were purposely recruited from the general public on a voluntary basis with informed consent. Transcripts were analyzed using qualitative data analysis software ATLASti. The Malay and Chinese traditional remedies for preventing or treating ED are commonly recognized among all races. Many have a negative perception of someone with ED. Malay and Chinese men tended to blame their wife for their problem and thought that the problem might lead to extra-marital affairs, unlike the Indian men who attributed their condition to fate. Malays would prefer traditional medicine for the problem. The Chinese felt they would be more comfortable with a male doctor whilst this is not so with the Malays or Indians. Almost all prefer the doctor to initiate discussion on sexual issues related to their medical condition. There is a need for doctors to consider cultural perspectives in a multicultural society as a lack of understanding of this often contributes to an inadequate consultation.

    Full Text Available This paper develops a version of Robust Stochastic Maximum Principle (RSMP applied to the Minimax Mayer Problem formulated for stochastic differential equations with the control-dependent diffusion term. The parametric families of first and second order adjoint stochastic processes are introduced to construct the corresponding Hamiltonian formalism. The Hamiltonian function used for the construction of the robust optimal control is shown to be equal to the Lebesque integral over a parametric set of the standard stochastic Hamiltonians corresponding to a fixed value of the uncertain parameter. The paper deals with a cost function given at finite horizon and containing the mathematical expectation of a terminal term. A terminal condition, covered by a vector function, is also considered. The optimal control strategies, adapted for available information, for the wide class of uncertain systems given by an stochastic differential equation with unknown parameters from a given compact set, are constructed. This problem belongs to the class of minimax stochastic optimization problems. The proof is based on the recent results obtained for Minimax Mayer Problem with a finite uncertainty set [14,43-45] as well as on the variation results of [53] derived for Stochastic Maximum Principle for nonlinear stochastic systems under complete information. The corresponding discussion of the obtain results concludes this study.

    This study aimed to compare the effects between group discussion and educational booklet on nursing students' attitude and practice toward patient privacy in Iran. A two-group, pre-test and post-test design study was conducted in 2015. The study was conducted on 60 nursing students in Kashan, Iran who were randomly allocated into two groups to be trained on patient privacy either through group discussion or by an educational booklet. The students' attitude and practice was assessed before and after the education using a questionnaire and a checklist. Data analysis was performed through paired t-test, Wilcoxon signed ranks test, and independent samples t-tests. Before the intervention, no significant difference was found between the group designated to group discussion and that designated to the educational booklet in the mean overall score of attitude (P=0.303) and practice (P=0.493) toward patient privacy. After the intervention, the mean attitude score significantly increased in the two groups (P=0.001). Moreover, the students' practice score increased in the discussion group while it did not significantly change in the booklet group (P=0.001). Both methods were effective on the students' attitude; however, the educational booklet did not affect their practice toward patient privacy. Group discussion can effectively improve the students' attitude and practice toward patient privacy.

    2008-03-01

    The authors investigated the effect of group discussion, such as may occur formally in panel interview scenarios, assessment centers, or 360-degree feedback situations, on judgments of performance. Research on group polarization suggests that the effect of group discussion combined with raters' preexisting impressions of ratees or interviewees should result in an extremitization of impressions. Thus, the authors hypothesized that group discussion would (a) make ratings less accurate, (b) polarize impressions that were already good or poor as reflected by greater contrast effects, and (c) increase positive halo. Results indicated that group discussion resulted in less accurate ratings and greater contrast effects. Additional analyses suggested that group discussion increased positive halo. The authors discuss implications for research on group or panel judgments.

  19. Stakeholders' Perceptions on Shortage of Healthcare Workers in Primary Healthcare in Botswana: Focus Group Discussions.

    Directory of Open Access Journals (Sweden)

    Full Text Available An adequate health workforce force is central to universal health coverage and positive public health outcomes. However many African countries have critical shortages of healthcare workers, which are worse in primary healthcare. The aim of this study was to explore the perceptions of healthcare workers, policy makers and the community on the shortage of healthcare workers in Botswana.Fifteen focus group discussions were conducted with three groups of policy makers, six groups of healthcare workers and six groups of community members in rural, urban and remote rural health districts of Botswana. All the participants were 18 years and older. Recruitment was purposive and the framework method was used to inductively analyse the data.There was a perceived shortage of healthcare workers in primary healthcare, which was believed to result from an increased need for health services, inequitable distribution of healthcare workers, migration and too few such workers being trained. Migration was mainly the result of unfavourable personal and family factors, weak and ineffective healthcare and human resources management, low salaries and inadequate incentives for rural and remote area service.Botswana has a perceived shortage of healthcare workers, which is worse in primary healthcare and rural areas, as a result of multiple complex factors. To address the scarcity the country should train adequate numbers of healthcare workers and distribute them equitably to sufficiently resourced healthcare facilities. They should be competently managed and adequately remunerated and the living conditions and rural infrastructure should also be improved.

    2017-01-01

    The equine industry in Great Britain has not been subject to the same pressures as the farming industry to engage with welfare assessment, but this may change as concern about equine welfare increases. Stakeholder attitudes toward welfare assessment may impact the implementation of welfare assessment practices. Focus-group discussions regarding welfare assessment were conducted with 6 equine stakeholder groups: leisure horse owners (caregivers; n = 4), grooms (n = 5), veterinary surgeons (n = 3), welfare scientists (n = 4), welfare charity workers (n = 5), and professional riders (n = 4). Three themes emerged from the discussions: (a) Participants predominantly interpreted welfare assessment as a means of identifying and correcting poor welfare in an immediate way; (b) participants believed that horse welfare varied over time; and (c) attributes of the assessor were viewed as an important consideration for equine welfare assessment. The views of equine industry members give insight into the value welfare assessments may have to the industry and how equine welfare assessment approaches can achieve credibility within the industry and increase the positive impact of welfare assessments on equine welfare.

    Full Text Available Introduction: The communication between faculty and students is a vital component of optimal facilitation of knowledge and learning. Various factors influence this dynamic. Aim: To assess communication levels between students and teachers in a dental college scenario via focus group discussion. Materials and Methods: The focus group discussion consisted of 10 groups; 5 groups representing the teachers, and 5 groups representing the students. Each group consisted of 6 participants. Hence there were a total of 30 teacher and 30 student participants. Focus group discussion was conducted for each of the groups for 30–45 min duration in the presence of a moderator and a note-taker. Open-ended questions were put across by the moderator to initiate and continue the discussions. The hand-written data taken by the note-taker were transcribed onto a computer on the same day of the discussion. Based on the transcription, domains were created for the student and teacher groups. Results: The issues raised by both the teacher and student groups in this focus group discussion were broadly classified into the following themes: (1 Past versus current scenario, (2 attitudes toward communication and learning, (3 hindrances to effective communication, and (4 potential solutions. Conclusions: Focus group discussion exposed many differences in the perceptions of teachers and students to communication. Each group, however, felt that bridging the teacher-student communication barrier was crucial to improve the teaching-learning experience. Many constructive solutions were provided by both the groups which can help to improve the quality of teaching-learning experience resulting in better quality of education.

  4. Insights for conducting real-time focus groups online using a web conferencing service.

    Kite, James; Phongsavan, Philayrath

    2017-01-01

    Background Online focus groups have been increasing in use over the last 2 decades, including in biomedical and health-related research. However, most of this research has made use of text-based services such as email, discussion boards, and chat rooms, which do not replicate the experience of face-to-face focus groups. Web conferencing services have the potential to more closely match the face-to-face focus group experience, including important visual and aural cues. This paper provides critical reflections on using a web conferencing service to conduct online focus groups. Methods As part of a broader study, we conducted both online and face-to-face focus groups with participants. The online groups were conducted in real-time using the web conferencing service, Blackboard Collaborate (TM). We used reflective practice to assess how the conduct and content of the groups were similar and how they differed across the two platforms. Results We found that further research using such services is warranted, particularly when working with hard-to-reach or geographically dispersed populations. The level of discussion and the quality of the data obtained was similar to that found in face-to-face groups. However, some issues remain, particularly in relation to managing technical issues experienced by participants and ensuring adequate recording quality to facilitate transcription and analysis. Conclusions Our experience with using web conferencing for online focus groups suggests that they have the potential to offer a realistic and comparable alternative to face-to-face focus groups, especially for geographically dispersed populations such as rural and remote health practitioners. Further testing of these services is warranted but researchers should carefully consider the service they use to minimise the impact of technical difficulties.

  10. Specimen charging on thin films with one conducting layer:Discussion of physical principles

    Energy Technology Data Exchange (ETDEWEB)

    Glaeser, Robert M.; Downing, Kenneth H.

    2003-04-15

    While the most familiar consequences of specimen charging in transmission electron microscopy can be eliminated by evaporating a thin conducting film (such as a carbon film) onto an insulating specimen, or by preparing samples directly on such a conducting film to begin with, a more subtle charging effect still remains. We argue here that specimen charging is in this case likely to produce a dipole sheet rather than a layer of positive charge at the surface of the specimen. A simple model of the factors that control the kinetics of specimen charging, and its neutralization, is discussed as a guide for experiments that attempt to minimize the amount of specimen charging. Believable estimates of the electrostatic forces and the electron optical disturbances that are likely to occur suggest that specimen bending and warping may have the biggest impact on degrading the image quality at high resolution. Electron optical effects are likely to be negligible except in the case of a specimen that is tilted to high angle. A model is proposed to explain how both the mechanical and electron-optical effects of forming a dipole layer would have much greater impact on the image resolution in a direction perpendicular to the tilt axis, a well-known effect in electron microscopy of two-dimensional crystals.

    This paper focuses on the factors that are likely to play a role in individual learning outcomes from group discussions, and it includes a comparison featuring test-enhanced learning. A between-groups design (N = 98) was used to examine the learning effects of feedback if provided to discussion groups, and to examine whether group discussions benefit learning when compared to test-enhanced learning over time. The results showed that feedback does not seem to have any effect if provided to a discussion group, and that test-enhanced learning leads to better learning than the discussion groups, independent of retention interval. Moreover, we examined whether memory and learning might be influenced by the participants' need for cognition (NFC). The results showed that those scoring high on NFC remembered more than those who scored low. To conclude, testing trumps discussion groups from a learning perspective, and the discussion groups were also the least beneficial learning context for those scoring low on NFC.

    Small group discussions are useful tools in medical ethics education. We aimed to assess student satisfaction with specific components of a small group discussion and to evaluate student self-assessment of the objectives of education. A structured questionnaire was developed after a literature review and a focus group interview. Components of the small group discussion were categorized by discussion case (self, other), individual activities (self-study, making materials, presentation experience), and group activities (preclass/in-class/postclass/plenary discussion, instructor's comments). The items for student self-assessment were: "To specify ethical issue in actual practice", "To get new knowledge", "To consider doctor's entity", "Empathy to others", "To get multidimensional viewpoint", "Viewpoint change", "To deliver my thought clearly", and "Ability to confront the medical ethics dilemma in the future". After the survey, an in-depth interview was performed to determine the reason behind the students' answers. A total of 121 students responded, for whom overall satisfaction and self-assessment were high. Students reported greater satisfaction with self-case, presentation experience, in-class discussion, and instructor's comments but less satisfaction with self-study before class and postclass discussion. Student self-assessment was highest in the ability to specify an ethical issue and lowest for viewpoint change and self-confidence. After multivariate analysis, higher student self-assessment was associated with greater satisfaction with the small group discussion. To improve the quality of medical ethics education, close investigation and monitoring of each component of the small group discussion and student achievement are essential, as is continuous feedback.

    Access to and use of hygienic shared sanitation facilities is fundamental in reducing the high risk of diseases such as diarrhoea and respiratory infections. We evaluated the effectiveness of group discussions and commitment in improving the cleaning behaviour of shared sanitation users in three urban slums in Kampala, Uganda. The study follows the risk, attitudes, norms, abilities and self-regulation (RANAS) model of behaviour change and some factors of the social dilemma theory. A pre-versus post-intervention survey was conducted in three slums of Kampala, Uganda, between December 2012 and September 2013. From the pre-intervention findings, users of dirty sanitation facilities were randomly assigned to discussions, discussions + commitment and control interventions. The interventions were implemented for 3 months with the aim of improving cleaning behaviour. This paper provides an analysis of 119 respondents who belonged to the intervention discussion-only (n = 38), discussions + commitment (n = 41) and the control (no intervention, n = 40) groups. Compared to the control, discussions and discussions + commitment significantly improved shared toilet users' cleaning behaviour. The rate of improvement was observed through behavioural determinants such as cleaning obligation, cleaning ease, cleaning approval and affective beliefs. Our study findings show that group discussions and commitment interventions derived from RANAS model of behaviour change are effective in improving the shared sanitation users' cleaning behaviour.

    Full Text Available Abstract Background Sexually transmitted diseases (STDs are a major public health problem among young people and can lead to the spread of HIV. Previous studies have primarily addressed barriers to STD care for symptomatic patients. The purpose of our study was to identify perceptions about existing barriers to and ideal services for STDs, especially asymptomatic screening, among young people in a southeastern community. Methods Eight focus group discussions including 53 White, African American, and Latino youth (age 14–24 were conducted. Results Perceived barriers to care included lack of knowledge of STDs and available services, cost, shame associated with seeking services, long clinic waiting times, discrimination, and urethral specimen collection methods. Perceived features of ideal STD services included locations close to familiar places, extended hours, and urine-based screening. Television was perceived as the most effective route of disseminating STD information. Conclusions Further research is warranted to evaluate improving convenience, efficiency, and privacy of existing services; adding urine-based screening and new services closer to neighborhoods; and using mass media to disseminate STD information as strategies to increase STD screening.

    2013-01-01

    To evaluate the function of Talking Mats (TM) in a discussion group for people with Huntington's disease (HD). Four persons with HD and their group leader participated. The group was videotaped during four discussions, two with and two without TM. A mixed method quantitative and qualitative study was implemented by evaluating the conversations using the protocol Effectiveness Framework of Functional Communication by analyzing the number of follow-up questions and by post discussion interviews. The results showed improved effectiveness of communication for all participants and an increased number of follow-up questions, both from the group leader and from some of the participants. All participants and the leader were positive regarding the use of TM but there were also drawbacks. TM could be useful in discussion groups for people with HD. An increased number of follow-up questions when TM is used may lead to a deeper understanding within the group. This study is the first of its kind and more research in the area is needed.

    2014-01-01

    Objectives To provide a history on nursing science within the Gynecology Oncology Group (GOG); to discuss challenges and facilitators of nursing science in the cooperative group (CG) using a current nurse-led protocol (GOG-0259) as an exemplar; and to propose recommendations aimed at advancing nursing science in the CG setting. Data Source GOG reports and protocol databases, online databases of indexed citations, and experiences from the development and implementation of GOG-0259. Conclusions Benefits of CG research include opportunities for inter-disciplinary collaboration and ability to rapidly accrue large national samples. Challenges include limited financial resources to support non-treatment trials, a cumbersome protocol approval process, and lack of experience with nursing/quality of life intervention studies. Formal structures within GOG need to be created to encourage nurse scientists to become active members; promote collaboration between experienced GOG advanced practice nurses and new nurse scientists to identify nursing research priorities; and consider innovative funding structures to support pilot intervention studies. Implications for Nursing Practice Understanding the CG research process is critical for nurse scientists. A multi-disciplinary team of CG leaders can help investigators navigate a complex research environment and can increase awareness of the value of nursing research. PMID:24559780

    2017-06-09

    Despite a body of evidence on racial/ethnic minority enrollment and retention in research, literature specifically focused on recruiting racially/ethnically diverse older adults for social science studies is limited. There is a need for more rigorous research on methodological issues and the efficacy of recruitment methods. Cultural obstacles to recruitment of racial/ethnic minority older adults include language barriers, lack of cultural sensitivity of target communities on the part of researchers, and culturally inappropriate assessment tools. Guided by the Consolidated Framework for Implementation Research (CFIR), this study critically appraised the recruitment of racial/ethnic minority older adults for focus groups. The initial approach involved using the physical and social infrastructure of the ElderSmile network, a community-based initiative to promote oral and general health and conduct health screenings in places where older adults gather, to recruit racial/ethnic minority adults for a social science component of an interdisciplinary initiative. The process involved planning a recruitment strategy, engaging the individuals involved in its implementation (opinion leaders in senior centers, program staff as implementation leaders, senior community-based colleagues as champions, and motivated center directors as change agents), executing the recruitment plan, and reflecting on the process of implementation. While the recruitment phase of the study was delayed by 6 months to allow for ongoing recruitment and filling of focus group slots, the flexibility of the recruitment plan, the expertise of the research team members, the perseverance of the recruitment staff, and the cultivation of change agents ultimately resulted in meeting the study targets for enrollment in terms of both numbers of focus group discussions (n = 24) and numbers of participants (n = 194). This study adds to the literature in two important ways. First, we leveraged the social and

    Despite concerns about online health information and efforts to improve its credibility, how users evaluate and utilize such information presented in Web sites and online discussion groups may involve different evaluative mechanisms. This study examined credibility and homophily as two underlying mechanisms for social influence with regard to online health information. An original experiment detected that homophily grounded credibility perceptions and drove the persuasive process in both Web sites and online discussion groups. The more homophilous an online health information stimulus was perceived as being, the more likely people were to adopt the advice offered in that particular piece of information.

    Doran, Frances; Hornibrook, Julie

    2013-03-01

    This paper reports on a small qualitative research study which explored women's experiences of participation in a pregnancy and postnatal group that incorporated yoga and facilitated discussion. The group is offered through a community based feminist non-government women's health Centre in Northern NSW Australia. The purpose of the research was to explore women's experiences of attending this pregnancy and postnatal group. An exploratory qualitative approach was used to explore women's experiences of attending the group. Fifteen women participated in individual, in-depth face-to-face interviews. Interviews were recorded and transcribed verbatim. Thematic analysis was undertaken to analyse the qualitative data. Six themes were developed, one with 3 subthemes. One theme was labelled as: 'the pregnancy and motherhood journey' and included 3 sub-themes which were labelled: 'preparation for birth', 'connecting with the baby' and 'sharing birth stories.' The other five themes were: 'feminine nurturing safe space', 'watching and learning the mothering', 'building mental health, well-being and connections', the "group like a rock and a seed' and 'different from mainstream'. This research adds to the overall body of knowledge about the value of yoga in pre and postnatal care. It demonstrates the value of sharing birth stories and the strong capacity women have to support one another, bringing benefits of emotional and social well-being, information, resources and support derived from group based models of care.

    Lecture is the most common teaching method used in ethics education, while problem-based learning (PBL) and small group discussion (SGD) have been introduced as more useful methods. This study compared these methods in teaching medical ethics. Twenty students (12 female and 8 male) were randomly assigned into two groups. The PBL method was used in one group, and the other group was taught using the SGD method. Twenty-five open-ended questions were used for assessment and at the end of the course, a course evaluation sheet was used to obtain the students' views about the advantages and disadvantages of each teaching method, their level of satisfaction with the course, their interest in attending the sessions, and their opinions regarding the effect of teaching ethics on students' behaviors. The mean score in the PBL group (16.04 ± 1.84) was higher than the SGD group (15.48 ± 2.01). The satisfaction rates in the two groups were 3.00 ± 0.47 and 2.78 ± 0.83 respectively. These differences were not statistically significant. Since the mean score and satisfaction rate in the PBL group were higher than the SGD group, the PBL method is recommended for ethics education whenever possible.

    - Facebook (Menlo Park, California) is one of many online sites that provide potential educational tools for pathologists. We have each founded Facebook groups dedicated to anatomic pathology, in which members can share cases, ask questions, and contribute to discussions. - To report our experiences in founding and maintaining these Facebook groups and to characterize the contributed content. - We circulated a survey among the group founders, then compiled and analyzed the responses. - The groups varied in membership and in the quality of member contribution. Most posts were of pathology cases, although other topics (such as research articles) were also shared. All groups remained active and received posts from users all over the world, although all groups had many noncontributing members and received unwanted messages (which were screened and removed). Most founders were glad they had founded the groups because they provided an opportunity to both teach and learn. - Each analyzed Facebook group had a different character, and some downsides exist, but the groups all provided a no-cost way for pathologists and others across the world to interact online with many colleagues.

    The aim of this prospective quantitative study was to compare the effect of different instructional formats on dental students' skills and knowledge acquisition for access cavity preparation. All first-year dental students were invited to participate in this study conducted during the four consecutive two-week endodontic rotation courses at the University of the Pacific Arthur A. Dugoni School of Dentistry in spring semester 2015. Four alphabetically distributed intact groups of students were randomly allocated to two groups (n=70 each) that participated in either small-group discussion or a traditional lecture on access preparation. The first outcome measure was skill acquisition, measured by the quality of access cavities prepared in extracted teeth at the conclusion of the session. Two blinded raters scored direct observations on a continuous scale. Knowledge, the second outcome measure, was scored with a multiple-choice and open-ended question test at the end of each two-week session. Data were obtained for 134 of the 140 students, for a 96% response rate. The results showed that students in the small-group discussion groups scored significantly higher than those in the lecture groups when skill performance was tested (p=8.9 × 10(-7)). However, no significant differences were found in the acquisition of knowledge between the two groups on the written test. Active student participation was significantly related to improved manual skill acquisition, but the format of the session does not seem to have had a direct influence on acquired knowledge.

    Full Text Available Introduction:There are various methods of training for medical students in different colleges. Fast knowledge transfer and maximum learning are the main goals of education. Due to the limited time and also high volume of content knowledge during residency, using the best methods of training can play an important role in enhancing the skills of residents. In the current study, small group discussion as a teaching method was compared with the traditional method. Methods:In this cohort study, two groups of residents that had finished a 4-year course of orthopedic residency training programs in Tabriz and Urmia universities of medical sciences was being examined. They were divided in two groups. In order to compare the impact of the training on residents, it was compared with the result of the State Board standardized exam. The number of residents passing the written test and the Objective Structural Clinical Examination (OSCE per year have been identified and compared with the groups under investigation. Results:Fifty-one residents, including 4 women (7.8% and 47 men (92.2%, were studied for this purpose. Success rate for the small group discussion in the written exam was 59.2% and in the OSCE was 24% (95% CI. On the other hand, the success rates for the group who were trained in the traditional way were 37% and 16.6% in the written exam and OSCE, respectively. In both cases the differences were significant. Conclusion:The small group discussion method is an effective method in residency training in surgical fields that increases medical students’ learning abilities compared to traditional methods of education.

    2010-05-01

    This article is based on a critical ethnography about HIV and gender-based issues of power and violence conducted in Malawi in 2008. In all, 72 women living with HIV were recruited from four antiretroviral treatment clinics, three rural and one urban, to participate in 12 focus groups. Informed by a postcolonial feminist perspective, we analyze the process and products of these focus groups to interrogate their capacity to facilitate collective engagement with the social and structural realities confronting women in a resource-limited, highly AIDS-affected country. We present exemplars to show how women together created collective narratives to mobilize individuals to action. Findings indicate that focus groups can be used innovatively to benefit both the research and the participants, not only as a critical method of inquiry with marginalized groups but also as a forum in which validating dialogue, mutual support, and exchange of strategic information can generate transformative change to improve women's lives.

    Many online support groups are available for patients with rare disorders, but scant evidence is available on how effectively such groups provide useful information or valuable psychosocial support to their participants. It is also unclear to what extent physicians and researchers may learn more about these disorders by participating in such groups. To formally assess the utility of the Kovler Monogenic Diabetes Registry online discussion group for patients and families affected by KATP channel-related monogenic neonatal diabetes in providing psychosocial and informational support and in identifying concerns unique to patients with this rare form of diabetes. We qualitatively analyzed all 1,410 messages from the online group that consisted of 64 participants affected by KATP channel monogenic diabetes and 11 researchers. We utilized the Social Behavior Support Code to assign each message to a support category and deductive thematic analysis to identify discussion topics addressed by each message. 44% of messages provided/requested informational support, whereas 31.4% of the messages contained psychosocial/emotional support. The most popular topics of postings to the forums were diabetes treatment (503 messages) and neurodevelopmental concerns (472 messages). Participation in the discussion led researchers to modify survey instruments and design new studies focusing on specific topics of concern, such as sleep. We demonstrate that an online support group for a monogenic form of diabetes is an effective informational tool that also provides psychosocial support. Participation by researchers and care providers can inform future research directions and highlight issues of patient concern. Copyright © 2015 Elsevier Inc. All rights reserved.

    College or university is a critical period regarding unhealthy changes in eating behaviours in students. Therefore, the purpose of this study was to explore which factors influence Belgian (European) university students' eating behaviour, using a qualitative research design. Furthermore, we aimed to collect ideas and recommendations in order to facilitate the development of effective and tailored intervention programs aiming to improve healthy eating behaviours in university students. Using a semi-structured question guide, five focus group discussions have been conducted consisting of 14 male and 21 female university students from a variety of study disciplines, with a mean age of 20.6 ± 1.7 yrs. Using Nvivo9, an inductive thematic approach was used for data analysis. After the transition from secondary school to university, when independency increases, students are continuously challenged to make healthful food choices. Students reported to be influenced by individual factors (e.g. taste preferences, self-discipline, time and convenience), their social networks (e.g. (lack of) parental control, friends and peers), physical environment (e.g. availability and accessibility, appeal and prices of food products), and macro environment (e.g. media and advertising). Furthermore, the relationships between determinants and university students' eating behaviour seemed to be moderated by university characteristics, such as residency, student societies, university lifestyle and exams. Recommendations for university administrators and researchers include providing information and advice to enhance healthy food choices and preparation (e.g. via social media), enhancing self-discipline and self-control, developing time management skills, enhancing social support, and modifying the subjective as well as the objective campus food environment by e.g. making healthy foods price-beneficial and by providing vending machines with more healthy products.

  7. Making Space to Sensemake: Epistemic Distancing in Small Group Physics Discussions

    CERN Document Server

    Conlin, Luke D

    2015-01-01

    Students in inquiry science classrooms face an essential tension between sharing new ideas and critically evaluating those ideas. Both sides of this tension pose affective risks that can discourage further discussion, such as the embarrassment of having an idea rejected. This paper presents a close discourse analysis of three groups of undergraduate physics students in their first discussions of the semester, detailing how they navigate these tensions to create a safe space to make sense of physics together. A central finding is that students and instructors alike rely on a common discursive resource, epistemic distancing, to protect affect while beginning to engage with ideas in productive ways. The groups differ in how soon, how often, and how deeply they engage in figuring out mechanisms together, and these differences can be explained, in part, by differences in how they epistemically distance themselves from their claims. Implications for research include the importance of considering the coupled dynamic...

  8. Traditional male circumcision in Uganda: a qualitative focus group discussion analysis.

    Directory of Open Access Journals (Sweden)

    Amir Sabet Sarvestani

    Full Text Available BACKGROUND: The growing body of evidence attesting to the effectiveness of clinical male circumcision in the prevention of HIV/AIDS transmission is prompting the majority of sub-Saharan African governments to move towards the adoption of voluntary medical male circumcision (VMMC. Even though it is recommended to consider collaboration with traditional male circumcision (TMC providers when planning for VMMC, there is limited knowledge available about the TMC landscape and traditional beliefs. METHODOLOGY AND MAIN FINDINGS: During 2010-11 over 25 focus group discussions (FGDs were held with clan leaders, traditional cutters, and their assistants to understand the practice of TMC in four ethnic groups in Uganda. Cultural significance and cost were among the primary reasons cited for preferring TMC over VMMC. Ethnic groups in western Uganda circumcised boys at younger ages and encountered lower rates of TMC related adverse events compared to ethnic groups in eastern Uganda. Cutting styles and post-cut care also differed among the four groups. The use of a single razor blade per candidate instead of the traditional knife was identified as an important and recent change. Participants in the focus groups expressed interest in learning about methods to reduce adverse events. CONCLUSION: This work reaffirmed the strong cultural significance of TMC within Ugandan ethnic groups. Outcomes suggest that there is an opportunity to evaluate the involvement of local communities that still perform TMC in the national VMMC roll-out plan by devising safer, more effective procedures through innovative approaches.

    Full Text Available This paper reports on a case study of the use of Facebook in learning and teaching in higher education. Facebook was used as a venue for online discussion to support the existing Learning Management System (in this case Blackboard in the unit Internet Collaboration and Organisation as part of the Internet Communications degree taught fully online through Open Universities Australia (OUA. Students’ posts to both Facebook and the Blackboard discussion forum were analysed for content, length, and when throughout the study period they were posted. This is significant as much of the previous work in this area has relied on students self-reporting, rather than direct observation of student behaviour. These results were then compared to earlier instances of the same unit that ran within the previous twelve months, one fully online with OUA only using the Blackboard discussion group, and a second taught at Curtin University with both blended learning for students at the University’s Bentley campus as well as fully online for external students, that utilised both Blackboard and Facebook. The results show that Facebook greatly increases the level of student activity in online discussions, both absolutely and in the level of sustained activity across the unit’s study period. Facebook groups also had a different pattern of content from Blackboard. In Blackboard discussion is more focused on the set unit learning content, in Facebook students were using the groups to discuss administration and assignments and also bring in additional material from outside the units set learning materials. Facebook posts, while more sustained over the semester, were shorter in length. This study found that the addition of a Facebook discussion forum does not noticeably impact on the use of Blackboard’s discussion forum, but rather adds a new dimension to the mix of online interaction. The paper concludes that there is value in using both of these forums for student

    To assess sickle cell disease (SCD) patient and carer perspectives on the primary care services related to SCD that they receive from their general practitioner (GP). A focus group discussion was used to elicit the views of patients about the quality of care they receive from their primary health-care providers and what they thought was the role of primary care in SCD management. The focus group discussion was video recorded. The recording was then examined by the project team and recurring themes were identified. A comparison was made with notes made by two scribes also present at the discussion. Sickle Cell Society in Brent, UK. Ten participants with SCD or caring for someone with SCD from Northwest London, UK. Patients' perceptions about the primary care services they received, and a list of key themes and suggestions. Patients and carers often bypassed GPs for acute problems but felt that GPs had an important role to play around repeat prescriptions and general health care. These service users believed SCD is often ignored and deemed unimportant by GPs. Participants wanted the health service to support primary health-care providers to improve their knowledge and understanding of SCD. Key themes and suggestions from this focus group have been used to help develop an educational intervention for general practice services that will be used to improve SCD management in primary care.

    This article sets out to establish the naturalistic study of online social communication as a substantive topic in social psychology and to discuss the challenges of developing methods for a formal analysis of the structural and interactional features of message threads on discussion forums. I begin by outlining the essential features of online communication and specifically discussion forum data, and the important ways in which they depart from spoken conversation. I describe the handful of attempts to devise systematic analytic techniques for adapting methods such as conversation and discourse analysis to the study of online discussion. I then present a case study of a thread from the popular UK parenting forum Mumsnet which presents a number of challenges for existing methods, and examine some of the interactive phenomena typical of forums. Finally, I consider ways in which membership categorization analysis and social identity theory can complement one another in the exploration of both group processes and the rhetorical deployment of identities as dynamic phenomena in online discussion.

    As part of research investigating the complexities of managing fertility in Australia, public opinions about how Australians manage their fertility were sought from women and men. To identify public opinion about sexual and reproductive health in Australia. To ensure access to a diverse group of people throughout Australia, an online group was advertised and convened on Facebook from October through December 2013. In a closed-group moderated discussion, participants responded to questions about how people in Australia attempt to manage three aspects of fertility: avoiding pregnancy, achieving pregnancy, and difficulties conceiving. Nonidentifiable demographic information was sought; no personal accounts of fertility management were requested. The discussion transcript was analyzed thematically. There were 61 female and 2 male Facebook users aged 18 to 50 years living in Australia participating in the study. Four main themes about fertility management were identified: access, geographical location, knowledge, and cost. Participants reported that young people and people from rural areas face barriers accessing contraception and fertility services. Limited knowledge about sex and reproduction and the cost of fertility services and contraception were also said to impede effective fertility management. Reasons for inequalities in effective fertility management that are amenable to change were identified. Facebook is an effective method for gaining insights into public opinion about sexual and reproductive health.

    Clinical teaching has moved from the bedside to conference rooms; many reasons are described for this shift. Yet, essential clinical skills, professionalism, and humanistic patient interactions are best taught at the bedside. Clinical teaching has moved from the bedside to conference rooms; many reasons are described for this decline. This study explored perceptions of teachers and learners on the value of bedside teaching and the humanistic dimensions of bedside interactions that make it imperative to shift clinical teaching back to the bedside. Focus group methodology was used to explore teacher and learner opinions. Four teacher groups consisted of (a) Chief Residents, (b) Residency Program Directors, (c) skilled bedside teachers, and (d) a convenience group of other Department of Medicine faculty at Boston University School of Medicine. Six learner groups consisted 2 each of 3rd-year students, PGY1 medicine residents, and PGY2 medicine residents. Each discussion lasted 60 to 90 minutes. Sessions were audiotaped, transcribed, and analyzed using qualitative methods. Teachers and learners shared several opinions on bedside teaching, particularly around humanistic aspects of bedside interactions. The key themes that emerged included (a) patient involvement in discussions, (b) teachers as role models of humanism, (c) preserving learner autonomy, (d) direct observation and feedback of learners at the bedside, (e) interactions with challenging patients, and (e) admitting limitations. Within these themes, participants noted some behaviors best avoided at the bedside. Teachers and learners regard the bedside as a valuable venue in which to learn core values of medicine. They proposed many strategies to preserve these humanistic values and improve bedside teaching. These strategies are essential for true patient-centered care.

    Online social networking is increasingly being used among medical practitioners. However, few studies have evaluated its use in therapeutic endoscopy. Here, we aimed to analyze the shared topics and activities of a group of endoscopic retrograde cholangiopancreatography (ERCP) doctors in a social networking-based endoscopic retrograde cholangiopancreatography discussion group (EDG). Six ERCP trainers working in Xijing Hospital and 48 graduated endoscopists who had finished ERCP training in the same hospital were invited to join in EDG. All group members were informed not to divulge any private information of patients when using EDG. The activities of group members on EDG were retrospectively extracted. The individual data of the graduated endoscopists were collected by a questionnaire. From June 2014 to May 2015, 6924 messages were posted on EDG, half of which were ERCP related. In total, 214 ERCP-related topics were shared, which could be categorized into three types: sharing experience/cases (52.3%), asking questions (38.3%), and sharing literatures/advances (9.3%). Among the 48 graduated endoscopists, 21 had a low case volume of less than 50 per year and 27 had a high volume case volume of 50 or more. High-volume graduated endoscopists posted more ERCP-related messages (P=0.008) and shared more discussion topics (P=0.003) compared with low-volume graduated endoscopists. A survey showed that EDG was useful for graduated endoscopists in ERCP performance and management of post-ERCP complications, etc. A wide range of ERCP-related topics were shared on the social networking-based EDG. The ERCP-related behaviors on EDG were more active in graduated endoscopists with an ERCP case volume of more than 50 per year.

    Background The importance of long term rehabilitation for people with stroke is increasingly evident, yet it is not known whether such services can be materialised in countries with limited community resources. In this study, we explored the perception of rehabilitation professionals and people with stroke towards long term stroke rehabilitation services and potential approaches to enable provision of these services. Views from providers and users are important in ensuring whatever strategies developed for long term stroke rehabilitations are feasible and acceptable. Methods Focus group discussions were conducted involving 15 rehabilitation professionals and eight long term stroke survivors. All recorded conversations were transcribed verbatim and analysed using the principles of qualitative research. Results Both groups agreed that people with stroke may benefit from more rehabilitation compared to the amount of rehabilitation services presently provided. Views regarding the unavailability of long term rehabilitation services due to multi-factorial barriers were recognised. The groups also highlighted the urgent need for the establishment of community-based stroke rehabilitation centres. Family-assisted home therapy was viewed as a potential approach to continued rehabilitation for long term stroke survivors, given careful planning to overcome several family-related issues. Conclusions Barriers to the provision of long term stroke rehabilitation services are multi-factorial. Establishment of community-based stroke rehabilitation centres and training family members to conduct home-based therapy are two potential strategies to enable the continuation of rehabilitation for long term stroke survivors.

    The aim of English teaching is not only to make the students learn new words and grammar, answer multiple- choice questions to get good scores, but also to enhance the students’abilities of the integrated application of English, speaking and listen⁃ing in particular. The ultimate goal of learning English is to use English to communicate with others in the future jobs and real life. However, the non-English majors have great trouble speaking English in class and in real life. Such ways as Socratic dialogues, cause analysis and questionnaire are used to investigate the reasons. In order to improve speaking ability, group discussion is used in class. In consequence, the students have more interest, motivation, courage and confidence in speaking English. Meanwhile, they have also established the concept of using what they learned in class, in practical work and real life.

    To assess adolescents' perceptions about factors influencing their food choices and eating behaviors. Data were collected in focus-group discussions. The study population included 141 adolescents in 7th and 10th grade from 2 urban schools in St Paul, Minn, who participated in 21 focus groups. Data were analyzed using qualitative research methodology, specifically, the constant comparative method. Factors perceived as influencing food choices included hunger and food cravings, appeal of food, time considerations of adolescents and parents, convenience of food, food availability, parental influence on eating behaviors (including the culture or religion of the family), benefits of foods (including health), situation-specific factors, mood, body image, habit, cost, media, and vegetarian beliefs. Major barriers to eating more fruits, vegetables, and dairy products and eating fewer high-fat foods included a lack of sense of urgency about personal health in relation to other concerns, and taste preferences for other foods. Suggestions for helping adolescents eat a more healthful diet include making healthful food taste and look better, limiting the availability of unhealthful options, making healthful food more available and convenient, teaching children good eating habits at an early age, and changing social norms to make it "cool" to eat healthfully. The findings suggest that if programs to improve adolescent nutrition are to be effective, they need to address a broad range of factors, in particular environmental factors (e.g., the increased availability and promotion of appealing, convenient foods within homes schools, and restaurants).

  4. Teacher Identity and the Marketizised Society. Discursive Constructions in Teachers’ Discussion Groups

    Full Text Available In the latest decennium, there have been several and gradual changes in the Swedish and other European school systems. The steering system has become more decentralized and the entire school system is now a part of the freedom of trade. Schools are competing with each other and this has, according to previous research, an effect on how teachers think about, and carry out their everyday activities (Gerwitz et al. 1995; Irisdotter 2006. How teachers think about themselves, their students and the educational task is of great importance for the social climate of the classroom and, in the longer run, society in general. The current study dicusses how teachers‘ identities and self-understandings are influenced by the marketization of society. The material analysed consists of group discussions in three different teacher groups in compulsory school in Sweden. Questions raised are: Can teachers work within the context of marketization and yet relate to it with an attitude of self-awareness and critical reflection? And how can teachers deal with both traditional teacher values and progressive, democratic values that may be in conflict with the conditions of a marketizised school system?

    The inappropriate translation of scientific information of geohazard (volcanic, landslide and crater lake outgassing) risks to any local population leaves people with incongruent views of the real dangers. Initial workshops organized under the supervision of the VLIR-OI (Flemish Interuniversity Council - Own Initiatives) members have led to the deployment of billboards as requested and drawn up by the locals. The VLIR-OI project has also organized focus group discussions (FGD) with the local stakeholders to find out in various cities, the state of preparedness, the response to emergency situations, the recovery from the emergency and the mitigation. Researchers have preferred open discussion with the local population and its representatives in order to elicit information that otherwise might not be found on a structured questionnaire. FGD provide a meaningful interactive opportunity to collect information and reflection on a wide range of input. The method provides an insight into problems that require a solution through a process of discovering the meaning attributed to certain events or issues. In this research four cardinal points as preparedness, response, recovery and mitigation (Fothergill, 1996) guided the FGD. The population (i.e. local town councils) were constituted by a mix of chiefs, engineers, technicians and civil servants and government officials. In all the three city councils concerned, the engineers in charge complained about the lack of strategic planning, and about the missing of an elaborated strategy for disasters. They are aware of the existence of an organigram in the "Département de l'Action Civile" in Yaounde but never received any "strategic" document. Therefore inappropriate actions might be taken by the municipalities themselves. Fortunately all people interrogated at the FDG always mentioned solidarity in any event.

    The endorsement of the chain of survival concept and early defibrillation has challenged health professionals to reconsider their beliefs about how they respond to in-hospital resuscitation. In the rural context, where 24 hour coverage is not available nurse-initiated defibrillation is expected. Despite literature and policy change in Australia to allow nurses to initiate defibrillation, there is no current research that uses a systemic theoretical approach to investigate the specific beliefs of nurses and their use of defibrillators. The purpose of this study was to elicit a beginning understanding of the defibrillation beliefs of rural nurses. This research used focus groups within the framework of the Theory of Planned Behavior to describe the defibrillation beliefs of rural registered nurses. The sites selected for this study were two acute care hospitals in rural Australia (RRMA Classification). Each of these hospitals was in located 'other rural areas' (RRMA Classification) in separate towns and had 25 and 30 beds. The study sample consisted of 10 females and two males. Focus group questions were designed to elicit salient beliefs within the theoretical framework. Three constructs of behavioral, normative and control beliefs guided the development of the question and analysis of the discussions. In accordance with the authors of the theoretical framework, content analysis was used to analyse the data from the study. Two behavioral beliefs, four control beliefs and four normative belief categories were elicited. Two behavioral beliefs categories emerged from the open-ended question: 'What, if any are the advantages of you being able to use a defibrillator?' Participants were congruent when discussing the advantages of nurses initiating defibrillation. The two categories were 'quicker response times' (15 responses) and 'increased success with resuscitation' (8 responses). Participants were asked to identify any events that might influence their decision to use

    In May 2012, the Committee of Health and Medicinal Products issued a concept paper on the need to review the points to consider document on multiplicity issues in clinical trials. In preparation for the release of the updated guidance document, Statisticians in the Pharmaceutical Industry held a one-day expert group meeting in January 2013. Topics debated included multiplicity and the drug development process, the usefulness and limitations of newly developed strategies to deal with multiplicity, multiplicity issues arising from interim decisions and multiregional development, and the need for simultaneous confidence intervals (CIs) corresponding to multiple test procedures. A clear message from the meeting was that multiplicity adjustments need to be considered when the intention is to make a formal statement about efficacy or safety based on hypothesis tests. Statisticians have a key role when designing studies to assess what adjustment really means in the context of the research being conducted. More thought during the planning phase needs to be given to multiplicity adjustments for secondary endpoints given these are increasing in importance in differentiating products in the market place. No consensus was reached on the role of simultaneous CIs in the context of superiority trials. It was argued that unadjusted intervals should be employed as the primary purpose of the intervals is estimation, while the purpose of hypothesis testing is to formally establish an effect. The opposing view was that CIs should correspond to the test decision whenever possible. Copyright © 2013 John Wiley & Sons, Ltd.

  10. Images of Environmental Management: Competing Metaphors in Focus Group Discussions of Swedish Environmental Quality Objectives

    Science.gov (United States)

    Wibeck, Victoria

    2012-04-01

    In managing environmental problems, several countries have chosen the management by objectives (MBO) approach. This paper investigates how focus group participants from the Swedish environmental administration used metaphors to describe the mode of organization needed to attain environmental objectives. Such analysis can shed light on how an MBO system is perceived by actors and how it works in practice. Although the Swedish government intended to stimulate broad-based cooperation among many actors, participants often saw themselves as located at a certain "level," i.e., "higher" or "lower," in the MBO system—that is, their conceptions corresponded to a traditional, hierarchical interpretation of MBO. Prepositions such as "in" and "out" contributed to feelings of inclusion and exclusion on the part of MBO actors. However, horizontal metaphors merged with vertical ones, indicating ongoing competition for the right to interpret how the system of environmental objectives should best be managed. The paper concludes that any organization applying MBO could benefit from discussing alternate ways of talking and thinking about its constituent "levels."

    We adopted peer evaluation (mutual evaluation between students) for small group discussion (SGD) among first graders. The peer evaluation criteria were 5 grade scales for 5 fields: "preparation," "remark," "listening," "activeness," and "role." A comparison with tutor evaluation clarified the validity of peer evaluation for summative evaluation. Although the average of peer evaluation (4.2 (4.0-4.4)) was higher than that of tutor evaluation (3.8 (3.7-4.1)) (p=0.0601, Mann-Whitney U test), the value of the correlation coefficient between peer evaluation and summative evaluation of SGD (average 0.35 (0.12-0.54)) was almost the same as that of the coefficient between tutor evaluation and summative evaluation of SGD (average 0.36 (0.24-0.42)) (p=0.6761, Mann-Whitney U test). Principal component analysis showed that the tutor could not evaluate "remark" and "listening" independently, while students evaluate "listening" independently from other evaluation criteria. The combination of peer and tutor evaluation may be multilateral evaluation for SGD. The questionnaire about peer evaluation for students showed that they recognized the value of peer evaluation and favorably accepted its use.

    Full Text Available Using a mixed methods design, the present study attempted to identify the factors influencing Iranian untrained EFL raters in rating group oral discussion tasks. To fulfil this aim, 16 language learners of varying proficiency levels were selected and randomly assigned to groups of four and performed a group discussion task. Thirty two untrained raters were also selected based on their volunteer participations. They listened to the audio files of the group discussions and assigned a score of one to six to each language learners based on their own judgments. They also provided comments on each language learners’ performance pointing to why they assigned such scores. The researchers had an interview with the raters after the rating session as well. The quantitative phase investigated whether linguistic features of accuracy, fluency, complexity and amount of talk were attended to by the raters in terms of having any relationship to the scores the raters assigned. Speech rate as an index of fluency and amount of talk turned out to be significantly correlated with the scores. Of more importance was the qualitative phase with the aim of identifying other factors that may account for the scores. The comments provided by the raters on each score and the interviews were codified based on Content Analysis (CA approach. It was found that the raters attend not only to the linguistic features in rating oral group discussions, but they are also sensitive to the interactional features like the roles the participants take in groups tasks and the overall interaction patterns of the groups. The findings of this study may shed light on group oral assessment in terms of training the raters rating group oral tests and developing rating scales specific for group oral assessment. Persian Abstract:پژوهش حاضر، با بهره گیری از روش تحقیق ترکیبی به بررسی عوامل مؤثر بر ارزیابان آموزش ندیده

    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.

    Full Text Available This article reports the findings of a study which examined how student teachers could be empowered as more reflective practitioners through journal keeping and blog group discussions. It was carried out with six student teachers who developed their practicum over six months. Data were collected through journals, blogs, metaphors, conferences and a questionnaire. The results demonstrated that student teachers enriched their perceptions about what reflective teaching implied. Furthermore, journal keeping was approached as an informed process by virtue of which student- teachers could go beyond the descriptive documentation of what happened in their classes. Their journal entries also revealed reflective references, most of which were mainly focused on evaluating teaching, diagnosing and solving problems. Este artículo reporta los resultados de un estudio que examinó cómo se podía potenciar los practicantes como docentes más reflexivos a través del uso de diarios y discusiones mediante blogs. En el estudio participaron seis practicantes, quienes desarrollaron sus prácticas durante seis meses. Los datos se recogieron a través de diarios, blogs, metáforas, conferencias y cuestionarios. Los resultados demostraron que los practicantes enriquecieron sus percepciones acerca de lo que significa la enseñanza reflexiva. Por otra parte, el diligenciamiento del diario, el cual se hizo como un proceso informado, les permitió ir más allá de una etapa descriptiva y enfocarse en la evaluación del proceso de enseñanza, la identificación y solución de los problemas que surgieron en la clase.

    Using patient advisory groups can affect practice changes and create a patient-centric focus for a primary care practice. A successful patient advisory group has been developed for our primary care clinics. Utilizing this group, we have implemented practice improvement changes that have had a significant impact in patient care. This will be demonstrated in a case presentation involving the implementation of depression care managers at our practice sites. We will review key "best practices," as defined by the group, regarding size, composition, and meeting frequency that can be used for the development of a clinical patient advisory group.

    The acquirement of basic knowledge of clinical trials and professional attitude in their practices is a general instructional objective in the Model Core Curriculum for Pharmaceutical Education. Unfortunately, the previous program of clinical trial education was not effective in the acquirement of a professional attitude in their practices. Then, we developed the new clinical trial education program using protocol through small group discussion (SGD) and roll-playing. Our program consists of 7 steps of practical training. In step 1, the students find some problems after presentation of the protocol including case and prescription. In step 2, they analyse the extracted problems and share the information obtained in SGD. In steps 3 and 5, five clinical case scenarios are presented to the students and they discuss which case is suitable for entry to the clinical trial or which case corresponds to the discontinuance criteria in the present designed protocol. In steps 4 and 6, the roll-playing is performed by teachers and students as doctors and clinical research coordinators (CRC) respectively. Further, we conducted a trial practice based on this program for the students. In the student's self-evaluation into five grades, the average score of the skill acquisition level in each step was 3.8-4.7 grade. Our clinical trial education program could be effective in educating the candidates for CRC or clinical pharmacists.

  3. Effect of functional groups on thermal conductivity of graphene/paraffin nanocomposite

    In this paper, thermal conductivity of graphene/paraffin nanocomposite using micromechanical model has been studied. The behavior of thermal conductivity of nanocomposite as a function of volume fraction of graphene is studied. Then is shown that as the interfacial thermal resistance at the graphene–paraffin interface decreases, the thermal conductivity of nanocomposite increases. In order to reduce the interfacial thermal resistance, functional groups in the interface between graphene and paraffin are used. It can be observed that using functional groups of hydrogen, methyl and phenyl in the interface of nanocomposite, contributes to the improvement of the thermal conductivity. Moreover, as the rate of coverage of the surface of graphene with functional groups of H, CH{sub 3} and C{sub 6}H{sub 5} increases, the thermal conductivity of nanocomposite improves. - Highlights: • Thermal conductivity nanocomposite exhibit nonlinear behavior with volume faction. • Phenyl is better to form the thermal conductivity network in paraffin. • The thickness of interfacial layer can be obtained 12.75 nm.

The blending systems of polysiloxane containing propylene carbonate group with different lithium polymeric salts were studied by ion conductivity, XPS and DSC. Different lithium polymeric salts in the blending system lead to conductivity arranged in the following sequence:poly(lithium ethylenebenzene sulfonate methylsiloxane) > poly(lithium propionate methylsiloxane) > poly(lithium propylsulfonate methylsiloxane) > poly(lithium styrenesulfonate).In the blending system the best single ion conductivity was close to 10-5 Scm-1 at room temperature. XPS showed that at low lithium salt concentration the conductivity increased with the increasing content of lithium salt, in consequence of the increase of free ion and solvent separated ion pair. At high lithium salt concentration the free ion was absent and the solvent-separated ion pair functioned as carrier.

    The evidence of suicide prevention training for nurses is scarce. Strategies to enhance general nurses' ability in suicide risk assessment are critical to develop effective training programs in general medical settings. This study was aimed to examine the effectiveness of an interactive discussion group in a suicide prevention training program for general nurses. In this randomized study with two groups of pre-post study design, the sample was recruited from the Medical, Surgical, and Emergency/Intensive Care Sectors of a 2000-bed general hospital via stratified randomization. Among the 111 nurses, 57 participants randomly assigned to the control group received a two-hour baseline suicide gatekeeper lecture, and 54 participants assigning to the experimental group received an additional five-hour group discussion about suicide risk assessment skills. Using a case vignette, the nurses discussed and assessed suicide risk factors specified in a 10-item Chinese SAD PERSONS Scale during a group discussion intervention. The findings revealed that the nurses achieved significant and consistent improvements of risk identification and assessment after the intervention without influencing their mental health status for assessing suicide risks. The result suggested an effective approach of interactive group discussion for facilitating critical thinking and learning suicide risk assessment skills among general nurses.

    Graduate medical students often get less opportunity for clarifying their doubts and to reinforce their concepts after lecture classes. The Medical Council of India (MCI) encourages group discussions among students. We evaluated the effect of identifying mistakes in a given set of wrong statements and their correction by a small group discussion by graduate medical students as a revision exercise. At the end of a module, a pre-test consisting of multiple-choice questions (MCQs) was conducted. Later, a set of incorrect statements related to the topic was given to the students and they were asked to identify the mistakes and correct them in a small group discussion. The effects on low, medium and high achievers were evaluated by a post-test and delayed post-tests with the same set of MCQs. The mean post-test marks were significantly higher among all the three groups compared to the pre-test marks. The gain from the small group discussion was equal among low, medium and high achievers. The gain from the exercise was retained among low, medium and high achievers after 15 days. Identification of mistakes in statements and their correction by a small group discussion is an effective, but unconventional revision exercise in biochemistry. Copyright 2014, NMJI.

    Full Text Available Abstract Background Conventional systematic review techniques have limitations when the aim of a review is to construct a critical analysis of a complex body of literature. This article offers a reflexive account of an attempt to conduct an interpretive review of the literature on access to healthcare by vulnerable groups in the UK Methods This project involved the development and use of the method of Critical Interpretive Synthesis (CIS. This approach is sensitised to the processes of conventional systematic review methodology and draws on recent advances in methods for interpretive synthesis. Results Many analyses of equity of access have rested on measures of utilisation of health services, but these are problematic both methodologically and conceptually. A more useful means of understanding access is offered by the synthetic construct of candidacy. Candidacy describes how people's eligibility for healthcare is determined between themselves and health services. It is a continually negotiated property of individuals, subject to multiple influences arising both from people and their social contexts and from macro-level influences on allocation of resources and configuration of services. Health services are continually constituting and seeking to define the appropriate objects of medical attention and intervention, while at the same time people are engaged in constituting and defining what they understand to be the appropriate objects of medical attention and intervention. Access represents a dynamic interplay between these simultaneous, iterative and mutually reinforcing processes. By attending to how vulnerabilities arise in relation to candidacy, the phenomenon of access can be better understood, and more appropriate recommendations made for policy, practice and future research. Discussion By innovating with existing methods for interpretive synthesis, it was possible to produce not only new methods for conducting what we have termed critical

    Full Text Available The main concern of most researchers in the field of second and foreign language teaching is lessening the problems and eliminating the hinders on the way of learning a language. Writing is considered as one of the most challenging and complicated tasks for learners to perform particularly when they have to write in a second or foreign language. Numerous studies were done on the importance of the pre-writing stage and activities which are directly and indirectly related to the theme of the writing. Accordingly, the main aim of this study was to examine the effects of group discussion as a pre- activity task on writing ability. To this aim, 27 Iranian EFL learners, who were at the same level –intermediate- studying at Shokuh and Safir Institutes, Birjand, Iran were chosen randomly. Two groups- one control and one experimental group- were studied. In control group the conventional method was used in teaching writing, while in experimental group, group discussion pre-activity task was administered. After 16 sessions, the obtained data of the pretests and posttests was analyzed by SPSS software. According to the results, researcher strongly concluded that group discussion has no significant effect on writing ability of Iranian intermediate learners. This study can help teachers and syllabus designers in choosing and applying an effective pre-activity task. Keywords: writing ability, pre-activity task, group discussion, EFL learners

    College or university is a critical period regarding unhealthy changes in energy related behaviours in students. The first objective of this explorative study was to identify determinants of physical activity and sedentary behaviour in Belgian university students. Secondly, we aimed to collect ideas and recommendations to increase physical activity and decrease sedentary behaviours in university students. Using a semi-structured question guide, seven focus group discussions were conducted consisting of 17 male and 29 female university students from a variety of study disciplines, with a mean age of 20.7 ± 1.6 yrs. Using Nvivo9, an inductive thematic approach was used for data analysis. Students reported that both physical and sedentary activities were influenced by individual factors (e.g. perceived enjoyment, self-discipline, time and convenience), their social networks (e.g. (lack of) parental control, modelling, social support), physical environment (e.g. availability and accessibility, travel time/distance, prices), and macro environment (e.g. media and advertising). Furthermore, the relationships between determinants and university students' physical activity and sedentary behaviour seemed to be moderated by university characteristics, such as residency, university lifestyle, exams and academic pressure. Recommendations for future physical activity interventions include improving information strategies regarding on-campus sports activities, cheaper and/or more flexible sports subscriptions and formulas, including 'sports time' into the curricula, and providing university bicycles around campus. Students also believed that increasing students' physical activity might decrease their sedentary behaviour at the same time. The recommendations and ideas discussed in this study may facilitate the development of effective and tailored (multilevel) intervention programs aiming to increase physical activity and decrease sedentary behaviours in university students.

    2005-01-01

    Conducting group psychotherapy in a situation of intractable conflict such as Northern Ireland activates turbulent emotional dilemmas within psychotherapists and group members alike. Professional practice and therapeutic zeal must struggle daily to survive the stark encounter with the reality of a regressive and primitive psychology and on occasion may succumb to atavistic tendencies, dragging relationships down to primitive levels and leaving connections broken. In this article, three group therapists describe their countertransference struggles when leading such groups. They meet in a psychosocial setting in which the risk to one's psyche parallels the risk to one's life and limb. The countertransference experienced here is dark, indeed identified by one author as not unlike Dante's Inferno. They describe how understanding their personal countertransference enables them to survive emotionally even though it may not always lead to the survival of their groups. The effect of those struggles also troubled the act of writing itself making cooperation difficult on occasion, a mirror of the external social matrix.

    2008-01-01

    The minerals of chevkinite group were commonly considered to be anhydrous minerals. The infrared absorption spectrum of natural nonmetamict chevkinite-(Ce) from the aegirine-alkali granite, Mianning, Sichuan Province, China, exhibited two broad peaks in the 3600-2800 cm-1 region owing to the OH stretching. The corresponding H2O content required for the charge balance in formula was 1.27%. The O-H ··· O bond lengths maight cover from 0.2658 to 0.2794 nm by the correlated OH stretching energies. An electrostatic charge balance for chevkinite-(Ce) based on the assigned site-population from chemical data was calculated without the hydrogen contribution. The resulting empirical bond-valence sum on O6, O8, O2, O3, O5, and O4 ranged from 1.73 to 1.95 vu. The partial substitution of O by OH may occur in four atom sites: O6, O2, O4, and O5. The small differences in the bond-valence sums between the supposed donors and acceptors may mean a mixed donor/acceptor role of the involved oxygen atoms. The IR spectral features between 3394 and 3035 cm-1 consisted of various hydrous species at different structural sites and orientations. The OH groups in the chevkinite-(Ce) appeared to be involved in local charge imbalance in the structure and to be present when the mineral crystallized hydrothermally.

  17. Anomalous length dependence of conductance of aromatic nanoribbons with amine anchoring groups

    KAUST Repository

    Bilić, Ante

    2012-09-06

    Two sets of aromatic nanoribbons, based around a common hexagonal scaffolding, with single and dual terminal amine groups have been considered as potential molecular wires in a junction formed by gold leads. Charge transport through the two-terminal device has been modeled using density functional theory (with and without self-interaction correction) and the nonequilibrium Green\\'s function method. The effects of wire length, multiple terminal contacts, and pathways across the junction have been investigated. For nanoribbons with the oligopyrene motif and conventional single amine terminal groups, an increase in the wire length causes an exponential drop in the conductance. In contrast, for the nanoribbons with the oligoperylene motif and dual amine anchoring groups the predicted conductance rises with the wire length over the whole range of investigated lengths. Only when the effects of self-interaction correction are taken into account, the conductance of the oligoperylene ribbons exhibits saturation for longer members of the series. The oligoperylene nanoribbons, with dual amine groups at both terminals, show the potential to fully harness the highly conjugated system of π molecular orbitals across the junction. © 2012 American Physical Society.

    This research was sponsored by the Office of Buildings and Community Systems and conducted by the Pacific Northwest Laboratory as part of an ongoing effort to enhance the commercial use of federally developed technology. Federal dollars have supported research on the development of ground source heat pumps (GSHP) for several years. Though several companies currently sell GSHP's for residential use, their share of the total heating and air conditioning business remains less than one percent. Large manufacturing companies with national distribution have not yet added GSHP equipment to their product line. GSHP's use only about one half (Braud 1987) to one third (Bose 1987) of the energy needed to operate conventional furnaces and air conditioners. Consequently, a high level of market penetration by the GSHP offers direct benefits to both utility companies and individual users of the systems. Widespread use of these highly efficient systems will reduce both total energy consupmtion, and problems associated with high levels of energy use during peak periods. This will allow utility companies to delay capital expenditures for new facilities to meet the growing energy demand during peak periods. The cost effective use of electricity also reduces the likelihood of homeowners switching to a different fuel source for heating. 5 refs.

    Undergraduate medical students get fewer opportunities to clarify their doubts and to reinforce their understanding of concepts after lecture classes. There is no information available in the literature that addresses the question of usefulness of prior formulation of questions followed by small group discussion by undergraduate medical students as a revision exercise. The purpose of this work is to evaluate the effect of formulation of objective type short answer questions by undergraduate medical students followed by small group discussion on the answers of the questions prepared as a revision exercise on their understanding of the topic "amino acid metabolism" and the retention of the gain after 15 days. At the end of a regular teaching module on the topic of amino acid metabolism, undergraduate medical students were asked to prepare 16 objective type short answer questions on the various aspects of the topic as homework. Small group discussions involving 12-14 students in each group and lasting one hour were conducted on the questions and answers prepared by them in the presence of a faculty member. The effects on low, medium, and high achievers were evaluated with multiple choice questions by pre-test and post-tests before and after the group discussion. Formulation of questions was highly effective in improving understanding on the topic for all the students. The overall mean post-test scores after the formulation of questions (12.6) and after the small group discussion that followed (14.7) were significantly higher than the mean pre-test score (8.5). For high achievers, the gain from formulation of questions was higher than the gain from small group discussion. Small group discussion was highly effective for all students. The gain from small group discussion was higher among the low and medium achievers in comparison with the high achievers. The gain from the exercise was retained among the low, medium, and high achievers after 15 days. In conclusion

Im Projekt Globale Mediengenerationen (GMG wurden Medienerinnerungen aus der Kindheit im Kontext von Gruppendiskussionen am Beispiel dreier Generationen aus verschiedenen Ländern aller Kontinente untersucht. Dabei wurden medienbezogene Wissensbestände von drei Alterskohorten globaler Generationen analysiert. Der Artikel diskutiert methodologische Aspekte des Projekts und komplexe und selektive Prozesse des Erinnerns vergangener Ereignisse. Er untersucht Gemeinsamkeiten und Unterschiede des GMG-Ansatzes mit dem dokumentarischen Ansatz von Ralf Bohnsack, die beide in der Wissenssoziologie von Karl Mannheim verwurzelt sind. Darüber hinaus wird Medialität als basale methodologische Kategorie in Erwägung gezogen, nicht nur im Hinblick auf die Klärung begrifflicher Grundlagen, sondern auch als inhärente Dimension von Forschungsprozessen. Media events in general and the introduction and divulgence of new media technologies and formats in particular implicate various (new ways of “media entering life.” In the Global Media Generations (GMG research project, articulation of individuals’ memories of childhood experiences with the media was afforded by context of focus groups of three generations in different countries of six continents. In this project media related knowledge segments of different age cohorts have been analyzed and interpreted. The article deals with methodological questions of the project and complex processes of ‘remembering’ past events. It explores commonalities and differences of the GMG approach with Ralf Bohnsack’s documentary approach, both rooted in the sociology of knowledge of Karl Mannheim. Furthermore, mediality is taken into consideration as a basic methodological category, which means that it is perceived not only as subject matter to

The compounds exhibit similar conductance profiles, with a low conductance feature being more readily identified by STM-I(s) methods, and a higher feature by the STM-BJ method. The lower conductance feature was further characterised by analysis using an unsupervised, automated multi-parameter vector classification (MPVC) of the conductance traces. The combination of similarly structured HOMOs and non-resonant tunnelling mechanism accounts for the remarkably similar conductance values across the chemically distinct members of the family 2-5.

    Nunez Oviedo, Maria Cecilia

    The aim of this study was to describe co-construction processes in large group discussions. Co-construction, as used here, is a process by which the teacher and the students work together to construct and evaluate mental models of a target concept. Data were collected for an in-depth case study of a single teacher instructing middle school students with an innovative curriculum on human respiration. Data came from transcripts of video taped lessons, drawings, and pre- and post-test scores. Quantitative and qualitative analyses were conducted. In the quantitative analysis, differences in gains between one and two standard deviations in size were found between the pre- and post-test scores indicating that the students increased their understanding about human respiration. In the qualitative analysis, a generative exploratory method followed by a convergent coded method was conducted to examine teacher-student interaction patterns. The aim of this part was to determine how learning occurred by attempting to connect dialogue patterns with underlying cognitive processes. The main outcome of the study is a hypothesized model containing four layers of nested teaching strategies. Listed from large to small time scales these are: the Macro Cycle, the Co-construction Modes, the Micro Cycle, and the Teaching Tactics. The most intensive analysis focused on identifying and articulating the Co-construction Modes---Accretion Mode, Disconfirmation Mode, Modification Mode, Evolution Mode, and Competition Mode---and their relations to the other levels of the model. These modes can either describe the construction and evaluation of individual model elements or of entire models giving a total of ten modes. The frequency of these co-construction modes was then determined by coding, twenty-six hours of transcripts. The most frequent modes were the Accretion Mode and the Disconfirmation Mode. The teacher's and the students' contributions to the co-construction process were also examined

    Diabetes is a metabolic syndrome and the most common endocrine disorder in childhood and adolescence. Diabetes occurs at any age but the highest outbreak is during ten to 15 years of age and 75% of the cases are diagnosed at the age 18. This study aimed to investigate the effect of a group discussion on the quality of life (QOL) and glycosylated hemoglobin A (HbA1c) levels of adolescents with diabetes. This quasi-experimental study was performed on 56 adolescents with diabetes who were referred to Golabchi Diabetes Center in Kashan, Iran. After obtaining written informed consent from the patients, blood sample was drawn for measuring sugar and HbA1c levels. The participants completed the questionnaire regarding the QOL. Patients were randomly allocated to four groups. All the groups attended similar group discussion sessions, which were conducted according to the guidance of diabetic specialists. The groups' members followed the discussed instructions for four months. Then, another questionnaire was completed and blood sugar and HbA1c levels were measured again. The results were compared by paired-samples t-test and Wilcoxon signed-rank test. After the group discussion sessions, in 56% of the patients the HbA1c levels (8.45 ± 1.35 and 6.98 ± 0.89 before and after intervention, respectively) and QOL were improved significantly. The mean age of these patients was 14.75 ± 1.80 years and the mean of daily insulin injection was 35.70 ± 13.42 units. Sharing experiences trough group discussions and receiving instructive feedbacks can improve the QOL and metabolic status of adolescents with diabetes.

    Interpersonal and communication skills (IPCS) are essential for advanced practice nursing (APN) in our increasingly complex healthcare system. The Standardized Patient (SP) is a promising innovative pedagogy in medical and healthcare education; however, its effectiveness for teaching IPCS to graduate nursing students remains unclear. We examined the effectiveness of using SP with SP feedback and group discussion to teach IPCS in graduate nursing education. Randomized-controlled study. First-year APN students in Taiwan. Participants were randomly assigned to the experimental (SP assessments with SP feedback and group discussion) or control (SP assessments only) group. There were two outcome indicators: IPCS and student learning satisfaction (SLS). The IPCS were assessed before and after the study in interviews with the SPs. SLS was measured when the study ended. All participants expressed high SLS (94.44%) and showed significant (p ≤ 0.025) improvements on IPCS total scores, interviewing, and counseling. However, there were no significant differences between groups. Qualitative feedback from encounters with SPs is described. Using SPs to teach IPCS to APN students produced a high SLS. The students learned and significantly improved their IPCS by interviewing SPs, but future studies are needed to confirm the effectiveness of SP feedback and group discussions.

    Due, Karin

    2014-06-01

    This article describes a study which explored the social interaction and the reproduction and challenge of gendered discourses in small group discussions in physics. Data for the study consisted of video recordings of eight upper secondary school groups solving physics problems and 15 audiotaped individual interviews with participating students. The analysis was based on gender theory viewing gender both as a process and a discourse. Specifically discursive psychology analysis was used to examine how students position themselves and their peers within discourses of physics and gender. The results of the study reveal how images of physics and of "skilled physics student" were constructed in the context of the interviews. These discourses were reconstructed in the students' discussions and their social interactions within groups. Traditional gendered positions were reconstructed, for example with boys positioned as more competent in physics than girls. These positions were however also resisted and challenged.

    Initial efficacy of a magazine-based discussion group for improving physical activity (PA), self-worth, and eating behaviors in female college freshmen. Randomized control trial. A large university in southwestern United States. Thirty-seven female college freshmen were randomized to the intervention (n = 17) and control groups (n = 20) in September 2013. Participants completed an 8-week magazine-based discussion group program, Fit Minded College Edition, adapted from Fit Minded, a previously tested theory-based intervention. Education on PA, self-worth, and nutrition was provided using excerpts from women's health magazines. Participants also had access to a Web site with supplementary health and wellness material. The control group did not attend meetings or have access to the Web site but received the magazines. Interventions focusing on concepts of self-worth with less focus on weight and appearance may promote long term PA participation and healthy eating behaviors in college women. Self-reported PA, global self-worth, knowledge self-worth, self-efficacy, social support, eating behaviors (ie, fruit/veggie/junk food/sugar-sweetened beverage consumption), satisfaction, and Web site usage. Mean age of participants was 18.11 (SD = 0.32) years. Time × Intervention effects were observed for PA minutes per week (Partial η = 0.34), knowledge self-worth (Partial η = 0.02), and daily sugar-sweetened beverage consumption (Partial η = 0.17) (P < .05), with the intervention group reporting greater increases in PA and knowledge self-worth and greater decreases in sugar-sweetened beverage consumption. A magazine-based discussion group may provide a promising platform to improve health behaviors in female college freshmen.

    For the basic life support (BLS) renewal course, we have devised a new educational programme entitled a small-group-discussion (SGD) programme using personalised video-based debriefing. We compared the efficacy in BLS skill improvement of the SGD programme with the currently used practice-while-watching (PWW) programme, which uses a standardised education video. This was a prospective, cluster randomised study, conducted in a single centre, over 6 months from May 2009 to October 2009. Training was performed in two groups of participants, each group with a different renewal education programme. The efficacy of the programmes was compared using the modified Cardiff test and skill-reporting manikins. Results from 2169 participants were analysed: 1061 in the SGD programme group and 1108 in the PWW programme group. There were no differences between groups on the pretest, either in compression or non-compression skills. However, on the post-test, the SGD programme gave better results for both compression skills and non-compression skills. The new SGD renewal programme is more effective than the PWW programme for improving skills in BLS renewal training. Published by the BMJ Publishing Group Limited.

    In this study, we investigated the impact of scientific publications of the Italian SIMPAR (Study In Multidisciplinary PAin Research) group by using altmetrics, defined as nontraditional metrics constituting an alternative to more traditional citation-impact metrics, such as impact factor and H-index. By correlating traditional and alternative metrics, we attempted to verify whether publications by the SIMPAR group collectively had more impact than those performed by its individual members, either in solo publications or in publications coauthored by non-SIMPAR group investigators (which for the purpose of this study we will refer to as "individual publications"). For all the 12 members of the group analyzed (pain therapists, biologists, and pharmacologists), we created Open Researcher and Contributor ID and Impact Story accounts, and synchronized these data. Manually, we calculated the level metrics for each article by dividing the data obtained from the research community by those obtained from the public community. We analyzed 759 articles, 18 of which were published by the SIMPAR group. Altmetrics demonstrated that SIMPAR group publications were more likely to be saved (77.8% vs 45.9%), discussed (61.1% vs 1.1%, Paltmetrics in estimating the value of the research products of a group.

    A retrospective study of 112 cases of lupus erythematosus, 103 acute disseminated lupus erythematosus (ADLE) and 9 chronic discoid lupus (CDL), was conducted to determine the incidence of disorders of conduction (DC), and to study their prognosis and discuss their pathogenicity. The mean age of the group was 38 +/- 16 years, and the mean follow-up period after discovery of the DC was 53 months. Cardiac lesions were present in 49.5 p. cent of the 103 patients with ADLE : pericarditis in 27 p. cent, murmur from lupus endocarditis or cardiomyopathy in 23 p. cent, heart failure in 4.8 p. cent, and hypertension in 17 p. cent. Disorders of conduction were present in 18 (17.5 p. cent) of the 112 patients studied. These included 5 partial right bundle-branch blocks (no complete right bundle-branch block), 2 complete and 3 partial left bundle-branch blocks, 5 complete, 2 first degree, and 1 second degree atrioventricular blocks (AVB). The atrioventricular blocks were usually located in the truncal or fascicular regions, but in 2 cases they were nodal in origin. The 5 complete AVB were associated with ADLE in two cases and CDL in the three other cases. The AVB in the ADLE cases appeared 9 to 20 years after the onset of the lupus, these two patients developing pericardiomyocarditis unaccompanied by disorders of conduction. The three complete AVB occurring during CDL were detected 9 to 18 months after the diagnosis. A fatal outcome was noted in 13 (12.5 p. cent) of the ADLE patients and one of the 9 cases of CDL. Ten-year survival curves showed no difference in prognosis for the groups with or without disorders of conduction, but mortality increased in patients with DC after 10 years. As disorders of conduction were more frequently observed in patients with lupus than in a control population, they can be attributed to either a lupus myocarditis or prolonged administration of synthetic antimalarial agents. Disorders of conduction, and particularly complete AVB are, in fact

    Sexual minority (e.g. lesbian, gay, bisexual, questioning; LGBQ) and gender minority (e.g. transgender) youth experience myriad health risks. Gay-Straight Alliances (GSAs) are school-based settings where they may have opportunities to discuss substance use, mental health, and sexual health issues in ways that are safe and tailored to their experiences. Attention to these topics in GSAs could aid in developing programming for these settings. Among 295 youth from 33 Massachusetts high-school GSAs (69% LGBQ, 68% cisgender female, 68% White, Mage = 16.06), we examined how often youth discussed these topics within their GSA and identified factors associated with having more of these discussions. Youth and GSAs as a whole varied in their frequency of discussing these topics. Youth who accessed more information/resources in the GSA and did more advocacy more frequently engaged in discussions around substance use, mental health and sexual health. Youth who reported greater victimization more often discussed substance use and mental health, but not sexual health. Finally, GSAs whose members collectively reported greater victimization more frequently discussed these topics. These findings can assist the development of health programming to be delivered within GSAs. © The Author 2017. Published by Oxford University Press. All rights reserved.

    We establish a new group-contribution model based on the Nernst-Einstein equation in which the diffusion coefficient is derived from the modified double-lattice (MDL) model and the Debye-Huckel (DH) theory. The model includes the combinatorial energy contribution that is responsible for the revised Flory-Huggins entropy of mixing, the van der Waals energy contribution from dispersion, and the polar force and the specific energy contribution from hydrogen bonding. The Nernst-Einstein equation takes into account the mobility of the salt and the motion of the polymer host. To describe the segmental motion of the polymer chain, which is the well known conduction mechanism for solid polymer electrolyte (SPE) systems, the effective co-ordinated unit parameter is introduced. Our results show that good agreement is obtained upon comparison with experimental data of various PEO and salt systems in the interested ranges. (author)

    2016-04-01

    We examined the effect of group-IVA doping on the electronic structure and transmittance of ZnO using first-principle calculations. All these doped ZnO materials are found to perform n-type conductive behavior. Si-doped ZnO and Pb-doped ZnO are found to have larger optical band gap than those of Ge-doped ZnO and Sn-doped ZnO. The transmittance of Si-doped ZnO is found to be high in both UV and visible region. The enhancement of UV region transmittance can be attributed to the enhanced optical band gap, while the reduction of visible region transmittance is due to the intraband optical transition.

    Hydrosilylation reactions of 2.4.6.8-tetrahydro-2.4.6.8-tetramethylcyclotetrasiloxane with allyl butyrate catalyzed by Karstedt's, H2PtCl6 and Pt/C catalyst were studied and 2.4.6.8-tetra (propyl butyrate)-2.4.6.8-tetramethylcyclotetrasiloxane was obtained. The reaction order, activation energies and rate constants were determined. Ringopening polymerization of 2.4.6.8-tetra (propyl butyrate)-2.4.6.8-tetramethylcyclotetrasiloxane in the presence of CaF2, LiF, KF and anhydrous potassium hydroxide in 60-70 .deg. C temperature range was carried out and methylsiloxane oligomers with regular arrangement of propyl butyrate pendant groups were obtained. The synthesized products were studied by FTIR and NMR spectroscopy. The polysiloxanes were characterized by wide-angle X-ray, gel-permeation chromatography and DSC analyses. Via sol-gel processes of oligomers doped with lithium trifluoromethylsulfonate or lithium bis (trifluoromethylsulfonyl)imide, solid polymer electrolyte membranes were obtained. The dependences of ionic conductivity of obtained polyelectrolytes on temperature and salt concentration were investigated, and it was shown that electric conductivity of the polymer electrolyte membranes at room temperature changed in the range 3.5x10{sup -4} - 6.4xa0{sup -7} S/cm.

    In light of information uncovered about human radiation experiments conducted during the Cold War, an important charge for the Advisory Committee on Human Radiation Experiments was to assess the current state of protections for human research subjects. This assessment was designed to enhance the Committee's ability to make informed recommendations for the improvement of future policies and practices for the protection of research subjects. The Committee's examination of current protections revealed great improvement over those from the past, yet some problems remain. Although the data collected by the Committee highlight specific areas in need of attention, the Committee's work should be viewed in part as the beginning of a series of ongoing assessments of the adequacy and effectiveness of the protections afforded to human subjects.

  6. Selective traditions in group discussions: teachers' views about good science and the possible obstacles when encountering a new topic

    Science.gov (United States)

    Lundqvist, Eva; Sund, Per

    2016-11-01

    There is an ongoing discussion about what content that should be taught in science education and there are different views among teachers about what represent good science content. However, teachers are not isolated individuals making their own interpretations, but are part of institutionalised systems building on patterns in the selection of teaching goals and content. Earlier research shows that teachers teach in alignment with different selective traditions, which can be understood as well-developed teaching habits. Individual teachers seem to develop their personal habits on the basis of the contextual situations created by earlier generations of teachers. In order to find out which content teachers find representative for science education, we asked nine teachers to take part in group interviews to talk about what they value as "good" science content. The participants were grouped according to their selective traditions expressed in earlier studies. The method was used to dynamically explore, challenge and highlight teachers' views. The starting point for the group discussions is national tests in science. In Sweden, national tests in biology, physics and chemistry were introduced in secondary school science (year 9) in 2009. One overarching aim of these tests is to support the implementation of the science curricula and to include for example knowledge about socio-scientific issues (SSI). The content of the tests can consequently be seen as important for teachers to consider. The findings show that `resistance' to including SSI is not just an issue for individual teachers. As individuals teachers can create many kinds of obstacles, but still be interested in integrating SSI in their science teaching. However, in group discussions the teachers tend to collectively adopt the scientific rational discourse. This discourse is what joins them and creates their common identity as science teachers. In turn, they seek to free scientific knowledge from social knowledge

  7. Randomized controlled trial of group cognitive behavioral therapy compared to a discussion group for co-morbid anxiety and depression in older adults.

    Co-morbid anxiety and depression in older adults is associated with worse physical and mental health outcomes and poorer response to psychological and pharmacological treatments in older adults. However, there is a paucity of research focused on testing the efficacy of the co-morbid treatment of anxiety and depression in older adults using psychological interventions. Accordingly, the primary objective of the current study was to test the effects of a group cognitive behavior therapy (CBT) program in treating co-morbid anxiety and depression in a sample of older age adults. A total of 133 community-dwelling participants aged ⩾60 years (mean age = 67.35, s.d. = 5.44, male = 59) with both an anxiety disorder and unipolar mood disorder, as assessed on the Anxiety Disorder Interview Schedule (ADIS), were randomly allocated to an 11-week CBT group or discussion group. Participants with Mini-Mental State Examination scores group × time interaction effects emerged at post-treatment only for diagnostic severity of the primary disorder, mean severity of all anxiety disorders, mood disorders, and all disorders, and recovery rates on primary disorder. Group CBT produced faster and sustained improvements in anxiety and depression on diagnostic severity and recovery rates compared to an active control in older adults.

    Monitoring/supervision is an essential component for improving the quality of health services including rational use of medicines. A new bottom-up approach of monitoring/supervision consisting of self-assessment/ peer-group discussion was found to be effective in improving prescribing practices. The new strategy significantly improved the prescribing practices based on standard treatment guidelines. The government has implemented it as a Program in primary health care services of Nepal. This article aims to share the implementation status of the self-assessment/peer-group discussion Program for improving the prescribing practices of common health problems and availability of drugs in the district health system. Concurrent mixed research design was applied for data collection. The data were collected at different levels of health care system using in-depth interviews, participatory observations and documentary analysis. The Management Division, Department of Health Services implemented the Program in 2009-10 and the PHC Revitalization Division, DoHs is the implementation division since 2010-11. The Program comprised revision of participant's and trainer's manuals, training of trainers and prescribers, finalisation of health conditions and indicators, distribution of carbon copy prescription pads, and conduction of peer-group discussions.The Program was implemented in number of districts. The government made the policy decision to implement the Program for monitoring prescribing practices and the availability of free drugs in districts. However, it has covered only few districts and needs escalation to cover all 75 districts of the country.

    Full Text Available The authors focus their analysis in this article on online focus groups (FGs, in an attempt to describe how the setting shapes the conversational features of the discussion and influences data construction. Starting from a review of current dominant viewpoints, they compare face-to-face discussion groups with different formats of online FGs about AIDS, from a discourse analysis perspective. They conducted 2 face-to-face FGs, 2 chats, 2 forums, and 2 forums+plus+chat involving 64 participants aged 18 to 25 and living in Italy. Their findings seem not only to confirm the hypothesis of a general difference between a face-to-face discussion setting and an Internet-mediated one but also reveal differences among the forms of online FG, in terms of both the thematic articulation of discourse and the conversational and relational characteristics of group exchange, suggesting that exchanges on HIV/AIDS are characterized by the setting. This characterization seems to be important for situating the choice of tool, according to research objectives, and for better defining the technical aspects of the research project.

    This qualitative research study investigated intrapersonal, interpersonal, and environmental factors that shape young adolescent tobacco use behaviors in Uruguay. Focus groups were conducted in the summer of 2012 and fall of 2013 in four secondary schools in Montevideo, Uruguay, including two private schools and two public schools. A total of four focus groups were led in each school, composed of 4-6 students each, 16 focus groups in total. Data analysis utilized NVivo software and included deductive and inductive content analysis. Overwhelmingly, students reported that the onset of smoking occurred in the second year of secondary school. The primary intrapersonal factors that were found to be universal among respondents identified that smoking was a performance in groups, to garner attention from their peers. Students interviewed most often stated that the greatest interpersonal factors for smoking were to look older, as a rite of passage, and for group membership. Environmental factors cited most often indicate that they smoked during unsupervised time, either at night or around the short Uruguayan school day. Focus group interviews revealed that adolescents had easy access to cigarettes for purchase through small family owned grocery stores, even though laws exist preventing the sale of cigarettes to minors. Few differences were cited between strata related to cigarette use in adolescents. The differences that do exist are most apparent across gender, though there were a few observed differences when stratified by public and private school. Findings from this study indicate that key factors across ecological levels (intrapersonal, interpersonal, and environmental) should be taken into consideration when designing tobacco prevention programs for youth in Uruguay. A multiple-component approach which addresses risk factors at all of these levels, implemented in schools, may be particularly well-suited to this setting.

    Biosensor designs are emerging at a significant rate and play an increasingly important role in foodborne pathogen detection. Conducting polymers are excellent tools for the fabrication of biosensors and polypyrrole has been used in the detection of biomolecules due to its unique properties. The prime intention of this paper was to pioneer the design and fabrication of a single-strand (ss) DNA biosensor for the detection of the Bacillus cereus (B.cereus) group species. Growth of B. cereus, results in production of several highly active toxins. Therefore, consumption of food containing >106 bacteria/gm may results in emetic and diarrhoeal syndromes. The most common source of this bacterium is found in liquid food products, milk powder, mixed food products and is of particular concern in the baby formula industry. The electrochemical deposition technique, such as cyclic voltammetry, was used to develop and test a model DNA-based biosensor on a gold electrode electropolymerized with polypyrrole. The electrically conducting polymer, polypyrrole is used as a platform for immobilizing DNA (1μg) on the gold electrode surface, since it can be more easily deposited from neutral pH aqueous solutions of pyrrolemonomers. The average current peak during the electrodeposition event is 288μA. There is a clear change in the current after hybridization of the complementary oligonucleotide (6.35μA) and for the noncomplementary oligonucleotide (5.77μA). The drop in current after each event was clearly noticeable and it proved to be effective.

    Full Text Available Balaji Zacharia, Manu Paul, Mohammed Thanveeruddin Sherule Department of Orthopedics, Government Medical College, Kozhikode, Kerala, India Background: Total knee replacement (TKR results in an excellent outcome in terms of pain relief. The reporting of outcomes was traditionally focused on implant survivorship and objective outcomes such as range of motion, knee stability, and radiographic alignment. However, patients and doctors had differing perceptions of all domains of outcome, especially subjective quality of life domains such as emotions and social functioning. In this study, we tried to find out the expectations of Indian patients regarding TKR and assess the level of satisfaction among our patients from their view point using focus group discussion (FGD, and whether these expectations have an impact on outcomes and patient satisfaction. Materials and methods: This study was conducted in the Department of Orthopedics, Government Medical College, Kozhikode, Kerala, India, in November 2014. Patients between the ages 60 and 65 years who met inclusion criteria were selected. A total of 50 patients were selected for FGDs. Among them, 42 patients participated in FGD. The remaining eight did not appear for the discussion. A total of four FGD sessions were conducted. Results and discussion: It was found that there is a discrepancy between the satisfaction levels of patient and surgeon. There is a difference in satisfaction level achieved depending on socioeconomic, geographic, and cultural characteristics. Conclusion: Newer methods of TKR outcome assessment combining radiological outcome, surgeon-based assessment, and patient satisfaction based on their socioeconomic status and cultural characteristics should be developed for different populations.

    Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research.

    What do adolescent and young adult survivors of childhood cancer think about the risk of being infertile? The potential infertility, as well as the experience of having had cancer, affects well-being, intimate relationships and the desire to have children in the future. Many childhood cancer survivors want to have children and worry about possible infertility. For this qualitative study with a cross-sectional design, data were collected through 39 online focus group discussions during 2013. Cancer survivors previously treated for selected diagnoses were identified from The Swedish Childhood Cancer Register (16-24 years old at inclusion, ≥5 years after diagnosis) and approached regarding study participation. Online focus group discussions of mixed sex (n = 133) were performed on a chat platform in real time. Texts from the group discussions were analysed using qualitative content analysis. The analysis resulted in the main category Is it possible to have a baby? including five generic categories: Risk of infertility affects well-being, Dealing with possible infertility, Disclosure of possible infertility is a challenge, Issues related to heredity and Parenthood may be affected. The risk of infertility was described as having a negative impact on well-being and intimate relationships. Furthermore, the participants described hesitation about becoming a parent due to perceived or anticipated physical and psychological consequences of having had cancer. Given the sensitive topic of the study, the response rate (36%) is considered acceptable. The sample included participants who varied with regard to received fertility-related information, current fertility status and concerns related to the risk of being infertile. The results may be transferred to similar contexts with other groups of patients of childbearing age and a risk of impaired fertility due to disease. The findings imply that achieving parenthood, whether or not with biological children, is an area that

    Vitiligo is a chronic depigmenting skin disorder which affects around 0.5-1% of the world's population. The outcome measures used most commonly in trials to judge treatment success focus on repigmentation. Patient-reported outcome measures of treatment success are rarely used, although recommendations have been made for their inclusion in vitiligo trials. This study aimed to evaluate the face validity of a new patient-reported outcome measure of treatment response, for use in future trials and clinical practice. An online survey to gather initial views on what constitutes treatment success for people with vitiligo or their parents/carers, followed by online discussion groups with patients to reach consensus on what constitutes treatment success for individuals with vitiligo, and how this can be assessed in the context of trials. Participants were recruited from an existing database of vitiligo patients and through posts on the social network sites Facebook and Twitter. A total of 202 survey responses were received, of which 37 were excluded and 165 analysed. Three main themes emerged as important in assessing treatment response: a) the match between vitiligo and normal skin (how well it blends in); b) how noticeable the vitiligo is and c) a reduction in the size of the white patches. The majority of respondents said they would consider 80% or more repigmentation to be a worthwhile treatment response after 9 months of treatment. Three online discussion groups involving 12 participants led to consensus that treatment success is best measured by asking patients how noticeable their vitiligo is after treatment. This was judged to be best answered using a 5-point Likert scale, on which a score of 4 or 5 represents treatment success. This study represents the first step in developing a patient reported measure of treatment success in vitiligo trials. Further work is now needed to assess its construct validity and responsiveness to change.

    Full Text Available Daily life requires frequent estimations of the risk of falling and the ability to avoid a fall. The objective of this study was to explore older women's and men's understanding of fall risk and their experiences with safety precautions taken to prevent falls.A qualitative study with focus group discussions was conducted. Eighteen community-dwelling people [10 women and 8 men] with and without a history of falls were purposively recruited. Participants were divided into two groups, and each group met four times. A participatory and appreciative action and reflection approach was used to guide the discussions. All discussions were audio recorded and transcribed verbatim. Data were analysed by qualitative content analysis, and categories were determined inductively.Three categories describing the process of becoming aware of fall risks in everyday life were identified: 1] Facing various feelings, 2] Recognizing one's fall risk, and 3] Taking precautions. Each category comprised several subcategories. The comprehensive theme derived from the categories was "Safety precautions through fall risk awareness". Three strategies of ignoring [continuing a risky activity], gaining insight [realizing the danger in a certain situation], and anticipating [thinking ahead and acting in advance] were related to all choices of actions and could fluctuate in the same person in different contexts.The fall risk awareness process might be initiated for various reasons and can involve different feelings and precautions as well as different strategies. This finding highlights that there are many possible channels to reach older people with information about fall risk and fall prevention, including the media and their peers. The findings offer a deeper understanding of older peoples' conceptualizations about fall risk awareness and make an important contribution to the development and implementation of fall prevention programmes.

    Full Text Available Abstract Background Uneven distribution of the medical workforce is globally recognised, with widespread rural health workforce shortages. There has been substantial research on factors affecting recruitment and retention of rural doctors, but little has been done to establish the motives and conditions that encourage allied health professionals to practice rurally. This study aims to identify aspects of recruitment and retention of rural allied health professionals using qualitative methodology. Methods Six focus groups were conducted across rural NSW and analysed thematically using a grounded theory approach. The thirty allied health professionals participating in the focus groups were purposively sampled to represent a range of geographic locations, allied health professions, gender, age, and public or private work sectors. Results Five major themes emerged: personal factors; workload and type of work; continuing professional development (CPD; the impact of management; and career progression. ‘Pull factors’ favouring rural practice included: attraction to rural lifestyle; married or having family in the area; low cost of living; rural origin; personal engagement in the community; advanced work roles; a broad variety of challenging clinical work; and making a difference. ‘Push factors’ discouraging rural practice included: lack of employment opportunities for spouses; perceived inadequate quality of secondary schools; age related issues (retirement, desire for younger peer social interaction, and intention to travel; limited opportunity for career advancement; unmanageable workloads; and inadequate access to CPD. Having competent clinical managers mitigated the general frustration with health service management related to inappropriate service models and insufficient or inequitably distributed resources. Failure to fill vacant positions was of particular concern and frustration with the lack of CPD access was strongly represented by

    Directory of Open Access Journals (Sweden)

    Sarah V Kedenge

    Full Text Available BACKGROUND: There is considerable interest in the potential of private sector subsidies to increase availability and affordability of artemisinin-based combination therapies (ACTs for malaria treatment. A cluster randomized trial of such subsidies was conducted in 3 districts in Kenya, comprising provision of subsidized packs of paediatric ACT to retail outlets, training of retail staff, and community awareness activities. The results demonstrated a substantial increase in ACT availability and coverage, though patient counselling and adherence were suboptimal. We conducted a qualitative study in order to understand why these successes and limitations occurred. METHODOLOGY/PRINCIPAL FINDINGS: Eighteen focus group discussions were conducted, 9 with retailers and 9 with caregivers, to document experiences with the intervention. Respondents were positive about intervention components, praising the focused retailer training, affordable pricing, strong promotional activities, dispensing job aids, and consumer friendly packaging, which are likely to have contributed to the positive access and coverage outcomes observed. However, many retailers still did not stock ACT, due to insufficient supplies, lack of capital and staff turnover. Advice to caregivers was poor due to insufficient time, and poor recall of instructions. Adherence by caregivers to dosing guidelines was sub-optimal, because of a wish to save tablets for other episodes, doses being required at night, stopping treatment when the child felt better, and the number and bitter taste of the tablets. Caregivers used a number of strategies to obtain paediatric ACT for older age groups. CONCLUSIONS/SIGNIFICANCE: This study has highlighted that important components of a successful ACT subsidy intervention are regular retailer training, affordable pricing, a reliable supply chain and community mobilization emphasizing patient adherence and when to seek further care.

    Full Text Available Objective – This article discusses a series of actions taken by the Criss Library at the University of Nebraska at Omaha to implement organizational change, using the ClimateQUAL® survey and facilitated discussions with ThinkTank™ group decision software. The library had experienced significant changes over a five-year period, with a renovation of the facility and three reorganizations resulting in a 50% staff turnover. Recognizing the strain that years of construction and personnel changes had placed on the organization, there was a desire to uncover the mood of the employees and reveal the issues behind low morale, uneasiness, and fear.Methods – In November 2009, the library conducted a ClimateQUAL® survey to develop a baseline to assess the effectiveness of any changes. After the results were distributed to library faculty and staff, a series of two-hour facilitated discussions was held to gather opinions and ideas for solutions using thinkLets, a pattern language for reasoning toward a goal. The group support system ThinkTank™ software was loaded onto computers, and employees were able to add their ideas anonymously during the sessions. Finally, 12 employees (29% completed a four-question survey on their perceptions of the facilitated discussions.Results – The facilitated discussions returned 76 sub-themes in 12 categories: staffing and scheduling issues, staff unity/teamwork, communication, goodwill/morale, accountability, decision-making, policy issues, skills and training, leadership, ergonomics/physical work environment, respect, and bullying. An advisory team culled the 76 sub-themes into 40 improvement strategies. Five were implemented immediately, and the remaining 35 were scheduled to be presented to the faculty and staff via an online survey. Participants’ perceptions of the facilitated discussions were mixed. Eighty-three percent of respondents reported that they did not feel safe speaking out about issues, most

    Full Text Available BACKGROUND: A point-of-care test (POCT for sexually transmitted infections (STIs, which offers immediate diagnosis resulting in patients receiving diagnosis and treatment in a single visit, has the ability to address some of the STI control needs. However, needs assessment from STI experts and end users about currently available STI POCTs and their future new development has not been evaluated since World Health Organization Sexually Transmitted Diseases Diagnostics Initiative was formed over 15 years ago. Therefore, our objective was to explore the perceptions of the ideal types of STI POCT for use in health care settings. METHODOLOGY/PRINCIPAL FINDINGS: A qualitative study, encompassing eight focus groups, was conducted from March 2008 through April 2009. Participants included 6 STD clinic directors, 63 clinicians, and 7 public health/laboratory/epidemiology professionals in the STI field. Discussion topics included currently available POCT, perceived barriers to using POCT in clinics, priority STI for the development of new POCT, and characteristics of the ideal POCT. All discussions were recorded and transcribed verbatim. Themes raised as barriers for current POCT included complexity, long time frames of the so-called "rapid" test, multiple time-driven steps, requiring laboratory technician, difficulty in reading result, interruption of workflow, unreliability, and invasiveness. Chlamydia trachomatis was identified as the priority organism for development of a new STI POCT. Themes indicated for the ideal POCT included rapid turnaround (up to 20 minutes, ease of use, non-invasive, accurate (preferred sensitivity and specificity in the range of high 90s, Clinical Laboratory Improvement Amendments (CLIA-waived, user-friendly (for both patients and staff, compact, durable, and sturdy.

    In the nursing schools, the contrast between what is taught in the classrooms and what is practiced at the health care centers usually creates a great deal of confusion on the part of the students. The objective of this research is to ascertain the opinion of the students and of the professionals at the health care centers where they are doing their training with regard thereto in order to detect their problems and see what differences exist between primary and specialized care. This research was conducted throughout the first half of 2000 employing qualitative methodology, by means of four discussion groups comprised of students, former students, primary care training advisors and nursing professionals at the hospitals where the students of the school in question are doing their nursing training. The initial involvement employed was indirect. The comments of the nursing students and of their training advisors with regard to the practice nursing during the diploma studies reveal dissatisfaction on the part of both of these groups. In all of the groups point out anxiety as the leading factor involved in their teaching as well as learning activities and during professional training. The lack of identification as a group of professionals seems to be related to the lack of recognition on the part of the others, the demand for a degree being granted for their college studies and for the setting up of specialities would contribute to their social recognition and, as a result thereof, to their identification as a professional group. Until a solution is provided to the anxiety which the nursing professionals feel with regard to their professional practice, which they pass on to their students during nursing training, it will not be possible to achieve a higher degree of satisfaction with nursing training experiences either on the part of the training advisors or on the part of the students.

    The hyperbranched polymers (HBP-SA-Acs) with both a sulfonic acid group as a functional group and an acryloyl group as a cross-linker at terminals in different ratios of sulfonic acid group/acryloyl group (SO{sub 3}H/Ac) were successfully synthesized as a new thermally stable proton-conducting electrolyte. The cross-linked hyperbranched polymer electrolyte membranes (CL-HBP-SAs) were prepared by thermal polymerizations of the HBP-SA-Acs using benzoyl peroxide, and their ionic conductivities under dry condition and thermal properties were investigated. The ionic conductivities of the CL-HBP-SAs were found to be in the range of 2.2 x 10{sup -4} to 3.3 x 10{sup -6} S/cm, depending upon the SO{sub 3}H unit contents, at 150 deg. C under dry condition, and showed the Vogel-Tamman-Fulcher (VTF) type temperature dependence, indicating that proton transfer is cooperated by local polymer chain motion. All CL-HBP-SAs were thermally stable up to 260 deg. C, and they had suitable thermal stability as electrolyte membranes for the high-temperature fuel cells under dry condition. Fuel cell measurement using a single membrane electrode assembly cell with a cross-linked electrolyte membrane was successfully performed under non-humidified condition. It was demonstrated that applying the concept of dry polymer system to proton conduction is one possible approach toward high-temperature fuel cells.

    Anemia is a major contributor to morbidity and mortality among women of reproductive age. Progress toward reducing the burden of anemia has been little despite efforts through decades. We conducted this study to unearth the microlevel determinants of anemia among women of reproductive age. This qualitative study was conducted in Urban Health Centre (UHC), Chetla. A focus group discussion was held among all the eight health staffs, who were involved in reproductive and child health-related service delivery under UHC, Chetla. A thematic analysis of the transcript was performed. We found that socioeconomic factors like poverty and social neglect, diet and nutrition related factors, lack of personal hygiene, and worm infestation contributed to the burden of anemia, and this was reinforced by factors related to service delivery, such as lack of supply of drugs and supplements, and inadequate training of health workers as well as poor media accountability. Because of easy reversibility and implementation, health service delivery-related issues should be addressed closely through monitoring and evaluation and appropriate and timely action should be taken to improve the effectiveness of the services.

    Teaching methods that provide an opportunity for individual engagement and focussed feedback are required to create an active learning environment for case-based teaching in large groups. A prospective observational controlled study was conducted to evaluate whether the use of an audience response system (ARS) would promote an active learning environment during case-based discussions in large groups, have an impact on student motivation and improve long-term retention. Group A (N = 83) participated in large group case discussions where student participation was voluntary, while for group B (N = 86) an ARS was used. Data collection methods included student and teacher surveys, student focus group interviews, independent observations and 1-year post-course testing. Results indicated that the use of an ARS provided an active learning environment during case-based discussions in large groups by favouring engagement, observation and critical reflection and by increasing student and teacher motivation. Although final exam results were significantly improved in group B, long-term retention was not significantly different between groups. It was concluded that ARS use significantly improved the learning experience associated with case-based discussions in a large group of undergraduate students.

    Full Text Available Different tools and techniques of participatory approaches are the basic way of conducting qualitative research especially in the field of applied social science. Focus Group Discussion (FGD is one of the main Participatory Rural Appraisal (PRA technique often used in combination with others to achieve desired goals. Considering this concept, this paper attempts to review the PRA approach and then application of FGD, in combination with matrix scoring and ranking to identify problems and causes of climate change along with possible mitigation and adaptation strategies. A group of 20 students at post graduate level under the faculty of Agriculture and Horticulture at Humboldt University of Berlin, Germany those from different corner of the world was considered as target people of the study. The results concluded that “unpredictable weather events” was ranked as the present outstanding visible climate change problem caused by “human activities”. However, it was noted that if alternative renewable energy sources are exploited, this could contribute to solving the present climate change problem. This finding might have the good reference for the policy makers in the same line not only for developing countries but also for developed countries.

    Computer-assisted data collection offers advantages over traditional paper and pencil measures; however, little guidance is available regarding the logistics of conducting computer-assisted data collection with adolescents in group settings. To address this gap, we draw on our experiences conducting a multi-site longitudinal study of adolescent development. Structured questionnaires programmed on laptop computers using Audio Computer Assisted Self-Interviewing (ACASI) were administered to groups of adolescents in community-based and afterschool programs. Although implementing ACASI required additional work before entering the field, we benefited from reduced data processing time, high data quality, and high levels of youth motivation. Preliminary findings from an ethnically diverse sample of 265 youth indicate favorable perceptions of using ACASI. Using our experiences as a case study, we provide recommendations on selecting an appropriate data collection device (including hardware and software), preparing and testing the ACASI, conducting data collection in the field, and managing data.

    Socio-scientific issues in class have been proposed in an effort to democratise science in society. A micro-ethnographic approach has been used to explore how students elaborate arguments on a socio-scientific controversy in the context of small group discussions. Several processes of group argumentation have been identified. Students’ arguments were elaborated from scientific data, common ideas and epistemological and strategic considerations. Students’ social interactions influenced the patterns of argumentation elaborated within the group discussions. Implications of this study for the teaching of socio-scientific issues in class are discussed.

    Poly(4-[[(4-methylphenyl)methylene]amino]phenol) (P(4-MMAP)), which is a Schiff base polymer, was synthesized by an oxidative polycondensation reaction of 4-[[(4-methylphenyl)methylene]amino]phenol (4-MMAP) with the oxidants NaOCl, H2O2 and O2 in an aqueous alkaline medium. The polymerizations were carried out at various temperatures and times, and the highest polymer yield could be obtained when using 37% with NaOCl oxidant. The structures of the monomer and polymer were characterized by UV-Vis, FTIR 1H NMR and X-ray diffraction techniques. The thermal behaviors of the monomer and polymer were identified by the TG and DTG techniques. The thermal degradation of the polymer which was observed thermally stable up to 1000 °C, was also supported by the Thermo-IR spectra recorded in the temperature range of 25-800 °C. The number average molecular weight (Mn), weight average molecular weight (Mw) and polydispersity index (PDI) of the polymer were found to be 16682, 57796 g/mol and 3.4, respectively. The highest electrical conductivity value of P(4-MMAP) doped with iodine vapor at different temperatures and times was measured to be 7.8 × 10-5 Scm-1 after doping for 48 h at 60 °C. The antibacterial and antifungal activities of 4-MMAP and P(4-MMAP) were also assayed against the bacteria Sarcina lutea, Enterobacter aerogenes, Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Bacillus subtilis and the fungi Candida albicans, Saccharomyces cerevisiae, respectively.

    Full Text Available Each company is surrounded by the micro- and macro-environment affecting also its economic performance. These factors are not only individual accounting entries, but also analytical inputs as the internal company processes, management of costs or short-term financial decisions and specifically in the case of agriculture within the EU also the public subsidy schemes implemented through the EU Common Agricultural Policy. Groups of agricultural producers are created as a response to current market dynamics and the opportunity for each agricultural enterprise regardless the size. In this paper, the basis for agricultural cooperation is provided, traditional economic performance measures are presented and their applicability on the sample of agricultural producers’ groups and wholesale entities is empirically verified. Wholesale entities are analysed by its business activity and performance features to consider whether they are suitable peer group for comparing economic performance of examined agricultural producers’ group. Since the economic performance of agricultural producers’ groups directly affects the economic performance of all participating entities, and vice versa, their economic performance measurement may involve specific constraints. According to the structure and characteristics of agricultural producers’ groups may be inferred that whilst the common performance measurement techniques are applicable on the majority of companies, agricultural producers’ groups represent specific entities and therefore need adjusted performance measurement approach.

    Fast Track is a multisite, multicomponent preventive intervention for young children at high risk for long-term antisocial behavior. Based on a comprehensive developmental model, intervention included a universal-level classroom program plus social skills training, academic tutoring, parent training, and home visiting to improve competencies and reduce problems in a high-risk group of children selected in kindergarten. At the end of Grade 1, there were moderate positive effects on children's social, emotional, and academic skills; peer interactions and social status; and conduct problems and special-education use. Parents reported less physical discipline and greater parenting satisfaction/ease of parenting and engaged in more appropriate/consistent discipline, warmth/positive involvement, and involvement with the school. Evidence of differential intervention effects across child gender, race, site, and cohort was minimal.

    A novel mixed zirconium phosphate/phosphonate based on glyphosine, of formula Zr2(PO4)H5(L)2·H2O [L = (O3PCH2)2NCH2COO], was synthesized in mild conditions. The compound has a layered structure that was solved ab initio from laboratory PXRD data. It crystallizes in the monoclinic C2/c space group with the following cell parameters: a = 29.925(3), b = 8.4225(5), c = 9.0985(4) Å, and β = 98.474(6)°. Phosphate groups are placed inside the sheets and connect the zirconium atoms in a tetradentate fashion, while uncoordinated carboxylate and P-OH phosphonate groups are exposed on the layer surface. Due to the presence of these acidic groups, the compound showed remarkable proton conductivity properties, which were studied in a wide range of temperature and relative humidity (RH). The conductivity is strongly dependent on RH and reaches 1 × 10(-3) S cm(-1) at 140 °C and 95% RH. At this RH, the activation energy of conduction is 0.15 eV in the temperature range 80-140 °C. The similarities of this structure with related structures already reported in the literature were also discussed.

    In cat peroneus tertius muscles, static gamma axons were prepared in groups of three to four according to the conduction velocity of their axons (fast, intermediate, or slow). Effects of stimulating these groups (at 20, 30, and 50 Hz) on spindle ensemble discharges during sinusoidal stretch (peak-to-peak amplitude, 0.5 mm; frequency linearly increasing from 0.5 to 8 Hz in 10 s) were compared. Ensemble discharges were obtained by digital treatment of the discharges in afferent fibers from all the spindles in peroneus tertius as recorded from the muscle nerve. Stimulation of each group prevented ensemble discharges from falling to very low levels during shortening phases. However, this effect was clearly larger when the group of fast-conducting axons was stimulated. In view of the known effects of the activation of bag(2) and chain fibers (either separately or together) on single primary ending discharges during comparable sinusoidal stretches, this stronger effect supports the view that static gamma axons with faster conduction velocities are more likely to supply more bag(2) fibers than slower ones. Possibly the proportions of bag(2) and chain fibers activated during motor activity are determined by a recruitment of static gamma motoneurons related to their size.

    Primary health care (PHC) outreach teams are part of a policy of PHC re-engineering in South Africa. It attempts to move the deployment of community health workers (CHWs) from vertical programmes into an integrated generalised team-based approach to care for defined populations in municipal wards. There has little evaluation of PHC outreach teams. Managers' insights are anecdotal. This is descriptive qualitative study with focus group discussions with health district managers of Johannesburg, the largest city in South Africa. This was conducted in a sequence of three meetings with questions around implementation, human resources, and integrated PHC teamwork. There was a thematic content analysis of validated transcripts using the framework method. There were two major themes: leadership-management challenges and human resource challenges. Whilst there was some positive sentiment, leadership-management challenges loomed large: poor leadership and planning with an under-resourced centralised approach, poor communications both within the service and with community, concerns with its impact on current services and resistance to change, and poor integration, both with other streams of PHC re-engineering and current district programmes. Discussion by managers on human resources was mostly on the plight of CHWs and calls for formalisation of CHWs functioning and training and nurse challenges with inappropriate planning and deployment of the team structure, with brief mention of the extended team. Whilst there is positive sentiment towards intent of the PHC outreach team, programme managers in Johannesburg were critical of management of the programme in their health district. Whilst the objective of PHC reform is people-centred health care, its implementation struggles with a centralising tendency amongst managers in the health service in South Africa. Managers in Johannesburg advocated for decentralisation. The implementation of PHC outreach teams is also limited by

    The two different molecular weight hyperbranched polymers (HBP(L)-PA-Ac and HBP(H)-PA-Ac) with both phosphonic acid group as a functional group and acryloyl group as a cross-linker at the chain ends were successfully synthesized as a new thermally stable proton-conducting electrolyte. The cross-linked electrolyte membranes (CL-HBP-PA) were prepared by their thermal polymerizations using benzoyl peroxide and their ionic conductivities under dry condition and thermal properties were investigated. The ionic conductivities of the low molecular weight CL-HBP(L)-PA membrane and the high molecular weight CL-HBP(H)-PA membrane were found to be 1.2 x 10{sup -5} and 2.6 x 10{sup -6} S cm{sup -1}, respectively, at 150 C under dry condition, and showed the Vogel-Tamman-Fulcher (VTF) type temperature dependence. Both membranes were thermally stable up to 300 C, and they had suitable thermal stability as electrolyte membranes for the high-temperature fuel cells under dry condition. Fuel cell measurements using a single membrane electrode assembly cell with both cross-linked membranes were successfully performed. (author)

    It has been well-established that discussion groups enhance student learning in large lecture courses. The goal of this study was to determine the impact of a discussion group program on the development of conceptual reasoning skills of students enrolled in a large lecture-format introductory biology course. In the discussion group, students worked on problems based on topics discussed in lecture. The program was evaluated using three assessment tools. First, student responses to pre- and posttests were analyzed. The test question asked the students to demonstrate the relationships between 10 different but related terms. Use of a concept map to link the terms indicated an advanced level of conceptual reasoning skills. There was a 13.8% increase in the use of concept maps from pre- to posttest. Second, the students took a Likert-type survey to determine the perceived impact of the program on their conceptual reasoning skills. Many of the students felt that the program helped them understand and use the main course concepts to logically solve problems. Finally, average exam grades increased as the semester progressed. The average final grade in the course was 75%. Students enrolled in the course the previous year (where the lecture component of the course did not assess or reflect student learning in the discussion group) had an average final grade of 69%. The results of this study demonstrate that the discussion group program improves the conceptual reasoning skills of students enrolled in a large lecture-format introductory biology course.

  17. Online Focus Group Discussion is a Valid and Feasible Mode When Investigating Sensitive Topics Among Young Persons With a Cancer Experience.

    Clinical research often lacks participants of young age. Adding to the small amount of scientific studies that focus on the population entering adulthood, there are also difficulties to recruit them. To overcome this, there is a need to develop and scientifically evaluate modes for data collection that are suitable for adolescents and young adults. With this in mind we performed 39 online focus group discussions among young survivors of childhood cancer to explore thoughts and experiences around dating, being intimate with someone, and having children. The aim of the study was to evaluate online focus group discussions as a mode for data collection on sensitive issues among young persons with a cancer experience. One hundred thirty-three young persons (16-25 years) previously diagnosed with cancer, participated in 39 synchronous online focus group discussions (response rate 134/369, 36%). The mode of administration was evaluated by analyzing participant characteristics and interactions during discussions, as well as group members' evaluations of the discussions. Persons diagnosed with central nervous tumors (n=30, 27%) participated to a lower extent than those with other cancer types (n=103, 39%; χ 2= 4.89, P=.03). The participants described various health impairments that correspond to what would be expected among cancer survivors including neuropsychiatric conditions and writing disabilities. Even though participants were interested in others' experiences, sexual issues needed more probing by the moderators than did fertility-related issues. Group evaluations revealed that participants appreciated communicating on the suggested topics and thought that it was easier to discuss sex when it was possible to be anonymous toward other group members. Online focus group discussions, with anonymous participation, are suggested to be a feasible and valid mode for collecting sensitive data among young persons with a cancer experience.

    Full Text Available This edited volume comprises a range of studies that have employed a group discussion technique in combination with a specific strategy for reconstructive social research—the so-called documentary method. The latter is an empirical research strategy based on the meta-theoretical premises of the praxeological sociology of knowledge, as developed by Ralf BOHNSACK. It seeks to access practice in a more appropriate manner, namely by differentiating between various dimensions of knowledge and sociality. It holds that habitual collective orientations, in particular, are best accessed through group discussions. Thus this book does not address the group discussion technique in general, as might be expected from the title. Instead, it presents various contributions from researchers interpreting transcripts of group discussions according to the documentary method. The chapters are grouped into three main sections, representing different frameworks of practice and habitual orientation: childhood, adolescence, and organizational or societal context. A fourth section includes chapters on further, potentially useful ways of employing this particular technique and approach, as well as a chapter on teaching it in a meaningful way. Each chapter is structured in the same way: introduction to the research field and focus; methodological discussion; exemplary interpretation of group discussions; and concluding remarks. Whilst the transcripts referred to by the authors are very helpfully presented in the chapters, there is a lack of methodological reflection on the group discussion technique itself, which, as mentioned above, is only evaluated in regard to the documentary method.

    Full Text Available Lie detection procedures typically aim at determining the guilt or innocence of a single suspect. The Concealed Information Test (CIT, for example, has been shown to be highly successful in detecting the presence or absence of crime-related information in a suspect’s memory. Many of today’s security threats, however, do not come from individuals, but from organized groups such as criminal organizations or terrorist networks. In this study, we tested whether a plan of an upcoming mock terrorist attack could be extracted from a group of suspects using a dynamic questioning approach. One-hundred participants were tested in 20 groups of 5. Each group was asked to plan a mock terrorist attack based on a list of potential countries, cities and streets. Next, three questions referring to the country, city, and street were presented, each with 5 options. Skin conductance in all 5 members of the group was measured simultaneously during this presentation. The dynamic questioning approach entailed direct analysis of the data, and if the average skin conductance of the group to a certain option exceeded a threshold, this option was followed up. E.g., if the reaction to the option ‘Italy’ exceeded the threshold, this was followed up by presenting 5 cities in Italy. Results showed that in 19 of the 20 groups the country was correctly detected using this procedure. In 13 of these remaining 19 groups the city was correctly detected. In 7 of these 13, the street was also correctly detected. The question about the country resulted in no false positives (out of 20, the question about the city resulted in 2 false positives (out of 19, while the question about the streets resulted in 2 false positives (out of 13. Furthermore, the 2 false positives at the city level also yielded a false positive at the street level. Taken together these results indicate our dynamic questioning approach can help to unveil plans about a mock terrorist attack.

    A novel series of aromatic block copolymers composed of fluorinated phenylene and biphenylene groups and diphenyl ether (QPE-bl-5) or diphenyl sulfide (QPE-bl-6) groups as a scaffold for quaternized ammonium groups is reported. The block copolymers were synthesized via aromatic nucleophilic substitution polycondensation, chloromethylation, quaternization, and ion exchange reactions. The block copolymers were soluble in organic solvents and provided thin and bendable membranes by solution casting. The membranes exhibited well-developed phase-separated morphology based on the hydrophilic/hydrophobic block copolymer structure. The membranes exhibited mechanical stability as confirmed by DMA (dynamic mechanical analyses) and low gas and hydrazine permeability. The QPE-bl-5 membrane with the highest ion exchange capacity (IEC = 2.1 mequiv g(-1)) exhibited high hydroxide ion conductivity (62 mS cm(-1)) in water at 80 °C. A noble metal-free fuel cell was fabricated with the QPE-bl-5 as the membrane and electrode binder. The fuel cell operated with hydrazine as a fuel exhibited a maximum power density of 176 mW cm(-2) at a current density of 451 mA cm(-2).

    2012-04-01

    The advent of eLearning has seen online discussion forums widely used in both undergraduate and postgraduate nursing education. This paper reports an Australian university experience of design, delivery and redevelopment of a distance education module developed for Vietnamese nurse academics. The teaching experience of Vietnamese nurse academics is mixed and frequently limited. It was decided that the distance module should attempt to utilise the experience of senior Vietnamese nurse academics - asynchronous online discussion groups were used to facilitate this. Online discussion occurred in both Vietnamese and English and was moderated by an Australian academic working alongside a Vietnamese translator. This paper will discuss the design of an online learning environment for foreign correspondents, the resources and translation required to maximise the success of asynchronous online discussion groups, as well as the rationale of delivering complex content in a foreign language. While specifically addressing the first iteration of the first distance module designed, this paper will also address subsequent changes made for the second iteration of the module and comment on their success. While a translator is clearly a key component of success, the elements of simplicity and clarity combined with supportive online moderation must not be overlooked.

    This paper presents preliminary outcomes associated with an experimental, longitudinal study of a Multiple Family Group (MFG) service delivery approach set within thirteen urban outpatient clinics serving children and their families living in inner-city, primarily African American and Latino communities. Specifically, this paper focuses on parent reports of child oppositional behavior and parenting stress over time. MFG is a flexible, protocol-driven approach designed to address the most common reason for referral to outpatient child mental health clinics, childhood behavioral difficulties. The MFG also aims to enhance family-level engagement and retention in ongoing care. Further, the service delivery model was collaboratively developed with intensive input from parents rearing children with conduct difficulties, parent advocates, community-based child mental health providers and services research staff in order to ultimately expand the number of effective service models that can be situated within "real world," urban child mental health settings.

    2016-05-01

    Background Burnout is common in internal medicine (IM) trainees and is associated with depression and suboptimal patient care. Facilitated group discussion reduces burnout among practicing clinicians. Objective We hypothesized that this type of intervention would reduce incident burnout among first-year IM residents. Methods Between June 2013 and May 2014, participants from a convenience sample of 51 incoming IM residents were randomly assigned (in groups of 3) to the intervention or a control. Twice-monthly theme-based discussion sessions (18 total) led by expert facilitators were held for intervention groups. Surveys were administered at study onset and completion. Demographic and personal characteristics were collected. Burnout and burnout domains were the primary outcomes. Following convention, we defined burnout as a high emotional exhaustion or depersonalization score on the Maslach Burnout Inventory. Results All 51 eligible residents participated; 39 (76%) completed both surveys. Initial burnout prevalence (10 of 21 [48%] versus 7 of 17 [41%], P = .69), incidence of burnout at year end (9 of 11 [82%] versus 5 of 10 [50%], P = .18), and secondary outcomes were similar in intervention and control arms. More residents in the intervention group had high year-end depersonalization scores (18 of 21 [86%] versus 9 of 17 [53%], P = .04). Many intervention residents revealed that sessions did not truly free them from clinical or educational responsibilities. Conclusions A facilitated group discussion intervention did not decrease burnout in resident physicians. Future discussion-based interventions for reducing resident burnout should be voluntary and effectively free participants from clinical duties.

  11. Stomatal and mesophyll conductances to CO₂ in different plant groups: underrated factors for predicting leaf photosynthesis responses to climate change?

    The climate change conditions predicted for the end of the current century are expected to have an impact on the performance of plants under natural conditions. The variables which are foreseen to have a larger effect are increased CO2 concentration and temperature. Although it is generally considered CO2 assimilation rate could be increased by the increasing levels of CO2, it has been reported in previous studies that acclimation to high CO2 results in reductions of physiological parameters involved in photosynthesis, like the maximum carboxylation rate (Vc,max), stomatal conductance (gs) and mesophyll conductance to CO2 (gm). On the one hand, most of the previous modeling efforts have neglected the potential role played by the acclimation of gm to high CO2 and temperature. On the other hand, the effect of climate change on plant clades other than angiosperms, like ferns, has received little attention, and there are no studies evaluating the potential impact of increasing CO2 and temperature on these species. In this study we predicted responses of several representative species among angiosperms, gymnosperms and ferns to increasing CO2 and temperature. Our results show that species with lower photosynthetic capacity - such as some ferns and gymnosperms - would be proportionally more favored under these foreseen environmental conditions. The main reason for this difference is the lower diffusion limitation imposed by gs and gm in plants having high capacity for photosynthesis among the angiosperms, which reduces the positive effect of increasing CO2. However, this apparent advantage of low-diffusion species would be canceled if the two conductances - gs and gm - acclimate and are down regulated to high CO2, which is basically unknown, especially for gymnosperms and ferns. Hence, for a better understanding of different plant responses to future climate, studies are urged in which the actual photosynthetic response/acclimation to increased CO2 and temperature of

    Group III nitrides (AlN, GaN, and InN) consist of the semiconductors which appear recently as a basic materials for optoelectronic devices active in the visible/ultraviolet spectrum as well as high-temperature and high-power microelectronic devices. However, understanding of the basic physical properties leading to application is still not satisfactory. One of the reasons consists in unsufficient knowledge of the band structure of the considered semiconductors. Several theoretical studies of III-nitrides band structure have been published but relatively few experimental studies have been carried out, particularly with respect to their conduction band structure. This motivated the authors to examine the conduction band structure projected onto p-states of the nitrogen atoms for AlN, GaN and InN. An additional advantage of their studies is the availability of the studied nitrides in two structures, hexagonal (wurtzite) and cubic (zincblende). This offers an opportunity to gain information about the role of the anisotropy of electronic band states in determining various physical properties.

      Giving children and young people information about genetic conditions and associated risk has been shown to be important to their identity, coping and decision making. Parents, however, find talking to their children difficult, and support from health professionals is often not available to them.   To explore the role of support groups in family coping, and in assisting parents' communication about risk with children in families affected by an inherited genetic condition.   Semi-structured interviews analysed using grounded theory and informed by models focusing on aspects of family communication.   Affected and unaffected children and their parents, from families affected by one of six genetic conditions, that represent different patterns of inheritance, and variations in age of onset, life expectancy and impact on families.   Parents often sought support they did not receive elsewhere from support groups. They identified benefits, but also potential disadvantages to this involvement. These related to the specific condition and also whether groups were run solely by parents or had professional input. Support groups rarely helped directly with family communication, but attendance often stimulated family discussion, and they provided information that improved parents' confidence in discussing the condition.   Support groups should be seen only as additional to the support offered by health and social care professionals. An increased understanding of the role of support groups in assisting families with genetic conditions has been highlighted, but further work is needed to explore more fully how this may be made more sustainable and far-reaching. © 2011 Blackwell Publishing Ltd.

    The Zuni Pueblo is home to an economically disadvantaged population, which faces a public health challenge from the interrelated epidemics of obesity, diabetes and kidney disease. Efforts to decrease the impact of these epidemics have been complicated by historical, economic and cultural barriers, which may limit healthcare utilization. The NIH supported Zuni Health Initiative (ZHI) conducted a study to identify barriers to healthcare in the Zuni Pueblo. Community health representatives (CHRs) led 14 one-hour focus group sessions at which a total of 112 people participated posed unique questions that took into account the Zuni culture to elicit information on perceived barriers to healthcare. Audiotapes were translated and transcribed by bilingual ZHI staff. We reduced the text to thematic categories, constructed a coding dictionary and inserted the text into NVivo 9 program. We identified nine themes emerged regarding the barriers experienced in receiving healthcare and adhering to medical advice. These included distance; transportation; embarrassment; relating to healthcare professionals; navigating the medical system; awareness of available resources; waiting times; adhering to medication; and incentives in health promotion. In conclusion the implementation of culturally appropriate community-based health promotion programs and preventive screening techniques will improve access to healthcare and diminish health disparities. © 2013 Wiley Periodicals, Inc.

    This commentary summarizes a small-group discussion that recently occurred at the American Society for Microbiology annual general meeting, ASM Microbe, in Boston, Massachusetts, on 16-20 June 2016, on the topic 'why are so few women choosing to become academics?' Specifically, the discussion focused on asking what the actual and perceived barriers to academic STEM careers women face, and possible solutions to address them which would make women more likely to seek out academic careers. The conclusions reached suggest that, despite improvement in recent years, women and minorities still face complex barriers to STEM academic careers, and further research is needed to determine the best solutions to this problem. © FEMS 2017.

    The project was a result of the authority's continued work on the 1998 regulations on protection of human health and the environment in final disposal of spent nuclear fuel and nuclear waste. The idea behind the project, to involve persons from the municipalities participating in SKB's site selection investigation in focus group discussions, was that the questions and points of views that emerged in the discussions could serve as a basis for the authority's work of producing general guidelines associated with the regulations. The finished report would then be handed over to an expert group at the authority which answered or commented on the issues raised, and made a report on this to the participating municipalities Oskarshamn and Oesthammar. The result of discussions in two focus groups in Oskarshamn municipality and two in Oesthammar municipality in October 2002 is presented here, together with a presentation of the project's purpose and organisation. The results are presented in three main sections. The first concentrates on radiation and radioactivity since the task in the discussion groups was to attempt to clarify the issues and problems observed in this area in order to contribute to the authority's work of developing the general guidelines. The second section, on understanding of concepts, measurement, risk and safety, illustrates that the frequently asked and 'simple' knowledge related questions are only the tip of the iceberg where many of the participants have also thought about the more complex contexts and the fundamental problems in the risk and safety analysis, its validity and use. The third section of the report focuses primarily on content and information aspects. It provides a number of ideas about how information on current problems and important issues can be improved, how knowledge can be deepened in the site selection municipalities and how working methods in the process can be developed.

    Full Text Available Non-exclusive breast feeding in the early years of life is one of the most important factors in growth and development of infants. Therefore, exclusive breast feeding is recommended during the first six months of life. For determining the effective factors of non-exclusive breast feeding during the first six months of life, we used focus group discussion by participation of 60 mothers who had an infant under 6 months age and enjoyed non-exclusive breast feeding. Mothers divided into eight groups considering their occupation and number of child. All groups reported scanty of mother’s milk, mother’s occupation, mother’s illness, mother’s comfort, wrong beliefs, infant’s illness, doctors and health care providers recommendations, infant’s dependency to feeding bottle and pacifiers as the most frequent factors in using nonexclusive breast feeding. All mothers believed that health care centers, relatives and older members of family, books and pamphlets, mass media, physicians were their effective sources of awareness and promotion of exclusive breast feeding. Considering the presented ideas in all groups, it is realized that mothers during their pregnancy have sparse information about exclusive breast feeding and because of lack of enough essential training, some socio – cultural beliefs affects non-exclusive breast feeding. Mass media and especial training programs should be implemented to promote exclusive breast feeding in Bushehr Port.

  5. An exploration of computer-simulated evolution and small group discussion on pre-service science teachers' perceptions of evolutionary concepts

    MacDonald, Ronald Douglas

    The primary goal of this study was to explore how the use of a computer simulation of basic evolutionary processes, in combination with small-group discussions, affected Intermediate/Senior pre-service science teachers' perspectives of basic evolutionary concepts. Qualitative and quantitative methods were used in a case study approach with 19 pre-service Intermediate/Senior science teachers at an Ontario university. Several sub-goals were explored. The first sub-goal was to assess Intermediate/Senior pre-service science teachers' current conceptions of evolution. The results indicated that approximately two-thirds of the participants had a poor understanding of basic evolutionary concepts, with only 2 of the 19 participants demonstrating a strong comprehension. These results were found to be very similar to comparable samples of subjects from other research. The second sub-goal was to explore the relationships among Intermediate/Senior pre-service science teachers' understanding of contemporary evolutionary concepts, their perspectives of the nature of science, and their intentions to teach evolutionary concepts in the classroom. Participants' knowledge of evolutionary concepts was found to be associated strongly with their intentions to teach evolution by natural selection (r = .42). However, knowledge of evolutionary concepts was not found to be associated with any particular science epistemology perspective. The third sub-goal was to analyze and to interpret the small-group discussions as members interacted with the simulation. The simulation was found to be highly engaging and a very effective method of encouraging participants to speculate, question, discuss and learn about important evolutionary concepts. Analyses of the discussions revealed that the simulation evoked a wide array of correct conceptions as well as misconceptions. The fourth sub-goal was to assess the extent to which creating a lesson plan on the topic of natural selection could affect

    The delivery of safe and effective radical cure for Plasmodium vivax is one of the greatest challenges for achieving malaria elimination from the Asia-Pacific by 2030. During the annual meeting of the Asia Pacific Malaria Elimination Network Vivax Working Group in October 2016, a round table discussion was held to discuss the programmatic issues hindering the widespread use of primaquine (PQ) radical cure. Participants included 73 representatives from 16 partner countries and 33 institutional partners and other research institutes. In this meeting report, the key discussion points are presented and grouped into five themes: (i) current barriers for glucose-6-phosphate deficiency (G6PD) testing prior to PQ radical cure, (ii) necessary properties of G6PD tests for wide scale deployment, (iii) the promotion of G6PD testing, (iv) improving adherence to PQ regimens and (v) the challenges for future tafenoquine (TQ) roll out. Robust point of care (PoC) G6PD tests are needed, which are suitable and cost-effective for clinical settings with limited infrastructure. An affordable and competitive test price is needed, accompanied by sustainable funding for the product with appropriate training of healthcare staff, and robust quality control and assurance processes. In the absence of quantitative PoC G6PD tests, G6PD status can be gauged with qualitative diagnostics, however none of the available tests is currently sensitive enough to guide TQ treatment. TQ introduction will require overcoming additional challenges including the management of severely and intermediately G6PD deficient individuals. Robust strategies are needed to ensure that effective treatment practices can be deployed widely, and these should ensure that the caveats are outweighed by  the benefits of radical cure for both the patients and the community. Widespread access to quality controlled G6PD testing will be critical.

    Full Text Available Based predominantly on Pierre Bourdieu’s social and cultural reproduction theory, particularly his notions of cultural capital and symbolic violence, this paper explores how first year post graduate Diploma in Higher Education (PGDHE university students from diverse socio-linguistic backgrounds differ in the levels at which they understand and express themselves in classroom activities. The paper’s thesis is that the diverse nature of South African classrooms presents a number of challenges not only for students but also for educators in terms of the use of English as a medium of instruction or the language for learning and teaching (LOLT. Owing to the fact that the South African Language in Education Policy (LiEP of 1997 empowers both learners and educators in schools to use any of the eleven South African official languages as a LOLT wherever that is reasonably possible, students whose English backgrounds were deficient in enculturating them in the use of English as a learning tool often encounter challenges in expressing their ideas in the classroom, whether in writing or in oral presentations. The discussion is anchored in the data elicited through two data collection methods, lesson observations in a Diploma in Higher Education, Research class composed of students from diverse racial and ethnic backgrounds and through focus group discussion sessions with 40 multi-ethnic Diploma in Higher Education students from the same classroom. The data management and analysis for this study was done thematically, with views emerging from the observations and focus group discussions being clustered into superordinate themes for convenience of the discussion of the findings. The findings of this study were that students from affluent socio-economic backgrounds who enter university with a rich and relevant English linguistic capital, values and attitudes enjoy an enormous advantage compared to their counterparts whose social class and linguistic

    For the past 3 yr, faculty at the University of New Mexico, Department of Biochemistry and Molecular Biology have been using interactive online Problem-Based Learning (PBL) case discussions in our large-enrollment classes. We have developed an illustrative tracking method to monitor student use of problem-solving strategies to provide targeted help to groups and to individual students. This method of assessing performance has a high interrater reliability, and senior students, with training, can serve as reliable graders. We have been able to measure improvements in many students' problem-solving strategies, but, not unexpectedly, there is a population of students who consistently apply the same failing strategy when there is no faculty intervention. This new methodology provides an effective tool to direct faculty to constructively intercede in this area of student development.

    Preterm infants are usually breastfed less than full-term infants, and successful breastfeeding requires a supportive environment and special efforts from their mothers. A breastfeeding peer-support group, utilising social media, was developed for these mothers in order to support them in this challenge. Mothers were able to discuss breastfeeding and share experiences. The purpose of this study was to describe the perceptions of breastfeeding mothers of preterm infants based on the postings in peer-support group discussions in social media. The actively participating mothers (n = 22) had given birth <35 gestational weeks. They were recruited from one university hospital in Finland. The social media postings (n = 305) were analysed using thematic analysis. A description of the process of breastfeeding a preterm infant from the point of view of a mother was created. The process consisted of three main themes: the breastfeeding paradox in hospital, the 'reality check' of breastfeeding at home and the breastfeeding experience as part of being a mother. The mothers encountered paradoxical elements in the support received in hospital; discharge was promoted at the expense of breastfeeding and pumping breast milk was emphasised over breastfeeding. After the infant's discharge, the over-optimistic expectations of mothers often met with reality - mothers did not have the knowledge or skills to manage breastfeeding at home. Successful breastfeeding was an empowering experience for the mothers, whereas unsuccessful breastfeeding induced feelings of disappointment. Therefore, the mothers of preterm infants need evidence-based breastfeeding counselling and systematic support in a neonatal intensive care unit (NICU) and at home. © 2014 John Wiley & Sons Ltd.

    Introduction This study seeks to explore whether the documented decline in medical student empathy can be prevented or slowed using simulated patient-role activities and small-group discussions about the patient experience of living with a chronic illness. Methods First-year students (M1, n = 118) at the University of Central Florida College of Medicine (UCFCOM) participated in a simulated patient-role activity resembling the experience of a patient with Type 2 diabetes mellitus. The activity included taking daily "medication," participating in moderate exercise, and maintaining a low carbohydrate diet. At the end of the simulated patient-role activity, students took part in a small-group discussion about their experiences. Students completed the Jefferson Scale of Physician Empathy: Student Version (JSPE:S) before and after the activity. Additionally, fourth-year students (M4) at UCFCOM completed the JSPE:S to serve as the control, as this class completed the curriculum without any simulated patient-role activities. Results A total of 86 responses out of 118 possible M1 participants (73% response rate) were received. Of these, 62 surveys were completed and were therefore used for statistical analysis. A dependent sample t-test revealed no statistically significant increase on pre-activity (M = 111.15, SD = 8.56) and post-activity (M = 111.38, SD = 9.12) empathy scores (p = .78). A positive correlation was revealed to exist between pre- and post-activity empathy scores (r = 0.72, p students, our findings suggest that on a short-term scale, empathy levels were not affected by the activity.

    Vulnerability is a broad concept widely addressed in recent scholarly literature. Lesbian, gay, bisexual, and transgender (LGBT) people are among the vulnerable populations with significant disadvantages related to health and the social determinants of health. Medical ethics discourse tackles vulnerability from philosophical and political perspectives. LGBT people experience several disadvantages from both perspectives. This article aims to justify the right to health for LGBT people and their particular claims regarding healthcare because they belong to a vulnerable group. Rawls' theory of justice and Norman Daniels' normal functioning approach will be discussed in this context. Despite the fact that the right to health can be justified by Daniels' normal functioning approach, there is still a theoretical gap in justifying the right to health for particular vulnerable populations such as LGBT peopleand discussing society's duty to compensate for these disadvantages. In search of solid theoretical grounds for the justification of the right to health for LGBT people, the present author takes the opportunity to utilize Daniels' flexible definition of normal functioning to show that normal functioning not only varies by age but also by different states of human existence, including sexual orientation and gender identity, and to propose replacing the life span approach with normal states of human existence.

    Full Text Available Introduction: Vestibular evoked myogenic potential (VEMP has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients.   Materials and Methods: We performed a cross sectional analysis on 20 healthy volunteers with normal pure-tone audiometry as a control group; and on a group of patients consisted of 20 participants with conductive hearing loss, five with bilateral sensorineural hearing loss and four with vestibular schawannoma. AC and BC-VEMP were performed in all participants.   Results: In control group the VEMP responses to both kinds of stimuli had an acceptable morphology and consisted of p13 and n23 waves. Latency value of these main components in each type of stimulus was not significantly different (P>0.05. However, the mean amplitude was larger in BC modality than AC stimulation (P=0.025. In the group with conductive hearing loss, the VEMP response was absent in fifteen (46.87% of the 32 ears using the AC method, whereas all (100% displayed positive elicitability of VEMP by BC method. Normal VEMP responses in both stimuli were evoked in all patients with sensorineural hearing loss. In patients with unilateral vestibular schwannomas (VS, 2 (50.00% had neither AC-VEMP nor BC-VEMP. Conclusion:  Auditory stimuli delivered by bone conduction can evoke VEMP response. These responses are of vestibular origin and can be used in vestibular evaluation of patients with conductive hearing loss.

    Full Text Available Students who are entitled to get into a university in our country usually live with their families. However, when a student gets into a university which is far away or when it is difficult to go and return, one of the problems which their family has to solve is housing. Housing place alternatives might be government owned hostel, private hostel or houses for rent. The young student who has lived with their family until that age may find themselves in a different environment. This life might make the young people gain socialization, sense of responsibility and sharing, being able to manage their lives in the community - and it might also make them gain qualifications like being able to make discrimination between good and bad. The basic objective of this research is to identify the effects of housing place on individual and social development. The research has been applied to the students of Kocaeli University, Karamürsel Vocational High School . For the research, five focus group discussions have been carried out, each of which is formed of 8 participants and one assistant. In the study which was carried out based on question and answer, 3 general to special questions were directed . Group members have been formed of students who stay in house and hostel also students who stay with their own family. Maximum diversity sampling has been executed. According to the results, it appears that most essential contributions of staying in a hostel are mainly information sharing, growing mature, learning about recognizing human beings, being able to make discrimination between good and bad, learning about trusting, learning about making more moderate spending, and being able to make decisions freely. Besides, participants stated that any type of environment was available for studying both in governmental hostel and in housing environment, and studying in groups increases their successes.

Com o objetivo de discutir temas de Saúde Mental relevantes para o trabalho cotidiano desses profissionais, criou-se um espaço de aprendizagem e construção de sentido para esses agentes. Em grupos de encontro quinzenais com uma psiquiatra e cerca de 20 agentes, discutiam-se casos clínicos e situações de vida e trabalho a partir dos quais era possível aprender conceitos básicos de Saúde Mental e pensar o papel e a identidade desses profissionais na comunidade. Ao final de um ano de experiência, avaliou-se que tal atividade é fundamental como apoio para o desenvolvimento do trabalho desses profissionais, e para o aprendizado de como lidar com aspectos subjetivos próprios e dos usuários, especialmente na periferia de grandes centros urbanos.This article describes a teaching experience with health community agents in a Family Health Program unit. In order to discuss important everyday mental health themes, a space for these agents was created, intended for learning and building up senses. Groups of 20 agents and a psychiatrist met every two weeks, to discuss clinical cases, and life and work situations which helped apprehend basic Mental Health concepts and to reflect on the role and identity of these professionals in the community. After one year, this activity was considered fundamental to support the work developed by the agents and to help them learn how to deal with their and the users' subjective aspects, especially in the periphery of large urban centers.

    An investigation is made of the magnetic Rayleigh problem where a semi-infinite plate is given an impulsive motion and thereafter moves with constant velocity in a nonNewtonian power law fluid of infinite extent. The solution of this highly non-linear problem is obtained by means of the transformation group theoretic approach. The one-parameter group transformation reduces the number of independent variables by one and the governing partial differential equation with the boundary conditions reduce to an ordinary differential equation with the appropriate boundary conditions. Effect of the some parameters on the velocity u ( y, t) has been studied and the results are plotted.

    Objectives Several ABILHAND Rasch-built manual ability scales were previously developed for chronic stroke (CS), cerebral palsy (CP), rheumatoid arthritis (RA), systemic sclerosis (SSc) and neuromuscular disorders (NMD). The present study aimed to explore the applicability of a generic manual ability scale unbiased by diagnosis and to study the nature of manual ability across diagnoses. Design Cross-sectional study. Setting Outpatient clinic homes (CS, CP, RA), specialised centres (CP), reference centres (CP, NMD) and university hospitals (SSc). Participants 762 patients from six diagnostic groups: 103 CS adults, 113 CP children, 112 RA adults, 156 SSc adults, 124 NMD children and 124 NMD adults. Primary and secondary outcome measures Manual ability as measured by the ABILHAND disease-specific questionnaires, diagnosis and nature (ie, uni-manual or bi-manual involvement and proximal or distal joints involvement) of the ABILHAND manual activities. Results The difficulties of most manual activities were diagnosis dependent. A principal component analysis highlighted that 57% of the variance in the item difficulty between diagnoses was explained by the symmetric or asymmetric nature of the disorders. A generic scale was constructed, from a metric point of view, with 11 items sharing a common difficulty among diagnoses and 41 items displaying a category-specific location (asymmetric: CS, CP; and symmetric: RA, SSc, NMD). This generic scale showed that CP and NMD children had significantly less manual ability than RA patients, who had significantly less manual ability than CS, SSc and NMD adults. However, the generic scale was less discriminative and responsive to small deficits than disease-specific instruments. Conclusions Our finding that most of the manual item difficulties were disease-dependent emphasises the danger of using generic scales without prior investigation of item invariance across diagnostic groups. Nevertheless, a generic manual ability scale could be

    Ringlike polar monomer maleic anhydride (MAn) was copolymerized with oligo (oxyethylene)methacrylate (MEOn), and its effect on ion conduction property of the corresponding polymer-salt complexes was studied. As a consequence the introduction of MAn onto polymer chain retards crystallization of the ether pendants considerably, and improves the ion conductivity to a larger degree compared with other polar groups once investigated (σmax,25 ℃ = 8.5 × 10-5 S/cm). The structure-ion conduction relation in the polymer- salt matrix is also analyzed macroscopically through the correspondence between composition-dependences of polymerization conversion and isothermal ion conductivity, and microscopically through the measurements of cross polarized light and electron transmission.

    Full Text Available [english] Aims: Interactive, student-centered teaching methods have replaced traditional teacher-centered didactic formats in many modern medical curricula in the past few years. However, in the natural sciences such as biochemistry, interactive teaching methods are not well proven. The present study was conducted to compare the effect of the teaching format on the performance of undergraduate students in biochemistry and their evaluation of the respective format. Methods: A total of 421 second-year students were randomized into two groups: The control group was taught in a traditional lecture-like format, whereas the study group dealt with the same topic in an interactive group discussion. At the end of each lesson, students performed a multiple-choice test and completed a questionnaire. The same MCQ test was repeated 4–6 weeks after the last lesson. Results: Students who were taught in a lecture-like format performed significantly better in the first MCQ test immediately after the lesson than students taught in the interactive format. However, in the second MCQ test, there was no difference between the two groups. In the questionnaire, students rated the lecture-based course significantly better than the interactive group discussion. Conclusion: One reason why students prefer a didactic lecture to an interactive group discussion might be due to the subject biochemistry, which is strongly knowledge-based. Students perceived that the transfer of knowledge by a professional lecturer was more effective than the knowledge obtained in a student-centered discussion group. Other reasons might be the method of assessment and the overall design of the curriculum.

    The electrical properties of single-molecule junctions, consisting of an organic molecule coupled to metal electrodes, are sensitive to the detailed atomic structure of the molecule-metal contact. This, in turn, is determined by the anchoring group linking the molecule to the metal. With the aim...... of identifying and comparing the intrinsic properties of two commonly used anchoring groups, namely thiol and amine groups, we have calculated the atomic structure and conductance traces of different Au-S-Au and Au-NH2-Au nanojunctions using density functional theory (DFT). Whereas NH2 shows a strong structural...... selectivity towards atop-gold configurations, S shows large variability in its bonding geometries. As a result, the conductance of the Au-NH2-Au junction is less sensitive to the structure of the gold contacts than the Au-S-Au junction. These findings support recent experiments which show that amine...

    For studies using respondent driven sampling (RDS), the current practice of collecting a sample twice as large as that used in simple random sampling (SRS) (i.e. design effect of 2.00) may not be sufficient. This paper provides empirical evidence of sample-to-sample variability in design effects using data from nine studies in six countries among injecting drug users, female sex workers, men who have sex with men and male-to-female transgender (MTF) persons. We computed the design effect as the variance under RDS divided by the variance under SRS for a broad range of demographic and behavioral variables in each study. We also estimated several measures for each variable in each study that we hypothesized might be related to design effect: the number of waves needed for equilibrium, homophily, and mean network size. Design effects for all studies ranged from 1.20 to 5.90. Mean design effects among all studies ranged from 1.50 to 3.70. A particularly high design effect was found for employment status (design effect of 5.90) of MTF in Peru. This may be explained by a "bottleneck"--defined as the occurrence of a relatively small number of recruitment ties between two groups in the population. A design effect of two for RDS studies may not be sufficient. Since the mean design effect across all studies was 2.33, an effect slightly above 2.00 may be adequate; however, an effect closer to 3.00 or 4.00 might be more appropriate.

    Efficient thermoelectric (TE) energy conversion requires materials with low thermal conductivity and good electronic properties. Si-Ge alloys, and their nanostructures such as thin films and nanowires, have been extensively studied for TE applications; other group-IV alloys, including those containing Sn, have not been given as much attention as TEs, despite their increasing applications in other areas including optoelectronics. We study the lattice thermal conductivity of binary (Si-Sn and Ge-Sn) and ternary (Si-Ge-Sn) alloys and their thin films in the Boltzmann transport formalisms, including a full phonon dispersion and momentum-dependent boundary-roughness scattering. We show that Si-Sn alloys have the lowest conductivity (3 W /mK ) of all the bulk alloys, more than 2 times lower than Si-Ge, attributed to the larger difference in mass between the two constituents. In addition, we demonstrate that thin films offer an additional reduction in thermal conductivity, reaching around 1 W /mK in 20-nm-thick Si-Sn, Ge-Sn, and ternary Si-Ge-Sn films, which is near the conductivity of amorphous SiO2 . We conclude that group-IV alloys containing Sn have the potential for high-efficiency TE energy conversion.

    The diagnosis conduct disorder (CD) is characterized by aggressive (e.g., physical aggression) as well as nonaggressive symptoms (e.g., violation of rules, truancy). Conclusions regarding the course and prognosis, or recommendations for effective interventions, seem not to be equally valid for the whole patient group. DSM-IV-TR included subtyping age-of-onset as a prognostic criterion, even though the evidence base for subtyping from age of onset was rather sparse. The relevant literature on CD has grown substantially since the publication of DSM-IV-TR in 1994. For the new DSM-5 edition, some important issues were discussed, for example, consideration of personality traits, female-specific or dimensional criteria, and adding a childhood-limited subtype (Moffitt et al., 2008). Nevertheless, the diagnostic protocol for CD was not changed in the most parts in the new edition of the DSM-5; the addition of a CD specifier with limited emotions is the most relevant change. On the basis of the existing evidence base, this review discusses whether the modifications in DSM-5 are helpful for fulfilling the requirements of a reliable and valid psychiatric classification.

  18. What is CCZN-armalcolite? A crystal-chemical discussion and an ad-hoc incursion in the crichtonite-minerals group

    Directory of Open Access Journals (Sweden)

    Gavril Sabau

    2007-10-01

    Full Text Available The status of CCZN-armalcolite, commonly still believed to be a variety of armalcolite s.s., is questionable in view of partial evidence suggesting that it would represent a distinct phase, as initially claimed by its discoverers. Because of the rarity of the mineral, combined with its habitual small grain-size, no successful structural investigation could be undertaken so far. Therefore we attempted a chemical overview of existing and original data pertaining to CCZN-armalcolite. With the view of systematizing structure-composition relationships, we analyzed the topology of large cations – bearing close-packed oxides, while extending the nomenclature in use in order to accommodate further topologies. By using relevant chemical plots, a fair compositional match between CCZN-armalcolite and the crichtonite group minerals was demonstrated, as well as a chemical incompatibility with armalcolite. Stoichiometric crichtonite compositions and matching optical properties allowed identification of at least part of “CCZN-armalcolites” with the mineral loveringite of the crichtonite group. A detailed inspection of structure-composition relationships in crichtonites allowed an insight in their trends and range of chemical variation, as well as a comparison between them and a group of “CCZN-armalcolites” slightly differing from known crichtonites. These “CCZN-armalcolites” departing from normal chemical trends in crichtonites either represent an ordered variety of non-stoichiometric crichtonite or a new group of close-packed oxides. Their composition clustering around formula AM16O30 is temptingly consistent with an hypothetical structure intermediate between magnetoplumbites and crichtonites, based on close-packed stacking of layers made up by triangular clusters of octahedra, stuffed with large cations. A model of such a structure, not encountered so far in minerals, is outlined, displaying a hexagonal symmetry P , with a ≈ 7.45Å and c

  1. The influence on response of axial rotation of a six-group local-conductance probe in horizontal oil-water two-phase flow

    Science.gov (United States)

    Weihang, Kong; Lingfu, Kong; Lei, Li; Xingbin, Liu; Tao, Cui

    2017-06-01

    Water volume fraction is an important parameter of two-phase flow measurement, and it is an urgent task for accurate measurement in horizontal oil field development and optimization of oil production. The previous ring-shaped conductance water-cut meter cannot obtain the response values corresponding to the oil field water conductivity for oil-water two-phase flow in horizontal oil-producing wells characterized by low yield liquid, low velocity and high water cut. Hence, an inserted axisymmetric array structure sensor, i.e. a six-group local-conductance probe (SGLCP), is proposed in this paper. Firstly, the electric field distributions generated by the exciting electrodes of SGLCP are investigated by the finite element method (FEM), and the spatial sensitivity distributions of SGLCP are analyzed from the aspect of different separations between two electrodes and different axial rotation angles respectively. Secondly, the numerical simulation responses of SGLCP in horizontal segregated flow are calculated from the aspect of different water cut and heights of the water layer, respectively. Lastly, an SGLCP-based well logging instrument was developed, and experiments were carried out in a horizontal pipe with an inner diameter of 125 mm on the industrial-scale experimental multiphase flow setup in the Daqing Oilfield, China. In the experiments, the different oil-water two-phase flow, mineralization degree, temperature and pressure were tested. The results obtained from the simulation experiments and simulation well experiments demonstrate that the designed and developed SGLCP-based instrument still has a good response characteristic for measuring water conductivity under the different conditions mentioned above. The validity and reliability of obtaining the response values corresponding to the water conductivity through the designed and developed SGLCP-based instrument are verified by the experimental results. The significance of this work can provide an effective

  9. Stable two-channel Kondo fixed point of an SU(3) quantum defect in a metal: renormalization-group analysis and conductance spikes.

    Science.gov (United States)

    Arnold, Michael; Langenbruch, Tobias; Kroha, Johann

    2007-11-02

    We propose a physical realization of the two-channel Kondo (2CK) effect, where a dynamical defect in a metal has a unique ground state and twofold degenerate excited states. In a wide range of parameters the interactions with the electrons renormalize the excited doublet downward below the bare defect ground state, thus stabilizing the 2CK fixed point. In addition to the Kondo temperature T(K) the three-state defect exhibits another low-energy scale, associated with ground-to-excited-state transitions, which can be exponentially smaller than T(K). Using the perturbative nonequilibrium renormalization group we demonstrate that this can provide the long-sought explanation of the sharp conductance spikes observed by Ralph and Buhrman in ultrasmall metallic point contacts.

    A novel Schiff base polymer containing phenol group, Poly(3-[[4-(dimethylamino)benzylidene]amino]phenol) P(3-DBAP), was prepared by oxidative polycondensation reaction of 3-[[4-(dimethylamino)benzylidene]amino]phenol (3-DBAP) using NaOCl, H2O2, O2 oxidants in aqueous alkaline medium. Yield and molecular weight distribution of P(3-DBAP) were monitored depending on oxidant types and concentration, monomer concentration and as well as polymerization temperature and time. UV-Vis, FTIR and 1HNMR techniques were used to identify the structures of Schiff base monomer and polymer. Thermal behavior of P(3-DBAP), which was determined to be thermally stable up to 1200 °C via TG-DTG techniques, was illuminated by Thermo-IR spectra recorded in the temperature range of 25-800 °C. It was determined that the electrical conductivity value of the P(3-DBAP) increased 108 fold after doped with iodine for 24 h at 60 °C according to undoped form and it was measured 4.6 × 10-4 S/cm. Also, antibacterial and antifungal activities of the monomer and polymer were assayed against Sarcina lutea, Enterobacter aerogenes, Escherichia coli, Enterococcus Feacalis, Klebsiella pneumoniae, Bacillus subtilis bacteria, and Candida albicans, Saccharomyces cerevisiae fungi.

Healthcare staff and managers (n=13) from the two settings. Two workshops were performed, one at each setting. Workshops were initiated by a short introduction to simulation modelling. Results from the respective simulation model were then presented and discussed in the following focus group discussion. Categories from the content analysis are presented according to the following research questions: how and when simulation modelling can assist healthcare improvement? Regarding how, the participants mentioned that simulation modelling could act as a tool for support and a way to visualise problems, potential solutions and their effects. Regarding when, simulation modelling could be used both locally and by management, as well as a pedagogical tool to develop and test innovative ideas and to involve everyone in the improvement work. Its potential as an information and communication tool and as an instrument for pedagogic work within healthcare improvement render a broader application and value of simulation modelling than previously reported. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    We compare two settings for administering time trade-off (TTO) tasks in computer-assisted interviews (one-to-one, interviewer-led versus group, self-complete) by examining the quality of the data generated in pilot studies undertaken in England and the Netherlands. The two studies used near-identical methods, except that in England, data were collected in one-to-one interviews with substantial amounts of interviewer assistance, whereas in the Netherlands, the computer aid was used as a self-completion tool in group interviews with lesser amounts of interviewer assistance. In total, 801 members of the general public (403 in England; 398 in the Netherlands) each completed five TTO valuations of EQ-5D-5L health states. Respondents in the Netherlands study showed a greater tendency to give 'round number' values such as 0 and 1 and to complete tasks using a minimal number of iterative steps. They also showed a greater tendency to skip the animated instructions that preceded the first task and to take into account assumptions that they were specifically asked not to take into account. When faced with a pair of health states in which one state dominated the other, respondents in the Netherlands study were more likely than those in the England study to give a higher value to the dominant health state. On the basis of these comparisons, we conclude that the one-to-one, interviewer-led setting is superior to the group, self-complete setting in terms of the quality of data generated and that the former is more suitable than the latter for TTO studies being used to value EQ-5D-5L.

    1989-01-01

    An experimental Round Robin on the measurement of the opening load in fatigue crack growth tests was conducted on Crack Closure Measurement and Analysis. The Round Robin evaluated the current level of consistency of opening load measurements among laboratories and to identify causes for observed inconsistency. Eleven laboratories participated in the testing of compact and middle-crack specimens. Opening-load measurements were made for crack growth at two stress-intensity factor levels, three crack lengths, and following an overload. All opening-load measurements were based on the analysis of specimen compliance data. When all of the results reported (from all participants, all measurement methods, and all data analysis methods) for a given test condition were pooled, the range of opening loads was very large--typically spanning the lower half of the fatigue loading cycle. Part of the large scatter in the reported opening-load results was ascribed to consistent differences in results produced by the various methods used to measure specimen compliance and to evaluate the opening load from the compliance data. Another significant portion of the scatter was ascribed to lab-to-lab differences in producing the compliance data when using nominally the same method of measurement.

    A second experimental Round Robin on the measurement of the crack opening load in fatigue crack growth tests has been completed by the ASTM Task Group E24.04.04 on Crack Closure Measurement and Analysis. Fourteen laboratories participated in the testing of aluminum alloy compact tension specimens. Opening-load measurements were made at three crack lengths during constant Delta K, constant stress ratio tests by most of the participants. Four participants made opening-load measurements during threshold tests. All opening-load measurements were based on the analysis of specimens compliance behavior, where the displacement/strain was measured either at the crack mouth or the mid-height back face location. The Round Robin data were analyzed for opening load using two non-subjective analysis methods: the compliance offset and the correlation coefficient methods. The scatter in the opening load results was significantly reduced when some of the results were excluded from the analysis population based on an accept/reject criterion for raw data quality. The compliance offset and correlation coefficient opening load analysis methods produced similar results for data populations that had been screened to eliminate poor quality data.

  10. Conversational Markers of Constructive Discussions

    2016-01-01

    Group discussions are essential for organizing every aspect of modern life, from faculty meetings to senate debates, from grant review panels to papal conclaves. While costly in terms of time and organization effort, group discussions are commonly seen as a way of reaching better decisions compared to solutions that do not require coordination between the individuals (e.g. voting)---through discussion, the sum becomes greater than the parts. However, this assumption is not irrefutable: anecdotal evidence of wasteful discussions abounds, and in our own experiments we find that over 30% of discussions are unproductive. We propose a framework for analyzing conversational dynamics in order to determine whether a given task-oriented discussion is worth having or not. We exploit conversational patterns reflecting the flow of ideas and the balance between the participants, as well as their linguistic choices. We apply this framework to conversations naturally occurring in an online collaborative world exploration ga...

    Full Text Available Trabalhar com grupos juvenis de contextos interculturais e sociais distintos àquele do pesquisador exige cuidado e rigor no procedimento e na escolha dos métodos a serem utilizados para a coleta de dados, assim como uma preparação para o trabalho de campo. Mesmo assim, o pesquisador será confrontado com códigos de comunicação e estilos de vida que lhe são alheios. A decodificação desses sistemas exige uma espécie de imersão do pesquisador no meio pesquisado e um controle metodológico permanente do processo de interpretação, de forma a evitar vieses ou afirmações distorcidas sobre a realidade social de seus entrevistados. Nos últimos anos, o número de dissertações e teses sobre infância e juventude tem aumentado consideravelmente. No entanto, pela necessidade de entregarmos os trabalhos nos prazos estipulados ou por atribuirmos ao referencial teórico maior grau de importância, poucas vezes nos dedicamos a reconstruir a trajetória percorrida durante a fase de coleta e análise dos dados empíricos e a justificar as escolhas teórico-metodológicas realizadas.

    (1) How does the quality of life of patients with ADHD treated in an ambulatory care setting compare to that of other patient groups in child and adolescent psychiatry? (2) Can differences in the quality of life be demonstrated between patients with simple disorders of activity and attention and those with hyperkinetic conduct disorders? (3) How does the quality of life in these patient groups change over one year of treatment? The Inventory for the Assessment of Life Quality in Children and Adolescents (Inventar zur Untersuchung der Lebensqualität von Kindern und Jugendlichen, ILK) was applied to a sample of 726 patients derived from nine different outpatient practices for child and adolescent psychiatry. Among them were 196 patients with a simple disorder of activity and attention and 64 with a hyperkinetic conduct disorder. A comparison between these two groups was the main aim of the study. The mean age of the patients in the sample (all diagnoses) was 8.7 ± 3 years. The two groups of hyperkinetic patients made up 35% of the overall sample, and both of them showed a marked male predominance. The hyperkinetic patients tended to have lower quality-of-life scores than patients in the other diagnostic groups. Longitudinal observation revealed improvements in the quality of life across all patient groups, but the patients with hyperkinetic disorders (both groups) improved the least. The parents of the hyperkinetic patients, too, reported suffering greater stress because of their children's condition than the parents of children with other types of disorders. The ILK instrument has test-metrical qualities that render it usable and capable of holding its own among other, comparable instruments. It can be used to assess the quality of life of children with various diagnoses. Children with ADHD tend to have the least favorable quality-of-life scores, yet they do show some degree of improvement in their quality of life after a year of treatment.

    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

    2016-01-01

    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

  3. Discussion in Postsecondary Classrooms

    2013-11-01

    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

    通过对核设施关键人群组膳食调查方法局限性与现存问题的梳理,认为关键人群组膳食调查方法单一、调查内容不统一、关键人群组界定和认识有待于完善,提出如下建议:年龄组划分为婴儿(≤1岁)、儿童(2~6岁)、少年(7~17岁)和成人组(>17岁);膳食调查中粮食类细化到谷类、薯类和豆类,蔬菜至少细分为叶类和非叶类蔬菜;海产品细化到鱼类、甲壳类、软体类和藻类。在缺乏关键人群组食物消费量时,建议采用厂址半径5 km范围内膳食调查数据变化范围值的95%作为摄入率代替可能关键人群组的食物消费量。%By analyzing the dietary survey methods of key population groups of nuclear facilities, the paper argues that the current methods are too simple, the survey content is not consistent, and that the identification of key groups still need to be improved. The following suggestions are raised:the age groups are divided into infant (≤1 years), child (2~6 years old), teenager (7~17 years old) and adult group ( > 17 years);staple food are divided into frumentum, tubers and beans; vegetables are divided into leaf vegetables and non-leaf vegetables;and sea food are divided into fish, crustacean, mollusks and algae. In case of the absence of key groups’ diet amount data, it is suggested that 95% of the resulted amount range within 5 km of the facility is used.

    2011-01-01

    This reply is motivated by Sahay's comments on the paper published by Mendon??a Filho et al. (2010) dealing with the effect of concentration of an organic matter on optical maturity parameters. Four points were raised by Sahay: suggestion to use of chemical parameters to assess the effect of isolation, indication that suppression of vitrinite reflectance in liptinite-rich rocks was insufficiently addressed, discussion on the way to deal with the existence of multiple vitrinite populations in a dispersed organic matter, and contradictory explanation of results involving the influence of isolation procedure on fluorescence properties but no effect on vitrinite reflectance. The four points were separately addressed being the two first ones out of the scope of the paper. The existence of multiple vitrinite populations is a well-recognized problem whose importance in the results could be addressed because the participants provided individual records of vitrinite reflectance. These results indicated that election of different populations was not a major problem in the results. The influence of isolation procedure on the fluorescence spectra of alginite while the vitrinite reflectance remains unaltered is not considered contradictory because both parameters are measured on different components which may have a different response to the acid treatment. ?? 2011 Elsevier B.V.

    NIU Baogui; HE Zhengjun; SONG Biao; REN Jishun; XIAO Liwei

    2004-01-01

    A zircon U-Pb geochronological study on the volcanic rocks reveals that both of the Zhangjiakou and Yixian Formations, northern Hebei Province, are of the Early Cretaceous, with ages of 135-130 Ma and 129-120 Ma,respectively. It is pointed out that the ages of sedimentary basins and volcanism in the northern Hebei -western Liaoning area become younger from west to east, i. e. the volcanism of the Luanping Basin commenced at c. 135 Ma, the Luotuo Mount area of the Chengde Basin c. 130 Ma, and western Liaoning c. 128 Ma. With a correlation of geochronological stratigraphy and biostratigraphy, we deduce that the Xing'anling Group, which comprises the Great Hinggan Mountains volcanic rock belt in eastern China, is predominantly of the early-middle Early Cretaceous, while the Jiande and Shimaoshan Groups and their equivalents, which form the volcanic rock belt in the southeastern coast area of China, are of the mid-late Early Cretaceous, and both the Jehol and Jiande Biotas are of the Early Cretaceous, not Late Jurassic or Late Jurassic-Early Cretaceous. Combining the characteristics of the volcanic rocks and, in a large area, hiatus in the strata of the Late Jurassic or Late Jurassic-early Early Cretaceous between the formations mentioned above and the underlying sequences, we can make the conclusion that, in the Late Jurassic-early Early Cretaceous, the eastern China region was of high relief or plateau, where widespread post-orogenic volcanic series of the Early Cretaceous obviously became younger from inland in the west to continental margin in the east. This is not the result of an oceanward accretion of the subduction belt between the Paleo-Pacific ocean plate and the Asian continent, but rather reflects the extension feature, i.e. after the closure of the Paleo-Pacific ocean, the Paleo-Pacific ancient continent collided with the Asian continent and reached the peak of orogenesis, and then the compression waned and resulted in the retreating of the post

  11. Assessing Social Presence in Online Discussion Groups: A Replication Study

    Science.gov (United States)

    Hughes, Matthew; Ventura, Susie; Dando, Mark

    2007-01-01

    This paper argues that the emotional state of students' contributions need to be addressed in an online learning community. If feelings of fear, anger or isolation can lead to withdrawal or conflict then the potential for learning is reduced and a facilitator of an online course needs to manage these emotions at an early stage. Therefore, a…

  15. Repositories in an institutional context : Technical discussion Group 4

    CERN Document Server

    CERN. Geneva

    2007-01-01

    Repositories are starting to take their place within an institution¹s infrastructure, sitting alongside portals, course management systems, virtual research environments and others. But in considering how a repository can best serve an institution it is important to consider how this technology will integrate with existing systems, so that it doesn¹t become a standalone white elephant that is a nuisance to use. This breakout will consider the technical ways in which repositories can be presented as a system that is easy to use and interact with, from the searcher¹s, depositor¹s and administrator¹s perspectives. It will look at potential interaction through other institutional environments and seek to identify ways in which repositories can become a more integral part of the technical landscape. Bring along your examples of how repositories are being technically embedded within institutions to help share experience and ideas.

  18. Empowerment: a conceptual discussion.

    Science.gov (United States)

    Tengland, Per-Anders

    2008-06-01

    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    Meechamnan, Chutima; Fongkaew, Warunee; Chotibang, Jutamas; McGrath, Barbara Burns

    2014-03-01

    This qualitative study explored parents' and young adolescents' perceptions of communication related to sex and HIV/AIDS. Focus group discussions and group discussion were conducted among 67 adolescents and 30 parents. For the adolescents, group discussion using participatory activities was conducted, followed by five focus group discussions. Group discussions using participatory activities were conducted among parents. Thematic analysis indicated that the adolescents received inadequate information about sex and AIDS from their parents, whom they feared as providing negative judgment, and this represented a key barrier to such discussions. Their parents, on the other hand, reported that they believed their children were still too young to learn about and engage in sexual activities. The parents perceived barriers to communication included a lack of confidence and feelings of embarrassment. Nevertheless, they also recognized their important role in their child's sexual education. Collectively, these results draw attention to the need for a culturally appropriate program to strengthen parent-child communication skills for the topics of sex and HIV/AIDS. © 2013 Wiley Publishing Asia Pty Ltd.

    Wood, C.; Emin, D.; Gray, P. E.

    1985-01-01

    Knowledge of the thermal conductivity of boron carbide is necessary to evaluate its potential for high-temperature thermoelectric energy conversion applications. Measurements have been conducted of the thermal diffusivity of hot-pressed boron carbide BxC samples as a function of composition (x in the range from 4 to 9), temperature (300-1700 K), and temperature cycling. These data, in concert with density and specific-heat data, yield the thermal conductivities of these materials. The results are discussed in terms of a structural model that has been previously advanced to explain the electronic transport data. Some novel mechanisms for thermal conduction are briefly discussed.

    Full Text Available The major aim of this study was to investigate the effect of literary discussion on critical thinking. To this end, two classes (experimental and control groups were selected from College of Ferdowsi University. In both groups literature was used as supplementary homework. Students were supposed to read short stories and poems at home and present them in class. The students in the experimental group were discussing the materials in class and the students in the control group only memorized the texts and retold them. At the end of the term, the students were asked to take a questionnaire on critical thinking. The results demonstrated that there was a significant difference between means of two groups, implying that literary discussion can enhance critical thinking. Finally, results were discussed in the context of education in Iran and some suggestions were made.

    Steel structures in sea water and surface of hulls are deposited with such marine organisms as microorganisms, algae and shellfish. The deposition causes a large problem such as occurrence of abnormal local corrosion in the structures, and increase in cruising resistance in ocean vessels. The present study has introduced a simplified equation of estimation for current and potential distribution in parts coated with an electrically conductive film, and verified its reasonability by an experiment. The equation of estimation was introduced by following a model of current flow in the electrically conductive coating. The experiment has the conductive coating applied to the interior of a concrete water tank with a length of 10.8 m, a width of 5 m and a depth of 3 m to measure potential at different locations. The conductive coating was energized from copper foils attached on each applied face, whereas the current was applied to two faces between the conductive films as a pair among the four coating applied faces to measure potential in each location. A simulated calculation revealed that the potential range in the depth direction is made smaller if specific resistance of the conductive film is decreased, and made greater if increased. Effectiveness of the equation of estimation was verified by an experiment. This method has provided a prospect of achieving optimization of the specification for application of the conductive film. 2 refs., 7 figs.

    The setting, course, and results of a counseling and a therapeutic group for relatives of chronic aphasic patients are reviewed. Generally, providing and discussing information on the illness, its consequences, and medical and social services are greatly appreciated by group members. Counseling and group psychotherapy, as conducted by us, did not result in measurable improvements of relatives' perceptions of personal, social, and familial burdens. We assume, however, that group therapy does lead to more realistic attitudes toward burdensome and severely straining situations and may help with coping. Further research into psychotherapeutic strategies for relatives of disabled persons, who themselves suffer from psychological and social handicaps, is needed.

    Fabrication of porous silicon layers using the electrochemical technique followed by filling the nanopores with a group of conducting polymers is investigated. Our findings revealed that the deposition of polymer proceeds homogeneously inside the nanopores strating from the pore bottom and propagates into the outer surface. The polymerization process was conducted and controlled by the potentiostatic and galvanostatic modes with characteristic, defined polymerization stages. As-formed hybrid nanocomposites were characterized using different analytical techniques. Polypyrrole, polyaniline and polythiophene were tested in this study. By selective dissolution of porous silicon template, polymeric nanowires were obtained. The fabrication process, the electrochemical measurements and the porous silicon filling mechanism with polymer are thoroughly addressed and discussed (copyright 2011 WILEY-VCH Verlag GmbH and Co.

  6. Conduction and Turbulent Mixing in Galaxy Clusters

    CERN Document Server

    Narayan, R; Kim, Woong-Tae; Narayan, Ramesh

    2004-01-01

    We discuss hydrostatic models of galaxy clusters in which heat diffusion balances radiative cooling. We consider two different sources of diffusion, thermal conduction and turbulent mixing, parameterized by dimensionless coefficients, f and alpha_mix, respectively. Models with thermal conduction give reasonably good fits to the density and temperature profiles of several cooling flow clusters, but some clusters require unphysically large values of f>1. Models with turbulent mixing give good fits to all clusters, with reasonable values of alpha_mix ~ 0.01-0.03. Both types of models are found to be essentially stable to thermal perturbations. The mixing model reproduces the observed scalings of various cluster properties with temperature, and also explains the entropy floor seen in galaxy groups.

    2011-01-01

    Full Text Available This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated ''pariah'' groups. The (old five Mathieu groups make up the first, smallest order level. The seven groups related to the Leech lattice, including the three Conway groups, constitute the second level. The third and highest level contains the Monster group M, plus seven other related groups. Next a brief mention is made of the remaining six pariah groups, thus completing the 5+7+8+6=26 sporadic groups. The review ends up with a brief discussion of a few of physical applications of finite groups in physics, including a couple of recent examples which use sporadic groups.

    Pediatric heart transplant recipients are scarce and widely dispersed. Previous studies of adolescents in this population were limited to small homogenous samples. Although online focus groups are an emerging data collection method, its use in pediatric populations has not been fully realized. The purpose of this study was to explore the feasibility of using online focus groups with pediatric populations. Adolescents (aged 13 to 21 years) at least 6 months post-heart transplant and their parents were recruited from two children's hospitals. An online discussion forum (iTracks) was used to conduct asynchronous focus groups with separate parent and adolescent groups. Six parents and four adolescents participated in the discussions. iTracks provided a framework for conducting focus groups in dispersed populations. Access to the discussion transcripts enhanced data analysis and eliminated transcription costs. Overall, online discussion forums were a feasible and cost-effective option to conduct online focus groups in this pediatric population.

    The last few years have seen much research on girls with conduct disorder (CD). This article summarizes the gender-specific data regarding prevalence, differences with respect to symptomatology (e.g., subtypes of aggression, callous-unemotional (cu)-traits), and it presents data on the autonomic and neuroendocrine stress system as well as genetic, neurocognitive, and neuroimaging data. Differences in the impact of environmental factors on boys and girls for the development of CD are discussed. Taken together, the data indicate that there is great overlap in symptomatology, personality traits, and neurobiological aberrations in girls and boys with CD. Since fewer girls than boys exhibit CD symptomatology, further investigations on CD in girls might help to identify resilience factors that could improve future therapeutic interventions.

  10. Conductive dense hydrogen

    Eremets, M.; Troyan, I.

    2012-12-01

    Hydrogen at ambient pressures and low temperatures forms a molecular crystal which is expected to display metallic properties under megabar pressures. This metal is predicted to be superconducting with a very high critical temperature Tc of 200-400 K. The superconductor may potentially be recovered metastably at ambient pressures, and it may acquire a new quantum state as a metallic superfluid and a superconducting superfluid. Recent experiments performed at low temperatures T 220 GPa, new Raman modes arose, providing evidence for the transformation to a new opaque and electrically conductive phase IV. Above 260 GPa, in the next phase V, hydrogen reflected light well. Its resistance was nearly temperature-independent over a wide temperature range, down to 30 K, indicating that the hydrogen was metallic. Releasing the pressure induced the metallic phase to transform directly into molecular hydrogen with significant hysteresis at 200 GPa and 295 K. These data were published in our paper: M. I. Eremets and I. A. Troyan "Conductive dense hydrogen." Nature Materials 10: 927-931. We will present also new results on hydrogen: phase diagram with phases IV and V determined in P,T domain up to 300 GPa and 350 K. We will also discuss possible structures of phase IV based on our Raman and infrared measurements up to 300 GPa.

  11. Learning Styles and Online Discussion Posts

    Full Text Available Scholars have suggested models proposing a variety of learning styles for humans. Human Dynamics is one such model, and it has been suggested within its model that one style of learning is enhanced by discussion among learners. While this style of learning may be accomplished relatively easily in an on-campus person-to-person situation, it is not clear how a discussion mode (online posts of learning might be accomplished in an online format. A study of more than 9,000 posts from 240 students in 11 different online classes was conducted to determine whether differences in online discussion posts by individuals with different learning styles were evident. Results of the study suggest that discussion post activity, if managed with suitable rubrics and guiding principles, and augmented by appropriate modeling behavior, is an effective teaching mode for all dynamics, but seem to be a more successful learning mode for individuals of Physically Centered dynamics.

  13. Intraatrial conduction disturbances: vectorcardiographic patterns.

    Frank P loop vectorcardiograms were recorded in 30 normal subjects and in 40 patients who had intraatrial conduction disturbances alone or in association with cardiac disease. High magnification of the P loop (0.1 mv = 3 cm) permitted accurate measurement of the P loop duration, magnitude and direction. High-frequency recordings allowed optimal evaluation of the notches, bites and conduction delays in the PsE loop. Four vectorcardiographic patterns have been selected as counterparts of the four types of enlarged P waves seen in electrocardiograms of patients with atrial conduction disturbances. When intraatrial conduction disturbances coexisted with left atrial enlargment, the PsE loop was larger and smoother. The role of partial or complete block in the specific internodal or interatrial pathways is discussed. High magnification, high-frequency vectorcardiography of the P loop seems to be the best available method for determing a specific pattern of intraatrial conduction disturbance.

    The aim of this study was to analyze the cost utility of a group-based form of acceptance and commitment therapy (GACT) in patients with fibromyalgia (FM) compared with patients receiving recommended pharmacological treatment (RPT) or on a waiting list (WL). The data were derived from a previously published study, a randomized controlled trial that focused on clinical outcomes. Health economic outcomes included health-related quality of life and health care use at baseline and at 6-month follow-up using the EuroQoL and the Client Service Receipt Inventory, respectively. Analyses included quality-adjusted life years, direct and indirect cost differences, and incremental cost effectiveness ratios. A total of 156 FM patients were randomized (51 GACT, 52 RPT, 53 WL). GACT was related to significantly less direct costs over the 6-month study period compared with both control arms (GACT €824.2 ± 1,062.7 vs RPT €1,730.7 ± 1,656.8 vs WL €2,462.7 ± 2,822.0). Lower direct costs for GACT compared with RPT were due to lower costs from primary care visits and FM-related medications. The incremental cost effectiveness ratios were dominant in the completers' analysis and remained robust in the sensitivity analyses. In conclusion, acceptance and commitment therapy appears to be a cost-effective treatment compared with RPT in patients with FM. Decision-makers have to prioritize their budget on the treatment option that is the most cost effective for the management of a specific patient group. From government as well as health care perspectives, this study shows that a GACT is more cost effective than pharmacological treatment in management of FM. Copyright © 2017 American Pain Society.

  17. Dopants and defects in conductive oxide spinels

    We will discuss the effects of extrinsic and intrinsic imperfections (dopants and defects) in a group of conductive oxide materials related to Co3O4. Co3O4 is a spinel with Co2+ and Co3+ on tetrahedral and octahedral sites, respectively. Doping of Co3O4 with Zn and Ni represent two limiting cases: Zn2+ ions have a preference to occupy tetrahedral (Co2+) sites and are predicted to be unable to dope effectively; Ni2+ ions have a preference to occupy octahedral (Co3+) sites, so these atoms are expected to be efficient dopants. We found that substitution of Co3O4 spinel with up to 33 percent of Zn and Ni results in formation of ZnCo2O4 normal spinel and NiCo2O4 inverse spinel, and causes 100-fold and 1000-fold increases in conductivity, respectively, matching the predicted trend. Increase in Zn and Ni concentraion up to 40 percent cause phase separation of ZnO and NiO and leveling out of the conductivity. The conductivity decreases sharply above 50-60 percent Zn and Ni substitution level. Small differences with the theoretical predictions may be explained by non-equilibrium character of the thin film deposition process. This work was supported by the ``Center for Inverse Design'' EFRC of the Department of Energy.
