Lectins are multivalent proteins with the ability to recognize and bind diverse carbohydrate structures. The glyco -binding and diverse molecular structures observed in these protein classes make them a large and heterogeneous group with a wide range of biological activities in microorganisms, animals and plants. Lectins from plants and animals are commonly used in direct defense against pathogens and in immune regulation. This review focuses on sources of animal and plant lectins, describing their functional classification and tridimensional structures, relating these properties with biotechnological purposes, including antimicrobial activities. In summary, this work focuses on structural-functional elucidation of diverse lectin groups, shedding some light on host-pathogen interactions; it also examines their emergence as biotechnological tools through gene manipulation and development of new drugs.

Can ill-structured problems reveal beliefs about medical knowledge and knowing? A focus-group approach

2009-01-01

Background Epistemological beliefs (EB) are an individual's cognitions about knowledge and knowing. In several non-medical domains, EB have been found to contribute to the way individuals reason when faced with ill-structured problems (i.e. problems with no clear-cut, right or wrong solutions). Such problems are very common in medical practice. Determining whether EB are also influential in reasoning processes with regard to medical issues to which there is no straightforward answer, could have implications for medical education. This study focused on 2 research questions: 1. Can ill-structured problems be used to elicit general practice trainees' and trainers' EB? and 2. What are the views of general practice trainees and trainers about knowledge and how do they justify knowing? Methods 2 focus groups of trainees (n = 18) were convened on 3 occasions during their 1st year of postgraduate GP training. 2 groups of GP trainers (n = 11) met on one occasion. Based on the methodology of the Reflective Judgement Interview (RJI), participants were asked to comment on 11 ill-structured problems. The sessions were audio taped and transcribed and an adapted version of the RJI scoring rules was used to assess the trainees' reasoning about ill-structured problems. Results Participants made a number of statements illustrating their EB and their importance in clinical reasoning. The level of EB varied widely form one meeting to another and depending on the problem addressed. Overall, the EB expressed by trainees did not differ from those of trainers except on a particular ill-structured problem regarding shoulder pain. Conclusion The use of focus groups has entailed some difficulties in the interpretation of the results, but a number of preliminary conclusions can be drawn. Ill-structured medical problems can be used to elicit EB. Most trainees and trainers displayed pre-reflective and quasi-reflective EB. The way trainees and doctors view and justify knowledge are likely to be involved in medical reasoning processes. PMID:19775425

This study was undertaken to assess workplace hazards and protective practices among Hispanic men and women working post-harvest in asparagus, apple and pear packaging warehouses. Three focus groups were conducted in July 2003 with 25 workers (20 women, 5 men) recruited from communities in the Yakima Valley, Washington. Focus group content informed the design of an in-person structured interview administered to 50 additional warehouse workers from August to November 2006. Focus group participants reported difficult working conditions, exposure to chemicals, adverse health effects and use of work and home protective practices to minimize exposures for themselves and their families. Structured interview participants reported few workplace exposures to chemicals although many reported engaging in workplace and home protective practices. Findings from this research can direct initial efforts to determine if and how interventions for warehouse workers may be designed to protect against hazardous workplace exposures.

Therapist, Parent, and Youth Perspectives of Treatment Barriers to Family-Focused Community Outpatient Mental Health Services

PubMed Central

Jenkins, Melissa M.; Haine-Schlagel, Rachel

2012-01-01

This exploratory qualitative study describes treatment barriers to receiving family-focused child mental health services for youths with disruptive behavior problems from multiple perspectives. Data were collected during a series of focus groups and interviews, including: 4 therapist focus groups, 3 parent focus groups, and 10 youth semi-structured interviews. Therapist, parent, and youth stakeholder participants discussed perceived barriers to effective treatment, the problems with current child outpatient therapy, and desired changes (i.e., policy, intervention, etc.) to improve mental health services. Results indicate similar themes around treatment barriers and dissatisfaction with services within and across multiple stakeholder groups, including inadequate support and lack of family involvement; however, parents and therapists, in particular, identified different contributing factors to these barriers. Overall, stakeholders reported much frustration and dissatisfaction with current community-based outpatient child therapy services. Study findings can inform service provision, intervention development, and future research. PMID:24019737

The aims of this mixed-methods study were to assess tobacco treatment behaviors among residents and faculty in dental specialty postdoctoral programs and to explore factors in training and practice related to tobacco treatment education. Surveys and focus groups were conducted with a convenience sample of participants at three postdoctoral residency programs in New York City. Surveys assessed tobacco cessation training and behaviors. Focus groups explored barriers to implementing tobacco cessation treatment in educational settings. Data were collected between May and December 2013. Among the 160 faculty and residents identified as potentially eligible for the study, 60 were invited by program directors to participate, and 50 subsequently completed the survey and participated in a focus group (response rate of 31.3%). Survey results indicated high levels of asking patients about tobacco use and advising patients to quit. In contrast, specific tobacco cessation assistance and follow-up care occurred less frequently. There were statistically significant differences in tobacco cessation intervention across the specialties surveyed, but not between residents and faculty. Focus group comments were grouped into three broad areas: clinician factors, organizational support, and structural and contextual factors. Focus group results indicated that participants experienced significant organizational and structural barriers to learning about and providing tobacco treatment. Participants from each specialty indicated that multi-level barriers impeded their provision of evidence-based tobacco cessation interventions in postdoctoral educational settings. They suggested that didactic education should be reinforced by organizational- and systems-level changes to facilitate comprehensive tobacco education and effective cessation treatment in future dental practice.

The structural chemistry of actinide main-group metal materials provides the fundamental basis for the understanding of structural coordination chemistry and the formation of materials with desired or predicted structural features. The main-group metal building blocks, comprising sulfur-group, phosphorous-group, or silicon-group elements, have shown versatility in oxidation state, coordination, and bonding preferences. These building blocks have allowed us to elucidate a series of structures that are unique to the actinide elements, although we can find structural relationships to transition metal and 4f-element materials. In the past year, we investigated controlled metathesis and self-propagating reactions between actinide metal halides and alkali metalmore » salts of main-group metal chalcogenides such as K-P-S salts. Ternary plutonium thiophosphates have resulted from these reactions at low temperature in sealed ampules. we have also focused efforts to examine reactions of Th, U, and Pu halide salts with other alkali metal salts such as Na-Ge-S and Na-Si-Se and copper chloride to identify if self-propagating reactions may be used as a viable reaction to prepare new actinide materials and we prepared a series of U and Th copper chalcogenide materials. Magnetic measurements continued to be a focus of actinide materials prepared in our laboratory. We also contributed to the XANES work at Los Alamos by preparing materials for study and for comparison with environmental samples.« less

To identify the most relevant problems to be addressed in the multi-disciplinary care of patients with acute arthritis using focus groups of health professionals followed by a Delphi process. Focus group and Delphi methodology were applied. The focus groups were conducted at three specialist rheumatology hospital clinics in Germany, each group comprising rheumatologists, nurses, physiotherapists, occupational therapists, psychologists and social workers. The participants were asked to decide which categories of the International Classification of Functioning, Disability and Health (ICF) are relevant to the care of patients with acute inflammatory arthritis. The results from the focus groups were then followed by an anonymous Delphi process. Twenty-six health professionals participated in the 3 focus groups. 167 of the second-level ICF categories (63% of all second-level categories) were considered as relevant by the rheumatology health professionals. Items from all four components, Body Functions, Body Structures, Activities and Participation and Environmental Factors were represented. Agreement between focus groups and between different health professional groups was substantial for all components with the exception of Environmental Factors (Cohen's kappa 0.23). The involvement of experts from different health professions is a valuable tool to identify typical patient characteristics, expressed as distinct ICF categories, to aid in patient care in the acute rheumatology setting. Acute patient care cannot and should not be separated from ongoing long-term management.

2014-11-01

As interest grows in the diffusion of evidence-based interventions (EBIs), there is increasing concern about how to mitigate implementation challenges; this paper concerns adapting an EBI for homeless women. Complementing earlier focus groups with homeless women, homeless service providers (n = 32) were engaged in focus groups to assess capacity, needs, and barriers with implementation of EBIs. Deductive analyses of data led to the selection of four EBIs. Six consensus groups were then undertaken; three each with homeless women (n = 24) and homeless service providers (n = 21). The selected EBI was adapted and pretested with homeless women (n = 9) and service providers (n = 6). The structured consensus group process provided great utility and affirmed the expertise of homeless women and service providers as experts in their domain. Engaging providers in the selection process reduced the structural barriers within agencies as obstacles to diffusion.

The aim of this study is to determine opportunities and barriers regarding the management of overweight and obese children in daily practice, and to show the value of using focus groups when developing an action plan for childhood overweight management in a local context. Seven focus groups and four semi-structured interviews were conducted with 29 professionals from nine different care disciplines and 7 parents of overweight and obese children aged 4-19 years. After thorough analysis of the focus groups, issues concerning finding the most appropriate care and realising a long-term weight management in daily practice have become clear. Some examples of these issues are: lack of awareness, reluctance to discuss and refer, mutual cooperation, contradictory advice and expectations of treatment and lack of effective support strategies. Focus groups deliver important information on local issues that are important for the development and implementation of a childhood overweight management action plan. And, besides delivering necessary information, focus groups lead to an increased awareness and willingness to improve childhood overweight management in a local context. Copyright © 2012 S.

Literature on sickness presenteeism is emerging, but still little is known about employees who are never absent from work due to injuries or illness. Insight into the determinants and characteristics of such zero-absentees may provide clues for preventing sickness absence. To investigate the characteristics of zero-absentees, defined as employees without sickness absence over a period of 5 years. A mixed-method qualitative study comprising semi-structured interviews and focus groups for which Azjen and Fishbein's theory of planned behaviour was used as a framework. Zero-absentees working in hospital care were invited for semi-structured interviews until saturation was reached. The results of semi-structured interviews were validated in two focus groups. Of 1053 hospital employees, 47 were zero-absentees of whom 31 (66%) agreed to participate in the study. After 16 semi-structured interviews, no new insights or information were gathered from the interviews. The remaining 15 employees were invited to two (n = 8 and n = 7) focus groups. Personal attitudes and self-efficacy were more important in zero-absenteeism than social pressures of managers, colleagues or patients. Zero-absentees were found to be intrinsically motivated to try attending work when ill. In the present study population of hospital employees, we found indications that zero-absenteeism and sickness presenteeism might be different types of work attendance. Managers should realize that zero-absentees are driven by intrinsic motivation rather than social pressures to attend work.

Although Healthy Start case managers recognized the benefits of case management for facilitating optimal service delivery to women and their families, structural factors impact effective implementation. This study investigated case managers' views of 1) the structural challenges faced in implementing case management for program participants, and 2) possible strategies to enhance case management in medical home settings. Two focus groups were conducted separately with case managers from the four program service sites to gain insight into these issues noted above. Each group was co-facilitated by two evaluators using a previously developed semi-structured interview guide. The group discussions were audio recorded and the case managers' comments were transcribed verbatim. Transcripts were analyzed using thematic analysis, a deductive approach. Data were collected in 2013 and analyzed in 2015. Case managers are challenged by externalities (demographic shifts in target populations, poverty); contractual requirements (predefined catchment neighborhoods, caseload); limited support (client incentives, tailored training, and a high staff turnover rate); and logistic difficulties (organizational issues).

Consumer focus can spur group practice turnaround.

PubMed

Foreman, M S; Draper, A

2001-06-01

Many healthcare organizations have lost money on their employed group practices. The solution to this dilemma is not necessarily divestment of the group practices. Instead, some healthcare organizations should view their physicians as an asset. Healthcare organizations and physicians need to develop a new framework for their relationship to optimize their competitive advantage. Three guiding principles that will help accomplish this objective are to recast the healthcare organization-physician relationship to focus on the consumer, reconfigure the economic model to exceed consumer demands, and restructure the group practice to encourage fiscal and service excellence. In developing a new relationship framework, the stakeholders need to define the group practice's mission, strategic direction, composition, infrastructure, compensation model, and structure.

Stroke can cause physical and emotional problems affecting sexual well-being; healthcare professionals (HCPs) are often uncomfortable discussing this topic with patients. We explored the perspectives of HCPs and stroke survivors about barriers to discussing sexual well-being poststroke. A mixed methodology was employed. A postal survey of stroke survivors (n = 50), a focus group with HCPs on a stroke unit (n = 6), and a focus group with community-living stroke survivors (n = 6) were used in this study. Focus group data were analyzed thematically. No patient surveyed (60% response rate) had discussed sexual well-being with an HCP. Focus groups revealed barriers on multiple levels: structural, HCP, patient, and professional-patient interface. Healthcare professionals were poorly trained, adopted a passive role, and addressed sexual activity based on individual beliefs rather than having an agreed team approach. Relatively simple steps like inclusion in policy, training to empower HCPs, and the provision of written information for patients could help to improve practice.

2009-03-01

ASSISTIVE TECHNOLOGIES ARE RELATIVELY novel tools for research and daily care in long-term care (LTC) facilities that are faced with the burgeoning of the older adult population and dwindling staffing resources. The degree to which stakeholders in LTC facilities are receptive to the use of these technologies is poorly understood. Eighteen semi-structured focus groups and one interview were conducted with relevant groups of stakeholders at seven LTC facilities in southwestern Pennsylvania. Common themes identified across all focus groups centered on concerns for privacy, autonomy, cost, and safety associated with implementation of novel technologies. The relative importance of each theme varied by stakeholder group as well as the perceived severity of cognitive and/or physical disability. Our findings suggest that ethical issues are critical to acceptance of novel technologies by their end users, and that stakeholder groups are interdependent and require shared communication about the acceptance of these emerging technologies.

Abstract Background: Focus groups are often used to involve families as codesigners of weight management interventions. Focus groups, however, are seldom designed to elicit families' strengths and positive experiences. The purpose of this study was to describe the use of the Appreciative Inquiry process in the conduct of focus groups to engage families in the design of a weight management intervention for adolescents. Methods: A convenience sample of 44 parents (84% female; 82% minority) of adolescent children with a BMI ≥ 85th percentile, who were in the 6th–8th grade in a large urban school, participated in focus groups designed to elicit family-positive experiences and strengths regarding healthy living. A structured set of questions based on the Appreciative Inquiry process was used in the focus groups. Analyses consisted of the constant comparative method to generate themes. Results: Parent-positive perceptions regarding their family's healthy living habits were reflected in five themes: (1) Having healthy children is a joy; (2) Becoming healthy is a process; (3) Engaging in healthy habits is a family affair; (4) Good health habits can be achieved despite obstacles; and (5) School, community, and social factors contribute to their family's health habits. Parents generated ideas to improve their families' health. Conclusions: Focus groups based on the Appreciative Inquiry process were found to be a useful approach to discover features that are important to low-income, urban-living parents to include in an adolescent weight management program. Recommendations for designing and conducting focus groups based on the Appreciative Inquiry process are provided. PMID:28187267

Dispatches from the front: emergency medicine teachers' perceptions of competency-based education.

PubMed

Bandiera, Glen; Lendrum, David

2011-05-01

Controversy exists regarding the applicability of competency-based education during clinical rotations in emergency medicine (EM). Little has been written about the perceptions of front-line teachers regarding one such competency-based education paradigm, the CanMEDS framework. We undertook to determine 1) what perceptions exist among front-line teachers at two academic health science emergency departments (EDs) regarding the use of the CanMEDS roles to frame what residents should learn on ED rotations and 2) how those same teachers envision practically incorporating the CanMEDS roles into feedback provided to residents. Teachers at two sites volunteered for a semistructured focus group study. Focus groups were moderated by an experienced qualitative researcher, and verbatim transcriptions were coded by two independent reviewers. The codes were merged into final themes. The final focus group was used to further explore issues raised and test assumptions made in the preceding groups. In five focus groups involving 21 participants, the Medical Expert and Professional roles were seen as most relevant to an EM rotation, whereas the Health Advocate, Manager, Scholar, and Collaborator roles were least relevant. On further exploration, however, faculty identified highly relevant components of each role that they could envision teaching in an ED. Participants also felt that the framework helped highlight the breadth of physician competencies and provided structure for teaching and feedback. EM faculty find the CanMEDS framework helpful for structuring teaching and learning and that many elements of the roles, when defined, are feasible to integrate into a clinical rotation.

Abstract Background: Impulsivity is a complex trait often studied in substance abuse and overeating disorders, but the exact nature of impulsivity traits and their contribution to these disorders are still debated. Thus, understanding how to measure impulsivity is essential for comprehending addictive behaviors. Identify unique impulsivity traits specific to substance use and overeating. Impulsive Sensation Seeking (ImpSS) and Barratt's Impulsivity scales (BIS) Scales were analyzed with a non-parametric factor analytic technique (discriminant correspondence analysis) to identify group-specific traits on 297 individuals from five groups: Marijuana (n = 88), Nicotine (n = 82), Overeaters (n = 27), Marijuauna + Nicotine (n = 63), and CONTROLs (n = 37). A significant overall factor structure revealed three components of impulsivity that explained respectively 50.19% (pperm < 0.0005), 24.18% (pperm < 0.0005), and 15.98% (pperm < 0.0005) of the variance. All groups were significantly different from one another. When analyzed together, the BIS and ImpSS produce a multi-factorial structure that identified the impulsivity traits specific to these groups. The group specific traits are (1) CONTROL: low impulse, avoids thrill-seeking behaviors; (2) Marijuana: seeks mild sensation, is focused and attentive; (3) Marijuana + Nicotine: pursues thrill-seeking, lacks focus and attention; (4) Nicotine: lacks focus and planning; (5) Overeating: lacks focus, but plans (short and long term). Our results reveal impulsivity traits specific to each group. This may provide better criteria to define spectrums and trajectories - instead of categories - of symptoms for substance use and eating disorders. Defining symptomatic spectrums could be an important step forward in diagnostic strategies.

Legal expert opinions are a crucial instrument of professional self-control in medicine. To give impulses for further development, focus groups were initiated to reflect upon the perspective of legal dental experts. 5 focus group discussions on the topic "Professionalization of legal dental experts" were conducted. A total of 32 experienced legal dental experts participated in the discussions. The results were evaluated by qualitative content analysis. A catalogue of 68 ideas was generated for improvement and divided into 15 categories. Among these were periodic quality circles, interprofessional exchange, supervision of novices and periodic feedback for legal dental experts and dentists. Self-reflection can be included as an instrument for quality improvement of legal dental expert opinions. © Georg Thieme Verlag KG Stuttgart · New York.

Younger adults are more likely to smoke and less likely to seek treatment than older smokers. They are also frequent users of communication technology. In the current study, we conducted focus groups to obtain feedback about preferences for a text message-based smoking cessation program from potential users. Participants (N = 21, M age = 25.6 years, age range = 20-33 years) were current or recently quit smokers (M cigarettes/day = 12.8) who used text messaging. Participants completed questionnaires and participated in a 2-hour focus group. Focus groups were conducted using an a priori semistructured interview guide to promote discussion of the content and functionality of the intervention. Major themes from analysis of the focus groups included support for the acceptability of a text-based cessation program, suggestions for a more technologically broad-based program, and adjustments to the program structure. Participants recommended including social networking functions, user control of program output through an online profile, and text message features to promote interaction with the system. Interestingly, many participants suggested the program should begin on individuals' identified quit day, challenging the procedures used in most cessation programs, which begin by preparing participants for a future quit date. Overall, younger adult smokers appear to be interested in participating in a smoking cessation program that uses text messages and web-based elements. Qualitative feedback regarding the perceived optimal features and structure of a technology-based intervention challenged traditional methods of implementing smoking cessation interventions and will inform the development of future programs.

2014-01-01

Public health HIV prevention efforts have begun to focus on addressing social and structural factors contributing to HIV risk, such as unstable housing, unemployment and access to healthcare. With a limited body of evidence-based structural interventions for HIV, communities tasked with developing structural changes need a defined process to clarify their purpose and goals. This paper describes the adaptations made to a coalition development model with the purpose of improving the start-up phase for a second group of coalitions. Modifications focused on preparing coalitions to more efficiently apply structural change concepts to their strategic planning activities, create more objectives that met study goals, and enhance coalition procedures, such as building distributed coalition leadership, to better support the mobilization process. We report on primary modifications to the process, findings for the coalitions and recommendations for public health practitioners that are seeking to start a similar coalition. PMID:26785397

Health services researchers focus on the players, structures and impact of health care in "real life". They investigate how social aspects, financing, organizational structures, technologies and personal attitudes affect the process and outcomes of health care. Qualitative research methods are used here, which address how people act according to their unique living conditions (outside the context of experimental studies). Different methods of debriefing groups are essential for qualitative health services research. In 2 subsequent articles, we aim to outline the diverse facets and possible range of implementation of the above-mentioned methods, in order to highlight the potential of debriefing groups in health services research (focus groups or group discussions) using these methods. In the current article, we would like to encourage researchers to reflect on relevant topics such as the selection of an appropriate method, the planning and undertaking of investigations including sampling methods, and questions regarding ethics and privacy. A follow-up article (in preparation) will deal with theoretical considerations of the term "group", as well as with the process of moderating discussions, methods of analyzing data and (qualitative) online research. © Georg Thieme Verlag KG Stuttgart · New York.

The group II intron maturase: a reverse transcriptase and splicing factor go hand in hand.

PubMed

Zhao, Chen; Pyle, Anna Marie

2017-12-01

The splicing of group II introns in vivo requires the assistance of a multifunctional intron encoded protein (IEP, or maturase). Each IEP is also a reverse-transcriptase enzyme that enables group II introns to behave as mobile genetic elements. During splicing or retro-transposition, each group II intron forms a tight, specific complex with its own encoded IEP, resulting in a highly reactive holoenzyme. This review focuses on the structural basis for IEP function, as revealed by recent crystal structures of an IEP reverse transcriptase domain and cryo-EM structures of an IEP-intron complex. These structures explain how the same IEP scaffold is utilized for intron recognition, splicing and reverse transcription, while providing a physical basis for understanding the evolutionary transformation of the IEP into the eukaryotic splicing factor Prp8.

We conducted a mixed-methods study-- the focus of this article--to understand how workers in long-term care facilities experienced working conditions. We surveyed unionized care workers in Ontario (n = 917); we also surveyed workers in three Canadian provinces (n = 948) and four Scandinavian countries (n = 1,625). In post-survey focus groups, we presented respondents with survey questions and descriptive statistical findings, and asked them: "Does this reflect your experience?" Workers reported time pressures and the frequency of experiences of physical violence and unwanted sexual attention, as we explain. We discuss how iteratively mixing qualitative and quantitative methods to triangulate survey and focus group results led to expected data convergence and to unexpected data divergence that revealed a normalized culture of structural violence in long-term care facilities. We discuss how the finding of structural violence emerged and also the deeper meaning, context, and insights resulting from our combined methods.

Learning science through talk: A case study of middle school students engaged in collaborative group investigation

NASA Astrophysics Data System (ADS)

Zinicola, Debra Ann

Reformers call for change in how science is taught in schools by shifting the focus towards conceptual understanding for all students. Constructivist learning is being promoted through the dissemination of National and State Science Standards that recommend group learning practices in science classrooms. This study examined the science learning and interactions, using case study methodology, of one collaborative group of 4 students in an urban middle school. Data on science talk and social interaction were collected over 9 weeks through 12 science problem solving sessions. To determine student learning through peer interaction, varied group structures were implemented, and students reflected on the group learning experience. Data included: field notes, cognitive and reflective journals, audiotapes and videotapes of student talk, and audiotapes of group interviews. Journal data were analyzed quantitatively and all other data was transcribed into The Ethnograph database for qualitative analysis. The data record was organized into social and cognitive domains and coded with respect to interaction patterns to show how group members experienced the social construction of science concepts. The most significant finding was that all students learned as a result of 12 talk sessions as evidenced by pre- and post-conceptual change scores. Interactions that promoted learning involved students connecting their thoughts, rephrasing, and challenging ideas. The role structure was only used by students about 15% of the time, but it started the talk with a science focus, created awareness of scientific methods, and created an awareness of equitable member participation. Students offered more spontaneous, explanatory talk when the role structure was relaxed, but did not engage in as much scientific writing. They said the role structure was important for helping them know what to do in the talk but they no longer needed it after a time. Gender bias, status, and early adolescent developmental factors influenced many of the group's interactions. Recommendations are that: collaborative group problem solving be used frequently to promote conceptual change, teachers begin with a role structure to guide interactions, create heterogeneous groups, keep the same students together for a significant period of time, and monitor, guide, and teach during group learning sessions.

To explore opinions of why clients use, value and continue to seek massage therapy as a healthcare option. Telephone focus group methodology was used. Current and repeat users (n = 19) of either relaxation, remedial or sports massage therapy services participated in three telephone focus groups. Audiotaped semi-structured interviews were conducted. Telephone focus group with massage clients from provincial and urban localities in New Zealand. Summary of reported themes of the massage experience and suggested drivers for return to, or continuing with massage therapy. Data were transcribed, categorised (NVivo7) and thematically analysed using the general inductive approach. Key drivers for return to, or continuing with, massage therapy were: positive outcomes, expectations of goals being met, a regular appointment and the massage therapy culture. Massage therapy is perceived and valued as a personalised, holistic and hands-on approach to health management, which focuses on enhancing relaxation in conjunction with effective touch, within a positive client-therapist relationship and a pleasant non-rushed environment. Massage therapy as a health service is result and client driven but is reinforced by the culture of the experience.

Group affiliation in self-management: support or threat to identity?

PubMed

Bossy, Dagmara; Knutsen, Ingrid Ruud; Rogers, Anne; Foss, Christina

2017-02-01

Self-management is considered important in chronic illness, and contemporary health policy recommends participation in support groups for individuals with chronic conditions. Although withdrawal from or non-participation in support groups is an important problem, there is limited knowledge about individuals' own motivation for participation in or withdrawal from self-management support groups. To investigate how individuals with type 2 diabetes perceive participation in group-based self-management support. This is a qualitative focus group study using a semi-structured interview guide. Sixteen participants diagnosed with type 2 diabetes were included in the study. Individuals with and without group affiliations were mixed in three focus groups to trigger discussions. In the analysis, reoccurring themes of engagement and discussions between participants were focused within a theoretical frame of institutional logic. The focus groups are seen as social spaces where participants construct identity. Both participation and non-participation in group-based self-management support are associated with dealing with the stigma of having type 2 diabetes. Negotiations contribute to constructing an illness dignity as a response to the logic of moral responsibility for the disease. Contemporary policy contributes to societal understandings of individuals with type 2 diabetes as morally inadequate. Our study shows that group-based self-management support may counteract blame and contribute in negotiations of identity for individuals with type 2 diabetes. This mechanism makes participation in groups beneficial for some but stigma inducing for others. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

Factor structure of the Bulimia Test--Revised in college women from four ethnic groups.

2006-07-01

The factor structure of the Bulimia Test--Revised (BULIT-R) was investigated using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). The sample consisted of 2,671 female college students (African American, Asian American, Caucasian American, and Latino American). Reliability coefficients were excellent across groups. African Americans scored significantly lower on the BULIT-R than Caucasian Americans. Across groups, CFA and EFA results suggest a six-factor solution is most appropriate. Consistent across groups were factors representing bingeing, body image, purging, and extreme weight loss behaviors, while few differences were observed across groups. These findings suggest that the measure is reliable and valid for use with diverse ethnic groups. Future research should focus on culturally salient psychological correlates of disordered eating in diverse ethnic groups.

Regular exercise can have positive effects on both the physical and mental health of individuals with schizophrenia. However, deficits in cognition, perception, affect, and volition make it especially difficult for people with schizophrenia to plan and follow through with their exercising intentions, as indicated by poor attendance and high drop-out rates in prior studies. Mental Contrasting and Implementation Intentions (MCII) is a well-established strategy to support the enactment of intended actions. This pilot study tests whether MCII helps people with schizophrenia in highly structured or autonomy-focused clinical hospital settings to translate their exercising intentions into action. Thirty-six inpatients (eleven women) with a mean age of 30.89 years (SD = 11.41) diagnosed with schizophrenia spectrum disorders from specialized highly structured or autonomy-focused wards were randomly assigned to two intervention groups. In the equal contact goal intention control condition, patients read an informative text about physical activity; they then set and wrote down the goal to attend jogging sessions. In the MCII experimental condition, patients read the same informative text and then worked through the MCII strategy. We hypothesized that MCII would increase attendance and persistence relative to the control condition over the course of four weeks and this will be especially be the case when applied in an autonomy-focused setting compared to when applied in a highly structured setting. When applied in autonomy-focused settings, MCII increased attendance and persistence in jogging group sessions relative to the control condition. In the highly structured setting, no differences between conditions were found, most likely due to a ceiling effect. These results remained even when adjusting for group differences in the pre-intervention scores for the control variables depression (BDI), physical activity (IPAQ), weight (BMI), age, and education. Whereas commitment and physical activity apart from the jogging sessions remained stable over the course of the treatment, depression and negative symptoms were reduced. There were no differences in pre-post treatment changes between intervention groups. The intervention in the present study provides initial support for the hypothesis that MCII helps patients to translate their exercising intentions into real-life behavior even in autonomously-focused settings without social control.

The Health Regulatory Focus Scale (HRFS) is a short scale which measures an individual's prevention and promotion focus in a health-specific context. The main objective of this study was to examine the psychometric properties of the newly translated German version of the HRFS. Reliability and item characteristics were found to be satisfactory. Validity of both subscales toward other psychological constructs including behavioral approach and avoidance, core self-evaluations, optimism, pessimism, neuroticism, as well as several measures of physical and mental health was shown. In addition, invariance of the measure across age and gender groups was shown. Exploratory as well as confirmatory factor analyses clearly indicated a two-factorial structure with a moderate correlation between the two latent constructs. Differences in health promotion and prevention focus between socio-demographic groups are discussed. The HRFS is found to be a valid and reliable instrument for the assessment of regulatory focus in health-related environments. PMID:29184528

The Role of Content Knowledge in Ill-Structured Problem Solving for High School Physics Students

NASA Astrophysics Data System (ADS)

Milbourne, Jeff; Wiebe, Eric

2018-02-01

While Physics Education Research has a rich tradition of problem-solving scholarship, most of the work has focused on more traditional, well-defined problems. Less work has been done with ill-structured problems, problems that are better aligned with the engineering and design-based scenarios promoted by the Next Generation Science Standards. This study explored the relationship between physics content knowledge and ill-structured problem solving for two groups of high school students with different levels of content knowledge. Both groups of students completed an ill-structured problem set, using a talk-aloud procedure to narrate their thought process as they worked. Analysis of the data focused on identifying students' solution pathways, as well as the obstacles that prevented them from reaching "reasonable" solutions. Students with more content knowledge were more successful reaching reasonable solutions for each of the problems, experiencing fewer obstacles. These students also employed a greater variety of solution pathways than those with less content knowledge. Results suggest that a student's solution pathway choice may depend on how she perceives the problem.

Tailored strategies to implement evidence-based practice can be generated in several ways. In this study, we explored the usefulness of group interviews for generating these strategies, focused on improving healthcare for patients with chronic diseases. Participants included at least four categories of stakeholders (researchers, quality officers, health professionals, and external stakeholders) in five countries. Interviews comprised brainstorming followed by a structured interview and focused on different chronic conditions in each country. We compared the numbers and types of strategies between stakeholder categories and between interview phases. We also determined which strategies were actually used in tailored intervention programs. In total, 127 individuals participated in 25 group interviews across five countries. Brainstorming generated 8 to 120 strategies per group; structured interviews added 0 to 55 strategies. Healthcare professionals and researchers provided the largest numbers of strategies. The type of strategies for improving healthcare practice did not differ systematically between stakeholder groups in four of the five countries. In three out of five countries, all components of the chosen intervention programs were mentioned by the group of researchers. Group interviews with different stakeholder categories produced many strategies for tailored implementation of evidence-based practice, of which the content was largely similar across stakeholder categories.

Teachers' Organization of Participation Structures for Teaching Science with Computer Technology

NASA Astrophysics Data System (ADS)

Subramaniam, Karthigeyan

2016-08-01

This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher-students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants' instruction with computer technology was ( Teacher) initiation-( Student and Teacher) response sequences-( Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers' learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers' own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.

Background The quality of doctor-patient communication has a major impact on the quality of medical care. Communication guidelines define best practices for doctor patient communication and are therefore an important tool for improving communication. However, adherence to communication guidelines remains low, despite doctors participating in intensive communication skill training. Implementation research shows that adherence is higher for guidelines in general that are user centred and feasible, which implies that they are consistent with users' opinions, tap into users' existing skills and fit into existing routines. Developers of communication guidelines seem to have been somewhat negligent with regard to user preferences and guideline feasibility. In order to promote the development of user centred and practicable communication guidelines, we elicited user preferences and identified which guideline characteristics facilitate or impede guideline use. Methods Seven focus group interviews were conducted with experienced GPs, communication trainers (GPs and behavioural scientists) and communication learners (GP trainees and medical students) and three focus group interviews with groups of GP trainees only. All interviews were transcribed and analysed qualitatively. Results The participants identified more impeding guideline characteristics than facilitating ones. The most important impeding characteristic was that guidelines do not easily fit into GPs' day-to-day practice. This is due to rigidity and inefficiency of communication guidelines and erroneous assumptions underpinning guideline development. The most important facilitating characteristic was guideline structure. Guidelines that were structured in distinct phases helped users to remain in control of consultations, which was especially useful in complicated consultations. Conclusion Although communication guidelines are generally considered useful, especially for structuring consultations, their usefulness is impaired by lack of flexibility and applicability to practice routines. User centred and feasible guidelines should combine the advantages of helping doctors to structure consultations with flexibility to tailor communication strategies to specific contexts and situations.

Numerous biological activities including antioxidant, antitumor, anti-inflammation, and antivirus of the natural product curcumin were reported. However, the clinical application of it was significantly limited by its instability, poor solubility, less body absorbing, and low bioavailability. This review focuses on the structure modification and antioxidant activity evaluation of curcumin. To study the structure-activity relationship (SAR), five series of curcumin analogs were synthesized and their antioxidant activity were evaluated in vitro. The results showed that electron-donating groups, especially the phenolic hydroxyl group are an essential component to improve the antioxidant activity.

Objective To adapt marketing approaches in a health services environment. Methods Researchers and advertising professionals partnered in developing advertising-style messages designed to activate patients pre-identified as having chronic kidney disease to ask providers about recommended medications. We assessed feasibility of the development process by evaluating partnership structure, costs, and timeframe. We tested messages with patients and providers using preliminary surveys to refine initial messages and subsequent focus groups to identify the most persuasive ones. Results The partnership achieved an efficient structure, $14,550 total costs, and 4-month timeframe. The advertising team developed 11 initial messages. The research team conducted surveys and focus groups with a total of 13 patients and 8 providers to identify three messages as most activating. Focus group themes suggested the general approach of using advertising-style messages was acceptable if it supported patient-provider relationships and had a credible evidence base. Individual messages were more motivating if they elicited personal identification with imagery, particular emotions, active patient role, and message clarity. Conclusion We demonstrated feasibility of a research-advertising partnership and acceptability and likely impact of advertising-style messages on patient medication-seeking behavior. Practice Implications Healthcare systems may want to replicate our adaptation of marketing approaches to patients with chronic conditions. PMID:25913245

The study expands research on accessibility, comparing compliance scores of aquatic facilities in North Texas built before the 1991 Title III Americans with Disabilities Act Accessibility Guidelines (ADAAG) with facilities built after the 1991 ADAAG and the proposed 2002 supplement. A quasi-experimental design directed the selection of 52 facilities where measurements were taken to determine compliance with ADAAG and the supplement. A focus group provided insight into interpreting which features functioned as barriers or constraints to participation. Metropolitan statistical area in North Texas. A total of 52 aquatic facilities and 12 focus group participants (University of North Texas institutional review board 07-283). ADA aquatic facility compliance instrument. Frequency, ratios. No facilities were 100% ADA compliant overall, although some facilities were 100% compliant with specific structural domains. Women's restrooms rated lowest (average = 55%), and men's restrooms received the second lowest rating (average = 64%). Focus group results indicated that improperly designed restrooms and pool entries are primary barriers to participation. The findings support a need for stronger enforcement of policies that improve accessibility of facilities. Architectural reviews and construction practices need to be improved. The structural barriers and constraints identified can be limiting factors in efforts aimed at increasing physical activity among individuals with disabilities and individuals with physical limitations.

The purpose is to describe the development and validation of a tool to measure the degree of past food insecurity in an immigrant US population. Focus group discussions and a structured interview. As a first step, focus group discussions were conducted among immigrant Latino mothers. Based on these discussions, an 8-item tool was developed and pilot-tested in a convenience sample of mothers. California. Twenty-two low-income Latino mothers with children, ages 4 to 5 years, in the focus groups and 85 low-income Latino and white mothers of young children in the structured interviews. Constant comparative analysis, Cronbach alpha, Spearman correlations, Chi-square, and Kruskal-Wallis test. Internal consistency of the remaining 7 items was good (Cronbach alpha = 0.84). Evidence of convergent validity included significant correlations between past food insecurity and maternal education (r = -0.45, p < .0001), crowding in the mother's childhood household (r = +0.30, p < .006), and past food insufficiency (r = +0.74, p < .0001). Foreign-born Latino mothers reported significantly greater levels of past food insecurity than US-born mothers, demonstrating discriminant validity (p < .01). This tool may be useful to determine how past deprivation influences current food choices and other nutrition-related behaviors in low-income Latino immigrants.

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

Public housing residents have a high risk of chronic disease, which may be related to neighborhood environmental factors. Our objective was to understand how public housing residents perceive that the social and built environments might influence their health and wellbeing. We conducted focus groups of residents from a low-income public housing community in Baltimore, MD to assess their perceptions of health and neighborhood attributes, resources, and social structure. Focus groups were audio-recorded and transcribed verbatim. Two investigators independently coded transcripts for thematic content using editing style analysis technique. Twenty-eight residents participated in six focus groups. All were African American and the majority were women. Most had lived in public housing for more than 5 years. We identified four themes: public housing's unhealthy physical environment limits health and wellbeing, the city environment limits opportunities for healthy lifestyle choices, lack of trust in relationships contributes to social isolation, and increased neighborhood social capital could improve wellbeing. Changes in housing and city policies might lead to improved environmental health conditions for public housing residents. Policymakers and researchers may consider promoting community cohesiveness to attempt to empower residents in facilitating neighborhood change.

Annotated bibliography of structural equation modelling: technical work.

Researchers must be familiar with a variety of source literature to facilitate the informed use of structural equation modelling. Knowledge can be acquired through the study of an expanding literature found in a diverse set of publishing forums. We propose that structural equation modelling publications can be roughly classified into two groups: (a) technical and (b) substantive applications. Technical materials focus on the procedures rather than substantive conclusions derived from applications. The focus of this article is the former category; included are foundational/major contributions, minor contributions, critical and evaluative reviews, integrations, simulations and computer applications, precursor and historical material, and pedagogical textbooks. After a brief introduction, we annotate 294 articles in the technical category dating back to Sewall Wright (1921).

Professionals within the mental health services face many ethical dilemmas and challenging situations regarding the use of coercion. The purpose of this study was to evaluate the significance of participating in systematic ethics reflection groups focusing on ethical challenges related to coercion. In 2013 and 2014, 20 focus group interviews with 127 participants were conducted. The interviews were tape recorded and transcribed verbatim. The analysis is inspired by the concept of 'bricolage' which means our approach was inductive. Most participants report positive experiences with participating in ethics reflection groups: A systematic and well-structured approach to discuss ethical challenges, increased consciousness of formal and informal coercion, a possibility to challenge problematic concepts, attitudes and practices, improved professional competence and confidence, greater trust within the team, more constructive disagreement and room for internal critique, less judgmental reactions and more reasoned approaches, and identification of potential for improvement and alternative courses of action. On several wards, the participation of psychiatrists and psychologists in the reflection groups was missing. The impact of the perceived lack of safety in reflection groups should not be underestimated. Sometimes the method for ethics reflection was utilised in a rigid way. Direct involvement of patients and family was missing. This focus group study indicates the potential of ethics reflection groups to create a moral space in the workplace that promotes critical, reflective and collaborative moral deliberations. Future research, with other designs and methodologies, is needed to further investigate the impact of ethics reflection groups on improving health care practices.

The influence of the structure and culture of medical group practices on prescription drug errors.

2005-08-01

This project was designed to identify the magnitude of prescription drug errors in medical group practices and to explore the influence of the practice structure and culture on those error rates. Seventy-eight practices serving an upper Midwest managed care (Care Plus) plan during 2001 were included in the study. Using Care Plus claims data, prescription drug error rates were calculated at the enrollee level and then were aggregated to the group practice that each enrollee selected to provide and manage their care. Practice structure and culture data were obtained from surveys of the practices. Data were analyzed using multivariate regression. Both the culture and the structure of these group practices appear to influence prescription drug error rates. Seeing more patients per clinic hour, more prescriptions per patient, and being cared for in a rural clinic were all strongly associated with more errors. Conversely, having a case manager program is strongly related to fewer errors in all of our analyses. The culture of the practices clearly influences error rates, but the findings are mixed. Practices with cohesive cultures have lower error rates but, contrary to our hypothesis, cultures that value physician autonomy and individuality also have lower error rates than those with a more organizational orientation. Our study supports the contention that there are a substantial number of prescription drug errors in the ambulatory care sector. Even by the strictest definition, there were about 13 errors per 100 prescriptions for Care Plus patients in these group practices during 2001. Our study demonstrates that the structure of medical group practices influences prescription drug error rates. In some cases, this appears to be a direct relationship, such as the effects of having a case manager program on fewer drug errors, but in other cases the effect appears to be indirect through the improvement of drug prescribing practices. An important aspect of this study is that it provides insights into the relationships of the structure and culture of medical group practices and prescription drug errors and provides direction for future research. Research focused on the factors influencing the high error rates in rural areas and how the interaction of practice structural and cultural attributes influence error rates would add important insights into our findings. For medical practice directors, our data show that they should focus on patient care coordination to reduce errors.

Sámi youth health, the role of climate change, and unique health-seeking behaviour.

The goal of this cross-sectional qualitative study was to assess the impact of climate change on Sámi youth health, health care access, and health-seeking behaviour. Indigenous research methodology served as the basis of the investigation which utilised focus groups of youths and one-on-one interviews of adult community leaders using a semi-structured, open-ended questions. The results of the focus groups and interviews were then analysed to identify trends. We found that Sámi youth mostly associate the implications of climate change to their culture andcultural practices rather than the historical influence the environment had on Sámi health. They also take part in unique health-seeking behaviour by utilising both traditional and Western medicine simultaneously but without interaction due to social and structural factors. Our findings suggest that the health of Sámi teens is not tied to the environment directly, but through cultural activities.

Patients with borderline personality disorder (BPD) show various psychopathological symptoms and suffer especially from disturbance in their identity. The purpose of the study was to investigate changes-particularly in affective BPD symptoms and identity diffusion-during a structured, disorder-specific inpatient treatment (DST) that combined a psychodynamic transference-focused psychotherapy approach with modules of dialectical behavioural skills training. In a prospective, two-group comparison trial, 44 patients with BPD were assessed with questionnaires addressing identity diffusion and state, as well as trait affective psychopathology, before and after 12 weeks of inpatient treatment. Thirty-two patients received DST, whereas 12 patients were given inpatient treatment-as-usual (TAU). The patients were allocated in a non-random procedure for two groups, in order of admission and availability of treatment options in the DST unit. In the pre-post-comparison, the DST group showed a significant decrease in identity diffusion (p < 0.001) and improvements in instability of the image of self and others (p < 0.008), as well as in pathological (trait and state) symptoms. However, there was no significant improvement in the TAU group. After a 12-week inpatient treatment, the findings indicate significant improvements in the DST group in typical affective borderline symptomatology and in the personality structure feature of identity diffusion. This highlights the significance of a short-term specific inpatient therapy for BPD. A structured, disorder-specific inpatient treatment of patients diagnosed with borderline personality disorder (BPD) combined a psychodynamic transference-focused psychotherapy treatment approach (focusing on pathological features in personality organization, particularly on non-integrated images of self and others) with modules of dialectical behavioural skills training. This treatment is associated with a decrease in identity diffusion of these patients after 12 weeks of treatment. The treatment is also related to a significant decrease in borderline typical psychopathological symptoms such as depressive symptoms, as well as an improvement in state anger. The outcomes of this structured, disorder-specific inpatient treatment of severely ill BPD patients indicated the relevance of intensive short-term inpatient psychotherapy in terms of psychopathological improvements as well as initial changes in structural personality organization.

Eklund, Wakako; Kenner, Carole

2015-12-01

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

Consumer involvement in guideline development is advocated, but minimal participation, such as a nominated consumer representative on a guideline working group, can inhibit their decision-making power and contribution. Little is known about how to involve consumers more effectively in guideline development. To describe a targeted approach for involving consumers actively in guideline development, by focusing on topic and outcome selection, and to discuss the impact on content and structure of the final guideline. Descriptive study. Patients and carers (n = 24) from a tertiary hospital in Sydney attended three structured peer-facilitated workshops to complete group-based exercises on topic and outcome selection for guidelines for early stage chronic kidney disease. These workshops were run in parallel with the guideline-writing group. For each exercise, participants formed small groups and facilitated their own discussion, recorded their responses and presented them to the wider group. The topics and outcomes identified were fed back to the guideline writers. The participants actively engaged in the workshop discussions and articulated topics and outcomes they perceived should be included in clinical guidelines. Four main changes to guideline-related outputs were observed. A new guideline subtopic was introduced, guidelines were consumer-endorsed, guideline recommendations and suggestions for clinical care were augmented with consumer-focused issues, and plain English guidelines were developed. Consumer workshops in parallel and feeding into guideline development can be a feasible and effective approach for active consumer contribution. This process can inform the development of both consumer-focused guidelines for clinicians and specific versions for consumers. © 2011 Blackwell Publishing Ltd.

Social structure affects mating competition in a damselfish

The strength of mating competition and sexual selection varies over space and time in many animals. Such variation is typically driven by ecological and demographic factors, including adult sex ratio and consequent availability of mates. The spatial scale at which demographic factors affect mating competition and sexual selection may vary but is not often investigated. Here, we analyse variation in size and sex ratio of social groups, and how group structure affects mating competition, in the site-attached damselfish Chrysiptera cyanea. Site-attached reef fishes are known to show extensive intraspecific variation in social structure. Previous work has focused on species for which the size and dynamics of social groups are constrained by habitat, whereas species with group structure unconstrained by habitat have received little attention. Chrysiptera cyanea is such a species, with individuals occurring in spatial clusters that varied widely in size and sex ratio. Typically, only one male defended a nest in multi-male groups. Nest-holding males were frequently visited by mate-searching females, with more visits in groups with more females, suggesting that courtship and mating mostly occur within groups and that male mating success depends on the number of females in the group. Male-male aggression was frequent in multi-male groups but absent in single-male groups. These findings demonstrate that groups are distinct social units. In consequence, the dynamics of mating and reproduction are mainly a result of group structure, largely unaffected short term by overall population demography which would be important in open social systems. Future studies of the C. cyanea model system should analyse longer-term dynamics, including how groups are formed, how they vary in relation to density and time of season and how social structure affects sexual selection.

Transition from a registered nurse to a clinical nurse educator (CNE) poses several challenges. Providing professional development opportunities to ease the transition from a registered nurse to a CNE is considered critical to a successful career and to effectively teach. A self-directed educational program and mentoring (SEM) program was designed and implemented to support nurse's transition from a novice to a confident CNE. The aim of this study was to explore novice CNE's experience of learning and being mentored. Qualitative methodology was undertaken to conduct focus groups. All CNEs who completed the SEM program were invited to participate in the study. Willing participants provided informed consent to complete an in-depth semi-structured focus group and to record the focus group interview. Focus groups were facilitated by an independent researcher. A second researcher attended the focus groups to collect detailed notes. Data were transcribed verbatim and participants were de-identified. Simple thematic analyses were undertaken. A total of 11 (58%) CNEs participated in the focus groups. Overall participants described their experience of the SEM program as positive. Three themes were identified: (1) perceived transformation of CNE practice, (2) beneficial relationships and (3) feeling connected. Mentoring relationships for some participants have continued beyond the self-directed learning, education and mentoring program. Barriers to the mentoring program included a theme of lack of time, role ambiguity and insufficient face to face education. Study findings highlight the benefits of providing professional development opportunities and mentoring programs for novice CNEs. Programs, such as the SEM enable transformation of a novice educator's practice, and the consolidation of new knowledge, skills and confidence to effectively educate less experienced nurses.

Linking structure, process, and outcome to improve group home services for foster youth in California.

The California Youth Connection obtained funding from two foundations to evaluate the performance of group homes serving foster youth in Alameda County, California, in order to inform state policy-making. The evaluation team initially included 14 foster youth that personally experienced group home living. Three inter-related aspects of service were studied: structure, process, and client outcomes, specifically residents' increase in developmental assets leading to the ability to transition successfully to independent living by the age of 18 years. Data were collected at 32 group homes from 127 residents and 72 staff members using three questionnaires. Both structural and process aspects of services influenced residents' satisfaction with services. However, only the process of care predicted changes in residents' developmental assets. State-level regulatory agencies learned from these results that auditing only structural aspects of services was not sufficient to promote effective services. Further, one structure item and two process items were identified as less consistently occurring in the group homes: timely distribution of clothing allowances, healthy communication between staff and youth, and staff support of regular exercise for the residents. Focusing on these aspects of service first should promote more change in outcomes and satisfaction for foster youth residing in group homes.

In recent years, researchers have demonstrated negative refraction theoretically and experimentally by pumping optical power into photonic crystal (PhC) or waveguide structures. The concept of negative refraction can be used to create a perfect lens that focuses an object smaller than the wavelength. By inserting two-dimensional PhCs into the peripheral of a semiconductor light emitting structure, this study presents an electroluminescent device with negative refraction in the visible wavelength range. This approach produces polarization dependent collimation behavior in far-field radiation patterns. The modal dispersion of negative refraction results in strong group velocity modulation, and self-focusing and -defocusing behaviors are apparent from light extraction. This study further verifies experimental results by using theoretic calculations based on equifrequency contours.

To describe nurses' support of breastfeeding on the night shift and to identify the interpersonal interactions and institutional structures that affect this support. Institutional ethnography. The mother/baby unit of a tertiary care hospital with 4200 births per year. Registered nurses (N = 16) who provided care on the night shift to mother/infant dyads in the immediate postpartum period. Data were collected using focus groups, individual and group interviews, and mother/baby unit observations. The focus groups were held before the night shift and had five participants. The nine individual and group interviews were conducted between 0100 and 0230 on the mother/baby unit. Three unit observations were conducted. Interviews were recorded, professionally transcribed, and analyzed using a content analysis method. Data analysis yielded three themes that described these nurses' support of breastfeeding on the night shift: competing priorities, incongruent expectations, and influential institutional structures. The need of visitors to see their new family members competed with the needs of mothers to rest and breastfeed their newborns. Helping breastfeeding dyads who experienced difficulties competed with providing care to other patients. Parents' expectations regarding newborn behavior were incongruent with the reality of newborn feeding and sleeping patterns. Institutional structures that affected the provision of breastfeeding support by nurses included hospital breastfeeding practices, staffing, and policies. Nurses' support of breastfeeding on the night shift encompasses a complex interplay of interpersonal interactions with new families and visitors regarding priorities and expectations and negotiating institutional structures such as feeding policies and staffing. © 2015 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Inertial Frames Without the Relativity Principle: Breaking Lorentz Symmetry

NASA Astrophysics Data System (ADS)

Baccetti, Valentina; Tate, Kyle; Visser, Matt

2015-01-01

We investigate inertial frames in the absence of Lorentz invariance, reconsidering the usual group structure implied by the relativity principle. We abandon the relativity principle, discarding the group structure for the transformations between inertial frames, while requiring these transformations to be at least linear (to preserve homogeneity). In theories with a preferred frame (aether), the set of transformations between inertial frames forms a groupoid/pseudogroup instead of a group, a characteristic essential to evading the von Ignatowsky theorems. In order to understand the dynamics, we also demonstrate that the transformation rules for energy and momentum are in general affine. We finally focus on one specific and compelling model implementing a minimalist violation of Lorentz invariance.

In 2010, a national integrated health care standard for (childhood) obesity was published and disseminated in the Netherlands. The aim of this study is to gain insight into the needs of health care providers and the barriers they face in terms of implementing this integrated health care standard. A mixed-methods approach was applied using focus groups, semi-structured, face-to-face interviews and an e-mail-based internet survey. The study's participants included: general practitioners (GPs) (focus groups); health care providers in different professions (face-to-face interviews) and health care providers, including GPs; youth health care workers; pediatricians; dieticians; psychologists and physiotherapists (survey). First, the transcripts from the focus groups were analyzed thematically. The themes identified in this process were then used to analyze the interviews. The results of the analysis of the qualitative data were used to construct the statements used in the e-mail-based internet survey. Responses to items were measured on a 5-point Likert scale and were categorized into three outcomes: 'agree' or 'important' (response categories 1 and 2), 'disagree' or 'not important'. Twenty-seven of the GPs that were invited (51 %) participated in four focus groups. Seven of the nine health care professionals that were invited (78 %) participated in the interviews and 222 questionnaires (17 %) were returned and included in the analysis. The following key barriers were identified with regard to the implementation of the integrated health care standard: reluctance to raise the subject; perceived lack of motivation and knowledge on the part of the parents; previous negative experiences with lifestyle programs; financial constraints and the lack of a structured multidisciplinary approach. The main needs identified were: increased knowledge and awareness on the part of both health care providers and parents/children; a social map of effective intervention; structural funding; task rearrangements; a central care coordinator and structural information feedback from the health care providers involved. The integrated health care standard stipulate that the care of overweight or obese children be provided using an integrated approach. The barriers and needs identified in this study can be used to define strategies to improve the implementation of the integrated health care standard pertaining to overweight and obese children in the Netherlands.

This is a qualitative study using a focus group approach, conducted to determine factors influencing adherence to osteoporosis medications among older adults. Thirty-two patients aged 65 to 85 years from the greater Boston area who were prescribed an osteoporosis medication, 11 general medicine physicians and 1 nurse practitioner were recruited from Boston based hospitals affiliated with a large healthcare system. Focus groups consisting of 6 to 8 subjects including males and females were held separately for providers and patients and conducted until thematic saturation was reached. Responses were obtained from patients and providers during the focus group interviews conducted by a trained focus group moderator. All interviews were audio taped and transcribed by a medical transcriptionist. According to patients, factors affecting adherence to osteoporosis drugs included lack of knowledge about osteoporosis, dissatisfaction with their doctor visits, side effects, and difficulty or failure to remember instructions for taking medications. Physicians reported lack of patient knowledge, structural barriers, medication side effects, and the inability to track patients’ adherence to their medications as barriers to adherence. This study identifies the extent of and reasons for non-adherence as perceived by patients and providers, and provides insights into strategies to modify treatment plans to address non-adherence. The results from this study were used to develop a RCT to conduct and evaluate patient and physician targeted interventions to improve adherence to osteoporosis medications and to examine cost effectiveness of alternative strategies.

Purpose To examine family (patient and parent/guardian) and clinician preferences for identification and management of obesity and obesity-related conditions during the well-child visit. Methods Four focus groups with teen patients (n=16), four focus groups with parents (n=15), and one focus group with providers (n=12) were conducted using a structured moderator guide tailored to each specific population. Eligible patients had a well-child visit during the past 12 months and a diagnosis of overweight, obesity, hyperlipidemia, or elevated blood pressure. Parents who attended their child’s well-child visit and had a child meeting these same criteria were eligible. Teen focus groups were divided by gender (male/female) and age (14-15y/16-17y). Focus group transcripts were coded for concepts and themes using qualitative data and thematic analysis. Analysis was performed across groups to determine common themes and domains of intersect. Results Teens and parents expect weight to be discussed at well-child visits, and prefer discussions to come from a trusted clinician who uses serious, consistent language. Teens did not recognize the health implications from excess weight, and both parents and teens express the need for more information on strategies to change behavior. Providers recognize several challenges and barriers to discussing weight management in the well-child visit. Conclusion A clinician-teen-family relationship built on trust, longevity, teamwork, support, and encouragement can create a positive atmosphere and may improve understanding for weight-related messages for teens and families during a well-child visit.

Crystalline lenses with multiple focal lengths in monochromatic light (multifocal lenses) are present in many vertebrate groups. These lenses compensate for chromatic aberration and create well-focused color images. Stabilization of the lens within the eye and the ability to adjust focus are further requirements for vision in high detail. We investigated the occurrence of multifocal lenses by photorefractometry and lens suspension structures by light and electron microscopy in sturgeons (Acipenseriformes, Chondrostei) as well as sharks and rays (Elasmobranchii, Chondrichthyes). Multifocal lenses were found in two more major vertebrate groups, the Chondrostei represented by Acipenseriformes and Chondrichthyes represented by Elasmobranchii. The lens suspension structures of sturgeons, sharks, and rays are more complex than described previously. The lens is suspended by many delicate suspensory fibers in association with a ventral papilla in all groups studied. The arrangements of the suspensory fibers are most similar between sturgeons and sharks. In rays, the lens is suspended by a smaller ventral papilla and the suspensory fibers are arranged more concentrically to the lens. Copyright © 2012 Wiley Periodicals, Inc.

Objective The aim of the present study was to describe an environmental framework for pharmacists in primary care in Australia and determine the major factors within that environment that have the greatest bearing on their capacity to implement patient-focused models of professional practice. Methods A draft framework for pharmacists' practice was developed by allocating structures, systems and related factors known to the researchers or identified from the literature as existing within pharmacists' internal, operational and external environments to one of five domains: Social, Technological, Economic, Environmental or Political [STEEP]. Focus groups of pharmacists used an adapted nominal group technique to assess the draft and add factors where necessary. Where applicable, factors were consolidated into groups to establish a revised framework. The three major factors or groups in each domain were identified. The results were compared with the enabling factors described in the profession's vision statement. Results Seventy-eight individual factors were ultimately identified, with 86% able to be grouped. The three dominant groups in each of the five domains that had a bearing on the implementation of professional models of practice were as follows: (1) Social: the education of pharmacists, their beliefs and the capacity of the pharmacist workforce; (2) Technological: current and future practice models, technology and workplace structures; (3) Economic: funding of services, the viability of practice and operation of the Pharmaceutical Benefits Scheme; (4) Environmental: attitudes and expectations of stakeholders, including consumers, health system reform and external competition; and (5) Political: regulation of practice, representation of the profession and policies affecting practice. Conclusions The three dominant groups of factors in each of the five STEEP environmental domains, which have a bearing on pharmacists' capacity to implement patient-focused models of practice, correlate well with the enabling factors identified in the profession's vision statement, with the addition of three factors in the Environmental domain of stakeholder attitudes, health system reform and external competition. What is known about the topic? The extensive range of patient-focused professional programs developed for application by pharmacists in primary care in Australia has yet to be widely implemented. What does this paper add? Factors both within and beyond the pharmacists' immediate practice environment that have a bearing on the uptake of professional programs have been identified and prioritised using a structured thematic approach. What are the implications for practitioners? The results demonstrate the need for a multifactorial approach to the implementation of professional models of practice in this setting.

Older adult active retirement groups encompass health promotion, social and community psychological potential. However, little is known about the internal dynamics of these groups or their contribution to individual well-being and the community. This paper examines the Third Age Foundation as an example of one such group operating in a rural area in Ireland and explores the various relationships at work internally and externally. Methodology included: structured and semi-structured interviews, focus groups and a postal survey. A substantial contribution to members' well-being and community competence and cohesion was found. Findings are discussed in reference to the importance of individual and community empowerment, sustainability, social entrepreneurship/leadership and the potential of such models to support community-based living in older age.

In the present study, protecting groups of moderate stability, such as acetals and ketals, were investigated as pendant blocking groups in polyvinyl phenols. Polymers were obtained by reacting enol ethers with the phenolic side groups to form acetal or ketal blocked phenols. Decomposition temperatures, glass transition temperatures, and molecular weights of the resulting polymers were monitored and correlated with the protecting group structure. Stability of the protecting groups can be explained by protonation occurring at either of the two oxygen sites, making two cleavage routes possible. Secondary reactions of the released protecting groups in the resist film were investigated and discussed. The structure of the protecting group was designed in order to meet basic resist properties such as resolution/linearity, DOF, post exposure delay latitude and thermal stability. A Canon FPA 4500 (NA equals 0.37) and a GCA XLS exposure tool (NA equals 0.53) were used for the optimization process. A preoptimized resist formulation based on the above criteria exhibits 0.23 micrometers line/space resolution, 0.8 micrometers focus latitude at 0.25 micrometers resolution and approximately two hours post exposure delay latitude.

Using interviews and focus groups with resource managers to explore risk perceptions and responses to climate scenarios

Resource managers in the western U.S. are increasingly tasked to incorporate climate change into management decisions and long-term planning, but this task is complicated by multiple challenges, among them the need to bridge between the differing perspectives and prerogatives of scientists and resource managers. As part of a larger, iterative, interdisciplinary, multi-landscape research project that built on a prior climate vulnerability research, we conducted more than 50 semi-structured interviews and four focus groups with resource managers in the Gunnison Basin in western Colorado. The interviews addressed the managers' risk perceptions and knowledge about the resources and landscapes, while the focus groups asked resource managers to reflect on their own resource decision-making in light of three narrative future climate scenarios created by scientists on the research team. While time-intensive, the interviews and focus groups produced important insights into the managers' understanding of both the resources in question and the future climate scenarios. We found that the managers' mental models of their systems, and their conceptions of landscape changes and future threats, were diverse and sometimes in conflict with those held by the research team. The managers' responses to the climate scenarios reflected divergent and nuanced perceptions of risk, adaptation and uncertainty, heavily shaped by personal experience—which could be a constraint under rapidly changing future conditions. Our deployment of social science methodologies facilitated the co-production of climate adaptation strategies and a bridge between and among scientists and managers. The participants found the focus groups helpful since they (1) provided space to focus on decision-making under climate change, rather than fixate on details of the science, and (2) facilitated interaction with colleagues from other agencies. Climate scientists used participant feedback to inform future scenario development. The use of small focus groups to engage with climate scenarios could add value to other ongoing efforts to promote landscape-scale adaptation.

2016-09-01

The current method for calculating extreme wave loads on offshore wind turbine structures is based on engineering models for non-breaking regular waves. The present article has the aim of validating previously developed models at DTU, namely the OceanWave3D potential flow wave model and a coupled OceanWave3D-OpenFOAM solver, against measurements of focused wave group impacts on a monopile. The focused 2D and 3D wave groups are reproduced and the free surface elevation and the in-line forces are compared to the experimental results. In addition, the pressure distribution on the monopile is examined at the time of maximum force and discussed in terms of shape and magnitude. Relative pressure time series are also compared between the simulations and experiments and detailed pressure fields for a 2D and 3D impact are discussed in terms of impact type. In general a good match for free surface elevation, in-line force and wave-induced pressures is found.

Abstract Background While autism and attention-deficit/hyperactivity disorder (ADHD) are considered distinct conditions from a diagnostic perspective, clinically they share some phenotypic features and have high comorbidity. Regardless, most studies have focused on only one condition, with considerable heterogeneity in their results. Taking a dual-condition approach might help elucidate shared and distinct neural characteristics. Method Graph theory was used to analyse topological properties of structural covariance networks across both conditions and relative to a neurotypical (NT; n = 87) group using data from the ABIDE (autism; n = 62) and ADHD-200 datasets (ADHD; n = 69). Regional cortical thickness was used to construct the structural covariance networks. This was analysed in a theoretical framework examining potential differences in long and short-range connectivity, with a specific focus on relation between central graph measures and cortical thickness. Results We found convergence between autism and ADHD, where both conditions show an overall decrease in CT covariance with increased Euclidean distance between centroids compared with a NT population. The 2 conditions also show divergence. Namely, there is less modular overlap between the 2 conditions than there is between each condition and the NT group. The ADHD group also showed reduced cortical thickness and lower degree in hub regions than the autism group. Lastly, the ADHD group also showed reduced wiring costs compared with the autism groups. Conclusions Our results indicate a need for taking an integrated approach when considering highly comorbid conditions such as autism and ADHD. Furthermore, autism and ADHD both showed alterations in the relation between inter-regional covariance and centroid distance, where both groups show a steeper decline in covariance as a function of distance. The 2 groups also diverge on modular organization, cortical thickness of hub regions and wiring cost of the covariance network. Thus, on some network features the groups are distinct, yet on others there is convergence. PMID:28633299

The purpose of this preliminary study was to describe a novel approach to examine the thinking of parents and young teens about conflict and conflict resolution in their relationship. The novel approach was that teens and parents were asked to solve, in focus groups, a hypothetical conflict situation without, and then with, a structured conflict resolution guide. Two focus groups were conducted. The resulting data were analyzed with use of content analysis from a sample of 8 parent-young teen dyads. The young teens and their parents participated separately from one another in the focus groups. Data demonstrated that the young teens (a) thought parents or siblings initiated most disagreements and that such disagreements were routine, and (b) handled conflict with their parents by trying to prevent it. If a conflict ensued, they used emotion, aggression, cooling off, accepting some of the blame, or submission to resolve it. Parents viewed the disagreements as (a) representing their struggles with their role as a parent or (b) opportunities to instill a sense of intrinsic responsibility in their child. Parents used the strategies of setting clear expectations, parental authority, negotiation, cooling down, and feedback to solve disagreements with their teenage children. We concluded that these parents and young teens do not use a systematic method of solving disagreements but that with structured guidance, the parents and teens were able to resolve conflicts.

CePt2In7 belongs to the CemMnIn3 m + 2 n heavy fermion family, but compared to the Ce MIn5 members of this group, exhibits a more two dimensional electronic structure. At zero pressure the ground state is antiferromagnetically ordered. Under pressure the antiferromagnetic order is suppressed and a superconducting phase is induced, with a maximum Tc above a quantum critical point around 31 kbar. To investigate the changes in the Fermi Surface and effective electron masses around the quantum critical point, Shubnikov-de Haas measurements were conducted under high pressures in an anvil cell. The samples were micro-structured and contacted using a Focused Ion Beam (FIB). The Focused Ion Beam enables sample contacting and structuring down to a sub-micrometer scale, making the measurement of several samples with complex shapes and multiple contacts on a single anvil feasible.

Dynamics of focused femtosecond laser pulse during photodisruption of crystalline lens

Gupta, Pradeep Kumar; Singh, Ram Kishor; Sharma, R. P.

2018-04-01

Propagation of laser pulses of femtosecond time duration (focused through a focusing lens inside the crystalline lens) has been investigated in this paper. Transverse beam diffraction, group velocity dispersion, graded refractive index structure of the crystalline lens, self-focusing, and photodisruption in which plasma is formed due to the high intensity of laser pulses through multiphoton ionization have been taken into account. The model equations are the modified nonlinear Schrödinger equation along with a rate equation that takes care of plasma generation. A close analysis of model equations suggests that the femtosecond laser pulse duration is critical to the breakdown in the lens. Our numerical simulations reveal that the combined effect of self-focusing and multiphoton ionization provides the breakdown threshold. During the focusing of femtosecond laser pulses, additional spatial pulse splitting arises along with temporal splitting. This splitting of laser pulses arises on account of self-focusing, laser induced breakdown, and group velocity distribution, which modifies the shape of laser pulses. The importance of the present study in cavitation bubble generation to improve the elasticity of the eye lens has also been discussed in this paper.

Travelling Wave Solutions in Multigroup Age-Structured Epidemic Models

Ducrot, Arnaut; Magal, Pierre; Ruan, Shigui

2010-01-01

Age-structured epidemic models have been used to describe either the age of individuals or the age of infection of certain diseases and to determine how these characteristics affect the outcomes and consequences of epidemiological processes. Most results on age-structured epidemic models focus on the existence, uniqueness, and convergence to disease equilibria of solutions. In this paper we investigate the existence of travelling wave solutions in a deterministic age-structured model describing the circulation of a disease within a population of multigroups. Individuals of each group are able to move with a random walk which is modelled by the classical Fickian diffusion and are classified into two subclasses, susceptible and infective. A susceptible individual in a given group can be crisscross infected by direct contact with infective individuals of possibly any group. This process of transmission can depend upon the age of the disease of infected individuals. The goal of this paper is to provide sufficient conditions that ensure the existence of travelling wave solutions for the age-structured epidemic model. The case of two population groups is numerically investigated which applies to the crisscross transmission of feline immunodeficiency virus (FIV) and some sexual transmission diseases.

Argumentation as a Lens to Examine Student Discourse in Peer-Led Guided Inquiry for College General Chemistry

NASA Astrophysics Data System (ADS)

Kulatunga, Ushiri Kumarihamy

This dissertation work entails three related studies on the investigation of Peer-Led Guided Inquiry student discourse in a General Chemistry I course through argumentation. The first study, Argumentation and participation patterns in general chemistry peer-led sessions, is focused on examining arguments and participation patterns in small student groups without peer leader intervention. The findings of this study revealed that students were mostly engaged in co-constructed arguments, that a discrepancy in the participation of the group members existed, and students were able to correct most of the incorrect claims on their own via argumentation. The second study, Exploration of peer leader verbal behaviors as they intervene with small groups in college general chemistry, examines the interactive discourse of the peer leaders and the students during peer leader intervention. The relationship between the verbal behaviors of the peer leaders and the student argumentation is explored in this study. The findings of this study demonstrated that peer leaders used an array of verbal behaviors to guide students to construct chemistry concepts, and that a relationship existed between student argument components and peer leader verbal behaviors. The third study, Use of Tolumin's Argumentation Scheme for student discourse to gain insight about guided inquiry activities in college chemistry , is focused on investigating the relationship between student arguments without peer leader intervention and the structure of published guided inquiry ChemActivities. The relationship between argumentation and the structure of the activities is explored with respect to prompts, questions, and the segmented Learning Cycle structure of the ChemActivities. Findings of this study revealed that prompts were effective in eliciting arguments, that convergent questions produced more arguments than directed questions, and that the structure of the Learning Cycle successfully scaffolded arguments. A semester of video data from two different small student groups facilitated by two different peer leaders was used for these three related studies. An analytic framework based on Toulmin's argumentation scheme was used for the argumentation analysis of the studies. This dissertation work focused on the three central elements of the peer-led classroom, students, peer leader, and the ChemActivities, illuminates effective discourse important for group learning. Overall, this dissertation work contributes to science education by providing both an analytic framework useful for investigating group processes and crucial strategies for conducting effective cooperative learning and promoting student argumentation. The findings of this dissertation work have valuable implications in the professional development of teachers specifically for group interventions in the implementation of cooperative learning reforms.

Discriminative latent models for recognizing contextual group activities.

2012-08-01

In this paper, we go beyond recognizing the actions of individuals and focus on group activities. This is motivated from the observation that human actions are rarely performed in isolation; the contextual information of what other people in the scene are doing provides a useful cue for understanding high-level activities. We propose a novel framework for recognizing group activities which jointly captures the group activity, the individual person actions, and the interactions among them. Two types of contextual information, group-person interaction and person-person interaction, are explored in a latent variable framework. In particular, we propose three different approaches to model the person-person interaction. One approach is to explore the structures of person-person interaction. Differently from most of the previous latent structured models, which assume a predefined structure for the hidden layer, e.g., a tree structure, we treat the structure of the hidden layer as a latent variable and implicitly infer it during learning and inference. The second approach explores person-person interaction in the feature level. We introduce a new feature representation called the action context (AC) descriptor. The AC descriptor encodes information about not only the action of an individual person in the video, but also the behavior of other people nearby. The third approach combines the above two. Our experimental results demonstrate the benefit of using contextual information for disambiguating group activities.

In this paper, we go beyond recognizing the actions of individuals and focus on group activities. This is motivated from the observation that human actions are rarely performed in isolation; the contextual information of what other people in the scene are doing provides a useful cue for understanding high-level activities. We propose a novel framework for recognizing group activities which jointly captures the group activity, the individual person actions, and the interactions among them. Two types of contextual information, group-person interaction and person-person interaction, are explored in a latent variable framework. In particular, we propose three different approaches to model the person-person interaction. One approach is to explore the structures of person-person interaction. Differently from most of the previous latent structured models, which assume a predefined structure for the hidden layer, e.g., a tree structure, we treat the structure of the hidden layer as a latent variable and implicitly infer it during learning and inference. The second approach explores person-person interaction in the feature level. We introduce a new feature representation called the action context (AC) descriptor. The AC descriptor encodes information about not only the action of an individual person in the video, but also the behavior of other people nearby. The third approach combines the above two. Our experimental results demonstrate the benefit of using contextual information for disambiguating group activities. PMID:22144516

This paper describes the developments, role and contributions of the NMR spectroscopy groups in the Structural Proteomics In Europe (SPINE) consortium. Focusing on the development of high-throughput (HTP) pipelines for NMR structure determinations of proteins, all aspects from sample preparation, data acquisition, data processing, data analysis to structure determination have been improved with respect to sensitivity, automation, speed, robustness and validation. Specific highlights are protonless (13)C-direct detection methods and inferential structure determinations (ISD). In addition to technological improvements, these methods have been applied to deliver over 60 NMR structures of proteins, among which are five that failed to crystallize. The inclusion of NMR spectroscopy in structural proteomics pipelines improves the success rate for protein structure determinations.

This study explores the way groups cope with collective responsibility for ecological problems. The social representations approach was adopted, and the collective symbolic coping model was used as a frame of analysis, integrating collective emotions to enhance the understanding of coping processes. The original feature of this study is that the analysis is at group level. Seven focus groups were conducted with French students. An original use of focus groups was proposed: Discussions were structured to induce feelings of collective responsibility and enable observation of how groups cope with such feelings at various levels (social knowledge; social identities; group dynamics). Two analyses were conducted: Qualitative analysis of participants' use of various kinds of knowledge, social categories and the group dynamics, and lexicometric analysis to reveal how emotions varied during the different discussion phases. Results showed that groups' emotional states moved from negative to positive: They used specific social categories and resorted to shared stereotypes to cope with collective responsibility and maintain the integrity of their worldview. Only then did debate become possible again; it was anchored in the nature-culture dichotomy such that groups switched from group-based to system-based emotions. © 2015 The British Psychological Society.

The teacher's role in promoting collaborative dialogue in the classroom.

Research on student-led small-group learning in schools going back nearly four decades has documented many types of student participation that promote learning. Less is known about how the teacher can foster effective groupwork behaviours. This paper reviews research that explores the role of the teacher in promoting learning in small groups. The focus is on how students can learn from their peers during small-group work, how teachers can prepare students for collaborative group work, and the role of teacher discourse and classroom norms in small-group dialogue. Studies selected for review focused on student-led small-group contexts for learning in which students were expected to collaborate, reported data from systematic observations of group work, and linked observational data to teacher practices and student learning outcomes. This review uncovered multiple dimensions of the teacher's role in fostering beneficial group dialogue, including preparing students for collaborative work, forming groups, structuring the group-work task, and influencing student interaction through teachers' discourse with small groups and with the class. Common threads through the research are the importance of students explaining their thinking, and teacher strategies and practices that may promote student elaboration of ideas.

To explore Cambodian community members' understanding of and attitudes towards healthcare research. This qualitative study generated data from semi-structured interviews and focus group discussions. This study was conducted at a non-governmental paediatric hospital and in nearby villages in Siem Reap province, Cambodia. A total of ten semi-structured interviews and four focus group discussions were conducted, involving 27 participants. Iterative data collection and analysis were performed concurrently. Data were analysed by thematic content analysis and the coding structure was developed using relevant literature. Participants did not have a clear understanding of what activities related to research compared with those for routine healthcare. Key attitudes towards research were responsibility and trust: personal (trust of the researcher directly) and institutional (trust of the institution as a whole). Villagers believe the village headman holds responsibility for community activities, while the village headman believes that this responsibility should be shared across all levels of the government system. It is essential for researchers to understand the structure and relationship within the community they wish to work with in order to develop trust among community participants. This aids effective communication and understanding among all parties, enabling high quality ethical research to be conducted.

To examine the beliefs and attitudes of FPs and health care professionals (HCPs) regarding FPs' roles and responsibilities on interdisciplinary geriatric health care teams. Qualitative study using focus groups. Calgary Health Region. Seventeen FPs and 22 HCPs working on geriatric health care teams. Four 90-minute focus groups were conducted with FPs, followed by 2 additional 90-minute focus groups with HCPs. The FP focus groups discussed 4 vignettes of typical teamwork scenarios. Discussions were transcribed and the 4 researchers analyzed and coded themes and subthemes and developed the HCP focus group questions. These questions asked about HCPs' expectations of FPs on teams, experiences with FPs on teams, and perspectives on optimal roles on teams. Several meetings were held to determine themes and subthemes. Family physicians identified patient centredness, role delineation for team members, team dynamics, and team structure as critical to team success. Both FPs and HCPs had a continuum of beliefs about the role FPs should play on teams, including whether FPs should be autonomous or collaborative decision makers, the extent to which FPs should work within or outside teams, whether FPs should be leaders or simply members of teams, and the level of responsibility implied or explicit in their roles. Comments from FPs and HCPs identified intraprofessional and interprofessional tensions that could affect team practice and impede the development of high-functioning teams. It will be important, as primary care reform continues, to help FPs and HCPs learn how to work together effectively on teams so that patients receive the best possible care.

One form of self-medication is sharing of medications, defined as borrowing or lending medications in situations where the receiver of these drugs is not the individual to whom the medications were allocated. To explore experiences and opinions of patients about sharing prescription analgesics, reasons for sharing prescription analgesics, the way in which patients choose to share those medications, their awareness of risk regarding sharing prescription analgesics, and how they estimated the potential risk. This qualitative study was conducted by focus group discussions with 40 participants led by a moderator trained in focus group methodology using a semi-structured moderator guide. Adults aged ≥18 years who had received a prescription for an analgesic at least once in a lifetime were included. Six separate focus groups were conducted to discuss participants' perception of risks associated with sharing of prescription analgesics among patients. Additionally, participants filled out two questionnaires on demographic data, their own behavior regarding sharing analgesics, and their attitudes about risks associated with sharing prescription analgesics. In a questionnaire, 55% of the participants indicated that they personally shared prescription analgesics, while subsequently in the focus group discussions, 76% confessed to such behavior. Participants recognized certain risks related to sharing of prescription analgesics, mentioned a number of reasons for engaging in such behavior, and indicated certain positive aspects of such behavior. Forty-five percent of the participants indicated that sharing prescription analgesics is riskier than sharing nonprescription analgesics. There is a prevalent attitude among participants that sharing prescription analgesics is a positive behavior, where potential benefits outweigh risks.

Lesbian, bisexual, queer and transgender (LBQT) women living with HIV have been described as invisible and understudied. Yet, social and structural contexts of violence and discrimination exacerbate the risk of HIV infection among LBQT women. The study objective was to explore challenges in daily life and experiences of accessing HIV services among HIV-positive LBQT women in Toronto, Canada. We used a community-based qualitative approach guided by an intersectional theoretical framework. We conducted two focus groups; one focus group was conducted with HIV-positive lesbian, bisexual and queer women (n = 7) and the second with HIV-positive transgender women (n = 16). Participants were recruited using purposive sampling. Focus groups were digitally recorded and transcribed verbatim. Thematic analysis was used for analyzing data to enhance understanding of factors that influence the wellbeing of HIV-positive LBQT women. Participant narratives revealed a trajectory of marginalization. Structural factors such as social exclusion and violence elevated the risk for HIV infection; this risk was exacerbated by inadequate HIV prevention information. Participants described multiple barriers to HIV care and support, including pervasive HIV-related stigma, heteronormative assumptions in HIV-positive women's services and discriminatory and incompetent treatment by health professionals. Underrepresentation of LBQT women in HIV research further contributed to marginalization and exclusion. Participants expressed a willingness to participate in HIV research that would be translated into action. Structural factors elevate HIV risk among LBQT women, limit access to HIV prevention and present barriers to HIV care and support. This study's conceptualization of a trajectory of marginalization enriches the discussion of structural factors implicated in the wellbeing of LBQT women and highlights the necessity of addressing LBQT women's needs in HIV prevention, care and research. Interventions that address intersecting forms of marginalization (e.g. sexual stigma, transphobia, HIV-related stigma) in community and social norms, HIV programming and research are required to promote health equity among LBQT women.

Background Information about genetics and the promise of genomic medicine is commonplace in the mass media. How the mass media themselves contribute – or not – to the persistence of this issue and its perception by the public is the topic of this presentation. The purpose of this study is to investigate the structural and individual perspectives on the issue of direct-to-consumer (DTC) genetics, and assess the degree of correspondence across these perspectives. Methods I conducted a media analysis to determine how the issue of DTC genetics has been framed in mass media stories and the salient topics related to the issue. I conducted focus groups to determine individual knowledge, attitudes and beliefs about the issue of DTC genetics. Results A final sample of 398 mass media stories of DTC genetics from Lexis-Nexis Academic archives between September 1, 2007 and September 30, 2009 were coded for salience and frames. Fourteen focus groups were conducted between October, 2009 and March, 2010 with Kaiser Permanente Colorado members and medical staff. Focus group transcripts were coded for salience and framing of the issue and compared with the media analysis results.Study results found that the issue of DTC genetics was not very important to focus group participants except as it related to the topic of breast cancer. Mass media message topics and frames showed differences over time. Focus group participants were generally negative towards the issue while the mass media was mostly positive towards DTC genetics. Focus group participants used some of the many frames to understand the issue that were utilized by the mass media to package the issue, but participants mainly framed the issue in terms of prevention and a pandora’s box, while the mass media presented the issue more in terms of progressive and discrimination frames. Conclusions The mass media appears to function as a field of power for the issue of DTC genetics with the consumers in the middle of the contests. A higher-level concept of an “informed consumer” emerged from the focus groups that appears to provide consumers a degree of power in this battlefield as well.

We aim to provide a clinically focused review of the neurobiological literature in body dysmorphic disorder (BDD), with a focus on structural and functional neuroimaging. There has been a recent influx of studies examining the underlying neurobiology of BDD using structural and functional neuroimaging methods. Despite obvious symptom similarities with obsessive-compulsive disorder (OCD), no study to date has directly compared the two groups using neuroimaging techniques. Studies have established that there are limbic and visual cortex abnormalities in BDD, in contrast to fronto-striatal differences in OCD. Such data suggests affect or visual training maybe useful in BDD. © The Royal Australian and New Zealand College of Psychiatrists 2015.

The Effects of Gender and Type of Inquiry Curriculum on Sixth Grade Students' Science Process Skills and Epistemological Beliefs in Science

NASA Astrophysics Data System (ADS)

Zaleta, Kristy L.

The purpose of this study was to investigate the impact of gender and type of inquiry curriculum (open or structured) on science process skills and epistemological beliefs in science of sixth grade students. The current study took place in an urban northeastern middle school. The researcher utilized a sample of convenience comprised of 303 sixth grade students taught by four science teachers on separate teams. The study employed mixed methods with a quasi-experimental design, pretest-posttest comparison group with 17 intact classrooms of students. Students' science process skills and epistemological beliefs in science (source, certainty, development, and justification) were measured before and after the intervention, which exposed different groups of students to different types of inquiry (structured or open). Differences between comparison and treatment groups and between male and female students were analyzed after the intervention, on science process skills, using a two-way analysis of covariance (ANCOVA), and, on epistemological beliefs in science, using a two-way multivariate analysis of covariance (MANCOVA). Responses from two focus groups of open inquiry students were cycle coded and examined for themes and patterns. Quantitative measurements indicated that girls scored significantly higher on science process skills than boys, regardless of type of inquiry instruction. Neither gender nor type of inquiry instruction predicted students' epistemological beliefs in science after accounting for students' pretest scores. The dimension Development accounted for 10.6% of the variance in students' science process skills. Qualitative results indicated that students with sophisticated epistemological beliefs expressed engagement with the open-inquiry curriculum. Students in both the sophisticated and naive beliefs groups identified challenges with the curriculum and improvement in learning as major themes. The types of challenges identified differed between the groups: sophisticated beliefs group students focused on their insecurity of not knowing how to complete the activities correctly, and naive beliefs group students focused on the amount of work and how long it took them to complete it. The description of the improvement in learning was at a basic level for the naive beliefs group and at a more complex level for the sophisticated beliefs group. Implications for researchers and educators are discussed.

Providing patients with validated information before total hip arthroplasty may help lessen discrepancies between patients' expectations and the surgical result. This study sought to validate an information booklet for candidates for hip arthroplasty by using a mixed qualitative and quantitative approach based on a panel of patients and a sample of healthcare professionals. We developed a booklet in accordance with the standard methods and then conducted focus groups to collect the opinions of a sample of multidisciplinary experts involved in the care of patients with hip osteoarthritis. The number of focus groups and experts was determined according to the data saturation principle. A panel of patients awaiting hip arthroplasty or those in the immediate post-operative period assessed the booklet with self-reporting questionnaires (knowledge, beliefs, and expectations) and semi-structured interviews. All experts and both patient groups validated the booklet in terms of content and presentation. Semi-structured interviews were uninformative, especially for post-operative patients. Reading the booklet significantly (P<0.001) improved the knowledge scores in both groups, with no intergroup differences, but did not affect beliefs in either patient group. Only pre-operative patients significantly changed their expectations. Our mixed qualitative and quantitative approach allowed us to validate a booklet for patients awaiting hip arthroplasty, taking into account the opinions of both patients and healthcare professionals.

A group of mink cell focus-forming (MCF) viruses was derived by inoculation of NFS/N mice with Moloney murine leukemia virus (Mo-MuLV 1387) and was compared to a similarly derived group of MCF viruses from mice inoculated with Friend MuLV (Fr-MuLV 57). Antigenic analyses using monoclonal antibodies specific for MCF virus and xenotropic MuLV envelope proteins and genomic structural analyses by RNase T1-resistant oligonucleotide finger-printing indicated that the Moloney and Friend MCF viruses arose by recombination of the respective ecotropic MuLVs with different endogenous retrovirus sequences of NFS mice.

The aim of this study was to explore how and why participants in structured exercise intervention programs continue or stop exercising after the program is finished. We conducted four focus group interviews with four groups of middle-aged and elderly men (total n = 28) who had participated in exercise interventions involving playing either a team sport (football) or a more individually focused activity (spinning and crossfit). Our results show that different social, organizational and material structures inherent in the different activities shape the subjects' enjoyment of exercise participation, as well as their intention and ability to continue being active. In conclusion, team sport activities seem to be intrinsically motivating to the participants through positive social interaction and play. They are therefore more likely to result in exercise continuation than activities that rely primarily on extrinsic motivation such as the expectation of improved health and well-being. © 2014 John Wiley & Sons A/S.

2017-01-01

Objective: To develop a descriptive model of structural characteristics of mHealth in the context of newborn nutrition, and to assess the effects of illustrative interventions through a mixed-methods study consisting of an impact evaluation and a qualitative assessment. Materials and Methods: We conducted a 23-week intervention with 100 mothers in rural Guatemala in 2013 and 2014. In group 1 (n = 24), participants received health-promoting text messages. In group 2 (n = 32), peer-to-peer groups were formed. In group 3 (n = 30), peer-to-peer groups were formed, a health professional participated in the discussions, and participants received health-promoting messages. In the control group (n = 14), participants were simply given a mobile phone. We measured changes in knowledge and self-reported behavior. Four focus groups in 2015 showed the perceptions of 44 additional women and the potential of the previously tested interventions in other marginalized areas. Results: Significant relationships were found between group membership and changes in knowledge (P < .001), and between changes in knowledge and self-reported behavior (P = .010). Within peer-to-peer groups, 3665 text messages were shared; discussions covered topics such as breastfeeding practices, health concerns, and emotional issues. Focus groups revealed a deficit of support for mothers, a precariousness of public services, different cultural barriers affecting access to care, and the potential for scaling up. Discussion: The complementarity of structural arrangements of mHealth interventions can play an important role in helping to encourage recommended breastfeeding attitudes along with providing rich information about challenges in rural areas. Conclusion: A mixed-methods study was appropriate to compare the effects and assess the potential of mHealth strategies in a complex rural setting. PMID:27474102

The diagnosis of epilepsy should be made as early as possible to give a child the best chance for treatment success and also to decrease complications such as learning difficulties and social and behavioral problems. In this study, we aimed to assess the ability of magnetic resonance spectroscopy (MRS) in detecting the lateralization side in patients with Temporal lobe epilepsy (TLE) in correlation with EEG and MRI findings. This was a case-control study including 40 patients diagnosed (clinically and by EEG) as having temporal lobe epilepsy aged 8 to 14 years (mean, 10.4 years) and 20 healthy children with comparable age and gender as the control group. All patients were subjected to clinical examination, interictal electroencephalography and magnetic resonance imaging (MRI). Proton magnetic resonance spectroscopic examination (MRS) was performed to the patients and the controls. According to the findings of electroencephalography, our patients were classified to three groups: Group 1 included 20 patients with unitemporal (lateralized) epileptic focus, group 2 included 12 patients with bitemporal (non-lateralized) epileptic focus and group 3 included 8 patients with normal electroencephalography. Magnetic resonance spectroscopy could lateralize the epileptic focus in 19 patients in group 1, nine patients in group2 and five patients in group 3 with overall lateralization of (82.5%), while electroencephalography was able to lateralize the focus in (50%) of patients and magnetic resonance imaging detected lateralization of mesial temporal sclerosis in (57.5%) of patients. Magnetic resonance spectroscopy is a promising tool in evaluating patients with epilepsy and offers increased sensitivity to detect temporal pathology that is not obvious on structural MRI imaging.

This article explores the experiences of a small group of Nairobi women caring for a family cancer patient at home. On the basis of literature on women as caregivers in Africa, and on other literature more broadly, it was anticipated that issues around generational roles, gender and women's cultural role would be relevant. Seven women participated in semi-structured in-depth interviews, while thirteen women participated in four mini focus groups. Data were analysed using interpretative phenomenological analysis. Findings underscore the socio-cultural complexities of caregiving as a basis for evidence-based culturally appropriate structures to support family caregivers.

ABSTRACT Purpose: To examine how a structured inter-professional education (IPE) clinical placement influences health care professional (HCP) students' perceptions of inter-professional collaboration (IPC) relative to that of students in a traditional clinical placement. Methods: This study used a mixed-methods design. The Interdisciplinary Education Perception Scale (IEPS) was administered to HCP students (n=36) in two Toronto hospitals before and after a structured 5-week IPE clinical placement to examine changes in their perceptions of IPC. Students in a traditional clinical placement (n=28) were used as a control group. Focus groups were then conducted with seven students who took part in the structured IPE clinical placement. A coding framework was devised a priori, and the qualitative results were used to explain the quantitative findings. Results: There were no statistically significant differences between groups after the structured IPE clinical placement, but the intervention group showed a greater positive trend in total IEPS scores from baseline to follow-up. Qualitative data suggest that students valued the knowledge and skills gained through the structured IPE clinical placement. Conclusions: Findings suggest that structured IPE clinical placements may provide students with valuable collaborative learning opportunities, enhanced respect for other professionals, and insight into the value of IPC in healthcare delivery. More research is needed to explore other factors that influence specific perceptions among physical therapy students. PMID:23450044

Notable aspects of the chemistry of complexes of polyether ligands including crown ethers, cryptands, glycols, glymes, and related polyether ligands with heavier group 13 and 14 elements are reviewed with a focus on results from 2005 to the present. The majority of reported polyether complexes contain lead(ii) and thallium(i) but recent breakthroughs in regard to the preparation of low oxidation state reagents of the lighter congeners have allowed for the generation of complexes containing indium(i), gallium(i), germanium(ii), and even silicon(ii). The important roles of ligand size, donor types, and counter anions in regard to the chemical properties of the polyether complexes is highlighted. A particular focus on the structural aspects of the numerous coordination complexes provides a rationale for some of the spectacular contributions that such compounds have made to Modern Main Group Chemistry.

It is widely acknowledged that the culture of medical group practices greatly influences the quality of care, but little is known about how cultures are translated into specific types of programs focused on quality. This study explores this issue by assessing the influence of the organizational culture on these types of programs in medical group practices in the upper Midwest. Data were obtained from two surveys of medical group practices. The first survey was designed to assess the culture of the practice using a nine-dimension instrument developed previously. The second survey was designed to obtain organizational structure data including the programs identified by the literature as important to the quality of care in medical practices. Completed surveys were obtained from eighty-eight medical groups. The relationship of the group practice culture to structural programs focused on quality of care was analyzed using logistic regression equations. Several interesting patterns emerged. As expected, practices with a strong information culture favor electronic data systems and formal programs that provide comparative or evidence-based data to enhance their clinical practices. However, those with a quality-centered culture appear to prefer patient satisfaction surveys to assess the quality of their care, while practices that are more business-oriented rely on bureaucratic strategies such as benchmarking and physician profiling. Cultures that emphasize the autonomy of physician practice were negatively (but not at a statistically significant level) associated with all the programs studied. Practices with a highly collegial culture appear to rely on informal peer review mechanisms to assure quality rather than any of the structural programs included in this analysis. This study suggests that the types of quality programs that group practices develop differ according to their cultures. Consequently, it is important for practice administrators and medical directors to develop quality assurance programs that fit their cultures if they are to gain buy-in by their clinicians. Future research should assess the effect of culture-structure fit on quality and safety outcomes.

The Aboriginal nations of Canada have higher incidences of chronic diseases, coinciding with profound changes in their environment, lifestyle and diet. Traditional foods can protect against the risks of chronic disease. However, their consumption is in decline, and little is known about the complex mechanisms underlying this trend. To identify the factors involved in traditional food consumption by Cree Aboriginal people living in 3 communities in northern Quebec, Canada. Design. A mixed methods explanatory design, including focus group interviews to interpret the results of logistic regression. This study includes a secondary data analysis of a cross-sectional survey of 3 Cree communities (n=374) and 4 focus group interviews (n=23). In the first, quantitative phase of the study, data were collected using a food-frequency questionnaire along with a structured questionnaire. Subsequently, the focus group interviews helped explain and build on the results of logistic regressions. People who consume traditional food 3 days or more weekly were more likely to be 40 years old and over, to walk 30 minutes or more per day, not to have completed their schooling, to live in Mistissini and to be a hunter (p<0.05 for all comparisons). The focus group participants provided explanations for the quantitative analysis results or completed them. For example, although no statistical association was found, focus group participants believed that employment acts as both a facilitator and a barrier to traditional food consumption, rendering the effect undetectable. In addition, focus group participants suggested that traditional food consumption is the result of multiple interconnected influences, including individual, family, community and environmental influences, rather than a single factor. This study sheds light on a number of factors that are unique to traditional foods, factors that have been understudied to date. Efforts to promote and maintain traditional food consumption could improve the overall health and wellbeing of Cree communities.

Embodied music cognition stresses the role of the human body as mediator for the encoding and decoding of musical expression. In this paper, we set up a low dimensional functional model that accounts for 70% of the variability in the expressive body movement responses to music. With the functional principal component analysis, we modeled individual body movements as a linear combination of a group average and a number of eigenfunctions. The group average and the eigenfunctions are common to all subjects and make up what we call the commonalities. An individual performance is then characterized by a set of scores (the individualities), one score per eigenfunction. The model is based on experimental data which finds high levels of coherence/consistency between participants when grouped according to musical education. This shows an ontogenetic effect. Participants without formal musical education focus on the torso for the expression of basic musical structure (tempo). Musically trained participants decode additional structural elements in the music and focus on body parts having more degrees of freedom (such as the hands). Our results confirm earlier studies that different body parts move differently along with the music.

2010-01-01

Schizophrenia has been the focus of intense neuroimaging research. Although its fundamental pathobiology remains elusive, neuroimaging studies provide evidence of abnormalities of cerebral structure and function in patients with schizophrenia. We used morphometry as a quantitative method for estimation of volume of brain structures. Seventy eight right-handed subjects aged 18-45 years were exposed to MRI-examination. Patients were divided into 3 groups: patients with schizophrenia, their relatives and healthy controls. The volumes of interested structures (caudate nucleus, putamen, ventricles, frontal and temporal lobe) were measured using T2-weighted MR-images. Correlations between structural differences and functional deficit were evaluated.

Background Continuity of care is fundamental to general practice and type 2 diabetes is a common chronic disease with major health and social impacts. Nevertheless continuity, as experienced by patients with type 2 diabetes, remains a neglected area. Aim To explore perceptions and experiences of continuity of care in general practice from the perspectives of patients with type 2 diabetes, focusing on the advantages and disadvantages of different types of continuity. Design of study Focus groups with patients. Setting Seven practices with different organisational structures in Leeds, UK. Method Seventy-nine patients with type 2 diabetes were recruited. Focus group interviews were conducted with 79 patients with type 2 diabetes from seven practices in Leeds, UK. Results Patients experienced three different types of continuity: relational (or longitudinal) continuity, cross-boundary (or team) continuity, and continuity of information. Patients' perceptions of continuity were influenced by several factors including a personal relationship between themselves and their healthcare professional, their own beliefs and behaviours, presence of diabetes, and the systems and structures of general practices. Patients identified the advantages and disadvantages of two types of continuity. Relational or longitudinal continuity was important in providing psychosocial care, but with a risk of misdiagnosis. The advantages of cross-boundary or team continuity were to provide physical care, whereas the main disadvantages were the absence of personal care and patient confusion. Conclusion Perceptions of continuity by patients with type 2 diabetes were influenced by several factors; they perceived several advantages and disadvantages associated with different types of continuity. Patients might expect certain healthcare benefits by following certain types of continuity. PMID:16834874

With the increasing focus on reducing hospital readmissions in the United States, numerous readmissions risk prediction models have been proposed, mostly developed through analyses of structured data fields in electronic medical records and administrative databases. Three areas that may have an impact on readmission but are poorly captured using structured data sources are patients' physical function, cognitive status, and psychosocial environment and support. The objective of the study was to build a discriminative model using information germane to these 3 areas to identify hospitalized patients' risk for 30-day all cause readmissions. We conducted clinician focus groups to identify language used in the clinical record regarding these 3 areas. We then created a dataset including 30,000 inpatients, 10,000 from each of 3 hospitals, and searched those records for the focus group-derived language using natural language processing. A 30-day readmission prediction model was developed on 75% of the dataset and validated on the other 25% and also on hospital specific subsets. Focus group language was aggregated into 35 variables. The final model had 16 variables, a validated C-statistic of 0.74, and was well calibrated. Subset validation of the model by hospital yielded C-statistics of 0.70-0.75. Deriving a 30-day readmission risk prediction model through identification of physical, cognitive, and psychosocial issues using natural language processing yielded a model that performs similarly to the better performing models previously published with the added advantage of being based on clinically relevant factors and also automated and scalable. Because of the clinical relevance of the variables in the model, future research may be able to test if targeting interventions to identified risks results in reductions in readmissions.

Purpose The purpose of this study was to investigate the beliefs and perceptions related to type 2 diabetes (diabetes) that influence diabetes self-management behaviors for Marshallese in the U.S. Utilizing the Health Belief Model as a theoretical framework, researchers seek to better understand the underlying beliefs that motivate or impede diabetes self-management behaviors. Methods The community-based participatory research (CBPR) collaborative engaged in 14 months of preliminary fieldwork and conducted two tiers of focus groups for this project as part of our long-term commitment to reducing health inequalities in the Marshallese community. The CBPR team conducted an initial round of two exploratory focus groups (n=15). Based on the knowledge gained, researchers held a second round of focus groups (n=13) focused on health beliefs regarding diabetes. All participants were Marshallese, aged 18 and older, and included men and women. Participants either had a diagnosis of diabetes or were a caretaker of someone with diabetes. Results The findings elucidate the structural and non-structural barriers to successful diabetes self-management for Marshallese in the US. Barriers include: eating differently than the rest of the family, social stigma of diabetes, transportation, cost, lack of access to healthcare, as well as cultural and language barriers. Conclusions While there are significant barriers to improving diabetes self-management, there are also areas of opportunity including family and peer reinforcement to encourage proper diabetes management behaviors and a growing community desire to lift the stigma of diabetes. The CBPR team offers recommendations to make diabetes management interventions more culturally appropriate and effective for the Marshallese population. PMID:25398722

Inadequate volume control may be a main contributor to poor survival and high mortality in hemodialysis patients. Bioimpedance measurement has the potential to improve fluid management, but several dialysis centers lack an agreed fluid management policy, and the method has not yet been implemented. Our aim was to identify renal care professionals' perceived barriers and facilitators for use of bioimpedance in clinical practice. Qualitative data were collected through four focus group interviews with 24 renal care professionals: dieticians, nephrologists and nurses, recruited voluntarily from a nation-wide selection of hemodialysis centers, having access to a bioimpedance-device. The participants were connected to each other and a moderator via equipment for telemedicine and the sessions were recorded. The interviews were semi-structured, focusing on the participants' perceptions of use of bioimpedance in clinical practice. Thematic content analysis was performed in consecutive steps, and data were extracted by employing an inductive, interactive, comparative process. Several barriers and facilitators to the use of bioimpedance in clinical practice were identified, and a multilevel approach to examining barriers and incentives for change was found to be applicable to the ideas and categories that arose from the data. The determinants were categorized on five levels, and the different themes of the levels illustrated with quotations from the focus groups participants. Determinants for use of bioimpedance were identified on five levels: 1) the innovation itself, 2) the individual professional, 3) the patient, 4) the social context and 5) the organizational context. Barriers were identified in the areas of credibility, awareness, knowledge, self-efficacy, care processes, organizational structures and regulations. Facilitators were identified in the areas of the innovation's attractiveness, advantages in practice, and collaboration. Motivation, team processes and organizational capacities appeared as both barriers and facilitators.

Purpose: Young women with breast cancer suffer distress both at the time of diagnosis and afterwards. This study aimed to elucidate which issues are most disturbing to this population and which might be amenable to intervention. Methods: English-speaking women treated or involved in research at the Dana-Farber Cancer Institute for stage I-III breast cancer while aged 18-42 years were invited to participate in one of four focus groups. A trained moderator led each 90-minute audio-recorded group using a semi-structured interview guide. All transcripts were coded using thematic content analysis with NVivo software. Results: Thirty-six women participated. Three major themes emerged from the analyses of these focus groups' data: (1) participants felt different from older breast cancer patients with regard to relationships, fertility, menopausal symptoms, treatment side effects, and work/finances; (2) participants faced unique challenges transitioning into the survivorship phase of care; and (3) participants desired assistance, including connections with other young patients, help navigating the healthcare system, educational materials, and lists of appropriate counselors. Conclusion: Young women with breast cancer have unmet needs for psychosocial support, education, and symptom management, and can identify potential support that may help meet these needs.

Career mentoring needs of youths in foster care: voices for change.

PubMed

Hudson, Angela L

2013-05-01

Adolescents with a history of foster care placement are more likely to become homeless, have mental illness, become parents too early in life, or become incarcerated within the juvenile justice/prison system. In addition, a low percentage of young adults, who formerly were in foster care, complete vocational training or higher education. This was a qualitative study, using focus group methodology. Four focus group sessions were conducted with youth living in foster care. The purpose was to obtain their perceptions about mentoring. Focus groups comprised six to eight youths per group and were guided by a semi-structured interview guide. A total of 27 youth in foster care participated in focus group interviews. Mean age was 16.4 (SD = 0.68) years. Youth participants were very knowledgeable about mentoring programs for at-risk youth, along with negative psychosocial outcomes experienced by former foster youth. However, they remarked that they are given few opportunities for career mentoring. The overall themes that emerged from narrative data were needing and finding authority figures, hooking up with a career mentor, and deserving the good life. Career mentoring is an affordable and feasible intervention for child welfare agencies. This could lead to more motivated and prepared youth living in foster care for vocational training or higher education. Learning opportunities from a career mentor may be a lifeline for preventing negative psychosocial outcomes for foster youth, reward achievement goals, and improve overall quality of life in emerging adulthood. © 2013 Wiley Periodicals, Inc.

To investigate whether concepts important to patients with ankylosing spondylitis (AS) are covered by disease-specific self-report health status instruments. A qualitative focus group study was conducted with AS patients on problems in daily functioning. Group sessions with 4 to 5 patients each were organized up to the point that no new information was brought forward. Group sessions were tape-recorded, transcribed, and divided into meaning units. Concepts contained in the meaning units were extracted. Self-report instruments on health status specific for AS were identified in a literature search. Using the International Classification of Functioning, Disability and Health (ICF) as a common reference, it was determined whether the concepts identified in the focus groups were covered by the instruments. Nineteen patients participated in 4 focus group interviews. In total, 332 unique meaning units were linked to 90 second-level ICF categories, of which 25 referred to body functions, 10 to body structures, 35 to activities and participation and 30 to environmental factors. In addition, several concepts relating to personal factors were identified. Only 47 categories were also covered by one of the self-report instruments in AS. Only a minority of concepts addressed by the AS-specific questionnaires were not revealed as relevant in the interviews. Relevant aspects of the influence of AS are not covered by the classic disease-specific instruments. In particular, the influence of AS on socializing and leisure and the relevance of environmental and personal factors are not adequately assessed by available instruments.

Machine learning in healthcare, and innovative healthcare technology in general, require complex interactions within multidisciplinary teams. Healthcare hackathons are being increasingly used as a model for cross-disciplinary collaboration and learning. The aim of this study is to explore high school student learning experiences during a healthcare hackathon. By optimizing their learning experiences, we hope to prepare a future workforce that can bridge technical and health fields and work seamlessly across disciplines. A qualitative exploratory study utilizing focus group interviews was conducted. Eight high school students from the hackathon were invited to participate in this study through convenience sampling Participating students (n = 8) were allocated into three focus groups. Semi structured interviews were completed, and transcripts evaluated using inductive thematic analysis. Through the structured analysis of focus group transcripts three major themes emerged from the data: (1) Collaboration, (2) Transferable knowledge and skills, and (3) Expectations about hackathons. These themes highlight strengths and potential barriers when bringing this multidisciplinary approach to high school students and the healthcare community. This study found that students were empowered by the interdisciplinary experience during a hackathon and felt that the knowledge and skills gained could be applied in real world settings. However, addressing student expectations of hackathons prior to the event is an area for improvement. These findings have implications for future hackathons and can spur further research into using the hackathon model as an educational experience for learners of all ages.

This study has focused on the pretreatment of cassava stillage residue (CSR) by mechanical activation (MA) using a self-designed stirring ball mill. The changes in surface morphology, functional groups and crystalline structure of pretreated CSR were examined by using scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) under reasonable conditions. The results showed that MA could significantly damage the crystal structure of CSR, resulting in the variation of surface morphology, the increase of amorphous region ratio and hydrogen bond energy, and the decrease in crystallinity and crystalline size. But no new functional groups generated during milling, and the crystal type of cellulose in CSR still belonged to cellulose I after MA. Copyright © 2011 Elsevier Ltd. All rights reserved.

Survey instruments for evaluating public health preparedness have focused on measuring the structure and capacity of local, state, and federal agencies, rather than linkages among structure, process, and outcomes. To focus evaluation on the latter, we evaluated the linkages among individuals, organizations, and systems using the construct of "connectivity" and developed a measurement instrument. Results from focus groups of emergency preparedness first responders generated 62 items used in the development sample of 187 respondents. Item reduction and factors analyses were conducted to confirm the scale's components. The 62 items were reduced to 28. Five scales explained 70% of the total variance (number of items, percent variance explained, Cronbach's alpha) including connectivity with the system (8, 45%, 0.94), coworkers (7, 7%, 0.91), organization (7, 12%, 0.93), and perceptions (6, 6%, 0.90). Discriminant validity was found to be consistent with the factor structure. We developed a Connectivity Measurement Tool for the public health workforce consisting of a 34-item questionnaire found to be a reliable measure of connectivity with preliminary evidence of construct validity.

2010-12-01

As part of the planning process for a larger survey study to examine factors affecting employers' intention to hire and hiring of people with disabilities, a series of three semi-structured focus groups were held with key hiring decision makers, such as Human Resources directors, Chief Operating Officers (COOs), or Chief Executive Officers (CEOs) of small, medium, and large Seattle area companies. The chief goals of the focus groups were to elicit and refine the participants' beliefs, normative influences, and perceived control relative to hiring workers with disabilities. Narrative data obtained from the focus group discussion were examined using the Theory of Planned Behavior (TPB) to identify themes expressed by the focus group participants within the context of company size. Themes did vary by company size, but a prevailing concern across all companies related to questions about the efficiency/effectiveness of contact with vocational rehabilitation agencies. For both small- and mid-sized companies, there was a belief that people with disabilities could not do the work or were somehow less qualified. For large companies, convincing departmental and team managers that outreaching workers with disabilities would be a worthwhile hiring practice remained a challenge. The themes derived from this study can be used to help occupational rehabilitation professionals develop educational and marketing interventions to improve employers' attitudes toward hiring and retaining individuals with disabilities.

Population-based association studies are powerful tools for the genetic mapping of complex diseases. However, this method is sensitive to potential confounding by population structure. While statistical methods that use genetic markers to detect and control for population structure have been the focus of current literature, the utility of self-defined race/ethnicity in controlling for population structure has been controversial. In this study of 1334 individuals, who self-identified as either African American, European American or Hispanic, we demonstrated that when the true underlying genetic structure and the self-defined racial/ethnic groups were roughly in agreement with each other, the self-defined race/ethnicity information was useful in the control of population structure.

The properties of infant skin regarding its structure and stratum corneum (SC) properties during development compared to adult skin have been reported only for a few races and body sites. The aim of this study was to understand the developmental changes of skin properties in Chinese infants, focusing on SC ceramides and protein secondary structure, which are important for skin barrier function. Three body sites with distinct characteristics (cheeks, inner upper arms, and buttocks) were assessed. Sixty pairs of Chinese infants and their mothers were measured for SC hydration, transepidermal water loss, ceramide levels, sebum with an ester bond, and protein secondary structure of superficial SC. Skin hydration decreased with age at all body sites. TEWL was similar between the 2–12- and 13–24-month-old groups but was higher than the adult group at the buttocks and inner upper arms and was equal to the adult group at the cheeks. These differences coincided with differences in protein secondary structure. Ceramide and sebum levels were lower in the infant groups. We conclude that both the SC functions and the components of infant skin are still developing and are not fully adapted as in adult skin at each body site examined. PMID:29098152

Utility of R0 as a predictor of disease invasion in structured populations

2007-01-01

Early theoretical work on disease invasion typically assumed large and well-mixed host populations. Many human and wildlife systems, however, have small groups with limited movement among groups. In these situations, the basic reproductive number, R0, is likely to be a poor predictor of a disease pandemic because it typically does not account for group structure and movement of individuals among groups. We extend recent work by combining the movement of hosts, transmission within groups, recovery from infection and the recruitment of new susceptibles into a stochastic model of disease in a host metapopulation. We focus on how recruitment of susceptibles affects disease invasion and how population structure can affect the frequency of superspreading events (SSEs). We show that the frequency of SSEs may decrease with the reduced movement and the group sizes due to the limited number of susceptible individuals available. Classification tree analysis of the model results illustrates the hierarchical nature of disease invasion in host metapopulations. First, the pathogen must effectively transmit within a group (R0 > 1), and then the pathogen must persist within a group long enough to allow for movement among the groups. Therefore, the factors affecting disease persistence - such as infectious period, group size and recruitment of new susceptibles - are as important as the local transmission rates in predicting the spread of pathogens across a metapopulation. ?? 2006 The Royal Society.

Depression in Aboriginal men in central Australia: adaptation of the Patient Health Questionnaire 9

PubMed Central

2013-01-01

Background While Indigenous Australians are believed to be at a high risk of psychological illness, few screening instruments have been designed to accurately measure this burden. Rather than simply transposing western labels of symptoms, this paper describes the process by which a screening tool for depression was specifically adapted for use across multiple Indigenous Australian communities. Method Potential depression screening instruments were identified and interrogated according to a set of pre-defined criteria. A structured process was then developed which relied on the expertise of five focus groups comprising of members from primary Indigenous language groups in central Australia. First, focus group participants were asked to review and select a screening measure for adaptation. Bi-lingual experts then translated and back translated the language within the selected measure. Focus group participants re-visited the difficult items, explored their meaning and identified potential ways to achieve equivalence of meaning. Results All five focus groups independently selected the Primary Health Questionnaire 9, several key conceptual differences were exposed, largely related to the construction of hopelessness. Together with translated versions of each instrument for each of the five languages, a single, simplified English version for use across heterogeneous settings was negotiated. Importantly, the ‘code’ and specific conceptually equivalent words that could be used for other Indigenous language groups were also developed. Conclusions The extensive process of adaptation used in this study has demonstrated that within the context of Indigenous Australian communities, across multiple language groups, where English is often a third or fourth language, conceptual and linguistic equivalence of psychological constructs can be negotiated. A validation study is now required to assess the adapted instrument’s potential for measuring the burden of disease across all Indigenous Australian populations. PMID:24139186

To assess healthcare personnel (HCP) perceptions regarding implementation of sensor-based electronic systems for automated hand hygiene adherence monitoring. Using a mixed-methods approach, structured focus groups were designed to elicit quantitative and qualitative responses on familiarity, comfort level, and perceived impact of sensor-based hand hygiene adherence monitoring. A university hospital, a Veterans Affairs hospital, and a community hospital in the Midwest. Focus groups were homogenous by HCP type, with separate groups held for leadership, midlevel management, and frontline personnel at each hospital. Overall, 89 HCP participated in 10 focus groups. Levels of familiarity and comfort with electronic oversight technology varied by HCP type; when compared with frontline HCP, those in leadership positions were significantly more familiar with ([Formula: see text]) and more comfortable with ([Formula: see text]) the technology. The most common concerns cited by participants across groups included lack of accuracy in the data produced, such as the inability of the technology to assess the situational context of hand hygiene opportunities, and the potential punitive use of data produced. Across groups, HCP had decreased tolerance for electronic collection of spatial-temporal data, describing such oversight as Big Brother. While substantial concerns were expressed by all types of HCP, participants' recommendations for effective implementation of electronic oversight technologies for hand hygiene monitoring included addressing accuracy issues before implementation and transparent communication with frontline HCP about the intended use of the data.

Cancer survivors (CSs) frequently return to work, but little is known about work functioning after return to work (RTW). We aimed to identify barriers and facilitators of work functioning among CSs. Three focus groups were conducted with CSs (n = 6, n = 8 and n = 8) and one focus group with occupational health professionals (n = 7). Concepts were identified by thematic analysis, using the Cancer and Work model as theoretical framework to structure the results. Long-lasting symptoms (e.g. fatigue), poor adaptation, high work ethics, negative attitude to work, ambiguous communication, lack of support and changes in the work environment were mentioned as barriers of work functioning. In contrast, staying at work during treatment, open dialogue, high social support, appropriate work accommodations and high work autonomy facilitated work functioning. Not only cancer-related symptoms affect work functioning of CSs after RTW but also psychosocial and work-related factors. The barriers and facilitators of work functioning should be further investigated in studies with a longitudinal design to examine work functioning over time.

Hysterectomy is the most common non-obstetrical surgery for women in the United States. Few investigations comparing hysterectomy surgical approaches include patient-centered outcomes. The study was performed at Henry Ford Health System in Detroit, Michigan between February 2015 and May 2015. The data were collected through structured focus groups with 24 post-hysterectomy women in order to identify PCOs to employ in a subsequent cohort study of hysterectomy surgical approaches. One pilot focus group and five additional focus groups were held. Qualitative data analysis, using data from coded transcripts of focus groups, was used to identify themes.Eligible women, aged between 18 and 65 years and had an EMR documented Current Procedural Terminology (CPT™) code or an International Statistical Classification of Diseases and Related Health Problems - Ninth Edition (ICD-9) code of hysterectomy between December 2012 and December 2014 (N=1,381, N=307 after exclusions) were selected and recruited. A question guide was developed to investigate women's experiences and feelings about the experience prior and subsequent to their hysterectomy. Analysis utilized the Framework Method. Focus groups with women who previously had a hysterectomy revealed their pre- and post-hysterectomy perceptions. Responses grouped into topics of pre- and post-surgical experiences, and information all women should know. Responses grouped into themes of 1) decision making, 2) the procedure - surgical experience, 3) recovery, 4) advice to past self, and 5) recommendations to other women. These findings about perceptions, beliefs, and attitudes of women having undergone hysterectomy could support health care providers deliver patient-centered care. These results informed data collection for a prospective longitudinal cohort study that is now underway. The data suggest a need for increased education and empowerment in the decision making process, while expanding on information given for post-operative expectations and somatic changes that occur post-hysterectomy.

2012-03-01

There is little evidence of the integration of UK physiotherapy university education into clinical practice, and some students say that they are not adequately prepared for professional life. This was addressed by a college-based programme involving patients, carers and service users as facilitators of learning to enhance the partnership between health professionals and patients. This programme has been running for 2 years, and this paper is an evaluation of the students' perceptions of it, appraising the outcomes of their learning in order to discover the ways in which it can be enhanced, improved or changed. A grounded theory approach utilizing focus groups and semi-structured interviews was conducted. Three focus groups representing the higher educational levels 4-6 in pre-registration physiotherapy were carried out. Following the analysis of the focus groups, seven interviews reflecting the three educational levels were conducted in order to explore in greater depth the findings from the focus groups. The analysis of the focus groups and the subsequent interviews were carried out in accordance with a grounded theory framework. The students perceived the programme as a context in which to think how their learning needs could be met within a 'real' framework but on their own territory. Equally, it created feelings of anxiety at being given such an open forum that created a challenge to their communication skills. Many expressed a wish for a more explicit mentoring-learning environment. They also perceived a tension between the technical-rational demands of academia and social practice and a need to view this as a basis for critical appraisal and self-awareness. This programme appeared to be integral to the students' development as future physiotherapists. Copyright © 2011 John Wiley & Sons, Ltd.

Social justice as a framework for professional nursing.

PubMed

Boutain, Doris M

2005-09-01

A persistent connection exists between health disparity and societal inequality. Since more research is designed to document, rather than alter, those trends, nurses are called on to reinvest in a social justice agenda. An educational focus on social justice is necessary to prepare future nurses to address health concerns related to how societies are structured. This article reports on how social justice was used as a framework to teach concepts related to professional nursing. The course structure is described, a focus on how the course content was taught is outlined, and conclusions are drawn. Linking content on social justice to professional nursing is important because research indicates that, if societal relationships are more equal, population health indicators between diverse groups become more stable nationally and globally.

Exploring reforms while learning to teach science: Facilitating exploration of theory-practice relationships in a teacher education study group

NASA Astrophysics Data System (ADS)

Foster, Jacob G.

This dissertation inserts a new view into an old problem in teacher education. The study explores the theory-practice gap, the large distance between what preservice science teachers experience in schools, are able to enact, and are told they should hold themselves to in their practice. It does so by narrowing the focus of analysis to a secondary science study group and examining how the facilitator uses sociocultural constructivism to promote discussion. The analysis surfaces key communicative moves made by the facilitator and preservice teachers that yield fruitful discussion of theory-practice relationships. Additionally, the study's use of discourse analysis as a methodology and intertextuality as a conceptual framework opens new directions for applied sociolinguistic research and scholarship in science teacher education. Findings from the study focus on what was discussed and how explorations of theory-practice relationships were facilitated. Preservice teachers in the study group engaged in meaningful conversations about constructivist theory and its application to their students and teaching of science. They discussed many science education topics such as planning science lessons that actively engage students, assessment of content understanding, and management of content-based activities. Discussions of broader science education goals, including implementation of inquiry or development of collaborative communities, were not promoted. Examination of the facilitation illuminates a number of strategies found to be helpful in supporting these explorations. This study shows that facilitation can successfully support preservice teachers to construct understanding of social constructivist assumptions underlying the National Science Education Standards (NSES), as well as a few components of the Standards themselves. The focus on the underlying assumptions suggests that science teacher education should focus on these so that preservice teachers can build a strong foundation from which to later implement broader science education reform efforts. The study group serves as a bridging structure between university courses and classroom experiences to support preservice teacher navigation of theory-practice relationships in the context of their classroom teaching. The study group contributes to helping preservice teachers navigate the theory-practice gap by complementing other teacher education structures to achieve this long-standing goal.

Understanding what matters most to people with multiple myeloma: a qualitative study of views on quality of life

PubMed Central

2014-01-01

Background Multiple myeloma is an incurable haematological cancer that affects physical, psychological and social domains of quality of life (QOL). Treatment decisions are increasingly guided by QOL issues, creating a need to monitor QOL within clinical practice. The development of myeloma-specific QOL questionnaires has been limited by a paucity of research to fully characterise QOL in this group. Aims of the present study are to (1) explore the issues important to QOL from the perspective of people with multiple myeloma, and (2) explore the views of patients and clinical staff on existing QOL questionnaires and their use in clinical practice. Methods The ‘Issues Interviews’ were semi-structured qualitative interviews to explore the issues important to QOL in a purposive sample of myeloma patients (n = 20). The ‘Questionnaire Interviews’ were semi-structured qualitative interviews in a separate purposive sample of myeloma patients (n = 20) to explore views on existing QOL questionnaires and their clinical use. Two patient focus groups (n = 7, n = 4) and a focus group of clinical staff (n = 6) complemented the semi-structured interviews. Thematic content analysis resulted in the development of a theoretical model of QOL in myeloma. Results Main themes important to QOL were Biological Status, Treatment Factors, Symptoms Status, Activity & Participation, Emotional Status, Support Factors, Expectations, Adaptation & Coping and Spirituality. Symptoms had an indirect effect on QOL, only affecting overall QOL if they impacted upon Activity & Participation, Emotional Status or Support Factors. This indirect relationship has implications for the design of QOL questionnaires, which often focus on symptom status. Health-service factors emerged as important but are often absent from QOL questionnaires. Sexual function was important to patients and difficult for clinicians to discuss, so inclusion in clinical QOL tools may flag hidden problems and facilitate better care. Patients and staff expressed preferences for questionnaires to be no more than 2 pages long and to include a mixture of structured and open questions to focus the goals of care on what is most important to patients. Conclusion Existing QOL questionnaires developed and validated for use in myeloma do not capture all that is important to patients and may not be well suited to clinical use. PMID:25005145

Do Low Income Youth of Color See "The Bigger Picture" When Discussing Type 2 Diabetes: A Qualitative Evaluation of a Public Health Literacy Campaign.

2018-04-24

As Type 2 diabetes spikes among minority and low-income youth, there is an urgent need to tackle the drivers of this preventable disease. The Bigger Picture (TBP) is a counter-marketing campaign using youth-created, spoken-word public service announcements (PSAs) to reframe the epidemic as a socio-environmental phenomenon requiring communal action, civic engagement and norm change. We examined whether and how TBP PSAs advance health literacy among low-income, minority youth. We showed nine PSAs, asking individuals open-ended questions via questionnaire, then facilitating a focus group to reflect upon the PSAs. Questionnaire responses revealed a balance between individual vs. public health literacy. Some focused on individual responsibility and behaviors, while others described socio-environmental forces underlying risk. The focus group generated a preponderance of public health literacy responses, emphasizing future action. Striking sociopolitical themes emerged, reflecting tensions minority and low-income youth experience, such as entrapment vs. liberation. Our findings speak to the structural barriers and complexities underlying diabetes risk, and the ability of spoken word medium to make these challenges visible and motivate action. Delivering TBP content to promote interactive reflection has potential to change behavioral norms and build capacity to confront the social, economic and structural factors that influence behaviors.

Embedding fundamental care in the pre-registration nursing curriculum: Results from a pilot study.

Feo, Rebecca; Donnelly, Frank; Frensham, Lauren; Conroy, Tiffany; Kitson, Alison

2018-05-01

International evidence suggests nursing is not providing fundamental care consistently or adequately, resulting in poor outcomes for patients and healthcare systems. One possible reason for this inadequate care delivery is nursing education, with fundamental care often implicit or invisible in nursing curricula. To understand how best to teach fundamental care to pre-registration (pre-licensure) students, we developed and piloted a six-week intervention that incorporated into the first-year curriculum a more explicit focus on fundamental care. A conceptual fundamental care framework was used to guide students' learning, and clinical skills sessions were structured to reinforce the framework's conceptual understanding and enable students to practice delivering fundamental care in an integrated manner. The intervention's impact was explored via a pre-post survey and focus groups. The survey demonstrated that the intervention did not affect students' ability to identify patients' fundamental care needs; however, focus groups showed the intervention assisted students in understanding the complexity of fundamental care and its importance to patients' experiences. The pilot provides preliminary evidence on the importance of embedding fundamental care into nursing curricula early and explicitly, and emphasising the integrated nature of such care, particularly through structured debriefs, consistent terminology, and opportunities for students to experience care as a patient.

The bacterial groups in the gut ecosystem play key role in the maintenance of host's metabolic and structural functionality. The gut microbiota enhances digestion processing, helps in digestion of complex substances, synthesizes beneficial bioactive compounds, enhances bioavailability of minerals, impedes growth of pathogenic microbes, and prevents various diseases. It is, therefore, desirable to have an adequate intake of prebiotic biomolecules, which promote favorable modulation of intestinal microflora. Prebiotics are non-digestible and chemically stable structures that significantly enhance growth and functionality of gut microflora. The non-digestible carbohydrate, mainly oligosaccharides, covers a major part of total available prebiotics as dietary additives. The review describes the types of prebiotic low molecular weight carbohydrates, i.e., oligosaccharides, their structure, biosynthesis, functionality, and applications, with a special focus given to fructooligosaccharides (FOSs). The review provides an update on enzymes executing hydrolytic and fructosyltransferase activities producing prebiotic FOS biomolecules, and future perspectives.

The effect of excluding juveniles on apparent adult olive baboons (Papio anubis) social networks

PubMed Central

Fedurek, Piotr; Lehmann, Julia

2017-01-01

In recent years there has been much interest in investigating the social structure of group living animals using social network analysis. Many studies so far have focused on the social networks of adults, often excluding younger, immature group members. This potentially may lead to a biased view of group social structure as multiple recent studies have shown that younger group members can significantly contribute to group structure. As proof of the concept, we address this issue by investigating social network structure with and without juveniles in wild olive baboons (Papio anubis) at Gashaka Gumti National Park, Nigeria. Two social networks including all independently moving individuals (i.e., excluding dependent juveniles) were created based on aggressive and grooming behaviour. We used knockout simulations based on the random removal of individuals from the network in order to investigate to what extent the exclusion of juveniles affects the resulting network structure and our interpretation of age-sex specific social roles. We found that juvenile social patterns differed from those of adults and that the exclusion of juveniles from the network significantly altered the resulting overall network structure. Moreover, the removal of juveniles from the network affected individuals in specific age-sex classes differently: for example, including juveniles in the grooming network increased network centrality of adult females while decreasing centrality of adult males. These results suggest that excluding juveniles from the analysis may not only result in a distorted picture of the overall social structure but also may mask some of the social roles of individuals belonging to different age-sex classes.

2011-01-01

This article examines the role of 3 types of perceived support for creativity in moderating the relation between creative self-efficacy and self-perceived creativity. The findings suggest significant interaction effects for perceived work-group support and supervisor support, but not for perceived organizational support. This study is among the first to (a) examine the importance of perceived support for creativity in unlocking creative potential and increasing creativity in organizations and (b) use interaction terms in structural equation modeling (SEM) to investigate moderator effects in an applied research setting. These results imply that organizational interventions focused on training supervisors and work-group members to support creativity in the workplace may be more effective than broader and less focused interventions at the organizational level.

2013-10-14

To evaluate the feasibility and effectiveness of using an online social networking platform for interprofessional education. Three groups of 6 students were formed with 1 student in each group from medicine, nursing, dentistry, pharmacy, veterinary medicine, and public health. Each group followed a different collaborative educational model with a unique pedagogical structure. Students in all groups interacted via an online social networking platform for a minimum of 15 weeks and met in person once at the end of the 15-week experience for a focus group session. The students were tasked with developing a collaborative recommendation for using social networking in interprofessional education programs. Most of the students who reported in a post-experience survey that their expectations were not met were in the minimally structured group. Almost all students in the facilitated and highly structured groups indicated that this experience positively impacted their knowledge of other health professions. Most students stated that interacting within a social networking space for 15 weeks with other members of the university's health professions programs was a positive and effective interprofessional education experience. Social networking is feasible and can be used effectively within an overall strategy for interprofessional education, but design and placement within a core content course is critical to success.

Taking 'women's work' 'like a man': husbands' experiences of care work.

PubMed

Calasanti, Toni; King, Neal

2007-08-01

We adopted a feminist, structural approach to husbands' experiences of caring for wives with Alzheimer's disease. This framework posited that men and women draw upon gender repertoires-situational ideals of behavior based upon their respective structural locations-that create gendered experiences of stress and coping strategies. We used a qualitative, constructivist approach to analyze in-depth interviews with 22 spousal caregivers and observations within support groups. Our analysis focused on the nine husbands, the strategies these men reported using to deal with problems that arose in their care work, and the extent to which these are congruent with the masculinities of White men in the United States. We found that these husbands' approaches to caregiving and their strategies for dealing with the work and feelings involved were rooted in their sense of selves as men. We outline their overall approaches to caregiving, identify six strategies husbands used to deal with problems stemming from care work-exerting force, focusing on tasks, blocking emotions, minimizing disruption, distracting attention, and self-medicating-and tie these to their structural positions as working-, middle-, and professional-class men. Theories of gender differences in the performance or quality of care work should tie these to structural arrangements. Unless the gendered bases upon which different styles or experiences are removed (i.e., structural inequality), designers of interventions cannot and should not expect to use the experience of one group to inform appropriate strategies for the other.

Monogamy, strongly bonded groups, and the evolution of human social structure.

PubMed

Chapais, Bernard

2013-01-01

Human social evolution has most often been treated in a piecemeal fashion, with studies focusing on the evolution of specific components of human society such as pair-bonding, cooperative hunting, male provisioning, grandmothering, cooperative breeding, food sharing, male competition, male violence, sexual coercion, territoriality, and between-group conflicts. Evolutionary models about any one of those components are usually concerned with two categories of questions, one relating to the origins of the component and the other to its impact on the evolution of human cognition and social life. Remarkably few studies have been concerned with the evolution of the entity that integrates all components, the human social system itself. That social system has as its core feature human social structure, which I define here as the common denominator of all human societies in terms of group composition, mating system, residence patterns, and kinship structures. The paucity of information on the evolution of human social structure poses substantial problems because that information is useful, if not essential, to assess both the origins and impact of any particular aspect of human society.

Little is known about the acceptance of non-pharmacological group strategies delivered to low income racially diverse patients with chronic pain and depression. This paper examines how the Integrative Medical Group Visit (IMGV) addresses many of the deficits identified with usual care. Six IMGVs cohorts were held at a safety net hospital and two federally funded community health centres. Data was gathered through focus groups. Transcripts were analysed using both a priori codes and inductive coding. The intervention included ten sessions of Integrative Medical Group Visits with a primary care provider and a meditation instructor. The curriculum uses principles of Mindfulness Based Stress Reduction and evidence based integrative medicine. The visit is structured similarly to other group medical visits. Data was gathered through four focus groups held after the cohorts were completed. Participants (N=20) were largely low income minority adults with chronic pain and comorbid depression. Six themes emerged from the coding including: chronic pain is isolating; group treatment contributes to better coping with pain; loss of control and autonomy because of the unpredictability of pain as well as dependence on medication and frequent medical appointments; groups improve agency and control over one's health condition; navigating the healthcare system and unsatisfactory treatment options; and changes after the IMGV due to non-pharmacological health management. The IMGV is a promising format of delivering integrative care for chronic pain and depression which addresses many of the problems identified by patients in usual care. Copyright © 2017 Elsevier Ltd.

Focus group data were generated by a larger, mixed-methods investigation on treatment practices among therapists working with significantly traumatized populations in a primarily rural, underdeveloped region of the USA. This paper explores reasons behind low utilization of evidence-based practices (EBPs) that putatively would benefit poor communities where these behavioural health care providers serve. Eight focus groups of 45 licensed and certified behavioural health professionals were conducted over a 6-month period of time in 2006. Sites were selected based on Beale code designations with representation from urban, rural, and rural with urban influence providers. Potential respondents were selected from licensing board membership rosters and invited to participate in the study. Focus groups were facilitated by trained interviewers using a semi-structured interview schedule that focused on how participants defined, assessed, and understood trauma, as well as the information therapists utilized to determine interventions for clients with trauma histories. Focus group transcripts were analysed using qualitative data reduction methods and six major themes emerged regarding the limited use of EBPs: complexity of trauma identification, issues with manualized assessment, role of treatment settings, conditions for innovation success and failure, untangling cultural effects, and defining successful treatment outcomes. These findings shed light on the endurance of insufficient behavioural health infrastructures despite therapists' access to scientifically validated treatments for trauma spectrum and co-morbid mental disorders suffered by children and adults. Such insights have implications for the success of global dissemination of validated behavioural health interventions. © 2010 Blackwell Publishing Ltd.

Community and neighbourhood structures contribute not only to the health and well-being, but also to the participation of older adults. The degree of participation depends on both the living environment and the individual's personal characteristics, preferences and perception. However, there is still limited empirical evidence on how community and neighbourhood structures are linked to participation and health in the aged population. A qualitative exploratory approach was chosen with a series of problem-centred, semi-structured focus group discussions. Study participants were selected from within the city of Augsburg, Southern Germany, and from two municipalities in surrounding rural districts. The interviews took place in 2013. Structuring content analysis was used to identify key concepts. We conducted 11 focus group discussions with a total of 78 different study participants. The study participants (33 men and 45 women) had a mean age of 74 years (range 65-92 years). Only two study participants lived in an assisted living facility. Of all study participants, 77% lived in urban and 23% in rural areas. We extracted four metacodes ('Usual activities', 'Requirements for participation', 'Barriers to participation' and 'Facilitators for participation') and 15 subcodes. Health and poorly designed infrastructure were mentioned as important barriers to participation, and friendship and neighbourhood cohesion as important facilitators. This qualitative study revealed that poor design and accessibility of municipal infrastructure are major barriers to participation in old age in Germany. Community and neighbourhood structures can be part of the problem but also part of the solution when accessibility and social networks are taken into account.

Background Tourism areas represent ecologies of heightened HIV vulnerability characterized by a disproportionate concentration of alcohol venues. Limited research has explored how alcohol venues facilitate HIV transmission. Methods We spatially mapped locations of alcohol venues in a Dominican tourism town and conducted a venue-based survey of key informants (n=135) focused on three facets of alcohol venues: structural features, type of patrons, and HIV risk behaviors. Using latent class analysis, we identified evidence-based typologies of alcohol venues for each of the three facets. Focused contrasts identified the co-occurrence of classes of structural features, classes of types of patrons, and classes of HIV risk behavior, thus elaborating the nature of high risk venues. Results We identified three categories of venue structural features, three for venue patrons, and five for HIV risk behaviors. Analysis revealed that alcohol venues with the greatest structural risks (e.g., sex work on site with lack of HIV prevention services) were most likely frequented by the venue patron category characterized by high population-mixing between locals and foreign tourists, who were in turn most likely to engage in the riskiest behaviors. Conclusion Our results highlight the stratification of venue patrons into groups who engage in behaviors of varying risk in structural settings that vary in risk. The convergence of high-risk patron groups in alcohol venues with the greatest structural risk suggests these locations have potential for HIV transmission. Policymakers and prevention scientists can use these methods and data to target HIV prevention resources to identified priority areas. PMID:23478154

Purpose To better understand health-related decision making among overweight and obese emerging adults. Design and Methods A cross-sectional design was used in the parent study involving overweight and obese emerging adults, ages 18–29 years. The goal of the parent study was to screen participants’ diabetes risk and identify characteristics of emerging adults with prediabetes (N = 107). A sub-sample of respondents (n = 34) from the parent study were invited to participate in focus group interviews depending on whether they had prediabetes (three groups) or they did not have prediabetes (four groups). Each focus group interview lasted 90–120 minutes following a semi-structured interview guide. Conventional content analysis was used in the data analysis. Because of the similarities between participants with and without prediabetes, the findings were synthesized and reported in the aggregate. Moreover, during the analysis, the authors decided that Rational Choice Theory provided a useful organizing structure for presenting the data. Results Emerging adults’ behavioral decisions were rational reactions to their personal competence, perception of health, environment, and availability of resources to handle problems. Trade-offs calculation and estimations of resource availability were often used when making decisions. Conclusions Emerging adults choose unhealthy behaviors due to inaccurate information and insufficient competence to practice healthy lifestyles rather than because of laziness or being irrational.

Little is known about treatment for pregnant and postpartum women with co-occurring substance use and depression. Funded by the National Institute of Drug Abuse, we conducted three focus groups with 18 pregnant and postpartum women in 2011 at an urban substance use treatment clinic. A semi-structured discussion guide probed for factors impacting treatment outcomes and needs. Data were analyzed using grounded theory. Women identified motivational, family, friend, romantic, and agency characteristics as facilitative or challenging to their recoveries, and desired structure (group treatment, a safe environment, transportation) and content (attention to mental health, family, and gender-specific issues) of treatment.

In Hong Kong, statutory regulation for traditional Chinese medicine (TCM) practitioners has been implemented in the past decade. Increasing use of TCM on top of biomedicine (BM) services by the population has been followed; but corresponding policy development to integrate their practices has not yet been discussed. Using focus group methodology, we explore policy ideas for integration by collating views from frontline BM (n = 50) and TCM clinicians (n = 50). Qualitative data were analyzed under the guidance of structuration model of collaboration, a theoretical model for understanding interprofessional collaboration. From focus group findings we generated 28 possible approaches, and subsequently their acceptability was assessed by a two round Delphi survey amongst BM and TCM policy stakeholders (n = 12). Consensus was reached only on 13 statements. Stakeholders agreed that clinicians from both paradigms should share common goals of providing patient-centered care, promoting the development of protocols for shared care and information exchange, as well as strengthening interprofessional connectivity and leadership for integration. On the other hand, attitudes amongst policy stakeholders were split on the possibility of fostering trust and mutual learning, as well as on enhancing innovation and governmental support. Future policy initiatives should focus on these controversial areas. PMID:22649469

Toxmatch-a new software tool to aid in the development and evaluation of chemically similar groups.

PubMed

Patlewicz, G; Jeliazkova, N; Gallegos Saliner, A; Worth, A P

2008-01-01

Chemical similarity is a widely used concept in toxicology, and is based on the hypothesis that similar compounds should have similar biological activities. This forms the underlying basis for performing read-across, forming chemical groups and developing (Quantitative) Structure-Activity Relationships ((Q)SARs). Chemical similarity is often perceived as structural similarity but in fact there are a number of other approaches that can be used to assess similarity. A systematic similarity analysis usually comprises two main steps. Firstly the chemical structures to be compared need to be characterised in terms of relevant descriptors which encode their physicochemical, topological, geometrical and/or surface properties. A second step involves a quantitative comparison of those descriptors using similarity (or dissimilarity) indices. This work outlines the use of chemical similarity principles in the formation of endpoint specific chemical groupings. Examples are provided to illustrate the development and evaluation of chemical groupings using a new software application called Toxmatch that was recently commissioned by the European Chemicals Bureau (ECB), of the European Commission's Joint Research Centre. Insights from using this software are highlighted with specific focus on the prospective application of chemical groupings under the new chemicals legislation, REACH.

Building Knowledge Structures by Testing Helps Children With Mathematical Learning Difficulty.

Zhang, Yiyun; Zhou, Xinlin

2016-01-01

Mathematical learning difficulty (MLD) is prevalent in the development of mathematical abilities. Previous interventions for children with MLD have focused on number sense or basic mathematical skills. This study investigated whether mathematical performance of fifth grade children with MLD could be improved by developing knowledge structures by testing using a web-based curriculum learning system. A total of 142 children with MLD were recruited; half of the children were in the experimental group (using the system), and the other half were in the control group (not using the system). The children were encouraged to use the web-based learning system at home for at least a 15-min session, at least once a week, for one and a half months. The mean accumulated time of testing on the system for children in the experimental group was 56.2 min. Children in the experimental group had significantly higher scores on their final mathematical examination compared to the control group. The results suggest that web-based curriculum learning through testing that promotes the building of knowledge structures for a mathematical course was helpful for children with MLD. © Hammill Institute on Disabilities 2014.

2012-01-01

Objectives: Limited human resources are widely recognised as a barrier to achieve health-related Millennium Development Goals. Availability of medical supplies and suitably trained health personnel are crucial to ensuring a well-functioning medical supply system. The objective of this paper is to identify the factors which influence the availability of medical supplies within the health facilities of Vanuatu. Methods: A qualitative triangulated strategy using semi-structured interviews, observational workplace surveys and semi-structured focus groups was developed. This research was approved by the Human Ethics Committee of the University of Canberra and was funded through a direct grant from the United Nations Population Fund Suva, Pacific sub regional office. Results: During two weeks of data collection, 21 interviews were conducted, observational workplace surveys were completed in 19 facilities and 22 personnel participated in three focus groups across three provinces. The interviewees had a wide range of primary professional groupings and were representative of the Vanuatu health workforce. A complex array of medical supply issues are described from within the three tiered structure of the medical supply system. Conclusion: The results of this research have further informed our understanding of the competencies required by healthcare personnel to conduct medical supply management activities effectively in Pacific Island countries. As a result of this research, a platform is provided for the government of Vanuatu to engage development partners to work toward a sustainable medical supply system. PMID:23093895

The number of people with multiple chronic conditions receiving primary care services is growing. To deal with their increasingly complex health care demands, professionals from different disciplines need to collaborate. Interprofessional team (IPT) meetings are becoming more popular. Several studies describe important factors related to conducting IPT meetings, mostly from a professional perspective. However, in the light of patient-centeredness, it is valuable to also explore the patients' perspective. The aim was to explore the patients' perspectives regarding IPT meetings in primary care. A qualitative study with a focus group design was conducted in the Netherlands. Two focus group meetings took place, for which the same patients were invited. The participants, chronically ill patients with experience on interprofessional collaboration, were recruited through the regional patient association. Participants discussed viewpoints, expectations, and concerns regarding IPT meetings in two rounds, using a focus group protocol and selected video-taped vignettes of team meetings. The first meeting focused on conceptualization and identification of themes related to IPT meetings that are important to patients. The second meeting aimed to gain more in-depth knowledge and understanding of the priorities. Discussions were audio-taped and transcribed verbatim, and analyzed by means of content analysis. The focus group meetings included seven patients. Findings were divided into six key categories, capturing the factors that patients found important regarding IPT meetings: (1) putting the patient at the center, (2) opportunities for patients to participate, (3) appropriate team composition, (4) structured approach, (5) respectful communication, and (6) informing the patient about meeting outcomes. Patients identified different elements regarding IPT meetings that are important from their perspective. They emphasized the right of patients or their representatives to take part in IPT meetings. Results of this study can be used to develop tools and programs to improve interprofessional collaboration.

MODY - calculation of ordered structures by symmetry-adapted functions

Białas, Franciszek; Pytlik, Lucjan; Sikora, Wiesława

2016-01-01

In this paper we focus on the new version of computer program MODY for calculations of symmetryadapted functions based on the theory of groups and representations. The choice of such a functional frame of coordinates for description of ordered structures leads to a minimal number of parameters which must be used for presentation of such structures and investigations of their properties. The aim of this work is to find those parameters, which are coefficients of a linear combination of calculated functions, leading to construction of different types of structure ordering with a given symmetry. A spreadsheet script for simplification of this work has been created and attached to the program.

Development of a prototype clinical decision support tool for osteoporosis disease management: a qualitative study of focus groups.

Osteoporosis affects over 200 million people worldwide, and represents a significant cost burden. Although guidelines are available for best practice in osteoporosis, evidence indicates that patients are not receiving appropriate diagnostic testing or treatment according to guidelines. The use of clinical decision support systems (CDSSs) may be one solution because they can facilitate knowledge translation by providing high-quality evidence at the point of care. Findings from a systematic review of osteoporosis interventions and consultation with clinical and human factors engineering experts were used to develop a conceptual model of an osteoporosis tool. We conducted a qualitative study of focus groups to better understand physicians' perceptions of CDSSs and to transform the conceptual osteoporosis tool into a functional prototype that can support clinical decision making in osteoporosis disease management at the point of care. The conceptual design of the osteoporosis tool was tested in 4 progressive focus groups with family physicians and general internists. An iterative strategy was used to qualitatively explore the experiences of physicians with CDSSs; and to find out what features, functions, and evidence should be included in a working prototype. Focus groups were conducted using a semi-structured interview guide using an iterative process where results of the first focus group informed changes to the questions for subsequent focus groups and to the conceptual tool design. Transcripts were transcribed verbatim and analyzed using grounded theory methodology. Of the 3 broad categories of themes that were identified, major barriers related to the accuracy and feasibility of extracting bone mineral density test results and medications from the risk assessment questionnaire; using an electronic input device such as a Tablet PC in the waiting room; and the importance of including well-balanced information in the patient education component of the osteoporosis tool. Suggestions for modifying the tool included the addition of a percentile graph showing patients' 10-year risk for osteoporosis or fractures, and ensuring that the tool takes no more than 5 minutes to complete. Focus group data revealed the facilitators and barriers to using the osteoporosis tool at the point of care so that it can be optimized to aid physicians in their clinical decision making.

2018-02-01

We study the entanglement for a state on linked torus boundaries in 3 d Chern-Simons theory with a generic gauge group and present the asymptotic bounds of Rényi entropy at two different limits: (i) large Chern-Simons coupling k, and (ii) large rank r of the gauge group. These results show that the Rényi entropies cannot diverge faster than ln k and ln r, respectively. We focus on torus links T (2 , 2 n) with topological linking number n. The Rényi entropy for these links shows a periodic structure in n and vanishes whenever n = 0 (mod p), where the integer p is a function of coupling k and rank r. We highlight that the refined Chern-Simons link invariants can remove such a periodic structure in n.

The present study of women with substance use disorders used grounded theory to examine women’s experiences in both the Women’s Recovery Group (WRG) and a mixed-gender Group Drug Counseling (GDC). Semi-structured interviews were completed in 2005 by twenty-eight women in a U.S. metropolitan area. Compared to GDC, women in WRG more frequently endorsed feeling safe, embracing all aspects of one’s self, having their needs met, feeling intimacy, empathy, and honesty. Additionally, group cohesion and support allowed women to focus on gender-relevant topics supporting their recovery. These advantages of single gender group therapy can increase treatment satisfaction and improve treatment outcomes. PMID:23607675

The program was rounded up by working group and plenum discussions culminating in a Workshop report emphasizing problem areas, gaps in the data base and recommendations for future research.

Composite Dry Structure Cost Improvement Approach

Nettles, Alan; Nettles, Mindy

2015-01-01

This effort demonstrates that by focusing only on properties of relevance, composite interstage and shroud structures can be placed on the Space Launch System vehicle that simultaneously reduces cost, improves reliability, and maximizes performance, thus providing the Advanced Development Group with a new methodology of how to utilize composites to reduce weight for composite structures on launch vehicles. Interstage and shroud structures were chosen since both of these structures are simple in configuration and do not experience extreme environments (such as cryogenic or hot gas temperatures) and should represent a good starting point for flying composites on a 'man-rated' vehicle. They are used as an example only. The project involves using polymer matrix composites for launch vehicle structures, and the logic and rationale behind the proposed new methodology.

Cruz, Gustavo D.; Shulman, Lawrence C.; Kumar, Jayanth V.; Salazar, Christian R.

2007-01-01

New York City (NYC) has one of the highest incidence and mortality rates of oral and pharyngeal cancer (OPC) for Hispanics of any major U.S. city. This qualitative assessment explores OPC awareness, attitudes, and screening practices among at-risk Hispanics, health care providers, and community leaders in a Hispanic neighborhood of NYC. Four focus groups (N=39) were conducted with at-risk Hispanics. Structured interviews were conducted with ten health care providers (four physicians, four dentists, two dental hygienists) and three key community leaders. Results showed major gaps in OPC awareness across all key stakeholders. Focus group participants expressed difficulty in accessing appropriate health care. Health care providers were not familiar with OPC prevention and early detection practices. Community leaders lacked the knowledge and resources necessary for advocating prevention and early detection for their constituencies. All participants reported cultural, social, and structural barriers to prevention. There is a need for developing a comprehensive, culturally competent health communication program that targets all key stakeholders in the at-risk Hispanic community of NYC. PMID:17982210

Regular exercise is recommended to mitigate the adverse effects of androgen deprivation therapy in men with prostate cancer. The purpose of this study was to explore the experience of transition to unsupervised, community-based exercise among men who had participated in a hospital-based supervised exercise programme in order to propose components that supported transition to unsupervised exercise. Participants were selected by means of purposive, criteria-based sampling. Men undergoing androgen deprivation therapy who had completed a 12-week hospital-based, supervised, group exercise intervention were invited to participate. The programme involved aerobic and resistance training using machines and included a structured transition to a community-based fitness centre. Data were collected by means of semi-structured focus group interviews and analysed using thematic analysis. Five focus group interviews were conducted with a total of 29 men, of whom 25 reported to have continued to exercise at community-based facilities. Three thematic categories emerged: Development and practice of new skills; Establishing social relationships; and Familiarising with bodily well-being. These were combined into an overarching theme: From learning to doing. Components suggested to support transition were as follows: a structured transition involving supervised exercise sessions at a community-based facility; strategies to facilitate peer support; transferable tools including an individual exercise chart; and access to 'check-ups' by qualified exercise specialists. Hospital-based, supervised exercise provides a safe learning environment. Transferring to community-based exercise can be experienced as a confrontation with the real world and can be eased through securing a structured transition, having transferable tools, sustained peer support and monitoring.

Exploring the role of cognitive and structural forms of social capital in HIV/AIDS trends in the Kagera region of Tanzania - a grounded theory study.

PubMed

Frumence, Gasto; Eriksson, Malin; Nystrom, Lennarth; Killewo, Japhet; Emmelin, Maria

2011-04-01

The article presents a synthesis of data from three village case studies focusing on how structural and cognitive social capital may have influenced the progression of the HIV epidemic in the Kagera region of Tanzania. Grounded theory was used to develop a theoretical model describing the possible links between structural and cognitive social capital and the impact on sexual health behaviours. Focus group discussions and key informant interviews were carried out to represent the range of experiences of existing social capital. Both structural and cognitive social capital were active avenues for community members to come together, empower each other, and develop norms, values, trust and reciprocal relations. This empowerment created an enabling environment in which members could adopt protective behaviours against HIV infection. On the one hand, we observed that involvement in formal and informal organisations resulted in a reduction of numbers of sexual partners, led people to demand abstinence from sexual relations until marriage, caused fewer opportunities for casual sex, and gave individuals the agency to demand the use of condoms. On the other hand, strict membership rules and regulations excluded some members, particularly excessive alcohol drinkers and debtors, from becoming members of the social groups, which increased their vulnerability in terms of exposure to HIV. Social gatherings (especially those organised during the night) were also found to increase youths' risk of HIV infection through instances of unsafe sex. We conclude that even though social capital may at times have negative effects on individuals' HIV-prevention efforts, this study provides initial evidence that social capital is largely protective through empowering vulnerable groups such as women and the poor to protect against HIV infection and by promoting protective sexual behaviours.

The Acquisition of English Focus Marking by Non-Native Speakers

NASA Astrophysics Data System (ADS)

Baker, Rachel Elizabeth

This dissertation examines Mandarin and Korean speakers' acquisition of English focus marking, which is realized by accenting particular words within a focused constituent. It is important for non-native speakers to learn how accent placement relates to focus in English because appropriate accent placement and realization makes a learner's English more native-like and easier to understand. Such knowledge may also improve their English comprehension skills. In this study, 20 native English speakers, 20 native Mandarin speakers, and 20 native Korean speakers participated in four experiments: (1) a production experiment, in which they were recorded reading the answers to questions, (2) a perception experiment, in which they were asked to determine which word in a recording was the last prominent word, (3) an understanding experiment, in which they were asked whether the answers in recorded question-answer pairs had context-appropriate prosody, and (4) an accent placement experiment, in which they were asked which word they would make prominent in a particular context. Finally, a new group of native English speakers listened to utterances produced in the production experiment, and determined whether the prosody of each utterance was appropriate for its context. The results of the five experiments support a novel predictive model for second language prosodic focus marking acquisition. This model holds that both transfer of linguistic features from a learner's native language (L1) and features of their second language (L2) affect learners' acquisition of prosodic focus marking. As a result, the model includes two complementary components: the Transfer Component and the L2 Challenge Component. The Transfer Component predicts that prosodic structures in the L2 will be more easily acquired by language learners that have similar structures in their L1 than those who do not, even if there are differences between the L1 and L2 in how the structures are realized. The L2 Challenge Component predicts that for difficult tasks, language learners will rely on widely-applied prosodic patterns, making them more successful at prosodically marking broad focus than narrow focus. However, for easy tasks, language learners will more successfully mark information structures that have a more direct relationship between focus and accent placement.

2015-06-01

To explore the perspectives of women, female relatives, and healthcare providers on labor companionship. In a qualitative study, data were collected from women giving birth, female family members, and healthcare staff via semi-structured interviews in three large public teaching hospitals in Beirut (Lebanon), Damascus (Syria), and Mansoura (Egypt) between May and December 2012. Focus groups were conducted with midwives, nurses, and medical residents. Data were assessed by thematic analysis. A total of 69 women, 57 female relatives, and 28 obstetricians were interviewed, and two focus groups discussions occurred. Women reported that being alone during labor raises feelings of fear and anxiety. They reported appreciating professional support, but found comfort in the psychological support offered by family members during labor. Midwives and nurses pointed to structural factors related to the organization of care and to the marginalization of their role as barriers to implementing best practices. Obstetricians referred to the absence of prenatal education classes, and social norms as factors impeding the organization of labor support initiatives. Implementing labor companionship can improve women's childbirth experiences and outcomes. Organizational structural barriers and non-supportive providers' attitudes need to be addressed to influence hospital practices.

'Life under the tent is not safe, especially for young women': understanding intersectional violence among internally displaced youth in Leogane, Haiti.

PubMed

Logie, Carmen H; Daniel, CarolAnn; Ahmed, Uzma; Lash, Rebecca

Haiti's 2010 earthquake devastated social, health, and economic infrastructure and left 2 million persons homeless. Over 6 years later 61,000 people remain displaced, most lacking protection, services, and durable solutions. Structural contexts elevate risks of gender-based violence (GBV) targeting internally displaced (ID) girls and women. We used an intersectionality framework to explore lived experiences and understanding of violence among ID young men and women in Leogane, Haiti. We conducted six focus groups, three with ID young women (n = 30) and three with ID young men (n = 30) aged 18-24 years, and 11 in-depth individual interviews with frontline workers in Leogane. Focus groups and interviews were conducted in Kreyol, transcribed verbatim, translated into English, and analyzed using narrative thematic techniques. Findings revealed violence experienced by ID youth was (re)produced at the intersection of gender, poverty, displacement, and age. Multi-level forms of violence included structural (e.g. poverty), community (e.g. gender norms, and interpersonal (e.g. family expectations) dimensions. Coping strategies spanned intrapersonal (hope), community (social support), and structural (employment/education) dimensions. Interventions to reduce violence should be tailored to address the social inequities that emerge at the intersection of youth, poverty, displacement, and hegemonic gender norms.

The effects of partnership between Schizophrenics Anonymous (SA, a mutual-help organization) and the Mental Health Association in Michigan (MHAM, a professionally staffed advocacy organization) on SA's growth and development were explored. Following the initiation of a formal partnership, SA groups were more available throughout the state, more likely to be associated with formal mental health settings, and less likely to have leaders who had been participants in other SA groups. Groups with consumer leaders had significantly greater longevity than groups with professional leaders. Changes in the organizational structure and process of SA were also identified. SA leaders reported that SA moved from a collective to a more bureaucratic structure. As a result, there was greater consistency, administrative capacity, and response capacity. This enhanced capacity came with costs reported by SA leaders. The leadership role of SA members became less defined. SA members expressed concerns about the more hierarchical structure of SA's organization, decreased consumer control, increased professional involvement in SA, and an excessive focus on group development as opposed to group maintenance. Mental Health Association in Michigan staff reported that MHAM was also impacted by the partnership, both with regard to internal functioning and external perception. Implications for effective partnerships between mutual-help and professional organizations are discussed.

Despite high HIV prevalence rates among most-at-risk groups, utilisation of HIV testing, treatment and care services was relatively low in Karnataka prior to 2008. The authors aimed to understand the barriers to and identify potential solutions for improving HIV service utilisation. Focus group discussions were carried out among homogeneous groups of female sex workers, men who have sex with men and transgenders, and programme peer educators in six districts across Karnataka in March and April 2008. 26 focus group discussions were conducted, involving 302 participants. Participants had good knowledge about HIV and HIV voluntary counselling and testing (VCT) services, but awareness of other HIV services was low. The fear of the psychological impact of a positive HIV test result and the perceived repercussions of being seen accessing HIV services were key personal and interpersonal barriers to HIV service utilisation. Previous experiences of discrimination at government healthcare services, coupled with discriminatory attitudes and behaviours by VCT staff, were key structural barriers to VCT service uptake among those who had not been HIV tested. Among those who had used government-managed prevention of parent to child transmission and antiretroviral treatment services, poor physical facilities, long waiting times, lack of available treatment, the need to give bribes to receive care and discriminatory attitudes of healthcare staff presented additional structural barriers. Embedding some HIV care services within existing programmes for vulnerable populations, as well as improving service quality at government facilities, are suggested to help overcome the multiple barriers to service utilisation. Increasing the uptake of HIV testing, treatment and care services is key to improving the quality and longevity of the lives of HIV-infected individuals.

'I don't need an eye for an eye': Women's responses to intimate partner violence in Sierra Leone and Liberia.

Horn, Rebecca; Puffer, Eve S; Roesch, Elisabeth; Lehmann, Heidi

2016-01-01

This paper explores the possibilities for agency in intimate partner violence (IPV) situations from the perspective of women in Sierra Leone and Liberia using focus group discussions (N groups = 14, N participants = 110) and individual interviews (N = 20). Findings identify multiple interrelated factors influencing the decision-making of women experiencing IPV. At the individual level, emotional factors and women's knowledge of their rights and options influence their decision-making. At the relational level, the role of neighbours, family and friends is crucial, both for emotional support and practical assistance. At the community level, more formal structures play a role, such as chiefs and women's groups, though their effectiveness varies. At the structural level are barriers to effective responses, including a poorly functioning criminal justice system and a social system in which children often stay with fathers following separation or divorce. Strong cultural beliefs operate to keep women in abusive relationships. We identify implications for prevention and response services and make practice recommendations. Since the desire of most women experiencing IPV was to live in peace with their husbands, interventions should respect women's priorities by focusing more on prevention and interventions to end the violence, rather than solely assisting women to leave violent relationships.

A critical examination of the construct of perfectionism and its relationship to mental health in Asian and African Americans using a cross-cultural framework.

DiBartolo, Patricia Marten; Rendón, María José

2012-04-01

Although the bulk of the research literature on the construct of perfectionism and its relationship to mental health in the last 20 years has focused predominantly on Caucasian American samples, researchers are paying increasing attention to understanding perfectionism's dimensions across ethnicities. Given this momentum, the purpose of this paper is to use a cross-cultural framework to review published studies assessing perfectionism in members of an ethnic minority group living in the United States. Research to date has focused exclusively on Asian and African American samples and we organize our review by separating this literature into those studies that use level and structure-oriented cross-cultural approaches. Structure-oriented approaches empirically explore the phenomenology and/or correlates of perfectionism within each ethnic group whereas level-oriented approaches examine the relative magnitude of perfectionism's levels across groups. The last section of the review critically examines the strength of the evidence in support of researchers' arguments that certain sociocultural factors, such as collectivism and parenting style, influence perfectionism's expression and implications for ethnic minorities. Throughout the review, we offer a series of steps researchers can take to foster our understanding of perfectionism and its impacts using a cross-cultural perspective. Copyright © 2011 Elsevier Ltd.

This article aims to explore quality improvement (QI) at individual, group and organisational level. It also aims to identify restraining forces using formative evaluation and discuss implications for current UK policy, particularly quality, innovation, productivity and prevention. Learning events combined with work-based projects, focusing on individual and group responses are evaluated. A total of 11 multi-disciplinary groups drawn from NHS England healthcare Trusts (self-governing operational groups) were sampled. These Trusts have different geographic locations and participants were drawn from primary, secondary and commissioning arms. Mixed methods: questionnaires, observations and reflective accounts were used. The paper finds that solution versus problem identification causes confusion and influences success. Time for problem solving to achieve QI was absent. Feedback and learning structures are often not in place or inflexible. Limited focus on patient-centred services may be related to past assumptions regarding organisational design, hence assumptions and models need to be understood and challenged. The authors revise the Plan, Do, Study; Act (PDSA) model by adding an explicit problem identification step and hence avoiding solution-focused habits; demonstrating the need for more formative evaluations to inform managers and policy makers about healthcare QI processes. - Although UK-centric, the quality agenda is a USA and European theme, findings may help those embarking on this journey or those struggling with QI.

A century of work teams in the Journal of Applied Psychology.

2017-03-01

Work groups are a vital link between individuals and organizations. Systematic psychological research on the nature and effects of work groups dates back at least to the Hawthorne studies of the 1920s and 1930s. Yet little to none of this work appeared in the Journal of Applied Psychology until the 1950s when groups were treated primarily as foils against which to compare the performance of individuals. From the 1990s to the present, the volume of research and the nature of topics addressing work group/teams expanded significantly. The authors review the evolution of team research over the past century with a particular focus on that which has appeared in this journal. They chronicle the shift from a focus on individuals within teams, or on individual versus team comparisons, to a focus on the team itself and larger systems of teams. They describe the major outcomes studied within this literature, and how they relate to the nature of team tasks and structures. Further, the authors consider the roles of team members' characteristics and composition, and team dynamics in terms of processes and emergent states. They close with a call for future research that models dynamic team relationships in context and as they operate in complex systems. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Collaborative diagramming during problem based learning in medical education: Do computerized diagrams support basic science knowledge construction?

PubMed

De Leng, Bas; Gijlers, Hannie

2015-05-01

To examine how collaborative diagramming affects discussion and knowledge construction when learning complex basic science topics in medical education, including its effectiveness in the reformulation phase of problem-based learning. Opinions and perceptions of students (n = 70) and tutors (n = 4) who used collaborative diagramming in tutorial groups were collected with a questionnaire and focus group discussions. A framework derived from the analysis of discourse in computer-supported collaborative leaning was used to construct the questionnaire. Video observations were used during the focus group discussions. Both students and tutors felt that collaborative diagramming positively affected discussion and knowledge construction. Students particularly appreciated that diagrams helped them to structure knowledge, to develop an overview of topics, and stimulated them to find relationships between topics. Tutors emphasized that diagramming increased interaction and enhanced the focus and detail of the discussion. Favourable conditions were the following: working with a shared whiteboard, using a diagram format that facilitated distribution, and applying half filled-in diagrams for non-content expert tutors and\\or for heterogeneous groups with low achieving students. The empirical findings in this study support the findings of earlier more descriptive studies that diagramming in a collaborative setting is valuable for learning complex knowledge in medicine.

Objective To explore GPs’ experiences using cognitive behavioural therapy (CBT), with a focus on factors that promote or limit the use of CBT in general practice. Design Qualitative study using data from written evaluation reports and focus-group interviews. Setting Norwegian general practice. Subjects GPs who participated in a longitudinal CBT course in the continuous medical education (CME) programme for GPs in Norway, of whom 19 filled in evaluation forms and 15 participated in focus-group interviews. Main outcome measures Experiences with the use of CBT in general practice. Results GPs used CBT mainly in the treatment of patients with anxiety disorders and depression. Factors that promoted the use of CBT in general practice were structured supervision and group counselling, receiving feedback on individual video-recorded consultations, and experiencing that one mastered the therapeutic techniques. Limiting factors were that it took some time before one mastered the techniques, lack of eligible patients, constraints related to attending group supervision during office hours, and the lack of financial incentives to use CBT in general practice. Conclusion Tailored training programmes in CBT for GPs may contribute to more frequent use of CBT in general practice. A formal recognition of CBT in the reimbursement scheme for GPs might counter limiting factors to an increased use of CBT in general practice. PMID:21861599

Widespread reports of high stress levels and mental health problems among university student populations indicate the use of interventions to facilitate stress reduction and support student resilience and wellbeing. There is growing evidence that regular mindfulness practice may confer positive health benefits and reduced stress levels. The aim of this pilot project was to explore the impact of a seven-week stress management and mindfulness program as a learning support and stress reduction method for nursing and midwifery students. The program was conducted at a large regional university in Australia. Fourteen first-year undergraduate nursing and midwifery students agreed to attend the program and to participate in a follow-up focus group. A descriptive qualitative design was utilised to examine the impact of the program. A semi-structured focus group interview was conducted with a thematic analysis undertaken of the transcript and process notes. Ten students completed the research component of this project by participating in the focus group interview. Three main themes capture the participants' experience: attending to self, attending to others and attending to program related challenges. Data indicate a positive impact on sleep, concentration, clarity of thought and a reduction in negative cognitions. Participants also identified challenges related to timetabling, program structure and venue. Overall, this pilot program enhanced the participants' sense of well-being. Despite the challenges, benefits were identified on a personal and professional level. Valuable feedback was provided that will be used to further develop and expand stress management and mindfulness programs offered to students attending this university. Copyright © 2014.

Sustaining enrollment in health insurance for vulnerable populations: lessons from Massachusetts.

Capoccia, Victor; Croze, Colette; Cohen, Martin; O'Brien, John P

2013-04-01

Since 2008 Massachusetts has had universal health insurance with an individual mandate. As a result, only about 3% of the population is uninsured. However, patients who use behavioral health services are uninsured at much higher rates. This 2011 study sought to understand reasons for the discrepancy and identify approaches to reduce disenrollment and sustain coverage. The qualitative study was based on structured interviews and focus groups. Structured interviews were conducted with 15 policy makers, consumer advocates, and chief executive officers of provider organizations, and three focus groups were held with 33 patient volunteers. The interviews and focus groups identified several disenrollment opportunities, all of which contribute to "churn" (the process by which disenrolled persons who remain eligible are reenrolled in the same or a different plan): missing and incomplete documentation, acute and chronic conditions and long-term disabilities that interfere with a patient's ability to respond to program communications, and lack of awareness among beneficiaries of the consequences of changes that trigger termination and the need to transfer to another program. Although safeguards are built into the system to avoid some disenrollments, the policies and procedures that drive the system are built on a default assumption of ineligibility or disenrollment until the individual establishes eligibility and completes requirements. Practices that can sustain enrollment include real-time Web-based prepopulated enrollment and redetermination processes, redetermination flexibility for designated chronic illnesses, and standardized performance metrics for churn and associated costs. Changes in the information system infrastructure and in outreach, enrollment, disenrollment, and reenrollment procedures can improve continuity and retention of health insurance coverage.

Patients suffering from age-related macular degeneration (AMD) are rarely actively involved in decision-making, despite facing preference-sensitive treatment decisions. This paper presents a qualitative study to prepare quantitative preference elicitation in AMD patients. The aims of this study were (1) to gain familiarity with and learn about the special requirements of the AMD patient population for quantitative data collection; and (2) to select/refine patient-relevant treatment attributes and levels, and gain insights into preference structures. Semi-structured focus group interviews were performed. An interview guide including preselected categories in the form of seven potentially patient-relevant treatment attributes was followed. To identify the most patient-relevant treatment attributes, a ranking exercise was performed. Deductive content analyses were done by two independent reviewers for each attribute to derive subcategories (potential levels of attributes) and depict preference trends. The focus group interviews included 21 patients. The interviews revealed that quantitative preference surveys in this population will have to be interviewer assisted to make the survey feasible for patients. The five most patient-relevant attributes were the effect on visual function [ranking score (RS): 139], injection frequency (RS: 101), approval status (RS: 83), side effects (RS: 79), and monitoring frequency (RS: 76). Attribute and level refinement was based on patients' statements. Preference trends and dependencies between attributes informed the quantitative instrument design. This study suggests that qualitative research is a very helpful step to prepare the design and administration of quantitative preference elicitation instruments. It especially facilitated familiarization with the target population and its preferences, and it supported attribute/level refinement.

Clinician-patient communication is central in palliative care, but it has not been described qualitatively which specific elements of communication are important for high-quality palliative care, particularly in the inpatient setting. Our aim was to identify elements of communication that are central to quality of care and satisfaction with care on palliative care units (PCUs), as described by inpatients, family caregivers, and health care providers. Qualitative interviews with patients/caregivers and focus groups with staff were conducted on four PCUs. Semi-structured interviews and focus groups elicited thoughts about the characteristics of satisfaction with care and quality of care for PCU inpatients and their family caregivers. Data were analyzed using a grounded theory method with an inductive, constant comparison approach; themes were coded to saturation. There were 46 interviews and eight focus groups. Communication was the most prevalent theme regarding satisfaction and quality of care, with five subthemes describing elements important to patients, caregivers, and staff. These included: 1) building rapport with patients and families to build trust and kinship; 2) addressing expectations and explaining goals of care; 3) keeping patients and families informed about the patient's condition; 4) listening actively to validate patients' concerns and individual needs; and 5) providing a safe space for conversations about death and dying. Patients, family caregivers, and health care providers affirmed that communication is a central element of quality of care and family satisfaction on PCUs. The five subthemes identified may serve as a structure for education and for quality improvement tools in palliative care inpatient settings.

BACKGROUND Physician disclosure of medical errors to institutions, patients, and colleagues is important for patient safety, patient care, and professional education. However, the variables that may facilitate or impede disclosure are diverse and lack conceptual organization. OBJECTIVE To develop an empirically derived, comprehensive taxonomy of factors that affects voluntary disclosure of errors by physicians. DESIGN A mixed-methods study using qualitative data collection (structured literature search and exploratory focus groups), quantitative data transformation (sorting and hierarchical cluster analysis), and validation procedures (confirmatory focus groups and expert review). RESULTS Full-text review of 316 articles identified 91 impeding or facilitating factors affecting physicians' willingness to disclose errors. Exploratory focus groups identified an additional 27 factors. Sorting and hierarchical cluster analysis organized factors into 8 domains. Confirmatory focus groups and expert review relocated 6 factors, removed 2 factors, and modified 4 domain names. The final taxonomy contained 4 domains of facilitating factors (responsibility to patient, responsibility to self, responsibility to profession, responsibility to community), and 4 domains of impeding factors (attitudinal barriers, uncertainties, helplessness, fears and anxieties). CONCLUSIONS A taxonomy of facilitating and impeding factors provides a conceptual framework for a complex field of variables that affects physicians' willingness to disclose errors to institutions, patients, and colleagues. This taxonomy can be used to guide the design of studies to measure the impact of different factors on disclosure, to assist in the design of error-reporting systems, and to inform educational interventions to promote the disclosure of errors to patients.

Norwegian nursing and medical students’ perception of interprofessional teamwork: a qualitative study

PubMed Central

2014-01-01

Background Little is known about the ways in which nursing and medical students perceive and understand their roles in interprofessional teamwork. A 2010 report by the World Health Organization highlights the importance of students’ understanding of teamwork in healthcare, and their ability to be effective team players. This study aims at describing nursing and medical students’ perceptions of interprofessional teamwork, focusing on experiences and recommendations that can be used to guide future educational efforts. Methods The study uses a qualitative research design. Data were collected from four focus group interviews: two homogenous groups (one with medical students, one with nursing students) and two mixed groups (medical and nursing students). Results The results show that traditional patterns of professional role perception still prevail and strongly influence students’ professional attitudes about taking responsibility and sharing responsibility across disciplinary and professional boundaries. It was found that many students had experienced group cultures detrimental to team work. Focusing on clinical training, the study found a substantial variation in perception with regard to the different arenas for interprofessional teamwork, ranging from arenas with collaborative learning to arenas characterized by distrust, confrontation, disrespect and hierarchical structure. Conclusions This study underlines the importance of a stronger focus on interprofessional teamwork in health care education, particularly in clinical training. The study results suggest that the daily rounds and pre-visit “huddles,” or alternatively psychiatric wards, offer arenas suitable for interprofessional training, in keeping with the students’ assessments and criteria proposed in previous studies.

In order to study problems of individuals with Autism Spectrum Disorders (ASD) with morphosyntax, we investigated twenty high-functioning Greek-speaking children (mean age: 6;11) and twenty age- and language-matched typically developing children on environments that allow or forbid object clitics or their corresponding noun phrase. Children with ASD fell behind typically developing children in comprehending and producing simple clitics and producing noun phrases in focus structures. The two groups performed similarly in comprehending and producing clitics in clitic left dislocation and in producing noun phrases in non-focus structures. We argue that children with ASD have difficulties at the interface of (morpho)syntax with pragmatics and prosody, namely, distinguishing a discourse prominent element, and considering intonation relevant for a particular interpretation that excludes clitics.

Peer assessment and feedback is encouraged to enhance students' learning. The aim of this study was to quantitatively and qualitatively analyse pre-clinical and clinical dental students' written peer feedback provided as part of a continuous, formative and structured peer assessment protocol. A total of 309 Year-2 and Year-5 dental students were invited to participate in a peer assessment and peer feedback protocol. Consenting volunteer students were trained to observe each other whilst working in the skills laboratory (Year-2) and in the dental clinic (Year-5). Subsequently, they followed a structured protocol of peer assessment and peer feedback using specially designed work-based forms during a complete academic year. The content of their written feedback was coded according to the UK General Dental Council domain, sign (positive or negative), specificity (task specific or general), and grouped into themes. A total of 108 participants (40 Year-2 and 68 Year-5) completed 1169 peer assessment work-based forms (516 pre-clinical and 653 clinical); 94% contained written feedback. The large majority (82%) of Year-2 feedback represented the clinical domain, 89% were positive, 77% were task specific, and they were grouped into 14 themes. Year-5 feedback was related mostly to Management and Leadership (37%) and Communication (32%), 64% were positive, 75% task specific, and they were clustered into 24 themes. The content of the feedback showed notable differences between Year-2 and Year-5 students. Senior students focused more on Communication and Management and Leadership skills, whilst juniors were more concerned with clinical skills. Year-5 students provided 13% negative feedback compared to only 2% from Year-2. Regulatory focus theory is discussed to explain these differences. Both groups provided peer feedback on a wide and different range of themes. However, four themes emerged in both groups: efficiency, infection control, time management and working speed. A structured peer assessment framework can be used to guide pre-clinical and clinical students to provide peer feedback focused on different domains, and on contrasting signs and specificities. It can also present an opportunity to complement tutors' feedback. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

What drives technology-based distractions? A structural equation model on social-psychological factors of technology-based driver distraction engagement.

2016-06-01

With the proliferation of new mobile and in-vehicle technologies, understanding the motivations behind a driver's voluntary engagement with such technologies is crucial from a safety perspective, yet is complex. Previous literature either surveyed a large number of distractions that may be diverse, or too focuses on one particular activity, such as cell phone use. Further, earlier studies about social-psychological factors underlying driver distraction tend to focus on one or two factors in-depth, and those that examine a more comprehensive set of factors are often limited in their analyses methods. The present work considers a wide array of social-psychological factors within a structural equation model to predict their influence on a focused set of technology-based distractions. A better understanding of these facilitators can enhance the design of distraction mitigation strategies. We analysed survey responses about three technology-based driver distractions: holding phone conversations, manually interacting with cell phones, and adjusting the settings of in-vehicle technology, as well as responses on five social-psychological factors: attitude, descriptive norm, injunctive norm, technology inclination, and a risk/sensation seeking personality. Using data collected from 525 drivers (ages: 18-80), a structural equation model was built to analyse these social-psychological factors as latent variables influencing self-reported engagement in these three technology-based distractions. Self-reported engagement in technology-based distractions was found to be largely influenced by attitudes about the distractions. Personality and social norms also played a significant role, but technology inclination did not. A closer look at two age groups (18-30 and 30+) showed that the effect of social norms, especially of injunctive norm (i.e., perceived approvals), was less prominent in the 30+ age group, while personality remained a significant predictor for the 30+ age group but marginally significant for the younger group. Findings from this work provide insights into the social-psychological factors behind intentional engagement in technology-based distractions and in particular suggesting that these factors may be sensitive to demographic differences.

Advancing Research on Structural Stigma and Sexual Orientation Disparities in Mental Health Among Youth.

Hatzenbuehler, Mark L

2017-01-01

Psychological research on stigma has focused largely on the perceptions of stigmatized individuals and their interpersonal interactions with the nonstigmatized. This work has been critical in documenting many of the ways in which stigma operates to harm those who are targeted. However, this research has also tended to overlook broader structural forms of stigma, which refer to societal-level conditions, cultural norms, and institutional policies and practices that constrain the lives of the stigmatized. In this article I describe the emerging field of research on structural stigma and review evidence documenting the harmful consequences of structural stigma for the mental/behavioral health of lesbian, gay, and bisexual youth. This research demonstrates that structural stigma represents an important, but thus far largely underrecognized, mechanism underlying mental health disparities related to sexual orientation among youth. I offer several suggestions to advance research in this area, including (a) adopting a life-course approach to the study of structural stigma; (b) developing novel measures of structural stigma; (c) expanding both the range of methods used for studying structural stigma and the sequelae of structural stigma that are evaluated; (d) identifying potential mediators and moderators of the structural stigma-health relationship; (e) examining intersectionalities; and (f) testing generalizability of structural stigma across other groups, with a particular focus on transgender youth. The implications of this research for preventive interventions and for public policy are also discussed.

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

The theory and the therapeutic procedure of classical psychodrama are described along with brief illustrations. Classical psychodrama and sociodrama stemmed from role theory, enactments, "tele," the reciprocity of choices, and the theory of spontaneity-robopathy and creativity. The discussion focuses on key concepts such as the therapeutic team, the structure of the session, transference and reality, countertransference, the here-and-now and the encounter, the group-as-a-whole, resistance and difficult clients, and affect and cognition. Also described are the neoclassical approaches of psychodrama, action methods, and clinical role playing, and the significance of the concept of behavioral simulation in group psychotherapy.

Bismuth-, Tin-, and Lead-Containing Metal-Organic Materials: Synthesis, Structure, Photoluminescence, Second Harmonic Generation, and Ferroelectric Properties

NASA Astrophysics Data System (ADS)

Wibowo, Arief Cahyo

Metal-Organic Materials (MOMs) contain metal moieties and organic ligands that combine to form discrete (e.g. metal-organic polyhedra, spheres or nanoballs, metal-organic polygons) or polymeric structures with one-, two-, or three-dimensional periodicities that can exhibit a variety of properties resulting from the presence of the metal moieties and/or ligand connectors in the structure. To date, MOMs with a range of functional attributes have been prepared, including record-breaking porosity, catalytic properties, molecular magnetism, chemical separations and sensing ability, luminescence and NLO properties, multiferroic, ferroelectric, and switchable molecular dielectric properties. We are interested in synthesizing non-centrosymmetric MOM single crystals possessing one of the ten polar space groups required for non-linear optical properties (such as second harmonic generation) and ferroelectric applications. This thesis is divided into two main parts: materials with optical properties, such as photoluminescence and materials for targeted applications such as second harmonic generation and ferroelectric properties. This thesis starts with an introduction describing material having centrosymmetric, non-polar space groups, single crystals structures and their photoluminescence properties. These crystals exhibit very interesting and rare structures as well as interesting photoluminescence properties. Chapters 2-5 of this thesis focus on photoluminescent properties of new MOMs, and detail the exploratory research involving the comparatively rare bismuth, lead, and tin coordination polymers. Specifically, the formation of single white-light emitting phosphors based on the combination of bismuth or lead with pyridine-2,5-dicarboxylate is discussed (Chapter 2). The observation of a new Bi2O2 layer and a new Bi4O 3 chain in bismuth terephthalate-based coordination polymers is presented in Chapter 3, while the formation of diverse structures of tin-based coordination polymer ranging from 1D supramolecular structures to true 3D coordination polymers is covered in Chapter 4. The observation of a new 2D Kagome lattice and unique layered perovskite-type bismuth-based coordination polymers and their photoluminescence properties is the focus of Chapter 5. In chapters 6 and 7, a successful approach to implement our novel hybrid strategy for synthesizing enantiomerically pure single crystals consisting of Second Order Jahn Teller (SOJT)-possessing main group metal cations, specifically bismuth and tin, and homochiral ligands or unsymmetric ligands is discussed. The new MOMs with polar space groups exhibit second harmonic generation and have potential for ferroelectric properties.

We investigate the properties of photometrically selected compact groups (CGs) in the Sloan Digital Sky Survey. In this paper, the fourth in a series, we focus on understanding the characteristics of our observed CG sample with particular attention paid to quantifying and removing contamination from projected foreground or background galaxies. Based on a simple comparison of pairwise redshift likelihoods, we find that approximately half of CGs in the parent sample contain one or more projected (interloping) members; our final clean sample contains 4566 galaxies in 1086 CGs. We show that half of the remaining CGs are associated with rich groups (or clusters), i.e. they are embedded sub-structure. The other half have spatial distributions and number-density profiles consistent with the interpretation that they are either independently distributed structures within the field (i.e. they are isolated) or associated with relatively poor structures. Comparisons of late-type and red-sequence fractions in radial annuli show that galaxies around apparently isolated CGs resemble the field population by 300 to 500 kpc from the group centre. In contrast, the galaxy population surrounding embedded CGs appears to remain distinct from the field out beyond 1 to 2 Mpc, consistent with results for rich groups. We take this as additional evidence that the observed distinction between CGs, i.e. isolated versus embedded, is a separation between different host environments.

Chronic back pain is a major public health problem and the primary reason patients seek massage treatment. Despite the growing use of massage for chronic low back pain, there have been few studies of its effectiveness. This trial will be the first evaluation of the effectiveness of relaxation massage for chronic back pain and the first large trial of a focused structural form of massage for this condition. A total of 399 participants (133 in each of three arms) between the ages of 20 and 65 years of age who have low back pain lasting at least 3 months will be recruited from an integrated health care delivery system. They will be randomized to one of two types of massage ("focused structural massage" or "relaxation massage"), or continued usual medical care. Ten massage treatments will be provided over 10 weeks. The primary outcomes, standard measures of dysfunction and bothersomeness of low back pain, will be assessed at baseline and after 10, 26, and 52 weeks by telephone interviewers masked to treatment assignment. General health status, satisfaction with back care, days of back-related disability, perceived stress, and use and costs of healthcare services for back pain will also be measured. Outcomes across assigned treatment groups will be compared using generalized estimating equations, accounting for participant correlation and adjusted for baseline value, age, and sex. For both primary outcome measures, this trial will have at least 85% power to detect the presence of a minimal clinically significant difference among the three treatment groups and 91% power for pairwise comparisons. Secondary analyses will compare the proportions of participants in each group that improve by a clinically meaningful amount. Results of this trial will help clarify the value of two types of massage therapy for chronic low back pain.

In the last decades cancer has become one of the important causes of death in Iran .This study examined perspective of a group of Iranian health professionals, patients and patients' family members regarding their view on disclosure of cancer information at a university hospital in Tehran, Iran. The method of study was qualitative semi-structured focused group content analysis. Two group leaders (psychologist and psychiatrist) run the focus groups. Oncologists, nurses, patients and family members participated in separate focus groups. Five group sessions were held to sum up the participants views in four major topics related to disclosure of cancer information to patients and families. Most of physicians and nurses believed that disclosure of cancer diagnosis is a mistake. Family members think that it should be delivered gradually during stages of therapy based on patient's psychological state, but most of the patients consider truth telling as a patient right. All physicians, most of nurses and all the patients see the physician as a person responsible to break the diagnostic disclosure. All patients wanted the physicians to take the total control of decision-making process for their treatment. Iranian physicians and nurses hesitate to disclose cancer diagnosis compared to patients, who want to know the truth. Patients, nurses and physicians consider the physician to be the person responsible for delivering the information of cancer diagnosis .Development and implementation of a protocol based on Iranian culture is a necessity.

Inpatient medical rehabilitation has maintained a typical medical-model focus and structure for many years. However, as integrative therapies, such as yoga therapy, emerge as treatments which can enhance the physical and mental health of its participants, it is important to determine if they can be easily implemented into the traditional rehabilitation structure and milieu. Therefore, the purpose of this study was to examine the perceptions of key agency personnel on the feasibility and utility of yoga therapy implemented in inpatient rehabilitation. This study reports the results of focus groups and an individual interview with key stakeholders (administrators and rehabilitation therapists) from two rehabilitation hospitals following the implementation of yoga therapy. Results focused on several key themes: feasibility from the therapist and administrator perspectives, challenges to implementation, and utility and benefit. Overall, the implementation and integration of yoga therapy were positive; however, some programmatic and policy and organizational considerations remain. Implications for practice and future research are provided. PMID:26491457

Black women bear a disproportionate burden of HIV/AIDS in North America. The purpose of this investigation was to explore Black Canadian women's perspectives on HIV risk and prevention. Four 90-minute focus groups (n=26) and six key informant interviews were conducted in Toronto with Black women of African and Caribbean descent and low socioeconomic status. Data analysis revealed a number of potent barriers to existing HIV preventive interventions: stigma, cultural disconnections, lack of engagement of Black religious institutions, and multiple intersecting forms of discrimination. Recommended HIV prevention opportunities included the Black church, mainstreaming, health care providers, and ethno-specific agencies. HIV prevention strategies for North American Black women, rather than focusing on HIV and individual risk behaviors, may benefit from a primary focus on social and structural factors (e.g., promoting gender equality, economic opportunity, women-controlled prevention technologies and combating racism in health care) thereby integrating HIV prevention into the larger context of community health and survival.

Physical activity and beverage consumption in preschoolers: focus groups with parents and teachers

2013-01-01

Background Qualitative research is a method in which new ideas and strategies can be discovered. This qualitative study aimed to investigate parents’ and teachers’ opinions on physical activity and beverage consumption of preschool children. Through separate, independent focus groups, they expressed their perceptions on children’s current physical activity and beverage consumption levels, factors that influence and enhance these behaviours, and anticipated barriers to making changes. Methods Multi-cultural and multi-geographical focus groups were carried out in six European countries (Belgium, Bulgaria, Germany, Greece, Poland and Spain). In total, twenty-four focus groups with 122 parents and eighteen focus groups with 87 teachers were conducted between October 2010 and January 2011. Based on a semi-structured interview guide, questions on preschoolers’ physical activity (opinions on preschoolers’ physical activity, how to increase physical activity, facilitators and barriers of physical activity) and beverage consumption (rules and policies, factors influencing promotion of healthy drinking, recommendations for future intervention development) were asked. The information was analyzed using qualitative data analysis software (NVivo8). Results The focus group results indicated misperceptions of caregivers on preschoolers’ physical activity and beverage consumption levels. Caregivers perceived preschoolers as sufficiently active; they argue that children need to learn to sit still in preparation for primary school. At most preschools, children can drink only water. In some preschools sugar-sweetened beverages like chocolate milk or fruit juices, are also allowed. It was mentioned that sugar-sweetened beverages can be healthy due to mineral and vitamin content, although according to parents their daily intake is limited. These opinions resulted in low perceived needs to change behaviours. Conclusions Although previous research shows need of change in obesity-related behaviours, the participants in the current study didn’t perceive such. The awareness of parents and teachers needs to be raised concerning their shared responsibility about healthy behaviours in preschoolers. Providing preschool teachers with ready-to-use classroom material will encourage them to change physical activity and beverage consumption, and to implement related activities in the classroom. Involvement in activities that their children perform at preschool will motivate parents to extend these behaviours to the home environment. PMID:23537117

Layered group-IV monochalcogenides have become an important group of materials within the ever-growing family of two-dimensional crystals. Among the binary IV-VI compounds, SnS, SnSe, GeS, and GeSe form a subgroup with orthorhombic structure which has shown exciting particularities and has been considered of high potential for numerous application. We give a brief overview of some important properties of the 2D form of this group and focus on recent results addressing the excitonic properties and the impact of the introduction of point defects on their structures. Vacancies and oxygen defects are modeled using first principles calculations. Energetic and structural analysis of five different models for chemisorbed oxygen atoms, reveals a better resistance of these materials to oxidation if compared to their isostructural partner, phosphorene. We also discuss a parallel work where quasi-particle band structure and excitonic properties of GeS and GeSe monolayers are investigated through ab initio GW and Bethe-Salpeter equation calculations. Within the main results, we show that the optical spectra of both materials are dominated by excitonic effects, however, GeS presents a remarkably larger binding energy of 1 eV.

Focus group interviews have been used extensively in health services program planning, health education, and curriculum planning. However, with the exception of a few reports describing the use of focus groups for a basic science course evaluation and a clerkship's impact on medical students, the potential of focus groups as a tool for curriculum evaluation has not been explored. Focus groups are a valid stand-alone evaluation process, but they are most often used in combination with other quantitative and qualitative methods. Focus groups rely heavily on group interaction, combining elements of individual interviews and participant observation. This article compares the focus group interview with both quantitative and qualitative methods; discusses when to use focus group interviews; outlines a protocol for conducting focus groups, including a comparison of various styles of qualitative data analysis; and offers a case study, in which focus groups evaluated the effectiveness of a pilot preclinical curriculum.

Data collection focused on how sending-country violence and structural violence in a new environment affect immigrant health vulnerability and risk behaviors. A qualitative approach included ethnographic observation, media content analysis, focus groups, and individual interviews with refugees (N = 137). The focus groups (5) provided perspectives on the research domains by sex workers; drug users; male and female refugees; and service providers. Social and economic marginalization are impacting the health and well being of this growing refugee population. Data illustrate how stigma and discrimination affect food and housing security, employment and health services, and shape vulnerabilities and health risks in a new receiving environment. Widespread discrimination in Ecuador reflects fears, misunderstanding, and stereotypes about Colombian refugees. For this displaced population, the sequelae of violence, combined with survival needs and lack of support and protections, shape new risks to health and well-being.

As part of a breastfeeding promotion intervention trial in Nigeria, we provided one cell phone per group of 5-7 microcredit clients and instructed the group's cell phone recipient to share weekly breastfeeding voice and text messages with group members. We measured the feasibility and acceptability of using group cell phones by conducting semi-structured exit interviews with 195 microcredit clients whose babies were born during the intervention (target group), in-depth interviews with eight phone recipients and nine non-phone recipients, and 16 focus group discussions with other microcredit clients. Women in the target group said the group phone worked well or very well (64%). They were motivated to try the recommended practices because they trusted the information (58%) and had support from others (35%). Approximately 44% of target women reported that their groups met and shared messages at least once a week. Women in groups that met at least weekly had higher odds of exclusive breastfeeding up to 6 months (OR 5.6, 95% CI 1.6, 19.7) than women in groups that never met. In-depth interviews and focus group discussions indicated that non-phone recipients had positive feelings towards phone recipients, the group phone met participants' needs, and messages were often shared outside the group. In conclusion, group cell phone messaging to promote breastfeeding among microcredit clients is feasible and acceptable and can be part of an effective behaviour change package. © 2016 John Wiley & Sons Ltd.

To explore the attributes of the therapy encounter valued by repeat users of health-related massage therapy. A qualitative design with telephone focus group methodology was used. A total of 19 repeat users of massage therapy participated in three telephone focus groups where audiotaped semi-structured interviews were conducted. Telephone focus group with massage clients from a range of provincial and urban regions in New Zealand. Summary of reported themes of the massage experience. Data were thematically analysed using the general inductive approach. Six valued elements of the massage encounter (time for care and personal attention, engaging and competent therapist, trust partnership, holism and empowerment, effective touch and enhancing relaxation), four modulators (comfort, contact, connection and caring) and two themes relating to adding experiential value (enjoyment, escapism) characterize the massage therapy culture. The culture of massage therapy care incorporates a number of characteristics that are congruent with the complementary and alternative medicine approach to health. In addition, massage specific factors were identified. The humanistic aspects of the therapy encounter valued by clients offer insight into the growing use of massage therapy and the success of massage therapy outcomes.

UK national guidance has prioritized developing specialist services for first episode psychosis. Such services are in the early stages of development and a definitive treatment model has yet to be established. The aim of this study was to explore service users' experiences of a first episode intervention designed along evidence-based 'best practice' guidelines and to establish specific elements seen as effective to help inform future service planning and provision. Twelve users of a specialist first episode service participated in focus groups. These were then analyzed using Interpretative Phenomenological Analysis, a specialized form of content analysis. Key elements identified by the service users included the 'human' approach as a key to the recovery process, being involved in treatment decisions, flexibility of appointments, high nurse to patient ratio, reduction in psychotic symptoms, increased confidence and independence and the provision of daily structure. To our knowledge, this is the first systematic qualitative evaluation of users' experience of a specialist first episode treatment intervention. Our findings indicate that adherence to best practice guidelines was appreciated. Regular focus groups provide a continuous audit cycle incorporating service improvements in line with government recommendations, centrally informed by the service users' and caregivers' perspective.

This focus group study was undertaken as part of a larger investigation of how the demand for increased production of nurses with doctorates affects doctoral faculty's scholarly productivity. This study provided a basis for development of the national survey questionnaire. Two focus groups that included 29 faculty teaching in doctor of philosophy and/or doctor of nursing practice programs took place at one of two national conferences. The focus group interviews were transcribed and content analyzed for the identification of themes; all members of the research team reached consensus. The three major themes were the demands of teaching, the importance of institutional structure and climate, and the sustainability of one's self, the institution, and the discipline. Participants identified strategies for enhancing scholarly productivity. Findings are limited by the small sample size and the voluntary participation of conference attendees. The strength of emotion that participants revealed underscores the need for nursing leaders to address the increasing academic expectations for faculty. If the profession does not address the needs of its current and future faculty, goals explicated by the Institute of Medicine in The Future of Nursing cannot be achieved, and the health of the nation will suffer.

To describe and define the experiences of adults with cerebral palsy (CP) and parents of adults with CP who have been involved in a transfer of physiatry care from pediatric to adult healthcare and to explore their experiences more generally in the transition from pediatric to adult services. A qualitative research approach was used. Semi-structured focus group interviews were conducted with adults with CP (n=5) and parents of adults with CP (n=8) to explore the health care transition (HCT) process from pediatric to adult healthcare. Four key content domains were used to facilitate the focus groups; 1) Transition Planning, 2) Accessibility of Services, 3) Experience with Adult Providers, and 4) Recommendations for Improving the Transition Process. Conventional content analysis was used to analyze the data. Four themes emerged from the focus groups; Lost in Transition, Roadmap to Care, List of None, and One Stop Shopping. Participants felt lost in the HCT process, requested a transparent transition plan, expressed concern regarding access to adult healthcare, and made recommendations for improvements. Challenges in transitioning from pediatric to adult health care were identified by all participants and several strategies were recommended for improvement.

To present voices of young women who were pregnant or new parents as they shared their thoughts on the risks, behaviors, and prevention of teen dating violence (TDV). Descriptive, qualitative analysis. Focus groups in schools designed expressly for the needs of young women who are pregnant and parenting. Twenty-six young mothers participated in one of three focus groups. Focus groups explored perceptions of several dimensions of intimate partner violence within the context of pregnancy and parenting. A semi-structured interview guide provided the medium to delve into young mothers' thoughts and perspectives about TDV. Data were organized in four major typologies: describing TDV, increasing the risk, why violence, and prevention of TDV. This analysis provides important insights into young mothers' lives when teen parenting and violence intersect. Rich data provide the foundation to expand awareness and inform programs and policies designed to address TDV in young women who are pregnant and parenting. Findings may be used by nurses to assess risk, identify teens in violent relationships, and provide for understanding of TDV from the perspectives of young women who are pregnant and parenting. © 2013 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

As Type 2 diabetes spikes among minority and low-income youth, there is an urgent need to tackle the drivers of this preventable disease. The Bigger Picture (TBP) is a counter-marketing campaign using youth-created, spoken-word public service announcements (PSAs) to reframe the epidemic as a socio-environmental phenomenon requiring communal action, civic engagement and norm change. Methods: We examined whether and how TBP PSAs advance health literacy among low-income, minority youth. We showed nine PSAs, asking individuals open-ended questions via questionnaire, then facilitating a focus group to reflect upon the PSAs. Results: Questionnaire responses revealed a balance between individual vs. public health literacy. Some focused on individual responsibility and behaviors, while others described socio-environmental forces underlying risk. The focus group generated a preponderance of public health literacy responses, emphasizing future action. Striking sociopolitical themes emerged, reflecting tensions minority and low-income youth experience, such as entrapment vs. liberation. Conclusion: Our findings speak to the structural barriers and complexities underlying diabetes risk, and the ability of spoken word medium to make these challenges visible and motivate action. Practice Implications: Delivering TBP content to promote interactive reflection has potential to change behavioral norms and build capacity to confront the social, economic and structural factors that influence behaviors.

Background Buprenorphine maintenance treatment is effective and has been successfully integrated into HIV and primary care settings. However, one key barrier to providers prescribing buprenorphine is their perception that they are unable to provide adequate counseling or psychosocial support to patients with opioid addiction. This qualitative study investigated supportive elements of office-based buprenorphine treatment that patients perceived to be most valuable. Methods We conducted five focus groups with 33 buprenorphine treatment-experienced participants. Focus groups were audio-recorded and transcribed. Iterative readings of transcripts and grounded theory analysis revealed common themes. Results Overall, participants perceived that buprenorphine treatment helped them to achieve their treatment goals and valued the flexibility, accessibility, and privacy of treatment. Participants identified interpersonal and structural elements of buprenorphine treatment that provided psychosocial support. Participants desired good physician-patient relationships, but also valued care delivery models that were patient-centered, created a safe place for self-disclosure, and utilized coordinated team-based care. Conclusions Participants derived psychosocial support from their prescribing physician, but were also open to collaborative or team-based models of care, as long as they were voluntary and confidential. Buprenorphine prescribing physicians without access to referral options for psychosocial counseling could focus on maintaining non-judgmental attitudes and shared decision making during patient encounters. Adding structure and psychosocial support to buprenorphine treatment through coordinated team-based care also seems to have great promise. PMID:26566712

A documented gap in support exists for service users following discharge from acute mental health services, and structured interventions to reduce relapse are rarely provided. Peer-facilitated self-management interventions have potential to meet this need, but evidence for their effectiveness is limited. This paper describes the development of a peer-provided self-management intervention for mental health service users following discharge from crisis resolution teams (CRTs). A five-stage iterative mixed-methods approach of sequential data collection and intervention development was adopted, following the development and piloting stages of the MRC framework for developing and evaluating complex interventions. Evidence review (stage 1) included systematic reviews of both peer support and self-management literature. Interviews with CRT service users (n = 41) regarding needs and priorities for support following CRT discharge were conducted (stage 2). Focus group consultations (n = 12) were held with CRT service-users, staff and carers to assess the acceptability and feasibility of a proposed intervention, and to refine intervention organisation and content (stage 3). Qualitative evaluation of a refined, peer-provided, self-management intervention involved qualitative interviews with CRT service user participants (n = 9; n = 18) in feasibility testing (stage 4) and a pilot trial (stage 5), and a focus group at each stage with the peer worker providers (n = 4). Existing evidence suggests self-management interventions can reduce relapse and improve recovery. Initial interviews and focus groups indicated support for the overall purpose and planned content of a recovery-focused self-management intervention for people leaving CRT care adapted from an existing resource: The personal recovery plan (developed by Repper and Perkins), and for peer support workers (PSWs) as providers. Participant feedback after feasibility testing was positive regarding facilitation of the intervention by PSWs; however, the structured self-management booklet was underutilised. Modifications to the self-management intervention manual and PSWs' training were made before piloting, which confirmed the acceptability and feasibility of the intervention for testing in a future, definitive trial. A manualised intervention and operating procedures, focusing on the needs and priorities of the target client group, have been developed through iterative stages of intervention development and feedback for testing in a trial context.

Flagella/cilia are motile organelles with more than 400 proteins. To understand the mechanism of such complex systems, we need methods to describe molecular arrange-ments and conformations three-dimensionally in vivo. Cryo-electron tomography enabled us such a 3D structural analysis. Our group has been working on 3D structure of flagella/cilia using this method and revealed highly ordered and beautifully organized molecular arrangement. 3D structure gave us insights into the mechanism to gener-ate bending motion with well defined waveforms. In this review, I summarize our recent structural studies on fla-gella/cilia by cryo-electron tomography, mainly focusing on dynein microtubule-based ATPase motor proteins and the radial spoke, a regulatory protein complex.

Rhodopsin is a retinal photoreceptor protein of bipartite structure consisting of the transmembrane protein opsin and a light-sensitive chromophore 11-cis-retinal, linked to opsin via a protonated Schiff base. Studies on rhodopsin have unveiled many structural and functional features that are common to a large and pharmacologically important group of proteins from the G protein-coupled receptor (GPCR) superfamily, of which rhodopsin is the best-studied member. In this work, we focus on structural features of rhodopsin as revealed by many biochemical and structural investigations. In particular, the high-resolution structure of bovine rhodopsin provides a template for understanding how GPCRs work. We describe the sensitivity and complexity of rhodopsin that lead to its important role in vision. PMID:12471166

We have performed a crystal structure prediction study of CaMnO3 focusing on structures generated by octahedral tilting according to group-subgroup relations from the ideal perovskite type (Pm\\overline 3 m), which is the aristotype of the experimentally known CaMnO3 compound in the Pnma space group. Furthermore, additional structure candidates have been obtained using data mining. For each of the structure candidates, a local optimization on the ab initio level using density-functional theory (LDA, hybrid B3LYP) and the Hartree--Fock (HF) method was performed, and we find that several of the modifications may be experimentally accessible. In the high-pressure regime, we identify a post-perovskite phase in the CaIrO3 type, not previously observed in CaMnO3. Similarly, calculations at effective negative pressure predict a phase transition from the orthorhombic perovskite to an ilmenite-type (FeTiO3) modification of CaMnO3.

Since the enactment of the Affordable Care Act (ACA), the rate of uninsured in the United States has declined significantly. However, not all legal residents have benefited equally. As part of a community-based participatory research (CBPR) partnership with the Marshallese community, an interpretative policy analysis research project was conducted to document Marshallese Compact of Free Association (COFA) migrants' understanding and experiences regarding the ACA and related health policies. This article is structured to allow the voice of Marshallese COFA migrants to explain their understanding and interpretation of the ACA and related polices on their health in their own words. Qualitative data was collected from 48 participants in five focus groups conducted at the local community center and three individual interviews for those unable to attend the focus groups. Marshallese community co-investigators participated throughout the research and writing process to ensure that cultural context and nuances in meaning were accurately captured and presented. Community co-investigators assisted with the development of the semi-structured interview guide, facilitated focus groups, and participated in qualitative data analysis. Content analysis revealed six consistent themes across all focus groups and individual interviews that include: understanding, experiences, effect on health, relational/historical lenses, economic contribution, and pleas. Working with Marshallese community co-investigators, we selected quotations that most represented the participants' collective experiences. The Marshallese view the ACA and their lack of coverage as part of the broader relationship between the Republic of the Marshall Islands (RMI) and the United States. The Marshallese state that they have honored the COFA relationship, and they believe the United States is failing to meet its obligations of care and support outlined in the COFA. While the ACA and Medicaid Expansion have reduced the national uninsured rate, Marshallese COFA migrants have not benefited equally from this policy. The lack of healthcare coverage for the Marshallese COFA migrants exacerbates the health disparities this underserved population faces. This article is an important contribution to researchers because it presents the Marshallese's interpretation of the policy, which will help inform policy makers that are working to improve Marshallese COFA migrant health.

Las experiencias clinicas de los estudiantes de enfermeria: Estudio de caso hacia la integracion de la mentoria

Rivera Rodriguez, Ivelisse

Clinical experiences are an essential part of the training of future nursing professionals. The period of clinical experience aims to develop in the student the necessary skills to practice as a nursing professional, when the academic program ends. This case study aimed to understand the opinion and explore the perception of faculty, clinical instructors, and nursing students on the meaning, contributions and challenges presented during clinical experiences. Among the themes explored in the focus groups were the meaning and importance to learning about the profession of clinical experiences, teaching strategies used during the practice scenarios, didactic relationships developed among students, clinical instructors, and teachers. The goal was to learn from all participants about what they do, their expectations, and the challenges presented during the clinical experiences. A qualitative, descriptive and contextual research design was followed, which required conducting six focus groups to collect the information from the perspective of all the participants. Faculty, clinical instructors, and nursing students participated each in two focus groups. Collected data were transcribed, coded and analyzed in order to organize it under themes related to the research framework. The qualitative analysis of the focus groups revealed that nursing faculty and clinical instructors perceived clinical experiences as a very important element in the training of nursing students, but that coordination between the academy and practice scenarios is disconnected and needs improvement. They also expressed that they use various learning strategies during the clinical experiences, however, they recognize it needs more structure and suggested mentoring as a strategy to consider. They affirmed that mentoring could contribute positively to enhance the teaching-learning process. Clinical instructors understand they perform mentoring roles, but they would like to have a more defined role and structured process. Nursing students, also, recognized the importance of clinical experiences in their professional training. They expressed the need to improve the communication between the academy and the practice scenarios in order to reduce the levels of anxiety they experience when entering the clinical experiences. Nursing students also expressed the need to consider the use of different teaching strategies, such as mentoring, to improve clinical experiences.

The misuse and abuse of Enduring Powers of Attorney (EPAs) by attorneys, particularly in relation to financial decision-making, is a growing concern. This paper explores the opportunities to enhance accountability of attorneys at the time of the execution of the document in Queensland. A four-stage multi-method design comprised a critical reference group; semi-structured interviews with 32 principals or potential principals, attorneys and witnesses; two focus groups with service providers and a state-wide survey of 76 principals, attorneys and witnesses. Across all methods and user groups, understanding the role and obligations of the attorney in an EPA was consistently identified as problematic. Promoting accountability and understanding can be addressed by greater attention to the role of the attorney in the forms/ guidelines and in the structure and witnessing of the forms, increased direction about record keeping and access to appropriate advice and support. © 2013 ACOTA.

That the speed of light in free space is constant is a cornerstone of modern physics. However, light beams have finite transverse size, which leads to a modification of their wave vectors resulting in a change to their phase and group velocities. We study the group velocity of single photons by measuring a change in their arrival time that results from changing the beam's transverse spatial structure. Using time-correlated photon pairs, we show a reduction in the group velocity of photons in both a Bessel beam and photons in a focused Gaussian beam. In both cases, the delay is several micrometers over a propagation distance of ~1 meter. Our work highlights that, even in free space, the invariance of the speed of light only applies to plane waves. Copyright © 2015, American Association for the Advancement of Science.

Contexts, Mechanisms, and Outcomes That Matter in Dutch Community-Based Physical Activity Programs Targeting Socially Vulnerable Groups.

2017-09-01

This article presents a practitioner-based approach to identify key combinations of contextual factors (C) and mechanisms (M) that trigger outcomes (O) in Dutch community-based health-enhancing physical activity (CBHEPA) programs targeting socially vulnerable groups. Data were collected in six programs using semi-structured interviews and focus groups using a timeline technique. Sessions were recorded, anonymized, and transcribed. A realist synthesis protocol was used for data-driven and thematic analysis of CMO configurations. CMO configurations related to community outreach, program sustainability, intersectoral collaboration, and enhancing participants' active lifestyles. We have refined the CBHEPA program theory by showing that actors' passion for, and past experiences with, physical activity programs trigger outcomes, alongside their commitment to socially vulnerable target groups. Project discontinuity, limited access to resources, and a trainer's stand-alone position were negative configurations. The authors conclude that local governance structures appear often to lack adaptive capacity to accommodate multilevel processes to sustain programs.

The cultural evolution of emergent group-level traits.

PubMed

Smaldino, Paul E

2014-06-01

Many of the most important properties of human groups - including properties that may give one group an evolutionary advantage over another - are properly defined only at the level of group organization. Yet at present, most work on the evolution of culture has focused solely on the transmission of individual-level traits. I propose a conceptual extension of the theory of cultural evolution, particularly related to the evolutionary competition between cultural groups. The key concept in this extension is the emergent group-level trait. This type of trait is characterized by the structured organization of differentiated individuals and constitutes a unit of selection that is qualitatively different from selection on groups as defined by traditional multilevel selection (MLS) theory. As a corollary, I argue that the traditional focus on cooperation as the defining feature of human societies has missed an essential feature of cooperative groups. Traditional models of cooperation assume that interacting with one cooperator is equivalent to interacting with any other. However, human groups involve differential roles, meaning that receiving aid from one individual is often preferred to receiving aid from another. In this target article, I discuss the emergence and evolution of group-level traits and the implications for the theory of cultural evolution, including ramifications for the evolution of human cooperation, technology, and cultural institutions, and for the equivalency of multilevel selection and inclusive fitness approaches.

Although previous investigations of transsexual people have focused on regional brain alterations, evaluations on a network level, especially those structural in nature, are largely missing. Therefore, we investigated the structural connectome of 23 female-to-male (FtM) and 21 male-to-female (MtF) transgender patients before hormone therapy as compared with 25 female and 25 male healthy controls. Graph theoretical analysis of whole-brain probabilistic tractography networks (adjusted for differences in intracranial volume) showed decreased hemispheric connectivity ratios of subcortical/limbic areas for both transgender groups. Subsequent analysis revealed that this finding was driven by increased interhemispheric lobar connectivity weights (LCWs) in MtF transsexuals and decreased intrahemispheric LCWs in FtM patients. This was further reflected on a regional level, where the MtF group showed mostly increased local efficiencies and FtM patients decreased values. Importantly, these parameters separated each patient group from the remaining subjects for the majority of significant findings. This work complements previously established regional alterations with important findings of structural connectivity. Specifically, our data suggest that network parameters may reflect unique characteristics of transgender patients, whereas local physiological aspects have been shown to represent the transition from the biological sex to the actual gender identity.

Stigma and discrimination harm the wellbeing of lesbian, gay, bisexual and transgender (LGBT) people and contribute to migration from contexts of sexual persecution and criminalization. Yet LGBT newcomers and refugees often face marginalization and struggles meeting the social determinants of health (SDOH) following immigration to countries such as Canada. Social isolation is a key social determinant of health that may play a significant role in shaping health disparities among LGBT newcomers and refugees. Social support may moderate the effect of stressors on mental health, reduce social isolation, and build social networks. Scant research, however, has examined social support groups targeting LGBT newcomers and refugees. The purpose of this qualitative study was to explore experiences of social support group participation among LGBT African and Caribbean newcomers and refugees in an urban Canadian city. We conducted 3 focus groups with a venue-based sample of LGBT African and Caribbean newcomers and refugees (n = 29) who attended social support groups at an ethno-specific AIDS Service Organization. Focus groups followed a semi-structured interview guide and were analyzed using narrative thematic techniques. Participant narratives highlighted immigration stressors, social isolation, mental health issues, and challenges meeting the SDOH. Findings reveal multi-level benefits of social support group participation at intrapersonal (self-acceptance, improved mental health), interpersonal (reduced isolation, friendships), community (reciprocity, reduced stigma and discrimination), and structural (housing, employment, immigration, health care) levels. Findings suggest that social support groups tailored for LGBT African and Caribbean newcomers and refugees can address social isolation, community resilience, and enhance resource access. Health care providers can provide support groups, culturally and LGBT competent health services, and resource access to promote LGBT newcomers and refugees' health and wellbeing.

Objective To elicit the explanatory models (EM) of hypertension among patients in a hospital-based primary care practice in Nigeria. Design Semi-structured in-depth individual interviews and focus groups were conducted with 62 hypertensive patients. Interviews and focus groups were audio-taped and transcribed verbatim. Data analysis was guided by phenomenology and content analysis using qualitative research software ATLAS.ti 5.0. Results Patients expressed four categories of EM of hypertension: 1) perceptions of hypertension, 2) consequences, 3) effect on daily life, and 4) perception of treatment. Focus group discussions and key informant interviews yielded a wide range of insights into the social and cultural factors influencing patients’ beliefs and health behavior. Participants were aware of the risks of hypertension. There was disagreement between participants’ own understanding of the serious nature of hypertension, the need for long-term treatment, and the desire to take medication long-term. Participants acknowledged the use of traditional medicine (e.g. teas and herbs) and healers. Different themes emerged for men versus women such that women often focused on family issues while men tended to discuss external stressors stemming from work as a cause of hypertension. Men were concerned with frequent urination, decreased libido and erectile dysfunction. Conclusion Knowledge gained will inform development of patient-centered treatment plans and targeted behavioral and educational interventions. PMID:23534506

Recruitment of low- and middle-income country volunteers from most-at-risk populations in HIV vaccine trials is essential to vaccine development. In India, men who have sex with men (MSM) are at disproportionately high risk for HIV infection and an important population for trial recruitment. Investigations of willingness to participate (WTP) in HIV vaccine trials have focused predominantly on individual-level determinants. We explored multi-level factors associated with WTP among MSM in India. We conducted 12 focus groups (n = 68) with low socioeconomic MSM in Chennai and Mumbai, and 14 key informant interviews with MSM community leaders and service providers. Focus groups/interviews were recorded, transcribed and translated into English. Two bilingual investigators conducted thematic analysis using line-by-line coding and a constant comparative method, with member-checking by community representatives. Factors associated with WTP were evidenced across the social ecology of MSM-social-structural: poverty, HIV-, sexual- and gender non-conformity stigma, institutionalized discrimination and government sponsorship of trials; community-level: endorsement by MSM community leaders and organizations, and fear of within-group discrimination; interpersonal: anticipated family discord, partner rejection, having financially-dependent family members and disclosure of same-sex sexuality; and individual-level: HIV vaccine trial knowledge and misconceptions, safety concerns, altruism and preventive misconception. Pervasive familial, community and social-structural factors characteristic of the Indian sociocultural context may complicate individual-focused approaches to WTP and thereby constrain the effectiveness of interventions to support recruitment and retention in HIV vaccine trials. Interventions to reduce stigma and discrimination against MSM and people living with HIV, capacity-building of MSM community organizations and transparent communications tailored to the knowledge and educational level of local communities may support meaningful engagement of MSM in HIV vaccine trials. Vigilance in providing fair but not excessive compensation and healthcare benefits and in mitigating preventive misconception are warranted to support ethical conduct of trials among MSM in India.

The aim of this study was to explore the perceptions of health care among persons living with inflammatory bowel disease. The quality of care plays an important role in the life of persons with a chronic disease. To define what persons with inflammatory bowel disease perceive as high-quality care, greater focus must be placed on the individual's own perspective of living with the condition. A qualitative exploratory study was conducted based on focus groups. Five focus groups were conducted with adult persons living with inflammatory bowel disease, 14 men and 12 women aged 19-76 years. The interviews were performed between January-June 2014. The perceptions of health care from the perspective of persons living with inflammatory bowel disease were summarised in two categories: 'professional attitudes of healthcare staff' and 'structure of the healthcare organisation'. Persons with inflammatory bowel disease want to be encountered with respect, experience trust and obtain information at the right time. They also expect shared decision-making, communication and to encounter competent healthcare professionals. Furthermore, the expectations on and perceptions of the structure of the healthcare organisation comprise access to care, accommodation, continuity of care, as well as the pros and cons of specialised care. The findings show the importance of establishing a respectful and trusting relationship, facilitating healthcare staff and persons with inflammatory bowel disease to work as a team in fulfilling individual care needs - but there is room for improvement in terms of quality of care. A person-centred approach, which places the individual and her/his family at the centre, considering them experts on their own health and enabling them to collaborate with healthcare staff, seems important to reach a high-quality healthcare organisation for patients with Inflammatory bowel disease. © 2017 The Authors.

2013-05-01

This systematic review aimed to establish the current knowledge about brain structure and executive function (EF) in children with cerebral palsy (CP). Five databases were searched (up till July 2012). Six articles met the inclusion criteria, all included structural brain imaging though no functional brain imaging. Study quality was assessed using the STROBE checklist. All articles scored between 58.7% and 70.5% for quality (100% is the maximum score). The included studies all reported poorer performance on EF tasks for children with CP compared to children without CP. For the selected EF measures non-significant effect sizes were found for the CP group compared to a semi-control group (children without cognitive deficits but not included in a control group). This could be due to the small sample sizes, group heterogeneity and lack of comparison of the CP group to typically developing children. The included studies did not consider specific brain areas associated with EF performance. To conclude, there is a paucity of brain imaging studies focused on EF in children with CP, especially of studies that include functional brain imaging. Outcomes of the present studies are difficult to compare as each study included different EF measures and cortical abnormality measures. Copyright © 2013 Elsevier Ltd. All rights reserved.

Active ingredients of substance use-focused self-help groups.

PubMed

Moos, Rudolf H

2008-03-01

This paper provides an overview of some of the probable active ingredients of self-help groups in light of four related theories that identify common social processes that appear to underlie effective psychosocial treatments for and continuing remission from these disorders. Social control theory specifies active ingredients such as bonding, goal direction and structure; social learning theory specifies the importance of norms and role models, behavioral economics and behavioral choice theory emphasizes involvement in rewarding activities other than substance use, and stress and coping theory highlights building self-efficacy and effective coping skills. A review of existing studies suggests that the emphasis on these active ingredients probably underlies some aspects of the effectiveness of self-help groups. Several issues that need to be addressed to enhance understanding of the active ingredients of action of self-help groups are discussed, including consideration of indices of Alcoholics Anonymous (AA) affiliation as active ingredients, identification of personal characteristics that may moderate the influence of active ingredients on substance use outcomes, examination of whether active ingredients of self-help groups, can amplify or compensate for treatment, identification of potential detrimental effects of involvement in self-help groups and focusing on the link between active ingredients of self-help groups and other aspects of the overall recovery milieu, such as the family and social networks.

Supporting positive mental health development in adolescents is a major public health concern worldwide. Although several school-based programs aimed at preventing depression have been launched, it is crucial to evaluate these programs and to obtain feedback from participating adolescents. This study aimed to explore adolescents' experiences with a -based cognitive-behavioral depression prevention program. Eighty-nine adolescents aged 13-15 years were divided into 12 focus groups. The focus group interviews were analyzed using qualitative content analysis. Three categories and eight subcategories were found to be related to the experience of the school-based program. The first category, intrapersonal strategies, consisted of the subcategories of directed thinking, improved self-confidence, stress management, and positive activities. The second category, interpersonal awareness, consisted of the subcategories of trusting the group and considering others. The third category, structural constraints, consisted of the subcategories of negative framing and emphasis on performance. The school-based mental health program was perceived as beneficial and meaningful on both individual and group levels, but students expressed a desire for a more health-promoting approach.

Long-term care institutions have become an option for older people who are dependent in daily living. However, insufficient attention has been focused on assessing the life satisfaction of those currently residing in these institutions in Taiwan. Previous research indicates that group reminiscence may improve the life satisfaction of older adults. However, there is currently no consensus regarding the implementation and evaluation of reminiscence interventions. To examine the effect of a structured group reminiscence protocol on the life satisfaction of institutionalized older adults. The study used a quasi-experimental design. A total of 48 older adults were conveniently recruited from two long-term care institutions in southern Taiwan. The experimental group (n = 23) received 8 weeks of structured-group reminiscence for 40 minutes weekly, while the control group (n = 25) received routine care from the institution. Both groups were evaluated using a life-satisfaction questionnaire before and after the intervention and again four weeks later. Life satisfaction scores were statistically similar on the pre-test and significantly different on both post-test questionnaires for the two groups. The scores for the experimental and control groups were pre-test: 24.22 vs 23.36 (p = .063); post-test I: 27.22 vs 23.32 (p < .001); and post-test II: 26.43 vs 23.00 (p < .001). The mean post-test scores for the experimental group were significantly higher than the pre-test score (p < .001). The generalized estimating equation test showed that the overall score of life satisfaction for the experimental group increased by 0.85-points (p = .042) more than the control group, which is a significant difference. The results support that the 8-week structured group reminiscence protocol effectively enhances life satisfaction in older adults. The results of this study may be referenced in the continuing education of nurses working in long-term care institutions in the context of helping nurses organize, facilitate, and evaluate this protocol.

Population outbreaks of the corallivorous crown-of-thorns seastar (COTS), Acanthaster 'planci' L., are among the most important biological disturbances of tropical coral reefs. Over the past 50 years, several devastating outbreaks have been documented around Guam, an island in the western Pacific Ocean. Previous analyses have shown that in the Pacific Ocean, COTS larval dispersal may be geographically restricted to certain regions. Here, we assess the genetic structure of Pacific COTS populations and compared samples from around Guam with a number of distant localities in the Pacific Ocean, and focused on determining the degree of genetic structure among populations previously considered to be isolated. Using microsatellites, we document substantial genetic structure between 14 localities from different geographical regions in the Pacific Ocean. Populations from the 14 locations sampled were found to be structured in three significantly differentiated groups: (1) all locations immediately around Guam, as well as Kingman Reef and Swains Island; (2) Japan, Philippines, GBR and Vanuatu; and (3) Johnston Atoll, which was significantly different from all other localities. The lack of genetic differentiation between Guam and extremely distant populations from Kingman Reef and Swains Island suggests potential long-distance dispersal of COTS in the Pacific.

Understanding childhood asthma in focus groups: perspectives from mothers of different ethnic backgrounds

Cane, Rachel; Pao, Caroline; McKenzie, Sheila

2001-01-01

Background Diagnosing childhood asthma is dependent upon parental symptom reporting but there are problems in the use of words and terms. The purpose of this study was to describe and compare understandings of childhood 'asthma' by mothers from three different ethnic backgrounds who have no personal experience of diagnosing asthma. A better understanding of parents' perceptions of an illness by clinicians should improve communication and management of the illness. Method Sixty-six mothers living in east London describing their ethnic backgrounds as Bangladeshi, white English and black Caribbean were recruited to 9 focus groups. Discussion was semi-structured. Three sessions were conducted with each ethnic group. Mothers were shown a video clip of a boy with audible wheeze and cough and then addressed 6 questions. Sessions were recorded and transcribed verbatim. Responses were compared within and between ethnic groups. Results Each session, and ethnic group overall, developed a particular orientation to the discussion. Some mothers described the problem using single signs, while others imitated the sound or made comparisons to other illnesses. Hereditary factors were recognised by some, although all groups were concerned with environmental triggers. Responses about what to do included 'normal illness' strategies, use of health services and calls for complementary treatment. All groups were concerned about using medication every day. Expectations about the quality of life were varied, with recognition that restrictions may be based on parental beliefs about asthma, rather than asthma itself. Conclusion Information from these focus groups suggests mothers know a great deal about childhood asthma even though they have no personal experience of it. Knowledge of how mothers from these ethnic backgrounds perceive asthma may facilitate doctor – patient communication with parents of children experiencing breathing difficulties. PMID:11667951

To evaluate the long-term effects of a lifestyle intervention and a structured exercise intervention on physical fitness and cardiovascular risk factors in older adults. Controlled trial with randomization between the intervention groups. Belgium, Vlaams-Brabant. One hundred eighty-six sedentary but healthy men and women aged 60 to 83. Participants in the lifestyle intervention were stimulated to integrate physical activity into their daily routines and received an individualized home-based program supported by telephone calls. The structured intervention consisted of three weekly supervised sessions in a fitness center. Both interventions lasted 11 months and focused on endurance, strength, flexibility, and postural and balance exercises. Cardiorespiratory fitness, muscular strength, functional performance, blood pressure, and body composition were measured before (pretest), at the end (11 months, posttest), and 1 year after the end (23 months, follow-up) of the interventions. The results from pretest to posttest have already been published. The current study analyzed the results from posttest to follow-up. There was a decrease in cardiorespiratory fitness, muscular fitness, and functional performance from posttest to follow-up in the structured intervention group but not in the control group or the lifestyle intervention group. At 23 months, participants in both groups still showed improvements in cardiorespiratory fitness. In addition, the structured group showed long-term improvements in muscular fitness, whereas the lifestyle group showed long-term improvements in functional performance. No long-term effects were found for blood pressure or body composition. These results highlight the potential of a structured fitness center-based intervention and a home-based lifestyle intervention in the battle against inactivity in older adults. Lifestyle programs are especially valuable because they require fewer resources and less time from health institutions and health practitioners. © 2011, Copyright the Authors.

Chemical and structural biology of protein lysine deacetylases

2017-01-01

Histone acetylation is a reversible posttranslational modification that plays a fundamental role in regulating eukaryotic gene expression and chromatin structure/function. Key enzymes for removing acetyl groups from histones are metal (zinc)-dependent and NAD+-dependent histone deacetylases (HDACs). The molecular function of HDACs have been extensively characterized by various approaches including chemical, molecular, and structural biology, which demonstrated that HDACs regulate cell proliferation, differentiation, and metabolic homeostasis, and that their alterations are deeply involved in various human disorders including cancer. Notably, drug discovery efforts have achieved success in developing HDAC-targeting therapeutics for treatment of several cancers. However, recent advancements in proteomics technology have revealed much broader aspects of HDACs beyond gene expression control. Not only histones but also a large number of cellular proteins are subject to acetylation by histone acetyltransferases (HATs) and deacetylation by HDACs. Furthermore, some of their structures can flexibly accept and hydrolyze other acyl groups on protein lysine residues. This review mainly focuses on structural aspects of HDAC enzymatic activity regulated by interaction with substrates, co-factors, small molecule inhibitors, and activators. PMID:28496053

Despite increasing demand for structured processes to guide clinical handover, nursing handover tools are limited in the intensive care unit. The study aim was to identify key items to include in a minimum dataset for intensive care nursing team leader shift-to-shift handover. This focus group study was conducted in a 21-bed medical/surgical intensive care unit in Australia. Senior registered nurses involved in team leader handovers were recruited. Focus groups were conducted using a nominal group technique to generate and prioritise minimum dataset items. Nurses were presented with content from previous team leader handovers and asked to select which content items to include in a minimum dataset. Participant responses were summarised as frequencies and percentages. Seventeen senior nurses participated in three focus groups. Participants agreed that ISBAR (Identify-Situation-Background-Assessment-Recommendations) was a useful tool to guide clinical handover. Items recommended to be included in the minimum dataset (≥65% agreement) included Identify (name, age, days in intensive care), Situation (diagnosis, surgical procedure), Background (significant event(s), management of significant event(s)) and Recommendations (patient plan for next shift, tasks to follow up for next shift). Overall, 30 of the 67 (45%) items in the Assessment category were considered important to include in the minimum dataset and focused on relevant observations and treatment within each body system. Other non-ISBAR items considered important to include related to the ICU (admissions to ICU, staffing/skill mix, theatre cases) and patients (infectious status, site of infection, end of life plan). Items were further categorised into those to include in all handovers and those to discuss only when relevant to the patient. The findings suggest a minimum dataset for intensive care nursing team leader shift-to-shift handover should contain items within ISBAR along with unit and patient specific information to maintain continuity of care and patient safety across shift changes.

Shared decision making (SDM) is particularly relevant in oncology, where complex treatment options with varying side effects may lead to meaningful changes in the patient's quality of life. For several years, health policies have called for the implementation of SDM, but SDM remains poorly implemented in routine clinical practice. Implementation science has highlighted the importance of assessing stakeholders' needs to inform the development of implementation programs. Thus, the aim of the present study was to assess different stakeholders' needs regarding the implementation of SDM in routine care. A qualitative study using focus groups and interviews was conducted. Focus groups were carried out with junior physicians, senior physicians, nurses and other healthcare providers (HPCs) (e.g. psycho-oncologists, physiotherapists), patients and family members. Head physicians as well as other HPCs in management positions were interviewed. Audiotapes of focus groups and interviews were transcribed verbatim and analyzed using content analysis. Six focus groups with a total of n = 42 stakeholders as well as n = 17 interviews were conducted. Focus groups and interviews revealed five main categories of needs to be fulfilled in order to achieve a better implementation of SDM in routine cancer care: 1) changes in communication, 2) involvement of other parties, 3) a trustful patient-physician relationship, 4) culture change and 5) structural changes. Stakeholders discussed four clusters of intervention strategies that could foster the implementation of SDM in routine cancer care: 1) clinician-mediated interventions, 2) patient-mediated interventions, 3) provision of patient information material and 4) the establishment of a patient advocate. Study results show that stakeholders voiced a diversity of needs to foster implementation of SDM in routine cancer care, of which some can be directly addressed by intervention strategies. Present results can be used to develop an implementation program to foster SDM in routine cancer care.

The impact of asthma and chronic obstructive pulmonary disease (COPD) on individuals' lives may be substantial, yet clinical practice often focuses only on symptoms. We aimed to better understand the perspective of asthma or COPD patients and to identify condition-related burden, life impact, priorities, unmet needs, and treatment goals. Individuals aged at least 18 years with asthma or COPD were identified by a recruitment panel via clinical referrals, support groups, consumer networks, and a patient database. Interviews were carried out individually (by telephone) or in focus groups (with no more than five participants per group). A semi-structured interview guide was used with prespecified topics, informed by a literature review, that were considered impactful in asthma or COPD (symptoms and daily-life impact, satisfaction with current treatment, important aspects of treatment, adherence, and ideal treatment). Overall, 72 people participated in focus groups/individual interviews (asthma n = 18/n = 21; COPD n = 15/n = 18). "Shortness of breath" was the most frequently reported symptom; however, participants discussed the life impact of their condition more than symptoms alone. Reported physical impacts included the inability to sleep and socialize, while emotional impacts included "embarrassment, stigma, and/or self-consciousness", "fear and/or panic", and "sadness, anxiety, and/or depression". Coping mechanisms for normal activities included continuing at reduced pace and avoidance. Treatment preferences centered on resolving impacts; improved sleep, "speed of action", and "length of relief" were the most frequently reported ideal treatment factors. Patients with asthma or COPD experience substantial quality of life limitations and tend to focus on these in their expressions of concern, rather than symptoms per se. Life impacts of these conditions may have implications beyond those commonly appreciated in routine practice; these considerations will be applied to a future discrete choice experiment survey.

A series of mononuclear Co(II)-flavonolate complexes [Co(II)L(R)(fla)] (L(R)H = 2-{[bis(pyridin-2-ylmethyl)amino]methyl}-p/m-R-benzoic acid; R = p-OMe (1), p-Me (2), m-Br (4), and m-NO2 (5); fla = flavonolate) were designed and synthesized as structural and functional models for the ES (enzyme-substrate) complexes to mimic the active site of the Co(II)-containing quercetin 2,3-dioxygenase (Co-2,3-QD). The metal center Co(II) ion in each complex shows a similar distorted octahedral geometry. The model complexes display high enzyme-type dioxygenation reactivity (oxidative O-heterocyclic ring opening of the coordinated substrate flavonolate) at low temperature, presumably due to the attached carboxylate group in the ligands. The reactivity exhibits a substituent group dependent order of -OMe (1) > -Me (2) > -H (3)14b > -Br (4) > -NO2 (5), and the Hammett plot is linear (ρ = -0.78). This can be explained as the electronic nature of the substituent group in the ligands may influence the conformation and redox potential of the bound flavonolate and finally bring different reactivity. The structures, properties, and reactivity of the model complexes show some dependence on the substituent group in the supporting model ligands, and there is some relationship among them. This study is the first example of a series of structural and functional ES models of Co-2,3-QD, with focus on the effects of the electronic nature of substituted groups and the carboxylate group of the ligands to the dioxygenation reactivity, that will provide important insights into the structure-property-reactivity relationship and the catalytic role of Co-2,3-QD.

[Analysis of barriers to therapeutic adherence for Colombian women with HIV/AIDS: a question of health rights].

To identify and analyze HIV/AIDS treatment adherence among Colombian women. A qualitative, descriptive-interpretative study with content analysis was developed between 2008 and 2009. Sixty six women participated in five focus group discussions. To complement data, semi-structured interviews with seven key informants were conducted. Main barriers are determined structurally by the current Colombian health system, based on insurance market. The right to access to treatment in a timely and continuous manner, the rights to confidentiality and non discrimination, and the right to quality care with gender focus are affected among participant women. Consequently, adherence is negatively affected. The current Colombian health system determines critical processes affecting HIV/AIDS treatment adherence in women. However, further research must be conducted to identify specific associations with non-universal health systems.

The demand for electrical energy storage (EES) is ever increasing, which calls for better batteries. NASICON-structured materials represent a family of important electrodes due to its superior ionic conductivity and stable structures. A wide range of materials have been considered, where both vanadium-based and titanium-based materials are recommended as being of great interest. NASICON-structured materials are suitable for both the cathode and the anode, where the operation potential can be easily tuned by the choice of transition metal and/or polyanion group in the structure. NASICON-structured materials also represent a class of solid electrolytes, which are widely employed in all-solid-state ion batteries, all-solid-state air batteries, and hybrid batteries. NASICON-structured materials are reviewed with a focus on both electrode materials and solid-state electrolytes. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Fullerene and its derivatives with different surface chemistry have great potential in biomedical applications. Accordingly, it is important to delineate the impact of these carbon-based nanoparticles on protein structure, dynamics, and subsequently function. Here, we focused on the effect of hydroxylation -- a common strategy for solubilizing and functionalizing fullerene -- on protein-nanoparticle interactions using a model protein, ubiquitin. We applied a set of complementary computational modeling methods, including docking and molecular dynamics simulations with both explicit and implicit solvent, to illustrate the impact of hydroxylated fullerenes on the structure and dynamics of ubiquitin. We found that all derivatives bound to the model protein. Specifically, the more hydrophilic nanoparticles with a higher number of hydroxyl groups bound to the surface of the protein via hydrogen bonds, which stabilized the protein without inducing large conformational changes in the protein structure. In contrast, fullerene derivatives with a smaller number of hydroxyl groups buried their hydrophobic surface inside the protein, thereby causing protein denaturation. Overall, our results revealed a distinct role of surface chemistry on nanoparticle-protein binding and binding-induced protein misfolding.Fullerene and its derivatives with different surface chemistry have great potential in biomedical applications.

Regarding the debate on the existence of two current focuses on health science research (qualitative and quantitative), the paper states the need for complementing the techniques which contribute to a better knowledge of populations and communities, and the need for offering effective solutions to different problems. The article analyses the usefulness of qualitative methods, describes the techniques and procedures more frequently used to guarantee the validity and reliability of research findings and ends bringing up the need for using qualitative and quantitative approaches. This way of working together or learning from each other will enrich research and interventions on public heath and health management fields. Qualitative methods are useful for sound understanding of a given issue that is being investigated or evaluated taking into account the point of view of the participants under research. Key techniques, listed from the most structured to the less structured are among others: structured interview, Delphi, nominal group, case study, semistructured interview, focal group, brainstorming, discussion group, in depth interview, life story and participant observation.

Genetic diversity and population structure of a Sichuan sika deer (Cervus sichuanicus) population in Tiebu Nature Reserve based on microsatellite variation

Cervus sichuanicus is a species of sika deer (Cervus nippon Group). To date, research has mainly focused on quantity surveying and behavior studies, with genetic information on this species currently deficient. To provide scientific evidence to assist in the protection of this species, we collected Sichuan sika deer fecal samples from the Sichuan Tiebu Nature Reserve (TNR) and extracted DNA from those samples. Microsatellite loci of bovine were used for PCR amplification. After GeneScan, the genotype data were used to analyze the genetic diversity and population structure of the Sichuan sika deer in TNR. Results showed that the average expected heterozygosity of the Sichuan sika deer population in TNR was 0.562, equivalent to the average expected heterozygosity of endangered animals, such as Procapra przewalskii. Furthermore, 8 of 9 microsatellite loci significantly deviated from the Hardy-Weinberg equilibrium and two groups existed within the Sichuan sika deer TNR population. This genetic structure may be caused by a group of Manchurian sika deer (Cervus hortulorum) released in TNR. PMID:25465089

To examine household food insecurity and coping mechanisms in two relatively politically stable states of South Sudan. Cross-sectional assessment including structured interviews and focus group discussions with food aid programme beneficiaries and staff. Structured interview findings were analysed with descriptive statistics using the statistical software package STATA version 11. Rural households in four payams (sub-county administrative districts) benefiting from a multi-year assistance programme funded by the US Agency for International Development. The study was conducted in January 2012, six months after independence. Study subjects included eighty mothers of children aged 6–23 months in structured interviews and eight focus groups, each with six to ten participants, of mothers of children aged 6–23 months. Ninety-three per cent of households surveyed in Warrap and 100% of households in Northern Bahr el Ghazal states were severely food access insecure. Nearly all households (97?5%) surveyed in both states reported there were months in 2011 without enough food to eat. The majority of households (88%) reported sometimes or often going to bed hungry in the month preceding the study. A number of coping mechanisms were used when households did not have enough food, including reduced meal size, skipping meals, selling assets and engaging in some kind business in order to generate money to buy food. Given the highly volatile political, economic and humanitarian situation in South Sudan, the priorities of the international community are understandably focused on securing greater stability in South Sudan and preventing humanitarian needs from escalating significantly. There is a need, however, for simultaneous emphasis on food assistance and longer-term development strategies throughout South Sudan, particularly in areas of agriculture, livelihoods and food security.

A purposive sample of 14 immigrants living in Ontario, Canada, participated in two focus groups. The researchers used semi-structured interviews to collect data and five themes emerged from the data: beliefs about diabetes were centered on diverse factors, preserving culture through food preferences and preparation, cultural practices to stay healthy, cultural practices determined number of servings of fruit and vegetables per day, and engaging in physical activity to stay healthy. Findings indicated how health beliefs and cultural practices influenced behavior in preventing type 2 diabetes (T2D). Future research should focus on other high-risk minority groups (South Asian, Caribbean, and Latin American) to examine their health beliefs and cultural practices and use these finding to develop best practice guidelines, which should be incorporated into culturally tailored interventions. © The Author(s) 2015.

The objective of this pilot study was to understand, from the Vaccines for Children (VFC) program provider's perspective, issues relating to vaccine access and compliance for Hispanic adolescents in a rural setting. Researchers conducted individual structured interviews with VFC providers and focus groups with Hispanic immigrant parents in rural southern Georgia. Overall, the VFC providers said that their Hispanic patients were very positive toward vaccines in general, but there were cost issues related to stocking the vaccine and reaching the Hispanic population. The focus group discussions revealed that most Hispanic parents were not aware of the existence of the human papilloma virus (HPV) vaccine, nor had they heard about the VFC program. Numerous vaccination barriers continue to impact HPV vaccine uptake in the Hispanic immigrant population in the US South.

Focus groups were conducted with individuals involved in prenatal diagnosis to determine their opinions relating to whole exome sequencing in fetuses with structural anomalies. Five representatives of patient groups/charities (PRGs) and eight clinical professionals (CPs) participated. Three focus groups occurred (the two groups separately and then combined). Framework analysis was performed to elicit themes. A thematic coding frame was identified based on emerging themes. Seven main themes (consent, analysis, interpretation/reinterpretation of results, prenatal issues, uncertainty, incidental findings and information access) with subthemes emerged. The main themes were raised by both groups, apart from 'analysis', which was raised by CPs only. Some subthemes were raised by PRGs and CPs (with different perspectives). Others were raised either by PRGs or CPs, showing differences in patient/clinician agendas. Prenatal consent for whole exome sequencing is not a 'perfect' process, but consent takers should be fully educated regarding the test. PRGs highlighted issues involving access to results, feeling that women want to know all information. PRGs also felt that patients want reinterpretation of results over time, whilst CPs felt that interpretation should be performed at the point of testing only. © 2016 John Wiley & Sons, Ltd. © 2016 John Wiley & Sons, Ltd.

High school students' views of learning chemistry concepts with analogies

NASA Astrophysics Data System (ADS)

Mathews, Jeffrey A.

Analogies are often used in teaching abstract chemistry concepts, however few studies are concerned with how students actually view learning with analogies. An eight-member focus group, consisting of high school students, described the process of learning with analogies and how aware they were of their own learning. The students attended four analogy presentations and completed written responses, attended focus groups, and participated in repeated individual interview sessions throughout this eight-week, emic, phenomenological study. This study utilized an interpretive, qualitative methodology using a constant comparative, inductive analysis design. Students from a suburban high school in the southeastern United States were selected by purposeful sampling involving a concepts pre-test and an analogy presentation used to determine an eight member focus group. The focus group meetings were videotaped and emergent, semi-structured individual interviews were audio taped, transcribed and coded. Personal student journals, field notes, and a reflective journal were used to triangulate the study. Open, axial, and selective coding were used for data analysis and interpretation. Students described the process of learning with analogies as being able to visually see connections or picture mental images of familiar and unfamiliar concepts. Students pointed out the significance of investigating analogy breakdowns and described accommodation of new information as either automatic, which according to students resulted in memorization and hard learning, or quite laborious, which resulted in understanding and soft learning. Results indicated that students gave themselves more permission to ask questions and be critical of the teaching they are experiencing when their views were given merit. Implications for teachers include insight on students' views of learning and students' self-awareness.

To examine FPs' training needs for conducting decision-making capacity assessments (DMCAs) and to determine how training materials, based on a DMCA model, can be adapted for use by FPs. A scoping review of the literature and qualitative research methodology (focus groups and structured interviews). Edmonton, Alta. Nine FPs, who practised in various settings, who chose to attend a focus group on DMCAs. A scoping review of the literature to examine the current status of physician education regarding assessment of decision-making capacity, and a focus group and interviews with FPs to ascertain the educational needs of FPs in this area. Based on the scoping review of the literature, 4 main themes emerged: increasing saliency of DMCAs owing to an aging population, suboptimal DMCA training for physicians, inconsistent approaches to DMCA, and tension between autonomy and protection. The findings of the focus groups and interviews indicate that, while FPs working as independent practitioners or with interprofessional teams are motivated to engage in DMCAs and use the DMCA model for those assessments, several factors impede their conducting DMCAs. The most notable barriers were a lack of education, isolation from interprofessional teams, uneasiness around managing conflict with families, fear of liability, and concerns regarding remuneration. This pilot study has helped to inform ways to better train and support FPs in conducting DMCAs. Family physicians are well positioned, with proper training, to effectively conduct DMCAs. To engage FPs in the process, however, the barriers should be addressed. Copyright© the College of Family Physicians of Canada.

Purpose The purpose of the study was to explore and understand knowledge and attitudes about food, diet, and weight control, focusing on barriers and motivators to reduce risk of developing type 2 diabetes. Methods Six focus groups were conducted in May and June 2010. The groups were stratified by sex. A total of 35 ethnically diverse samples with a high risk for type 2 diabetes participated. The average age was 51 ± 10.6 years, and 57% of the sample represented women. Results Four themes emerged from the focus groups: (1) demonstrated knowledge and source of knowledge, including participants’ basic understanding of “good” and “bad” food and what constitutes a “healthy diet” and trusted sources of information; (2) perceptions of food and diet, encompassing how participants expressed their perception of and interaction with food and diet; (3) sense of control over dietary intake, reflecting participants’ discussion of their perceived ability to control their eating patterns and food choices; and (4) eating behaviors, describing participants’ patterns of eating and perceived barriers to eating a healthy diet. Conclusions Study findings demonstrate that eating healthy requires a complex interaction between individual perceptions of food and sense of control over eating patterns and socio-political and economic structural factors that restrict healthy eating options while promoting unhealthy ones. Programs for long-term eating behavioral change necessary to reduce type 2 diabetes and obesity need to incorporate strategies that address individual-level factors of perception of food and sense of control over eating patterns, as well as structural level factors such as poverty and food insecurity.

The subspecialty consultation represents a potentially powerful opportunity for resident learning, but barriers may limit the educational exchanges between fellows (subspecialty registrars) and residents (house officers). We conducted a focus group study of internal medicine (IM) residents and subspecialty fellows to determine barriers against and factors facilitating resident-fellow teaching interactions on the wards, and to identify opportunities for maximising teaching and learning. We conducted four focus groups of IM residents (n = 18) and IM subspecialty fellows (n = 16) at two academic medical centres in the USA during February and March 2013. Participants represented trainees in all 3 years of residency training and seven IM subspecialties. Four investigators analysed the transcripts using a structured qualitative framework approach, which was informed by literature on consultation and the theoretical framework of activity theory. We identified two domains of barriers and facilitating factors: personal and systems-based. Sub-themes in the personal domain included fellows' perceived resistance to consultations, residents' willingness to engage in teaching interactions, and perceptions and expectations. Sub-themes in the systems-based domain included the process of requesting the consult, the quality of the consult request, primary team structure, familiarity between residents and fellows, workload, work experience, culture of subspecialty divisions, and fellows' teaching skills. These barriers differentially affected the two stages of the consult identified in the focus groups (initial interaction and follow-up interaction). Residents and fellows want to engage in positive teaching interactions in the context of the clinical consult; however, multiple barriers influence both parties in the hospital environment. Many of these barriers are amenable to change. Interventions aimed at reducing barriers to teaching in the setting of consultation hold promise for improving teaching and learning on the wards. © 2015 John Wiley & Sons Ltd.

The role of women in the donation consent decision: building on previous research.

Recently published findings emphasize the dominant role of women in the donation discussion. With some noteworthy exceptions, the empirical literature on gender and donation, and the role of gender in healthcare decisions as well as donation, is limited. To provide preliminary information needed to begin theoretical or framework development and to initiate more rigorous research on the role of gender in donation discussions. This exploratory study is a descriptive qualitative retrospective study using focus group methodology. Two focus groups were conducted in 2 major cities in the organ procurement organization's service area. Participants were women who were involved in the donation discussion within the past 5 years; 6 participated in 1 session, 8 in the other. The focus group discussions highlight the role of women in the donation process relative to information needs, information usage, and the ensuring dynamics of the donation discussion. Compared to men, women tend to seek more information and reframe this information for others. Because women are frequently central in family communication networks, they serve as a communication conduit for other family members and may influence others. Involving key women decision makers in the early stages of the donation discussion and providing information elaboration build on women's central placement and role in family communication network processes. The significance of women's central placement may carry cultural implications, particularly for racial or ethnic groups with strong matriarchal or extended kinship structures.

ABSTRACT Background: Haiti’s 2010 earthquake devastated social, health, and economic infrastructure and left 2 million persons homeless. Over 6 years later 61,000 people remain displaced, most lacking protection, services, and durable solutions. Structural contexts elevate risks of gender-based violence (GBV) targeting internally displaced (ID) girls and women. Objective: We used an intersectionality framework to explore lived experiences and understanding of violence among ID young men and women in Leogane, Haiti. Methods: We conducted six focus groups, three with ID young women (n = 30) and three with ID young men (n = 30) aged 18–24 years, and 11 in-depth individual interviews with frontline workers in Leogane. Focus groups and interviews were conducted in Kreyol, transcribed verbatim, translated into English, and analyzed using narrative thematic techniques. Results: Findings revealed violence experienced by ID youth was (re)produced at the intersection of gender, poverty, displacement, and age. Multi-level forms of violence included structural (e.g. poverty), community (e.g. gender norms, and interpersonal (e.g. family expectations) dimensions. Coping strategies spanned intrapersonal (hope), community (social support), and structural (employment/education) dimensions. Conclusions: Interventions to reduce violence should be tailored to address the social inequities that emerge at the intersection of youth, poverty, displacement, and hegemonic gender norms.

Structural stigma: Research evidence and implications for psychological science.

PubMed

Hatzenbuehler, Mark L

2016-11-01

Psychological research has provided essential insights into how stigma operates to disadvantage those who are targeted by it. At the same time, stigma research has been criticized for being too focused on the perceptions of stigmatized individuals and on microlevel interactions, rather than attending to structural forms of stigma. This article describes the relatively new field of research on structural stigma, which is defined as societal-level conditions, cultural norms, and institutional policies that constrain the opportunities, resources, and well-being of the stigmatized. I review emerging evidence that structural stigma related to mental illness and sexual orientation (a) exerts direct and synergistic effects on stigma processes that have long been the focus of psychological inquiry (e.g., concealment, rejection sensitivity), (b) serves as a contextual moderator of the efficacy of psychological interventions, and (c) contributes to numerous adverse health outcomes for members of stigmatized groups-ranging from dysregulated physiological stress responses to premature mortality-indicating that structural stigma represents an underrecognized mechanism producing health inequalities. Each of these pieces of evidence suggests that structural stigma is relevant to psychology and therefore deserves the attention of psychological scientists interested in understanding and ultimately reducing the negative effects of stigma.

The interactions between surfactants and enzymes and their impact on the catalytic efficiency represent a central problem and were here evaluated using circular dichroism, dynamic light scattering, and enzyme activity determinations. This work focuses on this key issue by evaluating the role of the ethyleneoxide (EO) groups of anionic surfactants on the structure and activity of a commercial lipase, and by focusing on the protein/surfactant interactions at a molecular level. The conformational changes and enzymatic activity of the protein were evaluated in the presence of sodium dodecyl sulfate (SDS also denoted as SLE 0 S) and of sodium lauryl ether sulfate with two EO units (SLE 2 S). The results strongly suggest that the presence of EO units in the surfactant polar headgroup determines the stability and the activity of the enzyme. While SDS promotes enzyme denaturation and consequent loss of activity, SLE 2 S preserves the enzyme structure and activity. The data further highlights that the electrostatic interactions among the protein groups are changed by the presence of the adsorbed anionic surfactants being such absorption mainly driven by hydrophobic interactions. © 2016 American Institute of Chemical Engineers Biotechnol.

Using machine learning to identify structural breaks in single-group interrupted time series designs.

PubMed

Linden, Ariel; Yarnold, Paul R

2016-12-01

Single-group interrupted time series analysis (ITSA) is a popular evaluation methodology in which a single unit of observation is being studied, the outcome variable is serially ordered as a time series and the intervention is expected to 'interrupt' the level and/or trend of the time series, subsequent to its introduction. Given that the internal validity of the design rests on the premise that the interruption in the time series is associated with the introduction of the treatment, treatment effects may seem less plausible if a parallel trend already exists in the time series prior to the actual intervention. Thus, sensitivity analyses should focus on detecting structural breaks in the time series before the intervention. In this paper, we introduce a machine-learning algorithm called optimal discriminant analysis (ODA) as an approach to determine if structural breaks can be identified in years prior to the initiation of the intervention, using data from California's 1988 voter-initiated Proposition 99 to reduce smoking rates. The ODA analysis indicates that numerous structural breaks occurred prior to the actual initiation of Proposition 99 in 1989, including perfect structural breaks in 1983 and 1985, thereby casting doubt on the validity of treatment effects estimated for the actual intervention when using a single-group ITSA design. Given the widespread use of ITSA for evaluating observational data and the increasing use of machine-learning techniques in traditional research, we recommend that structural break sensitivity analysis is routinely incorporated in all research using the single-group ITSA design. © 2016 John Wiley & Sons, Ltd.

Do structural changes (eg, collagen/matrix) explain the response to therapeutic exercises in tendinopathy: a systematic review.

Previous reviews have highlighted the benefit of loaded therapeutic exercise in the treatment of tendinopathy. Changes in observable structural outcomes have been suggested as a possible explanation for this response to therapeutic exercise. However, the mechanism for the efficacy of therapeutic exercise remains unclear. To systematically review the relationship between the observable structural change and clinical outcomes following therapeutic exercise. An electronic search of AMED, CiNAHL, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PEDro and SPORTDiscus was undertaken from their inception to June 2012. Any study design that incorporated observable structural outcomes and clinical outcomes when assessing the effect of therapeutic exercise on participants with tendinopathy. Included studies were appraised for risk of bias using the tool developed by the Cochrane Back Review Group. Due to heterogeneity of studies, a qualitative synthesis was undertaken. Twenty articles describing 625 patients were included. Overall, there is a strong evidence to refute any observable structural change as an explanation for the response to therapeutic exercise when treated by eccentric exercise training. Moderate evidence does exist to support the response of heavy-slow resistance training (HSR). The available literature does not support observable structural change as an explanation for the response of therapeutic exercise except for some support from HSR. Future research should focus on indentifying other explanations including neural, biochemical and myogenic changes. Registered with PROSPERO, registration number CRD42011001638.

Phenomenon: International medical graduates (IMGs) play a key role in host countries' health systems but face unique challenges, which makes effective, tailored support for IMGs essential. Prior literature describing the acculturation needs of IMGs focused primarily on communication content and style. We conducted a qualitative study to explore acculturation that might be specific to IMG residents who care for children. In a study conducted from November 2011 to April 2012, we performed four 90-minute semistructured focus groups with 26 pediatric IMG residents from 12 countries. The focus group transcripts were analyzed using open and focused coding methodology. The focus groups and subsequent analysis demonstrated that pediatric IMG residents' socialization to their home culture impacts their transition to practice in the United States; they must adjust not only to a U.S. culture, different from their own, but also to the culture of medicine in the United States. We identified the following new acculturation themes: understanding the education system and family structure, social determinants of health, communication with African American parents, contraception, physician handoffs, physicians' role in prevention, adolescent health, and physicians' role in child advocacy. We further highlight the acculturation challenges faced by pediatric IMG residents and offer brief recommendations for the creation of a deliberate acculturation curriculum for pediatric IMG residents. Insight: Residency training is a unique period in physicians' personal and professional development and can be particularly challenging for IMGs. There is a significant gap in the identified acculturation needs and the current curricula available to IMG residents who care for children.

The changes in Washington State and Colorado marijuana laws call for the development of new brief family-focused adolescent marijuana use preventive interventions that are relevant for and tailored to the context of legalization for retail sale. To that end, focus groups with parents and teens were conducted to find out about their concerns and needs in the context of legalization. Six semi-structured focus groups (3 with parents, 3 with teens) were conducted in Washington State in 2013 related to consequences of teen marijuana use and messages that would be effective in helping to prevent teens from using marijuana in the context of legal adult use. A total of 33 teens and 35 parents participated. Three primary themes were common to these parents and teens: the negative consequences of marijuana use during adolescence on mental, physical, and social health; the need for more or better information; and the need for information/messages to come from trusted sources. The themes related to potential prevention messages include the use of fear; stories about real people; focusing on short-term consequences; and teens needing alternative activities (something better to do). The results suggest that parents and teens need information about the new retail marijuana legalization law. Teens are open to both information and guidance from parents as long as it is calm and respectful. Firsthand accounts of consequences of marijuana use from peers and adults, rather than threats from authority figures, could hold some promise for persuading teens to avoid marijuana use.

Classification of proteins: available structural space for molecular modeling.

PubMed

Andreeva, Antonina

2012-01-01

The wealth of available protein structural data provides unprecedented opportunity to study and better understand the underlying principles of protein folding and protein structure evolution. A key to achieving this lies in the ability to analyse these data and to organize them in a coherent classification scheme. Over the past years several protein classifications have been developed that aim to group proteins based on their structural relationships. Some of these classification schemes explore the concept of structural neighbourhood (structural continuum), whereas other utilize the notion of protein evolution and thus provide a discrete rather than continuum view of protein structure space. This chapter presents a strategy for classification of proteins with known three-dimensional structure. Steps in the classification process along with basic definitions are introduced. Examples illustrating some fundamental concepts of protein folding and evolution with a special focus on the exceptions to them are presented.

Solomon, Patricia; Risdon, Cathy

2011-01-01

The home care setting is ideal for medical students to learn about the importance of interprofessional collaboration in the community. This project examined the impact of a unique program designed to facilitate medical students' knowledge and awareness of the challenges of interprofessional care in the home. In pairs, medical students participated in two community visits with preceptors from different professions. Students completed a structured personal reflection after their first visit. Students and preceptors participated in focus groups or interviews to identify strengths and challenges of the experiences. The structured reflections and the focus group and interview transcripts were analyzed qualitatively. 164 medical students and 36 preceptors participated in 326 visits. There were high ratings of satisfaction from students and preceptors. Students developed unexpected insights into peoples' lives, developed a greater understanding of the patient's perspective and determinants of health, learned about others' scope of practice, and developed an appreciation of the limitations of their own scope of practice. Preceptors had high expectations for student performance and engagement and enjoyed the opportunity to impart their knowledge to future physicians. Although organizationally complex, the program evaluation suggestions that students and preceptors benefit from interprofessional experiences in the home.

Teens do not meet guidelines for healthy eating and physical activity. The Internet may be an effective method for delivering programs that help them adopt healthy behaviors. To collect information to design content and structure for a teen-friendly website promoting healthy eating and physical activity behaviors. Qualitative research, encompassing both focus group and interview techniques, were used to design the website. Participants were 12-17 year olds in Houston, Texas, and West Lafayette, Indiana. A total of 133 participants took part in 26 focus groups while 15 participated in one-on-one interviews to provide guidance for the development of teen-friendly content and structure for an online behavior change program promoting healthy eating and physical activity to 12-17 year olds. The youth made suggestions to overcome common barriers to healthy eating and physical activity. Their feedback was used to develop "Teen Choice: Food & Fitness," a 12-week online behavior change program, populated by 4 cartoon character role models. It is critical that members of the target audience be included in formative research to develop behavior change programs that are relevant, appealing, and address their needs and interests.

Alzheimer's disease and the law: positive and negative consequences of structural stigma and labeling in the legal system.

Werner, Perla; Doron, Israel Issi

2017-11-01

To explore the meaning and consequences of labeling on structural stigma in the context of Alzheimer's disease (AD) in the legal system. This qualitative study was made up of three focus groups including social workers and lawyers (n = 26). Participants were asked to report their experience in circumstances in which persons with AD and their family members engage with the legal system. Thematic analysis using the constant comparative method was used. The discussions in the focus groups raised two overall themes. (1) The significance of the medical diagnostic labeling of AD in the legal system and (2) the consequences of labeling of AD within the legal system. This last theme included four sub-themes: (a) negative consequences of labeling; (b) reasons associated with negative consequences of labeling; (c) positive consequences of labeling; and (d) reasons associated with positive consequences of labeling. Findings of the study provide a first foundation for future research on the meaning and consequences of labeling in legal cases involving persons with AD. They suggest that increasing judges' knowledge about AD and reforming the existing 'status-based' legal capacity legislation might benefit by limiting the legal weight given today to the medical diagnosis.

Little research exists regarding men who have sex with men and sexual risk in Nigeria. Prior to the implementation of a targeted HIV/STI prevalence study, structured focus groups incorporating anonymous questionnaires were conducted with members of this population in secure locations in Nigeria. A purposive sample of men was recruited by word-of-mouth. Five focus groups were conducted with a total of 58 men. Mean age was 27 years (range 16-58); 60% had post-secondary education; 56% were employed full or part-time; 83% were Christian; 16% were Muslim; 66% self-identified as bisexual; 31% as homosexual. Participants' experiences were diverse, with ethnic, religious and class distinctions strongly structuring sexual expression. Same-sex community networks were hidden, with social activities taking place in non-commercial, private venues. Socially ostracized by culture, religion, and political will, the risks embodied within same-sex activity are high. For Nigeria--a nation culturally rich and religiously devout--the implications for public health policy are complex. However, these research findings suggest that immediate action is vital to mitigate the impacts of HIV and other STIs.

To understand how implementing a daily team huddle affected the function of a complex interprofessional team including learners. A qualitative descriptive study using semi-structured interviews in focus groups. An academic general practice teaching practice. All members of one interprofessional team, including nurses, general practitioners, junior doctors, and support staff. Focus group interviews using semi-structured guidance were transcribed and the results analysed using qualitative content analysis. Four interrelated themes were identified: communication and knowledge sharing; efficiency of care; relationship and team building; and shared responsibility for team function. The implementation of the daily team huddle was seen by participants to enhance the collaboration within the team and to contribute to work life enjoyment. Participants perceived that problems were anticipated and solved quickly. Clinical updates and information about patients benefited the team including learners. Junior doctors quickly understood the scope of practice of other team members, but some felt reluctant to offer clinical opinions. The implementation of a daily team huddle was viewed as worthwhile by this large interprofessional general practice team. The delivery of patient care was more efficient, knowledge was readily distributed, and problem solving was shared across the team, including junior doctors.

Enhancement of maximum attainable ion energy in the radiation pressure acceleration regime using a guiding structure

Radiation Pressure Acceleration is a highly efficient mechanism of laser driven ion acceleration, with the laser energy almost totally transferrable to the ions in the relativistic regime. There is a fundamental limit on the maximum attainable ion energy, which is determined by the group velocity of the laser. In the case of a tightly focused laser pulses, which are utilized to get the highest intensity, another factor limiting the maximum ion energy comes into play, the transverse expansion of the target. Transverse expansion makes the target transparent for radiation, thus reducing the effectiveness of acceleration. Utilization of an external guidingmore » structure for the accelerating laser pulse may provide a way of compensating for the group velocity and transverse expansion effects.« less

Structural methodologies for auditing SNOMED.

Wang, Yue; Halper, Michael; Min, Hua; Perl, Yehoshua; Chen, Yan; Spackman, Kent A

2007-10-01

SNOMED is one of the leading health care terminologies being used worldwide. As such, quality assurance is an important part of its maintenance cycle. Methodologies for auditing SNOMED based on structural aspects of its organization are presented. In particular, automated techniques for partitioning SNOMED into smaller groups of concepts based primarily on relationships patterns are defined. Two abstraction networks, the area taxonomy and p-area taxonomy, are derived from the partitions. The high-level views afforded by these abstraction networks form the basis for systematic auditing. The networks tend to highlight errors that manifest themselves as irregularities at the abstract level. They also support group-based auditing, where sets of purportedly similar concepts are focused on for review. The auditing methodologies are demonstrated on one of SNOMED's top-level hierarchies. Errors discovered during the auditing process are reported.

An SAR study that identified a series of thienopyridine-based potent IkappaB Kinase beta (IKKbeta) inhibitors is described. With focuses on the structural optimization at C4 and C6 of structure 1 (Fig. 1), the study reveals that small alkyl and certain aromatic groups are preferred at C4, whereas polar groups with proper orientation at C6 efficiently enhance compound potency. The most potent analogues inhibit IKKbeta with IC50s as low as 40 nM, suppress LPS-induced TNF-alpha production in vitro and in vivo, display good kinase selectivity profiles, and are active in a HeLa cell NF-kappaB reporter gene assay, demonstrating that they directly interfere with the NF-kappaB signaling pathway.

Using participatory epidemiology to assess factors contributing to common enteric pathogens in Ontario: results from a workshop held at the Ontario Veterinary College, University of Guelph, Ontario

PubMed Central

2014-01-01

Background Common enteric pathogens that cause gastrointestinal illness are transmitted to humans through food, water or direct contact. This poses a significant concern to public health as enteric pathogens can cause disease in a large number of people, and cost a substantial amount to treat and prevent. In order to gain a better understanding of the occurrence of enteric disease in Ontario, this study explored public health professionals’ perceptions of major contributing factors for common enteric pathogens. Methods A case study was conducted as part of a two week training workshop in Participatory Epidemiology held at the Ontario Veterinary College, University of Guelph, in May 2013. Eight semi-structured interviews and four focus groups were conducted with representatives from the Public Health Agency of Canada, the University of Guelph, and three health regions in Southern Ontario. Written notes and pictures captured the qualitative information provided. Results were then analyzed using the mixed methods techniques of triangulation, convergence, and paradox. Results A total of fifty factors that contribute to enteric disease were identified across all interviews and focus groups. These contributing factors were grouped into key themes (travel, food handling, industry (farm-to-fork), water, geography, demographics, and behaviours) and were categorized as either a risk factor or susceptibility factor. Informants emphasized the complex relationships between the identified factors, and highlighted why these complexities make it difficult to determine where and how a person most likely acquired an enteric pathogen. Workshop participants observed differences in the type and quality of information collected during interviews and focus groups; we hypothesize that this may be attributed to the dynamics between group members (i.e. focus group discussions) as opposed to one-on-one interviews. Conclusions The information gathered will serve as a starting point to further explore contributing factors for common enteric pathogens. The identified complexities would be best explored by conducting additional surveillance, as well as interviews and focus groups with a more diverse group of stakeholders. This type of qualitative study can enhance knowledge of enteric pathogen surveillance and contribute to the development of resources and initiatives to holistically address the occurrence of gastrointestinal illness.

To compare the short-term effects of two physiotherapy approaches for improving ability to walk in different environments following stroke: (i) interventions based on the Bobath concept, in conjunction with task practice, compared to (ii) structured task practice alone. Randomized controlled trial. Two rehabilitation centres Participants: Twenty-six participants between four and 20 weeks post-stroke, able to walk with supervision indoors. Both groups received six one-hour physiotherapy sessions over a two-week period. One group received physiotherapy based on the Bobath concept, including one hour of structured task practice. The other group received six hours of structured task practice. The primary outcome was an adapted six-minute walk test, incorporating a step, ramp and uneven surface. Secondary measures were gait velocity and the Berg Balance Scale. Measures were assessed before and after the intervention period. Following the intervention, there was no significant difference in improvement between the two groups for the adapted six-minute walk test (89.9 (standard deviation (SD) 73.1) m Bobath versus 41 (40.7) m task practice, P = 0.07). However, walking velocity showed significantly greater increases in the Bobath group (26.2 (SD 17.2) m/min versus 9.9 (SD = 12.9) m/min, P = 0.01). No significant differences between groups were recorded for the Berg Balance Scale (P = 0.2). This pilot study indicates short-term benefit for using interventions based on the Bobath concept for improving walking velocity in people with stroke. A sample size of 32 participants per group is required for a definitive study.

Over the last years, several research groups have focused on developing efficient thermochemical heat storage (THS) systems, in-principle capable of being coupled with next generation high temperature Concentrated Solar Power plants. Among systems studied, the Co3O4/CoO redox system is a promising candidate. Currently, research efforts extend beyond basic level identification of promising materials to more application-oriented approaches aiming at validation of THS performance at pilot scale reactors. The present work focuses on the investigation of cobalt oxide based honeycomb structures as candidate reactors/heat exchangers to be employed for such purposes. In the evaluation conducted and presented here, cobalt oxide-based structures with different composition and geometrical characteristics were subjected to redox cycles in the temperature window between 800 and 1000°C under air flow. Basic aspects related to redox performance of each system are briefly discussed but the main focus lies on the evaluation of the segments structural stability after multi-cyclic operation. The latter is based on macroscopic visual observation and also supplemented by pre- (i.e. fresh samples) and post-characterization (i.e. after long term exposure) of extruded honeycombs via combined mercury porosimetry and SEM analysis.

To investigate different professionals' (nurse anaesthetists', anaesthesiologists', and postanaesthesia care unit nurses') descriptions of and reflections on the postoperative handover. A focus group interview study with a descriptive design using qualitative content analysis of transcripts. One anaesthetic clinic at two hospitals in Sweden. Six focus groups with 23 healthcare professionals involved in postoperative handovers. Each group was homogeneous regarding participant profession, resulting in two groups per profession: nurse anaesthetists (n=8), anaesthesiologists (n=7) and postanaesthesia care unit nurses (n=8). Patterns and five categories emerged: (1) having different temporal foci during handover, (2) insecurity when information is transferred from one team to another, (3) striving to ensure quality of the handover, (4) weighing the advantages and disadvantages of the bedside handover and (5) having different perspectives on the transfer of responsibility. The professionals' perceptions of the postoperative handover differed with regard to temporal foci and transfer of responsibility. All professional groups were insecure about having all information needed to ensure the quality of care. They strived to ensure quality of the handover by: focusing on matters that deviated from the normal course of events, aiding memory through structure and written information and cooperating within and between teams. They reported that the bedside handover enhances their control of the patient but also that it could threaten the patient's privacy and that frequent interruptions could be disturbing. The present findings revealed variations in different professionals' views on the postoperative handover. Healthcare interventions are needed to minimise the gap between professionals' perceptions and practices and to achieve a shared understanding of postoperative handover. Furthermore, to ensure high-quality and safe care, stakeholders/decision makers need to pay attention to the environment and infrastructure in postanaesthesia care. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To explore the research culture of nurses and allied health professionals (AHPs) in the UK and the influence of a dedicated research strategy and funding. It is important to understand the culture in order to effectively promote evidence-based patient care. The primary aim of this research was to explore the influence of research-focused exposure on the research culture of nurses and AHPs in the UK and to identify whether there was a difference in the research culture between a research-focused and non-research-focused clinical area (City and Riverside Hospitals). This is a unique and novel study that explored and compared the research culture stance of both AHPs and nurses. METHODS: A mixed methods design was used in this study. Tools used included the "Research Capacity and Culture tool" as an online survey, three focus group discussions and five semi-structured interviews with senior managers. Focus groups included research-naive groups from both hospitals and a research-active group from City Hospital. There were 224 responses received from 941 surveys with a 24% response rate. Descriptive statistics of the survey results indicated that there was a difference (p = .001) in the mean score of the research culture between City Hospital (5.35) and Riverside Hospital (3.90), but not between nurses and AHPs (p = .12). Qualitative data findings from the framework analysis were congruent and supported the survey results. The results provided empirical evidence to support a whole-level approach in order to improve the research culture. Both findings showed that there may not be any difference in the research culture between professional groups. Importantly, new evidence is presented to suggest that there were crucial communication issues which were hampering the research culture and there was a lack of support at the middle management level which needed to be tackled to improve the research culture of nurses and AHPs. The study highlighted the need to include a whole-level approach in organisation to improve research culture and to include communication within the Cooke's framework if evidence-based practice is to influence the quality of patient care. © 2018 John Wiley & Sons Ltd.

Aims and method There is very little research into the challenges of training in intellectual disability psychiatry or into interventions which may address these challenges. Using focus groups, we explored the experiences of intellectual disability psychiatry trainees, and evaluated a leaderless trainee support group developed in Bristol. Results Five distinct themes were identified via framework analysis: that trainees felt unprepared for the difference from previous posts; the need for support; the value of the group; that trainees were concerned about judgement in supervision; that the group structure was valued. Clinical implications Our findings highlight the support needs specific to intellectual disability psychiatry trainees. Leaderless peer support groups may be a valued resource to address such issues, and may be a useful model to be considered by other training schemes. PMID:28811919

Community-based clergy are highly engaged in helping seriously ill patients address spiritual concerns at the end of life (EOL). While they desire EOL training, no data exist in guiding how to conceptualize a clergy-training program. The objective of this study was used to identify best practices in an EOL training program for community clergy. As part of the National Clergy Project on End-of-Life Care, the project conducted key informant interviews and focus groups with active clergy in five US states (California, Illinois, Massachusetts, New York, and Texas). A diverse purposive sample of 35 active clergy representing pre-identified racial, educational, theological, and denominational categories hypothesized to be associated with more intensive utilization of medical care at the EOL. We assessed suggested curriculum structure and content for clergy EOL training through interviews and focus groups for the purpose of qualitative analysis. Thematic analysis identified key themes around curriculum structure, curriculum content, and issues of tension. Curriculum structure included ideas for targeting clergy as well as lay congregational leaders and found that clergy were open to combining resources from both religious and health-based institutions. Curriculum content included clergy desires for educational topics such as increasing their medical literacy and reviewing pastoral counseling approaches. Finally, clergy identified challenging barriers to EOL training needing to be openly discussed, including difficulties in collaborating with medical teams, surrounding issues of trust, the role of miracles, and caution of prognostication. Future EOL training is desired and needed for community-based clergy. In partnering together, religious-medical training programs should consider curricula sensitive toward structure, desired content, and perceived clergy tensions.

In recent years renewed interest in health-related stigma has underscored the importance of better understanding the structural underpinnings of stigma processes. This study investigated the influence of sociocultural context on perceived components of tuberculosis-related stigma in non-affected persons by comparing Haitians living in South Florida, USA, with Haitians residing in Léogane Commune, Haiti. Using the methods of cultural epidemiology, a two-phase study based on fieldwork between 2004–07 collected ethnographic data on the cultural context and components of tuberculosis (TB) stigma, and administered a stigma scale developed specifically for these populations. Thematic analysis of stigma components expressed in interviews, focus groups and observation revealed commonalities as well as distinctive emphases of TB stigma in the two comparison groups. Factor analyses of stigma scale scores confirmed the thematic differences revealed in ethnographic findings and highlight the influence of political and economic factors in shaping the meaning and experience of illness. Perceived components of TB stigma among Haitians in South Florida incorporated aspects of Haitian identity as a negatively stereotyped minority community within the larger society, while in Haiti, stigma was associated primarily with poverty, malnutrition, and HIV co-infection. Discussion of findings focuses on the social production of perceived and anticipated stigma as it is influenced by structural forces including the influences of politics, economics, institutional policies, and health service delivery structures. The findings also demonstrate the value of a transnational framework encompassing both sending and receiving countries for understanding TB related stigma in immigrant communities. PMID:20724052

The term social accountability has gained increased interest in medical education, but is relatively unexplored in dentistry. The aim of this study is to explore dental students' attitudes towards social accountability. A qualitative study utilizing focus groups with University of Otago final year (5th year) Bachelor of Dental Surgery (BDS) students was carried out. A questionnaire designed to measure medical students' attitudes towards social responsibility was used as a guide. Following data collection, framework analysis was used to analyze each of the three focus groups, and repeating themes were noted. Analysis of the focus groups discovered recurring themes, such that participants believed that dentists should be accountable to society in a professional context and that they are responsible for patients who present at their clinic but that there is no professional obligation to help reduce oral health inequalities by working with populations facing inequalities. There was strong agreement that there needs to be change to the dental health care system from a structural and political level to address oral health inequalities, rather than individual dentists assuming greater responsibility. Our findings show that dental education may not be accountable to society in the sense that it is not producing graduates who believe that they have an obligation to address the priority oral health concerns of society.

Formative research (i.e. focus groups and key informant interviews) was conducted to understand risk perceptions and identify barriers to participation in a case-control study of environmental exposures and genetic susceptibility as risk factors for multiple sclerosis (MS). Individuals with MS were recruited to participate in a focus group discussion and individual interviews. Participants were asked to review and comment on study materials and process including participation, interview, genetic testing, confidentiality, and questionnaire. A structured discussion guide was used with all participants to ensure uniformity and coverage of all predetermined topics. Participants reported an increased likelihood of participation if they were informed about the study by their neurologist and not a government agency. All participants expressed willingness to provide a blood sample for genotyping but disagreed about the setting for the blood draw (at home or in a lab). Participants were concerned that they would not receive their individual genotyping results. The study protocol and materials were revised based on comments from the focus group participants. Formative research is an under-utilized resource for researchers conducting epidemiologic studies. Even with limited resources, piloting study materials with individuals similar to the proposed study population can provide opportunities to make modifications to effectively meet the needs of participants and promote participation and retention.

To explore nurses' perceptions of their practice environment in acute care hospitals in Sharjah and North Emirates in the United Arab Emirates (UAE). The health of the environment in which registered nurses' work is critical to nursing outcomes. The interest to examine the practice environment extended to the Gulf area which has a complex healthcare system including the UAE. The study used an exploratory descriptive design with a qualitative part using two focus group interviews. The sample size was 450 nurses selected through a random sampling method. A self-administered questionnaire including the Practice Environment Scale of Nursing Work Index (PES-NWI) was used. In addition, semi-structured interviews for two focus groups were done. The results showed that UAE practicing nurses reported favorable perceptions of most aspects of their practice environment. Unfavorable perceptions were only reported for Staffing and Resource Adequacy. The analysis of focus group discussions resulted in different emerged themes such as Lack of Recognition and Career Promotion, and Nurses' Workload due to Paper and Administrative Work. The findings of this study suggest that strategic interventions are needed to secure adequate staff and resources and implement an effective system for evaluation of performance. © 2018 Wiley Periodicals, Inc.

To evaluate urban youths' use of and access to technology and solicit their opinions about using technology with healthcare providers. Urban youth (aged 14-24 years) were invited to participate in focus groups in which a trained focus group facilitator used a survey and a structured guide to elicit responses regarding the foregoing objective. All sessions were audiotaped and transcribed. Emergent themes were determined with the assistance of Atlas TI. Survey data were analyzed in SPSS (SPSS Inc, Chicago, Illinois). Eight focus groups including 82 primarily low-income urban African-American adolescents and young adults (mean age, 18.5 years) were completed. The participants reported fairly high access to and use of technology. However, they expressed some concerns regarding the use of technology with healthcare providers. Many worried about the confidentiality of conversations conducted using technology. Face-to-face meetings with a healthcare provider were preferred by most participants, who felt that the information provided would be better tailored to their individual needs and more credible. Although urban youth were high users of technology, they expressed reservations about using technology with health care providers. When developing new technology communication and information dissemination strategies, it is critical to understand and address these concerns while involving young people in the research and development process.

2013-05-01

Myopia is a significant public health problem in Singapore with estimates that more than 50% of the population is affected by it by the time of adulthood. Childhood obesity is also increasing and has been linked to long-term health problems. Recent studies have found that Singaporean children in Primary 1 spend less than 3 hours a day outdoors which is less than children in other countries. Physical activity has been shown to be protective against obesity and recently, there has been some evidence to suggest that time spent outdoors may reduce the prevalence and severity of myopia. This study aims to explore the barriers and enablers to children in Singapore participating in outdoor activities. Qualitative data, gathered from focus group discussions was thematically analysed against the PRECEDE component of the PRECEDE-PROCEED model which provided a conceptual framework for examining factors relevant to children participating in an outdoor activity intervention. A total of 31 people participated in 4 focus groups held over a 6-month period. This feasibility study was exploratory in nature but provided valuable information concerning barriers and enablers to participation. Data informed the development of a larger study. Results indicated that families preferred structured activities such as orienteering and a choice of weekend attendance days and times.

Should body image programs be inclusive? A focus group study of college students.

PubMed

Ciao, Anna C; Ohls, Olivia C; Pringle, Kevin D

2018-01-01

Most evidence-based body image programs for college students (e.g., the Body Project) are designed for female-only audiences, although body dissatisfaction is not limited to female-identified individuals. Furthermore, programs do not explicitly discuss diversity, although individuals with marginalized gender, racial, and sexual identities may be particularly vulnerable to body image disturbances. Making programs more inclusive may increase their disseminability. This qualitative study examined the feasibility of adapting the Body Project for universal and inclusive use with college students. Participants (N = 36; M age = 21.66 years; 73% female-identified; 20% sexual minority; 23% racial minority) attended one of five semi-structured focus groups to explore the inclusivity of appearance-based cultural norms using adapted Body Project activities and discuss the feasibility of universal and inclusive interventions. Inductive qualitative content analysis with three-rater consensus identified focus group themes. There was consensus that inclusive interventions could have a positive impact (broadening perspectives, normalizing body image concerns, increasing awareness) despite potential barriers (poor diversity representation, vulnerability). There was strong consensus regarding advice for facilitating inclusive interventions (e.g., skilled facilitation, education, increasing diversity). Results suggest that inclusive body image programs are desirable and provide a framework for creating the EVERYbody Project, a program for more universal audiences. © 2017 Wiley Periodicals, Inc.

The purpose of the manuscript is to describe long-term care (LTC) staff perceptions of a music cueing intervention designed to improve staff integration of pressure ulcer (PrU) prevention guidelines regarding consistent and regular movement of LTC residents a minimum of every two hours. The Diffusion of Innovation (DOI) model guided staff interviews about their perceptions of the intervention's characteristics, outcomes, and sustainability. This was a qualitative, observational study of staff perceptions of the PrU prevention intervention conducted in Midwestern U.S. LTC facilities (N = 45 staff members). One focus group was held in each of eight intervention facilities using a semi-structured interview protocol. Transcripts were analyzed using thematic content analysis, and summaries for each category were compared across groups. The a priori codes (observability, trialability, compatibility, relative advantage and complexity) described the innovation characteristics, and the sixth code, sustainability, was identified in the data. Within each code, two themes emerged as a positive or negative response regarding characteristics of the innovation. Moreover, within the sustainability code, a third theme emerged that was labeled "brainstormed ideas", focusing on strategies for improving the innovation. Cueing LTC staff using music offers a sustainable potential to improve PrU prevention practices, to increase resident movement, which can subsequently lead to a reduction in PrUs.

Background: Peer learning is an educational process wherein someone of the same age or level of experience level interacts with other students interested in the same topic. There is limited evidence specifically focusing on the practical use of peer learning in Iran. The aim of this study was to explore nursing students’ experiences of peer learning in clinical practice. Materials and Methods: A qualitative content analysis was conducted. Focus groups were used to find the students’ experiences about peerlearning. Twenty-eight baccalaureate nursing students at Bushehr University of Medical Sciences were selected purposively, and were arranged in four groups of seven students each. The focus group interviews were conducted using a semi-structured interview schedule. All interviews were tape-recorded, transcribed verbatim, and analyzed using conventional content analysis method. Results: The analysis identified four themes: Paradoxical dualism, peer exploitation, first learning efficacy, and socialization practice. Gained advantages and perceived disadvantages created paradoxical dualism, and peer exploitation resulted from peer selection and peer training. Conclusion: Nursing students reported general satisfaction concerning peer learning due to much more in-depth learning with little stress than conventional learning methods. Peer learning is a useful method for nursing students for practicing educational leadership and learning the clinical skills before they get a job. PMID:26097860

Unraveling the meaning of chemical shifts in protein NMR.

Chemical shifts are among the most informative parameters in protein NMR. They provide wealth of information about protein secondary and tertiary structure, protein flexibility, and protein-ligand binding. In this report, we review the progress in interpreting and utilizing protein chemical shifts that has occurred over the past 25years, with a particular focus on the large body of work arising from our group and other Canadian NMR laboratories. More specifically, this review focuses on describing, assessing, and providing some historical context for various chemical shift-based methods to: (1) determine protein secondary and super-secondary structure; (2) derive protein torsion angles; (3) assess protein flexibility; (4) predict residue accessible surface area; (5) refine 3D protein structures; (6) determine 3D protein structures and (7) characterize intrinsically disordered proteins. This review also briefly covers some of the methods that we previously developed to predict chemical shifts from 3D protein structures and/or protein sequence data. It is hoped that this review will help to increase awareness of the considerable utility of NMR chemical shifts in structural biology and facilitate more widespread adoption of chemical-shift based methods by the NMR spectroscopists, structural biologists, protein biophysicists, and biochemists worldwide.

Social Cohesion, Structural Holes, and a Tale of Two Measures

NASA Astrophysics Data System (ADS)

Latora, V.; Nicosia, V.; Panzarasa, P.

2013-05-01

In the social sciences, the debate over the structural foundations of social capital has long vacillated between two positions on the relative benefits associated with two types of social structures: closed structures, rich in third-party relationships, and open structures, rich in structural holes and brokerage opportunities. In this paper, we engage with this debate by focusing on the measures typically used for formalising the two conceptions of social capital: clustering and effective size. We show that these two measures are simply two sides of the same coin, as they can be expressed one in terms of the other through a simple functional relation. Building on this relation, we then attempt to reconcile closed and open structures by proposing a new measure, Simmelian brokerage, that captures opportunities of brokerage between otherwise disconnected cohesive groups of contacts. Implications of our findings for research on social capital and complex networks are discussed.

The social structure of schooling.

PubMed

Dornbusch, S M; Glasgow, K L; Lin, I C

1996-01-01

The term social structure refers to a relatively enduring pattern of social arrangements or interrelations within a particular society, organization, or group. This chapter reviews how the social structure of the larger society and the organizational structure of schools affect the educational process within American schools. The institutional context of schooling is first discussed. The ideology of mass education, social stratification, status attainment, credentialism, and the emphasis on ability differences are considered. The focus then shifts to the organizational structure of schools, beginning with a discussion of the external social context for school organization. Attention is given to professionalism and bureaucracy, institutional forms of organization, decentralized control, and community influences. Finally, the internal structure of school organization is considered: teachers' working conditions, status differences among students, and curriculum tracking. Throughout, the emphasis is on ways in which social structure influences what is taught in school, how it is taught, and what is learned.

CATH version 3.3 (class, architecture, topology, homology) contains 128 688 domains, 2386 homologous superfamilies and 1233 fold groups, and reflects a major focus on classifying structural genomics (SG) structures and transmembrane proteins, both of which are likely to add structural novelty to the database and therefore increase the coverage of protein fold space within CATH. For CATH version 3.4 we have significantly improved the presentation of sequence information and associated functional information for CATH superfamilies. The CATH superfamily pages now reflect both the functional and structural diversity within the superfamily and include structural alignments of close and distant relatives within the superfamily, annotated with functional information and details of conserved residues. A significantly more efficient search function for CATH has been established by implementing the search server Solr (http://lucene.apache.org/solr/). The CATH v3.4 webpages have been built using the Catalyst web framework. PMID:21097779

Background Bullying is a critical public health problem and a screening tool for use in healthcare is needed. Focus groups are a common tool for generating qualitative data when developing an instrument and evidence suggests that technology-enhanced focus groups can be effective in simultaneously engaging participants from diverse settings. Aim To examine the use of technology-enhanced focus groups in generating an item pool to develop a youth-bullying screening tool. Discussion The authors explore methodological and ethical issues related to conducting technology-enhanced focus groups, drawing on their experience in developing a youth-bullying measure. They conducted qualitative focus groups with professionals from the front lines of bullying response and intervention. They describe the experience of conducting technology-enhanced focus group sessions, focusing on the methodological and ethical issues that researchers engaging in similar work may encounter. Challenges associated with this methodology include establishing rapport among participants, privacy concerns and limited non-verbal communication. Conclusion The use of technology-enhanced focus groups can be valuable in obtaining rich data from a wide variety of disciplines and contexts. Organising these focus groups was inexpensive and preferred by the study's participants. Implications for practice Researchers should consider using technology-enhanced focus groups to generate data to develop health-related measurement tools.

Background The prenatal care visit structure has changed little over the past century despite the rapid evolution of technology including Internet and mobile phones. Little is known about how pregnant women engage with technologies and the interface between these tools and medical care, especially for women of lower socioeconomic status. Objective We sought to understand how women use technology during pregnancy through a qualitative study with women enrolled in the Women, Infants, and Children (WIC) program. Methods We recruited pregnant women ages 18 and older who owned a smartphone, at a WIC clinic in central Pennsylvania. The focus group guide included questions about women’s current pregnancy, their sources of information, and whether they used technology for pregnancy-related information. Sessions were audiotaped and transcribed. Three members of the research team independently analyzed each transcript, using a thematic analysis approach. Themes related to the topics discussed were identified, for which there was full agreement. Results Four focus groups were conducted with a total of 17 women. Three major themes emerged as follows. First, the prenatal visit structure is not patient-centered, with the first visit perceived as occurring too late and with too few visits early in pregnancy when women have the most questions for their prenatal care providers. Unfortunately, the educational materials women received during prenatal care were viewed as unhelpful. Second, women turn to technology (eg, Google, smartphone applications) to fill their knowledge gaps. Turning to technology was viewed to be a generational approach. Finally, women reported that technology, although frequently used, has limitations. Conclusions The results of this qualitative research suggest that the current prenatal care visit structure is not patient-centered in that it does not allow women to seek advice when they want it most. A generational shift seems to have occurred, resulting in pregnant women in our study turning to the Internet and smartphones to fill this gap, which requires significant skills to navigate for useful information. Future steps may include developing interventions to help health care providers assist patients early in pregnancy to seek the information they want and to become better consumers of Internet-based pregnancy resources.

Understanding How Overweight and Obese Emerging Adults Make Lifestyle Choices.

PubMed

Cha, EunSeok; Crowe, James M; Braxter, Betty J; Jennings, Bonnie Mowinski

To better understand health-related decision making among overweight and obese emerging adults. A cross-sectional design was used in the parent study involving overweight and obese emerging adults, ages 18-29 years. The goal of the parent study was to screen participants' diabetes risk and identify characteristics of emerging adults with prediabetes (N=107). A sub-sample of respondents (n=34) from the parent study were invited to participate in focus group interviews depending on whether they had prediabetes (three groups) or they did not have prediabetes (four groups). Each focus group interview lasted 90-120 minutes following a semi-structured interview guide. Conventional content analysis was used in the data analysis. Because of the similarities between participants with and without prediabetes, the findings were synthesized and reported in the aggregate. Moreover, during the analysis, the authors decided that rational choice theory provided a useful organizing structure for presenting the data. Emerging adults' behavioral decisions were rational reactions to their personal competence, perception of health, environment, and availability of resources to handle problems. Calculation of trade-offs and estimations of resource availability were often used when making decisions. Emerging adults choose unhealthy behaviors due to inaccurate information and insufficient competence to practice healthy lifestyles rather than because of laziness or being irrational. Behavioral interventions for emerging adults need to help them develop skills to enhance health literacy and problem solving, thereby enhancing their awareness of available resources and decreasing the perceived cost of making healthy choices.

South Asians constitute the single largest ethnic minority group in the United Kingdom, yet little is known about their perspectives on, and experiences of, end-of-life care. To explore beliefs, attitudes and expectations expressed by older South Asians living in East London about dying at home. A qualitative study using focus groups and semi-structured interviews. Data were analysed using a constructivist grounded theory approach. Five focus groups and 29 in-depth semi-structured interviews were conducted with a total of 55 older adults (24 men and 31 women) aged between 52 and 78 years. Participants from six South Asian ethnic groups were recruited via 11 local community organisations. Two key themes were identified. The theme of 'reconsidering the homeland' draws on the notion of 'diaspora' to help understand why for many participants, the physical place of death was perceived as less important than the opportunity to carry out cultural and religious practices surrounding death. The second theme 'home as a haven' describes participants' accounts of how their home is a place in which it is possible to perform various cultural and religious rituals. Cultural and religious practices were often seen as essential to achieving a peaceful death and honouring religious and filial duties. Older people of South Asian ethnicity living in East London perceive home as more than a physical location for dying relatives. They make efforts to adhere, and also adapt, to important social and cultural values relating to death and dying as part of the wider challenge of living in an emigrant society.

Disease management remains a challenge for many people living with HIV (PLWH). Digital health interventions (DHIs) may assist with overcoming these challenges and reducing burdens on clinical staff; however, there is limited data regarding methods to improve uptake and acceptability of DHIs among PLWH. This qualitative study aimed to assess patient and provider perspectives on the use of DHIs and strategies to promote uptake among PLWH. Eight focus groups with patients (k = 5 groups; n = 24) and providers (k = 3 groups; n = 12) were conducted May through October of 2014. Focus groups (~90 min) followed a semi-structured interview guide. Data were analyzed using thematic analysis on three main themes: (a) perspectives towards the adoption and use of DHIs for HIV management; (b) perceptions of barriers and facilitators to patient usage; and (c) preferences regarding content, structure, and delivery. Analyses highlighted barriers and facilitators to DHI adoption. Patients and providers agreed that DHIs feel "impersonal" and "lack empathy," may be more effective for certain subpopulations, should be administered in the clinic setting, and should use multimodal delivery methods. Emergent themes among the providers included development of DHIs for providers as the target market and the need for culturally adapted DHIs for patient subpopulations. DHIs have potential to improve HIV management and health outcomes. DHIs should be developed in conjunction with anticipated consumers, including patients, providers, and other key stakeholders. DHIs tailored for specific HIV subpopulations are needed. Future studies should evaluate dissemination methods and marketing strategies to promote uptake.

In this paper, we present a high-quality superlens to focus acoustic waves using a periodically perforated metallic structure which is made of zinc and immersed in water. By changing a geometrical parameter gradually, a kind of gradient-index phononic crystal lens is designed to attain the mirage effects. The acoustic waves can propagate along an arc-shaped trajectory which is precisely controlled by the angle and frequency of the incident waves. The negative refraction imaging effect depends delicately on the transmittance of the solid structure. The acoustic impedance matching between the solid and the liquid proposed in this article, which is determined by the effective density and group velocity of the unit-cell, is significant for overcoming the inefficiency problem of acoustic devices. This study focuses on how to obtain the high transmittance imaging and mirage effects based on the adequate material selection and geometrical design.

This article provides an overview of a growing body of international research focusing on the structural and environmental factors that shape the spread of the HIV/AIDS epidemic, and create barriers and facilitators in relation to HIV-prevention programs. OVERVIEW OF STRUCTURAL-FACTORS LITERATURE: Most of the research on structural and environmental factors can be grouped into a small number of analytically distinct but interconnected categories: economic (under)development and poverty; mobility, including migration, seasonal work, and social disruption due to war and political instability; and gender inequalities. An additional focus in research on structural and environmental factors has been on the effects of particular governmental and intergovernmental policies in increasing or diminishing HIV vulnerability and transmission. A smaller subset of the research on structural factors describes and/or evaluates specific interventions in detail. Approaches that have received significant attention include targeted interventions developed for heterosexual women, female commercial sex workers, male truck drivers, and men who have sex with men. The structural and environmental factors literature offers important insights and reveals a number of productive intervention strategies that might be explored in both resource-rich and -poor settings. However, new methodologies are required to document and evaluate the effects of the structural interventions, which by their very nature involve large-scale elements that cannot be easily controlled by experimental or quasi-experimental research designs. Innovative, interdisciplinary approaches are needed that can move beyond the limited successes of traditional behavioral interventions and explicitly attempt to achieve broader social and structural change.

What are the views and perceptions of people with chronic obstructive pulmonary disease (COPD) regarding maintaining an active lifestyle following a course of pulmonary rehabilitation? Qualitative study of two focus groups using a grounded theory approach. Sixteen people with COPD who had completed a course of pulmonary rehabilitation. Data from focus groups concurred and five main themes emerged: value of pulmonary rehabilitation, ongoing exercise, professional support, peer social support, and health status. Pulmonary rehabilitation was seen as facilitating greater participation in everyday activity by improving physical ability and confidence to manage breathlessness, and reducing fear about exertional activity. An exercise routine following rehabilitation was perceived as essential for maintaining activity, with participants voicing a need for ongoing, structured and supervised sessions to maintain new found abilities. The exercise facility presented a possible barrier to attendance due to its potential to provoke feelings of embarrassment or intimidation. Professional and peer support were identified as key elements; participants expressed a desire to exercise within a peer group combined with an opportunity for social interaction. Health status relating to COPD symptoms was also identified as negatively impacting on physical activity participation. Confidence or self-efficacy for physical activity emerged as a prominent factor within main themes. The opportunity for structured, ongoing exercise with peer and professional support, in a suitable venue, is perceived as important to people with COPD in facilitating a physically active lifestyle following pulmonary rehabilitation. This desire for such opportunities may be related to individuals' self-efficacy towards physical activity. Copyright © 2012 Australian Physiotherapy Association. Published by .. All rights reserved.

BACKGROUND Ethnic diversity among physicians may be linked to improved access and quality of care for minorities. Academic medical institutions are challenged to increase representation of ethnic minorities among health professionals. OBJECTIVES To explore the perceptions of physician faculty regarding the following: (1) the institution's cultural diversity climate and (2) facilitators and barriers to success and professional satisfaction in academic medicine within this context. DESIGN Qualitative study using focus groups and semi-structured interviews. PARTICIPANTS Nontenured physicians in the tenure track at the Johns Hopkins University School of Medicine. APPROACH Focus groups and interviews were audio-taped, transcribed verbatim, and reviewed for thematic content in a 3-stage independent review/adjudication process. RESULTS Study participants included 29 faculty representing 9 clinical departments, 4 career tracks, and 4 ethnic groups. In defining cultural diversity, faculty noted visible (race/ethnicity, foreign-born status, gender) and invisible (religion, sexual orientation) dimensions. They believe visible dimensions provoke bias and cumulative advantages or disadvantages in the workplace. Minority and foreign-born faculty report ethnicity-based disparities in recruitment and subtle manifestations of bias in the promotion process. Minority and majority faculty agree that ethnic differences in prior educational opportunities lead to disparities in exposure to career options, and qualifications for and subsequent recruitment to training programs and faculty positions. Minority faculty also describe structural barriers (poor retention efforts, lack of mentorship) that hinder their success and professional satisfaction after recruitment. To effectively manage the diversity climate, our faculty recommended 4 strategies for improving the psychological climate and structural diversity of the institution. CONCLUSIONS Soliciting input from faculty provides tangible ideas regarding interventions to improve an institution's diversity climate. PMID:16050848

Current and future ground and space based missions are designed to not only detect, but map out with increasing precision, details of the universe in its infancy to the present-day. As a result we are faced with the challenge of analyzing and interpreting observations from a wide variety of instruments to form a coherent view of the universe. Finding solutions to a broad range of challenging inference problems in cosmology is one of the goals of the “Statistics, Computation, and Modeling in Cosmology” workings groups, formed as part of the year long program on ‘Statistical, Mathematical, and Computational Methods for Astronomy’, hosted by the Statistical and Applied Mathematical Sciences Institute (SAMSI), a National Science Foundation funded institute. Two application areas have emerged for focused development in the cosmology working group involving advanced algorithmic implementations of exact Bayesian inference for the Cosmic Microwave Background, and statistical modeling of galaxy formation. The former includes study and development of advanced Markov Chain Monte Carlo algorithms designed to confront challenging inference problems including inference for spatial Gaussian random fields in the presence of sources of galactic emission (an example of a source separation problem). Extending these methods to future redshift survey data probing the nonlinear regime of large scale structure formation is also included in the working group activities. In addition, the working group is also focused on the study of ‘Galacticus’, a galaxy formation model applied to dark matter-only cosmological N-body simulations operating on time-dependent halo merger trees. The working group is interested in calibrating the Galacticus model to match statistics of galaxy survey observations; specifically stellar mass functions, luminosity functions, and color-color diagrams. The group will use subsampling approaches and fractional factorial designs to statistically and computationally efficiently explore the Galacticus parameter space. The group will also use the Galacticus simulations to study the relationship between the topological and physical structure of the halo merger trees and the properties of the resulting galaxies.

This research evaluates the properties of a measure of culturally linked values of Mexican Americans in early adolescence and adulthood. The items measure were derived from qualitative data provided by focus groups in which Mexican Americans’ (adolescents, mothers and fathers) perceptions of key values were discussed. The focus groups and a preliminary item refinement resulted in the fifty-item Mexican American Cultural Values Scales (identical for adolescents and adults) that includes nine value subscales. Analyses of data from two large previously published studies sampling Mexican American adolescents, mothers, and fathers provided evidence of the expected two correlated higher order factor structures, reliability, and construct validity of the subscales of the Mexican American Cultural Values Scales as indicators of values that are frequently associated with Mexican/Mexican American culture. The utility of this measure for use in longitudinal research, and in resolving some important theoretical questions regarding dual cultural adaptation, are discussed. PMID:20644653

The purpose of this paper is to raise an argument that inclusiveness will lessen the pain of losing a parent among adolescents orphaned by AIDS and as a result, prevent future mental health problems that may occur because of inappropriate grieving and maladaptive coping strategies. Participation of adolescents orphaned by AIDS in decisions pertaining to their parents' illnesses and funeral arrangements, for example, may shorten the grieving process and allow for closure. The paper draws data from focus group discussions that were held with 15 adolescents orphaned by AIDS in urban South Africa. The focus group discussions that were structured around four themes: grieving patterns; coping strategies; experience with loss; and expectations. The results of the study demonstrate inclusiveness as an overarching factor in the healing process. The concept is thus a strong recommendation for mental health practice and further study. © 2011 Blackwell Publishing.

Experience can affect human gray matter volume. The behavioral correlates of individual differences in such brain changes are not well understood. In a group of Swedish individuals studying Italian as a foreign language, we investigated associations among time spent studying, acquired vocabulary, baseline performance on memory tasks, and gray matter changes. As a way of studying episodic memory training, the language learning focused on acquiring foreign vocabulary and lasted for 10weeks. T1-weighted structural magnetic resonance imaging and cognitive testing were performed before and after the studies. Learning behavior was monitored via participants' use of a smartphone application dedicated to the study of vocabulary. A whole-brain analysis showed larger changes in gray matter structure of the right hippocampus in the experimental group (N=33) compared to an active control group (N=23). A first path analyses revealed that time spent studying rather than acquired knowledge significantly predicted change in gray matter structure. However, this association was not significant when adding performance on baseline memory measures into the model, instead only the participants' performance on a short-term memory task with highly similar distractors predicted the change. This measure may tap similar individual difference factors as those involved in gray matter plasticity of the hippocampus. Copyright © 2015 Elsevier Inc. All rights reserved.

To investigate the influence of the type of carbonyl group of the sugar on the structural changes of proteins during glycation, an exhaustive structural characterization of glycated beta-lactoglobulin with galactose (aldose) and tagatose (ketose) has been carried out. Conjugates were prepared via Maillard reaction at 40 and 50 degrees C, pH 7, and a w = 0.44. The progress of the Maillard reaction was followed by indirect formation of Amadori and Heyns compounds, advanced glycation end products, and brown polymers. The structural characterization of glycoconjugates was conducted by using a number of analytical techniques such as RP-HPLC, isoelectric focusing, MALDI-ToF, SDS-PAGE, size exclusion chromatography, and spectrofluorimetry (tryptophan fluorescence). In addition, the surface hydrophobicity of the beta-lactoglobulin glycoconjugates was also assessed. The results showed a higher reactivity of galactose than tagatose to form the glycoconjugates, probably due to the higher electrophilicity of the aldehyde group. At 40 degrees C, more aggregation was produced when beta-lactoglobulin was conjugated with tagatose as compared to galactose. However, at 50 degrees C hardly any difference was observed in the aggregation produced by galactose and tagatose. These results afford more insight into the importance of the functional group of the carbohydrate moiety during the formation of protein-carbohydrate conjugates via Maillard reaction.

Although learning through a computer interface has become increasingly common, little is known about how to best structure video-recorded lectures to optimize learning. In 2 experiments, we examine changes in focused attention and the ability for students to integrate knowledge learned during a 40-min video-recorded lecture. In Experiment 1, we demonstrate that interpolating a lecture with memory tests (tested group), compared to studying the lecture material for the same amount of time (restudy group), improves overall learning and boosts integration of related information learned both within individual lecture segments and across the entire lecture. Although mind wandering rates between the tested and restudy groups did not differ, mind wandering was more detrimental for final test performance in the restudy group than in the tested group. In Experiment 2, we replicate the findings of Experiment 1, and additionally show that interpolated tests influence the types of thoughts that participants report during the lecture. While the tested group reported more lecture-related thoughts, the restudy group reported more lecture-unrelated thoughts; furthermore, lecture-related thoughts were positively related to final test performance, whereas lecture-unrelated thoughts were negatively related to final test performance. Implications for the use of interpolated testing in video-recorded lectures are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Data on the synthesis and physicochemical studies of salts of mono- or dibasic unsaturated carboxylic acids and unsaturated metal oxo-carboxylates are generalised and described systematically. The structures and properties of the COO group in various compounds and characteristic features of the structures of carboxylate complexes are analysed. The main routes and kinetics of polymerisation transformations of unsaturated metal carboxylates are considered. The attention is focused on the effect of the metal ion on the monomer reactivity and the polymer morphology and structure. The possibility of stereochemical control of radical polymerisation of unsaturated metal carboxylates is demonstrated. The electronic, magnetic, optical, absorption and thermal properties of metal (co)polymers and nanocomposites and their main applications are considered.

Metamaterial acoustic lenses are acoustic devices based on phononic crystal structures that take advantage of negative or near-zero indices of refraction. These unique properties arise due to either the antiparallel direction of the phase and group velocity or strongly anisotropic dispersion characteristics, usually above the first transmission band. In this study, we utilize an FDTD program to examine two phononic lenses that utilize anisotropic effects available in their second band to collimate and focus acoustic waves from a plane-wave source with a k00 wavevector. The phononic crystals consist of stainless steel rods arranged in a square lattice with water as the ambient material. Results show collimation and focusing in the second band for select frequencies, fc ± 0.005𝑓𝑐.

While evidence supports community health worker (CHW) capacity to improve maternal and newborn health in less-resourced countries, key implementation gaps remain. Tools for assessing CHW performance and evidence on what programmatic components affect performance are lacking. This study developed and tested a qualitative evaluative framework and tool to assess CHW team performance in a district program in rural Uganda. A new assessment framework was developed to collect and analyze qualitative evidence based on CHW perspectives on seven program components associated with effectiveness (selection; training; community embeddedness; peer support; supportive supervision; relationship with other healthcare workers; retention and incentive structures). Focus groups were conducted with four high/medium-performing CHW teams and four low-performing CHW teams selected through random, stratified sampling. Content analysis involved organizing focus group transcripts according to the seven program effectiveness components, and assigning scores to each component per focus group. Four components, 'supportive supervision', 'good relationships with other healthcare workers', 'peer support', and 'retention and incentive structures' received the lowest overall scores. Variances in scores between 'high'/'medium'- and 'low'-performing CHW teams were largest for 'supportive supervision' and 'good relationships with other healthcare workers.' Our analysis suggests that in the Bushenyi intervention context, CHW team performance is highly correlated with the quality of supervision and relationships with other healthcare workers. CHWs identified key performance-related issues of absentee supervisors, referral system challenges, and lack of engagement/respect by health workers. Other less-correlated program components warrant further study and may have been impacted by relatively consistent program implementation within our limited study area. Applying process-oriented measurement tools are needed to better understand CHW performance-related factors and build a supportive environment for CHW program effectiveness and sustainability. Findings from a qualitative, multi-component tool developed and applied in this study suggest that factors related to (1) supportive supervision and (2) relationships with other healthcare workers may be strongly associated with variances in performance outcomes within a program. Careful consideration of supervisory structure and health worker orientation during program implementation are among strategies proposed to increase CHW performance.

A Randomised Controlled Trial to Reduce Sedentary Time in Young Adults at Risk of Type 2 Diabetes Mellitus: Project STAND (Sedentary Time ANd Diabetes).

Type 2 diabetes mellitus (T2DM), a serious and prevalent chronic disease, is traditionally associated with older age. However, due to the rising rates of obesity and sedentary lifestyles, it is increasingly being diagnosed in the younger population. Sedentary (sitting) behaviour has been shown to be associated with greater risk of cardio-metabolic health outcomes, including T2DM. Little is known about effective interventions to reduce sedentary behaviour in younger adults at risk of T2DM. We aimed to investigate, through a randomised controlled trial (RCT) design, whether a group-based structured education workshop focused on sitting reduction, with self-monitoring, reduced sitting time. Adults aged 18-40 years who were either overweight (with an additional risk factor for T2DM) or obese were recruited for the Sedentary Time ANd Diabetes (STAND) RCT. The intervention programme comprised of a 3-hour group-based structured education workshop, use of a self-monitoring tool, and follow-up motivational phone call. Data were collected at three time points: baseline, 3 and 12 months after baseline. The primary outcome measure was accelerometer-assessed sedentary behaviour after 12 months. Secondary outcomes included other objective (activPAL) and self-reported measures of sedentary behaviour and physical activity, and biochemical, anthropometric, and psycho-social variables. 187 individuals (69% female; mean age 33 years; mean BMI 35 kg/m2) were randomised to intervention and control groups. 12 month data, when analysed using intention-to-treat analysis (ITT) and per-protocol analyses, showed no significant difference in the primary outcome variable, nor in the majority of the secondary outcome measures. A structured education intervention designed to reduce sitting in young adults at risk of T2DM was not successful in changing behaviour at 12 months. Lack of change may be due to the brief nature of such an intervention and lack of focus on environmental change. Moreover, some participants reported a focus on physical activity rather than reductions in sitting per se. The habitual nature of sedentary behaviour means that behaviour change is challenging.
