The GRADE-CERQual ('Confidence in the Evidence from Reviews of Qualitative research') approach provides guidance for assessing how much confidence to place in findings from systematic reviews of qualitative research (or qualitative evidence syntheses). The approach has been developed to support the use of findings from qualitative evidence syntheses in decision-making, including guideline development and policy formulation. Confidence in the evidence from qualitative evidence syntheses is an assessment of the extent to which a review finding is a reasonable representation of the phenomenon of interest. CERQual provides a systematic and transparent framework for assessing confidence in individual review findings, based on consideration of four components: (1) methodological limitations, (2) coherence, (3) adequacy of data, and (4) relevance. A fifth component, dissemination (or publication) bias, may also be important and is being explored. As with the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach for effectiveness evidence, CERQual suggests summarising evidence in succinct, transparent, and informative Summary of Qualitative Findings tables. These tables are designed to communicate the review findings and the CERQual assessment of confidence in each finding. This article is the first of a seven-part series providing guidance on how to apply the CERQual approach. In this paper, we describe the rationale and conceptual basis for CERQual, the aims of the approach, how the approach was developed, and its main components. We also outline the purpose and structure of this series and discuss the growing role for qualitative evidence in decision-making. Papers 3, 4, 5, 6, and 7 in this series discuss each CERQual component, including the rationale for including the component in the approach, how the component is conceptualised, and how it should be assessed. Paper 2 discusses how to make an overall assessment of confidence in a review finding and how to create a Summary of Qualitative Findings table. The series is intended primarily for those undertaking qualitative evidence syntheses or using their findings in decision-making processes but is also relevant to guideline development agencies, primary qualitative researchers, and implementation scientists and practitioners.

Incidental genetic findings in randomized clinical trials: recommendations from the Genomics and Randomized Trials Network (GARNET)

PubMed Central

2013-01-01

Recommendations and guidance on how to handle the return of genetic results to patients have offered limited insight into how to approach incidental genetic findings in the context of clinical trials. This paper provides the Genomics and Randomized Trials Network (GARNET) recommendations on incidental genetic findings in the context of clinical trials, and discusses the ethical and practical issues considered in formulating our recommendations. There are arguments in support of as well as against returning incidental genetic findings in clinical trials. For instance, reporting incidental findings in clinical trials may improve the investigator-participant relationship and the satisfaction of participation, but it may also blur the line between clinical care and research. The issues of whether and how to return incidental genetic findings, including the costs of doing so, should be considered when developing clinical trial protocols. Once decided, plans related to sharing individual results from the aim(s) of the trial, as well as incidental findings, should be discussed explicitly in the consent form. Institutional Review Boards (IRBs) and other study-specific governing bodies should be part of the decision as to if, when, and how to return incidental findings, including when plans in this regard are being reconsidered.

Intramammary Findings on CT of the Chest – a Review of Normal Anatomy and Possible Findings

PubMed Central

Gossner, Johannes

2016-01-01

Summary Computed tomography (CT) is a frequently performed examination in women of all ages. In all thoracic CT examinations of the chest at least parts of the breasts are included. Therefore incidental breast pathology may be observed. It has been suggested that one out of 250 women undergoing chest CT will show a malignant incidental breast lesion. Given the high number of performed chest CT examinations, this contributes to a significant number of malignancies. In this review, after a brief discussion of the value of computed tomography in breast imaging, normal and pathologic findings are discussed to create awareness of this potential “black box” on chest CT.

Access to primary care from the perspective of Aboriginal patients at an urban emergency department.

PubMed

Browne, Annette J; Smye, Victoria L; Rodney, Patricia; Tang, Sannie Y; Mussell, Bill; O'Neil, John

2011-03-01

In this article, we discuss findings from an ethnographic study in which we explored experiences of access to primary care services from the perspective of Aboriginal people seeking care at an emergency department (ED) located in a large Canadian city. Data were collected over 20 months of immersion in the ED, and included participant observation and in-depth interviews with 44 patients triaged as stable and nonurgent, most of whom were living in poverty and residing in the inner city. Three themes in the findings are discussed: (a) anticipating providers' assumptions; (b) seeking help for chronic pain; and (c) use of the ED as a reflection of social suffering. Implications of these findings are discussed in relation to the role of the ED as well as the broader primary care sector in responding to the needs of patients affected by poverty, racialization, and other forms of disadvantage.

Online discussions with pregnant and parenting adolescents: perspectives and possibilities.

PubMed

Valaitis, Ruta K; Sword, Wendy A

2005-10-01

The Internet is an innovative strategy to increase public participation. It is important to include pregnant and parenting teens' perspectives when planning programs to meet their needs. This qualitative study explored online discussions as a strategy to enhance participation by this population. Findings showed that online communication was preferred over face-to-face group discussions. Being anonymous online encouraged open and honest feedback. Participants experienced various forms of social support, however, there was an overall lack of teen involvement online. Strategies to engage adolescents in online discussions and reduce barriers are discussed. Strategies included the use of teen moderators, home computer access, technical support, and engagement in naturally flowing online discussions to meet social support needs. Blending researchers' with teens' needs for social support in an online environment is encouraged. With careful planning and design, online communications can result in mutual benefits for researchers, service providers, and pregnant and parenting adolescents.

Pharmaceutical drugs chatter on Online Social Networks.

PubMed

Wiley, Matthew T; Jin, Canghong; Hristidis, Vagelis; Esterling, Kevin M

2014-06-01

The ubiquity of Online Social Networks (OSNs) is creating new sources for healthcare information, particularly in the context of pharmaceutical drugs. We aimed to examine the impact of a given OSN's characteristics on the content of pharmaceutical drug discussions from that OSN. We compared the effect of four distinguishing characteristics from ten different OSNs on the content of their pharmaceutical drug discussions: (1) General versus Health OSN; (2) OSN moderation; (3) OSN registration requirements; and (4) OSNs with a question and answer format. The effects of these characteristics were measured both quantitatively and qualitatively. Our results show that an OSN's characteristics indeed affect the content of its discussions. Based on their information needs, healthcare providers may use our findings to pick the right OSNs or to advise patients regarding their needs. Our results may also guide the creation of new and more effective domain-specific health OSNs. Further, future researchers of online healthcare content in OSNs may find our results informative while choosing OSNs as data sources. We reported several findings about the impact of OSN characteristics on the content of pharmaceutical drug discussion, and synthesized these findings into actionable items for both healthcare providers and future researchers of healthcare discussions on OSNs. Future research on the impact of OSN characteristics could include user demographics, quality and safety of information, and efficacy of OSN usage. Copyright © 2014 Elsevier Inc.

2015-10-01

To identify the specific needs, preferences and expectations of the stakeholders impacted by returning neuroimaging incidental findings to research participants. Six key stakeholder groups were identified to participate in focus group discussions at our active neuroimaging research facility: Participants, Parents of child participants, Investigators, Institutional Review Board (IRB) Members, Physicians and Community Members. A total of 151 subjects attended these discussions. Transcripts were analysed using principles of Grounded Theory and group consensus coding. A series of similar and divergent themes were identified across our subject groups. Similarities included beliefs that it is ethical for researchers to disclose incidental findings as it grants certain health and emotional benefits to participants. All stakeholders also recognised the potential psychological and financial risks to disclosure. Divergent perspectives elucidated consistent differences between our 'Participant' subjects (Participants, Parents, Community Members) and our 'Professional' subjects (IRB Members, Investigators and Physicians). Key differences included (1) what results should be reported, (2) participants' autonomous right to research information and (3) the perception of the risk-benefit ratio in managing results. Understanding the perceived impact on all stakeholders involved in the process of disclosing incidental findings is necessary to determine appropriate research management policy. Our data further demonstrate the challenge of this task as different stakeholders evaluate the balance between risk and benefit related to their unique positions in this process. These findings offer some of the first qualitative insight into the expectations of the diverse stakeholders affected by incidental finding disclosure. Published by the BMJ Publishing Group Limited.

Is There a Role for Social Networking Sites in Education?

NASA Astrophysics Data System (ADS)

Santos, Ieda M.; Hammond, Michael; Durli, Zenilde; Chou, Shiao-Yuh

Social networking sites such as Facebook and MySpace have become popular among millions of users including students of all ages. There are ongoing discussions over the potential of these sites to support teaching and learning, particularly to complement traditional or online classroom activities. This paper explores whether social networking have a place in teaching and learning by investigating how students use these sites and whether they find opportunities to discuss study related activities with their peers. Two small scale studies were carried out in a face-to-face undergraduate course in Singapore and students enrolled in a face-to-face Master’s programme in Brazil. Data were collected using surveys and interviews; findings were mixed. Many of the Brazilian students used social networking sites to both socialize and discuss their studies while the Singaporean students used such sites for social interactions only. The paper discusses these differences and offers suggestions for further research.

Promoting resilience among displaced adolescent girls in northern Pakistan may buffer against developmental risks such as violence exposure and associated longer-term consequences for physical and mental well-being. However, girls' access to such programming may be limited by social norms restricting movement. A mixed-method evaluation examined change over time, feasibility, and acceptability of the COMPASS program in three districts of Khyber-Pakhtunkhwa province through a single-group within-participant pretest-posttest of adolescent girls aged 12-19 enrolled in the intervention (n = 78), and qualitative in-depth interviews with girls following posttest completion (n = 15). Primary outcomes included improvements in movement, safety, and comfort discussing life skills topics with caregivers, operationalized quantitatively as number of places visited in the previous month, number of spaces that girls felt safe visiting, and comfort discussing puberty, education, working outside the home, and marriage, respectively. Secondary outcomes included psychosocial well-being, gendered rites of passage, social support networks, perceptions of support for survivors of violence, and knowledge of services. Quantitative pretest-posttest findings included significant improvements in movement, psychosocial well-being, and some improvements in social support, knowledge of services, and gendered rites of passage; findings on safety and comfort discussing life skills topics were not significant. Qualitative findings illuminated themes related to definitions of safety and freedom of movement, perceptions and acceptability of program content, perceptions of social support, and perceptions of blame and support and knowledge of services in response to violence. Taken together, findings illustrate positive impacts of life skills programming, and the need for societal changes on gender norms to improve girls' safety in public spaces and access to resources.

Carbon Nanotubes for Supercapacitor

PubMed Central

2010-01-01

As an electrical energy storage device, supercapacitor finds attractive applications in consumer electronic products and alternative power source due to its higher energy density, fast discharge/charge time, low level of heating, safety, long-term operation stability, and no disposable parts. This work reviews the recent development of supercapacitor based on carbon nanotubes (CNTs) and their composites. The purpose is to give a comprehensive understanding of the advantages and disadvantages of carbon nanotubes-related supercapacitor materials and to find ways for the improvement in the performance of supercapacitor. We first discussed the effects of physical and chemical properties of pure carbon nanotubes, including size, purity, defect, shape, functionalization, and annealing, on the supercapacitance. The composites, including CNTs/oxide and CNTs/polymer, were further discussed to enhance the supercapacitance and keep the stability of the supercapacitor by optimally engineering the composition, particle size, and coverage.

More than 500,000 new medical articles are published every year and available time to keep updated is scarcer every day. Nowadays, the task of selecting useful, consistent, and relevant information for clinicians is a priority in many major medical journals. This review has the aim of gathering the results of the most important findings in clinical medicine in the last few years. It is focused on results from randomized clinical trials and well-designed observational research. Findings were included preferentially if they showed solid results, and we avoided as much as possible including only preliminary data, or results that included only non-clinical outcomes. Some of the most relevant findings reported here include the significant benefit of statins in patients with coronary artery disease even with mean cholesterol level. It also provides a substantial review of the most significant trials assessing the effectiveness of IIb/IIIa receptor blockers. In gastroenterology many advances have been made in the H. pylori eradication, and the finding that the cure of H. pylori infection may be followed by gastroesophageal reflux disease. Some new antivirals have shown encouraging results in patients with chronic hepatitis. In the infectious disease arena, the late breaking trials in anti-retroviral disease are discussed, as well as the new trends regarding antibiotic resistance. This review approaches also the role of leukotriene modifiers in the treatment of asthma and discusses the benefit of using methylprednisolone in patients with adult respiratory distress syndrome, among many other advances in internal medicine.

King, Lindsey; Quinn, Gwendolyn P; Vadaparampil, Susan T; Gwede, Clement K; Miree, Cheryl A; Wilson, Crystal; Clayton, Heather; Perrin, Karen

2008-06-01

Infertility is a common result of cancer treatment; however, opportunities exist for patients to preserve fertility prior to treatment. Recent evidence suggests that healthcare providers, including nurses, do not consistently discuss fertility preservation (FP) with patients. This qualitative, cross-sectional pilot study used a focus group and in-depth interviews to explore knowledge, attitudes, and practice behaviors related to nurses' discussion of FP with patients with cancer. Results indicate that only half of the nurses discuss FP methods with patients, even though most believe that having discussions with patients about fertility is part of their role. Factors associated with the discussion of FP among nurses included (a) knowledge (FP procedures, fertility institutes and clinics, resources for patients, and practice guidelines), (b) attitudes (difficulty finding facilities, time constraints, role, comfort level, ethical issues, financial considerations, and patient characteristics), and (c) behaviors (patient initiation, physician behaviors, patient characteristics, and timing). Discussion should be stimulated among nurses about the role of nurses in the FP discussion, and educational interventions and practice guidelines should be developed that are aimed at oncology nurses to help facilitate discussions with patients.

Space power technology 21: Photovoltaics

NASA Astrophysics Data System (ADS)

Wise, Joseph

1989-04-01

The Space Power needs for the 21st Century and the program in photovoltaics needed to achieve it are discussed. Workshops were conducted in eight different power disciplines involving industry and other government agencies. The Photovoltaics Workshop was conducted at Aerospace Corporation in June 1987. The major findings and recommended program from this workshop are discussed. The major finding is that a survivable solar power capability is needed in photovoltaics for critical Department of Defense missions including Air Force and Strategic Defense Initiative. The tasks needed to realize this capability are described in technical, not financial, terms. The second finding is the need for lightweight, moderately survivable planar solar arrays. High efficiency thin III-V solar cells can meet some of these requirements. Higher efficiency, longer life solar cells are needed for application to both future planar and concentrator arrays with usable life up to 10 years. Increasing threats are also anticipated and means for avoiding prolonged exposure, retraction, maneuvering and autonomous operation are discussed.

Wandering in the dark: women's experiences with depression.

PubMed

Schreiber, R

2001-01-01

In North America, rates of depression for women are consistently higher than for men. This phenomenon is poorly understood; nonetheless, the use of grounded theory to investigate women's experiences with depression, treatment, and recovery revealed some unexpected findings. In this article I discuss findings resulting from examination of data from three grounded theory studies of women and depression. In all, data were collected through participant observation and more than 70 interviews and the study sample included participants varying in race, marital status, cultural background, and sexual orientation between 18 to 69 years of age, and included both mothers and nonmothers. Findings included the presence in women of an internal dialogue, reinforcing the philosophical origins of the method in symbolic interactionism; oppression and marginalization of women's experiences; the impact of violence in women's lives; the roles of treatment and learning; and the hope of recovery. I will finish by identifying some questions arising from the findings.

Tanning increases dramatically through the teenage years, but the family context of this health risk behavior is relatively unstudied. We conducted videotaped conversations between teenage girls (10th and 11th grade) and their mothers. We developed a coding system for discussion content and highlight findings including inadequate knowledge concerning the harms of tanning and positive views of outdoor tanning over indoor tanning, yet agreement that all tans are attractive. Many teens believed that indoor tanning is sometimes necessary to achieve the tanned look. These findings can usefully guide intervention development regarding the harms of all tanning, rather than indoor or outdoor tanning specifically. © The Author(s) 2014.

Integrating molecular and morphological approaches for characterizing parasite cryptic species: implications for parasitology.

PubMed

Nadler, Steven A; DE León, Gerardo Pérez-Ponce

2011-11-01

Herein we review theoretical and methodological considerations important for finding and delimiting cryptic species of parasites (species that are difficult to recognize using traditional systematic methods). Applications of molecular data in empirical investigations of cryptic species are discussed from an historical perspective, and we evaluate advantages and disadvantages of approaches that have been used to date. Developments concerning the theory and practice of species delimitation are emphasized because theory is critical to interpretation of data. The advantages and disadvantages of different molecular methodologies, including the number and kind of loci, are discussed relative to tree-based approaches for detecting and delimiting cryptic species. We conclude by discussing some implications that cryptic species have for research programmes in parasitology, emphasizing that careful attention to the theory and operational practices involved in finding, delimiting, and describing new species (including cryptic species) is essential, not only for fully characterizing parasite biodiversity and broader aspects of comparative biology such as systematics, evolution, ecology and biogeography, but to applied research efforts that strive to improve development and understanding of epidemiology, diagnostics, control and potential eradication of parasitic diseases.

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.

Online discussion effects on intention to participate in genetic research: A longitudinal experimental study.

PubMed

Kim, Sojung Claire; Cappella, Joseph N; Price, Vincent

2016-09-01

The National Human Genome Research Institute has emphasised community engagement and public dialogue in the U.S. on issues related to genetics. This study examines how online discussions among the U.S. public directly or indirectly influence psychosocial constructs of the Theory of Planned Behavior, including intention to take part in genetic research. After completing the baseline questionnaire, participants (n = 3754) were randomly assigned to one of the following three groups: the discussion group, the pre-/post-only group and the End-of-Project group. The discussion group (n = 1824) was invited and participated in up to three online discussions, which were held from November 2008 to May 2009. Behavioural intention, beliefs, attitudes, subjective norm and perceived behavioural control variables were assessed. The most interesting finding was that those participating in online discussions had fewer negative beliefs about volunteering for genetic research, which in turn contributed to more positive attitudes, increased injunctive and descriptive norms and enhanced behavioural control. These relationships, then, were associated with higher intention to participate in genetic research. These findings suggest that continuous public discussions seem to positively affect volunteer intention for genetic research through ameliorating fears of negative consequences.

Uses and Misuses of Ted Kaczynski's MMPI.

PubMed

Ben-Porath, Yossef S

2018-05-22

Although case studies can be a helpful didactic aid when teaching personality assessment and illustrating use of a test, they can, of course, not be used as "evidence" that a test "works" or does not work. This article, however, reviews and discusses the far more problematic uses instantiated in a case study of Ted Kaczynski's Minnesota Multiphasic Personality Inventory (MMPI). A series of errors of omission and commission are identified in Butcher, Hass, Greene, and Nelson's ( 2015 ) effort to criticize the MMPI-2-RF. These include not disclosing that Butcher's interpretive Minnesota Report for Forensic Settings indicates that the protocol is invalid, not including most of the MMPI-2 and MMPI-2-RF scores that contradict the authors' assertions, and mischaracterizing the MMPI-2-RF findings. Proper use of a case study is then illustrated by a discussion of diagnostic considerations indicated by the MMPI-2-RF findings.

2011-01-01

This paper presents findings on sexual risk behaviours of Liberian youths based on five focus-group discussions conducted with 6th and 7th graders (n=36) attending an elementary/middle school in Monrovia, Liberia. The purpose of the focus-group discussions was to gain an understanding of the sexual behaviours of in-school Liberian adolescents. The focus-group discussions were part of a larger study to adapt an evi-dence-based HIV-prevention intervention—Making Proud Choices!—for in-school youths. Post-conflict conditions were discussed as a contributor to the emergence of high-risk sexual behaviours, including transactional sex, sexual violence, and lack of condom-use. Transactional sex was often described by the focus-group participants as occurring between young females and older, more financially-secure males to obtain cash, food, clothing, western commodities, and school-fees and was often encouraged by parents and promoted by peers. The findings also indicate that female adolescents make choices to engage in transactional sex to gain access to a continuum of material and consumer needs. These findings suggest that individual risk-taking behaviours are nested within complex sexual economies and that HIV-prevention interventions should be considered that leverage females’ agency and control.

Current evidence and future directions for research with omega-3 fatty acids and attention deficit hyperactivity disorder.

PubMed

Gow, Rachel V; Hibbeln, Joseph R; Parletta, Natalie

2015-03-01

Nutritional insufficiencies of nutrients such as omega-3 highly unsaturated fatty acids (HUFAs), vitamins and minerals have been linked to suboptimal developmental outcomes including attention deficit hyperactivity disorder (ADHD). Although the predominant treatment is currently psychostimulant medications, randomized clinical trials with omega-3 HUFAs have reported small-to-modest effects in reducing symptoms of ADHD in children despite arguable individual methodological and design misgivings. This review presents, discusses and critically evaluates data and findings from meta-analytic and systematic reviews and clinical trials published within the last 12 months. Recent trajectories of this research are discussed, such as comparing eicosapentaenoic acid and docosahexaenoic acid and testing the efficacy of omega-3 HUFAs as an adjunct to methylphenidate. Discussion includes highlighting limitations and potential future directions such as addressing variable findings by accounting for other nutritional deficiencies and behavioural food intolerances. The authors conclude that given the current economic burden of ADHD, estimated in the region of $77 billion in the USA alone, in addition to the fact that a proportion of patients with ADHD are either treatment resistant, nonresponders or withdraw from medication because of adverse side-effects, the investigation of nonpharmacological interventions including omega-3 HUFAs in clinical practice warrants extrapolating.

Identifying people with type 2 diabetes and those at risk: lessons from the measure your waist (MY-WAIST) mixed-methods study in UK primary care.

This paper focuses mainly on explanations and lessons from a research-based programme for identifying undiagnosed type 2 diabetes and high risk. In addition to outlining key quantitative findings, we specifically aim to explore reasons for low uptake from the perspective of primary care staff involved. The MY-WAIST study was conducted in UK primary care and included the use of oral glucose tolerance tests (OGTTs) and waist measurement. Qualitative data from interviews with healthcare providers and records of meetings were analysed thematically. The key quantitative finding was low uptake of the assessments offered (8.6% overall, 2.6% in inner-city locations with high South Asian residency). In addition to confirming patient-reported barriers including those associated with OGTTs, qualitative findings highlighted a number of primary care provider barriers, including limited staff capacity. Interviewees suggested that those who attended were typically the 'worried well' rather than those from hard-to-reach groups. Implications discussed include the impact of low uptake on the usefulness of the quantitative data obtained, and lessons relevant to research design. Relevance to current guidance regarding early identification strategies is discussed and the importance of addressing the needs of less accessible groups is highlighted.

Facilitators and barriers to discussing HIV prevention with adolescents: perspectives of HIV-infected parents.

PubMed

Edwards, Laura L; Reis, Janet S; Weber, Kathleen M

2013-08-01

We examined HIV-infected parents' conversations about HIV prevention with their uninfected children, including what facilitated or hindered communication. Parents with HIV/AIDS (n = 90) who had children aged 10 to 18 years were recruited for a mixed method study from 2009 to 2010. Interviews assessed facilitators and barriers to discussing HIV prevention. A questionnaire identified the frequency and content of conversations, parental confidence level, and perceived importance of discussing preventive topics. Eighty-one percent of parents reported "sometimes" or "often" communicating about HIV prevention. A subset of parents found these conversations difficult; 44% indicated their desire for support. Facilitators to communication included utilizing support, focusing on the benefits of talking, and having a previous relationship with one's child. Barriers to discussions included fear of negative consequences, living in denial, and lacking a parental role model who discussed safer sex. Parents varied as to how they believed their HIV status affected communication. Those who did not disclose their HIV status to their children reported less frequent communication; self-efficacy partially mediated this relationship. Findings highlighted the need for communication skills training that support HIV-infected parents in their efforts to discuss HIV-related information with adolescents.

DisVis: Visualizing Discussion Threads in Online Health Communities.

PubMed

Nakikj, Drashko; Mamykina, Lena

2016-01-01

An increasing number of individuals turn to online health communities (OHC) for information, advice and support about their health condition or disease. As a result of users' active participation, these forums store overwhelming volumes of information, which can make access to this information challenging and frustrating. To help overcome this problem we designed a discussion visualization tool DisVis. DisVis includes features for overviewing, browsing and finding particular information in a discussion. In a between subjects study, we tested the impact of DisVis on individuals' ability to provide an overview of a discussion, find topics of interest and summarize opinions. The study showed that after using the tool, the accuracy of participants' answers increased by 68% (p-value = 0.023) while at the same time exhibiting trends for reducing the time to answer by 38% with no statistical significance (p-value = 0.082). Qualitative interviews showed general enthusiasm regarding tools for improving browsing and searching for information within discussion forums, suggested different usage scenarios, highlighted opportunities for improving the design of DisVis, and outlined new directions for visualizing user-generated content within OHCs.

Empathy-related Responding: Associations with Prosocial Behavior, Aggression, and Intergroup Relations

Empathy-related responding, including empathy, sympathy, and personal distress, has been implicated in conceptual models and theories about prosocial behavior and altruism, aggression and antisocial behavior, and intergroup relationships. Conceptual arguments and empirical findings related to each of these topics are reviewed. In general, there is evidence that empathy and/or sympathy are important correlates of, and likely contributors to, other-oriented prosocial behavior, the inhibition of aggression and antisocial behavior, and the quality of intergroup relationships. Applied implications of these findings, including preventative studies, are discussed, as are possible future directions. PMID:21221410

PADF RF localization experiments with multi-agent caged-MAV platforms

NASA Astrophysics Data System (ADS)

2011-06-01

This paper provides a summary of preliminary RF direction finding results generated within an AFOSR funded testbed facility recently developed at Louisiana Tech University. This facility, denoted as the Louisiana Tech University Micro- Aerial Vehicle/Wireless Sensor Network (MAVSeN) Laboratory, has recently acquired a number of state-of-the-art MAV platforms that enable us to analyze, design, and test some of our recent results in the area of multiplatform position-adaptive direction finding (PADF) [1] [2] for localization of RF emitters in challenging embedded multipath environments. Discussions within the segmented sections of this paper include a description of the MAVSeN Laboratory and the preliminary results from the implementation of mobile platforms with the PADF algorithm. This novel approach to multi-platform RF direction finding is based on the investigation of iterative path-loss based (i.e. path loss exponent) metrics estimates that are measured across multiple platforms in order to develop a control law that robotically/intelligently positionally adapt (i.e. self-adjust) the location of each distributed/cooperative platform. The body of this paper provides a summary of our recent results on PADF and includes a discussion on state-of-the-art Sensor Mote Technologies as applied towards the development of sensor-integrated caged-MAV platform for PADF applications. Also, a discussion of recent experimental results that incorporate sample approaches to real-time singleplatform data pruning is included as part of a discussion on potential approaches to refining a basic PADF technique in order to integrate and perform distributed self-sensitivity and self-consistency analysis as part of a PADF technique with distributed robotic/intelligent features. These techniques are extracted in analytical form from a parallel study denoted as "PADF RF Localization Criteria for Multi-Model Scattering Environments". The focus here is on developing and reporting specific approaches to self-sensitivity and self-consistency within this experimental PADF framework via the exploitation of specific single-agent caged-MAV trajectories that are unique to this experiment set.

Imaging studies including magnetic resonance imaging (MRI) play a crucial role in the diagnosis and staging of hepatocellular carcinoma (HCC). Several recent studies reveal a large number of MRI features related to the prognosis of HCC. In this review, we discuss various MRI features of HCC and their implications for the diagnosis and prognosis as imaging biomarkers. As a whole, the favorable MRI findings of HCC are small size, encapsulation, intralesional fat, high apparent diffusion coefficient (ADC) value, and smooth margins or hyperintensity on the hepatobiliary phase of gadoxetic acid-enhanced MRI. Unfavorable findings include large size, multifocality, low ADC value, non-smooth margins or hypointensity on hepatobiliary phase images. MRI findings are potential imaging biomarkers in patients with HCC. PMID:25995679

Structural, functional and spectroscopic MRI studies of methamphetamine addiction.

PubMed

Salo, Ruth; Fassbender, Catherine

2012-01-01

This chapter reviews selected neuroimaging findings related to long-term amphetamine and methamphetamine (MA) use. An overview of structural and functional (fMRI) MR studies, Diffusion Tensor Imaging (DTI), Magnetic Resonance Spectroscopy (MRS) and Positron Emission Tomography (PET) studies conducted in long-term MA abusers is presented. The focus of this chapter is to present the relevant studies as tools to understand brain changes following drug abstinence and recovery from addiction. The behavioral relevance of these neuroimaging studies is discussed as they relate to clinical symptoms and treatment. Within each imaging section this chapter includes a discussion of the relevant imaging studies as they relate to patterns of drug use (i.e., duration of MA use, cumulative lifetime dose and time MA abstinent) as well as an overview of studies that link the imaging findings to cognitive measures. In our conclusion we discuss some of the future directions of neuroimaging as it relates to the pathophysiology of addiction.

Patient-reported outcomes, patient-reported information: from randomized controlled trials to the social web and beyond.

Internet communication is developing. Social networking sites enable patients to publish and receive communications very easily. Many stakeholders, including patients, are using these media to find new ways to make sense of diseases, to find and discuss treatments, and to give support to patients and their caregivers. We argue for a new definition of patient-reported information (PRI), which differs from the usual patient-reported outcomes (PRO). These new emergent data from the social web have important implications for decision making, at both an individual and a population level. We discuss new emergent technologies that will help aggregate this information and discuss how this will be assessed alongside the use of PROs in randomized controlled trials and how these new emergent data will be one facet of changing the relationship between the various stakeholders in achieving better co-created health.

A comparison of on-campus first year undergraduate nursing students' experiences with face-to-face and on-line discussions.

PubMed

Jacobsen, Hilary E

2006-08-01

Only limited pedagogical use has been made of information and communications technology (ICT) in nursing education in Norway. In this study the use of ICT was linked to assignments in the first year undergraduate nursing program and included four on-line discussions. There is evidence to suggest that on-line discussions can enhance the learning environment. The students' experiences of the on-line discussions are compared to those of the students participating in traditional group discussions. The results show little difference between the two groups' opinions of the discussions' fruitfulness and the ease in which they expressed their feelings, thoughts and ideas. However, there is a marked difference between the two groups regarding their experience of how the discussions affected the amount of contact between group members outside the discussions. Possible reasons for these findings are discussed.

Online Discussion Effects on Intention to Participate in Genetic Research: A Longitudinal Experimental Study

Kim, Sojung Claire; Cappella, Joseph N.; Price, Vincent

2016-01-01

Objective The National Human Genome Research Institute has emphasized community engagement and public dialogue in the U. S. on issues related to genetics. This study examines how online discussions among the U.S. public directly or indirectly influence psychosocial constructs of the Theory of Planned Behavior (TPB), including intention to take part in genetic research. Design After completing the baseline questionnaire, participants (n = 3,754) were randomly assigned to one of the following three groups: the discussion group, the pre/post only group, and the End-Of-Project group. The discussion group (n = 1,824) was invited and participated in up to three online discussions, which were held from November 2008 to May 2009. Main Outcome Measures Behavioral intention, beliefs, attitudes, subjective norm, and perceived behavioral control variables were assessed. Results The most interesting finding was that those participating in online discussions had fewer negative beliefs about volunteering for genetic research, which in turn, contributed to more positive attitudes, increased injunctive and descriptive norms, and enhanced behavioral control. These relationships, then, were associated with higher intention to participate in genetic research. Conclusion These findings suggest that continuous public discussions seem to positively affect volunteer intention for genetic research through ameliorating fears of negative consequences.

Cont-Bouchaud Percolation Model Including Tobin Tax

NASA Astrophysics Data System (ADS)

Ehrenstein, Gudrun

The Tobin tax is an often discussed method to tame speculation and get a source of income. The discussion is especially heated when the financial markets are in crisis. In this article we refer to the foreign exchange markets. The Tobin tax should be a small international tax affecting all currency transactions and thus consequently reducing destabilizing speculations. In this way this tax should take over a control function. By including the Tobin tax in the microscopic model of Cont and Bouchaud one finds that this tax could be the right method to control foreign exchange operations and to get a good source of income.

Facilitators and Barriers to Discussing HIV Prevention With Adolescents: Perspectives of HIV-Infected Parents

PubMed Central

Reis, Janet S.; Weber, Kathleen M.

2013-01-01

Objectives. We examined HIV-infected parents’ conversations about HIV prevention with their uninfected children, including what facilitated or hindered communication. Methods. Parents with HIV/AIDS (n = 90) who had children aged 10 to 18 years were recruited for a mixed method study from 2009 to 2010. Interviews assessed facilitators and barriers to discussing HIV prevention. A questionnaire identified the frequency and content of conversations, parental confidence level, and perceived importance of discussing preventive topics. Results. Eighty-one percent of parents reported “sometimes” or “often” communicating about HIV prevention. A subset of parents found these conversations difficult; 44% indicated their desire for support. Facilitators to communication included utilizing support, focusing on the benefits of talking, and having a previous relationship with one’s child. Barriers to discussions included fear of negative consequences, living in denial, and lacking a parental role model who discussed safer sex. Parents varied as to how they believed their HIV status affected communication. Those who did not disclose their HIV status to their children reported less frequent communication; self-efficacy partially mediated this relationship. Conclusions. Findings highlighted the need for communication skills training that support HIV-infected parents in their efforts to discuss HIV-related information with adolescents. PMID:23763390

2018-04-01

Spontaneous findings noted in the eyes of Mauritian cynomolgus monkeys are described and descriptions are supplemented with illustrations. Findings observed after extensive histopathologic examinations (20 to 44 sections per eye) from 20 control, 17 treatment-naive stock monkeys, and 2 findings noted in drug-treated monkeys that were considered to be spontaneous are included. Also included are findings from 361 control monkeys of routine toxicity studies performed at our laboratories, for most of which a standard histopathological examination of 1 section per eye was conducted. Common observations in monkeys examined extensively and in historical controls were limited to lymphocytic or mononuclear cell infiltrations of the uvea and/or conjunctiva/sclera and, less commonly observed, melanocytoma of the ciliary body or iris. Findings noted only in monkeys examined extensively consisted of inflammation of the conjunctiva, ora serrata cysts, glial nodules, focal degeneration of the retina, cystoid degeneration of the central retina, ballooning degeneration of the ciliary epithelium, cyst of the ciliary body, and decreased pigmentation of the retinal pigment epithelium. Changes recorded only in historical controls included retinal atrophy and nuclear displacement in the retina. Lesions are discussed and compared with pertinent literature.

Vehicle Motions as Inferred from Radio-signal- Strength Records

NASA Technical Reports Server (NTRS)

Pilkington, W. C.

1958-01-01

Considerable data on various parameters of a satellite and its launching vehicle can be obtained from the received-signal-strength records at the various satellite receiver stations. The doppler shifts of the satellite can be used to determine the orbital characteristics quite accurately. (Ref. 1 discusses the rapid determination of these parameters.) Information concerning the velocity increment and direction of each stage can be obtained if doppler data are received by several stations during the high-speed staging. The variations in signal strength during launch can be used to find the spin rate of the satellite before, during, and after staging, and to find variations in attitude, including precession, during launch. With spin and precession frequencies available, any changes in the ratios of moments of inertia can be determined. In this paper the launchings of the Explorer satellites will be used as a basis for the generalized conclusions concerning utilization of radio-signal-strength records. The discussion includes a description of the Explorer launching system.

Symptom Dimensions in Obsessive-Compulsive Disorder: Phenomenology and Treatment Outcomes with Exposure and Ritual Prevention

PubMed Central

Williams, Monnica T.; Mugno, Beth; Franklin, Martin; Faber, Sonya

2014-01-01

Obsessive-compulsive disorder (OCD) is a severe condition with varied symptom presentations. The cognitive-behavioral treatment with the most empirical support is currently exposure and ritual prevention (EX/RP); however, clinical impression and some empirical data suggest that certain OCD symptoms are more responsive to treatment than others. Prior work identifying symptom dimensions within OCD is discussed, including epidemiological findings, factor analytic studies, and biological findings. Symptom dimensions most reliably identified include contamination/cleaning, doubt about harm/checking, symmetry/ordering, and unacceptable thoughts/mental rituals. The phenomenology of each of these subtypes is described and research literature is summarized, emphasizing the differential effects of EX/RP and its variants on each of these primary symptom dimensions. To date it appears that EX/RP is an effective treatment for the various OCD dimensions, although not all dimensions have been adequately studied (i.e., symmetry and ordering). Modifications to treatment may be warranted for some types of symptoms. Clinical implications and directions for future research are discussed. PMID:23615340

Knowledge, attitudes and practices on adolescent vaccination among parents, teachers and adolescents in Africa: a systematic review protocol

PubMed Central

2014-01-01

Background Vaccines are the most successful and cost-effective public health interventions available to avert vaccine-preventable diseases and deaths. Despite progress in the field of adolescent health, many young people in Africa still get sick and die from vaccine-preventable diseases due to lack of vaccination. Parents, adolescents and teachers are key players with regard to implementation of adolescent vaccination policies. Therefore, understanding their knowledge, attitudes and practices towards adolescent vaccination may provide clues on what can be done to improve vaccine uptake among adolescents. The aim of this study is to conduct a qualitative and quantitative systematic review on knowledge, attitudes and practices on adolescent vaccination among parents, teachers and adolescents in Africa. Methods We will include both quantitative and qualitative primary studies. Eligible quantitative studies include both intervention and observational studies. Qualitative studies to be included are focus group discussions, direct observations, in-depth interviews and case ethnographic studies. We will search PubMed, Cochrane Central Register of Controlled Trials, Scopus, Web of Science, WHOLIS, Africa Wide and CINAHL for eligible studies with no time and language limits. We will also check reference lists of included studies for other eligible reports. Two authors will independently screen the search output, select studies and extract data, resolving discrepancies by consensus and discussion. We will analyse qualitative data using thematic analysis where applicable, and quantitative studies findings will be presented in a narrative synthesis form based on the outcomes. Discussion The findings from this systematic review will guide the identification of gaps on knowledge, attitudes and practices among the key role players on adolescent vaccination. We anticipate that our findings will guide the development of adolescent-focused vaccination policy in Africa, which is virtually non-existent at present. Systematic review registration This review is registered with PROSPERO, registration number CRD42014010395. PMID:25200458

Levine, Marc S; Carucci, Laura R

2018-06-01

Fluoroscopic esophagography is a widely available, safe, and inexpensive test for detecting gastroesophageal reflux disease. In this article, we review the technique for performing a high-quality esophagram, including upright, double-contrast views of the esophagus and cardia with high-density barium; prone, single-contrast views of the esophagus with low-density barium; and evaluation of gastroesophageal reflux. We then discuss the radiographic findings associated with gastroesophageal reflux disease, including esophageal dysmotility, reflux esophagitis, peptic strictures, and Barrett's esophagus. Finally, we consider the differential diagnosis for the various radiographic findings associated with this condition. When carefully performed and interpreted, the esophagram is a useful test for evaluating gastroesophageal reflux disease and its complications.

Neural stem cell heterogeneity through time and space in the ventricular-subventricular zone.

PubMed

Rushing, Gabrielle; Ihrie, Rebecca A

2016-08-01

The origin and classification of neural stem cells (NSCs) has been a subject of intense investigation for the past two decades. Efforts to categorize NSCs based on their location, function and expression have established that these cells are a heterogeneous pool in both the embryonic and adult brain. The discovery and additional characterization of adult NSCs has introduced the possibility of using these cells as a source for neuronal and glial replacement following injury or disease. To understand how one could manipulate NSC developmental programs for therapeutic use, additional work is needed to elucidate how NSCs are programmed and how signals during development are interpreted to determine cell fate. This review describes the identification, classification and characterization of NSCs within the large neurogenic niche of the ventricular-subventricular zone (V-SVZ). A literature search was conducted using Pubmed including the keywords "ventricular-subventricular zone," "neural stem cell," "heterogeneity," "identity" and/or "single cell" to find relevant manuscripts to include within the review. A special focus was placed on more recent findings using single-cell level analyses on neural stem cells within their niche(s). This review discusses over 20 research articles detailing findings on V-SVZ NSC heterogeneity, over 25 articles describing fate determinants of NSCs, and focuses on 8 recent publications using distinct single-cell analyses of neural stem cells including flow cytometry and RNA-seq. Additionally, over 60 manuscripts highlighting the markers expressed on cells within the NSC lineage are included in a chart divided by cell type. Investigation of NSC heterogeneity and fate decisions is ongoing. Thus far, much research has been conducted in mice however, findings in human and other mammalian species are also discussed here. Implications of NSC heterogeneity established in the embryo for the properties of NSCs in the adult brain are explored, including how these cells may be redirected after injury or genetic manipulation.

There is a need to improve the rational use of antibiotics across continents including Africa. This has resulted in initiatives in Botswana including treatment guidelines and the instigation of Antibiotic Stewardship Programs (ASPs). The next steps involve a greater understanding of current antibiotic utilization and resistance patterns (AMR). This resulted in a 2-day meeting involving key stakeholders principally from Botswana to discuss key issues including AMR rates as well as ASPs in both the public and private sectors. Following this, the findings will be used to plan future studies across Africa including point prevalence studies. The findings will be presented in July 2016 at the next Medicines Utilization Research in Africa meeting will ideally serve as a basis for planning future pertinent interventional studies to enhance the rational use of antibiotics in Botswana and wider.

Sexual and dating violence among adolescents and young adults in Chile: a review of findings from a survey of university students.

PubMed

Lehrer, Jocelyn A; Lehrer, Evelyn L; Koss, Mary P

2013-01-01

This paper synthesises and discusses results from the 2005 Survey of Student Well-Being, a closed-ended questionnaire administered to students attending general education courses at a major public university in Santiago (n = 484 women, 466 men). The survey included questions on sexual violence (SV) and dating violence (DV), public health problems that have received little attention in Chile and other Latin-American countries. This paper highlights key findings from a series of papers based on these data, noting lessons learned in the Chilean context that may be useful for other Latin-American countries. Important gaps in the international literature on SV and DV are also discussed. A central finding is the high prevalence of SV and DV in this sample of university students, warranting further public health attention to these problems. Potentially, the findings will contribute to changes in awareness, policy and practice along similar lines to efforts that transformed the US landscape regarding SV and DV on college campuses in the 1980s.

A Community-Engaged Research Approach to Improve Mental Health Among Latina Immigrants: ALMA Photovoice.

Recent Latina immigrants are at increased risk of poor mental health due to stressors associated with adapting to life in the United States. Existing social and health care policies often do not adequately address the mental health concerns of new Latino populations. Amigas Latinas Motivando el Alma, a community-partnered research project, seeks to improve immigrant Latinas' mental health outcomes. Using Photovoice methodology, promotoras (lay health advisors) reflected on community factors affecting mental health through photography and guided discussion. Discussions were audio-recorded, transcribed, and coded using content analysis to identify salient themes. Promotoras reviewed codes to develop themes that they presented in community forums to reach local policy makers and to increase community awareness. These forums included an exhibit of the promotoras' photographs and discussion of action steps to address community concerns. Themes included transitioning to life in the United States, parenting, education, and combating racism. Nearly 150 stakeholders attended the community forums and proposed responses to promotoras' photographic themes. Our findings suggest that Photovoice provides an opportunity for Latinas and the larger community to identify issues that they find most important and to explore avenues for action and change by creating sustainable partnerships between the community and forum attendees. © 2015 Society for Public Health Education.

Understanding the regulation of vertebrate hematopoiesis and blood disorders: big lessons from a small fish

PubMed Central

Robertson, Anne L.; Avagyan, Serine; Gansner, John M.; Zon, Leonard I.

2017-01-01

Hematopoietic stem cells (HSCs) give rise to all differentiated blood cells. Understanding the mechanisms that regulate self-renewal and lineage specification of HSCs is key for developing treatments for many human diseases. Zebrafish have emerged as an excellent model for studying vertebrate hematopoiesis. This review will highlight the unique strengths of zebrafish and important findings that have emerged from studies of blood development and disorders using this system. We discuss recent advances in our understanding of hematopoiesis, including the origin of HSCs, molecular control of their development, and key signaling pathways involved in their regulation. We highlight significant findings from zebrafish models of blood disorders, and discuss their application for investigating stem cell dysfunction in disease and for developing new therapeutics.

Helicity coherence in binary neutron star mergers and nonlinear feedback

NASA Astrophysics Data System (ADS)

Chatelain, Amélie; Volpe, Cristina

2017-02-01

Neutrino flavor conversion studies based on astrophysical environments usually implement neutrino mixings, neutrino interactions with matter, and neutrino self-interactions. In anisotropic media, the most general mean-field treatment includes neutrino mass contributions as well, which introduce a coupling between neutrinos and antineutrinos termed helicity or spin coherence. We discuss resonance conditions for helicity coherence for Dirac and Majorana neutrinos. We explore the role of these mean-field contributions on flavor evolution in the context of a binary neutron star merger remnant. We find that resonance conditions can be satisfied in neutron star merger scenarios while adiabaticity is not sufficient for efficient flavor conversion. We analyze our numerical findings by discussing general conditions to have multiple Mikheyev-Smirnov-Wolfenstein-like resonances, in the presence of nonlinear feedback, in astrophysical environments.

NASA is investing in new technologies that include 14 primary technology roadmap areas, and aeronautics. Understanding the cost for research and development of these technologies and the time it takes to increase the maturity of the technology is important to the support of the ongoing and future NASA missions. Overall, technology estimating may help provide guidance to technology investment strategies to help improve evaluation of technology affordability, and aid in decision support. The research provides a summary of the framework development of a Technology Estimating process where four technology roadmap areas were selected to be studied. The framework includes definition of terms, discussion for narrowing the focus from 14 NASA Technology Roadmap areas to four, and further refinement to include technologies, TRL range of 2 to 6. Included in this paper is a discussion to address the evaluation of 20 unique technology parameters that were initially identified, evaluated and then subsequently reduced for use in characterizing these technologies. A discussion of data acquisition effort and criteria established for data quality are provided. The findings obtained during the research included gaps identified, and a description of a spreadsheet-based estimating tool initiated as a part of the Technology Estimating process.

Penon, Danila; Cito, Letizia; Giordano, Antonio

2014-07-21

The Tenth International Gastric Cancer Congress (IGCC) was held in Verona, Italy, from June 19 to 22, 2013. The meeting enclosed various aspects of stomach tumor management, including both tightly clinical approaches, and topics more related to basic research. Moreover, an overview on gastrointestinal stromal tumors was provided too, although here not discussed. Here we will discuss some topics related to molecular biology of gastric cancer (GC), inherent to prognostic, diagnostic and therapeutic tools shown at the conference. Results about well known subjects, such as E-cadherin loss of expression/function, were presented. They revealed that other mutations of the gene were identified, showing a continuous research to improve diagnosis and prognosis of stomach tumor. Simultaneously, new possible molecular markers with an established role for other neoplasms, were discussed, such as mesothelin, stomatin-like protein 2 and Notch-1. Hence, a wide overview including both old and new diagnostic/prognostic tools was offered. Great attention was also dedicated to possible drugs to be used against GC. They included monoclonal antibodies, such as MS57-2.1, drugs used in other pathologies, such as maraviroc, and natural extracts from plants such as biflorin. We would like to contribute to summarize the most impressive studies presented at the IGCC, concerning novel findings about molecular biology of gastric cancer. Although further investigations will be necessary, it can be inferred that more and more tools were developed, so as to better face stomach neoplasms.

Man’s Best Friend Becomes Biology’s Best in Show: Genome Analyses in the Domestic Dog*

PubMed Central

Parker, Heidi G.; Shearin, Abigail L.; Ostrander, Elaine A.

2012-01-01

In the last five years, canine genetics has gone from map construction to complex disease deconstruction. The availability of a draft canine genome sequence, dense marker chips, and an understanding of the genome architecture has changed the types of studies canine geneticists can undertake. There is now a clear recognition that the dog system offers the opportunity to understand the genetics of both simple and complex traits, including those associated with morphology, disease susceptibility, and behavior. In this review, we summarize recent findings regarding canine domestication and review new information on the organization of the canine genome. We discuss studies aimed at finding genes controlling morphological phenotypes and provide examples of the way such paradigms may be applied to studies of behavior. We also discuss the many ways in which the dog has illuminated our understanding of human disease and conclude with a discussion on where the field is likely headed in the next five years.

SOAP-V: Introducing a method to empower medical students to be change agents in bending the cost curve.

PubMed

Moser, Eileen M; Huang, Grace C; Packer, Clifford D; Glod, Susan; Smith, Cynthia D; Alguire, Patrick C; Fazio, Sara B

2016-03-01

Medical students must learn how to practice high-value, cost-conscious care. By modifying the traditional SOAP (Subjective-Objective-Assessment-Plan) presentation to include a discussion of value (SOAP-V), we developed a cognitive forcing function designed to promote discussion of high-value, cost-conscious care during patient delivery. The SOAP-V model prompts the student to consider (1) the evidence that supports a test or treatment, (2) the patient's preferences and values, and (3) the financial cost of a test or treatment compared to alternatives. Students report their findings to their teams during patient care rounds. This tool has been successfully used at 3 medical schools. Preliminary results find that students who have been trained in SOAP-V feel more empowered to address the economic healthcare crisis, are more comfortable in initiating discussions about value, and are more likely to consider potential costs to the healthcare system. © 2015 Society of Hospital Medicine.

Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen. We demonstrate that these events can be distinguished from normal-luminosity SNe (including Type Ic events) solely from their spectra over a wide range of light-curve phases. We use this distinction to select 19 SLSNe-I and four possible SLSNe-I from the Palomar Transient Factory archive (including seven previously published objects). We present 127 new spectra of these objects and combine these with 39 previously published spectra, and we use these to discuss the average spectral properties of SLSNe-I at different spectral phases. We find that Mn II most probably contributes to the ultraviolet spectral features after maximum light, and we give a detailed study of the O II features that often characterize the early-time optical spectra of SLSNe-I. We discuss the velocity distribution of O II, finding that for some SLSNe-I this can be confined to a narrow range compared to relatively large systematic velocity shifts. Mg II and Fe II favor higher velocities than O II and C II, and we briefly discuss how this may constrain power-source models. We tentatively group objects by how well they match either SN 2011ke or PTF12dam and discuss the possibility that physically distinct events may have been previously grouped together under the SLSN-I label.

Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen.

Saucier, Jason A; Caron, Sandra L

2008-01-01

This study provides an analysis of gay men's magazines, examining both the content and advertisements. Four magazine titles were selected, including The Advocate, Genre, Instinct, and Out, each targeting gay men as its target audience. These magazines were coded for both article content and advertisement content. In the advertisement analysis, both the type of advertisement and characteristics of the men depicted within the advertisement when present. The results mirror previous research findings relating to the portrayal of women, including the objectification of specific body parts and the high community standards set by the images depicted. These findings were reinforced by both the advertisements and content analyzed to include a high degree of importance being placed on having the right body type. Implications for further research are discussed.

Inflammatory bowel diseases (IBD), including Crohn’s disease and ulcerative colitis, have important extraintestinal manifestations, notably in the oral cavity. These oral manifestations can constitute important clinical clues in the diagnosis and management of IBD, and include changes at the immune and bacterial levels. Aphthous ulcers, pyostomatitis vegetans, cobblestoning and gingivitis are important oral findings frequently observed in IBD patients. Their presentations vary considerably and might be well diagnosed and distinguished from other oral lesions. Infections, drug side effects, deficiencies in some nutrients and many other diseases involved with oral manifestations should also be taken into account. This article discusses the most recent findings on the oral manifestations of IBD with a focus on bacterial modulations and immune changes. It also includes an overview on options for management of the oral lesions of IBD.

Categorization of fetal external findings in common laboratory animals, intended to make the agreement at Berlin Workshop in 2014 more practical, was proposed by the Terminology Committee of the Japanese Teratology Society at the Workshop in the 55th Japanese Teratology Society Annual Meeting in 2015. In the Workshop, 73 external findings, which had been categorized as "Gray zone" anomalies but not as "Malformation" or "Variation" in the 2014 Berlin Workshop, were discussed and classified as Malformation, "Non-structural abnormality," Variation, and "Not applicable." The proposal was based on the results of a survey conducted in 2014, where 20 facilities (including pharmaceutical, chemical, and pesticide companies and contract laboratories) and 2 selected expert teratologists in Japan were asked for their opinions on the categorization of these findings. Based on the discussion, Japanese Teratology Society members have agreed that 42 out of the 73 findings can be classified as Malformations (38), Non-structural abnormalities (3), Malformations/Non-structural abnormalities (1), and Variations (0), while the remaining 31 findings were recommended to be categorized as Not applicable for fetuses. The details of the classification are shown on the website of the Japanese Teratology Society (http://www.umin.ac.jp/cadb/External.pdf). © 2018 Japanese Teratology Society.

This talk discusses the importance of providing a process operator with concise information about a process fault including a root cause diagnosis of the problem, a suggested best action for correcting the fault, and prioritization of the problem set. A decision tree approach is used to illustrate one type of approach for determining the root cause of a problem. Fault detection in several different types of scenarios is addressed, including pump malfunctions and pipeline leaks. The talk stresses the need for a good data rectification strategy and good process models along with a method for presenting the findings to the process operator in a focused and understandable way. A real time expert system is discussed as an effective tool to help provide operators with this type of information. The use of expert systems in the analysis of actual versus predicted results from neural networks and other types of process models is discussed.

Influences of social power and normative support on condom use decisions: a research synthesis

2016-01-01

A meta-analysis of 58 studies involving 30,270 participants examined how study population and methodological characteristics influence the associations among norms, control perceptions, attitudes, intentions and behaviour in the area of condom use. Findings indicated that control perceptions generally correlated more strongly among members of societal groups that lack power, including female, younger individuals, ethnic-minorities and people with lower educational levels. Furthermore, norms generally had stronger influences among younger individuals and among people who have greater access to informational social support, including males, ethnic majorities and people with higher levels of education. These findings are discussed in the context of HIV prevention efforts. PMID:15370059

This commentary discusses the findings and conclusions of the paper "Drug resistant human Staphylococcus aureus findings in sanctuary apes and its threat to wild ape populations." This paper confirms the zoonotic transfer of Staphylococcus aureus in a sanctuary setting. The assertion that this in itself is enough to reconsider the conservation potential of ape reintroduction provides an opportunity to discuss risk analysis of pathogen transmission, following IUCN guidelines, using S. aureus as an example. It is concluded that ape reintroduction projects must have disease risk mitigation strategies that include effective biosecurity protocols and pathogen surveillance. These strategies will assist with creating a well planned and executed reintroduction. This provides one way to enforce habitat protection, to minimise human encroachment and the risks from the illegal wildlife trade. Thus reintroduction must remain a useful tool in the conservation toolbox. © 2012 Wiley Periodicals, Inc.

2017-01-01

The continuing education course on integrating clinical and anatomical pathology data was designed to communicate the importance of using a weight of evidence approach to interpret safety findings in toxicology studies. This approach is necessary, as neither clinical nor anatomic pathology data can be relied upon in isolation to fully understand the relationship between study findings and the test article. Basic principles for correlating anatomic pathology and clinical pathology findings and for integrating these with other study end points were reviewed. To highlight these relationships, a series of case examples, presented jointly by a clinical pathologist and an anatomic pathologist, were used to illustrate the collaborative effort required between clinical and anatomical pathologists. In addition, the diagnostic utility of traditional liver biomarkers was discussed using results from a meta-analysis of rat hepatobiliary marker and histopathology data. This discussion also included examples of traditional and novel liver and renal biomarker data implementation in nonclinical toxicology studies to illustrate the relationship between discrete changes in biochemistry and tissue morphology.

In 1986-87, a qualitative research project was conducted in the Dominican Republic, Egypt, Indonesia, and Thailand to expand understanding of the acceptability of NORPLANT contraceptive implants beyond inferences made on the basis of continuation rates. In each of the four study sites, focus group discussions or in-depth interviews were held with potential acceptors, current NORPLANT users, discontinuers, husbands of women in these three groups, and service providers. Nonclinical participants generally had little formal education and lived primarily in urban or semi-urban areas where NORPLANT has been available for at least five years. The study focused on attitudes, perceptions, and experiences of each group regarding NORPLANT implants. Results suggest that factors having an impact on the acceptability of NORPLANT implants fall into three general categories: medical/technical, cultural/religious, and informational/educational. This article discusses each of these categories, including programmatic implications of the findings, and puts forward recommendations for enhancing NORPLANT introduction efforts on the basis of these findings.

Factors influencing food choices of adolescents: findings from focus-group discussions with adolescents.

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

2014 Trans-Atlantic Research and Development Interchange ...

EPA Pesticide Factsheets

The Trans-Atlantic Research and Development Interchange on Sustainability (TARDIS) has been bringing together a select group of scientists and engineers for in-depth discussions on sustainability on a bi-annual basis since 2004. TARDIS 2014 included twenty eight individuals from across the globe discussing issues related to progress towards sustainability. The discussion included policies, technologies, societal structure and norms, business practices and culture, and time-frames. As discussed later, the focus was on four questions: (1) what progress has been accomplished in sustainability? (2) why has there not been more progress in moving societies towards sustainability? (3) what are the road-blocks to progress towards sustainability? (4) what are the policies, technologies, and other changes that are needed to make further progress towards sustainability? One salient conclusion from TARDIS 2014 is that while sustainability has entered mainstream thinking, significant social, economic, technological, and business barriers remain to further progress towards a sustainable path as discussed throughout this report. The Trans-Atlantic Research and Development Interchange on Sustainability is a bi-annual workshop alternatively held in the United States and Austria. The purpose is to bring the best thinkers from across the globe to discuss, explore, and clarify major issues related to sustainability.

The intergenerational transfer of psychosocial risk: mediators of vulnerability and resilience.

PubMed

Serbin, Lisa A; Karp, Jennifer

2004-01-01

The recurrence of social, behavioral, and health problems in successive generations of families is a prevalent theme in both the scientific and popular literatures. This review discusses recent conceptual models and findings from longitudinal studies concerning the intergenerational transfer of psychosocial risk, including intergenerational continuity, and the processes whereby a generation of parents may place their offspring at elevated risk for social, behavioral, and health problems. Key findings include the mediational effects of parenting and environmental factors in the transfer of risk. In both girls and boys, childhood aggression and antisocial behavior appear to predict long-term trajectories that place offspring at risk. Sequelae of childhood aggression that may threaten the well-being of offspring include school failure, adolescent risk-taking behavior, early and single parenthood, and family poverty. These childhood and adolescent behavioral styles also predict harsh, aggressive, neglectful, and unstimulating parenting behavior toward offspring. Buffering factors within at-risk families include maternal educational attainment and constructive parenting practices (e.g., emotional warmth, consistent disciplinary practices, and cognitive scaffolding). These findings highlight the potential application and relevance of intergenerational studies for social, educational, and health policy.

African Americans are consistently underrepresented in cancer clinical trials. Minority under-enrolment may be, in part, due to differences in the way clinical trials are discussed in oncology visits with African American vs. White patients. To investigate differences in oncologist-patient communication during offers to participate in clinical trials in oncology visits with African American and White patients. From an archive of video-recorded oncology visits, we selected all visits with African American patients that included a trial offer (n = 11) and a matched sample of visits with demographically/medically comparable White patients (n = 11). Using mixed qualitative-quantitative methods, we assessed differences by patient race in (i) word count of entire visits and (ii) frequency of mentions and word count of discussions of clinical trials and key elements of consent. Visits with African American patients, compared to visits with White patients, were shorter overall and included fewer mentions of and less discussion of clinical trials. Also, visits with African Americans included less discussion of the purpose and risks of trials offered, but more discussion of voluntary participation. African American patients may make decisions about clinical trial participation based on less discussion with oncologists than do White patients. Possible explanations include a less active communication style of African Americans in medical visits, oncologists' concerns about patient mistrust, and/or oncologist racial bias. Findings suggest oncologists should pay more conscious attention to developing the topic of clinical trials with African American patients, particularly purpose and risks. © 2013 John Wiley & Sons Ltd.

Revisiting the reported signal of acute pancreatitis with rasburicase: an object lesson in pharmacovigilance

PubMed Central

Hauben, Manfred; Hung, Eric Y.

2016-01-01

Introduction: There is an interest in methodologies to expeditiously detect credible signals of drug-induced pancreatitis. An example is the reported signal of pancreatitis with rasburicase emerging from a study [the ‘index publication’ (IP)] combining quantitative signal detection findings from a spontaneous reporting system (SRS) and electronic health records (EHRs). The signal was reportedly supported by a clinical review with a case series manuscript in progress. The reported signal is noteworthy, being initially classified as a false-positive finding for the chosen reference standard, but reclassified as a ‘clinically supported’ signal. Objective: This paper has dual objectives: to revisit the signal of rasburicase and acute pancreatitis and extend the original analysis via reexamination of its findings, in light of more contemporary data; and to motivate discussions on key issues in signal detection and evaluation, including recent findings from a major international pharmacovigilance research initiative. Methodology: We used the same methodology as the IP, including the same disproportionality analysis software/dataset for calculating observed to expected reporting frequencies (O/Es), Medical Dictionary for Regulatory Activities Preferred Term, and O/E metric/threshold combination defining a signal of disproportionate reporting. Baseline analysis results prompted supplementary analyses using alternative analytical choices. We performed a comprehensive literature search to identify additional published case reports of rasburicase and pancreatitis. Results: We could not replicate positive findings (e.g. a signal or statistic of disproportionate reporting) from the SRS data using the same algorithm, software, dataset and vendor specified in the IP. The reporting association was statistically highlighted in default and supplemental analysis when more sensitive forms of disproportionality analysis were used. Two of three reports in the FAERS database were assessed as likely duplicate reports. We did not identify any additional reports in the FAERS corresponding to the three cases identified in the IP using EHRs. We did not identify additional published reports of pancreatitis associated with rasburicase. Discussion: Our exercise stimulated interesting discussions of key points in signal detection and evaluation, including causality assessment, signal detection algorithm performance, pharmacovigilance terminology, duplicate reporting, mechanisms for communicating signals, the structure of the FAERs database, and recent results from a major international pharmacovigilance research initiative.

A Campus-Wide Investigation of Clicker Implementation: The Status of Peer Discussion in STEM Classes

PubMed Central

Lewin, Justin D.; Vinson, Erin L.; Stetzer, MacKenzie R.; Smith, Michelle K.

2016-01-01

At the University of Maine, middle and high school teachers observed more than 250 university science, technology, engineering, and mathematics classes and collected information on the nature of instruction, including how clickers were being used. Comparisons of classes taught with (n = 80) and without (n = 184) clickers show that, while instructional behaviors differ, the use of clickers alone does not significantly impact the time instructors spend lecturing. One possible explanation stems from the observation of three distinct modes of clicker use: peer discussion, in which students had the opportunity to talk with one another during clicker questions; individual thinking, in which no peer discussion was observed; and alternative collaboration, in which students had time for discussion, but it was not paired with clicker questions. Investigation of these modes revealed differences in the range of behaviors, the amount of time instructors lecture, and how challenging the clicker questions were to answer. Because instructors can vary their instructional style from one clicker question to the next, we also explored differences in how individual instructors incorporated peer discussion during clicker questions. These findings provide new insights into the range of clicker implementation at a campus-wide level and how such findings can be used to inform targeted professional development for faculty.

Clean hands: prevention of typhoid fever in rural communities in Egypt.

PubMed

Lohiniva, Anna L; Saeed, Mohamed; El-Sayeed, Nasr; Talaat, Maha

Typhoid fever is a serious public health problem in Egypt. Effective prevention strategies include the promotion of handwashing. This study explores factors that influence handwashing practices in the Egyptian setting and makes recommendations on how to use this information in a handwashing campaign. In addition to key informant interviews, 16 focus group discussions and 21 in-depth interviews were carried out with female respondents in three different rural sites. The data was analyzed by using content analysis technique. The findings showed that the concept of dirt (microbaat and talaus) influences hygiene behavior as it relates to the outside (i.e., real and visible things). The respondents have low risk perceptions related to typhoid fever and they do not conceptualize long disease transmission chains. The scarcity of water and problems with disposal of waste water hinder handwashing. These findings were incorporated into a pilot campaign to promote handwashing using strategies that included the visualization of germs in critical areas during critical times, discussions of germ theory, and encouragement to solve environmental and infrastructural constraints that hinder handwashing practices at the household level.

Symptom dimensions in obsessive-compulsive disorder: phenomenology and treatment outcomes with exposure and ritual prevention.

PubMed

Williams, Monnica T; Mugno, Beth; Franklin, Martin; Faber, Sonya

2013-01-01

Obsessive-compulsive disorder (OCD) is a severe condition with varied symptom presentations. Currently, the cognitive-behavioral treatment with the most empirical support is exposure and ritual prevention (EX/RP); however, clinical impression and some empirical data suggest that certain OCD symptoms are more responsive to treatment than others. Prior work identifying symptom dimensions within OCD is discussed, including epidemiological findings, factor analytic studies, and biological findings. Symptom dimensions most reliably identified include contamination/cleaning, doubt about harm/checking, symmetry/ordering, and unacceptable thoughts/mental rituals. The phenomenology of each of these subtypes is described and research literature is summarized, emphasizing the differential effects of EX/RP and its variants on each of these primary symptom dimensions. To date it appears that EX/RP is an effective treatment for the various OCD dimensions, although not all dimensions have been adequately studied (i.e. symmetry and ordering). Modifications to treatment may be warranted for some types of symptoms. Clinical implications and directions for future research are discussed. Copyright © 2013 S. Karger AG, Basel.

1985-01-01

The purpose is to describe work that is being done to find theoretical models to describe radar backscatter from vegetation layers. The geometry of the problem is shown. The information that one would like to find through the application of the results of these models would include: the thickness of the layer; the absorption in the layer (i.e., density, moisture content, and biomass); the geometry of the scatterers (i.e., shape and orientation); how much of the received power is due to volume scattering only; and a way to enhance the ratio of scattering that has some interaction with the ground surface. The proposed ways to find this information are discussed.

Consulting communities on feedback of genetic findings in international health research: sharing sickle cell disease and carrier information in coastal Kenya

PubMed Central

2013-01-01

Background International health research in malaria-endemic settings may include screening for sickle cell disease, given the relationship between this important genetic condition and resistance to malaria, generating questions about whether and how findings should be disclosed. The literature on disclosing genetic findings in the context of research highlights the role of community consultation in understanding and balancing ethically important issues from participants’ perspectives, including social forms of benefit and harm, and the influence of access to care. To inform research practice locally, and contribute to policy more widely, this study aimed to explore the views of local residents in Kilifi County in coastal Kenya on how researchers should manage study-generated information on sickle cell disease and carrier status. Methods Between June 2010 and July 2011, we consulted 62 purposively selected Kilifi residents on how researchers should manage study-generated sickle cell disease findings. Methods drew on a series of deliberative informed small group discussions. Data were analysed thematically, using charts, to describe participants’ perceptions of the importance of disclosing findings, including reasoning, difference and underlying values. Themes were derived from the underlying research questions and from issues emerging from discussions. Data interpretation drew on relevant areas of social science and bioethics literature. Results Perceived health and social benefits generated strong support for disclosing findings on sickle cell disease, but the balance of social benefits and harms was less clear for sickle cell trait. Many forms of health and social benefits and harms of information-sharing were identified, with important underlying values related to family interests and the importance of openness. The influence of micro and macro level contextual features and prioritization of values led to marked diversity of opinion. Conclusions The approach demonstrates a high ethical importance in many malaria endemic low-to-middle income country settings of disclosing sickle cell disease findings generated during research, alongside provision of effective care and locally-informed counselling. Since these services are central to the benefits of disclosure, health researchers whose studies include screening for sickle cell disease should actively promote the development of health policy and services for this condition in situations of unmet need, including through the prior development of collaborative partnerships with government health managers and providers. Community consultation can importantly enrich ethical debate on research practice where in-depth exploration of informed views and the potential for difference are taken into account. PMID:24125465

Prairie voles (Microtus ochrogaster) are socially monogamous rodents that form pair bonds—a behavior composed of several social interactions including attachment with a familiar mate and aggression toward conspecific strangers. Therefore, this species has provided an excellent opportunity for the study of pair bonding behavior and its underlying neural mechanisms. In this chapter, we discuss the utility of this unique animal model in the study of aggression and review recent findings illustrating the neurochemical mechanisms underlying pair bonding-induced aggression. Implications of this research for our understanding of the neurobiology of human violence are also discussed. PMID:22078479

The successful adoption of technology is becoming increasingly important to functional independence. The present article reports findings from the Center for Research and Education on Aging and Technology Enhancement (CREATE) on the use of technology among community-dwelling adults. The sample included 1,204 individuals ranging in age from 18–91 years. All participants completed a battery that included measures of demographic characteristics, self-rated health, experience with technology, attitudes toward computers, and component cognitive abilities. Findings indicate that the older adults were less likely than younger adults to use technology in general, computers, and the World Wide Web. The results also indicate that computer anxiety, fluid intelligence, and crystallized intelligence were important predictors of the use of technology. The relationship between age and adoption of technology was mediated by cognitive abilities, computer self-efficacy, and computer anxiety. These findings are discussed in terms of training strategies to promote technology adoption. PMID:16768579

The star formation history of redshift z ~ 2 galaxies: the role of the infrared prior

NASA Astrophysics Data System (ADS)

Fan, Lu-Lu; Lapi, Andrea; Bressan, Alessandro; Nonino, Mario; De Zotti, Gianfranco; Danese, Luigi

2014-01-01

We build a sample of 298 spectroscopically-confirmed galaxies at redshift z ~ 2, selected in the z850-band from the GOODS-MUSIC catalog. By utilizing the rest frame 8 μm luminosity as a proxy of the star formation rate (SFR), we check the accuracy of the standard SED-fitting technique, finding it is not accurate enough to provide reliable estimates of the physical parameters of galaxies. We then develop a new SED-fitting method that includes the IR luminosity as a prior and a generalized Calzetti law with a variable RV. Then we exploit the new method to re-analyze our galaxy sample, and to robustly determine SFRs, stellar masses and ages. We find that there is a general trend of increasing attenuation with the SFR. Moreover, we find that the SFRs range between a few to 103 Msolar yr-1, the masses from 109 to 4 × 1011 Msolar, and the ages from a few tens of Myr to more than 1 Gyr. We discuss how individual age measurements of highly attenuated objects indicate that dust must have formed within a few tens of Myr and already been copious at <=100 Myr. In addition, we find that low luminosity galaxies harbor, on average, significantly older stellar populations and are also less massive than brighter ones; we discuss how these findings and the well known ‘downsizing’ scenario are consistent in a framework where less massive galaxies form first, but their star formation lasts longer. Finally, we find that the near-IR attenuation is not scarce for luminous objects, contrary to what is customarily assumed; we discuss how this affects the interpretation of the observed M*/L ratios.

2011-01-01

Estimations of time and number share many similarities in both non-humans and man. The primary focus of this review is on the development of time and number sense across infancy and childhood, and neuropsychological findings as they relate to time and number discrimination in infants and adults. Discussion of these findings is couched within a mode-control model of timing and counting which assumes time and number share a common magnitude representation system. A basic sense of time and number likely serves as the foundation for advanced numerical and temporal competence, and aspects of higher cognition—this will be discussed as it relates to typical childhood, and certain developmental disorders, including autism spectrum disorder. Directions for future research in the developmental neuroscience of time and number (NEUTIN) will also be highlighted. PMID:22408612

2014-08-01

Awareness is growing that young adults may have distinctive experiences of adult healthcare and that their needs may differ from those of other adult users. In addition, the role of adult health teams in supporting positive transitions from paediatrics is increasingly under discussion. This paper contributes to these debates. It reports a qualitative study of the experiences of young adults - all with complex chronic health conditions - as users of adult health services. Key findings from the study are reported, including an exploration of factors that help to explain interviewees' experiences. Study findings are discussed in the context of existing evidence from young adults in adult healthcare settings and theories of 'young adulthood'. Implications for training and practice are considered, and priorities for future research are identified. © 2014 Royal College of Physicians.

We compute greybody factors for near extreme Kerr black holes in D = 4 and D = 5. In D = 4 we include four charges so that our solutions can be continuously deformed to the BPS limit. In D = 5 we include two independent angular momenta so Left-Right symmetry is incorporated. We discuss the CFT interpretation of our emission amplitudes, including the overall frequency dependence and the dependence on all black hole parameters. We find that all additional parameters can be incorporated Kerr/CFT, with central charge independent of U(1) charges.

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

NASA Astrophysics Data System (ADS)

Lundqvist, Eva; Sund, Per

2016-11-01

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

The Weak Spots in Contemporary Science (and How to Fix Them)

PubMed Central

2017-01-01

Simple Summary Several fraud cases, widespread failure to replicate or reproduce seminal findings, and pervasive error in the scientific literature have led to a crisis of confidence in the biomedical, behavioral, and social sciences. In this review, the author discusses some of the core findings that point at weak spots in contemporary science and considers the human factors that underlie them. He delves into the human tendencies that create errors and biases in data collection, analyses, and reporting of research results. He presents several solutions to deal with observer bias, publication bias, the researcher’s tendency to exploit degrees of freedom in their analysis of data, low statistical power, and errors in the reporting of results, with a focus on the specific challenges in animal welfare research. Abstract In this review, the author discusses several of the weak spots in contemporary science, including scientific misconduct, the problems of post hoc hypothesizing (HARKing), outcome switching, theoretical bloopers in formulating research questions and hypotheses, selective reading of the literature, selective citing of previous results, improper blinding and other design failures, p-hacking or researchers’ tendency to analyze data in many different ways to find positive (typically significant) results, errors and biases in the reporting of results, and publication bias. The author presents some empirical results highlighting problems that lower the trustworthiness of reported results in scientific literatures, including that of animal welfare studies. Some of the underlying causes of these biases are discussed based on the notion that researchers are only human and hence are not immune to confirmation bias, hindsight bias, and minor ethical transgressions. The author discusses solutions in the form of enhanced transparency, sharing of data and materials, (post-publication) peer review, pre-registration, registered reports, improved training, reporting guidelines, replication, dealing with publication bias, alternative inferential techniques, power, and other statistical tools.

36 Years of Remote Oceanographic Laser Fluorosensing: Findings, Challenges and Pathways to Explore

NASA Astrophysics Data System (ADS)

Chekalyuk, A. M.

2009-12-01

Since its initial bright start in early 70s, the oceanographic applications of laser remote fluorosensing have been mostly driven by the enthusiastic laser geeks, who tried to transfer the recent technological advances from their laboratory breadboards to the real world. This communication provides an overview of the key milestones and advances in the oceanographic applications of remote laser fluorosensing that is used for qualitative and quantitative characterization of the key aquatic constituents, including chromophoric dissolved organic matter, phytoplankton pigments, their biomass, community structure, and photo-physiological status. The basic principles and analytical techniques, including fluorescence excitation and emission measurements, as well as active control over the media to retrieve additional information (“super-active remote sensing”), are briefly discussed and illustrated with examples of practical applications. The laser excitation sources (including solid state, tunable lasers and optical parametric oscillators) and signal detectors and analyzers (including multi-spectral and hyperspectral systems) are discussed. The advantages and limitations of various platforms (stationary settings, ships, airplanes, helicopters, unmanned autonomous vehicles (UAV), and satellites) are analyzed. The recent findings, methodological and technological developments in oceanographic applications of laser fluorescence indicate that there is a significant, still underexplored potential of remote fluorosensing that may provide new observational capabilities and serve as a useful tool for oceanographic research, bio-environmental monitoring, and validation of passive satellite retrievals.

Facilitating consumer participation: an approach to finding the 'right' consumer.

PubMed

Happell, Brenda

2010-01-01

Contemporary health care increasingly dictates that consumers of services should become active participants in the health care system. This has placed responsibility on administrators, managers and clinicians to include consumers in key strategic and decision making initiatives. However, this direction has not been accompanied by clear policies or guidelines. Consequently confusion about selecting consumers able to provide valuable input is identified as a barrier to active consumer involvement. The purpose of this paper is to address some concerns raised in the quest to find the "right" consumer, including: finding a consumer without an axe to grind; ensuring the consumer is representative of broader views; health professionals as consumer representatives. While these concerns are common they have not yet been extensively debated and discussed in the broader Literature. Strategies necessary to support consumers in participatory roles are also considered and the controversial subject of financial remuneration for consumers is also explored.

Anterior segment developmental anomalies in a 33-week-old fetus with MIDAS syndrome.

2014-01-01

We report anterior segment abnormalities in both eyes of a 33-week-old fetus endorsing the diagnosis of MIDAS (microphthalmia, dermal aplasia, and sclerocornea) syndrome. After abortion, the fetus was examined by a standard pediatric autopsy that included macroscopic and microscopic examination of both eyes. Postmortem findings included craniofacial stigmata (such as hypertelorism, a flat nose and low-set ears) and an agenesis of the corpus callosum. Array comparative genomic hybridization revealed a deletion of the short arm of the X chromosome (region Xp22.2 to p22.32). Ophthalmopathologic examination of the eyes revealed microphthalmia with anterior segment developmental anomalies, in particular sclerocornea and Peters' anomaly, respectively. General pathology findings plus the ocular findings allowed the diagnosis of MIDAS syndrome. A discussion of differential diagnoses is provided. This case report indicates that ophthalmopathologic investigation of fetal eyes can be of great value for the further classification of syndromes.

[The Mechanism of Free-Floating Discussion in a Psychiatric/Mental Health Nursing Supervisory Group].

PubMed

Chiang, Hsien-Hsien

2015-06-01

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

In or out? Methodological considerations for including and excluding findings from a meta-analysis of predictors of antiretroviral adherence in HIV-positive women

Voils, Corrine I.; Barroso, Julie; Hasselblad, Victor; Sandelowski, Margarete

2008-01-01

Aim This paper is a discussion detailing the decisions concerning whether to include or exclude findings from a meta-analysis of report of quantitative studies of antiretroviral adherence in HIV-positive women. Background Publication constraints and the absence of reflexivity as a criterion for validity in, and reporting of, quantitative research preclude detailing the many judgements made in the course of a meta-analysis. Yet, such an accounting would assist researchers better to address the unique challenges to meta-analysis presented by the bodies of research they have targeted for review, and to show the subjectivity, albeit disciplined, that characterizes the meta-analytic process. Data sources Data were 29 published and unpublished studies on antiretroviral adherence in HIV-positive women of any race/ethnicity, class, or nationality living in the United States of America. The studies were retrieved between June 2005 and January 2006 using 40 databases. Review methods Findings were included if they met the statistical assumptions of meta-analysis, including: (1) normal distribution of observations; (2) homogeneity of variances; and (3) independence of observations. Results Relevant studies and findings were excluded because of issues related to differences in study design, different operationalizations of dependent and independent variables, multiple cuts from common longitudinal data sets, and presentation of unadjusted and adjusted findings. These reasons led to the exclusion of 73% of unadjusted relationships and 87% of adjusted relationships from our data set, leaving few findings to synthesize. Conclusion Decisions made during research synthesis studies may result in more information losses than gains, thereby obliging researchers to find ways to preserve findings that are potentially valuable for practice.

Ethical issues in medical research in the developing world: a report on a meeting organised by Fondation Mérieux.

PubMed

Perrey, Christophe; Wassenaar, Douglas; Gilchrist, Shawn; Ivanoff, Bernard

2009-08-01

This paper reports on a multidisciplinary meeting held to discuss ethical issues in medical research in the developing world. Many studies, including clinical trials, are conducted in developing countries with a high burden of disease. Conditions under which this research is conducted vary because of differences in culture, public health, political, legal and social contexts specific to these countries. Research practices, including standards of care for participants, may vary as a result. It is therefore not surprising that ethical issues emerge. This meeting sought to identify and discuss these issues from the perspectives of the many actors in such research, including community representatives, with a view to finding ethical and pragmatic solutions to these issues. Dialogue between these actors was also promoted, with a view to identifying the need to develop such dialogue in future. Drawing from the experiences of the speakers, the colloquium attempted to outline some answers to several key questions characterising the field today. Experiences related to epidemiologic research, vaccine trials, drug trials, diagnostic tests and to some fundamental ethical issues in health research. Speakers were from different countries, disciplines and professions. The meeting provided a forum for consultation and debate between different ethics actors. Both encouraging findings and challenges emerged.

The aim of this study was to explore the information flow of hospice interdisciplinary meetings focusing on information access, exchange and documentation. The study participants were members of four hospice interdisciplinary teams in the Midwestern United States. Team members included a diverse range of professionals including physicians, nurses, social workers, bereavement counselors, and others. A total of 81 patient care discussions were videotaped and transcribed. A content analysis revealed several themes that needed to be addressed to improve the overall information flow, such as access to and recording of information, documentation of services, obtaining information from absent team members, data redundancy and updating of recorded information. On average, 5% of all utterances when discussing a patient case were focused on soliciting information from the member who had access to the patient chart. In 12.3% of all discussions, members referred to an absent member who could have provided additional information. In 8.6% of all discussions the same facts were repeated three times or more. Based on the findings we propose guidelines that can address potential informational gaps and enhance team communication in hospice. PMID:19012142

Economic abuse in Lebanon: experiences and perceptions.

PubMed

Usta, Jinan; Makarem, Nisrine N; Habib, Rima R

2013-03-01

This article explores the experiences and perceptions of Lebanese women and men with economic abuse. Data were drawn from focus group discussions and face-to-face interviews with men, women and social workers. The findings reveal that Lebanese women experience many forms of economic abuse, including the withholding of earnings, restricted involvement in the labor force, and limited purchasing decisions. Inheritance laws and practices still favor men over women. Women tolerate economic abuse to avoid more serious forms of abuse and ensure family stability. Practical implications of the findings are presented.

Experimental game theory and behavior genetics.

PubMed

Cesarini, David; Dawes, Christopher T; Johannesson, Magnus; Lichtenstein, Paul; Wallace, Björn

2009-06-01

We summarize the findings from a research program studying the heritability of behavior in a number of widely used economic games, including trust, dictator, and ultimatum games. Results from the standard behavior genetic variance decomposition suggest that strategies and fundamental economic preference parameters are moderately heritable, with estimates ranging from 18 to 42%. In addition, we also report new evidence on so-called "hyperfair" preferences in the ultimatum game. We discuss the implications of our findings with special reference to current efforts that seek to understand the molecular genetic architecture of complex social behaviors.

Authoritative parenting and drug-prevention practices: implications for antidrug ads for parents.

PubMed

Stephenson, Michael T; Quick, Brian L; Atkinson, Joshua; Tschida, David A

2005-01-01

This research employed the theory of reasoned action to investigate the role of authoritative parenting in 3 drug-prevention behaviors: (a) parental monitoring, (b) parent-child discussions, and (c) awareness of the child's environment. A phone survey of 158 parents of adolescents in 7th, 9th, and 11th grades revealed that authoritative parenting was correlated with parenting practices that reduce the likelihood of adolescent drug use, including discussing family rules about drugs, discussing strategies to avoid drugs, discussing those in trouble with drugs, parental monitoring, knowing the child's plans for the coming day, and personally knowing the child's friends well. Additionally, authoritative parenting moderated the attitude-behavioral intention relation for parental monitoring and awareness of the child's environment, with the weakest relation detected for low-authoritative parents. The utility of these findings in helping design and target antidrug messages for parents more effectively is discussed.

Opportunities During Early Life for Cancer Prevention: Highlights From a Series of Virtual Meetings With Experts

PubMed Central

Holman, Dawn M.; Buchanan, Natasha D.

2018-01-01

Compelling evidence suggests that early life exposures can affect lifetime cancer risk. In 2014, the Centers for Disease Control and Prevention’s (CDC’s) Cancer Prevention Across the Lifespan Workgroup hosted a series of virtual meetings with select experts to discuss the state of the evidence linking factors during the prenatal period and early childhood to subsequent risk of both pediatric and adult cancers. In this article, we present the results from a qualitative analysis of the meeting transcripts and summarize themes that emerged from our discussions with meeting participants. Themes included the state of the evidence linking early life factors to cancer risk, research gaps and challenges, the level of evidence needed to support taking public health action, and the challenges of communicating complex, and sometimes conflicting, scientific findings to the public. Opportunities for collaboration among public health agencies and other stakeholders were identified during these discussions. Potential next steps for the CDC and its partners included advancing and building upon epidemiology and surveillance work, developing and using evidence from multiple sources to inform decision-making, disseminating and communicating research findings in a clear and effective way, and expanding collaborations with grantees and other partners. As the science on early life factors and cancer risk continues to evolve, there are opportunities for collaboration to translate science into actionable public health practice. PMID:27940972

2014-01-01

This paper describes the methods and key findings of formative research conducted to design a school-based program for obesity prevention. Formative research was based on the ecological model and the principles of social marketing. A mixed method approach was used. Qualitative (direct observation, indepth interviews, focus group discussions and photo-voice) and quantitative (closed ended surveys, checklists, anthropometry) methods were employed. Formative research key findings, including barriers by levels of the ecological model, were used for designing a program including environmental strategies to discourage the consumption of energy dense foods and sugar beverages. Formative research was fundamental to developing a context specific obesity prevention program in schools that seeks environment modification and behavior change.

Potential integrated applications are investigated and an initial list is provided including consumer services, travel, law enforcement, human resources, marketing, and education and training.

Medical retirement from sport after concussions

PubMed Central

Davis-Hayes, Cecilia; Baker, David R.; Bottiglieri, Thomas S.; Levine, William N.; Desai, Natasha; Gossett, James D.

2018-01-01

Purpose of review In patients with a considerable history of sports-related concussion, the decision of when to discontinue participation in sports due to medical concerns including neurologic disorders has potentially life-altering consequences, especially for young athletes, and merits a comprehensive evaluation involving nuanced discussion. Few resources exist to aid the sports medicine provider. Recent findings In this narrative review, we describe 10 prototypical vignettes based upon the authors' collective experience in concussion management and propose an algorithm to help clinicians navigate retirement discussions. Issues for consideration include absolute and relative contraindications to return to sport, ranging from clinical or radiographic evidence of lasting neurologic injury to prolonged concussion recovery periods or reduced injury threshold to patient-centered factors including personal identity through sport, financial motivations, and navigating uncertainty in the context of long-term risks. Summary The authors propose a novel treatment algorithm based on real patient cases to guide medical retirement decisions after concussion in sport. PMID:29517059

2016-01-01

Parents play a critical role in shaping their children's substance use behaviors, yet few studies have examined the messages that caregivers give their adolescents about tobacco. In this study, we identify tobacco-related messages discussed by African American maternal caregivers and their adolescent daughters. Twenty-five African American maternal caregivers and their adolescent daughters participated in a video-taped discussion about tobacco. Discussions were transcribed and coded thematically. Seven themes emerged, which were grouped into tobacco-messages and communication strategies. Messages included health risks, non-health-related reasons to stop smoking, reasons people smoke, and tobacco products and marijuana. Strategies caregivers used to communicate their tobacco-related messages included sharing personal or their families' experience with smoking, using humor, and role-playing. Finally, embedded within all of the themes, participants expressed their disapproval of tobacco use, whether it was directed at their own use, their adolescents' use, a family members' use, or peers' use. African American maternal caregivers and their daughters openly talk about a variety of tobacco-related topics, and caregivers are open to sharing their own and their families' experience with substance use. Findings also suggest that having caregivers and their adolescents participate in discussions tasks could be potentially beneficial in facilitating discussions and could identify areas in which caregivers could use help in discussing sensitive topics.

2017-02-01

Medical and research professionals who discuss clinical trials and research studies with potential participants face an often daunting challenge, particularly when recruiting from minority and underserved populations. This study reports on findings from a focus group study of 63 research coordinators, study nurses, professional recruiters, and other professionals in Indianapolis, IN and Miami, FL who work to recruit from minority and underserved populations. These professionals discussed the importance of creating a sense of connection with potential participants as part of the recruitment and retention process. Building a relationship, however fleeting, involved a number of concrete behaviors, including listening to personal information, expressing empathy, and then providing reciprocal self-disclosures; having repeated contact, usually by working in the same environment over an extended period of time; demonstrating respect through politeness and the use of honorifics; going the extra mile for participants; offering flexibility in scheduling follow-up appointments; and creating a sense of personal and community trust by being truthful. The implications of these findings for clinical trial and research study accrual are discussed.

2014-03-01

Community-based participatory research (CBPR) is an important framework for partnering with communities to reduce health disparities. Working in partnership with community incurs additional costs, some that can be represented in a budget summary page and others that are tied to the competing demands placed on community and academic partners. These cost considerations can inform development of community-academic partnerships. We calculated costs from a case study based on an ongoing CBPR project involving a Community Planning Group (CPG) of community co-researchers in rural Alaska and a bicultural liaison group who help bridge communication between CPG and academic co-researchers. Budget considerations specific to CBPR include travel and other communication-related costs, compensation for community partners, and food served at meetings. We also identified sources of competing demands for community and academic partners. Our findings can inform budget discussions in community-academic partnerships. Discussions of competing demands on community partners' time can help plan timelines for CBPR projects. Our findings may also inform discussions about tenure and promotion policies that may represent barriers to participation in CBPR for academic researchers.

2014-12-01

To describe an intervention promoting benefit-finding in Alzheimer caregivers, to discuss key issues in implementation and ways to resolve them, and to examine whether the intervention reduced burden and depression in a small randomized trial. Twenty-five caregivers were randomized into benefit-finding and psychoeducation groups. Both groups had eight weekly sessions. Outcome measures including role overload, Zarit Burden Interview, and Hamilton depression scale were collected at baseline and after treatment. Results were analyzed using analysis of covariance. Additionally, the challenges of implementing such interventions, some of which related to cultural issues, were analyzed qualitatively. Controlling for pretest, the benefit-finding group had lower depression than the psychoeducation group at post-test, despite the fact that some caregivers found benefit-finding challenging. The two groups did not differ on overload and burden. However, within-group analysis suggested that both groups showed significant reductions in overload from pretest to post-test. In addition, we discussed participants' difficulties in grasping the technique of thought modification for benefit-finding, recording such exercises at home, and sharing their thoughts and experiences in groups. We described measures undertaken in the main trial to overcome these issues. Cognitive approaches focusing on benefit-finding are feasible among Chinese caregivers, with preliminary evidence suggesting an effect on alleviating depression. © The Author 2014.

Talking Science: The research evidence on the use of small group discussions in science teaching

NASA Astrophysics Data System (ADS)

Bennett, Judith; Hogarth, Sylvia; Lubben, Fred; Campbell, Bob; Robinson, Alison

2010-01-01

This paper reports the findings of two systematic reviews of the use and effects of small group discussions in high school science teaching. Ninety-four studies were included in an overview (systematic map) of work in the area, and 24 studies formed the basis of the in-depth reviews. The reviews indicate that there is considerable diversity in the topics used to promote small group discussions. They also demonstrate that students often struggle to formulate and express coherent arguments, and demonstrate a low level of engagement with tasks. The reviews suggest that groups function more purposefully, and understanding improves most, when specifically constituted such that differing views are represented, when some form of training is provided for students on effective group work, and when help in structuring discussions is provided in the form of "cues". Single-sex groups function more purposefully than mixed-sex groups, though improvements in understanding are independent of gender composition of groups. Finally, the reviews demonstrate very clearly that, for small group discussions to be effective, teachers and students need to be given explicit teaching in the skills associated with the development of arguments and the characteristics associated with effective group discussions. In addition to the substantive findings, the paper also reports on key features of the methods employed to gather and analyse data. Of particular note are the two contrasting approaches to data analysis, one adopting a grounded theory approach and the other drawing on established methods of discourse analysis.

Please Ask Gently: Using Culturally Targeted Communication Strategies to Initiate End-of-Life Care Discussions With Older Chinese Americans.

2018-01-01

Health-care providers (HCPs) find facilitating end-of-life (EOL) care discussions challenging, especially with patients whose ethnicities differ from their own. Currently, there is little guidance on how to initiate and facilitate such discussions with older Chinese Americans (≥55 years) and their families. To explore communication strategies for HCPs to initiate EOL care discussions with older Chinese Americans in the San Francisco Bay Area. This qualitative (focused) ethnographic study included field observations and individual semistructured interviews with 14 community-dwelling older Chinese Americans who lived independently at home, 9 adult children, and 7 HCPs. Responses were analyzed using open coding, memos, and comparison across participants. The study participants emphasized the importance of assessing readiness for early EOL care discussions. All recommended using indirect communication approaches to determine older Chinese Americans' readiness. Indirect communication can be culturally targeted and applied at both system-wide (ie, health-care system) and individual (ie, HCP) levels. To institutionalize the practice, health-care facilities should implement EOL care discussion inquiries as part of routine during check-in or intake questionnaires. In individual practice, using depersonalized communication strategies to initiate the discussion was recommended to determine older Chinese Americans' readiness. Assessing readiness should be an essential and necessary action for early EOL care discussions. Culturally targeted assessment of older Chinese Americans includes using indirect communication approaches to initiate an EOL care discussion to determine their readiness. In addition to health-care system integration, providers should implement and evaluate proposed EOL discussion initiation prompts with their older Chinese American patients.

Preparedness to initiate end-of-life (EoL) discussions is a confronting and daunting task for all healthcare professionals. We conducted a group interview to explore healthcare professionals' experiences of preparing for EoL discussions with the patient and their family in a pediatric context. To identify what pediatric healthcare professionals consider important when preparing for an EoL discussion. A qualitative design using a group interview. Two open-ended questions were asked: (1) How could preparedness to initiate EoL care discussions between healthcare professionals and the patient and family be enhanced? (2) What education resources/strategies could be developed to support preparation for EoL care discussions? Healthcare professionals, including medical, nursing, and allied health professionals working in pediatric palliative care settings across Queensland, Australia. These settings included major tertiary hospitals, general practice, community, and nongovernment organizations. A convenience sample of 36 healthcare professionals consented to participate in the study. An analysis of the data identified seven themes that had relevance for preparing for an EoL discussion: communication, healthcare professional perspectives, interdisciplinary team role, patient and family perspectives, practical issues, addressing mistakes, and healthcare professional education. Pediatric healthcare professionals confirmed that gaps exist in preparing for an EoL discussion. The findings support a need for further research in two areas. First, a systematic review of interdisciplinary resources that are available to support healthcare professionals in preparing for EoL discussions is recommended. Second, evidence-based interdisciplinary interventions to support pediatric EoL discussions need to be developed and evaluated.

ABSTRACTIt is critical to ensure that long-term care (LTC) homes are sensitive to the needs of lesbian, gay, bisexual, and transgender (LGBT) older adults. However, the extent to which the LTC home sector has adopted recommended strategies is unknown. This qualitative study reports findings from two initiatives: Semi-structured telephone interviews with Canadian LTC home administrators on strategies adopted to support LGBT inclusivity (n = 32), and discussions with participants attending a 2-day meeting on supporting LGBT inclusivity in LTC (n = 25). We found that LGBT inclusivity training was the most commonly adopted strategy among the LTC homes surveyed. Study findings further suggested that practices more visible to residents and families, such as LGBT-themed programming, inclusive language and symbols, or joint initiatives with LGBT communities, were less commonly adopted because of anticipated negative resident/family reactions. The importance and benefits of comprehensive strategies that include staff, residents, and family are discussed.

The Portevin–Le Chatelier effect: a review of experimental findings

PubMed Central

Yilmaz, Ahmet

2011-01-01

The Portevin–Le Chatelier (PLC) effect manifests itself as an unstable plastic flow during tensile tests of some dilute alloys under certain regimes of strain rate and temperature. The plastic strain becomes localized in the form of bands which move along a specimen gauge in various ways as the PLC effect occurs. Because the localization of strain causes degradation of the inherent structural properties and surface quality of materials, understanding the effect is crucial for the effective use of alloys. The characteristic behaviors of localized strain bands and techniques commonly used to study the PLC effect are summarized in this review. A brief overview of experimental findings, the effect of material properties and test parameters on the PLC effect, and some discussion on the mechanisms of the effect are included. Tests for predicting the early failure of structural materials due to embrittlement induced by the PLC effect are also discussed. PMID:27877450

Inclusion of Children With Disabilities in Physical Education: A Systematic Review of Literature From 2009 to 2015.

PubMed

Wilhelmsen, Terese; Sørensen, Marit

2017-07-01

This systematic review examines research published from 2009 to 2015 on inclusion of children with disabilities in physical education according to the PRISMA guidelines. We have used a stakeholder approach as a framework for organizing and discussing the results. The searches yielded 535 studies, of which 112 were included. The systematic review outlines which stakeholder perspectives received the most attention, the main themes and findings, the methodological trends that governed the research contribution, and the country of data collection. The main findings indicated that perspectives of pre- and in-service teachers and studies of attitudes still dominate the research contributions. The strengths and limitations of the research conducted to date highlight that several other perspectives need to be discussed. Especially important is seeking information from children with disabilities themselves. Other barriers and facilitators perceived by those actively involved in the inclusion process need to be sought.

2017-03-01

To date, attention to the environmental production of disability among older adults with age-related vision loss (ARVL) has been limited. This critical ethnographic study aimed to reveal the ways in which environmental barriers produced and perpetuated disability for 10 older adults with ARVL. A modified version of Carspecken's five-stage approach for critical ethnography was adopted with three methods of data collection used, including a narrative interview, a participant observation session, and a semi-structured, in-depth interview. Findings revealed how disability is shaped for older adults with ARVL when they encounter environmental features that are embedded within an ageist and disablist society. These findings are illustrated via presenting analysis of three commonly discussed activities: shopping, eating, and community mobility. Our discussion suggests that addressing the environmental production of disability requires inclusive social policy, advocacy, and a focus on education in order to develop and sustain age and low-vision-friendly environments.

Religion, health and medicine in African Americans: implications for physicians.

PubMed

Levin, Jeff; Chatters, Linda M; Taylor, Robert Joseph

2005-02-01

Recent years have seen a burgeoning of research and writing on the connections between religion and health. The very best of this work comes from epidemiologic studies of African Americans. This paper summarizes results of these investigations, including findings identifying effects of religious participation on both physical and mental health outcomes. Evidence mostly supports a protective religious effect on morbidity and mortality and on depressive symptoms and overall psychological distress among African Americans. This paper also carefully discusses what the results of these studies mean and do not mean, an important consideration due to frequent misinterpretations of findings on this topic. Because important distinctions between epidemiologic and clinical studies tend to get glossed over, reports of religion-health associations oftentimes draw erroneous conclusions that foster unrealistic expectations about the role of faith and spirituality in health and healing. Finally, implications are discussed for clinical practice, medical education and public health.

Imaging sensors and readout electronics have made tremendous strides in the past two decades. The application of modern semiconductor fabrication techniques and the introduction of customized monolithic integrated circuits have made large-scale imaging systems routine in high-energy physics. This technology is now finding its way into other areas, such as space missions, synchrotron light sources, and medical imaging. I review current developments and discuss the promise and limits of new technologies. Several detector systems are described as examples of future trends. The discussion emphasizes semiconductor detector systems, but I also include recent developments for large-scale superconducting detector arrays.

Parent–Child Aggression Risk in Expectant Mothers and Fathers: A Multimethod Theoretical Approach

PubMed Central

Smith, Tamika L.; Silvia, Paul J.

2016-01-01

The current investigation evaluated whether cognitive processes characteristic of the Social Information Processing model predicted parent-child aggression (PCA) risk independent of personal vulnerabilities and resiliencies. This study utilized a multimethod approach, including analog tasks, with a diverse sample of 203 primiparous expectant mothers and 151 of their partners. Factors considered in this study included PCA approval attitudes, empathy, reactivity, negative child attributions, compliance expectations, and knowledge of non-physical discipline alternatives; additionally, vulnerabilities included psychopathology symptoms, domestic violence victimization, and substance use, whereas resiliencies included perceived social support, partner relationship satisfaction, and coping efficacy. For both mothers and fathers, findings supported the role of greater approval of PCA attitudes, lower empathy, more overreactivity, more negative attributions, and higher compliance expectations in relation to elevated risk of PCA. Moreover, personal vulnerabilities and resiliencies related to PCA risk for mothers; however, fathers and mothers differed on the nature of these relationships with respect to vulnerabilities as well as aspects of empathy and PCA approval attitudes. Findings provide evidence for commonalities in many of the factors investigated between mothers and fathers with some notable distinctions. Results are discussed in terms of how findings could inform prevention programs. PMID:28082826

1992-01-01

Discussions from a workshop to guide UCLA and NASA investigators on the state of knowledge and perceived needs in spacecraft fire safety and its risk management are reviewed, for an introduction to an analytical and experimental project in this field. The report summarizes the workshop discussions and includes the visual aids used in the presentations. Probabilistic Safety Assessment (PSA) methods, which are currently not used, would be of great value to the designs and operation of future human-crew spacecraft. Key points in the discussions were the importance of understanding and testing smoldering as a likely fire scenario in space and the need for smoke damage modeling, since many fire-risk models ignore this mechanism and consider only heat damage.

Manual handling of highway kerbs--focus group findings.

PubMed

Bust, P D; Gibb, A G F; Haslam, R A

2005-07-01

The manual handling of concrete highway kerbs remains commonplace in the construction industry despite obvious risks to operatives. This study was undertaken to find out why kerb installation still includes manual handling, to identify the alternatives that exist and to consider how the organisation of the work affects exposure to risk. Focus groups were held with industry professionals to discuss kerb design, installation and the training of operatives, with site visits and interviews undertaken to place the focus group findings in context. The focus group discussions highlighted manufacturer's "myopia", a lack of installation knowledge of designers and shortfalls in training for installation work. It was concluded that risks to the health of construction workers remain as they are not considered in the design of the product, design of the work or ameliorated by adequate risk assessment. Recommendations from the research are that a pro-active approach to health needs to be adopted by the manufacturers of heavy construction products. Designers of work requiring the use of heavy products need to have more experience of site operations, and education and training in manual handling is desirable at all levels in construction organisations.

Can stories reduce abortion stigma? Findings from a longitudinal cohort study.

PubMed

Cockrill, Kate; Biggs, Antonia

2018-03-01

Women often hide or selectively disclose abortion experiences due to stigma. Secrecy can help women avoid stigma but may also result in isolation and a lack of social support and contribute to broader social silence. This study assesses whether a book-club intervention can support abortion disclosure among book club participants and improve participants' affective responses towards women who have abortions and abortion providers. A total of 109 women from 13 all-female book clubs located in 9 US states read and discussed a non-fiction book that included stories about pregnancy and abortion, participated in a book club discussion and completed baseline, immediate post-intervention and endline surveys. In 10 out of the 13 book club discussions, at least one member disclosed having had a previous abortion. Overall, 15 of the 19 women who privately reported having a previous abortion self-disclosed one or more abortions during the book club discussion. Following the book club intervention, women reported having more positive feelings toward women who have abortions and abortion providers. Greater improvement and longer lasting effects were seen in groups where there was also an in-person disclosure of abortion experience. Findings suggest that exposure to the stories of women who have had abortions can reduce abortion stigma.

Inclusive Discourse? Local Media Coverage of the Terri Schiavo Case

PubMed Central

Rohlinger, Deana A.; Pederson, JoEllen; Valle, Giuseppina

2015-01-01

This article contributes to a more systematic understanding of the role of mainstream media in deliberative processes by analyzing how inclusive local newspapers are of diverse perspectives on the Terri Schiavo case. Using both Pearson’s chi-square test and multinomial logistic regression, we assess how ownership, state political ideology, geographic location, and news format affect what ideas are included in the debate over whether Terri Schiavo’s hydration and nutrition tubes should be removed as well as the tone with which these ideas are discussed. We find that mainstream newspapers are relatively inclusive of diverse ideas and perspectives—regardless of whether the newspaper is independently or corporately owned, the political leanings of the target audience, and the geographic location of the outlet. However, we also find that local newspapers do significantly differ from one another in terms of the frequency and tone with which they include diverse viewpoints. Our research suggests that local outlets downplay ideas that are likely to be regarded as controversial by their target audiences. We conclude with a discussion of the implications of this research for understanding the role of media in deliberative democratic processes in the United States. PMID:26120237

Fifth IPCC Assessment Report Now Out

Kundzewicz, Zbigniew W.

2014-01-01

The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) is now available. It provides policymakers with an assessment of information on climate change, its impacts and possible response options (adaptation and mitigation). Summaries for policymakers of three reports of IPCC working groups and of the Synthesis Report have now been approved by IPCC plenaries. This present paper reports on the most essential findings in AR5. It briefly informs on the contents of reports of all IPCC working groups. It discusses the physical science findings, therein observed changes (ubiquitous warming, shrinking cryosphere, sea level rise, changes in precipitation and extremes, and biogeochemical cycles). It deals with the drivers of climate change, progress in climate system understanding (evaluation of climate models, quantification of climate system responses), and projections for the future. It reviews impacts, adaptation and vulnerability, including observed changes, key risks, key reasons for concern, sectors and systems, and managing risks and building resilience. Finally, mitigation of climate change is discussed, including greenhouse gas emissions in the past, present and future, and mitigation in sectors. It is hoped that the present article will encourage the readership of this journal to dive into the AR5 report that provides a wealth of useful information.

Chloroplast evolution, structure and functions

Jensen, Poul Erik

2014-01-01

In this review, we consider a selection of recent advances in chloroplast biology. These include new findings concerning chloroplast evolution, such as the identification of Chlamydiae as a third partner in primary endosymbiosis, a second instance of primary endosymbiosis represented by the chromatophores found in amoebae of the genus Paulinella, and a new explanation for the longevity of captured chloroplasts (kleptoplasts) in sacoglossan sea slugs. The controversy surrounding the three-dimensional structure of grana, its recent resolution by tomographic analyses, and the role of the CURVATURE THYLAKOID1 (CURT1) proteins in supporting grana formation are also discussed. We also present an updated inventory of photosynthetic proteins and the factors involved in the assembly of thylakoid multiprotein complexes, and evaluate findings that reveal that cyclic electron flow involves NADPH dehydrogenase (NDH)- and PGRL1/PGR5-dependent pathways, both of which receive electrons from ferredoxin. Other topics covered in this review include new protein components of nucleoids, an updated inventory of the chloroplast proteome, new enzymes in chlorophyll biosynthesis and new candidate messengers in retrograde signaling. Finally, we discuss the first successful synthetic biology approaches that resulted in chloroplasts in which electrons from the photosynthetic light reactions are fed to enzymes derived from secondary metabolism.

Income inequality, drug-related arrests, and the health of people who inject drugs: Reflections on seventeen years of research

2017-01-01

This paper reviews and then discusses selected findings from a seventeen year study about the population prevalence of people who inject drugs (PWID) and of HIV prevalence and mortality among PWID in 96 large US metropolitan areas. Unlike most research, this study was conducted with the metropolitan area as the level of analysis. It found that metropolitan area measures of income inequality and of structural racism predicted all of these outcomes, and that rates of arrest for heroin and/or cocaine predicted HIV prevalence and mortality but did not predict changes in PWID population prevalence. Income inequality and measures of structural racism were associated with hard drug arrests or other properties of policing. These findings, whose limitations and implications for further research are discussed, suggest that efforts to respond to HIV and to drug injection should include supra-individual efforts to reduce both income inequality and racism. At a time when major social movements in many countries are trying to reduce inequality, racism and oppression (including reforming drug laws), these macro-social issues in public health should be both addressable and a priority in both research and action.

2014-09-01

Recent findings related to childhood leukaemia incidence near nuclear installations have raised questions which can be answered neither by current knowledge on radiation risk nor by other established risk factors. In 2012, a workshop was organised on this topic with two objectives: (a) review of results and discussion of methodological limitations of studies near nuclear installations; (b) identification of directions for future research into the causes and pathogenesis of childhood leukaemia. The workshop gathered 42 participants from different disciplines, extending widely outside of the radiation protection field. Regarding the proximity of nuclear installations, the need for continuous surveillance of childhood leukaemia incidence was highlighted, including a better characterisation of the local population. The creation of collaborative working groups was recommended for consistency in methodologies and the possibility of combining data for future analyses. Regarding the causes of childhood leukaemia, major fields of research were discussed (environmental risk factors, genetics, infections, immunity, stem cells, experimental research). The need for multidisciplinary collaboration in developing research activities was underlined, including the prevalence of potential predisposition markers and investigating further the infectious aetiology hypothesis. Animal studies and genetic/epigenetic approaches appear of great interest. Routes for future research were pointed out.

Seniors' online communities: a quantitative content analysis.

Nimrod, Galit

2010-06-01

To examine the contents and characteristics of seniors' online communities and to explore their potential benefits to older adults. Quantitative content analysis of a full year's data from 14 leading online communities using a novel computerized system. The overall database included 686,283 messages. There was a constant increase in the daily activity level during the research period. Content analysis identified 13 main subjects discussed in the communities, including (in descending order) "Fun on line," "Retirement," "Family," "Health," "Work and Study," "Recreation" "Finance," "Religion and Spirituality," "Technology," "Aging," "Civic and Social," "Shopping," and "Travels." The overall tone was somewhat more positive than negative. The findings suggest that the utilities of Information and Communications Technologies for older adults that were identified in previous research are valid for seniors' online communities as well. However, the findings suggest several other possible benefits, which may be available only to online communities. The communities may provide social support, contribute to self-preservation, and serve as an opportunity for self-discovery and growth. Because they offer both leisure activity and an expanded social network, it is suggested that active participation in the communities may contribute to the well-being of older adults. Directions for future research and applied implications are further discussed.

These include key features of the distributions that are not anticipated in the “bottom-up” thermalization scenario.

How to reduce scientific irreproducibility: the 5-year reflection.

PubMed

Fiala, Clare; Diamandis, Eleftherios P

2017-10-26

We discuss in depth six causes of scientific irreproducibility and their ramifications for the clinical sciences: fraud, unfounded papers published by prominent authorities, bias, technical deficiencies, fragmented science and problems with big data. Some proposed methods to combat this problem are briefly described, including an effort to replicate results from some high impact papers and a proposal that authors include detailed preclinical data in papers with supposedly high translational value. We here advocate for a 5-year reflection on papers with seemingly high clinical/translational potential, published alongside the original paper where authors reflect on the quality, reproducibility and impact of their findings. These reflections can be used as a benchmark for credibility, and begin a virtuous cycle of improving the quality of published findings in the literature.

Neuromuscular Ultrasound in the Assessment of Polyneuropathies and Motor Neuron Disease

Shen, Jack; Cartwright, Michael S.

2015-01-01

Neuromuscular ultrasound is an emerging technology for the evaluation of conditions affecting nerve and muscle, with the majority of research focusing on focal neuropathies. Despite this focus, researchers have also investigated the ultrasonographic changes that occur in the nerves and muscles of those with more diffuse polyneuropathies and motor neuron diseases, and this review will detail the findings in these conditions. Specific findings are discussed in this paper, but general themes will also be presented and include the following: hereditary polyneuropathies show diffuse nerve enlargement whereas immune-mediated polyneuropathies show more patchy involvement; nerve enlargement is more profound in demyelinating than axonal polyneuropathies; and muscle changes in motor neuron diseases include heterogeneous increases in echogenicity, atrophy, readily detectable fasciculations, and increased subcutaneous tissue thickness.

In this article we analyze qualitative data from a multiple methods, longitudinal study drawn from 15-year follow-up interviews with a subsample of 82 individuals arrested for driving while intoxicated in a southwestern state (1989–1995). We explore reactions to the arrest and court-mandated sanctions, including legal punishments, mandated interventions, and/or participation in programs aimed at reducing recidivism. Key findings include experiencing certain negative emotional reactions to the arrest, reactions to being jailed, experiencing other court-related sanctions as deterring driving while intoxicated behavior, and generally negative opinions regarding court-mandated interventions. We discuss interviewees’ complex perspectives on treatment and program participation and their effects on lessening recidivism, and we offer suggestions for reducing recidivism based on our findings.

Dadgar, Elham; Janati, Ali; Tabrizi, Jafar Sadegh; Asghari-Jafarabadi, Mohammad; Barati, Omid

2012-01-01

Background: Managers in the hospital should have enough managerial skill to be coordinated with the complex environment. Defining a competency framework assessment for hospital man-agement will help to establish core competencies for hospital managers. The aim of this study was to develop concrete and suitable performance assessment criteria using expert's view. Methods: In this qualitative study in total, 20 professionals participated in the interview and Fo¬cus Group Discussions (FGD). Two of informants were interviewed and 18 professionals par¬ticipants in three focus group discussions. Discussions and interviews were well planned, the FGD environments were suitable and after interviews completion the notes were checked with participant for completeness. Thematic analysis method was used for the analysis of qualitative data. Results: Findings from 3 FGDs and 2 semi structured interviews done with 20 professionals were categorized accordance to themes. The findings were classified in 7 major and 41 sub themes. The major themes include competency related to planning, organization and staff per-formance management, leadership, information management, and clinical governance and per-formance indicators. Conclusion: All participants had hospital administration experience; so their explanation impor¬tant in identifying the criteria and developing hospital managers’ performance assessment tool. In addition to professional perspectives and studies done in other countries, in order to design this kind of tools, it is necessary to adopt the obtained findings to the local hospital conditions.

Locus of the apices of projectile trajectories under constant drag

NASA Astrophysics Data System (ADS)

Hernández-Saldaña, H.

2017-11-01

Using the hodograph method, we present an analytical solution for projectile coplanar motion under constant drag, parametrised by the velocity angle. We find the locus formed by the apices of the projectile trajectories, and discuss its implementation for the motion of a particle on an inclined plane in presence of Coulomb friction. The range and time of flight are obtained numerically, and we find that the optimal launching angle is smaller than in the drag-free case. This is a good example of a problem with constant dissipation of energy that includes curvature; it is appropriate for intermediate courses of mechanics.

In this thesis, we first discuss the fundamentals of ab initio electronic structure theory and density functional theory (DFT). We also discuss statistics related to computing thermodynamic averages of molecular dynamics (MD). We then use this theory to analyze and compare the structural, dynamical, and electronic properties of liquid water next to prototypical metals including platinum, graphite, and graphene. Our results are built on Born-Oppenheimer molecular dynamics (BOMD) generated using density functional theory (DFT) which explicitly include van der Waals (vdW) interactions within a first principles approach. All calculations reported use large simulation cells, allowing for an accurate treatment of the water-electrode interfaces. We have included vdW interactions through the use of the optB86b-vdW exchange correlation functional. Comparisons with the Perdew-Burke-Ernzerhof (PBE) exchange correlation functional are also shown. We find an initial peak, due to chemisorption, in the density profile of the liquid water-Pt interface not seen in the liquid water-graphite interface, liquid watergraphene interface, nor interfaces studied previously. To further investigate this chemisorption peak, we also report differences in the electronic structure of single water molecules on both Pt and graphite surfaces. We find that a covalent bond forms between the single water molecule and the platinum surface, but not between the single water molecule and the graphite surface. We also discuss the effects that defects and dopants in the graphite and graphene surfaces have on the structure and dynamics of liquid water. Lastly, we introduce artificial neural networks (ANNs), and demonstrate how they can be used to machine learn electronic structure calculations. As a proof of principle, we show the success of an ANN potential energy surfaces for a dimer molecule with a Lennard-Jones potential.

This study aims to understand the nature and significance of online lay discussions about e-cigarettes and mental illness. We systematically searched the website Reddit.com using keywords related to e-cigarettes and mental illness. We coded relevant posts into themes under the framework of motivations for and limitations of vaping for people with mental illness. The thematic analysis included 3263 comments from 133 discussion threads. Six themes were classified as motivations to vape for people with mental illness: Self-medication; Quitting smoking; Freedom and control; Hobby; Social connectedness; and Motivation from caregivers and online communities. The limitations of vaping included: Unsatisfactory substitute for cigarettes and psychiatric medicines; Drug interactions; Nicotine addiction; Risks of e-liquid; Practical difficulties and Cost. People with mental illness; and their carers; use online discussion boards like Reddit to discuss the benefits and limitations of e-cigarettes for people with mental illness. Both positive and negative views exist. Media platforms like Reddit may shape the opinions of stakeholders and generate lay expertise about contentious health topics such as e-cigarettes. These findings have implications for policy and practice concerning assisting smokers with mental illness to reduce their health risk through switching to e-cigarettes. PMID:28025516

Neurological complications of human immunodeficiency virus (HIV) infection are a public health problem despite the availability of active antiretroviral therapies. The neuropathogenesis of HIV infection revolves around a complex cascade of events that include viral infection and glial immune activation, monocyte-macrophage brain infiltration, and secretion of a host of viral and cellular inflammatory and neurotoxic molecules. Although there is evidence that HIV-infected drug abusers experience more severe neurological disease, the biological basis for this finding is unknown. A scientific workshop organized by the National Institute on Drug Abuse (NIDA) was held on March 23-24, 2006 to address this question. The goal of the meeting was to bring together basic science and clinical researchers who are experts in NeuroAIDS, glial immunity, drugs of abuse, and/or pharmacology in order to find new approaches to understanding interactions between drug abuse and neuroAIDS. The format of the meeting was designed to stimulate open discussion and forge new multidisciplinary research collaborations. This report includes transcripts of active discussions and short presentations from invited participants. The presentations were separated into sections that included: Glial Biology, Inflammation, and HIV; Pharmacology, Neurotoxicology, and Neuroprotection; NeuroAIDS and Virology; and Virus-Drug and Immune-Drug Interactions. Research priorities were identified.

"He will ask why the child gets sick so often": the gendered dynamics of intra-household bargaining over healthcare for children with fever in the Volta Region of Ghana.

This paper explores the gendered dynamics of intra-household bargaining around treatment seeking for children with fever revealed through two qualitative research studies in the Volta Region of Ghana, and discusses the influence of different gender and health discourses on the likely policy implications drawn from such findings. Methods used included focus group discussions, in-depth and critical incidence interviews, and Participatory Learning and Action methods. We found that treatment seeking behaviour for children was influenced by norms of decision-making power and 'ownership' of children, access to and control over resources to pay for treatment, norms of responsibility for payment, marital status, household living arrangements, and the quality of relationships between mothers, fathers and elders. However, the implications of these findings may be interpreted from different perspectives. Most studies that have considered gender in relation to malaria have done so within a narrow biomedical approach to health that focuses only on the outcomes of gender relations in terms of the (non-)utilisation of allopathic healthcare. However, we argue that a 'gender transformatory' approach, which aims to promote women's empowerment, needs to include but go beyond this model, to consider broader potential outcomes of intra-household bargaining for women's and men's interests, including their livelihoods and 'bargaining positions'.

Background. Chronic or persistent pain and disability following noncatastrophic “musculoskeletal” (MSK) trauma is a pervasive public health problem. Recent intervention trials have provided little evidence of benefit from several specific treatments for preventing chronic problems. Such findings may appear to argue against formal targeted intervention for MSK traumas. However, these negative findings may reflect a lack of understanding of the causal mechanisms underlying the transition from acute to chronic pain, rendering informed and objective treatment decisions difficult. The Canadian Institutes of Health Research (CIHR) Institute of Musculoskeletal Health and Arthritis (IMHA) has recently identified better understanding of causal mechanisms as one of three priority foci of their most recent strategic plan. Objectives. A 2-day invitation-only active participation workshop was held in March 2015 that included 30 academics, clinicians, and consumers with the purpose of identifying consensus research priorities in the field of trauma-related MSK pain and disability, prediction, and prevention. Methods. Conversations were recorded, explored thematically, and member-checked for accuracy. Results. From the discussions, 13 themes were generated that ranged from a focus on identifying causal mechanisms and models to challenges with funding and patient engagement. Discussion. Novel priorities included the inclusion of consumer groups in research from the early conceptualization and design stages and interdisciplinary longitudinal studies that include evaluation of integrated phenotypes and mechanisms.

The potential of controlled environment crop production in a lunar colony is discussed. Findings on the effects of optimal root-zone and aerial environments derived as part of the NASA CELSS project at Utah State are presented. The concept of growing wheat in optimal environment is discussed. It is suggested that genetic engineering might produce the ideal wheat cultivar for CELSS (about 100 mm in height with fewer leaves). The Utah State University hydroponic system is outlined and diagrams of the system and plant container construction are provided. Ratio of plant mass to solution mass, minimum root-zone volume, maintenance, and pH control are discussed. A comparison of liquid hydrophonic systems and lunar regoliths as substrates for plant growth is provided. The physiological processes that are affected by the root-zone environment are discussed including carbon partitioning, nutrient availability, nutrient absorption zones, root-zone oxygen, plant water potential, root-produced hormones, and rhizosphere pH control.

Regulatory RNAs and control of epigenetic mechanisms: expectations for cognition and cognitive dysfunction.

PubMed

Butler, Anderson A; Webb, William M; Lubin, Farah D

2016-01-01

The diverse functions of noncoding RNAs (ncRNAs) can influence virtually every aspect of the transcriptional process including epigenetic regulation of genes. In the CNS, regulatory RNA networks and epigenetic mechanisms have broad relevance to gene transcription changes involved in long-term memory formation and cognition. Thus, it is becoming increasingly clear that multiple classes of ncRNAs impact neuronal development, neuroplasticity, and cognition. Currently, a large gap exists in our knowledge of how ncRNAs facilitate epigenetic processes, and how this phenomenon affects cognitive function. In this review, we discuss recent findings highlighting a provocative role for ncRNAs including lncRNAs and piRNAs in the control of epigenetic mechanisms involved in cognitive function. Furthermore, we discuss the putative roles for these ncRNAs in cognitive disorders such as schizophrenia and Alzheimer's disease.

Perceptions of Successful Aging: Intergenerational Voices Value Well-Being.

PubMed

Kelly, Gina Aalgaard; Lazarus, Jennie

2015-03-01

This study explored the perceptions of successful aging from intergenerational perspectives. A total of 66 participants were interviewed from three different generations including college students, parents, and grandparents. After qualitative data collection and analyses were used, five conceptual categories emerged from the data that related to perceptions of successful aging. The five concepts include wisdom, health, financial stability, staying active, and well-being. Conceptual categories emerged from the participants of different generations, and some were interconnected across generations. Each category is representative of major thematic patterns. Well-being was the primary concept which emerged because all three generations perceived and explicitly discussed well-being as the most valued aspect of successful aging. Previous successful aging research informed the use of a bio-psycho-social theoretical lens to frame the study findings and discussion. © The Author(s) 2015.

2009-03-01

Early home literacy experiences, including parent-child book reading, account for a significant amount of childrens' later reading achievement. Yet, there is a very limited research base about the home literacy environments and experiences of children with cognitive disabilities. The purpose of this study is to describe findings from a web-based survey of home literacy environments of young children with Down syndrome. Respondents ( n = 107) were mostly mothers; a majority were well-educated. Findings suggest that respondents gave literacy a higher priority than reported in prior research on children with disabilities. Over 70% of respondents had 50 or more childrens' books and also had literacy materials including flashcards, magnetic letters, and educational videos or computer games. Most parents read to their children and used these literacy materials 10-30 minutes per day. Respondents reported that their children had reached many important early literacy milestones and they also described having relatively ambitious life-long literacy goals for their children. Important implications for research and practice are discussed.

This study sought to replicate Herbert et al. (2003a), which found increased overall white matter (WM) volume in subjects with autism, even after controlling for head size differences. To avoid the possibility that greater WM volume in autism is merely an epiphenomena of macrocephaly over-representation associated with the disorder, the current study included control subjects with benign macrocephaly. The control group also included subjects with a reading disability to insure cognitive heterogeneity. WM volume in autism was significantly larger, even when controlling for brain volume, rate of macrocephaly, and other demographic variables. Autism and controls differed little on whole-brain WM voxel-based morphometry (VBM) analyses suggesting that the overall increase in WM volume was non-localized. Autism subjects exhibited a differential pattern of IQ relationships with brain volumetry findings from controls. Current theories of brain overgrowth and their importance in the development of autism are discussed in the context of these findings. PMID:20446133

Does state boredom cause failures of attention? Examining the relations between trait boredom, state boredom, and sustained attention.

PubMed

Hunter, Andrew; Eastwood, John D

2016-08-10

Boredom is an important personal and social problem, but the phenomena itself remains poorly understood. Recent work has shown that boredom is highly related to attention, and that this relationship may be instrumental in revealing boredom's causes and consequences. In this paper, experimental findings on trait boredom, state boredom, and sustained attention performance are presented. We demonstrate that trait boredom uniquely predicts sustained attention performance, over and above depression and self-report attention problems. We also present exploratory findings consistent with the claim that attention failures may cause boredom and that sustained attention tasks may themselves be boring. Discussion of each of these findings, and potential ramifications for cognitive research as a whole, is included.

Ethnic identity and mentoring among Latinas in professional roles.

This study examined ethnic identity and mentoring (a known strategy to promote career success and advancement) in a sample of 103 Latina women with professional roles in the areas of business, academia, policy, and politics. Other variables examined included traditional gender roles and perceptions of professional success. Findings indicated that the women's ethnic identity was consistent with a bicultural profile; some received mentoring and, if given a choice, would prefer to be mentored by someone of similar ethnicity. This finding is critical and can allow researchers, service providers, and policy developers to apply culturally responsive strategies in communities and in organizations. Other hypotheses were not supported. A discussion of the findings, implications, and suggestions for future research are presented. (c) 2005 APA

The inclusion of genomic data in the electronic health record raises important ethical, legal, and social issues. In this article, we highlight these challenges and discuss potential solutions. We provide a brief background on the current state of electronic health records in the context of genomic medicine, discuss the importance of equitable access to genome-enabled electronic health records, and consider the potential use of electronic health records for improving genomic literacy in patients and providers. We highlight the importance of privacy, access, and security, and of determining which genomic information is included in the electronic health record. Finally, we discuss the challenges of reporting incidental findings, storing and reinterpreting genomic data, and nondocumentation and duty to warn family members at potential genetic risk.

Magnetospheric electric fields and currents

Mauk, B. H.; Zanetti, L. J.

1987-01-01

The progress made in the years 1983-1986 in understanding the character and operation of magnetospheric electric fields and electric currents is discussed, with emphasis placed on the connection with the interior regions. Special attention is given to determinations of global electric-field configurations, measurements of the response of magnetospheric particle populations to the electric-field configurations, and observations of the magnetospheric currents at high altitude and during northward IMF. Global simulations of current distributions are discussed, and the sources of global electric fields and currents are examined. The topics discussed in the area of impulsive and small-scale phenomena include substorm current systems, impulsive electric fields and associated currents, and field-aligned electrodynamics. A key finding of these studies is that the electric fields and currents are interrelated and cannot be viewed as separate entities.

Safety leadership and systems thinking: application and evaluation of a Risk Management Framework in the mining industry.

Donovan, Sarah-Louise; Salmon, Paul M; Lenné, Michael G; Horberry, Tim

2017-10-01

Safety leadership is an important factor in supporting safety in high-risk industries. This article contends that applying systems-thinking methods to examine safety leadership can support improved learning from incidents. A case study analysis was undertaken of a large-scale mining landslide incident in which no injuries or fatalities were incurred. A multi-method approach was adopted, in which the Critical Decision Method, Rasmussen's Risk Management Framework and Accimap method were applied to examine the safety leadership decisions and actions which enabled the safe outcome. The approach enabled Rasmussen's predictions regarding safety and performance to be examined in the safety leadership context, with findings demonstrating the distribution of safety leadership across leader and system levels, and the presence of vertical integration as key to supporting the successful safety outcome. In doing so, the findings also demonstrate the usefulness of applying systems-thinking methods to examine and learn from incidents in terms of what 'went right'. The implications, including future research directions, are discussed. Practitioner Summary: This paper presents a case study analysis, in which systems-thinking methods are applied to the examination of safety leadership decisions and actions during a large-scale mining landslide incident. The findings establish safety leadership as a systems phenomenon, and furthermore, demonstrate the usefulness of applying systems-thinking methods to learn from incidents in terms of what 'went right'. Implications, including future research directions, are discussed.

An Attentional Scope Model of Rumination

PubMed Central

Whitmer, Anson J.; Gotlib, Ian H.

2013-01-01

Rumination, defined as repetitive thinking about negative information, has been found to lead to serious maladaptive consequences, including longer and more severe episodes of major depression. In this review, we present and discuss research findings motivated by the formulation that individual differences in cognitive processes that control how information is processed influence the likelihood that thoughts will become repetitive and negative. A number of studies have demonstrated that a tendency to ruminate (i.e., trait rumination) is related to difficulties updating working memory (WM) and disengaging from and forgetting no-longer-relevant information. Other investigators have documented that trait rumination is also associated with an enhanced ability to ignore distracting information and to more stable maintenance of task-relevant information. In contrast to trait rumination, a state of rumination has been found to be related to widespread deficits in cognitive control. In this paper we discuss how the current accounts of control functioning cannot explain this pattern of anomalous control functioning. To explain these findings, including unexpected and contradictory results, we present an attentional scope model of rumination that posits that a constricted array of thoughts, percepts, and actions that are activated in WM or available for selection from LTM affects the control functioning of trait ruminators. This model explains, at a cognitive level, why rumination is particularly likely to arise when individuals are in a negative mood state; it also accounts for a number of findings outside of the rumination-control literature and generates several novel predictions.

Climate Change in Colorado: Findings and Scientific Challenges

Barsugli, J.; Ray, A.; Averyt, K.; Wolter, K.; Hoerling, M. P.

2008-12-01

In response to the risks associated with anthropogenic climate change, Governor Ritter issued the Colorado Climate Action Plan (CCAP) in 2007. In support of the adaptation component of the CCAP, the Colorado Water Conservation Board commissioned the Western Water Assessment at the University of Colorado to prepare the report "Climate Change in Colorado: A Synthesis to Support Water Resources Management and Adaptation." The objective of "Climate Change in Colorado" is to communicate the state of the science regarding the physical aspects of climate change that are important for evaluating impacts on Colorado's water resources. Accordingly, the document focuses on observed trends, modeling, attribution, and projections of hydroclimatic variables that are important for Colorado's water supply. Although many published datasets include information about Colorado, there are few climate studies that focus on the state. Consequently, many important analyses for Colorado are lacking. The report summarizes Colorado-specific findings from peer-reviewed regional studies, and presents new analyses derived from existing datasets. Here we will summarize the findings of the report, discuss the extent to which conclusions from West-wide studies hold in Colorado, and highlight the many scientific challenges that were faced in the preparation of the report. These challenges include interpreting observed and projected precipitation and temperature variability and trends, dealing with attribution and uncertainty at the state level, and justifying the relevance of climate model projections in a topographically complex state. A second presentation (Ray et al.) discusses the process of developing the report.

The resulting findings for the climate change impacts on these sectors are discussed in this presentation, with the effects on water resources discussed separately. Major findings include: Widespread climate-related impacts are occurring now and are expected to increase. Climate changes are already affecting water, energy, transportation, agriculture, ecosystems, and health. These impacts are different from region to region and will grow under projected climate change. Crop and livestock production will be increasingly challenged. Agriculture is considered one of the sectors most adaptable to changes in climate. However, increased heat, pests, water stress, diseases, and weather extremes will pose adaptation challenges for crop and livestock production. Coastal areas are at increasing risk from sea-level rise and storm surge. Sea-level rise and storm surge place many U.S. coastal areas at increasing risk. Energy and transportation infrastructure and other property in coastal areas are very likely to be adversely affected. Threats to human health will increase. Health impacts of climate change are related to heat stress, waterborne diseases, poor air quality, extreme weather events, and diseases transmitted by insects and rodents. Robust public health infrastructure can reduce the potential for negative impacts. Climate change will interact with many social and environmental stresses. Climate change will combine with pollution, population growth, overuse of resources, urbanization, and other social, economic, and environmental stresses to create larger impacts than from any of these factors alone. Thresholds will be crossed, leading to large changes in climate and ecosystems. There are a variety of thresholds in the climate system and ecosystems. These thresholds determine, for example, the presence of sea ice and permafrost, and the survival of species, from fish to insect pests, with implications for society. With further climate change, the crossing of additional thresholds is expected. These and many other findings will be discussed in the presentation.

Much research has been done on how people find their way from one place to another. Compared to that, there is less research available on how people find back from the destination to their origin. We first present theoretical approaches to perceptual and cognitive processes involved in finding a return path, including concepts, such as visibility, structural salience, and allocentric versus egocentric perspective, followed by a series of three experiments. In these experiments, we presented subjects intersections that contained landmark information on different positions. In order to investigate the processes involved, we used different measures, such as route-continuation (in learning direction and in opposite direction) and free-recall of route information. In summary, the results demonstrate the importance of landmark positions at intersections (structural salience in combination with perspective) and that finding the return path is more difficult than reproducing the same route from the learning condition. All findings will be discussed with respect to the current research literature on landmark-based wayfinding. PMID:28066283

Mortezavi, Mahta; Thiele, Ralph; Ritchlin, Christopher

2015-01-01

Psoriatic arthritis (PsA), a chronic inflammatory joint disease associated with psoriasis, is notable for diversity in disease presentation, course and response to treatment. Equally varied are the types of musculoskeletal involvement which include peripheral and axial joint disease, dactylitis and enthesitis. In this review, we focus on the psoriatic joint and discuss pathways that underlie synovial, cartilage and bone inflammation and highlight key histopathologic features. The pivotal inflammatory mechanisms and pathobiology of PsA parallel findings in other forms of spondyloarthritis but are distinct from disease pathways described in rheumatoid synovitis and bone disease. The diagnosis of PsA from both a clinical and imaging perspective is also discussed.

2016-01-01

This paper details the development and early testing of a compliant suspension for a microspine gripper device for asteroid capture or micro-gravity percussive drilling. The microspine gripper architecture is reviewed, and a proposed microspine suspension design is presented and discussed. Prototyping methods are discussed, as well as testing methods and results. A path forward is identified from the results of the testing completed thus far. Key findings include: the microspine concept has been established as a valid architecture and the compliant suspension exhibits the desired stiffness characteristics for good gripping behavior. These developments will aid in developing the capability to grasp irregularly shaped boulders in micro-gravity.

2004-01-01

In this minireview, we discuss different strategies to dissect genetically the keystones of learning and memory. First, we broadly sketch the neurogenetic analysis of complex traits in mice. We then discuss two general strategies to find genes affecting learning and memory: candidate gene studies and whole genome searches. Next, we briefly review more recently developed techniques, such as microarrays and RNA interference. In addition, we focus on gene-environment interactions and endophenotypes. All sections are illustrated with examples from the learning and memory field, including a table summarizing the latest information about genes that have been shown to have effects on learning and memory.

Equatorial bottomside sinusoidal (BSS) irregularities have been studied by applying techniques of cross-correlation and spectral analysis to the Atmosphere Explorer data set. The phase of the cross-correlations of the plasma number density is discussed and the two drift velocity components observed using the retarding potential analyzer and ion drift meter on the satellite are discussed. Morphology is addressed, presenting the geographical distributions of the occurrence of BSS events for the equinoxes and solstices. Physical processes including the ion Larmor flux, interhemispheric plasma flows, and variations in the lower F region Pedersen conductivity are invoked to explain the findings.

Carter, Chris T

2015-01-01

This article describes and discusses the case of an adult female with cholecystitis characterized on initial presentation as acute thoracolumbar pain. A 34-year-old female presented for care with a complaint of acute right sided lower thoracic and upper lumbar pain with associated significant hyperalgesia and muscular hypertonicity. The patient was examined, referred, and later diagnosed by use of ultrasound imaging. Despite many initial physical examination findings of musculoskeletal dysfunction, this case demonstrates the significance of visceral referred pain, viscerosomatic hyperalgesia & hypertonicity, and how these neurological processes can mimic mechanical pain syndromes. A clinical neurological discussion of cholecystitis visceral pain and referred viscerosomatic phenomena is included.

Purpose of Review This review discusses management of status epilepticus in children including both anticonvulsant medications and overall management approaches. Recent Findings Rapid management of status epilepticus is associated with a greater likelihood of seizure termination and better outcomes, yet data indicate there are often management delays. This review discusses an overall management approach aiming to simultaneously identify and manage underlying precipitant etiologies, administer anticonvulsants in rapid succession until seizures have terminated, and identify and manage systemic complications. An example management pathway is provided. Summary Status epilepticus is a common neurologic emergency in children and requires rapid intervention. Having a predetermined status epilepticus management pathway can expedite management. PMID:25304961

2018-05-01

Functional abdominal pain disorders, including irritable bowel syndrome, are common in children and treatment can often be difficult. Pharmacological therapies and complementary treatments are widely used, despite the limited data in pediatrics. Areas covered: This review provides an overview of the available data for the use of diet, probiotics, percutaneous electrical nerve stimulation, and psychosocial interventions, including hypnotherapy, yoga, cognitive and behavioral therapy, and mind-body interventions for the treatment of functional abdominal pain disorders in children. The literature review included a PubMed search by each therapy, children, abdominal pain, and irritable bowel syndrome. Relevant articles to this review are discussed. Expert commentary: The decision on the use of pharmacological and complementary therapies should be based on clinical findings, evidence, availability, and in-depth discussion with the patient and family. The physician should provide education on the different interventions and their role on the treatment in an empathetic and warm manner providing ample time for the family to ask questions.

How teachers can help learners build storage and retrieval strength.

Desy, Janeve; Busche, Kevin; Cusano, Ronald; Veale, Pamela; Coderre, Sylvain; McLaughlin, Kevin

2018-04-01

To be an effective teacher, content expertise is necessary but alone does not guarantee optimal learning outcomes for students. In this article, the authors discuss ways in which medical teachers can shape the learning of their students and enable them to become more efficient and effective learners. Using Bjork and Bjork's new theory of disuse as their framework, the authors discuss strategies to improve storage strength of to-be-learned information and strategies to improve retrieval strength of learned information. Strategies to improve storage strength include optimizing cognitive load, providing causal explanations, and giving effective feedback. Strategies to improve retrieval strength include situated cognition and various types of retrieval practice. Adopting these teaching strategies should hopefully help teachers improve the learning outcomes of their students, but there is still a need for further research into the science of learning and the science of instruction, including comparative effectiveness of different teaching strategies and how best to translate findings from the psychology literature into medical education.

Barriers and facilitators of HIV prevention with heterosexual Latino couples: beliefs of four stakeholder groups.

PubMed

Pérez-Jiménez, David; Seal, David W; Serrano-García, Irma

2009-01-01

Although HIV prevention interventions for women are efficacious, long-term behavior change maintenance within power-imbalanced heterosexual relationships has been difficult. To explore the feasibility, content, and format of an HIV intervention for Latino couples, the authors conducted 13 focus groups with HIV/AIDS researchers, service providers, and heterosexual men and women in Puerto Rico, the Dominican Republic, and Mexico. Reasons that participants thought that men should be involved in prevention efforts included promotion of shared responsibility, creation of a safe environment for open conversation about sex, and increased sexual negotiation skills. Perceived barriers to men's involvement included cultural taboos, sexual conservatism associated with Catholicism and machismo, and power-imbalanced relationships. Participants stressed the need for recruitment of men within naturally occurring settings or by influential community leaders. Participants indicated that couples-level interventions would be successful if they used strong coed facilitators, included both unigender and mixed-gender discussion opportunities, and addressed personally meaningful topics. Implications of these findings are discussed.

Data accessibility and transfer of information, including the land resources information system pilot, are structured as large computer information networks. These pilot efforts include the reduction of the difficulty to find and use data, reducing processing costs, and minimize incompatibility between data sources. Artificial Intelligence (AI) techniques were suggested to achieve these goals. The applicability of certain AI techniques are explored in the context of distributed problem solving systems and the pilot land data system (PLDS). The topics discussed include: PLDS and its data processing requirements, expert systems and PLDS, distributed problem solving systems, AI problem solving paradigms, query processing, and distributed data bases.

New horizons in fall prevention.

Lord, Stephen R; Close, Jacqueline C T

2018-04-25

Falls pose a major threat to the well-being and quality of life of older people. Falls can result in fractures and other injuries, disability and fear and can trigger a decline in physical function and loss of autonomy. This article synthesises recent published findings on fall risk and mobility assessments and fall prevention interventions and considers how this field of research may evolve in the future. Fall risk topics include the utility of remote monitoring using wearable sensors and recent work investigating brain activation and gait adaptability. New approaches for exercise for fall prevention including dual-task training, cognitive-motor training with exergames and reactive step training are discussed. Additional fall prevention strategies considered include the prevention of falls in older people with dementia and Parkinson's disease, drugs for fall prevention and safe flooring for preventing fall-related injuries. The review discusses how these new initiatives and technologies have potential for effective fall prevention and improved quality of life. It concludes by emphasising the need for a continued focus on translation of evidence into practice including robust effectiveness evaluations of so that resources can be appropriately targeted into the future.

Measuring mumbo jumbo: A preliminary quantification of the use of jargon in science communication.

PubMed

Sharon, Aviv J; Baram-Tsabari, Ayelet

2014-07-01

Leaders of the scientific community encourage scientists to learn effective science communication, including honing the skill to discuss science with little professional jargon. However, avoiding jargon is not trivial for scientists for several reasons, and this demands special attention in teaching and evaluation. Despite this, no standard measurement for the use of scientific jargon in speech has been developed to date. Here a standard yardstick for the use of scientific jargon in spoken texts, using a computational linguistics approach, is proposed. Analyzed transcripts included academic speech, scientific TEDTalks, and communication about the discovery of a Higgs-like boson at CERN. Findings suggest that scientists use less jargon in communication with a general audience than in communication with peers, but not always less obscure jargon. These findings may lay the groundwork for evaluating the use of jargon.

Functional abdominal pain in childhood: background studies and recent research trends.

PubMed

Levy, Rona L; van Tilburg, Miranda A L

2012-01-01

The present review summarizes many of the major research trends investigated in the past five years regarding pediatric functional abdominal pain, and also summarizes the primary related findings from the authors' research program. Specific areas discussed based on work within the authors' group include familial illness patterns, genetics, traits, and mechanisms or processes related to abdominal pain. Topics covered from research published in the past five years include prevalence and cost, longitudinal follow-up, overlap with other disorders, etiology and mechanisms behind functional abdominal pain and treatment studies. It is hoped that findings from this work in abdominal pain will be interpreted as a framework for understanding the processes by which other pain phenomena and, more broadly, reactions to any physical state, can be developed and maintained in children. The present article concludes with recommendations for clinical practice and research.

An exploration of clinical decision making in mental health triage.

PubMed

Sands, Natisha

2009-08-01

Mental health (MH) triage is a specialist area of clinical nursing practice that involves complex decision making. The discussion in this article draws on the findings of a Ph.D. study that involved a statewide investigation of the scope of MH triage nursing practice in Victoria, Australia. Although the original Ph.D. study investigated a number of core practices in MH triage, the focus of the discussion in this article is specifically on the findings related to clinical decision making in MH triage, which have not previously been published. The study employed an exploratory descriptive research design that used mixed data collection methods including a survey questionnaire (n = 139) and semistructured interviews (n = 21). The study findings related to decision making revealed a lack of empirically tested evidence-based decision-making frameworks currently in use to support MH triage nursing practice. MH triage clinicians in Australia rely heavily on clinical experience to underpin decision making and have little of knowledge of theoretical models for practice, such as methodologies for rating urgency. A key recommendation arising from the study is the need to develop evidence-based decision-making frameworks such as clinical guidelines to inform and support MH triage clinical decision making.

Being part of an unfolding story: togetherness in everyday occupations when ageing.

Nyman, Anneli; Josephsson, Staffan; Isaksson, Gunilla

2014-09-01

The aim of this study was to explore and enhance the understanding of how togetherness in everyday occupations is experienced and discussed among older adults. Focus-group discussions generated the data and a total of 12 participants, including six women and six men, divided into three groups, participated in this study. Analysis was performed using a grounded theory approach. The findings reflect how togetherness in everyday occupations can be comprehended as multifold transactional processes, emphasizing how an acted belonging was a situated experience connecting people and places through unfolding stories. The findings suggest that the process of meaning-making in ongoing life was closely associated with togetherness and was negotiated with others through shared culture and experiences. Togetherness meant being part of something in which the persons involved were contributing to each other in various ways. However, being part of togetherness was complicated, especially when the person's life situation was challenged in some way. It was apparent from the analysis that togetherness could not be taken for granted. Rather, the findings reflect how togetherness was created and maintained through an ongoing process of nurturing established relationships as well as creating something new around occupations with others.

Reflections on empathy in medical education: What can we learn from social neurosciences?

PubMed

Preusche, Ingrid; Lamm, Claus

2016-03-01

The role of empathy in human social interaction has been examined in several research fields, including medical education (ME) and social neuroscience (SN). SN yields insights into empathy based on neurobiological processes, and such information may also be relevant to ME. In this reflection article, the authors first critically review current definitions and concepts of empathy in ME and link them to recent SN findings. In the light of recent evidence from SN, research in ME regarding the positive and negative effects of empathy for physicians and patients is discussed, as well as the question whether (future) physicians differ from the general population with regard to empathic skills. Commonly used SN paradigms and ME approaches to assess empathy are contrasted, a joint approach is advocated, and implications for further interdisciplinary studies are outlined. Finally, the authors delineate the contribution of SN to the question of whether empathy is teachable, and argue that SN findings represent a potential for new ME training approaches. In conclusion, the authors discuss how the incorporation of perspectives on empathy from different research areas would benefit ME, and suggest the translation and integration of such findings into ME research approaches.

The Weak Spots in Contemporary Science (and How to Fix Them).

PubMed

Wicherts, Jelte M

2017-11-27

In this review, the author discusses several of the weak spots in contemporary science, including scientific misconduct, the problems of post hoc hypothesizing (HARKing), outcome switching, theoretical bloopers in formulating research questions and hypotheses, selective reading of the literature, selective citing of previous results, improper blinding and other design failures, p-hacking or researchers' tendency to analyze data in many different ways to find positive (typically significant) results, errors and biases in the reporting of results, and publication bias. The author presents some empirical results highlighting problems that lower the trustworthiness of reported results in scientific literatures, including that of animal welfare studies. Some of the underlying causes of these biases are discussed based on the notion that researchers are only human and hence are not immune to confirmation bias, hindsight bias, and minor ethical transgressions. The author discusses solutions in the form of enhanced transparency, sharing of data and materials, (post-publication) peer review, pre-registration, registered reports, improved training, reporting guidelines, replication, dealing with publication bias, alternative inferential techniques, power, and other statistical tools.

Complex Decision-Making in Heart Failure: A Systematic Review and Thematic Analysis.

PubMed

Hamel, Aimee V; Gaugler, Joseph E; Porta, Carolyn M; Hadidi, Niloufar Niakosari

Heart failure follows a highly variable and difficult course. Patients face complex decisions, including treatment with implantable cardiac defibrillators, mechanical circulatory support, and heart transplantation. The course of decision-making across multiple treatments is unclear yet integral to providing informed and shared decision-making. Recognizing commonalities across treatment decisions could help nurses and physicians to identify opportunities to introduce discussions and support shared decision-making. The specific aims of this review are to examine complex treatment decision-making, specifically implantable cardiac defibrillators, ventricular assist device, and cardiac transplantation, and to recognize commonalities and key points in the decisional process. MEDLINE, CINAHL, PsycINFO, and Web of Science were searched for English-language studies that included qualitative findings reflecting the complexity of heart failure decision-making. Using a 3-step process, findings were synthesized into themes and subthemes. Twelve articles met criteria for inclusion. Participants included patients, caregivers, and clinicians and included decisions to undergo and decline treatment. Emergent themes were "processing the decision," "timing and prognostication," and "considering the future." Subthemes described how participants received and understood information about the therapy, making and changing a treatment decision, timing their decision and gauging health status outcomes in the context of their decision, the influence of a life or death decision, and the future as a factor in their decisional process. Commonalities were present across therapies, which involved the timing of discussions, the delivery of information, and considerations of the future. Exploring this further could help support patient-centered care and optimize shared decision-making interventions.

We discuss the possible factorization of the tensor asymmetrymore » $$A^T_d$$ measured for polarized deuteron targets within a relativistic framework. We define a reduced asymmetry and find that factorization holds only in plane wave impulse approximation and if $p$-waves are neglected. Our numerical results show a strong factorization breaking once final state interactions are included. We also compare the $d$-wave content of the wave functions with the size of the factored, reduced asymmetry and find that there is no systematic relationship of this quantity to the d-wave probability of the various wave functions.« less

2010-03-17

The National Institutes of Health (NIH) supports research about and the development of better therapies for treating exposure to toxic chemicals that could be used in a terrorist attack or released during an industrial accident. A review of recent research published by NIH investigators working in this field indicates that scientific advances in this area also have implications for reducing the burden of other neurological diseases and disorders. Some key examples discussed include studies on the development of therapeutic drugs to treat seizures and the neuropathology caused by chemical nerve agents, which may help find better cures for epilepsy, stroke, and neurodegenerative diseases.

The wage effects of obesity: a longitudinal study.

PubMed

Baum, Charles L; Ford, William F

2004-09-01

We use National Longitudinal Survey of Youth (NLSY) data to examine the effects of obesity on wages by gender. Sample means indicate that both men and women experience a persistent obesity wage penalty over the first two decades of their careers. We then control for a standard set of socioeconomic and familial variables but find that standard covariates do not explain why obese workers experience persistent wage penalties. This suggests that other variables -- including job discrimination, health-related factors and/or obese workers' behavior patterns -- may be the channels through which obesity adversely affects wages. The study closes with a discussion of the public policy implications suggested by these findings.

Investigation of enablers of knowledge transfer in the medical industry.

2008-01-01

This paper presents a research model for investigating the relationship between organisational enablers and the Knowledge Transfer (KT) Performance (KTP) in the medical industry. The enablers include leadership, organisational culture, Information Technology (IT) and individual performance measurement, and KTP is determined by individual capability, organisational capability and product/service innovation. This paper chose professional medical personnel as the research subject to determine whether or not these enablers affect KT. The findings show that only leadership directly affects the KTP, with IT also impacting both organisational capability and product/service innovation. The implications of these findings are discussed based on interviews with experts and practitioners.

Image manipulation as research misconduct.

2009-06-01

A growing number of research misconduct cases handled by the Office of Research Integrity involve image manipulations. Manipulations may include simple image enhancements, misrepresenting an image as something different from what it is, and altering specific features of an image. Through a study of specific cases, the misconduct findings associated with image manipulation, detection methods and those likely to identify such manipulations, are discussed. This article explores sanctions imposed against guilty researchers and the factors that resulted in no misconduct finding although relevant images clearly were flawed. Although new detection tools are available for universities and journals to detect questionable images, this article explores why these tools have not been embraced.

The early stages of antibiotic development include the identification of novel hit compounds. Since actinomycetes and myxobacteria are still the most important natural sources of active metabolites, we provide an overview on these producers and discuss three of the most promising approaches toward finding novel anti-infectives from microorganisms. These are defined as the use of biodiversity to find novel producers, the variation of culture conditions and induction of silent genes, and the exploitation of the genomic potential of producers via "genome mining". Challenges that exist beyond compound discovery are outlined in the last section. Copyright © 2013 Elsevier GmbH. All rights reserved.

This study investigated the relationship between wellbeing and marital quality in a married lesbian sample from Massachusetts. Two hundred twenty five (225) participants responded to this mailed survey study. Participants completed a demographic questionnaire, the Dyadic Adjustment Scale (DAS), and the World Health Organization Quality of Life-Brief Instrument (WHOQOL-Bref). DAS scores were a strong predictor of reported wellbeing in all quality of life domains including physical, psychological, and financial wellbeing. Results support the finding in the heterosexual marriage literature that healthy marriage is associated with distinct wellbeing benefits for lesbian couples. Implications of these findings are discussed.

Finding golden mean in a physics exercise

NASA Astrophysics Data System (ADS)

Benedetto, Elmo

2017-07-01

The golden mean is an algebraic irrational number that has captured the popular imagination and is discussed in many books. Indeed, some scientists believe that it appears in some patterns in nature, including the spiral arrangement of leaves and other plant parts. Generally, the golden mean is introduced in geometry and the textbooks give the definition showing a graphical method to determine it. In this short note, we want to find this number by studying projectile motion. This could be a way to introduce the golden mean (also said to be the golden ratio, golden section, Fidia constant, divine proportion or extreme and mean ratio) in a physics course.

Neurocognitive mechanisms of the flow state.

PubMed

Harris, David J; Vine, Samuel J; Wilson, Mark R

2017-01-01

While the experience of flow is often described in attentional terms-focused concentration or task absorption-specific cognitive mechanisms have received limited interest. We propose that an attentional explanation provides the best way to advance theoretical models and produce practical applications, as well as providing potential solutions to core issues such as how an objectively difficult task can be subjectively effortless. Recent research has begun to utilize brain-imaging techniques to investigate neurocognitive changes during flow, which enables attentional mechanisms to be understood in greater detail. Some tensions within flow research are discussed; including the dissociation between psychophysiological and experiential measures, and the equivocal neuroimaging findings supporting prominent accounts of hypofrontality. While flow has received only preliminary investigation from a neuroscientific perspective, findings already provide important insights into the crucial role played by higher-order attentional networks, and clear indications of reduced activity in brain regions linked to self-referential processing. The manner in which these processes may benefit sporting performance are discussed. © 2017 Elsevier B.V. All rights reserved.

Researching Pacific island livelihoods: mobility, natural resource management and nissology.

PubMed

Christensen, Andreas E; Mertz, Ole

2010-01-01

Small island literature is vast in focus and aim, and is rooted in many different disciplines. The challenge is to find common grounds for researching small islands conceptually and theoretically. The aim of this article is to comment on how to research small islands, including a discussion on contemporary theories of nissology and conceptual analytical frameworks for island research. Through a review of selected case-study-based island literature on changing livelihoods coming out of the South Pacific, we wish to illustrate and discuss advantages of finding common grounds for small island studies. The focus is on two dimensions of island livelihood, migration and natural resource management, both of which are significant contributors in making island livelihoods and shaping Pacific seascapes. We argue that there is still a substantial lack of studies targeting small island dynamics that are empirical and interdisciplinary in focus and link socio-economic and ecological processes of small island societies at temporal and analytical scales.

Characteristics of Qualitative Descriptive Studies: A Systematic Review

PubMed Central

Kim, Hyejin; Sefcik, Justine S.; Bradway, Christine

2016-01-01

Qualitative description (QD) is a term that is widely used to describe qualitative studies of health care and nursing-related phenomena. However, limited discussions regarding QD are found in the existing literature. In this systematic review, we identified characteristics of methods and findings reported in research articles published in 2014 whose authors identified the work as QD. After searching and screening, data were extracted from the sample of 55 QD articles and examined to characterize research objectives, design justification, theoretical/philosophical frameworks, sampling and sample size, data collection and sources, data analysis, and presentation of findings. In this review, three primary findings were identified. First, despite inconsistencies, most articles included characteristics consistent with limited, available QD definitions and descriptions. Next, flexibility or variability of methods was common and desirable for obtaining rich data and achieving understanding of a phenomenon. Finally, justification for how a QD approach was chosen and why it would be an appropriate fit for a particular study was limited in the sample and, therefore, in need of increased attention. Based on these findings, recommendations include encouragement to researchers to provide as many details as possible regarding the methods of their QD study so that readers can determine whether the methods used were reasonable and effective in producing useful findings.

There is growing interest in simplifying recommendations to vaccinate Americans against influenza. The article discusses interviews with 35 stakeholders from the medical, public health, educational, insurance, and vaccine industry sectors to assess the potential for policy change, and discusses questions posed to the interviewees on current and future influenza vaccination policy and barriers to policy change. About 97% of respondents support the expansion of vaccination for all school-age children, and about 95% support universal vaccination, but there are reservations expressed by the respondents, despite the support for this policy change. Barriers to influenza vaccination recommendations include access, supply, confusing recommendations, and public perceptions. Barriers to universal vaccination include lack of infrastructure, cost, need for education, and vaccine supply. Issues concerning resources and education are challenges that impede policy change. The study findings can be useful to policy makers and practitioners for reviewing U.S. vaccination policy and changes to the policy.

Screening for trace explosives by AccuTOF™-DART®: an in-depth validation study.

PubMed

Sisco, Edward; Dake, Jeffrey; Bridge, Candice

2013-10-10

Ambient ionization mass spectrometry is finding increasing utility as a rapid analysis technique in a number of fields. In forensic science specifically, analysis of many types of samples, including drugs, explosives, inks, bank dye, and lotions, has been shown to be possible using these techniques [1]. This paper focuses on one type of ambient ionization mass spectrometry, Direct Analysis in Real Time Mass Spectrometry (DART-MS or DART), and its viability as a screening tool for trace explosives analysis. In order to assess viability, a validation study was completed which focused on the analysis of trace amounts of nitro and peroxide based explosives. Topics which were studied, and are discussed, include method optimization, reproducibility, sensitivity, development of a search library, discrimination of mixtures, and blind sampling. Advantages and disadvantages of this technique over other similar screening techniques are also discussed. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

2012-04-01

Cultural competence is increasingly recognized as an essential component of effective mental health care delivery to address diversity and equity issues. Drawing from the literature and our experience in providing cultural competence consultation and training, the paper will discuss our perspective on the foundational concepts of cultural competence and how it applies to a health care organization, including its programs and services. Based on a recent consultation project, we present a methodology for assessing cultural competence in health care organizations, involving mixed quantitative and qualitative methods. Key findings and recommendations from the resulting cultural competence plan are discussed, including core principles, change strategies, and an Organizational Cultural Competence Framework, which may be applicable to other health care institutions seeking such changes. This framework, consisting of eight domains, can be used for organizational assessment and cultural competence planning, ultimately aiming at enhancing mental health care service to the diverse patients, families, and communities.

Biomarkers for Parkinson's disease (PD) diagnosis, prognostication and clinical trial cohort selection are an urgent need. While many promising markers have been discovered through the National Institute of Neurological Disorders and Stroke Parkinson's Disease Biomarker Program (PDBP) and other mechanisms, no single PD marker or set of markers are ready for clinical use. Here we discuss the current state of biomarker discovery for platforms relevant to PDBP. We discuss the role of the PDBP in PD biomarker identification and present guidelines to facilitate their development. These guidelines include: harmonizing procedures for biofluid acquisition and clinical assessments, replication of the most promising biomarkers, support and encouragement of publications that report negative findings, longitudinal follow-up of current cohorts including the PDBP, testing of wearable technologies to capture readouts between study visits and development of recently diagnosed (de novo) cohorts to foster identification of the earliest markers of disease onset.

The progress for the first year of the work done under the Director's Discretionary Fund (DDF) research project entitled, 'Development of Si(1-x)Ge(x) Technology for Microwave Sensing Applications.' This project includes basic material characterization studies of silicon-germanium (SiGe), device processing on both silicon (Si) and SiGe substrates, and microwave characterization of transmission lines on silicon substrates. The material characterization studies consisted of ellipsometric and magneto-transport measurements and theoretical calculations of the SiGe band-structure. The device fabrication efforts consisted of establishing SiGe device processing capabilities in the Lewis cleanroom. The characterization of microwave transmission lines included studying the losses of various coplanar transmission lines and the development of transitions on silicon. Each part of the project is discussed individually and the findings for each part are presented. Future directions are also discussed.

Identifying Mother-Child Interaction Styles Using a Person-Centered Approach.

2014-05-01

Parent-child conflict in the context of a supportive relationship has been discussed as a potentially constructive interaction pattern; the current study is the first to test this using a holistic analytic approach. Interaction styles, defined as mother-child conflict in the context of maternal sensitivity, were identified and described with demographic and stress-related characteristics of families. Longitudinal associations were tested between interaction styles and children's later social competence. Participants included 814 partnered mothers with a first-grade child. Latent profile analysis identified agreeable , dynamic , and disconnected interaction styles. Mothers' intimacy with a partner, depressive symptoms, and authoritarian childrearing beliefs, along with children's later conflict with a best friend and externalizing problems, were associated with group membership. Notably, the dynamic style, characterized by high sensitivity and high conflict, included families who experienced psychological and relational stressors. Findings are discussed with regard to how family stressors shape parent-child interaction patterns.

We profile and optimize calculations performed with the BerkeleyGW code on the Xeon-Phi architecture. BerkeleyGW depends both on hand-tuned critical kernels as well as on BLAS and FFT libraries. We describe the optimization process and performance improvements achieved. We discuss a layered parallelization strategy to take advantage of vector, thread and node-level parallelism. We discuss locality changes (including the consequence of the lack of L3 cache) and effective use of the on-package high-bandwidth memory. We show preliminary results on Knights-Landing including a roofline study of code performance before and after a number of optimizations. We find that the GW methodmore » is particularly well-suited for many-core architectures due to the ability to exploit a large amount of parallelism over plane-wave components, band-pairs, and frequencies.« less

Resumption of gainful employment in aphasics: preliminary findings.

Carriero, M R; Faglia, L; Vignolo, L A

1987-12-01

We report preliminary data on aphasic patients who, in spite of their language problems, have succeeded in finding a reasonably satisfactory occupational resettlement. Patients who: (a) still had a moderate to sever aphasia, (b) had resumed a gainful employment requiring interpersonal communication, were recalled for a check-up and assessed with: (1) a comprehensive aphasia test: (2) a semistructured interview including detailed questioning about the type and reaction to aphasia, the type of work before the onset of aphasia, the type of current work with particular emphasis on the patients' compensatory mechanisms and emotional reactions. Results comprise 10 cases up to date. One case is described in detail. Findings indicate that the ability to resume a gainful occupation is often greater than could be expected on the sole basis of formal language examination. Findings are discussed from a neuropsychological, social and rehabilitation point of view.

Visual distinctiveness can enhance recency effects.

Bornstein, B H; Neely, C B; LeCompte, D C

1995-05-01

Experimental efforts to meliorate the modality effect have included attempts to make the visual stimulus more distinctive. McDowd and Madigan (1991) failed to find an enhanced recency effect in serial recall when the last item was made more distinct in terms of its color. In an attempt to extend this finding, three experiments were conducted in which visual distinctiveness was manipulated in a different manner, by combining the dimensions of physical size and coloration (i.e., whether the stimuli were solid or outlined in relief). Contrary to previous findings, recency was enhanced when the size and coloration of the last item differed from the other items in the list, regardless of whether the "distinctive" item was larger or smaller than the remaining items. The findings are considered in light of other research that has failed to obtain a similar enhanced recency effect, and their implications for current theories of the modality effect are discussed.

Caregiving Youth Knowledge and Perceptions of Parental End-of-Life Wishes in Huntington's Disease.

2016-01-01

Knowledge of patient end-of-life (EOL) wishes and discussions are vital for family caregivers, including children and youth who may be in caregiving roles ("young carers" or "caregiving youth"). However, little is known about caregiving youth awareness and perceptions of EOL issues. This study sought to explore caregiving youth knowledge of EOL wishes and their willingness for EOL discussions. Face-to-face interviews with 40 caregiving youth ages 10-20, who have a parent with Huntington's disease (HD), provided information about their knowledge of the presence of their ill parent's living will (LW) and durable power of attorney for health care (DPAHC), and willingness to talk with the parent about EOL choices and possibility of death. Less than one-half of the participants were aware of the parent's LW or DPAHC. Content analysis revealed themes in reasons to want or not want EOL discussion with the parent: respect for the parent's wishes, caregiving youths' opinion not valued, and avoidance of EOL issues. Themes also included reasons to not want discussion with the parent about possibility of death: protecting the parent, parent in denial, parent not ready, and realization of the terminal outcome. Findings suggest HD patients and their caregiving youth need support for open EOL discussions, and could benefit from educational programs and support groups around EOL issues.

2016-12-01

In this Comment, we reexamine the security of phase-encoded quantum private query (QPQ). We find that the current phase-encoded QPQ protocols, including their applications, are vulnerable to a probabilistic entangle-and-measure attack performed by the owner of the database. Furthermore, we discuss how to overcome this security loophole and present an improved cheat-sensitive QPQ protocol without losing the good features of the original protocol.

Approximation Of Multi-Valued Inverse Functions Using Clustering And Sugeno Fuzzy Inference

NASA Technical Reports Server (NTRS)

Walden, Maria A.; Bikdash, Marwan; Homaifar, Abdollah

1998-01-01

Finding the inverse of a continuous function can be challenging and computationally expensive when the inverse function is multi-valued. Difficulties may be compounded when the function itself is difficult to evaluate. We show that we can use fuzzy-logic approximators such as Sugeno inference systems to compute the inverse on-line. To do so, a fuzzy clustering algorithm can be used in conjunction with a discriminating function to split the function data into branches for the different values of the forward function. These data sets are then fed into a recursive least-squares learning algorithm that finds the proper coefficients of the Sugeno approximators; each Sugeno approximator finds one value of the inverse function. Discussions about the accuracy of the approximation will be included.

This study utilizes data from the older African American sub-sample of the National Survey of American Life (n=837) to examine the sociodemographic and denominational correlates of organizational religious involvement among older African Americans. Six measures of organizational religious participation are utilized, including two measures of time allocation for organized religious pursuits. The findings indicate significant gender, region, marital status and denominational differences in organizational religiosity. Of particular note, although older black women generally displayed higher levels of religious participation, older black men spent more hours per week in other activities at their place of worship. The findings are discussed in relation to prior work in the area of religious involvement among older adults. New directions for research on religious time allocation are outlined.

Corporate coalitions and policy making in the European Union: how and why British American Tobacco promoted "Better Regulation".

Smith, Katherine Elizabeth; Fooks, Gary; Gilmore, Anna B; Collin, Jeff; Weishaar, Heide

2015-04-01

Over the past fifteen years, an interconnected set of regulatory reforms, known as Better Regulation, has been adopted across Europe, marking a significant shift in the way that European Union policies are developed. There has been little exploration of the origins of these reforms, which include mandatory ex ante impact assessment. Drawing on documentary and interview data, this article discusses how and why large corporations, notably British American Tobacco (BAT), worked to influence and promote these reforms. Our analysis highlights (1) how policy entrepreneurs with sufficient resources (such as large corporations) can shape the membership and direction of advocacy coalitions; (2) the extent to which "think tanks" may be prepared to lobby on behalf of commercial clients; and (3) why regulated industries (including tobacco) may favor the use of "evidence tools," such as impact assessments, in policy making. We argue that a key aspect of BAT's ability to shape regulatory reform involved the deliberate construction of a vaguely defined idea that could be strategically adapted to appeal to diverse constituencies. We discuss the theoretical implications of this finding for the Advocacy Coalition Framework, as well as the practical implications of the findings for efforts to promote transparency and public health in the European Union.

Early numeracy skills in preschool-aged children: a review of neurocognitive findings and implications for assessment and intervention.

Raghubar, Kimberly P; Barnes, Marcia A

2017-02-01

The goals are to (1) provide a review of the typical and atypical development of early numeracy; (2) present what is known about the neurocognitive underpinnings of early numeracy; and (3) discuss the implications for early assessment and intervention. Studies on the development of typical and atypical early numeracy are reviewed with a particular focus on longitudinal findings including those from our work on spina bifida myelomeningocele. Implications of this research for assessment are presented. The paper ends with a discussion of early math interventions. Learning to count, identify numbers, and compare and manipulate quantities are key early numeracy skills. These are powerful predictors of school-age mathematical learning and performance. General neurocognitive abilities such as working memory and language, are also important for the development of early numeracy. It is recommended that early assessment for risk of mathematical learning difficulties include tests of both early number knowledge and key neurocognitive abilities. Math-specific interventions are most effective for improving early numeracy. There is currently little evidence that training of general cognitive functions transfers to mathematical learning. Understanding the development of early numeracy skills and their neurocognitive predictors offer important insights into early assessment and intervention for children at risk for or with mathematical learning difficulties.

2017-01-01

Novel pharmacotherapies that improve outcomes for individuals with stress-related psychiatric disorders are needed. The neurohormone oxytocin (OT) is a promising candidate given its influence on the social–emotional brain. In this review, we present an overview of evidence supporting OT’s utility for treating major depressive disorder and posttraumatic stress disorder. We first discuss endogenous OT, which research suggests is not yet a reliable biomarker of stress-related disorders. Second, we review effects of intranasal (IN) OT on processes relevant to stress-related disorders in healthy populations (anhedonia, reward processing, psychosocial stress reactivity, fear/anxiety, and social behavior) and their neurobiological mechanisms (e.g., the salience network and hypothalamic–pituitary–adrenal axis). Third, we present the sparse but promising findings from clinical populations, followed by discussion of critical moderating variables to consider in the service of maximizing the therapeutic potential of OT (e.g., patient sex and child maltreatment). We also identify heterogeneous findings and limitations of existing research, including reliance on single-dose studies in psychiatrically healthy samples and unanswered questions regarding the effectiveness of IN drug delivery and dosing schedules. Well-controlled multidose studies including women and measures of potentially moderating variables are sorely needed and would inform our understanding of the utility of OT for preventing and treating stress-related psychiatric disorders.

This paper reviews and then discusses selected findings from a seventeen year study about the population prevalence of people who inject drugs (PWID) and of HIV prevalence and mortality among PWID in 96 large US metropolitan areas. Unlike most research, this study was conducted with the metropolitan area as the level of analysis. It found that metropolitan area measures of income inequality and of structural racism predicted all of these outcomes, and that rates of arrest for heroin and/or cocaine predicted HIV prevalence and mortality but did not predict changes in PWID population prevalence. Income inequality and measures of structural racism were associated with hard drug arrests or other properties of policing. These findings, whose limitations and implications for further research are discussed, suggest that efforts to respond to HIV and to drug injection should include supra-individual efforts to reduce both income inequality and racism. At a time when major social movements in many countries are trying to reduce inequality, racism and oppression (including reforming drug laws), these macro-social issues in public health should be both addressable and a priority in both research and action.

A trait based approach to defining valued mentoring qualities

NASA Astrophysics Data System (ADS)

Pendall, E.

2012-12-01

Graduate training in the sciences requires strong personal interactions among faculty, senior lab members and more junior members. Within the lab-group setting we learn to frame problems, to conduct research and to communicate findings. The result is that individual scientists are partly shaped by a few influential mentors. We have all been influenced by special relationships with mentors, and on reflection we may find that certain qualities have been especially influential in our career choices. In this presentation I will discuss favorable mentoring traits as determined from an informal survey of scientists in varying stages of careers and from diverse backgrounds. Respondents addressed questions about traits they value in their mentors in several categories: 1) personal qualities such as approachability, humor and encouragement; background including gender, ethnicity, and family status; 2) scientific qualities including discipline or specialization, perceived stature in discipline, seniority, breadth of perspective, and level of expectations; and 3) community-oriented qualities promoted by mentors, such as encouraging service contributions and peer-mentoring within the lab group. The results will be compared among respondents by gender, ethnicity, stage of career, type of work, and subdiscipline within the broadly defined Biogeoscience community. We hope to contribute to the growing discussion on building a diverse and balanced scientific workforce.

African-American men have the highest prostate cancer rates worldwide, and innovative efforts are needed to increase cancer prevention and screening behaviors among this population. Formative research was conducted to assess attitudes and behaviors linked to prostate cancer prevention activities that could be used to develop a culturally relevant intervention for an African-American church-based population. Four gender-specific focus groups were conducted with 29 men and women at two African-American churches in central North Carolina. Three primary themes emerged from the focus group discussions: culturally and gender-influenced beliefs and barriers about cancer prevention and screening; barriers related to the healthcare system: and religious influences, including the importance of spiritual beliefs and church support. These discussions revealed the importance of the black family, the positive influence of spouses/partners on promoting cancer screening and healthy behaviors, the roles of faith and church leadership, and beliefs about God's will for good health. These findings also revealed that there are still major barriers and challenges to cancer prevention among African Americans, including continued mistrust of the medical community and negative attitudes toward specific screening tests. Findings provide important insights to consider in implementing successful prostate cancer prevention interventions designed for church-based audiences.

Recent Insights Into Molecular Mechanisms of Propofol-Induced Developmental Neurotoxicity: Implications for the Protective Strategies.

PubMed

Bosnjak, Zeljko J; Logan, Sarah; Liu, Yanan; Bai, Xiaowen

2016-11-01

Mounting evidence has demonstrated that general anesthetics could induce developmental neurotoxicity, including acute widespread neuronal cell death, followed by long-term memory and learning abnormalities. Propofol is a commonly used intravenous anesthetic agent for the induction and maintenance of anesthesia and procedural and critical care sedation in children. Compared with other anesthetic drugs, little information is available on its potential contributions to neurotoxicity. Growing evidence from multiple experimental models showed a similar neurotoxic effect of propofol as observed in other anesthetic drugs, raising serious concerns regarding pediatric propofol anesthesia. The aim of this review is to summarize the current findings of propofol-induced developmental neurotoxicity. We first present the evidence of neurotoxicity from animal models, animal cell culture, and human stem cell-derived neuron culture studies. We then discuss the mechanism of propofol-induced developmental neurotoxicity, such as increased cell death in neurons and oligodendrocytes, dysregulation of neurogenesis, abnormal dendritic development, and decreases in neurotrophic factor expression. Recent findings of complex mechanisms of propofol action, including alterations in microRNAs and mitochondrial fission, are discussed as well. An understanding of the toxic effect of propofol and the underlying mechanisms may help to develop effective novel protective or therapeutic strategies for avoiding the neurotoxicity in the developing human brain.

To date, there have been efforts toward creating better health information access for Deaf American Sign Language (ASL) users. However, the usability of websites with access to health information in ASL has not been evaluated. Our article focuses on the usability of four health websites that include ASL videos. We seek to obtain ASL users' perspectives on the navigation of these ASL-accessible websites, finding the health information that they needed, and perceived ease of understanding ASL video content. ASL users (n = 32) were instructed to find specific information on four ASL-accessible websites, and answered questions related to (a) navigation to find the task, (b) website usability, and (c) ease of understanding ASL video content for each of the four websites. Participants also gave feedback on what they would like to see in an ASL health library website, including the benefit of added captioning and/or signer model to medical illustration of health videos. Participants who had lower health literacy had greater difficulty in finding information on ASL-accessible health websites. This article also describes the participants' preferences for an ideal ASL-accessible health website, and concludes with a discussion on the role of accessible websites in promoting health literacy in ASL users.

Detecting outliers and learning complex structures with large spectroscopic surveys - a case study with APOGEE stars

NASA Astrophysics Data System (ADS)

Reis, Itamar; Poznanski, Dovi; Baron, Dalya; Zasowski, Gail; Shahaf, Sahar

2018-05-01

In this work, we apply and expand on a recently introduced outlier detection algorithm that is based on an unsupervised random forest. We use the algorithm to calculate a similarity measure for stellar spectra from the Apache Point Observatory Galactic Evolution Experiment (APOGEE). We show that the similarity measure traces non-trivial physical properties and contains information about complex structures in the data. We use it for visualization and clustering of the data set, and discuss its ability to find groups of highly similar objects, including spectroscopic twins. Using the similarity matrix to search the data set for objects allows us to find objects that are impossible to find using their best-fitting model parameters. This includes extreme objects for which the models fail, and rare objects that are outside the scope of the model. We use the similarity measure to detect outliers in the data set, and find a number of previously unknown Be-type stars, spectroscopic binaries, carbon rich stars, young stars, and a few that we cannot interpret. Our work further demonstrates the potential for scientific discovery when combining machine learning methods with modern survey data.

2012-01-01

Obsessive-compulsive disorder (OCD) is a leading cause of disability worldwide, however, there is a lack of research that includes African Americans, thus it is unclear whether findings about symptom dimensions can be generalized to this population. A sample of adult African Americans with OCD (N=74) was recruited at the University of Pennsylvania (Penn) and administered the Yale Brown Obsessive-Compulsive checklist (YBOCS) to better understand the phenomenology of OCD in African Americans. Frequencies of symptoms are reported and compared to findings from the National Survey of American Life (NSAL; N=54). A principal components analysis of YBOCS categories and items was performed on the Penn sample. A six-component solution was found, that included Contamination & Washing, Hoarding, Sexual Obsessions & Reassurance, Aggression & Mental Compulsions, Symmetry & Perfectionism, and Doubt & Checking, explaining 59.1% of the variance. Factors identified were similar to those of previous studies in primarily white samples. African Americans with OCD reported more contamination symptoms and were twice as likely to report excessive concerns with animals as European Americans with OCD. The results indicate the presence of cultural differences, which is consistent with findings among non-clinical samples. Implications of these findings are discussed. PMID:22708117

Advance care planning and goals of care discussions involve the exploration of what is most important to a person, including their values and beliefs in preparation for health-care decision-making. Advance care planning conversations focus on planning for future health care, ensuring that an incapable person's wishes are known and can guide the person's substitute decision maker for future decision-making. Goals of care discussions focus on preparing for current decision-making by ensuring the person's goals guide this process. To provide evidence regarding tools and/or practices available for use by health-care providers to effectively facilitate advance care planning conversations and/or goals of care discussions. A systematic review was conducted focusing on guidelines, randomized trials, comparative studies, and noncomparative studies. Databases searched included MEDLINE, EMBASE, and the proceedings of the International Advance Care Planning Conference and the American Society of Clinical Oncology Palliative Care Symposium. Although several studies report positive findings, there is a lack of consistent patient outcome evidence to support any one clinical tool for use in advance care planning or goals of care discussions. Effective advance care planning conversations at both the population and the individual level require provider education and communication skill development, standardized and accessible documentation, quality improvement initiatives, and system-wide coordination to impact the population level. There is a need for research focused on goals of care discussions, to clarify the purpose and expected outcomes of these discussions, and to clearly differentiate goals of care from advance care planning.

A fundamental feature of community-based participatory research (CBPR) is sharing findings with community members and engaging community partners in the dissemination process. To be truly collaborative, dissemination should involve community members in a two-way dialogue about new research findings. Yet little literature describes how to engage communities in dialogue about research findings, especially with historically marginalized communities where mistrust of researchers may exist because of past or present social injustices. Through a series of interactive community presentations on findings from a longitudinal study, we developed a process for community dissemination that involved several overlapping phases: planning, outreach, content development, interactive presentations, and follow-up. Through this process, we built on existing and new community relationships. Following each interactive presentation, the research team debriefed and reviewed notes to identify lessons learned from the process. Key themes included the importance of creating a flexible dissemination plan, tailoring presentations to each community group, establishing a point person to serve as a community liaison, and continuing dialogue with community members after the presentations. Core strategies for developing trust during dissemination included engaging community members at every step, reserving ample time for discussion during presentations, building rapport by sharing personal experiences, being receptive to and learning from criticism, and implementing input from community members. This process led to a deeper understanding of research findings and ensured that results reached community members who were invested in them.

External supervision of primary healthcare facilities in low- and middle-income countries often has a managerial main purpose in which the role of support for professional development is unclear. To explore how Rwandan primary healthcare supervisors and providers (supervisees) perceive evaluative and formative functions of external supervision. Qualitative, exploratory study. Focus group discussions: three with supervisors, three with providers, and one mixed (n = 31). Findings were discussed with individual and groups of supervisors and providers. Evaluative activities occupied providers' understanding of supervision, including checking, correcting, marking and performance-based financing. These were presented as sources of motivation, that in self-determination theory indicate introjected regulation. Supervisors preferred to highlight their role in formative supervision, which may mask their own and providers' uncontested accounts that systematic performance evaluations predominated supervisors' work. Providers strongly requested larger focus on formative and supportive functions, voiced as well by most supervisors. Impact of performance evaluation on motivation and professional development is discussed. While external supervisors intended to support providers' professional development, our findings indicate serious problems with this in a context of frequent evaluations and performance marking. Separating the role of supporter and evaluator does not appear as the simple solution. If external supervision is to improve health care services, it is essential that supervisors and health centre managers are competent to support providers in a way that transparently accounts for various performance pressures. This includes delivery of proper formative supervision with useful feedback, maintaining an effective supervisory relationship, as well as ensuring providers are aware of the purpose and content of evaluative and formative supervision functions.

Microdeletions of 20q11.2 are rare but have been associated with characteristic clinical findings. A 1.6 Mb minimal critical region has been identified that includes three OMIM genes: GDF5, EPB41L1, and SAMHD. Here we describe a male monozygotic, monochorionic-diamniotic twin pair with discordant phenotypes, one with multiple findings that overlap with those reported in 20q11.2 deletions, and the other unaffected. Microarray analysis revealed mosaicism for a 363 Kb deletion encompassing GDF5 in the peripheral blood of both twins, which was confirmed by FISH. Subsequent FISH on buccal cells identified the deletion only in the affected twin. The blood FISH findings were interpreted as representing chimerism resulting from anastomosis and the blood exchange between the twins in utero. The implications of this finding are discussed, as is the contribution of GDF5 to the associated clinical findings of 20q11.2 deletions. © 2017 Wiley Periodicals, Inc.

This review article aims to discuss the pathophysiology, clinical presentation, and neuroimaging of cerebral venous thrombosis (CVT). Different approaches for diagnosis of CVT, including CT/CTV, MRI/MRV, and US will be discussed and the reader will become acquainted with imaging findings as well as limitations of each modality. Lastly, this exhibit will review the standard of care for CVT treatment and emerging endovascular options. A literature search using PubMed and the MEDLINE subengine was completed using the terms "cerebral venous thrombosis," "stroke," and "imaging." Studies reporting on the workup, imaging characteristics, clinical history, and management of patients with CVT were included. The presentation of CVT is often non-specific and requires a high index of clinical suspicion. Signs of CVT on NECT can be divided into indirect signs (edema, parenchymal hemorrhage, subarachnoid hemorrhage, and rarely subdural hematomas) and less commonly direct signs (visualization of dense thrombus within a vein or within the cerebral venous sinuses). Confirmation is performed with CTV, directly demonstrating the thrombus as a filling defect, or MRI/MRV, which also provides superior characterization of parenchymal abnormalities. General pitfalls and anatomic variants will also be discussed. Lastly, endovascular management options including thrombolysis and mechanical thrombectomy are discussed. CVT is a relatively uncommon phenomenon and frequently overlooked at initial presentation. Familiarity with imaging features and diagnostic work-up of CVT will help in providing timely diagnosis and therapy which can significantly improve outcome and diminish the risk of acute and long-term complications, optimizing patient care.

The native people of Alaska have experienced historical trauma and rapid changes in culture and lifestyle patterns. As a consequence, these populations shoulder a disproportionately high burden of psychological stress. The Yup'ik Experiences of Stress and Coping project originated from rural Yup'ik communities' concerns about stress and its effects on health. It aimed to understand the stressful experiences that affect Yup'ik communities, to identify coping strategies used to deal with these stressors and to inform culturally responsive interventions. Here, we examine the process of moving from research (gaining understanding) to disseminating project findings to translation into intervention priorities. We highlight the importance of community participation and discuss challenges encountered, strategies to address these challenges and ethical considerations for responsible intervention research with indigenous communities that reflect their unique historical and current socio-cultural realities. Community-wide presentations and discussions of research findings on stress and coping were followed by smaller Community Planning Group meetings. During these meetings, community members contextualized project findings and discussed implications for interventions. This process placed priority on community expertise in interpreting findings and translating results and community priorities into grant applications focused on intervention development and evaluation. Challenges included translation between English and Yup'ik, funding limitations and uncertainties, and the long timelines involved in moving from formative research to intervention in the face of urgent and evolving community needs. The lack of congruence between institutional and community worldviews in the intervention research enterprise highlights the need for "principled cultural sensitivity". Cultural sensitivity requires sharing results that have practical value, communicating openly, planning for sustainability and incorporating indigenous knowledge and expertise through a community-guided process. Our research findings will inform continued work within our partnership as we co-develop culturally based strategies for multilevel community interventions to address stress.

Internet-based instruction in continuing medical education (CME) has been associated with favorable outcomes. However, more direct comparative studies of different Internet-based interventions, instructional methods, presentation formats, and approaches to implementation are needed. The purpose of this study was to conduct a comparative evaluation of two Internet-based CME delivery formats and the effect on satisfaction, knowledge and confidence outcomes. Evaluative outcomes of two differing formats of an Internet-based CME course with identical subject matter were compared. A Scheduled Group Learning format involved case-based asynchronous discussions with peers and a facilitator over a scheduled 3-week delivery period. An eCME On Demand format did not include facilitated discussion and was not based on a schedule; participants could start and finish at any time. A retrospective, pre-post evaluation study design comparing identical satisfaction, knowledge and confidence outcome measures was conducted. Participants in the Scheduled Group Learning format reported significantly higher mean satisfaction ratings in some areas, performed significantly higher on a post-knowledge assessment and reported significantly higher post-confidence scores than participants in the eCME On Demand format that was not scheduled and did not include facilitated discussion activity. The findings support the instructional benefits of a scheduled delivery format and facilitated asynchronous discussion in Internet-based CME.

Red blood cell transfusions have reduced morbidity and mortality for patients with sickle cell disease. Transfusions can lead to erythrocyte alloimmunization, however, with serious complications for the patient including life-threatening delayed hemolytic transfusion reactions and difficulty in finding compatible units, which can cause transfusion delays. In this review, we discuss the risk factors associated with alloimmunization with emphasis on possible mechanisms that can trigger delayed hemolytic transfusion reactions in sickle cell disease, and we describe the challenges in transfusion management of these patients, including opportunities and emerging approaches for minimizing this life-threatening complication.

We discuss the influence of angularly selective filters on thin film gallium arsenide solar cells. For this reason, the detailed balance model was refined to fit our needs with respect to Auger recombination, reflection, transmission, and realistic absorption. For calculating real systems, an approach was made to include optical effects of angularly selective filters into electron-hole dynamic equations implemented in PC1D, a one dimensional solar cell calculation tool. With this approach, we find a relative V{sub oc} increase of 5% for an idealized 100 nm GaAs cell, including Auger recombination.

We replicated and extended the findings of Haq and Kodak (2015) by evaluating the efficiency of massed and distributed practice for teaching tacts and textual and intraverbal behavior to 3 children with autism. Massed practice included all practice opportunities conducted on 1 day during each week, and distributed practice included practice opportunities conducted across several days during the week. The results indicated that distributed practice was more efficient for all participants. Suggested areas for future research and implications for practice are discussed. © Society for the Experimental Analysis of Behavior.

Guided by a family stress perspective, we examined the hypothesis that discussing money would be associated with the handling of marital conflict in the home. Analyses were based on dyadic hierarchical linear modeling of 100 husbands’ and 100 wives’ diary reports of 748 conflict instances. Contrary to findings from previous laboratory-based surveys, spouses did not rate money as the most frequent source of marital conflict in the home. However, compared to non-money issues, marital conflicts about money were more pervasive, problematic, and recurrent, and remained unresolved, despite including more attempts at problem solving. Implications for professionals who assist couples in managing their relationships and family finances are discussed. PMID:22162622

Sexual information seeking is an important element within human information behavior. Seeking sexually related information on the Internet takes many forms and channels, including chat rooms discussions, accessing Websites or searching Web search engines for sexual materials. The study of sexual Web queries provides insight into sexually-related information-seeking behavior, of value to Web users and providers alike. We qualitatively analyzed queries from logs of 1,025,910 Alta Vista and AlltheWeb.com Web user queries from 2001. We compared the differences in sexually-related Web searching between Alta Vista and AlltheWeb.com users. Differences were found in session duration, query outcomes, and search term choices. Implications of the findings for sexual information seeking are discussed.
