    2012-02-01

    The World Trade Organization (WTO) dispute settlement procedure is a key arena for establishing global legal norms for what counts as relevant knowledge. As a high-profile case, the WTO trade dispute on GMOs mobilized scientific expertise in somewhat novel ways. Early on, the Panel put the dispute under the Sanitary and Phytosanitary (SPS) Agreement through a new legal ontology; it classified transgenes as potential pests and limited all environmental issues to the 'plant and animal health' category. The selection of scientific experts sought a multi-party consensus through a fast adversarial process, reflecting a specific legal epistemology. For the SPS framing, focusing on the defendant's regulatory procedures, the Panel staged scientific expertise in specific ways that set up how experts were questioned, the answers they would give, their specific role in the legal arena, and the way their statements would complement the Panel's findings. In these ways, the dispute settlement procedure co-produced legal and scientific expertise within the Panel's SPS framework. Moreover, the Panel operated a procedural turn in WTO jurisprudence by representing its findings as a purely legal-administrative judgement on whether the EC's regulatory procedures violated the SPS Agreement, while keeping implicit its own judgements on substantive risk issues. As this case illustrates, the WTO settlement procedure mobilizes scientific expertise for sophisticated, multiple aims: it recruits a source of credibility from the scientific arena, thus reinforcing the standard narrative of 'science-based trade discipline', while also constructing new scientific expertise for the main task--namely, challenging trade restrictions for being unduly cautious.

  3. Keeping gay and bisexual men safe: The arena of HIV prevention science and praxis.

    PubMed

    Green, Adam Isaiah

    2016-04-01

    Abstract In this article, I draw from an ongoing ethnographic study of HIV prevention for gay, bisexual, and 'men who have sex with men' to develop an institutional analysis of HIV behavioral intervention science and praxis. I approach this analysis through the lens of the social worlds framework, focusing on the institutional arena in which HIV behavioral interventions are devised and executed. Toward this end, I focus on two fundamental points of contention that lie at the heart of the prevention enterprise and put its social organization in high relief: (1) conceptions of health and lifestyle practices and (2) attributions of expertise. These core contentions reveal less the steady advance of normal science than an arena of actors ensconced in boundary work and jurisdictional struggles over how to engineer behavior change and reduce the scale of the HIV epidemic. Their resolution, I argue, has occurred in a historically contingent process determined by the political economy of the US HIV prevention arena and the differential structural location of its social worlds.

    2017-10-01

    Global recognition that the complex and multicausal problems of malnutrition require all players to collaborate and to invest towards the same objective has led to increased private sector engagement as exemplified through the Scaling Up Nutrition Business Network and mechanisms for blended financing and matched funding, such as the Global Nutrition for Growth Compact. The careful steps made over the past 5 to 10 years have however not taken away or reduced the hesitation and scepticism of the public sector actors towards commercial or even social businesses. Evidence of impact or even a positive contribution of a private sector approach to intermediate nutrition outcomes is still lacking. This commentary aims to discuss the multiple ways in which private sector can leverage its expertise to improve nutrition in general, and complementary feeding in particular. It draws on specific lessons learned in Bangladesh, Côte d'Ivoire, India, Indonesia, and Madagascar on how private sector expertise has contributed, within the boundaries of a regulatory framework, to improve availability, accessibility, affordability, and adequate use of nutritious foods. It concludes that a solid evidence base regarding the contribution of private sector to complementary feeding is still lacking and that the development of a systematic learning agenda is essential to make progress in the area of private sector engagement in nutrition. © 2017 John Wiley & Sons Ltd.

    In today's societies, where the use of sophisticated and potentially dangerous technologies has become routine and where economic and political power require the constant invention and deployment of new technologies, meaningful democratization necessarily requires that people with expertise on these subjects intervene actively in the public interest, speaking truth to power as it were. There is a long history of such intervention by scientists, physicists in particular, in debates over nuclear policies in many countries around the world. This talk will explore different roles scientists have played in this contentious and disputed arena, with some recent examples from India.

  9. The leadership team: complementary strengths or conflicting agendas?

    PubMed

    Miles, Stephen A; Watkins, Michael D

    2007-04-01

    Senior leadership teams whose members play complementary roles have been chronicled as far back as Homer's account of the Trojan War: Although King Agamemnon commanded the Greek army, Achilles, Odysseus, and Nestor each played a distinct role in defeating Troy. Today, complementary-leadership structures are common and, in some cases, even institutionalized. Think of a CEO concerned mainly with external issues and a COO who focuses internally. The authors describe four kinds of complementarity: task, expertise, cognitive, and role. The two top executives at the software company Adobe Systems, for example, represent the second kind. As CEO, Bruce Chizen draws on his sales and marketing knowledge, while COO Shantanu Narayen adds his engineering and product development expertise. Roberto Goizueta, formerly the CEO of Coca-Cola, and Douglas Ivester, his COO (who later became CEO), were famous examples of the fourth type: Goizueta, the diplomat, maintained good relations with external stakeholders; Ivester, the warrior, drove the company to defeat the competition. Bringing together two or more people with complementary strengths can compensate for the natural limitations of each. But with the benefits comes the risk of confusion, disagreement about priorities, and turf battles. Leadership succession also presents substantial challenges, especially when a COO or president who has worked in a complementary fashion with the CEO moves into the top role. An organization's board of directors and CEO can manage the risks by fostering a shared vision, common incentives, communication, and trust. They can also ensure smooth succession processes in various ways, such as brokering a gradual transfer of responsibilities or allowing the CEO and the COO to share duties as long as they maintain the logic of complementarity.

    Game playing has been a core domain of artificial intelligence research since the beginnings of the field. Game playing provides clearly defined arenas within which computational approaches can be readily compared to human expertise through head-to-head competition and other benchmarks. Game playing research has identified several simple core algorithms that provide successful foundations, with development focused on the challenges of defeating human experts in specific games. Key developments include minimax search in chess, machine learning from self-play in backgammon, and Monte Carlo tree search in Go. These approaches have generalized successfully to additional games. While computers have surpassed human expertise in a wide variety of games, open challenges remain and research focuses on identifying and developing new successful algorithmic foundations.

  13. Performance, emotion work, and transition: challenging experiences of complementary therapy student practitioners commencing clinical practice.

    PubMed

    Fixsen, Alison; Ridge, Damien

    2012-09-01

    Few researchers have explored the clinical experiences of complementary and alternative medical practitioners and students, including the emotion work they perform. In this article, using a constant comparison approach and a heuristic framework (a dramaturgical perspective), we analyze semistructured interviews with 9 undergraduate practitioners in training to examine challenges experienced when students first attend to patients. A feature of students' learning about clinical work concerned performance in a public arena and associated demands placed on the inchoate practitioner. Preliminary patient consultations represented a dramatic rite of passage and initiation into a transitional phase in professional identity. Juggling the roles of student and practitioner within an observed consultation led to anticipatory anxiety, impression management strategies, and conflict with other individuals. Of the coping strategies, participants regarded sharing and feedback from peer groups as most effective in examining and resolving the challenges of becoming a practitioner.

  14. The complementary niches of anthropocentric and biocentric conservationists.

    PubMed

    Hunter, Malcolm L; Redford, Kent H; Lindenmayer, David B

    2014-06-01

    A divergence of values has become apparent in recent debates between conservationists who focus on ecosystem services that can improve human well-being and those who focus on avoiding the extinction of species. These divergent points of view fall along a continuum from anthropocentric to biocentric values, but most conservationists are relatively closer to each other than to the ends of the spectrum. We have some concerns with both positions but emphasize that conservation for both people and all other species will be most effective if conservationists focus on articulating the values they all share, being respectful of divergent values, and collaborating on common interests. The conservation arena is large enough to accommodate many people and organizations whose diverse values lead them to different niches that can, with good will and foresight, be far more complementary than competitive. © 2014 Society for Conservation Biology.

    2013-09-01

    Cultural Historical Activity Theory served as the analytical framework for the study of a professional development event for a zoo's education department, specifically designed to build understandings of "Affective Transformation," an element pertinent to the organization's strategic plan. Three key products—an Affective Transformation model, scaffolding schematic, and definition, "providing emotional experiences for visitors which increase caring for animals and nature that may lead to zoo-related nature-protective behaviors"—emerged as a result of ongoing deliberation among professional development community members over two days. Participants, including both management- and non-management-level staff, as well as an expert facilitator, contributed complementary expertise to the process. The discussions, therefore, crossed both vertical and horizontal layers of authority. Moreover, leadership was distributed across these levels in the development of these products. Members used pre-existing resources, as well as tools created in the course of the professional development event. Interactions among participants and resources were instrumental in Affective Transformation product development. Examination of one zoo's construction of understanding of affective goals, therefore, may offer insights to other organizations with similar aspirations.

    On planet Earth, water is everywhere: the majority of the surface is covered with it; it is a key component of all life; its vapour and droplets fill the lower atmosphere; and even rocks contain it and undergo geomorphological changes because of it. A community of physical scientists largely drives studies of the chemistry of water and aqueous solutions, with expertise in biochemistry, spectroscopy and computer modelling. More recently, however, supramolecular chemists - with their expertise in macrocyclic synthesis and measuring supramolecular interactions - have renewed their interest in water-mediated non-covalent interactions. These two groups offer complementary expertise that, if harnessed, offer to accelerate our understanding of aqueous supramolecular chemistry and water writ large. This Review summarizes the state-of-the-art of the two fields, and highlights where there is latent chemical space for collaborative exploration by the two groups.

  20. Keeping experience at the bedside: the emergency consultant nurse role.

    PubMed

    Currie, Jane

    The consultant nurse concept has not yet been transferred to the military setting. The motivation for developing the role in the NHS was to improve the quality of patient care by strengthening professional leadership and extending the clinical career ladder. The consultant nurse may be defined as an expert in their clinical field, possessing expert leadership and visionary skills. The role is based on four domains: expert practice, professional leadership, education and research. Typically, the emergency consultant nurse spends 50% of their time working clinically, thereby providing senior clinical expertise and adding value to the clinical role. In a military context the consultant nurse role could be perceived as the coming together of the senior command and administrative role and the clinical role. The military has the opportunity to develop a senior clinical emergency nurse role encompassing elements of the civilian consultant nurse model, which may strengthen leadership, provide a central resource of expertise and raise the profile of military nursing. This has the added potential to provide inspiration for junior nurses and retain experienced emergency nurses in the clinical arena.

  1. Intuition, subjectivity, and Le bricoleur: cancer patients' accounts of negotiating a plurality of therapeutic options.

    PubMed

    Broom, Alex

    2009-08-01

    Cancer patients are now combining complementary and alternative medicine (CAM) with biomedical cancer treatments, reflecting an increasingly pluralistic health care environment. However, there has been little research done on the ways in which cancer patients juggle multiplicity in claims to expertise, models of disease, and therapeutic practice. Drawing on the accounts of cancer patients who use CAM, in this article I develop a conceptualization of therapeutic decision making, utilizing the notion of bricolage as a key point of departure. The patient accounts illustrate the "piecing together" (or bricolage) of therapeutic trajectories, drawing on intuitive, embodied knowledge, as well as formalized "objective" scientific expertise. Le bricoleur, as characterized here, actively mediates, rather than accepts or rejects CAM or biomedicine, and utilizes a combination of scientific expertise, embodied physicality, and social knowledge to make decisions and assess therapeutic effectiveness. Although these "border crossings" are potentially subversive of established biomedical expertise, the analysis also illustrates the structural constraints (and penalties) associated with bricolage, and furthermore, the interplay of a repositioning of responsibility with neoliberal forms of self-governance.

    Lane, Neal

    2003-04-01

    Benjamin Franklin is America's earliest model of the "civic scientist". He understood the dynamic of cross-cultural conversations, inclusive and anticipatory. Science was his passion and expertise, but society was his concern. As scientists in a much more complex world than Franklin's - we face a society and momentum that, in many ways, we as scientists have created. Just as many in our ranks have taken on the task of insuring a better informed public on scientific matters, and many have moved into policy positions in government and academic institutions, it is clearly a moment in history when more of us should actively seek that role and responsibility that was so clear to Franklin - the larger public arena.

    2009-03-01

    This article reports a multi-professional development project that was based on an action science design. The purpose was to develop 'acknowledging communication' in a psychiatric department for young people, and the objective to study the staffs' experiences of participating in the project. The professional part of the project has its foundation in Schibbye's treatment theory of inter-subjective understanding of relationships, and involves three main approaches from her theory: self-reflection, self-delimitation and emotional presence. The article presents the specific action design used, where reflection processes were developed in three different arenas: multidisciplinary Reflection groups, a Leader support group for the group leaders of the Reflection groups and collective Project seminars for all employees. A formal study programme designed to increase professional expertise, 15 European Credit Transfer System (ECTS), was also offered. The research methods included the researcher's process notes taken during the process, field notes from participating in the Leader support group, and qualitative interviews of eight informants participating in the various reflection arenas. The article presents and discusses the experiences evolved from the methods that were developed during the professional action science project: reflection on specific situations of interaction with patients in the form of oral/written narratives and the development of video presentations in combination with 'reflective teams'. The study showed that to facilitate change in the role of staff members, it is important to combine several reflection arenas where theoretical principles can be converted into practical action. By drawing data from only one study site, the study has a limited transferability, but should be of interest for professionals working with clinical change processes.

  6. Leadership mindset in mental health.

    2018-02-01

    The objective of this study was to explore the concept of mindset for psychiatrists who are considering stepping into the leadership arena. Qualitative themes were extracted from dialogue on leadership development at a Royal Australian and New Zealand College of Psychiatrists forum for early career psychiatrists. Three key themes were identified: adapting to a professional identity as psychiatrists; developing a mindset for leadership; and acting intentionally to seek opportunities for leadership. Shifts in professional identity occur in the transition from trainee to specialist as early career psychiatrists become increasingly aware of broad systemic factors in clinical care. The concept of a mindset, distinct from a skillset of knowledge and expertise, may be an emergent quality for psychiatrists who are seeking to develop their leadership potential.

  7. Direct hospital marketing: an idea whose time has come.

    1990-01-01

    Health care marketing has arrived swiftly and with significant impact upon the hospital scene. From the early days of rejection and suspicion of only a few years ago, it has now taken its place with other hospital management functions. Still, however, hospitals have not yet reached the degree of expertise that exists in other sectors. One of the reasons why hospitals have not fully emerged to the level of marketing expertise as many of their traditional business counterparts is that many of the areas of both the science and art of marketing have not been fully developed. One such area is direct mail marketing. Presented here is an overview of the advantages and functions of hospital direct mail marketing. A variety of examples are given with a more thorough case example being provided by Lee's Summit Community Hospital in Lee's Summit, Missouri. The successful direct mail marketing campaign there should be both an inspiration and a model for success for other hospitals. Space limitations prevent the authors from some of the more exacting details of mail marketing and, of course, successful campaigns do not happen by magic. They take careful planning, strategy, and execution. They also require a coordinated organizational and human effort to be successful. But direct mail marketing does offer a potentially new arena of marketing for most hospitals. The expertise, skill, knowledge, and technology are in place. All that is really needed is the commitment on the part of the hospital leadership.

    Purpose of review Although the basic standards of adjudicative competence were specified by the U.S. Supreme Court in 1960, there remain a number of complex conceptual and practical issues in interpreting and applying these standards. In this report we provide a brief overview regarding the general concept of adjudicative competence and its assessment, as well as some highlights of recent empirical studies on this topic. Findings Most adjudicative competence assessments are conducted by psychiatrists or psychologists. There are no universal certification requirements, but some states are moving toward required certification of forensic expertise for those conducting such assessments. Recent data indicate inconsistencies in application of the existing standards even among forensic experts, but the recent publication of consensus guidelines may foster improvements in this arena. There are also ongoing efforts to develop and validate structured instruments to aid competency evaluations. Telemedicine-based competency interviews may facilitate evaluation by those with specific expertise for evaluation of complex cases. There is also interest in empirical development of educational methods to enhance adjudicative competence. Summary Adjudicative competence may be difficult to measure accurately, but the assessments and tools available are advancing. More research is needed on methods of enhancing decisional capacity among those with impaired competence. PMID:18650693

    Based on the analysis of shrunken heads referred to our forensic laboratory for anthropological expertise, and data from both anthropological and medical literature, we propose a complete forensic procedure for the analysis of such pieces. A list of 14 original morphological criteria has been developed, based on the global aspect, color, physical deformation, anatomical details, and eventual associated material (wood, vegetal fibers, sand, charcoals, etc.). Such criteria have been tested on a control sample of 20 tsantsa (i.e. shrunken heads from the Jivaro or Shuar tribes of South America). Further complementary analyses are described such as CT-scan and microscopic examination. Such expertise is more and more asked to forensic anthropologists and practitioners in a context of global repatriation of human artifacts to native communities.

    Ethical analysis is crucial to decision making in biomedicine and health care, necessitating both rapid access to diffusely disseminated sources of information pertinent to bioethics and promotion of analysis in the field of bioethics through a resource for information analysis. We developed the Bioethics Discussion Forum, an Internet-based information analysis resource, in order to supplement the Bioethics Online Service with an interactive information medium to meet the demand for such an interactive resource. The Bioethics Discussion Forum has shown promise for information analysis, providing an arena for the review and discussion of complex bioethical information, establishing a connection nationally and internationally among individuals with high levels of expertise in bioethics, and providing a template for future interactive informatics services.

    Developing high-quality software is hard in the general case, and it is significantly more challenging in the case of cryptographic software. A high degree of new skill and understanding must be learnt and applied without error to avoid vulnerability and inefficiency. This is often beyond the financial, manpower or intellectual resources avail-able. In this paper we present the motivation for the European funded CACE (Computer Aided Cryptography Engineering) project The main objective of CACE is to provide engineers (with limited or no expertise in cryptography) with a toolbox that allows them to generate robust and efficient implementations of cryptographic primitives. We also present some preliminary results already obtained in the early stages of this project, and discuss the relevance of the project as perceived by stakeholders in the mobile device arena.

    2010-12-01

    Climate scientists have an important role to play in informing the public discourse on human-caused climate change. Our scientific expertise provides us a unique, informed perspective, and despite recent high profile attacks against climate science, the public still affords climate scientists the greatest trust to deliver an honest, unbiased assessment of the potential threats posed by climate changes. Yet, as with all areas of science where powerful special interests perceive themselves as threatened by the findings of science, scientists enter the public fray at our peril. Our efforts to communicate the science are opposed by a well-funded, highly organized disinformation effort that aims to confuse the public about the nature of our scientific understanding. In recent years, the disinformation campaign has demonstrated a willingness to attack individual, climate scientists as a means of achieving a broader end: discrediting climate science itself. These attacks are rarely fought in legitimate scientific circles such as the peer-reviewed scientific literature or other scholarly venues, but rather through rhetorical efforts delivered by nonscientists, using ideologically aligned media outlets, special interest groups, and politicians. Scientists are massively out-funded and outmanned in this battle, and will lose if leading scientific institutions and organizations remain on the sidelines. I will discuss this dilemma, drawing upon my own experiences in the public arena of climate change.

  15. Synergistic Allocation of Flight Expertise on the Flight Deck (SAFEdeck): A Design Concept to Combat Mode Confusion, Complacency, and Skill Loss in the Flight Deck

    This paper presents a new design and function allocation philosophy between pilots and automation that seeks to support the human in mitigating innate weaknesses (e.g., memory, vigilance) while enhancing their strengths (e.g., adaptability, resourcefulness). In this new allocation strategy, called Synergistic Allocation of Flight Expertise in the Flight Deck (SAFEdeck), the automation and the human provide complementary support and backup for each other. Automation is designed to be compliant with the practices of Crew Resource Management. The human takes a more active role in the normal operation of the aircraft without adversely increasing workload over the current automation paradigm. This designed involvement encourages the pilot to be engaged and ready to respond to unexpected situations. As such, the human may be less prone to error than the current automation paradigm.

  16. Arena geometry and path shape: when rats travel in straight or in circuitous paths?

    We show here that the global geometry of the environment affects the shape of the paths of travel in rats. To examine this, individual rats were introduced into an unfamiliar arena. One group of rats (n=8) was tested in a square arena (2 m × 2 m), and the other group (n=8) in a round arena (2 m diameter). Testing was in a total darkness, since in the absence of visual information the geometry is not perceived immediately and the extraction of environment shape is slower. We found that while the level of the rats' activity did not seem to differ between both arenas, path shape differed significantly. When traveling along the perimeter, path shape basically followed the arena walls, with perimeter paths curving along the walls of the round arena, while being straight along the walls of the square arena. A similar impact of arena geometry was observed for travel away from the arena walls. Indeed, when the rats abandoned the arena walls to crosscut through the center of the arena, their center paths were circuitous in the round arena and relatively straight in the square arena. We suggest that the shapes of these paths are exploited for the same spatial task: returning back to a familiar location in the unsighted environment. Copyright © 2011 Elsevier B.V.

    Driven by the inherent synthetic potential of CO2 as an abundant, inexpensive and renewable C1 chemical feedstock, the recent years have witnessed renewed interest in devising catalytic CO2 fixations into organic matter. Although the formation of C-C bonds via catalytic CO2 fixation remained rather limited for a long period of time, a close look into the recent literature data indicates that catalytic carboxylation reactions have entered a new era of exponential growth, evolving into a mature discipline that allows for streamlining the synthesis of carboxylic acids, building blocks of utmost relevance in industrial endeavours. These strategies have generally proven broadly applicability and convenient to perform. However, substantial challenges still need to be addressed reinforcing the need to cover metal-catalyzed carboxylation arena in a conceptual and concise manner, delineating the underlying new principles that are slowly emerging in this vibrant area of expertise. © 2018 WILEY-VCH Verlag GmbH & Co.

    Hundreds of millions of people play intellectually-demanding video games every day. What does individual performance on these games tell us about cognition? Here, we describe two studies that examine the potential link between intelligence and performance in one of the most popular video games genres in the world (Multiplayer Online Battle Arenas: MOBAs). In the first study, we show that performance in the popular MOBA League of Legends' correlates with fluid intelligence as measured under controlled laboratory conditions. In the second study, we also show that the age profile of performance in the two most widely-played MOBAs (League of Legends and DOTA II) matches that of raw fluid intelligence. We discuss and extend previous videogame literature on intelligence and videogames and suggest that commercial video games can be useful as 'proxy' tests of cognitive performance at a global population level.

    Six young deafblind adults took a 1-week course on civic engagement and advocacy, which provided the focus for a participatory action research study with a collective case study design. They selected advocacy topics, were briefed on these policy issues, and were paired with experienced mentors for meetings with legislators in Washington, DC. Eight themes were identified from constant comparative and in vivo analysis of classroom discussion notes, interviews, and journals: (a) defining advocacy and advocate, (b) rights and equality, (c) expectations, (d) role of education in change, (e) deafblind expertise, (f) characteristics of effective change agents, (g) advocacy is teamwork, (h) future advocacy. In the classroom, the participants learned about policy issues, communication considerations, and leadership, then applied this knowledge in the legislative arena. Through the advocacy process, they learned to apply their personal strengths as advocates and experienced the importance of teamwork in advocacy.

    Edith Folsom Honeycutt, now retired, is the only staff nurse in the United States to be honored by a funded chair at a major university. In 1990, a chair of oncology nursing was established in her name at Emory University by the Metropolitan Atlanta Community Foundation. A life history method was used to examine the professional life of Edith Honeycutt through interviews and with a focus group of nurses who had worked with her. Three themes emerged: teaching by showing; expecting excellent practice; and investing in each other. A synthesized overall theme of "caring in full circle" was identified as the core descriptor. The findings of this study demonstrate how clinical education and expertise are shared and learned among staff nurses. Findings also suggest how nursing knowledge can be, and is, developed at the bedside. The connection between Emory University and Edith Honeycutt demonstrates an enduring link between a university setting and a practice arena.

    Although the nursing profession has a growing role in the health policy arena, the rapidly changing health care environment means that clinicians need a sophisticated understanding of health policy. Nurses are assuming leadership roles in advocacy, research, analysis, and policy development, implementation, and evaluation, contributing to a growing need to educate nurses to specialize in health policy research and analysis. This article provides an overview of a new master's and doctoral educational program specializing in health policy for advanced practice nurses who are culturally diverse and sensitive to issues of diversity. The program, currently in its third year of operation at the University of California San Francisco, School of Nursing, is addressing the gap in nursing education and practice expertise in health policy. The program is supported through funding by the Department of Health and Human Services Health Resources and Services Administration, Advanced Nurse Training program.

    To examine the effect of ice resurfacer type on carboxyhemoglobin levels in youth hockey players. We hypothesized that players in arenas with electric resurfacers would have normal, stable carboxyhemoglobin levels during games, whereas those in arenas with internal combustion engine (IC) resurfacers would have an increase in carboxyhemoglobin levels. Prospective cohort study. Enclosed ice arenas in the northeastern United States. Convenience sample of players aged 8 to 18 years old in 16 games at different arenas. Eight arenas (37 players) used an IC ice resurfacer and 8 arenas (36 players) an electric resurfacer. Carboxyhemoglobin levels (SpCO) were measured using a pulse CO-oximeter before and after the game. Arena air was tested for carbon monoxide (CO) using a metered gas detector. Players completed symptom questionnaires. The change in SpCO from pregame to postgame was compared between players at arenas with electric versus IC resurfacers. Carbon monoxide was present at 6 of 8 arenas using IC resurfacers, levels ranged from 4 to 42 parts per million. Carbon monoxide was not found at arenas with electric resurfacers. Players at arenas with IC resurfacers had higher median pregame SpCO levels compared with those at electric arenas (4.3% vs 1%, P < 0.01). Players in the IC group also had a significant increase in their SpCO level during a hockey game compared with those in the electric group (2.8% vs 1%, P = 0.01). There were no significant differences in symptom scores. Players at arenas operating IC resurfacers had significantly higher SpCO levels. Youth hockey players in arenas with IC resurfacers have an increase in carboxyhemoglobin during games and have elevated baseline carboxyhemoglobin levels compared with players at arenas with electric resurfacers. Electric resurfacers decrease the risk of CO exposure.

    Maintaining equilibrium while riding a horse is a challenging task that involves complex sensorimotor processes. We evaluated the relative contribution of visual information (static or dynamic) to horseback riders' postural stability (measured from the variability of segment position in space) and the coordination modes they adopted to regulate balance according to their level of expertise. Riders' perceptual typologies and their possible relation to postural stability were also assessed. Our main assumption was that the contribution of visual information to postural control would be reduced among expert riders in favor of vestibular and somesthetic reliance. Twelve Professional riders and 13 Club riders rode an equestrian simulator at a gallop under four visual conditions: (1) with the projection of a simulated scene reproducing what a rider sees in the real context of a ride in an outdoor arena, (2) under stroboscopic illumination, preventing access to dynamic visual cues, (3) in normal lighting but without the projected scene (i.e., without the visual consequences of displacement) and (4) with no visual cues. The variability of the position of the head, upper trunk and lower trunk was measured along the anteroposterior (AP), mediolateral (ML), and vertical (V) axes. We computed discrete relative phase to assess the coordination between pairs of segments in the anteroposterior axis. Visual field dependence-independence was evaluated using the Rod and Frame Test (RFT). The results showed that the Professional riders exhibited greater overall postural stability than the Club riders, revealed mainly in the AP axis. In particular, head variability was lower in the Professional riders than in the Club riders in visually altered conditions, suggesting a greater ability to use vestibular and somesthetic information according to task constraints with expertise. In accordance with this result, RFT perceptual scores revealed that the Professional riders were less dependent on the visual field than were the Club riders. Finally, the Professional riders exhibited specific coordination modes that, unlike the Club riders, departed from pure in-phase and anti-phase patterns and depended on visual conditions. The present findings provide evidence of major differences in the sensorimotor processes contributing to postural control with expertise in horseback riding. PMID:28194100

    In the past decade, healthcare delivery has faced two major disruptions: the mapping of the human genome and the rise of evidence-based practice. Sociologists have documented the paradigmatic shift towards evidence-based practice in medicine, but have yet to examine its effect on other health professions or the broader healthcare arena. This article shows how evidence-based practice is transforming public health in the United States. We present an in-depth qualitative analysis of interview, ethnographic, and archival data to show how Michigan's state public health agency has navigated the turn to evidence-based practice, as they have integrated scientific advances in genomics into their chronic disease prevention programming. Drawing on organizational theory, we demonstrate how they managed ambiguity through a combination of sensegiving and sensemaking activities. Specifically, they linked novel developments in genomics to a long-accepted public health planning model, the Core Public Health Functions. This made cutting edge advances in genomics more familiar to their peers in the state health agency. They also marshaled state-specific surveillance data to illustrate the public health burden of hereditary cancers in Michigan, and to make expert panel recommendations for genetic screening more locally relevant. Finally, they mobilized expertise to help their internal colleagues and external partners modernize conventional public health activities in chronic disease prevention. Our findings show that tools and concepts from organizational sociology can help medical sociologists understand how evidence-based practice is shaping institutions and interprofessional relations in the healthcare arena.

    Comparative effectiveness research (CER) and community- based participatory research (CBPR) are two fields of research that do not have a history of strong collaboration. However, CER and CBPR researchers could benefit from interdisciplinary collaboration to design and implement relevant, timely, action-oriented research. This commentary explores field-specific definitions of stakeholders and then outlines various roles stakeholders might play within grant-funded research. Questions such as "What stakeholders should be involved?" and "How are stakeholders involved?" are addressed. The goal of this commentary is to highlight how the expertise and experiences of CBPR investigators can enhance the field of CER and to describe strategies for encouraging stakeholder involvement in CER research through the lens of CBPR. It is recommended that a team-based approach to conducting stakeholder-engaged CER encourages multiple stakeholders and "end users" to contribute their diverse expertise to the research process and contributes to the development of research with an increased likelihood of improving patient health and healthcare. © 2013 Wiley Periodicals, Inc.

    The integration of Complementary and alternative medicine (CAM) interventions into healthcare practices is becoming more popular and frequently accessed by patients. Various disciplines have integrated CAM techniques education into the preparation of their practitioners in response to this, but this varies widely, as does its success. Students'experiences of such education in pre-registration is largely unknown in the UK, and methods by which to successful achieve effective learning within this arena are largely unreported within the literature. This study highlighted three specifics aims; to examine the perspectives of pre-registration nursing students on being taught massage skills during pre-registration nurse education; to identify the learning and development that occurs during massage skills training; and to identify methods of enhancing the provision of such skills training and its experience. This paper demonstrates the value of integrating complementary therapies into nurse education, developing the holistic approach of student nurses and their concept of caring. In addition it contributes significantly to the knowledge base of the effectiveness of the value of CAM education in nurse preparation, highlighting the high value students place on CAM education and demonstrating notable development in the preparation of holistic practitioners. The method utilised also yielded ways to improve the delivery of such education, and demonstrates how creative teaching methods can motivate and enhance effective learning.

    Alcohol intoxication among spectators at sporting events and related problems, such as violence, are of great concern in many countries around the world. However, knowledge is scarce about whether or not alcohol is served to obviously intoxicated spectators at licensed premises inside and outside the sporting arenas, and if obviously intoxicated spectators are allowed entrance to these events. The objective of this study was therefore to examine the occurrences of overserving at licensed premises inside and outside arenas, and of allowed entry of obviously intoxicated spectators into arenas. An observational study assessing the rate of denied alcohol service and denied entry to arenas of trained professional actors portraying a standardized scene of obvious alcohol intoxication (i.e., pseudo-patrons) was conducted. The scene was developed by an expert panel, and each attempt was monitored by an observer. The settings were 2 arenas hosting matches in the Swedish Premier Football League in the largest city in Sweden and 1 arena in the second largest city, including entrances and licensed premises inside and outside the arenas. The rates of denied alcohol service were 66.9% at licensed premises outside the arenas (n = 151) and 24.9% at premises inside the arenas (n = 237). The rate of denied entry to the arenas (n = 102) was 10.8%. Overserving and allowed entry of obviously alcohol-intoxicated spectators are problematic at sporting events in Sweden and may contribute to high overall intoxication levels among spectators. The differences in server intervention rates indicate that serving staff at licensed premises inside the arenas and entrance staff are not likely to have been trained in responsible beverage service. This result underscores the need for server training among staff at the arenas. Copyright © 2017 by the Research Society on Alcoholism.

    Open field behavior is well known to depend on physical characteristics of the apparatus. However many of such effects are poorly described especially with using of modern methods of behavioral registration and analysis. The previous results of experiments on the effect of arena size on behavior are not numerous and contradictory. We compared the behavioral scores of four groups of C57BL/6 mice in round open field arenas of four different sizes (diameter 35, 75, 150 and 220 cm). The behavior was registered and analyzed using Noldus EthoVision, WinTrack and SegmentAnalyzer software. A significant effect of arena size was found. Traveled distance and velocity increased, but not in proportion to increase of arena size. Moreover a significant effect on segment characteristics of the trajectory was revealed. Detailed behavior analysis revealed drastic differences in trajectory structure and number of rears between smaller (35 and 75 cm) and bigger (150 and 220 cm) arenas. We conclude, that the character of exploration in smaller and bigger arenas depends on relative size of central open zone in arena. Apparently its extension increases the motivational heterogeneity of space, that requires another than in smaller arenas, strategy of exploration.

    The chronicity of chronic disease, and its associated uncertainties and fluctuations in health status, pain and/or discomfort, often leaves those so diagnosed feeling that they have lost control. Treatment can exacerbate this sense of loss of control, as people surrender to the expertise of their biomedical providers and interventions. In principle, self-management aims to return control to the individual, but its promotion is as much motivated by cost-containment as patient autonomy, and is advocated in an environment largely shaped by policy makers and biomedical providers. In this article, we examine how Australians with type 2 diabetes and/or cardiovascular disease supplement medical with complementary and alternative medical (CAM) care. Drawing on in-depth interviews with 69 participants collected in 2009-2010, we illustrate how people rely on medical providers and pharmaceuticals to manage their diabetes, but concurrently consulted with CAM practitioners and used non-biomedical therapies to enhance well-being. In explaining this, participants framed CAM use in the context of reclaiming relative personal and bodily control.

    In open field arenas, Drosophila adults exhibit a preference for arena boundaries over internal walls and open regions. Herein, we investigate the nature of this preference using phenomenological modeling of locomotion to determine whether local arena features and constraints on movement alone are sufficient to drive positional preferences within open field arenas of different shapes and with different internal features. Our model has two components: directional persistence and local wall force. In regions far away from walls, the trajectory is entirely characterized by a directional persistence probability, , for each movement defined by the step size, , and the turn angle, . In close proximity to walls, motion is computed from and a local attractive force which depends on the distance between the fly and points on the walls. The directional persistence probability was obtained experimentally from trajectories of wild type Drosophila in a circular open field arena and the wall force was computed to minimize the difference between the radial distributions from the model and Drosophila in the same circular arena. The two-component model for fly movement was challenged by comparing the positional preferences from the two-component model to wild type Drosophila in a variety of open field arenas. In most arenas there was a strong concordance between the two-component model and Drosophila. In more complex arenas, the model exhibits similar trends, but some significant differences were found. These differences suggest that there are emergent features within these complex arenas that have significance for the fly, such as potential shelter. Hence, the two-component model is an important step in defining how Drosophila interact with their environment. PMID:23071591

    Holes in netting provide potential routes for mosquitoes to enter ITNs. Despite this, there is little information on how mosquitoes respond to holes in bed nets and how their responses are affected by hole size, shape and orientation or by ambient conditions around the net. Female Anopheles gambiae (G3) were recorded in a simulated bed net consisting of two sizes of untreated netting-covered behavioural arenas placed above and beside (to simulate the bed net roof and sides respectively) the experimenter who was a source of host cues from 'inside' the net. A round hole of 9 mm or 13 mm diameter was cut into the centre of the netting of each arena. Videos of unfed female mosquitoes in arenas were analysed for time spent flying, walking and standing still and for exit through the hole. The effects of the experimenter on temperature and relative humidity around the simulated net were also measured. Mosquitoes were significantly more active in overhead arenas than in arenas to the side. Hole passage was significantly more likely in smaller arenas than larger ones and for larger holes than smaller ones. In arenas to the side, hole passage rate through small holes was about 50% less likely than what could be explained by area alone. Passage rate through holes in overhead arenas was consistent with hole area. Temperature in arenas did not strongly reflect the experimenter's presence in the simulated net. Relative humidity and absolute humidity in overhead arenas, but not in arenas to the side, were immediately affected by experimenter presence. Higher levels of activity in overhead arenas than in arenas to the side were likely due to the rising heat and humidity plume from the experimenter. Lower than expected passage rates through smaller vertically oriented holes may have been be due to an edge effect that does not apply to horizontally oriented holes. Results suggest that current methods of assessing the importance of physical damage to ITNs may not accurately reflect mosquito entry risk in all cases.

  15. Making medicine scientific: empiricism, rationality, and quackery in mid-Victorian Britain.

    1996-08-01

    This paper discusses the strategies used to construct scientific medicine in mid-Victorian Britain. An opening section considers why it was thought desirable to create a properly scientific medicine, and outlines the empirical and rational bases of the medical establishment's projects for this. The bulk of the paper concerns an alternative approach to making medicine scientific--that put forward by certain advocates of homoeopathy--and how this approach was excluded from those arenas where scientific medicine was being created, and thereby made unscientific. This process is illustrated by the clash between homoeopathy and establishment medicine that occurred in mid-Victorian Cambridge. The final section briefly considers the complementary process of educating the public in what was properly scientific medicine, and what was not, and suggests that the processes of building boundaries to exclude competing practitioners, while keeping patients inside, created the space in which modern scientific medicine has flourished so successfully.

    Contrave, under development by Orexigen Therapeutics Inc for the potential treatment of obesity, is an oral, sustained-release combination of the dopamine and norepinephrine reuptake antagonist bupropion and the opioid antagonist naltrexone. The proposed dual mechanism of action of the compound involves complementary stimulation of central melanocortin pathways, resulting in increased energy expenditure and reduced appetite. At the time of publication, Contrave was being assessed in phase III clinical trials. Preliminary data demonstrated placebo-subtracted weight losses of 3 to 7% and improvements in obesity-related comorbidities and cardiovascular risk factors. The primary adverse effect leading to discontinuation of treatment was nausea. Assuming that the results of the Contrave phase III clinical program reaffirm the efficacy and safety of the drug combination, this agent could be approved and launched to become a market leader in the anti-obesity therapeutic arena.

  17. Movement patterns of Tenebrio beetles demonstrate empirically that correlated-random-walks have similitude with a Lévy walk.

    Reynolds, Andy M; Leprêtre, Lisa; Bohan, David A

    2013-11-07

    Correlated random walks are the dominant conceptual framework for modelling and interpreting organism movement patterns. Recent years have witnessed a stream of high profile publications reporting that many organisms perform Lévy walks; movement patterns that seemingly stand apart from the correlated random walk paradigm because they are discrete and scale-free rather than continuous and scale-finite. Our new study of the movement patterns of Tenebrio molitor beetles in unchanging, featureless arenas provides the first empirical support for a remarkable and deep theoretical synthesis that unites correlated random walks and Lévy walks. It demonstrates that the two models are complementary rather than competing descriptions of movement pattern data and shows that correlated random walks are a part of the Lévy walk family. It follows from this that vast numbers of Lévy walkers could be hiding in plain sight.

  18. New Acoustic Arena Qualified at NASA Glenn's Aero-Acoustic Propulsion Laboratory

    2004-01-01

    A new acoustic arena has been qualified in the Aero-Acoustic Propulsion Laboratory (AAPL) at the NASA Glenn Research Center. This arena is outfitted specifically for conducting fan noise research with the Advanced Noise Control Fan (ANCF) test rig. It features moveable walls with large acoustic wedges (2 by 2 by 1 ft) that create an acoustic environment usable at frequencies as low as 250 Hz. The arena currently uses two dedicated microphone arrays to acquire fan inlet and exhaust far-field acoustic data. It was used successfully in fiscal year 2003 to complete three ANCF tests. It also allowed Glenn to improve the operational efficiency of the four test rigs at AAPL and provided greater flexibility to schedule testing. There were a number of technical challenges to overcome in bringing the new arena to fruition. The foremost challenge was conflicting acoustic requirements of four different rigs. It was simply impossible to construct a static arena anywhere in the facility without intolerably compromising the acoustic test environment of at least one of the test rigs. This problem was overcome by making the wall sections of the new arena movable. Thus, the arena can be reconfigured to meet the operational requirements of any particular rig under test. Other design challenges that were encountered and overcome included structural loads of the large wedges, personnel access requirements, equipment maintenance requirements, and typical time and budget constraints. The new acoustic arena improves operations at the AAPL facility in several significant ways. First, it improves productivity by allowing multiple rigs to operate simultaneously. Second, it improves research data quality by providing a unique test area within the facility that is optimal for conducting fan noise research. Lastly, it reduces labor and equipment costs by eliminating the periodic need to transport the ANCF into and out of the primary AAPL acoustic arena. The investment to design, fabricate, and install the new compact arena in fiscal year 2002 has paid dividends in fiscal year 2003 and will for many years to come. It has provided a dedicated, high-quality acoustic arena to support low-speed fan testing for ANCF while minimizing scheduling impacts and improving operational productivity in the AAPL facility.

    2005-01-01

    Integrative Medicine (IM), a newly emerging field, has evolved from Complementary and Alternative Medicine (CAM). CAM refers to diverse medical and health care systems, practices, and products that are not presently considered part of conventional medicine and generally have limited scientific evidence. In the US, CAM is a multi-billion dollar, unregulated industry with potential benefits and risks to consumers, including cancer patients, who are high utilizers of complementary therapies. Patients' CAM use often is unsupervised by physicians, yet patients need the advice and guidance of their hematologists/oncologists as part of total cancer care. Ethical and legal issues physicians need to address include inquiring about and educating patients regarding potential interactions (e.g., drug-herb, radiation-antioxidant) or product contaminants, while discussing other therapies that may alleviate symptoms and/or improve quality of life. Administratively, CAM offerings in medical settings require relevant policies and procedures, such as properly credentialing practitioners and providing financial assistance counseling for those who cannot afford fee-for-service. Unlike "Alternative Medicine," the goal of IM is to combine mainstream medical therapies and CAM therapies (e.g., acupuncture, meditation, music therapy) that have some high-quality scientific evidence of safety and effectiveness. The Society for Integrative Oncology (SIO), a new international organization of oncology professionals studying and integrating effective complementary therapies in cancer care, serves as a forum for presenting scientific data on these therapies while emphasizing the importance of developing infrastructure that promotes IM principles and practices. The ultimate goal is to develop multidisciplinary expertise and therapeutic synergy between conventional and complementary therapies.

    Drosophila adults, when placed into a novel open-field arena, initially exhibit an elevated level of activity followed by a reduced stable level of spontaneous activity and spend a majority of time near the arena edge, executing motions along the walls. In order to determine the environmental features that are responsible for the initial high activity and wall-following behavior exhibited during exploration, we examined wild-type and visually impaired mutants in arenas with different vertical surfaces. These experiments support the conclusion that the wall-following behavior of Drosophila is best characterized by a preference for the arena boundary, and not thigmotaxis or centrophobicity. In circular arenas, Drosophila mostly move in trajectories with low turn angles. Since the boundary preference could derive from highly linear trajectories, we further developed a simulation program to model the effects of turn angle on the boundary preference. In an hourglass-shaped arena with convex-angled walls that forced a straight versus wall-following choice, the simulation with constrained turn angles predicted general movement across a central gap, whereas Drosophila tend to follow the wall. Hence, low turn angled movement does not drive the boundary preference. Lastly, visually impaired Drosophila demonstrate a defect in attenuation of the elevated initial activity. Interestingly, the visually impaired w1118 activity decay defect can be rescued by increasing the contrast of the arena's edge, suggesting that the activity decay relies on visual detection of the boundary. The arena boundary is, therefore, a primary object of exploration for Drosophila. PMID:22574279

  1. How do features of dressage arenas influence training surface properties which are potentially associated with lameness?

    Results from a previous study indicated that there are specific arena surface characteristics that are associated with an increased likelihood of lameness in dressage horses. It is important to understand what modifiable arena factors lead to these detrimental surface characteristics. The aim of this study was to describe the use of training surfaces and arenas for United Kingdom dressage horses and to investigate any relationships between arena/surface variables and detrimental surface characteristics. Data from a questionnaire returned by 22.5% of all 11,363 registered members of British Dressage were used for the study. Univariate and multivariable logistic regression models were developed with each of the previously identified surface characteristics as dependent variables. Respondents reported that the majority of arenas were privately owned, sized 20 × 40 m and had a sand and rubber surface. The results indicated that wax-coated and sand and rubber surfaces were associated with less detrimental surface properties than sand, sand and PVC, woodchips or grass. Woodchips were most strongly associated with the detrimental characteristic of slipping, and sand with tripping. The findings indicated that any arena surface should have a base, with limestone the recommended surface, and that crushed concrete was best avoided. This information supported previous studies in racehorses that indicated that surface maintenance is essential, especially when many horses are using an arena daily. Problems were less likely if an arena was privately owned. Copyright © 2010. Published by Elsevier Ltd.

    2010-01-01

    The sharing of scientific data reinforces open scientific inquiry; it encourages diversity of analysis and opinion while promoting new research and facilitating the education of next generations of scientists. In this article, we present an initiative for the development of a repository containing continuous electrocardiographic information and their associated clinical information. This information is shared with the worldwide scientific community in order to improve quantitative electrocardiology and cardiac safety. First, we present the objectives of the initiative and its mission. Then, we describe the resources available in this initiative following three components: data, expertise and tools. The Data available in the Telemetric and Holter ECG Warehouse (THEW) includes continuous ECG signals and associated clinical information. The initiative attracted various academic and private partners whom expertise covers a large list of research arenas related to quantitative electrocardiography; their contribution to the THEW promotes cross-fertilization of scientific knowledge, resources, and ideas that will advance the field of quantitative electrocardiography. Finally, the tools of the THEW include software and servers to access and review the data available in the repository. To conclude, the THEW is an initiative developed to benefit the scientific community and to advance the field of quantitative electrocardiography and cardiac safety. It is a new repository designed to complement the existing ones such as Physionet, the AHA-BIH Arrhythmia Database, and the CSE database. The THEW hosts unique datasets from clinical trials and drug safety studies that, so far, were not available to the worldwide scientific community. PMID:20863512

    2015-01-01

    How did bioethics manage to grow, flourish and ultimately do so well from a very unpromising birth in the 1970s? Many explanations have been advanced. Some ascribe the field's growth to a puzzling, voluntary abnegation of moral authority by medicine to non-physicians. Some think bioethics survived by selling out to the biomedical establishment-public and private. This transaction involved bestowing moral approbation on all manner of biomedicine's doings for a seat at a well-stocked funding table. Some see a sort of clever intellectual bamboozlement at work wherein bioethicists pitched a moral elixir of objective expertise that the morally needy but unsophisticated in medicine and the biological sciences were eager to swallow. While each of these reasons has its defenders, I think the main reason that bioethics did well was that it did good. By using the media to move into the public arena, the field engaged the public imagination, provoked dialogue and debate, and contributed to policy changes that benefitted patients and healthcare providers.

  5. UFC advisor: An AI-based system for the automatic test environment

    Lincoln, David T.; Fink, Pamela K.

    1990-01-01

    The Air Logistics Command within the Air Force is responsible for maintaining a wide variety of aircraft fleets and weapon systems. To maintain these fleets and systems requires specialized test equipment that provides data concerning the behavior of a particular device. The test equipment is used to 'poke and prod' the device to determine its functionality. The data represent voltages, pressures, torques, temperatures, etc. and are called testpoints. These testpoints can be defined numerically as being in or out of limits/tolerance. Some test equipment is termed 'automatic' because it is computer-controlled. Due to the fact that effective maintenance in the test arena requires a significant amount of expertise, it is an ideal area for the application of knowledge-based system technology. Such a system would take testpoint data, identify values out-of-limits, and determine potential underlying problems based on what is out-of-limits and how far. This paper discusses the application of this technology to a device called the Unified Fuel Control (UFC) which is maintained in this manner.

  6. Global Health as a Field of Power Relations: A Response to Recent Commentaries

    PubMed Central

    Shiffman, Jeremy

    2015-01-01

    Actors working in global health often portray it as an enterprise grounded in principled concerns, advanced by individuals and organizations who draw on scientific evidence to pursue health equity. This portrait is incomplete. It is also a field of power relations—a social arena in which actors claim and draw on expertise and moral authority to gain influence and pursue career, organizational and national interests. A clear understanding of how power operates in this field is necessary to ensure that it is used productively to serve the aims of health equity and improved population health. Responding to commentaries on an editorial published in this journal, I offer 3 ideas toward this end: (1) be skeptical of the global health rationality project—the effort to rescue the field from the alleged indignities of politics through the application of scientific methods; (2) analyze global health as a field of power relations, a concept developed by sociologist Pierre Bourdieu; and (3) elevate the place of input legitimacy—inclusive deliberation, fair process and transparency—to address legitimacy and knowledge deficits in this field.

    This study aimed to evaluate the capability of performing telesurgery via radio transmission for military arenas where wired internet connections may not be practical. Most existing robotic surgery systems are too large to effectively deploy with first responders. The miniature surgical platform in this study consists of a multifunctional robot suite that can fit easily into a briefcase. The focus of this study is to explore the implications of radio control of the robot. The hypothesis is that an in vivo robot and its control boards can be controlled using off-the-shelf wireless components. An experiment was designed with off-the-shelf wireless components to test the capability of our newest generation of miniature surgical robot to become battery-operated and wireless. Wireless transmission of control signals has provided proof of concept and has exposed areas of the software that can be built upon to improve responsiveness. Wireless transmission of the video feed can be adequately performed with basic off-the-shelf components. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

  8. Radiation Brain Drain? The Impact of Demographic Change on U.S. Radiation Protection.

    2017-02-01

    The use of radiation has a substantial beneficial impact, particularly in the areas of medicine, energy production, basic science research, and industrial applications. Radiation protection knowledge and experience are required for acquiring and implementing scientific knowledge to protect workers, members of the public, and the environment from potential harmful effects of ionizing radiation while facilitating the beneficial use and development of radiation-based technologies. However, demographic changes are negatively impacting U.S. radiation protection and response capabilities. The number of radiation professionals continues to decrease even as the demand for such professionals is growing. These concerns are most pronounced in the medical, energy, research, and security arenas. Though the United States has been the world leader in radiation protection and radiation sciences for many years, the country has no strategic plan to ensure the maintenance of expertise in radiobiology, radiation physics, and radiation protection. Solving this problem will require a significant increase in federal and state funding as well as formal partnerships and initiatives among academia, professional societies, government, and the private sector.

    Kraus, Nina; Slater, Jessica

    2015-01-01

    Music and language provide an important context in which to understand the human auditory system. While they perform distinct and complementary communicative functions, music and language are both rooted in the human desire to connect with others. Since sensory function is ultimately shaped by what is biologically important to the organism, the human urge to communicate has been a powerful driving force in both the evolution of auditory function and the ways in which it can be changed by experience within an individual lifetime. This chapter emphasizes the highly interactive nature of the auditory system as well as the depth of its integration with other sensory and cognitive systems. From the origins of music and language to the effects of auditory expertise on the neural encoding of sound, we consider key themes in auditory processing, learning, and plasticity. We emphasize the unique role of the auditory system as the temporal processing "expert" in the brain, and explore relationships between communication and cognition. We demonstrate how experience with music and language can have a significant impact on underlying neural function, and that auditory expertise strengthens some of the very same aspects of sound encoding that are deficient in impaired populations. © 2015 Elsevier B.V.

    2017-01-01

    PURPOSE Population health is of growing importance in the changing health care environment. The Cooperative Extension Service, housed in each state’s land grant university, has a major impact on population health through its many community-based efforts, including the Supplemental Nutrition Assistance Program – Education (SNAP-Ed) nutrition programs, 4-H youth engagement, health and wellness education, and community development. Can the agricultural and health sectors, which usually operate in parallel, mostly unknown to each other, collaborate to address population health? We set out to provide an overview of the collaboration between the Cooperative Extension Service and the health sector in various states and describe a case study of 1 model as it developed in New Mexico. METHODS We conducted a literature review and personally contacted states in which the Cooperative Extension Service is collaborating on a “Health Extension” model with academic health centers or their health systems. We surveyed 6 states in which Health Extension models are being piloted as to their different approaches. For a case study of collaboration in New Mexico, we drew on interviews with the leadership of New Mexico State University’s Cooperative Extension Service in the College of Agricultural, Consumer and Environmental Sciences; the University of New Mexico (UNM) Health Science Center’s Office for Community Health; and the personal experiences of frontline Cooperative Extension agents and UNM Health Extension officers who collaborated on community projects. RESULTS A growing number of states are linking the agricultural Cooperative Extension Service with academic health centers and with the health care system. In New Mexico, the UNM academic health center has created “Health Extension Rural Offices” based on principles of the Cooperative Extension model. Today, these 2 systems are working collaboratively to address unmet population health needs in their communities. Nationally, the Cooperative Extension Service has formed a steering committee to guide its movement into the health arena. CONCLUSION Resources of the agricultural and health sectors offer communities complementary expertise and resources to address adverse population health outcomes. The collaboration between Cooperative Extension and the health sector is 1 manifestation of this emerging collaboration model termed Health Extension. Initial skepticism and protection of funding sources and leadership roles can be overcome with shared funding from new sources, shared priority setting and decision making, and the initiation of practical, collaborative projects that build personal relationships and trust.

  13. The circle of the soul: the role of spirituality in health care.

    PubMed

    Moss, Donald

    2002-12-01

    This paper examines the critical attitude of behavioral professionals toward spiritual phenomena, and the current growing openness toward a scientific study of spirituality and its effects on health. Health care professionals work amidst sickness and suffering, and become immersed in the struggles of suffering persons for meaning and spiritual direction. Biofeedback and neurofeedback training can facilitate relaxation, mental stillness, and the emergence of spiritual experiences. A growing body of empirical studies documents largely positive effects of religious involvement on health. The effects of religion and spirituality on health are diverse, ranging from such tangible and easily understood phenomena as a reduction of health-risk behaviors in church-goers, to more elusive phenomena such as the distant effects of prayer on health and physiology. Psychophysiological methods may prove useful in identifying specific physiological mechanisms mediating such effects. Spirituality is also a dimension in much of complementary and alternative medicine (CAM), and the CAM arena may offer a window of opportunity for biofeedback practice.

  14. Challenges To Reducing Discrimination And Health Inequity Through Existing Civil Rights Laws.

    2017-06-01

    More than fifty years after the passage of the Civil Rights Act of 1964, health care for racial and ethnic minorities remains in many ways separate and unequal in the United States. Moreover, efforts to improve minority health care face challenges that differ from those confronted during de jure segregation. We review these challenges and examine whether stronger enforcement of existing civil rights legislation could help overcome them. We conclude that stronger enforcement of existing laws-for example, through executive orders to strengthen enforcement of the laws and congressional action to allow private individuals to bring lawsuits against providers who might have engaged in discrimination-would improve minority health care, but this approach is limited in what it can achieve. Complementary approaches outside the legal arena, such as quality improvement efforts and direct transfers of money to minority-serving providers-those seeing a disproportionate number of minority patients relative to their share of the population-might prove to be more effective.

    The objective of this study was to explore barriers and facilitators influencing the integration of ethical considerations in health technology assessment (HTA). The study consisted of two complementary approaches: (a) a systematic review of the literature; and (b) an eighteen-item online survey that was distributed to fifty-six HTA agencies affiliated with the International Network of Agencies for Health Technology Assessment. The review identified twenty-six relevant articles. The most often cited barriers in the literature were: scarcity, heterogeneity and complexity of ethical analysis methods; challenges in translating ethical analysis results into knowledge that is useful for decision makers; and lack of organizational support in terms of required expertise, time and financial resources. The most frequently cited facilitators included: usage of value-based appraisal methods, stakeholder and public engagement, enhancement of practice guidelines, ethical expertise, and educational interventions. Representatives of twenty-six (46.5 percent) agencies from nineteen countries completed the survey. A median of 10 percent (interquartile range, 5 percent to 50 percent) of the HTA products produced by the agencies was reported to include an assessment of ethical aspects. The most commonly perceived barriers were: limited ethical knowledge and expertise, insufficient time and resources, and difficulties in finding ethical evidence or using ethical guidelines. Educational interventions, demand by policy makers, and involvement of ethicists in HTA were the most commonly perceived facilitators. Our results emphasize the importance of simplification of ethics methodology and development of good practice guidelines in HTA, as well as capacity building for engaging HTA practitioners in ethical analyses.

  16. Exploratory activity and habituation of Drosophila in confined domains

    2014-09-01

    Animals use locomotion to find food, shelter, and escape routes as well as to locate predators, competitors, and mates. Thus, locomotion is related to many behavioral traits, and can be used to characterize these more complex facets of behavior. Exploratory behaviors are random and need to be assessed through stochastic analysis. By comparing ensembles of trajectories from Drosophila and a model animal, we identify a pair of principles that govern the stochastic motion of a specific species. The first depends on local cues and quantify directional persistence, i.e., the propensity of an animal to maintain direction; the second, its attraction to walls, is relevant for exploration in confined arenas. Statistical properties of exploratory activity in several types of arenas can be computed from these principles. A pair of spiral arenas are designed to demonstrate that centrophobicity, or fear of the center of an arena, is not a fundamental feature of exploration. xxxx We provide evidence to show that the decay in an animal's activity following its introduction into a novel arena is correlated to its familiarity with the arena. We define two measures, coverage and habituation, to quantify familiarity. It is found that the relationship between activity and coverage is independent of the arena size. Finally, we use an analysis of exploration of mutant species to infer that in Drosophila, habituation relies on visual cues.

    2015-01-01

    A recent epidemiological study identified various aspects of arena surfaces and arena surface maintenance that were related to risk of injury in horses and that arena maintenance is important in reducing injury risk. However, there has been little research into how properties of arena surfaces change with harrowing. This study aimed to compare the properties of different arena surface types pre- and post-harrowing. The Orono Biomechanical Surface Tester fitted with accelerometers and a single- and a three-axis load cell was used to test 11 arenas with two different surfaces types, sand with rubber (SR) and waxed-sand with fibre (WSF). Three drop tests were carried out at 10 standardised locations on each arena. Mixed models were created to assess the effect of surface type, pre- or post-harrowing, and drop number on the properties of the surface, including maximum horizontal deceleration, maximum vertical deceleration, maximum vertical load and maximum horizontal load. Post-harrowing, none of the parameters were altered significantly on SR. On WSF, maximum vertical deceleration and maximum vertical load significantly decreased post-harrowing. The differences in the effects of superficial harrowing on SR and WSF could be attributed to the different compositions and sizes of the surface material. The results suggest that different maintenance techniques may be more suitable for different surface types and that the effects of superficial harrowing are short-lived due to the rapid re-compaction of the surface with repeated drops on WSF. Further work is required to determine the effects of other maintenance techniques, and on other surface types. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2016-01-01

    Adolescence is an important phase of life with increasing independence and identity development, and a vulnerable period of life for chronically ill adolescents with a high occurrence of insufficient treatment adherence. We conducted four photo elicitation focus group interviews with 14 adolescents (12-20 years) with juvenile idiopathic arthritis to investigate identity constructions during transition. Using a discourse analysis approach, six identity types were identified distributed on normal and marginal identities, which were lived either at home (home arena) or outside home with peers (out arena). Most participants positioned themselves as normal in the out arena and as ill in the home arena. Few participants positioned themselves as ill in an out arena, and they described how peers perceived this as a marginal and skewed behavior. This study contributes to a better understanding of why it can be extremely difficult to live with a chronic illness during adolescence. PMID:28462329

    Clinical post-mortem radiology is a relatively new field of expertise and not common practice in most hospitals yet. With the declining numbers of autopsies and increasing demand for quality control of clinical care, post-mortem radiology can offer a solution, or at least be complementary. A working group consisting of radiologists, pathologists and other clinical medical specialists reviewed and evaluated the literature on the diagnostic value of post-mortem conventional radiography (CR), ultrasonography, computed tomography (PMCT), magnetic resonance imaging (PMMRI), and minimally invasive autopsy (MIA). Evidence tables were built and subsequently a Dutch national evidence-based guideline for post-mortem radiology was developed. We present this evaluation of the radiological modalities in a clinical post-mortem setting, including MIA, as well as the recently published Dutch guidelines for post-mortem radiology in foetuses, neonates, and children. In general, for post-mortem radiology modalities, PMMRI is the modality of choice in foetuses, neonates, and infants, whereas PMCT is advised in older children. There is a limited role for post-mortem CR and ultrasonography. In most cases, conventional autopsy will remain the diagnostic method of choice. Based on a literature review and clinical expertise, an evidence-based guideline was developed for post-mortem radiology of foetal, neonatal, and paediatric patients. What is Known: • Post-mortem investigations serve as a quality check for the provided health care and are important for reliable epidemiological registration. • Post-mortem radiology, sometimes combined with minimally invasive techniques, is considered as an adjunct or alternative to autopsy. What is New: • We present the Dutch guidelines for post-mortem radiology in foetuses, neonates and children. • Autopsy remains the reference standard, however minimal invasive autopsy with a skeletal survey, post-mortem computed tomography, or post-mortem magnetic resonance imaging can be complementary thereof.

    Each weekend soccer arenas attract hundreds of thousands of spectators with the German Bundesliga being one of the most attractive sport series worldwide. In 2006 when the FIFA soccer World Cup™ took place in Germany, the precautions in the participating arenas against mass casualty incidents (MCI) reached a level formerly unknown in Germany. However, it is unknown how soccer arenas are prepared to deal with such incidents in everyday life. In 2011 all German major soccer league clubs were questioned about medical precautions in case of MCIs occurring in the stadium. The questionnaire included the following items: stadium capacity, the number of paramedic personnel, emergency physicians and ambulance vehicles, the command and communication structures, the availability of MCI plans, recent MCI drills and the frequency of MCI. Out of 39, 15 (38.4 %) participated, 50 % from the first league and 20.8 % from the second league. The mean stadium capacity was 41,800 spectators (minimum 10,600, maximum 80,700). Depending on the number of spectators and the individual risk score of the match the following resources were available within the stadiums (average, minimum, maximum,): emergency medical technicians 61-67 (15, 120), emergency physicians 2.3-2.5 (1, 5) and transport capacity 5.3-5.8 patients (1, 15). In 14 arenas (93.3 %) the medical personnel were trained in mass casualty care and had prepared MCI operation schedules. All stadiums had mission control centers equipped with a variety of wired and wireless communication tools, although only eight (52.3 %) arenas used a joint command structure and five (33.3 %) arenas reported MCIs (defined as a scenario involving more than 10 patients) within the past 10 years. In 40 % of the participants the last MCI-related exercise was conducted more than 36 months ago. Most of the participating arenas were adequately staffed to manage the first phase of MCIs but in contrast command structures and transport capacities often focused on individual emergencies. Although most of the participants stated that they planned the resources provision according to well established algorithms, the resources actually available at the arenas varied considerably. The frequency of MCIs in soccer arenas was surprisingly high in contrast to the frequency of MCI-related drills.

    The identification of promising hits and the generation of high quality leads are crucial steps in the early stages of drug discovery projects. The definition and assessment of both chemical and biological space have revitalized the screening process model and emphasized the importance of exploring the intrinsic complementary nature of classical and modern methods in drug research. In this context, the widespread use of combinatorial chemistry and sophisticated screening methods for the discovery of lead compounds has created a large demand for small organic molecules that act on specific drug targets. Modern drug discovery involves the employment of a wide variety of technologies and expertise in multidisciplinary research teams. The synergistic effects between experimental and computational approaches on the selection and optimization of bioactive compounds emphasize the importance of the integration of advanced technologies in drug discovery programs. These technologies (VS, HTS, SBDD, LBDD, QSAR, and so on) are complementary in the sense that they have mutual goals, thereby the combination of both empirical and in silico efforts is feasible at many different levels of lead optimization and new chemical entity (NCE) discovery. This paper provides a brief perspective on the evolution and use of key drug design technologies, highlighting opportunities and challenges.

    Public health practice will not be able in the 21st century to ignore the impact of genomics, cell and molecular biology. It will need to take into consideration issues that include, among others: the complementary nature of social and biological models of disease, genetic exceptionalism, the readiness of public and patient to respond to genomic information, the relationship between individuals and populations, and concepts of population stratification. Health systems will need to adapt their practice and organisation to include new sequencing technologies, bioinformatic expertise and proper evaluation of genetic and molecular tests. Links with the commercial sector will increase in importance. The impact on developing countries cannot be ignored and will require special attention. PMID:22488453

  8. Directional change in tunneling of subterranean termites (Isoptera: Rhinotermitidae) in response to decayed wood attractants.

    PubMed

    Su, Nan-Yao

    2005-04-01

    Wood discs decayed with brown rot fungi and polymer discs impregnated with acetone extract of decayed wood were embedded in sand of a two-dimensional foraging arena to evaluate their attractant potential in directing termite tunnels toward them. Termites were released near one arena corner and were guided to follow the physical guideline of the arena edges. In the absence of the attractants, termites generally formed a relatively linear tunnel along the edges. When decayed wood discs or treated polymer discs were placed in wet sand near one side of the arena, termite tunnels departed from the arena edges and were oriented toward them. The attraction distance ranged from 12 to 18 cm. The attractant properties were most likely water soluble and permeated through wet sand to cause termites to change their orientation. The results demonstrated that when such attractants are placed near a bait station in the field, they may be used to direct termite foraging toward the station.

    The traditional separation of the producers of research evidence in academia from the users of that evidence in healthcare organisations has not succeeded in closing the gap between what is known about the organisation and delivery of health services and what is actually done in practice. As a consequence, there is growing interest in alternative models of knowledge creation and mobilisation, ones which emphasise collaboration, active participation of all stakeholders, and a commitment to shared learning. Such models have robust historical, philosophical and methodological foundations but have not yet been embraced by many of the people working in the health sector. This paper presents an emerging model of participation, the Researcher-in-Residence. The model positions the researcher as a core member of a delivery team, actively negotiating a body of expertise which is different from, but complementary to, the expertise of managers and clinicians. Three examples of in-residence models are presented: an anthropologist working as a member of an executive team, operational researchers working in a front-line delivery team, and a Health Services Researcher working across an integrated care organisation. Each of these examples illustrates the contribution that an embedded researcher can make to a service-based team. They also highlight a number of unanswered questions about the model, including the required level of experience of the researcher and their areas of expertise, the institutional facilitators and barriers to embedding the model, and the risk that the independence of an embedded researcher might be compromised. The Researcher-in-Residence model has the potential to engage both academics and practitioners in the promotion of evidence-informed service improvement, but further evaluation is required before the model should be routinely used in practice.

    Industrial food animal production (IFAP) operations adversely impact environmental public health through air, water, and soil contamination. We sought to determine how state permitting and agriculture agencies respond to these public health concerns. We conducted semi-structured qualitative interviews with staff at 12 state agencies in seven states, which were chosen based on high numbers or rapid increase of IFAP operations. The interviews served to gather information regarding agency involvement in regulating IFAP operations, the frequency and type of contacts received about public health concerns, how the agency responds to such contacts, and barriers to additional involvement. Permitting and agriculture agencies' responses to health-based IFAP concerns are constrained by significant barriers including narrow regulations, a lack of public health expertise within the agencies, and limited resources. State agencies with jurisdiction over IFAP operations are unable to adequately address relevant public health concerns due to multiple factors. Combining these results with previously published findings on barriers facing local and state health departments in the same states reveals significant gaps between these agencies regarding public health and IFAP. There is a clear need for regulations to protect public health and for public health professionals to provide complementary expertise to agencies responsible for regulating IFAP operations.

    In this paper, we designed a reliable and image configurable flight arena, RICA, for developing cyborg bumblebees. To meet the spatial and temporal requirements of bumblebees, the Controller Area Network (CAN) bus is adopted to interconnect the LED display modules to ensure the reliability and real-time performance of the arena system. Easily-configurable interfaces on a desktop computer implemented by python scripts are provided to transmit the visual patterns to the LED distributor online and configure RICA dynamically. The new arena system will be a power tool to investigate the quantitative relationship between the visual inputs and induced flight behaviors and also will be helpful to the visual-motor research in other related fields.

    Community pharmacists play a significant role in the provision of non-prescription medicines. There is evidence that women self-medicate and use non-prescription medicines whilst breastfeeding. Studies have demonstrated that breastfeeding women are likely to seek advice from pharmacists, presenting a unique opportunity for pharmacists to provide on-going support of these women especially in relation to the appropriate use of non-prescription medicines. This study aimed to explore community pharmacists' attitudes and perspectives towards the use of non-prescription medicines during breastfeeding. This exploratory study was conducted through semi-structured interviews with 30 community pharmacists in Western Australia, between July and September 2013. Transcribed data were analysed using descriptive and qualitative approaches. NVivo ® Version 10.0 was used to organise qualitative data and quotations to facilitate thematic analysis. Four major themes emerged. Despite the positive attitudes and favourable perceived knowledge level, participants often found themselves in a dilemma when required to make clinical recommendations especially in situations where there was a therapeutic need for treatment but clear guidelines or evidence to suggest safety of the medicines or treatment in lactation was absent. Despite the popularity of complementary medicines, participants felt more confident in providing advice in relation to conventional over complementary medicines. Whilst medication safety is within the field of expertise of pharmacists, the absence of information and safety data was seen as a major challenge and barrier to enable pharmacists to confidently provide evidence-based recommendations. This study has enhanced our understanding of the attitudes and perspectives of community pharmacists towards the use of non-prescription, including complementary medicines, during breastfeeding. Future studies are warranted to confirm the safety of commonly used or requested medicines in breastfeeding. University training and continuing education for pharmacists should include the latest information available regarding the use of both conventional and complementary medicines throughout lactation.

    La presente these s'inscrit dans le cadre d'un projet strategique sur les arenas finance par le CRSNG (Conseil de Recherche en Sciences Naturelles et en Genie du Canada) qui a pour but principal le developpement d'un outil numerique capable d'estimer et d'optimiser la consommation d'energie dans les arenas et curlings. Notre travail s'inscrit comme une suite a un travail deja realise par DAOUD et coll. (2006, 2007) qui a developpe un modele 3D (AIM) en regime transitoire de l'arena Camilien Houde a Montreal et qui calcule les flux de chaleur a travers l'enveloppe du batiment ainsi que les distributions de temperatures et d'humidite durant une annee meteorologique typique. En particulier, il calcule les flux de chaleur a travers la couche de glace dus a la convection, la radiation et la condensation. Dans un premier temps nous avons developpe un modele de la structure sous la glace (BIM) qui tient compte de sa geometrie 3D, des differentes couches, de l'effet transitoire, des gains de chaleur du sol en dessous et autour de l'arena etudie ainsi que de la temperature d'entree de la saumure dans la dalle de beton. Par la suite le BIM a ete couple le AIM. Dans la deuxieme etape, nous avons developpe un modele du systeme de refrigeration (REFSYS) en regime quasi-permanent pour l'arena etudie sur la base d'une combinaison de relations thermodynamiques, de correlations de transfert de chaleur et de relations elaborees a partir de donnees disponibles dans le catalogue du manufacturier. Enfin le couplage final entre l'AIM +BIM et le REFSYS a ete effectue sous l'interface du logiciel TRNSYS. Plusieurs etudes parametriques on ete entreprises pour evaluer les effets du climat, de la temperature de la saumure, de l'epaisseur de la glace, etc. sur la consommation energetique de l'arena. Aussi, quelques strategies pour diminuer cette consommation ont ete etudiees. Le considerable potentiel de recuperation de chaleur au niveau des condenseurs qui peut reduire l'energie requise par le systeme de ventilation de l'arena a ete mis en evidence. Mots cles.

  16. Synthetic Biology between Self-Regulation and Public Discourse: Ethical Issues and the Many Roles of the Ethicist.

    PubMed

    Arnason, Gardar

    2017-04-01

    This article discusses the roles of ethicists in the governance of synthetic biology. I am particularly concerned with the idea of self-regulation of bioscience and its relationship to public discourse about ethical issues in bioscience. I will look at the role of philosophical ethicists at different levels and loci, from the "embedded ethicist" in the laboratory or research project, to ethicists' impact on policy and public discourse. In a democratic society, the development of governance frameworks for emerging technologies, such as synthetic biology, needs to be guided by a well-informed public discourse. In the case of synthetic biology, the public discourse has to go further than merely considering technical issues of biosafety and biosecurity, or risk management, to consider more philosophical issues concerning the meaning and value of "life" between the natural and the synthetic. I argue that ethicists have moral expertise to bring to the public arena, which consists not only in guiding the debate but also in evaluating arguments and moral positions and making normative judgments. When ethicists make normative claims or moral judgments, they must be transparent about their theoretical positions and basic moral standpoints.

    This research work examines the social construction of the nuclear-safety institution in France, and the concurrent increased focus on the nuclear-risk issue. Emphasis on risk and safety, as primarily technical issues, can partly be seen as a strategy. Employed by power elites in the nuclear technostructure, this diverts emphasis away from controversial and normative questions regarding the political and social consequences of technology to questions of technology that appear to be absolute to the technology itself. Nuclear safety, which started from a preoccupation with risk related to the nuclear energy research and development process, is examined using the analytic conceptmore » of field. As a social arena patterned to achieve specific tasks, this field is dominated by a body of state engineers recognized to have high-level scientific and administrative competences. It is structured by procedures and administrative hierarchies as well as by technical rules, norms, and standards. These are formalized and rationalized through technical, economic, political, and social needs; over time; they consolidate the field into an institution. The study documents the nuclear-safety institution as an integral part of the nuclear technostructure, which has historically used the specificity of its expertise as a buffer against outside interference.« less

    Miller, Perry L.

    2000-01-01

    This paper provides a “viewpoint discussion” based on a presentation made to the 2000 Symposium of the American College of Medical Informatics. It discusses potential opportunities for researchers in health informatics to become involved in the rapidly growing field of bioinformatics, using the activities of the Yale Center for Medical Informatics as a case study. One set of opportunities occurs where bioinformatics research itself intersects with the clinical world. Examples include the correlations between individual genetic variation with clinical risk factors, disease presentation, and differential response to treatment; and the implications of including genetic test results in the patient record, which raises clinical decision support issues as well as legal and ethical issues. A second set of opportunities occurs where bioinformatics research can benefit from the technologic expertise and approaches that informaticians have used extensively in the clinical arena. Examples include database organization and knowledge representation, data mining, and modeling and simulation. Microarray technology is discussed as a specific potential area for collaboration. Related questions concern how best to establish collaborations with bioscientists so that the interests and needs of both sets of researchers can be met in a synergistic fashion, and the most appropriate home for bioinformatics in an academic medical center.

    Gavin, J N

    1995-08-01

    This paper is a study of the clinical grading policy for nurses in the United Kingdom and the extent to which the participating groups in the policy development process realized their objectives. The study is based on the literature available at the time of the research and the results of structured interviews with a range of individuals involved in the policy process. The results expose the cleavages between the different representative groups on the staff side. They also shed light on the differing power bases of the groups involved. In particular, they expose the weakness of nursing as a professional pressure group and the strength of the state and its agents in determining the outcomes of policy in the public arena. It is suggested that this weakness vis-à-vis the state is responsible for the failure of nurses to achieve a reward system which recognizes the value of clinical nursing expertise, and that the 'clinical grading' system, in practice, is having the opposite effect. The policy is explored from its origins, its acceptance on to the political agenda, its negotiation and agreement, its contentious implementation, the final outcomes, and its failure to establish a valid 'clinical' pay structure.

    2014-01-01

    Current governance of regional scale water management systems in the United States has not placed them on a path toward sustainability, as conflict and gridlock characterize the social arena and ecosystem services continue to erode. Changing climate may continue this trajectory, but it also provides a catalyst for renewal of ecosystems and a window of opportunity for change in institutions. Resilience provides a bridging concept that predicts that change in ecological and social systems is often dramatic, abrupt, and surprising. Adapting to the uncertainty of climate driven change must be done in a manner perceived as legitimate by the participants in a democratic society. Adaptation must begin with the current hierarchical and fragmented social-ecological system as a baseline from which new approaches must be applied. Achieving a level of integration between ecological concepts and governance requires a dialogue across multiple disciplines, including ecologists with expertise in ecological resilience, hydrologists and climate experts, with social scientists and legal scholars. Criteria and models that link ecological dynamics with policies in complex, multi-jurisdictional water basins with adaptive management and governance frameworks may move these social-ecological systems toward greater sustainability.

    How can we leverage the successes of the numerous organizations in the climate change communication arena to build momentum rather than reinvent the wheel? Over the past two years, Climate Voices (climatevoices.org) has established a network of nearly 400 speakers and established partnerships to scale programs that address climate change communication and community engagement. In this presentation, we will present how we have identified and fostered win-win partnerships with organizations, such as GreenFaith Interfaith Partners for the Environment and Rotary International, to reach the broader general public. We will also share how, by drawing on the resources from the National Climate Assessment and the expertise of our own community, we developed and provided our speakers the tools to provide their audiences access to basic climate science - contributing to each audience's ability to understand local impacts, make informed decisions, and gain the confidence to engage in solutions-based actions in response to climate change. We will also discuss how we have created webinar coaching presentations by speakers who aren't climate scientists- and why we have chosen to do so.

  2. Global Health as a Field of Power Relations: A Response to Recent Commentaries.

    2015-05-22

    Actors working in global health often portray it as an enterprise grounded in principled concerns, advanced by individuals and organizations who draw on scientific evidence to pursue health equity. This portrait is incomplete. It is also a field of power relations-a social arena in which actors claim and draw on expertise and moral authority to gain influence and pursue career, organizational and national interests. A clear understanding of how power operates in this field is necessary to ensure that it is used productively to serve the aims of health equity and improved population health. Responding to commentaries on an editorial published in this journal, I offer 3 ideas toward this end: (1) be skeptical of the global health rationality project-the effort to rescue the field from the alleged indignities of politics through the application of scientific methods; (2) analyze global health as a field of power relations, a concept developed by sociologist Pierre Bourdieu; and (3) elevate the place of input legitimacy-inclusive deliberation, fair process and transparency-to address legitimacy and knowledge deficits in this field. © 2015 by Kerman University of Medical Sciences.

    In a global environment, education for healthcare professionals should include cultivating human resources who have the necessary skills to work in an international arena. This article will review the current status of English education for dental healthcare professionals in Japan. After conducting a literature search using the keywords: English education, Japan, and dental, only a few studies were found that investigated and proposed suggestions for dental professional English education. Even so, these were still in the early stages with outcomes yet to be fully evaluated. Even though English is thought indispensable for global professionals, and that increasing chances for communication skills is necessary, little attention has been addressed to English education for dental professionals or the implementation of such education in the Japanese undergraduate dental curricula. With the current reality of field expansion in dentistry, the need for not only improved English communication skills for Japanese dentists, but also the acquisition of essential expertise, psychomotor, teambuilding, critical thinking, and creative thinking skills in English as well as Japanese, is a definite probability. In order to reach this level of knowledge, further efforts and research would be necessary for the advancement and development of dental professional English education in Japan.

    Whether pigeons use visual landmarks for orientation from familiar locations has been a subject of debate. By recording the directional choices of both anosmic and control pigeons while exiting from a circular arena we were able to assess the relevance of olfactory and visual cues for orientation from familiar sites. When the birds could see the surroundings, both anosmic and control pigeons were homeward oriented. When the view of the landscape was prevented by screens that surrounded the arena, the control pigeons exited from the arena approximately in the home direction, while the anosmic pigeons' distribution was not different from random. Our data suggest that olfactory and visual cues play a critical, but interchangeable, role for orientation at familiar sites. PMID:11571054

    During his too short career, Olivier Chesneau pioneered the study of the circumstellar environments of low mass evolved stars using very high angular resolution techniques. He applied state of the art high angular resolution techniques, such as optical interferometry and adaptive optics imaging, to the the study of a variety of objects, from AGB stars to Planetary Nebulae, via e.g. Born Again stars, RCB stars and Novae. I present here an overview of this work and most important results by focusing on the paths he followed and key encounters he made to reach these results. Olivier liked to work in teams and was very strong at linking people with complementary expertises to whom he would communicate his enthusiasm and sharp ideas. His legacy will live on through the many people he inspired.

    2014-04-01

    Health psychology represents a context within which massage therapy research, education, and practice can be positioned for the mutual benefit of both. Furthermore, complementary and alternative medicine (CAM) more often than not plays a mediating role in relating massage therapy to health psychology. On occasion, though, the linkage between health psychology and massage therapy can be quite direct without the mediating influence of CAM. This paper, accordingly, advances a conceptual model via both flowchart and Venn diagram displays for viewing the health psychology context for massage therapy with the possibility of CAM as a mediating factor. Attention is also given to the broad range of issues constituting contemporary health psychology as well as its correspondence to an equally diverse array of client populations and health conditions addressed in massage therapy research. Future directions in the areas of health psychology, CAM, and massage therapy are proposed with a view toward a mutual and reciprocal benefit accruing to these behavioral and health science arenas.

    Internet data is introduced into public health arena under the features of fast updating and tremendous volume. Mining and analyzing internet data, researchers can model the internet-based surveillance system to assess the distribution of health-related events. There are two main types of internet-based surveillance systems, i.e. active and passive, which are distinguished by the sources of information. Through passive surveillance system, information is collected from search engine and social media while the active system gathers information through provision of the volunteers. Except for serving as a real-time and convenient complementary approach to traditional disease, food safety and adverse drug reaction surveillance program, Internet-based surveillance system can also play a role in health-related behavior surveillance and policy evaluation. Although several techniques have been applied to filter information, the accuracy of internet-based surveillance system is still bothered by the false positive information. In this article, we have summarized the development and application of internet-based surveillance system in public health to provide reference for a better surveillance program in China.

    2005-01-01

    Modern cultural trends are inclined to recognise to all human beings an always more ample right to become involved directly in choices affecting them. This even when health is concerned thus requiring expertise not always accessible to all. Informed consent to often gets reduced to a mere formality, having a mostly defensive purpose for the physician. Patients' education is becoming an ever more pressing issue in order to safeguard decision rights and the effective knowledge of the implications of every decision simultaneously. Patients' education has serious ethical implications which can't be eluded nor referred outside as happens when we let mass media inform on the advantages and disadvantages of various therapies. One of the major fields were this misinformed choice right is expressed is the so called complementary and alternative medicine. Nowadays physicians have to get back their therapeutical leadership once again, with renewed responsibility and through education as well. Information as such is a necessary and not sufficient condition. A sheer education involving the physician in a deeper as well as in an extended therapeutical alliance is needed. The challenge of taking care involves the whole human being: his/her sick body, his/her wounded feelings as well as intelligence which has to understand what is happening clearly.

    Objective To empirically investigate the ways in which patients and providers discuss Complementary and Alternative Medicine (CAM) treatment in primary care visits. Methods Audio recordings from visits between 256 adult patients aged 50 years and older and 28 primary care physicians were transcribed and analyzed using discourse analysis, an empirical sociolinguistic methodology focusing on how language is used to negotiate meaning. Results Discussion about CAM occurred 128 times in 82 of 256 visits (32.0%). The most frequently discussed CAM modalities were non-vitamin, non-mineral supplements and massage. Three physician–patient interactions were analyzed turn-by-turn to demonstrate negotiations about CAM use. Patients raised CAM discussions to seek physician expertise about treatments, and physicians adopted a range of responses along a continuum that included encouragement, neutrality, and discouragement. Despite differential knowledge about CAM treatments, physicians helped patients assess the risks and benefits of CAM treatments and made recommendations based on patient preferences for treatment. Conclusion Regardless of a physician's stance or knowledge about CAM, she or he can help patients negotiate CAM treatment decisions.

    The regular update of the guidelines on fibromyalgia syndrome, AWMF number 145/004, was scheduled for April 2017. The guidelines were developed by 13 scientific societies and 2 patient self-help organizations coordinated by the German Pain Society. Working groups (n =8) with a total of 42 members were formed balanced with respect to gender, medical expertise, position in the medical or scientific hierarchy and potential conflicts of interest. A search of the literature for systematic reviews of randomized controlled trials of complementary and alternative therapies from December 2010 to May 2016 was performed in the Cochrane library, MEDLINE, PsycINFO and Scopus databases. Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine version 2009. The strength of recommendations was formed by multiple step formalized procedures to reach a consensus. Efficacy, risks, patient preferences and applicability of available therapies were weighed up against each other. The guidelines were reviewed and approved by the board of directors of the societies engaged in the development of the guidelines. Meditative movement therapies (e.g. qi gong, tai chi and yoga) are strongly recommended. Acupuncture and weight reduction in cases of obesity can be considered.

    To empirically investigate the ways in which patients and providers discuss Complementary and Alternative Medicine (CAM) treatment in primary care visits. Audio recordings from visits between 256 adult patients aged 50 years and older and 28 primary care physicians were transcribed and analyzed using discourse analysis, an empirical sociolinguistic methodology focusing on how language is used to negotiate meaning. Discussion about CAM occurred 128 times in 82 of 256 visits (32.0%). The most frequently discussed CAM modalities were non-vitamin, non-mineral supplements and massage. Three physician-patient interactions were analyzed turn-by-turn to demonstrate negotiations about CAM use. Patients raised CAM discussions to seek physician expertise about treatments, and physicians adopted a range of responses along a continuum that included encouragement, neutrality, and discouragement. Despite differential knowledge about CAM treatments, physicians helped patients assess the risks and benefits of CAM treatments and made recommendations based on patient preferences for treatment. Regardless of a physician's stance or knowledge about CAM, she or he can help patients negotiate CAM treatment decisions. Providers do not have to possess extensive knowledge about specific CAM treatments to have meaningful discussions with patients and to give patients a framework for evaluating CAM treatment use.

  14. Agency, contract and governance: shifting shapes of accountability in the health care arena.

    PubMed

    Tuohy, Carolyn Hughes

    2003-01-01

    Current ideas about the role of the state include an enthusiasm for mechanisms of "indirect" or "third-party" governance. The health care arena, in which models of indirect governance have a long history, is an important test bed for these ideas. Classically, the arena was marked by trust-based, principal-agent relationships established to overcome information gaps. Over time (and to different degrees across nations), emphasis shifted to contractual relationships assuming relatively well-informed actors and then to performance monitoring and information sharing within complex and loosely coupled networks. In this latest stage, there is a risk that some important features of democratic leadership, and of decision making in the health care arena, will be eclipsed. Accountability mechanisms must clearly locate responsibility for actions and must allow for the exercise of professional judgment.

    Institutions Lawrence Livermore National Laboratory conduct similar or complementary research often excel through collaboration. Indeed, much of Lawrence Livermore's research involves collaboration with other institutions, including universities, other national laboratories, government agencies, and private industry. In particular, Livermore's strategic collaborations with other University of California (UC) campuses have proven exceptionally successful in combining basic science and applied multidisciplinary research. In joint projects, the collaborating institutions benefit from sharing expertise and resources as they work toward their distinctive missions in education, research, and public service. As Laboratory scientists and engineers identify resources needed to conduct their work, they often turn tomore » university researchers with complementary expertise. Successful projects can expand in scope to include additional scientists and engineers both from the Laboratory and from UC, and these projects may become an important element of the research portfolios of the cognizant Livermore directorate and the university department. Additional funding may be provided to broaden or deepen a research project or perhaps develop it for transfer to the private sector for commercial release. Occasionally, joint projects evolve into a strategic collaboration at the institutional level, attracting the attention of the Laboratory director and the UC chancellor. Government agencies or private industries may contribute funding in recognition of the potential payoff of the joint research, and a center may be established at one of the UC campuses. Livermore scientists and engineers and UC faculty are recruited to these centers to focus on a particular area and achieve goals through interdisciplinary research. Some of these researchers hold multilocation appointments, allowing them to work at Livermore and another UC campus. Such centers also attract postdoctoral researchers and graduate students pursuing careers in the centers specialized areas of science. foster university collaboration is through the Laboratory's institutes, which have been established to focus university outreach efforts in fields of scientific importance to Livermore's programs and missions. Some of these joint projects may grow to the level of a strategic collaboration. Others may assist in Livermore's national security mission; provide a recruiting pipeline from universities to the Laboratory; or enhance university interactions and the vitality of Livermore's science and technology environment through seminars, workshops, and visitor programs.« less

    The GFZ, Greifswald University and the Brandenburg University of Technology together with their partner the Polish Academy of Sciences strive for focusing their research capacities and expertise in a Helmholtz Virtual Institute for Integrated Climate and Landscape Evolution Analyses (ICLEA). The Coordination Team is based at the GFZ in Potsdam and consists of a permanent scientific manager and administrative personnel. ICLEA offers young researchers an interdisciplinary and structured education and promote their early independence through coaching and mentoring. Postdoctoral rotation positions at the ICLEA partner institutions ensure mobility of young researchers and promote dissemination of information and expertise between disciplines. Training, Research and Analytical workshops between research partners of the ICLEA virtual institute are another important measure to qualify young researchers. The long-term mission of the Virtual Institute is to provide a substantiated data basis for sustained environmental maintenance based on a profound process understanding at all relevant time scales. Aim is to explore processes of climate and landscape evolution in an historical cultural landscape extending from northeastern Germany into northwestern Poland. The northern-central European lowlands will be facilitated as a natural laboratory providing an ideal case for utilizing a systematic and holistic approach. In ICLEA five complementary work packages (WP) are established according to the key research aspects. WP 1 focus on monitoring mainly hydrology and soil moisture as well as meteorological parameters. WP 2 is linking present day and future monitoring data with the most recent past through analysing satellite images. This WP will further provide larger spatial scales. WP 3-5 focus on different natural archives to obtain a broad variety of high quality proxy data. Tree rings provide sub-seasonal data for the last centuries up to few millennia, varved lake sediments cover the entire research time interval at seasonal to decadal resolution and palaeosoils and geomorphological features also cover the entire period but not continuously and with lower resolution. Complementary information, like climate, tree ecophysiological and limnological data etc., are provided by cooperation with associated partners. Further information about ICLEA: www.iclea.de

  17. A high-fat high-sugar diet-induced impairment in place-recognition memory is reversible and training-dependent.

    A high-fat high-sugar (HFHS) diet is associated with cognitive deficits in people and produces spatial learning and memory deficits in rodents. Notable, such diets rapidly impair place-, but not object-recognition memory in rats within one week of exposure. Three experiments examined whether this impairment was reversed by removal of the diet, or prevented by pre-diet training. Experiment 1 showed that rats switched from HFHS to chow recovered from the place-recognition impairment that they displayed while on HFHS. Experiment 2 showed that control rats ("Untrained") who were exposed to an empty testing arena while on chow, were impaired in place-recognition when switched to HFHS and tested for the first time. However, rats tested ("Trained") on the place and object task while on chow, were protected from the diet-induce deficit and maintained good place-recognition when switched to HFHS. Experiment 3 examined the conditions of this protection effect by training rats in a square arena while on chow, and testing them in a rectangular arena while on HFHS. We have previously demonstrated that chow rats, but not HFHS rats, show geometry-based reorientation on a rectangular arena place-recognition task (Tran & Westbrook, 2015). Experiment 3 assessed whether rats switched to the HFHS diet after training on the place and object tasks in a square area, would show geometry-based reorientation in a rectangular arena. The protective benefit of training was replicated in the square arena, but both Untrained and Trained HFHS failed to show geometry-based reorientation in the rectangular arena. These findings are discussed in relation to the specificity of the training effect, the role of the hippocampus in diet-induced deficits, and their implications for dietary effects on cognition in people.

    The multiple partner choice arena (MPCA) is an experimental setup in which male rats display a significant shortening of ejaculation latency, which is the main characteristic of premature ejaculation (PE) in men. Thus, the MPCA is a potential animal model for PE. In this study, we further analyze whether the features of the MPCA satisfy the validity criteria for it to be considered an animal model as well as the possible participation of the serotoninergic system in the faster ejaculation exhibited by male rats in the MPCA. In Experiment 1, male rats were tested in a standard arena to assess their sexual behavior, then were assessed 1 week later in the MPCA. Another group was first tested in the MPCA, then in a standard arena. In Experiment 2, male rats divided into two groups were treated daily with WAY-100635 (5-HT(1A) antagonist) or vehicle for 15 days. In each group, half of the subjects were tested in a standard arena and half were tested in the MPCA on days 1, 8, and 15 of treatment. Number of intromissions and intromission and ejaculation latencies were the main outcome measures. In Experiment 1, males tested in the MPCA ejaculated significantly faster, regardless of the order in which they were evaluated in both arenas. In Experiment 2, the administration of WAY-100635 increased intromission and ejaculation latencies, and the number of intromissions in the MPCA. The results obtained in the MPCA support its use as an animal model for PE evaluation. © 2014 International Society for Sexual Medicine.

    For seabird species, the presence of conspecifics in a crowded breeding colony can obstruct locally available orientation cues. Thus, navigation to specific locations can present a challenging problem. We investigated short-range orientation in King Penguin (Aptenodytes patagonicus) chicks that live in a large and densely populated colony. The two main objectives were to determine whether chicks displaced to a novel location away from the colony (i) can orient towards the colony and return to their crèche and (ii) rely on visual or non-visual cues for orientation. To address these questions, a circular arena was constructed 100 m away from the colony. Chicks were released in the arena during the day and at night. After the orientation experiment in the arena, chicks were allowed to return to their home crèche, if they could. Our results showed that, during day trials, chicks preferred the half of the arena closer to the colony, but not at night. However, at night, birds spent more time on ;the colony half' of the arena if the wind blew from the colony direction. When animals were allowed to leave the arena, 98% of chicks homed during the day but only 62% of chicks homed at night. Chicks that homed at night also took longer to find their crèche. The experiments suggest that King Penguin chicks can find their crèche from a novel location. Visual cues are important for homing but, when visual cues are not present, animals are able to make use of other information carried by the wind.

    The initial phase of undergraduate engineering degree programmes often comprises courses requiring mathematical expertise which in some cases clearly exceeds school mathematics, but will be imparted only later in mathematics courses. In this article, an approach addressing this challenge by way of example within a fundamentals of electrical engineering course is presented. The concept focuses on gaining specific mathematical knowledge and competencies in the technical context of this course. For this purpose, a complementary blended learning scenario centring around a web-based learning platform and involving an adaptation of the course was developed. The concept particularly considers the heterogeneity of today's student groups and is discussed with regard to related approaches, didactical considerations, and technical implementation. For the interventions, the results of a questionnaire-based evaluation proving students' acceptance and positive influence on examination performance are presented.

    Understanding how microbiomes affect host resistance, parasite virulence, and parasite-associated diseases requires a collaborative effort between parasitologists, microbial ecologists, virologists, and immunologists. We hereby propose the Parasite Microbiome Project to bring together researchers with complementary expertise and to study the role of microbes in host-parasite interactions. Data from the Parasite Microbiome Project will help identify the mechanisms driving microbiome variation in parasites and infected hosts and how that variation is associated with the ecology and evolution of parasites and their disease outcomes. This is a call to arms to prevent fragmented research endeavors, encourage best practices in experimental approaches, and allow reliable comparative analyses across model systems. It is also an invitation to foundations and national funding agencies to propel the field of parasitology into the microbiome/metagenomic era.

    This study evaluated the predatory capacity of Euseius alatus (DeLeon) as a biological control agent of the pest mite Oligonychus ilicis (McGregor) on coffee leaves under laboratory conditions, using arenas containing 25 O. ilicis per coffee (Coffea arabica) leaf to one specimen of each stage of the predator mite. The functional response and oviposition rate of adult females of E. alatus were evaluated on coffee leaf arenas and offered from 1 to 125 immature stages of O. ilicis per arena. The number of preys killed and the number of eggs laid by the predator were evaluated every 24 h during 8 days. The preys consumed were daily replaced. Male and female adults of E. alatus were the most efficient in killing all developmental stages of O. ilicis. Larvae and nymphs of O. ilicis were the most consumed by all stages of the predatory mite. The functional response and oviposition rates of E. alatus increased as the prey density increased, with a positive and highly significant correlation. Regression analysis suggested a type II functional response, with a maximum predation of 22 O. ilicis/arena and a maximum oviposition rate of 1.7 eggs/day at a density of 70 O. ilicis/arena.

  3. The Human Capital of Knowledge Brokers: An analysis of attributes, capacities and skills of academic teaching and research faculty at Kenyan schools of public health.

    Academic faculty involved in public health teaching and research serve as the link and catalyst for knowledge synthesis and exchange, enabling the flow of information resources, and nurturing relations between 'two distinct communities' - researchers and policymakers - who would not otherwise have the opportunity to interact. Their role and their characteristics are of particular interest, therefore, in the health research, policy and practice arena, particularly in low- and middle-income countries. We investigated the individual attributes, capacities and skills of academic faculty identified as knowledge brokers (KBs) in schools of public health (SPH) in Kenya with a view to informing organisational policies around the recruitment, retention and development of faculty KBs. During April 2013, we interviewed 12 academics and faculty leadership (including those who had previously been identified as KBs) from six SPHs in Kenya, and 11 national health policymakers with whom they interact. Data were qualitatively analyzed using inductive thematic analysis to unveil key characteristics. Key characteristics of KBs fell into five categories: sociodemographics, professional competence, experiential knowledge, interactive skills and personal disposition. KBs' reputations benefitted from their professional qualifications and content expertise. Practical knowledge in policy-relevant situations, and the related professional networks, allowed KB's to navigate both the academic and policy arenas and also to leverage the necessary connections required for policy influence. Attributes, such as respect and a social conscience, were also important KB characteristics. Several changes in Kenya are likely to compel academics to engage increasingly with policymakers at an enhanced level of debate, deliberation and discussion in the future. By recognising existing KBs, supporting the emergence of potential KBs, and systematically hiring faculty with KB-specific characteristics, SPHs can enhance their collective human capital and influence on public health policy and practice. Capacity strengthening of tangible skills and recognition of less tangible personality characteristics could contribute to enhanced academic-policymaker networks. These, in turn, could contribute to the relevance of SPH research and teaching programs as well as evidence-informed public health policies.

    Experiments were conducted to examine how several key factors affect population growth of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae). Laboratory experiments were conducted to examine effects of food quantity and temperature on reproduction of cohorts of young A. tumida adults (1:1 sex ratio) housed in experimental arenas. Daily numbers and total mass of larvae exiting arenas were highly variable within treatment. Either one or two cohorts of larvae were observed exiting the arenas. Food quantity, either 10 g or 20 g, did not significantly affect the number of larvae exiting arenas at 32°C, but did at 28°C; arenas provided 20 g food produced significantly more larvae than arenas provided 10 g. Temperature did not affect the total mass of larvae provided 10 g food, but did affect larval mass provided 20 g; beetles kept at 28°C produced more larval mass than at 32°C. Field experiments were conducted to examine A. tumida reproductive success in full strength bee colonies. Beetles were introduced into hives as egg-infested frames and as adults, and some bee colonies were artificially weakened through removal of sealed brood. Efforts were unsuccessful; no larvae were observed exiting from, or during the inspection of, any hives. Possible reasons for these results are discussed. The variability observed in A. tumida reproduction even in controlled laboratory conditions and the difficulty in causing beetle infestations in field experiments involving full colonies suggest that accurately forecasting the A. tumida severity in such colonies will be difficult.

    The Iowa State University team, Team LunaCY, is composed of the following sub-teams: the main student organization, the Lunabotics Club; a senior mechanical engineering design course, ME 415; a senior multidisciplinary design course, ENGR 466; and a senior design course from Wartburg College in Waverly, Iowa. Team LunaCY designed and fabricated ART-E III, Astra Robotic Tractor- Excavator the Third, for the team's third appearance in the NASA Lunabotic Mining competition. While designing ART-E III, the team had four main goals for this year's competition:to reduce the total weight of the robot, to increase the amount of regolith simulant mined, to reduce dust, and to make ART-E III autonomous. After many designs and research, a final robot design was chosen that obtained all four goals of Team LunaCY. A few changes Team LunaCY made this year was to go to the electrical, computer, and software engineering club fest at Iowa State University to recruit engineering students to accomplish the task of making ART-E III autonomous. Team LunaCY chose to use LabView to program the robot and various sensors were installed to measure the distance between the robot and the surroundings to allow ART-E III to maneuver autonomously. Team LunaCY also built a testing arena to test prototypes and ART-E III in. To best replicate the competition arena at the Kennedy Space Center, a regolith simulant was made from sand, QuickCrete, and fly ash to cover the floor of the arena. Team LunaCY also installed fans to allow ventilation in the arena and used proper safety attire when working in the arena . With the additional practice in the testing arena and innovative robot design, Team LunaCY expects to make a strong appearance at the 2012 NASA Lunabotic Mining Competition. .

    Inhibition of GABAergic neural inputs to dorsal columns of the periaqueductal grey matter (dPAG), posterior (PH) and dorsomedial (DMH) hypothalamic nuclei elicits distinct types of escape behavioural reactions. To differentiate between the variety and intensity of panic-related behaviours, the pattern of defensive behaviours evoked by blockade of GABAA receptors in the DMH, PH and dPAG were compared in a circular open-field test and in a recently designed polygonal arena. In the circular open-field, the defensive behaviours induced by microinjection of bicuculline into DMH and PH were characterised by defensive alertness behaviour and vertical jumps preceded by rearing exploratory behaviour. On the other hand, explosive escape responses interspersed with horizontal jumps and freezing were observed after the blockade of GABAA receptors on dPAG neurons. In the polygonal arena apparatus, the escape response produced by GABAergic inhibition of DMH and PH neurons was directed towards the burrow. In contrast, the blockade of GABAA receptors in dPAG evoked non-oriented escape behaviour characterised by vigorous running and horizontal jumps in the arena. Our findings support the hypothesis that the hypothalamic nuclei organise oriented escape behavioural responses whereas non-oriented escape is elaborated by dPAG neurons. Additionally, the polygonal arena with a burrow made it easy to discriminate and characterise these two different patterns of escape behavioural responses. In this sense, the polygonal arena with a burrow can be considered a good methodological tool to discriminate between these two different patterns of escape behavioural responses and is very useful as a new experimental animal model of panic attacks.

    Biorepositories offer tremendous scientific value to a wide variety of customer groups (academic, commercial, industrial) in their ability to deliver a centralized, standardized service model, encompassing both biospecimen storage and related laboratory services. Generally, the scientific expertise and economies of scale that are offered in centralized, properly resourced research biobanks has yielded value that has been well-recognized by universities, pharmaceutical companies, and other sponsoring institutions. However, like many facets of the economy, biobanks have been under increasing cost pressure in recent years. This has been a particular problem in the academic arena, where direct support from grant sources (both governmental and philanthropic) typically now is more difficult to secure, or provides reduced financial support, relative to previous years. One way to address this challenge is to establish or enhance a well-defined fee-for-service model which is properly calibrated to cover operational costs while still offering competitive value to users. In this model, customers are never charged for the biospecimens themselves, but rather for the laboratory services associated with them. Good communication practices, proper assessment of value, implementation of best practices, and a sound business plan are all needed for this initiative to succeed. Here we summarize our experiences at Washington University School of Medicine in the expectation they will be useful to others.

    Physical exercise is useful for individuals with mental disorders with additional substance dependency or abuse. Many exercise actively while in institution, but a major challenge is to continue after discharge. Many patients are isolated and lonely and find it hard to motivate themselves to exercise on their own. In Sogn og Fjordane county, Norway, the problem was dealt with through a training program of exercise contacts. These are social support persons who were thus assigned a new function. By way of a 40-hour course that covered physical activity, psychological problems, and substance abuse and dependency, lay people were trained to help people in their home environment. By the end of 2005, almost 300 exercise contacts, living in 25 of the 26 municipalities in the county, had passed the course exam. Their expertise is highly demanded and more courses have been requested. The course evaluations have been quite positive. In particular, the practical instructions about how to exercise, in combination with updated theory on substance abuse/dependence and mental disorders, were highly appreciated. Clients were helped to continue with regular physical activity and they have appreciated the improved physical and mental health that was associated with regular exercise. Moreover, the exercise contacts help clients break social isolation and have given them access to the common social arenas.

    The traditional separation of the producers of research evidence in academia from the users of that evidence in healthcare organisations has not succeeded in closing the gap between what is known about the organisation and delivery of health services and what is actually done in practice. As a consequence, there is growing interest in alternative models of knowledge creation and mobilisation, ones which emphasise collaboration, active participation of all stakeholders, and a commitment to shared learning. Such models have robust historical, philosophical and methodological foundations but have not yet been embraced by many of the people working in the health sector. This paper presents an emerging model of participation, the Researcher-in-Residence. The model positions the researcher as a core member of a delivery team, actively negotiating a body of expertise which is different from, but complementary to, the expertise of managers and clinicians. Three examples of in-residence models are presented: an anthropologist working as a member of an executive team, operational researchers working in a front-line delivery team, and a Health Services Researcher working across an integrated care organisation. Each of these examples illustrates the contribution that an embedded researcher can make to a service-based team. They also highlight a number of unanswered questions about the model, including the required level of experience of the researcher and their areas of expertise, the institutional facilitators and barriers to embedding the model, and the risk that the independence of an embedded researcher might be compromised. The Researcher-in-Residence model has the potential to engage both academics and practitioners in the promotion of evidence-informed service improvement, but further evaluation is required before the model should be routinely used in practice.

    Mass gathering events in sports arenas create challenges regarding the cardiovascular safety of both athletes and spectators. A comprehensive medical action plan, to ensure properly applied cardiopulmonary resuscitation, and wide availability and use of automated external defibrillators (AEDs), is essential to improving survival from sudden cardiac arrest at sporting events. This paper outlines minimum standards for cardiovascular care to assist in the planning of mass gathering sports events across Europe with the intention of local adaptation at individual sports arenas, to ensure the full implementation of the chain of survival.

    Drosophila melanogaster has become an important invertebrate model organism in biological and medical research, for mutational and genetic analysis, and in toxicological screening. Many screening assays have been developed that assess the flies' mortality, reproduction, development, morphology, or behavioral competence. In this study, we describe a new assay for locomotor competence. It comprises a circular walking arena with a lenticular floor and a flat cover (the slope of the floor increases gradually from the center to the edge of the arena) plus automated fly tracking and statistical analysis. This simple modification of a flat arena presents a graduated physical challenge, with which we can assess fine gradations of motor ability, since a fly's time average radial distance from the arena center is a direct indicator of its climbing ability. The time averaged distribution of flies as a function of slope, activity levels, and walking speed, yields a fine grained picture of locomotory ability and motivation levels. We demonstrate the strengths and weaknesses of this assay (compared with a conventional tap-down test) by observing flies treated with a neurotoxin (BMAA) that acts as a glutamate agonist. The assay proves well suited to detect dose effects and progression effects with higher statistical power than the traditional tap-down, but it has a higher detection limit, making it less sensitive to treatment effects. © 2012 WILEY PERIODICALS, INC.

  18. Sibling competition arena: selfing and a competition arena can combine to constitute a barrier to gene flow in sympatry.

    Gibson, A K; Hood, M E; Giraud, T

    2012-06-01

    Closely related species coexisting in sympatry provide critical insight into the mechanisms underlying speciation and the maintenance of genetic divergence. Selfing may promote reproductive isolation by facilitating local adaptation, causing reduced hybrid fitness in parental environments. Here, we propose a novel mechanism by which selfing can further impair interspecific gene flow: selfing may act to ensure that nonhybrid progeny systematically co-occur whenever hybrid genotypes are produced. Under a competition arena, the fitness differentials between nonhybrid and hybrid progeny are then magnified, preventing development of interspecific hybrids. We investigate whether this "sibling competition arena" can explain the coexistence in sympatry of closely related species of the plant fungal pathogens (Microbotryum) causing anther-smut disease. The probabilities of intrapromycelial mating (automixis), outcrossing, and sibling competition were manipulated in artificial inoculations to evaluate their contribution to reproductive isolation. We report that both intrapromycelial selfing and sibling competition significantly reduced rates of hybrid infection beyond that expected based solely upon selfing rates and noncompetitive fitness differentials between hybrid and nonhybrid progeny. Our results thus suggest that selfing and a sibling competition arena can combine to constitute a barrier to gene flow and diminish selection for additional barriers to gene flow in sympatry. © 2012 The Author(s). Evolution © 2012 The Society for the Study of Evolution.

  17. Exposure to nitrogen dioxide in an indoor ice arena - New Hampshire, 2011.

    PubMed

    2012-03-02

    In January 2011, the New Hampshire Department of Health and Human Services (NHDHHS) investigated acute respiratory symptoms in a group of ice hockey players. The symptoms, which included cough, shortness of breath, hemoptysis, and chest pain or tightness, were consistent with exposure to nitrogen dioxide gas (NO), a byproduct of combustion. Environmental and epidemiologic investigations were begun to determine the source of the exposure and identify potentially exposed persons. This report summarizes the results of those investigations, which implicated a local indoor ice arena that had hosted two hockey practice sessions during a 24-hour period when the arena ventilation system was not functioning. A total of 43 exposed persons were interviewed, of whom 31 (72.1%) reported symptoms consistent with NO exposure. The highest attack rate was among the hockey players (87.9%). After repair of the ventilation system, no additional cases were identified. To prevent similar episodes, ice arena operators should ensure ventilation systems and alarms are operating properly and that levels of NO and carbon monoxide (CO) are monitored continuously for early detection of increased gas levels.

  18. Shape shifting: Local landmarks interfere with navigation by, and recognition of, global shape.

    PubMed

    Buckley, Matthew G; Smith, Alastair D; Haselgrove, Mark

    2014-03-01

    An influential theory of spatial navigation states that the boundary shape of an environment is preferentially encoded over and above other spatial cues, such that it is impervious to interference from alternative sources of information. We explored this claim with 3 intradimensional-extradimensional shift experiments, designed to examine the interaction of landmark and geometric features of the environment in a virtual navigation task. In Experiments 1 and 2, participants were first required to find a hidden goal using information provided by the shape of the arena or landmarks integrated into the arena boundary (Experiment 1) or within the arena itself (Experiment 2). Participants were then transferred to a different-shaped arena that contained novel landmarks and were again required to find a hidden goal. In both experiments, participants who were navigating on the basis of cues that were from the same dimension that was previously relevant (intradimensional shift) learned to find the goal significantly faster than participants who were navigating on the basis of cues that were from a dimension that was previously irrelevant (extradimensional shift). This suggests that shape information does not hold special status when learning about an environment. Experiment 3 replicated Experiment 2 and also assessed participants' recognition of the global shape of the navigated arenas. Recognition was attenuated when landmarks were relevant to navigation throughout the experiment. The results of these experiments are discussed in terms of associative and non-associative theories of spatial learning.

  19. Modeling Novelty Habituation During Exploratory Activity in Drosophila

    PubMed Central

    Soibam, Benjamin; Shah, Shishir; Gunaratne, Gemunu H.; Roman, Gregg W.

    2013-01-01

    Habituation is a common form of non-associative learning in which the organism gradually decreases its response to repeated stimuli. The decrease in exploratory activity of many animal species during exposure to a novel open field arena is a widely studied habituation paradigm. However, a theoretical framework to quantify how the novelty of the arena is learned during habituation is currently missing. Drosophila melanogaster display a high mean absolute activity and a high probability for directional persistence when first introduced to a novel arena. Both measures decrease during habituation to the arena. Here, we propose a phenomenological model of habituation for Drosophila exploration based on two principles: Drosophila form a spatial representation of the arena edge as a set of connected local patches, and repeated exposure to these patches is essential for the habituation of the novelty. The level of exposure depends on the number of visitations and is quantified by a variable referred to as “coverage.” This model was tested by comparing predictions against the experimentally measured behavior of wild type Drosophila. The novelty habituation of wild type Canton-S depends on coverage and is specifically independent of the arena radius. Our model describes the time dependent locomotor activity, ΔD, of Canton-S using an experimentally established stochastic process Pn(ΔD) which depends on the coverage. The quantitative measures of exploration and habituation were further applied to three mutant genotypes. Consistent with a requirement for vision in novelty habituation, blind no receptor potential A7 mutants display a failure in the decay of probability for directional persistence and mean absolute activity. The rutabaga2080 habituation mutant also shows defects in these measures. The kurtz1 non-visual arrestin mutant demonstrates a rapid decay in these measures, implying reduced motivation. The model and the habituation measures offer a powerful framework for understanding mechanisms associated with open field habituation. PMID:23597866

    2014-07-01

    The population's attitude towards smoking bans in public arenas is important for their passing, implementation and compliance. Smoking bans are believed to reduce the social acceptability of smoking, and once people experience them, public support increases--also among pre-ban sceptics. This study aimed to examine the temporal changes in public attitude towards smoking bans in public arenas from 2007 to 2010 and whether these changes differed across educational attainment, smoking status and intention to quit among smokers. Data from two surveys among adults (aged 25-79 years) in 2007 and 2010 in the Capital Region of Denmark (n=36,472/42,504, response rate = 52.3) was linked with data on sex, age and educational attainment from central registers. Age-standardised prevalence of supportive attitude towards smoking bans was estimated. Temporal changes in supportive attitude were explored in workplaces, restaurants and bars using logistic regression models. The prevalence of supportive attitude towards smoking bans increased significantly in all arenas from 2007 to 2010. Positive temporal changes in supportive attitude towards smoking bans were seen across educational attainment, smoking status and intention to quit smoking in restaurants and across smoking status for smoking bans in workplaces and bars. The results of this study show that the public's attitude towards smoking in public arenas has changed after the implementation of a comprehensive smoking ban. This change in attitude can support implementation of future legislation on smoking and may lead to positive changes in smoking norms. © 2014 the Nordic Societies of Public Health.

    Kulikov, Alexander V; Tikhonova, Maria A; Kulikov, Victor A

    2008-05-30

    New modification of the open field was designed to improve automation of the test. The main innovations were: (1) transmitted lighting and (2) estimation of probability to find pixels associated with an animal in the selected region of arena as an objective index of spatial preference. Transmitted (inverted) lighting significantly ameliorated the contrast between an animal and arena and allowed to track white animals with similar efficacy as colored ones. Probability as a measure of preference of selected region was mathematically proved and experimentally verified. A good correlation between probability and classic indices of spatial preference (number of region entries and time spent therein) was shown. The algorithm of calculation of probability to find pixels associated with an animal in the selected region was implemented in the EthoStudio software. Significant interstrain differences in locomotion and the central zone preference (index of anxiety) were shown using the inverted lighting and the EthoStudio software in mice of six inbred strains. The effects of arena shape (circle or square) and a novel object presence in the center of arena on the open field behavior in mice were studied.

    With an estimated backlog of 4,000,000 patients worldwide, cleft lip and cleft palate remain a stark example of the global burden of surgical disease. The need for a new paradigm in global surgery has been increasingly recognized by governments, funding agencies, and professionals to exponentially expand care while emphasizing safety and quality. This three-part article examines the evolution of the Operation Smile Guwahati Comprehensive Cleft Care Center (GCCCC) as an innovative model for sustainable cleft care in the developing world. The GCCCC is the result of a unique public-private partnership between government, charity, and private enterprise. In 2009, Operation Smile, the Government of Assam, the National Rural Health Mission, and the Tata Group joined together to work towards the common goal of creating a center of excellence in cleft care for the region. This partnership combined expertise in medical care and training, organizational structure and management, local health care infrastructure, and finance. A state-of-the-art surgical facility was constructed in Guwahati, Assam which includes a modern integrated operating suite with an open layout, advanced surgical equipment, sophisticated anesthesia and monitoring capabilities, central medical gases, and sterilization facilities. The combination of established leaders and dreamers from different arenas combined to create a synergy of ambitions, resources, and compassion that became the backbone of success in Guwahati.

  14. Fee-For-Service as a Business Model of Growing Importance: The Academic Biobank Experience

    PubMed Central

    2012-01-01

    Biorepositories offer tremendous scientific value to a wide variety of customer groups (academic, commercial, industrial) in their ability to deliver a centralized, standardized service model, encompassing both biospecimen storage and related laboratory services. Generally, the scientific expertise and economies of scale that are offered in centralized, properly resourced research biobanks has yielded value that has been well-recognized by universities, pharmaceutical companies, and other sponsoring institutions. However, like many facets of the economy, biobanks have been under increasing cost pressure in recent years. This has been a particular problem in the academic arena, where direct support from grant sources (both governmental and philanthropic) typically now is more difficult to secure, or provides reduced financial support, relative to previous years. One way to address this challenge is to establish or enhance a well-defined fee-for-service model which is properly calibrated to cover operational costs while still offering competitive value to users. In this model, customers are never charged for the biospecimens themselves, but rather for the laboratory services associated with them. Good communication practices, proper assessment of value, implementation of best practices, and a sound business plan are all needed for this initiative to succeed. Here we summarize our experiences at Washington University School of Medicine in the expectation they will be useful to others. PMID:23386922

    Abstract Background: This commentary presents the most impactful, shared priorities for research investment across the licensed complementary and integrative health (CIH) disciplines according to the Academic Consortium for Complementary and Alternative Health Care (ACCAHC). These are (1) research on whole disciplines; (2) costs; and (3) building capacity within the disciplines' universities, colleges, and programs. The issue of research capacity is emphasized. Discussion: ACCAHC urges expansion of investment in the development of researchers who are graduates of CIH programs, particularly those with a continued association with accredited CIH schools. To increase capacity of CIH discipline researchers, we recommend National Center for Complementary and Integrative Health (NCCIH) to (1) continue and expand R25 grants for education in evidence-based healthcare and evidence-informed practice at CIH schools; (2) work to limit researcher attrition from CIH institutions by supporting career development grants for clinicians from licensed CIH fields who are affiliated with and dedicated to continuing to work in accredited CIH schools; (3) fund additional stand-alone grants to CIH institutions that already have a strong research foundation, and collaborate with appropriate National Institutes of Health (NIH) institutes and centers to create infrastructure in these institutions; (4) stimulate higher percentages of grants to conventional centers to require or strongly encourage partnership with CIH institutions or CIH researchers based at CIH institutions, or give priority to those that do; (5) fund research conferences, workshops, and symposia developed through accredited CIH schools, including those that explore best methods for studying the impact of whole disciplines; and (6) following the present NIH policy of giving priority to new researchers, we urge NCCIH to give a marginal benefit to grant applications from CIH clinician-researchers at CIH academic/research institutions, to acknowledge that CIH concepts require specialized expertise to translate to conventional perspectives. Summary: We commend NCCIH for its previous efforts to support high-quality research in the CIH disciplines. As NCCIH develops its 2016–2020 strategic plan, these recommendations to prioritize research based on whole disciplines, encourage collection of outcome data related to costs, and further support capacity-building within CIH institutions remain relevant and are a strategic use of funds that can benefit the nation's health.

    Solid organ and cell transplantation, including pancreatic islets constitute the treatment of choice for chronic terminal diseases. However, the clinical use of allogeneic transplantation is limited by the growing shortage of human organs. This has prompted us to initiate a unique multi-center and multi-team effort to promote translational research in xenotransplantation to bring xenotransplantation to the clinical setting. Supported by the German Research Foundation, an interdisciplinary group of surgeons, internal medicine doctors, diabetologists, material sciences experts, immunologists, cell biologists, virologists, veterinarians, and geneticists have established a collaborative research center (CRC) focusing on the biology of xenogeneic cell, tissue, and organ transplantation. A major strength of this consortium is the inclusion of members of the regulatory bodies, including the Paul-Ehrlich Institute (PEI), infection specialists from the Robert Koch Institute and PEI, veterinarians from the German Primate Center, and representatives of influential ethical and religious institutions. A major goal of this consortium is to promote islet xenotransplantation, based on the extensive expertise and experience of the existing clinical islet transplantation program. Besides comprehensive approaches to understand and prevent inflammation-mediated islet xenotransplant dysfunction [immediate blood-mediated inflammatory reaction (IBMIR)], we also take advantage of the availability of and experience with islet macroencapsulation, with the goal to improve graft survival and function. This consortium harbors a unique group of scientists with complementary expertise under a cohesive program aiming at developing new therapeutic approaches for islet replacement and solid organ xenotransplantation. © Georg Thieme Verlag KG Stuttgart · New York.

  20. Differential effects of exposure to low-light or high-light open-field on anxiety-related behaviors; relationship to c-Fos expression in serotonergic and non-serotonergic neurons in the dorsal raphe nucleus

    Serotonergic systems arising from the mid-rostrocaudal and caudal dorsal raphe nucleus (DR) have been implicated in the facilitation of anxiety-related behavioral responses by anxiogenic drugs or aversive stimuli. In this study we attempted to determine a threshold to engage serotonergic neurons in the DR following exposure to aversive conditions in an anxiety-related behavioral test. We manipulated the intensity of anxiogenic stimuli in studies of male Wistar rats by leaving them undisturbed (CO), briefly handling them (HA), or exposing them to an open-field arena for 15-min under low-light (LL: 8-13 lux) or high-light (HL: 400-500 lux) conditions. Rats exposed to HL conditions responded with reduced locomotor activity, reduced time spent exploring the center of the arena, a lower frequency of rearing and grooming, and an increased frequency of facing the corner of the arena compared to LL rats. Rats exposed to HL conditions had small but significant increases in c-Fos expression within serotonergic neurons in subdivisions of the rostral DR. Exposure to HL conditions did not alter c-Fos responses in serotonergic neurons in any other DR subdivision. In contrast, rats exposed to the open-field arena had increased c-Fos expression in non-serotonergic cells throughout the DR compared to CO rats, and this effect was particularly apparent in the dorsolateral part of the DR. We conclude that exposure to HL conditions, compared to LL conditions, increased anxiety-related behavioral responses in an open-field arena but this stimulus was at or below the threshold required to increase c-Fos expression in serotonergic neurons.

  1. Path planning on cellular nonlinear network using active wave computing technique

    2009-05-01

    This paper introduces a simple algorithm to solve robot path finding problem using active wave computing techniques. A two-dimensional Cellular Neural/Nonlinear Network (CNN), consist of relaxation oscillators, has been used to generate active waves and to process the visual information. The network, which has been implemented on a Field Programmable Gate Array (FPGA) chip, has the feature of being programmed, controlled and observed by a host computer. The arena of the robot is modelled as the medium of the active waves on the network. Active waves are employed to cover the whole medium with their own dynamics, by starting from an initial point. The proposed algorithm is achieved by observing the motion of the wave-front of the active waves. Host program first loads the arena model onto the active wave generator network and command to start the generation. Then periodically pulls the network image from the generator hardware to analyze evolution of the active waves. When the algorithm is completed, vectorial data image is generated. The path from any of the pixel on this image to the active wave generating pixel is drawn by the vectors on this image. The robot arena may be a complicated labyrinth or may have a simple geometry. But, the arena surface always must be flat. Our Autowave Generator CNN implementation which is settled on the Xilinx University Program Virtex-II Pro Development System is operated by a MATLAB program running on the host computer. As the active wave generator hardware has 16, 384 neurons, an arena with 128 × 128 pixels can be modeled and solved by the algorithm. The system also has a monitor and network image is depicted on the monitor simultaneously.

    2000-03-01

    The repellency of N,N-diethyl-3-methylbenzamide (deet) to Triatoma infestans (Klug) (Hemiptera: Reduviidae) was evaluated using third-instar nymphs and a video tracking technique. Three experimental designs were used: (a) the test arena floor was divided into two halves, only one of which was treated with deet; (b) the arena floor was divided into an inner circle and an outer ring, only the latter treated with deet; (c) half of the test arena was covered by a filter paper roof treated with deet (out of reach of the nymphs). In all three types of experiment, a repellent effect was demonstrated proportional to the dose of deet. When a host (pigeon) was shielded by deet-treated gauze, the rate of blood-feeding by the nymphs was inhibited. Topical pre-treatment of the nymphs with N-ethylmaleimide, to block chemoreception, inhibited the repellency.

    This article presents a model that integrates three branches of research: (i) economics of solid waste that assesses consumer's willingness to recycle and to pay for disposal; (ii) economics of solid waste that compares private and social costs of final disposal and recycling; and (iii) theories on personal attitudes and social influence. The model identifies two arenas where decisions are made: upstream arena, where residents are decision-makers, and downstream arena, where municipal authorities are decision-makers, and graphically proposes interactions between disposal and recycling, as well as the concept of 'constrained recycling' (an alternative to optimal recycling) to guide policy design. It finally concludes that formative instruments, such as environmental education and benchmarks, should be combined with economic instruments, such as subsidies, to move constraints on source separation and recycling in the context of developing countries.

    2009-01-01

    Three experiments established the effectiveness of an Automated Remote Environmental Navigation Apparatus (ARENA) developed in our lab to study behavioral processes in pigeons. The technology utilizes one or more wireless modules, each capable of presenting colored lights as visual stimuli to signal reward and of detecting subject peck responses. In Experiment 1, subjects were instrumentally shaped to peck at a single ARENA module following an unsuccessful autoshaping procedure. In Experiment 2, pigeons were trained with a simultaneous discrimination procedure during which two modules were illuminated different colors; pecks to one color (S+) were reinforced while pecks to the other color (S−) were not. Pigeons learned to preferentially peck the module displaying the S+. In Experiment 3, two modules were lit the same color concurrently from a set of six colors in a conditional discrimination task. For three of the colors pecks to the module in one location (e.g., upper quadrant) were reinforced while for the remaining colors pecks at the other module (e.g., lower quadrant) were reinforced. After learning this discrimination, the color-reinforced location assignments were reversed. Pigeons successfully acquired the reversal. ARENA is an automated system for open-field studies and a more ecologically valid alternative to the touchscreen. PMID:19429204

  11. Differences between appetitive and aversive reinforcement on reorientation in a spatial working memory task.

    Tasks using appetitive reinforcers show that following disorientation rats use the shape of an arena to reorient, and cannot distinguish two geometrically similar corners to obtain a reward, despite the presence of a prominent visual cue that provides information to differentiate the two corners. Other studies show that disorientation impairs performance on certain appetitive, but not aversive, tasks. This study evaluated whether rats would make similar geometric errors in a working memory task that used aversive reinforcement. We hypothesized that in a task that used aversive reinforcement rats that were initially disoriented would not reorient by arena shape and thus make similar geometric errors. Tests were performed in a rectangular arena having one polarizing cue. In the appetitive condition water consumption was the reward. The aversive condition was a water maze task with reinforcement provided by escape to a hidden platform. In the aversive condition rats returned to the reinforced corner significantly more often than in the dry condition, and did not favor the diagonally opposite corner. Results show that rats can use cues besides arena shape to reorient in an aversive reinforcement condition. These findings may also reflect different strategies, with an escape/homing strategy in the wet condition and a foraging strategy in the dry condition.

    A special set-up for continuous measurements of radon exhalation rate from soil is presented. It was constructed at Laboratory of Radiometric Expertise, Institute of Nuclear Physics Polish Academy of Sciences (IFJ PAN), Krakow, Poland. Radon exhalation rate was determined using the AlphaGUARD PQ2000 PRO (Genitron) radon monitor together with a special accumulation container which was put on the soil surface during the measurement. A special automatic device was built and used to raise and lower back onto the ground the accumulation container. The time of raising and putting down the container was controlled by an electronic timer. This set-up mademore » it possible to perform 4–6 automatic measurements a day. Besides, some additional soil and meteorological parameters were continuously monitored. In this way, the diurnal and seasonal variability of radon exhalation rate from soil can be studied as well as its dependence on soil properties and meteorological conditions.« less

    Malignant tumors of the upper aerodigestive tract may be rare by their histology (sarcoma, variants of conventional squamous cell carcinomas) and/or location (sinuses, salivary glands, ear, of various histologies themselves). They represent less than 10% of head and neck neoplasms. The confirmation of their diagnosis often requires a medical expertise and sometimes biomolecular techniques complementary to classical histology and immunohistochemistry. Due to their location, their treatment often requires a specific surgical technique. Radiation therapy is indicated based on histoclinical characteristics common to other head and neck neoplasms but also incorporate grade. Further, the technique must often be adapted to take into account the proximity of organs at risk. For most histologies, chemotherapy is relatively inefficient but current molecular advances may allow to consider pharmaceutical developments in the coming years. The REFCOR, the French Network of head and neck cancers aims to organize and promote the optimal management of these rare and heterogeneous diseases, to promote research and clinical trials.

    2016-09-01

    There is growing demand for robust evidence to address complex social phenomena such as violence against women and girls (VAWG). Research partnerships between scientists and non-governmental or international organizations (NGO/IO) are increasingly popular, but can pose challenges, including concerns about potential conflicts of interest. Drawing on our experience collaborating on VAWG research, we describe challenges and contributions that NGO/IO and academic partners can make at different stages of the research process and the effects that collaborations can have on scientific inquiry. Partners may struggle with differing priorities and misunderstandings about roles, limitations, and intentions. Benefits of partnerships include a shared vision of study goals, differing and complementary expertise, mutual respect, and a history of constructive collaboration. Our experience suggests that when investigating multi-faceted social problems, instead of 'rigging' study results, research collaborations can strengthen scientific rigor and offer the greatest potential for impact in the communities we seek to serve.

    2011-03-16

    Are experts born with particular predispositions, or are they made through experience? We examined brain structure in expert phoneticians, individuals who are highly trained to analyze and transcribe speech. We found a positive correlation between the size of left pars opercularis and years of phonetic transcription training experience, illustrating how learning may affect brain structure. Phoneticians were also more likely to have multiple or split left transverse gyri in the auditory cortex than nonexpert controls, and the amount of phonetic transcription training did not predict auditory cortex morphology. The transverse gyri are thought to be established in utero; our results thus suggest that this gross morphological difference may have existed before the onset of phonetic training, and that its presence confers an advantage of sufficient magnitude to affect career choices. These results suggest complementary influences of domain-specific predispositions and experience-dependent brain malleability, influences that likely interact in determining not only how experience shapes the human brain but also why some individuals become engaged by certain fields of expertise.

  16. Complementary and alternative medicine. Integrative medicine: business risks and opportunities.

    1998-01-01

    Much of the buzz over integrative medicine is well deserved. The opportunities seem to outweigh the risks, but superior management skills are needed to guide these programs through adolescence into clinical and business maturity. By carefully considering the staffing, team building, compensation methods, marketing, and program evaluation and development issues explored in this article, health care and physician executives should be able to steer between the rocks on their way to integrative medicine decisions that are right for their organizations. Many claim that integrative medicine has the potential to reshape health care delivery in a more patient-centered direction. While this may be true, such programs must prove themselves from financial and clinical operational perspectives in order to achieve this potential. Luminary clinical skills are not enough to guarantee the survival of such programs--a strong clinical base of expertise in alternative therapies is a key success factor. As with any health care venture, there are no substitutes for clinical excellence or sound management.

    2013-04-01

    Previous studies have reported a hemispheric asymmetry in processing dominant (e.g., paper) and subordinate (e.g., farmer) associations of ambiguous words (pen). Here we applied sham and anodal Transcranial Direct Current Stimulation (tDCS) over Wernicke's area and its right homologue to test whether we can modulate the selective hemispheric expertise in processing lexical ambiguity. Ambiguous prime words were presented followed by target words that could be associated to the dominant or subordinate meaning of the prime in a semantic relatedness task. Anodal stimulation of the right Wernicke's area significantly decreased response time (RTs) to subordinate but not dominant associations compared to sham stimulation. There was also a complementary trend of faster responses to dominant associations following anodal stimulation of Wernicke's area. The results support brain asymmetry in processing lexical ambiguity and show that tDCS can enhance complex language processing even in a sample of highly literate individuals.

    The World Health Organization (WHO) serves as a key organization to bring together experts along the continuum of vaccine development and regulatory approval, among its other functions. Using the revision of WHO's guidelines on prophylactic human papillomavirus (HPV) vaccine as an example, we describe the process by which (1) a need to revise the guidelines was identified; (2) a group of stakeholders with complementary expertise and key questions were identified; (3) a scientific review was conducted; (4) consensus on revisions was achieved; (5) guidelines were updated, reviewed widely, and approved. This multi-year process resulted in the consensus that regulatory agencies could consider additional endpoints, such as persistent HPV infection or immune equivalence, depending on the design of the HPV vaccine trials. Updating the guidelines will now accelerate vaccine development, reduce costs of clinical trials, and lead to faster regulatory approval. Copyright © 2016. Published by Elsevier B.V.

  1. One Health: parasites and beyond.

    PubMed

    Blake, Damer P; Betson, Martha

    2017-01-01

    The field of parasitism is broad, encompassing relationships between organisms where one benefits at the expense of another. Traditionally the discipline focuses on eukaryotes, with the study of bacteria and viruses complementary but distinct. Nonetheless, parasites vary in size and complexity from single celled protozoa, to enormous plants like those in the genus Rafflesia. Lifecycles range from obligate intracellular to extensive exoparasitism. Examples of parasites include high-profile medical and zoonotic pathogens such as Plasmodium, veterinary pathogens of wild and captive animals and many of the agents which cause neglected tropical diseases, stretching to parasites which infect plants and other parasites (e.g. Kikuchi et al. 2011; Hotez et al. 2014; Blake et al. 2015; Hemingway, 2015; Meekums et al. 2015; Sandlund et al. 2015). The breadth of parasitology has been matched by the variety of ways in which parasites are studied, drawing upon biological, chemical, molecular, epidemiological and other expertise. Despite such breadth bridging between disciplines has commonly been problematic, regardless of extensive encouragement from government agencies, peer audiences and funding bodies promoting multidisciplinary research. Now, progress in understanding and collaboration can benefit from establishment of the One Health concept (Zinsstag et al. 2012; Stark et al. 2015). One Health draws upon biological, environmental, medical, veterinary and social science disciplines in order to improve human, animal and environmental health, although it remains tantalizingly difficult to engage many relevant parties. For infectious diseases traditional divides have been exacerbated as the importance of wildlife reservoirs, climate change, food production systems and socio-economic diversity have been recognized but often not addressed in a multidisciplinary manner. In response the 2015 Autumn Symposium organized by the British Society for Parasitology (BSP; https://www.bsp.uk.net/home/) was focused on One Health, running under the title 'One Health: parasites and beyond…'. The meeting, held at the Royal Veterinary College (RVC) in Camden, London from September 14th to 15th, drew upon a blend of specialist parasitology reinforced with additional complementary expertise. Scientists, advocates, policy makers and industry representatives were invited to present at the meeting, promoting and developing One Health understanding with relevance to parasitology. The decision to widen the scope of the meeting to non-parasitological, but informative topics, is reflected in the diversity of the articles included in this special issue. A key feature of the meeting was encouragement of early career scientists, with more than 35% of the delegates registered as students and 25 posters.

  5. Acetylcholine contributes to the integration of self-movement cues in head direction cells.

    2017-08-01

    Acetylcholine contributes to accurate performance on some navigational tasks, but details of its contribution to the underlying brain signals are not fully understood. The medial septal area provides widespread cholinergic input to various brain regions, but selective damage to medial septal cholinergic neurons generally has little effect on landmark-based navigation, or the underlying neural representations of location and directional heading in visual environments. In contrast, the loss of medial septal cholinergic neurons disrupts navigation based on path integration, but no studies have tested whether these path integration deficits are associated with disrupted head direction (HD) cell activity. Therefore, we evaluated HD cell responses to visual cue rotations in a familiar arena, and during navigation between familiar and novel arenas, after muscarinic receptor blockade with systemic atropine. Atropine treatment reduced the peak firing rate of HD cells, but failed to significantly affect other HD cell firing properties. Atropine also failed to significantly disrupt the dominant landmark control of the HD signal, even though we used a procedure that challenged this landmark control. In contrast, atropine disrupted HD cell stability during navigation between familiar and novel arenas, where path integration normally maintains a consistent HD cell signal across arenas. These results suggest that acetylcholine contributes to path integration, in part, by facilitating the use of idiothetic cues to maintain a consistent representation of directional heading.

    To compare prey and snake paradigms performed in complex environments to the elevated plus-maze (EPM) and T-maze (ETM) tests for the study of panic attack- and anticipatory anxiety-like behaviors in rodents. PubMed was reviewed in search of articles focusing on the plus maze test, EPM, and ETM, as well as on defensive behaviors displayed by threatened rodents. In addition, the authors' research with polygonal arenas and complex labyrinth (designed by the first author for confrontation between snakes and small rodents) was examined. The EPM and ETM tests evoke anxiety/fear-related defensive responses that are pharmacologically validated, whereas the confrontation between rodents and snakes in polygonal arenas with or without shelters or in the complex labyrinth offers ethological conditions for studying more complex defensive behaviors and the effects of anxiolytic and panicolytic drugs. Prey vs. predator paradigms also allow discrimination between non-oriented and oriented escape behavior. Both EPM and ETM simple labyrinths are excellent apparatuses for the study of anxiety- and instinctive fear-related responses, respectively. The confrontation between rodents and snakes in polygonal arenas, however, offers a more ethological environment for addressing both unconditioned and conditioned fear-induced behaviors and the effects of anxiolytic and panicolytic drugs.

    This paper describes a series of experiments to examine the mode of action and toxicity of three plant essential oils (thyme, manuka and pennyroyal) to the poultry red mite, Dermanyssus gallinae (De Geer), a serious ectoparasitic pest of laying hens. All three oils were found to be toxic to D. gallinae in laboratory tests with LC(50), LC(90) and LC(99) values below 0.05, 0.20 and 0.30mg/cm(3), respectively, suggesting that these products may make for effective acaricides against this pest. Further experiments demonstrated that when mites were exposed to only the vapour phase of the essential oil without contact with the oil itself, mortality was consistently higher in closed arenas than in arenas open to the surrounding environment, or in control arenas. This suggests that all three essential oils were toxic to D. gallinae by fumigant action. In addition, in an experiment where mites were allowed contact with the essential oil in either open or closed arenas, mortality was always reduced in the open arenas where this was comparable to control mortality for thyme and pennyroyal essential oil treatments. This supports the findings of the previous experiment and also suggests that, with the possible exception of manuka, the selected essential oils were not toxic to D. gallinae on contact. Statistical comparisons were made between the toxicity of the selected essential oils to D. gallinae in the current work and in a previous study conducted in the same laboratory. The results demonstrated considerable variation in LC(50), LC(90) and LC(99) values. Since both the essential oils and the mites were obtained from identical sources in the two studies, it is hypothesized that this variation resulted from the use of different 'batches' of essential oil, which could have varied in chemistry and hence acaricidal activity.

    The Girls STEAM Ahead with NASA (GSAWN) initiative partners the NASA's Universe of Learning (UoL) resources with public libraries to provide NASA-themed activities for girls and their families. The program expands upon the legacy program, NASA Science4Girls and Their Families, in celebration of National Women's History Month. Program resources include hands-on activities for engaging girls, such as coding experiences and use of remote telescopes, complementary exhibits, and professional development for library partner staff. The science-institute-embedded partners in NASA's UoL are uniquely poised to foster collaboration between scientists with content expertise and educators with pedagogy expertise. The thematic topics related to NASA Astrophysics enable audiences to experience the full range of NASA scientific and technical disciplines and the different career skills each requires. For example, an activity may focus on understanding exoplanets, methods of their detection, and characteristics that can be determined remotely. The events focus on engaging underserved and underrepresented audiences in Science, Technology, Engineering, and Mathematics (STEM) via use of research-based best practices, collaborations with libraries, partnerships with local and national organizations (e.g. National Girls Collaborative Project or NGCP), and remote engagement of audiences. NASA's UoL collaborated with another NASA STEM Activation partner, NASA@ My Library, to announce GSAWN to their extensive STAR_Net network of libraries. This partnership between NASA SMD-funded Science learning and literacy teams has included NASA@ My Library hosting a professional development webinar featuring a GSAWN activity, a newsletter and blog post about the program, and plans for future exhibit development. This presentation will provide an overview of the program's progress to engage girls and their families through the development and dissemination of NASA-based science programming.

    Public health leaders increasingly recognize the importance of multi-sector partnerships and systems approaches to address obesity. Public-private partnerships (PPP), which are joint ventures between government agencies and private sector entities, may help facilitate this process, but need to be delivered through comprehensive, transparent frameworks to maximize potential benefits and minimize potential risks for all partners. The City University of New York (CUNY) School of Public Health and the Healthy Weight Commitment Foundation (HWCF) propose to engage in a unique academic-private-sector research partnership to evaluate the impact and effectiveness of the food and beverage industry's investment in obesity and hunger prevention and reduction through community-level healthful eating and active living programs. The CUNY-HWCF academic-private partnership protocol described here incorporates best practices from the literature on PPP into the partnership's design. The CUNY-HWCF partnership design demonstrates how established guidelines for partnership components will actively incorporate and promote the principles of successful PPPs identified in various research papers. These identified principles of successful PPP, including mutuality (a reciprocal relationship between entities), and equality among partners, recognition of partners' unique strengths and roles, alignment of resources and expertise toward a common cause, and coordination and delegation of responsibilities, will be embedded throughout the design of governance, management, funding, intellectual property and accountability structures. The CUNY-HWCF partnership responds to the call for increased multi-sector work in obesity prevention and control. This framework aims to promote transparency and the shared benefits of complementary expertise while minimizing shared risks and conflicts of interest. This framework serves as a template for future academic-private research partnerships.

  10. The relationship of science teachers' beliefs and practices

    The relationships between constructivist and Science-Technology-Society (STS) teaching practices and teachers beliefs are the focus of this dissertation. This study is founded on the premise that individual teacher's beliefs are strong indicators of their instructional choices and teaching habits. The basic research premise is: the more complete and complex the individuals' belief structure about constructivist and STS teaching, the more expert and consistent the teacher is in the complementary constructivist teaching practices. This triangulation study used quantitative and qualitative methods. Three instruments were used: the Science Classroom Observation Rubric and Teaching Practices Assessment Inventory, from the Expert Science Teacher Educational Evaluation Model (ESTEEM), and the Science Teacher Beliefs About the Learning Environment Rubric (developed by the author). The results yielded significant multiple regression analysis regarding the relationships between beliefs and practices in constructivist/STS science teaching not documented elsewhere. Statistically significant factors contributing to expertise included the value teachers placed on their students as individuals whose ideas and contributions to the class are important, teachers' commitment to work as partners with students in the learning environment, and the importance of context, i.e., instruction which is personally relevant and meaningful. No differences were found related to gender or total years of teaching experience. A cross-case methodology was used to explore data from open-ended interviews and for examination of teachers' written comments regarding their interactions with students in the learning environment. Expertise was also shown to be linked to teachers with a commitment to life-long learning and to years of participation/leadership by teachers in state and national reform movements. Qualitative data corroborated these findings, providing a rich and authentic background to the correlational results and analysis of key demographics. Most noteworthy were teachers' comments regarding partnerships with their students and the importance of instructional relevancy.

    The use of bibliometric measures in the evaluation of research has increased considerably based on expertise from the growing research field of evaluative citation analysis (ECA). However, mounting criticism of such metrics suggests that the professionalization of bibliometric expertise remains contested. This paper investigates why impact metrics, such as the journal impact factor and the h-index, proliferate even though their legitimacy as a means of professional research assessment is questioned. Our analysis is informed by two relevant sociological theories: Andrew Abbott’s theory of professions and Richard Whitley’s theory of scientific work. These complementary concepts are connected in order to demonstrate that ECA has failed so far to provide scientific authority for professional research assessment. This argument is based on an empirical investigation of the extent of reputational control in the relevant research area. Using three measures of reputational control that are computed from longitudinal inter-organizational networks in ECA (1972–2016), we show that peripheral and isolated actors contribute the same number of novel bibliometric indicators as central actors. In addition, the share of newcomers to the academic sector has remained high. These findings demonstrate that recent methodological debates in ECA have not been accompanied by the formation of an intellectual field in the sociological sense of a reputational organization. Therefore, we conclude that a growing gap exists between an academic sector with little capacity for collective action and increasing demand for routine performance assessment by research organizations and funding agencies. This gap has been filled by database providers. By selecting and distributing research metrics, these commercial providers have gained a powerful role in defining de-facto standards of research excellence without being challenged by expert authority.

  12. Why the United States has no national health insurance: stakeholder mobilization against the welfare state, 1945--1996.

    PubMed

    Quadagno, Jill

    2004-01-01

    The United States is the only western industrialized nation that fails to provide universal coverage and the only nation where health care for the majority of the population is financed by for-profit, minimally regulated private insurance companies. These arrangements leave one-sixth of the population uninsured at any given time, and they leave others at risk of losing insurance as a result of normal life course events. Political theorists of the welfare state usually attribute the failure of national health insurance in the United States to broader forces of American political development, but they ignore the distinctive character of the health care financing arrangements that do exist. Medical sociologists emphasize the way that physicians parlayed their professional expertise into legal, institutional, and economic power but not the way this power was asserted in the political arena. This paper proposes a theory of stakeholder mobilization as the primary obstacle to national health insurance. The evidence supports the argument that powerful stakeholder groups, first the American Medical Association, then organizations of insurance companies and employer groups, have been able to defeat every effort to enact national health insurance across an entire century because they had superior resources and an organizational structure that closely mirrored the federated arrangements of the American state. The exception occurred when the AFL-CIO, with its national leadership, state federations and union locals, mobilized on behalf of Medicare.

  13. Being around and knowing the players: networks of influence in health policy.

    PubMed

    Lewis, Jenny M

    2006-05-01

    The accumulation and use of power is crucial to the health policy process. This paper examines the power of the medical profession in the health policy arena, by analysing which actors are perceived as influential, and how influence is structured in health policy. It combines an analysis of policy networks and social networks, to examine positional and personal influence in health policy in the state of Victoria, Australia. In the sub-graph of the influence network examined here, those most widely regarded as influential are academics, medically qualified and male. Positional actors (the top politician, political advisor and bureaucrat in health and the top nursing official) form part of a core group within this network structure. A second central group consists of medical influentials working in academia, research institutes and health-related NGOs. In this network locale overall, medical academics appear to combine positional and personal influence, and play significant intermediary roles across the network. While many claim that the medical profession has lost power in health policy and politics, this analysis yields few signs that the power of medicine to shape the health policy process has been greatly diminished in Victoria. Medical expertise is a potent embedded resource connecting actors through ties of association, making it difficult for actors with other resources and different knowledge to be considered influential. The network concepts and analytical techniques used here provide a novel means for uncovering different types of influence in health policy.

    Rationale Stroke is a time-critical medical emergency requiring specialized treatment. Prehospital delay contributes significantly to delayed or missed treatment opportunities. In-ambulance telemedicine can bring stroke expertise to the prehospital arena and facilitate this complex diagnostic and therapeutic process. Aims This study evaluates the efficacy, safety, feasibility, reliability and cost-effectiveness of in-ambulance telemedicine for patients with suspicion of acute stroke. We hypothesize that this approach will reduce the delay to in-hospital treatment by streamlining the diagnostic process and that prehospital stroke care will be improved by expert stroke support via telemedicine during the ambulance transportation. Design PreSSUB II is an interventional, prospective, randomized, open-blinded, end-point, single-center trial comparing standard emergency care by the Paramedic Intervention Team of the Universitair Ziekenhuis Brussel (control) with standard emergency care complemented with in-ambulance teleconsultation service by stroke experts (PreSSUB). Study Outcomes The primary efficacy endpoint is the call-to-brain imaging time. Secondary endpoints for the efficacy analysis include the prevalence of medical events diagnosed and corrected during in-ambulance teleconsultation, the proportion of patients with ischemic stroke receiving recanalization therapy, the assessment of disability, functional status, quality of life and overall well-being. Mortality at 90 days after stroke is the primary safety endpoint. Secondary safety analysis will involve the registration of any adverse event. Other analyses include assessment of feasibility and reliability and a health economic evaluation. PMID:27847888

    Electrospinning of biopolymeric scaffolds is a new and effective approach for creating replacement tissues to repair defects and/or damaged tissues with direct clinical application. However, many hurdles and technical concerns regarding biological issues, such as cell retention and the ability to grow, still need to be overcome to gain full access to the clinical arena. Interaction with the host human tissues, immunogenicity, pathogen transmission as well as production costs, technical expertise, and good manufacturing and laboratory practice requirements call for careful consideration when aiming at the production of a material that is available off-the-shelf, to be used immediately in operative settings. The issue of sterilization is one of the most important steps for the clinical application of these scaffolds. Nevertheless, relatively few studies have been performed to systematically investigate how sterilization treatments may affect the properties of electrospun polymers for tissue engineering. This paper presents the results of a comparative study of different sterilization techniques applied to an electrospun poly-L-lactide scaffold: soaking in absolute ethanol, dry oven and autoclave treatments, UV irradiation, and hydrogen peroxide gas plasma treatment. Morphological and chemical characterization was coupled with microbiological sterility assay to validate the examined sterilization techniques in terms of effectiveness and modifications to the scaffold. The results of this study reveal that UV irradiation and hydrogen peroxide gas plasma are the most effective sterilization techniques, as they ensure sterility of the electrospun scaffolds without affecting their chemical and morphological features.

    We investigated behavioural activity and temporal distribution (patterning) of mouse exploration in different open field (OF) arenas. Mice of 129S1 (S1) strain were subjected in parallel to three different OF arenas (Experiment 1), two different OF arenas in two trials (Experiment 2) or two trials of the same OF test (Experiment 3). Overall, mice demonstrated a high degree of similarity in the temporal profile of novelty-induced horizontal and vertical exploration (regardless of the size, colour and shape of the OF), which remained stable in subsequent OF exposures. In Experiments 4 and 5, we tested F1 hybrid mice (BALB/c-S1; NMRI-S1), and Vitamin D receptor knockout mice (generated on S1 genetic background), again showing strikingly similar temporal patterns of their OF exploration, despite marked behavioural strain differences in anxiety and activity. These results suggest that mice are characterised by stability of temporal organization of their exploration in different OF novelty situations.

    2014-01-01

    As car expertise increases, so does interference between the visual processing of faces and that of cars; this suggests performance trade-offs across domains of real-world expertise. Such interference between expert domains has been previously revealed in a relatively complex design, interleaving 2-back part-judgment task with faces and cars (Gauthier et al., 2003). However, the basis of this interference is unclear. Experiment 1A replicated the finding of interference between faces and cars, as a function of car expertise. Experiments 1B and 2 investigated the mechanisms underlying this effect by (1) providing baseline measures of performance and (2) assessing the specificity of this interference effect. Our findings support the presence of expertise-dependent interference between face and non-face domains of expertise. However, surprisingly, it is in the condition where faces are processed among cars with a disrupted configuration where expertise has a greater influence on faces. This finding highlights how expertise-related processing changes also occur for transformed objects of expertise and that such changes can also drive interference across domains of expertise.

    A large-arena bioassay is used to examine sex differences in spatiotemporal patterns of bed bug Cimex lectularius L. behavioural responses to either a human host or CO 2 gas. After release in the centre of the arena, 90% of newly-fed bed bugs move to hiding places in the corners within 24 h. They require 3 days to settle down completely in the arena, with generally low activity levels and the absence of responses to human stimuli for 5 days. After 8-9 days, persistent responses can be recorded. Sex differences are observed, in which females are more active during establishment, respond faster after feeding, expose themselves more than males during the daytime, and respond more strongly to the host signal. The number of bed bugs that rest in harbourages is found to vary significantly according to light setting and sex. Both sexes stay inside harbourages more in daylight compared with night, and males hide more than females during the daytime but not during the night. The spatial distribution of the bed bugs is also found to change with the presence of CO 2 , and peak aggregation around the odour source is observed after 24 min. Both male and female bed bugs move from hiding places or the border of the arena toward the centre where CO 2 is released. Peak responses are always highest during the night. Bed bug behaviour and behaviour-regulating features are discussed in the context of control methods.

    This article describes an EMS-controlled HVAC system that meets the ventilation and cooling needs of an 18,000-seat indoor ice hockey arena. The Buffalo Memorial Auditorium (affectionately referred to as the Aud) was built in 1937 under the Works Project Administration of the federal government. Its original configuration included a 12,000-seat arena with an ice skating rink. By the late 1980s, the city was unsuccessfully attempting to attract events and tenants to the auditorium, which lacked air conditioning and other modern amenities. Thus, it was decided to renovate the facility to make it marketable. The first phase of the renovation includedmore » installing an air-conditioning system in the arena and repairing the existing building systems that were inoperable because of deferred maintenance. After considering the existing conditions (such as size of the space, intermittent usage, construction restrictions, operating budgets and the limited operations staff), the engineering team designed an innovative HVAC system. The system's features include: a carbon dioxide monitoring device that controls the intake of outside air; an ice storage system that provides chilled water and shifts electrical demand to off-peak hours; and a design that uses the building mass as a heat sink. A new energy management system (EMS) determines building cooling needs based on the type of event, ambient conditions and projected audience size. Then, it selects the most economical method to obtain the desired arena temperature.« less

  8. Walking behavior in a circular arena modified by pulsed light stimulation in Drosophila melanogaster w1118 line.

    2018-05-01

    The Drosophila melanogaster white-eyed w 1118 line serves as a parental stock, allowing genetic recombination of any gene of interest along with a readily recognizable marker. w 1118 flies display behavioral susceptibility to environmental stimulation such as light. It is of great importance to characterize the behavioral performance of w 1118 flies because this would provide a baseline from which the effect of the gene of interest could be differentiated. Little work has been performed to characterize the walking behavior in adult w 1118 flies. Here we show that pulsed light stimulation increased the regularity of walking trajectories of w 1118 flies in circular arenas. We statistically modeled the distribution of distances to center and extracted the walking structures of w 1118 flies. Pulsed light stimulation redistributed the time proportions for individual walking structures. Specifically, pulsed light stimulation reduced the episodes of crossing over the central region of the arena. An addition of four genomic copies of mini-white, a common marker gene for eye color, mimicked the effect of pulsed light stimulation in reducing crossing in a circular arena. The reducing effect of mini-white was copy-number-dependent. These findings highlight the rhythmic light stimulation-evoked modifications of walking behavior in w 1118 flies and an unexpected behavioral consequence of mini-white in transgenic flies carrying w 1118 isogenic background.

  9. Gap between science and media revisited: Scientists as public communicators

    PubMed Central

    Peters, Hans Peter

    2013-01-01

    The present article presents an up-to-date account of the current media relations of scientists, based on a comprehensive analysis of relevant surveys. The evidence suggests that most scientists consider visibility in the media important and responding to journalists a professional duty—an attitude that is reinforced by universities and other science organizations. Scientific communities continue to regulate media contacts with their members by certain norms that compete with the motivating and regulating influences of public information departments. Most scientists assume a two-arena model with a gap between the arenas of internal scientific and public communication. They want to meet the public in the public arena, not in the arena of internal scientific communication. Despite obvious changes in science and in the media system, the orientations of scientists toward the media, as well as the patterns of interaction with journalists, have their roots in the early 1980s. Although there is more influence on public communication from the science organizations and more emphasis on strategic considerations today, the available data do not indicate abrupt changes in communication practices or in the relevant beliefs and attitudes of scientists in the past 30 y. Changes in the science–media interface may be expected from the ongoing structural transformation of the public communication system. However, as yet, there is little evidence of an erosion of the dominant orientation toward the public and public communication within the younger generation of scientists. PMID:23940312

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

    PubMed Central

    2014-01-01

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

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

  12. Gap between science and media revisited: scientists as public communicators.

    PubMed

    Peters, Hans Peter

    2013-08-20

    The present article presents an up-to-date account of the current media relations of scientists, based on a comprehensive analysis of relevant surveys. The evidence suggests that most scientists consider visibility in the media important and responding to journalists a professional duty--an attitude that is reinforced by universities and other science organizations. Scientific communities continue to regulate media contacts with their members by certain norms that compete with the motivating and regulating influences of public information departments. Most scientists assume a two-arena model with a gap between the arenas of internal scientific and public communication. They want to meet the public in the public arena, not in the arena of internal scientific communication. Despite obvious changes in science and in the media system, the orientations of scientists toward the media, as well as the patterns of interaction with journalists, have their roots in the early 1980s. Although there is more influence on public communication from the science organizations and more emphasis on strategic considerations today, the available data do not indicate abrupt changes in communication practices or in the relevant beliefs and attitudes of scientists in the past 30 y. Changes in the science-media interface may be expected from the ongoing structural transformation of the public communication system. However, as yet, there is little evidence of an erosion of the dominant orientation toward the public and public communication within the younger generation of scientists.

    The purpose of this study was to evaluate the performance of X-ray dark-field imaging for detection of retained foreign bodies in ex-vivo hands and feet. X-ray dark-field imaging, acquired with a three-grating Talbot-Lau interferometer, has proven to provide access to sub-resolution structures due to small-angle scattering. The study was institutional review board (IRB) approved. Foreign body parts included pieces of wood and metal which were placed in a formalin fixated human ex-vivo hand. The samples were imaged with a grating-based interferometer consisting of a standard microfocus X-ray tube (60 kVp, 100 W) and a Varian 2520-DX detector (pixel size: 127 μm). The attenuation and the dark-field signals provide complementary diagnostic information for this clinical task. With regard to detecting of wooden objects, which are clinically the most relevant, only the dark-field image revealed the locations. The signal is especially strong for dry wood which in comparison is poorly to non-visible in computed tomography. The detection of high atomic-number or dense material and wood-like or porous materials in a single X-ray scan is enabled by the simultaneous acquisition of the conventional attenuation and dark-field signal. Our results reveal that with this approach one can reach a significantly improved sensitivity for detection of foreign bodies, while an easy implementation into the clinical arena is becoming feasible.

  14. Utility of spatially-resolved atmospheric pressure surface sampling and ionization techniques as alternatives to mass spectrometric imaging (MSI) in drug metabolism.

    Tissue distribution studies of drug molecules play an essential role in the pharmaceutical industry and are commonly undertaken using quantitative whole body autoradiography (QWBA) methods. The growing need for complementary methods to address some scientific gaps around radiography methods has led to increased use of mass spectrometric imaging (MSI) technology over the last 5 to 10 years. More recently, the development of novel mass spectrometric techniques for ambient surface sampling has redefined what can be regarded as "fit-for-purpose" for MSI in a drug metabolism and disposition arena. Together with a review of these novel alternatives, this paper details the use of two liquid microjunction (LMJ)-based mass spectrometric surface sampling technologies. These approaches are used to provide qualitative determination of parent drug in rat liver tissue slices using liquid extraction surface analysis (LESA) and to assess the performance of a LMJ surface sampling probe (LMJ-SSP) interface for quantitative assessment of parent drug in brain, liver and muscle tissue slices. An assessment of the utility of these spatially-resolved sampling methods is given, showing interdependence between mass spectrometric and QWBA methods, in particular there emerges a reason to question typical MSI workflows for drug metabolism; suggesting the expedient use of profile or region analysis may be more appropriate, rather than generating time-intensive molecular images of the entire tissue section.

    To give an overview of important methodological challenges in collecting, validating, and further processing experiential expertise and how to address these challenges. Based on our own experiences in studying the concept, operationalization, and contents of experiential expertise, we have formulated methodological issues regarding the inventory and application of experiential expertise. The methodological challenges can be categorized in six developmental research stages, comprising the conceptualization of experiential expertise, methods to harvest experiential expertise, the validation of experiential expertise, evaluation of the effectiveness, how to translate experiential expertise into acceptable guidelines, and how to implement these. The description of methodological challenges and ways to handle those are illustrated using diabetes mellitus as an example. Experiential expertise can be defined and operationalized in terms of successful illness-related behaviors and translated into recommendations regarding life domains. Pathways have been identified to bridge the gaps between the world of patients' daily lives and the medical world. Copyright © 2016 Elsevier Inc. All rights reserved.

  16. Expertise, Ethics Expertise, and Clinical Ethics Consultation: Achieving Terminological Clarity

    2016-01-01

    The language of ethics expertise has become particularly important in bioethics in light of efforts to establish the value of the clinical ethics consultation (CEC), to specify who is qualified to function as a clinical ethics consultant, and to characterize how one should evaluate whether or not a person is so qualified. Supporters and skeptics about the possibility of ethics expertise use the language of ethics expertise in ways that reflect competing views about what ethics expertise entails. We argue for clarity in understanding the nature of expertise and ethics expertise. To be an ethics expert, we argue, is to be an expert in knowing what ought to be done. Any attempt to articulate expertise with respect to knowing what ought to be done must include an account of ethics that specifies the nature of moral truth and the means by which we access this truth or a theoretical account of ethics such that expertise in another domain is linked to knowing or being better at judging what ought to be done and the standards by which this “knowing” or “being better at judging” is determined. We conclude with a discussion of the implications of our analysis for the literature on ethics expertise in CEC. We do think that there are clear domains in which a clinical ethics consultant might be expert but we are skeptical about the possibility that this includes ethics expertise. Clinical ethics consultants should not be referred to as ethics experts. PMID:27256848

  17. SUPPORT OF GULF OF MEXICO HYDRATE RESEARCH CONSORTIUM: ACTIVITIES TO SUPPORT ESTABLISHMENT OF A SEA FLOOR MONITORING STATION PROJECT

    Paul Higley; J. Robert Woolsey; Ralph Goodman

    The Gulf of Mexico Hydrates Research Consortium (GOM-HRC) was established in 1999 to assemble leaders in gas hydrates research. The primary objective of the group has been to design and emplace a remote monitoring station or sea floor observatory (MS/SFO) on the sea floor in the northern Gulf of Mexico by the year 2005, in an area where gas hydrates are known to be present at, or just below, the sea floor. This mission, although unavoidably delayed by hurricanes and other disturbances, necessitates assembling a station that will monitor physical and chemical parameters of the sea water and sea floormore » sediments on a more-or-less continuous basis over an extended period of time. Development of the station has always included the possibility of expanding its capabilities to include biological monitoring, as a means of assessing environmental health. This possibility has recently achieved reality via the National Institute for Undersea Science and Technology's (NIUST) solicitation for proposals for research to be conducted at the MS/SFO. Establishment of the Consortium has succeeded in fulfilling the critical need to coordinate activities, avoid redundancies and communicate effectively among researchers in the arena of gas hydrates research. Complementary expertise, both scientific and technical, has been assembled to promote innovative research methods and construct necessary instrumentation. The observatory has achieved a microbial dimension in addition to the geophysical and geochemical components it had already included. Initial components of the observatory, a probe that collects pore-fluid samples and another that records sea floor temperatures, were deployed in Mississippi Canyon 118 in May of 2005. Follow-up deployments, planned for fall 2005, have had to be postponed and the use of the vessel M/V Ocean Quest and its two manned submersibles sacrificed due to the catastrophic effects of Hurricane Katrina (and later, Rita) on the Gulf Coast. Every effort is being made to locate and retain the services of a replacement vessel and submersibles or Remotely Operated Vehicles (ROVs) but these efforts have been fruitless due to the demand for these resources in the tremendous recovery effort being made in the Gulf area. Station/observatory completion, anticipated for 2007, will likely be delayed by at least one year. The seafloor monitoring station/observatory is funded approximately equally by three federal Agencies: Minerals Management Services (MMS) of the Department of the Interior (DOI), National Energy Technology Laboratory (NETL) of the Department of Energy (DOE), and the National Institute for Undersea Science and Technology (NIUST), an agency of the National Oceanographic and Atmospheric Administration (NOAA). Subcontractors with FY03 funding fulfilled their technical reporting requirements in the previous report (41628R10). Only unresolved matching funds issues remain and will be addressed in the report of the University of Mississippi's Office of Research and Sponsored Programs.« less

  18. ``Political'' Science

    NASA Astrophysics Data System (ADS)

    Berzak Hopkins, Laura

    2013-03-01

    Politics and policy affect all of us, both as scientists and as citizens, and issues ranging from laboratory budgets to arms control treaties clearly require research problem-solving skills and technical expertise. There is a critical role for scientists in each aspect of the political system, and in fact, we as a society need more scientists to take part in politics. Furthermore, the research we pursue has important societal applications and is fascinating! We have a right and a responsibility to share our scientific knowledge not only with each other, but with the general public as well. So, why are we as a community of scientists reticent in the public arena, hesitant to enter politics, and even at times unsupportive of our peers who transition into governmental roles? In this time of fiscal constraint, when difficult research funding (and de-funding) choices are regularly being made, we as scientists must step up to the plate, reach across the aisle, and explain why what we do is fascinating, inspiring, and important, not just to us, but to society as a whole. A range of policy-relevant roles exists inside and outside the laboratory, such as Congressional Fellowships. Each year the Congressional Fellowships program brings together approximately thirty scientists at all stages of their careers to serve as scientific advisors in a variety of offices in the U.S. Senate and House of Representatives. Although the jump from lab to lobbying meetings can be frustrating, the transition can also be intriguing. Firsthand experience with the ``how'' and ``why'' (or lack thereof) of politics and policy is invaluable and provides a unique opportunity to expand and broaden one's background. The opportunity to work on Capitol Hill is unparalleled, particularly because our nation has a definite need for scientists with the inclination and interest to inform and develop policy. But, whatever role you decide to take, from contributing scientific news to local publications to running for Congress, it's high time to show that we as scientists have important contributions to make both inside and outside the laboratory. We as scientists can and should contribute to ongoing political discussions, and there is no better time than now to speak up and apply our expertise to the policy issues at hand.

    Significant insights into visual cognition have come from studying real-world perceptual expertise. Many have previously reviewed empirical findings and theoretical developments from this work. Here we instead provide a brief perspective on approaches, considerations, and challenges to studying real-world perceptual expertise. We discuss factors like choosing to use real-world versus artificial object domains of expertise, selecting a target domain of real-world perceptual expertise, recruiting experts, evaluating their level of expertise, and experimentally testing experts in the lab and online. Throughout our perspective, we highlight expert birding (also called birdwatching) as an example, as it has been used as a target domain for over two decades in the perceptual expertise literature.

  20. Moral Expertise in the Clinic: Lessons Learned from Medicine and Science

    McClimans, Leah; Slowther, Anne

    2016-01-01

    Philosophers and others have questioned whether or not expertise in morality is possible. This debate is not only theoretical, but also affects the perceived legitimacy of clinical ethicists. One argument against moral expertise is that in a pluralistic society with competing moral theories no one can claim expertise regarding what another ought morally to do. There are simply too many reasonable moral values and intuitions that affect theory choice and its application; expertise is epistemically uniform. In this article, we discuss how similar concerns have recently threatened to undermine expertise in medicine and science. In contrast, we argue that the application of values is needed to exercise medical, scientific, and moral expertise. As long as these values are made explicit, worries about a pretense to authority in the context of a liberal democracy are ill-conceived. In conclusion, we argue for an expertise that is epistemically diverse. PMID:27302969

    Although high rates of traditional medicine and complementary and alternative medicine (TM/CAM) use have been well documented, there has been less attention to the factors influencing communication between patients and their primary care clinicians about TM/CAM. Such communication can be important in anticipating possible drug-herb interactions and in assuring agreement about therapeutic plans. We used sequential, multistage, qualitative methods, including focus groups, in-depth interviews, and a video vignette, to explore communication about TM/CAM between patients and their primary care clinicians. The study was conducted in RIOS Net (Research Involved in Outpatient Settings Network), a Southwestern US practice-based research network, situated largely in Hispanic and American Indian communities where TM/CAM is an important part of self-care. One hundred fourteen patients, 41 clinic staff members, and 19 primary care clinicians in 8 clinic sites participated. The degree and nature of TM/ CAM communication is based on certain conditions in the clinical encounter. We categorized these findings into 3 themes: acceptance/nonjudgment, initiation of communication, and safety/efficacy. Perceived clinician receptivity to and initiation of discussion about TM/CAM strongly influenced patients' decisions to communicate; perceived clinician expertise in TM/CAM was less important. Clinicians' comfort with patients' self-care approaches and their level of concern about lack of scientific evidence of effectiveness and safety of TM/CAM influenced their communication about TM/CAM with patients. Specific communication barriers limit patient-clinician communication about TM/CAM. Clinicians who wish to communicate more effectively with their patients about these topics and better integrate the types of care their patients use can change the communication dynamic with simple strategies designed to overcome these barriers.

    The rise in complementary and alternative medicine (CAM) use is well documented. Surveys provide varying estimates of the prevalence of CAM use. Qualitative research has explored individuals' decision-making regarding CAM. This study aimed to examine the family as a context for beliefs, decision-making, and dialogue about CAM. Families were recruited via the Avon Longitudinal Study of Parents and Children. A subsample of CAM users was targeted using purposeful sampling. Focus groups and interviews were conducted with 15 families and the data were analyzed thematically. Family understandings and beliefs about CAM: CAM was understood as treatments provided outside mainstream care, offering a more "natural" and "holistic" approach, tailored to individual needs and overlapping with wider healthy lifestyle practices. Hierarchies of acceptability of CAM: Physical and "mainstream" therapies were widely supported, with "fringe" therapies producing the most polarized views. There was a belief particularly among fathers and young people that certain therapies rely on "placebo" effects and their value was contested. Types of CAM users within families: Family members were predominantly "pragmatic" CAM users, with "committed" users (all mothers) characterized by deeper philosophical commitment to CAM and skepticism toward conventional medicine. Family dynamics of CAM decision-making: Mothers tended to "champion" CAM within families, while not determining family CAM use. Fathers largely positioned themselves as lacking expertise or skeptical of CAM. Young people were beginning to articulate independent and more critical views of CAM, some directly challenging their mother's perspective. However, all families shared openness to CAM as part of broader beliefs in proactive healthy lifestyles. Family focus groups and interviews allow a window on beliefs, decision-making, and dialogue about CAM within families, illuminating the CAM "champion" role held by mothers, and young people's developing autonomy regarding health beliefs and decision-making.

    2015-01-01

    The fusiform face area (FFA) is one of several areas in occipito-temporal cortex whose activity is correlated with perceptual expertise for objects. Here, we investigate the robustness of expertise effects in FFA and other areas to a strong task manipulation that increases both perceptual and attentional demands. With high-resolution fMRI at 7Telsa, we measured responses to images of cars, faces and a category globally visually similar to cars (sofas) in 26 subjects who varied in expertise with cars, in (a) a low load 1-back task with a single object category and (b) a high load task in which objects from two categories rapidly alternated and attention was required to both categories. The low load condition revealed several areas more active as a function of expertise, including both posterior and anterior portions of FFA bilaterally (FFA1/FFA2 respectively). Under high load, fewer areas were positively correlated with expertise and several areas were even negatively correlated, but the expertise effect in face-selective voxels in the anterior portion of FFA (FFA2) remained robust. Finally, we found that behavioral car expertise also predicted increased responses to sofa images but no behavioral advantages in sofa discrimination, suggesting that global shape similarity to a category of expertise is enough to elicit a response in FFA and other areas sensitive to experience, even when the category itself is not of special interest. The robustness of expertise effects in right FFA2 and the expertise effects driven by visual similarity both argue against attention being the sole determinant of expertise effects in extrastriate areas.

    Printed educational materials (PEMs) have long demonstrated their usefulness as economical and effective media for health communication. In this article, we evaluate the impact of targeted tobacco cessation PEMS for use along with a brief intervention training designed for three types of complementary and alternative medicine (CAM) practitioners: chiropractic, acupuncture, and massage. We describe how PEMs in CAM practitioners’ offices were perceived and used by practitioners and by patients. Semistructured qualitative interviews were conducted with 53 practitioners and 38 of their patients. This analysis specifically focused on developing and distributing project-related posters and pamphlets in CAM practice. Our findings indicate that materials (1) legitimated tobacco-related expertise among CAM practitioners and tobacco-related conversations as part of routine CAM practice, (2) increased practitioners’ willingness to approach the topic of tobacco with patients, (3) created an effective way to communicate tobacco-related information and broaden the reach of brief intervention initiatives, and (4) were given to patients who were not willing to engage in direct discussion of tobacco use with practitioners.

    Evaluating automated indexing applications requires comparing automatically indexed terms against manual reference standard annotations. However, there are no standard guidelines for determining which words from a textual document to include in manual annotations, and the vague task can result in substantial variation among manual indexers. We applied grounded theory to emergency department reports to create an annotation schema representing syntactic and semantic variables that could be annotated when indexing clinical conditions. We describe the annotation schema, which includes variables representing medical concepts (e.g., symptom, demographics), linguistic form (e.g., noun, adjective), and modifier types (e.g., anatomic location, severity). We measured the schema’s quality and found: (1) the schema was comprehensive enough to be applied to 20 unseen reports without changes to the schema; (2) agreement between author annotators applying the schema was high, with an F measure of 93%; and (3) an error analysis showed that the authors made complementary errors when applying the schema, demonstrating that the schema incorporates both linguistic and medical expertise.

    Innovation has been a central focus of the Department of Surgery at the Brigham and Women's Hospital since its very inception. Here we review examples of innovations originating in this Department and analyze factors that have been critical to successful innovation. Finally, we discuss challenges to sustainability of innovation in this Department. Narrative review of the literature, interviews, and personal observations. Examples of innovations reviewed here were each dependent on three critical elements: 1) multidisciplinary collaboration among surgical innovators and individuals outside of surgery who offered complementary skills and expertise, 2) a rich institutional environment that sustained a diverse complement of innovators working in close proximity, and 3) Department Chairmen who facilitated the work of innovators and promoted their contributions, rather than seeking personal prestige or financial gain. Contemporary challenges to sustainability of innovation include the prevailing emphasis on clinical efficiency and on cost containment. We have identified factors critical to successful innovation in a Department of Surgery. The relevance of these factors is unlikely to be diminished, even in the changing landscape of modern medicine.

    The modeling of ultrasonic Non Destructive Evaluation often plays an important part in the assessment of detection capabilities or as a help to interpret experiments. The ultrasonic modeling tool of the CIVA platform uses semi-analytical approximations for fast computations. Kirchhoff and GTD are two classical approximations for the modeling of echoes from plane-like defects such as cracks, and they aim at taking into account two different types of physical phenomena. The Kirchhoff approximation is mainly suitable to predict specular reflections from the flaw surface, whereas GTD is dedicated to the modeling of edge diffraction. As a consequence, these two approximationsmore » have distinct and complementary validity domains. Choosing between them requires expertise and is problematic in some inspection configurations. The Physical Theory of Diffraction (PTD) was developed based on both Kirchhoff and GTD in order to combine their advantages and overcome their limitations. The theoretical basis for PTD and its integration in the CIVA modeling approach are discussed in this communication. Several results that validate this newly developed model and illustrate its advantages are presented.« less

    The Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) formed in 1998 to support the coastal mapping and charting requirements of the USACE, NAVO, NOAA and USGS. This partnership fielded three generations of airborne lidar bathymeters, executed operational data collection programs within the U.S. and overseas, and advanced research and development in airborne lidar bathymetry and complementary technologies. JALBTCX executes a USACE Headquarters-funded National Coastal Mapping Program (NCMP). Initiated in 2004, the NCMP provides high-resolution, high-accuracy elevation and imagery data along the sandy shorelines of the U.S. on a recurring basis. NCMP mapping activities are coordinated with Federal mapping partners through the Interagency Working Group on Ocean and Coastal Mapping and the 3D Elevation Program. The NCMP, currently in it's third cycle, is performing operations along the East Coast in 2017, after having completed surveys along the Gulf Coast in 2016 and conducting emergency response operations in support of Hurricane Matthew. This presentation will provide an overview of JALBTCX, its history in furthering airborne lidar bathymetry technology to meet emerging mapping requirements, current NCMP operations and data products, and Federal mapping coordination activities.

    Alcohol intoxication and overserving of alcohol at sporting events are of great concern, given the relationships between alcohol consumption, public disturbances, and violence. During recent years this matter has been on the agenda for Swedish policymakers, authorities and key stakeholders, with demands that actions be taken. There is promising potential for utilizing an environmental approach to alcohol prevention as a strategy to reduce the level of alcohol intoxication among spectators at sporting events. Examples of prevention strategies may be community mobilization, Responsible Beverage Service training, policy work, and improved controls and sanctions. This paper describes the design of a quasi-experimental control group study to examine the effects of a multi-component community-based alcohol intervention at matches in the Swedish Premier Football League. A baseline assessment was conducted during 2015 and at least two follow-up assessments will be conducted in 2016 and 2017. The two largest cities in Sweden are included in the study, with Stockholm as the intervention area and Gothenburg as the control area. The setting is Licensed Premises (LP) inside and outside Swedish football arenas, in addition to arena entrances. Spectators are randomly selected and invited to participate in the study by providing a breath alcohol sample as a proxy for Blood Alcohol Concentration (BAC). Actors are hired and trained by an expert panel to act out a standardized scene of severe pseudo-intoxication. Four types of cross-sectional data are generated: (i) BAC levels among ≥ 4 200 spectators, frequency of alcohol service to pseudo-intoxicated patrons attempting to purchase alcohol at LP (ii) outside the arenas (≥200 attempts) and (iii) inside the arenas (≥ 200 attempts), and (iv) frequency of security staff interventions towards pseudo-intoxicated patrons attempting to enter the arenas (≥ 200 attempts). There is an urgent need nationally and internationally to reduce alcohol-related problems at sporting events, and it is essential to test prevention strategies to reduce intoxication levels among spectators. This project makes an important contribution not only to the research community, but also to enabling public health officials, decision-makers, authorities, the general public, and the sports community, to implement appropriate evidence-based strategies.

  11. Association and dissociation between detection and discrimination of objects of expertise: Evidence from visual search.

    Expertise in face recognition is characterized by high proficiency in distinguishing between individual faces. However, faces also enjoy an advantage at the early stage of basic-level detection, as demonstrated by efficient visual search for faces among nonface objects. In the present study, we asked (1) whether the face advantage in detection is a unique signature of face expertise, or whether it generalizes to other objects of expertise, and (2) whether expertise in face detection is intrinsically linked to expertise in face individuation. We compared how groups with varying degrees of object and face expertise (typical adults, developmental prosopagnosics [DP], and car experts) search for objects within and outside their domains of expertise (faces, cars, airplanes, and butterflies) among a variable set of object distractors. Across all three groups, search efficiency (indexed by reaction time slopes) was higher for faces and airplanes than for cars and butterflies. Notably, the search slope for car targets was considerably shallower in the car experts than in nonexperts. Although the mean face slope was slightly steeper among the DPs than in the other two groups, most of the DPs' search slopes were well within the normative range. This pattern of results suggests that expertise in object detection is indeed associated with expertise at the subordinate level, that it is not specific to faces, and that the two types of expertise are distinct facilities. We discuss the potential role of experience in bridging between low-level discriminative features and high-level naturalistic categories.

  12. Expertise Development With Different Types of Automation: A Function of Different Cognitive Abilities.

    PubMed

    Jipp, Meike

    2016-02-01

    I explored whether different cognitive abilities (information-processing ability, working-memory capacity) are needed for expertise development when different types of automation (information vs. decision automation) are employed. It is well documented that expertise development and the employment of automation lead to improved performance. Here, it is argued that a learner's ability to reason about an activity may be hindered by the employment of information automation. Additional feedback needs to be processed, thus increasing the load on working memory and decelerating expertise development. By contrast, the employment of decision automation may stimulate reasoning, increase the initial load on information-processing ability, and accelerate expertise development. Authors of past research have not investigated the interrelations between automation assistance, individual differences, and expertise development. Sixty-one naive learners controlled simulated air traffic with two types of automation: information automation and decision automation. Their performance was captured across 16 trials. Well-established tests were used to assess information-processing ability and working-memory capacity. As expected, learners' performance benefited from expertise development and decision automation. Furthermore, individual differences moderated the effect of the type of automation on expertise development: The employment of only information automation increased the load on working memory during later expertise development. The employment of decision automation initially increased the need to process information. These findings highlight the importance of considering individual differences and expertise development when investigating human-automation interaction. The results are relevant for selecting automation configurations for expertise development. © 2015, Human Factors and Ergonomics Society.

  13. The "Ethics" Expertise in Clinical Ethics Consultation.

    PubMed

    Iltis, Ana S; Rasmussen, Lisa M

    2016-08-01

    The nature, possibility, and implications of ethics expertise (or moral expertise) in general and of bioethics expertise in particular has been the focus of extensive debate for over thirty years. What is ethics expertise and what does it enable experts to do? Knowing what ethics expertise is can help answer another important question: What, if anything, makes a claim of expertise legitimate? In other words, how does someone earn the appellation "ethics expert?" There remains deep disagreement on whether ethics expertise is possible, and if so, what constitutes such expertise and what it entails and legitimates. Discussion of bioethics expertise has become particularly important given the growing presence of bioethicists in the clinical setting as well as efforts to professionalize bioethics through codes of ethics and certification (or quasi-certification) efforts. Unlike in the law or in engineering, where there may be a body of knowledge that professional organizations or others have articulated as important for education and training of experts, ethics expertise admits of no such body of knowledge or required experience. Nor is there an entity seen as having the authority to articulate the necessary scope of knowledge. Questions about whether there is such a body of knowledge for particular areas within bioethics have emerged and played a central role in professionalization efforts in recent years, especially in the area of clinical ethics. © The Author 2016.

  14. Outcomes in EMS-transported attendees from events at a large indoor arena.

    PubMed

    Chan, Shu B; Quinn, James E

    2003-01-01

    Many emergency departments (EDs) receive patients from concert or other mass gathering events. The study objective was to determine whether routine emergency medical services (EMS) transport to a hospital from an indoor arena facility is warranted. Retrospective review of transport medical records from an approximately 20,000-seat arena in a major metropolitan area from January 1, 1998, to June 30, 1999. Outcomes studied included inpatient admission rate, diagnoses, treatments, and length of ED stay. The authors reviewed 96 patients transported from 29 separate concert or professional wrestling events. The mean age was 23.2 years (SD, 10.4 yr). Only three patients (3.1%, 95% confidence interval [CI], 0.65%-8.9%) required inpatient admission. The mean length of stay in the ED was 158 minutes (95% CI, 132-185). Thirty-one percent of the patients had diagnoses of alcohol or drug use; trauma accounted for 33%; and medical reasons represented 35% of transports. Alcohol and/or drug cases stayed in the ED 207 minutes (mean), which was 59% longer than trauma cases (130 min) and 47% longer than the 141 minutes for medical cases (p = 0.007). Rock concerts had 45% alcohol/drug-related cases versus 22% for pop concerts and 0% for professional wrestling events (p = 0.001). Patients transported from indoor arena events rarely result in inpatient admissions. Alcohol- and drug-related problems were the primary diagnoses in 31% of these patients and required the most time in the ED. Rock concerts had more alcohol and drug cases than other events.

    The most common lethal accidents in General Aviation are caused by improperly executed landing approaches in which a pilot descends below the minimum safe altitude without proper visual references. To understand how expertise might reduce such erroneous decision-making, we examined relevant neural processes in pilots performing a simulated landing approach inside a functional MRI scanner. Pilots (aged 20-66) were asked to "fly" a series of simulated "cockpit view" instrument landing scenarios in an MRI scanner. The scenarios were either high risk (heavy fog-legally unsafe to land) or low risk (medium fog-legally safe to land). Pilots with one of two levels of expertise participated: Moderate Expertise (Instrument Flight Rules pilots, n = 8) or High Expertise (Certified Instrument Flight Instructors or Air-Transport Pilots, n = 12). High Expertise pilots were more accurate than Moderate Expertise pilots in making a "land" versus "do not land" decision (CFII: d' = 3.62 ± 2.52; IFR: d' = 0.98 ± 1.04; p<.01). Brain activity in bilateral caudate nucleus was examined for main effects of expertise during a "land" versus "do not land" decision with the no-decision control condition modeled as baseline. In making landing decisions, High Expertise pilots showed lower activation in the bilateral caudate nucleus (0.97 ± 0.80) compared to Moderate Expertise pilots (1.91 ± 1.16) (p<.05). These findings provide evidence for increased "neural efficiency" in High Expertise pilots relative to Moderate Expertise pilots. During an instrument approach the pilot is engaged in detailed examination of flight instruments while monitoring certain visual references for making landing decisions. The caudate nucleus regulates saccade eye control of gaze, the brain area where the "expertise" effect was observed. These data provide evidence that performing "real world" aviation tasks in an fMRI provide objective data regarding the relative expertise of pilots and brain regions involved in it.

    A significant growth of research in nanofluidics is achieved over the past decade, but the field is still facing considerable challenges toward the transition from the current physics-centered stage to the next application-oriented stage. Many of these challenges are associated with materials science, so the field of nanofluidics offers great opportunities for materials scientists to exploit. In addition, the use of unusual effects and ultrasmall confined spaces of well-defined nanofluidic environments would offer new mechanisms and technologies to manipulate nanoscale objects as well as to synthesize novel nanomaterials in the liquid phase. Therefore, nanofluidics will be a new arena for materials science. In the past few years, burgeoning progress has been made toward this trend, as overviewed in this article, including materials and methods for fabricating nanofluidic devices, nanofluidics with functionalized surfaces and functional material components, as well as nanofluidics for manipulating nanoscale materials and fabricating new nanomaterials. Many critical challenges as well as fantastic opportunities in this arena lie ahead. Some of those, which are of particular interest, are also discussed. © 2017 WILEY-VCH Verlag GmbH & Co.

    2018-02-15

    The debate over the origins of individual differences in expertise has raged for over a century in psychology. The "nature" view holds that expertise reflects "innate talent"-that is, genetically determined abilities. The "nurture" view counters that, if talent even exists, its effects on ultimate performance are negligible. While no scientist takes seriously a strict nature-only view of expertise, the nurture view has gained tremendous popularity over the past several decades. This environmentalist view holds that individual differences in expertise reflect training history, with no important contribution to ultimate performance by innate ability ("talent"). Here, we argue that, despite its popularity, this view is inadequate to account for the evidence concerning the origins of expertise that has accumulated since the view was first proposed. More generally, we argue that the nature versus nurture debate in research on expertise is over-or certainly should be, as it has been in other areas of psychological research for decades. We describe a multifactorial model for research on the nature and nurture of expertise, which we believe will provide a progressive direction for future research on expertise. © 2018 New York Academy of Sciences.

    Contemporary genomics research will impact the daily practice of biology teachers who want to teach up-to-date genetics in secondary education. This article reports on a research project aimed at enhancing biology teachers' expertise for teaching genetics situated in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of an educational approach based on situated learning. What expertise do biology teachers need for teaching genetics in the personal health context of genetic testing? This article describes the required expertise by exploring the educational practice. Nine experienced teachers were interviewed about the pedagogical content, moral and interpersonal expertise areas concerning how to teach genetics in the personal health context of genetic testing, and the lessons of five of them were observed. The findings showed that the required teacher expertise encompasses specific pedagogical content expertise, interpersonal expertise and a preference for teacher roles and teaching approaches for the moral aspects of teaching in this context. A need for further development of teaching and learning activities for (reflection on) moral reasoning came to the fore. Suggestions regarding how to apply this expertise into context-based genetics education are discussed.

    2018-06-01

    The safety of vaginal breech birth depends on the expertise of birth attendants, yet the meaning of "expertise" remains unclear and subjectively defined. The objective of this study was to define expertise and the roles experts may play in expanding access to this service. We performed an integrative analysis of two strands of data concerning expertise in physiological breech birth, including the following: survey data from a Delphi study involving 26 very experienced clinicians (mean experience = 135 breech births) and 2 service user representatives, and interviews from a grounded theory study of 14 clinicians more moderately experienced with physiological methods (5-30 upright breech births). Data were pooled and analyzed using constant comparative methods. Expertise is defined by its ongoing function, the generation of comparatively good outcomes, and confidence and competence among colleagues. Although clinical experience is important, expertise is developed and expressed in social clinical roles, which expand as experience grows: clinician, mentor, specialist, and expert. To develop expertise within a service, clinicians who have an interest in breech birth should be supported to perform these roles within specialist teams. Specialist breech teams may facilitate the development of expertise within maternity care settings. Evaluation of expertise based on enablement of women and colleagues, as well as outcomes, will potentially avoid the pitfalls of alienation produced by some forms of specialist authority. © 2017 Wiley Periodicals, Inc.

  3. The Automation-by-Expertise-by-Training Interaction.

    PubMed

    Strauch, Barry

    2017-03-01

    I introduce the automation-by-expertise-by-training interaction in automated systems and discuss its influence on operator performance. Transportation accidents that, across a 30-year interval demonstrated identical automation-related operator errors, suggest a need to reexamine traditional views of automation. I review accident investigation reports, regulator studies, and literature on human computer interaction, expertise, and training and discuss how failing to attend to the interaction of automation, expertise level, and training has enabled operators to commit identical automation-related errors. Automated systems continue to provide capabilities exceeding operators' need for effective system operation and provide interfaces that can hinder, rather than enhance, operator automation-related situation awareness. Because of limitations in time and resources, training programs do not provide operators the expertise needed to effectively operate these automated systems, requiring them to obtain the expertise ad hoc during system operations. As a result, many do not acquire necessary automation-related system expertise. Integrating automation with expected operator expertise levels, and within training programs that provide operators the necessary automation expertise, can reduce opportunities for automation-related operator errors. Research to address the automation-by-expertise-by-training interaction is needed. However, such research must meet challenges inherent to examining realistic sociotechnical system automation features with representative samples of operators, perhaps by using observational and ethnographic research. Research in this domain should improve the integration of design and training and, it is hoped, enhance operator performance.

  4. Video Game Telemetry as a Critical Tool in the Study of Complex Skill Learning

    2013-01-01

    Cognitive science has long shown interest in expertise, in part because prediction and control of expert development would have immense practical value. Most studies in this area investigate expertise by comparing experts with novices. The reliance on contrastive samples in studies of human expertise only yields deep insight into development where differences are important throughout skill acquisition. This reliance may be pernicious where the predictive importance of variables is not constant across levels of expertise. Before the development of sophisticated machine learning tools for data mining larger samples, and indeed, before such samples were available, it was difficult to test the implicit assumption of static variable importance in expertise development. To investigate if this reliance may have imposed critical restrictions on the understanding of complex skill development, we adopted an alternative method, the online acquisition of telemetry data from a common daily activity for many: video gaming. Using measures of cognitive-motor, attentional, and perceptual processing extracted from game data from 3360 Real-Time Strategy players at 7 different levels of expertise, we identified 12 variables relevant to expertise. We show that the static variable importance assumption is false - the predictive importance of these variables shifted as the levels of expertise increased - and, at least in our dataset, that a contrastive approach would have been misleading. The finding that variable importance is not static across levels of expertise suggests that large, diverse datasets of sustained cognitive-motor performance are crucial for an understanding of expertise in real-world contexts. We also identify plausible cognitive markers of expertise. PMID:24058656

    1993-08-01

    Although sexually receptive female hamsters prefer dominant males as mating partners, it is not clear what role the female might play facilitating aggressive interactions among males that would lead to the establishment of a status relationship. The ability of vaginal odors to stimulate male aggression was examined by paring randomly chosen males in a neutral arena with vaginal odors either present or absent. Males exhibited significantly more aggression when tested in the scented arena. Vaginal odors are efficient broadcast signals serving to space females, attract males, and to stimulate aggressive interactions among the males while inhibiting aggression towards the female.

The paper proposes to ground an explanation of the role of civil society in health care reforms in a Gramscian understanding of civil society as analytically different from the state, and as an arena for hegemonic struggles. The study of health care reform in Israel serves as a case study for this claim. Copyright © 2014 Elsevier Ltd. All rights reserved.

    When the principles of good laboratory practice (GLP) were drafted in 1982 by the Organisation for Economic Cooperation and Development (OECD) the electronic era was in its infant stages and many of the issues surrounding what may affect the environment and human health was not expected. Today, advances in technology for capturing and recording data for the reconstruction of a study are available and are being developed operating at speeds which could not have been known or understood in years past. Since that time, the United States Environmental Protection Agency (EPA) has required the conduct of additional studies in support of a pesticide registration in accordance with the GLP regulations. However, not all of these studies are required in other countries or may not require adherence to the principles of GLP. Companies are using computer models as virtual studies instead of inlife or bench type regulated research. Studies are often conducted at institutions of higher learning because of the academic expertise they offer. What is the overall impact advancing technology has on the principles of GLP? Are monitoring authorities (MAs) ready? The medical products field faces similar issues. Development and testing of these products and devices is being conducted similar to development and testing in the pesticide arena. To garner trust in mutual acceptance of data, each participating country must adhere to practices that ensure the highest standards of quality and integrity. The GLP inspector will need to have a good understanding of the science supporting the study conduct and the electronic systems that generate process and maintain study records.

    2015-05-01

    The explosion of technologic advances in information capture and delivery offers unparalleled opportunities to assess and modify built and social environments in ways that can positively impact health behaviors. This paper highlights some potentially transformative current and emerging trends in the technology arena applicable to environmental context-based assessment and intervention relevant to physical activity and dietary behaviors. A team of experts convened in 2013 to discuss the main issues related to technology use in assessing and changing built environments for health behaviors particularly relevant to obesity prevention. Each expert was assigned a specific domain to describe, commensurate with their research and expertise in the field, along with examples of specific applications. This activity was accompanied by selective examination of published literature to cover the main issues and elucidate relevant applications of technologic tools and innovations in this field. Decisions concerning which technology examples to highlight were reached through discussion and consensus-building among the team of experts. Two levels of impact are highlighted: the "me" domain, which primarily targets measurement and intervention activities aimed at individual-level behaviors and their surrounding environments; and the "we" domain, which generally focuses on aggregated data aimed at groups and larger population segments and locales. The paper ends with a set of challenges and opportunities for significantly advancing the field. Key areas for progress include data collection and expansion, managing technologic considerations, and working across sectors to maximize the population potential of behavioral health technologies.

  15. Psychodynamic Leadership Approach and Leader-Member Exchange (LMX): A Psychiatric Perspective on Two Leadership Theories and Implications for Training Future Psychiatrist Leaders.

    PubMed

    Plakiotis, Christos

    2017-01-01

    An increased emphasis in recent years on psychiatrists as healthcare leaders has not only drawn attention to the skills they can bring to this role but has also raised questions about how to best train and prepare them to assume leadership responsibilities. Such training should not be conducted in isolation from, and oblivious to, the wide-ranging expertise in human behaviour and relationships that psychiatrists can bring to the leadership arena. The aim of this theoretical paper is to draw attention to how psychiatrists can use their existing knowledge and skill set to inform their understanding of leadership theory and practice. In particular, the Psychodynamic Leadership Approach and Leader-Member Exchange theory are compared and contrasted to illustrate this point. The former represents a less well-known approach to leadership theory and practice whereas the latter is a widely familiar, conventional theory that is regularly taught in leadership courses. Both are underpinned by their emphasis on leader-follower relationships-and human relationships more broadly-and are intuitively appealing to psychiatrists endeavouring to understand aspects of organisational behaviour in the healthcare settings in which they work and lead. The application of these theories to assist reflection on and understanding of professional and personal leadership behaviours through leadership-oriented Balint-style groups and 360-degree appraisal is proposed. It is hoped that this paper will serve to stimulate thought and discussion about how leadership training for future psychiatrists can be tailored to better harness their existing competencies, thereby developing richer formative learning experiences and, ultimately, achieving superior leadership outcomes.

    A group of children with complex health care needs have emerged as a result of medical advances and government policies emphasizing the community as the arena for care. Some of these children remain dependent on the medical technology that enabled them to survive and require care of a complex and intensive nature to be carried out by their parents at home. To explore the experiences of families caring at home for a technology-dependent child; to examine their needs for practical and other support; and to examine how far services are currently meeting these needs. Methods In-depth interviews were conducted with the parents of 24 technology-dependent children and with 44 health, social care and other professionals. Services in the community were not sufficiently developed to support this group of families. Major problems were identified in the purchasing and provision of both short-term care/home support services and specialist equipment/therapies in the community. Service provision could be poorly planned and co-ordinated at an operational level and few families had a designated key worker. Parents felt that professionals did not always recognize either the emotional costs entailed in providing care of this nature or their expertise in caregiving. Information-giving to parents was often described as poor and participants reported that hospital professionals failed to negotiate the transfer of caregiving responsibility to parents. Services need to work in partnership with families and with each other at both strategic and operational levels, to develop integrated and co-ordinated services that can meet the needs of this group of families.

    The current study explores how competition and gaming expertise affect the satisfaction of competence needs and gaming gratifications. We demonstrate that competition moderates the effect of gaming expertise on the satisfaction of competence needs, which in turn affects game enjoyment and replay intention. Gaming expertise predicted players' need satisfaction, game enjoyment, and replay intention significantly better in a competitive compared to a noncompetitive context. The effect of gaming expertise on game enjoyment and replay intention was, furthermore, mediated by the satisfaction of competence needs. Finally, gaming expertise positively affected the importance of competition for players' self-esteem only in the competitive gaming context. The present findings demonstrate the importance of competition and gaming expertise for the satisfaction of competence needs, gaming gratifications, and the pursuit of self-esteem during gameplay, attesting to the applicability of self-determination theory to gaming contexts.

    In a sample of 263 male GO players at 48 levels of expertise and ranging from 18 to 78 years of age, it was found that factors of expertise deductive reasoning (EDR) and expertise working memory (EWM) were independent of factors of fluid reasoning (Gf) and short-term working memory (STWM) that, along with cognitive speed (Gs), have been found to characterize decline of intelligence in adulthood. The main effects of analyses of cross-sectional age differences indicated age-related decline in EDR and EWM as well as in Gf, STWM, and Gs. However, interaction and partialing analyses indicated that decline in EDR and EWM decreased to no decline with increase in level of expertise. The results thus suggest that with increase in factors known to raise the level of expertise--particularly, intensive, well-designed practice--there may be no age-related decline in the intelligence that is measured in the abilities of expertise.

    This paper puts forward a theoretical framework for the analysis of expertise and experts in contemporary societies. It argues that while prevailing approaches have come to see expertise in various forms and functions, they tend to neglect the broader historical and societal context, and importantly the relational aspect of expertise.

  2. Moral Expertise in the Clinic: Lessons Learned from Medicine and Science.

    Philosophers and others have questioned whether or not expertise in morality is possible. This debate is not only theoretical, but also affects the perceived legitimacy of clinical ethicists. One argument against moral expertise is that in a pluralistic society with competing moral theories no one can claim expertise regarding what another ought morally to do. There are simply too many reasonable moral values and intuitions that affect theory choice and its application; expertise is epistemically uniform. In this article, we discuss how similar concerns have recently threatened to undermine expertise in medicine and science. In contrast, we argue that the application of values is needed to exercise medical, scientific, and moral expertise. As long as these values are made explicit, worries about a pretense to authority in the context of a liberal democracy are ill-conceived. In conclusion, we argue for an expertise that is epistemically diverse. © The Author 2016. Published by Oxford University Press, on behalf of the Journal of Medicine and Philosophy Inc.

    Setting: The Desmond Tutu Tuberculosis (TB) Centre (DTTC), Stellenbosch University, South Africa. Objectives: 1) To determine whether access to designated funding is associated with the development of expertise in employees, and 2) which other factors are associated with the development of expertise in employees. Design: This was a retrospective study. The target population consisted of all employees at the DTTC during the period 1 January 2004 to 31 December 2011. Improvement in expertise during employment was the primary outcome; the secondary outcome was an increase in educational level linked to the National Qualifications Framework. Results: There was no association between access to funding and expertise development, but an association between the number of months employed and improvement of expertise during employment was observed (OR 1.03, 95%CI 1.02–1.04, P < 0.001), controlling for age at appointment, sex, access to designated funding and education level. Conclusion: The study shows that almost a third of employees increased their expertise, more than 90% had access to designated funding and personnel employed for a longer duration were more likely to experience improvements in expertise. We encourage research organisations in low- and middle-income countries to implement strategies to retain employees in order to build their expertise. PMID:26400709

  4. Nursing expertise: a course of ambiguity and evolution in a concept.

    2016-12-01

    In this article, we clarify and describe the nature of nursing expertise and provide a framework to guide its identification and further development. To have utility and rigour, concept-driven research and theories of practice require underlying concepts that are robust, valid and reliable. Advancing understanding of a concept requires careful attention to explicating its knowledge, metaphors and conceptual meaning. Examining the concepts and metaphors of nursing expertise, and how they have been interpreted into the nursing discourse, we aimed to synthesise definitions and similarities between concepts and elicit the defining characteristics and properties of nursing expertise. In clarifying the concept, we sought to move beyond the ambiguity that currently surrounds expertise in nursing and unravel it to make explicit the characteristics of nursing expertise from published peer-reviewed studies and structured literature synthesis. Findings indicate a lack of clarity surrounding the use of the term expertise. Traditional reliance upon intuition as a way of explaining expert performance is slowly evolving. Emerging from the analysis is a picture of expertise as the relationship between networks of contextual reasoning, understanding and practice. Striking absences in the discourse include limited explication of ethical reasoning and theorising a broader interpretation of expertise reflective of contemporary forms of nursing. © 2016 John Wiley & Sons Ltd.

  5. The transformation of (bio)ethics expertise in a world of ethical pluralism.

    PubMed

    Kovács, József

    2010-12-01

    Today, bioethics experts have an increasing role in public life. However, the question arises: what does bioethics expertise really mean? Can there be such a thing in our globalised world characterised by ethical pluralism? I will argue that bioethics as a discipline represents the transformation of ethics expertise from a hard to a soft form of it. Bioethics was born as a reaction to the growing awareness of ethical pluralism, and it denied the hard form of normative-prescriptive ethics expertise (the ability to determine what is the right course of action for others), particularly in its medical ethics form. In contrast, the traditional medical ethics model, and pre-modern societies in general, believed in hard normative ethics expertise. From this followed the characteristic paternalism of traditional medical practice: if physicians were experts in moral matters as well, if they knew what the right course of action to choose was, then they had a right to benevolently force this course of action on their patients. The remnants of this doctrine, although rarely stated explicitly, still can often be seen in clinical practice. The whole bioethics movement can be seen as a radical denial of the doctrine of physician's hard expertise in moral matters. Bioethics, however, represents a type of soft ethics expertise (mainly value sensitivity). Hence follows the seeming paradox of bioethics expertise: bioethics is both a denial of ethics expertise (in its hard form) as well as a type of (soft) ethics expertise.

    Visual expertise is the superior visual skill shown when executing domain-specific visual tasks. Understanding visual expertise is important in order to understand how the interpretation of medical images may be best learned and taught. In the context of this article, we focus on the visual skill of medical image diagnosis and, more specifically, on the methodological set-ups routinely used in visual expertise research. We offer a critique of commonly used methods and propose three challenges for future research to open up new avenues for studying characteristics of visual expertise in medical image diagnosis. The first challenge addresses theory development. Novel prospects in modelling visual expertise can emerge when we reflect on cognitive and socio-cultural epistemologies in visual expertise research, when we engage in statistical validations of existing theoretical assumptions and when we include social and socio-cultural processes in expertise development. The second challenge addresses the recording and analysis of longitudinal data. If we assume that the development of expertise is a long-term phenomenon, then it follows that future research can engage in advanced statistical modelling of longitudinal expertise data that extends the routine use of cross-sectional material through, for example, animations and dynamic visualisations of developmental data. The third challenge addresses the combination of methods. Alternatives to current practices can integrate qualitative and quantitative approaches in mixed-method designs, embrace relevant yet underused data sources and understand the need for multidisciplinary research teams. Embracing alternative epistemological and methodological approaches for studying visual expertise can lead to a more balanced and robust future for understanding superior visual skills in medical image diagnosis as well as other medical fields. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    Relevant evidence has shown that parasites process host-related information using chemical, visual, tactile, or auditory cues. However, the cues that are involved in the host-parasite interaction between Pediculus humanus capitis (De Geer 1767) and humans have not been identified yet. In this work, we studied the effect of human scalp components on the behavior of adult head lice. Filter paper segments were rubbed on volunteers' scalps and then placed in the experimental arena, where adult head lice were individually tested. The movement of the insects was recorded for each arena using the software EthoVision. Average movement parameters were calculated for the treatments in the bioassays such as total distance, velocity, number of times a head louse crossed between zones of the arena, and time in each zone of the arena. We found that scalp components induced head lice to decrease average locomotor activity and to remain arrested on the treated paper. The effect of the ageing of human scalp samples in the response of head lice was not statistically significant (i.e., human scalp samples of 4, 18, 40, and 60 h of ageing did not elicit a significant change in head louse behavior). When we analyzed the effect of the sex in the response of head lice to human scalp samples, males demonstrated significant differences. Our results showed for the first time the effect of host components conditioning head lice behavior. We discuss the role of these components in the dynamic of head lice infestation. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America.

    Transport networks are ubiquitous in multicellular organisms and include leaf veins, fungal mycelia and blood vessels. While transport of materials and signals through the network plays a crucial role in maintaining the living system, the transport capacity of the network can best be understood in terms of hydrodynamics. We report here that plasmodium from the large, single-celled amoeboid Physarum was able to construct a hydrodynamically optimized vein-network when evacuating biomass from confined arenas of various shapes through a narrow exit. Increasingly thick veins developed towards the exit, and the network spanned the arena via repetitive bifurcations to give a branching tree. The Hausdorff distance from all parts of the plasmodium to the vein network was kept low, whilst the hydrodynamic conductivity from distal parts of the network to the exit was equivalent, irrespective of the arena shape. This combination of spatial patterning and differential vein thickening served to evacuate biomass at an equivalent rate across the entire arena. The scaling relationship at the vein branches was determined experimentally to be 2.53-3.29, consistent with predictions from Murray’s law. Furthermore, we show that mathematical models for self-organised, adaptive transport in Physarum simulate the experimental network organisation well if the scaling coefficient of the current-reinforcement rule is set to 3. In simulations, this resulted in rapid development of an optimal network that minimised the combined volume and frictional energy in comparison with other scaling coefficients. This would predict that the boundary shear forces within each vein are constant throughout the network, and would be consistent with a feedback mechanism based on a sensing a threshold shear at the vein wall.

  9. Power in health care organizations: contemplations from the first-line management perspective.

    The aim of this paper is to examine health care organizations' power structures from the first-line management perspective. What liable power structures derive from the theoretical bases of bureaucratic, professional and result based organizations, and what power type do health care organizations represent, according to the empirical data? The paper seeks to perform an analysis using Mintzberg's power configurations of instrument, closed system, meritocracy and political arena. The empirical study was executed at the end of 2005 through a survey in ten Finnish hospital districts in both specialized and primary care. Respondents were all first-line managers in the area and a sample of staff members from internal disease, surgical and psychiatric units, as well as out-patient and primary care units. The number of respondents was 1,197 and the response percentage was 38. The data were analyzed statistically. As a result, it can be seen that a certain kind of organization structure supports the generation of a certain power type. A bureaucratic organization generates an instrument or closed system organization, a professional organization generates meritocracy and also political arena, and a result-based organization has a connection to political arena and meritocracy. First line managers regarded health care organizations as instruments when staff regarded them mainly as meritocracies having features of political arena. Managers felt their position to be limited by rules, whereas staff members regarded their position as having lots of space and influence potential. If the organizations seek innovative and active managers at the unit level, they should change the organizational structure and redistribute the work so that there could be more space for meaningful management. This research adds to the literature and gives helpful suggestions that will be of interest to those in the position of first-line management in health care.

    Developmental bisphenol A (BPA) exposure is associated with adverse behavioral effects, although underlying modes of action remain unclear. Because BPA is a suspected xenoestrogen, the objective was to identify sex-based changes in adult zebrafish social behavior developmentally exposed to BPA (0.0, 0.1 or 1 μM) or one of two control compounds (0.1μM 17β-estradiol [E2], and 0.1 μM GSK4716, a synthetic estrogen-related receptor γ ligand). A test chamber was divided lengthwise so each arena held one fish unable to detect the presence of the other fish. A mirror was inserted at one end of each arena; baseline activity levels were determined without mirror. Arenas were divided into 3, computer-generated zones to represent different distances from mirror image. Circadian rhythm patterns were evaluated at 1–3 (= AM) and 5–8 (= PM) hr postprandial. Adult zebrafish were placed into arenas and monitored by digital camera for 5 min. Total distance traveled, % time spent at mirror image, and number of attacks on mirror image were quantified. E2, GSK4716, and all BPA treatments dampened male activity and altered male circadian activity patterns; there was no marked effect on female activity. BPA induced non-monotonic effects (response curve changes direction within range of concentrations examined) on male % time at mirror only in AM. All treatments produced increased % time at the mirror during PM. Male attacks on the mirror were reduced by BPA exposure only during AM. There were sex-specific effects of developmental BPA on social interactions and time-of-day of observation affected results. PMID:25424546

    A series of experiments were conducted to determine the impact of Protaphorura fimata Gisin (Family: Onychiuridae) feeding on seeds and germinating seedlings of lettuce, Lactuca sativa L. (Asteraceae). First, various densities of P. fimata were incubated with 25 lettuce seeds for 7 d and feeding injury was evaluated in three soilless arena experiments. As a second step, 100 P. fimata were incubated with 25 lettuce seeds in three arena experiments with soil media. Finally, in a commercial field the incidence and impact of P. fimata on recently planted lettuce was assessed following applications of pyrethroid-insecticides: 2 d before planting, at planting, and 20 d later. In experiments without soil, the number of ungerminated seeds, feeding injury sites, and plants with injury were significantly greater in arenas with P. fimata than without. Similarly, the number of germinated seedlings, shoot fresh, and dry weights, and the length and width of fully opened-leaves were greater in arenas without than with P. fimata in assays with soil. In the field, P. fimata densities were significantly lower in beds that received insecticides at 2 d before and at planting than in untreated beds. Also, the fresh and dry weights of lettuce plants were significantly greater in the beds that received insecticide than in untreated. The results clearly show that P. fimata is a pest of lettuce and can cause severe feeding injury to germinating seeds or seedlings, thereby reducing their growth rate. The potential implications of P. fimata feeding and feeding injury characteristics are discussed. © The Authors 2015.

Moreover, results at the behavioral and neurophysiological levels reveal that musical expertise positively influences several aspects of speech processing, from auditory perception to speech production. In this review, we focus on the main results of the literature that led to the idea that musical expertise may benefit second language acquisition. We discuss several interpretations that may account for the influence of musical expertise on speech processing in native and foreign languages, and we propose new directions for future research.

    There is now international recognition of the importance of practice expertise in modern and effective health services. The Expertise in Practice Project in the United Kingdom began in May 1998 and continued to 2004. It included nurses working in all four countries of the United Kingdom, and it covered clinical specialists from pediatrics to palliative care. The project added to the current understanding of what nursing practice expertise is, through the identification and verification of attributes and factors which enable expert practice. The proposed framework offers a language for sharing what constitutes practice expertise and offers insight into what occurs between the expert practitioner and the people that experience their care. The Expertise in Practice Project demonstrates that nurses affect change and facilitate performance and organizational development.

    Clinical nursing expertise is central to quality patient care. Research on factors that contribute to expertise has focused largely on individual nurse characteristics to the exclusion of contextual factors. To address this, we examined effects of hospital contextual factors and individual nurse education and experience on clinical nursing expertise in a cross-sectional analysis of data from 8,611 registered nurses. In a generalized ordered logistic regression analysis, the composition of the hospital staff, particularly the proportion of nurses with at least a bachelor of science in nursing degree, was associated with significantly greater odds of a nurse reporting a more advanced expertise level. Our findings suggest that, controlling for individual characteristics, the hospital context significantly influences clinical nursing expertise. PMID:20645420

    Expertise effects for nonface objects in face-selective brain areas may reflect stable aspects of neuronal selectivity that determine how observers perceive objects. However, bottom-up (e.g., clutter from irrelevant objects) and top-down manipulations (e.g., attentional selection) can influence activity, affecting the link between category selectivity and individual performance. We test the prediction that individual differences expressed as neural expertise effects for cars in face-selective areas are sufficiently stable to survive clutter and manipulations of attention. Additionally, behavioral work and work using event related potentials suggest that expertise effects may not survive competition; we investigate this using functional magnetic resonance imaging. Subjects varying in expertise with cars made 1-back decisions about cars, faces, and objects in displays containing one or 2 objects, with only one category attended. Univariate analyses suggest car expertise effects are robust to clutter, dampened by reducing attention to cars, but nonetheless more robust to manipulations of attention than competition. While univariate expertise effects are severely abolished by competition between cars and faces, multivariate analyses reveal new information related to car expertise. These results demonstrate that signals in face-selective areas predict expertise effects for nonface objects in a variety of conditions, although individual differences may be expressed in different dependent measures depending on task and instructions.

    Previous research suggests that the size of the hippocampus can vary in response to intensive training (e.g., during the acquisition of expert knowledge). However, the role of the hippocampus in maintenance of skilled performance is not well understood. The Stanford/Veterans Affairs Aviation MRI Study offers a unique opportunity to observe the interaction of brain structure and multiple levels of expertise on longitudinal flight simulator performance. The current study examined the relationship between hippocampal volume and three levels of aviation expertise, defined by pilot proficiency ratings issued by the U.S. Federal Aviation Administration (11). At 3 annual time points, 60 pilots who varied in their level of aviation expertise (ages ranging from 45 to 69 yr) were tested. At baseline, higher expertise was associated with better flight simulator performance, but not with hippocampal volume. Longitudinally, there was an Expertise x Hippocampal volume interaction, in the direction that a larger hippocampus was associated with better performance at higher levels of expertise. These results are consistent with the notion that expertise in a cognitively demanding domain involves the interplay of acquired knowledge ('mental schemas') and basic hippocampal-dependent processes.

  1. Developing expertise in surgery.

    PubMed

    Alderson, David

    2010-01-01

    The concept of expertise is widely embraced but poorly defined in surgery. Dictionary definitions differentiate between authority and experience, while a third view sees expertise as a mind-set rather than a status. Both absolute and relative models of expertise have been developed, and each allows a richer understanding of the application of these concepts to emerge. Trainees must develop both independent and interdependent expertise, and an appreciation of the essentially constructivist and uncertain nature of medical knowledge. Approach may be more important than innate talent; the concepts of 'flow', sustained 'deliberate practice' and 'adaptive expertise' are examples of expert approaches to learning. Non-analytical reasoning plays a key role in decision making at expert levels of practice. A technically gifted surgeon may be seen as a safety hazard rather than an expert if inter-dependent expertise has not been developed. Key roles of a surgical educator are to facilitate the development of an expert approach to education and to enable entry into and movement towards the centre of an expert community of practice.

    2013-12-01

    A quantitative method for estimating an expected uncertainty (reliability and validity) in assessment results arising from the relativity between four variables, viz examiner's expertise, examinee's expertise achieved, assessment task difficulty and examinee's performance, was developed for the complex assessment applicable to final year project thesis assessment including peer assessment. A guide map can be generated by the method for finding expected uncertainties prior to the assessment implementation with a given set of variables. It employs a scale for visualisation of expertise levels, derivation of which is based on quantified clarities of mental images for levels of the examiner's expertise and the examinee's expertise achieved. To identify the relevant expertise areas that depend on the complexity in assessment format, a graphical continuum model was developed. The continuum model consists of assessment task, assessment standards and criterion for the transition towards the complex assessment owing to the relativity between implicitness and explicitness and is capable of identifying areas of expertise required for scale development.

  3. Imaging Magnetic Vortices Dynamics Using Lorentz Electron Microscopy with GHz Excitations

    2015-03-01

    Magnetic vortices in thin films are naturally formed spiral spin configurations with a core polarization pointing out of the film plane. They typically represent ground states with high structural and thermal stability as well as four different chirality-polarity combinations, offering great promise in the development of spin-based devices. For applications to spin oscillators, non-volatile memory and logic devices, the fundamental understanding and precise control of vortex excitations and dynamic switching behavior are essential. The compact dimensionality and fast spin dynamics set grand challenges for direct imaging technologies. Recently, we have developed a unique method to directly visualize the dynamic magnetic vortex motion using advanced Lorentz electron microscopy combined with GHz electronic excitations. It enables us to map the orbit of a magnetic vortex core in a permalloy square with <5nm resolution and to reveal subtle changes of the gyrotropic motion as the vortex is driven through resonance. Further, in multilayer spin-valve disks, we probed the strongly coupled coaxial vortex motion in the dipolar- and indirect exchange-coupled regimes and unraveled the underlying coherence and modality. Our approach is complementary to X-ray magnetic circular dichroism and is of general interest to the magnetism community as it paves a way to study fundamental spin phenomena with unprecedented resolution and accuracy.

    2005-12-01

    Cardiovascular health programs face a growing and not often recognized challenge--the aging of the American population. During this century, all states will experience a dramatic rise in the number of older adults. By 2030, approximately 20% of Americans will be over the age of 65. This article describes the prevalence of cardiovascular disease among older adults, the public health and aging services networks, selected results and recommendations from the Aging States Project, and examples of ongoing aging activities relevant to cardiovascular health programs being promoted by the U.S. Centers for Disease Control and Prevention (CDC). State health departments (SHDs) and state units on aging (SUAs) bring different resources, approaches, and partners to address older adult health but many aspects are complementary. The aging services network is extensive, and in one form or another, can reach older adults in virtually every community in the country. Based on a survey of SHDs and SUAs, which was part of the Aging States Project, respondents identified cardiovascular disease as the most common health concern (57% of SHDs and 55% of SUAs). However, fewer than half of those responding reported having cardiovascular health programs directed at older adults (37% of SHDs and 40% of SUAs). Initial activities are described in the arenas of strategic partnerships, data for action, and capacity building based on recommendations from the survey findings. These examples are provided as potential models for current and future state cardiovascular health programs wanting to enhance their reach to older adults.

    2017-05-01

    There is increasing awareness of the detrimental health impact of frailty on older adults and of the high prevalence of malnutrition in this segment of the population. Experts in these 2 arenas need to be cognizant of the overlap in constructs, diagnosis, and treatment of frailty and malnutrition. There is a lack of consensus regarding the definition of malnutrition and how it should be assessed. While there is consensus on the definition of frailty, there is no agreement on how it should be measured. Separate assessment tools exist for both malnutrition and frailty; however, there is intersection between concepts and measures. This narrative review highlights some of the intersections within these screening/assessment tools, including weight loss/decreased body mass, functional capacity, and weakness (handgrip strength). The potential for identification of a minimal set of objective measures to identify, or at least consider risk for both conditions, is proposed. Frailty and malnutrition have also been shown to result in similar negative health outcomes and consequently common treatment strategies have been studied, including oral nutritional supplements. While many of the outcomes of treatment relate to both concepts of frailty and malnutrition, research questions are typically focused on the frailty concept, leading to possible gaps or missed opportunities in understanding the effect of complementary interventions on malnutrition. A better understanding of how these conditions overlap may improve treatment strategies for frail, malnourished, older adults.

    Klinestiver, L.R.

    Psychophysiological factors are not uncommon terms in the aviation incident/accident investigation sequence where human error is involved. It is highly suspect that the same psychophysiological factors may also exist in the industrial arena where operator personnel function; but, there is little evidence in literature indicating how management and subordinates cope with these factors to prevent or reduce accidents. It is apparent that human factors psychophysological training is quite evident in the aviation industry. However, while the industrial arena appears to analyze psychophysiological factors in accident investigations, there is little evidence that established training programs exist for supervisors and operator personnel.

    An experimental group of homing pigeons ( Columba livia f. domestica) learned to associate food with a magnetic anomaly produced by bar magnets that were fixed to the bowl in which they received their daily food ration in their home loft; the control group lacked this experience. Both groups were trained to search for two hidden food depots in a rectangular sand-filled arena without obvious visual cues; for the experimental birds, these depots were also marked with three 1.15 × 106 μT bar magnets. During the tests, there were two food depots, one marked with the magnets, the other unmarked; their position within the arena was changed from test to test. The experimental birds searched within 10 cm of the magnetically marked depot in 49% of the test sessions, whereas the control birds searched there in only 11% of the sessions. Both groups searched near the control depot in 11 and 13% of the sessions, respectively. The significant preference of the magnetically marked food depot by the experimental birds shows that homing pigeons cannot only detect a magnetic anomaly but can also use it as a cue for locating hidden food in an open arena.

    NASA ER-2 # 809 and its DC-8 shown in Arena Arctica before the SAGE III Ozone Loss and Validation Experiment (SOLVE). The two airborne science platforms were based north of the Arctic Circle in Kiruna, Sweden, during the winter of 2000 to study ozone depletion as part of SOLVE. A large hangar built especially for research, "Arena Arctica" housed the instrumented aircraft and the scientists. Scientists have observed unusually low levels of ozone over the Arctic during recent winters, raising concerns that ozone depletion there could become more widespread as in the Antarctic ozone hole. The NASA-sponsored international mission took place between November 1999 and March 2000 and was divided into three phases. The DC-8 was involved in all three phases returning to Dryden between each phase. The ER-2 flew sample collection flights between January and March, remaining in Sweden from Jan. 9 through March 16. "The collaborative campaign will provide an immense new body of information about the Arctic stratosphere," said program scientist Dr. Michael Kurylo, NASA Headquarters. "Our understanding of the Earth's ozone will be greatly enhanced by this research."

    Previous research has shown that social support is important for health and performance at work, but there is a lack of research regarding managers' social support at work, and if it needs to be improvedOBJECTIVE:To investigate managers' perception of work-related social support, and facilitators and hindrances that influence their seeking of social support at work. Semi-structured interviews with sixty-two managers in two Swedish organizations. Work-related support, which strengthened their managerial image of being competent, was sought from sources within the workplace. Sensitive and personal support, where there was a risk of jeopardizing their image of being competent, was sought from sources outside the workplace. Access to arenas for support (location of the workplace, meetings, and vocational courses) and the managerial role could facilitate their support-seeking, but could also act as hindrances. Because attending different arenas for support were demanding, they refrained from seeking support if the demands were perceived as too high. Different supportive sources are distinguished based on what supportive function they have and in which arenas they are found, in order to preserve the confidence of the closest organization and to maintain the image of being a competent and performing manager.

    Zebrafish (Danio rerio) are emerging as a useful model organism for neuroscience research. Mounting evidence suggests that various traditional rodent paradigms may be adapted for testing zebrafish behavior. The open field test is a popular rodent test of novelty exploration, recently applied to zebrafish research. To better understand fish novelty behavior, we exposed adult zebrafish to two different open field arenas for 30 min, assessing the amount and temporal patterning of their exploration. While (similar to rodents) zebrafish scale their locomotory activity depending on the size of the tank, the temporal patterning of their activity was independent of arena size. These observations strikingly parallel similar rodent behaviors, suggesting that spatio-temporal strategies of animal exploration may be evolutionarily conserved across vertebrate species. In addition, we found interesting oscillations in zebrafish exploration, with the per-minute distribution of their horizontal activity demonstrating sinusoidal-like patterns. While such patterning is not reported for rodents and other higher vertebrates, a nonlinear regression analysis confirmed the oscillation patterning of all assessed zebrafish behavioral endpoints in both open field arenas, revealing a potentially important aspect of novelty exploration in lower vertebrates.

    Emerging research highlights the promise of community- and policy-level strategies in preventing youth violence. Large-scale economic developments, such as sports and entertainment arenas and casinos, may improve the living conditions, economics, public health, and overall wellbeing of area residents and may influence rates of violence within communities. To assess the effect of community economic development efforts on neighborhood residents' perceptions on violence, safety, and economic benefits. Telephone survey in 2011 using a listed sample of randomly selected numbers in six Pittsburgh neighborhoods. Descriptive analyses examined measures of perceived violence and safety and economic benefit. Responses were compared across neighborhoods using chi-square tests for multiple comparisons. Survey results were compared to census and police data. Residents in neighborhoods with the large-scale economic developments reported more casino-specific and arena-specific economic benefits. However, 42% of participants in the neighborhood with the entertainment arena felt there was an increase in crime, and 29% of respondents from the neighborhood with the casino felt there was an increase. In contrast, crime decreased in both neighborhoods. Large-scale economic developments have a direct influence on the perception of violence, despite actual violence rates.

    Managers can do many things to improve organizational performance, but the accomplishments of the most skillful employees often are most important. This article makes the point that managers should be aware of employee expertise and its relationship to organizational performance. The article also describes the components of an organizational culture of employee expertise. An organizational culture of employee expertise builds on the learning organization metaphor that has frequently appeared in the management literature. How employees develop expertise to do their jobs is emerging as a critical issue for organizations, and managers will likely play a key role in that process.

    The most common lethal accidents in General Aviation are caused by improperly executed landing approaches in which a pilot descends below the minimum safe altitude without proper visual references. To understand how expertise might reduce such erroneous decision-making, we examined relevant neural processes in pilots performing a simulated landing approach inside a functional MRI scanner. Pilots (aged 20–66) were asked to “fly” a series of simulated “cockpit view” instrument landing scenarios in an MRI scanner. The scenarios were either high risk (heavy fog–legally unsafe to land) or low risk (medium fog–legally safe to land). Pilots with one of two levels of expertise participated: Moderate Expertise (Instrument Flight Rules pilots, n = 8) or High Expertise (Certified Instrument Flight Instructors or Air-Transport Pilots, n = 12). High Expertise pilots were more accurate than Moderate Expertise pilots in making a “land” versus “do not land” decision (CFII: d′ = 3.62±2.52; IFR: d′ = 0.98±1.04; p<.01). Brain activity in bilateral caudate nucleus was examined for main effects of expertise during a “land” versus “do not land” decision with the no-decision control condition modeled as baseline. In making landing decisions, High Expertise pilots showed lower activation in the bilateral caudate nucleus (0.97±0.80) compared to Moderate Expertise pilots (1.91±1.16) (p<.05). These findings provide evidence for increased “neural efficiency” in High Expertise pilots relative to Moderate Expertise pilots. During an instrument approach the pilot is engaged in detailed examination of flight instruments while monitoring certain visual references for making landing decisions. The caudate nucleus regulates saccade eye control of gaze, the brain area where the “expertise” effect was observed. These data provide evidence that performing “real world” aviation tasks in an fMRI provide objective data regarding the relative expertise of pilots and brain regions involved in it. PMID:25426935

    Interactions between parents and healthcare professionals are essential when parents of children with chronic conditions are learning to share expertise about clinical care, but limited evidence exists on how they actually interact. This paper discusses the use of focused ethnography in paediatric settings as an effective means of exploring attitudes towards expertise. The paper draws on repeated observations, interviews and field-notes involving the parents of six children with chronic kidney disease, and 28 healthcare professionals at two, tertiary, children's hospital-based units. Data were analysed using the Framework approach and the concepts of expertise and self-management. Our study highlighted rewards and challenges associated with focused ethnography in this context. Rewards included the ability to gain a richer understanding of the complex phenomena of mutual acknowledgement of expertise that occurs during parent/ healthcare professional interactions. Challenges related to gaining informed consent and ensuring potential participants had an adequate understanding of the purpose of the study. Two dimensions of parental expertise around their child (personal and clinical) were evident in our data. Parents' and professionals' expertise about the child and their condition was acknowledged and exchanged as parents learnt to share clinical-care with the multi-disciplinary team. Healthcare professionals acknowledged parents' need to understand aspects of each of the eight disciplinary knowledge bases relating to their child's management and recognised parents' expert knowledge of their child, found ways to mobilise this knowledge, and wove parents' expertise into the management plan. Parents spoke of the degree to which their own expert knowledge of their child complemented healthcare professionals' clinical knowledge. However, ambivalence around expertise was evident as both parents and healthcare professionals questioned what the expertise was, and who the expert was. Our discussion focuses on the ways healthcare professionals and parents share expertise around the child's condition as parents take on responsibility for home-based clinical care. Our findings point to focused ethnography being an effective way of capturing new insights into parent and professional interactions in a paediatric setting and mutual acknowledgement of expertise; these insights may help redress the reported limitations of previous, retrospective studies.

    Under a conventional two-arm randomised trial design, participants are allocated to an intervention and participating health professionals are expected to deliver both interventions. However, health professionals often have differing levels of expertise in a skill-based interventions such as surgery or psychotherapy. An expertise-based approach to trial design, where health professionals only deliver an intervention in which they have expertise, has been proposed as an alternative. The aim of this project was to systematically review the use of an expertise-based trial design in the medical literature. We carried out a comprehensive search of nine databases--AMED, BIOSIS, CENTRAL, CINAHL, Cochrane Methodology Register, EMBASE, MEDLINE, Science Citation Index, and PsycINFO--from 1966 to 2012 and performed citation searches using the ISI Citation Indexes and Scopus. Studies that used an expertise-based trial design were included. Two review authors independently screened the titles and abstracts and assessed full-text reports. Data were extracted and summarised on the study characteristics, general and expertise-specific study methodology, and conduct. In total, 7476 titles and abstracts were identified, leading to 43 included studies (54 articles). The vast majority (88%) used a pure expertise-based design; three (7%) adopted a hybrid design, and two (5%) used a design that was unclear. Most studies compared substantially different interventions (79%). In many cases, key information relating to the expertise-based design was absent; only 12 (28%) reported criteria for delivering both interventions. Most studies recruited the target sample size or very close to it (median of 101, interquartile range of 94 to 118), although the target was reported for only 40% of studies. The proportion of participants who received the allocated intervention was high (92%, interquartile range of 82 to 99%). While use of an expertise-based trial design is growing, it remains uncommon. Reporting of study methodology and, particularly, expertise-related methodology was poor. Empirical evidence provided some support for purported benefits such as high levels of recruitment and compliance with allocation. An expertise-based trial design should be considered but its value seems context-specific, particularly when interventions differ substantially or interventions are typically delivered by different health professionals.

  17. The role of domain expertise and judgment in dealing with unexpected events

    NASA Astrophysics Data System (ADS)

    Kochan, Janeen Adrion

    Unexpected events, particularly those creating surprise, interrupt ongoing mental and behavioral processes, creating an increased potential for unwanted outcomes to the situation. Human reactions to unexpected events vary. One can hypothesize a number of reasons for this variation, including level of domain expertise, previous experience with similar events, emotional connotation, and the contextual surround of the event. Whereas interrupting ongoing activities and focusing attention temporarily on a surprising event may be a useful evolutionary response to a threatening situation, the same process may be maladaptive in today's highly dynamic world. The purpose of this study was to investigate how different aspects of expertise affected one's ability to detect and react to an unexpected event. It was hypothesized that there were two general types of expertise, domain expertise and judgment (Hammond, 2000), which influenced one's performance on dealing with an unexpected event. The goal of the research was to parse out the relative contribution of domain expertise, so the role of judgment could be revealed. The research questions for this study were: (a) Can we identify specific knowledges and skills which enhance one's ability to deal with unexpected events? (b) Are these skills "automatically" included in domain expertise? (c) How does domain expertise improve or deter one's reaction and response to unexpected events? (d) What role does judgment play in responding to surprise? The general hypothesis was that good judgment would influence the process of surprise at different stages and in different ways than would domain expertise. The conclusions from this research indicated that good judgment had a significant positive effect in helping pilots deal with unexpected events. This was most pronounced when domain expertise was low.

    Using both patient-focused and donor-focused perspectives, to review the current EU blood directives, in order to derive proposals, in principle, for what should evolve during the revision process of these directives. Review of the EU blood directives in the light of scientific literature, related reports from the Directorate General Health and Consumers (DG SANTÉ), and from the Council of Europe (CoE). The analyses led us to present the main following proposals: developing voluntary unpaid donations: the directives should consider taking into consideration ethically acceptable forms of compensation consistent with altruistic donation (including plasma donations for fractionation); current expertise: more extensive utilization of the expertise of blood establishments and their consultants should be considered; donor selection: an evidence-based approach for basing donor deferral criteria on sound scientific evidence should be promoted; donor reactions: measures to prevent donor reactions and to make donations safer for the donors should also be included; quality control: The quality control requirements should relate to the Council of Europe Blood Guide specifications: these should become minimum standards (as is the case with monographs of the European Pharmacopeia), facilitating regular update of blood component lists and related specifications and compliance with the specifications; haemovigilance: because of reporting difficulties (e.g. lack of number of blood products transfused), the effectiveness of haemovigilance has so far been limited. This should lead appropriate bodies to investigate alternative or complementary ways to help improve patient safety, taking into consideration, in principle, patient blood management and the appropriate use of blood products. Furthermore, donor vigilance, which is still absent from the current directive should be included in a revised directive. These proposals for revising the current EU blood directives (if taken into account and given appropriate regulatory formulation) should help to optimize patient safety and donor care, progress the compliance with the ethical principles for donors and improve the efficiency of the healthcare systems dedicated to transfusion medicine.

    Expertise effects for nonface objects in face-selective brain areas may reflect stable aspects of neuronal selectivity that determine how observers perceive objects. However, bottom-up (e.g., clutter from irrelevant objects) and top-down manipulations (e.g., attentional selection) can influence activity, affecting the link between category selectivity and individual performance. We test the prediction that individual differences expressed as neural expertise effects for cars in face-selective areas are sufficiently stable to survive clutter and manipulations of attention. Additionally, behavioral work and work using event related potentials suggest that expertise effects may not survive competition; we investigate this using functional magnetic resonance imaging. Subjects varying in expertise with cars made 1-back decisions about cars, faces, and objects in displays containing one or 2 objects, with only one category attended. Univariate analyses suggest car expertise effects are robust to clutter, dampened by reducing attention to cars, but nonetheless more robust to manipulations of attention than competition. While univariate expertise effects are severely abolished by competition between cars and faces, multivariate analyses reveal new information related to car expertise. These results demonstrate that signals in face-selective areas predict expertise effects for nonface objects in a variety of conditions, although individual differences may be expressed in different dependent measures depending on task and instructions. © The Author 2014.

    A much-debated question in object recognition is whether expertise for faces and expertise for non-face objects utilize common perceptual information. We investigated this issue by assessing the diagnostic information required for different types of expertise. Specifically, we asked whether face categorization and expert car categorization at the subordinate level relies on the same spatial frequency (SF) scales. Fifteen car experts and fifteen novices performed a category verification task with spatially filtered images of faces, cars, and airplanes. Images were categorized based on their basic (e.g. "car") and subordinate level (e.g. "Japanese car") identity. The effect of expertise was not evident when objects were categorized at the basic level. However, when the car experts categorized faces and cars at the subordinate level, the two types of expertise required different kinds of SF information. Subordinate categorization of faces relied on low SFs more than on high SFs, whereas subordinate expert car categorization relied on high SFs more than on low SFs. These findings suggest that expertise in the recognition of objects and faces do not utilize the same type of information. Rather, different types of expertise require different types of diagnostic visual information.

    The objective of this study was to measure the effect size of three important factors in manual material handling, namely expertise, lifting height and weight lifted. The effect of expertise was evaluated by contrasting 15 expert and 15 novice handlers, the effect of the weight lifted with a 15-kg box and a 23-kg box and the effect of lifting height with two different box heights: ground level and a 32 cm height. The task consisted of transferring a series of boxes from a conveyor to a hand trolley. Lifting height and weight lifted had more effect size than expertise on external back loading variables (moments) while expertise had low impact. On the other hand, expertise showed a significant effect of posture variables on the lumbar spine and knees. All three factors are important, but for a reduction of external back loading, the focus should be on the lifting height and weight lifted. The objective was to measure the effect size of three important factors in a transfer of boxes from a conveyor to a hand trolley. Lifting height and weight lifted had more effect size than expertise on external back loading variables but expertise was a major determinant in back posture.

    Search for responsibility in medicine became everyday. Anaesthetists are particularly exposed and will be, several times, confronted to it during their career. They have to have knowledge of some necessary elements to get to grips with expertise. Expertise can be asked by a penal jurisdiction. In that case, the anaesthetist can be directly and personally implicationed. When expertise is asked by a civil jurisdiction, it concerns anaesthetists, whichever the (liberal or employee of private). Expertise during administrative procedures concern hospital's anaesthetists. It is important to organize a preparatory meeting in any expertise. Praticians must collect together the complete medical file to establish the most exactly possible, chronology of facts. The anaesthetist can be accompanied by medical consultant appointed by the insurance companies and a lawyer. But he does not have to content with be represented by them. Presence in expertise is essential; praticians can so give evidence of their good faith and answer the expert's questions. Vagueness or doubt are never favorable to pratician. It is also, a responsible and respectful behavior toward the patient.

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

    This study investigated the electrocortical correlates of art expertise, as defined by a newly developed, content-valid and internally consistent 23-item art expertise questionnaire in N=27 participants that varied in their degree of art expertise. Participants viewed each 50 paintings, filtering-distorted versions of these paintings and plain colour stimuli under free-viewing conditions whilst the EEG was recorded from 64 channels. Results revealed P3b-/LPC-like bilateral posterior event-related potentials (ERP) that were larger over the right hemisphere than over the left hemisphere. Art expertise correlated negatively with the amplitude of the ERP responses to paintings and control stimuli. We conclude that art expertise is associated with reduced ERP responses to visual stimuli in general that can be considered to reflect increased neural efficiency due to extensive practice in the contemplation of visual art.

  7. The Curse of Expertise: When More Knowledge Leads to Miscalibrated Explanatory Insight.

    2016-07-01

    Does expertise within a domain of knowledge predict accurate self-assessment of the ability to explain topics in that domain? We find that expertise increases confidence in the ability to explain a wide variety of phenomena. However, this confidence is unwarranted; after actually offering full explanations, people are surprised by the limitations in their understanding. For passive expertise (familiar topics), miscalibration is moderated by education; those with more education are accurate in their self-assessments (Experiment 1). But when those with more education consider topics related to their area of concentrated study (college major), they also display an illusion of understanding (Experiment 2). This "curse of expertise" is explained by a failure to recognize the amount of detailed information that had been forgotten (Experiment 3). While expertise can sometimes lead to accurate self-knowledge, it can also create illusions of competence. Copyright © 2015 Cognitive Science Society, Inc.

    Worked examples are very effective for novice learners. They typically present a written-out ideal (didactical) solution for learners to study. This study used worked examples of patient history taking in physiotherapy that presented a non-didactical solution (i.e., based on actual performance). The effects of model expertise (i.e., worked example based on advanced, third-year student model or expert physiotherapist model) in relation to students' expertise (i.e., first- or second-year) were investigated. One hundred and thirty-four physiotherapy students (61 first-year and 73 second-year). Design was 2 × 2 factorial with factors 'Student Expertise' (first-year vs. second-year) and 'Model Expertise' (expert vs. advanced student). Within expertise levels, students were randomly assigned to the Expert Example or the Advanced Student Example condition. All students studied two examples (content depending on their assigned condition) and then completed a retention and test task. They rated their invested mental effort after each example and test task. Second-year students invested less mental effort in studying the examples, and in performing the retention and transfer tasks than first-year students. They also performed better on the retention test, but not on the transfer test. In contrast to our hypothesis, there was no interaction between student expertise and model expertise: all students who had studied the Expert examples performed better on the transfer test than students who had studied Advanced Student Examples. This study suggests that when worked examples are based on actual performance, rather than an ideal procedure, expert models are to be preferred over advanced student models.

    There is a critical need for improved diagnosis of tuberculosis in children, particularly in young children with intrathoracic disease as this represents the most common type of tuberculosis in children and the greatest diagnostic challenge. There is also a need for standardized clinical case definitions for the evaluation of diagnostics in prospective clinical research studies that include children in whom tuberculosis is suspected but not confirmed by culture of Mycobacterium tuberculosis. A panel representing a wide range of expertise and child tuberculosis research experience aimed to develop standardized clinical research case definitions for intrathoracic tuberculosis in children to enable harmonized evaluation of new tuberculosis diagnostic technologies in pediatric populations. Draft definitions and statements were proposed and circulated widely for feedback. An expert panel then considered each of the proposed definitions and statements relating to clinical definitions. Formal group consensus rules were established and consensus was reached for each statement. The definitions presented in this article are intended for use in clinical research to evaluate diagnostic assays and not for individual patient diagnosis or treatment decisions. A complementary article addresses methodological issues to consider for research of diagnostics in children with suspected tuberculosis.

  10. Instruction of Multidisciplinary Content in Introductory Courses

    2017-01-01

    There has been an ever-increasing emphasis on the integration of material in the areas of science, technology, engineering and mathematics during the past decade or so. However, there are two major requirements for accomplishing the effective delivery of such multidisciplinary content in the classroom: having high levels of expertise in all of the subjects; and, having the ability to combine the separate fields in a consistent manner without compromising academic purity. The research reported here involves a teacher with this skill set and it includes an example from kinematics, which is initially explored with standard treatment of concepts in mechanics and then developed with analysis employing algebra. As often happens, the non-trivial nature of the result in this case does not readily allow students to have a sense that the physics-based outcome is correct. This shortfall is remedied by adopting a complementary approach with geometry and calculus, which adds an independent perspective that reassures students by confirming the validity of the original answer. The enhanced quality of instruction achieved with the above methodology produces many benefits, including greater student understanding and more opportunities for active involvement by students in the learning process.

  11. Crowdsourcing Knowledge Discovery and Innovations in Medicine

    2014-01-01

    Clinicians face difficult treatment decisions in contexts that are not well addressed by available evidence as formulated based on research. The digitization of medicine provides an opportunity for clinicians to collaborate with researchers and data scientists on solutions to previously ambiguous and seemingly insolvable questions. But these groups tend to work in isolated environments, and do not communicate or interact effectively. Clinicians are typically buried in the weeds and exigencies of daily practice such that they do not recognize or act on ways to improve knowledge discovery. Researchers may not be able to identify the gaps in clinical knowledge. For data scientists, the main challenge is discerning what is relevant in a domain that is both unfamiliar and complex. Each type of domain expert can contribute skills unavailable to the other groups. “Health hackathons” and “data marathons”, in which diverse participants work together, can leverage the current ready availability of digital data to discover new knowledge. Utilizing the complementary skills and expertise of these talented, but functionally divided groups, innovations are formulated at the systems level. As a result, the knowledge discovery process is simultaneously democratized and improved, real problems are solved, cross-disciplinary collaboration is supported, and innovations are enabled.

    Synthetic biology is capable of delivering new solutions to key challenges spanning the bioeconomy, both nationally and internationally. Recognising this significant potential and the associated need to facilitate its translation and commercialisation the UK government commissioned the production of a national Synthetic Biology Roadmap in 2011, and subsequently provided crucial support to assist its implementation. Critical infrastructural investments have been made, and important strides made towards the development of an effectively connected community of practitioners and interest groups. A number of Synthetic Biology Research Centres, DNA Synthesis Foundries, a Centre for Doctoral Training, and an Innovation Knowledge Centre have been established, creating a nationally distributed and integrated network of complementary facilities and expertise. The UK Synthetic Biology Leadership Council published a UK Synthetic Biology Strategic Plan in 2016, increasing focus on the processes of translation and commercialisation. Over 50 start-ups, SMEs and larger companies are actively engaged in synthetic biology in the UK, and inward investments are starting to flow. Together these initiatives provide an important foundation for stimulating innovation, actively contributing to international research and development partnerships, and helping deliver useful benefits from synthetic biology in response to local and global needs and challenges.

    Spacecraft contamination programs exist in five independent AFSC organizations: Geophysics Laboratory (GL), Arnold Engineering and Development Center (AEDC), Rome Air Development Center (RADC/OSCE), Wright Research and Development Center (MLBT), Armament Laboratory (ATL/SAI), and Space Systems Division (SSD/OL-AW). In addition, a sizable program exists at Aerospace Corp. These programs are complementary, each effort addressing a specific area of expertise: GL's effort is aimed at addressing the effects of on-orbit contamination; AEDC's effort is aimed at ground simulation and measurement of optical contamination; RADC's effort addresses the accumulation, measurement, and removal of contamination on large optics; MLBT's effort is aimed at understanding the effect of contamination on materials; ATL's effort is aimed at understanding the effect of plume contamination on systems; SSD's effort is confined to the integration of some contamination experiments sponsored by SSD/CLT; and Aerospace Corp.'s effort is aimed at supporting the needs of the using System Program Offices (SPO) in specific areas, such as contamination during ground handling, ascent phase, laboratory measurements aimed at understanding on-orbit contamination, and mass loss and mass gain in on-orbit operations. These programs are described in some detail, with emphasis on GL's program.

    The diagnosis of malignant biliary strictures remains problematic, especially in the perihilar region and in primary sclerosing cholangitis (PSC). Conventional cytology obtained during endoscopic retrograde cholangiography (ERC)-guided brushings of biliary strictures is suboptimal due to limited sensitivity, albeit it remains the gold standard with a high specificity. Emerging technologies are being developed and validated to address this pressing unmet patient need. Such technologies include enhanced visualization of the biliary tree by cholangioscopy, intraductal ultrasound, and confocal laser endomicroscopy. Conventional cytology can be aided by employing complementary and advanced cytologic techniques such as fluorescent in situ hybridization (FISH), and this technique should be widely adapted. Interrogation of bile and serum by examining extracellular vesicle number and cargo, and exploiting next-generation sequencing and proteomic technologies, is also being explored. Examination of circulating cell-free deoxyribonucleic acid (cfDNA) for differentially methylated regions is a promising test which is being rigorously validated. The special expertise required for these analyses has to date hampered their validation and adaptation. Herein, we will review these emerging technologies to inform the reader of the progress made and encourage further studies, as well as adaptation of validated approaches.

    Aerial photography has a long history of being employed for mapping purposes due to some of its main advantages, including large area imaging from above and minimization of field work. Since few years multi-camera aerial systems are becoming a practical sensor technology across a growing geospatial market, as complementary to the traditional vertical views. Multi-camera aerial systems capture not only the conventional nadir views, but also tilted images at the same time. In this paper, a particular use of such imagery in the field of building inspection as well as disaster assessment is addressed. The main idea is to inspect a building from four cardinal directions by using monoplotting functionalities. The developed application allows to measure building height and distances and to digitize man-made structures, creating 3D surfaces and building models. The realized GUI is capable of identifying a building from several oblique points of views, as well as calculates the approximate height of buildings, ground distances and basic vectorization. The geometric accuracy of the results remains a function of several parameters, namely image resolution, quality of available parameters (DEM, calibration and orientation values), user expertise and measuring capability.

    The identification of certain genomic alterations (EGFR, ALK, ROS1, BRAF) or immunological markers (PD-L1) in tissues or cells has led to targeted treatment for patients presenting with late stage or metastatic lung cancer. These biomarkers can be detected by immunohistochemistry (IHC) and/or by molecular biology (MB) techniques. These approaches are often complementary but depending on, the quantity and quality of the biological material, the urgency to get the results, the access to technological platforms, the financial resources and the expertise of the team, the choice of the approach can be questioned. The possibility of detecting simultaneously several molecular targets, and of analyzing the degree of tumor mutation burden and of the micro-satellite instability, as well as the recent requirement to quantify the expression of PD-L1 in tumor cells, has led to case by case development of algorithms and international recommendations, which depend on the quality and quantity of biological samples. This review will highlight the different predictive biomarkers detected by IHC for treatment of lung cancer as well as the present advantages and limitations of this approach. A number of perspectives will be considered. PMID:29534030

  19. The Energy Forum of Sri Lanka: Working toward appropriate expertise

    NASA Astrophysics Data System (ADS)

    Nieusma, Dean

    Taking my cue from the knowledge base and practices comprising appropriate technology development, and building on politics of expertise scholarship, this dissertation develops the concept of appropriate expertise: the combination of social and technical competences required to address marginalization through technological interventions. The dissertation asks what appropriate expertise looks like "on the ground" in the context of development as practiced by an exceptional group of technology designers from the Energy Forum of Sri Lanka: What design goals did they strive toward? What challenges did they face? What strategies did they employ? In an effort to answer these questions, the dissertation looks at how these designers interacted across a range of contexts with a broad spectrum of people and institutions, each with its own expertise to draw upon. In particular, it looks at how they situated their work in a highly contoured field of social power, where different types of expertise were used as resources for reinforcing or resisting existing power relations. I use the concept relations of expertise to denote the structure of expert interactions across multiple contexts of activity. Although this concept links to broad political-economic conditions that order varied expert practices, my analytic focus is at a different level: the situated experiences of expert practitioners. By starting with ground-level practices and understandings, I argue that creating new relations of expertise---that is, changing the nature of the interactions among experts and between experts and those they work with---is the key way my informants worked to legitimate marginalized perspectives and thereby empower marginalized social groups around technology-development practices. Appropriate expertise enables the creation of appropriate technologies, but it does more. It enables the creation of new relations of expertise, both through inspiring new forms of interpersonal interaction surrounding technology development and through incremental modification of existing decision-making structures to allow a more diverse group stakeholders to come together around technology decision making in the context of development.

  20. Developing the experts we need: Fostering adaptive expertise through education.

    In this era of increasing complexity, there is a growing gap between what we need our medical experts to do and the training we provide them. While medical education has a long history of being guided by theories of expertise to inform curriculum design and implementation, the theories that currently underpin our educational programs do not account for the expertise necessary for excellence in the changing health care context. The more comprehensive view of expertise gained by research on both clinical reasoning and adaptive expertise provides a useful framing for re-shaping physician education, placing emphasis on the training of clinicians who will be adaptive experts. That is, have both the ability to apply their extensive knowledge base as well as create new knowledge as dictated by patient needs and context. Three key educational approaches have been shown to foster the development of adaptive expertise: learning that emphasizes understanding, providing students with opportunities to embrace struggle and discovery in their learning, and maximizing variation in the teaching of clinical concepts. There is solid evidence that a commitment to these educational approaches can help medical educators to set trainees on the path towards adaptive expertise. © 2018 John Wiley & Sons, Ltd.

    Expertise with encoding material has been shown to aid long-term memory for that material. It is not clear how relevant this expertise is for image memorability (e.g., radiologists' memory for radiographs), and how robust over time. In two studies, we tested scene memory using a standard long-term memory paradigm. One compared the performance of radiologists to naïve observers on two image sets, chest radiographs and everyday scenes, and the other radiologists' memory with immediate as opposed to delayed recognition tests using musculoskeletal radiographs and forest scenes. Radiologists' memory was better than novices for images of expertise but no different for everyday scenes. With the heterogeneity of image sets equated, radiologists' expertise with radiographs afforded them better memory for the musculoskeletal radiographs than forest scenes. Enhanced memory for images of expertise disappeared over time, resulting in chance level performance for both image sets after weeks of delay. Expertise with the material is important for visual memorability but not to the same extent as idiosyncratic detail and variability of the image set. Similar memory decline with time for images of expertise as for everyday scenes further suggests that extended familiarity with an image is not a robust factor for visual memorability.

    Clinical scholarship has been conceptualised and theorised in the nursing literature for over 30 years but no research has captured nurses' clinicians' views on how it differs or is the same as clinical expertise and clinical leadership. The aim of this study was to determine clinical nurses' understanding of the differences and similarities between the clinical expert, clinical leader and clinical scholar. A descriptive interpretative qualitative approach using semi-structured interviews with 18 practising nurses from Australia, Canada and England. The audio-taped interviews were transcribed and the text coded for emerging themes. The themes were sorted into categories of clinical expert, clinical leader and clinical scholarship as described by the participants. These themes were then compared and contrasted and the essential elements that characterise the nursing roles of the clinical expert, clinical leader and clinical scholar were identified. Clinical experts were seen as linking knowledge to practice with some displaying clinical leadership and scholarship. Clinical leadership is seen as a positional construct with a management emphasis. For the clinical scholar they linked theory and practice and encouraged research and dissemination of knowledge. There are distinct markers for the roles of clinical expert, clinical leader and clinical scholar. Nurses working in one or more of these roles need to work together to improve patient care. An 'ideal nurse' may be a blending of all three constructs. As nursing is a practice discipline its scholarship should be predominantly based on clinical scholarship. Nurses need to be encouraged to go beyond their roles as clinical leaders and experts to use their position to challenge and change through the propagation of knowledge to their community.

    Purpose Carrying out minor surgery procedures in the primary care setting is popular with patients, cost effective and delivers at least as good outcomes as those performed in the hospital setting. This paper aims to describe the central role of clinical leadership in developing an accreditation system for general practitioners (GPs) undertaking community-based surgery in the Irish national setting where no mandatory accreditation process currently exists. Design/methodology/approach In all, 24 GPs were recruited to the GP network. Ten pilot standards were developed addressing GPs' experience and training, clinical activity and practice supporting infrastructure and tested, using information and document review, prospective collection of clinical data and a practice inspection visit. Two additional components were incorporated into the project (patient satisfaction survey and self-audit). A multi-modal evaluation was undertaken. A majority of GPs was included at all stages of the project, in line with the principles of action learning. The steering group had a majority of GPs with relevant expertise and representation of all other actors in the minor surgery arena. The GP research network contributed to each stage of the project. The project lead was a GP with minor surgery experience. Quantitative data collected were analysed using Predictive Analytic SoftWare. Krueger's framework analysis approach was used to analyse the qualitative data. Findings A total of 9 GPs achieved all standards at initial review, 14 successfully completed corrective actions and 1 GP did not achieve the required standard. Standards were then amended to reflect findings and a supporting framework was developed. Originality/value The flexibility of the action-learning approach and the clinical leadership design allowed for the development of robust quality standards in a short timeframe.

    Magnetic materials play a vital role in technologies ranging from those concerning the day-to-day life of man to special applications in nuclear, space, defense and health sectors. Despite several notable developments in theoretical and experimental fronts in the area of magnetism and magnetic materials and the ever increasing number of researchers and engineers actively engaged in these topics, only a few international conferences are being organized in these topics in Asia. To address this lacuna, the second edition of International Conference on Magnetic Materials and Applications - 2013 (MagMA-2013) was jointly hosted and organized by Indian Institute of Technology Guwahati (IITG) under the auspicious of Magnetics Society of India (MSI). MagMA-2013 devoted special sessions for (A) Soft and Hard Magnetic Materials and their Applications, (B) Magnetic Thin Films, Particles and Nanostructures, (C) Magnetic Recording, Memories, and Spintronics, (D) Strongly Correlated Electron System, (E) Fundamental Magnetic Properties and Cooperative Phenomena, (F) Novel Magnetic Materials and Device Applications, (G) Magnet Industry - Product and Marketing and (H) Interdisciplinary Topics in Magnetism. These sessions included plenary and invited talks by speakers drawn from the international arena who shared their expertise and experiences on recent developments in various topics such as (1) conventional (bulk and powder metallurgy processed) soft and hard magnetic materials, (2) novel forms (nanostructured, particulate/granular, composite, thin film and multilayered films) of soft and hard magnetic materials and their hybrids, (3) sensors and actuators based on magnetoresistive, magnetostrictive, magnetoelastic and magnetoimpedance materials, (4) magnetic storage and its trends, (5) multi-disciplinary area of bio-magnetism and applications of magnetic materials in medicine, (6) newly emerging interdisciplinary topics in magnetism and (7) recent progress in theoretical and computational techniques in magnetism.

  5. Social communication: a potent force for change.

    Some of the strongest challenges to established communication structures emerge from the development arena. 1 element of the challenges comes from those working to place communication between deprived communities and those providing them expertise at the center of development planning. Communication specialists maintain that human communication is the pivot on which balances the success or failure of the whole process of development as well as individual programs. Yet, the vast majority of development programs are conceived and executed without a serious communication component. Communication personnel are irritated by the approach of planning first, and communicating only after a failure. As more and more after the fact appeals are heard, it is becoming clearer to planners that communication is more than another hardware component consisting of posters, radio messages, and so on, but a central and decisive factor of any program. The attempt to raise communications to a more appropriate place in the development context has been aided greatly by recent evidence of its impact. Among those who must be classified as successful in fully investigating their target group and understanding how to communicate with them are the commercial manufacturers. Their advertising campaigns have revolutionized consumption habits and lifestyles across the world. An increasing number of voices, recognizing the impact of commercial advertising, are advocating that their techniques be adopted in the promotion of social development. Richard Manoff is one experienced advertising man who has used his commercial skills to promote developmental messages. He maintains that there is no idea that cannot be promoted as are commercial products. Changes in communication strategies will not by themselves eliminate the most fundamental problem facing humanity, i.e., the eradication of poverty, but they can contribute to that goal. A comprehensive communication strategy can help awaken people to release their energies in the service of development.

    Relationships between non-avian theropod dinosaurs and extant and fossil birds are a major focus of current paleobiological research. Despite extensive phylogenetic and morphological support, behavioural evidence is mostly ambiguous and does not usually fossilize. Thus, inferences that dinosaurs, especially theropods displayed behaviour analogous to modern birds are intriguing but speculative. Here we present extensive and geographically widespread physical evidence of substrate scraping behavior by large theropods considered as compelling evidence of "display arenas" or leks, and consistent with "nest scrape display" behaviour among many extant ground-nesting birds. Large scrapes, up to 2 m in diameter, occur abundantly at several Cretaceous sites in Colorado. They constitute a previously unknown category of large dinosaurian trace fossil, inferred to fill gaps in our understanding of early phases in the breeding cycle of theropods. The trace makers were probably lekking species that were seasonally active at large display arena sites. Such scrapes indicate stereotypical avian behaviour hitherto unknown among Cretaceous theropods, and most likely associated with terrirorial activity in the breeding season. The scrapes most probably occur near nesting colonies, as yet unknown or no longer preserved in the immediate study areas. Thus, they provide clues to paleoenvironments where such nesting sites occurred.

    The goal of the 1987 Airborne Antarctic Ozone Experiment was to improve the understanding of the mechanisms involved in the formation of the Antarctic ozone hole. Total ozone data taken by the Nimbus-7 Total Ozone Mapping Spectrometer (TOMS) played a central role in the successful outcome of the experiment. During the experiment, the near-real-time TOMS total ozone observations were supplied within hours of real time to the operations center in Punta Arenas, Chile. The final report summarizes the role which Research and Data Systems (RDS) Corporation played in the support of the experiment. The RDS provided telecommunications to support the science and operations efforts for the Airborne Antarctic Ozone Experiment, and supplied near real-time weather information to ensure flight and crew safety; designed and installed the telecommunications network to link NASA-GSFC, the United Kingdom Meteorological Office (UKMO), Palmer Station, the European Center for Medium-Range Weather Forecasts (ECMWF) to the operation at Punta Arenas; engineered and installed stations and other stand-alone systems to collect data from designated low-orbiting polar satellites and beacons; provided analyses of Nimbus-7 TOMS data and backup data products to Punta Arenas; and provided synoptic meteorological data analysis and reduction.

    To examine whether the outcome of a rat's own choices ("personal information") and the choice behavior of another rat ("social information") can jointly control spatial choices, rats were tested in an open field task in which they searched for food. For the rats of primary interest (Subject Rats), the baited locations were all on one side of the arena, but the specific locations baited and the side on which they occurred varied over trials. The Subject Rats were sometimes tested together with an informed "Model" rat that had learned to find food in the same five locations (all on the same side of the arena) on every trial. Unintended perceptual cues apparently controlled spatial choices at first, but when perceptual cues to food location were not available, choices were controlled by both personal information (allowing the baited side of the arena to be determined) and social information (allowing baited locations to be determined more precisely). This shows that control by personal and social information are not mutually exclusive and supports the view that these two kinds of information can be used flexibly and adaptively to guide spatial choices.

    An individual's sexual drive is influenced by genotype, experience and environmental conditions. How these factors interact to modulate sexual behaviors remains poorly understood. In Drosophila melanogaster, environmental cues, such as food availability, affect mating activity offering a tractable system to investigate the mechanisms modulating sexual behavior. In D. melanogaster, environmental cues are often sensed via the chemosensory gustatory and olfactory systems. Here, we present a method to test the effect of environmental chemical cues on mating behavior. The assay consists of a small mating arena containing food medium and a mating couple. The mating frequency for each couple is continuously monitored for 24 h. Here we present the applicability of this assay to test environmental compounds from an external source through a pressurized air system as well as manipulation of the environmental components directly in the mating arena. The use of a pressurized air system is especially useful to test the effect of very volatile compounds, while manipulating components directly in the mating arena can be of value to ascertain a compound's presence. This assay can be adapted to answer questions about the influence of genetic and environmental cues on mating behavior and fecundity as well as other male and female reproductive behaviors.

    Background. Emerging research highlights the promise of community- and policy-level strategies in preventing youth violence. Large-scale economic developments, such as sports and entertainment arenas and casinos, may improve the living conditions, economics, public health, and overall wellbeing of area residents and may influence rates of violence within communities. Objective. To assess the effect of community economic development efforts on neighborhood residents' perceptions on violence, safety, and economic benefits. Methods. Telephone survey in 2011 using a listed sample of randomly selected numbers in six Pittsburgh neighborhoods. Descriptive analyses examined measures of perceived violence and safety and economic benefit. Responses were compared across neighborhoods using chi-square tests for multiple comparisons. Survey results were compared to census and police data. Results. Residents in neighborhoods with the large-scale economic developments reported more casino-specific and arena-specific economic benefits. However, 42% of participants in the neighborhood with the entertainment arena felt there was an increase in crime, and 29% of respondents from the neighborhood with the casino felt there was an increase. In contrast, crime decreased in both neighborhoods. Conclusions. Large-scale economic developments have a direct influence on the perception of violence, despite actual violence rates. PMID:26273310

    Many ants rely on both visual cues and self-generated chemical signals for navigation, but their relative importance varies across species and context. We evaluated the roles of both modalities during colony emigration by Temnothorax rugatulus. Colonies were induced to move from an old nest in the center of an arena to a new nest at the arena edge. In the midst of the emigration the arena floor was rotated 60°around the old nest entrance, thus displacing any substrate-bound odor cues while leaving visual cues unchanged. This manipulation had no effect on orientation, suggesting little influence of substrate cues on navigation. When this rotation was accompanied by the blocking of most visual cues, the ants became highly disoriented, suggesting that they did not fall back on substrate cues even when deprived of visual information. Finally, when the substrate was left in place but the visual surround was rotated, the ants' subsequent headings were strongly rotated in the same direction, showing a clear role for visual navigation. Combined with earlier studies, these results suggest that chemical signals deposited by Temnothorax ants serve more for marking of familiar territory than for orientation. The ants instead navigate visually, showing the importance of this modality even for species with small eyes and coarse visual acuity. PMID:23671713

    This study explores how antipredator behaviour of juvenile Atlantic salmon Salmo salar developed during conventional hatchery rearing of eggs from wild brood stock, compared with the behaviour of wild-caught juveniles from the same population. Juveniles aged 1+ years were tested in two unfamiliar environments; in one S. salar were presented with simulated predator attacks and in the other they were given the opportunity to explore an open-field arena. No difference was found in their spontaneous escape responses or ventilation rate (reflex responses) after simulated predator attacks. Hatchery-reared juveniles were more risk-prone in their behaviours than wild-caught individuals. Hatchery juveniles stayed less time in association with shelter. In the open-field arena, hatchery juveniles were more active than wild juveniles. Hatchery juveniles were also immobile for less time and spent a shorter amount of time than wild juveniles in the fringe of the open-field arena. Salmo salar size had no effect on the observed behaviour. Overall, this study provides empirical evidence that one generation of hatchery rearing does not change reflex responses associated with threats, whereas antipredator behaviour, typically associated with prior experience, was less developed in hatchery-reared than in wild individuals. © 2017 The Fisheries Society of the British Isles.

  15. Social impact bonds and their application to preventive health.

    PubMed

    Fitzgerald, John L

    2013-05-01

    Although preventive health in Australia has been acknowledged as central to national health and wellbeing, efforts to reform the delivery of preventive health have to date produced limited results. The financing of preventive health at a national level is based on outcome- or performance-based funding mechanisms; however, delivery of interventions and activities at a state level have not been subjected to outcome-based funding processes. A new financing tool being applied in the area of social services (social impact bonds) has emerged as a possible model for application in the prevention arena. This paper explores key issues in the consideration of this funding model in the prevention arena. When preventive health is conceptualised as a merit good, the role of government is clarified and outcome measures fully articulated, social impact bonds may be a viable funding option to supplement core public health activities. WHAT IS KNOWN ABOUT THE TOPIC? The complexities of outcome monitoring in preventive health are well understood.Likewise, the problem of linking funding to outcomes from preventive health practice has also been debated at length in health policy. However, not much is known about the application of social impact bonds into the preventive health arena.WHAT DOES THIS PAPER ADD? This paper discusses the limitations and opportunities facing the application of the social impact bond financing model in the preventive health arena. This has not been undertaken previously.WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS? Social impact bonds have received significant recent attention from federal and state government treasury departments as potential financing tools for government. Health policy practitioners are watching this space very closely to see the outcomes of a New South Wales trial. Health promotion practitioners and primary care practitioners who deliver preventive services will need to keep abreast of this issue as it will have significant impact on their practice if states and territories introduce outcome-based funding processes.

  16. Connecting rehabilitation and everyday life--the lived experiences among women with stress-related ill health.

    The aim was to describe and understand how connecting rehabilitation experiences and everyday life was characterised in the lived experiences during the rehabilitation in women with stress-related ill health. Five women were interviewed on three occasions during a rehabilitation programme and once 3 months later. Data were analysed using the Empirical, Phenomenological and Psychological method. The participants experienced connections between their rehabilitation and their previous, present and future everyday life influencing both rehabilitation and everyday life in a back-and-forth process. These connections were experienced in mind or in doing, mostly targeting the private arena in everyday life. Connecting rehabilitation experiences to their working situations was more challenging and feelings of frustration and being left alone were experienced. Although the participants described constructive connections between rehabilitation experiences and the private arena in everyday life, they mostly failed to experience connections that facilitated a positive return to work. Recommended support in the return to work process in rehabilitation comprises the provision of practical work-related activities during rehabilitation; being supportive in a constructive dialogue between the participant and the workplace, and continuing this support in follow-ups after the actual rehabilitation period. Rehabilitation for persons with stress-related ill health needs to focus on the private arena as well as the work situation in everyday life. Creative activities may enable experiences that inspire connections in mind and connections targeting the private arena in everyday life. The work situation needs to be thoroughly discussed during rehabilitation for enabling the participants to experience a support in the return to work process. Rehabilitation including practical work-related activities, support in a constructive dialogue between the participant and the manager at the workplace, and continued support in follow-ups targeting the workplace might be beneficial for successfully return to work.

  17. Emotionality in growing pigs: is the open field a valid test?

    The ability to assess emotionality is important within animal welfare research. Yet, for farm animals, few tests of emotionality have been well validated. Here we investigated the construct validity of behavioural measures of pig emotionality in an open-field test by manipulating the experiences of pigs in three ways. In Experiment One (pharmacological manipulation), pigs pre-treated with Azaperone, a drug used to reduce stress in commercial pigs, were more active, spent more time exploring and vocalised less than control pigs. In Experiment Two (social manipulation), pigs that experienced the open-field arena with a familiar companion were also more exploratory, spent less time behaviourally idle, and were less vocal than controls although to a lesser degree than in Experiment One. In Experiment Three (novelty manipulation), pigs experiencing the open field for a second time were less active, explored less and vocalised less than they had done in the first exposure to the arena. A principal component analysis was conducted on data from all three trials. The first two components could be interpreted as relating to the form (cautious to exploratory) and magnitude (low to high arousal) of the emotional response to open-field testing. Based on these dimensions, in Experiment One, Azaperone pigs appeared to be less fearful than saline-treated controls. However, in Experiment Two, exposure to the arena with a conspecific did not affect the first two dimensions but did affect a third behavioural dimension, relating to oro-nasal exploration of the arena floor. In Experiment Three, repeat exposure altered the form but not the magnitude of emotional response: pigs were less exploratory in the second test. In conclusion, behavioural measures taken from pigs in an open-field test are sensitive to manipulations of their prior experience in a manner that suggests they reflect underlying emotionality. Behavioural measures taken during open-field exposure can be useful for making assessments of both pig emotionality and of their welfare. Copyright © 2011 Elsevier Inc. All rights reserved.

    2013-05-01

    Although research in science education has led to new assessment forms and functions, the reality is that little work has been done to unpack and capture what it means for a teacher to develop expertise at assessing science. The purpose of this paper is two-fold. First, I suggest a conceptualization of assessment expertise that is organized around three dimensions: (a) designing aligned and theoretically cohesive assessment (Design), (b) using assessment to support students' science learning (Use), and (c) equitably assessing language minorities (Equity). The second purpose is to suggest and exemplify various levels of teaching expertise across the three conceptual dimensions using written assessment plans gathered from a study on secondary science pre-service teachers' assessment growth. The contribution of this paper lies in its further conceptual development of assessment expertise, instantiated in a rubric, which can spark discussion about how to capture the range of assessment practices that might be found in science classrooms as well as move toward a potential learning progression of assessment expertise.

    Three hundred and three female participants between the ages of 18 and 77 reported their experience in crafting (sewing, knitting, and crocheting) and completed a measure of spatial ability: The Paper Folding Test. To investigate the connection between spatial ability performance, age, and craft expertise, an ANOVA was conducted for the Paper Folding Test using two levels of crafting expertise (High and Low) and three age categories (younger adults: 18-39, middle-aged adults: 40-59, and older adults: 60-77). Performance on the spatial ability test declined with age as predicted from previous literature. However, there was a significant Age by Expertise interaction. No difference was found between High and Low craft expertise groups in younger adults (18-39), but there was a growing difference between expertise groups in middle-aged adults (40-59) and older adults (60-77). The results suggest that continued hands-on experience in spatial domains is a predictor of maintenance of spatial ability across the life span.

  4. Bridging long proxy data time series and instrumental observation in the Virtual Institute of Integrated Climate and Landscape Evolution Analyses - ICLEA

    Understanding causes and effects of present-day climate change on landscapes and the human habitat faces two main challenges, (i) too short time series of instrumental observation that do not cover the full range of variability since mechanisms of climate change and landscape evolution work on different time scales, which often not susceptible to human perception, and, (ii) distinct regional differences due to the location with respect to oceanic/continental climatic influences, the geological underground, and the history and intensity of anthropogenic land-use. Both challenges are central for the ICLEA research strategy and demand a high degree of interdisciplinary. In particular, the need to link observations and measurements of ongoing changes with information from the past taken from natural archives requires joint work of scientists with very different time perspectives. On the one hand, scientists that work at geological time scales of thousands and more years and, on the other hand, those observing and investigating recent processes at short time scales. The GFZ, Greifswald University and the Brandenburg University of Technology together with their partner the Polish Academy of Sciences strive for focusing their research capacities and expertise in ICLEA. ICLEA offers young researchers an interdisciplinary and structured education and promote their early independence through coaching and mentoring. Postdoctoral rotation positions at the ICLEA partner institutions ensure mobility of young researchers and promote dissemination of information and expertise between disciplines. Training, Research and Analytical workshops between research partners of the ICLEA virtual institute are another important measure to qualify young researchers. The long-term mission of the Virtual Institute is to provide a substantiated data basis for sustained environmental maintenance based on a profound process understanding at all relevant time scales. Aim is to explore processes of climate and landscape evolution in an historical cultural landscape extending from northeastern Germany into northwestern Poland. The northern-central European lowlands will be facilitated as a natural laboratory providing an ideal case for utilizing a systematic and holistic approach. In ICLEA five complementary work packages (WP) are established according to the key research aspects. WP 1 focused on monitoring mainly hydrology and soil moisture as well as meteorological parameters. WP 2 is linking present day and future monitoring data with the most recent past through analyzing satellite images. This WP will further provide larger spatial scales. WP 3-5 focus on different natural archives to obtain a broad variety of high quality proxy data. Tree rings provide sub-seasonal data for the last centuries up to few millennia, varved lake sediments cover the entire research time interval at seasonal to decadal resolution and palaeosoils and geomorphological features also cover the entire period but not continuously and with lower resolution. Complementary information, like climate, tree ecophysiological and limnological data etc., are provided by cooperation with associated partners. Further information about ICLEA: www.iclea.de

    To present the varied approaches of 9 complementary and alternative medicine (CAM) institutions (all grantees of the National Center for Complementary and Alternative Medicine) used to develop faculty expertise in research literacy and evidence-based practice (EBP) in order to integrate these concepts into CAM curricula. A survey to elicit information on the faculty development initiatives was administered via e-mail to the 9 program directors. All 9 completed the survey, and 8 grantees provided narrative summaries of faculty training outcomes. The grantees found the following strategies for implementing their programs most useful: assess needs, develop and adopt research literacy and EBP competencies, target early adopters and change leaders, employ best practices in teaching and education, provide meaningful incentives, capitalize on resources provided by grant partners, provide external training opportunities, and garner support from institutional leadership. Instructional approaches varied considerably across grantees. The most common were workshops, online resources, in-person short courses, and in-depth seminar series developed by the grantees. Many also sent faculty to intensive multiday extramural training programs. Program evaluation included measuring participation rates and satisfaction and the integration of research literacy and EBP learning objectives throughout the academic curricula. Most grantees measured longitudinal changes in beliefs, attitudes, opinions, and competencies with repeated faculty surveys. A common need across all 9 CAM grantee institutions was foundational training for faculty in research literacy and EBP. Therefore, each grantee institution developed and implemented a faculty development program. In developing the framework for their programs, grantees used strategies that were viewed critical for success, including making them multifaceted and unique to their specific institutional needs. These strategies, in conjunction with the grantees' instructional approaches, can be of practical use in other CAM and non-CAM academic environments considering the introduction of research literacy and EBP competencies into their curricula.

    New approaches are required to address the needs of complex undiagnosed diseases patients. These approaches include clinical genomic diagnostic pipelines, utilizing intra- and multi-disciplinary platforms, as well as specialty-specific genomic clinics. Both are advancing diagnostic rates. However, complementary cross-disciplinary approaches are also critical to address those patients with multisystem disorders who traverse the bounds of multiple specialties and remain undiagnosed despite existing intra-specialty and genomic-focused approaches. The diagnostic possibilities of undiagnosed diseases include genetic and non-genetic conditions. The focus on genetic diseases addresses some of these disorders, however a cross-disciplinary approach is needed that also simultaneously addresses other disorder types. Herein, we describe the initiation and summary outcomes of a public health system approach for complex undiagnosed patients - the Undiagnosed Diseases Program-Western Australia (UDP-WA). Briefly the UDP-WA is: i) one of a complementary suite of approaches that is being delivered within health service, and with community engagement, to address the needs of those with severe undiagnosed diseases; ii) delivered within a public health system to support equitable access to health care, including for those from remote and regional areas; iii) providing diagnoses and improved patient care; iv) delivering a platform for in-service and real time genomic and phenomic education for clinicians that traverses a diverse range of specialties; v) retaining and recapturing clinical expertise; vi) supporting the education of junior and more senior medical staff; vii) designed to integrate with clinical translational research; and viii) is supporting greater connectedness for patients, families and medical staff. The UDP-WA has been initiated in the public health system to complement existing clinical genomic approaches; it has been targeted to those with a specific diagnostic need, and initiated by redirecting existing clinical and financial resources. The UDP-WA supports the provision of equitable and sustainable diagnostics and simultaneously supports capacity building in clinical care and translational research, for those with undiagnosed, typically rare, conditions.

  7. The Influence of Peer Reviewer Expertise on the Evaluation of Research Funding Applications

    Although the scientific peer review process is crucial to distributing research investments, little has been reported about the decision-making processes used by reviewers. One key attribute likely to be important for decision-making is reviewer expertise. Recent data from an experimental blinded review utilizing a direct measure of expertise has found that closer intellectual distances between applicant and reviewer lead to harsher evaluations, possibly suggesting that information is differentially sampled across subject-matter expertise levels and across information type (e.g. strengths or weaknesses). However, social and professional networks have been suggested to play a role in reviewer scoring. In an effort to test whether this result can be replicated in a real-world unblinded study utilizing self-assessed reviewer expertise, we conducted a retrospective multi-level regression analysis of 1,450 individual unblinded evaluations of 725 biomedical research funding applications by 1,044 reviewers. Despite the large variability in the scoring data, the results are largely confirmatory of work from blinded reviews, by which a linear relationship between reviewer expertise and their evaluations was observed—reviewers with higher levels of self-assessed expertise tended to be harsher in their evaluations. However, we also found that reviewer and applicant seniority could influence this relationship, suggesting social networks could have subtle influences on reviewer scoring. Overall, these results highlight the need to explore how reviewers utilize their expertise to gather and weight information from the application in making their evaluations. PMID:27768760

  8. Exploring nursing expertise in residential care for older people: a mixed method study.

    2016-10-01

    To explore the expertise of Registered Nurses in residential care for older people. As older people in residential care have many complex dependencies, nursing expertise is an essential component of care excellence. However, the work of these nurses can be invisible and, therefore, unrecognized. Thus, additional attention is required to illuminate such nursing expertise. A mixed method design was used in this study. The research took place in 2012 in the Republic of Ireland. Twenty-three case study nurses were recruited from nursing homes. Each case study nurse involved five data collection methods: shadowing, interview with a colleague, interview with a resident, a demographic profile and a director of nursing survey. The study was also informed by a modified focus group. Qualitative data were analysed using directed content analysis using a conceptual framework generated from the literature on nursing expertise. Quantitative data were analysed using SPSS and presented in descriptive statistics. The findings from the case studies and the modified focus group are presented in seven themes, which represent nursing expertise in residential care of older people: transitions, context of the nursing home, saliency, holistic practice knowledge, knowing the resident, moral agency and skilled know how. Nursing expertise in residential care of older people is a complex phenomenon which encompasses many aspects of care delivery in a person-centred framework. By rendering this expertise visible, the need for appropriate and adequate skill mix for a growing residential care population is presented. © 2016 John Wiley & Sons Ltd.

    Both the medical care and public health systems have invested considerable resources to define, measure, and improve quality and health outcomes. A movement toward accountability has generated performance indicators from the medical arena and “leading health indicators” from the public health arena. The focus on specific conditions by the medical care system has been at odds with public health’s emphasis on improving population health and has perpetuated a bifurcated system. Aligning the goals of medical care with those of public health will require reformulation of performance measurement and accountability into a common language that is valued by both systems. Such a creation would amount to a whole that is stronger than the sum of the component parts. PMID:12604482

    Policies are examined which, if implemented, could lead to significant energy savings in intercity travel in the northeast corridor arena, without restricting the traveler's freedom of mode choice. The effects on arena energy consumption of introducing new, more energy-efficient aircraft are investigated; and several strategies unrelated to the implementation of new aircraft are introduced to yield reductions in overall intercity energy use. In both parts of this analysis, resulting changes in patronage (modal share) and energy use are demonstrated, leading to new insights into the effectiveness of different potential policies for achieving energy conservation. Some observations on induced demand trends that could be associated with certain strategies and the resultant potential effect on energy conservation are provided.

  9. The paradoxical politics of provider reempowerment.

    PubMed

    Brown, Lawrence D; Eagan, Elizabeth

    2004-12-01

    The recent decline, indeed perhaps dismantling, of managed care is sometimes treated as both consequence and cause of the political reempowerment of medical providers, whose professional dominance managed care had challenged. Drawing evidence from Round III of the Community Tracking Study of the Center for Studying Health System Change, this article reviews the politics of four "arenas" of managed care regulation--prompt payment, mandated benefits, external appeals, and financial solvency--and concludes that the power of providers is contingent on patterns of coalition and conflict that differ across the discrete arenas. The zero-sum connotations of the "de" and "re" empowerment of providers under managed care fail to capture the subtlety of providers' search for fresh cultural, economic, and political resources in shifting policy contexts.

    The Lunar Regolith Excavation Competition is a new competition that needs graphics, logos, rules, as well as an arena. Although this is the first year of the competition, the competition is modeled after an existing competition, the Centennial Lunar Excavator Challenge. This competition however is aimed at college students. This makes the challenge identifying key aspects of the original competition and modeling them to fit into an easier task, and creating exciting advertisement that helps encourage participation. By using a youth focus group, young insight, as well as guiding advice from experts in the field, hopefully an arena can be designed and built, rules can be molded and created to fit, and alluring graphics can be printed to bring about a successful first year of the Lunar Regolith Excavation Competition.

  12. Global health priorities – priorities of the wealthy?

    Health has gained importance on the global agenda. It has become recognized in forums where it was once not addressed. In this article three issues are considered: global health policy actors, global health priorities and the means of addressing the identified health priorities. I argue that the arenas for global health policy-making have shifted from the public spheres towards arenas that include the transnational for-profit sector. Global health policy has become increasingly fragmented and verticalized. Infectious diseases have gained ground as global health priorities, while non-communicable diseases and the broader issues of health systems development have been neglected. Approaches to tackling the health problems are increasingly influenced by trade and industrial interests with the emphasis on technological solutions. PMID:15847685

    Abstract. Expertise with encoding material has been shown to aid long-term memory for that material. It is not clear how relevant this expertise is for image memorability (e.g., radiologists’ memory for radiographs), and how robust over time. In two studies, we tested scene memory using a standard long-term memory paradigm. One compared the performance of radiologists to naïve observers on two image sets, chest radiographs and everyday scenes, and the other radiologists’ memory with immediate as opposed to delayed recognition tests using musculoskeletal radiographs and forest scenes. Radiologists’ memory was better than novices for images of expertise but no different for everyday scenes. With the heterogeneity of image sets equated, radiologists’ expertise with radiographs afforded them better memory for the musculoskeletal radiographs than forest scenes. Enhanced memory for images of expertise disappeared over time, resulting in chance level performance for both image sets after weeks of delay. Expertise with the material is important for visual memorability but not to the same extent as idiosyncratic detail and variability of the image set. Similar memory decline with time for images of expertise as for everyday scenes further suggests that extended familiarity with an image is not a robust factor for visual memorability. PMID:26870748

  14. Comment [on “Science in the political arena: Taking fire from the right and the left”

    The points made in “Science in the Political Arena: Taking Fire From the Right and the Left” [Eos, Nov. 21, 1995, p. 480] are well taken. However, I disagree strongly with the implication that assaults on science from the right and left are of equal gravity. While the assault from the left disrupts certain scientific projects, the assault from the right, I believe, risks America's preeminence in science and the development of significant benefits to society. Although environmentalists and animal-rights activists have certainly impeded research in some cases, their activism has also spurred many other fields of research including global change and biodiversity, and encouraged the development of fresh water supplies and alternative fuel sources.

    The hippocampal formation (HF) plays a crucial role in amniote spatial cognition. There are also indications of functional lateralization in the contribution of the left and right HF in processes that enable birds to navigate space. The experiments described in this study were designed to examine left and right HF differences in a task of sun compass-based spatial learning in homing pigeons (Columba livia). Control, left (HFL) and right (HFR) HF lesioned pigeons were trained in an outdoor arena to locate a food reward using their sun compass in the presence or absence of alternative feature cues. Subsequent to training, the pigeons were subjected to test sessions to determine if they learned to represent the goal location with their sun compass and the relative importance of the sun compass vs. feature cues. Under all test conditions, the control pigeons demonstrated preferential use of the sun compass in locating the goal. By contrast, the HFL pigeons demonstrated no ability to locate the goal by the sun compass but an ability to use the feature cues. The behaviour of the HFR pigeons demonstrated that an intact left HF is sufficient to support sun compass-based learning, but in conflict situations and in contrast to controls, they often relied on feature cues. In conclusion, only the left HF is capable of supporting sun compass-based learning. However, preferential use of the sun compass for learning requires an intact right HF. The data support the hypothesis that the left and right HF make different but complementary contributions toward avian spatial cognition.

  16. Medical pluralism and livestock health: ethnomedical and biomedical veterinary knowledge among East African agropastoralists.

    Human and animal health are deeply intertwined in livestock dependent areas. Livestock health contributes to food security and can influence human health through the transmission of zoonotic diseases. In low-income countries diagnosis and treatment of livestock diseases is often carried out by household members who draw upon both ethnoveterinary medicine (EVM) and contemporary veterinary biomedicine (VB). Expertise in these knowledge bases, along with their coexistence, informs treatment and thus ultimately impacts animal and human health. The aim of the current study was to determine how socio-cultural and ecological differences within and between two livestock-keeping populations, the Maasai of northern Tanzania and Koore of southwest Ethiopia, impact expertise in EVM and VB and coexistence of the two knowledge bases. An ethnoveterinary research project was conducted to examine dimensions of EVM and VB knowledge among the Maasai (N = 142 households) and the Koore (N = 100). Cultural consensus methods were used to quantify expertise and the level of agreement on EVM and VB knowledge. Ordinary least squares regression was used to model patterns of expertise and consensus across groups and to examine associations between knowledge and demographic/sociocultural attributes. Maasai and Koore informants displayed high consensus on EVM but only the Koore displayed consensus on VB knowledge. EVM expertise in the Koore varied across gender, herd size, and level of VB expertise. EVM expertise was highest in the Maasai but was only associated with age. The only factor associated with VB expertise was EVM expertise in the Koore. Variation in consensus and the correlates of expertise across the Maassi and the Koore are likely related to differences in the cultural transmission of EVM and VB knowledge. Transmission dynamics are established by the integration of livestock within the socioecological systems of the Maasai and Koore and culture historical experiences with livestock disease. Consideration of the nature and coexistence of EVM and VB provides insight into the capacity of groups to cope with disease outbreaks, pharmaceutical use patterns, and the development of community health interventions.

  17. High-resolution imaging of expertise reveals reliable object selectivity in the fusiform face area related to perceptual performance

    2012-01-01

    The fusiform face area (FFA) is a region of human cortex that responds selectively to faces, but whether it supports a more general function relevant for perceptual expertise is debated. Although both faces and objects of expertise engage many brain areas, the FFA remains the focus of the strongest modular claims and the clearest predictions about expertise. Functional MRI studies at standard-resolution (SR-fMRI) have found responses in the FFA for nonface objects of expertise, but high-resolution fMRI (HR-fMRI) in the FFA [Grill-Spector K, et al. (2006) Nat Neurosci 9:1177–1185] and neurophysiology in face patches in the monkey brain [Tsao DY, et al. (2006) Science 311:670–674] reveal no reliable selectivity for objects. It is thus possible that FFA responses to objects with SR-fMRI are a result of spatial blurring of responses from nonface-selective areas, potentially driven by attention to objects of expertise. Using HR-fMRI in two experiments, we provide evidence of reliable responses to cars in the FFA that correlate with behavioral car expertise. Effects of expertise in the FFA for nonface objects cannot be attributed to spatial blurring beyond the scale at which modular claims have been made, and within the lateral fusiform gyrus, they are restricted to a small area (200 mm2 on the right and 50 mm2 on the left) centered on the peak of face selectivity. Experience with a category may be sufficient to explain the spatially clustered face selectivity observed in this region. PMID:23027970

    Researchers have identified a component of the EEG that discriminates visual experts from novices. The marker indexes a comprehensive model of visual processing, and if it is apparent in physicians, it could be used to investigate the development and training of their visual expertise. The purpose of this study was to determine whether a neural marker of visual expertise-the enhanced N170 event-related potential-is apparent in the EEGs of physicians as they interpret diagnostic images. We conducted a controlled trial with 10 cardiologists and 9 pulmonologists. Each participant completed 520 trials of a standard visual processing task involving the rapid evaluation of EKGs and CXRs-indicating-lung-disease. Ostensibly, each participant is expert with one type of image and competent with the other. We collected behavioral data on the participants' expertise with EKGs and CXRs and electrophysiological data on the magnitude, latency, and scalp location of their N170 ERPs as they interpreted the two types of images. Cardiologists demonstrated significantly more expertise with EKGs than CXRs, and this was reflected in an increased amplitude of their N170 ERPs while reading EKGs compared to CXRs. Pulmonologists demonstrated equal expertise with both types of images, and this was reflected in equal N170 ERP amplitudes for EKGs and CXRs. The results suggest provisionally that visual expertise has a similar substrate in medical practice as it does in other domains that have been studied extensively. This provides support for applying a sophisticated body of literature to questions about training and assessment of visual expertise among physicians.

    Traumatic brain injuries have major socio-economic importance due to their frequency, high mortality and serious consequences. According to their nature the consequences of these injuries may be classified as neurological, psychiatric and esthetic. Various lesions of brain structures cause neurological consequences such as disturbance of motor functions, sensibility, coordination or involuntary movements, speech disturbances and other deviations, as well as epilepsy. Psychiatric consequences include cognitive deficit, emotional disturbances and behavior disturbances. CRIMINAL-LEGAL ASPECT OF TRAUMATIC BRAIN INJURIES AND LITIGATION: Criminal-legal aspect of traumatic brain injuries expertise understands the qualification of these injuries as mild, serious and qualified serious body injuries as well as the expertise about the mechanisms of their occurrence. Litigation expertise includes the estimation of pain, fear, diminished, i.e. lost vital activity and disability, esthetic marring, and psychological suffer based on the diminished general vital activity and esthetic marring. Evaluation of consequences of traumatic brain injuries should be performed only when it can be positively confirmed that they are permanent, i.e. at least one year after the injury. Expertise of these injuries is interdisciplinary. Among clinical doctors the most competent medical expert is the one who is in charge for diagnostics and injury treatment, with the recommendation to avoid, if possible, the doctor who conducted treatment. For the estimation of general vital activity, the neurological consequences, pain and esthetic marring expertise, the most competent doctors are neurosurgeon and neurologist. Psychological psychiatric consequences and fear expertise have to be performed by the psychiatrist. Specialists of forensic medicine contribute with knowledge of criminal low and legal expertise.

  1. Beyond perceptual expertise: revisiting the neural substrates of expert object recognition

    Harel, Assaf; Kravitz, Dwight; Baker, Chris I.

    2013-01-01

    Real-world expertise provides a valuable opportunity to understand how experience shapes human behavior and neural function. In the visual domain, the study of expert object recognition, such as in car enthusiasts or bird watchers, has produced a large, growing, and often-controversial literature. Here, we synthesize this literature, focusing primarily on results from functional brain imaging, and propose an interactive framework that incorporates the impact of high-level factors, such as attention and conceptual knowledge, in supporting expertise. This framework contrasts with the perceptual view of object expertise that has concentrated largely on stimulus-driven processing in visual cortex. One prominent version of this perceptual account has almost exclusively focused on the relation of expertise to face processing and, in terms of the neural substrates, has centered on face-selective cortical regions such as the Fusiform Face Area (FFA). We discuss the limitations of this face-centric approach as well as the more general perceptual view, and highlight that expert related activity is: (i) found throughout visual cortex, not just FFA, with a strong relationship between neural response and behavioral expertise even in the earliest stages of visual processing, (ii) found outside visual cortex in areas such as parietal and prefrontal cortices, and (iii) modulated by the attentional engagement of the observer suggesting that it is neither automatic nor driven solely by stimulus properties. These findings strongly support a framework in which object expertise emerges from extensive interactions within and between the visual system and other cognitive systems, resulting in widespread, distributed patterns of expertise-related activity across the entire cortex.

    Expertise is characterized by fast decision-making which is highly adaptive to new situations. Here we propose that athletes use a toolbox of heuristics which they develop on their route to expertise. The development of heuristics occurs within the context of the athletes' natural abilities, past experiences, developed skills, and situational context, but does not pertain to any of these factors separately. This is a novel approach because it integrates separate factors into a comprehensive heuristic description. The novelty of this approach lies within the integration of separate factors determining expertise into a comprehensive heuristic description. It is our contention that talent identification methods and talent development models should therefore be geared toward the assessment and development of specific heuristics. Specifically, in addition to identifying and developing separate natural abilities and skills as per usual, heuristics should be identified and developed. The application of heuristics to talent and expertise models can bring the field one step away from dichotomized models of nature and nurture toward a comprehensive approach to the route to expertise.

  5. Beyond Faces and Expertise: Facelike Holistic Processing of Nonface Objects in the Absence of Expertise.

    PubMed

    2016-02-01

    Holistic processing-the tendency to perceive objects as indecomposable wholes-has long been viewed as a process specific to faces or objects of expertise. Although current theories differ in what causes holistic processing, they share a fundamental constraint for its generalization: Nonface objects cannot elicit facelike holistic processing in the absence of expertise. Contrary to this prevailing view, here we show that line patterns with salient Gestalt information (i.e., connectedness, closure, and continuity between parts) can be processed as holistically as faces without any training. Moreover, weakening the saliency of Gestalt information in these patterns reduced holistic processing of them, which indicates that Gestalt information plays a crucial role in holistic processing. Therefore, holistic processing can be achieved not only via a top-down route based on expertise, but also via a bottom-up route relying merely on object-based information. The finding that facelike holistic processing can extend beyond the domains of faces and objects of expertise poses a challenge to current dominant theories. © The Author(s) 2015.

    2005-12-01

    Expertise consists of many different cognitive structures. Lemaire and Siegler (1995) have proposed a four-layered account of expertise from a strategies perspective: Experts have better strategies, tend to use strategies that are better overall more often, are better able to select the circumstances to which a strategy best applies, and are better able to execute a given strategy. Originally, this account came from work in simple, well-defined domains. We explored this account in the complex, ill-defined domain of platoon leadership. In Experiment 1A, we elicited free-text responses to leadership scenarios from novices, intermediates, and experts, finding expertise effects for strategy base rates and choice, but not for strategy existence or the number of strategies used. In Experiment 1B, we used a new group of experts to gather ratings of the execution accuracy of the responses in Experiment 1A and found expertise differences in the ability to execute the same strategies. We propose several elaborations to the original four-layered strategies account of expertise on the basis of these results.

    2006-01-01

    Today local, national and international ethics committees have become an effective means of social regulation in many European countries. Science itself is an important precondition for the development of bioethical knowledge and ethics expertise. Cultural, social, historical and religious preconditions can facilitate different forms and methods of ethics expertise in each country. Ukrainian ethics expertise has some methodological problems connected with its socio-cultural, historical, science and philosophy development particularities. In this context, clarification of some common legitimacies or methodological approaches to ethics committee (EC) phenomena such as globalization, scientization and the prioritization of an ethics paradigm are very important. On the other hand, elaborate study and critical analysis of international experience by Ukraine and other Eastern European countries will provide the integration of their local and national ethics expertises into a world bioethics ethos.

  10. The Roles of Intuition and Informants' Expertise in Children's Epistemic Trust.

    Lane, Jonathan D; Harris, Paul L

    2015-01-01

    This study examined how children's intuitions and informants' expertise influence children's trust in informants' claims. Three- to 8-year-olds (N = 192) watched videos in which experts (animal/biology experts or artifact/physics experts) made either intuitively plausible or counterintuitive claims about obscure animals or artifacts. Claims fell either within or beyond experts' domains of expertise. Children of all ages were more trusting of claims made by informants with relevant, as opposed to irrelevant, expertise. Children also showed greater acceptance of intuitive rather than counterintuitive claims, a differentiation that increased with age as they developed firmer intuitions about what can ordinarily happen. In summary, children's trust in testimony depends on whether informants have the relevant expertise as well as on children's own developing intuitions. © 2014 The Authors.

  11. Adults' and Children's Understanding of How Expertise Influences Learning.

    2018-01-01

    Adults and children use information about expertise to infer what a person is likely to know, but it is unclear whether they realize that expertise also has implications for learning. We explore adults' and children's understanding that expertise in a particular category supports learning about a closely related category. In four experiments, 5-year-olds and adults (n = 160) judged which of two people would be better at learning about a new category. When faced with an expert and a nonexpert, adults consistently indicated that expertise supports learning in a closely related category; however, children's judgments were inconsistent and were strongly influenced by the description of the nonexpert. The results suggest that although children understand what it means to be an expert, they may judge an individual's learning capacity based on different considerations than adults.

  12. [Consistency and Reliability of MDK Expertise Examining the Encoding in the German DRG System].

    Hospital inpatient stays are reimbursed on the basis of German diagnosis-related groups (G-DRG). The G-DRG classification system is based on complex coding guidelines. The Medical Review Board of the Statutory Health Insurance Funds (MDK) examines the encoding by hospitals and delivers individual expertises on behalf of the German statutory health insurance companies in cases in which irregularities are suspected. A study was conducted on the inter-rater reliability of the MDK expertises regarding the scope of the assessment. A representative sample of 212 MDK expertises was taken from a selected pool of 1 392 MDK expertises in May 2013. This representative sample underwent a double-examination by 2 independent MDK experts using a special software based on the 3MTM G-DRG Grouper 2013 of 3M Medica, Germany. The following items encoded by the hospitals were examined: DRG, principal diagnosis, secondary diagnoses, procedures and additional payments. It was analysed whether the results of MDK expertises were consistent, reliable and correct. 202 expertises were eligible for evaluation, containing a total of 254 questions regarding one or more of the 5 items encoded by hospitals. The double-examination by 2 independent MDK experts showed matching results in 187 questions (73.6%) meaning they had been examined consistently and correctly. 59 questions (23.2%) did not show matching results, nevertheless they had been examined correctly regarding the scope of the assessment. None of the principal diagnoses was significantly affected by inconsistent or wrong judgment. A representative sample of MDK expertises examining the DRG encoding by hospitals showed a very high percentage of correct examination by the MDK experts. Identical MDK expertises cannot be achieved in all cases due to the scope of the assessment. Further improvement and simplification of codes and coding guidelines are required to reduce the scope of assessment with regard to correct DRG encoding and its examination. © Georg Thieme Verlag KG Stuttgart · New York.

    To investigate patients' attitudes toward complementary and alternative medicine, the education nurses provided about complementary and alternative medicine for treating depression and to test whether such education mediates the effect of complementary and alternative medicine use and attitudes toward complementary and alternative medicine. Although we know that attitudes influence behaviour, very few studies simultaneously explore the relationship between attitudes, education and complementary and alternative medicine use. Survey. This study was conducted as part of a larger survey, using face-to-face survey interviews with 206 adult patients aged 50 years or over and hospitalised in conventional hospitals in Taiwan for treatment of depression. The attitudes toward complementary and alternative medicine and patient education about complementary and alternative medicine instruments were specially developed for the study. Participants expressed slightly favourable attitudes toward complementary and alternative medicine. Many participants (50%) expressed that they were willing to try any potential treatment for depression. They believed that complementary and alternative medicine helped them to feel better and to live a happier life. However, 66.5% of participants reported that they had inadequate knowledge of complementary and alternative medicine. Participants with a higher monthly income, longer depression duration and religious beliefs hold more positive attitudes toward complementary and alternative medicine. Most participants were not satisfied with the education they received about complementary and alternative medicine. Patient education about complementary and alternative medicine was found to be a mediator for the use of complementary and alternative medicine. Patient education from nurses may predict patients' attitudes toward complementary and alternative medicine. Continuing nursing education is needed to enable nurses to respond knowledgeably to concerns patients may have about complementary and alternative medicine and treatment options. This study highlights the potential role of patient education about complementary and alternative medicine as an effective way of adjusting patients' attitudes toward complementary and alternative medicine and to link both patients' preferences for complementary and alternative medicine and health professionals' concerns about the proper use of complementary and alternative medicine for depression management and adverse drug interactions.

    2012-12-01

    Whenever a geoscientific study area is not readily accessible, as is the case on the deep seafloor, it is difficult to apply traditional but effective methods of fieldwork, which often require physical presence of the observer. The Artificial Research Environment for Networked Analysis (ARENA), developed at GEOMAR | Helmholtz Centre for Ocean Research Kiel within the Cluster of Excellence "The Future Ocean", provides a backend solution to robotic research on the seafloor by means of an immersive simulation environment for marine research: A hemispherical screen of 6m diameter covering the entire lower hemisphere surrounds a group of up to four researchers at once. A variety of open source (e.g. Microsoft Research World Wide Telescope) and commercial software platforms allow the interaction with e.g. in-situ recorded video, vector maps, terrain, textured geometry, point cloud and volumetric data in four dimensions. Data can be put into a holistic, georeferenced context and viewed on scales stretching from centimeters to global. Several input devices from joysticks to gestures and vocalized commands allow interaction with the simulation, depending on individual preference. Annotations added to the dataset during the simulation session catalyze the following quantitative evaluation. Both the special simulator design, making data perception a group experience, and the ability to connect remote instances or scaled down versions of ARENA over the Internet are significant advantages over established immersive simulation environments.

    Wireless power, when coupled with miniaturized implantable electronics, has the potential to provide a solution to several challenges facing neuroscientists during basic and preclinical studies with freely behaving animals. The EnerCage system is one such solution as it allows for uninterrupted electrophysiology experiments over extended periods of time and vast experimental arenas, while eliminating the need for bulky battery payloads or tethering. It has a scalable array of overlapping planar spiral coils (PSCs) and three-axis magnetic sensors for focused wireless power transmission to devices on freely moving subjects. In this paper, we present the first fully functional EnerCage system, in which the number of PSC drivers and magnetic sensors was reduced to one-third of the number used in our previous design via multicoil coupling. The power transfer efficiency (PTE) has been improved to 5.6% at a 120 mm coupling distance and a 48.5 mm lateral misalignment (worst case) between the transmitter (Tx) array and receiver (Rx) coils. The new EnerCage system is equipped with an Ethernet backbone, further supporting its modular/scalable architecture, which, in turn, allows experimental arenas with arbitrary shapes and dimensions. A set of experiments on a freely behaving rat were conducted by continuously delivering 20 mW to the electronics in the animal headstage for more than one hour in a powered 3538 cm2 experimental area.

    Foraging groups of Formosan subterranean termites, Coptotermes formosanus Shiraki were tested for their relative humidity (RH) preference in a humidity gradient arena in the laboratory at a constant temperature of 26°C. Five RH levels (9%, 33%, 53%, 75%, and 98%) were maintained in the test arena comprising of a series of closed containers by using dry silica gel, saturated salt solutions, or distilled water alone. Termites gradually aggregated to the highest RH chamber in the arena. After 1 h, a significantly greater percentage of termites (≈46%) aggregated to the highest RH chamber (98%) than to the lower RH chambers (≤75%). After 12 h, > 97% of the termites aggregated to the 98% RH chamber. In survival tests, where termites were exposed to 15 combinatorial treatments of five RH levels (9%, 33%, 53%, 75%, and 98%) and three temperatures (20°C, 28°C, and 36°C) for a week, the survival was significantly influenced by RH, temperature, and their interaction. A significantly higher mortality was observed on termites exposed to ≤75% RH chambers than to 98% RH chamber at the three temperatures and significantly lower survival was found at 36°C than at 28°C or 20°C. The combination of temperature and RH plays an important role in the survival of C. formosanus.

    Effective interdisciplinary communication is important to achieve better quality in health care. The aims of this study were to compare conventional and complementary providers' experience of communication about complementary therapies and conventional medicine with their cancer patients, and to investigate how they experience interdisciplinary communication and cooperation. This study analyzed data from a self-administrated questionnaire. A total of 606 different health care providers, from four counties in Norway, completed the questionnaire. The survey was developed to describe aspects of the communication pattern among oncology doctors, nurses, family physicians and complementary therapists (acupuncturists, massage therapists and reflexologists/zone-therapists). Between-group differences were analyzed using chi-square, ANOVA and Fisher's exact tests. Significance level was defined as p < 0.05 without adjustment for multiple comparisons. Conventional providers and complementary therapists had different patterns of communication with their cancer patients regarding complementary therapies. While complementary therapists advised their patients to apply both complementary and conventional modalities, medical doctors were less supportive of their patients' use of complementary therapies. Of conventional providers, nurses expressed more positive attitudes toward complementary therapies. Opportunities to improve communication between conventional and complementary providers were most strongly supported by complementary providers and nurses; medical doctors were less supportive of such attempts. A number of doctors showed lack of respect for complementary therapists, but asked for more research, guidelines for complementary modalities and training in conventional medicine for complementary therapists. For better quality of care, greater communication about complementary therapy use is needed between cancer patients and their conventional and complementary providers. In addition, more communication between conventional and complementary providers is needed. Nurses may have a crucial role in facilitating communication, as they are positive toward complementary therapies and they have more direct communication with patients about their treatment preferences.

    2009-01-01

    While there is widespread interest in and admiration of individuals with exceptional talents, surprisingly little is known about the cognitive and neural mechanisms underpinning talent, and indeed how talent relates to expertise. Because many talents are first identified and nurtured in childhood, it can be difficult to determine whether talent is innate, can be acquired through extensive practice or can only be acquired in the presence of the developing brain. We sought to address some of these issues by studying healthy adults who acquired expertise in adulthood. We focused on the domain of memory and used licensed London taxi drivers as a model system. Taxi drivers have to learn the layout of 25 000 streets in London and the locations of thousands of places of interest, and pass stringent examinations in order to obtain an operating licence. Using neuropsychological assessment and structural and functional magnetic resonance imaging, we addressed a range of key questions: in the context of a fully developed brain and an average IQ, can people acquire expertise to an exceptional level; what are the neural signatures, both structural and functional, associated with the use of expertise; does expertise change the brain compared with unskilled control participants; does it confer any cognitive advantages, and similarly, does it come at a cost to other functions? By studying retired taxi drivers, we also consider what happens to their brains and behaviour when experts stop using their skill. Finally, we discuss how the expertise of taxi drivers might relate to the issue of talent and innate abilities. We suggest that exploring talent and expertise in this manner could have implications for education, rehabilitation of patients with cognitive impairments, understanding individual differences and possibly conditions such as autism where exceptional abilities can be a feature.

    Previous research into the effects of action video gaming on cognition has suggested that long term exposure to this type of game might lead to an enhancement of cognitive skills that transfer to non-gaming cognitive tasks. However, these results have been controversial. The aim of the current study was to test the presence of positive cognitive transfer from action video games to two cognitive tasks. More specifically, this study investigated the effects that participants' expertise and genre specialization have on cognitive improvements in one task unrelated to video gaming (a flanker task) and one related task (change detection task with both control and genre-specific images). This study was unique in three ways. Firstly, it analyzed a continuum of expertise levels, which has yet to be investigated in research into the cognitive benefits of video gaming. Secondly, it explored genre-specific skill developments on these tasks by comparing Action and Strategy video game players (VGPs). Thirdly, it used a very tight experiment design, including the experimenter being blind to expertise level and genre specialization of the participant. Ninety-two university students aged between 18 and 30 (M = 21.25) were recruited through opportunistic sampling and were grouped by video game specialization and expertise level. While the results of the flanker task were consistent with previous research (i.e., effect of congruence), there was no effect of expertise, and the action gamers failed to outperform the strategy gamers. Additionally, contrary to expectation, there was no interaction between genre specialization and image type in the change detection task, again demonstrating no expertise effect. The lack of effects for game specialization and expertise goes against previous research on the positive effects of action video gaming on other cognitive tasks. PMID:25506330

  16. Contributions of visual and embodied expertise to body perception.

    Reed, Catherine L; Nyberg, Andrew A; Grubb, Jefferson D

    2012-01-01

    Recent research has demonstrated that our perception of the human body differs from that of inanimate objects. This study investigated whether the visual perception of the human body differs from that of other animate bodies and, if so, whether that difference could be attributed to visual experience and/or embodied experience. To dissociate differential effects of these two types of expertise, inversion effects (recognition of inverted stimuli is slower and less accurate than recognition of upright stimuli) were compared for two types of bodies in postures that varied in typicality: humans in human postures (human-typical), humans in dog postures (human-atypical), dogs in dog postures (dog-typical), and dogs in human postures (dog-atypical). Inversion disrupts global configural processing. Relative changes in the size and presence of inversion effects reflect changes in visual processing. Both visual and embodiment expertise predict larger inversion effects for human over dog postures because we see humans more and we have experience producing human postures. However, our design that crosses body type and typicality leads to distinct predictions for visual and embodied experience. Visual expertise predicts an interaction between typicality and orientation: greater inversion effects should be found for typical over atypical postures regardless of body type. Alternatively, embodiment expertise predicts a body, typicality, and orientation interaction: larger inversion effects should be found for all human postures but only for atypical dog postures because humans can map their bodily experience onto these postures. Accuracy data supported embodiment expertise with the three-way interaction. However, response-time data supported contributions of visual expertise with larger inversion effects for typical over atypical postures. Thus, both types of expertise affect the visual perception of bodies.

    To describe the performance of a lifelong task-based questionnaire (TBQ) in estimating exposures compared with other approaches in the context of a case-control study. A sample of 93 subjects was randomly selected from a lung cancer case-control study corresponding to 497 jobs. For each job, exposure assessments for asbestos and polycyclic aromatic hydrocarbons (PAHs) were obtained by expertise (TBQ expertise) and by algorithm using the TBQ (TBQ algorithm) as well as by expert appraisals based on all available occupational data (REFERENCE expertise) considered to be the gold standard. Additionally, a Job Exposure Matrix (JEM)-based evaluation for asbestos was also obtained. On the 497 jobs, the various evaluations were contrasted using Cohen's κ coefficient of agreement. Additionally, on the total case-control population, the asbestos dose-response relationship based on the TBQ algorithm was compared with the JEM-based assessment. Regarding asbestos, the TBQ-exposure estimates agreed well with the REFERENCE estimate (TBQ expertise: level-weighted κ (lwk)=0.68; TBQ algorithm: lwk=0.61) but less so with the JEM estimate (TBQ expertise: lwk=0.31; TBQ algorithm: lwk=0.26). Regarding PAHs, the agreements between REFERENCE expertise and TBQ were less good (TBQ expertise: lwk=0.43; TBQ algorithm: lwk=0.36). In the case-control study analysis, the dose-response relationship between lung cancer and cumulative asbestos based on the JEM is less steep than with the TBQ-algorithm exposure assessment and statistically non-significant. Asbestos-exposure estimates based on the TBQ were consistent with the REFERENCE expertise and yielded a steeper dose-response relationship than the JEM. For PAHs, results were less clear.

    Expert knowledge is a valuable source of information with a wide range of research applications. Despite the recent advances in defining expert knowledge, little attention has been given to how to view expertise as a system of interacting contributory factors for quantifying an individual's expertise. We present a systems approach to expertise that accounts for many contributing factors and their inter-relationships and allows quantification of an individual's expertise. A Bayesian network (BN) was chosen for this purpose. For illustration, we focused on taxonomic expertise. The model structure was developed in consultation with taxonomists. The relative importance of the factors within the network was determined by a second set of taxonomists (supra-experts) who also provided validation of the model structure. Model performance was assessed by applying the model to hypothetical career states of taxonomists designed to incorporate known differences in career states for model testing. The resulting BN model consisted of 18 primary nodes feeding through one to three higher-order nodes before converging on the target node (Taxonomic Expert). There was strong consistency among node weights provided by the supra-experts for some nodes, but not others. The higher-order nodes, "Quality of work" and "Total productivity", had the greatest weights. Sensitivity analysis indicated that although some factors had stronger influence in the outer nodes of the network, there was relatively equal influence of the factors leading directly into the target node. Despite the differences in the node weights provided by our supra-experts, there was good agreement among assessments of our hypothetical experts that accurately reflected differences we had specified. This systems approach provides a way of assessing the overall level of expertise of individuals, accounting for multiple contributory factors, and their interactions. Our approach is adaptable to other situations where it is desirable to understand components of expertise.

    Patients are valuable sources of expertise for other patients in similar situations, but little is understood about the nature of this expertise. To address this knowledge gap, we investigated informational support as a mechanism for peers to help one another learn to cope with the breast cancer experience. We analyzed the types of problems discussed and recommendations offered by correspondents in three online breast cancer communities. Informational support was prevalent and directed towards problems in which correspondents were planning for future events or coping with emergent situations. Peers shared a wealth of patient expertise, including action strategies, recommended knowledge, suggested approaches, and information resources for dealing with problems. Our results highlight how peers are helping one another to learn. These findings bring insight to new support we could provide to patients for developing and sharing patient expertise, such as problem-based information organization and functionality for collaborative problem solving.

  20. Visual prediction and perceptual expertise

    PubMed Central

    Cheung, Olivia S.; Bar, Moshe

    2012-01-01

    Making accurate predictions about what may happen in the environment requires analogies between perceptual input and associations in memory. These elements of predictions are based on cortical representations, but little is known about how these processes can be enhanced by experience and training. On the other hand, studies on perceptual expertise have revealed that the acquisition of expertise leads to strengthened associative processing among features or objects, suggesting that predictions and expertise may be tightly connected. Here we review the behavioral and neural findings regarding the mechanisms involving prediction and expert processing, and highlight important possible overlaps between them. Future investigation should examine the relations among perception, memory and prediction skills as a function of expertise. The knowledge gained by this line of research will have implications for visual cognition research, and will advance our understanding of how the human brain can improve its ability to predict by learning from experience.

    Regions of the human temporal lobe show greater activation for speech than for other sounds. These differences may reflect intrinsically specialized domain-specific adaptations for processing speech, or they may be driven by the significant expertise we have in listening to the speech signal. To test the expertise hypothesis, we used a video-game-based paradigm that tacitly trained listeners to categorize acoustically complex, artificial non-linguistic sounds. Before and after training, we used functional MRI to measure how expertise with these sounds modulated temporal lobe activation. Participants’ ability to explicitly categorize the non-speech sounds predicted the change in pre- to post-training activation in speech-sensitive regions of the left posterior superior temporal sulcus, suggesting that emergent auditory expertise may help drive this functional regionalization. Thus, seemingly domain-specific patterns of neural activation in higher cortical regions may be driven in part by experience-based restructuring of high-dimensional perceptual space. PMID:19386919

    2005-08-01

    The relative importance of an internal sense of direction based on inertial cues and landmark piloting for small-scale navigation by White King pigeons (Columba livia) was investigated in an arena search task. Two groups of pigeons differed in whether they had access to visual cues outside the arena. In Experiment 1, pigeons were given experience with 2 different entrances and all pigeons transferred accurate searching to novel entrances. Explicit disorientation before entering did not affect accuracy. In Experiments 2-4, landmarks and inertial cues were put in conflict or tested 1 at a time. Pigeons tended to follow the landmarks in a conflict situation but could use an internal sense of direction to search when landmarks were unavailable. Copyright 2005 APA, all rights reserved.

  7. Geoscience Education Research: The Role of Collaborations with Education Researchers and Cognitive Scientists

    Geoscience Education Research aims to improve geoscience teaching and learning by understanding clearly the characteristics of geoscience expertise, the path from novice to expert, and the educational practices that can speed students along this path. In addition to expertise in geoscience and education, this research requires an understanding of learning -the domain of cognitive scientists. Beginning in 2002, a series of workshops and events focused on bringing together geoscientists, education researchers, and cognitive scientists to facilitate productive geoscience education research collaborations. These activities produced reports, papers, books, websites and a blog developing a research agenda for geoscience education research at a variety of scales: articulating the nature of geoscience expertise, and the overall importance of observation and a systems approach; focusing attention on geologic time, spatial skills, field work, and complex systems; and identifying key research questions in areas where new technology is changing methods in geoscience research and education. Cognitive scientists and education researchers played critical roles in developing this agenda. Where geoscientists ask questions that spring from their rich understanding of the discipline, cognitive scientists and education researchers ask questions from their experience with teaching and learning in a wide variety of disciplines and settings. These interactions tend to crystallize the questions of highest importance in addressing challenges of geoscience learning and to identify productive targets for collaborative research. Further, they serve as effective mechanisms for bringing research techniques and results from other fields into geoscience education. Working productively at the intersection of these fields requires teams of cognitive scientists, geoscientists, and education reserachers who share enough knowledge of all three domains to have a common articulation of the research problem, to make collaborative decisions, and to collectively problem solve. The development of this shared understanding is a primary result of the past decade of work. It has been developed through geoscience hosted events like the On the Cutting Edge emerging theme workshops and the Synthesis of Research on Thinking and Learning in the Geosciences project, complementary events in cognitive science and education that include geoscientists like the Gordon Conferences on Visualization in Science & Education or the Spatial Cognition conference series, and the interactions within and among geoscience education research projects like the Spatial Intelligence and Learning Center, the GARNET project, and many others. With this common ground in place, effective collaborations that bring together deep knowledge of psychology and brain function, of educational design and testing, and of time tested learning goals, teaching methods, and measures of success can flourish. A strong and accelerating research field has emerged that spans from work on basic cognitive skills important in geoscience, to studies of specific teaching strategies.

    2014-03-01

    The purpose of this paper is to make the link between expertise and biodiversity through the civil liability Law. Indeed, since Erika Case (Cour de Cassation, Crim. 25 septembre 2012), this Law recognised the ecological damage. This one is defined as an damage caused to Nature and especially Biodiversity. Thus, the expertise has to play a major role. In this paper, two roles are studied: first all all, the expertise allows to assess the damage of Biodiversity itself, to define and to prove it. Secondly, the expertise is an instrument which is very important for prescribing the measures of compensation, in kind or pecuniary compensation.

  15. Individual differences in chess expertise: a psychometric investigation.

    2007-03-01

    Starting from controversies over the role of general individual characteristics (especially intelligence) for the attainment of expert performance levels, a comprehensive psychometric investigation of individual differences in chess expertise is presented. A sample of 90 adult tournament chess players of varying playing strengths (1311-2387 ELO) was screened with tests on intelligence and personality variables; in addition, experience in chess play, tournament participation, and practice activities were assessed. Correlation and regression analyses revealed a clear-cut moderate relationship between general (and in particular numerical) intelligence and the participants' playing strengths, suggesting that expert chess play does not stand in isolation from superior mental abilities. The strongest predictor of the attained expertise level, however, was the participants' chess experience which highlights the relevance of long-term engagement for the development of expertise. Among all analysed personality dimensions, only domain-specific performance motivation and emotion expression control incrementally contributed to the prediction of playing strength. In total, measures of chess experience, current tournament activity, intelligence, and personality accounted for about 55% of variance in chess expertise. The present results suggest that individual differences in chess expertise are multifaceted and cannot be reduced to differences in domain experience.

    The purpose of this study was to investigate how attitude change is generated by the recipient's degree of attitude formation, evaluative-emotional elements contained in the persuasive messages, and source expertise as a peripheral cue in the persuasion context. Hypotheses based on the Attitude Formation Theory of Mizuhara (1982) and the Elaboration Likelihood Model of Petty and Cacioppo (1981, 1986) were examined. Eighty undergraduate students served as subjects in the experiment, the first stage of which involving manipulating the degree of attitude formation with respect to nuclear power development. Then, the experimenter presented persuasive messages with varying combinations of evaluative-emotional elements from a source with either high or low expertise on the subject. Results revealed a significant interaction effect on attitude change among attitude formation, persuasive message and the expertise of the message source. That is, high attitude formation subjects resisted evaluative-emotional persuasion from the high expertise source while low attitude formation subjects changed their attitude when exposed to the same persuasive message from a low expertise source. Results exceeded initial predictions based on the Attitude Formation Theory and the Elaboration Likelihood Model.

    2018-04-01

    The effect of art expertise on viewers' processing of titled visual artwork was examined. The study extended the research of Leder, Carbon, and Ripsas by explicitly selecting art novices and art experts. The study was designed to test assumptions about how expertise modulates context in the form of titles for artworks. Viewers rated a set of abstract paintings for liking and understanding. The type of title accompanying the artwork (descriptive or elaborative) was manipulated. Viewers were allotted as much time as they wished to view each artwork. For judgments of liking, novices and experts both liked artworks with elaborative titles better, with overall rated liking similar for both groups. For judgments of understanding, type of title had no effect on ratings for both novices and experts. However, experts' rated understanding was higher than novices, with experts making their decisions faster than novices. An analysis of viewers' art expertise revealed that expertise was correlated with understanding, but not liking. Overall, the results suggest that both novices and experts integrate title with visual image in similar manner. However, expertise differentially affected liking and understanding. The results differ from those obtained by Leder et al. The differences between studies are discussed.

  18. Development of professional expertise in optometry.

    2011-04-01

    Development of professional expertise is the gradual transition from novice to expert within a profession. Studies on expertise in the profession of optometry have never been published. However, many studies have been performed in other health professions (e.g., nursing, medicine, physical therapy, occupational therapy). This report is an overview of the development of professional expertise that will highlight some applications for optometry. A 5-level scale of professional expertise development, divided into 2 parts, is described. The first part is the progression of students during their professional studies (novice, intermediate, competent). The second part is the professional development occurring during the practice years (advanced, expert). Personal and collective efforts are required to foster the progression toward expertise. Great interest for the profession, motivation, and deliberate practice are individual attitudes that help this progression. The "optometric community of practice," by means of university (professional) training, continuing education, and collaboration between colleagues, also contributes to this process. Professional development is an integral part of the Optometric Oath. Each clinical case is a potential learning experience contributing to one's professional development. Optometrists' attitudes are predominant factors in the progression from one level to another. Copyright © 2011 American Optometric Association. Published by Elsevier Inc. All rights reserved.

    2018-07-01

    Quantitative assessment of surgical skills is an important aspect of surgical training; however, the proposed metrics are sometimes difficult to interpret and may not capture the stylistic characteristics that define expertise. This study proposes a methodology for evaluating the surgical skill, based on metrics associated with stylistic adjectives, and evaluates the ability of this method to differentiate expertise levels. We recruited subjects from different expertise levels to perform training tasks on a surgical simulator. A lexicon of contrasting adjective pairs, based on important skills for robotic surgery, inspired by the global evaluative assessment of robotic skills tool, was developed. To validate the use of stylistic adjectives for surgical skill assessment, posture videos of the subjects performing the task, as well as videos of the task were rated by crowd-workers. Metrics associated with each adjective were found using kinematic and physiological measurements through correlation with the crowd-sourced adjective assignment ratings. To evaluate the chosen metrics' ability in distinguishing expertise levels, two classifiers were trained and tested using these metrics. Crowd-assignment ratings for all adjectives were significantly correlated with expertise levels. The results indicate that naive Bayes classifier performs the best, with an accuracy of [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] when classifying into four, three, and two levels of expertise, respectively. The proposed method is effective at mapping understandable adjectives of expertise to the stylistic movements and physiological response of trainees.

    2013-04-01

    To compare the current status of global alcohol corporations with tobacco in terms of their role in global governance and to document the process by which this difference has been achieved and the consequences for alcohol control policy. Participant observation in the global political arena, review of industry materials (submissions, publications, conference presentations, websites) and review of published literature formed the basis for the current analysis. Recent events in the global political arena have highlighted the difference in perception of the alcohol and tobacco industries which has allowed alcohol corporations to participate in the global governance arena in a way in which tobacco has not been able. The transnational producers of alcohol have waged a sophisticated and successful campaign during the past three decades, including sponsorship of intergovernmental events, funding of educational initiatives, research, publications and sponsoring sporting and cultural events. A key aspect has been the framing of arguments to undermine perceptions of the extent of alcohol-related harms to health by promoting ideas of a balance of benefits and harms. An emphasis on the heaviest drinkers has been used to promote the erroneous idea that 'moderate' drinkers experience no harm and a goal of alcohol policy should be to ensure they are unaffected by interventions. This leads to highly targeted interventions towards the heaviest drinkers rather than effective regulation of the alcohol market. A sophisticated campaign by global alcohol corporations has promoted them as good corporate citizens and framed arguments with a focus on drinkers rather than the supply of alcohol. This has contributed to acceptance in the global governance arena dealing with policy development and implementation to an extent which is very different from tobacco. This approach, which obscures the contribution supply and marketing make to alcohol-related harm, has also contributed to failure by governments to adopt effective supply-side policies. © 2013 The Author, Addiction © 2013 Society for the Study of Addiction.

    There is a rapid increase in the percentage of elderly people in Europe. Consequently, the prevalence of age-related diseases will also significantly increase. Therefore, the main goal of MediHealth, an international research project, is to introduce a novel approach for the discovery of active agents of food plants from the Mediterranean diet and other global sources that promote healthy ageing. To achieve this goal, a series of plants from the Mediterranean diet and food plants from other origins are carefully selected and subjected to in silico, cell-based, in vivo (fly and mouse models), and metabolism analyses. Advanced analytical techniques complement the bio-evaluation process for the efficient isolation and identification of the bioactive plant constituents. Furthermore, pharmacological profiling of bioactive natural products, as well as the identification and synthesis of their metabolites, is carried out. Finally, optimization studies are performed in order to proceed to the development of innovative nutraceuticals, dietary supplements or herbal medicinal products. The project is based on an exchange of researchers between nine universities and four companies from European and non-European countries, exploiting the existing complementary multidisciplinary expertise. Herein, the unique and novel approach of this interdisciplinary project is presented.

    The medical certificate of no contraindication to the practice of sport, requires prudence during the exam preceding its writing for medicals and medico-legal reasons. It needs a careful questioning on important points relative to the risk of health problems during a sportive effort, especially to seek for the prodoms which can be found in 7 to 50% of cases. This questioning can sometimes be specific to certain specialities of sport. Actually, even if the concept of mass screening identify for sports people, amateurs or not, is still much debated, we can consider as a reasonable attitude, in consulting with the general medicine, to practice a careful cardiovascular examination and an ECG whose the interpretation, done with the expertise required, could help to detect about 60% of the possible lethal abnormalities to the physical effort. In case of doubt during the exam, the complementary investigations are needed in some cases (echocardiogram, stress testing, myocardial perfusion, electrophysiological endocavitary exploration). After that, the used advices can be given to the sportive candidate to minimize the risks. Despite these precautions, a subit death because of the effort can non totally be avoided. Finally, it must be remembered that the behaviour to have for kid and for elderly person involves certain specificities to know.

    2015-01-01

    The aim of this study was to compare experts to naïve practitioners in rating the beauty and the technical quality of a Tai Chi sequence observed in video-clips (of high and middle level performances). Our hypothesis are: i) movement evaluation will correlate with the level of skill expressed in the kinematics of the observed action but ii) only experts will be able to unravel the technical component from the aesthetic component of the observed action. The judgments delivered indicate that both expert and non-expert observers are able to discern a good from a mediocre performance; however, as expected, only experts discriminate the technical from the aesthetic component of the action evaluated and do this independently of the level of skill shown by the model (high or middle level performances). Furthermore, the judgments delivered were strongly related to the kinematic variables measured in the observed model, indicating that observers rely on specific movement kinematics (e.g. movement amplitude, jerk and duration) for action evaluation. These results provide evidence of the complementary functional role of visual and motor action representation in movement evaluation and underline the role of expertise in judging the aesthetic quality of movements.

    Chemical cross-linking mass spectrometry (XL-MS) provides protein structural information by identifying covalently linked proximal amino acid residues on protein surfaces. The information gained by this technique is complementary to other structural biology methods such as x-ray crystallography, NMR and cryo-electron microscopy[1]. The extension of traditional quantitative proteomics methods with chemical cross-linking can provide information on the structural dynamics of protein structures and protein complexes. The identification and quantitation of cross-linked peptides remains challenging for the general community, requiring specialized expertise ultimately limiting more widespread adoption of the technique. We describe a general method for targeted quantitative mass spectrometric analysis of cross-linked peptide pairs. We report the adaptation of the widely used, open source software package Skyline, for the analysis of quantitative XL-MS data as a means for data analysis and sharing of methods. We demonstrate the utility and robustness of the method with a cross-laboratory study and present data that is supported by and validates previously published data on quantified cross-linked peptide pairs. This advance provides an easy to use resource so that any lab with access to a LC-MS system capable of performing targeted quantitative analysis can quickly and accurately measure dynamic changes in protein structure and protein interactions.

    There is a critical need for improved diagnosis of tuberculosis in children, particularly in young children with intrathoracic disease as this represents the most common type of tuberculosis in children and the greatest diagnostic challenge. There is also a need for standardized clinical case definitions for the evaluation of diagnostics in prospective clinical research studies that include children in whom tuberculosis is suspected but not confirmed by culture of Mycobacterium tuberculosis. A panel representing a wide range of expertise and child tuberculosis research experience aimed to develop standardized clinical research case definitions for intrathoracic tuberculosis in children to enable harmonized evaluation of new tuberculosis diagnostic technologies in pediatric populations. Draft definitions and statements were proposed and circulated widely for feedback. An expert panel then considered each of the proposed definitions and statements relating to clinical definitions. Formal group consensus rules were established and consensus was reached for each statement. The definitions presented in this article are intended for use in clinical research to evaluate diagnostic assays and not for individual patient diagnosis or treatment decisions. A complementary article addresses methodological issues to consider for research of diagnostics in children with suspected tuberculosis. PMID:22448023

  8. Global health interdependence and the international physicians' movement.

    PubMed

    1990-08-01

    International Physicians for the Prevention of Nuclear War has had an impressive public impact in the 1980s, helping to shatter the myths of surviving and medically responding to a nuclear attack. The 1990s present a new challenge for the medical community in a different social and international context characterized by increasing global interdependence. Another view of physician activism is presented to complement advocacy for nuclear disarmament in the promotion of peace. A framework for analysis is provided by "fateful visions"--accepted policy views of prospective superpower relations--drawn from practitioners of foreign policy, international relations, and security affairs. A perceptual gap may exist between physicians who wish to address underlying ethical and public health concerns on security issues and policy practitioners who are accustomed to discussion within existing policy frames of reference that can be pragmatically used. A strategy is proposed for physicians to use their specialized training and skills to evaluate trends in global health interdependence. The international physicians' movement may contribute substantively to the formulation of policy by expanding and interpreting an increasingly complex database on interdependence, and by creating a dialogue with policy formulators based on mutual recognition of the value and legitimacy of each professions' expertise and complementary contributions to international security policy.

  9. Genome Editing: A New Approach to Human Therapeutics.

    PubMed

    Porteus, Matthew

    2016-01-01

    The ability to manipulate the genome with precise spatial and nucleotide resolution (genome editing) has been a powerful research tool. In the past decade, the tools and expertise for using genome editing in human somatic cells and pluripotent cells have increased to such an extent that the approach is now being developed widely as a strategy to treat human disease. The fundamental process depends on creating a site-specific DNA double-strand break (DSB) in the genome and then allowing the cell's endogenous DSB repair machinery to fix the break such that precise nucleotide changes are made to the DNA sequence. With the development and discovery of several different nuclease platforms and increasing knowledge of the parameters affecting different genome editing outcomes, genome editing frequencies now reach therapeutic relevance for a wide variety of diseases. Moreover, there is a series of complementary approaches to assessing the safety and toxicity of any genome editing process, irrespective of the underlying nuclease used. Finally, the development of genome editing has raised the issue of whether it should be used to engineer the human germline. Although such an approach could clearly prevent the birth of people with devastating and destructive genetic diseases, questions remain about whether human society is morally responsible enough to use this tool.

    This study examined the relationships between self-determination theory (SDT) and theory of planned behavior (TpB) applied to physical activity and exercise behavior (PA&E) in people with chronic pain. Two hundred and eleven adults with chronic musculoskeletal pain (28 males and 183 females, age range 18 to 82 years, mean age 43 years) were recruited from online support groups and clinic networks in the United States. Participants completed SDT measures relevant to PA&E on perceived autonomy support, autonomy, competence, and relatedness, as well as TpB measures relevant to PA&E on intention, attitudes, subjective norms, and perceived behavioral control. Correlational techniques and canonical correlation analysis were performed to examine the relationships and variance within and between theoretical dimensions. Overall, the SDT set accounted for 37% of the TpB variance and the TpB set accounted for 32% of the SDT set variance. The results indicate there are statistical similarities and differences between concepts in SDT and TpB models for PA&E. Using both empirical guidance and clinical expertise, researchers and practitioners should attempt to select and integrate non-redundant and complementary components from SDT, TpB, and other related health behavior theories.

    Following the growing interest in the further development of manikins to simulate human thermal behaviour more adequately, thermo-physiological human simulators have been developed by coupling a thermal sweating manikin with a thermo-physiology model. Despite their availability and obvious advantages, the number of studies involving these devices is only marginal, which plausibly results from the high complexity of the development and evaluation process and need of multi-disciplinary expertise. The aim of this paper is to present an integrated approach to develop, validate and operate such devices including technical challenges and limitations of thermo-physiological human simulators, their application and measurement protocol, strategy for setting test scenarios, and the comparison to standard methods and human studies including details which have not been published so far. A physical manikin controlled by a human thermoregulation model overcame the limitations of mathematical clothing models and provided a complementary method to investigate thermal interactions between the human body, protective clothing, and its environment. The opportunities of these devices include not only realistic assessment of protective clothing assemblies and equipment but also potential application in many research fields ranging from biometeorology, automotive industry, environmental engineering, and urban climate to clinical and safety applications.

  12. Is Beauty in the Eyes of the Beholder? Aesthetic Quality versus Technical Skill in Movement Evaluation of Tai Chi

    The aim of this study was to compare experts to naïve practitioners in rating the beauty and the technical quality of a Tai Chi sequence observed in video-clips (of high and middle level performances). Our hypothesis are: i) movement evaluation will correlate with the level of skill expressed in the kinematics of the observed action but ii) only experts will be able to unravel the technical component from the aesthetic component of the observed action. The judgments delivered indicate that both expert and non-expert observers are able to discern a good from a mediocre performance; however, as expected, only experts discriminate the technical from the aesthetic component of the action evaluated and do this independently of the level of skill shown by the model (high or middle level performances). Furthermore, the judgments delivered were strongly related to the kinematic variables measured in the observed model, indicating that observers rely on specific movement kinematics (e.g. movement amplitude, jerk and duration) for action evaluation. These results provide evidence of the complementary functional role of visual and motor action representation in movement evaluation and underline the role of expertise in judging the aesthetic quality of movements.

    Currently, diagnosis of skin diseases is based primarily on the visual pattern recognition skills and expertise of the physician observing the lesion. Even though dermatologists are trained to recognize patterns of morphology, it is still a subjective visual assessment. Tools for automated pattern recognition can provide objective information to support clinical decision-making. Noninvasive skin imaging techniques provide complementary information to the clinician. In recent years, optical coherence tomography (OCT) has become a powerful skin imaging technique. According to specific functional needs, skin architecture varies across different parts of the body, as do the textural characteristics in OCT images. There is, therefore, a critical need to systematically analyze OCT images from different body sites, to identify their significant qualitative and quantitative differences. Sixty-three optical and textural features extracted from OCT images of healthy and diseased skin are analyzed and, in conjunction with decision-theoretic approaches, used to create computational models of the diseases. We demonstrate that these models provide objective information to the clinician to assist in the diagnosis of abnormalities of cutaneous microstructure, and hence, aid in the determination of treatment. Specifically, we demonstrate the performance of this methodology on differentiating basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) from healthy tissue.

  20. Using Network-Based Language Analysis to Bridge Expertise and Cultivate Sensitivity to Differentiated Language Use in Interdisciplinary Geoscience Research

    On interdisciplinary teams, expertise is varied, as is evidenced by differences in team members' language use. Developing strategies to combine that expertise and bridge differentiated language practices is especially difficult between geoscience subdisciplines as researchers assume they use a shared language—vocabulary, jargon, codes, linguistic styles. In our paper, we discuss a network-based approach used to identify varied expertise and language practices between geoscientists (n=29) on a NSF team funded to study how deep and surface Earth processes worked together to give rise to the Great Oxygenation Event. We describe how we modeled the team's expertise from a language corpus consisting of 220 oxygen-related terms frequently used by team members and then compared their understanding of the terms to develop interventions to bridge the team's expertise. Corpus terms were identified via team member interviews, observations of members' interactions at research meetings, and discourse analysis of members' publications. Comparisons of members' language use were based on a Likert scale survey that asked members to assess how they understood a term; how frequently they used a term; and whether they conceptualized a term as an object or process. Rather than use our method as a communication audit tool (Zwijze-Koning & de Jong, 2015), teams can proactively use it in a project's early stages to assess the contours of the team's differentiated expertise and show where specialized knowledge resides in the team, where latent or non-obvious expertise exists, where expertise overlaps, and where gaps are in the team's knowledge. With this information, teams can make evidence based recommendations to forward their work such as allocating resources; identifying and empowering members to serve as connectors and lead cross-functional project initiatives; and developing strategies to avoid communication barriers. The method also generates models for teaching language sensitivity to subdisciplinary colleagues by making visible the nuanced ways they use language to organize and communicate their research. Ultimately, understanding the impact of differentiated language use is an unmet need in Earth science research, and our method offers a unique way to visualize and understand how such use impacts team communication.
