Toward a Script Theory of Guidance in Computer-Supported Collaborative Learning

PubMed Central

Fischer, Frank; Kollar, Ingo; Stegmann, Karsten; Wecker, Christof

2013-01-01

This article presents an outline of a script theory of guidance for computer-supported collaborative learning (CSCL). With its 4 types of components of internal and external scripts (play, scene, role, and scriptlet) and 7 principles, this theory addresses the question of how CSCL practices are shaped by dynamically reconfigured internal collaboration scripts of the participating learners. Furthermore, it explains how internal collaboration scripts develop through participation in CSCL practices. It emphasizes the importance of active application of subject matter knowledge in CSCL practices, and it prioritizes transactive over nontransactive forms of knowledge application in order to facilitate learning. Further, the theory explains how external collaboration scripts modify CSCL practices and how they influence the development of internal collaboration scripts. The principles specify an optimal scaffolding level for external collaboration scripts and allow for the formulation of hypotheses about the fading of external collaboration scripts. Finally, the article points toward conceptual challenges and future research questions. PMID:23378679

Shaping effective communication skills and therapeutic relationships at work: the foundation of collaboration.

PubMed

Grover, Susan M

2005-04-01

Effective communication is essential to practice and can result in improved interpersonal relationships at the workplace. Effective communication is shaped by basic techniques such as open-ended questions, listening, empathy, and assertiveness. However, the relationship between effective communication and successful interpersonal relationships is affected by intervening variables. The variables of gender, generation, context, collegiality, cooperation, self-disclosure, and reciprocity can impede or enhance the outcome of quality communication. It is essential for occupational health nurses to qualitatively assess the degree to which each of these concepts affects communication and, in turn, relationships at work.

Global Health Warning: Definitions Wield Power Comment on "Navigating Between Stealth Advocacy and Unconscious Dogmatism: The Challenge of Researching the Norms, Politics and Power of Global Health".

Gorik Ooms recently made a strong case for considering the centrality of normative premises to analyzing and understanding the underappreciated importance of the nexus of politics, power and process in global health. This critical commentary raises serious questions for the practice and study of global health and global health governance. First and foremost, this commentary underlines the importance of the question of what is global health, and why as well as how does this definition matter? This refocuses discussion on the importance of definitions and how they wield power. It also re-affirms the necessity of a deeper analysis and understanding of power and how it affects and shapes the practice of global health. © 2016 by Kerman University of Medical Sciences.

Maternity and modernity: Soviet women teachers and the contradictions of Stalinism.

PubMed

Ewing, E Thomas

2010-01-01

This article explores how Soviet political identities were shaped by maternal concerns and how mothers' practices were shaped by the professional obligations of teaching in the Stalinist 1930s. Exploring an occupation that became more female as it became more modern, a professional identity that denied or constrained female sexuality, a calling devoted to children that left little time for motherhood, and a social role that assigned the task of socialization to women who did not enjoy full civic rights, this study examines the ways that Stalinist mother teachers assumed a distinct identity through their practices at school and in the family. Identifying specific moments where these questions became public focuses attention on maternity and modernity in ways that illustrate how fully Stalinist repression penetrated into society and how the Soviet people perceived, accepted, challenged, or otherwise mediated the contradictory nature of these political forces.

Student questions in urban middle school science communities of practice

NASA Astrophysics Data System (ADS)

Groome, Meghan

This dissertation examines student questions within three Communities of Practice (CoP), all urban middle school science environments. The study analyzed student questions from a sociocultural perspective and used ethnographic research techniques to detail how the CoP's shaped questions in the classroom. In the first study, two case study girls attempted to navigate questioning events that required them to negotiation participation. Their access to participation was blocked by participation frameworks that elevated some students as "gatekeepers" while suppressing the participation of others. The next two studies detail the introduction of written questioning opportunities, one into a public middle school classroom and the other into an informal classroom. In both studies, students responded to the interventions differently, most notable the adoption of the opportunity by female students who do not participate orally. Dissertation-wide findings indicate all students were able to ask questions, but varied in level of cognitive complexity, and the diagnostic interventions were able to identify students who were not known to be "target students", students who asked a high number of questions and were considered "interested in science". Some students' roles were as "gatekeepers" to participation of their peers. Two out of three teachers in the studies reported major shifts in their teaching practice due to the focus on questions and the methods used here have been found to be effective in producing educational research as well as supporting high-need classrooms in prior research. In conclusion, these studies indicate that social factors, including participation frameworks, gender dynamics, and the availability of alternative participation methods, play an important role in how students ask science-related questions. It is recommended that researchers continue to examine social factors that reduce student questions and modify their teaching strategies to facilitate questioning. This data should be shared with teachers and teacher educators to inform them how to increase and use student questions as well as alternate participation methods that strive for "science for all". Future research should focus on how students act as "gatekeepers" for the participation and potential ways to shift underrepresented students into the STEM pipeline.

Abstract Objective  To combine insights from multiple disciplines into a set of questions that can be used to investigate contextual factors affecting health decision making. Background  Decision‐making processes and outcomes may be shaped by a range of non‐medical or ‘contextual’ factors particular to an individual including social, economic, political, geographical and institutional conditions. Research concerning contextual factors occurs across many disciplines and theoretical domains, but few conceptual tools have attempted to integrate and translate this wide‐ranging research for health decision‐making purposes. Methods  To formulate this tool we employed an iterative, collaborative process of scenario development and question generation. Five hypothetical health decision‐making scenarios (preventative, screening, curative, supportive and palliative) were developed and used to generate a set of exploratory questions that aim to highlight potential contextual factors across a range of health decisions. Findings  We present an exploratory tool consisting of questions organized into four thematic domains – Bodies, Technologies, Place and Work (BTPW) – articulating wide‐ranging contextual factors relevant to health decision making. The BTPW tool encompasses health‐related scholarship and research from a range of disciplines pertinent to health decision making, and identifies concrete points of intersection between its four thematic domains. Examples of the practical application of the questions are also provided. Conclusions  These exploratory questions provide an interdisciplinary toolkit for identifying the complex contextual factors affecting decision making. The set of questions comprised by the BTPW tool may be applied wholly or partially in the context of clinical practice, policy development and health‐related research. PMID:21029277

Medical students' perceptions of general practice as a career; a phenomenological study using socialisation theory.

PubMed

Reid, Katherine; Alberti, Hugh

2018-04-23

The ageing population and push to community care has significantly increased the workload of General Practitioners (GPs) in the UK and internationally. In an attempt to tackle this, NHS England has promised 5000 more GPs by 2020/21; however, recruitment is in crisis with GP training posts remaining unfilled. Little research has been carried out to assess the fundamental questions of what medical students' perceptions of General Practice are and what shapes their perceptions at medical school. We aimed to explore medical students' conceptualisations of being a GP and specifically the role of the medical school in shaping their perceptions. Two focus groups of year one and year four medical students were undertaken using an interpretive phenomenological approach. Our study has revealed that medical students perceive General Practice to lack prestige and challenge. These perceptions come, at least in part, from a process of socialisation within medical school, whereby medical students internalise and adopt their role models' perceptions and values, and the values portrayed by the hidden curriculum in their medical school culture. Perceived external pressures to pursue a career in General Practice can have a negative influence and medical schools should be made aware of this.

Shape Comparison Between 0.4–2.0 and 20–60 lm Cement Particles

DOE Office of Scientific and Technical Information (OSTI.GOV)

Holzer, L.; Flatt, R; Erdogan, S

Portland cement powder, ground from much larger clinker particles, has a particle size distribution from about 0.1 to 100 {micro}m. An important question is then: does particle shape depend on particle size? For the same cement, X-ray computed tomography has been used to examine the 3-D shape of particles in the 20-60 {micro}m sieve range, and focused ion beam nanotomography has been used to examine the 3-D shape of cement particles found in the 0.4-2.0 {micro}m sieve range. By comparing various kinds of computed particle shape data for each size class, the conclusion is made that, within experimental uncertainty, bothmore » size classes are prolate, but the smaller size class particles, 0.4-2.0 {micro}m, tend to be somewhat more prolate than the 20-60 {micro}m size class. The practical effect of this shape difference on the set-point was assessed using the Virtual Cement and Concrete Testing Laboratory to simulate the hydration of five cement powders. Results indicate that nonspherical aspect ratio is more important in determining the set-point than are the actual shape details.« less

1982-04-01

An evacuated tube concentrator which achieves respectable high temperature performance (100 C to 300 C) was developed. The design concept utilizes nonimaging CPC type concentration integrated into each tube by shaping the outer glass vacuum envelope. The detailed design, prototype fabrication and preliminary test measurements are reviewed. In addition the results of this first study specifically devoted to engineering development questions related to practical applications of this collector concept are summarized. Questions having to do with the deployment of medium to large area arrays, optimizations of the manifolding of individual tube panels, selected near term applications (with an emphasis on residential cooling based on Rankine driven chillers) and long term performance projections are addressed.

Modeling Cryotherapy Ice Ball Dimensions and Isotherms in a Novel Gel-based Model to Determine Optimal Cryo-needle Configurations and Settings for Potential Use in Clinical Practice

Objective To gain a better understanding of ice ball dimensions and temperature isotherms relevant for cell kill when using combinations of cryo-needles we set out to answer 4 questions: (1) what type of cryo-needle? (2) how many needles? (3) best spatial configuration? and (4) correct duty cycle percentage? Methods We conducted laboratory experiments to monitor ice ball dimensions and create multi-needle planar isotherm maps for 17G and 10G cryo-needles using a novel multi-needle thermocouple fixture within gel at body temperature. We tested configurations of 1-4 cryo-needles at duty cycles of 20%-100% with 1-2.5 cm spacing. Results Analysis of various combinations shows that a central core of ≤−40°C develops at a distance of ~1 cm around the cryo-needles. Temperature increases linearly from this point to the ice ball leading edge (0°C), which is a further ≈1 cm away. Thus, the −40°C isotherm is approximately 1 cm inside the leading edge of the ice ball. The optimum distance between cryo-needles was 1.5-2 cm, at duty cycle settings of 70%-100%. At distances further apart or with lower duty cycle settings, ice balls either had a central core >−40°C or had an hourglass shape. Conclusion In answer to questions 1-3, tumor length, diameter, and shape will ultimately determine the number of needles and their configuration. However, we propose a conservative distance for cryo-needle placement between 1 and 1.5 cm should be adopted for clinical practice. In answer to question 4, using low duty cycle settings runs the risk of incomplete −40°C isotherm coverage of the tumor, and thus in routine practice we suggest that settings of 70%-100% are most appropriate.

2017-04-01

The purpose of this study was to investigate the various roles that early elementary teachers adopt when questioning, to scaffold dialogic interaction and students' cognitive responses for argumentative practices over time. Teacher questioning is a pivotal contributing factor that shapes the role teachers play in promoting dialogic interaction in argumentative practice and that different roles serve different functions for promoting students' conceptual understanding. The multiple-case study was designed as a follow-up study after a 4-year professional development program that emphasized an argument-based inquiry approach. Data sources included 30 lessons focusing on whole class discussion from three early elementary teachers' classes. Data were analyzed through two approaches: (1) constant comparative method and (2) enumerative approach. This study conceptualized four critical roles of teacher questioning—dispenser, moderator, coach, and participant—in light of the ownership of ideas and activities. The findings revealed two salient changes in teachers' use of questions and the relationships between teachers' question-asking and students' cognitive responses: (1) teachers increasingly used multiple roles in establishing argumentative discourse as they persistently implemented an argument-based inquiry approach, and (2) as teachers used multiple roles in establishing patterns of questioning and framing classroom interactions, higher levels of student cognitive responses were promoted. This study suggests that an essential component of teacher professional development should include the study of the various roles that teachers can play when questioning for establishing dialogic interaction in argumentation and that this development should consist of ongoing training with systematic support.

"Women...mourn and men carry on": African women storying mourning practices: a South African example.

African mourning of loss of lives in South Africa has been shaped by discursive practices of both traditional African cultures and the sociopolitical developments under apartheid and in post-apartheid South Africa. This article reports on changes in mourning practices on the basis of a literature review and uses a collection of examples to highlight the navigation of some cultural and gendered issues relating to mourning, against the backdrop of the everyday experiences of loss of life in South Africa due to violence and HIV/AIDS. The article draws on African womanist and feminist scholarship and focuses on the intersections between cultural and gender practices of bereavement in the lives of professional urban African women. The authors argue for the use of positioning theory and witnessing practices to honor and story the ongoing struggle of African women as these women take different agentic positions by accepting, questioning, resisting, and/or changing cultural mourning practices while they compassionately witness the self and others in the narratives they live.

Low Vision Rehabilitation, Age-Related Vision Loss, and Risk: A Critical Interpretive Synthesis

Purpose: Given the centrality of risk in geriatric rehabilitation, it is critically important to attend to how conceptualizations of risk shape research, policies, and rehabilitation practices. This paper presents a critical interpretive synthesis (CIS) of literature addressing risk and low vision rehabilitation for older adults with age-related vision loss (ARVL) to identify key guiding assumptions regarding risk and discuss implications for what gets attended to, and not attended to, within research and rehabilitation. Design and Methods: This CIS combined guidelines proposed by Dixon-Woods and colleagues (2006—Conducting a critical interpretive synthesis of the literature on access to healthcare by vulnerable groups. BMC Medical Research Methodology, 6, 35) and Alvesson and Sandberg (2011—Generating research questions through problematization. Academy of Management Review, 36, 247–271; 2013—Constructing research questions: Doing interesting research. London: Sage). The iterative review process involved 3 steps: literature search and selection, data extraction, and syntheses to identify boundary assumptions. The dataset included 83 research and practice description articles. Results: Older adults with ARVL were constructed as “at risk” for various adverse outcomes, particularly dependency and self-harm, and as posing risks to others. An epidemiological approach to risk based in assumptions aligned with a technico-scientific perspective was dominant, with risk conceptualized as an embodied, individual-level phenomenon that is to be determined and managed through objective screening and expert monitoring. Implications: Key concerns include a lack of: attention to the tensions created when rehabilitation research and practice attempt to promote independence while simultaneously reducing risk, incorporation of aging adults’ perspectives on risk, and analysis of environmental factors that shape risks. Research that starts by valuing older adults’ experiences and attends to context can inform rehabilitation practices that support health-promoting, risk-taking, and facilitate collaborative approaches to risk management.

2011-12-01

This paper explains the concept of empathic leadership in the setting of fundamental organisational changes. It deals with the question of how you can establish a culture of leadership, which motivates employees positively and enthuses them for the upcoming changes. It discusses the basics of empathic leadership and considers the question of how handling of emotions influences change processes and how different management styles can be used supportively during changes. With the help of a practical example the different phases of change are presented from a management point of view. Thereby the theory of different levels of employee motivation is explained inter alia. The article shows that empathic leadership also has a lasting economic effect. This can be seen particularly in the power of motivation for change, in addition to recruitment and long-term employee retention.

Productive whole-class discussions: A qualitative analysis of peer leader behaviors in general chemistry

NASA Astrophysics Data System (ADS)

Eckart, Teresa Mcclain

The intention of this research was to describe behaviors and characteristics of General Chemistry I peer leaders using a pedagogical reform method referred to as Peer-led Guided Inquiry (PLGI), and to discuss the ways in which these peer leaders created productive whole-class discussions. This reform technique engaged students to work on guided inquiry activities while working cooperatively in small groups, led by undergraduate peer leaders. These sessions were video recorded and transcribed. The data was evaluated using grounded theory methods of analysis. This study examined the dialog between students and peer leaders, paying specific attention to question types and observed patterns of interactions. The research took shape by examining the kinds of questions asked by peer leaders and the purposes these questions served. In addition to looking at questions, different kinds of behaviors displayed by peer leaders during their small group sessions were also observed. A close examination of peer leader questions and behaviors aided in developing an answer to the overall research question regarding what factors are associated with productive whole-class discussions. Five major categories of peer leader behaviors evolved from the data and provided a means to compare and contrast productive whole-class discussions. While no category single-handedly determined if a discussion was good or bad, there was a tendency for peer leaders who exhibited positive traits in at least three of the following categories to have consistently better whole-class discussions: Procedural Practices, Supervisory Qualities, Questioning Techniques, Feedback/Responses, and Interpersonal Skills. Furthermore, each of the major categories is tied directly to Interpersonal, Communication, and Leadership skills and their interactions with each other. This study also addressed applications that each of these categories has on instructional practices and their need in peer leader training. In addition, a scale was developed for rating the relative effectiveness of whole-class discussions in terms of student participation. This study provides a tool for measuring productive whole-class discussions, as well as practical applications for peer leader (or teacher) training.

Seeking trust and transcendence: sexual risk-taking among Vietnamese youth.

PubMed

Gammeltoft, Tine

2002-08-01

This paper contends that sexuality research has paid far too limited attention to the phenomenology of sexual experience, thus failing to recognize the importance of embodied sensory experience for sexual perceptions and practices in general and for sexual risk-taking in particular. In order to comprehend the cultural rationales of sexual risk-taking among urban Vietnamese youth, the author presents an analysis which combines a detailed attention to the phenomenology of sexual experience with a social analysis of the wider socio-economic contexts within which sexual practices are embedded. It is demonstrated that the sexual encounters of Vietnamese youth involve much more than strivings for intimacy and pleasure: at stake are also fundamental questions of the moral integrity of the self and the socio-political shaping of intimate relations. Moreover, obstacles to safer sex stem not only from individual choices or intimate interpersonal interactions, but also from larger systems of moral meaning and social constraint. While the acknowledgement of individual capacities for action in the sexual sphere is important, it is equally important to recognize the responsibility of communities and political systems for the shaping of sexual interactions. Current limitations in the understanding of sexual experience and practice have consequences which seriously affect health interventions and education programmes targeting high-risk sexual behaviour. In order to develop more appropriate sexual health interventions, cultural transformations at the levels of both individual practice and societal organization are needed.

History of Neuropsychology Through Epilepsy Eyes

PubMed Central

Loring, David W.

2010-01-01

In the 19th century, Hughlings Jackson relied on clinical history, seizure semiology, and the neurologic examination as methods for seizure localization to inform the first epilepsy surgeries. In the 20th century, psychological and neuropsychological tests were first employed as both diagnostic and prognostic measures. The contemporary practice of epilepsy evaluation and management includes neuropsychology as a critical component of epilepsy care and research, and epilepsy and neuropsychology have enjoyed a very special and synergistic relationship. This paper reviews how epilepsy has shaped the practice of neuropsychology as a clinical service by asking critical questions that only neuropsychologists were in a position to answer, and how clinical care of epilepsy patients has been significantly improved based on neuropsychology's unique contributions.

2018-06-20

Drawing on fieldwork in the postsocialist Czech Republic, we explore the transformative processes of biomedicalization, both within and in relation to complementary and alternative medicine (CAM). We argue that it would be simplistic to understand evidence of these processes in CAM as a sign that CAM has fallen prey to biomedicine. Instead, we show how particular CAM practices play a groundbreaking role in shaping developments in contemporary health care. In this respect, we question the utility of the concept of biomedicalization, arguing that it reduces the transformative processes to aspects of biomedicine.

ABSTRACT Early years science education is not science, but a curricular construction designed to induct young children into a range of ideas and practices related to the natural world. While inquiry-based learning is an important approach to this, it is not of itself unique to science and there are a range of logico-mathematical constructions that come closer to the essence of science. In this paper we discuss just three: empirical question-asking, transgressive play, and good thinking. The challenge, of course is to induct early years practitioners to a different way of shaping early science. PMID:28392619

As molecular phylogeny increasingly shapes our understanding of organismal relationships, no molecule has been applied to more questions than have ribosomal RNAs. We review this role of the rRNAs and some of the insights that have been gained from them. We also offer some of the practical considerations in extracting the phylogenetic information from the sequences. Finally, we stress the importance of comparing results from multiple molecules, both as a method for testing the overall reliability of the organismal phylogeny and as a method for more broadly exploring the history of the genome.

Creative Processes in the Shaping of a Musical Interpretation: A Study of Nine Professional Musicians.

Héroux, Isabelle

2018-01-01

Various studies have been conducted to understand the role of mental representation when musicians practice or perform music (Lehman and Ericsson, 1997; Sloboda, 2005) and the work steps required for a musician to prepare a concert (Chaffin et al., 2003). More recent studies examine creativity in the shaping of a musical interpretation (Lisboa et al., 2011; Payne, 2016; Barros et al., 2017; Wise et al., 2017). However, none of these studies answers the following questions: Why do expert musicians working from the same score create different musical interpretations? During individual practice sessions, what happens that allows each musician to produce significantly different interpretive results? To answer these questions, we instructed nine expert musicians to record their individual practice sessions, verbalize their actions and thoughts, and answer a self-reflection questionnaire. A third-party observer also described what happened during the practice sessions. We conducted interviews in order to gather additional information about the contents of the individual practice sessions; the musicians' usual work habits; and their beliefs, values, and ideas regarding the role of the musician in the creative process. Based on the methodology of Analyse par théorisation ancrée (Paillé, 1994), we were able to take into account a diverse data set and identify aspects of the creative process that were specific to each individual as well as elements that all musicians shared. We found that the context in which the creative process takes place-the musician (e.g., his or her values and knowledge); the musical work (e.g., style, technical aspects, etc.); and the external constraints (e.g., deadlines, public expectations, etc.)-impacted the strategies used. The participants used reflection, extramusical supports, emotions, body reactions, intuition, and other tools to generate new musical ideas and evaluate the accuracy of their musical interpretations. We identified elements related to those already discussed in the literature, including the creative process as an alternation between divergent and convergent thinking (Guilford, 1950), creative associations (Lubart, 2015), and artistic appropriation (Héroux and Fortier, 2014; Héroux, 2016).

We identified elements related to those already discussed in the literature, including the creative process as an alternation between divergent and convergent thinking (Guilford, 1950), creative associations (Lubart, 2015), and artistic appropriation (Héroux and Fortier, 2014; Héroux, 2016).

This design experiment aimed to answer the question of how to mediate the practices of authentic science inquiries in primary education. An instructional approach based on activity theory was designed and carried out with multi-age students in a small village school. An open-ended learning task was offered to the older students. Their task was to design and implement instruction about the Ice Age to their younger fellows. The objective was collaborative learning among students, the teacher, and outside domain experts. Mobile phones and GPS technologies were applied as the main technological mediators in the learning process. Technology provided an opportunity to expand the learning environment outside the classroom, including the natural environment. Empirically, the goal was to answer the following questions: What kind of learning project emerged? How did the students' knowledge develop? What kinds of science learning processes, activities, and practices were represented? Multiple and parallel data were collected to achieve this aim. The data analysis revealed that the learning project both challenged the students to develop explanations for the phenomena and generated high quality conceptual and physical models in question. During the learning project, the roles of the community members were shaped, mixed, and integrated. The teacher also repeatedly evaluated and adjusted her behavior. The confidence of the learners in their abilities raised the quality of their learning outcomes. The findings showed that this instructional approach can not only mediate the kind of authentic practices that scientists apply but also make learning more holistic than it has been. Thus, it can be concluded that nature of the task, the tool-integrated collaborative inquiries in the natural environment, and the multiage setting can make learning whole.

Typhoid Fever in nineteenth-century Colombia: between medical geography and bacteriology.

García, Mónica

2014-01-01

This paper analyses how the Colombian medical elites made sense of typhoid fever before and during the inception of bacteriological ideas and practices in the second half of the nineteenth century. Assuming that the identity of typhoid fever has to be understood within the broader concerns of the medical community in question, I show how doctors first identified Bogotá's epidemics as typhoid fever during the 1850s, and how they also attached specificity to the fever amongst other continuous fevers, such as its European and North American counterparts. I also found that, in contrast with the discussions amongst their colleagues from other countries, debates about typhoid fever in 1860-70 among doctors in Colombia were framed within the medico-geographical scheme and strongly shaped by the fear of typhoid fever appearing alongside 'paludic' fevers in the highlands. By arguing in medico-geographical and clinical terms that typhoid fever had specificity in Colombia, and by denying the medico-geographical law of antagonism between typhoid and paludic fevers proposed by the Frenchman Charles Boudin, Colombian doctors managed to question European knowledge and claimed that typhoid fever had distinct features in Colombia. The focus on paludic and typhoid fevers in the highlands might explain why the bacteriological aetiology of typhoid fever was ignored and even contested during the 1880s. Anti-Pasteurian arguments were raised against its germ identity and some physicians even supported the idea of spontaneous origin of the disease. By the 1890s, Pasteurian knowledge had come to shape clinical and hygienic practices.

Determining the Full Halo Coronal Mass Ejection Characteristics

NASA Astrophysics Data System (ADS)

Fainshtein, V. G.

2010-11-01

Observing halo coronal mass ejections (HCMEs) in the coronagraph field of view allows one to only determine the apparent parameters in the plane of the sky. Recently, several methods have been proposed allowing one to find some true geometrical and kinematical parameters of HCMEs. In most cases, a simple cone model was used to describe the CME shape. Observations show that various modifications of the cone model ("ice cream models") are most appropriate for describing the shapes of individual CMEs. This paper uses the method of determining full HCME parameters proposed by the author earlier, for determining the parameters of 45 full HCMEs, with various modifications of their shapes. I show that the determined CME characteristics depend significantly on the chosen CME shape. I conclude that the absence of criteria for a preliminary evaluation of the CME shape is a major source of error in determining the true parameters of a full HCME with any of the known methods. I show that, regardless of the chosen CME form, the trajectory of practically all the HCMEs in question deviate from the radial direction towards the Sun-Earth axis at the initial stage of their movement, and their angular size, on average, significantly exceeds that of all the observable CMEs.

Neuroethics: a guide for the perplexed.

PubMed

Farah, Martha J

2004-01-01

Like filings to a magnet, issues of all shapes, sizes, and degrees of importance are sticking to the idea of neuroethics. Martha Farah, an early thinker in this new field, proposes that, numerous as they are, the problems actually fall into just three categories. She finds that neuroethics has made a quick start sizing up many practical--and some unique--questions swirling up from brain science, but, she writes, watch for challenges that reach beyond these to the metaphysical. Neuroscience may one day explain in terms of neural tissue virtually all aspects of human cognition and emotion--realms traditionally deemed apart from physical law. Thus, we should also expect neuroethics to grapple with our fundamental distinction between persons and mere "things." If mental processes prove to result from purely physical events, this opens to question our notions of consciousness, spirituality, free will, and moral responsibility.

The art and nature of health: a study of therapeutic practice in museums.

PubMed

Mangione, Gemma

2018-02-01

Drawing on ethnographic fieldwork and interviews at a major metropolitan art museum and botanic garden, this article considers the practical accomplishment of American museums' 'health turn' by tracing how museum staff develop therapeutic programmes for visitors with disabilities. In doing so, it considers one of medical sociology's fundamental theoretical questions - how ideologies of health order social life - in an unconventional empirical setting. Acknowledging contemporary arguments for both the relative merits and unintended consequences of this policy trend, I focus instead on the particular institutional arrangements, professional norms, and material cultures of art and nature that shape museums' therapeutic work, so as to reveal its effects. Data reveals ideological similarities, but practical differences, between museological and medical understandings of wellness. Extending a 'medical sociology of practice' to new contexts ultimately foregrounds the contingencies, and diversity, of therapeutic mechanisms and meanings, thereby broadening sociological research on healing and healthism. © 2018 Foundation for the Sociology of Health & Illness.

Designing a grounded theory study: some practicalities.

McCallin, Antoinette M

2003-01-01

Grounded theory is an interpretative research methodology frequently used by social science researchers seeking to discover the underlying social processes shaping interaction. The methodology is useful to create knowledge about the behavioural patterns of a group. The aim of this paper was to discuss some practical issues that the prospective grounded theory researcher planning a small-scale project may consider. Discussion focuses on the basic premises, choosing a version of grounded theory, the research problem, the purpose of study, the research question and the place of the literature in a study. The specific skills required of the grounded theory researcher are considered and some cautions are exercised. The paper may assist student researchers in a critical care setting and may be of interest to their supervisors and experienced. grounded theory researchers.

Management of agricultural soils for greenhouse gas mitigation: Learning from a case study in NE Spain.

A portfolio of agricultural practices is now available that can contribute to reaching European mitigation targets. Among them, the management of agricultural soils has a large potential for reducing GHG emissions or sequestering carbon. Many of the practices are based on well tested agronomic and technical know-how, with proven benefits for farmers and the environment. A suite of practices has to be used since none of the practices can provide a unique solution. However, there are limitations in the process of policy development: (a) agricultural activities are based on biological processes and thus, these practices are location specific and climate, soils and crops determine their agronomic potential; (b) since agriculture sustains rural communities, the costs and potential for implementation have also to be regionally evaluated and (c) the aggregated regional potential of the combination of practices has to be defined in order to inform abatement targets. We believe that, when implementing mitigation practices, three questions are important: Are they cost-effective for farmers? Do they reduce GHG emissions? What policies favour their implementation? This study addressed these questions in three sequential steps. First, mapping the use of representative soil management practices in the European regions to provide a spatial context to upscale the local results. Second, using a Marginal Abatement Cost Curve (MACC) in a Mediterranean case study (NE Spain) for ranking soil management practices in terms of their cost-effectiveness. Finally, using a wedge approach of the practices as a complementary tool to link science to mitigation policy. A set of soil management practices was found to be financially attractive for Mediterranean farmers, which in turn could achieve significant abatements (e.g., 1.34 MtCO2e in the case study region). The quantitative analysis was completed by a discussion of potential farming and policy choices to shape realistic mitigation policy at European regional level. Copyright © 2016 Elsevier Ltd.

Beyond procedural ethics: foregrounding questions of justice in global health research ethics training for students.

PubMed

Hunt, Matthew R; Godard, Beatrice

2013-07-01

Interest in global health is growing among students across many disciplines and fields of study. In response, an increasing number of academic programmes integrate and promote opportunities for international research, service or clinical placements. These activities raise a range of ethical issues and are associated with important training needs for those who participate. In this paper, we focus on research fieldwork conducted in lower income nations by students from more affluent countries and the ethics preparation they would benefit from receiving prior to embarking on these projects. Global health research is closely associated with questions of justice and equity that extend beyond concerns of procedural ethics. Research takes place in and is shaped by matrices of political, social and cultural contexts and concerns. These realities warrant analysis and discussion during research ethics training. Training activities present an opportunity to encourage students to link global health research to questions of global justice, account for issues of justice in planning their own research, and prepare for 'ethics-in-practice' issues when conducting research in contexts of widespread inequality. Sustained engagement with questions of justice and equity during research ethics training will help support students for involvement in global health research.

The role of food culture and marketing activity in health disparities.

Marketing activities have attracted increased attention from scholars interested in racial disparities in obesity prevalence, as well as the prevalence of other preventable conditions. Although reducing the marketing of nutritionally poor foods to racial/ethnic communities would represent a significant step forward in eliminating racial disparities in health, we focus instead on a critical-related question. What is the relationship between marketing activities, food culture, and health disparities? This commentary posits that food culture shapes the demand for food and the meaning attached to particular foods, preparation styles, and eating practices, while marketing activities shape the overall environment in which food choices are made. We build on prior research that explores the socio-cultural context in which marketing efforts are perceived and interpreted. We discuss each element of the marketing mix to highlight the complex relationship between food culture, marketing activities, and health disparities. Copyright © 2011 Elsevier Inc.

The impact of everyday racism on the occupations of African Canadian women.

Beagan, Brenda L; Etowa, Josephine

2009-10-01

Occupational therapy has increasingly explored the impact of cultural differences on occupations but has not yet begun to explore the impact of racism on human occupation. This study with 50 African Canadian women used mixed methods to explore the effects of racism on their occupational experiences. Women aged 40-65 were interviewed in-depth about everyday experiences with racism and overall well-being. Three standardized instruments assessed frequency and stressfulness of race-related experiences. Everyday racism had subtle, almost intangible, impacts, shaping women's engagement with and the meaning of leisure, productive, and caring occupations. As occupational therapy increasingly attends to issues of cultural difference, it is critical to also attend to racism. This means learning to ask thoughtful questions about how racism may shape clients' occupations. Attention to this aspect of the social environment will enhance practice with African-heritage clients and clients from other racial minority groups.

Guiding students towards sensemaking: teacher questions focused on integrating scientific practices with science content

2017-10-01

Science education reforms articulate a vision of ambitious science teaching where teachers engage students in sensemaking discussions and emphasise the integration of scientific practices with science content. Learning to teach in this way is complex, and there are few examples of sensemaking discussions in schools where textbook lessons and teacher-directed discussions are the norm. The purpose of this study was to characterise the questioning practices of an experienced teacher who taught a curricular unit enhanced with educative features that emphasised students' engagement in scientific practices integrated with science content. Analyses indicated the teacher asked four types of questions: explication questions, explanation questions, science concept questions, and scientific practice questions, and she used three questioning patterns including: (1) focusing students on scientific practices, which involved a sequence of questions to turn students back to the scientific practice; (2) supporting students in naming observed phenomena, which involved a sequence of questions to help students use scientific language; and (3) guiding students in sensemaking, which involved a sequence of questions to help students learn about scientific practices, describe evidence, and develop explanations. Although many of the discussions in this study were not yet student-centred, they provide an image of a teacher asking specific questions that move students towards reform-oriented instruction. Implications for classroom practice are discussed and recommendations for future research are provided.

Diagnosing dementia: Ethnography, interactional ethics and everyday moral reasoning.

Hillman, Alexandra

2017-02-01

This article highlights the contribution of ethnography and qualitative sociology to the ethical challenges that frame the diagnosis of dementia. To illustrate this contribution, the paper draws on an ethnographic study of UK memory clinics carried out between 2012 and 2014. The ethnographic data, set alongside other studies and sociological theory, contest the promotion of a traditional view of autonomy; the limiting of the point of ethical interest to a distinct moment of diagnosis disclosure; and the failure to recognise risk and uncertainty in the building of clinical 'facts' and their communication. In addressing these specific concerns, this article contributes to the wider debate over the relationship between sociology and bioethics (medical ethics). At the heart of these debates lies more fundamental questions: how can we best understand and shape moral decision-making and ethics that guide behaviour in medical practice, and what should be the guiding ideas, concepts and methods to inform ethics in the clinic? Using the case of dementia diagnosis, this article illustrates the benefits of an ethnographic approach, not just for understanding this ethical problem but also for exploring if and how a more empirically informed ethics can help shape healthcare practices for the better.

Reporting of incidents or near incidents because of medical devices in French hospitals relies on procedures following European and national guidelines. The authors intend to evaluate hospital staff knowledge on these surveillance procedures as a marker of appropriate application. A telephone survey is conducted on a sample of Paris University hospital staff (n = 327) using a structured questionnaire. Two-hundred sixteen persons completed the questionnaire. The response rate was lower among physicians, especially surgeons paid on an hourly basis. Rates of correct answers were different according to age, seniority, job, and department categories. Physicians and nurses correctly answered questions on theoretical knowledge more often than the other job categories. However, on questions dealing with actual practice conditions, correct answers depended more on age and seniority with a U-shaped distribution (minimum rates in intermediate categories of age and seniority).

Questioning Stakeholder Legitimacy: A Philanthropic Accountability Model.

Kraeger, Patsy; Robichau, Robbie

2017-01-01

Philanthropic organizations contribute to important work that solves complex problems to strengthen communities. Many of these organizations are moving toward engaging in public policy work, in addition to funding programs. This paper raises questions of legitimacy for foundations, as well as issues of transparency and accountability in a pluralistic democracy. Measures of civic health also inform how philanthropic organizations can be accountable to stakeholders. We propose a holistic model for philanthropic accountability that combines elements of transparency and performance accountability, as well as practices associated with the American pluralistic model for democratic accountability. We argue that philanthropic institutions should seek stakeholder and public input when shaping any public policy agenda. This paper suggests a new paradigm, called philanthropic accountability that can be used for legitimacy and democratic governance of private foundations engaged in policy work. The Philanthropic Accountability Model can be empirically tested and used as a governance tool.

2016-01-01

The activities and behaviours of a female head coach of a national rugby union team were recorded in both training and competition, across a whole rugby season, using the newly developed Rugby Coach Activities and Behaviours Instrument (RCABI). The instrument incorporates 24 categories of behaviour, embedded within three forms of activity (training form (TF), playing form (PF) and competitive match) and seven sub-activity types. In contrast to traditional drill-based coaching, 58.5% of the training time was found to have been spent in PF activities. Moreover, the proportion of PF activities increased to a peak average of 83.8% in proximity to the team's annual international championship. Uniquely, one of the coach's most prolific behaviours was conferring with associates (23.3%), highlighting the importance of interactions with assistant coaches, medical staff and others in shaping the coaching process. Additionally, the frequencies of key behaviours such as questioning and praise were found to vary between the different activity forms and types, raising questions about previous conceptions of effective coaching practice. The findings are discussed in the light of the Game Sense philosophy and the role of the head coach.

Are evolving human rights harmless? An examination of English legislation, prostitution and its effect on human relatedness.

Westin, Anna

2014-01-01

This paper addresses key philosophical and social questions that shape the contemporary discourse on prostitution. The initial section outlines the contemporary challenges facing legislative practice on prostitution in England. This involves analysing moral and legal framework surrounding prostitution that has made the current legislative dilemma surrounding prostitution practice possible. The second part of the paper then outlines the history of the philosophy of human rights from Aquinas to the Universal Declaration of Human Rights (1948). The paper concludes by analysing whether the current ontology employed by human rights theory is effective in creating a system of just relatedness between agents, made visible in concrete legislative guidance. I argue that legislation guided by a fragmented teleology and ontological anthropology enables asymmetrical patterns of relatedness that can cause genuine physical and psychological harm to individuals.

Methodological troubles as problems and phenomena: ethnomethodology and the question of 'method' in the social sciences.

PubMed

Greiffenhagen, Christian; Mair, Michael; Sharrock, Wes

2015-09-01

Across the disciplinary frontiers of the social sciences, studies by social scientists treating their own investigative practices as sites of empirical inquiry have proliferated. Most of these studies have been retrospective, historical, after-the-fact reconstructions of social scientific studies mixing interview data with the (predominantly textual) traces that investigations leave behind. Observational studies of in situ work in social science research are, however, relatively scarce. Ethnomethodology was an early and prominent attempt to treat social science methodology as a topic for sociological investigations and, in this paper, we draw out what we see as its distinctive contribution: namely, a focus on troubles as features of the in situ, practical accomplishment of method, in particular, the way that research outcomes are shaped by the local practices of investigators in response to the troubles they encounter along the way. Based on two case studies, we distinguish methodological troubles as problems and methodological troubles as phenomena to be studied, and suggest the latter orientation provides an alternate starting point for addressing social scientists' investigative practices. © London School of Economics and Political Science 2015.

Change the curriculum--or transform the conditions of practice?

PubMed

Clare, J

1993-08-01

This paper explores the notion that contemporary teaching practices reinforce and maintain the legitimacy of traditional relations of power between teachers and students of nursing. Nurse teachers and clinicians have socially constructed and legitimated power over students which acts to constrain the development of critical consciousness. Student-centred learning packages and strategies such as problem-solving, questioning and dialogue may give the impression of student empowerment while leaving the authoritarian nature of teacher-student relationships intact. Furthermore nursing education is premised on the belief that 'real' learning takes place in the classroom (where teaching occurs) and is consolidated by practice (where nursing occurs). This situation creates a major dilemma for all teachers since the contradictions between classroom knowledge and experiential clinical knowledge are seldom officially recognised. The rhetoric of critical social science however, suggests that emancipation and empowerment of teachers and students would follow their enlightenment as to the nature of these contradictions. This assumption discounts the ways in which hegemonic ideology shapes the consciousness of nurses to accept dominant views of what constitutes professional practice or legitimate knowledge and how that may be obtained.

This is explored in a study of local development planning in the city of Vaesteras, Sweden. The case in question is the development of a large out-of-town shopping centre, propelled by the establishment of a new IKEA furniture store. The Healey (2007) framework of planning as strategy making is applied as an analytical framework, together with a focus on power-knowledge relations. In the analysis, we identify a range of mechanisms that produced ineffectiveness by limiting the role of environmental knowledge throughout themore » planning process. The specific mechanisms we identified were related to the overall consensus perspective in local development strategies and plans, a lack of concretisation and integration of various policies and strategies, a range of exclusion mechanisms and an overall focus on mitigation and benefits of the process in question. In practice, these mechanisms were closely intertwined. Our main conclusion is, consequently, that increased effectiveness of EA would require fundamental transformation of the norms, frameworks and routines that implicitly and explicitly guide land use planning in practice. - Highlights: Black-Right-Pointing-Pointer We analyse how EA-ineffectiveness is produced in land use planning practice.

Do Moral Communities Play a Role in Criminal Sentencing? Evidence From Pennsylvania

Ulmer, Jeffery T.; Bader, Christopher; Gault, Martha

2014-01-01

Religion and social control have been a sociological concern since Durkheim and Weber, and the relationship between religion and punishment has long been the subject of speculation. However, surprisingly little empirical research exists on the role of religion or religious context in criminal justice, and almost no research on the role of religious context on actual sentencing practices. We conceptualize the potential relationships between religious context and sentencing severity by drawing from the focal concerns and court community perspectives in the sentencing literature and moral communities theory developed by Rodney Stark. We suspect that Christian moral communities might shape notions of perceived blameworthiness for court community actors. Such moral communities might also affect notions of community protection – affecting perceptions of dangerousness, or perhaps rehabilitation, and might influence practical constraints/consequences (e.g., local political ramifications of harsh or lenient sentences). We examine these questions using a set of hierarchical models using sentencing data from Pennsylvania county courts and data on the religious composition of Pennsylvania counties from the Associated Religion Data Archives. We find that county Christian religious homogeneity increases the likelihood of incarceration. In addition, Christian homogeneity as well as the prevalence of civically engaged denominations in a county condition the effects of important legally relevant determinants of incarceration. Furthermore, we find evidence that Christian homogeneity activates the effect of local Republican electoral dominance on incarceration. We argue that Christian homogeneity effects sentencing practices primarily through local political processes that shape the election of judges and prosecutors PMID:25035522

This article describes DriveWise, an interdisciplinary hospital-based driving assessment program developed in response to clinical concerns about the driving safety of individuals with medical conditions. DriveWise clinicians use evidence-based, functional assessments to determine driving competence. In addition, the program was designed to meet the emotional needs of individuals whose driving safety has been called into question. To date, approximately 380 participants have been assessed through DriveWise. The following report details the DriveWise mission, DriveWise team members, and road test results. We continue to refine the assessment process to promote safety and support the dignity and independence of all participants. The DriveWise interdisciplinary approach to practice is a concrete example of how gerontological education across professions can have direct benefits to the older adult.

Representing the Earth's shape: the polemics surrounding Maupertuis's expedition to Lapland.

Historical accounts of quantification in the physical sciences in the eighteenth century have often been described as a straightforward series of steps in a process of maturation, as instruments and standards advanced in precision. This paper calls into question the self-evidence nature of precision by investigating the production and uses of measurements. In the case of the dispute over the shape of the Earth, centered in Paris in the 1730s, the precision of measurements was a matter to be interpreted, attacked, defended, and represented. The whole messy business, undertaken by the participants to win consensus from their contemporaries, took place in the context of academic politics and the intellectual fashions of the salons and the court. All parties to the dispute claimed to be drawing on precision measurements; evaluating precision turned out to require the use of a range of intellectual, mathematical, instrumental, political, and textual resources. The alleged precision was then used to construct and defend rival scientific programs and practices.

Prescribed burning is used to reduce the occurrence, extent and severity of uncontrolled fires in many flammable landscapes. However, epidemiologic evidence of the human health impacts of landscape fire smoke emissions is shaping fire management practice through increasingly stringent environmental regulation and public health policy. An unresolved question, critical for sustainable fire management, concerns the comparative human health effects of smoke from wild and prescribed fires. Here we review current knowledge of the health effects of landscape fire emissions and consider the similarities and differences in smoke from wild and prescribed fires with respect to the typical combustion conditions and fuel properties, the quality and magnitude of air pollution emissions, and the potential for dispersion to large populations. We further examine the interactions between these considerations, and how they may shape the longer term smoke regimes to which populations are exposed. We identify numerous knowledge gaps and propose a conceptual framework that describes pathways to better understanding of the health trade-offs of prescribed and wildfire smoke regimes.

Controlled, Constrained, or Flexible? How Self-Management Goals Are Shaped By Patient-Provider Interactions.

A person-centered approach to goal-setting, involving collaboration between patients and health professionals, is advocated in policy to support self-management. However, this is difficult to achieve in practice, reducing the potential effectiveness of self-management support. Drawing on observations of consultations between patients and health professionals, we examined how goal-setting is shaped in patient-provider interactions. Analysis revealed three distinct interactional styles. In controlled interactions, health professionals determine patients' goals based on biomedical reference points and present these goals as something patients should do. In constrained interactions, patients are invited to present goals, yet health professionals' language and questions orientate goals toward biomedical issues. In flexible interactions, patients and professionals both contribute to goal-setting, as health professionals use less directive language, create openings, and allow patients to decide on their goals. Findings suggest that interactional style of health professionals could be the focus of interventions when aiming to increase the effectiveness of goal-setting.

"Shattering culture": perspectives on cultural competence and evidence-based practice in mental health services.

PubMed

Good, Mary-Jo DelVecchio; Hannah, Seth Donal

2015-04-01

The concept of culture as an analytic concept has increasingly been questioned by social scientists, just as health care institutions and clinicians have increasingly routinized concepts and uses of culture as means for improving the quality of care for racial and ethnic minorities. This paper examines this tension, asking whether it is possible to use cultural categories to develop evidenced-based practice guidelines in mental health services when these categories are challenged by the increasing hyperdiversity of patient populations and newer theories of culture that question direct connection between group-based social identities and cultural characteristics. Anthropologists have grown concerned about essentializing societies, yet unequal treatment on the basis of cultural, racial, or ethnic group membership is present in medicine and mental health care today. We argue that discussions of culture-patients' culture and the "culture of medicine"-should be sensitive to the risk of improper stereotypes, but should also be sensitive to the continuing significance of group-based discrimination and the myriad ways culture shapes clinical presentation, doctor-patient interactions, the illness experience, and the communication of symptoms. We recommend that mental health professionals consider the local contexts, with greater appreciation for the diversity of lived experience found among individual patients. This suggests a nuanced reliance on broad cultural categories of racial, ethnic, and national identities in evidence-based practice guidelines. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Objectives. The aim of this study was to gather information about the quality and quantity of root canal treatments carried out by general dental practitioners in Turkey. Methods. Questionnaires were given to 1400 dentists who attended the 16th National Congress organized by the Turkish Dental Association. The participants were asked to answer 34 multiple-choice questions. The questions were subdivided into 3 main topics; general information; general approach to endodontic treatment; and cleaning, shaping, and obturation of root canals. The statistical analysis was carried out by an χ 2-test to compare the means at a significance level of P < 0.05. Results. The response rate for this study was 43%. There was a wide variation in the number of root canal treatments completed per month. Nearly 92% of practitioners stated that they never used rubber dam. The most commonly used working length determination technique was radiographic evaluation (P < 0.05). Sodium hypochlorite was the irrigant of choice with varying concentrations and AH Plus was the sealer of choice (P < 0.05). Resin composite was the most frequently used material for final restorations. Conclusions. Endodontic procedures in general practice in Turkey have differences from widely acknowledged quality guidelines. Despite the introduction of new instruments and techniques, most of the general practitioners chose conventional methods. PMID:23251103

2018-01-01

Implementation Science is commonly described as the study of methods and approaches that promote the uptake and use of evidence-based interventions into routine practice and policymaking. In this issue of JABFM , investigators share a wealth of new insights from the frontlines of Implementation Science in primary care: what it is, how we are doing it, and how it is advancing the evidence base of primary care. The breadth of implementation science in primary care is affirmed by the range of topics covered, from thought leader recommendations on future directions for the field, to reports on how best practices in policy and practice are shaping primary care implementation in the United States and Canada. There are also important updates on agents of primary care implementation themselves, such as practice facilitators, geriatric care teams, and family physicians interested in providing obstetric care. Other articles report on novel practice transformation efforts that advance health promotion and disease prevention, and innovative approaches to identifying and addressing social determinants of health in primary care practices and the communities they serve. The articles seem to generate as many new questions as they answer, and highlight the need for continued emphasis on advancing the science of implementation in primary health care. © Copyright 2018 by the American Board of Family Medicine.

The Concept of Ideology in Analysis of Fundamental Questions in Science Education

NASA Astrophysics Data System (ADS)

Säther, Jostein

The use of the concept of `ideology' in interpretation of science education curricula, textbooks and various practises is reviewed, and examples are given by referring to Norwegian curricula and textbooks. The term is proposed to be used in a broad sense about any kind of action-oriented theory based on a system of ideas, or any attempt to approach politics in the light of a system of ideas. Politics in this context is about shaping of education, and is related to forces (i.e., hypothetical impacts of idea systems) which may legitimise, change, or criticise social practices. The focus is (although not in every case) on the hidden, unconscious and critical aspects. The notion ideological aspects is proposed to be related to metaphysical-ontological, epistemological and axiological claims and connotations. Examples of educational issues concerning e.g., aims, compartmentalisation, integration, and fundamentally different ideas about truth, learning and man are mentioned. Searching for a single and unifying concept for the discussing of all of science education's fundamental questions seems however in vain. Therefore a wide range of concepts seems necessary to deepen our understanding of ``the fundamental questions''.

Shape and color naming are inherently asymmetrical: Evidence from practice-based interference.

Stroop interference is characterized by strong asymmetry between word and color naming such that the former is faster and interferes with the latter but not vice versa. This asymmetry is attributed to differential experience with naming in the two dimensions, i.e., words and colors. Here we show that training on visual-verbal paired associate tasks equivalent to color and shape naming, not involving word reading, leads to strongly asymmetric interference patterns. In two experiments adults practiced naming colors and shapes, one dimension more extensively (10days) than the other (2days), depending on group assignment. One experiment used novel shapes (ideograms) and the other familiar geometric shapes, associated with nonsense syllables. In a third experiment participants practiced naming either colors or shapes using cross-category shape and color names, respectively, for 12days. Across experiments, despite equal training of the two groups in naming the two different dimensions, color naming was strongly affected by shape even after extensive practice, whereas shape naming was resistant to interference. To reconcile these findings with theoretical accounts of interference, reading may be conceptualized as involving visual-verbal associations akin to shape naming. An inherent or early-developing advantage for naming shapes may provide an evolutionary substrate for the invention and development of reading. Copyright © 2016 Elsevier B.V. All rights reserved.

Gender in medical ethics: re-examining the conceptual basis of empirical research.

Conradi, Elisabeth; Biller-Andorno, Nikola; Boos, Margarete; Sommer, Christina; Wiesemann, Claudia

2003-01-01

Conducting empirical research on gender in medical ethics is a challenge from a theoretical as well as a practical point of view. It still has to be clarified how gender aspects can be integrated without sustaining gender stereotypes. The developmental psychologist Carol Gilligan was among the first to question ethics from a gendered point of view. The notion of care introduced by her challenged conventional developmental psychology as well as moral philosophy. Gilligan was criticised, however, because her concept of 'two different voices' may reinforce gender stereotypes. Moreover, although Gilligan stressed relatedness, this is not reflected in her own empirical approach, which still focuses on individual moral reflection. Concepts from social psychology can help overcome both problems. Social categories like gender shape moral identity and moral decisions. If morality is understood as being lived through actions of persons in social relationships, gender becomes a helpful category of moral analysis. Our findings will provide a conceptual basis for the question how empirical research in medical ethics can successfully embrace a gendered perspective.

Retrieval practice improves retention of information on later tests. A question remains: When should retrieval occur during learning-interspersed throughout study or at the end of each study period? In a lab experiment, an online experiment, and a classroom study, we aimed to determine the ideal placement (interspersed vs. at-the-end) of retrieval practice questions. In the lab experiment, 64 subjects viewed slides about APA style and answered short-answer practice questions about the content or restudied the slides (restudy condition). The practice questions either appeared 1 every 1-2 slides (interspersed condition), or all at the end of the presentation (at-the-end condition). One week later, subjects returned and answered the same questions on a final test. In the online experiment, 175 subjects completed the same procedure. In the classroom study, 62 undergraduate students took quizzes as part of class lectures. Short-answer practice questions appeared either throughout the lectures (interspersed condition) or at the end of the lectures (at-the-end condition). Nineteen days after the last quiz, students were given a surprise final test. Results from the 3 experiments converge in demonstrating an advantage for interspersing practice questions on the initial tests, but an absence of this advantage on the final test.

Financially supporting and sustaining behavioral health services integrated into primary care settings remains a major barrier to widespread implementation. Sustaining Healthcare Across Integrated Primary Care Efforts (SHAPE) was a demonstration project designed to prospectively examine the cost savings associated with utilizing an alternative payment methodology to support behavioral health services in primary care practices with integrated behavioral health services. Six primary care practices in Colorado participated in this project. Each practice had at least one on-site behavioral health clinician providing integrated behavioral health services. Three practices received non-fee-for-service payments (i.e., SHAPE payment) to support provision of behavioral health services for 18 months. Three practices did not receive the SHAPE payment and served as control practices for comparison purposes. Assignment to condition was nonrandom. Patient claims data were collected for 9 months before the start of the SHAPE demonstration project (pre-period) and for 18 months during the SHAPE project (post-period) to evaluate cost savings. During the 18-month post-period, analysis of the practices' claims data demonstrated that practices receiving the SHAPE payment generated approximately $1.08 million in net cost savings for their public payer population (i.e., Medicare, Medicaid, and Dual Eligible; N = 9,042). The cost savings were primarily achieved through reduction in downstream utilization (e.g., hospitalizations). The SHAPE demonstration project found that non-fee-for-service payments for behavioral health integrated into primary care may be associated with significant cost savings for public payers, which could have implications on future delivery and payment work in public programs (e.g., Medicaid).

Scientific biography, cognitive deficits, and laboratory practice. James McKeen Cattell and early American experimental psychology, 1880-1904.

PubMed

Sokal, Michael M

2010-09-01

Despite widespread interest in individual life histories, few biographies of scientists make use of insights derived from psychology, another discipline that studies people, their thoughts, and their actions. This essay argues that recent theoretical work in psychology and tools developed for clinical psychological practice can help biographical historians of science create and present fuller portraits of their subjects' characters and temperaments and more nuanced analyses of how these traits helped shape their subjects' scientific work. To illustrate this thesis, the essay examines the early career of James McKeen Cattell--an influential late nineteenth- and early twentieth-century experimental psychologist--through a lens offered by psychology and argues that Cattell's actual laboratory practices derived from an "accommodation" to a long-standing "cognitive deficit." These practices in turn enabled Cattell to achieve more precise experimental results than could any of his contemporaries; and their students readily adopted them, along with their behavioral implications. The essay concludes that, in some ways, American psychology's early twentieth-century move toward a behavioral understanding of psychological phenomena can be traced to Cattell's personal cognitive deficit. It closes by reviewing several "remaining general questions" that this thesis suggests.

Brokering at the boundary: A prospective science teacher engages students in inquiry

Meis Friedrichsen, Patricia; Munford, Danusa; Orgill, Marykay

2006-05-01

Using a theoretical perspective of communities of practice, this case study examines a prospective chemistry teacher's inquiry-based teaching during his practicum. Conrad was a former student of an inquiry-oriented science course, Inquiry Empowering Technologies (IET). The research questions were (a) How did Conrad translate the IET inquiry practices during his practicum?; (b) How did the mentor teacher shape Conrad's participation?; (c) In what ways did Conrad negotiate new meanings of inquiry as a result of his practicum? Interview transcripts were the primary data source. Conrad carried many of the IET inquiry practices into his practicum. He equated inquiry with the use of evidence and had students create evidence-based explanations for how soap works. He chose not to incorporate the tentative nature of science. Although traditional in his own teaching, the mentor teacher supported Conrad by allowing him to teach through inquiry and by removing time constraints. As a result of his practicum, Conrad negotiated new meanings of inquiry teaching and developed an expanded view of technology. Conrad believed that high school students needed guidance when engaging in inquiry and that the tentative nature of science does not transfer to secondary chemistry. Implications for theory and practice are given.

LGBT Family Lawyers and Same-Sex Marriage Recognition: How Legal Change Shapes Professional Identity and Practice.

PubMed

Baumle, Amanda K

2018-01-10

Lawyers who practice family law for LGBT clients are key players in the tenuous and evolving legal environment surrounding same-sex marriage recognition. Building on prior research on factors shaping the professional identities of lawyers generally, and activist lawyers specifically, I examine how practice within a rapidly changing, patchwork legal environment shapes professional identity for this group of lawyers. I draw on interviews with 21 LGBT family lawyers to analyze how the unique features of LGBT family law shape their professional identities and practice, as well as their predictions about the development of the practice in a post-Obergefell world. Findings reveal that the professional identities and practice of LGBT family lawyers are shaped by uncertainty, characteristics of activist lawyering, community membership, and community service. Individual motivations and institutional forces work to generate a professional identity that is resilient and dynamic, characterized by skepticism and distrust coupled with flexibility and creativity. These features are likely to play a role in the evolution of the LGBT family lawyer professional identity post-marriage equality.

Portraiture in the Large Lecture: Storying One Chemistry Professor's Practical Knowledge

NASA Astrophysics Data System (ADS)

Eddleton, Jeannine E.

Practical knowledge, as defined by Freema Elbaz (1983), is a complex, practically oriented set of understandings which teachers use to actively shape and direct their work. The goal of this study is the construction of a social science portrait that illuminates the practical knowledge of a large lecture professor of general chemistry at a public research university in the southeast. This study continues Elbaz's (1981) work on practical knowledge with the incorporation of a qualitative and intentionally interventionist methodology which "blurs the boundaries of aesthetics and empiricism in an effort to capture the complexity, dynamics, and subtlety of human experience and organizational life," (Lawrence-Lightfoot & Davis, 1997). This collection of interviews, observations, writings, and reflections is designed for an eclectic audience with the intent of initiating conversation on the topic of the large lecture and is a purposeful attempt to link research and practice. Social science portraiture is uniquely suited to this intersection of researcher and researched, the perfect combination of methodology and analysis for a project that is both product and praxis. The following research questions guide the study. • Are aspects of Elbaz's practical knowledge identifiable in the research conversations conducted with a large lecture college professor? • Is practical knowledge identifiable during observations of Patricia's large lecture? Freema Elbaz conducted research conversations with Sarah, a high school classroom and writing resource teacher who conducted much of her teaching work one on one with students. Patricia's practice differs significantly from Sarah's with respect to subject matter and to scale.

Biogeochemistry of Microbial Mats

DesMarais, David J.; DeVincenizi, D. (Technical Monitor)

2002-01-01

The hierarchical organization of microbial ecosystems determines the rates of processes that shape Earth's environment, define the stage upon which major evolutionary events occurred, and create biosignatures in sediments and atmospheres. In cyanobacterial mats, oxygenic photosynthesis provides energy, organic substrates and oxygen to the ecosystem. Incident light changes with depth in the mat, both in intensity and spectral composition, and counteracting gradients of oxygen and sulfide shape the chemical microenvironment. A combination of benefits and hazards of light, oxygen and sulfide promotes the allocation of the various essential mat processes between light and dark periods and to various depths in the mat. Microliters produce hydrogen, small organic acids, nitrogen and sulfur species. Such compounds fuel a flow of energy and electrons in these ecosystems and thus shape interactions between groups of microorganisms. Coordinated observations of population distribution, abundance, and activity for an entire community are making fundamental questions in ecology accessible. These questions address those factors that sustain the remarkable diversity of microorganisms that are now being revealed by molecular techniques. These questions also target the processes that shape the various kinds of biosignatures that we will seek, both in ancient rocks from Earth and Mars, and in atmospheres of distant planets beyond our Solar System.

Toward automated consumer question answering: automatically separating consumer questions from professional questions in the healthcare domain.

PubMed

2011-12-01

Both healthcare professionals and healthcare consumers have information needs that can be met through the use of computers, specifically via medical question answering systems. However, the information needs of both groups are different in terms of literacy levels and technical expertise, and an effective question answering system must be able to account for these differences if it is to formulate the most relevant responses for users from each group. In this paper, we propose that a first step toward answering the queries of different users is automatically classifying questions according to whether they were asked by healthcare professionals or consumers. We obtained two sets of consumer questions (~10,000 questions in total) from Yahoo answers. The professional questions consist of two question collections: 4654 point-of-care questions (denoted as PointCare) obtained from interviews of a group of family doctors following patient visits and 5378 questions from physician practices through professional online services (denoted as OnlinePractice). With more than 20,000 questions combined, we developed supervised machine-learning models for automatic classification between consumer questions and professional questions. To evaluate the robustness of our models, we tested the model that was trained on the Consumer-PointCare dataset on the Consumer-OnlinePractice dataset. We evaluated both linguistic features and statistical features and examined how the characteristics in two different types of professional questions (PointCare vs. OnlinePractice) may affect the classification performance. We explored information gain for feature reduction and the back-off linguistic category features. The 10-fold cross-validation results showed the best F1-measure of 0.936 and 0.946 on Consumer-PointCare and Consumer-OnlinePractice respectively, and the best F1-measure of 0.891 when testing the Consumer-PointCare model on the Consumer-OnlinePractice dataset. Healthcare consumer questions posted at Yahoo online communities can be reliably classified from professional questions posted by point-of-care clinicians and online physicians. The supervised machine-learning models are robust for this task. Our study will significantly benefit further development in automated consumer question answering. Copyright © 2011 Elsevier Inc.

2013-01-01

The mission of our hospital states: "Patients and their families are treated with compassion in a family-centered care environment that recognizes their physical, emotional, financial, and spiritual needs." Family-centered care is an approach to health care that shapes policies, programs, facility design, and day-to-day interactions among patients and their families, physicians, nurses, and other health care professionals. Health care professionals across all disciplines and in all care environments have the opportunity to advance the practice of patient- and family-centered care. They do so by welcoming patients and their families as partners in care-acknowledging patient and family expertise and strengths, encouraging their input, and acknowledging the value of their observations and perceptions. There is a growing recognition of the importance of patient and family care experiences as a key part of quality care. Through this partnership, patients and their families are viewed as valuable sources of information that can impact the quality of the care they receive. Their perspective on the care they receive can be used to shape effective solutions and target practice improvements in the care delivery experience. As an organization, we have been focused on implementing patient- and family-centered care for many years. We are unique in that we have parents of patients on the hospital staff and regularly seek their input, along with that of our Family Advisory Boards (English and Spanish speaking) and Teen Advisory Board. You have to ask yourself the question, "Are you ready to incorporate patient- and family-centered care into your practice?"

Mechanisms of bacterial morphogenesis: evolutionary cell biology approaches provide new insights.

PubMed

Jiang, Chao; Caccamo, Paul D; Brun, Yves V

2015-04-01

How Darwin's "endless forms most beautiful" have evolved remains one of the most exciting questions in biology. The significant variety of bacterial shapes is most likely due to the specific advantages they confer with respect to the diverse environments they occupy. While our understanding of the mechanisms generating relatively simple shapes has improved tremendously in the last few years, the molecular mechanisms underlying the generation of complex shapes and the evolution of shape diversity are largely unknown. The emerging field of bacterial evolutionary cell biology provides a novel strategy to answer this question in a comparative phylogenetic framework. This relatively novel approach provides hypotheses and insights into cell biological mechanisms, such as morphogenesis, and their evolution that would have been difficult to obtain by studying only model organisms. We discuss the necessary steps, challenges, and impact of integrating "evolutionary thinking" into bacterial cell biology in the genomic era. © 2015 WILEY Periodicals, Inc.

Although most LGBTQ youth become healthy young adults, they often face considerable stress over the course of their lives because of bullying, victimization, and overt/covert discrimination. Families, educational and religious institutions, health care professionals, and communities help shape the experience of LGBTQ transitional age youth. LGBTQ youth have higher rates of depression, suicide, anxiety, posttraumatic stress disorder, alcohol and drug use, and preventable sexually transmitted diseases. When best practice guidelines are followed and key stakeholders take action to support LGBTQ youth, health disparities begin to disappear. Much can be done to change the trajectory for LGBTQ youth through advocacy, education, culturally competent health care, and policy-making. Copyright © 2016 Elsevier Inc. All rights reserved.

Is there anything unique in the ethics of synthetic biology?

PubMed

Heyd, David

2012-01-01

Synthetic biology does not create any ethical dilemmas that have not already been raised in the development of practices such as genetic screening, genetic engineering, and other interventions in the evolutionary processes. The issue is, nevertheless, ethically serious. Two different angles are examined: the philosophical legitimacy of human intervention in the shaping of human nature, and the more pragmatic (though by no means less important) question of the risks involved in such a novel line of research. As for the first, the claim made here is that in principle there is no constraint in human intervention in the world, since ultimately the source of any value lies in human interests, welfare, and values. This is an approach that is opposite to Habermas's. As for the practical problem of risk, research in synthetic biology calls for particular caution, since in at least the first stages of a new research or program, there is no social regulation, and society is wholly dependent on the scientist's ethical integrity.

An exploration of the assessment experiences of new academics as they engage with a community of practice in higher education.

PubMed

Garrow, Amanda; Tawse, Stephen

2009-08-01

This paper considers a phenomenological research study that attempted to explore how new academics were introduced to the assessment process within a Higher Education context. Two key educational perspectives have shaped the interpretation of the studies findings. These are Nonaka and Takeuchi's [Nonaka, I., Takeuchi, H., 1995. The Knowledge Creating Company: How Japanese Companies Create the Dynamics of Innovation. Oxford University Press, New York] model of knowledge conversion and Lave and Wenger's work on communities of practice (1991, 2002). Three key findings emerged from this work. Firstly, the study highlights a number of issues relating to the types of support and guidance that new academics receive. These were divided into formal and informal types that either promoted conformity or facilitated challenge. Secondly, the study suggests that the ways in which experienced academic staff communicate their assessment knowledge and interact with new academics may require further consideration. Finally, the study raises questions about the type of academic that the organisation would wish to develop.

Two basic questions are encountered when operating in the frequency domain: Is there a mode near a particular frequency? If so, how much spectral data near the frequency can be included for modal identification without incurring significant modeling error? For data with high signal-to-noise (s/n) ratios these questions can be addressed using empirical tools such as singular value spectrum. Otherwise they are generally open and can be challenging, e.g., for modes with low s/n ratios or close modes. In this work these questions are addressed using a Bayesian approach. The focus is on operational modal analysis, i.e., with 'output-only' ambient data, where identification uncertainty and modeling error can be significant and their control is most demanding. The approach leads to 'evidence ratios' quantifying the relative plausibility of competing sets of modeling assumptions. The latter involves modeling the 'what-if-not' situation, which is non-trivial but is resolved by systematic consideration of alternative models and using maximum entropy principle. Synthetic and field data are considered to investigate the behavior of evidence ratios and how they should be interpreted in practical applications.

Fundamentals and techniques of nonimaging optics for solar-energy concentration

NASA Astrophysics Data System (ADS)

Winston, R.; Ogallagher, J. J.

1981-10-01

The development of the theoretical formulation of nonimaging optical principles and the investigation of practical questions having to do with the implementation of newly developed designs for solar and other applications are discussed. Forms of ideal concentrators known at present as shapes which do not disturb the lines of flow of a vector field defining the so called vector lux J are discussed. A search for a differential equation (other than div J = 0) was unsuccessful in the geometrical optics framework. However, an extension to the physical optics domain based on new theories of radiometry in partially coherent light was initiated and appears more promising. Linear concentrator designs to reduce gap losses for tubular absorbers were analyzed in detail. Fresnel lenses and less conventional diffractive components (i.e. holograms) were studied. A ray trace optimization of two second stage concentrators was carried out. Experimental measurements and ray trace studies of the response of an actual concentrator shape and absorber configuration for a fabricated prototype shows that deviation from ideal behavior can be accurately modeled.

Sputter crater formation in the case of microsecond pulsed glow discharge in a Grimm-type source. Comparison of direct current and radio frequency modes

Efimova, Varvara; Hoffmann, Volker; Eckert, Jürgen

2012-10-01

Depth profiling with pulsed glow discharge is a promising technique. The application of pulsed voltage for sputtering reduces the sputtering rate and thermal stress and hereby improves the analysis of thin layered and thermally fragile samples. However pulsed glow discharge is not well studied and this limits its practical use. The current work deals with the questions which usually arise when the pulsed mode is applied: Which duty cycle, frequency and pulse length must be chosen to get the optimal sputtering rate and crater shape? Are the well-known sputtering effects of the continuous mode valid also for the pulsed regime? Is there any difference between dc and rf pulsing in terms of sputtering? It is found that the pulse length is a crucial parameter for the crater shape and thermal effects. Sputtering with pulsed dc and rf modes is found to be similar. The observed sputtering effects at various pulsing parameters helped to interpret and optimize the depth resolution of GD OES depth profiles.

Shape-specific perceptual learning in a figure-ground segregation task.

PubMed

Yi, Do-Joon; Olson, Ingrid R; Chun, Marvin M

2006-03-01

What does perceptual experience contribute to figure-ground segregation? To study this question, we trained observers to search for symmetric dot patterns embedded in random dot backgrounds. Training improved shape segmentation, but learning did not completely transfer either to untrained locations or to untrained shapes. Such partial specificity persisted for a month after training. Interestingly, training on shapes in empty backgrounds did not help segmentation of the trained shapes in noisy backgrounds. Our results suggest that perceptual training increases the involvement of early sensory neurons in the segmentation of trained shapes, and that successful segmentation requires perceptual skills beyond shape recognition alone.

Carbon and Oxygen Budgets of Hypersaline Cyanobacterial Mats: Effects of Tidal Cycle and Temperature

NASA Technical Reports Server (NTRS)

DesMarais, David J.; Bebout, Brad M.; Carpenter, Steven; Discipulo, Mykell; Turk, Kendra

2003-01-01

The hierarchical organization of microbial ecosystems determines the rates of processes that shape Earth#s environment, define the stage upon which major evolutionary events occurred, and create biosignatures in sediments and atmospheres. In cyanobacterial mats, oxygenic photosynthesis provides energy, organic substrates and oxygen to the ecosystem. Incident light changes with depth in the mat, both in intensity and spectral composition, and counteracting gradients of oxygen and sulfide shape the chemical microenvironment. A combination of benefits and hazards of light, oxygen and sulfide promotes the allocation of the various essential mat processes between light and dark periods and to various depths in the mat. Microbiota produce hydrogen, small organic acids, and nitrogen and sulfur species. Such compounds fuel a flow of energy and electrons in these ecosystems and thus shape interactions between groups of microorganisms. Coordinated observations of population distribution, abundance, and activity for an entire community are making fundamental questions in ecology accessible. These questions address those factors that sustain the remarkable diversity of microorganisms that are now being revealed by molecular techniques. These questions also target the processes that shape the various kinds of biosignatures that we will seek, both in ancient rocks from Earth and Mars, and in atmospheres of distant planets beyond our Solar System.

Comparison of Content on the American Board of Internal Medicine Maintenance of Certification Examination With Conditions Seen in Practice by General Internists.

2017-06-13

Success on the internal medicine (IM) examination is a central requirement of the American Board of Internal Medicine's (ABIM's) Maintenance of Certification program (MOC). Therefore, it is important to understand the degree to which this examination reflects conditions seen in practice, one dimension of content validity, which focuses on the match between content in the discipline and the topics on the examination questions. To assess whether the frequency of questions on IM-MOC examinations were concordant with the frequency of conditions seen in practice. The 2010-2013 IM-MOC examinations were used to calculate the percentage of questions for 186 medical condition categories from the examination blueprint, which balances examination content by considering importance and frequency of conditions seen in practice. Nationally representative estimates of conditions seen in practice by general internists were estimated from the primary diagnosis for 13 832 office visits (2010-2013 National Ambulatory Medical Care Surveys) and 108 472 hospital stays (2010 National Hospital Discharge Survey). Prevalence of conditions included on the IM-MOC examination questions. The outcome measure was the concordance between the percentages of IM-MOC examination questions and the percentages of conditions seen in practice during either office visits or hospital stays for each of 186 condition categories (eg, diabetes mellitus, ischemic heart disease, liver disease). The concordance thresholds were 0.5 SD of the weighted mean percentages of the applicable 186 conditions seen in practice (0.74% for office visits; 0.51% for hospital stays). If the absolute differences between the percentages of examination questions and the percentages of office visit conditions or hospital stay conditions seen were less than the applicable concordance threshold, then the condition category was judged to be concordant. During the 2010-2013 IM-MOC examination periods, 3600 questions (180 questions per examination form) were administered and 3461 questions (96.1%) were mapped into the 186 study conditions (mean, 18.6 questions per condition). Comparison of the percentages of 186 categories of medical conditions seen in 13 832 office visits and 108 472 hospital stays with the percentages of 3461 questions on IM-MOC examinations revealed that 2389 examination questions (69.0%; 95% CI, 67.5%-70.6% involving 158 conditions) were categorized as concordant. For concordance between questions and office visits only, 2010 questions (58.08%; 95% CI, 56.43%-59.72% of all examination questions) involving 145 conditions were categorized as concordant. For concordance between questions and hospital stays only, 1456 questions (42.07%; 95% CI, 40.42%-43.71% of all examination questions) involving 122 conditions were categorized as concordant. Among questions on IM-MOC examinations from 2010-2013, 69% were concordant with conditions seen in general internal medicine practices, although some areas of discordance were identified.

Time to make the doughnuts: Building and shaping seamless tubes.

PubMed

Sundaram, Meera V; Cohen, Jennifer D

2017-07-01

A seamless tube is a very narrow-bore tube that is composed of a single cell with an intracellular lumen and no adherens or tight junctions along its length. Many capillaries in the vertebrate vascular system are seamless tubes. Seamless tubes also are found in invertebrate organs, including the Drosophila trachea and the Caenorhabditis elegans excretory system. Seamless tube cells can be less than a micron in diameter, and they can adopt very simple "doughnut-like" shapes or very complex, branched shapes comparable to those of neurons. The unusual topology and varied shapes of seamless tubes raise many basic cell biological questions about how cells form and maintain such structures. The prevalence of seamless tubes in the vascular system means that answering such questions has significant relevance to human health. In this review, we describe selected examples of seamless tubes in animals and discuss current models for how seamless tubes develop and are shaped, focusing particularly on insights that have come from recent studies in Drosophila and C. elegans.

Using imagery to identify and characterise core beliefs in women with bulimia nervosa, dieting and non-dieting women.

PubMed

Somerville, Kate; Cooper, Myra

2007-12-01

Women with bulimia nervosa (BN), dieters and non-dieting control participants were questioned about spontaneous imagery linked to concern with food and eating, weight and shape. The downward arrow technique was used to access any associated negative or core beliefs, which were examined for belief, distress and content. A semi-structured interview with open and closed questions was used. Negative self (core) beliefs were successfully accessed, and responses to the interview items had good test-retest and good inter-rater reliability. Patients with BN reported significantly more negative self (core) beliefs than those in the other two groups. Only a very small number of core beliefs about other people or the world in general were reported. Emotional belief ratings appeared to be higher overall than rational belief ratings. Patient's negative self-beliefs contained themes of "self-value", followed by "failure", "self-control" and "physical attractiveness", in descending order of frequency. The findings are discussed in relation to existing research, and implications for cognitive theories of bulimia nervosa and clinical practice are briefly discussed.

Troubled families and individualised solutions: an institutional discourse analysis of alcohol and drug treatment practices involving affected others.

PubMed

Selbekk, Anne Schanche; Sagvaag, Hildegunn

2016-09-01

Research shows that members of the families with patients suffering from alcohol and other drug-related issues (AOD) experience stress and strain. An important question is, what options do AOD treatment have for them when it comes to support? To answer this, we interviewed directors and clinicians from three AOD treatment institutions in Norway. The study revealed that family-oriented practices are gaining ground as a 'going concern'. However, the relative position of family-orientation in the services, is constrained and shaped by three other going concerns related to: (i) discourse on health and illness, emphasising that addiction is an individual medical and psychological phenomenon, rather than a relational one; (ii) discourse on rights and involvement, emphasising the autonomy of the individual patient and their right to define the format of their own treatment; and (iii) discourse on management, emphasising the relationship between cost and benefit, where family-oriented practices are defined as not being cost-effective. All three discourses are connected to underpin the weight placed on individualised practices. Thus, the findings point to a paradox: there is a growing focus on the needs of children and affected family members, while the possibility of performing integrated work on families is limited. © 2016 Foundation for the Sociology of Health & Illness.

Understanding How Domestic Violence Support Services Promote Survivor Well-being: A Conceptual Model.

PubMed

Sullivan, Cris M

2018-01-01

Domestic violence (DV) victim service programs have been increasingly expected by legislators and funders to demonstrate that they are making a significant difference in the lives of those using their services. Alongside this expectation, they are being asked to describe the Theory of Change guiding how they believe their practices lead to positive results for survivors and their children. Having a widely accepted conceptual model is not just potentially useful to funders and policy makers as they help shape policy and practice -- it can also help programs continually reflect upon and improve their work. This paper describes the iterative and collaborative process undertaken to generate a conceptual model describing how DV victim services are expected to improve survivors' lives. The Social and Emotional Well-Being Framework guiding the model is an ideal structure to use to describe the goals and practices of DV programs because this framework: (1) accurately represents DV programs' goal of helping survivors and their children thrive; and (2) recognizes the importance of community, social, and societal context in influencing individuals' social and emotional well-being. The model was designed to guide practice and to generate new questions for research and evaluation that address individual, community, and systems factors that promote or hinder survivor safety and well-being.

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

PubMed

Logren, Aija; Ruusuvuori, Johanna; Laitinen, Jaana

2017-10-01

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

Feelings: what questions best discriminate women with and without eating disorders?

PubMed

Abraham, S F; von Lojewski, A; Anderson, G; Clarke, S; Russell, J

2009-03-01

This study explored feelings that discriminate between eating disorder and community groups of women. Responses to 25 questions about body image (9), eating (8) self-esteem (3) general psychology (5) were collected in 2002-2003 (N=268) and 2005-2006 (N=472). Wilk's lambda was used to test discrimination. The most discriminating psychological questions were: 'feeling unhappy and unable to cope as well as usual', 'unease attending social functions', 'fearing loss of control over emotions'; and for eating questions were: 'feeling uneasy if other people saw you eating', 'feeling preoccupied with food/eating', 'fearing loss of control over eating'. For body image only 'feeling preoccupied with body weight/shape' and 'fearing loss of control over your body' discriminated. Questions relating to weight and shape for self-esteem ('feeling fat', 'fearing weight gain' and 'wanting to lose weight') discriminated poorly. Results for both cohorts were consistent. Preoccupation with thoughts of eating or body image and fear of loss of control of these would be useful additions to eating disorders criteria. Psychological impairment should also be present.

Evidence, Engagement, and Technology: Themes of and the State of Primary Care Practice-based Network Research.

PubMed

Nease, Donald E

2016-01-01

Practice-based research supported by practice-based research network (PBRN) infrastructure has historically provided an important method for challenging guidelines and evidence arising from secondary and tertiary care settings. This sample of current practice-based research in this issue of the JABFM provides an opportunity to ask whether practice-based research continues to address questions relevant to primary care practices and clinicians and whether a PBRN infrastructure is instrumental to maintaining the relevance and feasibility of practice-based research. Based on this issue's articles, the current state of practice-based research seems to be good, at face value addressing relevant issues for primary care practices. Less clear is the degree to which PBRN infrastructures and relationships informed the questions asked and facilitated the implementation of the studies presented. Practice-based research-related articles that routinely report about how study questions arose-from practices and their clinicians, staff and communities, or elsewhere-could help directly answer questions of relevance. In addition, reporting how practices are recruited to practice-based research studies could inform the degree to which ongoing relationships central to PBRNs facilitate the recruitment and conduct of practice-based research. © Copyright 2016 by the American Board of Family Medicine.

Discourse analysis: towards an understanding of its place in nursing.

PubMed

Crowe, Marie

2005-07-01

This paper describes how discourse analysis, and in particular critical discourse analysis, can be used in nursing research, and provides an example to illustrate the techniques involved. Discourse analysis has risen to prominence in the 1980s and 1990s in disciplines such as the social sciences, literary theory and cultural studies and is increasingly used in nursing. This paper investigates discourse analysis as a useful methodology for conducting nursing research. Effective clinical reasoning relies on employing several different kinds of knowledge and research that draw on different perspectives, methodologies and techniques to generate breadth of knowledge and depth of understanding of clinical practices and patients' experiences of those practices. The steps in a discourse analysis include: choosing the text, and identifying the explicit purpose of the text, the processes used for claiming authority connections to other discourses, construction of major concepts, processes of naming and categorizing, construction of subject positions, construction of reality and social relations and implications for the practice of nursing. The limitations of discourse analysis, its relationship to other qualitative approaches and questions for evaluating the rigour of research using discourse analysis are also explored. The example of discourse analysis shows how a text influences the practice of nursing by shaping knowledge, values and beliefs. Discourse analysis can make a contribution to the development of nursing knowledge by providing a research strategy to examine dominant discourses that influence nursing practice.

Adolescent-to-Parent Abuse as a Form of "Domestic Violence": A Conceptual Review.

PubMed

Holt, Amanda

2016-12-01

Across the Global North, adolescent-to-parent abuse (APA) is becoming recognized as a significant social problem and is receiving attention from researchers, policymakers, and practitioners who work in the intersecting fields of juvenile justice, child protection, and domestic violence. One of the key questions shaping current debates concerns the extent to which APA maps onto the contours of domestic violence, in terms of research and theory, policy, and practice. In particular, to what extent can our established ways of working with domestic violence be applied when working with APA? This article begins by reviewing definitions and prevalence rates of APA. It then considers how the problem fits into the "family conflicts" and "gender-based violence" paradigms that are most frequently used to conceptualize domestic violence. The article then examines how APA represents a similar but distinct phenomenon to adult-instigated domestic violence and identifies how its departures represent particular challenges in working toward its elimination. The article concludes by reviewing intervention programs that work with APA and exploring some of the ways in which they adopt and reject elements of good practice from the domestic violence practice field. © The Author(s) 2015.

Can the study of ethics enhance nursing practice?

PubMed

Allmark, Peter

2005-09-01

The aim of this paper is to suggest that the study of ethics and ethical theories can enhance nursing practice. Knowledge of ethical theories can be of practical use to nurses in at least three ways. First, it can help nurses uncover to what extent a problem is an ethical one. The questions faced in practice can be empirical, formal or philosophical. Very often, a practical decision requires us to tackle all three types. In the example of a 'Do not attempt resuscitation' order, deciding on whether such an order is appropriate requires us to answer empirical questions such as how likely any attempt is to achieve success. It also requires us to answer formal questions such as whether the law permits such an order in the present circumstance. Finally, it requires us to answer ethical/philosophical questions, such as how we should weigh up quality of life against quantity. Second, it can enable practitioners to develop skills and tools to tackle ethical/philosophical questions. In this paper I describe two such tools: Socratic questioning and Aristotelian dialectic. Third, it can help practitioners to develop the soundness of their ethical values and beliefs. All ethical reasoning requires us to use our values and beliefs, and attending to them enhances the quality of our reasoning. The study of ethics can enhance nursing practice.

Youth masculinities: compelling male heterosexuality.

PubMed

Richardson, Diane

2010-12-01

This article seeks to extend understandings of heterosexual masculine identities through an examination of young men's constructions of what motivates young men to engage in heterosexual practices and relationships, and what not having sex might mean for them. Using the masculinity literature and work on heterosexuality to frame the discussion and to contextualize the findings, it explores the complex dynamics that frame the relationship between masculinity and heterosexuality. Specifically, how dominant or 'hegemonic' discourses of heterosexuality shape young men's identities, beliefs and behaviour. It considers these questions using empirical data from a qualitative study of young people living in close-knit working-class communities in the North East of England, with a specific focus on cultural and social attitudes towards sexuality and sexual practices. Peer group networks are a key site for the construction and (re)production of masculinity and, therefore, an important arena within which gendered social approval and acceptance is both sought and gained. In this article, I explore the reasons why young men engage in specific types of heterosexual practice in order to gain social approval. A central question is the extent to which heterosexuality is compelling for young men. That young men do feel compelled to behave in certain ways sexually, behaviours that they may be uncomfortable with and/or dislike, and the fact that they feel they are restricted in terms of how they can talk about their experiences within their peer group networks, demonstrates the power of dominant discourses of masculinity in everyday life. This is addressed through an examination of the restrictive effects of normative discourses about male heterosexuality, including their privatizing effects, which suggest that youth masculinities are often experienced in ways that are highly contradictory requiring young men to adopt a range of strategies to deal with this.

Simulated human patients and patient-centredness: The uncanny hybridity of nursing education, technology, and learning to care.

PubMed

Ireland, Aileen V

2017-01-01

Positioned within a hybrid of the human and technology, professional nursing practice has always occupied a space that is more than human. In nursing education, technology is central in providing tools with which practice knowledge is mobilized so that students can safely engage with simulated human patients without causing harm to real people. However, while there is an increased emphasis on deploying these simulated humans as emissaries from person-centred care to demonstrate what it is like to care for real humans, the nature of what is really going on in simulation-what is real and what is simulated-is very rarely discussed and poorly understood. This paper explores how elements of postcolonial critical thought can aid in understanding the challenges of educating nurses to provide person-centred care within a healthcare culture that is increasingly reliant on technology. Because nursing education is itself a hybrid of real and simulated practice, it provides an appropriate case study to explore the philosophical question of technology in healthcare discourse, particularly as it relates to the relationship between the human patient and its uncanny simulated double. Drawing on postcolonial elements such as the uncanny, diaspora, hybridity, and créolité, the hybrid conditions of nursing education are examined in order to open up new possibilities of thinking about how learning to care is entangled with this technological space to assist in shaping professional knowledge of person-centred care. Considering these issues through a postcolonial lens opens up questions about the nature of the difficulty in using simulated human technologies in clinical education, particularly with the paradoxical aim of providing person-centred care within a climate that increasingly characterized as posthuman. © 2016 John Wiley & Sons Ltd.

Integrated and adaptive management of water resources: Tensions, legacies, and the next best thing

DOE Office of Scientific and Technical Information (OSTI.GOV)

Engle, Nathan L.; Johns, Owen R.; Lemos, Maria Carmen

2011-02-01

Integrated water resources management (IWRM) and adaptive management (AM) are two institutional and management paradigms designed to address shortcomings within water systems governance – the limits of hierarchical water institutional arrangements in the case of IWRM and the challenge of making water management decisions under uncertainty in the case of AM. Recently, there has been a trend to merge these paradigms to address the growing complexity of stressors shaping water management, such as globalization and climate change. However, because many of these joint approaches have received little empirical attention, questions remain about how they might work (or not) in practice.more » Here, we explore a few of these issues using empirical research carried out in Brazil. We focus on highlighting the potentially negative interactions, tensions, and tradeoffs between different institutions/mechanisms perceived as desirable as research and practice attempt to make water systems management simultaneously integrated and adaptive. Our examples pertain mainly on the use of techno-scientific knowledge in water management and governance in Brazil’s IWRM model and how it relates to participation, democracy, deliberation, diversity, and adaptability. We show that a legacy of technical and hierarchical management has shaped the integration of management, and subsequently, the degree to which management might also be adaptive. While integrated systems may be more legitimate and accountable than top-down command and control ones, the mechanisms of IWRM may be at odds with the flexible, experimental, and self-organizing nature of AM.« less

Zombie tapeworms in late capitalism: accelerating clinical and reproductive labour in Mira Grant's Parasitology Trilogy.

PubMed

Attebery, Stina

2016-12-01

Biomedicine is increasingly shaped by the speculative economical values of neoliberal capitalism. A key feature of this new bioeconomical regime is the patenting and circulation of organisms and tissue samples, allowing rapid commercialisation of bacterial, animal and human biomedical materials. When thinking about this trend towards commercialisation, we must consider the ways by which biomedicine has been shaped by economics to better address these exploitative relationships between medical researchers and subjects. These fraught questions of agency and exploitation can be addressed through the concept of clinical labour, a term Melinda Cooper and Catherine Waldby coined to discuss embodied forms of labour, including surrogacy, clinical trials and tissue economies, that dominate the post-Fordist biomedical economy. As a genre that extrapolates from contemporary technoscientific practices, science fiction is uniquely positioned to explore the ethics of biomedical research in this neoliberal speculative economy. Science fiction can give human-like agency and affect to microbial, animal and alien life, allowing modified organisms to speak and interact with their creators. Creating these dialogues between commercialised organisms and biomedical researchers makes clear the connections between contemporary clinical practice and exploitative labour relations, illuminating the more troubling aspects of the new bioeconomy and imagining alternatives to this system.

Retrieval practice has been shown to produce significant enhancements in student learning of course information, but the extent to which students make use of retrieval to learn information on their own is unclear. In the current study, students in a large introductory biology course were provided with optional online review questions that could be accessed as Test questions (requiring students to answer the questions before receiving feedback) or as Read questions (providing students with the question and correct answer up-front). Students more often chose to access the questions as Test compared with Read, and students who used the Test questions scored significantly higher on subsequent exams compared with students who used Read questions or did not access the questions at all. Following an in-class presentation of superior exam performance following use of the Test questions, student use of Test questions increased significantly for the remainder of the term. These results suggest that practice questions can be an effective tool for enhancing student achievement in biology and that informing students about performance-based outcomes coincides with increased use of retrieval practice.

Semiparametric methods for estimation of a nonlinear exposure-outcome relationship using instrumental variables with application to Mendelian randomization.

PubMed

Staley, James R; Burgess, Stephen

2017-05-01

Mendelian randomization, the use of genetic variants as instrumental variables (IV), can test for and estimate the causal effect of an exposure on an outcome. Most IV methods assume that the function relating the exposure to the expected value of the outcome (the exposure-outcome relationship) is linear. However, in practice, this assumption may not hold. Indeed, often the primary question of interest is to assess the shape of this relationship. We present two novel IV methods for investigating the shape of the exposure-outcome relationship: a fractional polynomial method and a piecewise linear method. We divide the population into strata using the exposure distribution, and estimate a causal effect, referred to as a localized average causal effect (LACE), in each stratum of population. The fractional polynomial method performs metaregression on these LACE estimates. The piecewise linear method estimates a continuous piecewise linear function, the gradient of which is the LACE estimate in each stratum. Both methods were demonstrated in a simulation study to estimate the true exposure-outcome relationship well, particularly when the relationship was a fractional polynomial (for the fractional polynomial method) or was piecewise linear (for the piecewise linear method). The methods were used to investigate the shape of relationship of body mass index with systolic blood pressure and diastolic blood pressure. © 2017 The Authors Genetic Epidemiology Published by Wiley Periodicals, Inc.

Semiparametric methods for estimation of a nonlinear exposure‐outcome relationship using instrumental variables with application to Mendelian randomization

PubMed Central

Staley, James R.

2017-01-01

ABSTRACT Mendelian randomization, the use of genetic variants as instrumental variables (IV), can test for and estimate the causal effect of an exposure on an outcome. Most IV methods assume that the function relating the exposure to the expected value of the outcome (the exposure‐outcome relationship) is linear. However, in practice, this assumption may not hold. Indeed, often the primary question of interest is to assess the shape of this relationship. We present two novel IV methods for investigating the shape of the exposure‐outcome relationship: a fractional polynomial method and a piecewise linear method. We divide the population into strata using the exposure distribution, and estimate a causal effect, referred to as a localized average causal effect (LACE), in each stratum of population. The fractional polynomial method performs metaregression on these LACE estimates. The piecewise linear method estimates a continuous piecewise linear function, the gradient of which is the LACE estimate in each stratum. Both methods were demonstrated in a simulation study to estimate the true exposure‐outcome relationship well, particularly when the relationship was a fractional polynomial (for the fractional polynomial method) or was piecewise linear (for the piecewise linear method). The methods were used to investigate the shape of relationship of body mass index with systolic blood pressure and diastolic blood pressure. PMID:28317167

This article examines the process of training informal carers on stroke units using the lens of power. Care is usually assumed as a kinship obligation but the state has long had an interest in framing the carer and caring work. Training carers in healthcare settings raises questions about the power of the state and healthcare professionals as its agents to shape expectations and practices related to the caring role. Drawing on Foucault's notion of disciplinary power, we show how disciplinary forms of power exercised in interactions between healthcare professionals and carers shape the engagement and resistance of carers in the process of training. Interview and observational field note extracts are drawn from a multi-sited study of a training programme on stroke units targeting family carers of people with stroke to consider the consequences of subjecting caring to this intervention. We found that the process of training informal carers on stroke units was not simply a matter of transferring skills from professional to lay person, but entailed disciplinary forms of power intended to shape the conduct of the carer. We interrogate the extent to which a specific kind of carer is produced through such an approach, and the wider implications for the participation of carers in training in healthcare settings and the empowerment of carers. © 2017 Foundation for the Sociology of Health & Illness.

Feminist methodologies and engineering education research

NASA Astrophysics Data System (ADS)

Beddoes, Kacey

2013-03-01

This paper introduces feminist methodologies in the context of engineering education research. It builds upon other recent methodology articles in engineering education journals and presents feminist research methodologies as a concrete engineering education setting in which to explore the connections between epistemology, methodology and theory. The paper begins with a literature review that covers a broad range of topics featured in the literature on feminist methodologies. Next, data from interviews with engineering educators and researchers who have engaged with feminist methodologies are presented. The ways in which feminist methodologies shape their research topics, questions, frameworks of analysis, methods, practices and reporting are each discussed. The challenges and barriers they have faced are then discussed. Finally, the benefits of further and broader engagement with feminist methodologies within the engineering education community are identified.

[Gender, socioeconomic status, and ethnicity in the context of health and migration].

Binder-Fritz, C; Rieder, A

2014-09-01

This article deals with the significance of gender as a social determinant of health and questions the influence of gender roles in health-care services. In the context of worldwide migration, women and men of different ethnicity or social class meet with health-care providers in cross-cultural medical settings. This setting is a challenge for the European Region and in order to allow for diversity and gender sensitivity in health-care practice, interventions should address a range of factors. The concept of intersectionality goes beyond gender sensitivity and includes the consideration of other dimensions of difference, such as age, social class, education, and ethnicity. The interaction between these social dimensions of health shapes the health needs of patients and also influences doctor-patient communiation and social interaction.

Nursing in a technological environment: nursing care in the operating room.

Bull, Rosalind; FitzGerald, Mary

2006-02-01

Operating room nurses continue to draw criticism regarding the appropriateness of a nursing presence in the operating room. The technological focus of the theatre and the ways in which nurses in the theatre have shaped and reshaped their practice in response to technological change have caused people within and outside the nursing profession to question whether operating room nursing is a technological rather than nursing undertaking. This paper reports findings from an ethnographic study that was conducted in an Australian operating department. The study examined the contribution of nurses to the work of the operating room through intensive observation and ethnographic interviews. This paper uses selected findings from the study to explore the ways in which nurses in theatre interpret their role in terms of caring in a technological environment.

Changes in the organization of medical practice have impeded humanistic practice and resulted in widespread physician burnout and dissatisfaction. To identify organizational factors that promote or inhibit humanistic practice of medicine by faculty physicians. From January 1, 2015, through December 31, 2016, faculty from eight US medical schools were asked to write reflectively on two open-ended questions regarding institutional-level motivators and impediments to humanistic practice and teaching within their organizations. Sixty eight of the 92 (74%) study participants who received the survey provided written responses. All subjects who were sent the survey had participated in a year-long small-group faculty development program to enhance humanistic practice and teaching. As humanistic leaders, subjects should have insights into motivating and inhibiting factors. Participants' responses were analyzed using the constant comparative method. Motivators included an organizational culture that enhances humanism, which we judged to be the overarching theme. Related themes included leadership supportive of humanistic practice, responsibility to role model humanism, organized activities that promote humanism, and practice structures that facilitate humanism. Impediments included top down organizational culture that inhibits humanism, along with related themes of non-supportive leadership, time and bureaucratic pressures, and non-facilitative practice structures. While healthcare has evolved rapidly, efforts to counteract the negative effects of changes in organizational and practice environments have largely focused on cultivating humanistic attributes in individuals. Our findings suggest that change at the organizational level is at least equally important. Physicians in our study described the characteristics of an organizational culture that supports and embraces humanism. We offer suggestions for organizational change that keep humanistic and compassionate patient care as its central focus.

Socrates was not a pimp: changing the paradigm of questioning in medical education.

PubMed

Kost, Amanda; Chen, Frederick M

2015-01-01

The slang term "pimping" is widely recognized by learners and educators in the clinical learning environment as the act of more senior members of the medical team publicly asking questions of more junior members. Although questioning as a pedagogical practice has many benefits, pimping, as described in the literature, evokes negative emotions in learners and leads to an environment that is not conducive to adult learning. Medical educators may employ pimping as a pedagogic technique because of beliefs that it is a Socratic teaching method. Although problems with pimping have previously been identified, no alternative techniques for questioning in the clinical environment were suggested. The authors posit that using the term "pimping" to describe questioning in medical education is harmful and unprofessional, and they propose clearly defining pimping as "questioning with the intent to shame or humiliate the learner to maintain the power hierarchy in medical education." Explicitly separating pimping from the larger practice of questioning allows the authors to make three recommendations for improving questioning practices. First, educators should examine the purpose of each question they pose to learners. Second, they should apply historic and modern interpretations of Socratic teaching methods that promote critical thinking skills. Finally, they should consider adult learning theories to make concrete changes to their questioning practices. These changes can result in questioning that is more learner centered, aids in the acquisition of knowledge and skills, performs helpful formative and summative assessments of the learner, and improves community in the clinical learning environment.

Cosmologists ask questions about the history and evolution of the universe on the largest spatial and temporal scales. How fast is the universe expanding? What are the densities of the various sorts of mass-energy therein? What is its future? And how and when did it all begin? These cosmic questions may at first seem far-removed from the branch of mathematics known as topology, which is the study of shapes at their most basic. It is not about the angles, corners and planes of geometry, but of pliable shapes and the handles and holes that cannot be changed by bending and stretching. Topologically, a ball is the same as a glass and a single-handled coffee mug is the same as a ring, but clearly their geometries are different. Similarly, we must separate questions about the geometry of the universe from those about its topology.

Ask the right question: a critical step for practicing evidence-based laboratory medicine.

PubMed

Price, Christopher P; Christenson, Robert H

2013-07-01

The purpose of laboratory medicine is to facilitate better decision making in clinical practice and healthcare delivery. Decision making implies an unresolved issue, problem or unmet need. The most important criterion for any investigation to be of value in clinical practice is that it addresses an unmet need. The different ways in which laboratory investigations are utilized in patient care can be represented in the form of questions. It is important that these questions are articulated to highlight the variables that will impact on the effectiveness of the investigation in the scenario being considered. These variables include the characteristics of the patient (or population) and clinical setting, the nature of the decision and action taken on receipt of the test result and the expected outcome. Asking a question is the first step of the evidence-based laboratory medicine (EBLM) cycle, the other steps being acquiring the evidence, critically appraising the evidence, applying the evidence and auditing use of the evidence. Getting the question right determines the quality of the whole process, thus, defines the quality in practice of laboratory medicine. Whilst the main focus of the EBLM cycle is to provide a strong evidence base for use in clinical practice, it is clear that the five steps are equally applicable in commissioning, delivery and audit (performance management) of services. Asking the right question is crucial to improving the quality of evidence, and practice, in laboratory medicine, and should be used in routine laboratory medicine practice and management throughout healthcare.

A meta-ethnography of organisational culture in primary care medical practice.

2014-01-01

Over the past decade, there has been growing international interest in shaping local organisational cultures in primary healthcare. However, the contextual relevance of extant culture assessment instruments to the primary care context has been questioned. The aim of this paper is to derive a new contextually appropriate understanding of the key dimensions of primary care medical practice organisational culture and their inter-relationship through a synthesis of published qualitative research. A systematic search of six electronic databases followed by a synthesis using techniques of meta-ethnography involving translation and re-interpretation. A total of 16 papers were included in the meta-ethnography from the UK, the USA, Canada, Australia and New Zealand that fell into two related groups: those focused on practice organisational characteristics and narratives of practice individuality; and those focused on sub-practice variation across professional, managerial and administrative lines. It was found that primary care organisational culture was characterised by four key dimensions, i.e. responsiveness, team hierarchy, care philosophy and communication. These dimensions are multi-level and inter-professional in nature, spanning both practice and sub-practice levels. The research contributes to organisational culture theory development. The four new cultural dimensions provide a synthesized conceptual framework for researchers to evaluate and understand primary care cultural and sub-cultural levels. The synthesised cultural dimensions present a framework for practitioners to understand and change organisational culture in primary care teams. The research uses an innovative research methodology to synthesise the existing qualitative research and is one of the first to develop systematically a qualitative conceptual framing of primary care organisational culture.

2002-01-01

This study compared three different methods of teaching five basic algebra rules to college students. All methods used the same procedures to teach the rules and included four 50-question review sessions interspersed among the training of the individual rules. The differences among methods involved the kinds of practice provided during the four review sessions. Participants who received cumulative practice answered 50 questions covering a mix of the rules learned prior to each review session. Participants who received a simple review answered 50 questions on one previously trained rule. Participants who received extra practice answered 50 extra questions on the rule they had just learned. Tests administered after each review included new questions for applying each rule (application items) and problems that required novel combinations of the rules (problem-solving items). On the final test, the cumulative group outscored the other groups on application and problem-solving items. In addition, the cumulative group solved the problem-solving items significantly faster than the other groups. These results suggest that cumulative practice of component skills is an effective method of training problem solving.

Experiences with online consultation systems in primary care: case study of one early adopter site

2017-01-01

Background There is a strong policy drive towards implementing alternatives to face-to-face consultations in general practice to improve access, efficiency, and cost-effectiveness. These alternatives embrace novel technologies that are assumed to offer potential to improve care. Aim To explore the introduction of one online consultation system (Tele-Doc) and how it shapes working practices. Design and setting Mixed methods case study in an inner-city general practice. Method The study was conducted through interviews with IT developers, clinicians, and administrative staff, and scrutiny of documents, websites, and demonstrator versions of Tele-Doc, followed by thematic analysis and discourse analysis. Results Three interrelated themes were identified: online consultation systems as innovation, managing the ‘messiness’ of general practice consultations, and redistribution of the work of general practice. These themes raise timely questions about what it means to consult in contemporary general practice. Uptake of Tele-Doc by patients was low. Much of the work of the consultation was redistributed to patients and administrators, sometimes causing misunderstandings. The ‘messiness’ of consultations was hard to eliminate. In-house training focused on the technical application rather than associated transformations to practice work that were not anticipated. GPs welcomed varied modes of consulting, but the aspiration of improved efficiency was not realised in practice. Conclusion Tele-Doc offers a new kind of consultation that is still being worked out in practice. It may offer convenience for patients with discrete, single problems, and a welcome variation to GPs’ workload. Tele-Doc’s potential for addressing more complex problems and achieving efficiency is less clear, and its adoption may involve unforeseeable consequences. PMID:28993306

4. How is the succession of native floodplain vegetation shaped by present-day flow and sediment conditions? Answering these questions will produce baseline data on the current distributions of landforms and habitats (question 1), the extent of the functional floodplain (question 2), and the effects of modern flow and sediment regimes on future floodplain landforms, habitats, and vegetation succession (questions 3 and 4). Addressing questions 1 and 2 is a logical next step because they underlie questions 3 and 4. Addressing these four questions would better characterize the modern Willamette Basin and help in implementing and setting realistic targets for ongoing management strategies, demonstrating their effectiveness at the site and basin scales, and anticipating future trends and conditions.

Power and practices: questions concerning the legislation of health professions in Brazil.

PubMed

Velloso, Isabela S C; Ceci, Christine

2015-07-01

Developments in professional practice can be related to ongoing changes in relations of power among professionals, which often lead to changes in the boundaries of practices. The differing contexts of practices also influence these changing relations among health professionals. Legislation governing professional practice also differs from country to country. In Brazil, over the past 12 years, in a climate of deep disagreement, a new law to regulate medical practice has been discussed. It was sanctioned, or made into law, but with some notable changes, in July 2013. Of interest to us in this paper are the ways the proposed legislation, by setting out the boundaries and scope of medical practice, 'interfered' in the practices of other health professions, undermining many 'independent' practices that have developed over time. However, even taking into account the multiple routes through which practices are established and developed, the role of legislation that seems able to contradict and deny the historical realities of multiple, intersecting practices should be critically interrogated. In this paper, we use the theoretical resources of poststructuralist thinking to explore gaps, ambiguities, and power relations implicit in the discourses that constituted this law. We argue that although the new law can be understood as a social and political device that will interfere in the organization of other health professions' practices, such legislation is only part of what constitutes change in a consolidated professional practice. And while it is important to understand the effects of such legislation, healthcare practices are also realized or 'made real' through ongoing relations of knowledge and power, including, as we will see in this case, activities of resistance. The problem, then, is to understand the practical arrangements, including legislation, traditions and routines, values and knowledge that come to shape the practices of nursing in a particular context. © 2015 John Wiley & Sons Ltd.

Subcellular and supracellular mechanical stress prescribes cytoskeleton behavior in Arabidopsis cotyledon pavement cells

Sampathkumar, Arun; Krupinski, Pawel; Wightman, Raymond

Although it is a central question in biology, how cell shape controls intracellular dynamics largely remains an open question. Here, we show that the shape of Arabidopsis pavement cells creates a stress pattern that controls microtubule orientation, which then guides cell wall reinforcement. Live-imaging, combined with modeling of cell mechanics, shows that microtubules align along the maximal tensile stress direction within the cells, and atomic force microscopy demonstrates that this leads to reinforcement of the cell wall parallel to the microtubules. This feedback loop is regulated: cell-shape derived stresses could be overridden by imposed tissue level stresses, showing how competitionmore » between subcellular and supracellular cues control microtubule behavior. Furthermore, at the microtubule level, we identified an amplification mechanism in which mechanical stress promotes the microtubule response to stress by increasing severing activity.

2015-09-01

Occupational therapy practitioners frequently identify opportunities for international practice. The World Health Organization and the World Federation of Occupational Therapists have encouraged occupational therapists to address transnational issues, social inclusion, and equal access to opportunities grounded in meaningful occupation (WFOT, 2012). This case study describes a partnership between two U.S. schools of occupational therapy and a Cuban community based pediatric clinic. It examines the dynamics that have sustained the partnership despite political, economic, and logistical barriers. The literature is scrutinized to show how this case study fits into other accounts of collaborative international partnerships. Particularly, it investigates structural and institutional conditions that shape international sustainable partnerships. In doing so, we answer the following questions: (1) Under which circumstances do international partnerships emerge and flourish? (2) What structural and institutional conditions shape international sustainable partnerships? And (3) How do partners perceive and experience the bilateral international partnership? It also discusses and illustrates the foundations and development of international partnerships that succeed. Through the use of a case study we illustrate the development of this partnership. Finally, we consider the next steps of this particular sustainable and collaborative international partnership. © 2015 John Wiley & Sons, Ltd.

Performance on innate behaviour during early development as a function of stress level.

PubMed

Ryu, Soojin; De Marco, Rodrigo J

2017-08-10

What is the relationship between the level of acute stress and performance on innate behaviour? The diversity of innate behaviours and lack of sufficient data gathered under the same experimental conditions leave this question unresolved. While evidence points to an inverted-U shaped relationship between the level of acute stress and various measures of learning and memory function, it is unknown the extent to which such a non-linear function applies to performance on innate behaviour, which develops without example or practice under natural circumstances. The fundamental prediction of this view is that moderate stress levels will improve performance, while higher levels will not. Testing this proposition has been difficult because it entails an overall effect that must be invariant to the nature of the stressor, the behaviour under scrutiny and the stimulus that drives it. Here, we report new experimental results showing that developing zebrafish (Danio rerio) under moderate but not higher levels of stress improved their performance on instinctive activities driven by visual, hydrodynamic and thermal inputs.

NASA Astrophysics Data System (ADS)

Snyder, Vicky L.; Broadway, Francis S.

2004-08-01

As teachers committed to educating all students, we need to learn more about how instructional materials shape representations of sexuality and gender. Through its insistent deconstruction of the norms that structure practice and belief, queer theory offers perspectives from which science educators can question assumptions embedded in textbooks. This article applies queer theory to analyze eight biology textbooks used in the United States. Specifically, we ask how biology textbooks address sexuality outside the heterosexual norm and if they propagate heteronormative attitudes. The textbooks examined offer deafening silences, antiseptic factoids, socially sanitized concepts, and politically correct binary-gendered illustrations. In these textbooks, the term homosexuality was used only in the context of AIDS where, along with iv drug users, they were identified as an affected group. The pervasive acceptance of heteronormative behavior privileges students that fit the heterosexual norm, and oppresses through omission and silence those who do not. We offer implications for practice to help science educators broaden their perspectives on the constructs of sexuality and gender to construct new ways of knowing and understanding differences in science classrooms and the natural world.

Optimal Shape in Electromagnetic Scattering by Small Aspherical Particles

NASA Astrophysics Data System (ADS)

Kostinski, A. B.; Mongkolsittisilp, A.

2013-12-01

We consider the question of optimal shape for scattering by randomly oriented particles, e.g., shape causing minimal extinction among those of equal volume. Guided by the isoperimetric property of a sphere, relevant in the geometrical optics limit of scattering by large particles, we examine an analogous question in the low frequency (electrostatics) approximation, seeking to disentangle electric and geometric contributions. To that end, we survey the literature on shape functionals and focus on ellipsoids, giving a simple proof of spherical optimality for the coated ellipsoidal particle. Monotonic increase with asphericity in the low frequency regime for orientation-averaged induced dipole moments and scattering cross-sections is also established. Additional physical insight is obtained from the Rayleigh-Gans (transparent) limit and eccentricity expansions. We propose linking low and high frequency regime in a single minimum principle valid for all size parameters, provided that reasonable size distributions wash out the resonances for inter-mediate size parameters. This proposal is further supported by the sum rule for integrated extinction. Implications for spectro-polarimetric scattering are explicitly considered.

Visualizing the future: technology competency development in clinical medicine, and implications for medical education.

PubMed

Srinivasan, Malathi; Keenan, Craig R; Yager, Joel

2006-01-01

In this article, the authors ask three questions. First, what will physicians need to know in order to be effective in the future? Second, what role will technology play in achieving that high level of effectiveness? Third, what specific skill sets will physicians need to master in order to become effective? Through three case vignettes describing past, present, and potential future medical practices, the authors identify trends in major medical, technological and cultural shifts that will shape medical education and practice. From these cases, the authors generate a series of technology-related competencies and skill sets that physicians will need to remain leaders in the delivery of medical care. Physicians will choose how they will be end-users of technology, technology developers, and/or the interface between users and developers. These choices will guide the types of skills each physician will need to acquire. Finally, the authors explore the implications of these trends for medical educators, including the competencies that will be required of educators as they develop the medical curriculum. Examining historical and social trends, including how users adopt current and emerging technologies, allows us to anticipate changes in the practice of medicine. By considering market pressures, global trends and emerging technologies, medical educators and practicing physicians may prepare themselves for the changes likely to occur in the medical curriculum and in the marketplace.

The moral foundation of the clinical duties of care: needs, duties and human rights.

PubMed

Doyal, L

2001-10-01

It has become fashionable to question attempts to derive internationally agreed duties of clinical care from more general theories of human rights. For example, some argue that such attempts risk moral abstraction through their neglect for the importance of culture and community in shaping moral consciousness and thus often unhelpful in the resolution of concrete moral dilemmas within medicine. Others denounce the importance of general moral principles altogether in bioethics and attempt to articulate what are claimed to be more practical approaches to resolving moral conflict. This paper challenges such arguments. It does so through arguing that: i) all humans everywhere have the same basic human needs; ii) the satisfaction of these needs varies with culture; iii) the imputation of moral duties on others entails respect for their right to basic need satisfaction, including the right to choose between presumptions about the duties and rights of patients which follow from these more general principles and v) problems of moral indeterminancy that arise from putting these principles into practice can be resolved through associated procedural policies of rational negotiation and compromise. The moral importance and practicality of respect for individual human rights within the practice of medicine is thus defended. Indeed, the paper concludes by arguing that without belief in human rights linked to a theory of basic human needs, communitarian theories of morality are incoherent.

Global health education and health promotion have the potential to engage students, scholars, and practitioners in ways that go beyond the classroom teaching routine. This engagement in global communities, can range from reflection on continuing deep-seated questions about human rights and civic responsibility to the use of health education and promotion-related theoretical, intellectual, and practical skills. In the arena of global health education and promotion, these skills also range from leadership and advocacy to decision making, critical and creative thinking, teamwork, and problem solving. In recent times, there has been a growing interest in cross-cultural collaborations and educational initiatives to improve stakeholder's understanding of global health principles and practices, to enrich the experiences of health professionals, and to improve the lives of those who are disenfranchised and live across borders. In this article of Health Promotion Practice, we highlight two unique cases of cross-national collaborations and provide a glimpse of the various shapes and forms taken by cross-cultural educational initiatives for global health education and promotion. We summarize the history, philosophy, and current working practices relevant to these collaborations, keeping in view the global health domains, competencies, and activities. In addition, we also compare the key components and activities of these two case studies from Rwanda and Mexico, wherein communities in these two countries collaborated with academic institutions and health professionals in the United States.

Context and contingency in the history of post World War II nursing scholarship in the United States.

Fairman, Julie

2008-01-01

To examine the context for the development of nursing scholarship post World War II. Historiographical analysis of the social, political, and cultural context of nursing scholarship in the postwar period, with an understanding of how this context shaped nursing scholarship. The development of nursing scholarship was influenced by three contextual strands: Nurses' use of experiential clinical knowledge to situate practice questions in the changing clinical care milieu of the 1950s to the 1970s; The development of an intellectual genealogy through new educational opportunities at the baccalaureate and graduate level from the 1960s to the 1980s that provided the foundation for reintegrating practice and education; and the creation of a growing cadre of nurse scholars and their political influence on the relationship between power, knowledge, and clinical practice. These formulations are critical for understanding how scholarship changed over time and help us understand contemporary clinical practice, its authority structure, how it helps us define a body of knowledge from which practice proceeds, and then, how it responds to public demands. Nursing scholarship is nested in a particular social, political, economic, and cultural context. This context also determines how and why it is generated, debated, and used. Its production does not always follow a rational, logical pattern. Nursing knowledge development is influenced as much by the political underpinnings of health care as it is by social, economic, cultural, and scientific foundations.

Experimental investigation of shaping disturbance observer design for motion control of precision mechatronic stages with resonances

NASA Astrophysics Data System (ADS)

Yang, Jin; Hu, Chuxiong; Zhu, Yu; Wang, Ze; Zhang, Ming

2017-08-01

In this paper, shaping disturbance observer (SDOB) is investigated for precision mechatronic stages with middle-frequency zero/pole type resonance to achieve good motion control performance in practical manufacturing situations. Compared with traditional standard disturbance observer (DOB), in SDOB a pole-zero cancellation based shaping filter is cascaded to the mechatronic stage plant to meet the challenge of motion control performance deterioration caused by actual resonance. Noting that pole-zero cancellation is inevitably imperfect and the controller may even consequently become unstable in practice, frequency domain stability analysis is conducted to find out how each parameter of the shaping filter affects the control stability. Moreover, the robust design criterion of the shaping filter, and the design procedure of SDOB, are both proposed to guide the actual design and facilitate practical implementation. The SDOB with the proposed design criterion is applied to a linear motor driven stage and a voice motor driven stage, respectively. Experimental results consistently validate the effectiveness nature of the proposed SDOB scheme in practical mechatronics motion applications. The proposed SDOB design actually could be an effective unit in the controller design for motion stages of mechanical manufacture equipments.

An interactional ethnographic study of the construction of literate practices of science and writing in a university science classroom

NASA Astrophysics Data System (ADS)

Sena, Nuno Afonso De Freitas Lopes De

An interactional ethnographic study informed by a sociocultural perspective was conducted to examine how a professor and students discursively and interactionally shaped the basis for engaging in the work of a community of geologists. Specifically, the study examined the role the Question of the Day, an interactive writing activity in the lecture, in affording students opportunities for learning the literate practices of science and how to incorporate them in thinking critically. A writing-intensive, introductory oceanography course given in the Geological Sciences Department was chosen because the professor designed it to emphasize writing in the discipline and science literacy within a science inquiry framework. The study was conducted in two phases: a pilot in 2002 and the current study in the Spring Quarter of 2003. Grounded in the view that members in a classroom construct a culture, this study explored the daily construction of the literate practices of science and writing. This view of classrooms was informed by four bodies of research: interactional ethnography, sociolinguistics sociology of science and Writing In the Disciplines. Through participant observation, data were collected in the lecture and laboratory settings in the form of field notes, video, interviews, and artifacts to explore issues of science literacy in discourse, social action, and writing. Examination of participation in the Question of the Day interactive writing activity revealed that it played a key role in initiating and supporting a view of science and inquiry. As the activity permitted collaboration, it encouraged students to engage in the social process to critically explore a discourse of science and key practices with and through their writing. In daily interaction, participants were shown to take up social positions as scientist and engage in science inquiry to explore theory, examine data, and articulately reformulate knowledge in making oral and written scientific arguments. The activity was also shown to provide the professor with a valuable resource to inform his instructional practice, which resulted in enriching the experience of science of students by aligning lectures to address particular concerns. Implications for theory, the teaching of Writing across the Curriculum, and science instruction are discussed.

The only girl in the room: how paradigmatic trajectories deter female students from surgical careers.

PubMed

Hill, Elspeth; Vaughan, Suzanne

2013-06-01

Over 60% of UK medical students are female, yet only 33% of applicants to surgical training are women. Role modelling, differing educational experiences and disidentification in female medical students have been implicated in this disparity. We are yet to fully understand the mechanisms that link students' experiences with national trends in career choices. We employ a hitherto unused concept from the theory of communities of practice: paradigmatic trajectories. These are visible career paths provided by a community and are cited by Wenger as potentially the most influential factors shaping the learning of newcomers. We pioneer the use of this theoretical tool in answering the research question: How do paradigmatic trajectories shape female medical students' experiences of surgery and subsequent career intentions? This qualitative study comprised a secondary analysis of data sourced from 19 clinical medical students. During individual, in-depth, semi-structured interviews, we explored these students' experiences at medical school. We carried out thematic analysis using sensitising concepts from communities of practice theory, notably that of 'paradigmatic trajectories'. Female students' experiences of surgery were strongly gendered; they were positioned as 'other' in the surgical domain. Four key processes--seeing, hearing, doing and imagining--facilitated the formation of paradigmatic trajectories, on which students could draw when making career decisions. Female students were unable to see or identify with other women in surgery. They heard about challenges to being a female surgeon, lacked experiences of participation, and struggled to imagine a future in which they would be successful surgeons. Thus, based on paradigmatic trajectories constructed from exposure to surgery, they self-selected out of surgical careers. By contrast, male students had experiences of 'hands-in' participation and were not marginalised by paradigmatic trajectories. The concept of the paradigmatic trajectory is a useful theoretical tool with which to understand how students' experiences shape career decisions. Paradigmatic trajectories within surgery deter female students from embarking on careers in surgery. © 2013 John Wiley & Sons Ltd.

Adaptive Shape Kernel-Based Mean Shift Tracker in Robot Vision System

PubMed Central

2016-01-01

This paper proposes an adaptive shape kernel-based mean shift tracker using a single static camera for the robot vision system. The question that we address in this paper is how to construct such a kernel shape that is adaptive to the object shape. We perform nonlinear manifold learning technique to obtain the low-dimensional shape space which is trained by training data with the same view as the tracking video. The proposed kernel searches the shape in the low-dimensional shape space obtained by nonlinear manifold learning technique and constructs the adaptive kernel shape in the high-dimensional shape space. It can improve mean shift tracker performance to track object position and object contour and avoid the background clutter. In the experimental part, we take the walking human as example to validate that our method is accurate and robust to track human position and describe human contour. PMID:27379165

Can workers answer their questions about occupational safety and health: challenges and solutions.

Many workers have questions about occupational safety and health (OSH). Answers to these questions empower them to further improve their knowledge about OSH, make good decisions about OSH matters and improve OSH practice when necessary. Nevertheless, many workers fail to find the answers to their questions. This paper explores the challenges workers may face when seeking answers to their OSH questions. Findings suggest that many workers may lack the skills, experience or motivation to formulate an answerable question, seek and find information, appraise information, compose correct answers and apply information in OSH practice. Simultaneously, OSH knowledge infrastructures often insufficiently support workers in answering their OSH questions. This paper discusses several potentially attractive strategies for developing and improving OSH knowledge infrastructures: 1) providing courses that teach workers to ask answerable questions and to train them to find, appraise and apply information, 2) developing information and communication technology tools or facilities that support workers as they complete one or more stages in the process from question to answer and 3) tailoring information and implementation strategies to the workers' needs and context to ensure that the information can be applied to OSH practice more easily.

Qualitative synthesis has become more commonplace in recent years. Meta-ethnography is one of several methods for synthesising qualitative research and is being used increasingly within health care research. However, many aspects of the steps in the process remain ill-defined. We utilized the seven stages of the synthesis process to synthesise qualitative research on adherence to tuberculosis treatment. In this paper we discuss the methodological and practical challenges faced; of particular note are the methods used in our synthesis, the additional steps that we found useful in clarifying the process, and the key methodological challenges encountered in implementing the meta-ethnographic approach. The challenges included shaping an appropriate question for the synthesis; identifying relevant studies; assessing the quality of the studies; and synthesising findings across a very large number of primary studies from different contexts and research traditions. We offer suggestions that may assist in undertaking meta-ethnographies in the future. Meta-ethnography is a useful method for synthesising qualitative research and for developing models that interpret findings across multiple studies. Despite its growing use in health research, further research is needed to address the wide range of methodological and epistemological questions raised by the approach.

Written assessments are essential components of higher education practices. However, faculty members encounter common pitfalls when designing questions intended to evaluate student-learning outcomes. The objective of this project was to determine the impact of a mandatory examination peer review process on question accuracy, alignment with learning objectives, use of best practices in question design, and language/grammar. A mandatory peer review process was implemented for all midterm (before phase) and final (after phase) examinations. Peer review occurred by two reviewers and followed a pre-defined guidance document. Non-punitive feedback given to faculty members served as the intervention. Frequencies of flagged questions according to guidance categories were compared between phases. A total of 21 midterm and 21 final exam reviews were included in the analysis. A total of 637 questions were reviewed across all midterms and 1003 questions were reviewed across all finals. Few questions were flagged for accuracy and alignment with learning outcomes. The median total proportion of questions flagged for best practices was significantly lower for final exams versus midterm exams (15.8 vs. 6.45%, p = 0.014). The intervention did not influence language and grammar errors (9.68 vs. 10.0% of questions flagged before and after, respectively, p = 0.305). A non-punitive peer review process for written examinations can overcome pitfalls in exam creation and improve best practices in question writing. The peer-review process had a substantial effect at flagging language/grammar errors but error rate did not differ between midterm and final exams. Copyright © 2017 Elsevier Inc.

Consequences of animal interactions on their dynamics: emergence of home ranges and territoriality.

Giuggioli, Luca; Kenkre, V M

2014-01-01

Animal spacing has important implications for population abundance, species demography and the environment. Mechanisms underlying spatial segregation have their roots in the characteristics of the animals, their mutual interaction and their response, collective as well as individual, to environmental variables. This review describes how the combination of these factors shapes the patterns we observe and presents a practical, usable framework for the analysis of movement data in confined spaces. The basis of the framework is the theory of interacting random walks and the mathematical description of out-of-equilibrium systems. Although our focus is on modelling and interpreting animal home ranges and territories in vertebrates, we believe further studies on invertebrates may also help to answer questions and resolve unanswered puzzles that are still inaccessible to experimental investigation in vertebrate species.

2015-01-01

This study examined the utility of the Theory of Planned Behavior model, augmented by descriptive norms and justifications, for predicting self-reported research misconduct and questionable research practices in university students. A convenience sample of 205 research active Western Australian university students (47 male, 158 female, ages 18–53 years, M = 22, SD = 4.78) completed an online survey. There was a low level of engagement in research misconduct, with approximately one in seven students reporting data fabrication and one in eight data falsification. Path analysis and model testing in LISREL supported a parsimonious two step mediation model, providing good fit to the data. After controlling for social desirability, the effect of attitudes, subjective norms, descriptive norms and perceived behavioral control on student engagement in research misconduct and questionable research practices was mediated by justifications and then intention. This revised augmented model accounted for a substantial 40.8% of the variance in student engagement in research misconduct and questionable research practices, demonstrating its predictive utility. The model can be used to target interventions aimed at reducing student engagement in research misconduct and questionable research practices. PMID:25983709

Shape Evolution of Metal Nanoparticles in Water Vapor Environment.

Zhu, Beien; Xu, Zhen; Wang, Chunlei; Gao, Yi

2016-04-13

The structures of the metal nanoparticles are crucial for their catalytic activities. How to understand and even control the shape evolution of nanoparticles under reaction condition is a big challenge in heterogeneous catalysis. It has been proved that many reactive gases hold the capability of changing the structures and properties of metal nanoparticles. One interesting question is whether water vapor, such a ubiquitous environment, could induce the shape evolution of metal nanoparticles. So far this question has not received enough attention yet. In this work, we developed a model based on the density functional theory, the Wulff construction, and the Langmuir adsorption isotherm to explore the shape of metal nanoparticle at given temperature and water vapor pressure. By this model, we show clearly that water vapor could notably increase the fraction of (110) facets and decrease that of (111) facets for 3-8 nm Cu nanoparticles, which is perfectly consistent with the experimental observations. Further investigations indicate the water vapor has different effects on the different metal species (Cu, Au, Pt, and Pd). This work not only helps to understand the water vapor effect on the structures of metal nanoparticles but also proposes a simple but effective model to predict the shape of nanoparticles in certain environment.

Retrieval practice with short-answer, multiple-choice, and hybrid tests.

PubMed

Smith, Megan A; Karpicke, Jeffrey D

2014-01-01

Retrieval practice improves meaningful learning, and the most frequent way of implementing retrieval practice in classrooms is to have students answer questions. In four experiments (N=372) we investigated the effects of different question formats on learning. Students read educational texts and practised retrieval by answering short-answer, multiple-choice, or hybrid questions. In hybrid conditions students first attempted to recall answers in short-answer format, then identified answers in multiple-choice format. We measured learning 1 week later using a final assessment with two types of questions: those that could be answered by recalling information verbatim from the texts and those that required inferences. Practising retrieval in all format conditions enhanced retention, relative to a study-only control condition, on both verbatim and inference questions. However, there were little or no advantages of answering short-answer or hybrid format questions over multiple-choice questions in three experiments. In Experiment 4, when retrieval success was improved under initial short-answer conditions, there was an advantage of answering short-answer or hybrid questions over multiple-choice questions. The results challenge the simple conclusion that short-answer questions always produce the best learning, due to increased retrieval effort or difficulty, and demonstrate the importance of retrieval success for retrieval-based learning activities.

Contributions of community psychology to rural advisory services: an analysis of Latin American rural extensionists' point of view.

Landini, Fernando

2015-06-01

During the last decade, rural extension has received interest as being a key tool for rural development. Despite rural extension being affected by many psychosocial processes, psychology has made scarce contributions to it. An investigation was conducted with the aim of gaining knowledge of rural extensionists' expectations of psychology, as well as to contribute to shaping community psychologists' role in the context of rural extension . 652 extensionists from 12 Latin American countries were surveyed. The survey included closed socio-demographic questions as well as open ones addressing extension practice and psychologists' potential contributions. 90.6 % of surveyed extensionists considered psychology could help them improve their practice. Most mentioned areas of contribution go in line with community psychology, including managing farmers groups, facilitating participatory processes and training extensionists; while others, such as the expectation of changing farmers' mindset and increasing the adoption of external technologies, go against its principles. Thus, in some cases, extensionists' expectations could help generate an interesting interaction between community psychology and rural extension, while in others, they need to be put up for discussion. In brief, community psychology has the potential to contribute to rural extension, but it needs to acknowledge extension practice as an interesting area for intervention.

[Gaps of Evidence in ENT-Surgery - a Qualitative Survey].

2016-04-01

As in other disciplines, the burgeoning knowledge in ENT medicine long ago surpassed our ability to adequately absorb it and maintain a proper overview. This can give rise to actual or assumed knowledge gaps that can impede the progress of the discipline and evidence-based treatment of patients. Clinics and medical practices also hold to traditional doctrines that shape day-to-day medicine, without these schools being challenged based on evidence. Between February and June 2015, 160 ENT clinics, including 34 university hospitals, and 2,670 ENT practices took part in a two-arm online survey on existing or perceived evidentiary gaps in ENT medicine using a previously development questionnaire. The survey used for half the participants was open in form; the other half were given a closed survey with systematics of the field for orientation. The survey was augmented with additional data such as the number of publications and focus areas in the clinics and the age and type of practice of the established physicians. The return rate from the clinics was 39.7%; the return rate of the closed surveys was 29.3%. Of the physicians in medical practice, 14.6% responded to the closed and 18.6% to the open survey. There were no major differences between the two forms of survey. Otological and oncological issues comprised approximately 30% of the list of answers from clinics. Corresponding questions were formulated regarding the current diagnostic and therapeutic problems, such as with stage-related tumor treatment or implantable hearing aids. Diagnostic procedures, e.g., special new procedures in audiology and vestibulogy, dominated the surveys from the practices. However clinics and practices alike cited marginal areas of the discipline that are of daily relevance. The cited knowledge gaps then needed to be verified or refuted and clarified based on research of the literature as to whether the existing evidence actually reached healthcare providers in the form of guidelines, publications, conferences or continuing training for application in daily practice. Other steps would include prioritizing future research, evidence mapping, deciding on further systematic reviews, and targeted studies in conjunction with procuring third-party funding and in cooperation with patient associations. The knowledge thus gained should ultimately be transferred in improved form for application in daily clinical practice. Ten questions of key importance each needed to be formulated for the hospitals and practices. © Georg Thieme Verlag KG Stuttgart · New York.

Best Practice Strategies for Effective Use of Questions as a Teaching Tool

PubMed Central

Elsner, Jamie; Haines, Stuart T.

2013-01-01

Questions have long been used as a teaching tool by teachers and preceptors to assess students’ knowledge, promote comprehension, and stimulate critical thinking. Well-crafted questions lead to new insights, generate discussion, and promote the comprehensive exploration of subject matter. Poorly constructed questions can stifle learning by creating confusion, intimidating students, and limiting creative thinking. Teachers most often ask lower-order, convergent questions that rely on students’ factual recall of prior knowledge rather than asking higher-order, divergent questions that promote deep thinking, requiring students to analyze and evaluate concepts. This review summarizes the taxonomy of questions, provides strategies for formulating effective questions, and explores practical considerations to enhance student engagement and promote critical thinking. These concepts can be applied in the classroom and in experiential learning environments. PMID:24052658

Collecting Information About a CAM Practitioner’s Practice: A Preliminary Report of a Self-Interview Methodology

PubMed Central

Elder, William G.; Purdy, Hunter; Bentley, Andrew

2009-01-01

To prepare allopathic providers to advise patients about complementary and alternative medicine (CAM) therapies, the University of Kentucky CAM curriculum integration project has identified and trained CAM practitioners to coteach, precept, and demonstrate their respective practices. This project is interested in integrating CAM practitioners as teachers into this university and has formed a multidisciplinary committee for advice. The committee has recognized the importance of increased understanding of CAM practices to enhance communication within itself and to decide to which CAM practices students should receive exposure. This article reports our attempt to create a CAM practice description, based on questions general to CAM practice and specific to a particular approach. Because there is limited existing systematic research on CAM practice characteristics, these questions may interest researchers conducting qualitative studies, especially those seeking an example of questions to ask CAM practitioners. We also believe this practice description will be of general interest. PMID:19890441

“How Can I Gain Skills if I Don’t Practice?” The Dynamics of Prohibitive Silence against Pre-Marital Pregnancy and Sex in Zimbabwe

2013-01-01

Young people face sexual and reproductive health (SRH) problems including Human immunodeficiency virus (HIV) and Acquired immunodeficiency syndrome (AIDS). It is critical to continue documenting their situation including the contexts they live in. As part of a larger study that explored perspectives of men to SRH and more specifically abortion and contraceptive use, 546 pupils (51% female; age range 9–25 years) from a rural area in Zimbabwe were invited to write anonymously questions about growing up or other questions they could not ask adults for fear or shame. The pupils were included following descriptions by adults of the violence that is unleashed on unmarried young people who engaged in sex, used contraceptives, or simply suggested doing so. The questions by the young people pointed to living in a context of prohibitive silence; their sexuality was silenced and denied. As a consequence they had poor knowledge and their fears and internal conflicts around sexuality and pregnancy were not addressed. Current action suggests concerted effort at the policy level to deal with young people’s SRH in Zimbabwe. It nevertheless remains necessary, as a way to provide support to these efforts, to continue examining what lessons can be drawn from the past, and how the past continues to reflect in and shape present dynamics and relations. There is also need to look more critically at life skill education, which has previously been described as having failed to address adequately the practical needs of young people. Life skill education in Zimbabwe has rarely been systematically evaluated. A fuller understanding is also needed of the different factors co-existing in contemporary African societies and how they have been and continue to be constituted within history, and the implications to the promotion of adolescent SRH.

Connecting pre-marketing clinical research and medical practice: opinion-based study of core issues and possible changes in drug regulation.

Wieringa, Nicolien F; Peschar, Jules L; Denig, Petra; de Graeff, Pieter A; Vos, Rein

2003-01-01

To identify core issues that contribute to the gap between pre-marketing clinical research and practice as seen from the perspective of medical practice, as well as possible changes and potential barriers for dosing this gap. Interviews with 47 physicians and pharmacists who were liaised to drug regulation through their role in the pre- and post-marketing shaping of new cardiovascular drugs. Data were analyzed using methods of grounded theory and analytical evaluations. Six core issues were identified that referred to the standards in drug regulation, the organization of the regulatory system, and conflicting interests. Pre-marketing trials should focus more on populations and research questions relevant to medical practice. In particular, variability in drug responses between subgroups of patients and demonstration of effectiveness should become major principles in drug regulation. An interactive post-marketing process in which public interests are represented was considered necessary to further guide research and development according to the needs in daily practice. Strategies for change could be applied within the present system of drug regulation, or affect its basic principles. Regulatory authorities were primarily identified to initiate changes, but many other parties should be involved. Barriers for change were identified regarding differences in interests between parties, organizational matters, and with respect to broader healthcare policies. Based on the respondents' opinions, there is a need to focus regulatory standards more on the needs in medical practice. Therefore, regulatory authorities should further develop their influence in the pre- and post-marketing drug development process, together with other parties involved, in order to bridge the gap between clinical research and medical practice.

Experiences from the frontline: An exploration of personal advisers' practice with claimants who have health-related needs within UK welfare-to-work provision.

PubMed

Ceolta-Smith, Jenny; Salway, Sarah; Tod, Angela Mary

2018-04-17

Recent UK welfare reforms have been less successful than expected by the Government in supporting unemployed people with long-term illness into work. Frontline workers remain a core element of the new welfare-to-work machinery, but operate within a changed organisational and policy landscape. These changes raise important questions regarding whether and how claimants' health-related barriers to work are considered. This paper examines the UK welfare-to-work frontline worker's role with claimants who have long-term illness. Fieldwork observations in three not-for-profit employment support services and semi-structured interviews with 29 participants (claimants, frontline workers, healthcare professionals and managers) were conducted between 2011 and 2012. Participant observation of the wider welfare-to-work arena was initiated in 2009 and continued until 2013. A qualitative methodology drawing on ethnographic principles was adopted. Thematic analysis of the data was carried out. The findings show that the frontline worker plays a key role in assessing and addressing claimants' health-related barriers to work. Two important health-related role dimensions were identified: a health promoter role which involved giving health promotional advice to claimants about their general health; and a health monitor role which involved observing and questioning claimants about their general health. Frontline workers' practice approaches were shaped by organisational and individual factors. Integration between the National Health Service and employment support services was limited, and the findings suggested improvements were required to ensure an adequate response to claimants' health-related needs to support their journey into work. © 2018 John Wiley & Sons Ltd.

Students' Use of Optional Online Reviews and Its Relationship to Summative Assessment Outcomes in Introductory Biology.

Carpenter, Shana K; Rahman, Shuhebur; Lund, Terry J S; Armstrong, Patrick I; Lamm, Monica H; Reason, Robert D; Coffman, Clark R

2017-01-01

Retrieval practice has been shown to produce significant enhancements in student learning of course information, but the extent to which students make use of retrieval to learn information on their own is unclear. In the current study, students in a large introductory biology course were provided with optional online review questions that could be accessed as Test questions (requiring students to answer the questions before receiving feedback) or as Read questions (providing students with the question and correct answer up-front). Students more often chose to access the questions as Test compared with Read, and students who used the Test questions scored significantly higher on subsequent exams compared with students who used Read questions or did not access the questions at all. Following an in-class presentation of superior exam performance following use of the Test questions, student use of Test questions increased significantly for the remainder of the term. These results suggest that practice questions can be an effective tool for enhancing student achievement in biology and that informing students about performance-based outcomes coincides with increased use of retrieval practice. © 2017 S.

Effect of questions used by psychiatrists on therapeutic alliance and adherence.

PubMed

Thompson, Laura; Howes, Christine; McCabe, Rose

2016-07-01

Psychiatrists' questions are the mechanism for achieving clinical objectives and managing the formation of a therapeutic alliance - consistently associated with patient adherence. No research has examined the nature of this relationship and the different practices used in psychiatry. Questions are typically defined in binary terms (e.g. 'open' v 'closed') that may have limited application in practice. To undertake a detailed examination of the types of questions psychiatrists ask patients and explore their association with the therapeutic alliance and patient adherence. A coding protocol was developed to classify questions from 134 out-patient consultations, predominantly by syntactic form. Bivariate correlations with measures of patient adherence and the therapeutic alliance (psychiatrist-rated) were examined and assessed using generalised estimating equations, adjusting for patient symptoms, psychiatrist identity and amount of speech. Psychiatrists used only four of ten question types regularly: yes/no auxiliary questions, 'wh-' questions, declarative questions and tag questions. Only declarative questions predicted better adherence and perceptions of the therapeutic relationship. Conversely, 'wh-' questions - associated with positive symptoms - predicted poorer perceptions of the therapeutic relationship. Declarative questions were frequently used to propose an understanding of patients' experiences, in particular their emotional salience for the patient. A refined defining of questioning practices is necessary to improve communication in psychiatry. The use of declarative questions may enhance alliance and adherence, or index their manifestation in talk, e.g. better mutual understanding. The function of 'so'-prefaced declaratives, also used in psychotherapy, is more nuanced than negatively connotated 'leading' questions. Hearable as displays of empathy, they attend closely to patient experience, while balancing the tasks of assessment and treatment. © The Royal College of Psychiatrists 2016.

A survey in the United States revealed that an alarmingly large percentage of university psychologists admitted having used questionable research practices that can contaminate the research literature with false positive and biased findings. We conducted a replication of this study among Italian research psychologists to investigate whether these findings generalize to other countries. All the original materials were translated into Italian, and members of the Italian Association of Psychology were invited to participate via an online survey. The percentages of Italian psychologists who admitted to having used ten questionable research practices were similar to the results obtained in the United States although there were small but significant differences in self-admission rates for some QRPs. Nearly all researchers (88%) admitted using at least one of the practices, and researchers generally considered a practice possibly defensible if they admitted using it, but Italian researchers were much less likely than US researchers to consider a practice defensible. Participants' estimates of the percentage of researchers who have used these practices were greater than the self-admission rates, and participants estimated that researchers would be unlikely to admit it. In written responses, participants argued that some of these practices are not questionable and they have used some practices because reviewers and journals demand it. The similarity of results obtained in the United States, this study, and a related study conducted in Germany suggest that adoption of these practices is an international phenomenon and is likely due to systemic features of the international research and publication processes.

The influence of formal and informal policies and practices on health care innovation implementation: A mixed-methods analysis.

DiMartino, Lisa D; Birken, Sarah A; Hanson, Laura C; Trogdon, Justin G; Clary, Alecia S; Weinberger, Morris; Reeder-Hayes, Katherine; Weiner, Bryan J

The implementation science literature has contributed important insights regarding the influence of formal policies and practices on health care innovation implementation, whereas informal implementation policies and practices have garnered little attention. The broader literature suggests that informal implementation policies and practices could also influence innovation use. We used the Organizational Theory of Innovation Implementation to further understand the role of formal and informal implementation policies and practices as determinants of implementation effectiveness. We examined their role within the context of initiatives to increase palliative care consultation in inpatient oncology. We used a case study design in two organizational settings within one academic medical center: medical and gynecologic oncology. We completed semistructured interviews with medical (n = 12) and gynecologic (n = 10) oncology clinicians using questions based on organizational theory. Quantitative data assessed implementation effectiveness, defined as aggregated palliative care consult rates within oncology services from 2010 to 2016. Four palliative care clinicians were interviewed to gain additional implementation context insights. Medical oncology employed multiple formal policies and practices including training and clinician prompting to support palliative care consultation and a top-down approach, yet most clinicians were unaware of the policies and practices, contributing to a weak implementation climate. In contrast, gynecologic oncology employed one formal policy (written guideline of criteria for initiating a consult) but also relied on informal policies and practices, such as spontaneous feedback and communication; they adopted a bottom-up approach, contributing to broader clinician awareness and strong implementation climate. Both services exhibited variable, increasing consult rates over time. Informal policies and practices may compensate or substitute for formal policies and practices under certain conditions (e.g., smaller health care organizations). Further research is needed to investigate the role of formal and informal policies and practices in shaping a strong and sustainable implementation climate and subsequent effective innovation implementation.

Answering Student Questions During Examinations: A Descriptive Study of Faculty Beliefs.

Stillwell, Susan B; Krautscheid, Lorretta C

2016-01-01

Examinations are used to evaluate individual student learning. Therefore, fair and consistent administration practices are essential. One issue associated with testing administration practices includes whether or not students should be allowed to ask questions during exams and how faculty should respond. Findings from this descriptive study indicate that faculty believe answering questions disrupts the testing environment, inhibits effective monitoring of the testing environment, and could provide unfair hints to students who ask questions. Yet, faculty permit students to ask questions to clarify unclear wording, to provide definitions, and to appear receptive to student needs. Recommendations for nursing education and research are provided.

Subcellular and supracellular mechanical stress prescribes cytoskeleton behavior in Arabidopsis cotyledon pavement cells

2014-01-01

Although it is a central question in biology, how cell shape controls intracellular dynamics largely remains an open question. Here, we show that the shape of Arabidopsis pavement cells creates a stress pattern that controls microtubule orientation, which then guides cell wall reinforcement. Live-imaging, combined with modeling of cell mechanics, shows that microtubules align along the maximal tensile stress direction within the cells, and atomic force microscopy demonstrates that this leads to reinforcement of the cell wall parallel to the microtubules. This feedback loop is regulated: cell-shape derived stresses could be overridden by imposed tissue level stresses, showing how competition between subcellular and supracellular cues control microtubule behavior. Furthermore, at the microtubule level, we identified an amplification mechanism in which mechanical stress promotes the microtubule response to stress by increasing severing activity. These multiscale feedbacks likely contribute to the robustness of microtubule behavior in plant epidermis. DOI: http://dx.doi.org/10.7554/eLife.01967.001 PMID:24740969

Minimum principles in electromagnetic scattering by small aspherical particles

NASA Astrophysics Data System (ADS)

Kostinski, Alex B.; Mongkolsittisilp, Ajaree

2013-12-01

We consider the question of optimal shapes, e.g., those causing minimal extinction among all shapes of equal volume. Guided by the isoperimetric property of a sphere, relevant in the geometrical optics limit of scattering by large particles, we examine an analogous question in the low frequency approximation, seeking to disentangle electric and geometric contributions. To that end, we survey the literature on shape functionals and focus on ellipsoids, giving a simple discussion of spherical optimality for the coated ellipsoidal particle. Monotonic increase with asphericity in the low frequency regime for orientation-averaged induced dipole moments and scattering cross-sections is also shown. Additional physical insight is obtained from the Rayleigh-Gans (transparent) limit and eccentricity expansions. We propose connecting low and high frequency regimes in a single minimum principle valid for all size parameters, provided that reasonable size distributions of randomly oriented aspherical particles wash out the resonances for intermediate size parameters. This proposal is further supported by the sum rule for integrated extinction.

2017-01-01

A board review question bank was created to assist candidates in their preparation for the 2015 EMS certification examination. We aimed to describe the development of this question bank and evaluate its successes in preparing candidates to obtain EMS subspecialty board certification. An online question bank was developed by 13 subject matter experts who participated as item writers, representing eight different EMS fellowship programs. The online question bank consisted of four practice tests, with each of the tests comprised of 100 questions. The number of candidates who participated in and completed the question bank was calculated. The passing rate among candidates who completed the question bank was calculated and compared to the publicly reported statistics for all candidates. The relationship between candidates' performance on the question bank and subspecialty exam pass rates was determined. A total of 252 candidates took at least one practice test and, of those, 225 candidates completed all four 100-question practice tests. The pass rate on the 2015 EMS certification exam was 79% (95%CI 74-85%) among candidates who completed the question bank, which is 12% higher than the overall pass rate (p = 0.003). Candidates' performance on the question bank was positively associated with overall success on the exam (X 2 = 75.8, p < 0.0001). Achieving a score of ≥ 70% on the question bank was associated with a higher likelihood of passing the exam (OR = 17.8; 95% CI: 8.0-39.6). Completing the question bank program was associated with improved pass rates on the EMS certification exam. Strong performance on the question bank correlated with success on the exam.

The everyday meets the academic: How bilingual Latino/a third graders use sociocultural resources to learn in science and social studies

NASA Astrophysics Data System (ADS)

McIntosh Ciechanowski, Kathryn E.

Driven by questions surrounding the documented "fourth-grade slump" in student test scores and about the content learning of English language learners, this dissertation examines the science and social studies literacy practices of third grade bilingual Latino/as in an urban school. Using qualitative and quantitative methods, I examined three questions: (a) What content area demands are evident in instruction and in the assigned texts that children read? (b) What sociocultural knowledge do students draw on in the reading and writing of content area texts? How does it shape their reading and writing? and (c) What linguistic knowledge do students draw on in the reading and writing of content area texts? How does it shape their reading and writing? These questions are premised on three key tenets from the extant research literature. First, research has documented that middle grade students struggle to make sense of content texts, which could be caused by not only a scarcity of expository texts in early grades but also by discipline-specific demands in the content texts. Second, although all students may struggle to read specialized texts, students from non-mainstream backgrounds may struggle more because they do not possess the social and linguistic capital valued in mainstream schools. Third, sociocultural research has documented the importance of social and cultural funds of knowledge in classroom learning and knowledge construction. Guided by these tenets, I observed for six months in 2 classes and recorded field notes, interviewed participants, collected artifacts, and conducted pre- and post-unit assessments. Analytic methods included quantitative evaluation of assessments and constant comparative and discourse analyses. Findings indicate that the textbooks posed linguistic and conceptual demands and represented multiple discourses including the discourses of the natural and social sciences. To make sense of texts, students drew from various sociocultural resources such as popular culture, family, and children's literature. The teacher was more likely to take up these resources (although briefly) when they tightly aligned with instructional goals. Bilingual students faced great complexity as they drew upon linguistic resources to learn technical language and content in two languages and within multiple academic and everyday discourses.

The question of the precise wall shape of rugby hohlraum has been addressed as part of future megajoule-scale ignition designs. Calculations show that elliptical-shaped holhraum is more efficient than spherical-shaped hohlraum. There is less wall hydrodynamics and less absorption for the inner cone, provided a better control of time-dependent symmetry swings. In this context, we have conducted a series of experiments on the OMEGA laser facility. The goal of these experiments was therefore to characterize energetics with a complete set of laser-plasma interaction measurements and capsule implosion in gas-filled elliptical-shaped hohlraum with comparison with spherical-shaped hohlraum. Experiments results are discussed and compared to FCI2 radiation hydrodynamics simulations.

The efficacy of using antecedent control procedures (practice, multi-sensory input and peer participation) in facilitating orientation to person, place and time with two survivors of traumatic brain injuries were tested in two studies. In the first investigation, a 23-year-old male was treated by presenting the orientation questions orally while being shown questions on written flashcards. Results suggest that correct responses to orientation questions only occurred when flashcards were coupled with oral questioning. The participant responded correctly to nearly 100% of all orientation questions within 2 weeks of initiating flashcards. In the second study, a 19-year-old male was asked to respond in writing to 20 orientation questions in a small group. The group had a leader and 4 TBI patients. Following this, group members who correctly answered the orientation questions, took turns reading orientation questions and providing the correct responses.

Successful adult literacy and basic education programs are notoriously difficult to achieve. One reason for this has to do with how the question, "literacy for what?" is answered for a given program. All too frequently, the answer to that question is shaped more by the goals of the literacy provider than it is by learners' own goals and…

Shaping and Being Shaped by Environments for Learning Science. Continuities with the Space and Democratic Vision of a Century Ago

NASA Astrophysics Data System (ADS)

Cavicchi, Elizabeth

2017-07-01

Environments of learning often remain unnoticed and unacknowledged. This study follows a student and myself as we became aware of our local environment at MIT and welcomed that environment as a vibrant contributor to our learning. We met this environment in part through its educational heritage in two centennial anniversaries: John Dewey's 1916 work Democracy and Education and MIT's 1916 move from Boston to the Cambridge campus designed by architect William Welles Bosworth. Dewey argued that for learning to arise through constructive, active engagement among students, the environment must be structured to accommodate investigation. In designing an environment conducive to practical and inventive studies, Bosworth created organic classical forms harboring the illusion of symmetry, while actually departing from it. Students and I are made open to the effects of this environment through the research pedagogy of "critical exploration in the classroom," which informs my practice of listening and responding, and teaching while researching; it lays fertile grounds for the involvement of one student and myself with our environment. Through viewing the moon and sky by eye, telescope, airplane, and astrolabe, the student developed as an observer. She became connected with the larger universe, and critical of formalisms that encage mind and space. Applying Euclid's geometry to the architecture outdoors, the student noticed and questioned classical features in Bosworth's buildings. By encountering these buildings while accompanied by their current restorer, we came to see means by which their structure and design promote human interaction and environmental sustainability as intrinsic to education. The student responded creatively to Bosworth's buildings through photography, learning view-camera, and darkroom techniques. In Dewey's view, democracy entails rejecting dualisms endemic in academic culture since the Greek classical era. Dewey regarded experimental science, where learners are investigators, as a means of engaging the world without invoking dualism. Although Dewey's theory is seldom practiced, our investigations cohered with Deweyan practice. We experienced the environment with its centennial philosophy and architecture as educational agency supportive of investigation that continues to evolve across personal and collective history.

Neural practice effect during cross-modal selective attention: Supra-modal and modality-specific effects.

PubMed

Xia, Jing; Zhang, Wei; Jiang, Yizhou; Li, You; Chen, Qi

2018-05-16

Practice and experiences gradually shape the central nervous system, from the synaptic level to large-scale neural networks. In natural multisensory environment, even when inundated by streams of information from multiple sensory modalities, our brain does not give equal weight to different modalities. Rather, visual information more frequently receives preferential processing and eventually dominates consciousness and behavior, i.e., visual dominance. It remains unknown, however, the supra-modal and modality-specific practice effect during cross-modal selective attention, and moreover whether the practice effect shows similar modality preferences as the visual dominance effect in the multisensory environment. To answer the above two questions, we adopted a cross-modal selective attention paradigm in conjunction with the hybrid fMRI design. Behaviorally, visual performance significantly improved while auditory performance remained constant with practice, indicating that visual attention more flexibly adapted behavior with practice than auditory attention. At the neural level, the practice effect was associated with decreasing neural activity in the frontoparietal executive network and increasing activity in the default mode network, which occurred independently of the modality attended, i.e., the supra-modal mechanisms. On the other hand, functional decoupling between the auditory and the visual system was observed with the progress of practice, which varied as a function of the modality attended. The auditory system was functionally decoupled with both the dorsal and ventral visual stream during auditory attention while was decoupled only with the ventral visual stream during visual attention. To efficiently suppress the irrelevant visual information with practice, auditory attention needs to additionally decouple the auditory system from the dorsal visual stream. The modality-specific mechanisms, together with the behavioral effect, thus support the visual dominance model in terms of the practice effect during cross-modal selective attention.

Although much has been written about measurement instruments for evaluating critical thinking in nursing, this article describes clinical evaluation strategies for critical thinking. Five methods are discussed: 1) observation of students in practice; 2) questions for critical thinking, including Socratic questioning; 3) conferences; 4) problem-solving strategies; and 5) written assignments. These methods provide a means of evaluating students' critical thinking within the context of clinical practice.

Question Asking in the Science Classroom: Teacher Attitudes and Practices

Eshach, Haim; Dor-Ziderman, Yair; Yefroimsky, Yana

2014-02-01

Despite the wide agreement among educators that classroom learning and teaching processes can gain much from student and teacher questions, their potential is not fully utilized. Adopting the view that reporting both teachers' (of varying age groups) views and actual classroom practices is necessary for obtaining a more complete view of the phenomena at hand, the present study closely examines both cognitive and affective domains of: (a) teachers' views (via interviews) concerning: (1) importance and roles of teacher and student questions, (2) teacher responses, and (3) planning and teacher training; and (b) teachers' actual practices (via classroom observations) concerning: (1) number and (2) level of teacher and student questions, as well as (3) teachers' responses to questions. The data were collected from 3 elementary, 3 middle, and 3 high school science teachers and their respective classroom students. The findings lay out a wide view of classroom questioning and teachers' responses, and relate what actually occurs in classes to teachers' stated views. Some of the study's main conclusions are that a gap exists between how science researchers and teachers view the role of teacher questions: the former highlight the cognitive domain, while the latter emphasize the affective domain.

Warfarin Pharmacogenetics

PubMed Central

Johnson, Julie A.; Cavallari, Larisa H.

2014-01-01

The cytochrome P450 (CYP) 2C9 and vitamin K epoxide reductase complex 1 (VKORC1) genotypes have been strongly and consistently associated with warfarin dose requirements, and dosing algorithms incorporating genetic and clinical information have been shown to be predictive of stable warfarin dose. However, clinical trials evaluating genotype-guided warfarin dosing produced mixed results, calling into question the utility of this approach. Recent trials used surrogate markers as endpoints rather than clinical endpoints, further complicating translation of the data to clinical practice. The present data do not support genetic testing to guide warfarin dosing, but in the setting where genotype data are available, use of such data in those of European ancestry is reasonable. Outcomes data are expected from an on-going trial, observational studies continue, and more work is needed to define dosing algorithms that incorporate appropriate variants in minority populations; all these will further shape guidelines and recommendations on the clinical utility of genotype-guided warfarin dosing.

Systems Science Methods in Public Health

Luke, Douglas A.; Stamatakis, Katherine A.

2012-01-01

Complex systems abound in public health. Complex systems are made up of heterogeneous elements that interact with one another, have emergent properties that are not explained by understanding the individual elements of the system, persist over time and adapt to changing circumstances. Public health is starting to use results from systems science studies to shape practice and policy, for example in preparing for global pandemics. However, systems science study designs and analytic methods remain underutilized and are not widely featured in public health curricula or training. In this review we present an argument for the utility of systems science methods in public health, introduce three important systems science methods (system dynamics, network analysis, and agent-based modeling), and provide three case studies where these methods have been used to answer important public health science questions in the areas of infectious disease, tobacco control, and obesity.

The Influence of Finite-size Sources in Acousto-ultrasonics

NASA Technical Reports Server (NTRS)

Pavlakovic, Brian N.; Rose, Joseph L.

1994-01-01

This work explores the effects that the finite normal axisymmetric traction loading of an infinite isotropic plate has on wave propagation in acousto-ultrasonics (AU), in which guided waves are created using two normal incidence transducers. Although the work also addresses the effects of the transducer pressure distribution and pulse shape, this thesis concentrates on two main questions: how does the transducer's diameter control the phase velocity and frequency spectrum of the response, and how does the plate thickness relate to the plate's excitability? The mathematics of the time-harmonic solution and the physical principles and the practical considerations for AU wave generation are explained. Transient sources are modeled by the linear superposition of the time-harmonic solutions found using the Hankel transform and they are then compared to experimental data to provide insight into the relation between the size of the transducer and the preferred phase velocity.

The forces that have shaped American medicine include a wide set of interrelated changes, among them the changing research, development, and marketing practices of the pharmaceutical industry. This article compares the research and development (R&D) and marketing strategies of the British group Imperial Chemical Industries (ICI, whose Pharmaceutical Division was spun off and merged with the Swedish company Astra to form AstraZeneca) and its French counterpart Rhône-Poulenc (now part of Sanofi-Aventis) in dealing with the American medical market. It examines how, in the process, the relationship between R&D and marketing was altered, and the firms themselves were transformed. The article also questions the extent to which their approaches to this market, one of the most significant markets for drugs in general, and for anticancer drugs in particular, became standardized in the period of "scientific marketing."

Inference in the age of big data: Future perspectives on neuroscience.

PubMed

Bzdok, Danilo; Yeo, B T Thomas

2017-07-15

Neuroscience is undergoing faster changes than ever before. Over 100 years our field qualitatively described and invasively manipulated single or few organisms to gain anatomical, physiological, and pharmacological insights. In the last 10 years neuroscience spawned quantitative datasets of unprecedented breadth (e.g., microanatomy, synaptic connections, and optogenetic brain-behavior assays) and size (e.g., cognition, brain imaging, and genetics). While growing data availability and information granularity have been amply discussed, we direct attention to a less explored question: How will the unprecedented data richness shape data analysis practices? Statistical reasoning is becoming more important to distill neurobiological knowledge from healthy and pathological brain measurements. We argue that large-scale data analysis will use more statistical models that are non-parametric, generative, and mixing frequentist and Bayesian aspects, while supplementing classical hypothesis testing with out-of-sample predictions.

Practicing patients, compassion, and hope at the end of life: mining the passion of Jesus in Luke for a Christian model of dying well.

PubMed

Vogt, Christopher P

2003-01-01

Four centuries ago, Christian moral theologians addressed the issue of dying by turning to scripture and the virtues. This work revives that tradition by showing that careful theological reflection upon the nature of Christian patience, compassion, and hope illuminates the shape of the Good Death. The author draws upon Luke's passion narrative to develop a better understanding of these virtues. He also takes up the question of whether Jesus' death can be a model of dying well for contemporary Christians. Christians are often advised to look to Jesus in his dying as a model for themselves, but this recommendation typically leaves unanswered what exactly it is about Jesus' dying that is to be imitated. The understanding of patience, compassion, and hope developed here provides a means of sorting through this issue.

The 100 Most Cited Articles on Healthcare Simulation: A Bibliometric Review.

Walsh, Chloe; Lydon, Sinéad; Byrne, Dara; Madden, Caoimhe; Fox, Susan; OʼConnor, Paul

2018-06-01

This article provides an overview and synthesis of the 100 most cited healthcare simulation publications to provide insight into the articles that have shaped current knowledge and practice. Searches of the Scopus and Web of Science databases were conducted in July 2017. Most articles were concerned with medical education and training (86%) and were most often published in surgical journals (33%). Manikins (20%), standardized patients (16%), inanimate part-task trainers (16%), fully simulated environments (17%), and virtual reality part-task trainers (14%) were the most commonly featured types of simulators. Healthcare simulation research has matured and grown during the preceding decades. There has been a move away from research questions focused on "does simulation work?" to an assessment of the conditions under which simulation is most effective. It is hoped that providing an overview of highly cited works will help identify topics for further research.

The Moral Economy of Lying: Subjectcraft, Narrative Capital, and Uncertainty in the Politics of Asylum.

PubMed

Beneduce, Roberto

2015-01-01

Based on narratives of asylum-seekers from sub-Saharan Africa in northern Italy, in this article I analyze the narrative strategies used by immigrants to meet the eligibility criteria established by asylum law. For many of them, this means "arranging" biographical details within what I call "a moral economy of lying." The first question I discuss is what types of experience and 'subject positions' these narrative strategies reveal or generate. I then examine the arbitrariness and the bureaucratic violence of the asylum evaluation process, and the role of these procedures in the making of nation-language and current technologies of citizenship. Finally, I consider the politics of testification, recognition, and memory these discourses and practices combine to shape. I analyze these issues from an historical point of view of the politics of identity, truth, and falsehood as imposed in a recent past by colonizers onto the colonized.

Entanglements of instruments and media in investigating organic life.

PubMed

Steigerwald, Joan

2016-06-01

The question what constitutes organic life might be answered variously. This special issue explores how the rendering of life throughout the history of biology has been shaped by various instruments and media. While acknowledging the significance of the theoretical and social scenes of inquiry in which specific tools and techniques develop, and which delimit epistemic possibilities for making sense of life, the issue draws attention to material practices and instrumental mediations in experimental studies of life. Although it might seem self-evident that biology takes as its object of inquiry living organisms, it is productive to regard its subject matter as organic media rather than discrete organisms. The papers gathered in this issue show the rich potential for the critical study of how organic life has been constituted through the tools used to mediate its study. Copyright © 2016 Elsevier Ltd.

Inferring human history in East Asia from Y chromosomes.

PubMed

Wang, Chuan-Chao; Li, Hui

2013-06-03

East Asia harbors substantial genetic, physical, cultural and linguistic diversity, but the detailed structures and interrelationships of those aspects remain enigmatic. This question has begun to be addressed by a rapid accumulation of molecular anthropological studies of the populations in and around East Asia, especially by Y chromosome studies. The current Y chromosome evidence suggests multiple early migrations of modern humans from Africa via Southeast Asia to East Asia. After the initial settlements, the northward migrations during the Paleolithic Age shaped the genetic structure in East Asia. Subsequently, recent admixtures between Central Asian immigrants and northern East Asians enlarged the genetic divergence between southern and northern East Asia populations. Cultural practices, such as languages, agriculture, military affairs and social prestige, also have impacts on the genetic patterns in East Asia. Furthermore, application of Y chromosome analyses in the family genealogy studies offers successful showcases of the utility of genetics in studying the ancient history.

This commentary reflects upon the article along three broad lines. It reflects on the theoretical choices and omissions, particularly highlighting why it is important to adapt the multiple streams framework (MSF) when applying it in a socio-political context like Vietnam's. The commentary also reflects upon the analytical threads tackled by Ha et al; for instance, it highlights the opportunities offered by, and raises questions about the centrality of the Policy Entrepreneur in getting the policy onto the political agenda and in pushing it through. The commentary also dwells on the implications of the article for development aid policies and practices. Throughout, the commentary signposts possible themes for Ha et al to consider for further analysis, and more generally, for future research using Kingdon's multiple streams theory. © 2016 by Kerman University of Medical Sciences.

Expressions of Prayer in Residential Care Homes.

Reimer-Kirkham, Sheryl; Sharma, Sonya; Smith, Brenda; Schutt, Kelly; Janzen, Kyla

2018-01-01

Although the value of spiritual care in the care of older adults is supported by research, few studies have focused specifically on prayer in residential care settings. This ethnographic study with fifteen chaplains and administrators in eleven residential care homes involved analyses of walking interviews and research diaries. Findings revealed the spaces in which prayer happens and the forms it takes. The identities of chaplains-their own spiritual practices, religious beliefs, and positioning within the facility-shaped their dis/comfort with prayer and how they located prayer within public and private spaces. Where organizational leadership endorsed the legitimacy of chaplaincy services, prayer was more likely to be offered. Even in these circumstances, however, religious diversity and questions about secularism left chaplains ambivalent about the appropriateness of prayer. The results demonstrate the relevance of religion and spirituality to residential care, and illustrate how prayer functions as an opportunity for connection and understanding.

Collective actors and corporate targets in tobacco control: a cross-national comparison.

PubMed

Nathanson, Constance A

2005-06-01

Cross-national comparative analysis of tobacco control strategies can alert health advocates to how opportunities for public health action, types of action, and probabilities for success are shaped by political systems and cultures. This article is based on case studies of tobacco control in the United States, Canada, Britain, and France. Two questions are addressed: (a) To whom were the dangers of smoking attributed? and (b) What was the role of collective action--grassroots level organization--in combating these dangers? Activists in Canada, Britain, and France moved earlier than the United States did to target the tobacco industry and the state. Locally based advocacy centered on passive smoking has been far more important in the United States. The author concludes that U.S.-style advocacy has played a major role in this country's smoking decline but is insufficient in and of itself to change the corporate practices of a wealthy and politically powerful industry.

Nowadays, the adoption of BIM processes in the AEC (Architecture, Engineering and Construction) industry means to be oriented towards synergistic workflows, based on informative instruments capable of realizing the virtual model of the building. The target of this article is to speak about the interoperability matter, approaching the subject through a theoretical part and also a practice example, in order to show how these notions are applicable in real situations. In particular, the case study analysed belongs to the Cultural Heritage field, where it is possible to find some difficulties - both in the modelling and sharing phases - due to the complexity of shapes and elements. Focusing on the interoperability between different software, the questions are: What and how many kind of information can I share? Given that this process leads also to a standardization of the modelled parts, is there the possibility of an accuracy loss?

A grounded exploration of the dimensions of managerial capability: A preliminary study of top Australian pharmacist owner-managers.

PubMed

Woods, Phillip; Gapp, Rod; King, Michelle A

2015-01-01

Australian community pharmacies are experiencing challenges, including government prescription pricing reform and a dramatically increasing competitive environment. Enacting appropriate responsive actions requires capable pharmacy managers. 'Capability' implies managing effectively in the present, but with unknown or emerging contexts and with new problems. A conceptual understanding of managerial capability as practiced by pharmacist owner-managers is unavailable in the literature. This research aimed to address the question: How can we understand managerial capability in relation to effective community pharmacy management? The study's objective was to develop preliminary theoretical departure points for continuing research responding to the research question. The objective was approached by exploring how 5 top Australian pharmacy owner-managers accomplish the management of their businesses in a changing business environment. Qualitative research methods were employed to develop a social process perspective of how the managers enact their management practices. In-depth semi-structured life-world interviews were undertaken as the major method of data collection. Interview text thematic analysis was carried out identifying rich conceptual properties and dimensions, which 'dimensionalized' 3 key integrated categories. The findings show how the managers are immersed in their business, managerial and personal practices in a holistic and relational manner. Managerial processes, reported through three conceptual categories, their properties and dimensions, reveal the highly situational nature of the reality the managers were experiencing, including their need to express their personal/professional identity. The properties and dimensions of the category 'learning generatively' in particular, reveal how the pharmacy owner-managers shape their business activities and their emerging context as time passes. The preliminary interpretive view of managerial capability describes the phenomenon as an emergent human accomplishment rather than a possessed ability. This social process perspective enables the inclusion of context with time. The study acts as a formative departure point for continuing research of pharmacist managerial capability which seeks to better understand the linkage between 'knowing' and 'doing'.

A characterization of clinical questions asked by rehabilitation therapists.

PubMed

Kloda, Lorie Andrea; Bartlett, Joan C

2014-04-01

This study explored the information needs of rehabilitation therapists (occupational therapists, physical therapists, and speech-language pathologists) working with patients who have had strokes in order to characterize their clinical questions, defined as their formalized information needs arising in the context of everyday clinical practice. The researchers took a constructivist, interpretive approach, in which fifteen rehabilitation therapists working in various settings were recruited. Data were gathered using diaries, followed by diary-guided interviews, and thematically analyzed using template analysis. Rehabilitation therapists' clinical questions were characterized as having one or more of twelve foci and containing one or more of eight possible structural elements. Findings demonstrate that the evidence-based practice framework currently applied for questions relating to rehabilitation is inadequate for representing rehabilitation therapists' clinical questions. A new framework that is more comprehensive and descriptive is proposed. Librarians working with students and clinicians in rehabilitation can employ knowledge of the twelve foci and the question structure for rehabilitation to guide the reference interview. Instruction on question formulation in evidence-based practice can employ the revised structure for rehabilitation, offering students and clinicians an alternative to the traditional patient, intervention, comparison, outcome (PICO) structure. Information products, including bibliographic databases and synopsis services, can tailor their interfaces according to question foci and prompt users to enter search terms corresponding to any of the eight possible elements found in rehabilitation therapists' clinical questions.

Shell shock, trauma, and the First World War: the making of a diagnosis and its histories.

PubMed

Loughran, Tracey

2012-01-01

During the First World War, thousands of soldiers were treated for "shell shock," a condition which encompassed a range of physical and psychological symptoms. Shell shock has most often been located within a "genealogy of trauma," and identified as an important marker in the gradual recognition of the psychological afflictions caused by combat. In recent years, shell shock has increasingly been viewed as a powerful emblem of the suffering of war. This article, which focuses on Britain, extends scholarly analyses which question characterizations of shell shock as an early form of post-traumatic stress disorder. It also considers some of the methodological problems raised by recasting shell shock as a wartime medical construction rather than an essentially timeless manifestation of trauma. It argues that shell shock must be analyzed as a diagnosis shaped by a specific set of contemporary concerns, knowledges, and practices. Such an analysis challenges accepted understandings of what shell shock "meant" in the First World War, and also offers new perspectives on the role of shell shock in shaping the emergence of psychology and psychiatry in the early part of the twentieth century. The article also considers what relation, if any, might exist between intellectual and other histories, literary approaches, and perceptions of trauma as timeless and unchanging.

Class and Health Inequality in Later Life: Patterns, Mechanisms and Implications for Policy

PubMed Central

Nazroo, James

2017-01-01

The growth of the post-retirement population, which has occurred as a result of rapid growth in life expectancy coupled with the ageing of the baby boomer cohort, has led to significant concern. This concern, however, typically neglects the heterogeneity of later life experiences and how these are patterned by inequalities that reflect how process of social stratification continue to operate into later life. This paper draws on a programme of work, based on analysis of the English Longitudinal Study of Ageing, to empirically examine questions of inequality in later life. It begins by illustrating the patterning of health inequality. It then investigates the importance of later life contexts and events in shaping inequality through and after the retirement process. In doing so it examines the extent to which later life continues to reflect stable social structures that shape inequalities and, consequently, health and wellbeing in later life. The paper then illustrates how the effects of socioeconomic position on health in later life can be theorised as a product of class processes, borrowing in part from Bourdieu. Other dimensions of inequality, such as gender, ethnicity, area and sexuality, are not discussed here. The paper concludes with a discussion of the need for a close focus on inequalities in later life in research, policy and practice. PMID:29292775

The Registrar Research Workshop has been a feature of Australian general practice training since 1994. Twenty five general practice registrars attend the annual 3 day event, which aims to develop registrars' understanding of the research process. Presenters and facilitators are drawn from the academic general practitioner and primary health care research community. Presentations alternate with small group sessions, where groups of five registrars are guided through the process of developing a research question, identifying appropriate research methods, and addressing ethical and funding concerns, before preparing a presentation about their research proposal for their peers. Research questions are developed from unanswered questions that have arisen in registrars' clinical practice.

Knowing how to search for evidence that can inform clinical decisions is a fundamental skill for the practice of evidence-based dentistry. There are many available types of evidence-based resources, characterized by their degrees of coverage of preappraised or summarized evidence at varying levels of processing, from primary studies to systematic reviews and clinical guidelines. The practice of evidence-based dentistry requires familiarity with these resources. In this article, the authors describe the process of searching for evidence: defining the question, identifying the question's nature and main components, and selecting the study design that best addresses the question.

Gender, ageing, and injustice: social and political contexts of bioethics.

PubMed

Dodds, S

2005-05-01

There has been considerable work in bioethics addressing injustice and gender oppression in the provision of healthcare services, in the interaction between client and healthcare professional, and in allocation of healthcare services within a particular hospital or health service. There remain several sites of continued injustice that can only be addressed adequately from a broader analytical perspective, one that attends to the social and political contexts framing healthcare policy and practice. Feminist bioethicists have a strong track record in providing this kind of analysis. Using current Australian aged care and welfare policy this paper demonstrates some of the ways in which issues of gender, age, and social inequity shape bioethical debate, policy, and practice in the areas of aged care and welfare provision. The author develops an argument that demonstrates the gender injustice underlying health care and welfare policy. This argument recognises the inevitability of human dependency relations, and questions the adequacy of current political theories to address the requirements for full and equal citizenship. The author shows that an adequate analysis of the ethics of aged healthcare depends on sufficient consideration of the social and political context within which healthcare policy is framed and an adequate understanding of human dependency.

A cross-cultural analysis of posthumous reproduction: The significance of the gender and margins-of-life perspectives.

Hashiloni-Dolev, Yael; Schicktanz, Silke

2017-06-01

The scholarly discussion of posthumous reproduction (PHR) focuses on informed consent and the welfare of the future child, for the most part overlooking cultural differences between societies. Based on a cross-cultural comparison of legal and regulatory documents, analysis of pivotal cases and study of scholarly and media discussions in Israel and Germany, this paper analyses the relevant ethical and policy issues, and questions how cultural differences shape the practice of PHR. The findings challenge the common classifications of PHR by highlighting the gender perspective and adding brain-dead pregnant women to the debate. Based on this study's findings, four neglected cultural factors affecting social attitudes towards PHR are identified: (i) the relationship between the pregnant woman and her future child; (ii) what constitutes the beginning of life; (iii) what constitutes dying; and (iv) the social agent(s) seeking to have the future child. The paper argues that PHR can be better understood by adding the gender and margins-of-life perspectives, and that future ethical and practical discussions of this issue could benefit from the criteria emerging from this cross-cultural analysis.

From the Anticipatory Corpse to the Participatory Body.

Lysaught, M Therese

2016-12-01

Jeffrey Bishop's The Anticipatory Corpse demonstrates how death is present in and cloaked by contemporary practices of end-of-life care. A key to Bishop's argument is that for modern medicine the cadaver has become epistemologically normative and that a metaphysics shorn of formal and final causes now shapes contemporary healthcare practices. The essays of this symposium laud and interrogate Bishop's argument in three ways. First, they raise critical methodological challenges from the perspectives of human rights, Charles Taylor's concept of social imaginaries, and economics. Second, they demonstrate the analytical power of his argument by detailing how it might be extended to additional issues beyond simply end-of-life care and how it might be brought into conversation with sociology. Third, they engage the constructive turn Bishop takes at the end of the book. Bishop himself also updates readers on the reception of The Anticipatory Corpse, as well as the way his thinking has evolved over the past 5 years since its publication. He also engages the questions, challenges, and openings provided by our authors. © The Author 2016. Published by Oxford University Press, on behalf of the Journal of Medicine and Philosophy Inc.

Is there a role for higher education in preparing nurses?

PubMed

Watson, Roger

2006-12-01

Nurse education is now almost wholly situated within universities internationally. However, issues such as the necessity of higher education for what is seen as a practical occupation and the question of whether or not nursing is a profession arise. Newman viewed universities as places where training was given but character was also formed and self-awareness was developed through exposure to a wide range of disciplines and this type of education has helped to shape other professions. If nursing fulfills the criteria for a profession then it requires nurses to be properly educated in higher education. Poor media images of nursing, opposition from within and outside of the profession and poor funding for research, especially in the UK, where most nurses still do not enter the register with a degree, mean that the place of nursing in higher education remains on the periphery. Nurses must be competent to practice and higher education is not incompatible with the development of competent practitioners. However, higher education should take competent practitioners to a higher level whereby they become capable: able to respond appropriately in unfamiliar situations and to unfamiliar events. This paper argues for the role of higher education for nurses in terms of developing capability.

A comparison of plan-based and abstract MDP reward shaping

Efthymiadis, Kyriakos; Kudenko, Daniel

2014-01-01

Reward shaping has been shown to significantly improve an agent's performance in reinforcement learning. As attention is shifting away from tabula-rasa approaches many different reward shaping methods have been developed. In this paper, we compare two different methods for reward shaping; plan-based, in which an agent is provided with a plan and extra rewards are given according to the steps of the plan the agent satisfies, and reward shaping via abstract Markov decision process (MDPs), in which an abstract high-level MDP of the environment is solved and the resulting value function is used to shape the agent. The comparison is conducted in terms of total reward, convergence speed and scaling up to more complex environments. Empirical results demonstrate the need to correctly select and set up reward shaping methods according to the needs of the environment the agents are acting in. This leads to the more interesting question, is there a reward shaping method which is universally better than all other approaches regardless of the environment dynamics?

Questioning Questions: Elementary Teachers' Adaptations of Investigation Questions Across the Inquiry Continuum

NASA Astrophysics Data System (ADS)

Biggers, Mandy

2018-02-01

Questioning is a central practice in science classrooms. However, not every question translates into a "good" science investigation. Questions that drive science investigations can be provided by many sources including the teacher, the curriculum, or the student. The variations in the source of investigation questions were explored in this study. A dataset of 120 elementary science classroom videos and associated lesson plans from 40 elementary teachers (K-5) across 21 elementary school campuses were scored on an instrument measuring the amount of teacher-direction or student-direction of the lessons' investigation questions. Results indicated that the investigation questions were overwhelmingly teacher directed in nature, with no opportunities for students to develop their own questions for investigation. This study has implications for researchers and practitioners alike, calling attention to the teacher-directed nature of investigation questions in existing science curriculum materials, and the need for teacher training in instructional strategies to adapt their existing curriculum materials across the continuum of teacher-directed and student-directed investigation questions. Teachers need strategies for adapting the teacher-directed questions provided in their existing curriculum materials in order to allow students the opportunity to engage in this essential scientific practice.

Objective: Competence orientation, often based on the CanMEDS model, has become an important goal for modern curricula in medical education. The National Competence Based Catalogue of Learning Objectives for Undergraduate Medical Education (NKLM) has been adopted in Germany. However, it is currently unknown whether the vision of competence orientation has also reached the licensing examination procedures. Methods: Therefore, a prospective, descriptive, single-centre, exemplary study design was applied to evaluate 4051 questions/tasks (from 28 examiners at 7 two-day licensing oral-practical exams) for undergraduate medical students at the University of Ulm. The oral and practical questions/tasks as well as the real bedside assessment were assigned to specific competence roles (NKLM section I), categories (NKLM section II) and taxonomy levels of learning domains. Results: Numerous questions/tasks were set per candidate (day 1/2: 70±24/86±19 questions) in the licensing oral-practical exam. Competence roles beyond the “medical expert” were scarcely considered. Furthermore, practical and communication skills at the bedside were hardly addressed (less than 3/15 min). Strikingly, there was a significant predominance of questions with a low-level taxonomy. Conclusions: The data indicate a misalignment of competence-oriented frameworks and the “real world” licensing practical-oral medical exam, which needs improvement in both evaluation and education processes.

Scientific attitude is need of today's society for peaceful and meaningful living of every person in a multicultural world. A case study was conducted at the Faculty of Teacher Training and Education, University of Riau, Pekanbaru in order to describe the scientific attitude that shaped by research-based teaching (RBT). Eighteen students of English for Biology bilingual program were selected from 88 regular students as a subject of the study. RBT designed consists of 9 steps: 1) field observations, 2) developing research proposals, 3) research proposal seminar, 4) field data collecting, 5) data analyzing & ilustrating, 6) writing research papers, 7) preparing power point slides, 8) creating a scientific poster, 9) seminar & poster session. Data were collected by using check list observation instuments during 14 weeks (course sessions), then analyzed by using descriptive-quantitative method. The results showed that RBT were able to shape critical-mindedness, suspended judgement, respect for evidence, honesty, objectivity, and questioning attitude as well as tolerance of uncertainty. These attitudes which shaped were varies according to every steps of learning activities. It's seems that the preparation of scientific posters and research seminar quite good in shaping the critical-mindedness, suspended judgment, respect for evidence, honesty, objectivity, and questioning attitude, as well as tolerance of uncertainty. In conclusion, the application of research-based teaching through the English for Biology courses could shape the students scientific attitudes. However, the consistency of the appearance of a scientific attitude in every stage of Biology-based RBT learning process need more intensive and critical assessment.

Population Cycles, Disease, and Networks of Ecological Knowledge.

PubMed

Jones, Susan D

2017-05-01

Wildlife populations in the northern reaches of the globe have long been observed to fluctuate or cycle periodically, with dramatic increases followed by catastrophic crashes. Focusing on the early work of Charles S. Elton, this article analyzes how investigations into population cycles shaped the development of Anglo-American animal ecology during the 1920s-1930s. Population cycling revealed patterns that challenged ideas about the "balance" of nature; stimulated efforts to quantify population data; and brought animal ecology into conversation with intellectual debates about natural selection. Elton used the problem of understanding wildlife population cycles to explore a central tension in ecological thought: the relative influences of local conditions (food supply, predation) and universal forces (such as climate change and natural selection) in regulating wild animal populations. He also sought patronage and built research practices and the influential Bureau of Animal Population around questions of population regulation during the 1930s. Focusing on disease as a local population regulator that could interact with global climatic influences, Elton facilitated an interdisciplinary and population-based approach in early animal ecology. Elton created a network of epidemiologists, conservationists, pathologists and mathematicians, who contributed to population cycle research. I argue that, although these people often remained peripheral to ecology, their ideas shaped the young discipline. Particularly important were the concepts of abundance, density, and disease; and the interactions between these factors and natural selection. However, Elton's reliance on density dependence unwittingly helped set up conditions conducive to the development of controversies in animal ecology in later years. While ecologists did not come to consensus on the ultimate causes of population cycles, this phenomenon was an important early catalyst for the development of theory and practice in animal ecology.

Does Medical School Training Relate to Practice? Evidence from Big Data.

Feldman, Keith; Chawla, Nitesh V

2015-06-01

On April 2nd, 2014, the Department of Health and Human Services (HHS) announced a historic policy in its effort to increase the transparency in the American healthcare system. The Center for Medicare and Medicaid Service (CMS) would publicly release a dataset containing information about the types of Medicare services, requested charges, and payments issued by providers across the country. In its release, HHS stated that the data would shed light on "Medicare fraud, waste, and abuse." While this is most certainly true, we believe that it can provide so much more. Beyond the purely financial aspects of procedure charges and payments, the procedures themselves may provide us with additional information, not only about the Medicare population, but also about the physicians themselves. The procedures a physician performs are for the most part not novel, but rather recommended, observed, and studied. However, whether a physician decides on advocating a procedure is somewhat discretionary. Some patients require a clear course of action, while others may benefit from a variety of options. This article poses the following question: How does a physician's past experience in medical school shape his or her practicing decisions? This article aims to open the analysis into how data, such as the CMS Medicare release, can help further our understanding of knowledge transfer and how experiences during education can shape a physician's decision's over the course of his or her career. This work begins with an evaluation into similarities between medical school charges, procedures, and payments. It then details how schools' procedure choices may link them in other, more interesting ways. Finally, the article includes a geographic analysis of how medical school procedure payments and charges are distributed nationally, highlighting potential deviations.

Healthcare quality and safety: a review of policy, practice and research.

Waring, Justin; Allen, Davina; Braithwaite, Jeffrey; Sandall, Jane

Over the last two decades healthcare quality and safety have risen to the fore of health policy and research. This has largely been informed by theoretical and empirical ideas found in the fields of ergonomics and human factors. These have enabled significant advances in our understanding and management of quality and safety. However, a parallel and at time neglected sociological literature on clinical quality and safety is presented as offering additional, complementary, and at times critical insights on the problems of quality and safety. This review explores the development and contributions of both the mainstream and more sociological approaches to safety. It shows that where mainstream approaches often focus on the influence of human and local environment factors in shaping quality, a sociological perspective can deepen knowledge of the wider social, cultural and political factors that contextualise the clinical micro-system. It suggests these different perspectives can easily complement one another, offering a more developed and layered understanding of quality and safety. It also suggests that the sociological literature can bring to light important questions about the limits of the more mainstream approaches and ask critical questions about the role of social inequality, power and control in the framing of quality and safety. © 2015 Foundation for the Sociology of Health & Illness.

Is international agricultural research a global public good? The case of rice biofortification.

PubMed

Brooks, Sally

2011-01-01

The status of international agricultural research as a global public good (GPG) has been widely accepted since the Green Revolution of the 1960s and 1970s. While the term was not used at the time of its creation, the Consultative Group on International Agricultural Research (CGIAR) system that evolved at that time has been described as a 'prime example of the promise, performance and perils of an international approach to providing GPGs'. Contemporary literature on international agricultural research as a GPG tends to support this view and focuses on how to operationalize the concept. This paper adopts a different starting point and questions this conceptualization of the CGIAR and its outputs. It questions the appropriateness of such a 'neutral' concept to a system born of the imperatives of Cold War geopolitics, and shaped by a history of attempts to secure its relevance in a changing world. This paper draws on a multi-sited, ethnographic study of a research effort highlighted by the CGIAR as an exemplar of GPG-oriented research. Behind the ubiquitous language of GPGs, 'partnership' and 'consensus', however, new forms of exclusion and restriction are emerging within everyday practice, reproducing North-South inequalities and undermining the ability of these programmes to respond to the needs of projected beneficiaries.

Gender Affirmation and Body Modification Among Transgender Persons in Bogotá, Colombia.

Aguayo-Romero, Rodrigo A; Reisen, Carol A; Zea, Maria Cecilia; Bianchi, Fernanda T; Poppen, Paul J

This paper examined structural, social, and personal characteristics that shape the processes of gender affirmation and body modification among transgender persons (assigned male at birth) in Bogotá, Colombia. Qualitative data from life-history interviews (N=14) and a focus group (N=11) explored research questions concerning the ways in which the internal psychological and external contextual processes influence individuals' decisions and behaviors concerning hormonal treatment, injections, or surgery. Research questions concerning practices and consequences of treatment performed without medical supervision were addressed through qualitative data, as well as quantitative data from 58 transgender participants. Findings indicated variation in ways participants conceptualized gender (e.g., binary or fluid), but an increased feminine presentation was a strong personal desire expressed by many and often encouraged by romantic partners and transgender friends. Transgender individuals within participants' social networks were frequently instrumental not only in providing information about hormones and contouring injections, but also in carrying out procedures-sometimes with negative consequences. Body modification procedures occurred primarily outside the health care system, due to limited access to or awareness of medical care, societal stigma, social norms within the transgender community, and personal decision-making. Public health approaches to protect the health of transgender persons undergoing body modification were suggested.

Building qualitative study design using nursing's disciplinary epistemology.

To discuss the implications of drawing on core nursing knowledge as theoretical scaffolding for qualitative nursing enquiry. Although nurse scholars have been using qualitative methods for decades, much of their methodological direction derives from conventional approaches developed for answering questions in the social sciences. The quality of available knowledge to inform practice can be enhanced through the selection of study design options informed by an appreciation for the nature of nursing knowledge. Discussion paper. Drawing on the body of extant literature dealing with nursing's theoretical and qualitative research traditions, we consider contextual factors that have shaped the application of qualitative research approaches in nursing, including prior attempts to align method with the structure and form of disciplinary knowledge. On this basis, we critically reflect on design considerations that would follow logically from core features associated with a nursing epistemology. The substantive knowledge used by nurses to inform their practice includes both aspects developed at the level of the general and also that which pertains to application in the unique context of the particular. It must be contextually relevant to a fluid and dynamic healthcare environment and adaptable to distinctive patient conditions. Finally, it must align with nursing's moral mandate and action imperative. Qualitative research design components informed by nursing's disciplinary epistemology will help ensure a logical line of reasoning in our enquiries that remains true to the nature and structure of practice knowledge. © 2015 John Wiley & Sons Ltd.

Cultural context and a critical approach to eliminating health disparities.

PubMed

Griffith, Derek M; Johnson, Jonetta; Ellis, Katrina R; Schulz, Amy Jo

2010-01-01

The science of eliminating racial health disparities requires a clear understanding of the underlying social processes that drive persistent differences in health outcomes by self-identified race. Understanding these social processes requires analysis of cultural notions of race as these are instantiated in institutional policies and practices that ultimately contribute to health disparities. Racism provides a useful framework for understanding how social, political and economic factors directly and indirectly influence health outcomes. While it is important to capture how individuals are influenced by their psychological experience of prejudice and discrimination, racism is more than an intrapersonal or interpersonal variable. Considerable attention has focused on race-based residential segregation and other forms of institutional racism but less focus has been placed on how cultural values, frameworks and meanings shape institutional policies and practices. In this article, we highlight the intersection of cultural and institutional racism as a critical mechanism through which racial inequities in social determinants of health not only develop but persist. This distinction highlights and helps to explain processes and structures that contribute to racial disparities persisting across time and outcomes. Using two historical examples, the National Negro Health Movement and hospital desegregation during the Civil Rights Era, we identify key questions that an analysis of cultural racism might add to the more common focus on overt policy decisions and practices.

Mainstreaming conservation agriculture in Malawi: Knowledge gaps and institutional barriers.

2017-06-15

Conservation agriculture (CA) practices of reduced soil tillage, permanent organic soil coverage and intercropping/crop rotation, are being advocated globally, based on perceived benefits for crop yields, soil carbon storage, weed suppression, reduced soil erosion and improved soil water retention. However, some have questioned their efficacy due to uncertainty around the performance and trade-offs associated with CA practices, and their compatibility with the diverse livelihood strategies and varied agro-ecological conditions across African smallholder systems. This paper assesses the role of key institutions in Malawi in shaping pathways towards more sustainable land management based on CA by outlining their impact on national policy-making and the design and implementation of agricultural development projects. It draws on interviews at national, district and project levels and a multi-stakeholder workshop that mapped the institutional landscape of decision-making for agricultural land management practices. Findings identify knowledge gaps and institutional barriers that influence land management decision-making and constrain CA uptake. We use our findings to set out an integrated roadmap of research needs and policy options aimed at supporting CA as a route to enhanced sustainable land management in Malawi. Findings offer lessons that can inform design, planning and implementation of CA projects, and identify the multi-level institutional support structures required for mainstreaming sustainable land management in sub-Saharan Africa.

Accomplishing professional jurisdiction in intensive care: An ethnographic study of three units.

Xyrichis, Andreas; Lowton, Karen; Rafferty, Anne Marie

2017-05-01

This paper reports an ethnographic study examining health professional jurisdictions within three intensive care units (ICUs) in order to draw out the social processes through which ICU clinicians organised and delivered life-saving care to critically ill patients. Data collection consisted of 240 h observation of actual practice and 27 interviews with health professionals. The research was conducted against a backdrop of international political and public pressure for national healthcare systems to deliver safe, quality and efficient healthcare. As in many Western health systems, for the English Department of Health the key to containing these challenges was a reconfiguration of responsibilities for clinicians in order to break down professional boundaries and encourage greater interprofessional working under the guise of workforce modernisation. In this paper, through the analysis of health professional interaction, we examine the properties and conditions under which professional jurisdiction was negotiated and accomplished in day-to-day ICU practice. We discuss how staff seniority influenced the nature of professional interaction and how jurisdictional boundaries were reproduced and reconfigured under conditions of routine and urgent work. Consequently, we question theorisation that treats individual professions as homogenous groups and overlooks fluctuation in the flow and intensity of work; and conclude that in ICU, urgency and seniority have a part to play in shaping jurisdictional boundaries at the level of day-to-day practice.

The effect of different levels of constructive teaching practices on teacher question asking behaviors

NASA Astrophysics Data System (ADS)

Erdogan, Ibrahim

The purposes of the study were: (1) to examine the effectiveness of the Iowa Chautauqua Professional Development Program (ICPDP) in moving elementary science teachers toward the use of more constructive teaching practices and (2) to investigate the effectiveness of different levels of teaching practices, especially in terms of a sample of teachers achieving "expert" state at the end of program compared with some attaining only with "competent" level. The variables considered were their perceptions of their own classroom practices, stated philosophy of teaching and learning, and their actual classroom practices and question asking behaviors observed via videotape recording. Structured questionnaires, focus group interviews, teacher reflections, and examination of lesson modules were used to collect data from thirty-three K-5 in-service teachers who were involved in a one-year ICPDP. Qualitative and quantitative analyses of data revealed that: (1) Teacher perceptions regarding their teaching and learning, and their actual teaching practices in classroom in terms of constructivist approaches were significantly changed after participation in the ICPDP. (2) Teacher perceptions of their classroom practices and stated philosophies of teaching and learning have a great affect on their actual practices that can be observed. (3) Teacher stated philosophies of teaching and learning significantly influence the quantity and quality of their use of questions in their classrooms. (4) The "expert" teachers accept students' alternative answers and deliberately ask high cognitive level questions that enable students to think critically and to guide them based on what the students are thinking. Alternatively, the "competent" teachers do not follow student responses and used questions which do not help students to understand their current level of understanding nor encourage students to reflect on their own thinking. (5) The role of "expert" teacher is more geared toward challenging student ideas stimulated by questions and then allowing students to build their understandings that are affected by the discussion. "Competent" teachers, on the other hand, exhibit a more transmissive approach that lead students to an end that has been previously determined. Such teaching does little to persuade students to use their own thinking.

Diseases, patients and the epistemology of practice: mapping the borders of health, medicine and care.

2015-06-01

Last year saw the 20th anniversary edition of JECP, and in the introduction to the philosophy section of that landmark edition, we posed the question: apart from ethics, what is the role of philosophy 'at the bedside'? The purpose of this question was not to downplay the significance of ethics to clinical practice. Rather, we raised it as part of a broader argument to the effect that ethical questions - about what we should do in any given situation - are embedded within whole understandings of the situation, inseparable from our beliefs about what is the case (metaphysics), what it is that we feel we can claim to know (epistemology), as well as the meaning we ascribe to different aspects of the situation or to our perception of it. Philosophy concerns fundamental questions: it is a discipline requiring us to examine the underlying assumptions we bring with us to our thinking about practical problems. Traditional academic philosophers divide their discipline into distinct areas that typically include logic: questions about meaning, truth and validity; ontology: questions about the nature of reality, what exists; epistemology: concerning knowledge; and ethics: how we should live and practice, the nature of value. Any credible attempt to analyse clinical reasoning will require us to think carefully about these types of question and the relationships between them, as they influence our thinking about specific situations and problems. So, the answers to the question we posed, about the role of philosophy at the bedside, are numerous and diverse, and that diversity is illustrated in the contributions to this thematic edition. © 2015 John Wiley & Sons, Ltd.

Shape-controlled synthesis of nanocarbons through direct conversion of carbon dioxide

Zhang, Haitao; Zhang, Xiong; Sun, Xianzhong; Ma, Yanwei

2013-12-01

Morphology control of carbon-based nanomaterials (nanocarbons) is critical to practical applications because their physical and chemical properties are highly shape-dependent. The discovery of novel shaped nanocarbons stimulates new development in carbon science and technology. Based on direct reaction of CO2 with Mg metal, we achieved controlled synthesis of several different types of nanocarbons including mesoporous graphene, carbon nanotubes, and hollow carbon nanoboxes. The last one, to our knowledge, has not been previously reported to this date. The method described here allows effective control of the shape and dimensions of nanocarbons through manipulation of reaction temperature. The formation mechanism of nanocarbons is proposed. As a proof of concept, the synthesized nanocarbons are used for electrodes in symmetrical supercapacitors, which exhibit high capacitance and good cycling stability. The reported protocols are instructive to production of nanocarbons with controlled shape and dimensions which are much desirable for many practical applications.

Diplomates in the American Board of Internal Medicine (ABIM) Maintenance of Certification (MOC) program satisfy the self-evaluation of medical knowledge requirement by completing open-book multiple-choice exams. However, this method remains unlikely to affect practice change and often covers content areas not relevant to diplomates' practices. We developed and evaluated an Internet-based point of care (POC) learning portfolio to serve as an alternative. Participants enter information about their clinical questions, including characteristics, information pursuit, application, and practice change. After documenting 20 questions, they reflect upon a summary report and write commitment-to-change statements about their learning strategies. They can link to help screens and medical information resources. We report on the beta test evaluation of the module, completed by 23 internists and 4 internal medicine residents. Participants found the instructions clear and navigated the module without difficulty. The majority preferred the POC portfolio to multiple-choice examinations, citing greater relevance to their practice, guidance in expanding their palette of information resources, opportunity to reflect on their learning needs, and "credit" for self-directed learning related to their patients. Participants entered a total of 543 clinical questions, of which 250 (46%) resulted in a planned practice change. After completing the module, 14 of 27 (52%) participants committed to at least 1 change in their POC learning strategies. Internists found the portfolio valuable, preferred it to multiple-choice examinations, often changed their practice after pursuing clinical questions, and productively reflected on their learning strategies. The ABIM will offer this portfolio as an elective option in MOC.

Recommended Screening Practices for Launch Collision Aviodance

NASA Technical Reports Server (NTRS)

Beaver, Brian A.; Hametz, Mark E.; Ollivierre, Jarmaine C.; Newman, Lauri K.; Hejduk, Matthew D.

2015-01-01

The objective of this document is to assess the value of launch collision avoidance (COLA) practices and provide recommendations regarding its implementation for NASA robotic missions. The scope of this effort is limited to launch COLA screens against catalog objects that are either spacecraft or debris. No modifications to manned safety COLA practices are considered in this effort. An assessment of the value of launch COLA can be broken down into two fundamental questions: 1) Does collision during launch represent a significant risk to either the payload being launched or the space environment? 2) Can launch collision mitigation be performed in a manner that provides meaningful risk reduction at an acceptable level of operational impact? While it has been possible to piece together partial answers to these questions for some time, the first attempt to comprehensively address them is documented in reference (a), Launch COLA Operations: an Examination of Data Products, Procedures, and Thresholds, Revision A. This report is the product of an extensive study that addressed fundamental technical questions surrounding launch collision avoidance analysis and practice. The results provided in reference (a) will be cited throughout this document as these two questions are addressed. The premise of this assessment is that in order to conclude that launch COLA is a value-added activity, the answer to both of these questions must be affirmative. A "no" answer to either of these questions points toward the conclusion that launch COLA provides little or no risk mitigation benefit. The remainder of this assessment will focus on addressing these two questions.

Structured methods and striking moments: using question sequences in "living" ways.

PubMed

Lowe, Roger

2005-03-01

This article draws together two seemingly incompatible practices in social constructionist therapies: the use of structured questioning methods (associated with solution-focused and narrative therapies) and the poetic elaboration of "striking moments" (associated with conversational therapies). To what extent can we value and use both styles of practice? Beginning with practitioners' concerns about the use of structured question sequences, I explore possibilities for resituating these methods in different conceptual and metaphorical frames, selectively drawing on ideas from the philosophy of striking moments. The aim is not to reduce one therapeutic style to another, but to encourage the teaching and practice of structured methods in more creative, improvisational, and "living" ways.

Pore structure and function of synthetic nanopores with fixed charges: tip shape and rectification properties

NASA Astrophysics Data System (ADS)

Ramírez, Patricio; Apel, Pavel Yu; Cervera, Javier; Mafé, Salvador

2008-08-01

We present a complete theoretical study of the relationship between the structure (tip shape and dimensions) and function (selectivity and rectification) of asymmetric nanopores on the basis of previous experimental studies. The theoretical model uses a continuum approach based on the Nernst-Planck equations. According to our results, the nanopore transport properties, such as current-voltage (I-V) characteristics, conductance, rectification ratio, and selectivity, are dictated mainly by the shape of the pore tip (we have distinguished bullet-like, conical, trumpet-like, and hybrid shapes) and the concentration of pore surface charges. As a consequence, the nanopore performance in practical applications will depend not only on the base and tip openings but also on the pore shape. In particular, we show that the pore opening dimensions estimated from the pore conductance can be very different, depending on the pore shape assumed. The results obtained can also be of practical relevance for the design of nanopores, nanopipettes, and nanoelectrodes, where the electrical interactions between the charges attached to the nanostructure and the mobile charges confined in the reduced volume of the inside solution dictate the device performance in practical applications. Because single tracks are the elementary building blocks for nanoporous membranes, the understanding and control of their individual properties should also be crucial in protein separation, water desalination, and bio-molecule detection using arrays of identical nanopores.

Experiment M115: Special hematologic effects: Dynamic changes in red cell shape in response to the space-flight environment

NASA Technical Reports Server (NTRS)

Kimzey, S. L.; Burns, L. C.; Fischer, C. L.

1974-01-01

The significance of the transformations in red cell shape observed during the Skylab study must be considered relative to the limitation of man's participation in extended space flight missions. The results of this one study are not conclusive with respect to this question. Based on these examinations of red cells in normal, healthy men and based on other Skylab experiment data relative to the functional capacity of the red cells in vitro and the performance capacity of man as an integrated system, the changes observed would not appear to be the limiting factor in determining man's stay in space. However, the results of this experiment and the documented red cell mass loss during space flight raise serious questions at this time relative to the selection criteria utilized for passengers and crews of future space flights. Until the specific cause and impact of the red cell shape change on cell survival in vivo can be resolved, individuals with diagnosed hematologic abnormalities should not be considered as prime candidates for missions, especially those of longer duration.

Density functional theory study of the capacitance of single file ions in a narrow cylinder

DOE PAGES

Kong, Xian; Wu, Jianzhong; Henderson, Douglas

2014-11-14

In this paper, the differential capacitance of a model organic electrolyte in a cylindrical pore that is so narrow that the ions can form only a single file is studied by means of density functional theory (DFT). Kornyshev (2013), has studied this system and found the differential capacitance to have only a double hump shape (the so-called camel shape) whereas other geometries show this behavior only at low ionic concentrations that are typical for aqueous electrolytes. However, his calculation is rather approximate. In this DFT study we find that the double hump shape occurs only at low ionic concentrations. Atmore » high concentrations, the capacitance has only a single hump. Kornyshev considers a metallic cylinder and approximately includes the contributions of electrostatic images. Electrostatic images are not easily incorporated into DFT. In conclusion, images are not considered in this study and the question of whether Kornyshev’s result is due to his approximations or images cannot be answered. Simulations to answer this question are planned.« less

Mexican parents' and teachers' literacy perspectives and practices: construction of cultural capital.

Reese, Leslie; Arauz, Rebeca Mejía; Bazán, Antonio Ray

2012-01-01

This article examines the relationships among the literacy practices engaged in by first-grade children and parents at home and the ways in which these practices are communicated, shaped, and fostered by teachers and administrators in two different sociocultural environments in urban Mexico. The differences observed between the home literacy experiences of children in a working class and a middle class community included transgenerational communication of assumptions regarding literacy and schooling, as well as attitudes associated with the parents' own school experiences. Class-based expectations on the part of teachers not only shaped interactions with parents, but were also reflected in the way the national curriculum was delivered, with a greater emphasis on rote skills and traditional reading instruction in the working class community. The authors argue that the school plays a role in the co-production of cultural capital in the home through its shaping of some of the literacy practices that children and families undertake.

Feedback Control Systems Loop Shaping Design with Practical Considerations

NASA Technical Reports Server (NTRS)

Kopsakis, George

2007-01-01

This paper describes loop shaping control design in feedback control systems, primarily from a practical stand point that considers design specifications. Classical feedback control design theory, for linear systems where the plant transfer function is known, has been around for a long time. But it s still a challenge of how to translate the theory into practical and methodical design techniques that simultaneously satisfy a variety of performance requirements such as transient response, stability, and disturbance attenuation while taking into account the capabilities of the plant and its actuation system. This paper briefly addresses some relevant theory, first in layman s terms, so that it becomes easily understood and then it embarks into a practical and systematic design approach incorporating loop shaping design coupled with lead-lag control compensation design. The emphasis is in generating simple but rather powerful design techniques that will allow even designers with a layman s knowledge in controls to develop effective feedback control designs.

2016-01-01

Medical end-of-life practices are hotly debated in Canada, and data from other countries are used to support arguments. The objective of this pilot study was twofold: to adapt and validate a questionnaire designed to measure the prevalence of these practices in Canada and the underlying decision-making process, and to assess the feasibility of a nationally representative study. In phase 1, questionnaires from previous studies were adapted to the Canadian context through consultations with a multidisciplinary committee and based on a scoping review. The modified questionnaire was validated through cognitive interviews with 14 physicians from medical specialties associated with a higher probability of being involved with dying patients recruited by means of snowball sampling. In phase 2, we selected a stratified random sample of 300 Canadian physicians in active practice from a national medical directory and used the modified tailored method design for mail and Web surveys. There were 4 criteria for success: modified questions are clearly understood; response patterns for sensitive questions are similar to those for other questions; respondents are comparable to the overall sampling frame; and mean questionnaire completion time is less than 20 minutes. Phase 1: main modifications to the questionnaire were related to documentation of all other medical practices (including practices intended to prolong life) and a question on the proportionality of drugs used. The final questionnaire contained 45 questions in a booklet style. Phase 2: of the 280 physicians with valid addresses, 87 (31.1%) returned the questionnaire; 11 of the 87 declined to participate, for a response rate of 27.1% (n = 76). Most respondents (64 [84%]) completed the mail questionnaire. All the criteria for success were met. It is feasible to study medical end-of-life practices, even for practices that are currently illegal, including the intentional use of lethal drugs. Results from this pilot study support conducting a large national study, but additional strategies would be necessary to improve the response rate.

The right to health, health systems development and public health policy challenges in Chad.

PubMed

Azétsop, Jacquineau; Ochieng, Michael

2015-02-15

There is increasing consensus that the right to health can provide ethical, policy and practical groundings for health systems development. The goals of the right to health are congruent with those of health systems development, which are about strengthening health promotion organizations and actions so as to improve public health. The poor shape and performance of health systems in Chad question the extent of realization of the right to health. Due to its comprehensiveness and inclusiveness, the right to health has the potential of being an organizational and a normative backbone for public health policy and practice. It can then be understood and studied as an integral component of health systems development. This paper uses a secondary data analysis of existing documents by the Ministry of Public Health, Institut National de la Statistique, des Etudes Economiques et Démographiques (INSEED), the Ministry of Economy and Agence Française de Cooperation to analyze critically the shape and performance of health systems in Chad based on key concepts and components of the right to health contained in article 12 of the International Covenant on Economic, Social and Cultural Rights, and on General Comment 14. The non-realization of the right to health, even in a consistently progressive manner, raises concerns about the political commitment of state officials to public health, about the justice of social institutions in ensuring social well-being and about individual and public values that shape decision-making processes. Social justice, democratic rule, transparency, accountability and subsidiarity are important groundings for ensuring community participation in public affairs and for monitoring the performance of public institutions. The normative ideals of health systems development are essentially democratic in nature and are rooted in human rights and in ethical principles of human dignity, equality, non-discrimination and social justice. These ideals are grounded in an integrated vision of society as a place for multi-level interactions, where government plays its role by equitably providing institutions and services that ensure people's welfare. Inter-sectoral collaboration, which calls for a conceptual shift in health and public policy, can be instrumental in improving health systems through concerted efforts of various governmental institutions and civil society.

2006-03-01

The practice of e-learning in our department utilizing freeware without additional cost has been introduced: 1) Examinations and exercises are performed on the Web. Using the form-filling format of HTML, multiple-choice questions are asked. When the examinee submits the answers, the server will process the data using active server pages and send the result to the examinee with the score and explanations. So far, the students have given the Web examination (exercise) system a good evaluation. Concerning the effect of the explanations given in the Web exercises on the written test, some improvements were observed in the enumeration-type questions. On the other hand, no such improvements were clearly observed in the explanation-type questions, which require essential understanding of the principle. This suggests that effective utilization of the materials strongly depends on the students' eagerness to study. 2) To understand the chemical structures of body constituents, an exercise to draw structural formulae on the personal computer (PC) is performed. The students had difficulty in the fine control of arranging the whole shape of the formula, in addition to setting the format of characters such as super- and subscripts. In respect of understanding, they had significant difficulty in finding the structures and in distinguishing stereoisomers; however, the students had fun with the structure-drawing software and found it convenient to draw structures. These findings suggest that PC exercises will be attractive to students of the "PC generation", and thus helpful for the understanding of and training in data analysis in medical technology.

2014-07-01

Masturbation is a common sexual activity among people of all ages throughout life. It has been traditionally prohibited and judged as immoral and sinful by several religions. Although it is no longer perceived as a negative behavior, masturbation is often omitted in the diagnostic inquiry of patients with sexual problems. The aims of this study are to increase the awareness of clinicians to the importance of including questions regarding masturbatory habits in the process of sexual history taking, to analyze cases of male sexual dysfunction (SD) associated with unusual masturbatory practices, and to propose a practical tool for clinicians to diagnose and manage such problems. A clinical study of four cases that include a range of unusual masturbatory practices by young males who applied for sex therapy is described. An intervention plan involving specific questions in case history taking was devised. It was based on detailed understanding of each patient's masturbatory practice and its manifestation in his SD. Effects of identifying and altering masturbatory practices on sexual function. The four men described unusual and awkward masturbatory practices, each of which was associated with different kinds of SD. The unlearning of the masturbatory practices contributed notably to improvement of their sexual function. The four cases in this study indicate that the detailed questioning of masturbatory habits is crucial for a thorough assessment and adequate treatment of sexual problems in men. We propose specific questions on masturbatory behavior as well as a diagnostic and therapeutic flowchart for physicians and sex therapists to address those problems. © 2014 International Society for Sexual Medicine.

The shaping of information by visual metaphors.

PubMed

Ziemkiewicz, Caroline; Kosara, Robert

2008-01-01

The nature of an information visualization can be considered to lie in the visual metaphors it uses to structure information. The process of understanding a visualization therefore involves an interaction between these external visual metaphors and the user's internal knowledge representations. To investigate this claim, we conducted an experiment to test the effects of visual metaphor and verbal metaphor on the understanding of tree visualizations. Participants answered simple data comprehension questions while viewing either a treemap or a node-link diagram. Questions were worded to reflect a verbal metaphor that was either compatible or incompatible with the visualization a participant was using. The results (based on correctness and response time) suggest that the visual metaphor indeed affects how a user derives information from a visualization. Additionally, we found that the degree to which a user is affected by the metaphor is strongly correlated with the user's ability to answer task questions correctly. These findings are a first step towards illuminating how visual metaphors shape user understanding, and have significant implications for the evaluation, application, and theory of visualization.

2015-02-01

The United States Food and Drug Administration and the Department of Agriculture jointly published the "Guide to Minimize Microbial Food Safety Hazards for Fresh Fruits and Vegetables," which is used as a basis for Good Agricultural Practices (GAP) audits. To understand barriers to incorporation of GAP by Minnesota vegetable farmers, a mail survey completed in 2008 was validated with visits to a subset of the farms. This was done to determine the extent to which actual practices matched perceived practices. Two hundred forty-six producers completed the mail survey, and 27 participated in the on-farm survey. Over 75% of the on-farm survey respondents produced vegetables on 10 acres or less and had 10 or fewer employees. Of 14 questions, excellent agreement between on-farm interviews and mail survey responses was observed on two questions, four questions had poor or slight agreement, and eight questions had no agreement. Ninety-two percent of respondents by mail said "they took measures to keep animals and pests out of packing and storage buildings." However, with the on-site visit only 45% met this requirement. Similarly, 81% of respondents by mail said "measures were taken to reduce the risk of wild and/or domestic animals entering into fruit and vegetable growing areas." With direct observation, 70% of farms actually had taken measures to keep animals out of the growing areas. Additional, on-farm assessments were done regarding employee hygiene, training, presence of animals, water sources, and composting practices. This validation study demonstrated the challenge of creating nonleading and concise questions that are not open to broad interpretation from the respondents. If mail surveys are used to assess GAP, they should include open-ended questions and ranking systems to better assess farm practices. To provide the most accurate survey data for educational purposes or GAP audits, on-farm visits are recommended.

There has been little discussion in the plastic surgery literature regarding breast shape preferences among plastic surgeons, despite strong evidence that such aesthetic preferences are influenced by multiple factors. Much effort has been focused on delineating the objective criteria by which an "attractive" breast might be defined. This study aimed at providing a better understanding of the presence and significance of differences in personal aesthetic perception, and how these relate to a plastic surgeon's demographic, ethnic, and cultural background, as well as practice type (academic vs private). An interactive online survey was designed. Modifiable ranges of upper pole fullness and areola size were achieved via digital alteration, enabling participants to interactively change the shape of a model's breasts. The questionnaire was translated into multiple languages and sent to plastic surgeons worldwide. Demographic data were also collected. Analysis of variance was used to elucidate plastic surgeon's breast shape preferences in respect to sex and age, geographic and ethnic background, as well as practice type. The authors gathered 614 responses from 29 different countries. Significant differences regarding preferences for upper pole fullness, areola size in the natural breast, and areola size in the augmented breast were identified across surgeons from the different countries. Further, significant relationships regarding breast shape preferences were distilled between the age and sex of the surgeon, as well as the practice type. No differences were found in respect to the surgeons' self-reported ethnic background. Country of residence, age, and practice type significantly impact breast shape preferences of plastic surgeons. These findings have implications for both patients seeking and surgeons performing cosmetic and reconstructive breast surgery. In an increasingly global environment, cultural differences and international variability must be considered when defining and publishing new techniques and aesthetic outcomes. When both the plastic surgeon and the patient are able to adequately and effectively communicate their preferences regarding the shape and relations of the breast, they will be more successful at achieving satisfying results.

Reichler, G; Dalton, S

1998-02-01

To determine if chefs' and student chefs' attitudes, knowledge, and practices regarding healthful food preparation are consistent with the Dietary Guidelines for Americans. An analytical survey questionnaire was distributed to 4 chef groups. Sections 1 and 2 of the survey measured chefs' food science knowledge (13 questions) and likelihood of using food preparation practices (15 questions) necessary to meet the 1990 Dietary Guidelines for Americans. Section 3 (22 questions) measured chefs' attitudes toward nutrition in general, toward the importance of healthful food preparation practices, and toward the US Dietary Guidelines. Of 512 surveys distributed by mail, at culinary meetings, and in classes at 2 culinary schools, 447 (86%) were returned (158 from practicing chefs and 289 from student chefs). Practicing chefs included chef educators, foodservice chefs from a national corporation, and independent chef members of the American Culinary Federation of New York City. Descriptive statistics included frequencies, means, and standard deviations of survey items and of individual survey sections. Reliability and validity were determined using alpha coefficients and principal components analysis. Analysis of variance was used to examine differences in practice, attitudes, and knowledge among chef groups. Both practicing chefs and student chefs answered more than 70% of the food science questions correctly; independent chefs scored significantly lower than educator and corporate chefs. More than two thirds of the chefs and student chefs correctly responded to questions about the nutrient composition of food and how cooking affects the nutrient content of food. All chef groups were confused about fat and cholesterol in food and in the body. Few healthful food preparation practices were likely to be used by any chef group more than two thirds of the time, although the subscale of the attitude toward the importance of these practices was very positive. The majority of practicing chefs thought that customers do not care about the US Dietary Guidelines and nutrition; student chefs thought that customers do care. Both groups strongly agreed that, as chefs, they are responsible for the nutritional content of the food they prepared. Both chefs and student chefs are willing to learn about food science and recipe modification principles as they apply to healthful cooking practices. The opportunities are clear: Dietitians have the expertise to teach chefs healthful food preparation techniques, recipe modification, and food composition information.

Randomized controlled trials in evidence-based mental health care: getting the right answer to the right question.

The purpose of clinical research is to answer this question: Would a new treatment, when added to the existing range of treatment options available in practice, help patients? Randomized controlled trials (RCTs)--in particular, double-blind RCTs--have important methodological advantages over observational studies for addressing this question. These advantages, however, come at a price. RCTs compare treatments using a particular allocation rule for assigning patients to treatments (random assignment) that does not mimic real-world practice. "Favorable" results from an RCT indicating that a new treatment is superior to existing treatments are neither necessary nor sufficient for establishing a "yes" answer to the question posed above. Modeled on an experimental design, RCTs are expensive in time and money and must compare simple differences in treatments. Findings have a high internal validity but may not address the needs of the field, particularly where treatment is complex and rapidly evolving. Design of clinical research needs to take account of the way treatments are allocated in actual practice and include flexible designs to answer important questions most effectively.

During the last decades, sex and gender biases have been identified in various areas of biomedical and public health research, leading to compromised validity of research findings. As a response, methodological requirements were developed but these are rarely translated into research practice. The aim of this study is to provide good practice examples of sex/gender sensitive health research. We conducted a systematic search of research articles published in JECH between 2006 and 2014. An instrument was constructed to evaluate sex/gender sensitivity in four stages of the research process (background, study design, statistical analysis, discussion). In total, 37 articles covering diverse topics were included. Thereof, 22 were evaluated as good practice example in at least one stage; two articles achieved highest ratings across all stages. Good examples of the background referred to available knowledge on sex/gender differences and sex/gender informed theoretical frameworks. Related to the study design, good examples calculated sample sizes to be able to detect sex/gender differences, selected sex/gender sensitive outcome/exposure indicators, or chose different cut-off values for male and female participants. Good examples of statistical analyses used interaction terms with sex/gender or different shapes of the estimated relationship for men and women. Examples of good discussions interpreted their findings related to social and biological explanatory models or questioned the statistical methods used to detect sex/gender differences. The identified good practice examples may inspire researchers to critically reflect on the relevance of sex/gender issues of their studies and help them to translate methodological recommendations of sex/gender sensitivity into research practice.

State Wildlife Action Plans as Tools for Adapting to a Continuously Changing Climate

NASA Astrophysics Data System (ADS)

Metivier, D. W.; Yocum, H.; Ray, A. J.

2015-12-01

Public land management plans are potentially powerful policies for building sustainability and adaptive capacity. Land managers are recognizing the need to respond to numerous climate change impacts on natural and human systems. For the first time, in 2015, the federal government required each state to incorporate climate change into their State Wildlife Action Plans (SWAP) as a condition for funding. As important land management tools, SWAPs have the potential to guide state agencies in shaping and implementing practices for climate change adaptation. Intended to be revised every ten years, SWAPs can change as conditions and understanding of climate change evolves. This study asks what practices are states using to integrate climate change, and how does this vary between states? To answer this question, we conducted a broad analysis among seven states (CO, MT, NE, ND, SD, UT, WY) and a more in-depth analysis of four states (CO, ND, SD, WY). We use seven key factors that represent best practices for incorporating climate change identified in the literature. These best practices are species prioritization, key habitats, threats, monitoring, partnerships and participation, identification of management options, and implementation of management options. The in-depth analysis focuses on how states are using climate change information for specific habitats addressed in the plans. We find that states are integrating climate change in many different ways, showing varying degrees of sophistication and preparedness. We summarize different practices and highlight opportunities to improve the effectiveness of plans through: communication tools across state lines and stakeholders, explicit targeting of key habitats, enforcement and monitoring progress and success, and conducting vulnerability analyses that incorporate topics beyond climate and include other drivers, trajectories, and implications of historic and future land-use change.

The aim was to determine the differences in parents' perceptions of boys' and girls' body shapes and the explanations for the emphasis on body shape care of children. Subjects were low-income parents (n = 158) of preschoolers attending preschools in Kuala Lumpur, Malaysia. Parental perceptions of children's body shapes were assessed based on their rankings (scale of 1 to 7) of four attributes (ideal, healthy, fat and thin) for boy and girl figures. Parental responses to five questions on the importance of body shape were also obtained. Parental rankings of ideal and healthy body shapes were significantly lower for girls than boys (p < 0.001). However, mothers' and fathers' rankings of boys' and girls' body shapes were not significantly different. for both boys and girls, parental ratings for ideal body shape were significantly lower than for healthy body shape (p < 0.001). The majority of parents indicated that children's body shape is important for their future health, self enhancement, social interaction and career. With the increasing prevalence of body dissatisfaction among Malaysian children, these findings contribute to the understanding of parental roles in the development of body image and perhaps, in the etiology of body dissatisfaction among children.

Van Eyndhoven, Lisa; Chussid, Steven; Yoon, Richard K

2015-11-01

The aim of this cross-sectional study was to determine pediatric dentists' attitudes about speech evaluation in the dental setting and assess their knowledge of speech development and pathology. In October 2013, members of the American Academy of Pediatric Dentistry were invited to participate in an electronic questionnaire. Categories of questions were demographics, attitudes and confidence in speech pathology, and theoretical and practical knowledge of speech development and speech pathology. Theoretical knowledge was assessed using questions about phonetics and speech milestones. Practical knowledge was determined with three 30-second interview-style video clips. A total of 539 responses were received for a response rate of 10.4%. The majority of respondents reported feeling that speech evaluation should be part of the pediatric dental visit (72.8%) and felt confident in their ability to detect speech issues (73.2%). However, they did poorly on the theoretical knowledge questions (41.9%) as well as the practical knowledge questions (8.5%). There was a statistically significant difference in theoretical score between gender and type of occupation (p<0.05). This difference was not observed when examining practical knowledge. This study suggests that although pediatric dentists are in an ideal position to aid in the detection of speech issues, they currently have insufficient training and knowledge to do so.

Perceptual organization of shape, color, shade, and lighting in visual and pictorial objects

PubMed Central

Pinna, Baingio

2012-01-01

The main questions we asked in this work are the following: Where are representations of shape, color, depth, and lighting mostly located? Does their formation take time to develop? How do they contribute to determining and defining a visual object, and how do they differ? How do visual artists use them to create objects and scenes? Is the way artists use them related to the way we perceive them? To answer these questions, we studied the microgenetic development of the object perception and formation. Our hypothesis is that the main object properties are extracted in sequential order and in the same order that these roles are also used by artists and children of different age to paint objects. The results supported the microgenesis of object formation according to the following sequence: contours, color, shading, and lighting. PMID:23145283

Morphological evolution through integration: a quantitative study of cranial integration in Homo, Pan, Gorilla and Pongo.

Morphological integration refers to coordinated variation among traits that are closely related in development and/or function. Patterns of integration can offer important insight into the structural relationship between phenotypic units, providing a framework to address questions about phenotypic evolvability and constraints. Integrative features of the primate cranium have recently become a popular subject of study. However, an important question that still remains under-investigated is: what is the pattern of cranial shape integration among closely related hominoids? To address this question, we conducted a Procrustes-based geometric morphometrics study to quantify and analyze shape covariation patterns between different cranial regions in Homo, Pan, Gorilla and Pongo. A total of fifty-six 3D landmarks were collected on 407 adult individuals. We then sub-divided the landmarks corresponding to cranial units as outlined in the 'functional matrix hypothesis.' Sub-dividing the cranium in this manner allowed us to explore patterns of covariation between the face, basicranium and cranial vault, using the two-block partial least squares approach. Our results suggest that integrated shape changes in the hominoid cranium are complex, but that the overall pattern of integration is similar among human and non-human apes. Thus, despite having very distinct morphologies the way in which the face, basicranium and cranial vault covary is shared among these taxa. These results imply that the pattern of cranial integration among hominoids is conserved. Copyright © 2011 Elsevier Ltd. All rights reserved.

Internal controls are the methods and procedures used by any business to prevent or detect errors, safeguard assets (especially cash) from being misappropriated, and encourage staff adherence to prescribed managerial policies. Internal controls in a medical practice differ depending on the size and complexity of the practice. The key, however, is that they prevent or detect errors and efforts to circumvent the established policies and procedures of the organization. How good are the internal controls in your group practice? This article identifies ten questions you should use to evaluate your risk of asset misappropriation.

Archibald, Douglas; Liddy, Clare; Lochnan, Heather A; Hendry, Paul J; Keely, Erin J

2018-01-01

Continuing professional development (CPD) offerings should address the educational needs of health care providers. Innovative programs, such as electronic consultations (eConsults), provide unique educational opportunities for practice-based needs assessment. The purpose of this study is to assess whether CPD offerings match the needs of physicians by coding and comparing session content to clinical questions asked through eConsults. This study analyzes questions asked by primary care providers between July 2011 and January 2015 using a service that allows specialists to provide consultation over a secure web-based server. The content of these questions was compared with the CPD courses offered in the area in which these primary care providers are practicing over a similar period (2012-2014). The clinical questions were categorized by the content area. The percentage of questions asked about each content area was calculated for each of the 12 specialties consulted. CPD course offerings were categorized using the same list of content areas. Percentage of minutes dedicated to each content area was calculated for each specialty. The percentage of questions asked and the percentage of CPD course minutes for each content area were compared. There were numerous congruencies and discrepancies between the proportion of questions asked about a given content area and the CPD minutes dedicated to it. Traditional needs assessment may underestimate the need to address topics that are frequently the subject of eConsults. Planners should recognize eConsult questions as a valuable source of practice-associated challenges that can identify professional development needs of physicians.

Restoring warped document images through 3D shape modeling.

PubMed

Tan, Chew Lim; Zhang, Li; Zhang, Zheng; Xia, Tao

2006-02-01

Scanning a document page from a thick bound volume often results in two kinds of distortions in the scanned image, i.e., shade along the "spine" of the book and warping in the shade area. In this paper, we propose an efficient restoration method based on the discovery of the 3D shape of a book surface from the shading information in a scanned document image. From a technical point of view, this shape from shading (SFS) problem in real-world environments is characterized by 1) a proximal and moving light source, 2) Lambertian reflection, 3) nonuniform albedo distribution, and 4) document skew. Taking all these factors into account, we first build practical models (consisting of a 3D geometric model and a 3D optical model) for the practical scanning conditions to reconstruct the 3D shape of the book surface. We next restore the scanned document image using this shape based on deshading and dewarping models. Finally, we evaluate the restoration results by comparing our estimated surface shape with the real shape as well as the OCR performance on original and restored document images. The results show that the geometric and photometric distortions are mostly removed and the OCR results are improved markedly.

People-centred science: strengthening the practice of health policy and systems research

PubMed Central

2014-01-01

Health policy and systems research (HPSR) is a transdisciplinary field of global importance, with its own emerging standards for creating, evaluating, and utilizing knowledge, and distinguished by a particular orientation towards influencing policy and wider action to strengthen health systems. In this commentary, we argue that the ability of the HPSR field to influence real world change hinges on its becoming more people-centred. We see people-centredness as recognizing the field of enquiry as one of social construction, requiring those conducting HPSR to locate their own position in the system, and conduct and publish research in a manner that foregrounds human agency attributes and values, and is acutely attentive to policy context. Change occurs at many layers of a health system, shaped by social, political, and economic forces, and brought about by different groups of people who make up the system, including service users and communities. The seeds of transformative practice in HPSR lie in amplifying the breadth and depth of dialogue across health system actors in the conduct of research – recognizing that these actors are all generators, sources, and users of knowledge about the system. While building such a dialogic practice, those conducting HPSR must strive to protect the autonomy and integrity of their ideas and actions, and also clearly explain their own positions and the value-basis of their work. We conclude with a set of questions that health policy and systems researchers may wish to consider in making their practice more people-centred, and hence more oriented toward real-world change.

2017-03-01

To examine the culturally embedded nature of religious practices, we conducted a mixed-methods study in which Muslim American adolescents described how and why their religious practices had changed in recent years (see Etengoff & Daiute, 2013, J. Adolesc. Res., 28, 690). Participants included 201 Muslim adolescents (ages 13-19) from predominantly immigrant families; all were contestants in a Muslim Inter-Scholastic Tournament regional competition. Participants completed surveys including an item regarding whether their religious practices had changed, and for those who answered affirmatively, open-ended questions about the change. Additional measures assessed ethnic identity and perceived discrimination. As hypothesized, the 60% of participants who reported a change in religious practices described this shift as a response to new contexts, people, and religious knowledge. Those who reported a change also reported higher levels of ethnic identity exploration and perceived discrimination. Overall, Muslim American adolescents' descriptions portrayed religious practices as developing through reciprocal interactions with culture. More generally, participants' descriptions point to the viability of a model in which religious practices change and in turn are changed by cultural contexts. Statement of contribution What is already known on this subject? Religious development is viewed as taking place in relational systems with reciprocity between individuals and surrounding contexts. Variations in contexts predict variations in religious development, but mechanisms of development are not well understood. Muslim Americans, including adolescents, show high levels of religious involvement and experience unique cultural and religious contexts. Muslim American emerging adults describe their religious practices as responsive to sociocultural contexts. What does the study add? This study focuses on Muslim American adolescents, a group that has received little research attention, especially in regard to religious development. Participants reported a wide array of changes in religious practices, and they described these changes as responses to social and cultural influences. Participants' descriptions of changing practices can be understood through a Vygotskian framework in which religious practices are cultural tools that both respond to and shape surrounding cultural contexts. © 2017 The British Psychological Society.

The kids at Hamilton Elementary School: Purposes and practices for co-opting science

NASA Astrophysics Data System (ADS)

Ortiz, Loaiza

The purpose of this study was to explore youth's purposes and motivations for engaging in science through the lens of science practices. The construct of science practices allowed me to see science in youths' lives in a holistic way, shaped by social, political, historical, economic and cultural forces. The framework for understanding urban youths' science practices is grounded in the intersections of critical and feminist theory, sociocultural learning theories, especially as applied in research in urban science education, and recent work in critical literacy studies. As I explored the answers to my research questions---(1) When 5th grade youth, living in predominantly Latino communities struggling with urban poverty, engage in science how and why do they co-opt science in ways that result in changes in participation in science? (2) What are the science practices that facilitate youths' coopting of science? And how are those practices framed by context (school, out-of-school), content (LiFE curriculum), and funds of knowledge? (3) In what ways are science practices expressions of youths' scientific literacy? And (4) In what ways do youth use science practices as tools for expressing identities and agency?---I engaged in feminist ethnography with embedded case studies. Data were collected in 2004 in school and in out of school settings. I recorded numerous informal conversations, interviews, and observations both during after-school and students' regular science and non-science classes. Findings describe how and why students co-opted science for purposes that make sense for their lives. These purposes included gaining and activating resources, building and maintaining social relationships, bridging home and school knowledge, positioning themselves with authority, and constructing science identities. Findings also explored what practices facilitated youth's co-opting of science. I highlighted three practices: making ideas public, storytelling and prioritizing and using evidence. Finally, I present an in-depth analysis of the science practice of storytelling. Analysis revealed that students engaged in storytelling to facilitate co-opting of science by: allowing them to change the discourse of the science classroom, to seek legitimacy, and to position themselves with authority. I end with implications for urban science education, teacher education and for future research.

The Canadian Cancer Society and the National Cancer Institute of Canada have charged their Centre for Behavioral Research and Program Evaluation with contributing to the development of the country’s systemic capacity to link research, policy, and practice related to population-level interventions. Local data collection and feedback systems are integral to this capacity. Canada’s School Health Action Planning and Evaluation System (SHAPES) allows data to be collected from all of a school’s students, and these data are used to produce computer-generated school “health profiles.” SHAPES is being used for intervention planning, evaluation, surveillance, and research across Canada. Strong demand and multipartner investment suggest that SHAPES is adding value in all of these domains.

A field-shaping multi-well avalanche detector for direct conversion amorphous selenium

DOE Office of Scientific and Technical Information (OSTI.GOV)

Goldan, A. H.; Zhao, W.

2013-01-15

Purpose: A practical detector structure is proposed to achieve stable avalanche multiplication gain in direct-conversion amorphous selenium radiation detectors. Methods: The detector structure is referred to as a field-shaping multi-well avalanche detector. Stable avalanche multiplication gain is achieved by eliminating field hot spots using high-density avalanche wells with insulated walls and field-shaping inside each well. Results: The authors demonstrate the impact of high-density insulated wells and field-shaping to eliminate the formation of both field hot spots in the avalanche region and high fields at the metal-semiconductor interface. Results show a semi-Gaussian field distribution inside each well using the field-shaping electrodes,more » and the electric field at the metal-semiconductor interface can be one order-of-magnitude lower than the peak value where avalanche occurs. Conclusions: This is the first attempt to design a practical direct-conversion amorphous selenium detector with avalanche gain.« less

The 'Clinical Guidelines for Obstetrical Practice, 2011 edition' were revised and published as a 2014 edition (in Japanese) in April 2014 by the Japan Society of Obstetrics and Gynecology and the Japan Association of Obstetricians and Gynecologists. The aims of this publication include the determination of current standard care practices for pregnant women in Japan, the widespread use of standard care practices, the enhancement of safety in obstetrical practice, the reduction of burdens associated with medico-legal and medico-economical problems, and a better understanding between pregnant women and maternity-service providers. The number of Clinical Questions and Answers items increased from 87 in the 2011 edition to 104 in the 2014 edition. The Japanese 2014 version included a Discussion, a List of References, and some Tables and Figures following the Answers to the 104 Clinical Questions; these additional sections covered common problems and questions encountered in obstetrical practice, helping Japanese readers to achieve a comprehensive understanding. Each answer with a recommendation level of A, B or C was prepared based principally on 'evidence' or a consensus among Japanese obstetricians in situations where 'evidence' was weak or lacking. Answers with a recommendation level of A or B represent current standard care practices in Japan. All 104 Clinical Questions and Answers items, with the omission of the Discussion, List of References, and Tables and Figures, are presented herein to promote a better understanding among English readers of the current standard care practices for pregnant women in Japan. © 2014 The Authors.

To identify and prioritize research questions of concern to the practice of pediatric critical care nursing practice. One-day consensus conference. By using a conceptual framework by Benner et al describing domains of practice in critical care nursing, nine international nurse researchers presented state-of-the-art lectures. Each identified knowledge gaps in their assigned practice domain and then poised three research questions to fill that gap. Then, meeting participants prioritized the proposed research questions using an interactive multivoting process. Seventh World Congress on Pediatric Intensive and Critical Care in Istanbul, Turkey. Pediatric critical care nurses and nurse scientists attending the open consensus meeting. Systematic review, gap analysis, and interactive multivoting. The participants prioritized 27 nursing research questions in nine content domains. The top four research questions were 1) identifying nursing interventions that directly impact the child and family's experience during the withdrawal of life support, 2) evaluating the long-term psychosocial impact of a child's critical illness on family outcomes, 3) articulating core nursing competencies that prevent unstable situations from deteriorating into crises, and 4) describing the level of nursing education and experience in pediatric critical care that has a protective effect on the mortality and morbidity of critically ill children. The consensus meeting was effective in organizing pediatric critical care nursing knowledge, identifying knowledge gaps and in prioritizing nursing research initiatives that could be used to advance nursing science across world regions.

Poorolajal, J; Cheraghi, P; Irani, A Doosti; Cheraghi, Z; Mirfakhraei, M

2012-01-01

Background This study was conducted to develop a questionnaire in order to evaluate knowledge, attitude and practice (KAP) of the faculty members and students toward plagiarism. Methods: A KAP study was conducted from June to October 2011 enrolling 390 volunteers anonymously (response rate 96%). The questionnaire included the following four parts: (a) general characteristics like gender, academic degree and education level; (b) nine questions regarding knowledge (Min=0, Max=9); (c) nine questions regarding attitude (Min=9, Max=27); and (d) eight questions regarding practice (Min=0, Max=8). A pilot study was conducted to assess reliability of the questions regarding knowledge and attitude. Cronbach’s alpha coefficient for the knowledge and attitude questions was 0.70 and 0.74 respectively. Results: The overall prevalence of at least once plagiarism commission was 38% (SD=0.035). The overall mean score of knowledge, attitude and practice was 5.94 (SD=1.66), 24.12 (SD=2.99), and 0.66 (SD=1.15) respectively. Knowledge of plagiarism was significantly higher among higher academic degrees and females. Their negative attitude toward plagiarism was stronger too. No statistically significant difference regarding plagiarism commission was observed among different academic degrees in both sexes. According to linear regression analysis, plagiarism commission decreased 13% per one unit increase in score of knowledge (P=0.005) and 16% per one unit increase in score of attitude (P<0.001). Conclusions: This knowledge, attitude, and practice (KAP) questionnaire was developed as a standard tool in order to assess perception of subjects toward plagiarism and to estimate the prevalence and the type of plagiarism commission.

Phenomenology based multiscale models as tools to understand cell membrane and organelle morphologies

PubMed Central

Ramakrishnan, N.; Radhakrishnan, Ravi

2016-01-01

An intriguing question in cell biology is “how do cells regulate their shape?” It is commonly believed that the observed cellular morphologies are a result of the complex interaction among the lipid molecules (constituting the cell membrane), and with a number of other macromolecules, such as proteins. It is also believed that the common biophysical processes essential for the functioning of a cell also play an important role in cellular morphogenesis. At the cellular scale—where typical dimensions are in the order of micrometers—the effects arising from the molecular scale can either be modeled as equilibrium or non-equilibrium processes. In this chapter, we discuss the dynamically triangulated Monte Carlo technique to model and simulate membrane morphologies at the cellular scale, which in turn can be used to investigate several questions related to shape regulation in cells. In particular, we focus on two specific problems within the framework of isotropic and anisotropic elasticity theories: namely, (i) the origin of complex, physiologically relevant, membrane shapes due to the interaction of the membrane with curvature remodeling proteins, and (ii) the genesis of steady state cellular shapes due to the action of non-equilibrium forces that are generated by the fission and fusion of transport vesicles and by the binding and unbinding of proteins from the parent membrane.

Emotional collectives: How groups shape emotions and emotions shape groups.

Group settings are epicentres of emotional activity. Yet, the role of emotions in groups is poorly understood. How do group-level phenomena shape group members' emotional experience and expression? How are emotional expressions recognised, interpreted and shared in group settings? And how do such expressions influence the emotions, cognitions and behaviours of fellow group members and outside observers? To answer these and other questions, we draw on relevant theoretical perspectives (e.g., intergroup emotions theory, social appraisal theory and emotions as social information theory) and recent empirical findings regarding the role of emotions in groups. We organise our review according to two overarching themes: how groups shape emotions and how emotions shape groups. We show how novel empirical approaches break important new ground in uncovering the role of emotions in groups. Research on emotional collectives is thriving and constitutes a key to understanding the social nature of emotions.

The Shape of a Ponytail and the Statistical Physics of Hair Fiber Bundles

Goldstein, Raymond E.; Warren, Patrick B.; Ball, Robin C.

2012-02-01

From Leonardo to the Brothers Grimm our fascination with hair has endured in art and science. Yet, a quantitative understanding of the shapes of a hair bundles has been lacking. Here we combine experiment and theory to propose an answer to the most basic question: What is the shape of a ponytail? A model for the shape of hair bundles is developed from the perspective of statistical physics, treating individual fibers as elastic filaments with random intrinsic curvatures. The combined effects of bending elasticity, gravity, and bundle compressibility are recast as a differential equation for the envelope of a bundle, in which the compressibility enters through an ``equation of state.'' From this, we identify the balance of forces in various regions of the ponytail, extract the equation of state from analysis of ponytail shapes, and relate the observed pressure to the measured random curvatures of individual hairs.

Pattern and Process in the Comparative Study of Convergent Evolution.

PubMed

Mahler, D Luke; Weber, Marjorie G; Wagner, Catherine E; Ingram, Travis

2017-08-01

Understanding processes that have shaped broad-scale biodiversity patterns is a fundamental goal in evolutionary biology. The development of phylogenetic comparative methods has yielded a tool kit for analyzing contemporary patterns by explicitly modeling processes of change in the past, providing neontologists tools for asking questions previously accessible only for select taxa via the fossil record or laboratory experimentation. The comparative approach, however, differs operationally from alternative approaches to studying convergence in that, for studies of only extant species, convergence must be inferred using evolutionary process models rather than being directly measured. As a result, investigation of evolutionary pattern and process cannot be decoupled in comparative studies of convergence, even though such a decoupling could in theory guard against adaptationist bias. Assumptions about evolutionary process underlying comparative tools can shape the inference of convergent pattern in sometimes profound ways and can color interpretation of such patterns. We discuss these issues and other limitations common to most phylogenetic comparative approaches and suggest ways that they can be avoided in practice. We conclude by promoting a multipronged approach to studying convergence that integrates comparative methods with complementary tests of evolutionary mechanisms and includes ecological and biogeographical perspectives. Carefully employed, the comparative method remains a powerful tool for enriching our understanding of convergence in macroevolution, especially for investigation of why convergence occurs in some settings but not others.

2014-01-01

There are a number of anecdotal reports on demographic characteristics and academic success of accelerated-nursing students; yet few empirical studies have examined accelerated-nursing students NCLEX-RN success. Applying Knowles' adult learning theory as a guiding framework, the purpose of this qualitative study was to explore, from the accelerated-nursing students' perspective, the factors reported as contributing to their success on the NCLEX-RN. The research questions aimed to elicit participants' descriptions of their experiences and factors contributing to their success via individual interviews. The most significant finding the participants identified as the factor that contributed to their success was the practicing of NCLEX-RN questions. The findings of this study have several implications for educational policy and practice for universities and schools of nursing as the information gained from this study applies to recruitment and retention as well as curriculum and educational strategies in an accelerated-nursing program.

Practical implications of empirically studying moral decision-making.

This paper considers the practical question of why people do not behave in the way they ought to behave. This question is a practical one, reaching both into the normative and descriptive domains of morality. That is, it concerns moral norms as well as empirical facts. We argue that two main problems usually keep us form acting and judging in a morally decent way: firstly, we make mistakes in moral reasoning. Secondly, even when we know how to act and judge, we still fail to meet the requirements due to personal weaknesses. This discussion naturally leads us to another question: can we narrow the gap between what people are morally required to do and what they actually do? We discuss findings from neuroscience, economics, and psychology, considering how we might bring our moral behavior better in line with moral theory. Potentially fruitful means include nudging, training, pharmacological enhancement, and brain stimulation. We conclude by raising the question of whether such methods could and should be implemented.

Assessing physician needs to develop continuing medical education (CME) activities is an integral part of CME curriculum development. The purpose of the present study was to demonstrate the feasibility of identifying areas of perceived greatest needs for continuing medical education (CME) by using questions collected electronically at the point of care. This study is a secondary analysis of the "Just-in-Time" (JIT) information librarian consultation service database of questions using quantitative content analysis methods. The original JIT project demonstrated the feasibility of a real-time librarian service for answering questions asked by primary care clinicians at the point of care using a Web-based platform or handheld device. Data were collected from 88 primary care practitioners in Ontario, Canada, from October 2005 to April 2006. Questions were answered in less than 15 minutes, enabling clinicians to use the answer during patient encounters. Description of type and frequency of questions asked, including the organ system on which the questions focused, was produced using 2 classification systems, the "taxonomy of generic clinical questions" (TGCQ), and the International Classification for Primary Care version 2 (ICPC-2). Of the original 1889 questions, 1871 (99.0%) were suitable for analysis. A total of 970 (52%) of questions related to therapy; of these, 671 (69.2%) addressed questions about drug therapy, representing 36% of all questions. Questions related to diagnosis (24.8%) and epidemiology (13.5%) were also common. Organ systems questions concerning musculoskeletal, endocrine, skin, cardiac, and digestive systems were asked more than other categories. Questions collected at the point of care provide a valuable and unique source of information on the true learning needs of practicing clinicians. The TGCQ classification allowed us to show that a majority of questions had to do with treatment, particularly drug treatment, whereas the use of the ICPC-2 classification illustrated the great variety of questions asked about the diverse conditions encountered in primary care. It is feasible to use electronically collected questions asked by primary care clinicians in clinical practice to categorize self-identified knowledge and practice needs. This could be used to inform the development of future learning activities.

Improving consistency in large laboratory courses: a design for a standardized practical exam.

PubMed

Chen, Xinnian; Graesser, Donnasue; Sah, Megha

2015-06-01

Laboratory courses serve as important gateways to science, technology, engineering, and mathematics education. One of the challenges in assessing laboratory learning is to conduct meaningful and standardized practical exams, especially for large multisection laboratory courses. Laboratory practical exams in life sciences courses are frequently administered by asking students to move from station to station to answer questions, apply knowledge gained during laboratory experiments, interpret data, and identify various tissues and organs using various microscopic and gross specimens. This approach puts a stringent time limit on all questions regardless of the level of difficulty and also invariably increases the potential risk of cheating. To avoid potential cheating in laboratory courses with multiple sections, the setup for practical exams is often changed in some way between sections. In laboratory courses with multiple instructors or teaching assistants, practical exams may be handled inconsistently among different laboratory sections, due to differences in background knowledge, perceptions of the laboratory goals, or prior teaching experience. In this article, we describe a design for a laboratory practical exam that aims to align the assessment questions with well-defined laboratory learning objectives and improve the consistency among all laboratory sections.

Exploring arising moments and mindfulness in occupational therapists working in diverse clinical practice areas.

Reid, Denise; Naseer, Zahid

2012-10-01

An online survey was conducted with 72 Canadian occupational therapists to (1) explore if and how occupational therapists were aware of "arising moments" in clinical practice, which are moments that give rise to emotions, sensations, and thoughts, and (2) to examine therapists' responses to questions related to mindfulness. Participants described arising moments through an open-ended survey question. Framework analysis was used to develop key themes and subthemes. A modified Philadelphia Mindfulness Awareness (PHLMS) subscale with two additional survey questions "understanding of living in the moment and being present, and awareness of mindfulness" (sum = PAM) were used as indicators of mindfulness. There were significant differences in the means of PHLMS mindfulness among therapists working in diverse practice areas (F = 3.63, p = .009). Posthoc analysis revealed that therapists working in mental health had higher mean PHLMS-mindfulness scores than in all other groups. There were no significant differences in PAM mindfulness among the practice areas (ANOVA, F = 2.15, p = .08). However, posthoc tests showed that the participants in the mental health practice area had a significant difference with one group, general physical health. Findings have implications for practice in occupational therapy and education about mindfulness in occupational therapy.

The study examined how religious beliefs and practices impact upon medication and illness representations in chronic schizophrenia. One hundred three stabilized patients were included in Geneva's outpatient public psychiatric facility in Switzerland. Interviews were conducted to investigate spiritual and religious beliefs and religious practices and religious coping. Medication adherence was assessed through questions to patients and to their psychiatrists and by a systematic blood drug monitoring. Thirty-two percent of patients were partially or totally nonadherent to oral medication. Fifty-eight percent of patients were Christians, 2% Jewish, 3% Muslim, 4% Buddhist, 14% belonged to various minority or syncretic religious movements, and 19% had no religious affiliation. Two thirds of the total sample considered spirituality as very important or even essential in everyday life. Fifty-seven percent of patients had a representation of their illness directly influenced by their spiritual beliefs (positively in 31% and negatively in 26%). Religious representations of illness were prominent in nonadherent patients. Thirty-one percent of nonadherent patients and 27% of partially adherent patients underlined an incompatibility or contradiction between their religion and taking medication, versus 8% of adherent patients. Religion and spirituality contribute to shaping representations of disease and attitudes toward medical treatment in patients with schizophrenia. This dimension should be on the agenda of psychiatrists working with patients with schizophrenia. PMID:17213479

The prevalence of chronic illness is growing worldwide and management is increasingly undertaken by interprofessional teams, yet education is still generally provided in separate professions. The aim of this study was to explore the perspectives of New Zealand healthcare practitioners from seven professional groups involved in chronic care (general practice medicine, nursing, occupational therapy, pharmacy, physiotherapy, social work, and speech language therapy) on the core competencies required of those working in this area. The study was set in the context of the chronic care and shared decision-making (SDM) models. The core competencies for chronic care practitioners proposed by the World Health Organisation were used to shape the research questions. Focus groups with expert clinicians (n = 20) and semi-structured interviews with practitioners (n = 32) were undertaken. Findings indicated a high level of agreement that the core competencies were appropriate and relevant for chronic care practitioners but that many educational and practice gaps existed and interprofessional education in New Zealand was not currently addressing these gaps. Among the key issues highlighted for attention by educators and policy-makers were the following: teams and teamwork, professional roles and responsibilities, interprofessional communication, cultural competence, better engagement with patients, families, and carers, and common systems, information sharing and confidentiality.

Constructive neutral evolution: exploring evolutionary theory's curious disconnect.

PubMed

Stoltzfus, Arlin

2012-10-13

Constructive neutral evolution (CNE) suggests that neutral evolution may follow a stepwise path to extravagance. Whether or not CNE is common, the mere possibility raises provocative questions about causation: in classical neo-Darwinian thinking, selection is the sole source of creativity and direction, the only force that can cause trends or build complex features. However, much of contemporary evolutionary genetics departs from the conception of evolution underlying neo-Darwinism, resulting in a widening gap between what formal models allow, and what the prevailing view of the causes of evolution suggests. In particular, a mutationist conception of evolution as a 2-step origin-fixation process has been a source of theoretical innovation for 40 years, appearing not only in the Neutral Theory, but also in recent breakthroughs in modeling adaptation (the "mutational landscape" model), and in practical software for sequence analysis. In this conception, mutation is not a source of raw materials, but an agent that introduces novelty, while selection is not an agent that shapes features, but a stochastic sieve. This view, which now lays claim to important theoretical, experimental, and practical results, demands our attention. CNE provides a way to explore its most significant implications about the role of variation in evolution. Alex Kondrashov, Eugene Koonin and Johann Peter Gogarten reviewed this article.

Producing knowledge about racial differences: tracing scientists' use of "race" and "ethnicity" from grants to articles.

2013-01-01

The research and publication practices by which scientists produce biomedical knowledge about race and ethnicity remain largely unexamined, and most of the existing research looks at the knowledge production process at a single point in time. In light of this, we specifically focus on the questions of whether and in what ways researchers' discussions of race and ethnicity change over the course of the research process by comparing grant proposals to published articles. Using content analysis, we investigated the use of race and ethnicity in 72 grants funded by the National Cancer Institute of the National Institutes of Health between 1990 and 1999 and 144 matched articles published between 1996 and 2010, tracing the production of biomedical knowledge from study design to published findings. This is also the first study to look at whether the NIH Inclusion Mandate, which went into effect in June of 1994, changed the way investigators research and write about racial and ethnic differences. In following this knowledge production process, we explore how scientists "deliver" on their research proposal goals. In addition, we provide insight into whether and how state policies directed at guiding research practices can shape output. © 2013 American Society of Law, Medicine & Ethics, Inc.

Deafness, genetics and dysgenics.

PubMed

Nunes, Rui

2006-01-01

It has been argued by some authors that our reaction to deaf parents who choose deafness for their children ought to be compassion, not condemnation. Although I agree with the reasoning proposed I suggest that this practice could be regarded as unethical. In this article, I shall use the term "dysgenic" as a culturally imposed genetic selection not to achieve any improvement of the human person but to select genetic traits that are commonly accepted as a disabling condition by the majority of the social matrix; in short as a handicap. As in eugenics, dysgenics can be achieved in a positive and a negative way. Positive dysgenics intends to increase the overall number of people with a particular genetic trait. Marriage between deaf people or conceiving deaf children through reproductive technology are examples of positive dysgenics. Negative dysgenics can be obtained through careful prenatal or pre-implantation selection and abortion (or discarding) of normal embryos and foetuses. Only deaf children would be allowed to live. If dysgenics is seen as a programmed genetic intervention that undesirably shapes the human condition--like deliberately creating deaf or dwarf people--the professionals involved in reproductive technologies should answer the question if this should be an accepted ethical practice because the basic human right to an open future is violated.

Selim v Lele and the civil (industrial) conscription prohibition: constitutional protection against federal legislation controlling or privatising Australian public hospitals.

PubMed

Faunce, Thomas

2008-08-01

Selim v Lele (2008) 167 FCR 61; [2008] FCAFC 13 was a decision of the Federal Court which interpreted s 51(xxiiiA) of the Australian Constitution. This section accords the federal government, among other things, power to make laws with respect to the provision of "medical and dental services (but not so as to authorise any form of civil conscription)". The Federal Court decided that the phrase "civil conscription" was analogous to "industrial conscription". In that sense the Federal Court held that the prohibition was designed to preserve the employment autonomy of Australian medical practitioners or dentists, preventing federal laws that required them, either expressly or by practical compulsion, to work for the federal government or any industrial employer nominated or permitted by the federal government. The specific question in Selim v Lele was whether the imposition of standards and prohibition of "inappropriate practice" under the Health Insurance Act 1973 (Cth), ss 10, 20, 20A and Pt VAA, amounted to civil conscription. The court held they did not. The Federal Court also discussed in that context the sufficiency of "practical compulsion" in relation to the s 51(xxxiiiA) prohibition, The constitutional prohibition on "any form" of civil conscription provides one of the few rights protections in the Australian Constitution and may have an important role to play in shaping the limits of health care system privatisation in Australia.

HIV in (and out of) the clinic: biomedicine, traditional medicine and spiritual healing in Harare.

Contemporary lived experiences of the human immunodeficiency virus (HIV) are shaped by clinical and cultural encounters with illness. In sub-Saharan countries such as Zimbabwe, HIV is treated in very different ways in various therapeutic contexts including by biomedical experts, traditional medicine and faith healers. The co-existence of such expertise raises important questions around the potencies and limits of medicalisation and alternative healing practices in promoting HIV recovery. First, in this study, drawing on in-depth qualitative interviews with 60 people from poor urban areas in Harare, we explore the experiences of people living with and affected by HIV. Specifically, we sought to document, interrogate and reflect on their perceptions and experiences of biomedicine in relation to traditional medicine and spiritual healing. Their accounts indicate that traditional medicine and spiritual beliefs continue to significantly influence the way in which HIV is understood, and the forms of help and care people seek. Second, we observe the dramatic and overwhelmingly beneficial impact of Antiretroviral Therapy and conclude through Zimbabwean's own stories that limitations around delivery and wider structural inequalities impede its potential. Lastly, we explore some practical implications of the biomedical clinic (and alternative healing practices) being understood as sites of ideological and expert contestation. This paper aimed to add to our knowledge of the relationships between traditional medicine and spiritual healing in connection with biomedicine and how this may influence HIV treatment and prevention.

Solving the Supreme Problem: 100 years of selection and recruitment at the Journal of Applied Psychology.

Ployhart, Robert E; Schmitt, Neal; Tippins, Nancy T

2017-03-01

This article reviews 100 years of research on recruitment and selection published in the Journal of Applied Psychology. Recruitment and selection research has been present in the Journal from the very first issue, where Hall (1917) suggested that the challenge of recruitment and selection was the Supreme Problem facing the field of applied psychology. As this article shows, the various topics related to recruitment and selection have ebbed and flowed over the years in response to business, legal, and societal changes, but this Supreme Problem has captivated the attention of scientist-practitioners for a century. Our review starts by identifying the practical challenges and macro forces that shaped the sciences of recruitment and selection and helped to define the research questions the field has addressed. We then describe the evolution of recruitment and selection research and the ways the resulting scientific advancements have contributed to staffing practices. We conclude with speculations on how recruitment and selection research may proceed in the future. Supplemental material posted online provides additional depth by including a summary of practice challenges and scientific advancements that affected the direction of selection and recruitment research and an outline of seminal articles published in the Journal and corresponding time line. The 100-year anniversary of the Journal of Applied Psychology is very much the celebration of recruitment and selection research, although predictions about the future suggest there is still much exciting work to be done.

The genesis of public health ethics.

PubMed

Bayer, Ronald; Fairchild, Amy L

2004-11-01

As bioethics emerged in the 1960s and 1970s and began to have enormous impacts on the practice of medicine and research--fuelled, by broad socio-political changes that gave rise to the struggles of women, African Americans, gay men and lesbians, and the antiauthoritarianism impulse that characterised the New Left in democratic capitalist societies--little attention was given to the question of the ethics of public health. This was all the more striking since the core values and practices of public health, often entailing the subordination of the individual for the common good, seemed opposed to the ideological impulses of bioethics. Of what relevance is autonomy-focused bioethics for public health, with its mix of justifications including those that are either implicitly or explicitly paternalistic or that seek to impose strictures on individuals and communities in the name of collective welfare? To examine the deep divide between the central commitments of bioethics and the values that animate the practice of public health, we focus on a series of controversies implicating the concepts of privacy, liberty, and paternalism. Recognising the role of moral values in decision-making was a signal contribution of bioethics in its formative period. Over the past three decades a broad array of perspectives emerged under the rubric of bioethics but individualism remains central. As we commence the process of shaping an ethics of public health, it is clear that bioethics is the wrong place to start when thinking about the balances required in defence of the public's health.

For the past few decades, Spanish universities have been introduced gradually, the use of so-called New Technologies in the classroom. This is because its use contributes to improve outcomes in education at all levels. In this sense, it helps not only to expand knowledge as in traditional education, but teaches students to learn and encouraged them to be more independent, to develop and apply their knowledge in practice, their future employment use. The aim of this paper is to analyse the educational content and the degree of satisfaction students get through the use of a spreadsheet program to perform various practices of Agricultural Engineers courses of the Polytechnic University of Madrid. Weekly, the professor poses a practice with a detailed explanation of what is required and students have the opportunity to submit as many times as they want, over two weeks, the work developed. Students are encouraged to undertake individual work and to submit in the same day the exercise done because earlier is the presentation of results more opportunities to correct the mistakes. Regardless of students' knowledge on Excel, the professor explains each one of the Excel resources to be employed in the presented practice. Then, they have the opportunity to ask about them avoiding the scenario of not performing the practice due to ignore some Excel resources. The number of practices that are performed per year depend on the hours / credits that are assigned to each subject. On the other hand, to check the degree of student satisfaction with these practices, a anonymous questionnaire was performed consisting of 15 questions that can be grouped into four categories: consolidation of knowledge (4 questions), practice organization (7 questions), following indications (2 questions) and knowledge of Excel (2 questions). Results show high degree of students' satisfaction in their learning process and their applicability in the future.

Chemotherapy-resistant urothelial carcinoma has no uniformly curative therapy. Understanding how selective pressure from chemotherapy directs the evolution of urothelial carcinoma and shapes its clonal architecture is a central biological question with clinical implications. To address this question, we performed whole-exome sequencing and clonality analysis of 72 urothelial carcinoma samples, including 16 matched sets of primary and advanced tumors prospectively collected before and after chemotherapy. Our analysis provided several insights: (i) chemotherapy-treated urothelial carcinoma is characterized by intra-patient mutational heterogeneity, and the majority of mutations are not shared; (ii) both branching evolution and metastatic spread are very early events in the natural history of urothelial carcinoma; (iii) chemotherapy-treated urothelial carcinoma is enriched with clonal mutations involving L1 cell adhesion molecule (L1CAM) and integrin signaling pathways; and (iv) APOBEC-induced mutagenesis is clonally enriched in chemotherapy-treated urothelial carcinoma and continues to shape the evolution of urothelial carcinoma throughout its lifetime.

The science of self-assembly has undergone a radical shift from asking questions about why individual components self-organize into ordered structures, to manipulating the resultant order. However, the quest for far-reaching nanomanufacturing requires addressing an even more challenging question: how to form nanoparticle (NP) structures with designed architectures without explicitly prescribing particle positions. Here we report an assembly concept in which building instructions are embedded into NPs via DNA frames. The integration of NPs and DNA origami frames enables the fabrication of NPs with designed anisotropic and selective interactions. Using a pre-defined set of different DNA-framed NPs, we show it is possible to design diverse planar architectures, which include periodic structures and shaped meso-objects that spontaneously emerge on mixing of the different topological types of NP. Even objects of non-trivial shapes, such as a nanoscale model of Leonardo da Vinci's Vitruvian Man, can be self-assembled successfully.

The sweetest thing: the influence of angularity, symmetry, and the number of elements on shape-valence and shape-taste matches

A within-participants experiment was conducted in two countries (the UK and Colombia) in order to investigate the matching of shapes to taste words. Comparing the two countries allowed us to explore some of the cultural differences that have been reported thus far solely in terms of people's visual preferences. In particular, we addressed the question of whether properties other than angularity influence shape-valence and shape-taste matching (crossmodal correspondences). The participants in the present study repeatedly matched eight shapes, varying in terms of their angularity, symmetry, and number of elements to one of two words—pleasant or unpleasant and sweet or sour. Participants' choices, as well as the latency of their responses, and their hand movements, were evaluated. The participants were more likely to judge those shapes that were rounder, symmetrical, and those shapes that had fewer elements as both pleasant and sweet. Those shapes that were more angular, asymmetrical, and that had a greater number of elements, were more likely to be judged as both unpleasant and sour instead. The evidence presented here therefore suggests that aside from angularity and roundness, both symmetry/asymmetry and the number of elements present in a shape also influence valence and taste categorizations.

Translational research in behavior analysis: historical traditions and imperative for the future.

Mace, F Charles; Critchfield, Thomas S

"Pure basic" science can become detached from the natural world that it is supposed to explain. "Pure applied" work can become detached from fundamental processes that shape the world it is supposed to improve. Neither demands the intellectual support of a broad scholarly community or the material support of society. Translational research can do better by seeking innovation in theory or practice through the synthesis of basic and applied questions, literatures, and methods. Although translational thinking has always occurred in behavior analysis, progress often has been constrained by a functional separation of basic and applied communities. A review of translational traditions in behavior analysis suggests that innovation is most likely when individuals with basic and applied expertise collaborate. Such innovation may have to accelerate for behavior analysis to be taken seriously as a general-purpose science of behavior. We discuss the need for better coordination between the basic and applied sectors, and argue that such coordination compromises neither while benefiting both.

How much is enough? The recurrent problem of setting measurable objectives in conservation

International agreements, environmental laws, resource management agencies, and environmental nongovernmental organizations all establish objectives that define what they hope to accomplish. Unfortunately, quantitative objectives in conservation are typically set without consistency and scientific rigor. As a result, conservationists are failing to provide credible answers to the question "How much is enough?" This is a serious problem because objectives profoundly shape where and how limited conservation resources are spent, and help to create a shared vision for the future. In this article we develop guidelines to help steer conservation biologists and practitioners through the process of objective setting. We provide three case studies to highlight the practical challenges of objective setting in different social, political, and legal contexts. We also identify crucial gaps in our science, including limited knowledge of species distributions and of large-scale, long-term ecosystem dynamics, that must be filled if we hope to do better than setting conservation objectives through intuition and best guesses. ?? 2005 American Institute of Biological Sciences.

Fostering Recovery from Life-Transforming Mental Health Disorders: A Synthesis and Model

PubMed Central

Green, Carla A.

2012-01-01

In the past, “recovery” from serious mental health problems has been variously defined and generally considered rare. Current evidence suggests that some form of recovery is both possible and common, yet we know little about the processes that differentiate those who recover from those who do not. This paper discusses approaches to defining recovery, proposes a model for fostering, understanding, and studying recovery, and suggests questions for clinicians, researchers, and policy makers. The proposed model is a synthesis of work from the field of mental health as well as from other disciplines. Environment, resources, and strains, provide the backdrop for recovery; core recovery processes include development, learning, healing, and their primary behavioral manifestation, adaptation. Components facilitating recovery include sources of motivation (hope, optimism, and meaning), prerequisites for action (agency, control, and autonomy), and capacity (competence and dysfunction). Attending to these aspects of the recovery process could help shape clinical practice, and systems that provide and finance mental health care, in ways that promote recovery. PMID:23264751

Ecologists who specialize in translational ecology (TE) seek to link ecological knowledge to decision making by integrating ecological science with the full complement of social dimensions that underlie today's complex environmental issues. TE is motivated by a search for outcomes that directly serve the needs of natural resource managers and decision makers. This objective distinguishes it from both basic and applied ecological research and, as a practice, it deliberately extends research beyond theory or opportunistic applications. TE is uniquely positioned to address complex issues through interdisciplinary team approaches and integrated scientist–practitioner partnerships. The creativity and context‐specific knowledge of resource managers, practitioners, and decision makers inform and enrich the scientific process and help shape use‐driven, actionable science. Moreover, addressing research questions that arise from on‐the‐ground management issues – as opposed to the top‐down or expert‐oriented perspectives of traditional science – can foster the high levels of trust and commitment that are critical for long‐term, sustained engagement between partners.

Beyond the Border and Into the Heartland: Spatial Patterning of U.S. Immigration Detention.

Moinester, Margot

2018-06-01

The expansion of U.S. immigration enforcement from the borders into the interior of the country and the fivefold increase in immigration detentions and deportations since 1995 raise important questions about how the enforcement of immigration law is spatially patterned across American communities. Focusing on the practice of immigration detention, the present study analyzes the records of all 717,160 noncitizens detained by Immigration and Customs Enforcement (ICE) in 2008 and 2009-a period when interior enforcement was at its peak-to estimate states' detention rates and examine geographic variation in detention outcomes, net of individual characteristics. Findings reveal substantial state heterogeneity in immigration detention rates, which range from approximately 350 detentions per 100,000 noncitizens in Connecticut to more than 6,700 detentions per 100,000 noncitizens in Wyoming. After detainment, individuals' detention outcomes are geographically stratified, especially for detainees eligible for pretrial release. These disparities indicate the important role that geography plays in shaping individuals' chances of experiencing immigration detention and deportation.

The politics of verification and the control of nuclear tests, 1945-1980

1990-01-01

This dissertation addresses two questions: (1) why has agreement been reached on verification regimes to support some arms control accords but not others; and (2) what determines the extent to which verification arrangements promote stable cooperation. This study develops an alternative framework for analysis by examining the politics of verification at two levels. The logical politics of verification are shaped by the structure of the problem of evaluating cooperation under semi-anarchical conditions. The practical politics of verification are driven by players' attempts to use verification arguments to promote their desired security outcome. The historical material shows that agreements on verificationmore » regimes are reached when key domestic and international players desire an arms control accord and believe that workable verification will not have intolerable costs. Clearer understanding of how verification is itself a political problem, and how players manipulate it to promote other goals is necessary if the politics of verification are to support rather than undermine the development of stable cooperation.« less

This round table discussion takes the diversity of discourse and practice shaping modern knowledge about childhood as an opportunity to engage with recent historiographical approaches in the history of science. It draws attention to symmetries and references among scientific, material, literary and artistic cultures and their respective forms of knowledge. The five participating scholars come from various fields in the humanities and social sciences and allude to historiographical and methodological questions through a range of examples. Topics include the emergence of children's rooms in US consumer magazines, research on the unborn in nineteenth-century sciences of development, the framing of autism in nascent child psychiatry, German literary discourses about the child's initiation into writing, and the sociopolitics of racial identity in the photographic depiction of African American infant corpses in the early twentieth century. Throughout the course of the paper, childhood emerges as a topic particularly amenable to interdisciplinary perspectives that take the history of science as part of a broader history of knowledge.

Our aim is to contribute to the rational use of antibiotics prescribed by family doctors when a patient consults for a dental problem. Nowadays we should not ask which antibiotic to give. The question has to be if we need to prescribe antibiotics in front of the most common odontogenic infections seen in our practice. We review the main dental infections, which should be their appropriate management and the role of prevention. We need to know the complexity of the oral microbiome because it?ll depend on the appropriateness of the antibiotherapy, the evolution towards cure or progression of some odontogenic infections. The bacterial plaque, formed by the biofilm, behaves as a barrier to the action of antimicrobials. It?s in the prevention of its development as well as in it mechanical elimination once shaped, in what the family doctor should insist. We must transmit antibiotics don?t heal dental pain.

Another missed opportunity? Recognition of alcohol use problems by mental health providers.

PubMed

Freimuth, Marilyn

2008-09-01

Alcohol use problems (AUPs) are prevalent among people seeking psychotherapy. Despite mandates from managed care companies to routinely screen for AUPs, little is known about the screening practices of providers or their ability to identify AUPs based on presenting symptoms. Participants (N = 117) read two case vignettes and suggested initial diagnoses and questions they would ask in order to clarify a diagnosis. Participants were more likely to ask about substance use and diagnose an AUP when the vignette contained explicit reference to the client's substance use as compared to a vignette where the signs of an AUP were more subtle. In both vignettes, a mental health problem was a more likely diagnosis than an AUP. Neither participant attributes nor personal or professional experiences with AUPs reliably shaped responses to the vignettes. The findings are discussed in light of their implications for future research and improved training in addictions for mental health providers.

Capillary forces exerted by liquid drops caught between crossed cylinders. A 3-D meniscus problem with free contact line

NASA Technical Reports Server (NTRS)

Patzek, T. W.; Scriven, L. E.

1982-01-01

The Young-Laplace equation is solved for three-dimensional menisci between crossed cylinders, with either the contact line fixed or the contact angle prescribed, by means of the Galerkin/finite element method. Shapes are computed, and with them the practically important quantities: drop volume, wetted area, capillary pressure force, surface tension force, and the total force exerted by the drop on each cylinder. The results show that total capillary force between cylinders increases with decreasing contact angle, i.e. with better wetting. Capillary force is also increases with decreasing drop volume, approaching an asymptotic limit. However, the wetted area on each cylinder decreases with decreasing drop volume, which raises the question of the optimum drop volume to strive for, when permanent bonding is sought from solidified liquid. For then the strength of the bond is likely to depend upon the area of contact, which is the wetted area when the bonding agent was introduced in liquid form.

Benefits of “Observer Effects”: Lessons from the Field

PubMed Central

Monahan, Torin; Fisher, Jill A.

2011-01-01

This paper responds to the criticism that “observer effects” in ethnographic research necessarily bias and therefore invalidate research findings. Instead of aspiring to distance and detachment, some of the greatest strengths of ethnographic research lie in cultivating close ties with others and collaboratively shaping discourses and practices in the field. Informants’ performances – however staged for or influenced by the observer – often reveal profound truths about social and/or cultural phenomena. To make this case, first we mobilize methodological insights from the field of science studies to illustrate the contingency and partiality of all knowledge and to challenge the notion that ethnography is less objective than other research methods. Second, we draw upon our ethnographic projects to illustrate the rich data that can be obtained from “staged performances” by informants. Finally, by detailing a few examples of questionable behavior on the part of informants, we challenge the fallacy that the presence of ethnographers will cause informants to self-censor.

The PISA problems for mathematics could be classified into four areas, namely quantity, space and shape, change and relationship, and uncertainty. The research results that would be presented in this paper were the result test for quantity, and change and relationship problems. In the adapting PISA test, there were fifteen questions that consist of two questions for the quantity group, six questions for space and shape group, three questions for the change and relationship group, and four questions for uncertainty. Subjects in this study were 18 students from 11 junior high schools in Yogyakarta, Central Java, and Banten. The type of research that used by the researchers was a qualitative research. For the first quantity problem, there were 38.89 % students who achieved level 3. For the second quantity problem, there were 88.89 % students who achieved level 2. For part a of the first change and relationship problem, there were 55.56 % students who achieved level 5. For part b of the first change and relationship problem, there were 77.78 % students who achieved level 2. For the second change and relationship problem, there were 38.89 % students who achieved level 2.

Female genital cutting (FGC) has major implications for women's physical, sexual and psychological health, and eliminating the practice is a key target for public health policy-makers. To date one of the main barriers to achieving this has been an inability to infer privately-held views on FGC within communities where it is prevalent. As a sensitive (and often illegal) topic, people are anticipated to hide their true support for the practice when questioned directly. Here we use an indirect questioning method (unmatched count technique) to identify hidden support for FGC in a rural South Central Ethiopian community where the practice is common, but thought to be in decline. Employing a socio-demographic household survey of 1620 Arsi Oromo adults, which incorporated both direct and indirect direct response (unmatched count) techniques we compare directly-stated versus privately-held views in support of FGC, and individual variation in responses by age, gender and education and target female (daughters versus daughters-in-law). Both genders express low support for FGC when questioned directly, while indirect methods reveal substantially higher acceptance (of cutting both daughters and daughters-in-law). Educated adults (those who have attended school) are privately more supportive of the practice than they are prepared to admit openly to an interviewer, indicating that education may heighten secrecy rather than decrease support for FGC. Older individuals hold the strongest views in favour of FGC (particularly educated older males), but they are also more inclined to conceal their support for FGC when questioned directly. As these elders represent the most influential members of society, their hidden support for FGC may constitute a pivotal barrier to eliminating the practice in this community. Our results demonstrate the great potential for indirect questioning methods to advance knowledge and inform policy on culturally-sensitive topics like FGC; providing more reliable data and improving understanding of the "true" drivers of FGC.

Study on the method of maintaining bathtub water temperature

Wang, Xiaoyan

2017-05-01

In order to make the water temperature constant and the spillage to its minimum, we use finite element method and grid transformation and have established an optimized model for people in the bathtub both in time and space, which is based on theories of heat convection and heat conduction and three-dimensional second-order equation. For the first question, we have worked out partial differential equations for three-dimensional heat convection. In the meantime, we also create an optimized temperature model in time and space by using initial conditions and boundary conditions. For the second question we have simulated the shape and volume of the tub and the human gestures in the tub based on the first question. As for the shape and volume of the tub, we draw conclusion that the tub whose surface area is little contains water with higher temperature. Thus, when we are designing bathtubs we can decrease the area so that we'll have less loss heat. For different gestures when people are bathing, we have found that gestures have no obvious influence on variations of water temperature. Finally, we did some simulating calculations, and did some analysis on precision and sensitivity

Editors' Introduction: Abstract Concepts: Structure, Processing, and Modeling.

Bolognesi, Marianna; Steen, Gerard

2018-06-22

Our ability to deal with abstract concepts is one of the most intriguing faculties of human cognition. Still, we know little about how such concepts are formed, processed, and represented in mind. For example, because abstract concepts do not designate referents that can be experienced through our body, the role of perceptual experiences in shaping their content remains controversial. Current theories suggest a variety of alternative explanations to the question of "how abstract concepts are represented in the human mind." These views pinpoint specific streams of semantic information that would play a prominent role in shaping the content of abstract concepts, such as situation-based information (e.g., Barsalou & Wiemer-Hastings, ), affective information (Kousta, Vigliocco, Vinson, Andrews, & Del Campo, ), and linguistic information (Louwerse, ). Rarely, these theoretical views are directly compared. In this special issue, current views are presented in their most recent and advanced form, and directly compared and discussed in a debate, which is reported at the end of each article. As a result, new exciting questions and challenges arise. These questions and challenges, reported in this introductory article, can arguably pave the way to new empirical studies and theoretical developments on the nature of abstract concepts. © 2018 Cognitive Science Society, Inc.

Many practical clinical questions regarding the management of human immunodeficiency virus (HIV)–associated neurocognitive disorder (HAND) remain unanswered. We sought to identify and develop practical answers to key clinical questions in HAND management. Sixty-six specialists from 30 countries provided input into the program, which was overseen by a steering committee. Fourteen questions were rated as being of greatest clinical importance. Answers were drafted by an expert group based on a comprehensive literature review. Sixty-three experts convened to determine consensus and level of evidence for the answers. Consensus was reached on all answers. For instance, good practice suggests that all HIV patients should be screened for HAND early in disease using standardized tools. Follow-up frequency depends on whether HAND is already present or whether clinical data suggest risk for developing HAND. Worsening neurocognitive impairment may trigger consideration of antiretroviral modification when other causes have been excluded. The Mind Exchange program provides practical guidance in the diagnosis, monitoring, and treatment of HAND. PMID:23175555

The present study investigated the influence of peers' and family members' body shapes on the perception of body image and desire for thinness in Japanese female students. The study included 342 female, Japanese university students between the ages of 18 years and 22 years. They completed an anonymous questionnaire, which included questions related to anthropometry and body perception. Eating behavior was assessed by the Japanese version of the Eating Attitude Test-26. Many students overestimated their body shape (81.2% of underweight students and 74.6% of normal students) and had a desire for thinness (41.0% of underweight students, 88.2% of normal students, and 100% of overweight students). One of the main reasons for the overestimation of their body shape was comparison with others. Participants who were interested in a friend's body shape were almost three times more likely to have a desire for thinness than those who were not interested in a female friend's body shape (odds ratio: 3.06, P=0.014). The results indicate a possibility that a female Japanese student's young female friends' body shapes, influences her desire for thinness or her perception of her own body shape.

Background Research conducted in earlier phases of this study prospectively identified a number of concerns related to the safe administration of multiple intravenous (IV) infusions in Ontario hospitals. Objective To investigate the potential prevalence of practices or policies that may contribute to the patient safety risks identified in Phase 1b of this study. Data Sources and Review Methods Sixty-four survey responses were analyzed from clinical units where multiple IV infusions may occur (e.g., adult intensive care units). Survey questions were organized according to the topics identified in Phase 1b as potential contributors to patient harm (e.g., labelling practices, patient transfer practices, secondary infusion policies). Results Survey results indicated suboptimal practices and policies in some clinical units, and variability in a number of infusion practices. Key areas of concern included the following: use of primary IV tubing without back check valves when administering secondary infusions administration of secondary infusions with/as high-alert continuous IV medications potential confusion about how IV tubing should be labelled to reflect replacement date and time interruptions to IV therapy due to IV pump and/or tubing changes when patients are transferred between clinical units coadministration of continuous or intermittent infusions on central venous pressure monitoring ports variability in respondents’ awareness of the infusion pump's bolus capabilities Limitations Due to the limited sample size, survey responses may not be representative of infusion practices across Ontario. Answers to some questions indicated that the intent of the questions might have been misunderstood. Due to a design error, 1 question about bolus administration methods was not shown to as many respondents as appropriate. Conclusions The Ontario survey revealed variability in IV infusion practice across the province and potential opportunities to improve safety. PMID:26257837

"This is a question we have to ask everyone": asking young people about self-harm and suicide.

PubMed

O'Reilly, M; Kiyimba, N; Karim, K

2016-10-01

WHAT IS KNOWN ON THE SUBJECT?: An essential part of the mental health assessment is to evaluate the risk of harm to self. Fundamentally this involves asking directly about self-harming behaviour and suicidal thoughts or urges, but practitioners often find it difficult to open up these conversations. This evaluation of risk is particularly important as self-harm and suicidal thoughts are frequently found in young people who attend mental health services. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Young people are not always routinely asked directly about self-harm or suicidal thoughts when they are assessed. There are two ways that mental health practitioners introduce this topic: first, by building up to it by initially asking about general feelings, and second by stating that it is a requirement to ask everyone. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: These questions should not be avoided by mental health practitioners just because they are difficult. We offer suggestions as to how to ask questions about self-harm and suicide based on real-world practice. Introduction Questions about self-harm and suicide are essential in risk assessments with children and young people, yet little is known about how mental health practitioners do this. Aim The core aim was to examine how questions about self-harm and suicidal ideation are asked in real-world practice. Method A qualitative design was employed to analyse 28 video-recorded naturally occurring mental health assessments in a child and adolescent mental health service. Data were analysed using conversation analysis (CA). Results In 13 cases young people were asked about self-harm and suicide, but 15 were not. Analysis revealed how practitioners asked these questions. Two main styles were revealed. First was an incremental approach, beginning with inquiries about emotions and behaviours, building to asking about self-harm and suicidal intent. Second was to externalize the question as being required by outside agencies. Discussion The study concluded that the design of risk questions to young people had implications for how open they were to engaging with the practitioner. Implications for practice The study has implications for training and practice for psychiatric nurses and other mental health practitioners in feeling more confident in communicating with young people about self-harm and suicidal ideation. © 2016 John Wiley & Sons Ltd.

The importance that prospective patients place on practice characteristics when choosing an orthodontic practice has not been extensively reported. The objective of this research was to develop a valid and reliable questionnaire to address the relative importance of orthodontic office and doctor characteristics for prospective patients or parents of child patients during the initial orthodontic office consultation. An initial questionnaire, based on published literature, was field-tested on 16 subjects to assess its validity. Based on the field test, the questionnaire was modified and tested for reliability by using a test-retest method. The questionnaire covered the following areas: doctor, office, staff, and finances. The reliability study included 2 groups of subjects: 12 consecutive prospective adult patients and 41 consecutive parents of prospective child patients. The questionnaires consisted of 43 and 50 questions for the adult patients and the parents of patients, respectively. The subjects rated the importance of practice characteristics in their selection of an orthodontic practice using a 100-mm visual analog scale anchored at "not important at all" and "most important." Reliability was analyzed by using the intraclass correlation coefficient (ICC). Summary scores of all 53 subjects showed excellent reliability (ICC, 0.88; range, 0.61-1.0). Summary scores of all 50 questions showed acceptable reliability (ICC, 0.70; range, 0.45-0.88). Twenty-one questions had excellent reliability (ICC, >.75), and 29 questions had fair-to-good reliability (ICC, 0.41-0.75). No questions showed poor reliability (ICC, <0.4). The pilot study data indicated that the overall reliability of the questionnaire is acceptable. Copyright © 2011 American Association of Orthodontists. Published by Mosby, Inc. All rights reserved.

2016-02-01

Antenatal mental health assessment is increasingly common in high-income countries. Despite lacking evidence on validation or acceptability, the Whooley questions (modified PHQ-2) and Arroll 'help' question are used in the UK at booking (the first formal antenatal appointment) to identify possible cases of depression. This study investigated validation of the questions and women's views on assessment. Women (n = 191) booking at an inner-city hospital completed the Whooley and Arroll questions as part of their routine clinical care then completed a research questionnaire containing the Edinburgh postnatal depression scale (EPDS). A purposive subsample (n = 22) were subsequently interviewed. The Whooley questions 'missed' half the possible cases identified using the EPDS (EPDS threshold ≥ 10: sensitivity 45.7 %, specificity 92.1 %; ≥ 13: sensitivity 47.8 %, specificity 86.1 %), worsening to nine in ten when adopting the Arroll item (EPDS ≥ 10: sensitivity 9.1 %, specificity 98.2 %; ≥ 13: sensitivity 9.5 %, specificity 97.1 %). Women's accounts indicated that under-disclosure relates to the context of assessment and perceived relevance of depression to maternity services. Depression symptoms are under-identified in current local practice. While validated tools are needed that can be readily applied in routine maternity care, psychometric properties will be influenced by the context of disclosure when implemented in practice.

Explanation, motivation and question posing routines in university mathematics teachers' pedagogical discourse: a commognitive analysis

NASA Astrophysics Data System (ADS)

Viirman, Olov

2015-11-01

This paper investigates the teaching practices used by university mathematics teachers when lecturing, a topic within university mathematics education research which is gaining an increasing interest. In the study, a view of mathematics teaching as a discursive practice is taken, and Sfard's commognitive framework is used to investigate the teaching practices of seven Swedish university mathematics teachers on the topic of functions. The present paper looks at the discourse of mathematics teaching, presenting a categorization of the didactical routines into three categories - explanation, motivation and question posing routines. All of these are present in the discourses of all seven teachers, but within these general categories, a number of different sub-categories of routines are found, used in different ways and to different extent by the various teachers. The explanation routines include known mathematical facts, summary and repetition, different representations, everyday language, and concretization and metaphor; the motivation routines include reference to utility, the nature of mathematics, humour and result focus; and the question posing routines include control questions, asking for facts, enquiries and rhetorical questions. This categorization of question posing routines, for instance, complements those already found in the literature. In addition to providing a valuable insight into the teaching of functions at the university level, the categorizations presented in the study can also be useful for investigating the teaching of other mathematical topics.

Teachers' understandings and enactments of social and environmental justice issues in the classroom: What's "critical" in the manufacturing of road-smart squirrels?

NASA Astrophysics Data System (ADS)

Sammel, Alison J.

How do five new teachers understand and enact counter-hegemonic pedagogies in their own classes? This study developed from this question. The question arose as I taught critical environmental education, a counter-hegemonic pedagogy, to preservice science teachers. I encouraged the exploration of social and environmental injustices and how they function to reproduce dominant economic agendas. To understand how five teachers, in the second year of their practice and my former students, made sense of the critical environmental education I taught them, I used Gadamer's hermeneutic phenomenology as my research frame. Gadamer argues that meaning develops through dialogue, so data collection occurred mainly through lively research conversations over leisurely dinners. As practicing teachers, the six of us jointly explored taken-for-granted meanings and actions in our everyday pedagogical experiences. In these conversations we made meaning (the hermeneutic aspect) of the lived experiences (phenomenological aspect) of incorporating critical environmental education into our practices. This led me to a deeper understanding and increased awareness of how science education reform agendas have influenced and shaped our individual science pedagogies. The analytic lens of critical education showed that these teachers were strongly influenced by the dominant science reform agenda. Regardless of the science curriculum, or the strong social and environmental beliefs some of these teachers held, they did not perceive the teaching of the social and environmental justice issues to be 'critical' or 'their job.' They demonstrated a belief that it was 'critical' to teach well-defined, "hard science" facts. Student success, hence teacher success, involved playing the academic game well and gaining long-term financial security. Re/viewing the data stories through the additional analytic lens of feminist poststructuralism, I saw how dominant discourse constructs the identity of teachers, their desires, and enforces self-discipline. Dominant educational discourse constricted and regulated their understandings of what it means to be a 'good' teacher. They were not able to see that being a 'good' teacher could include enacting counter-hegemonic pedagogies.

Suspending the next turn as a form of repair initiation: evidence from Argentine Sign Language

PubMed Central

Manrique, Elizabeth; Enfield, N. J.

2015-01-01

Practices of other-initiated repair deal with problems of hearing or understanding what another person has said in the fast-moving turn-by-turn flow of conversation. As such, other-initiated repair plays a fundamental role in the maintenance of intersubjectivity in social interaction. This study finds and analyses a special type of other-initiated repair that is used in turn-by-turn conversation in a sign language: Argentine Sign Language (Lengua de Señas Argentina or LSA). We describe a type of response termed a “freeze-look,” which occurs when a person has just been asked a direct question: instead of answering the question in the next turn position, the person holds still while looking directly at the questioner. In these cases it is clear that the person is aware of having just been addressed and is not otherwise accounting for their delay in responding (e.g., by displaying a “thinking” face or hesitation, etc.). We find that this behavior functions as a way for an addressee to initiate repair by the person who asked the question. The “freeze-look” results in the questioner “re-doing” their action of asking a question, for example by repeating or rephrasing it. Thus, we argue that the “freeze-look” is a practice for other-initiation of repair. In addition, we argue that it is an “off-record” practice, thus contrasting with known on-record practices such as saying “Huh?” or equivalents. The findings aim to contribute to research on human understanding in everyday turn-by-turn conversation by looking at an understudied sign language, with possible implications for our understanding of visual bodily communication in spoken languages as well.

Epidemics have been important in human history. This article discusses epidemics as part of a metabolic dialectics of humanity within nature. The creative thoughts and actions of those people most threatened by HIV/AIDS, and the thoughts and actions of science, have shaped both each other and the virus. The virus has reacted through mutation in ways that mimic strategic intelligence. The dialectics of capital and states has shaped these interactions and, in some cases, been shaped by them. Practical action to minimize the harms epidemics do can be strengthened by understanding of these epidemics, and Marxist theory and practices can be strengthened by understanding the dialectics of public health and the struggles around it more fully.

Flame Shapes of Luminous NonBuoyant Laminar Coflowing Jet Diffusion Flames

NASA Technical Reports Server (NTRS)

Lin, K.-C.; Faeth, G. M.

1999-01-01

Laminar diffusion flames are of interest as model flame systems that are more tractable for analysis and experiments than practical turbulent diffusion flames. Certainly understanding laminar flames must precede understanding more complex turbulent flames while man'y laminar diffusion flame properties are directly relevant to turbulent diffusion flames using laminar flamelet concepts. Laminar diffusion flame shapes have been of interest since the classical study of Burke and Schumann because they involve a simple nonintrusive measurement that is convenient for evaluating flame structure predictions. Motivated by these observations, the shapes of laminar flames were considered during the present investigation. The present study was limited to nonbuoyant flames because most practical flames are not buoyant. Effects of buoyancy were minimized by observing flames having large flow velocities at small pressures. Present methods were based on the study of the shapes of nonbu,3yant round laminar jet diffusion flames of Lin et al. where it was found that a simple analysis due to Spalding yielded good predictions of the flame shapes reported by Urban et al. and Sunderland et al.

To develop recommendations for the physical and laboratory-test follow-up of patients with rheumatoid arthritis (RA) seen in everyday practice, using evidence from the literature, supplemented with expert opinion when needed. A scientific committee selected 7-10 questions using the Delphi consensus procedure. Evidence-based responses to each question were sought in the literature and were then used by a panel to develop recommendations. To fill in gaps in knowledge from the literature, the panelists relied on their personal opinion. The seven questions dealt with the physical and laboratory-test follow-up of RA and the factors predicting disease severity. The literature review identified 799 articles whose title and abstract suggested relevance to the study. Elimination of articles that provided no data on the study topic left 128 original articles. The panel developed seven recommendations, one for each question, which were accepted by consensus. Recommendations about the physical and laboratory-test follow-up of patients with RA seen in everyday practice were developed. Because they constitute an objective foundation built by consensus among experts, should improve the uniformity and quality of care provided to RA patients in everyday practice.

Wig fragments or fibers may occasionally be recognized as potential physical evidence during criminal investigations. While analytical methods traditionally adopted for the examination of textile fibers are utilized for the characterizations and comparisons of wig specimens, it is essential to understand in deeper detail the valuable contribution of features of these non-routine evidentiary materials as well as the relationship of the gathered analytical data. This study explores the dependence between the microscopic features of cross-sectional shapes and the polymer type gathered by Fourier transform infrared (FTIR) spectroscopy. The discriminating power of the two methods of cross-sectioning and FTIR spectroscopy was also investigated. Forty-one synthetic wigs varying in both quality and price were collected: twenty-three brown, twelve blondes and six black samples. The collected samples were observed using light microscopy methods (bright field illumination and polarized light), before obtaining cross-sections using the Joliff method and analyze them using FTIR spectroscopy. The forty-one samples were divided into ten groups based on one or more of the ten types of cross-sectional shapes that were observed. The majority of encountered cross-sectional shapes were defined as horseshoe, dog bone and lobular. Infrared spectroscopy confirmed modacrylic to be the most prevalent fiber type. Blends of modacrylic and polyvinyl chloride fibers were also observed as well as polypropylene wig samples. The Goodman and Kruskal lambda statistical test was used and showed that the cross-sectional shape and infrared profile were related. From an evidentiary value perspective, this finding has implications when addressing questions about a common source between questioned wig specimens and a wig reference sample.

Undergraduate healthcare ethics education, moral resilience, and the role of ethical theories.

PubMed

Monteverde, Settimio

2014-06-01

This article combines foundational and empirical aspects of healthcare education and develops a framework for teaching ethical theories inspired by pragmatist learning theory and recent work on the concept of moral resilience. It describes an exemplary implementation and presents data from student evaluation. After a pilot implementation in a regular ethics module, the feasibility and acceptance of the novel framework by students were evaluated. In addition to the regular online module evaluation, specific questions referring to the teaching of ethical theories were added using simple (yes/no) and Likert rating answer formats. At the Bern University of Applied Sciences, a total of 93 students from 2 parallel sub-cohorts of the bachelor's program in nursing science were sent the online survey link after having been exposed to the same modular contents. A total of 62% of all students participated in the survey. The survey was voluntary and anonymous. Students were free to write their name and additional comments. Students consider ethical theories-as taught within the proposed framework-as practically applicable, useful, and transferable into practice. Teaching ethical theories within the proposed framework overcomes the shortcomings described by current research. Students do not consider the mutually exclusive character of ethical theories as an insurmountable problem. The proposed framework is likely to promote the effectiveness of healthcare ethics education. Inspired by pragmatist learning theory, it enables students to consider ethical theories as educative playgrounds that help them to "frame" and "name" the ethical issues they encounter in daily practice, which is seen as an expression of moral resilience. Since it does not advocate a single ethical theory, but is open to the diversity of traditions that shape ethical thinking, it promotes a culturally sensitive, ethically reflected healthcare practice. © The Author(s) 2013.

The future is now: Technology's impact on the practice of genetic counseling.

2018-03-01

Smartphones, artificial intelligence, automation, digital communication, and other types of technology are playing an increasingly important role in our daily lives. It is no surprise that technology is also shaping the practice of medicine, and more specifically the practice of genetic counseling. While digital tools have been part of the practice of medical genetics for decades, such as internet- or CD-ROM-based tools like Online Mendelian Inheritance in Man and Pictures of Standard Syndromes and Undiagnosed Malformations in the 1980s, the potential for emerging tools to change how we practice and the way patients consume information is startling. Technology has the potential to aid in at-risk patient identification, assist in generating a differential diagnosis, improve efficiency in medical history collection and risk assessment, provide educational support for patients, and streamline follow-up. Here we review the historic and current uses of technology in genetic counseling, identify challenges to integration, and propose future applications of technology that can shape the practice of genetic counseling. © 2018 Wiley Periodicals, Inc.

The ethics curriculum for doctor of nursing practice programs.

PubMed

Peirce, Anne Griswold; Smith, Jennifer A

2008-01-01

Ethical questions dealt with by nurses who have Doctor of Nursing Practice (DNP) degrees include traditional bioethical questions, but also business and legal ethics. Doctorally prepared nurses are increasingly in positions to make ethical decisions rather than to respond to decisions made by others. The traditional master's-degree advanced practice nursing curriculum does not address the extended expertise and decision-making skills needed by DNP practitioners as they face these new types of ethical dilemmas. We propose that a curricular framework that addresses clinical, research, business, and legal ethics is needed by all DNP students.

A cross-sectional survey was conducted with the objective to explore a community's knowledge and practices towards prevention of Influenza A (H1N1) in three residential areas in Tampin. Respondents were randomly selected from a list of residences and interviewed face-to-face using a structured questionnaire. A total of 221 respondents (80.9%) were involved with the majority (64.7%) comprising female and who had attained secondary level of education (86.0%). The main source of information was from television/radio. The total score for knowledge questions was 15 and practice questions were 25. A total of 60.2% attained "adequate knowledge" and 52.0% "good practice". Mean (SD) for knowledge score was 11.6 (2.3) and practice was 18.1 (4.1). Ethnicity, education, income and practice score were identified as predictors for knowledge score. Income and knowledge scores were predictors for practice score. There was positive correlation between knowledge and practice scores.

Questioning diagnoses in clinical practice: a thematic analysis of clinical psychologists' accounts of working beyond diagnosis in the United Kingdom.

PubMed

Randall-James, James; Coles, Steven

2018-02-08

The British Psychological Society proposes that clinical psychologists are well placed to move beyond psychiatric diagnoses and develop alternative practices. This study sought to explore what the application of these guiding principles looks like in clinical practice, the challenges faced and possible routes forward. A purpose-designed survey was completed by 305 respondents and a thematic analysis completed. Thematic analysis was used to identify five superordinate themes relating to individuals, relational, others, structures and society, comprising of a total of 21 group themes. The presented group themes highlight an array of approaches to practicing beyond diagnosis and factors that help and hinder such action; from scaffolding change, becoming leaders, relating to the multi-disciplinary team, restructuring services and the processes of change. A key concept was "playing the diagnostic game". "Playing the diagnostic game" enables psychologists to manage an array of tensions and anxieties: conflicts between belief and practice, relationships with colleagues, and dilemmas of position and power. It also potentially limits a concerted questioning of diagnosis and consideration of alternatives. An alternative conceptual framework for non-diagnostic practice is needed to aid the collective efforts of clinical psychologists developing their practice beyond diagnosis, some of which have been highlighted in this study. Until then, ways of mitigating the perceived threats to questioning diagnosis need further exploration, theorising and backing.

Insights into Inverse Materials Design from Phase Transitions in Shape Space

NASA Astrophysics Data System (ADS)

Cersonsky, Rose; van Anders, Greg; Dodd, Paul M.; Glotzer, Sharon C.

In designing new materials for synthesis, the inverse materials design approach posits that, given a structure, we can predict a building block optimized for self- assembly. How does that building block change as pressure is varied to maintain the same crystal structure? We address this question for entropically stabilized colloidal crystals by working in a generalized statistical thermodynamic ensemble where an alchemical potential variable is fixed and its conjugate variable, particle shape, is allowed to fluctuate. We show that there are multiple regions of shape behavior and phase transitions in shape space between these regions. Furthermore, while past literature has looked towards packing arguments for proposing shape-filling candidate building blocks for structure formation, we show that even at very high pressures, a structure will attain lowest free energy by modifying these space-filling shapes.

2010-01-01

The aim of the study was to compare the effects of 'face-to-face education' and 'educational movies' on 'knowledge' and 'practice' of women of child-bearing-age, in terms of health-care during pregnancy and during infancy in a suburban region near Tehran City, Iran. In this quasi-experimental study, the sample included 873 married women. Questionnaires for knowledge and practice assessment were designed. The women were assigned to three groups: control (group I), face-to-face education (group II), and educational movie (group III). Knowledge questionnaires were completed before and immediately after intervention. Practice questionnaires were completed before and three months after intervention. Both questionnaires consisted of two types of questions: type A (concerning infant care issues) and type B (concerning prenatal health care). There was a significant difference in post-test knowledge between groups I and II and between groups I and III, but not between groups II and III. In terms of post-test practice, the changes were determined for every individual question, and significantly, better results were seen in group II, especially concerning type B questions. Face to face education lead to better practice than educational movies. In addition, significantly better practice occurred regarding child health care issues rather than prenatal issues in both groups. Realistic and tangible issues, those easy to practice, and with little or no economical burden imposed on the family, progressed from the knowledge state to the practice state more successfully in both groups.

Reasoning, evidence, and clinical decision-making: The great debate moves forward.

2017-10-01

When the editorial to the first philosophy thematic edition of this journal was published in 2010, critical questioning of underlying assumptions, regarding such crucial issues as clinical decision making, practical reasoning, and the nature of evidence in health care, was still derided by some prominent contributors to the literature on medical practice. Things have changed dramatically. Far from being derided or dismissed as a distraction from practical concerns, the discussion of such fundamental questions, and their implications for matters of practical import, is currently the preoccupation of some of the most influential and insightful contributors to the on-going evidence-based medicine debate. Discussions focus on practical wisdom, evidence, and value and the relationship between rationality and context. In the debate about clinical practice, we are going to have to be more explicit and rigorous in future in developing and defending our views about what is valuable in human life. © 2017 John Wiley & Sons, Ltd.

Quantitative gene-gene and gene-environment mapping for leaf shape variation using tree-based models.

PubMed

Fu, Guifang; Dai, Xiaotian; Symanzik, Jürgen; Bushman, Shaun

2017-01-01

Leaf shape traits have long been a focus of many disciplines, but the complex genetic and environmental interactive mechanisms regulating leaf shape variation have not yet been investigated in detail. The question of the respective roles of genes and environment and how they interact to modulate leaf shape is a thorny evolutionary problem, and sophisticated methodology is needed to address it. In this study, we investigated a framework-level approach that inputs shape image photographs and genetic and environmental data, and then outputs the relative importance ranks of all variables after integrating shape feature extraction, dimension reduction, and tree-based statistical models. The power of the proposed framework was confirmed by simulation and a Populus szechuanica var. tibetica data set. This new methodology resulted in the detection of novel shape characteristics, and also confirmed some previous findings. The quantitative modeling of a combination of polygenetic, plastic, epistatic, and gene-environment interactive effects, as investigated in this study, will improve the discernment of quantitative leaf shape characteristics, and the methods are ready to be applied to other leaf morphology data sets. Unlike the majority of approaches in the quantitative leaf shape literature, this framework-level approach is data-driven, without assuming any pre-known shape attributes, landmarks, or model structures. © 2016 The Authors.

Knowledge, attitudes and practices of female genital mutilation/cutting among health care professionals in The Gambia: a multiethnic study.

Kaplan, Adriana; Hechavarría, Suiberto; Bernal, Mariola; Bonhoure, Isabelle

2013-09-16

Female genital mutilation/cutting (FGM/C) is a harmful traditional practice with severe consequences for the health and well-being of girls and women. Health care professionals (HCPs) are therefore expected to be aware of how to identify and manage these consequences in order to ensure that those affected by the practice receive quality health care. Moreover, their integration and legitimacy within the communities allow them to play a key role in the prevention of the practice. Nevertheless, the perception of HCPs on FGM/C has been barely explored in African contexts. This study seeks to contribute to this field of knowledge by examining the knowledge, attitudes, and practices regarding FGM/C among HCPs working in rural settings in The Gambia. A cross-sectional descriptive study was designed through a quantitative methodology, following a multiethnic approach. A pre-tested questionnaire with open and closed-ended questions was created. Forty medical students from the Community-based Medical Programme were trained to administer the questionnaire, face to face, at village health facilities in rural areas of The Gambia. A final sample of 468 HCPs included all nurse cadres and midwives. A significant proportion of Gambian HCPs working in rural areas embraced the continuation of FGM/C (42.5%), intended to subject their own daughters to it (47.2%), and reported having already performed it during their medical practice (7.6%). However, their knowledge, attitudes, and practices were shaped by sex and ethnic identity. Women showed less approval for continuation of FGM/C and higher endorsement of the proposed strategies to prevent it than men. However, it was among ethnic groups that differences were more substantial. HCPs belonging to traditionally practicing groups were more favourable to the perpetuation and medicalisation of FGM/C, suggesting that ethnicity prevails over professional identity. These findings demonstrate an urgent need to build HCP's capacities for FGM/C-related complications, through strategies adapted to their specific characteristics in terms of sex and ethnicity. A culturally and gender sensitive training programme might contribute to social change, promoting the abandonment of FGM/C, avoiding medicalisation, and ensuring accurate management of its health consequences.

Sensitivity Analysis of earth and environmental models: a systematic review to guide scientific advancement

NASA Astrophysics Data System (ADS)

Wagener, Thorsten; Pianosi, Francesca

2016-04-01

Sensitivity Analysis (SA) investigates how the variation in the output of a numerical model can be attributed to variations of its input factors. SA is increasingly being used in earth and environmental modelling for a variety of purposes, including uncertainty assessment, model calibration and diagnostic evaluation, dominant control analysis and robust decision-making. Here we provide some practical advice regarding best practice in SA and discuss important open questions based on a detailed recent review of the existing body of work in SA. Open questions relate to the consideration of input factor interactions, methods for factor mapping and the formal inclusion of discrete factors in SA (for example for model structure comparison). We will analyse these questions using relevant examples and discuss possible ways forward. We aim at stimulating the discussion within the community of SA developers and users regarding the setting of good practices and on defining priorities for future research.
