Sildenafil (Viagra) and club drug use in gay and bisexual men: the role of drug combinations and context.

PubMed

Halkitis, Perry N; Green, Kelly A

2007-06-01

Data ascertained in a study of club drug use among 450 gay and bisexual men indicate that at least one class of PDE-5 (phosphodiesterase type 5 inhibitor, sildenafil [Viagra]) is used frequently in combination with club drugs such as methamphetamine, MDMA (3,4 methylenedioxymethamphetamine [ecstasy]), ketamine, cocaine, and GHB (gamma hydroxy butyrate). Patterns of sildenafil use in combination with each of the club drugs differ among key demographics including race and age. Multivariate models, controlling for demographic factors, suggest that contextual factors are key to understanding why men mix sildenafil with club drugs, although age may still be an important issue to consider. Of particular importance is the fact that use of club drugs in combination with sildenafil is strongly associated with circuit and sex parties, where a centerpiece of these environments focuses on sexual exchange. These models imply interplay between person-level and contextual factors in explaining drug use patterns and further indicate that interventions aimed at addressing illicit substance use must carefully consider the role of environmental factors in explaining behavior.

Quantum key distribution protocol based on contextuality monogamy

Singh, Jaskaran; Bharti, Kishor; Arvind

2017-06-01

The security of quantum key distribution (QKD) protocols hinges upon features of physical systems that are uniquely quantum in nature. We explore the role of quantumness, as qualified by quantum contextuality, in a QKD scheme. A QKD protocol based on the Klyachko-Can-Binicioğlu-Shumovsky (KCBS) contextuality scenario using a three-level quantum system is presented. We explicitly show the unconditional security of the protocol by a generalized contextuality monogamy relationship based on the no-disturbance principle. This protocol provides a new framework for QKD which has conceptual and practical advantages over other protocols.

Engaging stakeholders in research carries the promise of enhancing the research relevance, transparency, and speed of getting findings into practice. By describing the context and functional aspects of stakeholder groups, like those working as community advisory boards (CABs), others can learn from these experiences and operationalize their own CABs. Our objective is to describe our experiences with diverse CABs affiliated with our community engagement group within our institution's Clinical Translational Sciences Award (CTSA). We identify key contextual elements that are important to administering CABs. A group of investigators, staff, and community members engaged in a 6-month collaboration to describe their experiences of working with six research CABs. We identified the key contextual domains that illustrate how CABS are developed and sustained. Two lead authors, with experience with CABs and identifying contextual domains in other work, led a team of 13 through the process. Additionally, we devised a list of key tips to consider when devising CABs. The final domains include (1) aligned missions among stakeholders (2) resources/support, (3) defined operational processes/shared power, (4) well-described member roles, and (5) understanding and mitigating challenges. The tips are a set of actions that support the domains. Identifying key contextual domains was relatively easy, despite differences in the respective CAB's condition of focus, overall mission, or patient demographics represented. By contextualizing these five domains, other research and community partners can take an informed approach to move forward with CAB planning and engaged research.

Finding the "Right-Size" Physical Therapy Workforce: International Perspective Across 4 Countries.

2016-10-01

Finding the "right-size" physical therapy workforce is an increasingly important issue, but it has had limited study, particularly across nations. This perspective article provides a comprehensive examination of physical therapy workforce issues across 4 countries (United States, Singapore, Portugal, and Bangladesh), which were deliberately selected to allow consideration of key contextual factors. This investigation provides a theoretical model uniquely adapted to focus on variables most likely to affect physical therapy workforce needs. This theoretical model was used to guide acquisition of public domain data across the respective countries. The data then were used to provide a contextualized interpretation about the physical therapy workforce supply (ie, physical therapists per capita) across the 4 countries in light of the following factors: indicators of physical therapy need, financial and administrative barriers affecting physical therapy access and demand, the proportion of physical therapy graduates (with varying trends over time across the countries), and the role of emigration/immigration in supply inequalities among countries of lower and higher income. In addition, both the physical therapy workforce supply and scope of practice were analyzed in the context of other related professions across the 4 countries. This international comparison indicated that there may not be a "one-size-fits-all" recommendation for physical therapy workforce supply across countries or an ideal formula for its determination. The optimal, country-specific physical therapy workforce supply appears to be affected by discipline-specific health care and contextual factors that may vary across countries, and even within the same country. This article provides a conceptual framework and basis for such contextualized evaluations of the physical therapy workforce. © 2016 American Physical Therapy Association.

Communication in acute ambulatory care.

PubMed

Dean, Marleah; Oetzel, John; Sklar, David P

2014-12-01

Effective communication has been linked to better health outcomes, higher patient satisfaction, and treatment adherence. Communication in ambulatory care contexts is even more crucial, as providers typically do not know patients' medical histories or have established relationships, conversations are time constrained, interruptions are frequent, and the seriousness of patients' medical conditions may create additional tension during interactions. Yet, health communication often unduly emphasizes information exchange-the transmission and receipt of messages leading to a mutual understanding of a patient's condition, needs, and treatments. This approach does not take into account the importance of rapport building and contextual issues, and may ultimately limit the amount of information exchanged.The authors share the perspective of communication scientists to enrich the current approach to medical communication in ambulatory health care contexts, broadening the under standing of medical communication beyond information exchange to a more holistic, multilayered viewpoint, which includes rapport and contextual issues. The authors propose a socio-ecological model for understanding communication in acute ambulatory care. This model recognizes the relationship of individuals to their environment and emphasizes the importance of individual and contextual factors that influence patient-provider interactions. Its key elements include message exchange and individual, organizational, societal, and cultural factors. Using this model, and following the authors' recommendations, providers and medical educators can treat communication as a holistic process shaped by multiple layers. This is a step toward being able to negotiate conflicting demands, resolve tensions, and create encounters that lead to positive health outcomes.

This paper is the third of three related papers exploring the ways in which the principles of Learning Organizations (LOs) could be applied in Primary Care settings at the point of service delivery. Here we provide a systematic literature review of contextual factors that either play a key role in providing a facilitative context for a Learning Practice or manifest themselves as barriers to any Practice's attempts to develop a learning culture. Core contextual conditions are identified as, first, the requirement for strong and visionary leadership. Leaders who support and develop others, ask challenging questions, are willing to be learners themselves, see possibilities and make things happen, facilitate learning environments. The second core condition is the involvement and empowerment of staff where changes grow from the willing participation of all concerned. The third prerequisite is the setting-aside of times and places for learning and reflection. This paper contributes to the wider quality improvement debate in three main ways. First, by highlighting the local contextual issues that are most likely to impact on the success or failure of a Practice's attempts to work towards a learning culture. Second, by demonstrating that the very same factors can either help or hinder depending on how they are manifest and played out in context. Third, it adds to the evidence available to support the case for LOs in health care settings.

Context and the leadership experiences and perceptions of professionals: a review of the nursing profession.

PubMed

Jefferson, Therese; Klass, Des; Lord, Linley; Nowak, Margaret; Thomas, Gail

2014-01-01

Leadership studies which focus on categorising leadership styles have been critiqued for failure to consider the lived experience of leadership. The purpose of this paper is to use the framework of Jepson's model of contextual dynamics to explore whether this framework assists understanding of the "how and why" of lived leadership experience within the nursing profession. Themes for a purposeful literature search and review, having regard to the Jepson model, are drawn from the contemporary and dynamic context of nursing. Government reports, coupled with preliminary interviews with a nurseleadership team, guided selection of contextual issues. The contextual interactions arising from managerialism, existing hierarchical models of leadership and increasing knowledge work provided insights into leadership experience in nursing, in the contexts of professional identity and changing educational and generational profiles of nurses. The authors conclude that employing a contextual frame provides insights in studying leadership experience. The author propose additions to the cultural and institutional dimensions of Jepson's model. The findings have implications for structuring and communicating key roles and policies relevant to nursing leadership. These include the need to: address perceptions around the legitimacy of current nursing leaders to provide clinical leadership; modify hierarchical models of nursing leadership; address implications of the role of the knowledge workers. Observing nursing leadership through the lens of Jepson's model of contextual dynamics confirms that this is an important way of exploring how leadership is enacted. The authors found, however, the model also provided a useful frame for considering the experience and understanding of leadership by those to be led.

Implementation science approaches for integrating eHealth research into practice and policy.

2014-07-01

To summarize key issues in the eHealth field from an implementation science perspective and to highlight illustrative processes, examples and key directions to help more rapidly integrate research, policy and practice. We present background on implementation science models and emerging principles; discuss implications for eHealth research; provide examples of practical designs, measures and exemplar studies that address key implementation science issues; and make recommendations for ways to more rapidly develop and test eHealth interventions as well as future research, policy and practice. The pace of eHealth research has generally not kept up with technological advances, and many of our designs, methods and funding mechanisms are incapable of providing the types of rapid and relevant information needed. Although there has been substantial eHealth research conducted with positive short-term results, several key implementation and dissemination issues such as representativeness, cost, unintended consequences, impact on health inequities, and sustainability have not been addressed or reported. Examples of studies in several of these areas are summarized to demonstrate this is possible. eHealth research that is intended to translate into policy and practice should be more contextual, report more on setting factors, employ more responsive and pragmatic designs and report results more transparently on issues important to potential adopting patients, clinicians and organizational decision makers. We outline an alternative development and assessment model, summarize implementation science findings that can help focus attention, and call for different types of more rapid and relevant research and funding mechanisms.

Theoretical and Methodological Considerations in Cross-Generational Research on Parenting and Child Aggressive Behavior

2015-01-01

The four studies in this special issue represent important advances in research on the intergenerational transmission of aggressive behavior. In this commentary, we review the key features and findings of these studies, as well as our own cross-generational study of aggression, the Columbia County Longitudinal Study. Next, we consider important theoretical issues (e.g., defining and operationalizing “aggression” and “parenting”; assessing reciprocal effects of parenting and child aggression; identifying the ages at which aggression should be assessed across generations; broadening the investigation of contextual and individual factors). We then discuss several methodological issues (e.g., determining the most informative measurement intervals for assessing prospective effects; sampling considerations; measuring potential moderating and mediating variables that might explain cross-generational continuities and discontinuities in parenting and aggression). Finally, we raise implications of cross-generational research for designing interventions targeting the reduction and prevention of child aggression. PMID:12735400

This paper describes an assessment of community readiness to implement a community-wide teen pregnancy prevention initiative, Youth First, and presents strategies used to enhance this readiness as informed by the assessment. Twenty-five community stakeholder interviews were conducted to assess four domains of readiness: (1) attitudes, perception, and knowledge of teen pregnancy; (2) perceived level of readiness; (3) resources, existing and current efforts; and (4) leadership. Interview transcripts were coded and analyzed to identify key themes. Stakeholders acknowledged teen pregnancy as an issue but lacked contextual information. They also perceived the community as ready to address the issue and recognized some organizations already championing efforts. However, many key players were not involved, and ongoing data collection to assess teen pregnancy and prevention efforts was limited. Though many stakeholders were ready to engage in teen pregnancy prevention efforts, they required additional information and training to appropriately address the issue. In response to the assessment findings, several strategies were applied to address readiness and build Youth First partners' capacity to implement the community-wide initiative. Thus, to successfully implement community-wide prevention efforts, it is valuable to assess the level of community readiness to address health issues.

Despite the growing number of culturally sensitive training models and considerable literature on the importance of training clinicians in larger contextual issues, research examining how students learn to apply these issues is limited. In this participatory action research project, we systematically studied our own process as marriage and family therapy (MFT) practicum students developing a contextual consciousness. Using grounded theory, we identified a three-stage process: (a) raised awareness through clinical experimentation and developing a theoretical rationale, (b) reflective questioning involving challenging old perspectives and experiencing positive client-therapist interactions, and (c) an intentional new lens based on personal responsibility and commitment. Creating and maintaining a contextual lens required a safe, empowering group dynamic and accessing other forms of support and accountability after the practicum. © 2012 American Association for Marriage and Family Therapy.

2016-02-01

This study examined Latin American evaluation needs regarding the development of a collaborative mental health care (CMHC) evaluation framework as seen by local key health-care leaders and professionals. Potential implementation challenges and opportunities were also identified. This multisite research study used an embedded mixed methods approach in three public health networks in Mexico, Nicaragua and Chile. Local stakeholders participated: decision-makers in key informant interviews, front-line clinicians in focus groups and other stakeholders through a survey. The analysis was conducted within site and then across sites. A total of 22 semi-structured interviews, three focus groups and 27 questionnaires (52% response rate) were conducted. Participants recognized a strong need to evaluate different areas of CMHC in Latin America, including access, types and quality of services, human resources and outcomes related to mental disorders, including addiction. A priority was to evaluate collaboration within the health system, including the referral system. Issues of feasibility, including the weaknesses of information systems, were also identified. Local stakeholders strongly supported the development of a comprehensive evaluation framework for CMHC in Latin America and cited several dimensions and contextual factors critical for inclusion. Implementation must allow flexibility and adaptation to the local context. © 2015 John Wiley & Sons Ltd.

Who am I? Key influences on the formation of academic identity within a faculty development program.

Professional identity encompasses how individuals understand themselves, interpret experiences, present themselves, wish to be perceived, and are recognized by the broader professional community. For health professional and health science educators, their 'academic' professional identity is situated within their academic community and plays an integral role in their well being and productivity. This study aims to explore factors that contribute to the formation and growth of academic identity (AI) within the context of a longitudinal faculty development program. Using a qualitative case study approach, data from three cohorts of a 2-year faculty development program were explored and analyzed for emerging issues and themes related to AI. Factors salient to the formation of AI were grouped into three major domains: personal (cognitive and emotional factors unique to each individual); relational (connections and interactions with others); and contextual (the program itself and external work environments). Faculty development initiatives not only aim to develop knowledge, skills, and attitudes, but also contribute to the formation of academic identities in a number of different ways. Facilitating the growth of AI has the potential to increase faculty motivation, satisfaction, and productivity. Faculty developers need to be mindful of factors within the personal, relational, and contextual domains when considering issues of program design and implementation.

Contextual Fear Conditioning in Humans: Cortical-Hippocampal and Amygdala Contributions

Alvarez, Ruben P.; Biggs, Arter; Chen, Gang; Pine, Daniel S.; Grillon, Christian

2008-01-01

Functional imaging studies of cued fear conditioning in humans have largely confirmed findings in animals, but it is unclear whether the brain mechanisms that underlie contextual fear conditioning in animals are also preserved in humans. We investigated this issue using fMRI and virtual reality contexts. Subjects underwent differential context conditioning in which they were repeatedly exposed to two contexts (CXT+ and CXT-) in semi-random order, with contexts counterbalanced across participants. An un-signaled footshock was consistently paired with the CXT+, and no shock was ever delivered in the CXT-. Evidence for context conditioning was established using skin conductance and anxiety ratings. Consistent with animal models centrally implicating the hippocampus and amygdala in a network supporting context conditioning, CXT+ compared to CXT- significantly activated right anterior hippocampus and bilateral amygdala. In addition, context conditioning was associated with activation in posterior orbitofrontal cortex, medial dorsal thalamus, anterior insula, subgenual anterior cingulate, and parahippocampal, inferior frontal and parietal cortices. Structural equation modeling was used to assess interactions among the core brain regions mediating context conditioning. The derived model indicated that medial amygdala was the source of key efferent and afferent connections including input from orbitofrontal cortex. These results provide evidence that similar brain mechanisms may underlie contextual fear conditioning across species. PMID:18550763

In recognition of the level of international HIV/AIDS research being conducted by Canadians, the Canadian Association for HIV Research (CAHR), along with its partners, has developed a resource document to assist researchers in identifying and preparing for the unique ethics issues and challenges that may arise during international HIV/AIDS research. Between 2004 and 2007, face-to-face consultations were undertaken with community and government stakeholders, and interviews were conducted with eight prominent HIV/AIDS researchers with international experience to identify key research ethics challenges and structural, cultural, political, social, and economic factors that may impact HIV/AIDS research ethics in resource-limited settings. These challenges and factors served as the basis for the hypothetical ethics issues case scenarios developed for each of the four research tracks. Ethics issues were identified at every stage of the research process. Key contextual issues included: (1) stigma and culturally-embedded conceptualizations of HIV; (2) local and global politics and economics; (3) gender inequities, power dynamics, and sexual roles; and (4) allocation and availability of resources for research and health services. The final document resulting from the consultation process provides a framework for open dialogue on the complex and interconnected ethics issues researchers may experience in the field of international HIV/AIDS research, and contributes to the HIV/AIDS research field by reinforcing the need for high quality and ethically sound research.

Context is everything: From cardiovascular disease to cerebral microbleeds.

Charidimou, Andreas; Blacker, Deborah; Viswanathan, Anand

2018-01-01

Increasingly, our approach to cerebrovascular disease has become blurred by evidence published in literature often without careful consideration of what this evidence implies for specific patients at hand. In this essay, we analyze key contextual issues in cerebrovascular small vessel disease, in an attempt to highlight the symbolic gap that exists between research and clinical practice, a recurring theme in medicine. We highlight the importance of considering context when using data from epidemiologic, neuroimaging, and biomarker studies in determining relevance to the patient at hand. We argue, that while biomarkers and neuroimaging may eventually serve to help to identify individuals with specific cerebrovascular diseases, we must always continue to understand patients in a specific clinical context. These reflections are particularly relevant when considering cerebral microbleeds-a key marker of cerebrovascular small vessel disease whose detection often raises thorny clinical dilemmas.

Exploring the role of contextual information in bloodstain pattern analysis: A qualitative approach.

PubMed

Osborne, Nikola K P; Taylor, Michael C; Zajac, Rachel

2016-03-01

During Bloodstain Pattern Analysis (BPA), an analyst may encounter various sources of contextual information. Although contextual bias has emerged as a valid concern for the discipline, little is understood about how contextual information informs BPA. To address this issue, we asked 15 experienced bloodstain pattern analysts from New Zealand and Australia to think aloud as they classified bloodstain patterns from two homicide cases. Analysts could request items of contextual information, and were required to state how each item would inform their analysis. Pathology reports and additional photographs of the scene were the most commonly requested items of information. We coded analysts' reasons for requesting contextual information--and the way in which they integrated this information--according to thematic analysis. We identified considerable variation in both of these variables, raising important questions about the role and necessity of contextual information in decisions about bloodstain pattern evidence.

Impact of community capacity on the health status of residents: understanding with the contextual multilevel model.

PubMed

Jung, Minsoo; Choi, Mankyu

2013-01-01

There has been little conceptual understanding as to how community capacity works, although it allows for an important, population-based health promotional strategy. In this study, the mechanism of community capacity was studied through literature reviews to suggest a comprehensive conceptual model. The research results found that the key to community capacity prevailed in how actively the capacities of individuals and their communities are able to interact with one another. Under active interactions, community-based organizations, which are a type of voluntary association, were created within the community, and cohesion among residents was enhanced. In addition, people were more willing to address community issues. During the process, many services were initiated to meet the people's health needs and strengthen their social and psychological ties. The characteristics of community capacity were named as the contextual multilevel effects. Because an increase in community capacity contributes to a boosted health status, encourages health behaviors, and eventually leads to the overall prosperity of the community, more public health-related attention is required.

Contextual classification of multispectral image data: An unbiased estimator for the context distribution

1981-01-01

A key input to a statistical classification algorithm, which exploits the tendency of certain ground cover classes to occur more frequently in some spatial context than in others, is a statistical characterization of the context: the context distribution. An unbiased estimator of the context distribution is discussed which, besides having the advantage of statistical unbiasedness, has the additional advantage over other estimation techniques of being amenable to an adaptive implementation in which the context distribution estimate varies according to local contextual information. Results from applying the unbiased estimator to the contextual classification of three real LANDSAT data sets are presented and contrasted with results from non-contextual classifications and from contextual classifications utilizing other context distribution estimation techniques.

Compelling science questions and critical resources make the Moon a key destination for future human and robotic exploration. Lunar surface exploration, including rovers and other landed missions, must be part of a balanced planetary science and exploration portfolio. Among the highest planetary exploration priorities is the collection of new samples and their return to Earth for more comprehensive analysis than can be done in-situ. The Moon is the closest and most accessible location to address key science questions through targeted sample return. The Moon is the only other planet from which we have contextualized samples, yet critical issues need to be addressed: we lack important details of the Moon's early and recent geologic history, the full compositional and age ranges of its crust, and its bulk composition.

Contextual behavior and neural circuits

PubMed Central

Lee, Inah; Lee, Choong-Hee

2013-01-01

Animals including humans engage in goal-directed behavior flexibly in response to items and their background, which is called contextual behavior in this review. Although the concept of context has long been studied, there are differences among researchers in defining and experimenting with the concept. The current review aims to provide a categorical framework within which not only the neural mechanisms of contextual information processing but also the contextual behavior can be studied in more concrete ways. For this purpose, we categorize contextual behavior into three subcategories as follows by considering the types of interactions among context, item, and response: contextual response selection, contextual item selection, and contextual item–response selection. Contextual response selection refers to the animal emitting different types of responses to the same item depending on the context in the background. Contextual item selection occurs when there are multiple items that need to be chosen in a contextual manner. Finally, when multiple items and multiple contexts are involved, contextual item–response selection takes place whereby the animal either chooses an item or inhibits such a response depending on item–context paired association. The literature suggests that the rhinal cortical regions and the hippocampal formation play key roles in mnemonically categorizing and recognizing contextual representations and the associated items. In addition, it appears that the fronto-striatal cortical loops in connection with the contextual information-processing areas critically control the flexible deployment of adaptive action sets and motor responses for maximizing goals. We suggest that contextual information processing should be investigated in experimental settings where contextual stimuli and resulting behaviors are clearly defined and measurable, considering the dynamic top-down and bottom-up interactions among the neural systems for contextual behavior.

Information Issues and Contexts that Impair Team Based Communication Workflow: A Palliative Sedation Case Study.

PubMed

Cornett, Alex; Kuziemsky, Craig

2015-01-01

Implementing team based workflows can be complex because of the scope of providers involved and the extent of information exchange and communication that needs to occur. While a workflow may represent the ideal structure of communication that needs to occur, information issues and contextual factors may impact how the workflow is implemented in practice. Understanding these issues will help us better design systems to support team based workflows. In this paper we use a case study of palliative sedation therapy (PST) to model a PST workflow and then use it to identify purposes of communication, information issues and contextual factors that impact them. We then suggest how our findings could inform health information technology (HIT) design to support team based communication workflows.

University students as recipients of and contributors to information on climate change: insights from South Africa and implications for well-being.

PubMed

El Zoghbi, Mona Betour; El Ansari, Walid

2014-06-01

This study aimed to enhance the in-depth understanding of the contextual dimensions that shape the relationships between climate change communication approach and youth well-being. The study focused on university students who constitute the key stakeholders and future decision-makers and leaders for managing the long-term climate risks. A total of 10 focus group interviews were conducted with 117 undergraduate and graduate South African university students from over 12 universities located in different provinces of South Africa. In addition, another 16 interviews were also undertaken with university students, 10 interviews with key experts, and 3 youth national events were attended as participant-observation. As recipients of information on climate change, students' well-being was negatively affected by the media's pessimism of communicating risks and the inadequate or restricted networking of communicating solutions and strategies. As contributors to information on climate change, students faced key barriers to their efficacy and agency that entailed socio-cultural inequalities (e.g. race and language) and a lack of formal forums for community recognition, policy consultation and collaboration. In addition, for some students (e.g. journalism students), the lack of sufficient knowledge and skills on climate change and sustainability issues limited their ability to effectively communicate these issues to their audience. Platforms for interactive and reflective discussions, access to innovative technologies and social media, and opportunities for multi-stakeholder partnerships are keys to the success of youth-targeted and youth-initiated communication on climate change.

Human capital flight challenges within an equitable health system.

PubMed

Udonwa, N E

2007-01-01

The issue of human capital flight has been discussed at different forums with a consensus opinion that it has its merits and demerits to equitable health system. Most often one nation becomes a substantial net exporter of talent, leaving the provider nation at risk of depleting its natural supply of talent. This paper looks into the historical perspective of human capital flight or "brain drain", and its burden. It attempts to elucidate the various causes and suggested solutions. The paper's objective is to educate colleagues on the conceptual and contextual imperatives of the issue. Using a convenient sample of key informants who were medical colleagues in Nigeria relevant information was sourced from these colleagues, documents from the postgraduate medical college of Nigeria and the internet on maters relating to human capital flight and brain drain. Every year, thousands of qualified doctors, and other professionals leave Nigeria tempted by significantly higher wages, brighter prospects for employment and education, stability, food security. It appears that the potential exposure to different working conditions, resources and professional environments can be of advantage to the country, should Nigeria be able to recall these professionals. It also appears that necessary economic reforms that make staying at home rewarding, that is--good leadership, and policy planning that seriously looks into rural development, among other issues, are keys ingredients to reversing the trend in order to ensure a more equitable health system.

Contextual cost: when a visual-search target is not where it should be.

PubMed

Makovski, Tal; Jiang, Yuhong V

2010-02-01

Visual search is often facilitated when the search display occasionally repeats, revealing a contextual-cueing effect. According to the associative-learning account, contextual cueing arises from associating the display configuration with the target location. However, recent findings emphasizing the importance of local context near the target have given rise to the possibility that low-level repetition priming may account for the contextual-cueing effect. This study distinguishes associative learning from local repetition priming by testing whether search is directed toward a target's expected location, even when the target is relocated. After participants searched for a T among Ls in displays that repeated 24 times, they completed a transfer session where the target was relocated locally to a previously blank location (Experiment 1) or to an adjacent distractor location (Experiment 2). Results revealed that contextual cueing decreased as the target appeared farther away from its expected location, ultimately resulting in a contextual cost when the target swapped locations with a local distractor. We conclude that target predictability is a key factor in contextual cueing.

Predictive codes of familiarity and context during the perceptual learning of facial identities

NASA Astrophysics Data System (ADS)

Apps, Matthew A. J.; Tsakiris, Manos

2013-11-01

Face recognition is a key component of successful social behaviour. However, the computational processes that underpin perceptual learning and recognition as faces transition from unfamiliar to familiar are poorly understood. In predictive coding, learning occurs through prediction errors that update stimulus familiarity, but recognition is a function of both stimulus and contextual familiarity. Here we show that behavioural responses on a two-option face recognition task can be predicted by the level of contextual and facial familiarity in a computational model derived from predictive-coding principles. Using fMRI, we show that activity in the superior temporal sulcus varies with the contextual familiarity in the model, whereas activity in the fusiform face area covaries with the prediction error parameter that updated facial familiarity. Our results characterize the key computations underpinning the perceptual learning of faces, highlighting that the functional properties of face-processing areas conform to the principles of predictive coding.

Determinants and consequences of health worker motivation in hospitals in Jordan and Georgia.

PubMed

Franco, Lynne Miller; Bennett, Sara; Kanfer, Ruth; Stubblebine, Patrick

2004-01-01

Health worker motivation reflects the interactions between workers and their work environment. Because of the interactive nature of motivation, local organizational and broader sector policies have the potential to affect motivation of health workers, either positively or negatively, and as such to influence health system performance. Yet little is known about the key determinants and outcomes of motivation in developing and transition countries. This exploratory research, unique in its broader study of a whole range of motivational determinants and outcomes, was conducted in two hospitals in Jordan and two in Georgia. Three complementary approaches to data collection were used: (1) a contextual analysis; (2) a qualitative 360-degree assessment; and (3) a quantitative in-depth analysis focused on the individual determinants and outcomes of the worker's motivational process. A wide range of psychometric scales was used to assess personality differences, perceived contextual factors and motivational outcomes (feelings, thoughts and behaviors) on close to 500 employees in each country. Although Jordan and Georgia have very different cultural and socio-economic environments, the results from these two countries exhibited many similarities among key determinants: self-efficacy, pride, management openness, job properties, and values had significant effects on motivational outcomes in both countries. Where results were divergent, differences between the two countries highlight the importance of local culture on motivational issues, and the need to tailor motivational interventions to the specific issues related to particular professional or other groupings in the workforce. While workers themselves state that financial reward is critical for their work satisfaction, the data suggest a number of non-financial interventions that may be more effective means to improve worker motivation. This research highlights the complexity of worker motivation, and the need for a more comprehensive approach to increasing motivation, satisfaction and performance, and for interventions at both organizational and policy levels.

Rapid Ethical Assessment on Informed Consent Content and Procedure in Hintalo-Wajirat, Northern Ethiopia: A Qualitative Study.

Informed consent is a key component of bio-medical research involving human participants. However, obtaining informed consent is challenging in low literacy and resource limited settings. Rapid Ethical Assessment (REA) can be used to contextualize and simplify consent information within a given study community. The current study aimed to explore the effects of social, cultural, and religious factors during informed consent process on a proposed HPV-serotype prevalence study. A qualitative community-based REA was conducted in Adigudom and Mynebri Kebeles, Northern Ethiopia, from July to August 2013. Data were collected by a multi-disciplinary team using open ended questions concerning informed consent components in relation to the parent study. The team conducted one-to-one In-Depth Interviews (IDI) and Focus Group Discussions (FGDs) with key informants and community members to collect data based on the themes of the study. Tape recorded data were transcribed in Tigrigna and then translated into English. Data were categorized and thematically analyzed using open coding and content analysis based on pre-defined themes. The REA study revealed a number of socio-cultural issues relevant to the proposed study. Low community awareness about health research, participant rights and cervical cancer were documented. Giving a vaginal sample for testing was considered to be highly embarrassing, whereas giving a blood sample made participants worry that they might be given a result without the possibility of treatment. Verbal consent was preferred to written consent for the proposed study. This rapid ethical assessment disclosed important socio-cultural issues which might act as barriers to informed decision making. The findings were important for contextual modification of the Information Sheet, and to guide the best consent process for the proposed study. Both are likely to have enabled participants to understand the informed consent better and consequently to comply with the study.

Lakes, Kimberley D; Vaughan, Elaine; Lemke, Amy; Jones, Marissa; Wigal, Timothy; Baker, Dean; Swanson, James M; Burke, Wylie

2013-01-01

The objectives of this study were to study maternal preferences for the return of their child's genetic results and to describe the experiences, perceptions, attitudes, and values that are brought to bear when individuals from different racial and cultural backgrounds consider participating in genetic research. We recruited women with diverse sociodemographic profiles to participate in seven focus groups. Twenty-eight percent of participants self-identified as Hispanic; 49% as White, non-Hispanic; and 21% as Asian or Asian American. Focus groups were conducted in English or Spanish and were audio-recorded and transcribed verbatim. Transcripts were analyzed using qualitative thematic methods. Results indicated that preferences and decisions regarding the return of results may depend on both research and individual contextual factors. Participants understood the return of results as a complex issue, where individual and cultural differences in preferences are certain to arise. Another key finding was that participants desired an interpersonal, dynamic, flexible process that accommodated individual preferences and contextual differences for returning results. Our findings indicate a need to have well-developed systems for allowing participants to make and change over time their choices regarding the return of their child's genetic results.

Developing, implementing and evaluating OSH interventions in SMEs: a pilot, exploratory study.

PubMed

Masi, Donato; Cagno, Enrico; Micheli, Guido J L

2014-01-01

The literature on occupational safety and health (OSH) interventions contains many debates on how interventions should work, but far less attention has been paid to how they actually do work, and to the contextual factors that influence their implementation, development and effect. The need of improving the understanding of the OSH interventions issue is particularly relevant for small and medium-sized enterprises (SMEs), since they experience worse OSH conditions, and have fewer physical, economic and organizational resources if compared to larger enterprises; thus, SMEs strongly need to focus their few resources in the decision-making process so as to select and put in place only the most proper interventions. This exploratory study is based on interviews with safety officers of 5 SMEs, and it gives an overview of the key features of the actual intervention process in SMEs and of the contextual factors making this actual intervention process similar or dissimilar to the ideal case. The results show how much qualitative and experience driven the actual intervention process is; they should be used to direct the future research towards an increasingly applicable one, to enable practitioners from SMEs to develop, implement and evaluate their OSH interventions in an "ideal" way.

Rethinking forest carbon assessments to account for policy institutions

NASA Astrophysics Data System (ADS)

Macintosh, Andrew; Keith, Heather; Lindenmayer, David

2015-10-01

There has been extensive debate about whether the sustainable use of forests (forest management aimed at producing a sustainable yield of timber or other products) results in superior climate outcomes to conservation (maintenance or enhancement of conservation values without commercial harvesting). Most of the relevant research has relied on consequential life-cycle assessment (LCA), with the results tending to show that sustainable use has lower net greenhouse-gas (GHG) emissions than conservation in the long term. However, the literature cautions that results are sensitive to forest- and market-related contextual factors: the carbon density of the forests, silvicultural and wood processing practices, and the extent to which wood products and forest bioenergy displace carbon-intensive alternatives. Depending on these issues, conservation can be better for the climate than sustainable use. Policy institutions are another key contextual factor but, so far, they have largely been ignored. Using a case study on the Southern Forestry Region (SFR) of New South Wales (NSW), Australia, we show how policy institutions can affect the assessed outcomes from alternative forest management strategies. Our results highlight the need for greater attention to be paid to policy institutions in forest carbon research.

Contextual and interdependent causes of climate change adaptation barriers: Insights from water management institutions in Himachal Pradesh, India.

PubMed

Azhoni, Adani; Holman, Ian; Jude, Simon

2017-01-15

Research on adaptation barriers is increasing as the need for climate change adaptation becomes evident. However, empirical studies regarding the emergence, causes and sustenance of adaptation barriers remain limited. This research identifies key contextual causes of adaptation barriers in water institutions in the mountainous Himalayan state of Himachal Pradesh in northern India. Semi-structured interviews were carried out with representatives from twenty-six key governmental, non-governmental, academic and research institutions in the State with responsibilities spanning domestic water supply, irrigation and hydropower generation, environmental monitoring and research. It identified low knowledge capacity and resources, policy implementation gaps, normative attitudes, and unavailability and inaccessibility of data and information compounded with weak interinstitutional networks as key adaptation barriers. Although these barriers are similar to those reported elsewhere, they have important locally-contextual root causes. For instance, inadequate resources result from fragmented resources allocation due to competing developmental priorities and the desire of the political leadership to please diverse electors, rather than climate scepticism. The identified individual barriers are found to be highly inter-dependent and closely intertwined which enables the identification of leverage points for interventions to maximise barrier removal. For instance, breaking down key barriers hindering accessibility to data and information, which are shaped by systemic bureaucracies and cultural attitudes, will involve attitudinal change through sensitisation to the importance of accurate and accessible data and information and the building trust between different actors, in addition to institutional structural changes through legislation and inter-institutional agreements. Approaching barriers as a system of contextually interconnected cultural, systemic, geographical and political underlying factors enriches the understanding of adaptation enablers, thereby contributing to achieving a better adapted society.

In 1808, Dom João VI issued an edict which regulated the shipping and treatment of slaves on the transatlantic crossing from Africa. Two years later, Antonio de Saldanha da Gama, a member of the Treasury Council, drafted a letter discussing some points of the resolution. This key figure in the Portuguese administration of Brazil argued that his respectful considerations concerning the determinations of His Royal Highness were designed to improve them "for humanitarian and economic reasons." Safeguarded in the archives of Arquivo Histórico Ultramarino, this letter is transcribed, annotated, and contextualized here, supplying an interesting perspective on the prevailing concerns and justifications about the trafficking of African slaves to Brazil.

Selecting team players: Considering the impact of contextual performance and workplace deviance on selection decisions in the National Football League.

PubMed

Whiting, Steven W; Maynes, Timothy D

2016-04-01

Contextual performance and workplace deviance likely influence team functioning and effectiveness and should therefore be considered when evaluating job candidates for team-based roles. However, obtaining this information is difficult given a lack of reliable sources and the desire of job applicants to present themselves in a favorable light. Thus, it is unknown whether those selecting employees for teams incorporate prior contextual performance and workplace deviance into their evaluations, or whether doing so improves the quality of selection decisions. To address these issues, we examined the impact of prior task performance, contextual performance, and workplace deviance on National Football League (NFL) decision maker (organizational insider) and external expert (organizational outsider) evaluations of college football players in the NFL draft, using a content analysis methodology to generate measures of contextual performance and workplace deviance. Our findings indicate that insiders value contextual performance more than outsiders, which is likely because of differing interests and goals that lead to different levels of motivation and/or ability to acquire information about prior contextual performance. We also propose that prior task performance, contextual performance, and workplace deviance will predict player performance in the NFL. Our results support this prediction for task and contextual performance. In addition, we investigated the quality of insider and outsider judgments using Brunswik's (1952) lens model. Implications of our findings for the team selection, contextual performance, and workplace deviance literatures are discussed. (c) 2016 APA, all rights reserved).

Race and the Religious Contexts of Violence: Linking Religion and White, Black, and Latino Violent Crime

PubMed Central

Ulmer, Jeffery T.; Harris, Casey T.

2014-01-01

Research has demonstrated that concentrated disadvantage and other measures are strongly associated with aggregate-level rates of violence, including across racial and ethnic groups. Less studied is the impact of cultural factors, including religious contextual measures. The current study addresses several key gaps in prior literature by utilizing race/ethnic-specific arrest data from California, New York, and Texas paired with religious contextual data from the Religious Congregations and Memberships Survey (RCMS). Results suggest that, net of important controls, (1) religious contextual measures have significant crime-reducing associations with violence, (2) these associations are race/ethnic-specific, and (3) religious contextual measures moderate the criminogenic association between disadvantage and violence for Blacks. Implications for future research are discussed. PMID:24976649

Health systems are increasingly focusing on the issue of 'overuse' of health services and how to address it. We developed a framework focused on (1) the rationale and context for health systems prioritising addressing overuse, (2) elements of a comprehensive process and approach to reduce overuse and (3) implementation considerations for addressing overuse. We conducted a critical interpretive synthesis informed by a stakeholder-engagement process. The synthesis identified relevant empirical and non-empirical articles about system-level overuse. Two reviewers independently screened records, assessed for inclusion and conceptually mapped included articles. From these, we selected a purposive sample, created structured summaries of key findings and thematically synthesised the results. Our search identified 3545 references, from which we included 251. Most articles (76%; n = 192) were published within 5 years of conducting the review and addressed processes for addressing overuse (63%; n = 158) or political and health system context (60%; n = 151). Besides negative outcomes at the patient, system and global level, there were various contextual factors to addressing service overuse that seem to be key issue drivers. Processes for addressing overuse can be grouped into three elements comprising a comprehensive approach, including (1) approaches to identify overused health services, (2) stakeholder- or patient-led approaches and (3) government-led initiatives. Key implementation considerations include the need to develop 'buy in' from stakeholders and citizens. Health systems want to ensure the use of high-value services to keep citizens healthy and avoid harm. Our synthesis can be used by policy-makers, stakeholders and researchers to understand how the issue has been prioritised, what approaches have been used to address it and implementation considerations.

Onjong, Hillary Adawo; Wangoh, John; Njage, Patrick Murigu Kamau

2014-10-01

Fish-processing plants still face food safety (FS) challenges worldwide despite the existence of several quality assurance standards and food safety management systems/s (FSMSs). This study assessed performance of FSMS in fish exporting sector considering pressure from the context in which they operate. A FSMS diagnostic tool with checklist was used to assess the context, FSMS, and FS output in 9 Kenyan fish exporting companies. Majority (67%) companies operated at moderate- to high-risk context but with an average performance in control and assurance activities. This situation could be insufficient to deal with ambiguity, uncertainty, and vulnerability issues in the context characteristics. Contextual risk posed by product characteristics (nature of raw materials) and chain environment characteristics was high. Risk posed by the chain environment characteristics, low power in supplier relationships, and low degree of authority in customer relationships was high. Lack of authority in relationship with suppliers would lead to high raw material risk situation. Even though cooling facilities, a key control activity, was at an advanced level, there was inadequate packaging intervention equipment which coupled with inadequate physical intervention equipment could lead to further weakened FSMS performance. For the fish companies to improve their FSMS to higher level and enhance predictability, they should base their FSMS on scientific information sources, historical results, and own experimental trials in their preventive, intervention, and monitoring systems. Specific suggestions are derived for improvements toward higher FSMS activity levels or lower risk levels in context characteristics. Weak areas in performance of control and assurance activities in export fish-processing sector already implementing current quality assurance guidelines and standards were studied taking into consideration contextual pressure wherein the companies operate. Important mitigation measures toward improved contextual risk, core assurance, and control activities irrespective of applied food safety management systems in fish industries were suggested. © 2014 Institute of Food Technologists®

As a minority ethnic group, Native Hawaiian youth and young adults face an array of issues associated with colonization, such as persistent structural discrimination and the loss of land and indigenous ways of knowing. They are also at risk for a wide range of negative behaviors, including interpersonal violence, suicide, substance use, and juvenile delinquency. This article explores how community youth development, critical pedagogies, and Hawaiian epistemology can help Native Hawaiian young adults cope with such issues. It begins with a brief discussion of critiques on conventional youth violence prevention programs. To address these critiques, three bodies of literature are introduced: 1) community youth development, 2) critical pedagogy, and 3) community epistemology. Data were derived from a single case study of a community-based youth program. The program, located in an impoverished, rural community in Hawai‘i, entailed running an organic farm. Seventeen participants were involved in the study. Semi-structured interviews were used to collect data. Utilizing critical indigenous qualitative research, a content analysis of the interviews was conducted to build a working conceptual model. Preliminary findings suggest that a program with key processes of community youth development, critical pedagogies, and Hawaiian epistemology may serve as a vehicle for health and wellness, thus preventing a host of negative behaviors, such as violence. Based on the findings, a critical contextually based approach to violence prevention that focuses on providing opportunities for Native Hawaiian young adults to take an active participatory role in promoting health is proposed.

Implementing complex and multi-level public health programmes is challenging in school settings. Discrepancies between expected and actual programme outcomes are often reported. Such discrepancies are due to complex interactions between contextual factors. Contextual factors relate to the setting, the community, in which implementation occurs, the stakeholders involved, and the characteristics of the programme itself. This work uses realist evaluation to understand how contextual factors influence the implementation process, to result in variable programme outcomes. This study focuses on identifying contextual factors, pinpointing combinations of contextual factors, and understanding interactions and effects of such factors and combinations on programme outcomes on different levels of the implementation process. Schools which had participated in a school-based health promotion programme between 2012 and 2015 were included. Two sets of qualitative data were collected: semi-structured interviews with school staff and programme coordinators; and written documents about the actions implemented in a selection of four schools. Quantitative data included 1553 questionnaires targeting pupils aged 8 to 11 in 14 schools to describe the different school contexts. The comparison between what was expected from the programme (programme theory) and the outcomes identified in the field data, showed that some of the mechanisms expected to support the implementation of the programme, did not operate as anticipated (e.g. inclusion of training, initiation by decision-maker). Key factors which influenced the implementation process included, amongst other factors, the mode of introduction of the programme, home/school relationship, leadership of the management team, and the level of delegated power. Five types of interactions between contextual factors were put forward: enabling, hindering, neutral, counterbalancing and moderating effects. Recurrent combinations of factors were identified. Implementation was more challenging in vulnerable schools where school climate was poor. A single programme cannot be suited or introduced in the same manner in every context. However, key recurrent combinations of contextual factors could contribute to the design of implementation patterns, which could provide guidelines and recommendation for grass-root programme implementation.

Introduction to the Special Issue on Visual Working Memory

Wolfe, Jeremy M

2014-01-01

Objects are not represented individually in visual working memory (VWM), but in relation to the contextual information provided by other memorized objects. We studied whether the contextual information provided by the spatial configuration of all memorized objects is viewpoint-dependent. We ran two experiments asking participants to detect changes in locations between memory and probe for one object highlighted in the probe image. We manipulated the changes in viewpoint between memory and probe (Exp. 1: 0°, 30°, 60°; Exp. 2: 0°, 60°), as well as the spatial configuration visible in the probe image (Exp. 1: full configuration, partial configuration; Exp. 2: full configuration, no configuration). Location change detection was higher with the full spatial configuration than with the partial configuration or with no spatial configuration at viewpoint changes of 0°, thus replicating previous findings on the nonindependent representations of individual objects in VWM. Most importantly, the effect of spatial configurations decreased with increasing viewpoint changes, suggesting a viewpoint-dependent representation of contextual information in VWM. We discuss these findings within the context of this special issue, in particular whether research performed within the slots-versus-resources debate and research on the effects of contextual information might focus on two different storage systems within VWM.

The fully automated analysis of 3D point clouds is of great importance in photogrammetry, remote sensing and computer vision. For reliably extracting objects such as buildings, road inventory or vegetation, many approaches rely on the results of a point cloud classification, where each 3D point is assigned a respective semantic class label. Such an assignment, in turn, typically involves statistical methods for feature extraction and machine learning. Whereas the different components in the processing workflow have extensively, but separately been investigated in recent years, the respective connection by sharing the results of crucial tasks across all components has not yet been addressed. This connection not only encapsulates the interrelated issues of neighborhood selection and feature extraction, but also the issue of how to involve spatial context in the classification step. In this paper, we present a novel and generic approach for 3D scene analysis which relies on (i) individually optimized 3D neighborhoods for (ii) the extraction of distinctive geometric features and (iii) the contextual classification of point cloud data. For a labeled benchmark dataset, we demonstrate the beneficial impact of involving contextual information in the classification process and that using individual 3D neighborhoods of optimal size significantly increases the quality of the results for both pointwise and contextual classification.

Positive change: connecting the virtual and the real.

PubMed

Wiederhold, Brenda K; Riva, Giuseppe

2014-01-01

How do we lastingly change our lives for the better? There is not an easy answer to this question. However, due to the advances in psychology and neuroscience, now we have a better view of personal change, that is not limited to a specific viewpoint. In particular, the emergence of integrative and transdiagnostic accounts suggests that change is contextual, depending on the person, the issues, and the situation. More, personal change is a process, happening in discontinuous and nonlinear ways, following life transitions and traumatic events. In this process a key role can be played by technology: using the "Positive Technology" approach it is possible to use technology to manipulate the quality of experience, with the goal of increasing wellness, and generating strengths and resilience in individuals, organizations and society.

Comparative analysis of dietary guidelines in the Spanish-Speaking Caribbean.

Fuster, Melissa

2016-03-01

Dietary guidelines are important education and policy tools to address local nutrition concerns. The current paper presents a comparative analysis of nutrition messages from three Spanish-speaking Caribbean countries (Cuba, Puerto Rico and Dominican Republic) to explore how these dietary guidelines address common public health nutrition concerns, contextualized in different changing food environments and food culture similarities. Qualitative, comparative analysis of current dietary guideline documents and key recommendations. Key recommendations were categorized into sixteen themes (two diet-based, ten food-based and four 'other'). Only the Cuban dietary guidelines included diet-based key recommendations. Of the ten food-based key recommendations, only four themes overlapped across the three dietary guidelines (the encouragement of fruits and vegetables, addressing protein sources and fat). Other overlaps were found between dietary guideline pairs, except between Cuba and Puerto Rico. Further analysis revealed differences in levels of specificity and acknowledgement of local dietary patterns and issues, as well as the need to revise the guidelines to account for current scientific advances. The present study underscored the importance of context in the framing of dietary advice and the influence of national socio-economic and political situations on nutrition policy and education efforts. The results contribute to inform efforts to improve nutrition communication in the region and among migrant communities.

Repeated pairings of a particular visual context with a specific location of a target stimulus facilitate target search in humans. We explored an animal model of this contextual cueing effect using a novel Cueing-Miscueing design. Pigeons had to peck a target which could appear in one of four possible locations on four possible color backgrounds or four possible color photographs of real-world scenes. On 80% of the trials, each of the contexts was uniquely paired with one of the target locations; on the other 20% of the trials, each of the contexts was randomly paired with the remaining target locations. Pigeons came to exhibit robust contextual cueing when the context preceded the target by 2s, with reaction times to the target being shorter on correctly-cued trials than on incorrectly-cued trials. Contextual cueing proved to be more robust with photographic backgrounds than with uniformly colored backgrounds. In addition, during the context-target delay, pigeons predominately pecked toward the location of the upcoming target, suggesting that attentional guidance contributes to contextual cueing. These findings confirm the effectiveness of animal models of contextual cueing and underscore the important part played by associative learning in producing the effect.

We examined the role of youth HIV status and other key factors on past-year arrest in perinatally HIV-exposed but uninfected (PHIV-) and perinatally HIV-infected (PHIV+) youth using data from a multi-site study of psychosocial behaviors in PHIV-exposed urban youth (N = 340; 61% PHIV+; 51% female; ages 9-16 at baseline). Youth and caregivers were administered 5 interviews, spanning approximately 7.5 years. Using longitudinal logistic mixed-effect models, we explored the association between past year arrest, internal [e.g., substance use disorder (SUD)] and external (e.g., neighborhood arrest rates) contextual factors, and social-regulation processes (e.g., in-school/work). Arrest rates increased from 2.6 to 19.7% across follow-ups; there were no differences in arrest over time by HIV status. In the final model, odds of arrest were greater for youth who were male, with SUD, ≥ 18 years old, with high levels of city stress, and neither in school nor employed. PHIV-exposed, urban youth have much higher rates of arrest than national samples. Lack of differences in arrest by HIV status suggests key contextual factors are more important in promoting arrest.

Active interoceptive inference and the emotional brain

PubMed Central

Friston, Karl J.

2016-01-01

We review a recent shift in conceptions of interoception and its relationship to hierarchical inference in the brain. The notion of interoceptive inference means that bodily states are regulated by autonomic reflexes that are enslaved by descending predictions from deep generative models of our internal and external milieu. This re-conceptualization illuminates several issues in cognitive and clinical neuroscience with implications for experiences of selfhood and emotion. We first contextualize interoception in terms of active (Bayesian) inference in the brain, highlighting its enactivist (embodied) aspects. We then consider the key role of uncertainty or precision and how this might translate into neuromodulation. We next examine the implications for understanding the functional anatomy of the emotional brain, surveying recent observations on agranular cortex. Finally, we turn to theoretical issues, namely, the role of interoception in shaping a sense of embodied self and feelings. We will draw links between physiological homoeostasis and allostasis, early cybernetic ideas of predictive control and hierarchical generative models in predictive processing. The explanatory scope of interoceptive inference ranges from explanations for autism and depression, through to consciousness. We offer a brief survey of these exciting developments.

Issues related to program context are important components of population health interventions and particularly among complex, adaptive initiatives in schools. Health Promoting Schools (HPS) is a global approach to support early development of healthy behaviors among children and youth. The purpose of this study was to explicate the practical and contextual processes that influenced implementation of HPS in schools in Nova Scotia (Canada). Using a case-study approach, data was collected using interviews (n=14) with principals, teachers and parents, observations collected during school visits and document review in five diverse schools. Case study schools reported a variety of HPS practices and three key themes emerged that provided context to the processes that facilitated their implementation. The results suggest that although school characteristics (theme 1), like staff allocation, physical location and resources, are important, these barriers can be mitigated by building organizational capacity (theme 2) and establishing a supportive school community culture (theme 3). The study provided insight to the variability in implementation by describing how contextual barriers were experienced and mitigated by schools. Establishing a broad system to support HPS, with collaboration across health and education sectors, could help to progress adoption, implementation and sustainability of HPS.

Issue addressed The context of community-based childhood obesity prevention programs can influence the effects of these intervention programs. Leadership readiness for community mobilisation for childhood obesity prevention is one such contextual factor. This study assessed perceived community leadership readiness (PCLR) at two time points in a state-wide, multisite community-based childhood obesity prevention program. Methods PCLR was assessed across 168 suburbs of 20 intervention communities participating in South Australia's Obesity Prevention and Lifestyle (OPAL) program. Using a validated online PCLR tool, four key respondents from each community rated each suburb within their respective community on a nine-point scale for baseline and 2015. Average PCLR and change scores were calculated using the general linear model with suburbs nested in communities. Relationships between demographic variables and change in PCLR were evaluated using multiple regression. Ease of survey use was also assessed. Results Average PCLR increased between baseline (3.51, s.d.=0.82) and 2015 (5.23, s.d.=0.89). PCLR rose in 18 of 20 intervention communities. PCLR was inversely associated with suburb population size (r 2 =0.03, P=0.03, β=-0.25) and positively associated with intervention duration (r 2 change=0.08, P=0.00, β=0.29). Only 8% of survey respondents considered the online assessment tool difficult to use. Conclusions PCLR increased over the course of the OPAL intervention. PCLR varied between and within communities. Online assessment of PCLR has utility for multisite program evaluations. So what? Use of a novel, resource-efficient online tool to measure the key contextual factors of PCLR has enabled a better understanding of the success and generalisability of the OPAL program.

Contextual Compression of Large-Scale Wind Turbine Array Simulations

Data sizes are becoming a critical issue particularly for HPC applications. We have developed a user-driven lossy wavelet-based storage model to facilitate the analysis and visualization of large-scale wind turbine array simulations. The model stores data as heterogeneous blocks of wavelet coefficients, providing high-fidelity access to user-defined data regions believed the most salient, while providing lower-fidelity access to less salient regions on a block-by-block basis. In practice, by retaining the wavelet coefficients as a function of feature saliency, we have seen data reductions in excess of 94 percent, while retaining lossless information in the turbine-wake regions most critical to analysismore » and providing enough (low-fidelity) contextual information in the upper atmosphere to track incoming coherent turbulent structures. Our contextual wavelet compression approach has allowed us to deliver interative visual analysis while providing the user control over where data loss, and thus reduction in accuracy, in the analysis occurs. We argue this reduced but contextualized representation is a valid approach and encourages contextual data management.« less

A critical theory of medical discourse: how patients and health professionals deal with social problems.

PubMed

Waitzkin, H; Britt, T

1989-01-01

Criticism of social context does not generally appear in medical encounters. When contextual issues arise in medical discourse, messages of ideology and social control may become apparent, usually without the conscious awareness of the participants. By easing the physical or psychological impact of contextual difficulties, or by encouraging patients' conformity to mainstream expectations of desirable behavior, encounters with doctors can help win patients' consent to troubling social conditions. Seen in this light, doctor-patient encounters become micropolitical situations that do not typically encourage explicit statements or actions by health professionals to change contextual sources of their patients' difficulties. A critical theory influenced by structuralism suggests that the surface meanings of signs in medical discourse prove less important than their structural relationships. In addition, a theoretical approach adopting elements of post-structuralism and Marxist literary criticism emphasizes the marginal, absent, or excluded elements of medical discourse. Contextual features that shape a text include social class, sex, age, and race. Through the underlying structure of medical discourse, contextual problems are expressed, marginalized, and managed.

Contextuality in canonical systems of random variables

2017-10-01

Random variables representing measurements, broadly understood to include any responses to any inputs, form a system in which each of them is uniquely identified by its content (that which it measures) and its context (the conditions under which it is recorded). Two random variables are jointly distributed if and only if they share a context. In a canonical representation of a system, all random variables are binary, and every content-sharing pair of random variables has a unique maximal coupling (the joint distribution imposed on them so that they coincide with maximal possible probability). The system is contextual if these maximal couplings are incompatible with the joint distributions of the context-sharing random variables. We propose to represent any system of measurements in a canonical form and to consider the system contextual if and only if its canonical representation is contextual. As an illustration, we establish a criterion for contextuality of the canonical system consisting of all dichotomizations of a single pair of content-sharing categorical random variables. This article is part of the themed issue `Second quantum revolution: foundational questions'.

Beyond the checklist: understanding rural health vulnerability in a South African context.

Vulnerability in the past has sometimes been measured and understood in terms of checklists or common understanding. It is argued here that vulnerability is a more complex issue than this. Although checklists of vulnerable groups are important, they do not capture the essence and dynamics of vulnerability. The case of rural health vulnerability in South Africa is discussed to show that classifying people into vulnerable groups does not portray the complexity and intricacies of what it means to have vulnerability. We also wish to show that there are different kinds of vulnerabilities, and the difference between access vulnerability and illness vulnerability is highlighted. As part of a larger study, this case study is presented to show how vulnerability in a poor rural community in South Africa has to be understood in a contextual and dynamic manner as opposed to a static manner. Family and social dynamics can influence health. For example, fractured families were seen as a vulnerable issue within the community, while being a person with a disability can lead to isolation and callous attitudes towards them. It is these family and social dynamics that lead proximally to vulnerability to ill health. A contextual approach can assist in giving a more layered understanding of vulnerability than a checklist approach can do. Interventions to change health cannot be addressed simply by medical means. Social conditions need to be changed, and part of changing social conditions is the process of assisting those who are isolated or experience themselves as vulnerable to reconnect with others in the community. Poverty leads to social exclusion; social and family inclusion may be key to well-being.

Data-sharing is a desired default in the field of public health and a source of much ethical deliberation. Sharing data potentially contributes the largest, most efficient source of scientific data, but is fraught with contextual challenges which make stakeholders, particularly those in under-resourced contexts hesitant or slow to share. Relatively little empirical research has engaged stakeholders in discussing the issue. This study sought to explore relevant experiences, contextual, and subjective explanations around the topic to provide a rich and detailed presentation of what it means to different stakeholders and contexts to share data and how that can guide practice and ethical guidance. A qualitative design involving interviews was undertaken with professionals working in public health institutions endowed with data (HDSS), ethics committees, and advisory agencies which help shape health research in Africa. A descriptive form of thematic analysis was used to summarize results into six key themes: (1) The role of HDSSs in research using public health data and data-sharing; (2) Ownership and funding are critical factors influencing data-sharing; (3) Other factors discourage data-sharing; (4) Promoting and sustaining data-sharing; (5) Ethical guidance structures; and (6) Establishing effective guidance. The themes reveal factors regarding the willingness or not to share and an intricate ethical system that current discourse could reflect. Many of the concerns resonate with the literature, but a whole other gamut of people and process issues; commitments, investments, careers, and the right ethical guidance are needed to realize a sustainable goal of reaching 'share' as a default. © 2017 John Wiley & Sons Ltd.

Estrogen modulates sexually dimorphic contextual fear extinction in rats through estrogen receptor beta.

Females and males are different in brain and behavior. These sex differences occur early during development due to a combination of genetic and hormonal factors and continue throughout the lifespan. Previous studies revealed that male rats exhibited significantly higher levels of contextual fear memory than female rats. However, it remains unknown whether a sex difference exists in the contextual fear extinction. To address this issue, male, normally cycling female, and ovariectomized (OVX) female Sprague-Dawley rats were subjected to contextual fear conditioning and extinction trials. Here we report that although male rats exhibited higher levels of freezing than cycling female rats after contextual fear conditioning, female rats subjected to conditioning in the proestrus and estrus stage exhibited an enhancement of fear extinction than male rats. An estrogen receptor (ER) beta agonist diarylpropionitrile but not an ERalpha agonist propyl-pyrazole-triol administration also enhanced extinction of contextual fear in OVX female rats, suggesting that estrogen-mediated facilitation of extinction involves the activation of ERbeta. Intrahippocampal injection of estradiol or diarylpropionitrile before extinction training in OVX female rats remarkably reduced the levels of freezing response during extinction trials. In addition, the locomotion or anxiety state of female rats does not vary across the ovarian cycle. These results reveal a crucial role for estrogen in mediating sexually dimorphic contextual fear extinction, and that estrogen-mediated enhancement of fear extinction involves the activation of ERbeta.

Achieving the United Nations Sustainable Development Goals in sub-Saharan Africa will require substantial improvements in the coverage and performance of primary health care delivery systems. Projects supported by the Doris Duke Charitable Foundation's (DDCF) African Health Initiative (AHI) created public-private-academic and community partnerships in five African countries to implement and evaluate district-level health system strengthening interventions. In this study, we captured common implementation experiences and lessons learned to understand core elements of successful health systems interventions. We used qualitative data from key informant interviews and annual progress reports from the five Population Health Implementation and Training (PHIT) partnership projects funded through AHI in Ghana, Mozambique, Rwanda, Tanzania, and Zambia. Four major overarching lessons were highlighted. First, variety and inclusiveness of concerned key players (public, academic and private) are necessary to address complex health system issues at all levels. Second, a learning culture that promotes evidence creation and ability to efficiently adapt were key in order to meet changing contextual needs. Third, inclusion of strong implementation science tools and strategies allowed informed and measured learning processes and efficient dissemination of best practices. Fourth, five to seven years was the minimum time frame necessary to effectively implement complex health system strengthening interventions and generate the evidence base needed to advocate for sustainable change for the PHIT partnership projects. The AHI experience has raised remaining, if not overlooked, challenges and potential solutions to address complex health systems strengthening intervention designs and implementation issues, while aiming to measurably accomplish sustainable positive change in dynamic, learning, and varied contexts.

2013-12-01

There has been a dramatic increase in attention to the field of palliative care and end-of-life (PCEOL) research over the past 20 years. This increase is particularly notable in the development of palliative care clinical and educational programs. However, there remain important shortcomings in the evidence base to ensure access to and delivery of effective palliative care for patients with life-limiting illness and their families. Development of this evidence base will require that we train the next generation of researchers to focus on issues in PCEOL. The purpose of this article was to explore the current status of the recruitment, training, and retention of future investigators in PCEOL research in the U.S. and propose recommendations to move us forward. Some key contextual issues for developing and supporting this research workforce are articulated, along with timely and important research areas that will need to be addressed during research training and career development. We provide targeted key recommendations to facilitate the nurturing and support of the future research workforce that is needed to ensure the development and implementation of the science necessary for providing high-quality, evidence-based palliative care to all who need and desire it.

2015-12-01

The proportion of young people in New Zealand identifying with Asian ethnicities has increased considerably. Despite some prevalent health concerns, Asian youth are less likely than non-Asian peers to seek help. As preparatory research towards a more nuanced approach to service delivery and public policy, this qualitative study aimed to identify young Asian New Zealanders' perspectives on best approaches to investigate health issues of priority concern to them. Three semi-structured focus group discussions were conducted with 15 Asian youth leaders aged 18-24 years. Using an inductive approach for thematic analysis, key themes were identified and analysed. Study participants considered ethno-cultural identity, racism and challenges in integration to play significant roles influencing the health of Asian youth (especially mental health) and their access to health services. While emphasising the importance of engaging young Asians in research and service development so that their needs and aspirations are met, participants also highlighted the need for approaches that are cognisant of the cultural, contextual and intergenerational dimensions of issues involved in promoting youth participation. Research that engages Asian youth as key agents using methods that are sensitive to their cultural and sociological contexts can inform more responsive health services and public policy. This is of particular relevance in primary health care where culturally competent services can mitigate risks of unmet health needs and social isolation.

A contextual model of self-regulation change mechanisms among individuals with addictive disorders.

PubMed

Roos, Corey R; Witkiewitz, Katie

2017-11-01

Numerous behavioral treatments for addictive disorders include components explicitly aimed at targeting self-regulation (e.g., coping and emotion regulation). We first provide a summary of key findings to date among studies that have examined self-regulation as a mechanism of behavior change (MOBC) in behavioral treatments for addictive disorders. Based on our review, we conclude that the role of self-regulation as a MOBC across behavioral treatments for addictive disorders is not well-characterized and findings are inconsistent across studies. For example, our review indicates that there is still inconsistent evidence that coping is a unique MOBC in cognitive-behavioral approaches for addictive behaviors. We propose that there has been slow progress in understanding self-regulation as a MOBC in addiction treatment because of a lack of attention to contextual factors. Accordingly, in the second half of this paper, we propose a contextual model of self-regulation change mechanisms, which emphasizes that the role of various facets of self-regulation as MOBC may depend on contextual factors in the immediate situational context (e.g., fluctuating internal and external cues) and in the broader context in which an individual is embedded (e.g., major life stressors, environmental conditions, dispositions). Additionally, we provide specific recommendations to guide future research for understanding both between-person and within-person self-regulation MOBC in addiction treatment. In particular, we provide key recommendations for how to capitalize on intensive longitudinal measurement methods (e.g., ecological momentary assessment) when bringing a contextual perspective to the study of self-regulation as MOBC in various addiction treatments.

What is an affordance? 40 years later.

About 40 years ago, James J. Gibson coined the term "affordance" to describe the action possibilities offered to an animal by the environment with reference to the animal's action capabilities. Since then, this notion has acquired a multitude of meanings, generating confusion in the literature. Here, we offer a clear operationalization of the concept of affordances and related concepts in the field of tool use. Our operationalization is organized around the distinction between the physical (what is objectively observable) and neurocognitive (what is subjectively experienced) levels. This leads us to propose that motor control (dorso-dorsal system), mechanical knowledge (ventro-dorsal system) and function knowledge (ventral system) could be neurocognitive systems respectively involved in the perception of affordances, the understanding of mechanical actions and the storage of contextual relationships (three action-system model; 3AS). We end by turning to two key issues that can be addressed within 3AS. These issues concern the link between affordances and tool incorporation, and the constraints posed by affordances for tool use.

Eph receptors regulate glutamate receptors functions, neuronal morphology and synaptic plasticity, cellular events believed to be involved in memory formation. In this study we aim to explore the roles of Eph receptors in learning and memory. Toward that end, we examined the roles of EphB2 and EphA4 receptors, key regulators of synaptic functions, in fear conditioning memory formation. We show that mice lacking EphB2 (EphB2(-/-)) are impaired in short- and long-term contextual fear conditioning memory. Mice that express a carboxy-terminally truncated form of EphB2 that lacks forward signaling, instead of the full EphB2, are impaired in long-term, but not short-term, contextual fear conditioning memory. Long-term contextual fear conditioning memory is attenuated in CaMKII-cre;EphA4(lx/-) mice where EphA4 is removed from all pyramidal neurons of the forebrain. Mutant mice with targeted kinase-dead EphA4 (EphA4(KD)) exhibit intact long-term contextual fear conditioning memory showing that EphA4 kinase-mediated forward signaling is not needed for contextual fear memory formation. The ability to form long-term conditioned taste aversion (CTA) memory is not impaired in the EphB2(-/-) and CaMKII-cre;EphA4(lx/-) mice. We conclude that EphB2 forward signaling is required for long-term contextual fear conditioning memory formation. In contrast, EphB2 mediates short-term contextual fear conditioning memory formation in a forward signaling-independent manner. EphA4 mediates long-term contextual fear conditioning memory formation in a kinase-independent manner. Copyright © 2015 Elsevier Inc. All rights reserved.

2008-09-01

The development of ICD-11 provides an opportunity to update the description of delirium according to emerging data that have added to our understanding of this complex neuropsychiatric syndrome. Synthetic article based on published work considered by the authors to be relevant to the definition of delirium. The current DSM-IV definition of delirium is preferred to the ICD-10 because of its greater inclusivity. Evidence does not support major changes in the principal components of present definitions but a number of key issues for the updated definition were identified. These include better account of non-cognitive features, more guidance for rating contextual diagnostic items, clearer definition regarding the interface with dementia, and accounting for illness severity, clinical subtypes and course. Development of the ICD definition of delirium can allow for more targeted research and clinical effort.

The requirements engineering (RE) processes have become a key in developing and deploying enterprise information system (EIS) for organisations and corporations in various fields and industrial sectors. Ethnography is a contextual method allowing scientific description of the stakeholders, their needs and their organisational customs. Despite the recognition in the RE literature that ethnography could be helpful, the actual leverage of the method has been limited and ad hoc. To overcome the problems, we report in this paper a systematic mapping study where the relevant literature is examined. Building on the literature review, we further identify key parameters, their variations and their connections. The improved understanding about the role of ethnography in EIS RE is then presented in a consolidated model, and the guidelines of how to apply ethnography are organised by the key factors uncovered. Our study can direct researchers towards thorough understanding about the role that ethnography plays in EIS RE, and more importantly, to help practitioners better integrate contextually rich and ecologically valid methods in their daily practices.

Why Contextual Preference Reversals Maximize Expected Value

PubMed Central

2016-01-01

Contextual preference reversals occur when a preference for one option over another is reversed by the addition of further options. It has been argued that the occurrence of preference reversals in human behavior shows that people violate the axioms of rational choice and that people are not, therefore, expected value maximizers. In contrast, we demonstrate that if a person is only able to make noisy calculations of expected value and noisy observations of the ordinal relations among option features, then the expected value maximizing choice is influenced by the addition of new options and does give rise to apparent preference reversals. We explore the implications of expected value maximizing choice, conditioned on noisy observations, for a range of contextual preference reversal types—including attraction, compromise, similarity, and phantom effects. These preference reversal types have played a key role in the development of models of human choice. We conclude that experiments demonstrating contextual preference reversals are not evidence for irrationality. They are, however, a consequence of expected value maximization given noisy observations. PMID:27337391

Party Identification, Contact, Contexts, and Public Attitudes toward Illegal Immigration

PubMed Central

Gravelle, Timothy B.

2016-01-01

Illegal immigration is a contentious issue on the American policy agenda. To understand the sources of public attitudes toward immigration, social scientists have focused attention on political factors such as party identification; they have also drawn on theories of intergroup contact to argue that contact with immigrants shapes immigration attitudes. Absent direct measures, contextual measures such as respondents’ ethnic milieu or proximity to salient geographic features (such as borders) have been used as proxies of contact. Such a research strategy still leaves the question unanswered – is it contact or context that really matters? Further, which context, and for whom? This article evaluates the effects of party identification, personal contact with undocumented immigrants, and contextual measures (county Hispanic population and proximity to the US–Mexico border) on American attitudes toward illegal immigration. It finds that contextual factors moderate the effects of political party identification on attitudes toward illegal immigration; personal contact has no effect. These findings challenge the assumption that contextual measures act as proxies for interpersonal contact. PMID:27257305

Prenatal/preconceptional and newborn screening programs have been a focus of recent policy debates that have included attention to ethical, legal, and social issues (ELSIs). In parallel, there has been an ongoing discussion about whether and how ELSIs may be addressed in health technology assessment (HTA). We conducted a knowledge synthesis study to explore both guidance and current practice regarding the consideration of ELSIs in HTA for prenatal/preconceptional and newborn screening. As the concluding activity for this project, we held a Canadian workshop to discuss the issues with a diverse group of stakeholders. Based on key workshop themes integrated with our study results, we suggest that population-based genetic screening programs may present particular types of ELSIs and that a public health ethics perspective is potentially highly relevant when considering them. We also suggest that approaches to addressing ELSIs in HTA for prenatal/preconceptional and newborn screening may need to be flexible enough to respond to diversity in HTA organizations, cultural values, stakeholder communities, and contextual factors. Finally, we highlight a need for transparency in the way that HTA producers move from evidence to conclusions and the ways in which screening policy decisions are made. Copyright © 2008 S.

Low-dose systemic scopolamine disrupts context conditioning in rats.

PubMed

Luyten, Laura; Nuyts, Shauni; Beckers, Tom

2017-06-01

Cholinergic neurotransmission plays a key role in learning and memory. Prior research with rats indicated that a low dose of pre-training scopolamine (0.1 mg/kg), a cholinergic receptor antagonist, did not affect cued fear conditioning, but did block renewal when injected before extinguishing a conditioned tone, opening up opportunities to pharmacologically improve exposure therapy for anxiety patients. Before translating these findings to the clinic, it is important to carefully examine how scopolamine affects contextual fear memories. Here, we investigated the effects of scopolamine on encoding of contextual anxiety and its generalization in male Wistar rats. We found a profound disruption of context conditioning, suggesting that, even at a low dose, systemic scopolamine may influence contextual encoding in the hippocampus, particularly when the context is the best predictor for the presence of shocks.

Contextual elements have significant impact on uptake of health care innovations. While existing conceptual frameworks in implementation science suggest contextual elements interact with each other, little research has described how this might look in practice. To bridge this gap, this study identifies the interconnected patterns among contextual elements that influence uptake of an anticoagulation clinic improvement initiative. We completed 51 semi-structured interviews and ethnographic observations across five case study sites involved in an evidence-based practice (EBP) quality improvement initiative. We analyzed data in NVivo 10 using an a priori approach based on the Promoting Action on Research Implementation in Health Services (PARIHS) model and an emergent thematic analysis. Key contextual elements, such as leadership, teamwork, and communication, interacted with each other in contributing to site-level uptake of the EBP, often yielding results that could not be predicted by looking at just one of these elements alone. Sites with context conducive to change in these areas predictably had high uptake, while sites with uniformly weak contextual elements had low uptake. Most sites presented a mixed picture, with contextual elements being strongly supportive of change in some areas and weak or moderate in others. In some cases, we found that sites with strong context in at least one area only needed to have adequate context in other areas to yield high uptake. At other sites, weak context in just one area had the potential to contribute to low uptake, despite countervailing strengths. Even a site with positive views of EBPs could not succeed when context was weak. Interrelationships among different contextual elements can act as barriers to uptake at some sites and as facilitators at others. Accounting for interconnections among elements enables PARIHS to more fully describe the determinants of successful implementation as they operate in real-world settings.

To describe the creation and validation of six simulations concerned with effective listening and interpersonal communication in pediatric rehabilitation. The simulations involved clinicians from various disciplines, were based on clinical scenarios related to client issues, and reflected core aspects of listening/communication. Each simulation had a key learning objective, thus focusing clinicians on specific listening skills. The article outlines the process used to turn written scenarios into digital video simulations, including steps taken to establish content validity and authenticity, and to establish a series of videos based on the complexity of their learning objectives, given contextual factors and associated macrocognitive processes that influence the ability to listen. A complexity rating scale was developed and used to establish a gradient of easy/simple, intermediate, and hard/complex simulations. The development process exemplifies an evidence-based, integrated knowledge translation approach to the teaching and learning of listening and communication skills.

Surgical swab counting: a qualitative analysis from the perspective of the scrub nurse.

2014-05-01

The aim of the study was to conduct a qualitative exploration of the sociotechnical processes underlying retained surgical swabs, and to explore the fundamental reasons why the swab count procedure and related protocols fail in practice. Data was collected through a set of 27 semistructured qualitative interviews with scrub nurses from a large, multi-site teaching hospital. Interview transcripts were analysed using established constant comparative methods, moving between inductive and deductive reasoning. Key findings were associated with interprofessional perspectives, team processes and climate and responsibility for the swab count. The analysis of risk factors revealed that perceived social and interprofessional issues played a significant role in the reliability of measures to prevent retained swabs. This work highlights the human, psychological and organisational factors that impact upon the reliability of the process and gives rise to recommendations to address contextual factors and improve perioperative practice and training.

On 8 November 2016 the American electorate voted Donald Trump into the Presidency and a majority of Republicans into both houses of Congress. Since many Republicans ran for elected office on the promise to 'repeal and replace' Obamacare, this election result came with an expectation that campaign rhetoric would result in legislative action on healthcare. The American Health Care Act (AHCA) represented the Republican effort to repeal and replace the Affordable Care Act (ACA). Key elements of the AHCA included modifications of Medicaid expansion, repeal of the individual mandate, replacement of ACA subsidies with tax credits, and a broadening of the opportunity to use healthcare savings accounts. Details of the bill and the political issues which ultimately impeded its passage are discussed here. Published by the BMJ Publishing Group Limited.

Social and Contextual Constraints on Embodied Perception.

PubMed

Schnall, Simone

2017-03-01

A number of papers have challenged research on physiological and psychological influences on perception by claiming to show that such findings can be explained by nonperceptual factors such as demand characteristics. Relatedly, calls for separating perception from judgment have been issued. However, such efforts fail to consider key processes known to shape judgment processes: people's inability to report accurately on their judgments, conversational dynamics of experimental research contexts, and misattribution and discounting processes. Indeed, the fact that initially observed effects of embodied influences disappear is predicted by an extensive amount of literature on judgments studied within social psychology. Thus, findings from such studies suggest that the initially presumed underlying processes are at work-namely, functional considerations that are informative in the context of preparing the body for action. In this article, I provide suggestions on how to conduct research on perception within the social constraints of experimental contexts.

A Key Role for Nectin-1 in the Ventral Hippocampus in Contextual Fear Memory

PubMed Central

Grosse, Jocelyn; Krummenacher, Claude; Sandi, Carmen

2013-01-01

Nectins are cell adhesion molecules that are widely expressed in the brain. Nectin expression shows a dynamic spatiotemporal regulation, playing a role in neural migratory processes during development. Nectin-1 and nectin-3 and their heterophilic trans-interactions are important for the proper formation of synapses. In the hippocampus, nectin-1 and nectin-3 localize at puncta adherentia junctions and may play a role in synaptic plasticity, a mechanism essential for memory and learning. We evaluated the potential involvement of nectin-1 and nectin-3 in memory consolidation using an emotional learning paradigm. Rats trained for contextual fear conditioning showed transient nectin-1—but not nectin-3—protein upregulation in synapse-enriched hippocampal fractions at about 2 h posttraining. The upregulation of nectin-1 was found exclusively in the ventral hippocampus and was apparent in the synaptoneurosomal fraction. This upregulation was induced by contextual fear conditioning but not by exposure to context or shock alone. When an antibody against nectin-1, R165, was infused in the ventral-hippocampus immediately after training, contextual fear memory was impaired. However, treatment with the antibody in the dorsal hippocampus had no effect in contextual fear memory formation. Similarly, treatment with the antibody in the ventral hippocampus did not interfere with acoustic memory formation. Further control experiments indicated that the effects of ventral hippocampal infusion of the nectin-1 antibody in contextual fear memory cannot be ascribed to memory non-specific effects such as changes in anxiety-like behavior or locomotor behavior. Therefore, we conclude that nectin-1 recruitment to the perisynaptic environment in the ventral hippocampus plays an important role in the formation of contextual fear memories. Our results suggest that these mechanisms could be involved in the connection of emotional and contextual information processed in the amygdala and dorsal hippocampus, respectively, thus opening new venues for the development of treatments to psychopathological alterations linked to impaired contextualization of emotions.

Confronting the realities of implementing contextual learning ideas in a biology classroom

NASA Astrophysics Data System (ADS)

Akers, Julia B.

1999-10-01

The purpose of this study was to describe the implementation of contextual learning practices in a biology class. Research contends that contextual learning classrooms are active learning environments where students are involved in "hands-on" team projects and the teacher assumes a facilitator role. In this student-centered classroom, students take ownership and responsibility for their own learning. This study examined these assertions and other factors that emerged as the study developed. The research methods used were qualitative. The subject for this study was a biology teacher with twenty-six years of experience who implemented contextual learning practices in two of her biology classes in the 1997--98 school year. As the teacher confronted contextual learning, we engaged in collaborative research that included fourteen interviews transcribed verbatim for analysis, classroom observations and the teacher's written reports. Throughout the study, factors developed that adversely affected contextual learning practices. These factors were discipline, curriculum, and administrative decisions over which the teacher had no control. These are examined along with their consequences for implementing a contextual classroom. Successful practices that worked in the teacher's classroom were also determined and included the teacher's "failure is not an option" policy, mandatory tutoring, behavior contracts, high expectations and teamed projects. Besides contextual learning, a key component of the study was the collaborative research process and its meaning to the subject, the researcher and future researchers who attempt this collaborative approach. The study's conclusion indicate that scheduling, multiple repeaters, discipline and the state Standards of Learning moved the teacher away from contextual learning practices to a more teacher-directed classroom. Two recommendations of this study are that further research is needed to study how the state Standards of Learning have affected instructional practices and the effect of administrative decisions that influence the level of teacher success in the classroom.

Nurses' discourse in contraceptive prescribing: an analysis using Foucault's 'procedures of exclusion'.

PubMed

Hayter, Mark

2007-05-01

This paper is a report of an analysis of the discourse about contraceptive efficacy and side effects used by nurses when prescribing contraception. All women seeking contraception should be informed of the efficacy and potential adverse effects of the particular method they are considering. This information facilitates an informed choice. Women also require this information in order to monitor for any side effects. Paradoxically, side effects are also a key factor in reducing adherence with contraceptive regimens. However, there is no literature that explores specifically how this issue is addressed in clinical consultations, or places these practices in a theoretical context. Forty-nine consultations between nurses and women in sexual health clinics were audio-recorded during 2002. Data were subject to a discourse analysis using Foucault's 'procedures of exclusion' to explore the discursive construction of contraceptive efficacy and side effects The nurses employed specific discursive strategies when discussing contraception. When addressing efficacy, discourse centred on medico-statistical facts, but side effects were described in lay terms that minimized their severity. Nurses contextualized contraceptive side effects within potential problems that women might experience in pregnancy, and also attempted to 'normalize' contraceptive-related problems. Discourse and its deployment play a key role in practitioner-client relationships that sexual health nurses need to become more aware of how they discuss clinical issues about contraception with women. Clinical data on contraceptive side-effects are present in the literature, and it is important that sexual health nurses use this to help women make truly informed decisions.

2007-01-01

Fear memories elicit multiple behavioral responses, encompassing avoidance, or behavioral inhibition in response to threatening contexts. Context-specific freezing, reflecting fear-induced behavioral inhibition, has been proposed as one of the main risks factors for the development of anxiety disorders. We attempted to define the key hippocampal mediators of extinction in a mouse model of context-dependent freezing. Nine-week-old male C57BL/6J mice were trained and tested for contextual fear conditioning and extinction. Freezing behavior scored by unbiased sampling, was used as an index of fear. Proteomic, immunoblot, and immunohistochemical approaches were employed to identify, verify, and analyze the alterations of the hippocampal extracellular signal-regulated kinases 1 and 2 (Erk-1/2). Targeted pharmacological inhibition of the Erk-1/2 activating kinase, the mitogen activated and extracellular signal-regulated kinase (Mek), served to establish the role of Mek/Erk signaling in extinction. When compared to acquisition, extinction of contextual freezing triggered a rapid activation of Erk-1/2 showing a distinctive time-course, nuclear localization, and subcellular isoform distribution. These differences suggested that the upstream regulation and downstream effects of this pathway might be specific for each process. Dorsohippocampal injections of the Mek inhibitors U0126 (0.5 microg/site) and PD98059 (1.5 microg/site) immediately after the nonreinforced trials prevented Erk-1/2 activation and significantly impaired extinction. This effect was dissociable from potential actions on memory retrieval or reconsolidation. On the basis of these findings, we propose that hippocampal Mek/Erk signaling might serve as one of the key mediators of contextual fear extinction.

The KAPTUR environment: An operations concept

NASA Technical Reports Server (NTRS)

1989-01-01

This report presents a high-level specification and operations concept for KAPTUR, a development environment based on knowledge acquisition for preservation of tradeoffs and underlying rationales. KAPTUR is intended to do what its name implies: to capture knowledge that is required or generated during the development process, but that is often lost because it is contextual, i.e., it does not appear directly in the end-products of development. Such knowledge includes issues that were raised during development, alternatives that were considered, and the reasons for choosing one alternative over others. Contextual information is usually only maintained as a memory in a developer's mind. As time passes, the memories become more vague and individuals become unavailable, and eventually the knowledge is lost. KAPTUR seeks to mitigate this process of attrition by recording and organizing contextual knowledge as it is generated.

Influences of motor contexts on the semantic processing of action-related language.

The contribution of the sensory-motor system to the semantic processing of language stimuli is still controversial. To address the issue, the present article focuses on the impact of motor contexts (i.e., comprehenders' motor behaviors, motor-training experiences, and motor expertise) on the semantic processing of action-related language and reviews the relevant behavioral and neuroimaging findings. The existing evidence shows that although motor contexts can influence the semantic processing of action-related concepts, the mechanism of the contextual influences is still far from clear. Future investigations will be needed to clarify (1) whether motor contexts only modulate activity in motor regions, (2) whether the contextual influences are specific to the semantic features of language stimuli, and (3) what factors can determine the facilitatory or inhibitory contextual influences on the semantic processing of action-related language.

Social ecological and developmental system perspectives suggest that interactions among factors within and across multiple contexts (e.g., neighborhood, peer, family) must be considered in explaining dating violence perpetration. Yet, to date, most extant research on dating violence has focused on individual, rather than contextual predictors, and used variable-centered approaches that fail to capture the configurations of factors that may jointly explain involvement in dating violence. The current study used a person-centered approach, latent profile analysis, to identify key configurations (or profiles) of contextual risk and protective factors for dating violence perpetration across the neighborhood, school, friend and family contexts. We then examine the longitudinal associations between these contextual risk profiles, assessed during middle school, and trajectories of psychological and physical dating violence perpetration across grades 8 through 12. Five contextual risk profiles were identified: school, neighborhood, and family risk; school and family risk; school and friend risk; school and neighborhood risk; and low risk. The highest levels of psychological and physical perpetration across grades 8 through 12 were among adolescents in the profile characterized by high levels of school, neighborhood, and family risk. Results suggest that early interventions to reduce violence exposure and increase social regulation across multiple social contexts may be effective in reducing dating violence perpetration across adolescence.

The influence of contextual reward statistics on risk preference

Decision theories mandate that organisms should adjust their behaviour in the light of the contextual reward statistics. We tested this notion using a gambling choice task involving distinct contexts with different reward distributions. The best fitting model of subjects' behaviour indicated that the subjective values of options depended on several factors, including a baseline gambling propensity, a gambling preference dependent on reward amount, and a contextual reward adaptation factor. Combining this behavioural model with simultaneous functional magnetic resonance imaging we probed neural responses in three key regions linked to reward and value, namely ventral tegmental area/substantia nigra (VTA/SN), ventromedial prefrontal cortex (vmPFC) and ventral striatum (VST). We show that activity in the VTA/SN reflected contextual reward statistics to the extent that context affected behaviour, activity in the vmPFC represented a value difference between chosen and unchosen options while VST responses reflected a non-linear mapping between the actual objective rewards and their subjective value. The findings highlight a multifaceted basis for choice behaviour with distinct mappings between components of this behaviour and value sensitive brain regions. PMID:26707890

Classical Causal Models for Bell and Kochen-Specker Inequality Violations Require Fine-Tuning

Cavalcanti, Eric G.

2018-04-01

Nonlocality and contextuality are at the root of conceptual puzzles in quantum mechanics, and they are key resources for quantum advantage in information-processing tasks. Bell nonlocality is best understood as the incompatibility between quantum correlations and the classical theory of causality, applied to relativistic causal structure. Contextuality, on the other hand, is on a more controversial foundation. In this work, I provide a common conceptual ground between nonlocality and contextuality as violations of classical causality. First, I show that Bell inequalities can be derived solely from the assumptions of no signaling and no fine-tuning of the causal model. This removes two extra assumptions from a recent result from Wood and Spekkens and, remarkably, does not require any assumption related to independence of measurement settings—unlike all other derivations of Bell inequalities. I then introduce a formalism to represent contextuality scenarios within causal models and show that all classical causal models for violations of a Kochen-Specker inequality require fine-tuning. Thus, the quantum violation of classical causality goes beyond the case of spacelike-separated systems and already manifests in scenarios involving single systems.

Understanding the context of a health programme is important in interpreting evaluation findings and in considering the external validity for other settings. Public health researchers can be imprecise and inconsistent in their usage of the word "context" and its application to their work. This paper presents an approach to defining context, to capturing relevant contextual information and to using such information to help interpret findings from the perspective of a research group evaluating the effect of diverse innovations on coverage of evidence-based, life-saving interventions for maternal and newborn health in Ethiopia, Nigeria, and India. We define "context" as the background environment or setting of any program, and "contextual factors" as those elements of context that could affect implementation of a programme. Through a structured, consultative process, contextual factors were identified while trying to strike a balance between comprehensiveness and feasibility. Thematic areas included demographics and socio-economics, epidemiological profile, health systems and service uptake, infrastructure, education, environment, politics, policy and governance. We outline an approach for capturing and using contextual factors while maximizing use of existing data. Methods include desk reviews, secondary data extraction and key informant interviews. Outputs include databases of contextual factors and summaries of existing maternal and newborn health policies and their implementation. Use of contextual data will be qualitative in nature and may assist in interpreting findings in both quantitative and qualitative aspects of programme evaluation. Applying this approach was more resource intensive than expected, in part because routinely available information was not consistently available across settings and more primary data collection was required than anticipated. Data was used only minimally, partly due to a lack of evaluation results that needed further explanation, but also because contextual data was not available for the precise units of analysis or time periods of interest. We would advise others to consider integrating contextual factors within other data collection activities, and to conduct regular reviews of maternal and newborn health policies. This approach and the learnings from its application could help inform the development of guidelines for the collection and use of contextual factors in public health evaluation.

A novel framework to alleviate the sparsity problem in context-aware recommender systems

2017-04-01

Recommender systems have become indispensable for services in the era of big data. To improve accuracy and satisfaction, context-aware recommender systems (CARSs) attempt to incorporate contextual information into recommendations. Typically, valid and influential contexts are determined in advance by domain experts or feature selection approaches. Most studies have focused on utilizing the unitary context due to the differences between various contexts. Meanwhile, multi-dimensional contexts will aggravate the sparsity problem, which means that the user preference matrix would become extremely sparse. Consequently, there are not enough or even no preferences in most multi-dimensional conditions. In this paper, we propose a novel framework to alleviate the sparsity issue for CARSs, especially when multi-dimensional contextual variables are adopted. Motivated by the intuition that the overall preferences tend to show similarities among specific groups of users and conditions, we first explore to construct one contextual profile for each contextual condition. In order to further identify those user and context subgroups automatically and simultaneously, we apply a co-clustering algorithm. Furthermore, we expand user preferences in a given contextual condition with the identified user and context clusters. Finally, we perform recommendations based on expanded preferences. Extensive experiments demonstrate the effectiveness of the proposed framework.

The use of a dyadic lens to assess and leverage academic and community partners’ readiness to conduct community-based participatory research (CBPR) has not been systematically investigated. With a lack of readiness to conduct CBPR, the partnership and its products are vulnerable. The purpose of this qualitative study was to explore the dimensions and key indicators necessary for academic and community partnership readiness to conduct CBPR. Key informant interviews and focus groups (n = 36 participants) were conducted with academic and community participants who had experiences with CBPR partnerships. A ‘framework analysis' approach was used to analyze the data and generate a new model, CBPR Partnership Readiness Model. Antecedents of CBPR partnership readiness are a catalyst and mutual interest. The major dimensions of the CBPR Partnership Readiness Model are (i) goodness of fit, (ii) capacity, and (iii) operations. Preferred outcomes are sustainable partnership and product, mutual growth, policy and social and health impact on the community. CBPR partnership readiness is an iterative and dynamic process, partnership and issue specific, influenced by a range of environmental and contextual factors, amenable to change and essential for sustainability and promotion of health and social change in the community.

Contextuality supplies the 'magic' for quantum computation.

2014-06-19

Quantum computers promise dramatic advantages over their classical counterparts, but the source of the power in quantum computing has remained elusive. Here we prove a remarkable equivalence between the onset of contextuality and the possibility of universal quantum computation via 'magic state' distillation, which is the leading model for experimentally realizing a fault-tolerant quantum computer. This is a conceptually satisfying link, because contextuality, which precludes a simple 'hidden variable' model of quantum mechanics, provides one of the fundamental characterizations of uniquely quantum phenomena. Furthermore, this connection suggests a unifying paradigm for the resources of quantum information: the non-locality of quantum theory is a particular kind of contextuality, and non-locality is already known to be a critical resource for achieving advantages with quantum communication. In addition to clarifying these fundamental issues, this work advances the resource framework for quantum computation, which has a number of practical applications, such as characterizing the efficiency and trade-offs between distinct theoretical and experimental schemes for achieving robust quantum computation, and putting bounds on the overhead cost for the classical simulation of quantum algorithms.

Contextual Compression of Large-Scale Wind Turbine Array Simulations: Preprint

Gruchalla, Kenny M; Brunhart-Lupo, Nicholas J; Potter, Kristin C

Data sizes are becoming a critical issue particularly for HPC applications. We have developed a user-driven lossy wavelet-based storage model to facilitate the analysis and visualization of large-scale wind turbine array simulations. The model stores data as heterogeneous blocks of wavelet coefficients, providing high-fidelity access to user-defined data regions believed the most salient, while providing lower-fidelity access to less salient regions on a block-by-block basis. In practice, by retaining the wavelet coefficients as a function of feature saliency, we have seen data reductions in excess of 94 percent, while retaining lossless information in the turbine-wake regions most critical to analysismore » and providing enough (low-fidelity) contextual information in the upper atmosphere to track incoming coherent turbulent structures. Our contextual wavelet compression approach has allowed us to deliver interactive visual analysis while providing the user control over where data loss, and thus reduction in accuracy, in the analysis occurs. We argue this reduced but contexualized representation is a valid approach and encourages contextual data management.« less

Beliefs about the causes of events have implications for emotional reactions, distress, expectations for the future, and behavioral responses. In this article we report on two issues: the organizational context that contributes to nursing aide (NA) assault and reporting, and serendipitous findings that arose from investigating unexpected response rates to a survey. Data were collected in 11 rural nursing homes using a structured prospective event-reporting diary to collect detailed information about incidents of physical aggression, followed by focus groups to further explore NAs' perceptions of these events. Here we report on analysis of 19 focus groups conducted with 138 NAs. Participants described organizational-level factors that constrained their practice, affected their interactions with residents, and created a context that put them at risk for physical assault. These factors also affected their willingness to provide written documentation about aggressive incidents. The key issues were frustration at being blamed for causing aggression, lack of action to address the problem, and a desire for respect and involvement in decision making. Organizational changes are needed to modify the contextual factors contributing to assault risk. Researchers must be willing to modify study designs to more fully understand the nature of the problem studied.

Using PROMs to guide patients and practitioners through the head and neck cancer journey

Rogers, Simon N; Barber, Brittany

2017-01-01

The measurement of patient-reported outcome measures (PROMs) following head and neck cancer (HNC) has the capacity to substantially enhance the care of patients and their care-givers following the diagnosis and treatment of HNC. Literature concerning PROMs has increased exponentially in the past 2 decades, producing a vast array of data upon which the multidisciplinary team can reflect. For this review, “Handle On QOL” has been used as a source of references to illustrate the points raised. PROMs are contextualized by considering the clinically-distinct key stages that cancer patients endure: diagnosis, treatment, acute toxicity, early recovery, late effects, recurrence, and palliation. The PROMs are considered in six main categories: 1) those addressing cornucopia of issues not specific to cancer; 2) those addressing issues common to all cancers; 3) questionnaires with items specific to HNC; 4) questionnaires that focus on a particular aspect of head and neck function; 5) those measuring psychological concerns, such as depression, anxiety, or self-esteem; and 6) item prompt lists. Potential benefits of PROMs in clinical practice are discussed, as are barriers to use. The way forward in integrating PROMs into routine HNC care is discussed with an emphasis on information technology. PMID:29184455

Interferometric side scan sonar and data fusion

This paper concerns the possibilities of sea bottom imaging and altitude determining of each imaged point. The performances of new side scan sonars which are able to image the sea bottom with a high definition and are able to evaluate the relief with the same definition derive from an interferometric multisensor system. The drawbacks concern the precision of the numerical altitude model. One way to improve the measurements precision is to merge all the information issued from the multi-sensors system. This leads to increase the Signal to Noise Ratio (SNR) and the robustness of the used method. The aim of this paper is to clearly demonstrate the ability to derive benefits of all information issued from the three arrays side scan sonar by merging: (1) the three phase signals obtained at the output of the sensors, (2) this same set of data after the application of different processing methods, and (3) the a priori relief contextual information. The key idea the proposed fusion technique is to exploit the strength and the weaknesses of each data element in the fusion of process so that the global SNR will be improved as well as the robustness to hostile noisy environments.

Evidence of a transnational arts and health practice methodology? A contextual framing for comparative community-based participatory arts practice in the UK and Mexico

2014-01-01

Background This paper draws on new research exploring community-based, participatory arts practice in Northern England and Mexico City to discuss contextual influences on artists’ practice, and whether a common practice model can be identified. The international comparison is used to interrogate whether such a practice model is transnational, displaying shared characteristics that transcend contextual differences. Methods The study used multi-site ethnography to investigate the participatory practice of more than 40 artists. Participant observation and extended individual and group dialogues provided data on practice in a diverse range of art forms and settings, analysed using open coding and grounded theory principles. Results Findings locate differences in practitioners’ motivations, and perceptions of the work’s function; however, key similarities emerge across both sites, in practitioners’ workshop methodologies and crucially in their creative strategies for catalysing change. A model is presented distilling the key elements of a common practice methodology, found across the study and across art forms. Conclusions The discussion notes where divergences echo nationalities of contributors, drawing inferences about the level of influence of national context in this work, and concludes with the implications of these findings for potential international collaboration, to face challenges within the community arts and health sector globally.

Current studies have produced a plethora of remote health monitoring (RHM) systems designed to enhance the care of patients with chronic diseases. Many RHM systems are designed to improve patient risk factors for cardiovascular disease, including physiological parameters such as body mass index (BMI) and waist circumference, and lipid profiles such as low density lipoprotein (LDL) and high density lipoprotein (HDL). There are several patient characteristics that could be determining factors for a patient's RHM outcome success, but these characteristics have been largely unidentified. In this paper, we analyze results from an RHM system deployed in a six month Women's Heart Health study of 90 patients, and apply advanced feature selection and machine learning algorithms to identify patients' key baseline contextual features and build effective prediction models that help determine RHM outcome success. We introduce Wanda-CVD, a smartphone-based RHM system designed to help participants with cardiovascular disease risk factors by motivating participants through wireless coaching using feedback and prompts as social support. We analyze key contextual features that secure positive patient outcomes in both physiological parameters and lipid profiles. Results from the Women's Heart Health study show that health threat of heart disease, quality of life, family history, stress factors, social support, and anxiety at baseline all help predict patient RHM outcome success.

[Methodological deficits in neuroethics: do we need theoretical neuroethics?].

PubMed

Northoff, G

2013-10-01

Current neuroethics can be characterized best as empirical neuroethics: it is strongly empirically oriented in that it not only includes empirical findings from neuroscience but also searches for applications within neuroscience. This, however, neglects the social and political contexts which could be subject to a future social neuroethics. In addition, methodological issues need to be considered as in theoretical neuroethics. The focus in this article is on two such methodological issues: (1) the analysis of the different levels and their inferences among each other which is exemplified by the inference of consciousness from the otherwise purely neuronal data in patients with vegetative state and (2) the problem of linking descriptive and normative concepts in a non-reductive and non-inferential way for which I suggest the mutual contextualization between both concepts. This results in a methodological strategy that can be described as contextual fact-norm iterativity.

Qualitative methods have long been a part of health education research, but how qualitative approaches advance health equity has not been well described. Qualitative research is an increasingly important methodologic tool to use in efforts to understand, inform, and advance health equity. Qualitative research provides critical insight into the subjective meaning and context of health that can be essential for understanding where and how to intervene to inform health equity research and practice. We describe the larger context for this special theme issue of Health Education & Behavior, provide brief overviews of the 15 articles that comprise the issue, and discuss the promise of qualitative research that seeks to contextualize and illuminate answers to research questions in efforts to promote health equity. We highlight the critical role that qualitative research can play in considering and incorporating a diverse array of contextual information that is difficult to capture in quantitative research.

2010-11-01

The present study analyzes decision-making and argumentation by high school students in a debate situation on a socioscientific issue, the use of embryonic stem cells in research and therapy. We tested the influence on the debates of two different contexts. Adolescent students at the high school level in the same grade (mean age 16.4 years) from rural and urban zones of Provence, France, participated in three debate sessions. During the first session, the students listed the background questions they wanted to ask the expert(s). They were also required to identify one or two major issues that would serve as an outline for the future debate. They then discussed these with the expert(s) during the second session and took note of the answers. During this session, the control groups met with a neuroscientist whereas the experimental 'contextualized' group met with the same neuroscientist together with a representative of an association of patients suffering from a neurodegenerative disease. Analysis of the students' arguments and decision-making revealed that contextualization introduced dynamism in the students' exchanges: they paid more attention to their peers' arguments and were more motivated to argue their own opinion. However, this type of contextualization may contribute to reinforcing ideology in scientific progress.

2017-01-01

Online social networks (OSN) enable health professionals to learn informally, for example by sharing medical knowledge, or discussing practice management challenges and clinical issues. Understanding the learning context in OSN is necessary to get a complete picture of the learning process, in order to better support this type of learning. This study proposes critical contextual factors for understanding the learning context in OSN for health professionals, and demonstrates how these contextual factors can be used to analyse the learning context in a designated online learning environment for health professionals.

The colliding epidemics of non-communicable diseases including diabetes with chronic infectious diseases in Sub-Saharan Africa requires contextualized innovative disease management strategies. This qualitative study conducted in a peri-urban township near Cape Town, South Africa aimed to identify and gain in-depth understanding of contextual and environmental issues pertinent to the patient that could influence Type 2-diabetes mellitus (T2DM) care and self-management. Participants included purposively sampled diabetics or pre-diabetics from the community, PURE study database, facility health club and health care providers. Data collection employed in-depth interviews, focus group discussions (FGDs) using structured interviews and FGD topic guides. Thematic data analysis was done to identify recurrent themes. Themes identified: knowledge and awareness about T2DM; health-seeking behaviour; weight perceptions; healthy lifestyles; self-management; health education needs and health care provider experiences. Patients defined T2DM as a physically and emotionally dangerous disease caused by socio-cultural factors, influenced by the sufferers' food and socio-cultural environment with significance placed on physical, social and emotional effects of T2DM diagnosis. Patient-centred definition of T2DM is key to enhancing T2DM self-management. Patients suggested that personally rewarding benefits of physical activity and healthy diet such as anti-ageing, brain boosting, energy boosting which are commonly harnessed by food, tobacco and beauty industry should be considered in T2DM self-management strategies.

The behavioral theory constructs most often used to study mammography utilization—perceived benefit, perceived susceptibility, self-efficacy, intention, and subjective norms—have neither been developed nor sufficiently tested among diverse racial/ethnic subgroups. The authors explored these constructs and their underlying assumptions relating to the social context of Filipina and Latina women. The mixed-methods study included testing construct measures in the multilingual surveys of a concurrent intervention study of 1,463 women from five ethnic groups. An intensive inductive investigation then targeted Latina and Filipina women to elucidate connections between social context and individual screening behavior. In-depth interviews were conducted with 11 key informant scholars, 13 community gatekeepers, and 29 lay women, and a supplemental study videotaped and interviewed 9 mother–daughter dyads. Three social context domains emerged: relational culture, social capital, and transculturation and transmigration. The meaning and appropriateness of the five behavioral constructs were analyzed in relation to these domains. In contradistinction to tenets of behavioral theory, the authors found that social context can influence behavior directly, circumventing or attenuating the influence of individual beliefs; contextual influences, synthesized from multiple perspectives, can operate at an unconscious level not accessible to the individual; and contextual influences are dynamic, contingent on distal and proximal forces coming together in a given moment and are thus not consistent with an exclusive focus at the individual level. This article describes the study methods, summarizes main findings, and previews the detailed results presented in the other articles in this issue. PMID:19805789

Practising alchemy: the transmutation of evidence into best health care.

PubMed

Goodyear-Smith, Felicity

2011-04-01

Alchemy was the synthesis or transmutation of all elements in perfect balance to obtain the philosopher's stone, the key to health. Just as alchemists sought this, so health practitioners always seek the best possible practice for optimal health outcomes for our patients. Best practice requires full knowledge--a little information can be dangerous. We need to serve our apprenticeship before we master our profession. Our profession is about improving health care. While the journey may start at medical school, the learning never ceases. It is not only about practising medicine, it is about the development of the practitioner. Professional practice requires systematic thinking combined with capacity to deal morally and creatively in areas of complexity and uncertainty appropriate to a specific context. It requires exemplary communication skills to interact with patients to facilitate collaborative decision making resulting in best practice. The synthesis of scientific and contextual evidence is a concept which applies to all disciplines where theoretical knowledge needs to be transferred to action to inform best practice. Decisions need to be made which take into account a complex array of factors, such as social and legal issues and resource constraints. Therefore, journey towards best practice involves transmutation of these three elements: scientific knowledge, the context in which it is applied and phronesis, the practical wisdom of the practitioner. All science has its limitations and we can never know all possible contextual information. Hence, like the philosopher's stone, best practice is a goal to which we aspire but never quite attain.

Towards explaining the health impacts of residential energy efficiency interventions - A realist review. Part 1: Pathways.

Willand, Nicola; Ridley, Ian; Maller, Cecily

2015-05-01

This paper is Part 1 of a realist review that tries to explain the impacts of residential energy efficiency interventions (REEIs) on householder health. According to recent systematic reviews residential energy efficiency interventions may benefit health. It is argued that home energy improvement are complex interventions and that a better understanding of the latent mechanisms and contextual issues that may shape the outcome of interventions is needed for effective intervention design. This realist review synthesises the results of 28 energy efficiency improvement programmes. This first part provides a review of the explanatory factors of the three key pathways, namely warmth in the home, affordability of fuel and psycho-social factors, and the pitfall of inadequate indoor air quality. The review revealed that REEIs improved winter warmth and lowered relative humidity with benefits for cardiovascular and respiratory health. In addition, residential energy efficiency improvements consolidated the meaning of the home as a safe haven, strengthened the householder's perceived autonomy and enhanced social status. Although satisfaction with the home proved to be an important explanation for positive mental health outcomes, financial considerations seemed to have played a secondary role. Evidence for negative impacts was rare but the risk should not be dismissed. Comprehensive refurbishments were not necessarily more effective than thermal retrofits or upgrades. A common protocol for the quantitative and qualitative evaluation of interventions would facilitate the synthesis of future studies. Householder and contextual influences are addressed in Part 2.

(Implicitly) judging a book by its cover: the power of pride and shame expressions in shaping judgments of social status.

PubMed

Shariff, Azim F; Tracy, Jessica L; Markusoff, Jeffrey L

2012-09-01

How do we decide who merits social status? According to functionalist theories of emotion, the nonverbal expressions of pride and shame play a key role, functioning as automatically perceived status signals. In this view, observers automatically make status inferences about expressers on the basis of these expressions, even when contradictory contextual information about the expressers' status is available. In four studies, the authors tested whether implicit and explicit status perceptions are influenced by pride and shame expressions even when these expressions' status-related messages are contradicted by contextual information. Results indicate that emotion expressions powerfully influence implicit and explicit status inferences, at times neutralizing or even overriding situational knowledge. These findings demonstrate the irrepressible communicative power of emotion displays and indicate that status judgments can be informed as much (and often more) by automatic responses to nonverbal expressions of emotion as by rational, contextually bound knowledge.

Neighborhood Age Structure and its Implications for Health

PubMed Central

2006-01-01

Age structure at the neighborhood level is rarely considered in contextual studies of health. However, age structure can play a critical role in shaping community life, the availability of resources, and the opportunities for social engagement—all factors that, research suggests, have direct and indirect effects on health. Age structure can be theorized as a compositional effect and as a contextual effect. In addition, the dynamic nature of age structure and the utility of a life course perspective as applied to neighborhood effects research merits attention. Four Chicago neighborhoods are summarized to illustrate how age structure varies across small space, suggesting that neighborhood age structure should be considered a key structural covariate in contextual research on health. Considering age structure implies incorporating not only meaningful cut points for important age groups (e.g., proportion 65 years and over) but attention to the shape of the distribution as well.

2013-01-01

Historically, much of the research on parenting has not disentangled the influences of race/ethnicity, SES, and culture on family functioning and the development of children and adolescents. This special issue addresses this gap by disentangling ethnic differences in parenting behaviors from their contextual influences, thereby deepening understanding of parenting processes in diverse families. Six members of the Parenting section of the Study Group on Race, Culture and Ethnicity (SGRCE) introduce and implement a novel approach toward understanding this question. The goal of this project is to study culturally related processes and the degree to which they predict parenting. An iterative process was employed to delineate the main parenting constructs (warmth, psychological and behavioral control, monitoring, communication, and self-efficacy), cultural processes, and contextual influences, and to coordinate a data analytic plan utilizing individual datasets with diverse samples to answer the research questions.

Trait anxiety, a stable personality trait associated with increased fear responses to threat, is regarded as a risk factor for the development and maintenance of anxiety disorders. Although the effect of trait anxiety has been examined with regard to explicit threat cues, little is known about the effect of trait anxiety on contextual threat learning. To assess this issue, extreme groups of low and high trait anxiety underwent a contextual fear conditioning protocol using virtual reality. Two virtual office rooms served as the conditioned contexts. One virtual office room (CXT+) was paired with unpredictable electrical stimuli. In the other virtual office room, no electrical stimuli were delivered (CXT−). High-anxious participants tended to show faster acquisition of startle potentiation in the CXT+ versus the CXT− than low-anxious participants. This enhanced contextual fear learning might function as a risk factor for anxiety disorders that are characterized by sustained anxiety. PMID:23384512

Delayed HIV diagnosis among men who have sex with men (MSM) in the United States continues to be a significant personal and public health issue. Using qualitative and quantitative data from 75 recently tested, HIV-seropositive MSM (38 delayed and 37 non-delayed testers) we sought to further elucidate potential personal and contextual factors that may contribute to delayed HIV diagnosis among MSM. Our findings indicate MSM who experience multiple life stressors, whether personal or contextual, have an increased likelihood of delaying HIV diagnosis. Further, MSM experiencing multiple life stressors without the scaffolding of social support, stable mental health, and self-efficacy to engage in protective health behaviors may be particularly vulnerable to delaying diagnosis. Interventions targeting these factors as well as structural interventions targeting physiological and safety concerns are needed to help MSM handle their life stressors more effectively and seek HIV testing in a timelier manner.

Introduction Health sector management is increasingly complex as new health technologies, treatments, and innovative service delivery strategies are developed. Many of these innovations are implemented prematurely, or fail to be implemented at scale, resulting in substantial wasted resources.   Methods A scoping review was conducted to identify articles that described the scale up process conceptually or that described an instance in which a healthcare innovation was scaled up. We define scale up as the expansion and extension of delivery or access to an innovation for all end users in a jurisdiction who will benefit from it. Results Sixty nine articles were eligible for review. Frequently described stages in the innovation process and contextual issues that influence progress through each stage were mapped. 16 stages were identified: 12 deliberation and 4 action stages. Included papers suggest that innovations progress through stages of maturity and the uptake of innovation depends on the innovation aligning with the interests of 3 critical stakeholder groups (innovators, end users and the decision makers) and is also influenced by 3 broader contexts (social and physical environment, the health system, and the regulatory, political and economic environment). The 16 stages form the rows of the Nose to Tail Tool (NTT) grid and the 6 contingency factors form columns. The resulting stage-by-issue grid consists of 72 cells, each populated with cell-specific questions, prompts and considerations from the reviewed literature. Conclusion We offer a tool that helps stakeholders identify the stage of maturity of their innovation, helps facilitate deliberative discussions on the key considerations for each major stakeholder group and the major contextual barriers that the innovation faces. We believe the NTT will help to identify potential problems that the innovation will face and facilitates early modification, before large investments are made in a potentially flawed solution.

Global health issues vary in the amount of attention and resources they receive. One reason is that the networks of individuals and organizations that address these issues differ in their effectiveness. This article presents key findings from a research project on the emergence and effectiveness of global health networks addressing tobacco use, alcohol harm, maternal mortality, neonatal mortality, tuberculosis and pneumonia. Although networks are only one of many factors influencing priority, they do matter, particularly for shaping the way the problem and solutions are understood, and convincing governments, international organizations and other global actors to address the issue. Their national-level effects vary by issue and are more difficult to ascertain. Networks are most likely to produce effects when (1) their members construct a compelling framing of the issue, one that includes a shared understanding of the problem, a consensus on solutions and convincing reasons to act and (2) they build a political coalition that includes individuals and organizations beyond their traditional base in the health sector, a task that demands engagement in the politics of the issue, not just its technical aspects. Maintaining a focused frame and sustaining a broad coalition are often in tension: effective networks find ways to balance the two challenges. The emergence and effectiveness of a network are shaped both by its members' decisions and by contextual factors, including historical influences (e.g. prior failed attempts to address the problem), features of the policy environment (e.g. global development goals) and characteristics of the issue the network addresses (e.g. its mortality burden). Their proliferation raises the issue of their legitimacy. Reasons to consider them legitimate include their members' expertise and the attention they bring to neglected issues. Reasons to question their legitimacy include their largely elite composition and the fragmentation they bring to global health governance.

Inhibition of projections from the basolateral amygdala to the entorhinal cortex disrupts the acquisition of contextual fear

The development of excessive fear and/or stress responses to environmental cues such as contexts associated with a traumatic event is a hallmark of post-traumatic stress disorder (PTSD). The basolateral amygdala (BLA) has been implicated as a key structure mediating contextual fear conditioning. In addition, the hippocampus has an integral role in the encoding and processing of contexts associated with strong, salient stimuli such as fear. Given that both the BLA and hippocampus play an important role in the regulation of contextual fear conditioning, examining the functional connectivity between these two structures may elucidate a role for this pathway in the development of PTSD. Here, we used optogenetic strategies to demonstrate that the BLA sends a strong glutamatergic projection to the hippocampal formation through the entorhinal cortex (EC). Next, we photoinhibited glutamatergic fibers from the BLA terminating in the EC during the acquisition or expression of contextual fear conditioning. In mice that received optical inhibition of the BLA-to-EC pathway during the acquisition session, we observed a significant decrease in freezing behavior in a context re-exposure session. In contrast, we observed no differences in freezing behavior in mice that were only photoinhibited during the context re-exposure session. These data demonstrate an important role for the BLA-to-EC glutamatergic pathway in the acquisition of contextual fear conditioning. PMID:24834031

Contextualized science? An Indian experience

NASA Astrophysics Data System (ADS)

Koul, Ravinder

1997-11-01

This study asserts that science is contextualized and should therefore be taught as contextualized. Works of major philosophers in 20th century history, philosophy and sociology of science and recent developments in cognition are discussed in developing a foundation and outlining three themes for contextualized science: (a) science curriculum should emphasize scientific methodology through the generation and testing of knowledge in a specific context, (b) it should validate and evaluate everyday contextual experiences, and (c) develop a context for action by engaging in science, technology and society issues. School science is a major instrument for diffusion and utilization of scientific knowledge. In India, textbooks are often the only classroom source of information for students other than the teacher. The most widely used standard curriculum materials in Indian schools are the National Council of Educational Research and Training (NCERT) textbooks. For schools in the Hoshingabad district of Madhya Pradesh, the state prescribes NCERT materials and materials developed for the Hoshingabad Science Teaching Program (HSTP), a grassroots science education initiative. In this study, the investigation of these curriculum materials and interviews with educators (curriculum developers/textbook authors/teachers at New Delhi and Hoshingabad) are used to establish criteria for both the need and the feasibility of contextualized science. Results of the investigation indicate that the centralized NCERT system of curriculum development has undermined context specific treatment of subject matter in their textbooks. While HSTP attempted to contextualize science in rural schools, the present status of the program may be interpreted as either development and legitimization of another standardized curriculum, or, as the culmination of a gradual erosion and dissipation of conceptually valid and concrete educational practices. There are major situational and institutional constraints that impede the use of contextualized instructional materials. Furthermore, teachers' reflections on science in two curricula reveal limited conceptions on the nature of science and a preference for the abstract science of NCERT. The findings indicate that teacher understanding of methodological and epistemological point of view is essential but insufficient to provide a context for action. Teacher training must also incorporate ontological considerations in reform efforts to contextualize school science.

State of the art (DNA) sequencing methods applied in “Omics” studies grant insight into the ‘blueprints’ of organisms from all domains of life. Sequencing is carried out around the globe and the data is submitted to the public repositories of the International Nucleotide Sequence Database Collaboration. However, the context in which these studies are conducted often gets lost, because experimental data, as well as information about the environment are rarely submitted along with the sequence data. If these contextual or metadata are missing, key opportunities of comparison and analysis across studies and habitats are hampered or even impossible. To address this problem, the Genomic Standards Consortium (GSC) promotes checklists and standards to better describe our sequence data collection and to promote the capturing, exchange and integration of sequence data with contextual data. In a recent community effort the GSC has developed a series of recommendations for contextual data that should be submitted along with sequence data. To support the scientific community to significantly enhance the quality and quantity of contextual data in the public sequence data repositories, specialized software tools are needed. In this work we present CDinFusion, a web-based tool to integrate contextual and sequence data in (Multi)FASTA format prior to submission. The tool is open source and available under the Lesser GNU Public License 3. A public installation is hosted and maintained at the Max Planck Institute for Marine Microbiology at http://www.megx.net/cdinfusion.

Chronic pain can significantly impair functioning of children and adolescents; however, evidence suggests that current psychological approaches have limited effect on functioning post treatment. The objective of this review is to present the current evidence for the personal and contextual factors that affect functioning and disability of children and adolescents with chronic pain, to support the evolution of new treatments. Key word searches were conducted in PsycINFO, MEDLINE via Ovid, CINAHL, and PubMed from 1995 to October 2014. Studies were included if they (1) were written in English, (2) included children or adolescents with chronic pain (>3 mo), (3) had at least 1 personal attribute or 1 contextual factor, (4) had 1 measure of functional ability, and (5) had reported correlations between personal or contextual factors and functional measure. Thirty-three studies were identified which met all inclusion criteria. Several personal factors (depression, anxiety, pain intensity, and catastrophizing) and contextual/environmental factors (parenting characteristics) were consistently associated with higher levels of disability, whereas evidence for other factors was less consistent. Complex interactions between personal and contextual factors were reported. Child physical/cognitive capacities, teacher/peer behaviors, and broader cultural and environmental social systems, received little attention. Several parent and child factors were consistently linked with functional disability, whereas better family functioning was associated with functional ability. Applying an ecological framework, assisted identification of areas for further research, and provides direction for treatments that may be more effective in optimizing long-term functional outcomes, extending current psychological approaches.

Role of contextual cues on the perception of spectrally reduced interrupted speech.

PubMed

Patro, Chhayakanta; Mendel, Lisa Lucks

Understanding speech within an auditory scene is constantly challenged by interfering noise in suboptimal listening environments when noise hinders the continuity of the speech stream. In such instances, a typical auditory-cognitive system perceptually integrates available speech information and "fills in" missing information in the light of semantic context. However, individuals with cochlear implants (CIs) find it difficult and effortful to understand interrupted speech compared to their normal hearing counterparts. This inefficiency in perceptual integration of speech could be attributed to further degradations in the spectral-temporal domain imposed by CIs making it difficult to utilize the contextual evidence effectively. To address these issues, 20 normal hearing adults listened to speech that was spectrally reduced and spectrally reduced interrupted in a manner similar to CI processing. The Revised Speech Perception in Noise test, which includes contextually rich and contextually poor sentences, was used to evaluate the influence of semantic context on speech perception. Results indicated that listeners benefited more from semantic context when they listened to spectrally reduced speech alone. For the spectrally reduced interrupted speech, contextual information was not as helpful under significant spectral reductions, but became beneficial as the spectral resolution improved. These results suggest top-down processing facilitates speech perception up to a point, and it fails to facilitate speech understanding when the speech signals are significantly degraded.

Frameworks for evaluating health research capacity strengthening: a qualitative study

PubMed Central

2013-01-01

Background Health research capacity strengthening (RCS) projects are often complex and hard to evaluate. In order to inform health RCS evaluation efforts, we aimed to describe and compare key characteristics of existing health RCS evaluation frameworks: their process of development, purpose, target users, structure, content and coverage of important evaluation issues. A secondary objective was to explore what use had been made of the ESSENCE framework, which attempts to address one such issue: harmonising the evaluation requirements of different funders. Methods We identified and analysed health RCS evaluation frameworks published by seven funding agencies between 2004 and 2012, using a mixed methods approach involving structured qualitative analyses of documents, a stakeholder survey and consultations with key contacts in health RCS funding agencies. Results The frameworks were intended for use predominantly by the organisations themselves, and most were oriented primarily towards funders’ internal organisational performance requirements. The frameworks made limited reference to theories that specifically concern RCS. Generic devices, such as logical frameworks, were typically used to document activities, outputs and outcomes, but with little emphasis on exploring underlying assumptions or contextual constraints. Usage of the ESSENCE framework appeared limited. Conclusions We believe that there is scope for improving frameworks through the incorporation of more accessible information about how to do evaluation in practice; greater involvement of stakeholders, following evaluation capacity building principles; greater emphasis on explaining underlying rationales of frameworks; and structuring frameworks so that they separate generic and project-specific aspects of health RCS evaluation. The third and fourth of these improvements might assist harmonisation. PMID:24330628

Semantic Web and Contextual Information: Semantic Network Analysis of Online Journalistic Texts

NASA Astrophysics Data System (ADS)

Lim, Yon Soo

This study examines why contextual information is important to actualize the idea of semantic web, based on a case study of a socio-political issue in South Korea. For this study, semantic network analyses were conducted regarding English-language based 62 blog posts and 101 news stories on the web. The results indicated the differences of the meaning structures between blog posts and professional journalism as well as between conservative journalism and progressive journalism. From the results, this study ascertains empirical validity of current concerns about the practical application of the new web technology, and discusses how the semantic web should be developed.

Fostering ethical willingness: integrating emotional and contextual awareness with rational analysis.

Betan, E J; Stanton, A L

Ethical dilemmas are inherently challenging. By definition, clinicians decide between conflicting principles of welfare and naturally confront competing pulls and inclinations. This investigation of students' responses to an ethical scenario highlights how emotions and concerns can interfere with willingness to implement ethical knowledge. Clear-cut rules are the exception in psychotherapy, and clinicians must judge ethical issues on the basis of the unique context of each case. As such, subjectivity and emotional involvement are essential tools for determining ethical action, but they must be integrated with rational analysis. Strategies for attending to influential emotions and contextual factors in order to mobilize ethical commitment are described.

Scaling and contextualizing climate-conflict nexus in historical agrarian China

NASA Astrophysics Data System (ADS)

Lee, Harry F.

2017-04-01

This study examines climate-conflict nexus in historical agrarian China in multi-scalar and contextualized approach, illustrating what and how socio-political factors could significantly mediate the climate-violent link in pre-industrial society. Previous empirical large-N studies show that violent conflict in historical agrarian society was triggered by climate-induced food scarcity. The relationship was valid in China, Europe, and various geographic regions in the Northern Hemisphere in pre-industrial era. Nevertheless, the observed relationship has only been verified at a macro level (long-term variability of the nexus is emphasized and data over large area are aggregated), and somewhat generalized in nature (only physical environmental factors are controlled). Three inter-related issues remain unresolved: First, the key explanatory variable of violent conflicts may change substantially at different spatio-temporal scales. It is necessary to check whether the climate-conflict nexus is valid at a micro level (about short-term variability of the nexus and data in finer spatial resolution), and explore how the nexus changes along various spatio-temporal dimensions. Second, as the climate-conflict nexus has only been demonstrated in a broad sense, it is necessary to check whether and how the nexus is mediated by local socio-political context. More non-climatic factors pertinent to the cause and distribution of conflicts (e.g., governance, adaptive mechanisms, etc.) should be considered. Third, the methodology applied in the previous studies assumes spatially-independent observations and linear relationship, which may simplify the climate-conflict link. Moreover, the solitary reliance on quantitative methods may neglect those non-quantifiable socio-political dynamics which mediates the climate-conflict nexus. I plan to address the above issues by using disaggregated spatial analysis and in-depth case studies, with close attention to local and temporal differences and non-linear nature of the climate-conflict link. China will be chosen as study area. Study period will be delimited to AD1-1911. This study represents pioneering research which systematically examines the climate-conflict nexus in pre-industrial society over extended period in multi-scalar and contextualized perspective. By comparing and evaluating the climate-conflict link along various spatio-temporal dimensions and in different socio-political context, it may help to deepen the theoretical understanding of, and also resolve the current debate over, the climate-conflict relationship. Given the large potential changes in climatic regimes projected in coming decades, the findings in this study may have important implications for the social impact of climate change in tropical countries that are in some ways similar to pre-industrial society.

A prospective multiple case study of the impact of emerging scientific evidence on established colorectal cancer screening programs: a study protocol.

2012-06-01

Health-policy decision making is a complex and dynamic process, for which strong evidentiary support is required. This includes scientifically produced research, as well as information that relates to the context in which the decision takes place. Unlike scientific evidence, this "contextual evidence" is highly variable and often includes information that is not scientifically produced, drawn from sources such as political judgement, program management experience and knowledge, or public values. As the policy decision-making process is variable and difficult to evaluate, it is often unclear how this heterogeneous evidence is identified and incorporated into "evidence-based policy" decisions. Population-based colorectal cancer screening poses an ideal context in which to examine these issues. In Canada, colorectal cancer screening programs have been established in several provinces over the past five years, based on the fecal occult blood test (FOBT) or the fecal immunochemical test. However, as these programs develop, new scientific evidence for screening continues to emerge. Recently published randomized controlled trials suggest that the use of flexible sigmoidoscopy for population-based screening may pose a greater reduction in mortality than the FOBT. This raises the important question of how policy makers will address this evidence, given that screening programs are being established or are already in place. This study will examine these issues prospectively and will focus on how policy makers monitor emerging scientific evidence and how both scientific and contextual evidence are identified and applied for decisions about health system improvement. This study will employ a prospective multiple case study design, involving participants from Ontario, Alberta, Manitoba, Nova Scotia, and Quebec. In each province, data will be collected via document analysis and key informant interviews. Documents will include policy briefs, reports, meeting minutes, media releases, and correspondence. Interviews will be conducted in person with senior administrative leaders, government officials, screening experts, and high-level cancer system stakeholders. The proposed study comprises the third and final phase of an Emerging Team grant to address the challenges of health-policy decision making and colorectal cancer screening decisions in Canada. This study will contribute a unique prospective look at how policy makers address new, emerging scientific evidence in several different policy environments and at different stages of program planning and implementation. Findings will provide important insight into the various approaches that are or should be used to monitor emerging evidence, the relative importance of scientific versus contextual evidence for decision making, and the tools and processes that may be important to support challenging health-policy decisions.

Contextualizing Competence: Language and LGBT-Based Competency in Health Care.

Rossi, Alexis L; Lopez, Eliot J

2017-01-01

Changes in the language and terminology used to refer to individuals identifying as lesbian, gay, bisexual, and transgender (LGBT), as well as how best to discuss issues of sexual and gender identity, can prove challenging for health care providers due to (1) lack of training; (2) interdisciplinary issues; and (3) prejudices on personal and institutional levels. Given the importance of language in the relationship between health care provider and patient as well as the myriad ways in which language can reflect knowledge, skills, and attitudes, we contend that language is both a facilitator and inhibitor of competence. In this article, we discuss language as a means of exhibiting cultural competence as well as the barriers to facilitating this degree of competence. Communicative competence, a concept traditionally used in linguistics, is discussed as a framework for contextualizing LGBT-specific cultural competence in health care. Ideally, a professional will be considered competent once they (1) acquire a foundation in issues associated with LGBT individuals, as well as a basic understanding of appropriate vocabulary' (2) reconcile personal beliefs with their professional role; (3) create an inclusive healthcare environment such that the influence of personal biases does not negatively impact care; and (4) use identifiers suggested by the patient.

Put a Frame on It: Contextualizing Climate Change for Museum Visitors

NASA Astrophysics Data System (ADS)

Canning, Katharine

Public opinion polls continue to show that Americans are divided---particularly along political and ideological lines---on whether climate change is real and warrants immediate action. Those in the natural and social sciences have recognized that effective communication is key to closing the gap that exists between scientific and public understanding on this issue. A body of social science research on climate change communication has emerged within the last decade. This field has identified strategies for climate change communicators and educators, emphasizing the importance of framing climate change issues in ways that help it resonate with a wider range of public concerns and values in order to develop a shared belief regarding the necessity of action. Museum exhibits and programs on climate change that were developed within the last five years are likely to have benefitted from this body of work. This qualitative research seeks to examine and analyze the various ways museums in the United States are communicating about climate change related issues to the public. Three case studies of museum exhibits on climate change issues were examined. The scope and purpose of climate change communication in museums, the specific messages that museums are choosing to communicate, and how those messages are being framed for public audiences were explored through these case studies. The findings suggest that museums are considering their audience when framing messages about climate change and have used work from the climate change communication field to inform message development. In particular, museums are making climate change issues more relevant by emphasizing social, economic, and human health concerns, and are considering strategies to counteract fear-fatigue and empower visitors to take action.

Chinese Sentence Classification Based on Convolutional Neural Network

Gu, Chengwei; Wu, Ming; Zhang, Chuang

2017-10-01

Sentence classification is one of the significant issues in Natural Language Processing (NLP). Feature extraction is often regarded as the key point for natural language processing. Traditional ways based on machine learning can not take high level features into consideration, such as Naive Bayesian Model. The neural network for sentence classification can make use of contextual information to achieve greater results in sentence classification tasks. In this paper, we focus on classifying Chinese sentences. And the most important is that we post a novel architecture of Convolutional Neural Network (CNN) to apply on Chinese sentence classification. In particular, most of the previous methods often use softmax classifier for prediction, we embed a linear support vector machine to substitute softmax in the deep neural network model, minimizing a margin-based loss to get a better result. And we use tanh as an activation function, instead of ReLU. The CNN model improve the result of Chinese sentence classification tasks. Experimental results on the Chinese news title database validate the effectiveness of our model.

Methodology or method? A critical review of qualitative case study reports.

Hyett, Nerida; Kenny, Amanda; Dickson-Swift, Virginia

2014-01-01

Despite on-going debate about credibility, and reported limitations in comparison to other approaches, case study is an increasingly popular approach among qualitative researchers. We critically analysed the methodological descriptions of published case studies. Three high-impact qualitative methods journals were searched to locate case studies published in the past 5 years; 34 were selected for analysis. Articles were categorized as health and health services (n=12), social sciences and anthropology (n=7), or methods (n=15) case studies. The articles were reviewed using an adapted version of established criteria to determine whether adequate methodological justification was present, and if study aims, methods, and reported findings were consistent with a qualitative case study approach. Findings were grouped into five themes outlining key methodological issues: case study methodology or method, case of something particular and case selection, contextually bound case study, researcher and case interactions and triangulation, and study design inconsistent with methodology reported. Improved reporting of case studies by qualitative researchers will advance the methodology for the benefit of researchers and practitioners.

Despite a wealth of intervention research in cancer control, full integration of evidence-based interventions into practice often fails, at least in part because of inadequate collaboration between practitioners and researchers. The National Cancer Institute piloted a mentorship program designed for practitioners to improve their ability to navigate evidence-based decision making within a context of inadequate resources, political barriers, and organizational constraints. The National Cancer Institute simultaneously sought to provide opportunities for practitioners and researchers to share and learn from each other. We identified four key successes and challenges related to translation as experienced by mentees: (a) establishing and maintaining partnerships, (b) data collection and analysis, (c) navigating context, and (d) program adaptation and evaluation. Mentorship programs have the potential to facilitate increased and more successful integration of evidence-based interventions into practice by promoting and building the capacity for collaborative decision making and generating in-depth understanding of the translation barriers and successes as well as strategies to address the complex contextual issues relative to implementation.

The Social Context Network Model in Psychiatric and Neurological Diseases.

PubMed

Baez, Sandra; García, Adolfo M; Ibanez, Agustín

2017-01-01

The role of contextual modulations has been extensively studied in basic sensory and cognitive processes. However, little is known about their impact on social cognition, let alone their disruption in disorders compromising such a domain. In this chapter, we flesh out the social context network model (SCNM), a neuroscientific proposal devised to address the issue. In SCNM terms, social context effects rely on a fronto-temporo-insular network in charge of (a) updating context cues to make predictions, (b) consolidating context-target associative learning, and (c) coordinating internal and external milieus. First, we characterize various social cognition domains as context-dependent phenomena. Then, we review behavioral and neural evidence of social context impairments in behavioral variant frontotemporal dementia (bvFTD) and autism spectrum disorder (ASD), highlighting their relation with key SCNM hubs. Next, we show that other psychiatric and neurological conditions involve context-processing impairments following damage to the brain regions included in the model. Finally, we call for an ecological approach to social cognition assessment, moving beyond widespread abstract and decontextualized methods.

The contextual issues associated with sexual harassment experiences reported by registered nurses.

PubMed

Madison, Jeanne; Minichiello, Victor

The study aimed to explore contextual conditions in Australian health care workplaces that make sex-based and sexual harassment (SB&SH) a relatively common experience for registered nurses (RNs). Unstructured, in-depth interviews with a convenience sample of Australian RNs. The informants were 16 RNs (15 female and one male), working in health care, who were students enrolled in advanced tertiary preparation in nursing, counselling, and health care management at an Australian university. Experiences described by the interview informants identified four conditions present in their workplace when they experienced SB&SH.

Many methodological approaches have been used to understand cultural dimensions to maternal health issues. Although a well-designed quantitative survey with a representative sample can provide essential information on trends in behavior, it does not necessarily establish a contextualized understanding of the complexity in which different behaviors occur. This article addresses how contextualized data can be collected in a short time and under conditions in which participants in conflict-affected zones might not have established, or time to establish, trust with the researchers. The solution, the Participatory Ethnographic Evaluation and Research (PEER) approach, is illustrated through a study whereby South Sudanese marginalized women were trained to design research instruments, and collect and analyze qualitative data. PEER overcomes the problem that many ethnographic or participatory approaches face—the extensive time and resources required to develop trusting relationships with the community to understand the local context and the social networks they form.

The Trans-Contextual Model of Autonomous Motivation in Education: Conceptual and Empirical Issues and Meta-Analysis.

PubMed

Hagger, Martin S; Chatzisarantis, Nikos L D

2016-06-01

The trans-contextual model outlines the processes by which autonomous motivation toward activities in a physical education context predicts autonomous motivation toward physical activity outside of school, and beliefs about, intentions toward, and actual engagement in, out-of-school physical activity. In the present article, we clarify the fundamental propositions of the model and resolve some outstanding conceptual issues, including its generalizability across multiple educational domains, criteria for its rejection or failed replication, the role of belief-based antecedents of intentions, and the causal ordering of its constructs. We also evaluate the consistency of model relationships in previous tests of the model using path-analytic meta-analysis. The analysis supported model hypotheses but identified substantial heterogeneity in the hypothesized relationships across studies unattributed to sampling and measurement error. Based on our meta-analysis, future research needs to provide further replications of the model in diverse educational settings beyond physical education and test model hypotheses using experimental methods.

Factors affecting graded and ungraded memory loss following hippocampal lesions.

Winocur, Gordon; Moscovitch, Morris; Sekeres, Melanie J

2013-11-01

This review evaluates three current theories--Standard Consolidation (Squire & Wixted, 2011), Overshadowing (Sutherland, Sparks, & Lehmann, 2010), and Multiple Trace-Transformation (Winocur, Moscovitch, & Bontempi, 2010)--in terms of their ability to account for the role of the hippocampus in recent and remote memory in animals. Evidence, based on consistent findings from tests of spatial memory and memory for acquired food preferences, favours the transformation account, but this conclusion is undermined by inconsistent results from studies that measured contextual fear memory, probably the most commonly used test of hippocampal involvement in anterograde and retrograde memory. Resolution of this issue may depend on exercising greater control over critical factors (e.g., contextual environment, amount of pre-exposure to the conditioning chamber, the number and distribution of foot-shocks) that can affect the representation of the memory shortly after learning and over the long-term. Research strategies aimed at characterizing the neural basis of long-term consolidation/transformation, as well as other outstanding issues are discussed. Copyright © 2013 Elsevier Inc.

Ecological theories of systems and contextual change in medical education.

PubMed

Ellaway, Rachel H; Bates, Joanna; Teunissen, Pim W

2017-12-01

Contemporary medical practice is subject to many kinds of change, to which both individuals and systems have to respond and adapt. Many medical education programmes have their learners rotating through different training contexts, which means that they too must learn to adapt to contextual change. Contextual change presents many challenges to medical education scholars and practitioners, not least because of a somewhat fractured and contested theoretical basis for responding to these challenges. There is a need for robust concepts to articulate and connect the various debates on contextual change in medical education. Ecological theories of systems encompass a range of concepts of how and why systems change and how and why they respond to change. The use of these concepts has the potential to help medical education scholars explore the nature of change and understand the role it plays in affording as well as limiting teaching and learning. This paper, aimed at health professional education scholars and policy makers, explores a number of key concepts from ecological theories of systems to present a comprehensive model of contextual change in medical education to inform theory and practice in all areas of medical education. The paper considers a range of concepts drawn from ecological theories of systems, including biotic and abiotic factors, panarchy, attractors and repellers, basins of attraction, homeostasis, resilience, adaptability, transformability and hysteresis. Each concept is grounded in practical examples from medical education. Ecological theories of systems consider change and response in terms of adaptive cycles functioning at different scales and speeds. This can afford opportunities for systematic consideration of responses to contextual change in medical education, which in turn can inform the design of education programmes, activities, evaluations, assessments and research that accommodates the dynamics and consequences of contextual change. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

The influence of contextual factors on patient involvement during follow-up consultations after colorectal cancer surgery: a case study.

To identify the contextual factors that influence individual patient involvement during colorectal cancer surgical follow-up consultations. The healthcare system is subject to the requirement and expectation of greater involvement of patients and relatives. Increased patient involvement requires the development and implementation of new communication initiatives. Research shows that it is also necessary to consider the contextual circumstances surrounding patient involvement in specific situations. Case study of a single Danish outpatient clinic, which allows the issues and circumstances involved in an everyday situation to be captured. 12 nonparticipative observations of outpatient visits and, subsequently, seven in-depth patient interviews. Content analysis based on a dialogical, interactive framework, which underpinned the identification of current contextual factors. The results showed five contextual factors that seemed to have an impact on patient involvement. The first, 'Two dimensions of patient involvement: treatment-oriented and person-oriented' highlighted a dual interpretation of patient involvement in the consultation situation. The two dimensions seemed to be influenced by four additional factors: 'Doctors leading the agenda', 'Traditional health professional roles', 'Unclear responsibilities' and 'Guidance primarily focused on treatment'. The results showed how patient involvement in clinical practice could be understood as a two-way movement, in which patients are invited to participate in clinical practice, while health professionals are invited to participate in the patients' lives. The movement will change from situation to situation and is influenced by several contextual factors. The results can help doctors and nurses to navigate using a goal-oriented approach towards patient involvement. The study makes visible the need for research-based development of the independent role of the nursing profession in cancer care follow-up, with a view to enhanced patient-centred care. © 2017 John Wiley & Sons Ltd.

Organizational Failure in an NHS Hospital Trust: A Qualitative Study.

Ravaghi, Hamid; Mannion, Russell; Sajadi, Haniye Sadat

2015-01-01

The objective was to explore the key factors associated with organizational failure in an NHS Hospital Trust. This case study adopted a qualitative design. Fifty-seven semistructured interviews and document analyses were conducted as well. Data were analyzed using a framework analysis method. A range of symptoms of organizational performance failure was identified. These relate to a financial deficit, lack of good external relationships, inability to meet core targets, a lack of clear management systems, and low staff morale. These markers had not been taken seriously by the previous senior management team. Symptoms of failure were the reflection of presence of secondary and primary causes of failure. Poor managerial leadership, poor financial control and performance management, lack of open culture, distraction by 2 large projects, and the lack of clinician engagement were perceived as internal causes of failure and the high level of policy changes within the NHS as the key external cause. The level of deprivation in the area was also thought to have had a negative impact on performance. The findings reinforce and expand on those of recent studies across the public sector. Tracking an organization's performance and early diagnosis of performance problems, focusing on performance management systems, and taking into account contextual factors are issues that should be considered.

Health committees, councils or boards (HCs) mediate between communities and health services in many health systems. Despite their widespread prevalence, HC functions vary due to their diversity and complexity, not least because of their context specific nature. We undertook a narrative review to better understand the contextual features relevant to HCs, drawing from Scopus and the internet. We found 390 English language articles from journals and grey literature since 1996 on health committees, councils and boards. After screening with inclusion and exclusion criteria, we focused on 44 articles. Through an iterative process of exploring previous attempts at understanding context in health policy and systems research (HPSR) and the HC literature, we developed a conceptual framework that delineates these contextual factors into four overlapping spheres (community, health facilities, health administration, society) with cross-cutting issues (awareness, trust, benefits, resources, legal mandates, capacity-building, the role of political parties, non-governmental organizations, markets, media, social movements and inequalities). While many attempts at describing context in HPSR result in empty arenas, generic lists or amorphous detail, we suggest anchoring an understanding of context to a conceptual framework specific to the phenomena of interest. By doing so, our review distinguishes between contextual elements that are relatively well understood and those that are not. In addition, our review found that contextual elements are dynamic and porous in nature, influencing HCs but also being influenced by them due to the permeability of HCs. While reforms focus on tangible HC inputs and outputs (training, guidelines, number of meetings held), our review of contextual factors highlights the dynamic relationships and broader structural elements that facilitate and/or hinder the role of health committees in health systems. Such an understanding of context points to its contingent and malleable nature, links it to theorizing in HPSR, and clarifies areas for investigation and action. Copyright © 2015.

What makes you tic? Translational approaches to study the role of stress and contextual triggers in Tourette syndrome

PubMed Central

Godar, Sean C; Bortolato, Marco

2016-01-01

Tourette syndrome (TS) is a neurodevelopmental condition characterized by multiple, recurring motor and phonic tics. Rich empirical evidence shows that the severity of tics and associated manifestations is increased by several stressors and contextual triggers; however, the neurobiological mechanisms responsible for symptom exacerbation in TS remain poorly understood. This conceptual gap partially reflects the high phenotypic variability in tics, as well as the existing difficulties in operationalizing and standardizing stress and its effects in a clinical setting. Animal models of TS may be highly informative tools to overcome some of these limitations; these experimental preparations have already provided critical insights on key aspects of TS pathophysiology, and may prove useful to identify the neurochemical alterations induced by different stressful contingencies. In particular, emerging knowledge on the role of contextual triggers in animal models of TS may inform the development of novel pharmacological interventions to reduce tic fluctuations in this disorder.

Behavioral interference elicited by competing response tendencies adapts to contextual changes. Recent nonhuman primate research suggests a key mnemonic role of distinct prefrontal cells in supporting such context-driven behavioral adjustments by maintaining conflict information across trials, but corresponding prefrontal functions have yet to be probed in humans. Using event-related functional magnetic resonance imaging, we investigated the human neural substrates of contextual adaptations to conflict. We found that a neural system comprising the rostral dorsomedial prefrontal cortex and portions of the dorsolateral prefrontal cortex specifically encodes the history of previously experienced conflict and influences subsequent adaptation to conflict on a trial-by-trial basis. This neural system became active in anticipation of stimulus onsets during preparatory periods and interacted with a second neural system engaged during the processing of conflict. Our findings suggest that a dynamic interaction between a system that represents conflict history and a system that resolves conflict underlies the contextual adaptation to conflict.

Orleans, C T

1999-01-01

This article highlights key contextual factors that emerge when the evolution of tailored health communications is viewed against the backdrop of dynamic changes in the nation's health care system--including the shift from fee-for-service medicine to managed care and the proliferation of direct-to-consumer and tailored marketing strategies in the pharmaceutical industry. It focuses on contextual variables with potential to significantly mediate the impact of personally tailored health advice--including those related to confidentiality, privacy, and informed consent and to the perceived aims, intents, and sources of tailored health messages. To protect the future of tailored health messages, more research attention must be given to defining these contextual factors and understanding the roles that they play and the ways in which they can be controlled to assure the best outcomes. Such research could point the way towards a set of empirical and ethical "best practices" based on a scientific understanding of how to maximize the benefits, and minimize the potential harms, of the widescale use of tailored health communications.

Spine growth in the anterior cingulate cortex is necessary for the consolidation of contextual fear memory

Remodeling of cortical connectivity is thought to allow initially hippocampus-dependent memories to be expressed independently of the hippocampus at remote time points. Consistent with this, consolidation of a contextual fear memory is associated with dendritic spine growth in neurons of the anterior cingulate cortex (aCC). To directly test whether such cortical structural remodeling is necessary for memory consolidation, we disrupted spine growth in the aCC at different times following contextual fear conditioning in mice. We took advantage of previous studies showing that the transcription factor myocyte enhancer factor 2 (MEF2) negatively regulates spinogenesis both in vitro and in vivo. We found that increasing MEF2-dependent transcription in the aCC during a critical posttraining window (but not at later time points) blocked both the consolidation-associated dendritic spine growth and subsequent memory expression. Together, these data strengthen the causal link between cortical structural remodeling and memory consolidation and, further, identify MEF2 as a key regulator of these processes. PMID:21531906

Rapid contextual conditioning in autoshaping.

Balsam, P D; Schwartz, A L

1981-10-01

Two experiments are reported which investigate the speed of contextual conditioning in autoshaping. In both experiments, a procedure was employed in which ring doves were magazine trained in one context prior to the manipulation of background values in a second context. In Experiment 1, subjects were exposed to 4, 8, 64, 128, or 256 US-only presentations prior to autoshaping. Acquisition speed and maintained response measures were monotonically related to the number of pretraining trials. Subjects in Group 4 acquired the key-peck response fastest, and retardation was maximal within 64 pretraining trials. In Experiment 2, subjects given 20 pretraining trials were significantly more retarded than subjects given 2 pretraining trials, but only when pretraining and testing were conducted in the same context. Overall, the results of these experiments show that in autoshaping, contextual conditioning is very rapid; this demonstrates the plausibility of theoretical accounts of Pavlovian conditioning which assert that the development of the conditioned response depends on the associative values of both the CS and background stimuli.

Selective attention determines the effectiveness of implicit contextual learning (e.g., Jiang and Leung, 2005). Visual foreground-background segmentation, on the other hand, is a key process in the guidance of attention (Wolfe, 2003). In the present study, we examined the impact of foreground-background segmentation on contextual cueing of visual search in three experiments. A visual search display, consisting of distractor 'L's and a target 'T', was overlaid on a task-neutral cuboid on the same depth plane (Experiment 1), on stereoscopically separated depth planes (Experiment 2), or spread over the entire display on the same depth plane (Experiment 3). Half of the search displays contained repeated target-distractor arrangements, whereas the other half was always newly generated. The task-neutral cuboid was constant during an initial training session, but was either rotated by 90° or entirely removed in the subsequent test sessions. We found that the gains resulting from repeated presentation of display arrangements during training (i.e., contextual-cueing effects) were diminished when the cuboid was changed or removed in Experiment 1, but remained intact in Experiments 2 and 3 when the cuboid was placed in a different depth plane, or when the items were randomly spread over the whole display but not on the edges of the cuboid. These findings suggest that foreground-background segmentation occurs prior to contextual learning, and only objects/arrangements that are grouped as foreground are learned over the course of repeated visual search.

Awareness in contextual cueing of visual search as measured with concurrent access- and phenomenal-consciousness tasks.

PubMed

Schlagbauer, Bernhard; Müller, Hermann J; Zehetleitner, Michael; Geyer, Thomas

2012-10-25

In visual search, context information can serve as a cue to guide attention to the target location. When observers repeatedly encounter displays with identical target-distractor arrangements, reaction times (RTs) are faster for repeated relative to nonrepeated displays, the latter containing novel configurations. This effect has been termed "contextual cueing." The present study asked whether information about the target location in repeated displays is "explicit" (or "conscious") in nature. To examine this issue, observers performed a test session (after an initial training phase in which RTs to repeated and nonrepeated displays were measured) in which the search stimuli were presented briefly and terminated by visual masks; following this, observers had to make a target localization response (with accuracy as the dependent measure) and indicate their visual experience and confidence associated with the localization response. The data were examined at the level of individual displays, i.e., in terms of whether or not a repeated display actually produced contextual cueing. The results were that (a) contextual cueing was driven by only a very small number of about four actually learned configurations; (b) localization accuracy was increased for learned relative to nonrepeated displays; and (c) both consciousness measures were enhanced for learned compared to nonrepeated displays. It is concluded that contextual cueing is driven by only a few repeated displays and the ability to locate the target in these displays is associated with increased visual experience.

Memory under pressure: secondary-task effects on contextual cueing of visual search.

Repeated display configurations improve visual search. Recently, the question has arisen whether this contextual cueing effect (Chun & Jiang, 1998) is itself mediated by attention, both in terms of selectivity and processing resources deployed. While it is accepted that selective attention modulates contextual cueing (Jiang & Leung, 2005), there is an ongoing debate whether the cueing effect is affected by a secondary working memory (WM) task, specifically at which stage WM influences the cueing effect: the acquisition of configural associations (e.g., Travis, Mattingley, & Dux, 2013) versus the expression of learned associations (e.g., Manginelli, Langer, Klose, & Pollmann, 2013). The present study re-investigated this issue. Observers performed a visual search in combination with a spatial WM task. The latter was applied on either early or late search trials--so as to examine whether WM load hampers the acquisition of or retrieval from contextual memory. Additionally, the WM and search tasks were performed either temporally in parallel or in succession--so as to permit the effects of spatial WM load to be dissociated from those of executive load. The secondary WM task was found to affect cueing in late, but not early, experimental trials--though only when the search and WM tasks were performed in parallel. This pattern suggests that contextual cueing involves a spatial WM resource, with spatial WM providing a workspace linking the current search array with configural long-term memory; as a result, occupying this workspace by a secondary WM task hampers the expression of learned configural associations.

Contextual analysis of coping: implications for immigrants' mental health care.

PubMed

Donnelly, Tam Truong

2002-01-01

Providing high quality and effective health care services that are culturally acceptable and appropriate to clients has become an important issue for many health care providers. This paper explores problems associated with the traditional model that views coping according to hierarchical style and traits. While some scholars who have adopted this theoretical framework have made many contributions to the development of stress and coping theories, limitations are present. Using Vietnamese immigrants' experiences as examples, I argue that coping theories should emphasize the contextual nature of stress and coping, and that coping should be viewed as a dynamic process that varies under different social, cultural, political, economic, and historical conditions. Drawing from the work of others on coping, culture, imperialism, and colonialism, I explore the way that certain cultural conceptualizations determine how individuals cope. An understanding of the contextual nature of coping and of a Vietnamese immigrant's experience of coping with stressors and illness has implications for mental health care practice and research.

Cognitive and contextual correlates of spontaneous and deliberate mind-wandering.

PubMed

Robison, Matthew K; Unsworth, Nash

2018-01-01

Individuals with greater cognitive abilities generally show reduced rates of mind-wandering when completing relatively demanding tasks (Randall, Oswald, & Beier, 2014). However, it is yet unclear whether elevated rates of mind-wandering among low-ability individuals are manifestations of deliberate, intentional episodes of mind-wandering because of task disengagement or lack of motivation, or to spontaneous, unintentional failures to maintain task-oriented attention. The present study examined this issue by measuring working memory capacity (WMC), mind-wandering during 3 relatively demanding attention control tasks, and contextual variables (e.g., motivation, alertness, perceptions of task unpleasantness). Results indicated that the relationship between WMC and mind-wandering was primarily driven by spontaneous episodes. Lack of alertness also uniquely predicted more frequent spontaneous mind-wandering independently of WMC. Deliberate mind-wandering was primarily driven by a lack of motivation. Thus, cognitive and contextual factors can have distinct relationships with spontaneous and deliberate mind-wandering. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Synthesize the findings from individual qualitative studies about surgeons' account of their practice. Social and contextual factors of practice influence doctors' well-being and therapeutic relationships. Little is known about surgery, but it is generally assumed that surgeons are not affected by them. We searched international publications (2000-2012) to identify relevant qualitative research exploring how surgeons talk about their practice. Meta-ethnography (a systematic analysis of qualitative literature that compensates for the potential lack of generalizability of the primary studies and provides new insight by their conjoint interpretation) was used to identify key themes and synthesize them. We identified 51 articles (>1000 surgeons) from different specialties and countries. Two main themes emerged. (i) The patient-surgeon relationship, described surgeons' characterizations of their relationships with patients. We identified factors influencing surgical decision making, communication, and personal involvement in the process of care; these were surgeon-related, patient-related, and contextual. (ii) Group relations and culture described perceived issues related to surgical culture (image and education, teamwork, rules, and guidelines); it highlighted the influence of a social dimension on surgical practice. In both themes, we uncovered an emotional dimension of surgeons' practice. Surgeons' emphasis on technical aspects, individuality, and performance seems to impede a modern patient-centered approach to care and to act as a barrier to well-being. Our findings suggest that taking into account the relational and emotional dimensions of surgical practice (both with patients and within the institution) might improve surgical innovation, surgeons' well-being, and the attractiveness of this specialty.

A major global pedagogical shift has occurred in the way medicine is taught over the last half a century.

To examine the evolution and educational principles of PBL and the feasibility of implementing it in the West African subregion. Key literature detailing the history, educational value and principle behind PBL were reviewed. Issues regarding the implication of implementing PBL to West Africa were deduced and suggestions made for the way forward. Since its introduction in McMaster University in Canada in the 60s, PBL has spread all over world. It is rooted in sound educational theories like the Kolb's experiential learning, adult education, collaborative learning, contextual learning and constructivism. Compared to traditionally trained students, PBL students find learning more enjoyable and develop better relational and professional skills. They show more causal reasoning in diagnosis and become better lifelong learners. Issues that may affect its implementation in West Africa include high start up costs, lack of supporting educational technology and relative lack of medical school managers with appropriate medical education background to assess and evaluate such innovations. The evidence for the need for a change from the traditional method of training is overwhelming. Implementation of PBL as an educational method in medical training in the West African subregion is both desirable and practicable if we address some of the issues outlined above.

Contextual Uncertainties, Human Mobility, and Perceived Food Environment: The Uncertain Geographic Context Problem in Food Access Research.

PubMed

Chen, Xiang; Kwan, Mei-Po

2015-09-01

We examined the uncertainty of the contextual influences on food access through an analytic framework of the uncertain geographic context problem (UGCoP). We first examined the compounding effects of two kinds of spatiotemporal uncertainties on people's everyday efforts to procure food and then outlined three key dimensions (food access in real time, temporality of the food environment, and perceived nutrition environment) in which research on food access must improve to better represent the contributing environmental influences that operate at the individual level. Guidelines to address the UGCoP in future food access research are provided to account for the multidimensional influences of the food environment on dietary behaviors.

Context and Time Matter: Effects of Emotion and Motivation on Episodic Memory Overtime

PubMed Central

Sun, Qing; Gu, Simeng

2018-01-01

Previous studies have shown that compared with neutral cues, stimuli with positive and negative/stressful contexts or reward and punishment cues are remembered better. However, it is unclear whether the enhanced effect differs in emotion or motivation dimensions and the passage of time. We addressed these issues by manipulating different contextual cues for neutral words at different time intervals. In experiment 1, subjects were asked to learn words with picture contexts in positive, negative/stressful, and neutral valences and were tested by old/new word recognition and contextual judgment 10 min, 1 day, and 1 week later. In experiment 2, the reward and punishment motivations were manipulated by monetary cues during learning. Word recognition and contextual judgment were assessed 10 min, 1 day, 1 week, and 1 month after the study. Compared with negative and punishment conditions, the words in positive and reward contexts were recognized better at shorter intervals, which was associated with recollection process. In contrast, the words in negative and punishment contexts were recognized better at longer intervals, which was mainly associated with familiarity process. These results clarified how different dimensions of emotional and motivational contexts influence memory at short and long intervals and highlighted the role of contextual features in memory formation and consolidation.

Security Enhancement Mechanism Based on Contextual Authentication and Role Analysis for 2G-RFID Systems

PubMed Central

Tang, Wan; Chen, Min; Ni, Jin; Yang, Ximin

2011-01-01

The traditional Radio Frequency Identification (RFID) system, in which the information maintained in tags is passive and static, has no intelligent decision-making ability to suit application and environment dynamics. The Second-Generation RFID (2G-RFID) system, referred as 2G-RFID-sys, is an evolution of the traditional RFID system to ensure better quality of service in future networks. Due to the openness of the active mobile codes in the 2G-RFID system, the realization of conveying intelligence brings a critical issue: how can we make sure the backend system will interpret and execute mobile codes in the right way without misuse so as to avoid malicious attacks? To address this issue, this paper expands the concept of Role-Based Access Control (RBAC) by introducing context-aware computing, and then designs a secure middleware for backend systems, named Two-Level Security Enhancement Mechanism or 2L-SEM, in order to ensure the usability and validity of the mobile code through contextual authentication and role analysis. According to the given contextual restrictions, 2L-SEM can filtrate the illegal and invalid mobile codes contained in tags. Finally, a reference architecture and its typical application are given to illustrate the implementation of 2L-SEM in a 2G-RFID system, along with the simulation results to evaluate how the proposed mechanism can guarantee secure execution of mobile codes for the system.

Huss, R; Green, A; Sudarshan, H; Karpagam, Ss; Ramani, Kv; Tomson, G; Gerein, N

2011-11-01

Strengthening good governance and preventing corruption in health care are universal challenges. The Karnataka Lokayukta (KLA), a public complaints agency in Karnataka state (India), was created in 1986 but played a prominent role controlling systemic corruption only after a change of leadership in 2001 with a new Lokayukta (ombudsman) and Vigilance Director for Health (VDH). This case study of the KLA (2001-06) analysed the:Scope and level of poor governance in the health sector; KLA objectives and its strategy; Factors which affected public health sector governance and the operation of the KLA. We used a participatory and opportunistic evaluation design, examined documents about KLA activities, conducted three site visits, two key informant and 44 semi-structured interviews and used a force field model to analyse the governance findings. The Lokayukta and his VDH were both proactive and economically independent with an extended social network, technical expertise in both jurisdiction and health care, and were widely perceived to be acting for the common good. They mobilized media and the public about governance issues which were affected by factors at the individual, organizational and societal levels. Their investigations revealed systemic corruption within the public health sector at all levels as well as in public/private collaborations and the political and justice systems. However, wider contextual issues limited their effectiveness in intervening. The departure of the Lokayukta, upon completing his term, was due to a lack of continued political support for controlling corruption. Governance in the health sector is affected by positive and negative forces. A key positive factor was the combined social, cultural and symbolic capital of the two leaders which empowered them to challenge corrupt behaviour and promote good governance. Although change was possible, it was precarious and requires continuous political support to be sustained.

Exploring the value of mixed methods within the At Home/Chez Soi housing first project: a strategy to evaluate the implementation of a complex population health intervention for people with mental illness who have been homeless.

PubMed

Macnaughton, Eric L; Goering, Paula N; Nelson, Geoffrey B

2012-05-02

This paper is a methodological case study that describes the At Home/Chez Soi (Housing First) Initiative's mixed-methods strategy for implementation evaluation and discusses the value of these methods in evaluating the implementation of such complex population health interventions. The Housing First (HF) model is being implemented in five cities: Vancouver, Winnipeg, Toronto, Montréal and Moncton. At Home/Chez Soi is an intervention trial that aims to address the issue of homelessness in people with mental health issues. The HF model emphasizes choices, hopefulness and connecting people with resources that make a difference to their quality of life. A component of HF is supported housing, which provides a rent subsidy and rapid access to housing of choice in private apartments; a second component is support. Quantitative and qualitative methods were used to evaluate HF implementation. The findings of this case study illustrate how the critical ingredients of complex interventions, such as HF, can be adapted to different contexts while implementation fidelity is maintained at a theoretical level. The findings also illustrate how the project's mixed methods approach helped to facilitate the adaptation process. Another value of this approach is that it identifies systemic and organizational factors (e.g., housing supply, discrimination, housing procurement strategy) that affect implementation of key elements of HF. In general, the approach provides information about both whether and how key aspects of the intervention are implemented effectively across different settings. It thus provides implementation data that are rigorous, contextually relevant and practical.

2017-09-07

To identify contextual factors at different organisational levels to guide the implementation of an assistive living technology intervention in Norwegian primary home care. A single embedded case study design was carried out in an urban municipality in Western Norway to get an overview of key contextual factors from the municipality's perspective. The data collection was based on a triangulation of methods involving document analysis, semi-structured individual interviews and focus group interviews to get a broad insight when preparing for an intervention. Data were collected on three levels of the healthcare system: (1) national policy documents and regulations (macro), (2) five individual interviews with senior managers and municipal strategy documents (meso) and (3) two focus group interviews with nurses and nurse managers in direct patient care (micro). The Model for Understanding Success in Quality framework was used as a guide in the data analysis. The main contextual factors identified were external motivators and project sponsorship (macro level); leadership, workforce focus and maturity (meso level);and motivation to change and maturity (micro level). Strategies developed in policy documents affected upper management in the municipality, but healthcare personnel at the micro level were not so familiar with strategies and emphasis on assistive living technologies. Healthcare personnel in our study were motivated to use technological solutions, but lack of data infrastructure and resource availability hindered this. Aligning interests across multiple stakeholders remain a challenge when planning for an assistive living technology intervention in primary care. In the studied municipality, integration of technological solutions into healthcare services was more a vision than a reality because of a low level of organisational readiness. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

PURPOSE An isolated focus on 1 disease at a time is insufficient to generate the scientific evidence needed to improve the health of persons living with more than 1 chronic condition. This article explores how to bring context into research efforts to improve the health of persons living with multiple chronic conditions (MCC). METHODS Forty-five experts, including persons with MCC, family and friend caregivers, researchers, policy makers, funders, and clinicians met to critically consider 4 aspects of incorporating context into research on MCC: key contextual factors, needed research, essential research methods for understanding important contextual factors, and necessary partnerships for catalyzing collaborative action in conducting and applying research. RESULTS Key contextual factors involve complementary perspectives across multiple levels: public policy, community, health care systems, family, and person, as well as the cellular and molecular levels where most research currently is focused. Needed research involves moving from a disease focus toward a person-driven, goal-directed research agenda. Relevant research methods are participatory, flexible, multilevel, quantitative and qualitative, conducive to longitudinal dynamic measurement from diverse data sources, sufficiently detailed to consider what works for whom in which situation, and generative of ongoing communities of learning, living and practice. Important partnerships for collaborative action include cooperation among members of the research enterprise, health care providers, community-based support, persons with MCC and their family and friend caregivers, policy makers, and payers, including government, public health, philanthropic organizations, and the business community. CONCLUSION Consistent attention to contextual factors is needed to enhance health research for persons with MCC. Rigorous, integrated, participatory, multimethod approaches to generate new knowledge and diverse partnerships can be used to increase the relevance of research to make health care more sustainable, safe, equitable and effective, to reduce suffering, and to improve quality of life.

Forensic case formulation, of increasing interest to practitioners and researchers raises many ethical, theoretical and practical issues for them. Systemic, contextual and individual factors which need to be considered include the multitude of staff often involved with any one individual, the pressure to 'get it right' because of the range of risk implications that are associated with individuals within forensic mental health settings, and individual parameters, for example reluctance to be engaged with services.

Community engagement has contributed to disease control and elimination in many countries. Community engagement in malaria elimination (ME) on Aneityum Island has been sustained since its introduction in the early 1990s. Capacity developed within this population has led to a health empowered community response. Health Empowerment Theory (HET) can account for the innovative community actions and capacity development efforts taken to realize and sustain meaningful changes in well-being. This study used the HET framework to investigate participant perceptions of ME efforts on the island focusing on two HET elements, personal and social-contextual resources. The purpose of this study was to explore the role of empowerment as a critical element of community engagement. Six focus group discussions, ten key informant interviews and 17 in-depth interviews were conducted in July 2012 on Aneityum. Both deductive and inductive approaches to qualitative content analysis were used to identify themes, which were condensed, coded and classified based on the HET elements above. Awareness and use of personal and social-contextual resources played an important role in ME efforts. Most participants shared their knowledge to prevent malaria reintroduction. Many participants reported their skills needed for behavioral maintenance, problem-solving or leadership. Participants who perceived a threat took preventive actions even in the dry season. Community leaders focused on second generation capacity development. A local health coalition provided ME services. Members of networks were sources of information and assistance. Face-to-face was the preferred method of communication. Barriers to engagement (e.g., financial difficulties, health literacy issues and underdeveloped infrastructure) were minimized through active collaboration and mutual assistance. In the community engagement continuum, health empowerment develops incrementally overtime as people gain their knowledge and skills, form coalitions and develop collaborative networks (social capital) to make decisions and take action for change. Community engagement, which facilitates local personal and social-contextual resource development, has potential for ME and multilevel empowerment through community-based capacity development processes. These self-empowered communities have written and will continue to write a 'prescription' for sustaining high levels of engagement.

We advocate a more contextual perspective in giftedness research. In our view, doing so opens up three particularly interesting research areas, which we refer to as the participation issue, the effectiveness issue, and the interaction issue. To illustrate their utility, we examined characteristics of females participating in German high achiever-track secondary education who had applied for participation in a 1-year extracurricular e-mentoring program in science, technology, engineering, and mathematics (STEM) (n = 1237). Their characteristics were compared with male and female random-sample control groups. We assessed the effectiveness of the mentoring program by comparing the developmental trajectories of program participants with those of three control groups: applicants who were randomly chosen for later participation (waiting-list control group) and a female and a male control group. Finally, we examined whether differences in program effectiveness could be partially explained by characteristics of the interaction with the domain. Program applicants possessed more advantageous individual characteristics but, unexpectedly, less advantageous home and school environments than female and male members of the control groups. Program participation affected positive changes in certainty about career goals (independent of STEM) and in the number of STEM activities. The amount of STEM communication partially explained differences in program effectiveness. © 2016 New York Academy of Sciences.

A sequential model to link contextual risk, perception and public support for flood adaptation policy.

Shao, Wanyun; Xian, Siyuan; Lin, Ning; Small, Mitchell J

2017-10-01

The economic damage from coastal flooding has dramatically increased over the past several decades, owing to rapid development in shoreline areas and possible effects of climate change. To respond to these trends, it is imperative for policy makers to understand individuals' support for flood adaptation policy. Using original survey data for all coastal counties of the United States Gulf Coast merged with contextual data on flood risk, this study investigates coastal residents' support for two adaptation policy measures: incentives for relocation and funding for educational programs on emergency planning and evacuation. Specifically, this study explores the interactive relationships among contextual flood risks, perceived flood risks and policy support for flood adaptation, with the effects of social-demographic variables being controlled. Age, gender, race and partisanship are found to significantly affect individuals' policy support for both adaptation measures. The contextual flooding risks, indicated by distance from the coast, maximum wind speed and peak height of storm surge associated with the last hurricane landfall, and percentage of high-risk flood zone per county, are shown to impact one's perceptions of risk, which in turn influence one's support for both policy measures. The key finding -risk perception mediates the impact of contextual risk conditions on public support for flood management policies - highlights the need to ensure that the public is well informed by the latest scientific, engineering and economic knowledge. To achieve this, more information on current and future flood risks and options available for mitigation as well as risk communication tools are needed. Copyright © 2017 Elsevier Ltd.

Contextual and interdependent causes of climate change adaptation barriers for water management: responses from regional and local institutions in Himachal Pradesh, India

NASA Astrophysics Data System (ADS)

Azhoni, Adani; Holman, Ian; Jude, Simon

2016-04-01

Research on adaptation barriers is gaining increasing prominence as the need for climate change adaptation becomes evident. This research seeks to identify and understand the reasons for key barriers preventing water institutions in the mountainous Himalayan state of Himachal Pradesh in northern India from adapting to climate change. Semi-structured interviews were carried out in January & February 2015 with representatives from twenty-seven key governmental, academic, NGO and commercial institutions in the State, with responsibilities spanning from municipal water supply to irrigation and hydropower generation in addition to environmental conservation. Empirical analysis of the transcripts found that inadequate knowledge capacity, poor implementation of policies, inadequate resources, normative work culture, weak governance, unavailability and inaccessibility of data & information and limited inter-institutional networks are key barriers for adaptation. Although these generic barriers are similar to those reported elsewhere in literature, they are identified as having locally-contextual root causes. For example, the inadequate resources are identified to be occurring as a consequence of the fragmentation of resources allocation among others. This is due to competing developmental priorities and the desire of the political leadership to please the maximum number of electors rather than the more-usual inadequate budgetary allocation and climate scepticism. The identified individual barriers are found to be highly inter-dependent and closely intertwined which enables the identification of leverage points of interventions that can maximise removal of barriers. For example, breaking down key barriers for data and information accessibility will have to involve normative attitudinal change, through sensitisation of the larger picture of the role of accurate and accessible data; changes in working style involving moving from paper-based data management to digital; and institutional and structural changes through legislation or formal inter-institutional agreements for increasing data accessibility and sharing. This presentation will demonstrate how adaptation barriers in Himachal Pradesh are contextually interconnected by a range of cultural, systemic, geographical and political underlying causes and how this understanding can be used to increase the adaptive capacity of this climatically sensitive region.

Hudon, Catherine; Chouinard, Maud-Christine; Lambert, Mireille; Diadiou, Fatoumata; Bouliane, Danielle; Beaudin, Jérémie

2017-01-01

Objective The aim of this paper was to identify the key factors of case management (CM) interventions among frequent users of healthcare services found in empirical studies of effectiveness. Design Thematic analysis review of CM studies. Methods We built on a previously published review that aimed to report the effectiveness of CM interventions for frequent users of healthcare services, using the Medline, Scopus and CINAHL databases covering the January 2004–December 2015 period, then updated to July 2017, with the keywords ‘CM’ and ‘frequent use’. We extracted factors of successful (n=7) and unsuccessful (n=6) CM interventions and conducted a mixed thematic analysis to synthesise findings. Chaudoir’s implementation of health innovations framework was used to organise results into four broad levels of factors: (1) environmental/organisational level, (2) practitioner level, (3) patient level and (4) programme level. Results Access to, and close partnerships with, healthcare providers and community services resources were key factors of successful CM interventions that should target patients with the greatest needs and promote frequent contacts with the healthcare team. The selection and training of the case manager was also an important factor to foster patient engagement in CM. Coordination of care, self-management support and assistance with care navigation were key CM activities. The main issues reported by unsuccessful CM interventions were problems with case finding or lack of care integration. Conclusions CM interventions for frequent users of healthcare services should ensure adequate case finding processes, rigorous selection and training of the case manager, sufficient intensity of the intervention, as well as good care integration among all partners. Other studies could further evaluate the influence of contextual factors on intervention impacts. PMID:29061623

The challenges of military medical education and training for physicians and nurses in the Nordic countries - an interview study.

PubMed

Sonesson, Linda; Boffard, Kenneth; Lundberg, Lars; Rydmark, Martin; Karlgren, Klas

2017-04-11

Development and use of e-learning has not taken place to the same extent in military medicine in the Nordic countries. The aim was to explore the similarities and differences in education and training in military medicine for health professionals in the Nordic countries, and more specifically to identify the specific challenges regarding education and training of military medicine, and how e-learning is used at present and the opportunities for the future. Key educators within military medicine in the Nordic countries, as approved by the respective Surgeons General, were interviewed and the interviews were analyzed using content analysis. The data showed that all Nordic countries cooperate in the field of military medical training to some extent. The models of recruitment and employment of health professionals differed as well as the degree of political support. These differences affected the ability for health professionals to gain actual experience from the military environment. To improve the quality of medical education and training, attempts were made to recruit physicians. The recruitment of physicians was considered a challenge which had resulted in disruptions of courses, training programs and maintenance of accreditation. The Nordic countries were described as having commonalities in the military medical systems and common needs for international collaboration within training, but differing in the range of education and training. Gaps were identified in methods for transferring outcomes from education into practice, as well as regarding evaluation and feedback of outcomes to military medicine. The educational tradition was described as oriented towards practical skills training without requirements on pedagogical education of educators. The results confirmed previous studies showing that e-learning was underutilized. Contextual understanding and experience of healthcare were seen as crucial factors for successful e-learning development. Extended Nordic cooperation on military medical education and training are needed because of the limited volumes of advanced trauma cases. A key issue to the success of e-learning and blended learning is combining educational competence with contextual understanding into a strategy, of how to use digital educational methods.

Artifact-based reflective interviews for identifying pragmatic epistemological resources

NASA Astrophysics Data System (ADS)

Shubert, Christopher Walden

Physics Education Research studies the science of teaching and learning physics. The process of student learning is complex, and the factors that affect it are numerous. Describing students' understanding of physics knowledge and reasoning is the basis for much productive research; however, such research fails to account for certain types of student learning difficulties. In this dissertation, I explore one source of student difficulty: personal epistemology, students' ideas about knowledge and knowing. Epistemology traditionally answers three questions: What is knowledge? How is knowledge created? And, how do we know what we know? An individual's responses to these questions can affect learning in terms of how they approach tasks involving the construction and application of knowledge. The key issue addressed in this dissertation is the effect of methodological choices on the validity and reliability of claims concerning personal epistemology. My central concern is contextual validity, how what is said about one's epistemology is not identical to how one behaves epistemologically. In response to these issues, I present here a new methodology for research on student epistemology: video artifact-based reflective interview protocols. These protocols begin with video taping students in their natural classroom activities, and then asking the participants epistemological questions immediately after watching selected scenes from their activity, contextually anchoring them in their actual learning experience. The data from these interviews is viewed in the framework of Epistemological Resource Theory, a framework of small bits of knowledge whose coordination in a given context is used to describe personal epistemology. I claim that the privileged data from these interviews allows detailed epistemological resources to be identified, and that these resources can provide greater insight into how student epistemologies are applied in learning activities. This research, situated within an algebra-based physics for life scientists course reform project, focuses on student work in Modeling Informed Instruction (MII) laboratory activities, which are an adaptation of Modeling Instruction. The development of these activities is based on the epistemological foundations of Modeling Instruction, and these foundations are used to describe a potential assessment for the epistemological effectiveness of a curriculum.

Contextualized analysis of a needs assessment using the Theoretical Domains Framework: a case example in endocrinology

PubMed Central

2014-01-01

Background The Theoretical Domains Framework (TDF) is a set of 14 domains of behavior change that provide a framework for the critical issues and factors influencing optimal knowledge translation. Considering that a previous study has identified optimal knowledge translation techniques for each TDF domain, it was hypothesized that the TDF could be used to contextualize and interpret findings from a behavioral and educational needs assessment. To illustrate this hypothesis, findings and recommendations drawn from a 2012 national behavioral and educational needs assessment conducted with healthcare providers who treat and manage Growth and Growth Hormone Disorders, will be discussed using the TDF. Methods This needs assessment utilized a mixed-methods research approach that included a combination of: [a] data sources (Endocrinologists (n:120), Pediatric Endocrinologists (n:53), Pediatricians (n:52)), [b] data collection methods (focus groups, interviews, online survey), [c] analysis methodologies (qualitative - analyzed through thematic analysis, quantitative - analyzed using frequencies, cross-tabulations, and gap analysis).

The Theoretical Domains Framework (TDF) is a set of 14 domains of behavior change that provide a framework for the critical issues and factors influencing optimal knowledge translation. Considering that a previous study has identified optimal knowledge translation techniques for each TDF domain, it was hypothesized that the TDF could be used to contextualize and interpret findings from a behavioral and educational needs assessment. To illustrate this hypothesis, findings and recommendations drawn from a 2012 national behavioral and educational needs assessment conducted with healthcare providers who treat and manage Growth and Growth Hormone Disorders, will be discussed using the TDF. This needs assessment utilized a mixed-methods research approach that included a combination of: [a] data sources (Endocrinologists (n:120), Pediatric Endocrinologists (n:53), Pediatricians (n:52)), [b] data collection methods (focus groups, interviews, online survey), [c] analysis methodologies (qualitative - analyzed through thematic analysis, quantitative - analyzed using frequencies, cross-tabulations, and gap analysis).

Mayor advancements have been achieved in research on the cultural adaptation of prevention and treatment interventions that are conducted with diverse ethnocultural groups. This commentary addresses conceptual, ethical, contextual, and methodological issues related to cultural adaptations. The articles in this special issue represent a major contribution to the study of cultural adaptations in prevention science. We frame our analysis of fidelity to core intervention components using a conceptual approach that examines (a) the propositional model (theory of change), (b) the procedural model (theory of action, methods), and (c) the philosophical assumptions that undergird these models. Regarding ethics, we caution against imposing the norms, values, and world views of the Western dominant society onto vulnerable populations such as ethnocultural groups. Given that the assumption of universality in behavioral science has been questioned, and as randomized clinical trials (RCTs) seldom examine the ecological validity of evidence-based interventions and treatments (EBI/T), imposing such interventions onto ethnocultural groups is problematic since these interventions contain values, norms, beliefs, and worldviews that may be contrary to those held by many ethnocultural groups. Regarding methods, several innovative designs are discussed that serve as alternatives to the RCT and represent an important contribution to prevention science. Also, we discuss guidelines for conducting cultural adaptations. Finally, the articles in this special issue make a major contribution to the growing field of cultural adaptation of preventive interventions with ethnocultural groups and majority-world populations.

Improving quality of care through routine, successful implementation of evidence-based practice at the bedside: an organizational case study protocol using the Pettigrew and Whipp model of strategic change

PubMed Central

2007-01-01

Background Evidence-based practice (EBP) is an expected approach to improving the quality of patient care and service delivery in health care systems internationally that is yet to be realized. Given the current evidence-practice gap, numerous authors describe barriers to achieving EBP. One recurrently identified barrier is the setting or context of practice, which is likewise cited as a potential part of the solution to the gap. The purpose of this study is to identify key contextual elements and related strategic processes in organizations that find and use evidence at multiple levels, in an ongoing, integrated fashion, in contrast to those that do not. Methods The core theoretical framework for this multi-method explanatory case study is Pettigrew and Whipp's Content, Context, and Process model of strategic change. This framework focuses data collection on three entities: the Why of strategic change, the What of strategic change, and the How of strategic change, in this case related to implementation and normalization of EBP. The data collection plan, designed to capture relevant organizational context and related outcomes, focuses on eight interrelated factors said to characterize a receptive context. Selective, purposive sampling will provide contrasting results between two cases (departments of nursing) and three embedded units in each. Data collection methods will include quantitative tools (e.g., regarding culture) and qualitative approaches including focus groups, interviews, and documents review (e.g., regarding integration and “success”) relevant to the EBP initiative. Discussion This study should provide information regarding contextual elements and related strategic processes key to successful implementation and sustainability of EBP, specifically in terms of a pervasive pattern in an acute care hospital-based health care setting. Additionally, this study will identify key contextual elements that differentiate successful implementation and sustainability of EBP efforts, both within varying levels of a hospital-based clinical setting and across similar hospital settings interested in EBP.

Despite a national focus on post-acute care brought about by recent payment reforms, relatively little is known about how hospitalized older adults and their caregivers decide whether to go to a skilled nursing facility (SNF) after hospitalization. We sought to understand to what extent hospitalized older adults and their caregivers are empowered to make a high-quality decision about utilizing an SNF for post-acute care and what contextual or process elements led to satisfaction with the outcome of their decision once in SNF. Qualitative inquiry using the Ottawa Decision Support Framework (ODSF), a conceptual framework that describes key components of high-quality decision-making. Thirty-two previously community-dwelling older adults (≥ 65 years old) and 22 caregivers interviewed at three different hospitals and three skilled nursing facilities. We used key components of the ODSF to identify elements of context and process that affected decision-making and to what extent the outcome was characteristic of a high-quality decision: informed, values based, and not associated with regret or blame. The most important contextual themes were the presence of active medical conditions in the hospital that made decision-making difficult, prior experiences with hospital readmission or SNF, relative level of caregiver support, and pressure to make a decision quickly for which participants felt unprepared. Patients described playing a passive role in the decision-making process and largely relying on recommendations from the medical team. Patients commonly expressed resignation and a perceived lack of choice or autonomy, leading to dissatisfaction with the outcome. Understanding and intervening to improve the quality of decision-making regarding post-acute care supports is essential for improving outcomes of hospitalized older adults. Our results suggest that simply providing information is not sufficient; rather, incorporating key contextual factors and improving the decision-making process for both patients and clinicians are also essential.

Reality, Contextuality, and Probability in Quantum Theory and Beyond

NASA Astrophysics Data System (ADS)

Plotnitsky, Arkady

This chapter explores the relationships among reality, contextuality, and probability, especially in quantum theory and, brie y and by extension, in other fields where these concepts, in their quantum-like versions, may play key roles. The chapter contends, following Derrida's argument, that while no meaning or event could be determined apart from its context, no context ultimately permits saturation, that is, could ever be determined with certainty. Any such determination is ultimately provisional. However, because of its mathematical-experimental character, physics allows one, in classical physics and relativity, to disregard the role of the context of observation in describing the physical systems considered, and in quantum mechanics, where the context of observation cannot be so disregarded, to determine such a context sufficiently. While, however, classical physics or relativity and quantum mechanics can do so sufficiently for their disciplinary functioning and practice, they cannot do so entirely. Moreover, a given concept of this functioning, especially as concerns what is considered its proper functioning, still depends on a broader contextual field that defies saturation or guaranteed determination.

To overcome the weakness of the contextual interference (CI) effect within applied settings, Brady, 2008 recommended that the amount of interference be manipulated. This study investigated the effect of five practice schedules on the learning of three field hockey skills. Fifty-five pre-university students performed a total of 90 trials for each skill under blocked, mixed or random practice orders. Results showed a significant time effect with all five practice conditions leading to improvements in acquisition and learning of the skills. No significant differences were found between the groups. The findings of the present study did not support the CI effect and suggest that either blocked, mixed, or random practice schedules can be used effectively when structuring practice for beginners. Key pointsThe contextual interference effect did not surface when using sport skills.There appears to be no difference between blocked and random practice schedules in the learning of field hockey skills.Low (blocked), moderate (mixed) or high (random) interference practice schedules can be used effectively when conducting a multiple skill practice session for beginners.

This issue of the Health Care Financing Review focuses on issues and advances in measuring and improving the quality of care, particularly for Medicare and Medicaid beneficiaries. Discussions of quality-related topics are especially timely, given the growing and widespread interest in improving quality in the organization, financing, and delivery of health care services. This article has several purposes. The first is to provide a brief description of some of the causes underlying the growth of the health care quality movement; the second is to provide a contextual framework for discussion of some of the overarching themes that emerge in this issue. These themes include examining conceptual issues, developing quality measures for specific sites and populations, and creating or adapting data sets for quality-measurement purposes. PMID:10151882

Retaining Participants in Outpatient and Community-Based Health Studies: Researchers and Participants in Their Own Words.

PubMed

Odierna, Donna H; Bero, Lisa A

Loss to follow-up can introduce bias into research, making it difficult to develop inclusive evidence-based health policies and practice guidelines. We aimed to deepen understanding of reasons why participants leave or remain in longitudinal health studies. We interviewed 59 researchers and current and former research participants in six focus groups ( n = 55) or interviews ( n = 4) at three study centers in a large academic research institution. We used minimally structured interview guides and inductive thematic analysis to explore participant-level, study-level, and contextual participation barriers and facilitators. Four main themes emerged: transportation, incentives and motivation, caregiver concerns, and the social and physical environment. Themes shared crosscutting issues involving funding, flexibility, and relationships between researchers and research participants. Study-level and contextual factors appear to interact with participant characteristics, particularly socioeconomic status and disease severity to affect participant retention. Participants' characteristics do not seem to be the main cause of study dropout. Researchers and funders might be able to address contextual and study factors in ways that reduce barriers to participation.

Abstract Background: Self-help strategies and various contextual factors support recovery. However, more in-depth knowledge is needed about how self-help strategies and supportive environments facilitate the recovery process. Aims: To explore what individuals who have recently been referred to a specialist Community Mental Health Center experience as helpful and what they do to help themselves. Method: Ten service users participated in in-depth interviews within a collaborative-reflexive framework. A hermeneutic-phenomenological approach was used. Results: Participants described a variety of helpful strategies and environmental supports. Four relevant main themes were identified: helpful activities, helpful people and places, self-instruction and learning about mental problems and medication and self-medication. Conclusions: The process of recovery is initiated before people become users of mental health services. This study confirms that recovery takes place within the person’s daily life context and involves the interplay of contextual factors, such as family, friends, good places, work and other meaningful activities. The coping strategies reported may represent an important focus for attention and clinical intervention. PMID:26484831

Determinants of health information-seeking behavior: implications for post-treatment cancer patients.

PubMed

Jung, Minsoo

2014-01-01

Health information-seeking behavior (HISB) is active need-fulfillment behavior whereby health information is obtained from diverse sources, such as the media, and has emerged as an important issue within the transforming medical environment and the rise of medical consumers. However, little is known about the factors that affect HISB and its associations, and the health outcome of HISB. The aim of this study was to examine individual and social contextual factors associated with HISB and to systematically review their effects on health status among post- treatment cancer patients. Individual determinants of HISB included demographic factors, psychosocial factors, perceived efficacy and norms, and health beliefs. Contextual determinants of HISB encompassed community characteristics, neighborhood social capital, and media advocacy. Improving through factors on these two levels, HISB raised individuals' self-care management skills and medical treatment compliance, and enhanced shared decision-making and medical treatment satisfaction. Moreover, because HISB can differ according to individuals' social contextual conditions, it can give rise to communication inequalities. Because these can ultimately lead to health disparities between groups, social interest in HISB and balanced HISB promotion strategies are necessary.

Test anxiety: a cross-cultural perspective.

The present paper examines test anxiety from a cross-cultural perspective with specific reference to the Indian and American cultures. The construct of test anxiety has been examined in many cultures all over the world. In this review, the importance of understanding and incorporating contextual factors in cross-cultural research is emphasized. Moreover, some of the methodological issues related to investigating culture-behavior relationship are discussed. Specifically, the derived-etic approach for conducting cross-cultural research is espoused. Then, research findings from western, cross-cultural, and Indian studies on test anxiety are reviewed. Consistent with the individualistic orientation of the western society, much of the research in the western world has adopted a de-contextualized approach. Inasmuch as many of the cross-cultural and Indian studies on test anxiety have their roots in western research, they have ignored the cultural context as well. To address this void, contextual variables relevant to test anxiety in the Indian setting are examined and hypotheses regarding the nature of test anxiety in Indian children are proposed. Finally, a research agenda is presented to examine these hypotheses using a derived-etic approach.

Exploiting scene context and object-object co-occurrence is critical in guiding eye movements and facilitating visual search, yet the mediating neural mechanisms are unknown. We used functional magnetic resonance imaging while observers searched for target objects in scenes and used multivariate pattern analyses (MVPA) to show that the lateral occipital complex (LOC) can predict the coarse spatial location of observers' expectations about the likely location of 213 different targets absent from the scenes. In addition, we found weaker but significant representations of context location in an area related to the orienting of attention (intraparietal sulcus, IPS) as well as a region related to scene processing (retrosplenial cortex, RSC). Importantly, the degree of agreement among 100 independent raters about the likely location to contain a target object in a scene correlated with LOC's ability to predict the contextual location while weaker but significant effects were found in IPS, RSC, the human motion area, and early visual areas (V1, V3v). When contextual information was made irrelevant to observers' behavioral task, the MVPA analysis of LOC and the other areas' activity ceased to predict the location of context. Thus, our findings suggest that the likely locations of targets in scenes are represented in various visual areas with LOC playing a key role in contextual guidance during visual search of objects in real scenes.

Context: The mixed results of success among QI initiatives may be due to differences in the context of these initiatives. Methods: The business and health care literature was systematically reviewed to identify contextual factors that might influence QI success; to categorize, summarize, and synthesize these factors; and to understand the current stage of development of this research field. Findings: Forty-seven articles were included in the final review. Consistent with current theories of implementation and organization change, leadership from top management, organizational culture, data infrastructure and information systems, and years involved in QI were suggested as important to QI success. Other potentially important factors identified in this review included: physician involvement in QI, microsystem motivation to change, resources for QI, and QI team leadership. Key limitations in the existing literature were the lack of a practical conceptual model, the lack of clear definitions of contextual factors, and the lack of well-specified measures. Conclusions: Several contextual factors were shown to be important to QI success, although the current body of literature lacks adequate definitions and is characterized by considerable variability in how contextual factors are measured across studies. Future research should focus on identifying and developing measures of context tied to a conceptual model that examines context across all levels of the health care system and explores the relationships among various aspects of context.

Double Dissociation of Amygdala and Hippocampal Contributions to Trace and Delay Fear Conditioning

2011-01-01

A key finding in studies of the neurobiology of learning memory is that the amygdala is critically involved in Pavlovian fear conditioning. This is well established in delay-cued and contextual fear conditioning; however, surprisingly little is known of the role of the amygdala in trace conditioning. Trace fear conditioning, in which the CS and US are separated in time by a trace interval, requires the hippocampus and prefrontal cortex. It is possible that recruitment of cortical structures by trace conditioning alters the role of the amygdala compared to delay fear conditioning, where the CS and US overlap. To investigate this, we inactivated the amygdala of male C57BL/6 mice with GABA A agonist muscimol prior to 2-pairing trace or delay fear conditioning. Amygdala inactivation produced deficits in contextual and delay conditioning, but had no effect on trace conditioning. As controls, we demonstrate that dorsal hippocampal inactivation produced deficits in trace and contextual, but not delay fear conditioning. Further, pre- and post-training amygdala inactivation disrupted the contextual but the not cued component of trace conditioning, as did muscimol infusion prior to 1- or 4-pairing trace conditioning. These findings demonstrate that insertion of a temporal gap between the CS and US can generate amygdala-independent fear conditioning. We discuss the implications of this surprising finding for current models of the neural circuitry involved in fear conditioning. PMID:21283812

Toward a culturally sensitive conceptualization of resilience: Participatory research with war-affected communities in northern Uganda.

Resilience research with war-affected populations has long conceptualized resilience as the absence of psychopathology and operationalized it by use of standardized measures. However, literature on resilience increasingly highlights the importance of also including indicators of positively valued functioning as well as contextually sensitive indicators of resilience. This study used a participatory approach to examine the contextual conceptualization of youth resilience in the aftermath of war in northern Uganda, as defined by groups of stakeholders (youths, parents, elders, leaders, teachers) in four communities. The results identify 40 indicators covering a multiplicity of domains of functioning. The rationales behind these indicators were clustered into the broad themes: progress, self-reliance, social connectedness, morality, health, and comfort. The findings suggest that positively and negatively valued aspects of functioning are both key to conceptualizing resilience, and indicate the importance of including contextually distinguished indicators. The findings further point to the role of individual and collective processes in the construction of resilience, and to the need to take into account the contexts wherein resilience is conceptualized and observed. This study generated contextually sensitive indicators of young people's resilience, which can be used, complementary to existing measures of functioning, to provide a more comprehensive and culturally sensitive view of youths' resilience in the wake of war adversity. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

To describe and compare pressure ulcer prevalence in two county councils and concurrently explore Nurse Managers' perspective of contextual factors in a hospital organization. Despite good knowledge about risk factors and prevention of pressure ulcers, the prevalence of pressure ulcers remains high. Nurse Managers' have a key role in implementing evidence-based practice. The present study included five hospitals in two Swedish county councils: county council A (non-university setting) and county council B (university setting). A pressure ulcer prevalence study was conducted according to the methodology developed by the European Pressure Ulcer Advisory Panel. The Nurse Managers' answered a (27-item) questionnaire on contextual factors. County council B had significantly less pressure ulcers grade (2-4) (7.7%) than county council A (11.3%). The Nurse Managers' assessed only two out of the 27 general contextual items significantly differently. Some significant differences were observed in ward organization. In county council B, the Nurse Managers' seemed more aware of prevention strategies compared with Nurse Managers' in county council A. The Nurse Managers' should take more responsibility to develop the prerequisite for quality improvement in nursing. Nursing outcomes (e.g. pressure ulcers) should be incorporated into national quality registries for benchmarking and Nurse Managers' competence in evidence-based practice and research methodology increased. © 2010 The Authors.

Temporally and functionally dissociable retrieval processing operations revealed by event-related potentials.

PubMed

Cruse, Damian; Wilding, Edward L

2011-06-01

In a pair of recent studies, frontally distributed event-related potential (ERP) indices of two distinct post-retrieval processes were identified. It has been proposed that one of these processes operates over any kinds of task relevant information in service of task demands, while the other operates selectively over recovered contextual (episodic) information. The experiment described here was designed to test this account, by requiring retrieval of different kinds of contextual information to that required in previous relevant studies. Participants heard words spoken in either a male or female voice at study and ERPs were acquired at test where all words were presented visually. Half of the test words had been spoken at study. Participants first made an old/new judgment, distinguishing via key press between studied and unstudied words. For words judged 'old', participants indicated the voice in which the word had been spoken at study, and their confidence (high/low) in the voice judgment. There was evidence for only one of the two frontal old/new effects that had been identified in the previous studies. One possibility is that the ERP effect in previous studies that was tied specifically to recollection reflects processes operating over only some kinds of contextual information. An alternative is that the index reflects processes that are engaged primarily when there are few contextual features that distinguish between studied stimuli. Copyright © 2011 Elsevier Ltd.

Oberle, Eva

2018-02-01

The objective was to predict early adolescents' emotional well-being from personal and contextual assets in the classroom. Emotional well-being is a key indicator of health. Aligned with the positive youth development (PYD) framework, a supportive classroom environment and positive relationships with teachers and peers were contextual assets in the present study; positive self-concept was a personal asset. The sample was 406 grade 4 to 7 public elementary school students from diverse backgrounds (mean = 11.27 years; SD = 0.89; 50% female). Data were self-, teacher-, and peer-reported. Structural equation modeling (SEM) analyses were used to evaluate model fit and identify significant pathways. SEM indicated a good model fit. Overall, 68% of variability in early adolescents' emotional well-being was explained. Positive self-concept directly predicted emotional well-being. Supportive classroom environment predicted emotional well-being directly and indirectly through increases in positive social relationships and self-concept. Positive social relationships predicted well-being only indirectly through positive self-concept. Contextual and personal assets are central for early adolescents' emotional well-being. The interrelation among assets needs to be considered when understanding, and ultimately promoting students' emotional well-being. The present findings extend previous research and inform school-based intervention and prevention programming and teacher professional development. © 2018, American School Health Association.

The diurnal oscillation of MAP (mitogen-activated protein) kinase and adenylyl cyclase activities in the hippocampus depends on the suprachiasmatic nucleus.

Consolidation of hippocampus-dependent memory is dependent on activation of the cAMP/Erk/MAPK (mitogen-activated protein kinase) signal transduction pathway in the hippocampus. Recently, we discovered that adenylyl cyclase and MAPK activities undergo a circadian oscillation in the hippocampus and that inhibition of this oscillation impairs contextual memory. This suggests the interesting possibility that the persistence of hippocampus-dependent memory depends upon the reactivation of MAPK in the hippocampus during the circadian cycle. A key unanswered question is whether the circadian oscillation of this signaling pathway is intrinsic to the hippocampus or is driven by the master circadian clock in the suprachiasmatic nucleus (SCN). To address this question, we ablated the SCN of mice by electrolytic lesion and examined hippocampus-dependent memory as well as adenylyl cyclase and MAPK activities. Electrolytic lesion of the SCN 2 d after training for contextual fear memory reduced contextual memory measured 2 weeks after training, indicating that maintenance of contextual memory depends on the SCN. Spatial memory was also compromised in SCN-lesioned mice. Furthermore, the diurnal oscillation of adenylyl cyclase and MAPK activities in the hippocampus was destroyed by lesioning of the SCN. These data suggest that hippocampus-dependent long-term memory is dependent on the SCN-controlled oscillation of the adenylyl cyclase/MAPK pathway in the hippocampus.

A key unanswered question is whether the circadian oscillation of this signaling pathway is intrinsic to the hippocampus or is driven by the master circadian clock in the suprachiasmatic nucleus (SCN). To address this question, we ablated the SCN of mice by electrolytic lesion and examined hippocampus-dependent memory as well as adenylyl cyclase and MAPK activities. Electrolytic lesion of the SCN two days after training for contextual fear memory reduced contextual memory measured two weeks after training indicating that maintenance of contextual memory depends on the SCN. Spatial memory was also compromised in SCN-lesioned mice. Furthermore, the diurnal oscillation of adenylyl cyclase and MAPK activities in the hippocampus was destroyed by lesioning of the SCN. These data suggest that hippocampus-dependent long-term memory is dependent on the SCN-controlled oscillation of the adenylyl cyclase/MAPK pathway in the hippocampus. PMID:21775607

BACKGROUND Race differences in the receipt of invasive cardiac procedures are well-documented but the etiology remains poorly understood. OBJECTIVE We examined how social contextual variables were related to race differences in the likelihood of receiving cardiac catheterization in a sample of veterans who were recommended to undergo the procedure by a physician. DESIGN Prospective observational cohort study. PARTICIPANTS A subsample from a study examining race disparities in cardiac catheterization of 48 Black/African American and 189 White veterans who were recommended by a physician to undergo cardiac catheterization. MEASURES We assessed social contextual variables (e.g., knowing somebody who had the procedure, being encouraged by family or friends), clinical variables (e.g., hypertension, maximal medical therapy), and if participants received cardiac catheterization at any point during the study. KEY RESULTS Blacks/African Americans were less likely to undergo cardiac catheterization compared to Whites even after controlling for age, education, and clinical variables (OR = 0.31; 95% CI, 0.13, 0.75). After controlling for demographic and clinical variables, three social contextual variables were significantly related to increased likelihood of receiving catheterization: knowing someone who had undergone the procedure (OR = 3.14; 95% CI, 1.70, 8.74), social support (OR = 2.05; 95% CI, 1.17, 2.78), and being encouraged by family to have procedure (OR = 1.45; 95% CI, 1.08, 1.90). After adding the social contextual variables, race was no longer significantly related to the likelihood of receiving catheterization, thus suggesting that social context plays an important role in the relationship between race and cardiac catheterization. CONCLUSIONS Our results suggest that social contextual factors are related to the likelihood of receiving recommended care. In addition, accounting for these relationships attenuated the observed race disparities between Whites and Blacks/African Americans who were recommended to undergo cardiac catheterization by their physicians.

Source Memory Rehabilitation: A Review Toward Recommendations for Setting Up a Strategy Training Aimed at the "What, Where, and When" of Episodic Retrieval.

2016-01-01

Source memory is a core component of episodic recall as it allows for the reconstruction of contextual details characterizing the acquisition of episodic events. Unlike episodic memory, little is known about source memory rehabilitation. Our review addresses this issue by emphasizing several strategies as useful tools in source memory rehabilitation programs. Four main strategies are likely to improve source recall in amnesic patients-namely, (a) contextual cueing, (b) unitization, (c) errorless learning, and (d) executive function programs. The rationale behind our suggestion is that: (a) reinstating contextual cues during retrieval can serve as retrieval cues and enhance source memory; (b) unitization as an encoding process allows for the integration of several pieces of contextual information into a new single entity; (c) errorless learning may prevent patients from making errors during source learning; and (d) as source memory deteriorations have been classically attributed to executive dysfunction, the rehabilitation of the latter ability is likely to maintain the former ability. Besides these four strategies, our review suggests several additional rehabilitation techniques such as the vanishing cues and spaced retrieval methods. Another additional strategy is the use of electronic devices. By gathering these strategies, our review provides a helpful guideline for clinicians dealing with source memory impairments. Our review further highlights the lack of randomized and controlled studies in the field of source memory rehabilitation.

Contextually relevant resources in speech-language therapy and audiology in South Africa--are there any?

PubMed

Pascoe, Michelle; Norman, Vivienne

2011-10-01

In this editorial introduction we aim to explore the notion of contextually relevant resources. We argue that it is the responsibility of speech-language therapists (SLTs) and audiologists (As) working in South Africa to develop contextually relevant resources, and not to rely on the countries or cultures where the professions originated to do so. Language is often cited as the main barrier to contextually relevant resources: most SLTs and As are aware of the need for more resources in the local languages. However, the issue is not as straightforward as translating resources from English into other languages. The challenges related to culture, e.g. formal education and familiarity with the test situation, have to be considered, as well as the population on which norms were obtained and the nature of vocabulary or picture items. This paper introduces four original research papers that follow in this edition of the journal, and showcases them as examples of innovative development in our field. At the same time we call for the further development of assessment materials, intervention resources, and contributions to the evidence base in our context. We emphasise the importance of local knowledge to drive the development of these resources in innovative and perhaps unexpected ways, and suggest that all clinicians have an important role to play in this process.

Categorizing experience-based foraging plasticity in mites: age dependency, primacy effects and memory persistence

2018-01-01

Behavioural plasticity can be categorized into activational (also termed contextual) and developmental plasticity. Activational plasticity allows immediate contextual behavioural changes, whereas developmental plasticity is characterized by time-lagged changes based on memory of previous experiences (learning). Behavioural plasticity tends to decline with age but whether this holds true for both plasticity categories and the effects of first-in-life experiences is poorly understood. We tackled this issue by assessing the foraging plasticity of plant-inhabiting predatory mites, Amblyseius swirskii, on thrips and spider mites following age-dependent prey experience, i.e. after hatching or after reaching maturity. Juvenile and young adult predator females were alternately presented thrips and spider mites, for establishing 1st and 2nd prey-in-life experiences, and tested, as gravid females, for their foraging plasticity when offered both prey species. Prey experience by juvenile predators resulted in clear learning effects, which were evident in likelier and earlier attacks on familiar prey, and higher proportional inclusion of familiar prey in total diet. First prey-in-life experience by juvenile but not adult predators resulted in primacy effects regarding attack latency. Prey experience by adult predators resulted mainly in prey-unspecific physiological changes, with easy-to-grasp spider mites providing higher net energy gains than difficult-to-grasp thrips. Prey experience by juvenile, but not adult, predators was adaptive, which was evident in a negative correlation between attack latencies and egg production. Overall, our study provides key evidence that similar experiences by juvenile and adult predators, including first-in-life experiences, may be associated with different types of behavioural plasticity, i.e. developmental and activational plasticity.

2015-01-01

Bratman first proposed orthorexia nervosa in the late 1990s, defining it an obsession with eating healthy food to achieve, for instance, improved health. Today, in the Swedish media, excessive exercising plays a central role in relation to orthorexia. A few review articles on orthorexia have been conducted; however, these have not focused on aspects of food and eating, sport, exercise, or a societal perspective. The overall aim of this study was to provide an overview and synthesis of what philosophies of science approaches form the current academic framework of orthorexia. Key questions were: What aspects of food and eating are related to orthorexia? What role do exercise and sports play in relation to orthorexia? In what ways are orthorexia contextualized? Consequently, the concept of healthism was used to discuss and contextualize orthorexia. The method used was an integrative literature review; the material covered 19 empirical and theoretical articles published in peer-reviewed journals. This review demonstrates a multifaceted nature of orthorexia research; this field has been examined from four different philosophies of science approaches (i.e., empirical-atomistic, empirical-atomistic with elements of empirical-holistic, empirical-holistic, and rational-holistic) on individual, social, and societal levels. The majority of the articles followed an empirical-atomistic approach that focused on orthorexia as an individual issue, which was discussed using healthism. Our analysis indicates a need for (a) more empirical-holistic research that applies interpretive qualitative methods and uses a social perspective of health, e.g., healthism and (b) examining the role of sports and exercise in relation to orthorexia that takes the problematizing of "orthorexic behaviours" within the sports context into account.

INTRODUCTION In New Zealand, while the term 'Asians' in popular discourse means East and South-east Asian peoples, Statistics New Zealand's definition includes people of many nationalities from East, South and South-east Asia, all with quite different cultural norms, taboos and degrees of conservatism. In a context where 'Asian' youth data are typically presented in aggregate form, there are notable gaps in knowledge regarding the contextual determinants of health in this highly heterogeneous group. This qualitative study explored key stakeholder views on issues that would be most useful to explore on the health and wellbeing of Asian youth and processes that would foster engagement of Asian youth in health research. METHODS Interviews were conducted with six key stakeholders whose professional activities were largely focused on the wellbeing of Asian people. The general inductive approach was used to identify and analyse themes in the qualitative text data. FINDINGS Six broad themes were identified from the key stakeholder interviews framed as priority areas that need further exploration: cultural identity, integration and acculturation; barriers to help-seeking; aspects to consider when engaging Asian youth in research (youth voice, empowerment and participatory approach to research); parental influence and involvement in health research; confidentiality and anonymity; and capacity building and informing policy. CONCLUSION With stakeholders strongly advocating the engagement of Asian youth in the health research agenda this study highlights the importance of engaging youth alongside service providers to collaborate on research and co-design responsive primary health care services in a multicultural setting.

2016-05-01

Considerable overlap exists between post-occupancy research evaluating building design quality and the concept of 'social value', popularised by its recent application to issues of the public realm. To outline this potential research agenda, the paper reviews design quality research on buildings in relation to users and their social context where the term 'social context' refers to building user group dynamics, a combination of organisational cultures, management strategies, and social norms and practices. The review is conducted across five key building types, namely housing, workplaces, healthcare, education, and the retail/service sector. Research commonalities and gaps are identified in order to build a more comprehensive picture of the design quality literature and its handling of users in their social context. The key findings concerning each building type are presented visually. It is concluded that the design quality field comprises a patchwork of relatively isolated studies of various building types, with significant potential for theoretical and empirical development through interdisciplinary collaboration. Users tend to be conceived as anonymous and autonomous individuals with little analysis of user identity or interaction. Further, the contextual impact of user group dynamics on the relationship between building design and building user is rarely addressed in the literature. Producing a more nuanced understanding of users in situ is proposed as an important area for future design quality research.

Priority setting research has focused on the macro (national) and micro (bedside) level, leaving the meso (institutional, hospital) level relatively neglected. This is surprising given the key role that hospitals play in the delivery of healthcare services and the large proportion of health systems resources that they absorb. To explore the factors that impact upon priority setting at the hospital level, we conducted a thematic review of empirical studies. A systematic search of PubMed, EBSCOHOST, Econlit databases and Google scholar was supplemented by a search of key websites and a manual search of relevant papers’ reference lists. A total of 24 papers were identified from developed and developing countries. We applied a policy analysis framework to examine and synthesize the findings of the selected papers. Findings suggest that priority setting practice in hospitals was influenced by (1) contextual factors such as decision space, resource availability, financing arrangements, availability and use of information, organizational culture and leadership, (2) priority setting processes that depend on the type of priority setting activity, (3) content factors such as priority setting criteria and (4) actors, their interests and power relations. We observe that there is need for studies to examine these issues and the interplay between them in greater depth and propose a conceptual framework that might be useful in examining priority setting practices in hospitals.

Reflective practice groups for nurses: a consultation liaison psychiatry nursing initiative: part 1--The model.

PubMed

Dawber, Chris

2013-04-01

In the present study, we outline the evolution of a process-focused reflective practice group (RPG) model for nurses working in clinical settings. The groups were initiated at Redcliffe and Caboolture hospitals by the consultation liaison psychiatry nurse and author. An associated article provides an evaluation of these RPG. The literature review identifies the key themes and theories on which the model is based, and the article outlines the process and practicalities of facilitating RPG in critical care, midwifery, and oncology specialties over a 3-year period. The model proposes that the effectiveness and sustainability of RPG arises from adequate preparation and engagement with prospective participants. Group rules, based on principles of confidentially, supportiveness, and diversity, were collaboratively developed for each group. Facilitation utilized a group-as-a-whole approach to manage process and stimulate reflection. While the purpose of RPG was a reflection on interpersonal aspects of nursing, contextual workplace issues were frequently raised in groups. Acknowledgement and containment of such issues were necessary to maintain clinical focus. The literature highlights facilitator credibility and style as crucial factors in the overall success of RPG, and it is proposed that reflective practice as a process-focused model for groups succeeds when nurse facilitators are trained in group process and receive concurrent supervision. © 2012 The Author; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

2017-01-01

Ebola virus causes a severe haemorrhagic fever in humans with high case fatality and significant epidemic potential. The 2013–2016 outbreak in West Africa was unprecedented in scale, being larger than all previous outbreaks combined, with 28 646 reported cases and 11 323 reported deaths. It was also unique in its geographical distribution and multicountry spread. It is vital that the lessons learned from the world's largest Ebola outbreak are not lost. This article aims to provide a detailed description of the evolution of the outbreak. We contextualize this outbreak in relation to previous Ebola outbreaks and outline the theories regarding its origins and emergence. The outbreak is described by country, in chronological order, including epidemiological parameters and implementation of outbreak containment strategies. We then summarize the factors that led to rapid and extensive propagation, as well as highlight the key successes, failures and lessons learned from this outbreak and the response. This article is part of the themed issue ‘The 2013–2016 West African Ebola epidemic: data, decision-making and disease control’. PMID:28396469

Secrecy as embodied practice: beyond the confessional imperative.

PubMed

Hardon, Anita; Posel, Deborah

2012-01-01

This introduction to this special issue of Culture, Health & Sexuality aims to intervene critically in debates in public health about sexual rights and ways of de-stigmatising HIV/AIDS, in which silence and secrets are seen to undermine well-being and perpetuate stigma. It presents key insights from collaborative studies on HIV/AIDS and youth sexual health, arguing that advocates of disclosure and sexual rights need to think more contextually and tactically in promoting truth-telling. The authors aim to enhance current thinking on secrecy, which examines it primarily as a social practice, by emphasising the centrality of the body and the experience of embodiment in the making and unmaking of secrets. To understand secrecy as embodied practice requires understanding how it simultaneously involves the body as subject - as the basis from which we experience the world - and the body as object - that can be actively manipulated, silenced and 'done'. The authors show how tensions emerge when bodies reveal reproductive mishaps and describe how the dissonances are resolved through a variety of silencing practices. The paper ends by discussing the implications of these insights for sexual-health programmes.

A Nursing Informatics Research Agenda for 2008–18: Contextual Influences and Key Components

Bakken, Suzanne; Stone, Patricia W.; Larson, Elaine L.

2008-01-01

The context for nursing informatics research has changed significantly since the National Institute of Nursing Research-funded Nursing Informatics Research Agenda was published in 1993 and the Delphi study of nursing informatics research priorities reported a decade ago. The authors focus on three specific aspects of context - genomic health care, shifting research paradigms, and social (Web 2.0) technologies - that must be considered in formulating a nursing informatics research agenda. These influences are illustrated using the significant issue of healthcare associated infections (HAI). A nursing informatics research agenda for 2008–18 must expand users of interest to include interdisciplinary researchers; build upon the knowledge gained in nursing concept representation to address genomic and environmental data; guide the reengineering of nursing practice; harness new technologies to empower patients and their caregivers for collaborative knowledge development; develop user-configurable software approaches that support complex data visualization, analysis, and predictive modeling; facilitate the development of middle-range nursing informatics theories; and encourage innovative evaluation methodologies that attend to human-computer interface factors and organizational context.

Bish, Melanie; Kenny, Amanda; Nay, Rhonda

2013-09-01

This paper outlines the processes and results of a participatory action research study undertaken to identify issues that may impact on strategies to foster nurse leadership in rural hospitals. Five Directors of Nursing from rural regions of Victoria, Australia participated. The group activities involved discussion and analysis of previous research, a review of current literature and critical reflection of the leadership performance of their organization. The analysis identified five key themes; dispel the myths, adopt big-picture thinking, connect with colleagues, reflect on your own conduct, and create organizational buy-in. It is essential to have an awareness of contextual challenges, an understanding of the importance of your own conduct as a visible leader, and the need for effective communication to inform the development of strategies that may be used to foster nurse leadership in rural hospitals. The platform to discuss and critically analyze leadership saw a group consensus that affirmed the need for any approach to nursing leadership to be tailored to the individual healthcare organization. © 2013 Wiley Publishing Asia Pty Ltd.

Theory and knowledge translation: setting some coordinates.

PubMed

Rycroft-Malone, Jo

2007-01-01

In a healthcare context in which research evidence is not used routinely in practice, there have been increasingly loud calls for the use of theory from investigators working in the field of knowledge translation. Implementation researchers argue that theory should be used to guide the design of testable and practical intervention strategies, and thus, contribute to generalizable knowledge about implementation interventions. The purpose of this commentary is to critique model papers writing by a team of scholars who aimed to disentangle some of the relationships determining research utilization, by scrutinizing an existing conceptual framework that acknowledges, along with other factors, the importance of contextual factors in knowledge translation. These papers are used as a vehicle to explore theory application in knowledge translation research. As theory use and development is in its infancy, some key issues, including different ideological perspectives, factors for and against theory use, ensuring conceptual clarity, selecting coherent overarching frameworks, and choosing appropriately among theories, are considered. Finally, an agenda for theory-informed research is outlined, which highlights the need for scholarly, pluralistic, and collaborative activity if the state of knowledge translation science is to advance.

The social production of health: critical contributions from evolutionary, biological, and cultural anthropology.

PubMed

Levin, Betty Wolder; Browner, C H

2005-08-01

In 1946, the newly formed World Health Organization boldly sought to conceptualize "health" as wellbeing in the positive sense, "not merely the absence of disease or infirmity." Yet nearly six decades later, researchers are still principally concerned with pathology and its characteristics and consequences. This special issue is the result of an effort to broaden the focus. Anthropologists working from evolutionary, biological and sociocultural perspectives and in diverse geographic regions were asked to examine meanings associated with health and/or to identify social conditions and practices that have contributed to positive physiological and psychological states in particular cultures, times, or across time. Most notable, perhaps, was discovering how difficult it is for Western social scientists to move beyond pathology-based thinking; most authors represented here regard health primarily as the absence of disease. Still, these papers articulate and address questions key to understanding health in and of itself, including: How is health conceptualized? What kinds of social conditions lead to health? And, how do social inequalities affect health? This introduction critically discusses previous work on the subject to contextualize the original research papers offered here.

Substance abuse treatment in persons with HIV/AIDS: challenges in managing triple diagnosis.

PubMed

Durvasula, Ramani; Miller, Theodore R

2014-01-01

Clinical management of HIV must account for the "triple diagnosis" of HIV, psychiatric diagnosis, and substance use disorders and requires integrated treatment services that focus beyond just mitigation of substance use and psychiatric and medical symptoms but also address other health behaviors. Because clinical management of HIV/AIDS has shifted significantly with the advent of highly active antiretroviral therapies (HAART) in the mid 1990s, a literature review focusing on literature published since 2000, and using relevant key words was conducted using a wide range of literature search databases. This literature review was complemented by studies to expand on specific treatment modalities for which there was a dearth of literature addressing HIV infected cohorts and to provide discussion of issues around substance abuse treatment as an HIV prevention tool. Existing models of substance abuse treatment including cognitive behavioral therapy and motivational interviewing have proven to be useful for enhancing adherence and reducing substance use in outpatient populations, while methadone maintenance and directly observed treatment have been useful with specific subgroups of users. Contextualization of services heightens the likelihood of successful outcomes and relapse prevention.

Representin' in cyberspace: sexual scripts, self-definition, and hip hop culture in Black American adolescent girls' home pages.

PubMed

Stokes, Carla E

2007-01-01

Despite the importance of media in the lives of girls, sexuality researchers have largely overlooked how Black American adolescent girls engage with media to construct sexual self-definitions and explore their emerging sexuality. This study investigated sexual scripts, self-definition, and hip hop culture in internet home pages constructed by Black girls aged 14-17 years residing in southern states in the USA. Although some girls in the sample constructed sexual self-representations that mirrored sexual scripts portrayed in the media, hip hop, and youth cyberculture, others resisted stereotypical representations of Black female sexuality. This paper discusses the dominant sexual scripts that emerged from in-depth analysis of 27 home pages constructed by girls residing in Georgia. The focus is on 'Freaks', 'Virgins', 'Down-Ass Chicks/Bitches', 'Pimpettes', and Resisters. Findings suggest that a one-size-fits-all approach to sexuality education may fail to address key contextual issues of relevance to girls and young women. Innovative sexuality and media education strategies that respond to the significance of media in the lives of Black American girls and young women are needed.

Despite on-going debate about credibility, and reported limitations in comparison to other approaches, case study is an increasingly popular approach among qualitative researchers. We critically analysed the methodological descriptions of published case studies. Three high-impact qualitative methods journals were searched to locate case studies published in the past 5 years; 34 were selected for analysis. Articles were categorized as health and health services (n=12), social sciences and anthropology (n=7), or methods (n=15) case studies. The articles were reviewed using an adapted version of established criteria to determine whether adequate methodological justification was present, and if study aims, methods, and reported findings were consistent with a qualitative case study approach. Findings were grouped into five themes outlining key methodological issues: case study methodology or method, case of something particular and case selection, contextually bound case study, researcher and case interactions and triangulation, and study design inconsistent with methodology reported. Improved reporting of case studies by qualitative researchers will advance the methodology for the benefit of researchers and practitioners. PMID:24809980

A Mobile App to Improve Self-Management of Individuals With Type 2 Diabetes: Qualitative Realist Evaluation.

Desveaux, Laura; Shaw, James; Saragosa, Marianne; Soobiah, Charlene; Marani, Husayn; Hensel, Jennifer; Agarwal, Payal; Onabajo, Nike; Bhatia, R Sacha; Jeffs, Lianne

2018-03-16

The increasing use of Web-based solutions for health prevention and promotion presents opportunities to improve self-management and adherence to guideline-based therapy for individuals with type 2 diabetes (T2DM). Despite promising preliminary evidence, many users stop using Web-based solutions due to the burden of data entry, hidden costs, loss of interest, and a lack of comprehensive features. Evaluations tend to focus on effectiveness or impact and fail to evaluate the nuanced variables that may interact to contribute to outcome success (or failure). This study aimed to evaluate a Web-based solution for improving self-management in T2DM to identify key combinations of contextual variables and mechanisms of action that explain for whom the solution worked best and in what circumstances. A qualitative realist evaluation was conducted with one-on-one, semistructured telephonic interviews completed at baseline, and again toward the end of the intervention period (3 months). Topics included participants' experiences of using the Web-based solution, barriers and facilitators of self-management, and barriers and facilitators to effective use. Transcripts were analyzed using thematic analysis strategies, after which the key themes were used to develop statements of the relationships between the key contextual factors, mechanisms of action, and impact on the primary outcome (glycated hemoglobin, HbA 1c ). Twenty-six interviews (14 baseline, 12 follow-up) were completed with 16 participants with T2DM, and the following 3 key groups emerged: the easiest fit, the best fit, and those who failed to activate. Self-efficacy and willingness to engage with the solution facilitated improvement in HbA 1c , whereas competing priorities and psychosocial issues created barriers to engagement. Individuals with high baseline self-efficacy who were motivated, took ownership for their actions, and prioritized diabetes management were early and eager adopters of the app and recorded improvements in HbA 1c over the intervention period. Individuals with moderate baseline self-efficacy and no competing priorities, who identified gaps in understanding of how their actions influence their health, were slow to adopt use but recorded the greatest improvements in HbA 1c . The final group had low baseline self-efficacy and identified a range of psychosocial issues and competing priorities. These participants were uncertain of the benefits of using a Web-based solution to support self-management, ultimately resulting in minimal engagement and no improvement in HbA 1c . Self-efficacy, competing priorities, previous behavior change, and beliefs about Web-based solutions interact to determine engagement and impact on the clinical outcomes. Considering the balance of these patient characteristics is likely to help health care providers identify individuals who are apt to benefit from a Web-based solution to support self-management of T2DM. Web-based solutions could be modified to incorporate the existing screening measures to identify individuals who are at risk of suboptimal adherence to inform the provision of additional support(s) as needed. ©Laura Desveaux, James Shaw, Marianne Saragosa, Charlene Soobiah, Husayn Marani, Jennifer Hensel, Payal Agarwal, Nike Onabajo, R Sacha Bhatia, Lianne Jeffs.

Intercultural communication in health care: challenges and solutions in work rehabilitation practices and training: a comprehensive review.

PubMed

Côté, Daniel

2013-01-01

The purpose of this comprehensive literature review it to explore cross-cultural issues in occupational rehabilitation and work disability prevention. A literature review on cross-cultural issues was performed in medicine, health sciences, and social sciences databases (PubMed, Ingenta, Canadian Centre for Occupational Health and Safety, Ergonomics Abstract, Google Scholar, OSH Update and the Quebec Workers' Compensation Board data base). A total of 27 documents published until 2010 in English or French were selected and analyzed. Cross-cultural issues in occupational rehabilitation show that representations of pain, communication and therapist-patient relationship and intercultural competence could be presented as the major topics covered in the selected literature. As for the general topic of immigrant workers and OSH, barriers were identified revealing personal, relational, contextual and structural levels that put immigrant and minority workers in situation of vulnerability (ex. linguistic and cultural barriers, lack of knowledge of the system, precarious work or exposition to higher risk hazards, etc.). Cultural issues in occupational rehabilitation put less attention to work-related contextual factors but emphasized on attitude and pain behaviours, perceptions of illness and appropriate treatment, therapist-patient relationship and cultural competences among OT professionals. The growth of immigration in countries such as Canada poses a real challenge to the delivery of health care and rehabilitation services. Despite growing concerns in providing culturally appropriate heath cares, intervention models, tools and training tools are still lacking in occupational rehabilitation and disability management. Nevertheless, cultural competence seems to be a promising concept to be implemented in work rehabilitation and disability management.

In search of a theoretical structure for understanding motivation in schizophrenia.

PubMed

Medalia, Alice; Brekke, John

2010-09-01

This themed issue considers different ways to conceptualize the motivational impairment that is a core negative symptom of schizophrenia. Motivational impairment has been linked to poor functional outcome, thus it is important to understand the nature and causes of motivational impairment in order to develop better treatment strategies to enhance motivation and engage patients in the process of recovery. Motivation refers to the processes whereby goal-directed activities are instigated and sustained and can be thought of as the product of a complex interaction of physiological processes and social contextual variables. In this issue, the physiological processes of motivation are the focus of Barch and Dowd, who highlight the role of prefrontal and subcortical mesolimbic dopamine systems in incentive-based learning and the difficulties people with schizophrenia have using internal representations of relevant experiences and goals to drive the behavior that should allow them to obtain desired outcomes. The articles in this issue by Choi et al., Nakagami et al., and Silverstein, focus on social contextual or environmental variables that can shape behavior and motivation. Together, these articles highlight the impact of external cues and goal properties on the expectations and values attached to goal outcomes. Expectancy-value and Self-Determination theories provide an overarching framework to accommodate the perspectives and data provided in all these articles. In the following introduction we show how the articles in this themed issue both support the role of expectancies and value in motivation in schizophrenia and elucidate possible deficiencies in the way expectations and value get assigned.

Brief structured physical activity in the classroom is effective for increasing student physical activity. The present study investigated the association between implementation-related contextual factors and intervention implementation after adoption of a structured classroom physical activity intervention. Six elementary-school districts adopted structured classroom physical activity programs in 2013-2014. Implementation contextual factors and intervention implementation (structured physical activity provided in past week or month, yes/no) were assessed using surveys of 337 classroom teachers from 24 schools. Mixed-effects models accounted for the nested design. Availability of resources (yes/no, ORs = 1.91-2.93) and implementation climate z-scores (ORs = 1.36-1.47) were consistently associated with implementation. Teacher-perceived classroom behavior benefits (OR = 1.29) but not student enjoyment or health benefits, and time (OR = 2.32) and academic (OR = 1.63) barriers but not student cooperation barriers were associated with implementation (all z-scores). Four implementation contextual factor composites had an additive association with implementation (OR = 1.64 for each additional favorable composite). Training and technical assistance alone may not support a large proportion of teachers to implement structured classroom physical activity. In addition to lack of time and interference with academic lessons, school climate related to whether administrators and other teachers were supportive of the intervention were key factors explaining whether teachers implemented the intervention. Evidence-based implementation strategies are needed for effectively communicating the benefits of classroom physical activity on student behavior and improving teacher and administrator climate/attitudes around classroom physical activity.

Background The ability to integrate contextual information with social cues to generate social meaning is a key aspect of social cognition. It is widely accepted that patients with schizophrenia and bipolar disorders have deficits in social cognition; however, previous studies on these disorders did not use tasks that replicate everyday situations. Methodology/Principal Findings This study evaluates the performance of patients with schizophrenia and bipolar disorders on social cognition tasks (emotional processing, empathy, and social norms knowledge) that incorporate different levels of contextual dependence and involvement of real-life scenarios. Furthermore, we explored the association between social cognition measures, clinical symptoms and executive functions. Using a logistic regression analysis, we explored whether the involvement of more basic skills in emotional processing predicted performance on empathy tasks. The results showed that both patient groups exhibited deficits in social cognition tasks with greater context sensitivity and involvement of real-life scenarios. These deficits were more severe in schizophrenic than in bipolar patients. Patients did not differ from controls in tasks involving explicit knowledge. Moreover, schizophrenic patients’ depression levels were negatively correlated with performance on empathy tasks. Conclusions/Significance Overall performance on emotion recognition predicted performance on intentionality attribution during the more ambiguous situations of the empathy task. These results suggest that social cognition deficits could be related to a general impairment in the capacity to implicitly integrate contextual cues. Important implications for the assessment and treatment of individuals with schizophrenia and bipolar disorders, as well as for neurocognitive models of these pathologies are discussed.

Contextual advertisement placement in printed media

NASA Astrophysics Data System (ADS)

Liu, Sam; Joshi, Parag

2010-02-01

Advertisements today provide the necessary revenue model supporting the WWW ecosystem. Targeted or contextual ad insertion plays an important role in optimizing the financial return of this model. Nearly all the current ads that appear on web sites are geared for display purposes such as banner and "pay-per-click". Little attention, however, is focused on deriving additional ad revenues when the content is repurposed for alternative mean of presentation, e.g. being printed. Although more and more content is moving to the Web, there are still many occasions where printed output of web content is desirable, such as maps and articles; thus printed ad insertion can potentially be lucrative. In this paper, we describe a contextual ad insertion network aimed to realize new revenue for print service providers for web printing. We introduce a cloud print service that enables contextual ads insertion, with respect to the main web page content, when a printout of the page is requested. To encourage service utilization, it would provide higher quality printouts than what is possible from current browser print drivers, which generally produce poor outputs, e.g. ill formatted pages. At this juncture we will limit the scope to only article-related web pages although the concept can be extended to arbitrary web pages. The key components of this system include (1) the extraction of article from web pages, (2) the extraction of semantics from article, (3) querying the ad database for matching advertisement or coupon, and (4) joint content and ad layout for print outputs.

ABSTRACT Background: Professional regulation is one of the strategies of the governments which protect the public’s right. Nursing practice is not an exception; hence, it is regulated to protect the public against nursing services’ adverse effects. Although modern nursing in Iran started from 100 years ago, documents show that there was no regulation mechanism for nursing in Iran till 2016. Hence, this study was conducted to illuminate the contextual factors affecting the nursing regulation process in Iran. Methods: To explore the contextual elements of late establishment of nursing registration as an important part of nursing regulation, we applied directed qualitative content analysis. For this purpose, all the historical events and related materials including articles published in scientific journals, gray literature, statements, news articles, and interviews in the period of 2006-2016 were reviewed and analyzed by expert panel and categorized in predetermined groups. Results: Pooled analysis data showed four contributing elements that affected the emerging nursing regulation in Iran. These elements include 1) cultural determinants, 2) structural determinants, 3) situational determinants, and 4) international or exogenous determinants. Conclusion: Nursing regulation is an important health policy issue in Iran which needs to be facilitated by contextual factors. These factors are complicated and country-specific. Political willingness should be accompanied by nursing association willingness to establish and improve nursing regulation. Other researches are recommended to explore actors and process and content of nursing regulation policy in Iran. PMID:29607341

Motivation in sport has been frequently identified as a key factor of young athletes' intention of doping in sport, but there has not been any attempt in scrutinizing the motivational mechanism involved. The present study applied the trans-contextual model of motivation to explain the relationship between motivation in a sport context and motivation and the social-cognitive factors (attitude, subjective norm, perceived behavioral control, and intention) from the theory of planned behavior (TPB) in an anti-doping context. A cross-sectional survey was conducted. Questionnaire data was collected from 410 elite and sub-elite young athletes in Australia (Mean age [17.7±3.9 yr], 55.4% male, Years in sport [9.1±3.2]). We measured the key model variables of study in relation to sport motivation (Behavioral Regulation in Sport Questionnaire), and the motivation (adapted version of the Treatment Self-Regulation Questionnaire) and social cognitive patterns (the theory of planned behavior questionnaire) of doping avoidance. The data was analyzed by variance-based structural equation modeling with bootstrapping of 999 replications. The goodness-of-fit of the hypothesized model was acceptable. The bootstrapped parameter estimates revealed that autonomous motivation and amotivation in sport were positively associated with the corresponding types of motivation for the avoidance of doping. Autonomous motivation, subjective norm, and perceived behavioral control in doping avoidance fully mediated the relationship between autonomous motivation in sport and intention for doping avoidance. The findings support the tenets of the trans-contextual model, and explain how motivation in sport is related to athletes' motivation and intention with respect to anti-doping behaviors.

Paramedics make important and increasingly complex decisions at scene about patient care. Patient safety implications of influences on decision making in the pre-hospital setting were previously under-researched. Cutting edge perspectives advocate exploring the whole system rather than individual influences on patient safety. Ethnography (the study of people and cultures) has been acknowledged as a suitable method for identifying health care issues as they occur within the natural context. In this paper we compare multiple methods used in a multi-site, qualitative study that aimed to identify system influences on decision making. The study was conducted in three NHS Ambulance Trusts in England and involved researchers from each Trust working alongside academic researchers. Exploratory interviews with key informants e.g. managers (n = 16) and document review provided contextual information. Between October 2012 and July 2013 researchers observed 34 paramedic shifts and ten paramedics provided additional accounts via audio-recorded 'digital diaries' (155 events). Three staff focus groups (total n = 21) and three service user focus groups (total n = 23) explored a range of experiences and perceptions. Data collection and analysis was carried out by academic and ambulance service researchers as well as service users. Workshops were held at each site to elicit feedback on the findings and facilitate prioritisation of issues identified. The use of a multi-method qualitative approach allowed cross-validation of important issues for ambulance service staff and service users. A key factor in successful implementation of the study was establishing good working relationships with academic and ambulance service teams. Enrolling at least one research lead at each site facilitated the recruitment process as well as study progress. Active involvement with the study allowed ambulance service researchers and service users to gain a better understanding of the research process. Feedback workshops allowed stakeholders to discuss and prioritise findings as well as identify new research areas. Combining multiple qualitative methods with a collaborative research approach can facilitate exploration of system influences on patient safety in under-researched settings. The paper highlights empirical issues, strengths and limitations for this approach. Feedback workshops were effective for verifying findings and prioritising areas for future intervention and research.

The application of digital monitoring biomarkers in health, wellness and disease management is reviewed. Harnessing the near limitless capacity of these approaches in the managed healthcare continuum will benefit from a systems-based architecture which presents data quality, quantity, and ease of capture within a decision-making dashboard. A framework was developed which stratifies key components and advances the concept of contextualized biomarkers. The framework codifies how direct, indirect, composite, and contextualized composite data can drive innovation for the application of digital biomarkers in healthcare. The de novo framework implies consideration of physiological, behavioral, and environmental factors in the context of biomarker capture and analysis. Application in disease and wellness is highlighted, and incorporation in clinical feedback loops and closed-loop systems is illustrated. The study of contextualized biomarkers has the potential to offer rich and insightful data for clinical decision making. Moreover, advancement of the field will benefit from innovation at the intersection of medicine, engineering, and science. Technological developments in this dynamic field will thus fuel its logical evolution guided by inputs from patients, physicians, healthcare providers, end-payors, actuarists, medical device manufacturers, and drug companies.

The current paper introduces relational frame theory (RFT) as a functional contextual approach to complex human behaviour and examines how this theory has contributed to our understanding of several key phenomena in psychological science. I will first briefly outline the philosophical foundation of RFT and then examine its conceptual basis and core concepts. Thereafter, I provide an overview of the empirical findings and applications that RFT has stimulated in a number of key domains such as language development, linguistic generativity, rule-following, analogical reasoning, intelligence, theory of mind, psychopathology and implicit cognition. © 2015 International Union of Psychological Science.

Exploring the Framing of Animal Farming and Meat Consumption: On the Diversity of Topics Used and Qualitative Patterns in Selected Demographic Contexts

2018-01-01

Simple Summary In various contexts, people talk about the farming and consumption of animals using different arguments to construct and justify their (non-)acceptability. This paper reports on a qualitative research among consumers with different backgrounds in urban and rural areas in The Netherlands and Turkey. We present an elaborate methodology for qualitatively researching everyday-life talk about animal farming and meat consumption. We explain how we collected and organised topics people refer to, and looked at the possible relation of complete argumentations with the researched contexts. The resulting long list of topics includes animal welfare arguments, but shows that in everyday-life many others are used, such as health, taste, money, religion, and environmental impact. Our research indicates several ties between mentioned topics and the researched contexts—the most noticeable pattern being the difference between respondents in cities and rural areas. However, in contrast to what literature suggests, single contextual features, like country or gender, offered relatively little insight into the differences that showed up in the complete argumentations. This, we argue, does not imply that context does not matter, but rather that so many cultural and personal contextual aspects play a role that singular contextual features cannot sufficiently explain framing. Abstract In various contexts, people talk about animal farming and meat consumption using different arguments to construct and justify their (non-)acceptability. This article presents the results of an in-depth qualitative inquiry into the content of and contextual patterns in the everyday-life framing regarding this issue, performed among consumers in various settings in two extremes in the European sphere: the Netherlands and Turkey. We describe the methodological steps of collecting, coding, and organizing the variety of encountered framing topics, as well as our search for symbolic convergence in groups of consumers from different selected demographic contexts (country, urban-rural areas, gender, age, and education level). The framing of animal farming and meat consumption in everyday-life is not a simple one-issue rational display of facts; people referred to a vast range of topics in the categories knowledge, convictions, pronounced behaviour, values, norms, interests, and feelings. Looking at framing in relation to the researched demographic contexts, most patterns were found on the level of topics; symbolic convergence in lines of reasoning and composite framing was less prominent in groups based on single demographic contexts than anticipated. An explanation for this lies in the complexity of frame construction, happening in relation with multiple interdependent contextual features. PMID:29364860

Contextual assessment in science education: Background, issues, and policy

NASA Astrophysics Data System (ADS)

Klassen, Stephen

2006-09-01

Contemporary assessment practices in science education have undergone significant changes in recent decades. The basis for these changes and the resulting new assessment practices are the subject of this two-part paper. Part 1 considers the basis of assessment that, more than 25 years ago, was driven by the assumptions of decomposability and decontextualization of knowledge, resulting in a low-inference testing system, often described as traditional. This assessment model was replaced not on account of direct criticism, but rather on account of a larger revolution - the change from behavioral to cognitive psychology, developments in the philosophy of science, and the rise of constructivism. Most notably, the study of the active cognitive processes of the individual resulted in a major emphasis on context in learning and assessment. These changes gave rise to the development of various contextual assessment methodologies in science education, for example, concept mapping assessment, performance assessment, and portfolio assessment. In Part 2, the literature relating to the assessment methods identified in Part 1 is reviewed, revealing that there is not much research that supports their validity and reliability. However, encouraging new work on selected-response tests is forming the basis for reconsideration of past criticisms of this technique. Despite the major developments in contextual assessment methodologies in science education, two important questions remain unanswered, namely, whether grades can be considered as genuine numeric quantities and whether the individual student is the appropriate unit of assessment in public accountability. Given these issues and the requirement for science assessment to satisfy the goals of the individual, the classroom, and the society, tentative recommendations are put forward addressing these parallel needs in the assessment of science learning.

Quantum Bayesian perspective for intelligence reservoir characterization, monitoring and management

2017-10-01

The paper starts with a brief review of the literature about uncertainty in geological, geophysical and petrophysical data. In particular, we present the viewpoints of experts in geophysics on the application of Bayesian inference and subjective probability. Then we present arguments that the use of classical probability theory (CP) does not match completely the structure of geophysical data. We emphasize that such data are characterized by contextuality and non-Kolmogorovness (the impossibility to use the CP model), incompleteness as well as incompatibility of some geophysical measurements. These characteristics of geophysical data are similar to the characteristics of quantum physical data. Notwithstanding all this, contextuality can be seen as a major deviation of quantum theory from classical physics. In particular, the contextual probability viewpoint is the essence of the Växjö interpretation of quantum mechanics. We propose to use quantum probability (QP) for decision-making during the characterization, modelling, exploring and management of the intelligent hydrocarbon reservoir. Quantum Bayesianism (QBism), one of the recently developed information interpretations of quantum theory, can be used as the interpretational basis for such QP decision-making in geology, geophysics and petroleum projects design and management. This article is part of the themed issue `Second quantum revolution: foundational questions'.

Ethical decision making in the conduct of research: role of individual, contextual and organizational factors. Commentary on "Science, human nature, and a new paradigm for ethics education".

PubMed

Langlais, Philip J

2012-09-01

Despite the importance of scientific integrity to the well-being of society, recent findings suggest that training and mentoring in the responsible conduct of research are not very reliable or effective inhibitors of research misbehavior. Understanding how and why individual scientists decide to behave in ways that conform to or violate norms and standards of research is essential to the development of more effective training programs and the creation of more supportive environments. Scholars in business management, psychology, and other disciplines have identified many important factors that affect ethical behavior, including individual, contextual, and organizational factors. Surprisingly little research has been conducted to examine the role of these factors in either the development of ethical decision-making skills, or their applicability to ethical issues commonly encountered in research and other scholarly and professional activities. Interdisciplinary approaches combined with research and discipline relevant paradigms should greatly enhance understanding of the individual contextual and organizational factors involved in ethical and unethical research conduct. Such studies will inform and facilitate the development of more effective ethics education programs in the sciences and engineering professions.

We discuss the articles of this special issue with reference to an important yet previously only implicit dimension of study quality: alignment across the theoretical and methodological decisions that collectively define an approach to self-regulated learning. Integrating and extending work by leaders in the field, we propose a framework for evaluating alignment in the way self-regulated learning research is both conducted and reported. Within this framework, the special issue articles provide a springboard for discussing methodological promises and pitfalls of increasingly sophisticated research on the dynamic, contingent, and contextualized features of self-regulated learning.

Organ shortage: the greatest challenge facing transplant medicine.

PubMed

Shafran, David; Kodish, Eric; Tzakis, Andreas

2014-07-01

The success of organ transplantation as a treatment for end-stage organ disease has yielded a series of ethical quandaries originating from the issue of organ shortage. Scarcity of organs for transplantation necessitates formulation of just and fair allocation policies as well as ethically viable solutions to bridging the vast gap between organ supply and demand. The concept of "triage" provides a useful paradigm in which to contextualize the organ shortage issue. This entails subjugating the welfare of the individual patient for the benefit of the wider community as an ethically justified response to the challenge of scarcity.

Reversing the Downward Spiral of Science Instruction in K-2 Classrooms

Sandholtz, Judith Haymore; Ringstaff, Cathy

2011-10-01

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2 classrooms in rural school districts. The research specifically examined changes in (a) teachers' content knowledge in science; (b) teachers' self-efficacy related to teaching science; (c) classroom instructional time allotted to science; and (d) instructional strategies used in science. The study also investigated contextual factors contributing to or hindering changes in science instruction. Data sources included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and classroom observations. After one year in the program, teachers showed increased content knowledge and self-efficacy in teaching science; they spent more instructional time on science and began using different instructional strategies. Key contextual factors included curricular demands, resources, administrative support, and support from other teachers.

Efficient visualization of urban spaces

2012-10-01

This chapter presents a new method for calculating efficiency and applies that method to the issues of selecting simulation media and evaluating the contextual fit of new buildings in urban spaces. The new method is called "meta-analysis". A meta-analytic review of 967 environments indicated that static color simulations are the most efficient media for visualizing urban spaces. For contextual fit, four original experiments are reported on how strongly five factors influence visual appeal of a street: architectural style, trees, height of a new building relative to the heights of existing buildings, setting back a third story, and distance. A meta-analysis of these four experiments and previous findings, covering 461 environments, indicated that architectural style, trees, and height had effects strong enough to warrant implementation, but the effects of setting back third stories and distance were too small to warrant implementation.

This paper reports the process by which a personalized cancer treatment system was built, following a user-centered approach. We give some background on personalized cancer treatment, the particular tumor chemosensitivity assay supported by the system, as well as some quality and legal issues related to such health systems. We describe how Contextual Design was applied when building the system. Contextual design is a user-centered design technique involving seven steps. We also provide some details about the system implementation. Finally, we explain how the Think-Aloud protocol and Heuristic Evaluation methods were used to evaluate the system and report its results. A qualitative assessment from the users perspective is also provided. Results from the heuristic evaluation indicate that only one of ten heuristics was missing from the system, while five were partially covered and four were fully covered.

Medial prefrontal cortex serotonergic and GABAergic mechanisms modulate the expression of contextual fear: intratelencephalic pathways and differential involvement of cortical subregions.

PubMed

Almada, R C; Coimbra, N C; Brandão, M L

2015-01-22

Several lines of evidence indicate that the dorsal hippocampus (dH) and medial prefrontal cortex (mPFC) regulate contextual fear conditioning. The prelimbic (PrL), infralimbic (IL) and the anterior cingulate cortex (ACC) subregions of the mPFC likely play distinct roles in the expression of fear. Moreover, studies have highlighted the role of serotonin (5-hydroxytryptamine, 5-HT)- and γ-aminobutyric acid (GABA)-mediated mechanisms in the modulation of innate fear in the mPFC. The present study characterized dH-mPFC pathways and investigated the role of serotonergic and GABAergic mechanisms of the PrL, IL and ACC-area 1 (Cg1) in the elaboration of contextual fear conditioning using fear-potentiated startle (FPS) and freezing behavior in Rattus norvegicus. The results of neurotracing with microinjections of biotinylated dextran amine into the dH revealed a neural link of the dH with the PrL and ACC. Intra-PrL injections of the 5-HT1A receptor agonist 8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) and the GABAA receptor-selective agonist muscimol reduced contextual FPS and freezing responses. Intra-Cg1 injections of muscimol but not 8-OH-DPAT decreased FPS and freezing responses. However, neither intra-IL injections of a 5-HT1A agonist nor of a GABAA agonist affected these defensive responses. Labeled neuronal fibers from the dH reached the superficial layers of the PrL cortex and spread to the inner layers of PrL and Cg1 cortices, supporting the pharmacological findings. The present results confirmed the involvement of PrL and Cg1 in the expression of FPS and freezing responses to aversive conditions. In addition, PrL serotoninergic mechanisms play a key role in contextual fear conditioning. This study suggests that PrL, IL and Cg1 distinctively contribute to the modulation of contextual fear conditioning. Copyright © 2014 IBRO. Published by Elsevier Ltd. All rights reserved.

Teaching the content in context: Preparing "highly qualified" and "high quality" teachers for instruction in underserved secondary science classrooms

NASA Astrophysics Data System (ADS)

Tolbert, Sara E.

2011-12-01

This dissertation research project presents the results of a longitudinal study that investigates the knowledge, beliefs, and practices of 13 preservice secondary science teachers participating in a science teacher credentialing/Masters program designed to integrate issues of equity and diversity throughout coursework and seminars. Results are presented in the form of three papers: The first paper describes changes in preservice teacher knowledge about contextualization in science instruction, where contextualization is defined as facilitating authentic connections between science learning and relevant personal, social, cultural, ecological, and political contexts of students in diverse secondary classrooms; the second paper relates changes in the self-efficacy and content-specific beliefs about science, science teaching, diversity, and diversity in science instruction; and the final paper communicates the experiences and abilities of four "social justice advocates" learning to contextualize science instruction in underserved secondary placement classrooms. Results indicate that secondary student teachers developed more sophisticated understandings of how to contextualize science instruction with a focus on promoting community engagement and social/environmental activism in underserved classrooms and how to integrate science content and diversity instruction through student-centered inquiry activities. Although most of the science teacher candidates developed more positive beliefs about teaching science in underrepresented classrooms, many teacher candidates still attributed their minority students' underperformance and a (perceived) lack of interest in school to family and cultural values. The "social justice advocates" in this study were able to successfully contextualize science instruction to varying degrees in underserved placement classrooms, though the most significant limitations on their practice were the contextual factors of their student teaching placements---in particular, the extent to which their cooperating teachers gave them the autonomy and planning time to design and implement their own activities and lessons. While the "integrated approach" to diversity and equity in science teacher education was, overall, successful in helping preservice teachers' move closer toward developing the beliefs, knowledge, and practices necessary for effective instruction in underserved classrooms, suggestions are given for increasing the effectiveness of the "integrated approach," particularly in the context of a one-year credentialing program.

Prenatal records are potentially powerful tools for the translation of best-practice evidence into routine prenatal care. Although all jurisdictions in Canada use standardized prenatal records to guide care and provide data for health surveillance, their content related to risk factors such as maternal smoking and alcohol use varies widely. Literature is lacking on how prenatal records are developed or updated to integrate research evidence. This multiphase project aimed to identify key contextual factors influencing decision-making and evidence use among Canadian prenatal record committees (PRCs), and formulate recommendations for the prenatal record review process in Canada. Phase 1 comprised key informant interviews with PRC leaders across 10 Canadian jurisdictions. Phase 2, was a qualitative comparative case study of PRC factors influencing evidence-use and decision-making in five selected jurisdictions. Interview data were analysed using qualitative content analysis. Phase 3 involved a dissemination workshop with key stakeholders to review and refine recommendations derived from Phases 1 and 2. Prenatal record review processes differed considerably across Canadian jurisdictions. PRC decision-making was complex, revealing the competing functions of the prenatal record as a clinical guide, documentation tool and data source. Internal contextual factors influencing evidence use included PRC resources to conduct evidence reviews; group composition and dynamics; perceived function of the prenatal record; and expert opinions. External contextual factors included concerns about user buy-in; health system capacities; and pressures from public health stakeholders. Our recommendations highlight the need for: broader stakeholder involvement and explicit use of decision-support strategies to support the revision process; a national template of evidence-informed changes that can be used across jurisdictions; consideration of both clinical and surveillance functions of the prenatal record; and dissemination plans to communicate prenatal record modifications. Decision-making related to prenatal record content involves a negotiated effort to balance research evidence with the needs and preferences of prenatal care providers, health system capacities as well as population health priorities. The development of a national template for prenatal records would reduce unnecessary duplication of PRC work and enhance the consistency of prenatal care delivery and perinatal surveillance data across Canada.

Health care professionals, especially those working in primary health-care services, can play a key role in preventing and responding to intimate partner violence. However, there are huge variations in the way health care professionals and primary health care teams respond to intimate partner violence. In this study we tested a previously developed programme theory on 15 primary health care center teams located in four different Spanish regions: Murcia, C Valenciana, Castilla-León and Cantabria. The aim was to identify the key combinations of contextual factors and mechanisms that trigger a good primary health care center team response to intimate partner violence. A multiple case-study design was used. Qualitative and quantitative information was collected from each of the 15 centers (cases). In order to handle the large amount of information without losing familiarity with each case, qualitative comparative analysis was undertaken. Conditions (context and mechanisms) and outcomes, were identified and assessed for each of the 15 cases, and solution formulae were calculated using qualitative comparative analysis software. The emerging programme theory highlighted the importance of the combination of each team's self-efficacy, perceived preparation and women-centredness in generating a good team response to intimate partner violence. The use of the protocol and accumulated experience in primary health care were the most relevant contextual/intervention conditions to trigger a good response. However in order to achieve this, they must be combined with other conditions, such as an enabling team climate, having a champion social worker and having staff with training in intimate partner violence. Interventions to improve primary health care teams' response to intimate partner violence should focus on strengthening team's self-efficacy, perceived preparation and the implementation of a woman-centred approach. The use of the protocol combined with a large working experience in primary health care, and other factors such as training, a good team climate, and having a champion social worker on the team, also played a key role. Measures to sustain such interventions and promote these contextual factors should be encouraged.

Why do we have such difficulty assessing aerosol impacts in Southeast Asia? Examining the representativeness of regional in situ, remote sensing, and modeling data using examples from a recent field trial

Southeast Asia faces numerous climate change issues, and the interaction between aerosol particles, clouds, and precipitation is thought to impact the environment in this region at both weather and climate scales. Aerosol particles have direct radiative effects, indirect effects through interaction with clouds and precipitation, and also act as a tracer for other processes affecting the carbon cycle or atmospheric chemistry. Southeast Asia also hosts some of the most complex meteorological phenomenon of the world, challenging in situ, remote sensing and modeling systems. Indeed, there is more diversity in satellite based aerosol, fire, cloud, and precipitation products in Southeast Asia than perhaps anywhere else in the world outside of the poles. In addition to serious direct challenges to aerosol observability in Southeast Asia, such as persistent ubiquitous cloud cover, there are also contextual biases (such as for aerosol retrievals the classic clear sky bias). Contextual bias affects the representativeness of nearly all aerosol assessments in Southeast Asia. As part of the 7 Southeast Asian Studies (7SEAS) program, a small intensive study was conducted in Singapore and the Palawan Archipelago in September 2011 to study the flow of biomass burning smoke through the South China/East Sea and into the summertime monsoonal trough. Analysis of field data coupled with multiple satellite and model products allowed us to investigate questions on the representativeness of data and to what extent they capture the 'true' state of the meteorological and aerosol environment. Four specific representativeness issues are presented based on IOP examples: 1) Individual biases in retrievals or model simulations; 2) Sampling biases at short time scales based on product coverage; 3) Temporal and spatial scale biases inherent in large and point based measurements; 4) Contextual biases that develop from the aggregation of data products. Considering all four of these issues we conclude with a discussion of strategies for hypothesis testing and the development of regional state vectors with realistic uncertainties.

Generating political will for safe motherhood in Indonesia.

Shiffman, Jeremy

2003-03-01

In 1987 an international conference brought global attention to an issue that previously had been ignored: the world's alarmingly high number of maternal deaths in childbirth. The conference ended with a declaration calling for a reduction in maternal mortality by at least half by the year 2000. As the deadline approached, safe motherhood activists lamented the fact that the world was nowhere near to achieving this objective. They attributed this failure to a variety of causes, but were in agreement that the medical technology was available to prevent maternal deaths in childbirth, and the key was generating the political will to make such technology widely available to women in developing countries.What 'political will' means, however, has been left as an unopened black box. What causes governments to give priority to the issue of safe motherhood, given that national political systems are burdened with thousands of issues to sort through each year? In marked contrast to our extensive knowledge about the medical interventions necessary to prevent maternal death, we know little about the political interventions necessary to increase the likelihood that national leaders pay meaningful attention to the issue. Drawing from a scholarly literature on agenda setting, this paper identifies four factors that heighten the likelihood that an issue will rise to national-level attention: the existence of clear indicators showing that a problem exists; the presence of effective political entrepreneurs to push the cause; the organization of attention-generating focusing events that promote widespread concern for the issue; and the availability of politically palatable policy alternatives that enable national leaders to understand that the problem is surmountable. The paper presents a case study of the emergence, waning and re-generation of political priority for safe motherhood in Indonesia over the decade 1987-1997, to highlight how these four factors interacted to raise safe motherhood from near obscurity in the country to national-level prominence. While there are contextual factors that make this case unique, some elements are applicable to all developing countries. The paper draws out these dimensions in the hope that greater knowledge surrounding how political will actually has been generated can help shape strategic action to address this much neglected global problem.

International medical volunteering has grown in recent decades. It has the potential to benefit and harm the volunteer and host countries; but there is a paucity of literature on the impacts of international medical volunteering and a need to find ways to optimise the benefits of such placements. In this study, one example of international medical volunteering was examined involving British GPs on short-term placements in Nepal. The intention was to explore the expectations and experiences of the local health workers, volunteers, and host organisation to try and understand what makes volunteer placements work. Qualitative study of key informant interviews. Stakeholders of a short-term international medical volunteer (IMV) placement programme in Nepal. Key informant interviews were carried out via face-to-face or telephone/internet interviews with five previous volunteers, three representatives from a non-governmental organisation providing placements, and five local health workers in Nepal who had had contact with the IMVs. Interviews were recorded, transcribed, and analysed using standard thematic framework approaches. All the stakeholders had their own specific motives for participating in the IMV programme. The relationship between volunteers and the Nepalese health workers was complex and characterised by discrepant and occasionally unrealistic expectations. Managing these different expectations was challenging. Contextual issues and cultural differences are important considerations in medical volunteer programmes, and this study highlights the importance of robust preparation pre-placement for the volunteer and host to ensure positive outcomes. © British Journal of General Practice 2014.

The TERMIS-Europe (EU) Industry committee intended to address the two main critical issues in the clinical/commercial translation of Advanced Therapeutic Medicine Products (ATMP): (1) entrepreneurial exploitation of breakthrough ideas and innovations, and (2) regulatory market approval. Since January 2012, more than 12,000 publications related to regenerative medicine and tissue engineering have been accepted for publications, reflecting the intense academic research activity in this field. The TERMIS-EU 2014 Industry Symposium provided a reflection on the management of innovation and technological breakthroughs in biotechnology first proposed to contextualize the key development milestones and constraints of allocation of financial resources, in the development life-cycle of radical innovation projects. This was illustrated with the biofuels story, sharing similarities with regenerative medicine. The transition was then ensured by an overview of the key identified challenges facing the commercialization of cell therapy products as ATMP examples. Real cases and testimonies were then provided by a palette of medical technologies and regenerative medicine companies from their commercial development of cell and gene therapy products. Although the commercial development of ATMP is still at the proof-of-concept stage due to technology risks, changing policies, changing markets, and management changes, the sector is highly dynamic with a number of explored therapeutic approaches, developed by using a large diversity of business models, both proposed by the experience, pitfalls, and successes of regenerative medicine pioneers, and adapted to the constraint resource allocation and environment in radical innovation projects.

Internationally, funders require stakeholder involvement throughout health technology assessment (HTA). We report successes, challenges, and lessons learned from extensive stakeholder involvement throughout a palliative care case study that demonstrates new concepts and methods for HTA. A 5-step "INTEGRATE-HTA Model" developed within the INTEGRATE-HTA project guided the case study. Using convenience or purposive sampling or directly / indirectly identifying and approaching individuals / groups, stakeholders participated in qualitative research or consultation meetings. During scoping, 132 stakeholders, aged ≥ 18 years in seven countries (England, Italy, Germany, The Netherlands, Norway, Lithuania, and Poland), highlighted key issues in palliative care that assisted identification of the intervention and comparator. Subsequently stakeholders in four countries participated in face-face, telephone and / or video Skype meetings to inform evidence collection and / or review assessment results. An applicability assessment to identify contextual and implementation barriers and enablers for the case study findings involved twelve professionals in the three countries. Finally, thirteen stakeholders participated in a mock decision-making meeting in England. Views about the best methods of stakeholder involvement vary internationally. Stakeholders make valuable contributions in all stages of HTA; assisting decision making about interventions, comparators, research questions; providing evidence and insights into findings, gap analyses and applicability assessments. Key challenges exist regarding inclusivity, time, and resource use. Stakeholder involvement is feasible and worthwhile throughout HTA, sometimes providing unique insights. Various methods can be used to include stakeholders, although challenges exist. Recognition of stakeholder expertise and further guidance about stakeholder consultation methods is needed.

Perceived Barriers and Facilitators for Return to Work Among Colorectal Cancer Survivors: Malaysian Healthcare Professionals Experience-　A Qualitative Inquiry.

2015-06-01

Return to work (RTW) can be a challenging occupational health (OH) issue among previously-employed colorectal cancer survivors. This study aimed to explore the various perceived barriers and facilitators encountered during the RTW process in cancer survivorship, from the perception of healthcare professionals (HCP). Face to face, semistructured interviews were carried out on twelve HCP (government and private sectors) from various disciplines. Data collected were transcribed verbatim and data management was aided by NVivo software 8.0. A new theory from contextual data was generated using open coding, axial coding and selective coding. The HCP shared numerous barriers and facilitators associated with RTW, under four categories. The key barriers were disturbing side effects, psychological barriers (personal factor), compensation (financial factor), poor ability to multitask (work-related factor), long paid medical leaves policy, employer's lackadaisical attitude, lack of knowledge and awareness of RTW (environmental factor). Key facilitators identified were desire to resume working life and to contribute to society (personal factor), financial pressure, maintain organizational health insurance (financial factor), less physically demanding job (work-related factor), supportive workplace and strict organizational policy on medical leaves (environmental factor). While not all HCP were trained in RTW, they all agreed that RTW is important for survivors and workplace. Occupational health doctors have a direct role in helping survivors RTW. Early Intervention on RTW during survivorship should involve occupational health doctors and employers, targeting the modifiable factors (environmental and work-related) to improve RTW after cancer.

Setting healthcare priorities in hospitals: a review of empirical studies.

Barasa, Edwine W; Molyneux, Sassy; English, Mike; Cleary, Susan

2015-04-01

Priority setting research has focused on the macro (national) and micro (bedside) level, leaving the meso (institutional, hospital) level relatively neglected. This is surprising given the key role that hospitals play in the delivery of healthcare services and the large proportion of health systems resources that they absorb. To explore the factors that impact upon priority setting at the hospital level, we conducted a thematic review of empirical studies. A systematic search of PubMed, EBSCOHOST, Econlit databases and Google scholar was supplemented by a search of key websites and a manual search of relevant papers' reference lists. A total of 24 papers were identified from developed and developing countries. We applied a policy analysis framework to examine and synthesize the findings of the selected papers. Findings suggest that priority setting practice in hospitals was influenced by (1) contextual factors such as decision space, resource availability, financing arrangements, availability and use of information, organizational culture and leadership, (2) priority setting processes that depend on the type of priority setting activity, (3) content factors such as priority setting criteria and (4) actors, their interests and power relations. We observe that there is need for studies to examine these issues and the interplay between them in greater depth and propose a conceptual framework that might be useful in examining priority setting practices in hospitals.

A dual-driver model of retention and turnover in the direct care workforce.

PubMed

Mittal, Vikas; Rosen, Jules; Leana, Carrie

2009-10-01

The purpose of this study was to understand the factors associated with turnover and retention of direct care workers. We hypothesize that a dual-driver model that includes individual factors, on-the-job factors, off-the-job factors, and contextual factors can be used to distinguish between reasons for direct care workforces (DCWs) staying on the job or leaving the job. We conducted 7 focus groups with 47 participants. We identified key themes they used to describe their experiences focusing on differences between stayers (had been in the same job for at least 3 years) and leavers (had changed jobs within the past 3 years). Five major themes associated with turnover were identified as follows: (a) lack of respect, (b) inadequate management, (c) work or family conflicts, (d) difficulty of the work, and (e) job openings. Themes associated with retention were as follows: (a) being "called" to service, (b) patient advocacy, (c) personal relationships with residents, (d) religion or spirituality, (e) haven from home problems, and (f) flexibility. Themes associated with turnover were different from those associated with retention. DCW turnover and retention are complex, multifactorial issues. Efforts to stabilize the DCW must address the issues associated with retention as well as those associated with turnover. Specifically, factors that promote retention may be qualitatively different than those that prevent turnover. Treating retention and turnover as simply the obverse of each other may be misleading in addressing the underlying problem of job stability among DCWs.

Discursive construction of polyphony in healthcare management.

PubMed

Hujala, Anneli; Rissanen, Sari

2012-01-01

The aim of the paper is to understand and define how the polyphony of management is constructed in interaction and to describe this through concrete management meeting cases. Polyphony refers to the diverse voices of various organization members, and how these voices are present, disclosed and utilized in management. The study is based on the social constructionist and discursive perspectives of management, which question the traditional, individualistic approaches of management. The issue was examined through a qualitative case study by analysing the micro-level management discourse in three healthcare organizations. Discursive practices that enhance or inhibit polyphony are often unnoticed and unconscious. Key moments of management discourse are an example of unconscious mundane practices through which members of organizations construct the reality of management. The empirical results are locally contextual. In the future, research will be able to apply the approach to diverse contexts as well as link micro-level discourses to the construction of broader health and social management discourses. The paper increases the understanding of how to enhance participation and staff contribution, and how to utilize the knowledge of all members of the organization. Both managers and other staff members are fully involved in the social construction of management. Micro-level discourse should be paid attention to in management work as well as in the education of managers and staff. The study increases the understanding of micro-level issues of management and challenges the conventional, taken-for-granted assumptions behind organization and management theories.

How organizational context affects bioethical decision-making: pharmacists' management of gatekeeping processes in retail and hospital settings.

PubMed

Chiarello, Elizabeth

2013-12-01

Social science studies of bioethics demonstrate that ethics are highly contextual, functioning differently across local settings as actors make daily decisions "on the ground." Sociological studies that demonstrate the key role organizations play in shaping ethical decision-making have disproportionately focused on physicians and nurses working in hospital settings where they contend with life and death issues. This study broadens our understanding of the contexts of ethical decision-making by empirically examining understudied healthcare professionals - pharmacists - working in two organizational settings, retail and hospital, where they act as gatekeepers to regulated goods and services as they contend with ethical issues ranging from the serious to the mundane. This study asks: How do organizations shape pharmacists' identification, negotiation, and resolution of ethical challenges; in other words, how do organizations shape pharmacists' gatekeeping processes? Based on 95 semi-structured interviews with U.S. pharmacists practicing in retail and hospital pharmacies conducted between September 2009 and May 2011, this research finds that organizations influence ethical decision-making by shaping how pharmacists construct four gatekeeping processes: medical, legal, fiscal, and moral. Each gatekeeping process manifests differently across organizations due to how these settings structure inter-professional power dynamics, proximity to patients, and means of accessing information. Findings suggest new directions for theorizing about ethical decision-making in medical contexts by drawing attention to new ethical actors, new organizational settings, an expanded definition of ethical challenges, and a broader conceptualization of gatekeeping.

Rethinking risk assessment for emerging technology first-in-human trials.

PubMed

Genske, Anna; Engel-Glatter, Sabrina

2016-03-01

Recent progress in synthetic biology (SynBio) has enabled the development of novel therapeutic opportunities for the treatment of human disease. In the near future, first-in-human trials (FIH) will be indicated. FIH trials mark a key milestone in the translation of medical SynBio applications into clinical practice. Fostered by uncertainty of possible adverse events for trial participants, a variety of ethical concerns emerge with regards to SynBio FIH trials, including 'risk' minimization. These concerns are associated with any FIH trial, however, due to the novelty of the approach, they become more pronounced for medical applications of emerging technologies (emTech) like SynBio. To minimize potential harm for trial participants, scholars, guidelines, regulations and policy makers alike suggest using 'risk assessment' as evaluation tool for such trials. Conversely, in the context of emTech FIH trials, we believe it to be at least questionable to contextualize uncertainty of potential adverse events as 'risk' and apply traditional risk assessment methods. Hence, this issue needs to be discussed to enable alterations of the evaluation process before the translational phase of SynBio applications begins. In this paper, we will take the opportunity to start the debate and highlight how a misunderstanding of the concept of risk, and the possibilities and limitations of risk assessment, respectively, might impair decision-making by the relevant regulatory authorities and research ethics committees, and discuss possible solutions to tackle the issue.

Service Level Decision-making in Rural Physiotherapy: Development of Conceptual Models.

Understanding decision-making about health service provision is increasingly important in an environment of increasing demand and constrained resources. Multiple factors are likely to influence decisions about which services will be provided, yet workforce is the most noted factor in the rural physiotherapy literature. This paper draws together results obtained from exploration of service level decision-making (SLDM) to propose 'conceptual' models of rural physiotherapy SLDM. A prioritized qualitative approach enabled exploration of participant perspectives about rural physiotherapy decision-making. Stakeholder perspectives were obtained through surveys and in-depth interviews. Interviews were transcribed verbatim and reviewed by participants. Participant confidentiality was maintained by coding both participants and sites. A system theory-case study heuristic provided a framework for exploration across sites within the investigation area: a large area of one Australian state with a mix of regional, rural and remote communities. Thirty-nine surveys were received from participants in 11 communities. Nineteen in-depth interviews were conducted with physiotherapists and key decision-makers. Results reveal the complexity of factors influencing rural physiotherapy service provision and the value of a systems approach when exploring decision-making about rural physiotherapy service provision. Six key features were identified that formed the rural physiotherapy SLDM system: capacity and capability; contextual influences; layered decision-making; access issues; value and beliefs; and tensions and conflict. Rural physiotherapy SLDM is not a one-dimensional process but results from the complex interaction of clusters of systems issues. Decision-making about physiotherapy service provision is influenced by both internal and external factors. Similarities in influencing factors and the iterative nature of decision-making emerged, which enabled linking physiotherapy SLDM with clinical decision-making and placing both within the broader healthcare context. The conceptual models provide a way of thinking about decisions informing rural physiotherapy service provision. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Thibault, Alexis

2015-01-01

In the context of the fiftieth anniversary celebrations of the Département de psychiatrie de l'Université de Montréal, the present article offers to retrace the history of the Psychiatry Resident's Association (ARPUM). Since the Association's activities and demands reflected the concerns of the time, a depiction of the Residency Program and exploration of the historical and administrative context, in each key period, is also undertaken. Multiple psychiatrists from every decade, who were once active members of the Association, were interviewed and asked to describe the Residency Program at their time, with its positive and negative aspects, based on their own personal experience as a resident, but also as a member of the organization. The interviewees were also invited to share their recollections of the various Association's demands, representations, activities and functioning, depending on the issues and periods. Various private and public archives were also used, in order to contextualize the residents' experiences and the Association's work. A brief exploration of the historical and political context that led to the creation of the organization is explained. Training and working conditions of residents at that time are reported, enabling the understanding of the first demands when the group was born. Historical jumps are then proposed, from decades to decades, in order to depict key issues, whether they were academic, clinical or organizational, through which the Association worked, over the evolution of the Residency Program. The internal functioning and its occasional problems throughout the years are also described, as is the role in organizing social and educational events. The Residency Program is in constant mutation, and the Association has played its part in shaping the psychiatric training at the Université de Montréal. Multiple positive and tangible impacts were and are still made possible from the collaborative work between the Département de psychiatrie, the Residency Program and the Resident's Association.

Prosody and informativity: A cross-linguistic investigation

NASA Astrophysics Data System (ADS)

Ouyang, Iris Chuoying

This dissertation aims to extend our knowledge of prosody -- in particular, what kinds of information may be conveyed through prosody, which prosodic dimensions may be used to convey them, and how individual speakers differ from one another in how they use prosody. Four production studies were conducted to examine how various factors interact with one another in shaping the prosody of an utterance and how prosody fulfills its multi-functional role. Experiments 1 explores the interaction between two types of informativity, namely information structure and information-theoretic properties. The results show that the prosodic consequences of new-information focus are modulated by the focused word's frequency, whereas the prosodic consequences of corrective focus are modulated by the focused word's probability in the context. Furthermore, f0 ranges appear to be more informative than f0 shapes in reflecting informativity across speakers. Specifically, speakers seem to have individual 'preferences' regarding f0 shapes, the f0 ranges they use for an utterance, and the magnitude of differences in f0 ranges by which they mark information-structural distinctions. In contrast, there is more cross-speaker validity in the actual directions of differences in f0 ranges between information-structural types. Experiments 2 and 3 further show that the interaction found between corrective focus and contextual probability depends on the interlocutor's knowledge state. When the interlocutor has no access to the crucial information concerning utterances' contextual probability, speakers prosodically emphasize contextually improbable corrections, but not contextually probable corrections. Furthermore, speakers prosodically emphasize the corrections in response to contextually probable misstatements, but not the corrections in response to contextually improbable misstatements. In contrast, completely opposite patterns are found when words' contextual probability is shared knowledge between the speaker and the interlocutor: speakers prosodically emphasize contextually probable corrections and the corrections in response to contextually improbable misstatements. Experiment 4 demonstrates the multi-functionality of prosody by investigating its discourse-level functions in Mandarin Chinese, a tone language where a word's prosodic patterns is crucial to its meaning. The results show that, although prosody serves fundamental, lexical-level functions in Mandarin Chinese, it nevertheless provides cues to information structure as well. Similar to what has been found with English, corrective information is prosodically more prominent than non-corrective information, and new information is prosodically more prominent than given information. Taken together, these experiments demonstrate the complex relationship between prosody and the different types of information it encodes in a given language. To better understand prosody, it is important to integrate insights from different traditions of research and to investigate across languages. In addition, the findings of this research suggest that speakers' assumptions about what their interlocutors know -- as well as speakers' ability to update these expectations -- play a key role in shaping the prosody of utterances. I hypothesize that prosodic prominence may reflect the gap between what speakers had expected their interlocutors to say and what their interlocutors have actually said.

The aim of this paper was to identify the key factors of case management (CM) interventions among frequent users of healthcare services found in empirical studies of effectiveness. Thematic analysis review of CM studies. We built on a previously published review that aimed to report the effectiveness of CM interventions for frequent users of healthcare services, using the Medline, Scopus and CINAHL databases covering the January 2004-December 2015 period, then updated to July 2017, with the keywords 'CM' and 'frequent use'. We extracted factors of successful (n=7) and unsuccessful (n=6) CM interventions and conducted a mixed thematic analysis to synthesise findings. Chaudoir's implementation of health innovations framework was used to organise results into four broad levels of factors: (1) ,environmental/organisational level, (2) practitioner level, (3) patient level and (4) programme level. Access to, and close partnerships with, healthcare providers and community services resources were key factors of successful CM interventions that should target patients with the greatest needs and promote frequent contacts with the healthcare team. The selection and training of the case manager was also an important factor to foster patient engagement in CM. Coordination of care, self-management support and assistance with care navigation were key CM activities. The main issues reported by unsuccessful CM interventions were problems with case finding or lack of care integration. CM interventions for frequent users of healthcare services should ensure adequate case finding processes, rigorous selection and training of the case manager, sufficient intensity of the intervention, as well as good care integration among all partners. Other studies could further evaluate the influence of contextual factors on intervention impacts. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To engage a community to critically examine local health disparities. Concept mapping is a tool used to rapidly assess the variations in thinking of large stakeholder groups' about a particular topic. Jackson, Mississippi. Community members. Dialog groups and community meetings were held, and participants were asked to respond to the statement, "A specific thing that causes African Americans to get sicker and die sooner is..." Aggregate responses were rated for importance and feasibility and then sorted into related groups. Aggregate sorts and ratings were then processed by using multidimensional scaling and hierarchical cluster analysis. There were 132 (unduplicated) reported contributors to health disparities. These responses fell into eight general clusters: economic issues, government, contextual factors, cultural factors, HIV, stress, environment, and motivation. Factors respondents felt were the most important contributors to disparities (economic factors, contextual factors, stress) did not correlate with those that they thought were most likely to be changed in society (contextual factors, government, motivation). Concept mapping provided a mechanism for rapidly documenting community thinking about health disparities. This mechanism stimulated community dialog and was used as a first step toward the long-term goal of creating equal community, academic, and medical partnerships for addressing disparities. The concept mapping process stimulated critical thinking about contributors to health inequities and uncovered contextual factors previously unknown to researchers and public health planners. The process allowed for active engagement and exchange of knowledge between the community and researchers and allowed a mechanism for identifying and rectifying disconnects in knowledge within and between stakeholder groups.

Acceptance of lean redesigns in primary care: A contextual analysis.

PubMed

Hung, Dorothy; Gray, Caroline; Martinez, Meghan; Schmittdiel, Julie; Harrison, Michael I

Lean is a leading change strategy used in health care to achieve short-term efficiency and quality improvement while promising longer-term system transformation. Most research examines Lean intervention to address isolated problems, rather than to achieve broader systemic changes to care delivery. Moreover, no studies examine contextual influences on system-wide Lean implementation efforts in primary care. The aim of this study was to identify contextual factors most critical to implementing and scaling Lean redesigns across all primary care clinics in a large, ambulatory care delivery system. Over 100 interviews and focus groups were conducted with frontline physicians, clinical staff, and operational leaders. Data analysis was guided by a modified Consolidated Framework for Implementation Research (CFIR), a popular implementation science framework. On the basis of expert recommendations, the modified framework targets factors influencing the implementation of process redesigns. This modified framework, the CFIR-PR, informed our identification of contextual factors that most impacted Lean acceptance among frontline physicians and staff. Several domains identified by the CFIR-PR were critical to acceptance of Lean redesigns. Regarding the implementation process acceptance was influenced by time and intensity of exposure to changes, "top-down" versus "bottom-up" implementation styles, and degrees of employee engagement in developing new workflows. Important factors in the inner setting were the clinic's culture and style of leadership, along with availability of information about Lean's effectiveness. Last, implementation efforts were impacted by individual and team characteristics regarding changed work roles and related issues of professional identity, authority, and autonomy. This study underscores the need for change leaders to consider the contextual factors that surround efforts to implement Lean in primary care. As Lean redesigns are scaled across a system, special attention is warranted with respect to the implementation approach, internal clinic setting, and implications for professional roles and identities of physicians and staff.

Privacy-Preserving Predictive Modeling: Harmonization of Contextual Embeddings From Different Sources.

Data sharing has been a big challenge in biomedical informatics because of privacy concerns. Contextual embedding models have demonstrated a very strong representative capability to describe medical concepts (and their context), and they have shown promise as an alternative way to support deep-learning applications without the need to disclose original data. However, contextual embedding models acquired from individual hospitals cannot be directly combined because their embedding spaces are different, and naive pooling renders combined embeddings useless. The aim of this study was to present a novel approach to address these issues and to promote sharing representation without sharing data. Without sacrificing privacy, we also aimed to build a global model from representations learned from local private data and synchronize information from multiple sources. We propose a methodology that harmonizes different local contextual embeddings into a global model. We used Word2Vec to generate contextual embeddings from each source and Procrustes to fuse different vector models into one common space by using a list of corresponding pairs as anchor points. We performed prediction analysis with harmonized embeddings. We used sequential medical events extracted from the Medical Information Mart for Intensive Care III database to evaluate the proposed methodology in predicting the next likely diagnosis of a new patient using either structured data or unstructured data. Under different experimental scenarios, we confirmed that the global model built from harmonized local models achieves a more accurate prediction than local models and global models built from naive pooling. Such aggregation of local models using our unique harmonization can serve as the proxy for a global model, combining information from a wide range of institutions and information sources. It allows information unique to a certain hospital to become available to other sites, increasing the fluidity of information flow in health care. ©Yingxiang Huang, Junghye Lee, Shuang Wang, Jimeng Sun, Hongfang Liu, Xiaoqian Jiang.

Human resource processes and the role of the human resources function during mergers and acquisitions in the electricity industry

NASA Astrophysics Data System (ADS)

Dass, Ted K.

Mergers and acquisitions (M&A) have been a popular strategy for organizations to consolidate and grow for more than a century. However, research in this field indicates that M&A are more likely to fail than succeed, with failure rates estimated to be as high as 75%. People-related issues have been identified as important causes for the high failure rate, but these issues are largely neglected until after the deal is closed. One explanation for this neglect is the low involvement of human resource (HR) professionals and the HR function during the M&A process. The strategic HR management literature suggests that a larger role for HR professionals in the M&A process would enable organizations to identify potential problems early and devise appropriate solutions. However, empirical research from an HR perspective has been scarce in this area. This dissertation examines the role of the HR function and the HR processes followed in organizations during M&A. Employing a case-study research design, this study examines M&A undertaken by two large organizations in the electricity industry through the lens of a "process" perspective. Based on converging evidence, the case studies address three sets of related issues: (1) how do organizations undertake and manage M&A; (2) what is the extent of HR involvement in M&A and what role does it play in the M&A process; and (3) what factors explain HR involvement in the M&A process and, more generally, in the formulation of corporate goals and strategies. Results reveal the complexity of issues faced by organizations in undertaking M&A, the variety of roles played by HR professionals, and the importance of several key contextual factors---internal and external to the organization---that influence HR involvement in the M&A process. Further, several implications for practice and future research are explored.

Building a More Diverse Workforce in HIV/AIDS Research: The Time has Come.

Investigators from diverse racial and ethnic backgrounds are grossly underrepresented in the nation's biomedical research enterprise. Projections of current demographic trends suggest that population growth rates of minority populations will outpace that of the Caucasian population by 2060. Thus, this workforce will remain a poor reflection of the U.S. As a result of this underrepresentation of all sectors of the U.S. populace, the majority of the HIV research involving minority populations-those disproportionately impacted by HIV infection-will be conducted by investigators who do not resemble them. Although this does not necessarily preclude scientifically valid and important research, it produces research without the important cultural and contextual issues that can enhance the utility and generalizability of specific findings or interventions. The goal of this review is to not only raise awareness of the small numbers of minority investigators engaged in biomedical research, but also to identify the challenges to recruiting and retaining these investigators. In this article, while we discuss issues of diversity in general, the focus will be upon the mental health aspects of the HIV epidemic for illustrative purposes: to demonstrate the issues associated with enhancing investigator diversity as a strategy for remediating the chronic shortage of historically underrepresented investigators in scientific research. After presenting the magnitude of the problem and a rationale for enhancing diversity of the biomedical research workforce, we identify a number of potential reasons and challenges for the shortage of minority investigators. Aspects of the mentoring process, together with ten key suggestions, are discussed as the backdrop for the supplement papers that follow (dealing with mentoring principles, challenges, and mentoring-related issues on mentee, mentor, mentee-mentor relationship, and programs). By identifying these realities we hope to: (1) promote greater discussions of these challenges in academic institutions and settings; (2) suggest meaningful strategies to address these challenges; and (3) foster a national discussion about the long-term investment necessary for permanent change, as there are no easy 'fixes' for these challenges.

India’s Distorted Sex Ratio: Dire Consequences for Girls

Female gender discrimination related to cultural preference for males is a common global problem, especially in Asian countries. Numerous laws intended to prevent discrimination on the basis of gender have been passed in India, yet the distorted female-to-male sex ratio seems to show worsening tendencies. Using detailed, two-year longitudinal chart abstraction data about delivery records of a private mission hospital in rural India, we explored if hospital birth ratio data differed in comparison to regional data, and what demographic and contextual variables may have influenced these outcomes. Using quantitative chart abstraction and qualitative contextual data, study results showed the female-to-male ratio was lower than the reported state ratio at birth. In the context of India’s patriarchal structure, with its strong son preference, women are under tremendous pressure or coerced to access community-based, sex-selective identification and female fetus abortion. Nurses may be key to turning the tide. PMID:28286369

Children's strategies to solving additive inverse problems: a preliminary analysis

Prior studies show that elementary school children generally "lack" formal understanding of inverse relations. This study goes beyond lack to explore what children might "have" in their existing conception. A total of 281 students, kindergarten to third grade, were recruited to respond to a questionnaire that involved both contextual and non-contextual tasks on inverse relations, requiring both computational and explanatory skills. Results showed that children demonstrated better performance in computation than explanation. However, many students' explanations indicated that they did not necessarily utilize inverse relations for computation. Rather, they appeared to possess partial understanding, as evidenced by their use of part-whole structure, which is a key to understanding inverse relations. A close inspection of children's solution strategies further revealed that the sophistication of children's conception of part-whole structure varied in representation use and unknown quantity recognition, which suggests rich opportunities to develop students' understanding of inverse relations in lower elementary classrooms.

Evidence-informed policymaking has been promoted as a means of ensuring better outcomes. However, what counts as evidence in policymaking lies within a spectrum of expert knowledge and scientifically generated information. Since not all forms of evidence share an equal validity or weighting for policymakers, it is important to understand the key factors that influence their preferences for different types of evidence in policy and strategy development. A retrospective study was carried out at the national level in Nigeria using a case-study approach to examine the Nigerian Integrated Maternal Newborn and Child Health (IMNCH) strategy. Two frameworks were used for conceptualization and data analysis, namely (1) to analyse the role of evidence in policymaking and (2) the policy triangle. They were used to explore the key contextual and participatory influences on choice of evidence in developing the IMNCH strategy. Data was collected through review of relevant national documents and in-depth interviews of purposively selected key policy and strategic decision makers. Thematic analysis was applied to generate information from collected data. The breadth of evidence used was wide, ranging from expert opinions to systematic reviews. The choice of different types of evidence was found to overlap across actor categories. Key influences over actors' choice of evidence were: (1) perceived robustness of evidence - comprehensive, representative, recent, scientifically sound; (2) roles in evidence process, i.e. their degree and level of participation in evidence generation and dissemination, with regards to their role in the policy process; and (3) contextual factors such as global agenda and influence, timeline for strategy development, availability of resources for evidence generation, and lessons learnt from previous unsuccessful policies/plans. Actors' preferences for different types of evidence for policy are influenced not only by the characteristics of evidence itself, but on actors' roles in the evidence process, their power to influence the policy, and the context in which evidence is used.

Contextualizing group rape in post-apartheid South Africa.

Collective male sexual violence is part of a continuum of sexual coercion in South Africa. This paper is based on long-term ethnographic work in an urban township in the former Transkei region. Drawing on intensive participant observation and interviews with young men in particular, it attempts to make sense of emergent narratives relating to streamlining, a local term for a not uncommon form of collective sexual coercion involving a group of male friends and one or more women. The paper begins with an overview of existing anthropological literature on collective male sexual violence, going onto elaborate the different scenarios associated with group sexual violence in the fieldsite. It seeks to provide a multi-layered contextualization of the phenomenon by considering prevailing gender discourses, subcultural issues pertaining to the urban tsotsi phenomenon, the rural practice of ukuthwala (bride capture), young working-class Africans' experiences of marginalization, and the complex links between political economy and violence in this setting.
