The purpose of this study is to analyze the relationship between home modifications and aging-in-place. Using the ENABLE-AGE United Kingdom sample (N = 376), the authors hypothesize that seniors who have modified their housing are likely to have stayed longer in their current housing. There is a positive relationship between home modifications and aging-in-place. The results underscore the importance of supportive environment to prolong living in housing settings.  相似文献

This paper introduces a new model to represent how individuals can develop a deepened understanding of both a foreign culture and of their own culture as a result of viewing and engaging with foreign media, and in particular foreign films and television series. The model emerged from data collected in a study of how Chinese university students based in China make sense of films and television series produced in the USA and the UK. The study involved a series of semi-structured interviews during which the students were shown clips from a number of films and television series. Five categories of sense-making activities emerged from the data, together with a number of variables, which influenced the activities, and a number of levels on which the activities could be performed. The proposed model captures all of these aspects.  相似文献

Since the 1980s, much has been written about the importance of including women in environmental decision making. However, when and how women are included remains an issue. The goal of this article was to explore how the historical exclusion of women from the production of conservation visual narratives continues to have an influence on conservation networks. We surveyed 121 National Geographic Society-affiliated conservation/wildlife photographers, which produced a usable sample of 98 photographers, to assess whether there is evidence of the historical legacy of female exclusion in contemporary elite conservation photography networks. Using network analysis, we find a strong network among 67 conservation photographers, with eight subgroups. Our analysis shows that there are formal networks among conservation photographers, but these networks are sparsely populated with women. Of the women who are present, they mostly engage in the same subnetworks. Our findings provide evidence to support the notion that the historical exclusion of women from the production of visual conservation narratives has had a lasting impact on the network of conservation image producers, which may influence the way conservation is depicted to the general public. We situate our findings using gendered organizational theory.  相似文献

This article introduces a new integrated scenario-based evacuation (ISE) framework to support hurricane evacuation decision making. It explicitly captures the dynamics, uncertainty, and human–natural system interactions that are fundamental to the challenge of hurricane evacuation, but have not been fully captured in previous formal evacuation models. The hazard is represented with an ensemble of probabilistic scenarios, population behavior with a dynamic decision model, and traffic with a dynamic user equilibrium model. The components are integrated in a multistage stochastic programming model that minimizes risk and travel times to provide a tree of evacuation order recommendations and an evaluation of the risk and travel time performance for that solution. The ISE framework recommendations offer an advance in the state of the art because they: (1) are based on an integrated hazard assessment (designed to ultimately include inland flooding), (2) explicitly balance the sometimes competing objectives of minimizing risk and minimizing travel time, (3) offer a well-hedged solution that is robust under the range of ways the hurricane might evolve, and (4) leverage the substantial value of increasing information (or decreasing degree of uncertainty) over the course of a hurricane event. A case study for Hurricane Isabel (2003) in eastern North Carolina is presented to demonstrate how the framework is applied, the type of results it can provide, and how it compares to available methods of a single scenario deterministic analysis and a two-stage stochastic program.  相似文献

ABSTRACT

The shifting demographics that come with migration and globalization have changed the settings for social work education in Sweden. To promote sustainability in a diverse society, strategies for inclusion and equality are essential in the development of core competencies in social work. One essential question is how social work education has responded to the demographic changes. The study aims to contribute with knowledge about how ethnicity is conceptualized in Sweden and to describe the impact the subject has on teaching forms and strategies. More specifically, the study investigates university teachers’ expressions of their teaching practices about the concept and addresses the faculty members’ narratives about the teaching situations. The study concludes that the lack of a coherent academic context for teaching ethnicity leads to the development of individual approaches by the teachers and a personalization of the issue of ethnicity in social work education. This creates a limitation on how structural elements come into play in relation to ethnicity, and in turn, leads to a shortage of a critical analysis of the construction of social problems where ethnicity plays a fundamental role. These circumstances precede theoretical perspectives on social problems related to ethnicity, migration, transnational relations, globalization, and racism.  相似文献

Functional neurological symptom disorder, alternatively termed conversion disorder (FNSD-CD) (Although the DSM-5 utilises the term 'conversion disorder', practitioners and consumers consider this to be an outdated, unsubstantiated and often stigmatising term. In accordance with this, the current terminology used in the field is 'functional neurological symptom disorder'), involves symptoms of altered voluntary motor or sensory functions without identifiable nervous system disease or pathology. It is considered a psychiatric disorder and is, thus, listed in the Diagnostic and Statistical Manual of Mental Disorders (5th Ed.; DSM-5). As per the nosology of the DSM-5, the discrete behavioural or psychological syndrome or pattern observed in FNSD-CD is assumed to be a function of a problem of, or a disorder within, the individual. Accordingly, the psychiatric approach to FNSD-CD, as set out in the DSM-5, invokes an assumption common to the medical model which is that of lineal (i.e., straight-line) causality, namely, causal events are arranged in a lineal sequence. The interactional approach, however, which is a development of general system theory in the field of family therapy, offers an alternative approach to understanding psychiatric disorders. Specifically, this approach places the emphasis on the relationships between individuals and their reciprocal influences on – including their psychological and emotional wellbeing with – one another. It draws on the assumption of nonlineal (i.e., circular) causality, namely, causal events are arranged in a circular sequence. From an interactional approach, therefore, FNSD-CD is thought to be a function of a problem of, or a deficit within, the individuals’ relationship/s, rather than within an individual, per se. This article utilises a composite case study to investigate FNSD-CD from an interactional approach.  相似文献

Fisher's exact test, difference in proportions, log odds ratio, Pearson's chi-squared, and likelihood ratio are compared as test statistics for testing independence of two dichotomous factors when the associated p values are computed by using the conditional distribution given the marginals. The statistics listed above that can be used for a one-sided alternative give identical p values. For a two-sided alternative, many of the above statistics lead to different p values. The p values are shown to differ only by which tables in the opposite tail from the observed table are considered more extreme than the observed table.  相似文献

We review approaches for characterizing “peak” exposures in epidemiologic studies and methods for incorporating peak exposure metrics in dose–response assessments that contribute to risk assessment. The focus was on potential etiologic relations between environmental chemical exposures and cancer risks. We searched the epidemiologic literature on environmental chemicals classified as carcinogens in which cancer risks were described in relation to “peak” exposures. These articles were evaluated to identify some of the challenges associated with defining and describing cancer risks in relation to peak exposures. We found that definitions of peak exposure varied considerably across studies. Of nine chemical agents included in our review of peak exposure, six had epidemiologic data used by the U.S. Environmental Protection Agency (US EPA) in dose–response assessments to derive inhalation unit risk values. These were benzene, formaldehyde, styrene, trichloroethylene, acrylonitrile, and ethylene oxide. All derived unit risks relied on cumulative exposure for dose–response estimation and none, to our knowledge, considered peak exposure metrics. This is not surprising, given the historical linear no‐threshold default model (generally based on cumulative exposure) used in regulatory risk assessments. With newly proposed US EPA rule language, fuller consideration of alternative exposure and dose–response metrics will be supported. “Peak” exposure has not been consistently defined and rarely has been evaluated in epidemiologic studies of cancer risks. We recommend developing uniform definitions of “peak” exposure to facilitate fuller evaluation of dose response for environmental chemicals and cancer risks, especially where mechanistic understanding indicates that the dose response is unlikely linear and that short‐term high‐intensity exposures increase risk.  相似文献
