A hierarchical needs assessment model used to identify the competencies required by communication management practitioners in the New Zealand workplace generated three key findings. First, there was evidence of a perspective of CM as a distinct discipline founded on an agreed body of knowledge, skills and values. Second, despite an identified lack of consensus about required CM competencies in the literature, we found high levels of agreement between practitioners and academics. Third, there was, however, a significant difference in views between these two groups about the importance of the competency managing client reputation. As this was rated as one of the two most important competencies by respondents, there are implications for changing the focus of tertiary curricula to ensure graduates are appropriately prepared for the reality of workplace practice. 相似文献

The value of the continuing education industry for therapists is questioned, as is the usefulness of therapy books and journal articles, as a means of engaging therapists in life‐long learning. Instead, it is argued that our clients are our best teachers and that therapists learn most effectively from their clients. Drawing on research studies with prominent theoreticians and therapists, and on case studies from clinical work, a number of important themes are identified as ways in which therapists are influenced by their therapeutic encounters with their clients. The themes explored in this article include: (1) intimacy and high emotional arousal with clients as we witness profound change; (2) being challenged by clients; and (3) allowing for boundary ‘crossings’ in order to develop more flexible ways of working with clients. The implications for professional development are discussed. 相似文献

Although most students graduate from high school and enroll in college the following fall, rates of entry into higher education and completion of a bachelor's degree continue to be stratified by race and class. Because of the potential returns that accrue to individuals and society overall when students complete their 4‐year degree, these disparate trends should motivate more policy‐relevant research in this area. In this review, I show how a longitudinal perspective of the path to a BA degree helps to reconcile competing theories of college completion by race and class across disciplinary boundaries. Both human capital theory and status attainment theory largely examine college completion as the long‐term process of BA attainment, although they differ in their focal stages and mechanisms. In contrast, the theory of categorical inequality, as applied in this review, focuses on the years in higher education and describes the ways in which colleges and universities as organizations create, legitimate, and reinforce categorical distinctions in postsecondary schooling and how these processes independently shape college completion inequality. As public interest grows in holding colleges accountable for their graduation rates, more research is needed on how the formal and informal organizational policies and practices of colleges produce inequality. 相似文献

Many common decision-making situations require integration of a number of objectives or goals into a single objective function to be optimized. A number of techniques for performing this analysis are presented in the literature. These procedures generally require a tradeoff between realism and tractability. The present approach uses the idea of preemptive priority levels with an approximate value function at each level. An efficient experimental design is used to assess directly a quadratic approximation of the multiattribute value functions. An existing algorithm is then used to solve the resulting problem. This procedure is shown to give good results when compared to both the value-function method and goal programming. 相似文献

This article explores the career dynamics of performers in the gay male pornography industry, by focusing on a common career path- from porn star to stripper to escort. Between 1995 and 2005, most men performing in gay porn films, unlike contract actresses in the straight porn industry, have been unable to earn enough income to work exclusively as performers in front of the camera. The industry's constant search for new faces and fresh performers creates what sociologist Paul Cressey has called "the retrogressive dynamic": The longer a person works in a sexual occupation, the less one is paid, and the lower the status of the work venue. In the porn industry, one aspect of this process is referred to as "overexposure," during which the performer experiences a diminishing "fantasy potential" as fans lose erotic interest in the porn star who has appeared too frequently in too many movies. Performers attempt to confront the retrogressive dynamic by limiting the number of adult films in which they appear in a year, diversifying their sexual repertoire, or shifting into other roles within the industry (behind the camera, marketing, production, etc.). One common option is to pursue work in economically complementary forms of sex work such as stripping and escorting. 相似文献

Toxoplasma gondii is a protozoan parasite that is responsible for approximately 24% of deaths attributed to foodborne pathogens in the United States. It is thought that a substantial portion of human T. gondii infections is acquired through the consumption of meats. The dose‐response relationship for human exposures to T. gondii‐infected meat is unknown because no human data are available. The goal of this study was to develop and validate dose‐response models based on animal studies, and to compute scaling factors so that animal‐derived models can predict T. gondii infection in humans. Relevant studies in literature were collected and appropriate studies were selected based on animal species, stage, genotype of T. gondii, and route of infection. Data were pooled and fitted to four sigmoidal‐shaped mathematical models, and model parameters were estimated using maximum likelihood estimation. Data from a mouse study were selected to develop the dose‐response relationship. Exponential and beta‐Poisson models, which predicted similar responses, were selected as reasonable dose‐response models based on their simplicity, biological plausibility, and goodness fit. A confidence interval of the parameter was determined by constructing 10,000 bootstrap samples. Scaling factors were computed by matching the predicted infection cases with the epidemiological data. Mouse‐derived models were validated against data for the dose‐infection relationship in rats. A human dose‐response model was developed as P (d) = 1–exp (–0.0015 × 0.005 × d) or P (d) = 1–(1 + d × 0.003 / 582.414)?1.479. Both models predict the human response after consuming T. gondii‐infected meats, and provide an enhanced risk characterization in a quantitative microbial risk assessment model for this pathogen. 相似文献

一直以来,对文化的社会研究不是被极端化为结构主义理论就是被极端化为实用主义理论,前者视意义为文本并注重探索提供相对自主性的模式,后者则将意义处理为由个人或集体行动之权变性的创发--即所谓的实践本身,并将文化模式作为权力和物质利益之反应加以分析。在本文中,我将阐述一个超越这种极化视野的文化语用学理论,以新的方式将意义结构、权变性、权力和物质性融为一体。我的论点是,实践的物质性可以由维度更多的表演概念所取代。通过对表演研究这一新领域的成果的吸收,文化语用学说明社会表演,无论个人还是集体的,是如何可能被系统地类推为剧场表演的。在定义了社会表演的要素之后,我认为,随着社会变得更加复杂,这些要素已经趋于“分解”(de fused)。只有在能够将这些日渐离析的要素“再融合”的情况下,表演才会成功。在融合化的表演中,观众认同演员,且文化剧本通过有效的舞台布景达到逼真的程度。而当诸要素重新连接的过程并不完美时,表演就会失败:表演要素仍处于分离状态,社会行动看上去不但不够本真(authentic),而且显得造作和难以令人信服。与此相对,再融合能使演员成功地传达其行动的意义并有效地实现他们的利益。 相似文献

This study explored how older workers (age 55+) differed from middle-aged (ages 35–54) and young workers (<35 years) in their experience of the work–family interface. Data came from a subset of a survey conducted by a multi-national corporation in 79 countries (N = 41,813, n = 2,700). Older workers reported significantly less work-to-family and family-to-work conflict and greater work–family fit, life success, and work success than middle-aged and young workers. They reported significantly greater job flexibility and job satisfaction but were significantly less likely to be aware of and use work–family programs than young workers. Older men reported significantly less awareness and use of work-life programs and less family-to-work conflict than older women. Implications of this research are presented. 相似文献

Protective actions for hurricane threats are a function of the environmental and information context; individual and household characteristics, including cultural worldviews, past hurricane experiences, and risk perceptions; and motivations and barriers to actions. Using survey data from the Miami‐Dade and Houston‐Galveston areas, we regress individuals’ stated evacuation intentions on these factors in two information conditions: (1) seeing a forecast that a hurricane will hit one's area, and (2) receiving an evacuation order. In both information conditions having an evacuation plan, wanting to keep one's family safe, and viewing one's home as vulnerable to wind damage predict increased evacuation intentions. Some predictors of evacuation intentions differ between locations; for example, Florida respondents with more egalitarian worldviews are more likely to evacuate under both information conditions, and Florida respondents with more individualist worldviews are less likely to evacuate under an evacuation order, but worldview was not significantly associated with evacuation intention for Texas respondents. Differences by information condition also emerge, including: (1) evacuation intentions decrease with age in the evacuation order condition but increase with age in the saw forecast condition, and (2) evacuation intention in the evacuation order condition increases among those who rely on public sources of information on hurricane threats, whereas in the saw forecast condition evacuation intention increases among those who rely on personal sources. Results reinforce the value of focusing hurricane information efforts on evacuation plans and residential vulnerability and suggest avenues for future research on how hurricane contexts shape decision making. 相似文献
