In any crisis, there is a great deal of uncertainty, often geographical uncertainty or, more precisely, spatiotemporal uncertainty. Examples include the spread of contamination from an industrial accident, drifting volcanic ash, and the path of a hurricane. Estimating spatiotemporal probabilities is usually a difficult task, but that is not our primary concern. Rather, we ask how analysts can communicate spatiotemporal uncertainty to those handling the crisis. We comment on the somewhat limited literature on the representation of spatial uncertainty on maps. We note that many cognitive issues arise and that the potential for confusion is high. We note that in the early stages of handling a crisis, the uncertainties involved may be deep, i.e., difficult or impossible to quantify in the time available. In such circumstance, we suggest the idea of presenting multiple scenarios.  相似文献

句法角色与话题性都会影响语篇实体的突显性程度。采用汉语续写实验,将实验句置于语境之中,在句法角色恒定条件下操控话题性和指称形式等变量,可探察实体作为语篇话题和非话题在续写时的表征趋势,即重述形式。实验发现,在续写初期,话题性不能影响实体的重述,它与句法角色之间无交互作用|在续写后期,话题性确实对实体重述起到一定作用。此外,目标句给定指称形式虽然不影响实体重述,但在一定条件下会影响被试对重述形式的选择。  相似文献

Recent work within early executive function (EF) seems to suggest that toddlers show distinct patterns of development, involving poorly correlated performance across EF tasks and significant improvements over relatively short periods of time. The present study sought to extend these findings by investigating evidence for these patterns in toddlers and the existence of more traditional patterns of EF (e.g., correlations between tasks, links to language) when using the same tasks in a novel Latin American sample. Eighty toddlers (18–24 months) and sixty young preschoolers (30–36) months completed a battery of EF tasks, early social communication, and receptive and expressive language measures. Results indicated that toddlers showed similar distinct patterns of development (i.e., few relations between tasks and links to responding to joint attention), but by early preschool a more cohesive EF and links to language were present. Further, work demonstrated significant age (older children outperformed younger children), gender (girls outperformed boys), and socioeconomic differences (satisfied basic needs outperformed unsatisfied basic needs, but only on the snack delay). This work provides evidence for patterns of emerging EF development within this novel cultural sample (and evidence for group differences) that may be supported by communicative and representational development.  相似文献

The difficulties associated with conducting valid family therapy research within a clinical practice discourage many potential researchers. This article will describe collaboration between a group of academics, researchers and clinicians who decided to explore the process and efficacy of systemic family therapy conducted within a working private practice. The specific questions we are addressing are, whether the requests clients bring to their first session of therapy can be reliably classified by practitioners, whether these requests change over time, and whether the nature of the request is associated with therapist and client ratings of therapeutic outcome. Additional questions about the form and nature of the therapeutic alliance as experienced by both client and practitioner are also being explored. This paper will map the passage of the work from inception to its current state where over 140 clients are active participants. In doing so attention will be paid to the obstacles encountered: practical, financial and ethical, and the solutions devised to address these.  相似文献

The purpose of this study was to examine the relation between family interaction quality of married elderly and their offspring and life satisfaction of older persons. Information was obtained by means of mailed questionnaires completed by both spouses of 68 married, retired couples living in Georgia and North Carolina who were identified through churches, senior centers, and congregate housing units and through personal contacts. For the total sample, health status was the strongest predictor of life satisfaction followed by certain family strengths factors and job prestige, respectively. Males and females differed concerning which variables contributed most to explaining variance in life satisfaction. Variance in life satisfaction of males was best explained by job prestige, family strengths, and financial help given. Variance in life satisfaction of women was best explained by their perception of their health, family strengths, and job prestige.  相似文献

We argue that regional comparison of East Asian and European ethnic return migration policy offers important new perspectives on nationhood, nondiscrimination norms, and trans‐nationality. We find that despite international nondiscrimination norms, preferential ethnic return policy is common in both regions. These policies at least implicitly define the nation as existing across borders. However, there are significant regional differences. East Asian states use co‐ethnic preferences instrumentally for economic goals and also offer preferential treatment of co‐ethnic foreign investors. European states offer preferences to coethnics to protect these populations or express symbolic ties, sometimes at great expense. Thus, in Europe the state has an obligation to assist coethnics abroad, but in Asia, foreign coethnics assist the state.  相似文献

This study examines the extent to which professional credentials accrued during graduate school are related to postgraduate employment. The undergraduate and graduate records, demographic characteristics, and initial job placements of 711 Ph.D. recipients from the University of California, Santa Barbara, are analyzed. We find that several aspects of graduate training (e.g., holding research assistantships) have greater influence on the initial placement of women than men. Further, coauthored publications with the mentor influence the initial placement of men and women somewhat differently. Given the importance of initial placement in determining career productivity (e.g., Long and McGinnis, 1981; Reskin, 1978). these differences may have considerable impact on professional life chances.  相似文献
