ABSTRACT: Many of the suicide prevention centers that developed throughout the country during the last decade have evolved into general crisis intervention services. At the same time, they have stimulated the development of a wide variety of agencies that utilize nonprofessional volunteers who, primarily through telephone contact, provide helping services to people in crisis. This paper presents a critique of three particular problem areas relating to the use of volunteer personnel, along with a summary of research aimed at providing new technologies for their solution. Methods have been developed for rating on-the-job performance of crisis intervention workers, based upon criteria that are thought to have general application to crisis intervention centers. Efforts to describe personality characteristics of volunteers are reported, along with suggestions for the direction of additional investigations. Finally, the issue of assessing the outcome of crisis intervention cases is summarized. A four-phase conceptualization of the crisis intervention process is proposed, and appropriate measures of outcome at each point in the process are suggested. The overall significance of this type of research is discussed in terms of the need for standards by which to evaluate crisis intervention services. 相似文献

ABSTRACTIn this mixed methods study of 56 entry-level pimps in Harlem, NY, we explore how pimps’ choices to use violence or control differ by where they are selling sex, who their clientele are, and whether these violent and controlling behaviors yield higher returns. First, we qualitatively explore how pimps account for each of these choices, and how each group of choices are related to the other choices. Second, we use bivariate statistical techniques to see whether there are associations in this sample between pimps’ ages and each of those decisions, and between each of those decisions and reported earnings. We find that younger pimps work with clients and sex workers in their social networks because they are easier to hold accountable, which leads younger pimps to bypass the self-reported risks involved with more violent work, but also tends be associated with lower self-reported earnings. Older pimps gravitate toward stranger clients, which involves more risk but higher earnings. Most pimps do not describe regularly using violence either against sex workers or to protect sex workers, but the use of violence is more common among older pimps. The accounts of regularly using violence with workers are not associated with higher earnings. The idea that pimps control most aspects of how sex workers labor and other aspects of their lives such as where they live are not substantiated by the accounts of the pimps themselves, but we do find older pimps describe exerting more control over sex workers than younger pimps. We discuss the implications of our findings, which demonstrate that pimps are a diverse group who see their own violence and control decisions as related to age, location, clientele, and perceived risks and rewards. 相似文献

The ability to perceive approximate numerosity is present in many animal species, and emerges early in human infants. Later in life, it is moderately heritable and associated with mathematical abilities, but the etiology of the Approximate Number System (ANS) and its degree of independence from other cognitive abilities in infancy is unknown. Here, we assessed the phenotypic specificity as well as the influence of genetic and environmental factors on the ANS in a sample of 5-month-old twins (N = 514). We found a small-to-moderate but statistically significant effect of genetic factors on ANS acuity (heritability = 0.18, 95% CI: 0.02, 0.33), but only when differences in numerosity were relatively large (1:4 ratio). Non-verbal ability assessed with the Mullen Scales of Early Learning (MSEL) was found to be heritable (0.47; 95% CI: 0.34, 0.57) and the phenotypic association between ANS acuity and non-verbal ability performance was close to zero. Similarly, we found no association between ANS acuity and general attention during the task. An unexpected weak but statistically significant negative association between ANS acuity and scores on the receptive language scale of the MSEL was found. These results suggest that early ANS function may be largely independent from other aspects of non-verbal development. Further, variability in ANS in infancy seems to, to some extent, reflect genotypic differences in the population.
Highlights
- Assessing 514 infant twins with eye tracking, we found that infants' sense of approximate numerosity is heritable and not positively associated with concurrent attentional, cognitive or motor abilities.
- These results have implications for our understanding of development of mathematical ability and the link between cognitive abilities early in postnatal life.

ABSTRACTWe argue that honesty in assertion requires non-empirical knowledge that what one asserts is what one believes. Our argument proceeds from the thought that to assert honestly, one must follow and not merely conform to the norm ‘Assert that p only if you believe that p’. Furthermore, careful consideration of cases shows that the sort of doxastic self-knowledge required for following this norm cannot be acquired on the basis of observation, inference, or any other form of detection of one’s own doxastic states. It is, as we put it, transparent rather than empirical self-knowledge. 相似文献
