According to recent studies, large numbers of children and adolescents with serious emotional or behavioral disorders receive either no mental health treatment or treatment inappropriate to their needs. In this article the authors examine the problem of unnecessary hospitalization and the inadequacy of community-based systems. They discuss the barriers that impede improved mental health service systems for children and their families and present the Child and Adolescent Service System Program (CASSP) “system of care” model as an alternative. Last, counseling and development's role in promoting and fostering positive changes in the mental health system serving children and adolescents is discussed.  相似文献

In the psychophysical literature describing the relationships between physical and psychological magnitudes, as physical intensity increases, perceived intensity often grows much faster near threshold than at higher levels. In this laboratory, however, the loudness curve for sinusoidal vibrotactile stimuli was best fit by a single-limbed function rather than by the expected two-limbed function. In the present study, we measured the growth of vibrotactile loudness of 250-Hz sinusoidal stimuli by the method of absolute magnitude estimation to explore the source of the one- versus two-limbed discrepancy. The number of times that the stimulus was presented was varied, as well as whether the stimulator contacted the skin with constant force or constant penetration. Neither of these manipulations affected the shape of the loudness function consistently. Number of repetitions influenced the shapes of the magnitude estimation functions, but only for a few individuals. Skin-contactor coupling did not affect the shapes of the functions, although the absolute level (vibrotactile loudness) was consistently greater for constant indentation.  相似文献

Research on social comparison processes has assumed that a comparison in a given direction (upward or downward) will lead to a particular affective reaction. In contrast, the present two studies proposed and found that a comparison can produce either positive or negative feelings about oneself, independent of its direction. Several factors moderated the tendency to derive positive or negative affect from upward and downward comparisons. In Study 1, cancer patients low in self-esteem and with low perceived control over their symptoms and illness were more likely to see downward comparisons as having negative implications for themselves. Those low in self-esteem were also more likely to perceive upward comparisons as negative. In Study 2, individuals with high marital dissatisfaction and those who felt uncertain about their marital relationship were more likely to experience negative affect from upward and downward comparisons. The implications of these findings for social comparison theory and for the coping and adaptation literature are discussed.  相似文献

The effects of an alcohol education presentation with a media component of public service announcements were evaluated. The presentation was conducted over three (consecutive) days with 10th and 11th grade students in a rural area of South Carolina. The professionally produced announcements focused on drinking and driving. 52 subjects were assigned by classroom to either of two treatment groups or a control condition. Both treatment groups received the educational presentation but differed in that Group 2 was also exposed to the videotaped announcements. Effects of exposure were evaluated in separate measures of knowledge, attitudes, and alcohol involvement, using a pre-posttest design, with a 1-mo. follow-up. Analysis showed an effect of over-all program on knowledge at follow-up, but none on attitudes or alcohol involvement. These findings and their implications are discussed in the context of previous evaluations of alcohol education programs and media efforts.  相似文献

To test theoretical ideas derived from classic and recent social comparison theory, two studies examined affiliative tendencies as a response to marital problems among individuals varying in marital dissatisfaction. Study 1 (n. = 632) showed that the higher the degree of marital dissatisfaction and the higher the uncertainty about how things are going in one's marriage, the stronger was the desire for affiliation (operationalized as the desire to talk with others about one's marriage). Moreover, among individuals high in marital dissatisfaction, a preference for upward affiliation was found, i.e. for contact with others having better marriages. Individuals with lower levels of dissatisfaction preferred affiliation with similar others. Women experienced more uncertainty and a stronger affiliative tendency than men. In Study 2 (n = 233), these findings were largely replicated. Moreover, it was shown that the desire to affiliate when facing marital stress was particularly strong among individuals high in interpersonal orientation.  相似文献

Although sexual harassment naming – the process by which individuals identify and label experiences as sexual harassment – is key to tackling the problem of workplace sexual harassment, extant research focused on individual differences has explained a limited amount of variance in individuals’ propensity to name. We push this research in a new direction, drawing on institutional theory and strategic human resource management to identify workplace contextual factors that influence individuals’ propensity to name sexual harassment. Surveying 408 employed adults, we find that current employment in an industry with a high prevalence of sexual harassment reduces individuals’ likelihood of identifying scenarios as sexual harassment. Further, prior work experience in highly sexually harassing industries has a lasting negative effect on individuals’ propensity to name. In contrast, we show that individuals’ propensity to identify sexual harassment is greater when they perceive that their organization has implemented more HR practices supporting a climate for naming and that these HR practices can actually reduce the negative effect of current employment in a highly sexually harassing industry. Critically, by demonstrating that changing industry norms or adopting specific HR practices can shift individual naming of sexual harassment, we offer new avenues for sexual harassment prevention.  相似文献

Drawing on marketing and recruitment theory, we examined relationships among early recruitment practices, organizational factors, and organization-level recruitment outcomes, predicting that low-involvement recruitment practices, high-involvement recruitment practices, corporate advertising, and firm reputation would positively affect the quantity and quality of organizations' applicant pools. We also predicted that corporate advertising and firm reputation would moderate the effects of the 2 recruitment strategies. Data for 99 organizations collected from multiple sources provided some evidence that early recruitment practices, corporate advertising, and firm reputation each had direct effects on applicant pool quantity and quality. More importantly, we found that low-involvement recruitment practices were more effective for firms with relatively low levels of corporate advertising and firm reputation, whereas high-involvement recruitment practices were more effective for firms with relatively high levels of advertising and reputation.  相似文献

I respond to Selinger and Mix (Selinger, E. and Mix, J. 2004. On interactional expertise: Pragmatic and ontological considerations. Phenomenology and the Cognitive Sciences 3: 145–163), concentrating on their charges that Collins (Collins, H. M. 2004a. Interactional expertise as a third form of knowledge. Phenomenology and the Cognitive Sciences 3: 125–143) underrates the importance of interactional expertise as an expertise sui generis and that the paper fails to analyse the idea of embodiment sufficiently holistically, misleading treating the ‘body’ as no more than the linear sum of its parts. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

The standard view of truth-conditional semantics is that it is world-involving in the sense that a theory that specifies truth conditions eo ipso is a theory that specifies the way the world must be if the target sentences are to be true. It would appear to follow that the semantic properties of expressions, such as nominals, specify the very worldly objects that make true or false the sentences that host the nominals. Chomsky and others have raised a fundamental complaint against this thought: perfectly quotidian nominals, such as London or book, may occur copredicatively as a single argument of categorically mismatched predicates, which prima facie preclude a coherent uniform construal of the nominal argument. The argument has hitherto been presented via examples that challenge the standard view. My aim here is to present the argument explicitly, defend it against some likely counterclaims, and resolve what might appear to be a decisive consideration against the conclusion of the argument, viz., if nominals as copredicatively occurring do not contribute uniform worldly entities, then how can the copredicative constructions be counted as true?  相似文献
