The author surveyed field instructors of second-year graduate students to ascertain the instructors’ assessments of their students’ preparedness for and skill in social work practice. The variable of interest was traditional second-year or advanced placement status. Results indicate that, with few exceptions, there were no differences in field instructors’ evaluations based on status; those that existed favored advanced placement students. The implications of the findings for the continuing debates over advanced placement and an articulated continuum regarding the bachelor’s versus master’s social work degree are discussed.  相似文献

Previous research has suggested a link between household dynamics (i.e., average household size and number of households) and environmental impacts at the national level. Building on this work, we empirically test the relationship between household dynamics and fuelwood consumption, which has been implicated in anthropogenic threats to biodiversity. We focus our analysis on developing countries (where fuelwood is an important energy source). Our results show that nations with smaller average households consume more fuelwood per capita. This finding indicates that the household economies of scale are, indeed, associated with the consumption of fuelwood. In addition, we found that number of households is a better predictor of total fuelwood consumption than average household size suggesting a greater relative contribution to consumption levels. Thus, insofar as declining average household sizes result in increased number of households and higher per capita consumption, this trend may be a signal of serious threats to biodiversity and resource conservation. We also found further support for the ??energy ladder?? hypothesis that economic development reduces demand for traditional fuels.  相似文献

Recent studies suggest that even infants attend to others’ beliefs in order to make sense of their behavior. To warrant the assumption of early belief understanding, corresponding competences need to be demonstrated in a variety of different belief‐inducing situations. The present study provides corresponding evidence, using a completely nonverbal object‐transfer task based on the general violation‐of‐expectation paradigm. A total of n = 36 infants (15‐month‐olds) participated in one of three conditions. Infants saw an actor who either observed an object’s location change, did not observe it, or performed the location change manually without seeing it (i.e., variations in the actor’s information access). Results are in accordance with the assumption that 15‐month‐old infants master different belief‐inducing situations in a highly flexible way, accepting visual as well as manual information access as a proper basis for belief induction.  相似文献

Mediterranean landscapes resulted from complex land uses that produced a mosaic of extensive crops, grasslands, scrublands and scattered woodlands. During the twentieth century the decrease in traditional agriculture triggered a decrease in open habitats and an increase in forests. In the meantime urban centres grew dramatically. Both spread of forest and urban areas have been suspected to participate in the decline of typical Mediterranean bird species and, in general, to cause faunal loss. However, modern cities offer a variety of landscape types and, in the Mediterranean, their value for native bird species has been little assessed. We compared the bird communities from an urban landscape, including built up and natural or semi natural units within the limits of the city of Montpellier, to the bird communities from non-urban habitats (cropland, grassland and woodland) located nearby but away from direct urban influence. Fifty four percent of the bird species recorded in the non-urban habitats also occurred in the urban landscape. On average, estimated species richness in the urban landscape was similar to values obtained for non-urban habitats. Within the urban landscape species richness was lowest in the dense historical centre and highest in the residential areas. The residential areas and urban woods were suitable habitats for most generalist species but also for several more specialized species recorded in the non-urban habitats. Some species actually reached their highest observation frequency in the urban landscape. Urban landscape was least favourable to the same farmland and open-habitat specialists that have been negatively affected by agricultural abandonment in the region. Finally, five of the species common in the urban landscape had an unfavorable conservation status in 2004 in the EU. This study emphasizes that Mediterranean urban areas have the potential to host a diverse native bird community. Finding ways to improve their carrying capacity for the local avifauna might be a worthwhile objective for animal conservation.  相似文献

In the study reported here, BSW and MSW students in field placements and a group of recent MSW graduates were surveyed to assess the impact of personal attributes, supervisory characteristics, and 11 instructional skills on their evaluation of their field instructors. Results indicated that the most influential variables were those representing task-oriented, educational aspects of field instruction. In addition, field instructors' availability, their use of process recordings, and the amount of supervision they gave students also influenced respondents' evaluations.  相似文献

After friends and relatives, childminders are the most common form of child care. This paper reports the results from a postal survey of a nationally representative sample of over 1,000 childminders. Results are reported concerning childminders' training and employment histories, working conditions, motivation, commitment and satisfaction with their work. Two groups of childminders emerge; a group where childminding may be a passing phase in their employment career and a group who consider it as a long‐term career. The findings are discussed with reference to the aims of the National Childcare Strategy and the role of Early Years Development and Childcare Partnerships.

There is growing recognition of the need to examine distinct forms of prosocial behaviors and to conduct research on prosocial behaviors among ethnic minorities. Middle school students (mean age=12.67 years; 54% girls; European American, n=290; Mexican American, n=152) completed a multidimensional measure of prosocial behavior and measures of parental monitoring, externalizing behaviors, and religiosity. Results yield supportive evidence that anonymous, dire, emotional, compliant, public, and altruism are different forms of prosocial behaviors. Moreover, the measure of prosocial behaviors shows measurement equivalence properties across ethnicity and gender. The discussion focuses on the multidimensional nature of prosocial behaviors and implications for future research on prosocial behaviors.  相似文献

Mexican American adolescents face disparities in mental health and academic achievement, perhaps in part because of discrimination experiences. However, culturally related values, fostered by ethnic pride and socialization, may serve to mitigate the negative impact of discrimination. Guided by the Stress Process Model, the current study examined risk and protective processes using a 2‐wave multi‐informant study with 750 Mexican American families. Specifically, we examined 2 possible mechanisms by which Mexican American values may support positive outcomes in the context of discrimination: as a protective factor (moderator) or risk reducer (mediator). Analyses supported the role of Mexican American values as a risk reducer. This study underscores the importance of examining multiple mechanisms of protective processes in understanding Mexican American adolescent resilience.  相似文献

This study examines the influence of family, peer, and biological contributors to dating involvement among early adolescents (11–14 years of age; = 244). Further, we assess how parental monitoring may be modified by pubertal maturation and older sibling risky behavior. Data on delinquent peer affiliation, pubertal maturation, parental monitoring, older sibling risky behavior, and dating involvement were gathered through observations and surveys from adolescents, mothers, older siblings, and teachers. Results indicate that lower levels of parental monitoring and higher levels of older sibling risky behavior were related to adolescents' dating involvement through delinquent peer affiliation. Pubertal maturation was directly related to dating involvement for early daters. Findings emphasize the value of examining social and biological factors, in concert, over time.  相似文献
