Suicide ideation among a stratified sample of rural and urban adolescents   总被引:1,自引:1,他引:0  
This study examined factors associated with sucidal ideation among a stratified sample of rural and urban adolescents. Data was collected on 1,728 eighth and tenth grade southern Nevada students from 23 schools. No overall differences were found between rural and urban adolescents, although results did indicate that grade, gender, and school achievement variations exist between rural and urban student populations. Implications for social workers and other youth service providers are discussed.  相似文献

This article outlines the development of evaluative methods within the field of mental handicap services. It suggests that evaluators have too often taken for granted the tacit assumptions underlying service models, using these to determine the criteria for evaluating success. It argues that evaluators should be more explicit about the values they adopt, and what patterns of life services should be enabling people to achieve. By more closely linking evaluation criteria to what people with a mental handicap should achieve, evaluation can become more effective in promoting positive change in service models. The article describes an approach developed by the authors for the evaluation of the 'All-Wales Strategy for the Development of Services for Mentally Handicapped People'.  相似文献

The present study examines suicide ideation and attempts as well as reported levels of physical and sexual abuse among gang and nongang-involved incarcerated youth. The self-report survey data were collected from 334 males and 61 females who were incarcerated in Nevada youth correctional facilities in the summer of 1994. Over half (58.3 percent) of the males and nearly half (45.2 percent) of the females reported being gang members. Surprisingly high rates of abuse (more than 70 percent for both physical and sexual abuse) were found among the incarcerated females of this study. Females reported significantly more suicide attempts and were more likely to have been physically and sexually abused than males. Nongang males reported significantly more suicide attempts and were more likely to report sexual abuse than gang-involved males. Among the gang-involved delinquents, females reported significantly more suicide attempts than males. In addition, gang members who reported sexual abuse were more likely to have higher levels of suicide ideationand to have attempted suicide. Implications for youth correction specialists and social workers are discussed.The data for this study were collected under Grant #000616 from the Nevada Agricultural Experiment Station.  相似文献

1. Specifying a model to guide research projects helps clarify the study, permits several investigators to work in a coordinated fashion on large projects, and facilitates comparisons across studies. 2. This model is composed of seven domains and indicates some of the hypothesized relationships between domains. Adapting the model to individual studies may result in a different number of domains and in the specification of other hypothesized relationships. 3. When possible, researchers should make use of minimum data sets to enhance the comprehensiveness and generalizability of their research.  相似文献

Average human life expectancies for the U.S. resident population are calculated using tabulated population and survival rate data. These life expectancies are recalculated assuming elimination of various types of motor vehicle fatalities using Fatal Accident Reporting System (FARS) data. The differences between the original and recalculated values provide estimates of life expectancy reductions due to the motor vehicle fatalities. These estimates are combined with prior work relating the likelihood of an occupant fatality to car mass, so that reductions in life expectancy are determined as a function of car mass. The estimates of life expectancy reductions are also used to determine the effect of seat belt use on life expectancy. The estimates, which are based on data for 1978, assume that survival rates remain unchanged. Estimates of the changes in life expectancy associated with switching from a large (1800 kg) car to a small (900 kg) car, and switching from not using to using a seat belt are presented as functions of the age at which an individual makes the switch.  相似文献

Although much has been learned about the global determinants of physical activity in adults, there has been a lack of specific focus on gender, age, and urban/rural differences. In this church-based community sample of Appalachian adults (N = 1,239), the primary correlates of physical activity included age, gender, obesity, and self-efficacy. Overall, 42% of all participants and 31% of adults age 65 years or older met recommended guidelines for physical activity, which suggests that most participants do not engage in adequate levels of physical activity. Of participants who met physical activity guidelines, the most common modes of moderate and vigorous activity were walking briskly or uphill, heavy housework or gardening, light strength training, and biking. These particular activities that focus on building self-efficacy might be viable targets for intervention among older adults in rural communities.  相似文献

Lipsky's Street-level Bureaucracy (Russell Sage Foundation, New York, 1980 Lipsky, M. 1980. Street-level Bureaucracy: The Dilemmas of Individuals in Public Service, New York: Russell Sage Foundation.  [Google Scholar]) has exerted a strong influence on the study of public service organisations. There has been a growing interest in using this perspective to understand the organisational context of social work and Musil et al.'s article in the EJSW (2004, ‘Do social workers avoid the dilemmas of work with clients?’, European Journal of Social Work, vol. 7, no. 3, pp. 305–319) reflects this interest. Musil et al. argue that it is possible to identify two forms of practitioner response to the constraints of street-level bureaucracies: adapting working practices in ways that disadvantage service users or challenging working conditions in order to achieve more professionally acceptable practice. Their contribution to the debate is helpful, particularly with regard to their identification of responses by practitioners that seek to advance the interests of service users. However, we view their approach as constrained by lack of consideration of the construction of social work roles within particular street-level bureaucracies. We suggest that Lipsky's work should be approached as a tentative analytic framework, rather than as a fixed model and we argue that a productive approach to research on social workers as street-level bureaucrats is conjunctural analysis. Such analysis examines the contexts, circumstances and statuses of practitioners and how these factors shape the specific forms of street-level practice that operate in particular organisational settings. We illustrate this in our discussion of the factors that are likely to have had a bearing on the two practice settings used as case studies by Musil et al.  相似文献
