Lifestyle Education for Activity Program (LEAP) was a comprehensive, school-based intervention designed to promote physical activity in high school girls. The intervention focused on changes in instructional practices and the school environment to affect personal, social, and environmental factors related to physical activity. Multiple process evaluation tools and an organizational assessment tool were developed to monitor program implementation from a framework called the LEAP essential elements, which characterized complete and acceptable intervention delivery; secular trends were also monitored. Using process data, LEAP intervention schools were categorized into low- and high-implementing groups and compared with control schools on nine essential elements assessed at the organizational level. The Wilcoxon scores test revealed that low- and high-implementing intervention, and control schools differed significantly on two of nine administrator-reported organizational-level components: having a physical activity team and having a faculty-staff health promotion program. A mixed-model analysis of covariance indicated that, compared to control schools, a greater percentage of girls in high-implementing schools reported engaging in vigorous physical activity. Process evaluation can be used to understand the relationship between level of implementation and successful program outcome.  相似文献

This paper reports on the last of three National Hospice and Palliative Care Organization initiatives to move hospice and palliative care social workers into the patient/family outcomes arena: the development of the Social Work Assessment Tool. The experience of a team of practitioners and researchers is described, including results of two pilot studies and subsequent SWAT revisions. The major focus is on the current model performance improvement project, in which 19 social workers from 14 hospice and palliative care programs used the SWAT with 101 patients and 81 primary caregivers for a median of 44 days. Quantitative analysis indicated significant improvement in SWAT scores for patients from the first to the second social work visit (t = -2.60, df = 47, p .01). Qualitative interviewing of the social workers indicated some lack of readiness in the field to conduct quantitative outcomes measurement. Additional measures are needed in addition to the SWAT, including qualitative measures, and measures of mezzo and macro practice. Participants indicated that the SWAT was appropriate for use with economically and culturally diverse clients.  相似文献

Multiple comparison procedures are extended to designs consisting of several groups, where the treatment means are to be compared within each group. This may arise in two-factor experiments, with a significant interaction term, when one is interested in comparing the levels of one factor at each level of the other factor. A general approach is presented for deriving the distributions and calculating critical points, following three papers which dealt with two specific procedures. These points are used for constructing simultaneous confidence intervals over some restricted set of contrasts among treatment means in each of the groups. Tables of critical values are provided for two procedures and an application is demonstrated. Some extensions are presented for the case of possible different sets of contrasts and also for unequal variances in the various groups.  相似文献

The essay analyses the photographs produced and circulated during the March 2011 tsunami and earthquake disaster in Japan, which show destroyed buildings, flooded landscapes, desperate people. Disaster destroys existing order. On first sight, the photographs of disaster depict this dissolution of order. The empirical analysis shows that the disastrousness of disaster is (also) created through the pictures of the disasters. The paper discusses why and in what way certain pictures reveal themselves to be iconographic of disaster and how they enter the visual memory as its representative. To achieve this, the study will invoke ethnomethodology. At the centre of the analysis is the question of the particular means with which these images illustrate the destructive force of the disasters and how pictures showing destruction and pain (‘pictures of pain’) turn into pictures effecting pain in the viewer (‘painful pictures’). The empirical study demonstrates: the photographs show the destruction of order; however, they do this in an orderly manner.

This paper discusses the results from a survey on the gendered impact of organizational change and the implications for workloads and working hours. These results suggest that restructuring leads to increased workloads and that the pressure of long working hours is associated with male-dominated organizations. Restructuring is also associated with 'presenteeism' (the tendency to stay at work beyond the time needed for effective performance of the job) as fear of redundancy and uncertainty over promotion opportunities lead to a need to demonstrate visible commitment. Such presenteeism was found to be gendered: it is associated with a competitive masculine culture, it is seen by women as a form of 'male resistance' to their presence as managers and it imposes heavy costs on women as they attempt to meet the conflicting demands of work and home. This paper suggests that organizational restructuring can produce dysfunctional outcomes such as 'competitive presenteeism' (whereby managers compete over who stays longest in the office) and that such outcomes have important gender implications. It concludes that gender mix is a defining feature in how well women fit into the organization and how easily they accommodate to changes in organizational structures and managerial work.  相似文献

Discriminatory housing market practices have created and reinforced patterns of racial residential segregation throughout the United States. Such segregation has racist consequences too. Residential segregation increases the concentration of disadvantage for blacks but not whites, creating African-American residential environments that heighten social problems including violence within the black population. At the same time, segregation protects white residential environments from these dire consequences. This hypothesized racially inequitable process is tested for one important type of violence—homicide. We examine race-specific models of lethal violence that distinguish residential segregation from the concentration of disadvantage within racial groups. Data are from the Censuses of Population and Federal Bureau of Investigation's homicide incidence files for U.S. large central cities for 1980 and 1990. Our perspective finds support in the empirical analyses. Segregation has an important effect on black but not white killings, with the impact of segregation on African-American homicides explained by concentrated disadvantage.  相似文献

Little is known about factors associated with child welfare case duration. Understanding factors associated with case duration may help stakeholders make more informed decisions about funding and service allocation and improve compliance with federal law. This study had two research questions: (1) What factors are associated with child welfare case duration? And (2) Do factors differ depending on whether children were placed exclusively with parents or with others (e.g. relatives and foster care) during the case? The study sample consisted of families (N = 874) with co-occurring child maltreatment and substance use in one midwestern state in the United States between 2007 and 2016. Linear regression models were used to identify correlates of case duration while controlling for child placement status. Overall, having a child under 1 year of age, benzodiazepine use, methamphetamine use and injection drug use were all associated with longer case duration, whereas marijuana use with no other substance use was associated with shorter case duration. Additionally, factors associated with case duration differed based on child placement status during the case. These findings suggest important heterogeneity in families involved with child welfare services and may allow for proactive mitigation of cases at greater risk.  相似文献

If today there exists a single transcendent idea about the family‐school connection, it is that a positive parent‐child relationship improves children's chances of succeeding in school. However, using data from the Texas Higher Education Opportunity Project (N = 5,836), we demonstrate that, although positive parent‐child relations are associated with better academic achievement in high school, they also are associated with an increased desire to live at home during college, which in turn decreases students' chances of enrolling in a 4‐year college. Furthermore, we replicated some of these associations using the National Longitudinal Study of Adolescent Health (N = 10,120), demonstrating that positive family dynamics can influence educational outcomes in potentially divergent and unanticipated directions.  相似文献
