In this chapter we offer a conceptual framework for the understanding of public service that allows for the incorporation of sociological themes of organizational structure and institutional power. We build on sociological conceptualizations of the self found in role identity theory, using examples from research on health care workers to show how role identities and organizational structures can both limit and enhance the likelihood of principled dissent. Finally, we extend our theoretical framework to better understand how community service is employed to address the structural sources of social problems.  相似文献

ABSTRACT

The purpose of the present study was to culturally adapt and validate the Children’s Knowledge of Abuse Questionnaire-RIII (CKAQ-RIII), a tool that examines children’s understanding of sexual abuse concepts, for use in Greek elementary schools. A sample of 467 Greek school children between the ages of 6–9 was recruited from a private school. The CKAQ-RIII was administrated three times, before and immediately after a Child Sexual Abuse (CSA) prevention intervention program, as well as during a one-year follow-up evaluation. A subsample of the original population (= 113) completed the one year follow up administration of CKAQ-RIII, along with the Body Awareness (BA) and the Emotional Differentiation (ED) subscales of the Emotion Awareness Questionnaire (EAQ). Internal consistency was high for the inappropriate touch scale (ITS) of the CKAQ-RIII and moderate for the appropriate touch subscale (ATS). Inter-item analysis showed that the majority of items were in an acceptable range. Pearson correlation coefficients analyses revealed strong associations between the two subscales of ITS and ATS, and the overall scores of the questionnaire. A mixed-subjects analysis of variance on the ITS showed an increase in knowledge post intervention, with third graders (8–9 year olds) generally scoring higher at baseline and demonstrating greater knowledge gains post intervention. A mixed-subjects analysis of variance was also conducted for the ATS where no significant increase in knowledge was found. Furthermore, analysis revealed a good concurrent criterion validity with good levels of agreement between CKAQ-RIII and ED, whereas no relationship was established between CKAQ-RIII and BA.  相似文献

Detailed data describing all homicides in Canada known to the police are collected by Statistics Canada. In this study, three independent teams of analysts search for seasonality and other temporal patterns in homicide rates and frequencies between 1961 and 1980.  相似文献

This paper examines the sleep disruption experienced by 36 families of technology‐dependent children living at home in the United Kingdom. The paper begins with an overview of the qualitative study in which parents' experiences of sleep disruption emerged as a major theme. We then describe the nature of and reasons for the sleep disruption, the help families received with care overnight, and the effects of sleep disruption on parents in particular. This is followed by discussion of the implications of the findings for policy and practice as well as future research.  相似文献

There have been three major analytical reviews that have examined the voluntary–statutory relationship during the 1990s, one undertaken by government in 1990 and the other two independently in 1993 and 1996. This article suggests that an historical understanding of this relationship (especially in terms of its sociopolitical dimensions) is crucial, but was missing from the 1990 review and misrepresented by the 1993 review. The 1996 document has been subjected to harsh criticism, but it was arguably sounder in its understanding of this fundamental issue. The national compact between representatives of the voluntary sector and the state, launched at the end of 1998, has built upon the arguments put forward in 1996. However, the paper suggests that given the vexed history of partnership between the sectors and the extent to which the statutory sector has become the dominant partner at the end of the 20th century, it would be premature to be overly optimistic. The paper examines three major shifts in the voluntary–statutory relationship during the 20th century, before reviewing the 1990s' documents in more detail.  相似文献

Why do some organizational changes persist, while others decay? The sustainability of change can be defined broadly as the process through which new working methods, performance goals and improvement trajectories are maintained for a period appropriate to a given context. However, sustainability has received limited attention, although the concept reflects Lewin's concern with ‘refreezing’ ( Lewin. K. 1951 . Field Theory in Social Science: Selected Theoretical Papers by Kurt Lewin, UK edition published 1952, ed. D. Cartwright, London: Tavistock). In an uncertain environment, working practices that fail to adapt are targets for change, and stability has been regarded not as a condition to be achieved, but as a symptom of inertia, a problem to be solved. This paper reviews the emerging literature, seeking to develop a provisional model of the processes influencing change sustainability and decay, as a platform for further research. This review suggests that sustainability is dependent on multiple factors, at different levels of analysis: substantial, individual, managerial, financial, leadership, organizational, cultural, political, processual, contextual and temporal. The relative significance of those factors cannot be determined a priori, raising questions concerning the properties of the sustainability process with regard to different types of change in different contexts.  相似文献

Acute Exposure Guideline Level (AEGL) recommendations are developed for 10-minute, 30-minute, 1-hour, 4-hours, and 8-hours exposure durations and are designated for three levels of severity: AEGL-1 represents concentrations above which acute exposures may cause noticeable discomfort including irritation; AEGL-2 represents concentrations above which acute exposure may cause irreversible health effects or impaired ability to escape; and AEGL-3 represents concentrations above which exposure may cause life-threatening health effects or death. The default procedure for setting AEGL values across durations when applicable data are unavailable involves estimation based on Haber's rule, which has an underlying assumption that cumulative exposure is the determinant of toxicity. For acute exposure to trichloroethylene (TCE), however, experimental data indicate that momentary tissue concentration, and not the cumulative amount of exposure, is important. We employed an alternative approach to duration adjustments in which a physiologically-based pharmacokinetic (PBPK) model was used to predict the arterial blood concentrations [TCE(a)] associated with adverse outcomes appropriate for AEGL-1, -2, or -3-level effects. The PBPK model was then used to estimate the atmospheric concentration that produces equivalent [TCE(a)] at each of the AEGL-specific exposure durations. This approach yielded [TCE(a)] values of 4.89 mg/l for AEGL-1, 18.7 mg/l for AEGL-2, and 310 mg/l for AEGL-3. Duration adjustments based on equivalent target tissue doses should provide similar degrees of toxicity protection at different exposure durations.  相似文献
