In 1999, the Ontario provincial government introduced into its high school curriculum a requirement that students complete 40 h of volunteer community service before graduation. At the same time, the high school curriculum was shortened from five years to four. Consequently, the 2003 graduating class of Ontario high school students contained two cohorts, the first of the 4-year cohorts that was compelled to complete a mandated community service requirement, and the last of the 5-year cohorts that was not. Using a quasi-experimental design, we surveyed 1768 first-year university students in terms of their perceptions and attitudes about the nature and amount of previous volunteering, attitudes towards community service, current service involvement and other measures of civic and political engagement. Comparisons of the two cohorts indicate that, while there were discernible differences between the two cohorts in terms of their past record of community service, there were no differences in current attitudes and civic engagement that might plausibly be attributed to participation in the mandatory service program. Results are discussed with relation to the current debate concerning the impact of mandatory volunteering policies on intrinsic motivation to volunteer.

Abstract:  Effective removal of fingerprint deposits is crucial for experimentation related to the corrosion of metals by fingerprint deposits. Such removal is also necessary prior to deposition of test fingerprints. The effectiveness of four regimes in removing fingerprint deposits from brass is considered. Sustained wiping of the deposit with a tissue at applied pressures of up to c . 1430 Pa or rubbing while the brass was immersed in acetone both failed to remove completely all traces of fingerprint deposits. Heating the brass to 600°C was an effective remover; however, this also oxidized the surface of the metal except where inhibited by fingerprint deposits. The most effective regime, and the only one of the four that removed all traces of deposit without affecting the properties of the metal surface, was immersion in warm soapy water while rubbing with a tissue. We propose this as the preferred method for fingerprint removal.  相似文献

Educational attainment is a fundamental cornerstone to success throughout the life-course. As a result, ensuring that young people remain in school and are not truant is critical. Although the importance of truancy as a risk factor for many adverse outcomes, including crime, has been well-documented, much less methodologically rigorous work has been undertaken to evaluate potentially promising prevention and intervention strategies. This paper uses a randomized field trial method to test how a partnership between police and schools targeting truancy impacts offending in a sample of high-risk truanting young people. We find that the truancy intervention reduces offending and we discuss the implications for practice and directions for future research.  相似文献

ABSTRACT

Children under 10 are increasingly being referred to services for concerning problematic or harmful sexual behaviour, but information about interventions to support these children and their families is limited. A 3-year pilot of a group cognitive–behavioural intervention for children and their parents/carers is described. Forty-nine children were referred to the programme with 27 completing the programme in this period. This is the first intervention of its kind to be delivered with a UK population and demographic information is provided about the children who have been assessed, including information about age, gender, family composition and abuse history. Outcome data from the Trauma Symptom Checklist for Children, Child Sexual Behaviour Inventory, Strengths and Difficulties Questionnaire and the Parental Stress and Social Support Scale is reported. The available outcome data indicates the group has been largely beneficial in reducing problematic sexual behaviour. Key learning and implications for practice are discussed.  相似文献

Through analyzing the various factors in R2P's genesis and expansion as an international norm, this article contends that the office of the UN Secretary-General has provided steady backing of R2P, allowing for its ongoing consideration within the UN bureaucracy and among member states. In this respect, R2P has been able to assert itself in a meaningful way, with member states compelled to revisit the central tenets of the norm within the General Assembly and special dialogues. The office of the Secretary-General has clearly interpreted R2P as a strong and effective reinforcement of Article 1 of the UN Charter and the overall UN mandate, using the norm to more strongly anchor existing UN principles and values.  相似文献

Abstract

Understanding land accumulation dynamics is relevant for policy-makers interested in the economic effects of land inequality in developing country agriculture. We thus explore and simultaneously test the leading theories of micro-level land accumulation dynamics using unique panel data from Paraguay. The results suggest that farm growth varies systematically with farm size – a formal rejection of stochastic growth theories (that is, Gibrat’s Law) – and that titled land area may have considerable influence on land accumulation. Furthermore, our estimates indicate that a dualistic agrarian structure is the likely product of the unfettered operation of land markets.  相似文献

This article considers the motivations behind the introduction of the statutory requirement for local authority landlords, in making a decision to allocate housing, to give certain groups of people a ‘reasonable preference’. The discussion is set in the context of an examination of theories of local government covering the late nineteenth and early twentieth centuries. In particular, it examines whether central government's decision to restrict local authorities' previous freedom in this sphere was based on any principle or theory of local government or, rather, whether it was a pragmatic decision. An analysis of the Parliamentary debates leading to the relevant Housing Acts suggests that the central–local government relationship of this period was based on pragmatism. The over-arching question of the appropriate distribution of power and functions between the centre and the localities was relatively unimportant, compared with the very real question of how sufficient houses could be built, at rents that working class people could afford.  相似文献
