Abstract

In 2006 Western Australia passed legislation that introduced a system to check criminal records and issue permits to those who wish to work with children. In 2007, the legislation was described by the minister responsible as a “powerful system that would prevent harm to children”. This paper explores that system and identifies limits to its effectiveness. The paper concluded that unless the system's limits are fully appreciated there is a possibility of a paradoxical outcome, whereby children's lives will be less safe. It also raises the question of whether in the area of record checking a national approach is not preferable to each state and territory developing its own system.  相似文献

Abstract

One month before the June 2007 Federal Government Emergency Intervention in the Northern Territory some 55 West Australian Aboriginal child protection workers attended a 3-day summit in Fremantle. Their purpose as front-line practitioners from across the State was to identify how more nurturing and healing communities could be developed and supported in a climate of despair. This paper reports on how the summit was designed and on some of the ideas and concerns that emerged within this dialogical space of cooperative inquiry. The project was a partnership between Aboriginal and non-Aboriginal representatives of university, government, and community-service bodies. Aboriginal practitioners identified the complexity of what was happening in their experience and where changes were needed. Integral to this participation and coproduction of knowledge by Aboriginal child protection workers was the provision of a safe space for the articulation of reflected experience. Implications for policy, practice, and curriculum of both process and outcome dimensions to considering Aboriginal views on this contentious issue are discussed.  相似文献

ABSTRACT

Objectives: Identification of health-related risk behaviors associated with well-being in college students is essential to guide the development of health promotion strategies for this population. The purposes were to evaluate well-being among undergraduate students and to identify health-related risk behaviors that predict well-being in this population. Methods: A cross-sectional Web-based survey of undergraduate students was conducted at a metropolitan university in the Southeast United States. A total of 568 students responded (response rate 14.2%). Data were collected on health-related risk behaviors using the National College Health Assessment II. Results: Controlling demographic characteristics, the best predictive model included physical activity, current tobacco user, depression, ever received mental health services, and sleep quality, which was the strongest predictor (β = .45, p < .001). This model explained 35% of the variance in well-being. Conclusions: Interventions that promote sleep quality among college students may be most beneficial in improving well-being.  相似文献

We consider online optimization problems in which certain goods have to be acquired in order to provide a service or infrastructure. Classically, decisions for such problems are considered as final: one buys the goods. However, in many real world applications, there is a shift away from the idea of buying goods. Instead, leasing is often a more flexible and lucrative business model. Research has realized this shift and recently initiated the theoretical study of leasing models (Anthony and Gupta in Proceedings of the integer programming and combinatorial optimization: 12th International IPCO Conference, Ithaca, NY, USA, June 25–27, 2007; Meyerson in Proceedings of the 46th Annual IEEE Symposium on Foundations of Computer Science (FOCS 2005), 23–25 Oct 2005, Pittsburgh, PA, USA, 2005; Nagarajan and Williamson in Discret Optim 10(4):361–370, 2013) We extend this line of work and suggest a more systematic study of leasing aspects for a class of online optimization problems. We provide two major technical results. We introduce the leasing variant of online set multicover and give an \(O\left( \log (mK)\log n\right) \)-competitive algorithm (with n, m, and K being the number of elements, sets, and leases, respectively). Our results also imply improvements for the non-leasing variant of online set cover. Moreover, we extend results for the leasing variant of online facility location. Nagarajan and Williamson (Discret Optim 10(4):361–370, 2013) gave an \(O\left( K\log n\right) \)-competitive algorithm for this problem (with n and K being the number of clients and leases, respectively). We remove the dependency on n (and, thereby, on time). In general, this leads to a bound of \(O\left( l_{\text {max}} \log l_{\text {max}} \right) \) (with the maximal lease length \(l_{\text {max}} \)). For many natural problem instances, the bound improves to \(O\left( K^2\right) \).  相似文献

Although there is a growing body of knowledge about health among African American women in general, there is a dearth of information on African American lesbians. The primary purpose of this study was to investigate the correlates of health-related quality of life among African American lesbians using a cross-sectional anonymous survey with topics and measures developed by members of the African American lesbian community. Surveys were completed by 123 English speaking adult women who identified as African American lesbians and were attending the Zuna Institute's National Black Lesbian Conference. Overall, we found a very high health-related quality of life, in spite of a high frequency of health impairments. The average body mass index (BMI) for this sample was 32.2 (SD?=?8.0); 13% were morbidly obese, having a BMI of 40 or more and only 15% of the women were in a healthy weight range; advancing age was associated with poorer physical functioning, decreased physical role functioning, and more pain. Health-related quality of life was associated with depression and spirituality, but not religion. This study highlights the need for subjective measures of health-related quality of life as well as checklists of diseases and disorders.  相似文献

This study discusses the qualitative lessons learned from a joint social work difficult dialogue education project undertaken by students from a historically Black college and university (HBCU) and those from a predominantly White institution (PWI). The assignment utilized critical pedagogy as a guiding theory to facilitate difficult dialogues about diversity, privilege, and difference through social media and technology. Qualitative data analyzed from the project points to the usefulness and challenges of using social media and technology in facilitating difficult dialogues as well as the need to train students more purposely in the effective use of social media and technology during their education in order to prepare them for practice.  相似文献

Athletic activities are associated with reduced levels of stress and negative mood states among heterosexuals; thus, examining this association among gay/bisexual men is warranted. The current study examined the relationship between sports motivation and mood states, self-esteem, body esteem, life satisfaction, perceptions of masculinity/femininity, and parental encouragement for athletic endeavors among 195 gay/bisexual men. The results were mixed, but suggest that sports participation among gay/bisexual men may relate to a desire to express their masculinity and maintain a positive body image. Gay/bisexual men may be more likely to participate in sports if they receive positive reinforcement from others.  相似文献

Understanding the role of drinking games in college student life is critical for program planners who wish to develop education and prevention programs to reduce abusive drinking. Drinking games are popular social activities that provide a focus for social interactions but place students at considerable risk for serious consequences. This article reports preliminary results of a study using participant observation and in-depth interviews to develop a typology of drinking games and describe patterns and practices associated with the games.  相似文献

This paper provides some simple methods of interpreting the coefficients in multinomial logit and ordered logit models. These methods are summarized in Propositions concerning the magnitudes, signs, and patterns of partial derivatives of the outcome probabilities with respect to the exogenousvariables. The paper also provides an empirical example illustrating the use of these Propositions.  相似文献
