Assessing Participation and Effectiveness of the Peer-Led Approach in Youth Sexual Health Education: Systematic Review and Meta-Analysis in More Developed Countries

Sexual health education for young people is crucial not only for development of norms but also for protection against vulnerabilities during this stage in life. Although several systematic reviews have examined the effectiveness of peer-led sex education, none have focused on the extent of peer participation. The purpose of this review was to evaluate peer-led sexual health education interventions in more developed countries (MDCs). Electronic and manual searches across five social science, education, and medical databases were conducted. Fifteen articles were selected in total. Most (10 of 15) studies gave low or no responsibility to peers. The majority of articles found improvements in sexual health knowledge (13 of 14) and attitudes (11 of 15) at postintervention stages. Two studies showed improved self-efficacy, and three showed behavioral changes. A preliminary synthesis of effectiveness and level of participation was done. Meta-analysis revealed a large effect on knowledge change (Hedges’ g = 0.84, 95% confidence interval [CI]: 0.43 to 1.25) and a medium effect on attitude change (Hedges’ g = 0.49, 95% CI: 0.19 to 0.80). Peer-led interventions could be a powerful tool. This review shows that this approach is effective in changing knowledge and attitudes but not behaviors. Further research and action are needed to understand optimal implementation.     

Emotional balance and probability weighting

We find suggestive evidence that emotional balance has an impact on probability weighting incremental to demographic controls. Specifically, low negative affectivity (implying high emotional balance) tends to be a characteristic of those whose probability weighting functions exhibit lower curvature and more neutral elevation. In other words, emotional balance seems to push people in the direction of normative expected utility theory.     

基于尾部指数回归方法的CVaR估计以及实证研究

 在险价值VaR是一种非常重要的金融风险度量方法,近期也有很多关于动态VaR以及条件VaR (CVaR) 等方面的研究。根据金融资产的收益率具有重尾特征这一事实,本文假定金融资产收益率服从重尾分布,并假定重尾分布的尾部指数随着收益率发生变化。本文基于尾部指数回归模型对重尾分布的尾部指数进行估计,进而得到收益率尾部数据所服从的条件分布,并首次运用该方法对条件VaR进行估计。本文对沪深300指数进行了实证研究,得到CVaR的估计,并对估计得到的CVaR的预测效果作出检验,并与传统VaR估计方法进行了对比,实证结果发现本文的方法的预测效果更好。     

专业、科学、本土化:中国社会工作十年的三个迷思

在中央政府大力倡导建立一支庞大社工队伍的形势下,中国社会工作已渐渐进入政府不同的职能部门,社会工作岗位的建设亦日见增多。在快速增长的过程中,中国社会工作的发展已突破了很多原来的限制,如教材不足、师资不够等。但是在关于社会工作作为一个专业在中国的发展的讨论中,至少有三个问题仍然不断缠扰着中国社会工作学界:社会工作的专业性、科学性、本土化。中国社会工作的发展一定要扎根于中国复杂的国情,有机地结合本土和非本土社会工作的技术和文化价值基因。     

Subethnic interpersonal dynamic in diasporic community: a study on Chinese immigrants in Vancouver

ABSTRACT

Ethnicity is a social construct that can be conceptualised as a social classification delineating certain boundaries between an ethnic group and the dominant group. Members of an ethnic group are assumed to share similar cultural characteristics and to be homogenous among themselves. Many studies in ethnic organisations have indicated that subethnicity also exists within an ethnic group, but research on subethnicity is scant. Based on the findings of an exploratory study conducted in Vancouver, Canada, we examined how, at an interpersonal level, place of origin, language, mutual bias and discrimination and transnational politics divide the Chinese diasporic community subethnically. Meanwhile, being Chinese in the Canadian context and willingness to break the subethnic boundaries are noted as counterforces to the subethnic divide. We contend that interpersonal interaction is an imperative dimension for the understanding of the shaping of boundary between different subethnic groups.     

交际视野下的规约性隐含逻辑初探——以兼为因果关系词句为例

在翻译实践过程中往往会遇到某些规约性隐含逻辑现象。在这一过程中,译者往往需要通过相关的信息解码来重新建构语言。交际视野下的规约性隐含逻辑现象主要表现为三个方面,即三种典型的逻辑交际模式。对于原语与目的语之间的兼为因果关系词句应采取必要而灵活的方法和策略。     

Imagining Social Work: A Qualitative Study of Students' Perspectives on Social Work in China

Social work education in China has expanded rapidly since it was reintroduced in 1988. This has led to a growing body of English language literature on the development of social work education in China. However, thus far, this literature lacks an empirical foundation and little research on students' perspectives has been done. To fill this gap, this paper reports on a qualitative study of a group of graduating social work students (n = 32) from four social work programmes in Jinan, the provincial capital of the Shandong Province. Three major findings are reported. Firstly, the students liken their social work learning experience to a roller coaster ride with many ups and downs. Secondly, the cultural compatibility of western social work in China has not yet been conclusively established, while an ‘indigenized’ social work needs to be compatible with Chinese family values, referred to as ‘familism’ in direct Chinese to English translation, and with the dominant socialist political ideology. Thirdly, the future of social work is bright given increasing government support for its development.     

Social work in the making: The state and social work development in China

The instrumental role of government in the development of social work in China has led to questions about its political function. So far, little has been reported on how the government has “made” social work in China. To fill this gap, we first provide a brief chronological review of major policies and activities of the Chinese government in its making of social work in China. The state's intervention has indeed been massive and crucial although, politically, it may limit the mandate of social work in China. Yet, we argue that the development of the social work profession in China is generating institutional space for the emerging civil society to take a more active role in welfare service delivery. Situated and mediating between the state and the emerging civil society, the social work profession in China will need to constantly negotiate its mandate to meet the needs of both sides.
