社会主义荣辱观教育对青年教育的诉求

荣辱观是中国道德体系的核心和基础.在社会转型期,随着青年社会作用和地位的凸显,他们既需要社会主义荣辱观的引导,又对荣辱观深入人心起着积极的示范效应;青年教育通过时积极价值观的选择,对消极价值观的遏制及其灵活多变的途径应成为有效进行荣辱观教育的必然诉求.

Suicide and mental health problems among Swedish youth in the wake of the 1990s recession

The purpose of this explorative study is to bring together a variety of Swedish data sources with indicators of youth mental health and living conditions in order to illuminate trends during the last decades, elucidate possible determinants of mental ill health and develop hypotheses to explain the observed trend patterns. The analyses in the study reveal some surprising inconsistencies with respect to the mental health trends among young people during the 1990s. Most striking is the pattern of increasing youth unemployment coinciding with almost inverse trends in the rates of suicide. The secular trends in fatal suicides during this period do not show any increase but some actual decrease in sub‐populations despite high sustained levels of unemployment. In contrast, survey data indicate that the general mental health of youth during this period appears to have deteriorated.     

Growing up on the sidelines: identity negotiations of Palestinian youth from ‘collaborating’ families relocated to Israel

By examining the experiences of the children of Palestinian collaborators whose families have relocated to Israel, this study explores how youth negotiate self within the context of marginalisation and cultural dislocation. Due to the actions of their parents, the research participants have become outsiders and outcasts in their Palestinian communities of origin, outsiders in Israel, and outsiders among Israeli-Arabs. Based on qualitative, in-depth interviews with 11 Palestinian male youths, we describe and analyse the experience of identity negotiation in the context of fear and their families’ past deceit. Our findings highlight that the youths’ identities are negotiated by engaging in a dialogue of self on belonging and not belonging that is based on visions of their past, present and future selves. This is accompanied by a forced dialogue with others, explaining who they are in order to fit in with the ‘audience’, a presentation that is then acted out.     

Expediting youth's entry into employment whilst overlooking precariousness: Flexi‐employability and disciplinary activation in Hong Kong

With an emphasis placed on supply‐side interventions such as skills training and incentives enhancement, active labor market polices (ALMPs) are strongly promoted by international organizations and widely adopted across different welfare regimes to boost employment rates. This article first presents the under‐examined relationship between ALMPs and employment precariousness, which has posed a challenge to the neoliberal notion of employability and activation. Youth‐focused employment policies tend to speed up employment entry whilst downplaying the risk of precariousness and the importance of job quality, and thus further reinforcing the belief that engaging in precarious employment is tolerable if not inevitable. The article then examines the case of Hong Kong, which illustrates that its relatively low rate of youth unemployment may conceal the unfavorable employment conditions confronted by youth. It is argued that the service‐led employment policies and short‐term vocational training define the employability of young workers in terms of labor flexibilities. The coined phase of “flexi‐employability” is characterized by promoting youth's readiness for, and adaptability to, the volatilities and changing demands of the labor market. Arguably, the disciplinary approach to youth activation would only strengthen the work‐first principle by enforcing young people to take up jobs available and leave welfare as soon as possible, but without thoroughly addressing the risks and insecurities generated by the labor market in undermining their well‐being.     

A port in a storm: Spontaneous volunteering and grassroots movements in Amsterdam. A resilient approach to the (European) refugee crisis

This article seeks to expand knowledge about spontaneous volunteering in Amsterdam during the European refugee crisis in the winter of 2015–16. As formal institutions, which relied on a top–down command and control approach, were unable to handle the relatively large number of refugees who arrived in a short period of time, grassroots social movements based on bottom–up participation emerged. Grassroots volunteers were not only politically engaged, protesting against the strict refugee reception policy, but they also became involved in the crisis response, showing a great deal of flexibility. Although the social movements struggled with their organizational structures, they were able to adapt their missions and structures to changing circumstances. To achieve a resilience‐based response to future refugee influxes, this article advocates for formal response organizations to dismantle their static, top–down approach, and for social movements to find a balance between participation and professionalism. If institutionalized refugee response organizations adapt to the dynamics of local conditions, they could create the conditions for resilient solutions in the crisis context.     

Sexual Health Services for Homeless Youth: A Qualitative Analysis of their Experiences

The sexual health problems experienced by homeless youth bring into question their use of available sexual health services. Using a qualitative typological analysis, this study aims to identify sexual health services utilization profiles for homeless youth, and to understand the role of the homeless experience on the utilization of sexual health services. Individual interviews were conducted with 33 homeless youth (17 men, 16 women) between 18 and 25?years of age. Typological analysis identified four profiles: (1) a targeted use of sexual health services to determine one’s serological status following a relational change during the homeless experience; (2) a limited use of sexual health services to manage sexual emergencies that arise during the homeless experience; (3) a regular use of sexual health services to avoid the risks associated with the homeless experience; (4) a frequent use of sexual health services to obtain support when engaging in prostitution during the homeless experience. This study shows that the precarious and unstable conditions within the homeless experience incite youth to utilize sexual health services in different ways. These findings point to the importance of rethinking sexual health services to better adapt them to the different utilization profiles of homeless youth.     

Exploring the Ebbs and Flows of Community Engagement: The Pyramid of Engagement and Water Activism in Two Canadian Communities

In this article, we share results from a comparative study exploring the dynamics of community engagement surrounding local water advocacy organizations in two Canadian communities. Although emergent local issues and the perception of crisis triggered some short-term community engagement, social factors such as collective identity, a sense of community, and sense of efficacy appear to be more important for sustaining and deepening engagement. Drawing on the results, we show how the pyramid of engagement, by depicting activist engagement as a multilevel, developmental process, can serve as a useful tool for community engagement scholars and practitioners alike.
