This Special Issue stems from the international symposium, “Child Sexual Abuse Images Online: Confronting the Problem—Research, Policy, Practice,” which was held at Ryerson University in June 2014 with funding from the Social Sciences and Humanities Research Council of Canada (SSHRC). The collection of papers in the Issue focus on child sexual abuse images online from the perspectives of children's mental health, child protection, and law enforcement. The symposium brought together local and international academics, policymakers, child advocates, practitioners, law enforcement officers, child welfare workers, and other key stakeholders who assume various roles and responsibilities in responding to child sexual abuse. Over two days we shared knowledge, experiences, and insights related to the role of technology in child sexual abuse; specifically the implications of child sexual abuse images online. Through presentations, panel discussions, and round-table working group discussions, participants examined and shared current knowledge about child sexual abuse images online, identified key priorities, and determined critical strategies and vital next steps. The five articles in this Special Issue represent those cross-sectoral contributions. We thank the Editors of Child & Youth Services, Dr. Kiaras Gharabaghi and Dr. Ben Anderson-Nathe, for inviting us to develop a Special Issue for this journal based on the presentations made at the 2014 CSAIO Symposium. We also thank our external reviewers through whom all articles in this Issue were subjected to a rigorous blind peer review. 相似文献

Involvement in physically active pursuits, such as sports, contributes to achieving and maintaining good emotional and physical health. The central goal of this article was to examine the longitudinal relationships between participation (i.e., time spent in the activities) in organized and informal sports contexts and motivational beliefs, and factors that might impact these relationships, such as developmental stage and gender. The data for the current study were drawn from the childhood and beyond longitudinal study, which utilized a cohort sequential design with data collected on three cohorts across four waves. The current study sample included 986 European American youth (51 % female), who t were mostly from working- and middle-class families. Self-report questionnaires were used to collect data from the youth about their participation in sports and their motivational beliefs (i.e., value and perceptions of competence) about this activity. Structural equation modeling was used to examine the relationships between participation and motivational beliefs across childhood and adolescence. The results provide some support for a model of reciprocal relationships between participation and motivational beliefs in organized and informal sports activities. These relationships between participation and motivational beliefs did not vary significantly based on developmental stage or by gender. Overall, the findings suggest that participation in organized and informal sports contexts may be fostered by supporting the development of positive motivational beliefs about the activities across developmental periods. 相似文献

In a widely read paper, the United Nations Food and Agriculture Organization, World Bank and others propose systematic property rights formalization as a key step in addressing the problems of irresponsible agricultural investment. This paper examines the case of Cambodia, one of a number of countries where systematic land titling and large-scale land concessions have proceeded in parallel in recent years. Cambodia's experience exemplifies the challenges of the ‘formalization fix’ – the proposition that property formalization constitutes a preferable front-line defense against land grabbing – and highlights formalization's uneven geography as an issue that has yet to generate adequate discussion internationally. Three dimensions of Cambodia's less-than-successful formalization fix efforts stand out: (1) the spatial separation of systematic land titling and agribusiness concessions that emerged during the 2000s and has only recently begun to be addressed; (2) the deployment of property formalization as a means of land grabbing, especially when applied selectively and unevenly; and (3) the political arena of efforts to legitimize ‘state land’. The paper questions the formalization fix as a policy solution, and argues for both greater spatial transparency in property formalization efforts throughout the global South, and greater attention to the problem of unmapped state land in general. 相似文献

This paper analyzes how dynamics between Brazil's right-wing populist government and civil and uncivil organizations affected the role of civil organizations, especially rights-based ones, and Brazil's democratization process. These dynamics contributed to stripping policies of their progressive nature and rejecting the values of diversity, freedom, and equality. Our analysis relies on the inhabited institutions approach to comprehend the role of action, interaction, and meaning in institutionalized spaces. We analyzed two policy fields—gender, sexual, and reproductive rights, and ethnic and racial relations—through documents and in-depth interviews. Our analysis shows that Bolsonaro's government mobilized mechanisms related to institutional changes, the replacement of actors, and their interactions to inhibit civil society organizations' influence in policy formulation and provision and strengthen the participation of uncivil groups, thereby legitimating conservative ideas and discourses, and closing civic space for NGOs with rights-based agendas. 相似文献

The negative externalities of global commodity chains and existing governance gaps have received wide scholarly attention. Indeed, many sectors including forest-risk commodities (FRCs) like soy and beef from Brazil remain largely unregulated. This article analyzes ongoing policy-making processes at European Union level to adopt new regulations for reducing accountability gaps: one regulation of FRCs and one general, cross-sectoral directive on human rights and environmental due diligence. This article draws on and aims to contribute to previous research into foreign corporate accountability, therein analytically distinguishing between input, output, and surrogate accountability. This study shows that new policies will likely be more comprehensive than previous supply chain regulations, while their specific institutional design and stringency are highly contested. More in general, we argue that for hardening corporate accountability, due diligence politics will need to confront important governance challenges that have limited the potential of previous regulations, such as a lack of consequentiality of reporting obligations, weak state monitoring, limited stakeholder involvement, and difficulties to establish legal liability. 相似文献
