This paper takes the opportunity of the current child welfare system change in Ireland to promote the value of learning from history to better understand the interface between family support and child protection. The paper draws from the histories of child protection and family support to illuminate the commonalities and differences that have come to define the two practices. Using findings from two historical studies – one on family support and the other on child protection – the paper demonstrates the unique features and the many integrated elements of family support and child protection in Ireland. It is argued that students and practitioners need to be provided with a stronger sense of the historical developments that have shaped the present. This will enable comprehension of the complex context within which current relations between ‘protection’ and ‘support’ are negotiated and help to avoid operating in a vacuum of a present only viewpoint. The paper concludes with reference to the need for students and practitioners to navigate the complex relationship between family support and child protection at practice, policy and organizational level through a well‐informed knowledge of the historical as well as the present context.  相似文献

Repeatedly, adequacy, performance and quality of Ethics Committees that oversee medical research trials are being discussed. Although they play a crucial role in reviewing medical research and protecting human subjects, it is far from clear to what degree they fulfill the task they have been assigned to. This eventuates in the call for an evaluation of their activity and, in some places, led to the establishment of accreditation schemes. At the same time, IRBs have become subject of detailed legislation in the process of the ongoing global juridification of medical research. Unsurprisingly, there is a tendency to understand the evaluation of RECs as a question of controlling their legal compliance. This paper discusses the need for a quality evaluation of IRBs from an ethical point of view and, by systematically reviewing the major ethical guidelines for IRBs, proposes a system of criteria that should orientate any evaluation of IRBs.  相似文献

Urban areas are among the most affected by human activities. In Europe, urbanization has essentially occurred since the end of the 19th century. However, the influence of this dramatic process on aquatic ecosystems has rarely been quantified and analyzed using historical data. In this study, we investigate the evolution of the hydrological system and native aquatic macrophytes in urban areas between the end of the 19th century and the beginning of the 21st century. Four urban areas in Switzerland were chosen for the analyses, Zürich, Basel, Lausanne and Fribourg, and we analyzed the changes in aquatic plant diversity based on the historical and recent floristic data available for the same areas and the same time periods. Our results show that a significant proportion (~30 %) of aquatic habitats has disappeared from the investigated locales during the last 130 years and that the extinction rate of the aquatic plant species is notably higher in the studied cities (28 %) than in Switzerland as a whole (2 %). Thus, between the end of the 19th and the beginning of the 21st centuries, urban development in Swiss cities has prompted a degradation of aquatic habitats that resulted in a significant reduction of the aquatic biodiversity. However, our study shows that urban areas still have the capacity to shelter a large diversity of aquatic organisms, including some of the most threatened species. Thus, it is important to integrate urban areas in the conservation strategies for these species.  相似文献

In recent years, the experience of gender dysphoria has gained public prominence through an explosion of sensationalized interest in the popular media. However, childhood gender dysphoria remains poorly understood and both parents and children often find themselves having to educate professionals around them. This not only creates a sense of disconnect between family and professionals, but also means that social workers can often be unaware of the myriad of competing perspectives that seek to explain gender variance. This review of the literature seeks to provide interested social workers with an overview of gender dysphoria, current research in the field and theoretical paradigms, with a view to promoting understanding and better practice with families in this little understood field.  相似文献

In this article, I underline the continuing intellectual force and rhetorical sophistication of The Communist Manifesto. Both in terms of its explanatory and normative strategy, and in terms of the way it handles the discursive balance between monologue and dialogue, there are, remarkably, still fresh things to say about the way Marx's thought works in this text. The favourable reception given to the Manifesto on its sesqui-centenary is also due to the increased awareness in today's audience of the apparently uncontrollable character of global capitalism, and the deep inequalities and uncertainties it continues to produce. Renewed appreciation of Marx's discursive quality, together with the new-found resonance of aspects of his substantive theories, raises again the question of Marx's status in cultural studies and sociological theory. This study discusses Marx in the light of the whole question of canonicity, and argues that Marx's re-canonization, if that is what is happening, is inevitably double-edged. On the one hand, it is indeed salutary to return to Marx after a prolonged phase of reflexivity, while at the same time the shift towards questions of discourse and affect in the human sciences has itself been responsible in part for sensitizing us to the distinctive effect of Marx's words. If the return of Marx properly radicalizes once more our sense of the point and practice of the human sciences, his legacy is nevertheless unlikely to regain exclusive authority among the plurality of sources for critique and action.  相似文献

This study used polygenic scoring (PGS) to test whether puberty‐related genes were correlated with depressive symptoms, and whether there were indirect effects through pubertal maturation. The sample included 8,795 adolescents from the Avon Longitudinal Study of Parents and Children (measures of puberty drawn ages 8–17 years; of depressive symptoms at age 16.5 years). The PGS (derived from a genome‐wide meta‐analysis of later age at menarche) predicted boys’ and girls’ later pubertal timing, boys’ slower gonadal development, and girls’ faster breast development. Earlier perceived breast development timing predicted more depressive symptoms in girls. Findings support shared genetic underpinnings for boys’ and girls' puberty, contributing to multiple pubertal phenotypes with differences in how these genetic variants affect boys' and girls' development.  相似文献

In sociological action theory, individualistic positions typically criticize practice theoretical approaches in regard to their assumption that individual acts are the products of collective social processes. Instead, individualistic theories generally reduce every action and all social processes to individual actors. This critique on practice theoretical arguments, however, is based on a missing distinction between the cause and the creator of the social meaning of action. Drawing on conceptual distinctions between cause and creator, causality and coordination, and causality and constitution of meaning, I will reject the individualistic critique on theories of practice in this article. Furthermore, I will determine problems of a social theory that is based on an individualistic ontology more generally.  相似文献

In the 1-in port model, every vertex of a synchronous network can receive at most one message in each time unit. We consider simultaneous broadcasting of multiple messages from the same source or from distinct sources in such networks with an additional restriction that every received message can be sent out to neighbors only in the next time unit and never to already informed vertex. We use a general concept of level-disjoint partitions developed for this scenario. Here we introduce a subgraph extension technique for efficient spreading information within this concept. Surprisingly, this approach with so called biwheels leads to simultaneous broadcasting of optimal number of messages on a wide class of graphs in optimal time. In particular, we provide tight results for bipartite tori, meshes, hypercubes, Knödel graphs, circulant graphs. We also propose several open problems and conjectures.  相似文献
