The child's voice in child and family social work decision making: the perspective of a guardian ad litem

This article shows how the voice of the child has come to prominence in decision making, against the background of changes in emphasis between family rights and child protection viewpoints, reflected in 20th-century legislation on family matters. It argues that the role of the guardian ad litem , the historical development of which is charted, is central to the evaluation of the child's views; these are not always straightforward and they must be viewed in tandem with a professional assessment of the child's best interests. The article concludes that the child's voice cannot be the deciding factor in decision making; adults cannot abrogate their responsibility to make reasoned decisions, based both on children's wishes and feelings and on other factors which children, in their immaturity, cannot appreciate.

论平面广告中文字的作用与设计法则

平面广告设计中,文字的作用和设计方法容易被忽视。事实上,文字的设计与安排在平面广告设计中既有传递信息的直观作用,还有思维导向和图形符号表意的作用。文字设计的不考究会破坏整个设计作品的意境,造成无法弥补的缺憾。设计中,将文字视为元素、符号,重视文字自身魅力的展示、版式、本土化,避免文字的附属、装饰地位,才有可能创作出构思巧妙、图文合度,意境深远的平面广告作品。     

文学史的内在逻辑与空间形态写作——评夏冠洲《新疆当代多民族文学史》

联系地域性文化特征和国家意识形态的影响,把新疆文学看作一个多重关系构建的构成部分,是新疆多民族文学史的写作基点。《新疆当代多民族文学史》的写作表明,当代新疆社会文化现实由中国当代社会文化内在逻辑的发展所决定。典型意义的"文化空间形态"需要以过程研究为主,《新疆当代多民族文学史》因此而具有再现和还原新疆当代多民族文学事实真实的写作特点。

‘There Isn't Supposed To Be a Speaker Against!’ Investigating Tensions of ‘Safe Space’ and Intra‐Group Diversity for Trade Union Lesbian and Gay Organization

Trade union engagement with the continuing inequalities facing minority groups has been one of the guiding principles of attempts to re‐energize the labour movement in recent years. This article focuses on attempts by six British trade unions to create and maintain separate organizational ‘spaces’ for their lesbian and gay members. Through consideration of group representation within a union framework, the strategy of separate organizing and the complications of representing a diverse membership, this article considers issues of intra‐group diversity and ‘safe space’ for this particular group of members. It concludes that the recognition and actualization of the internally diverse lesbian and gay constituency will be important in the long term for trade unions seeking to renew their pool of potential activists.

Learning to play chess: How to make sense of a politics of representation with people in poverty

Despite the growing involvement of people in poverty in social policy, their participation does not necessarily take place on a par with policymakers, as the latter often do not really embrace their demands for social justice. It is, therefore, argued that social work has a role to play in the process of merging knowledge of people in poverty with that of policymakers and other stakeholders by representing their perspectives in public debate. By drawing on an in‐depth qualitative research of five “Associations where People in Poverty Raise their Voice” (Belgium), the complexity of the direct participation of people in poverty in such a politics of representation is analyzed, as well as the different roles social work practitioners can take on in dealing with this complexity. Here, two roles are distinguished: “a guardian of collective and transformative elements”; and “a strategical chess player.” We conclude that practitioners need to reflect critically on participatory premises and practices and consider whether these strategies actually contribute to societal change. However, the ideal of parity of participation entails that such strategic considerations should always be collaboratively discussed with people in poverty.
