Influence of vegetation composition on runoff in two simulated green roof experiments

Despite the fact that green roofs are based upon living systems, the majority of published research literature contains little specific information on the contribution of plants to the various functions and properties of green roofs. Furthermore, there has been little investigation of the influence of the composition of vegetation on the physical properties of a green roof system. This paper reviews previously published material that throws light on the role of vegetation composition on green roof function, with particular regard to rainwater runoff. Two experiments at the University of Sheffield, UK, are considered in detail: (a) An outdoor lysimeter experiment that investigated the quantity of runoff from trays containing 100 mm of growing medium and combinations of grasses and forbs, together with bare substrate, and (b) a greenhouse experiment using simulated rainfall to estimate the amount of rainfall intercepted by different vegetation types. In both cases the vegetation ranged from simple monocultures of forbs and grasses through to complex mixtures of both. In both cases, the composition of the vegetation was found to significantly affect both the amount of water retained and released from the system.     

Emotional harm and neglect: the legal response

This paper reports on a study of the extent to which child protection applications brought to the Melbourne Children's Court in Victoria, Australia, were based on emotional/psychological harm or neglect of a child and what factors were presented as evidence of harm or neglect. The study examined records of 208 court‐ordered pre‐trial conferences heard in the court between February and July 2002. What was found was that, although cases involving emotional abuse have increased in terms of child protection applications, they remain cases that are difficult to decide. While in 1998/9 emotional harm was a ground in 25.7% of child protection matters completed in the Family Division of the Children's Court of Victoria, legal decision‐makers are reluctant to make a finding of child abuse in these cases because there is less accuracy in the determination of emotional harm and negligible legal criteria available to guide decision‐making.

Encountering the postmodern: new directions in cultural anthropology

Faisant appel à la littérature d'études culturelles, cet article suggère que la condition de post-modernité crée de nouveaux challenges pour le domaine d'anthropologie culturelle qui vont au delà du problème pourtant significatif de la représentation ethnographique. Explorant le projet post-moderniste comme l'un de ceux qui impliquent une approche particuliere des phénomènes culturels dans une économie globale, l'article pousse les anthropologues à reconcevoir le concept de culture et à explorer les politiques culturelles de la vie quotidienne dans le contexte d'une representation globale du capitalisme.
Drawing upon cultural studies literature, this article suggests that the condition of postmodernity poses new challenges to the field of cultural anthropology that go beyond the (still significant) problem of ethnographic representation. Exploring the postmodernist project as one that involves a particular approach to cultural phenomena in a multinational global economy, the article urges anthropologists to reconceive the concept of culture and explore the cultural politics of everyday life in the context of the global restructuring of capitalism.     

An alternative model for curriculum building in clinical social work education: The California Institute for Clinical Social Work

Summary The growth and development of the California Institute for Clinical Social Work has been parallelled by the enhanced professional contributions of its alumni. Of the 59 graduates of the Institute, ten hold academic positions in top-ranking institutions of higher learning while three more are the chief administrators of social agencies. The remainder devote their time to direct clinical practice.In a recent survey of alumni, all graduates commented in one form or another upon the fact that because of the program, their work was more rewarding personally and was more responsive to clients' needs because of the knowledge and skill that they had gained. The evolution begun in 1974 still continues. This novel program has been elaborated to meet changing needs. Study of its efficacy and flexibility will be pursued as its development proceeds.
