Social security in a globalizing world

The main burden of the paper is to argue for enlarging both the concept and the coverage of social security, especially in developing countries, to address the twin problems of "deficiency" and "adversity". The two parts of this enlarged concept of social security are Basic Social Security (BSS) and Contingent Social Security (CSS). To strengthen the argument, lessons have been highlighted from the historical experience of Western countries, where the State played a leading role. Having argued for the extension of BSS, the paper also deals with the extension of CSS. This is best done through the informal economy, which employs a large majority of workers in developing countries. While the primacy of the State has been highlighted, the paper develops a typology of various social security models that could be used to study and understand the existing arrangements as well as the potentialities for extension.     

Psychosocial Interventions for Maltreated and Violence-Exposed Children

Child sexual, physical, and emotional abuse as well as child neglect and domestic violence, community violence, and Childhood Traumatic Grief may result in significant and long-lasting emotional and behavioral difficulties. This article reviews randomized controlled studies that have assessed child mental health outcomes for maltreated and violence-exposed children. Key points of this review include the following: (1) maltreated and violence-exposed children typically experience more than one of these types of traumas; (2) effective psychosocial treatments are available to address Posttraumatic Stress Disorder (PTSD), depression, anxiety, and behavioral problems in these children; (3) it is likely that treatments which effectively reduce mental health symptoms in children exposed to one type of child maltreatment or violence exposure will also be effective for other or multiple types; and (4) mental health outcomes are not the only important outcomes to address in future treatment or intervention efforts. These future directions for treatment intervention research are addressed.     

Knowledge representation by schemata in financial expert systems

This paper introduces the notion of knowledge structuring by schemata. A schema is a chunk of knowledge which generalizes the idea of functional dependence between pertinent concepts (objects). The rules are closely related to the schemata. Moreover the schemata are organized in a hierarchical network which takes into account the relative importance of the concepts. Examples are given in the financial field and the consequences with regards to knowledge engineering are discussed.     

The Social Impact of Industrial and Resource Development on Local Communities: A Survey of Residents' Views

This paper describes the results of two surveys of public attitudes, perceptions, and expectations regarding large-scale energy development projects in the Latrobe Valley, Victoria. A baseline survey was conducted in 1974, before plans for a massive increase in planned energy generation for the Valley had begun to be instituted (projected to inject 440MW per year additional capacity to the year 1989, compared with an average annual increase of 52MW per year which characterized the period from 1921 to 1974 (State Electricity Commission of Victoria 1981)) and before construction commenced in 1977, on the first of two 2000MW power stations, located at Loy Yang, six kilometres from the town of Traralgon in the Latrobe Valley, Victoria. A subsequent survey was undertaken in 1981, with construction well-advanced on the first two 500MW units. The community studies represent part of a major project concerned with impact assessment of new industrial and resource projects in settled (as distinct from isolated) regions of Australia.     

The regulation of family involvement in deinstitutionalization

Conflicting legal, administrative, and professional policies surround family involvement in the deinstitutionalization process. This article addresses these discrepancies and makes recommendations for developing effective and consistent channels of policy among social workers and other helping professionals.     

Estimators of percentiles based on absolute loss

Estimators of percentiles of location and scale parameter distributions are optimized based on Pitman closeness and absolute risk. A median unbiased (MU) estimator and a minimum risk (MR) estimator are shown to exist within a class of estimators, and to depend upon the medians of two completely specified distributions.     

Modelling change in cognitive understanding with finite mixtures

Psychological theories often posit the existence of several different states. Individuals are viewed as belonging to one of the states at a given age, but with development pass to another state. A main problem in evaluating such theories is representing the transition from one state to another over age. A stochastic transition framework is proposed which should be useful in many different settings. The model is illustrated with data from a cognitive development task.
