Child protection services and parental reactions to children's behaviour

A commonly used expression in child protection is the term 'physical abuse'. This paper consists of a quantitative and qualitative analysis of a 100% sample of 'physical abuse' child protection cases drawn from research in an Australian state child welfare agency, which shows that about 90% of these concerned incidents in which parents used physical punishment to control children. Resulting physical harms to children (where they occurred) were generally of a very minor nature. The paper examines these results in the light of research findings in the UK and Australia on patterns of physical punishment used by parents to control children. Such findings suggest that those child rearing practices that make frequent and systematic use of physical punishment are located largely amongst lower social class parents, who believe that such practices are an essential and normal component of effective parenting behaviour. One interpretation of child protection services in respect of these cases is that they are concerned primarily with the normalization of child rearing practices. The paper concludes with a discussion of the limited impact of the Swedish anti-spanking law of 1979, which appears to have only reduced the use of physical punishment by those parents who may not necessarily have believed in such measures in the first place. However, legislation of this nature has the potential to criminalize a substantial sector of the population, but at least state intervention under the aegis of a specific criminal law provides a clearer mandate than does intervention under much looser, broader and subjectively interpreted child protection legislation.     

Religion, Meaning, and Prejudice

Links between religion and prejudice have been interpreted to suggest that religion can both reduce and exacerbate prejudice. Here, the analysis of religion as a meaning system illuminates how religion can affect intergroup attitudes. Traditional psychological perspectives on religion and prejudice are summarized, followed by a discussion of religion and prejudice in cross-cultural and cross-religious contexts, involving varying target groups. Next, we explore possible explanatory mechanisms by proposing how four levels of meaning associated with religion—cognitive, motivational, societal, and intergroup—may both promote and attenuate prejudice. Finally, additional factors that might facilitate the paradoxical coexistence of religious egalitarian intentions with prejudiced attitudes are considered, and we speculate about the potential for religious groups to reduce prejudice within their adherents.     

An Exposure‐Response Threshold for Lung Diseases and Lung Cancer Caused by Crystalline Silica

Whether crystalline silica (CS) exposure increases risk of lung cancer in humans without silicosis, and, if so, whether the exposure‐response relation has a threshold, have been much debated. Epidemiological evidence is ambiguous and conflicting. Experimental data show that high levels of CS cause lung cancer in rats, although not in other species, including mice, guinea pigs, or hamsters; but the relevance of such animal data to humans has been uncertain. This article applies recent insights into the toxicology of lung diseases caused by poorly soluble particles (PSPs), and by CS in particular, to model the exposure‐response relation between CS and risk of lung pathologies such as chronic inflammation, silicosis, fibrosis, and lung cancer. An inflammatory mode of action is described, having substantial empirical support, in which exposure increases alveolar macrophages and neutrophils in the alveolar epithelium, leading to increased reactive oxygen species (ROS) and nitrogen species (RNS), pro‐inflammatory mediators such as TNF‐alpha, and eventual damage to lung tissue and epithelial hyperplasia, resulting in fibrosis and increased lung cancer risk among silicotics. This mode of action involves several positive feedback loops. Exposures that increase the gain factors around such loops can create a disease state with elevated levels of ROS, TNF‐alpha, TGF‐beta, alveolar macrophages, and neutrophils. This mechanism implies a “tipping point” threshold for the exposure‐response relation. Applying this new model to epidemiological data, we conclude that current permissible exposure levels, on the order of 0.1 mg/m³, are probably below the threshold for triggering lung diseases in humans.     

Rough-cut capacity planning for remanufacturing firms

Capacity planning is a critical element of any successful production planning and control system. A method of rough-cut capacity planning is developed, based on the bill-of-resources approach, that can be used to plan for capacity required for firms in a remanufacturing including overhaul repair operations environment. The modified bill-of-resources approach developed takes into account two major stochastic elements inherent in this environment; probabilistic material replacement factors and probabilistic routing files. A detailed example from an actual repair overhaul operation is presented to illustrate the technique.     

Some extensions and applications of Kriz's (1972) urn model

A summary of Kriz's (1972) paper concerning an urn model for the PMP distribution is given. Extensions of the model are made, considering cases in which the urns are not drawn from independently. Possible applications of the extended model in some epidemiological situations are suggested, and a simple computer algorithm for simulating the distribution is given. Results of a simple simulation based on May's (1986) paper are given.     

Emergency Planning for Hazardous Industrial Areas: A Brazilian Case Study

One of the characteristics of modern industrial development is the emergence of a new typology of accidents whose effects can be spread, in space as well as in time, well beyond the borders of the installations where they occur, sometimes impacting the local population and the environment in a catastrophic fashion. This is the result of a number of factors that have changed the risk profile of modern industrial activities. For a number of reasons, the developing countries have proved to be more vulnerable to industrial disasters. Three of the most catastrophic industrial accidents—Bhopal, San Juan de Ixhuatepec, and Cubatão—occurred in developing countries, claiming thousands of lives. During the 1970s and 1980s the higher degree of public visibility of industrial hazards as a result of serious accidents, led to the creation, especially in the more industrialized countries, of regulations for greater control over industrial activities, either by means of new laws or by updating existing legislation. Some of these regulations were designed to improve the response to accidents with potential impacts outside the industrial sites. This article attempts to describe the current status and identify the shortcomings of off‐site emergency planning for hazardous industrial areas in Brazil. The most important problems are the lack of specific legislation and the absence of awareness and active participation of public authorities. The experience of an off‐site emergency planning process for a Brazilian industrial area is presented. This experience illustrates how difficult it is to prepare and implement emergency planning processes in an industrializing country.
