Resident-Defined Neighborhood Mapping: Using GIS to Analyze Phenomenological Neighborhoods

Using a natural quasi-experimental pretest/posttest design, residents in randomly selected homes in a suburb of Los Angeles were surveyed about their perceptions of their neighborhoods with respect to cohesion and sense of community. Responses from the pretest surveys—administered before the construction of a freeway that would bisect the city—were compared to the responses from the posttest survey six years later, administered two years after completion of the freeway. Respondents living adjacent to the new freeway—residents who experienced a fourfold increase in the average decibel levels in their neighborhoods since the freeway opened—reported both a lower sense of community and smaller neighborhood areas as compared to residents not living adjacent to the freeway and as compared to the results from the pretest. The analysis of the data incorporated geographic information system (GIS) software to allow for the analysis of phenomenological neighborhoods—neighborhoods as defined by respondents. This Resident-defined Neighborhood Mapping methodology permitted us to analyze neighborhoods as the respondents outlined them, not as they were preconceived by someone outside the neighborhood. It is suggested that this new methodology may prove useful in advancing the field of neighborhood research by detecting neighborhood-level change that traditional methods may miss.     

Large firms as political actors: A comparative analysis of the chemical industry in Britain,Italy and West Germany

Large firms as political actors are compared in the chemical industry in three countries. In West Germany, co‐ordinated action through the industry associations is important, but firms are developing their own political capabilities. In Italy links with political parties are important, but the operating environment of firms has become less politicised. Britain conforms more to a ‘company state’ model, with the government relations divisions of firms playing a key role. The greatest divergence between the three countries is in terms of relationships with political parties. In general, there is a trend towards greater convergence in government‐business relations in the industry in the three countries, internationalisation being a key factor.     

Depressive Symptoms in Young,Urban Schoolchildren: Environmental,Social, and Cognitive Risk

This study examined relations among stressors, perceived social competence, attributional style, and depressive symptoms in young urban schoolchildren. Data were collected from 85 5- to 11-year-olds, mostly African American, who attended a public elementary school in a low-income urban area. Social competence was examined as a potential mediator, and attributional style was examined as a potential moderator of the relation between stressful life events and depressive symptoms. Separate analyses were conducted by age and gender. For older children and girls, main effects were found for stressful life events as predictors of depressive symptoms. Mediational analyses indicated that perceived peer acceptance served as a mediator of the relation between stressful life events and depressive symptoms for girls. In addition, attributional style moderated the relation between stressors and depressive symptoms in the older children. Together, findings suggest that significant relations exist among stressful life events, social and cognitive processes, and depressive symptoms in young urban children and that these relations are influenced by gender and development.     

The legal role of medical professionals in decisions to withhold or withdraw life-sustaining treatment: Part 3 (Victoria)

This is the final article in a series of three that examines the legal role of medical professionals in decisions to withhold or withdraw life-sustaining treatment from adults who lack capacity. This article considers the position in Victoria. A review of the law in this State reveals that medical professionals play significant legal roles in these decisions. However, the law is problematic in a number of respects and this is likely to impede medical professionals' legal knowledge in this area. The article examines the level of training that medical professionals receive on issues such as refusal of treatment certificates and substitute decision-making, and the available empirical evidence as to the state of medical professionals' knowledge of the law at the end of life. It concludes that there are gaps in legal knowledge and that law reform is needed in Victoria. The article also draws together themes from the series as a whole, including conclusions about the need for more and better medical education and about law reform generally.     

Counterterrorism strategies in the lab

We conduct experiments to test the collective action dilemmas associated with defensive and proactive counterterror strategies. Defensive policies are associated with creating public ??bads' (e.g., a commons) whereas proactive policies are akin to the voluntary provision of public goods. When combined, the inefficiency of collective action is exacerbated, resulting in a situation known as a Prisoner??s Dilemma squared (PD²). Deterministic versus probabilistic equivalent versions of the associated externalities are compared within a laboratory setting. Experimental results reveal that the collective action problem associated with counterterror strategies is deepened in uncertain environments, and is indeed a robust regularity that is not easily overcome; as individuals gain more experience, they become even more self-interested.
