Encouraging Pollution‐Free Energy: The Diffusion of State Net Metering Policies*

Objective. As the price of energy swells, renewable energy sources will serve as important alternatives to fossil fuels. Identifying what influences a state to adopt a policy that promotes the construction of renewable energy sources is an important step toward understanding the nature of our future energy supplies. Methods. Using an event‐history analysis, we examine three competing diffusion explanations on the likelihood of a state adopting net metering. Results. We find that regional policy diffusion influences the likelihood of a state to adopt a net metering policy. Conclusions. The results suggest that states are learning from one another and that the EPA's regional offices help facilitate this diffusion.     

Inter‐agency Cooperation and New Approaches to Employability

This article examines the role of inter‐agency cooperation, which is one form of ‘partnership’, in new approaches to employability in the UK. The article articulates a ‘model for effective partnership working’ on employability. This model is applied first in a general review of employability policy and then to discuss case study research on the recent ‘Pathways to Work’ and ‘Working Neighbourhoods’ pilots. It is argued that successful partnerships need a clear strategic focus based on a necessity for inter‐agency cooperation and institutional arrangements that allow for shared ownership, trust and mutualism, and flexibility in resource‐sharing. While some of these factors are apparent in UK employability services, an over‐reliance on contractualism and centralized organizational structures may undermine partnership‐based approaches. Many of the success factors associated with effective partnership working appeared to be in place, even though the role of the Public Employment Service was fundamentally different in each case (as a key actor in implementing the first pilot, but largely withdrawing from the implementation role in the second). The article concludes by outlining the relevance of this model and the case study findings to discussions of the future development of employability policies and related partnership working.     

An Integrated Physical Dispersion and Behavioral Response Model for Risk Assessment of Radiological Dispersion Device (RDD) Events

A radiological dispersion device (RDD) or "dirty" bomb is a conventional explosive wrapped in radiological material. Terrorists may use an RDD to disperse radioactive material across a populated area, causing casualties and/or economic damage. Nearly all risk assessment models for RDDs make unrealistic assumptions about public behavior in their health assessments, including assumptions that the public would stand outside in a single location indefinitely. In this article, we describe an approach for assessing the risks of RDD events incorporating both physical dispersion and behavioral response variables. The general approach is tested using the City of Pittsburgh, Pennsylvania as a case study. Atmospheric models simulate an RDD attack and its likely fallout, while radiation exposure models assess fatal cancer risk. We model different geographical distributions of the population based on time of day. We evaluate aggregate health impacts for different public responses (i.e., sheltering-in-place, evacuating). We find that current RDD models in use can be improved with the integration of behavioral components. Using the results from the model, we show how risk varies across several behavioral and physical variables. We show that the best policy to recommend to the public depends on many different variables, such as the amount of trauma at ground zero, the capability of emergency responders to get trauma victims to local hospitals quickly and efficiently, how quickly evacuations can take place in the city, and the amount of shielding available for shelterers. Using a parametric analysis, we develop behaviorally realistic risk assessments, we identify variables that can affect an optimal risk reduction policy, and we find that decision making can be improved by evaluating the tradeoff between trauma and cancer fatalities for various RDD scenarios before they occur.     

The effect of habitual exercise on respiratory- muscle function in older adults

Older adults' participation in habitual exercise might be affected by alterations to respiratory mechanics such as decreased respiratory-muscle strength. This reduction can cause a decrease in efficiency of the ventilatory pump, potentially compromising exercise participation. This research examined the role of habitual exercise in respiratory-muscle function and the associated implications for exercise performance. Seventy-two healthy older adults (36 men, 64.9 +/- 8.6 years, 177.2 +/- 8.4 cm, 82.5+/- 11.9 kg; 36 women, 64.9 +/- 9.5 years, 161.7+/- 6.4 cm, 61.6 +/- 9.2 kg) undertook respiratory-function and walking-performance tests. Active men and women achieved higher scores than their inactive counterparts for all tests except spirometry, where no differences were evident. The results indicate that a significant amount of the elevated fitness level might be accounted for by increased endurance capacity of the inspiratory muscles. Inactive older individuals might be at risk for inadequate respiratory-muscle strength, so interventions should be considered.     

Temporal Variability and Ignorance in Monte Carlo Contaminant Bioaccumulation Models: A Case Study with Selenium in Mytilus edulis

Although the parameters for contaminant bioaccumulation models most likely vary over time, lack of data makes it impossible to quantify this variability. As a consequence, Monte Carlo models of contaminant bioaccumulation often treat all parameters as having fixed true values that are unknown. This can lead to biased distributions of predicted contaminant concentrations. This article demonstrates this phenomenon with a case study of selenium accumulation in the mussel Mytilus edulis in San Francisco Bay. "Ignorance-only" simulations (in which phytoplankton and bioavailable selenium concentrations are constant over time, but sampled from distributions of field measurements taken at different times), which an analyst might be forced to use due to lack of data, were compared with "variability and ignorance" simulations (sampling phytoplankton and bioavailable selenium concentrations each month). It was found that ignorance-only simulations may underestimate or overestimate the median predicted contaminant concentration at any time, relative to variability and ignorance simulations. However, over a long enough time period (such as the complete seasonal cycle in a seasonal model), treating temporal variability as if it were ignorance at least gave a range of predicted concentrations that enclosed the range predicted by explicit treatment of temporal variability. Comparing the temporal variability in field data with that predicted by simulations may indicate whether the right amount of temporal variability is being included in input variables. Sensitivity analysis combined with biological knowledge suggests which parameters might make important contributions to temporal variability. Temporal variability is potentially more complicated to deal with than other types of stochastic variability, because of the range of time scales over which parameters may vary.     

STATUS POLITICS AND THE POLITICAL AGENDA OF THE CHRISTIAN RIGHT

Status politics has been used by scholars to explain social protest movements, particularly those that have been right-wing in orientation. In recent years, some scholars have placed the Christian Right within the context of status politics, while others have suggested it is erroneous to do so. This article examines the applicability of status politics to the Chrisitan Right from the perspective of the political agenda the movement has pushed in the Congress. The argument is that status politics fails to explain adequately the moral, nonsymbolic, and "offensive" dimensions of the Christian Right.     

Educational Attainment and Stability in Long-Term Foster Care

SUMMARY. This paper explores the relationship between the reading attainment of a group of 8–14 year olds in long-term foster care and factors in their histories and current home environments. The findings suggest that children's early histories before entry to care may have an effect on their educational attainment in middle childhood. Some amelioration of early childhood experience may be found in a stable foster home placement which has an expectation of permanence. The type of permanent placement seems less important than the expectation of stability. There was no difference in progress between children where the eventual outcome might be adoption or custodianship and those who would remain foster children. Of especial interest was the fact that the foster children's educational attainment was not related either positively or negatively to contact with their birth parents.     

WHOSE CIVIC COMMUNITY? TESTING ALTERNATIVE HYPOTHESES OF THE RELATIONSHIP BETWEEN CIVIC COMMUNITY AND RACIAL INEQUALITY IN ARREST RATES

This analysis extends prior research on racial inequality in arrest rates by testing opposing hypotheses derived from the civic community tradition in sociology. One interpretation of this perspective suggests that communities with a locally-oriented economic infrastructure, an abundance of civic institutions, and civically engaged citizens should exhibit lower racial disparity in arrest rates. On the other hand, recent writings exposing a potential “dark side” of social capital suggest that civic community may exacerbate such racial disparties. Using spatial regression models to analyze data from nearly 1,800 U.S. counties, the current analysis examines these competing hypotheses regarding the effects of civic community. Results suggest mixed support for both the traditional and “dark side” predictions. Implications for theory and empirical research are discussed.
