A Process for Incorporating Comparative Risk into Environmental Policymaking in Louisiana

The goal of Louisiana's 1990–1991 comparative risk project, also called the Louisiana Environmental Action Plan (LEAP), was to incorporate risk assessment into state environmental planning and policymaking. Scientists, government officials, and citizens were brought together to estimate the relative risk to human health, natural resources, and quality of life posed by 33 selected environmental issues. The issues were then ranked according to their relative estimated risks. It was hoped that this ranking of "comparative risks" would enable state policymakers to target the most important environmental problems and allocate scarce public resources more rationally and efficiently. As a result of the project, the governor issued an Executive Order forming a permanent Public Advisory Committee to continue this type of comparative risk assessment in Louisiana.     

A sea change on the island continent: frameworks for risk assessment,prevention and intervention in child health in Australia

This article overviews prevention and early intervention approaches focusing specifically on their relevance to the health of children and young people in Australia. Australian public health has a sound track record although concealed within the aggregate profile are a number of sub-populations with poorer health indicators. Recognition of this has increased efforts to improve the health of children and young people especially in exploring the impact of social environments within the communities where children are raised. This paper examines emerging research in this area drawing out key lessons and learning from Australian experience in the field of early intervention and prevention in community settings.     

African urban life: Components of satisfaction in Sierra Leone

This comparative study finds relatively high satisfaction with the quality of life in three Sierra Leonean towns, but there are notable differences between men and women and between the towns in which domains support this satisfaction. The standard of living achieved, and the job and income which make it possible, are the most important factors in satisfaction with the quality of urban life, but the limits on women's mobility are indicated by the greater emphasis they place on housing and neighborhood. Dissatisfaction among the relatively advantaged, with their own position and with the country's progress in development, reflects the political disaffection of some members of this group.     

Housing Conditions of Nuclear and Extended Households in the Miami-Fort Lauderdale Area

Arrivals of new immigrants into the south Florida area have put increased pressure on housing markets and fostered renewed efforts to provide more affordable housing. Many view household extension largely as a response to the lack of a sufficient amount of affordable housing. This paper examines the nature, proportion and housing condition of nuclear and extended households in the Miami-Fort Lauderdale area. The study also investigates how the incidence and housing situation of extended households has changed during the period from 1986 to 1990. This study illustrates that extended families in the Miami-Fort Lauderdale area are not uniformly worse off than nuclear families, given ethnicity and income level. While the area's housing problems require attention, some of that attention should be focused on removing institutional barriers to household extension and to providing broader housing choices for minority ethnic groups.     

Will to love,will to fear: the emotional politics of illegality and citizenship in the campaign against birthright citizenship in the US

Anti-immigration activists argue that the broad inclusivity of the birthright citizenship clause of the 14th Amendment is a national security concern that enables criminalized migrant mothers to give birth to citizens who can later harm the US through violence and resource consumption. Seeing this argument as representative of the problem of inclusivity inherent to citizenship in a liberal democracy, this essay asks how the children of undocumented and temporary migrants are constructed as what Mae Ngai calls ‘alien citizens.’ Drawing from Sara Ahmed's affective economy of emotion, I find that affect and emotion figure prominently in how citizens are made ‘alien.’ Specifically love and fear function as pivot points in the anti-birthright citizenship argument, wherein the ‘real citizen’ is ‘willed’ to love and be loved by the nation and to fear the nation's Others. Moreover, the emphasis on national feelings does not evacuate white supremacy or heteronormativity from its imagination of citizenship, but instead displaces these loci of power into feeling and affect. Thus, this essay claims that the birthright citizenship argument illustrates how national love and fear work in tandem to uphold, naturalize, and expand the racial and sexual exclusions inherent to citizenship in a nation-state.     

Topics in Microbial Risk Assessment: Dynamic Flow Tree Process

Microbial risk assessment is emerging as a new discipline in risk assessment. A systematic approach to microbial risk assessment is presented that employs data analysis for developing parsimonious models and accounts formally for the variability and uncertainty of model inputs using analysis of variance and Monte Carlo simulation. The purpose of the paper is to raise and examine issues in conducting microbial risk assessments. The enteric pathogen Escherichia coli O157:H7 was selected as an example for this study due to its significance to public health. The framework for our work is consistent with the risk assessment components described by the National Research Council in 1983 (hazard identification; exposure assessment; dose-response assessment; and risk characterization). Exposure assessment focuses on hamburgers, cooked a range of temperatures from rare to well done, the latter typical for fast food restaurants. Features of the model include predictive microbiology components that account for random stochastic growth and death of organisms in hamburger. For dose-response modeling, Shigella data from human feeding studies were used as a surrogate for E. coli O157:H7. Risks were calculated using a threshold model and an alternative nonthreshold model. The 95% probability intervals for risk of illness for product cooked to a given internal temperature spanned five orders of magnitude for these models. The existence of even a small threshold has a dramatic impact on the estimated risk.
