Testing for AIDS: uses and abuses

In response to the public outcry for mandatory testing for AIDS, this Article explores the major issues concerning the identification of persons with AIDS in society. The Article first studies testing procedures and the purposes behind them to determine if a call for mandatory testing of the general populace would better achieve society's objectives for identifying individuals with AIDS. Concluding that testing should not be required of the population as a whole, the Article then explores whether testing should be required of certain subpopulations which society perceives as likely to have or to spread the disease. In this context, too, the Article concludes that mandatory testing would be unwarranted, and that funds proposed for mandatory testing would be put to better use in education and universal precautions to prevent the further spread of AIDS.     

Political instability in Africa: A rent-seeking approach

The foregoing analysis developed the paradigm of self-interest motivated revolutionary activities. In effect, the construct presented differs from the by-product theory developed by Tullock only in its specific modeling of government-created rents as the engine which drives the violent political behavior. The empirical test of the positive relationship between rent creation by the government and the amount of destabilizing political activity yields strong support for the structuring of politically destabilizing activities as rent-seeking in nature. It is the authors' hope that further empirical investigation and a more general and rigorous modeling of revolution as a rent-seeking activity will become an important part of the literature in public choice.Finally, some policy implications should be discussed. The policy emphasis for the governments of Africa countries should be on opening the economy to competition. Instituting programs to make the economic system more accessible to all segments of society would result in reduced opportunities for rent-seeking. Reducing rent-seeking should result in increased political stability. A reduction in government market intervention would also reduce the costs of government regulations on individual entrepreneurs inducing them to increase their participation in economically productive activities. Taken together the result would be increased political stability and higher rates of economic growth.     

Assessing the health behaviors of African American emerging adults

The purpose of this article was to assess the overall health behaviors of African American emerging adults who live in a Midwestern city. Two hundred participants, ages 18-25, completed a 129-item survey. Results indicate that African American emerging adults are engaged in relatively healthy behaviors (i.e., physical activity, low substance use). The results also showed that within the emerging adult developmental period, there are differences in behavior for those who are in the younger (18-20) versus those that are older (21-25) in the developmental period. Limitations, future research, and implications for practice will also be discussed.     

On the looting of nations

We develop a dynamic discrete choice model of an unchecked ruler making decisions regarding the development of a resource rich country. Resources serve as collateral and facilitate the acquisition of loans. The ruler chooses either to stay in power while facing the risk of being ousted, or loot the country??s riches by liquefying the resources through lending. We show that unstructured lending from international credit markets can create incentives to loot the country; and an enhanced likelihood of looting causes greater political instability, and diminishes growth. Using a treatment effects model, we find evidence that supports our predictions.     

The effect of zinc chloride, humidity and the substrate on the reaction of 1,2-indanedione-zinc with amino acids in latent fingermark secretions

Anecdotal evidence from forensic practitioners and studies conducted under controlled conditions have indicated that the reaction between 1,2-indanedione and the amino acids present in latent fingermark deposits is highly susceptible to ambient humidity. The addition of catalytic amounts of zinc chloride to the 1,2-indanedione working solution--usually in the order of 1:25 to 1:4 molar ratio (indanedione:zinc)--significantly improves the colour and luminescence of fingermarks treated under dry conditions but appears to have a negligible effect on fingermarks treated in humid environments. The results presented in this paper confirmed that zinc(II) ions added to the 1,2-indanedione working solution act as a Lewis acid catalyst, stabilising a key intermediate during a rate-limiting hydrolysis step. Furthermore, studying the reaction using a chromatography-grade cellulose substrate method previously reported confirmed that cellulose substrates play a major role in facilitating the indanedione-amino acid reaction by acting as a surface catalyst in the early stages of the reaction and by directing the formation of the desired luminescent product (Joullié's Pink).
