Investigating Residential History Using Stable Hydrogen and Oxygen Isotopes of Human Hair and Drinking Water

The relationship between isotopic signals in human hair and geographic region has potential forensic applications for identifying unknown individuals' place of recent residence. This study analyzes δ²H and δ¹⁸O isotopes in residential tap water and bulk hair samples from 17 volunteers representing 12 locations in Ontario, Canada. There is a strong correlation (R² = 0.9) between δ²H and δ¹⁸O values of the water samples. In contrast, the δ²H and δ¹⁸O values of the hair samples are weakly correlated (R² = 0.3), and the greater variability in the data is linked to dietary factors. This study demonstrates that the δ²H and δ¹⁸O values of hair and drinking water can be used to help identify potential place of residence in forensic cases, particularly in relation to proximity to large bodies of water such as the Great Lakes, but interpretations are complicated by the contribution of both water and diet to δ²H and δ¹⁸O values in hair.     

Super-optimizing china: reunification as an example

Whereas political issues and problems in China are complicated, efforts to “super-optimize” are essential and can be fruitful. The reunification issue is discussed to illustrate even highly politicized problems in China are amenable to super-optimum solutions. At the moment, some reunification options have been proposed: KMT-CCP negotiation on equal footing; KMT's military takeover; CCP's military takeover; the “one country, two systems” formula, convergence by democratization, and incremental convergence through trading and communication. Yet, neither parties find the alternatives desirable in terms of optimal satisfaction. By applying SOS rule # 2 (finding items that will provide large benefits to one side but only small costs to the other side), # 5 (combining the conservative and liberal alternatives where they are not mutually exclusive), and # 6 (removing the source of the conflict), reunification and democratization are made feasible and all parties concerned are better off. The specific proposals are that Taiwan should introduce a wholesale buy-out scheme that costs US$30 billion, that a new republic be established, and that legislative powers should be shared among the majoritarian and non-majoritarian institutions. Together, these arrangements could ensure stability and result in democratization.     

Toward 2000 in policy analysis

Looking back over the 20th century and especially over the past 40 years from 1950 to 1990, one can observe various trends in public policy substance and the study of public policy.     

Criminal justice decision making as a stratification process: The role of race and stratification resources in pretrial release

Our purpose is to bridge the criminal justice and stratification research literatures and to pursue the argument that homologous structural principles stratify allocation processes across central institutions of American society. The principle observed here in the making of bail decisions, as in earlier studies of the allocation of earnings, is that stratification resources operate to the greater advantage of whites than blacks. The operation of this principle is established through the estimation of covariance structure models of pretrial release decisions affecting 5660 defendants in 10 federal courts. Education and income are treated in this study as observed components of a composite construct, stratification resources, which works to the greater advantage of whites. Prior record is also found to operate to the greater advantage of whites. Two further variables, dangerousness and community ties, increase bail severity among blacks and whites. While the effect of community ties has been legally legitimized since the Bail Reform Act of 1966, the effect of dangerousness was not so legitimized until the Bail Reform Act of 1984. However, because our data precede the latter act, they confirm that this act simply reinstitutionalized earlier practice. Meanwhile, our race-specific findings may explain why although this and earlier studies find negligible main effects of race on criminal justice outcomes, black Americans nonetheless perceive more criminal injustice than do whites. In the criminal justice system, as in other spheres of American society, whites receive a better return on their resources, but our findings that the statutory severity of the offense and dangerousness work to the relative disadvantage of white defendants challenges conflict and labeling theory's one-dimensional characterization of black defendant disadvantage.
