The extent of aspartic acid racemization in dentin: a possible method for a more accurate determination of age at death?

In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here.     

Sensitivity of various study technics in blood stains

Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood.     

Fatalities in west Austrian prisons

The purpose of this study is to review 23 causes of death that have occurred in Western-Austrian prisons from 1974 to 1989. The majority of them (11 cases) were due to suicides. Among 9 cases of natural death there was a 25 years old man, who died of an unknown purulent meningoencephalitis. Two drunken prisoners had not been supervised and therefore died of alcohol poisoning. In one case the police jail physician did not recognize an epidural hematoma.     

Social justice as a Holy Grail: The endless quest

This paper gives the author's impressions on the following aspects of justice: desert, equity, equality, need, and intergenerational equity. The author concludes that these different aspects cannot be reconciled but instead must be compromised. An example of such a compromise is provided by a discussion of welfare reform. The author claims that rights are correlative with duties, and that asserting the former has little meaning without specifying the latter. He then discusses justice toward groups rather than individuals. He proposes that maintaining cultural variety in the presence of a homogeneous superculture is a major problem of the contemporary world. The paper concludes with a discussion of various forms of power, particularly the integrative power that people acquire over each other by virtue of ties of loyalty and identity.     

Bicommunalism in Northern Ireland

Northern Ireland is a bicommunal society in which Protestantsare numerically dominant; Roman Catholics constitute virtuallyall of the remaining population. On the island as a whole, Protestantsare heavily outnumbered; the Republic of Ireland (the "South")has a population that is about 96 percent Catholic. Social segregationof the two northern communities is relatively distinct, andthere is little crosscutting between groups that might lessenbicommunal conflict. A reciprocal relationship exists betweenthe social system and political structures. Northern Irish politicalinstitutions followed the Westminster model, which facilitatedthe political exclusion of Catholics and impeded social as wellas political integration. The bicommunal social structure hasimpeded the development of more accommodating political structures.Geographic issues and external linkages compound the politicalproblem. Northern Irish politics can be viewed as a "dual dyad"in which the United Kingdom and the Republic of Ireland arecritical components. Psychological dimensions of Northern Irishbicommunalism further exacerbate the conflict.
