The Olson ratio and indirectly endogenous rent

Public Choice - We consider an economy where the rent value depends indirectly on value-adding investment of agents (thus indirectly endogenous) and the win-probability is a function of rent...     

Scanning electron microscopy: application in the identification of diatoms in cases of drowning.

A simple and rapid method is described for processing organ and water samples for the identification of diatoms so that they can be studied and recorded for taxonomic and diagnostic purposes. Samples are treated with concentrated nitric acid; the fluid obtained is centrifuged, and its sediment is dried, coated, and examined under the scanning electron microscope. The method does not alter the morphology of diatoms and allows the study of freshwater and seawater species present in the organs of bodies found in the water, making possible the diagnosis of drowning under specific conditions.     

Trade union behaviour and inter-regional variations in unemployment rates

An important problem in the political economy of the UK is that the disparity of unemployment rates across its regions is much more marked than the corresponding dispersion of wage rates. One possibility is that this is due to the attitude of trade unions to their members in different regions. If unions wish to preserve parity between members in different regions then they will value wage equality between regions over and above wage levels. This may then persuade them to overlook inter-regional productivity differences in setting wages. The price that low-efficiency regions will then pay for this desire for wage equality is higher unemployment rates.Much of the research for this paper was carried out while the author was visiting the Trade Union Economics Research Institute (FIEF), Stockholm in 1989. An earlier version of this paper was presented at a seminar there and the author is gratefully to Villy Bergstrom, Paul Chen, Douglas Hibbs, Eva Udden-Jondal and other institute members for several useful comments. Comments from Kevin Lee, John Spencer and an anonymous referee have also substantially improved the paper. The usual disclaimer applies.     

Sexual harassment in student residences: A response to DeKeseredy and Kelly's study

Research data from a recent study of sexual harassment in single student residences are provided as confirmation of DeKeseredy and Kelly's national study. The implications of data confirming the consistency of gender differences in attitudes towards and perceptions of unwanted sexual experiences are discussed. Future research in sexual harassment should focus on evaluating preventive education programmes and on operationalizing contextual factors that support sexual harassment.
