Detection of diatoms in blood by a combination of membrane filtering and chemical digestion

An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically.     

Der Europ?ische Gerichtshof als Motor der Integration: Eine akteursbezogene Erkl?rung

For nearly five decades, the European Court of Justice (ECJ) has developed a decisively pro-European case law and has become the ??engine of integration??. Institutional explanations shed light on the Court??s room for manoevre. They have to be complemented by actor-centered explanations that shed light on the judges?? motives of action. The explanation offered by the following paper is unfolded in two steps. In the first one, the article describes idiosyncrasies of the European law discourse that already shaped the judges before they were appointed. The analysis of the idiosyncrasies corresponds to a scepticism towards the idea of national sovereignty, a belief in the necessity of creative and idealist, law-augmenting judges and a dominance of output-oriented legitimization strategies. In a second step, the article shows that in the sociological sense the ECJ judges constitute a group. While the individual judges share an understanding of the aims and functions of European law, the group develops its own identity and grants status to those who perform successful actions with respect to the common integration agenda. This explanation is more realistic than ??rational choice?? explanations which point to the direct and personal benefits that judges derive from their pro-European case law.     

What does “knock and announce” mean? An analysis of<Emphasis Type="Italic">Wilson v. Arkansas</Emphasis> and its progeny

The U.S. Supreme Court held in Wilson v. Arkansas (1994) that the common law “knock-and-announce” principle formed part of the “reasonableness” inquiry under the Fourth Amendment. However, the Court’s opinion gave little guidance as to what would be unreasonable under these circumstances. Some critics expressed concern that this lack of guidance would lead to many variations among lower courts. Other observers discerned a signal that little should be deemed “unreasonable” in the context of “knock and announce.” These criticisms are analyzed through a review of lower court interpretations of Wilson.     

Perceived fairness of drug-testing policies: An application of Leventhal’s principles of procedural justice

Employees rate the fairness of organizational policies by applying principles of distributive and procedural justice. Using Leventhal’s (1980) Principles of Procedural Justice, the current study surveyed 279 upper-level college and graduate students to determine the impact each principle has on support for drugtesting policies. The results support the hypothesis that drug-testing programs that violate these principles are viewed as unfair.

Testing a Model of Resistance to Peer Pressure Among Mexican-Origin Adolescents

This study examined the factors associated with resistance to peer pressure toward antisocial behaviors among a sample of Mexican-origin adolescents (n=564) living in a large Southwestern city in the U.S. A model examining the influence of generational status, emotional autonomy from parents, and self-esteem on resistance to peer pressure was tested independently for boys and girls. Gender differences emerged in the factors that influenced resistance to peer pressure. Results indicated that resistance to peer pressure was influenced by generational status and emotional autonomy from parents for both boys and girls. However, self-esteem was found to influence resistance to peer pressure only for boys.Mayra Y. Bámaca is a graduate student in Family and Human Development at Arizona State University. Her research interests include adolescent development among ethnically diverse populations, the influence of contextual factors in development, parenting adolescents, and resiliency among Latino adolescents and their families. This work was based on the master’s thesis of the first author.Adriana J. Uma?a-Taylor received her Ph.D. from the University of Missouri-Columbia and is currently an Assistant Professor of Family and Human Development at Arizona State University. Her research interests include ethnic identity formation during adolescence and resilience among Latino adolescents and their families.This study was supported, in part, by a grant to the second author from the Fahs Beck Fund for Research and Experimentation of the New York Community Trust.
