Measuring carbon monoxide content in muscles

A method ist described to determine the CO-content in the tissue of muscles. The prepared tissue is pulverized in a swinging mill at the temperature of liquid nitrogen. Parts of the powder are weighed into headspace vessels. Carbon monoxide ist ejected by a formerly described method and measured gaschromatographically. The Fe-content is determined after an acid disintegration by AAS. Acute intoxications lead to higher CO-contents in heart than in periphere muscles. Chronic exposure to carbon monoxide does not produce these differences.     

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.     

Child's play: The political imaginary of international relations and contemporary popular children's films

Many scholars in International Relations (IR) have drawn from popular films to examine various problématiques that have informed the discipline's main theorisations. As Cynthia Weber remarks, popular films are powerful because they engage in the very ‘serious political work’ of mythologising the ‘truths’ and ‘realities’ which provide the foundation for many of IR's main theoretical envisionings of our world. To date, however, children's films have received very little attention. For the purpose of this paper, three have been isolated: Toy Story (1995), A Bug's Life (1998) and Rescue Heroes: The Movie (2003). Children's films, it can be argued, help to craft and restore certain perspectives for each new generation of young minds during the crucial years when the world is being textualised for the first time. The objective of this paper, therefore, is to read these films as working towards producing and sustaining the power/knowledge that seeks to defend contemporary forms of world order while concurrently extending and disseminating the rule of these forms of world order through the medium of children's popular cinema.     

Relationships between psychosocial development and personality disorder symptomatology in late adolescents

The present study investigated the extent to which psychosocial development through the first five stages of Erik Erikson's theory of personality development is associated with Diagnostic and Statistical Manual (third edition, revised; DSM-III-R) Axis II personality disorder symptomatology in a late adolescent sample of undergraduate students. The Inventory of Psychosocial Development (IPD) and the Personality Diagnostic Questionnaire—Revised (PDQ-R) were administered to a mixed-sex sample of 106 undergraduate students. The results of this research were that IPD scores assessing negative resolutions of the first five Eriksonian developmental stages consistently predicted scores on the PDQ-R composite scale and the PDQ-R impairment/distress index—both measures of overall personality disorder symptomatology. The IPD subscales varied substantially in the extent to which they predicted scores on the 13 PDQ-R subscales that assess symptoms of specific DSM-III-R personality disorders—ranging from the trust vs. mistrust subscale, which predicted scores on 12 of the 13 PDQ-R subscales, to the initiative vs. guilt subscale, which predicted scores on only 6 of the 13 PDQ-R subscales. Implications of these findings for our understanding of the relationship between psychosocial development and psychopathology are discussed in the context of previous research in this area, and suggestions for future research are offered.Received Ph.D. from Temple University.
