Age-related changes of arachnoid foveae have been described, but objective, quantitative analyses are lacking. A new quantitative method is presented for estimation of change in total volume of arachnoid foveae with age. The pilot sample consisted of nine skulls from the Palmer Anatomy Laboratory. Arachnoid foveae were filled with sand, which was extracted using a vacuum pump. Mass was determined with an analytical balance and converted to volume. A reliability analysis was performed using intraclass correlation coefficients. The method was found to be highly reliable (intraobserver ICC = 0.9935, interobserver ICC = 0.9878). The relationship between total volume and age was then examined in a sample of 63 males of accurately known age from the Hamann-Todd collection. Linear regression analysis revealed no statistically significant relationship between total volume and age, or foveae frequency and age (alpha = 0.05). Development of arachnoid foveae may be influenced by health factors, which could limit its usefulness in aging.  相似文献

Prostitute women have the highest homicide victimization rate of any set of women ever studied. We analyzed nine diverse homicide data sets to examine the extent, trends, and perpetrators of prostitution-related homicide in the United States. Most data sources substantially under-ascertained prostitute homicides. As estimated from a conservative capture-recapture analysis, 2.7% of female homicide victims in the United States between 1982 and 2000 were prostitutes. Frequencies of recorded prostitute and client homicides increased substantially in the late 1980s and early 1990s; nearly all of the few observed pimp homicides occurred before the late 1980s. These trends may be linked to the rise of crack cocaine use. Prostitutes were killed primarily by clients, clients were killed mainly by prostitutes, and pimps were killed predominantly by pimps. Another conservative estimate suggests that serial killers accounted for 35% of prostitute homicides. Proactive surveillance of, and evidence collection from, clients and prostitutes might enhance the investigation of prostitution-related homicide.  相似文献

Reported herein is the suicidal asphyxiation of a young man due to exhaustion of oxygen in the interior of a sealed automobile into which the exhaust emissions were diverted. His blood carboxyhemaglobin concentration was less than 5% saturation. The car was equipped with a catalytic converter and when tested, the exhaust carbon monoxide concentration was 0.01%.  相似文献

Elections to the ‘eleventh convocation’ of the USSR Supreme Soviet took place on 4 March 1984. The process by which the elections took place is examined in detail, from the calling of the election on 16 December 1983, through the nomination, approval and registration of the candidates, to the pre-election meetings with constituents and the poll itself. The level of turnout (99.99 per cent) and the vote in favour of the single list of candidates (99.94 and 99.95 per cent respectively for the two chambers) were in each case the highest in Soviet history; they must, however, be adjusted for the use of ‘absentee certificates’ and an apparent increase in the number of citizens not recorded on the electoral register. Elections without choice, as in the USSR. are not necessarily elections without political significance. Soviet elections appear in fact to perform at least three important functions: legitimation; political communication between regime and citizenry; and political mobilization and socialization. Given the increasing economic difficulties they are likely to face in the later 1980s and beyond, the Soviet authorities may be expected to make even more use of such mechanisms in the future in order to secure acceptance of their decisions without resort to overtly coercive means.  相似文献

This report is intended to clarify the relationship, observed in studies using Kohlberg's moral character model, between the character of college youth and their ideology. With a student sample, measures of three of Hogan's dimensions of moral character (moral judgment, socialization, and empathy) were correlated with sociopolitical ideology defined in terms of several indices of liberalismconservatism. Only the moral judgment dimension (ethics of social responsibility vs. ethics of personal conscience) as measured by Hogan 's Survey of Ethical Attitudes was related to ideology. These results indicate that in accordance with an ethics of responsibility, conservatives have a greater respect for the utility of rules in regulating human conduct and a greater tendency to attribute blame to the individual rather than the societal environment. The study provided no evidence to support conservative charges that radical youth possess delinquent predispositions or liberal and radical claims that conservatives are less concerned about the welfare of others.The research reported in this article was supported by a Faculty Research Fellowship awarded to the author for the summer of 1974 by the Research Foundation of the State University of New York.Received Ph.D. in 1973 from the Department of Psychology at The Johns Hopkins University. Major areas of interest are social psychology and the psychology of social issues.  相似文献

Genetic epistemology is sometimes taken by those unfamiliar with it as a justification for a meritocracy of moral reasoning and the continued oppression of people employing reasoning at lower stages than those who seek to perpetuate the oppression. Whether this interpretation is praised or reviled, it remains erroneous. In particular, this misunderstanding is applied to attempts by genetic epistemologists to apply its insights to the construction of the larger social world. However, a genetic-epistemological politics is really characterized by a concern for maintaining systems permitting free discourse among moral agents. This article outlines the nature of the erroneous interpretations and discusses genetic epistemology's proper application to politics. Stephen chilton is assistant professor of political science at the University of Minnesota at Duluth, where he specializes in conceptual analysis in the fields of comparative politics and political psychology. He is the author ofDefining Political Development (Lynne Rienner Publishers, 1988);Grounding Political Development (Lynne Rienner Publishers, 1991); and (with Shawn Rosenberg and Dana Ward) ofPolitical Reasoning and Cognition: A Piagetian View (Duke University Press, 1988).  相似文献

Kenya's agriculture ministries are reforming their accounting systems and the reform includes computerization. This article examines the impact of computers on accounts and the lessons that can be drawn from Kenya about building computerized accounting systems.
Four propositions emerge about the impact of computers on the accounting systems. First and surprisingly, the initial impact of computers is indirect. Their primary impact is to strengthen the manual accounts which the ministries continue to rely upon. Second, computers promote effectiveness reforms by changing procedures, rather than efficiency reforms by accelerating the throughput of data with existing procedures. Third, computers do not initially promote document processing but do improve data processing. Fourth, computers do promote rudimentary analysis.
One conclusion from the Kenya case is that modular implementation of computerized accounting is helpful. Implementing modules rather than an integrated system means that accounting reforms can begin without waiting for lengthy procedural reforms. Modular implementation also facilitates agency involvement in the design of the system.  相似文献
