- This paper explores the institutional and political dynamics of the Business Council of Australia (BCA), a unique form of big business association which relies on the active involvement of its one hundred or so CEO members. The paper argues that associations such as the BCA confront a range of serious institutional problems in their attempts to wield political power, or more modestly perhaps, policy influence. First, they confront a disconnect between ‘structural’ and ‘instrumentalist’ articulations of business power. The key source of business power resides in business control over the economy and the investment process, a form of power wielded at the company level not at the level of business associations. When engaged in instrumentalist or overt forms of political activism, the BCA also confronts serious collective action problems. It is also argued that the influence of the BCA seems to have declined over time and that this can partly be traced back to declining CEO commitment rooted in changing institutional and structural dynamics in the corporate world.

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

Extent, trends, and perpetrators of prostitution-related homicide in the United States 总被引:1,自引:0,他引:1

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
