Taphonomy of marine environments has been studied mostly from individual cases. The formation of adipocere, or "grave-wax," is an important indicator of the postmortem interval. In the present paper, the conditions and the timing of adipoceric formation are observed in a series of 15 cadavers recovered at different times, over a period of 433 days, from the same contained environment. Initial foci of adipocere on the subcutaneous tissue of the cadavers were detected as early as 38 days from the time of immersion in cold (10-12 degrees C) sea water. The discrepancies between our findings and previous reports on the correlation between time since death and decomposition stages in marine environments are discussed. 相似文献

Over the past decade, the proliferation of election surveys has worked to undergird the electoral system in Mexico and to make electoral fraud more difficult. In the presidential elections of 1994, significant controversies arose as to survey methodologies, but by the congressional elections of 1997 the fierce debates over methodologies had subsided. Substantively, the surveys confirm the accuracy of the vote count in 1998, allow profiles of voters to be constructed for the three most important parties and mark declines in the support of the once dominant Partido Revolucionario Institucional. 相似文献

Coastal beaches are a source of considerable recreational activity, but are also eroding at a rapid rate. Since beach resources are common property, there is no organized market to determine economic benefits from recreational use. Through a willingness to pay equation for beach use, this article demonstrates how proposed beach renourishment policy can be evaluated within a benefit-cost analysis framework. Benefits are estimated as the incremental willingness to pay per day for a larger beach width which is translated into annualized benefits. Annualize cost of achieving maximum benefits are calculated from a cost function. Given the existing cost of beach renourishment, it was found that all beaches in Florida that are overcrowded (i.e., had less than 112 square feet per person/day) could be renourished at a benefit-cost ratio greater than unity. In Florida, beach renourishment policy for overcrowded beaches yields more economic benefits than costs. However, this technique does not lend itself to policy analyses of uncrowded beaches that are undergoing considerable erosion. 相似文献

In the current legal atmosphere, any practicing professionals, including police psychologists, may expect to have their decisions
challenged in court. If such a challenge is not met, it may have a disastrous financial and reputational impact for both the
psychologist (and other expert consultant) and the employer or contractor by whom the psychologist has been retained. The
rules for expert witness qualification throughout the nation have been very strongly effected by the introduction of the Federal
Rules of Evidence in 1975 and subsequent case law, particularly theDaubert, Joiner, andKumho Tire Supreme Court decisions. This article examines the history of the development of theDaubert Standard and proposes principles for potential expert witnesses in order to minimize the likelihood of aversive consequences, such
as disqualification or malpractice accusations.

We use a case study of the Landless Workers Movement (MST) in Brazil and the Via Campesina network of which they are part to develop the concept of ‘vernacular rights cultures’. Vernacular rights cultures calls attention to the way in which demands for the right to have rights call on particular cultures, histories and political contexts in a manner that can transform the rights inscribed in constitutions and political imaginaries. What Ranciere (1999) and Balibar (2002) call the democratisation of democracy, we therefore argue, does not just involve a logic of equality and inclusion through which dispossessed groups demand already existing rights. Rather, it also occurs as mobilisations alter the means through which rights are delivered and transform the content and meaning of the rights demanded. 相似文献
