The neolignan-type substance 2,4-dimethyl-3,5-bis(4'-methoxyphenyl) tetrahydrofuran is presented as a new forensic marker compound for the peracid oxidation of anethole. It is hypothesized that the formation of a stable intermediary carbocation in the hydrolysis reaction of anethole epoxide is not only responsible for the presence of 1,2-diols (and its esters) and 4-methoxyphenyl-2-propanone (PMP2P) but can also be the cause for the creation of this neolignan impurity due to interaction with anethole itself. Moreover, the applicability of this new forensic marker is demonstrated by its retrieval in clandestinely manufactured 4-methoxyamphetamine (PMA) preparations.  相似文献

This article focuses on a specific aspect of liability insurance that arises out of the latent nature of certain insured events. In particular, it is concerned with the fact that in the interval between the original tort and the claim for damages the standard of care applied by the courts may change. This is the problem of retroactive liability. The article begins by briefly reviewing the legal background to the retrospective application of liability rules. Then it formally addresses the question of how retroactive liability can be reconciled with the goals of tort law and whether retroactive liability is insurable.  相似文献

ABSTRACT

This article argues that the Strategic-Choice Approach (SCA) put forward by Lake and Powell (1999b) can be further developed in two directions. First, the article highlights the challenge posed by the interdependence between actors and their environment. From this it draws two conclusions. A) The SCA approach is most fruitful for synchronic analysis but more challenging to implement in a diachronic research design. B) The interdependence between actors and their environment can be lessened by distinguishing between three types of actor preferences: meta, ranked, and pragmatic-preferences. Second, it argues that the SCA is an ideal framework to combine qualitative and quantitative research designs.  相似文献

Retrospective questions from recent surveys let us estimate rates of church attendance among children and their parents in ten Western democracies throughout most of the 20th century. We combine these time series with standard sources to test competing theories of religious change. Although our attendance estimates affirm the prevalence of religious decline, our statistical tests offer no support for traditional theories of secularization (which link decline to changes in income, education, industrialization, urbanization, and family life). Nor can we attribute much of the observed decline to growth in the welfare state. But increased school spending by governments does reduce church attendance, and this effect is not the result of greater educational attainment. In shaping the content of schooling, governments may strongly influence long-run religious trends.  相似文献

Abstract

This study explored the communication of marketing messages containing traditional, Western festive season symbols and rituals. Specifically, the research sought to understand the decoding of such messages portraying festive season symbols (like Santa Claus and Christmas trees) and rituals, by Afrocentric bottom of the pyramid (BOP) consumers. This qualitative study involved interviews with thirty-one participants in two metropolitan areas in South Africa. The study used a combination of semi-structured interview questions and treatments of two South African television advertisements and two newspaper advertisements depicting Western festive season symbols and rituals. The study revealed a broadly positive sentiment towards the festive season, where festive season activities allow participants to implement their Afrocentric cultural values of unity and collective responsibility. Findings also show that Afrocentric cultural values do affect the decoding of these marketing messages. There was also a variety of responses to marketing messages displaying the symbols of Christmas trees and Santa Claus, which were not common in BOP consumer households. The key recommendation highlighted by this study is that marketing messages communicated to South African BOP consumers should also consider Afrocentric values of unity and collective responsibility.  相似文献
