The legislator, in the German Federal Republic, has opted for a specific legal solution in relation to the protection of the embryo. Carola Müller, in this article, describes this regulation as well as the reasons that have led to its adoption. The article finishes with an exposition of the existing social discussion in German society and the effect that the law has had.  相似文献

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might reap the environmental benefits of international agricultural trade.  相似文献

This article reports the results of a study of the antecedents of long-term success in community mediation. Seventy-three mediation sessions were recorded and content analyzed. The participants were interviewed at two points: immediately after mediation and 4 to 8 months later. No relationship was found between the quality of the agreements—i.e., the extent to which they solved immediate problems- and long-term success as measured by compliance, improved relations between the parties, and the absence of new problems. On the other hand, joint problem solving by the disputants was related to complainant perceptions of improved relations with the other party. Also respondent perceptions that the mediation had been fair and that all the problems had come out were related to all aspects of long-term success in the eyes of the complainant. The latter results support a procedural justice analysis of mediation and underline the importance of mediator attention to the respondent.  相似文献

The story of Al Capone's rise and fall as a Chicago gangster has always depended upon selective dissemination of federal agency records, particularly records of the Internal Revenue Service. Capone history, therefore, is state-sanctioned history. The IRS view of the Capone organization, and of the tax evasion conviction, cannot be easily challenged without access to the corpus of the IRS records. Unfortunately, these records remain sealed from public access, despite the fact that selective releases were made prior to 1977 to journalists, popular authors, film producers and historians. Continued secrecy over the Capone records perpetuates a state-sanctioned criminology of organized crime. Calder v. Internal Revenue Service 1 attempted without success to unlock the corpus of IRS-Capone records to investigate the state-sanctioned view.  相似文献

Despite the recent increase in public and professional interest in the problem of wife beating in Arab society, in Israel, and in the rest of the Arab world, there is a serious lack of empirical research on different dimensions of the problem in those societies. This paper presents the results of a survey conducted among a systematic random sample of 362 Arab husbands from Israel, in an attempt to examine the contribution of patriarchal ideology toward explaining their beliefs about wife beating. Although about 58% of the participants indicated that there is no excuse for a man to beat his wife, 15–62% still justified wife beating on certain occasions (e.g., adultery, failure to obey husbands, disrespect for parents and relatives). In addition, although the participants tended to perceive abusive and violent husbands as responsible for their behavior, 52% still expressed understanding of that behavior and, on some occasions, 23–43% even blamed the wife for violence against her. Regression and multiple regression analyses revealed that over and above the participants' age and level of education, their masculine sex-role stereotypes, negative and traditional attitudes toward women, nonegalitarian marital role expectations, and familial patriarchal beliefs were the most significant predictors of beliefs about wife beating. Implications of the results and limitations of the study are also discussed.  相似文献
