During the summer of 2006, over four hundred Catholic ethicists from around the world gathered for four days in Padua, Italy. About sixty of the conference papers have become available in two edited collections, Catholic Theological Ethics in the World Church: The Plenary Papers from the First Cross‐cultural Conference on Catholic Theological Ethics, and Applied Ethics in a World Church: The Padua Conference. As the conference was marked by a distinctive and creative tension—between the diversity which characterized the nationalities and cultural identities of the participants, on the one hand, and the commonness of their religious heritage, on the other—these essays can tell us much about contemporary Catholic ethics in its response to global pluralism. The following develops four reflections. First, the conference papers pursue a style of scholarship that is at once critically creative and ecclesially rooted. Second, the conference raises new concerns about the importance that Christian formation must have in a pluralist world. Third, the participants affirm and defend the ultimate universality of moral goods while also arguing that these goods are expressed and embodied in unavoidably particular ways. Finally, the most important contribution that Catholic ethics can make to public conversations about issues of common concern is through its articulation and defense of key human values. 相似文献

Three theories of analogy have been proposed that are supported by computational models and data from experiments on human analogical abilities. In this article we show how these theories can be unified within a common metatheoretical framework that distinguishes among levels of informational, behavioral, and hardware constraints. This framework clarifies the distinctions among three computational models in the literature: the Analogical Constraint Mapping Engine (ACME), the Structure-Mapping Engine (SME), and the Incremental Analogy Machine (IAM). We then go on to develop a methodology for the comparative testing of these models. In two different manipulations of an analogical mapping task we compare the results of computational experiments with these models against the results of psychological experiments. In the first experiment we show that increasing the number of similar elements in two analogical domains decreases the response time taken to reach the correct mapping for an analogy problem. In the second psychological experiment we find that the order in which the elements of the two domains are presented has significant facilitative effects on the ease of analogical mapping. Of the three models, only IAM embodies behavioral constraints and predicts both of these results. Finally, the immediate implications of these results for analogy research are discussed, along with the wider implications the research has for cognitive science methodology. 相似文献

OBJECTIVE: Approximately 6,000 Americans die every year awaiting an organ transplant. Health promotion interventions may alleviate the shortage of viable organs by increasing the number of registered organ donors. This study is the first to evaluate the differential effectiveness of various organ donor messages in naturalistic settings. DESIGN: A 4 (Appeal)x4 (Exemplar)x4 (Location) counterbalanced quasi-experimental design was implemented. MAIN OUTCOME MEASURE: The behavioral outcome measure was the number of individuals who registered to be organ donors at computer kiosks. RESULTS: A number of significant main effects and interactions emerged. Most notably, of the 4 different appeals (counterargument, emotional, motivating action, dissonance), counterargument was by far the most efficacious, especially in academic-type settings (library, university, community college); the emotional appeal was most successful in hospitals. CONCLUSIONS: The findings from this study have implications for both organ donor investigations and health campaign research in general. Statistical interactions highlight the importance of evaluating multiple exemplars in multiple locations for each type of appeal when conducting health campaign research. 相似文献
