An important recent development in worldwide Anglicanism is the emergence over recent years of a project to articulate the principles of canon law common to the churches of the Anglican Communion. This project seeks to express the juridical character of Anglicanism from a global perspective, not only to underscore the many fundamental values that Anglicans share in terms of their polity, ministry, doctrine, liturgy, rites and property, going to the very roots of Anglican identity but, also, as a concrete resource for other churches in ecumenical dialogue with Anglicans. This article traces the development of the so-called ius commune project, describes the methodological challenges which it faces and, the process of producing a draft. It also seeks to compare the project with the juridical experiences of other international ecclesial communities and, briefly, to place the project in the context of the debate about the adoption of an Anglican Covenant, an initiative proposed by the Lambeth Commission in 2004.  相似文献

Abstract

Using human embryos in research remains a controversial issue, especially in Christian bioethics. Although the official Catholic stance rejects human embryonic stem cell research, Christian thinkers T. Peters, K. Lebacqz and G. Bennett support it. They endorse the 14-day Rule and argue that ex vivo embryos lack moral worth. I examine and challenge the 14-day Rule and location argument (in vivo/ex vivo). I develop a theory of holistic anthropology and intrinsic moral value for human embryos. I conclude that intrinsic moral value is not equal to full moral value, and therefore use of embryos in biomedical research is morally permissible.  相似文献

Abstract

We need to distinguish between different types of experience and different experiential realms when we address the topic of human nature. Special emphasis is put on the hermeneutical dimension of human knowledge. The different experiential realms, which may give rise to natural, cultural and social, psychological and spiritual experiences, are then in turn assessed with regard to in what respect, for what purpose, and to what extent they can be used in order to establish a comprehensive and interdisciplinary justified view of human nature that takes all dimensions of human experience sufficiently into account.  相似文献

In a recent report on focus group discussions of GMOs in Britain, Celia Deane Drummond et al. observed that public anxieties about emerging biotechnologies often reflect concerns that are ultimately theological in nature. Such concerns (whether in relation to biotechnology or other areas of technological development) may be easily dismissed as peripheral or irrelevant to the core secular issues of health, safety, environmental impacts, the politics of commercialization and research integrity. However, I shall argue that theological questions are actually integral to the ongoing development of technology and that there is a need for a public discourse that enables such questions to be articulated and debated.  相似文献

Automated reasoning about uncertain knowledge has many applications. One difficulty when developing such systems is the lack of a completely satisfactory integration of logic and probability. We address this problem directly. Expressive languages like higher-order logic are ideally suited for representing and reasoning about structured knowledge. Uncertain knowledge can be modeled by using graded probabilities rather than binary truth values. The main technical problem studied in this paper is the following: Given a set of sentences, each having some probability of being true, what probability should be ascribed to other (query) sentences? A natural wish-list, among others, is that the probability distribution (i) is consistent with the knowledge base, (ii) allows for a consistent inference procedure and in particular (iii) reduces to deductive logic in the limit of probabilities being 0 and 1, (iv) allows (Bayesian) inductive reasoning and (v) learning in the limit and in particular (vi) allows confirmation of universally quantified hypotheses/sentences. We translate this wish-list into technical requirements for a prior probability and show that probabilities satisfying all our criteria exist. We also give explicit constructions and several general characterizations of probabilities that satisfy some or all of the criteria and various (counter)examples. We also derive necessary and sufficient conditions for extending beliefs about finitely many sentences to suitable probabilities over all sentences, and in particular least dogmatic or least biased ones. We conclude with a brief outlook on how the developed theory might be used and approximated in autonomous reasoning agents. Our theory is a step towards a globally consistent and empirically satisfactory unification of probability and logic.  相似文献

ABSTRACT

The Informant Questionnaire on Cognitive Decline (IQCODE) is a formal informant report instrument, originally developed by Jorm and Jacomb (1989 Jorm, A. F. and Jacomb, P. A. 1989. The Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE): Socio-demographic correlates, reliability, validity and some norms. Psychological Medicine, 19(4): 10151022. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Psychological Medicine, 19(4), 1015). The goal of the present study was to evaluate the range of cognitive decline in which the IQCODE is most sensitive, using item response theory (IRT). Existing data (N = 740) from a sample of community-dwelling older adults was used for this purpose. A 2-parameter model estimating item difficulty and discrimination fit the data best. Additionally, the IQCODE provided the most psychometric information in the range of ?0.5 < θ < 1.5, with peak information obtained at approximately θ = 0.4. Based on individuals' latent score (θ) estimates, items on the IQCODE are adequate for use as a screening tool for dementia. Results of the item calibration may be useful for targeted assessment needs, such as the development of short forms.  相似文献

The study investigated Teachers' gender stereotypes in the Eastern Province of South Africa. Participants were 65 Junior Secondary school teachers (females= 40 and males = 25) who assembled together at a seminar organized by the Department of Education. They completed a ten-statement questionnaire on gender stereotypes that would apply to school boys and girls. Data were analysed by means for differences in proportions endorsing stereotypes in relation to school activities. Gender stereotypes were apparent in the pattern of activities endorsed for males and females.  相似文献

In the first part of this article the author explores the implications for justice of the wider range of parties holding moral standing that environmental ethics has recently disclosed. These implications concern the equitable treatment of future generations and nonhuman creatures, and are relevant both to policies, such as approaches to global warming, and procedures, which may need to be revised to give an equitable voice to unrepresented interests. Later the author considers some radical implications of regarding humanity as stewards of the planetary environment, a view defended in his recent book Creation, Evolution and Meaning. If all adult humans have this role, but many are prevented from discharging it by poverty and related constraints, then those who are thus disempowered need to be empowered to exercise this role. This requirement of equity would arise not from their moral patienthood but from what is involved in respecting them as moral agents. Some approaches to tackling global warming are considered in this connection.  相似文献

In most studies on avoidance learning, participants receive an aversive unconditioned stimulus after a warning signal is presented, unless the participant performs a particular response. Lovibond (2006) recently proposed a cognitive theory of avoidance learning, according to which avoidance behaviour is a function of both Pavlovian and instrumental conditioning. In line with this theory, we found that avoidance behaviour was based on an integration of acquired knowledge about, on the one hand, the relation between stimuli and, on the other hand, the relation between behaviour and stimuli.  相似文献

We often remember in groups, yet research on collaborative recall finds “collaborative inhibition”: Recalling with others has costs compared to recalling alone. In related paradigms, remembering with others introduces errors into recall. We compared costs and benefits of two collaboration procedures—turn taking and consensus. First, 135 individuals learned a word list and recalled it alone (Recall 1). Then, 45 participants in three-member groups took turns to recall, 45 participants in three-member groups reached a consensus, and 45 participants recalled alone but were analysed as three-member nominal groups (Recall 2). Finally, all participants recalled alone (Recall 3). Both turn-taking and consensus groups demonstrated the usual pattern of costs during collaboration and benefits after collaboration in terms of recall completeness. However, consensus groups, and not turn-taking groups, demonstrated clear benefits in terms of recall accuracy, both during and after collaboration. Consensus groups engaged in beneficial group source-monitoring processes. Our findings challenge assumptions about the negative consequences of social remembering.  相似文献
