Dialogue is tightly interwoven within everyday joint activities that require moment-by-moment coordination of utterances and actions. A common account of coordination is that it is established via progressive convergence (alignment, entrainment, similarity) of interlocutors' representations and behaviour. In order to examine how coordination is established and sustained, this paper distinguishes between (1) Semantic coordination of referring expressions (2) Procedural coordination of the timing and sequencing of contributions. Drawing on data from a series of maze experiments, this paper shows how both kinds of coordination result in the rapid development of highly elliptical, systematized and normative conventions. Focussing on how these conventions are established, this paper shows how interlocutors exploit partial repetition as an interactive resource, resulting in interlocutors' turns becoming progressively divergent and complementary. Further, this paper develops the claim that since repetition is best conceived as a special case of complementarity, it cannot be the general explanation of coordination. 相似文献

Technology pertaining to genetically modified foods has created an abundance of food and various methods to protect new products and enhance productivity. However, many scientists, economists, and humanitarians have been critical of the application of these discoveries. They are apprehensive about a profit‐driven mentality that, to them, seems to propel the innovators rather than a poverty‐elimination mentality that should be behind such innovations. The objectives should be to afford the most benefit to those in need and to prevent hunger around the world. Another major concern is the safety of genetically modified food. Muslims, as well as those in other religious communities, have been reactive rather than proactive. Muslims must connect scientific knowledge and ethical behavior based on faith. In Islam, there is no divide between the two. God has commanded us to seek knowledge and make discoveries to better our lives and our environment. We are trustees of this world and everything in it. The poor, the sick, and the wayfarers have a right to be fed and cared for. God reminds Muslims continuously that the earth and all the heavens belong to God; therefore, no one should feel hunger, no one should suffer or be prevented from sharing this bounty. 相似文献

Many Protestant denominations have or recently had policies that prohibit “self‐avowed practicing homosexuals” from being ordained. By only prohibiting “practicing” homosexuals, proponents of these policies claim that they do not discriminate against homosexuals as a group since, technically, a homosexual can still be ordained as long as she is “non‐practicing.” In other words, a condemnation of homosexual practice is not the same as a condemnation of homosexual persons. I argue that this is not the case; the rhetoric of homosexual practice does, in fact, amount to a condemnation of gays and lesbians. It does so by conflating the two things it claims to keep separate—homosexual conduct and homosexual identity. I demonstrate this conflation by analyzing the history of this rhetoric and how it has been adjudicated in church court decisions from the United Methodist Church and the Presbyterian Church (USA). 相似文献

Previously we showed that stress and depression could result in a 50% lowering of lymphocytic 5-ectonucleotidase (NT) which could be resolved by a diet high in antioxidants. This study suggested that high levels of free radicals mediated by stress/depression may be involved in lowering NT activities. The aim of the present study was to assess whether oxygen radicals could directly affect NT and whether excess free radicals generated in stress/depression may affect tissue ascorbate stores. Exam-stressed students and depressed patients were compared respectively to these students at low stress and depressed patients on high antioxidant intakes. In this study, NT correlated positively with tissue ascorbate stores. A range of antioxidants were tested as possible inhibitors of oxy radical interaction with NT using nitroblue tetrazolium reduction to for-mazan with superoxide anion. At physiological plasma concentrations, ascorbate inhibited this reduction but dehydroascorbate, tocopherol, retinol, selenium, urate, and reduced glutathione were ineffective. Superoxide anion directly reduced lymphocytic NT activity and this effect was reversed by either 100 molar ascorbate in vitro or a high antioxidant intake in vivo. In conclusion, the low NT activities and ascorbate stores found in stressed/depressed people appear to be mediated by higher levels of free radicals reported in these subjects. These conclusions are consistent with published reports of (1) normal NT levels in melancholic patients on high antioxidant diets; (2) heightened inflammatory reponses during stress/depression; (3) low serum levels of zinc in depressed patients. 相似文献

The basic (negative and positive) methodological maxims of three currents of philosophy of science (logical empiricism, falsificationism,
and postpositivism) are formulated. Many of these maxims (stratagems) are controversial, e.g., the stance about the nonsense
of metaphysics, and that of its indispensability. The restricted validity of these maxims allows for their unification. Within
the framework of most of them there may be a relationship of (synchronic, or diachronic) subordination of the contradicting
desiderata. In this vein ten stratagems are formulated.
