A theory of justice for the basic structure of society may constrain though not directly govern colleges. The principle of "equal opportunity" commonly applied to jobs either does or does not apply to varsity opportunities. If it applies, it interdicts sex discrimination but, one fallacious argument notwithstanding, it states no obligation to expend resources on new teams. If it does not apply, an analogue of Rawls's difference principle may appropriately constrain inequalities between the sexes. In either case the preferences of a majority of the sex affected by any inequality are pivotal in fashioning any tenable distributive policy. Those preferences are neglected by a government policy that assimilates equal opportunity to equality of (i) the ratio of male:female varsity athletes and (ii) the ratio of male:female students. It is argued that such policy rests on affirming the consequent. Its effects include misallocations of resources and overvaluation of athletics. It is argued that what should approximately be equal is competitive access, the ratio of available positions to aspirants, for each sex. Two versions of a principle of equal competitive access are proposed, the recommended one of which pertains to teams whose net consumption of resources is positive.  相似文献

Theoretical interest in Perelman's thought is linked, for the main part, to the place he accords to the notion of argumentation, defined in his work in reference to the Greek philosophy, as represented by Plato and Aristotle, in contrast to the assertions of the sophists and rhetors. He separates the notion of demonstration and that of argumentation and supports his position on an analysis of the debates which were common in the sophistic and rhetoric period.It is in different ways that the notion of argumentation comes into the work of Perelman. By taking up again the analysis of justice with the aim of removing the various strata of meaning which had accumulated on it as a result of the reductions of Plato and the dialectical analyses of Aristotle, Perelman showed that the theory of argumentation transcends the domain of right in which it is rooted and ought not be abandoned to lawyers only. Thus, he follows a train of thought to which he accords a certain nobilty in the name of the new rhetoric. This manner of considering the relationship of the moderns to the Greeks leads him to set up the notion of argumentation in his own texts, where it demonstrates a logical retreat which enables him to work back from Aristotle to Plato and from him to the rhetors and sophists, whose discourse is defined on the level of the self-referential.The exemplary character of Perelman's work is on account of this rehabilitation of argumentation in the old rhetoric which will be examined here.A slightly different version of this essay was presented at the Third Intenational Philosophy Symposium on Justice, Athens, 22–27 May 1987.  相似文献

Analysis of discriminative control by social behavioral stimuli   总被引:2,自引:2,他引:0       下载免费PDF全文
Visual discriminative control of the behavior of one rat by the behavior of another was studied in a two-compartment chamber. Each rat's compartment had a food cup and two response keys arranged vertically next to the clear partition that separated the two rats. Illumination of the leader's key lights signaled a “search” period when a response by the leader on the unsignaled and randomly selected correct key for that trial illuminated the follower's keys. Then, a response by the follower on the corresponding key was reinforced, or a response on the incorrect key terminated the trial without reinforcement. Accuracy of following the leader increased to 85% within 15 sessions. Blocking the view of the leader reduced accuracy but not to chance levels. Apparent control by visual behavioral stimuli was also affected by auditory stimuli and a correction procedure. When white noise eliminated auditory cues, social learning was not acquired as fast nor as completely. A reductionistic position holds that behavioral stimuli are the same as nonsocial stimuli; however, that does not mean that they do not require any separate treatment. Behavioral stimuli are usually more variable than nonsocial stimuli, and further study is required to disentangle behavioral and nonsocial contributions to the stimulus control of social interactions.  相似文献

Fifteen overweight girls aged 5 to 11 yr were randomly assigned to one of two weight-reduction treatments: response-cost plus reinforcement, response-cost only, or a no-treatment control group. In the response-cost plus reinforcement group, parents contracted to facilitate their child's weight loss by carrying out reinforcement and stimulus control techniques, completing weekly charts and graphs, and encouraging their child to exercise. The response-cost only group parents did not contract to reinforce their child's performance. The response-cost program applied to both experimental groups was conducted in weekly meetings in which parents lost previously deposited sums of money. Twenty-five per cent was deducted for missing the weekly meeting, 25% for failing to fill out charts and graphs, and 50% if their child failed to meet her specified weekly weight-loss goal. At the end of the 12-week treatment period, both experimental groups had lost significantly more weight than the control group. After an eight-week, no-contact follow-up, some of the lost weight was regained. The response-cost plus reinforcement group was still significantly below the controls. The response-cost group just missed significance. A 31-week, no-contact follow-up failed to show a treatment effect, but did show a trend towards slower weight gain by the response-cost plus reinforcement group.  相似文献

This study investigated the effects of interruption and differential reinforcement on seizures in children. Seizures were conceptualized as the terminal link in a behavioral chain, resulting in a strategy aimed at identifying and modifying behaviors that reliably preceded the seizure climax. Seizure frequency was reduced in four of five subjects, whereas the frequency of preseizure behavior was reduced in only three subjects. Parents and school personnel were successfully used as change agents.  相似文献

AIDS and the responses and attitudes it evokes surpass the analytic abilities of standard bioethics. These responses and attitudes are explored in terms of literary and anthropological categories, such as dirt, disorder, pollution and ritual cleanliness. Implications for medical education are suggested.  相似文献

Five‐year‐old children were presented with a story in which one character made three origami stars and another made nine. Then the participants were asked to distribute small rewards to each character (“Three” or “Four” candies), and were told to use all the candies (“All” instruction), or that “You can leave some candies, if you don't want to use all the candies (‘Partial’ instruction).” In Study 1, almost all children distributed the candies equally (Four). Some participants (28.1%) refused the All instruction for Three, and then equally distributed the candies. They conducted equality allocations in three or all four of the conditions, giving a ratio for “Thorough Egalitarians” of 20–30%. Study 2 used looking‐time measures to assess participants’ judgment. Children looked longer at the amounts of production of two characters in condition Three than in condition Four. Allocation patterns were almost identical to Study 1, but the condition “Partial‐Three” results were not reproduced. The paper discusses the types of egalitarian behavior and the associated production and reward quantities observed.  相似文献

The Cross     
ABSTRACT

My aim is a philosophical understanding of sacrifice, and especially of the Christian conception of sacrifice. Initially distancing myself a little from the strictly ritual notion of sacrifice, I work with a concept of sacrifice as 1) a voluntary choice (2) to forgo or lose or give away (3) something costly, perhaps supremely costly, (4) as an expressive action, where (5) what is so expressed typically is or includes devotion or loyalty to something exalted. I consider three historical examples of political sacrifices, sacrifices made for a cause, and three literary examples of personal sacrifices, sacrifices made by one person for another. I note that in the Christian context it is very common for sacrifices either political or personal to be taken to be imitations of Jesus’ sacrifice as presented in the New Testament, and ask therefore how we are to understand that. My conclusion is that Jesus’ sacrifice can be seen as involving both a political and a personal aspect—but that in fact, it can only be made as intelligible as may be by understanding it, as the Letter to the Hebrews does, in ritual terms.  相似文献

腐败是危害社会公正、法治的不良现象。为考察中国文化中的人情对腐败意图的影响,通过两轮问卷向190名大学生进行调查,结果发现:(1)人情不是单一整体,而是包含情感、资源、规范三个维度的复杂构念;(2)人情中的资源维度显著正向影响腐败意图,并且这一过程不受道德认同的影响。研究结果说明,为建立一个清廉、和谐的社会,人情中的不良成分,如利用人情资源获得优先对待必须被避免。  相似文献
