In the current investigation, 2 participants with mental retardation displayed property destruction and stereotypy, and both responses involved the same materials (e.g., breaking and tapping plastic objects). Three experiments were conducted (a) to indirectly assess the functions of these two responses, (b) to determine their relation to one another, and (c) to develop a treatment to reduce the more serious behavior, property destruction. In Experiment 1, previously destroyed materials were either present or absent, and their presence reduced property destruction but not stereotypy. In Experiment 2, matched toys (ones that produced sensory stimulation similar to stereotypy) were either present or absent, or were replaced by unmatched toys (for 1 participant). Matched toys produced large reductions and unmatched toys produced small reductions in property destruction and stereotypy. In Experiment 3, attempts to pick up undestroyed objects were either blocked or not blocked while matched toys were continuously available. Response blocking reduced property destruction (and attempts), prevented stereotypy, and increased manipulation of matched toys. These results suggest that the two aberrant responses formed a chain (e.g., breaking and then tapping the object), which was maintained by the sensory consequences (e.g., auditory stimulation) of the terminal response, and that previously destroyed material or matched toys made the initial response (property destruction) unnecessary. 相似文献

Libertarianism vs. Marxism: Reflections on G. A. Cohen‘s Self-Ownership, Freedom and Equality 总被引:1,自引:0,他引:1
Jan Narveson 《The Journal of Ethics》1998,2(1):1-26
Self-Ownership, Freedom and Equality is G.A. Cohens attempt to rescue something of the socialist outlook on society from the challenge of libertarianism, which Cohen identifies with the work of Robert Nozick in his famous book, Anarchy, State, and Utopia. Sympathizing with the leading idea that a person must belong to himself, and thus be unavailable for forced redistribution of his efforts, Cohen is at pains to reconcile the two. This cannot be done – they are flatly contrary. Moreover, equality is a nonsense principle, calling for such things as equal distribution of natural resources. But resources, as goods, are not natural: all require work to utilize. The only thing exchanged on markets is services, and estimates of value received are relevantly made only by those party to the exchanges in question. Imposition from above on voluntary exchange can only be socially counterproductive. 相似文献

市场经济、道德权利与产权伦理 总被引:6,自引:0,他引:6
产权伦理是现代市场经济的一个根本性的精神基础,是建立有效的产权制度及其运行机制的重要条件;同时,它是人类道德体系的核心价值理念之一,是基于权利,义务与道德的内在逻辑构建起来的。产权伦理的研究具有重要的理论价值和现实意义,可以构成一门具有特殊的学科特质,研究方法和理论内容的伦理学学科。 相似文献

归纳推理心理效应的研究 总被引:10,自引:0,他引:10
归纳推理心理效应指的是归纳论断中各种因素对个体做出归纳结论时把握性(力度)大小的影响,根据影响因素的不同,主要可分为类别效应、属性效应和交互效应三种。文章认为,个体通常会采用分割-综合方式判断归纳力度大小,并且在归纳判断中形成的推理序列及由此造成的顺畅感直接影响着归纳力度的估计,作者还提出了对此模型的一种证明 相似文献

Qualia and Physicalism. It is assumed that the following three relations exhaust the possibilities for a physicalist account
of qualia: 1. determination, 2. identity, 3. realization. The first relation is immediately rejected because it does not exclude
property dualism. The second faces the problem that it is probably impossible to discriminate empirically between the identity
thesis and the epiphenomenalist position. The third cannot handle qualia adequately, for qualia are not functional properties
and the realization relation is only plausible as a relation between physical realizers and functional properties. Finally,
if one attempts to replace multiple realization by multiple identities it is shown that the notion of multiple property identities
is unintelligible. The upshot is that if these three relations exhaust the possibilities of a physicalist construal of qualia
then physicalism is wrong.

Combinatory logic is known to be related to substructural logics. Algebraic considerations of the latter, in particular, algebraic considerations of two distinct implications (, ), led to the introduction of dual combinators in Dunn & Meyer 1997. Dual combinators are "mirror images" of the usual combinators and as such do not constitute an interesting subject of investigation by themselves. However, when combined with the usual combinators (e.g., in order to recover associativity in a sequent calculus), the whole system exhibits new features. A dual combinatory system with weak equality typically lacks the Church-Rosser property, and in general it is inconsistent. In many subsystems terms "unexpectedly" turn out to be weakly equivalent. The paper is a preliminary attempt to investigate some of these issues, as well as, briefly compare function application in symmetric -calculus (cf. Barbanera & Berardi 1996) and dual combinatory logic. 相似文献

In this paper, we present three main results on orthologics. Firstly, we give a sufficient condition for an orthologic to have variable separation property and show that the orthomodular logic has this property. Secondly, we show that the class of modular orthologics has an infinite descending chain. Finally we show that there exists a continuum of orthologics. 相似文献

Intellectual property has historically been a self-contained policy at the international level. With the introduction of the
TRIPs Agreement in 1994 and developments since the conclusion of the TRIPs Agreement, the relationship between intellectual
property policy and other areas of public policy has become much more complex and interactive. This shift reflects the centrality
of intellectual property in the knowledge economy, the rapid development of enabling technologies, notably the Internet and
biotechnology, and the advent of the networked society. The consequences of this shift are manifold and herald the increased
sophistication and complexity that may be expected of intellectual property regimes in the knowledge economy.
An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights
and Patents,” held in Warsaw, Poland on 23–24 April, 2004. 相似文献

Key ethical issues arise in association with the conduct of stem cell research by research institutions in the United States.
These ethical issues, summarized in detail, receive no adequate translation into federal laws or regulations, also described
in this article. U.S. Federal policy takes a passive approach to these ethical issues, translating them simply into limitations
on taxpayer funding, and foregoes scientific and ethical leadership while protecting intellectual property interests through
a laissez faire approach to stem cell patents and licenses. Those patents and licenses, far from being scientifically and
ethically neutral in effect, virtually prohibit commercially sponsored research that could otherwise be a realistic alternative
to the federal funding gap. The lack of federal funding and related data-sharing principles, combined with the effect of U.S.
patent policy, the lack of key agency guidance, and the proliferation of divergent state laws arising from the lack of Federal
leadership, significantly impede ethical stem cell research in the United States, without coherently supporting any consensus
ethical vision. Research institutions must themselves implement steps, described in the article, to integrate addressing ethical
review with the many legal compliance issues U.S. federal and state laws create.
The opinions expressed in this article are the author’s own, and are not necessarily the opinions of others, including Children’s
Hospital Boston. Portions of earlier versions of this article were previously published by the American Bar Association and

This paper evaluates the economic assumptions of economic theory via an examination of the capitalist transformation of creditor–debtor relations in the 18th century. This transformation enabled masses of people to obtain credit without moral opprobrium or social subordination. Classical 18th century economics had the ethical concepts to appreciate these facts. Ironically, contemporary economic theory cannot. I trace this fault to its abstract representations of freedom, efficiency, and markets. The virtues of capitalism lie in the concrete social relations and social meanings through which capital and commodities are exchanged. Contrary to laissez faire capitalism, the conditions for sustaining these concrete capitalist formations require limits on freedom of contract and the scope of private property rights. 相似文献
