Isoenzyme band patterns of animal blood erythrocyte acid phosphatase (EAP) and phosphoglucomutase-1 (PGM) were studied by isoelectric focusing on ultrathin polyacrylamide gels. For blood from all animals tested (dog, cat, cow, sheep, and goat), the overall band patterns for both isoenzymes were different from those of the most common human types of these enzymes, although some animal EAP and PGM bands appeared in the human band areas. When mixtures of human and animal red blood cells were studied, it was found that misinterpretation of human types was possible only if the overall band pattern of the mixtures was ignored. For the animal blood tested, the strong PGM bands appearing outside the human band areas could be used as "markers" for the possible presence of animal blood in the samples tested.  相似文献

This brief opposes the overturn of "Roe v. Wade" and resists weakening "Roe's central holding" that would allow states to overturn legal abortion. The brief was written for 885 law professors. "Roe" was not a "constitutional aberration," or "an exercise of raw, judicial power." Some members of the Supreme Court seem to think that the state has "an overriding interest" in protecting fetal life. Some Court members have questioned "Roe's" trimester framework. A person's decision to abort should be done privately. If women are not free to choose abortion, they will not have equality. There is an absence of "express rights of privacy and procreational freedom" in the Constitution. "Roe" was 1 instance of the Court's recognition of constitutional rights that are not named explicitly. Historical materials are drawn on to show the link between trends in society and the "judicial recognition of unenumerated rights." The most serious questions about "Roe" deal with its trimester framework. Justice Blackmun's majority opinion said that the 1st trimester of pregnancy was personal. "Roe" said that abortions created a medical risk at the beginning of the 2nd trimester. Therefore, the government was more interested in the health of the mother at that time. The state could then regulate abortion "in ways that are reasonable related to maternal health." The start of the 3rd trimester was when the fetus was viable. The right of a woman to end her pregnancy "offends powerful moral forces." Some of "Roe's" critics had their scientific facts wrong. Medical authorities think Justice O'Connor is mistaken when she says that "Roe" is "on a collision course with itself." The 23rd to 24th week of pregnancies where the fetal organs can "sustain life outside the womb." This has not changed since "Roe" was decided in 1973, nor is it likely to in the future. Some "amici" believe that the state can never have an interest in the fetus. The state can not have an interest in the fetus distinct from the woman who will give birth to it. During previability, restricting a woman's procreational rights would not be scientifically supportable. The state does have an interest in "upholding the value of human life." "Roe" is "within the mainstream" of constitutional jurisprudence and should be reaffirmed.  相似文献

Empathy is defined as an affect more appropriate to another's situation than to one's own. The paper (i) summarizes different modes of empathic affect arousal; (ii) shows how empathic affect may interact with social-cognitive development, to produce four levels of empathy development; (iii) suggests that causal attributions may transform empathic affect into sympathy, guilt, and empathic anger, which are major moral affects; (iv) discusses how these affects may influence moral judgment and behavior; (v) points up empathic morality's limitations and the need to embed empathy in relevant moral principles; (vi) discusses possible links between empathy and justice principles, with special focus on Rawls; (vii) illustrates the interplay of empathy, moral judgment, and justice; and (viii) suggests that moral principles may become hot cognitions.  相似文献

The computer-mediated network is a moderately expanding phenomenon. A major reason for this growth is the need for transferring technology to developing nations. But because many of these nations are not traditional users of advanced technology and because even the purveyors are not yet fully comfortable with the networks, the medium is not being used as much as perhaps it ought to be. In establishing a multinational network, one should be careful to treat all potential users with equity and not create an informational elite. Part of the challenge of such a system is making it accessible to operatives in the field. An effective way of introducing a network is to blend it with existing technologies, keep the costs down and the quality of information up, provide a usable information-retrieval system, and pay attention to microand macro-ergonomics. The Adult Education Network (AEDNET) of the Kellogg Project at Syracuse University has started working on a next-generation computer-mediated network system. It is proposed that AEDNET involve three action groups in the project: researchers, those interested in social implications, and users.  相似文献

"In this essay, certain aspects related to rural-urban mortality differentials in Mexico are analyzed....[These include] the availability, advantages, and limitations of different sources of information and the disparity of levels and tendencies according to particular indicators of acceptable reliability, especially those deriving from recent demographic surveys conducted in Mexico. The findings confirm an inverse ratio between size of settlement and mortality, and reveal a widening of the differentials over time." (SUMMARY IN ENG)  相似文献

The Federal Republic of Germany celebrated its fortieth anniversaryin May 1989. In spite of the devastation brought by World WarII, the division of the country between East and West, and theloss of one-fourth of its territory, the Bonn Republic was foundedunder more propitious circumstances than was its democraticpredecessa after World War I, the Weimar Republic. Togetherwith an "economic miracle" that brought about economic growthand a high standard of living. West Germany experienced a "politicalmirracle" that led to governmental stability and a system asdemocratic as any other in Europe. Federalism has contributedto this miracle, and, in contrast to the nineteenth century,is now identified closely with democracy in Germany. The articlescontained in this volume provide a broad overview of postwarfederalism in Germany, from its origins, organization, strengths,and weaknesses, to interpretations and assessments of currenttrends and developments.  相似文献

It is by now widely accepted that social science research has only an indirect and general impact on public policymaking. Academic social science research, it is often argued, is antithetical to policy research: the former is animated by traditional scientific canons while the latter is specific and problem-oriented. Moreover, modern bureaucracies are now understood as political environments within which pure research will be routinely ignored if it does not serve someone's interests. For these and other reasons, social scientists are being encouraged either to eschew policy research or not to expect much influence. This article provides an alternative model of social scientists in the policy process, as consulting critics reviewing, analyzing and commenting upon substantive policy research. This model holds benefits for both scholars and clients, turns the canons of scientific inquiry into assets instead of liabilities, and responds to some of the concerns recently raised in the literature concerning the role of social science in the policy process.  相似文献

A precise method for evaluating election schemes   总被引:1,自引:0,他引:1  
A previously published paper evaluated election schemes under a wide variety of election circumstances. This paper improves upon the previous work by refining the measures used to rate the election schemes and increasing the statistical significance of those ratings. With these modifications, we can now draw some new conclusions:
  1. In general circumstances, the Borda System outperforms the Copeland System which outperforms Approval which outperforms Majority Rule.
  2. The Maximin Rule — strongly supported by Rawls's — turns out to be a reasonable election rule if the number of election alternatives is large relative to the number of voters.
  3. With two exceptions, all our election systems performed quite well given a society with highly correlated utilities.
  4. Given a polarized society, a serial dictatorship was better than every other election system except Borda.
Perhaps even more importantly, we now have the possibility of conducting some cost/benefit analyses of different proposals for electoral changes.  相似文献
