From 1956, when the complex ultrastructure of meiotic chromosomes was discovered, 1 until 1985, when the isolation of meiotic chromosome cores was reported, knowledge of the molecular structure of the meiotic chromosome was at best a dream. The dissection of meiotic chromosome structures has become a realistic challenge through the arrival of isolated symptonemal complexes (SCs), monoclonal and polyclonal antibodies against SCs, the possibility for screening expression libraries for genes that encode SC proteins, the isolation of SC‐associated DNA, and the (...) development of techniques for the in situ recognition of DNA sequences in the context of the meiotic chromosome structure.

Intuitionism has for many years been a poor relation among the various metaethical theories, commonly thought both parochial and irrational. Most recent writers who attempt a survey of ethical theory mention it briefly in an embarrassed sort of way, and then dismiss it in a paragraph or two. John Rawls, however, does not share this common attitude. In his recent book he represents his own theory as being an alternative both to intuitionism and to utilitarianism, and it is apparent from (...) his discussion that he takes both of these latter theories seriously, as having substantial attraction to reasonable men. Those sympathetic to intuitionism have no doubt been cheered by Rawls’ respectful treatment; but they are likely also to have been dismayed by the fact that, because he focuses upon a somewhat unusual understanding of it, he does not make clear how his theory stands in relation to intuitionism in its most general form, nor whether there are varieties of intuitionism consistent with the whole of his theory or at least with important parts of it. I shall try to answer these questions here. (shrink)

I argue that, If one adopts a minimal naturalism (of a kind rejected by moore, Hare, "et al".), One would adopt a methodology which yields conclusions identical to that yielded by intuitionistic methodology (of a kind employed by ross, Prichard, "et al".). I dilate upon the advantages which thus accrue to each theory, And I defend my minimal naturalism against a variety of objections.

In the recent spate of philosophers' writing on legal ethics, most contend that lawyers' professional role exposes them to great risk of moral wrongdoing; and some even conclude that the role's demands inevitably corrupt lawyers' characters. In assessing their arguments, I take up three questions: (1) whether philosophers' training and experience give them authority to scold lawyers; (2) whether anything substantive has emerged in the scolding that lawyers are morally bound to take to heart; and (3) whether lawyers ought to (...) defer to philosophers' claims about moral principle. I return a negative answer to each. (shrink)

In "moral arguments" ("mind", 1958), Philippa foot displayed what she claimed to be a deduction of an evaluative conclusion from a non-Evaluative premise. In "freedom and reason", R m hare attacks foot-Style deductions on two grounds: he first offers a "reductio", Comparing them to a racist deduction; he then offers an explanation of where all of these arguments go awry. I argue in my paper's first part that hare's explanation rests upon a defective criterion of entailment. In passing I show (...) how this counts against certain noncognitivist arguments that purport to show that moral judgments cannot be factual. In the second part I show that foot-Style deductions--And the racist deduction as well--Are either unsound or else superfluous to the naturalist's enterprise. From this I draw certain morals as to what conditions a successful naturalism must satisfy. (shrink)

IntroductionBisphenol A is highly debated and studied in relation to a variety of health outcomes. This large variation in the literature makes BPA a topic that is prone to selective use of literature, in order to underpin one’s own findings and opinion. Over time, selective use of literature, by means of citations, can lead to a skewed knowledge development and a biased scientific consensus. In this study, we assess which factors drive citation and whether this results in the overrepresentation of (...) harmful health effects of BPA.MethodsA citation network analysis was performed to test various determinants of citation. A systematic search identified all relevant publications on the human health effect of BPA. Data were extracted on potential determinants of selective citation, such as study outcome, study design, sample size, journal impact factor, authority of the author, self-citation, and funding source. We applied random effect logistic regression to assess whether these determinants influence the likelihood of citation.ResultsOne hundred sixty-nine publications on BPA were identified, with 12,432 potential citation pathways of which 808 citations occurred. The network consisted of 63 cross-sectional studies, 34 cohort studies, 29 case-control studies, 35 narrative reviews, and 8 systematic reviews. Positive studies have a 1.5 times greater chance of being cited compared to negative studies. Additionally, the authority of the author and self-citation are consistently found to be positively associated with the likelihood of being cited. Overall, the network seems to be highly influenced by two highly cited publications, whereas 60 out of 169 publications received no citations.ConclusionIn the literature on BPA, citation is mostly driven by positive study outcome and author-related factors, such as high authority within the network. Interpreting the impact of these factors and the big influence of a few highly cited publications, it can be questioned to which extent the knowledge development in human literature on BPA is actually evidence-based.
