This paper surveys three controversial new directions in research about the nature of science and briefly summarizes both the intellectual and sociological impact of this work. A bibliographic introduction to the major literature is provided and some fruitful directions for future research are proposed. Philosophers of science are also exhorted to perform 'community service' by correcting misunderstandings of the methods of science fostered by these new approaches.

Sudoku puzzles, which are popular worldwide, require individuals to infer the missing digits in a 9 9 array according to the general rule that every digit from 1 to 9 must occur once in each row, in each column, and in each of the 3-by-3 boxes in the array. We present a theory of how individuals solve these puzzles. It postulates that they rely solely on pure deductions, and that they spontaneously acquire various deductive tactics, which differ in their difficulty (...) depending on their “relational complexity”, i.e., the number of constraints on which they depend. A major strategic shift is necessary to acquire tactics for more difficult puzzles: solvers have to keep track of possible digits in a cell. We report three experiments corroborating this theory. We also discuss their implications for theories of reasoning that downplay the role of deduction in everyday reasoning. (shrink)

Aims: To describe individuals’ perceptions of the activities that take place within the cancer genetics clinic, the relationships between these activities and how these relationships are sustained. Design: Qualitative interview study. Participants: Forty individuals involved in carrying out cancer genetics research in either a clinical (n = 28) or research-only (n = 12) capacity in the UK. Findings: Interviewees perceive research and clinical practice in the subspecialty of cancer genetics as interdependent. The boundary between research and clinical practice is described (...) as vague or blurred, and this ambiguity is regarded as being sustained by a range of methodological, ethical and economic factors. The implications of these findings for the “therapeutic misconception” are explored. It is argued that while research participation is seen as having therapeutic benefit for individual patients, the interviewees are not labouring under any misconceptions about the relationship between research and clinical care. It is suggested that concepts such as the “therapeutic misconception” may have less relevance in highly technological specialities that are characterised by a developing evidence base. (shrink)

CHAPTER I Introduction The history of mankind can boast not only of its times of fame and glory but also of quieter times with a different kind of heroism. ...

Background: We were finding volunteers for functional magnetic resonance imaging studies with abnormalities requiring referral surprisingly frequently. The bioethics surrounding the incidental findings are not straightforward and every imaging institution will encounter this situation in their normal volunteers. Yet the implications for the individuals involved may be profound. Should all participants have review of their imaging by an expert and who should be informed? Methods: The normal volunteers that were imaged with magnetic resonance (MR) which were reviewed by a consultant (...) neuroradiologist. All participants completed a volunteer consent form in addition to a standard departmental MR safety screening form. The volunteer screening form requires the general practitioner details to be completed and asks the participant to consider closely the possibility and implications of finding an unexpected but potentially serious abnormality before signing. Results: 525 different individuals were scanned as normal volunteers, the mean age was 35-years and 330 were males. Of these 525, 46 had definite significant abnormalities (8.8%), mean age 50-years. Conclusion: We have found a high rate of incidental abnormalities amongst individuals participating in imaging studies at our institution. It is our current practice to inform the research study participant of the findings, counsel them and inform their primary care physician. We think that it is advisable for researchers utilising MR imaging of the brain to have access to trained neuroradiologists, a protocol in place to deal with this problem and take consent in a way that allows the participant to realise the possibility of an abnormal finding.

The relation of the special and the general principle of relativity to the principle of covariance, the principle of equivalence and Mach's principle, is discussed. In particular, the connection between Lorentz covariance and the special principle of relativity is illustrated by giving Lorentz covariant formulations of laws that violate the special principle of relativity: Ohm's law and what we call “Aristotle's first and second laws.” An “Aristotelian” universe in which all motion is relative to “absolute space” is considered. The first (...) law: a free particle is at rest. The second law: force is proportional to velocity. Ohm's law: the current density is proportional to the electrical field strength. Neither of these laws fulfills the principle of relativity. The examples illustrate, in the context of Lorentz covariance and special relativity, Kretschmann's critique of founding Einstein's general principle of relativity on the principle of general covariance. A modification of the principle of covariance is suggested, which may serve as a restricted criterium for a physical law to satisfy Einstein's general principle of relativity. Other objections that have been raised to the validity of Einstein's general principle of relativity are based upon the preferred state of inertial frames in the general, as well as in the special theory, the existence of tidal effects in “true” gravitational fields, doubts as to the validity of Mach's principle, whether electromagnetic phenomena obey the principle, and, finally, the anisotropy of the cosmic background radiation. These objections are reviewed and discussed. (shrink)

A negative image of community care prevails. This method of care is perceived to be a relatively novel phenomenon and has received mixed media coverage. The negative image of community care has led to the growing belief that this care method has failed. This failure has largely been ascribed to the lack of powers available to control patients in the community and to the method's relative novelty. However, this paper contends that there are two flaws to the above assertion: first, (...) community care is far from new, and second, the inherent problem is not the lack of powers available to control patients in the community, but, essentially, the absence of a secure and stable environment within the community.

In 1963 the American journalist Betty Friedan published her book The Feminine Mystique, in which she identified, on the basis of an analysis of women's magazines and surveys of women, a paradox in the self- awareness of American women: in striving to achieve the ideal of femininity, they devote themselves zealously to serving the family, and at the same time they feel they are "different" human beings from men, who have access to the world at large. Friedan compared the situation (...) of the housewife with the situation of a prisoner in a concentration camp. In both, a person is deprived of self-identity, of self-respect, and of manifesting one's individuality and is isolated from the large world of ideas and events. Friedan's general conclusion was that the ideal of "femininity" that guides women is not a natural bent of their natures but an inhumane stereotype that is imposed by advertising, business, and government because it is useful to society.

A model of dissipative quantum dynamics (with a nonlinear friction term) is applied to systems periodic in time. The model is compared with the standard approaches based on the Floquet theorem. It is shown that for weak frictions the asymptotic states of the dynamics we propose are the periodic steady states which are usually postulated to be the states relevant for the statistical mechanics of time-periodic systems. A solution to the problem of nonuniqueness of the “quasienergies” is proposed. The implication (...) of a nonlinear evolution for Ludwig's axiomatization is briefly outlined. (shrink)
