The method of approximate reasoning using a fuzzy logic introduced by Baldwin (1978 a,b,c), is used to model human reasoning in the resolution of two well known paradoxes. It is shown how classical propositional logic fails to resolve the paradoxes, how multiple valued logic partially succeeds and that a satisfactory resolution is obtained with fuzzy logic. The problem of precise representation of vague concepts is considered in the light of the results obtained.

Polyclonal antibodies raised against the human erythrocyte nucleoside transporter were used to investigate the distribution of the nucleoside transporters in the placenta. Immunoblots of brush-border membranes isolated from the human syncytiotrophoblast revealed a cross-reactive species that co-migrated with the erythrocyte nucleoside transporter as a broad band of apparent M(r) 55,000. In contrast, no labelling was detected in basal membranes containing a similar number of equilibrative nucleoside transporters as assessed by nitrobenzylthioinosine (NBMPR)-binding. The absence of cross-reactive epitopes in basal membranes and (...) their presence in brush-border membranes was confirmed by confocal immunofluorescence microscopy. The results suggest that at least two isoforms of the NBMPR-sensitive nucleoside transporter are present in the human placenta. The lumenal surfaces of fetal capillaries, small placental vessels and umbilical vein ware also strongly labelled by the antibody, a finding that suggests that the high fetal-placental adenosine uptake previously reported is due to endothelial transporters.

At the onset of the COVID-19 pandemic in the United States, stay-at-home orders disrupted normal research operations. Principal investigators (PIs) had to make decisions about conducting and staffing essential research under unprecedented, rapidly changing conditions. These decisions also had to be made amid other substantial work and life stressors, like pressures to be productive and staying healthy. Using survey methods, we asked PIs funded by the National Institutes of Health and the National Science Foundation (N = 930) to rate how (...) they prioritized different considerations, such as personal risks, risks to research personnel, and career consequences, when making decisions. They also reported how difficult they found these choices and associated symptoms of stress. Using a checklist, PIs indicated those factors in their research environments that made their decisions easier (i.e., facilitators) or more difficult (i.e., barriers) to make. Finally, PIs also indicated how satisfied they were with their decisions and management of research during the disruption. Descriptive statistics summarize PIs’ responses and inferential tests explore whether responses varied by academic rank or gender. PIs overall reported prioritizing the well-being and perspectives of research personnel, and they perceived more facilitators than barriers. Early-career faculty, however, rated concerns about their careers and productivity as higher priorities compared to their senior counterparts. Early-career faculty also perceived greater difficulty and stress, more barriers, fewer facilitators, and had less satisfaction with their decisions. Women rated several interpersonal concerns about their research personnel more highly than men and reported greater stress. The experience and perceptions of researchers during the COVID-19 pandemic can inform policies and practices when planning for future crises and recovering from the pandemic. (shrink)

Generalizedn-gons are certain geometric structures (incidence geometries) that generalize the concept of projective planes (the nontrivial generalized 3-gons are exactly the projective planes).In a simplified world, every generalizedn-gon of finite Morley rank would be an algebraic one, i.e., one of the three families described in [9] for example. To our horror, John Baldwin [2], using methods discovered by Hrushovski [7], constructed ℵ1-categorical projective planes which are not algebraic. The projective planes that Baldwin constructed fail to be algebraic in (...) a dramatic way.Indeed, every algebraic projective plane over an algebraically closed field is Desarguesian [12]. In particular, an algebraically closed field (isomorphic to the base field) can be interpreted in every one of them. However, in the projective planes that Baldwin constructed, one cannot even interpret an infinite group.In this article we show that the same phenomenon occurs for the generalizedn-gons ifn≥ 3 is an odd integer. For each suchnwe constructmany nonisomorphic generalizedn-gons of finite Morley rank that do not interpret an infinite group. As one may expect, our method is inspired by Hrushovski and Baldwin, and we follow Baldwin's line of approach. Quite often our proofs are a verification of the fact that the proofs of Baldwin [2] forn= 3 carry over to an arbitrary positive odd integern(which is sometimes far from being obvious). As in [2], we begin by defining a certain collection of finite graphsK* and a binary relation ≤ on these graphs. We show that (K*, ≤) satisfies the amalgamation property. (shrink)

According to familiar accounts, Rousseau held that humans are actuated by two distinct kinds of self love: amour de soi, a benign concern for one's self-preservation and well-being; and amour-propre, a malign concern to stand above other people, delighting in their despite. I argue that although amour-propre can (and often does) assume this malign form, this is not intrinsic to its character. The first and best rank among men that amour-propre directs us to claim for ourselves is that of occupying (...) 'man's estate'. This does not require, indeed it precludes, subjection of others. Amour-propre does not need suppression or circumscription if we are to live good lives; it rather requires direction to its proper end, not a delusive one. (shrink)

In the wake of a pilot study that indicated that the experience of medical education appears to Inhibit moral development In medical students, increased attention needs to be given to the structure of medical education and the Influence it has on medical students. Interest in ethics and moral reasoning has become widespread in many aspects of professional and public life. Society has exhibited great interest in the ethical issues confronting physicians today. Considerable effort has been undertaken to train medical students, (...) interns, and residents In how to reason through medical-ethical dilemmas. Media attention has focused on Issues such as abortion, euthanasia, care of severely handicapped infants, organ transplantation, and so forth, producing heated debates in both the professional and lay literature over the morality of the various positions. The curriculum of medical education has paralleled and reflected this general Interest in medical ethics. Most medical schools now offer, and frequently require, course work in ethics. However, further research Is needed to better characterize and understand the relationship of medical education to moral development. (shrink)

This note discusses critically a point in a d m walker's paper "the ideal of sincerity" ("mind", October 1978). Walker claims that desires are insincere if corrupted by incompatible desires. This view accounts for some cases, But not for all. It is argued, In the note, That superficial, Factitious, 'got up' desires are judged insincere as such because not 'natural' to a man. This is implied by the claim of andre gide's which walker misinterprets. The issue of natural desires in (...) contrast to artificial desires introduces the question of 'authenticity', Which is looked at in connection with lionel trilling's "sincerity and authenticity".

How do we refer to people in everyday conversation? No matter the language or culture, we must choose from a range of options: full name ('Robert Smith'), reduced name ('Bob'), description ('tall guy'), kin term ('my son') etc. Our choices reflect how we know that person in context, and allow us to take a particular perspective on them. This book brings together a team of leading linguists, sociologists and anthropologists to show that there is more to person reference than meets (...) the eye. Drawing on video-recorded, everyday interactions in nine languages, it examines the fascinating ways in which we exploit person reference for social and cultural purposes, and reveals the underlying principles of person reference across cultures from the Americas to Asia to the South Pacific. Combining rich ethnographic detail with cross-linguistic generalizations, it will be welcomed by researchers and graduate students interested in the relationship between language and culture.

The literature on affective determinants of physical activity is growing rapidly. The present paper aims to provide greater clarity regarding the definition and distinctions among the various affect-related constructs that have been examined in relation to PA. Affective constructs are organized according to the Affect and Health Behavior Framework, including: affective response to PA; incidental affect; affect processing; and affectively charged motivational states. After defining each category of affective construct, we provide examples of relevant research showing how each construct may (...) relate to PA behavior. We conclude each section with a discussion of future directions for research. (shrink)

Liberal critics of plato's republic criticise him for ignoring the moral autonomy of persons, their right to form and to express their own moral ideas. It is argued that this criticism is superficial. Neither plato, nor his liberal critics, wish all moral views to be held and acted on; they both wish to set limits to what is acceptable. The true source of disagreement is over the scope of reason in human affairs; plato understands that narrowly; his liberal critics in (...) a broad, permissive, way. (shrink)
