Objective: This cross-sectional questionnaire-based study aims to compare physical activity and nature exposure levels between people living in France and Germany during the lockdown. Furthermore, the secondary aim is to observe the relationship between perceived stress, psychological health, physical activity, and nature exposure in Germany and France during the coronavirus disease 2019 -related lockdown of April/May 2020.Methods: The study includes 419 participants who have completed the Perceived Stress Scale 10, the World Health Organization Quality of Life-BREF, the Godin-Shephard Leisure-Time Physical (...) Activity Questionnaire, the modified Nature Exposure Scale, and complementary questions related to the lockdown period from April 19 to May 11, 2020. Multiple regression models were constructed to evaluate the relationship of nature exposure and physical exercise with overall stress perception and psychological health in France and Germany when considering a broad range of covariates.Results: Exposure to nature during the lockdown, amount of physical activity ηp2 = 0.014, p < 0.001), and psychological health were greater in German compared with French participants. Godin Index and Nature Exposure Scale total score were both inversely correlated to stress perception and positively correlated to psychological health. The stress and psychological health regression models explained 10% of the results' variance. Physical activity was a significant for both models. Nature Exposure Scale total score was a significant predictor only for psychological health. When including all significant covariates, the regression models explained 30.7% for the perceived stress and 42.1% for the psychological health total overall variance.Conclusion: Physical activity and nature exposure are significant predictors of psychological health. Even though both variables are associated with stress perception, only physical activity is a significant predictor of stress perception. Our results suggest that physical activity and nature exposure were key factors to go through the lockdown period in France and Germany. (shrink)

Schistosoma mansoni is one of several species of trematode helminths responsible for schistosomiasis, a major parasitic infection of man. Genetic analysis in mice has revealed that the protective immunity induced against this parasite by an attenuated larval vaccine is strongly influenced by genes regulating the activation of macrophage effector cells. The latter finding suggests that the induction of cell‐mediated immunity may be a successful strategy for a non‐living vaccine against the human infection.

Let κ denote a regular uncountable cardinal and NS the normal ideal of nonstationary subsets of κ. Our results concern the well-known open question whether NS fails to be κ + -saturated, i.e., are there κ + stationary subsets of κ with pairwise intersections nonstationary? Our first observation is: Theorem. NS is κ + -saturated iff for every normal ideal J on κ there is a stationary set $A \subseteq \kappa$ such that $J = NS \mid A = \{X \subseteq (...) \kappa:X \cap A \in NS\}$ . Turning our attention to large cardinals, we extend the usual (weak) Mahlo hierarchy to define "greatly Mahlo" cardinals and obtain the following: Theorem. If κ is greatly Mahlo then NS is not κ + -saturated. Theorem. If κ is ordinal Π 1 1 -indescribable (e.g., weakly compact), ethereal (e.g., subtle), or carries a κ-saturated ideal, then κ is greatly Mahlo. Moreover, there is a stationary set of greatly Mahlo cardinals below any ordinal Π 1 1 -indescribable cardinal. These methods apply to other normal ideals as well; e.g., the subtle ideal on an ineffable cardinal κ is not κ + -saturated. (shrink)

The relationship between religiosity and ethical behavior at work has remained elusive. In fact, inconsistent results in observed magnitudes and direction led Hood et al. (The psychology of religion: An empirical approach, 1996 ) to describe the relationship between religiosity and ethics as “something of a roller coaster ride.” Weaver and Agle (Acad Manage Rev 27(1):77–97, 2002 ) utilizing social structural versions of symbolic interactionism theory reasoned that we should not expect religion to affect ethical outcomes for all religious individuals; (...) rather, such a relationship likely depends on specific religious attitudes including religious motivation orientation (intrinsic RMO vs. extrinsic RMO), perceived sacred qualities of work (job sanctification), and views of God (VOG, loving vs. punishing). We examined the effects of these three religious attitudes on participants’ judgments of 29 ethically questionable vignettes. Consistent with symbolic interactionism theory, intrinsic RMO and having a loving view of God were both negatively related to endorsing ethically questionable vignettes, whereas extrinsic RMO was positively related to endorsing the vignettes. Unexpectedly, job sanctification was positively related to endorsing the vignettes. However, both intrinsic and extrinsic RMO moderated this relationship such that sanctifying one’s job was related to ethical judgments only for those who were: (a) low in intrinsic RMO or (b) high in extrinsic RMO. We reasoned based on symbolic interactionism theory that intrinsically motivated participants, in contrast to extrinsically motivated participants, may have utilized their religious beliefs as a guiding framework in making ethical judgments.

There have been repeated attempts in the history of comparative biology to provide a mechanistic account of morphological homology. However, it is well-established that homologues can develop from diverse sets of developmental causes, appearing not to share any core causal architecture that underwrites character identity. We address this challenge with a new conceptual model of Character Identity Mechanisms. ChIMs are cohesive mechanisms with a recognizable causal profile that allows them to be traced through evolution as homologues despite having a diverse (...) etiological organization. Our model hypothesizes that anatomical units at different levels of organization—cell types, tissues, and organs—have level-specific ChIMs with different conserved parts, activities, and organization. Relying on a methodology of conceptual engineering, we show how the ChIM concept advances our understanding of the developmental basis of morphological characters, while forging an important link between comparative and mechanistic biology.

These are the abstracts of papers for the conference, History Unveiled Science Unfettered: A Conference in Celebration of James E. McGuire University of Pittsburgh, January 19, 2002.

This book constitutes the refereed proceedings of the 10th International Conference on Inductive Logic Programming, ILP 2000, held in London, UK in July 2000 as past of CL 2000. The 15 revised full papers presented together with an invited paper were carefully reviewed and selected from 37 submissions. The papers address all current issues in inductive logic programming and inductive learning, from foundational aspects to applications in various fields like data mining, knowledge discovery, and ILP system design.

Confirmation theory is intended to codify the evidential bearing of observations on hypotheses, characterizing relations of inductive “support” and “counter­support” in full generality. The central task is to understand what it means to say that datum E confirms or supports a hypothesis H when E does not logically entail H.

Evidence that confirms a scientific hypothesis is said to be ‘novel’ if it is not discovered until after the hypothesis isconstructed. The philosophical issues surrounding novel confirmation have been well summarized by Campbell and Vinci [1983]. They write that philosophers of science generally agree that when observational evidence supports a theory, the confirmation is much stronger when the evidence is ‘novel’... There are, nevertheless, reasons to be skeptical of this tradition... The notion of novel confirmation is beset with a theoretical (...) puzzle about how the degree of confirmation can change without any change in the evidence, hypothesis, or auxiliary assumptions... There have not yet appeared any obviously satisfactory solutions to these problems Much of the literature on novel confirmation relies on the Bayesian analysis of conditional probabilities. Let H represent a hypothesis, E an event that confirms the hypothesis, and B some relevant background information. Denote by Pr the conditional probability of x given y. There are various plausible measures of the degree of support that E lends to H. Among these are: Degree of support = Pr Degree of support = Pr – Pr Degree of support = Pr – Pr Degree of support = Pr – Pt In the work cited, Campbell and Vinci offer a somewhat more involved Bayesian interpretation. Formula is discussed by Gardner [1981] who points out that under this formulation there can be no role for novelty. 'The function Pr contains no third slot in which to insert a temporal relation between the invention of H and the inventor's learning E. Obviously, then, this relation could not possibly affect E's support of H.' Formula, on the other hand, suggests a role for novelty. Bayes's Theorem allows us to rewrite the formula as Degree of support = Pr x [Pr – 1] We can use 1/Pr as a measure of the novelty of E. Then shows that the degree of support increases with novelty of E. In the paper already cited, Campbell and Vinci discuss shortcomings of this analysis. Formula expresses an alternative offered by Howson [1984]. In that formula, Pr represents the probability of H assuming that only B – {E} is known. This allows for the possibility of non-novel facts generating support for hypotheses. Niiniluoto [1984] argues for a variant along the lines of, in which we account for the possibility that the theorist was unaware that his hypothesis entails E. One problem in deciding among these approaches is that the choice of a definition for the degree of support appears arbitrary. What kind of argument could justify the choice of one definition over another? It is our position that there can be no basis for addressing this question in the absence of an explicit model of the process by which hypotheses are generated. Only in the presence of such a model can the various conditional probabilities be given meaningful interpretations. We provide such models in Sections 1, 2 and 4. The simple model of Section 1, incorporating strong assumptions, yields the conclusion that novelty is irrelevant. When these assumptions are relaxed in the later sections, novelty becomes relevant for a variety of reasons. It is at least potentially the case that scientists have more information about their own abilities than is publicly available, and this information might influence their decisions about whether even to attempt novel prediction. If this is so, then it should be incorporated into the model of hypothesis generation. This requires an explicit discussion of how scientists respond to incentives and how the incentives themselves evolve, which in turn takes us into the realm of economic theory. We have addressed these issues in another paper, written for an audience of economists. The results of this research are summarized in Section 3. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rethinking Utopia and Utopianism by Lyman Tower SargentWilliam James MetcalfLyman Tower Sargent. Rethinking Utopia and Utopianism. Ralahine Utopian Studies 26. Oxford: Peter Lang, 2022. 412 pp. Softcover, US$61, £53, €40. ISBN 978-1-80079-489-4.In the field of utopian studies, Lyman Tower Sargent is well known and respected globally. His new book, Rethinking Utopia and Utopianism, is well written, witty, and persuasively argued, reflecting on, and updating, his life’s [End (...) Page 137] work. It includes several previously published pieces, such as Sargent’s oft-cited “The Three Faces of Utopianism Revisited” (1994), along with his current thinking across the broad field of utopian studies.Sargent admits to naiveté when, as a young scholar in the 1960s, he set out to write a “history of utopian literature”—probably thinking it wouldn’t take long! This field, he soon found, ever expands the more one looks. Sargent continues to look for, and discover, examples from around the world—many of which he has made available online in Utopian Literature in English: An Annotated Bibliography from 1516 to the Present.1 But now, at eighty-two years of age, he accepts that this project will require “quite a few lifetimes, lifetimes that are not available to me, so I hope that others will take up these topics” (349).Sargent thinks utopianism is best understood as “social dreaming—the dreams and nightmares that concern the ways in which groups of people arrange their lives and which usually involve a radically different society” (7). Utopia, he points out, “expresses deep-seated needs, desires and hopes” (42). This, he asserts, is a universal phenomenon—part of being human—certainly not confined to the Western Christian tradition, as some scholars have argued.We must be careful, Sargent warns, not to equate utopia with perfection; utopias are about betterment, not perfection. He argues that equating utopia with perfection is a ruse employed “by those opposed to the idea that human beings can bring about significant social change and is intended to undermine that possibility” (323). Sargent argues that all humans “need the idea that a better life is possible” (325) and this is what utopianism provides.As someone who has spent much of my professional life studying intentional communities, I have always recognized that almost all such groups have an underlying utopian impulse. So I came to utopianism research as a subset of intentional communities research. Sargent, on the other hand, sees “communitarianism as a sub-category of utopianism” (85). He acknowledges that intentional community members are “trying to find better ways of living together, making decisions about all important aspects of life, whether it is political, economic, religious, or sexual.... They are actually doing with their own lives what literary utopias describe in words” (93). Perhaps our different paths are a bit like asking whether the chicken or egg came first?Sargent quite correctly observes that many intentional community members reject the label of “utopian” because they confuse it with the naïve, and unobtainable notion of perfection—and I have often observed the same. Nevertheless Sargent asserts “that continued utopian thinking is essential to the overcoming of [End Page 138] the dystopian reality of... the last century” (178). This, he argues, is why intentional communities are important test sites for enacting utopian dreams.In discussing dystopia, Sargent points out how utopian aspirations occasionally lead to the creation of dystopias. “The hopes of communism became the dystopia of Stalinism.... The utopian dreams of Pol Pot became the dystopia of Kampuchea” (172). “Utopian visions from Lenin to the Taliban that purported to have the potential of producing an enhanced life have been hijacked and turned into dystopias” (175). While acknowledging that some colonization schemes, particularly for New Zealand and South Australia, had a utopian angle, nevertheless those schemes generally created dystopia for the Indigenous peoples. “The original inhabitants’” idea of the good life “inconveniently did not include having their land stolen, being enslaved, and being slaughtered” (262).That reminds us that utopianism, like beauty, lies in the eye of the beholder. Sargent offers a wonderful personal example, “my utopia would include a strong right to die” whenever and however he... (shrink)

Given the pervasiveness of gene sharing in evolution and the extent of homology across the tree of life, why is everything not homologous with everything else? The continuity and overlapping genetic contributions to diverse traits across lineages seem to imply that no discrete determination of homology is possible. Although some argue that the widespread overlap in parts and processes should be acknowledged as “partial” homology, this threatens a broad base of presumed comparative morphological knowledge accepted by most biologists. Following a (...) long scientific tradition, we advocate a strategy of “theoretical articulation” that introduces further distinctions to existing concepts to produce increased contrastive resolution among the labels used to represent biological phenomena. We pursue this strategy by drawing on successful patterns of reasoning from serial homology at the level of gene sequences to generate an enriched characterization of serial homology as a hierarchical, phylogenetic concept. Specifically, we propose that the concept of serial homology should be applied primarily to repeated but developmentally individualized body parts, such as cell types, differentiated body segments, or epidermal appendages. For these characters, a phylogenetic history can be reconstructed, similar to families of paralogous genes, endowing the notion of serial homology with a hierarchical, phylogenetic interpretation. On this basis, we propose a five-fold theoretical classification that permits a more fine-grained mapping of diverse trait-types. This facilitates answering the question of why everything is not homologous with everything else, as well as how novelty is possible given that any new character possesses evolutionary precursors. We illustrate the fecundity of our account by reference to debates over insect wing serial homologs and vertebrate paired appendages. (shrink)

A central topic in research at the intersection of development and evolution is the origin of novel traits. Despite progress on understanding how developmental mechanisms underlie patterns of diversity in the history of life, the problem of novelty continues to challenge researchers. Here we argue that research on evolutionary novelty and the closely associated phenomenon of co-option can be reframed fruitfully by: (1) specifying a conceptual model of mechanisms that underwrite character identity, (2) providing a richer and more empirically precise (...) notion of co-option that goes beyond common appeals to “deep homology”, and (3) attending to the nature of experimental interventions that can determine whether and how the co-option of identity mechanisms can help to explain novel character origins. This reframing has the potential to channel future investigation to make substantive progress on the problem of evolutionary novelty. To illustrate this potential, we apply our reframing to two case studies: treehopper helmets and beetle horns. (shrink)

Although Ainslie dismisses the hot/cool framework as pertaining only to suppression, it actually also has interesting implications for resolve. Resolve focally involves access to our future selves. This access is a cool system function linked to episodic memory. Thus, factors negatively affecting the cool system, such as stress, are predicted to impact two seemingly unrelated capabilities: willpower and episodic memory.

Blair makes a strong case that fluid cognition and psychometric g are not identical constructs. However, he fails to mention the development of the prefrontal cortex, which likely makes the Gf–g distinction different in children than in adults.1 He also incorrectly states that current IQ tests do not measure Gf; we discuss several recent instruments that measure Gf quite well.

Nelson Goodman argues against those who, like Carnap, claim extensional identity is the criterion for correct constructional definition. Goodman argues that internal logical difficulties sink such a criterion, thus he proposes his own criterion of extensional isomorphism. We argue that Goodman's criterion itself falls prey to his own arguments or else extensional identity is not shown faulty.

This paper describes a new course in Medical Technology and Critical Decisions, part of the Technology Studies Program at Wellesley College, established with the support of the Alfred P. Sloan Foundation's New Liberal Arts Program. The course uses the dramatic new options in medicine presented by technology to individuals and society as a vehicle for promoting general technological literacy in liberal arts students. The course motivates the study of the scientific principles on which the technology rests and the mathematical principles (...) of a methodology for making rational choices. A case in point is the decision of a pregnant woman whether or not to undergo amniocentesis, a procedure used to determine the genetic make-up of a fetus from cells in the amniotic fluid. The course introduces students to the underlying notions of genetics; the physical principles behind the ultrasound imaging technique used to position the needle that draws the fluid; the probability and statistics needed to understand the risks to the woman and fetus both of having and of not having the procedure; and the methodology of decision analysis, increasingly used by genetic counselors to help prospective parents incorporate their personal values into the decision-making process.

What happens when an entire group of human beings is excluded from the definition of humanity? How is the power of language used to distort reality? What happens when a comprehensive economic plan is based on theft, brainwashing, slave labor, and murder? These and other philosophical questions about the Holocaust are contemplated in Contemporary Portraits of Auschwitz. In 1988, a group of philosophers who had survived the Holocaust, or had known people at the Auschwitz death camp, decided to found an (...) organization that would examine the philosophical implications of Shoah: the Society for the Philosophic Study of Genocide and the Holocaust. Noting that the history and the personal horror stories had been told and retold, SPSGH's founders Sander Lee, Berel Lang, and Alan Rosenberg argued that too little study had been so far devoted to the philosophy of Hitler's final solution and other genocides. Auschwitz problematized the Enlightenment concept of humanity, and other concepts. The perfection of state-sponsored and -administered mass death issued in new forms of language, moral indifference, and forgetting. Philosophy often even fails to mention the Holocaust in discussions of National Socialism. And the disaster of Auschwitz has been largely neutralized by the normalization of a "ruined" language.

Australia and Papua New Guinea share a number of important social, cultural, and historical features, making a sustained comparison between the two especially productive. This situates the ethnography of the two areas within a comparative framework and examines the relationship between indigenous systems of knowledge and place - an issue of growing concern to anthropologists. The essays demonstrate the manner in which regimes of restricted knowledge serve to protect and augment cultural property and the proprietorship over sites and territory; how (...) myths evolve to explain and culturally appropriate important events pertaining to contact between indigenous and Western societies; how graphic designs and other culturally important iconic and iconographic processes provide conduits of cross-cultural appropriation between indigenous and non-indigenous societies in today's multicultural nation states.

This introduction to contemporary social and political theory examines the impact of new ideas such as feminist theory, poststructuralism, hermeneutics and critical theory. The innovations brought by these intellectual traditions of Europe and America are outlined and discussed. Rather than focus on individual thinkers, the authors take a "conceptual" approach by examining contemporary theories through themes such as "critique", "rationality", "power", "the subject", "the body", and "culture". Each chapter considers the evolution of a concept and examines the major debates and (...) transformations that have taken place in that area. (shrink)

The respective roles of states and the federal government in health reform is a defining feature of any proposal. Heterogeneity among states implies the need for different approaches in different places, but a possible consequence is variation in results and outcomes around the nation.

Debates over health care reform often focus on the appropriate role for the government in health care. Much less attention is paid to defining the respective roles of the states and the federal government. Yet, in the American political system, the basic issue of federalism has profound implications.The question for the nation is which aspects of health policy should reflect national, uniform standards, and which should vary according to local conditions, values, and preferences. Economic mobility and the desire for efficiency (...) militate for national uniformity and federal standards. By contrast, state policies can be more closely tailored to local economic conditions and can reflect local values regarding matters such as the appropriate role of government. (shrink)
