SummaryThe effects of infant suckling patterns on the post-partum resumption of ovulation and on birth-spacing are investigated among the Gainj of highland New Guinea. Based on hormonal evidence, the median duration of lactational anovulation is 20·4 months, accounting for about 75% of the median interval between live birth and next successful conception. Throughout lactation, suckling episodes are short and frequent, the interval changing slowly over time, from 24 minutes in newborns to 80 minutes in 3-year olds. Maternal serum prolactin concentrations (...) decline in parallel with the changes in suckling patterns, approaching the level observed in non-nursing women by about 24 months post-partum. A path analysis indicates that the interval between suckling episodes is the principal determinant of maternal prolactin concentration, with time since parturition affecting prolactin secretion only in so far as it affects suckling frequency. The extremely prolonged contraceptive effect of breast-feeding in this population thus appears to be due to a slow decline in suckling frequency with time since parturition and absence of a decline over time in hypothalamic–pituitary responsiveness to the suckling stimulus.

SummaryThe Gainj of highland Papua New Guinea do not use contraception but have a total fertility rate of only 4·3 live births per woman, one of the lowest ever recorded in a natural fertility setting. From an analysis of cross-sectional demographic and endocrinological data, the causes of low reproductive output have been identified in women of this population as: late menarche and marriage, a long interval between marriage and first birth, a high probability of widowhood at later reproductive ages, low (...) effective fecundability and prolonged lactational amenorrhoea. These are combined with near-universal marriage, a low prevalence of primary sterility and a pattern of onset of secondary sterility similar to that found in other populations. Of all the factors limiting fertility, by far the most important are those involved in birth spacing, especially lactational amenorrhoea. (shrink)

The purpose of this research is to present the major factors that lead to ethical dissolution in an organization. Specifically, drawing from a wide spectrum of sources, this study explores the impact of organizational, individual, and contextual factors that converge to contribute to ethical dissolution. Acknowledging that ethical decisions are, in the final analysis, made by individuals, this study presents a model of ethical dissolution that gives insight into how a variety of elements coalesce to draw individuals into decisions that (...) result in the ethical undoing of an otherwise healthy organization. ENRON, TYCO and WorldCom did not happen in a vacuum. Nor can such debacles be explained as simply one or two individuals who were morally corrupt. The ethical breakdowns that occurred in these companies happened over a period of time, involved numerous individuals both inside and outside of the organization, and brought about the implosion of viable companies. Seeking to extend the work of previous researchers, this study attempts to tie together a disparate set of factors into a cohesive explanation of ethical breakdowns in organizations. (shrink)

Review of: Wood, Allen W., Kant and Religion, Cambridge, Cambridge U.P., 2020, 250 pp. ISBN: 978-0521799980.

The principal thesis in this review-essay is that the key linguistic terms in Fichte’s Wissenschaftslehre especially have two main meanings that appear at first sight to be almost in contradiction or opposed to each other. The reader of Fichte therefore has to work hard to overcome any apparent conflicts in the “double sense” of his philosophical terminology. Accordingly, I argue that Fichte’s linguistic method and use of language should be seen as part of his chief philosophical method of synthesis, where (...) we have to carry out a similar procedure and attempt to reconcile opposites using the power of the imagination. This thesis is put forward by means of a number of practical examples and in the context of some critical reflections on the recently published Cambridge Companion to Fichte, eds. David James and Günter Zöller. Review essay published in Volume 15 (December, 2017) of the journal Revista de Estud(i)os sobre Fichte (ed. Emiliano Acosta). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 535 second English volume), Ratzinger's Behold the Prerced One (pp. 1345 ), and W. Kasper's Theology and Church (pp. 94-108; Kasper says simply, "Rahner's characterization of neo-Chalcedonianism is historicaly inaccurate," p. 214, note 18). As it is, Ols's treatment reminds us that Rahner's own writings, which overlooked the later Councils of Constantinople, presume that Chalcedon had been the end of a development in Christology; this inaccurate presumption (...) has dominated too much of the writing which has followed Rahner's essay. Ols returns to this problem of " latent monophysitism " in some classical christologies in the final chapters of his work (VIII-XI). With a careful examination of the christology of Aquinas, the author skillfully demonstrates the rich development of Christ's true humanity that is possible within the classical approach; he deals specifically with the topics of Christ's knowledge, his sinlessness, and the concept of person. (It is interesting to note that, like Rahner and others before and after, Ols thinks that the word "person" is not particularly felicitous and would prefer simply the word hypostasis or subsistence [p. 187]. His wish is likely to have no more success than previous suggestions in this regard.) Although limited in its intent, this hook is rich in many ways. Ols's knowledge of St. Thomas is deep, and he uses that knowledge well. His critique of Rahner and Schilleheeckx may he forceful in its negative assertions, hut I believe it is accurate in pointing out the philosophical idealism that underlies much of their christological writings. This idealism is too often overlooked and needs the corrective of what we might call "Mediterranean realism." Although his criticism may he incisive, it is never unfair or strident, and he is aware of the positive insights that these men have contributed to our continuing reflections on the Lord. By intent, Ols's work is essentially one of evaluation and criticism. Nevertheless, the chapters that reflect on (and develop) Aquinas's teaching and give a positive presentation of the real human· ity of the Lord lead one to hope that the author will follow this study with a fully elaborated christology.

Several good hooks on Kant's political philosophy have appeared in the past decade, hut the literature on Kant's political philosophy is still both slimmer and weaker than on any other aspect of his thought. 536 BOOK REVIEWS Though we still await a definitive study of the topic, this book goes a long way toward filling some important gaps. Even the best books on Kant's political philosophy tend to treat only the broad outlines of Kant's position, shying away from detailed exposition of Kant's theories of individual right and external possession and of the political theory based on them. Mulholland's is not only the most detailed but also the most persuasive account of these matters which has yet been presented in English. The book's first four chapters attempt to lay the foundations for Kant's political philosophy through a general discussion of his ethical theory. The main function of these (somewhat overlong) introductory chapters is to argue for a tension between the law of nature formula (which Mulholland prefers as a guide to Kant's theory of right) and the formula of humanity as end in itself. According to Mulholland, the law of nature formula leads to a theory of rights and political obliga· tion which places Kant in the natural law tradition, whereas the formula of humanity commits him to what Mulholland calls the " deed principle ": that acquired rights can come about only through a deed on the part of those having the duties corresponding to the rights through which these duties have been assumed. Mulholland argues that if we take the deed principle strictly, then we must base political obligation on consent and thus on a social contract. The burden of Mulholland's argument throughout the book is that Kant cannot sustain the deed principle, and it is... (shrink)

While rooted in careful study of Mead’s original writings and transcribed lectures and the historical context in which that work was carried out, the papers in this volume have brought Mead’s work to bear on contemporary issues in metaphysics, epistemology, cognitive science, and social and political philosophy.

Since the publication of Edmund Gettier's challenge to the traditional epistemological doctrine of knowledge as justified true belief, Roberts and Wood claim that epistemologists lapsed into despondency and are currently open to novel approaches. One such approach is virtue epistemology, which can be divided into virtues as proper functions or epistemic character traits. The authors propose a notion of regulative epistemology, as opposed to a strict analytic epistemology, based on intellectual virtues that function not as rules or even as (...) skills but as habits of the heart. To that end, they divide the task of clarifying and expounding their notion in the book's two parts.In the first part, Roberts and Wood examine various components that constitute their notion of regulative epistemology. The first are the epistemic goods or goals that drive the epistemic process. What is needed, claim Roberts and Wood, is an enriched notion of these goods rather than the restricted notion of justified true belief. Epistemic agents are more than calculating devices in that ….

What do the rules of logic say about the meanings of the symbols they govern? In this book, James W. Garson examines the inferential behaviour of logical connectives, whose behaviour is defined by strict rules, and proves definitive results concerning exactly what those rules express about connective truth conditions. He explores the ways in which, depending on circumstances, a system of rules may provide no interpretation of a connective at all, or the interpretation we ordinarily expect for it, or (...) an unfamiliar or novel interpretation. He also shows how the novel interpretations thus generated may be used to help analyse philosophical problems such as vagueness and the open future. His book will be valuable for graduates and specialists in logic, philosophy of logic, and philosophy of language. (shrink)

This article analyzes astrobiology as a cosmopolitical project—the ways in which astrobiological “sensemaking” practices do philosophical, political, cultural, ontological, and ethical work as much as they do scientific work. More specifically, this article argues that astrobiology is engaged in the crafting of a new “origin myth” that makes sense of humanity’s place in the universe during our transition from the Holocene to the Anthropocene. In doing so, this article traces the ways in which astrobiology employs scientific methodologies and engages with (...) popular culture in ways that do four kinds of major work commonly found in origin myths: telling the origin story, demarcating the boundaries between self and the other, giving normative guidance, and declaring a shared societal purpose.

At present, Third World countries owe over one trillion dollars to the developed Western nations; much of the debt is held by the leading international commercial banks. The debt of six Latin American countries alone — Argentina, Brazil, Chile, Mexico, Peru, and Venezuela — is over $330 billion, of which $240 billion is owed to commercial banks. Let us immediately narrow our focus to loans made by the major international commercial banks to Third World governments. We shall not be concerned (...) with government-to-government loans, or private-party-to-private-party loans, or with debt owed to the World Bank or the International Monetary Fund. The bank-to-government loans — the so-called “sovereign loans” — are the most economically troublesome and morally interesting. The largest lenders, at least with respect to the Latin American countries, are the American banks Citibank, Chase Manhattan, Bank of America, Manufacturers Hanover, and Chemical Bank. About fifteen Third World countries have serious debt problems, including the largest: Brazil, Mexico, and Argentina. (shrink)

Kant was not a very knowledgeable historian of philosophy. He came to the study of philosophy from natural science, and later the fields of ethics, aesthetics, politics and religion came to occupy his central concerns, but his approach to philosophical issues never came by way of reflection on their history. He was well acquainted, of course, with the recent tradition of German philosophy: Leibniz, Wolff, Baumgarten and Crusius, and he seems also to have had knowledge of eighteenth century French philosophy, (...) and of as much of Anglophone philosophy as had been translated into either French or German. But like many modern philosophers, he had an inadequate appreciation of the scholastic tradition, and his knowledge of classical Greek philosophy was mostly at second hand. (shrink)

Profit is a concept that both causes and manifests deep conflict and division. It is not merely that people disagree over whether it is good or bad. The very meaning of the concept and its role in competing theories necessitates the deepest possible disagreement; people cannot agree on what profit is. Still, simply learning the starkly different sentiments expressed about profit gives us some feel for the depth of the conflict. Friends of capitalism have praised profit as central to the (...) achievement of prosperity and to civilized modern life. Calvin Coolidge, that silent sentinel of American business, said, “Profit and civilization go hand in hand.” F. A. Hayek tells us that in the evolution of the structure of human activities, profitability works as a signal that guides selection towards what makes man more fruitful; only what is more profitable will, as a rule, nourish more people, for it sacrifices less than it adds.

Behavior genetics is a controversial science. For decades, scholars have sought to understand the role of heredity in human behavior and life-course outcomes. Recently, technological advances and the rapid expansion of genomic databases have facilitated the discovery of genes associated with human phenotypes such as educational attainment and substance use disorders. To maximize the potential of this flourishing science, and to minimize potential harms, careful analysis of what it would mean for genes to be causes of human behavior is needed. (...) In this paper, we advance a framework for identifying instances of genetic causes, interpreting those causal relationships, and applying them to advance causal knowledge more generally in the social sciences. Central to thinking about genes as causes is counterfactual reasoning, the cornerstone of causal thinking in statistics, medicine, and philosophy. We argue that within-family genetic effects represent the product of a counterfactual comparison in the same way as average treatment effects (ATEs) from randomized controlled trials (RCTs). Both ATEs from RCTs and within-family genetic effects are shallow causes: They operate within intricate causal systems (non-unitary), produce heterogeneous effects across individuals (non-uniform), and are not mechanistically informative (non-explanatory). Despite these limitations, shallow causal knowledge can be used to improve understanding of the etiology of human behavior and to explore sources of heterogeneity and fade-out in treatment effects.

It is commonly asserted that “death is not a welfare issue” and this has been reflected in welfare legislation and policy in many countries. However, this creates a conflict for many who consider animal welfare to be an appropriate basis for decision-making in animal ethics but also consider that an animal’s death is ethically significant. To reconcile these viewpoints, this paper attempts to formulate an account of death as a welfare issue. Welfare issues are issues that refer to evaluations concerning (...) an animal’s interests. This includes evaluations that refer only to comparisons between the presence and absence of states, including positive states. This means that an animal’s death may be a welfare issue insofar as it leads to the exclusion of relevant positive states. This allows us to deny that death is necessarily not a welfare issue.

The United States has never been culturally or religiously homogeneous, but its diversity has greatly increased over the last century. Although the U.S. was first a multicultural nation through conquest and enslavement, its present diversity is due equally to immigration. In this paper I try to explain the difference it makes for one area of thought and policy – equal opportunity – if we incorporate cultural and religious pluralism into our national self-image. Formulating and implementing a policy of equal opportunity (...) is more difficult in diverse, pluralistic countries than it is in homogeneous ones. My focus is cultural and religious diversity in the United States, but my conclusions will apply to many other countries – including ones whose pluralism is found more in religion than in culture.

It is nearly 10 years since Patrick Haggard and colleagues first reported the ‘intentional binding’ effect . The intentional binding effect refers to the subjective compression of the temporal interval between a voluntary action and its external sensory consequence. Since the first report, considerable interest has been generated and a fascinating array of studies has accumulated. Much of the interest in intentional binding comes from the promise to shed light on human agency. In this review we survey studies on intentional (...) binding, focusing, in particular, on the link between intentional binding and the sense of agency . We suggest that, whilst it is yet to be fully explicated, the link between intentional binding and the sense of agency is compelling. We conclude by considering outstanding questions and future directions for research on intentional binding. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Dewey on Metaphysics, Meaning Making, and Maps James W. Garrison Blueprints and maps are propositions and they exemplify what it is to be propositional.1 [E]very characteristic trait is a quality.... produced and destroyed by existential conditions.2 John Dewey's claim that there are metaphysical generic traits of existence the theory of which provides "a ground-map" for cultural criticism remains controversial. I will work along two intertwining lines to try (...) and clear things up a bit. First, many assume that his reference to a metaphysical map is a metaphor. My paper will show that he uses the idea of a map consistently in many different places throughout his career. Second, my paper will examine how Dewey functionally coordinates ordinary existential traits and their maps within his theory of judgment. We will find that the generic traits and the ground-map of criticism connect in much the same way. Before examining Dewey's theory of judgment, I want to say something about where Dewey's metaphysics fits into his empirical "denotative method." In the conclusion, we wiU look at where metaphysics fits into the architectonic of his entire phUosophy. In between, we wiU examine maps functioning as propositions (especiaUy logical and mathematical universals) as weU as ever-evolving guides to unending inquiry in an unfinished and unfinishable universe. Eventually we wiU see why Dewey insists that "the social" is "The Inclusive PhUosophic Idea." Metaphysics, for Dewey, is simply one tool of cultural criticism among others.

PEIRCE SOCIETY Vol. 41, No. 4 ©2005 O situation from whence we may select traits, through the experience of "significant " linguistic meanings, such as the propositions of judgment, to the experience of "knowing" as the product of the logical process of inquiry, and back again to primary experience.4 Each phase interpenetrates every 3 other. Here is how Dewey describes the trans-action between primary, noncognitive and secondary, cognitive experience in his original (1925) >■$ introduction to Experience and Nature: ^r There are two avenues of approach to the goal of philosophy. We may " begin with experience in gross, experience in its primary and crude forms ^ [e.g., traits].... Or, we may begin with refined selective products, the a most authentic statements of commended methods of science [e.g., ¿q maps], and work from them back to the primary facts of life. ^ P TT ϕ > Philosophy may start with either immediate existential experience or the 3 experience of mediating meanings. While we may distinguish these two L starting points, we should never construct a dualism from them since both jx occur within experience.6 Dewey explains that "the subject-matter of primary experience sets the problems and furnishes the first data of reflection ""O which constructs the secondary objects of reflection."7 Further, "crude or macroscopic experience" provides the "test and verification" of the secondary objects of reflection. Secondary objects "explain the primary objects, 2 they enable us to grasp them with understanding!'9 The two starting points " differ in direction, but eventually they close to form a circle of expanding? dence.

A rationalist and realist model of scientific revolutions will be constructed by reference to two categories of criteria of theory-evaluation, denominated indicators of truth and of beauty. Whereas indicators of truth are formulateda priori and thus unite science in the pursuit of verisimilitude, aesthetic criteria are inductive constructs which lag behind the progression of theories in truthlikeness. Revolutions occur when the evaluative divergence between the two categories of criteria proves too wide to be recomposed or overlooked. This model of revolutions (...) depends upon a substantial new treatment of aesthetic criteria in science with which much of the paper will therefore be occupied. (shrink)

The aim of the study was to determine the acceptance and perception of Nigerian patients to medical photography. A self-administered questionnaire was distributed among Nigerian patients attending oral and maxillofacial surgery and plastic surgery clinics of 3 tertiary health institutions. Information requested included patients' opinion about consent process, capturing equipment, distribution and accessibility of medical photographs. The use of non-identifiable medical photographs was more acceptable than identifiable to respondents for all purposes (P = 0.003). Most respondents were favourably disposed to (...) photographs being taken for inclusion in the case note, but opposed to identifiable photographs being used for other purposes most especially in medical websites and medical journals. Female respondents preferred non-identifiable medical photographs to identifiable ones (P = 0.001). Most respondents (78%) indicated that their consent be sought for each of the outline needs for medical photography. Half of the respondents indicated that identifiable photographs may have a negative effect on their persons; and the most commonly mentioned effects were social stigmatization, bad publicity and emotional/psychological effects. Most of the respondents preferred the use of hospital-owned camera to personal camera/personal camera-phone for their medical photographs. Most respondents (67.8%) indicated that they would like to be informed about the use of their photographs on every occasion, and 74% indicated that they would like to be informed of the specific journal in which their medical photographs are to be published. In conclusion, non-identifiable rather than identifiable medical photography is acceptable to most patients in the studied Nigerian environment. The use of personal camera/personal camera-phone should be discouraged as its acceptance by respondents is very low. Judicious use of medical photography is therefore advocated to avoid breach of principle of privacy and confidentiality in medical practice. (shrink)

Thought experiment acquires evidential significance only on particular metaphysical assumptions. These include the thesis that science aims at uncovering "phenomena"universal and stable modes in which the world is articulatedand the thesis that phenomena are revealed imperfectly in actual occurrences. Only on these Platonically inspired assumptions does it make sense to bypass experience of actual occurrences and perform thought experiments. These assumptions are taken to hold in classical physics and other disciplines, but not in sciences that emphasize variety and contingency, such (...) as Aristotelian natural philosophy and some forms of historiography. This explains why thought experiments carry weight in the former but not the latter disciplines. (shrink)

We investigate the processes underlying the feeling of control over one’s actions . Sense of agency may depend on internal motoric signals, and general inferences about external events. We used priming to modulate the sense of agency for voluntary and involuntary movements, by modifying the content of conscious thought prior to moving. Trials began with the presentation of one of two supraliminal primes, which corresponded to the effect of a voluntary action participants subsequently made. The perceived interval between movement and (...) effect was used as an implicit measure of sense of agency. Primes modulated perceived intervals for both voluntary and involuntary movements, but the modulation was greatest for involuntary movements. A second experiment showed that this modulation depended on prime–movement contiguity. We propose that sense of agency is based on a combination of internal motoric signals and external sensory evidence about the source of actions and effects. (shrink)

Designed for use by philosophy students, this 2006 book provides an accessible, yet technically sound treatment of modal logic and its philosophical applications. Every effort has been made to simplify the presentation by using diagrams in place of more complex mathematical apparatus. These and other innovations provide philosophers with easy access to a rich variety of topics in modal logic, including a full coverage of quantified modal logic, non-rigid designators, definite descriptions, and the de-re de-dictio distinction. Discussion of philosophical issues (...) concerning the development of modal logic is woven into the text. The book uses natural deduction systems and also includes a diagram technique that extends the method of truth trees to modal logic. This feature provides a foundation for a novel method for showing completeness, one that is easy to extend to systems that include quantifiers. (shrink)

Michael Dummett and Storrs McCall have claimed that time travel scenarios in which an artist copies an artwork from a reproduction of it that has been sent from the future introduce a causal loop of a new kind: one involving artistic value. They have suggested that this poses a hitherto unacknowledged challenge to time travel theories. I argue that their conclusion depends on some unstated essentialist assumptions about metaphysics of art and the status of representations. By relaxing these assumptions, I (...) show that Dummett and McCall’s scenarios contain no causal loop involving artistic value, and thus pose no new problem for time travel theories. (shrink)
