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)

Comments on: “Just War Theory in Comparative Perspective: AReview Essay” by Simeon O. Ilesanmi Journal of Religious Ethics 28.1 (Spring 2000).

The ethical principle of respect for autonomy has come into its own In American medicine since World War II as equal in importance to the traditional medicomoral principles of nonmaleficence and beneficence. Respect for autonomy provides the ethical underpinning for the patient's right to exercise an informed choice – whether to consent to or to refuse recommended medical treatment. However, an informed choice demands a certain level of competence. Typical criteria for patient competence to accept or to refuse medical treatments (...) Include ability to make a choice and ability to comprehend the nature of the treatment, as well as the risks and benefits of accepting or refusing the treatment. (shrink)

Now that mankind has created the capability of destroying itself through nuclear technology, is it still possible to think in terms of a "just war"? Johnson argues that it is, and in the context of specific case studies he offers moral guidelines for addressing such major contemporary problems as terrorist activity in a foreign country, an individual’s conscientious objection to military service, and an American defense policy that requires development of weapons that may be morally employed in case of (...) need. "Remarkable.... A thoughtful and even profound book, which can be warmly recommended."—Adam Roberts, _New Society_ __ "[A] wise, prudential, and moral thesis.... A most important book, one that all Americans who can should read."—George Armstrong Kelly, _Political Science Quarterly_ __ "At its heart, _Can Modern War be Just? _Is a challenge to the common assumption that any modern war must be total—an unrestrained, spasmodic release of one’s entire destructive capacity against the whole of the enemy’s population."—Richard Allen, _Journal of Religious Ethics_ __ "Johnson... seriously attempt[s] to balance principles and respect facts. For this he is to be praised."—Gary Jason, _Chronicles of Culture_ __ "Johnson’s application of just war doctrine to the hardest problems of contemporary warfare is both morally sensitive and intellectually bold. Readers will sometimes disagree with his arguments, but they will be forced to think hard, and they will learn what it is to work within a moral tradition."—Michael Walzer. (shrink)

The importance of history for religious ethics lies in the fact that, in religious communities existing over time, values are encountered in history, given forms dependent on the historical experience of the believing community, and recalled by the individual moral agent through memory in the context of participation in that community. This paper has to do with the nature of that memory and its implications for moral identity. Specifically, I utilize the concept of "significant history," derived from Gordon Kaufman's notion (...) of the "living past," arguing that moral identity is defined by memory of such history, present to the self in two aspects, individual and communal. The historical task of the religious ethicist, on this view, is to render faithfully both his own significant history and that of his community of faith. With the problem thus defined, I analyze several attempts to solve it, attempting to show how a religious ethical tradition ought to be treated as normative for contemporary analysis and decision-making.

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.

Christians have historically differed as to whether the wrongness of an act is to be located in the objective character of the act or in the intention of the agent. By blurring this distinction, Alain Epp Weaver fails to see the real principle of consistency that unites Augustine's analyses of warfare and lying. Likewise, by not appreciating the fact that Augustine analyzes the wrongness of the act in terms of intention whereas Yoder analyzes its wrongness in terms of its objective (...) character, Weaver proposes a conversation between two figures who lack the framework of shared assumptions that makes engagement in conversation possible.

Since World War II human rights language has come to occupy a central place in moral and legal discourse on the justification and limitation of armed conflict. At the core of contemporary international humanitarian law, concern for human rights has also developed as a vehicle for identifying and expressing moral concerns held in common across diverse cultural systems.

Since Einstein’s failure to define a Grand Unified Theory, physicists have pursued a comprehensive theory explaining nature, a Theory of Everything. But because General Relativity, Quantum Field Theory, and Cosmology have little in common, defining one theory is an imposing task, having eluded the best scientists for ninety years. So are we close to defining a Theory of Everything? This analysis, after defining requirements, identifies four possible options for a Theory of Everything. Quotes from prominent physicists express divergent views on (...) each alternative.The leading proposal for a Theory of Everything is String Theory, which has possible issues. It requires supersymmetry, has extra compacted dimensions, and is background-dependent. A second less comprehensive theory is Loop Quantum Gravity, which emphases background-independence based on discrete quantum space. Explaining how theories define relationships between spacetime, quantum space, quantum time, and quantum gravity, positions the role of background-independence in proposed theories. If supersymmetry and extra dimensions are discovered, String Theory or a modified String Theory integrated with Loop Quantum Gravity, may be the option. Or, possibly a radically new theory might be developed. Or, as the last option considers, the answer to the question — Does a Theory of Everything exist? — may be no; if so, nature will always be a mystery. (shrink)

This essay explores the idea of just war in two ways. Part I outlines the formation, early development, and substantive content of just war tradition in its classic form, sketches the subsequent development of this idea in the modern period, and examines three benchmarks in the recovery of just war thinking in American thought over the last four decades. Part II identifies and critiques several prominent themes in contemporary just war discourse, testing them against the context, purpose, and content of (...) the just war idea in its classic form. My argument throughout is that the historical substance of just war tradition needs to be respected in contemporary just war discourse, both to discipline that discourse and to engage contemporary moral reflection with the values embodied in just war tradition.

In spring 2020, COVID-19 and the ensuing social distancing and stay-at-home orders instigated abrupt changes to employment and educational infrastructure, leading to uncertainty, concern, and stress among United States college students. The media consumption patterns of this and other social groups across the globe were affected, with early evidence suggesting viewers were seeking both pandemic-themed media and reassuring, familiar content. A general increase in media consumption, and increased consumption of specific types of content, may have been due to media use (...) for coping strategies. This paper examines the relationship between the stress and anxiety of university students and their strategic use of media for coping during initial social distancing periods in March-April 2020 using data from a cross-sectional survey. We examine links between specific types of media use with psychological well-being concepts, and examine the moderating roles of traits (hope, optimism, and resilience) as buffers against negative relationships between stress and anxiety and psychological well-being. Our findings indicate that stress was linked to more hedonic and less eudaimonic media use, as well as more avoidant and escapist media-based coping. Anxiety, on the other hand, was linked to more media use in general, specifically more eudaimonic media use and a full range of media-based coping strategies. In turn, escapist media was linked to negative affect, while reframing media and eudaimonic media were linked to positive affect. Avoidant coping was tied to poorer mental health, and humor coping was tied to better mental health. Hedonic and need-satisfying media use were linked to more flourishing. Hope, optimism, and resilience were all predictive of media use, with the latter two traits moderating responses to stress and anxiety. The findings give a nuanced portrait of college students’ media use during a pandemic-induced shutdown, showing that media use is closely intertwined with well-being in both adaptive and maladaptive patterns.

Book reviewed in this article: Just War Tradition and the Restraint of War: A Moral and Historical Inquiry. By James Turner Johnson.

To assess the utility of appeals to natural law as a way of projecting ethical claims across ideological and cultural boundaries, three examples of such appeals in just war theory are critically analyzed and evaluated: those of contemporary international lawyers Myres McDougal and Florentino Feliciano, theological ethicist Paul Ramsey, and Franciscus de Victoria, a sixteenth-century Spanish theorist whose recasting of Christian just war thought gave rise to secular international law. The conclusion is that natural-law appeals today can no longer depend (...) on their own self-evidence, but must be attempts to uncover commonality as to what is natural. (shrink)

Multiverses are predictions based on theories. Focusing on each theory’s assumptions is key to evaluating a proposed multiverse. Although accepted theories of particle physics and cosmology contain non-intuitive features, multiverse theories entertain a host of “strange” assumptions classified as metaphysical topics such as: infinity, duplicate yous, hypothetical fields, more than three space dimensions, Hilbert space, advanced civilizations, and reality established by mathematical relationships. It is easy to confuse multiverse proposals because many divergent models exist. This overview defines the characteristics of (...) eleven popular multiverse proposals. The characteristics compared are: initial conditions, values of constants, laws of nature, number of space dimensions, number of universes, and fine tuning explanations. Future scientific experiments may validate selected assumptions; but until they do, proposals by philosophers may be as valid as theoretical scientific theories. (shrink)

The effectiveness of case-based learning in ethics education varies widely regarding how cases are presented. Case process instruction may impact case-based ethics education to promote sensemaking processes, ethical sensemaking strategy use, and ethical decision making (EDM) quality. This study examined two teaching techniques, notes and review, and participants completed note-taking and review activities examining a case-based scenario during an ethics education course. Results suggest that providing case notes in outline form improves sensemaking processes, strategy use, and EDM quality. In addition, (...) combining processes of provided notes and passive review results in incremental, additive performance via certain ethical sensemaking strategies and EDM quality. (shrink)

J. D. Monk has shown that for first order languages with finitely many variables there is no finite set of schema which axiomatizes the universally valid formulas. There are such finite sets of schema which axiomatize the formulas valid in all structures of some fixed finite size.
