In much of the developing world daughters receive lower education and other investments than do their brothers, and may even be so devalued as to suffer differential mortality. Daughter disadvantage may be due in part to social norms that prescribe that daughters move away from their natal family upon marriage, a practice known as virilocality. We evaluate the effects of virilocality on female disadvantage using data from the Indonesia Family Life Survey. We find little support for the hypothesis. There is (...) no evidence that the overall pattern of rough equality in the treatment of boys and girls in Indonesia masks differences according to post-marital residential practice. Virilocal groups do not have "missing daughters." Nor is there other evidence of son preference, such as in relatively low height-for-age or education for girls and women in virilocal areas. Explanations of daughter disadvantage as due to virilocality should be subject to further scrutiny and contextualization. (shrink)

Background: There is evidence that household point-of-use water treatment products can reduce the enormous burden of water-borne illness. Nevertheless, adoption among the global poor is very low, and little evidence exists on why. Methods: We gave 600 households in poor communities in Dhaka, Bangladesh randomly-ordered two-month free trials of four water treatment products: dilute liquid chlorine, sodium dichloroisocyanurate tablets, a combined flocculant-disinfectant powdered mixture, and a silver-coated ceramic siphon filter. Consumers also received education on the dangers of untreated drinking water. (...) We measured which products consumers used with self-reports, observation, and chlorine tests. We also measured drinking water's contamination with E. coli. Findings: Households reported highest usage of the filter, although no product had even 30% usage. E. coli concentrations in stored drinking water were generally lowest when households had Water Guard. Households that self-reported product usage had large reductions in E. coli concentrations with any product as compared to controls. Conclusion: Traditional arguments for the low adoption of POU products focus on affordability, consumers' lack of information about germs and the dangers of unsafe water, and specific products not meshing with a household's preferences. In this study we provided free trials, repeated informational messages explaining the dangers of untreated water, and a variety of product designs. The low usage of all products despite such efforts makes clear that important barriers exist beyond cost, information, and variation among these four product designs. Without a better understanding of the choices and aspirations of the target end-users, household-based water treatment is unlikely to reduce morbidity and mortality substantially in urban Bangladesh and similar populations. © 2011 Luoto et al.

ABSTRACT Many philosophers who wish to defend abortion, but who have become frustrated by the resistance of the personhood question to yield to any nonarbitrary solution welcomed Judith Thomson's ‘A defense of abortion.’Thomson argues that abortion is sometimes justifiable even if the foetus is a person. In this paper I argue that Thomson's argument is a defense of abortion, rather than merely extraction without death, only because of the current state of medical technology. Once the technology is in place to (...) extract foetuses while preserving their lives and to allow them to develop to full term outside the uterus, Thomson cannot defend the killing of the foetus. If she is right, however, a woman will still have the right to have a foetus extracted from her body. Finally, it is pointed out that the source of the problem with Thomson's argument is the major premise in most arguments for the permissibility of abortion: a woman's right to control her own body. If the defence of abortion is to entail a defence of the termination of the foetus, then this premise, understood as the right to remove an unwanted entity from one's body or the right to alter one's body as one wishes, simply will not do the trick.

I examine Heidegger's reflections on the Anaximander fragment, concentrating on the question of justice. In his commentary, Heidegger draws on Nietzsche's thoughts about justice, the will to power, and nihilism to formulate an interpretation of the fragment that connects it to the epochal history and destiny of being. This "ontological" interpretation, constructed in a compelling reading of the history of philosophy, requires that Heidegger first address the historicism and "ontological forgetfulness" prevailing in historical consciousness and historiography, in order to begin (...) thinking towards the possibility of another epoch of being, releasing us from the injustice that is inherent in the ontology that rules in the present historical dispensation. Although Heidegger avoids moral prescription, he cannot avoid critical entanglement in the moral-juridical sense of justice, despite his claims and protestations, since, as his own account of the fragment implies, justice and ontology must be inseparable. Reading Heidegger's commentary in relation to Benjamin's philosophy of history, I argue that Heidegger's reflections on justice suggest a narrative of tragic hope that resembles Benjamin's configuration of justice in his reading of the Baroque mourning-play, where the hopelessly fragmented and imperiled image of justice is revealed as emerging from a Leidensgeschichte fatefully bound up in the continuum of a Schuldgeschichte.

DNA joining enzymes play an essential role in the maintenance of genomic integrity and stability. Three mammalian genes encoding DNA ligases, LIG1, LIG3 and LIG4, have been identified. Since DNA ligase II appears to be derived from DNA ligase III by a proteolytic mechanism, the three LIG genes can account for the four biochemically distinct DNA ligase activities, DNA ligases I, II, III and IV, that have been purified from mammalian cell extracts. It is probable that the specific cellular roles (...) of these enzymes are determined by the proteins with which they interact. The specific involvement of DNA ligase I in DNA replication is mediated by the non‐catalytic amino‐terminal domain of this enzyme. Furthermore, DNA ligase I participates in DNA base excision repair as a component of a multiprotein complex. Two forms of DNA ligase III are produced by an alternative splicing mechanism. The ubiqitously expressed DNA ligase III‐α forms a complex with the DNA single‐strand break repair protein XRCC1. In contrast, DNA ligase III‐β, which does not interact with XRCC1, is only expressed in male meiotic germ cells, suggesting a role for this isoform in meiotic recombination. At present, there is very little information about the cellular functions of DNA ligase IV. (shrink)

In this study, I examine the significance of the trace and its legibility in the phenomenologies of Merleau-Ponty and Levinas, showing that this trope plays a more significant role in Merleau-Ponty's thinking than has been recognized heretofore and that it constitutes a crucial point of contact between Merleau-Ponty and Levinas. But this point of contact is also, in both their philosophies, a site where their thinking is compelled to confront its limits and the enigmas involved in the description of the (...) topography of a hermeneutical flesh. It is argued that the significance of the trace consists in its alterity, its registering and inscribing in the very matter of the flesh an imperative spiritual assignment: the morally binding hold of the other person on my capacity to be responsive to the other's needs and bear responsibility for the other's welfare. The retrieval or recuperation of the trace, which, I argue, is inscribed as a certain predisposition in what, borrowing from Merleau-Ponty, we might call the prepersonal topology of the flesh, would thus constitute a task of the utmost importance for the formation of the moral self. However, given the paradoxical temporality of the trace and the hermeneutical nature of its legibility, the retrieval of the trace is not actually possible. Nevertheless, the attempt to retrieve it - one's commitment to retrieving it - is an absolutely imperative existential task, determining the character of the moral self. In both Merleau-Ponty and Levinas, however, the problematic nature of this recuperative project is manifested in the ambiguous, equivocal modality of their rhetoric, supposedly engaged in the phenomenological description of the primordial 'inscription', but oscillating, in fact, undecidably between descriptive and prescriptive, constative and performative, literal and metaphorical modes of discourse. It is argued that this, far from being a fault, is necessitated by the hermeneutic nature of the trace, which requires that the description be invocative and evocative, provoking a deep transformation in experience that would make the description true. It accordingly becomes clear that and why the moral phenomenologies of Merleau-Ponty and Levinas, depending as they must on a metaphorical interaction between language and experience, cannot function within the framework of the traditional correspondence theory of truth.

In lieu of an abstract, here is a brief excerpt of the content:David Michael Levin ROUSSEAU'S CURSE Pretext Rousseau is the author of a text he called his Confessions. ' But neither a text nor a confession can exist without a reader, or an other. Like it or not, we readers are participants in the rite of Rousseau's confessions. Do we have anything to confess? When the reading of a confession uncovers the spelling of a curse, so that the (...) self-accused author appears to accuse his readers, the discoverers of the curse can no longer pretend their neutrality and innocence. In fact, the detectives must assume the identity of the accused. In such a special case, then, the inevitable work of textual interpretation magically doubles as the story of a mysteriously elusive "crime" and its final, or anyway presumed detection. But, as in the very best of such stories, neither the skillfully executed crime nor its invisible author—if indeed these terms denote anything at all—need be what they seem. So perhaps the only thing we can say for sure here is that the spelling of the curse is the curse of spelling. And this puts us on the track of a mystery as ancient as the art of writing itself—a mystery whose story the scholars of hermeneutics have thus far preferred to ignore. The mystery I have in mind is the secret affinity between writing and death. A careful hermeneutic approach to Plato's critique of writing, however, may give us a crucial clue. For what binds written language to the power of death is its role in mourning, its incarnation in the form of shadows: black configurations of shadows placed for visibility against the white of the paper. In Plato's Myth of the Cave, the crime of writing is dimly adumbrated. Writing is idolatry, worship of false images, shadows. Rousseau's Confessions, written near the end of his life in the shadow of death, does not escape the shadows of doubt and suspicion which we, his readers, having discovered our own selves inscribed into the darkness of the text, cannot easily refrain from casting. But as soon as we recognize in the shapes of these shadows a suspicion for which 76 David Michael Levin77 we are responsible, we must confess our fatal complicity in the closing of the hermeneutical circle. Commentary on the Text If Rousseau's Confessions does not read like the typical memoir, neither does it read like the typical confession. A final twist awaits us. We read with a certain innocence, or faith, not prepared for the transitive conclusion: the text, as it happens, will bequeath a monstrous and impossible burden. What is the reader to do? How could it be that this man, who seemed to honor us, and won our trust with the candor of his revelations, should so boldly, by one cross conceit, vanish, only to leave us double-crossed and within a labyrinth which, as he would have us believe, we ourselves have wrought? What are we to make of his work? At first, the Confessions appears to be a work of light: with dazzling clarity of mind and courage no less prismatic, Rousseau proposes to take his readers into the gloomy chasms of his soul. "My purpose," he declares, "is to display to my kind a portrait in every way true to nature, and the man I shall portray is myself" (p. 17). That this, however, is not the whole of his intention, we learn through a neighboring sentence. For he says: "Let the last trumpet sound when it will, I shall come forward with this work in my hand, to present myself before my Sovereign Judge, and proclaim aloud: 'Here is what I have done'..." (p. 17). And yet, even this does not fully disclose his design, since he concedes, somewhat later, that "it is as if, feeling my life escaping from me, I were trying to recapture it at its beginnings" (p. 31). But in the end, as in the beginning, darkness and light are one. And indeed, deep into the Seventh Book, we see that the author's light does begin to dim, and that he no longer speaks with much assurance. Nor is... (shrink)

In this paper I examine important texts by Jacques Derrida in which, either implicitly or explicitly, the Shoah, the catastrophe of the Holocaust is signified, interrupting, disrupting, even disfiguring the texture of the text. The question is how appropriately to remember and mourn the dead within philosophical discourse, how to remember what happened and how to understand it as a question not only of ethical and political responsibility but also as an evil deeply and pervasively reflected in the ontology and (...) epistemology of the philosophical tradition—an evil circulating within the very substance of philosophical thought, and in such a way that Derrida will make this philosophical complicity in the violence and evil of the Holocaust register its painfully oppressive guilt in textual configurations haunted by the presence of the victims, remembered in traces of their absence. Thus we see how Derrida lets the question of an appropriate form of historical memory, a fitting way to remember the Shoah, invade his texts—how he lets the texts of his thought be exposed to its radical evil and exposed to the pain of an impossible mourning. We also see how the deconstruction of the metaphysics of presence implies a contestation of historicism, a writing of history that betrays the past in the very process of making it present. (shrink)

In a recent paper, Shaun Nichols (2002) presents a theory that offers an explanation of the cognitive processes underlying moral judgment. His Affect-Backed Norms theory claims that (i) a set of normative rules coupled with (ii) an affective mechanism elicits a certain response pattern (which we will refer to as the “moral norm response pattern”) when subjects respond to transgressions of those norms. That response pattern differs from the way subjects respond to violations of norms that lack the affective backing (...) (here referred to as the “conventional norm response pattern”). In response, Daniel Kelly and colleagues (2007) present data that, the authors claim, undermine Nichols’ Affect-Backed Norms theory by showing that there are novel cases in which (i) and (ii) are in place, yet subjects respond in the way typical of the conventional response pattern. In Section I of this paper we summarize the challenge to the Affect-Backed Norms theory from the novel cases introduced by Kelly et al. We then show how the challenge is potentially flawed because no verification was provided that subjects were experiencing affect when reading the cases, nor was level of affect controlled for. In Section II, we describe the study we conducted to determine what level of affect was induced when subjects read the novel cases. In Section III, we present our findings, namely that subjects respond to the novel cases with different levels of affect, which tracks their judgments of the severity of the transgressions in the cases. In Section IV, we discuss the results and show that the Affect-Backed Norms theory can explain subjects’ responses to the novel cases given this new 2 information about affective response. In Section V, we conclude with a thought about how these findings inform the traditional moral/conventional distinction. (shrink)

Three questions govern this ``phenomenological'' inquiry: (1) how are sanity and madness spatialized? (2) how do myths shape lived space? (3) how can we moderns use primitive myth-systems to restructure lived space? i contrast newtonian and einsteinian spaces with the original space of our living. i show that this 'normal' space, and the spaces of science, are structured by the egological subject and therefore reflect ego-pathology. can we use myths to schematize a more satisfying space?

In this paper I discuss the claim (advanced in various ways by Joseph Levine, Frank Jackson and David Chalmers) that the successful reduction of qualitative to physical states requires some sort of intelligible connection between our qualitative and physical concepts, which in turn requires a conceptual analysis of our qualitative concepts in causal‐functional terms.

Philosophers and psychologists alike have argued recently that relatively abstract beliefs or cognitive categories like those regarding race can influence the perceptual experience of relatively low-level visual features like color or lightness. Some of the proposed best empirical evidence for this claim comes from a series of experiments in which White faces were consistently judged as lighter than equiluminant Black faces, even for racially ambiguous faces that were labeled ‘White’ as opposed to ‘Black’ (Levin and Banaji 2006). The latter result (...) is considered especially indicative of cognitive penetration, based on the reasoning that the relevant distortions were a function of lexical labeling, and hence the effect must have been mediated by categorization at the cognitive level. I argue that this reasoning is flawed, and that the assumptions on which it relies are questionable on both empirical and theoretical grounds. I propose an alternative, low-level explanation of the phenomena, which I argue is empirically more plausible and abductively preferable to the cognitive-penetration account. The upshot is that cognitively impenetrable perceptual systems may be psychologically more plastic and hence philosophically more significant than is nowadays commonly assumed. (shrink)

We discuss presupposition, the phenomenon whereby speakers mark linguistically the information that is presupposed or taken for granted, rather than being part of the main propositional content of a speech act. Expressions and constructions carrying presuppositions are called “presupposition triggers”, forming a large class including definites and factive verbs. The article first introduces the range of triggers, the basic properties of presuppositions such as projection and cancellability, and the diagnostic tests used to identify them. The reader is then introducedto major (...) models of presupposition from the last 50 years, separated into three classes: Frege-Strawson derived semantic models, pragmaticmodels such as that offered by Stalnaker, and dynamic models. Finallywe discuss some of the main current issues in presupposition theory. These involve accommodation, which occurs when a hearer's knowledge state is adjusted to meet the speaker's presuppositions; presupposition failure, which occurs when a presupposition is false; the interaction between presuppositions and attitudes; and the triggering problem, i.e., the problem of explaining why presuppositions occur in the first place.

The extremely high level of simulated violence in certain recent video games has made some people uneasy. There is a concern that something is wrong with these violent games, but, since the violence is virtual rather than real, it is difficult to specify the nature of the wrongness. Since there is no proven causal connection between video-game violence and real violence, philosophical analysis can be particularly helpful in locating potential sources of wrongness in ultra-violent video games. To this end, this (...) paper analyzes video game violence through the lens of utilitarian, Kantian, and post-modern perspectives. Through these analyses, several explanations of the wrongness in violent video games emerge. (shrink)

At the round table, the following problems were discussed: the specificity of consciousness problem, (...) its relevance in various academic disciplines, contemporary research possibilities for consciousness studies to solve the problems that specialists actually face. Much attention was paid to the problems of neurobiology, empirical research of consciousness. Nonetheless, participants showed in their speeches that the problem of consciousness is also a philosophical problem. Hence it requires thoughtful consideration of philosophers. Participants decided that to progress in solving this problem researches from various disciplines have to cooperate. (shrink)

The article also shows the primary importance of thorough research on a wide range of social and human questions that this trend in modern neuroscience raises. (shrink)

"Scientific materialism" is one of the most influential currents in modern Anglo-American philosophy. An examination of its content and the paths that have emerged for its further evolution is of prime interest for Marxist philosophers. "Scientific materialism" was born in the fifties and has developed rapidly on many levels, signaling a sharp increase in materialist tendencies in contemporary bourgeois philosophy and an attendant intensified confrontation between materialism and idealism. This, of course, deserves especially careful attention.

Army Officers face increased moral pressure in modern warfare, where character judgement and ethical judgement are vital. This article reports the results of a study of 242 junior British Army officers using the Army Intermediate Concept Measure, comprising a series of professionally oriented moral dilemmas developed for the UK context. Results are suggestive of appropriate application of Army values to the dilemmas and of ethical reasoning aligning with Army excellence. The sample does slightly less well, however, for justification than for (...) action reasoning, and there are differences following initial training for infantry and artillery officers versus other branches of service. Dilemmas involving anti-torture methods and not covering up soldiers' failings generated best results compared to those requiring balance between compassion and mission, and negotiating personal relationships with military needs. Gender differences favouring women were less than those observed for other professional groups using similar measures. This research further develops a much-needed measure of ethical reasoning among junior Army officers, with potential for use among other ranks. This approach is advocated for other professional groups. (shrink)

An introduction to category theory as a rigorous, flexible, and coherent modeling language that can be used across the sciences. Category theory was invented in the 1940s to unify and synthesize different areas in mathematics, and it has proven remarkably successful in enabling powerful communication between disparate fields and subfields within mathematics. This book shows that category theory can be useful outside of mathematics as a rigorous, flexible, and coherent modeling language throughout the sciences. Information is inherently dynamic; the same (...) ideas can be organized and reorganized in countless ways, and the ability to translate between such organizational structures is becoming increasingly important in the sciences. Category theory offers a unifying framework for information modeling that can facilitate the translation of knowledge between disciplines. Written in an engaging and straightforward style, and assuming little background in mathematics, the book is rigorous but accessible to non-mathematicians. Using databases as an entry to category theory, it begins with sets and functions, then introduces the reader to notions that are fundamental in mathematics: monoids, groups, orders, and graphs—categories in disguise. After explaining the “big three” concepts of category theory—categories, functors, and natural transformations—the book covers other topics, including limits, colimits, functor categories, sheaves, monads, and operads. The book explains category theory by examples and exercises rather than focusing on theorems and proofs. It includes more than 300 exercises, with solutions. Category Theory for the Sciences is intended to create a bridge between the vast array of mathematical concepts used by mathematicians and the models and frameworks of such scientific disciplines as computation, neuroscience, and physics.

In the early '70s he continued his analysis of the problem of scientific understanding, delineating the specific features of definitions in the theories of natural sciences and in the social science disciplines.

In this essay, David Waddington and Noah Weeth Feinstein explore how Dewey's conception of science can help us rethink the way science is done in schools. The authors begin by contrasting a view of science that is implicitly accepted by many scientists and science educators — science as a search for truth — with Dewey's instrumentalist, technological, and nonrealist conception of science. After demonstrating that the search-for-truth conception is closely linked to some ongoing difficulties with science curricula that students (...) find particularly alienating, they then analyze some of the educational opportunities that Dewey's vision opens up. Ultimately, Waddington and Weeth Feinstein argue that Dewey offers a humble and humanistic vision of science and science education practice that captures the power of science by connecting it clearly to everyday human activities and challenges.

Critics like Leonard Waks argue that video games are, at best, a dubious substitute for the rich classroom experiences that John Dewey wished to create and that, at worst, they are profoundly miseducative. Using the example of Fate of the World, a climate change simulation game, David Waddington addresses these concerns through a careful demonstration of how video games can recapture some of the lost potential of Dewey's original program of education through occupations. Not only do simulation games realize (...) most of the original goals of education through occupations, but they also solve some of the serious practical problems that Dewey's curriculum generated. Waddington concludes the essay with an analysis of Waks's critiques and some cautionary notes about why it is important to be temperate in our endorsement of educational video gaming. (shrink)

Expression of transgenes in mice, when examined with assays that can distinguish individual cells, is often found to be heterocellular, or variegated. Line‐to‐line variations in expression of a transgene may be due largely to differences in the proportion of cells in which it is expressed. Variegated silencing by centromeric heterochromatin is well described, but other factors may also affect transgene silencing in mice. Tandem arrays of transgenes themselves form heterochromatin, and some cell lineages may tend to silence transgenes because of (...) extensive facultative heterochromatin in their nuclei. The cis‐acting transcriptional control elements within a transgene inhibit silencing, and strainspecific differences in chromatin proteins may strongly influence the extent of variegation. The accessibility of multiple differentiated cell lineages in mice suggests that they may provide a tool for dissecting the role of chromatin‐mediated silencing in cell differentiation and tissue‐specific gene expression.

One of the interesting aspects of Dewey’s early educational thought is his apparent hostility toward children’s imaginative pursuits, yet the question of why this antipathy exists remains unanswered. As will become clear, Dewey’s hostility towards imaginative activities stemmed from a broad variety of concerns. In some of his earliest work, Dewey adopted a set of anti-Romantic criticisms and used these concerns to attack what one might call “runaway” imaginative and emotional tendencies. Then, in his early educational writings, these earlier concerns (...) were augmented by several other factors, including problematic trends in progressive education, new developments in psychology, and Dewey’s own educational aims. This analysis explores the roots of these criticisms, and explains how they culminate in the stance on the imagination that Dewey eventually outlined in the early educational writings. Notably, these findings have some important implications for certain prominent contemporary critics of progressivism. (shrink)

Scholars agree that Hegel had an important influence on John Dewey's early work.1 Unfortunately, the precise nature of this influence is not always easy to discern; in his early works, Dewey mentions Hegel only rarely, and seldom refers to him. However, in his letters and in his later works, Dewey concedes that Hegel had a strong influence on his philosophy. For example, in a 1930 essay, "From Absolutism to Experimentalism," Dewey acknowledges the influence of Hegel, noting that "acquaintance with Hegel (...) has left a permanent deposit in my thinking."2This paper is dedicated to the investigation of an important but not particularly well known, connection between the work of Hegel and Dewey's early educational ideas.3 ..

In a majority of cases observed in classrooms over the last several decades, what has gone by the name “discussion” is not discussion, but rather an interaction better known as recitation. If one sees this phenomenon as a problem, then an aspect of its resolution must be theoretical : What series of conceptual terms might we adopt such that recitation does not pass for discussion? Such a theoretical response would have to address internal and external, or subjective and intersubjective, phenomena (...) to describe what it means to participate in an interaction like discussion or recitation. Next the theory would have to explain the differences between interactions such as discussion and recitation in robust terms. Finally, these robust differences would have to prevent the “mistaking” of discussion for recitation, and vice versa. David Backer sets out to accomplish these three goals in the following essay. The theory he builds relies on a distinction between two psychological-affective states: dehiscence and melancholia. Backer argues that recitation forms a mass through melancholic introjection of a single object, while discussion forms a group that dehiscently introjects no particular object at all. The chief finding of this essay is that viewing discussion and recitation through the mass-psychological lens offers a new way to examine what kind of relations of influence and power form during classroom discourse and, specifically, the political significance of those discourses.
