The combination of breeding for increased production and the intensification of housing conditions have resulted in increased occurrence of behavioral, physiological, and immunological disorders. These disorders affect health and welfare of production animals negatively. For future livestock systems, it is important to consider how to manage and breed production animals. In this paper, we will focus on selective breeding of laying hens. Selective breeding should not only be defined in terms of production, but should also include traits related to animal (...) health and welfare. For this we like to introduce the concept of robustness. The concept of robustness includes individual traits of an animal that are relevant for health and welfare. Improving robustness by selective breeding will increase (or restore) the ability of animals to interact successfully with the environment and thereby to make them more able to adapt to an appropriate husbandry system. Application of robustness into a breeding goal will result in animals with improved health and welfare without affecting their integrity. Therefore, in order to be ethically acceptable, selective breeding in animal production should accept robustness as a breeding goal. (shrink)

Primordial emotions are the subjective element of the instincts which are the genetically programmed behaviour patterns which contrive homeostasis. They include thirst, hunger for air, hunger for food, pain and hunger for specific minerals etc.There are two constituents of a primordial emotion—the specific sensation which when severe may be imperious, and the compelling intention for gratification by a consummatory act. They may dominate the stream of consciousness, and can have plenipotentiary power over behaviour.It is hypothesized that early in animal evolution (...) complex reflex mechanisms in the basal brain subserving homeostatic responses, in concert with elements of the reticular activating system subserving arousal, melded functionally with regions embodied in the progressive rostral development of the telencephalon. This included the emergent limbic and paralimbic areas, and the insula. This phylogenetically ancient organization subserved the origin of consciousness as the primordial emotion, which signalled that the organisms existence was immediately threatened. Neuroimaging confirms major activations in regions of the basal brain during primordial emotions in humans. The behaviour of decorticate humans and animals is discussed in relation to the possible existence of primitive awareness.Neuroimaging of the primordial emotions reveals that rapid gratification of intention by a consummatory act such as ingestion causes precipitate decline of both the initiating sensation and the intention. There is contemporaneous rapid disappearance of particular regions of brain activation which suggests they may be part of the jointly sufficient and severally necessary activations and deactivations which correlate with consciousness [Crick, F. & Koch, C. . A framework for consciousness. NatureNeuroscience,6, 119–126]. (shrink)

The essays in this volume examine the nature of human flourishing and its relationship to a variety of other key concepts in moral theory. Some of them trace the link between flourishing and human nature, asking whether a theory of human nature can allow us to develop an objective list of goods that are of value to all agents, regardless of their individual purposes or aims. Some essays look at the role of friendships or parent-child relationships in a good life, (...) or seek to determine whether an ethical theory based on human flourishing can accommodate concern for others for their own sake. Other essays analyze the function of families or other social-political institutions in promoting the flourishing of individuals. Still others explore the implications of flourishing for political theory, asking whether considerations of human flourishing can help us to derive principles of social justice. (shrink)

This collection of essays is dedicated to the memory of the late Harvard philosopher Robert Nozick, who died in 2002. The publication of Nozick's Anarchy, State, and Utopia in 1974 revived serious interest in natural rights liberalism, which, beginning in the latter half of the eighteenth century, had been eclipsed by a succession of antithetical political theories including utilitarianism, progressivism, and various egalitarian and collectivist ideologies. Some of our contributors critique Nozick's political philosophy. Other contributors examine earlier figures in the (...) liberal tradition, most notably John Locke, whose Second Treatise of Government, published in the late seventeenth century, profoundly influenced the American founders. The remaining authors analyze natural rights liberalism's central doctrines. (shrink)

Background: The factors influencing parents’ willingness to enroll their children in biobanks are poorly understood. This study sought to assess parents’ willingness to enroll their children, and their perceived benefits, concerns, and information needs under different consent and data-sharing scenarios, and to identify factors associated with willingness. Methods: This large, experimental survey of patients at the 11 eMERGE Network sites used a disproportionate stratified sampling scheme to enrich the sample with historically underrepresented groups. Participants were randomized to receive one of (...) three consent and data-sharing scenarios. Results: In total, 90,000 surveys were mailed and 13,000 individuals responded (15.8% response rate). 5737 respondents were parents of minor children. Overall, 55% (95% confidence interval 50–59%) of parents were willing to enroll their youngest minor child in a hypothetical biobank; willingness did not differ between consent and data-sharing scenarios. Lower educational attainment, higher religiosity, lower trust, worries about privacy, and attitudes about benefits, concerns, and information needs were independently associated with less willingness to allow their child to participate. Of parents who were willing to participate themselves, 25% were not willing to allow their child to participate. Being willing to participate but not willing to allow one’s child to participate was independently associated with multiple factors, including race, lower educational attainment, lower annual household income, public health care insurance, and higher religiosity. Conclusions: Fifty-five percent of parents were willing to allow their youngest minor child to participate in a hypothetical biobank. Building trust, protecting privacy, and addressing attitudes may increase enrollment and diversity in pediatric biobanks. (shrink)

What constitutes a just tax system, and what are its moral foundations? Should a society's tax regime be designed to achieve a just distribution of wealth among its citizens, or should such a regime be designed to promote economic growth, rising standards of living, and increasing levels of employment? Are these two goals compatible or incompatible? Why should justice not require, or at least lead to, an increase in general prosperity? The essays in this volume examine the history of tax (...) policies and the normative principles that have informed the selection of various types of taxes and tax regimes; economic data to discover which tax policies lead to economic growth; particular theories of justice or property rights regarding the design of tax systems; and other essays propose specific tax reforms. Still others challenge traditional theories of taxation, offering new ways of understanding the fiscal relationship between governments and their citizens. (shrink)

In this collection, twelve philosophers, historians, and political philosophers-scholars with a diverse set of disciplinary and political leanings-assess aspects of socialism in light of its recent reversals. Some of the essays consider what made the socialist project seem compelling to its advocates, examining the moral and political values that made socialism appealing to intellectuals. Others evaluate whether there are aspects of socialism that ought to be preserved, such as its quest for equality and community. Some essays examine whether free-market systems (...) need to be further modified in response to ongoing socialist critiques. Several others argue for the continuing validity of socialism in its social democratic incarnation, suggesting ways in which socialism may still have a productive future. Still others condemn the socialist project as inherently misguided in theory, while also portraying 'really existing socialism' as cataclysmic in practice. (shrink)

A central idea in moral and political philosophy, 'autonomy' is generally understood as some form of self-governance or self-direction. Certain Stoics, modern philosophers such as Spinoza, and most importantly, Immanuel Kant, are among the great philosophers who have offered important insights on the concept. Some theorists analyze autonomy in terms of the self being moved by its higher-order desires. Others argue that autonomy must be understood in terms of acting from reason or from a sense of moral duty independent of (...) the passions. Autonomy seems closely related to the notion of freedom, but in what sense: freedom from coercion, freedom from psychological constraints, or freedom from material necessity? Various approaches to these and similar questions yield different implications for public policy. Is capitalism, social democracy or socialism more favorable to autonomy? The essays in this volume address these important questions. (shrink)

In this collection, thirteen prominent philosophers and political scientists address the nature of liberalism, its origins, and its meaning and proper interpretation. Some essays examine the writings of liberalism's earliest defenders, like John Locke and Adam Smith, or the influence of classical liberalism on the American founders. Some focus on the Progressive movement and the rise of the administrative state, while others defend particular conceptions of liberalism or examine liberal theories of justice, including those of John Rawls and Robert Nozick. (...) Several essays discuss the U.S. Constitution, seeking to determine whether it is best viewed as empowering the federal government to achieve certain ends, or as strictly limiting its power to ensure the broadest freedom for individuals to pursue their own ends. Other essays address the limits of economic freedom or focus on the nature and extent of property rights and the government's power of eminent domain. (shrink)

Is there a moral obligation to reduce differences in income and wealth? There is an egalitarian tradition that condemns these differences, particularly as they arise in free-market capitalist society, as unfair or unjust. The opponents of this view argue that the material disparities of capitalist society have been brought about by voluntary mechanisms and thus accord with the freely exercised liberties of its citizens. They conclude that capitalist inequality is not vulnerable to the ethical complaints of its critics. They maintain (...) that the standard of living achieved as a by-product of the marketplace and its inequalities could not be adequately reproduced under egalitarian institutions. The essays in this volume, written by prominent economists, philosophers, and academic lawyers, assess the empirical and theoretical questions raised by inequalities of income and wealth. (shrink)

The vegetation eaten by animals on large areas of several continents is deficient in phosphate and deleterious effects on physiology, particularly reproduction, ensue. Records on bone chewing behaviour by both pastoral andwild game animals extend over two centuries. In laboratory investigation of this apt behaviour it has been shown that the appetite for bones is innate and specific and cued predominantly by olfactory stimuli. It is suppressed by rapidly increasing the plasma phosphate concentration to normal but not influenced by increasing (...) the phosphate concentration in cerebrospinal fluid. The central organization of this genetically programmed behaviour appears to differ from systems subserving thirst and sodium appetite. (shrink)

The idea of a role in nursing that includes expertise in ethics has been around for more than 30 years. Whether or not one subscribes to the idea that nursing ethics is separate and distinct from bioethics, nursing practice has much to contribute to the ethical practice of healthcare, and with the strong grounding in ethics and aspiration for social justice considerations in nursing, there is no wonder that the specific role of the nurse ethicist has emerged. Nurse ethicists, expert (...) in nursing practice and the application of ethical theories and concepts, are well positioned to guide nurses through complex ethical challenges. However, there is limited discussion within the field regarding the specific job responsibilities that the nurse ethicist ought to have. The recent appearance of job postings with the title “nurse ethicist” suggest that some healthcare institutions have identified the value of a nurse in the practice of ethics and are actively recruiting. Discomfort about the possibility of others defining the role of the nurse ethicist inspired this paper (and special issue). If the nurse ethicist is to be seen as an integral part of addressing ethical dilemmas and ethical conflicts that arise in healthcare, then nurse ethicists ought to be at the forefront of defining this role. In this paper, we draw upon our own experiences as nurse ethicists in large academic healthcare systems to describe the essential elements that ought to be addressed in a job description for a nurse ethicist practicing in a clinical setting linked to academic programs. Drawing upon our experience and the literature, we describe how we perceive the nurse ethicist adds value to healthcare organizations and teams of professional ethicists. (shrink)

BACKGROUND: Alzheimer's disease is intimately tied to amyloid-beta peptide. Extraneuronal brain plaques consisting primarily of Abeta aggregates are a hallmark of AD. Intraneuronal Abeta subunits are strongly implicated in disease progression. Protein sequence mutations of the Abeta precursor protein account for a small proportion of AD cases, suggesting that regulation of the associated gene may play a more important role in AD etiology. The APP promoter possesses a novel 30 nucleotide sequence, or "proximal regulatory element" , at -76/-47, from the (...) +1 transcription start site that confers cell type specificity. This PRE contains sequences that make it vulnerable to epigenetic modification and may present a viable target for drug studies. We examined PRE-nuclear protein interaction by gel electrophoretic mobility shift assay and PRE mutant EMSA. This was followed by functional studies of PRE mutant/reporter gene fusion clones. RESULTS: EMSA probed with the PRE showed DNA-protein interaction in multiple nuclear extracts and in human brain tissue nuclear extract in a tissue-type specific manner. We identified transcription factors that are likely to bind the PRE, using competition gel shift and gel supershift: Activator protein 2 , nm23 nucleoside diphosphate kinase/metastatic inhibitory protein , and specificity protein 1 . These sites crossed a known single nucleotide polymorphism . EMSA with PRE mutants and promoter/reporter clone transfection analysis further implicated PuF in cells and extracts. Functional assays of mutant/reporter clone transfections were evaluated by ELISA of reporter protein levels. EMSA and ELISA results correlated by meta-analysis. CONCLUSIONS: We propose that PuF may regulate the APP gene promoter and that AD risk may be increased by interference with PuF regulation at the PRE. PuF is targeted by calcium/calmodulin-dependent protein kinase II inhibitor 1, which also interacts with the integrins. These proteins are connected to vital cellular and neurological functions. In addition, the transcription factor PuF is a known inhibitor of metastasis and regulates cell growth during development. Given that APP is a known cell adhesion protein and ferroxidase, this suggests biochemical links among cell signaling, the cell cycle, iron metabolism in cancer, and AD in the context of overall aging.

Virtues, broadly understood as stable and robust dispositions for certain responses across morally relevant situations, have been a growing topic of interest in psychology. A central topic of discussion has been whether studies showing that situations can strongly influence our responses provide evidence against the existence of virtues (as a kind of stable and robust disposition). In this review, we examine reasons for thinking that the prevailing methods for examining situational influences are limited in their ability to test dispositional stability (...) and robustness; or, then, whether virtues exist. We make the case that these limitations can be addressed by aggregating repeated, cross-situational assessments of environmental, psychological and physiological variables within everyday life—a form of assessment often called ecological momentary assessment (EMA, or experience sampling). We, then, examine how advances in smartphone application (app) technology, and their mass adoption, make these mobile devices an unprecedented vehicle for EMA and, thus, the psychological study of virtue. We, additionally, examine how smartphones might be used for virtue development by promoting changes in thought and behavior within daily life; a technique often called ecological momentary intervention (EMI). While EMA/I have become widely employed since the 1980s for the purposes of understanding and promoting change amongst clinical populations, few EMA/I studies have been devoted to understanding or promoting virtues within non-clinical populations. Further, most EMA/I studies have relied on journaling, PDAs, phone calls and/or text messaging systems. We explore how smartphone app technology provides a means of making EMA a more robust psychological method, EMI a more robust way of promoting positive change, and, as a result, opens up new possibilities for studying and promoting virtues.

This article describes some potential uses of Bayesian estimation for time-series and panel data models by incorporating information from prior probabilities in addition to observed data. Drawing on econometrics and other literatures we illustrate the use of informative “shrinkage” or “small variance” priors while extending prior work on the general cross-lagged panel model. Using a panel dataset of national income and subjective well-being we describe three key benefits of these priors. First, they shrink parameter estimates toward zero or toward each (...) other for time-varying parameters, which lends additional support for an income → SWB effect that is not supported with maximum likelihood. This is useful because, second, these priors increase model parsimony and the stability of estimates and thus improve out-of-sample predictions and interpretability, which means estimated effect should also be more trustworthy than under ML. Third, these priors allow estimating otherwise under-identified models under ML, allowing higher-order lagged effects and time-varying parameters that are otherwise impossible to estimate using observed data alone. In conclusion we note some of the responsibilities that come with the use of priors which, departing from typical commentaries on their scientific applications, we describe as involving reflection on how best to apply modeling tools to address matters of worldly concern.

The Patient Self Determination Act of 1991 brought much needed attention to the importance of advance care planning and surrogate decision-making. The purpose of this law is to ensure that a patient’s preferences for medical care are recognized and promoted, even if the patient loses decision-making capacity. In general, patients are presumed to have DMC. A patient’s DMC may come under question when distortions in thinking and understanding due to illness, delirium, depression or other psychiatric symptoms are identified or suspected. (...) Physicians and other healthcare professionals working in hospital settings where medical illness is frequently comorbid with depression, adjustment disorders, demoralization and suicidal ideation, can expect to encounter ethical tension when medically sick patients who are also depressed or suicidal request do not resuscitate orders.

Disfluencies include editing terms such as uh and um as well as repeats and revisions. Little is known about how disfluencies are processed, and there has been next to no research focused on the way that disfluencies affect structure-building operations during comprehension. We review major findings from both computational linguistics and psycholinguistics, and then we summarize the results of our own work which centers on how the parser behaves when it encounters a disfluency. We describe some new research showing that (...) information associated with misarticulated verbs lingers, and which adds to the large body of data on the critical influence of verb argument structures on sentence comprehension. The paper also presents a model of disfluency processing. The parser uses a Tree Adjoining Grammar to build phrase structure. In this approach, filled and unfilled pauses affect the timing of Substitution operations. Repairs and corrections are handled by a mechanism we term “Overlay,” which allows the parser to overwrite an undesired tree with the appropriate, correct tree. This model of disfluency processing highlights the need for the parser to sometimes coordinate the mechanisms that perform garden-path reanalysis with those that do disfluency repair. The research program as a whole demonstrates that it is possible to study disfluencies systematically and to learn how the parser handles filler material and mistakes. It also showcases the power of Tree Adjoining Grammars, a formalism developed by Aravind Joshi which has yielded results in many different areas of linguistics and cognitive science. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to Bertrand RussellPeter H. DentonNicholas Griffin, editor. The Cambridge Companion to Bertrand Russell. New York: Cambridge University Press, 2003. Pp. xvii + 550. Cloth, $75.00. Paper, $26.00.It is a daunting task to conceive of a single companion to Bertrand Russell, who in life as in thought was never content with a single anything. Nicholas Griffin has brought his customary expertise to the project, and in (...) snaring fourteen other contributors to this volume, has produced a welcome addition to an academic's library of Russell materials.The shape of the volume, its contents and its presentation, however, unfortunately reflect the lopsided nature of current Russell studies. One hopes for a companion volume that has the breadth of the earlier volume edited fifty years ago by Paul Schilpp, but in vain. This book is overwhelmingly about Russell before 1918, almost entirely about philosophy of mathematics, epistemology and logic, and several of the pieces easily could have been included in a festschrift for Frege instead.What is included is well done, but to call it "the most convenient and accessible guide to Russell available" is to speak in comparative terms. To be fair, it sets out to focus on a narrow definition of Russell's contributions to modern philosophy, and the contributors accomplish this task. Ian Grattan-Guinness writes on "Mathematics in and behind Russell's Logicism, and its Reception," a subject that continues into "Bertrand Russell's Logicism" by Martin Godwyn and Andrew D. Irvine. The roots of analytic philosophy are of primary concern in this volume, so Richard L. Cartwright explores "Russell and Moore, 1898-1905" and Michael Beaney relates "Russell and Frege." "The Theory of Descriptions" by Peter Hylton sets up two pieces on "Russell's Substitutional Theory" (Gregory Landini) and "The Theory of Types" (Alasdair Urquhart), while Paul Hager's "Russell's Method of Analysis" leads into "Russell's Neutral Monism" (R.E.Tully) and "The Metaphysics of Logical Atomism" (Bernard Linsky).The next portion of the book expands the intellectual focus somewhat, with "Russell's Structuralism and the Absolute Description of the World" by William Demopoulos—perhaps [End Page 349] the best in a series of good papers—and "From Knowledge by Acquaintance to Knowledge by Causation" by Thomas Baldwin. Approaching the end of the book, Anthony Grayling's essay on "Russell, Experience, and the Roots of Science" remains firmly planted in the pre-1918 milieu, though his tentative commentary on Human Knowledge at least glimmers the extension of Russell's intellectual life into the post-Great War period.Effectively the entire second half of Russell's life is left to the final contributor, Charles Pidgen, for commentary. Author of Russell on Ethics, much of Pigden's short essay here ("Bertrand Russell: Moral Philosopher or Unphilosophical Moralist?") somewhat plaintively directs the reader to his book for an elaboration of why Russell is worth reading after 1918, at least on the subject of ethics. Of the other authors, only Hager (317) observes the extent to which Russell's post-War work mistakenly has been ignored.The book concludes with a selective bibliography. The audience, for the most part, is a specialist one, with only some essays accessible to the general reader. On that score, Griffin's introduction and his own essay, "Russell's Philosophical Background," are easily the most readable. At the risk of quibbling, I was disturbed by the uneven production of the book, as each author set his own standard for footnotes, endnotes and bibliography (creating a jumble of styles). Even within individual contributions, there are a number of inconsistencies in notation as well as typographical errors.By the end, I was left hoping there might be a second companion volume for Bertrand Russell, one that reflects what he spent the last fifty years of his life thinking, writing, and doing. In the absence of such material (which is of far greater popular interest today just as it was in Russell's lifetime), this book by itself is more of a companion to current Russell studies than to Bertrand Russell himself.Peter H.

Major hallmarks of Alzheimer's disease include brain deposition of the amyloid-beta peptide , which is proteolytically cleaved from a large Abeta precursor protein by beta and gamma- secretases. A transmembrane aspartyl protease, beta-APP cleaving enzyme , has been recognized as the beta-secretase. We review the structure and function of the BACE1 protein, and of 4129 bp of the 5'-flanking region sequence of the BACE1 gene and its interaction with various transcription factors involved in cell signaling. The promoter region and 5'-untranslated (...) region contain multiple transcription factor binding sites, such as AP-1, CREB and MEF2. A 91 bp fragment is the shortest region with significant reporter gene activity and constitutes the minimal promoter element for BACE1. The BACE1 promoter contains six unique functional domains and three structural domains of increasing sequence complexity as the "ATG" start codon is approached. Notably, the BACE1 gene promoter contains basal regulatory elements, inducible features and sites for regulation by various important transcription factors. Herein, we also discuss and speculate how the interaction of these transcription factors with the BACE1 promoter can modulate synaptic plasticity, neuronal apoptosis and oxidative stress, which are pertinent to the pathogenesis and progression of AD.

Variations in levels of apolipoprotein E have been tied to the risk and progression of Alzheimer's disease . Our group has previously compared and contrasted the promoters of the mouse and human ApoE gene promoter sequences and found notable similarities and significant differences that suggest the importance of the APOE promoter's role in the human disease. We examine here three specific single-nucleotide polymorphisms within the human APOE promoter region, specifically at -491 , -427 , and at -219 upstream from the (...) +1 transcription start site. The -219 and -491 polymorphic variations have significant association with instance of AD, and -491AA has significant risk even when stratified for the APOEepsilon4 allele. We also show significant effects on reporter gene expression in neuronal cell cultures, and, notably, these effects are modified by species origin of the cells. The -491 and -219 polymorphisms may have an interactive effect in addition to any independent activity. DNA-protein interactions differ between each polymorphic state. We propose SP1 and GATA as candidates for regulatory control of the -491 and -219 polymorphic sites. This work's significance lies in drawing connection among APOE promoter polymorphisms' associations with AD to functional promoter activity differences and specific changes in DNA-protein interactions in cell culture-based assays. Taken together, these results suggest that APOE expression levels are a risk factor for AD irrespective of APOEepsilon4 allele status. (shrink)

Denommer, c'est appeler les etres et les choses par le nom qui leur a ete institue dans et par la langue. Assurant l'intercomprehension entre les locuteurs, la denomination constitue une propriete fondamentale du lexique et des terminologies. Si epistemologiquement, la denomination fait partie integrante des appareils conceptuel et methodologique de la Linguistique et de la Terminologie, dans l'une et l'autre discipline elle connait une situation paradoxale. D'une part elle souffre d'un deficit important de conceptualisation; de l'autre elle se revele etre (...) un puissant moteur pour la description semantique et referentielle du lexique et des terminologies. L'objet du present ouvrage est de proposer un reexamen systematique et explicite de cette notion et de lui assurer un positionnement valide dans l'appareil theorique de la Linguistique. Refusant une caracterisation monolithique, l'analyse opte pour une conception modulaire, articulee sur les differents parametres combinables et superposables qui definissent cette propriete: ontologiques, sociolinguistiques, juridiques et linguistiques. L'objectif de ce travail est egalement heuristique: envisager la denomination comme un levier en vue du reexamen du concept de polysemie, qui lui est consubstantiellement lie. Appliquee aux modeles categoriels et non categoriels, la denomination permet de distinguer entre emplois relevant effectivement d'une polysemie lexicale de ceux procedant d'effet impartis aux instanciations de vocables.

Previous research has demonstrated that hormones, relationship goals, and social context influence interest in the opposite sex. It has not been previously reported, however, whether having a current sexual partner also influences interest in members of the opposite sex. To test this, we obtained explicit and implicit measures of interest by measuring men’s and women’s subjective ratings and response times while they evaluated photos of opposite-sex faces. Fifty-nine men and 56 women rated 510 photos of opposite-sex faces for realism, masculinity, (...) attractiveness, or affect. We found that these subjective ratings were not influenced by partner status in either men or women. However, women who did not report having a current sexual partner spent more time evaluating the photos than women who did have partners, demonstrating greater interest in the photos. Sexual partner status did not predict men’s response times. These findings may reveal that relationship commitment in women suppresses interest in alternative partners. (shrink)
