Since the publication of the successful animal trials of the Biobag, a prototypical extrauterine support for extremely premature neonates, numerous ethicists have debated the potential implications of such a device. Some have argued that the Biobag represents a natural evolution of traditional newborn intensive care, while others believe that the Biobag would create a new class of being for the patients housed within. Kingma and Finn argued inBioethicsfor making a categorical distinction between fetuses, newborns and ‘gestatelings’ in a Biobag on (...) the basis of a conceptual distinction between ectogenesis versus ectogestation. Applying their arguments to the clinical realities of newborn intensive care, however, demonstrates the inapplicability of their ideas to the practice of medicine. Here, I present three clinical examples of the difficulty and confusion their argument would create for clinicians and offer a possible remedy: namely, discarding the term ‘artificial womb’ in favour of ‘Biobag’.

Human cognition is said to be systematic: cognitive ability generalizes to structurally related behaviours. The connectionist approach to cognitive theorizing has been strongly criticized for its failure to explain systematicity. Demonstrations of generalization notwithstanding, I show that two widely used networks (feedforward and recurrent) do not support systematicity under the condition of local input/output representations. For a connectionist explanation of systematicity, these results leave two choices, either: (1) develop models capable of systematicity under local input/output representations; or (2) justify the (...) choice of similarity-based (nonlocal) component representations sufficient for systematicity. (shrink)

At root, the systematicity debate over classical versus connectionist explanations for cognitive architecture turns on quantifying the degree to which human cognition is systematic. We introduce into the debate recent psychological data that provides strong support for the purely structure-based generalizations claimed by Fodor and Pylyshyn (1988). We then show, via simulation, that two widely used connectionist models (feedforward and simple recurrent networks) do not capture the same degree of generalization as human subjects. However, we show that this limitation is (...) overcome by tensor networks that support relational processing. (shrink)

This is a study of the development of Western inwardness from Plato to Augustine. It traces the origin of three concepts: inward turn, private inner space, and outward expression. All three were originally theological concepts; i.e., they belonged to philosophical theories that related God to the soul. ;Part I examines the precursors of these three concepts in Plato, then notes the central contribution made by Aristotle's doctrine that the mind is identical with the Forms it knows. This allows Plotinus to (...) identify the divine Mind with the intelligible world and locate it within the soul. This then is the foundation of Plotinus' inward turn: in turning its mind into its own interior, the soul is turning to the divine. ;Part II argues that it was Augustine who invented the concept of a private inner space of the self. Augustine's search for God builds on Plotinus' inward turn, but must adjust to the fact that Christian doctrine denies the divinity of the soul. Hence the inner self in Augustine is no longer the intelligible world, but the soul's own inner world. It only becomes a private world, however, inasmuch as the soul is fallen and therefore separated from other souls by the opacity of mortal bodies. (shrink)

What we must do is step back and take a grand view of the perspectives in order to understand it on a more particular level. If we can picture all of God’s attributes on a bar graph scale, all of God’s attributes would max out at 100% each. These attributes are always operating at 100%; at no time does any attribute diminish or decrease below 100%. However, there are times when one of His attributes shows forth more than another does, (...) but they are all operating at a maximum level. (shrink)

To properly understand behavior, we must obtain both ultimate and proximate explanations. Put briefly, ultimate explanations are concerned with why a behavior exists, and proximate explanations are concerned with how it works. These two types of explanation are complementary and the distinction is critical to evolutionary explanation. We are concerned that they have become conflated in some areas of the evolutionary literature on human behavior. This article brings attention to these issues. We focus on three specific areas: the evolution of (...) cooperation, transmitted culture, and epigenetics. We do this to avoid confusion and wasted effort—dangers that are particularly acute in interdisciplinary research. Throughout this article, we suggest ways in which misunderstanding may be avoided in the future. (shrink)

Contrary to the ecumenical spirit of our time, the differences among the Christian religions bring into question what one can say or do in common with fellow Christians. This issue, echoing the program of this journal, accentuates those differences, specifically when we focus on the Christian who is ill and suffering. At the bedside, it is the specifics of a religion, including not only its doctrines, but its informing and sustaining narratives, that must particularly be brought into play for the (...) sake of the patient. Given this, our focus in this article regards what such a view implies for the clinician who is caring for a Christian patient whose religion he mayor may not share, in general or in its specifics. Our basic conclusion is that the tendency for the clinician to act as both the patient's spiritual counselor, as well as his clinician, is generally neither prudent nor appropriate. Both hats should not be worn concurrently. This view is advanced not only because of concerns regarding patient vulnerability and the possible abuse of power, but also because the two roles may collide with or undermine each other. (shrink)

Biomarkers can be powerful tools to guide diagnosis, treatment, and research. However, prudent use of biomarkers requires formal validation efforts. Although the data needed for biomarker validation has traditionally been hard to access, new research initiatives can ease this process.

The FDA's new table of surrogate endpoints used for drug approvals is an important step forward for overseeing the use of biomarkers in clinical trials. Nevertheless, we present several ways in which the table can be improved.

This introductory article explains the theme of this book, which is about political theory. It evaluates the impact of literature that proved especially influential in framing debate through the last decades of the twentieth century and opening years of the twenty-first and examines the historical work on political thought. It describes the combination of concerns that runs through the work of John Rawls, Ronald Dworkin, and the liberal egalitarian tradition and identifies areas of debate that have proved particularly fruitful over (...) the last thirty years. It analyses political theory from a global perspective and discusses body politic. (shrink)

The collapse of confidence in anonymization as a robust approach for preserving the privacy of personal data has incited an outpouring of new approaches that aim to fill the resulting trifecta of technical, organizational, and regulatory privacy gaps left in its wake. In the latter category, and in large part due to the growth of Big Data–driven biomedical research, falls a growing chorus of calls for criminal and penal offences to sanction wrongful re-identification of “anonymized” data. This chorus cuts across (...) the fault lines of polarized privacy law scholarship that at times seems to advocate privacy protection at the expense of Big Data research or vice versa. Focusing on Big Data in the context of biomedicine, this article surveys the approaches that criminal or penal law might take toward wrongful re-identification of health data. It contextualizes the strategies within their respective legal regimes as well as in relation to emerging privacy debates focusing on personal data use and data linkage and assesses the relative merit of criminalization. We conclude that this approach suffers from several flaws and that alternative social and legal strategies to deter wrongful re-identification may be preferable. (shrink)

Working memory limits are best defined in terms of the complexity of the relations that can be processed in parallel. Complexity is defined as the number of related dimensions or sources of variation. A unary relation has one argument and one source of variation; its argument can be instantiated in only one way at a time. A binary relation has two arguments, two sources of variation, and two instantiations, and so on. Dimensionality is related to the number of chunks, because (...) both attributes on dimensions and chunks are independent units of information of arbitrary size. Studies of working memory limits suggest that there is a soft limit corresponding to the parallel processing of one quaternary relation. More complex concepts are processed by or In segmentation, tasks are broken into components that do not exceed processing capacity and can be processed serially. In conceptual chunking, representations are to reduce their dimensionality and hence their processing load, but at the cost of making some relational information inaccessible. Neural net models of relational representations show that relations with more arguments have a higher computational cost that coincides with experimental findings on higher processing loads in humans. Relational complexity is related to processing load in reasoning and sentence comprehension and can distinguish between the capacities of higher species. The complexity of relations processed by children increases with age. Implications for neural net models and theories of cognition and cognitive development are discussed. (shrink)

Bouts of exercise performed either prior to or immediately following study periods enhance encoding and learning. Empirical evidence supporting the benefits of interventions that simultaneously pair physical activity with material to be learned is not conclusive, however. A narrative, theory-based review of dual-task experiments evaluated studies in terms of arousal theories, attention theories, cognitive-energetic theories, and entrainment theories. The pattern of the results of these studies suggests that cognitive-motor interference can either impair or enhance memory of semantic information and the (...) manner in which physical activity impacts working memory within executive processing appears to explain disparate outcomes. The integration and timing of physical movements in concert with the type of information to be encoded and remembered appears to be a critical requirement for learning. These observations have implications for the role of physical activity in education, rehabilitation, and gerontological settings. (shrink)

The core issue of our target article concerns how relational complexity should be assessed. We propose that assessments must be based on actual cognitive processes used in performing each step of a task. Complexity comparisons are important for the orderly interpretation of research findings. The links between relational complexity theory and several other formulations, as well as its implications for neural functioning, connectionist models, the roles of knowledge, and individual and developmental differences, are considered.

International law guarantees rights to indigenous peoples regarding traditional lands, knowledge, cultural preservation, and human security. This paper will examine the sources of these rights and legal remedies for violations of law. Protection of indigenous peoples’ cultures and resources contribute to the protection of the global environment.

Toward A Sociological Imagination builds on the ideas C. Wright Mills expressed in The Sociological Imagination for an approach to the scientific method broad enough to open up to the full range of knowledge within the sociology discipline. In this book, nine sociologists and one philosopher provide detailed tests of the utility of the approach within diverse substantive sociological areas.

The Aristotelian categories are a fundamental element in Eriugena’s philosophical system on account of his realist view of dialectic. He received his texts concerning the categories from Boethius and the De decem catagoriis, but key ideas in his treatment of them—namely, the metaphysical importance of dialectic, the unknowability of essence, and the origin of being in place and time, ideas fundamentally rooted in Byzantine developments of the Christology of Chalcedon—are taken from Maximus the Confessor. Eriugena’s work on the categories represents (...) an attempt, much misunderstood, to assimilate the richness of the Eastern tradition to Western philosophical and theological method. This paper examines the synthesis of Maximus’s ideas with Ciceronian and Boethian elements in Eriugena’s striking treatment of the Aristotelian Categories. (shrink)
