We consider three accepted truths about iris biometrics, involving pupil dilation, contact lenses and template aging. We also consider a relatively ignored issue that may arise in system interoperability. Experimental results from our laboratory demonstrate that the three accepted truths are not entirely true, and also that interoperability can involve subtle performance degradation. All four of these problems affect primarily the stability of the match, or authentic, distribution of template comparison scores rather than the non-match, or imposter, distribution of scores. (...) In this sense, these results confirm the security of iris biometrics in an identity verification scenario. We consider how these problems affect the usability and security of iris biometrics in large-scale applications, and suggest possible remedies. (shrink)
Interpersonal neurobiology (IPNB) is a burgeoning interdisciplinary field that focuses on ways in which relationships shape and transform the architecture and functioning of the human brain. IPNB points to four specific conditions that appear to encourage the emergence of empathy. Further, these conditions, when gathered together, may constitute the core components of a spirituality of compassion. Following definitions and a discussion of interdisciplinary method, this essay delineates IPNB's main tenets and demonstrates ways in which IPNB sheds light on important aspects (...) of human empathy and compassion. Drawing on this analysis, it introduces the four conditions that encourage the emergence of empathy in individuals and groups and shows why they may be central elements of a spirituality of compassion. A case study, in which the Native American Ojibwe practice of the talking circle is described and assessed through the lens of the IPNB-derived spirituality of compassion, demonstrates the evaluative usefulness of this set of conditions.

Experiments with young infants provide evidence for early-developing capacities to represent physical objects and to reason about object motion. Early physical reasoning accords with 2 constraints at the center of mature physical conceptions: continuity and solidity. It fails to accord with 2 constraints that may be peripheral to mature conceptions: gravity and inertia. These experiments suggest that cognition develops concurrently with perception and action and that development leads to the enrichment of conceptions around an unchanging core. The experiments challenge claims (...) that cognition develops on a foundation of perceptual or motor experience, that initial conceptions are inappropriate to the world, and that initial conceptions are abandoned or radically..

Abstract. What kind of consciousness is best prepared to undertake effective interdisciplinary explorations in religion and science in our twenty-first century context? This paper draws on the thought of theologian David Tracy and psychologist and philosopher of religion James W. Jones to suggest that negation and ecstasy are mutually conditioning factors that go into the shaping of just such a consciousness. Healthy, constructive modes of relating to the disciplinary other imply the emergence of a transformed way of knowing and being (...) wherein the scholar countenances the loss of controlling and autonomous ways of relating (negation), and precisely in that loss, enters into shared spaces of mutually illuminative and transformative understanding (ecstasy).

Karen Barad develops a view she calls ‘posthumanism,’ or ‘agential realism,’ where the human is reconfigured away from the central place of explanation, interpretation, intelligibility, and objectivity to make room for the epistemic importance of other material agents. Barad is not alone in this kind of endeavor, but her posthumanism offers a unique epistemological position. Her aim is to take a performative rather than a representationalist approach to analyzing ‘socialnatural’ practices and challenge methodological assumptions that may go unnoticed in (...) some disciplinary fields. Yet for all the good of the challenge, Barad must support it with sound epistemological theorizing, theorizing that would apply to any methodology, whether that be sociological, historical, anthropological, or philosophical. Thus, where one might critique Barad on her assessments of sociological, historical, or anthropological incorporations of humans and the nonhuman, I critique Barad’s epistemology on its sense of objectivity and dismissal of the centrality of the human. I argue that Barad’s epistemology must retain a particular form of humanism, a humanism that stakes human subjectivity as the locus of rationality and objectivity, without which it creates intractable problems. To recuperate Barad’s challenge to contest assumptive distinctions while avoiding her epistemological problems, I offer some parting reflections. (shrink)
Karen Warren claims that there is a “logic of domination” at work in the oppressive conceptual frameworks informing both sexism and naturism. Although her account of the principle of domination as a connection between oppressions has been an influential one in ecofeminist theory, it has been challenged by recent criticism. Both Karen Green and John Andrews maintain that the principle of domination,as Warren articulates it, is ambiguous. The principle, according to Green, admits of two possible readings, each of (...) which she finds flawed. Similarly, Andrews claims that the principle is fundamentally inadequate because it cannot distinguish cases of oppressive domination from cases of nonoppressive domination. In this paper, I elucidate Warren’s views and defend her against these and other criticisms put forward by Green and Andrews. I show that Warren’s account of “the logic of domination” successfully illuminates important conceptual features of oppression. (shrink)

Feminist and post-colonial epistemologists, philosophers of science, and thinkers more generally may find themselves in a distinct form of difficult situation regarding their access to and authority over knowledge within the academic world. Because feminist and post-colonial approaches to knowledge require an acute awareness of relations of domination and the ways in which these pervade the social and epistemic world, it is often difficult to know how to proceed in making theory. These theorists are in particularly ripe positions to benefit (...) from what philosopher-physicist Karen Barad offers us. In this paper, I engage with parts of Karen Barad’s theory of agential realism, both critically and self-reflexively. I assert that allowing Barad’s theory to inform and structure our thinking and language makes knowers better able to meet certain requirements of epistemological responsibility, particularly with regard to the ways we make theory. Moreover, I attempt to assert this in a way that is mindful of how her theory speaks to and accounts for my doing so. (shrink)
The Exclusion Problem (EP) for mental causation suggests that there is a tension between the claim that the mental causes physical effects, and the claim that the mental does not overdetermine its physical effects. In response, Karen Bennett (2008, 2003) puts forward an extra necessary condition for overdetermination: if one candidate cause were to occur but the other were not to occur, the effect would still occur. She thus denies one of the assumptions of EP, the assumption that if (...) an effect has two sufficient causes, it is overdetermined. If sound, her argument does two things: it solves EP, and it shows how to use counterfactuals in order to make the notion of overdetermination precise. However, the argument is not sound. (shrink)
Transformations are not only conditioned by facts encompassing narrower or wider panoramas: from concentrating on death and one (political) role (the ode of Horace), through recalling Cleopatra’s mature life and love (the drama of Shakespeare), to creating an image embracing the heroine’s whole life with its numerous roles, but as a mother and a daughter in the first place, because even her lovers resemble a father and a child (the fictional biography of Karen Essex). Above all, they appear to (...) be more connected with different attitudes towards universal references lying within human cognitive abilities. Horace’s didactic opposition of contradictory patterns leads to the victory of one of them — and it is a linear pattern, as an equivalent of modern myth, which is accepted by the author himself. In Shakespeare, it takes a form of tragedy resulting from the fragmentary character of each pattern, one of which introduces change (archaic myth) and the other constancy (modern myth), and from a painful attempt to combine them. In Essex, the vision of the world in which archaic myth, strongly represented by a child, triumphs is utopian. Irrespective of the differences, all the works realize the essential role played by images developed by heroes, and especially by authors, in human cognition. (shrink)

This study examines the use of a video news release in a specific story. Press coverage and editorial criticism in the case showed that journalists do not articulate sufficiently how the news owners' sway, through institutional controls, can lead to a hegemony of expedient action in the newsroom. Critical self-reflection by news workers will better enable journalists to ethically deliberate news choices that balance their responsibilities to owners, peers, and the public.
This article attempts to define karma as both action and the effects of action. In terms of the effects or fruits of action, the effect of action upon the mind is the focus; thus, the idea of "effect" is primarily defined as psychic residue and is compared to Freud's notion of memory traces. In addition, action that produces karma is said to be accompanied by the "pulling" feeling of volition (cetanÄ). Some comparisons are then made between cetanÄ and the theories (...) of Karen Horney in Western psychology vis Ã vis her view of the neurotic's compulsive, driven feelings. The article also has a more ethically oriented side. Often, the karma doctrine is believed to be the only causal factor responsible for one's present condition, and thus, a person's unfortunate circumstances: sometimes this notion leads to blaming a person for his or her misfortune. This article seeks to discover whether or not this idea truly has scriptural backing. Lastly, the article explores the issue of whether or not one must always live out the entirety of the effects of one's actions or if it is possible to purify or eliminate actions' effects before they come to fruition. For this question in particular, the article examines both TheravÄda and MahÄyÄna thinking. (shrink)
