Knowledge concerning the cognition involved in perceiving and remembering faces has informed the design of at least two generations of facial compositing technology. These systems allow a witness to work with a computer (and a police operator) in order to construct an image of a perpetrator. Research conducted with systems currently in use has suggested that basing the construction process on the witness recalling and verbally describing the face can be problematic. To overcome these problems and make better use of (...) witness cognition, the latest systems use a combination of Principal Component Analysis (PCA) facial synthesis and an array-based interface. The present paper describes a preliminary study conducted to determine whether the use of an array-based interface really does make appropriate use of witness cognition and what issues need to be considered in the design of emerging compositing technology.

Eyewitnesses to crimes sometimes search for a culprit on social media before viewing a police lineup, but it is not known whether this affects subsequent lineup identification accuracy. The present online study was conducted to address this. Two hundred and eighty-five participants viewed a mock crime video, and after a 15–20 min delay either viewed a mock social media site including the culprit, viewed a mock social media site including a lookalike, or completed a filler task. A week later, participants (...) made an identification from a photo lineup. It was predicted that searching for a culprit on social media containing the lookalike would reduce lineup identification accuracy. There was a significant association between social media exposure and lineup accuracy for the Target Present lineup, but for the Target Absent lineup there was no significant association with lineup identification accuracy. The results suggest that if an eyewitness sees a lookalike when conducting a self-directed search on social media, they are less likely to subsequently identify the culprit in the formal ID procedure.

We consider the symbol grounding problem, and apply to it philosophical arguments against Cartesianism developed by Sellars and McDowell: the problematic issue is the dichotomy between inside and outside which the definition of a physical symbol system presupposes. Surprisingly, one can question this dichotomy and still do symbolic computation: a detailed examination of the hardware and software of serial ports shows this.

The Hungarian-born philosopher of science Imre Lakatos introduces the methodology of scientific research programs, and also makes a famous distinction between “progressive” and “degenerating” programs. Although Lakatos does not give extensive guidance as to whether philosophical rather than scientific theories could also be judged in this way, he does give some intriguing hints in his discussion of a debate on induction between Rudolf Carnap and Karl Popper. After considering two extant but misguided attempts to use “degenerating” as a polemical term (...) in philosophy, this article gathers the aforementioned hints from Lakatos and a few others from Alfred North Whitehead in an effort to identify what a “progressive philosophy” might look like.

Experience from a three-year Home Office funded evaluation of a project intended to reduce school exclusions is used to explore methodological dilemmas raised by the current emphasis upon 'evidence-based' policy formation. The social construction of school exclusion rates poses problems of reliability and validity, especially when such rates are simultaneously being used for target setting. In principle, the concept of 'evidence-based' can refer to a wide variety of research questions and appropriate research methodologies. Despite this, moves towards interpreting 'evidence-based' as (...) predominantly measurement and outcomes oriented can be found both in government evaluation guidelines and in procedures for systematic reviews of research. Given the complexity of educational innovations, any neglect of research into the processes of change in naturalistic settings will not only lead to a restricted awareness of a project's impact but also to a failure to understand what certain apparent outcomes actually mean.

Religion is more than a matter of worshipping a deity or spirit. For many people, religion pervades every part of their lives and is not separated off into some purely private and personal realm. Religion is integral to many people's relationship with the wider world, an aspect of their dwelling among other beings - both human and other-than-human - and something manifested in the everyday world of eating food, having sex and fearing strangers. Food, Sex and Strangers offers alternative ways (...) of thinking about what religion involves and how we might better understand it. Drawing on studies of contemporary religions, especially among indigenous peoples, the book argues that religion serves to maintain and enhance human relationships in and with the larger-than-human world. Fundamentally, religion can be better understood through the ways we negotiate our lives than in affirmations of belief - and it is best seen when people engage in intimate acts with themselves and others.

As support for his position, Rachlin refers to the writings of Aristotle. However, Aristotle, like many social psychological theorists, would dispute the assumptions that altruism always involves self-control, and that altruism is confined to acts that have group benefits. Indeed, for Aristotle, as for equity theory and sociobiology, justice exists partly to curb the unrestrained actions of those altruists who are a social liability.

The book sets out to address and answer three questions from the point of view of Christian theology. The first is, from where does theology speak? The second is, what are the mechanisms whereby cultures change? The third is, how might we conceive the relationship between the contemporary production of theological discourse and the transformation of cultures more generally? Drawing upon the work of standpoint epistemologists, cultural anthropologists and social scientists, the book argues that public acts of interpretation are involvements (...) in renegotiating the future direction of cultural change. Though the enquiry is conducted from one particular standpoint - Christian theology - the observations and suggestions it makes regarding cultural transformation and the defense it makes of syncretism have more general application.

This article uses the ideas of Marshall McLuhan (and to a lesser extent Martin Heidegger) to argue for a non-relational approach to architecture. The word ‘form’ is used throughout the arts and humanities, though in different ways depending on the term to which it is opposed: as in form vs. function, form vs. content, and form vs. matter. In his book The Autopoiesis of Architecture, Patrik Schumacher argues that form/function is the lead-distinction of the architectural profession. I hold that Schumacher (...) cannot be right in this claim, since form and function are both too relational in character to form a true opposition. (shrink)

Desire and its cognates—longing, yearning—do a lot of hard work in modern theology, the work grounded in philosophical precedents going back at least as far as the early German Romantics. These precedents helped to inaugurate the twentieth century explorations of psychoanalysis. And so, desire re‐entered theological conversation and some lessons were learnt; most evidently about bringing the body back to the soul and the spirit. Despite the impact of Nygren’s Agape and Eros thesis, the range ‘desire’ covers now in modern (...) theology admits no dualism between caritas and eros, and has actively promoted discussions that move fluidly between philosophy and theology. But a question remains that this essay can only begin to explore: what is desire? The question arises because, as theologians concerned with concepts closely allied to desiring, yearning, and longing—concepts such as grace, participation, friendship, love, and formation, for example—we employ it as if we knew what it is, and the mechanics of its operations are self‐evident. But desire, this essay argues, is obscure and multiple, elusive, deceptive, and slippery. And that has theological implications. (shrink)

We examine a series of disputations which Luther participated in towards the end of his career: we argue that these disputations show that Luther was very familiar with the tools of medieval formal logic, and continued to make positive theological use of them until the end of his life.

Essays on philosophy and intellectual history, focusing in particular on John Locke.

We start with Fodor's critique of cognitive science in "The mind doesn't work that way: The scope and limits of computational psychology": he argues that much mental activity cannot be handled by the current methods of cognitive science because it is nonmonotonic and, therefore, is global in nature, is not context-free, and is thus not capable of being formalized by a Turing-like mental architecture. We look at the use of nonmonotonic logic in the artificial intelligence community, particularly with the discussion (...) of the so-called frame problem. The mainstream approach to the frame problem is, we argue, probably susceptible to Fodor's critique; however, there is an alternative approach, due to McCain and Turner, which is, when suitably reformulated, not susceptible. In the course of our argument, we give a proof theory for the McCain-Turner system and show that it satisfies cut elimination. We have two substantive conclusions: first, that Fodor's argument depends on assumptions about logical form which not all nonmonotonic theories satisfy and, second, that metatheory plays an important role in the context of evolutionary accounts of rationality.
