We give a historical overview of the development of almost 50 years of empirical research on the affordances in the past and in the present. Defined by James Jerome Gibson in the early development of the Ecological Approach to Perception and Action as the prime of perception and action, affordances have become a rich topic of investigation in the fields of human movement science and experimental psychology. The methodological origins of the empirical research performed on affordances can be traced back (...) to the mid 1980’s and the works of Warren (1984, 1988) and Michaels (1988). Most of the research in Ecological Psychology performed since has focused on the actualization of discretely defined actions, the perception of action boundaries, the calculation of pi-numbers, and the measurement of response times. The research efforts have resulted in advancements in the understanding of the dynamic nature of affordances, affordances in a social context and the importance of calibration for perception of affordances. Although affordances are seen as an instrumental part of the control of action most studies investigating affordances do not pay attention to the control of the action. We conclude that affordances are still primarily treated as a utility to select behaviour, which creates a conceptual barrier that hinders deeper understanding of affordances. A focus on action-boundaries has largely prevented advancement in other aspects of affordances, most notably an integrative understanding of the role of affordances in the control of action.

A guide for scientists who would like to contribute to the professional development of science teachers for elementary schools. Based on information from over 180 programs, describes what activities work and why, and suggests how to identify programs teachers have found to be effective and take the initial steps to become involved. Also provides vignettes illustrating the daily work of science teachers. Annotation copyright by Book News, Inc., Portland, OR.

Stalk‐eyed flies of the family Diopsidae exhibit a unique form of hypercephaly, which has evolved under both natural and sexual selection. Male hypercephaly is used by female diopsids as an indicator of male quality. By choosing to mate with males expressing the most‐exaggerated hypercephaly, females can benefit both from the enhanced fertility of these males and the transmission of other heritable advantages to their offspring. Stalk‐eyed flies are close relatives of the model organism, Drosophila melanogaster. We have shown that similar (...) genetic and cellular mechanisms regulate the initial development of the head capsule in fruitflies and diopsids. The great diversity of stalk‐eyed fly species, exhibiting varying degrees of hypercephaly and sexual dimorphism, constitutes a major advantage for comparative studies of their development and evolution.

This text provides a straightforward, lively but rigorous, introduction to truth-functional and predicate logic, complete with lucid examples and incisive exercises, for which Warren Goldfarb is renowned.

The role of paleontology in evolutionary biology between the publication of The Origin of Species in 1859 and the Evolutionary Synthesis of the 1940s is frequently described as mostly misguided failure. However, a significant number of American and British PDPS invertebrate paleontologists of this period did devote considerable attention to evolution, and their evolutionary theories and conclusions were a good deal more diverse and nuanced than previous histories have suggested. This paper brings into focus a number of important but underrecognized (...) aspects of the history of paleontology within the history of biology, including that PDPS paleontologists were not all as theoretically backward as they have been portrayed; that the post-Synthesis narrative of the history of evolution should be continually reevaluated, in part to decouple historical understanding from the agendas of authors who have used history to advance particular views of evolution; and that there is a much richer story to be told about the history of evolutionary biology in both the pre- and post-Synthesis eras.

The “therapeutic obligation” is a physician’s duty to provide his patients with what he believes is the best available treatment. We begin by discussing some prominent formulations of the obligation before raising two related considerations against those formulations. First, they do not make sense of cases where doctors are permitted to provide suboptimal care. Second, they give incorrect results in cases where doctors are choosing treatments in challenging epistemic environments. We then propose and defend an account of the therapeutic obligation (...) that solves the problems that undermined previous efforts at formulating the TO. We conclude by considering how apparent problems with our proposal actually rest on difficulties with informed consent. (shrink)

Observing that standard accounts of constitutional law - both the "conservative" and "liberal" varieties - have lost their power to illuminate, The Constitution and the Pride of Reason explores how constitutional law hangs together (and how it falls apart) by investigating the perennial claim that the Constitution and its interpretation somehow embody a commitment to governance by "reason". What does this claim mean, and is it valid? In confronting these queries, Smith offers revealing and iconoclastic assessments of constitutionalists ranging (...) from Madison and Jefferson to Dworkin and Bork. Also detailed in these pages is a provocative overview of the whole constitutional project, from its noble aspirations to its tragic failures. (shrink)

The use of Web 2.0 technologies in the classroom is becoming more widespread, as educators begin to recognise their use as effective learning and teaching tools. Web 2.0 facilitates new modes of social interaction that offer the potential to enrich university educational activities. New roles, structures and activities can be enabled, engendering new forms of creativity and increasing the availability of and extent of access to information. Yet in achieving this, such platforms shift the traditional boundaries between educators and their (...) students, between personal and professional lives, raising issues of integrity and pedagogy in unexpected ways. This paper reflects on three personal narratives to examine some of these challenges; the authors conclude by highlighting concerns that universities need to address. (shrink)

In "primitive" cultures, dual symbolic classification systems draw rigid temporal and spatial boundaries between the sacred and the profane. The right and left hands are described as sacred and profane, respectively. Durkheim saw a weakening of these systems as an aspect of modernization. A weakening of such dichotomous reason is shown in two examples. First, Hertz's study of the suppression of the left hand among the Maori links the left hand to the right cerebral hemisphere of the brain. The further (...) inference he might have drawn, but did not, is that the right hemisphere and its pattern thinking might play a significant role in magic, sorcery, and witchcraft. The Maori physical confinement of the left hand is no longer practiced. Second, in the United States, Hugdahl et al. present data from eight one‐decade cohorts showing that the decrease in left‐handedness by age was countered by a corresponding increase in left‐to‐right hand switching. A lower life‐span by left handers might account for some of the change across age cohorts, but at least half of the decrease in manifest left‐handedness was accounted for by a gradual decrease in social pressure not to use the left hand. Implications for the moral solidarity of postmodern society are discussed. (shrink)

The article discusses the failure of the current positivistic and materialist business ethics paradigms to adequately deal with the enormity of the contemporary business ethics crisis. Citing behavioural research into the linkage between beliefs, values and behaviour, the author suggests spiritual renewal as a solution based on the ‘fallenness’ of mankind and the reality of human evil. The concept of faith, obedience and the resulting ‘kingdom consciousness’ is explored as a basis for spiritual renewal leading to behavioural change. The process (...) of renewal is depicted as a synergistic, mutually supportive relationship between faith and action. (shrink)
