Contrary to Pothos, rule- and similarity-based processes cannot be distinguished by dimensionality. Rather, one must consider the goal of the processing: what the system will do with the resulting representations. Research on speech perception demonstrates that the degree to which speech categories are gradient (or similarity-based) is a function of the utility of within-category variation for further processing.

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative, explanation for visual multistability – that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...) of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non-visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non-sensory brain centers. Such direct intervention in the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

It is well-known that the invocation of `equilibrium processes' in thermodynamics is oxymoronic. However, their prevalence and utility, particularly in elementary accounts, presents a problem. We consider a way in which their role can be played by sets of sequences of processes demarcated by curves carrying the property of accessibility. We also examine the vexed question of whether equilibrium processes are necessarily reversible and the revision of this property in relation to sets of sequences of such processes.

Responsible Research and Innovation provides a framework for judging the ethical qualities of innovation processes, however guidance for researchers on how to implement such practices is limited. Exploring RRI in the context of nanotechnology, this paper examines how the dispersed and interdisciplinary nature of the nanotechnology field somewhat hampers the abilities of individual researchers to control the innovation process. The ad-hoc nature of the field of nanotechnology, with its fluid boundaries and elusive membership, has thus far failed to establish a (...) strong collective agent, such as a professional organization, through which researchers could collectively steer technological development in light of social and environmental needs. In this case, individual researchers cannot innovate responsibly purely by themselves, but there is also no structural framework to ensure that responsible development of nanotechnologies takes place. We argue that, in such a case, individual researchers have a duty to collectivize. In short, researchers in situations where it is challenging for individual agents to achieve the goals of RRI are compelled to develop organizations to facilitate RRI. In this paper we establish and discuss the criteria under which individual researchers have this duty to collectivize. (shrink)

Pointing by apes is near-ubiquitous in captivity, yet rare in their natural habitats. This has implications for understanding both the ontogeny and heritability of pointing, conceived as a behavioral phenotype. The data suggest that the cognitive capacity for manual deixis was possessed by the last common ancestor of humans and the great apes. In this review, nonverbal reference is distinguished from symbolic reference. An operational definition of intentional communication is delineated, citing published or forthcoming examples for each of the defining (...) criteria from studies of manual gestures in apes. Claims that chimpanzees do not point amongst themselves or do not gesture declaratively are refuted with published examples. Links between pointing and cognitive milestones in other domains relating means to ends are discussed. Finally, an evolutionary scenario of pointing as an adaptation to changes in hominid development is briefly sketched. (shrink)

Resource extraction companies worldwide are involved with Indigenous peoples. Historically these interactions have been antagonistic, yet there is a growing public expectation for improved ethical performance of resource industries to engage with Indigenous peoples. (Crawley and Sinclair, Journal of Business Ethics 45, 361–373 (2003)) proposed an ethical model for human resource practices with Indigenous peoples in Australian mining companies. This paper expands on this work by re-framing the discussion within the context of sustainable development, extending it to Canada, and generalizing (...) to other resource industries. We argue that it is unethical to sacrifice the viability of Indigenous cultures for industrial resource extraction; it is ethical to engage with indigenous peoples in a manner consistent with their wishes and needs as they perceive them. We apply these ideas to a case study in the coastal temperate rainforest of Clayoquot Sound, British Columbia, Canada. In this case a scientific panel comprised of Nuu-Chah-Nulth elders, forest scientists and management professionals, achieved full consensus on developing sustainable forest practice standards by drawing equally on Indigenous traditional ecological knowledge and Western science in the context of one of the most heated and protracted environmental conflicts in Canadian history. The resulting sustainable forest practice standards were later adopted by leading forestry firms operating on the coast. Our analysis of this scientific panels success provides the basis for advancing an ethical approach to sustainable development with Indigenous peoples. This ethical approach is applicable to companies working in natural resource industries where the territories of Indigenous peoples are involved. (shrink)

Engineers use neural networks to control systems too complex for conventional engineering solutions. To examine the behavior of individual hidden units would defeat the purpose of this approach because it would be largely uninterpretable. Yet neurophysiologists spend their careers doing just that! Hidden units contain bits and scraps of signals that yield only arcane hints about network function and no information about how its individual units process signals. Most literature on single-unit recordings attests to this grim fact. On the other (...) hand, knowing a system's function and describing it with elegant mathematics tell one very little about what to expect of interneuronal behavior. Examples of simple networks based on neurophysiology are taken from the oculomotor literature to suggest how single-unit interpretability might decrease with increasing task complexity. It is argued that trying to explain how any real neural network works on a cell-by-cell, reductionist basis is futile and we may have to be content with trying to understand the brain at higher levels of organization.

Affective disorders arise in stressful situations from aberrant sensory information integration that affects energetic nutrient (i.e., glucose) utilization to the cognitive centers of the brain. Because energy flow is mediated by molecular signals and receptors that evolved before the first complex brains, the phylogenetically oldest signaling systems are essential in the etiology of affective disorders. The corticotropin‐releasing factor (CRF) peptide subfamily is a phylogenetically old metazoan peptide family and is pivotal for regulating organismal energy response associated with stress. Highly conserved, (...) both the CRF peptide family and its receptors possess a structural relationship to the teneurins, and their receptors, latrophilins, respectively. The CRF homologous region of teneurin is defined as the “teneurin C‐terminal associated peptide” (TCAP) and antagonizes CRF action, regulates mitochondrial energy production, and is anxiolytic in vivo. Here, it is postulated that TCAP represents an ancient peptide that mediates intercellular information transfer of stressful and noxious events by regulating energy utilization among neurons.

Henrich et al. convincingly caution against the overgeneralization of findings from particular human populations, but fail to apply their own compelling reasoning to our nearest living relatives, the great apes. Here we argue that rearing history is every bit as important for understanding cognition in other species as it is in humans.

Corballis suggests that apes lack voluntary control over their vocal production. However, recent evidence implicates voluntary control of vocalizations in apes, which suggests that intentional control of vocal communication predates the hominid-pongid split. Furthermore, the ease with which apes in captivity manipulate the visual attention of observers implies a common cognitive basis for joint attention in humans and apes.

We show that both positive and negative absolute temperatures and monotonically increasing and decreasing entropy in adiabatic processes are consistent with Carathéodory's version of the second law and we explore the modifications of the Kelvin–Planck and Clausius versions which are needed to accommodate these possibilities. We show, in part by using the equivalence of distributions and the canonical distribution, that the correct microcanonical entropy, is the surface (Boltzmann) form rather than the bulk (Gibbs) form thereby providing for the possibility of (...) negative temperatures and we counter the contention on the part of a number of authors that the surface entropy fails to satisfy fundamental thermodynamic relationships.

Comparative and developmental psychology are engaged in a search for the evolutionary and developmental origins of the perceptions of “intentions” and “desires,” and of epistemic states such as “ignorance” and “false belief.” Shanker & King (S&K) remind us that these are merely words to describe public events: All organisms that can discriminate states of “knowledge” in others have learned to do this through observation of publicly available information.

It has been argued that if an animal is psychologically like us, there may be more scientific reason to experiment upon it, but less moral justification to do so. Some scientists deny the existence of this dilemma, claiming that although there are scientifically valuable similarities between humans and animals that make experimentation worthwhile, humans are at the same time unique and fundamentally different. This latter response is, ironically, typical of pre-Darwinian beliefs in the relationship between human and non-human animals. Another (...) irony is that debate about such issues has facilitated the participation once more of philosophers in questions concerning experimental psychology: ironic because laboratory-oriented psychologists, especially since the turn of the last century, had been eager to establish the independence of their subject from any influence of philosophy and its investigative methods, as well as from any kind of anthropomorphism.In Britain, certainly more so than in the United States, ethical constraints have prevented the development of psychological research with animals along certain routes. By the 1980s British professional and academic societies had published codes of conduct and guidelines for their members, in part responding to public concern about the welfare of animals in the psychological laboratory. What led to the establishment of these codes and guidelines? This paper analyses the historical background against which professional concern for ethical cost in experimental animal psychology began to take shape, leading to the societies’ open pronouncements of the 1980s.

In the Italian universities, there was traditionally a strong alliance between natural philosophy and medicine, which however was all to the advantage of the latter; its teachers were better regarded and better paid than others in the faculty of Arts and Medicine, and this led to career paths that sought out the teaching of medicine as soon as possible. This article examines a reversal of this trend observable in sixteenth-century Bologna and some other Italian universities , leading to careers concentrating (...) on natural philosophy and on the interpretation of Aristotelian works. It appears that financial incentives were part of the context leading to specialization in philosophy. An appendix listing the careers of nearly 200 teachers of natural philosophy in Bologna between 1340 and 1600 illustrates the developments. (shrink)

The author describes how Muslims over the centuries have determined the sacred direction towards Mecca and presents two highly sophisticated Mecca-centred world-maps for finding the qibla . These recently-discovered world-maps have forced a reevaluation of Muslim achievements in mathematics and cartography.

This special issue aims to help bridge this gap: it provides a flavour of how philosophical translation in particular was conceived in Renaissance Europe. It is also meant to help stimulate a debate concerning the viewpoint of Renaissance practitioners of the art of «interpretation»: when working from Latin or Greek, did they see the activities of translation and vernacularization, for instance, as identical? Did they conceive of “vertical” and “horizontal” translations as separate, according to an influential distinction outlined by Gianfranco (...) Folena? Did they adopt a broadly similar approach to translation, regardless of whether they were dealing with literary, scientific, or religious texts? Did they think of translations as clearly separate from other forms of interpretation, such as paraphrases or other renderings? (shrink)

This article investigates the claims made in the dedicatory epistle to Girolamo Manfredi’s De homine to have effected an Italian translation of various earlier works. First published in 1474, the De homine is strongly dependent on the pseudo-Aristotelian Problems, for which several translations into Latin were available by Manfredi’s time as well as the highly influential commentary by Pietro d’Abano. Focusing on one particular section of the De homine, on voice, this article offers an analysis of the various sources used (...) and of the extent to which Manfredi is indeed offering a translation or something different. This study concludes that Manfredi closely followed the translation by Bartolomeo da Messina and the commentary by Pietro d’Abano; it finds no clear evidence of his use of the translations by George of Trebizond or Theodore Gaza. Other sources used include especially Rhazes’ Ad Almansorem. (shrink)

Peter McHugh’s influence on those of us who studied and worked with him as part of York University’s graduate sociology programme in Toronto from the mid-1970s until the late 1980s, while lasting and undeniable, is not necessarily immediately apparent nor easily articulated. What follows is a brief reflection on how this difficulty can be understood as integral to Peter McHugh’s unique contribution both to those of us fortunate enough to have studied with him, and more broadly, to the discipline of (...) sociology itself.

Herpes simplex virus (HSV)‐derived vectors are currently being developed for the introduction of foreign DNA into neurons. HSV vectors can facilitate a range of molecular studies on postmitotic neurons and may ultimately be used for somatic cell gene therapy for certain neurologic diseases. In this article, the salient features of the pathogenesis and molecular biology of HSV relevant to its use as a vector are described, along with an overview of the methods used to derive these vectors. The accomplishments which (...) have been made to date using the HSV vector system are discussed, with emphasis on the issues of this technology which remain to be addressed. HSV has the potential to be a most useful tool for neuronal cell transgenesis and it is likely that important neurobiological questions will be answered using this vector system. (shrink)

Derrida on Formal Logic: An Interpretive Essay develops the dominant themes in Jacques Derrida's texts on the principles of formal logic, especially identity and contradiction, as these themes emerged from Derrida's discussion of Joyce's Ulysses. For students of Derrida and his place as a critic of western metaphysics, the work provides a clear account and critical evaluation of implications drawn from Derrida's conclusions concerning the strength of formal logic.

Concerns about business ethics have led many business schools to integrate ethics into the curriculum, with mixed results (May, Luth, & Schwoerer 2014, Wang & Calvano 2015, Waples, Antes, Murphy, Connelly & Mumford 2009). This paper seeks to improve our understanding of business students’ ethics by looking into their identity, a cognitive lens by which students see themselves and interpret their environment (Triandis 1989) and that can be relatively malleable to priming and socializing processes (Vignoles, Schwartz, & Luyckx 2011, Ybarra (...) & Trafimow 1998). Results show that undergraduate students with higher individual and lower collective identities report lower intentions to behave ethically. Moreover, our results show that a business education has the power to influence students’ ethical intentions by altering their individual and collective identities. Our results suggest that business schools should consider the effects of their curriculum and pedagogies on the development of individual and collective identities to educate more ethical business students.

This article argues that the concept of personhood is intrinsically relational and that a relational understanding of created personhood can be derived from divine personhood and understood systematically in relation to itself, the pre-personal world and to other persons. Insofar as this set of three relationships is understood to be dislocated by sinful self-enclosedness in the penultimate reality and standing in contradiction to the ultimate reality retrospectively constituting it, the article suggests that all created personhood at present could be called (...) ‘potential’ personhood. The article then examines the concept of personhood maintained by Alberto Giubilini and Francesca Minerva in their recent paper on ‘after-birth abortion’ in comparison to Johannes Fischer’s discussion of embryonic stem cell research and personhood. In response to both, the article concludes that it is not possible at present for humans to make a concrete external identification of the divine relation that internally constitutes created personhood. As a result, the article proposes adopting a veil of ignorance with reference to the status of embryonic personhood, as it would be worse to deny the status of personhood to an actual person than to attribute personhood to a non-person.
