A categorical structure suitable for interpreting polymorphic lambda calculus (PLC) is defined, providing an algebraic semantics for PLC which is sound and complete. In fact, there is an equivalence between the theories and the categories. Also presented is a definitional extension of PLC including "subtypes", for example, equality subtypes, together with a construction providing models of the extended language, and a context for Girard's extension of the Dialectica interpretation.

Integrated pest management (IPM) has been widely promoted in the developing world, but in many regions its adoption rates have been variable. Experience has shown that to ensure IPM adoption, the complexities of local agro-production systems and context-specific folk knowledge need to be appreciated. Our research explored the linkages between farmer knowledge, pest management decision making, and ecological attributes of subsistence maize agriculture. We report a case study from four rural communities in the highlands of southeast Honduras. Communities were typified (...) by their agro-environments, IPM training history, and levels of infestation by a key maize pest, the fall armyworm (Spodoptera frugiperda Smith). Although variable, infestation levels generally did not justify pest management intervention. Consequently, crop losses from this pest were considered of low importance and most farmers proceeded in a rational fashion by refraining from action in their fields. Farmers attributed the low degree of pest infestation predominantly to abiotic causal factors (rainfall, temperature). The role of natural enemies in controlling this pest (i.e., biological control) was deemed of low importance by farmers; nevertheless, a broad array of such organisms was mentioned by farmers as operating in their maize crop. Farmers’ knowledge of natural enemies only partially matched scientific knowledge and was associated with the ecological features of their respective field settings. Local knowledge about natural enemies was mainly restricted to abundant and easily observable predatory species. Farmers who were knowledgeable about biological control were also familiar with a larger variety of pest management alternatives than uninformed farmers. Management options covered a wide range of curative techniques, including conservation biological control. Farmers who relied on insecticides to manage pest outbreaks knew less about biological control and pesticide alternatives. In contrast, farmers who received IPM training mentioned more types of natural enemies and were familiar with a broader range of alternative pest management tactics. Our research suggests that IPM training modifies local knowledge to better fit its environmental context. This paper provides insights in the environmental context of local agro-ecological knowledge and its linkage with pest management decision making. It also constitutes a basis for modifying IPM extension programs to deliver locality-specific technologies while strengthening the local knowledge base. (shrink)

Clinical ethics consultation is largely outside the scope of regulation and oversight, despite its importance. For decades, the bioethics community has been unable to reach a consensus on whether there should be accountability in this work, as there is for other clinical activities that influence the care of patients. The American Society for Bioethics and Humanities, the primary society of bioethicists and scholars in the medical humanities and the organizational home for individuals who perform CEC in the United States, has (...) initiated a two‐step quality attestation process as a means to assess clinical ethics consultants and help identify individuals who are qualified to perform this role. This article describes the process. (shrink)

Nanomedicine is yielding new and improved treatments and diagnostics for a range of diseases and disorders. Nanomedicine applications incorporate materials and components with nanoscale dimensions where novel physiochemical properties emerge as a result of size-dependent phenomena and high surface-to-mass ratio. Nanotherapeutics and in vivo nanodiagnostics are a subset of nanomedicine products that enter the human body. These include drugs, biological products, implantable medical devices, and combination products that are designed to function in the body in ways unachievable at larger scales. (...) Nanotherapeutics andin vivonanodiagnostics incorporate materials that are engineered at the nanoscale to express novel properties that are medicinally useful. These nanomedicine applications can also contain nanomaterials that are biologically active, producing interactions that depend on biological triggers. Examples include nanoscale formulations of insoluble drugs to improve bioavailability and pharmacokinetics, drugs encapsulated in hollow nanoparticles with the ability to target and cross cellular and tissue membranes and to release their payload at a specific time or location, imaging agents that demonstrate novel optical properties to aid in locating micrometastases, and antimicrobial and drug-eluting components or coatings of implantable medical devices such as stents.

This paper outlines a first attempt to model the special constraints that arise in language processing in conversation, and to explore the implications such functional considerations may have on language typology and language change. In particular, we focus on processing pressures imposed by conversational turn-taking and their consequences for the cultural evolution of the structural properties of language. We present an agent-based model of cultural evolution where agents take turns at talk in conversation. When the start of planning for the (...) next turn is constrained by the position of the verb, the stable distribution of dominant word orders across languages evolves to match the actual distribution reasonably well. We suggest that the interface of cognition and interaction should be a more central part of the story of language evolution. (shrink)

This handbook provides a critical guide to the most central proposition in modern linguistics: the notion, generally known as Universal Grammar, that a universal set of structural principles underlies the grammatical diversity of the world's languages. Part I considers the implications of Universal Grammar for philosophy of mind and the philosophy of language, and examines the history of the theory. Part II focuses on linguistic theory, looking at topics such as explanatory adequacy and how phonology and semantics fit into Universal (...) Grammar. Parts III and IV look respectively at the insights derived from UG-inspired research on language acquisition, and at comparative syntax and language typology, while part V considers the evidence for Universal Grammar in phenomena such as creoles, language pathology, and sign language. The book will be a vital reference for linguists, philosophers, and cognitive scientists. (shrink)

This volume of twelve specially commissioned essays about species draws on the perspectives of prominent researchers from anthropology , botany, developmental psychology , the philosophy of biology and science, protozoology, and zoology . The concept of species has played a focal role in both evolutionary biology and the philosophy of biology , and the last decade has seen something of a publication boom on the topic (e.g., Otte and Endler 1989; Ereshefsky 1992b; Paterson 1994; lambert and Spence 1995; Claridge, Dawah, (...) and Wilson 1997; Wheeler and Meier 1999; Howard and Berlocher 1998).

Why and under what conditions are individuals altruistic to family and friends in their social networks? Evolutionary psychology suggests that such behaviour is primarily the product of adaptations for kin- and reciprocal altruism, dependent on the degree of genetic relatedness and exchange of benefits, respectively. For this reason, individuals are expected to be more altruistic to family members than to friends: whereas family members can be the recipients of kin and reciprocal altruism, friends can be the recipients of reciprocal altruism (...) only. However, there is a question about how the effect of kinship is implemented at the proximate psychological level. One possibility is that kinship contributes to some general measure of relationship quality (such as ‘emotional closeness’), which in turn explains altruism. Another possibility is that the effect of kinship is independent of relationship quality. The present study tests between these two possibilities. Participants (N= 111) completed a self-report questionnaire about their willingness to be altruistic, and their emotional closeness, to 12 family members and friends at different positions in their extended social networks. As expected, altruism was greater for family than friends, and greater for more central layers of the network. Crucially, the results showed that kinship made a significant unique contribution to altruism, even when controlling for the effects of emotional closeness. Thus, participants were more altruistic towards kin than would be expected if altruism was dependent on emotional closeness alone – a phenomenon we label a ‘kinship premium’. These results have implications for the ongoing debate about the extent to which kin relations and friendships are distinct kinds of social relationships, and how to measure the ‘strength of ties’ in social networks.

Research on social influences often distinguishes between social and quality incentives to ascribe meaning to the value that popularity conveys. This study examines the neural correlates of those incentives through which popularity influences preferences. This research reports an functional magnetic resonance imaging experiment and a behavioral task in which respondents evaluated popular products with three focus perspectives; unspecified focus, focus on social aspects, and focus on quality. The results show that value derived with a social focus reflects inferences of approval (...) and reward value, and positively affects preferences. Value derived with a quality focus reflects inferences of quality and negatively affects preferences. This study provides evidence of two distinct inferential routes on both a neurological level, represented by different regions in the brain, and a behavioral level. These results provide the first evidence that a single popularity cue can in different ways influence the value derived from product popularity. (shrink)

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

This qualitative study indentifies how corporate responsibility (CR) practices are diffused to companies, as well as the factors that influence this diffusion process. Forest companies, industry associations, non-governmental organizations, and academics in Brazil, Canada, and the United States participated in this interview-based study. Data emerging from a grounded theory approach revealed three factors influencing the diffusion of CR practices to companies: (1) external contextual characteristics, (2) connectors, and (3) experts and expert organizations. These three factors influence each other, meaning that (...) the diffusion process of CR practices is somewhat cyclic. These interactions are usually manifested by companies and expert organizations influencing each other’s actions, being influenced by the external environment, and contributing to the CR trends that are observed in the external environment.

Iconicity, the resemblance between the form of a word and its meaning, has effects on behavior in both communicative symbol development and language learning experiments. These results have invited speculation about iconicity being a key feature of the origins of language, yet the presence of iconicity in natural languages seems limited. In a diachronic study of language change, we investigated the extent to which iconicity is a stable property of vocabulary, alongside previously investigated psycholinguistic predictors of change. Analyzing 784 English (...) words with data on their historical forms, we found that stable words are higher in iconicity, longer in length, and earlier acquired during development, but that the role of frequency and grammatical category may be less important than previously suggested. Iconicity is revealed as a feature of ultra-conserved words and potentially also as a property of vocabulary early in the history of language origins. (shrink)

If the world itself is metaphysically indeterminate in a specified respect, what follows? In this paper, we develop a theory of metaphysical indeterminacy answering this question.

I argue here that God, as Molinism conceives Him, is complicit in moral evil. This is of course a problem because complicity in evil undermines divine perfection. I argue, however, that it is a problem that Open Theism, as a theory of “general” (as opposed to “meticulous”) providence, avoids. This claim opposes that of Neal Judisch, who has recently (2012) argued that theories of general providence (e.g., Open Theism) are in no better position to answer the problem of gratuitous evil (...) (i.e., the evidential problem of evil) than theories of meticulous providence (e.g., Molinism or Calvinism). Here, Judisch draws on important insights about just what these theories involve in terms of gratuitous evil to diffuse what he calls “the argument for divine complicity.” In response, I offer a reformulation of this argument that is immaterial to the question of gratuitous evil. I then explain why my argument does not convict an Open Theist God and, in the course of doing so, I consider whether an application of the doctrine of double effect exonerates a Molinist God as well.

This book argues that the Russian-British philosopher Isaiah Berlin should primarily be understood through British idealism. Though he adopted Kantian methodology and a view of people as purposive beings, he rejected the Idealists' monism and theories of positive liberty. Robert A. Kocis demonstrates how, like Michael Oakeshott and R. G. Collingwood, Berlin can be seen as a 'post-Idealist' thinker, invested in the implications of that rich tradition.

Composite beings (“monsters”) are those mythical creatures composed of a mix of different anatomical forms. There are several scholarly claims for why these appear in the imagery and lore of many societies, including claims that they are found near-universally as well as those arguments that they co-occur with particular sociocultural arrangements. In order to evaluate these claims, we identify the presence of composite monsters cross-culturally in a global sample of societies, the Standard Cross-Cultural Sample. We find that composite beings are (...) not universal, and that their presence or absence co-varies most significantly with social stratification and transportation technology. This supports hypotheses that the cultural evolution of composite monsters is driven by human concerns with social distinctions within societies as well as increased contact with distant peoples.

Kant’s theory of evil, presented most fully in his Religion within the Boundaries of Mere Reason, has been consistently misinterpreted since he first presented it. As a result, readers have taken it to be a mess of inconsistencies and eccentricities and so have tried to mine it for an insight or two, dismissed it altogether, or sought to explain how Kant could have gone so wrong. In this work, I provide an interpretation of Kant’s theory of evil that renders it (...) consistent and plausible. The main problem Kant tries to solve with his theory of evil is the problem of willful immorality: how can someone who sees her moral obligations as overridingly authoritative willingly (and so culpably) transgress them? Kant’s answer is that we do so by indulging various “moral fantasies” – ways of reconceiving the moral law or one’s status in relation to it. By entertaining, e.g., the fantasy that one is exempt from the moral law’s commands (“the exceptionalist fantasy”), or that one cannot live up to them (“despondency”), or that one need only to live up to society’s standards rather than moral demands (“the adequacy fantasy”) – one persuades oneself that the duty the moral law demands one to perform is only optional. Moral fantasies appeal only because of the presence, in everyone, of the “propensity to evil,” which makes the moral law’s commands seem less authoritative, thereby strengthening one’s sensuous desires. As a result, moral fantasies thereby diminish the urgency of moral obligations, and so tempt us to entertain them. Scholars of Kant have missed this explanation of wickedness because they have restricted their attention to the Religion, a work whose gnomic statements on evil are difficult to interpret when isolated from the larger context of Kant’s thinking. Assaying Kant’s thinking on immorality from the mid-1780s to the late 1790s shows that Kant’s main concern with evil was not so much its nature, but its very possibility. Evaluating the Religion in this context reveals it to be a fruitful resource for explaining the moral psychology of immorality, a problem we still deal with today, and that is possibly. (shrink)
