To account for category-specific semantic deficits, Humphreys and Forde propose to fractionate semantic memory into multiple sensory and functional knowledge stores. There are reasons to doubt the empirical productivity of this proposal, unless theoretically motivated principles of distinguishing and weighting the different kinds of object knowledge can be spelled out in detail.

We take a fresh look at the logics of informational dependence and independence of Hintikka and Sandu and Väänänen, and their compositional semantics due to Hodges. We show how Hodges’ semantics can be seen as a special case of a general construction, which provides a context for a useful completeness theorem with respect to a wider class of models. We shed some new light on each aspect of the logic. We show that the natural propositional logic carried by the semantics (...) is the logic of Bunched Implications due to Pym and O’Hearn, which combines intuitionistic and multiplicative connectives. This introduces several new connectives not previously considered in logics of informational dependence, but which we show play a very natural rôle, most notably intuitionistic implication. As regards the quantifiers, we show that their interpretation in the Hodges semantics is forced, in that they are the image under the general construction of the usual Tarski semantics; this implies that they are adjoints to substitution, and hence uniquely determined. As for the dependence predicate, we show that this is definable from a simpler predicate, of constancy or dependence on nothing. This makes essential use of the intuitionistic implication. The Armstrong axioms for functional dependence are then recovered as a standard set of axioms for intuitionistic implication. We also prove a full abstraction result in the style of Hodges, in which the intuitionistic implication plays a very natural rôle. (shrink)

Synthesizing self‐regulatory theories, we provide new insights into the antecedents of abusive supervision. We, from the perspective of supervisor's self‐regulatory resources depletion or impairment, introduce supervisor hindrance stress as an underlying mechanism of the subordinate deviance–abusive supervision relationship: this mediated relationship will be intensified at the level of high subordinate job performance. In addition, we develop a complex contingency model and propose a three‐way interaction (i.e., subordinate deviance, job performance, supervisor outcome dependence) to obtain the complete understanding of the subordinate (...) deviance–abusive supervision relationship facilitated through the supervisors’ hindrance stress. To test our moderated moderated mediation model, we gathered time‐lagged and multisource data from a large food service company located in southern China. We collected data at two different points (i.e., Time 1 and Time 2) from supervisors and their direct reports (N = 298 responses from 68 supervisors and 298 direct reports), and findings provide support for the hypothesized moderated moderated mediation model of our study. We highlight the implications of our study for theory, research, and practice. (shrink)

This study utilises philosophical deliberation to analyse the psycho-social and emotional conflicts that arise out of widowhood practices in the Luo community ofKenya. Towards this end, it explores the attendant effects of Luo widowhood practices on family, power and gender relations, and suggests resolutions to thechallenges they generate.

Nelkin presents a simple and natural account of freedom and moral responsibility which responds to the great variety of challenges to the idea that we are free and responsible, before ultimately reaffirming our conception of ourselves as agents. Making Sense of Freedom and Responsibility begins with a defense of the rational abilities view, according to which one is responsible for an action if and only if one acts with the ability to recognize and act for good reasons. The view is (...) compatibilist -- that is, on the view defended, responsibility is compatible with determinism -- and one of its striking features is a certain asymmetry: it requires the ability to do otherwise for responsibility when actions are praiseworthy, but not when they are blameworthy. In defending and elaborating the view, Nelkin questions long-held assumptions such as those concerning the relation between fairness and blame and the nature of so-called reactive attitudes such as resentment and forgiveness. Her argument not only fits with a metaphysical picture of causation -- agent-causation -- often assumed to be available only to incompatibilist accounts, but receives positive support from the intuitively appealing Ought Implies Can Principle, and establishes a new interpretation of freedom and moral responsibility that dovetails with a compelling account of our inescapable commitments as rational agents.

With the growth of neuroscience research, new neuroscience and society (NeuroX) fields like neuroethics, neurolaw, neuroarchitecture, neuroeconomics, and many more have emerged. In this article we report on lessons learned about mentoring students in the interdisciplinary space of neuroscience and society. We draw on our experiences with the recently launched Dana Foundation Career Network in Neuroscience & Society. This resource supports educators and practitioners mentoring students aiming to apply neuroscience in diverse fields beyond medicine and biomedical science. Through our (...) programming, we identified three key lessons: (1) students are interested in exploring a wide range of neuroscience and society intersections; (2) outreach to underserved institutions generates avenues for students to join NeuroX conversations; and (3) by offering free access to online NeuroX resources and a network of subject-matter experts, the Career Network joins many partners helping to bridge the gap between neuroscience and society.

This insightful book explores the experiences of African students in the U.S. Using the personal stories of eleven African students, the book confronts the question, what is it like for Africans to leave their heritage and home, and become students in the U.S.? Being an African Student will promote curricula that is more effective and attentive to the needs of international students.

We present a game semantics for Linear Logic, in which formulas denote games and proofs denote winning strategies. We show that our semantics yields a categorical model of Linear Logic and prove full completeness for Multiplicative Linear Logic with the MIX rule: every winning strategy is the denotation of a unique cut-free proof net. A key role is played by the notion of history-free strategy; strong connections are made between history-free strategies and the Geometry of Interaction. Our semantics incorporates a (...) natural notion of polarity, leading to a refined treatment of the additives. We make comparisons with related work by Joyal, Blass, et al. (shrink)

Responsibility, blameworthiness in particular, has been characterized in a number of ways in a literature in which participants appear to be talking about the same thing much of the time. More specifically, blameworthiness has been characterized in terms of what sorts of responses are fair, appropriate, and deserved in a basic way, where the responses in question range over blame, sanctions, alterations to interpersonal relationships, and the reactive attitudes, such as resentment and indignation. In this paper, I explore the relationships (...) between three particular theses: (i) the claim that one is blameworthy to the extent that it is fair to impose sanctions, (ii) the claim that one is blameworthy to the extent that one deserves sanctions, and (iii) the claim that one is blameworthy to the extent that it is appropriate to respond with reactive attitudes. Appealing to the way in which luck in the outcome of an action can justifiably affect the degree of sanctions received, I argue that (i) is false and that fairness and desert come apart. I then argue that the relationship between the reactive attitudes and sanction is not as straightforward as has sometimes been assumed, but that (ii) and (iii) might both be true and closely linked. I conclude by exploring various claims about desert, including ones that link it to the intrinsic goodness of receiving what is deserved and to the permissibility or rightness of inflicting suffering.

The cerebral cortex is a rich and diverse structure that is the basis of intelligent behavior. One of the deepest mysteries of the function of cortex is that neural processing times are only about one hundred times as fast as the fastest response times for complex behavior. At the very least, this would seem to indicate that the cortex does massive amounts of parallel computation.This paper explores the hypothesis that an important part of the cortex can be modeled as a (...) connectionist computer that is especially suited for parallel problem solving. The connectionist computer uses a special representation, termed value unit encoding, that represents small subsets of parameters in a way that allows parallel access to many different parameter values. This computer can be thought of as computing hierarchies of sensorimotor invariants. The neural substrate can be interpreted as a commitment to data structures and algorithms that compute invariants fast enough to explain the behavioral response times. A detailed consideration of this model has several implications for the underlying anatomy and physiology. (shrink)

Much attention has been focused in recent years on the ethical acceptability of physicians receiving gifts from drug companies. Professional guidelines recognize industry gifts as a conflict of interest and establish thresholds prohibiting the exchange of large gifts while expressly allowing for the exchange of small gifts such as pens, note pads, and coffee. Considerable evidence from the social sciences suggests that gifts of negligible value can influence the behavior of the recipient in ways the recipient does not always realize. (...) Policies and guidelines that rely on arbitrary value limits for gift-giving or receipt should be reevaluated. (shrink)

With the continual development of artificial intelligence and smart computing in recent years, quantitative approaches have become increasingly popular as an efficient modeling tool as they do not necessitate complicated mathematical models. Many nations have taken steps, such as transitioning to online schooling, to decrease the harm caused by coronaviruses. Inspired by the demand for technology in early education, the present research uses a radial basis function neural network modeling technique to predict preschool instructors’ technology usage in classes based on (...) recognized determinant characteristics of technology acceptance. In this regard, this study utilized the RBFNN approach to predict preschool teachers’ technology acceptance behavior, based on the theory of planned behavior, which states that behavioral achievement, in our case the actual technology use in class, depends on motivation, intention and ability, and behavioral control. Thus, this research design is based on an adapted version of the technology acceptance model with eight dimensions: D1. Perceived usefulness, D2. Perceived ease of use, D3. Perceived enjoyment, D4. Intention to use, D5. Actual use, D6. Compatibility, D7. Attitude, and D8. Self-efficacy. According to the TAM, actual usage is significantly predicted by the other seven dimensions used in this research. Instead of using the classical multiple linear regression statistical processing of data, we opted for a NN based on the RBF approach to predict the actual usage behavior. This study included 182 preschool teachers who were randomly chosen from a project-based national preschool teacher training program and who responded to our online questionnaire. After designing the RBF function with the actual usage as an output variable and the other seven dimensions as input variables, in the model summary, we obtained in the training sample a sum of squares error of 37.5 and a percent of incorrect predictions of 43.3%. In the testing sample, we obtained a sum of squares error of 14.88 and a percent of incorrect predictions of 37%. Thus, we can conclude that 63% of the classified data are correctly assigned to the models’ dependent variable, i.e., actual technology use, which is a significant rate of correct predictions in the testing sample. This high significant percentage of correct classification represents an important result, mainly because this is the first study to apply RBFNN’s prediction on psychological data, opening up a new interdisciplinary field of research.

ABSTRACT Zora Neale Hurston's Barracoon teaches us distinct lessons about African American literary studies and its relation to the memory of Africa. In this text, Kossula helps us better understand a transatlantic black identity, the tension that exist between those who remember Africa and those who have adopted a black American identity, and the failures of supposed victories and African emigration. This traversing also reminds us that there can be no agreed upon or stable method for charting literary history. Instead, (...) it encourages us to follow a model of historiography that looks for continuity and is more cross-directional than vertical. The archive, of course, requires such a model. Thus, Barracoon's publication, as an archival artifact especially, is also instructive as evidence of the primacy of the archive in relation to canon formation and literary traditions. (shrink)

There are powerful skeptical challenges to the idea that we are free. And yet, it seems simply impossible for us to shake the sense that we really are free. Some are convinced that the skeptical challenges are insurmountable and resign themselves to living under an illusion, while others argue that the challenges can be met. Even among those who believe that our sense of ourselves as free is at least roughly accurate, there are deep differences of opinion concerning what freedom (...) requires. On the one hand, there are “libertarians” about freedom, those who believe both that we are free and that freedom requires the falsity of determinism. On the other hand, there are “compatibilists”, those who believe that freedom is compatible with determinism. While there is an impressive variety of arguments and motivations available on all sides of the debate over freedom, our inescapable sense of ourselves as free has played a recurrent and key role in the debate, sometimes explicit and sometimes not. In this paper, I explore one way that our self-conception has been used by libertarians against compatibilists, and I argue that the reasoning employed is not convincing. The libertarian appeal to our self-conception hinges on locating in each of us an essential commitment to indeterminism, or, more cautiously, a commitment to something that, with the addition of a few plausible (if not self-evident) premises, entails indeterminism. The idea, then, is that we are “natural” indeterminists, seeing our actions as undetermined (or, again, more cautiously, as having qualities that, upon reflection, we can recognize entail the falsity of determinism). By itself, this is not an argument to the effect that we are correct in 1 believing that our actions are undetermined, or to the effect that freedom requires indeterminism. But if we are in fact natural indeterminists when it comes to our own actions, then that fact serves as important motivation for libertarianism, especially if our supposed natural indeterminism captures our unshakeable sense of freedom. Kant famously located our sense of freedom in our nature as rational agents, claiming that we must act under the “idea of freedom.”2 This has suggested to many that: (R) Rational deliberators, in virtue of their very nature as rational deliberators, must represent themselves as free..

Abramsky, S., Domain theory in logical form, Annals of Pure and Applied Logic 51 1–77. The mathematical framework of Stone duality is used to synthesise a number of hitherto separate developments in theoretical computer science.• Domain theory, the mathematical theory of computation introduced by Scott as a foundation for detonational semantics• The theory of concurrency and systems behaviour developed by Milner, Hennesy based on operational semantics.• Logics of programsStone duality provides a junction between semantics and logics . Moreover, the underlying (...) logic is geometric, which can be computationally interpreted as the logic of observable properties—i.e., properties which can be determined to hold of a process on the basis of a finite amount of information about its execution.These ideas lead to the following programme. A metalanguage is introduced, comprising• types = universes of discourse for various computational situations;• terms = PROGRAMS = syntactic intensions for models or points. A standard denotational interpretation of the metalanguage is given, assigning domains to types and domain elements to terms. The metalanguage is also given a logical interpretation, in which types are interpreted as propositional theories and terms are interpreted via a program logic, which axiomatises the properties they satisfy. The two interpretations are related by showing that they are Stone duals of each other. Hence, semantics and logic are guaranteed to be in harmony with each other, and in fact each determines the other up to isomorphism. This opens the way to a whole range of applications. Given a denotational description of a computational situation in our metalanguage, we can turn the handle to obtain a logic for that situation. (shrink)

We investigate the use of coalgebra to represent quantum systems, thus providing a basis for the use of coalgebraic methods in quantum information and computation. Coalgebras allow the dynamics of repeated measurement to be captured, and provide mathematical tools such as final coalgebras, bisimulation and coalgebraic logic. However, the standard coalgebraic framework does not accommodate contravariance, and is too rigid to allow physical symmetries to be represented. We introduce a fibrational structure on coalgebras in which contravariance is represented by indexing. (...) We use this structure to give a universal semantics for quantum systems based on a final coalgebra construction. We characterize equality in this semantics as projective equivalence. We also define an analogous indexed structure for Chu spaces, and use this to obtain a novel categorical description of the category of Chu spaces. We use the indexed structures of Chu spaces and coalgebras over a common base to define a truncation functor from coalgebras to Chu spaces. This truncation functor is used to lift the full and faithful representation of the groupoid of physical symmetries on Hilbert spaces into Chu spaces, obtained in our previous work, to the coalgebraic semantics.

To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can (...) be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements. (shrink)

This paper proposes an account of accurate scientific representation in terms of techniques that produce data from a target phenomenon. I consider an approach to accurate representation that abstracts from such epistemic factors, justified by a thesis I call Ontic Priority. This holds that criteria for representational accuracy depend on a pre-established account of the nature of the relation between a model and its target phenomenon. I challenge Ontic Priority, drawing on the observation that many working scientists do not have (...) access to information allowing them to describe this relation between model and target or compare them accordingly. I critique the ability of an ontic-first approach to provide accuracy criteria in such cases and present historical support for an alternative according to which a model is accurate if and only if integrating the model into a theory of the data acquisition process yields well-fitting predictions of patterns in the data.

Dominant forms of contemporary big-data based digital citizen science do not question the institutional divide between qualified experts and lay-persons. In our paper, we turn to the historical case of a large-scale amateur project on biogeographical birdwatching in the late nineteenth and early twentieth century to show that networked amateur research can operate in a more autonomous mode. This mode depends on certain cultural values, the constitution of specific knowledge objects, and the design of self-governed infrastructures. We conclude by arguing (...) that the contemporary quest for autonomous citizen science is part of a broader discourse on the autonomy of scientific research in general. Just as the actors in our historical case positioned themselves against the elitism of gentlemen scientists, avant-garde groups of the twenty first century like biohackers and civic tech enthusiasts position themselves against the system of professional science—while “digital citizen science” remains to oscillate between claims for autonomy and realities of heteronomy, constantly reaffirming the classic lay-expert divide.
