Within psychology, at least two research communities study spatial cognition. One community studies systematic errors in spatial memory and judgement, accounting for them as a consequence of and clue to normal perceptual and cognitive processing. The other community studies navigation in real space, isolating the contributions of various sensory cues and sensori- motor systems to successful navigation. The former group emphasizes error, the latter, selective mechanisms, environmental or evolutionary, that produce fine-tuned correct responses. How can these approaches be reconciled and (...) integrated? First, by showing why errors are impervious to selective pressures. The schematization that leads to errors is a natural consequence of normal perceptual and cognitive processes; it is inherent to the construction of mental spaces and to using them to make judgments in limited capacity working memory. Selection can act on particular instances of errors, yet it is not clear that selection can act on the general mechanisms that produce them. Next, in the wild, there are a variety of correctives. Finally, closer examination of navigation in the wild shows systematic errors, for example, over-shooting in dead reckoning across species. Here, too, environments may provide correctives, specifically, landmarks. General cognitive mechanisms generate general solutions. The errors inevitably produced may be reduced by local specific sensori-motor couplings as well as local environmental cues. Navigation, and other behaviors as well, are a consequence of both.

Peer interaction has been found to be conducive to learning in many settings. Knowledge co-construction has been proposed as one explanatory mechanism. However, KCC is a theoretical construct that is too abstract to guide the development of instructional software that can support peer interaction. In this study, we present an extensive analysis of a corpus of peer dialogs that we collected in the domain of introductory Computer Science. We show that the notion of task initiative shifts correlates with both KCC (...) and learning. Speakers take task initiative when they contribute new content that advances problem solving and that is not invited by their partner; if initiative shifts between the partners, it indicates they both contribute to problem solving. We found that task initiative shifts occur more frequently within KCC episodes than outside. In addition, task initiative shifts within KCC episodes correlate with learning for low pre-testers, and total task initiative shifts correlate with learning for high pre-testers. As recognizing task initiative shifts does not require as much deep knowledge as recognizing KCC, task initiative shifts as an indicator of productive collaboration are potentially easier to model in instructional software that simulates a peer.

No consensus yet exists on how to handle incidental fnd-ings in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are fndings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers (...) have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed. (shrink)

The pioneering anthology Home Girls features writings by Black feminist and lesbian activists on topics both provocative and profound. Since its initial publication in 1983, it has become an essential text on Black women's lives and writings. This edition features an updated list of contributor biographies and an all-new preface that provides a fresh assessment of how Black women's lives have changed-or not-since the book was first published. Contributors are Tania Abdulahad, Donna Allegra, Barbara A. Banks, Becky Birtha, Julie (...) Carter, Cenen, Cheryl Clarke, Michelle Cliff, Michelle T. Clinton, Willie M.

Barbara Jordan (1936–1996), a formidable politician, won election to the Texas Senate (1966) and to the US Congress (1972). She became one of the most celebrated African‐American politicians of the twentieth century, acclaimed both by white and black. Jordan was a voluntarist, viewing individuals as able to change the world through their own actions. She was committed to the American dream of inclusion, and also to the importance of positive ties to elites; to coping with the ‘world (...) as it is’, to the futility of confrontation, and also to changing and influencing the attitudes of men at the top. Jordan opposed civil disobedience, nonviolent or not. Yet she admired symbols of defiance like Malcolm X and Mohammed Ali. A highly public figure, she was also exceptionally self‐repressed. Critics likened her to the conservative Booker Washington, yet she was a staunch defender of voting rights and a radical integrationist. (shrink)

Despite emerging study of business initiatives that attempt to support local peace and development, we still have significant knowledge gaps on their effectiveness and efficiency. This article builds theory on business engagements for peace through exploration of the Footprints for Peace (FOP) peacebuilding project by the Federación Nacional de Cafeteros de Colombia (FNC). FOP was a business-peace initiative that attempted to improve the lives of vulnerable populations in conflict-affected regions. Through 70 stakeholder interviews, we show how FOP operationalized local peace (...) and development in four conflict-affected departments of Colombia, and examine FNC’s motivations for and effectiveness of its peacebuilding activities. Our main finding is that FOP’s success supported several existing theories on business engagement in peace both in terms of peacebuilding by business and for local economic and societal development, providing evidence in support of development–business collaborations and local peacebuilding by business under certain targeted circumstances. We relate these findings to existing literature, highlighting where existing business-peace theory is supported, where FOP challenged assumptions, and where it illuminated new research gaps. These findings serve to take business-peace theory forward and improve our understandings of what can constitute success for business-peace initiatives in Colombia and possibly other conflict-affected regions.

Strawson (1994) and Peacocke (1992) introduced thought experiments that show that it seems intuitive that there is, in some way, an experiential character to mental events of understanding. Some (e.g., Siewert 1998, 2011; Pitt 2004) try to explain these intuitions by saying that just as we have, say, headache experiences and visual experiences of blueness, so too we have experiences of understanding. Others (e.g., Prinz 2006, 2011; Tye 1996) propose that these intuitions can be explained without positing experiences of understanding. (...) Call this the debate between Realism and Anti-Realism about experiences of understanding. This paper aims to advance that debate in two ways. In the first half, I develop more precise characterizations of what Realists and Anti-Realists propose. In the second half, I distinguish the four most plausible versions of Anti-Realism and argue that Realism better explains the target intuition than any of them does. (shrink)

The phrase "natural kind term" has come into the linguistic and philosophical literature in connection with well-known work of Kripke (1972) and Putnam (1970, 1975a). I use that phrase here in the sense it has acquired from those and subseqnent works on related topics. This is not the transparent sense of the phrase. That is, if I am right in what follows there are words for kinds of things existing in nature which are not natural kind terms in the current (...) sense - e.g. planet, woman, and weed. I use the term "nondescriptional", following Salmon (1981), to mean "lacking a Fregean sense", where a Fregean sense is taken to be a property or group of properties semantically associated with an expression which determines its denotation. I hope that the term "nondescriptional" will be clarified in subsequent discussion, but perhaps a few words about it and its opposite, "descriptional", would be useful here. These terms (as Salmon notes (p.15, n. 11)) should be taken as technical terms. The idea is that descriptional words, of which bachelor is the overwhelmingly favorite example, express a semantic content, or sense, which is what mediates their denotation. Entities fall in their denotation in virtue of possessing the property or properties expressed as their sense. (It is not necessary, however, that this sense be as easily paraphrasable with descriptive synonyms as it is typically held to be in the case of bachelor, or even that it be paraphrasable at all.) In the case of nondescriptional words there is no Fregean sense to mediate the link between word and object. Hence such terms are described by what Salmon, following Kaplan, calls "the theory of direct reference". What it is that does associate such terms with their denotations is another question which will be touched on briefly at the end. I have several aims in this paper. The first is to defend a conservative position on nondescriptionality. I will argue that relatively few natural language words have this property. My other aims are primarily clarificatory. Among the issues I would like to clarify are those connected with the determination of this property and flae explanation of why it exists, its relationship with other properties such as rigid designation and essentiality, and its significance for lexical semantics. The organization of the paper is as follows. The first section identifies the position taken here on the question of which expressions are nondescriptional and provides a general defense of it. The second section is a critical examination of criteria associated with nondescriptionality. In the third section provide further defense for the conservative position, and in the fourth section we turn to related issues in lexical semantics. (shrink)

Szabó follows Heim in viewing familiarity, rather than uniqueness, as the essence of the definite article, but attempts to derive both familiarity and uniqueness implications pragmatically, assigning a single semantic interpretation to both the definite and indefinite articles. I argue that if there is no semantic distinction between the articles, then there is no way to derive these differences between them pragmatically.

Chemical kinds are generally treated as having timelessly fixed identities. Biological kinds are generally treated as evolved and/or evolving entities. So what kind of kind is a biochemical kind? This article defends the thesis that biochemical molecules are clustered chemical kinds, some of which—namely, evolutionarily conserved units—are also biological kinds. On this thesis, a number of difficulties that have recently occupied philosophers concerned with proteins and kinds are shown to be either resolved or dissolved. 1 Introduction2 Conflicting Intuitions about Kinds (...) of Proteins3 Against Permissive Pluralism4 Against Nominalism, Toward a Duality of Kinds5 Biological Kinds, Chemical Kinds, and Their Relations6 Implications for Biological Individuals7 Implications for Monism and Scientific Practice.

What does everyone in the modern world need to know? Renowned psychologist Jordan B. Peterson's answer to this most difficult of questions uniquely combines the hard-won truths of ancient tradition with the stunning revelations of cutting-edge scientific research. Humorous, surprising and informative, Dr. Peterson tells us why skateboarding boys and girls must be left alone, what terrible fate awaits those who criticize too easily, and why you should always pet a cat when you meet one on the street. What (...) does the nervous system of the lowly lobster have to tell us about standing up straight (with our shoulders back) and about success in life? Why did ancient Egyptians worship the capacity to pay careful attention as the highest of gods? What dreadful paths do people tread when they become resentful, arrogant and vengeful? Dr. Peterson journeys broadly, discussing discipline, freedom, adventure and responsibility, distilling the world's wisdom into 12 practical and profound rules for life. [This book] shatters the modern commonplaces of science, faith and human nature, while transforming and ennobling the mind and spirit of its readers. (shrink)

This article argues that every performance of habit‐driven action requires attention. I begin by revisiting the conception of habit‐driven actions as reducible to automatically performed responses to stimuli. On this conception, habitual actions are a counterexample to Wayne Wu's action‐centered theory of attention. Using the biased competition model of attention, and building on findings from affective cognitive neuroscience, I challenge this position. I claim that the performance of a habitual action requires experiential history to be exerting an influence that is (...) best understood as implicit selection‐biasing. It follows from this that habit‐driven action is compatible with Wu's theory. (shrink)

Personalized genomics companies (PG; also called ‘direct-to-consumer genetics’) are businesses marketing genetic testing to consumers over the Internet. While much has been written about these new businesses, little attention has been given to their roles in science communication. This paper provides an analysis of the gene concept presented to customers and the relation between the information given and the science behind PG. Two quite different gene concepts are present in company rhetoric, but only one features in the science. To explain (...) this, we must appreciate the delicate tension between PG, academic science, public expectation, and market forces. (shrink)

The ‘black box problem’ is a long-standing talking point in debates about artificial intelligence. This is a significant point of tension between ethicists, programmers, clinicians and anyone else working on developing AI for healthcare applications. However, the precise definition of these systems are often left undefined, vague, unclear or are assumed to be standardised within AI circles. This leads to situations where individuals working on AI talk over each other and has been invoked in numerous debates between opaque and explainable (...) systems. This paper proposes a coherent and clear definition for the black box problem to assist in future discussions about AI in healthcare. This is accomplished by synthesising various definitions in the literature and examining several criteria that can be extrapolated from these definitions. There are no data in this work. (shrink)

Rules are meant to apply equally to all within their jurisdiction. However, some rules are frequently broken without consequence for most. These rules are only occasionally enforced, often at the discretion of a third-party observer. We propose that these rules—whose violations are frequent, and enforcement is rare—constitute a unique subclass of explicitly codified rules, which we call ‘phantom rules’ (e.g., proscribing jaywalking). Their apparent punishability is ambiguous and particularly susceptible to third-party motives. Across six experiments, (N = 1440) we validated (...) the existence of phantom rules and found evidence for their motivated enforcement. First, people played a modified Dictator Game with a novel frequently broken and rarely enforced rule (i.e., a phantom rule). People enforced this rule more often when the “dictator” was selfish (vs. fair) even though the rule only proscribed fractional offers (not selfishness). Then we turned to third person judgments of the U.S. legal system. We found these violations are recognizable to participants as both illegal and commonplace (Experiment 2), differentiable from violations of prototypical laws (Experiments 3) and enforced in a motivated way (Experiments 4a and 4b). Phantom rule violations (but not prototypical legal violations) are seen as more justifiably punished when the rule violator has also violated a social norm (vs. rule violation alone)—unless the motivation to punish has been satiated (Experiment 5). Phantom rules are frequently broken, codified rules. Consequently, their apparent punishability is ambiguous, and their enforcement is particularly susceptible to third party motives. (shrink)

In this paper I argue that Pereboom’s empirical objection to agent causation fails to undermine the most plausible version of agent-causal libertarianism. This is significant because Pereboom concedes that such libertarianism is conceptually coherent and only falls to empirical considerations. To substantiate these claims I outline Pereboom’s taxonomy of agent-causal views, develop the strongest version of his empirical objections, and then show that this objection fails to undermine what I consider the most plausible view of agent-causal libertarianism, namely, reconciliatory integrationist (...) agent-causalism. I then strengthen my criticism of Pereboom by responding to three objections to my view. I show that these objections, though initially challenging, fail to undermine my argument. I therefore conclude that, to this extent, agent-causal views remain a viable option in the contemporary free will debate. (shrink)

Several recent criticisms of the somatic marker hypothesis (SMH) identify multiple ambiguities in the way it has been formulated by its chief proponents. Here we provide evidence that this hypothesis has also been interpreted in various different ways by the scientific community. Our diagnosis of this problem is that SMH lacks an adequate computational-level account of practical decision making. Such an account is necessary for drawing meaningful links between neurological- and psychological-level data. The paper concludes by providing a simple, five-step (...) model of practical decision making. Recasting SMH in terms of this model generates more precise and empirically tractable computational-level hypotheses about the various ways that somatic markers might influence practical decisions.

Roy Sorensen introduced the concept of an epistemic blindspot in the 1980s. A proposition is an epistemic blindspot for some individual at some time if and only if that proposition is consistent but unknowable by that individual at that time. In the first half of this paper, I extend Sorensen work on blindspots by arguing that there exist blindspots that essentially involve hopes. In the second half, I show how such blindspots can contribute to and impair different pursuits of self-understanding. (...) My arguments throughout this paper draw on Luc Bovens’s account of hope.

This Element examines Kant's innovative account of labour in his political philosophy and develops an intersectional analysis of Kant. By demonstrating that Kant's analysis of slavery, citizenship, and sex developed in inter-linked ways over several decades, culminating in his development of a 'trichotomy' of Right, the author shows that Kant's normative account of independence is configured through his theory of labour, and is continuous with his anthropological accounts of race and gender, providing a systemic justification for the dependency of women (...) and non-whites embedded in his philosophy of right. By examining Kant's arguments about slavery as intertwined with his account of domestic labour, the author argues that his ultimate rejection of slavery may owe more to his changing conceptualization of labour than to his theory of race, and that his final arguments against slavery rehearse strategies for embedding intersectional patterns of domestic dependence in his account of the rightful state.

Redish et al. provide a significant advance in our understanding of addiction by showing that the various addictive processes are in fact all decision-making processes and each may undergird addiction. We propose means for identifying more central addiction processes. This recognition of the complexity of addiction followed by identification of more central processes would help guide the development of prevention and treatment.

25 medical historians born between 1800 and 1900 have been selected, mainly by citation frequency, for a study in comparative biography. They originated in Germany, U.S.A., U.K. France, Switzerland, Italy, and Austria. A number of them were active in two countries due to emigration from fascist Europe in the 1930s. All were MDs except for one historian. Most of them showed an interest in the history of medicine early in life, some only between age 40–50. Their motivations were quite varied. (...) Most of them made their living with clinical practice, at least initially. Those ten who attained a chair in the history of medicine did so usually between age 41 and 56. Our selection of medical historians active between 1825 and 1975 is very heterogeneous, much more so than in the final decades of the 20th century. (shrink)

Are demands for equality motivated by envy? Nietzsche, Freud, Hayek, and Nozick all thought so. Call this the Envy Objection. For egalitarians, the Envy Objection is meant to sting. Many egalitarians have tried to evade the Envy Objection.. But should egalitarians be worried about envy? In this paper, I argue that egalitarians should stop worrying and learn to love envy. I argue that the persistent unwillingness to embrace the Envy Objection is rooted in a common misunderstanding of the nature of (...) the charge, what it reveals, and what can be said in response to it. I develop what Bernard Williams might call a vindicatory genealogy of envy, thereby allowing us to see that envy, rather than undermining egalitarian intuitions, can in fact play a distinct justificatory role (when it is fitting), which undermines the Envy Objection.

Association between sister chromatids is essential for their attachment and segregation to opposite poles of the spindle in mitosis and meiosis II. Sister‐chromatid cohesion is also likely to be involved in linking homologous chromosomes together in meiosis I. Cytological observations provide evidence that attachment between sister chromatids is different in meiosis and mitosis and suggest that cohesion between the chromatid arms may differ mechanistically from that at the centromere. The physical nature of cohesion is addressed, and proteins that are candidates (...) for holding sister chromatids together are discussed. Dissolution of sister‐chromatid cohesion must be regulated precisely, and potential mechanisms to release cohesion are presented. (shrink)

To systematically answer the generalized Kretschmann objection, I propose a mean to make operational a criterion widely recognized as allowing one to decide whether the gauge symmetry of a theory is artificial or substantial. My proposition is based on the dressing field method of gauge symmetry reduction, a new simple tool from mathematical physics. This general scheme allows one in particular to straightforwardly argue that the notion of spontaneous symmetry breaking is superfluous to the empirical success of the electroweak theory. (...) Important questions regarding the context of justification of the theory then arise. (shrink)
