In this study I propose an epistemological discussion of multiple spatio-temporal scales in neuroscience. Are such scales merely convenient levels of description of structure and function, or do they correspond to irreducible levels of brain organization? What criteria should we employ in order to reduce one level to another, or to identify levels that are not reducible to others? Should we think of these criteria as based on empirical and/or theoretical reasons? Beginning with an empirical criterion – the necessity of (...) different experimental methodologies for the measurement of different phenomena in the same system – I summarize spatial and temporal scales currently used in neuroscience and discuss the possibility of a more general theoretical criterion. I conclude that multiscaling should be recognized as a central concept in the epistemology of neuroscience. (shrink)
The NMDA receptor (NMDAR) channel has been proposed to function as a coincidence-detection mechanism for afferent and reentrant signals, supporting conscious perception, learning, and memory formation. In this paper we discuss the genesis of distorted perceptual states induced by subanesthetic doses of ketamine, a well-known NMDA antagonist. NMDAR blockage has been suggested to perturb perceptual processing in sensory cortex, and also to decrease GABAergic inhibition in limbic areas (leading to an increase in dopamine excitability). We propose that perceptual distortions and (...) hallucinations induced by ketamine blocking of NMDARs are generated by alternative signaling pathways, which include increase of excitability in frontal areas, and glutamate binding to AMPA in sensory cortex prompting Ca ++ entry through voltage-dependent calcium channels (VDCCs). This mechanism supports the thesis that glutamate binding to AMPA and NMDARs at sensory cortex mediates most normal perception, while binding to AMPA and activating VDCCs mediates some types of altered perceptual states. We suggest that Ca ++ metabolic activity in neurons at associative and sensory cortices is an important factor in the generation of both kinds of perceptual consciousness. (shrink)
In two studies, we used the Ethics Position Questionnaire (EPQ) to investigate the relationship between individual differences in moral philosophy, involvement in the animal rights movement, and attitudes toward the treatment of animals. In the first, 600 animal rights activists attending a national demonstration and 266 nonactivist college students were given the EPQ. Analysis of the returns from 157 activists and 198 students indicated that the activists were more likely than the students to hold an "absolutist" moral orientation (high idealism, (...) low relativism). In the second study, 169 students were given the EPQ with a scale designed to measure attitudes toward the treatment of animals. Multiple regression showed that gender and the EPQ dimension of idealism were related to attitudes toward animal use. (shrink)
Epistemic naturalism holds that the results or methodologies from the cognitive sciences are relevant to epistemology, and some have maintained that scientific methods are more compatible with externalist theories of justification than with internalist theories. But practically all discussions about naturalized epistemology are framed exclusively in terms of cognitive psychology, which is only one of the cognitive sciences. The question addressed in this essay is whether a commitment to naturalism really does favor externalism over internalism, and we offer reasons for (...) thinking that naturalism in epistemology is compatible with both internalist and externalist conceptions of justification. We also argue that there are some distinctively internalist aims that are currently being studied scientifically and these notions, and others, should be studied by scientific methods. (shrink)
The activism of institutional investors tends more and more toward the supervision and control of the behavior of the managers of big companies. In this article, we present a model based on the creation of an activism index that lets us evaluate such activism’s effect on the sensitivity of the investment policies of a company in the face of financial variables (such as cash flow and liquidity ratio) and market variables (ownership concentration and value creation index). To test our assertions, (...) we analyze firm-level data for United Kingdom (U.K.), Germany, France, Denmark, and Spain during the period 1995–2004. Our results point to a significant reduction in the sensitivity of company investment decisions in the face of these variables, especially relative to intangible capital, as a result of the neutralizing effect of activism on the high agency costs of free cash flow and on the information asymmetries of the market.

In Sein und Zeit, Heidegger claims that (1) das Man is an 'existential' i.e. a necessary feature of Dasein's Being; and (2) Dasein need not always exist in the mode of the Man-self, but can also be eigentlich, which I translate as 'self-owningly'. These apparently contradictory statements have prompted a debate between Hubert Dreyfus, who recommends abandoning (2), and Frederick Olafson, who favors jettisoning (1). I offer an interpretation of the structure of Dasein's Being compatible with both (1) and (2), (...) thus resolving the Dreyfus-Olafson debate. Central to this resolution is the distinction between das Man and the Man-self. Das Man is one of three existential 'horizons', or fields of possibilities; the other two horizons are the world and death. At any time, Dasein encounters entities in one of two basic modes: either by 'expressly seizing' possibilities of the horizon, or by occluding these possibilities. These modes are 'existentiell', i.e. features of Dasein's Being that are possible, but not essential. Self-ownership and the Man-self are the two basic existentiell modes of being oneself, i.e. projecting everyday possibilities of oneself appropriated from the horizon of das Man. What differentiates these two modes is the stance one takes to the possibility of death, the existential horizon of being oneself. (shrink)
To understand better why evidence of student cheating is often ignored, a national sample of psychology instructors was sampled for their opinions. The 127 respondents overwhelmingly agreed that dealing with instances of academic dishonesty was among the most onerous aspects of their profession. Respondents cited insufficient evidence that cheating has occurred as the most frequent reason for overlooking student behavior or writing that might be dishonest. A factor analysis revealed 4 other clusters of reasons as to why cheating may be (...) ignored. Emotional reasons included stress and lack of courage. Difficult reasons included the extensive time and effort required to deal with cheating students. Fear reasons included concern about retaliation or a legal challenge. Denial reasons included beliefs that cheating students would fail anyway and that the worst offenders do not get caught. The reasons why instances of academic dishonesty should be proactively confronted are presented. (shrink)
We present a new method for characterizing the interpretive possibilities generated by elliptical constructions in natural language. Unlike previous analyses, which postulate ambiguity of interpretation or derivation in the full clause source of the ellipsis, our analysis requires no such hidden ambiguity. Further, the analysis follows relatively directly from an abstract statement of the ellipsis interpretation problem. It predicts correctly a wide range of interactions between ellipsis and other semantic phenomena such as quantifier scope and bound anaphora. Finally, although the (...) analysis itself is stated nonprocedurally, it admits of a direct computational method for generating interpretations. (shrink)
Systematic semantic ambiguities result from the interaction of the two operations that are involved in resolving ellipsis in the presence of scoping elements such as quantifiers and intensional operators: scope determination for the scoping elements and resolution of the elided relation. A variety of problematic examples previously noted - by Sag, Hirschbüihler, Gawron and Peters, Harper, and others - all have to do with such interactions. In previous work, we showed how ellipsis resolution can be stated and solved in equational (...) terms. Furthermore, this equational analysis of ellipsis provides a uniform framework in which interactions between ellipsis resolution and scope determination can be captured. As a consequence, an account of the problematic examples follows directly from the equational method. The goal of this paper is merely to point out this pleasant aspect of the equational analysis, through its application to these cases. No new analytical methods or associated formalism are presented, with the exception of a straightforward extension of the equational method to intensional logic. (shrink)
Abstract Occupational stress in nursing has attracted considerable attention as a focus for research and as a consequence multiple objects of nurses' stress, or 'stressors', have been identified. This paper puts into question the dominant conceptual and methodological approach to occupational stress in nursing research by both foregrounding the notion of anxiety and juxtaposing it with the notion of 'stress'. It is argued that the notion of 'stress' and the domination of the questionnaire have produced a narrow reading of the (...) topic. Some of the literature on occupational stress/anxiety in nursing is reviewed and our analysis illustrates how the identified objects of stress have a tendency to multiply contingent on the number of studies undertaken. Thus definitive objects of nurses' stress remain elusive. We argue that a return to the notion of 'anxiety' and methodological approaches other than empirical ones can bring both depth and breadth to the consideration of occupational distress in nursing. Further, we argue that the object of 'anxiety' is unconscious, thus unknown, and given this, a more informative approach is to map nurses' response to anxiety, the discursive formations arising out of anxiety, rather than attempt to define those objects of anxiety.

The relationship between Lexical-Functional Grammar (LFG) functional structures (f-structures) for sentences and their semanticinterpretations can be formalized in linear logic in a way thatcorrectly explains the observed interactions between quantifier scopeambiguity, bound anaphora and intensionality.Our linear-logic formalization of the compositional properties ofquantifying expressions in natural language obviates the need forspecial mechanisms, such as Cooper storage, in representing thescoping possibilities of quantifying expressions. Instead, thesemantic contribution of a quantifier is recorded as a linear-logicformula whose use in a proof will establish the (...) scope of thequantifier. Different proofs can lead to different scopes. In eachcomplete proof, the properties of linear logic ensure thatquantifiers are properly scoped. (shrink)
In this paper we show the embedding of Hybrid Probabilistic Logic Programs into the rather general framework of Residuated Logic Programs, where the main results of (definite) logic programming are validly extrapolated, namely the extension of the immediate consequences operator of van Emden and Kowalski. The importance of this result is that for the first time a framework encompassing several quite distinct logic programming semantics is described, namely Generalized Annotated Logic Programs, Fuzzy Logic Programming, Hybrid Probabilistic Logic Programs, and Possibilistic (...) Logic Programming. Moreover, the embedding provides a more general semantical structure paving the way for defining paraconsistent probabilistic reasoning with a logic programming semantics. (shrink)
This study attempts to identify differences in the perceptions of top management (defined as CEOs, directors, and presidents) and employees (defined as middle and supervisory management) regarding (a) the effects of dependent care responsibilities on job performance, and (b) the extent of a firm's responsibility in providing support for those faced with caring needs concerning eldercare, childcare, substance abuse, and mental/physical handicaps.The results indicate that these two groups have significantly different perceptions of the effect of dependent care responsibilities on job (...) performance, and on the firm's responsibility in providing support for three types of dependent care.

Whitehead does not provide us with a systematic account of the various types of experience to which the word “memory” is applied. Nevertheless, he does provide us with a way of understanding the world, and living creatures who inhabit it, that places the discussion in a different context from the usual one: the diverse features of human experience that we call memory are developed forms of basic patterns of relationship that characterize all actual entities. I will first review the relevant (...) features of Whitehead's conceptuality, then contrast the resulting view with its usual formulation, and then speculate about some forms of memory in Whiteheadian categories.

Oliver Wendell Holmes, Jr. (1841-1935) is, arguably, the most important American jurist of the 20th century, and his essay The Path of the Law, first published in 1898, is the seminal work in American legal theory. In it, Holmes detailed his radical break with legal formalism and created the foundation for the leading contemporary schools of American legal thought. He was the dominant source of inspiration for the school of legal realism, and his insistence on a practical approach to law (...) and legal analysis laid the basis for the realists' later concentration upon the pragmatic and empirical aspects of law and legal procedures. This volume brings together some of the most distinguished legal scholars from the United States and Canada to examine competing understandings of The Path of the Law and its implications for contemporary American jurisprudence. For the reader's convenience, the essay is republished in an Appendix. (shrink)

This essay focuses on one aspect of the social thought of Martin Luther King, Jr.: his social ethics. Specifically, it poses the question whether, in what sense, and from what time it is correct to consider King a democratic socialist. The essay argues that King was in fact a democratic socialist and, contrary to the implications of some recent interpreters who have focused on transformation and radicalization in King's thought, that King's democratic socialism was rooted in his formative experience (...) of the black religious tradition and was manifested from his student days at Crozer Theological Seminary forward. The change that may be discerned in King's later years was only a refinement, not a transformation, of his basic orientation. (shrink)
Much attention has been devoted in recent years to the personal idealism of Martin Luther King, Jr. Among the major contributors to the scholarship in this area is Rufus Burrow, Jr., who places King firmly in the tradition of personal idealism, or personalism, while also uncovering the intellectual unease that made King both a deep and creative thinker and a committed and effective social activist.1 Clearly, Burrow's own sense of his role as a personalist informs his approach to the life (...) and thought of King. Although philosophical personalism figures prominently in Burrow's treatment of King in his writings, ethical and social personalism provides the primary theoretical framework for both Burrow's exploration of ..

This article describes the racial integration of Emory University and the subsequent creation of Pre-Start, an affirmative action program at Emory Law School from 1966 to 1972. It focuses on the initiative of the Dean of Emory Law School at the time, Ben F. Johnson, Jr. (1914-2006). Johnson played a number of leadership roles throughout his life, including successfully arguing a case before the United States Supreme Court while he was an Assistant Attorney General of Georgia, promoting legislation to create (...)Atlanta's subway system as a state senator, and representing Emory in its lawsuit to strike down the state statute that would have rescinded its tax exemption if it admitted African American students (Emory v. Nash, 218 Ga. 317 (Ga. 1962)). This account supplements my related article on Pre-Start, "'A Bulwark against Anarchy': Affirmative Action, Emory Law School, and Southern Self-Help" (SSRN abstract 1007006), providing more information about historical context generally, and particularly about Emory v. Nash. Johnson was ambitious for Emory as a whole, and particularly for the Law School, and he saw in segregation the single largest impediment to making Emory a nationally prominent research university. The story of Emory's integration, and Johnson's leadership, requires revision of the prevailing story of integration generally, and especially of universities. Integration at Emory came about because of the pressure that African Americans and their supporters created through the civil rights movement, but Emory administrators responded to such pressure more constructively than most (e.g., Universities of Alabama, Mississippi, Georgia, and Vanderbilt). Their actions provide an interesting case study in effective leadership during a period of significant moral and political conflict. (shrink)

The question of the relation of my work to that of Martin Luther King Jr. cannot be resolved with the theoretical tools Christopher Beem brings to the task. Stanley Fish has written that "those who detach King's words from the history that produced them erase the fact of that history from the slate, and they do so, paradoxically, in order to prevent that history from being truly and deeply altered." The vice of liberalism is not selfishness so much as (...) a forgetfulness that spreads like a blight from the habit of abstraction. Martin Luther King Jr. remembered his people, his savior, and his church, and he called the rest of us to share those memories. Therein lay his strength. (shrink)
This review essay examines H. TristramEngelhardt, Jr.'s The Foundations of Bioethics, a contemporary nonfeminist text in mainstream biomedical ethics. It focuses upon a central concept, Engelhardt's idea of the moral community and argues that the most serious problem in the book is its failure to take account of the political and social structures of moral communities, structures which deeply affect issues in biomedical ethics.

This is a expository and critical review of Arthur Schlesinger, Jr. 's last book, War and the American Presidency. The book collects and focuses recent writings of Arthur Schlesinger on the themes of its title. In its short Foreword and seven concise essays, the book aims to explore, in some contrast with the genre of “instant history,” the relationship between President George W. Bush’s Iraq adventure and the national past. This aim and the present work are deserving of wide attention, (...) both because of the contemporary need to deal with the extended war in Iraq and because Americans, in particular, need to attend to their own history, if we are to avoid past mistakes and make the best use of our ongoing political traditions and institutions. In order to know better where we might go in the future, we need an adequate picture of where we have been in the past. Schlesinger invites us to debate the war, the Presidency, and their relation to the American past. (shrink)
