There is a major debate as to whether there are non-causal mathematical explanations of physical facts that show how the facts under question arise from a degree of mathematical necessity considered stronger than that of contingent causal laws. We focus on Marc Lange’s account of distinctively mathematical explanations to argue that purported mathematical explanations are essentially causal explanations in disguise and are no different from ordinary applications of mathematics. This is because these explanations work not by appealing to what the (...) world must be like as a matter of mathematical necessity but by appealing to various contingent causal facts. (shrink)

This study tests an integrative model of corporate political action, the filter model, based on the behavioral theory of the firm. The filter model posits that external political, economic, and industry environments are mediated by organizational structures and resources to affect a firm’s political actions. The authors rate the filter model’s predictive power against that of an economic-based direct-effects model by examining the efforts of about 1,100 U.S.-domiciled manufacturing firms to influence trade policy. LISREL analysis demonstrates that the integrative filter (...) model provides a superior explanation of corporate political action. (shrink)

Ethical consumption is on the rise, however little is known about the degree and the implications of the sometime conflicting sets of values held by the broad category of consumers who report consuming ethically. This paper explores convergence and divergence of ethical consumption values through a study of organic, fair trade, and local food consumers in Colorado. Using survey and focus group results, we first examine demographic and attitudinal correlates of ethical consumption. We then report evidence that while many organic, (...) fair trade, and local food consumers converge around similar values, some Colorado consumers support only local food, while opposing the consumption of organic and fair trade products. Next, we investigate how ethical consumers who converge and diverge frame their commitment to consuming ethically. The discussion and conclusion suggest that community development planners of projects that focus on ethical consumption will need to successfully traverse issues stemming from convergence and divergence to enjoy long-term sustained success.

Generation Y is a cohort of the population larger than the baby boom generation. Consisting of approximately 80 million people born between 1981 and 2000, Generation Y is the most recent cohort to enter the workforce. Workplaces are being redefined and organizations are being pressed to adapt as this new wave of workers is infused into business environments. One critical aspect of this phenomenon not receiving sufficient research attention is the impact of Gen Y ethical beliefs and ethical conduct in (...) workplace contexts. It is widely accepted that distinct generational experiences shape ethical ideologies and ethical ideologies in turn affect the way people function in the workplace. Thus, Gen Y’s unique cohort experiences are likely to shape their ethical ideologies and consequent workplace judgments and actions. In this article, we examine Gen Y’s ethical ideology and study its impact on workplace functioning regarding leadership style, teamwork, and judgments about ethical violations. Our analyses indicate that Gen Y’ers tend toward situationalism (high idealism and high relativism), and their socially connected orientation produces more lenient judgments of collaborative vs. unilateral ethical violations. However, Gen Y’ers do exhibit individual variation. Relativist Gen Y’ers are more tolerant of ethical violations, whereas, Gen Y Idealists are less tolerant of ethical violations. High Idealists also show stronger teamwork and leadership characteristics. In addition, Gen Y’ers possessing servant leader traits exhibit incrementally better teamwork, and greater perceived unacceptability of ethical violations. We conclude by discussing implications of these findings for managing ethical climates and conduct. (shrink)

Recent research suggests that individuals with relatively weak global precedence (i.e., a smaller propensity to view visual stimuli in a configural manner) show a reduced face inversion effect (FIE). Coupled with such findings, a number of recent studies have demonstrated links between an advantage for feature-based processing and the presentation of traits associated with autism among the general population. The present study sought to bridge these findings by investigating whether a relationship exists between the possession of autism-associated traits (i.e., as (...) indicated by individuals’“autism quotient” [(AQ) and the size of the FIE. Participants completed an on-line study in which the AQ was measured prior to a standard face recognition task where half of the faces were inverted at test. The results confirmed that higher AQ levels were predictive of smaller FIEs. Implications for a common underlying factor relating to processing orientation are discussed. (shrink)

The case of Ashley X involved a young girl with profound and permanent developmental disability who underwent growth attenuation using high-dose estrogen, a hysterectomy, and surgical removal of her breast buds. Many individuals and groups have been critical of the decisions made by Ashley's parents, physicians, and the hospital ethics committee that supported the decision. While some of the opposition has been grounded in distorted facts and misunderstandings, others have raised important concerns. The purpose of this paper is to provide (...) a brief review of the case and the issues it raised, then address 25 distinct substantive arguments that have been proposed as reasons that Ashley's treatment might be unethical. We conclude that while some important concerns have been raised, the weight of these concerns is not sufficient to consider the interventions used in Ashley's case to be contrary to her best interests, nor are they sufficient to preclude similar use of these interventions in the future for carefully selected patients who might also benefit from them.

Policy-makers must allocate scarce resources to support constituents’ health needs. This requires policy-makers to be able to evaluate health states and allocate resources according to some principle of allocation. The most prominent approach to evaluating health states is to appeal to the strength of people’s preferences to avoid occupying them, which we refer to as decision utility metrics. Another approach, experienced utility metrics, evaluates health states based on their hedonic quality. In this article, we argue that although decision utility metrics (...) face a number of significant problems, the appropriate response to these problems is not to replace them with experienced utility metrics. Rather, decision utility metrics should be employed in conjunction with experienced utility metrics. Specifically, respondents to decision utility surveys should be provided with the results of experienced utility metrics in an effort to make their decisions better informed and more robust to the deficiencies of decision utility metrics. Ultimately, this approach would improve quality-adjusted life year calculations and enhance the decision-making of policy-makers in allocating resources to support constituents’ health needs.

Various types of continuity for preference relations on a metric space are examined constructively. In particular, necessary and sufficient conditions are given for an order-dense, strongly extensional preference relation on a complete metric space to be continuous. It is also shown, in the spirit of constructive reverse mathematics, that the continuity of sequentially continuous, order-dense preference relations on complete, separable metric spaces is connected to Ishihara's principleBD-ℕ, and therefore is not provable within Bishop-style constructive mathematics alone.

In this article, I make the case for the continued relevance of Plato’s Timaeus. I begin by sketching Allan Bloom’s picture of the natural sciences today in The Closing of the American Mind, according to which the natural sciences are, objectionably, increasingly specialized and have ejected humans qua humans from their purview. I argue that Plato’s Timaeus, despite the falsity of virtually all of its scientific claims, provides a model for how we can pursue scientific questions in a comprehensive way (...) that stresses their connections to other disciplines, including the humanities, and that puts humanity qua humanity back in the picture. I then argue that being led by Plato’s philosophy to return humanity conceptually to the natural world can improve our thinking regarding climate change and other important environmental crises.

Psychometric properties of Attentional Control Scale: The preliminary study on a Polish sample The presented study was focused primarily on a psychometric analysis of the Attentional Control Scale, but they also enhanced the understanding of the role of effortful attentional skills in determining the individual well-being, general adaptation or emotional disorders. The analyses included basic item and scale descriptions as well as convergent and discriminant validity. 218 Polish undergraduate students completed the battery of the self-report techniques and two paper —pencil (...) attentional tests. Data revealed a unidimensional of a 20-item ACS. It can be used validly to assess long-term individual differences in attentional skills related to the voluntary executive functions. The analysis of content, internal and construct validity as well as reliability provided evidence of the scale's significant convergent and discriminant validity when correlated with attentional tests and other personality techniques. We found strong, systematic relations between the attentional control and selected measures of temperament, arousal, emotionality, and motivation. The results allow assuming that good attentional control, may protect individuals from the emotional disorders by regulating perceptual, conceptual, and response processing. (shrink)

The partial ordering of Medvedev reducibility restricted to the family of Π0 1 classes is shown to be dense. For two disjoint computably enumerable sets, the class of separating sets is an important example of a Π0 1 class, which we call a ``c.e. separating class''. We show that there are no non-trivial meets for c.e. separating classes, but that the density theorem holds in the sublattice generated by the c.e. separating classes.

Abstract.The partial ordering of Medvedev reducibility restricted to the family of Π01 classes is shown to be dense. For two disjoint computably enumerable sets, the class of separating sets is an important example of a Π01 class, which we call a ``c.e. separating class''. We show that there are no non-trivial meets for c.e. separating classes, but that the density theorem holds in the sublattice generated by the c.e. separating classes.

Berkeley, Hume, and Russell rejected the traditional analysis of substances in terms of qualities which are supported by an "unknowable substratum." To them the proper alternative seemed obvious. Eliminate the substratum in which qualities are alleged to inhere, leaving a bundle of coexisting qualities--a view that we may call the Bundle Theory or BT. But by rejecting only part of the traditional substratum theory instead of replacing it entirely, Bundle Theories perpetuate certain confusions which are found in the Substratum Doctrine. (...) I examine two major types of BT developed by Russell and by G. F. Stout with the intention of showing that (1) the seemingly innocuous concept of "a quality" employed by these versions cannot be used to state their theories coherently, and (2) the fatal problems that the BT encounters point to a more satisfactory and interesting alternative to both the Substratum Doctrine and the BT. This is a view that I call the Qualified Particulars Theory. In a final section I draw morals from this discussion that apply to the analogous Humean view that a mind is a "bundle of perceptions and sensations.". (shrink)

This paper is a continuation of the authors' work , where the main problem considered was whether a given recursive structure is recursively isomorphic to a polynomial-time structure. In that paper, a recursive Abelian group was constructed which is not recursively isomorphic to any polynomial-time Abelian group. We now show that if every element of a recursive Abelian group has finite order, then the group is recursively isomorphic to a polynomial-time group. Furthermore, if the orders are bounded, then the group (...) is recursively isomorphic to a polynomial-time group with universe A being the set of tally representations of natural numbers Tal = s{;1s};* or the set of binary representations of the natural numbers Bin. We also construct a recursive Abelian group with all elements of finite order but which has elements of arbitrary large finite order which is not isomorphic to any polynomial-time group with universe Tal or Bin. Similar results are obtained for structures , where f is a permutation on the set A. (shrink)

We argue that (1) a purported example of an infinite inference we humans can actually perform admits a faithful, finitary description, and (2) infinite inference contravenes any view which does not grant our minds uncomputable powers. These arguments block the strategy, dating back to Carnap's Logical Syntax of Language, of using infinitary inference rules to secure the determinacy of arithmetical truth on conventionalist grounds.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

An important source of doubt about our knowledge of the "external world" is the thought that all of our sensory experience could be delusive without our realizing it. Such wholesale questioning of the deliverances of all forms of perception seems to leave no resources for successfully justifying our belief in the existence of an objective world beyond our subjective experiences. I argue that there is there is a fatal flaw in the very expression of philosophical doubt about the "external world." (...) Therefore, no such justification is necessary. The feature of skepticism which I believe renders it vulnerable is the assumption that each of us has a right to be certain of his own existence as a subject of conscious experience even in the face of comprehensive doubt about our empirical beliefs.

A Π01 class is an effectively closed set of reals. We study properties of these classes determined by cardinality, measure and category as well as by the complexity of the members of a class P. Given an effective enumeration {Pe:e < ω} of the Π01 classes, the index set I for a certain property is the set of indices e such that Pe has the property. For example, the index set of binary Π01 classes of positive measure is Σ02 complete. (...) Various notions of boundedness are discussed and classified. For example, the index set of the recursively bounded classes is Σ03 complete and the index set of the recursively bounded classes which have infinitely many recursive members is Π04 complete. Consideration of the Cantor-Bendixson derivative leads to index sets in the transfinite levels of the hyperarithmetic hierarchy. (shrink)

The central problem considered in this paper is whether a given recursive structure is recursively isomorphic to a polynomial-time structure. Positive results are obtained for all relational structures, for all Boolean algebras and for the natural numbers with addition, multiplication and the unary function 2x. Counterexamples are constructed for recursive structures with one unary function and for Abelian groups and also for relational structures when the universe of the structure is fixed. Results are also given which distinguish primitive recursive structures, (...) exponential-time structures and structures with honest witnesses. (shrink)

Several diagrams and tables from review articles during the Ox-Phos Controversy serve as an occasion to assess the nature of competition in models of theory choice in science. Many models follow "Super-Bowl" principles of polar, either-or, winner-take-all competition. A significant alternative highlighted by this episode, however, is the differentiation of domains. Incommensurability and the partial divergence of overlapping domains serve both as signals and context for shifting frameworks of competition. Appropriate strategies may thus help researchers diagnose the status of competition (...) and shape their research accordingly. (shrink)

In this engaging book, Douglas Anderson begins with the assumption that philosophy—the Greek love of wisdom—is alive and well in American culture. At the same time, professional philosophy remains relatively invisible. Anderson traverses American life to find places in the wider culture where professional philosophy in the distinctively American tradition can strike up a conversation. How might American philosophers talk to us about our religious experience, or political engagement, or literature—or even, popular music? Anderson’s second aim is to find (...) places where philosophy happens in nonprofessional guises—cultural places such as country music, rock’n roll, and Beat literature. He not only enlarges the tradition of American philosophers such as John Dewey and William James by examining lesser-known figures such as Henry Bugbee and Thomas Davidson, but finds the theme and ideas of American philosophy in some unexpected places, such as the music of Hank Williams, Tammy Wynette, and Bruce Springsteen, and the writingsof Jack Kerouac.The idea of “philosophy Americana” trades on the emergent genre of “music Americana,” rooted in traditional themes and styles yet engaging our present experiences. The music is “popular” but not thoroughly driven by economic considerations, and Anderson seeks out an analogous role for philosophical practice, where philosophy and popular culture are co-adventurers in the life of ideas. Philosophy Americana takes seriously Emerson’s quest for the extraordinary in the ordinary and James’s belief that popular philosophy can still be philosophy. (shrink)

We describe here an interdisciplinary lab science course for non-majors using the history of science as a curricular guide. Our experience with diverse instructors underscores the importance of the teachers and classroom dynamics, beyond the curriculum. Moreover, the institutional political context is central: are courses for non-majors valued and is support given to instructors to innovate? Two sample projects are profiled.

We develop a theory of LOGSPACE structures and apply it to construct a number of examples of Abelian Groups which have LOGSPACE presentations. We show that all computable torsion Abelian groups have LOGSPACE presentations and we show that the groups ${\mathbb {Z}, Z(p^{\infty})}$ , and the additive group of the rationals have LOGSPACE presentations over a standard universe such as the tally representation and the binary representation of the natural numbers. We also study the effective categoricity of such groups. For (...) example, we give conditions are given under which two isomorphic LOGSPACE structures will have a linear space isomorphism. (shrink)

The purpose of this study was to identify general characteristics attributed to ethical business cultures by executives from a variety of industries. Our research identified five clusters of characteristics: Mission- and Values-Driven, Stakeholder Balance, Leadership Effectiveness, Process Integrity, and Long-term Perspective. We propose that these characteristics be used as a foundation of a comprehensive model that can be engaged to influence operational practices in creating and sustaining an ethical business culture.

Building on their important findings in The Source of the River, the authors now probe even more deeply into minority underachievement at the college level. Taming the River examines the academic and social dynamics of different ethnic groups during the first two years of college. Focusing on racial differences in academic performance, the book identifies the causes of students' divergent grades and levels of personal satisfaction with their institutions. Using survey data collected from twenty-eight selective colleges and universities, Taming the (...) River considers all facets of student life, including who students date, what fields they major in, which sports they play, and how they perceive their own social and economic backgrounds. The book explores how black and Latino students experience pressures stemming from campus racial climate and "stereotype threat"--when students underperform because of anxieties tied to existing negative stereotypes. Describing the relationship between grade performance and stereotype threat, the book shows how this link is reinforced by institutional practices of affirmative action. The authors also indicate that when certain variables are controlled, minority students earn the same grades, express the same college satisfaction, and remain in school at the same rates as white students. A powerful look at how educational policies unfold in America's universities, Taming the River sheds light on the social and racial factors influencing student success. (shrink)

This investigation joins recent research on problems with ambiguity in two fields, argumentation and computing. In argumentation, there is a concern with fallacies arising from ambiguity, including equivocation and amphiboly. In computing, the development of agent communication languages is based on conversation policies that make it possible to have information exchanges on the internet, as well as other forms of dialogue like persuasion and negotiation, in which ambiguity is a problem. Because it is not possible to sharply differentiate between problems (...) arising from ambiguity and those arising from vagueness, obscurity and indeterminacy, some study of the latter is included. The semantic web is based on what are called ontologies, or systems of classification of concepts, shown to be useful tools for dealing with these problems. (shrink)

The traditional analysis of substances in terms of qualities which are supported by a "substratum" was rejected by conscientious empiricists like Berkeley, Hume and Russell on the grounds that only qualities, not the substratum, could be experienced. To these philosophers the proper alternative seemed obvious. One simply eliminates the "unknowable" element in which qualities are alleged to inhere. In Russell's words, "What would commonly be called a 'thing' is nothing but a bundle of coexisting qualities such as redness, hardness, etc."' (...) But this empiricist formula has difficulties of its own, and some philosophers have attempted to develop other views of particulars which avoid the errors of the Substratum Doctrine on the one hand and the Bundle-of¬Qualities Theory on the other.2 Discussions of what this third alternative might be have generally approached the question through an examination of the epistemologically suspect concepts of a substratum and its close relative, the concept of a "bare particular". The concept of a quality of something, because it seemingly presents no epistemological difficulties, has attracted much less critical attention. This imbalance in critical interest is unfortunate, however, for a close scrutiny of this latter concept, especially in its role as the key element in the "bundle" analysis of particulars, throws a great deal of light on the relation between particulars and their attributes. -/- .

Important examples of $\Pi^0_1$ classes of functions $f \in {}^\omega\omega$ are the classes of sets (elements of ω 2) which separate a given pair of disjoint r.e. sets: ${\mathsf S}_2(A_0, A_1) := \{f \in{}^\omega2 : (\forall i < 2)(\forall x \in A_i)f(x) \neq i\}$ . A wider class consists of the classes of functions f ∈ ω k which in a generalized sense separate a k-tuple of r.e. sets (not necessarily pairwise disjoint) for each k ∈ ω: ${\mathsf S}_k(A_0,\ldots,A_k-1) := (...) \{f \in {}^\omega k : (\forall i < k) (\forall x \in A_i) f(x) \neq i\}$ . We study the structure of the Medvedev degrees of such classes and show that the set of degrees realized depends strongly on both k and the extent to which the r.e. sets intersect. Let ${\mathcal S}^m_k$ denote the Medvedev degrees of those ${\mathsf S}_k(A_0,\ldots,A_{k-1})$ such that no m + 1 sets among A 0,...,A k-1 have a nonempty intersection. It is shown that each ${\mathcal S}^m_k$ is an upper semi-lattice but not a lattice. The degree of the set of k-ary diagonally nonrecursive functions $\mathsf{DNR}_k$ is the greatest element of ${\mathcal S}^1_k$ . If 2 ≤ l < k, then 0 M is the only degree in ${\mathcal S}^1_l$ which is below a member of ${\mathcal S}^1_k$ . Each ${\mathcal S}^m_k$ is densely ordered and has the splitting property and the same holds for the lattice ${\mathcal L}^m_k$ it generates. The elements of ${\mathcal S}^m_k$ are exactly the joins of elements of ${\mathcal S}^1_i$ for $\lceil{k \over m}\rceil \leq i \leq k$. (shrink)
