The book "Philosophical Foundations of Neuroscience" is an engaging criticism of cognitive neuroscience from the perspective of a Wittgensteinian philosophy of ordinary language. The authors' main claim is that assertions like "the brain sees" and "the left hemisphere thinks" are integral to cognitive neuroscience but that they are meaningless because they commit the mereological fallacy—ascribing to parts of humans, properties that make sense to predicate only of whole humans. The authors claim that this fallacy is at the heart of Cartesian (...) dualism, implying that current cognitive neuroscientists are Cartesian dualists. Against this claim, we argue that the fallacy cannot be committed within Cartesian dualism either, for this doctrine does not allow for an intelligible way of asserting that a soul is part of a human being. Also, the authors' Aristotelian essentialistic outlook is at odds with their Wittgensteinian stance, and we were unconvinced by their case against explanatory reductionism. Finally, although their Wittgensteinian stance is congenial with radical behaviorism, their separation between philosophy and science seems less so because it is based on a view of philosophy as a priori. The authors' emphasis on the a priori, however, does not necessarily commit them to rationalism if it is restricted to conceptual or analytical truths. (shrink)

We propose a model mechanism for the initiation and spatial positioning of teeth primordia in the alligator, Alligator mississippiensis. Detailed embryological studies by Westergaard and Ferguson have shown that jaw growth plays a crucial role in the developmental patterning of the tooth initiation process. Based on biological data we develop a dynamic patterning mechanism, which crucially includes domain growth. The mechanism can reproduce the spatial pattern development of the first seven teeth primordia in each half jaw of A. mississippiensis. The (...) results for the precise spatio-temporal sequence compare well with experiment. Simulation of the model also predicts that certain transplantations can alter the spatial sequence of teeth primordia initiation. (shrink)

This volume gives an overview of the subject of mathematical logic, placing primary emphasis on theory instead of the development of skills. It contains chapters on the history of logic, first and second order quantification theory, metatheory, and some of the philosophical implications of recent work in the field. Needless to say, none of these topics is treated in any great detail owing to the space limitations. Care has been taken by the author, however, to insure that his discussions do (...) not trade mistakes and clarity for brevity. Each section provides the reader with a grasp of the central issues and adequate information to approach more advanced literature with some confidence. The treatment of topics such as recursive functions, Skolem's paradox for set theory, and the place of mathematical logic in the study of philosophy is rarely found in introductory treatments. No special training in either mathematics or Logic is presupposed by any of the sections. Ample exercises are included which are, in some cases, quite challenging. Answers to many of these are provided. In addition, there is also a useful annotated bibliography.--R. P. M. (shrink)

Perhaps no work since John Rawls’ A Theory of Justice has attracted as much recent attention as Robert Nozick’s case for a minimal state—an ingeniously argued critique, not only of antinomian individualism, but also of liberal and socialist contractualism. It might be added that the book is no solace either to more conservative political theorists, who lament state incursion into private life, but whose political structures exhibit either actual or potential constriction of human life. Nozick’s book is both a searching (...) examination of the limitations of utilitarian consequentialism and the redistributivism of Rawls. His essential theme is that "a minimal state limited to the narrow functions of protection against force, theft, fraud, enforcement of contracts etc., is justified; that any more extensive state will violate persons’ rights not to be forced to do certain things, and is unjustified; and that the minimal state is inspiring as well as right." It is also Nozick’s contention that the coercive power of the state should not be used paternalistically to prohibit activities to people for their own protection, or to force some citizens to aid others. The last part of the book is a framework for Nozick’s utopia, and it is in this section that an essentially theoretical approach, amplified by little political or sociological data, exhibits its defects. One suspects that almost all states started with simplistic hopes for minimal coercive activity, and succumbed almost inevitably to the metastasis of function as socio-political life grew in size and complexity. Night watchmen become more than night watchmen when more than watching is needed. Moreover, Nozick’s utopia would seem to necessitate, at least by implication, coercive redistributivism and some kind of compensatory or levelling taxation process. This reviewer is not sure that he understands precisely what Nozick considers correct property theory in a state of nature. The author modestly asserts the tentative, incomplete, and conjectural nature of his work. But the taxed and manipulated citizen who grows in sympathy for the sentiments of Proudhon’s famous litany should welcome this highly literate and well argued case.—R.P.M. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Ray splitting is a universal phenomenon that occurs with appreciable amplitude in all wave systems when the properties of the system change on a scale smaller than the wave length. We study the quantum implications of ray splitting theoretically and experimentally with the help of ray-splitting billiards in one and two dimensions. We show that Gutzwiller's trace formula works even in the context of ray-splitting systems provided reflection and transmission of waves at ray-splitting boundaries is properly included.

Contractualism is one of the most promising ‘centers of gravity’ in business ethics. In this guest editorial we provide a concise roadmap to the field, sketching contractualism’s historic and disciplinary antecedents, the basic argumentative structure of the contract model, and its boundary conditions. We also sketch two main dimensions along which contributions to the contractualist tradition can be positioned. The first dimension entails positive versus normative theorizing – does a given contribution analyze the world as it is or how it (...) ought to be? The second dimension involves four different levels of analysis that are commonly employed in contractualist business ethics: the nano, micro, meso, and macro levels. We then proceed to position the articles comprising this special issue along these two dimensions. (shrink)

Background: Although fair distribution of healthcare services for older patients is an important challenge, qualitative research exploring clinicians’ considerations in clinical prioritisation within this field is scarce. Objectives: To explore how clinicians understand their professional role in clinical prioritisations in healthcare services for old patients. Design: A semi-structured interview-guide was employed to interview 45 clinicians working with older patients. The interviews were analysed qualitatively using hermeneutical content analysis. Participants: 20 physicians and 25 nurses working in public hospitals and nursing homes (...) in different parts of Norway. Results and interpretations: The clinicians struggle with not being able to attend to the comprehensive needs of older patients, and being unfaithful to professional ideals and expectations. There is a tendency towards lowering the standards and narrowing the role of the clinician. This is done in order to secure the vital needs of the patient, but is at the expense of good practice and holistic role modelling. Increased specialisation, advances and increase in medical interventions, economical incentives, organisational structures, and biomedical paradigms, may all contribute to a narrowing of the clinicians’ role. Conclusion: Distributing healthcare services in a fair way is generally not described as integral to the clinicians’ role in clinical prioritisations. If considerations of justice are not included in clinicians’ role, it is likely that others will shape major parts of their roles and responsibilities in clinical prioritisations. Fair distribution of healthcare services for older patients is possible only if clinicians accept responsibility in these questions. (shrink)

Background Regarding controversial medical services, many have argued that if physicians cannot in good conscience provide a legal medical intervention for which a patient is a candidate, they should refer the requesting patient to an accommodating provider. This study examines what US physicians think a doctor is obligated to do when the doctor thinks it would be immoral to provide a referral. Method The authors conducted a cross-sectional survey of a random sample of 2000 US physicians from all specialties. The (...) primary criterion variable was agreement that physicians have a professional obligation to refer patients for all legal medical services for which the patients are candidates, even if the physician believes that such a referral is immoral. Results Of 1895 eligible physicians, 1032 (55%) responded. 57% of physicians agreed that doctors must refer patients regardless of whether or not the doctor believes the referral itself is immoral. Holding this opinion was independently associated with being more theologically pluralistic, describing oneself as sociopolitically liberal, and indicating that respect for patient autonomy is the most important bioethical principle in one's practice (multivariable ORs, 1.6–2.4). Conclusions Physicians are divided about a professional obligation to refer when the physician believes that referral itself is immoral. These data suggest there is no uncontroversial way to resolve conflicts posed when patients request interventions that their physicians cannot in good conscience provide. (shrink)

ABSTRACT:Organization theory and business ethics are essentially the positive and normative sides of the very same coin, reflecting on how human cooperative activities are organized and how they ought to be organized respectively. It is therefore unfortunate that—due to the relatively impermeable manmade boundaries segregating the corresponding scholarly communities into separate schools and departments, professional associations, and scientific journals—the potential symbiosis between the two fields has not yet fully materialized. In this essay we make a modest attempt at establishing further (...) connectivity by surveying the terrain covered by the two disciplines jointly, as if the boundaries between them did not matter. We commence by providing a concise overview of the organization theory discipline for interested non-specialists from the field of business ethics. Next, we proceed to point out four research themes commonly investigated by members of both communities, and also a variety of organization-theoretical perspectives on each. In the final part of this essay we explore what organization theory has to offer business ethics, and what the boundaries of that potential contribution are. We warn skeptical readers in advance that the spirit and tone of our essay is most definitely upbeat, as we are convinced that the potential for symbiosis between the two fields is vast and inspiring, even though it has only been unleashed partially and incidentally thus far.

Although Toffler has not written an in-depth philosophical analysis of social problems, he certainly has written a highly readable popular diagnosis of the phenomenon of cultural change which social philosophers should be considering, and has given a synoptic view of contemporary culture similar to Pitirim Sorokin's popular Crisis of Our Age in the forties. Toffler's thesis is "that there are discoverable limits to the amount of change that the human organism can absorb, and that by endlessly accelerating change without first (...) determining these limits, we may submit masses of men to demands they simply cannot tolerate." Future shock is, therefore, both the physical and psychological impairment caused by reluctance and inability to absorb the rapid changes that an age of discontinuity produces. Psychic distress is identified in Leon Festinger's arresting phrase, "cognitive dissonance," the rejection or denial of information that challenges preconceptions. Physical distress is analyzed by such interesting research tools as the Rahe Life-Change Units Scale which attempts to correlate change factors with physical health. The philosophic base of modern life is seen in a Heraclitean or Bergsonian flux which ontologizes change itself and sees social and political conflict inevitably provoked by rapid change confronting an older society whose substantialist structures reflect more the stable and enduring values of an older culture. It is from the vantage point of change theory that Toffler explains the contemporary turmoil in domestic, social, political, and religious realms; and although he does not employ the more formal idiom of a Vico or Spengler in the discussion of Zeitgeist, he recognizes thought and life style as even more significant than ever in a culture in which communication is so widespread and immediate. He uses the imagery of eight hundred 62-year lifetimes to illustrate man's history of the last 50,000 years, noting the comparative stability of the previous segments and the bewildering rapidity of change cycle of idea, application, and diffusion in the last sixty-year period. He analyzes progressively the accelerative thrust that creates conflict between cultures and generations; describes the typical attitudes of citizens in an Age of Transience towards time, things, places, people, organization, and ideas; and sees "modular" man as a being for whom permanence of marriage, career, educational values, and convictions yields to "temporariness." Organizations in such a climate are characterized by lateral rather than hierarchical power relationships in which "super-industrial man," committed more to his craft than to his company, assumes more decision-making responsibility in an "adhocracy" of transient values and relationships. Toffler interestingly sees bureaucracy on the decline, technology as contributing to plurality of choice rather than to standardization, and to a kinetic imagery of impermanence in aesthetics. For the most part, Toffler, the diagnostician, resists the temptation to be the pleader. His happily infrequent divagations produce less than satisfactory critiques of family life, education, and genetic engineering. It is inevitable that this book will be criticized by specialists as bewilderingly diffuse, and verging at times on science fiction; it is possible too that the strategy of "social futurism" suggested by the author will elicit less than undiluted enthusiasm, and that inexact references to Toynbee and Maritain may be questioned. But the essential purpose of this volume to give a unified vision of contemporary culture in terms of the adaptive reaction to change--all this has been admirably realized. And one feels that the author indeed possesses the vision and research tools for particularized study in the areas treated here quite generally.--R. P. M. (shrink)

This introduction to formal logic is one of the few paperbacks available that provides a broad survey of the field. In addition to a clear presentation of sentential and first order quantificational logic, there is a discussion of the philosophical significance of recent work by Church, Gödel, and Tarski. The proof technique employed throughout is the indirect argument. Since proofs of this sort can be converted into mechanical tests of validity, it is easier than most for a beginning student to (...) grasp. Furthermore, this style of argument has long been recognized as the most obvious method of showing arguments in ordinary language to be invalid. Interesting treatments of the construction of decision machines, the nature of formal systems, and the application of logic to mathematics are included in the last section. Numerous exercises are included for which some answers are provided.--R. P. M. (shrink)

Contractualism conceives of firm-stakeholder relations as cooperative schemes for mutual benefit. In essence, contractualism holds that these schemes, as well as the normative principles that guide and constrain them, are ultimately ratified by the consent and endorsement of those subject to them. This paper explores the empirical validity of a contractualist perspective on firm-stakeholder relations. It first develops a typology of firm-stakeholder contracting problems. It subsequently confronts this typology with empirical data collected in an interview study of concrete stakeholder management (...) practices, involving in-depth research interviews with forty-four managers working in the Dutch financial services industry. The findings of this theory-building study suggest that there are limits to the applicability of the contract model in the context of stakeholder management, and that disregarding either the model or its limitations may lead to highly ineffective firm-stakeholder relations.

This handsome volume is an outgrowth of Giambattista Vico, An International Symposium, edited by Giorgio Tagliacozzo and Hayden White and published in 1969, in which Vichian influences were explored by distinguished scholars in diverse fields. The original volume was meant to be exploratory in nature, analyzing Vico’s sometimes obscure thought in terms of historical theory and contemporary humanistic relevance.

The objectives of this study were to develop a high-density chromosome bin map of homoeologous group 7 in hexaploid wheat, to identify gene distribution in these chromosomes, and to perform comparative studies of wheat with rice and barley. We mapped 2148 loci from 919 EST clones onto group 7 chromosomes of wheat. In the majority of cases the numbers of loci were significantly lower in the centromeric regions and tended to increase in the distal regions. The level of duplicated loci (...) in this group was 24% with most of these loci being localized toward the distal regions. One hundred nineteen EST probes that hybridized to three fragments and mapped to the three group 7 chromosomes were designated landmark probes and were used to construct a consensus homoeologous group 7 map. An additional 49 probes that mapped to 7AS, 7DS, and the ancestral translocated segment involving 7BS also were designated landmarks. Landmark probe orders and comparative maps of wheat, rice, and barley were produced on the basis of corresponding rice BAC/PAC and genetic markers that mapped on chromosomes 6 and 8 of rice. Identification of landmark ESTs and development of consensus maps may provide a framework of conserved coding regions predating the evolution of wheat genomes. (shrink)
