Studies have shown that as MRI T2 relaxation time lengthens there is a shift toward more unbound or “free-water” and less partitioning of the protein/lipid molecules per unit volume. A shift toward less water partitioning or lengthened MRI T2 relaxation time is linearly related to reduced high frequency EEG amplitude, reduced short distance EEG coherence, increased long distance EEG coherence, and reduced cognitive functioning (Thatcher et al. 1998a; 1998b).
Efforts to reform medical education have emphasized the need to formalize instruction in medical ethics. However, the discipline of medical ethics education is still searching for an acceptable identity among North American medical schools; in these schools, no real consensus exists on its definition. Medical educators are grappling with not only what to teach (content) in this regard, but also with how to teach (process) ethics to the physicians of tomorrow. A literature review focused on medical ethics education among (...)North American medical schools reveals that instruction in ethics is considered to be vitally important for medical students. Agreement by medical educators on a possible core curriculum in ethics should be explored. To develop such a curriculum, deliberative curriculum inquiry by means of a targeted Delphi technique may be a useful methodology. However, the literature reveals that medical curricular change is notoriously slow. General implications for medical ethics education as a discipline are discussed. (shrink)
The North American wolf became extinct east of the Appalachians by 1800. To colonial legislators, uniform, colony-wide wolf bounties, as incentives to wolf-extermination, seemed the simplest solution to a perceived threat to livestock and European settlements. To local taxpayers, considerations of parsimony and fraud loomed just as large. This tension led to wolf extermination policies that were costly and often counterproductive. The bounty laws, as enacted, amounted to a fight against the abstract wolf, instead of against individual predators. Its (...) eventual 'success' brought about new troubles. Absent wolves, the eastern seaboard's ecosystem re-adjusted, allowing new predators and pests to flourish. (shrink)
This paper explores the social, legal, and political issues Wal-Mart faces in each of the three North American countries and suggests reasons for the quite significant differences. It also issues a call to Business and Society scholars to add prescriptive work to the already large body of descriptive work that has been collected.
Sahotra Sarkar’s Biodiversity and Environmental Philosophy is a welcome addition to the fields of environmental philosophy and the philosophy of science. First, his book has a rigorous and careful discussion of why we should preserve biodiversity. This is all the more important since much of environmental ethics has rested on normative claims which are unclear in meaning, appear unjustified at best and unjustifiable at worst, and are politically ineffective. Second, Sarkar is at home in the science of conservation biology and (...) offers important analyses of methodological issues in both ecology and conservation biology. Third, his book does not sustain what might be thought of as a “North American bias” but takes seriously environmental issues and perspectives from many different places like Australia and India. In this commentary, I raise worries and open questions that can be divided into four sections: (a) those concerning moral philosophy, (b) those concerning ecology and in particular whether we are in an extinction crisis, (c) how biodiversity is defined as a concept, and (d) what the aim and structure of conservation biology is. Ultimately, though my analysis is critical at some junctures, its purpose is to repay and hopefully improve on Sarkar’s rewarding analysis. Let me now turn from praise to criticism. (shrink)
The first two sections of this paper are devoted respectively to the criticisms of my views raised by Stephen Engstrom and Andrews Reath at a symposium on Kant's Theory of Freedom held in Washington D.C. on 28 December 1992 under the auspices of the North American Kant Society. The third section contains my response to the remarks of Marcia Baron at a second symposium in Chicago on 24 April 1993 at the APA Western Division meetings. The fourth section deals (...) with some general criticisms of my treatment of Kant's theory of freedom and its connection with transcendental idealism that have been raised by Karl Ameriks, who was also a participant in the second symposium, in an earlier piece published in Inquiry and by Paul Guyer in a review. The paper as a whole is thus an attempt to reformulate and clarify some of the central claims of my book in light of the initial critical reaction. (shrink)
Authenticity and diversity have both become catch words in contemporary North Atlantic societies. What has not, however, been widely explored is the interrelation ofthese two ideas. To this end, the present article takes up the sometime convergent, sometime divergent writings of Charles Taylor and Martin Heidegger, drawing out their thoughts on authenticity and showing how they can serve as a ground for a new form of cultural diversity. For both, authentic being-in-the-world affords us access to our own deep reservoir (...) of cultural material that is the necessary resource for fruitful engagement with other cultures.L’authenticité et la diversité font aujourd’hui figure de slogans dans les sociétés contemporaines de part et d’autre de l’Atlantique nord. En revanche, on a peu exploré les liens entre ces deux idées. À cette fin, cet article aborde les écrits tantôt convergents, tantôt divergents de Charles Taylor et Martin Heidegger pour prolonger leurs réflexions respectives sur l’authenticité et montrer en quoi elles peuventservir de fondement à une nouvelle forme de diversité culturelle. Pour tous deux, l’etre-au-monde authentique nous permet d’accéder au tréfonds du matériel culturel dont nous devons disposer pour que se nouent des rapports fructueux avec les autres cultures.

Sentences like (1a)-(1d) have attracted the attention of a number of authors (Jackendoff 1990, Matsumoto 1996, Talmy 1996, Gawron 2005). Each has both an event reading and a stative reading. For example, on what I’ll call the event reading of sentence (1a), a body of fog beginning in the vicinity of the pier moves pointwards, and on the other, stative reading, which I’ll call an extent reading, the mass of fog sits over the entire region between pier and point. The (...) event reading entails movement. The extent reading entails extension, the occupation of a region of space. Similarly, there is a reading of (1b) describing a crack-widening event, as well as a reading describing the dimensions of the crack, increasing in width along an axis extending from the north tower to the gate; and readings of (c) and (d) describing movement events as well as readings describing the configuration of the storm front and the snow respectively.

The dental preterite of weak verbs remains one of the most troublesome chapters of Germanic historical-comparative grammar. The morphological provenience of its dental formative -d- has been debated for nearly two centuries, and there is still no consensus on whether it is a reflex of one or more of the Indo-European dental suffixes, a grammaticalized form of the light verb d¯o ‘do’, or some mix of these. The category’s phonological development within early Germanic presents a whole series of other mysteries. (...) Why does the effect of syllable weight on umlaut in preterite stems differ in North and West Germanic, and for that matter why should umlaut be sensitive to syllable weight at all? Why does the dental preterite seem to undergo two distinct “phases” of umlaut in North Germanic, and why does this category alone undergo a special early phase of syncope in West Germanic? (shrink)
S. Jakowski introduced the discussive prepositional calculus D 2as a basis for a logic which could be used as underlying logic of inconsistent but nontrivial theories (see, for example, N. C. A. da Costa and L. Dubikajtis, On Jakowski's discussive logic, in Non-Classical Logic, Model Theory and Computability, A. I. Arruda, N. C. A da Costa and R. Chuaqui edts., North-Holland, Amsterdam, 1977, 37–56). D 2has afterwards been extended to a first-order predicate calculus and to a higher-order logic (cf. (...) the quoted paper). In this paper we present a natural version of D 2, in the sense of Jakowski and Gentzen; as a consequence, we suggest a new formulation of the discussive predicate calculus (with equality). A semantics for the new calculus is also presented. (shrink)
The Human Genome Project (HGP) represents a massive merging of science and technology in the name of all humanity. While the disease aspects of HGP-generated data have received the greatest publicity and are the strongest rationale for the project, it should be remembered that the HGP has, as its goal the sequencing of all 100,000 human genes and the accurate depiction of the ancestral and functional relationships among these genes. The HGP will thus be constructing the molecular taxonomic norm for (...) humanity. Currently the HGP genomic baseline is almost exclusively skewed toward North Atlantic European lineages through the extensive use of the Centre d’Études du Polymorphisme Humaine (CEPH) data set. More recently, the HGP has shifted to the use of volunteer donors since adequate informed consent had not been secured from the CEPH families. No evidence exists that either the CEPH families or the current volunteers are the most appropriate demographic or evolutionary lineages for the functional genomic studies that will guide production of new DNA based drugs, targeted therapeutics and gene-based diagnostics. The lack of scientific representativeness of the HGP is a serious impediment to its broad applicability. Yet this can be remedied, and five alternative sampling strategies are presented. In response to the current exclusionary design of the HGP, there is noteworthy caution and skepticism in the African American community concerning genetic studies. The Manifesto on Genomic Studies Among African Americans reflects both a desire to be systematically included in federally funded genomic studies and a desire to maintain some control over the interpretation and application of research results. Representative sampling in the HGP is seen as an international human rights issue with domestic ethical implications. (shrink)
Many argue that transgenic technology will have wide-ranging implications for farmers in developing nations. A key concern is that competencies may be destroyed by predominantly foreign multinational transgenic technologies, exacerbating problems of social exclusion in the case of subsistence farmers. Conversely, those that fail to adopt the technology may become uncompetitive, particularly in commodity-based export markets. Drawing on interview data conducted in Brazil and supporting data collected in North America, Europe and China, we found that the impact of transgenic (...) technology varies. It has less impact on farmers that adapt the products to their crop systems and environment, and greater negative implications for less formally educated subsistence farmers in consequence of both complexity and compatibility. Earlier attempts at industrializing agriculture through technological innovation led to vastly improved agricultural output and exports, but the benefits of productivity was not equitably distributed [D. Lee: 2005, American Journal of Agricultural Economics 87(5), 1325–1334], nor was it designed to meet specific local environmental and socioeconomic farmer conditions, exacerbating social exclusion. Multinationals attempting to introduce transgenic technology without considering the broader social and ethical implications will invite resistance. We discuss the implications for policy makers, multinationals and small-scale farmers. (shrink)
For quite some time now, there have been discussions and debates in North America in the field of ethics concerning professionalization . From a talk given to graduate and undergraduate university students, the author tells the personal journey of an ethicist in the province of Quebec, Canada, and offers a narrative to illustrate some of the issues she faced since starting her work in the field of ethics at the end of the 1990s. Instead of taking the usual “for” (...) and “against” positions, the author addresses the issue of professionalization of healthcare ethics from her own point of view. Referring to her experience with ethics committees and research ethics boards and to the works of George A. Legault in Crise d’identité professionnelle et Professionnalisme (Presses de l’Université du Québec, Sainte-Foy, 2003 ), she pleads for the development of practice standards and the creation of a deliberative process (see Kirby and Simpson in this issue of HEC Forum 2012 ), a dialogical space for assuring professionalism in healthcare ethics interventions, not solely the act of becoming a profession.

A new recommendation has appeared in the Ethnic Dining Guide of Washingtoon, capital of the Unconscious States of Amurrica, put out by Tailor Coward III, Director of the Mercantilist Center and Professor of Shriekonomics at George Madison University, which is scattered across several municipalities in the northern Vagina suburbs of Washingtoon. Tailor’s father was from the clothier branch of the famous English playwright’s family, but had to flee to Amurrica when his stitch in time saved only eight. After marrying a (...) nice girl from Old Teashirt, they moved to Hoople, Southern North Dakota, where Tailor would become the regional chess champion at age 6, only to be defeated some years later by the 4-year old I.M.A. Bach, great-great-great-greatgreat-great-great grandson of P.D.Q. Bach, who had studied obscure gambits with Bobby Fischer’s dog. (shrink)
I begin by recounting the market demands that created an opportunity for me to teach business ethics in the College of Business at St. Cloud State University. The AACSB and my educational institution focused amorphous social demands for better business practices into a specific demand for a philosophy Ph.D. to teach business ethics. I felt frustrated teaching business ethics because of my inexperience and the eclectic nature of the field. I, and many others, searched for something to unify the many (...) topics of the field. This search was one of the factors that led to BEQ’s appearance in 1991. The first issue marked a milestone in the continuing search fortheory and the legitimization of the field. It focused previous discussions and was remarkably prescient. While it is unlikely that we will reach a consensus about how to understand the field, if consensus ever comes close to occurring, I argue that it will not coalesce over stakeholder theory. I examine two theories that could be used as a grand unified theory (GUT) of business ethics: Integrated Social Contracts Theory and my own institutional theory that expands on the work of Douglass North’s view of economic institutions. I usethe discussion of these GUTs to develop criteria of what a successful GUT might look like. Based on these criteria, I argue that theinstitutional theory has a better chance of succeeding, but recognize that business ethics GUTs are primarily heuristic; many different types of theories can be helpful. Lastly, I discuss whether it is pretentious and overbearing to argue for a GUT. I argue that it need not be. (shrink)
In some languages every statement must contain a specification of the type of evidence on which it is based: for example, whether the speaker saw it, or heard it, or inferred it from indirect evidence, or learnt it from someone else. This grammatical reference to information source is called 'evidentiality', and is one of the least described grammatical categories. Evidentiality systems differ in how complex they are: some distinguish just two terms (eyewitness and noneyewitness, or reported and everything else), while (...) others have six or even more terms. Evidentiality is a category in its own right, and not a subcategory of epistemic or some other modality, nor of tense-aspect. Every language has some way of referring to the source of information, but not every language has grammatical evidentiality. In English expressions such as I guess, they say, I hear that, the alleged are not obligatory and do not constitute a grammatical system. Similar expressions in other languages may provide historical sources for evidentials. True evidentials, by contrast, form a grammatical system. In the North Arawak language Tariana an expression such as "the dog bit the man" must be augmented by a grammatical suffix indicating whether the event was seen, or heard, or assumed, or reported. This book provides the first exhaustive cross-linguistic typological study of how languages deal with the marking of information source. Examples are drawn from over 500 languages from all over the world, several of them based on the author's original fieldwork. Professor Aikhenvald also considers the role evidentiality plays in human cognition, and the ways in which evidentiality influences human perception of the world.. This is an important book on an intriguing subject. It will interest anthropologists, cognitive psychologists and philosophers, as well as linguists. (shrink)
Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. (...) For all regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole. (shrink)
Wikipedia is a free encyclopedia that is written and edited entirely by visitors to its website. I argue that we are misled when we think of it in the same epistemic category with traditional general encyclopedias. An empirical assessment of its reliability reveals that it varies widely from topic to topic. So any particular claim found in it cannot be relied on based on its source. I survey some methods that we use in assessing specific claims and argue that the (...) structure of the Wikipedia frustrates them. (shrink)
In one study funded by the United States Department of Agriculture, people from North Dakota were interviewed to discover which moral principles they use in evaluating the morality of transgenic organisms and their introduction into markets. It was found that although the moral codes the human subjects employed were very similar, their views on transgenics were vastly different. In this paper, the codes that were used by the respondents are developed, compared to that of the academically composed Belmont Report, (...) and then modified to create the more practical Common Moral Code. At the end, it is shown that the Common Moral Code has inherent inconsistency flaws that might be resolvable, but would require extensive work on the definition of terms and principles. However, the effort is worthwhile, especially if it results in a common moral code that all those involved in the debate are willing to use in negotiating a resolution to their differences. (shrink)
Categories, as mental structures, are more than simply sums of property frequencies. A number of recent studies have supported the view that the properties of categories may be organised along functional lines and possibly dependency structures more generally. The study presented here investigates whether earlier findings reflect something unique in the English language/North American culture or whether the functional structuring of categories is a more universal phenomenon. A population of English-speaking Americans was compared to a population of Cantonese-speaking Hong (...) Kong Chinese. The findings clearly support the view that functional influences on category centrality are universal (or at least common to Cantonese-speaking Hong Kong Chinese and English-speaking Americans), albeit with specific cross-cultural/cross-linguistic group differences in the particular properties that are considered central to categories.
