We are concerned here with recursive function theory analogs of certain problems in chromatic graph theory. The motivating question for our work is: Does there exist a recursive (countably infinite) planar graph with no recursive 4-coloring? We obtain the following results: There is a 3-colorable, recursive planar graph which, for all k, has no recursive k-coloring; every decidable graph of genus p ≥ 0 has a recursive 2(χ(p) - 1)-coloring, where χ(p) is the least number of colors which will suffice (...) to color any graph of genus p; for every k ≥ 3 there is a k-colorable, decidable graph with no recursive k-coloring, and if k = 3 or if k = 4 and the 4-color conjecture fails the graph is planar; there are degree preserving correspondences between k-colorings of graphs and paths through special types of trees which yield information about the degrees of unsolvability of k-colorings of graphs.

Milton Friedman has argued that corporations have no responsibility to society beyond that of obeying the law and maximizing profits for shareholders. Individuals may have social responsibilities according to Friedman, but not corporations.When executives make contributions to address social problems in the name of the corporation, they are doing so with other people''s (shareholders'') money. The responsibility of corporate executives is a fiduciary one, to serve as an agent for the corporation''s shareholders, and to uphold shareholders'' trust, which requires executives (...) to maximize the return to their shareholders, who can then, if they choose, contribute their own money to worthy causes.

This paper was motivated by what we see as an inconsistency between a 1988 paper by Brennan and Buchanan expressing concern that public choice might erode public confidence in government and previous work by Buchanan, in particular Buchanan. The one advantage we saw with the 1988 paper was that it, all by itself, is all one needs to dismiss MacLean’s depiction of Buchanan as an ideologically rigid extremist. We also found the same inconsistency occurring simultaneously in Buchanan’s writing in 1979. (...) Yet, based on Wagner, we conclude that such inconsistencies may reflect a strength in Buchanan’s scholarship. (shrink)

We completely characterize the simple majority weighted voting game achievable hierarchies, and, in doing so, show that a problem about representative government, noted by J. Banzhaf [Rutgers Law Review 58, 317–343 (1965)] cannot be resolved using the simple majority quota. We also demonstrate that all hierarchies achievable by any quota can be achieved if the simple majority quota is simply incremented by one.

The literature fails to reflect general agreement over the nature of the services and procedures provided by bioethicists, and the training and core competencies this work requires. If bioethicists are to define their activities in a consistent way, it makes sense to look for common ground in shared communities of practice. We report results of a survey of the services and procedures among bioethicists affiliated with the University of Toronto Joint Centre for Bioethics (JCB). This is the largest group of (...) bioethicists working in healthcare organizations in Canada. The results suggest there are many common services and procedures of JCB bioethicists. This survey can serve as a baseline for further exploration of the work of JCB bioethicists. Common practices exist with respect to the domains of practice, individual reporting relationships, service availability within business hours and the education and training of the bioethicist.

Background This paper describes the design, implementation, and process outcomes from three public deliberations held in three tribal communities. Although increasingly used around the globe to address collective challenges, our study is among the first to adapt public deliberation for use with exclusively Indigenous populations. In question was how to design deliberations for tribal communities and whether this adapted model would achieve key deliberative goals and be well received.Methods We adapted democratic deliberation, an approach to stakeholder engagement, for use with (...) three tribal communities to respect tribal values and customs. Public deliberation convenes people from diverse backgrounds in reasoned reflection and dialogue in search of collective solutions. The deliberation planning process and design were informed by frameworks of enclave deliberation and community-based participatory research, which share key egalitarian values. The deliberations were collaboratively designed with tribal leadership and extensive partner input and involvement in the deliberations. Each deliberation posed different, locally relevant questions about genomic research, but used the same deliberation structure and measures to gauge the quality and experience of deliberation.Results A total of 52 individuals participated in the deliberations across all three sites. Deliberants were balanced in gender, spanned decades in age, and were diverse in educational attainment and exposure to health research. Overall, the deliberations were positively evaluated. Participant perceptions and external observer datasets depict three deliberations that offered intensive conversation experiences in which participants learned from one another, reported feeling respected and connected to one another, and endorsed this intensive form of engagement.Conclusion The adapted deliberations achieved key deliberative goals and were generally well received. Limitations of the study are described. (shrink)

This study compares the level of ethics research published in 25 business-ethics journals and the Top-40 journals for the accounting, finance, and marketing disciplines. This research documents an increasing level of ethics research in the accounting and marketing disciplines starting in 1992. While the level of finance doctorates reported by the Association to Advance Collegiate Schools of Business (AACSB) has increased at a higher rate (40.4%) than accounting (18.4%) and marketing (32.2%) since 1995, this increase has not been reflected in (...) the level of ethics scholarship in finance. The level of ethics scholarship in finance remained relatively constant between 1987 and 2005 at an average of seven coauthor-adjusted articles per year. However, both the accounting and marketing disciplines now regularly publish approximately 50 coauthor-adjusted articles each year. (shrink)

This paper considers prevailing environmental policy in the United States with the emphasis on liberty, markets, utilizing information, entrepreneurial discovery, and the economic analysis of political decisions. The general discussion is illustrated by the concern over global warming and policies for addressing this concern. The political incentives to confront environmental problems directly with mandates, restrictions, and subsidies ignore the power of liberty and market incentives to solve problems by fostering an impressive network of information transfer, increasing innovation, and expanding prosperity. (...) Indeed, most environmental policies systematically suppress liberty, censor the communication of information, and retard innovation and prosperity, with the result that they provide less environmental quality at greater cost than is possible. While such flawed policies might be justified in cases where pollution problems pose clear, serious, and immediate threats, we argue this is not true of global warming, and the most effective response to concerns over carbon emissions may be limiting the discretionary power of government to take direct action and rely on the indirect effects of liberty and market incentives to move us beyond the petroleum age more quickly and efficiently than will result from the direct action of government.

Based on seventeenth- and eighteenth-century accounts written by and for slavers, this article investigates the provisioning of the French Middle Passage. As the transatlantic trade in African captives developed, foodstuffs for the feeding of both Europeans and Africans figured prominently in a specifically Atlantic system of commodity exchanges. The trade in foodstuffs depended most heavily on African subsistence systems encountered along the coasts of West Africa, but a surprising quantity of French and other European foodstuffs were embarked specifically for the (...) Middle Passage, revealing, I argue, the precariousness of conditions of trade and of European slaving factories. As a key element of Atlantic political economy, the study of food and its transatlantic provisioning networks sheds light not only on the governance and regulation of the networks themselves, but also on the ability of early modern states to establish and maintain metropolitan control, on the growth of local, colonial forms of autonomy and authority, and on the complex systems of ‘national’ and colonial interdependence that lay behind the expansion of every Atlantic colony. I conclude that this study of provisioning demonstrates that however fractured and differentiated, imperial power was an irrefutable aspect of colonial continuity. (shrink)

Business professions are increasingly faced with the question of how to best monitor the ethical behavior of their members. Conflicts could exist between a profession's desire to self-regulate and its accountability to the public at large. This study examines how members of one profession, public accounting, evaluate the relative effectiveness of various self-regulatory and externally imposed mechanisms for promoting a climate of high ethical behavior. Specifically, the roles of independent public accountants, regulatory and rule setting agencies, and undergraduate accounting education (...) are investigated. Of 461 possible respondents, 230 questionnaires (a 49.6% response rate) indicated that the profession's own rule setting body (The American Institute of Certified Public Accountants) and the use of peer review were perceived as the most effective mechanisms, while government regulation was ranked least. Respondents also evaluated the extent to which ethics should be covered in the accounting curriculum. For every course, the CPAs believed a greater emphasis on ethics is appropriate than presently exists. Suggestions for more effectively integrating ethics into accounting courses are made. Finally, respondents were also asked whether in answering the questionnaire they used a definition of ethics as either the Professional Code of Conduct or a moral and philosphical framework for guiding beliefs. Those who viewed ethics as abiding by a professional code had more confidence in the mechanisms addressed in this study to aid the public accounting profession's ability to ensure high ethical standards of conduct. Methodological implications of this distinction for future studies in business ethics are discussed. (shrink)

Southern Appalachia is unique among agroecological regions of the American South because of the diverse environmental conditions caused by its mountain ecology, the geographic and commercial isolation of the region, and the relative cultural autonomy of the people that live there. Those three criteria, combined with a rich agricultural history and the continuance of the homegardening tradition, make southern Appalachia an area of relatively high crop biodiversity in America. This study investigated the history and survival of traditional heirloom vegetable crops (...) in western North Carolina and documented 134 heirloom varieties that were still being grown. I conducted interviews with 26 individuals from 12 counties in western North Carolina. I used a snowball sampling method to identify individuals or communities that maintained heirloom vegetable varieties, and used the “memory banking” of farmers’ knowledge as a strategy to complement the gathering of seed specimens. Most of the varieties were grown and saved by homegardeners; beans were the most numerous. Results indicate that usually only one or two individuals in a community maintained significant numbers of heirloom varieties and that many communities have lost their heirloom vegetable heritage altogether. The decline of the farming population combined with a lack of cultural continuance in family seed-saving traditions threatens the ability of communities to maintain crop biodiversity. Some of the cultivars may represent the last (small) populations of endangered varieties. (shrink)

Perched on the ramparts of Volterra last July, I gaze over i dolci colli toscani, the sweet hills of Tuscany, drenched in summer sun. Warm, content and at peace, I am bemused at how much at home I feel in this strange land. I have felt this way since 1991 when I returned for the first time to la bell' Italia thirty-seven years after having lived in Rome as a young child in a Foreign Service family. In its sensuous beauty (...) and riotous disorder, Rome was stunning. My wife Eileen and I explored old childhood haunts, including the Embassy apartment residences on viale villa Graziole where my family had lived for four years in Rome—two consecutive two-year posts—in the 1950s. Memory cells exploding, I was assailed by vivid images from childhood. Once when I was five or six, my brother David and I accompanied our housemaid Marcella to her simple country home and joined villagers in the fields as they all turned out—men, women, and children—to harvest the bean crop. As dusk set in, fires were lit, simple musical instruments appeared with the wine, and the feasting and dancing began. Bonfires were soon aglow for miles up and down the sweet rolling hills.

We show how a simple nonlinear dynamical system (the discrete quadratic iteration on the unit segment) can be the basis for modelling the embryogenesis process. Such an approach, even though being crude, can nevertheless prove to be useful when looking with the two main involved processes:i) on one hand the cell proliferation under successive divisions ii) on the other hand, the differentiation between cell lineages. We illustrate this new approach in the case of Caenorhabditis elegans by looking at the early (...) stages of embryogenesis, up to several hundreds of cells (lima bean larval stage). We show how the many results that have been obtained by several groups can be interpreted in terms of values for the parameters controlling the dynamical system. Furthermore, we can extend the model to the cases of genetic mutations. More precisely the teratogenetic and lethal effects are associated with abnormal variation of the control parameters with time.

These 13 essays by noted American and German scholars provide a focused discussion of many of the issues raised by the integration of philosophical and psychological theories of moral development. The essays pivot around two key contributions, by Lawrence Kohlberg and his associates and by JA1⁄4rgen Habermas. Kohlberg's major work was a description of the stages of development of moral understanding in children. This book contains the final formulation of his view of the end point of moral development (Stage 6). (...) Habermas's insightful response to that formulation, which seeks to fit Kohlberg's perceptions into the framework of a communicative ethics, is an important extension of his own moral theory. In three parts, the essays map out the relationship between philosophy and psychology in the study of the moral domain, explore the way the moral point of view is understood within Kohlberg's cognitive-developmental model, and discuss the place of moral development in terms of various models of personality and decision making. The contributors are Augusto Blasi, Dwight R. Boyd, Rainer Dobert, Wolfgang Edelstein, JA1⁄4rgen Habermas, Helen Haste, Monika Keller, Lawrence Kohlberg, Charles Levine, Mordecai Nisan, Gil G. Noam, Gertrud Nunner-Winkler, Bill Puka, Ernst Tugendhat, and Thomas E. Wren. Thomas E. Wren is Professor of Philosophy at Loyola University of Chicago. The Moral Domain is included in the series Studies in Contemporary German Social Thought, edited by Thomas McCarthy. (shrink)

This piece, included in the drift special issue of continent. , was created as one step in a thread of inquiry. While each of the contributions to drift stand on their own, the project was an attempt to follow a line of theoretical inquiry as it passed through time and the postal service(s) from October 2012 until May 2013. This issue hosts two threads: between space & place and between intention & attention . The editors recommend that to experience the (...) drifiting thought that attention be paid to the contributions as they entered into conversation one after another. This particular piece is from the BETWEEN SPACE & PLACE thread: April Vannini, Those Between the Common * Laura Dean & Jesse McClelland, Ballard: A Portrait of Placemaking * Amara Hark Weber, Crossroad * Isaac Linder & Berit Soli-Holt, The Call of the Wild: Terro(i)r Modulations * Ashley D. Hairston, Momma taught us to keep a clean house * Sean Smith, The Garage (Take One) * * * * Momma taught us to keep a clean house. Dust the wood furniture every two weeks. Clean the bathrooms once a week. Wipe down the baseboards once a season (Those damn baseboards. I still got bruises on my knees from scrubbing those things). Sweep away the cobwebs—and pray that those spiders are either dead or delirious (Livin in the country don’t mean you like bugs, especially the ones with too many legs ). Didn’t matter that the house was full of stuff: Great-Grandma’s heirloom dresser, that weird Mammy salt shaker and matching Uncle Tom pepper grinder (Where the hell did Momma get those P.O.S.’s?), the outdated drapes from Belks, Dad’s favorite wooden TV tray, and that uuuuugly love seat that some crazy uncle thought was a glorious find from the Salvation Army (Momma tried to make it pretty with some pillows, but no amount of love could help that seat). Spring Cleaning meant pullin all that furniture away from the walls and holdin your breath to see what time collected in the crevices. Then you gotta be careful not to breathe out too heavy cause the dust would go flying fore you got a chance to catch it. If you didn’t, you’d quickly find out if you’re allergic to dust. Quarter cup of lemon Lysol in a bucket of steaming water and an old wash rag. Maybe two. A dust towel and citrus-scent Pledge. Me and my brothers would fight over who cleaned what. Somehow the twins always got the easy stuff: vacuuming or moving dirt around with the feather-duster. Finishing in enough time to fly down the street on their bikes with the neighborhood kids. Older sister never got off that easy. Each of my stubby fingers morphed into plump, lemon-fresh golden raisins by the time that whole damn house was done. I would finish just in time to sit with Nadine on the porch, counting the seconds til the sun turned off and the fireflies fluttered on. The craziest thing: despite all that cleaning, the house still smelled like Momma’s cookin. That Old House. Might have been some of Grandma’s and Great-Grandma’s cookin mixed in there too. Pork chops. Ham hock soaked in collards. Pinto beans and mustard greens. Corn bread and my Auntie’s famous macaroni and cheese. Didn’t matter if the oven was cold and the valve of the gas stove had been shut for days. A stranger woulda thought someone’d been slavin away in that kitchen for a week straight. No Sweet Citrus & Zest Fabreze back then. Lysol would mask the odors for a little while. Not long enough to overpower the 50 years of goodness marinated in buttermilk, kneaded with lard, and fried in Crisco that’d been embedded in the wallpaper and window treatments. All that grime—dead skin, hair follicles, Carolina clay, carpet lint, yippee-little-dog fur—was evidence of life. We were a socially-awkward newly-minted teenager, two rowdy twin boys, a multi-tasking mother, and a road-warrior father. Eventually a strangely-feline Yorkie was added to the mix. And don’t forget about the stray distant relative stopping by unannounced. No corner of that damn house was unmarked. Hand-sewn pillows in the living room that we were forbidden to breathe on somehow had tiny burnt orange paw prints on them (sneaky little dog). It drove Momma crazy. And tore up my fingernails. They still won’t grow back right. Wipe all that shit off just for it to build up again. But that house was inherited and fully paid for. No reason to move. I did move. I was ready to move on. Move up. Move out. Over that small town. Into the big city. Here the streets take on the smells of Momma’s house. Plus piss, shit, and unbathed skin. A hot day means everything cooks and stews in its own juices, making the stench 10x more intense. The apartment is another story. 11 floors up. Big, east-facing windows. Great view of the skyline dotted with some green foliage. And the great lake. Immaculate. Odorless. Not even a trace of tobacco from the previous tenant’s bad habits. No lingering scent of lemon Lysol. No street stench seeping through the window panes. No stray cat hairs. Or dog fur. Not a speck of dust. Futon. Throw pillows. Photos. Knickknacks. Bowls of fresh citrus. Cursedly-assembled desk set from IKEA. Yet the void is too big to fill. Too clean. (shrink)

Research monography about the works of famous Mongolian writer, scholar B. Rinchen.

Spiritual Theology's journey through these last decades shows an itinerary of development, the fruit of which is an ever more solid identity. This book seeks to present a perspective in that itinerary and in tune with the signs of our times: on one hand, militant secularism and, on the other, a widespread, concrete resurgence of experiences of transcendence. In this sense, the author is presenting a path of study organized around five concepts: presence, mystery, transcendence, lived experience, and transformation. In (...) effect, the inner transformation worked by the Presence of Mystery leaves a new knowing, in which the relationship with reality is renewed, since it has expanded and dilated beyond sensible perception, opening the subject up to an unlimited and real horizon of transcendence. The awareness of perceiving a 'greater reality' within reality leaves an emotional resonance that teaches a new way of feeling and reacting in the face of sensibly perceived reality. (shrink)

Within any organization (e.g. a hospital or clinic) the perception of the way things operate may vary dramatically as a function of one’s location in the organizational hierarchy as well as one’s professional discipline. Interorganizational variability depends on organizational coherence, safety, and stability. In this four-nation (Canada, Ireland, Australia, and Korea) qualitative study of 42 nurses, we explored their perception of how ethical decisions are made, the nurses’ hospital role, and the extent to which their voices were heard. These nurses (...) suggested that their voices were silenced (often voluntarily) or were not expressed in terms of ethical decision making. Finally, they perceived that their approach to ethical decision making differed from physicians. (shrink)
