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)

Over the past several decades, medical ethics has gained a solid foothold in medical education and is now a required course in most medical schools. Although the field of medical ethics is by nature eclectic, moral philosophy has played a dominant role in defining both the content of what is taught and the methodology for reasoning about ethical dilemmas. Most educators largely rely on the case‐based method for teaching ethics, grounding the ethical reasoning in an amalgam of theories drawn from (...) moral philosophy, including consequentialism, deontology, and principlism.In this article we hope to make a case for augmenting the focus of education in medical ethics. We propose complementing the traditional approach to medical ethics with a more embedded approach, one that has been described by others as “microethics,” the ethics of everyday clinical practice.

White matter tracts are known to be susceptible to injury following concussion. The objective of this study was to determine whether contact play in sport could alter white matter metabolite levels in female varsity athletes independent of changes induced by long-term exercise. Metabolite levels were measured by single voxel proton magnetic resonance spectroscopy in the prefrontal white matter at the beginning and end of season in contact and non-contact varsity athletes. Sedentary women were scanned once, at a time equivalent to (...) the Off-Season time point. Metabolite levels in non-contact athletes did not change over a season of play, or differ from age matched sedentary women except that non-contact athletes had a slightly lower myo-inositol level. The contact athletes had lower levels of myo-inositol and glutamate, and higher levels of glutamine compared to both sedentary women and non-contact athletes. Lower levels of myo-inositol in non-contact athletes compared to sedentary women indicates long-term exercise may alter glial cell profiles in these athletes. The metabolite differences observed between contact and non-contact athletes suggest that non-contact athletes should not be used as controls in studies of concussion in high-impact sports because repetitive impacts from physical contact can alter white matter metabolite level profiles. It is imperative to use athletes engaged in the same contact sport as controls to ensure a matched metabolite profile at baseline. (shrink)

Are we to restore ‘sit on eggs’ after Hesychius or ‘cry ’, ‘lament’ after Nauck? In his recent supplement to the Loeb Aeschylus, Mr. Lloyd-Jones says that the latter ‘is far better suited to the context’, by which I am given to understand that he means that Aeschylus would have been very unlikely to employ the brooding metaphor in this passage. Admonished by Wilamowitz that ‘es unverzeihlich ist, das Bild der briitenden Henne zu vertreiben’, I fall back in some bewilderment (...) on the fact that I personally like it very much and that the tomb-nest symbolism, though not absolutely presupposed by Cho. 247 ff. and 501(), would certainly have encouraged the poet to write these later passages. But there is a dearth of objective argument on this matter which I want, if possible, to supply. (shrink)

Down to the present century the Niobe of Aeschylus was represented by eight significant manuscript fragments containing some twenty-three lines. Even in this condition it deservedly attracted the interest and attention of scholars; and in 1933 this interest was intensified by the publication in Florence by Vitelli and Norsa of a mutilated papyrus of twenty-one lines embodying two of the earlier fragments.

Commentators from the Old Scholiast onward extract from these two clauses the one meaning that the pedagogue will not be recognized. They complain that a man's hair going white does not suffice to disguise him, and offer some unconvincing reinterpretations and emendations of The change of mood and tense is also odd; at O.C. 450 ff. which Jebb quotes in support, there is a change of meaning and intensity to justify it.

Despite its preeminent position in the just war tradition, the concept of proportionality is not well understood by military leaders. Especially lacking is a realization that there are four distinct types of proportionality. In determining whether a particular resort to war is just, national leaders must consider the proportionality of the conflict, i.e., balance the expected gain or just redress against the total harm likely to be inflicted by the impending armed action. This proportionality consideration is called jus ad bellum (...) proportionality. The second type of proportionality discussed is a continuing re-evaluation of the proportionality, taking into account the changing situation. The last true proportionality discussed is a consideration of hostile action taking during a conflict, or jus in bello proportionality. This consideration weighs the expected military gain of a particular action against the collateral damage and injuries that are expected from the act. Finally, the fourth category addressed is ‘political proportionality’, which is not a true proportionality consideration, but is rather self-interested deliberation on the possible political and military outcomes of actions. In some instances, it could be referred to as a measured response. A better understanding of proportionality in all its forms will help military leaders to give appropriate and moral advice on the potential resort to war, as well as on the conduct of military actions in war. The recent US war with Iraq in the spring of 2003 in defiance of the wishes of the majority of the UN Security Council, and especially with the potential for high noncombatant casualties in Baghdad, makes a discussion of the proper conduct of war even more poignant.

Building on the advances made by feminist reconsiderations of methods, methodology and epistemology, this paper calls for an alliance between feminist social science and the emerging field of queer theory. By challenging traditional scientific approaches to research on sexual minority groups, a distinctly ‘queer’ approach is advocated that adopts a reflexive position on subjectivity and sexuality. While essentialist approaches privilege gay/lesbian, man/woman, and object/subject, this approach advances a framework of critical sexualities that moves social science into an arena of inclusivity (...) and multiple identities, rather than reductionistic categorical thought. The implications are clear: a rethinking of identity categories that transcend stagnant dualisms. (shrink)

Bertrand Russell undertook an extended North American lecture tour in 1931 to raise funds for the Beacon Hill experimental school he operated with Dora Russell. To rectify the existing lack of scholarly analysis of the 1931 tour, this paper provides annotated transcriptions of twenty-eight letters Russell sent during the tour to Dora and to Patricia Spence, Russell’s mistress. These letters provide intriguing insights into the state of Russell’s financial and professional affairs and illuminate personal relationships he cultivated in the United (...) States and Canada. Most importantly, they document his complex marital situation at this tumultuous juncture in his life before he decided to end his relationship with Dora early in 1932 in favour of Spence. (shrink)

An implicit goal of many interventions intended to enhance integrity is to minimize peoples' exposure to unethical events. The intent of the present effort was to examine if exposure to unethical practices in the course of one's work is related to ethical decision making. Accordingly, 248 doctoral students in the biological, health, and social sciences were asked to complete a field appropriate measure of ethical decision making. In addition, they were asked to complete measures examining the perceived acceptability of unethical (...) events and a measure examining perceptions of ethical climate. When these criterion measures were correlated with a measure examining the frequency with which they had been exposed to unethical events in their day-to-day work, it was found that event exposure was strongly related to ethical decision making but less strongly related to climate perceptions and perceptions of event acceptability. However, these relationships were moderated by level of experience. The implications of these findings for practices intended to improve ethics are discussed. (shrink)

_Black Intellectual Thought in Education_ celebrates the exceptional academic contributions of African-American education scholars Anna Julia Cooper, Carter G. Woodson, and Alain Leroy Locke to the causes of social science, education, and democracy in America. By focusing on the lives and projects of these three figures specifically, it offers a powerful counter-narrative to the dominant, established discourse in education and critical social theory--helping to better serve the population that critical theory seeks to advocate. Rather than attempting to "rescue" a few (...) African American scholars from obscurity or marginalization, this powerful volume instead highlights ideas that must be probed and critically examined in order to deal with prevailing contemporary educational issues. Cooper, Woodson, and Locke’s history of engagement with race, democracy, education, gender and life is a dynamic, demanding, and authentic narrative for those engaged with these important issues.

Background: Since the passage of the Patient Self-Determination Act, numerous policy mandates and institutional measures have been implemented. It is unknown to what extent those measures have affected end-of-life care, particularly with regard to the do-not-resuscitate order.Methods: Retrospective cohort study to assess associations of the frequency and timing of DNR orders with advance directive status, patient demographics, physician’s specialty and extent of documentation of discussion on end-of-life care.Results: DNR orders were more frequent for patients on a medical service than on (...) a surgical service and were made earlier in the hospital stay for medicine than for surgical patients . 22.18% of all patients had some form of an advance directive in their chart, yet this variable had no impact on the frequency or timing of DNR ordering. Documentation of DNR discussion was significantly associated with the frequency of DNR orders and the time from DNR to death .Conclusions: The physician’s specialty continues to have a significant impact on the frequency and timing of DNR orders, while advance directive status still has no measurable impact. Additionally, documentation of end-of-life discussions is significantly associated with varying DNR ordering rates and timing. (shrink)

Ethical decision making measures are widely applied as the principal dependent variable used in studies of research integrity. However, evidence bearing on the internal and external validity of these measures is not available. In this study, ethical decision making measures were administered to 102 graduate students in the biological, health, and social sciences, along with measures examining exposure to ethical breaches and the severity of punishments recommended. The ethical decision making measure was found to be related to exposure to ethical (...) events and the severity of punishments awarded. The implications of these findings for the application of ethical decision making measures are discussed. (shrink)
