Health Care Ethics is another addition to the growing number of texts that attempt to provide a much-needed Canadian perspective on many of the issues that arise in the delivery of health care. The readings are divided into three parts: “The Nature and Context of Health Care Ethics”; “Decision-Making in Health Care”; and “Decisions Near the Beginning and End of Life.” Collectively, they cover a variety of different issues—pluralism and multiculturalism, resource allocation and rationing, consent, research involving human subjects, genetics, (...) abortion, assisted reproductive technologies, euthanasia, and assisted suicide. The editorial introductions to these issues, while well written, readable, and clear, are general and deliberately non-committal in assessing the different and competing approaches and arguments reflected in the selected articles in which these issues are discussed.

In lieu of an abstract, here is a brief excerpt of the content:Global Empires and The Roman ImperiumBrent D. ShawP. Fibiger Bang, C. A. Bayly, and W. Scheidel, eds. The Oxford World History of Empire. 2 vols. Oxford: Oxford University Press, 2021; xxviii + 552 pp.; xxxiv + 1,318 pp.The volumes under review are an impressive if unequal diptych. The first, the slimmer of the two, entitled "The Imperial Experience," comprises a series of analytical studies on the creation, management, and (...) ideologies of empires, and forms of resistance to them. The second, "The History of Empires," is a forbidding tome of forty-four specific studies of individual empires and imperial ventures, from Ur III and Middle Kingdom Egypt to the Mongols and the British, ending, naturally, with America's "global imperium." In the analytics, the usual suspects, including Michael Doyle, Frederick Cooper and Jane Burbank, are on display; and the conceptual approaches of Michael Mann and Ernest Gellner are favorite points d'appui. For premodern empires, the ideas of the Maghribi thinker Ibn Khaldūn provide a different focus, so it is heartening to see Bang and others applying them more consistently (e.g., 1:13, 40, 326–9; 2:162, 246–8, 253). Especially for premodern empires, these volumes can be seen as an extension of earlier handbooks devoted to the state, one devoted to the ancient Near Eastern and Mediterranean state and another on ancient empires.1 As an aspect of world history, the endeavor is the culmination of a decades-long project on the history of empires fronted by Peter Bang.2 He has usefully produced detailed historical introductions not only to both volumes, but also to the subsections in each of them. Perhaps not surprisingly, empire turns out to be a virile enterprise. As Ian Morris notes, "the story of empire... is so strongly gendered that it [End Page 505] seems reasonable to call rulers and commanders 'he' throughout" (1:162 n. 14). The muscular subject is mirrored by its principal actors and by its students. All the editors are men. Reflecting the same balance, out of the forty-five authors of individual studies in the large history of empires volume, there are five (lonely) female voices. In both volumes, women as subjects of empire are, for all intents and purposes, absent.3From the perspective of an historian who has actually worked on the history of an empire, it must be plainly stated that almost all of the theories, adequately reviewed by Bang (1:20–48), are worth about as much as the paper or pixilated screens on which they have been written. Obvious and serious exceptions to every one of the definitions and hypotheticals abound. In fact, a fair number of the exemplary histories in the second volume do not obey the strictures of most of the theories advanced in the first. So it is with a sense of relief that one turns from theory to the hard quantities offered by Walter Scheidel (1:chap. 2). To a considerable degree, his analysis depends on the well-known measurements made by Rein Taagepera. Rather alarmingly, Taagepera counted as an empire "any large sovereign political entity whose components are not sovereign," say, like the well-known empires of Algeria, Finland, or Canada.4 What an analysis of these global entities confirms is that size or orders of magnitude mattered, and that the first entities to count as empires emerged in the 7th to 5th centuries bce in southwestern Asia (1:53; 2:161, 245). The neo-Assyrian empire was the first super-large territorial state and its successor, the Achaemenid empire, was the first "hyper-power without rival" (1:172; 2:83, 111, 161). Subsequent premodern empires were able to reach higher levels of millions of square kilometers of territory and larger populations of dozens of millions of subjects nominally under their aegis. The magnitudes reached by a given generation of super-states set base-lines above which a successor might be able to reach greater sophistication of rule, numbers of subjects, and extent of territory. In some cases, being able to piggy-back on existing empires, they were able to skip early developmental stages and to advance quickly to imperial status, as a succession... (shrink)

The Platonic MS. Vat. gr. 225 contains tetr. I, VI. 3, 4, II–IV, while its companion volume in the same hand Vat. gr. 226 contains V–VI. 2, VIII. 3, VII, Spp., VIII. 1, 2. Posts states that for tetr. I and VI. 3 A is close to Vind. suppl. gr. 7 and thereafter derives from the Clarkianus . I am here concerned only with the testimony of Δ in. 2 . This manuscript has been largely ignored by commentators and editors. (...) Schanz does not quote it, nor does Bekker . Alline is scornful about it. Neither Burnet nor Croiset quotes it—and indeed Burnet claims that it is merely an interpolated apograph of W. Stallbaum seems to be the only editor who quotes it for Apol. This appears to be an unwarranted neglect since A has, in fact, a good claim to be considered as a primary witness in this dialogue. (shrink)

The notion of an algebraic semantics of a deductive system was proposed in [3], and a preliminary study was begun. The focus of [3] was the definition and investigation of algebraizable deductive systems, i.e., the deductive systems that possess an equivalent algebraic semantics. The present paper explores the more general property of possessing an algebraic semantics. While a deductive system can have at most one equivalent algebraic semantics, it may have numerous different algebraic semantics. All of these give rise to (...) an algebraic completeness theorem for the deductive system, but their algebraic properties, unlike those of equivalent algebraic semantics, need not reflect the metalogical properties of the deductive system. Many deductive systems that don't have an equivalent algebraic semantics do possess an algebraic semantics; examples of these phenomena are provided. It is shown that all extensions of a deductive system that possesses an algebraic semantics themselves possess an algebraic semantics. Necessary conditions for the existence of an algebraic semantics are given, and an example of a protoalgebraic deductive system that does not have an algebraic semantics is provided. The mono-unary deductive systems possessing an algebraic semantics are characterized. Finally, weak conditions on a deductive system are formulated that guarantee the existence of an algebraic semantics. These conditions are used to show that various classes of non-algebraizable deductive systems of modal logic, relevance logic and linear logic do possess an algebraic semantics. (shrink)

Dai Zhen’s philosophy of language took the opportunity of a transition in Chinese philosophy to develop a form of humanist positivism, which was different from both the Song and Ming dynasties’ School of Principles and the early Qing dynasty’s philosophical forms. His philosophy of language had four primary manifestations: It differentiated between “names pointing at entities and real events” and “names describing summum bonum and perfection”; In discussing the metaphysical issue of “the Dao,” it was the first to introduce a (...) syntax analysis of linguistics, clearly differentiating between the different roles of predicate verbs “zhi wei” and “wei zhi” in Classical Chinese; In criticizing Confucian thought during the Song and Ming dynasties, it adopted specific philological skills such as the analysis of phraseology, the meaning of sentences and the thread of words in texts; and It re-interpreted the meaning of Confucian classics by studying characters and language, adopting a positivist and philological manner to seek metaphysical sense in philosophy. In this way, his philosophy was different from the scholars of the School of Principles during the Song and Ming dynasties and from the goal of Western linguistic philosophy in the 20th century, which refuted metaphysics. Accordingly, it helped to develop 18th century Chinese philosophy as it turned towards linguistic philology. (shrink)

The conceptual framework and core courses of the certificate program in Preventive Engineering and Social Development of the Centre for Technology and Social Development at the University of Toronto are briefly described. Preventive approaches for the engi neering, management, and regulation of technology examine how technology fits into, interacts with, and depends on human life, society, and the biosphere in order to apply this understanding in a negative feed back mode to avoid or reduce harmful effects to these contexts. These (...) approaches represent a new paradigm for engineering education and practice enriched through STS. (shrink)

This paper contains a defense against anti-realism in mathematics in the light both of incompleteness and of the fact that mathematics is a ‘cultural artifact.’. Anti-realism (here) is the view that theorems, say, of aritltmetic cannot be taken at face value to express true propositions about the system of numbers but must be reconstrued to be about somctliiiig else or about nothing at all. A ‘bite-the-bullet’ aspect of the defease is that, adopting new axioms, liitherto independent, is not. a matter (...) of recognizing trutlis wliich had previoasly been unrecognized, but of extending the domain of what is true.

Gap junction intercellular communication channels permit the exchange of small regulatory molecules and ions between neighbouring cells and coordinate cellular activity in diverse tissue and organ systems. These channels have short half‐lives and complex assembly and degradation pathways. Much of the recent work elucidating gap junction biogenesis has featured the use of connexins (Cx), the constituent proteins of gap junctions, tagged with reporter proteins such as Green Fluorescent Protein (GFP) and has illuminated the dynamics of channel assembly in live cells (...) by high‐resolution time‐lapse microscopy. With some studies, however, there are potential short‐comings associated with the GFP chimeric protein technologies. A recent report by Gaietta et al., has highlighted the use of recombinant proteins with tetracysteine tags attached to the carboxyl terminus of Cx43, which differentially labels ‘old’ and ‘new’ connexins thus opening up new avenues for studying temporal and spatial localisation of proteins and in situ trafficking events.1 BioEssays 24:876–880, 2002. © 2002 Wiley Periodicals, Inc.
