In this paper we introduce the concept of conservative translation between logics. We present some necessary and sufficient conditions for a translation to be conservative and study some general properties of logical systems, these properties being characterized by the existence of conservative translations between the systems. We prove that the class constituted by logics and conservative translations between them determines a co-complete subcategory of the bi-complete category constituted by logics and translations.

Moral theories which, like those of Plato, Aristotle and Aquinas, give a central place to the virtues, tend to assume that as traits of character the virtues are mutually compatible so that it is possible for one and the same person to possess them all. This assumption—let us call it the compatibility thesis—does not deny the existence of painful moral dilemmas: it allows that the virtues may conflict in particular situations when considerations associated with different virtues favour incompatible courses of (...) action, but holds that these conflicts occur only at the level of individual actions. Thus while it may not always be possible to do both what would be just and what would be kind or to act both loyally and honestly, it is possible to be both a kind and a just person and to have both the virtue of loyalty and the virtue of honesty.

In debates about criteria for human death, several camps have emerged, the main two focusing on either loss of the "organism as a whole" (the mainstream view) or loss of consciousness or "personhood." Controversies also rage over the proper definition of "irreversible" in criteria for death. The situation is reminiscent of the proverbial blind men palpating an elephant; each describes the creature according to the part he can touch. Similarly, each camp grasps some aspect of the complex reality of death. (...) The personhood camp, in contrast to the mainstream "organism" camp, recognizes that a human organism can still be a biological living whole even without brain function. The mainstream camp, in contrast to the personhood camp, recognizes that a person can be permanently, even irreversibly unconscious, and still be a living person so long as his/her body is alive. The author proposes that hylomorphic dualism incorporates both these key insights. But to complete the picture of the entire "death elephant," a fundamental paradigm shift is needed to make sense of other seemingly conflicting insights. The author proposes a "semantic bisection" of the concept of death, analogous to the traditional distinction at the beginning of life between "conception" and "birth." To avoid the semantic baggage associated with the term "death," the two new death-related concepts are referred to as "passing away" (or "deceased") and "deanimation," corresponding, respectively, to sociolegal ceasing-to-be (mirror image of birth) and ontological/theological ceasing-to-be of the bodily organism (mirror image of conception). Regarding criteria, the distinguishing feature is whether the cessation of function is permanent (passing away) or irreversible (deanimation). If the "dead donor rule" were renamed the "deceased donor rule" (both acronyms felicitously being "DDR"), the ethics of organ transplantation from non–heart-beating donors could, in principle, be validly governed by the DDR, even though the donors are not yet ontologically "deanimated." Thus, the paradigm shift satisfies both those who insist on maintaining the DDR and those who claim that it has all along been receiving only lip service and should be explicitly loosened to include those who are "as good as dead." Even so, a number of practical caveats remain to be worked out for non–heart-beating protocols. (shrink)

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

Issues of resource allocationResource allocation, triageTriage, and rationingRationing decisions are common in the context of disasters and public healthPublic health emergencies, such as pandemics. However, to date, the majorityMajority of the literature focuses on an adult population with very little attention given to a pediatric population or to a population that may be mixed: adults and children. Furthermore, decisions of rationingRationing scarce resources do not only occur during disasters and other wide-scale emergencies. Such decisions are commonplace in pediatric organ transplantation (...) and can creep into areas of experimental medicine, such as xenotransplantation. This chapter explicates differences between pediatric and adult triageTriage decisions by first looking at the trifold issues of resource allocationResource allocation, triageTriage, and rationingRationing decisions mainly in the context of a disaster situation or public healthPublic health emergency. However, the issues of pediatric organ transplantation, health disparitiesHealth disparities, and experimental medicine will also be covered. (shrink)

Properties of non‐canonical GC base pairs and their relations with mechanochemical cleavage of DNA are analyzed. A hypothesis of the involvement of the transient GC wobble base pairs both in the mechanisms of the mechanochemical cleavage of DNA and epigenetic mechanisms involving of 5‐methylcytosine, is proposed. The hypothesis explains the increase in the frequency of the breaks of the sugar‐phosphate backbone of DNA after cytosines, the asymmetric character of these breaks, and an increase in break frequency in CpG after cytosine (...) methylation. As an alternative hypothesis, probable implication of GC+ Hoogsteen base pairs is considered, which now exemplify the best‐studied non‐canonical GC base pairs in the DNA double helix.

That is, Saturno Augusto sacrum. Gaius Memmius Pudens sacerdos intrauit sub iugum libens animo. Intrauit sub iugum is peculiar to this text, but it is reasonable to suppose that the plain intrauit used in other inscriptions of priests of the African Saturnus is a shorter equivalent. Professor Schulten has suggested that some symbolical act indicating the assumption of priesthood is thereby indicated. We may go a little further.

Objective: To explore the relationship between the presentation of suffering and support for euthanasia in the British news media.Method: Data was retrieved by searching the British newspaper database LexisNexis from 1996 to 2000. Twenty-nine articles covering three cases of family assisted suicide were found. Presentations of suffering were analysed employing Heidegger’s distinction between technological ordering and poetic revealing.Findings: With few exceptions, the press constructed the complex terrain of FAS as an orderly or orderable performance. This was enabled by containing the (...) contradictions of FAS through a number of journalistic strategies: treating degenerative dying as an aberrant condition, smoothing over botched attempts, locating the object of ethical evaluation in persons, not contexts, abbreviating the decision making process, constructing community consensus and marginalising opposing views.Conclusion: The findings of this study support the view that news reporting of FAS is not neutral or inconsequential. In particular, those reports presenting FAS as an orderly, rational performance were biased in favor of technical solutions by way of the legalisation of euthanasia and/or the involvement of medical professionals. In contrast, while news reports sensitive to contradiction did not necessarily oppose euthanasia, they were less inclined to overtly support technical solutions, recognising the importance of a trial to address the complexity of FAS.

Positivists have excelled at destructive criticism. This criticism has been useful for pruning away absurd and superfluous theories but it is liable to be used to prune away everything else. The latest exponents, the Logical Positivists, are no less adept at criticism than their predecessors. The doctrines of this school have been surrounded with an air of mystery and inquirers have been frightened off by alarming technical apparatus. We all know that the Logical Positivists had proved that everybody else talked (...) nonsense, but we did not know what they themselves talked. Mr. A. J. Ayer's exposition of the doctrine, Language, Truth and Logic , is therefore welcome as it is simple. (shrink)

Physicians have developed a number of implicit and explicit approaches to complex medical decisions. Decision analysis is an explicit, quantitative method of clinical decision making that involves the separation of the probabilities of events from their relative values, or utilities. Its use can help physicians make difficult choices in a manner that promotes true patient participation. Decision analysis also provides a framework for the incorporation of data from multiple sources and for the assessment of the impact of uncertain data on (...) the final decision. Although this approach is imperfect, it represents a significant advance in clinical decision making. (shrink)

This article deals with the complex relation between providence and descent in Neoplatonism, with particular reference to Proclus and especially his Commentary on the First Alcibiades. At least according to this work, descent is only a species of providence, because there can be providence without any descent. Whereas the gods provide for our cosmos without descending to it, a large group of souls provide for our cosmos by descending to it. The former kind of providence is better than the latter, (...) even if it is necessary that souls descend in order to give existence to the beautiful cosmos. The following study deals with providence as descent, looking at it from two angles. In the first section I show that Proclus designates this form of providence in two rather surprising ways. One term he uses for it, which will be well known to readers of Plotinus, is τόλµα —this despite the word’s negative connotations due to its Neopythagorean and Gnostic origin. A second name for descended providence is ἐπιστροφή. Again, this may be surprising, since we usually expect this term to express the ‘turning back’ of a lower effect to its cause. In Proclus, the word ἐπιστροφή too can have negative connotations, but he also uses it in a positive way when applying it to providence. In the second part of the paper, I explain how Socrates’ providence for Alcibiades can be undefiled, even if Socrates necessarily descends as he offers providential guidance. Proclus’ comparison of Socrates with Hercules, who went to the Underworld in order to save Theseus, serves as a positive illustration of Socrates’ divinelike providence, and marks the deficiency of Socrates compared to the transcendent and undefiled providence of Neoplatonic divinities.
