This article focusses upon defining those factors which may contribute to the pathogenesis of cancer. The molecular basis of tumour etiology is discussed with reference to cancer predisposing syndromes, and in particular to the human inherited disease, Bloom's sysdrome. In Bloom's syndrome, patients are predisposed to a wide variety of malignant disease. We propose a model in which overexpression of the ubiquitous c‐myc proto‐oncogene contributes to this process.

There are two general conceptions on the relationship between probability and logic. In the first, these systems are viewed as complementary—having offsetting strengths and weaknesses—and there exists a fusion of the two that creates a reasoning system that improves upon each. In the second, probability is viewed as an instance of logic, given some sufficiently broad formulation of it, and it is this that should inform the development of more general reasoning systems. These two conceptions are in conflict with each (...) other, where the root issue of contention is the proper abstraction of the concept of logical consequence. In this work, we put forth a proposal on this abstraction based on an extension of the subset relation through the use of projections, which in turn, allows for the formalization of valid inferences to more general settings. Our proposal results in a formalism that encompasses probability and classical logic, and importantly, does so with minimal machinery. This formalism makes assertions about the relationship between these two systems that are explicit, and suggests a path forward in the development of alternatives to them. (shrink)

It is argued that the proper way to construct and deliver a therapeutic sermon is to take a theocentric approach. Preaching, rightly understood, is proclamation of the good news that God has redeemed the world through Christ in the power of the Holy Spirit. It is by definition theological. Feeling pressure to be relevant, engaging and contemporary, a significant number of preachers fall into administering mini-doses of psychological self-help from the pulpit. Hans Urs von Balthasar’s homily, ‘Joy in the Midst (...) of Anxiety’, is offered as a positive alternative. The sermon is theologically and homiletically analysed to show why it is an excellent example of theocentric therapeutic preaching. (shrink)

Information security can be of high moral value. It can equally be used for immoral purposes and have undesirable consequences. In this paper we suggest that critical theory can facilitate a better understanding of possible ethical issues and can provide support when finding ways of addressing them. The paper argues that critical theory has intrinsic links to ethics and that it is possible to identify concepts frequently used in critical theory to pinpoint ethical concerns. Using the example of UK electronic (...) medical records the paper demonstrates that a critical lens can highlight issues that traditional ethical theories tend to overlook. These are often linked to collective issues such as social and organisational structures, which philosophical ethics with its typical focus on the individual does not tend to emphasise. The paper suggests that this insight can help in developing ways of researching and innovating responsibly in the area of information security. (shrink)

In recent years, a handful of model systems from the basal metazoan phylum Cnidaria have emerged to challenge long-held views on the evolution of animal complexity. The most-recent, and in many ways most-promising addition to this group is the starlet sea anemone, Nematostella vectensis. The remarkable amenability of this species to laboratory manipulation has already made it a productive system for exploring cnidarian development, and a proliferation of molecular and genomic tools, including the currently ongoing Nematostella genome project, further enhances (...) the promise of this species. In addition, the facility with which Nematostella populations can be investigated within their natural ecological context suggests that this model may be profitably expanded to address important questions in molecular and evolutionary ecology. In this review, we explore the traits that make Nematostella exceptionally attractive as a model organism, summarize recent research demonstrating the utility of Nematostella in several different contexts, and highlight a number of developments likely to further increase that utility in the near future.

Of the hundreds of Greek common nouns and adjectives preserved in our MSS of Cicero, about three dozen are found written in the Latin alphabet as well as in the Greek. So we find, alongside συμπάθεια, alsosympathia, and ἱστορικός as well ashistoricus.This sort of variation has been termed alphabet-switching; it has received little attention in connection with Cicero, even though it is relevant to subjects of current interest such as his bilingualism and the role of code-switching and loanwords in his (...) works. Rather than addressing these issues directly, this discussion sets out information about the way in which the words are written in our surviving MSS of Cicero and takes further some recent work on the presentation of Greek words in Latin texts. It argues that, for the most part, coherent patterns and explanations can be found in the alphabetic choices exhibited by them, or at least by the earliest of them when there is conflict in the paradosis, and that this coherence is evidence for a generally reliable transmission of Cicero's original choices. While a lack of coherence might indicate unreliable transmission, or even an indifference on Cicero's part, a consistent pattern can only really be explained as an accurate record of coherent alphabet choice made by Cicero when writing Greek words.

Our manuscripts of Cicero contain dozens of Greek words that are presented in some passages in Greek letters, and in others are transliterated into Latin. In a recent paper I collected the evidence for this phenomenon in connection with common nouns and adjectives, surveyed scholarship to date and posited an interpretative framework which is assumed in this study also. Key components of this framework are the use of mixed alphabets in surviving ancient documents and an awareness of the frequency with (...) which modern editors change the alphabets in the manuscripts when dealing with Greek words—hence the importance of using the apparatus critici, not just the printed text, of our editions. The earlier paper was also strict in its exclusion of words in continuous passages, and even short phrases, of Greek, since that context excludes the option of transliteration for the author. The major contention of that earlier study was that a coherent pattern of use in the manuscripts can only really be a reflection of Cicero's own considered choice of alphabets: consistently inexplicable choice may indicate that Cicero himself was indifferent to which alphabet he used for single Greek words, or that our copyists paid no attention to this aspect of their exemplars, or both.

The difficulty of this little poem is shown by the facts that Ausonius had no idea what it was about, and that Westendorp Boerma's commentary takes 22 pages to explicate its five lines. The latter relies on Quintilian 8.3.27ff., who quotes the poem, saying that Vergil wrote it to attack a certain Cimber for his taste in obsolete words. This is no doubt the Annius Cimber whom Augustus ridiculed when reprimanding Mark Antony for a similar foible and who, as an (...) antiquarius is contrasted with the Asiatici oratores. For convenience, I have kept Westendorp Boerma's text, but I take issue with his interpretation on two points. 4 tau Gallicum: since Bücheler tentatively suggested it in RhM 38 , 508, the standard explanation of this has been to point out that a number of Latin inscriptions in Gaul use a Greek θ or else a barred D , to represent what appears to have been a dental fricative elsewhere indicated in Latin by -sd- or -st-. Thus Frank, AJP 56 , 255, quotes HYÐRITANVS for what is elsewhere spelled Thysdritanus, and says that ‘Ð clearly represents the best that one Celt could do with sd’. On the basis of this supposed Gallic incompetence, Frank went on to see the repeated -st- sounds in the poem as some sort of joke on the orator's inability to pronounce this sound. His view seems to have been generally accepted. There seems to me a profound error in this viewpoint which shows cultural imperialism at its worst. First, let us note that none of the examples of alleged substitution are in Latin words; they are native names for people or places or things. The Latin names by which we know some of them are only the approximation of foreigners, and not in any sense the ‘correct’ names of those people or places. (shrink)

We describe the Catholic natural law tradition by examining its origins in the medieval penitentials, the papal decretals, the writings of Thomas Aquinas, and seventeenth century casuistry. Catholic natural law emerges as a flexible ethic that conceives of human nature as rational and as oriented to certain basic goods that ought to be pursued and whose pursuit is made possible by the virtues. We then identify four approaches to natural law that have evolved within the United States during the twentieth (...) century, including the traditionalist, proportionalist, right reason, and historicist approaches. The normative implications of these approaches are discussed in relation to ethical issues in the tobacco industry, ITT under Geneen, the marketing of pharmaceuticals, affirmative action, and bribery. It is argued that Alasdair MacIntyre is correct in claiming that the natural law tradition is superior to the liberal ethics of modern deontology and utilitarianism. (shrink)

In the field of business ethics, expositions of ethical theory have tended to focus on deontology and utilitarianism. More inclusive reviews of ethical theory tend to be historical and unsystematic. This paper approaches the task of representing the variety of ethical theories systematically. It does so by constructing a schema of possibilities in ethical theory which maps out six "voices", or theoretical positions, all of which are relevant and important for understanding ethics in business. This approach helps to account for (...) the continual presence of dilemmas and conflicts in ethics. (shrink)

The traditional exposition of Kantian ethical theory in the business ethics literature is abstract, esoteric, and impractical compared to the more usable presentations of utilitarianism. This situation can be improved by identifying and describing the conceptual dimensions of formalistic ethical reasoning, as contained in the interplay between case and principle, with examples from the business/society literature.

The neglected area of later Greek syntax is explored here with reference to the future optative. This form of the verb first appeared early in the classical age but virtually disappeared during the Hellenistic era. Under the influence of Atticism it reappeared in later literary texts, and this paper is concerned largely with its revival in late legal and epistolary texts on papyrus from Egypt. It is used mainly in set legal phrases of remote future conditions, but we also see (...) it in letters to express wishes (again, largely formulaic) for the future, both of which uses are foreign to Attic Greek. Finally, the future optative's appearance in conjugations on grammatical papyri from Egypt is used to demonstrate the form's presence in education even at the end of the classical world there, with the archive of Dioscorus of Aphrodito uniquely showing both this theoretical knowledge of it and examples of its application in legal documents.

Using a two-part instrument consisting of eight vignettes and twenty character traits, the study sampled 141 employees of a mid-west financial firm regarding their predispositions to prefer utilitarian or formalist forms of ethical reasoning. In contrast with earlier studies, we found that these respondents did not prefer utilitarian reasoning. Several other hypotheses were tested involving the relationship between people's preferences for certain types of solutions to issues and the forms of reasoning they use to arrive at those solutions; the nature (...) of the relationship between utilitarian and formalist categories ; and the possibility of measuring ethical predispositions using different methods.

Today''s headlines suggest that economic criteria alone is the basis for business decision-making. This paper argues that while profitability is a legitimate end of business, it must be moderated by ethical considerations. But can business be both successfuland ethical? Practical examples highlight individuals who chose profitability over ethical responsibility and those who chose and continue to choose both. The authors propose that there is an ethical person profile. Corporate managers can resolve the profits vs ethics dilemma by modeling ethical behavior.

An integration of rhetoric and method, or communication and inquiry, is important for contemporary communication research because it suggests a framework for understanding Speech Communication as an epistemological discipline. Yet, an integration of rhetoric and method is problematic. A breakdown of the understanding of invention as an epistemologically informative process of discovery has contributed to a schism of rhetoric and method. Nominalistic commitments, primarily characterized by the assumptions of British Empiricism, have led to difficulties in contemporary accounts of communication and (...) inquiry and to a view of inquiry in which rhetoric has no place. ;My aim in this study is to provide a basis for an integration of rhetoric and method with an explication of Charles Peirce's Speculative Rhetoric, or as it is also known, Methodeutic. Speculative Rhetoric is concerned with the semeiotic structure of thought--the laws governing the relations of signs with other signs--and thought is given a dialogic model by peirce. Speculative Rhetoric can thus be viewed as concerned with the semeiotic structure of communication. Speculative Rhetoric as Methodeutic also is concerned with the nature and function of inquiry, i.e., with the inferential structure of method. ;A common assumption among Peirce scholars is that little is known about Speculative Rhetoric, because Peirce did not appear to expose its concerns in any systematic way. The difficulty, however, is that Peirce had much to say about the laws governing the relations of signs with signs, and the conduct of inquiry. And, much of what Peirce said is very systematic. I explicate the interests of speculative Rhetoric by examining Peirce's account of semeiosis and his account of the method of inquiry. The account of semeiosis then provides an explication of the inferential nature of communication, while the account of inquiry provides an explication of the epistemological function of communication. The two accounts together show the integration of rhetoric and method that makes speculative Rhetoric a metatheoretical framework for communication theory, i.e., a pragmatism of communication that grounds a realist philosophy of communication.

Abstract:The main purpose of this paper is to defend traditional ethical theory (utilitarianism and deontology) for its application in business against a more recent model consisting of utility, rights, and justice. This is done in three parts: First, we provide a conceptual argument for the superiority of the traditional model; second, we demonstrate these points through an examination of three short cases; and third, we argue for the capability of the traditional model to account for universais and particulars in ethics.

The prevailing pedagogical approach in business ethics generally underestimates or even ignores the powerful influences of situational factors on ethical analysis and decision-making. This is due largely to the predominance of philosophy-oriented teaching materials. Social psychology offers relevant concepts and experiments that can broaden pedagogy to help students understand more fully the influence of situational contexts and role expectations in ethical analysis. Zimbardo's Stanford Prison Experiment is used to illustrate the relevance of social psychology experiments for business ethics instruction.

La enseñanza moral católica afirma que es necesario el consentimiento de los pacientes para autorizar las intervenciones sanitariasque les afectan, pero no especifica las condiciones para obtener dicho consentimiento o evaluar la capacidad de decisión. Aquí se presentan los artículos recogidos en este número que los autores han desarrollado a partir de las presentaciones que hicieron durante un coloquio reciente de la Asociación Internacional de Bioética Católica (IACB) celebrado en Quebec, Canadá. Contribuyen a promover el pensamiento ético sobre la capacidad (...) de toma dedecisiones y el consentimiento. De diversas formas, piden que se respete la dignidad de todos los pacientes y que se promueva su participación tanto como sea posible en la toma de decisiones sobre su salud. Consideran que la toma de decisiones es relacional y abarca una variedad de capacidades. Examinan el papel de los miembros de la familia y de otros partidarios de la toma de decisiones en la promoción de las capacidades de los pacientes, cuya condición de salud mental o discapacidad les impide a menudo cumplir con los estándares clínicos y legales típicos para la capacidad de toma de decisiones.

The growing awareness that corporate and public policy forming processes are intensively utilitarian has provoked a variety of criticism. The procedural difficulties of utilitarianism are well known; less well known but potentially more devastating is a set of charges that utilitarian policy processes intrude upon important relationships and societal processes. This paper defends utilitarian methods against these charges.More specifically, two criticisms are singled out for examination. The first is the claim that utilitarian policy processes systematically discriminate against the rights of (...) non-human life and suppress any feelings of sympathy or obligation humans might have for animals or plants. The second is the argument that utilitarianism ultimately circumvents considerations of process which are essential for the development of individual and societal identity. (shrink)
