At the beginning of the twentieth century, the Italian cytologist Paolo Della Valle developed a theory of instable chromosomes (teoria dei cromosomi labili). He radically criticized the so-called Sutton–Boveri hypothesis (Martins and Martins, Genetics and Molecular Biology, 22:261–271, 1999), focusing on numerical constancy in the species and individuality. On the basis of bibliographical review and personal observations, he maintained that the chromosomes were neither stable bodies, nor permanent structures, but transitory cellular materials, resulting from the periodical re-arrangement of the chromatin (...) during the cell division. German and English-speaking biologists reacted. The paper shows some content of the argumentations used by Thomas H. Montgomery and especially Edmund B. Wilson. The discussion was characterized by the same data which is interpreted by different scholars in different ways. And the point is that no one of them had the decisive test to demonstrate his own point of view. Wilson simply invoked on his behalf a certain ‘common sense’, defending at least a ‘high degree of constancy’. The debate waned along with the reception of Morgan’s chromosome theory of heredity, but only the advent of molecular biology definitively stated the nature of chromosomes as permanent structures of the cell.

Alasdair Maclntyre, author of After Virtue, combined moral philosophy, sociology, and history in a way that could lead scholarship in journalism and mass communication along interesting new paths. His definition of a social practice may be especially helpful by providing a model of what can happen when journalists working in close knit professional communities strive to meet standards of excellence and his articulation of the creative connection between social practice past and present offers new possibilities for writing journalism history. After (...) Virtue and other works by Maclntyre neither make rtference to journalism nor provide moral decision making schema easily exportable to professional life, yet his account of the concept and role of the virtues in western society may provide a rich analytical resource for mass media scholars. This article attempts to illustrate how. (shrink)

In summarizing key developments in the study of ethics in journalism and mass communication, problems and opportunities for the future are identified. Major activities contributing to the ethics study trend include a succession of specialized books, a journal, workshops, courses, and student writing contests. These achievements have pulled journalism ethics from the marsh of neglect to a flatland of consciousness, with a four?tiered mountain remaining to be scaled that will propel mainstream communication ethicists into the arena with a growing number (...) of critical theorists and a thrust of critical scholarship.

ABSTRACT A rereading of the American scientific literature on sex determination from 1902 to 1926 leads to a different understanding of the construction of the Mendelian‐chromosome theory after 1910. There was significant intellectual continuity, which has not been properly appreciated, underlying this scientific “revolution.” After reexamining the relationship between the ideas of key scientists, in particular Edmund B. Wilson and Thomas Hunt Morgan, I argue that, contrary to the historical literature, Wilson and Morgan did not adopt opposing (...) views on Mendelism and sex determination. Rather, each preferred a non‐Mendelian explanation of the determination of sex. Around 1910, both integrated the Mendelian and non‐Mendelian theories to create a synthetic theory. One problem was the need to avoid an overly deterministic view of sex while also accepting the validity of Mendelism. Morgan’s discovery of mutations on the X chromosome takes on different significance when set in the context of the debate about sex determination, and Calvin Bridges’s work on sex determination is better seen as a development of Morgan’s ideas, rather than a departure from them. Conclusions point to the role of synthesis within fields as a way to advance scientific theories and reflect on the relationship between synthesis and explanatory “pluralism” in biology. (shrink)

This article formulates a new approach to combating corruption in Uganda. In pursuit of this research, the author highlights the chronicity of corruption in Uganda, which is uniformly political and bureaucratic. Bureaucratic corruption takes place in service delivery and rule enforcement. It has two sides: demand-induced and supply-induced. Political corruption occurs at high levels of politics. There are 'political untouchables' and businessmen who are above the law and above institutional control mechanisms. The established institutions of checks and balances in Uganda (...) have assiduously continued to have a limited bearing on corruption. Neither coherent anti-corruption norms nor severe formal sanctions are able to dishearten certain politicians and civil servants in Uganda from the deviant behaviour of structural corruption. Corruption is a spiritual departure from the law and standard of God. It is an action conceived in the human mind and carried out by the corrupt. Therefore, corruption deterrence not only lies in sound public financial management systems but depends to a large extent on having people with positive human character in all aspects of national life. This article thus provides the framework of corruption and discusses the manifestation of political and bureaucratic corruption in Uganda. It also exegetes the biblical stance regarding corruption. Finally, it proposes a panacea for combating political and bureaucratic corruption. (shrink)

Acceptance of Augustin Fresnel's wave theory of light posed numerous questions for early nineteenth-century physicists. Among the most pressing was the problem of the properties of the luminiferous ether. Fresnel had shown that light waves were transverse. Therefore, since, among ordinary materials, only solids support transverse vibrations, there existed striking likenesses between highly tangible solids and the highly intangible ether. Accordingly, such men as Augustin-Louis Cauchy, James MacCullagh, Franz Neumann, and George Green constructed various theories of an elastic-solid ether.1 At (...) the same time, however, the disconcerting implausibilities of an all-pervasive solid provoked considerable apprehension in regard to the elastic-solid tradition. Thomas Young found the concept ‘perfectly appalling’ and argued that ‘the hypothesis [that fluids can support transverse vibrations] remains completely open for discussion, notwithstanding the apparent difficulties attending it.’2 John Herschel, probably the most important English advocate of the wave theory, regarded the concept of a solid ether as only a temporary device, useful ‘till the real truth shall be discovered.’3 Consequently, despite the accomplishments which helped to make the elastic-solid theory ‘the most celebrated special form of the wave theory’,4 there were important voices of reservation.

Quantum mechanics (QM) is a favorite area of physics to feature in “science and religion” discussions. We argue that this is at least partly because the arcane results of QM can be deployed to make big theological claims by the linguistic sleight of hand of “register switching”—sliding imperceptibly from technical into everyday language using the same vocabulary. We clarify the discussion by deploying the formal mapping of QM into classical statistical mechanics (CSM) via the mathematical device of “Wick rotation.” This (...) equivalence between QM and CSM suggests caution in claiming distinctiveness for quantum theologizing. After outlining two areas in which quantum insights nevertheless resonate with longstanding themes in theological reflection (hiddenness and visualizability), we suggest that both QM and CSM point to a theology of science in which scientists participate in the divine gaze on creation as imago Dei.

With his third book on Peirce in fewer than eight years, Richard Atkins has quickly established himself as a scholar who contributes high-quality, focused, and detailed accounts of diverse areas of Peirce's thought. His first book on Peirce, Peirce and the Conduct of Life (2016), focuses on ethics and religion, while the focus of his second, Charles S. Peirce's Phenomenology (2018), is evident from the title. Now, Peirce on Inference: Validity, Strength, and the Community of Inquirers (2023) is a detailed (...) analysis of key parts of Peirce's logic—mainly the part of logic he called Critic, "which classifies arguments and determines the validity and degree of force of each kind" (EP 2:260). Perhaps what is remarkable... Read More. (shrink)

Idealist and Strong Empiricist approaches to Peirce’s thought are irreconcilable so far as an Idealist interpretation commits Peirce to some form of a priori knowledge, particularly a priori knowledge of the conditions of empirical knowledge. However, while I favor the strong empiricist approach, I agree that there is something like a “condition for the possibility of empirical knowledge” in Peirce, and that this lies with his famous conjecture that, with enough time and experience, there would be a “final result” of (...) all inquiry – “the Final Opinion.” Though some argue that this is mainly a regulative assumption or intellectual hope in Peirce, I contend that he is committed to it as an empirical hypothesis which we should provisionally accept. As an empirical hypothesis, it is not a transcendental constraint on knowledge, though it can be considered a transcendental feature (following Sacks’ (1997) distinction). That is, the thesis explains how knowledge is possible, but the epistemic status of the thesis itself is dependent on the course of experience. Here I explain how it is an empirical thesis and I explain the empirical considerations Peirce thinks support it. Though Peirce should not be considered a transcendental idealist in any robust sense, I give reasons for why he could still be considered a sort of absolute idealist. (shrink)

Virtue theorists have recently been focusing on the important question of how virtues are developed, and doing so in a way that is informed by empirical research from psychology. However, almost all of this recent work has dealt exclusively with the moral virtues. In this paper, we present three empirically-informed accounts of how virtues can be developed, and we assess the merits of these accounts when applied specifically to intellectual (or epistemic) virtues.

Short’s assertion that Peirce lacked a cohesive philosophical system is critically examined, and the interconnectedness of Peirce’s 1884–1893 “cosmology” with other aspects of his work is explored, countering Short’s claims of its limited systematic relevance. Additionally, Short’s claim that Peirce “expanded empiricism empirically” is scrutinized, and his interpretation of Peirce’s account of perception is criticized. By contrasting Short’s anti-system reading, I highlight the importance of studying Peirce’s philosophy holistically.

Background To describe the preferences for disclosure of individual biomarker results among mothers participating in a longitudinal birth cohort. Methods We surveyed 343 mothers that participated in the Health Outcomes and Measures of the Environment Study about their biomarker disclosure preferences. Participants were told that the study was measuring pesticide metabolites in their biological specimens, and that the health effects of these low levels of exposure are unknown. Participants were asked whether they wanted to receive their results and their child's (...) results. In addition, they were asked about their preferred method (letter vs in person) and format (more complex vs less complex) for disclosure of results. Results Almost all of the study participants wanted to receive their individual results (340/343) as well as their child's results (342/343). However, preferences for receiving results differed by education level. Mothers with less than a college degree preferred in-person disclosure of results more often than mothers with some college education or a college degree (34.3% vs 17.4% vs 7.9%, p<0.001). Similarly, mothers with less than a college education preferred a less complex disclosure format than mothers with some college education or a college degree (59.7% vs 79.1% vs 86.3%, p<0.0001). Conclusion While almost all study participants preferred to receive results of their individual biomarker tests, level of education was a key factor in predicting preferences for disclosure of biomarker results. To ensure effective communication of this information, disclosure of biomarker results should be tailored to the education level of the study participants. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Peirce on Realism and Idealism by Robert LaneAaron B. WilsonPeirce on Realism and Idealism Robert Lane. Cambridge UP, 2018.Robert Lane's Peirce on Realism and Idealism is the ultimate secondary source for those who wish to engage the forms of realism and idealism that Peirce develops over the course of his writings. Lane could not have given his monograph a more concise and descriptive title. He never strays from (...) the topics of realism and idealism, and it is remarkably complete. It includes extensive discussion on Peirce's basic realism (Lane's term) as well as his extreme scholastic realism (Peirce's term), his basic idealism (Lane's term), and his objective idealism (Peirce's term). It might not be the best resource for those interested in the historical influences on Peirce's forms of realism and idealism. For instance, if one is interested mainly in Peirce's extreme scholastic realism and its roots in scholastic philosophy, Mayorga (2007)1 might still be a more useful resource. Also, Lane leaves much to be said about the epistemological underpinnings of Peirce's forms of realism and idealism. Peirce's theory of perception and his critical common-sensism do not get much attention. Also, there is much in Peirce's later semeiotic writings that could have been brought to bear on the issues.However, I do not see any of these omissions as failures of Lane's work. As I read it, the book's central aims are to determine the following: (1) what metaphysical views did Peirce hold, (2) when did he hold them, (3) are they consistent with one another, and (4) what is the textual evidence that he held them as such. With respect to these aims, Peirce on Realism and Idealism exhibits the gold standard of Peirce scholarship: it is remarkably sensitive to dates, different writings, and contexts of writings, and the reader gets a strong impression that Lane has not left any stone unturned—that he had at least skimmed every word in every lecture, published writing, letter, and unpublished manuscript that Peirce produced.Although the book contains some interpretations about which I have some reservations, which I describe further on, I agree with most of its central claims. This includes the claim that, despite various developments, Peirce had always subscribed to "basic realism": the thesis that there are things independent of what anyone thinks about them. A whole chapter is dedicated to showing that Peirce's 1868–1869 "anti-Cartesian" papers are consistent with basic realism, and I found that chapter very helpful. Another thesis that Lane defends, and that I strongly agree with, is that Peirce held a representationalist view of truth. Truth as "correspondence" with reality is one of two [End Page 107] key aspects of Peirce's account of truth (the other being, as Lane calls it, an "investigative aspect"). After works by Christopher Hookway, Cheryl Misak, and others that attempt to de-emphasize or obscure Peirce's representationalism, perhaps to make him more appealing to contemporary analytic "neopragmatists," it is absolutely refreshing to read a book that embraces Peirce's representationalism without apology.However, in the remainder of this review, I will focus on parts that I found troubling. Some of this trouble is probably due more to Peirce himself than to Lane's interpretation of Peirce. But some of it directly concerns Lane's interpretation. In particular, the parts of chapter 6 concerning Peirce's modal realism, while stimulating and enlightening, are also problematic. Further, I do not think that Lane's account of Peirce's idealism appropriately recognizes its similarity to Hegelian or Absolute idealism.To begin with Peirce's modal realism, Lane's discussion of it sets out by addressing the fact that, as Peirce recognizes, the conditionals comprising "pragmatic clarifications," or what result from applying the "pragmatic maxim" to a concept, must be in the hypothetical or subjunctive mood. This is in order to make sense of the truth of even indicative non-conditional propositions such as, to use Peirce's and Lane's example, "the diamond is hard." If the conditionals into which a concept is pragmatically clarified are in the indicative mood... (shrink)
