While outcomes for children with T-cell acute lymphoblastic leukemia have improved dramatically, survival rates for patients with relapsed/refractory disease remain dismal. Prior studies indicate that glucocorticoid resistance is more common than resistance to other chemotherapies at relapse. In addition, failure to clear peripheral blasts during a prednisone prophase correlates with an elevated risk of relapse in newly diagnosed patients. Here we show that intrinsic GC resistance is present at diagnosis in early thymic precursor T-ALLs as well as in a subset (...) of non-ETP T-ALLs. GC-resistant non-ETP T-ALLs are characterized by strong induction of JAK/STAT signaling in response to interleukin-7 stimulation. Removing IL7 or inhibiting JAK/STAT signaling sensitizes these T-ALLs, and a subset of ETP T-ALLs, to GCs. The combination of the GC dexamethasone and the JAK1/2 inhibitor ruxolitinib altered the balance between pro- and anti-apoptotic factors in samples with IL7-dependent GC resistance, but not in samples with IL7-independent GC resistance. Together, these data suggest that the addition of ruxolitinib or other inhibitors of IL7 receptor/JAK/STAT signaling may enhance the efficacy of GCs in a biologically defined subset of T-ALL.Leukemia advance online publication, 30 May 2017; doi:10.1038/leu.2017.136.

People across the world seek out beautiful sounds in nature, such as a babbling brook or a nightingale song, for positive human experiences. However, it is unclear whether this positive aesthetic response is driven by a preference for the perceptual features typical of nature sounds versus a higher‐order association of nature with beauty. To test these hypotheses, participants provided aesthetic judgments for nature and urban soundscapes that varied on ease of recognition. Results demonstrated that the aesthetic preference for nature soundscapes (...) was eliminated for the sounds hardest to recognize, and moreover the relationship between aesthetic ratings and several measured acoustic features significantly changed as a function of recognition. In a follow‐up experiment, requiring participants to classify these difficult‐to‐identify sounds into nature or urban categories resulted in a robust preference for nature sounds and a relationship between aesthetic ratings and our measured acoustic features that was more typical of easy‐to‐identify sounds. This pattern of results was replicated with computer‐generated artificial noises, which acoustically shared properties with the nature and urban soundscapes but by definition did not come from these environments. Taken together, these results support the conclusion that the recognition of a sound as either natural or urban dynamically organizes the relationship between aesthetic preference and perceptual features and that these preferences are not inherent to the acoustic features. Implications for nature's role in cognitive and affective restoration are discussed. (shrink)

Up till now, China has not enacted any legal mechanisms governing certification or supervision for ethics committees. This article analyses deficiencies in the protection of subjects in clinical drug trials under China’s current laws and regulations; it emphasizes that investigators, as practitioners who have direct contact with subjects, play significant roles in protecting and safeguarding subjects’ rights and interests. The paper compares the status quo in China in this area to that of other countries and discusses ways China might enhance (...) the protection of rights and interests of trial subjects, such as enhancing the ethical awareness of investigators through training, improving laws and regulations, and strengthening the communication between investigators and ethics committees.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.3 (2003) 207-222 [Access article in PDF] Burke Contra Kierkegaard:Kenneth Burke's Dialectic via Reading Søren Kierkegaard G. L. Ercolini Isaac—to his children Lived to tell the tale— Moral—with a Mastiff Manners may prevail. —Emily Dickinson Kenneth Burke employs the term dialectic throughout his works and yet, despite its profuse recurrence, the term remains ambiguous. Much secondary scholarship has focused on Burke and dialectics, and still the (...) term in Burke remains—if not already complicated—cloudy. 1 Part of the difficulty regarding this term stems from Burke's own ambiguity; another part from critics' tendency to rely on Burke's own use and definitions for clarification of this concept. The arguments have been helpful and illuminating, yet Burke's dialectic can be further clarified by going beyond what Burke means by the term by focusing on how he deploys dialectical criticism in his own work. 2 This article focuses on Burke's appropriation of the existential thinker Søren Kierkegaard as a particularly clear and remarkable instance of the operation of Burke's dialectic in his criticism. I maintain that although Burke's reading of Kierkegaard is arguably a misreading, his strategic appropriation of Kierkegaard in A Rhetoric of Motives (1950) not only serves as a clear deployment of the dialectic, but also functions as a foil against which Burke defines his own critical method. Burke's reading of Kierkegaard emphasizes the function of resolution in Burke's critical project.The current literature, although quite informative, does not put Burke's dialectic in sharp focus. Rueckert argues that Burkean dialectics "is really a branch of what Burke was to later call logology, the study of words, of language, of symbol systems" (1994, 14). Heath claims that dialectic "is an analytical tool to help us diagnose perspectives so that we can [End Page 207] examine whether they make sense and consider their implications for social relations" (1986, 162). Crusius contends that, "dialectic for Burke is the study of verbal universes, the disinterested pursuit of a vocabulary's implications" (1986, 24). While Brummett and Crusius show similarity between Hegel's and Burke's dialectic, Heath and Wess distinguish Burke's dialectic from Hegelian idealism and teleological history respectively. 3 Most of the arguments concerning Burke and dialectic focus on "The Dialectic of Constitutions" in A Grammar of Motives (1969), while A Rhetoric of Motives (1962), where Burke identifies humankind as homo dialecticus, is hardly engaged with regard to this concept. 4 Burke's working through Kierkegaard in A Rhetoric of Motives demonstrates Burke's dialectical criticism—thus providing an operational account of Burke's dialectic—and allows for his revelation of the three motives in the realm of rhetoric: the Order, the Secret, and the Kill. 5 And yet, despite this centrality of Fear and Trembling, surprisingly little has been said about Burke's Kierkegaard beyond passing mention. 6Despite editorial advice to the opposite regarding an article that would later become a part of the book, Burke evidently regarded his reading of Kierkegaard as important. Joseph Bennett, editor of Hudson Review, responded as follows to Burke's 1948 submission of the article entitled "Imagery of Killing": "I would like to request that you eliminate Kierkegaard from the article in question, confining it simply to literary exegesis and excluding the philosopher theologian." 7 Although he complied for the article, Burke retained his reading of Kierkegaard in A Rhetoric of Motives. Despite the lack of attention given to it, Burke's engagement with Kierkegaard clearly demonstrates how Burke views ethical criticism as that which resolves opposition, negation, and paradox to a higher order. Burke contra Kierkegaard The section entitled "Order" in A Rhetoric of Motives contains a detailed, twenty-three-page discussion of Kierkegaard's Fear and Trembling. In this discussion, Burke primarily attacks Kierkegaard for encouraging what Burke enigmatically and elliptically identifies as the "cult of the Kill."Burke's portrayal of Kierkegaard is hardly flattering: at the crescendo of his analysis in A Rhetoric of Motives he claims that thinking such as Kierkegaard...

For Hannah Arendt, the promise serves as currency in a world where predictability of outcome in the realm of human action is impossible, where courage is required in order to submit oneself in word and deed in the public realm, and where forgiveness serves as recourse when things go differently than hoped. Each of these points in Arendt's political philosophy is indebted to Immanuel Kant, a thinker who is often characterized as rejecting rhetoric on aesthetic and moral grounds alike. In (...) Kant and the Promise of Rhetoric, Scott Stroud takes up the apparently straightforward but ultimately complicated question of Immanuel Kant's treatment of, and disposition toward, rhetoric.While Kant is typically characterized as...

A highly original reading of Immanuel Kant that demonstrates his interest in the social realm of human interaction.

A function is recursive (in given operations) if its values are computed explicitly and uniformly in terms of other "previously computed" values of itself and (perhaps) other "simultaneously computed" recursive functions. Here, "explicitly" includes definition by cases. We investigate those recursive functions on the structure $\mathbf{N} = \langle \omega, 0, \operatorname{succ,pred}\rangle$ that are computed in terms of themselves only, without other simultaneously computed recursive functions.

Background:The Taiwan Nursing Accreditation Council has proposed eight core professional nursing qualities including ethical literacy. Consequently, nursing ethics education is a required course for student nurses. These courses are intended to improve the ethical literacy. Moral sensitivity is the cornerstone of ethical literacy, and learning moral sensitivity is the initial step towards developing ethical literacy.Objectives:To explore the effect of nursing ethics educational interventions based on multiple teaching strategies on student nurses moral sensitivity. Based on the visual, auditory and kinaesthetic model, (...) three strategies were developed for determining the programme components and corresponding learning styles.Research design:This was a quasi-experimental study.Participants:A total of 234 junior-college student nurses participated in this study. All participants were aged 18–19 years.Ethical considerations:The study protocol was approved by the institutional review boards of Kaohsiung Veterans General Hospital. Only the participants who signed an informed consent form took part in the study. The participants were permitted to withdraw from the study at any point if they wished to do so without affecting their academic score.Results:The scores of Modified Moral Sensitivity Questionnaire for Student Nurses were significantly improved after the intervention of integrating multiple teaching strategies. Significant relationships were observed between the satisfaction scores of two teaching strategies and moral sensitivity. The results indicated that using multiple teaching strategies is effective for promoting nursing ethics learning.Conclusion:This strategy was consistent with the student nurses’ preferred learning style and was used to correct their erroneous ethical conceptions, assisting in developing their ethical knowledge.

From the materialist stance that I find compelling, the metaproblem of consciousness -- explaining why the problem of consciousness seems hard -- is hardly distinct from the 'easy' problem of explaining how the underlying physical/computational system works, and how it gives rise to perceptions of its own functioning. I discuss several confusions that might plausibly arise in that process, and propose that these confusions could create apparent gaps, ontological and epistemic, in materialist accounts of consciousness, thereby making the hard problem (...) hard. Inversely, resolving these confusions may help solve the hard problem. (shrink)
