Candrakīrti is known for his commentaries on the major works of Nāgārjuna and Āryadeva. This chapter examines how Candrakīrti uses language and logic to undermine people's confidence in cherished beliefs about a self and point them towards the Buddha's path and its goal the peace of nirvana that transcends the limitations of language and logic. Candrakīrti first sets out his view on the two truths in the Madhyamakāvatāra. He associates both truths with the soteriological goal of Nāgārjuna's path: the peaceful (...) state of nirvana. Madhyamaka teaching amounts to nihilism. Candrakīrti responds that the charge of nihilism is wrong because there is no repudiation of moral actions. Emptiness is also related to the concept of intrinsic nature, and Candrakīrti uses this term in more than one sense. (shrink)

Let R be a real closed field.

Mourgues and Ressayre (J Symb Logic 58:641–647, 1993) showed that every real closed field has an integer part. The procedure of Mourgues and (...) Ressayre appears to be quite complicated. We would like to know whether there is a simple procedure, yielding an integer part that is \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\Delta^0_2(R)}$$\end{document} —limit computable relative to R.

However, this I may not be an integer part for R. By a result of Wilkie (Logic Colloquium ’77), any Z-ring can be extended to an integer part for some real closed field. Using Wilkie’s ideas, we produce a real closed field R with a Z-ring \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${I \subseteq R}$$\end{document} such that I does not extend to an integer part for R.

Most psychological literature on gaslighting focuses on it as a dyadic phenomenon occurring primarily in marriage and family relationships. In my analysis, I will extend recent fruitful philosophical engagement with gaslighting by arguing that gaslighting, particularly gaslighting that occurs in more public spaces like the workplace, relies upon external reinforcement for its success. I will ground this study in an analysis of the film Gaslight, for which the phenomenon is named, and in the course of the analysis will focus on (...) a paradox of this kind of gaslighting: it wreaks significant epistemic and moral damages largely through small, often invisible actions that have power through their accumulation and reinforcement.

This dissertation is an attempt to loosen what I see as a chokehold by which two paramount assumptions constrict our epistemic endeavors. These Enlightenment assumptions--that we accept or refute ideas as true based on transparently clear and orderly methods and criteria, and that individuals accept or refute truth claims--are still central in epistemology, despite their many critics . Thinking about gossip as an epistemologically productive concept provides us with the means to critique those assumptions, and further attempts to broaden our (...) notion of an epistemological foundation. ;Gossip at first appears to be an unlikely candidate for such a resurrection, mainly because its treatment by academics has been dismissive; this dismissal is in part due to Enlightenment conceptions about truth and falsehood. Chapter One surveys the social science literature on gossip and rumor, revealing that social scientists begin with such restrictive definitions of what gossip is that their conclusions amount to little more than tautology. Chapter Two shows that humanists have a slightly different approach to gossip, but with roughly similar results. ;The handful of philosophers who deal directly with gossip or rumor almost as a unit accept uncritically a division between "purposive" conversation and "idle" chatter. To do so, I think, perpetuates a limiting epistemic foundation on a linguistic level. In contrast, I argue in Chapter Three that the very existence of something like gossip proves the inadequacy of the foundationalist myth , and that to attempt to understand and use gossip with foundationalist tools is simply a wrong fit. My understanding of gossip is based on this central fact: we undertake the activity of gossip or rumor-spreading because we are trying to make sense out of something--we need to collect knowledge socially. Gossip originates from dissonance; it acts as a counterweight to more official information, and can't be considered apart from official knowledge. We use gossip and rumor, along with more orthodox sources of information, to formulate our understanding of ourselves and the world around us. The extent to which gossip and rumor are spread is the extent to which the analysis is shared, and not individualized. Gossip is both a genealogical tool and an speculative tool. (shrink)

Widespread concerns about the long-term fiscal gap in Social Security have prompted various proposals for structural reform, with individual accounts as the centerpiece. Carving out individual accounts from the existing system would shift significant risks and responsibilities to individual workers. A parallel development has already occurred in the area of private pensions. Experience with 401 plans indicates that many workers will have difficulty making prudent decisions concerning investment and withdrawal of funds. Moreover, in implementing any system of voluntary individual accounts, (...) it will be important to design default settings that provide appropriate guidance for workers with heterogeneous levels of financial sophistication and risk tolerance. The central goal of Social Security reform should be to close the fiscal gap in a way that preserves rather than undermines the existing system of mandatory defined benefits for all workers.

A striking and unexplained feature of granulomatous inflammation is its anatomical association with the lymphatic system. Accumulating evidence suggests that lymphatic tracks and granulomas may alter the function of each other. The formation of new lymphatics, or lymphangiogenesis, is an adaptive response to tumor formation, infection, and wound healing. Granulomas also may induce lymphangiogenesis which, through a variety of mechanisms, could contribute to disease outcomes in tuberculosis and sarcoidosis. On the other hand, alterations in lymph node function and lymphatic draining (...) may be primary events which attenuate the risk and severity of granulomatous inflammation. This review begins with an introduction of granulomatous inflammation and the lymphatic system. A role of the lymphatic system in tuberculosis and sarcoidosis is then hypothesized. With a focus on lymphangiogenesis in these diseases, and on the potential for this process to promote dissemination, parallels are established with the well‐established role of lymphangiogenesis in tumor biology.

Physicians and medical institutions in the United States are placing increasing emphasis on providing culturally sensitive care for patients, such as implementing a Confucian family-based model of medical decision making when caring for elderly Chinese patients. In this article, I articulate various reasons why deferring to the family is not a guarantee of culturally sensitive care, particularly when family members are first-generation Chinese-Americans. Nonetheless, I offer several suggestions to help physicians, medical institutions, and family members to provide more culturally sensitive (...) care for elderly Chinese patients. (shrink)

The purpose of this paper is to apply Aristotle''s theory of causation to the administrative realm in an attempt to provide the manager/student with a more complete basis for organizational analysis. The authors argue that the traditional approach to administrative case studies limits the manager''s/student''s perspective to the positivistic world view at the expense of a more encompassing perspective which can be achieved through the use of an Aristotelian approach. Aristotle''s four-part theory of causation is juxtaposed with contemporary views of (...) organizational ideology/philosophy, culture, climate and leadership, and staff or personnel. The Mazda automobile plant in Flat Rock, Michigan is provided as a sample case study to demonstrate the comprehensiveness of the Aristotelian method in organizational contexts. (shrink)

_Concepts of Philosophy_ challenges received conceptions of philosophy by way of critical engagement with Chinese and Japanese sources. Built on philologically sound readings of specific texts, the book lifts the discussion on the concept of philosophy to a global plane.

Skin pigment pattern formation is a paradigmatic example of pattern formation. In zebrafish, the adult body stripes are generated by coordinated rearrangement of three distinct pigment cell‐types, black melanocytes, shiny iridophores and yellow xanthophores. A stem cell origin of melanocytes and iridophores has been proposed although the potency of those stem cells has remained unclear. Xanthophores, however, seemed to originate predominantly from proliferation of embryonic xanthophores. Now, data from Singh et al. shows that all three cell‐types derive from shared stem (...) cells, and that these cells generate peripheral neural cell‐types too. Furthermore, clonal compositions are best explained by a progressive fate restriction model generating the individual cell‐types. The numbers of adult pigment stem cells associated with the dorsal root ganglia remain low, but progenitor numbers increase significantly during larval development up to metamorphosis, likely via production of partially restricted progenitors on the spinal nerves.

Sir Ernst Gombrich and the Barber from Tuscany In the spirit of Sir Ernst Gombrich, this essay uses an anecdote—a chat between Gombrich and a barber from Tuscany—to illustrate a deeper point, namely, how cultural memory, tradition, and a canon give rise to an implied language of culture and cultural value. Gombrich staunchly defended tradition against relativism. By relativism, he meant something like "radical subjectivism." To his mind, subjectivism (in the cultural and social sense of the term) is not only (...) impossible, since meaning is conferred through culture and society, but it is also dangerous (in the cultural and ethical sense of the term), since it denies the existence of shared values. Against consensus on the one hand and radical subjectivism on the other, Gombrich advocated a middle way: criticism and self-criticism to ensure latitude; the search for "truth" to ensure a limited plurality of interpretations.

In the last five years there have been a number of results about the computable content of the prime, saturated, or homogeneous models of a complete decidable theory T in the spirit of Vaught's "Denumerable models of complete theories" combined with computability methods for degrees d ≤ 0′. First we recast older results by Goncharov, Peretyat'kin, and Millar in a more modern framework which we then apply. Then we survey recent results by Lange, "The degree spectra of homogeneous models," which (...) generalize the older results and which include positive results on when a certain homogeneous model of T has an isomorphic copy of a given Turing degree. We then survey Lange's "A characterization of the 0-basis homogeneous bounding degrees" for negative results about when does not have such copies, generalizing negative results by Goncharov, Peretyat'kin, and Millar. Finally, we explain recent results by Csima, Harizanov, Hirschfeldt, and Soare, "Bounding homogeneous models," about degrees d that are homogeneous bounding and explain their relation to the PA degrees.

Thousands of youth suffering from acquired brain injury or other early-life neurological disease live, mature, and learn with only limited communication and interaction with their world. Such cognitively capable children are ideal candidates for brain-computer interfaces. While BCI systems are rapidly evolving, a fundamental gap exists between technological innovators and the patients and families who stand to benefit. Forays into translating BCI systems to children in recent years have revealed that kids can learn to operate simple BCI with proficiency akin (...) to adults. BCI could bring significant boons to the lives of many children with severe physical impairment, supporting their complex physical and social needs. However, children have been neglected in BCI research and a collaborative BCI research community is required to unite and push pediatric BCI development forward. To this end, the pediatric BCI Canada collaborative network was formed, under a unified goal to cooperatively drive forward pediatric BCI innovation and impact. This article reflects on the topics and discussions raised in the foundational BCI-CAN meeting held in Toronto, ON, Canada in November 2019 and suggests the next steps required to see BCI impact the lives of children with severe neurological disease and their families.

Unified explanations seek to situate the traits of human beings in a causal framework that also explains the trait values found in nonhuman species. Disunified explanations claim that the traits of human beings are due to causal processes not at work in the rest of nature. This paper outlines a methodology for testing hypotheses of these two types. Implications are drawn concerning evolutionary psychology, adaptationism, and anti-adaptationism.

Very little has been done to find out what corporations have done to build ethical values into their organizations. In this report on a survey of 1984 Fortune 1000 industrial and service companies the Center for Business Ethics reveals some facts regarding codes of ethics, ethics committees, social audits, ethics training programs, boards of directors, and other areas where corporations might institutionalize ethics. Based on the survey, the Center for Business Ethics is convinced that corporations are beginning to take steps (...) to institutionalize ethics, while recognizing that in most cases more specific mechanisms and strategies need to be implemented to make their ethics efforts truly effective.

Much previous study has been done on the degree spectra of prime models of a complete atomic decidable theory. Here we study the analogous questions for homogeneous models. We say a countable model A has a d-basis if the types realized in A are all computable and the Turing degree d can list $\Delta _{0}^{0}$ -indices for all types realized in A. We say A has a d-decidable copy if there exists a model B ≅ A such that the elementary (...) diagram of B is d-computable. Goncharov, Millar, and Peretyat'kin independently showed there exists a homogeneous A with a 0-basis but no decidable copy. We prove that any homogeneous A with a 0'-basis has a low decidable copy. This implies Csima's analogous result for prime models. In the case where all types of the theory T are computable and A is a homogeneous model with a 0-basis, we show A has copies decidable in every nonzero degree. A degree d is 0-homogeneous bounding if any automorphically nontrivial homogeneous A with a 0-basis has a d-decidable copy. We show that the nonlow₂ $\Delta _{2}^{0}$ degrees are 0-homogeneous bounding. (shrink)

There are growing concerns that increased screen device usage may have a detrimental impact on classroom behaviour and attentional focus. The consequences of screen use on child cognitive functioning have been relatively under-studied, and results remain largely inconsistent. Screen usage may displace the time usually spent asleep. The aim of this study was to examine associations between screen use, behavioural inattention and sustained attention control, and the potential modifying role of sleep. The relations between screen use, behavioural inattention, sustained attention (...) and sleep were investigated in 162 6- to 8-year-old children, using parent-reported daily screen use, the SWAN ADHD behaviour rating scale, The sustained attention to response task and the children’s sleep habits questionnaire. Tablet use was associated with better sustained attention performance but was not associated with classroom behavioural inattention. Shorter sleep duration was associated with poorer behavioural inattention and sustained attention. Sleep quality and duration did not act as mediators between screen usage and behavioural inattention nor sustained attention control. These findings suggest that careful management of the amount of time spent on electronic screen devices could have a beneficial cognitive impact on young children. The results also highlight the critical role of sleep in enhancing both behavioural attention and sustained attention, which are essential for supporting cognitive development and learning. (shrink)

Although prior work on ethical decision-making has examined the direct impact of magnitude of consequences as well as the direct impact of emotions on ethical judgments, the current research examines the interaction of these two constructs. Building on previous research finding disgust to have a varying impact on ethical judgments depending on the specific behavior being evaluated, we investigate how disgust, as well as happiness and sadness, moderates the effect of magnitude of consequences on an individual’s judgments of another person’s (...) unethical behavior. Specifically, we propose and find that because disgust and happiness are both associated with more heuristic-based processing, they both lead to a stronger reliance on the magnitude of consequences when forming ethical judgments. In contrast, because sad and neutral emotional states are associated with more systematic processing, they both result in a weaker reliance on the magnitude of consequences. As such, the effect of magnitude of consequences on judgments of unethical behaviors is stronger when individuals making the judgments are experiencing disgust or happiness versus sadness or a neutral state. This research shows that ethical judgment severity is contingent on individual-level factors, particularly the current emotional state being experienced by the individual, interacting with magnitude of consequences to impact the ethical decision-making process.

En este ensayo se propone una lectura de la novela Sopa de caracol (2002) del escritor guatemalteco Arturo Arias, centrada en el tema de la función de la sexualidad como elemento desubjetivante del protagonista. Se examina también cómo la estética del grotesco y el modelo carnavalesco son puestos en movimiento para desestabilizar la identidad de género y así mostrar la imposibilidad de reconstruirse después de la catástrofe de la guerra.

Let K be a family of structures, closed under isomorphism, in a fixed computable language. We consider effective lists of structures from K such that every structure in K is isomorphic to exactly one structure on the list. Such a list is called a computable classification of K, up to isomorphism. Using the technique of Friedberg enumeration, we show that there is a computable classification of the family of computable algebraic fields and that with a 0'-oracle, we can obtain similar (...) classifications of the families of computable equivalence structures and of computable finite-branching trees. However, there is no computable classification of the latter, nor of the family of computable torsion-free abelian groups of rank 1, even though these families are both closely allied with computable algebraic fields.
