Cet article revisite la théorie althussérienne de l’idéologie en se focalisant sur la place centrale – mais qui passe souvent inaperçue – que la question du corps y occupe. Il avance l’idée que l’idéologie, au sens où Althusser l’entend, doit son existence et sa réalité au corps humain. Pour ce faire, il va démontrer que chez Althusser : (1) la notion de l’« idéologie en général » présuppose celle du « corps en général » ; (2) la question du double (...) rapport de l’idéologie à la science d’un côté et à la société de l’autre témoigne de l’importance de celle du corps ; (3) c’est parce que l’homme a/est un corps qu’il est un animal idéologique, c’est-à-dire qu’il vit dans et par l’idéologie, et qu’en ce sens l’idéologie est comparable à l’atmosphère, sans laquelle il n’y a pas de respiration, et donc pas de vie possible.

We say that a computably enumerable (c. e.) degree a is plus-cupping, if for every c.e. degree x with $0 < x \leq a$ , there is a c. e. degree $y \not= 0'$ such that $x \vee y = 0/\'$ . We say that a is n-plus-cupping. if for every c. e. degree x, if $0 < x \leq a$ , then there is a $low_n$ c. e. degree 1 such that $x \vee l = 0'$ . Let PC (...) and $PC_n$ be the set of all plus-cupping, and n-plus-cupping c. e. degrees respectively. Then $PC_{1} \subseteq PC_{2} \subseteq PC_3 = PC$ . In this paper we show that $PC_{1} \subset PC_2$ , so giving a nontrivial hierarchy for the plus cupping degrees. The theorem also extends the result of Li, Wu and Zhang [14] showing that $LC_{1} \subset LC_2$ , as well as extending the Harrington plus-cupping theorem [8]. (shrink)

This compilation brings together 20 essays of Santiago Ramón y Cajal (1852-1934), the neuroscientist par excellence and 1906 Nobel Laureate in Medicine, on topics beyond neuroanatomy, most appearing in English for the first time. The annotated collection makes available in one handy volume Cajal's ideas on psychology, art and education, still current and still relevant, derived from his books La Psicología de los Artistas, Charlas de Café, El Mundo Visto a los Ochenta Años, Pensamientos Pedagógicos and Escritos Inéditos. An acute (...) observer of the intellectual and social scene of the avant-garde, Cajal emerged in 20th-century Spain in a further role as a philosopher and educator. The contents bespeak Cajal's inquiry into the varieties of human experience and shed new light on the breadth of his genius, imagination and passion, helping us to rethink what we thought we already understood about Don Santiago's own mind.

Sudoku puzzles, which are popular worldwide, require individuals to infer the missing digits in a 9 9 array according to the general rule that every digit from 1 to 9 must occur once in each row, in each column, and in each of the 3-by-3 boxes in the array. We present a theory of how individuals solve these puzzles. It postulates that they rely solely on pure deductions, and that they spontaneously acquire various deductive tactics, which differ in their difficulty (...) depending on their “relational complexity”, i.e., the number of constraints on which they depend. A major strategic shift is necessary to acquire tactics for more difficult puzzles: solvers have to keep track of possible digits in a cell. We report three experiments corroborating this theory. We also discuss their implications for theories of reasoning that downplay the role of deduction in everyday reasoning. (shrink)

The medical ethics of a physician’s relationship with a prisoner who is participating in a collective hunger strike has become a major public, professional, and governmental concern in The Republic of Turkey. This article examines the Turkish experience and debate about physician ethics during prison hunger strikes. It is hoped that this analysis will be of use to those formulating policy in similar situations.

This study investigates the impact of labor unionization on stock price crash risk. We find that labor unionization is negatively associated with stock price crash risk. Such negative relation is more pronounced when firms can intimate more credible evidence on unfavorable prospects and when firms face more powerful labor unions. Our findings are consistent with the notion that firms take strategic actions to reduce the bargaining advantages enjoyed by labor unions and that labor unions force firms to take less risky (...) investments and discontinue underperformed projects more timely, which leads to lower stock price crash risk.

En 1868, impulsado por el krausismo, se introdujo en el Bachillerato español una nueva asignatura, la Antropología. Nicolás Salmerón que no fue ajeno a la novedad, comenzó a escribir un texto para ella sobre la base de las explicaciones de clase que él mismo impartía en su Colegio Internacional. Ese texto dio lugar al libro que nos ocupa que, aunque inédito e incompleto, permite ofrecer una visión filosófica más completa de su etapa juvenil. Su mérito estriba en haber articulado en (...) disciplina una de las materias clave de la filosofía krausista y ofrecer una idea global e integradora de lo que con el tiempo se llamaría Antropología filosófica.

It is time for the noon conference. Your job is to impart a career-changing experience in ethics to a group of students and interns gathered from four different schools with varying curriculums in ethics. They have just finished 1½ h of didactic sessions and lunch. One third of them were on call last night. Your first job is to keep them awake. The authors argue that this “tragic case” approach to ethics education is of limited value because it limits understanding (...) of moral problems to dilemmas; negates the moral agency of the student; encourages solutions that are merely intellectual; and suggests that ethical encounters are a matter for experts. The authors propose an alternative that focuses on three issues: the provider-patient relationship, the relationships between providers in the everyday world of health work and, the social position of healthcare providers in society. In this approach, teachers are not experts but more like guides on a journey who help students to learn that much of ethical practice comprises living through difficult situations of caring for vulnerable others and who help students to navigate some of these difficulties.

Although performance pressure has desirable consequences, there is evidence that it can produce unintended outcomes as employees tend to engage in dysfunctional and unethical behaviors to meet performance goals. Thus, the process through which employees think and behave unethically under performance pressure deserves more research attention. This study goes beyond the stress-appraisal perspective and investigates whether and when performance pressure influences individual work mindsets and behaviors from a moral reasoning perspective. Specifically, we contend that performance pressure is related to employee (...) expediency through moral decoupling. We further hypothesize dialectical thinking and moral identity to be the boundary conditions of the proposed relationships. Analyses of data from a field study in three waves provide support for most of the hypotheses. In particular, we find that moral decoupling accounts for additional variance after we control for the stress-appraisal effect of performance pressure on employee expediency. The study offers several contributions to the literature on performance pressure and unethical behavior. (shrink)

A highly idiosyncratic search for universal laws governing the development of a feeling of well-being and creative involvement in life. Numerous, somewhat mystical, experiences are described with enthusiasm and candor, but, perhaps, uncertain significance for those less inclined toward mysticism.—N. Y.

Henrich et al. address how culture leads to cognitive variability and recommend that researchers be critical about the samples they investigate. However, there are other sources of variability, such as individual strategies in reasoning and the content and context on which processes operate. Because strategy and content drive variability, those factors are of primary interest, while culture is merely incidental.

We give several characterizations of Schnorr trivial sets, including a new lowness notion for Schnorr triviality based on truth-table reducibility. These characterizations allow us to see not only that some natural classes of sets, including maximal sets, are composed entirely of Schnorr trivials, but also that the Schnorr trivial sets form an ideal in the truth-table degrees but not the weak truth-table degrees. This answers a question of Downey, Griffiths and LaForte.

We study the connection between Schnorr triviality and genericity. We show that while no 2-generic is Turing equivalent to a Schnorr trivial and no 1-generic is tt-equivalent to a Schnorr trivial, there is a 1-generic that is Turing equivalent to a Schnorr trivial. However, every such 1-generic must be high. As a corollary, we prove that not all K-trivials are Schnorr trivial. We also use these techniques to extend a previous result and show that the bases of cones of Schnorr (...) trivial Turing degrees are precisely those whose jumps are at least 0". (shrink)
