The techno-scientific development has no frontier, but the legal systems still take roots in local and cultural references. French Law is built on a continental model and conveys values and preferences of the French population, including an essential role given to the State and to textual requirements. Until now, French law has been modified to cope with new and emerging technologies issues with the idea that they can be taken one after the other, on the fringes of the classic legal problems. Do the announcement of a convergence between Nanotechnologies, Biotechnologies, the sciences of Information and Cognition (NBIC) change the situation? According to “converging technologies” partisans, a lot of other deep perturbations may occur. Therefore, it could be pertinent to assess the legal implications of NBIC convergence. But trying to do so, a French legal scholar may first feel (and express) perplexity. What is the “convergence NBIC”? To answer, do we have to wonder which reality hides behind the expression or is it necessary to admit that the speeches are here more important to analyze than a hypothetical realization? Does it imply new legal questions? Do we need new methods to enlighten what is at stake? Is it a new challenge, stimulating the imagination of lawyers and legal scholars, or, on the contrary, is it a new illustration of the Economy of the promises, revealing big risks of vain (or inappropriate) intellectual and normative production? This article is dedicated to enlighten the important difficulties which mark out the road towards the answers to the legal questions raised by the “NBIC convergence”.  相似文献

The paper presents a dilemma for both epistemic and non‐epistemic versions of conceivability‐based accounts of modal knowledge. On the one horn, non‐epistemic accounts do not elucidate the essentialist knowledge they would be committed to. On the other, epistemic accounts do not elucidate everyday life de re modal knowledge. In neither case, therefore, do conceivability accounts elucidate de re modal knowledge.  相似文献

The objectives of the study were to analyze the psychometric properties, factor structure and internal consistency of the Spanish version of the Thought-Shape Fusion Questionnaire (TSF-Q), as well as to determine its validity by evaluating the relationship of the TSF-Q to different instruments. Two groups were studied: one comprising 146 patients with a diagnosis of anorexia (n = 82), bulimia (n = 33) or unspecified eating disorder (n = 31), and another group of 115 undergraduates with no history of psychological disorder. All participants completed the TSF-Q, TAF-Q, EDI-2, STAI, BDI and SCL-90-R. Differences in TSF-Q scores between the diagnostic subgroups were also analyzed. Two factors were obtained which coincided with the two sections indicated by the authors of the questionnaire: conceptual and interpretative. The internal consistency of the TSF-Q and its subscales was determined by means of Cronbach's alpha, with values ranging between .93 and .96. The correlations with other instruments reflected adequate validity. There were no significant differences between the diagnostic subgroups. The Spanish version of the TSF-Q meets the psychometric requirements for measuring thought-shape fusion and shows adequate internal consistency and validity.  相似文献

Transracial adoptees represent a specific group of immigrants who experience unique immigration processes that bring them face‐to‐face with two cultural backgrounds: that of their heritage culture on one hand and that of their national culture on the other hand. However, there is a scarcity of studies focused on the way these processes unfold within adoptive families. This study was aimed at exploring how transracial adoptees cope with the construction of their ethnic identity. Administering a self‐report questionnaire to 127 transracial adoptees and their mothers, for a total of 254 participants, we first investigated the association between mothers' cultural socialisation (enculturation and preparation for bias strategies) and adoptees' ethnic identity (i.e. ethnic identity exploration and ethnic identity affirmation dimensions). We then investigated whether ethnic identity affects self‐esteem by testing the hypothesis that national identity moderates the relationship between ethnic identity and self‐esteem. Results revealed that mothers' enculturation (but not their preparation for bias) supported adoptees' ethnic identity exploration, which in turn was positively associated with ethnic identity affirmation. Moreover, we confirmed the moderation effect: ethnic identity affirmation enhanced the level of self‐esteem, but only for those adoptees who perceived a higher degree of national identity affirmation.  相似文献

Separate groups of women estimated the painfulness of labor contractions either immediately (perceptual judgments) or at time intervals varying from 8 to 48 h after their completion (memorial judgments). The pain judgments of individual uterine contractions were related functionally to the biometrically measured magnitude of these contractions. Perceived and remembered painful sensations were related to referent intensities by power functions governed, as a rule, by exponents greater than unity. Exponents for the memory functions were consistently greater than those for the perceptual functions. Psychophysics done in the field can help decide theoretical issues in addition to providing useful practical information.  相似文献

A method is described for simulating the variability of outcomes encountered in a variety of settings. Outcome values falling within a specified range are randomly generated and presented across subjects and trials, so that, over time, the average values seen by all subjects in a condition are the same. Randomly varying reinforcement dimensions (such as magnitude) over trials for each subject is recommended to enhance both the internal and the external validity of laboratory results. In addition, it can be used to study the effects of the variability or uncertainty of outcome dimensions such as magnitude and duration in investigations of behaviors such as matching, melioration, and behavioral momentum.  相似文献

Copies of notes taken during a lecture were obtained from first-year psychology students, and the relations examined between measures derived from these (the number of points recorded, the number of words written, and the number of words per point) and a number of variables measuring personality and approach to studying. Three variables were found to be related to the measures derived from the notes: older students, those scoring high on strategic learning (strategy component) and those scoring high on surface learning (motivational component), both measured by questions derived from Biggs (1979), produced longer notes and recorded more of the important points in the lecture. The results suggest that relations between approaches to studying and specific study behaviour are not straightforward and require more detailed investigation.  相似文献

The notion of monadic three-valued ukasiewicz algebras was introduced by L. Monteiro ([12], [14]) as a generalization of monadic Boolean algebras. A. Monteiro ([9], [10]) and later L. Monteiro and L. Gonzalez Coppola [17] obtained a method for the construction of a three-valued ukasiewicz algebra from a monadic Boolea algebra. In this note we give the construction of a monadic three-valued ukasiewicz algebra from a Boolean algebra B where we have defined two quantification operations and * such that *x=*x (where *x=-*-x). In this case we shall say that and * commutes. If B is finite and is an existential quantifier over B, we shall show how to obtain all the existential quantifiers * which commute with .Taking into account R. Mayet [3] we also construct a monadic three-valued ukasiewicz algebra from a monadic Boolean algebra B and a monadic ideal I of B. The most essential results of the present paper will be submitted to the XXXIX Annual Meeting of the Unión Matemática Argentina (October 1989, Rosario, Argentina).  相似文献
