This paper explores the similarities between the conceptual structure of quantum theory and relational biology as developed
within the Rashevsky-Rosen-Louie school of theoretical biology. With this aim, generalized quantum theory and the abstract
formalism of (M,R)-systems are briefly presented. In particular, the notion of organizational invariance and relational identity
are formalized mathematically and a particular example is given. Several quantum-like attributes of Rosen’s complex systems
such as complementarity and nonseparability are discussed. Taken together, this work emphasizes the possible role of self-referentiality
and impredicativity in quantum theory. 相似文献

In this contribution, we analyse how nanoscience and nanotechnology have given birth to an important environmental health controversy regarding the potential sanitary dangers of engineered nanomaterials. We show how this controversy is part of a larger picture, made of a series of social and scientific disputes about the effects of man made chemicals on the human body. We show how these disputes have contributed throughout the 20th century to the emergence and the transformation of toxicology as a scientific field, and to test the robustness of the dose paradigm that constitues the cornerstone of this discipline. We suggest that the contemporary emergence of a new scientific field known as "nanotoxicolgy" must be interpreted as a successful adaptation of this paradigm to the specific toxicological questions raised by engineered nanomaterials. 相似文献

A feeling of belonging to an academic context is a critical determinant of academic achievement and persistence, particularly for students of color. Despite the fact that students of color are generally more susceptible to fluctuations in belonging uncertainty than White students, survey design can unintentionally mask this reality. We investigated whether context effects undermine the accurate assessment of belonging uncertainty in junior high and high school students (Study 1) and college students (Study 2). Considering one's ethnic identification (Study 1) and personal experiences with discrimination (Study 2) threatens sense of belonging in students of color, but not White students. Researchers should consider question order within surveys so as not to artificially mask belonging uncertainty in students of color. 相似文献

Alexithymia has been described as an important dimension in several medical and psychiatric diseases. Chronic urticaria (CU) is a chronic condition, in which treatment is difficult. Our aim is to determine the prevalence of alexithymia traits in patients with CU, and to identify the relationships between alexithymia and psychological variables and quality-of-life dimensions. Fifty-five sequential CU patients in a faculty ambulatory specialized consultation, with an average age of 44.92, were compared with 31 healthy volunteers. Both groups were studied by means of validated scales for alexithymia (Toronto Alexithymia Scale [TAS-20]), attachment (Adult Attachment Scale-R [AAS-R]), psychopathology (Brief Symptom Inventory [BSI]), personality dimensions (The NEO Five-Factor inventory [NEO-FFI]) and quality of life (Short Form-36 [SF-36]). The classification of CU reactions was obtained from the patient's history, physical examination, laboratory assessment and histopathologic findings. All the patients were under treatment with sedating H1-antihistamines, non-sedating H1-antihistamines combination of H1 and H2 blocker, 2 H1-antihistamines and 3 H1-antihistamines. High traits of alexithymia were found on CU patients (56.9%) as well as high symptom rates of anxiety. Alexithymia traits were significantly positively correlated with insecure attachment styles, with psychopathological symptoms, and with the defense mechanism turn against self. We also reported a significant negative correlation between alexithymia traits and the dimensions of quality of life. Insecure attachment styles were positively correlated with psychopathological symptoms and negatively correlated with quality of life. We did not find significant statistical correlations between alexithymia and clinical variables. CU patients present serious difficulty in dealing with emotion arousal. There is strong evidence of a psychosomatic specificity in CU, with marked alexithymic traits. 相似文献

Negative emotions increase self-focused attention, a core feature of depression and anxiety-related disorders. However, the cognitive mechanisms associated with the tendency to self-focus-and, conversely, with the ability to voluntarily disengage attentional resources from the self and direct them towards the external environment-remain poorly understood. Thus, this study aimed to examine whether a specific cognitive control mechanism that directs attention between self-generated thoughts and external information might moderate the relationship between dysphoria and maladaptive self-referential thinking. Results showed that dysphoria increases the frequency of rumination, self-blame, and catastrophising, especially for participants who have more difficulty in switching from self-generated thoughts to information provided by the environment. These results shed new light on the cognitive mechanisms underlying maladaptive self-referential thinking associated with dysphoria. More specifically, this specific cognitive mechanism might play a key role in the maintenance or amplification of a depressed mood. 相似文献

This article follows the culmination of the scientific thought of the neurobiologist Christfried Jakob (1866-1956) during the later part of his career, based on publications from 1930 to 1949, when he was between 64 and 83 years of age. Jakob emphasized the necessity of bridging philosophy to the biological sciences, neurobiology in particular. Thus, we consider him as one of the early protagonists in the emergence of neurophilosophy in the 20th century. The topics that occupied his mind were the foundations for a future philosophy of the brain, and the 'neurobiogenetic', 'neurodynamic', and 'neuropsychogenetic' problems in relation to how consciousness emerges. Jakob's views have many elements in common with great thinkers of philosophy and psychology, including Immanuel Kant, William James, Edmund Husserl, Henri Bergson, Jean Piaget and Willard Quine. A common denominator can also be discerned between Jakob's dynamic approach and certain aspects of cybernetics and neurophenomenology. Jakob propounded the interdisciplinarity of sciences as an indispensable tool for ultimately solving the enigma of consciousness. 相似文献

Two ways to improve worked examples are investigated: presenting them in a segmented format (i.e., in pieces separated by blank lines) and instructing students to segment them actively (i.e., students must divide the examples in pieces). Segmented examples are expected to support learning because they show which information elements belong together. Learners might also be encouraged to think about which information elements belong together when they are instructed to actively segment, but on the negative side, this is an additional task that might impose extra cognitive load without facilitating learning. Results showed that students in the actively segmenting condition invested more effort in learning than students in the other conditions without performing better. Furthermore, studying segmented examples required less effort to achieve equal learning outcomes than studying nonsegmented ones. So, presenting learners with segmented examples improved the efficiency of the learning process, whereas instructing them to actively segment decreased this efficiency.

Rapha?l Micheli 《Argumentation》2012,26(1):115-126
If we consider the field of argumentation studies, we notice that many approaches consider argumentation in a pragmatic manner and define it as a verbal activity oriented towards the realization of a goal. The idea that subtends—in an explicit or implicit way—most of these approaches is that argumentation fundamentally aims
to produce an effect upon an addressee, and that this effect consists in a change of attitude with respect to a viewpoint: argumentation theories inevitably confront the issue of persuasion. In this article, I defend, on the contrary, the hypothesis
that it is not necessary to have recourse to the notion of persuasion, nor even to speak of an attempt to provoke a change of attitude in the addressee, in order to develop a general definition of argumentation. It seems to me that there are serious reasons to uncouple, insofar
as a definition is concerned, argumentation and persuasion. I will look to identify these reasons, to formulate them and to
evaluate their strength. In the same vein as recent works by Christian Plantin and Marc Angenot, I will try to contribute
to the development of a non-persuasive conception of argumentation. Such a conception bases the definition of argumentation on the pragmatic aims of “justification”
and “positioning”, as well as on the articulation of a discourse and a counter-discourse. I argue that such a conception might
offer a better empirical adequacy than those that link, insofar as a definition, the argumentative activity and the persuasive
aim. 相似文献

The application of neuroscience to marketing, and in particular to the consumer psychology of brands, has gained popularity over the past decade in the academic and the corporate world. In this paper, we provide an overview of the current and previous research in this area and explain why researchers and practitioners alike are excited about applying neuroscience to the consumer psychology of brands. We identify critical issues of past research and discuss how to address these issues in future research. We conclude with our vision of the future potential of research at the intersection of neuroscience and consumer psychology. 相似文献
