S. Jakowski introduced the discussive prepositional calculus D
2as a basis for a logic which could be used as underlying logic of inconsistent but nontrivial theories (see, for example, N. C. A. da Costa and L. Dubikajtis, On Jakowski's discussive logic, in Non-Classical Logic, Model Theory and Computability, A. I. Arruda, N. C. A da Costa and R. Chuaqui edts., North-Holland, Amsterdam, 1977, 37–56). D
2has afterwards been extended to a first-order predicate calculus and to a higher-order logic (cf. the quoted paper). In this paper we present a natural version of D
2, in the sense of Jakowski and Gentzen; as a consequence, we suggest a new formulation of the discussive predicate calculus (with equality). A semantics for the new calculus is also presented. 相似文献

It is shown that the notions of aggressive behavior as ‘intentional emission of noxious stimulation’ (Buss, 1961, 1963, 1966, 1971) and that of ‘injuriating goal response’ (Dollard, Doob, Miller, Mower and Sears, 1939) are identical. The usefulness of these theories to predict S's reaction to the reception of a given noxious stimulation is questioned. It is suggested that S's reactions to noxious stimulation may or may not be aggressive, depending on whether the noxious stimulation S receives is interpreted as being a behavior justified by the nom in the situation, or as reflecting an aggressive intent of O. It is hypothesized that the norms established in the situation depend on (i) victim's perception of the noxious stimulation received as being instrumental for O's goal attainment, (ii) victim's perception of the value of O's goal, and (iii) the value of victim's own goal. The establishment of norms regulating the exchange of noxious stimulation between Ss is operationalized in two experiments. Aggression, defined as an infringement of these norms, is measured. In Experiment I, participate 56 female students, and in Experiment 2, 80 male students. Subject is alternately victim (he performs a sensorimotor task and receives an electric shock) and aggressor (he shocks the other S). In Experiment I it is found that Ss counteraggress faster and more frequently if they interpret the shock received from the partner as an infringement of the norm. In Experiment 2, Ss do not counteraggress more frequently, but they do counteraggress faster and evaluate O more negatively. It is concluded that the results clearly contradict current positions and favor the authors' cognitive reformulation of the determinants of aggressive behavior. 相似文献

We compared personality profiles of men with sexual dysfunction (n = 51) to those of age-matched men with a primary diagnosis of paraphilia (n = 51) employing the NEO Personality Inventory (NEO-PI), a measure of the five-factor model. Preliminary analyses in a large sample of patients in a sexual behaviors consultation unit supported the reliability and factorial validity of the NEO-PI for this population. Analysis of variance showed significant differences between the dysfunctional and the paraphilic groups on two of the five NEO-PI domains, Neuroticism (N) and Agreeableness (A). The group personality profile of the sexually dysfunctional men was comparable to the normative sample of the NEO-PI, except for a slight elevation in N. By contrast, men with paraphilia had a personality profile marked by high N, low A, and low Conscientiousness (C). Treatment implications of the average personality profile of the sexual dysfunction group and the distinctive personality profile of paraphilic men are discussed. 相似文献

In the past decade, clinical psychologists have developed a renewed appreciation of the value of assessment. At the same time, personality psychologists have come to agree on a fundamental taxonomy of personality traits, the five-factor model. Articles in this special series describe the model and its measurement and discuss applications in three different settings: general clinical practice, a sexual behaviors consultation unit, and a behavioral medicine clinic. This introduction raises questions about the use of personality profiles in psychodiagnosis, the range of applicability of the five-factor model, the utility of personality feedback in psychotherapy, the stability of personality scores among psychotherapy patients, and the feasibility of using personality scores to select optimal forms of treatment. This special series is intended to stimulate research on such topics. 相似文献

My aim is to discuss the history of the reception of George Herbert Mead's ideas in sociology. After discussing the methodological debate between presentism and historicism, I address the interpretations of those responsible for Mead's inclusion in the sociological canon: Herbert Blumer, Jürgen Habermas, and Hans Joas. In the concluding section, I assess these reconstructions of Mead's thought and suggest an alternative more consistent with my initial methodological remarks. In particular, I advocate a reconstruction of Mead's ideas that apprehends simultaneously its evolution over time and its thematic breadth. Such a historically minded reconstruction can be not only a useful corrective to possible anachronisms incurred by contemporary social theorists, but also a fruitful resource for their theory-building endeavors. Only then can meaningful and enriching dialogue with Mead begin. 相似文献

There is widespread evidence in favour of nitric oxide (NO) acting as a gaseous neurotransmitter in the central nervous system, diffusing from its cells of origin and affecting surrounding neuronal tissue in evanescent three-dimensional waves. This is also true of the hypothalamus, where amongst other activities NO inhibits stimulation of corticotrophin-releasing hormone (CRH) and vasopressin release by inflammatory stressors, effects thought to be mediated by binding with soluble guanylate cyclase (sGC). Carbon monoxide is being increasingly recognised as another gaseous neuromodulator, but with principal effects on other hemoproteins such as cyclo-oxygenase, and a distinctly different profile of localisation.NO is predominantly a pro-inflammatory agent in the periphery while CO is often anti-inflammatory. In the hypothalamus, the actions of CO are also distinct from those of NO,with marked antagonistic effects on the inflammatory release of vasopressin, both in vitro and in vivo, but with little involvement in the regulation of CRH. Thus, it would appear that these apparently similar gases exert quite distinct and separate effects, although they cause broadly similar overall changes in the secretion of neuroendocrine stress hormones. We conclude that these two gases may play significant but different roles in the control of the neuroendocrine stress response, but one common feature may be attenuation of inflammation-induced release of stress hormones. 相似文献

In order to develop an account of scientific rationality, two problems need to be addressed: (i) how to make sense of episodes
of theory change in science where the lack of a cumulative development is found, and (ii) how to accommodate cases of scientific
change where lack of consistency is involved. In this paper, we sketch a model of scientific rationality that accommodates
both problems. We first provide a framework within which it is possible to make sense of scientific revolutions, but which
still preserves some (partial) relations between old and new theories. The existence of these relations help to explain why
the break between different theories is never too radical as to make it impossible for one to interpret the process in perfectly
rational terms. We then defend the view that if scientific theories are taken to be quasi-true, and if the underlying logic
is paraconsistent, it’s perfectly rational for scientists and mathematicians to entertain inconsistent theories without triviality.
As a result, as opposed to what is demanded by traditional approaches to rationality, it’s not irrational to entertain inconsistent
theories. Finally, we conclude the paper by arguing that the view advanced here provides a new way of thinking about the foundations
of science. In particular, it extends in important respects both coherentist and foundationalist approaches to knowledge,
without the troubles that plague traditional views of scientific rationality. 相似文献

This study analyses the data obtained from a sample of 220 healthy full-term neonates evaluated with the Neonatal Behavioral Assessment Scale, NBAS, 3rd edition. Standard scores were obtained for each of the 35 behavioral items and analysis of the main components of all the clusters was performed. Similarly to the original scale, the five following factors were obtained: Autonomic and Motor Systems, Habituation, State Organization, State Regulation, and Social Interactive. The analysis of the reliability of these groupings reveals that it is between moderate and high (the average Cronbach's alpha coefficient was .78). 相似文献
