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

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

Positional bias is a pattern of responding to a specific location that can be influenced by response effort and/or prior learning history. Prior research on positional bias within stimulus preference assessments have focused primarily on its use in paired stimulus assessments due to the complex nature of the multiple stimulus without replacement (MSWO) preference assessment. The present study is a secondary data analysis that utilized four different methods to measure side and center bias in a MSWO preference assessment for 19 young children with autism spectrum disorder. Participants displayed varying degrees of biased responding but collectively engaged in minimal biased responding. This study includes an analysis of the four methodologies, discussion of general patterns of responding, and general recommendations for the application of these methodologies in future research. 相似文献

This paper discusses specific behavioral research needs by law enforcement and justice systems to guide forensic decision-making in areas of targeted violence. Continuing incidents of stalking, workplace violence, and threats to public figures underscore the importance of developing empirically based risk assessment and intervention strategies. Reviewing briefly the relevant literatures in these areas, this paper describes deficits in these literatures and the absence of a model for integrating research and practice in applied settings. The U.S. Secret Service Behavioral Research Program is explored as one example of how behavioral science expertise may be integrated with law enforcement responsibilities. Considerations associated with building behavioral research capacities in applied settings are examined in the context of differences in professional orientation, values, and access to information. Specific research directions to improve understanding of targeted violence are recommended along with suggestions for ways in which the psychology-law field may facilitate integration of research into practice. © 1998 John Wiley & Sons, Ltd. 相似文献

The validity and reliability of the Spanish version of the 2 scales measuring work-related well-being proposed by P. Warr (1990; Anxiety-Contentment and Depression-Enthusiasm) were examined in a cross-sectional questionnaire study among 299 Spanish factory employees. Two methods suggested by Warr (1990) to control the response bias (acquiescent response set) were used. The 1st method involved separate analyses for the 6 positive and 6 negative items that make up the 2 scales. The 2nd was a series of 4 principal component analyses with oblique rotation on the estimated response set controlled in partial correlation between each item. The results support the existence of these 2 independent scales for measuring work-related psychological well-being as hypothesised by Warr (1990). However, 2 main problems appear: the cross-loading of the items contented and cheerful and the fact that only I factor appears in the pre-rotated solution. Possible explanations for these results are discussed. 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 qualitative study explores adolescents’ perceptions of help-seeking behaviors in the context of a hypothetical suicide
crisis. Cauce and colleague’s (2002, Journal of Consulting and Clinical Psychology, 70, 44–55) model was used to examine help-seeking behaviors in 3 domains: problem recognition, decision to seek help, and selection
of helpers. Forty-two church-going African American adolescents participated in 1 of 6 focus groups that discussed ways to
help a hypothetically suicidal student in a vignette. Findings suggest that although the majority of youth had been exposed
to a suicidal peer (76%), they were unsure of the seriousness of suicide as a problem in the African American community. The
findings suggest that youth were less comfortable with formal interventions in school, religious institutions or traditional
mental health settings. However, youth were open to community-based programs that could be located in school, church or community
settings if helpers were: young adults, empathic listeners, non-judgmental, maintained confidentiality, and viewed as “natural
helpers”. Implications for developing church-based suicide interventions are discussed.

Burgeoning evidence points to a positive association between cigarette smoking and depression. Moreover, depressive symptomatology, whether historical, current, or subsyndromal, appears to negatively influence smoking cessation efforts. Whereas depression is typically assessed via clinical interview or self-report, rarely are the known neurocognitive deficits linked to depression (e.g., global slowing) assessed in the context of smoking cessation research. Hence, this study examined whether simple reaction time -- color naming of affectively neutral words -- is predictive of 12-month smoking cessation outcome among a sample of formerly depressed smokers (N = 28). Results revealed a significant, positive correlation between reaction time and depressive symptoms such that those who exhibited slower reaction times were at heightened risk to relapse. Baseline depressive symptoms, as assessed via self-report, neither correlated with nor predicted smoking cessation outcome. Results from logistic regression analyses further showed that reaction time added incremental variance to the prediction of smoking cessation outcome. Therefore, simple reaction time may capture aspects of depression not typically assessed in self-report questionnaires. These results are discussed in terms of their theoretical and clinical implications for smoking cessation research. 相似文献
