We discuss two desirable properties of deflationary truth theories: conservativeness and maximality. Joining them together, we obtain a notion of a maximal conservative truth theory – a theory which is conservative over its base, but can’t be enlarged any further without losing its conservative character. There are indeed such theories; we show however that none of them is axiomatizable, and moreover, that there will be in fact continuum many theories of this sort. It turns out in effect that the deflationist still needs some additional principles, which would permit him to construct his preferred theory of truth.  相似文献

The purpose of this research was to identify the number of sessions required for a new investigator to become proficient at evoking an H-reflex in the flexor carpi radialis (FCR), in comparison to an experienced investigator. 31 students from Brock University in the greater Niagara region (16 women M age = 32.2, SD = 8.9 yr.; 15 men M age = 27.8, SD = 7.8 yr.) with no known neurological disorders volunteered and completed two test sessions performed by either an experienced or a novice investigator. In randomized order, both investigators stimulated each subject's median nerve 10 times, once every 15 sec. Each session included the measurement of the subject's flexor carpi radialis maximal M-wave amplitude and H-reflex amplitude and latency with surface electromyographic electrodes. The intraclass correlation coefficients (ICC) indicated an adequate correlation between investigators for both M-wave maximal amplitude and H-reflex at 5% of the M-wave maximal amplitude (.84 and .70, respectively). However, there was a low correlation (.38) between the latency values obtained by the two investigators. The peak-to-peak amplitudes of the H-reflex and M-wave do not appear to be influenced by experience of the tester. The latency of the response, however, appears to have an associated learning curve, improving in consistency with increasing practice of tester.  相似文献

Poor Mental Health Literacy (MHL), i.e. knowledge and beliefs about bulimia nervosa (BN), among health professionals may contribute to low rates of recognition and less optimal management. The aim of this study was to investigate the BN-MHL of health professionals. A total of 534 professionals selected randomly from Internet based lists were surveyed with a MHL questionnaire regarding a fictional vignette of a woman with BN. One hundred and thirty-six dieticians, 68 psychologists and 97 counselors, total 56% (n = 301) responded. The majority of respondents indicated the woman in the vignette suffered from BN (49%) or an eating disorder (20%) and endorsed evidenced based approaches. On post hoc between group analyses there was a trend (p = .02) for dieticians and psychologists to be more likely than counselors to accurately identify the diagnosis of BN. Dieticians and psychologists were also more likely than counselors to endorse a psychologist as the most helpful treatment provider (p<.001) and to be more likely to endorse cognitive behavioral therapy as the most helpful treatment (p<.001). These results indicate a need for greater training and support for non specialist primary care health professionals.  相似文献

Recent work shows that the inability to inhibit basic motor responses (like pressing a button) is related to overeating, weight gain and overweight. In the present study it was tested whether this inability to inhibit motor responses - or impulsivity - can differentiate between successful and unsuccessful restrained eaters. A typical preload and food exposure paradigm was used and it was hypothesized that only the high-restrained eaters that are simultaneously inefficient inhibitors of prepotent motor responses would overeat when confronted with tempting foods. In line with the hypothesis, the data show that overeating follows from an interaction between restraint and impulsivity; high-restrained eaters only overate when they were also impulsive. It is concluded that being restrained per se is not a determinant of overeating. Being a restrained eater only bears the risk of overeating in case of coexisting impulsivity.  相似文献

Egoism is a personality trait that is associated with self‐enriching and self‐centred behaviours. Research has suggested that egoism lies beyond the Big Five personality factors. Recently, the HEXACO model of personality has been proposed as an alternative to the Big Five model. In three studies, the relation between the HEXACO Personality Inventory and egoism, conceptualized using three different questionnaires (DPQ Egoism, SPI Egotism and the Egoism Scale), is investigated. In all three studies, the HEXACO Honesty–Humility factor scale was the most important predictor of egoism. Additionally, in two studies in which FFM measures were used, the HEXACO Personality Inventory explained more variance in egoism than did the FFPI (Study 2) and the NEO‐PI‐R (Study 3).

多动症的遗传学研究概述   总被引:2,自引:0,他引:2  
多动症多始于儿童期,并能持续至成年期。传统的家庭、双生子和养子女研究表明,多动症是受遗传影响的。双生子研究现在被用来定义多动症表型,分析性别差异,测试基因对持续性和共病的影响,以及研究遗传与环境的互动。多动症的分子遗传学研究集中在功能候选基因的关联分析上。多动症与DRD4和DRD5的关系比较一致。最新的研究也显示COMT的影响。关联分析(linkage analysis)显示这些单个基因的影响都不大。这个领域还有待于大规模的“全基因关联”分析。至今为止的证据显示,研究基因-表型关联以及基因与环境互动对多动症的影响将日趋重要  相似文献

The aim of this article is to identify the theological potential for interreligious relations as embodied in the everyday life of ordinary Christians in South India. The empirical study that underlies the discussion is based on interviews with lay churchgoers and pastors from Pentecostal and mainline Protestant churches in Bangalore. The beliefs they articulate, as well as the practices they carry out in their daily lives, are defined as their lived theology. This is analyzed through the terminological framework of theology in four voices. Interviewees express beliefs that emphasize the superiority of Christianity over other religions and the importance of evangelism. Nevertheless, in everyday life they prioritize respect for religious others and maintenance of relationships with them over sharing an exclusivist message about Christ. Their lived theology emphasizes relatedness across religious boundaries and the priority of showing love for the neighbour in practice.  相似文献

Matrix training is a teaching strategy designed to facilitate generative responding through a process termed recombinative generalization. A skill that has yet to be addressed with matrix training is tacting time increments. Given the two‐component features of time telling (i.e., hours and minutes) and the numerous teaching targets, matrix training was implemented for such behavior with two adults with developmental disabilities. This study used a 12 × 12 matrix that consisted of 144 time increments. Participants were taught 12 time increments, and probes were conducted to assess the remaining 132 untrained time increments. The participants responded correctly to approximately 50% of the untrained time increments during the post‐assessment phase. Limitations and future research are discussed.  相似文献

The present study investigated the effect of threat of physical harm on the aggressive behavior of intoxicated and nonintoxicated subjects. Forty male undergraduates competed in a reaction time task in which they could deliver shock to an increasingly provocative opponent. In the threat condition, subjects could be hurt by the opponent (they wore a shock electrode), while in the no-threat condition, they could not be hurt by the opponent (the electrode was removed prior to the competition). The results indicated that under conditions of low provocation, the intoxicated subjects behaved more aggressively than the nonintoxicated subjects in both the threatening and nonthreatening condition. However, under conditions of increasing provocation, only the intoxicated subjects in the threatening condition increased their shock settings.  相似文献
