Kitcher's unification theory of explanation seems to suggest that only the most reductive accounts can legitimately be termed explanatory. This is not what we find in actual scientific practice. In this paper, I attempt to reconcile these ideas. I claim that Kitcher's theory picks out ideal explanations, but that our term explanation is used to cover other accounts that have a certain relationship with the ideal accounts. At times, versions and portions of ideal explanations can also be considered explanatory. 相似文献

The construction and properties of the Belief in Good Luck (BIGL) Scale are described. Three studies provide evidence that reliable individual differences exist with respect to beliefs about luck. Some individuals maintain an irrational view of luck as a somewhat stable force that tends to influence events in their own favor, while others seem to hold the more rational belief that luck is random and unreliable. Further, these beliefs showed a considerable amount of stability over time. The BIGL was significantly related to locus of control (primarily to a chance subscale), but other evidence suggested these constructs were distinct. Belief in good luck was not related to general optimism, academic pessimism, self-esteem, desire for control, or achievement motivation. There was also evidence that belief in good luck was distinct from feeling fortunate or generally satisfied with one's life. Ethnic group differences were observed for the BIGL scale, showing that Asian-Americans were more likely to endorse superstitious beliefs about luck than non-Asians. Finally, the BIGL scale was shown to predict positive expectations for the outcome of everyday situations that are typically associated with luck. This is generally in agreement with previous findings suggesting that people who believe in personal good luck react to lucky events by becoming more positive about the likelihood of future success (Darke & Freedman, 1997). In general, it is suggested that irrational beliefs about luck can serve as a source of positive expectations for the outcome of future events. 相似文献

In 1949, the neurologist Juhn Wada reported the first use of a new procedure for determining the localization of speech and language in neurological patients: examination of the effects on speech and language after injecting a barbiturate, sodium amytal, into the internal carotid artery of each hemisphere in succession. By the 1960s, Wada'sIntracarotid Amobarbital Procedure,orIAP,had become the method of choice for identifying the speech-dominant side in one kind of neurological patient, persons with epilepsy who are candidates for surgical resection, and it remains so today. In 1941, however, an American neurosurgeon, W. James Gardner, reported his use of a different anesthetization procedure for speech localization in neurological patients. Instead of injecting sodium amytal through the blood supply, as in the IAP, Gardner injected procaine hydrochloride directly into cortical tissue. In this paper, we provide a brief biography of Gardner. We then discuss his method of cortical anesthetization, the theoretical and empirical background guiding his use of this method and his choice of patients, and, finally, the fate of Gardner's method within the scientific community. 相似文献

This study describes the results of a retrospective review of patients' charts who had an advanced directive (AD) and who were hospitalized in a tertiary, acute care teaching hospital. The purpose of the review was to understand from clinical, sociological, ethical and legal perspectives the nature and utility of ADs. Findings and implications of the review are discussed in terms of: patient demographics; diagnoses; quality of ADs; influence of ADs on clinical decisions; and legal aspects of ADs. 相似文献

Using a 2×2 experimental design and data from 86 business students, the present study examined the main and interactive effects of the purpose of the request (personnel selection vs. career tracking), and applicant gender (male vs. female) on the perceived fairness of biodata. Results revealed a significant main effect for purpose and a purpose x gender interaction. Implications for the collection of biodata in the personnel selection process are discussed. 相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation. 相似文献

This study compared social values and relationships with parents among American college women of Chinese and European descent. Chinese-American women scored higher on a measure of practicality and pragmatism (mastery), hierarchy, and traditionality. The Euro-American women showed a greater interest in voluntary prosocial behaviour and philanthropy. Both groups of women reported having a sense of self, autonomous of their parents. Within the Chinese-American group, ethnic identification and religion, but not generation, moderated scores on a measure of traditionality of outlook regarding issues of law and order and social equality. We discuss the implications of our findings for recent debates in cross-cultural psychology, including the growing challenge to the individualism-collectivism dimension. 相似文献
