In this paper we propose an approach to vagueness characterised by two features. The first one is philosophical: we move along
a Kantian path emphasizing the knowing subject’s conceptual apparatus. The second one is formal: to face vagueness, and our
philosophical view on it, we propose to use topology and formal topology. We show that the Kantian and the topological features
joined together allow us an atypical, but promising, way of considering vagueness. 相似文献

从系统论看肿瘤的生物靶向性治疗 总被引:2,自引:0,他引:2
邓远美 《医学与哲学(人文社会医学版)》2008,29(1):66-67
肿瘤的生物靶向性治疗是恶性肿瘤治疗的新方法,其试图通过在基因水平上调节与肿瘤发生、发展有密切联系的生命物质来达到治愈肿瘤的目的。但临床运用中,生物靶向性治疗的疗效与我们的想象相去甚远。本文运用系统论的观点,分析目前生物靶向性治疗中存在的问题及寻求可能解决的方法。 相似文献

Adolescents spend a substantial amount of time using social networking sites (SNSs); however, little is known regarding whether such use is associated with indicators of adjustment. The present study employed a multidimensional measure of SNS use to investigate the link between Australian adolescent SNS use and indicators of adjustment. Youth (N = 1,819, 55% female) from 34 diverse high schools across Western Australia were surveyed. The results showed that frequency of SNS use was linked to higher social self‐concept while investment in SNSs was associated with lower self‐esteem and higher depressed mood. Furthermore, having an SNS was linked to more negative indicators for female adolescents compared with male adolescents, although the link between frequency of use and investment in SNSs to indicators of adjustment was not moderated by gender. The present study highlights the complexity of the relationship between adolescent SNS use and indicators of adjustment, and offers insight into the diverse types of adolescent use of SNSs. 相似文献

研究探讨了585名7、9、11岁的小学儿童在诚实原则和集体主义价值观冲突的真实情境下的道德行为及其与道德观念的相关。结果表明,在诚实原则和集体主义价值观冲突情境下,小学儿童的道德行为主要受到诚实原则的支配,表现为:为集体说谎行为发生率都很低;随着年龄的增长,小学儿童的为集体说谎行为的发生率显著增高;小学儿童的为集体说谎行为不存在性别差异;7岁、9岁儿童的为集体说谎行为与集体观念无关,11岁儿童的为集体说谎行为与集体观念显著正相关。 相似文献

While five-month-old infants show orientation-specific sensitivity to changes in the motion and occlusion patterns of human point-light displays, it is not known whether infants are capable of binding a human representation to these displays. Furthermore, it has been suggested that infants do not encode the same physical properties for humans and material objects. To explore these issues we tested whether infants would selectively apply the principle of solidity to upright human displays. In the first experiment infants aged six and nine months were repeatedly shown a human point-light display walking across a computer screen up to 10 times or until habituated. Next, they were repeatedly shown the walking display passing behind an in-depth representation of a table, and finally they were shown the human display appearing to pass through the table top in violation of the solidity of the hidden human form. Both six- and nine-month-old infants showed significantly greater recovery of attention to this final phase. This suggests that infants are able to bind a solid vertical form to human motion. In two further control experiments we presented displays that contained similar patterns of motion but were not perceived by adults as human. Six- and nine-month-old infants did not show recovery of attention when a scrambled display or an inverted human display passed through the table. Thus, the binding of a solid human form to a display in only seems to occur for upright human motion. The paper considers the implications of these findings in relation to theories of infants' developing conceptions of objects, humans and animals. 相似文献

A connectionist model of the balance scale task is presented which exhibits developmental transitions between ‘Rule I’ and ‘Rule II’ behavior [Siegler, R. S. (1976). Three aspects of cognitive development. Cognitive Psychology,8, 481–520.] as well as the ‘catastrophe flags’ seen in data from Jansen and van der Maas [Jansen, B. R. J., & van der Maas, H. L. J. (2001). Evidence for the phase transition from Rule I to Rule II on the balance scale task. Developmental Review, 21, 450–494]. The model extends a connectionist model of this task [McClelland, J. L. (1989). Parallel distributed processing: Implications for cognition and development. In R. G. M. Morris (Ed.), Parallel distributed processing: Implications for psychology and neurobiology (pp. 8–45). Oxford: Clarendon Press] by introducing intrinsic variability into processing and by allowing the network to adapt during testing in response to its own outputs. The simulations direct attention to several aspects of the experimental data indicating that children generally show gradual change in sensitivity to the distance dimension on the balance scale. While a few children show larger changes than are characteristic of the model, its ability to account for nearly all of the data using continuous processes is consistent with the view that the transition from Rule I to Rule II behavior is typically continuous rather than discrete in nature. 相似文献

Not a lot of work on theistic arguments has been devoted to drawing connections between a necessary being and theistic properties.
In this paper, I identify novel paths from a necessary being to certain theistic properties: volition, infinite power, infinite
knowledge, and infinite goodness. The steps in those paths are an outline for future work on what William Rowe (The Cosmological
Argument, 1975, p. 6) has called “stage II” of the cosmological argument. 相似文献
