《周易》蕴涵的自然哲学思想,可谓是一种以生命为隐喻,宇宙论、本体论、价值论统一的生成哲学,它基于道德实践与认识实践统一的生命实践。文章根据《周易》"经"、"传"本身之内涵,按现代哲学表述方法,从源于道德之宇宙论,三才圆通之本体论,知行不二之实践论,生成整体之方法论等方面,阐明中国式自然哲学的特性与意义。指出正是这种独特的自然哲学,不仅开启了中国文化超越的价值之源,为中国古代科学提供了形而上学基础,而且应在21世纪伟大历史转型和中西对话中,共同创造人类不同文化"殊途同归"、"和而不同"的世界生成之序。  相似文献

In turbulent business times, organizations have sought to become more agile. Organizational agility has been asserted to require workforce agility, but thus far, little focus has been given to workers. Traditionally, salespeople have sought ways to differentiate themselves and create advantage for customers. This paper asserts that, in order to continue this tradition of differentiation and advantage, salespeople must engage in agility thinking. Agility has been studied as it applies to manufacturing processes and other firm activities. Agile salespeople have a mental dexterity at the point of customer contact. They are quick to observe opportunities and are able to anticipate customers’ ever-changing needs, wants, and preferences. This paper presents a framework for agility selling, applying concepts from the agility manufacturing literature and proffering distinct characteristics of sales force agility.  相似文献

Recent studies demonstrate that individuals and populations (at the scale of nations) exhibiting slower life history (LH) speeds are more differentiated amongst themselves with respect to the components of life history. Faster life history individuals and populations are more integrated by comparison. This phenomenon, termed strategic differentiation–integration effort (SD–IE), has not yet been tested on a national scale, however, which is an important remaining step in establishing its generalizability at different levels of aggregation among humans. SD–IE was tested with data on five LH variables from the fifty states of the US. Effects supportive of the SD–IE hypothesis were found in all LH variables, with an average effect magnitude slightly larger than that found in studies of SD–IE at the individual differences level. This is putatively attributed to population stratification, due to the varied racial make-up of the population in the US, including European, African, Native American, and Asian ancestries from multiple countries. This study indicates that SD–IE is a generalizable phenomenon occurring at various levels of aggregation.  相似文献

Relatively little is known about the integration of people's fear-related dispositions and their expectations about stressful events. This research used information integration theory to examine how participants’ anxiety sensitivity and event expectancy are integrated to determine their social anxiety. Three studies were conducted—two with university students and one with anxiety clinic patients—in which participants were presented with multiple scenarios of a socially embarrassing event, each representing a different degree of event probability, from which subjective expectancies were derived. Independent variables included anxiety sensitivity (low, moderate, high) and event expectancy (low, medium, high, no probability information). Participants were asked to indicate their anxiety (dependent measure) in each expectancy condition in this 3 × 4 mixed, quasi-experimental design. The results of all three studies strongly suggest that anxiety sensitivity and event expectancy are integrated additively to produce social anxiety. Additional results and their implications for the treatment of anxiety-related disorders are also discussed.  相似文献

IntroductionThe present study aims to evaluate the influence of intellectual deficiency on the lifestyle of brothers and sisters.ObjectiveThe objective is to determine whether or not a child's intellectual deficiency has an influence on the nature of the fraternal relationship. We studied the functionality of the familial typology, the feeling of social integration, and the degree of depression in brothers and sisters of children with intellectual disability.MethodThis research was carried out with 34 brothers and sisters of children faced with intellectual disabilities, aged between 6 and 12 years old, and the results were compared with those collected from a test group of 24 children.ResultsThe comparative study shows little differences between siblings and families confronted to intellectual disability and those who are not. The nature of the fraternal relationships differ however as the modality of proximity and conflicts are less expressed by siblings of children faced with intellectual disabilities. Furthermore the correlational study stresses the importance of siblings’ rivalry, the feeling of social integration, and the degree of depression.ConclusionWith these results now uncover risk and protection factors to children confronted to intellectual disabilities among their siblings  相似文献

ABSTRACT

The integration of the sameness or difference of two unconscious stimuli occurs and affects behaviour without subjective visual consciousness. Yet, intermittent stimulus awareness or a process simpler than integration could also account for these results. In a masked go/no-go task, participants provided or withheld a response based on the same/different relation of two stimuli. Post-trial performance on a discrimination task was used to classify invisible stimuli, providing an objective criterion of awareness. Stimulus pairs with a No-go-associated relation showed reduced and slower responding even when those stimuli were incorrectly discriminated and presumably unconscious. Due to the large set of stimuli, this effect is unlikely to be due to response mapping or action triggers. The integration of the relation of discrete stimuli is a cognitive function that is not dependent upon visual awareness, in the form of conscious identification, to occur.  相似文献

ABSTRACT

In order to efficiently control our actions, stimuli and responses made to them are stored and integrated into event files. This integration is not restricted to relevant stimuli. Even irrelevant stimuli or features that co-occur at responding can be integrated with the response. In the presence of only one irrelevant feature, binding effects for that feature are generally observed. In the presence of more than one irrelevant features, empirical evidence is inconsistent. The present experiments tested feature-response binding effects for irrelevant features when more than one irrelevant feature was present. In two experiments feature-response binding effects for three irrelevant features (colour, shape, and location) were tested in a block-wise manner. In each block one feature was orthogonally varied to the response while the others were held constant (Experiment 1) or always changed (Experiment 2). Significant binding effects were observed for each of three features when the other two were held constant (Exp. 1). However, when the other two features were varied, significant binding effects were only observed for colour and location, but not for shape (Exp. 2). The results suggest that strength of feature-response binding effects is influenced by the variation of simultaneously presented features.  相似文献

探求内向整流型钾离子通道1(GIRK1)与宫颈癌发生发展的关系.利用RT-PCR及免疫组织化学技术检测GIRK1 mRNA及蛋白在15例正常宫颈和30例宫颈癌组织细胞中的表达.GIRK1 mRNA在宫颈癌组织中的表达高于在正常宫颈组织中的表达,差异有统计学意义(P〈0.01);GIRK1蛋白在宫颈癌组织中的阳性表达率为100%,在正常宫颈组织中的阳性表达率为20%,两者差异有统计学意义(P〈0.01).GIRK1 mRNA及蛋白在宫颈癌组织中呈高表达,可能与宫颈癌的发生及发展有关.  相似文献

长期以来以专科划分为主的医疗发展方式确实促进了现代医学的进步.然而,人是一个整体不应该被割裂对待.所以,这种医学发展趋势应该加以控制,否则必然会阻碍医学事业的健康发展.另外,如果只关注局部治疗想要取得突破已经越来越难.因此,整合临床医学势在必行.本文分别从阻塞性睡眠呼吸暂停的病因、临床表现(包括合并症)及诊断和治疗三个方面阐述了只有全面进行医学整合才能提高阻塞性睡眠呼吸暂停的整体防控水平.  相似文献
