经络黑箱方法研究及意义

经络的特异实质结构至今尚未探明 ,但已初步研究掌握了经络现象的规律性。古代和现代对于经络的研究常有黑箱方法的一些最基本特征。现代系统科学的黑箱方法 ,不是直接考察经络的内部结构 ,而是利用外部观察和试验来考察经络系统的输入输出及其动态过程 ,研究经络的功能和特性 ,探索其结构和机理的科学方法。现代经络黑箱方法的研究 ,也为经络诊断和治疗提高了精确性和有效性 ,并为经络的实质结构研究奠定理论和技术基础

Racial differences in urban neighboring

Despite mixed expectations generated by existing theories and evidence, this analysis documents clear racial differences in urban neighboring behavior. Using data from a survey of Nashville, Tennessee, residents, we show that blacks interact with their neighbors more often than whites do, and in a greater variety of ways. The only noteworthy similarity between the two groups is the positive impact of neighboring on feelings of community affect. Overall, our results support the view that neighbor relations — like other kinds of informal participation — have helped blacks cope with constrained social opportunities and provided them with access to resources unavailable through formal institutional channels.Revised version of a paper presented at the annual meeting of the American Sociological Association, San Francisco, August 1989.     

从尤瑟夫·海勒的“黑色幽默”文学透析美国社会

廪君巴人“武落钟离山”新考

廪君巴人最早居住的武落钟离山,又名难留山。有些学者认为湖北长阳佷山即巴人发源地武落钟离山。本文从山名、方位、难留山、赤黑二穴、阴阳石、文化遗址、出土文物多方面论证了此观点不能成立。然后,从地名、地貌、民俗、姓氏、县志、古文献、古地图、考古发现等,论证了长阳西部今柳山为武落钟离山所在地。     

浅谈实行建设工程无标底招标利弊及建议

本文分析了无标底招标的特点和利弊,在肯定无标底招标的同时,建议不可盲目实行,提出加强法律、法规建设,规范建筑市场和参与各方的行为是解决问题的关键。     

服装黑白色的永恒特征

一切视觉表象都是由色彩和亮度产生的,那界定形状的轮廓线,是眼睛区分几个在亮度和色彩方面都绝然不同的区域时推导出来的。色彩在服装中的表现力是极强的,是服装款式所不能替代的,特别是色彩的表情作用、象征性、情感表露、意志性的体现,使服装的蕴涵更充实。本文讲述了作为流行色的旋转中轴———黑白色,它没有时段性的流行特征,而是永久的流行色,具有永恒的特征。     

模拟混相驱动态的拟四组分模型

通常模拟混相驱动态采用组分模型,由于组分模型求解工作量大,计算速度慢,要求输入的参数较多,而这些参数很难取全取准,同时组分模型不易被油藏工程师所掌握。因此,介绍了一种模拟混相驱动态的模拟模型,该模型是在黑油模型基础上发展起来的拟四组分模型,它兼有黑油模型和多组分模型的某些优点,如黑油模型的稳定性好和计算速度快、组分模型的可模拟凝析气藏和混相驱等;给出了数学模型及各种物理参数以及混相流体性质的处理方法。该模型还以SPE为例进行计算,结果与SPE的结果一致,从而验证了本模型的可靠性。     

Black men teaching: toward a theory of social isolation in organizations

ABSTRACT

While there continues to be increasing research about Black male teachers’ school-based experiences, there is less empirical evidence on the variation in these experiences for this subgroup. Drawing on Kanter’s Theory of Numbers and Group Composition, the researcher used the qualitative method to compare the perceptions of Black male teachers in schools that employ just one Black male teacher versus schools with larger numbers of Black male teachers. A theory of social isolation in organizations is proposed to explain differences in the variation of school-based experiences for Black male teachers. When compared to Black men in schools with larger percentages of Black male teachers on the faculty, those Black men who were the only Black male teachers on their faculty were more likely to describe feeling socially isolated and disconnected from their colleagues.
