通过尘障后的激光束特征

从辐射亮度方程出发,推导了在大粒子近似条件下,激光束通过尘障以后约化通量密度和漫射通量密度的表达式,并在四个常用激光波长上作了数值计算.结果表明,当散射粒子浓度较大时,尘障后表面上的漫射通量密度通常比约化通量密度高很多,且散布在较宽的范围内.随着光束远离尘障,漫射通量密度迅速减小,约化通量密度重新占据主导地位.     

管理沟通在高校图书馆工作中的应用

高校图书馆在高校师生心目中应有极其重要的位置,在高校的教学、科研工作中应有极其重要的作用,但现实与期望总会有一定的差距。面对差距,高校图书馆内部应充分应用管理沟通的原理与方法,作好图书馆领导层与馆员之间、馆员与馆员之间以及馆员与读者之间的沟通和交流,处理好与各方的关系,弥补来自各方的认识偏差和自身工作的不足,提升高校图书馆的声望与地位。     

网络交往中真实性的社会学分析

在网络交往中,其交往媒介的表意性、交往主体的平等性、交往互动的开放性、交往管理的规范性都是不同于现实的社会交往的,其交往过程中不仅有虚拟性的一面,而且也有其真实性的一面。网络交往中的真实性对我们具有升华社会交往、促进人的社会化、丰富社会日常生活等方面的意义。     

儒、释、道的人际交往观比较研究

人是自然属性和社会属性高度集中的统一体,社会生产关系是决定人际交往关系的决定因素。人们在社会生产生活中必然发生某种关系,可统称为人际关系或社会关系。儒家、佛教、道教均有其各自的人际交往理论和实践,认真总结儒、释、道三家人际交往的经验教训,是建设具有中国特色社会主义新文化的时代要求。     

Unexpected but authentic use of an ethnically–marked dialect

Recent work on language crossing in the U.S. has examined the temporary appropriation of African American Vernacular English by white youth in an effort to participate in the current popularity and prestige of hip–hop culture, or in order to highlight racial boundaries. While such verbal behavior probably encompasses most white use of AAVE, it is not the only way in which whites (or other non–blacks) can use the variety. This paper presents a case study of the language of a 23 year old white female who makes consistent use of many distinctive linguistic features associated with AAVE. I argue that the interaction of ideologies of race, class, localness and language allow her to be considered an ingroup member despite her biographical race. This suggests that there is a tension between academic linguistic theory and actual speaker practice in assigning authenticity to individuals, and I conclude that language ideologies and other forms of qualitative evidence should be taken into account by sociolinguists looking at the link between language and race.     

文艺社会学批评理论的新向度--"传播论"批评

2 0世纪 90年代 ,曾有论者提出文艺社会学批评理论要走出古典形态 ,开拓现代形态 ,建立“中介论”的文艺社会学批评理论。但从文艺学理论构架出发 ,结合当代艺术文化状态进行反思 ,“中介论”的文艺社会学批评理论存在局限性 ,而建构“传播论”向度的文艺社会学批评理论 ,即可在本体论结构上实现批评理论向度的新拓展。

Empathy and professional attitude in social workers and non-trained aides

The purpose of this study was to investigate empathic communication and professional attitude in vocational groups representing different levels of professional training. A further aim was to elucidate some aspects of the impact of the clients. Four groups of professionals participated, three with degrees as social workers and one with only short professional training. Three groups worked with committed drug addicts, one group with somatically ill patients. The 110 subjects were tested with a video-test of professional attitude and empathic communication. Different response patterns were found in the different groups. The group with short training had the highest proportion of unprofessional responses. The group of social workers working with somatically ill patients showed the highest amount of empathic communication. Furthermore, there was a distinction among the kind of unprofessional responses used by the different groups. Hypotheses on the causes of these differences and implications for future research are discussed.

A LOTTO SYSTEMS PROBLEM

A Lotto Systems bet allows the player to nominate n numbers from which (s)he believes the winning six numbers will be drawn, and to bet on all combinations of six of these n numbers. Assume that the winning six numbers come from the nominated n. How many combinations must be entered to guarantee that one combination will include at least five of the winning six numbers? The problem is generalized in this paper, and the method of simulated annealing is used to find solutions for various situations. The case where two supplementary numbers are drawn after the initial six winning numbers is also considered.
