Explaining the association of race and ethnicity with the HIV/AIDS-related attitudes,behaviors and skills of high school students

This study deals with intervening factors such as family composition, religiosity, and HIV/AIDS knowledge in understanding the association of race and ethnicity with HIV/AIDS-related attitudes and behaviors. Data represent Wave 1 of a five-month panel design involving 10th grade students in eight public high schools in Dade County (greater Miami) Florida. Significant differences in attitudes and behaviors were found among racial/ethnic groups. Specifically, Hispanics had more negative attitudes about condom use than blacks or whites. Whites had the most permissive, and blacks the least permissive, sexual attitudes. Hispanics felt least confident and blacks felt most confident about interpersonal sexual skills. Blacks were most likely to have had sexual intercourse, and whites least likely. Religiosity was found to be a significant intervening variable in the less permissive sexual attitudes of both blacks and Hispanics. The most significant implication of this study is that racial/ethnic differences in sexual behavior can be explained more fully by socio-environmental factors such as family structure or religiosity than by knowledge or attitudes. Thus, interventions directed toward minority populations should focus on the development of alternative social environments that would support more positive behaviors. More specifically, extended family, religious youth groups, and other community organizations should be brought into the HIV/AIDS risk-reduction arena.     

知与识：论知识与技术及其关联

技术源于生命,而非基于知识的某种创新或属于知识的分支。物在认识论的层面即理论科学的层面,是经由“起诉”而被纳入“范畴”的存在物。由此,在范畴的序列中只要有物存在,它就是存在物,它不仅符合知识的秩序,而且服从于作为生产的技术将其带向在场的摆置与设定。在技术停摆之处,知识以科学研究的方式为技术打开新的生产视角与进程,而这一生产之完成又伴随着对知识的再创制、再生产。因此,如果将知识理解为存在物层面的知识,即科学知识,那么,技术与知识的关联便凸显为：作为“生产”的技术为存在物层面的理论科学奠基,而对知识的探求,实质上是对技术所擅长的“缘起—招致”的生产方法的探求,即对技术本身之探求。

Mapping social and environmental concerns and the acceptability of genetically modified organisms in the European Union

Simultaneous conflicting attitudes towards an object make both predicting and explaining behaviour a complex endeavour. This paper explores the hypothesis of social ambivalence (so called as well or approach-avoidance conflict) as a phenomenon influencing attitudes towards the environmental effects of the introduction of GMOs (Genetic Modified Organisms). If social ambivalence exists it would be suggestive of an interplay between rational models or behaviour and normative or moral models of behaviour. This paper provides some quantitative analysis based on a representative sample of the European Union, using unique data from the Eurobarometer 58.0 (2002) examining public perceptions of environmental risks. Our findings suggest that GMOs are perceived as having a non-neutral impact on the environmental and social life and that as hypothesized there is evidence of social ambivalence, which appears to be more significant when environmental effects of GM foods are taken into account. Consistently with the hypothesis of interplay between rational and normative models of behaviour, respondents perceive some risks while benefits are not perceived by the public and moral concerns regarding technologies being developed by international corporations are important. A specific type of social ambivalence is found, namely GMO are not accepted for Europeans but they are in less developed countries.     

白蛇故事的演变

白蛇故事是中国四大传说之一。在千年的传承过程中,由于历史的发展、时代的变迁、自然环境与社会环境的差异,白蛇故事以及白蛇的形象产生了不同程度的增补删减。其中唐代《博异志》、宋元话本、冯梦龙《警世恒言》及当代作家李碧华的小说《青蛇》对白蛇故事的记载都极具特色。分析不同时期白蛇故事的变化,可以探求这种变化折射出的不同时代特质和人民内在的追求与思想表达。     

Waste identification diagrams

Value Stream Mapping (VSM) is a very popular tool in lean environments to represent production flows, mapping value stream of a product or family of products, and helps to identify some types of waste. Although very popular, this tool has some limitations as already described in many publications, especially in terms of restrictions in showing most types of waste as well as in its inability to represent various production routes. The purpose of this study is to introduce the waste identification diagram (WID), a new tool to represent production units with its different forms of waste, which overcomes some VSM limitations. The originality of WID comes from the use of its symbols’ dimensions to convey, in a visual and immediate way, relevant information about a production unit. In this paper, WID is applied on a production unit of a lift manufacturer, for testing its performance and comparing it to VSM. The main findings are that WID is in general more effective than VSM in terms of representation of complex production units and in terms of identification of more forms of waste. WID must however overcome some of its limitations such as the lack of information-flow representation and the links to suppliers and clients.

Becoming mother and father in late adoption: a case study

Adoption in Brazil has long been related to practices of not disclosing the child's history and origins, which become a family secret. As a consequence, most couples who apply for adoption prefer newborns. Late adoption is still an uncommon practice and requires a 'family project' which accepts a different family model, new meanings of motherhood and fatherhood, and different ways of building affectionate bonds. It is important to investigate how a man and a woman become parents under those circumstances. This study aimed to follow up the emergence of adoption, motherhood and fatherhood meanings, in the discursive practices involved in the construction of adoptive parenthood in the Brazilian setting. This paper presents important meanings regarding parenthood produced by a couple who adopted two sisters, aged 4 and 5 years. Analysis revealed that to better understand the late adoption process, the meanings that emerge in the discursive practices should be considered. Those meanings pervade and circumscribe the family relationships, influencing how the individuals constitute their roles in the family. It is through the analysis of this dialogical process of construction that it is possible to identify the challenges in late adoption and to unravel the process of constructing affectionate relationships.     

论西方哲学的三次转向

西方哲学史上有三次著名的转向：伦理、认识和后现代。这三次转向与主体有着深刻的关系。伦理的转向将人从自然中独立出来,成就了人的主体;认识论转向形成主客二元对立,将人异化;后现代的转向意在消解理性的主体,实现真实的存在。然而主体的命运究竟何去何从,还有待历史的界说。     

辰州傩戏音乐形态的张力

辰州傩戏（又称土家傩堂戏）现存于湖南湘西土家族地区,是一种介于湘西古老的原始戏剧（以毛古斯为代表）与现代戏曲之间的原始戏剧形态,是戏剧进化时期遗存下来的"活化石"。傩戏形式有傩堂正戏、大戏和小戏之分,音乐曲调古朴,地方特色浓厚,富于原始性张力、世俗性张力,及神秘性张力。
