Design and implementation of a program for AIDS prevention in female prostitutes

The Companeros model of HIV infection prevention in Ciudad Juarez, Mexico, is presented as conceived by the National Institute of Drug Abuse (NIDA). 518 women who were IV drug users, sexual partners of drug addicts, or prostitutes were requested to participate, and 232 consented. Initial and follow-up AIDS assessments were utilized along with an assessment of sociodemographic variables, including knowledge, sexual behavior, use and abuse of drugs, and previous health history. Educative sessions about AIDs and sexually transmitted diseases (STDs) included group discussions and interaction, video watching, personal experiences, and sociodramas. 61% of prostitutes were 29, 12.6% were 13-19 years old, 31.1% were aged 30-39, and 8.9% were 40. 11% had no formal education, 58% had 6 years of primary and part of 3 years of secondary education, only 18.6% completed secondary education; and 13% had higher education. 19% lived in a hotel or shelter. Family disintegration reached 44%; these women did not live with their children. Only 5.2% thought they had excellent health, 51% said they had good health, 31% stated they had average health, and 12% admitted having had health problems. 14.6% had genital ulcers, 1.3% had herpes, 15% had gonorrhea, and 10% had syphilis. Since IV drug use among these women was almost nonexistent sexual relations constituted the principal risk factor. Responses to a questionnaire showed that the most frequent sexual behavior was vaginal penetration followed by fellatio; anal penetration was less common. 34.9% of the women practiced fellatio without protection, 16.3% had anal intercourse without protection. The proportion of AIDS cases in Mexico in women of reproductive age was growing at an exponential rate, possible because of misinformation about AIDS, a history of STDs, and a low rate of condom use.     

心身问题与心灵哲学

第9届维特根斯坦国际专题讨论会的主题是心灵哲学(philosophy of mind,或译心智哲学)和心理学哲学。详细地讨论过的问题包括:心身问题、心灵哲学的传统问题和心理学哲学。 1.心身问题什么是心身问题?“心灵”(mind)一词有多种非常不同的用法,这一事实导致了现代讨论中的某种混乱。对这个词,我们至少可以区分出五种不同的用法,因此心身问题至少有五种意义。 (1)我们可以象笛卡儿使用“mens”一词那样使用“心灵”一词,让它指称具有心理属性的东西,亦即指称那种能思想,能感知,能相信和能欲求的东西。在这种情况下,我们通常是用“心灵”这个词意指“人”这个词所意指的东西,因而该词表示的就是你和我这样一些实     

甘岑的自然演绎演算

迄今为止,我们所主要讨论的逻辑演算,即用公理方法处理的狭谓词演算,标志着把数学方法运用于逻辑获得了显著的成功。这种演算的形式上的简易是令人称道的,从纯粹数学的观点看,它可以同公理化的射影几何及抽象群论这一类数学观念的完满体现的学科相媲美。此外,作为应用于研究演绎系     

判断和选择中的认知错觉

人类的错误为研究人类智能的结构和功能提供了有价值的资料。对于记忆的研究多是建立在遗忘的基础上,对知觉的研究常常基于识别力衰退,对于语言和思维的研究已经揭示了失言。关于人类错误的研究格外重要,因为它表明了人类智力的某些局限,它时常暴露出隐藏在人们行为之下的规律和机制,它常常提示出可以改善人们表现的方式。错觉是一种特殊的错误,它特别令人困惑,因为人们造成的这种错误始终具有迷惑力,甚至当人们已彻底认识到这是一种错误时亦然。例如,我们会感到在图1中右边的线     

共产主义实验在苏联

1.斯大林个人扭曲了的共产主义意识形态“斯大林主义”,是苏联官方理论家从不使用的一个术语。而且,它一般也并没有被人们广泛地当作马克思-列宁主义来运用。有时候,斯大林主义被误解为是马列主义的一种扩大或发展。实际上,斯大林主义倒可以看作是从马列主义中派生出来并且背离了马列主义的,它(直到1953年斯大林去世时     

民族心理结构——系统初探

用系统论方法研究民族心理,把民族心理看作一个结构——系统,首先应该搞清楚这个结构——系统是由哪些因素构成的?这些因素是怎样排列的?它们相互关系的性质如何?实际上,这都是有紧密联系的问题     

解释学

一、从1966到1976年,是解释学尤其是“哲学解释学”内部急剧发展的十年,是它同当代各种思想流派对话、进行活跃的“解释的论战”的十年。我们可以用P.利科尔在《论解释》一书(1965)中的一句话,即“语言的问题和原文(或译为本文——译者)解释的问题已经变为当代思想的十字路口”,来说明这整个十年的情况。除了传统的解释学、神学的解释学和H.-G.加达默尔的哲学解释学以外,其他思想运动也一一涌现了出来——例如结构主义、符号学、拉康的以语言为中心的弗洛伊德精神分析学、福柯以及对尼采的研究。后面这些研究的发展使国际上认为法国在语言理论和原文解释理论方面是大步前进的研究中心。当然,有     

解释学

四、要记述1966年至1976年之间解释学发展的热门时期,困难的确不小。限于篇幅,我们只能谈一下:(1)一些主要的关于解释学的讨论会;(2)几种关心解释学问题的杂志;(3)圣经解释学在这一时期的发展;(4)一般性的和有关文化方面的解释学在这一时期的发展;(5)解释学向其他知识领域的渗透和它与这些领域的交流情况。 (1)讨论会在这一时期举行了许多关于解释学或与解释学有关的会议,举行这些会议的地方或部门有:德鲁大学,约翰斯·霍普金斯大学,罗     

咖啡因与心理紧张对血压的影响:交叉文化的比较研究

引言饮用含有咖啡因的饮料已遍及全球。大多数西方国家如美、英、法,习惯饮用咖啡;大多数东方国家如中、印、日,习惯用茶。还有一些国家喜欢饮含少量咖啡因的可可,“瓜拉那”等。据估计每年世界咖啡消费量已超过400万吨(Rokeitson,1978)。茶在中国的消费,也从1965年的43000吨,上升至1976年的139000吨(“中国经济年鉴”,1981)。为什么全世界范围内这样普遍地饮用咖啡和茶呢?原因是这些饮料中的咖啡因能提神解劳,提高感觉敏锐度和反应速度,使思路畅通,延长智力劳动的时间。如Nash(1962)的研究表明,咖啡因有助于成对联想学习,听觉材料的及时回忆,以及完成不完整的句子。但是近年来人们发现,咖啡因对人体有有害的作用。摄入咖啡因后,其中的甲基黄嘌呤     

Reaction time methods in the study of motor programming: the precuing of hand, digit, and duration

Recent reaction time analysis of motor programming has utilized a precue stimulus that provides advance information about some or all of the attributes for the upcoming motor response. This kind of precue typically confounds the number of remaining stimuli with the motoric processes under investigation (Zelaznik, 1978). In Experiments 1 and 2 the precuing of hand, digit, and duration of a key press response was manipulated. A new precuing procedure was utilized that does not confound the number of stimuli with the motoric processes under investigation. The findings of Experiments 1 and 2 demonstrate that none of the advance information was helpful in reducing reaction time and as such, suggest that these features of movement are not selected in any particular order. Experiment 3 compared this new method of precuing to the other, traditional method. The results of this experiment suggested that there is parallel processing of the perceptual and motor mental operations in this reaction-time task, since there was an underadditive interaction between the number of stimulus response alternatives and the non-precued movement dimensions. This paper highlights problems inherent in the utilization of precursing methods to understand motor programming processes. It appears that a better understanding about the variables involved in movement control is necessary before examining the order of selection of those variables.
