The fertility related behavior of Mexican American adolescents

Data from a clinic sample of pregnant adolescents are analyzed for differences in fertility related variables between Mexican American and non Mexican. The independent variables are birthplace, ethnicity, and exposure to United States culture of Mexican and non Mexican adolescents. The dependent variables are talking about sex, pregnancy, birth control, hearing about birth control, and use of birth control. The data support the hypothesis that in the process of acculturation the fertility related behavior of immigrant Mexican adolescent females is affected by the indigenous United States Mexican culture rather than by United States Anglo culture. Implications for delivery of services are discussed. The delivery of fertility related services should take into account the cultural preferences of Mexican women, and should not involve coercion from legal or medical authorities. While liberation of Mexican American women, and accompanying changes in childbearing patterns may be desirable, these efforts should originate within the Mexican American community. Data is presented in tables on selected sample and subsample characteristics and compares fertility behaviors across ethnic groups, including Anglo, Black, US non-Mexican, and US Mexican.     

Concurrent schedule assessment of food preference in cows

Six dairy cows (Bos taurus) were trained on several pairs of concurrent variable-interval schedules with different types of food available on each alternative. The required response was a plate press made by the animal's muzzle. Performance generally replicated that found with other species. The generalized matching law accounted for the preference data, showing that food preference could be quantitatively analyzed as a special case of response bias. The preference functions showed that the response- and time-allocation ratios were not as extreme as obtained reinforcement rate ratios (undermatching).     

新康德主义

新康德主义一词,是用来说明1870年至1920年间,遍及全德国的一种多少有些相似的哲学活动;它们都强烈地反对非理性主义与思辨的自然主义,确信只有回到康德的方法与精神上去,哲学才可能成为一种“科学”;除此之外,它们没有多少共同之处。这些哲学活动是实现了康德的预言,即一百年内他的哲学会得到复兴。由于康德哲学的复杂性与内部矛盾,新康德主义者从哥尼斯堡的圣人那里取来的经并不一样,他们主张不一,众说纷纭。到十九世纪末,新康德主义者之间,和在其初期第一代的康德主义者活     

Stimulus redundancy and immediate recall

This study examined immediate recall in two stimulus prefix and two stimulus suffix conditions and in a condition that combined a prefix and suffix. Suffixes and the combination of a prefix with a suffix interfered more with recall overall than did prefixes. Performance in each of the conditions that included a prefix was significantly better overall than in appropriate control conditions, in which interference was augmented by a redundant element in recall. It was suggested that prefixes and suffixes lie operationally on a continuum and that their effects result from the subject's inability to dissociate the redundant element from the memory series. However, the location of redundancy imposes different processing requirements that differentially influence recall.     

雅斯贝尔斯的海德格尔批判:思维的傲慢

一、比较方法的意义与界限假定一个人严肃地对待哲学,那么任何试图比较卡尔.雅斯贝尔斯与马丁.海德格尔的作法都难免显得十分可疑。也许,甚至将比较方法列入哲学工具之标准目录也显得可疑,但是,那些使用这种方法的人们却常为这种方法所提供的巨大的解释收益而辩护。当然,对于我     

苏联科学院的《哲学问题》杂志

中华人民共和国的各界人士对现代苏联社会生活各个领域中正在发生着的那些变化显然是有所了解的。苏共中央1985年4月全会的著名决议、苏共27大和苏共中央其他一些全会的文件提出了苏联发展的战略方针,苏共中央总书记M.C.戈尔巴乔夫在他的许多讲话中进一步阐发了这一战略方针。其中对苏联社会当前发展阶段的实质做了如下的理
