应激对大鼠行为和部分脑区谷氨酸含量的影响

以旷场试验法测定动物在急、慢性躯体性和心理性应激时的行为变化,以快速断头冷冻匀浆法,用ＨＩＴＡＣＨＩ－８３５氨基酸分析仪测定应激各期视皮层、海马、下丘脑、小脑谷氨酸含量。并对正常动物经侧脑室微量注射Ｌ－ＡＰ４后观察行为变化。结果显示,急性应激期动物行为活动增加,慢性应激期减少：应激时,大鼠部分脑区的谷氨酸含量与对照组相比在不同时期呈显著性差异;侧脑室微量注射Ｌ－ＡＰ４提示行为活动减弱可能与脑内Ｇｌｕ系统的活动有关。     

Islam as an ethical tradition of international relations

This article explores the ethical traditions of Islam in order to examine its potential as a source that would help precipitate ethical and peaceful, as opposed to political and conflictual, relations between nations, faiths, and cultural groups. While using philosophical and ethical categories borrowed from the Western epistemes, this paper in a way reintroduces Islam as an ethical tradition. Given the significance that Islamic sentiments and Islamic symbolism have for a billion people and over fifty nation states, this paper recommends the inclusion of Islamic traditions in discourses whose concern is the proliferation of ethical consideration in international and intercultural relations. Having said that, the paper proceeds to elaborate foundations for an Islamic ethic of international relations.     

Perceived life quality of older and younger tibetans

Tibetans have enjoyed a reputation for contentment and a jovial disposition. This study examines the extent to which this positive outlook on life persists despite their 25-year stay as refugees in India, and the transferability of this positive outlook to first-generation, Indian-born Tibetans. With this in mind, older Tibetan refugees (N = 45) and younger Tibetan refugees (N = 45) residing in Himachal Pradesh in India were administered the Life Quality Scale (Q.O.L.). As expected, younger Tibetan refugees shared significant characteristics on the Q.O.L. scale with older Tibetans. Similarities and differences in the outlook of the two age groups are examined.Portions of this paper were presented at the annual meeting of the International Society for Intercultural Education, Training, and Research in Montreal in May 1987.The author wishes to thank Sherab Gyatso of Tibetans' Childrens Village, a school in Dharamsala, for his help in collecting the data.     

Effects of fasting on visual flicker fusion

Two experiments are reported which investigated the effects of fasting on visual flicker fusion (VFF). In Exp. 1 the VFF of 40 undergraduate students, 20 men and 20 women, whose mean age was 22.5 yr., was measured in nonfasting conditions 1 to 2 weeks before and in fasting conditions during the Muslim fasting month of Ramadan. In Exp. 2 the VFF of a comparable group of 15 men and 15 women, whose mean age was 23.2 yr., was measured in a different month in both fasting and nonfasting conditions. Subjects were assigned randomly to these two conditions. Analysis shows that fasting reduced VFF significantly in both experiments. This finding indicates that fasting is likely to reduce perceptual sensitivity. The results were explained in terms of fatigue and physical exhaustion effects produced by fasting.     

The cloze technique in Arabic: Words or semantic units?

The wide gap between written and spoken variants of the Arabic language turns reading comprehension into a criterion of formal learning. The cloze technique for assessing reading comprehension is a promising tool, but it involves a decision as to whether the elision of complete words, as in English, is to be preferred to the elision of semantic units that are whole words in English but compounded in Arabic and certain other languages. In effect, the question is whether Arabic is decoded mainly by way of perceptual or semantic units. Omitted words or semantic units within words, at the rate of every fifth, sixth, or seventh unit, were replaced by 584 Arab pupils in the fifth, sixth, or seventh grades of Arab schools in Israel. Age and frequency-of-omission trends tended to favor the whole-word elision method, while presumed difficulty of passage agreed with the semantic-unit method. The two methods were shown to be equally valid by a criterion of teacher grades. In sum, the cloze method appears well adapted to Arabic, and there is no apparent reason to abandon the whole-word method used with English and other languages.The generous help of the Institute of Research for Arab Education and Development at the University of Haifa is gratefully acknowleged. The paper was completed while the first author was on sabbatical leave at the University of South Florida, Tampa, Florida.     

Does retinal size have a unique correlate in perceived size?

Subjects estimated the size and distance of a single electroluminescent disc in the absence of distance cues and without the use of visual comparators. For different groups of Ss the disc subtended a visual angle of 1, 2, 4, or 8 deg. The size estimates varied directly with visual angle and the distance estimates varied inversely with visual angle. These results were considered in relation to the question of whether or not retinal size hasa direct correlate in perceived size.

Comparison of Offender and Non-offender Young Men to Setting Goals for Life and Attributing Meaning to Life

The main goal of the present study is to compare male offenders and non-offenders in terms of how they attribute meaning to life and set life goals. The samples were chosen from among offenders (n = 50) and non-offenders (n = 50) who were between ages 19–26. Mixed method was used in this study. The scale of setting life goals and interview form were used to collect data. To analysis of the data, the content analysis technique and t test and were used. Findings of the present study show that offenders tend to have troubles setting life goals when compared to non-offenders. Furthermore, the results of this study could be used in rehabilitating offenders and preventing those at risk of committing criminal acts from doing so.
