全球生命伦理学

探讨生命伦理学的起源,并阐述了不同理论支持者的观点,发现无论准确的生命伦理学历史起源是什么,目前生命伦理学已经变成了一种真正的全球现象。它在全世界具有重要的意义,因为人类不仅仅是欧洲人或亚洲人,也是世界公民和一个全球道德共同体的成员。生命伦理学对任何地方、任何人都是重要的,并不是因为它是"拿来"的,而是因为它提供了一个普遍的框架去解释和管理正在经历的变化,这个变化包括了目前所有的国家和文化。然而,这个框架的解释和应用必须依据本土环境。因此,现代生命伦理学具有全球性和本土特征的特点。     

信息社会中二维的科学的出现

一、社会的三个高度越来越多的人认识到,有些国家,首先是美国和其他西方国家,正处在具有重要意义的某种独特历史的叉路口。这一叉路口通常被说成是从工业社会到后工业社会的过渡阶段。其意义之重大可与先前发生的从前工业社会向工业社会的巨大社会变迁相比拟。尽管多数西方     

Relative mislocalization of briefly presented stimuli in the retinal periphery

We studied the ability to localize flashed stimuli, using a relative judgment task. When observers are asked to localize the peripheral position of a probe with respect to the midposition of a spatially extended comparison stimulus, they tend to judge the probe as being more toward the periphery than is the midposition of the comparison stimulus. We report seven experiments in which this novel phenomenon was explored. They reveal that the mislocalization occurs only when the probe and the comparison stimulus are presented in succession, independent of whether the probe or the comparison stimulus comes first (Experiment 1). The size of the mislocalization is dependent on the stimulus onset asynchrony (Experiment 2) and on the eccentricity of presentation (Experiment 3). In addition, the illusion also occurs in an absolute judgment task, which links mislocalization with the general tendency to judge peripherally presented stimuli as being more foveal than they actually are (Experiment 4). The last three experiments reveal that relative mislocalization is affected by the amount of spatial extension of the comparison stimulus (Experiment 5) and by its structure (Experiments 6 and 7). This pattern of results allows us to evaluate possible explanations of the illusion and to relate it to comparable tendencies observed in eye movement behavior. It is concluded that the system in charge of the guidance of saccadic eye movements is also the system that provides the metric in perceived visual space.     

Sexuality attitudes and behaviors of self-described very religious urban students in middle school

Data from a survey of 869 students aged 11 to 15 years and attending six urban middle schools were analyzed to identify differences in sex attitudes and behaviors between self-reported very religious students and their less religious peers. The two groups were demographically similar. They differed on only two attitude items, one suggesting that intercourse was a normal part of teenage dating and the other suggesting intercourse was alright if the two people were in love. The groups did not differ in their estimation of their peers' sexual activity or attitude or in terms of their own intercourse behavior or future intentions.     

The relevance of attachment theory to a contemporary Jungian view of the internal world: internal working models, implicit memory and internal objects

In this paper I examine the various meanings of the term 'internal object' and the differences between various theoretical models for the formation of internal objects. I suggest that the idea in attachment theory of 'internal working models' emphasizes the internal world as one consisting of unconscious internalized patterns of emotional relationships. The term 'internal object' lacks this clarity and the different meanings it carries within differing theoretical frameworks are a source of confusion. I describe the role implicit memory plays in the formation of 'internal working model's and suggest that these offer us an alternative explanation for unconscious fantasy and for object relationships to that of instinctual drives. This model is then brought to bear on contemporary Jungian concepts of the internal world, with a suggestion that, seen in this light, Jung's formulation of the concept of the complex has many features in common with the 'internal working model' of attachment theory.     

The peripheral drift illusion: a motion illusion in the visual periphery

Circularly repeating patches containing sawtooth luminance gradients produce a sensation of motion when viewed in the periphery. Illusory motion is perceived in a dark-to-light direction, but only when one's gaze is directed to different locations around the stimulus, a point outside the display is fixated and the observer blinks, or when the stimulus is sequentially displayed at different locations whilst the observer fixates one point. We propose that the illusion is produced by the interaction of three factors: (i) introducing transients as a result of eye movements or blinks; (ii) differing latencies in the processing of luminance; and (iii) spatiotemporal integration of the differing luminance signals in the periphery.     

Amount of reward has opposite effects on the discounting of delayed and probabilistic outcomes

Previous research has shown that the value of large future rewards is discounted less steeply than is the value of small future rewards. These experiments extended this line of research to probabilistic rewards. Two experiments replicated the standard findings for delayed rewards but demonstrated that amount has an opposite effect on the discounting of probabilistic rewards. That is, large probabilistic amounts were discounted at the same or higher rates than small amounts. Although amount had opposite effects on the discounting of delayed and probabilistic rewards, nevertheless, the same form of mathematical function accurately described discounting of both types of reward. The findings suggest that fundamentally similar, but not identical, processes are involved in decision making regarding delayed and probabilistic rewards. The implications of these findings for impulsivity and self-control are discussed.     

Time perspective and sleep problems

In this study of 137 university students, we examined the relationships among the five dimensions of the Zimbardo Time Perspective Inventory and three scales that measure aspects of sleep problems. All of the Zimbardo Inventory dimensions correlated significantly with each of the sleep problem-related scales. These data suggest that concern about time, regardless of the specific nature of individuals' time perspective, and certain sleep problems are significantly related.     

Ethnicity and bruxism

Distributions of students of four ethnic groups were statistically significantly different. 106 African-American students reported the lowest incidence of self-reported bruxism (9.4%), 452 Asian students the highest incidence (24.6%); 312 Euro-American and 225 Hispanic students' incidence was intermediate.
