Self-Optimization of Walking in Nondisabled Children and Children With Spastic Hemiplegic Cerebral Palsy

Children voluntarily adopt a frequency and movement pattern for walking. The force-driven harmonic oscillator (FDHO) model was used in this study for accurate prediction of the preferred walking frequency of nondisabled children and children with spastic hemiplegic cerebral palsy. Four potential optimality criteria with which the preferred walking pattern was forced to comply were examined: minimization of physiological costs, maximization of mechanical energy conservation, minimization of asymmetry in lower limb movements and minimization of variability of interlimb and intralimb coordination. Age and gender-matched nondisabled children (n = 6) and children with spastic hemiplegic cerebral palsy (n = 6) were tested under six frequency conditions of walking at a constant speed on a treadmill. For the nondisabled children, the results indicated that their preferred walking frequency could be accurately predicted by the FDHO model. They freely adopted a walking pattern that minimized physiological costs, asymmetry, and variability of inter- and intralimb coordination. For the children with spastic hemiplegic cerebral palsy, the prediction of preferred overground walking frequency required that the FDHO model be modified to account for muscle mass and leg length discrepancies between limbs and increased stiffness. Most of the children achieved the same optimality goals as the nondisabled when walking at the preferred frequency. However, the children were found to use different mechanisms to attain these goals: for example, a steeper increase observed in physiological cost at higher frequencies; a lowered center of gravity of the body, which allowed for angular symmetry; and greater variability of between-joint coordination in the nonaffected limb and less variability in the affected limb.     

对人的尊严的挑战——试论P.辛格的优先权——实利主义

一个社会对其成员重视和承认的程度,首先表现为这个社会如何对待其成员中的弱者和受歧视的人。而在每个社会遭受歧视的人中,无疑也包括那些由于先天或后天的缘故患有精神上或肉体上的疾病而需要特别照顾的人。1989年以来,首先是这一社会群体的代言人,对他们的遭遇提出了强烈的抗议。而他们的抗议,又引发了德国舆论界对澳大利亚哲学家彼得·辛格的关注。特别是辛格关于可以对残疾人(既包括先天不足的婴儿,也包括老年人)施行强制性安乐死的论述,点燃了论战的烽火,更激起了一部分人的强烈抗议。残疾人的代盲人指出,辛格的“实用伦理学”不仅是对“残疾人”,而且从根本上讲是对人的错误认识。

The development of the Telic Dominance Scale

The development of a 42-item measure of a number of personality features derived from the theory of psychological reversals is reported. These personality features are (a) the extent to which a person is serious-minded, (b) the extent to which a person plans ahead and organizes himself in the pursuit of goals, and (c) the extent to which a person seeks to avoid arousal. These features together are seen to constitute a personality trait which is described as telic dominance. Data concerning the test-retest reliability, criterion-related and construct validity of the Telic Dominance Scale are presented, together with the scale and scoring key.     

法兰克福哲学-社会学学派基本思想的历史发展

在六十年代,资本主义用以攻击马克思列宁主义的新手法,特别清楚地表现在所谓“新左派”运动这种独特的左倾机会主义思想体系中。这种运动在1968年法国五一六月事件中表现得最为明显。在此之前不久,它也表现在六十年代左翼学生运动中,这个运动开始于美国、后来波及西欧许多资本主义国家,还传播到日本。对六十年代思想斗争所作的分析令人信服地证明,这种左倾机会主义的主要思想根源之一,就是所     

哲学的实践

哲学的功用问题,一经深究,便显得非常困难了。它包括许许多多重要而详尽的课题,需要从意识形态、方法论和历史上去作具体的阐述。“功用”(function)这个词,源于拉丁文“functio”,主要是指活动、作业、任务和位置的意思。因此,它包含很广泛的一类问题,在这篇文章中,只讨论社会意识那些最普遍的形式。正因为如此,我现在至多只能提出我自己     

关于制定唯物辩证法

在当前,世界观科学,尤其是我们世界观的核心——马克思列宁主义哲学的作用正在急剧地增长。马克思列宁主义哲学是工具,党借助于它影响我们的思想意识、引导我们沿着建设共产主义社会的道路前进,引导我们和敌对思潮进行斗争。在马克思列宁主义哲学中辩证唯物主义是主要的,这是列宁多次强调过的。同时,列宁也指出,辩证唯物主义和历史唯物主义是不可分割的。因为历史唯物主义是哲学唯物主义的继续,是哲学唯物主义在社会领域的彻底运用。列宁在辩证法是马克思列宁主义的灵魂这一著名原理中表述了这个思想。我们     

鲍波尔其人及其哲学

鲍波尔(Koal Popper)系奥地利自然科学和社会科学哲学家。1902年出生于维也纳,在那里,他研读数学、物理和哲学。尽管他不是逻辑实证主义维也纳学派的成员,而且在许多地方同他们还有着严重的分歧,但是他的哲学志趣却和该学派的主张还是颇为投合的。他同它的一些成员也有着密切的交往,对卡尔纳普的影响尤其明显。他的第一部成名著作《研究的逻辑》出版于1935年,当时就是列为维也纳学派的科学世界观丛书而问世的。1937年,鲍波尔赴新西兰坎特堡大学执教;1945年去伦敦大学伦敦经济学院工作。自1949年他一直是该学院的逻辑学和科学方法论教授。1964年封为爵士。他
