Prolog programming techniques

In this paper we introduce the concept of a Prolog programming technique. This concept is then distinguished both from that of an algorithm and that of a programming cliché. We give examples and show how a knowledge of them can be useful in both programming environments and in teaching programming skills. The extraction of the various techniques is outlined. Finally, we discuss the problem of representing techniques where we conclude that the most promising approach is the development of a suitable meta-language.     

单纤维对训练的适应

随着特殊的训练计划被教练员们采用以促进运动员的肌肉适应能力,肌肉训练也成为渐进式康复的重要组成部分,它能阻止与丧失运动能力、老化、疾病或微重力相关的萎缩效应。为了优化不同类型的干扰措施,需要更好地理解运动训练产生的反应,以及识别决定肌肉功能的各种机制。虽然整体肌肉活动在某种程度上是通过适应运动神经元爆发、运动单元补充模式或者肌肉量来进行的,本研究着重探讨肌肉纤维类型的表达以及训练后收缩肌的功能性适应能力。单一无皮纤维被证明是常用的实验模型,用于研究与肌浆球蛋白重链对碘氧基苯甲醚相关的试管内收缩特性。人体纤维主要的功能和生化特性在过去二十年中已经被详细研究了,但近来,无皮纤维模式正被用于研究不同类型的诱发训练后单纤维的功能适应性。本文的目的是概述收缩肌对于特定运动训练计划的反应,以及帮助形成适用于运动科学和康复的训练计划。     

Associations Between Child Disabilities and Caregiver Discipline and Violence in Low‐ and Middle‐Income Countries

Using nationally representative samples of 45,964 two‐ to nine‐year‐old children and their primary caregivers in 17 developing countries, this study examined the relations between children's cognitive, language, sensory, and motor disabilities and caregivers' use of discipline and violence. Primary caregivers reported on their child's disabilities and whether they or anyone in their household had used nonviolent discipline, psychological aggression, and physical violence toward the target child and believed that using corporal punishment is necessary. Logistic regression analyses supported the hypothesis that children with disabilities are treated more harshly than children without disabilities. The findings suggest that policies and interventions are needed to work toward the United Nations' goals of ensuring that children with disabilities are protected from abuse and violence.     

Mothers' parenting cognitions in cultures of origin, acculturating cultures, and cultures of destination

Japanese and South American immigrant mothers' parenting cognitions (attributions and self-perceptions) were compared with mothers from their country of origin (Japan and Argentina, respectively) and European American mothers in the United States. Participants were 231 mothers of 20-month-old children. Generally, South American immigrant mothers' parenting cognitions more closely resembled those of mothers in the United States, whereas Japanese immigrant mothers' cognitions tended to be similar to those of Japanese mothers or intermediate between Japanese and U.S. mothers. This study provides insight into the nature of parenting cognitions generally and those of immigrant mothers specifically and therefore the parenting climate in which immigrant children are reared.
