护理执行用药医嘱的伦理学思考

护理人员在医疗机构推行临床合理用药的过程中承担着十分重要的任务。加强护理人员的道德教育,提高护理人员的素质,提高药物使用业务知识水平,提高与药物临床使用相关的护理技能,真正体现医疗机构推行的"以人为本"的护理理念,为患者的健康、康复负责。     

技能和风格：理性思维的两种测量途径

本文通过总结前人关于理性思维的个体差异的研究, 介绍和区分了两种有关理性思维的测量途径, 并讨论了二者之间的内在关系。理性思维可以分成技能和风格两种形式。前者常用评价性的、情境测试方式进行评估, 后者常用描述性的、自陈量表方式进行测量。通过分析认知能力对这两种理性思维的影响, 本文提出一个认知能力与理性思维技能和思维风格关系的理论模型, 为后续在理性思维测量方法上的研究提供一种理论指导。     

Investigating speech motor practice and learning in people who stutter

In this exploratory study, we investigated whether or not people who stutter (PWS) show motor practice and learning changes similar to those of people who do not stutter (PNS). To this end, five PWS and five PNS repeated a set of non-words at two different rates (normal and fast) across three test sessions (T1, T2 on the same day and T3 on a separate day, at least 1 week apart). The results indicated that PWS and PNS may resemble each other on a number of performance variables (such as movement amplitude and duration), but they differ in terms of practice and learning on variables that relate to movement stability and strength of coordination patterns. These findings are interpreted in support of recent claims about speech motor skill limitations in PWS.

Educational objectives: The reader will be able to: (1) define oral articulatory changes associated with motor practice and learning and their measurement; (2) summarize findings from previous studies examining motor practice and learning in PWS; and (3) discuss hypotheses that could account for the present findings that suggest PWS and PNS differ in their speech motor learning abilities.     

The phenomenology of virtue

What is it like to be a good person? I examine and reject suggestions that this will involve having thoughts which have virtue or being a good person as part of their content, as well as suggestions that it might be the presence of feelings distinct from the virtuous person’s thoughts. Is there, then, anything after all to the phenomenology of virtue? I suggest that an answer is to be found in looking to Aristotle’s suggestion that virtuous activity is pleasant to the virtuous person. I try to do this, using the work of the contemporary social psychologist Mihalyi Csikszentmihalyi and his work on the ‘flow experience’. Crucial here is the point that I consider accounts of virtue which take it to have the structure of a practical expertise or skill. It is when we are most engaged in skilful complex activity that the activity is experienced as ‘unimpeded’, in Aristotle’s terms, or as ‘flow’. This experience does not, as might at first appear, preclude thoughtful involvement and reflection. Although we can say what in general the phenomenology of virtue is like, each of us only has some more or less dim idea of it from the extent to which we are virtuous—that is, for most of us, not very much.     

钦佩感：一种见贤思齐的积极情绪

钦佩感是对优秀他人或榜样的一种高度喜欢和尊敬, 是看到他人的优秀行为或品质时所产生的一种积极情绪, 其典型成分是欣赏和鼓舞。他人的优秀能力、美德、积极态度、自我提升动机、相似的价值观等因素影响钦佩感的产生。美德钦佩感会导致后叶催产素分泌, 和能力钦佩感分别激发不同但又相互重叠的脑区。钦佩感具有激励作用, 提高自我效能感和结果期望并影响其职业意向, 激发个体的亲社会动机与行为。拓展钦佩感的概念与成分、辨析与崇拜的相似与不同、开展钦佩感的应用研究以及跨文化或本土化研究等是该领域未来重要的研究方向。     

New Developments in Understanding Skilled Performance

ABSTRACT— Skilled performance, whether it involves rapid and accurate motor movements (such as playing a video game or using a scalpel in the operating room) or a high degree of domain knowledge (such as finding a small tumor in an X-ray or writing a journal article) typically involves learning and practice over an extended period of time. In light of recent theory and empirical research, I consider two enduring issues associated with skill acquisition: whether individuals become more alike in performance or more different over the course of skill acquisition, and what the determinants of individual differences in skilled performance are. Two broad classes of tasks are considered: tasks that involve speed and accuracy of motor movements and tasks that primarily involve domain knowledge. Issues of practice, ability, and other determinants of skilled performance such as gender and aging are discussed.     

THE EFFECTS OF DIFFERENTIAL REINFORCEMENT OF UNPROMPTED RESPONDING ON THE SKILL ACQUISITION OF CHILDREN WITH AUTISM

The recommendation to reserve the most potent reinforcers for unprompted responses during acquisition programming has little published empirical support for its purported benefits (e.g., rapid acquisition, decreased errors, and decreased prompt dependence). The purpose of the current investigation was to compare the delivery of high‐quality reinforcers exclusively following unprompted responses (differential reinforcement) with the delivery of high‐quality reinforcers following both prompted and unprompted responses (nondifferential reinforcement) on the skill acquisition of 2 children with autism. Results indicated that both were effective teaching procedures, although the differential reinforcement procedure was more reliable in producing skill acquisition. These preliminary findings suggest that the differential reinforcement of unprompted responses may be the most appropriate default approach to teaching children with autism.     

Manual dexterity in the gorilla: bimanual and digit role differentiation in a natural task

The manipulative actions of mountain gorillas Gorilla g. beringei were examined in the context of foraging on hard-to-process plant foods in the field, in particular those used in tackling thistle Carduus nyassanus. A repertoire of 72 functionally distinct manipulative actions was recorded. Many of these actions were used in several variants of grip, finger(s) and movement path, both by different individuals and by the same individual at different times. The repertoire appears somewhat greater than that observed in comparable studies of monkeys, but a far more striking difference is found in the use of differentiated actions in concert. Mountain gorillas routinely and frequently deal with problems that involve: (1) bimanual role differentiation, with the two hands taking different roles but synchronized in time and space, and (2) digit role differentiation, with independent control of parts of the same hand used for separate purposes at the same time. The independent control that allows these abilities, so crucial to human manual constructional ability, is apparently general in African great apes. Role differentiation, between and within the hand, is evidently a primitive characteristic in the human arsenal of skills. Accepted after revision: 6 April 2001 Electronic Publication     

THE EFFECTS OF FORM TRAINING ON FOUL‐SHOOTING PERFORMANCE IN MEMBERS OF A WOMEN'S COLLEGE BASKETBALL TEAM

The effects of instruction and feedback in proper form on foul‐shooting performance was evaluated in 3 players of a women's NCAA Division II college basketball team. Players showed an increase in percentage of shots made and in correct form compared to baseline shooting without instruction or feedback. All players reached criterion within seven training sessions. The results suggest that training proper form is an effective strategy for improving foul‐shooting performance.
