Responds to an L. J. Cronbach article (see record 1976-03506-001) and denies a rumor that the Nixon cabinet once discussed whether an article by A. R. Jensen on social class, race, and genetics (1969) could be used to justify reducing outlays to Blacks. Other topics include an Office of Economic Opportunity message expressing the belief that Head Start is experimental and that its effects at that point were not known.

引流为外科基本操作之一,也是外科手术中常用的治疗措施,对于外科医生来说较为熟悉.但关键问题是如何恰当而正确的使用引流术,应当引起我们的重视,否则不但起不到引流应有的作用,反而会加重或增加感染机会,产生合并症等严重的后果.外科引流是术中或术后处理常用的方法之一,在外科治疗中占有重要地位.引流种类较多,可分别置于切口,体腔,空腔器管,实质器官内,以引流血液,脓液,体腔液或胃肠道的液体和气体.正确的引流能促进术后康复,减少治疗时间,能使手术的应激反应减到最低程度.在临床上应遵循无菌,分类,固定,通畅,定位,定性,定量,定时,预防并发证的原则.  相似文献

The etiology of stuttering is controversial. The prevailing theories point to measurable neurophysical dysfunctions that disrupt the precise timing required to produce speech. Stuttering is a common disorder that usually resolves by adulthood. Almost 80 percent of children who stutter recover fluency by the age of 16 years. Mild stuttering is self-limited, but more severe stuttering requires speech therapy which is the mainstay of treatment. Delayed auditory feedback and computer-assisted training are currently used to help slow down speech and control other speech mechanisms. Pharmacologic therapy is seldom used, although haloperidol has been somewhat effective.  相似文献

Comments that N. A. Cummings's (see record 1986-22651-001) discussion on dismantling the health system should be required reading for all psychological health-care providers. Types of resistance are discussed that must be overcome by therapists learning and practicing short-term therapy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Early developments leading to the concept of a dislocation are discussed. The discoveries of 1934 are described. The subsequent evolution of various aspects of dislocation theory is outlined. This paper is based on a presentation made at the symposium “50th Anniversary of the Introduction of Dislocations” held at the fall meeting of the TMS-AIME in Detroit, Michigan in October 1984 under the TMS-AIME Mechanical Metallurgy and Physical Metallurgy Committees.  相似文献
