培养基成份对大麦花粉植株高频率再生的影响

在一种基本培养基 FHG 上研究了培养基的多种成份对大麦花粉植株再生频率的影响。诱导培养基中不同的激素配比对愈伤组织诱导数影响很大,在145诱导培养基上,得到一个花药产生16.70块愈伤组织和5.5棵绿苗,分别是对照的2.4倍和3.8倍。在不同的分化培养基上,绿苗分化率以R63培养基为好;培养基中补加 MET 后,能明显的提高绿苗分化率及绿苗产量,最适宜的浓度为0.6mg/L,分别是对照的4.1倍和4.4倍。MET 对大麦花粉植株诱导生根及壮苗也有明显的作用。不同的氨基酸种类对绿苗分化率及绿苗产量作用不同,这种作用具有基因型效应。对 Igri 以730mg/L 的谷氨酰胺绿苗产量最高;谷氨酸次之。     

德国1848年革命初期法兰克福"工人协会"与国民议会资产阶级自由派的斗争

德国1848年革命初期法兰克福"工人协会"与国民议会资产阶级自由派的斗争是法兰克福工人协会为建立统一不可分的德意志共和国和维护无产阶级切身利益的斗争,是德国1848年革命不可缺少的组成部分。这一斗争后不久的1848年法兰克福九月起义是这次斗争的合乎逻辑的发展。     

An evaluation case: The implementation and evaluation of a problem-solving training program for adolescents

This study recounts the implementation and evaluation of a problem-solving skills training program for adolescents. Sixty-six students from the seventh, eighth, and ninth grades of a local junior high school were identified by guidance counselors as needing problem-solving training—48 male and 18 female students between the ages of 11 and 16. The hypothesis that students included in the training sessions would demonstrate better problem-solving skills, a more internal locus of control, and a higher level of self-esteem than control group students was tested via a pretest-posttest Control Group Design. The results of a stepwise discriminant analysis of the data supported the hypothesis. An analysis of grade level differences indicated that the program had less effect on the seventh-grade training group. Implications for program modification and the limitations of the evaluation findings are discussed.

七年制临床专业学生自我效能感与心理健康的相关研究

目的探讨七年制临床专业学生一般自我效能感、心理健康的特点以及相互关系,为高校大学生心理健康教育提供依据。方法采用一般自我效能感量表(GSES)、症状自评量表(SCL-90)对240名医学生进行测评。结果不同性别学生一般自我效能感、心理健康水平差异无显著性,医学生一般自我效能感与心理健康各因子存在显著负相关(P<0.001),结论一般自我效能感与心理健康各因素存在显著的相关关系。一般自我效能感是影响学生心理健康的重要变量。

“312“经络锻炼法对中老年高脂血症疗效和相关机理的研究

目的探讨“312”经络锻炼法对高脂血症(高脂蛋白血症)的疗效和相关作用机理。方法 30例高脂血症患者坚持“312”经络锻炼法(简称“312”),于“312”前及后1、3、6个月,定期追踪其症状、血压、血脂等指标的变化,观察比较, 分析总结。结果①血脂:30例高脂血症患者其血脂各项指标于“312”锻炼后3、 6mon与“312”前比较均有显著性差异,(P<0．01):②临床疗效:其症状、体征、血压等临床疗效亦相应地有明显好转。“312”3、6mon后显效率各分别为47％、60％, 减轻率43％、37％,无效率10％、3％。结论①“312”能有效地降血脂,长期坚持“312”对高脂血症具有显著疗效。②“312”具有简、便、廉、验的特点,无任何副作用,应大力普及推广,尤其在农村。     

Evaluations of the special supplemental program for Women,infants, and children's (WIC's) effectiveness

The U.S. General Accounting Office (GAO) analyzed the evaluations of the Special Supplemental Program for Women, Infants, and Children (WIC) to determine whether they support assertions that have been made about the program's positive effects for five outcomes. Insufficient evidence was found for making any general or conclusive judgments about WIC's effectiveness overall, but in a limited way, the information does indicate the likelihood that WIC has positive effects in some areas. GAO also assessed problems in the state of evaluation efforts. That the program evaluations do not reveal whether WIC is having the effect intended by the legislation underscores the need to design and implement better studies. Generally speaking, GAO believes that if the lessons learned from past efforts are heeded, it should be possible to produce information on the overall effectiveness of WIC.     

A Modified Knox Test of Space-Time Clustering

Tests of space-time clustering such as the Knox test are used by epidemiologists in the preliminary analysis of datasets where an infectious aetiology is suspected. The Knox test statistic is the number of cases close in both space and time to another case. The test statistic proposed here is the excess number of such cases over that expected under H₀ of no infection. It is argued that this modified test is more powerful than the Knox test, because the test statistic is not heavily tied as is the Knox test statistic. The use of the test is illustrated with examples.
