The relative effects of the frostig program, corrective reading instruction, and attention upon the reading skills of corrective readers with visual perceptual deficiencies

How effective are the Frostig training program and corrective reading instruction for improving the reading and visual-motor skills of pupils who possess deficiencies in both areas? Each of the three teachers worked each school day for sixteen weeks with the subjects of the two treatment groups plus a play placebo group. On the basis of the results of this study there is little, if any, support for the use of the Frostig program or corrective reading as treatments to improve the reading skills of children considered to possess a visual-motor problem. Due to the performances of the attention-placebo group, it is logical to hypothesize that improvements of the remedial groups are more a function of personal attention than the unique remedial powers of the two treatments. Consideration should be given to the optimal number of Frostig sessions as well as to the possibility of a ceiling effect of the Frostig program. Eight weeks of training would appear to be the maximum time before regression or improvement takes place.     

Certification patterns and requirements for school psychologists

A questionnaire was sent to 50 state superintendents of public instruction and to directors of education in five U.S. territories. Information was requested relevant to state certification for school psychologists, including minimal academic, teaching, and internship requirements. Fifty-five questionnaires were returned. Forty-four states and territories indicated certification standards which were subsequently discussed in detail. Trends noted were: more states requiring certification for school psychologists, higher academic requirements, increasing levels of certification, and a shift away from a mandatory teaching certificate for state certification as a school psychologist.     

The school psychologist in a non-school setting

School psychologists may be found in non-school settings which allow them to use training and experience gained in a school psychology doctoral program. This article briefly describes one such setting and emphasizes the need in multidisciplinary clinics for more psychologists with this training, since it enables them to make unique contributions to education, interdisciplinary communication, clinical diagnoses, and research. Children's clinics need a person who is knowledgeable in both education and psychology and who is trained to work effectively with other disciplines.     

Use of health-related online sites

This report offers recommendations to physicians who provide information or services through online sites. The recommendations maintain that physicians responsible for health-related information should ensure that it is accurate, timely, reliable, and scientifically sound. Also, advice to the online users with whom physicians do not have pre-existing relationships or the use of decision-support programs that generate personalized information directly transmitted to users should be consistent with general and specialty-specific standards. In particular, these standards address truthfulness, protection of privacy, informed consent, and disclosures including limitations inherent in the technology. Finally, physicians who establish or are involved in health-related online sites must minimize conflicts of interest and commercial biases and, if patient specific information is transmitted, they must provide high-level security protections, as well as privacy and confidentiality safeguards.     

汉字刺激质量与语义启动间的交互作用

本研究探讨汉字刺激质量与语义启动的相互作用,深入考察汉字识别的内在机制。实验采用真假字判断范式,实验1使用语义相关词对比率较高的实验材料,实验2使用语义相关词对比率较低的实验材料,结果发现：（1）无论语义相关词对比率高还是低,均存在语义启动效应和刺激质量效应,且汉字刺激质量与语义启动之间均存在交互作用;（2）轻度模糊刺激较重度模糊刺激受到的语义启动效应更大。结果表明,即使排除了额外反馈的作用,汉字刺激质量与语义启动之间仍存在交互作用,进一步支持交互激活模型。     

Explaining Differences in Subjective Well‐Being Across 33 Nations Using Multilevel Models: Universal Personality,Cultural Relativity,and National Income

This multinational study simultaneously tested three prominent hypotheses—universal disposition, cultural relativity, and livability—that explained differences in subjective well‐being across nations. We performed multilevel structural equation modeling to examine the hypothesized relationships at both individual and cultural levels in 33 nations. Participants were 6,753 university students (2,215 men; 4,403 women; 135 did not specify), and the average age of the entire sample was 20.97 years (SD = 2.39). Both individual‐ and cultural‐level analyses supported the universal disposition and cultural relativity hypotheses by revealing significant associations of subjective well‐being with Extraversion, Neuroticism, and independent self‐construal. In addition, interdependent self‐construal was positively related to life satisfaction at the individual level only, whereas aggregated negative affect was positively linked with aggregate levels of Extraversion and interdependent self‐construal at the cultural level only. Consistent with the livability hypothesis, gross national income (GNI) was related to aggregate levels of negative affect and life satisfaction. There was also a quadratic relationship between GNI and aggregated positive affect. Our findings reveal that universal disposition, cultural self‐construal, and national income can elucidate differences in subjective well‐being, but the multilevel analyses advance the literature by yielding new findings that cannot be identified in studies using individual‐level analyses alone.     

肿瘤疫苗治疗肿瘤的前景

肿瘤疫苗的发展已经历了一个多世纪,20世纪50年代,人们开始了自体肿瘤疫苗的研究.使肿瘤疫苗(主动性免疫治疗)成为继手术、放疗、化疗之后的肿瘤治疗方法.肿瘤疫苗作为主动特异性免疫治疗,在临床中起到越来越重要的作用,人们开始尝试利用多种方法制备肿瘤疫苗并利用其促进机体免疫应答,从整体细胞,分子水平调控机体对肿瘤的免疫.目前肿瘤疫苗的研制已取得很大进展,给人类战胜肿瘤提供很大希望.     

血压的生物节律与高血压的时间治疗学

人体血压的昼夜节律现象具有重要临床意义,高血压病更尤为如此。不同降压药物或不同时间用药对血压的昼夜节律产生不同的影响。高血压时间治疗学是根据疾病发生或发作的昼夜节律特征,通过调整投药时间及/或剂量、或应用特殊制剂,调整血液或组织中的药物浓度,从而增加疗效并减少或避免不良反应的发生。时间治疗学方法有助于以最小的医疗经济学及毒副反应代价获取最佳的治疗效果。
