Basic skill requirements for selected Army occupational training courses

This study investigated the basic cognitive skills soldiers must possess before entering the Army, skills that are needed for successful completion of entry-level training. Judgments of 126 instructors from 25 military occupational specialties were obtained on 129 candidate skills, which resulted in the identification of 55 basic skills. Factor analysis of these 55 skill items resulted in 11 interpretable factors. Mean scores on the factors were compared across factors and across Army training schools. The results of the study suggest that, for all occupational specialties studied, skills related to the learning process are as crucial as traditional academic skills for successful training course completion. These results have important implications for training for the Army as well as for industry.     

Gender,culture, and geography: A comparison of seating arrangements in the United States and Taiwan

The present study describes and compares seating preferences among Taiwanese and American respondents. Using a questionnaire method, seating preferences were obtained for 75 male and 100 female college students from the United Slates, and for 29 male and 54 female teachers of English in Taiwan. Responses were obtained for all possible combinations of sex of interaction partner, location (task or social), and six interpersonal activities. Results were summarized in the form of proportions of respondents choosing each of four possible angles of interaction: corner, opposite, diagonal, and side seating. Comparisons were made using Chisquare tests for independence.In general, results showed that Taiwanese respondents, when compared to Americans, are more likely to prefer side seating and less likely to prefer corner seating. Culture, sex of respondents, and sex of interaction partner interact in influencing preferences. In the United States, seating preferences function to unite males with females and to separate same-sex partners, while the opposite is true in Taiwan. Results are interpreted in terms of implications for intercultural communication.     

MCL-1及其BH3螺旋结合自由能计算研究蛋白-蛋白相互作用原理(英文)

MCL-1蛋白是细胞增殖和分化的一个关键调控因子.使用MM-PBSA方法预测MCL-1蛋白与其野生型和碳氢化合物钉子修饰的BH3多肽形成的2个复合物的结合自由能.结果表明,碳氢化合物钉子对多肽与MCL-1的亲和力影响有限;并利用自由能分解(BFED)计算部分残基的能量贡献.疏水效应是稳定复合物结构的主要因素,它同时被额外的静电相互作用强化.该研究在原子水平上探究蛋白-蛋白相互作用机理,提供了新的癌症治疗候选药物.     

Mathematics: a female,male or gender‐neutral domain? A study of attitudes among students at secondary level

The aim of the current study is to investigate whether Swedish secondary school students perceive mathematics as a female, male or gender‐neutral domain. A sample of 1300 students in two age groups, 15‐ and 17‐ years, answered a questionnaire and about 50 students participated in interviews. The main part of the inquiry form consists of Who and mathematics, an attitude scale recently developed by other researchers. The results are analysed with respect to gender, school year and study programme. Gendered attitudes were found among considerable minorities. There is a marked tendency to view mathematics as a symbolically male domain: positive aspects are associated with boys and negative aspects perceived as more female. Older students hold more strongly gendered views than younger. Boys in the science programme have the strongest beliefs of mathematics as a male domain.     

二值图像的四边形区域压缩算法研究

从二值图像的区域特征出发，提出了基于四叉树的二值图像四边形区域压缩算法，该算法的思想是将二值图像用四叉树进行四分区域划分，在同一个区域中如果像素值相同则可用一个元素表示，否则继续划分，该算法的优点体现在如下两个方面：1．采用二进制移位的思想提高了MD码的生成效率。2．采用基于对数模型的方法进行区域像素压缩。该算法的内存开销小，运行速度高于其它相关方法。
