铝、镉、铜互作对不同耐铝大麦基因型糖及蛋白含量的影响

所有胁迫处理均导致耐性品种根系和叶片的蛋白质含量增加,三重复合胁迫时最高.低pH和Cu,Cd,Al复合胁迫使敏感基因型根系蛋白质含量增加而叶片蛋白质含量减少,其它胁迫结果恰好相反.Cu与Cd以及Cu,Cd,Al复合胁迫使耐性品种根系和叶片可溶性糖含量增加,单独Al胁迫使耐性品种根系和叶片可溶性糖含量减少,但对敏感基因型的影响因器官而异.Cu与Cd复合胁迫及单独Al胁迫均使耐性品种根系还原糖含量减少而使叶片还原糖含量增加,但对敏感基因型的影响存在差异;Cu,Cd,Al复合胁迫使敏感基因型根系、叶片和耐性品种根系还原糖含量增加,却使耐性品种叶片还原糖含量减少.各种胁迫处理均使耐性品种根系和叶片总糖含量下降,但敏感品种器官和处理间结果存在显著差异.

University Administrators as Information Tacticians: Understanding Transparency as Selective Concealment and Instrumental Disclosure

Despite its burgeoning popularity, the concept of administrative transparency has received little attention from interpretivist sociologists. Symbolic interactionism offers a theoretical and methodological agenda for understanding administrative transparency that departs from the more common quantitative‐ and factor‐based approaches. With an emphasis on educational administration, this article defines and examines how university administrators accomplish transparency in their everyday activities. Data from in‐depth semistructured interviews identify administrative transparency as a reflexive act of concealment and disclosure. These activities are further described by what are identified as silent budgetary bargaining and opportunistic budgeting.     

论网络教学的人文环境

网络教学和传统教学由于教学模式的差异形成了不同的人文环境,相对于传统教学,网络教学特有的"时空准分离状态"造成了当前网络教学缺少"人文关怀"这一不足。而人文环境在教学中将直接影响到学习者的情感,对激发学生的学习动机,促进学习者的认知和人格的健康发展都能够起到积极的作用。有别于传统教学丰富的情感交流,人文环境的欠缺已成为制约网络教学发展的一大"瓶颈"。要解决这一问题,可以通过设置问题和助学栏目、利用BBS和VR技术,以及组织讨论等加强师生之间、学生之间的交流,营造良好的人文氛围,从而激发和提升网络教学学习者的学习兴趣、自主性、创造性和合作性,推动网络教学的进一步发展。     

网络互动中人际信任概念辨析

因特网的虚拟性和匿名性等特征,使网络人际信任的内涵有别于现实社会。网络人际信任是交往双方对对方能够完成自己所托付之事的一种概括化期望,是心理预期和行为策略的统一。风险小、潜在威胁小是网络人际信任的基础;情感风险是网络人际信任的主要内容;文本符号是网络人际信任关系的中介。

Preschool Boys with Pervasive Hyperactivity: Early Peer Functioning and Mother–Child Relationship Influences

This study compared the peer functioning of a community sample of preschool boys with pervasive hyperactivity (N=33) and comparison boys (N=34), and examined the extent to which any differences in peer functioning between these groups could be explained by comorbid child conduct problems and parenting factors. The quality of boys’ peer relations was assessed on the basis of teacher and observer ratings of peer‐related behavior at preschool. The quality of parenting and boys’ behavior at home were assessed using the Parental Account of Children's Symptoms Interview, the Parenting Scale, and videotaped mother–son interactions. Boys with hyperactive behavior problems showed higher rates of aggressive, noncompliant, and nonsocial behaviors, and lower rates of prosocial behavior and peer acceptance than boys in the comparison group. These between‐group differences in social functioning remained significant following statistical control for the effects of conduct problems, highlighting the wide range of peer difficulties associated with preschool hyperactivity. Results of further analyses suggest that the quality of early mother–child interactions and the behavioral features of hyperactivity may make unique contributions to the 00development of peer relationship difficulties in preschool children with pervasive hyperactivity.

关于土族民间信仰及习惯法的人类学分析

土族习惯法的产生、发展和运作深受土族民间信仰的影响,习惯法中的大部分内容都是由民间信仰中的各种禁忌、仪式、巫术构成,而神灵观念和内心的信仰是土族习惯法最主要的来源,各种禁忌、巫术直接推动着土族习惯法的有效执行。同时,土族习惯法又维系着民间信仰的内在结构,强化了民间信仰的社会功能。     

情感能量的理性化分析--试论柯林斯的"互动仪式市场模型"

以经济分析的方法研究一切人类行为尤其是非经济领域的行为,在社会科学界一直备受关注且争论颇多。柯林斯以社会学的视角借鉴了理性选择理论的分析框架,但做了重大的修正。他构建了颇具社会学意味的互动仪式市场模型与理性行为目标,试图以此解决利他行为、情感行为等非经济行为与理性人假设的结合, 以及不同价值之间的理性选择等问题。
