Some Correlates of Emotional Well-Being Among New England College Students

Abstract

In a questionnaire survey of New England college students, a large number of undergraduate men and women reported problems related to their personal, social, or academic adjustment. Given a list of 22 items described as “common concerns or feelings experienced by college students,” respondents were asked to rate the extent to which each item had been a problem for them in the past year. Most students (86%) reported having very much or somewhat of a problem with one or more items on the list. Pressure to do well in school, problems with weight control, anxiety, poor concentration and depression were among the most commonly reported concerns. The prevalence of these self-reported concerns and problems was found to be significantly associated with the respondents' sex, their perceptions of their health status, and academic standing.     

关于加快图们江地区能源项目合作的思考

图们江下游地区比邻俄罗斯和朝鲜,在东北亚地区合作中具有重要的战略地位。随着图们江区域经济政治环境的改善和地区合作开发步伐的加快,以俄罗斯远东地区石油管道建设为契机,引进石油资源,建立能源加工、供应基地,建设千万吨炼化项目,对保障我国能源供应安全,促进东北亚区域合作与发展具有重要的战略意义。     

高校计算机基础教学的改革与探索

随着计算机应用技术的迅速发展，大学计算机基础教学出现了一些问题。提出了针对存在的问题进行课程教学改革的思路，认为应以教师为主体，学生为主导，对计算机教学引导方面进行分析研究、探索教学方法，努力提高教学质量，培养出适应社会需要的计算机应用型人才。     

The Effects of a Computer Network on Pediatric Pain and Anxiety

SUMMARY

The objective of this study was to test the impact of an enhanced version of STARBRIGHT World (SBW2)-a private computer network for hospitalized children. The impact of SBW2 was assessed with a series of 44 replicated single system designs. Utilizing an ecological momentary assessment approach, self-reports were obtained regarding children's perceptions of their pain intensity, pain aversive-ness and anxiety. The results from the single system designs were aggregated using meta-analysis. Children experienced significantly less pain intensity, pain aversiveness, and anxiety in the SBW2 condition. These findings provide evidence regarding the effectiveness of SBW2 and demonstrate the utility of employing meta-analysis with single system designs.

冲旋钻头破岩机理仿真研究

介绍了冲旋钻井中冲旋钻头与岩石互作用有限元模型的建立过程，并对冲旋钻头在冲击旋转和单纯冲击载荷作用下的破岩过程进行了计算机仿真研究，描述了冲旋钻头破岩过程，求出了相应的钻头破碎岩石的深度、体积时程关系对比曲线，揭示了冲旋钻头的破岩机理——钻头在冲旋作用下破碎岩石的过程可分为4个阶段、钻头破碎岩石深度主要取决于冲击作用而与旋转作用关系不大、破岩体积在冲旋作用下比单纯冲击载荷作用下要大一倍左右，为冲旋钻头在石油工业中的进一步推广应用提供了理论依据。     

Computer Diffusion and Worker Empowerment

Abstract

Much anecdotal material describes various human impacts of computer adoption within the social work profession, however, there is scant research which confirms or challenges these assumptions. This article describes a study which investigates the diffusion of computers into the social work profession in terms of empowerment as an individual outcome for workers. A questionnaire returned by 520 social workers provided data on organizational computer diffusion, organizational centralization, and the Social Worker Empowerment Scale. Workers in organizations where computer diffusion was more advanced, and those in more decentralized decisionmaking environments were found to be more empowered.     

计算机文化基础实验课网络教学的实证研究

针对传统的计算机文化基础实验教学存在着教学模式单一,师生、生生之间的互动交流少,学生的积极性不高,课时量不足等问题,在分析计算机文化基础实验教学研究现状的基础上,研究利用天空教室来开展计算机文化基础实验课网络教学,开展了教学实验。研究结果表明,利用网络平台开展计算机文化基础实验课教学,具有传统教学无法比拟的优势,利用此网络平台开展计算机文化基础实验教学,有助于提高大学生的计算机操作技能和信息素养。     

高校多媒体组合教学与教学质量的提高

多媒体组合教学的应用,增加了教学内容的直观性,便于学生理解问题,降低了知识难度.提出教师要不断的学习更新知识结构,结合教学内容引进或研制教学课件.学校要积极为研制多媒体课件的教师提供便利条件,提高多媒体组合教学的质量.
