Faculty experience of rudeness in Scottish higher education: dealing with rudeness from students and colleagues.

This paper investigated rudeness experienced by academic staff from students, co-workers and senior staff members. The focus of much of the rudeness literature in an educational setting has been on the student experience of rudeness, predominantly in the classroom. The aim of the current study was to focus on the experience of academic staff rather than students, and to broaden consideration of rudeness beyond the classroom, to include e-mail. Using a mixed-methods questionnaire, with both closed and open questions, rudeness perception, impact and response was examined across a sample of 122 academic staff from Scottish Higher Education institutions. The study examined relationships between personality, stress, job satisfaction, level of rudeness and the impact of rudeness on staff. The qualitative segment explored responses to rude e-mails across three sources; student, colleague and senior colleague. The results indicated that academic staff reported similar levels of rudeness from students, co-workers and senior colleagues. Faculty who reported high levels of neuroticism were more likely to report a negative impact of rudeness. Academic staff also reported that their response to rudeness could differ according to the instigator: a greater proportion of staff reported that they would be likely to reprimand a student, in comparison to a colleague, for rudeness. Staff were more likely to seek an informal resolution to rudeness with a co-worker, rather than a student. This paper highlights the potential importance of individual characteristics in assessing the impact of rudeness on faculty and indicates that rudeness may come from several sources in academia.

运动员竞赛焦虑状态的分析

以参加第六届全国农运会田径项目的150名运动员作为研究对象,采用＂运动竞赛状态焦虑量表＂（简称CSAI-2问卷）为测试工具进行调查.结果表明：（1）不同性别的运动员竞赛焦虑状态各维度上不存在显著差异,但女运动员竞赛焦虑状态各因素得分略高于男运动员;（2）不同运动年限的运动员竞赛焦虑状态各维度上存在显著差异,运动年限越长竞赛焦虑状态各因素得分越高;（3）不同专项的运动员竞赛焦虑状态各维度不存在显著差异.     

再论大学的精神和职责

在人类文明发展的历史进程中,大学,特别是现代意义上的大学,作为社会的一个独特的文化教育机构,它的存在对于人类社会经济、文化的发展和社会的全面进步都起到了重大的推动作用,以至一所大学兴办的好坏成为一个国家和民族兴衰的缩影。而作为任何一所真正意义上的大学,都应该具备它应有的精神和职责。这就是:独立自由的灵魂、追求真理的品格、兼容并包的胸襟以及培养健全人格和合格公民的职责。     

一类三阶n点边值问题的正解的存在性

令ai≥0,i=1,…,m-3且am-2>0.再令ξi满足0<ξ1<ξ2<…<ξm-2<1且∑m-2i=1aiξi<1.我们研究下面边值问题正解的存在性u?(t)+a(t)f(t)=0,t∈(0,1),u(0)=u′(0)=0,u′(1)=∑m-2i=1aiu′(ξi)其中a(t)∈C([0,1],[0,∞]),f(t)∈C([0,1],[0,∞]).通过锥上的不动点定理证明了在f满足超线性或次线性条件下,上述问题至少存在一个正解.     

Vagueness in Teachers' Spoken Language

Politeness symbolizes human civilization,and is one of conduct codes of human beings.As a social activity,language use is subject to this code as well.Pragmatic vagueness is a common phenomenon in spoken discourse.Furthermore,it is an important strategy widely used in teachers’ spoken language.Based on the politeness principle,this thesis explores the pragmatic vagueness by analyzing teachers’ spoken discourse.Employing pragmatic vagueness in teacher’s spoken language can smooth the relationship between teachers and students,and help teachers gain foremost effect on the education to their students.     

花粉管通道法转基因对小麦主要农艺性状的影响

采用花粉管通道法介导外源耐盐基因SeNHX1导入4个小麦品种（品系）BN-64、YM-34、BM-1和AK-58中,并对转基因D0代的主要农艺性状进行了统计分析.结果表明,与对照相比,转基因D0代植株的种子（D1代）千粒重、株高、穗长、旗叶面积均有所提高;D0代植株与对照组相比,株高差异均达到显著水平,甚至极显著水平;穗长除BM-1差异不显著外,其余受体均达显著水平.叶面积差异均达到显著水平;叶长除YM-34外,其余受体差异均达到极显著水平.叶宽与受体相比均无明显差异.     

陆地棉F_2代单株选择的主成分分析

以抗虫棉品种和非抗虫棉杂交,在选择的条件下对F2代单株性状采用主成分分析的方法,就综合农艺性状对产量性状的影响进行了研究.结果表明：前5个主成分因子累积方差贡献率达74.95%,基本反映遗传信息.各主成分分析结果依次为：结铃性因子、形态因子、铃重因子、衣分因子、营养生长因子.依据主成分评价,较为理想的杂交F2代抗虫棉单株应是第1主成分较大,第2主成分适中的品种,即以果节数、果枝数和结铃数多,果枝夹角、株高和铃重适中的类型.通过5个主成分的总得分,构建出新的一个F2代单株选择指数,可以此作为F2代单株选择的依据.     

浅谈快乐体育与大学生个性发展

在大学学习中,作为一门以身体锻炼为主要手段,本体感受为主要形式的课程,体育课不仅增强了学生的体质,而且还在很大程度上改善了大学生心理健康以及面对社会、认识社会、适应社会的能力.因此,大学体育的教学形式,也就间接地影响着学生的个性发展.从快乐体育与大学生个性发展的关系等几个方面进行思考探索,为高校体育教学提供参考.     

消费主义与高校课程的文化际遇

消费主义进入高校,对高校课程的影响是全面而深远的。消费主义把课程仅仅作为一个消费的对象,课程被＂物化＂了,学生对课程的参与度降低,而且课程扁平化,师生关系异化。其积极影响有：课程效率提升与产业发展的距离拉近;消极影响有：课程中易出现短期行为,学生对课程体验的消解,以及＂单面人＂的出现和课程批判功能的消失。
