The Parasocial Contact Hypothesis

We propose a communication analogue to Allport's () Contact Hypothesis called the Parasocial Contact Hypothesis (PCH). If people process mass-mediated parasocial interaction in a manner similar to interpersonal interaction, then the socially beneficial functions of intergroup contact may result from parasocial contact. We describe and test the PCH with respect to majority group members' level of prejudice in three studies, two involving parasocial contact with gay men (Six Feet Under and Queer Eye for the Straight Guy) and one involving parasocial contact with comedian and male transvestite Eddie Izzard. In all three studies, parasocial contact was associated with lower levels of prejudice. Moreover, tests of the underlying mechanisms of PCH were generally supported, suggesting that parasocial contact facilitates positive parasocial responses and changes in beliefs about the attributes of minority group categories.     

Testing results analysis of contact materials’electrical contact performance

Because of the different ways in which contact materials work, the basic requirements for silver metal oxide contact materials are different. They are anti-welded and anti-erosion when closed, anti-erosion when broken, and arc easily moved and have smaller contact resistance. In this paper, La2O3 is used as a stable oxide in contact material to replace CdO. A new type of Ag/SnO2-La2O3-Bi2O3 contact material is first obtained through using powder metallurgical method. Then electrical contact material parameter tester is used to test the electrical contact performance of the contact material. Through experiments, the arcing voltage and current curves, arcing energy curves, fusion power curves while broken and contact resistance while closed were obtained. Analysis of the results showed that the addition of La2O3 makes the contact material have the following advantages: smaller electrical wear, smaller arc energy, smaller contact resistance and arc is more easily extinguished.

Contact hours in Dutch and Vietnamese higher education: a comparison

The number of contact hours, one of the important institutional context factors, was examined and compared between Dutch and Vietnamese higher education at institute and student levels in Psychology and Business and/or Economics specializations. The quantity of contact hours per credit point given by institutions was investigated in a number of Dutch and Vietnamese universities. Additionally, 104 students in Groningen, the Netherlands, and 140 students in Hanoi and Ho Chi Minh City, Vietnam, participated in the survey with a self-reported and self-assessed questionnaire on their study time allocation. Beside contact hours, other learning process related factors such as study activities, motivation, quality of instruction, and generic skills were examined to provide a better insight into these two systems. Results showed that Vietnamese students had significantly higher number of contact hours than Dutch students while their generic skills, motivation and time spent on independent study were a lot lower.     

口语教学中的口语技能的培养探

口语教学的基本任务就是通过训练培养学生的口语技能去发展学生的口语能力。如何注意学生的个体差异,为每个学生提供主动积极参与教学活动的保证：如何促使课堂中多种类型信息交流和及时反馈的产生,加强教师对学生、学生对教师、学生对学生多边多向的交互作用,真正达到情感交流、自然交往的目的。本文就此进行了初步探讨。     

从“无意识”到“血性意识”——论劳伦斯对弗洛伊德学说的继承与超越

D.H.劳伦斯与西格蒙德·弗洛伊德都致力于探索人类心灵的无意识领域,强调性欲在人本性中的作用.本文探讨劳伦斯与弗洛伊德学说的承继关系,指出劳伦斯的一些见解虽受惠于弗洛伊德,但劳伦斯是一位具有独创性的文学家,他的思想远比弗洛伊德的激进.     

Promoting the attitudes of nursing students towards refugees via interventions based on the contact hypothesis: A randomized controlled trial

A randomized controlled study was implemented on 90 nursing students in Turkey. The sample was divided into two groups: intervention and control group. The intervention group received education on refugee health and participated in a practical internship with refugees. Three scales were administered to the two groups at baseline (pre-test) and the end of intervention (post-test): "Xenophobia", "Attitude Towards Refugees" and "Intercultural Sensitivity". The three scale post-test scores of the intervention statistically significantly differed from control group and showed a statistically significant interaction between the groups and time in the two-way analysis of variance. The three scale post-test scores significantly differed from the pre-test scores in the intervention group, showing more relevant effects on xenophobia scale, two subscales of attitude towards refugees and intercultural sensitivity scale. The interventions based on the contact hypothesis improved nursing students' attitudes towards refugees.
