The Suasory Force of Sticky Messages: An Application to the Application of Sunscreen

Stickiness refers to the set of persuasive message properties: simple, unexpected, concrete, credible, emotional, and stories (SUCCES). Heath and Heath (2007) argue that a sticky message is expected to be more memorable and hence more persuasive than a non-sticky message. A 2 (sticky v. non-sticky message) x 3 (pretest v. posttest v. delayed test) longitudinal experiment is employed to examine the persuasiveness of sticky messages on applying sunscreen. Results of a mixed model analysis of variance show that the sticky message produces attitudes and behaviors more favorable to the message recommendation than the non-sticky message. Specifically, a time × message induction non-additive effect was found, which sustained only in the sticky message condition across time. Despite this interesting effect, its explanation remains elusive.     

Examining the “Blanket of Protection” Conferred by Inoculation: The Effects of Inoculation Messages on the Cross-protection of Related Attitudes

Although the effectiveness of inoculation as a strategy for promoting resistance to attitude change is fairly well established, the potential of inoculation messages to offer cross-protection for related, but untreated, attitudes warrants additional attention from scholars. The reported study tested the “blanket of protection” conferred by inoculation. Participants (N = 118) were randomly assigned to read an inoculation message addressing a target topic and subsequently had their attitudes toward three related, but untreated, topics attacked. The results offer some evidence that inoculation messages can confer cross-protection for related attitudes. Participants in the inoculation condition reported greater perceptions of threat, greater counterarguing, and less attitude change in response to attacks than participants in the control condition for two of the three untreated topics. Counterarguing in response to attacks on untreated attitudes appears to be primarily responsible for cross-protection.     

The Combined Effects of Instructor Communicative Behaviors,Instructor Credibility,and Student Personality Traits on Incivility in the College Classroom

This study investigated the combined role of instructor communication variables (nonverbal immediacy and self-disclosure), instructor credibility (competence, caring, and trustworthiness), and student personality traits (extraversion, neuroticism, agreeableness, conscientiousness, and openness) in predicting students’ uncivil behaviors in class. A total of 406 students completed online questionnaires regarding the instructor of the class they attended prior to the one in which the study was administered. Personality and instructor behavior variables contributed approximately equally to explaining variance in student incivility. Students’ conscientiousness and agreeableness had direct negative relationships with incivility, whereas instructors’ amount and negativity of self-disclosure had direct positive relationships with incivility.     

SIP协议及其在网络中的应用

随着下一代互联网技术的不断发展,人们将不仅仅满足于将现有的PSTN(公共电话网)业务移植到IP网,而是需要电信运营商提供一个优秀的体系架构,将话音业务、视频业务、新兴的互联网业务整合到一个统一的框架中.SIP协议就是其中的关键纽带.     

基于消息的单片机编程方法

在单片机MCS-51的开发运用中，通常要使用各种中断。如中断服务程序执行时间过长，当有另外的中断发生时，单片机就不能及时地进行处理，特别是对MCS-51这样的只有两级中断优先级的单片机更是这样。借鉴Windows编程的原理，在单片机编程中引入消息的概念，将中断产生的标志作为消息，而数据处理则放在消息循环中进行，这样一方面减少了中断服务程序的长度，提高了响应中断的速度；另一方面又不影响数据的处理。

华语电影的英文字幕翻译——以电影《风声》为例

电影字幕翻译是一个新兴的翻译领域。从影片《风声》的英文字幕翻译来看,要准确还原影视对白或者独白原意,译者进行字幕翻译时,不仅要考虑到语言转换问题,还要考虑到影视字幕翻译自身的特点及东西方语言文化差异所造成的各种因素的制约。作为文化交流的中介,电影字幕的翻译应以观众为中心,根据实际情况采用不同翻译策略对影片中的文化信息做出灵活处理,使字幕翻译真正发挥文化传播的中介作用。     

Teacher e-mail message strategies and students' willingness to communicate online

In light of the prevalent use of e-mail between teachers and students, researchers have highlighted the need to assess its uses and effects. Relying on the research and thinking of teacher immediacy and extra-class communication, we developed a scale that measures those e-mail message strategies that influence students' willingness to communicate online with their teachers. Next, we isolated those reasons that students use e-mail to interact with their teachers: (1) to clarify course material and procedures, (2) as a means of efficient communication, and (3) for personal/social reasons. Finally, we examined student characteristics such as gender and ethnicity, and history of e-mail use that may (or may not) influence their attitudes toward e-mail exchanges with teachers.     

报文摘要加密技术在网络化考试中的应用

通过采用网络安全技术中经常使用的“报文摘要”算法．将考生的试卷内容和考生的考号进行摘要计算，然后生成一个固定长度的摘要．而考生试卷中的任何一个字节变化都会影响到该摘要，从而保证考卷的数据完整性。因此．当答卷被修改，或者考生对其答案是否被修改提出质疑时。系统会提供明确的证据。
