电视娱乐节目的价值引导与文化鼓励功能——以湖南卫视《我是歌手》为样本进行言说

湖南卫视＂领SHOW2013＂的开篇之作《我是歌手》开播以来,叫好又叫座,原因在于其既富有观赏性,又兼具价值引导与文化鼓励的功能。主要体现在其迎合受众的心理需求,重在展现人性的善良美好;重新建构了关于成功的集体认同,消解了以往片面的成功观;致力打造偶像全面的人格魅力,树立了正确的偶像观;激活了集体无意识下的怀旧审美,直击受众心灵。这些对其他电视娱乐节目的借鉴意义在于,作为成功电视娱乐节目的共同标准,价值引导与文化鼓励的内涵可以理解为：能够消解和扭转当前社会的不良风气和思想趋向;能彰显真善美和展示人性的光辉;能够顺应受众需求及调试受众心理;能唤起民众内心深处的美好情感以及传递正能量。     

组合压气机中尾迹与势流同频/异频干涉的叠加特性

为揭示多级压气机中上下游叶轮对中间叶片叠加气动影响特性,阐述不同叠加干涉情况下下游叶轮进气角度变化,采用数值方法模拟了一级轴流和一级离心组成的组合压气机非定常流场。详细讨论了上游动叶尾迹和下游动叶势流对中间导流叶栅段气流非定常流动的异频和同频叠加干涉特性,依据计算结果,直观地展示了静叶通道中两种干涉间相互激励和抑制作用的位置和时间,与数学公式的推导结果相互印证。研究结果表明:当上下游动叶对中间静叶段异频干涉时,干涉的激励、抑制区域的轴向位置随时间发生变化;当上下游动叶对中间静叶干涉频率相同时,干涉的相互激励、抑制区域的轴向位置不随时间发生变化,但干涉的激励、抑制区域的轴向位置受时序位置影响。另外,上游动叶尾迹与下游离心叶轮势流的不同叠加情况,决定着下游离心叶轮进口相对气流角的大小及波动幅值。      

Communications Approaches to a Cleaner Environment

Abstract

Recent studies of ideologies of sustainable farmers and conventional farmers suggest that these two groups have differing beliefs, values, and attitudes on agriculture and rural life. Although awareness of these differing attitudes and values is an important step in moving toward educational programs and policies for a more sustainable agriculture, actual behavior may not be predictable from this knowledge. A mail survey of Iowa farmers with membership in Practical Farmers of Iowa, a sustainable agriculture organization, was used to examine the attitude—behavior relationship of these farmers and the role social influences play in this relationship. Attitude and social influence scales were developed, as well as a chemical input index that measures commitment to sustainable practices. The results indicate that, when controlling explanatory factors, the attitude—behavior relationship is moderate and the social influences examined do not facilitate this relationship. Implications for educational programs and policies of these findings are discussed.     

The development of a perceived masculinity scale

This essay posits that masculinity can be usefully understood from a communication perspective, and it specifically defines masculinity as a social and symbolic construct. In this view, the meanings and associations attributed to masculinity are a product of the enduring images and characteristics people have ascribed and assigned to men in groups over time. Based upon a survey of contemporary published research regarding masculinity, it is concluded that masculinity is now a multidimensional construct which attributes ten traits to people viewed as masculine which are examined in terms of: (1) physiological energy; (2) physical characteristics; (3) gender‐related sociocultural roles; (4) idealized gender; (5) gender preferences; (6) subjective gender‐identity; (7) gender‐related age identity; (8) gender‐related racial and national identities; (9) lust; and, (10) male eroticism. Specific questionnaires used to measure these dimensions are reviewed, and based on the responses of 562 subjects, the reliability and validity of one of these questionnaires is examined in detail. The essay concludes by recommending the use of the Perceived Masculinity Questionnaire 47, and it outlines some of the uses that can be made of a Perceived Masculinity Scale, especially some potential classroom uses.     

High school students’ scientific epistemological beliefs,motivation in learning science,and their relationships: A comparative study within the Chinese culture

This study explored the differences in high school students’ scientific epistemological beliefs (SEBs), motivation in learning science (MLS), and the different relationships between them in Taiwan and China. 310 Taiwanese and 302 Chinese high school students’ SEBs and MLS were assessed quantitatively. Taiwanese students generally were more prone to believe that scientific reality is invented, the development of scientific knowledge is culture-dependent, and scientific knowledge is always changing and its status is tentative than the Chinese students were. Yet, the Taiwanese students perceived higher test anxiety in science than the Chinese students did. Moreover, Chinese students who have a stronger belief that science knowledge is changing and tentative are more likely to perceive themselves as having higher test anxiety in science. The results suggest that the role of culture might have an impact on students’ SEBs and their MLS.     

谈新形势下高职教育观念

人的行为都是受观念支配的,不同的思想观念,会产生不同的行为结果。我国的高等职业教育发展的时间不长,人才培养目标和办学模式等还在不断的探索创新,但新的形势不仅为职业教育发展提供了良好的机遇,但同时又面临严峻的挑战。面对高等职业教育快速发展的形势,我们的教育思想、人才培养的方案、培养的目标、课程内容的设计、教学的方法及全方位素质教育等观念必须与时俱进。
