The Political Consequences of Ambivalence: The Case of Democratic Reform in Hong Kong

Recent research has shown that attitudinal ambivalence has importantimplications on political attitudes and behavior. The conceptholds one of the keys to understanding complicated and seeminglycontradictory opinions of the public. This article examinesambivalence in public opinion regarding democratic reform inHong Kong. Analysis of a representative survey (N = 600) showsthat common citizens indeed have a significant degree of ambivalencetoward the government's political reform bill proposed in 2005.Regarding consequences, objective ambivalence is shown to havegreater predictive power than subjective ambivalence. The formerrelates negatively to attitude extremity and weakens the attitude–behaviorlinkage. However, contrary to the usual finding in the literature,objective ambivalence also relates positively to protest participationintention. The theoretical and social implications of the findingsare discussed. Received for publication June 29, 2007. Accepted for publication October 8, 2008.

对高校思想政治理论课教学创新的思考——以“思想道德修养与法律基础”课为例

作为思想政治理论课新课程改革中第一门为大学生开设的课程,如何在教学理念、教学内容和教学方法上有所创新,不仅对学生学习、教师讲授这门课有指导意义,更重要的是对加强大学生思想政治教育会起到积极的推动作用。本文拟从新课程教学理念、教学内容、教学方法的创新等几方面进行探讨,以期能对增强这门课的教学针对性、实效性和吸引力,更好地完成教学任务、实现教学目标提供借鉴。     

认知省力:习语义产生的原动力

实现认知省力是习语义产生的根本动因。从人类的认知模式出发,对习语义形成过程的历时研究表明,习语义形成的过程主要有三种:隐喻、转喻和隐喻+转喻。这三种过程都受到认知省力原则的制约:人们通过熟悉的事物来认知陌生的事物,通过认知域中凸显的范畴来代替其他范畴,以此减少认知过程的时间、任务和难度,节省认知成本,达到认知省力的目的。     

Possible factors influencing Asian students' degree of participation in peer-facilitated online discussion forums: a case study

This study investigated possible factors that might influence the degree of student participation in asynchronous online discussion forums. Degree of participation refers to the number of messages posted by the students. Data were collected from 41 forums, students' reflection logs, and students' interviews. Of these 41 forums, the top third forums (n = 14) in terms of the highest frequency of participant postings were identified. Fourteen less frequent forums were randomly chosen from the remaining forums. We also assessed the quality of the discussions found in both the more frequent and less frequent groups by examining the levels of knowledge construction exhibited in the online postings. We found that that the quality of contributions in the more frequent group was greater than those found in the less frequent group in terms of higher knowledge construction levels. Quantitative analyses showed that the duration of the discussion could not account for the difference between the two groups. Instead, the more and less frequent forums differed in terms of group size, as well as the frequency of two habits of mind displayed by the student facilitators: (a) is aware of own thinking, and (b) is accurate and seeks accuracy. Qualitative analyses of the reflection logs and interviews suggested several other important factors that could also influence students' decision to participate: (a) familiarity with the facilitator, (b) mutual obligation to help each other, (c) knowledge about the topic, and (d) availability of time. Implications of the findings and suggestions for future research are provided.

Inducing self-rotation of cells with natural and artificial melanin in a linearly polarized alternating current electric field

The phenomenon of self-rotation observed in naturally and artificially pigmented cells under an applied linearly polarized alternating current (non-rotating) electrical field has been investigated. The repeatable and controllable rotation speeds of the cells were quantified and their dependence on dielectrophoretic parameters such as frequency, voltage, and waveform was studied. Moreover, the rotation behavior of the pigmented cells with different melanin content was compared to quantify the correlation between self-rotation and the presence of melanin. Most importantly, macrophages, which did not originally rotate in the applied non-rotating electric field, began to exhibit self-rotation that was very similar to that of the pigmented cells, after ingesting foreign particles (e.g., synthetic melanin or latex beads). We envision the discovery presented in this paper will enable the development of a rapid, non-intrusive, and automated process to obtain the electrical conductivities and permittivities of cellular membrane and cytoplasm in the near future.

从圈羊到放羊：体育专业研究生创新能力培养的范式转向

传统体育专业研究生的培养模式以＂圈羊式＂为其主要特点,外在的培养目标、规范化的课程体系、以控制为导向的教学方法和单一的评价模式是横亘在研究生创新道路上的层层藩篱。而实现从＂圈羊式＂培养模式向＂放羊式＂培养范式的转向,坚持以自组织为核心的、以创新能力的建构生成、课程体系的多元化理解、研究性学习方法和多元尺度评价为特点的新培养范式,则是推倒藩篱,引导研究生创新性不断生成的重要途径。
