Facebook fan page: the effect of perceived socialness in consumer–brand communication

Facebook has become an important platform for a brand–consumer relationship channel. The current study investigates the influence of perceived socialness and its effect on consumers’ attitude toward brands. Participants (N = 404) were recruited in a large southeast university. A 2 (socialness: high vs. low)?×?2 (feedback control: high vs. low)?×?2 (brand image: high vs. low) between-subject design was conducted. The results of this study identified three important findings. First, high (vs. low) socialness elicited higher perceived relationship commitment, brand trust, and more favorable brand attitude. Second, the effect of socialness on brand attitude was moderated by brand image (positive vs. negative). Third, the mediation analysis showed that the effect of socialness (high vs. low) on brand attitude was fully mediated by perceived relationship commitment and brand trust.     

Sketchy communication: An experiential exercise for learning about communication in business

To be an effective communicator, students need to learn how to select the appropriate means of communication and be aware of potential obstacles. The model of communication process can be an effective framework for students to understand many pitfalls of the communication process. The described activity enables students to experience communication at different levels of richness (e.g., face to face, instant messaging, email) and with varying levels of feedback and noise. After completing the activity, students will understand the importance of precise, rich messages, seeking and providing feedback, and the difficulties that can occur at every step in communication.     

Using a mobile application to test the impact of giving feedback onteam-level conflict

The authors explored using a mobile application called DevelapMe for 278 business undergraduates in 54 teams to give real-time peer-based feedback during a 5-week group project. Two online surveys, Time 1 (T1) and Time 2 (T2), were administered. Results included finding three promising, new give-feedback scales: positive rating with comments, negative rating with comments, and negative/neutral rating without comments. Relationship conflict and task conflict were the outcomes. Relationship conflict significantly increased from T1 to T2. Only positive rating with comments had a significant relationship to T2 relational conflict and task conflict. Research exposing students to real-time feedback apps will prepare them for future work in teams.     

一种基于方向标记的有限反馈量化方法

随着天线数目和反馈比特数的增加,大规模多输入多输出（Multiple-Input Multiple-Output,MIMO）信道向量量化的复杂度大幅增加。为此,提出了一种基于方向标记的有限反馈量化方法。该方法将码本中码字进行分组,每组选取一个向量作为方向标记向量,在进行量化时,信道向量首先与各组方向标记向量进行比较,将与信道向量最接近的方向标记向量所在组选为待选码本组;在待选码本组内进行下一步量化,最终选出与其最接近的量化向量为最优码字。复杂度分析与仿真结果表明,所提方法缩小了待选码字的数量从而降低了计算复杂度,是系统性能与计算复杂度的一种折中。     

英语写作中同伴反馈对学生注意的影响

统计结果表明,英语写作中同伴反馈对高、中、低水平组学习者的注意都有显著性的促进作用,且同伴反馈对于高、中、低水平组学习者注意的促进作用可以和教师反馈相媲美。本文以中国大学生为调查对象,调查在中国语境下英语写作中同伴反馈对不同英语水平的学生注意的影响。     

同伴互评与教师反馈结合写作教学模式初探

运用同伴互评与教师反馈相结合的写作教学评改模式,教师应对学生进行有针对性的互改技巧培训,同时教师应尽量给学生提供表扬性和鼓励性评语。教师反馈应侧重于对作文深层方面的修改,提高学生的整体写作水平。     

股指期货如何影响股市稳定性?——对全球主要市场的三角度实证检验

以全球多个市场作为实证检验对象,从股市波动率变化、系统风险变化以及股市正反馈交易行为影响三个角度,分析股指期货市场稳定作用的含义,即对股市波动的影响及其作用表现,较为全面地解读股指期货的市场稳定作用。研究发现:三个角度都支持股指期货的市场稳定作用;而抑制正反馈交易的作用最为基础、直接和显著,是股指期货市场稳定作用的更为恰当的判断标准。

360度绩效考评与中国企业文化

绩效考评是人力资源开发与管理中的一项重要任务,绩效考评方法的科学与否直接影响着企业的发展和竞争力。360度绩效考评方法因其特有的全方位、多角度,考评结果可接受性强,误差小等特征而备受西方理论界和企业界的推崇并且卓有成效。文章认为:由于东西方文化的差异,西方行之有效的方法在引入我国后,必然受到东方文化的冲击。我国企业界在借鉴这一方法时,要考虑到文化因素的影响,不能盲目照搬西方的运作模式。     

The Role of Information Feedback in the Management Group Decision-Making Process Applying System Dynamics Models

The research project addresses the influence of feedback information on the decision process supported by the application of system dynamics models. A user-friendly application was developed and used in the experiment with decision groups. The participants were 174 undergraduate management science students. They had the task of determining the optimum business strategy by maximizing the multiple criteria function under three experimental conditions: a ₁) an indivIDual decision process without the support of a system dynamics model, a ₂) an indivIDual decision process supported by a system dynamics model, and a ₃) a decision process supported by a system dynamics model and subject interaction via computer mediation. The hypotheses that the indivIDual decision process supported by a system dynamics model yields higher Criteria Function values than one without a system dynamics model, as well as the decision process supported by both a system dynamics model and subject interaction yields higher Criteria Function values than one supported by a system dynamics model alone were confirmed.
