Is there more to email negotiation than email? The role of email affinity

Email has profoundly influenced the way we communicate personally and professionally and, for many, email negotiations have become a common, every day experience. While many studies have investigated email negotiations by relying on and discussing the characteristics of the medium, this paper focuses on the user’s attitude toward the medium and its respective influence on email negotiation. Specifically, we investigate which dimensions make up negotiators’ attitude toward email, i.e. their email affinity, and how these attitudes, in turn, influence the negotiation outcomes. In our scale development, three facets of email affinity are theoretically considered, empirically explored and validated: email preference, email comfort and email clarity. Our negotiation study contains a quasi-experimental email negotiation exercise where subjects were paired according to their email affinity. Email comfort emerged as a significant predictor of individual profit, joint gain, and different dimensions of subjective value. Theoretical implications and further research are discussed.     

有限套利与股价同步性的实证研究

通过构建代理变量衡量市场有限套利程度,验证了我国证券市场有限套利对股价同步性波动的影响。研究发现,现金股利作为控股股东利益输送的手段,增加了套利者的持有成本,现金股利与股价同步性显著正相关;交易成本越高,套利局限越严重,股价同步性波动越强;投资者成熟度越高,套利交易越活跃,股价同步性现象变弱。这说明,市场对套利的限制程度越高,股价同步性波动越强。     

基于电视负荷监测的频率逆调节策略在广东电网中的应用

电力系统的负荷特性会随着全国性的集体行动或重大事件表现出极强的同时性,给调度的频率调控和系统安全造成了极大影响。在总结历次特殊负荷日频率调控经验的基础上,提出了应对系统负荷同时性变化的频率逆调节策略,并在国庆日首次应用了基于电视直播画面监测的负荷预测及频率逆调节方法,成功的进行了频率控制。该策略为调度员预先评估频率调控点、预测电视节目对频率影响时域等方面提供了有效的手段,提高了频率调控能力。通过实际测试数据,进一步对比分析了电视负荷与电网频率波动的关系,估算了广东省总体电视负荷容量与波动幅度,对今后类似负荷日的频率调控策略有重要的指导意义。

Emotions over time: Synchronicity and development of subjective, physiological, and facial affective reactions to music.

Most people are able to identify basic emotions expressed in music and experience affective reactions to music. But does music generally induce emotion? Does it elicit subjective feelings, physiological arousal, and motor reactions reliably in different individuals? In this interdisciplinary study, measurement of skin conductance, facial muscle activity, and self-monitoring were synchronized with musical stimuli. A group of 38 participants listened to classical, rock, and pop music and reported their feelings in a two-dimensional emotion space during listening. The first entrance of a solo voice or choir and the beginning of new sections were found to elicit interindividual changes in subjective feelings and physiological arousal. Quincy Jones' "Bossa Nova" motivated movement and laughing in more than half of the participants. Bodily reactions such as "goose bumps" and "shivers" could be stimulated by the "Tuba Mirum" from Mozart's Requiem in 7 of 38 participants. In addition, the authors repeated the experiment seven times with one participant to examine intraindividual stability of effects. This exploratory combination of approaches throws a new light on the astonishing complexity of affective music listening. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

多点起爆网络装药及性能

为了研究多点起爆网络装药对爆轰波输出同步性及起爆能力的影响,以超细奥克托今(HMX)为主体炸药,硝化棉(NC)为粘结剂,(HMX/NC=95∶5)为沟槽传爆药装药,设计了一种3点同步刚性起爆网络,理论分析和测定了起爆网络在不同装药密度下的同步误差,对比试验了沟槽压装装药技术,对传爆药进行了表征,测试了起爆网络相关的爆轰性能,优化了起爆网络装药结构。结果表明,提高起爆网络装药密度能够增加起爆可靠性和降低同步误差,装药密度从1.17 g·cm~(-3)增加到1.47 g·cm~(-3),起爆网络的同步误差从300 ns降低到150 ns。以JH-2压装药柱作为输出端装药,超细HMX/NC传爆药作为沟槽装药,采用沟槽压装装药技术,可以使同步起爆网络的爆轰波输出同步性约为100 ns。     

红外图像预处理系统中模拟视频输出时序设计

一般图像处理系统是利用视频解码器从视频信号中直接分离出其同步和消隐脉冲,以达到系统处理同步的目的。由于本系统的模拟视频输入信号是非标准的,所以只能利用系统时钟信号作为系统同步的基准,从中获得模拟视频信号所需的同步及消隐信号,从而实现了一种红外图像预处理系统模拟视频输出的同步方案。该方案对于非标准视频图像输出显示系统的设计具有较好的借鉴意义。
