MBA Students’ Quality Improvement: The Correlation Analysis of Students’ Personal Traits and Attitudes towards Teaching Methods at a Chinese University

MBA education has become the fastest growing segment of education in China in recent years and a segment that can now be considered indispensible. However, how best to teach it has long been a source of debate. One of the key issues is how to match student traits with teaching methods. While engaged as teachers of marketing management, the authors collected data by questionnaire, carried out empirical research and data comparison, and undertook contingency analysis. It was found that different personal traits in students lead to different attitudes towards teaching methods. A student’s major in college, gender, and sector of employment has little influence on attitudes towards teaching methods, while age, the most sensitive factor, plays the biggest role, followed by job and class. Therefore, these factors should be taken into consideration when arranging classes, developing the curriculum, and planning teaching methods.     

区域一体化对城市创新能力驱动研究——基于长三角的实证分析

长三角更高质量一体化发展标志着各种资源要素在长三角区域内的配置效率将进一步提升,有利于形成更强的区域创新能力。本文基于2005—2017年长三角城市统计数据,考察了区域一体化对城市创新能力的驱动作用,并对其中的影响机制和异质性进行了深入分析。结果显示：(1)区域一体化对长三角城市创新能力具有显著的促进作用。(2)机制分析发现,一体化伴随的产业集聚并未形成创新能力提升机制,但一体化推动的区域内部产业转移机制有效提升了城市创新能力。(3)异质性分析表明,长三角区域一体化对非核心城市、欠发达城市、低财政分权城市具有更为显著的城市创新能力驱动作用。

数据驱动的微信用户信息行为时间特征研究

[目的/意义]相对于传统的信息行为分析，数据驱动的信息行为研究更注重数据的外在性与客观性，所得的结果能够更为全面地认识用户信息行为本质特征。[方法/过程]通过自行构建的APP实现对微信用户分享和阅读行为记录的采集，并对微信用户信息行为的时间特性进行系统的分析。[结果/结论]结果表明：微信用户日常信息行为存在显著的假日效应，但是在信息行为时间间隔分布上存在明显厚尾现象和很强的阵发性，预示着微信用户信息行为具有较高的复杂性和不确定性，无法对其产生过程实现有效的预测；此外，微信用户所分享的内容具有很强的时效性，多数内容在微信中能够得到及时的传播，但传播链长度显著受分享内容主题的影响。     

Moving beyond the anthropos and reclaiming the geo in intercultural communication: The transculturation of the martial art practice of Aikido

This ethnographic study examines the practice of Aikido, a martial art style originating from Japan, by a community of non-Japanese practitioners in the southwestern region of the United States. This paper recounts the second nature-making of the art's skillful responsiveness as a thing to be explained from the ground, rather than leaving its cultural dynamics and their appropriative relations unchallenged as a relatively homogenous process of globalization and increased contact. In the case of Shining Energy (a pseudonym), the “taking” of another's cultural elements and “making” it a fully habituated and naturalized way of moving and being (second nature) are predicated on geo-making, the production of ontologizing resources (first nature) that enable culturally sanctioned modes of somatic engagements with the world. The process of appropriating Aikido entails an inversion between the figure and ground that foregrounds the geo-making of the ground/field for activity itself.

How does collaboration affect researchers’ positions in co-authorship networks?

Collaboration usually has a positive effect on researchers’ productivity: researchers have become increasingly collaborative, according to recent studies. Numerous studies have focused on enhancing research collaboration by recommendation technology and measuring the influence of researchers. However, few studies have investigated the effect of collaboration on the position of a researcher in the research social network. In this paper, we explore the relationships between collaboration and influence by social analytical methods, which are pertinent to analyzing the network structure and individual traits. We evaluate three aspects of the researchers’ influence: friendship paradox validation, social circle, and structure of a researcher's ego network. Furthermore, the ”six degrees of Bacon number” theory, generalized friendship paradox, and triadic closure theory are introduced to support our analysis. Experimental results show that collaboration can help researchers increase their influence to some extent.
