微信群会话网络结构及成员角色划分研究

[目的/意义]微信群内部会话交流过程存在着复杂的网络结构,探究微信群内部网络结构特征并划分成员角色对研究微信群中信息传播及成员角色关系具有重要意义。[方法/过程]以虚拟社区理论和会话分析理论为基础,以真实微信群内部的会话数据作为研究对象,通过构造成员活跃度划分微信群成员角色类型,基于成员相互回应行为与共同回应行为设计成员关联强度算法并构建会话交流网络,采用社会网络分析和内容分析方法对其静态结构特征及动态结构演化进行分析。[结果/结论]微信群内部成员角色及地位具有差异性,会话交流过程呈现出明显的中心性态势;微信群会话交流网络符合六度分割理论,具有小世界效应的特征;微信群会话交流网络具有动态演化性且核心成员具有时间依赖性。     

Profile and Motivations of Registered Whole-Body Donors in Turkey: Istanbul University Experience

Little is known regarding the profiles of whole body donors in Muslim majority countries where donation is scarce. Therefore, this study aims to profile registered donors in Turkey by means of a survey. The explored data could be used to improve ongoing campaign efforts and ethical practices such as commemoration services. Registered donors of the donation programs at the two faculties of medicine of Istanbul University were compared with the national population and a cluster analysis was performed to reveal any concealed sub-groups. Data from 188 respondents were analyzed. The majority of registered donors were married (42%), male (65.4%), aged over 50 years (76%), held a tertiary education degree (49.7%), and were irreligious (58.5%). Cluster analysis revealed two groups with significantly different educational levels, marital statuses, and religious choices. Regarding whether their bodies could be used for education or research, the majority (64.5%) of the respondents left the decision to the anatomy department. Similarly, 73.8% approved indefinite use of their organs, body parts and/or skeletons. The respondents were also willing to share their medical history (94.2%) and personal information (81.6%) if needed. Motivational themes for body donation including usefulness, impermanence, religion, awareness, and kinship were devised after a thematic analysis. Among the respondents, 56.5% were registered organ donors and 63.3% were frequent blood donors. The results of this study provide data that may help revising informed consent forms, developing and implementing thanksgiving ceremonies, and selecting additional targets for supporting body donation campaign activities such as organ and blood donation units.     

我心目中的教育学

我在《读书》2003年第10期发表了短文《教育学的尴尬》,引来了一些论者公开、私下的支持或批评,被认为表达了我对中国教育学的"不满"、"质疑"、"失望和轻蔑"[1]。我感谢这些论者,他们的评论促使我去反思自己的论述,并启发我进一步去思考中国教育学究竟该何去何从。     

Competency, capability, complexity and computers: exploring a new model for conceptualising end-user computer education

Notions of competency have dominated the computer education literature, and have underpinned Competency‐Based Training (CBT) in information technology at all levels of education and training. The emergence of counter‐narratives underpinned by the capability movement, have as yet had minimal impact on practice in computer education. New discourses in educational theory and practice which are founded on non‐linear approaches to learning and teaching provide added impetus to engage in the competency/capability debate, and re‐examine our approaches to computer education. This paper explores complexity theories and demonstrates how complexity's pedagogical implications can lead to new models for understanding computer learning and teaching. A new model for conceptualising end‐user computer education is presented that was derived from a three‐year action research initiative with pre‐service teachers.     

3-D scattering of obliquely incident plane p waves by alluvial valley embedded in layered half-space

The indirect boundary element method(IBEM) was established to solve the problem of 3-D seismic responses of 2-D topographies,by calculating the free-field responses with the direct-stiffness method and simulating the scattering wave fields with the dynamic Green’s functions of moving distributed loads.The proposed method yields accurate results,because the 3-D dynamic stiffness matrixes used are exact and the fictitious moving distributed loads can be acted directly on the interface between the alluvial valley and the layered half-space without singularity.The comparison with the published methods verifies the validity of the proposed method.And the numerical analyses are performed to give some beneficial conclusions.The study shows that 3-D scattering by an alluvial valley is essentially different from the 2-D case,and that the presence of soil layer affects not only the amplitude value of surface displacements but also the distribution of surface displacements.     

Evaluation of mobile assessment in a learning management system

This article discusses the problem of using and delivering educational content from the Moodle learning management system to mobile devices. The primary goal of this study was to investigate the students' habits, motivations and technical possibilities in order to incorporate mobile‐learning activities in the e‐learning process. A mobile quiz has been chosen as an activity to be delivered on mobile devices. The developed mobile quiz application was integrated into Moodle. The application interface was tailored to various types of mobile devices aiming to foster mainstreaming of mobile technologies in e‐learning. For the purposes of the evaluation, an experiment was conducted within the e‐learning system at the Faculty of Organizational Sciences, the University of Belgrade. Data were obtained from the students who attended e‐learning courses in the area of e‐business. Research findings have shown that integration of the mobile quiz application into Moodle improves students' results and increases satisfaction and motivation for using mobile devices in their learning process.     

Kiva Microloans in a Learning Community: An Assignment for Interdisciplinary Synthesis

Learning communities can strengthen early undergraduates’ learning, but planning them can be daunting for instructors. Learning communities usually rely on integrative assignments that encourage interdisciplinary analysis. This article reports on our experiences using microloans as an interdisciplinary assignment in a learning community that united algebra with world literature. Students used the microfinance website www.kiva.org to make small loans of real money to entrepreneurs in low-income countries. Four themes emerged from student reaction to the assignment: awareness of Africa, community impact, mathematical consciousness, and productive collaboration among students. Our reflections suggest that microfinance assignments may support integrative learning across many other disciplines.
