“陌生人”视角下社会化媒体与网络社会“不确定性”研究

本研究通过社会心理学的"陌生人"视角,分析了网络陌生人的人际不确定性和情感正向性特征,讨论了陌生人复杂互动如何导致社会化媒体内舆论领袖和议题涌现,并实现情感和信息的极化与放大;再通过"不确定性"的理论视角,讨论这种陌生人复杂互动如何通过社会化媒体间共振、潮涌,导致社会化媒体传播和动员能力的突生性和意外效果,进而生成网络社会的不确定性。     

中国的印度洋海权战略

印度洋具有重要的地缘战略地位,实施印度洋海权战略为解决中印领土争端、南中国海和太平洋海权问题开辟了第二条战线,是维护中国海权的一个重要措施。中国的印度洋海权战略以海军建设为中心,以西藏、云南和新疆为战略支点,构建连接中国和印度洋的石油走廊、金融走廊、文化走廊。     

Document delivery and resource sharing: A collaborative consortium approach by Indian agricultural libraries

Indian Agricultural Libraries are exploring new ways and collaborations to fullfil the information need of their patrons through resource sharing and delivering documents using online platform accessible 24X7. The article discusses Inter Lendig and Document Delivery Services (DDR) facilitated through a collaborative consortium Journal Gateway called CeRA under Indian National Agricultural Research System. CeRA the (Consortium for e-Resources in Agriculture) provides a platform for online acess to e-journals and inter lending. DDR Services has been established to share resources subscribed by individual libraries as well as consortium journals using the web portal. The article also discusses of the use of DDR services by patrons of the first Indian Agricultural University in the country. Reports that the student community were most active in using the platform for inter library loan and document request in comparison to the faculty researchers who were less dependent on document from other libraries.

U.S. Federal Indian Policy: An Essay and Annotated Bibliography

Federal Indian policy in the United States historically reflects both the hard-headed pragmatism of the nation and its quixotic romanticism. Researchers can identify roughly drawn policy epochs and policy motivations, but there were no clean slates as policy shifted. The legal history of a tribe reflects the accumulated—and often contradictory—impact of changing federal policy. Complexity was added to the government's approach by the application of single-minded policies to the exceedingly diverse native groups within the nation's borders. An understanding of evolving federal policy offers useful insights and a basis for creative legal theories.     

Exploring Dominant Types of Explanations Built by General Chemistry Students

The central goal of our study was to explore the nature of the explanations generated by science and engineering majors with basic training in chemistry to account for the colligative properties of solutions. The work was motivated by our broader interest in the characterisation of the dominant types of explanations that science college students use to make sense of phenomena under conditions of limited time and limited explicit knowledge about a topic. Explanations were collected in written form using two different quizzes that students completed under time constraints at the end of a two‐semester general chemistry course. Our study revealed that students’ ability to generate causal/mechanical explanations depended on the nature of the task. In general, students were more inclined or able to generate mechanistic explanations to account for boiling‐point elevation and freezing‐point depression than to make sense of osmotic flow. The analysis of the types of causal explanations built by the study participants suggests that students may be biased towards some causal models or explanatory modes characterised as causal‐additive and causal‐static in our work. A large proportion of the students built non‐causal teleological explanations to account for osmotic flow. None of the participants in our study used a dynamic model of matter as the basis for their explanations of any of the relevant phenomena; the idea of an underlying random process that is taking place at all times giving rise to emergent properties and behaviours was completely absent from their intuitive reasoning under conditions of limited time and knowledge.     

Creating case studies of practice through Appreciative Inquiry

Taking a positive view is a fruitful way to prompt educators to reflect on and to develop their practice. Teachers, teacher educators and children bring a wide range of ideas that provide a powerful basis for developing understanding of the complexities of classroom practice. Using appreciate inquiry the authors show how they developed their understanding of professional development as they worked with groups of teachers who investigated their science teaching practice with young children and produced case studies of practice. The authors also show how the roles and ideas of themselves as university tutors were challenged and emerged to suit the range of contexts involved. Their view of Continuing Professional Development was influenced by the lived experiences of the teachers and themselves. They worked to systematise learning through identifying commonalities of experience and reflection along four dimensions: creating spaces for growth; working with emergent purposes; action research as rhizomatic growth; and collaborative and collective action. The rich variety of outcomes shows the value of creating space for growth for children and for adults. The energy and enthusiasm liberated motivated the participants to explore their worlds in ways that were difficult to predict at the start of the project.
