A metric analysis of blogs on library and information science (LIS) between November 2006 and June 2009 indexed on the Libworm search engine characterizes the community's behavior quantitatively. An analysis of 1108 personal and corporate blogs with a total of 275,103 posts is used to calculate survival rate, production (number of posts published), and visibility via such indicators as links received, Technorati authority, and Google's PagePank. Over the study period, there was a 52% decrease in the number of active blogs. Despite the drop in production over this period, the average number of posts per blog remained constant (14 per month). The most representative blogs in the discipline are identified. The emergence of such platforms as Facebook and Twitter seems to have meant that both personal and corporate blogs have lost some of their prominence.  相似文献

The successful encapsulation of human hepatocellular carcinoma (HepG2) cells would greatly assist a broad range of applications in tissue engineering. Due to the harsh conditions during standard chitosan fiber fabrication processes, encapsulation of HepG2 cells in chitosan fibers has been challenging. Here, we describe the successful wet-spinning of chitosan-alginate fibers using a coaxial flow microfluidic chip. We determined the optimal mixing conditions for generating chitosan-alginate fibers, including a 1:5 ratio of 2% (w∕w) water-soluble chitosan (WSC) solution to 2% (w∕w) alginate solution. Ratio including higher than 2% (w∕w) WSC solution increased aggregation throughout the mixture. By suspending cells in the WSC-alginate solution, we successfully fabricated HepG2 cell-laden fibers. The encapsulated HepG2 cells in the chitosan-alginate fibers were more viable than cells encapsulated in pure alginate fibers, suggesting that cross-linked chitosan provides a better environment for HepG2 cells than alginate alone. In addition, we found that the adhesion of HepG2 cells on the chitosan-alginate fiber is much better than that on the alginate fibers.  相似文献

The tools used in learning processes are in a continuous state of flux. One of the most significant changes is the application of Information and Communications technologies (ICTs) to educational contexts. This provides new possible ways to carry out learning activities, new learning services, the possibility to use new kinds of contents and activities, etc. However, ICTs have not provided as many advantages as they were supposed to, so changes are necessary. In this context, a new set of tools, Web 2.0, offers a new way to understand the Web, in which the user is the centre. Further, users can cooperate in order to define contents. This concept is also applied in technology-mediated learning but there are important problems when one tries to integrate such tools and concepts with existing systems. This paper explores the integration of these tools in traditional learning environments, the various possibilities and their advantages and drawbacks. After that, an interoperability scenario is described and two experiences are presented to show how 2.0 tools can be integrated in learning activities, and its effect in educational process.  相似文献

This paper focuses on institutionally powered personal learning environments (iPLEs). The concept of the iPLE can be seen as a way universities can incorporate learner-centred approach into the architecture of their technology-enhanced learning environments. The aim of this paper is to pose that there are other ways to learn complementary to virtual learning environments, such as using distributed Web 2.0 tools from personal learning environments (PLEs). With that aim in mind, this paper presents an exploratory study with two different iPLE configurations, analyses how they modify the learning–teaching process, and reports their perceived usefulness from the students' point of view. These two case studies were carried out by a research group of educational technology from a Spanish university in graduate and postgraduate courses. As reported by other case studies, the results revealed that students use the environment basically in the academic context and this usage is conceived as another time and effort requiring task. This fact can be observed in the low level iPLEs customization. The overall conclusions we can extract are, on the one hand, that the new environment to integrate informal and formal learning should be flexible and adaptable to the student's needs and preferences and, on the other hand, that academic tools might someday become personal tools.  相似文献

In this article, we, colegas/colleagues of color, explore the ways in which the literary and artistic contributions of Gloria Anzaldúa, Octavia Butler, and Frida Kahlo have inspired, nurtured, and profoundly influenced our personal and professional lives as academics. We underscore the importance of mentoring for women of color in academe and educational leadership, particularly the psychosocial functions associated with informal mentoring. Further, we discuss how the lives and contributions of our “mentors” impacted our scholarly journeys, framed by third-wave and decolonial woman-of-color-feminism. In this article, we offer an alternative consideration for women of color in search of suitable mentors, concludes by sharing the lessons we learned from the artists. Thinking about mentoring from the position of alterity adds to the general mentoring discourse and serves to inspire women to consider alternatives when seeking mentorship to reach academic and professional goals.  相似文献
