Pervasive networks

• smart-radio aka cognitive radio technology to efficiently manage spectrum use and transmission power
• mesh routing protocols
• 4G may use OFDM , and also OFDMA.

In general, a generation is defined by the result of technology changes over a 10-15 year time frame. Thus, 4G would refer to whatever is deployed in the 2010-2015 period, assuming 3G deployment spans the 2000-2009 period.

Keywords: bulletin board, h-index, log-normal, online communities, power-law, radial tree, social networks, thread, weblogs

What is content analysis?

According to the scheme above, the content of comments was characterized by the three independent dimensions. The intention of the analysis was to reveal any emergent correlations among three attributes of comments collected in the dataset.

The affective dimension was generally quite straightforward and lent itself to comparatively easy classification. To probe the range between agreement and disagreement requires more careful judgment and usually involves more reading between the lines. The boundary between reflection and non-reflection was somewhat blurred for some occurrences of comments. Some comments showed no reflection as all; some comments demonstrated sufficient reflection while others appeared to possess marginal reflection.

Example of content analysis on the dataset of comments on the essay blogs.

Short review of Internet

Inventor of the internet technology packet switching, Leonard Kleinrock

" Dr. Leonard Kleinrock created the basic principles of packet switching, the technology underpinning the Internet, while a graduate student at MIT. This was a decade before the birth of the Internet which occurred when his host computer at UCLA became the first node of the Internet in September 1969."

Tim Berners-Lee

"In 1989 he invented the World Wide Web, an internet-based hypermedia initiative for global information sharing while at CERN, the European Particle Physics Laboratory. He wrote the first web client and server in 1990. His specifications of URIs, HTTP and HTML were refined as Web technology spread." He will serve as a keynote speaker at WWW2008.

A metric of Social Learning in blogs for higher education

• Yao-Jen Chang, Yao-Sheng Chang, Shu-Yu Hsu, Chiu-Hui Chen, Social Network Analysis to Blog-based Online Community, presented in International Conference on Convergence Information Technology 2007, Gyeongju, Korea. November 21~23, 2007. (EI)

Although the use of blogs has grown extensively in the past 5 years, our understanding of how to use blogs in an effective and meaningful way is still limited. In particular, acquiring more cohesive and useful information on the use of blogs is partially dependent on developing a consistent, comprehensive, theory-driven metric to assess quality and effectiveness. Considerable research has been carried out on the educational use of blogs. However, the use of blogs in education or knowledge management is more or less experimental and its effectiveness is far from clear. Research methods such as user survey and ethnography have been used in assessment but the perspective differences in surveys and methodological differences make it difficult to combine the results into a cohesive base of knowledge that can guide practice and education. Therefore, it is argued that a more comprehensive, theory-driven assessment tool is needed to advance our understanding of how to best use blogs in education. The purpose of this study, then, was to research, develop and test a multicomponent, theoretically driven metric to assess the effectiveness of blogs.

Method
Sample
The sample tested consisted of 36 undergraduate students enrolled in an introductory computer science course at a university in a metropolitan area. The students, mostly males with 5 females, ranging from sophomores to seniors. The data were collected and analyzed a month after the students finished the course.

Procedure
The blogs were part of a regular face-to-face course that met once a week for 180 minutes. Participation in social learning was worth 1/30 of the final grade, to minimize the negative impact of being graded yet provide incentives to become involved in the social learning through blogs. The blogs were intended to be student-led, and the teacher would only intervene if there were problems that students could not resolve, such as severe controversies and name calling.
