Today hundreds of millions of Internet users are using thousands of social Web sites to stay connected with their friends, discover new “friends,” and to share user-created contents, such as photos, ...videos, social bookmarks, and blogs. There are so many social Web sites, and their features are evolving rapidly. There is controversy about the benefits of these sites, and there are social issues these sites have given rise to. There are lots of press articles, Wikipedia articles, and blogs—in varying degrees of authoritativeness, clarity and accuracy—about some of the social Web sites, uses of the sites, and some social problems, and business challenges faced by the sites. In this paper, we attempt to organize the status, uses, and issues of social Web sites into a comprehensive framework for discussing, understanding, using, building, and forecasting the future of social Web sites.

This paper examines Webometric analysis the website of deemed universities in India. This study covered 125 deemed universities in India. The researcher identified and classified the four domains ...like State Universities, Central Universities, Deemed Universities and Private Universities. The researcher found that, out of 21 states, Tamil Nadu has a maximum of 28 (22.40%) universities, it is followed by Maharashtra 21(16.8%). The study calculated the Internal Link, External Link, back link and Size of the website. The study indicates that the numbers of backlinks are very low comparing to some of internal and external link. The researcher suggested that the websites of deemed universities need to attract more external links and impact factor by introducing novel and creative online sources and services and updates of news and research information.
Using basic accessibility standards, the presence or absence of essential usability features, and site accessibility statements, this study evaluates the accessibility of the home pages of the ...federal judiciary — those of the U.S. district, Appellate and specialty courts, the Administrative Office of U.S. Courts (AO), the Federal Judicial Center (FJC), and the main homepage of PACER, the federal judiciary’s e-filing and e-records access system. Software evaluations reveal detected instances of a narrow set of accessibility issues, including scripts with no accompanying functional text, images/server-side image maps with no text equivalents/descriptors, and inaccessible forms. Manual evaluations of Web sites show a high proportion (about 67 percent) of the home pages provided skip navigation links, whereas smaller proportions provided direct or indirect links to accessibility information — about 15 percent and 12 percent, respectively, as well as controls for manipulating font size (about 12 percent). Notably, a sizeable proportion (about 45 percent) of home pages provided direct or indirect links to a “BrowseAloud” explanation and download page, apparently in lieu of information on accessibility. Finally, content analysis of existing Web site accessibility pages and policy statements show a high degree of variation, with some being exceptionally detailed and informative, and some less so.
There are few works on the reproductive behavior of species of cribellale spiders. Even more scarce are studies of the reproductive behavior of representatives of the Desidae, such as the genus ...Metaltella Mello-Leitao, 1931. In this paper, we describe for the first time the reproductive behavior of Metahelia iheringi (Keyserling, 1891), a species that is characterized by complex genitalia in both sexes. We determined frequencies and durations of the behaviors in the different phases. Thirty virgin males were exposed to virgin females and the behaviors performed by each sex, as well as their frequencies, were recorded. Three phases were identified: pre-copulatory, copulatory, and post-copulatory. The most frequent behaviors were chelicera-palp rubbing, abdomen vibration and web-stretching by the male, and body-shaking and leg-tapping on the web by the female. When the male grabbed the female, she typically fell into a state of quiescence (the female remained motionless with legs in a semi-flexed position) and she remained so even after the male ended the copulation. Mating was characterized by low aggression by the female and a low incidence of cannibalism. In the post-copulatory phase, the male performed frequent behaviors such as abdomen vibration, sperm induction, and post-copulatory cohabitation. We discuss the possible implications of these behaviors in a pre- and post-copulatory sexual selection context. We also provide information that serves as a basis for future studies to understand the mechanisms involved in these behaviors.
