Social Network Analysis Using Author Co-Citation Data

This study examines the social network of scholars in the field of Communication by using author co-citation data. A matrix containing the number of co-cited documents between pairs of authors is created for social network analysis of scholars who are on the editorial board of Journal of Communication, and the networked map of the scholars is used to visualize the knowledge structure of the field by identifying groups of authors who are more central than others. Social Science Citation Index (SSCI) is used to collect the author co-citation data, and UCInet is employed for social network analysis as well as network visualization

Regulation, trust, and cronyism in Middle Eastern societies: The simple economics of 'wasta'

Despite being a fixture of everyday life in the Arab world, wasta, which may be thought of as special influence by members of the same group or tribe, has received little attention from social scientists. Our casual empiricism suggests that wasta is an important determinant of how economic activities are organized and resources are allocated in Middle Eastern societies, yet economists, even those who specialize in work related to the Middle East, have not addressed the issue of wasta. With this paper we provide a modest beginning to filling that void. Specifically, we use the history of wasta, Hayek's concept of extended order and Coase's work on the nature of the firm to draw inferences regarding the existence of wasta and its persistence in Arab societies

Omaha Unemployment Feasibility Study: Final Report

The research reported here was designed to test the feasibility of a practical approach to the reduction of unemployment, particularly among Negroes. The need for the particular kind of emphasis used in this approach was recently stated by the director of the U.S. Employment Service in pointing out the need to obtain more understanding of the things that make the community tick, that keep it from solving its problems, and that lead to the discovery of the real barriers to coordination..

A generalized method for multiple robotic manipulator programming applied to vertical-up welding

The application is described of a weld programming algorithm for vertical-up welding, which is frequently desired for variable polarity plasma arc welding (VPPAW). The Basic algorithm performs three tasks simultaneously: control of the robotic mechanism so that proper torch motion is achieved while minimizing the sum-of-squares of joint displacement; control of the torch while the part is maintained in a desirable orientation; and control of the wire feed mechanism location with respect to the moving welding torch. Also presented is a modification of this algorithm which permits it to be used for vertical-up welding. The details of this modification are discussed and simulation examples are provided for illustration and verification
