Master’s thesis in the first part focuses on the effectiveness of communication in the selection of reference nodes during the anchor-free localization in WSN. In this part two anchor-free localization algorithms AFL and CRP are explored. Knowledge learned on the selection of reference nodes and communication complexities of these algorithms are used in the second part. The second part is aimed at eliminating weaknesses in communication and subsequently proposed a new algorithm for selection of references. The principle of the newly proposed algorithm CASRU (Centralized Algorithm for Selection of Reference Nodes) is based on the principle of CRP. CASRU algorithm builds logical tree structure and then filters the communication through it. New algorithm achieves much greater success in the selection in randomly distributed networks while reducing the amount of communication load.

Abstract: A CASE STUDY: U.S. LABOUR RELATIONS WITH THE TRADE UNION COUNCIL OF SOUTH AFRICA 1960-1973 The aim of this study is to examine US policies towards the South African labour movement through the American Federation of Labour - Congress of Industrial Organizations (AFL-CIO) and US official institutions, such as the State Department and the Labour Department of the United States, US universities etc. with particular focus on the period between the 1960s and mid-1970s. The study is shaped as a case study. In the study, the labour relations between the US and South Africa in the beginning of the 1960s and the middle of 1970s are examined by specifically focusing on TUCSA. The study is composed to six chapters. Following the first two chapters devoted for introduction and literature review, the developments of the post-Second World War era, such as the internationalization process of capital accumulation around the world, the cold war and the formation process of new international organizations are dealt with. The re-structuring process of the international labour movement under the cold war conditions and the development of overseas labour policies of the ICFTU and the AFL-CIO are also handled in this chapter. In the fourth chapter, the capitalist development process of South Africa in the post Second World War Era is discussed. The capital accumulation process under the apartheid and the developments within the labour movement are the main issues dealt with in this chapter. In the fifth chapter, US investments in South Africa between the beginning of the sixties and the mid seventies and the effects of these investments in the capital accumulation process of South Africa are evaluated. In the last chapter, the main focal point of the study, US labour relations with South Africa between the 1960s and the middle of the 1970s is focused on with particular reference to the relations between TUCSA and the US labour institutions including the AFL-CIO and other official organizations of the US. In the study, a historical framework is developed by focusing on developments in international scale and South African scale. In the third, fourth and fifth chapters, extensive literature on international labour, capitalist development of South Africa, labour history of South Africa and US investments in South Africa is given to elaborate the issue. The sixth chapter, which is the main chapter of the study, is relied principally upon archive materials of TUCSA.

In this dissertation project, I make three separate contributions to the study of the political economy of automation which center the agency of workers and society over technological change. The papers presented here each take a historical approach, both to contextualize modern debates over new technologies and to describe political responses that may have fallen out of contemporary awareness. In the first paper, I examine the origin of the term “automation” to reveal the ways that this concept has been shaped by social and political imperatives. I then propose a new definition and conceptualization of automation which respect this reality and open new avenues for research into this form of technological change. In the second paper, I examine the role played by the occupational structure of unions in determining their responses to automation. Drawing on a comparison of the cases of 1) the AFL-CIO and its Industrial Union Department and 2) New York Typographical Union No. 6 from approximately 1950–1975, I show that industrially-organized unions are more receptive of automation than are unions organized along craft lines. In the final paper, I examine the role that the different approaches to labor force control adopted by craft unions play in shaping both their responses to new technologies and their inclusion or exclusion of women workers. Through a comparison of the histories of the typographical unions in the United States and the United Kingdom over 150 years, I show that unions adopting an apprenticeship-based system of labor force control are both more resistant to new technologies and more exclusionary of women than are unions adopting a strategy of incorporation. Taken together, these papers show that workers and unions have been neither helpless cogs nor implacable wrenches in the machinery of technological change.

The focus of the study was an evaluation of a pregnancy prevention program. The study was designed to look at the adolescent pregnant and parenting population in the Adolescent Family Life Program, which serves about 300 clients in Southern California.
