The "Factorial Ecology of Dallas County" deals with the differentiation of census tracts based on combinations of census tract variables for Dallas County. The study examines this differentiation, using five factors which are analyzed in relation to concentric zone and sector theory. All of the analyses are based upon data which are available by census tract from the 1970 national census.

Work motivation is one of basic methods of management, it is a specific scientific field containing many scientific theories. An Effective motivation must be focused on characteristics of both the subject and the target. The greatest economic subject is the national economy with two cooperating sectors -- private, based on private ownership, and public sector financed by public sources. People engaged in one of these sectors can have various ideas and claims. For all managers, it is essential to know these claims and interests in order to apply a convenient motivation method. The aim of the proposed diploma thesis is to contribute to a solution of the following question -- is it necessary to motivate employees in public sector differently than employees in private sector? For this purpose I designed and evaluated a questionnaire. In last chapter, I suggest what measures are most convenient in order to reach the most effective motivation of employees in a public sector as well as in a private sector.
