The purpose of this study is to develop a technique by which a physician may use a predetermined data base to derive a preliminary diagnosis for a patient with a given set of symptoms. The technique will not yield an absolute diagnosis, but rather will point the way to a set of most likely diseases upon which the physician may concentrate his efforts. There will be no reliance upon a data base compiled from poorly kept medical records with non-standardization of terminology. While this study produces a workable tool for the physician to use in the process of medical diagnosis, the ultimate responsibility for the patient's welfare must still rest with the physician.

This research was designed to investigate whether or not there are significant positive relationships between the total number of reasons production employees cite for staying with an industrial firm and measures of both job performance and job satisfaction. In addition, this study sought relationships between employee work values and both job performance and job satisfaction. Significant positive correlations have been established for tribalistic and existential values with production worker job performance. Further, significant positive correlations were shown for conformist values, and negative correlations for manipulative values with both job satisfaction and with the total number of reasons cited for staying with the firm. This study gives support to a situational theory of work motivation in which both job performance and satisfaction are dependent on the strength of employee job inertia.

The present study was concerned with seeking the opinions of Nigerian employers, Nigerians studying in the United States, and those studying in Nigeria concerning the need for human resource development in Nigeria. Data were collected through questionnaires mailed to selected Nigerian employers and to Nigerian students studying at various United States college campuses and at Nigerian university campuses. Problems of unemployment and critical shortages of skilled manpower continue to be rampant in Nigeria. The present investigation, through an analysis of questionnaire responses, seems to support the impression that little is really being done by Nigerian organization to upgrade and strengthen personnel talent in a planned and organized way. Most companies have no central long-range goal to guide their manpower development efforts. Much more time, effort, and expense are likely being devoted to the introduction of new operating systems or pieces of equipment than to the improvement of people.

The problem of this investigation is that of determining how double entry bookkeeping originated and evolved during the thirteenth, fourteenth and fifteenth century in mediaeval Italy and its influence on capital formation. The methodology of this study included the use of both primary and secondary sources of information. Great reliance was placed upon a direct examination of original documents found mainly in the State Archives of Genoa, Florence, Milan and Venice. Because this is basically a historical research, particular emphasis was given to the study and criticism of economic, political and religious conditions that most likely had a considerable influence on the creation and evolution of bookkeeping techniques and methods.
