Measuring the Sensitivity of Initial Conditions in Individual Procedures for Finding First Professional Employment - Proposal for a Process and Application. Individual procedures for obtaining first professional employment are influenced simultaneously by social determinism, chance and individual stratégies. The question is how to unravel these different factors. Starting with the central opposition between chance and determinism -- where strategies create possibilities -- this study proposes an analysis within the framework of bounded chaos. First, a method is proposed for the measurement of sensitive initial conditions (SCI) based on Lyapunov powers associated with obtaining first professional employment. Second, this study shows that the SCI measure permits one to examine the respective roles of chance, determinism and strategy. It then suggests that the SCI measure is a better tool for counseling on scholastic and professional orientation than surveys of entire classes conceming first jobs. The latter remain better adapted to counseling and evaluating educational institutions and curriculums.
