Abstract: | The relationships between age, aspects of tenure, locus of control, job involvement, and boundary spanning behaviour (B.S.B.) were examined using path analysis for 281 scientists and engineers. It was found that locus of control and age were significant determinants of job involvement. It was also shown that locus of control and job involvement were significant determinants of B.S.B. These findings are discussed relative to previous research on locus of control, job involvement, and B.S.B. Finally, new research designs are advocated which incorporate task characteristics, role dynamics constructs, and environmental uncertainty as determinants of B.S.B. |
