A study on the organisational commitment of professionals with respect to various aspects of organisational socialisation

Organisational commitment of various groups of professionals seems to be moderated by the differences of the groups as well as of the socialisation experiences Demographic variable ‘age’ and the semi-structural variable ‘experience’ cause a difference in the level of commitment. Similarly, the professional and organisational differences moderate the level of commitment. From the point of view of the organisations, the socialisation experiences if differ can be used as tool to process and enhance the level of commitment of professionals of various groups.The ‘Socialisation effect’ does not depend on the professional or demographic differences. Socialisation level is moderated only by the organisational specialities. It is purely an organisational variable. However, the difference in the socialisation levels as found among the professionals can cause a significant difference in the levels of organisational commitment of professionals

Studies on Some Aspects of the Physics of the Early Universe Using Gravitationally Coupled Scalar Field –

This thesis deals with some aspects of the Physics of the early universe, like phase transitions, bubble nucleations and premodial density perturbations which lead to the formation structures in the universe. Quantum aspects of the gravitational interaction play an essential role in retical high-energy physics. The questions of the quantum gravity are naturally connected with early universe and Grand Unification Theories. In spite of numerous efforts, the various problems of quantum gravity remain still unsolved. In this condition, the consideration of different quantum gravity models is an inevitable stage to study the quantum aspects of gravitational interaction. The important role of gravitationally coupled scalar field in the physics of the early universe is discussed in this thesis. The study shows that the scalar-gravitational coupling and the scalar curvature did play a crucial role in determining the nature of phase transitions that took place in the early universe. The key idea in studying the formation structure in the universe is that of gravitational instability.
