Forms of Nitrogen (NO 3 - -N; NO 2 - -N and NH 2 CONH 2 -N) and their relations to A.O.U. in the Indian coastal waters of Arabian Sea

The distribution of three important dissolved forms of nitrogen, viz. nitrate, nitrite and urea in the surface and bottom water samples collected from 27 selected hydrographic profiles, in the Arabian Sea, along the west coast of India is described. Of the three forms, nitrate concentrations were the highest and comparatively higher concentrations were observed in the bottom water. Decomposition of organic matter resulting in the release of the thermodynamically stable nitrogen species, i.e. nitrate, may be the major factor resulting in higher nitrate concentrations at these depths, where the water is also characterized by low values of dissolved oxygen and temperature. The significant positive correlation between A.O.U. and nitrate of the bottom water samples emphasizes the role of oxidative decomposition of organic matter which plays an active role in reducing the oxygen concentrations below the theoretical values since at this depth ( 200 m) the net production is taken to be zero. This is also evidenced by the negative correlation of nitrate with dissolved oxygen and temperature, for the bottom samples

Electron-Phonon Interaction Within the Framework of the Fluctuating Valence of Copper Atoms — a Theoretical Model for High Temperature Superconductivity

Electron-phonon interaction is considered within the framework of the fluctuating valence of Cu atoms. Anderson's lattice Hamiltonian is suitably modified to take this into account. Using Green's function technique tbe possible quasiparticle excitations' are determined. The quantity 2delta k(O)/ kB Tc is calculated for Tc= 40 K. The calculated values are in good agreement with the experimental results.

Emotional Intelligence As A Determinant Of Conflict Style Adoption Of Managers: A Theoretical Perspective

Successful management is dependent heavily on the manager’s ability to handle conflict effectively. The workforce has been increasingly becoming diversified vis-à-vis the gender, culture and ethnicity. The present work environment has in itself contributed to sowing seeds of conflict with greater diversity, hostility, complexity and newer business competencies in the work context.The classic study of Mintzberg’s Managerial roles approach (1973) also says that a manager has to spend sufficient time and energy in solving conflict as he has to take roles as a negotiator, and dispute handler. An understanding of the conflict and role that it plays in influencing employee behavior constructively or destructively is immense. Therefore conflict when left unmanaged can lead to diminished cohesiveness amongst employees, productivity and reduced organizational fitness. To manage conflict effective conflict resolution strategies that have constructive outcomes is called for. Conflict resolution style theorists opine that collaborative or integrative style, where there is high concern for task and people is considered to give positive individual and organizational outcomes, while the withdrawing /avoidance style and forcing / dominating style are considered to be ineffective in managing conflict. Though managers have typical preferences in the styles followed it need not necessarily be the typical response as it depends on the context, power relationships, emotions etc. The adoption of conflict styles of managers however is dependent on variables like gender orientation, cultural values, personality orientation, underlying relationships – public/private. The paper attempts to draw the importance of managing conflicts at workplace positively and the need for effective conflict resolution strategies. The conflict style adopted and the variables that affect the adoption of each style are discussed and possible interventions at the workplace are suggested
