An analysis of the key challenges to the widespread use of mediation in the Turkish construction industry
Purpose – The Turkish Ministry of Justice submitted the Draft Law on mediation in legal disputes, which was predicated on the European Council (EC) Directive on certain aspects of mediation in civil and commercial matters, to the Turkish Parliament in June 2008. Contentious arguments have followed on the provisions of the Draft Law as well as on the overall applicability of mediation in Turkey. The purpose of this paper is to examine the context surrounding the new mediation phenomenon in order to identify the key challenges awaiting its widespread use in the Turkish construction industry.Design/methodology/approach – Two complementary approaches were adopted in this paper. First, an analysis of the most debated papers of the Draft Law is carried out to determine the potential problems associated with the legislation by making comparisons with the EC mediation directive and mediation laws in some of the member states. Second, a series of structured interviews are organized among the Turkish construction i...
Bases of power and conflict intervention strategy: a study on Turkish managers
Purpose – This study aims to develop an influence perspective for managerial intervention in subordinates conflicts, which helps to represent various strategies identified in the literature in a single model. Managers' power base was then related to their intervention strategies. Drawing upon Social Judgment Theory, anchoring of subordinates positions is studied as a moderating variable. Design/methodology/approach – Thirty nine supervisors and their 165 subordinates from several organizations in Turkey filled out a questionnaire reporting power base of supervisor and their intervention strategy utilizing the critical incident technique. Findings – Referent power of superior led to mediation in subordinates' conflicts. However, mediation decreased while restructuring, arbitration, and educative strategies increased with increased anchoring of subordinates' positions. These latter strategies mostly relied on reward power of manager. Subordinate satisfaction was highest with mediation and lowest when superv...
Turbine blade temperature calculation and life estimation - a sensitivity analysis
Abstract The overall operating cost of the modern gas turbines is greatly influenced by the durability of hot section components operating at high temperatures. In turbine operating conditions, some defects may occur which can decrease hot section life. In the present paper, methods used for calculating blade temperature and life are demonstrated and validated. Using these methods, a set of sensitivity analyses on the parameters affecting temperature and life of a high pressure, high temperature turbine first stage blade is carried out. Investigated uncertainties are: (1) blade coating thickness, (2) coolant inlet pressure and temperature (as a result of secondary air system), and (3) gas turbine load variation. Results show that increasing thermal barrier coating thickness by 3 times, leads to rise in the blade life by 9 times. In addition, considering inlet cooling temperature and pressure, deviation in temperature has greater effect on blade life. One of the interesting points that can be realized from the results is that 300 hours operation at 70% load can be equal to one hour operation at base load.
