Many of these studies indicate that strategic planning helps organisations to improve their performance. However some studies have suggested that strategic planning has either no effect or a negative effect on performance. Some studies have suggested that external environment moderates the relationship between strategic planning and performance. However the moderation effect of environment has not been examined in detail in the empirical studies. This study examines the relationship between strategic planning and performance and also examines the moderating effects of environmental dynamism and hostility. 1 Assistant Professor, Indian Institute of Management Kozhikode, IIMK Campus 2013-01-01T00:00:00Z http://dspace.iimk.ac.in:80/xmlui/handle/2259/748 Patterns of PED Test Sanctions in Professional Sports– Baseline and Implications for Research Dhayanithy, Deepak This paper establishes an empirical ground for the exploration of PEDs in professional sport, and the research implications. We use athlete level testing and sanctions data of 70 sports disciplines between 2001 and 2012, conducted by USADA (United States Anti-Doping Agency), and examine the sport specific effects, calendar year effects and career stage effects on the USADA sanctions rate – both in univariate studies as well as in multivariate Cox proportional hazards regressions. We find that certain sports such as cycling, weightlifting and track & field do have significant and positive effect on the USADA sanction rate. On the other hand, many seemingly lower and higher than average sanctions rate, like for soccer and basketball are not statistically significant, that is they don’t move the baseline hazard rate up or down. There is a distinct inverted U relationship between career stage and sanctions rate, with a kink to a much higher sanctions rate in the veteran years of an athlete’s career. Given these results, it becomes very important that we make careful study of the determinants and consequences of the use of PEDs in professional sport by athletes. This paper provides the empirical basis for the study of PEDs use by professional athletes, setting out important avenues for further empirical and theoretical research in the field. 1 Assistant Professor of Strategic Management, Indian Institute of Management Kozhikode 2013-01-01T00:00:00Z http://dspace.iimk.ac.in:80/xmlui/handle/2259/747 What Drives Performance- Diversity,Selectivity, Experience or Methodology? Dhayanithy, Deepak Relegation is a serious concern for soccer clubs in the bottom echelons of a lucrative league such as the EPL. The key performance criterion for newly promoted clubs is to avoid relegation, and it is important for these clubs to invest in their squads and build up their resources. Previous International Business studies have studied the link between resource positions and firm performance in cross sectional data settings. However, a specific performance outcome such as relegation may not occur in one cross sectional snapshot, only to occur subsequently. This article explores the resource drivers of club performance in a time-to-event Cox regression framework, where the event is relegation; and compares the hypotheses testing results with results obtained from Logistic regression analysis. We find resources diversity is important in the Cox regressions whereas it is significant in only one particular definition of the observation time window in Logistic regressions, which is difficult to establish apriori. We call for a triangulation of cross sectional studies of performance events with an analysis in the time-to-event setting. 1 Assistant Professor of Strategic Management, Indian Institute of Management Kozhikode 2013-01-01T00:00:00Z http://dspace.iimk.ac.in:80/xmlui/handle/2259/746 On Modeling the Step Fixed-Charge Transportation Problem Ram Kumar, P N Fixed-charge transportation problem (FCTP) deals with determining optimal quantities ofgoods to be shipped and the routes to be used to satisfy the customers’ demands at minimaltotal cost. The total cost contains a fixed component which is incurred for every route that ispart of the solution along with the variable cost that is proportional to the amount shipped. Stepfixed-charge transportation problem (SFCTP) is a variant of the FCTP where the fixed costsfollow a step function. Staircase cost structure is very common in the shipping industry,national postal services and couriers, and materials management. In this work, we propose aMILP model for SFCTP. After explaining the mathematical model in sufficient detail, wedemonstrate its applicability on a small numerical example. Using extensive computationalexperiments, we conclude that the problem is a very hard problem with much “higher degree”of polynomial complexity.We also report that the number of steps in the fixed componentappears to be the dominant factor that significantly affects the computational time. Though theproposed MILP model is applicable for SFCTP, with minor modifications, it can be generalizedand used for other network optimization problems that warrant modeling of staircase coststructures.
