The role of engagement on stakeholder's satisfaction with the destination marketing organisation's performance

In the tourism literature there has been a lack of research related to stakeholders' satisfaction with destination marketing organisations (DMO). This study addresses this research gap, in the context of the national tourism office of Oman, by investigating the relationship between stakeholder's perceptions of DMO performance and their overall satisfaction with the DMO. Conceptually the study found DMO engagement with stakeholders to partially mediate satisfaction, a finding of relevance to destination marketers in other parts of the world. From a practical perspective the research was supported by the Oman national tourism office, which has only been in operation for 10 years.

Role of Melt Convection on the Thermal Performance of Heat Sinks with Phase Change Material

The role of melt convection oil the performance of beat sinks with Phase Change Material (PCM) is presented in this paper. The beat sink consists of aluminum plate fins embedded in PCM and heat flux is supplied from the bottom. The design of such a heat sink requires optimization with respect to its geometrical parameters. The objective of the optimization is to maximize the heat sink operation time for the prescribed heat flux and the critical chip temperature. The parameters considered for optimization are fin number and fill thickness. The height and base plate thickness of heat sink are kept constant in the present analysis. An enthalpy based CFD model is developed, which is capable Of Simulating phase change and associated melt convection. The CFD model is Coupled with Genetic Algorithm (GA) for carrying out the optimization. Two cases are considered, one without melt convection (conduction regime) and the other with convection. It is found that the geometrical optimizations of heat sinks are different for the two cases, indicating the importance of inch convection in the design of heat sinks with PCMs.
