How do changes in human resource management practices influence employee engagement? A longitudinal study in a hotel chain in the Philippines

Drawing from social exchange theory, this study investigates how changes in human resource management practices influence and affect employee engagement in a hotel chain. Changes in human resource management practices were identified, and corresponding changes in the level of employee engagement were observed. One hundred forty-five employees from a hotel chain in the Philippines participated in a longitudinal study. Results show that improvements in human resource management practices, particularly in the areas of reward management and training and development, yielded positive and significant change in the level of employee engagement. Implications for human resource management, particularly in the hospitality and tourism context, are discussed.

AD-HOC principles of minimum energy expenditure as corollaries of the constructal law the cases of river basins and human vascular systems

In a recent paper [1] Reis showed that both the principles of extremum of entropy production rate, which are often used in the study of complex systems, are corollaries of the Constructal Law. In fact, both follow from the maximization of overall system conductivities, under appropriate constraints. In this way, the maximum rate of entropy production (MEP) occurs when all the forces in the system are kept constant. On the other hand, the minimum rate of entropy production (mEP) occurs when all the currents that cross the system are kept constant. In this paper it is shown how the so-called principle of "minimum energy expenditure" which is often used as the basis for explaining many morphologic features in biologic systems, and also in inanimate systems, is also a corollary of Bejan's Constructal Law [2]. Following the general proof some cases namely, the scaling laws of human vascular systems and river basins are discussed as illustrations from the side of life, and inanimate systems, respectively.
