In this paper we study the optimal forest conservation policy by a hyperbolically discounting society. Society comprises a series of non-overlapping imperfectly altruistic generations each represented by its own government. Under uncertainty about future pay-offs we determine, as solution of an intergenerational dynamic game, the optimal timing of irreversible harvest. Earlier harvest occurs an...

The present study integrates the literature on social loafing and organizational citizenship behavior (OCB). The authors examined the roles of personality, motives, and contextual factors in influencing the work behaviors of OCB and social loafing. In a sample of 341 individuals working in project groups, with data collected over 3 time periods, the authors found that conscientiousness was nega...

A generalized model has been developed for the prediction of pressure drop and flooding in packed columns in which gas and liquid flow countercurrently. The model has been validated for a wide variety of packings, both random and structured. A single mathematical expression is used to describe all flow regimes: dry gas, irrigated gas flow below the load point, loading region, and flooding. The ...

The interest in zirconium-89 (89Zr) as a positron-emitting radionuclide has grown considerably over the last decade due to its standardized production, long half-life of 78.2 h, favorable decay characteristics for positron emission tomography (PET) imaging and its successful use in a variety of clinical and preclinical applications. However, to be utilized effectively in PET applications it mus...

versa can also happen. However, the co-existence of a patch of morphea mimicking as Leprosy patch in an underlying case of neuriticleprosy, can be very misleading. We present a case with glove and stocking anaesthesia and peripheral nerve enlargement with a single large hypopigmented, non-anaesthetic macule on trunk, clinically diagnosed as Hansen's disease (Borderline Tuberculoid BT). Slit ski...
