Males in many taxa are known to exhibit behavioural plasticity in response to the perceived intensity of sperm competition, reflected in Drosophila melanogaster by increased copulation duration following prior exposure to a rival. We tested the prediction that males do not adjust their copulation effort in response to the presence of a competitor in Drosophila species where there is little or n...

Although equilibrium competitive radioligand binding studies are often used to characterize hormone and neurotransmitter receptors, the kinetics of such experiments have not been extensively explored. The interactions of the radioligand and competitor with the receptors can be described by two differential equations which can be solved to yield a single equation describing the binding of the ra...

IS Success Model by DeLone and McLean (1992, 2003) has been used to explain how information systems create value for organizations. However, IS Success Model does not fully address how users perceive value of an information system. It assumes that the information quality, system quality, and service quality automatically generate user satisfaction. Users will not be satisfied with information s...

Iterative development is a common characteristic of agile methods. It is important to understand how the adoption of an iterative process provides business value, and how this value can be used to buy management support to implement other agile techniques. This paper exposes to the community an experience report of a large government agency’s migration from a Waterfall process to an iterative m...

INTRODUCTION This paper examines a number of US chemical industry incidents and their effect on equity prices of the incident company. Furthermore, this paper then examines the contagion effect of this incident on direct competitors. METHOD Event study methodology is used to assess the impact of chemical incidents on both incident and competitor companies. RESULTS This paper finds that the ...

concerns about environmental issues have revealed the necessity of developing changes in the field of consumption and production. Introducing green products as a substitution to common products in the market, which harm to human health and environment and also enriching the culture of green consumption in the society and recognizing effective factors can be solutions for environmental prob...
