To address the criticism that the original IS SERVQUAL’s expectation measure is ambiguous, we test a new set of scales that posits that service expectations exist at two levels that IS customers use as a basis to assess IS ser...

Previous research on exposure to flood hazards suggests that individuals characterized by low social vulnerability are more likely to reside in coastal flood hazard zones than individuals of higher social vulnerability, but few studies have examined if similar exposure patterns can be observed in inland flood hazard zones. This paper examines differences in environmental justice implications be...

Iran is known as the most complex and varied country in southwest Asia, in terms of geography, vegetation, climate and consequently biological diversity. The rather high number of recorded endemic species of Fulgoromorpha in Iran indicates a high potential for speciation in some areas. In this study, in order to identify the endemic zones for Fulgoromorpha of Iran, three main biogeographic regi...

distinguishing productive zones of a drilled oil well plays a very important role for petroleum engineers to decide where to perforate to produce oil. conventionally, net pay zones are determined by applying a set of cut-offs on perophysical logs. as a result, the conventional method finds productive intervals crisply. in this investigation, a net index value is proposed, then; diffusivity equa...
