In Qatar, cardiovascular diseases are the leading causes of morbidity and mortality. Cardiovascular diseases can be prevented and controlled by modifying lifestyle risk behaviors. In this qualitative study, we investigate ways to increase participation in physical activity, and to promote a healthy diet, and nonsmoking behavior in Qatari women. Individual in-depth interviews were conducted with...

Due to the impact of global climate change, the urban flooding in Taiwan occurs frequently, causes serious damage. Understanding the disaster perception is desirable in order to implement the urban disaster management. This paper aims to investigate the flood perception of residents along Erren River Bank in Tainan, Taiwan by using questionnaire survey method. The findings show that the residen...

The design of laboratory archives depends to a large extent on frequency and type of access required. This article reports a study in which all requests for laboratory archival data were tabulated carefully. Such requests are infrequent and usually involve specific test results. An inexpensive, efficient, and convenient method of storing such data is described, employing a laboratory computer a...

Simulation of the marine environment has become an important tool across a wide range of human activities, with applications in coastal engineering, offshore industries, fisheries management, marine pollution monitoring, weather forecasting and climate research to name but a few. Hydrodynamic models have been under development for many years and have reached a high level of sophistication. Howe...

Human-induced stresses of overfishing, eutrophication, climate change, translocation and habitat modification appear to be promoting jellyfish (pelagic cnidarian and ctenophore) blooms to the detriment of other marine organisms. Mounting evidence suggests that the structure of pelagic ecosystems can change rapidly from one that is dominated by fish (that keep jellyfish in check through competit...

Land cover change in watersheds affects the supply of a number of ecosystem services, including water supply, the production of timber and nontimber forest products, the provision of habitat for forest species, and climate regulation through carbon sequestration. The Panama Canal watershed is currently being reforested to protect the dry-season flows needed for Canal operations. Whether refores...

Sets of desirable gambles constitute a quite general type of uncertainty model with an interesting geometrical interpretation. We study exchangeability assessments for such models, and prove a counterpart of de Finetti’s finite representation theorem. We show that this representation theorem has a very nice geometrical interpretation. We also lay bare the relationships between the representatio...

Americans find certain issues in public policy much easier to ignore than to confront. The necessity of rationing health care is one such issue. Because Americans believe that access to health care is a basic right,1 we, as a society, have avoided facing the hard fact that it is not feasible to provide, on demand, all needed medical procedures to every individual who could potentially benefit f...

operations are de ned as upgraded versions of previous ones. This ispossible only because of the systematic use of speci cations, since a correctreuse of previous operations can be based on explicit reasoning. Moreover, themathematical framework used by this version is still weaker than the previousones, since there is no abstract xpoint at all, even in theory. Finally, this ana...

Motivational attitudes play an important role in investigations into intelligent agents. One of the key problems of representing and reasoning about motivational attitudes is which propositions are the desirable ones. The answer based on classical logic is that the propositions that logically imply the goal are desirable and the others are not. We argue that this criterion is inadequate for the...
