Th e airport catchment area is the geographic from which an can reasonably expect to draw commercial air service passengers. purpose of this interdisciplinary research estimate areas using a spatial analysis method for informed management. In order ensure comprehensiveness and reliability research, we chose analyze five airports different sizes in locations United States. The Huff model, usuall...

Huff, F.J., S.F. Mickel, S. Corkin, and J.H. Growdon: Cognitive functions affected by scopolamine in Alzheimer’s disease and normal aging. Drug Dev. Res. 12:271-278, 1988. We gave scopolamine to patients with Alzheimer’s disease (AD) and age-matched control subjects in order to identify which cognitive functions are affected by blocking muscarinic receptors for acetylcholine (ACh). Both subject...

Although ethical decision making is a key concern of organizations, the impacts of IT on ethical discourse is an underexplored topic. The laboratory experiment reported in this paper examines the impacts of the use of group support systems (GSSs) on moral discourse. Drawing upon Toulmin’s (1958) model of argumentation and Kohlberg’s (1976) framework of stages of moral reasoning, we used the tec...

Isogenies are the morphisms between elliptic curves, and are accordingly a topic of interest in the subject. As such, they have been wellstudied, and have been used in several cryptographic applications. Vélu’s formulas show how to explicitly evaluate an isogeny, given a specification of the kernel as a list of points. However, Vélu’s formulas only work for elliptic curves specified by a Weiers...

The western black-legged tick, Ixodes pacificus, was collected from Huff Canyon in the Sutter Buttes in north central California, Sutter County. The Sutter Buttes are within the Sacramento Valley and outside the normal distribution of I. pacificus in California. Adult I. pacificus were collected via flagging as they quested along deer trails; subadult life stages were collected from three speci...

The spatial distribution pattern of hospitals in Wuhan indicates a core in the central urban areas and a sparse distribution in the suburbs, particularly at the center of suburbs. This study aims to improve the gravity and Huff models to analyze healthcare accessibility and resources. Results indicate that healthcare accessibility in central urban areas is better than in the suburbs, where it i...

Business strategy represents the choice of how to compete for competitive advantage (Porter, 1980, Porter, 1985). And Strategic Information Systems (SIS) shape (Rackoff et al., 1985, Wiseman, 1985) and enable (Bensaou and Venkatraman, 1995) that business strategy. SIS has been the focus of a large body of research and anecdotal descriptions (Chan and Huff, 1992, Porter and Millar, 1985, Wiseman...
