Which characteristics of managers ’ information search behavior distinguish successful from less successful use of (executive) information systems. 3 This article addresses this question by employing a new process-tracing approach in an exploratory laboratory study with fifty managers as participants. Building upon and extending existing theoretical models, three main factors are identified rel...

have aroused great interest in fi elds as diverse as biology, psychology, medicine, economics, mathematics, statistics and computer science. The main reason underlying this interest lies in the fact that ANN are general, fl exible, nonlinear tools capable of approximating any sort of arbitrary function (Hornik, Stinchcombe, & White, 1989). Due to their fl exibility as function approximators, AN...

increasing in magnitude and frequency around the globe, causing extensive economic and Blooms of toxic algae are environmental impacts. On the west coast of Florida, blooms of the toxic dinoflagellate Karenia brevis (Davis) have been documented annually for the last 30 years causing respiratory irritation in humans, fish kills, and toxin bioaccumulation in shellfish beds. As a result, methods n...

Thirty years ago, Courant gave a remarkable lecture to this Society. My talk today is more or less a progress report on an idea which he described near the end of that lecture. There are a lot of people in this city, and a few in this room, who worked very closely with Courant—but the idea I am talking about came to fruition in a different and more unexpected way. To begin with, his idea was fo...

Sea turtles inhabiting coastal environments routinely encounter anthropogenic hazards, including fisheries, vessel traffic, pollution, dredging, and drilling. To support mitigation of potential threats, it is important to understand fine-scale sea turtle behaviors in a variety of habitats. Recent advancements in autonomous underwater vehicles (AUVs) now make it possible to directly observe and ...

The environment in which a DSS is developed can have a significant impact on the development and satisfaction provided by the DSS. A questionnaire was sent to nonacademic TIMS members in an attemmpt to identify specific DSS environments, the capabilities provided by these DSS, and environmental factors that significantly influenced the DSS environment. This paper presents the results of this in...

Several attempts have been made in the past at imaging the fetus at 3T as part of the continuous search for increased image signal and better anatomic delineation of the developing fetus. Until now, imaging of the fetus at 3T has been disappointing, with numerous artifacts impeding image analysis. Improved technology now allows imaging of the fetus at greater magnetic strength, while still enco...

Autonomous underwater ve hicles (AUV’s) are increasingly used to collect physical, chemical, and biological information in the marine environment. Recent efforts include merging AUV technology with acoustic telemetry to provide information on the distribution and movements of marine fi sh. We compared surface vessel and AUV tracking capabilities under rigorous conditions in coastal waters near ...
