This paper summarizes the results of a panel on how database content is covered in current university programs, with reference to the IS2002 model curriculum. Panelists included information systems (IS) faculty members who are actively involved in determining the coverage of database content at their institutions and in establishing academy-wide database content and technology resources. Topics...

Global Positioning System (GPS) measurements in China indicate that crustal shortening accommodates most of India's penetration into Eurasia. Deformation within the Tibetan Plateau and its margins, the Himalaya, the Altyn Tagh, and the Qilian Shan, absorbs more than 90% of the relative motion between the Indian and Eurasian plates. Internal shortening of the Tibetan plateau itself accounts for ...

BACKGROUND Twitter provides various types of location data, including exact Global Positioning System (GPS) coordinates, which could be used for infoveillance and infodemiology (ie, the study and monitoring of online health information), health communication, and interventions. Despite its potential, Twitter location information is not well understood or well documented, limiting its public hea...

Information technology (IT) innovations have been vital to the success of organizations seeking to improve efficiency and productivity. IT’s global diffusion has however raised serious questions about its neutral application across cultures and contexts. This paper synthesizes a sample of the literature to conceptualize the key cultural challenges in IS innovation as, differentiation, externali...

Precise navigation is a vital need for many modern vehicular applications. The global positioning system (GPS) cannot provide continuous navigation information in urban areas. The widely used inertial navigation system (INS) can provide full vehicle state at high rates. However, the accuracy diverges quickly in low cost microelectromechanical systems (MEMS) based INS due to bias, drift, noise, ...

A hallmark of the emerging `information age' is the dramatic rise in expenditures by modern business enterprises on information technologies (IT). On account of these investments, senior managers anticipate gains in productivity, which are commensurate with the cost of modern IT and Information Systems. While the evolving capabilities of emerging IT are evident, the association between technolo...

Purpose: To date, no studies utilizing global positioning system (GPS) technologies to measure mobility and environmental exposures have been conducted among a sample of transgender women despite the potential salient role neighborhood contexts may play in the health of this population. As such, the purpose of this study was to assess the acceptability and feasibility of a weeklong GPS protocol...

Global positioning system (GPS) technology has improved the speed, accuracy, and ease of time-motion analyses of field sport athletes. The large volume of numerical data generated by GPS technology is usually summarized by reporting the distance traveled and time spent in various locomotor categories (e.g., walking, jogging, and running). There are a variety of definitions used in the literatur...

The first decade of the century witnessed a proliferation of devices with sensing and communication capabilities in the possession of the average individual. Examples range from camera phones and wireless global positioning system units to sensor-equipped, networked fitness devices and entertainment platforms (such as Wii). Social networking platforms emerged, such as Twitter, that allow sharin...

Aim: The use of external and internal load is an important aspect of monitoring systems in team sport. The aim of this study was to validate a novel measure of training load by quantifying the training-performance relationship of elite Australian footballers. Methods: The primary training measure of each of 36 players was weekly load derived from a weighted combination of Global Positioning Sys...
