Impact of Geospatial Reasoning Ability and Perceived Task-Technology Fit on Decision-Performance: The Moderating Role of Task Characteristics

Consumer, business and governmental entities increasingly rely on spatial decision support systems (SDSS) for decision-making involving geospatial data. Understanding user- and task-characteristics that impact decision performance will allow developers of such systems to maximize geospatial decision-making performance. Furthermore, scholars will benefit from a more comprehensive understanding of what specific characteristics influence decision-making as such knowledge can guide future research in the decision sciences domain. This paper provides a synthesis of geospatial reasoning ability, task-complexity, geovisualization and decision-performance research. A two-factor experiment designed to measure the impact of geospatial reasoning ability on decision-performance is performed. Two treatments, problem-complexity and map-complexity, are investigated for their moderating role on decision-performance. A partial least squares analysis is performed to assess the experiment results. Cognitive Fit Theory is used as the theoretical framework of this study and is extended, along with research in decision-performance and geospatial reasoning ability

Unpleasant Updates: Discussing Negative Project Performance with Executives

Project managers often have early indications that a project is performing poorly and potentially headed for failure. In such cases, reporting these warnings could prompt executives to provide essential support to mitigate and even prevent problems. However, project managers are frequently reluctant to share such information with executives. This research-in-progress aims to develop a model establishing antecedents that drive accurate status reporting between project managers and executives as well as identifying moderating variables impacting such reporting. The theory of planned behavior and information systems (IS) whistleblowing theory provide the theoretical lenses facilitating the identification of probable antecedents to such reporting intentions. A theoretical model including propositions has been developed

Survey of Desktop Virtualization in Higher Education: An Energy- and Cost-Savings Perspective

Benefits of utilizing desktop virtualization technology in higher education environments include the ability to deploy numerous applications, which may conflict on a traditional desktop, into a single image. Additionally, the utilization of thin-clients could produce substantial energy savings and reduce physical desktop replacement costs. Finally, virtualized desktops can be delivered to numerous non-enterprise devices, particularly student’s personal laptops or dorm-room computers. While there appear to be numerous benefits to desktop virtualization, there are many barriers to adoption. This paper outlines the substantial energy- and cost-savings provided through desktop virtualization in higher education. A literature review of relevant works and findings of a university implementation workgroup are presented using a case-study approach

Utilizing Volunteered Geographic Information to Develop a Real-Time Disaster Mapping Tool: A Prototype and Research Framework

The global proliferation of personal mobile devices has provided the capability of electronic data collection to billions of people. Furthermore, recent innovations in technologies and implementation methodologies have allowed groups of people to collect and analyze large quantities of data. Examples of such systems include Wikipedia, a community-sourced digital encyclopedia, and Yelp, a directory and review tool of local businesses. The occurrence of important events or the establishment of new restaurants has motivated individuals to provide timely and accurate contributions to Wikipedia or Yelp, respectively. Considering the benefits of widespread data collection capabilities and the motivations to contribute to public knowledge, this design-science paper proposes and prototypes components of a publically driven, real-time disaster-response mapping system

The Effects of Geospatial Website Attributes on eImage: An Exploratory Study

This research-in-progress analyzes the impacts of geospatial website attributes on eImage, or the online image of an organization. Specifically, geospatial attributes on websites of service-oriented businesses that must convince consumers to visit their physical locations are addressed. Limited existing research regarding geospatial website attributes provided the motivation to conduct this study. Additionally, the moderating impact of geospatial reasoning ability on eImage is explored. The results of this study will further electronic commerce and human-computer interaction research, expand the understanding of website attributes and their effects on eImage, as well as provide practical guidance for web designers
