Empirical Research of Decision-making Effectiveness When Using Differing Presentation Formats Under Varying Decision Tasks

Empirical Research of Decision-making Effectiveness When Using Differing Presentation Formats Under Varying Decision Tasks

Date: December 1988
Creator: Hard, Nancy J. (Nancy Jean)
Description: The purpose of this research was to determine if presentation format, given a particular task to be performed, would affect the decision-making process of financial decision makers. The problem motivating this study is the potential for managers to make inefficient decisions when they use reports which are presented inappropriately for a given task.

A Study of Differences Perceived by Information Systems Professionals in the Systems Development Job Environment Due to the Use of ICASE Technology

A Study of Differences Perceived by Information Systems Professionals in the Systems Development Job Environment Due to the Use of ICASE Technology

Date: August 1997
Creator: Troboy, Lori Kim
Description: Information systems professionals now face the automation of their own work in integrated computer aided software engineering. Organizations need to achieve all the leverage possible from costly IT implementations to enhance competitiveness, profitability, and survival in a rapidly changing environment. ICASE technology is a part of the infrastructure necessary to meet this challenge but appears to present significant difficulties in implementation.

Organizational Considerations for and Individual Perceptions of Web-Based Intranet Systems

Organizational Considerations for and Individual Perceptions of Web-Based Intranet Systems

Date: May 1999
Creator: Myerscough, Mark Alan
Description: Utilization of World Wide Web style Web-Based Intranet Systems (W-BIS) is a rapidly expanding information delivery technique in many organizations. Published reports concerning these systems have cited return on investment values exceeding 1300% and direct payback time periods as low as six to twelve weeks. While these systems have been widely implemented, little theoretically grounded research has been conducted in relation to users' acceptance, utilization or the perceived quality of these systems. The study employed a two-site investigation of corporate Web-Based Intranet Systems, with surveys distributed via the traditional mail system. The complete survey instrument distributed to employees included the ServQual/ServPerf, User Information Satisfaction, Ease of Use/Usefulness, and Computer Playfulness instruments. In addition to these previously developed instruments, the survey instrument for this study included measures of Web-Based Intranet Systems utilization and usefulness along with respondent demographics and subordinate-reported managerial commitment. This study investigated the reliability and validity of the ServQual/ServPerf instrument in an information systems service environment. The same analysis was conducted of the more generally accepted User Information Satisfaction instrument.

Classification by Neural Network and Statistical Models in Tandem: Does Integration Enhance Performance?

Classification by Neural Network and Statistical Models in Tandem: Does Integration Enhance Performance?

Date: December 1998
Creator: Mitchell, David
Description: The major purposes of the current research are twofold. The first purpose is to present a composite approach to the general classification problem by using outputs from various parametric statistical procedures and neural networks. The second purpose is to compare several parametric and neural network models on a transportation planning related classification problem and five simulated classification problems.

An Experimental Investigation of Information Systems Project Escalation: An Examination of Contributory Factors in a Business Environment

An Experimental Investigation of Information Systems Project Escalation: An Examination of Contributory Factors in a Business Environment

Date: August 1997
Creator: Huff, Richard A. (Richard Allen)
Description: The purpose of this research is to continue examining the project management process. The management of projects is complicated. It is the complexity of the process that makes a project so difficult to control. This research examines the effect of particular facets of the project manager's skill set and operating environment on management decisions.

An Empirical Investigation of Detail Design Tools and Cognitive Style of Software Developers

An Empirical Investigation of Detail Design Tools and Cognitive Style of Software Developers

Date: May 1992
Creator: Flores-Rosales, Oscar
Description: The purpose of this study is to identify what detail design tools are more productive for the different types of professional software developers. By establishing a match between the detail design tool and the cognitive style of the professional programmer, the end product (Information Systems) should be of a higher quality. Two laboratory experiments were conducted. The first experiment was with professional Software Developers; the second one was with students. The dependant variables considered in this study were the number of semantic errors and the time required to complete a design task for conditional logic. The independent variables were the cognitive style of the subject, the complexity of the task, and the detail design tools. Decision trees, flowcharts and pseudocode were used as detailed design tools. Field dependence was the only dimension of cognitive style that was tested.

Interactions of Presentation Formats and Decision-Maker Characteristics upon Multiple Decision-Making Tasks: an Experiment Using Multiple Cognitive Assessments

Interactions of Presentation Formats and Decision-Maker Characteristics upon Multiple Decision-Making Tasks: an Experiment Using Multiple Cognitive Assessments

Date: December 1994
Creator: Henson, Kerry L. (Kerry Lynn)
Description: Information systems research tends to ignore individual differences in users. This laboratory experiment sought to illuminate contributions of decision-makers' cognitive processes to decision outcome as reflected in four hypothesis sets: the impact of imagery preference and presentation format upon (HI) recall accuracy and upon hemispheric activation during (H2) encoding and (H3) recall, and (H4) to examine the relationship between hemispheric activation differences and accuracy differences. Point-value (specific values) and intraset-pattern (relationships between values) recall were considered. Thirty MBA students, grouped by imagery preference (cognitive style) as favoring verbal (textual) or visual (graphical) information presentation, performed computer-based recall tasks using tabular and graphical formats in a repeated measures design. Hemispheric activation (cognitive process) was assessed using ratios of EEG activity in six frequency bands captured from six pairs of homologous electrode sites during encoding and recall.
