The Effectiveness Of Expert Support Technology For Decision Making: Individuals Versus Small Groups, Fiona Fui-Hoon Nah, Jiye Mao, Izak Benbasat

Research Collection School Of Computing and Information Systems

Expert support systems (ESSs) are increasingly used in organizations to support individuals and groups in decision making. Although ESSs have been shown to enhance the decision-making capabilities of individuals, their benefits in supporting group decision making are less clear. To the best of our knowledge, no empirical research has evaluated the effectiveness of the technology in the group setting or compared its usefulness for supporting individual versus group decision making. The results of this research show that ESSs benefit decision making of both individuals and groups and novices are able to gain more from ESSs than experts. The findings also …

An Examination Of The Self-Perceptions Of The Physical Environment And Psychological Health Of Latina Women Living In The St. Columbia Neighborhood Of Newark, New Jersey, Veronica Maria Maya

Theses

A correlation between perceptions of environmental quality and psychological health has been established in a sample of Latina women. Three psychological scales exist to measure psychological constructs such as learned helplessness, hopelessness, and selfesteem. These three scales have been used in conjunction with an environmental survey designed to capture the perceptions of the sample to their physical environment.

The mean of scores for each psychological construct in the Latina sample were compared to the mean of scores for these constructs in independent samples of oncology, hemodialysis, and spinal cord injured patients being treated for depression. This comparison yields the following …

Collaborative Agent Design (CAD) Research Center

The rationale of the Workshop rests on some very simple observations. It is well known that every situation encountered by individuals and organizations demands an appropriate response. The choice of such a response from among a multitude of options is the decision-making process. Simple situations that give rise to a small number of options allow the decision maker to decide on a course of action without great effort. This state of affairs changes dramatically when the situations are complex and involve a large number of factors. In this case, an extensive field of options is engendered that makes it impossible …

Collaborative Decision-Support And The Human-Machine Relationship, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Human beings are inquisitive creatures who seek explanations for all that they observe and experience in their living environment. While this quest for understanding is central to our success in adapting to a changing environment, it is also a major cause of our willingness to accept partial understandings and superficial explanations when the degree of complexity of the problem situation confounds our current cognitive capabilities. In other words, a superficial or partial explanation is considered better than no explanation at all. As flawed as this approach may be, it has helped us to solve difficult problems in stages. By first …

The Dynamics Of Cyberspace: Examining And Modelling Online Social Structure, Brian S. Butler '89

Doctoral Dissertations

It has been proposed that online social structures represent new forms of organizing which are fundamentally different from traditional social structures. However, while there is a growing body of empirical research that considers behavioral aspects of online activity, research on online social structure structural remains largely anecdotal. This work consists of three papers that combine previous studies of traditional social structures, empirical analysis of longitudinal data from a sample of Internet listservs, and computational modeling to examine the dynamics of social structure development in networked environments.

The first paper (Title: When is a Group not a Group: An Empirical Examination …

Information Modeling And Method Engineering: A Psychological Perspective, Keng Siau

Research Collection School Of Computing and Information Systems

Information modeling is the cornerstone of information systems analysis and design. Information models, the products of information modeling, not only provide the abstractions required to facilitate communication between the analysts and end users, but they also provide a formal basis for developing tools and techniques used in information systems development. The process of designing, constructing, and adapting information modeling methods for information systems development is known as method engineering. Despite the pivotal role of modeling methods in successful information systems development, most modeling methods are designed based on common sense and intuition of the method designers with little or no …

Judicial Politics, Death Penalty Appeals, And Case Selection: An Empirical Study, John H. Blume, Theodore Eisenberg

Cornell Law Faculty Publications

Several studies try to explain case outcomes based on the politics of judicial selection methods. Scholars usually hypothesize that judges selected by partisan popular elections are subject to greater political pressure in deciding cases than are other judges. No class of cases seems more amenable to such analysis than death penalty cases. No study, however, accounts both for judicial politics and case selection, the process through which cases are selected for death penalty litigation. Yet, the case selection process cannot be ignored because it yields a set of cases for adjudication that is far from a random selection of cases. …

Texture Analysis Of Sar Sea Ice Imagery Using Gray Level Co-Occurrence Matrices, Leen-Kiat Soh, Costas Tsatsoulis

School of Computing: Faculty Publications

This paper presents a preliminary study for mapping sea ice patterns (texture) with 100-m ERS-1 synthetic aperture radar (SAR) imagery. We used gray-level co-occurrence matrices (GLCM) to quantitatively evaluate textural parameters and representations and to determine which parameter values and representations are best for mapping sea ice texture. We conducted experiments on the quantization levels of the image and the displacement and orientation values of the GLCM by examining the effects textural descriptors such as entropy have in the representation of different sea ice textures. We showed that a complete gray-level representation of the image is not necessary for texture …

Segmentation Of Satellite Imagery Of Natural Scenes Using Data Mining, Leen-Kiat Soh, Costas Tsatsoulis

School of Computing: Faculty Publications

In this paper, we describe a segmentation technique that integrates traditional image processing algorithms with techniques adapted from knowledge discovery in databases (KDD) and data mining to analyze and segment unstructured satellite images of natural scenes. We have divided our segmentation task into three major steps. First, an initial segmentation is achieved using dynamic local thresholding, producing a set of regions. Then, spectral, spatial, and textural features for each region are generated from the thresholded image. Finally, given these features as attributes, an unsupervised machine learning methodology called conceptual clustering is used to cluster the regions found in the image …

The Practitioner From Within: Revisiting The Virtues, Frances Grodzinsky

School of Computer Science & Engineering Faculty Publications

Traditionally the study of computer ethics involves taking students who are not philosophically trained, exposing them to action-guiding theories, presenting them with the codes of ethics of several companies and professional organizations and asking them to make ethical decisions in scenario-based cases. This approach is deliberately action-based and focuses on doing. "What would you do?" is the traditional question we ask our students. While this pedagogical methodology forces them to examine situations and argue from a particular point of view, it does little to influence their character. They see the utilitarian or deontologist as someone other than themselves. There seems …

Some Studies On Shape Of Dot Patterns., Anirban Ray Chaudhuri Dr.

Doctoral Theses

The important visual characteristics of an object are shape, size, color, brightness, contrast and texture. Of them, shape is a multidimensional concept that is difficult to define. It takes different meanings in different contexts. We try to explain it in terms of their attributes like elongation, roundness, and symmetry: although these terms do not capture the complete notion of shape.Perhaps Gestalt theory Koffka 351 is the first attempt to study the principles of visual perception in a systematic manner. The central concept of this theory is Gestalt' which means form or configuration. In this theory form is examined from physical. …

Measurement Of Influence Of The Teacher’S Personality On Students In The Classroom, Shlomo S. Sawilowsky

Theoretical and Behavioral Foundations of Education Faculty Publications

The focus of this research is the assessment of pedagogical interaction as a dimension of the learning environment through the personal representation of a teacher in the student’s personality, and the assessment of the nature and extent to which teachers are involved in changes of interpersonal dimensions of their student’s personality. This was examined by the assessment of the shift in egograms of a teacher’s students, as measured by the Interpersonal Check List (ICL). A 2 x 9 doubly multivariate repeated measures analysis of variance was conducted on the adult, parent, and child ego states as self-assessed by 187 students …

Hands-On Computer Use In Science Classrooms: The Skeptics Are Still Waiting, Alan Runge, Amy N. Spiegel, Lisa M. Pytlikzillig, Steven Dunbar, Robert Fuller, Glenn Sowell, David W. Brooks

Robert G. Fuller Publications

Frank Collea was a friend of Robert Fuller and David Brooks, and a mentor to Brooks. We miss him for his energy, his enthusiasm for teaching science, and his perception about how to improve science education. Frank Collea was not a big fan of using computers in instruction. Frank was neither an advocate of using computers to deliver instruction, nor an advocate of teaching their use as professional tools. Indeed, he thought that most of those of us who advocate computer use make assertions that are unwarranted. A decade ago, desktop computers were beginning to appear in colleges and universities …

The Deconstruction Of Mathematics: A Criticism Of Reuben Hersh's What Is Mathematics, Really? And The Humanist Philosophy Of Mathematics, David J. Stucki

Mathematics Faculty Scholarship

Mathematics, as an academic discipline, has stood for many years as the last bastion against a growing tide of intellectual relativism that has become all but ubiquitous. More recently, however, efforts have been made to "humanize" mathematics by advocating a social-constructivist approach to the philosophy of mathematics, both in practice and education. This paper is intended to serve as a critical response to one advocate of this approach, Reuben Hersh (What Is Mathematics, Really?, 1997), and in the process a defense of Platonism.

The Effect Of Mechanical Noise And Natural Sound On Visitor Experiences In Units Of The National Park System, Dr. James Gramann, National Park Service, U.S. Department Of The Interior

All U.S. Government Documents (Utah Regional Depository)

This paper reviews research on the effects of mechanical noise and natural sound on visitor experiences in national parks. Three approaches to studying noise impacts are described. Most noise research to date has addressed the impact of air-tour overflights on visitor experiences. these impacts are localized with significant percentages of visitors in some parks reporting interference with natural sounds from aircraft noise. Research also shows that unthreatening natural environments can have significant stress-reducing effects for many people. However, it is unclear if these effects are due to hearing the sounds of nature or to a combination of hearing and seeing …
