From Guts To God: Credulity, Postmodernism, And Contemporary Physics, Michael Hardin
From Guts To God: Credulity, Postmodernism, And Contemporary Physics, Michael Hardin
Reconstruction: Studies in Contemporary Culture
[Editors' Introduction]
In an attempt to remove one of the major misunderstandings made by individuals in the humanities about contemporary physics, the issue of incredulity, this essay examines Lyotard's The Postmodern Condition: A Report on Knowledge against contemporary and twentieth-century theories and discoveries in physics. One of the best arguments against incredulity is the frequent use of god as metaphor within physics. In Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science, Alan Sokal and Jean Bricmont, two physicists, argue that the use of metaphor is one of the characteristics of postmodern science; this essay concludes with a discussion of those elements …

Of Parts And Wholes: Self-Similarity And Synecdoche In Science, Culture And Literature, Dirk Vanderbeke
Reconstruction: Studies in Contemporary Culture
[Editors' Introduction]
The discussion here centers on how self-similarity, or parts resembling a whole, has been a recurring aspect in the most diverse fields of human thinking from antiquity to the present. Primary examples are drawn from physics, biology, cybernetics, alchemy, philosophy, myth and, of course, language and literature. The author argues that self-similar patterns are one of the persistent ways in which the human mind structures its experience and knowledge of the world, and then examines some of the questions that arise when an almost ubiquitous concept, structure or linguistic and literary phenomenon resurfaces in a new guise in …

Are Use Case And Class Diagrams Complementary In Requirements Analysis? An Experimental Study On Use Case And Class Diagrams In Uml, Keng Siau, Lihyunn Lee
Are Use Case And Class Diagrams Complementary In Requirements Analysis? An Experimental Study On Use Case And Class Diagrams In Uml, Keng Siau, Lihyunn Lee
Research Collection School Of Computing and Information Systems
Despite the status of united modeling language (UML) as the de facto standard for object oriented modeling, it has received controversial reviews. The most controversial diagram in UML is the use case diagram. Some practitioners claim that use case diagrams are not valuable in requirements analysis and some have even argued that use case diagrams should not be part of UML. This research examined the values of use case diagram in interpreting requirements when use case diagrams are used in conjunction with class diagrams. In other words, the study investigated the possible synergetic values and relationships between the use case …
The Role Of Reactivity In Multiagent Learning, Bikramjit Banerjee, Jing Peng
The Role Of Reactivity In Multiagent Learning, Bikramjit Banerjee, Jing Peng
Department of Computer Science Faculty Scholarship and Creative Works
In this paper we take a closer look at a recently proposed classification scheme for multiagent learning algorithms. Based on this scheme an exploitation mechanism (we call it the Exploiter) was developed that could beat various Policy Hill Climbers (PHC) and other fair opponents in some repeated matrix games. We show on the contrary that some fair opponents may actually beat the Exploiter in repeated games. This clearly indicates a deficiency in the original classification scheme which we address. Specifically, we introduce a new measure called Reactivity that measures how fast a learner can adapt to an unexpected hypothetical change …
A Marginal Model Approach For Analysis Of Multi-Reader Multi-Test Receiver Operating Characteristic (Roc) Data, Xiao Song, Xiao-Hua Zhou
A Marginal Model Approach For Analysis Of Multi-Reader Multi-Test Receiver Operating Characteristic (Roc) Data, Xiao Song, Xiao-Hua Zhou
UW Biostatistics Working Paper Series
The receiver operating characteristic (ROC) curve is a popular tool to characterize the capabilities of diagnostic tests with continuous or ordinal responses. One common design for assessing the accuracy of diagnostic tests is to have each patient examined by multiple readers with multiple tests; this design is most commonly used in a radiology setting, where the results of diagnostic tests depend on a radiologist's subjective interpretation. The most widely used approach for analyzing data from such a study is the Dorfman-Berbaum-Metz (DBM) method (Dorfman, Berbaum and Metz, 1992) which utilizes a standard analysis of variance (ANOVA) model for the jackknife …
Proceedings Of The 2004 Onr Decision-Support Workshop Series: Interoperability, Collaborative Agent Design Research Center
Proceedings Of The 2004 Onr Decision-Support Workshop Series: Interoperability, Collaborative Agent Design Research Center
Collaborative Agent Design (CAD) Research Center
In August of 1998 the Collaborative Agent Design Research Center (CADRC) of the California Polytechnic State University in San Luis Obispo (Cal Poly), approached Dr. Phillip Abraham of the Office of Naval Research (ONR) with the proposal for an annual workshop focusing on emerging concepts in decision-support systems for military applications. The proposal was considered timely by the ONR Logistics Program Office for at least two reasons. First, rapid advances in information systems technology over the past decade had produced distributed collaborative computer-assistance capabilities with profound potential for providing meaningful support to military decision makers. Indeed, some systems based on …
Utilizing Learning Styles For Interactive Tutorials, Magnus Aase, Franz J. Kurfess
Utilizing Learning Styles For Interactive Tutorials, Magnus Aase, Franz J. Kurfess
Computer Science and Software Engineering
Developing successful Web-based learning environments has shown to be a challenging and difficult endeavor [7][11] that requires knowledge from multiple domains like pedagogy, psychology, knowledge engineering, software engineering, and Web technologies. Their lack of individual preferred ways of instruction is a challenge we address in this paper. We introduce a Web-based learning environment that teaches concepts from Artificial Intelligence to college students. This environment is intended to be used as a complementary tool for the standard lectures. By adapting the instruction and learning material to the individual student’s learning style the tutorial gives the student a personal learning experience and …

Pyro: A Python-Based Versatile Programming Environment For Teaching Robotics, Doug Blank, Deepak Kumar, Lisa Meeden, Holly Yanco
Computer Science Faculty Research and Scholarship
In this paper we describe a programming framework called Pyro which provides a set of abstractions that allows students to write platformindependent robot programs. This project is unique because of its focus on the pedagogical implications of teaching mobile robotics via a topdown approach. We describe the background of the project, novel abstractions created, its library of objects, and the many learning modules that have been created from which curricula for different types of courses can be drawn. Finally, we explore Pyro from the students' perspective in a case study.

Condylar Remodeling After Distraction Osteogenesis And Bilateral Sagittal Split Osteotomy, Robert Barker Hoffman
Loma Linda University Electronic Theses, Dissertations & Projects
The present pilot study is a histological evaluation of mandibular condyles taken from minipigs that underwent either traditional mandibular advancement (bilateral sagittal split osteotomy), or a distraction osteogenesis procedure to advance the mandible. One pig received a bilateral sagittal split osteotomy with an immediate mandibular advancement of 14 mm, while another pig underwent distraction osteogenesis consisting of a gradual advancement of 2 mm per day to advance the mandible the same distance. The control animal received no surgery.
In the present study, the mandibular condyles of the three pigs (2 control, 2 bilateral sagittal split osteotomy, and 2 distraction osteogenesis) …

Research Collection School Of Computing and Information Systems
Mobile commerce represents a significant development in e-commerce, offering accessibility, ubiquity, mobility, and localisation to users. Despite the potential of mobile commerce, trust is a major obstacle in its adoption and development. Many consumers feel uncomfortable with the idea of conducting commerce over wireless, hand-held devices. The focus of this research is to understand trust in mobile commerce and to identify factors that are important for trust development. The research builds on Siau and Shen's framework which depicts two key factors influencing trust in mobile commerce. This research not only validates and expands on the existing framework, but also provides …
Building A Model Of Campus Diversity: An Organization-As-The-Individual Based Approach, Ian Spencer Ray
Building A Model Of Campus Diversity: An Organization-As-The-Individual Based Approach, Ian Spencer Ray
Electronic Theses and Dissertations
Diversity is a vital concept when engaging with modern social science research and among higher education practitioners. Despite the pervasive discourse surrounding diversity, equity, and inclusion (DEI) initiatives, quantification of diversity remains a challenge across the social sciences. This study proposes a new conceptual framework, applies the framework to the quantification of diversity and measurement of its impacts. Further, this study demonstrates the robustness of the new conceptual framework alongside the positive impacts of diversity on institutional outcomes.
The Organization-As-The-Individual (OATI) framework arises from an integration of the social and biological sciences. The framework argues that humans, as biological organisms, …

Examination Of Technologies For Student-Generated Work In A Peer-Led, Peer-Review Instructional Environment, Brian P. Coppola, Alan L. Kiste
Chemistry and Biochemistry
There is a growing literature demonstrating the effectiveness of using computer environments to assist students’ in visualizing science and mathematics concepts. However, with many of these computerized learning environments, students do not have the option of manipulating the environment. Instead, they are presented with pre-made visualizations. Enabling students to display their understanding through multiple representational forms is more interesting. In our peer-led, peer-review environment, students generate a complex, literature-based, multimedia text on which their final examination is based. However, there are great time and personnel costs in this design. Collaborating with SRI Inc., we are addressing these demands via the …

Center for Coastal and Ocean Mapping
Empirical investigations were carried out in a research project for the German Federal Ministry of Transport, Building, and Housing to evaluate the presentation of AIS target information on ECDIS. The investigations were performed at three international simulation centres. The features, colour and fillingjsize of AIS symbols, as well as the influence of the ECDIS display category on the detection of AIS targets were the main issues of the investigations. Results show that blue (5-52 colour token RE5BL) is the most suitable colour of the tested colours for the presentation of AIS targets under all ambient light conditions on the tested …

Instructing Teachers Of Children With Disabilities Within The Church Of Jesus Christ Of Latter-Day Saints, Katie E. Sampson
Instructing Teachers Of Children With Disabilities Within The Church Of Jesus Christ Of Latter-Day Saints, Katie E. Sampson
Theses and Dissertations
This study investigates benefits of in-service training on LDS primary teachers' ability to state an objective, obtain and keep attention, use wait time, incorporate active participation, teach to the multiple intelligences, and employ positive behavior management techniques. Two groups of 30 viewed either a video-tape or read a handout. Pre and post surveys were used to determine mean gain.
Using an ANCOVA, comparisons were made of overall mean gain for each group. Results showed participants made a gain of approximately 1/2 point per question on a 4-point scale on the video and the handout (video gain = .6032 p<.01; handout gain = .6264 p<.01). The results of this study support the hypothesis that teachers receiving one in-service will increase their perception of their ability to teach students with special needs.

Investigating Deception In Cyberspace, Holtjona Galanxhi, Fiona Fui-Hoon Nah
Research Collection School Of Computing and Information Systems
The use of anthropomorphic avatars provides Internet users the opportunity and freedom to present their desired identity. As cyberspace becomes a heaven for deceptive behavior, human-computer interaction research will need to be carried out to study and understand these deceptive behaviors. The objective of this research is to investigate the behavior of deceivers and truthtellers in the cyberspace environment and to examine how their intention to deceive may influence the choice of their avatars. The effect of using avatars to support communication will also be studied. This research provides insights on communication and trust issues in avatar environments.
Theoretical And Practical Complexity Of Uml, J. Erickson, Keng Siau
Theoretical And Practical Complexity Of Uml, J. Erickson, Keng Siau
Research Collection School Of Computing and Information Systems
Systems have become increasingly complex, and as a result development methods have become more complex as well. The unified modeling language (UML) has been criticized for the often cited and sometimes over-whelming complexity it presents to its users, and those seeking to learn to use it. Using Rossi and Brinkkemper’s (1996) complexity metrics, Siau and Cao (2001) completed a complexity analysis of UML and 36 other modeling techniques, finding that UML is indeed more complex than other techniques. Siau, Erickson and Lee (2002) proposed that Rossi and Brinkkemper’s metrics present the theoretical maximum complexity, known as theoretical complexity. This is …
Non-Parametric Estimation Of Roc Curves In The Absence Of A Gold Standard, Xiao-Hua Zhou, Pete Castelluccio, Chuan Zhou
Non-Parametric Estimation Of Roc Curves In The Absence Of A Gold Standard, Xiao-Hua Zhou, Pete Castelluccio, Chuan Zhou
UW Biostatistics Working Paper Series
In evaluation of diagnostic accuracy of tests, a gold standard on the disease status is required. However, in many complex diseases, it is impossible or unethical to obtain such the gold standard. If an imperfect standard is used as if it were a gold standard, the estimated accuracy of the tests would be biased. This type of bias is called imperfect gold standard bias. In this paper we develop a maximum likelihood (ML) method for estimating ROC curves and their areas of ordinal-scale tests in the absence of a gold standard. Our simulation study shows the proposed estimates for the …

An Empirical Investigation On End-Users’ Acceptance Of Enterprise Systems, Fiona Fui-Hoon Nah, Xin Tan, Soon Hing Teh
Research Collection School Of Computing and Information Systems
Despite the huge investments by organizations in ERP implementation, maintenance, and user training, ERP implementation failures and less-than-satisfactory productivity improvements are common. End-users’ reluctance or unwillingness to adopt or use the newly implemented ERP system is often cited as one of the main reasons for ERP failures. To examine factors leading to the lack of end-user acceptance of ERP systems, we reviewed the literature on user adoption of IT in mandatory contexts, developed hypotheses to explain ERP user acceptance, and conducted a survey study to test the hypotheses. In particular, we examined end-users’ attitudes toward system use and symbolic adoption, …
Haptic Gdraw: A Fun And Easy To Use 3d Haptically Enhanced Sculpting Program, Rick Komerska, Colin Ware
Haptic Gdraw: A Fun And Easy To Use 3d Haptically Enhanced Sculpting Program, Rick Komerska, Colin Ware
Center for Coastal and Ocean Mapping
We have developed a simple haptically-enhanced 3D sculpting application which utilizes Hermite spline-based primitives as building blocks to construct more complex solid models. To accomplish this, we have constructed a VR work environment which is intuitive and whose control affordances are made clear through the use of graspable handles. Haptics is used to support handle selection and provide physical constraints on handle movements consistent with their visual affordances. Our goal is to demonstrate how relatively simple haptic force constraints can combine with a visually intuitive and compelling environment to enable a program that is fun and easy to use.
Animal Model Research: The Apples And Oranges Quandary, Kenneth J. Shapiro
Animal Model Research: The Apples And Oranges Quandary, Kenneth J. Shapiro
Experimentation Collection
In this paper, I explore the premises underlying the problem of the evaluation of animal models. I argue that the presence of similarities and differences between the model and the modelled, although historically and currently a dominant antinomy framing evaluation, is not a bottom-line consideration. What is critical is 1) whether we learn and 2) whether we improve treatment through the animal model research. Similarity between model and modelled and the closely related concept of validity are not coterminus with these critical evaluative measures. In fact, differences between the model and modelled also can provide impetus to new understanding and …

Algorithmic Fusion Of Gene Expression Profiling For Diffuse Large B-Cell Lymphoma Outcome Prediction, Qiuming Zhu, Hongmei Cui, Kahai Cao, Wing C. Chan
Computer Science Faculty Publications
Many different methods and techniques have been investigated for the processing and analysis of microarray gene expression profiling datasets. It is noted that the accuracy and reliability of the results are often dependent on the measurement approaches applied, and no single measurement so far is guaranteed to generate a satisfactory result. In this paper, an algorithmic fusion approach is presented for extracting genes that are predictive to clinical outcomes (survival-fatal) of diffuse large B-cell lymphoma on a set of microarray data for gene expression profiling. The approach integrates a set of measurements from different aspects in terms of the discrepancy …

Proprietary And Open Systems Adoption In E-Procurement: A Risk-Augmented Transactions Cost Perspective, Robert J. Kauffman, Hamid Mohtadi
Research Collection School Of Computing and Information Systems
We present an economic model that enables the study of incentives for business-to-business (B2B) e-procurement systems investments that permit inventory coordination and improved operational control. We focus on the information technology adoption behavior of firms in the presence of transaction costs, agency costs and information uncertainty. We conclude that it is appropriate to rethink the prior theory and develop an extended transaction-cost theory perspective that incorporates the possibility of shocks. We distinguish among three kinds of B2B e-procurement systems platforms. Proprietary platform procurement systems involve traditional electronic data interchange (EDI) technologies. Open platform procurement systems are associated with e-market Web …

UML (Unified Modeling Language) has been criticized for its complexity, relating to users, and those learning to use it. Using Rossi and Brinkkemper’s [9] complexity metrics, Siau and Cao [10] completed a complexity analysis of UML and 36 other modeling techniques, finding that UML is indeed more complex than other techniques. Siau, Erickson and Lee [11] argued that Rossi and Brinkkemper’s metrics present the theoretical maximum complexity, as opposed to a practitioner-based complexity, that must be less than the theoretical maximum. The current research proposes that a subset of UML (a kernel) composed of the most commonly used constructs, would …

Furthering The Understanding Of Practical Complexity: Identifying A Kernel Of Uml, J. Erickson, Keng Siau
Research Collection School Of Computing and Information Systems
The Unified Modeling Language (UML) was adopted by the Object Management Group as the standard visual modeling language for OO systems development. However, UML has been criticized in the literature for its complexity, inconsistent semantics, and ambiguous constructs. A set of complexity indices for UML in aggregate, and the nine diagramming techniques individually, was compiled recently. Since this set of metrics is based on inclusion of all possible constructs in UML, it thus provides an indication of the theoretical (maximum) complexity of the modeling methods. This paper contends that in practice, developers do not use all of the possible diagrams …
