Simulation Modeling Within Workflow Technology, John A. Miller, Amit P. Sheth, Krzysztof J. Kochut, Xuzhong Wang, Arun Murugan

Kno.e.sis Publications

This paper presents an approach for integrating simulation modeling and analysis capabilities within the workflow management system (WFMS) being developed in the Large Scale Distributed Information Systems (LSDIS) Lab at the University of Georgia. Simulation modeling can be used for studying the efficiency of workflow designs as well as studying the general performance and reliability of WFMSs. We also discuss the importance of using sophisticated monitoring and animation capabilities, and the use of workflow management technology to advance simulation technology itself. Finally, we demonstrate a sample simulation where tasks and task managers are simulated.

On The Equivalence Of Upward And Downward Inheritance Reasoners, Krishnaprasad Thirunarayan

Kno.e.sis Publications

In this paper, we analyze systematically the downward (property flow) and the upward (individual flow) views of inheritance for different categories of inheritance networks. We observe that both these views assign the same meaning to tree-structured hierarchies, and explain the divergence in the interpretation of more general networks in terms of their expressive power. This simple analysis sheds light on the inherent nature of nonmonotonic inheritance and can form the basis for the design of efficient algorithms for certain classes of queries. In addition, we describe the notion of preferential inheritance to specify additional conflict resolution information that can be …

Who Determines What Our Children See, Read, Do, Or Learn On The Internet?, Sondlo Leonard Mhlaba

Trotter Review

The issue of appropriate use of the Internet at home and in schools is being hotly debated right now in, and outside, the Internet. In March 1995 Marlene Goss wrote a letter to the discussion list of the Consortium for School Networking ([email protected]) appealing to educational policymakers to focus on access and equity when dealing with Internet in schools, instead of focusing on restricting such access. She found it remarkable how many hours were being spent "deciding student use when only 3% of the classroom teachers, professional adults, have use of the Internet." Her point was not so much that …

The Power Of Information And Communities Of Color, Lana W. Jackman, Patricia C. Payne

Trotter Review

In this age of the Information Superhighway, access to information has become a "human rights" issue for communities of color. Access to information is the backbone for economic growth in the world marketplace. Information literacy, the ability to find, evaluate, analyze, and use information effectively is the currency of infinite power and control of one's economic, social, and political destiny. For communities of color to gain access to this phenomenal communications/technological revolution, there is a need to become information literate.

Empowering Communities Of Color Through Computer Technology, Michael Roberts

Trotter Review

As we hurtle towards the 21st century, an increasing number of individuals start to realize that the ability to use computers and information technology resources effectively will determine how well individuals, organizations, and communities function in a rapidly changing technological society. Numerous studies, including one conducted in the Summer 1995 of Boston's Black community by Freedom House and The Trotter Institute, and highlighted in this issue, have documented the need of Americans—students, workers, unemployed, youth, adults and senior citizens, to become knowledgeable and proficient in the use of computers and information technology. There are several questions that do face communities …

Technological Revolution And The Black Studies Curriculum: A Course Proposal, Abdul Alkalimat

Trotter Review

A technological revolution is changing the world. The computer is fast becoming the universal tool in all aspects of work, production and communication, and innovations in bio-technology are fast transforming agriculture and health. The main impact of this technological revolution has been to restructure the economy, both the centers of accumulation as well as the labor process. It is also restructuring the methods by which people communicate, form and maintain communities. In general, the objective basis of social life is being fundamentally changed.

This essay proposes a basic course that not only focuses on the technological revolution, but should be …

Quest To Own The Information Superhighway: How Much Of It Can Blacks Realistically Expect To Own?, Matthew S. Scott

Trotter Review

On the so-called information superhighway, cable systems, wire telephone lines, cellular services, satellite delivery and broadcast properties are converging to create an interconnecting electronic system on which audio, video and text can travel worldwide. Even though the system is not yet complete, many African Americans have expressed concern that they will somehow be left out on the back roads without an ownership stake. This essay will attempt to answer some of those questions pertinent to this quest of ownership.

Frameworks For Evaluating Technology Transfer, Saskia Wilhelms

Trotter Review

Technology can help us to keep air and water clean, to educate ourselves and others, and to make our lives more comfortable. Technology, however, has in the ears of many, a threatening ring. Whether technology serves human well-being depends on its usage. Dust-covered computers, abandoned factories, underutilized hospitals, chemical plants polluting our environment, nuclear power threatening our health—negative instances of technology application abound. To obtain greater positive results, technology has to be applied and transferred according to criteria that enable us to assess potential benefits and risks associated with the technology. Technology transfer includes tangible and intangible assets, such as …

Democracy, Technology And The Civil Rights Project, Caesar L. Mcdowell, Marianne S. Castano

Trotter Review

Democracy has been defined as "a political system in which the whole people make, and are entitled to make, the basic determining decisions on important matters of public policy." While the United States is often touted as the world's leading proponent of democracy, many U.S. citizens find themselves unable to engage in one of the central acts of democracy—creating public voice through public engagement. Public engagement in the United States is constrained by our inability to talk through our shared, complementary and divergent values. This lack of public engagement and our inability to speak in a "public voice" is also …

Creative Destruction In The Information Age: The Fallout On America's Latino Communities, Anthony G. Wilhelm

Trotter Review

The 104th Congress is in the midst of the first wholesale reform of telecommunications regulation in one-half century. The new regulatory framework emerging in the Republican-controlled Congress, if enacted, will usher in a radically deregulated, market-driven telecom environment, one in which the benefits of the emerging national information infrastructure will likely be distributed differentially, based on ethnicity and socio-economic status. Many U.S. residents may actually be charged higher rates for essential telecommunication services after deregulation (just as they did when cable television was deregulated), which may force many vulnerable users off the network. In addition, the concentration of media ownership …

Computer Utilization And Attitudinal Patterns In A Black Community, James Jennings

Trotter Review

During the Spring and Summer of 1995 The William Monroe Trotter Institute conducted a survey of resident utilization patterns and attitudes towards various facets of computer technology. This survey was commissioned by Freedom House, Inc. and supported with a grant from the AT&T Foundation in Boston, Massachusetts. The goal of this survey, composed of adult residents who have been served by Freedom House, and agency representatives of a small number of selected community-based organizations, is to inform planners at this agency about the computer technical needs, interests, and utilization patterns of its clients.

Introduction, James Jennings

Trotter Review

This issue of the Trotter Review focuses on one of the most important set of challenges facing the Black community in the U.S., and that is, how to access, and manage, and control, significant facets and processes associated with the information superhighway. This current issue identifies the nature of the challenges, but also proposes some strategies that the Black community and its leadership might consider to ensure both access and control over information technology.

Power Systems Marginal Cost Curve And Its Applications, Shaojun Wang, S. M. Shahidehpour, Nian-De Xiang

Kno.e.sis Publications

This paper presents a forward recursive procedure to calculate the expected system marginal cost curve (EMC). The EMC formulation allows for multi-state and multi-block dispatch of generating units and is used to determine the optimal energy of pumped-storage units. A new approach is developed to compute the first and second derivatives of the expected generation energy of a thermal unit with respect to the capacity of all thermal units in the system. The salient feature of the proposed approach is that it applies to hydro-thermal systems with multiple limited-energy hydro units.

A Meta-Interpreter For Circuit-Extraction, Krishnaprasad Thirunarayan

Kno.e.sis Publications

The design of a VLSI circuit consists of a description of the circuit in terms of its components and subcomponents, at various levels of detail. To verify that the layout of a VLSI circuit conforms to its design, one needs to work backwards from the lowest-level description of the circuit and recognize the higher-level components it constitutes. This paper is concerned with the application of logic programming techniques in the formal verification of the structural correctness of the VLSI circuit layouts. In particular, we review Michael Dukes' Generalized Extraction System (1990) that compiles design descriptions into a set of extraction …

Social Status Gradations Expressed In The Beadwork Patterns Of Sarawak's Orang Ulu, Heidi Munan

BEADS: Journal of the Society of Bead Researchers

The peoples of Central Borneo, known collectively as the Orang Ulu, used to display social stratification by restricting the types of ornaments an individual might use and wear. "High-ranking" motifs were the human figure, the hornbill, and the tiger or leopard. The Orang Ulu are bead connoisseurs who incorporated seed beadwork in their costume and belongings; a person could only make use of beaded items proper to his or her social stratum. Religious and social changes have democratized these once strictly aristocratic societies and their handicrafts. Today's beadworker produces not only for her own family but for the souvenir market, …

Prosperity, Reverence And Protection: An Introduction To Asian Beadwork, Valerie Hector

BEADS: Journal of the Society of Bead Researchers

Fascinating and diverse beadworking traditions have flourished in Asia for more than 1000 years, with the preponderance of surviving specimens dating to the 19th and 20th centuries. Based on a lecture presented at the Third International Bead Conference in Washington, D.C., in 1995, this article introduces Asian beadwork as a fruitful topic of inquiry for bead specialists. Representative examples produced in the last millennium by various cultures in South Asia, mainland and island Southeast Asia and East Asia are shown and discussed. Although they certainly testify to the material wealth of their makers, in many cases these pieces also carry …

Mammals and Magnolias users can view videos of the original excavation of each of the sites and also play computer games relating to each location. This project provides a model for how collaboration among museums can reduce the cost of multimedia exhibits while improving quality and making them available to wider audiences.

Nonrecursive Incremental Evaluation Of Datalog Queries, Guozhu Dong, Jianwen Su, Rodney Topor

Kno.e.sis Publications

We consider the problem of repeatedly evaluating the same (computationally expensive) query to a database that is being updated between successive query requests. In this situation, it should be possible to use the difference between successive database states and the answer to the query in one state to reduce the cost of evaluating the query in the next state. We use nonrecursive Datalog (which are unions of conjunctive queries) to compute the differences, and call this process “incremental query evaluation using conjunctive queries”. After formalizing the notion of incremental query evaluation using conjunctive queries, we give an algorithm that constructs, …

The Beads Of Tenth- To Twelfth-Century Hungary, Katalin Szilágyi

BEADS: Journal of the Society of Bead Researchers

An examination of the beads recovered from three Hungarian cemeteries in use during the 10th-12th centuries resulted in the identification of 61 distinct bead types. Seven of these were found to be significant on the basis of frequency analysis, and represent the beads most used by the local population. The study is enhanced by comparative material from a number of other contemporary archaeological sites in and around the country. The classification system developed for this study is applicable to other geographical areas and time periods, and may be expanded or otherwise modified to suit the needs of other researchers.
