The Spectacularization Of Subjectivity: Media Knowledges, Global Citizenry, And The New World Order, Rhonda Hammer, Peter Mclaren

Education Faculty Articles and Research

"Our understanding of contemporary forms of electronically produced media knowledges has been informed by what we perceive as the changing role of the flaneur in the age of late capitalism-one that is as ominous and drastic as the changes which Benjamin perceived. We suggest that the flaneur no longer provides the service of teaching his or her generation about 'their own objective circumstances;' rather, we suggest that the flaneur, as global newscaster, has transmogrified into the afterimage of fascism."

Specifying Interdatabase Dependencies In A Multidatabase Environment, Marek Rusinkiewicz, Amit P. Sheth, George Karabatis

Kno.e.sis Publications

The problem of interdatabase dependencies and the effect they have on applications updating interdependent data are addressed. A model that allows specifications of constraints among multiple databases in a declarative fashion is proposed. The separation of the constraints from the application programs facilitates the maintenance of data constraints and allows flexibility in their implementation. It allows investigation of various mechanisms for enforcing the constraints, independently of the application programs. By grouping the constraints together, it is possible to check their completeness and discover possible contradictions among them. The concepts of polytransactions, which use interdatabase dependencies to generate a series of …

A Study Of The Adoption And Effectiveness Of Electronic Mail At The Air Force Institute Of Technology, Douglas D. White

Theses and Dissertations

This research investigated the relationship between the adoption and effectiveness of electronic mail at the Air Force institute of Technology's School of Systems and Logistics (LS). In this research, theories concerning innovation adoption and measurement of system effectiveness are discussed. Survey instruments from both areas were selected, tested, and used to collect data from the LS faculty and staff. Correlation analysis was performed using the data collected. Findings indicate a correlation does exist between the adoption of electronic mail and the effectiveness surrogate measurement, user satisfaction. There was a significantly strong negative correlation between electronic mail complexity and user satisfaction.

On The Relationship Between Parsimonious Covering And Boolean Minimization, Venu Dasigi, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Minimization of Boolean switching functions is a basic problem in the design of logic circuits. The designer first comes up with a switching function expressed in terms of several binary input variables that satisfies the desired functionality, and then attempts to minimize the function as a sum of products or product of sums. It turns out that a sum of products form of a switching function that has no redundancy is a union of prime implicants of the function.

In this paper we would like to explicate some of the relationships of the boolean minimization problem to a formalization of …

The Architecture Of Braid: A System For Bridging Al/Db Systems, Amit P. Sheth, Anthony B. O'Hare

Kno.e.sis Publications

We describe the design of BrAID (a Bridge between Artificial Intelligence and Database Management Systems), an experimental system for the efficient integration of logic based Artificial Intelligence (Al) and database (DB) technologies. Features provided by BrAID include (a) access to conventional DBMSs, (b) support for multiple inferencing strategies, (c) a powerful caching subsystem that manages views and employs subsumption to facilitate the reuse of previously cached data, (d) lazy or eager evaluation of queries submitted by the AI system, and (e) the generation of advice by the AI system to aid in cache management and query execution planning. To discuss …

On Serializability Of Multidatabase Transactions Through Forced Local Conflict, Dimitrios Georgakopoulos, Marek Rusinkiewicz, Amit P. Sheth

Kno.e.sis Publications

The main difficulty in enforcing global serializability in a multidatabase environment lies in resolving indirect transitive conflicts between multidatabase transactions. Indirect conflicts introduced by local transactions are difficult to resolve because the behavior or even the existence of local transactions is not known to the multidatabase system. To overcome these problems, we propose to incorporate additional data manipulation operations in the subtransactions of each multidatabase transaction. We show that if these operations create direct conflicts between subtransactions at each participating local database system, indirect conflicts can be resolved even if the multidatabase system is not aware of their existence. Based …

Management Of Interdependent Data: Specifying Dependency And Consistency Requirements, Amit P. Sheth, Marek Rusinkiewicz

Kno.e.sis Publications

Multiple databases that serve the needs of various application systems are considered. One of the significant problems in managing these databases is to maintain the related data items consistent to the required degree. This problem is frequently referred to as `redundant data management'. Since the term `redundancy' tends to imply that the data is unwanted or superfluous, the authors use the more general term `management of interdependent data'. Some preliminary ideas in this area are discussed. The problem of managing interdependent data is characterized, and some important types of interdatabase dependency are identified.

Attribute Relationships: An Impediment In Automating Schema Integration, Amit P. Sheth, Sunit K. Gala

Kno.e.sis Publications

Success in schema integration depends on understanding the semantics of schema components (e.g., entity sets, relationship sets, attributes), and the ability to capture and reason about these semantics. An important objective of our work on schema integration is to automate the reasoning as much as possible, and when not possible, depend on the human input and guidance. A key results of comparing the semantics associated with schema objects is that of determining attribute relationship. Once attribute relationships are determined, the task of object class(e.g., entity sets and relationship sets) integration becomes simpler and can e automated to a great extent. …

Fault Tolerance In A Very Large Database System: A Strawman Analysis, Amit P. Sheth

Kno.e.sis Publications

A simple model is used to study the effect of fault-tolerance techniques and system design on system availability. A generic multiprocessor architecture is used that can be configured in different ways to study the effect of system architectures. Important parameters studied are different system architectures and hardware fault-tolerance techniques, mean time to failure of basic components, database size and distribution, interconnect capacity, etc. Quantitative analysis compares the relative effect of different parameter values. Results show that the effect of different parameter values on system availability can be very significant. System architecture, use of hardware fault tolerance (particularly mirroring), and data …

Desert Explorations - A Videodisc Exhibit Designed For Flexibility, Judy Diamond, Alan B. Bond, Atsusi Hirumi

Alan Bond Publications

Using an interactive exhibit does not provide the same experience for everyone. How visitors understand an exhibit, what associations it evokes, and even how it is physically utilized may differ widely. This article describes an exhibit that was designed to let visitors tailor their explorations to their own interests and motivation. The exhibit, called Desert Explorations, gives visitors choices of what to see and how to learn about what they see. This exhibit also is an example of a way of developing interactive videodisc exhibits that is relatively inexpensive yet may be tailored to a particular topic or hall. This …

The Search For Nova University: An Essay On Its First Twenty-Five Years 1964-1989, Stephen L. Goldstein

NSU Books and Book Chapters

Acknowledgement

Twenty-five years in the life of a university is a short period of time. Yet, in its first twenty-five years, Nova University has been able to respond to major changes in American society. After Sputnik was launched in 1957, our government and our educational system placed a high priority on science and technology. President Kennedy declared that we would place a man on the moon within a decade.

Nova University of Advanced Technology was conceived in response to the national agenda. In the mid-1960s, President Johnson launched the Great Society, which began to take effect in the late 1960s …
