Polynomial inequalities for non-commuting operators

We prove an inequality for polynomials applied in a symmetric way to non-commuting operators

Using the Sayre Model to analyze Internet privacy

The Internet continues to evolve as a transportal of electronic commerce. It has penetrated into every facet of organizational life, from the ordering of commodity goods to providing a means to speed the recording and payment of federal income taxes. Internet usage continues to expand rapidly, surfacing issues in its wake that must be managed in order for it to ensure that it is viable as a long-term strategic tool for government and industry. To bridge the legal gap that has emerged as a result of the dynamic growth of the Internet, the United States Congress has acted to begin to address issues such as access to information and the unauthorized use of personal data. Though the issues themselves are not new, the amount of information and the rapidity of transfer of the information have been greatly expanded by the use of the Internet. This paper explores the relationship between the three dimensions (government, individual consumer needs and business as represented by industry groups) that are influencing the development of a legislated Internet privacy model

Competing in the Virtual World: E-Commerce Factors that affect the Property-Casualty Insurance Industry

Electronic commerce has exploded; its expansion projections are consistently understated. We explore the current state of the property-casualty insurance industry use of the Internet for electronic commerce, by analyzing the factors that affect the expansion and use of electronic commerce in the property-casualty insurance industry. The insurance industry has embraced the use of technology to expand its market and to provide better customer service. Competition within the United States has expanded recently to include companies in Europe and Asia. A survey of property-casualty insurance company web sites was performed to determine what types of services and features are currently offered through the Internet. Thirty-six web sites were sampled and the results showed that while no insurance company currently offers a fully electronic policy purchase process, there are a variety of services that are provided for through their web sites. The more common web based features include the ability to locate an agent, the ability to find information about how to report a claim, and the ability request a quote. Use of the Internet as a tool for electronic commerce within the insurance industry has not yet been fully utilized

Non-commutative automorphisms of bounded non-commutative domains

We establish rigidity (or uniqueness) theorems for non-commutative (NC) automorphisms that are natural extensions of classical results of H. Cartan and are improvements of recent results. We apply our results to NC domains consisting of unit balls of rectangular matrices

E-Commerce Adoption in the Insurance Industry

While other industries within the financial sector have vigorously embraced the Internet to obtain sustainable competitive advantage, the insurance industry has been slow to fully adopt e-commerce. This article examines the barriers as well as the success factors involved in making the transition to a Web-enabled insurance model. Emerging standards and technologies that will make possible the next generation of e-commerce in the insurance industry are discussed and a proposed research agenda is presented

Building Relationships That Last: Integrating Public Relations Into Web Design

This paper explores the relationship between web site design, public relations strategy, and a consumer\u27s intention to return to a web site. This relationship is defined through a model that explores the influence of information satisfaction, particularly when the web site design is congruent with the consumer\u27s expectations. The public relations dimension extends the consumer web site design model by interjecting a long-term focus on relationship building that organizations will need to make electronic commerce a viable investment in information technology resources. This is significant because it recognizes the importance of developing loyalty and trust online

The Relationship of E-Commerce Readiness to Technology Acceptance: The Case of Barbados

This is an exploratory study that examines the relationship between selected components of ecommerce readiness and dimensions of Davis’ (1989) Technology Acceptance Model. Building upon the notion that there exists some linkage between ecommerce readiness and technology Acceptance, this study seeks to examine these linkages in e-businesses within Barbados. Three relationships are proposed – a relationship between technology acceptance and the existing e-Readiness infrastructure, a relationship between technology acceptance and current telecommunications access, and a relationship between technology acceptance and education. The results of this study demonstrated that there are strong relationships between e-commerce readiness components and various technology acceptance dimensions
