Electronic integration--the use of information technology to reengineer key business processes and business relations--enables new forms of organization that transcend traditional industry and firm boundaries. Indeed, electronic integration strategies alter the fundamental structure of both firms as well as their environments, requiring a shift in the study of organizations from the level of a focal firm to that of the business network. The business network represents the pattern of interdependent relationships between the activities of a given firm and those of other firms in its competitive environment that influence each other's strategies.We analyze here the effects of electronic integration on organization structure and competitive processes at the level of the business network. We propose the roles-linkage perspective as a useful abstraction to characterize the business network and guide research on the effects of information technology on industry structures. Building and analyzing the effects of electronic filing on the tax preparation market, we build a preliminary model of how electronic integration strategies alter roles and linkages in a business network.The contributions of this article are a provisional theory of electronic integration at the level of the network, and an abstraction mechanism to characterize and study business networks.

Since the 1960s privacy advocates have relied on regulatory and legislativeapproaches to privacy protection in the United States, Canada and Europe. Whileimportant progress has been made in certain areas, there are large gaps andsignificant loopholes in existing legislation. I argue that a market-based approachto privacy protection would be far more effective and efficient in protectingindividual information than current approaches.

This paper reports on the results of two studies involving the development and construct validation of a short-form measure of the Career Orientations Inventory. The Career Orientations Inventory is a questionnaire designed to assess an individual's career interests, career values, and career motivators. The measure evaluates nine career orientations: technical, managerial, autonomy, job security, geographic security, service, pure challenge, life-style, and entrepreneurship. A short form of this questionnaire was derived and tested in two separate field studies of IS employees. Extensive evidence of the reliability and validity of the measure was demonstrated in both studies (the development, Study 1, and the validation, Study 2). The relationships between career orientations and various individual difference and satisfaction measures were also tested and provided additional evidence of the construct validity of the short-form measure. Researchers and practitioners who need to measure the career orientations of IS personnel should find this a useful questionnaire.

Various techniques have been proposed to ensure the safe, concurrent execution of a set of databasetransactions. Locking protocols are the most prominent and widely used of these techniques, with two-phaselocking and tree-locking being but two examples of these protocols. A locking protocol defines ageneral set of restrictions on the placement of lock and unlock steps within transactions. In this paper weshow that it is possible to further increase the potential level of concurrency of a set of transactions,within the context of a specific locking protocol, by further restricting the placement of lock and unlocksteps within each transaction. We also discuss a variation of the tree-locking protocol that allowstransaction to be locked with respect to a dynamically changing set of tree structures. In addition wedefine and discuss the concept of a concurrency cost function for a locked transaction. This cost functionmeasures the potential for conflict of a transaction with other transactions.

An optimizing translation mechanism for the dynamic interaction between a logic-based expert system written in PROLOG and a relational database accessible through SQL is presented. The mechanism makes use of an intermediate language that decomposes the optimization problem and makes the proposed approach target-language independent. It can either facilitate expert system - database interaction, e.g., when integrating expert systems into business systems, or augment existing databases with (external) deductive capabilities.

The role of the information systems manager has evolved in twenty years from that of a technician managing a relatively unimportant service function into that of a vice presidential-level, general manager who department can substantially impact the entire organization. In this paper we trace, by example, the historical evolution of the job and, through an observational study of six information systems managers, examine the position today. The analysis includes the daily activities of the managers, the nature of the oral contacts that constitute 76% of their day, and other points of particular interest. The information systems managerâs role is depicted as one of coordinator, motivator, and planner, with a cadre of experts, both internal and external, to provide technical information.
