Decision Production-- A Step Toward a Theory of Managerial Information Requi rements

The lack of a general theory of managerial information requirements is proposed as an underlying cause of the many MIS failures. This paper takes a first step toward developing such a theory. Viewing decision making as a production process (decisions being produced in much the same manner as normal goods or services), microeconomic concepts are employed to provide descriptive and normative guidance for the development of MIS

Identifying Appropriate MIS/DSS Support: A Cost Analysis Approach

This paper describes a microeconomic theory-based tool, called cost analysis, which can be used in MIS research to develop guidance for systems analysts and information resource managers. An example of this guidance is a matrix of decision making contexts versus appropriate MIS/DSS support. Systems analysts can use this matrix to help identify appropriate MIS/DSS design alternatives. Information resource managers can use this matrix to help plan for the proper evolution of MIS/DSS support

THE DESIGN OF COMPUTER BASED SUPPORT FOR TASK COMMUNICATION WITHIN ORGANIZATIONS

Task communication plays an important role within organizations, facilitating the conversion of inputs to outputs and the coordination and control of internal activities. An important function of several computer based information technologies is to support task communication. However, information systems designers do not have a framework that can help them select information technology that will provide efficient and effective communication support. This paper integrates the organization and information systems literatures in order to develop guidelines for the selection of appropriate communication support technology

A contingent cost analysis of alternative manufacturing information systems

The evaluation of alternative management information systems can aid systems analysts determine appropriate information support for managers, aid managers to become informed participants in the system design process, and aid the planning of information systems in response to changes in the firm. Synthesizing microeconomic and contingency theories, this paper performs a cost analysis of two popular manufacturing information systems. The relative cost-effectiveness of these two systems is hypothesized and then validated using a random survey of manufacturing firms across the USA. A logistical regression of the data provides estimates of the relative information system cost-effectiveness in various manufacturing contexts.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26585/1/0000126.pd

Review of management information systems research: A management support emphasis

This article organizes, describes, and evaluates MIS research from 1981 through 1985 in order to provide an understanding of what constitutes MIS research and to indicate potentially rich areas for future research. The review emphasizes information systems research in support of management decision making as opposed, for example, to research into the management of information resources or the development of strategic information systems.Preliminary work includes developing a definition of MIS, adopting an organizing framework, and choosing journals for review. Once this foundation is laid, MIS research content and methodology up to 1980 are summarized based upon the findings of the First International Conference on Information Systems. Finally, MIS research from 1981 to 1985 is described and evaluated in terms of content and methodology.It was found that more progress has been made in identifying appropriate research questions than in answering those questions. Significant progress in generating answers may be made in the future due to a healthy shift in the choice of methodologies (shift from more speculative-conceptual to more theory-based/theory-generating empirical). However, progress toward developing a global notion (theory) of MIS seems relatively slow. This lack of progress seems to be a symptom of: - Lack of progress in defining the product of MIS (information). - Too much research focus upon what relationships exist instead of focusing upon why relationships exist. - Underlying problems in the natural sciences paradigm currently associated with MIS research.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27465/1/0000506.pd

A Note on the Regularity of the Solutions to Two Variational Inequalities Involving a Pseudodifferential Operator

The regularity of solutions to variational inequalities involving local operators has been studied extensively. Less attention has been paid to those involving nonlocal pseudodifferential operators. We present two regularity results for such problems

Communicating MIS research: A citation study of journal influence

Due to difficulties with objectively evaluating the quality of MIS research, attitudes about journals in which this research is published play an important role in determining the allocation of research resources. To provide a more objective basis for these attitudes, we examine journal influence in communicating MIS research over a 9-year period using citation analyses, researcher perceptions, and publishing patterns of top MIS research universities. As a result of these analyses, we identify a cohesive stable group of highly influential journals which can reasonably be called an MIS core. An internal ranking of this core is then determined which is significantly different from prior rankings.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31049/1/0000726.pd

Fraser of Allander Institute : Economic Commentary [October 2022]

This quarter's Commentary leaves us in no doubt as to the difficult economic conditions we all currently face. While the first quarter of 2022 was characterised by cautious optimism, as Covid-19 restrictions were lifted and Scotland's economic recovery seemed underway, over the last 6 months historic increases in inflation and cost-of-living pressures have compounded to create a deteriorating economic environment. The Fraser of Allander has now significantly revised down its forecasts for growth for Scotland's economy in 2023 and 2024, with contractions in activity expected in the last two quarters of this year, and first quarter of 2023, meaning Scotland is likely to enter a recession. Industry and consumers alike are bracing for a downturn. The UK Government's growth plan or 'mini-budget' on 23 September announced that taxpayers in the rest of the UK will benefit from a cut in the Basic Rate of Income Tax (from 20% to 19%) from April next year. At the time of writing, the UK Government has said it will no longer proceed with the abolition of the Additional Rate for those earning over £150,000 a year, which had also been proposed as part of the growth plan and would have created a material divergence in income tax rates between Scotland and the rest of the UK for the highest earners. However, the change in the basic rate of income tax still presents the Scottish Government with a decision. Should they use the Block Grant Adjustment to pass on the benefit of a 19% basic rate of income tax or maintain the 21% Intermediate Rate for individuals earning over £25,689? Businesses and individuals will be keenly awaiting the response from Holyrood

The Neighboring Sulfonium Group in Ester Hydrolysis. III

Z- and E-2-carbomethoxy-3-(methylenedimethylsulfonio)-bicyclo- [2.2.2]octane p-toluenesulfonate (8z and 8e, respectively) were synthesized and saponified at constant pH to study the effect of the neighboring sulfonium group on the rate of reaction. Rates and activation parameters are very similar for both isomers, lending support to the theoretical prediction that charge-dipole and charge-charge separation in both isomers is not significantly different, and that the carbonyl-dipole vector is nearly normal to a line connecting it with the sulfonium sulfur atom
