GROWING AN ENVIRONMENTAL STRATEGY

Environmental management is becoming increasingly accepted as a key feature of business strategy. However, academic and practitioner publications on the subject develop few guides as to which processes to follow to integrate environmental concerns and strategy. A three-step strategic management process is proposed which incorporates concern for the natural environment throughout a firm's operations. This can result in the growth and nurturing of an organizational environmental strategy.     

Large time-varying parameter VARs

In this paper, we develop methods for estimation and forecasting in large time-varying parameter vector autoregressive models (TVP-VARs). To overcome computational constraints, we draw on ideas from the dynamic model averaging literature which achieve reductions in the computational burden through the use forgetting factors. We then extend the TVP-VAR so that its dimension can change over time. For instance, we can have a large TVP-VAR as the forecasting model at some points in time, but a smaller TVP-VAR at others. A final extension lies in the development of a new method for estimating, in a time-varying manner, the parameter(s) of the shrinkage priors commonly-used with large VARs. These extensions are operationalized through the use of forgetting factor methods and are, thus, computationally simple. An empirical application involving forecasting inflation, real output and interest rates demonstrates the feasibility and usefulness of our approach.     

Top manager and network effects on the adoption of innovative management practices: a study of TQM in a public hospital system

This paper reports findings from a study that combined two theoretical perspectives—top manager and network/institutional—to examine the factors influencing organizations to adopt innovative management practices. The study setting was a system of public hospitals and the innovation was Total Quality Management (TQM). Study results indicate that both top manager and network/institutional factors are important determinants of whether and when organizations adopt innovations. However, as predicted, the relative importance of these two sets of factors appears to change as an innovation becomes more widely diffused. Copyright © 2001 John Wiley & Sons, Ltd.     

Bayesian inference in a time varying cointegration model

There are both theoretical and empirical reasons for believing that the parameters of macroeconomic models may vary over time. However, work with time-varying parameter models has largely involved vector autoregressions (VARs), ignoring cointegration. This is despite the fact that cointegration plays an important role in informing macroeconomists on a range of issues. In this paper, we develop a new time varying parameter model which permits cointegration. We use a specification which allows for the cointegrating space to evolve over time in a manner comparable to the random walk variation used with TVP–VARs. The properties of our approach are investigated before developing a method of posterior simulation. We use our methods in an empirical investigation involving the Fisher effect.

Recently, Formato derived a useful formula of the amount of periodic equal payment in a skip payment loan with arbitrary skips using a second-order finite difference equation. We rederive his formula using simple arithmetics and provide an intuitive explanation of the formula. We also extend his result to the case that periodic payments occur in a geometric-gradient-series.     

On Marxism,Pragmatism and Critical Urban Studies

This article explores the possibilities of philosophical pragmatism for critical theory in urban studies. It points to the philosophical connections between pragmatism and the mainstay of critical theory in urban studies — Marxism. The article suggests how these philosophical roots as well as contemporary developments of pragmatism in social science (and in critical theory) open out the terrain of critical urban studies to make it more pluralist and democratic, theoretically and politically. The article concludes by looking at some of the consequences of this pragmatic turn for critical urban theory.     

The Effect of State Tax Preferences on the Living Arrangements of Elderly Individuals

The United States is in the midst of profound demographic changes. The proportion of the elderly population (65+) in the country is projected to increase from a current 13% of the population to just over 20% of the population by 2030. Considering that the decision regarding living arrangements is of great consequence to the well-being of the elderly and their families, understanding the factors that influence this decision is of great value. In this paper, we exploit the changes in state income tax preferences over time to examine the impact of such tax policies on the living arrangements of the elderly population.     

A Computational Model of Coordination for the Design of Organizational Decision Support Systems

The Information Technology (IT) for realizing Organizational Decision Support Systems (ODSS) is in a nascent stage of development. This is particularly true in the area of coordination, which is a critical element of ODSS, and which distinguishes ODSS research from earlier research in Group DSS and individually oriented DSS. As a first step in ODSS coordination research, alternative representation schemes need to be examined in terms of both their match with the prevailing needs of organizations and of existing IT approaches that can be brought to bear. Matching ODSS needs with coordination representation requirements is examined by using several supporting reference disciplines including foundational DSS and recent ODSS research frameworks/architectures. Existing IT approaches are adapted from the reference disciplines of Active DSS, Distributed Artificial Intelligence (DAI), and Mathematical/Computational Organization Theory (MCOT) to operationalize a computational model of coordination that: (1) embodies the philosophies of Active DSS—including the idea that automated intelligent agents can play a significant role in supporting decision makers by independently carrying out rudimentary tasks to support the various phases of a decision making process; (2) adapts DAI and IT approaches to reflect practical human organizational realities including what we refer to as the ‘Open-Ended Knowledge World‘, and the evolutionary nature of organizations—whereby ODSS coordination representations will be subjected to almost constant revision due to both external environment disruptions and internal events that require adjustments to a preliminary plan; and (3) reflects the fact that organizational goals are often vague, which implies that a coordination representation should be sufficiently robust to reflect ad hoc analysis accommodating of strategy changes.     

From Experience: Securing Sponsors and Funding for New Product Development Projects—The Human Side of Enterprise

Gaining approval for a project requires playing a role that may be unfamiliar for many new-product development (NPD) professionals—that of salesperson. The NPD professional must sell management on the market potential of the product concept, and persuade management to commit the resources needed for transforming the concept into a marketable product. Finding a well-placed sponsor within the company's management ranks can improve the chances of obtaining approval for a project, but securing sponsorship is, in many respects, yet another sales job. Gary Tighe offers guidance for NPD professionals who must sell their projects to potential sponsors. He describes the key steps in the process of securing a sponsor, he gives guidelines for choosing the right sponsor based on the nature of the project, and he provides practical advice for developing a presentation that will gain the support of a prospective sponsor and company management. He then presents a vignette that illustrates the principles he discusses. He identifies three elements that are necessary for securing a sponsor and obtaining funding for a proposed project: clearly defining the project, its scope, and its objective; specifying how the proposed project affects the prospective sponsor and that person's organization; and detailing the project's effects on revenue, profits, cost, or output. These elements forge a strong link between project outcomes and the interests of the sponsor, the sponsor's organization, and the company as a whole. Choosing the right sponsor requires careful consideration of the project's expected effects on specific functional areas and the entire organization, the resources required, the project objectives, and time constraints. For example, senior management sponsorship is essential for projects that cut across existing organizational boundaries. After helping to ensure that projects receive adequate funding, sponsors may serve as advisers to project teams, and they may provide additional resources if a team encounters unexpected problems. Through regular progress reports and sponsor participation in team meetings, the project team can ensure the active, ongoing support of the sponsor.
