A question of ethics: Developing information system ethics

This study develops a pedagogy for the teaching of ethical principles in information systems (IS) classes, and reports on an empirical study that supports the efficacy of the approach. The proposed pedagogy involves having management information systems professors lead questioning and discussion on a list of ethical issues as part of their existing IS courses. The rationale for this pedagogy involves (1) the maturational aspects of ethics, and (2) the importance of repetition, challenge, and practice in developing a personal set of ethics. A study of IS ethics using a pre-post test design found that classes receiving such treatment significantly improved their performance on an IS ethics questionnaire. It appears to me that in Ethics, as in all other philosophical studies, the difficulties ... are mainly due to ... the attempt to answer questions, without first discovering precisely what question it is which you desire to answer.

ECONOMIC OPTIMISATION OF SPRINKLER IRRIGATION CONSIDERING UNCERTAINTY OF SPATIAL WATER DISTRIBUTION*

The study is focused on the development and the application of a stochastic economic optimisation model by which optimal levels of applied water and sprinkler spacing are determined. Data on crop-water production function and uniformity of water application are taken from a sprinkler irrigation plot of sweet corn. It was found that a saving of irrigation water can be achieved not only by raising water prices but also by increasing application uniformity.     

Manure Applications and Nutrient Standards

Because of environmental concerns, many states are regulating animal manure applications to crops. A conceptual model is presented to describe manure demand for crop nutrient application under alternative regulatory standards. Demand relationships are incorporated into a spatial equilibrium model to estimate welfare costs of phosphorus and nitrogen regulatory standards for manure applications. Model estimates for Virginia indicate that regulatory standards for manure application achieve large reductions in excess nitrogen and phosphorus and result in 5–15% welfare losses excluding nonmarket environmental valuation.     

Strategy,strategy-making,and performance in a business game

In a recent study, Segev (1987) examined the relationships among strategy, strategy-making, and performance, focusing on the connection between two important typologies: Miles and Snow's (1978) concept of strategic types and Mintzberg's (1973) concept of strategy-making modes. The findings of that study clearly indicated links between the two, and partially supported propositions asserting the effects of the strategy/stategy-making fit on organizational performance. In the current study a business game served as the vehicle for examining this tripartite relationship. The two typologies were applied to the firms' in the game, and then an inquiry was made into the relationships between them. An hypothesis regarding the effect of fit on performance was tested, and the findings compared with previously reported empirical results.

Valuation of Internet Stocks—An IPO Perspective

We empirically investigate valuations of Internet firms at various stages of the initial public offering (IPO) from two perspectives. First, we examine the association between the valuation of Internet IPOs and a set of financial and nonfinancial variables, which prior anecdotal or empirical evidence suggests may serve as value drivers. Second, we document differences in IPO valuations between Internet and non-Internet firms as well as across different stages in the IPO process—i.e., initial prospectus price, final offer price, and first trading day price—within each set of firms. Our primary two conclusions are as follows. First, there are noticeable differences between valuations of Internet and non-Internet firms, especially at the prospectus and final IPO stage. Specifically, the valuation of non-Internet firms generally follows the conventional wisdom regarding valuation: positive earnings and cash flows are priced, while negative earnings and negative cash flows are not. The valuation of Internet firms, however, departs from conventional wisdom, with earnings not being priced, and negative cash flows being priced perhaps because they are viewed as investments. This difference between the two classes of firms may be expected, given the age and unique nature of the Internet industry. Second, there are significant differences between the initial valuation of firms at the prospectus and IPO stage and their valuation by the stock market at the end of the first trading day. For non-Internet firms, the difference is largely ascribed to the relative offering size. For Internet firms, however, the differences are with respect to positive cash flows, sales growth, R&D, and high-risk warnings, in addition to the relative offering size.     

Interrelationships between environmental dependencies: A basis for tradeoffs to increase autonomy

General managers of large industrial plants in Israel were asked to evaluate the effects of environmental dependencies on their freedom of action. It was found that most segments of the environment were perceived as homogeneous—affecting the firms' autonomy in similar ways. Different components of government, however, were perceived as having conflicting interests both within the segment and with other segments of the environment. When a segment of the environment is heterogeneous, it is possible that managers use a tradeoff strategy, in which pressures generated by one component of the environment can be used as a means to reduce pressure of the other components.
