An empirical assessment of the cross-national measurement validity of graded paired comparisons

The popular use of graded paired comparisons in empirical studies assessing consumers’ preferences, and the potential effect of cross-national differences in (extreme) response styles on the quality of graded paired comparison data, supply ample reasons for an empirical verification of the cross-national validity of such scales. Using data from a cross-national margarine brand study including fourteen different nations (N = 4,560), we found sufficient statistical evidence for cross-national bias due to existing cross-national differences in extreme responses. However, the low values reported for effect size measures (intra-class correlation coefficient, R ² value) indicated that the impact of the cross-national bias is marginal. The findings from our study provided empirical support for the hypothesis that graded paired comparison data can be meaningfully compared across nations.     

The Dynamics of Alliance Conditions in the Alliance Development Process

One of the key issues in understanding the developmental processes of strategic alliances is how the alliance conditions change over the different stages of alliance development. A related question concerns the nature of the co-evolutionary dynamics of alliances in terms of their constituent partner firms. In this article we propose an integrated process model of alliances that is based on alliance conditions, allianc developmental stages, and an alliance system comprising co-evolutionary elements. We suggest that alliance conditions, or the key characteristics of an alliance at any given moment, link the alliance environment (firm characteristics) and the alliance development process. We also explore how specific patterns of alliance conditions have differential impacts on the interactive elements of the alliance co-evolutionary system.     

How entrenched managers beat earnings expectations before and after SOX

This study investigates the relationship between managerial entrenchment and how firms meet or beat earnings forecasts. It further examines whether this relationship changes before and after the Sarbanes–Oxley Act (SOX). We find that, in the pre-SOX era, entrenched managers meet or exceed analyst forecasts more often than their unentrenched counterparts when analysts’ initial forecasts are high. This is mainly due to the drop in analysts’ consensus rather than earnings management. These results nearly disappear in the post-SOX era.     

Restructuring materiel management functions: a method for prioritizing changes and reducing costs

The success of any manager depends highly on the ability to seize on opportunities that will achieve the organization's goals. Hospitals are currently searching for ways to reduce costs while maintaining or enhancing the quality of services. Quality services are increasingly being defined as those that are most responsive to customer needs. It is important, as hospital management restructures materiel systems or methods of operation for reduced costs, to focus on the user departments as the customers. The consolidation of materiel management activity should not be seen as a loss of control at the user department level. Instead it can be seen as a new way of providing service with higher quality. User departments should see concrete benefits on a weekly basis, including reduced time spent on materiel management functions; increased planning of purchasing, inventory, and distribution functions; and assistance in meeting restricted supply budgets.     

Do quality perceptions of health and social services vary for different ethnic groups? An empirical investigation

The United States is now more ethnically diverse than any other time in its history. In 2000, minority ethnic groups comprised 26% of the US population; by 2010, they comprise 35%, and in 2080 they will form the majority of American citizens. And among these ethnic groups, African Americans (12.4%), Hispanics (15.4%) and Asians (4.4%) were the most predominant in 2000. The growth of this segment of the population is not only in terms of numbers but also in terms of economic development. Minority groups are showing marked improvement in income and education levels leading to greater purchasing power. As a result, for‐profit companies are increasingly targeting minority populations with products and promotions specifically designed for specific minority groups. Even non profit organizations such as educational programs, social service and healthcare agencies are striving to design specific services and culturally competent outreach models in order to serve this increasingly diverse marketplace. But despite the strides made by non profit agencies, several studies note the tremendous disparities between the ethnic and racial groups in the seeking and the receipt of health‐care and social services. Additionally, there is limited empirical information about the perceptions of minority consumers. In order to effectively serve minority groups, it is essential to understand their experiences with the non profit service industry and to assess their ongoing concerns. In this study, we focus on two critical components of the non profit world – healthcare and social services. We conducted a survey to compare and contrast the social service and health‐care quality perceptions of three ethnic groups: Caucasians, African‐Americans and Hispanics. Our study, undertaken in collaboration with community health centers, reveals distinct differences in perceptions between the three ethnic groups. Based on our findings, we outline a set of implementable strategies for social service and community health organizations. Copyright © 2010 John Wiley & Sons, Ltd.     

PLANNING AND TACTICAL FACTORS IN THE PROJECT IMPLEMENTATION PROCESS

It has been a well-recognized axiom in project management research that the project implementation process can be greatly facilitated by addressing a variety of project critical success factors. It is argued here that critical factors often fall into two distinct sub-groups: those related to initial project planning and those concerned with subsequent tactical operationalization. A field study was conducted to explore changes in the perceived importance of project planning and tactical factors across four stages in the project life cycle. The sample consisted of 408 managers currently involved in projects. It was found that the relative importance of planning and tactical factors varies across the project life cycle. Further, the perceived importance of these factors is contingent upon the type of success measure employed. When an efficiency success measure is used, planning factors are initially perceived to be of high importance but are overtaken by tactical issues as the project progresses through its life cycle. When ‘external’ success measures (perceived value of the project and client satisfaction) are employed, project planning factors dominate tactics throughout the project's life cycle. Finally, implications for managers are developed and directions for future research are discussed.     

On a class of correlated queueing problems

This paper deals with a steady state behaviour of a discrete time, single channel, first come first served, finite space queueing problem. It is assumed that the departure probabilities depend on the queue length and that the departure at two consecutive time marks are correlated. The arrivals at two consecutive time marks are statistically independendent. However, the arrival probabilities are assumed to depend on the queue length. A few particular cases have also been discussed.     

Dynamics and equilibrium in a structural model of wide‐body commercial aircraft markets

This paper develops and estimates a dynamic equilibrium model of the market for new and used commercial aircraft. The model is estimated by maximum simulated likelihood using data on wide‐body aircraft owners and prices for transactions occurring 1978‐1997. The importance of explicitly modeling dynamics and equilibrium in new and used markets for durable goods is illustrated in two counterfactual experiments. Estimates of the structural model are used to show that implementing an investment tax credit not only increases demand for new wide‐body aircraft by the airlines that receive the tax credit, but also increases the number of new wide‐body aircraft owned by airlines not directly affected by the policy. Further, the model indicates that a policy which improves the efficiency of secondary markets for used wide‐body aircraft will also stimulate demand for new wide‐body aircraft.
