DEVELOPING POM FACULTIES FOR THE 21ST CENTURY

Having added total quality management (tqm), operations strategy, new product development, and many other topics to its repertoire over the past two decades, operations management is being pushed-by practitioners and students alike-to extend its reach both horizontally (to encompass the whole supply chain and the interface with other functions) and internationally. Moreover, the increasing sophistication of computer technology and the growth of the intemet are expanding the teaching and research methodologies that can be used to address these complex issues. Meeting the challenges posed by this ever-broadening conceptualization of our mission and the new tools available to us will require more than simply new knowledge and new courses. It also will require an influx of new people having very different backgrounds than in the past. We have to learn how to attract such people, how to prepare them to be effective teachers and researchers in production and operations management (pom), and how to work effectively with them. The locations of faculty, students, and potential partners in the learning experience also will be transformed, forcing us to reconsider how we organize to do our work and when and where we do it.     

ACCESS TO TECHNOLOGY AND THE TRANSFER FUNCTION OF COMMUNITY COLLEGES: EVIDENCE FROM A FIELD EXPERIMENT

Access to information may represent an important barrier to learning about and ultimately transferring to 4‐year colleges for low‐income community college students. This article explores the role that access to information technology, in particular, plays in enhancing, or possibly detracting from, the transfer function of the community college. Using data from the first‐ever field experiment randomly providing free computers to students, we examine the relationships between access to home computers and enrollment in transferable courses and actual transfers to 4‐year colleges. The results from the field experiment indicate that the treatment group of students receiving free computers has a 4.5 percentage point higher probability of taking transferable courses than the control group of students not receiving free computers. The evidence is less clear for the effects on actual transfers to 4‐year colleges and the probability of using a computer to search for college information (which possibly represents one of the mechanisms for positive effects). In both cases, point estimates are positive, but the confidence intervals are wide. Finally, power calculations indicate that sample sizes would have to be considerably larger to find statistically significant treatment effects and reasonably precise confidence intervals given the actual transfer rate point estimates.

Racial Disparities in Drug Court Graduation Rates: The Role of Recovery Support Groups and Environments

There are more than 3,000 drug courts in the United States, and research has demonstrated that, in some drug courts, African American participants are less likely to graduate than their White counterparts. Quantitative studies have documented the problem, but qualitative studies are needed to develop an in-depth understanding of this phenomenon through participants’ experiences. This qualitative study asked African American participants (n = 31) about their lived experiences in drug court to develop insight into the factors that might contribute to racial disparities in drug court outcomes. African Americans had favorable views toward both mandated and natural recovery support groups, and they felt that participating in these support groups increased their likelihood of graduating drug court. Conversely, African Americans felt that a barrier to graduating drug court was their environments, mainly risk factors posed by family, neighborhoods, and peers. Implications for drug court practice are discussed.     

THE DETERMINANTS OF U.S. STATE ECONOMIC GROWTH: A LESS EXTREME BOUNDS ANALYSIS

This study investigates U.S. state economic growth from 1970 to 1999. I innovate on previous studies by developing a new approach for addressing "model uncertainty" issues associated with estimating growth equations. My approach borrows from the "extreme bounds analysis" approach of Leamer while also addressing concerns raised by Granger and Uhlig, Sala-i-Martin, and others that not all specifications are equally likely to be true. I then apply this approach to identify "robust" determinants of state economic growth. My analysis confirms the importance of productivity characteristics of the labor force and industrial composition of a state's economy. I also find that policy variables such as (1) size and structure of government and (2) taxation are robust and economically important determinants of state economic growth.

DYNAMIC GRAPHICAL ASSESSMENT OF INTERACTION EFFECTS IN DESIGN OF EXPERIMENTS

Design of experiments has been and continues to be employed successfully for the robust design of products/processes. A principle contention in these areas of application concerns whether or not interactive effects should be estimated. The arguments, for and against, hinge on an experimenter's understanding of the interaction concept and on the value added that is derived from the increased effort required for assessing such effects. We propose an interactive graphics approach that assesses whether and which interactive effects to estimate. Our methodology yields several additional benefits to the experimenter that include prototype simulation and unique learning opportunities for augmenting process knowledge in post-analysis.     

THE QUALITY REVOLUTION

Our understanding of quality has undergone great changes over the last decade, propelled forward by the quality paradigm that has evolved in Japan. This paradigm has rendered obsolete the traditional quality-cost trade off model. I outline the key elements responsible for forcing a new understanding of quality-cost relationships.
