Exploring the use of QPID: A collaborative study of B2B in the automotive industry

Deep and grounded understanding of complex socio-technical phenomena, such as business-to-business (B2B) information systems, requires a collaborative process of enquiry where the researcher works with practitioners to make sense and establish meaning. This suggests the need for interventionary approaches, such as action research and action case, supported by a method of notation for describing a co-constructed reality to make sense of inter-organizational settings and to undertake cross-case comparisons. This paper tests the conjecture that systems thinking and the qualitative politicized influence diagram (QPID) are an appropriate lens through which to study B2B information systems. It demonstrates how the QPID workshop is valuable in inter-organizational studies as a practical and appropriate method of collaborative investigation. The paper concludes by raising issues for research methodology in terms of limitations of the research method, recommendations for further development, and future plans for incorporating multiple partners in industry-level research.     

Risk analysis and risk management in an uncertain world.

The tragic attacks of September 11 and the bioterrorist threats with respect to anthrax that followed have raised a set of issues regarding how we deal with events where there is considerable ambiguity and uncertainty about the likelihood of their occurrence and their potential consequences. This paper discusses how one can link the tools of risk assessment and our knowledge of risk perception to develop risk management options for dealing with extreme events. In particular, it suggests ways that the members of the Society for Risk Analysis can apply their expertise and talent to the risks associated with terrorism and discusses the changing roles of the public and private sectors in dealing with extreme events.     

Assessing the Height of Mobility Barriers: A Methodology and an Empirical Test in the UK Retail Grocery Industry1

A profitable niche will have few entrants if the presence of significant mobility barriers impedes entry and, hence, reduces the expected rents for entrants. Identifying sources of mobility barriers is critical in explaining how incumbents can sustain competitive advantage and obtain supranormal profits (excess rents). While much of strategic management research (and strategic group research, in particular) focuses on the pursuit of sustainable performance advantages, there is relatively little empirical research exploring the dynamics of firm movement and the impact of mobility barriers on performance. The paper analyses mobility dynamics and, most importantly, develops a method to identify the location and severity of mobility barriers. The method is illustrated on a database of large multiples in the UK retail grocery industry for the period 1982–1986. It appears that there are two dimensions of strategic change that facilitate movement into profitable niches. Implications for competition and profitability are discussed.     

Individual differences in expressive style as a mediator of expectancy communication

This study investigates the role of nonverbal expressiveness and self-monitoring as mediators in the communication of teachers' expectations for student performance to a third party observer. Undergraduates were recruited to be videotaped while teaching a brief lesson to a high school student who was presented as either very bright and motivated or not. Videotapes showing only the teacher were later shown to observers who were asked for their impressions of the student who was being taught. It was hypothesized that teachers who were highly nonverbally expressive would communicate their expectations to the observers, and would thus elicit from them responses quite similar to their own. On the other hand, it was predicted that unexpressive teachers would not communicate their expectations, eliciting observer responses unrelated to their own. The predictions were supported but with a major qualification: it was found that spontaneous expressiveness interacted with self-monitoring in determining expectancy communication. The findings point towards new directions in understanding the occurrence and mediation of expectancy effects.A portion of this paper was presented at the American Psychological Association meetings in Anaheim, California, August, 1983. The research was supported in part by a University of California intramural research grant to the second author, by a UCR minigrant to the third author, and by an NIH biomedical research support equipment grant.     

Personality and the enactment of emotion

The meaning of personality traits for social interaction was investigated by exploring the personality correlates of abilities to pose emotions. This framework focuses on individual differences in socio-emotional skills. Thirty one males and 37 females were videotaped while attempting to communicate seven basic emotions nonverbally (i.e., using standard content communications), and sending success was measured by showing edited videotapes to judges. Hypothesized relationships between acting ability and scores on the Jackson Personality Research Form and the Eysenck Personality Inventory were then examined. The findings were seen to have implications for predicting individual strengths and weaknesses in social interaction as a function of certain personality traits and for understanding person perception.This research was supported in part by NIMH Grant #RO3MH31453 and Intramural Research Grants from UC Riverside to Howard Friedman, and indirectly by the Biomedical Research Support Program of NIH (#RR077010-11).

The State of Surveying Cell Phone Numbers in the United States: 2007 and Beyond

By the late 1970s, household telephone coverage grew to exceed90 percent in the United States, and by the mid-1980s telephonesurveying of the general public had become commonplace. Nevertheless,20 years later, the ability of researchers to reach representativesamples of the U.S. public via landline (wired) telephone surveysand gather reliable data is being seriously challenged for manyreasons, especially those related to cell phones and the growthof the "cell phone only" population. However, at present thereexists no widely accepted set of Cell Phone Surveying "bestpractices" for U.S. survey researchers to follow. Despite whatsome appear to believe, surveying persons reached on cell phonenumbers in the United States currently is a very complex undertakingif one wants to do it "right," i.e. to do it legally, ethically,and in ways that optimally allocate one's finite resources togather the highest quality data, and to analyze and interpretthose data accurately. This final "wrap-up" article in the specialissue provides a review of the empirical articles in the issuewith a focus on their practical implications for the decisionsthat researchers need to make regarding sampling, coverage,nonresponse, measurement, and weighting in surveys that includeinterviews with persons reached on cell phones. The articlealso highlights the practical implications of a number of legal,ethical, and other issues that relate to surveys in the UnitedStates that include cell phone numbers. Surveying the U.S. cellphone population is possible, if at a higher cost than surveyingtheir landline counterparts, and if with less precision thancurrently can be done surveying the landline population. Thenext five years should see a considerable growth in the methodologicaland statistical know-how that the survey community uses to plan,implement, and interpret cell phone surveys. There is a greatdeal that still must be learned.     

Missouri Casino Self-Excluders: Distributions Across Time and Space

According to public health research, exposure to casinos is a risk factor for disordered gambling. Consequently, casino self-exclusion programs, which provide gamblers with the opportunity to voluntarily seek limits on their access to gambling venues, can serve as a barometer of the concentration of disordered gambling in an area. This study reports on the distribution, both temporally and geographically, of 6,599 people who applied to exclude themselves from Missouri casinos between November, 1996 and February, 2004. Analyses used Microsoft MapPoint to plot the location of casinos and self-excluders (SEs) across Missouri and its constituent counties. These regional exposure analyses showed that the Western region around Kansas City is an epicenter of disordered gambling as, to a lesser extent, is the Eastern region around St. Louis. The annual number of SE enrollments increased during the first few years of the Missouri self-exclusion program and then leveled off during the later years. These findings have important implications for public health and the development of public health interventions for disordered gamblers.     

Self-protection and insurance with interdependencies

We study optimal investment in self-protection of insured individuals when they face interdependencies in the form of potential contamination from others. If individuals cannot coordinate their actions, then the positive externality of investing in self-protection implies that, in equilibrium, individuals underinvest in self-protection. Limiting insurance coverage through deductibles or selling “at-fault” insurance can partially internalize this externality and thereby improve individual and social welfare.

Operations Risk Management: Overview of Paul Kleindorfer's Contributions

This paper reviews Paul Kleindorfer's contributions to Operations Management (OM), with a special focus on his research on risk management. An annotated bibliography of selected other contributions reviews the breadth of topics that have occupied Kleindorfer's research attention over his now 45 + years of research. These include optimal control theory, scheduling theory, decision sciences, investment planning and peak load pricing, plus a number of important applications in network industries and insurance. In the area of operations risk management, we review recent work that Kleindorfer and his colleagues in the Wharton Risk Center have undertaken on environmental management and operations, focusing on process safety and environmental risks in the chemical industry. This work is directly related to Kleindorfer's work in the broader area of “sustainable operations”, which he, Kal Singhal and Luk Van Wassenhove recently surveyed as part of the new initiative at POMS to encompass sustainable management practices within the POMS community. Continuing in the area of supply chain risks, the paper reviews Kleindorfer's contributions to the development of an integrated framework for contracting and risk hedging for supply management. The emphasis on alignment of pricing, performance and risk management in this framework is presaged in the work undertaken by Kleindorfer and his co‐authors in the 1980s on after‐sales support services for high‐technology products. This work on supply chain risk, and its successors, is reviewed here in light of its growing importance in managing the unbundled and global supply chains characteristic of the new economy.
