Buyer Perceptions of Supply Disruption Risk: A Behavioral View and Empirical Assessment

As supply chains become more complex, firms face increasing risks of supply disruptions. The process through which buyers make decisions in the face of these risks, however, has not been explored. Despite research highlighting the importance of behavioral approaches to risk, there is limited research that applies these views of risk in the supply chain literature. This paper addresses this gap by drawing on behavioral risk theory to investigate the causal relationships amongst situation, representations of risk, and decision-making within the purchasing domain. We operationalize and explore the relationship between three representations of supply disruption risk: magnitude of supply disruption, probability of supply disruption, and overall supply disruption risk. Additionally, we draw on exchange theories to identify product and market factors that impact buyers’ perceptions of the probability and magnitude of supply disruption. Finally, we look at how representations of risk affect the decision to seek alternative sources of supply. We test our model using data collected from 223 purchasing managers and buyers of direct materials. Our results show that both the probability and the magnitude of supply disruption are important to buyers’ overall perceptions of supply disruption risk. We also find that product and market situational factors impact perceptions of risk, but they are best understood through their impact on perceptions of probability and magnitude. Finally, we find that decisions are based on assessments of overall risk. These findings provide insight into the decision-making process and show that all three representations of risk are necessary for fully understanding risky decision-making with respect to supply disruptions

Making Sense Of Supply Disruption Risk Research: A Conceptual Framework Grounded In Enactment Theory

The rich stream of supply disruption risk (SDR) literature incorporates several different theories and constructs across studies, but lacks a unifying decision-making framework. We review 79 SDR studies and advance a comprehensive framework, grounded in enactment theory, which integrates the disparate elements of SDR research and offers new insights into the SDR decision-making process. Enactment theory posits a three-stage, closed-loop process, consisting of enactment, selection and retention, through which individuals process and make sense of equivocal environments. We suggest that this sense-making process also underlies SDR decision-making, and provides the theoretical underpinnings for the environmental, organizational and individual factors that affect the formation of buyers\u27 perceptions of SDR and the actions they take to mitigate such risks. In accordance with our conceptual framework, we develop seven propositions that advance the social and psychological factors that drive the idiosyncratic nature of SDR decision-making

Supply chain organizational infrastructure for promoting entrepreneurial emphasis and innovativeness: The role of trust and learning.

Research has argued that inter-organizational trust and learning are critical factors associated with successful supply chain innovation and long-term competitiveness. In this paper, we develop and test a proposed model of supply chain organizational design using survey data collected from 128 decision-makers across diverse sample of supply chain decision-makers across many industries. Our analysis provides evidence that both trust and supply chain learning play important, but distinctive roles in developing an entrepreneurial and innovative supply chains. Moreover, our research findings add critical insight into existing resource-based perspectives of supply chain innovation by illuminating the roles and progression of the different resource elements – trust, supply chain learning, entrepreneurial emphasis, innovativeness – in developing and building a competitive supply chain infrastructure

Doctoral Candidate Operations and Supply Chain Management Group

The purpose of my research is to develop and empirically test a comprehensive theory of retail service design strategies. This theory will focus on the impact of physical channel design strategies on merchandise retailer effectiveness, measured in terms of satisfaction, operating, and long-term market performance. To develop this theory, I draw from a multidisciplinary literature base including organizational design, service operations management and strategy, economics, information systems, consumer marketing, and studies analyzing capital markets. This theory will enlighten future academic research and provide retail managers and store designers a method to weigh the tradeoffs associated with well-established physical channel design strategies. Retailers can test the “fit ” of key design choices based on 1) retail environmental and information uncertainty and 2) firm operating and financial performance measures. Towards this end, my dissertation research develops three essays to address gaps in the extant service operations literature with respect to retail design strategies that focus on customer encounters 1 and environmental uncertainty. In these essays, I use a combination of empirical methods, including survey and econometric data analysis techniques, to address these issues. A first step in good empirical science is the development of reliable and valid measures that tap into salient constructs associated with th

Start over and survive: A brief intervention for substance misuse in early psychosis

Over the last decade, brief intervention for alcohol problems has become a well-validated and accepted treatment, with bried interventions frequently showing equivalence in terms of outcome to more extended treatments (Bien et al, 1993). A recent review of this studies found that heavy drinkers who received interventions of less than 1 h were almost twice as likely to moderate their drinking over the following 6-12 months as did those not receiving intervention (Wilk etal, 1997).Some studies have used motivational interviewing (MI) strategies (Monti et al, 1999); others have simply given information ajnd advice to reduce drinking (Fleming et al, 1997). Leaflets or information on strategies to assist in the attempt or follow-up sessions are sometimes provided (Fleming et al, 1997). In general practice research, provision of one or more follow-up sessions increases the reliability of intake reductions across studies (Poikolainen, 1999)

A brief motivational intervention for substance misuse in recent-onset psychosis

Substance misuse is common in early psychosis, and impacts negatively on outcomes. Little is known about effective interventions for this population. We report a pilot study of brief intervention for substance misuse in early psychosis (Start Over and Survive: SOS), comparing it with Standard Care (SC). Twenty-five in-patients aged 18-35 years with early psychosis and current misuse of non-opioid drugs were allocated randomly to conditions. Substance use and related problems were assessed at baseline, 6 weeks and 3, 6 and 12 months. Final assessments were blind to condition. All 13 SOS participants who proceeded to motivational interviewing reported less substance use at 6 months, compared with 58% (7/12) in SC alone. Effects were well maintained to 12 months. However, more SOS participants lived with a relative or partner, and this also was associated with better outcomes. Engagement remained challenging: 39% (16/41) declined participation and 38% (5/13) in SOS only received rapport building. Further research will increase sample size, and address both engagement and potential confounds

A Social Network Analysis of the Western Journal of Emergency Medicine Special Issue in Educational Research and Practice.

INTRODUCTION: Scholarship and academic networking are essential for promotion and productivity. To develop education scholarship, the Council of Emergency Medicine Directors (CORD) and Clerkship Directors of Emergency Medicine (CDEM) created an annual Special Issue in Educational Research and Practice of the Western Journal of Emergency Medicine. The objective of this study was to evaluate the network created by the special Issue, and explore changes within the network over time. METHODS: Researchers used bibliometric data from Web of Science to create a social network analysis of institutions publishing in the first four years of the special issue using UCINET software. We analyzed whole-network and node-level metrics to describe variations and changes within the network. RESULTS: One hundred and three (56%) Accreditation Council for Graduate Medical Education-accredited emergency medicine programs were involved in 136 articles. The majority of institutions published in one or two issues. Nearly 25% published in three or four issues. The network analysis demonstrated that the mean number of connections per institution increased over the four years (mean of 5.34; standard deviation [SD] 1.27). Mean degree centralization was low at 0.28 (SD 0.05). Network density was low (mean of 0.09; SD 0.01) with little change across four issues. Five institutions scored consistently high in betweenness centrality, demonstrating a role as connectors between institutions within the network and the potential to connect new members to the network. CONCLUSION: Network-wide metrics describe a consistently low-density network with decreasing degree centralization over four years. A small number of institutions within the network were persistently key players in the network. These data indicate that, aside from core institutions that publish together, the network is not widely connected. There is evidence that new institutions are coming into the network, but they are not necessarily connected to the core publishing groups. There may be opportunities to intentionally increase connections across the network and create new connections between traditionally high-performing institutions and newer members of the network. Through informal discussions with authors from high-performing institutions, there are specific behaviors that departments may use to promote education scholarship and forge these new connections
