Coopetitive Buyer–Supplier Relationship: An Investigation of Bargaining Power,Relational Context,and Investment Strategies

This study proposes an analytical approach combined with a behavioral experiment for a joint examination of the competitive and cooperative (i.e., coopetitive) relationship between a buyer and a supplier. Specifically, the article considers the scenario in which the buyer and the supplier invest in strategic capabilities to increase their relative bargaining power. The article examines how dynamic investments in strategic assets are influenced by the locus of bargaining power and by the underlying context (synergistic vs. adversarial) of the interfirm relationship. The dynamic evolution of bargaining power is also examined. A dynamic game model is considered to examine the evolution of investment strategies in critical resources and to investigate the issues of bargaining power in a buyer–supplier dyad. Equilibrium expressions for the investment strategies of the buyer and the supplier are presented and their implications for buyer–supplier relationships are examined. The behavioral experiment complements the analytical model and examines the correspondence between optimal behavior suggested by the analytical model and the boundedly rational behavior of decision makers in an experimental context. The results from the model and behavioral experiments suggest that the strategies are a function of the risk‐adjusted returns obtained from investments. The experiment shows that, in a synergistic relational context when the buyer maintains bargaining power, the investment shifts of the buyer and the supplier accord well with theoretical predictions. In an adversarial relational context, the results of the experimental study do not correspond well with that predicted by the theoretical model. The implications of the results are discussed and directions for future research are presented.     

Multilevel Social Dynamics Considerations for Project Management Decision Makers: Antecedents and Implications of Group Member Tie Development

Successful projects represent the effective culmination of management skills, planning, and individual project member strengths. In operations management, such strengths are often viewed predominantly from the perspective of skill base. However, it has become increasingly evident that behavioral traits associated with individuals play a very significant, if not ultimately dominating, role in the effectiveness of certain group projects. Our aim in this study is to look into how certain individual attributes viewed as relevant to these project contexts may lead to social networking decisions that have impacts spanning multiple levels of analysis. Such insights are likely to prove valuable to decision makers managing project teams as well. We employ a controlled 4‐month investigation of multiple projects, for which we are able to consider both objective, and subjective pre‐, in situ, and postproject data. Our results demonstrate that the issues of perceived control, confidence, and conscientiousness are relevant not only in driving individual perceptions of the value of within‐group interactions, and hence the development of associated ties, but are also ultimately relevant in helping to drive higher levels of group performance.     

Bodies of Knowledge for Research in Behavioral Operations

Whenever intrepid researchers venture into new terrain, they find that they require knowledge outside of their formal training. This paper reviews bodies of knowledge for operations management (OM) researchers interested in the new area of Behavioral Operations. We highlight theoretical constructs and empirical phenomena from cognitive psychology, social psychology, group dynamics, and system dynamics. We also provide a guide for where to go to learn more about each body of knowledge. Our overall goal is to lower the startup costs for new researchers in Behavioral Operations.     

A modified least-failures sampling procedure for bernoulli subset selection

We restrict attention to a class of Bernoulli subset selection procedures which take observations one-at-a-time and can be compared directly to the Gupta-Sobel single-stage procedure. For the criterion of minimizing the expected total number of observations required to terminate experimentation, we show that optimal sampling rules within this class are not of practical interest. We thus turn to procedures which, although not optimal, exhibit desirable behavior with regard to this criterion. A procedure which employs a modification of the so-called least-failures sampling rule is proposed, and is shown to possess many desirable properties among a restricted class of Bernoulli subset selection procedures. Within this class, it is optimal for minimizing the number of observations taken from populations excluded from consideration following a subset selection experiment, and asymptotically optimal for minimizing the expected total number of observations required. In addition, it can result in substantial savings in the expected total num¬ber of observations required as compared to a single-stage procedure, thus it may be de¬sirable to a practitioner if sampling is costly or the sample size is limited.     

Correlates and Predictors of Lottery Play in the United Kingdom

Previous studies of lottery play have tended to adopt one particular approach, concentrating on demographic, personality, cognitive, or social aspects of play. Using the recently introduced United Kingdom National Lottery, this study investigated variables associated with all of these approaches within an overall integrative framework. In a community sample (N = 160), Lottery play was positively correlated with friends' Lottery play, Instants Lottery play, frequency of other gambling, and misunderstanding of Lottery probability, and negatively correlated with level of education. In a regression analysis, friends' Lottery play, Instants Lottery play, and education level were significant unique predictors of Lottery play, and a combination of these and other variables accounted for 38% of the variance in playing behavior. The results are discussed predominantly in terms of the nature of lotteries as a social activity.     

Developing a program for social work with Latino populations: a case study

ABSTRACT

This paper presents a case study of the development of a program in a large U.S. School of Social Work to train social work students to work with Latina/o populations entitled ‘Latino/a Initiatives for Service, Training, and Assessment’ (LISTA). Using a case study methodology, this work fills a current gap in the literature as it examines the programmatic and curricular dynamics associated with such an effort. The methods section details LISTA’s planning process and early implementation. This includes the demographic, theoretical, and professional context of the program along with the stages of curricular development. The results section examines LISTA’s current curriculum, including three courses, field placements and study abroad program, as well as its assessment processes. It further examines issues and challenges related to developing a new curricular emphasis in a graduate program, including funding, recruitment, and securing field placements. The discussion section provides a set of recommendations, including the institutionalization of mechanisms for community feedback and the recruitment of ethnic minority students and faculty. LISTA serves as a potential model for recruiting and training social workers to serve diverse ethnic minority populations.     

Casting a Wide Net for Innovation: Mediating Effect of R&D Human and Social Capital to Unlock the Value from Alliance Portfolio Diversity

This paper examines the performance effects associated with different alliance portfolio configurations in terms of geographical location and partner type. Based on these distinctions, the authors hypothesize that more diverse alliance portfolios enable firms to gain and exploit innovation opportunities. Additionally, the mediating effects of R&D human and social capital on the R&D alliance portfolio diversity–innovation performance relationship are explored. The authors reason that the absorptive capacity of R&D intellectual capital determines a firm's potential gains from highly diverse alliance portfolios. From panel data of manufacturing firms in Spain for the period 2008–2013, the results confirm the inverted U‐shaped relationship between alliance portfolio diversity and firm innovation performance, implying that both insufficient and excessive alliance portfolio diversity may be detrimental to firm innovativeness. Additionally, R&D human and social capital partially mediates the R&D alliance diversity–innovation performance relationship, emphasizing the importance of internal capabilities to leverage the benefits of highly diverse alliance portfolios. These findings add a dynamic dimension to the conceptualization of alliance portfolios and how firms create value by balancing explorative and exploitative alliances.     

Buying and selling breasts: cosmetic surgery,beauty treatments and risk

This paper is concerned with the ways in which women are sold cosmetic surgery, and how they ‘make sense of’ their own participation in this market. It draws on ongoing ethnographic research to explore how a group of young women who have paid for breast augmentation surgery narrate their decision to undergo surgery, the choices they make as consumers of cosmetic surgery, and their experience of having surgery. These narratives are compared with the ways in which breast augmentation surgery is sold to them by the companies and medical professionals involved in the rapidly expanding market for breast augmentation surgery. The paper shows how this particular group of young white working‐class women shift between imagining the breast augmentation operation as a simple beauty treatment and recognizing it as medical surgery, and explores how this shapes their perceptions of the risks and benefits of buying new breasts. It also shows how those who market such procedures manage and manipulate perceptions of the process of breast augmentation surgery and the risks that attend on it in an effort to encourage this form of consumption.     

Bounding Estimates for Critical Events When Directly Disposing Highly Enriched Spent Nuclear Fuel in Unsaturated Tuff

This paper examines the possibility of criticality in a nuclear waste repository. The estimated probabilities are rough bounds and do not entirely dismiss the possibility of a critical condition; however, they do point to the difficulty of creating conditions under which a critical mass could be assembled (i.e., corrosion of containers, separation of neutron absorbers from the fissile material, and collapse or precipitation of the fissile material). In addition, should a criticality occur in or near a container, the bounding consequence calculations showed that fissions from one critical event are quite small (<˜10²⁰ fissions, if similar to aqueous and metal accidents and experiments). Furthermore, a reasonable upper bound of total critical events of 10²⁸ fissions corresponds to only 0.1% of the number of fissions represented by the spent nuclear fuel inventory in a repository containing 70,000 metric tons of heavy metal (MTHM) (the expected size for the proposed repository at Yucca Mountain, Nevada).
