A Bootstrap Approach for Testing Marginal Independence Between Two Categorical Variables When Subjects Have Repeated Responses

To assess independence in two-way contingency tables, the Pearson chi-square test or Fisher’s exact test are typically used. These tests assume that each subject contributes at most one count to only one table cell (e.g., sex versus blood type). In other situations, each subject may have more than one count contributing to the table and these counts may occur in different cells of the table. One may wish to test independence, adjusting for the within-subject correlation. We provide a simple nonparametric bootstrap approach and assess its performance through simulation studies. The method is illustrated on subjects with multiple mental health presentations to Emergency Departments.     

The Differential and Contingent Impact of Concurrency on New Product Development Project Performance: A Holistic Examination*

This article comprehensively examines how the four facets of new product development (NPD) concurrency, consisting of process and product concurrency groupings, influence NPD project performance under the five contextual conditions of (i) location of product in family stream, (ii) project size, (iii) stage in the product life cycle, (iv) innovativeness of the product, and (v) predictability of market demand. Using data from a large sample of NPD projects in multiple industries, there is support for this hypothesized four‐faceted structure of concurrency, consisting of process and product concurrency groupings, thereby contributing new knowledge to the concurrency literature. All four facets of concurrency display a contingent impact on NPD project performance, even though individual effects vary according to the specific contextual variable under consideration. In particular, the process concurrency facet of dynamic iterative routines was universally effective across all five contextual variables, while the product concurrency facet of cross‐functional coordination was effective in significantly influencing at least one NPD project measure. This article also reports similar, but less strong, contingency patterns, with respect to the process concurrency facet of the implementation of downstream coordination and the product concurrency facet of the use of computer‐based integrated design tools. Theoretical and practical implications of our results are also offered.     

Contingency tables with structural zeros

In this paper, the method of Hocking and Oxspring (1971) to estimate multinomial probabilities when full and partial data are available for some cells is extended to estimate the cell probabilities of a contingency table with structural zeros. The estimates are maximum likelihood, and the process is sequential. The gain in precision is due to the use of partial data and the bias of the estimates is also investigated.     

In Memoriam: Frank Wilcoxon

A mosaic is a graphical display of cross-classified data in which each count is represented by a rectangle of area proportional to the count. The positions and sides of the rectangles are set to encourage comparisons between counts in the figures. Mosaics are useful for discovering unusually high or small counts and for discovering dependencies between variables. In principle, mosaics may be used for any number of cross-classifying variables, but six seems to be a practical maximum. A mosaic is given for a four-way classification of Nielsen ratings.     

Identifying key influencers of Chinese PR practitioners’ strategic conflict management practice: A survey on contingent variables in Chinese context

As the first quantitative test of contingency theory in China using an online survey, this study examined the influence of each of the over 80 individual contingent variables as perceived by Chinese public relations practitioners. Individual characteristics as related to conflict management as well as political–social factors were identified as the most influential variables. By forming influential contingent factors and exploring the dimensionality of these factors using factor analysis, the results of this study suggested structural stability of the contingency matrix. Further, the effects of gender and types of organizations were tested on how Chinese practitioners perceive these influences in their public relations practice. The findings provide insights for both practitioners and researchers on how to strategically identify and combine the most influential factors in effective and ethical conflict management in China.     

Still fighting the good fight: An analysis of student activism and institutional response

The current study employs content analysis of news coverage on recent campus protests (the University of Missouri, the University of Cincinnati, Harvard School of Law, and Ithaca College). Using the contingency theory of conflict management as a theoretical framework, the study sought both parties’ (institution and student activist group) stances along the continuum of pure advocacy to pure accommodation. The study also examined whether recent student groups applied radical activist strategies, and if institutions employed conflict resolution strategies.Results indicate both parties were advocating, with only institutions moving along the continuum from advocacy to pure accommodation. Students were found to execute radical activist strategies and institutions’ responses were dominantly unconditionally constructive.     

Looking back,moving forward: A review and reflection of the organization-public relationship (OPR) research

Organization-Public Relationship (OPR), as a key concept addressed in the field of public relations has attracted wide attention in the past three decades. This study presents a comprehensive review of 156 relevant studies from 1998 to 2016 and categorizes them into five main clusters, which include the outcomes, antecedents, mediation, process, and structure of OPR. Findings also identify five gaps in current OPR research such as idealized propositions based on mutual benefits, a lack of research on multi-party relationships, problematic “trust” as the measurement, unilateral self-reported research data, and dominated cross-sectional methods By drawing contingency theory of accommodation and the relationship management theory, this study proposes the concept of contingent organization-public relationship (COPR) for future studies that seek to explore variations of OPR longitudinally.     

Knowledge Management Using Information Technology: Determinants of Short‐Term Impact on Firm Value*

The importance of knowledge management (KM) processes for organizational performance is now well recognized. Seeking to better understand the short‐term impact of KM on firm value, this article focuses on public announcements of information technology (IT)‐based KM efforts, and uses cumulative abnormal return (CAR) associated with an announcement as the dependent variable. This article employs a contingency approach, arguing that the KM announcement would have a positive short‐term impact on firm value in some conditions but not in others. Thus, it pursues the following research question: What are the effects of contextual factors on the CAR associated with the announcement of an IT‐based KM effort? Specific hypotheses are proposed based on information‐processing theory, organizational learning theory, the knowledge‐based theory of the firm, and the theory of knowledge creation. These hypotheses link CARs to alignment between industry innovativeness and the KM process, alignment between firm efficiency and the KM process, firm‐specific instability, and firm diversification. The empirical study utilizes secondary data on 89 KM announcements from 1995 to 2002. The results largely support the hypotheses. Overall, this article provides empirical support for the theory‐based arguments, and helps develop a contingency framework of the effectiveness of KM efforts.     

The estimation of a corporate crisis communication

This experimental study found a main effect of perceived leadership and an interaction effect of perceived leadership and perceived severity of threats on the public's estimation of organizational crisis responses. The results indicate that the contingent theoretical argument explaining the dynamics of organizational factors and situational factors that determine stance taken by public relations practices can also be applied when explaining the outside latent public's thought patterns predicting an organizational stance and message strategy. Contingency theory offers predictive power, not just for the practitioner, but for the public passing judgment on the stance taken by an organization.     

Does merger & acquisition (M&A) strategy matter? A contingency perspective

This paper takes a contingency approach to investigate whether there are market performance variations for different types of M&A. Eight different types of M&A are identified in a typology based upon the conjunction of three contextual dimensions: external environmental, acquiring firm level strategy and CEO motivation. Drawing upon a sample of 1,926 domestic UK deals we evaluate the typology to determine whether the financial markets distinguish between different types of M&A. Results indicate significant market and risk-adjusted performance differences by M&A type. These confirm that a contingency approach to M&A performance has merit. We suggest that the proposed integrated typology, that recognizes the importance of multiple aspects of strategic fit to M&A performance, addresses the paradox that M&A practitioners continue to pursue deals despite widespread acceptance that they result in high failure rates.
