Industry, corporate, and segment effects and business performance: a non‐parametric approach

Abstract: The literature investigating the degree to which firm performance is associated with industry or corporate factors has recently been subject to criticism on the grounds of both methodological shortcomings and incomplete interpretation of results. Our research goes beyond these critiques to raise more basic issues concerning the assumptions underlying variance decomposition, the methodology dominating the antecedent literature. Performance data and categorizations from a sample consistent with those employed in the recent literature are analyzed via a new non-parametric methodology. Results here indicate that corporate factors were over an order of magnitude better predictors of business unit profit position than were industry factors—which were found not to have been significant predictors. Further, underlying performance relationships were seen to have shifted over time. A key implication of these results for researchers is that they provide additional evidence that managers can have a strategic influence on business performance.

A polynomial of graphs on surfaces

Abstract: , i.e., graphs realized as disks (vertices) joined together by strips (edges) glued to their boundaries, corresponding to neighbourhoods of graphs embedded into surfaces. We construct a four-variable polynomial invariant of these objects, the ribbon graph polynomial, which has all the main properties of the Tutte polynomial. Although the ribbon graph polynomial extends the Tutte polynomial, its definition is very different, and it depends on the topological structure in an essential way.

Service Worker Burnout and Turnover Intentions: Roles of Person-Job Fit, Servant Leadership, and Customer Orientation

Abstract: This study examines the effects of customer orientation and servant leadership on frontline employees' burnout and, subsequently, on their turnover intentions. Also investigated in the study is the intervening role of person-job fit in the process. Data collected from 530 frontline bank employees in New Zealand serve as the study setting. Results show that both customer orientation and servant leadership significantly reduce burnout and ultimately turnover intentions. Results also show that person-job fit mediates the influences of customer orientation and servant leadership on burnout and turnover intentions. Implications of the results are discussed and future research avenues are offered.
