The purpose of this chapter is to provide researchers a summary of some of the latest developments in item response theory (IRT), and to help these groups realize that psychometric tools can now be used for theory testing in addition to the traditional role of improving construct measurement. The author first reviews some of the fundamental tenets of classical test theory to contrast with IRT. He then describes recent advances in goodness-of-fit tests that have helped turn IRT into a model-testing tool. Finally, the author reviews several new test models that provide new flexibilities, summarizing summarize several examples of research that has used these new models in organizational research. At the end of this review, the author provides suggestions to help researchers better use these new IRT tools. Although there have been significant advances in IRT in the past decade, there has not been a systematic review of these developments. This review places those developments in context to provide readers a real appreciation of these breakthroughs.

Multidimensional fit (MDF) has been coined as “elusive” and relevant to an individual’s social identity and self-concept, unfolding over time as individuals assess their fit relative to Person-Organization, Person-Vocation, Person-Job, and Person-Team Fit. In this chapter, the literature as it relates to the refugee employment journey, MDF, and HRM practices that facilitate or inhibit MDF is reviewed. Furthermore, in this study, the process-oriented view of the refuge path highlights the complexity of their experience, noting an array of antecedents as they relate to country, host country and individual differences, interventions through NGOs, refugee resettlement agencies, and organizations, as well as the less explored entrepreneurial path. These diverse paths and the process of finding fit, and the obstacles refugees face, are viewed through the lens of shocks and reassessment of MDF throughout their journey. Finally, the study’s outcomes illustrate individual wellbeing factors, organizational level benefits, as well as community level benefits to MDF.

This chapter applies three of the most prominent theories in vocational and career psychology to further illuminate the turnover process. Prevailing theories about attrition have rarely integrated explanatory constructs from vocational research, though career (and job) choices clearly have implications for employee affect and loyalty to a chosen job in a career field. Despite remarkable inroads by new perspectives for explaining turnover, career, and vocational formulations can nonetheless enrich these – and conventional – formulations about why incumbents stay or leave their jobs. To illustrate, vocational theories can help clarify why certain shocks (critical events precipitating thoughts of leaving) drive attrition and what embeds incumbents. In particular, this chapter reviews Super's life-span career theory, Holland's career model, and social cognitive career theory and describes how they can fill in theoretical gaps in the understanding of organizational withdrawal.

This paper develops a comprehensive multidimensional legitimacy model that provides a generic framework for exploring legitimacy in institutions – including the legitimacy of rules, codes, collective activities and organisations themselves. Through the use of 10 dimensions, covering concerns with fairness, efficacy, integrity, expectations, inclusive decision-making and more, the model aims to capture the full suite of distinct features that may be morally relevant in any given case. Each dimension is a continuum and can provide reasons for moral challenge, toleration or pro-active support. The model can be used to diagnose ethical risk areas, to compare reform initiatives and to inform empirical studies of descriptive legitimacy and the social licence to operate. It may also be used as an applied ethics methodology to evaluate overall institutional moral legitimacy; the paper discusses the contextual judgments required for this, including the way that some legitimacy factors can operate as defeaters, such that a serious failure on a pivotal dimension cannot be overcome by support from other dimensions.

“Fit” as a human resources decision criterion has emerged as an active body of research in recent years, but its “elusiveness” as a scientific construct, noted more than a decade ago by Judge and Ferris, still remains. To best address this issue, this chapter proposes an integrative theory of multidimensional fit that encompasses five relevant (and distinct) streams of current fit research: Person-Organization Fit, Person-Vocation Fit, Person-Job Fit, Person-Preferences for Culture Fit, and Person-Team Fit. It is proposed that these five dimensions of fit relate to an individual's self-concept; moreover, an individual assesses multidimensional fit utilizing a social cognitive decision-making process called prototype matching. By assessing fit across multiple dimensions, an individual can both gain a social identity and expand the self-concept, which explains the motive to fit. Testable propositions are formulated, and implications for multidimensional fit across the employment lifecycle are discussed. Furthermore, directions for future fit research are provided.

Entrepreneurial orientation (EO) has emerged as a core concept in the field of entrepreneurship. Yet, there continue to be questions about the nature of EO and how best to conceptualize and measure it. This chapter makes the case that EO has grown beyond its roots as a firm-level unidimensional strategy construct and that a new multidimensional version of EO is needed to capture the diverse manifestations and venues for entrepreneurial activity that are now evident around the world – global entrepreneurial orientation (GEO). Building on the five-dimension multidimensional view of EO set forth when Lumpkin and Dess (1996) extended the work of Miller (1983) and Covin and Slevin (1989, 1991), the chapter offers an updated definition of EO and a fresh interpretation of why EO matters theoretically. Despite earnest efforts to reconcile the different approaches to EO, in order to move the study of EO and the theoretical conversation about it forward, we maintain that as a group of scholars and a field, we need to acknowledge that two different versions of EO have emerged. Given that, we consider original approaches to measuring EO, evaluate formative measurement models, consider multiple levels of analysis, call for renewed attention to EO configurations, and discuss whether there is a theory of EO.

In this chapter, we summarize and build on the current state of the customer mistreatment literature in an effort to further future research on this topic. First, we detail the four primary conceptualizations of customer mistreatment. Second, we present a multilevel model of customer mistreatment, which distinguishes between the unfolding processes at the individual employee level and the service encounter level. In particular, we consider the antecedents and outcomes unique to each level of analysis as well as mediators and moderators. Finally, we discuss important methodological concerns and recommendations for future research.
