Polynomial regression analysis and response surface methodology in leadership research

Congruence has served as an important research framework for many leadership research topics. Perhaps the most frequently used methodological/statistical approach for testing the congruence framework is polynomial regression analysis (PRA) with response surface methodology (RSM). As this approach was introduced to organizational sciences more than two decades ago, we can now identify the main issues with the use of this approach in leadership research. To systematically investigate these issues, we first review how PRA and RSM have been used in various leadership studies. We then review the levels-of-analysis and rater model assumptions prevalent in PRA in terms of multilevel techniques, choice of centering options, and issues of endogeneity. Finally, to better understand the inconsistencies and variabilities that exist in leadership research, we review the use of two main RSM features and summarize additional statistical techniques for assessment in this realm. Overall, we aim to promote the rigorousness of this methodology within the study of congruence in leadership research by enhancing its capability in theory testing and building.     

Natural experiments in leadership research: An introduction,review, and guidelines

Endogeneity is a serious challenge for leadership research. To overcome the problem, researchers increasingly rely upon experimental designs, such as laboratory and field experiments. In this paper, we argue that natural experiments — in the form of standard natural experiments, instrumental variable, and regression discontinuity designs — offer additional opportunities to infer causal relationships. We conduct a systematic, cross-disciplinary review of 87 studies that leverage natural experimental designs to inquire into a leadership topic. We introduce the standard natural experiment, instrumental variable, and regression discontinuity design and use topic modeling to analyze which leadership topics have been investigated using natural experimental designs. Based on the review, we provide guidelines that we hope will assist scholars in discovering natural exogenous variations, selecting the most suitable form of natural experiment and by mobilizing appropriate statistical techniques and robustness checks. The paper is addressed to leadership and management scholars who aim to use natural experiments to infer causal relationships.     

Leader behaviors and career derailment potential: A multi-analytic method examination of rating source and self–other agreement

Based on extensive research that views leadership as a multi-faceted phenomenon, we examined how the relationships between task-oriented and relationship-oriented leader behaviors and career derailment potential vary by observer perspective. We present findings using three different analytical techniques: random coefficient modeling (RCM), relative weight analysis (RWA), and polynomial regression (PR). RCM findings suggest that self-, direct report, peer, and supervisor ratings of leader behaviors differ and are associated with career derailment potential. RWA results indicate that self-ratings matter the least, whereas peer ratings of leader behaviors typically matter the most in predicting career derailment potential. PR analyses indicate that career derailment potential is lowest when self-ratings are lower than other ratings of leader behaviors and/or when self–other ratings converge on higher, rather than lower, ratings of leader behaviors. Implications for leadership and self–other agreement research and professional practice are discussed.     

Supply-Chain Strategy: Organizational Influence Through Supplier Alliances

The role of supply-chain management as an integral element in corporate strategy has been discussed in prior research, mostly at a broad conceptual level with relatively little empirical validation. This paper uses data from a longitudinal study of buyer-supplier relationships to evaluate the impact from firms' recent initiatives in developing strategic supplier alliances on the role played by the supply management effort in the corporate hierarchy. Contrary to anticipated results, the use of an alliance approach did not lead to any appreciable improvement in status and respect for supply management's role in developing corporate strategy. While several suggestions are offered to explain these results, the major conceptual models of supply-chain strategy are reassessed and a more appropriate and grounded framework for study is proposed. Further research is called for to empirically verify the link between strategic consideration for supply issues and firm success.     

Testing a longitudinal model of distributed leadership effects on school improvement

A central premise in the literature on leadership highlights its central role in organizational change. In light of the strength of this conceptual association, it is striking to note the paucity of large-scale empirical studies that have investigated how leadership impacts performance improvement in organizations over time. Indeed evidence-based conclusions concerning the impact of leadership on organizational change are drawn largely from case studies and cross-sectional surveys. Neither approach satisfies the design requirements for studying the contribution of leadership to performance improvement in organizations. This paper tests a longitudinal, multilevel model of change in distributed leadership, school improvement capacity, and student performance over a four-year period. The results suggest that change in distributed leadership and organizational capacity for improvement make significant contributions to growth in student learning in reading and math.     

Hierarchical linear modeling as an example for measuring change over time in a leadership development evaluation context

One of the difficulties in evaluating leadership development is measuring whether and how people change over the time period of the leadership development initiative. Even when change over time is an inherent part of the design and evaluation of leadership development, events may occur outside of the control of evaluators that limit the effectiveness of adequately and accurately assessing change over time. With data from a leadership development initiative designed to account for change over time, this article suggests hierarchical linear modeling (HLM) as a multilevel methodological technique to assess change over time in a leadership development context. This article will use real change over time data from a leadership development initiative and discuss the logic and rationale of HLM. We use HLM as an example of a multilevel methodological tool to investigate typical change over time questions in leadership development evaluation.     

Followership theory: A review and research agenda

While theory and research on leaders and leadership abound, followers and followership theory have been given short shrift. It is accepted wisdom that there is no leadership without followers, yet followers are very often left out of the leadership research equation. Fortunately this problem is being addressed in recent research, with more attention being paid to the role of followership in the leadership process. The purpose of this article is to provide a systematic review of the followership literature, and from this review, introduce a broad theory of followership into leadership research. Based on our review, we identify two theoretical frameworks for the study of followership, one from a role-based approach (“reversing the lens”) and one from a constructionist approach (“the leadership process”). These frameworks are used to outline directions for future research. We conclude with a discussion of conceptual and methodological issues in the study of followership theory.     

Applying mixed methods to leadership research: A review of current practices

Leadership research has a long history of a quantitative approach, and it remains the most commonly used approach among leadership researchers. Researchers in a variety of fields have been applying mixed methods designs to their research as a way to advance theory. Mixed methods designs are used for collecting, analyzing, and mixing both quantitative and qualitative data in a single study or series of studies to both explain and explore specific research questions. This article provides a review of the basic characteristics of mixed methods designs. A broad series of leadership approaches is offered to help emphasize how the application of mixed methods designs have already been applied and where they might be directed in future research. Our review of articles published in the Leadership Quarterly between 1990 and June 2012 revealed a slight occurrence of existing application of mixed methods designs to leadership research. Of the articles reviewed, only 15 studies were found to represent mixed methods research, according to our conceptual framework. The overall intent of this article is to highlight the value of purposeful application of mixed methods designs toward advancing leadership theory and/or theoretical thinking about leadership phenomena.     

Putting emergence back in leadership emergence: A dynamic,multilevel, process-oriented framework

The study of leadership emergence has increased substantially over the past few decades. However, due to a lack of integrative theory, we believe limited advancement has been made regarding the full process of leadership emergence. To address this concern, first, we conceptualize the leadership emergence process from a complexity perspective and define emergence as a dynamic, interactive process grounded in three principles of emergent phenomena. Second, we review how previous research has modeled leadership emergence by focusing on the content areas of the lower-level elements, the mechanisms that facilitate their emergence, and the dynamism of the process once it has emerged. Third, based on the findings from the review, we introduce a process-oriented framework of leadership emergence. Fourth, we offer propositions to guide developing and testing emergent leadership processes, and we conclude with recommendations for future leadership process research. Our hope is that by realigning the study of leadership emergence with complexity and multilevel theory, we can reorient this area to focusing more on the process mechanisms within emergence, connecting back to research progress made over 60?years ago.     

Assessing global leadership competencies: the critical role of assessment centre methodology

The purpose of this conceptual paper is to examine the use of assessment centre (AC) methodology for addressing the ever-increasing demand for effective talent management of global leaders. Research is reviewed on the most commonly used questionnaire tools for assessing global leadership competencies, which lack the AC’s ability to provide behavioural evidence of leadership competency. A literature search is conducted to identify the extent to which scholarly research to date has examined the use of ACs to measure global leadership competencies. Based on the findings from the review of the literature, the authors recommend further exploration of a leadership AC approach as a ‘best practice’ talent management tool for measuring global leadership competencies. A framework is provided for designing ACs to evaluate and provide developmental feedback on the competencies identified as critical for successful leadership performance in an organization’s global environment.     

Advances in leader and leadership development: A review of 25 years of research and theory

The development of effective leaders and leadership behavior is a prominent concern in organizations of all types. We review the theoretical and empirical literature on leader and leadership development published over the past 25 years, primarily focusing on research published in The Leadership Quarterly. Compared to the relatively long history of leadership research and theory, the systematic study of leadership development (broadly defined to also include leader development) has a moderately short history. We examine intrapersonal and interpersonal issues related to the phenomena that develop during the pursuit of effective leadership, describe how development emerges with an emphasis on multi-source or 360-degree feedback processes, review longitudinal studies of leadership development, and investigate methodological and analytical issues in leader and leadership development research. Future research directions to motivate and guide the study of leader and leadership development are also discussed.     

Conceptualizing leadership with respect to its historical–contextual antecedents to power

An attempt is made here to build on the ideas and arguments presented in a recent Leadership Quarterly journal article written by Hunt and Dodge [Leadership Q. Yearly Overview Leadership 11 (2000) 435]. In their article, these authors argue that contemporary leadership researchers tend to neglect the historical–contextual antecedents of the field and as a result are developing many theories that reflect little more than a form of “academic amnesia” and “leadership déjà vu”. The importance of Hunt and Dodge's argument is reinforced through the use here of a form of deconstruction to reveal a lacuna in the leadership literature—the insufficient coverage of power, particularly at what is termed a deep structure level. With the current context of organizational change in mind, this lacuna is shown to have problematic consequences for leadership theory in general. More specifically, the increasing use of dispersed leadership strategies is shown to be particularly problematic. The article proposes a new conceptual framework that begins to address these problems and in so doing provides ideas and challenges for future research in the field.     

A 25-year perspective on levels of analysis in leadership research

The purpose of this article is to present a comprehensive 25-year review of the incorporation of levels of analysis into conceptual and empirical leadership research published within Leadership Quarterly throughout its history. We assessed the population of Leadership Quarterly's research (790 research articles) on four key levels of analysis-based issues: (1) explicit statement of the focal level(s) of analysis; (2) appropriate measurement given level of constructs; (3) use of a multi-level data analysis technique; and, (4) alignment of theory and data. Prior reviews regarding levels of analysis incorporation into leadership research have been limited to major research domains. Results revealed that while both conceptual and empirical articles only explicitly state the focal level of analysis in approximately one-third of the articles, appropriate levels-based measurement and alignment between theory and data are relatively strong areas of achievement for the articles within Leadership Quarterly. Multi-level data analysis techniques are used in less than one-fifth of all articles. Although there is room for improvement, there is evidence that Leadership Quarterly is a premier outlet for levels-based leadership research. Given the increasing complexity of organizational science with regard to groups, teams and collectives, Leadership Quarterly has an opportunity to model for organizational research on how to build and test complicated multi-level theories and models.     

12 Structural Equation Modeling in Management Research: A Guide for Improved Analysis

Abstract

A large segment of management research in recent years has used structural equation modeling (SEM) as an analytical approach that simultaneously combines factor analysis and linear regression models for theory testing. With this approach, latent variables (factors) represent the concepts of a theory, and data from measures (indicators) are used as input for statistical analyses that provide evidence about the relationships among latent variables. This chapter first provides a brief introduction to SEM and its concepts and terminology. We then discuss four issues related to the measurement component of such models, including how indicators are developed, types of relationships between indicators and latent variables, approaches for multidimensional constructs, and analyses needed when data from multiple time points or multiple groups are examined. In our second major section, we focus on six issues related to the structural component of structural equation models, including how to examine mediation and moderation, dealing with longitudinal and multilevel data, issues related to the use of control variables, and judging the adequacy of models and latent variable relationships. We conclude with a set of recommendations for how future applications of SEM in management research can be improved.     

Mapping and managing productive organizational energy over time: The Energy Pattern Explorer tool

To strategically manage the deployment of collective human resources toward performance, managers must recognize, interpret, and align the volatile resources of productive organizational energy. Despite relevant prior work, research and practice still lack a comprehensive approach toward analyzing and managing energy patterns over time. We develop a framework for temporal configurations and prototypical trajectories of productive organizational energy. We then introduce the ‘Energy Pattern Explorer’ as a strategy tool to: (1) identify and predict actual patterns of productive organizational energy in organizations, and (2) suggest energy leadership activities specific to current and anticipated changes and patterns of productive organizational energy. We provide examples of how managers can use this tool and conclude with suggestions for research and practice.     

Causal Linkages in Supply Chain Management: An Exploratory Study of North American Manufacturing Firms

In this paper we investigate the key causal linkages in supply chain management. We propose a conceptual framework and test this framework on data from 215 North American manufacturing firms using structural equation modeling techniques. Three major research issues are addressed in this study: Do sourcing decisions affect the degree to which firms achieve manufacturing goals of cost, flexibility, dependability, and quality? Does the degree of manufacturing goal achievement lead to higher customer responsiveness? Does the degree of manufacturing goal achievement lead to higher internal manufacturing performance? The study examines the relationship among sourcing decisions, manufacturing goals, customer responsiveness, and manufacturing performance. The results support the notion that an integrated supply chain involves aligning sourcing decisions to achieve manufacturing goals that are set to respond favorably to the needs of customers.     

Just how multi-level is leadership research? A document co-citation analysis 1980–2013 on leadership constructs and outcomes

The use of multi-level theories and methodologies in leadership has gained momentum in recent years. However, the leadership field still suffers from a fragmented and unclear evolution and practice of multi-level approaches. The questions of how and to what extent multi-level research has evolved in both leadership phenomena and leadership outcomes, and which informal research networks drove this evolution, remain vastly unexplored. In this study, the extent of literature published between 1980 and 2013 is analyzed using a document co-citation analysis and invisible colleges' framework. This allows us to map the evolution of the multi-level intellectual structure of the leadership field. Specifically, we identify a number of distinct colleges – their conceptualization of leadership and outcomes – and trace their evolution paths over thirty years. We find a considerable fragmentation of the field, with the usage of multi-level leadership conceptualization mostly embraced by more peripheral clusters. Finally we discuss implications for further research with regard to a set of distinct trajectories for the future evolution of multi-level approaches in the leadership domain.

On studying leadership in the strategy field

This article is primarily concerned with the study of leadership in the strategy field. It argues that as our perspective on the strategy process itself changes so too must our perspective on top leadership and our approaches to studying it. From a review of the literature the article identifies some of the current issues and challenges in studying leadership and strategy and argues for more dynamic and contextually-sensitive approaches than those that have dominated up to now. It presents and develops a framework for the future study of leadership based on three main foundations: Mintzberg's (1978) concept of strategy formation, Pettigrew's (1985) contextualism, and the author's empirical studies to date. The framework focuses on the process of leadership and its role within the more inclusive process of strategy formation. This process-within-a-process perspective, it is argued, potentially opens the way to gaining fresh perspective on leadership by inviting attention to such underexplored issues as how and why leadership effectiveness varies with time and context, how the symbolic and substantive aspects of leadership interact to produce outcomes of strategic significance, and how successive leaders and their tenures are connected in the strategy formation process over time. At a time when the field of sociology is showing an increasing interest in the concept of strategy, there appears to be great scope for a more serious infusion of the sociological perspective in the opposite direction, and frameworks, such as the one presented in this paper, may help to get such a movement underway.     

An evaluation of conceptual weaknesses in transformational and charismatic leadership theories

Theories of transformational and charismatic leadership provide important insights about the nature of effective leadership. However, most of the theories have conceptual weaknesses that reduce their capacity to explain effective leadership. The conceptual weaknesses are identified here and refinements are suggested. The issue of compatibility between transformational and charismatic leadership is also discussed. Finally, some methodological problems involving construct validation and theory testing are identified, and suggestions for future research are provided.
