Incorporating social networks into leadership development: A conceptual model and evaluation of research and practice

Multilevel and relational views of leadership are expanding the focus of leadership development beyond individuals' knowledge, skills, and abilities to include the networked patterns of social relationships linking members of dyads and larger collectives. In this review, we present a conceptual model explaining how three distinct approaches for network-enhancing leadership development can improve the leadership capacity of individuals and collectives. We then present a review of the leadership development literature and the results of a survey of 282 practitioners to assess the extent to which these approaches have been examined in research and implemented in practice. Our review revealed that leadership research and leadership development practice are outpacing leadership development research in terms of incorporating networks. We aim to spur future research by clarifying the targets, objectives, and underlying mechanisms of each network enhancing leadership development approach in our conceptual model. Further, we identify additional literature, not traditionally considered within the realm of leadership development that may help advance empirical examinations of these approaches.     

The enactment of plural leadership in a health and social care network: The influence of institutional context

In this article we employ developments in social network analysis (SNA), specifically the p* model, to examine the enactment of plural leadership within, and across, hierarchical levels and organizational boundaries (Denis et al., 2012). Drawing on an empirical study of an inter-professional, inter-organizational network (number of nodes = 23) that delivers health and social care, we address two research gaps: (i) the effect of power relations, derived from professional hierarchy, upon spread of plural leadership; and (ii) the effect of formal leadership, derived from managerial accountability, in channeling the spread of plural leadership for coherent strategic effect. We show that, in a routine situation, the network is characterized by generalized leadership exchanges. In this situation, professional hierarchy and managerial accountability are not visible, nor is channeling of plural leadership by the formal leader. In a non-routine situation, when a disruptive event occurs, the network is characterized by restricted exchange. In this situation, professional hierarchy and managerial accountability are evident, and a formal leader channels plural leadership.     

Pushing up to a point: Assertiveness and effectiveness in leadership and interpersonal dynamics

Past work on interpersonal assertiveness and organizational effectiveness paints a mixed picture: some research suggests a positive link, other work highlights negative effects. This article reviews recent research and an account that stems from a different perspective, looking at assertiveness as a factor in leadership shortcomings and failure. This approach suggests that interpersonal assertiveness is a major factor and has a curvilinear, inverted-U-shaped relationship with leadership effectiveness. I review evidence for this effect as well as social and instrumental outcome mediators. I consider moderators and boundaries, sources of individual differences in assertive behavior, prospects for changing assertiveness, and factors in the perception of assertive behavior. Beyond the specific results I review, I argue that this program of work offers value by highlighting the lens of conflict as a generative perspective on leadership. Exploring how, and how hard, leaders fight pulls in insights from a variety of literatures and prompts new research that can help expand the scholarly portrait of leadership.     

Scholarly leadership of the study of leadership: A review of The Leadership Quarterly's second decade, 2000–2009

In a reprise of Lowe and Gardner's (2000) review of The Leadership Quarterly's (LQ) first decade as a premier outlet for scholarly leadership research, we review 353 articles published in LQ during its second decade. Multiple methods were employed to prepare this review, including: interviews with the journal's current Senior Editor and Associate Editors; an assessment of LQ's impact, reputation, and most cited articles through citation analyses; a content analysis of article type (theory, empirical, and methods), contributors (e.g., discipline, nationality, and institutional affiliation), theoretical foundations, research strategies, sample location/type, data collection methods, and analytical procedures; survey and follow-up focus groups conducted with LQ Editorial Review Board members; and qualitative analyses to assess the prevalent themes, contributions, and trends reflected in LQ during its second decade. Drawing from these sources, we describe anticipated directions for future research.     

Romancing leadership: Past, present, and future

This paper presents a review of the romance of leadership and the social construction of leadership theory 25 years after it was originally introduced. We trace the development of this theoretical approach from the original formulation of the romance of leadership (RoL) theory as attributional bias through its emergence as a radical, unconventional approach that views leadership as a sensemaking activity that is primarily ‘in the eye of the beholder.’ We subsequently review research published in management and organizational psychology journals, book chapters and special issues of journals from 1985 to 2010. Three overall themes emerged from this review: 1) biases in (mis)attributions of leadership, including attributions for organizational success and failure; 2) follower-centered approaches, including the role of follower characteristics, perceptions, and motivations in interpreting leadership ratings; and 3) the social construction of leadership, including interfollower and social contagion processes, the role of crisis and uncertainty, and constructions and deconstructions of leadership and CEO celebrity in the media. Within each of these themes, we examine developments and summarize key findings. Our review concludes with recommendations for future theoretical and empirical work in this area.     

Embodying who we are: Leader group prototypicality and leadership effectiveness

Leadership is a process enacted in the context of a shared group membership, and leadership effectiveness is contingent on followers' perceptions of the leader as a group member. Addressing this role of group membership, the social identity theory of leadership puts leader group prototypicality, the extent to which the leader is perceived to embody group identity, center-stage in leadership effectiveness. I review empirical research in leader group prototypicality, concluding there is a robust empirical basis for the key propositions of the social identity theory of leadership. I also identify newer developments that extend and enrich the social identity analysis of leadership, including attention to the roles of uncertainty, leader fairness, leader–follower relationship, leader self-perceived prototypicality, and leadership of creativity and innovation.     

Sustainable supply chain network design: An optimization-oriented review

Supply chain network design (SCND) models and methods have been the subject of several recent literature review surveys, but none of them explicitly includes sustainable development as a main characteristic of the problem considered. The aim of this review is to bridge this gap. The paper analyzes 87 papers in the field of supply chain network design, covering mathematical models that include economic factors as well as environmental and/or social dimensions. The review is organized along four research questions asking (i) which environmental and social objectives are included, (ii) how are they integrated into the models, (iii) which methods and tool are used and finally (iv) which industrial applications and contexts are covered in these models. The review finds that there are a number of limitations to the current research in sustainable SCND. The narrow scope of environmental and social measures in current models should go beyond limited greenhouse gas indicators to broader life-cycle approaches including new social metrics. The more effective inclusion of uncertainty and risk in models with improved multi-objective approaches is also needed. There are also significant gaps in the sectors used to test models limiting more general applicability. The paper concludes with promising new avenues of research to more effectively include sustainability into SCND models.     

Leadership as social identity management: Introducing the Identity Leadership Inventory (ILI) to assess and validate a four-dimensional model

Although nearly two decades of research have provided support for the social identity approach to leadership, most previous work has focused on leaders' identity prototypicality while neglecting the assessment of other equally important dimensions of social identity management. However, recent theoretical developments have argued that in order to mobilize and direct followers' energies, leaders need not only to ‘be one of us’ (identity prototypicality), but also to ‘do it for us’ (identity advancement), to ‘craft a sense of us’ (identity entrepreneurship), and to ‘embed a sense of us’ (identity impresarioship). In the present research we develop and validate an Identity Leadership Inventory (ILI) that assesses these dimensions in different contexts and with diverse samples from the US, China, and Belgium. Study 1 demonstrates that the scale has content validity such that the items meaningfully differentiate between the four dimensions. Studies 2, 3, and 4 provide evidence for the scale's construct validity (distinguishing between dimensions), discriminant validity (distinguishing identity leadership from authentic leadership, leaders' charisma, and perceived leader quality), and criterion validity (relating the ILI to key leadership outcomes). We conclude that by assessing multiple facets of leaders' social identity management the ILI has significant utility for both theory and practice.     

Social capital and business and management: Setting a research agenda

This paper adopts the template of systematic reviewing and provides an up-to-date synthesis of the literature on social capital and business and management. The review demonstrates that social capital research is concentrated into three core dimensions: structural, relational and cognitive. First, structural social capital includes social interaction and the frequency of contact and connectivity levels among and between actors' network relations. Secondly, relational social capital refers to the underlying normative conditions of trust, obligation, expectation and identity that guide actors' network relations. Thirdly, cognitive social capital refers to the meaningful contexts of communication among and between actors, and includes the shared language, codes and narratives used to create understanding. However, the rich linkages between structural, relational and cognitive social capital across equivalent/hierarchical social space and geographical boundaries are neglected. A further research focus identified is that the role of face-to-face and the increasingly routine tool of electronic mediated communication may produce different characteristics and levels of social capital. The paper also discusses the ways in which critical realism and mixed methodology may enhance understanding of the process-based linkages between structural, relational and cognitive social capital.     

Authentic leadership: A review of the literature and research agenda

The past decade has seen a dramatic increase in scholarly interest in the topic of authentic leadership. We review this literature with the goal of clarifying the state of knowledge in the field. We begin with a historical overview of the construct's definition and evolution. Next, we present the results of a content analysis of 91 publications that focus on authentic leadership. Specifically, we examined the publication type (theoretical, empirical, and practitioner), contributors (e.g., discipline, nationality, and institutional affiliation), theoretical foundations, research strategies, sample location/type, data collection methods, analytical procedures, and nomological network of authentic leadership. We conclude by presenting an agenda for future research.     

What explains cultural differences in leadership styles? On the agricultural origins of participative and directive leadership

Why do we observe either participative or directive leadership in organizations? I test an evolutionary-informed theory suggesting that organizational leadership is currently less participative (i.e., close supervision, rare delegation) among societies that used intensive forms of agriculture in the past. Intensification caused increased social complexity and skewed power distribution, promoting the emergence of directive leaders and eventually shaping followers' preferences for and perceptions of leadership. Combining evidence, secondary data, and methods developed in economics, anthropology, and applied psychology, I document a negative relationship between traditional agricultural intensity and followers' participative leadership prototypes. I then study the link between traditional agriculture and reliance on delegation to subordinates across firms. I discuss competing hypotheses, explore the interplay between traditional agriculture and organizational-level factors, and show that traditional agricultural intensity does not predict most other leadership prototypes and management practices. Implications for leadership theory–with a focus on evolutionary approaches–are finally discussed.     

Leadership emergence in face-to-face and virtual teams: A multi-level model with agent-based simulations,quasi-experimental and experimental tests

With leadership as a major predictor of team performance in both face-to-face and virtual teams, research on differences in leadership emergence in these contexts seems warranted. We offer a multi-level model analyzing the roles of degree of team virtuality and density of social network ties as boundary conditions on leadership emergence, viewed as a fundamentally social–cognitive process. Using agent-based modeling and simulations, our results suggest that virtuality moderates the relationships between cognitive ability, extraversion, and self-efficacy (as independent variables) and leadership emergence (as dependent variable); and density of network ties serves as a moderator for the associations of cognitive ability and self-efficacy with leadership emergence. Subsequent quasi-experimental and experimental tests support the role of density of network ties as a moderator for the association of extraversion with leadership emergence. Implications of these findings and future paths for research bridging the fields of leadership, team virtuality and social networks are discussed.     

Journal of International Management: A 25-year review using bibliometric analysis

The Journal of International Management (JIM) is a leading international academic journal in the field of international business. This study presents a retrospect of the publications in JIM for the last 25 years (as JIM was founded in 1995) through a bibliometric methodology using the Scopus database and Web of Science. The study graphically maps the bibliographic material using VOS viewer software and applies co-citation analysis, bibliographic coupling, and co-occurrence of author keywords. We identify that the journal has expanded consistently and steadily in terms of both number of publications and citations. The collaboration network has expanded over the years, and the geographical focus is more global, encompassing Asia and Oceania. Bibliographic coupling of JIM publications reveals several distinct, major themes in the international management/business domain. Conventional international management themes that have emerged include market entry modes, globalization, international human resource management, cross-cultural management/leadership, and expatriate management. New emerging themes include emerging markets, global sourcing, innovation performance, digital firms, diversity of global teams, internationalization in uncertain environments, and virtual teams. A summary of the shifting research trends and themes in the discipline and their development is presented in this review, culminating in future directions for prospective publishers of JIM.     

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.     

A critical review of race and ethnicity in the leadership literature: Surfacing context,power and the collective dimensions of leadership

Leadership studies focusing on race–ethnicity provide particularly rich contexts to illuminate the human condition as it pertains to leadership. Yet insights about the leadership experience of people of color from context-rich research within education, communications and black studies remain marginal in the field. Our framework integrates these, categorizing reviewed studies according to the effects of race–ethnicity on perceptions of leadership, the effects of race–ethnicity on leadership enactments, and actors' approach to the social reality of race–ethnicity. The review reveals a gradual convergence of theories of leadership and theories of race–ethnicity as their relational dimensions are increasingly emphasized. A shift in the conceptualization of race–ethnicity in relation to leadership is reported, from a constraint to a personal resource to a simultaneous consideration of its constraining and liberating capacity. Concurrent shifts in the treatment of context, power, agency versus structure and causality are also explored, as are fertile areas for future research.     

Leadership in the Plural

This paper reviews the literature on forms of leadership that in one way or other imply plurality: that is, the combined influence of multiple leaders in specific organizational situations. We identify four streams of scholarship on plural leadership, each focusing on somewhat different phenomena and adopting different epistemological and methodological assumptions. Specifically, these streams focus on sharing leadership in teams, on pooling leadership at the top of organizations, on spreading leadership across boundaries over time, and on producing leadership through interaction. The streams of research vary according to their representations of plural leadership as structured or emergent and as mutual or coalitional. We note tensions between perspectives that advocate pluralizing leadership in settings of concentrated authority and those concerned with channeling the forms of plurality naturally found in diffuse power settings such as professional organizations or inter-organizational partnerships. It is suggested that future research might pay more attention to social network perspectives, to the dynamics of plural leadership, to the role of power, and to critical perspectives on leadership discourse.     

Let’s agree about nice leaders: A literature review and meta-analysis of agreeableness and its relationship with leadership outcomes

In this study, we draw from 22 years of research in leadership to investigate the ambiguous relationship between the personality trait agreeableness and leadership. First, we conduct a comprehensive review of the leadership literature to build a foundational understanding of leader agreeableness that includes providing a broad definition for agreeableness, identifying emerging trends, and proposing an agenda for future research. Second, using the literature review as our theoretical foundation, we conduct a meta-analysis from the same body of literature to quantitatively decompose the relationship between leader agreeableness and leadership emergence and effectiveness. We also hypothesize and test the contextual moderating effects for gender, leadership level, and cultural context (as reflected by individualism-collectivism). Collectively, our findings provide a framework for future research on leadership agreeableness and support the notion that nice (highly agreeable) leaders can emerge as effective leaders.     

Visualizing the landscape and evolution of leadership research

Complementing prior quantitative and qualitative reviews of the leadership literature, we conduct a bibliometric analysis of leadership articles. Our bibliometric review provides a different perspective by portraying the landscape and developmental trajectory of leadership research over time via co-citation and co-occurrence analyses. Using a scientific visualization tool CiteSpace and 6528 leadership works collected from the Web of Science database from 1990 to 2017, we detect and visualize the landscape of leadership research and track how this landscape has evolved. After mapping the landscape, we discuss the insights gleaned from our bibliometric review, with a focus on open questions, future research directions, and implications. In doing so, our review provides readers with a systematic understanding of the development of the leadership field and a roadmap to spark leadership research and move this literature forward.
