Since March (1991) presented his ideas on organizational learning, hundreds of empirical tests have been conducted on relationships among the activities of exploration, exploitation, ambidexterity, and firm performance. Despite continued interest in his ideas, there has not been a systematic assessment of extant research to reveal whether, and to what extent, these activities relate to firm performance. This study uses meta-analysis to take a next step by aggregating results of 117 studies from more than 21,000 firms. I find strong performance effects for exploration and exploitation, but contrary to received theory, I discover ambidexterity yields weaker effects than a focus on either exploration or exploitation. Thus, I leverage these findings to offer future research opportunities.

This paper aims to explore the relationships among perceived organizational support, positive relationships at work and intent to turnover through a social exchange theory lens. The main contribution of this paper is the investigation of different types of positive workplace relationships on employee withdrawal behaviors.

A 49-item survey was developed through a review of literature related to positive workplace relationships and intent to turnover. Surveys were made available to 200 healthcare employees; 73 surveys were accurately completed and used to test a mediated model of positive relationships at work.

Positive relationships at work were found to have a mediating effect between perceived organizational support and intent to turnover. Additionally, perceived organizational support was found to have direct and indirect effects on intent to turnover.

Managers can affect employees’ intentions to turnover by improving practices that provide support to employees and encouraging positive relationships with coworkers. Additional literature related to our variables of interest suggests that employees perceive more support when their organizations offer commensurate rewards, opportunities for growth and participation in decision making.

This study speaks to those researchers and managers interested in employees’ motivations for staying in or leaving from their organizations. Turnover and related withdrawal behaviors are expensive for organizations, so discovering the factors that members value offers organizations the ability to affect their members’ intentions to turnover. Additionally, the exploration of relationships between perceived organizational support and positive relationships at work suggests that different support mechanisms play different roles in affecting organizational and individual outcomes.

Despite a growing body of research on exploration and exploitation, scholars have tended to study the phenomena from a narrow perspective mostly within larger, well-established organizations. However, it is still far from obvious how top management within small-to-medium sized enterprises (SMEs) are to address the liability of newness and seek access to resources and capabilities relevant for the pursuit of exploration and exploitation. Resource sourcing and allocation decisions are particularly critical in SMEs and must be aligned with the firm’s fundamental strategic intent and growth model. For example, organizations following a stage model by first developing a domestic market and then expanding globally will require different bundles of resources and capabilities than organizations that are designed to conquer the global arena. Indeed, management systems will likely need to adapt across the firm life cycle such that it can fulfill an explorative function in the earlier stages and an exploitative function in later ones. Hence, early-stage ventures have to master the resource reallocation process which is contingent on their access to capital. Across the firm life cycle, venture capitalists can tap into the growth potential of early-stage ventures is a key factor behind their successful short-term innovative performance as well as long-term survival.

This study aims to investigate an intersecting single-walled structure fabricated using wire-arc directed energy deposition (waDED). Because of the highly complex geometrical features of this structure, characterisation is used to identify potential weak points and provide a benchmark for future complex components.

A structural component with a process-specific design is built using additive manufacturing of an Al-Mg alloy and analysed using micro-computed tomography. Scans are carried out at different resolutions and subsequently compared to microsections. The chemical composition and hardness are also examined. These investigations provide an enhanced understanding of defects and overall quality of the manufactured parts.

The results show that very high-quality parts can be achieved using ER5183 alloy, even in intersecting areas. Defects in these regions are primarily caused by converging and diverging waDED paths and discontinuous waDED operations.

In addition to demonstrating the feasibility of complex structures using waDED, this study provides an overview of problem areas and potential improvements in waDED manufacturing.

The strategic entrepreneurship (SE) literature exists at the intersection of the strategy and entrepreneurship literatures and has grown rapidly over the past two decades. This study aims to document the proliferation of research papers and identifies the major thematic clusters of topics and other summary information for the SE research domain.

This is a systematic bibliometric review of 586 articles published over the period 2009–2019 in 143 journals. The inductive quantitative assessment of these articles uses meta-data driven techniques that prioritize reproducibility and rigor in the process of literature analysis.

This study identifies six main themes in the strategic literature, namely, Sustainable Competitive Advantage; Knowledge Management; Ecosystems; Strategy; Entrepreneurialism; and Organization and Management. It also reports data on a variety of issues including research techniques, country of data, co-author count and trends and differences between journals based on their journal impact factors and calls for more research in key areas.

An innovative original analytical tool was developed to facilitate the analysis of research papers in this growing field. This online tool allows multiple tags to be attached to each paper by multiple authors working simultaneously to identify keywords and other aspects that were subsequently used to identify six main thematic areas within the SE literature. This paper highlights emerging research trends and identifies gaps in the literature that provide opportunities for further research in this field.

In this second and concluding part of an extensive review of the management development literature, attention is directed to studies which have sought to describe and explain how managers are in fact made and to studies which have emphasised the contextual aspects of the process. The review is concluded with an overall assessment of the management development literature – its strengths and weaknesses – and with an analysis of the implications which this assessment carries for the conduct of future research. Crucial gaps are identified, not least of which is a general failure to locate descriptions of particular management development initiatives within the context of other ways in which the management stock is enhanced, replenished and managed. Another major shortcoming which is singled out as requiring urgent attention is the failure to place management development accounts and prescriptions within the wider context of organisational characteristics.

The purpose of this paper is to provide a comprehensive examination of different leadership constructs investigated extensively, namely transformational and transactional leadership, laissez-faire, consideration, and initiating structure, as well as leader-member-exchange. The theoretical overlap as well as the empirical correlations between these constructs is explored.

Overall, 735 correlations were analyzed to generate a meta-analytical correlation matrix.

The meta-analyses revealed highly interrelated leadership constructs (0.26<∣ρ∣<0.74). Results of confirmatory factor analyses suggest a one factor solution of leadership.

The uniqueness and construct validity of leadership constructs is challenged, calling for a revision of the respective leadership theories. Ultimately, an integrative theory of leadership should be developed which accounts for similarities as well as differences between leadership constructs. An integrated theory of leadership would help: researchers to combine their forces and, consequently, organizations across the globe to better select and develop leaders for the future.

By taking a critical, cross-theoretical compare and contrast approach, the present study yielded a comprehensive picture of the interrelationship and partial redundancy of several of the currently researched leadership constructs.

New insights into the overlap between leadership constructs were generated and confirmed by meta-analyses.

WE do not need to be reminded of the increasing importance of the electrical system in the modern aeroplane, either from the point of view of efficient operation of the aircraft or from the point of view of reliability and safety.
