This paper seeks to explore vertical and horizontal leadership and the relationship of the form of leadership to effectiveness in Swedish cross-professional health care teams.

Questionnaire data were collected from a sample of 47 teams and observation data from a sub-sample of 38 teams. Data on leadership were condensed to indices: directive and participative leadership (vertical leadership) and functional influence and self-regulation (horizontal leadership). Effectiveness was estimated using five measures: team climate, self-assessed effectiveness, teamwork organisation, assessments of results from a simulated case conference (case quality) and manager-rated effectiveness.

Positive relationships were found between leadership and effectiveness with one exception: case quality was negatively associated with vertical leadership though positively to functional influence. When controlled for team climate the correlations between self-assessed effectiveness and leadership disappeared. However, it remained between vertical leadership and the assessment of teamwork organisation. The results suggest that hierarchical and horizontal/shared leadership are complementary forms.

The small number of teams together with the problem of causality in this cross-sectional study are the main limitations.

One implication for practice is the need for clarification of how leadership and influence should be distributed from a contingency perspective.

This study takes both horizontal and vertical leadership into account compared with previous studies often focusing on one facet. In addition, cross-professional health care teams with their special characteristics are underrepresented within research on team leadership.

This research aims to examine the intellectual structure of iMetrics through author co-citation analysis.

This research uses common techniques in bibliometrics and social network analysis. It analyses 5,944 records from the Web of Science in the field of iMetrics that are published between 1978 and 2014.

Findings indicated that researchers including “Garfield”, “Egghe”, “Glanzel”, “Leydesdorff” and “Price” have received many co-citations. The author co-citation analysis in iMetrics resulted in eight thematic clusters, including “theoretical foundations and citation analysis”, “sociology of science”, “science mapping and visualization”, “network analysis”, “classic laws of bibliometrics”, “webometrics”, “technometrics” and “miscellaneous”. “Theoretical foundations and citation analysis” is the biggest cluster which comprises 59 authors. The results suggest the crucial role of price medallists in shaping the intellectual structure of knowledge in iMetrics.

Extracting the patterns embedded in the knowledge structure of iMetrics studies provides beneficial information for both researchers and policymakers. This research study is valuable that used an appropriate set of records regarding both recall and precision. Furthermore, this study helps us better understand the characteristics of iMetrics, its subject areas, and the prominent authors in those areas.

The purpose of this paper is to characterize library and information science (LIS) as fragmenting discipline both historically and by applying Whitley’s (1984) theory about the organization of sciences and Fuchs’ (1993) theory about scientific change.

The study combines historical source analysis with conceptual and theoretical analysis for characterizing LIS. An attempt is made to empirically validate the distinction between LIS context, L&I services and information seeking as fragmented adhocracies and information retrieval and scientific communication (scientometrics) as technologically integrated bureaucracies.

The origin of fragmentation in LIS due the contributions of other disciplines can be traced in the 1960s and 1970s for solving the problems produced by the growth of scientific literature. Computer science and business established academic programs and started research relevant to LIS community focusing on information retrieval and bibliometrics. This has led to differing research interests between LIS and other disciplines concerning research topics and methods. LIS has been characterized as fragmented adhocracy as a whole, but we make a distinction between research topics LIS context, L&I services and information seeking as fragmented adhocracies and information retrieval and scientific communication (scientometrics) as technologically integrated bureaucracies.

The paper provides an elaborated historical perspective on the fragmentation of LIS in the pressure of other disciplines. It also characterizes LIS as discipline in a fresh way by applying Whitley’s (1984) theory.

The purpose of paper is twofold. First, it provides a consolidated overview of the existing literature on “big data” and second, it presents the current trends and opens up various future directions for researchers who wish to explore and contribute in this rapidly evolving field.

To achieve the objective of this study, the bibliographic and network techniques of citation and co-citation analysis was adopted. This analysis involved an assessment of 57 articles published over a period of five years (2011-2015) in ten selected journals.

The findings reveal that the number of articles devoted to the study of “big data” has increased rapidly in recent years. Moreover, the study identifies some of the most influential articles of this area. Finally, the paper highlights the new trends and discusses the challenges associated with big data.

This study focusses only on big data concepts, trends, and challenges and excludes research on its analytics. Thus, researchers may explore and extend this area of research.

To the knowledge of the authors, this is the first study to review the literature on big data by using citation and co-citation analysis.

The growing demands of work and life have shifted the concept of work-life balance to work-life integration (WLI). The success of integration depends upon the flexibility to perform the duties. This paper aims to explore the factors that affect WLI and the role of flexible work arrangements (FWAs) in the process of WLI.

Systematic literature review was used to explore the concept of WLI and FWAs. A bibliometric analysis was carried out with Bibexcel and VoSviewer.

This paper explained the organizational and personal factors that create the demand for WLI. The FWAs, perceived flexibility, technology and self-efficacy have important roles in WLI. The result of WLI can be enrichment or strain, depends upon how effectively the work-life domains are integrated.

This paper explores the work-life from both personal and organizational views. The findings of this paper will be useful to design the organizational policies and work arrangements that match the requirements of employees and organizations. This paper helps to develop the future research agenda of investigating the relations of WLI to performance, organizational policies and personal factors.

The purpose of this paper is to review the existing literature on supply chain performance measures and metrics (PMMs). It provides a critical evaluation of 234 articles published in past 24 years.

The paper examines the studies published from 1991 to 2014 by adopting the bibliometric technique of citation and co-citation analysis.

The analysis of the results indicate that the number of articles on supply chain PMMs is increasing at its fastest pace in the past few years. Furthermore, the study identifies some of the most influential articles on performance measurement and metrics. Finally, it concludes that there has been a transition from traditional to more sophisticated performance measurement system.

This study focuses only on supply chain performance measurement and metrics and excludes research on performance management and control. Thus, researchers may explore and extend this area of research.

To the knowledge of the authors, this is the first study to review the literature on supply chain PMMs by using citation and co-citation analysis. The study includes 234 articles over the time of 24 years (1991-2014).

In recent years, author and document citation and co-citation analyses have often been applied to map the “intellectual structure” of different scientific fields, including management and international business. However, the technique of bibliographic coupling between scientific documents, which seeks to identify active research fronts in a scientific field or discipline, has been less commonly used. This study utilized this technique to identify and visualize the research fronts in the context of papers on emerging markets multinational enterprises (EM-MNEs) recently published in a wide variety of journals. The aim is not only to complement and expand the results obtained in prior studies that have used other types of systematization, such as qualitative content analysis methodology but also to propose avenues for future research.

The primary databases utilized to carry out the present research work – both comprised in the Web of Science™ (WoS) Core Collection – were: the Social Sciences Citation Index® (SCI) developed by the Institute for Scientific Information (ISI) and the Emerging Sources Citation Index. A total of 496 “peer-reviewed journal articles” published between 2014 and December 30, 2019 were retrieved. With regards to the methodology, bibliometric methods were utilized, as well as social network analysis (SNA).

Particularly, the analytical techniques employed – adopting a “quantitative” method of a deductive character – allowed the identification of the most active research “fronts” in international research related to the topic under analysis: the phenomenon of EM-MNEs.

The present study has several limitations resulting from the utilization of bibliometric methods applied in the analyses performed.

The authors believe that this research is of value for future researchers since it allows the identification of research “fronts,” which shape the vanguard of knowledge and reveal current trends and future directions in the area under examination.

The purpose of this paper is to investigate the core themes of service research by analysing citations in the International Journal of Service Industry Management (IJSIM). It also aims to discuss changes in the discipline's sub‐fields and identifies emerging topics.

The paper is an empirical analysis of citations and co‐citations from the IJSIM. Network and factor analysis are used to analyse and group the data. The study is unique in performing the analysis at the individual publication level, rather than following the normal aggregated author co‐citation analysis method.

The study examines only IJISM. Future study on other top journal such as Journal of Service Research would provide a more complete picture on service research.

The study identifies that the core ideas of service research centred on service quality and customer satisfaction. Also identified are periphery areas which may become more significant.

The main contribution of this article is the use of the novel network analysis technique to analyze the 15,003 citations in the 435 articles published in IJSIM between 1990‐2005. This is a quantitative analysis unlike previous review articles which rely largely on the observations and reflections of pioneering researchers.

The evidence on the causality of energy consumption and economic growth nexus is plentiful in energy economics studies. The empirical research results documented are dissimilar because different methodologies, variables, time or data sources have been used. This study aims to examine and evaluate the existing literature to reveal the research inclinations, including future research directions. Therefore, from an application perspective, this study performed a bibliometric analysis that can serve as a basis for understanding research trend in relation to nexus of energy consumption and economic growth, its comprehensive research outcomes and the growing research inclination.

Using keyword search and delimiting criteria, 969 articles are selected for bibliometric analysis. Citation analysis, author keyword co-occurrence analysis, co-authorship and co-citation analysis are performed to assess the productive countries, authors, journals, articles, energy research trends, collaborating scholars and more frequently cited together articles.

Research results of the paper present a comprehensive research understanding of energy consumption and economic growth nexus studies. In terms of trending research topics, sustainable development, population density, urbanization, energy efficiency, energy intensity and carbon emission constitute a distinguished association that indicates the growth of these diverse fields’ study about energy.

As a policy implication and direction, the trade openness, natural gas/ resources, environmental kuznets curve, fossil-fuel consumption, agricultural land, financial development and foreign investments can be studied along with energy usage and economic growth nexus studies.

The results provide valuable insight for the researchers selecting their potential disciplines for study, combining various techniques to deal with complex problems, identifying prospective co-authors and identifying the appropriate institutes for accompanying academic studies or collaborative research.

To the best of the author’s knowledge, this study is one of its kind regarding investigating the trend of energy consumption and economic growth relationship-related research published from 2001 to 2020 on the Scopus database.

The purpose of this paper to investigate the major themes of operations management by analysing citations in IJOPM. It aims to discuss changes in the discipline's sub‐fields and identifies emerging topics.

The paper is an empirical analysis of citations and co‐citations from IJOPM. Network and factor analysis are used to analyse and group the data.

The study demonstrates that the persistent central ideas of operations management concern manufacturing strategy, with specific interests in strategy typologies, best practices, and the resource‐based view. Other central themes are performance measurement, the case study method, and process management. The plotting of subfield trajectories shows that recent studies are seeking a more subtle understanding of operations management by considering its practice in relation to strategy, context and resources. Emerging subjects within the field include supply chain management, lean management systems, theory building from quantitative data and sustainable resource limits to capability.

The study is unique in performing the analysis at the individual publication level rather than following the normal aggregated author co‐citation analysis (ACA) method. The potential problems with citation/co‐citation studies are discussed.
