Purpose – The purpose of this paper is to investigate whether a sparse and relatively small giant component (GC) will capture highly productive authors. Design/methodology/approach – The author used a geographically dispersed data set involving authors in the field of economics in ten countries in Southeast Asia and applied social network analysis methods to investigate the structure and dynamics of GCs. Findings – Results reveal that a GC, characterized by both low density and small size, can still capture a significant percentage (68 per cent of the top 25) of the most productive authors. There seems to be a topological backing for this occurrence. The number of direct connections (or “degree”) in the GC was correlated with research productivity, such that high-degree authors were almost twice as productive as low-degree authors. It is probable that productive authors having higher than average degrees may be the cause of the formation of the GC. The author hypothesize that irrespective of its size or sparseness, GCs in co-authorship networks may still represent the seat of main intellectual activity in the network. Originality/value – This is one of the first studies to quantitatively analyse the ability of a co-authorship-based less-prominent GC to capture prominent authors.

Purpose The dynamic career scenario and the significant change from traditionally placing careers in employers’ hands to self-managing one’s careers have sparked profound scholarly interest in career growth. This paper aims to analyze quadricentennial literature on career growth published during the years 1995 through 2020. In this paper, through bibliometric and integrative reviews, the authors address the two critical questions, “what do we know?” and “where should we go?” While the bibliometric review examines the evolution and trends, the integrative review examines the dynamics of conceptual frameworks, primary research foci, research context and quality in research designs and methods. Design/methodology/approach The study adopted preferred reporting items for systematic reviews and meta-analyses guidelines to identify the papers for this review. The data set comprised 102 papers and 60 papers for bibliometric and integrative review, respectively. “CiteSpace” is used for the bibliometric analysis and the template designed by the authors is used for the integrative review. Findings The results present conceptual clarification for career growth and its related constructs. The bibliometric analysis findings highlight the extensive research on career growth followed by organizational career growth and career growth opportunities. The findings also show that seven of the top 10 productive authors are from China. This study also identifies theoretical, conceptual and methodological opportunities and provides recommendations intended to further research engagements across the different aspects of career growth. Originality/value To the best of the authors’ knowledge, this is the first study to introduce bibliometric analysis into career growth literature. This research adopts an integrative review approach and offers insights into career growth literature.

Purpose The purpose of this paper is automatic classification of TV series reviews based on generic categories. Design/methodology/approach What the authors mainly applied is using surrogate instead of specific roles or actors’ name in reviews to make reviews more generic. Besides, feature selection techniques and different kinds of classifiers are incorporated. Findings With roles’ and actors’ names replaced by generic tags, the experimental result showed that it can generalize well to agnostic TV series as compared with reviews keeping the original names. Research limitations/implications The model presented in this paper must be built on top of an already existed knowledge base like Baidu Encyclopedia. Such database takes lots of work. Practical implications Like in digital information supply chain, if reviews are part of the information to be transported or exchanged, then the model presented in this paper can help automatically identify individual review according to different requirements and help the information sharing. Originality/value One originality is that the authors proposed the surrogate-based approach to make reviews more generic. Besides, they also built a review data set of hot Chinese TV series, which includes eight generic category labels for each review.

Capital Regulations

Purpose – The purpose of this study is to replicate Avery and Berger’s (1991) analysis using data from 2001 through 2011. Although risk-based capital (RBC) regulation is a key component of US banking regulation, empirical evidence of the effectiveness of these regulations has been mixed. Among the first studies of RBC regulation, Avery and Berger (1991) provide evidence from data on US banks that new RBC regulations outperformed old capital regulations from 1982 through 1989. Design/methodology/approach – Using data from the Federal Reserve’s Call Reports, the authors compare banks’ capital ratios and RBC ratios to five measures of bank performance: income, standard deviation of income, non-performing loans, loan charge-offs and probability of failure. Findings – Consistent with Avery and Berger (1991), the authors find banks’ risk-weighted assets to be significant predictors of their future performance and that RBC ratios outperform regular capital ratios as predictors of risk. Originality/value – The study improves on Avery and Berger (1991) by using an updated data set from 2001 through 2011. The authors also discuss some potential limitations of this method of analysis.

Purpose This paper aims to examine the structure and dynamics of scholarly publications dealing with Wikipedia. The research also aims to investigate how such research evolved since its launch in 2001. Design/methodology/approach Wikipedia has grown to be the biggest online encyclopedia in terms of comprehensiveness, reach and coverage. Based on 1,040 PubMed Wikipedia documents written by 5,280 authors over two decades (2001–2021), this paper conducts a bibliometric review of the intellectual structure of scholarly publications dealing with Wikipedia. Findings Results show that annual scholarly publications on Wikipedia growth rate is 13.26. Major outlets publishing Wikipedia’s research are PloS One, the Journal of Medical Internet Research, Nucleic Acids Research, Studies in Health Technology and Informatics, Bioinformatics and the International Journal of Medical Informatics. Results also show that the author collaboration network is very sparse, signifying rather negligible collaboration among the authors. Furthermore, results reveal that the Wikipedia research institutions’ collaboration network reflects what is sometimes termed Wikipedia’s “North-South divide,” indicating limited collaboration between rich and poor nations’ institutions. Finally, the multiple correspondence analysis applied to obtain the Wikipedia research conceptual map and its intellectual structure reveals the intellectual thrust and the diversity of the scholarly publications dealing with Wikipedia. Originality/value To the best of the author’s knowledge, this research represents the first application of bibliometric methods to investigate two decades of scholarly publications dealing with Wikipedia based on the PubMed database.

Design/methodology/approach This paper adopts a qualitative methodology and presents interview data from key actors involved in minority equity sponsorship agreements. Findings The findings of the paper include major characteristics of minority equity sponsorship agreements including the motivations, dynamics and resources exchanged by sponsoring firms and clubs in these relationships, based on the experiences of key actors from firms, clubs and other key stakeholders, and a conceptual model for forming and maintaining these relationships. Practical implications Sponsorships are increasingly evolving into minority equity sponsorship agreements, particularly in the European market. The findings of this study assist sponsoring firms and the executives of clubs in better understanding the dynamics and stakeholder-related consequences of these relations. Originality/value The findings of this paper illustrate the differences between minority equity sponsorship agreements and both traditional sponsorships and minority equity alliances. The findings also identify major characteristics of these relationships and the interdependencies among these characteristics.

Purpose The purpose of this paper is to examine how subnational institutions within a country explain the performance consequences of open innovation (OI) in emerging market enterprises (EMEs). Design/methodology/approach The paper conducts a regression analysis by using a novel panel data set comprising of 438 innovative Chinese firms over the period of 2008-2011. Findings The authors show that although on average openness to external actors improves innovation performance this effect is pronounced for EMEs that operate in subnational regions with a higher level of intellectual property rights (IPR) enforcement and of factor market development. The findings point to the context-dependent nature of OI strategy and the complementary effect of institutional parameters in emerging markets and help to reconcile the contrasting findings regarding the effect of OI in the prior literature. Originality/value This paper extends the literature on OI by suggesting that the analysis of the performance consequences of OI strategy should go beyond the nexus between OI and firm performance, and instead, focus on subnational-specific institutions, such as region-specific IPR enforcement, factor market development and intermediation market development, that may facilitate or constrain the effect of OI model.

The Global Financial Crisis

Purpose This paper aims to investigate how firms from emerging economies choose among different international bond markets: global, US144A and Eurobond markets. The authors explore if the ranking in regulatory stringency –global bonds have the most stringent regulations and Eurobonds have the most lenient regulations – leads to a segmentation of borrowers. Design/methodology/approach The authors use a novel data set from emerging economy firms, treating them as consolidated entities. The authors also obtain descriptive evidence and perform univariate non-parametric analyses, conditional and multinomial logit analyses to study firms’ marginal debt choice decisions. Findings The authors show that firms with poorer credit quality, less ability to absorb flotation costs and more informational asymmetries issue debt in US144A and Eurobond markets. On the contrary, firms issuing global bonds – subject to full Securities and Exchange Commission requirements – are financially sounder and larger. This exercise also shows that following the global crisis, firms from emerging economies are more likely to tap less regulated debt markets. Originality/value This is, to the authors’ knowledge, the first study that examines if the ranking in stringency of regulation – global bonds have the most stringent regulations and Eurobonds have the most lenient regulations – is consistent with an ordinal choice by firms. The authors also explore if this ranking is monotonic in all determinants or there are firm-specific features which make firms unlikely to borrow in a given market. Finally, the authors analyze if there are any changes in the debt-choice behavior of firms after the global financial crisis.

Purpose – This study investigated whether a course which focused on raising students' awareness of sustainability, from a balanced perspective, that is, one which gives equal consideration to the social and economic aspects as well as the environmental would produce graduates with the knowledge and commitment required to drive the sustainability agenda forward. The paper aims to discuss these issues. Design/methodology/approach – An analysis of students' final entries in their reflective journal was used to explore whether their views on sustainability reflected a balanced view. Findings – The findings of this research confirmed previous studies showed that initially students do have an enviro-centric bias. It also showed that despite experiencing a pedagogical approach which challenged views by encouraging discussion, debate, and reflection and which provided what was considered to be a balanced view of sustainability, many of the students still leaned towards an environmentally focused perspective of sustainability. Research limitations/implications – The conclusions are based on one data set but are supported by other data described in the paper. Practical implications – The finding led the authors to conclude that a concerted holistic effort within and across courses is needed within tertiary institutions if students' views about sustainability are to be challenged. Originality/value – The outcomes demonstrate that students' reflective journals can be used to gather information about the change in students' perceptions about sustainability.

PurposeThe authors investigate the contributions of social capital (SC) dimensions (bridging, bonding and linking) in crowdfunding campaigns by comparing the dynamics of agri-food businesses with those of two other sectors – cultural and technological.Design/methodology/approachThe authors develop linear regressions on a proprietary data set of 5,290 projects launched on the Italian platform “Produzionidalbasso.com”, from 2014 to 2020.FindingsThe authors’ findings suggest that combining the three social capital dimensions (bridging, bonding and linking) has a more substantial overall effect on the number of backers involved in agri-food projects than in cultural and technological projects. Agri-food entrepreneurs effectively mobilize all resources embedded in the SC dimensions and therefore create the conditions to develop new ties that financially support the project.Practical implicationsAgri-food entrepreneurs may benefit from those results improving their funding strategies. Therefore, agri-food entrepreneurs can explore and exploit the instruments available on the CFD platform – video and rewards associated with the campaign – gaining more benefit from the backers involved compared with other project categories.Originality/valueThe study proposes a broader perspective regarding SC that encompasses the proponent, the company and the campaign with three different types of ties: bonding, bridging and linking. These SC dimensions can differently shape diverse sectors and this eclectic configuration can differentiate the effects of SC in crowdfunding campaigns. This study pinpoints how crowdfunding determinants change, based on project categories.

Credit Association

Purpose The emerging markets have been witnessing a remarkable revival of rotating savings and credit associations (ROSCAs) serving as alternative informal financing and investment platforms, also known as savings-based finance (SBF) in Turkey. The purpose of this study is to present the SBF model mathematically, analyse the performance of the SBF sector and propose a new Sharīʿah-compliant SBF model for the acquisition of durables. Design/methodology/approach The paper thoroughly reviews the concept and practice of ROSCA across the globe, mathematically models and empirically analyses the performance of Turkish SBF companies using a unique data set. Findings The study formulates a two-person SBF model and proposes a Mudarabah-Wakalah hybrid model with a new investment feature. It is found that the concept of ROSCA is being operationalized in 105 countries across the globe under different names with slight business model modifications. The research also reveals that the demand for financing of durables in Turkey significantly increased in recent years with the demand for housing is twice greater compared to vehicles. Most importantly, a strong significant inter- and intra-comovement is observed between these durables implying that the success of the sector in one segment has attracted the customers to other SBF products. It shows that the SBF institutions can effectively serve as the alternative financing houses for pooling savings and financing the durables, and they have strong potential to capture a larger financial market share in Turkey and even globally. Originality/value The study constructs mathematical models and proposes a new investment wing to an existing SBF wealth fund.
