Exploring COBRAs, its antecedents and consequences in the context of banking brands
Authors: Mishra Aditya Shankar 
Published: May 2021

PurposeBrands have started investing heavily in their social media pages. Especially for banks having credence nature, the importance of engaging customers with the brand-related content on their social media pages has become a challenge. The present study explores the role of various characteristics of a brand's social media marketing efforts (SMME) and individual customer's general online social interaction propensity (GOSIP) on the customers' engagement/online brand-related activities (COBRAs). The subsequent effect of COBRAs on key banking outcomes such as satisfaction, trust and loyalty has also been evaluated. The moderating role of the customer–brand relationship length has also been evaluated.Design/methodology/approachA two-stage mixed-method approach was used for the data collection. Two focus group discussions were conducted for the preliminary stage, which resulted in identifying five Indian banking brands as stimuli for further study. For the main study, an online survey link was shared with the members of the stimuli banking brands' social media pages. A total of 552 useable responses were collected. After performing the exploratory factor analysis and common method bias tests, the collected data were analyzed using structural equation modeling and multi-group analysis.FindingsThe results of the present study have added all five characteristics (namely, entertainment, interaction, trendiness, customization and electronic word of mouth) of SMME and GOSIP as the key antecedents of the customers' engagement with brand content on social media pages or COBRAs. COBRAs have been found influencing the customers' satisfaction, but evidence of influence on the trust and loyalty has not been found. The length of the relationship between customers and the banking brand has been observed as an important moderator for the satisfaction–trust–loyalty relationship.Originality/valueThe present study has three unique contributions to the literature. Firstly, the study evaluates the role of customer-brand engagement on the banking brand's favorable outcomes such as satisfaction, trust and loyalty. Secondly, the exploration of the role of various social media marketing activities that can enhance customer–brand engagement. And finally, the study tests the moderating role of the customer–brand length of the relationship on the complete set of marketing activities–engagement–loyalty relationships.
Developing marketing curriculum to make students workforce ready
Authors: Edmondson Diane , Matthews Lucy 
Published: May 2021

PurposeThe purpose of this paper is to investigate how to overcome the dilemma of the lack of student workforce readiness upon graduation. Based on experiential learning theory, the authors propose an innovative three-step approach to marketing curriculum to help address this dilemma.Design/methodology/approachThis study examines both quantitative and qualitative data. First, quantitative results were obtained from 5,222 end-of-course surveys of students taking an experiential learning course at a southeastern United States public university. Results were also obtained from 111 end-of-course surveys of students taking experiential learning courses in marketing. Second, qualitative results were obtained through a critical review of self-reflection assignments from over 1,000 students taking a variety of experiential learning marketing courses.FindingsThe authors identify a three-step process that can be used to develop curriculum that will better prepare students for entering the workforce. The advantages and disadvantages associated with this type of curriculum are also discussed. The outcomes indicate that an entire curriculum focused on experiential learning, self-reflection and ePortfolios will allow students to not only be better prepared for the workforce but also will help them be better communicators on what they have learned.Originality/valueIn this paper, the authors contribute to the literature by providing a curriculum-based approach to learning in order to minimize the gap between academic knowledge and workforce preparedness. Sample course projects, reflective prompts and grading rubrics are provided to aid others in the implementation of this type of curriculum.
Demographic dividend and economic growth in emerging economies: fresh evidence from the SAARC countries
Authors: Jafrin Nusrat , Mahi Masnun , Masud Muhammad Mehedi , Ghosh Deboshree 
Published: May 2021

PurposeThe study attempts to establish the relationship between demographic dividend and GDP growth rate by utilising panel data from 1990 to 2017 in Bangladesh, India, Pakistan, Nepal and Sri Lanka.Design/methodology/approachThis study employs the pooled OLS model, using data from the World Bank's database for the period 1990–2017 for five selected South Asia Association for Regional Cooperation (SAARC) countries.FindingsThe results reveal that demographic dividend affects economic growth in Bangladesh, India, Nepal, Sri Lanka and Pakistan, thereby supporting the demographic dividend hypothesis. For the country-specific analysis, it was also observed that demographic dividend impacts the economic growth of the five SAARC countries. In addition, growth of gross capital formation is highly significant for both aggregated and country-specific analyses. However, economic growth is unaffected by trade openness and unemployment rates. Moreover, the rate of labour force participation is negatively related to the GDP growth rate in the aggregated model.Originality/valueThis paper bestows insight into the fact that the impact of demographic dividend on the economic growth of the SAARC regions cannot be fully actualised if the workforce are underutilised. This region needs to adopt appropriate policies to strengthen the considerable benefits of demographic dividend on the economic growth.
Money creation process, banking performance and economic policy uncertainty: evidence from Tunisian listed banks
Authors: Khalfaoui Hamdi , Derbali Abdelkader 
Published: May 2021

PurposeThis paper aims to investigate the relationship between money creation process and banking performance for Tunisian listed banks, particularly in the context of increased economic policy uncertainty.Design/methodology/approachIn the relevant literature, there are two theories of money creation. The theory of money creation out of nothing, by using the central bank for refinancing and the theory of financial intermediation, from which money creation is made from preexisting savings. In this paper, the authors utilize a panel data for a sample composed of 11 Tunisian banks during the period of study from 1999 to 2019.FindingsThe study’s empirical analysis show that both forms of money creation have a positive impact on bank profitability as measured by the return on assets (ROA) and return on equity (ROE) ratios. However, the same analysis shows that the channel of money creation out of nothing is the most profitable for banks. Also, the authors show that economic policy uncertainty negatively influences the relationship between money creation and banking profitability only when credit creation is derived from savings.Originality/valueThis paper contributes to the literature by explaining the nexus between money creation and Tunisian banking performance which depends on the implementation of stable and conducive economic and political environment. Also, this link requires the implementation of monetary measures to encourage savings and develop an efficient capital market and judicious monetary policy enabling the central bank to inject more liquidity into the economy.
The effect of uncertainty on the information content of term spread and its components
Authors: Kim Jun Sik 
Published: May 2021

Purpose
This paper aims to investigate the impact of uncertainty on the predictive power of term spread and its components for future stock market returns and economic activity in Korea and the USA. This paper finds that the stock market’s expected excess return and growth of economic activity are positively related to the risk-neutral expectation, one of the term spread’s components, particularly during high uncertainty periods. These findings are consistent with the importance of the monetary policy by the central bank in a high uncertainty environment created by unexpected shocks. The results are robust to alternate definitions of high uncertainty periods.

PurposeThe role of data analytics is significantly important in manufacturing industries as it holds the key to address sustainability challenges and handle the large amount of data generated from different types of manufacturing operations. The present study, therefore, aims to conduct a systematic and bibliometric-based review in the applications of machine learning (ML) techniques for sustainable manufacturing (SM).Design/methodology/approachIn the present study, the authors use a bibliometric review approach that is focused on the statistical analysis of published scientific documents with an unbiased objective of the current status and future research potential of ML applications in sustainable manufacturing.FindingsThe present study highlights how manufacturing industries can benefit from ML techniques when applied to address SM issues. Based on the findings, a ML-SM framework is proposed. The framework will be helpful to researchers, policymakers and practitioners to provide guidelines on the successful management of SM practices.Originality/valueA comprehensive and bibliometric review of opportunities for ML techniques in SM with a framework is still limited in the available literature. This study addresses the bibliometric analysis of ML applications in SM, which further adds to the originality.
The role of events and affect in perceived organizational support: a within-person approach
Authors: Woznyj Haley M. , Shanock Linda R. , Heggestad Eric D. , Banks George C. 
Published: May 2021

PurposeThe purpose is to understand how affective events employees experience at work, and emotions those events elicit, influence within-person fluctuations in perceived organizational support (POS). The authors explore the possibility of socioemotional needs as a boundary condition of the effects. They integrate affective events theory with organizational support theory to develop their arguments.Design/methodology/approachUsing a diary study method, 55 working adults responded to three surveys per day for ten days (876 total datapoints).FindingsThe results suggest POS fluctuates daily. Furthermore, workplace affective events are significantly related to discrete emotions (happiness and anger), which are significantly related to fluctuations in POS. Indirect effects were generally stronger when socioemotional needs were high compared to low, though the moderation was not statistically significant.Research limitations/implicationsThe authors extend organizational support theory by integrating affective events theory; they highlight the role of affective events and transient emotion in relation to momentary changes in POS and explore socioemotional needs as a moderator of those relationships.Practical implicationsOrganizations can be mindful of employees' daily experiences when considering how to foster POS; minimizing negative affective events and maximizing supportive affective events may enhance POS.Originality/valueThis study is the first to consider predictors of short-term fluctuations in POS. Moreover, the authors integrate affective events and discrete emotions to consider the role of affect in organizational support theory.
Electromagnetic and microwave absorption properties of MWCNTs based polymer nanocomposites
Authors: Geeri Satish , Kolakoti Aditya 
Published: May 2021

Purpose
The purpose of the present work is to fabricate composite with strong absorbing nature and with more strength. The usage of wireless communication is increasing day by day, electromagnetic absorbing material is required to reduce this pollution. In the present experimental investigation, composites were fabricated for zero and 45° fiber orientation and as a filler material of Multiwall Carbon Nanotubes (MWCNTs) for the proposed percentage in the composites. Microwave absorbing properties were investigated for both perfect electric conductor (PEC)-backed composites and without PEC-backed composites.

Design/methodology/approach
The electromagnetic absorbing performance was analyzed based on complex permeability, complex permittivity, dielectric tangent and magnetic tangent losses. The experimentation was done by Vector Network Analyzer in the frequency range of 8.2 to 12.4 GHz by X-band. The surface morphological study was done. The mechanical and thermal properties are also investigated for these composites.

Findings
By investigating the experimental values, the induced percentage of MWCNTs and PEC of composites affects the electromagnetic and microwave absorption properties of the composites. The microwave absorption properties improved when the composites were able to absorb wide bandwidth and low reflection loss. The best results are obtained for PEC-backed composites for 5%, which is about −43.56 dB at 11.1 GHz compared to without PEC-backed composites. The reflection loss is developed by the dielectric loss initiated from MWCNTs and by PEC.

Originality/value
To the best of the authors’ knowledge, no work was reported on hand lay-up method and PEC-backed composites in electromagnetic absorption properties with regression analysis.
Relationship between biochemical markers and measles viral load in patients with immunologically naive cases and secondary vaccine failure: LDH is one of the potential auxiliary indicators for secondary vaccine failure
Authors: Kurata Takako , Kanbayashi Daiki , Komano Jun , Motomura Kazushi 
Published: May 2021

AbstractThis study investigated the correlation between biochemical markers and viral load among 38 measles cases, including 15 immunologically naive patients and 23 patients with secondary vaccine failure (SVF). We examined four biochemical markers, namely, aspartate aminotransferase, alanine aminotransferase, C‐reactive protein, and lactate dehydrogenase (LDH) and their relationship between virus genome copy numbers in peripheral blood mononuclear cells (PBMCs) and throat swabs as well as the concentration of measles‐specific IgG. Although viral genome copies in both clinical specimens showed a significant correlation with specific IgG concentration, they had a higher correlation in PBMCs (Pearson's product‐moment correlation coefficient, −0.662; p < .0001) than in throat swabs (Spearman's rank correlation coefficient, −0.443; p = .0078). The viral load in PBMCs also significantly correlated with LDH values (correlation coefficient, 0.360; p = .036). Thus, the serum LDH level might be a potential auxiliary indicator to distinguish immunologically naive patients with measles from those with SVF.
Tree species mixing reduces biomass but increases length of absorptive fine roots in European forests

Published: May 2021

Abstract

Mixed‐species forests often enhance the provision of ecosystem functions, both above‐ and below‐ground. Several of these effects are mediated by the amount and spatial distribution of tree tissues. However, previous studies on tree diversity effects on fine‐root biomass (FRB) have returned inconsistent results and did not distinguish between absorptive and transport fine roots. Furthermore, owing to the lack of species‐specific data, it is not well understood whether complementarity or selection effects contribute more to these mixing effects.

Here, we analysed tree species mixing effects on fine‐root traits while considering the respective tree species contributions and root functional types. Specifically, we tested whether tree species mixing increases FRB and root length density (RLD) and results in vertical root stratification. We quantified FRB and RLD in 30‐cm deep soil profiles for 13 tree species in mixed and pure stands across four widespread European forest types. The differentiation of different fine‐root species in mixtures allowed us to disentangle complementarity and selection effects.

Across all sites, mixtures supported on average less FRB than pure stands, which was reflected in negative complementarity and selection effects. RLD of absorptive fine roots did not change across the soil profile and even increased in the topsoil, which was associated with positive complementarity effects. There was no evidence for vertical root stratification. Conifer proportion, which was mainly associated with selection effects, dampened net diversity effects. Root functional type further influenced tree species mixing effects.

Synthesis. Despite the underyielding of FRB in mixtures, overall soil occupation by absorptive fine roots (RLD) did not decrease in mixtures, pointing to morphological root trait adaptations associated with higher resource‐use efficiency. Increased RLD in the most nutrient‐rich layer in mixtures further indicates complementary interactions among species and a greater resource uptake capacity. This work illustrates that considering only one aspect of trait‐functioning relationships, for example, root biomass, may not capture the full effect of plant diversity on ecosystem functioning. The integration of a larger range of relevant traits is required. Moreover, traditional classification of fine roots based on the 2‐mm diameter cut‐off may obscure responses of roots to environmental changes.
Analysing the impacts of Universal Basic Income in the changing world of work: Challenges to the psychological contract and a future research agenda

Published: May 2021

AbstractTechnological developments within advanced economies are impacting organisations and working lives. With the advent of ‘Industry 4.0’, Universal Basic Income (UBI) is being cast as a potential ‘buffer’—a social safety net—to the restructuring of organisations, jobs, and economies that are already underway. The Covid‐19 pandemic is providing an additional impetus as governments instigate similar safety nets as employment falls in the wake of the virus. To date, much of the debate concerning UBI has taken place in disciplines outside the auspices of Human Resource Management with most commentary occurring within the spheres of economics and social policy. This conceptual study is one of the first within the human resource management (HRM) field to address the potential impacts of UBI on orientations to work and the management of employees. To do this, we focus on a central underpinning theory within HRM, the psychological contract and how this might be affected by its introduction. Finally, a research agenda is developed that provides options by which we might explore the implications of UBI for the practice of HRM when and if such schemes are implemented.

SummaryGrapevine (Vitis vinifera) is a reservoir of fungal endophytes that may affect its growth, health status and grape production. Although there is growing interest in comparing fungal communities of mainly red grape varieties across various factors using only high‐throughput sequencing, the small‐scale mycobiome variations in geographically close vineyards need further examination. We aimed to characterize the fungal microbiome of the above‐ground tissues of V. vinifera cv. Furmint in different plant parts, seasons and sites using culture‐dependent and culture‐independent methods, and in planta fluorescent microscopic visualization techniques. Samples were collected from four sites of the Tokaj wine region in Mád and two reference sites in Eger, Hungary, across different seasons for 2 years. Fungal endophytes of young and mature leaves, flowers and grape bunches were collected at different phenological stages. Based on each technique, Aureobasidium pullulans, Cladosporium spp. and the complex species Alternaria alternata dominated the community at every site, season and plant organ. We found no significant difference among communities in distinct neighbouring vineyards, nor when compared with the distant reference sites. We can conclude that the different shoot parts of the Furmint grapevines harbour a common core group of fungal community in these regions.

AbstractBackgroundTo investigate the survival benefit of concurrent chemoradiotherapy (CCRT) for patients with locally advanced esophageal squamous cell carcinoma (ESCC) during the years of intensity‐modulated radiotherapy (IMRT).MethodsMedical records of 1089 patients with ESCC who received IMRT from January 2005 to December 2017 were retrospectively reviewed. A total of 617 patients received CCRT, 472 patients received radiotherapy (RT) alone. Propensity score matching (PSM) method was used to eliminate baseline differences between the two groups. Survival and toxicity profile were evaluated afterward.ResultsAfter a median follow‐up time of 47.9 months (3.2–149.8 months), both overall survival (OS) and progression‐free survival (PFS) of the CCRT group were better than those of the RT alone group, either before or after PSM. After PSM, the 1‐, 3‐, and 5‐year OS of RT alone and CCRT groups were 59.0% versus 70.2%, 27.7% versus 40.5% and 20.3% versus 33.1%, respectively (p < 0.001). The 1‐, 3‐, and 5‐year PFS were 39.4% versus 49.0%, 18.3% versus 30.4% and 10.5% versus 25.0%, respectively (p < 0.001). The rates of ≥ grade 3 leukopenia and radiation esophagitis in the CCRT group were higher than that of RT alone group (p < 0.05). There was no significant difference in the probability of radiation pneumonitis between the two groups (p = 0.167). Multivariate Cox analysis indicated that female, EQD2 ≥60 Gy and concurrent chemotherapy were favorable prognostic factors for both OS and PFS.ConclusionsConcurrent chemotherapy can bring survival benefits to patients with locally advanced ESCC receiving IMRT. For patients who cannot tolerate concurrent chemotherapy, RT alone is an effective alternative with promising results.
