Human activity recognition in WBAN using ensemble model
Authors: Boga Jayaram , V. Dhilip Kumar 
Published: March 2022

Purpose
For achieving the profitable human activity recognition (HAR) method, this paper solves the HAR problem under wireless body area network (WBAN) using a developed ensemble learning approach. The purpose of this study is,to solve the HAR problem under WBAN using a developed ensemble learning approach for achieving the profitable HAR method. There are three data sets used for this HAR in WBAN, namely, human activity recognition using smartphones, wireless sensor data mining and Kaggle. The proposed model undergoes four phases, namely, “pre-processing, feature extraction, feature selection and classification.” Here, the data can be preprocessed by artifacts removal and median filtering techniques. Then, the features are extracted by techniques such as “t-Distributed Stochastic Neighbor Embedding”, “Short-time Fourier transform” and statistical approaches. The weighted optimal feature selection is considered as the next step for selecting the important features based on computing the data variance of each class. This new feature selection is achieved by the hybrid coyote Jaya optimization (HCJO). Finally, the meta-heuristic-based ensemble learning approach is used as a new recognition approach with three classifiers, namely, “support vector machine (SVM), deep neural network (DNN) and fuzzy classifiers.” Experimental analysis is performed.

Design/methodology/approach
The proposed HCJO algorithm was developed for optimizing the membership function of fuzzy, iteration limit of SVM and hidden neuron count of DNN for getting superior classified outcomes and to enhance the performance of ensemble classification.

Findings
The accuracy for enhanced HAR model was pretty high in comparison to conventional models, i.e. higher than 6.66% to fuzzy, 4.34% to DNN, 4.34% to SVM, 7.86% to ensemble and 6.66% to Improved Sealion optimization algorithm-Attention Pyramid-Convolutional Neural Network-AP-CNN, respectively.

Originality/value
The suggested HAR model with WBAN using HCJO algorithm is accurate and improves the effectiveness of the recognition.
A bibliometric analysis of the structure and trends of customer engagement in the context of international marketing
Authors: Srivastava Mukta , Sivaramakrishnan Sreeram 
Published: March 2022

PurposeResearch in customer engagement (CE) has gained momentum in the last decade, thanks to its growing popularity among scholars and practitioners. The Marketing Science Institute (MSI), for instance, has been continually listing CE as part of its Tier I research priorities since 2010. CE scholars have also studied the construct in the international marketing context. Hofstede's characterization of cultures as either individualist or collectivist helped scholars explain the need for different CE strategies across countries, and the domain seems to be evolving ever since. The ever-growing interest of CE scholars in the international market and cross-cultural scenarios requires a comprehensive and scientific review of the literature. Using bibliometric analysis, this study fills this critical gap by mapping the intellectual structure of CE research in the context of international marketing and provides future research directions to scholars in this domain.Design/methodology/approachThe authors have used VOSviewer and Biblioshiny software packages to conduct a bibliometric analysis of 109 articles in the domain.FindingsThe major findings include the most influential countries, journals, articles and authors, the different research streams and their development and the future research directions in the domain. When CE is considered in an international marketing context, four broad themes emerged. The first theme is about differences in customer engagement behaviors across cultures. The second theme is about the development of CE and related constructs. The third theme relates to how brands have used CE and CBE (customer brand engagement) across different international contexts. The fourth theme is all about the conceptual and methodological support for the study of CE.Originality/valueThis study is a novel attempt at providing a comprehensive bibliometric analysis of CE research in the international marketing context, using a combination of VOSviewer and Biblioshiny software packages.
Corruption, R&D and performance: firm-level evidence from Latin America
Authors: Viglioni Marco Túlio Dinali , Ferreira Manuel Portugal , Aveline Carlos Eduardo Stefaniak , Alcântara Juciara Nunes de 
Published: March 2022

PurposeThis study aims to investigate how firms' perceived level of corruption moderates the relationship between Research and Development (R&D) investments and firms' financial performance.Design/methodology/approachThe study has used dynamic panel data for local private and public firms from Latin American countries (Brazil, Chile, Mexico and Peru) during 2012–2019. The unbalanced panel was estimated using generalized method of moments (GMM) and instrumental variables (IVs) to account for endogeneity issues.FindingsThe results showed that corruption has a direct and positive effect on firms' financial performance. Moreover, while firms' financial performance increases in the presence of corruption, the authors' findings suggest that corruption negatively moderates the relationship between R&D investments and firms' financial performance. This finding exposes the debate “grease the wheels” once corruption appears to work much more like sand than grease on more innovative firms. Finally, the authors observed a negative effect of long-term R&D investments on firms' performance, indicating that high levels of corruption harm even more long-term innovative activities.Research limitations/implicationsThe authors have delimited the scope to firms from four Latin American countries, and thus, the generalization to other countries, from Latin America or other emerging countries, needs to be made with caution. Furthermore, the authors used the corruption perception index (CPI) to assess the extent of corruption and, apparently, using a single measure may limit the understanding. Future research may deepen the authors' comprehension by exploring the effects of the different practices or types of corruption.Practical implicationsThe authors' findings have challenging policy implications denoting policymakers need to prioritize the institutional quality to reduce corruption and foster firms' R&D investments.Originality/valueThe paper has adopted a unique firm-level dataset from an underresearched region. This enriches a long-standing debate by providing new insights of corruption effects in Latin America. Therefore, the authors provided new evidence of the moderating relationship between corruption and R&D investments on more innovative firms' performance.
Stakeholder management challenges in mega construction projects: critical success factors
Authors: Mashali Ayman , Elbeltagi Emad , Motawa Ibrahim , Elshikh Mohamed 
Published: March 2022

Purpose
The construction industry is facing massive challenges due to the huge construction development, and stakeholder management (SM) practices, especially on megaprojects. The purpose of this paper is to investigate critical success factors (CSFs) encountered by key construction stakeholders to enhance SM practices on mega construction projects (MCPs).

Design/methodology/approach
A questionnaire survey is carried out among the most important construction companies in Qatar. Three steps are used to finalize and evaluate the questionnaire before proceeding with the full survey, validity, pretesting and pilot study. Quantitative data analysis was conducted using the Statistical Package for Social Science software.

Findings
This paper identifies the key factors contributing to improving SM performance in MCPs; none of these is uncommon, but here they come together in a more integrative way.

Research limitations/implications
The limitations related to this research are briefly outlined as follows: the research was carried out in the State of Qatar. So, the findings are limited to the Qatari construction industry. The construction industry in Qatar is different from other countries where public projects have the priority to develop the infrastructure of the country prior to the world cup competition. The scope of this research is limited to MCPs. The impact of low awareness and knowledge of SM is not considered. However, the study is still reasonable and fortunately suitable to evaluate SM in MCPs.

Practical implications
Identifying these factors is expected to assist project participants in MCPs in improving projects’ performance and completing construction within the predefined time and cost.

Originality/value
This study makes a significant contribution through identifying the CSFs that lead to develop efficient SM in MCPs. Moreover, the research findings are important for project stakeholders, organizations, contractors, engineers and local authorities who implement SM in MCPs. Moreover, it will enhance the application of SM practices in construction megaprojects and allow project key stakeholders to place emphasis on tackling the crucial challenges identified in this research.
Institutional factors and the timing of land development: a survival analysis applied to the GZM Metropolis in Poland
Authors: Reyman Katarzyna , Maier Gunther 
Published: March 2022

PurposeThe purpose of the article is to improve the understanding of the role of institutional factors in real estate development. The authors take into account zoning (existence and type), type of right of disposal and type of buyer and seller of property in a multivariate econometric estimation. Dependent variable of the analysis is the time between acquisition of empty land and the application for a building permit, a period when many important development decisions have to be made. This indicator is closely related to debated phenomena like land hording and speculation.Design/methodology/approachThe authors estimate a Cox proportional hazard model with the time between acquisition and application for a building permit as dependent variable and institutional indicators and a number of control variables as explanatory variables. Study area is the GZM Metropolis in the South of Poland. This region shows enough variability in institutional arrangements to allow for this type of analysis.FindingsThe analysis shows that institutional factors significantly influence the real estate development process. In areas that have not issued a zoning plan, the period until the building permit application is significantly longer. When the state is involved in a transaction (as purchaser or seller), it also takes longer until the building permit application is submitted. Although the instrument is usually intended to speed up development, perpetual usufruct implies a longer period until building permit application. Because of the results the authors get for control variables and for robustness checks, the authors are confident of the results of the analysis.Originality/valueTo the authors’ knowledge, this is the first study that deals with the question how institutional factors influence the timing of real estate development. By using data for a region in Poland, the authors also add to knowledge about real estate development in CEE countries.
Does board-level employee representation impact firms’ value? Evidence from the European countries
Authors: Silva Sónia , Silva Armando , Machado Ricardo Bahia 
Published: March 2022

Purpose
Using, for the first time, a sample of European listed firms from 30 countries with different legal regimes of board-level employee representation (BLER), the purpose of this paper is to examine the impact of BLER on firms’ value of European public companies, where employee representation is voluntary or imposed by law depending on the country of origin.

Design/methodology/approach
Using a difference-in-differences approach and a matching procedure, the authors analyze the impact of BLER on firms' value.

Findings
The results of this paper suggest that BLER adopted voluntarily affects positively firms’ value comparing to a group of firms where employee representation is in some way mandatory. Moreover, the findings of this paper show that firms from countries where BLER is not imposed by law tend to pay higher dividends. Nevertheless, the evidence presented in this paper only holds for low levels of employee representation on the board.

Research limitations/implications
This research not only provides some evidence in favor of the codetermination on corporate governance but also offers new avenues for discussing the conditions necessary for codetermination to be effective, especially the level of employees' participation on board.

Practical implications
This study provides to policymakers new insights for them to gain perspective, analyze and decide if codetermination is a useful tool to improve firms’ performance or at least in what conditions it should be applied.

Social implications
This study incentives the discussion of the proper way to include workers in firms’ boards with expected benefits on firms’ performance, economies and societies.

Originality/value
This paper provides evidence of a positive (but limited) impact on firms’ value derived from voluntary codetermination.
Leadership and its influence on employee absenteeism: a qualitative review
Authors: Løkke Ann-Kristina 
Published: March 2022

PurposeThe purpose of this paper is to provide an overview of the last 50 years of empirical research on leaders' influence on employee absenteeism. Furthermore, the aim is to direct future management research by identifying what is still undiscovered regarding areas such as leadership concepts, measurements of absenteeism, methodology and country-specific contexts of the studies.Design/methodology/approachThis is a qualitative review which is suitable as the literature on leadership and employee absenteeism is still emergent and characterized by heterogeneity in terms of operationalization of absenteeism and leadership concepts, respectively, as well as types of analyses.FindingsThis review identifies different aspects of leadership affecting employee absence, i.e. leadership behaviours (i.e. task, relational, change, passive), leadership styles, leaders' social modelling and attitudes, and leaders' management of health and absence. Furthermore, a number of gaps in extant research are identified as well as a research agenda is provided.Originality/valueThis review is the first of its kind and hence contributes more profound insights into leaders' influence on employee absenteeism. Leaders as a factor explaining employee absenteeism have only played a minor role, in large theoretical contributions, and the exact behaviour and style is not elaborated much in the literature. Thus, this paper provides practical and theoretical considerations over the role of leaders in shaping employee absenteeism.
Wisdom in higher education: discussions with education academics utilising theBhagavad Gita
Authors: Rampal Shelly , Smith Sue Erica , Soter Anna 
Published: March 2022

PurposeIn this paper we seek to provide insight as to how wisdom is, or might be, perceived and enacted in Higher Education contexts. Selected constructs of wisdom derived from theBhagavad Gitaprovided a platform from which seven invited College of Education faculty participants considered their own framings of wisdom in the contexts of their own professional and personal lives.Design/methodology/approachThis case study has drawn upon constructs of wisdom proffered by key Indian scholars who share this epistemological stance. A three-stage process was deployed, comprised of an introductory close-ended survey, an open-ended questionnaire to determine personalised insights and semi-structured interviews to clarify and member-check the data.FindingsThe participant academics' reflections offered a convergence on rich potential to pursue wisdom in Education and promote ethics, integrity, skilful action and inclusion. Furthermore, a general concern among the group of seven faculty who participated, was a perceived lack of humility in academia.Research limitations/implicationsA sample of seven participants precludes generalizable findings. Some ambiguities of constructs like “Love of God”, “Duty” and “Inner peace” provided space for participants to interrogate their own understandings.Originality/value“Wisdom” in Higher Education has not been an explicit topic of research until relatively recently. Based on the present study, which entailed in-depth written responses to questions that asked faculty respondents about their perceptions of the place and role of “wisdom” in Higher Education settings, we can however, suggest possible directions for wisdom-focused research in pluricultural Higher Education contexts.

Published: March 2022

AbstractRhodococcus equiis the causative agent of pyogenic pneumonia in foals, and a virulence‐associated protein A (VapA) encoded on the pVAPA virulence plasmid is important for its pathogenicity. In this study, we analyzed the virulence of R. equi strain U19, originally isolated in the Netherlands in 1997 and the genetic characteristics of the pVAPA_U19 plasmid. U19 expressed VapA that was regulated by temperature and pH and underwent significant intracellular proliferation in macrophages. The restriction fragment length polymorphism of pVAPA_U19 digested with EcoRI was similar to that of pREAT701 (85 kb Type I) harbored by R. equi ATCC33701, although the band pattern at 10–20 kb differed. Whole‐genome sequencing showed that pVAPA_U19 was 51,684 bp in length and that the vapA pathogenicity island region and the replication/participation were almost identical to those in pREAT701. By contrast, the open reading frames (ORF26–ORF45) genes of pREAT701 (approximately 29,000 bp) were absent from pVAPA_U19. In this lacking region, mobility (MOB) genes, such as relaxase, which allow conjugative DNA processing, and the mating pair formation (MPF) genes, which are a form of the Type IV secretion system and provide the mating channel, were present. Coculture between U19 and five different recipient strains (two plasmid‐cured strains and three cryptic plasmid‐harboring strains) demonstrated that pVAPA_U19 could not support conjugation. Therefore, pVAPA_U19 does not differ significantly from the previously reported pVAPA in terms of virulence and plasmid replication and maintenance but is a nonmobilizable plasmid unable to cause conjugation because of the absence of genes related to MOB and MPF.

AbstractHyperglycaemia is a major cause of pathophysiological processes such as oxidative stress, inflammation, and apoptosis in diabetes. Dapagliflozin (DAPA), a novel hypoglycaemic drug, has been shown to have anti‐apoptotic, anti‐inflammatory, and antioxidant effects in multiple experimental studies. In this study, we investigated the protective effects of DAPA in the hyperglycaemic condition to identify associated molecular mechanisms. human umbilical vein endothelial cells (HUVEC) endothelial cells were treated with 40 mM glucose for 72 h to establish an in vitro high glucose (HG) condition model, and then additional groups co‐treated with or without DAPA before glucose treatment. Then, cell viability, reactive oxygen species (ROS), pro‐inflammatory cytokines (IL‐6 and TNF‐α), apoptosis, and SIRT1 expression were measured. The results showed that DAPA pretreatment resulted in increased cell viability. Additionally, DAPA pretreatment decreased endothelial ROS, IL‐6, and TNF‐α levels in endothelial cells subjected to HG conditions. Moreover, DAPA pretreatment significantly prevented HG‐induced apoptosis and caspase‐3 activity in HUVECs. Furthermore, DAPA increased the expression of SIRT1, PGC‐1α, and increased the phosphorylation levels of AMPK (p‐AMPK) in a set of HG conditions in HUVECs. However, the endothelial protective effects of DAPA were abolished when cells were subjected to the SIRT1 inhibitor (EX‐527) and AMPK inhibitor (Compound C). These findings suggest that DAPA can abrogate HG‐induced endothelial cell dysfunction by AMPK/SIRT1 pathway up‐regulation. Therefore, suggesting that the activation of AMPK/SIRT1 axis by DAPA may be a novel target for the treatment of HG‐induced endothelial cell injury.

AbstractBackgroundIncarcerated individuals who experience pregnancy or childbirth in correctional facilities face unique considerations for obstetric care and consequently are at greater risk of adverse maternal and fetal outcomes.ObjectivesTo characterise patient experiences regarding pregnancy and childbirth during incarceration via qualitative synthesis.Search strategyMedline‐OVID, EMBASE, CINAHL, Sociological Abstracts, Social Work Abstracts, Web of Science, Scopus and PsycInfo were systematically searched from inception to 24 December 2020. Supplementary searches were performed using the Scopus database.Selection criteriaOnly original, peer‐reviewed literature was examined. Eligible studies were assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research.ResultsAfter screening 4173 original database citations, 24 studies that met inclusion criteria were included and analysed via thematic analysis. The 24 studies included perspectives from 645 female patients who had experienced incarceration, 69 healthcare providers and 70 prison staff. Key patient‐reported concerns for the well‐being of pregnant individuals during incarceration included mental health challenges, dehumanisation of prenatal care and delivery, lack of privacy, stigma, psychological trauma, lack of emotional support and shackle usage during pregnancy and/or labour. The studies reported a lack of support for patients to access female correctional officers or guards, privacy during intimate examinations, timely medical care and support for breastfeeding. Above all, the psychological trauma of separation from one's newborn after birth was of utmost devastation.ConclusionsOur systematic review highlights the dire need for accountability and interventions to improve pregnancy and childbirth care for incarcerated individuals.Tweetable abstractThis systematic review describes lived experiences of pregnancy & childbirth during incarceration, including dehumanisation, psychological trauma, and use of shackles.
