Electrocardiogram stream level correlated patterns as features to classify heartbeats for arrhythmia prediction
Authors: Al-Yarimi Fuad Ali Mohammed , Munassar Nabil Mohammed Ali , Al-Wesabi Fahd N. 
Published: October 2020

PurposeDigital computing and machine learning-driven predictive analysis in the diagnosis of non-communicable diseases are gaining significance. Globally many research studies are focusing on developing comprehensive models for such detection. Categorically in the proposed diagnosis for arrhythmia, which is a critical diagnosis to prevent cardiac-related deaths, any constructive models can be a value proposition. In this study, the focus is on developing a holistic system that predicts the scope of arrhythmia from the given electrocardiogram report. The proposed method is using the sequential patterns of the electrocardiogram elements as features.Design/methodology/approachConsidering the decision accuracy of the contemporary classification methods, which is not adequate to use in clinical practices, this manuscript coined a new dimension of features to perform supervised learning and classification using the AdaBoost classifier. The proposed method has titled “Electrocardiogram stream level correlated patterns as features (ESCPFs),” which takes electrocardiograms (ECGs) signal streams as input records to perform supervised learning-based classification to detect the arrhythmia scope in given ECG record.FindingsFrom the results and comparative reports generated for the study, it is evident that the model is performing with higher accuracy compared to some of the earlier models. However, focusing on the emerging solutions and technologies, if the accuracy factors for the model can be improved, it can lead to compelling predictions and accurate outcome from the process.Originality/valueThe authors represent complete automatic and rapid arrhythmia as classifier, which could be applied online and examine long ECG records sequence efficiently. By releasing the needs for extraction of features, the authors project an application based on raw signals, one result to heart rates date, whose objective is to lessen computation time when attaining minimum classification error outcomes.

Authors: D'Agostino Antonella , Rosciano Monica , Starita Maria Grazia 
Published: October 2020

PurposeThis paper aims to apply a multidimensional approach to assessing the financial well-being of European countries.Design/methodology/approachFinancial well-being is a very complex phenomenon to measure because it is composed of different dimensions. Therefore, this paper uses a multidimensional and fuzzy methodology to assess financial well-being in Europe. The financial well-being fuzzy indicator was calculated using European Quality of Life Survey data.FindingsFinancial well-being is heterogeneous across European countries. This evidence is confirmed both at the level of overall financial well-being and at the level of sub-indices. The degree of financial well-being is not directly related to wealth as traditionally measured (i.e. GDP), but shows some correspondence with socio-economic characteristics of the population and with governance and cultural elements of a country.Practical implicationsUnderstanding financial well-being could help financial institutions to transition from a one-size-fits-all approach to a more tailored approach when they provide financial services and could help policy makers to consider financial well-being when they decide how and where to allocate public spending.Originality/valueTo the best of authors’ knowledge, this study is the first to employ a fuzzy methodology for the analysis of financial well-being in Europe.
Tourists’ perceptions regarding the use of anthropomorphic robots in tourism and hospitality
Authors: Christou Prokopis , Simillidou Aspasia , Stylianou Maria C. 
Published: October 2020

Purpose
Amidst the COVID-19 outbreak, service organizations rushed to deploy robots to serve people in quarantine, again igniting the ongoing dispute regarding robots in tourism. This study aims to investigate tourists’ perceptions regarding the use of robots and, more specifically, anthropomorphic robots in the tourism domain.

Design/methodology/approach
A qualitative inquiry was used to delve deep into the issue of tourists’ perceptions regarding the usage of anthropomorphic robots in tourism, with a total number of 78 interviews with tourists being retained in the study.

Findings
The findings reveal that tourists favor the use of anthropomorphic robots over any other type of robot. The use of anthropomorphic robots in tourism may result in an overall enhanced experiential value. Even so, informants also expressed frustration, sadness and disappointment vis-à-vis the use of robots in a human-driven industry.

Research limitations/implications
A conceptual continuum of tourists’ perceptions and concerns over the use of robots is presented that can guide future studies. Tourism stakeholders may look at the possibility of incorporating carefully designed anthropomorphic robots in key service positions, but should not give the impression that robots are replacing the human face of the organization.

Practical implications
Tourism stakeholders may look at the possibility of incorporating carefully designed anthropomorphic robots in key service positions, but should not give the impression that robots are replacing the human face of the organization.

Originality/value
Tourism organizations that make use of robots run the risk of being perceived as nonanthropocentric. This leads to the conclusion that anthropomorphism could be used but should not replace the sector’s anthropocentrism. The study conveys tourists’ concerns over technological (robot) determinism.
Wage premia for skills: the complementarity of cognitive and non-cognitive skills
Authors: Palczyńska Marta 
Published: October 2020

PurposeThe main purpose of this paper is to assess the degree of complementarity between cognitive skills and non-cognitive skills, and to evaluate their joint impact on individual wages.Design/methodology/approachThe author uses a survey representative of the Polish working-age population with well-established measures of cognitive and non-cognitive skills.FindingsNon-cognitive skills are important in the labour market, not only as separate factors that influence wages, but as complements to cognitive skills. Specifically, the analysis showed that the more neurotic an individual is, the lower his or her returns to cognitive skills are. Social skills were not shown to be complementary to cognitive skills in Poland unlike the recent results in the United States.Originality/valueTo the best of author's knowledge, this is the first study to provide evidence that neurotic individuals have lower returns to cognitive skills. It also tests the existence of the complementarity between social and cognitive skills.
Consumers’ usage and adoption of e-pharmacy in India
Authors: Srivastava Mallika , Raina Madhur 
Published: October 2020

Purpose
This paper aims to identify and empirically validate the various factors for adoption, usage and intention to recommend e-pharmacy for purchasing medications by consumers.

Design/methodology/approach
Based on constructs from well-established theoretical models, the technology acceptance model, extended unified theory of acceptance and use of technology and self-determination theory, a model was proposed for the study. The model was validated with a sample size of 184 respondents using partial least squares method and factor analysis to establish and validate relationships among the various identified constructs.

Findings
The results show that performance expectancy, effort expectancy, social influence and hedonic motivation have a positive co-relation with adoption of e-pharmacy and the intention to recommend. The results depict that gender and educational background have no correlation toward adoption and intention to recommend e-pharmacies for purchasing medicines in India.

Research limitations/implications
This research comes along with a geographic limitation of the sample size. The research was conducted in an urban suburb city of Bengaluru, India.

Practical implications
At an academic level, this research will provide interesting insights for exploring adoption and usage intention of consumers toward e-pharmacy. At a managerial level, this empirically supported study will provide insights into the relationship among the various constructs and the consumers’ motivation toward adoption and usage intention of e-pharmacy.

Originality/value
This research is the first of its form which uses constructs from the technology acceptance model, extended unified theory of acceptance and use of technology and self-determination theory in the online healthcare space to understand consumer usage behavior.

Authors: Andreoli Parker Morse , Klar Hans W. 
Published: October 2020

PurposeThe purpose of this study is to examine how a school leadership team in a rural, high-poverty elementary school learned to lead continuous school improvement in a research–practice partnership.Design/methodology/approachThis case study draws on qualitative research methods, improvement science and Deming's notion of a system of profound knowledge to identify how members of the school leadership team understood and approached their school improvement work differently as a result of engaging in continuous improvement processes in a research–practice partnership.FindingsThe findings illustrate how engaging in continuous improvement processes in the research–practice partnership enhanced the leadership team members' capacities to prioritize and solve problems, incorporate multiple and diverse perspectives in problem-solving efforts and establish a culture of increased risk-taking and ownership of teaching and learning outcomes. In sum, the members of the leadership team became the drivers of their own change processes.Originality/valueThe findings provide insight into how leaders in rural, high-poverty schools can build capacity within their schools to meet the demand for increased student achievement by leading collaborative, continuous improvement processes grounded in improvement science in research–practice partnerships.

Authors: Caporale Guglielmo Maria , Plastun Alex 
Published: October 2020

PurposeThis paper explores abnormal price changes in the FOREX by using both daily and intraday data on the EURUSD, USDJPY, USDCAD, AUDUSD and EURJPY exchange rates over the period 01.01.2008–31.12.2018.Design/methodology/approachIt applies a dynamic trigger approach to detect abnormal price changes and then various statistical methods, including cumulative abnormal returns analysis, to test the following hypotheses: the intraday behaviour of hourly returns on overreaction days is different from that on normal days (H1), there are detectable patterns in intraday price dynamics on days with abnormal price changes (H2) and on the following days (H3).FindingsThe results suggest that there are statistically significant differences between intraday dynamics on days with abnormal price changes and normal days respectively; also, prices tend to change in the direction of the abnormal change during that day, but move in the opposite direction on the following day. Finally, there exist trading strategies that generate abnormal profits by exploiting the detected anomalies, which can be seen as evidence of market inefficiency.Originality/valueNew evidence on abnormal price changes and related trading strategies in the FOREX.

Published: October 2020

PurposeThe purpose of this paper is to analyse how entrepreneurial bricolage empowers smallholder commercial farming, from a family business perspective.Design/methodology/approachThe study employed a multiple case study design to analyse entrepreneurial bricolage in smallholder commercial farming in Uganda. It used multiple data collection methods and applied content analytical tchniques to establish cross-case correlations, patterns and relationships to aid in theory development and testing.FindingsThe study shows that entrepreneurial bricolage empowers smallholder commercialization through resource reallocation, improvization and prioritization as interconnected, self-reinforcing bricolage processes in smallholder farming. It provides evidence of how smallholder farms may not enact institutional limits, and overcome constraints imposed by their resource environments. It further reveals that smallholder commercial farms can be construed as family businesses given the interconnected relationship between farming business, family and smallholder farm(er).Research limitations/implicationsThe study was conducted in smallholder farms hence results may be used cautiously in other sectors and economies where resource environments are not structurally defined. However, it provides lessons for family businesses in developed countries particularly the micro- and small businesses. It also renders smallholder farming as a lucrative area for family business research.Originality/valueThis study deepens our understanding of bricolage in smallholder farming and provides a springboard for scholarship in enhancing smallholder commercialization. It proposes a model for entrepreneurial bricolage in smallholder commercial farming.
Mapping scientific profile and knowledge diffusion of Library Hi Tech
Authors: Kim Meen Chul , Feng Yuanyuan , Zhu Yongjun 
Published: October 2020

PurposeLibrary Hi Tech is one of the most influential journals that publish leading research in library and information science (LIS). The present study aims to understand the scholarly communication in Library Hi Tech by profiling its historic footprint, emerging trends and knowledge diffusion.Design/methodology/approachA total of 3,131 bibliographic records between 1995 and 2018 were collected from the Web of Science. Text mining, graph analysis and data visualization were used to analyze subject category assignment, domain-level citation trends, co-occurrence of keywords, keyword bursts, networks of document co-citation and landmark articles.FindingsFindings indicated that published research in the journal was largely influenced by the psychology, education and social domain as a unidisciplinary discipline. Knowledge of the journal has been disseminated into multiple domains such as LIS, computer science and education. Dominant thematic concentrations were also identified: (1) library services in academic libraries and related to digital libraries, (2) adoption of new information technologies and (3) information-seeking behavior in these contexts. Additionally, the journal has exhibited an increased research emphasis on mixed-method user-centered studies and investigations into libraries' use of new media.Originality/valueThis study provides a promising approach to understand scientific trends and the intellectual growth of journals. It also helps Library Hi Tech to become more self-explanatory with a detailed bibliometric profile and to identify future directions in editorship and readership. Finally, researchers in the community can better position their studies within the emerging trends and current challenges of the journal.
The bridging role of regional headquarters. Multinational companies in the Asia-Pacific region
Authors: Amann Bruno , Jaussaud Jacques , Schaaper Johannes 
Published: October 2020

PurposeLarge multinational companies (MNCs) are strongly formalized, often standardized and complex with multiple hierarchical levels. Over the past few decades, MNCs have strengthened their coordination and control systems by creating regional headquarters (RHQs). This study aims to investigate how MNCs rearticulate control dimensions at RHQs, to coordinate and exert control over subsidiaries in the Asia-Pacific region.Design/methodology/approachBased on a survey of 86 French MNCs in the Asia-Pacific region, this study applies a structural equation model to determine RHQs’ roles in the field of regional decision-making, coordination and control.FindingsLarge MNCs, with a significant presence in Asia, transfer coordination and control to RHQs, in a way that leads us to propose the use of the expression “regio-centralization.” RHQs become socialization hubs, where most regional decisions are taken and where international managers meet. MNCs mobilize at the same time expatriates, short-term assignees and local managers who intensively interact at RHQs. Thus, informal control at RHQs increases, partly substituting formal control by HQs. Smaller MNCs, without RHQs, on the contrary, base their control and coordination on the formalization of HQs-subsidiary relations, especially through strong reporting, in combination with centralized decision-making at HQs.Research limitations/implicationsThis study is based on MNCs from one specific country, France, and focuses only on the dynamic Asia-Pacific host region. Coordination and control in less dynamic regions may reveal different results.Originality/valueThis study leads to a better understanding of how large MNCs reorganize dispersed activities in the Asia-Pacific region by creating RHQs, where important control and coordination functions are relocated.
Instant messaging: a novel means of facilitating the participation of hard-to-reach groups in sensitive topic research
Authors: Dawson Jordan , Einion-Waller Alys , Jones Deborah 
Published: October 2020

PurposeAs society becomes ever more reliant on Internet technology for everyday communications, this paper explores the use of instant messaging (IM) in qualitative research. Discussed within the context of sensitive topic research with potentially hidden and hard-to-reach groups, the purpose of this paper is to discuss the value of adaptive and contemporary research approaches which facilitate participation on the terms of the participant.Design/methodology/approachReflecting on the data collection process from the primary authors’ PhD research, this paper critically considers some of the issues raised by IM-facilitated at semi-structured interviews.FindingsThis paper raises a number of issues, including how the perceived depth of participant response is influenced by their brevity, resultant of the space between parties which allows for considered and concise communication. This disconnect, created by the use of technology, also has implications for the power relations between researcher and participant and the ability to identify the non-verbal cues which communicate emotion and sentiment.Originality/valueThis paper highlights that whilst limited in some respects, an IM-facilitated interview provides a unique platform through which hidden and hard-to-reach groups may be empowered to participate in research, which they may usually avoid.
Strain-rate-dependent properties of short carbon fiber-reinforced acrylonitrile-butadiene-styrene using material extrusion additive manufacturing
Authors: Verbeeten Wilco M.H. , Lorenzo-Bañuelos Miriam , Saiz-Ortiz Rubén , González Rodrigo 
Published: October 2020

Purpose
The purpose of the present paper is to quantify and analyze the strain-rate dependence of the yield stress for both unfilled acrylonitrile-butadiene-styrene (ABS) and short carbon fiber-reinforced ABS (CF-ABS) materials, fabricated via material extrusion additive manufacturing (ME-AM). Two distinct and opposite infill orientation angles were used to attain anisotropy effects.

Design/methodology/approach
Tensile test samples were printed with two different infill orientation angles. Uniaxial tensile tests were performed at five different constant linear strain rates. Apparent densities were measured to compensate for the voided structure. Scanning electron microscope fractography images were analyzed. An Eyring-type flow rule was evaluated for predicting the strain-rate-dependent yield stress.

Findings
Anisotropy was detected not only for the yield stresses but also for its strain-rate dependence. The short carbon fiber-filled material exhibited higher anisotropy than neat ABS material using the same ME-AM processing parameters. It seems that fiber and molecular orientation influence the strain-rate dependence. The Eyring-type flow rule can adequately describe the yield kinetics of ME-AM components, showing thermorheologically simple behavior.

Originality/value
A polymer’s viscoelastic behavior is paramount to be able to predict a component’s ultimate failure behavior. The results in this manuscript are important initial findings that can help to further develop predictive numerical tools for ME-AM technology. This is especially relevant because of the inherent anisotropy that ME-AM polymer components show. Furthermore, short carbon fiber-filled ABS enhanced anisotropy effects during ME-AM, which have not been measured previously.
