Published: July 2021

AbstractWith the reduction in sequencing costs, studies become prevalent that profile the chromatin landscape for tens or even hundreds of human individuals by using ChIP/ATAC-seq techniques. Identifying genomic regions with hypervariable ChIP/ATAC-seq signals across given samples is essential for such studies. In particular, the hypervariable regions (HVRs) across tumors from different patients indicate their heterogeneity and can contribute to revealing potential cancer subtypes and the associated epigenetic markers. We present HyperChIP as the first complete statistical tool for the task. HyperChIP uses scaled variances that account for the mean-variance dependence to rank genomic regions, and it increases the statistical power by diminishing the influence of true HVRs on model fitting. Applying it to a large pan-cancer ATAC-seq data set, we found that the identified HVRs not only provided a solid basis to uncover the underlying similarity structure among the involved tumor samples, but also led to the identification of transcription factors pertaining to the similarity structure when coupled with a motif-scanning analysis.
Corporate governance, CEO turnover and say on pay votes
Authors: Omar Ayishat , Tang Alex P. , Cong Yu 
Published: July 2021

PurposeThe purpose of this study is to investigate how compensation committee structure or characteristic impacts say on pay (SOP) voting dissent and the impact of SOP dissent on chief executive officer (CEO) turnover.Design/methodology/approachThe authors use corporate governance and SOP data to test the relationships amongst variables. Additional analysis is performed using one-to-one propensity-score matched samples.FindingsThe authors find that firm-years with at least a female member present on the compensation committee are associated with lower SOP dissent. The authors find mixed results of the impact of SOP dissent on CEO turnover.Practical implicationsThis paper suggests that diversity on the compensation committee, particularly the presence of at least a female member on the committee, serves as an important determinant of SOP voting outcome in the USA. The paper provides policymakers and practitioners with insights into factors influencing SOP voting outcomes and implications of SOP dissent for firms.Originality/valueThe findings of this paper contribute to the corporate governance literature by enhancing the understanding of the role of the compensation committee as it relates to SOP dissent and effect of SOP dissent on CEO turnover.

Authors: Ferreras-Garcia Raquel , Sales-Zaguirre Jordi , Serradell-López Enric 
Published: July 2021

PurposeThe aim of this article is to provide evidence about how the acquisition of competencies through internships influence student learning process results, and about whether learning process results are affected by the gender differences, by considering two sustainable development goals (SDGs) of the 2030 United Nations’ Agenda: Gender Equality (SDG 5) and Quality Education (SDG 4).Design/methodology/approachThe study was carried out on a sample of 273 interns and their supervisors on the bachelor’s degree program in Tourism and Hospitality Management at the School of Tourism and Hospitality Management Sant Ignasi who carried out curricular internships during the 2016–2020 academic years. The university internship and mobility service sends supervisors a questionnaire, the purpose of which is to rate how well students have acquired the competencies and achieved the learning process results during their internship. The supervisors complete and return the questionnaire once the student has completed the internship.FindingsThe findings confirm that learning results appear to be positively influenced by certain competencies, especially personal ones such as orientation toward achievement and initiative and entrepreneurial spirit. Other results show the effect of the gender differences, as female students obtain better learning results than male students. Supervisors’ gender also seems to affect results.Practical implicationsThe research will help improve the design of internship-based programs of study.Originality/valueThe analysis provides an innovative research and contributes knowledge on the relation between competencies and learning results in the tourism and hospitality education sector in the field of internships and on the role of the gender dimension.

Authors: Bowers Alex J. , Krumm Andrew E. 
Published: July 2021

PurposeCurrently, in the education data use literature, there is a lack of research and examples that consider the early steps of filtering, organizing and visualizing data to inform decision-making. The purpose of this study is to describe how school leaders and researchers visualized and jointly made sense of data from a common learning management system (LMS) used by students across multiple schools and grades in a charter management organization operating in the USA. To make sense of LMS data, researchers and practitioners formed a partnership to organize complex data sets, create data visualizations and engage in joint sensemaking around data visualizations to begin to launch continuous improvement cycles.Design/methodology/approachThe authors analyzed LMS data forn= 476 students in Algebra I using hierarchical cluster analysis heatmaps. The authors also engaged in a qualitative case study that examined the ways in which school leaders made sense of the data visualization to inform improvement efforts.FindingsThe outcome of this study is a framework for informing evidence-based improvement cycles using large, complex data sets. Central to moving through the various steps in the proposed framework are collaborations between researchers and practitioners who each bring expertise that is necessary for organizing, filtering and visualizing data from digital learning environments and administrative data systems.Originality/valueThe authors propose an integrated cycle of data use in schools that builds on collaborations between researchers and school leaders to inform evidence-based improvement cycles.

PurposeWaqfplayed a powerful Islamic social finance instrument throughout Islamic history. However, the popularity ofwaqfdeclined in recent years. It is essential to understand the past research, the research gaps and thewaqf’s ignorant research areas within the existing literature to enhance thewaqfsystem. Therefore, this study aims to carry a detailed analysis ofwaqfresearch development with a careful evaluation of the scientific panorama’s different aspects inherent in Islamic business and social finance.Design/methodology/approachScientometrics is a discipline that studies the quantitative characteristics and characteristics of science and technological research, technology and innovation. This research’s string includeswaqfas a reference in the “Article title, Abstract and Keywords” based on Scopus from 1990 to 2020. The analysis was conducted in December 2020. The Bibliometrix R Package, VOSviewer and Excel’s software are used to analyse the collected data and apply the bibliometric analysis.FindingsThe findings derive thatwaqfresearch can be categorized into three sub-areas, such as the research onwaqffundamentals, analysis on cashwaqfand research on variouswaqfapplications in Islamic social finance. Even though there is some essential or fundamental research inwaqf, these are not good enough for such a powerful Islamic social finance instrument. This study finds research gaps in the existingwaqfliterature and presents nine future research directions.Originality/valueTo the best of the authors’ knowledge, this paper is the first to examinewaqf’s existing literature with bibliometric analysis. The results and the recommended possible research areas can help scholars and researchers to carry future research to enhance the scientific development of Islamic social finance and provide alternative instruments to eradicate poverty in societies.
Workplace spirituality, organizational commitment and life satisfaction: the moderating role of religious affiliation
Authors: Jeon Ki Seok , Choi Byoung Kwon 
Published: July 2021

PurposeBased on a multidimensional perspective of workplace spirituality, the authors examined a moderated mediation model, wherein workplace spirituality leads to life satisfaction through organizational commitment moderated by employees' religious affiliation.Design/methodology/approachData were collected from South Korean employees, and hypotheses were tested using hierarchical regression analysis.FindingsThree subdimensions of workplace spirituality – meaning at work, membership and inner life – were positively related to organizational commitment. In addition, organizational commitment mediated the relationships between the subdimensions and life satisfaction. Employees' religious affiliation moderated the relationship between the inner life and organizational commitment, which, in turn, also mediated the interactive effect on life satisfaction.Practical implicationsBased on the awareness of the importance of workplace spirituality, organizations need to endeavor to help employees find meaningfulness in their work, experience a climate of mutual understanding and feel a sense of trust and respect within organizations by providing opportunities or resources to fulfill their needs to spiritual self. In addition, organizations need to consider implementing policies to support employees to pursue their inner spirit not only within the workplace but also in the areas of personal life.Originality/valueThis study verifies the internal mechanisms behind the workplace spirituality – life satisfaction relationship and underlines how religious affiliation interacts with workplace spirituality to influence organizational commitment and life satisfaction.
The determinants of foreign direct investment: what about the potential of the Arab Maghreb countries?
Authors: Khalfaoui Hamdi , Derbali Abdelkader 
Published: July 2021

Purpose
The purpose of this paper is to elucidate the main determinants of foreign direct investment (FDI) in the case of the Arab Maghreb countries.

Design/methodology/approach
We employ a dynamic panel analysis using the General Method of Moments for a sample composed of 105 countries over the period 1985–2018.

Findings
We show that FDI stability, market size, higher education enrolment, quality of institutions, distance, sharing of common border, and bilateral investment and integration agreements are the main determinants of FDI location. These determinants are neither general. The potential for attracting FDI from AMU countries is poorly exploited. FDI to the AMU is lower than estimated stock. The observed FDI to potential FDI ratio does not exceed 87%. France and Spain are the main investors in the AMU region thanks to historical and cultural links. The FDI from the United States, Canada, Germany, Belgium, and Japan are below what is expected.

Originality/value
The contribution of this paper is observed on the examining oh the determinants of the FDI in the Arab Maghreb countries. Our study demonstrate that the political stability can decrease investment risk in these countries. The administrations correspondingly require expanding their rules and strategies with union demonstrations which were at the beginning of the departure and closing of several foreign companies.
Leadership-promoted diversity climate and group identification
Authors: Žnidaršič Jana , Bogilović Sabina , Černe Matej , Kumar Gupta Roopak 
Published: July 2021

PurposeBesides diversity's positive effects, groups of “we” against “them” may form in accordance with social categorization theory, showing diversity's negative consequences. The authors aim to reconcile these results and examine their boundary conditions.Design/methodology/approachThe authors studied 584 working professionals from five contexts (transnational companies dealing with multicultural interactions) and analyzed data using moderated-mediation procedures.FindingsA leader-promoting diversity climate plays a crucial role in moderating the negative relationship between perceived dissimilarity and group identification, which is mediated by value dissimilarity.Originality/valueThis study mainly contributes by treating dissimilarity as a multicomponent construct, emphasizing the crucial differences embodied in various conceptualizations of dissimilarity – namely visible and value dissimilarity. For dissimilarity to result in group identification, the results highlight leaders' crucial role, beyond that of organizations and individuals, in stimulating a diversity-embracing climate in work units.

Published: July 2021

Purpose
Workplace and study environments generally provide opportunities for social connectedness, however, not all individuals in such settings are equally well connected. It is possible that potential mental health benefits of participation in social leisure activities may be greater for individuals that lack social connectedness through a workplace or study environment. This study aims to examine if the association between social leisure activities and mental health is moderated by the degree of social connectedness at work/school.

Design/methodology/approach
Data stem from 2,406 adults (age range 16-64 years old) from The Danish Mental Health and Well-Being Survey 2016. Validated scales were used to measure mental well-being and depression/anxiety symptoms. Multivariable linear regression analyses were conducted.

Findings
Participation in social leisure activities (i.e. participation in community/social groups such as a sports association, art club, book club, running group, card game club, cultural or political group) was positively associated with mental well-being and negatively associated with depression/anxiety symptoms. The associations were stronger among individuals feeling less socially connected at work/school and strongest among individuals that were unemployed or not enrolled in education.

Originality/value
Mental health promotion strategies may focus on promoting social leisure activities especially among unemployed or otherwise socially isolated groups, as well as among individuals that are not well connected at their workplace or school. Workplaces and schools may also monitor employee/student social connectedness and potentially intervene accordingly.

Published: July 2021

PurposeThis research studies a location-allocation problem considering the m/m/m/k queue model in the blood supply chain network. This supply chain includes three levels of suppliers or donors, main blood centers (laboratories for separation, storage and distribution centers) and demand centers (hospitals and private clinics). Moreover, the proposed model is a multi-objective model including minimizing the total cost of the blood supply chain (the cost of unmet demand and inventory spoilage, the cost of transport between collection centers and the main centers of blood), minimizing the waiting time of donors in blood donating mobile centers, and minimizing the establishment of mobile centers in potential places.Design/methodology/approachSince the problem is multi-objective and NP-Hard, the heuristic algorithm NSGA-II is proposed for Pareto solutions and then the estimation of the parameters of the algorithm is described using the design of experiments. According to the review of the previous research, there are a few pieces of research in the blood supply chain in the field of design queue models and there were few works that tried to use these concepts for designing the blood supply chain networks. Also, in former research, the uncertainty in the number of donors, and also the importance of blood donors has not been considered.FindingsA novel mathematical model guided by the theory of linear programming has been proposed that can help health-care administrators in optimizing the blood supply chain networks.Originality/valueBy building upon solid literature and theory, the current study proposes a novel model for improving the supply chain of blood.
Problems of political unrest: women in small businesses in Bangladesh
Authors: Jaim Jasmine 
Published: July 2021

PurposeWhereas the extant literature on women's entrepreneurship is almost exclusively focused on developed nations, the effect of many context-specific issues of other countries on ventures of women has been overlooked. The study aims to reveal how political unrest, a common feature of the developing nation, can significantly affect the experiences of women in small businesses of that region.Design/methodology/approachThis feminist research is conducted on Bangladesh, which is one of the most politically unstable countries in the world. The study conducts interviews with women to explore the adverse effect of political unrest on their small firms.FindingsThe feminist research reveals some problems of women business-owners concerning political unrest in this highly patriarchal context. It also discloses how political chaos challenges the government initiative in financially supporting women business-owners.Practical implicationsPolicymakers of developing nations can be benefitted by taking into account the problems of women business-owners concerning political unrest, specifically the access to debt financing issues while designing policies for women's empowerment.Originality/valueThe article contributes to the women's entrepreneurship scholarship with reference to political unrest, a contextual issue of developing nations. Whereas the existing studies mostly concentrate on holding women individually liable for the limited scale of their business operation, this research potentially challenges the view by drawing upon political unrest as an external factor that negatively affects their ventures. The study further advances the prevailing knowledge by critically unveiling some gender-specific problems of women business-owners regarding political unrest.
Escaping Tree-Support (ET-Sup): minimizing contact points for tree-like support structures in additive manufacturing
Authors: Kwok Tsz-Ho 
Published: July 2021

Purpose
Support structures are often needed in additive manufacturing (AM) to print overhangs. However, they are the extra materials that must be removed afterwards. When the supports have many contacts to the model or are even enclosed inside some concavities, removing them is very challenging and has a risk of damaging the part. Therefore, the purpose of this paper is to develop a new type of tree-support, named Escaping Tree-Support (ET-Sup), which tries to build all the supports onto the build plate to minimize the number of contact points.

Design/methodology/approach
The methodology is to first classify the support points into three categories: clear, obstructed and enclosed. A clear point has nothing between it and the build plate; an obstructed point is not clear, but there exists a path for it to reach the build plate; and an enclosed point has no way to reach the build plate. With this classification, the path for the obstructed points to come clear can be found through linking them to the clear points. All the operations are performed efficiently with the help of a ray representation.

Findings
The method is tested on different overhang features, including a lattice ball and a mushroom shape with a concave cap. All the supports generated for the examples can find their way to the build plate, which looks like they are escaping from the model. The computation time is around one second for these cases.

Originality/value
This is the first time truly realizing this “escaping” property in the generation of tree-like support structures. With this ET-Sup, it is expected that the AM industries can reduce the manufacturing lead time and save much labor work in post-processing.
