An artificial compressibility method for axisymmetric swirling flows
Authors: Leloudas Stavros N. , Lygidakis Georgios N. , Delis Argiris I. , Nikolos Ioannis K. 
Published: June 2021

PurposeThis study aims to feature the application of the artificial compressibility method (ACM) for the numerical prediction of two-dimensional (2D) axisymmetric swirling flows.Design/methodology/approachThe respective academic numerical solver, named IGal2D, is based on the axisymmetric Reynolds-averaged Navier–Stokes (RANS) equations, arranged in a pseudo-Cartesian form, enhanced by the addition of the circumferential momentum equation. Discretization of spatial derivative terms within the governing equations is performed via unstructured 2D grid layouts, with a node-centered finite-volume scheme. For the evaluation of inviscid fluxes, the upwind Roe’s approximate Riemann solver is applied, coupled with a higher-order accurate spatial reconstruction, whereas an element-based approach is used for the calculation of gradients required for the viscous ones. Time integration is succeeded through a second-order accurate four-stage Runge-Kutta method, adopting additionally a local time-stepping technique. Further acceleration, in terms of computational time, is achieved by using an agglomeration multigrid scheme, incorporating the full approximation scheme in a V-cycle process, within an efficient edge-based data structure.FindingsA detailed validation of the proposed numerical methodology is performed by encountering both inviscid and viscous (laminar and turbulent) swirling flows with axial symmetry. IGal2D is compared against the commercial software ANSYS fluent – by using appropriate metrics and characteristic flow quantities – but also against experimental measurements, confirming the proposed methodology’s potential to predict such flows in terms of accuracy.Originality/valueThis study provides a robust methodology for the accurate prediction of swirling flows by combining the axisymmetric RANS equations with ACM. In addition, a detailed description of the convective flux Jacobian is provided, filling a respective gap in research literature.

Authors: Liyanaarachchi Gajendra , Deshpande Sameer , Weaven Scott 
Published: June 2021

PurposeThis paper advocates for banks to understand customers' online privacy concerns, use those insights to segment consumers and design tailored sales strategies to build a mutual relationship through a social exchange that produces a competitive advantage.Design/methodology/approachA qualitative study involving 30 in-depth interviews with Australian and Asian millennials residing in Australia was conducted using a grounded theory approach to explore privacy concerns of online banking and determine the efficacy of their banks' existing sales strategy and practice.FindingsThe study revealed differences in customer perceptions of trust, confidence, responsibility and exchange. Adopting a power-dependency paradigm within a social exchange theoretical framework and power distance belief of national culture theory, the authors identified four consumer segments: exemplar, empiric, elevator and exponent. The authors propose a tailored consumer-centered sales strategy of communication, control, consolidation and collaboration.Originality/valueThe paper contributes to the research in services marketing, sales strategy and banking in three ways: first, the authors demonstrate the importance of the social exchange theory and national culture as a premise to develop a competitive advantage; second, the authors propose an innovative set of consumer segments in regards to online privacy concerns; and, third, the authors introduce four sales strategies tailored to each of the four segments.
Empowering Islamic boarding schools by applying the humane entrepreneurship approach: the case of Indonesia
Authors: Anggadwita Grisna , Dana Leo-Paul , Ramadani Veland , Ramadan Reza Yanuar 
Published: June 2021

PurposeIslamic boarding schools are education institutions that have been developing in Indonesia as places for the Indonesian people to learn and gain knowledge in the perspectives of the Islamic religion and Indonesian nationalism. This study aims to explore the potential of Islamic boarding schools as places to support and to empower the economy and to increase the participation of students in entrepreneurial activities by applying the Humane Entrepreneurship approach. This study identifies the humane entrepreneurship approach by analyzing the humane cycle and the enterprise cycle in the entrepreneurship activities occurring in a single case study of an Islamic boarding school.Design/methodology/approachThis article used a qualitative method with a case study approach through deep exploration and observation. In-depth semi-structured interviews were conducted with the key people in one of the Islamic boarding schools in Indonesia using a purposive sampling technique. Miles and Huberman (1984) technique was used for data analysis by grouping similar text segments into codes and categorizing them for further analysis.FindingsThe findings of this study indicate that the Islamic boarding school has implemented humane entrepreneurship through entrepreneurial-oriented activities as the main aspects of the humane cycle and the enterprise cycle. The implementation of humane entrepreneurship aims to achieve entrepreneurial growth, innovation and independence of the Islamic boarding school, as well as the development of the stakeholder's capabilities, knowledge and commitment. In addition, applying the spiritual approach, which is one of the important components of Islamic boarding schools, has proven to be effective in implementing humane entrepreneurship.Research limitations/implicationsThis study has several limitations. First, this study only focused on one Islamic boarding school in Indonesia. Second, there is still very little research in the field of humane entrepreneurship, so the concept itself is still considered to be relatively new. Therefore, further direction is needed for future research regarding the exploration and identification of any other factors that might influence humane entrepreneurship.Originality/valueThis study provides new insights on the implementation of humane entrepreneurship in Islamic boarding schools. This research covers the gap where the humane entrepreneurial approach can be applied not only in large organizations, but also in religious educational institutions. The spiritual approach and religious values as the principles of Islamic boarding schools have been proven to be effective in implementing humane entrepreneurship.
Does it pay to act feminine? A cross-cultural study of gender stereotype endorsement and cognitive legitimacy in the evaluation of new ventures
Authors: Javadian Golshan , Figueroa-Armijos Maria , Gupta Vishal K. , Modarresi Meisam , Dobratz Crystal 
Published: June 2021

PurposeDoes gender stereotype endorsement play a role in the customer's cognitive evaluation of new ventures owned by women entrepreneurs? The authors’ cross-cultural study integrates literature on gender stereotype endorsement and cognitive legitimacy to address this research question.Design/methodology/approachThe authors use a two-study experimental design and analyze our results by cultural context to test our hypotheses: one drawn from college students in Iran and one from working professionals in the United States.FindingsThe authors’ comparative results suggest that the evaluation of feminine versus masculine characteristics of women entrepreneurs varies depending on the evaluator's (in this case the customer's) endorsement of gender stereotypes and the cultural context. Specifically, the authors found that a new venture owned by a woman entrepreneur who displays feminine characteristics is perceived as more legitimate when the customer endorses feminine stereotypes, regardless of the country.Research limitations/implicationsThe authors’ research contributes to the literature on cognitive legitimacy and women's entrepreneurship by unveiling the cultural conditions and factors that allow women entrepreneurs to benefit from acting in a stereotypically feminine way. The authors use a binary approach to gender. Future research should extend our findings to also include a non-binary approach.Originality/valueThis study contributes to women's entrepreneurship research by unraveling the implications of gender stereotype endorsement, legitimacy and culture in customer evaluation of ventures owned by women.
Innovation and the performance of informal enterprises in developing countries: a gender perspective
Authors: Avenyo Elvis Korku , Kraemer-Mbula Erika 
Published: June 2021

PurposeExamining the impact of gender on various aspects of business performance has gained research and policy traction, although the empirical evidence remains inconclusive. This paper aims to focus on one type of business, namely, informal enterprises and one dimension of business performance, namely, product innovation, to better understand how product innovations affect employment in both female- and male-owned informal enterprises.Design/methodology/approachThis paper relies on a unique data set of 513 informal enterprises located in two urban centres in Ghana (Accra and Tema), covering the period between 2013 and 2015 and the Dose-Response Model to examine the effect of product innovations on employment in informal enterprises in urban Ghana.FindingsThe findings suggest that product innovation has considerable beneficial impacts on the creation of employment in informal enterprises. The results do not show systematic differences in the factors affecting product innovation in female- and male-owned enterprises. However, they suggest that although female-owned enterprises are less likely to introduce product innovations, they do sell more innovative products.Originality/valueThese findings support the view that innovation is “gendered”, and therefore, requires a “gendered” policy lens.
The moderating role of life satisfaction in the relationship between burnout and depression among nursing staff: a human rights concern in Pakistan
Authors: Aslam Naeem , Khan Araib , Habib Nida , Ahmed Ammar 
Published: June 2021

Purpose
This study aims to see the role of life satisfaction in the relationship between burnout and depression among nurses to highlight the human rights norms for institutions, as well as practitioners within the health sector to improve life satisfaction among nurses.

Design/methodology/approach
This was a survey-based study. Data was collected by using well-established questionnaires. The sample (N = 250) comprising nurses taken from different public and private hospitals of Islamabad. Participants were both male (n = 125) and female nurses (n = 125), with age range 20–51 (M = 29.95, SD = 4.95) years. The data was collected by using the convenient sampling technique from different government and private hospitals of Islamabad from September 2017 to December 2017.

Findings
Bivariate correlation analysis revealed that burnout was positively associated with depression and negatively associated with life satisfaction. Moreover, depression was negatively associated with life satisfaction. Moderation analysis demonstrated that life satisfaction moderated the relationship between burnout and depression. Female nurses scored high on burnout as compared to male nurses.

Research limitations/implications
The use of self-report measures and the cross-sectional nature of the study design are the limitations of the study. The findings contribute by recognizing the various factors affecting the performance of nursing staff specifically in developing countries such as Pakistan.

Practical implications
This study demonstrated the vital implication of factors reducing depression among nursing staff through life satisfaction. Health care organizations should take measures to condense the level of burnout, make and boost a caring and fair working atmosphere to improve the level of life satisfaction, and therefore, reduce the negative emotions associated with burnout. It is concluded that life satisfaction may buffer the effect of burnout and subsequent depression.

Originality/value
This study has extended the prevailing literature by recognizing the moderating role of life satisfaction in the relationship between burnout and depression among nursing staff specifically highlighting their human rights in the Pakistani context.
If crime is not the problem, crime fighting is no solution: policing gang violence in the age of abolition
Authors: Van Hellemont Elke , Densley James 
Published: June 2021

PurposeIn their 1999 classic,Crime is Not the Problem, Zimring and Hawkins changed the way criminologists thought about crime and violence simply by forcing us to distinguish between them. In so doing, they advanced an agenda for a more effective response to the real “crime” problem in America – violence. In this short commentary, the authors apply this logic to gang research and responses. The authors argue police fall short in responding to “gangs” because researchers and policymakers have defined them in terms of criminal behaviour writ large, not the problem that really needs policing – the precise social and spatial dynamics of gang violence. The purpose of this paper is to stand on the shoulders of others who have stated violence trumps gangs when it comes to policy and practice and provide a conceptual review of the literature that captures mainstream and critical perspectives on gangs and offers both sides some common ground to start from as they contemplate “policing” gangs with or without police.Design/methodology/approachA review of the extant literature.FindingsThe authors stand on the shoulders of others who have stated violence trumps gangs when it comes to policy and practice, to provide a conceptual review of the literature that captures mainstream and critical perspectives on gangs, in North American and European contexts, and offers both sides some common ground to start from as they contemplate “policing” gangs with or without police.Originality/valueThe paper is a conceptual piece looking at policing gang violence versus gang crime. The paper aims to restart the debate around the role of crime in gangs and gangs in crime. This debate centres around whether gangs should be understood as primarily criminal groups, whether “the gang” is to blame for the crime and violence of its members and what feature of collective crime and violence designate “gangness”. We use that debate to reflect past and current police practices towards gangs.
Building a climate of faculty trust in students through principal support of student psychological needs
Authors: Adams Curt , Adigun Olajumoke Beulah 
Published: June 2021

PurposeThis study was designed to test the relationship between principal support of student psychological needs and faculty trust in students. Without direct empirical evidence to draw from, the line of reasoning integrated evidence on social-cognitive processes involved in trust formation and conversation theory to advance two hypotheses: (1) After accounting for school and leadership conditions, principal support of student psychological needs will be related to school differences in faculty trust in students; (2) The relationship between principal support of student psychological needs and faculty trust in students is mediated by a positive view of the teaching task.Design/methodology/approachHypotheses were tested with a nonexperimental, correlational research design using ex post facto data. Due to the hierarchical structure of the data, hypotheses were tested with a 2-2-1 multilevel mediation model in HLM 7.03 with restricted maximum likelihood estimation.FindingsFindings were consistent with the hypothesized relationships – principal support of student psychological needs was related to faculty trust in students and this relationship was mediated by teacher perceptions of the teaching task.Originality/valueSchool research has primarily examined interpersonal antecedents of trust, focusing on behaviors and characteristics that position a person or group as trustworthy. This study extends trust research to the cognitive side of the formation process, calling attention to the function of mental representation in shaping trust discernments. Results suggest that cognitive processes hold promise as both a source of faculty trust in students and as a malleable mental structure that school leaders can shape through conversation.
How novice analysts understand supply chain process models: an experimental study of using diagrams and texts
Authors: Leukel Joerg , Sugumaran Vijayan 
Published: June 2021

PurposeProcess models specific to the supply chain domain are an important tool for the analysis of interorganizational interfaces and requirements of information technology (IT) systems supporting supply chain decision-making. The purpose of this study is to examine the effectiveness of supply chain process models for novice analysts in conveying domain semantics compared to alternative textual representations.Design/methodology/approachA laboratory experiment with graduate students as proxies for novice analysts was conducted. Participants were randomly assigned to either the diagram group, which worked with “thread diagrams” created from the modeling grammar “Supply Chain Operation Reference (SCOR) model”, or the text group, which worked with semantically equivalent textual representations. Domain understanding was measured using cognitively demanding information acquisition for two different domains.FindingsDiagram users were more accurate in identifying product-related information and organizing this information in a graph compared to those using the textual representation. The authors found considerable improvements in domain understanding, and using the diagrams was perceived as easy as using the texts.Originality/valueThe study's findings are unique in providing empirical evidence for supply chain process models being an effective representation for novice analysts. Such evidence is lacking in prior research because of the evaluation methods used, which are limited to scenario, case study and informed argument. This study adds the diagram user's perspective to that literature and provides a rigorous empirical evaluation by contrasting diagrammatic and textual representations.
The impact of long-term riskless asset on ensuring liquidity and preventing banking fragility
Authors: Shahin Mahmoud 
Published: June 2021

PurposeThrough portfolio diversification, the author identifies the risk sharing deposit contract in a three-period model that maximizes the ex ante expected utility of depositors.Design/methodology/approachIn this paper, the author extends the study by Allen and Gale (1998) by adding a long-term riskless investment opportunity to the original portfolio of a short-term liquid asset and a long-term risky illiquid asset.FindingsUnlike Allen and Gale, there are no information-based bank runs in equilibrium. In addition, the model can improve consumers' welfare over the Allen and Gale model. The author also shows that the bank will choose to liquidate the cheaper investments, in terms of the gain-loss ratios for the two types of existing long-term assets, when there is liquidity shortage in some cases. Such a policy reduces the liquidation cost and enables the bank to meet the outstanding liability to depositors without large liquidation losses.Originality/valueThe author believe that the reader would be interested in this article because it is relevant to real world where depositors rush to withdraw their deposits from a bank if there is negative information about future prospect of the bank asset portfolio and bank investment. Economists and financial analysts need to determine the suitable mechanism to improve the stability of the bank and the depositor welfare.
The impact of consumers’ attitudes towards technology on the acceptance of hotel technology-based innovation
Authors: Cheng Vincent Ting Pong , Guo Renyu 
Published: June 2021

Purpose
Technology-based innovation (TBI) is a primary approach across the hospitality industry to improve customer experience. It is essential to know the critical factors that affect consumers’ acceptance of hotels’ TBI. The effect of consumers’ attitudes toward technology is hypothesized to affect the acceptance of TBI besides commonly used technology acceptance models.

Design/methodology/approach
A model of attitudes toward technology influence on TBI was constructed and tested by inviting participants to watch a video of a keyless check-in process of a leading hotel chain and then completed a questionnaire. The attitudes toward technology were measured using the technology adoption propensity (TAP) scale.

Findings
Attitudes toward technology strongly affect the hotel’s booking intention (BI) used as a proxy for consumers’ acceptance of hotels’ TBI. However, attitudes toward technology can only influence BI through the mediating variables of trust and curiosity.

Practical implications
The findings provide useful insights, encouraging hotels to positively enhance consumers’ attitudes toward technology when introducing TBI services.

Originality/value
Most research on the acceptance of e-commerce technology focuses on consumers’ resulting attitudes or emotions using the products or services. In contrast, this study investigates the effect of consumers’ attitudes toward technology on accepting hotels’ TBI service. The study demonstrated that attitudes toward technology substantially impact the acceptance of hotels’ TBI service. Furthermore, the study provides empirical support on the use of the TAP scale in complex TBI services.
Organizational structure and convergent change: explanatory factors in SMEs
Authors: Marín-Idárraga Diego Armando , Hurtado González José Manuel 
Published: June 2021

PurposeBy integrating the structural contingency and the organizational adaptation theories, this study analyzes the impact of the main variables of organizational structure on convergent change. The authors also examine whether some contingency variables, such as the firm's size, age and sector, may help to explain differences in the relationship between organizational structure and convergent change.Design/methodology/approachThis work was carried out through an explanatory and cross-sectional study. The hypotheses were tested through a multiple regression analysis.FindingsThis paper demonstrates that, in Bogota's SMEs, modifications in differentiation and formalization explain convergent change, and that centralization does not affect it. Furthermore, the authors find that the company's size explains these relationships, and that age and sector do not influence them.Practical implicationsThe authors provide useful information in this work to guide managers and professionals on the implications of organizational structure and convergent change, more specifically on decisions regarding hierarchical arrangement, job division and processes redefinition.Originality/valueThis work provides empirical evidence with original data for a better understanding of the reality of Colombian SMEs in the Latin American context.
