Public food procurement for Italian schools: results from analytical and content analyses
Authors: Salvatore Fiorella Pia , Fanelli Simone , Lanza Gianluca , Milone Michele 
Published: May 2021

PurposeThe study objective was to understand if uniformity of approach exists in evaluation methods of public food tender for schools at national and local level. This purpose was divided into three sub-objectives: (1) to extract the main criteria, (2) to document the synthesizing findings process and (3) to prioritize the different decision-making alternatives through pairwise comparisons.Design/methodology/approachTo achieve the sub-objectives (1) and (2), a content analysis of the Italian food tenders was carried out. Analytic hierarchy process was used to evaluate and compare the importance of various food tender evaluation criteria (3). The inclusion criteria were: cities' selection; metro area population; population density; duration of the contract; years.FindingsSix public food tenders were analyzed. The first one concerned the National legislation guidelines. The remaining five food tenders were categorized according to the city investigated. Four macro-categories (Food quality; Sustainability; Resources; Ancillary services) were classified. AHP revealed that “Food quality” and “Resources” categories have greater importance in the evaluation phase of almost all cities investigated.Originality/valueThis study in-depth analyzes each criterion used to evaluate public food tenders, providing a new methodological framework for assigning scores to clusters of criteria. Since the literature search did not reveal any previous study on a quantitative evaluation of elements such as short supply chain, organic food and environmental impacts on public food tenders, this research delivers interesting results and fills this knowledge gap.
The link between independent directors and firm’s performance: the moderating role of corporate social responsibility
Authors: Tran Hien Thi 
Published: May 2021

PurposeThis paper aims to examine how independent directors (IDs) affect a firm’s performance measured on profitability, with corporate social responsibility (CSR) interaction.Design/methodology/approachThe study uses an international data set of 1,817 firm-year observations from 545 large companies in 20 countries across Asia, America and Europe, and the fixed-effects estimation method.FindingsThe direct effect of IDs alone on profitability is statistically insignificant; however, the synergic effect of IDs and CSR on profitability becomes significantly positive when firms disclose CSR information.Practical implicationsThe profitability is partially sourced from the synergy of IDs and stakeholders through CSR. IDs may use CSR disclosure to win stakeholders’ goodwill. This goodwill will likely be transformed into profitability. The empirical results indicate that there should be more need for IDs’ engagement in CSR projects as the resources of IDs combined with external stakeholders can be of important value to firms.Originality/valueThis paper reveals the underlying mechanism that firm-idiosyncratic value is formed using a combination of ID resources and stakeholders through CSR. This research extends the literature of IDs’ efficiency and effectiveness and confirms the agency theory and resource dependence theory.
Effect of transverse and parallel magnetic fields on thermal and thermo-hydraulic performances of ferro-nanofluid flow in trapezoidal microchannel heat sink
Authors: Sepehrnia Mojtaba , Khorasanizadeh Hossein , Shafii Mohammad Behshad 
Published: May 2021

Purpose
This paper aims to study the thermal and thermo-hydraulic performances of ferro-nanofluid flow in a three-dimensional trapezoidal microchannel heat sink (TMCHS) under uniform heat flux and magnetic fields.

Design/methodology/approach
To investigate the effect of direction of Lorentz force the magnetic field has been applied: transversely in the x direction (Case I);transversely in the y direction (Case II); and parallel in the z direction (Case III). The three-dimensional governing equations with the associated boundary conditions for ferro-nanofluid flow and heat transfer have been solved by using an element-based finite volume method. The coupled algorithm has been used to solve the velocity and pressure fields. The convergence is reached when the accuracy of solutions attains 10–6 for the continuity and momentum equations and 10–9 for the energy equation.

Findings
According to thermal indicators the Case III has the best performance, but according to performance evaluation criterion (PEC) the Case II is the best. The simulation results show by increasing the Hartmann number from 0 to 12, there is an increase for PEC between 845.01% and 2997.39%, for thermal resistance between 155.91% and 262.35% and ratio of the maximum electronic chip temperature difference to heat flux between 155.16% and 289.59%. Also, the best thermo-hydraulic performance occurs at Hartmann number of 12, pressure drop of 10 kPa and volume fraction of 2%.

Research limitations/implications
The embedded electronic chip on the base plate generates heat flux of 60 kW/m2. Simulations have been performed for ferro-nanofluid with volume fractions of 1%, 2% and 3%, pressure drops of 10, 20 and 30 kPa and Hartmann numbers of 0, 3, 6, 9 and 12.

Practical implications
The authors obtained interesting results, which can be used as a design tool for magnetohydrodynamics micro pumps, microelectronic devices, micro heat exchanger and micro scale cooling systems.

Originality/value
Review of the literature indicated that there has been no study on the effects of magnetic field on thermal and thermo-hydraulic performances of ferro-nanofluid flow in a TMCHS, so far. In this three dimensional study, flow of ferro-nanofluid through a trapezoidal heat sink with five trapezoidal microchannels has been considered. In all of previous studies, in which the effect of magnetic field has been investigated, the magnetic field has been applied only in one direction. So as another innovation of the present research, the effect of applying magnetic field direction (transverse and parallel) on thermo-hydraulic behavior of TMCHS is investigated.
Sharing economy research in hospitality and tourism: a critical review using bibliometric analysis, content analysis and a quantitative systematic literature review
Authors: Mody Makarand Amrish , Hanks Lydia , Cheng Mingming 
Published: May 2021

Purpose
This study aims to conduct a critical review of the research on the sharing economy to identify its key intellectual foundations and their evolution and offers thematic and methodological recommendations for future research to advance the domain.

Design/methodology/approach
A tri-method approach using bibliometric (co-citation) analysis, thematic content analysis and a quantitative systematic literature review was conducted on sharing economy research in hospitality and tourism journals, up to and including May 2020.

Findings
The findings from the three methods were coherent and provide a clear picture of the fact that while research on the sharing economy in hospitality and tourism has achieved significant depth, the breadth of the understanding of this area remains somewhat limited. Each of the three periods of research on the sharing economy identified in the study were marked by a focus on specific thematic areas, with largely Western-situated researchers demonstrating limited theoretical engagement and using a limited range of methods and perspectives (disciplinary, stakeholders and sectors) to examine these themes.

Research limitations/implications
Recommendations for future thematic research opportunities are provided using a multi-level perspective. The present review does not include research that incorporates the impacts of COVID-19, which has significantly disrupted the hospitality and tourism industry and is the focus of current research in the field. However, the review represents the largest and most comprehensive assessment of the state of research on the sharing economy prior to COVID-19, and, as such, can serve as a valuable baseline for future reviews of sharing economy research during and after the pandemic.

Originality/value
In contrast with previous literature reviews, the present review is comprehensive in its scope, methodology and temporal coverage of sharing economy research. It also examines the evolution of research on the topic, enabling a more nuanced identification of gaps and future thematic and methodological research opportunities.

Authors: Aditya Bayu Rima , Ferdiana Ridi , Kusumawardani Sri Suning 
Published: May 2021

Purpose
This study aims to test a theoretical framework to identify and prioritize barriers in the implementation of digital transformation in higher education.

Design/methodology/approach
The framework was tested using the context of a particular nation: Indonesia. First, a survey questionnaire was conducted to identify the key barriers. Second, the contextual relationship between the key barriers was determined based on an expert’s input to find the importance level of barriers and the degree of difficulty to fix the barriers. Finally, a barrier priority matrix was developed to prioritize the barriers.

Findings
This study identified the key barriers in the implementation of digital transformation in higher education in Indonesia including eight contextual issues, one technical issue and two cultural issues with different levels of importance and difficulty. Based on the matrix constructed, this study also presented a list of the top 11 priorities of barriers.

Research limitations/implications
The results were based on a particular region context.

Practical implications
This study lays the foundation for the theoretical framework that is practically useful to perform the identification and prioritization of barriers. Besides, the result discussed in this study gives some direction for policymakers in designing sensible strategies to overcome the barriers.

Originality/value
The main contribution of this study is an empirical study that systematically identifies and prioritizes barriers to digital transformation in higher education.

Authors: Mahmoud Mahmoud Abdulai , Mallen-Ntiador Tracy Nana Ebaskwa , Andoh Dominic , Iddrisu Mustapha , Kastner Adelaide Naa Amerley 
Published: May 2021

PurposeThe purpose of this study is to test consumer xenocentric tendencies on foreign goods purchase intention and to examine the mediating role of cultural openness on the relationship.Design/methodology/approachA total number of 204 respondents participated in the study. Web-based sampling technique was employed to select a cross-section of consumers. Structural equation modelling technique of AMOS 21 version was used to test the nature of relationships in the research hypotheses.FindingsThe results suggest that except country image and interpersonal influence, all other constructs had a positive significant relationship with the intention to purchase. Country of origin, self-confidence and self-esteem had impact on consumer intention to purchase foreign products, though exposure of consumers to other cultures did not endear them to the products of those foreign markets.Practical implicationsFrom a managerial perspective, management awareness of xenocentrism tendencies is the surest way to make prudent decisions with respect to stocking and distributing foreign and local products or services.Originality/valueThe current study brings newness to the phenomenon as it tests consumer xenocentric (C-XEN) constructs in an emerging economy, and cultural openness as a mediating variable.
The effect of monetary incentives on task attractiveness, effort and performance
Authors: Robinson Michael , Farkas Maia 
Published: May 2021

PurposeThere is a longstanding debate regarding the effectiveness of financial incentives in improving work performance. This study is motivated by seemingly conflicting theory and mixed research evidence, and advances the management accounting literature on pay-for-performance by examining the separate and joint effects of task attractiveness and monetary incentives on allocation of effort and on performance.Design/methodology/approachThis study uses an online, multi-period, mixed design experiment with two independent groups of participants who receive either incentive pay or flat pay to perform a multidimensional job. The job tasks differ in complexity and participants can choose how to distribute effort between tasks. Observations are taken across two periods.FindingsIf the complex task is initially viewed as attractive it becomes less attractive over time, while the attractiveness of the simple task is stable. Participants who receive flat pay and who find the complex task attractive spent more time on working on that task than those compensated with incentives. Incentives caused higher initial performance than flat pay among participants who find the complex task to be attractive, but the differential is transient; dissatisfaction with initial performance seemingly contribute to a decline in attractiveness and deterioration in performance.Research limitations/implicationsThe results indicate that task attributes and personal preferences moderate the effects of incentives on performance and that further research is needed to examine strategies to mitigate spillover effects of deficient performance to subsequent periods. However, the findings may not be applicable to extremely complex work environments involving numerous tasks and/or group work.Practical implicationsShowing that incentives may have a positive but transitory effect on performance, because task attributes and personal preferences moderate the incentive-performance relationship, may have practical implications for hiring, job design and compensation systems design.Originality/valueThis paper contributes to the literature on pay-for-performance by using a setting that better represents contemporary work environments than prior studies have and introduces choice over effort allocation. Additionally, we contribute to theory by showing that economics and psychology theories should be viewed as complements in investigating the intricate relationship between incentives and performance.
Digital transformation in financial services provision: a Nigerian perspective to the adoption of chatbot
Authors: Abdulquadri Abdulazeez , Mogaji Emmanuel , Kieu Tai Anh , Nguyen Nguyen Phong 
Published: May 2021

Purpose
Recognising the high numbers of unbanked and financially excluded adults in Nigeria, this study aims to position chatbot as a digital transformation tool to radically change business model, improve customer experience and enhance financial inclusion in emerging markets.

Design/methodology/approach
The Search-Access-Test (S-A-T) model was adopted to understand how Nigerian banks are adopting chatbots.

Findings
A majority of Nigerian banks now have chatbots that enhance customer engagement and financial inclusion. WhatsApp was the most frequently used platform. Chatbots were often branded and presented with female gender identification. The chatbots were less responsive beyond their predefined path. While Nigeria is a multilingual country with English being the original language, none of the chatbots used any of the Nigerian’s local languages.

Practical implications
Brands need to re-evaluate their chatbots with regard to responsiveness, predefined questions, verification and privacy. There are also possibilities of branding the chatbot and developing content creation strategies for proper engagement. Beyond English, the integration of African languages into chatbot is essential for digital transformation. Digital literacy and skills, particularly in the field of science, technology, engineering and mathematics, should be supported to equip future developers and create more jobs.

Originality/value
While many theoretically based models for investigating the adoption of digital technologies have often placed focus on users’ ability to engage, this study takes an alternative perspective; by using the S-A-T model, it lays the responsibilities on the banks and chatbot developer to ensure that their chatbots are secure, responsive and able to meet the needs of the customers.

Authors: Duppati Geeta , Scrimgeour Frank , Chancharat Surachai , Kijkasiwat Ploypailin 
Published: May 2021

PurposeThis paper aims to investigate how ethnic diversity and finance options impact the survival of small- and medium-sized enterprises (SMEs) in New Zealand.Design/methodology/approachThis study incorporates survey data and secondary data from the public domain. The surveys were conducted across six sectors of the economy categorised into four main ethnic groups involving six nationalities. This study adopts regression analysis using Probit, Logit and linear probability.FindingsThe financing choices of the entrepreneurs were consistent with pecking-order theory. The evidence suggests that information asymmetries are prevalent in New Zealand, as SMEs’ owners perceive significant risk from expanding businesses internationally. There is no relationship between ethnicity bias and the survival of firms.Originality/valueThis study provides a contribution to the literature on factors relating to business survival and guides the policymakers to use the benefits of potential factors to increase the survival rate of SMEs.
Uncertainty and nonlinear macroeconomic effects of fiscal policy in the US: a SEIVAR-based analysis
Authors: Belke Ansgar , Goemans Pascal 
Published: May 2021

PurposeThe purpose of this paper is to investigate whether the macroeconomic effects of government spending shocks vary with the degree of macroeconomic uncertainty.Design/methodology/approachThe authors use quarterly US data from 1960 to 2017 and employ the Self-Exciting Interacted VAR (SEIVAR) to compute nonlinear generalized impulse response functions (GIRFs) to an orthogonalized government spending shock during tranquil and in uncertain times. The parsimonious design of the SEIVAR enables us to focus on extreme deciles of the uncertainty distribution and to control for the financing side of the government budget, monetary policy, financial frictions and consumer confidence.FindingsFiscal spending has positive output effects in tranquil times, but is contractionary during times of heightened macroeconomic uncertainty. The results indicate an important role of the endogenous response of macroeconomic uncertainty. Investigating different government spending purposes, only increases in research and development expenditures reduce uncertainty and boost output during uncertain times.Originality/valueThe authors contribute to the literature in using a method which allows to control for a large set of confounding factors and accounts for the uncertainty response.
Audit committee and financial reporting quality: the moderating effect of audit quality
Authors: Mardessi Sana 
Published: May 2021

PurposeThe purpose of this study is to address the impact of audit quality on financial reporting quality proxied by real earnings management. To further clarify the mentioned links, this study empirically assesses the moderating effect of audit quality.Design/methodology/approachThe study is based on a sample consisting of 90 non-financial companies that are listed in the Amsterdam stock exchange in AEX all share index over the 2010–2017 period. This study applies a quantitative approach and secondary data as the main source of information for analysis. This paper performs an ordinary least squares regression to examine the moderating effect of audit quality on the relationship between financial reporting quality.FindingsEmpirical findings demonstrate that corporate governance mechanism, mainly independence members, financial expert and audit committee size has a statistically significant relationship with real earnings management. However, the effect of audit committee meetings on real earnings management is not significant. There is also evidence that audit quality moderates the audit committee – real earnings management links.Originality/valueThis study extends the existing literature by examining the moderating effect of audit quality on the relationship between financial reporting quality proxied by real earnings management in the Dutch context.

Coping with workplace ostracism through ability-based emotional intelligence
Authors: Ayub Arslan , Sultana Fatima , Iqbal Shahid , Abdullah Muhammad , Khan Nishwa 
Published: May 2021

PurposeWith a basis in the conservation of resource (COR) theory, this study examines the relationship between workplace ostracism and job performance while also investigating the mediating role of defensive silence and the moderating role of emotional intelligence.Design/methodology/approachThe study uses a multisource, three-wave data collection technique to gather data from employees and their peers working in Pakistan's service sector organizations. Data are analyzed using partial least squares structural equation modeling (PLS-SEM) (v 3.2.7) to assess the measurement model and the structural model.FindingsThe findings reveal that the perception of workplace ostracism provokes self-avoidance strategy, defensive silence, which attenuates job performance. However, defensive silence's mediating role is mitigated if employees can draw from their emotional intelligence ability, which induces a self-regulation mechanism that curbs workplace ostracism's negative consequences.Practical implicationsThe study demonstrates how employees in collectivist, high-power distance cultural settings may strategically choose silence by exercising emotional intelligence to enhance job performance.Originality/valueThis study is one of the few efforts that examined defensive silence in non-Western cultural settings. This is also the first study that examined emotional intelligence's role in the proposed moderated mediation framework.
