Food attitudes and consumer behavior towards food in conflict-affected zones during the COVID-19 pandemic: case of the Palestinian territories
Authors: Ben Hassen Tarek , El Bilali Hamid , Allahyari Mohammad Sadegh , Morrar Rabeh 
Published: December 2021

PurposeGlobal lockdowns and restrictions linked to the coronavirus disease 2019 (COVID-19) pandemic have affected food environments and consumption patterns. Conflict-affected countries are disproportionately affected from economic and food security perspectives. In this regard, the Palestinian territories (namely West Bank and Gaza Strip), which face a number of issues such as Israeli military and economic control, overcrowded cities and refugee camps (especially in Gaza Strip), rising poverty and food insecurity, are an especially interesting case study. Accordingly, the purpose of this paper is to analyze the effects of the ongoing COVID-19 pandemic on the selection and intake of foods and drinks, as well as consumer behavior and attitude toward food in the Palestinian territories.Design/methodology/approachThe paper draws upon an online survey in the Palestinian territories administered in Arabic through the Survey Monkey platform from September 15 to October 10, 2020, with 322 adults. The survey findings were analyzed using descriptive statistics and several nonparametric tests. Particularly, the U-Mann Whitney test was used in dichotomous, categorical independent variables (e.g. gender), while the Kruskal–Wallis test was run to analyze multi-choice responses (e.g. occupation).FindingsThe results reveal that food attitudes and consumer behavior towards food have been widely affected. First, they reveal that Palestinians try to have healthier diets but ate more between meals (e.g. snacks). Second, the pandemic transformed respondents' shopping behavior and induced panic buying, negatively affecting food affordability due to increased prices of some foods (e.g. fruits and vegetables). Some food behaviors were shaped by negative psychological determinants (e.g. depression and anxiety). The pandemic effects are moderated by different sociodemographics (age, education and income). COVID-19 negatively affected food security but also opened a “window of opportunity” to trigger the transition towards more sustainable diets.Originality/valueThe paper results show that the eventual effects of COVID-19 will most likely vary from country to country, based not only on the epidemiological circumstances but also, among other factors, on the baseline socioeconomic situation and shock resilience. The findings contribute to the clarification and critical analysis of the impacts of COVID-19 on food behaviors in the Palestinian territories, which would have several policy implications.
Analysing drivers of efficiency in the leather industry: a two-stage double bootstrap DEA approach
Authors: Singh Aparajita , Gundimeda Haripriya 
Published: December 2021

PurposeThe Indian leather industry contributes to economic growth at a significant environmental cost. Due to the rising global demand for sustainable leather products, promoting efficient input utilisation has become vital. This study measures input efficiency and its determinants for leather industry in order for it to improve its future performance.Design/methodology/approachIn the first stage, bootstrap data envelopment analysis (DEA) approach is used for measuring efficiency and analysing firms' differences based on their geographical location, organisational structures, urban-rural location and sub-industrial groups. A second stage regression examines efficiency determinants using size, age, skill and capital-labour intensity as the explanatory variables.FindingsEfficiency result shows a significant potential of minimising inputs by 47% provided the firms adopt best practices. West Bengal firms, urban located firms, individual and proprietorship owned firms and leather consumer goods firms are found to be relatively efficient to their counterparts. Size, skilled managerial staff and labour-intensive firms positively affect efficiency.Practical implicationsConstruction of well-connected roads for accessing urban retail markets and provision of reliable electricity would improve efficiency of rural firms. Small-scale enterprises have a larger share in Indian leather industry; therefore, policy should focus on enhancing the firms' scale and investing in training facilities to skill employed labour for ensuring optimal use of inputs.Originality/valuePrevious studies on the leather industry have used the conventional DEA efficiency measurement approach. This study uses DEA bootstrapping model for robust efficiency estimates and provides consistent inferences about the determinants.

Authors: Hazim Kaoutar , Parent Guillaume , Duchesne Stéphane , Nicolet Andrè , Geuzaine Christophe 
Published: December 2021

Purpose
This paper aims to model a three-dimensional twisted geometry of a twisted pair studied in an electrostatic approximation using only two-dimensional (2D) finite elements.

Design/methodology/approach
The proposed method is based on the reformulation of the weak formulation of the electrostatics problem to deal with twisted geometries only in 2D.

Findings
The method is based on a change of coordinates and enables a faster computational time as well as a high accuracy.

Originality/value
The effectiveness of the adopted approach is demonstrated by studying different configurations related to the IEC 60851-5 standard defined for the measurement of the electrical properties of the insulation of the winding wires used in electrical machines.
Modeling anisotropic magnetic hysteresis properties with vector stop model by using finite element method
Authors: Xiao Xiao , Müller Fabian , Nell Martin Marco , Hameyer Kay 
Published: December 2021

Purpose
This paper aims to use a history-dependent vector stop hysteresis model incorporated into a two dimensional finite elements (FE) simulation environment to solve the magnetic field problems in electrical machines. The vector stop hysteresis model is valid for representing the anisotropic magnetization characteristics of electrical steel sheets. Comparisons of the simulated results with measurements show that the model is well appropriate for the simulation of electrical machines with alternating, rotating and harmonic magnetic flux densities.

Design/methodology/approach
The anisotropy of the permeability of an electrical steel sheet can be represented by integrating anhysteretic surfaces into the elastic element of a vector hysteresis stop model. The parameters of the vector stop hysteresis model were identified by minimizing the errors between the simulated results and measurements. In this paper, a damped Newton method is applied to solve the nonlinear problem, which ensures a robust convergence of the finite elements simulation with vector stop hysteresis model.

Findings
Analyzing the measurements of the electrical steel sheets sample obtained from a rotational single sheet tester shows the importance to consider the anisotropic and saturation behavior of the material. Comparing the calculated and measured data corroborates the hypothesis that the presented energy-based vector stop hysteresis model is able to represent these magnetic properties appropriately. To ensure a unique way of hysteresis loops during finite elements simulation, the memory of the vector stop hysteresis model from last time step is kept unchanged during the Newton iterations.

Originality/value
The results of this work demonstrates that the presented vector hysteresis stop model allows simulation of vector hysteresis effects of electrical steel sheets in electrical machines with a limited amount of measurements. The essential properties of the electrical steel sheets, such as phase shifts, the anisotropy of magnetizations and the magnetization characteristics by alternating, rotating, harmonic magnetization types, can be accurately represented.

Authors: Kerem Alper , Yazgan Abdusselam 
Published: December 2021

PurposeThe purpose of this study is to monitor the surface cooling of the photovoltaic (PV) panel and the effect of the dust accumulated on the panel surface on the electrical efficiency remotely and instantaneously.Design/methodology/approachAn autonomous system has been designed that can measure and record the PV surface temperature, the amount of dust on the surface, current, voltage and power values at certain intervals. It can also perform surface cooling and cleaning with water cycle when the temperature and dust amount reach certain threshold values and transmit these values to the user via global system for mobile communications module, Bluetooth module and graphically with a touchscreen liquid crystal display panel. Thus, it is aimed to benefit from PV at the maximum level, and it was installed in Kahramanmaras Sütçü Imam University Faculty of Engineering and Architecture.FindingsAn increase in power was observed for PV surface cooling and surface dust removal by 3.78% and 45.99%, respectively.Originality/valueThis system is of vital importance in terms of time and energy-saving, especially for solar plants far from the city center, which are difficult to access because of climatic conditions. In other hand for future studies, it is foreseen that more efficiency gains can be achieved by using artificial intelligence and image processing techniques.
How to develop higher education curricula towards employability? A multi-stakeholder approach
Authors: Olo Daniela , Correia Leonida , Rego Conceição 
Published: December 2021

PurposeThis paper aims to find out what conditions are needed to enhance higher education curricula towards employability from the perspective of different stakeholders in the graduate labour market.Design/methodology/approachAn empirical study was developed, using a qualitative approach, based on semi-structured interviews with higher education institutions (HEIs) and labour market players, in the north region of Portugal. The data were analysed through content and descrip\tive analysis with NVivo.FindingsThe results show a set of constraints that hinder the match of higher education curricula with employability, namely, (1) the weak connection between HEIs and employers and (2) the curricular structure, which is characterised by a heavy theoretical component and a weak approach to the soft skills required by the current labour market. Possible solutions, with implications for educational policy, are given throughout the study.Research limitations/implicationsThe geographical scope and the nature of the study suggest that some precautions are required when generalising results. However, the literature on other areas in Portugal strengthens the findings and compensates for the sample's limitations.Originality/valueThis study combines the perspectives of the different individual stakeholders involved which, when taken as a whole, provide some recommendations for tailored curricula towards employability. Other studies in Portugal address each of these issues individually, without a connection between all the different perspectives.

Authors: Orser Barbara Jayne , Elliott Catherine Jane 
Published: December 2021

PurposeThis study aims to problematize how gender is enacted within entrepreneurship education and training (EET).Design/methodology/approachUsing a social feminist lens, this study advances principles, a conceptual framework, assessment criteria and illustrative performance metrics to inform gender-sensitive EET programs and courses. Findings are based on a cross-case thematic analysis of two large-scale case studies conducted in Canada and Jordan.FindingsThe findings bridge social feminist theory and EET studies. The originality of the research rests in its utilization of the principles and conceptual framework to examine EET and to inform the development, design and assessment of gender-sensitive programs and courses.Research limitations/implicationsThe framework and criteria do not differentiate types or levels of EET. The investigators lead the assessment of curricula and co-construction of gender-sensitive course content. Interpreter bias cannot be ruled out.Practical implicationsThe proposed principles, framework, criteria and performance will assist stakeholders in EET program/course design, content, delivery and evaluation.Social implicationsAligned with the United Nation Sustain Development Goal 5 (gender equity), the findings demonstrate the value of adapting a critical lens across all elements of EET and responding to biases in participant selection and engagement, program design and curricula.Originality/valueTo the best of the authors’ knowledge, this is among the first studies to use a social feminist perspective and case study methodology to inform criteria to assess EET.
Government size and economic growth in African emerging economies: does the BARS curve exist?
Authors: Zungu Lindokuhle Talent , Greyling Lorraine 
Published: December 2021

PurposeThis study is aimed at testing the validity of the BARS theory and determining the threshold level at which excessive government expenditure hampers growth. The data from 10 African emerging economies from 1988 to 2019 were used.Design/methodology/approachThe methodology comprises several different stages. In the first stage, an Lagrange Multiplier (LM) type test was employed to find the appropriate transition variable among all the candidate variables to assess the linearity between government expenditure and economic growth and to find the sequence for selecting the ordermof the transition function. The linearity test helped to identify the nature of the relationships between government expenditure and economic growth. In the second stage, the model evaluation was tested using the wild cluster bootstrap-Lagrange Multiplier (WCL-LM) test to assess appropriateness of the model. Thirdly, the Panel smooth transition regression (PSTR) model with one regime was estimated to test the validity of the BARS curve.FindingsThe results revealed evidence of nonlinear effects between government expenditure and economic growth, where the size of the government spending was found to be a 27.84% share of GDP, above which government expenditure caused growth to decline in African emerging economies. The findings combined into an inverted U-shape relationship, in line with the BARS theory.Originality/valueThis study proposes that policy-makers ought to formulate prudent fiscal policies that encourage expenditure, which would improve growth for selected countries as their current level of spending is below the threshold. This might be done through: (1) a suitable investment portfolio and (2) spending more on infrastructure.

Authors: Kumar Pushp , Sahu Naresh Chandra , Ansari Mohd Arshad , Kumar Siddharth 
Published: December 2021

PurposeThe paper investigates the effects of climate change along with ecological and carbon footprint on rice crop production in India during 1982–2016.Design/methodology/approachThe autoregressive distributed lag (ARDL), canonical cointegration regression (CCR) and fully modified ordinary least square (FMOLS) models are used in the paper.FindingsA long-run relationship is found between climate change and rice production in India. Results report that ecological footprint and carbon footprint spur long-term rice production. While rainfall boosts rice crop productivity in the short term, it has a negative long-term impact. Further, the findings of ARDL models are validated by other cointegration models, i.e., the FMOLS and CCR models.Research limitations/implicationsThis study provides insights into the role of ecological footprint and carbon footprint along with climate variables in relation to rice production.Originality/valueIn the literature, the effects of ecological and carbon footprint on rice production are missing. Therefore, this is the first study to empirically examine the impact of climate change along with ecological footprint and carbon footprint on rice production in India.
Corporate entrepreneurship at the university: the influence of managerial support, autonomy and reward on the innovative behavior of university professors
Authors: Moraes Gustavo Hermínio Salati Marcondes de , Spers Eduardo Eugênio , Mendes Luciano , Silva Hermes Moretti Ribeiro da 
Published: December 2021

Purpose
The study aims to analyze the influence of managerial support, autonomy and reward perception on the innovative behavior of university professors.

Design/methodology/approach
Quantitative methodology based on partial least squares structural equation modeling. The sample obtained totaled 208 responses from professors at three public universities in the State of Sao Paulo, Brazil.

Findings
The results indicate that managerial support is a fundamental factor for developing an organizational environment that is more conducive to innovative behavior and corporate entrepreneurship. However, in educational institutions with a more focused entrepreneurial ecosystem, it was discovered that reward perception is not a fundamental factor for the innovative behavior of university professors.

Practical implications
From a practical perspective, academic institutions interested in stimulating corporate entrepreneurship should create opportunities for collaboration among professors to solve problems, encourage professors to expose their work beyond the university environment and improve the main indicators of management support and autonomy presented in this research.

Social implications
The study presents indicators and implications, which are of particular interest for university managers and public policy writers.

Originality/value
The study is demonstrably original. Through its unique analysis of the innovative behavior of university professors and the connections between variables in the university environment and its use of a robust modeling method in an emerging-economy context, the study furthers existing research by helping to understand why some firms are better than others at corporate entrepreneurship.
Assessment of the quality of the service perceived in specific contexts of management of a family business
Authors: Igreja Carla Martins , Sousa Bruno Barbosa , Silva Tiago , Veloso Cláudia Miranda 
Published: December 2021

PurposeThe aim of this paper is to apply the SERVQUAL model to evaluate the quality perceived by customers in the context of family hotel management in Portugal. More specifically, to assess the influence of interpersonal relationships (service providers and customers) in family business services in the wine tourism segment (i.e. wine hotel and spa). In this way, it aims to provide data that can support this family hotel to reinforce the quality of the services provided to guests and therefore their satisfaction and loyalty.Design/methodology/approachThe statistical techniques, using Microsoft Excel 2016® and SPSS Statistics 25.0®, were multivariate for the analysis and validation of the results. In this analysis it can be seen that except the empathy dimension, in which the evaluation of perceived quality is positive, i.e. customer perceptions were higher than expectations, the remaining dimensions of the SERVQUAL model were negative. The safety dimension ranked second, followed by service delivery dimensions, problem solving and tangibility.FindingsThe results show that the empathy dimension positively influences the evaluation of the perceived quality and thus also the satisfaction and loyalty of guests to the family hotel in the wine tourism segment. So, it is recommended that the hotel management of this family hotel reinforces service quality by investing in the improvement of physical facilities, problem-solving capacity, and service delivery, to obtain higher levels of perceived quality service and hence customer satisfaction and loyalty and, simultaneously, increase its performance and organizational sustainability.Research limitations/implicationsIn addition to the direct contributions to the hotel management of this family business hotel, this study contributes to the development of the marketing scientific area, tourism and hospitality industry.Practical implicationsSeveral studies argue that the competitive advantage of the hotel business is based on the creation of value and of experiences for the customer, but in the context of family hotels, the creation of value for the customer is even more relevant, given the characteristics of this type of business, such as its small size and the reduced number of employees. Family hotels should invest in tools and techniques that allow them to create value for the customer through the quality of service offered to their guests.Originality/valueThis paper aimed to evaluate perceived quality in the context of family hotel management in Portugal. In particular, the contribution of interpersonal relationships (between service providers and guests), in hotel services in the wine tourism segment in Portugal. According to the analysis of the results of the exploratory study to Hotel context, it was concluded that there are differences between the perceptions and expectations of hotel guests.

Authors: Ramesh Rofia , Ananthram Subramaniam , Vijayalakshmi V. , Sharma Piyush 
Published: December 2021

PurposeThis paper aims to highlight the positive and negative effects of technostressors on employee attitudes using psychological need satisfaction as an explanatory mechanism and mindfulness as an individual resource, thereby developing an integrative conceptual model.Design/methodology/approachA narrative literature review was performed in the technostress, job demands-resources and mindfulness literature to develop the propositions of the integrative conceptual model.FindingsThis paper posits psychological need satisfaction as a mediator in the process by which technostressors impact important employee outcomes. It also proposes mindfulness as a personal resource that helps alleviate technostressor induced burnout and foster work engagement.Research limitations/implicationsThe proposed integrative conceptual framework provides some useful directions for future empirical research on this topic of growing importance.Practical implicationsBased on the findings of this paper, managers can devise and implement a technostressor-specific mitigation strategy to cope with information and communication technology–induced work demands. They can also introduce mindfulness-based programs to support positive outcomes when technostressors are present.Originality/valueThis paper is the first to theoretically delineate specific characteristics of technostressors as challenge and hindrance demands and makes interdisciplinary contributions by extending the role of psychological mechanisms such as psychological need satisfaction and personal resources such as mindfulness in work-related technology use research.
