Effect of Na2SiO3 concentration on microstructure and corrosion resistance of MAO coatings prepared on Al-Mg-Sc alloys
Authors: Wu Mingjin , Jiang Feng , Jiang Jingyu 
Published: May 2022

Purpose
The purpose of this paper is to investigate the effect of Na2SiO3 concentration on the microstructure and corrosive properties of microarc oxidation (MAO) coating on Al-Mg-Sc alloy and explore microstructure evolution rule of Al substrate in the contact area.

Design/methodology/approach
The Na2SiO3 concentration in electrolytes influenced the microstructure and corrosion behavior of MAO coatings. Instantaneous high temperature and high pressure due to microarc discharge caused annealing treatment. The corrosive behavior of the MAO coating was featured with polarization curves and electrochemical impedance spectrum in 3.5 Wt.% NaCl solution.

Findings
The substrate in the contact area existed the instantaneous annealing treatment, which caused obvious recrystallization. The coating prepared in electrolyte containing 7 g/L Na2SiO3 exhibited the highest protective properties in 3.5 Wt.% NaCl solution.

Originality/value
MAO treatment could increase the corrosion resistance by producing a protective layer on the Al-Mg-Sc alloy surface at a suitable Na2SiO3 concentration and microstructure evolution rule of Al substrate in the contact area was obtained.
Territorial servitisation in Italian industrial districts: the role of technological and professional KIBS
Authors: Baldoni Edoardo , De Propris Lisa , Storai Dimitri 
Published: May 2022

Purpose
This paper aims to analyse to what extent Italian industrial districts (IDs), with their traditional manufacturing specialization, experimented a territorial servitisation process in terms of spread of specifically professional and technological knowledge-intensive business services’ activities over the period 2012–2018.

Design/methodology/approach
This paper articulates knowledge-intensive business services activities in two types, technological knowledge-intensive business services and professional knowledge-intensive business services. It tracks their growth and their co-location with manufacturing sectors in Italian IDs by means of firm employment data and location quotients. Firm employment data is extracted from Statistical Archive of Active firms (ASIA) data set provided by Italian National Institute for Statistics (ISTAT). ASIA data is matched with ISTAT territorial identification of Italian local labour systems and IDs.

Findings
In 2018, Italian IDs featured, next to their traditional over-specialisation in manufacturing activities, an under-specialisation in knowledge-intensive business services’ activities. Nevertheless, the dynamic analysis carried out over the period 2012–2018 shows that IDs firm employment in technological knowledge-intensive business services and professional knowledge-intensive business services grew at a higher rate than the national average.

Originality/value
The novelty of this paper is to distinguish between technological knowledge-intensive business services and professional knowledge-intensive business services and to measure the presence and the growth of these two different types of knowledge-intensive business services in Italian IDs.

Authors: Shah Syed Saqib , Öztop Hakan F. , Ul-Haq Rizwan , Abu-Hamdeh Nidal 
Published: May 2022

Purpose
The purpose of this paper is to analyse the buoyancy flow, mass and heat transfer in coaxial duct under Soret and Dufour effect. The combined effects of the thermal-diffusion and diffusion-thermo coefficients, as well as the Schmidt number, on natural convection in a heated lower coaxial curve were explored using the proposed physical model. The Dufour and Soret effects are taken into consideration in the energy and concentration equations, respectively.

Design/methodology/approach
The dominating mathematical models are converted into a set of non-linear coupled partial differential equations, which are solved using a numerical approach. The controlling non-linear boundary value problem is numerically solved using the penalty finite element method with Galerkin’s weighted residual scheme over the entire variety of essential parameters.

Findings
It was observed that different parameters were tested such as heat generation or absorption coefficient, buoyancy ratio, Soret coefficient, Dufour coefficient, Lewis number and Rayleigh number. Effect of Rayleigh number, absorption/generation and Dufour coefficient on isotherm are significantly reported. For greater values of Lewis number, maximum mass transfer in duct in the form of molecular particles is produced. Buoyancy ratio parameter decreases the average rate of heat flow and increases its mass transfer.

Originality/value
The main originality of this work is to make an application of Soret and Dufour effects in a coaxial duct in the presence of source sink.
Enhancing food production to prevent households from food insecurity in rural Burkina Faso: does land ownership matter?
Authors: Séogo Windinkonté 
Published: May 2022

Purpose This paper assesses the effect of land ownership on household food security through its productivity enhancement effect in rural Burkina Faso.Design/methodology/approach As the link between land tenure security and productivity is indirect, the study relies on a complex mixed process regression model with robustness to assess the effect of land ownership on household productivity. Then, an instrumental variable (IV) approach is followed to investigate the association between household productivity and food security. The rural development program survey data collected from 1,892 households in 2017 are used.Findings The complex mixed process estimation results are robust and show that land ownership has a positive effect on household productivity. From the IV results, it is found that productive households spend more on food, have a low share of expenditures on food and are less likely to experience severe food shortages, implying an improvement in their food security status. This highlights a positive association between land ownership and food security.Originality/value Unlike previous studies that only focused on the effect of land ownership on land-related investments and agricultural productivity, this study deepens the analysis and sheds light on how land ownership, agricultural production and food security are related. It gives empirical evidence on the importance of land policies in the struggle against food insecurity in agrarian economies.Peer reviewThe peer review history for this article is available at https://publons.com/publon/10.1108/IJSE-11-2021-0658.

Authors: Pandey Suchitra , Mohapatra Geetilaxmi , Arora Rahul 
Published: May 2022

PurposeThe purpose of the present study is to examine the inter-relationship between the multi-dimensional poverty and water poverty using household level data for Indian states.Design/methodology/approachA modified water poverty index (MWPI) for both rural and urban households was created using the five components approach and various quantifiable proxies. Principal component analysis (PCA) has been used for the construction of MWPI. Multidimensionality of poverty (MPI) is measured using the Alkire and Foster methodology. Further, the study has utilized correlation and Tobit regression analysis to show the relationship between MWPI and MPI.FindingsThe empirical findings suggest that there is a positive and significant relationship between multidimensional poverty and water poverty, with the extent of relationship being greater in rural areas. The results show that in rural areas all the components of water poverty has significant impact on multidimensional poverty, whereas in urban areas except use component all others have significant impact on multidimensional poverty. Further, components of multidimensional poverty were also found to be significantly impacting water poverty.Practical implicationsThe study suggests that policymakers cannot treat both forms of poverty in isolation. If India aims to reduce poverty, then it needs to pay significant attention to improving water conditions.Originality/valueThis is a pioneering attempt to construct water poverty index at the household level while accounting for micro-level differences for Indian economy. It highlights that water poverty leads to multi-dimensional poverty and vice-versa.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-12-2021-0731.
Machining of titanium alloys using phosphonium-based halogen-free ionic liquid as lubricant additives
Authors: Bambam Arun Kumar , Dhanola Anil , Gajrani Kishor Kumar 
Published: May 2022

Purpose
Nowadays, ionic liquids (ILs) are used as lubricant additives because of their ability to improve tribological characteristics. However, majority of the ILs contains halogen-based anions. They are extremely sensitive to moisture and produce detrimental halides and halogen acids when reacted with moisture and water. These halides and halogen acids are harmful to the health and environment of the operator’s. This paper aims to study four different lubricants including two halogen-based ILs blended in canola oil and two phosphonium-based halogen-free ILs blended in canola oil and in pure canola oil.

Design/methodology/approach
Viscosity and contact angle were measured by using rheometer and contact angle goniometer, respectively. Machining experiments were performed using turning centre with four different lubricants at two different cutting speeds and temperatures, and the machining forces, tool morphology and roughness of the machined surface were analysed.

Findings
The results showed that the inclusion of 1% phosphonium-based halogen-free ILs blended in canola oil increased the viscosity by 44.8% and reduced the cutting and thrust force by 21.7% and 26.8%, respectively, compared to pure canola oil lubricant. Microscopic analysis of tool showed lower adhesive and abrasive wear when machined with phosphonium-based halogen-free ILs blended in canola oil. The workpiece surface roughness reduced by 32% for phosphonium-based halogen-free ILs blended in canola oil compared with pure canola oil.

Originality/value
Halogen-free ILs are possible green lubricants, as they do not contain harmful elements such as F, S, B and Cl like halogen-based ILs. To the best of the authors’ knowledge, this is presumably the first work which shows machining performance of halogen-free ILs as lubricant additives.
Does intellectual capital efficiency improve the corporate social responsibility of Egyptian firms?
Authors: Awad Bakry Ahmed Elsayed 
Published: May 2022

PurposeCorporate social responsibility (CSR) has been one of the main subjects for companies’ sustainability in contemporary years. Engaging in CSR practices has been recognized to be beneficial for firms since it might create value for firm in the market. The process of creating value in recent era has been controlled by firms’ hidden resources and simultaneously the concept of value added intellectual capital (VAIC). This paper aims to determine whether intellectual capital (IC) and each of its three constituents (human capital efficiency [HCE], capital employed efficiency [CEE] and structural capital efficiency [SCE]) can generate improvements in CSR in an emerging market.Design/methodology/approachUsing the Egyptian Corporate Responsibility (S&P/EGX ESG) index and extracting accounting data from the annual reports of companies listed on this index, an empirical analysis that considers VAIC and its elements was accomplished on a sample of 267 firm-year observations for a nine-year period beginning in 2010.FindingsThe empirical results of the multivariate regression indicated that Egyptian companies active in using IC have more tendency to engage in CSR practices. In addition, it is shown that HCE positively influences CSR practices, while SCE has a negative association with such social activities, and CEE has no significant relationship with CSR activities.Practical implicationsThe results of the research have some implications through offering an enhanced understanding of using IC and CSR practices that might be in favor of several investors, regulatory bodies and scholars concerned with firms’ social activities. Besides, it provides empirical evidence that the efficient use of IC provides advantages not only for the stockholders but also for the community.Originality/valueTo the best of the authors’ knowledge, this study is one of the first studies to investigate Egyptian firms for IC and CSR topics. In addition, this study provides empirical evidence on this relationship from the Egyptian environment that is different from other cultural and institutional environments in which previous studies were conducted.

Authors: Li Bin , Wan Jiayu , Qi Lin , Hang Jianping 
Published: May 2022

Purpose
This paper aims to unveil the importance of knowledge management on a firm’s strategic emergency response during the great negative shock from global public health threats. Through analyzing how representative firms in China’s new economy industries dealt with the COVID-19 pandemic before, during and after the crisis, the significant problems confronted by these firms are pointed out, and the important role knowledge management capabilities played in solving these problems is proven.

Design/methodology/approach
The open data of listed companies regarding the important role knowledge management played in firms’ strategic emergency response during the COVID-19 pandemic are qualitatively analyzed. Based on theoretical sampling, this paper selects representative samples of enterprises and analyzes the positive response measures they took after being hit by this public health event to gain qualitative insight into the importance of knowledge management capabilities in strategic emergency response.

Findings
Three aspects of the important role of knowledge management capabilities in a firm’s strategic emergency response during the COVID-19 pandemic are introduced: before the crisis, firms should strengthen the acquisition, sharing and integration of knowledge so that they can intensify their monitoring for uncertain risks; during the crisis, firms should boost the transmission, transformation and diffusion of knowledge to improve emergency cooperation; and after the crisis, companies should reinforce knowledge evaluation, creation and application to enhance “immunity” in similar emergencies.

Research limitations/implications
This paper has important implications for bolstering strategic emergency management practice and knowledge management capability among firms. Future research must focus on the following two aspects for further investigation: the dynamic relationship between firm knowledge management capability and strategic emergency response ability; and the collaboration system between firm knowledge management and strategic emergency response behaviors.

Originality/value
This paper discusses the important role knowledge management capabilities play in firms’ strategic emergency responses based on insights gained from the significant changes that the COVID-19 pandemic caused to representative Chinese new economy firms. By analyzing the three stages of before, during and after the emergency, this paper proposes the exact efforts that new economy companies should make in improving knowledge management capability.

Authors: Matagi Leonsio , Baguma Peter , Baluku Martin Mabunda 
Published: May 2022

PurposeThe purpose of the study is to establish the relationship between age, job involvement, job satisfaction and job performance of sub-county chiefs in the Ugandan local government.Design/methodology/approachA cross-sectional survey design was used to obtain a total sample of 320 sub-county chiefs who were selected to participate in the study using multi-stage stratified random sampling. A self-administered questionnaire was used to collect data that were entered into the computer using Statistical Package for the Social Sciences, version 23 (IBM SPSS-AMOS). Path analysis results were used to test the hypotheses.FindingsThe results indicated significant positive relationships between: age and job involvement, job involvement and job satisfaction, and job involvement and job performance. Non-significant relationships were between age and job satisfaction, age and job performance, and job satisfaction and job performance. A reconstructed model was presented.Practical implicationsEmployees’ participation in decisions that affect their work brings positive behavioral outcomes. Job involvement makes workers feel as part of the organization and contributes significantly to organizational effectiveness and morale of workers. Managers are encouraged to pay much attention to the requirements of their staff so as to increase their job involvement, which can ultimately lead to high levels of job satisfaction and improved job performance.Originality/valueThis study proposes that older employees who highly participate in organizational activities are likely to be satisfied and outstanding performers. Strategic recruitment agencies are very important in ensuring “quality at the gate” because they focus on the work attitudes and can attract and retain a satisfied and competent workforce.
Managerial hubristic-behavioral strategy: how to cope with chaotic and uncertain contexts
Authors: Loia Francesca , de Gennaro Davide , Adinolfi Paola 
Published: May 2022

Purpose
How can a manager lead an organization or a team in a particularly turbulent time? How can management cope with chaos and uncertainty? Drawing on behavioral strategy theory, this study aims at investigating how hubristic managers can enable organizations to thrive, even over small time periods, in chaotic and uncertain contexts and settings.

Design/methodology/approach
This study uses a qualitative methodology to explore the possible positive effects of hubris in a behavioral strategy. In particular, 45 interviews with leaders and followers of particularly high-performing secondary schools have been administered to try to fully understand the origin, process and performance evolution of organizations led by hubristic managers.

Findings
The results showed that, in chaotic and uncertain times, hubris can prove to be a trump card for managers in dealing with the pitfalls and uncertainties of the context in which the organization operates. Three major attributes were identified – overconfidence and over-persistence, recklessness and contempt for critical feedback – defining the positive behavioral strategies implemented by hubristic managers during the COVID-19 pandemic.

Originality/value
To the best of the authors’ knowledge, this study is the first to highlight, by means of qualitative methodologies, the positive managerial hubristic-behavioral strategy during turbulent times in the school sector.

Published: May 2022

Purpose
Intervention strategies are designed by policymakers to impact people by effectively changing the environment in which people make decisions. Many government-led agencies and nongovernmental organizations promote behavioral change by adopting social marketing strategies. Social marketing uses the application of commercial ideas to influence the voluntary behavior of individuals. Under these circumstances, this study aims to examine the effect of these emerging brand-building techniques social marketing especially in public campaign.

Design/methodology/approach
This descriptive study collected opinions related to the constructs from 324 respondents across India. This study used statistical package for the social science and Smart partial leased square software to test the validity of the hypotheses.

Findings
The results of this study indicate that when the campaigns target the emotional state of the consumer, he or she crosses all boundaries like physical attributes, service parameter or even any form of assessment and provides incremental value to the campaign, thus forming a favorable behavior.

Research limitations/implications
This study provides insights on how emotional branding can be used for better involvement and relationship building, which leads to long-term engagement with the customers. The marketers can also get facilitated through this study by developing a new perspective of creating their advertisements through emotional branding techniques, especially with a focus on corporate social responsibility in the global environment.

Originality/value
In recent times, marketers have adopted a new communication strategy to build their brand through promotions that might appeal directly to customer’s emotional state, popularly termed as “emotional branding.” This new communication strategy aims at creating and nurturing a relationship between the consumer and the brand by accumulating memories, emotions, personal narratives and expectations.
Food web consequences of thermal asymmetries
Authors: Gibert Jean P. , Grady John M. , Dell Anthony I. 
Published: May 2022

Abstract

Understanding how food webs will respond to globally rising temperatures is a pressing issue. Temperature effects on food webs are likely underpinned by differences in the thermal sensitivity of consumers and resources, or thermal asymmetries. We identify three sources of asymmetry in the rising portion of thermal performance curves: inter‐thermy variation across thermoregulatory groups, intra‐thermy variation within a thermoregulatory group and rate‐dependent variation in how different ecological rates respond to temperature.

We use a large empirical dataset on thermal sensitivities across thermoregulatory groups to explore how prevalent thermal asymmetries are in real consumer–resource interactions. We then develop theory to illustrate how food web temperature responses are mediated by the magnitude and direction of these thermal asymmetries. We use this model to show possible conditions under which food webs could respond to warming as currently expected, and when that may not be the case.

Our results suggest that inter‐thermy, intra‐thermy and rate‐dependent asymmetries are likely common in natural food webs. We show how all thermal asymmetries have important effects on species abundances across trophic levels as well as the maximum trophic position in the food web. Both the direction of the asymmetries (i.e. which species respond more strongly) and their magnitude (the difference in thermal responses) determine the temperature response of the food web and, consistent with current expectations, top predator abundance almost always declines with temperature, even though maximum trophic position may increase.

While our model shows that food web temperature responses can be varied, much of this variation can be explained by considering thermal asymmetries. Our study provides new data and theoretical insights into the widely varying food web effects of warming observed in laboratory, experimental and observational settings, and clarifies how predator and prey thermal ecology may influence overall food web responses in a changing world.
