Abstract
Purpose
The purpose of this study is to analyze the thermo-diffusion process in a semi-infinite nonlocal fiber-reinforced double porous thermoelastic diffusive material with voids (FRDPTDMWV) in light of the fractional-order Lord–Shulman thermo-elasto-diffusion (LSTED) model. By virtue of Eringen’s nonlocal elasticity theory, the governing equations for the considered material are developed. The free surface of the substrate is governed by the inclined mechanical load and thermal and chemical shocks.
Design/methodology/approach
With the aid of the normal mode technique, the solutions of the nondimensional coupled governing equations have been obtained.
Findings
The expressions of field variables are obtained analytically. By using MATHEMATICA software, various graphical implementations are presented to describe the impacts of angle of inclination, fractional-order and nonlocality parameters. The present model is also validated on the basis of some comparative studies with some preestablished cases.
Originality/value
As observed from the literature survey, many different studies have been carried out by taking into account the deformation analysis in nonlocal double porous thermoelastic material structures and thermo-mechanical interaction in fiber-reinforced medium under fractional-order thermoelasticity theories. However, to the best of the authors’ knowledge, no research emphasizing the thermo-elasto-diffusive interactions in a nonlocal FRDPTDMWV has been carried out. Moreover, the effect of fractional-order LSTED theory on fiber-reinforced thermoelastic diffusive half-space with double porosity has not been illuminated till now, which significantly defines the novelty of the conducted research.

Learning outcomes
This case study intends to help learners understand the concept of segmentation, targeting and positioning (STP) in the case of services. The idea of services is different from that of a product as in services; intangible elements dominate the value creation. By exploring the practical scenarios faced by the protagonist, in this case, readers would enhance their problem-solving abilities in similar situations.
Case overview/synopsis
Prerna is the founder of Ecoplore, an aggregator cum booking platform for eco-hotels. It onboards hotels only if they are made up of vernacular architecture and maintains at least 33% of greenery on its premises. Listed properties also harvested rainwater, used renewable source of energy, used sustainable options instead of single use plastic, composted organic waste. Most of these properties grow vegetables, fruits and herbs, and the visitors enjoy homemade organic meals. Ecoplore is the only aggregator platform to visit and verify these eco-hotels directly. Ecoplore is an early-stage startup; all customer queries were handled by Prerna, on-call or through a chat box. It included interacting with prospective clients, understanding their requirements, suggesting the most suited options and booking the eco-hotels. Prerna had to spend most of the time interacting with clients. Over time, she comprehended that only a few prospective clients became Ecoplore’s customers, and the conversion rate was low of owing to various reasons like ticket size, clients' age and psychology.
Complexity academic level
For students: This case is aptly designed for marketing students pursuing Bachelor’s in Business Administration and Master of Business Administration courses to understand and apply STP theory and service marketing concepts.

Abstract
Purpose
Effects of corrosion are very dire and mitigation of corrosion holds prime importance. Protective coatings play major role in preventing corrosion of metals and coating application is the most convenient, economical and quick solution. The purpose of the study is development of protective coatings to effectively mitigate corrosion of metal components.
Design/methodology/approach
A high-performance anticorrosion coating was prepared using multiple monomers and paste of functional and reinforcing fillers with extenders to protect metal components from corrosion in aggressive environmental conditions. The structures of copolymers synthesized with multiple monomers were studied by the NMR and FT-IR spectroscopic techniques. The percentage conversion of different proportions of various monomers was estimated using gas chromatography technique. The functional paste to impart superior anticorrosion properties was prepared using various functional and reinforcing fillers. The final coatings were prepared by mixing these resins with functional paste in various proportions.
Findings
The prepared anticorrosion coating was tested for high-performance mechanical and chemical properties and it was witnessed that the said coating offered desired performance properties needed for protecting metal components from corrosion.
Research limitations/implications
As such it is overcoming drawbacks of two pack systems and thus has almost no limitations or implications for application on metal substrate.
Practical implications
Being formulated as a single pack, it is free from drawbacks otherwise involved in two pack system of conventional paints. The coating system developed is very easy to apply using conventional tools, namely, brush, spray and roller techniques. The formulation is made in such a way that it has fast-drying properties. Makes painting or coating operations cost effective and confirm the performance.
Social implications
The findings of the research have anticorrosion nature that can enhance the life span of the substrates. It is specially designed for metal substrate and can protect metal substrate from corrosion in most aggressive conditions. Thus, it helps to reduce losses due corrosion and increase safety of metal structures and human being as well. As it is based on conventional material but with new formulation and technology, it has commercial possibilities to explore.
Originality/value
Unlike conventional protective coating systems, the said coating offered disruptive features like single pack systems and fast drying at ambient temperature along with high-performance properties. The coating formulation was observed to have a great importance in industry for effective corrosion mitigation and to reduce losses due to corrosion.

Abstract
Purpose
Using social exchange and power-dependence theories, this study advances the emergent debate on the dark side of leadership by examining the impact of despotic leadership style on employees’ supervisor-rated job performance, job satisfaction and turnover intention with individual-level power distance orientation as a moderator.
Design/methodology/approach
We collected multisource and time-lagged survey data in two waves from 65 leaders and 300 subordinates as paired responses working in different banks, telecom and IT companies.
Findings
It was found that employees’ exposure to despotic leadership harms their job performance and job satisfaction and has a positive effect on their turnover intention. In line with our prediction, low power distance orientation employees react more strongly to despotic leadership while high power distance orientation mitigates its effects on employee job outcomes.
Practical implications
Despotic behavioral tendencies must be taken into consideration while selecting and appointing leaders. Organizational leaders should also refrain from opportunistic and exploitative use of their followers' efforts.
Originality/value
This study adds to the emerging literature on the dark side of leadership by examining the relationship of despotic leadership style with employee job outcomes. The unique contribution of this study is the examination of individual-level power distance orientation as the boundary condition of these relationships.

Abstract
Purpose
This study examines the effect of three negative behaviors namely alienation behavior, cynicism behavior and silence behavior on employees’ intention to leave work in the telecommunication sector in the Sultanate of Oman.
Design/methodology/approach
Using a simple random sampling technique, data was collected using a questionnaire from 204 employees working in two leading telecommunication service providing agencies (Omantel and Ooredoo) in Oman. The collected data was analyzed using structural equation modeling (SEM) through AMOS software.
Findings
The findings of the study indicate a significant effect of both cynicism behavior and work alienation behavior on employees’ intention to leave work while silence behavior did not appear to affect employees’ intention to leave work.
Practical implications
The research suggests that the policymakers are required to take corrective measures and implement policies and work practices that ensure employees’ sincere engagement to work.
Originality/value
The findings contribute to the knowledge regarding the effect of employees’ negative behavior on the intention to leave work. The work is novel in the context of studying the effect in the Sultanate of Oman.

Abstract
Purpose
The practice of cronyism is a pervasive problem for most businesses and a great hindrance for employees, but empirical literature on its outcomes is scant. In light of such gaps, the objective of this study is to examine the relationship between organizational cronyism and employees' silence behavior through the mediating role of felt violation and the moderating role of continuance commitment.
Design/methodology/approach
A time-lagged cross-sectional survey comprising 226 respondents is carried out in a metropolitan city of a developing country (Lahore, Pakistan). The respondents were selected using the convenience sampling technique.
Findings
The findings reveal that organizational cronyism influences employees' silence (acquiescent and quiescent) both directly and indirectly (via felt violation). However, continuance commitment was noted to work as a boundary condition only between felt violation and quiescent silence.
Research limitations/implications
Although the study deals with common method bias by collecting data in two waves, it may restrict causality. The findings not only have implications for the academicians, but also contribute to the conservation of resources theory. This study suggests organizations develop and implement a comprehensive intervention strategy that focuses on both prevention and damage control as a result of organizational cronyism.
Originality/value
Drawing upon the conservation of resources theory, this study adds value to the literature by empirically investigating the outcomes of cronyism at work. Moreover, the outcomes and mechanisms under consideration have largely been ignored in the literature.

Abstract
Purpose
The purpose of this paper is to study epoxy and parylene C‐coated samples. These coatings are used to protect the electronic devices from harsh environments. The effect of these conformal coatings on electronics reliability is considered.
Design/methodology/approach
Epoxy coating is applied using dip coating and parylene C is applied with the vapour deposition polymerisation method. Test chip used is joined using flip‐chip technology and an anisotropically conductive adhesive. Reliability of the test samples is evaluated in a constant humidity test, where test conditions are 85°C and 85%RH. The test lasts 4,000 h. Failure analysis is carried out by cross‐sectioning failed samples and using scanning electron microscopy for closer analysis.
Findings
The results show variation in the reliability of adhesive joints with different conformal coating materials. Failure analysis highlights explicit failure mechanisms. Adhesion testing is also carried out on the test samples after constant humidity testing. The results of these reliability tests indicate clearly that parylene C is a more reliable choice of conformal coating than epoxy.
Originality/value
The paper shows the influence of certain conformal coatings on the reliability of adhesive flip‐chip joints. In medical applications, reliability plays an important role.

Abstract
Purpose
Remote work has allowed IT professionals to engage in “side hustles”, which is against the law in the Indian labour market. Professionals in the IT industry are constantly being scrutinized due to the emerging “side hustling” culture, and as a result, they are frequently subjected to rude and uncivil behaviour by others. This study aims to examine the outcome of workplace incivility on the employee’s job search behaviour and their silence. Along with this, it examines the intervening effect of organizational cynicism on the interrelation of workplace incivility with job search behaviour and employee silence. It further investigates the buffering role of workplace friendship in the link between workplace incivility and organizational cynicism.
Design/methodology/approach
In this study, a mixed-methods approach was used, which included testing the structural model followed by a qualitative study. In Study 1, the structural model testing of time-lagged primary data from 252 respondents who worked in information technology (IT) or information technology-enabled services was done, whereas Study 2 included a qualitative analysis.
Findings
The findings disclose that workplace incivility is positively connected to job search behaviour and employee silence. Organizational cynicism significantly intervenes in the link between workplace incivility and job search behaviour, and between workplace incivility and employee silence, whereas workplace friendship functions as a moderator in the link between workplace incivility and organizational cynicism. The findings indicate that if an employee experiences incivility at work, then workplace friendship plays an active role in encouraging the cynical behaviour of targeted employees towards their organisation.
Originality/value
In the past, investigators have investigated the concept of workplace incivility; however, to the best of the authors’ knowledge, its impact on job search behaviour is studied for the first time ever, whereas its impact on employee silence is studied for the first time in a moonlighting context in Indian industry. In light of the massive layoffs in India's IT industry because of employees' pursuit of side hustles, the results of this study will help firms better comprehend the negative repercussions of workplace incivility. These effects include employees' reluctance to speak up about problems at work and an increase in their frequency of actively seeking other employment.

Abstract
While there has been increasing interest in the impact of courtmandated education finance reform on school district efficiency, research on the subject is scant. Taking advantage of New Jersey Supreme Court cases that have altered the way in which state school aid is distributed, this paper examines the effect of changes in the education finance system on school district efficiency. Building on existing literature on public sector efficiency, a longitudinal data analysis based on two-stage DEA models reveals that courtmandated increases in state aid to a limited number of poor school districts decreased the districts' efficiency. Though these results should be interpreted with some caution, in particular, the limitation of DEA as an efficiency measure, they imply that, as with any policy, policy makers and courts should be aware of how policy changes affect local government behavior and that it is necessary to evaluate policy outcome taking into account both resources and performance.
