Abstract
Purpose
The purpose of this paper is to propose a research model in which work engagement (WENG) mediates the effects of servant leadership (SL) and authentic leadership (AL) simultaneously on career satisfaction and adaptive performance. It also aims to test whether SL better explains WENG and the aforesaid outcomes than AL.
Design/methodology/approach
This paper used time-lagged data collected from hotel employees and their direct supervisors in Turkey. Structural equation modeling was implemented to assess the aforesaid linkages.
Findings
Among others, the indirect impact of SL on career satisfaction and adaptive performance, through WENG, is stronger than the indirect effect of AL.
Practical implications
Management can use AL as a base to develop and boost SL. Appraising employees’ WENG on a periodical basis would enable management to understand whether SL really contributes to the enhancement of WENG. In addition, employees can take advantage of informal learning to foster their adaptive performance.
Originality/value
There are calls for research to ascertain whether SL better explains outcomes than other leadership styles such as AL. Evidence about the underlying mechanism linking SL and AL to outcomes is still sparse. The extant research on SL and AL has neglected adaptive performance in frontline service jobs so far. With this stated, this paper aims to fill in these voids.

Abstract
The profession of judicial advisory is a profession with a larger scope, which creates solutions for legal problems by harmoniously blending principles, theories, and standards that relate to many areas of expertise such as accounting, auditing, and law. The legists need expert information on the matters of accounting, finance, and taxation regarding the files that they handle. In such cases, experts who perform the profession of judicial advisory provide their consultancy services to the legists before and during the cases.
The purpose of this study is to create awareness regarding the profession of judicial advisory and put forward the prospects of this profession in Turkey. The study includes four provinces located in the Eastern Black Sea Region (Trabzon, Rize, Ordu, and Giresun). There are a total of 1,339 lawyers who are registered to the bar associations of the indicated provinces; out of them, 600 lawyers have been communicated, but a questionnaire was conducted on 354 lawyers by employing face-to-face interviews. The data obtained from the questionnaires have been subjected to difference in means (unpaired t-test) and descriptive statistical analyses by using the statistical packet software of SPSS 10.0.
In the consequence of the conducted analyses, it has been determined that the lawyers thought that the members of the profession of accounting working as experts were inadequate. In the event of establishing judicial advisory institution besides the institution of expertise, it is believed that a more beneficial system would be created. It is seen that this thought has not changed among the lawyers in terms of different characteristics except level of education. Additionally, it has been determined that the level of awareness of the lawyers regarding the profession of judicial advisory was insufficient.

Abstract
Purpose
The purpose of this paper is to propose a novel lean management tool to provide a comprehensive and flexible evaluation model while converting customer voices into technical characteristics in lean implementations.
Design/methodology/approach
For this purpose, the proposed model was constructed by belief space-evaluations, quality function deployment (QFD) and analytic hierarchy process (AHP) in interval type-2 fuzzy (IT2F) environment. This model involves three phases: determining the linguistic weights and belief-based relations with their IT2F-sets, processing information about IT2F-based belief-evaluations and ranking the technical characteristics using the defuzzified belief-based relative importance values.
Findings
The proposed model was applied to automotive after-sales service in Turkey to demonstrate its use in lean service-decisions. This model was compared with its classical and type-1 fuzzy versions. The ranking-results of the proposed model differed from those of the other versions. The reason is that the IT2F-environment offers a sensitive and flexible evaluation of the model’s linguistic scales.
Research limitations/implications
Calculations in the proposed model may be quite involved for practitioners. An Excel-dashboard was created to simplify the computational complexity.
Practical implications
Researchers/practitioners can apply this model to any lean manufacturing/service implementation.
Social implications
Company managers/employees/customers can recognize their perception-mechanisms via belief space-evaluations and experience how uncertainty in the perception-mechanism affects their decisions.
Originality/value
The proposed model provides a new lean tool due to the Bayesian model combined with QFD-AHP in IT2F-environment. This model eliminates the ambiguity in conceptual change-based lean decisions.

Abstract
Purpose
The purpose of this study is to introduce a new numerical scheme with no stability condition and high-order accuracy for the solution of two-dimensional coupled groundwater flow and transport simulation problems with regular and irregular geometries and compare the results with widely acceptable programs such as Modular Three-Dimensional Finite-Difference Ground-Water Flow Model (MODFLOW) and Modular Three-Dimensional Multispecies Transport Model (MT3DMS).
Design/methodology/approach
The newly proposed numerical scheme is based on the method of lines (MOL) approach and uses high-order approximations both in space and time. Quintic B-spline (QBS) functions are used in space to transform partial differential equations, representing the relevant physical phenomena in the system of ordinary differential equations. Then this system is solved with the DOPRI5 algorithm that requires no stability condition. The obtained results are compared with the results of the MODFLOW and MT3DMS programs to verify the accuracy of the proposed scheme.
Findings
The results indicate that the proposed numerical scheme can successfully simulate the two-dimensional coupled groundwater flow and transport problems with complex geometry and parameter structures. All the results are in good agreement with the reference solutions.
Originality/value
To the best of the authors' knowledge, the QBS-DOPRI5 method is used for the first time for solving two-dimensional coupled groundwater flow and transport problems with complex geometries and can be extended to high-dimensional problems. In the future, considering the success of the proposed numerical scheme, it can be used successfully for the identification of groundwater contaminant source characteristics.

Abstract
This chapter explains the role and potential of colour and lighting as two important elements of the service atmosphere in tourism and hospitality service encounters. The chapter first explains the importance of colour and lighting in services from the perspective of customers’ sensory perceptions. Then, the chapter provides examples to demonstrate how psychological/neuro-marketing tools of Eye Tracker and Facial Recognition, Galvanic Skin Response (GSR) and Heart Rate (HR) can be used to understand the role of colour and lighting in customer satisfaction in tourism and hospitality service encounters. Based on this perspective, the study offers recommendations to design service environments in terms of colour and lighting.

Abstract
Purpose
The purpose of this study is to determine the effects of the psychosocial work environment on the turnover of civil service cadre officers in rural areas in Bangladesh.
Design/methodology/approach
Physical intimidation, mental health and well-being, organisational impediments, decision latitude, psychological job demands and social interaction were developed as variables to examine in relation to job satisfaction and turnover. This study gathers 406 responses from Bangladesh Civil Service (BCS) cadre officers in rural areas to test the hypotheses.
Findings
The findings indicate that physical intimidation increases employee turnover, whereas psychosocial job demand decreases it. Physical intimidation reduces job satisfaction, whereas decision flexibility and social interaction enhance job satisfaction, hence reducing the turnover of civil service cadre officers in rural Bangladesh.
Originality/value
This research contributes to the creation of context-specific and targeted public sector support, particularly the interventions and policies addressing the work environment in rural areas.

Abstract
Purpose
This study aims to investigate the effects of entrepreneurial leadership on service innovation in the hospitality industry and examine the mediating effects of market-sensing capability and knowledge acquisition. Additionally, the study explores the moderating role of competitive intensity in the relationships between market-sensing capability, knowledge acquisition and service innovation, drawing on the dynamic capability theory and resource dependence theory.
Design/methodology/approach
The data for this study were obtained from 322 employees and 137 leaders working in 103 hotels in Vietnam, using a time-lagged approach. The collected data were analyzed using structural equation modeling in SPSS Amos 28.
Findings
The results of this study reveal a significant positive association between entrepreneurial leadership and service innovation, with mediation effects observed through both knowledge acquisition and market-sensing capability. Moreover, the findings demonstrate that competitive intensity moderates the association between knowledge acquisition and service innovation.
Practical implications
The results of this study provide implications for hospitality firms to cultivate entrepreneurial leadership through leadership training and development programs and enhance their dynamic capabilities (i.e. market-sensing capability and knowledge acquisition) to allow them to survive and develop in a competitive market.
Originality/value
This study advances entrepreneurial leadership research in the hospitality context by identifying mediating and moderating mechanisms that translate entrepreneurial leadership into hospitality firms’ service innovation.

Abstract
Purpose
The purpose of this paper is to apply an efficient semi-analytical method for the approximate solution of Lienard’s equation of fractional order.
Design/methodology/approach
A Laplace decomposition method (LDM) is implemented for the nonlinear fractional Lienard’s equation that is complemented with initial conditions. The nonlinear term is decomposed and then a recursive algorithm is constructed for the determination of the proposed infinite series solution.
Findings
A number of examples are tested to explicate the efficiency of the proposed technique. The results confirm that this approach is convergent and highly accurate by using only few iterations of the proposed scheme.
Originality/value
The approach is original and is of value because it is the first time that this approach is used successfully to tackle fractional differential equations, which are of great interest for authors in the recent years.

Abstract
Purpose
There are many studies investigating people’s eating habits during the COVID-19 period, and people have been encouraged to eat healthier. Healthy nutrition is made possible by making healthy food choices and food labels are one of the tools that help consumers make healthy food choices. Therefore, the primary aim of this study was to evaluate the impact of the COVID-19 pandemic on consumers’ food label reading behaviours and their level of trust in food labels.
Design/methodology/approach
This cross-sectional study was conducted on 1,012 adults aged 18–65 years from seven different regions of Turkey. Participants’ food label reading behaviours and their trust in food label information were assessed using an online questionnaire, and COVID-19 fear scores were determined using the fear of COVID-19 scale (FCV-19S).
Findings
Although not statistically significant, participants’ rate of reading food labels increased during the pandemic (65.6% vs 68.7%, p = 0.078). On the contrary, trust in label information decreased significantly (52.1% vs 43.9%, p < 0.001). In addition, increased COVID-19 fear was associated with an increased rate of food label reading and decreased trust in the label information (p < 0.001).
Research limitations/implications
Because of the study’s cross-sectional nature, the authors cannot provide a causal link between COVID-19 fear and food label reading behaviours and trust in food label information. However, it is difficult to investigate this causal link due to difficulties in studies of consumer behaviour and food choice (e.g. multifactorial effects and complexity). Second, because the present study’s findings were based on self-report data, there may be a risk of resource bias. Nevertheless, the authors think that this study will shed light on future studies as it is the first time that the COVID-19 pandemic has investigated consumers’ food label reading habits and their trust in food labels.
Practical implications
Considering the pandemic as an opportunity to change consumer behaviour, it may be useful to provide food label reading education to consumers, especially during this period. In addition, the information given on the label should be clear and understandable for a better understanding of the food label information. Furthermore, it may be beneficial to conduct food inspections more frequently and share the results with the public to increase consumers’ trust in food labels. Moreover, as the food system shifts towards a “new normal”, it is critical for policymakers to understand the changes in consumer perceptions, preferences and trust in foods.
Originality/value
COVID-19 fear affected consumers’ food label reading behaviours. As far as the authors know, there is no study about the effects of COVID-19 on consumers’ food label reading behaviours.
