Abstract
Purpose
The purpose of this paper is to evaluate the effect of post process combinations, e.g. hot isostatic pressing (HIP) only, HIP + T6 heat treatments, and T6 only, with different aging time, on surface properties, microstructure and mechanical properties of stress-relieved AlSi10Mg parts produced by direct laser metal sintering.
Design/methodology/approach
HIP process and HIP + T6 heat treatments were applied to as stress-relieved direct laser metal sintered (DMLS) AlSi10Mg parts. Aging times of 4 and 12 h are selected to examine the optimum duration. To analyze the advantages of HIP process, a T6 heat treatment with 4 h of aging was also applied. Densities, open porosities and roughness values of as stress-relieved, HIPed, HIP + T6, and T6-only samples were measured. The samples were characterized by OM and SEM together with EDX analysis. An image analysis study was made to evaluate the inner pore structure, thereby to understand the mechanical behavior.
Findings
HIP process does not cause a significant change in surface porosity; yet it has a positive influence on inner porosity. HIP process results in a microstructure of the aluminum matrix surrounded by a network of micron and nano size Si particles. Additional heat treatment results in larger particles and precipitation. After HIPing, ductility increases but strength decreases. Samples aged 4 h present improved yield and tensile strength but decreased elongation, yet samples aged for 12 h reach a combination of optimum strength and ductility. The lower level of tensile strength and ductility in T6-only condition indicates that HIP process plays a crucial role in elimination of the porosity thus improves the effectiveness of subsequent heat treatment.
Originality/value
The study investigates the effect of post-process conditions and optimizes the aging time of the T6 heat treatment after HIP process in order to obtain improved mechanical properties. The stress-relieved state was chosen as the reference to prevent distortion during HIPing or heat treatment.

Abstract
Purpose
It is understood that the personality traits and intelligence levels of the tourist guides directly or indirectly affect their ability to solve the problems they encounter on tours. This study aims to test whether emotional intelligence has an intermediary effect on the problem-solving skills of professional tourist guides with perfectionist personality traits.
Design/methodology/approach
Field research was conducted within the study to analyze suggestions on the interaction of variables on an empirical basis, and data were collected using interview, document review and survey technique. Thus, the mixed-methods approach was used in the study. Within the scope of this study in which 410 professional tourist guides were surveyed, a substantial part of the research data was obtained through the application of the survey technique. Besides, interviews were carried out with 12 professional tourist guides. The clues obtained by the qualitative study were transformed into hypotheses within the scope of the quantitative study, and the intermediary effect was tested.
Findings
A relationship between the main themes, sub-themes and codes was determined within the framework of the qualitative method. As a result of the mediation test, it has been revealed that emotional intelligence has an intermediary role in the relationship between perfectionism and problem-solving skills. According to the results of bootstrapping, the indirect effect of emotional intelligence on perfectionism and problem-solving skills was found out to be significant.
Practical implications
The study acknowledged that positive perfectionism, high emotional intelligence and problem-solving skills contributed to the professional tourist guides being willing to provide better service. In tune with the assumption that the more the quality of the tours carried out through agencies increases, the more satisfied tourists are; the study implicated that it would be advisable for agencies to prioritize the trainings provided for their tour guides to enhance their positive perfectionist, emotionally intelligent personalities and problem-solving skills. Given that professional tourist guides may create a positive country image with the quality service they provide, the significance of such trainings stretch beyond the benefits of such organizations.
Originality/value
Relevant variables were analyzed with a mixed method and applied on professional tourist guides.

Abstract
Purpose
The main purpose of the study is to determine the mediating role of trait anxiety in the relationship between hotel managers’ perceptions of digital competence in the Cappadocia Region and their perceptions of job insecurity.
Design/methodology/approach
In this study, which is based on quantitative research, a cross-sectional design was used. The seven-item digital competence scale, four-item job insecurity scale and 20-item trait anxiety scale were used to measure the level of digital competence, job insecurity and trait anxiety of hotel managers. The convenience sampling method was used in the research, and 337 questionnaires were completed by senior and junior managers who agreed to participate in the research. To test the mediating role of trait anxiety, Andrew F. Hayes’ views on the contemporary approach were taken as a basis.
Findings
The analysis results showed that digital competence had the opposite effect on job insecurity. Similarly, digital competence had the opposite effect on the level of trait anxiety. The level of trait anxiety affected the perception of job insecurity in a linear direction. As a result of the bootstrapping test, it was found that the indirect effect of trait anxiety on the relationship between digital competence and job insecurity was significant.
Research limitations/implications
The study was unable to collect data from hotels that were closed during the COVID-19 pandemic due to restrictions. Therefore, one of the limitations of the study was that it did not reach the entire population. Another limitation of the study was that the questionnaires were addressed to hotel managers in the Cappadocia Region.
Practical implications
Hotel managers’ digital skills are considered to contribute to the tourism industry by organizing and determining business strategies, work processes and employee skills. In addition, when hiring hotel managers, it is essential to ensure that they have certain skills such as compatibility with the digital age, openness to innovation and the ability to adapt the employees working in their team to the age, which helps to improve the competitiveness of the hotel industry with the world and ensure the continuity of this situation.
Originality/value
The research addressed the variables of digital competence, job insecurity and trait anxiety and collected data from hotel managers in the Cappadocia Region using a survey technique. There were few studies that addressed these variables, and the mediating effect of trait anxiety was revealed based on the contemporary approach.

Abstract
Purpose
This study aims to identify the “should have” and “must have” capabilities required to boost a supply chain’s robustness and operational performance. Research on supply chain capabilities and their impact has long been central to the supply chain discipline. However, empirical studies continue to report mixed results regarding the relationship between integration and performance or agility and robustness. Using a novel methodological approach, this study explores how supply chain integration, agility and supply chain risk management activities influence the operational performance and robustness of supply chains.
Design/methodology/approach
Data was collected through surveys and analyzed using SmartPLS 4 and necessary condition analysis (NCA). This combined approach shifts focus from average trends to identifying the required levels of capabilities, offering insights into the necessity logic of supply chain strategies.
Findings
The study reveals that supply chain risk management and internal integration significantly influence operational performance and robustness. It also supports agility as a precursor to enhancing supply chain robustness, aligning with contemporary theoretical perspectives.
Practical implications
The findings suggest the importance of integrating risk management and internal processes to enhance supply chain performance and robustness. Additionally, agility emerges as a critical strategy in navigating disruptions, emphasizing the need to prioritize it in supply chain management.
Originality/value
By adopting a holistic approach grounded in dynamic capability theory, this study contributes to understanding the interplay of supply chain strategies amid unprecedented challenges. The combined use of SmartPLS 4 and NCA offers a novel perspective, shedding light on the necessary logic of supply chain capabilities.

Design/methodology/approach
The study is based on an experimental research design by collecting data from responses 398 responses of key officials of India’s steel manufacturing firms. Analyses are carried to explore this modern concept with the help of Smart-partial least square (PLS) version 3.3.2 with confirmatory factor analysis and PLS structural equational modelling.
Findings
SCA factor (SCAF) directly has influenced the firm’s OP. It also represents cost efficiencies that have partial mediation between the SCAF and OP. The impact of cost efficiencies on OPs is strongly significant as compared to the impact of SCAF on cost efficiencies.
Practical implications
Management teams in the manufacturing industry should stress the role of SCA as a comprehensive concept in responding to market needs in a volatile environment. SCA reflects one of its winning strategies in today’s dynamic and competitive world. Managers must thoroughly know the ramifications of agility to develop a mechanism for determining the procedures and identifying inequality in SC operation.
Originality/value
This study speaks explicitly about the linkage between SCAF, OP, CE. It is an addition to the existing theories of RBV. Enhancements in OP measurements, specifically performance and flexibility, will lead to better firm performance. study conceptualizing the complementing effects of SCA (IS capability) and OPs and second cost efficiencies play positive partial mediating effect in between the link. The achievement of SC agile is especially a critical approach to Boost customer satisfaction and differentiate market position.

Abstract
Marketing academics and practitioners have acknowledged that consumers form specific relationships with brands that are able to create unique and memorable qualities. As a result, the concept of consumer–brand relationship has been of great interest for marketers. Indeed, consumer–brand relationships are very complex and multidimensional in nature. A common perception is that brand management should create ultimate offerings and communication to have successful relationships with its consumer base. However, how consumers construe their relationships with brands is mostly out of the brands’ control. It is an emotion-intense realm and necessitates careful study of the consumers as well as the context. After summarising the current literature on brand relationships, we focus on Turkish consumers’ relationships with brands.
By focussing on a range of global and local brand studies, this chapter offers a comprehensive and well-informed analysis of the issues and practices involved in consumer–brand relationships in the Turkish context. The chapter is organised into three parts. The first part focusses on antecedents of consumer–brand relationships such as the global or local identity of the brand and brand personality. The second part presents detailed explorations of various brand relationships such as brand love and brand trust. The third and the final part focusses on an important phenomenon, the stage for various brand relationships, being online brand communities. The chapter concludes with the future research directions in these three main areas together with a discussion of offline and online branding opportunities in the Turkish market.

Abstract
Purpose
This study aims to examine the dietary compliance of children and adolescents with celiac disease (CD) and their diet quality (DQ) and dietary acid load (DAL) and to determine the relationship of these dietary parameters with health-related quality of life (HRQoL).
Design/methodology/approach
Ninety-one children and adolescents with CD and 144 healthy peers were included in this cross-sectional study. Anthropometric measurements were conducted by researchers. DQ and DAL were calculated from participants’ 24-h dietary recall records. HRQoL was assessed using the Pediatric Quality of Life Inventory, and compliance with a gluten-free diet (GFD) was obtained using the GFD score. Data was collected through a face-to-face questionnaire.
Findings
Of celiac patients, 53.1% were strictly compatible with the GFD, and 35.8% were non-compliant with the diet. The DQ scores of participants with CD were higher than their healthy peers, and the DAL scores were lower (p < 0.01). Finally, no relationship was found between the DQ and DAL with HRQoL scores in celiac patients (p > 0.05). However, better dietary compliance with the GFD was associated with improved HRQoL (p < 0.05).
Practical implications
While DQ and DAL had no association with HRQoL, better dietary compliance improved the HRQoL of celiac patients. This may help develop solutions to the problems experienced by celiac patients, thereby improving the management of CD.
Originality/value
To the best of the authors’ knowledge, this study is the first to investigate the association of DQ and DAL with HRQoL in children with CD.
