Abstract
In this paper, we present a more sensitive quantification of the high performance liquid chromatographic (HPLC) method to analyze juglon in madder root (Juglans regia L. or walnut) which appears in the South of Anatolia. The juglon is separated on a Zorbax Eclipse XDB C18 column with a phosphoric acid-acetonitrile gradient as eluent and measured with UV detection at 250 nm. With this method, the juglon can be analyzed. The regression equation that is obtained from the calibration curve reveals a linear relationship (r = 0.9999) between the mass of the juglon injected and the peak area. Then, the color component responsible for dyeing is determined and its chemical constituents are established based on chemical and spectroscopic investigations. Afterwards, the wool fabrics are dyed by using pre, together and last mordanting, and mordantless techniques. Fastness to light, washing and rubbing of the dyed fabrics are measured and discussed.

Abstract
For the last several decades, technology has been playing an important role in changing the lives of consumers with an unexpected speed of innovative developments. Most of them were disruptive and had shaped not only the behaviour of consumers, but also empowered them to search for better products and services. These changes took place in media, communication, and information management of socialisation and collaboration. The digitisation revolution is a continuum until people and machines embrace a common ground for improving the lives of consumers. There were three stages of this movement. In the first stage, Turkish perspective was in alignment with the world where new channels of communication were established with support of Internet and information management. Marketing technology tools such as customer relationship management and call centre systems were discovered. In the second stage, continuous learning from the best uses and implementations has started. The ultimate goal became total customer satisfaction. Many improvements and innovative services, such as omni-channel marketing, took place for achieving this goal. Today, in the third stage, new marketing tools are being developed on the basis of integrated machine learning, such as analysis of customer conciseness, prediction of behaviour and perceptive marketing, which will be used extensively through digital platforms, new media, social web and in everyday devices for targeted marketing. In this chapter, a broader look is taken and an explanation is made for what has happened through these periods of intersection of marketing science and information technology. Moreover, ongoing changes which have given a new impetus to consumer life are addressed with respect to marketing management literature.

Abstract
Purpose
Anchored mainly on the institutional theory and resource-based view, this study endeavors to investigate the interplay between home country institutional environment (economic, regulatory and socio-cultural environment), export market orientation and export performance. Besides, this study also aims to examine the moderating role of firm resources (knowledge-based and managerial resources) in the associations between home country institutions and export market orientation.
Design/methodology/approach
Drawing on data from a sample of 221 exporting firms in Turkey, the conceptual model is empirically examined by structural equation modeling.
Findings
The findings reveal that regulatory environment is conducive to the improvement of export market orientation, which is instrumental in cultivating export performance. Importantly, empirical evidence also proves that higher levels of knowledge-based and managerial resources strengthen the linkage between home country institutions and export market orientation.
Originality/value
Integrating institutional theory with the resource-based view, this research considerably contributes to the current understanding of the export market orientation phenomenon by filling the knowledge gap on the differential impacts of home country’s economic, regulatory and socio-cultural environment on export market orientation. Moreover, this study provides worthwhile insights into the moderating effect of knowledge-based and managerial resources on home country institutions and export market orientation and the interrelationship between export market orientation and export performance in an emerging economy.

Abstract
Purpose
The purpose of this study is to determine the relationships between organizational justice, organizational silence and organizational creativity and to examine the mediating role of organizational silence in the effect of organizational justice on organizational creativity.
Design/methodology/approach
Research data were collected using a face-to-face survey method applied to employees in the automotive industry in Turkey. The research model and hypotheses were tested by structural equation modeling.
Findings
Research results indicate that organizational justice positively affects organizational silence, organizational creativity is positively affected by organizational justice and organizational silence positively affects organizational creativity. Besides, according to the results, organizational silence has a partial mediating role in the effect of organizational justice on organizational creativity.
Originality/value
Although the relationships between organizational justice, organizational silence and organizational creativity were examined in previous studies in the literature, the role of organizational silence in the relationship between organizational justice and organizational creativity was not investigated. Besides, although previous studies examined the mediating role of variables that are thought to have a positive effect on the organization between organizational justice and organizational creativity, they did not study the role of a variable of organizational silence, which is considered negative. For these reasons, this study is predicted to differentiate the perspective in the literature and fills a gap in the literature.

Abstract
The chapter examining the impact of artificial intelligence (AI) on audit quality to achieve business sustainable practices, trying to found that using of AI as a substitute for human intelligence affects auditor’s capability and experience, from other hand affects audit process, starting from audit planning until issuance of reporting. Based on literature review about AI and audit quality, the chapter findings showed that AI adoption is a necessary requirement for auditors due to time constraints, accuracy requirements, and job speed requirements. The impact of AI on audit quality is profound and multifaceted. By leveraging the capabilities of AI, auditors can enhance the accuracy, efficiency and objectivity of their work.
To guarantee that the application of AI benefits the auditing profession and the public it serves, it is imperative to solve the obstacles that come with it. AI has the ability to greatly improve audit quality, but its deployment needs to be closely monitored to prevent any early problems. With appropriate training, data, and governance, AI can enhance the efficiency and effectiveness of audits, leading to more accurate and reliable financial reporting. However, it is important for auditors to be aware of the challenges and risks associated with AI and to take steps to mitigate these risks. Where cybersecurity is a protection line for external threats and it is considered as a new risk management tool.

This study aimed to design a user-participatory methodology to investigate the post-occupancy sustainability of reused historical buildings and to apply it to a case study.
Abstract
Purpose
This study aimed to design a user-participatory methodology to investigate the post-occupancy sustainability of reused historical buildings and to apply it to a case study.
Design/methodology/approach
This study was designed in four stages. In the first stage, the sustainability parameters and sub-parameters were determined in the reused historical buildings based on the literature. The second stage included a field study in which the current situation of the study area was analysed, and the users were reached using the survey technique. In the third stage, the data obtained from the user participation were analysed with importance performance analysis (IPA) and an IPA matrix was created. The fourth stage included an evaluation of the results of the analysis and the development of recommendations.
Findings
IPA is a supportive method for ensuring the sustainable use of historic buildings. According to the data obtained from the IPA, it was seen that the functional sustainability of the building was achieved to a great extent. At the same time, there were deficiencies in technical and environmental sustainability. In terms of aesthetic sustainability, it was observed that the importance and performance values given by the users were generally consistent with each other.
Originality/value
The originality of this study is that the performance of the reused historical buildings in the process of use was monitored with appropriate parameters, and a user-participated method was proposed that allows improvement suggestions to be developed in line with the results obtained.
