Abstract
Purpose
To investigate the effects of regulations, macroeconomic changes, and political events on the efficiency of the Turkish banks during the period 1997-2013, when crucial changes were experienced. To analyze the effects of an extensive set of bank-specific and environmental factors on the efficiency, since the diversions could not only be related to new regulations.
Design/methodology/approach
A two-stage procedure is employed. First, the productivity changes of each bank and of the whole sector are measured by a DEA-based Malmquist Productivity Index (DEA-MPI). Second, the effects of selected internal and external factors on productivity are analyzed with regression analysis. The sector is especially handled before and after 2001, when one of the most catastrophic crises is observed and moment after which a series of new regulations are implemented.
Findings
During the period 1997-2001, the efficiency deteriorated due to the 2001 crisis; after the crisis, an improvement was observed. All models indicate the source of improvements as efficiency instead of technological changes. Rather than external, internal factors seem to be more effective on productivity. Therefore, the importance of regulations for the soundness of banks, management quality and monitoring may be more crucial than what is thought. In general, a new macroeconomic environment, particularly new regulations, have positive effects on productivity. Tighter regulations, monitoring, restrictions, strong supervision, more capital, and new reforms have a positive impact on efficiency.
Originality/value
The study spans a wide period to analyze the sector using three different perspectives. It analyzes the effect of the 2001 financial crisis and subsequent regulations. It handles an extensive set of internal and external factors; and it tests each factor with nine different DEA-MPI models for consistency. Turkey's unique environmental factors, such as the unstable macroeconomic conditions, high inflation and a subsequent disinflation period, high interest rates, new regulations and crisis experience, among others, also make the study distinctive.

Abstract
Purpose
This study aims to determine the attitudes of Turkish consumers toward Islamic mobile shopping apps and discuss whether these apps will need to be designed in accordance with Islamic rules in Muslim countries or not in the sample of Turkey.
Design/methodology/approach
A descriptive study was used. The data was collected online through a questionnaire form. The one-sample t-test and univariate analysis of variance were used to analyze the data obtained from 379 individuals.
Findings
The results show that Turkish customers have mostly positive attitudes toward Islamic mobile shopping apps and demand that the pictures, videos and advertisements used on mobile shopping apps be in concordance with Islamic rules. As a result of this study, consumers do not mind the colors or lean toward the use of models on Islamic mobile shopping apps. Furthermore, there are differences between gender with regard to using Islamic mobile shopping apps, showing that male consumers have a more positive attitude toward Islamic mobile shopping apps compared with female consumers.
Research limitations/implications
Like many previous empirical studies, this study has limited its context to capture a particular geographical area. Moreover, in this study, the data are obtained by judgmental sampling as a nonrandom sampling method. The contributions of the current study are restricted to Islamic mobile apps for the hijab clothing sector in Turkey.
Practical implications
The results obtained can become a yardstick to measure consumer attitudes toward Islamic mobile apps’ attributes.
Originality/value
The primary benefit is to call the attention of mobile app designers to the design features of mobile shopping apps aimed at Muslim users. The second benefit is to determine the expectations of Muslim users regarding the design of Islamic mobile shopping apps, and eventually establish the fundamental Islamic design features needed to be available on new Islamic mobile shopping apps.

Abstract
Purpose
The use of unmanned aerial vehicles (UAVs) has significantly increased in the past decade and nowadays is being used for various purposes such as image processing, cargo transport, archaeology, agriculture, manufacturing, health care, surveillance and inspections. For this reason, using the appropriate image processing method for the intended use of UAVs increases the study’s success. This study aims to determine the most suitable one among the innovative methods that constitute the image processing system for a UAV to be used for surveillance purposes.
Design/methodology/approach
Analytical hierarchy process has been used in the solution of the decision problem to be handled in three stages, namely, platform, architecture and method. The most suitable alternative and the effect weights of these criteria results were determined at each stage.
Findings
As a result of this study, Jetson TX2 was determined as the most suitable embedded platform, ResNet is the optimum architecture and Faster R-convolutional neural networks was the best method in the image processing layer for a system that will provide surveillance with image processing method using UAV.
Practical implications
In UAV designs, where multiple hardware and software choices and system combinations exist, multi-criteria decision-making (MCDM) approaches can be used as a system decision mechanism.
Originality/value
The novelty of this work comes from the application of MCDM methods that are used as a multi-layered decision mechanism in UAV design.

Abstract
Purpose
This paper aims to present an example of the measurement of airport efficiency, a topic of great interest in civil aviation today. The methodology used is data envelopment analysis (DEA) and the Malmquist Index. The calculation of airport efficiency with up-to-date data for each period is of great importance in the context of sustainability. The study selected ten airports with high air traffic in Turkey as the sample set. The objective of this study is to evaluate the current state of airport efficiency, identify the sources of inefficiency and make appropriate policy recommendations based on the findings obtained.
Design/methodology/approach
The study is based on DEA and Malmquist Index Analysis. The number of personnel and terminal size data of ten selected decision-making units (DMU) are used as inputs, while passenger, cargo and aircraft traffic data are used as outputs. A five-year period, spanning from 2018 to 2022, is considered as the data set in the study.
Findings
Upon analysis of the data from the ten airports included in the study, it was found that the current input-output combination yielded efficient results, with the exception of certain characteristics, such as the impact of seasonal conditions or tourism. Concurrent with the growth in aircraft, passenger and freight traffic, the number of personnel employed at these airports has also increased. It was concluded that technological efficiency is of paramount importance for each airport, and that investments in technology should be increased.
Practical implications
A separate assessment was conducted for each of the ten airports included in the study sample. Each airport was evaluated in terms of its strengths and weaknesses, and areas of low efficiency were identified. Consequently, more general conclusions were reached than airport-specific evaluations.
Originality/value
In order to ensure the long-term sustainability of the sector, it is essential that the efficiency measurements of airports are calculated using up-to-date data on a regular basis. The results obtained from these calculations provide guidance for the strategic plans to be implemented in the long term, as well as for the solution proposals for operational problems. In this context, this study not only provides information to policymakers and airport managers about the current situation, as it includes recent data, but also contributes to the literature in this sense, as it includes policy recommendations.

Abstract
The environment in which businesses perpetuate their vital existence can be named as VUCA due to its variable, uncertain, complex and ambiguous structure. In the world of VUCA, which is far beyond the classical environmental conditions, the success of the businesses largely depends on the performance level of the staff they employ. The high or low level can be directly affected by the leadership style which the business managers will be exhibiting. Agile leadership type emerges as one of the leadership styles that could be successful in such environmental conditions. For this reason, the main purpose of this section is to provide information about the agile leadership issues that play a fundamental role in the success of businesses in today’s VUCA world, which can positively affect the employee performance and this level of performance, and, at the same time, which could be successful in these environmental conditions. In order to achieve this aim, first of all, the concepts of agile leadership, employee performance and VUCA world are explained. In the following sections, agile leadership and the relationship of this leadership style with employee performance are discussed in the VUCA world spiral.

Abstract
In this chapter, Turkish educational system and institutional quality assessment initiatives of education are explained. And also, the relationship between educational quality assurance (QA) in Turkey and issues of effective schooling is summarised in terms of Turkish literature.
Education is widely accepted as a lifelong process. The school is an institution established in order to provide qualified education which contains complex and more abstract knowledge and ideas as well as literacy and simple numerical skills to the students. Each country has basically established education systems and educational institutions to ensure social integration, continuity and stability, and to sustain the social and cultural heritage of a society. Education in Turkey is one of the state’s basic functions according to the constitution and performed under the supervision and control of the state with the declaration of the Republic of Turkey. Ministry of National Education is responsible for the implementation of all education activities centrally managed in the Republic of Turkey. Higher Education Council (YÖK) is responsible for the management and thus the quality processes of the higher education institutions in Turkey. Two major attempts in this perspective are YÖK, which assesses the institutions with standards which are coherent with international accreditation institutions, and Higher Education Quality Council (YÖKAK), an independent and specific council which is established by YÖK. YÖK and YÖKAK are governmental-based quality-assessment institutions. Association for Evaluation and Accreditation of Teacher Colleges’ Educational Programs (EPDAD) is also an independent institution for quality assessment of education faculties which focusses on teacher training and education. The purpose of EPDAD is to strengthen the student learning in formal training and to ensure the quality standards for candidate teachers. Any undergraduate programme which meets the standards of EPDAD is accredited for three years. Standards of EPDAD are detailed in this chapter.

Abstract
Purpose
The world society as a whole and Ukraine are realizing that climate change and decarbonization are critical issues. This study aims to determine whether the aviation and transportation industries in Ukraine have rearranged their priorities as a result of this investigation. The process of decarbonization and adaptation begins with a legislative point of view and then moves on to technology, improvements, infrastructure, energy and emissions stages to meet the primary goals.
Design/methodology/approach
An analysis of the content of the literature about decarbonization and the legislation and application processes for airport de-carbonization in Ukraine. The study focuses on the landing and take-off cycle of the airports. The statistics on the transportation of the Ukrainian territory have been looked at over time to determine whether or not there have been any shifts.
Findings
There are significant reduction figures found in the Poltava region. Double-figure emissions reductions in four years of series are 5.9%, 41.0% and 19.3%, in the respective years of 2018, 2019 and 2020, which is a 55.3% reduction compared with 2020 to 2017.
Practical implications
Because the transportation industry and aviation generate a significant amount of carbon dioxide, steps must be taken to cut emissions. The decarbonization process ought to proceed in the form of a series of actions to achieve carbon reduction goals with a broader range of participants. In addition, an aviation subsidy for biofuels may be required to initiate the shift by having the taxation change.
Originality/value
As far as the literature surveys, to the best of the authors’ knowledge, this is the first comprehensive Ukrainian decarbonization analysis that considers legislation, technology, improvements, infrastructure, energy and emissions in addition to just those four categories.

Abstract
Purpose
The primary objective of this study is to examine how trust and religiosity, in relation to halal products, impact Turkish consumers' intention to purchase such goods. Furthermore, the study aims to identify whether attitudes towards halal products play a mediating role in these effects.
Design/methodology/approach
Data were collected from 847 people living in Turkey using an online survey. The authors empirically tested the proposed conceptual model via structural equation modeling.
Findings
The study’s results show that trust in halal products has a positive impact on both the intention to buy halal products and the attitude towards them. Moreover, one’s attitude towards halal products affects the intention to purchase them. Additionally, one’s religiosity-belief level influences the intention to purchase halal products, while religiosity-practice level influences the attitude towards halal products. Furthermore, through indirect effect analyses, it was found that trust in halal products and religious practices has an indirect impact on intention through attitude.
Research limitations/implications
These outcomes significantly contribute to understanding the complex interactions between trust in halal products, levels of religiosity, and attitudes in shaping consumers' purchase intentions and approaches towards halal products. These implications offer valuable insights into how consumers' religious beliefs, trust perceptions, and attitudes influence their purchase of halal-certified products. Validating these conclusions on a larger scale and exploring them in different contexts would be beneficial.
Practical implications
The practice dimension of religiosity pertains to performing actions prescribed by the religion, embodying the practical applications of religious teachings. According to the research findings, the belief dimension of religiosity significantly and positively affects the intention to purchase halal products. This finding aligns with several prior studies.
Social implications
Sharing information on websites, social media platforms, or product packaging can be effective. If businesses genuinely adhere to halal standards and address the genuine needs of consumers who value halal products, they can enhance consumers' interest in such products.
Originality/value
This research was conducted in Turkey, where most people follow the Muslim faith. The main objective of the study was to examine the trust levels of consumers who have strong religious beliefs and are sensitive to consuming halal products. The study looked at trust on three levels: trust in the halal product, trust in the company that produces halal products, and trust in institutions that provide halal certification. The study also looked at the religiosity levels of the consumers using a two-dimensional approach, which included their beliefs and practices.
