Abstract
Purpose
This study aims to examine the relationship between public sector education expenditure and the GINI coefficient as a measure of injustice in income distribution.
Design/methodology/approach
Data from 31 European countries gathered from 2004 to 2011 were analyzed using panel error correction models.
Findings
According to the study’s findings, a relationship between education expenditures and the GINI coefficient exists. There is a 1 per cent increase for the European countries examined in this study in their rate of education expenditure in gross domestic product (GDP), which raises the GINI coefficient by 0.20 per cent in the short-term and decreases it by 0.22 per cent in the long-term, as expected. Thus, an increase in the proportion of education expenditures in GDP affects the GINI coefficient in a statistically significant, negative way over the long-term.
Originality/value
This study fills a gap in the literature by determining whether the interaction between education expenditure and GINI coefficient changes in the short- and long-term. The results show that education expenditure generates positive results particularly by lowering income inequality in the long-term. This interaction can be more clearly observed in developing countries. So this conclusion adds an important empirical evidence to the literature and it may contribute in forming policies toward reducing income inequality.

Abstract
Purpose
This study aims to investigate what Turkish Airlines as a global airline company reports for corporate social responsibility (CSR) efforts on its corporate website by developing a framework assessing reports of airline companies’ CSR practices.
Design/methodology/approach
Content analysis was conducted on reports, documents and written policies published on the Turkish Airlines corporate website by the end of 2017.
Findings
The research findings suggest that Turkish Airlines publishes numerous reports highlighting their CSR activities. The study results show that Turkish Airlines reports its CSR activities through reports, documents and written policies. While the CSR reporting efforts deal with all CSR areas, the environmental dimension is the mostly emphasized area.
Practical implications
The study provides a model and data-driven analyzes for decision-makers and policymakers.
Originality/value
As one of the first study in the field, this research examines CSR reporting efforts in the airline industry via a new framework developed for airline companies.

Abstract
Purpose
Sustainable tourism is becoming more popular all over the world. Eco-friendly (green) hotels are properties that are friendly to the environment and are becoming increasingly popular among green travellers. Electronic word-of-mouth is a technique of communicating with consumers in order to share their experiences, and it is a significant marketing tool for hotels. This paper aims to identify the main themes shared in online reviews by tourists visiting eco-friendly hotels, and which of these themes were associated with satisfaction and dissatisfaction ratings.
Design/methodology/approach
The research used qualitative content analyses to analyse 1,202 user-generated content of the top 10 hotels in UK shared by guests on an online platform.
Findings
The analyses revealed nine themes in descriptions of airline travel experiences. These are “hotel amenities”, “services”, “location”, “staff”, “eco” (eco-friendly activities), “value” and “recommend/revisit” (intentions). Negative comments are associated with the “bathroom”, “mattress”, “water”, “bed”, “price”, “shower”, “Wi-Fi” and “restaurant” concepts.
Originality/value
This study differs from previous research in which it aims to address a void in the literature on the shortcomings of research focused on finding the dominant themes expressed in online reviews by tourists visiting eco-friendly hotels, and it does so using data mining approach.

Abstract
Purpose
Considering both the current opportunities of the Internet of things (IoT) and aviation, as well as the potential opportunities they may offer for the future, it is understood that they are among the important issues that need to be examined in the literature. This study aims to provide an idea by conducting bibliometric and visualization analyses of the current trends and development opportunities of IoT and aviation.
Design/methodology/approach
In this study, descriptive and bibliometric analyses within the framework of co-author, co-citation, bibliographic coupling, and keyword co-occurrence analysis were carried out for publications found to be published between 2007 and 2023 in the Web of Science (WoS) database related to IoT and aviation. VOSviewer (ver. 1.6.18) program and the Biblioshiny application were used to create bibliometric networks and provide visualization.
Findings
As a result of some descriptive and visualization analyses, the current trend of publications on IoT and aviation and future publication opportunities has been revealed. It has been understood that the subject of IoT and aviation is one of the subjects whose number of publications has increased in recent years and has not yet fully matured in terms of the number of publications and has the potential to make new publications.
Originality/value
In this study, bibliometric analysis of IoT and aviation, which could not be found examined before in the literature, and the creation of existing bibliometric networks by visualizing were carried out.

Abstract
Purpose
During the past several years, research and studies in the field of solar energy have been continuously increased. One of the substantial applications of solar energy is related to industrial utilization for the drying process by efficient heat transfer methods. This study aims to upgrade the overall performance of an indirect solar dryer using a solar absorber extension tube (SET) equipped with ball-type turbulators.
Design/methodology/approach
In this work, three various SETs including hollow (SET Type 1), 6-balls (SET Type 2) and 10-balls (SET Type 3), have been simulated using Fluent software to evaluate heat transfer characteristics and flow structure along the air passage. Then, the modified solar drying system has been manufactured and tested at different configurations.
Findings
The findings indicated that adding a SET improved the performance notably. According to the results, using turbulators in the tube has a positive effect on heat transfer. The highest overall thermal efficiency was found in the range of 51.47%–64.71% for the system with SET Type 3. The maximum efficiency increment of the system was found as 19% with the use of SET. Also, the average specific moisture extraction rate, which is a significant factor to survey the effectiveness of the dehumidification system was found between 0.20 and 0.38 kg kWh−1.
Originality/value
In the present study, a novel SET has been developed to upgrade the performance of the solar dehumidifier. This new approach makes it possible to improve both thermal and drying performances.

Abstract
Purpose
The purpose of this paper is to provide an organizing lens for viewing the distinct contributions to knowledge production from those research communities addressing the impact of competitive strategy on company performance in general, and the influence of cost leadership and differentiation strategy on organizational performance in detail.
Design/methodology/approach
The research methodology was based on the PRISMA review, and thematic analysis based on an iterative process of open coding was analyzed and then the sample was analyzed by illustrating the research title, objectives, method, data analysis, sample size, variables and country.
Findings
The main factor that influenced the competitive strategy is strategic growth; strategic growth has a significant influence on competitive strategy. Furthermore, competitive strategy will boost firm network, performance measurement and organization behavior. In the same way, the internal goal factor will enhance organizational effectiveness. Also, a differentiation strategy will support management practice factors, strategic positions, product price, product characteristics and company performance.
Originality/value
This study contributes to the literature by identifying a framework of competitive strategy factors, company performance factors, cost leadership strategy factors, differentiation strategy factors and competitive strategy with global market factors. This study provides a complete picture and description of the resulting body knowledge in competitive strategy and organizational performance.
