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.

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.

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.

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.

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.

In this article, the impact displacement due to war conditions has on children and their families will be explored with particular focus on Syrian children and families. It is observed that during local, regional and/or global wars, those who suffer most are the non-combatant civilians, particularly families and children. This phenomenon was observed in 2010 when protests against the economic situation triggered the Arab Revolt. These revolts commenced in Tunisia, eventually spreading to other parts of the Middle East. In the midst of these events the Syrian issue acquired great importance. The demonstrations which began in 2011, aiming at Başşar Al-Asad's resignation from his post in Syria, started as an internal war. However, they eventually led to the involvement of other regional and trans-regional actors, turning into a crisis. The unrest now continues as a low-profile crisis. As in previous wars, civilians, especially families with children, have been the main victims in Syria. The intense fighting and increasing terrorist activities forced most non-combatant Syrian civilians and families with children to flee their country. Most opted to immigrate to safer countries, particularly Turkey and in Europe, searching for better living conditions. This article highlights the bad experiences Syrians had when they immigrated. Existing Turkish and European policies might be amongst various factors which trigger immigrants' bad experiences. They require closer observation so one can better understand the processes in action. Against this backdrop, this paper examines how Syrian children have been affected by the internal war in their country, which has been ongoing since 2011, and how Turkey treats Syrian children as part of its humanitarian-oriented immigration policy.

The well-being of individuals is an essential issue of sustainability research. This study aims to focus on the particular case of teleworkers and the work conditions which may hinder their well-being. More specifically, this study analyses the impact of social isolation and work overload on the work engagement and life satisfaction of teleworkers during COVID-19 pandemic.

With a sample of 188 workers from the Portuguese banking sector, the authors use structural equations modelling to test a conceptual model. The authors carry out data analysis with partial least squares.

Social isolation and work overload are both negatively associated with the three dimensions of work engagement, namely, vigour, absorption and dedication. In turn, vigour is positively associated with life satisfaction. Social isolation and work overload are indirectly associated with life satisfaction through vigour. Results from multi-group analysis show that the negative relationship between social isolation and dedication is stronger for less senior teleworkers. By contrast, the negative relationship between work overload and dedication is stronger for more senior teleworkers. Additionally, the positive relationship between vigour and life satisfaction is stronger for permanent workers than for temporary ones.

This study tests the assumptions of the job demands-resources under the novel conditions of telework during COVID-19, focusing its ubiquitous conditions – social isolation and work overload. For human resources managers, this study highlights the need to take seniority and job stability in consideration when devising onboarding and working arrangement strategies for teleworkers.

Under the background of low consumer financial knowledge and accumulated credit card liabilities, this study investigates the relationship between financial knowledge and responsible credit card behavior using data from the 2019 China Household Finance Survey (CHFS). From the perspective of consumer economic well-being, this study defines accruing credit card debt to buy houses and cars when loans with lower interest rates are available as irresponsible credit card behavior.

This study uses probit regressions to examine the association between financial knowledge and responsible credit card behavior because the dependent variable is a dummy variable. To alleviate endogeneity problems, this study uses instrument variables and Heckman’s two-step estimation. Furthermore, to explore the potential mediators in this process, this study follows the stepwise regression method. Finally, this study introduces interaction terms to examine whether this association differs in different groups.

The results indicate that financial knowledge is conducive to increasing the probability of responsible credit card behavior. Mediating analyses reveal that the roles of financial knowledge occur by increasing the degree of concern for financial and economic information and the propensity to plan. Moderating analyses show that the effects of financial knowledge on responsible credit card behavior are stronger among risk-averse consumers and in regions with favorable digital access.

This study measures responsible credit card behavior from the perspective of the consumer’s well-being, which enriches practical implications for consumer finance. Furthermore, this study explores the potential mediators influencing the process of financial knowledge that affects responsible credit card behavior and identifies moderators to conduct heterogeneous analyses, which helps comprehensively understand the nexus between financial knowledge and credit card behavior. By achieving these contributions, this study helps to curb the adverse effects of irresponsible credit card behavior on consumers’ well-being and the economic system and helps policymakers promote financial knowledge to fully prevent irresponsible credit card behavior.
