This study provides a summary of empirical findings of necessary papers in this field and try to assist researchers who are interested in this issue during their preliminary research.

The aim of this study is to determine the causality relationship between energy prices, which are among the most important inputs of the economy, and selected stock market indices of developed countries. Crude oil and natural gas are used as energy variables. G7 countries were selected to represent developed countries. Stock indices used in the study are Dow & Jones (USA), DAX (Germany), CAC40 (France), FTSE250 (England), FTSE Italia All Share (Italy), NIKKEI225 (Japan), and S&P/TSX (Canada). In the study, Johansen (1988) cointegration test and Granger (1969) causality test were used to analyse the causality relationship between energy prices and selected stock market indices. The research could not find a long-term balance relationship between energy prices and developed country indices. Also, while the causality relationship was determined between crude oil prices and NIKKEI225, DAX, and CAC40 indices, a causal relationship between natural gas prices and Dow & Jones and FTSE250 indices was determined. In the study, it was found that energy prices can be used for diversification in investments to be made with stock market indices of developed countries. This study is one of the most comprehensive studies in the literature that examines the relationship between energy prices and the stock market indices of G7 countries. It is expected to contribute to the literature in this way.

When we hear the word diversity, usually the first word that comes to mind is difference, and diversity steams from difference, in this paper, board diversity is discussed, in addition to linking it to firm performance, diversity is important, and it’s especially important in the board room of a given firm because it allows for different perspectives and opinions which can impact the decision-making process in the firm, which ultimately can affect the performance of the firm. The purpose of this paper is to give a relational guide on how board diversity can greatly impact the achievements of a firm. This paper is a theory-based study and aims to develop a critical approach of defining board diversity and linking that to the performance of the firm. This paper is a theory-based study because it utilizes the existing literature in order to determine the impact of board diversity on firm performance. This study also uses different theories and existing literature to highlight the relevance of having a diverse board in the firm. To find the relation, various studies and existing literature were analyzed to develop a critical approach to relate board diversity to firm performance. In conclusion, this paper outlines different aspects of board diversity while providing a critical look that allows us to assess the importance of board diversity and its connection to firm performance.

Air cargo transportation in international trade stands out with its speed, reliability, safety, interaction with other transportation types, intensive use of information technologies, and global standards. During the Covid-19 pandemic, various negativities have emerged in air cargo transportation, as in many sectors. In this study, the difficulties caused by the Covid-19 pandemic in air cargo transportation business processes are evaluated within the scope of the ISO9001 Quality Management System standard so that they do not adversely affect the service quality. In this context, a case study was conducted on the implementation of the ISO 9001 Quality Management System standard in dealing with the difficulties arising from the pandemic in the cargo operations of an air transportation company. As a result of the implementation, the cargo ecosystem has been expanded, the carrying capacity has been increased, and the storage and cargo transportation efficiency has been increased by making use of information and communication technologies. Thus, it was easier to overcome the difficulties arising from the pandemic in the business processes of the company, and it was seen that sustainability in line with commercial expectations was ensured by rising to fifth place in world air cargo transportation in 2020.

This paper aims to examine the impact of Covid-19 pandemic on stock markets. This paper also analyses the stock market cointegration of selected global equity indices that performed better and have a quick speed of recovery during the pandemic. This paper also questions how increasing uncertainty and volatility deters investors’ perception of the diversification of equity investments. The dataset for the selected 12 global equity indices has been used from Thompson Reuters’s EIKON database in a given period of time between 2010 and 2021. This paper employs Vector Error Correction Models to assess the relationship among the selected global equity indices. Findings demonstrate that (i) there is an adverse impact of Covid-19 on the Global Equity markets, (ii) there is a clear sign of cointegration in global equity indices, (ii) investors can benefit from investing in particular equity indices that have exhibited quick speed of recovery from the pandemic records lows. The findings finally provide a strong foundation for constructing a resilient equity portfolio in a highly uncertain market environment.

This paper aims to develop a critical approach to flight safety by assessing theoretical and empirical studies on fatigue risk factors in cockpit and cabin crew. This paper also builds a fundamental basis for managing fatigue risk factors in the aviation industry. The main contribution of the paper demonstrates the fact that primary and secondary fatigue risk factors in cockpit and cabin crew affect the level of job satisfaction, operational efficiency, and flight security.

This study aims to develop a theoretical approach to define the culture of peace and its dimensions in the workplace based on De-Rivera’s peace culture dimensions at the international level. This study offers an organizational model in the workplace and it needs empirical tests in further studies. This paper is an attempt to develop a theoretical framework for peace culture in the workplace. Peace culture will be analyzed in four underlying dimensions: liberal development, violent inequality, state use of violent means, and nurturance. This study transfers De Rivera’s peace culture dimensions into the organizational level, and it is assumed that peace culture in the workplace could be a remedy for a harmonious and peaceful workplace. Peace culture in the workplace is also expected to be a beneficial factor to employees’ behavior, job performances, and organizational commitment as well as work outcomes. In a conclusion, it is expected that this study fills the gap in the literature and will have a leading role for further studies

Cryptocurrencies are attracting considerable attention around the world because of the various advantages that they offer. On the other hand, they also carry some inherent risks. Although monetary authorities broadly agree that cryptocurrencies do not engender an immediate threat to national and global financial systems, the future is full of unknowns. In this regard, drawing a framework based on the current drivers of demand for cryptocurrencies would help visualize the prospects for these assets and create a roadmap to avoid or manage any disruptive risks. This discussion paper aims to contribute to the literature by examining the key factors that will determine the future performance of cryptocurrencies. The main conclusion derived from the discussion is that national regulations will potentially affect the direction of cryptocurrencies, as well as the need for any special efforts in the domain of monetary policy

Air cargo transport is a growing industry in parallel with the growth in world trade and e-commerce. The global air cargo transport traffic getting busier, the importance of timely loading with minimum error is increasing. Therefore, digitalization of the air cargo loading process is needed. Assignment of Unit Load Devices (ULDs) to the specific positions on the freighter is performed by loadmasters by manual or semi-manual methods. This study aims to design a simulation model, which performs the ULD assignment automatically by simulating the loading process performed by the experienced loadmasters under the weight and balance constraints. The SEMMA (sample, explore, modify, model, assess) model is used while generating the simulation model. Fifty real-world loading orders were used to assess the performance of the model. The ULD assignment process by the simulation model and the loadmasters using semi-manual loading were compared with regard to time and center of gravity performance indicators. The results demonstrated that the simulation model can load all the given sets of ULDs, as efficiently as a loadmaster with a similar center of gravity in a shorter period of time. In conclusion, the proposed simulation model provides an efficient solution to the ULD assignment problem. However, the base model generated may be improved to address various real-world scenarios

Fatigue as an emerging flight safety issue in the aviation industry requires an elaborate understanding and critical approach for proactive aviation management practices. The level of flight crew stress and fatigue must be critically managed to prevent flight accidents. Additionally, stress and fatigue have a negative influence on job satisfaction levels. This paper aims to examine the critical fatigue risk factors that affect the performance and safety of airline pilots and crew in the aviation industry. This paper also analyses the relationship between burnout and job satisfaction sub-dimensions. A factor analysis with a target population of 254 international flight crew has been conducted using the Minnesota Job Satisfaction Survey and Maslach Burnout questionnaire. The main findings of the study demonstrate that (i) cockpit and cabin crews’ job satisfaction and performance have been affected by stress and fatigue, (ii) psychological depression, anxiety and personal problems of the flight crew are the main causes of emotional fatigue, (iii) extensive flight hours and dealing with problematic passengers increase flight crew fatigue, (iv) personal achievements concerns and depersonalization increase flight crew fatigue.

This paper aims to examine the impact of mobile telecom service characteristics on consumer satisfaction in urban Uganda, using a Servqual model. The association between customer satisfaction level and service quality characteristics has been tested with a regression analysis. In this study, assurance as a Servqual dimension has been substituted with tariffs to exhibit its effect on customers’ satisfaction levels. Findings verified that some of the Servqual dimensions including reliability, empathy, and responsiveness have been positively affecting the customer satisfaction level in the Ugandan context. The study also demonstrated that the prices of products and services of telecom companies were not the major concerns for telecom consumers in Uganda. The study, finally, provides some practical guidelines to managers of telecom companies as well as hinting out which Servqual dimensions are valued most by customers in Uganda.

The Turkish social insurance system has been feverishly debated for years, particularly through its burden on the economy. The most recent reform is an attempt to neutralize the deterioration within the social security system and its effects on the economy. After the recent reform, ‘the way that retirement benefits are calculated’ is changed unfavorably for workers and the minimum age for retirement is increased. In particular, for an agent with 25 years of social security tax payments, the replacement rate is down from 65 percent to 50 percent. On the other hand, retirement age is up from 60 to 65. The aim of this paper is to investigate the macroeconomic effects of these changes using an OLG model. The author’s findings indicate that labor supply, output and capital stock increase when changes above are applied to the benchmark economy calibrated to the Turkish economy data in 2005. A critical change with the current reform is that the marginal benefit of working has become uniform over ages. In a simulation exercise, the marginal retirement benefit in the benchmark economy is changed to be uniform over ages while keeping the size of social security system unchanged. As a result, the benefit of retiring at a later period increases. However, uniform distribution of the marginal benefits itself decreases both the capital stock and output of the economy. Increasing the retirement age has positive effects on the economy since agents obtain retirement benefits for fewer years and at an older age.

The purpose of this study is to investigate the impact of stock splits on the return, riskiness, and liquidity of stocks. Utilizing a sample of 94 stock splits taken place between 2010 and 2019 at Borsa Istanbul, the study analyzes the daily abnormal returns, change in volatility, and changes in volume around the stock split announcement and execution dates. The results display significant positive abnormal returns around the announcement date but not significant abnormal returns around the execution. The volatility and liquidity of stocks increase significantly around both announcement and execution dates. The findings are in line with the positive signaling, and liquidity hypotheses of stock split and with most of the observations reported in the empirical literature. The new evidence provided points out the lack of semi-strong form of market efficiency at Borsa Istanbul as far as the stock splits are considered.

 The purpose of this exploratory study has been to provide insight into the success factors of ECF campaigns and, in particular, explore the role of trust. In specific, the research questions for this study are: (1) What dimensions of ECF success have been studied so far, and (2) is there any established literature on sustainability, blockchain technology and trust in the realm of ECF.  To that end, a systematic literature review is conducted by investigating ISI Web of Science and Scopus, two major academic databases, through relevant keyword combinations. The theoretical framework relies on signaling, legitimacy and stakeholder theories. Findings indicate that the role of trust is an emerging theme, and sustainability and BT in relation to trust, to the best of the author’s knowledge, is not yet focused upon in crowdfunding research. This study contributes to the literature of crowdfunding and entrepreneurship.

As Covid-19 lockdown forced firms to organize work differently, for example, managing people remotely.  Despite the benefits may a firm obtain in adopting new business tools like remote management, but providing assurance that internal control function in an efficient manner is important for a firm; that is because there is a growing interest in internal control issues. It is very important to determine how the remote working model, which emerged during the Covid 19 pandemic process, has changed the accounting processes of businesses. The aim of this study is to propose an internal control model under factors such as remote management, risk assessment, control activities, information and communication, and observation. The data in the research were obtained from the experts in our sample by using the survey method. Our sample consists of managers, supervisors, and academics. The data obtained were evaluated with the Smart-PLS version 3.2.9 program. Findings highlight a positive relationship between control activities and remote management.  

Toxic leadership refers to the sum of the negative aspects of leaders within their leadership traits. Narcissistic leadership is a multidimensional structure that includes charismatic leadership and authoritarian leadership types. Toxic leaders can harm the organization, employees, and society in which they work. This research aims to determine the toxic characteristics of leaders working in public universities and to extract the attribute of organizational trust in job satisfaction. Turkey's Istanbul made the data collected through face-to-face survey research methods in 470 people working in the public university hospital in the province were analyzed by analysis methods used in social sciences. As a result of the analysis, a negative significant relationship between toxic leadership and organizational trust, a negative significant relationship between toxic leadership and job satisfaction and its sub-dimensions, and a positive significant relationship between organizational trust and job satisfaction and its sub-dimensions were found. Toxic leadership affects managerial job satisfaction and company policy-based job satisfaction through the full set of organizational trust. In addition, toxic leadership has also been found to be effective on job satisfaction arising from employees through partial organizational trust

In this study, the fear created by the Covid-19 global epidemic on consumers (general fear of viruses and fear of activity), spending (cleaning products, preventive health products, fresh and organic food and vitamin/mineral support, clothing, education, home purchasing, vehicle, loan. The relationship between buying, rental, fashion, vacation, travel, entertainment, electronics, home decor/furniture, mobile phone, activity and general) and savings have been tested. For this purpose, in order to test the relationship between fear, saving, and spending during the Covid-19 pandemic process, a Likert-scale online survey link was shared on social networks (Twitter, LinkedIn). The total of 385 surveys was analyzed using Google Form and SPSS program (Anova, Regression). As a result of the analysis, fear (general fear and fear of activity), spending (education, vehicles/cars, monopoly products, and tobacco products, games of chance, home buying and renting, loans, luxury/fashion, games, and toys, vitamins, minerals, and food support, public services, home, and furniture décor, electronic products (including mobile phones) expenditures remained the same, protective healthcare products, cleaning products, fresh and organic food expenditures increased, travel, public transportation expenditures decreased, holiday and entertainment expenditures decreased significantly). In the research, it was determined that 42% of the participants increased their savings by 30.5% slightly, and the amount of savings did not change at all for 27% of the participants. According to the results, as consumers' fear of Covid-19 increases, some spending categories (health products, cleaning products, fresh and organic food spending) and savings rate increase. In addition, it was observed that 90% of the participants canceled their expenses due to Covid-19. As a result of the research, significant relationships were found between the variables of fear, saving, and spending during the Covid-19 pandemic process.

  This study examines the relationship between organizational justice and organizational ambidexterity with organizational learning. This paper also evaluates the effect of organizational justice on organizational learning strategies of employees in the cause-effect relationship and measure the effect of perceived organizational support and bi-directionality on organizational learning. 645 family firms operating in Istanbul have been analyzed with Structural Equation Model. Findings demonstrate that organization's ambidexterity ability and the concept of justice in the organization had an indirect and positive effect on the perception of organizational support. This study also highlights that companies using their generic knowledge and skills increase the effectiveness of their innovation activities. The exploratory and development capabilities of a company make a significant contribution to the personal development of the employees in the company.
