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.

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.

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

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 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.
