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.

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 study discusses the influence of relationship conflict, turnover intention, and employee performance of Gladish Medical Center General Hospital on work burnout as a mediator. The purpose of this study is to examine and analyze the influence of relationship conflict on work burnout as a mediator on turnover intention and employee performance of Gladish Medical Center General Hospital Pesawaran. Researchers use census technique with 70 respondents who are employees of Gladish Medical Center General Hospital Pesawaran. The analytical test uses SmartPLS v.2.0 with SEM (Structural Equation Modelling) analysis method. The results reveal that relationship conflict has a positive and significant influence on turnover intention. Work burnout is proven to mediate the influence of relationship conflict on turnover intention. While relationship conflict has no significant influence on employee performance. Work burnout is proven to mediate the influence of relationship conflict on employee performance. Relationship conflict has a positive and significant influence on work burnout. Work burnout has a positive and significant influence on turnover intention. Work burnout has a negative and significant influence on employee performance.

Despite the institutionalization of operational risk management in banks and the strict supervision of bank regulators, operational risk events are still on the increase. It is becoming evident to banks that there is a need to identify the drivers of this risk and nib it at the root to reduce the probability of recurrence. Hence, this study examined the drivers of operational risks in Nigerian commercial banks and the extent to which each driver contributes to operational risk. To achieve the study’s objectives, primary data were collected from the Operational Risk Management Desks of six (6) sampled commercial banks and analyzed using SPSS and Microsoft Excel. The result showed that Internal processes, IT systems and Quality of Risk Officers are determinants of operational losses in banks. The internal process was however indicated as having the most impact. The study concluded that Internal Process is the major driver of operational risk in Nigerian Commercial banks. The researcher, therefore, recommends that bank management must have defined procedures for core activities and prioritize regular review of their critical processes to reduce operational risk events and the associated costs.

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.

This article review provides an insight into the main signals that will be responsible for the coming recession that will start from developed countries and will reflect negatively on developing countries that witness a decreasing level of development. The paper starts with the main seven signals that will initiate the recession. The second section will provide an analysis of the applied procedures and the economic reform that the government adopted to attract investment to overcome the previous and the coming challenges. Finally, the paper provides future expectations and paths for developing countries to overcome the recession.

There is a pool of techniques and methods in addressing dynamics behaviors in higher frequency data, prominent among them is the ARCH/GARCH techniques. In this paper, the various types and assumptions of the ARCH/GARCH models were tried in examining the dynamism of exchange rate and international crude oil prices in Nigeria. And it was observed that the Nigerian foreign exchange rates behaviors did not conform with the assumptions of the ARCH/GARCH models, hence this paper adopted Lag Variables Autoregressive (LVAR) techniques originally developed by Agung and Heij multiplier to examine the dynamic response of the Nigerian foreign exchange rates to crude oil prices. The Heij coefficient was used to calculate the dynamic multipliers while the Engel & Granger two-step technique was used for cointegration analysis.  The results revealed an insignificant dynamic long-term response of the exchange rate to crude oil prices within the periods under review. The coefficient of dynamism was insignificantly in most cases of the sub-periods. The paper equally revealed that the significance of the dynamic multipliers depends greatly on external information about both market indicators which are two-way interactions. Thus, the paper recommends periodic intervention in the foreign exchange market by the monetary authorities to stabilize the market against any shocks in the international crude oil market, since crude oil is the main source of foreign exchange in Nigeria.
