This study aims to address the prevailing skepticism that conventional leadership models are not effective in the Middle East. With the same logic, selecting leaders is a confusing task in the Middle East due to the haphazardness surrounding this task and the lack of clarity of appropriate selection criteria. This study employs samples of leadership theories and frameworks that were scrutinized to classify specific leadership dimensions. The triangular model stemmed from the previous studies that addressed Leadership in general and the Leadership model for the Middle East. With the use of the literature review methodologies and historical analysis, the leadership model's description will be demonstrated. The results revealed that there are various dimensions of Leadership, especially concerning the Middle East's organizational environment. The findings of this study suggested a new model which assists in clarifying the issue by setting a group of 10 personality traits with eight behavioral skills and social status. Implications of this study enable making Leadership easier in practice. Furthermore, this will enable recognition of Leadership according to specific criteria, which will help make greater equality and empowerment at all levels of the system. This research localizes Leadership and paves the way to automate leaders' selection process with a guarantee of fairness among candidates.

We investigate the channel allocation problem in an ultra-dense device-to-device (D2D) enabled cellular network in underlaying mode where multiple D2D users are forced to share the same channel. Two kinds of low complexity solutions, which just require partial channel state information (CSI) exchange, are devised to resolve the combinatorial optimization problem with the quality of service (QoS) guaranteeing. We begin by sorting the cellular users equipment (CUEs) links in sequence in a matric of interference tolerance for ensuring the SINR requirement. Moreover, the interference quota of CUEs is regarded as one kind of communication resource. Multiple D2D candidates compete for the interference quota to establish spectrum sharing links. Then base station calculates the occupation of interference quota by D2D users with partial CSI such as the interference channel gain of D2D users and the channel gain of D2D themselves, and carries out the channel allocation by setting different access priorities distribution. In this paper, we proposed two novel fast matching algorithms utilize partial information rather than global CSI exchanging, which reduce the computation complexity. Numerical results reveal that, our proposed algorithms achieve outstanding performance than the contrast algorithms including Hungarian algorithm in terms of throughput, fairness and access rate. Specifically, the performance of our proposed channel allocation algorithm is more superior in ultra-dense D2D scenarios.

State-Owned Enterprises (SOEs) are business entities that are owned mainly by the state. Good financial governance (GFG) is as important for SOEs as for the private sector companies. Prudence and GFG can affect the value of the company. This research aims to test the impact of macroeconomics, investment decisions, and financing decisions on prudence, Corporate Social Responsibility Disclosure (CSRD), dividend policy, and company value of SOEs registered on the IDX from 2014-2019. GFG and financing decisions are moderating variables. The population in this study is 16 SOEs listed on the Indonesia Stock Exchange from 2014-2019. The research method is quantitative and uses Partial Least Squares (PLS), which is an approach to Structural Equation Models (SEM) that allows researchers to analyze the relationships simultaneously. The results showed that macroeconomic factors, investment decisions, financing decisions, and prudence directly affect the company's value. However, CSRD and dividend policy directly do not affect the company's value. Prudence can mediate the influence of financing decisions on company value. GFG moderates the relationship between prudence and company value. Thus, GFG is key to producing compliant regulatory reports and disclosures. GFG aims at facilitating effective monitoring and efficient control of the business. Its essence lies in fairness and transparency in operations and enhanced disclosures for protecting the interest of different stakeholders.

This paper aims to provide a review concept regarding the relationship between corporate governance and corporate sustainability in Indonesia. This paper examines the mechanisms and guidelines for implementing good corporate governance. This research used the literature review method and explores some effective corporate governance principles such as transparency, accountability, responsibility, independence, fairness, and equality to achieve business sustainability in Indonesia's setting. The results show that good corporate governance regulation in Indonesia has been improved, but the enforcement is still needed to be optimized because good corporate governance will positively impact corporate sustainability. Thus, sustainability requires more corporate innovation because sustainability is about how a company can create profits and value-added to society through corporate social responsibility (CSR) programs and how the company can contribute to the preservation of nature and the environment. In Indonesia, the board of directors, the board of commissioners, and the audit committees are positively related to CSR disclosure. Thus, leadership and management efforts are crucial. However, to comprehensively support the synergy of implementing good corporate governance, we need the role of the state, the business community, and society. This study provides important insights into the implementation of good corporate governance in achieving corporate sustainability in Indonesia.

In this paper, we propose a linear programming model of supply planning process for the supply chain collaboration strategy of a company. The amount of its supplying quantity relies on outsourcing suppliers heavily. Conversely, the revenues of those suppliers are highly dependent on the supplying quota from the supply network planning of the company. In order to keep the supply stable through collaboration, the company builds such a policy to guarantee the fairness on revenue between the supplies. For this, the supply network plan should keep the capacity utilization ratio even for all the suppliers. But the production capacities are different and the distribution of molds is disproportional through suppliers, so the supply network plan is not easily established with simple arithmetic processes. Therefore, we developed the linear programming model with those target function and constraints minimizing the costs for holding inventory and penalty of delayed delivery, simultaneously guaranteeing the even capacity utilization through suppliers. The proposed model has been applied to real case and the evaluation for the planning result from the model would be followed in order to make sure that our model guarantee on extracting the supply network plan subordinated to the policy. Also we mention about further studies for improvement of the model.

For energy-efficiency in Wireless Sensor Networks (WSNs), when a sensor node detects events, the sensing period for collecting the detailed information is likely to be short. The lifetime of WSNs decreases because communication modules are used excessively on a specific sensor node. To solve this problem, the TARP decentralized network packets to neighbor nodes. It considered the average data transmission rate as well as the data distribution. However, since the existing scheme did not consider the energy consumption of a node in WSNs, its network lifetime is reduced. In this paper, we propose an energy awareness congestion control scheme based on genetic algorithms in WSNs. The proposed scheme considers the remaining amount of energy and the transmission rate on a single node in fitness evaluation. Since the proposed scheme performs an efficient congestion control, it extends the network lifetime. In order to show the superiority of the proposed scheme, we compare it with the existing scheme through performance evaluation. It is shown that the proposed scheme enhances the data fairness and improves the network lifetime by about 27% on average over the existing scheme.

Purpose - This study examines the relationship between organizational justice and employee job satisfaction and the extent of its moderation by perceived alternative job opportunities. Research design, data, and methodology - This is a cross-sectional study utilizing survey questionnaire data from 220 bank employees, which included scales measuring organizational justice, job satisfaction, and perceived alternative job opportunities. Results - The data is analyzed using correlation and hierarchical regression. Results demonstrated that organizational justice has a direct positive impact on employee job satisfaction further, distributive justice explains more variance in job satisfaction, followed by procedural justice and interactive justice. Perceived alternative job opportunities moderate the relationship between organizational justice and job satisfaction. Conclusions - Generally, organizational justice increases bank employees' job satisfaction; however, when they perceived more job opportunities, their job dissatisfaction increased notwithstanding fairness. Therefore, perceived job opportunities moderate the relationship between organizational justice and job satisfaction. Retaining skilled employees has become difficult, especially when there is market demand for skilled workers. Human resource (HR) managers should consider market situations before formulating policies; otherwise, they may lose the competitive advantage of skilled employees and workers.

This study aims to explore the relationship between organizational justice and social loafing of organizations in Ho Chi Minh City through quantitative analysis from the survey data for the 228 employees are working at the Organizations in Ho Chi Minh City. The instrument of collecting data was a questionnaire. The collected data were analyzed using SPSS version 22 and employing exploratory factor analysis (EFA), Cronbach's alpha, multiple regression analysis. The results showed that only two factors are Distributive justice and Procedural justice is to have the reverse effect on social loafing of employee. From the results of the study showed, Distributive justice and Procedural justice has the opposite effect of social loafing, which demonstrates that when individuals feel that their work is spent on Perform tasks in a clearly divided and they will receive a worthwhile result in the group when performing the task then the individual's collective indifference to the organization will decrease. And motivate the employee to make more efforts to work and contribute for the organization. In addition, the factor of Procedural justice also has the opposite effect of collective redundancy, which demonstrates that employees are more concerned about fairness in official policies and organizational procedures.

A convergecast is a popular routing scheme in wireless sensor networks (WSNs) in which every sensor node periodically forwards measured data along configured routing paths to a base station (BS). Prolonging lifetimes in energy-limited WSNs is an important issue because the lifetime of a WSN influences on its quality and price. Low-energy adaptive clustering hierarchy (LEACH) was the first attempt at solving this lifetime problem in convergecast WSNs, and it was followed by other solutions including power efficient gathering in sensor information systems (PEGASIS) and power efficient data gathering and aggregation protocol (PEDAP). Our solution-chain routing with even energy consumption (CREEC)-solves this problem by achieving longer average lifetimes using two strategies: i) Maximizing the fairness of energy distribution at every sensor node and ii) running a feedback mechanism that utilizes a preliminary simulation of energy consumption to save energy for depleted Sensor nodes. Simulation results confirm that CREEC outperforms all previous solutions such as LEACH, PEGASIS, PEDAP, and PEDAP-power aware (PA) with respect to the first node death and the average lifetime. CREEC performs very well at all WSN sizes, BS distances and battery capacities with an increased convergecast delay.
