Performance Enhancements for Air-based Networks
Authors: Khalil Muhammad 
Published: July 2022

<p>Power allocation is essential to maximise network throughput and minimise energy consumption and bit error rate performance. Thus, a new power allocation scheme for enhancing the performance of the air-based network, named Unmanned Aerial Vehicle (UAV) networks, is presented in this paper. The proposed power allocation allows the total power to be distributed optimally among the UAV network's nodes, including source relay and destination nodes. Then, energy consumption, transmission delay, and bit error rate in UAV networks are simultaneously enhanced. The typical UAV comprises three parts: remotely controllable flight platform (fixed wing or rotary wing), transmitter and receiver wireless nodes. In the proposed UAV networks, a wireless relay is fitted with a flight platform to extend network coverage and increase transmission throughput. The downside of mobile flight communication is the delay in data transmission caused by the UAV's movement. A consequence of this delay is increased total energy consumption, causing further degradation in bit error rate performance, especially at high <em>SNR</em> levels. Fortunately, delay and energy consumption can be traded off to improve communication performance in wireless communication. The proposed power allocation in this paper is achieved using the Scalarization optimisation method, which enables the best trade-off between energy consumption and data transmission delay and enhances the bit error rate. </p>
A Probabilistic Framework for Controlling Quantum Systems
Authors: Herzallah Randa , Belfakir Abdessamad 
Published: July 2022

<p>A new control method that considers all sources of uncertainty and noises that might affect the time evolutions of quantum physical systems is introduced. Under the proposed approach, the dynamics of quantum systems are characterised by probability density functions (pdfs), thus providing a complete description of their time evolution. Using this probabilistic description, the proposed method suggests the minimisation of the distance between the actual pdf that describes the joint distribution of the time evolution of the quantum system and the external electric field, and the desired pdf that describes the system target outcome. We start by providing the control solution for quantum systems that are characterised by arbitrary pdfs. The obtained solution is then applied to quantum physical systems characterised by Gaussian pdfs and the form of the optimised controller is elaborated. Finally, the proposed approach is demonstrated on a real molecular system and two spin systems showing the effectiveness and simplicity of the method.</p>
Rejection-free Monte Carlo simulation of QUBO and Lechner–Hauke–Zoller optimization problems
Authors: Nambu Yoshihiro 
Published: July 2022

<p> In this study, we implemented a rejection-free Monte Carlo (RFMC) algorithm, which is a kernel of rejection-free SA (RFSA). We showed its validity and advantage in obtaining globally optimal solution for quadratic unconstrained binary optimization (QUBO) and spin-glass problem embedded in the Lechner–Hauke–Zoller (LHZ) architecture. Landscapes of success probabilities of finding the globally optimal solution as well as feasible solutions were evaluated as a function of a set of hyper-parameters used to characterize the weights of cost and penalty functions. We demonstrated that the efficiency of RFMC was greatly enhanced compared to that of standard MC. Furthermore, we found that the landscapes for QUBO and those for LHZ problem show considerably different views. When we focus on a specific class of problems, the smaller the problem size, the more scattered is the success probability. We also show that the success probabilities can be further improved by avoiding inefficiencies due to cycling of state transitions using short-term memory mechanisms. We suggest a reasonable strategy to tune hyper-parameters and find the correct global solution using RFSA. </p>

Published: July 2022

<p>Network science tries to shed light into the complex relationships among entities of a system. For instance, biological networks represent relations between macro molecules such as genes, proteins or other small chemicals. Often potential links are guessed computationally due to expensive nature of wet lab experiments. Conventional link prediction techniques consider local network wiring structure, which may not able to infer true relationships. The recent approaches of graph embedding (or representation learning) aims to capture the complete network structure that may be utilized for link prediction. </p>
<p>In this work, we assess the performance of ten (10) state-of-the-art embedding techniques for their effectiveness of link prediction in homogeneous and heterogeneous biological networks. Majority of the graph embedding methods, in its original form, not in a position to predict links. We use the latent representation of the network produce by the embedding methods and recreate the network using various similarity and kernal functions. We evaluate nine (09) such functions in combination with candidate embedding methods. We even compare the performance of five (05) traditional, local structure based link prediction methods to show the superiority. </p>
<p>Experimental results clearly reveal that Graph Neural Network (GNN) and Attention based encoders with dot product based decoder are the best performers in predicting missing links for both homogeneous and heterogeneous biological network. </p>

EFL Lecturers’ Challenges and Suggestions in the Online Teaching
Authors: Zuhriyah Mukminatus 
Published: July 2022

Online EFL teaching and learning in universities has been conducted for two years during the COVID-19 pandemic. However, the EFL lecturers’ challenges in small private universities in Indonesia are still scarcely investigated. Therefore, this research was conducted with the purpose to describe the Indonesian EFL lecturers’ challenges in their online teaching in the small private universities where they teach English. This was a qualitative research which used online semi-structured interview to six EFL lecturers from six different private universities in East Java to collect the data. Meanwhile, those six private universities did not have the official online platform for online teaching yet. The theory of Miles, Huberman, and Saldana was used to analyze the data. The result was that they faced some challenges in their online EFL teaching related to their students’ presence, the bad internet connection, the unconducive home condition, and the very slow students’ responses. Besides, they suggested to the universities to provide the official online learning platform which is completed with the places for storing their teaching administration archives. Hopefully, these research results can be the consideration for the university policy makers when deciding the guidelines of the online teaching and learning in the universities.

Published: July 2022

The goal of this research is to determine the role of error analysis in teaching English as a foreign language, particularly English Structure. Error analysis can provide information on a student's progress in learning a target language, which is then used to improve the teaching process so that they could still properly use the language. The method used is qualitative and descriptive research design. This research focuses on students of Politeknik Negeri Sriwijaya. Error analysis is essential for teachers to improve the quality of teaching. By doing so, the teacher owns information to improve the methodology including syllabus, teaching material and teaching techniques. The findings are four main stages of error analysis simplified in this study. They are detecting, locating the errors, describing the errors, and classifying the errors. First stage is done by gathering suspected errors; meanwhile works with unwanted errors are rejected or put aside. Then, locating the errors found on students' works were done by identifying them without considering types of the errors. Next step is describing errors where the errors are labeled based on the linguistic category. Final stage is error classification involving classification and counting errors. Each stage gives detailed information of students’ performance which is beneficial for the teachers to improve the quality of teaching including the material and how to deliver.

Authors: Adewumi Samson Adeoluwa 
Published: July 2022

The increasing pressures on the South African government to re-strategize its employment equity policy and ensure people of different races and gender are appropriately represented in employment opportunities are still without barriers. This study interrogates the bridges and barriers to the realisation of employment equity in the eThekwini municipality of South Africa. Remarking on the discourse of employment equity, sparse research attention has been given to the bridges and barriers of employment equity, specifically in the context of the eThekwini municipality of South Africa. To address this gap, the study assesses employment equity programmes that propel employment equity and the challenges constricting the realisation of employment equity in the eThekwini municipality. A total of 15 senior managers were purposively recruited and the semi-structured interview type employed to elicit qualitative data. The data were analysed for the identification of themes with the NVivo (v.12) qualitative software and the various themes analysed with the content qualitative analytical tool. Inclusive initiatives, sufficient budget and women empowerment were shown as important employment equity programmes employed in the municipality. Difficulty in recruiting and retaining scare skills, lack of clarity and commitment to employment equity policy and political leadership and corruption were revealed as constraints to employment equity targets. The study concludes on the need for a more proactive effort on the part of the South African Department of Labour in monitoring and evaluating compliance to employment equity targets with commitment to scarce skills identification and continuous awareness to encourage more women and designated groups into the employment equity folds.

Authors: Nordin Nadhirah , Samsuddin Nur Amani Aisyah , Embong Rahimah , Ahmad Azlin Alisa , Usop Rossidi , Ismail Siti Khatijah , Ismail Suraya 
Published: July 2022

This study aims to develop a business model based on Islamic economic thoughts pioneered by Muslim thinkers such as Abu Yusuf, al-Syaibani, Abu Ubayd, al-Mawardi, al-Ghazali, Ibn Taimiyah, and Ibn Khaldun. They existed from the early period of Islam until 1446. An absence of consensus on the definition of a business model that is universally accepted has led to the reassessment of the current business model towards pro-business and encouraged by profit margins. A holistic and comprehensive business model influences a business's enhanced performance. Hence, in reality, the survival rate of businesses, mainly businesses run by Muslims, is at a low ebb, although Islam has provided guidelines for all life activities, including business strategies. Hence, further studies should be conducted to seek solutions to overcome the resilience of Muslim businesses by referring to the thoughts of Islamic economic scholars. However, the scholarly thoughts were not organised as a scientific discipline, which eventually led to a decline in the Islamic economy, and consequently, humans began to follow the conventional economy. Data were collected through the document analysis and Focus Group Discussion (FGD) methods involving agency representatives, entrepreneurs, and academicians in the business field. It was then analysed using the content analysis method. Findings indicate that the business model comprised four components, namely production, business transactions, marketing, and the government's role, which was based on Islamic creed (aqidah), Islamic law (shariah), and Islamic morality and manners (akhlaq), acts as a catalyst for a successful business venture. This study has a significant impact and offers a new solution for overcoming and substantiating society's economic growth and development by making business a mechanism for empowering the Islamic economy.

The Changing Approach of North Korea Towards America, South Korea and the Prospects of Inter-Korean Relations
Authors: Dang Bui Hai , Hiep Tran Xuan , Tuan Luc Minh , Thao Nguyen Thi Phuong , Thang Nguyen Van 
Published: July 2022

North Korea's international integration strategy and the normalizing process of inter-Korean ties forced North Korea to modify its attitude to the US and South Korea. Observing inter-Korean relations in recent years, we do acknowledge the adjustments of both sides to each other and in relations with the US; in which, the most notable is the adjustment in North Korea's approach to South Korea and to the US. In relations with the US, there are significant shifts in North Korea’s approach from the "maximum cordiality" approach to a parallel one: constructing "a new peace" in accompaniment with "a new threat". The US has been such an important factor in inter-Korean relations which have been affected by US relations with the two sides of Korea peninsula. With South Korea, North Korea has built a new type of relationship with four matching objectives: jointly reform personnel in the direction of respecting the spirit of reconciliation between the two regions; jointly promote economic self-reliance alongside the military policies to diminish dependence on allies of both sides; establish inter-Korean trade activities unaffected by international sanctions; and support mutual communication to gradually change negative public opinion trends about North Korea in the region and around the world. This paper is to focus on analyzing and explaining the changes in North Korea's approach to the US as well as to South Korea after the 2nd U.S-North Korea Summit in 2019 failed. It will conclude by making predictions about the prospects of inter-Korean relations in the coming years.

Assessment of the Impact of COVID-19 Pandemic on Economic Performance: DSGE and Probit Investigations
Authors: Alofaysan Hind , Mabrouk Fatma , Bousrih Jihan 
Published: July 2022

The paper proposes an innovative microeconomic analysis of the effects of COVID-19 on the economic performance by relying on two different approaches. Firstly, we consider a theoretical investigation by implementing a DSGE model where we propose a negative health shock on the supply part of the economy. The second approach is based on empirical investigation via Ordered Probit Regressions using the Saudi Labour Force Survey where we focus on time and regional effects by comparing 2019 and 2020 indicators. On one side, our findings reveal that health shock impacts household health spending. An affected household by the COVID-19 will see its resources decreasing due to the indirect costs of the pandemic related to the loss in productivity and labour supply. It is much more than that the COVID-19 pandemic hurts working hours and earnings. On the other side, the results show that individuals with higher degree of schooling and high skills seem to be not affected during the pandemic. Additionally, the effect of the current health crisis is more noticeable in Riyadh, Southern and Western region and is more intensive in the private sector and for non-Saudi workers.

The Association between Accounting Conservatism and Cash Holding, Dividends and Leverage
Authors: Atwa Rawan , Bsoul Ruba , Kharabsheh Buthiena , Azzam Mohammad 
Published: July 2022

This paper examines the effect of accounting conservatism on several financial decisions in Jordan. In particular, it aims to expose the effect of accounting conservatism on cash holdings, dividends distributions, and leverage for a sample of 83 Jordanian industrial and service firms listed on the Amman Stock Exchange (ASE) for the period 2015-2019. The feasible generalised least squares (FGLS) regression technique is used to test the association between accounting conservatism and financial decisions. The findings of this paper reveal a negative and significant relationship between accounting conservatism and cash holding. However, positive but insignificant relationships are reported between accounting conservatism and both dividends distributions and leverage. These findings have important implications for investors, corporate managers, and policymakers. The study recommends that future research use different measures of leverage, such as debt-to-equity ratio and long-term debt to equity ratio, in order to compare the results of different measuring instruments. It also recommends incorporating other measures of conservatism, such as market to book ratio and timeliness asymmetric measure.

Authors: Arnilla Arvin Kim 
Published: July 2022

This study aimed to evaluate the virtual synchronous continuing professional development (CPD) through webinars organized by a rural university in a developing country. Using quantitative and qualitative methods, the results highlighted the resourcefulness of the organizers to resolve technological and financial limitations prevalent across the preparation and implementation stages. The desire to participate in the narrative of CPD during the COVID-19 pandemic resorted to researching, testing, and utilizing free online platforms to deliver knowledge and skills to a wider audience. Screen sharing and audio-video streaming through social media were enough to facilitate the webinars. The result of the evaluation revealed that the webinars were appreciated by the participants and contributed to the increase in their knowledge of the topics presented. The CPD project also confirms the disparity in resources confronting institutions in developing countries like low internet bandwidth, outmoded internet cable wires, and unreliable supply of electricity. Management systems may be revisited to keep up with the pace in instruction and extension services in the light of changing requirements of the new normal.

Published: July 2022

This study aimed to identifying the impact of accounting conservatism on financial performance in services companies listed on Amman Stock Exchange, where the accounting conservatism was measured through the model of (Gvoly & Hyans, 2000), an approach that based on accruals, while the financial performance was measured through the return on equity (ROE), and earnings per share (EPS). And in order to achieve the objectives of the study, the descriptive and analytical approach was adopted, where the study was conducted on a sample of (23) service companies listed on Amman Stock Exchange during the period from 2015 to 2019. Also, in respect of analyzing the study data and test its hypotheses, the statistical analysis program (SPSS) was utilized, and simple regression equation was relied on in testing the hypotheses. Whereas, the major findings of the study are as follows: There is no statistically significant impact of the accounting conservatism on the financial performance with its indicators (rate of return on equity, and profit per share) in the services companies listed on Amman Stock Exchange. Meanwhile, the study recommended the necessity of urging the researched and listed services companies’ management on Amman Stock Exchange (especially those characterized by low accounting conservatism) to apply the principles and standards of accounting conservatism, due to the importance of these procedures on the quality of the financial reports and consequently the profits therein.
