ItemBlockchain and Edge Computing Integration Boosts Scalability and Reduces Latency(Institute of Electrical and Electronics Engineers Inc., 2023) Mahfuri, Mahmoud; Alnawaiseh, Ahmad Enad; Asad, Umber; Yousif, Muhammad; Aslam, Shoukat; Chabani, Zakariya; Fiaz, Muhammad ItemCOVID-19 and the new forms of employment relationship: implications and insights for human resource development(Emerald Group Holdings Ltd., 2021) Hamouche, Salima; Chabani, ZakariyaPurpose: The labor market has witnessed the increase of the new forms of employment relationship (freelancers, contingent workers, and gig workers) due to the COVID-19 outbreak, generating new workforce patterns that represent a significant challenge for human resource development (HRD) professionals in organizations. Studies that have addressed these new forms of employment relationship and HRD during this pandemic are sparse. This paper aims to broaden the scope of HRD research by exploring the implications of these new forms of employment relationship for HRD in the time of COVID-19. It also provides insights for HRD professionals as well as governments into how to address this challenge. Design/methodology/approach: This paper is a viewpoint that addresses the new workforce patterns generated by the COVID-19 pandemic and their implications for HRD at the organizational, individual and national levels. Findings: COVID-19 sheds light on the importance of atypical workers who can create a competitive advantage for organizations, ensure their continuity and significantly benefit national and societal well-being in times of health crisis. However, these atypical workers are often overlooked when it comes to training and development. Whence the importance, for HRD professionals and governments, to address their situation and to integrate them into organizational and national HRD plans and programs, by going beyond traditional models of HRD which focus mainly on standard employees. Originality/value: This paper examines a relatively unexplored topic. Besides examining the implications of the new forms of employment relationship, for HRD, it provides insights for HRD professionals and governments into how to address the challenges related to these new forms of employment relationship. © 2021, Emerald Publishing Limited. ItemE-Supply Chain Issues in Internet of Medical Things(Institute of Electrical and Electronics Engineers Inc., 2022) Ghazal, Taher M.; Al-Dmour, Nidal A.; Mohamed, Tamer; Chabani, Zakariya; Harguem, Saida; Noamas, Samar; Almaazmi, Noura ItemThe Impact of Entrepreneurial Culture on Economy Competitiveness in the Arab Region(Allied Business Academies, 2021) Chabani, ZakariyaThe main emphasis of this study was assessing to what scope entrepreneurial culture among Arab counties affects the overall regional competitiveness of the MENA region. Data from each country were first solely analyzed then grouped by its subsequent trading blocks. An average assertion of the combined data was granted in the bid of assessing any entrepreneurial cultures. The entrepreneurial culture analysis of the countries and regions within the study were based on the time span through which the referenced entrepreneurial activity has been dominant and the education level of stakeholder. Most Arab countries have the same entrepreneurial structure and economic competitiveness despite various external factors affecting them. The results also revealed that the relationship between each country's internal economic competitiveness and the overall posture of the Arab region is positive. Besides, the relationship between dominant entrepreneurial cultures and the overall economic posture of the Arab region is also statistically confirmed. Much of the past studies failed to include and relate the external factors like the growing entrepreneurial cultures among states and regions. Basing conclusions on one region while others could convey disparities was regraded rather impractical. As such, to affirm the validity of conclusions; The relationship between the Economic Community of West Africa (ECOWAS) and North African countries from one part, and the Association of Southern Asian Nations (ASEAN) and the other Arab countries from another hand, had to be taken into consideration. © 2021.

ItemInformation Systems Solutions for the Database Problems(Springer Science and Business Media Deutschland GmbH, 2023) Al-Dmour, Nidal A.; Ali, Liaqat; Salahat, Mohammed; Alzoubi, Haitham M.; Alshurideh, Muhammad; Chabani, Zakariya ItemIs Blockchain Technology Applicable in Small and Medium-Sized Enterprises?(Springer Science and Business Media Deutschland GmbH, 2021) Chabani, Zakariya; Hamouche, Salima; Said, RaedThe purpose of this research is to investigate the applicability of blockchain technology in Small and Medium Enterprises (SMEs). We have examined the advantages and the disadvantages of the use of this emerging technology in SMEs, based on the existing literature on this research topic. Applying blockchain in SMEs has many advantages: promoting transparency in the organization, facilitating market analysis for better decision-making, eliminating reconciliation costs, and making auditing easier. However, it has some disadvantages, such as; the reshuffling of job positions and the absence of clarity related to the industrial standards. Therefore, we proposed some recommendations in order to adopt this technology successfully. Firstly, the SMEs should design the distributed ledger technology (DLT) in a way to have flexible governance and regulations so that it will be easily upgradeable; additionally, it is essential that the adopted DLT design by an SME can be migrated to a different blockchain whenever the need arises. Also, DLT designers should ensure that measures are taken to limit the collection of personal information. The SMEs should also establish trust and interoperability to realize the full benefits of DLT. Finally, SMEs should invest in research that will ensure more knowledge about the perfection of blockchain technology. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG. ItemMachine Learning Based Prediction of Stock Exchange on NASDAQ 100: A Twitter Mining Approach(Institute of Electrical and Electronics Engineers Inc., 2022) Harguem, Saida; Chabani, Zakariya; Noaman, Samar; Amjad, Muhammad; Alvi, Muhammad Bux; Asif, Muhammad; Mehmood, Muhammad Hassaan; Al-Kassem, Amer Hani ItemMeasurement of antioxidant capacity of meat and meat products: Methods and applications(MDPI AG, 2021-07-01) Echegaray, Noemí; Pateiro, Mirian; Munekata, Paulo E. S.; Lorenzo, José M.; Chabani, Zakariya; Farag, Mohamed A.; Domínguez, RubénAt present, a wide variety of analytical methods is available to measure antioxidant capacity. However, this great diversity is not reflected in the analysis of meat and meat products, as there are a limited number of studies on determining this parameter in this complex food matrix. Despite this, and due to the interest in antioxidants that prevent oxidation reactions, the identification of antioxidants in meat and meat products is of special importance to the meat industry. For this reason, this review compiled the main antioxidant capacity assays employed in meat and meat products, to date, describing their foundations, and showing both their advantages and limitations. This review also looked at the different applications of antioxidant properties in meat and meat products. In this sense, the suitability of using these methodologies has been demonstrated in different investigations. © 2021 by the authors.Licensee MDPI, Basel, Switzerland. ItemThe Role of Blockchain Technology in Enhancing Security Management in the Supply Chain(Springer Science and Business Media Deutschland GmbH, 2022) Chabani, Zakariya; Chabani, WidadThis study aims to analyze the role of blockchain technology in enhancing security management in supply-chain management. The information was collected from various sources, organized into two sets of variables for privacy and security cases, and analyzed using EViews software. Data analysis was done by performing three tests: correlation, cross-correlation, and Granger’s causality test. The findings revealed a correlation between the use of blockchain technology in the supply chain and security and privacy complaints among organizations and individuals. It also revealed a unidirectional causality between security concerns and the degree of application of blockchain technology in the supply chain. The paper represents one of the very few empirical studies that have been done about the subject. The paper is expected to change the public’s understanding of blockchain technology related to security and privacy, two of the essential aspects of supply-chain management in contemporary corporate society. The main limitation of this study comes in the form of a lack of readily available data. Several data sources had to be used, including existing literature and statistics from reputed sites like Statista, to ensure sufficient information was collected to facilitate the study’s key objectives successfully. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG. ItemTHE CHALLENGES FACING PUBLIC ORGANIZATIONS TO IMPLEMENT HUMAN RESOURCES INFORMATION SYSTEMS: A CASE STUDY OF ALGERIA(Allied Business Academies, 2020-09) Chabani, ZakariyaThe purpose of this research is to identify the managerial purposes, benefits and challenges of HRIS implementation within public organizations to better understand how such technologies affect the capacity of the HR department to conduct effective and efficient work. This research is part of a constructivist epistemological approach. To achieve the main goal of the study, data were collected primarily via a semi-directive interview conducted at one of the biggest public companies in Algeria in 2018. In addition to the questionnaire, some of the organization's documents were used in combination with observations that allowed the researcher to confirm some of the data collected from the questionnaire. The management of the case study organization well understands the importance of HRISs. Thus, the management decided to implement the system. Although the implementation was successful, the management faced some problems, such as resistance to change from users in various divisions. Therefore, we can conclude that HRISs may contribute to enhancing the performance of HR departments and improving management processes. However, to ensure performance, the implementation must take place under the best possible conditions. Otherwise, the HRIS is no longer be an advantage but rather a significant cost. This is one of the few studies investigating the role of HRIS implementation in improving the HR department and management processes within a public organization. Due to the very specific characteristics of such organizations, which vary with regard to flexibility, bureaucratic attitude, resistance to change, etc., implementing HRISs can be very challenging. © 2020.
