As per the current days of cyber-activities, data security threat in cloud computing have increased, which posses threat in the development of the business. In that field, machine learning based advanced algorithm develop the virtual encrypted environment to protect the data from unauthorized access and hacking.Item To understand the critical measures of enhanced security in cloud computing for creating better data protection(IEEE, 2022-04-28) Lourens, Melanie; Neela, V.; Jambukesh, H.J.; Khan, Huma; Pant, BhaskerToday, the use of cloud computing for better data protection has been increased to a great extent. One of the essential reasons for using cloud computing as a means of data protection is that users can easily access relevant data with the proper security protocols. However, various sectors such as healthcare, finance, automotive, education, manufacturing, etc. have experienced a lot of challenges regarding large and confidential data protection in the past few decades. With the advent of Cloud-computing in recent times, all the issues related to data security and information protection have been easier than before. Researchers have conducted an effective quantitative data collection approach by performing primary analysis through surveys. With a probability sampling technique, researchers have asked around 60 participants from different industrial fields about their opinions regarding the research topic. As per research findings around 60% of people have supported that cloud computing is essential for maximizing data protection. Around 30% people agreed with the 24 times 7 information monitoring and data encryption challenges can be solved with cloud computing. On the other hand, around 10% of participants have placed their positive opinion over the error reduction in data protection by using cloud computing. Researchers in this particular research paper are going to explain the importance of using cloud computing as a data security tool. In order to create better data protection systems across various industrial departments, cloud computing can be used in the future research as well.Item Career development for female academics in Australian and South African universities: an integrative review(Beykent University, 2022-02-15) Kanyumba, Blessing; Lourens, MelanieSouth African and Australian higher education sector is facing challenges of fewer females in leadership positions despite policies in place in both countries. The main purpose of this integrative literature was to analyse and compare journal articles related to career development for female academics in South African and Australian higher education institutions to ascertain the challenges faced by women in both countries. South Africa and Australia was chosen for this study due to the differences in cultural background and legislation. Females are still underrepresented in the leadership positions both in Australia and South Africa, hence this study investigated the reasons and provided recommendations to improve female academics representation in higher education institutions. A literature review of 15 research papers and journals articles published from 2010-2020 was conducted. The key words “career development for female academics” were searched in three databases namely, Google Scholar, Ebsco-host and Emerald. The results from the literature showed that female career development in Australia is moving at a faster pace than in South Africa. The results also show that in both countries glass ceiling and limited female representation in leadership positions is rife in both countries. Female only career development programmes are essential to promote female development in higher education. As this study is focusing on two different countries in different continents, both countries have a lot to learn from each other in terms of policy implementations to enhance female career development. This article provides an analysis of the trends of female career development in South Africa and Australia. Therefore, from the existing literature for a period of 10 years, a conceptual career development model was developed.Item Talent retention strategies for female academics in the higher education sector: a Sub-Saharan Africa context(Beykent University, 2021-11-01) Kanyumba, Blessing; Lourens, MelanieThis study aimed at identifying talent retention strategies for female academics in the higher education sector, paying particular attention to the Sub-Saharan context. Higher education institutions rely on the knowledge, abilities and skills of their academics in order to keep abreast of the changing nature of higher education globally. These institutions of higher learning are required to be competitive and achieve their strategic goals in order to remain relevant in the sector. Studies have shown that female academics are leaving the higher education sector for the private sector for numerous reasons, including better salaries and further development. Additionally, some female academics are emigrating to European countries in search of greener pastures. Therefore, higher education institutions have to ensure that talent retention strategies are implemented to retain female academics, as well as to facilitate their progress to top leadership positions. The study utilized four crucial retention strategies identified in Kenya by Mutiria, Rukangu and Kubaison in 2015. These retention strategies include compensation and benefits, formal succession planning, training and development and career development opportunities. A quantitative research design was adopted for this study, whereby online questionnaires were completed by 112 female academics at a Sub-Saharan university. The data were analyzed using the Statistical package for the Social Sciences (SPSS) version 27 for Windows. The results revealed a significant relationship between the four identified strategies and retention. Thus, institutions of higher learning should effectively implement these strategies in order to retain talented female academics, considering the dynamics in the sector.Item An interdisciplinary approach to address environmental issues: effects of knowledge, attitudes, perception and gender differences(Review of International Geographical Education Online, 2021-11-15) Khan, Samira; Lourens, Melanie; Antriyandarti, Ernoiz; Patra, Bikash; Purohit, Tanushri; Sharma, SapnaIn the research, it has been evaluated that the interdisciplinary approach has led to a rise in the system of education as well as providing holistic training towards the development of society. The rise of AI services has played a significant role in the development of an interdisciplinary approach in Asian countries. However, compared with the European countries, the knowledge, perception, as well as gender differences, have heightened in the Asian countries. The paper has significantly shown the challenges faced in an interdisciplinary approach too where team conflicts and lack of resources have been the main causes respectively. A survey has been conducted with 31 participants. According to survey only 3.2 % of the research participants have agreed that gaining knowledge regarding the environment creates a positive impact on environmental issues. Hence it is able to state that environmental issues in different areas of India, South Africa, and Asia are related to lack of knowledge, attitude, and misperceptions of the people living in these areas. However, it is not associated with gender differences.Item Reflections on the impact of talent management on employee performance: perspectives from Zimbabwe(Advanced Scientific Research, 2020-09-01) Mahlahla, Linah; Lourens, Melanie; Oparinde, KunleThis paper investigates the impact of talent management on employee performance at the Masvingo City Council in Zimbabwe.
