  • The impact of South African culture on the work-life balance of women in
           leadership positions

    • Authors: Naong Matsidiso Nehemia, Naong Mammako Lenkoe
      Pages: 212 - 226
      Abstract: Women are the pillars of every healthy society. Numerous socio-cultural practices, especially patriarchy and religion in African communities deprive women of equality and justice across all sectors of society. However, younger and educated generations seem to adopt a different attitude. This paper explores the impact of South African culture and the work-life balance (WLB) of women in managerial positions since the democracy’s inception. A survey based on elements of three complementary theories: the role of congruity, feminism and cultural dimension theories was used to collect data from 187 women in leadership positions in the Mangaung metropolitan municipality in the Free State province of South Africa giving a 75% return rate. A factor analysis was conducted to determine the loading of items. The reliability of instruments using the Cronbach alpha value was reported at 0.87. Results reveal that 47.1% bemoan cultural tendencies at work. Furthermore, 35.7% opined that the choice between adoption and conceiving children is non-negotiable, despite pressing work demands and 34.3% agreed that culture makes them feel guilty if they give their work preference over their family life. Crafting human resource strategies that advocate for ‘gender equality or sensitivity’ and harmonise the work-life balance of female staff in order to enhance their performance in a sustainable way is long overdue and needs to be prioritized by any South African organizations.

  • Influence of virtual reality on the process of personality socialization:
           A distance model of socialization

    • Authors: Baglan Zhaparova, Natalya Kolyeva, Aigul Akhmuldinova, Fatima Shnaider, Aliya Mambetalina
      Pages: 235 - 241
      Abstract: The purpose of the study is to substantiate the theoretical aspect of the distance model of socialization. The conducted theoretical analysis discloses the relationship between the growing popularity of virtual internet space and the emergence of new online social activities and form social interaction between individuals which proves that the internet has become a dynamic new environment of personality socialization. Based on an analysis of the theoretical provisions of socialization, the authors refine the essence of the concept of the distance socialization model. The paper gives substantiation to the provision that the distance model of socialization creates the conditions for a developing personality to express its social activity in relation to social action, inaction or social deeds through the mechanism of social expression. This distance mechanism is also present in the real social space, yet in the distance model of socialization on the web, it becomes predominantly relevant dominates and leads. The authors suggest that within the distance model of socialization, this mechanism becomes the basis for the construction of an individual’s virtual identity and its online social space as well as a foundation for the expansion of the individual's social experience in the real social space.

  • Environmental-based diseases of students in urban and rural areas, Lampung
           province, Indonesia

    • Authors: Subian Saidi, Netti Herawati, Khoirin Nisa
      Pages: 242 - 249
      Abstract: The aim of this study is to examine environmental-based diseases among students in Lampung Province, Indonesia. A total of 1,000 students from all districts in Lampung Province participated. Subsequently, the student disease distribution was grouped using the ROCK (Robust Clustering Using LinKs) method. The results indicated that many students were in a cluster often exposed to environmental-based diseases (cluster 4). The type of environmental-based disease that mostly affects the students in cluster 4 is skin disease while very few suffer from intestinal worms. The results of this study also demonstrated that students in rural areas suffer more from environmental-based diseases than those who live in urban areas. The majority of students in urban areas suffered from air-sensitive diseases (42%). Cluster 4 was the group of students who suffered from environmental-based diseases. Environmental-based diseases arise or recur due to environmental pollution such as acute respiratory infections (ARIs), diarrhea, intestinal worms, pulmonary tuberculosis and skin diseases. This may be due to the lack of awareness and knowledge of students in rural areas regarding the importance of protecting the environment in order to avoid environmental-based diseases.

  • Influence of technology acquisition, external technology exploitation and
           employee autonomy on the performance of bureaucratic organizations

    • Authors: Isaree Suwannasri
      Pages: 250 - 257
      Abstract: Organizations use technology to prosper in the digital and technological revolutions. The digital and technical revolution has prompted governments to adopt and use technology to provide effective services to citizens. The purpose of this research is to examine how technology acquisition, external technology exploitation, employee autonomy through open innovation and innovation performance affect bureaucratic people’s development. The researcher quantitatively distributed the questionnaire online. Four departments were chosen to collect data from 480 IT-related respondents. For hypothesis testing and correlation, the structural equation model (SEM) was used. The results demonstrated a significant relationship between technology acquisition, open innovation, external technology exploitation, innovation performance, employee autonomy, open innovation and organization performance. The research’s findings revealed that an organization's performance can be practically achieved by obtaining advanced technology, external knowledge and the skills of its personnel through open innovation which can drive innovation performance toward organizational performance. Consequently, it indicates that employees and cutting-edge IT are essential for generating new ideas for open innovation and enhancing an organization's performance. Leaders and employees must understand open innovation to maximize themselves and their organizations’ potential. In addition, the most important practical implication of this research is that implementing advanced technology, innovation and technology management that includes digital literacy can improve the performance of bureaucratic organizations.

  • Factors of educational inclusion to improve learning: Teachers'
           perspectives

    • Authors: Yersi-Luis Huaman-Romani, Iris-Liliana Vasquez-Alburqueque, Fredy Carrasco-Choque, Linda-Katherine Carrillo-De la Cruz, Juan C Orosco Gavilan
      Pages: 258 - 265
      Abstract: In elementary school, inclusive education should be adapted to the needs of students with special abilities in areas such as recreational activities, feedback and methodologies and planning. The objective of the research is to analyze and describe the perspectives of educational inclusion factors among elementary school teachers to improve students’ learning with special abilities. The methodology of the research is descriptive with a quantitative correlational approach in which 823 elementary school teachers participated through a voluntary and anonymous online survey with a measurement instrument that had two dimensions of eight and ten items which were optimal in the different statistical tests as in the analysis of the reliability factors of Cronbach’s alpha (0. 968). The result shows that teachers are willing to improve the curriculum plan, provide specialized attention after training. There is a high perspective to interact with students with special abilities to improve student learning. There are institutional constraints on primary education teachers to improve the learning factors of inclusive education as well as unknown applications or technologies that can help the learning of students with special abilities in primary education. There are non-governmental organizations that seek the welfare of students with special abilities but the results are not very encouraging due to a lack of financial capacity.

  • Entrepreneurial innovation among international students in the UAE:
           Differential role of entrepreneurial education using SEM analysis

    • Authors: Fanar Shwedeh, Ayotunde Adetola Adelaja, Gbemisola Ogbolu, Abdelkarim Kitana, Abdallah Taamneh, Ahmad Aburayya, Said A Salloum
      Pages: 266 - 280
      Abstract: This paper explores the impact of entrepreneurial education among international students studying higher education in the UAE. The authors examine the role of entrepreneurial education as an independent variable and as a moderating variable in the relationship between external factors (measured by the economy, institutions and society) and internal factors (measured by entrepreneurial orientation, entrepreneurial capabilities and achievement) on entrepreneurial innovation. A survey approach was used in which predesigned questionnaires were distributed to the targeted respondents. We employed Structural Equation Modelling (SEM) analysis to analyze the collected data. The result reveals that exposing international students to entrepreneurial education is crucial to their entrepreneurial innovation. We also found the external and internal environments to be crucial factors that predict entrepreneurial innovation among the sample surveyed. Further findings revealed that entrepreneurial education significantly moderates the relationship between the external environment and entrepreneurial innovation whereas the moderating effect of entrepreneurial education on the relationship between the internal environment and entrepreneurial innovation was found to be insignificant. The findings provide valuable insight for not just higher education institutions offering entrepreneurial education courses in the UAE. Nevertheless, for entrepreneurship stakeholders globally understanding how to enhance the significant role of entrepreneurial education on external and internal factors will ensure higher innovativeness among international students in the host country.

  • Teaching performance at private universities in Medan City: Analysis of
           factors affecting university governance

    • Authors: Januri, Azhar Maksum, Iskandar Muda, Rina Br Bukit
      Pages: 281 - 288
      Abstract: The purpose of this research is to find out what factors influence the performance of tertiary institutions in obtaining accreditation. A structural Equation Model (SEM) is used for data analysis. The data processing tool in the buying and selling model in this study uses Partial Least Squares (PLS). The research design is causal research and the variables used are the performance of private universities governance, funding, internal audit, participation in budgeting and risk management. The results of the study show that internal audit has an impact on university governance. Budget participation and risk management have a positive effect on good university governance while financing and internal audit have a negative effect on university performance. Empirical evidence analyzes the effect of risk management on university performance at private universities in Medan City.

  • Problems and responses of schools in the COVID -19 pandemic: The case of
           Mountain Province

    • Authors: Willow F Pangket
      Pages: 289 - 300
      Abstract: This study explored the problems faced by the schools in Mountain Province, Philippines with the implementation of distance education during the pandemic and looked into the schools' good practices to mitigate the problems. 26 schools participated in this study. Analysis of the data gathered highlighted the serious problems in Philippine education. The problems faced by the schools during the pandemic are similar to those faced by developing countries, however, the problems and responses faced by the schools in Mountain Province are specific to their context. The common problems identified during this pandemic are: difficulty in distributing and retrieving modules, unavailability of equipment and gadgets, poor internet access, poor quality of learning materials, the unpreparedness of parents taking on the role of teachers, teachers' lack of training on the modality of learning, lack of technological knowledge, a one-size-fits-all approach to instruction, an inadequate learning management plan for blended learning and the decreased income of private schools. The good practices implemented by the schools to address some of their problems are: home visits, tutorials, Parent-Teacher Association (PTA) involvement, remediation classes, a seminar on stress management and mechanisms for blended learning. There is a need for the school administration to provide learning management plans which should include short and long-term goals and professional learning initiatives like training to improve teachers' technological pedagogical knowledge.

  • Exploring the effects of ventilation and air-conditioned environments, on
           droplet and airborne transmission of SARS-COV-2

    • Authors: Sinan Deeb, Haithem Rehan, Husam Hamameh, Ilona Schwentner, Stephan Wolpert, Sven Becker
      Pages: 301 - 309
      Abstract: To assess the implications of air conditioning and ventilation on droplet and airborne transmission of SARS-COV-2, several scientific research databases were searched and cross-referenced. Then, an analysis was conducted on the findings pertinent to interaction between several environmental variables affected by HVAC systems and their effect on Virus transmission. The results suggest that airflow velocity may interfere with the trajectories of large respiratory droplets and aerosols. Lower relative humidity provided suitable conditions for virus survival whereas higher temperatures increased aerosol formation, but were detrimental to virus survival. Suboptimal temperatures and humidity can compromise pathogen filtration functions in the nose, while proper use of HVAC functions can help preserve them. Transmission of SARS-COV-2 is not affected solely by the virus’s internal properties. Ambient conditions, whether natural or modified by HVAC systems can have a significant effect on the transmissibility and virulence of both the virus and virus-related sickness. The current infection prevention measures, such as social distancing, need to be revised in certain scenarios where natural ventilation or HVAC systems are involved. This will offer, hopefully, higher protection from infections with SARS-COV-2 and similar pathogens.

  • Evaluating the efficiency of stone columns in mitigating liquefaction
           risks and enhancing soil bearing capacity: A case study

    • Authors: Mohamed BZIAZ, Lahcen BAHI, Latifa OUADIF, Anas BAHI, Hamou MANSOURI
      Pages: 310 - 321
      Abstract: Several processes allow the improvement of soils such as vibrocompaction, stony columns, static horizontal compaction etc. These processes reduce the risk of liquefaction potential and making it possible to build on this type of soil when the space restriction require it. Stone columns are a recognized method of soil improvement, which consists of creating large diameter columns using special vibrators with granular filling materials introduced into the ground. The objective of this work is to evaluate the effectiveness of stone columns, made in a seismic zone containing liquefiable materials, with regards to the reduction of the risk of liquefaction and the improvement of the bearing capacity of the soil. The approach followed is the exploitation of geotechnical investigation tests (CPT Cone Penetration Test), (SPT: Cone Penetration Test, (pressuremeter tests), carried out before and after soil treatment. This study showed that the network of gravelled columns produces an enhanced soil improvement effect by improving the modulus of elasticity of the soil and reducing settlement and the risk of liquefaction after treatment. The process allows for the improvement of the geotechnical characteristics of its soils, making it possible to build infrastructure and development projects in the area.

  • UNESCO practices under the SDG4 and COVID-19 response framework: Topic
           modeling from 2003 to 2021

    • Authors: Kyung Hee Park, Qi Liu, He Li
      Pages: 322 - 329
      Abstract: This study focused on the impacts of COVID-19 on SDG4 to resolve inequality through education and explored UNESCO's educational practices. We used text mining to analyze strategic and crisis-related reports published by UNESCO from 2003 to 2021 and LDA topic modeling analysis was used to determine their latent contexts. Two topics related to education strategies were 'sustainable development' and 'system and organization'. According to the themes, non-formal, formal and informal learning and skills and TVET topics were derived for lifelong learning, school and teacher, emergency and peace, policy and framework in the theme of crisis and conflict. Finally, latent topics during each MDGs, SDGs and COVID-19 period showed insignificant changes. However, compared to before the 2014 MDGs, strategic discourses tended to be discussed in detail. Moreover, we noted the change in global discourse from globalization to digital innovation. After the pandemic, the international community has emphasized the role of teachers and improved internet access for interaction. Such recommendations were intended to bridge the gap between countries including developing countries. As an alternative, UNESCO has suggested various partnership practices but there are nevertheless limitations that cannot be solved through a partnership or educational support. Therefore, reaching SDG4 requires global efforts to change the world by coordinating specific target countries and various social factors surrounding the countries' interior and exterior.

      Abstract: Prediction is a means of forecasting a future value by using and analyzing historical or current data. A popular neural network architecture used as a prediction model is the Recurrent Neural Network (RNN) because of its wide application and very high generalization performance. This study aims to improve the RNN prediction model’s accuracy using k-means grouping and PCA dimension reduction methods by comparing the five distance functions. Data were processed using Python software and the results obtained from the PCA calculation yielded three new variables or principal components out of the five examined. This study used an optimized RNN prediction model with k-means clustering by comparing the Euclidean, Manhattan, Canberra, Average, and Chebyshev distance functions as a measure of data grouping similarity to avoid being trapped in the local optimal solution. In addition, PCA dimension reduction was also used in facilitating multivariate data analysis. The k-means grouping showed that the most optimal distance is the average function producing a DBI value of 0.60855 and converging at the 9th iteration. The RNN prediction model results evaluated based on the number of RMSE errors which was 0.83, while that of MAPE was 8.62%. Therefore, it was concluded that the K-means and PCA methods generated a more optimal prediction model for the RNN method.

      Abstract: Kerangas or heath forests are found on podzolised siliceous sands (spodosols), where gradually decomposing organic matter occurs on the soil’s surface. Changes in the extent of podzol development, soil consistency, and poor nutrient contents signify the unique properties of sandy soil in the heath forest at Rantau Abang, Terengganu, Malaysia. Unfortunately, the sandy soil’s chemical and physical properties are in critical condition due to human activities such as cutting and burning, impacting the sustainability of this ecosystem and its ground cover of shrubs, sparse grass and sedge. Therefore, it is crucial to study the properties of sandy soils in heath forests before their extinction. This analyzed the physical and chemical attributes of heath forest sandy soils regarding heavy metal toxicity, pH, concentrations of carbon, nitrogen, available phosphorus, cation exchange capacity (CEC), allelochemical compounds, total phenolic content in the soil, soil colour, and soil texture. The solid was found to be nutrient-deprived due to its extreme acidity and toxicity. The results showed that allelochemical matters were higher in plants but not in the soil attributes and the water bodies, along with a highly active response in young plant tissues due to their sources of phenolic content. Remarkably, the overall phenolic content was observed to be considerably high in the semi-mature phase of vegetation.
