The appealability of decisions to certify class actions: Where are we now? A proposed approach after Stellenbosch University Law Clinic v Lifestyle Direct Group International (Pty) Ltd (WCC)
Authors: Broodryk Theo
Published: May 2023

Decisions refusing to certify class proceedings are appealable. The position regarding the appealability of decisions certifying class actions is, however, less clear. Regrettably, in Stellenbosch University Law Clinic v Lifestyle Direct Group International (Pty) Ltd [2021] JOL 51475 (WCC), the court did not give a final ruling on whether a decision to certify a class action is appealable. Gamble J merely assumed, without deciding, that his decision in Stellenbosch University Law Clinic v Lifestyle Direct Group International (Pty) Ltd 2022 (2) SA 237 (WCC) to certify the class action was appealable. This article aims to clarify the preferred approach when deciding whether to permit an appeal against a decision to certify a class action.

55 (At Least) and not out of the Learning Game
Authors: Ellis Bronwyn J.
Published: May 2023

This article explores older students‘ perceptions of formal, non-formal and informal learning in regional South Australia. Drawing on earlier studies as well as a continuing one, it compares: the study motivations of students aged 55 and older enrolled formally in university undergraduate programs; the learning motivations of University of the Third Age (U3A) members enrolled in various non-formal classes; and the learning of older people in other community organisations.
Research focusing on these different groups of older learners was conducted via anonymous surveys. Members of a particular U3A branch, sponsored by the regional university campus at which it meets, took part some years ago in a study that investigated the importance attributed by them to continued learning and the impact on them of their U3A participation. Social as well as educational benefits were identified. In a later study investigating the reciprocal contributions of U3A and university campus, U3A members were also asked about their possible interest in undertaking formal university study, while university staff were asked how they thought these older students would fit in as enrolled undergraduate students. More recently, an online survey allowed university students of more mature years to provide an insight into their higher education experiences, both highlights and challenges, and the contributions that they were able to make to their classes from their life experience.
The main focus of this paper draws on data from an ongoing survey of past, present and potential links between the university campus and local organisations with an older membership. It reveals how these age-mates of the older participants in the earlier studies regard the possibility of formal university study for themselves.The article argues that in a just, inclusive society all groups within it, including older people resident in more remote areas, should have access to lifelong learning opportunities, including both non-formal continuing education and formal higher education.
Rural Schools and Traditional Knowledge
Authors: Barter Barbara
Published: May 2023

Given the present pace of educational globalization, educators – especially in rural schools – will benefit from an awareness of traditional knowledge as a significant contributor to sustainability. Many countries operate through a system whereby major decision making, especially in such areas as education and health, emanate from state levels of governance; and these decisions are often uni-directional. In education this implies a ‘one size fits all’ philosophy that forces educator compliance with accountability driven pedagogy and curricula subjected to competitive standardized testing processes that are caught up in market driven values. Aims of a research pilot (Harris & Barter, 2011-2012) in one province in Canada, and through a critical pedagogy of place and participatory research, were to introduce students and community members in rural areas to issues of local relevance; to develop school curricula that call for students-as-researchers; and, as an example of local knowledge and relevance, to focus on food practices (past, present, and as future possibility).
Initial findings of the pilot indicate the changing nature of rural life that includes a move from remoteness to semi-isolation brought about with the building of roads and effective ferry connections, transient populations seeking seasonal employment, and a growing awareness of people’s need to revive past practices of food production. We found as well, examples of extraordinary innovation in food cultivation and food harvesting that drew on local and traditional knowledge. Finally, we experienced success in incorporating traditional knowledge into existing curriculum. This we did by varying ways of knowing and experiencing through the arts. For us as researchers, two important concepts permeated this research, critical pedagogy of place and traditional knowledge. In this paper, situated in a framework of cultural and social resistance to economic globalization, I describe initial efforts of the pilot project in expanding the discourse of rural studies, exploring traditional and local rural knowledge, and increasing rural agency. While providing a brief overview of the project, its specific purpose is to highlight the relevance of traditional knowledge as a significant contributor to sustainable global growth. I think of the potential that such knowledge, which often originates from rural environments, has to represent an alternative to consumer dependence.

Published: May 2023

One of the factors that influence the success of student learning is motivation. Motivation is one of the impulses contained in humans to want to do an act in order to achieve certain goals. In practice, distance or indoor (online) learning causes a lot of loss of motivation or demotivation of students as educational objects. According to the findings, prior to the pandemic, the most important characteristics that contributed to a lack of intrinsic motivation in students were low test scores, poor school facilities, learning content and resources, teacher competence and teaching style, and low test scores. On the other side, once the pandemic happened, the most notable variables that were demotivating people were poor test results, insufficient teacher competency and teaching style, inadequate school facilities, learning content and resources, and a lack of intrinsic desire.

Traditional performance management has weaknesses and is no longer suitable for business organizations to enter into very tight competition in the global market. Traditional performance management must be abandoned and replaced by implementing a new performance management. Performance management improvements are carried out on an ongoing basis to deliver the best performance of employees, teams and organizations. In order to achieve the effectiveness of performance management, business organizations need to develop supervision in improving performance management. The performance management model which consists of four stages (planning, implementing, reflecting, and compensating) can be used to improve performance management.

Students’ Creative Writings Mirroring the Social Reality
Authors: Paneru Pragya
Published: May 2023

This article analyses a total of forty-six students’ writings from Grade 11 to master’s level published in one of the college’s annual magazines. Among them 24 are females and 22 are males. This research uses a qualitative content analysis method to analyze the students’ writings under various topics and genres to unearth their concerns. Although there are multiple studies on students’ creative writings focusing on the technical and gender aspects, only a few studies focus on the issues reflected in their contents. This research believes that students’ creative writings are significant as they give information about the issues, interests, and concerns from students’ perspectives. The students’ writings also reflect their concerns and awareness of students regarding various social issues in their writings. The findings from this study revealed that students are concerned about multiple social and political issues in Nepal such as poverty, political corruption, cultural issues, gender discrimination, caste discrimination, and women issues.
Moreover, life is a dominant theme in both male and female writings and they are concerned about their life, future goals, and responsibility toward their parents. Some shared themes are the challenges of staying away from parents for study purposes, caste discrimination, gender discrimination, poverty, child labor, and women-related issues. Females have written personalized writings with varieties of issues and dark themes than males and the themes in their writings suggest their struggle in a patriarchal society, social restrictions, gender discrimination, and women violence against males’ writings on general themes such as loss of human values, loss of culture, and struggle of orphaned children.
Risk and Legal Regulation of Algorithm Application in Insider Trading Supervision
Authors: Chen Laiyao
Published: May 2023

Insider trading is a kind of information manipulation behavior in the securities market. The insider trading has brought great damage to the securities market in recent years, so securities regulatory authorities have begun to crack down on this kind of illegal behavior. With the application of algorithms in the field of supervision, regulators can accurately identify insider trading behaviors through big data analysis and other technologies, with which the efficiency of supervision was greatly improved. However, the application of algorithms in the supervision of insider trading is prone to cause various legal risks, such as the inaccurate transformation between algorithms and regulatory regulations, the imperfection of algorithms, the infringement of private data rights, etc. The legitimate rights of the regulated objects might be endangered by above risks. Therefore, it’s necessary to establish risk prevention and legal regulation to cope with the algorithms in the filed of insider trading supervision from three aspects of rule transformation, technical supervision and data security. In this way, the property rights, data rights, privacy rights of financial investors, listed companies and other stakeholders are protected.

Published: May 2023

This article will investigate how a microcelebrity YouTuber named Rius Vernandes became a symbol for the birth of civil power in a digital society. His criticism vlog for Garuda Indonesia's business class services has drawn criticism from the airline, which has led to a legal case. Through the power of social media networks and YouTube, Rius Vernandes did what came to be called self-institutionalizing, by then breaking down the limits of social control through a new force; I am a YouTuber. This article uses an exploratory approach to the development of the case to the conclusion that the case was stopped reporting by related parties. Through a theoretical study of the technique of self-representation, this paper examines how the cultural logic of the celebrification process of Rius Vernandes, led to the "victory" of civil power. The phenomenon of micro-celebrity in this paper is assumed as the construction of identity and self image in front of peer-users, to get public sympathy and attention for the freedom of criticism. The exploration is emphasized on how the strategic steps taken by Rius Viernandes by placing themselves as part of a critical digital community. The case has become one of the contemporary phenomena of the revolutionary power of criticism, breaking the border of social control by the new form of civil power through the internet in the era of digital media.
The UNEP governance and its challenge towards mechanism of NGO engagement in Indonesia
Authors: Paramitha Gracia , Djati Sundring
Published: May 2023

Since the globalization era and the end of the Cold War, the environment is the third agenda after international security and the global economy (Porter and Brown, 1996). In 1972, the Stockholm Conference, the first global environmental meeting, led to the establishment of the United Nations of Environment Programme (UNEP) in 1974. Its aim was for managing global environmental issues under the mandate of the United Nations. Since 1992, there has been a framework to engage civil societies in the UN system and environmental governance, which is called Major Groups. They are children and youth, women, trade unions, farmers, indigenous communities, scientists, business sectors, and NGOs. This Major Groups regularly hold an annual meeting along with UNEP Governing Council Meeting. However, their representatives have not fully participated in the decision-making process. The main reasons were complicated accreditation for Major Groups, lack of access, lack of financial support, and lack of coordination in terms of doing public consultation with the UNEP Governing Council. In the case of Indonesia, no NGO has been included in UNEP-accredited NGOs (UNEP Document, 2013). The research question is why UNEP governance does not fully influence the NGOs in Indonesia. This paper aims to analyze the factors of the weak UNEP governance using a theoretical framework for civic engagement. In its theory, there are 3 key indicators: information, participation, and consultation. This paper used a qualitative method by collecting data and conducting in-depth interviews with WWF Indonesia, WALHI (Indonesian Environmental Forum), and Indonesia Berkebun (Gardening Indonesia). The key finding of the research is that UNEP has weak capability in doing public consultation and national outreach. Hence, UNEP should create National Committee, which strengthens the link between Indonesian NGOs and ASEAN.

African higher education institutions catching up: The potential of 4IR in closing the digital deficits
Authors: Msila Vuyisile
Published: May 2023

The new digital cultures brought by the Fourth Industrial Revolution (4IR) are forcing universities to transform their practices as they prepare students for a future that will magnify the use of digital tools. Throughout the world, institutions of higher learning are gearing to maximise the benefits that could be gained from the 4IR. The concept, engaged university, ensures that the uniiversities will not leave the communities around them behind as they prepare for the future, for universities will play a huge role in contributing to the progress in societies. This conceptual article examines the opportunities of 4IR in African institutions of higher  learning. The 4IR has potential to solve many of the ills in Africa, for the African societies still suffer ill health, poverty and illiteracy. The promise of the 4IR brings hope of    minimising these ills as Africa moves towards advancement. Furthermore, there has been much balkanisation in African education hence some believe that the 4IR can create links between institutions within states and the entire African continent. Not only will new technologies transform research, scholarship and teaching, but these would also have impact on bringing forth new epistemologies although there is still a battle for more resources. The major challenge for 4IR in Africa will be to create links between new technological cultures and African cultures; universities are well-placed to face such challenges.
Mediating Effects of Reactance in the Relationship Between Adult Attachment and Working Alliance in CBT: A Structural Equation Modelling Approach
Authors: Ioannidis Pavlos
Published: May 2023

The aetiological effects of attachment dimensions on therapeutic relationships, a determining factor for client experiences and outcomes, have been extensively documented in the psychotherapeutic literature. Especially in CBT, the possible pathways through which attachment affects the working alliance is a severely under-explored area of scientific inquiry. Hence, the present study sought to examine the possible mediating role of therapeutic reactance in the attachment dimensions-working alliance link. In a sample of 224 CBT clients (182 women and 42 men) with a mean age of 25.2 years (SD=3,87), the Experiences in Close Relationships-Revised (ECR-R), Working Alliance Inventory-Client (WAI-C) and Therapeutic Reactance Scale (TRS) were distributed, and Structural Equation Modelling (SEM) procedures revealed that therapeutic reactance fully mediates the attachment-working alliance link with an indirect effect of β=-.080, t=-3.402, p<.05 and it partially mediates the attachment avoidance-working alliance link with β=-.054, t=-2.539, p<.05 explaining 19.5% and 15% of the variance in the effect of each attachment dimension on working alliance, respectively. Findings suggest that therapeutic reactance effectively captures a large proportion of the influence of adult attachment on working alliance in CBT, deeming it a promising area for further investigation with major practical applications in CBT. Future studies utilizing longitudinal, qualitative, and clinical trial methodologies could focus on reactance prevention strategies to promote better therapeutic relationships and therefore, client outcomes.

Published: May 2023

Conflicts that occur in oil palm plantations do not always have a negative impact, but there are also positive sides as driving factors for change. The research aims to analyze the positive impact of conflict on the rise of local entrepreneurs and the supporting factors for building businesses in swamp buffalo farming communities in South Kalimantan Province. The rise of local entrepreneurs in swamp buffalo farmers not only contributed to the turning of the wheels of the rural economy but also contributed to the study of social sciences. The research was conducted by qualitative methods. The research sites are central villages of swamp buffalo farms in South Kalimantan Province, which have been entered by oil palm plantations. Interviews were conducted with farmers, formal and non-formal leaders, wholesaler, members of the police, members of NGOs, and other community members who had similar businesses. There were 84 people. Observations were made on the new business objects of the breeders.  Document studies and audio-visual recordings are carried out related to the activities of breeders. Data analysis uses an ethical perspective so that an overview of entrepreneurship carried out by swamp buffalo breeders is obtained from the researcher's point of view.  The results showed that there was a positive impact on conflict for swamp buffalo farmers, namely the development of the entrepreneurial spirit. This is shown by the development of natural sources of livelihood other than raising swamp buffalo, which are developed based on natural conditions so that sustainable businesses are formed. The development of entrepreneurial spirit is determined by internal factors, namely trade culture and the habit of managing a business independently; and external in the form of market certainty to accommodate farmers ' products. The conclusion is that swamp buffalo breeders can become local entrepreneurs.  The implication is that there is an economic turnover in rural areas.

TOXIC KINETICS OF CIPROFLOXACIN IN MICE
Authors: M. AMIN S. , K. IBRAHIM F.
Published: May 2023

Ciprofloxacin belongs to a class of drugs called quinolone antibiotics. It is widely used in humans and animals. Excessive use of it increases the risk of poisoning, which occurs due to medical errors or due to the use of high doses to overcome antibiotic resistance. Due to the lack of research on its toxic kinetics. Therefore, the goal of our research was to measure its toxic kinetics in mice. First, the median lethal dose (LD50) was accounted for by the Dixon method. It was 1280,5 mg/kg body weight. Then mice were injected intraperitoneally at a dose of 800 mg/kg body weight. Blood samples were collected from mice (five/each time interval) after zero, 0.15, 0.30, 0.45, 1, 2, and 4 hours after drug administration. Its concentration in plasma was accounted for by the HPLC method. Its highest plasma concentration was 0.88μ g/ml in 15 minutes of injection, and the second rise was 0.76 in 45 minutes of injection. Its toxic kinetic parameters were calculated by noncompartmental analysis. The t1/2 was 1 .52 h with a Vss of 2551.18 (mg)/(µg/ml) and a CL of 1162,26 ( mg)/(µg/ml)/h . The MRT for the drug was 1,31 hours and the AUC (0-∞) was 0,69μ g/ml*h . In conclusion, the acute toxicity of ciprofloxacin in the peritoneum is low and the data show the toxic kinetic profile of a single peritoneal dose of ciprofloxacin in mice
LIGHTWEIGHT IMAGE COMPRESSION USING POLYNOMIAL AND TRANSFORM CODING
Authors: J. AHMED Zainab , E. GEORGE Loay
Published: May 2023

This article implies a proposal for a lossy compression system using polynomial coding with color and gray images. The proposed system contains two main parts: coding and decoding. In the coding, each block of the image is represented as a twodimensional quadratic polynomial to prune the main low variation component to get better compression gain. The size of each image block is variable depending on quadtree partitioning. Then, the signal residue of the polynomial representation (i.e., the residue is the component produced due to subtraction of polynomial from the original image); then the polynomial coefficients and the residue are encoded, separately in different manners. The transformation coding (i.e., Discrete Cosine transform or bi-Orthogonal Wavelet transform) is used to compress the residual component of each band. The applied transform on the residue band can map the values more compactly. Also, uniform quantization is applied to the residue to effectively reduce the number of consumed bits required to represent the residue. Various encoding operations are performed to encode the polynomial coefficients. Finally, the all-out output is compressed using an LZW encoder. The results of the conducted test indicated that the introduced structure is lightweight and its implementation is straightforward. Besides that, it can lead to high compression ratios with an acceptable fidelity tolerance. The results are comparable to those of the current study and it has made progress.
THE EFFECT OF BACKGROUND VACUUM PRESSURE ON THE LENGTH OF GAS DISCHARGE PLASMA BY USING ALUMINUM ELECTRODES
Authors: R. ABDULAMEER Mohammed
Published: May 2023

Length of plasma generated by dc gas discharge under different vacuum pressures was studied experimentally. The cylindrical discharge tube of length 2m was evacuated under vacuum pressure range (0.1-0.5) mbar at constant external working dc voltage 1500V. It was found that the plasma length (L) increased exponentially with increasing of background vacuum air pressure. Empirical equation has been obtained between plasma length and gas pressure by using Logistic model of curve fitting. As vacuum pressure increases the plasma length increases due to collisions, ionizations, and diffusions of electrons and ions.

Hypothyroidism is a medical state referring to the lack of secretion of thyroid hormones (THs) in the body. It occurs when the thyroid gland starts to produce and secrete a small amount of thyroid hormones Thyroxine (T4) and Triiodothyronin (T3), this will affect body cells, resulting in a slowing of the body's metabolic rate, weight gain, and tachycardia. Visfatin and adiponectin are two hormones from type adipokine produced from fat tissue. Those hormones have an important function in protein, lipid and glucose metabolism, as well their role in energy expenditure. Eighty cases of both sexes (male and female) have been collected from the hospitals and private laboratories of Iraq. They are divided into two groups. Group1 (control group) includes (40) healthy individuals and the group2 includes (40) hypothyroid patients, All patients and controls underwent history taking, determination of levels of visfatin, adiponectin, Thyroid-stimulating hormone (TSH), T4, T3 and lipid profile. The results showed that Visfatin levels in group 2 were significantly higher than in group1, on the other hand, Adiponectin levels decreased in group2 compared with the control group at probability (P≤ 0.01), and concerning the lipid profile, there was a significant increase in the levels of lipid parameters total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL-c) and very low density lipoprotein (VLDL) while high density lipoprotein (HDL) was decreased in group2 compared to control group

THE CONTRACTION PROPERTY AND THE EQUIVALENC OF (LIPSCHITZ AND ARCWISE COMPLETENESS)
Authors: Gazi Nsaif ALBU_AMER Ansam , Abdullah ABED Sami
Published: May 2023

Researchers investigate the completeness and shrinkage properties in metric spaces in this paper as well as demonstrate that the shrinking characteristic entails Lipschitz- wholeness or arswise- wholeness in metric spaces. The contraction feature, on the other hand, does not entail completion in metric spaces. We demonstrate that a locally Lipschitz-linked metric area has the shrinkage characteristic if it is Lipschitz- whole and an arswise-linked metric area is arswise- entire if X has the intense shrinkage characteristic. The method applied by Borwein to generate a shrinkage map is crucial for showing Lipschitz-completeness of the space.
