Climate Change Vulnerability Assessment and Adaptation: A Comparative Analysis of Reports Produced for Local Governments in South Africa and South East Queensland, Australia
No full textClimate change is dominating social, political and economic agendas. Because of the salience of the issue, scientists, researchers and consultants have developed a plethora of climate adaptation strategies. In this article I analyse two such strategies: Adapting South African Cities and Towns: A Local Government Guide to Climate Change Adaptation Planning by Ziervogel and Methner; and Climate Change Vulnerability in South East Queensland: A Spatial and Sectoral Assessment by Choy et al. For this analysis I utilised the PULSE3 analytical framework. My analysis indicated that the two adaptation strategies were predominantly positivist in scientific orientation. Other paradigms and theories are also applicable in explaining the issue of climate change and how to adapt to it.Political Science
An assessment of electronic waste management practices in Collins Chabane local municipality, Limpopo Province, South Africa
No full textText in English with summaries in Tsonga and SepediElectronic waste (e-waste) is a millennium challenge due to the rapid growth of the usage of electronic devices and appliances, the gradual improvement of living standards, and the life of technology we are living in. Recently, COVID-19 has added to the pressure on the usage of information and communications technology (ICT), leading to a super-growth of e-waste. The world has entered the 4th industrial revolution, and voluminous amounts of e-waste have been generated. Less developed regions are already facing greater challenges due to their failure to address the challenges presented by e-waste appropriately. Numerous studies on e-waste management in South Africa have been conducted, but most scholars have focused on the larger metropolitan areas of the nation, overlooking the local municipalities. Thus, this study was conducted with the aim of assessing e-waste management practices, including collection, transportation, and disposal, at Collins Chabane Local Municipality.
Primary data was collected through checklist observations, closed-ended questionnaires, and semi-structured interviews. Secondary data was collected from different sources such as the internet, government publications (the Gazette), journals, and audit reports from Collins Chabane Local Municipality. Data was analysed using Statistical Package for Social Science (SPSS) version 27, Microsoft Excel, and the logit statistical model. The logit regression model was employed to determine the factors influencing the community’s awareness of electronic waste in Collins Chabane Local Municipality.
This study found that Collins Chabane Local Municipality does not have any policy in place to manage or regulate e-waste management. Furthermore, e-waste is treated the same as other streams of waste. Communities were found to lack or have less knowledge of e-waste. It was found to have no single company dealing with e-waste recycling and related matters within the study area, leading to incorrect handling of e-waste by most community members, who ended up keeping obsolete e-waste in their storerooms. This study established further that lack of regulation of the e-waste stream has led to failure to know the specific amount of e-waste generated at Collins Chabane Local Municipality in terms of tons; however, the study managed to establish the types of e-waste generated the most. Moreover, the role of waste pickers in the reduction of e-waste that is supposed to reach landfill sites is not recognised by relevant bodies dealing with waste.Thyaka ra xielekitironiki i ntlhontlho wa malembexidzana hikwalaho ka ku kula ko hatlisa ka ku tirhisiwa ka switirhisiwa swa xielekitironiki, antswiso wo nonoka wa mipimo ya ku hanya, na vutomi bya thekinoloji lebyi hi hanyaka eka byona.

Strategies for the facilitation of Slef-Leadership among ward nurses in a nurse-led Critical Care Outreach Service
No full textAbstract
Introduction: Nurses are responsible for monitoring and providing nursing care to patients. The early detection of a patient
who is starting to deteriorate – and the activation of critical care outreach services (CCOS) – can improve patient outcomes.
However, the literature indicates that CCOS are underutilised. Self-leadership is a process whereby persons influence their
own behaviour.
Objective: The purpose of this study was to develop strategies for the facilitation of self-leadership in ward nurses that will
enable them to act proactively and promptly in utilising CCOS at a private hospital group in South Africa.
Methods: A sequential exploratory mixed-method research approach was followed to develop strategies for the facilitation
of self-leadership in nurses that will enable them to utilise CCOS proactively when a patient starts to deteriorate. An adapted
version of Neck and Milliman’s self-leadership strategic framework was used as the methodological steps of the study.
Results: The quantitative analysis extracted eight factors, which were used as the departure point to develop strategies for
the facilitation of self-leadership among nurses in a CCOS. Five strategies were developed that related to self-motivation, role
models, patient outcome, assistance and guidance from CCOS, and the power of self-confirmation; these strategies aligned
with the themes and categories extracted from the qualitative data analysis.
Conclusion: There is a need for self-leadership among nurses in a CCOS.Health Studie
Storytelling : an innovative educational package for teaching midwives in Uganda
Get PDFTransformation and innovation have become especially important in nursing and midwifery education. Educators in this area need various pedagogical approaches beyond traditional strategies of teaching and learning to meet tomorrow’s health care delivery system challenges. The purpose of this study was to explore and describe the use of storytelling as an innovative educational package for teaching midwives.
Phase I subphase 1 includes an integrative literature review used to explore and describe the meaning of the concept ‘storytelling’ as a teaching strategy in midwifery education. Phase I subphase 2 explores the experiences of midwives in managing midwifery health care by analysing their reflective essays on incidents in their midwifery practice. A qualitative research approach using an interpretative phenomenology design was used, drawing on convenient sampling of fifteen (15) reflective essays from Phase I subphase 2. The participants were all final year midwifery students who had already learnt how to write reflective essays for their clinical case studies using the Gibbs Model of Reflection from learning by doing.
Phase II developed four stories which had emerged from the four major themes of the reflective essays using Thaddeus and Maine’s Three Delay Model. The four themes are: delay in seeking care, delay in reaching health care, delay in receiving care, and no delays.
Phase III validated the stories for accuracy, and for application as a teaching strategy with midwifery education experts.
In Phase IV, the findings of both Phases I and II, were integrated. Four contextual real-life stories were analysed and from these an educational package using storytelling as an innovative teaching strategy for teaching midwives was developed. Field experts validated the storytelling package which provides step-by-step instructions for preparing midwifery educators for storytelling classroom sessions.
Recommendations are provided for nursing and midwifery educators, the management of the nursing education institutions, other stakeholders such as the Uganda Nursing and Midwifery Council (UNMC) and government, on the inclusion of this innovative teaching strategy in the curriculum and training methods of academic and clinical courses.Ph.

. The search considers final states with zero or one charged lepton (electron or muon), at least one b-jet and large missing transverse momentum. In addition, a result from a previous search considering two-charged-lepton final states is included in the interpretation of the results. The data are found to be in good agreement with the Standard Model predictions and the results are interpreted in terms of 95% confidence-level exclusion limits in the context of a class of dark matter models involving an extended two-Higgs-doublet sector together with a pseudoscalar mediator particle. The search is particularly sensitive to on-shell production of the charged Higgs boson state,

Enhancing mathematics teachers' professional development for creative teaching in Addis Ababa secondary schools
No full textThe Ethiopian education system is imported from the West, and the traditional method of instruction (pouring information) in the ICT revolution era wastes time and resources. Learners can get more information about mathematics using portable devices such as cell phones, tablets, or personal computers at their homes. The imported school system doubled with the ICT revolution, demanding a change in the role of teachers. Therefore, teachers need training on the new requirements of teaching mathematics. This transcendental phenomenological study aimed to explore the impact of continuous professional development on equipping mathematics teachers with the skill of creative teaching in Addis Ababa secondary schools. The study was framed in the central question: To what extent does the existing continuous professional development program equip secondary school mathematics teachers with the skill of creative teaching? To that end, a qualitative study was done. Six participants were selected using purposive sampling, two from each of the three types of schools: Government, Private, and NGO. Data was collected through one-on-one interviews, lesson observation, and document analysis.
Using Woods' features of creative teaching (Relevance, Control, Ownership, Innovation) and Cremin's dimensions of creative practice (Personal quality, Pedagogy, and Classroom ethos) as a lens to judge teachers' instruction methods, the implication is that teachers fail to practice creative teaching techniques. The study findings revealed that teachers are applying the traditional instruction method, transmitting what is transcribed in the textbook without any adjustment, including its deficiencies. The textbook content lacks logical order among chapters, the tasks are poor in connecting school and out-of-school experiences and are not supportive in fostering teachers' autonomy. The CPD program teachers' experience did not help improve their teaching practices and is not more than for report writing. In this study, the role of teachers in this ICT revolution era has been described; moreover, this study also contributes to the field of mathematics education by paving the way for debate among mathematics education educators on the role of teachers in the ICT and AI (Chat Gpt, Bing Chat) era. The study recommends that the CPD program should equip teachers with creative, challenging, and unusual teaching skills by considering the challenges and opportunities of ICT, real-life mathematics knowledge, the textbook's nature, and teachers' role in this era for meaningful teaching.D.

The perceived quality of strategic management within a private organisation in Ekurhuleni district
No full textIn today's fast-paced business world, strategic management plays a crucial role in keeping
businesses ahead of the competition. However, there is little research on how private
organisations perceive the quality of their strategic practices, tools, and decisions. To fill this
gap, the researcher conducted a study analysing the strategic management quality of a
private organisation in Ekurhuleni. Findings were made that high-quality strategic decisionmaking
processes and tools are essential for small business stakeholders. It is crucial for
business leaders and decision-makers to understand the importance of implementing
comprehensive, quality strategic management practices to improve their organisation's
strategic practices and gain a better understanding of the correlation between strategic
management and instruments and decisions of strategic practices. These results
demonstrate the need for private small businesses to develop strategic frameworks that
prioritize long-term planning, realistic objectives, and identifying challenges and
opportunities to sustain their existence. This study investigated the perceived quality of
strategic management in a private organisation for practical and academic purposes and the
findings are consistent that high level perceptions of strategic practices and related concepts
are valued by stakeholders, even in small private organisations.M. B.A.Graduate School of Business Leadershi
The performance and learning difficulties of Grade 10 learners in solving euclidean geometry problems in Tshwane West District
No full textThere is a growing trend of declining performance in the final year (Grade 12) mathematics examinations in the South African public school system. The study aimed to evaluate Grade 10 learners in the Tshwane West District on their performance and learning difficulties in solving Euclidean Geometry problems. The study utilized a mixed method approach under a pragmatic paradigm to determine the achievement and the challenges experienced by learners when solving Euclidean geometry problems. The Van Hiele levels of geometry thinking and constructivist theory, underpinned the theoretical framework used to determine the actual performance and how they understand geometry concepts. The population was Grade 10 learners, and the sample size was 80 learners, purposively selected from two secondary schools in the Tshwane West district in the Gauteng Province. The Geometric Achievement Test instrument was used to determine firstly, the overall performance of learners in Euclidean geometry, secondly, the level of Grade 10 learners on Van Hiele levels of thinking and lastly to specify the area where learners have the most difficulties when engaging with geometry problems. A semi-structured interview guide and class observation checklist were used to further understand the challenges experienced by grade 10 when they are faced with Euclidean geometry questions.
The findings from this study showed the underperformance of learners in three Euclidean geometry topics: these included parallel lines, congruency, and parallelograms. The findings further indicated that the low performance was a result of a lack of understanding of the computational and spatial thinking that characterises Euclidean geometry. These findings were supported by the quantitative findings of the study.
The pass mark stipulated in Euclidean geometry is 30%; less than 10% of the participants in the GAT obtained 30% and above. The findings of the study showed that less than 5% of the learners obtained a score of 38 on the achievement test, which was the highest score obtained. Of the 80 participants, 1,25% (1 of 80) obtained a score of 2. Euclidean geometry requires learners to use their spatial and logical skills in solving mathematical questions; for this sample, making connections and comprehending the visual and spatial aspects of parallel lines, congruency, and parallelograms were found to be difficult. The findings also showed that learner lack an understanding of the properties of parallel lines, resulted in difficulties in calculating the magnitudes of unknown angles using these properties. The findings further indicated that Grade 10 learners have difficulty solving geometry requiring knowledge of corresponding, alternating, and co-interior angles. A notable difficulty was that for the learners to apply the conditions of congruency and execute the proof for parallelograms, learners must understand parallel lines and its properties. Teachers must ensure that learners understand the procedures of naming angles correctly. The understanding of properties of parallel lines, congruency, and proof of parallelograms is essential for enhancing learner abilities in Euclidean geometry.M. Ed.

Health performance and economic growth in sub-Saharan Africa: new evidence based on quantile regressions
No full textThe present study investigates the nexus between health performance dynamics and economic growth in 43 countries in sub-Saharan Africa for the period 2004-2018. Four health performance dynamics are used, notably: total life expectancy, male life expectancy, female life expectancy and risk of maternal death. The empirical evidence is based on quantile regressions in order to put into perspective the conditional distribution of economic growth.
The following findings are established: (i) total life expectancy and male life expectancy increase economic growth exclusively in the 10th and 90th quantiles of economic growth; (ii) female life expectancy boosts economic growth in the 90th quantile of economic growth and (iii) the risk of maternal death reduces economic growth in the 75th and 90th quantiles of economic growth. Policy implications are discussed. The study complements the literature on the nexus between health performance and economic growth by assessing the nexuses throughout the conditional distribution of economic growth.Economic
