Beschreibung: The success of any preventive healthcare programme is reliant on a functional healthcare system. Within this system of care, healthcare professionals, including audiologists, can only practice safely and effectively if they possess an appreciation of the complexities and challenges that exist in that context. Where healthcare professionals have such awareness that aids them to recognise opportunities for errors that can cause patients harm and where they take steps to prevent these mistakes is where preventive audiology is positioned. This edited book, Complexities and Challenges in Preventive Audiology: An African Perspective, is a sequel to another book by the current editor titled Preventive Audiology: An African Perspective. While in the process of editing that book, the editor identified that a lacuna of contextually relevant collation of evidence on complexities and challenges faced by the field of audiology within the African context in implementing preventive audiology existed. The goal of this book is to delve into these complexities and challenges for various key areas in audiology. All chapters deliberate on evidence-based perspectives grounded in the African context, with deliberate and preferential reliance on contemporary locally relevant evidence that allows for accurate reflection of current complexities and challenges in ear and hearing care delivery within the African context. Contributors were encouraged to be as comprehensive as possible in their review of the literature within the African context, where available. Complexities brought about by context, such as cultural and linguistic diversity as well as traditional and alternative healthcare, on preventive audiology within the South African context, are also covered in this book. As each chapter explores prevailing complexities and challenges, potential solutions and recommendations for all challenges identified are also offered, having carefully and deliberately engaged with local evidence, local context, and local policies and regulations to ensure an Afrocentric contribution to the world of evidence. All chapters in the book have a goal of ensuring that increased efforts are directed towards the provision of clinical services that are driven through best practice by contextually relevant and responsive evidence.

Publikationsdatum: 2024-04-08

Beschreibung: This publication deals with a biblical theology of prayer based on the New Testament. It forms the second of a two-volume publication on a biblical theology of prayer, dealing with the concept of prayer in the Old and New Testament, respectively. This New Testament volume begins with an introduction on prayer and worship in early Jewish tradition, followed by eleven chapters dealing with New Testament corpora. It concludes with a final chapter synthesising the findings of the respective investigations of the Old and New Testament corpora to provide a summative theological perspective of the development of the concept of prayer through scripture. Prayer forms a major and continuous theme throughout the biblical text. Prayer was an integral part of the religious existence of God’s people in both the Old and New Testament. It underwent its greatest developments during, after and as a result of the Exile and was deepened and transformed in the New Testament. In both the Old and the New Testament, God is the sole ‘addressee’ of his people’s prayer. This conviction continued into the New Testament, but was broadened with Trinitarian elements of worship, adoration and intercession. A biblical theological investigation is chosen as methodology. Since all the biblical books form part of one canonical text, the assumption is that the various theologies about prayer being displayed in these books can be synthesised into a developing meta-theology about prayer. As the Old and New Testament form part of the canonical text, the results about prayer in the Old Testament can be brought into play with the results about prayer in the New Testament. This eventually leads toward an overarching biblical theology of prayer.

Beschreibung: The focus of this book is original research regarding the implementation of problem-based learning and pedagogies of play as active approaches to foster self-directed learning. With the Fourth Industrial Revolution (4IR) in mind, educational institutions need to rethink teaching and learning for the future. As such, active engagement can be encouraged, as evident in this book, where problem-based learning drives learning through real-world problems, while pedagogy of play focuses on innovative environments where the action of play and learning are integrated with the aim of developing SDL. The following are addressed in the chapters: an overview of problem-based learning and pedagogy of play, metaliteracy, playful problem-based learning tasks, computational thinking in game-based tasks and geometry, solving puzzles, applying LEGO®, using drama as the pedagogy of play and implementing educational robotics. The empirical research findings disseminated in this book aim to inspire academics in the research focus area of self-directed learning with active learning approaches in the school and tertiary classroom that hold affordances to enhance 21st-century skills. Active learning is an umbrella term for pedagogies that mainstream student engagement, such as problem-based learning, cooperative learning, gamification, role-play and drama. This scholarly book highlights various engaging pedagogies.

Publikationsdatum: 2024-04-06

Beschreibung: This book endeavours to outline case studies that promote sustainable Local Economic Development (LED) initiatives. It is generally believed that local governments are the foot soldiers of LED. However, this seems to be a myth, as local governments in South Africa and elsewhere have not yet fulfilled this mandate and have been struggling for several years to implement LED initiatives. The distinctive merit of this book lies in the way it combines the South African context with the wider international development context in ways that there is a flow of information and ideas both ways. The book is an essential part of this sequence of ideas development and action at a critical time for strategic action directed at a sustainable future. It showcases case studies and responses to the impacts of globalisation as a bridge between urban/rural and institutional action and reveals avenues for local government leadership in communities, research, student engagement and wider interactions.

Beschreibung: This book’s research is on online pedagogical approaches devised by teacher educators and researchers to circumvent a face-to-face curriculum delivery during the COVID-19 pandemic. The challenge faced by educators was that they were uncertain of how to use digital technologies in teaching, learning and assessment productively. This book reports on case studies on teaching student teachers with technology in a way that advanced not only communication but also the cognitive growth of students in relation to disciplinary knowledge. The scholars from South African universities used both conceptual and empirical methodologies, mostly in qualitative set-ups. The scholarly contributions in this book are varied. They cover theoretical nuances for ICT use in education, considerations for the use of computers in the classroom, pedagogical thinking and pedagogical integration of ICTs in education, affordances of iPads in visible teaching and learning, supporting student cognition in Languages, Mathematics, Science, Engineering Graphics and Design with ICTs. The use of software applications such as GeoGebra and Excel in teaching and learning mathematics is researched, among others. The rich discussions that emerged from their research enable academics to learn from ‘others’ innovative moments that came as a result of pandemic pressure. The recommendations in this book can be used in blended learning beyond the COVID-19 era, as curriculum delivery methods are bound to change. The value of this book is that it reports on pedagogical innovations in using digital technologies in teacher education. Researchers have an opportunity to learn from this book how to deal with the tantalising teaching and learning problem of our time: How can the use of digital technology transform teaching and learning in general and teacher education in particular?

Beschreibung: Five manganese nodules from a range of deep-sea and fossil environments were selected for this study. Most samples were prepared for bulk analysis by grinding the material finely with a pestle in a porcelain mortar. However for samples Z2140 (ELT36.039-BT) and Timor (Wai_Bua_A) the nodule cores were discarded. Depending upon the chemical elements a varied range of analytical methods were used: X-Ray fluorescence, neutron activation, mass spectrometry and atomic absorption spectrometry. All samples were dried at 110°C for the determination of H2O+ loss. Structural water H2O- was determined by ignition at 1200°C (LOI) and total CO2 was measured by a Leco gasometric technique.

Beschreibung: Northern Patagonia (41–44°S) is affected by climatic, hydrological and oceanographic anomalies, which in synergy with processes such as global warming and acidification of the coastal oceans may affect the frequency and intensity of harmful algal blooms (HABs). Greater frequency of HABs has been reported in the southeastern Pacific Ocean, including blooms of the toxic dinoflagellate Karenia selliformis, causing massive mortality of marine fauna in the oceanic and coastal areas of Patagonia. The objective of this study was to determine the effects of temperature and pH interaction on the growth of K. selliformis (strain CREAN_KS02), since these factors have wide seasonal fluctuations in the Patagonian fjord ecosystem. The CREAN_KS02 strain isolated from the Aysén Region (43°S) was used in a factorial experiment with five pH levels (7.0, 7.4, 7.7, 8.1 and 9.0) and two temperatures (12 and 17 °C) during a period of 18–21 days. Results indicated a significant effect of temperature and pH interaction on growth rate (range 0.22 ± 0.00 to 0.08 ± 0.01 d−1) and maximum density (range 13,710 ± 2,616 to 2,385 ± 809 cells mL−1) of K. selliformis. The highest density and growth of K. selliformis was found at 12 °C with a reduced pH (7.0–7.7). The results suggest that the current environmental conditions of coastal Patagonia, waters of low temperature and relatively low pH, may be favorable for the development of blooms of this species during autumn. We suggest that there is natural plasticity of K. selliformis in a wide pH range (7.0–8.1) but in a narrow low temperature range (10.6–12.9 °C), values that are typically recorded in the oceanic region of northern Patagonia. In contrast, in an extreme climate change scenario (ocean warming and coastal acidification) in northern Patagonia, a negative effect on the growth of K. selliformis may be expected due to amplification of the acidification effects caused by the thermal stress of high temperature water.

Beschreibung: Recent marine climate change research has largely focused on the response of individual species to environmental changes including warming and acidification. The response of communities, driven by the direct effects of ocean change on individual species as well the cascade of indirect effects, has received far less study. We used several rocky intertidal species including crabs, whelks, juvenile abalone, and mussels to determine how feeding, growth, and interactions between species could be shifted by changing ocean conditions. Our 10 wk experiment revealed many complex outcomes which highlight the unpredictability of community-level responses. Contrary to our predictions, the largest impact of elevated CO2 was reduced crab feeding and survival, with a pH drop of 0.3 units. Surprisingly, whelks showed no response to higher temperatures or CO2 levels, while abalone shells grew 40% less under high CO2 conditions. Massive non-consumptive effects of crabs on whelks showed how important indirect effects can be in determining climate change responses. Predictions of species outcomes that account solely for physiological responses to climate change do not consider the potentially large role of indirect effects due to species interactions. For strongly linked species (e.g. predator-prey or competitor relationships), the indirect effects of climate change are much less known than direct effects, but may be far more powerful in reshaping future marine communities.

Beschreibung: Urban studies often rely on urban boundaries that have been defined by administrative units or by land use or land cover classification of satellite images. The final results of those boundaries is the categorization of urban/non-urban units in the form of a binary layer used to extract additional information (e.g., zonal statistic) from other geographical layers (e.g., land surface temperature or population density). Given the heterogeneous and continuous nature of the built-up area, binary representations contain a mixture of urban/non-urban areas that influence the results of following analyses. Here we present a way to move beyond the limitations of the binary urban/non-urban representations with a hierarchical watershed-based thresholding and segmentation approach that partitions the built-up area into more homogeneous units. The proposed algorithm, applied to the Global Human Settlement Layer, enables researchers and planners to define urban computational units in three ways - bin-unit, watershed-unit, and agglomeration-unit - depending on need and scale of analyses. We provide suggested terminology and notation style for this cross-over application of a specialized watershed algorithm. Among other possible applications, the resulting segmented, binned and agglomeration units offer alternatives to existing patch analysis methods for drawing relationships between patterns of urban development and ecological or environmental attributes.
