    Transitioning to Quality Education focuses on the fourth UN Sustainable Development Goal. According to SDG 4, every learner should acquire the knowledge and skills needed to promote sustainable development (UN 2015, 17). Thus, the aim of sustainability education is to foster learners to be creative and responsible global citizens, who critically reflect on the ideas of sustainable development and the values that underlie them, and take responsible actions for sustainable development (UNESCO 2017). Sustainability is strongly connected to attitudes and values, therefore, applications of sustainability are complicated. Quality education requires teachers to have competences, knowledge, and skills to be able to plan and carry out meaningful education and teaching in sustainability. The aim of Transitioning to Quality Education is to provide versatile experiences and new knowledge on the cognitive, affective, and social issues that are important for promoting sustainable development in formal and non-formal education. Transitioning to Quality Education is part of MDPI's new Open Access book series Transitioning to Sustainability. With this series, MDPI pursues environmentally and socially relevant research which contributes to efforts toward a sustainable world. Transitioning to Sustainability aims to add to the conversation about regional and global sustainable development according to the 17 SDGs. Set to be published in 2020/2021, the book series is intended to reach beyond disciplinary, even academic boundaries

    The international concept of food security is a situation where all people have physical, social, and economic access at all times to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life. All four parameters (availability, access, utilization, and stability) should therefore be measured to determine food security status.Taking into account these premises, this book aims to present original research articles and reviews concerning the following: Agriculture and food security; Agri-tourism and its potential to assist with food security; Business–science cooperation to advance food security; Competing demands and tradeoffs for land and water resources; Consumer behavior, nutritional security and food assistance programs; Food and health; Global and local analyses of food security and its drivers; Global governance and food security; Infectious and non-infectious diseases and food security; Reducing food loss and waste; Reducing risks to food production and distribution from climate change; Supply chains and food security; Technological breakthroughs to help feed the globe; Tourism food security relationship; Urbanization, food value chains, and the sustainable, secure sourcing of food; Food and service quality at food catering establishments; Consumer behavior at foodservice operations (restaurants, cafés, hotels)

    The Special Issue “Atmospheric Heavy Metal and Nitrogen Deposition Using Mosses as Biomonitors” includes a collection of papers related on aspects of passive moss biomonitoring of air quality in various regions of the world regarding the pollution sources of potentially toxic elements, heavy metal air pollution in the lockdown period due to the COVID-19 pandemic, trends in element atmospheric deposition, and relevance for ecological integrity and human health. Most of the studies were carried out in the framework of the International Cooperative Program on Effects of Air Pollution on Natural Vegetation and Crops (ICP Vegetation) of the United Nations Economic Commission for Europe (UNECE)

    Optimising acoustic cavitation for industrial application

    The ultrasonic horn is one of the most commonly used acoustic devices in laboratories and industry. For its efficient application to cavitation mediated process, the cavitation generated at its tip as a function of its tip-vibration amplitudes still needed to be studied in detail. High-speed imaging and acoustic detection are used to investigate the cavitation generated at the tip of an ultrasonic horn, operating at a fundamental frequency, f0, of 20 kHz. Tip-vibration amplitudes are sampled at fine increments across the range of input powers available. The primary bubble cluster under the tip is found to undergo subharmonic periodic collapse, with concurrent shock wave emission, at frequencies of f0/m, with m increasing through integer values with increasing tip-vibration amplitude. The contribution of periodic shock waves to the noise spectra of the acoustic emissions is confirmed. Transitional input powers for which the value of m is indistinct, and shock wave emission irregular and inconsistent, are identified through Vrms of the acoustic detector output. For cavitation applications mediated by bubble collapse, sonications at transitional powers may lead to inefficient processing. The ultrasonic horn is also deployed to investigate the role of shock waves in the fragmentation of intermetallic crystals, nominally for ultrasonic treatment of Aluminium melt, and in a novel two-horn configuration for potential cavitation enhancement effects. An experiment investigating nitrogen fixation via cavitation generated by focused ultrasound exposures is also described. Vrms from the acoustic detector is again used to quantify the acoustic emissions for comparison to the sonochemical nitrite yield and for optimisation of sonication protocols at constant input energy. The findings revealed that the acoustic cavitation could be enhanced at constant input energy through optimisation of the pulse duration and pulse interval. Anomalous results may be due to inadequate assessment for the nitrate generated. The studies presented in this thesis have illustrated means of improving the cavitation efficiency of the used acoustic devices, which may be important to some selected industrial processes

    Mastery Motivation and Executive Functions as School Readiness Factors: Enhancement of School Readiness in Kenya

    Get PDF
    The overall goal of this study is to enhance school readiness assessment in Kenya by developing an easy-to-use tablet-based android app that can support teachers and learners during the assessment of Pre-academic skills, Mastery Motivation (MM) and Executive Functions (EF) in the Kenyan context. We operationalised MM and EF as components of Approaches to Learning (ATL): one of the poorly assessed domains of school readiness. This research was based on the theory of ATL and followed a non-experimental longitudinal research design. One study was a Scoping Review that identified the gap in the literature in the assessment of School Readiness domains using game-like apps. This study formed the basis for developing Finding Out Children's Unique Strengths (FOCUS) app for Kenya following Education Design Research Approach. Two studies tested and evaluated the psychometric properties of the FOCUS app in the Kenyan context. Another two empirical studies focused on adapting the Preschool Dimension of Mastery Questionnaire 18 (DMQ 18) and the Childhood Executive Functioning (CHEXI) to complement the assessment of MM and EF, respectively. In addition, one study addressed the role played by MM and EF on school academic performance. A total of 40 teachers, 497 preschool and 535 grade 1 children were involved in this study. Both parametric and non-parametric statistical analyses were used to analyse the generated data. The FOCUS app, CHEXI and DMQ 18 fit well with the data and exhibited strong psychometric properties, thus being suitable for the Kenyan context. Furthermore, both MM and EF were directly and indirectly, involved in grade one children's academic performance. FOCUS app tasks, pre-academic skills, and number and letter search tasks at preprimary II strongly predicted preschool and grade one academic performance. MM assessed using the FOCUS app as a better predictor of academic performance than the DMQ 18. Interventions to improve MM and EF promise to enhance School Readiness in the Kenyan context. The FOCUS app can greatly complement Kenya School Readiness Test to give teachers and parents a broader spectrum to make correct decisions concerning the child
