Description:
This book examines the nuanced and situated experiences of self-study researchers. It explores the ways in which ethics are dynamic, idiosyncratic and require an ongoing ethical reflexivity. In addition, the book identifies, documents and collates the collective experiences of self-study researchers and sheds new light on the role and impact of ethics, ethical dilemmas and ensuing decisions for education researchers. The book considers the ethical dilemmas that self-study researchers in teacher education face, their careful ethical considerations while conducting research, and how they form their professional judgment and understanding of what it means to be an ethical self-study researcher. For self-study researchers, there are a number of ethical dilemmas and challenges that cannot be neatly captured by the frameworks and guidelines of an ethics board. For many, this requires researchers to be ever-present and re-engaged with the ethics of their own projects, from the development, through to the dissemination of their work. Readers will gain a deeper understanding of ethics, ethical perspectives and practices in the field of self-study research.

The adapted Autobiographical Interview (AI) is one of the most commonly used and widely cited measures of prospection in adult humans. The use of this instrument requires investigators to make many decisions that can influence the outcomes of studies. Here, we performed a systematic review of studies utilizing the adapted AI. We assessed and characterized the studies on various aspects of methodological quality and reporting. We then investigated and reported on several properties of adapted AI scores that have implications for their interpretation. We conclude by proposing Conduct and Reporting of Autobiographical Interview (CRAI) guidelines to contribute to the improvement of the reporting quality for studies that use the adapted AI, and hope that this will contribute to future efforts to validate this influential measurement instrument of prospection in humans.

This article critiques the Indian material culture located in present-day Pakistan pertaining to the inaugural Australian cricket tour to colonial India in 1935/36. The historical voice of the Indians is evident in the images and it is over the shoulders of the hosts of the tour that new perspectives emerge. It is culturally inappropriate to assume and evaluate how the locals felt about the visit of the Australian cricketers and the raison d’être of the tour. However, archives located in Pakistan provide a deeply subjective perspective. Goodwill and amicability reverberate through the photographs challenging conventional scholarship, which argues that Australian-Indian cricket is based on acrimony. The article concludes that despite the obvious and significant differences between the competing teams the tour experience minimized the racial divide between the Australian and the Indian cricketers.

Recently, street furniture, including bins, seats, and bus shelters, has become smart as it has been equipped with environmental sensors, wireless modules, processors, and microcontrollers. Accordingly, smart furniture is expected to become a vital part of the IoT infrastructure and one of the drivers of future smart cities. This work focuses on how smart street furniture can be exploited within the IoT architecture as a basis of recommender systems, toward achieving smart cities' different components. We present and discuss recent relevant work as well as the key challenges and opportunities for future research. We explain that much work is still required when it comes to combining scalability, real-time processing, smart furniture, and recommender systems.

It was conjectured by Demyanov and Ryabova (Discrete Contin Dyn Syst 31(4):1273–1292, 2011) that the minimal cycle in the sequence obtained via repeated application of the Demyanov converter to a finite family of polytopes is at most two. We construct a counterexample for which the minimal cycle has length 4.

The Douglas–Rachford algorithm is a popular algorithm for solving both convex and nonconvex feasibility problems. While its behaviour is settled in the convex inconsistent case, the general nonconvex inconsistent case is far from being fully understood. In this paper, we focus on the most simple nonconvex inconsistent case: when one set is a hyperplane and the other a doubleton (i.e., a two-point set). We present a characterization of cycling in this case which—somewhat surprisingly—depends on whether the ratio of the distance of the points to the hyperplane is rational or not. Furthermore, we provide closed-form expressions as well as several concrete examples which illustrate the dynamical richness of this algorithm.

Purpose: The purpose of this paper is to explore the drivers of economic growth in South Asia region for the period of 1975–2016 using the World Bank data. Design/methodology/approach: Panel corrected standard error (static estimation) approach and one-step system generalised method of moments (dynamic estimation) approach are used. Findings: Both the static and dynamic estimations indicate that energy use, gross capital formation and remittances are the main drivers of economic growth in South Asian countries. The effects of all these variables are positive and significant. The extent of the effect of energy use is much higher than that of other two variables on the economic growth. A 1 per cent increase in the growth of energy consumption can expedite the gross domestic product growth by approximately 3 per cent in South Asia. However, the key variables, such as trade, government expenditure and foreign direct investment demonstrate no significant effect. Originality/value: The current research is original in the sense that it investigated the issue with a new data set using improved econometric techniques. Moreover, in South Asia as a whole, this kind of study is totally absent, particularly with panel data of a large number of years. Furthermore, this study has taken into account the problem of heterogeneity and the biases created by cross-section dependence, which were mostly absent in previous studies. Therefore, the findings of this research are new contributions to the existing literature.

Background: Children with enhanced fundamental movement skills may benefit from improved physical, social and psychological development, resulting in an increased likelihood of an active lifestyle in later years. Aim: We investigated the effects of a nine-week, child-centred, physical activity programme on cognitive and motor skills in typically developing 12 - 24-month-old toddlers. Methods: In a randomised control trial, 90 toddlers (age 17.0 ± 2.6 months; 52.2% male) were split into two groups stratified by age and sex. The intervention completed was either nine weeks of one-hour per week physical activity classes (n = 45; EXP) or normal physical activity (n = 45; control). Prior to and following the intervention period, safety skills (nine-skill test battery), anthropometric measures (mass and height), motor and cognitive development (Bayley Scales of Infant Development) were assessed. Results: EXP improved overall safety skills score (P = 0.04), toddlers’ abilities to climb over a small-runged A-frame while using a cylinder grip and safe face-the-slope dismount (P = 0.001), and the execution of a safety roll down a foam wedge (P = 0.02). Improvements in development as measured by the Bayley’s Scales were attributed to typical development rather than the intervention. Conclusions: A 9-week, physical activity programme improved toddlers’ safety skills but not overall cognitive or motor development.

Description:
Stabilization procedures affect nutrient and inorganic contaminant concentrations.•Anaerobic sludge has the highest levels of metals and radionuclides.•High P and N contents in sludge are a measure of its potential as a fertilizer.•Adsorption of metals and radionuclides to sludge biomass increases with nutrient content.•Soil amendment with sewage sludge is a promising strategy for nutrient recovery. This study assesses the potential use of different types of stabilized sewage sludge as a soil amendment by considering their physicochemical characteristics, nutritional status, and their trace metal and radionuclide content. The concentrations of trace metals and radionuclides were determined using ICP-OES and gamma-ray spectrometry, respectively. For determining nutritional status and chemical characterization, this study followed standard ISO-recommended procedures. Data analysis revealed that anaerobic sludge contains higher concentrations of Cr, Hg, and Ni compared to aerobic and non-biologically stabilized sludge. A similar observation was observed in the case of 226Ra, 210Pb, 228Ra, and 228Th. Furthermore, the high levels of P and N in aerobic sludge suggest that biologically stabilized sludge has the potential to be a good fertilizer. In addition, the study finds strong evidence that nutrients are involved in the adsorption of metals and radionuclides onto sludge biomass. Overall, eight of the nine studied sludge samples are safe for agricultural use since the concentrations of trace metals fall well below the limits set by Croatian legislation (NN 38/08). In addition, the levels of radionuclides do not pose a radiological risk. This means that soil conditioning with sewage sludge remains a viable strategy for nutrient recovery from municipal waste, although long-term impact assessments of repeated applications are necessary.
Description:
Effects of different boundary conditions prescribed across the boundaries of radiofrequency ablation (RFA) models of liver cancer are investigated for the case where the tumour is at the liver boundary. Ground and Robin-type conditions (electrical field) and body temperature and thermal insulation (thermal field) conditions are examined. 3D models of the human liver based on publicly-available CT images of the liver are developed. An artificial tumour is placed inside the liver at the boundary. Simulations are carried out using the finite element method. The numerical results indicated that different electrical and thermal boundary conditions led to different predictions of the electrical potential, temperature and thermal coagulation distributions. Ground and body temperature conditions presented an unnatural physical conditions around the ablation site, which results in more intense Joule heating and excessive heat loss from the tissue. This led to thermal damage volumes that are smaller than the cases when the Robin type or the thermal insulation conditions are prescribed. The present study suggests that RFA simulations in the future must take into consideration the choice of the type of electrical and thermal boundary conditions to be prescribed in the case where the tumour is located near to the liver boundary.
