Prediction of outdoor ground effect
No full textA classification of outdoor ground surfaces for calculating the attenuation due to destructive interference between direct and ground-reflected sound is proposed which uses a physically admissible ground impedance model with parameters of porosity, flow resistivity, and, for some ground surfaces, layer depth. This impedance model is shown to enable good fits to short range level difference measurements over a wide range of ground surfaces. Ranges of parameter values are suggested in each class to allow for variations in soil depth profiles, moisture content and surface roughness. Also, methods are proposed to account for mean ground roughness heights of less than 0.1 m and for waves on a water surface. The influence of atmospheric turbulence on ground effect is included through a coherence factor which assumes a Kolmogorov turbulence spectrum with parameters for which values can be calculated if heat flux and friction velocity are known. To account for changes in impedance along the propagation path, a Fresnel zone method is proposed which weights pressures squared since this method has been shown to compare better with 2D Boundary Element Method predictions than a method that weights excess attenuation
How Ed Tech could help to make us (become) healthier
No full textWe live in unprecedented times where never before in history are we able to scientifically link health outcomes to health choices we all make as individuals, families and as societies. In any high street or supermarket there are endless choices of food and drink available to buy. With unprecedented levels of ready-prepared meals and ‘ fast’ foods sometimes one wonders why one would even consider to prepare and cook one’s own dinner. A nice anecdote when we first moved to the UK in our new home in 2010 was that the decorator who finished our kitchen in our rental house said: “You have an amazing kitchen with a fantastic stove, but you will probably never going to use that with so many take-away options in your neighbourhood!”
One reason to be critical towards what one eats and drinks and how one remains physically active is the increased evidence that most modern “Western” diseases linked to obesity, diabetes, and cardiovascular issues are all linked to the (un)conscious life-style choices we all make. With two thirds of UK adults being overweight or even obese, and numbers across the world rising to similar levels in the UK, one wonders how and why we ended up in this situation, and how we could reverse this trend (with Ed Tech)
Learning to Teach Music in the Secondary School: A Companion to School Experience (4th edition)
No full textThis fourth edition of Learning to Teach Music in the Secondary School has been thoroughly revised to reflect the latest changes, initiatives, research and scholarship in music education. By focusing on overarching principles, it aims to develop reflective practitioners who will creatively and critically examine their own and others’ ideas about music education.
The new edition seeks to prioritise understandings of young people’s musical lives—including their cultural experiences, digital competencies and individual needs—as the context in which to reflect on teaching and learning within and beyond the music classroom. Providing an overview of contemporary issues in music teaching and learning from a range of perspectives, this book focuses on teaching music musically and enables the reader to:
* place music education in its historical and social context;
consider the nature of musical knowledge and how teachers can facilitate young people's musical learning;
critically analyse the frameworks within which music teachers work;
* develop an understanding of composing, performing and responding to music, as well as key issues such as creativity, individual needs and assessment;
* examine aspects of music beyond the classroom and how effective links can be made between curriculum music and music outside school.
Including a range of case studies, tasks and reflections to help integrate the theory and practice of music education effectively, this new edition will provide valuable support, guidance and challenges for teachers at all stages of their careers, as well as being a useful resource for teacher educators in a wide range of settings
Instability in Ostwald Ripening Processe
No full textThere is a dimensionless parameter which enters into the equation for the evolution of supersaturation in Ostwald ripening processes. This parameter is typically a large number. Here it is argued that the consequent stiffness of the equation results in the evolution of the supersaturation being unstable. The instability is evident in numerical simulations of Ostwald ripening
Collaborative toolkit creation to support reflective practice in teacher education
No full textReflection in practice and on practice is a vital aspect of teacher education, especially in enabling student teachers to link theory and practice. However, student teachers’ perceptions of what reflection is, and how to reflect on their teaching, varies. Additionally, student teachers may often view reflective practice as a course requirement rather than a supportive tool to enable development of practice. This project aimed to support student teachers to develop confidence when reflecting on their practice by identifying features of effective reflection and considering approaches that they could adopt. This was achieved by developing a stronger understanding of the theoretical models that can support reflective practice and understanding the challenges experienced by student teachers. The participatory study involved eight student teachers and four teacher educators, with existing reflective models reviewed and trialled. Prior to an initial workshop, student teachers approached their reflective practice in a variety of ways. Some needed to write their reflections, whilst others felt that oral reflection and professional discussion supported them more effectively. Student teachers felt supported when they had a staged model to scaffold this process and were drawn towards reflective models with such structure. Drawing on their experiences, a toolkit has been co-created that offers student teachers an evidence-informed framework to assist with confident and effective reflective practice. Indicative findings show that reflecting on practice is a very personal choice. During the co-creation of the toolkit, the student teachers drew on features they had evaluated to be the most effective from existing models whilst allowing for personal tailoring of bespoke models. More than 200 student teachers on a blended teacher education programme will be introduced to the co-created toolkit and encouraged to use it to support confident and effective reflective practice

No full textCelebrating Women in Legal History: Making and Shaping a Discipline
No full textThis book champions the work of women in legal history, and their contributions to both the discipline and feminist activism over nearly two centuries.
It considers women in academia, which was, in theory, open to women before they could become lawyers in most European countries. And it considers women working beyond the academy: many studied legal history in other ways; in local history societies, through archival work, and via activism.
Women legal historians have been under-recognised or forgotten altogether, even where they made substantial scholarly contributions. In focusing on the work of women in legal history, this book lays the foundations for a transformational reassessment of the discipline. It asks searching questions about what counts as legal history. It demonstrates that work by and about women should appear in our legal history courses, be discussed in our seminars, and be cited in our academic work. If the field of legal history is lively, innovative, and wide-ranging, everyone working in it benefits. By shining a light on undervalued scholarship, and areas which have received insufficient attention, we challenge assumptions in our discipline and advance its methods.
Whilst some women were pioneers and worked to change gendered aspects of the law, others led more ordinary lives, disappearing from the gaze of legal history even as they contributed to it. This book tells some of their stories
How Accurately Can Obscured Galaxy Luminosities Be Measured Using Spectral Energy Distribution Fitting of Near- through Far-infrared Observations?
No full textInfrared-luminous galaxies are important sites of stellar and black hole mass assembly at most redshifts. Their luminosities are often estimated by fitting spectral energy distribution (SED) models to near- to far-infrared data, but the dependence of these estimates on the data used is not well understood. Here, using observations simulated from a well-studied local sample, we compare the effects of wavelength coverage, signal-to-noise ratio, flux calibration, angular resolution, and redshift on the recovery of starburst, active galactic nucleus (AGN), and host luminosities. We show that the most important factors are wavelength coverage that spans the peak in a SED, and dense wavelength sampling. Such observations recover starburst and AGN infrared luminosities with systematic bias below 20%. Starburst luminosities are best recovered with far-infrared observations, while AGN luminosities are best recovered with near- and mid-infrared observations, though the recovery of both are enhanced with near/mid-infrared and far-infrared observations, respectively. Host luminosities are best recovered with near/far-infrared observations, but are usually biased low, by ≳20%. The recovery of starburst and AGN luminosity is enhanced by observing at high angular resolution. Starburst-dominated systems show more biased recovery of luminosities than do AGN-dominated systems. As redshift increases, far-infrared observations become more capable and mid-infrared observations less capable at recovering luminosities. Our results highlight the transformative power of a far-infrared instrument with dense wavelength coverage, from tens to hundreds of microns, for studying infrared-luminous galaxies. We tabulate estimates of systematic bias and random error for use with JWST and other observatories
The Sociolinguistics of Dying, Death and Mourning: Remediating Practices of Language, Narrative, and Affect in Digital Contexts
No full textThis chapter starts by discussing consistent findings that have emerged from studies in the cross-disciplinary area of death online. Noting the lack of systematic attention to language and narrative in that area, it presents a sociolinguistic approach to remediations of death, dying and mourning in social media contexts. The approach draws on the empirical framework of sharing practices (Androutsopoulos 2014), small stories research (Georgakopoulou 2015) and affective positioning (Giaxoglou 2021). This approach provides a view of death, dying and mourning as tellable and narratable in local contexts, which are to be empirically investigated. In the second part of the chapter, an illustration of the approach is offered with a sample analysis of sharing practices, namely selecting, (small) storying, and positioning in the case of influential Instagram cancer vlogger, the late Dame Deborah James - also known online as Bowelbabe. The chapter concludes with remarks on the importance of situated sociolinguistic approaches to language and death for unpacking the diverse and constantly changing practices of dying, death and mourning in social media environments
