Living with MĂ©niĂšre\u27s Disease: Understanding Patient Experiences of Mental Health and Well-Being in Everyday Life
This chapter will discuss the current knowledge of the mental health and wellbeing impact of MĂ©niĂšreâs. To date, our understanding is limited, with small sample sizes, no controls, and the inability to account for confounding factors. Our work in the UK Biobank aimed to further our understanding of the impacts of MĂ©niĂšreâs at the population level
Traditional tales and imaginary contexts in primary design and technology: a case study.
Working with contexts is a key component to design and technology activity and education. The most recent iteration of the national curriculum programme of study for design and technology, in England, sets out that children between the ages of 5 and 7 ?should work in a range of relevant contexts? (DfE, 2013: 193); suggested contexts including ?home and school, gardens and playgrounds, the local community, industry and the wider environment?. Whilst these are real world and familiar contexts, fictional contexts also provide opportunities for developing ?creative spaces? in which to speculate and discuss. This intrinsic case study explores the work of two primary teachers? development of a design and technology activity, where traditional tales provide the context. Children explore design problems and opportunities through the eyes of the Billy Goats Gruff, as they seek assistance to cross the river. Data was gathered through semistructured interviews and document analysis of children?s design work. The case study reveals how multidisciplinary and imaginative approaches to teaching and learning in the primary classroom simulate and nurture design thinking, dialogue and critique

Understanding the Changing Cultural Value of the BBC World Service and the British Council
This project investigated the changing cultural value of the BBC World Service (WS) and the British Council (BC) and how their cultural value can be assessed and measured. For eight decades, these organisations have been the face and voice of Britain overseas. Our research found that their attraction and influence abroad remains strong, but is on the wane, reflecting the UKâs declining economic and political significance on the world stage.
Among the key findings of our historical and contemporary research: Cultural value is the catalyst of all aspects of value at WS and BC, founded on their capacity to act as transcultural intermediaries, fostering international understanding, and setting benchmarks in global standards for journalism and cultural relations work. Cultural value is relational, never independent of political and economic value. It is perspectival: audiences trust the quality and credibility of outputs; high professional standards and prestige benefit staff; funders appreciate the diplomatic and soft power assets. Cultural value accrues slowly over time but can be quickly lost.
Social media afford new ways of connecting, informing and engaging citizens at home and abroad. Our case studies analysing the uses of Twitter and Facebook by BC and WS around global media events underscore the so far limited role of social media in democratising participation and promoting intercultural dialogue.
We developed an innovative, theoretically grounded and empirically informed Cultural Value Model (CVM). This is an innovative device for conceptualising, analysing and assessing value in a multidimensional, composite, visual way. The CVM is designed for planning, monitoring and evaluating projects and organisations over time, alongside existing performance indicators and impact measures. It is currently being tested and developed on further projects at WS and BC as well as at the Swedish Institute

A long-term perspective on a modern drought in the American Southeast
The depth of the 2006-9 drought in the humid, southeastern US left several metropolitan areas with only a 60-120 day water supply. To put the region's recent drought variability in a long-term perspective, a dense and diverse tree-ring networkâincluding the first records throughout the Apalachicola-Chattahoochee-Flint river basinâis used to reconstruct drought from 1665 to 2010 CE. The network accounts for up to 58.1% of the annual variance in warm-season drought during the 20th century and captures wet eras during the middle to late 20th century. The reconstruction shows that the recent droughts are not unprecedented over the last 346 years. Indeed, droughts of extended duration occurred more frequently between 1696 and 1820. Our results indicate that the era in which local and state water supply decisions were developed and the period of instrumental data upon which it is based are amongst the wettest since at least 1665. Given continued growth and subsequent industrial, agricultural and metropolitan demand throughout the southeast, insights from paleohydroclimate records suggest that the threat of water-related conflict in the region has potential to grow more intense in the decades to come
The LOFAR Transients Pipeline
Current and future astronomical survey facilities provide a remarkably rich
opportunity for transient astronomy, combining unprecedented fields of view
with high sensitivity and the ability to access previously unexplored
wavelength regimes. This is particularly true of LOFAR, a
recently-commissioned, low-frequency radio interferometer, based in the
Netherlands and with stations across Europe. The identification of and response
to transients is one of LOFAR's key science goals. However, the large data
volumes which LOFAR produces, combined with the scientific requirement for
rapid response, make automation essential. To support this, we have developed
the LOFAR Transients Pipeline, or TraP. The TraP ingests multi-frequency image
data from LOFAR or other instruments and searches it for transients and
variables, providing automatic alerts of significant detections and populating
a lightcurve database for further analysis by astronomers. Here, we discuss the
scientific goals of the TraP and how it has been designed to meet them. We
describe its implementation, including both the algorithms adopted to maximize
performance as well as the development methodology used to ensure it is robust
and reliable, particularly in the presence of artefacts typical of radio
astronomy imaging. Finally, we report on a series of tests of the pipeline
carried out using simulated LOFAR observations with a known population of
transients.Comment: 30 pages, 11 figures; Accepted for publication in Astronomy &

Identifying transient and variable sources in radio images
With the arrival of a number of wide-field snapshot image-plane radio transient surveys, there will be a huge influx of images in the coming years making it impossible to manually analyse the datasets. Automated pipelines to process the information stored in the images are being developed, such as the LOFAR Transients Pipeline, outputting light curves and various transient parameters. These pipelines have a number of tuneable parameters that require training to meet the survey requirements. This paper utilises both observed and simulated datasets to demonstrate different machine learning strategies that can be used to train these parameters. We use a simple anomaly detection algorithm and a penalised logistic regression algorithm. The datasets used are from LOFAR observations and we process the data using the LOFAR Transients Pipeline; however the strategies developed are applicable to any light curve datasets at different frequencies and can be adapted to different automated pipelines. These machine learning strategies are publicly available as PYTHON tools that can be downloaded and adapted to different datasets (https://github.com/AntoniaR/TraP_ML_tools)
Pre-Conceptual Design of a Fluoride-Salt-Cooled Small Modular Advanced High Temperature Reactor (SmAHTR)
This document presents the results of a study conducted at Oak Ridge National Laboratory during 2010 to explore the feasibility of small modular fluoride salt-cooled high temperature reactors (FHRs). A preliminary reactor system concept, SmATHR (for Small modular Advanced High Temperature Reactor) is described, along with an integrated high-temperature thermal energy storage or salt vault system. The SmAHTR is a 125 MWt, integral primary, liquid salt cooled, coated particle-graphite fueled, low-pressure system operating at 700 C. The system employs passive decay heat removal and two-out-of-three , 50% capacity, subsystem redundancy for critical functions. The reactor vessel is sufficiently small to be transportable on standard commercial tractor-trailer transport vehicles. Initial transient analyses indicated the transition from normal reactor operations to passive decay heat removal is accomplished in a manner that preserves robust safety margins at all times during the transient. Numerous trade studies and trade-space considerations are discussed, along with the resultant initial system concept. The current concept is not optimized. Work remains to more completely define the overall system with particular emphasis on refining the final fuel/core configuration, salt vault configuration, and integrated system dynamics and safety behavior
Male Choice in the Stream-Anadromous Stickleback Complex
Studies of mating preferences and pre-mating reproductive isolation have often focused on females, but the potential importance of male preferences is increasingly appreciated. We investigated male behavior in the context of reproductive isolation between divergent anadromous and stream-resident populations of threespine stickleback, Gasterosteus aculeatus, using size-manipulated females of both ecotypes. Specifically, we asked if male courtship preferences are present, and if they are based on relative body size, non-size aspects of ecotype, or other traits. Because male behaviors were correlated with each other, we conducted a principal components analysis on the correlations and ran subsequent analyses on the principal components. The two male ecotypes differed in overall behavioral frequencies, with stream-resident males exhibiting consistently more vigorous and positive courtship than anadromous males, and an otherwise aggressive behavior playing a more positive role in anadromous than stream-resident courtship. We observed more vigorous courtship toward smaller females by (relatively small) stream-resident males and the reverse pattern for (relatively large) anadromous males. Thus size-assortative male courtship preferences may contribute to reproductive isolation in this system, although preferences are far from absolute. We found little indication of males responding preferentially to females of their own ecotype independent of body size
