    A Painter\u27s Brush That Also Makes Poems : Contemporary Painting After Northern Song Calligraphy

    There is no Western equivalent to the practice of calligraphy in pre-modern China, an aesthetic form which does not resolve itself into a literary object or a visual one. Calligraphy was sustained by a rich and complex body of thought that can fully rival art criticism and theory in the West. To undertake this project, I immersed myself in the study of both key works of calligraphy and the aesthetic that sustained it during the Northern Song dynasty (960-1127) in China—not in order to practice calligraphy but to transform my own understanding of art and make contemporary Western paintings out of that immersion. Various elements of that aesthetic are studied. Among them are the relation of the Chinese writing system to the natural world; the belief that calligraphy displays the writer’s character; the role of calligraphy in sustaining social relationships; calligraphy’s particular temporality; its political role during the Northern Song; the belief that the different arts of the brush could be transmuted into each other; and its relation to the past. After outlining the Northern Song aesthetic, I examine two canonical works of calligraphy: Su Shi’s scroll, Rain on the Festival of Cold Food, and Huang Tingjian’s Scroll for Zhang Datong. Following this, my own practice is examined in one recent painting, The Declining Year at Hangzhou. This leads into a wider, fragmentary discussion of the influence of the Northern Song aesthetic in relation to contemporary practice. As a result of this immersion, art is understood as a form of conduct rather than as a subjective expression

    The genetic heterogeneity and mutational burden of engineered melanomas in zebrafish models.

    BACKGROUND: Melanoma is the most deadly form of skin cancer. Expression of oncogenic BRAF or NRAS, which are frequently mutated in human melanomas, promote the formation of nevi but are not sufficient for tumorigenesis. Even with germline mutated p53, these engineered melanomas present with variable onset and pathology, implicating additional somatic mutations in a multi-hit tumorigenic process. RESULTS: To decipher the genetics of these melanomas, we sequence the protein coding exons of 53 primary melanomas generated from several BRAF(V600E) or NRAS(Q61K) driven transgenic zebrafish lines. We find that engineered zebrafish melanomas show an overall low mutation burden, which has a strong, inverse association with the number of initiating germline drivers. Although tumors reveal distinct mutation spectrums, they show mostly C > T transitions without UV light exposure, and enrichment of mutations in melanogenesis, p53 and MAPK signaling. Importantly, a recurrent amplification occurring with pre-configured drivers BRAF(V600E) and p53-/- suggests a novel path of BRAF cooperativity through the protein kinase A pathway. CONCLUSION: This is the first analysis of a melanoma mutational landscape in the absence of UV light, where tumors manifest with remarkably low mutation burden and high heterogeneity. Genotype specific amplification of protein kinase A in cooperation with BRAF and p53 mutation suggests the involvement of melanogenesis in these tumors. This work is important for defining the spectrum of events in BRAF or NRAS driven melanoma in the absence of UV light, and for informed exploitation of models such as transgenic zebrafish to better understand mechanisms leading to human melanoma formation

    Barriers and facilitators to using NHS Direct: a qualitative study of ‘users’ and ‘non-users’

    Background NHS Direct, introduced in 1998, has provided 24/7 telephone-based healthcare advice and information to the public in England and Wales. National studies have suggested variation in the uptake of this service amongst the UK¿s diverse population. This study provides the first exploration of the barriers and facilitators that impact upon the uptake of this service from the perspectives of both `users¿ and `non- users¿. Methods Focus groups were held with NHS Direct `users¿ (N?=?2) from Bedfordshire alongside `non-users¿ from Manchester (N?=?3) and Mendip, Somerset (N?=?4). Each focus group had between five to eight participants. A total of eighty one people aged between 21 and 94 years old (M: 58.90, SD: 22.70) took part in this research. Each focus group discussion lasted approximately 90 minutes and was audiotape-recorded with participants¿ permission. The recordings were transcribed verbatim. A framework approach was used to analyse the transcripts. Results The findings from this research uncovered a range of barriers and facilitators that impact upon the uptake of NHS Direct. `Non-users¿ were unaware of the range of services that NHS Direct provided. Furthermore, `non-users¿ highlighted a preference for face-to face communication, identifying a lack of confidence in discussing healthcare over the telephone. This was particularly evident among older people with cognitive difficulties. The cost to telephone a `0845¿ number from a mobile was also viewed to be a barrier to access NHS Direct, expressed more often by `non-users¿ from deprived communities. NHS Direct `users¿ identified that awareness, ease of use and convenience were facilitators which influenced their decision to use the service. Conclusions An understanding of the barriers and facilitators which impact on the access and uptake of telephone-based healthcare is essential to move patients towards the self-care model. This research has highlighted the need for telephone-based healthcare services to increase public awareness; through the delivery of more targeted advertising to promote the service provision availabl

    The ATLAS inner detector trigger performance in pp collisions at 13 TeV during LHC Run 2

    The design and performance of the inner detector trigger for the high level trigger of the ATLAS experiment at the Large Hadron Collider during the 2016-18 data taking period is discussed. In 2016, 2017, and 2018 the ATLAS detector recorded 35.6 fb−1^{-1}, 46.9 fb−1^{-1}, and 60.6 fb−1^{-1} respectively of proton-proton collision data at a centre-of-mass energy of 13 TeV. In order to deal with the very high interaction multiplicities per bunch crossing expected with the 13 TeV collisions the inner detector trigger was redesigned during the long shutdown of the Large Hadron Collider from 2013 until 2015. An overview of these developments is provided and the performance of the tracking in the trigger for the muon, electron, tau and bb-jet signatures is discussed. The high performance of the inner detector trigger with these extreme interaction multiplicities demonstrates how the inner detector tracking continues to lie at the heart of the trigger performance and is essential in enabling the ATLAS physics programme

    Análisis de las estadísticas oficiales del suicidio en España (1910-2011)

    En este trabajo se muestra la evolución histórica de las tasas de suicidio en España desde 1910 hasta 2011. Como novedad se presentan las tasas de suicidio estandarizadas, lo que las hace perfectamente comparables geográfica y temporalmente, ya que no se ven afectadas por la estructura de la población. Utilizando datos históricos de una serie de variables socioeconómicas para todas las provincias y aplicando novedosas técnicas estadísticas de análisis de panel de datos, hemos podido confirmar muchas de las hipótesis establecidas por Durkheim a finales del siglo XIX, especialmente las relacionadas con el nivel de fecundidad y nupcialidad, la edad, el sexo y el índice de envejecimiento. También hemos contradicho los planteamientos del sociólogo francés en lo referente al impacto del proceso de urbanización y la pobreza sobre el suicidio.In this article we examine the evolution of suicide rates in Spain from 1910 to 2011. As something new, we use standardised suicide rates, making them perfectly comparable geographically and in time, as they no longer reflect population structure. Using historical data from a series of socioeconomic variables for all Spain's provinces and applying new techniques for the statistical analysis of panel data, we are able to confirm many of the hypotheses established by Durkheim at the end of the 19th century, especially those related to fertility and marriage rates, age, sex and the aging index. Our findings, however, contradict Durkheim's approach regarding the impact of urbanisation processes and poverty on suicide
