Novel colours and the content of experience

I propose a counterexample to naturalistic representational theories of phenomenal character. The counterexample is generated by experiences of novel colours reported by Crane and Piantanida. I consider various replies that a representationalist might make, including whether novel colours could be possible colours of objects and whether one can account for novel colours as one would account for binary colours or colour mixtures. I argue that none of these strategies is successful and therefore that one cannot fully explain the nature of the phenomenal character of perceptual experiences using a naturalistic conception of representation

British Society of Gastroenterology Best Practice Guidance: outpatient management of cirrhosis - part 3: special circumstances

\ua9 2023 BMJ Publishing Group. All rights reserved.The prevalence of cirrhosis has risen significantly over recent decades and is predicted to rise further. Widespread use of non-invasive testing means cirrhosis is increasingly diagnosed at an earlier stage. Despite this, there are significant variations in outcomes in patients with cirrhosis across the UK, and patients in areas with higher levels of deprivation are more likely to die from their liver disease. This three-part best practice guidance aims to address outpatient management of cirrhosis, in order to standardise care and to reduce the risk of progression, decompensation and mortality from liver disease. Part 1 addresses outpatient management of compensated cirrhosis: screening for hepatocellular cancer, varices and osteoporosis, vaccination and lifestyle measures. Part 2 concentrates on outpatient management of decompensated disease including management of ascites, encephalopathy, varices, nutrition as well as liver transplantation and palliative care. In this, the third part of the guidance, we focus on special circumstances encountered in managing people with cirrhosis, namely surgery, pregnancy, travel, managing bleeding risk for invasive procedures and portal vein thrombosis

This three-part best practice guidance aims to address outpatient management of cirrhosis, in order to standardise care and to reduce the risk of progression, decompensation and mortality from liver disease. Here, in part one, we focus on outpatient management of compensated cirrhosis, encompassing hepatocellular cancer surveillance, screening for varices and osteoporosis, vaccination and lifestyle measures. We also introduce a compensated cirrhosis care bundle for use in the outpatient setting.

Generation tourism: towards a common identity

The purpose of this article is to highlight the implications of the indiscipline of tourism academia for a new generation of tourism academics. Generation Tourism is characterised by scholars with a multi-disciplinary education associated with a broad field of study and commonly considered to lack the advantages of a discipline-focused education with its strong theoretical and methodological foundations. The problem this article addresses relates to how new generations of scholars and their views on knowledge creation achieve ascendancy in ways that move on from existing paradigms and earlier cohorts of scholars. Our main argument is that Generation Tourism scholars would benefit from a more clearly developed and common academic identity. To begin the critical conversation around the identity of Generation Tourism we outline five possible points of departure. These points are: (1) learning from historical developments in parent disciplines; (2) spearheading inter-disciplinary scholarship; (3) working towards theoretical developments; (4) embracing mediating methodologies and (5) forming tourism nodes and networks. Recognising these as starting points rather than final statements, we hope that the conversation about Generation Tourism identity will continue in other forums

Taking a hike: Exploring leisure walkers embodied experiences

This paper uses walk along interviewing to investigate embodied experiences of walking on the South Downs Way, a long distance trail in southern England. Using a qualitative methodology - encompassing 93 walk-along interviews and auto-ethnographic reflections of two walker/researchers - it explores how walkers conceptualise their own walking experiences and captures this information while they are walking. It contributes to and extends the emerging body of literature which explores people’s experience, specifically aiming to develop a deeper understanding of leisure walking experiences in the dynamic space of the walk. It examines a range of bodily sensations and emotional states associated with the leisure walking experience in the context of temporal and environmental aspects, identifying those feelings that are innate and those which are mediated by external conditions. Current experiences intertwine with memories of other places and times in a process where connections are made between mind, body, the immediate physical environment, self and others, and disconnections from everyday life and the wider environment. These connections and disconnections create a sense of perspective, achievement and well-being

Search for CP Violation in the Decay Z -> b (b bar) g

About three million hadronic decays of the Z collected by ALEPH in the years 1991-1994 are used to search for anomalous CP violation beyond the Standard Model in the decay Z -> b \bar{b} g. The study is performed by analyzing angular correlations between the two quarks and the gluon in three-jet events and by measuring the differential two-jet rate. No signal of CP violation is found. For the combinations of anomalous CP violating couplings, ${\hat{h}}_b = {\hat{h}}_{Ab}g_{Vb}-{\hat{h}}_{Vb}g_{Ab}$ and $h^{\ast}_b = \sqrt{\hat{h}_{Vb}^{2}+\hat{h}_{Ab}^{2}}$, limits of \hat{h}_b < 0.59$and$h^{\ast}_{b} < 3.02$ are given at 95\% CL.Comment: 8 pages, 1 postscript figure, uses here.sty, epsfig.st

Single hadron response measurement and calorimeter jet energy scale uncertainty with the ATLAS detector at the LHC

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of sqrt(s) = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of K_s and Lambda particles, the calorimeter response to specific types of particles (positively and negatively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral particles to jets. The response uncertainty is 2-5% for central isolated hadrons and 1-3% for the final calorimeter jet energy scale.Comment: 24 pages plus author list (36 pages total), 23 figures, 1 table, submitted to European Physical Journal

Search for the glueball candidates f0(1500) and fJ(1710) in gamma gamma collisions

Data taken with the ALEPH detector at LEP1 have been used to search for gamma gamma production of the glueball candidates f0(1500) and fJ(1710) via their decay to pi+pi-. No signal is observed and upper limits to the product of gamma gamma width and pi+pi- branching ratio of the f0(1500) and the fJ(1710) have been measured to be Gamma_(gamma gamma -> f0(1500)). BR(f0(1500)->pi+pi-) < 0.31 keV and Gamma_(gamma gamma -> fJ(1710)). BR(fJ(1710)->pi+pi-) < 0.55 keV at 95% confidence level.Comment: 10 pages, 3 figure
