Working, travelling, and identity: J.B. Priestley’s English Journey (1934)

The motivation for travel is central to its form and content. This article addresses an under-represented area of travel writing: the travel text that results from a journey undertaken for work purposes. By considering J. B. Priestley’s English Journey as a case-study, it argues that the text’s critical reception, at first disorientated and confused, and later dominated by historical and political readings, has resulted from Priestley’s emphasis on work rather than leisure. In his text Priestley explores the relationship of work and identity, and his own position as writer and traveller is central to this, symbolised in his preoccupation with the figure of the travelling salesman

Ensemble evaluation of hydrological model hypotheses

It is demonstrated for the first time how model parameter, structural and data uncertainties can be accounted for explicitly and simultaneously within the Generalized Likelihood Uncertainty Estimation (GLUE) methodology. As an example application, 72 variants of a single soil moisture accounting store are tested as simplified hypotheses of runoff generation at six experimental grassland field-scale lysimeters through model rejection and a novel diagnostic scheme. The fields, designed as replicates, exhibit different hydrological behaviors which yield different model performances. For fields with low initial discharge levels at the beginning of events, the conceptual stores considered reach their limit of applicability. Conversely, one of the fields yielding more discharge than the others, but having larger data gaps, allows for greater flexibility in the choice of model structures. As a model learning exercise, the study points to a “leaking” of the fields not evident from previous field experiments. It is discussed how understanding observational uncertainties and incorporating these into model diagnostics can help appreciate the scale of model structural error

A qualitative study of the barriers to procedural sedation practices in paediatric emergency medicine in the UK and Ireland

© Published by the BMJ Publishing Group Limited. Introduction There is extensive literature on paediatric procedural sedation (PPS) and its clinical applications in emergency departments (EDs). While numerous guidance and policy documents exist from international bodies, there remains a lack of uniformity and consistency of PPS practices within EDs. PPS is now gaining traction in the UK and Ireland and this study aimed to describe existing PPS practices and identify any challenges to training and provision of ED-based PPS. Methods A qualitative approach was employed to capture data through a focus group interview. Nine consultants in emergency medicine (EM) participated, varying in years of experience, clinical settings (mixed adult and paediatric ED or paediatric only) and geographical location (UK and Ireland). The focus group was audio-recorded, transcribed verbatim and analysed using Attride-Stirling's framework for thematic network analysis. Results The global theme â € The Future of PPS in EM - A UK and Ireland Perspective' emerged from the following three organising themes: (1) training and education of ED staff; (2) current realities of PPS in EDs and (3) PPS and the wider hospital community. The main findings were (1) there is variability in ED PPS practice throughout the UK and Ireland; (2) lack of formal PPS training for trainees is a barrier to its implementation as a standard treatment and (3) there is a lack of recognition of PPS at a College level as a specialised EM skill. Conclusions Establishment of PPS as a standard treatment option in the emergency setting will require implementation of robust training into general and paediatric EM training. This should be supported and enhanced through national and international collaboration in EM-led PPS research and audit

Effect of historical changes in land use and climate on the water budget of an urbanizing watershed

The definitive version was published in Water Resources Research 42 (2006): W03426, doi:10.1029/2005WR004131.We assessed the effects of historical (1931-1998) changes in both land-use and climate on the water budget of a rapidly urbanizing watershed, Ipswich River basin (IRB), in northeastern Massachusetts. Water diversions and extremely low flow during summer are major issues in the IRB. Our study centers on a detailed analysis of diversions and a combined empirical/modeling treatment of evapotranspiration (ET) response to changes in climate and land-use. A detailed accounting of diversions showed that net diversions increased due to increases in water withdrawals (primarily ground water pumping) and export of sewage. Net diversions constitute a major component of runoff (20% of streamflow). Using a combination of empirical analysis and physically based modeling we related an increase in precipitation (2.7 mm/yr) and changes in other climate variables to an increase in ET (1.7 mm/yr). Simulations with a physically based water-balance model showed that the increase in ET could be attributed entirely to a change in climate, while the effect of land-use change was negligible. The land-use change effect was different from ET and runoff trends commonly associated with urbanization. We generalized these and other findings to predict future streamflow using climate change scenarios. Our study could serve as a framework for studying suburban watersheds, being the first study of a suburban watershed that addresses long-term effects of changes in both land-use and climate, and accounts for diversions and other unique aspects of suburban hydrology.This research was partially supported by NSF grants (DEB-9726862, OCE-9726921 and OCE-0423565)

Heterodyne mixing of millimetre electromagnetic waves and sub-THz sound in a semiconductor device

We demonstrate heterodyne mixing of a 94 GHz millimetre wave photonic signal, supplied by a Gunn diode oscillator, with coherent acoustic waves of frequency ~ 100 GHz, generated by pulsed laser excitation of a semiconductor surface. The mixing takes place in a millimetre wave Schottky diode, and the intermediate frequency electrical signal is in the 1 – 12 GHz range. The mixing process preserves all the spectral content in the acoustic signal that falls within the intermediate frequency bandwidth. Therefore this technique may find application in high-frequency acoustic spectroscopy measurements, exploiting the nanometre wavelength of sub-THz sound. The result also points the way to exploiting acoustoelectric effects in photonic devices working at sub-THz and THz frequencies, which could provide functionalities at these frequencies, e.g. acoustic wave filtering, that are currently in widespread use at lower (GHz) frequencies

Extension and Dynamics of the Andes inferred from the 2016 Parina (Huarichancara) Earthquake

The M w 6.1 2016 Parina earthquake led to extension of the south Peruvian Andes along a normal fault with evidence of Holocene slip. We use InSAR, seismology and field mapping to determine a source model for this event and show that extension at Parina is oriented NE-SW, which is parallel to the shortening direction in the adjacent sub-Andean lowlands. In addition, we use earthquake source models and GPS data to demonstrate that shortening within the sub-Andes is parallel to topographic gradients. Both observations imply that forces resulting from spatial variations in gravitational potential energy are important in controlling the geometry of the deformation in the Andes. We calculate 9 the horizontal forces per unit length acting between the Andes and South America due to these potential energy contrasts to be 4 − 8 × 10 12 N per metre along-strike of the mountain range. Normal faulting at Parina implies that the Andes in south Peru have reached the maximum elevation that can be supported by the forces transmitted across the adjacent foreland, which requires that the foreland faults have an effective coefficient of friction <0.2. Additionally, the onset of extension in parts of the central Andes following orogen-wide compression in the late Miocene suggests there has been a change in the force balance within the mountains. We propose that shortening on weak detachment faults within the Andean foreland since ∼5-9 Ma reduced the shear tractions acting along the base of the upper crust in the eastern Andes, leading to extension in the highest parts of the range

A Four Carbon Organonitrate as a Significant Product of Secondary Isoprene Chemistry

Abstract Oxidation of isoprene by nitrate radicals (NO3) or by hydroxyl radicals (OH) under high NOx conditions forms a substantial amount of organonitrates (ONs). ONs impact NOx concentrations and consequently ozone formation while also contributing to secondary organic aerosol. Here we show that the ONs with the chemical formula C4H7NO5 are a significant fraction of isoprene-derived ONs, based on chamber experiments and ambient measurements from different sites around the globe. From chamber experiments we found that C4H7NO5 isomers contribute 5%?17% of all measured ONs formed during nighttime and constitute more than 40% of the measured ONs after further daytime oxidation. In ambient measurements C4H7NO5 isomers usually dominate both nighttime and daytime, implying a long residence time compared to C5 ONs which are removed more rapidly. We propose potential nighttime sources and secondary formation pathways, and test them using a box model with an updated isoprene oxidation scheme

"Looking all lost towards a Cook's guide for beauty”: the art of literature and the lessons of the guidebook in modernist writing

This article explores the impact of the guidebook, especially the Baedeker series, on modernist literary culture. It argues that the guidebook is a literary phenomenon in its own right and that, as such, it attracts special attention from those engaged in defending and/or extending the category of literature as part of a modernist agenda. In particular, modernist writers are concerned as to whether the guidebook counts as a form of literature and, if so, what this means for the more familiar forms seen in their own essays, fiction and travelogues. What might the invention of the star system to rank scenes and monuments mean for the future of art criticism? How might the guidebook help or hinder the traveller in his/her pursuit of the beautiful or the picturesque? What does recourse to the guidebook reveal about the taste and education of the traveller? And, more pointedly still, what kind and quality of writing is the guidebook itself? This article surveys the extent of modernism's interest in the guidebook, both as a noteworthy new form and as a form modernist writers adapted for use in their own books, before turning in detail to commentary on the guidebook by E.M. Forster, Ernest Hemingway, H.D. and Virginia Woolf. In conclusion, it finds that the guidebook in modernism is very rarely just that. Instead, the guidebook finds unexpected affinities with modernism in its attempt to “modernise” literature – to make it more rational, more totalising and, in the eyes of its critics, less able to discriminate.This is an Accepted Manuscript of an article published by Taylor & Francis in Studies in Travel Writing on 4th March 2015, available online: http://wwww.tandfonline.com/10.1080/13645145.2014.994924

On the relational dynamics of caring: a psychotherapeutic approach to emotional and power dimensions of women’s care work

Care is double-edged and paradoxical, inspiring a vast range of strong feelings in both care-givers and care-recipients. This paper draws on ideas about psychotherapeutic relationships to offer a theorisation of the complex emotional and power dynamics and imaginative geographies of care. Examining the humanistic approach developed by Carl Rogers as well as the psychoanalytic tradition, I advance an interpretation of psychotherapeutic practices that foregrounds the fundamental importance of the emotional and power-inflected relationship between practitioners and those with whom they work. I show how different traditions offer conceptualisations of the shape of therapeutic relationships that are highly relevant to consideration of the emotional and power dynamics of giving and receiving care. Against this background I discuss current debates about care, emotions and power, drawing especially on feminist and disability perspectives and arguing that psychotherapeutic approaches offer a powerful lens through which to understand the emotional and power dynamics of caring relationships. I conclude by emphasising how this theorisation helps to illuminate ubiquitous features of women’s care work

The Synthesis of γ-l-glutamyl Peptides

The unequivocal synthesis of pteroyl-γ-l-glutamates has been achieved. The synthesis of -γ-glutamyl peptides, by "classical" methods, followed by coupling to a pteroic acid (2) derivative and by deprotection, was adopted as the general scheme. Attempts to repeat a previously published synthesis of γ-glutanyl peptides (Route 1) were abandoned when the dipeptide derivative (61) could not be crystallised. Crystalline and readily purified intermediates, including several which had not been previously prepared, were obtained during work on the novel synthesis (Route 2) of a pteroyl triglutamate derivative (99). Picolyl and 4-nitrobenzyl esters were used for carboxy-terminal protection and the peptide chain was built from an amino-terminal residue. Unfortunately, the pteroyl derivative (99) could not be deprotected and the route was abandoned; although it still provides a feasible synthesis of γ-glutamyl peptides. Chain elongation from an amino-terminal residue, allowing purification by salt formation at the γ-carboxy-terminal, was retained as a feature of subsequent schemes (Routes 3 and 4). The tertiary-butyl ester was employed for carboxy-terminal protection, to simplify final deprotection. Route 3 provided the fully-protected pteroyl tri-penta- and heptaglutamates (109), (110) and (111), which were fully characterised for the first time, although their synthesis by a different route had been previously reported. The use of protection by salt formation, at the γ-carboxy terminal, allowed the rapid synthesis (Route 4) of the pteroyl triglutamate derivative (114), which was readily deprotected to yield analytically pure pteroyl-γ-l-glutamyl-γ-l-glutamyl-L-glutamic acid. Very close attention was paid to the purity of the pteroic acid used in this work, so that, no doubt as a consequence, the pteroyl derivatives obtained were readily crystalline and easily purified. Previously, other workers have encountered severe purification difficulties when preparing similar compounds
