Methods for detecting and tracking natural hazards continue to increase in coverage, resolution and reliability. However, information on the social impacts of natural hazards is often lacking. Here we test the feasibility of using social media data (Twitter and Instagram) to detect and map an important class of natural hazard: wildfires. We analyse social media posts associated with wildfires over several time periods and compare them with wildfire occurrence data derived from satellite-based remote sensing data and on-the-ground observations. For the whole of the contiguous United States, we find significant temporal correlations between wildfire-related social media activity and wildfire occurrence, but also that there is substantial variation in the strength of this relationship at smaller spatial scales (states and counties). We then explore the utility of social media for location of wildfire events, finding good evidence to support further development of such methods. We conclude by discussing several challenges and opportunities for application of this novel data resource to provide information on impacts of natural hazards.

With an increasingly ageing population, vulnerable to effects of a warming climate, it is critical that planners better understand how to minimise heat stress in urban environments. This Interface article discusses the potential of green infrastructure to moderate temperatures and improve thermal comfort for ageing populations. We highlight the need to integrate planning for green infrastructure with accessible design to improve opportunities for seniors to remain physically and socially active. We illustrate how our current research in Queensland, Australia integrates green infrastructure and accessibility as key concepts in a decision-making tool for auditing aged care facilities.

Few studies have considered greenspace governance provision from a local government perspective. This paper applies previously overlooked insights from urban planning and social research, to invest...

Much research has examined the socio-spatial distribution of, and access to, urban greenspace; the challenges of supplying greenspace, especially in periods of dynamic urban change, remain poorly understood. Multiple factors shape urban greenspace provision, however understanding the role of leadership as a factor remains somewhat elusive. Addressing this critical knowledge gap, we employed a case study approach, using qualitative methods, to hear first-hand from the key stakeholders involved with municipal urban greenspace provision, to investigate how different types of leadership affected greenspace provision in Surrey, Canada – a dynamically changing mid-size city. Semi-structured interviews with 32 purposively selected participants reveal that here, both leadership and organizational culture influenced resources and decision-making supporting greenspace provision. Aligned political leadership and organizational leadership witnessed a significant increase in Surrey's urban greenspaces – the converse occurred in a later administration. Findings provide insights into the governance of greenspace; especially how different types of leadership can play a pivotal role in effective greenspace provision.

I have learned that we should never take the lives we lead for granted, and it is important for all of us to focus on the simple things that matter the most in everything we do. This is never more ...

Many peatland areas in Great Britain are managed as grouse moors, with regular burns as part of management practice to encourage heather growth. Remote sensing has the potential to monitor the size, location, and impact of these burns using new fine resolution satellites such as Sentinel-2. Google Earth Engine allows large areas to be analysed at small scale over several years, building up a visual record of fire occurrence. This study uses satellite data to map managed burns on several areas of moorland around Great Britain, and uses remote sensing methods to assess the impact of this management strategy on vegetation cover. The project also considers how areas subject to managed burns react to wildfire occurrence, with the 2018 Saddleworth wildfire as a case study.

Over the past two decades, there has been an efflorescence of park and greenspace research. This trend may reflect substantial increases in urban populations globally and concomitant pressures on land resources – including greenspace. But so far research has mainly tended to focus on demand rather than supply, and specifically the practice of provision – notwithstanding the body of literature studying disparities in greenspace access and geographic distribution through an environmental justice lens (e.g. using spatial analysis). Comparatively fewer studies have considered the interplay of factors that may shape local government’s capacity to supply greenspace. This paper reports results of a systematic quantitative review of the greenspace provision literature: assessing the factors that configure its supply, and different approaches to planning and assessing greenspace provision. A conceptual model is offered, explaining the interaction between greenspace provision factors across different scales. Findings suggest many cities continue to experience gaps between planned and actual greenspace provision. Moreover, urban greenspace is typically planned using a recreational standards approach, despite increasing demands for a range of ecosystem functions, services, and benefits. Future research should engage directly with greenspace managers responsible for urban greenspace delivery, especially in rapidly expanding cities, to illuminate points of convergence and divergence between theory and practice. Policy implications include consideration of holistic greenspace planning approaches that better recognise and respond to emerging demands upon, and for, urban greenspace.

Urban greenspaces provide diverse ecosystem functions, services and benefits to residents. Much commentary has been offered to date about citizens' demands for more urban greenspace. Less attention, however, has been given to the ‘supply side’ pressures experienced by local government in delivering urban greenspace, particularly in mid-sized cities. Greater attention to factors shaping supply is warranted, especially in the context of rapid population growth. By understanding how existing greenspace provision approaches can stymie the efforts of local government to meet citizens' needs, new approaches can be identified. This paper assesses several factors shaping urban greenspace provision in Surrey - a city within the Greater Vancouver area. Insights are derived from in-depth interviews with key stakeholders, public documents, and census and municipal data about parks and their context as a specific type of greenspace. Our findings suggest that governance tools, economy and property markets, and financial and natural resources manifest as core factors influencing urban greenspace provision in Surrey. A reliance on governance tools premised upon standards has created park provision paradoxes. Treating greenspace provision as a largely technocratic exercise may be limiting Surrey's ability to respond to changing politics, economics and population trends. We point to alternative approaches., Highlights • Providing urban greenspace is more than supplying land and revenue for facility development. • The clamour for more greenspace could be setting local governments up for some serious future policy deficiencies. • The tensions around land shortages, fiscal constraints and community expectations are driving the need for leadership.

Volatile esters are amongst the most important yeast-derived flavor-active compounds produced during brewery fermentation. Dissolved oxygen concentration has long been recognized as an effector for...

Comprehensive sets of chemical, microbiological and sensory methods have long been available to characterize individual beers and explore the relationships between raw materials, process conditions and the outcome of the brewing process. Although the majority of major brewers are increasingly using quality assurance as opposed to quality control as the basis of operation, the need to use chemical analyses is still perceived as an essential prerequisite to brewing. The requirement to meet the various legislative codes and the need to manage the consistency of international brands arising from several individual breweries make the possession of robust analytical procedures essential. In many breweries there is a trend towards devolving traditional analytical tasks from central quality control laboratories manned by dedicated technicians to satellite stations, where the analyses needed to support production are performed directly by process workers. Parallel to these changes is a desire to achieve a greater understanding of the complex relationships between beer analysis and overall quality, in particular, the identification of markers that allow for the identification of processes such as beer ageing. This review summarizes the ways in which brewing analytical methods and the suppliers of analytical apparatus are evolving to meet the needs of the current modern industry.

Repeated reuse or “serial repitching” of yeast between successive fermentations exposes brewing yeast cells to a number of biological, chemical, and physical stresses. It is generally accepted that...

A major concern for the brewing industry is achieving consistent fermentation cycle time without compromising the fermentation profile, the quality of the beer produced, or the yeast that is subseq...

The UK Hospital at Night (H@N) programme is hypothesised to improve efficiency of out-of-hours care. No studies have assessed a surgical programme or mechanisms of effect. This prospective study aimed to do so in a trauma and orthopaedic department over 10 weeks. Senior house officers recorded night shift activity. Mean time to attend referrals reduced from 29 to 15 minutes as a result of the programme (p=0.007). Workload and 30 day mortality and morbidity for hip fracture remained unchanged. The mechanisms underlying improvements are unclear, but may represent central organisation of workload.

The aim of this study was to determine the transcriptomic response of Saccharomyces pastorianus to environmental change during brewery propagation. Utilization of amino acids and fermentable carboh...

Amino acid utilization by yeast during brewer's wort fermentation influences both the fermentation performance and flavor profile of the finished product. To better understand the relationship betw...

Between May 2001 and May 2005, all 8834 adults admitted to our hospital with fractures to the limbs and pelvis were prospectively entered onto a database. Information was cross-referenced with the Office of National Statistics, and all patients who died during the study period were identified. Mortality rates were adjusted for age, gender and type of injury and cause of death was identified from hospital records. Neck of femur fractures accounted for 32% of admissions. Younger patients were more likely to be male and older patients more likely to be female. Overall 30-day and 1-year mortalities were 4.5 and 13%, respectively. Increased mortality was associated with age, male gender and fractures of the femur or pelvis.

The axially chiral dopants (R)-5,5'-, 5,6'-, and 6,6'-diheptyloxy-2,2'-spirobiindan-1,1'-dione ((R)-2, -3, and -4) were synthesized in optically pure form, and their absolute configurations were assigned by the exciton chirality method using circular dichroism spectroscopy. These new compounds were doped in four achiral liquid crystal hosts to give chiral smectic C* (SmC*) phases with spontaneous polarizations (Ps) that vary with the core structure of the host. The spontaneous polarization induced by the 5,5'-dialkoxy derivative (R)-2 is uniformly positive, whereas that induced by the 6,6'-dialkoxy derivative (R)-4 is uniformly negative and shows a different trend in host dependence. Polarization power (delta(p)) values range from +21 nC/cm2 for (R)-2 in 2',3'-difluoro-4-heptyl-4' '-nonyl-p-terphenyl (DFT) to -1037 nC/cm2 for (R)-4 in 4-(4'-heptyl[1,1'-biphen]-4-yl)-1-hexylcyclohexanecarbonitrile (NCB76). The unsymmetrical dopant (R)-3 behaves like a hybrid of the two symmetrical isomers, with lower absolute values of delta(p), on average, and varying signs of Ps. 2H NMR spectra of the doped mixtures using racemic mixtures of 2-4 with -OCD2C6H13 side-chains, in combination with phase diagrams, show that relatively minor changes in the dopant structure, that is, moving the alkoxy side-chains from the 5,5' to the 6,6' positions of the spirobiindandione core, have profound effects on dopant-host compatibility, and on the propensity of the dopant to exert chiral perturbations in the host environment. The variations in sign and magnitude of delta(p) as a function of alkoxy group positions are rationalized based on an analysis of zigzag conformations that conform to the binding site of the SmC host according to the Boulder model.

The synthesis and resolution of the chiral dopant (R)-2,2′-spirobiindan-5,5′-diheptyloxy-1,1′-dione is described. This new compound is doped in achiral SmC liquid crystal hosts to give a ferroelectric SmC* phase. The polarization power of the dopant varies with the core structure of the SmC host, from

This is the first study to use the English Indices of Multiple Deprivation 2007, the Government’s official measure of multiple deprivation, to analyse the effect of socioeconomic status on the incidence of fractures of the hip and their outcome and mortality. Our sample consisted of all patients admitted to hospital with a fracture of the hip (n = 7511) in Nottingham between 1999 and 2009. The incidence was 1.3 times higher (p = 0.038) in the most deprived populations than in the least deprived; the most deprived suffered a fracture, on average, 1.1 years earlier (82.0 years versus 83.1 years, p < 0.001). The mortality rate proved to be significantly higher in the most deprived population (log-rank test, p = 0.033), who also had a higher number of comorbidities (p = 0.001). This study has shown an increase in the incidence of fracture of the hip in the most deprived population, but no association between socioeconomic status and mortality at 30 days. Preventative programmes aimed at reducing the risk of hip fracture should be targeted towards the more deprived if they are to make a substantial impact.

Scale-up/scale-down techniques are vital for successful and safe commercial-scale bioprocess design and operation. An example is given in this review of recent studies related to beer production. Work at the bench scale shows that brewing yeast is not compromised by mechanical agitation up to 4.5 W/kg; and that compared with fermentations mixed by CO(2) evolution, agitation ≥ 0.04 W/kg is able to reduce fermentation time by about 20%. Work at the commercial scale in cylindroconical fermenters shows that, without mechanical agitation, most of the yeast sediments into the cone for about 50% of the fermentation time, leading to poor temperature control. Stirrer mixing overcomes these problems and leads to a similar reduction in batch time as the bench-scale tests and greatly reduces its variability, but is difficult to install in extant fermenters. The mixing characteristics of a new jet mixer, a rotary jet mixer, which overcomes these difficulties, are reported, based on pilot-scale studies. This change enables the advantages of stirring to be achieved at the commercial scale without the problems. In addition, more of the fermentable sugars are converted into ethanol. This review shows the effectiveness of scale-up/scale-down studies for improving commercial operations. Suggestions for further studies are made: one concerning the impact of homogenization on the removal of vicinal diketones and the other on the location of bubble formation at the commercial scale.

We performed a retrospective study of a departmental database to assess the efficacy of a new model of orthopaedic care on the outcome of patients with a fracture of the proximal femur. All 1578 patients admitted to a university teaching hospital with a fracture of the proximal femur between December 2007 and December 2009 were included. The allocation of Foundation doctors years 1 and 2 was restructured from individual teams covering several wards to pairs covering individual wards. No alterations were made in the numbers of doctors, their hours, out-of-hours cover, or any other aspect of standard patient care. Outcome measures comprised 30-day mortality and cause, complications and length of stay. Mortality was reduced from 11.7% to 7.6% (p = 0.007, Cox’s regression analysis); adjusted odds ratio was 1.559 (95% confidence interval 1.128 to 2.156). Reductions were seen in Clostridium difficile colitis (p = 0.017), deep wound infection (p = 0.043) and gastrointestinal haemorrhage (p = 0.033). There were no differences in any patient risk factors (except the prevalence of chronic obstructive pulmonary disease), cause of death and length of stay before and after intervention. The underlying mechanisms are unclear, but may include improved efficiency and medical contact time. These findings may have implications for all specialties caring for patients on several wards, and we believe they justify a prospective trial to further assess this effect.

A total of 146 patients were identified from a prospective database of all hip fractures over a 10-year period at a United Kingdom teaching hospital. The financial costs were calculated and analysed and then compared with the money recovered through the tariff produced by Payment by Results.A total of 62% of the study group were female; mean age of 79 years; mean length of stay of 39 days.Fractures occurred around total hip replacement (THR) in 63 cases, revision THR in 27 cases and hemiarthroplasty in 56 cases. Fixation of the fracture was performed in 61 cases, revision arthroplasty in 62 cases and 23 were treated non-operatively.The mean cost of treatment was £23,469 per patient (range £615–£223,000; median £18,031). Ward costs were responsible for 80.3%, theatre costs 5.7%, implants 6.7% and investigations 7.3%. The difference in cost was statistically significant when further surgery was required (p = 0.01) and length of stay was greater than 30 days (p < 0.0001), and when compared with the money recovered by the Trust(mean £3702; p < 0.0001). These results reveal the significant economic impact of treating this group of patients at specialist centres.

The fermentable carbohydrate composition of wort and the manner in which it is utilized by yeast during brewery fermentation have a direct influence on fermentation efficiency and quality of the final product. In this study the response of a brewing yeast strain to changes in wort fermentable carbohydrate concentration and composition during full-scale (3275 hl) brewery fermentation was investigated by measuring transcriptome changes with the aid of oligonucleotide-based DNA arrays. Up to 74% of the detectable genes showed a significant (p
