This article provides a new understanding of how organisations from the profit and non-profit sectors collaborated to fundraise for the arts in Interwar Britain. The central focus is the Contemporary Art Society (CAS) an organisation established in the belief that the art being acquired for national collections was inadequate. Based on an analysis of CAS committee members; the relationship between the CAS and commercial galleries through the Society’s subscriber scheme; and a number of collaborative exhibitions organised between 1919 and 1939, we argue that the CAS exercised cultural entrepreneurship, raising revenue to shape a new direction for the British Artworld.

– In this article we describe the trials and tribulations in the early stages to introduce cashless retail payments in the USA. We compare efforts by financial service firms and retailers. We then document the ephemeral life of one of these innovations, colloquially known as “Hinky Dinky”. We conclude with a brief reflection on the lessons these historical developments offer to the future of digital payments.

The UK automotive industry is home to a large number of foreign firms, demonstrating the open nature of competition. However, the industry necessitates both exploitative and explorative capabilities. Contingency theory suggests that firms align their internal structure with contextual factors. As such, the aims of this study were to investigate whether it was possible to distinguish home-owned (UK) and foreign-owned firms based upon: a) the microfoundations of ambidextrous production, which are conceptualised as lean and agile routines; and b) the tier at which these firms operate in the automotive supply chain. Survey data were collected from 85 home-owned and 55 foreign-owned firms within the UK Midlands automotive industry. Logistic regression results revealed that home-owned firms were significantly more likely to be implementing explorative (agile) production methods, whereas foreign-owned firms were significantly more likely to be implementing exploitative (lean) production. Home-owned and foreign-owned firms were found to be significantly more likely to be operating upstream and downstream in the automotive supply chain respectively. Thus, the findings support a contingency theory explanation, suggesting that firms align their performance priorities with contextual factors, but we argue that home-owned and foreign-owned firms have evolved to compete based on their different innovative capabilities, which are located at different tiers of the automotive supply chain. On this basis, although neither home-owned nor foreign-owned firms were found to be endogenously ambidextrous, we argue that foreign-owned firms internationalise into the UK automotive sector to exploit the explorative capabilities acquired by home-owned firms operating upstream in automotive supply chains, thus enabling ambidextrous capabilities at an exogenous, industrial level.

Treatment of severe pandemic influenza A(H1N1) 2009 virus infection with convalescent plasma suppressed the viral load and cytokine response, thereby reducing the subsequent risk of complication and death. Further studies by double-blind randomized controlled trial of plasma treatment in these patients are warranted., Background. Experience from treating patients with Spanish influenza and influenza A(H5N1) suggested that convalescent plasma therapy might be beneficial. However, its efficacy in patients with severe pandemic influenza A(H1N1) 2009 virus (H1N1 2009) infection remained unknown. Methods. During the period from 1 September 2009 through 30 June 2010, we conducted a prospective cohort study by recruiting patients aged ≥18 years with severe H1N1 2009 infection requiring intensive care. Patients were offered treatment with convalescent plasma with a neutralizing antibody titer of ≥1:160, harvested by apheresis from patients recovering from H1N1 2009 infection. Clinical outcome was compared with that of patients who declined plasma treatment as the untreated controls. Results. Ninety-three patients with severe H1N1 2009 infection requiring intensive care were recruited. Twenty patients (21.5%) received plasma treatment. The treatment and control groups were matched by age, sex, and disease severity scores. Mortality in the treatment group was significantly lower than in the nontreatment group (20.0% vs 54.8%; P = .01). Multivariate analysis showed that plasma treatment reduced mortality (odds ratio [OR], .20; 95% confidence interval [CI], .06-.69; P = .011), whereas complication of acute renal failure was independently associated with death (OR, 3.79; 95% CI, 1.15-12.4; P = .028). Subgroup analysis of 44 patients with serial respiratory tract viral load and cytokine level demonstrated that plasma treatment was associated with significantly lower day 3, 5, and 7 viral load, compared with the control group (P < .05). The corresponding temporal levels of interleukin 6, interleukin 10, and tumor necrosis factor α (P < .05) were also lower in the treatment group. Conclusions. Treatment of severe H1N1 2009 infection with convalescent plasma reduced respiratory tract viral load, serum cytokine response, and mortality.

Background. Infections caused by the pandemic H1N1 2009 influenza virus range from mild upper respiratory tract syndromes to fatal diseases. However, studies comparing virological and immunological profile of different clinical severity are lacking. Methods. We conducted a retrospective cohort study of 74 patients with pandemic H1N1 infection, including 23 patients who either developed acute respiratory distress syndrome (ARDS) or died (ARDS-death group), 14 patients with desaturation requiring oxygen supplementation and who survived without ARDS (survived-without-ARDS group), and 37 patients with mild disease without desaturation (mild-disease group). We compared their pattern of clinical disease, viral load, and immunological profile. Results. Patients with severe disease were older, more likely to be obese or having underlying diseases, and had lower respiratory tract symptoms, especially dyspnea at presentation. The ARDS-death group had a slower decline in nasopharyngeal viral loads, had higher plasma levels of proinflammatory cytokines and chemokines, and were more likely to have bacterial coinfections (30.4%), myocarditis (21.7%), or viremia (13.0%) than patients in the survived-without-ARDS or the mild-disease groups. Reactive hemophagocytosis, thrombotic phenomena, lymphoid atrophy, diffuse alveolar damage, and multiorgan dysfunction similar to fatal avian influenza A H5N1 infection were found at postmortem examinations. Conclusions. The slower control of viral load and immunodysregulation in severe cases mandate the search for more effective antiviral and immunomodulatory regimens to stop the excessive cytokine activation resulting in ARDS and death.

The pathogenic actinomycete Rhodococcus equi harbors different types of virulence plasmids associated with specific nonhuman hosts. We determined the complete DNA sequence of a vapB + plasmid, typically associated with pig isolates, and compared it with that of the horse-specific vapA + plasmid type. pVAPB1593, a circular 79,251-bp element, had the same housekeeping backbone as the vapA + plasmid but differed over an ≈22-kb region. This variable region encompassed the vap pathogenicity island (PAI), was clearly subject to selective pressures different from those affecting the backbone, and showed major genetic rearrangements involving the vap genes. The pVAPB1593 PAI harbored five different vap genes ( vapB and vapJ to - M , with vapK present in two copies), which encoded products differing by 24 to 84% in amino acid sequence from the six full-length vapA + plasmid-encoded Vap proteins, consistent with a role for the specific vap gene complement in R. equi host tropism. Sequence analyses, including interpolated variable-order motifs for detection of alien DNA and reconstruction of Vap family phylogenetic relationships, suggested that the vap PAI was acquired by an ancestor plasmid via lateral gene transfer, subsequently evolving by vap gene duplication and sequence diversification to give different (host-adapted) plasmids. The R. equi virulence plasmids belong to a new family of actinobacterial circular replicons characterized by an ancient conjugative backbone and a horizontally acquired niche-adaptive plasticity region.

Infection with Rhodococcus (Corynebacterium) equi is a well-recognised condition in foals that represents a consistent and serious risk worldwide. The condition manifests itself primarily as one of pulmonary abscessation and bronchitis, hence the terminology of 'rattles' derived from its most obvious clinical sign, frequently terminal when first identified. This review addresses the clinical manifestation, bacteriology and pathogenesis of the condition together with recent developments providing knowledge of the organism in terms of virulence, epidemiology, transmission and immune responses. Enhanced understanding of R. equi virulence mechanisms and biology derived from the recently available genome sequence may facilitate the rational development of a vaccine and the improvement of farm management practices used to control R. equi on stud farms in the future. Reliance on vaccines alone, in the absence of management strategies to control the on-farm challenge is likely to be disappointing.

Objectives: In this study a large random collection (n = 378) of Irish thermophilic Campylobacter isolates were investigated for the presence of integrons, genetic elements associated with the dissemination of anti- microbial resistance. Methods: Purified genomic DNA from each isolate was analysed by PCR for the presence of class 1 inte- grons. Four gene cassette-associated amplicons were completely characterized. Results: Sixty-two of the isolates possessed a complete class 1 integron with a recombined gene cassette located within a 1.0 kb amplicon containing an aadA2 gene. This cassette was present in both Campylo- bacter jejuni and Campylobacter coli isolates and following sequence analysis was shown to be similar to sequences recently reported in Salmonella enterica Hadar and on an 85 kb plasmid conferring quinolone resistance in Escherichia coli. Conclusions: Aminoglycoside aadA2-encoding class 1 integrons were identified among unrelated Campy- lobacter spp. Amino acid sequence comparisons revealed identical structures in both Salmonella and E. coli. The presence of class 1 integrons in Campylobacter spp. may be significant should these organisms enter the food chain and especially when antimicrobial treatment for severe infections is being considered.

To evaluate the effectiveness of a national approach to prescribing education on health professional students' prescribing and therapeutics knowledge, across multiple disciplines.In a university examination setting, 83 medical, 40 pharmacy and 13 nurse practitioner students from three different universities completed a set of multiple choice questions (MCQs) before and after completing an online module from the National Prescribing Curriculum (NPC). To minimize overestimation of knowledge, students had to indicate the level of certainty for each answer on a three-point scale. MCQs were scored using a validated certainty-based marking scheme resulting in a composite score (maximum 30 and minimum -60). Students were asked to rate their perception of usefulness of the module.At the pre-module phase, there were no significant differences in the composite MCQ scores between the medical (9.0 ± 10.3), pharmacy (10.2 ± 10.6) and nurse practitioner (8.0 ± 10.7) students. The scores improved significantly for all groups at the post-module phase (P 0.01 for all groups) by similar extents (post-module results: medical, 14.5 ± 9.6; pharmacy, 14.4 ± 9.9; nurse practitioner, 12.1 ± 9.6). 39.4% of the MCQs answered incorrectly with high level of certainty at the pre-module phase were still answered incorrectly with high level of certainty at the post-module phase. Almost all students (with no significant difference between the groups) found the NPC modules, post-module MCQs and feedback useful as a learning tool.A national online approach to prescribing education can improve therapeutics knowledge of students from multiple disciplines of health care and contribute towards streamlining interdisciplinary learning in medication management.

In a world addicted to oil and the prodigious infrastructure that produces it there are distinct spatial variations in oil dependence and vulnerability. Depending on a country’s location, it will have dependencies of different sources of oil. Disruptions in any one source of oil will have differing impacts in both the magnitude and breadth of countries affected. To begin to understand such a volatile landscape this paper will review pertinent literature surrounding oil shocks and propose a model of how they can be geospatially modeled. Specifically the modeling will calculate an Oil Import Vulnerable Import Index, an Oil Dependency Index, and the percentage reduction in import diversity for 63 countries.

The re-building of institutional capacity in post-disaster and post-war zones requires massive engineering efforts. The needs of people on the ground in these situations are often approached from the top-down via emergency groups, NGOs, and governments (Jones, Wilson, & Rathmell, 2005). For actors on the ground, research has shown that such efforts may require ad-hoc capacity to adapt, understand, share, and quickly assess their situational context (NRC, 2007). In the study outlined below, participants were plagued by a variety of barriers ranging from lack of power to lack of trained technical personnel. In a report on improving geospatial support for disaster management the National Research Council identified several critical barriers to successful response to emergencies: a combination of lack of adequately trained staff and technically complicated geospatial software tools, lack of agreement and means for successful data distribution, and data “format[s] which are unrecognizable or unusable [for] responding agencies (NRC, 2007: 157).” A collection of researchers, open source software projects and companies has been developing technology to advance the delivery of geospatial and data sharing capabilities to non-technical users in ad-hoc environments. Recently, a few of these participants coordinated a volunteer effort to test how individual actors might apply such technology in Afghanistan.

A small study was carried out in order to examine the molecular presence of bla CTX-M gene phylogenetic groups in E. coli (n=263) isolated from food (n=54), water (n=7), animal sources (n=69), using consensus bla CTX-M primers and PCR, in addition to human faecal isolates (n=69) and VTEC O157:H7 (n=64). None of the clinically significant faecal VTEC O157:H7 isolates were shown to carry blaCTX-M type phylogenetic groups, nor were such phylogenetic groups observed in any of the food, water and animal isolates. One community faecal isolate (1/69; 1.4%), dating from 1997, carried this phylogenetic group. As recent work has indicated that a significant proportion of such phylogenetic groups are carried in community isolates of E. coli with little or no hospital contact, it is important that surveillance is increased to identify potential source(s) and reservoirs of such resistance in the community. Further prospective surveillance is thus required to help elucidate the origins of such phylogenetic group in the community. The significance of this study is that the ESBL-producing E. coli associated with local hospital outbreaks is not commonly found in local food, water or animal sources. In addition, given that ESBL-producing E. coli is now a significant organism, both in hospitals and nursing homes in Northern Ireland, this report demonstrates that such organisms were present in the community, as early as 1997.

We report the genome of the facultative intracellular parasite Rhodococcus equi, the only animal pathogen within the biotechnologically important actinobacterial genus Rhodococcus. The 5.0-Mb R. equi 103S genome is significantly smaller than those of environmental rhodococci. This is due to genome expansion in nonpathogenic species, via a linear gain of paralogous genes and an accelerated genetic flux, rather than reductive evolution in R. equi. The 103S genome lacks the extensive catabolic and secondary metabolic complement of environmental rhodococci, and it displays unique adaptations for host colonization and competition in the short-chain fatty acid–rich intestine and manure of herbivores—two main R. equi reservoirs. Except for a few horizontally acquired (HGT) pathogenicity loci, including a cytoadhesive pilus determinant (rpl) and the virulence plasmid vap pathogenicity island (PAI) required for intramacrophage survival, most of the potential virulence-associated genes identified in R. equi are conserved in environmental rhodococci or have homologs in nonpathogenic Actinobacteria. This suggests a mechanism of virulence evolution based on the cooption of existing core actinobacterial traits, triggered by key host niche–adaptive HGT events. We tested this hypothesis by investigating R. equi virulence plasmid-chromosome crosstalk, by global transcription profiling and expression network analysis. Two chromosomal genes conserved in environmental rhodococci, encoding putative chorismate mutase and anthranilate synthase enzymes involved in aromatic amino acid biosynthesis, were strongly coregulated with vap PAI virulence genes and required for optimal proliferation in macrophages. The regulatory integration of chromosomal metabolic genes under the control of the HGT–acquired plasmid PAI is thus an important element in the cooptive virulence of R. equi., Author Summary Rhodococcus is a prototypic genus within the Actinobacteria, one of the largest microbial groups on Earth. Many of the ubiquitous rhodococcal species are biotechnologically useful due to their metabolic versatility and biodegradative properties. We have deciphered the genome of a facultatively parasitic Rhodococcus, the animal and human pathogen R. equi. Comparative genomic analyses of related species provide a unique opportunity to increase our understanding of niche-adaptive genome evolution and specialization. The environmental rhodococci have much larger genomes, richer in metabolic and degradative pathways, due to gene duplication and acquisition, not genome contraction in R. equi. This probably reflects that the host-associated R. equi habitat is more stable and favorable than the chemically diverse but nutrient-poor environmental niches of nonpathogenic rhodococci, necessitating metabolically more complex, expanded genomes. Our work also highlights that the recruitment or cooption of core microbial traits, following the horizontal acquistion of a few critical genes that provide access to the host niche, is an important mechanism in actinobacterial virulence evolution. Gene cooption is a key evolutionary mechanism allowing rapid adaptive change and novel trait acquisition. Recognizing the contribution of cooption to virulence provides a rational framework for understanding and interpreting the emergence and evolution of microbial pathogenicity.

Background: The largest contributor to delayed receipt of reperfusion therapy for acute coronary syndrome (ACS) is patient delay in recognizing symptoms and seeking treatment. Objectives: We tested the effect of an education and counseling intervention designed to reduce patient delay on knowledge, attitudes and beliefs about ACS symptoms and the response to symptoms. Methods: We conducted a 2-group randomized controlled trial in 3,522 people with coronary heart disease (CHD). The intervention group (n=1777) received a one-on-one education and counseling session from a cardiovascular nurse that addressed informational, emotional, and social responses associated with onset of ACS symptoms, followed by a telephone call at one month. The control group (n=1745) received usual care. Knowledge, attitudes and beliefs were measured at baseline and 3 and 12 months using the ACS Response Index. Repeated measures ANOVA was used to assess differences in outcomes over time. Results: Patients were 67±11 years old; 67% were male and 45% had history of AMI. Knowledge, attitudes and beliefs scores increased significantly from baseline in the intervention group compared to the control group at 3 months and remained higher at 12 months (Table ). C onclusion: A relatively short one-on-one education and counseling intervention significantly increased knowledge, attitudes and beliefs about ACS and response to ACS symptoms, sustained to 12 months following the intervention. The results of the study suggest that individualized education for those at high risk of ACS is effective in increasing the knowledge, attitudes and beliefs required to make an appropriate decision about seeking care for ACS.

Reasons for performing study: Rhodococcoccus equi is a significant cause of bronchopneumonia in foals worldwide. Infection of the lungs is believed to result from inhalation of virulent R. equi in dust from contaminated environments. A measure of infectious risk in an environment is the level of airborne contamination. Objectives: To assess and compare the level of airborne virulent R. equi in paddocks and stables. Methods: Air samples were collected sequentially over the 2003 foaling season from the paddocks and stables on 3 Irish horse breeding farms affected by R. equi pneumonia. Colony blotting and DNA hybridisation techniques allowed quantitation of virulent R. equi. Results: The odds of detecting airborne virulent R. equi in stables were 17.3 times greater than in paddocks. The median airborne concentration of virulent R. equi was significantly higher (P

Telomere length has been linked to disease stage and degree of (pan-)cytopenia in patients with bone marrow failure syndromes. The aim of the current study was to analyze the impact of replicative stress on telomere length in residual glycosylphosphatidylinositol-positive (GPI+) versus GPI– hematopoiesis in patients with paroxysmal nocturnal hemoglobinuria (PNH). Peripheral blood granulocytes from 16 patients and 22 healthy individuals were analyzed. For this purpose, we developed proaerolysin flow-FISH, a novel methodology that combines proaerolysin staining (for GPI expression) with flow-FISH (for telomere length measurement). We found significantly shortened telomeres in GPI– granulocytes (mean ± SE: 6.26 ± 0.27 telomere fluorescence units [TFU]), both compared with their GPI+ counterparts (6.88 ± 0.38 TFU; P = .03) as well as with age-matched healthy individuals (7.73 ± 0.23 TFU; P < .001). Our findings are in support of a selective growth advantage model of PNH assuming that damage to the GPI+ hematopoietic stem-cell (HSC) compartment leads to compensatory hyperproliferation of residual GPI–HSCs.

Objective—To compare isolates of Rhodococcus equi on the basis of geographic source and virulence status by use of pulsed-field gel electrophoresis (PFGE). Sample Population—290 isolates of R equi(218 virulent isolates from foals and 72 avirulent isolates from feces, soil, and respiratory tract samples) obtained between 1985 and 2000 from horses and horse farms from 4 countries. Procedure—DNA from isolates was digested with the restriction enzyme AseI and tested by use of PFGE. Products were analyzed for similarities in banding patterns by use of dendrograms. A similarity matrix was constructed for isolates, and the matrix was tested for nonrandom distributions of similarity values with respect to groupings of interest. Results—There was little grouping of isolates on the basis of country, virulence status, or region within Texas. Isolates of R equi were generally < 80% similar, as determined by use of PFGE. Isolates from the same farm generally were rarely of the same strain. Conclusions and Clinical Relevance—Considerable chromosomal variability exists among isolates of R equi obtained from the same farm, sites within Texas, or among countries from various continents. Only rarely will it be possible to link infections to a given site or region on the basis of analysis of isolates by use of PFGE of chromosomal DNA. (Am J Vet Res 2003;64:153–161)

The decision to withdraw or withhold life supporting treatment in moribund patients is difficult under any circumstances. When the patient becomes incompetent to clarify their wishes regarding continued maintenance in long-term facilities, surrogates sometimes cannot agree, further clouding the issue. We examine a case where the State's interests come into play, forcing a controversial resolution.

Toxic blooms of cyanobacteria, including Anabaena species, which are neurotoxic, and Microcystis , which is hepatotoxic, are becoming increasingly common in potable water sources. Normal flocculation and chlorination processes do not remove the toxicity. The laboratory and pilot-plant experiments described in this article showed that the toxicity can be removed by both powdered and granular activated carbon, with and without chlorination, alum flocculation, and polyelectrolyte addition.

M. aeruginosa is a bloom-forming cyanobacterium which is common in fresh-water lakes. It contains a potent hepatotoxin which when purifed has been shown to be a heptapeptide of molecular weight 1019. The toxin was iodinated with 1251 using the lactoperoxidase method, the labelled toxin administered iI).travenously to adult female rats and the half-life and organ distribution measured. The blood half-life after redistribution into extracellular pools was 42 min. The liver and kidneys showed accumulation of 21�7 � 1�1 and 5�6 � 0�2% of the dose respectively after 30 min. Little accumulation was observed in other organs and tissues. Small-intestinal contents and urine contained 9�4 � 6� 1 and 2�9 � 1'2% of the dose respectively after 120 min. It was concluded that the liver is the main target organ for both accumulation and excretion of the toxin.
