We revisit the graphic table of QCD signatures in our 1996 Annual Reviews article “The Search for the Quark–Gluon Plasma” and assess the progress that has been made since its publication towards providing quantitative evidence for the formation of a quark–gluon plasma in relativistic heavy-ion collisions and its characteristic properties.

AbstractProblem, research strategy, and findingsTakeaway for practicePlanning departments use nonprofit subcontractors to increase neighborhood community organizing. However, this is the first study to assess practitioner perceptions of this subcontracting arrangement and its effect on addressing or perpetuating racial inequities in neighborhood community organizing. We used 39 interviews in an exploratory study of Oklahoma City (OK) and a nonprofit that is contracted to do neighborhood organizing. Interviewees described how the organization improved some community organizing given its detailed approach to formalize neighborhood associations. At the same time, participants believed that the subcontracting relationship and focus on formalized neighborhood associations perpetuated existing disparities in community organizing given long-standing challenges of systemic racism. The study is limited in its focus on one example but provides implications for local municipalities that contract out community development services.Nonprofits can be important partners in expanding community organizing in neighborhoods. We offer recommendations for how planners can assess and work with subcontractor community organizing nonprofits in various stages of contracts, such as co-creating metrics for success and evaluating these outcomes with the subcontractor. Planning departments can then better understand how to modify future contracts to address racial equity disparities. Planners also should understand how these organizations may highlight ongoing ineffectiveness and challenges of working with diversifying publics and existing disparities in the planning process.

Scholars acknowledge that postconflict urbanism is undertheorized and underdeveloped for practical governance or sustainable urban management, especially in sub-Saharan Africa, which has unfortunately experienced significant conflict in the post-independence period. We argue that postconflict redevelopment theory and practice under appreciates liminal spaces and the precarious existence of postconflict people, especially postconflict women. We examine the extant literature on Gulu, Uganda, to develop theory and urban management concepts around the notion of the gendered postconflict city as a unique urban identity and re-center the analysis on the everyday experiences, agency, and city building practices of women. We posit three realities for understanding the gendered postconflict city: (1) the postconflict gendered city is a liminal space beyond the notions of contingency and fluidity often assigned to African cities, (2) it is a place of deep and abiding trauma, and (3) it is a place of invisibility and precarity for women who self-organize to reduce precarity. We make a series of recommendations for postconflict urban management based on these realities that include recognizing liminality in postconflict planning and setting aside the impulse to prioritize the global competitiveness of postconflict cities above all else. These have important implications for NGO and national development practices. [ABSTRACT FROM AUTHOR]

This paper looks at the geographical composition of European Ryder Cup teams in the biennial golf match against the United States of America. It looks at the different nationalities that have been a part of Team Europe and considers what combination of players is most likely to contribute to European success. It was found that Europe is most successful when more countries are represented. A European team will be more likely to win a match staged in Europe and that the best chance of doing this is when the team comprises of 8 or 9 different nationalities. [ABSTRACT FROM AUTHOR]

In 2008 Joe Calzaghe (from Wales) fought Bernard Hopkins (from the USA) in a light-heavyweight boxing match. Prior to the fight Hopkins had taunted Calzaghe with the refrain that he would never lose to a white boy. This paper assesses the interplay of discourses surrounding race and nation in the build-up to the contest between the two boxers. The analysis highlights how simplistic binaries are used to perpetuate notions of difference and considers how this accentuates divides in contested racial and national terrains.

Context: The prevalence of obesity has grown in the US over the decades. The temporal trends of body mass index categories in the last two years of life are poorly understood.Objectives: To describe the trends in body mass categories in the last two years of life over the past two decades controlling for other demographic changes.Methods: We performed a cross-sectional study of prospectively collected survey data from the nationally representative Health and Retirement Study (HRS) among decedents who died between 1998 and 2018. We categorized BMI into five categories and calculated the proportion of decedents with each BMI category during each four epochs (1998-2003, 2004-2008, 2009-2013, 2014-2018). We examined trends in regression models with survey wave groupings modeled as an orthogonal polynomial and adjusted for factors commonly associated with BMI: sex, age, race, ethnicity, education, and tobacco use.Results: The analytic cohort included 14,797 decedents. From 1998-2003 to 2014-2018 time periods, those categorized as having mild-to-moderate obesity in the last two years of life increased from 12.4% to 14.8% (linear trend P < 0.001), a 19% increase. Severe obesity increased from 1.9% to 4.3%, a 126% increase (linear trend P < 0.001). Underweight decreased from 9.9% to 5.9%, a 40% decrease (linear trend P < 0.001), adjusted for demographic factors. Adjusted quadratic temporal trends for BMI category were nonsignificant, except for in mild-to-moderate obesity.Conclusion: Severe obesity has increased greatly while underweight has decreased. As obesity increases in the final years of life, it is critical to assess how the existing and future palliative services and end of life care system address body size and weight.

Math and the Mouse is an intensive, collaborative, project-driven, study away course that runs during the three-week May Experience term at Furman University and has many of the at- tributes of a course-based undergraduate research experience in mathematics. We take twelve students to Orlando, Florida to study the behind-the-scenes mathematics employed to makeWalt DisneyWorld oper- ate efficiently. Students learn techniques of mathematical modeling (mostly resource allocation, logistics, and scheduling models), statistical analysis (mostly probability, clustering, data collection, and hypoth- esis testing), and ow management (queuing theory and some beginning ow dynamics) in an applied setting. Through planned course modules, collaborative activities, conversations with guest speakers, and three group projects, one of which is of the students' choosing, this academic experience provides an engaged learning experience that shows how material from eleven academic courses comes together in connection with real-world applications.

Background: Children are important transmitters of norovirus infection and there is evidence that laboratory reports in children increase earlier in the norovirus season than in adults. This raises the question as to whether cases and outbreaks in children could provide an early warning of seasonal norovirus before cases start increasing in older, more vulnerable age groups.Methods: This study uses weekly national surveillance data on reported outbreaks within schools, care homes and hospitals, general practice (GP) consultations for infectious intestinal disease (IID), telehealth calls for diarrhoea and/or vomiting and laboratory norovirus reports from across England, UK for nine norovirus seasons (2010/11-2018/19). Lagged correlation analysis was undertaken to identify lead or lag times between cases in children and those in adults for each surveillance dataset. A partial correlation analysis explored whether school outbreaks provided a lead time ahead of other surveillance indicators, controlling for breaks in the data due to school holidays. A breakpoint analysis was used to identify which surveillance indicator and age group provided the earliest warning of the norovirus season each year.Results: School outbreaks occurred 3-weeks before care home and hospital outbreaks, norovirus laboratory reports and NHS 111 calls for diarrhoea, and provided a 2-week lead time ahead of NHS 111 calls for vomiting. Children provided a lead time ahead of adults for norovirus laboratory reports (+ 1-2 weeks), NHS 111 calls for vomiting (+ 1 week) and NHS 111 calls for diarrhoea (+ 1 week) but occurred concurrently with adults for GP consultations. Breakpoint analysis revealed an earlier seasonal increase in cases among children compared to adults for laboratory, GP and NHS 111 data, with school outbreaks increasing earlier than other surveillance indicators in five out of nine surveillance years.Conclusion: These findings suggest that monitoring cases and outbreaks of norovirus in children could provide an early warning of seasonal norovirus infection. However, both school outbreak data and syndromic surveillance data are not norovirus specific and will also capture other causes of IID. The use of school outbreak data as an early warning indicator may be improved by enhancing sampling in community outbreaks to confirm the causative organism. [ABSTRACT FROM AUTHOR]

Symptom profiles have previously been identified for infectious intestinal disease (IID) which distinguish bacterial from viral organisms. However, there is evidence that the seasonality, severity, and duration of IID may differ between children, adults and elderly. A secondary data analysis was undertaken to explore whether symptom profiles for bacterial and viral IID vary across different age groups. Data from 844 cases of IID were divided into three age categories: <16 years, 16–65 years and >65 years. Multivariable logistic regression modelling was used to compare the significance of different symptoms across the three age groups. The odds of bacterial IID in children were increased by onset in the summer, diarrhoea in the absence of vomiting and fever. These symptoms were also associated with lower odds of a viral pathogen. In adults, diarrhoea but no vomiting, bloody diarrhoea and diarrhoea lasting more than 3 days were associated with increased odds of a bacterial organism, whilst onset in the winter or spring and a loss of appetite were associated with viral IID. In the elderly, diarrhoea in the absence of vomiting and diarrhoea lasting more than 3 days were associated with higher odds of bacterial IID and lower odds of a viral cause. Only diarrhoea in the absence of vomiting emerged as a key symptom across all three age groups. Variation in symptom profiles by age has implications for clinicians, public health specialists and epidemiologists who use symptoms to guide presumptive diagnoses in the absence of microbiological confirmation.

Infertility is a significant public health concern in the United States. As such, utilization of infertility services, including pharmacotherapeutic treatments, is prevalent, and the role of the pharmacist as part of the health care team is essential. Pharmacists can assist patients by providing education on infertility causes, risk factor mitigation, referrals, nonpharmacologic and pharmacologic management options, navigation of the prescription process, and resource availability for the significant financial burden accompanying infertility treatment. In-depth pharmacotherapeutic information may not be readily available to pharmacists dispensing and counseling on these medications, and infertility management regimens are often varied and complicated requiring more in-depth counseling on use and administration. Given the complexity of infertility management, pharmacists are a valuable patient support and education resource. This article provides an in-depth review of infertility management strategies, both nonpharmacologic and pharmacologic. [ABSTRACT FROM AUTHOR]

Purpose: CTA is routinely ordered on level II blunt thoraco-abdominally injured patients for assessment of injury to the thoracic aorta. The vast majority of such assessments are negative. The question being asked is, Does the accurate interpretation of the three mediastinal signs permit reliable determination of which patients need CTA for aortic assessment? The purpose of this investigation was to evaluate the role of three specifically selected mediastinal anatomic signs on the initial supine chest radiograph (CXR) of adult level II blunt thoraco-abdominally injured patients for the presence or absence of a mediastinal hematoma. The presence of a mediastinal hematoma is typically used as an indicator for computed tomographic angiography (CTA). The three mediastinal signs are the right para-tracheal stripe (RPTS), left para-spinal line (LPSL), and the left apical extra-pleural area (LAPA).Materials and Methods: The patient triage designation (level II trauma) was made by the attending physician at the time of admission. The initial CXR image and the CTA report of the 197 adult blunt level II thoraco-abdominally injured patients obtained on the day of admission were compared. The CXR of each of the 197 patients was independently assessed by each of four observers specifically for the status of the three mediastinal signs. Each observer was blinded to the CTA report until after the status of the three mediastinal sign evaluation had been determined. Two or three of the mediastinal signs being positive were required to determine that the CXR was positive for a mediastinal hematoma.Results: Two or three of the selected mediastinal signs were normal in 192 (97.5%) patients. None of these patients had either a mediastinal hematoma or a major aortic injury on CTA. In each of the remaining five (2.5%) patients, two or three of the mediastinal signs were abnormal. Each of these patients had a mediastinal hematoma and a major thoracic aortic injury on CTA.Conclusions: This preliminary study suggests that the accurate interpretation of the three specifically selected mediastinal signs on the initial supine CXR of adult level II blunt thoraco-abdominally injured patients could reduce the need for routine CTA for thoracic aortic injury assessment, and requires verification by an additional study.

The influence of a polymer capping layer on the deformation of purified single-wall carbon nanotube (SWCNT) networks is analyzed through the wrinkling of compressed SWCNT-polymer bilayers on polydimethylsiloxane. The films exhibit both wrinkling and folding under compression and we extract the elastoplastic response using conventional two-plate buckling schemes. The formation of a diffuse interpenetrating nanotube-polymer interface has a dramatic effect on the nanotube layer modulus for both metallic and semiconducting species. In contrast to the usual percolation exhibited by the pure SWCNT films, the capped films show a crossover from "composite" behavior (the modulus of the SWCNT film is enhanced by the polymer) to "plasticized" behavior (the modulus of the SWCNT film is reduced by the polymer) as the SWCNT film thickness increases. For almost all thicknesses, however, the polymer enhances the yield strain of the nanotube network. Conductivity measurements on identical films suggest that the polymer has a modest effect on charge transport, which we interpret as a strain-induced polymer penetration of interfacial nanotube contacts. We use scaling, Flory-Huggins theory, and independently determined nanotubenanotube and nanotube-polymer Hamaker constants to model the response. [ABSTRACT FROM AUTHOR]

RF-modulated electron beams, such as those produced by an RF linear accelerator, propagating through vacuum, air, and solid matter are well known to drive signals in microwave cavities and waveguides via interactions with these structures. Past experiments with a microwave waveguide in a radiation-shielded vault indicated the presence of a multipath propagation phenomenon, hypothesized to be a result of reflections of RF-modulated x rays. In this work, we study the signals induced in a microwave coaxial cable from nearby beam interactions with materials commonly found in accelerator facilities in order to better understand RF production and propagation in these environments. Our results show that (1) when an RF-modulated electron beam is incident on a block of aluminum, lead, or concrete, the frequency content of the induced microwave signals is strongly dependent on the orientation of the block and the relative position of the detector, (2) at least some of the detected signals are consistent with reflections off of the blocks, and (3) beam interactions with the blocks can induce appreciable microwave signals in detectors located tens of cm from the block.

Major geological processes have shaped biogeographical patterns of riverine biota. The Edwards Plateau of central Texas, USA, exhibits unique aquatic communities and endemism, including several species of freshwater mussels. Lampsilis bracteata (Gould, 1855) is endemic to the Edwards Plateau region; however, its phylogenetic relationship with other species in the Gulf coastal rivers and Mississippi River basin is unknown. We evaluated phylogenetic relationships, shell morphologies and soft anatomy characters of L. bracteata and a closely related congener, Lampsilis hydiana (Lea, 1838) throughout their ranges. Our results showed the presence of an undescribed species: Lampsilis bergmanni sp.n. Lampsilis bracteata and L. bergmanni sp.n. share similar shell morphologies and soft anatomy characters; however, they are genetically distinct. Geological processes, such as faulting and sea‐level changes during the Miocene to Pliocene, are likely to have facilitated diversification of Lampsilis species, resulting in isolation of L. bracteata on the Edwards Plateau and diversification between L. bergmanni sp.n. and L. hydiana. We conclude that L. bracteata range is restricted to the Colorado River basin, whereas L. bergmanni sp.n. occurs only in upstream reaches of the Guadalupe River basin. Conservation actions are warranted for both species due to their restricted distributions and potential anthropogenic threats. [ABSTRACT FROM AUTHOR]

Introduction: End‐stage renal disease (ESRD) has been associated with a range of cognitive deficits, including impaired retrospective memory and attention. Prospective memory (PM) is memory for future intentions, such as remembering to take medication on time. Prospective memory has not been examined in any ESRD patients; yet, the implications upon diet and medication management could potentially have detrimental effects on patient welfare. This is the first study to examine PM in ESRD patients being treated with hemodialysis (HD). Methods: Hemodialysis patients (n = 18) were compared with age‐matched and education‐matched controls (n = 18) on a boardgame task that emulates a typical week of activities (i.e., grocery shopping, meetings with friends), requiring the participant to remember a series of upcoming tasks. Other measures were also examined, including general cognitive decline, measures of independent living, IQ, and mood. Findings: Patients recalled significantly fewer upcoming events than the control group, suggesting an impairment of PM. No significant relationship was found between PM performance and any other measures, suggesting the difference between groups is likely due to the effects of ESRD, HD treatment, or some associated comorbidity. Discussion: This is the first study to demonstrate a PM deficit in patients undergoing HD treatment. This finding contributes to the current knowledge of the cognitive profile of patients undergoing HD while also highlighting the implications that a PM deficit may have on patient quality of life. The finding may go some way to explaining variances in patients' ability to monitor and adhere to medication and dietary regimes and, ultimately, to live independently. The study also highlights the necessity of viewing treatment for ESRD as a holistic process to maximize patient well‐being. [ABSTRACT FROM AUTHOR]

This paper contributes to lines of scholarship that both seek to interrogate the notion of hope within African urbanization as well as the integration of the needs of urban youth. It investigates drawn cognitive maps of informal settlements and accompanying essays authored by 123 vulnerable youth living in Lusaka's informal settlements to better understand how the participants locate hope in their surroundings. The analysis suggests that there are several social-spatial anchors of hope in the city's informal settlements that simultaneously orient their day-to-day lives and long-term aspirations. These locations and their associated aspirations are mitigated both by the larger social and physical contexts. These findings suggest that the youth locate hope and despair throughout their settlements in discrete locations and also see hope as a group effort. The findings are also used to make recommendations for how urban managers can use this information to support the hopes of informal settlement youth. [ABSTRACT FROM AUTHOR]

Passing an electron beam through an aperture can serve to reduce the beam current or change the transverse beam profile. For a sufficiently intense beam, space charge will drive a radial expansion of the beam, which may cause the current passing through the aperture to decrease even though the current arriving at the aperture is increasing. When a gridded electron gun is used, this may be expressed by stating that the transconductance of the apertured gun is negative. Here, we explain this effect and explore some of the key factors governing when it can occur and influencing its strength. [ABSTRACT FROM AUTHOR]

This paper examines media representations of Welsh rugby player Gavin Henson, arguing that through analysis of media discourses we can trace shifting shapes of masculinities in the (post)modern era of sport. Contradiction and inconsistencies are prevalent in the narratives that accompany the equally conflicting images of Henson, who both conforms to and challenges traditional rugby playing masculinities. The paper examines articles from Welsh and British newspapers from a critical (pro)feminist perspective, arguing that Henson transcends boundaries in a way that no rugby player has ever done before and analyzes his place as the first metrosexual rugby star. The study also examines the somewhat problematic concept of metrosexuality within critical (pro)feminist theories of sport and attempts to conceptualize the position and significance of the term. This work brings images of the continual, dialectic process of the (re)defining of gender identities to the study of masculinities, and sport masculinities in particular. [ABSTRACT FROM AUTHOR]

Vitiligo is a chronic inflammatory autoimmune disease that targets melanocytes, causing skin de-pigmentation. A cream formulation of the Janus kinase (JAK) 1/JAK2 inhibitor, ruxolitinib demonstrated substantial re-pigmentation in a phase 2 study in adults with vitiligo. In two multinational, randomized, double-blind, vehicle-controlled phase 3 studies of adults and adolescents with vitiligo (TRuE-V1, NCT04052425; TRuE-V2, NCT04057573), ruxolitinib cream was superior to vehicle at Week 24 in the primary and all key secondary endpoints. Pooled results on achievement of ≥50% improvement in the Vitiligo Area Scoring Index (VASI50) by body region in TRuE-V1/TRuE-V2 were analysed and are reported herein. Patients ≥12years old with nonsegmental vitiligo (NSV) with de-pigmentation covering ≤10% total body surface area, including a total VASI (T-VASI) score ≥3, were eligible for enrolment. Patients were randomized 2:1 to twice-daily 1·5% ruxolitinib cream or vehicle for 24weeks, after which all patients could apply twice-daily 1·5% ruxolitinib cream through Week 52 (open-label extension). The percentage of patients achieving VASI50 was calculated for each body region [head and neck (not including face), hands, upper extremities, trunk (including genitals), lower extremities, feet] and total body (excluding face). In total, 674 patients were randomized in the TRuE-V studies (ruxolitinib cream, n=450; vehicle, n=224); 661 patients were included in the efficacy analysis (1 site excluded for data quality) and 569 continued in the open-label extension (ruxolitinib cream from Day 1, n=385; crossover from vehicle, n=184). At Week 12, more patients who applied 1·5% ruxolitinib cream vs. vehicle achieved VASI50 in the head and neck (28·3% vs. 19·8%), upper extremities (14·1% vs. 11·0%), trunk (15·5% vs. 12·9%) and lower extremities(15·1% vs. 10·9%). At Week 24, more patients who applied 1·5% ruxolitinib cream vs. vehicle achieved VASI50 regardless of body region [head and neck, 45·3% vs. 23·8%; hands, 24·9% vs. 14·4%; upper extremities, 33·2% vs. 8·2%; trunk, 26·4% vs. 12·3%; lower extremities, 29·5% vs. 12·2%; feet, 18·5% vs. 12·5%; total body (excluding face), 20·8% vs. 6·9%]. Similarly at Week 52 more patients who applied ruxolitinib cream from Day 1 achieved VASI50 than those who switched over from vehicle after Week 24 (head and neck, 68·1% vs. 51·0%; hands, 38·2% vs. 29·2%; upper extremities, 56·7% vs. 34·9%; trunk, 48·4% vs. 25·4%; lower extremities, 54·5% vs. 32·3%; feet, 29·3% vs. 22·5%; total body [excluding face], 47·7% vs. 23·3%). Attainment of VASI50 at Week 52 among crossover patients (i.e. after 28 weeks of ruxolitinib cream) was consistent with Week 24 data in patients who applied ruxolitinib cream from Day 1. Adolescents and adults with NSV applying ruxolitinib cream achieved VASI50 in higher percentages compared with vehicle at Week 12 in the head and neck, upper extremities, trunk and lower extremities and at Week 24, regardless of the body region involved. The percentage of patients who achieved VASI50 increased through Week 52, including among patients who switched over from vehicle to ruxolitinib cream after Week 24. In summary, ruxolitinib cream produced a clinically meaningful re-pigmentation of all body regions (including hands and feet that are notoriously difficult to re-pigment) in TRuE-V1/TruE-V2 through Week 52, including among patients who switched over to ruxolitinib cream from vehicle after Week 24.

Vitiligo is an autoimmune skin disease mediated by autoreactive CD8+ T cells that destroy the pigmentproducing cells of the epidermis, melanocytes, leading to areas of depigmentation. Patients with vitiligo require lifelong treatment to regain and maintain their pigment. Clinical observations uncovered the importance of autoimmune memory in vitiligo because cessation of treatment frequently led to relapse of disease at the site of previous lesions. A subset of memory T cells known as CD8+ resident memory T cells (TRM) are long-lived, nonmigratory memory cells that persist in most nonlymphoid tissues, including the skin. Recent reports describe the presence of CD8+ TRM in lesional vitiligo patient skin and suggest their role as active players in disease maintenance. In this review, we will discuss the role of skin CD8+ TRM in maintaining disease in vitiligo and the opportunity to target this population to induce a long-lasting reversal of disease.

Background and Objectives Obesity is increasing among people residing in nursing homes, and resident obesity substantially affects services needed, equipment and facilities provided, and morbidity in this setting. The purpose of this article is to describe the scope and depth of evidence regarding the impact of obesity among nursing home residents in the United States. Research Design and Methods A systematic literature review was performed in PubMed, EMBASE, CINAHL, and Web of Science databases as well as additional hand-searched documents. Included articles were published from 1997 to March 2017. The characteristics and content of the included articles were systematically reviewed and reported. Results Twenty-eight studies met inclusion criteria for review. The median study size was 636 residents (interquartile range 40–11,248); 18 (64%) studies were retrospective and 10 (36%) were prospective in nature. Ten (36%) studies examined medical and functional morbidity, 10 (36%) examined health system effects, and 5 (18%) examined the risk of admission to nursing homes. Most studies found that obesity poses serious issues to resident health and the provision of health care, as well as broad health system and nursing challenges in the provision of high-quality nursing home care and services. Discussion and Implications Although obesity affects about one in four nursing home residents in the United States, relatively limited evidence exists on the complex challenges of obesity for their residents and their care. A continued focus on resident quality of life, health system improvement, and nursing best practices for properly caring for individuals with obesity is needed. [ABSTRACT FROM AUTHOR]

This paper theorizes that the impacts of land delivery and land holding mechanisms on the evolution and performance of informal light manufacturing clusters have been underexamined and need renewed evaluation for their impact on cluster performance and evolution of agglomeration effects. It examines 25 cases of African informal production clusters; 19 from existing studies, six previously unpublished to develop eight land delivery mechanism types and eight ways informal clusters hold urban land. The purpose is to provide a nuanced understanding of the mechanisms of land access for informal clusters so that future scholarship can investigate the impact of these mechanisms on informal production cluster evolution. The paper concludes with a resulting set of future research questions and implications for methods. [ABSTRACT FROM AUTHOR]

Background: Norovirus is the commonest cause of infectious intestinal disease (IID) worldwide. In the UK community incidence of norovirus has been estimated at 59/1000 population, equating to four million cases a year. Whilst norovirus infects people of all ages, a substantial burden occurs in infants and young children. The population of viruses found in sporadic cases among infants has been observed to be more diverse than that associated with outbreaks. In this study, we analysed norovirus-positive specimens collected during the second study of infectious intestinal diseases (IID2 Study) a national community cohort study conducted between April 2008 and August 2009 We examined the data for differences in circulating norovirus strains between two arms of a community cohort, and differences between genotypes and disease outcomes such as illness duration and symptom profiles.Methods: Analysis was conducted to assess genetic diversity of noroviruses in the community. We also assessed differences in the cycle threshold (Ct) value, as a proxy for viral load, between norovirus genogroups and genotypes, and differences in reported symptoms or length of illness in relation to genogroup and genotype.Results: There were 477 samples where norovirus was detected. Whilst 85% of people recovered within two days for vomiting; diarrhoea symptoms were reported to day 4 for 83% of the cases, and 10% of people reported symptoms of diarrhoea lasting between five and six days. Both diarrhoea and vomiting symptoms lasted longer in children aged < 5 years compared to adults. There was a significantly higher proportion of GII.4 in samples obtained from the GP arm of the study (chi-square = 17.8, p < 0.001) compared to samples received via post in the self-reporting arm. In the latter group, the prevalence of GII.6 was significantly higher (chi-square = 7.5, p < 0.001).Conclusions: We found that there is a difference in disease severity by age group. Children aged < 5 years had longer duration of illness, with 10% still having diarrhoea at seven days, and vomiting of between four and five days. The duration of illness reported is higher overall than one might expect for cases in the community in otherwise healthy individuals which has implications for infection control. No differences were observed in relation to duration of vomiting and or diarrhoea by genotype. [ABSTRACT FROM AUTHOR]

Abstract Background Obesity is recognized as a barrier to receiving women's preventive health services, including cervical and breast cancer screening. Little is known about whether obesity is associated with a lower incidence of human papillomavirus (HPV) vaccination, another important preventive care service for adolescent girls and young women. The objective of this study was to determine if adolescent girls and young women with obesity are less likely to receive HPV vaccination compared with individuals with normal weight. Methods We examined whether HPV vaccination was associated with obesity status in women aged 9–30 years surveyed from 2009 to 2016 by the U.S. National Health and Nutrition Examination Survey. Results from logistic and linear regression models were adjusted for age, race, income, insurance status, self-reported health, and health care use, accounting for the weighted survey design. Results The final cohort included 5,517 women. Overall, 32.9% of participants reported vaccination, with a mean age at vaccination of 15.8 years. Adolescent girls and young women with obesity were less likely to report vaccination; the adjusted odds ratio of vaccination was 0.79 (p =.01) compared with normal weight women. Among those vaccinated, the age at vaccination was significantly older for women with obesity, 16.3 years compared with 15.2 years (p =.002), but there was no difference in the completion of the vaccination series rate by obesity. Conclusions Adolescent girls and young women with obesity were less likely to report HPV vaccination and, if they were vaccinated, received the vaccination at a later age. [ABSTRACT FROM AUTHOR]

Using real-time wave packet propagation we consider the scattering properties of a linear collision system consisting of a harmonic oscillator coupled by truncated Morse potentials to two particles. This system is viewed as a model for the collision of a projectile D with a three particle target ABC with interactions such that the possible final states comprise backscattering of the projectile with the target intact, the ‘‘exchange’’ reaction ABC+D→A+BCD and the ‘‘fragmentation’’ reaction ABC+D→A+BC+D. For the types of interaction considered, the exchange reaction was found to proceed primarily via inelastic resonant processes and to be the dominant event for incident energies below the oscillator energy. Fragmentation occurred via nonresonant processes and dominated at higher energy. Other features of the scattering are discussed and compared with simple quantum theory and the description of the system given by classical mechanics. [ABSTRACT FROM AUTHOR]

The dynamics of activated associative desorption is discussed with particular reference to the system H2–Cu and to the partitioning of the energy released among the various product degrees of freedom. It is argued that a simple theory based on transition-state concepts should hold for this system because the potential energy surface (PES) divides naturally into reactant and product regions, separated by a ‘‘seam’’ or ‘‘ridge’’ at which it is reasonable to assume a thermal distribution of desorbing trajectories. Using a PES constructed in accordance with available electronic structure calculations we consider the angular distributions and translational, vibrational, and rotational energy distributions of the desorbing molecules. It is shown that, whereas the rotational energy reflects the surface temperature, the vibrational energy is markedly enhanced because the energetically low-lying regions of the ridge in the PES correspond to an H–H bond distance that is distended as compared with the gas-phase equilibrium separation. The enhancement is found to be a strong function of the surface temperature. The translational energy, however, is found to be only very weakly dependent on the temperature. These results are discussed in connection with available data. [ABSTRACT FROM AUTHOR]

This meant that the editorial workload increased, and I asked Tom Troscianko, who by then had joined Richard's lab, if he would become an assistant editor, and share the work. The author then appealed to Richard, who was uneasy, given the author's eminence, but to his credit supported his editors. Richard suggested that the decisions about publication were made by the reviewers rather than the editor and that the workload of an I Assistant Editor i would be light. [Extracted from the article]

The Ryder Cup is a biennial golf match between Europe and the USA that was staged in Wales for the first time in 2010. This article considers the representation of Wales within tourism texts through an analysis of the place of an individual. To date, little scholarship has examined the position of individuals within such discourse and explored the ways in which they can be (re) positioned as representative of a broader (supra)national configuration. In drawing upon the work of the cultural theorist Raymond Williams, it looks at narratives of Wales and the significance of an individual as relates to the interplay of nation, class and place. It argues that Ian Woosnam was centrally important as a 'Welsh European' in providing a physical and symbolic link to an event where no Welshman was a part of Team Europe. [ABSTRACT FROM AUTHOR]

This paper is based on a tutorial presented by the author as a part of the Minicourse on charged particle beams and high-powered pulsed sources given at the 2017 International Conference on Plasma Sciences at Atlantic City, NJ, USA. It is intended to provide a brief overview of the phenomenology and physics of the vacuum surface flashover process. These mechanisms will be used to motivate techniques commonly employed to improve the voltage standoff of insulators. In addition to serving as the primary limiting mechanism for vacuum insulators, vacuum surface flashover has a number of beneficial applications, primarily due to its ability to provide a simple pulsed plasma source, and a number of these applications will be discussed.

This paper presents the results of a seismic performance assessment using ASCE 41-13 for six buckling-restrained braced frames (BRBFs) designed in accordance with the 2012 International Building Code . The correlation between ASCE 7-10 and ASCE 41-13 is investigated to compare the seismic performance anticipated by the two standards. Three archetype buildings (4-, 8-, and 16-story) with BRBFs along one principal direction are designed for seismic effects: (1) once using the equivalent lateral force (ELF) procedure and (2) a second time using the response spectrum analysis (RSA) procedure. Performance assessments are conducted using four analysis procedures, static and dynamic analyses performed under both linear and nonlinear analysis regimes. Linear analysis results indicate minor performance deficiencies in the columns and the braces. Surprisingly, the nonlinear analysis results indicate more performance deficiencies in the braces, which is opposite of the general expectation that a more sophisticated analysis would yield a less conservative result. The contributing factors to the performance deficiencies are investigated. Recommendations are made on how to alter the performance outcome such as using alternative ground motion selection approaches (e.g., conditional mean spectrum) and having acceptance criteria based on cumulative ductility demands.

An electron beam traversing a slow wave structure can be used to either generate or amplify electromagnetic radiation through the interaction of the slow space charge wave on the beam with the slow wave structure modes. Here, a cylindrical waveguide with a periodic array of conducting loops is used for the slow wave structure. This paper considers operation as a backward wave oscillator. The dispersion properties of the structure are determined using a frequency-domain eigenmode solver. The interaction of the electron beam with the structure modes is investigated using a 2-D particle-in-cell (PIC) code. The operating frequency and growth rate dependence on beam energy and beam current are investigated using the PIC code and compared with analytic and scaling estimates where possible [ABSTRACT FROM AUTHOR]

The article reviews research literature on the use of community-based surveillance systems to obtain information on norovirus disease. Topics include techniques for the estimate of incidence rates of norovirus and gastroenteritis, estimates of the hospitalization of children related to norovirus diseases, and the age-specific nature of estimates from community-based surveillance systems.

Objectives To determine the difference in receipt of activity of daily living ( ADL) assistance between obese and normal-weight older adults. Design Retrospective cohort study. Setting National Health and Aging Trends Study, 2011-2015. Participants U.S. adults aged 65 and older with ADL disability and a body mass index ( BMI) of 18.5 kg/m2 or greater (N = 5,612) Measurements BMI was classified as normal weight (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), or obese (≥30.0 kg/m2). Primary outcome was self-reported receipt of help with specific ADLs. Models were adjusted for demographic characteristics (age, sex, race), degree of need (self-reported general health, severity of disability), household resources (income, marriage, people in household, number of children), and cognitive status (dementia, proxy respondent). Results Obese with disabilities had lower rates of receiving assistance with walking inside (odds ratio ( OR) = 0.63, 95% confidence interval ( CI) = 0.50-0.81), walking outside ( OR = 0.76, 95% CI = 0.59-0.97), toileting ( OR = 0.68, 95% CI = 0.52-0.89), and getting in and out of bed ( OR = 0.67, 95% CI = 0.50-0.87) than normal-weight older adults after adjustment for respondent demographic characteristics. Level of need and cognitive status partially explained the associations. In fully adjusted models, older adults with obesity still had significantly lower odds of receiving assistance in getting in and out of bed than normal weight adults ( OR = 0.69, 95% CI = 0.49-0.98). Conclusion Older adults with obesity are less likely to receive assistance for ADL disabilities than their normal-weight counterparts-an important concern because of ongoing demographic changes in the United States.

The article explores the use of Biblical allusions in the plays of William Shakespeare. Emphasis is given to references to marginal notes of the Geneva Bible in plays such as "Cymbeline," "Hamlet," and "The Rape of Lucrece." Other topics include the figurative use of margins as sources of meaning and tongues as weapons.

Purpose: The purpose of this study was to investigate the moderating effect of perceived resource availability on the relationship between work passion and employee well-being (i.e., job satisfaction and job tension) and performance (i.e., job performance and citizenship behaviors) using self-determination theory. Design/Methodology/Approach: Data were obtained through surveys distributed via an online platform (Sample 1) and to employees of three professional organizations: a municipal agency (Sample 2), an engineering firm (Sample 3), and an advertising organization (Sample 4). Findings: The interaction between employees' work passion and their perceptions of available resources was associated with employees' well-being and performance, such that greater work passion was associated with positive outcomes when resources were perceived as available. Conversely, heightened work passion was associated with job tension and fewer positive benefits when perceived available resources were low. Implications: Work passion is often touted by employers as a valuable characteristic for employees, but, as these findings suggest, there are conditions that must be met in order for employees to experience positive well-being and performance outcomes. This information will likely prove invaluable for those employers seeking to best support their passionate employees. Originality/Value: Research into the area of work passion is small but growing, and this study provides valuable insight into a key boundary condition for the effectiveness of passion: perceived resource availability. Additionally, this study identifies circumstances in which passionate employees actually experience a negative work outcome. Further, the multiple samples and constructive replication employed help provide confidence and a strong empirical foundation for the results. [ABSTRACT FROM AUTHOR]
