Dental students’ perceived and actual knowledge of elder abuse: An online training curriculum
Authors: Nouer Simonne S. , Meyer Laura , Shen Yan , Hare Marion E. , Connor Pamela D. 
Published: December 2019

AbstractAimsElder abuse, defined as emotional, physical, or sexual abuse, financial exploitation, or neglect, is a growing problem. Dental professionals have the unique opportunity to identify elder abuse. However, elder abuse awareness training, targeting dental students, is insufficient and research is limited. This knowledge gap prompted the research team at the University of Tennessee Health Science Center (UTHSC) to develop, implement, and evaluate an online Elder Abuse Awareness Professional Education Training (EAAPET) program, designed to educate dental and other health professionals to recognize, respond to, and report elder abuse.Methods and ResultsNinety‐six dental students, attending the UTHSC College of Dentistry during the fall semester of 2018, were enrolled. Pre‐ and post‐assessments, designed to assess changes in students’ perceived and actual knowledge, were conducted. Paired sample t‐test results indicate that the EAAPET program significantly improved students’ perception of their abilities to identify, respond to, and report elder abuse. Improvement was also demonstrated within students’ actual knowledge of how to appropriately interact with suspected elder abuse victims. Qualitative assessment suggested the training was well received by the students.ConclusionsBased on these findings, the authors recommend that dental schools integrate elder abuse awareness education into their curriculums.
Do you feel like an insider? Job security and preferences for Flexibilization across Europe
Authors: Duman Anil , Kemmerling Achim 
Published: December 2019

AbstractThe paper analyses the determinants of public opinion on flexibilisation of work contracts. While the literature on new labour market divides has rapidly expanded, few contributions directly look at employees’ demands for labour market regulation. By using a multi‐level data set for 25 European countries, we find that the subjectively assessed job security is an important and valuable predictor of preferences for flexibilisation. In particular, those with very low and very high levels of perceived job security prefer flexibilisation compared to those with medium levels. We also show that the effect is stronger in countries with stricter employment protection legislation. The findings contribute to the literature on new divides of labour market politics in several ways. First, our empirical operationalization is related directly to the core of insider‐outsider theory, the protection of work contracts. Second, subjective assessment of employment security yields important complementary insights into a debate usually focusing on objective measures. Third, we find that the (subjective) divide is context dependent; it is much more visible in countries where employment protection regulation is strong.
Stifling Workplace Activism: The Consequences of Anthem Protests for NFL Players
Authors: Niven David 
Published: December 2019

ObjectiveTracking the future contract status of NFL players affords a rare opportunity to test whether there were repercussions for participating in the 2017 national anthem protest and whether more vulnerable players were right to be wary of the owners’ wrath.MethodsA sample of NFL players with comparable performance is used to compare how protesters and nonprotesters were treated in their next contract.ResultsData reveal distinct differences in treatment between NFL players who protested and those who did not. In short, protesters were more likely to take a pay cut, see their salaries grow at a lower rate, and were more likely to be sent to another team.ConclusionThe results suggest the need for critics to acknowledge the real career consequences athletes can face for political activism. Moreover, if NFL players—who work in the public eye, hold proven track records of accomplishment, and compete in a market that prides itself on analytic efficiency—can be punished by their employers for political activism, it suggests the truly profound vulnerability of everyday workers who labor without those advantages.
Explaining Gender Differences in Turnout Using Panel Data Across Elections
Authors: Coffé Hilde , Lago Ignacio 
Published: December 2019

ObjectivesThe current study offers the first systematic analysis of the impact of citizens’ interest in and perceptions of specific elections on gender differences in turnout.MethodsUsing an Internet panel survey conducted by the Making Electoral Democracy Work project covering the 2013 state, 2013 federal, and 2014 European elections in Bavaria (Germany), our probit models examine mediation and moderation effects of three election‐related characteristics: the issues that citizens consider most central in the elections, citizens’ interest in the elections, and the perceived influence among citizens of the policies of the different levels of policy making on their well‐being.ResultsThe results indicate an overall gender difference in turnout in Bavaria with women being less likely to vote compared with men. Yet, this gender effect ceases to be significant once citizens’ attitudes toward and perceptions of specific elections are controlled for. Interest in the election at hand has a particularly strong and positive effect on the likelihood of voting. We find no significant gender interactions.ConclusionCitizens' interest in and perceptions of specific elections have a strong impact on turnout and gender differences therein.

AbstractThere has been little surveillance of influenza A viruses (IAVs) circulating in swine at live animal markets, particularly in the United States. To address this gap, we conducted active surveillance of IAVs in pigs, the air, and the environment during a summer and winter season in a live animal market in St. Paul, Minnesota, that had been epidemiologically associated with swine‐origin influenza cases in humans previously. High rates of IAV were detected by PCR in swine lungs and oral fluids during both summer and winter seasons. Rates of IAV detection by PCR in the air were similar during summer and winter, although rates of successful virus isolation in the air were lower during summer than in winter (26% and 67%, respectively). H3N2 was the most prevalent subtype in both seasons, followed by H1N2. Genetically diverse viruses with multiple gene constellations were isolated from both winter and summer, with a total of 19 distinct genotypes identified. Comparative phylogenetic analysis of all eight segments of 40 virus isolates from summer and 122 isolates from winter revealed that the summer and winter isolates were genetically distinct, indicating IAVs are not maintained in the market, but rather are re‐introduced, likely from commercial swine. These findings highlight the extent of IAV genetic diversity circulating in swine in live animal markets, even during summer months, and the ongoing risk to humans.
Research on the Performance of a Vertical-Axis Wind Turbine With Helical Blades by Detached Eddy Simulation
Authors: Liu Xiaolan , Chen Qian , Yang Bo , Song Moru 
Published: December 2019

Abstract
In this paper, due to its advantages of high accuracy and moderate computational cost, detached eddy simulation (DES) is adopted to observe detail flow characteristics of a kind of vertical axial wind turbine equipped with four helical blades. The numerical results obtained from the method have been validated by experiments as well as been compared with those from unsteady Reynolds-averaged Navier–Stokes equations (U-RANS). Several critical parameters, such as the torque, power coefficient, and tangential force, are studied in detail. It is found that the results from DES are closer to the measurement data than those from U-RANS. And, the characteristics of the flow field in the turbine can be clearly revealed by DES. Furthermore, the effects of tip vortex, Reynolds number, and pitch angle on turbine performance have also been analyzed and discussed.

Authors: Ye Honglie , Zheng Yanjie , Zheng Hongfei , Liang Shen 
Published: December 2019

Abstract
In this paper, a new design of a solar still powered by a compound parabolic concentrator (CPC-SS) for agriculture irrigation is proposed and investigated. The concentrating performance of its concentrator is simulated which is proved that it has a wide focusing angle and the receiving rate is still more than 80% when the incident angle of light reaches to 35 deg. Theoretical calculations show that the daily water production rate per unit area of the solar still can reach 4 kg/m2, which can meet the crop growth needs of 2 m2. The water production performance and operating temperature of the CPC-SS were tested experimentally under actual weather conditions, and the variation curves of system internal working temperature and water production performance with time were given. As the results, in the sunny weather conditions in Beijing in the autumn, the daily water production of the tubular solar still is about 2.03 kg/m2, and the maximum operating temperature in the tube reaches 60 °C. The actual solar energy utilization efficiency can be as high as 22%.

Published: December 2019

Abstract
In order to solve the problem of the unclear understanding of the water cone behavior and its influencing factors of horizontal well in a heavy oil reservoir with bottom water, in this paper, a series of physical models were established to quantitatively describe the inner relationships between them and further illustrated their influence on the water-cut increasing law. The results showed that the water cone and water-cut grew quickly in the heavy oil reservoir with bottom water. The sweep efficiency of the basic 2D sand-pack model reaches 0.68. The decrement of crude oil viscosity increases the sweep efficiency to about 0.08. The increment of production pressure drop increases the sweep efficiency to about 0.05–0.07. Heterogeneity enhancement decreases the sweep efficiency to about 0.06. The addition of adjustment well and barriers increases the sweep efficiency to about 0.20 and 0.08, respectively. The final sweep efficiency of the whole water cone in the 3D sand-pack model reaches 0.42. Finally, we found that the water-cut increment rules are mainly affected by water cone behavior, production schedule, and the location and distribution of barriers. The study in this paper lays a foundation for the rational and effective development of heavy oil reservoirs with bottom water, which has a broad field application prospects in the future.
Analytical Study of the Snap-Through and Bistability of Beams With Arbitrarily Initial Shape
Authors: Hussein Hussein , Younis Mohammad I. 
Published: December 2019

Abstract
We derive the snap-through solution and the governing snapping force equations for an arbitrarily preshaped beam deflected under a mid-length lateral point force. The exact solution is obtained based on the classical theory of elastic beams as a superposition of the initial shape and the modes of buckling. Two kinds of solutions are identified depending on the axial force level. The two solutions, bifurcation conditions, bistability conditions, and the snapping force equations are derived and discussed. The snap-through and snapping force solutions are then calculated for two common beam initial shapes, the curved (first buckling shape) and the inclined one (V-shape). In both cases, explicit expressions are obtained describing the snap-through behavior. The analytical modeling results show excellent agreement with finite element simulations. The comparison between the two cases shows a similar snap-through behavior qualitatively, while several differences and similarities are noticed quantitatively.

Published: December 2019

Abstract
Spasticity is a hypertonic muscle behavior commonly observed in patients with multiple sclerosis, cerebral palsy, stroke, etc. Clinical assessment for spasticity is done through passive stretch evaluations of various joints using qualitative clinical scales, such as the Modified Ashworth Scale (MAS). Due to the subjective nature of this evaluation method, diagnostic results can have poor reliability and inconsistency. A few research groups have developed electromechanical training simulators of upper arm spasticity with the intent of providing healthcare students practical training opportunities. This paper presents a novel, purely mechanical (nonpowered) training simulator as an alternative design approach. This passive design utilizes a hydraulic damper with selectable viscous effect to simulate the speed-dependent spastic muscle tone and a Scotch-Yoke linkage system to create the “catch-release” behavior of spasticity. An analytical fluid model was developed to systematically design the hydraulic damper. The error residuals between model prediction and experimental damping force were found within ±2.0 N and percent errors within ±10% across various testing speeds (i.e., 250, 500, 750, and 1000 mm/min). The performance of the fully assembled simulator was tested under slow (ω ≤ 60 deg/s), medium (60 deg/s &lt; ω &lt; 150 deg/s), and fast (ω ≥ 150 deg/s) stretch speeds, where ω is the joint angular speed. Preliminary bench-top results suggested the feasibility of replicating five distinct levels of spasticity behaviors (MAS levels 0–4), where resistive torque increased with higher stretch speed and peak resistive torque ranged from 1.3 to 6.7 N · m under the fast stretch speed.

Published: December 2019

Although much has been learned about the workplace experiences of physical education teachers, less is known about the unique experiences of adapted physical educators (APEs). Grounded in role socialization theory, the purpose of this study was to understand the relationships among perceived organizational support, resilience, perceived mattering, emotional exhaustion, and job satisfaction in APEs. The participants included 237 APEs from the United States, who completed an online survey. The primary data analyses included confirmatory factor analysis and structural equation modeling. The final structural model was a good fit for the data, χ2(199) = 327.25, p < .001, χ2/df = 1.64; root-mean-square error of approximation = .052 (90% confidence interval [.042, .062], p = .354); standardized root-mean-square residual = .050; nonnormed fit index = .959; comparative-fit index = .964. The results of this study highlight the importance of developing a workplace environment in which APEs feel supported in developing perceptions of matter, reducing emotional exhaustion, and improving job satisfaction.

Published: December 2019

ObjectiveTo describe infants with acute gastroenteritis symptoms in primary and secondary care who have the Rotarix vaccine-derived G1P[8] rotavirus strain identified in their stools.DesignThis is a prospective national surveillance conducted by Public Health England (PHE). Rotavirus-positive samples from vaccine-eligible children are routinely submitted to PHE for confirmation, and general practitioners are requested to complete a surveillance questionnaire for all cases. The modified Vesikari Score was used to assess severity of gastroenteritis.SettingEngland, July 2013–September 2016.Results2637 rotavirus strains were genotyped and 215 (8%) identified as the Rotarix vaccine-derived G1P[8] strain. There were no Rotarix vaccine-derived G1P[8] strains detected in unimmunised infants. Rotarix vaccine-derived G1P[8] strains clustered around the time of rotavirus vaccination and were responsible for 82% (107 of 130) of rotavirus-positive samples in 2-month-old infants and 68% (36 of 53) in 3-month-old infants. However, 13 samples were obtained more than 7 weeks after the last vaccination date; 10 of these specimens were from six children who were subsequently diagnosed with severe combined immunodeficiency (SCID). Diarrhoea was the single most common presenting symptom (83.0%) in infants with Rotarix vaccine-derived G1P[8] strains, who were less likely to present with fever, vomiting, dehydration or severe gastroenteritis than infants with wild-type rotavirus infection.ConclusionsRotavirus identified in stools of infants around the time of their routine immunisations is most likely the Rotarix vaccine-derived G1P[8] strain. Infants with undiagnosed SCID at the time of rotavirus immunisation may experience prolonged gastroenteritis symptoms. Most infants with vaccine strains in their stools more than 7 weeks after immunisation had SCID.

Published: December 2019

ObjectiveTo identify how causative agents and mechanisms of injury influence the location of an accidental contact burn in children and whether these factors differ in cases referred for child protection (CP) assessment.DesignProspective multicentre cross-sectional study.Setting20 hospital sites across England and Wales, including: emergency departments, minor injury units and regional burn units.PatientsChildren less than 5 years old who attended hospital for a contact burn (August 2015 to September 2018).Main outcome measuresLocation of burns with respect to agent and mechanism for accidental contact burns. Secondary outcome: mechanism, agent and location of burns referred for CP assessment.Results816 accidental burns and 92 referrals for CP assessment. The most common for accidental burns: mechanism was reaching while stationary (68%, 553/816), agent was oven (24.5%, 200/816) and site was the hand (69.2%, 565/816). Burns to head and trunk were rare at 3.7% (30/816). The data enabled a tabulation of the locations of burns as predicted by agent and mechanism of injury. The location of the burn was most strongly influenced by mechanism.Burns from irons (p<0.01), caused by mechanisms independent of the child (p=0.01), unwitnessed burns (p<0.001) and burns to the head and trunk (p<0.001) were significantly more common among the children referred for CP assessment.ConclusionsBy overlaying agent, mechanism and site it was possible to tabulate and quantify simple narratives of accidental contact burns in population of young children. These findings have the potential to aid clinicians in recognising accidental contact burns.

ObjectiveTo evaluate the diagnostic accuracy of transthoracic echocardiography (TTE) in patients with pulmonary hypertension (PH).DesignSystematic review and meta-analysis.Data sources and eligibility criteriaEmbase, Cochrane Library for clinical trials, PubMed and Web of Science were used to search studies from inception to 19 June, 2019. Studies using both TTE and right heart catheterisation (RHC) to diagnose PH were included.Main resultsA total of 27 studies involving 4386 subjects were considered as eligible for analysis. TTE had a pooled sensitivity of 85%, a pooled specificity of 74%, a pooled positive likelihood ratio of 3.2, a pooled negative likelihood ratio of 0.20, a pooled diagnostic OR of 16 and finally an area under the summary receiver operating characteristic curve of 0.88. The subgroup with the shortest time interval between TTE and RHC had the best diagnostic effect, with sensitivity, specificity and area under the curve (AUC) of 88%, 90% and 0.94, respectively. TTE had lower sensitivity (81%), specificity (61%) and AUC (0.73) in the subgroup of patients with definite lung diseases. Subgroup analysis also showed that different thresholds of TTE resulted in a different diagnostic performance in the diagnosis of PH.ConclusionTTE has a clinical value in diagnosing PH, although it cannot yet replace RHC considered as the gold standard. The accuracy of TTE may be improved by shortening the time interval between TTE and RHC and by developing an appropriate threshold. TTE may not be suitable to assess pulmonary arterial pressure in patients with pulmonary diseases.PROSPERO registration numberPROSPERO CRD42019123289.

ObjectiveIdentification of older patients at risk, among those accessing the emergency department (ED), may support clinical decision-making. To this purpose, we developed and validated the Dynamic Silver Code (DSC), a score based on real-time linkage of administrative data.Design and settingThe ‘Silver Code National Project (SCNP)’, a non-concurrent cohort study, was used for retrospective development and internal validation of the DSC. External validation was obtained in the ‘Anziani in DEA (AIDEA)’ concurrent cohort study, where the DSC was generated by the software routinely used in the ED.ParticipantsThe SCNP contained 281 321 records of 180 079 residents aged 75+ years from Tuscany and Lazio, Italy, admitted via the ED to Internal Medicine or Geriatrics units. The AIDEA study enrolled 4425 subjects aged 75+ years (5217 records) accessing two EDs in the area of Florence, Italy.InterventionsNone.Outcome measuresPrimary outcome: 1-year mortality. Secondary outcomes: 7 and 30-day mortality and 1-year recurrent ED visits.ResultsAdvancing age, male gender, previous hospital admission, discharge diagnosis, time from discharge and polypharmacy predicted 1-year mortality and contributed to the DSC in the development subsample of the SCNP cohort. Based on score quartiles, participants were classified into low, medium, high and very high-risk classes. In the SCNP validation sample, mortality increased progressively from 144 to 367 per 1000 person-years, across DSC classes, with HR (95% CI) of 1.92 (1.85 to 1.99), 2.71 (2.61 to 2.81) and 5.40 (5.21 to 5.59) in class II, III and IV, respectively versus class I (p<0.001). Findings were similar in AIDEA, where the DSC predicted also recurrent ED visits in 1 year. In both databases, the DSC predicted 7 and 30-day mortality.ConclusionsThe DSC, based on administrative data available in real time, predicts prognosis of older patients and might improve their management in the ED.
