Proton Pump Inhibitor Use Is Associated With a Reduced Risk of Infection with Intestinal Protozoa
Authors: Sheele Johnathan M. 
Published: September 2017

Objective Proton pump inhibitors (PPIs) can kill some human protozoan parasites in cell culture better than the drug metronidazole. Clinical data showing an antiprotozoal effect for PPIs are lacking. The objective of the study is to determine if PPI use is associated with a reduced risk of having intestinal parasites. Methods We obtained electronic medical record data for all persons who received a stool ova and parasite (O & P) examination at our tertiary care academic medical center in Cleveland, Ohio, between January 2000 and September 2014. We obtained the person’s age, whether they were taking a PPI at the time of the O & P examination, and whether the pathology report indicated the presence of any parasites. χ2 with Yates correction was used to determine if PPI use was associated with stool protozoa. Results Three intestinal protozoa were identified in 1199 patients taking a PPI (0.3%), and 551 intestinal parasites were identified in the 14,287 patients not taking a PPI (3.9%). There was a statistically significant lower likelihood of finding protozoa in the stool of a person taking a PPI compared with those not taking a PPI ( P < .0001). Conclusions Patients taking a PPI were statistically less likely to have an intestinal protozoa reported on stool O & P examination compared with those not taking a PPI.
WHAT THE (EXPLETIVE) IS A “CONSTITUTION”?! ORDINARY CADRES CONFRONT THE 1954 PRC DRAFT CONSTITUTION
Authors: Diamant Neil J. 
Published: September 2017

AbstractFollowing the history of western constitutional history, studies of Chinese constitutionalism have tended to focus on its intellectual origins, or, more commonly these days, its failure to restrain official behavior. Drawing upon new archival materials, this article takes a different tack. I zero in on a critical period of constitutional gestation, when officials read the 1954 constitution in draft form, posed questions about its text and suggested revisions. How did officials react when told that citizens, many of whom were recently persecuted, now enjoy “freedom of assembly”? These materials allow us to see “the state” in real time: How did officials understand core legal concepts such as “right,” “constitution” and “citizen” as well as their role in the new polity? In many respects, the discussion surrounding the draft constitution turned out to be a venue for officials to talk about the meaning of the revolution they had just experienced.
CARNIVAL AND SACRED DRAMA: SCHÜTZ’SCHRISTMAS HISTORIAAND THE TRANSFORMATION OF CHRISTMAS IN THE SECOND HALF OF THE SEVENTEENTH CENTURY
Authors: Rathey Markus 
Published: September 2017

The celebration of Christmas in Early Modern Europe underwent a significant transformation in the second half of the seventeenth century. Even after the Protestant Reformation, European Christmas traditions maintained numerous features of their medieval practices, such as carnivalesque celebrations, processions, masks, and riotous behaviour. This changed during the seventeenth century. Popular carnivalesque Christmas plays were prohibited and replaced with a more internalized devotion that emphasized the individual’s relationship with the newborn Child. This transformation was part of a larger paradigm shift in seventeenth-century religiosity, which replaced external and physical displays of piety with internalized devotional practices. These shifts also included new theologies of corporeality and gender, which likewise had an impact on the ways in which Christmas was celebrated. The theological shifts correlate with the rejection of the carnivalesque in the Early Modern period, as it was analysed by Mikhail Bakhtin.Most of these changes took place in the 1670s and 1680s. Schütz’s Christmas Historia – which was composed before 1664 – represents a transitional phase and retains some earlier views of Christmas. The most obvious example is the Kindelwiegen (rocking of the child), the physicality of which was highly suspicious to theologians in the later seventeenth century. Schütz not only refers to this practice but incorporates it in the texture of his music.

AbstractObjectiveEnsuring ready access to free drinking-water in schools is an important strategy for prevention of obesity and dental caries, and for improving student learning. Yet to date, there are no validated instruments to examine water access in schools. The present study aimed to develop and validate a survey of school administrators to examine school access to beverages, including water and sports drinks, and school and district-level water-related policies and practices.DesignSurvey validity was measured by comparing results of telephone surveys of school administrators with on-site observations of beverage access and reviews of school policy documents for any references to beverages. The semi-structured telephone survey included items about free drinking-water access (sixty-four items), commonly available competitive beverages (twenty-nine items) and water-related policies and practices (twenty-eight items). Agreement between administrator surveys and observation/document review was calculated using kappa statistics for categorical variables, and Pearson correlation coefficients and t tests for continuous variables.SettingPublic schools in the San Francisco Bay Area, California, USA.SubjectsSchool administrators (n 24).ResultsEighty-one per cent of questions related to school beverage access yielded κ values indicating substantial or almost perfect agreement (κ>0·60). However, only one of twenty-eight questions related to drinking-water practices and policies yielded a κ value representing substantial or almost perfect agreement.ConclusionsThis school administrator survey appears reasonably valid for questions related to beverage access, but less valid for questions on water-related practices and policies. This tool provides policy makers, researchers and advocates with a low-cost, efficient method to gather national data on school-level beverage access.
Physiotherapy-as-first-point-of-contact-service for patients with musculoskeletal complaints: understanding the challenges of implementation
Authors: Moffatt Fiona , Goodwin Rob , Hendrick Paul 
Published: September 2017

Background
Primary care faces unprecedented challenges. A move towards a more comprehensive, multi-disciplinary service delivery model has been proposed as a means with which to secure more sustainable services for the future. One seemingly promising response has been the implementation of physiotherapy self-referral schemes, however there is a significant gap in the literature regarding implementation.

Aim
This evaluation aimed to explore how the professionals and practice staff involved in the delivery of an in-practice physiotherapy self-referral scheme understood the service, with a focus on perceptions of value, barriers and impact.

Design and setting
A qualitative evaluation was conducted across two UK city centre practices that had elected to participate in a pilot self-referral scheme offering ‘physiotherapy-as-a-first-point-of-contact’ for patients presenting with a musculoskeletal complaint.

Methods
Individual and focus group interviews were conducted amongst participating physiotherapists, administration/reception staff, general practitioners (GPs) and one practice nurse (in their capacity as practice partner). Interview data were collected from a total of 14 individuals. Data were analysed using thematic analysis.

Results
Three key themes were highlighted by this evaluation. First, the imperative of effecting a cultural change – including management of patient expectation with particular reference to the belief that GPs represented the ‘legitimate choice’, re-visioning contemporary primary care as a genuine team approach, and the physiotherapists’ reconceptualisation of their role and practices. Second, the impact of the service on working practice across all stakeholders – specifically re-distribution of work to ‘unburden’ the GP, and the critical role of administration staff. Finally, beliefs regarding the nature and benefits of physiotherapeutic musculoskeletal expertise – fears regarding physiotherapists’ ability to work autonomously or identify ‘red flags’ were unfounded.

Conclusion
This qualitative evaluation draws on the themes to propose five key lessons which may be significant in predicting the success of implementing physiotherapy self-referral schemes.
MHD simulations of coronal dark downflows considering thermal conduction

Published: September 2017

AbstractWhile several scenarios have been proposed to explain supra-arcade downflows (SADs) observed descending through turbulent hot regions, none of them have systematically addressed the consideration of thermal conduction. The SADs are known to be voided cavities. Our model assumes that SADs are triggered by bursty localized reconnection events that produce non-linear waves generating the voided cavity. These subdense cavities are sustained in time because they are hotter than their surrounding medium. Due to the low density and large temperature values of the plasma we expect the thermal conduction to be an important process. Our main aim here is to study if it is possible to generate SADs in the framework of our model considering thermal conduction. We carry on 2D MHD simulations including anisotropic thermal conduction, and find that if the magnetic lines envelope the cavities, they can be isolated from the hot environment and be identified as SADs.
Modelling short-term Solar Spectral Irradiance (SSI) using coronal electron density and temperature profiles based on solar magnetic field observations

Published: September 2017

AbstractSome key physical processes that impact the evolution of Earth's atmosphere on time-scale from days to millennia, such as the EUV emissions, are determined by the solar magnetic field. However, observations of the solar spectral irradiance are restricted to the last few solar cycles and are subject to large uncertainties. We present a physics-based model to reconstruct short-term solar spectral irradiance (SSI) variability. The coronal magnetic field is estimated to employ the Potential Field Source Surface extrapolation (PFSS) based on observational synoptic charts and magnetic flux transport model. The emission is estimated to employ the CHIANTI atomic database 8.0. The performance of the model is compared to the emission observed by TIMED/SORCE.

Published: September 2017

AbstractThis work presents the first results of a study about possible effects on the surface temperature during short periods of lower fluxes of Galactic Cosmic Rays at Earth, called Forbush Decreases. There is a hypothesis that the Galactic Cosmic Ray flux decreases cause changes on the physical-chemical properties of the atmosphere. We have conducted a study to investigate these possible effects on several latitudinal regions, around the ten strongest FDs occurred from 1987 to 2015. We have found a possible increase on the surface temperature at middle and high latitudes during the occurence of these events.

Published: September 2017

AbstractThe characterization of short-period detached low-mass binaries, by the determination of their physical and orbital parameters, reveal the most precise basic parameters of low-mass stars. Particularly, when photometric and spectroscopic data of eclipsing binaries (EBs) are combined. Recently, 16 new low-mass EBs were discovered by the WFCAM Transit Survey (WTS), however, only three of them were fully characterized. Therefore, new spectroscopic data were already acquired with the objective to characterize five new detached low-mass EBs discovered in the WTS, with short periods between 0.59 and 1.72 days. A preliminary analysis of the radial velocity and light curves was performed, where we have derived orbital separations of 2.88 to 6.69 R⊙, and considering both components, we have found stellar radii ranging from 0.40 to 0.80 R⊙, and masses between 0.24 and 0.71 M⊙. In addition to the determination of the orbital parameters of these systems, the relation between mass, radius and orbital period of these objects can be investigated in order to study the mass-radius relationship and the radius anomaly in the low main-sequence.

Published: September 2017

AbstractThe Calar Alto Secondary Eclipse study was a program dedicated to observe secondary eclipses in the near-IR of two known close-orbiting exoplanets around K-dwarfs: WASP-10b and Qatar-1b. Such observations reveal hints on the orbital configuration of the system and on the thermal emission of the exoplanet, which allows the study of the brightness temperature of its atmosphere. The observations were performed at the Calar Alto Observatory (Spain). We used the OMEGA2000 instrument (Ks band) at the 3.5m telescope. The data was acquired with the telescope strongly defocused. The differential light curve was corrected from systematic effects using the Principal Component Analysis (PCA) technique. The final light curve was fitted using an occultation model to find the eclipse depth and a possible phase shift by performing a MCMC analysis. The observations have revealed a secondary eclipse of WASP-10b with depth of 0.137%, and a depth of 0.196% for Qatar-1b. The observed phase offset from expected mid-eclipse was of −0.0028 for WASP-10b, and of −0.0079 for Qatar-1b. These measured offsets led to a value for |ecosω| of 0.0044 for the WASP-10b system, leading to a derived eccentricity which was too small to be of any significance. For Qatar-1b, we have derived a |ecosω| of 0.0123, however, this last result needs to be confirmed with more data. The estimated Ks-band brightness temperatures are of 1647 K and 1885 K for WASP-10b and Qatar-1b, respectively. We also found an empirical correlation between the (R′HK) activity index of planet hosts and the Ks-band brightness temperature of exoplanets, considering a small number of systems.
Estimating the chromospheric magnetic field from a revised NLTE modeling: the case of HR 7428
Authors: Busá Innocenza 
Published: September 2017

AbstractSemi-empirical atmospheric modeling is here used to obtain the chromospheric magnetic field distribution versus height in the K2 primary component of the RS CVn binary system HR 7428. The chromospheric magnetic field estimation versus height comes from considering the possibility of not imposing hydrostatic equilibrium in the atmospheric modeling. The stability of the best Non-hydrostatic equilibrium model, implies the presence of and additive (toward the center of the star) pressure, that decrease in strength from the base of the chromosphere toward the outer layers. Interpreting the additive pressure as magnetic pressure and I derive a magnetic field intensity of about 500 Gauss at the base of the chromosphere.

Published: September 2017

AbstractIn 1964 (Solar Cycle 20; SC 20), Patrick McIntosh began creating hand-drawn synoptic maps of solar magnetic features, based on Hα images. These synoptic maps were unique in that they traced magnetic polarity inversion lines, and connected widely separated filaments, fibril patterns, and plage corridors to reveal the large-scale organization of the solar magnetic field. Coronal hole boundaries were later added to the maps, which were produced, more or less continuously, into 2009 (i.e., the start of SC 24). The result was a record of ~45 years (~570 Carrington rotations), or nearly four complete solar cycles of synoptic maps. We are currently scanning, digitizing and archiving these maps, with the final, searchable versions publicly available at NOAA's National Centers for Environmental Information. In this paper we present preliminary scientific studies using the archived maps from SC 23. We show the global evolution of closed magnetic structures (e.g., sunspots, plage, and filaments) in relation to open magnetic structures (e.g., coronal holes), and examine how both relate to the shifting patterns of large-scale positive and negative polarity regions.

Published: September 2017

AbstractThe Io Plasma Torus (IPT) is a doughnut-shaped structure of charged particles, composed mainly of sulfur and oxygen ions. The main source of the IPT is the moon Io, the most volcanically active object in the Solar System. Io is the innermost of the Galilean moons of Jupiter, the main source of the magnetospheric plasma and responsible for injecting nearly 1 ton/s of ions into Jupiter's magnetosphere. In this work ground-based observations of the [SII] 6731 Å emission lines are observed, obtained at the MacMath-Pierce Solar Telescope. The results shown here were obtained in late 1997 and occurred shortly after a period of important eruptions observed by the Galileo mission (1996-2003). Several outbursts were observed and periods of intense volcanic activity are important to correlate with periods of brightness enhancements observed at the IPT. The time of response between an eruption and enhancement at IPT is still not well understood.

Published: September 2017

AbstractThe catalog of 38,000 chromospherically active RAVE dwarfs represents one of the largest samples of young active solar-like and later-type single field stars in the Solar neighbourhood. It was established from the unbiased magnitude limited RAVE Survey using an unsupervised stellar classification algorithm based merely on stellar fluxes (Ca II infrared triplet). Using a newly-calibrated age-activity relation, ~15,000 active stars are estimated to be younger than 1 Gyr. Almost 2000 stars are presumably younger than ~100 Myr and possibly still in the pre-main sequence phase, the latter being supported by their significant offset from the main sequence in the NUV − V versus J − K space. 16,000 stars from the sample have positional and velocity vectors available (using TGAS parallaxes and proper motions and radial velocities from RAVE).
Understanding the connection between the energy released during solar flares and their emission in the lower atmosphere
Authors: da Costa F. Rubio 
Published: September 2017

AbstractWhile progress has been made on understanding how energy is released and deposited along the solar atmosphere during explosive events such as solar flares, the chromospheric and coronal heating through the sudden release of magnetic energy remain an open problem in solar physics. Recent hydrodynamic models allow to investigate the energy deposition along a flare loop and to study the response of the chromosphere. These results have been improved with the consideration of transport and acceleration of particles along the loop.RHESSIandFermi/GBM X-ray and gamma-ray observations help to constrain the spectral properties of the injected electrons. The excellent spatial, spectral and temporal resolution ofIRISwill also help us to constrain properties of explosive events, such as the continuum emission during flares or their emission in the chromosphere.
Tidal effects on stellar activity
Authors: Poppenhaeger K. 
Published: September 2017

AbstractThe architecture of many exoplanetary systems is different from the solar system, with exoplanets being in close orbits around their host stars and having orbital periods of only a few days. We can expect interactions between the star and the exoplanet for such systems that are similar to the tidal interactions observed in close stellar binary systems. For the exoplanet, tidal interaction can lead to circularization of its orbit and the synchronization of its rotational and orbital period. For the host star, it has long been speculated if significant angular momentum transfer can take place between the planetary orbit and the stellar rotation. In the case of the Earth-Moon system, such tidal interaction has led to an increasing distance between Earth and Moon. For stars with Hot Jupiters, where the orbital period of the exoplanet is typically shorter than the stellar rotation period, one expects a decreasing semimajor axis for the planet and enhanced stellar rotation, leading to increased stellar activity. Also excess turbulence in the stellar convective zone due to rising and subsiding tidal bulges may change the magnetic activity we observe for the host star. I will review recent observational results on stellar activity and tidal interaction in the presence of close-in exoplanets, and discuss the effects of enhanced stellar activity on the exoplanets in such systems.
Magnetic activity of interacting binaries
Authors: Hill Colin A. 
Published: September 2017

AbstractInteracting binaries provide unique parameter regimes, both rapid rotation and tidal distortion, in which to test stellar dynamo theories and study the resulting magnetic activity. Close binaries such as cataclysmic variables (CVs) have been found to differentially rotate, and so can provide testbeds for tidal dissipation efficiency in stellar convective envelopes, with implications for both CV and planet-star evolution. Furthermore, CVs show evidence of preferential emergence of magnetic flux tubes towards the companion star, as well as large, long-lived prominences that form preferentially within the binary geometry. Moreover, RS CVn binaries also show clear magnetic interactions between the two components in the form of coronal X-ray emission. Here, we review several examples of magnetic interactions in different types of close binaries.
