AT HOME AND ABROAD: Reflections on Collaborative Museum Ethnography at the Mathers Museum of World Cultures
Authors: Jackson Jason Baird 
Published: September 2019

AbstractIn a reflective essay, the author draws upon experiences in two ongoing projects to suggest ways in which the literatures on museum‐based ethnographic collaboration might be enriched and extended. One illustrative project is a binational, multi‐institutional endeavor linking six museums within a larger program of cooperation led by two national scholarly societies. The other case is the work of an ethnographically oriented, museum‐based public arts program working on a statewide basis in a midwestern state in the United States. The author concludes with a call to develop frameworks for fostering partnership activities between museums of ethnography.

AbstractBackgroundThe burden of out‐of‐hospital cardiac arrest (OHCA) on different population segments in developing countries is not well studied. Previous studies from Lebanon report poor survival to hospital discharge (4.8%‐5.5%). This study describes characteristics and outcomes of young OHCA victims in Beirut, LebanonMethodsThis retrospective observational study included young patients (<35 years of age) with OHCA admitted to the emergency department (ED) of a tertiary care center in Lebanon over a 10‐year period.ResultsFifty‐four patients with OHCA were identified. Most were males (74.1%, n = 40) and the mean age was 17.9 ± 10.9 years. The most common arrest location was home (44.4%, n = 24). The majority were witnessed (78.8%, n = 41) with 15.4% (n = 8) witnessed by emergency medical services (EMS). Prehospital cardiopulmonary resuscitation was done for 22 patients (41.5%) mostly by EMS (n = 19, 86.4%), 9.1% (n = 2) by a bystander, and 4.5% (n = 1) by a family member. Prehospital automated external defibrillator use was documented in 13% (n = 7) of cases. Most patients (n = 48, 88.9%) were resuscitated in the ED where the most common rhythm was asystole (55.6%, n = 30). Half of the patients (50%, n = 27) survived to hospital admission. Overall survival to hospital discharge was 16.7% (n = 9). Good neurologic outcome (cerebral performance category 1 or 2) was documented in seven patients (9.3%).ConclusionSurvival rate of young OHCA victims in Lebanon (16.7%) is higher than previously reported rates of OHCA in the overall population. Targeted community activities and medical oversight of EMS activities are needed to link EMS activities to clinical outcomes.

Authors: Gabes Michaela , Tischer Christina , Apfelbacher Christian ,   for the quality of life working group of the Harmonising Outcome Measures for Eczema (HOME) initiative
Published: September 2019

AbstractObjectiveThe aim of this updated systematic review was to systematically assess the measurement properties of previously discussed and new quality‐of‐life patient‐reported outcome measures (PROMs) in children and adults with eczema using the new COSMIN guideline.MethodsA systematic literature search was conducted in PubMed and EMBASE. Eligible studies reported on measurement properties of quality‐of‐life PROMs for children and adults with eczema. The methodological quality of selected already known PROMs and new evidence identified through the literature search was assessed with the COSMIN Risk of Bias checklist. The adequacy of included PROMs was judged with updated quality criteria, and the quality of evidence of the summarized results was graded. Finally, PROMs were placed in a recommendation category (A‐C).ResultsIn total, 133 measurement properties of nine different PROMs were assessed. No PROM could be placed in category A due to a lack of validation studies. Only the DLQI fulfilled the criteria for category C and therefore should not be recommended for use. All other PROMs were placed in category B, that is, they still have the opportunity to be recommended, but need further validation.ConclusionsCurrently, no PROM for quality of life can be recommended for use in children and adults with eczema. Further validation is needed. The DLQI cannot be recommended for future use.

AbstractThe fascia is an undifferentiated mesenchymal tissue related to the peripheral nerves. Both can be identified by ultrasound, which is useful when performing peripheral nerve blocks. However, there is no unanimity about the approaching point of each nerve, nor is there a consensus on how to name the appropriate infiltration zone, although the paraneural zone is frequently mentioned. The aims of this study were to determine if ultrasound is accurate for identifying the fascial planes and the paraneural space of the nerves in the knee, infiltrating them, and achieving a correct anatomical diffusion, as well as for establishing access routes to avoid intraneural infiltration. The study was performed in 16 cryopreserved lower extremities of the dissection room of the Faculty of Medicine and Health Sciences, University of Barcelona. Nerves of the knee were injected with colorant guided by ultrasound after they were visualized. Correct location of the nerves by ultrasound was achieved in 98.75% of the cases, correct visualization of the needle by ultrasound in 82.5%, the hypoechogenic image around the nerve after infiltration in 82.5%, and a correct paraneural infiltration in 76.25% of cases. With these results, we can conclude that high‐definition ultrasound enables location of the peripheral nerves and adjacent structures as well as the fasciae that surround them, and therefore allows performance of infiltrations in the paraneural spaces.

AimGlial fibrillary acidic protein (GFAP), the intermediate filament protein expressed in astrocytes, plays a key role in many aspects of brain function through communication with neurons or blood vessels. A common single nucleotide polymorphism (SNP), GFAP –250 C/A (rs2070935), is associated with the transcriptional regulation of GFAP, which can potentially result in the genotype‐specific brain structure. This study aimed to verify the biological effects of the GFAP variants on brain structure and function.MethodsWe investigated the associations between the GFAP variants and magnetic resonance imaging findings, including gray and white matter volumes, white matter integrity, and resting arterial blood flow, from 1212 healthy Japanese subjects.ResultsThe GFAP –250 C/A genotype was significantly associated with total gray matter volume, total white matter volume, average mean diffusivity, and mean cerebral blood flow. In voxel‐by‐voxel analyses, the GFAP genotype showed significant associations with the regional gray and white matter volumes in the inferior frontal lobe and corpus callosum, the regional mean diffusivity in the left posterior region, and the regional cerebral blood flow throughout the brain.ConclusionThis study revealed a common SNP that is significantly associated with multiple global brain structure parameters.
An empirical analysis on the effects of the inflation targeting framework on monetary policy in South Africa
Authors: Chen Weiming , Creamer Kenneth 
Published: September 2019

AbstractThis article examines the impact of the adoption of an Inflation Targeting (IT) framework in 2000 on the conduct of South Africa’s monetary policy. Taylor rule analysis is used to test empirically whether the implementation of IT in South Africa can be shown to have impacted on the conduct of monetary policy. In particular, the article analyses whether the implementation of the IT framework yields the expected changes when comparing the conduct of monetary policy pre and post the adoption of the IT framework. Thereafter, an analysis of term structure of interest rates, which serve as a proxy variable for market expectations, is used to test whether South Africa’s IT framework has resulted in more predictability and transparency in monetary policy conduct. Lastly, the article analyses the impact of the global financial crisis of 2008–2009, the so‐called Great Recession, on the predictability and transparency of monetary policy in South Africa.
Bank Income Diversification, Asset Correlation and Systemic Risk
Authors: Lee Chien‐Chiang , Chen Pei‐Fen , Zeng Jhih‐Hong 
Published: September 2019

AbstractThis paper explores whether the asset correlations among the non‐interest activities of banks are the key causes for enhancing the bank diversification‐systemic risk nexus. Our empirical evidence indicates that banks' income diversification significantly raises systemic risk. After removing those banks with high asset correlations, the effect of individual banks' diversification on banking systemic risk turns insignificant or even inverse. The results show that high asset correlations among banks could introduce bank failures, thereby leading to higher systemic risk in the financial sector.
Proximal Correlates of Suicidal Ideation and Behaviors: A Test of the Interpersonal‐Psychological Theory of Suicide

Published: September 2019

ObjectiveThe interpersonal‐psychological theory of suicide hypothesizes proximal causes of suicidal ideation and behaviors; however, past studies have generally tested distal relations. The present study tested the proximal nature of the theory’s hypotheses.MethodsA repeated‐measures design collected daily survey data on the theory constructs over 90 days from 206 (150 women) college students with previous histories of suicidal ideation. Participants completed 7,342 (39.6%) of the 18,540 surveys sent.ResultsThwarted belongingness and perceived burdensomeness both positively associated with passive suicidal ideation at the daily level. A statistical trend revealed that perceived burdensomeness was associated with daily active suicidal ideation only at high levels of thwarted belongingness and hopelessness. Active suicidal ideation, but not capability for suicide, was positively associated with suicidal behavior at the daily level.ConclusionsThese results support the theory’s predictions regarding passive and active suicidal ideation, with limited support regarding suicidal behaviors. The proximal associations of the IPTS constructs with daily suicidal ideation suggest areas for potential intervention with suicidal clients.
Multifidelity and Multiscale Bayesian Framework for High-Dimensional Engineering Design and Calibration

Published: September 2019

AbstractThis paper proposes a machine learning–based multifidelity modeling (MFM) and information-theoretic Bayesian optimization approach where the associated models can have complex discrepancies among each other. Advantages of MFM-based optimization over a single-fidelity surrogate, specifically under complex constraints, are discussed with benchmark optimization problems involving noisy data. The MFM framework, based on modeling of the varied fidelity information sources via Gaussian processes, is augmented with information-theoretic active learning strategies that involve sequential selection of optimal points in a multiscale architecture. This framework is demonstrated to exhibit improved efficiency on practical engineering problems like high-dimensional design optimization of compressor rotor via implementing its multiscale architecture and calibration of expensive microstructure prediction model. From the perspective of the machine learning–assisted design of multiphysics systems, advantages of the proposed framework have been presented with respect to accelerating the search of optimal design conditions under budget constraints.
Properties and Corrosion Resistance of Borided AISI H11 Tool Steel
Authors: Günen Ali 
Published: September 2019

Abstract
In this study, the effect of different boriding parameters on some mechanical properties and corrosion resistance of AISI H11 steel, which is extensively used in hot and cold processing applications, was investigated. The grown boride layers were compact and crack-free for all boriding conditions, and they were detected as single phase (Fe2B) at 800 °C and dual phase (FeB + Fe2B) at 900 and 1000 °C. Depending on the treatment condition, the thickness, surface hardness, and Ra values of the coatings were ranged 10.25–94.5 µm, 1704–2015 HV, and 0.285–0.650 µm, respectively. The corrosion resistance was observed to be related to the phase structure, coating thickness, surface roughness, and the density of the boride layers. There is found to be an increase in the corrosion resistance up to almost 65 times after the boriding process, due to the barrier effect of the grown boride layers (such as B2O3).
Non-Synchronous Aeroacoustic Interaction in an Axial Multi-Stage Compressor

Published: September 2019

Abstract
Non-engine order rotor blade vibration is an aeroelastic phenomenon of major interest for compressor designers resulting from excitation of rotor blade modes through aerodynamic instabilities. Indicators for a comparable type of instability, caused by propagating acoustic modes, have been observed in an experimental multistage high-speed compressor by Safran Helicopter Engines. It is intended to understand the cause of these instabilities by combining experimental data and numerical simulations. Unsteady pressure measurements were carried out by case-mounted and stator-mounted transducers. Rotor tip-timing and magnet-coil sensor systems were installed to measure the blade vibrations. Experimental results show non-engine order signatures in the unsteady pressure signal coherent to the shifted frequency of blade vibrations. In the present paper, the waveform of these oscillations is analyzed in detail, showing a dominant propagating acoustic mode interacting with vibrations of rotor 2. The root cause for the non-synchronous oscillations is identified as an acoustic mode that is cutoff downstream of rotor 3. During the test, the mode changes its frequency and circumferential order, affecting the amplitude of associated blade vibrations.

Background: To examine relations between parents’ perceived neighborhood recreation environments and multiple measures of adolescent physical activity (PA). Methods: Participants (N = 928; age 14.1 [1.4] y, 50.4% girls, and 33.4% nonwhite/Hispanic) and their parents were recruited. Teen moderate to vigorous PA (MVPA) was assessed with 7-day accelerometry. Self-reported total PA, PA near home, and PA at recreation locations were also assessed. Proximity of home to 8 types of recreation facilities was reported by parents. Mixed-model linear regressions relating environments to various measures of PA were adjusted for demographics and neighborhood clustering. Results: Perceiving more availability of recreation facilities around home was related to higher reports of days per week with 60+ minutes of PA (b = 0.153; P < .05), reported PA time near home (b = 0.152; P < .001), PA time at recreation facilities (b = 0.161; P < .001), accelerometer-measured total MVPA (b = 1.741; P < .05), and nonschool MVPA (b = 1.508; P < .01). Adolescents living in lowest quintile of recreation facility availability averaged 27.6 (3.2) minutes per day of total MVPA versus 49.8 (3.5) minutes per day for those living in highest quintile. Conclusions: Adolescents living in neighborhoods that parents reported having more availability of recreation facilities around homes had higher activity across 5 indicators of PA.
Intramural Ice Hockey: Are you Covered?
Authors: Adler Phillip , Shingles René Revis 
Published: September 2019

The following article outlines the important steps taken to develop a Standard Operating Procedure for handling injuries during intramural ice hockey at an ice arena. The existing SOP for handling injuries did not include ice hockey and needed to be modified in order to facilitate the circumstances of a new ice rink, a new intramural sport, and an inexperienced staff. When no published guidelines were found while these new procedures were being developed, we created our own which we are sharing. The SOP development was separated into stages: researching the rules of the sport and the injuries that might occur; examining the facility for emergency exists and determining staffing and responsibilities; the classification of injuries and how to reach and remove the injured athlete; and, staff education, game day responsibilities, and the evaluation of the SOP was performed.
RSFit3000: A MATLAB GUI-based program for determining rate and state frictional parameters from experimental data
Authors: Skarbek Rob M. , Savage Heather M. 
Published: September 2019

AbstractWe present a MATLAB graphical user interface (GUI) software package for analyzing rate and state friction experiments. Called RSFit3000, the software allows users to easily determine frictional parameters by fitting velocity-step and slide-hold-slide events using the aging- and slip-law forms for state variable evolution. RSFit3000 includes features for removing strain hardening or weakening trends from the data, and provides options for using two state variables, applying a weighting function, and treating stiffness as a fitting parameter. Completed fits are conveniently saved in MATLAB structure arrays that contain fitted parameter values with their error intervals, and all information required to reproduce a given fit. The GUI makes the program simple to use, as all fitting tasks are completed via interaction with the interface. Here we describe how to use the software, and illustrate its flexibility and utility by analyzing two sets of synthetic friction data, as well as some previously published experimental data. Although descriptions of rate and state friction fitting routines have been published in the past, RSFit3000 marks the first time a software package for analyzing friction experiments has been described in the literature.

Abstract

Objective
To evaluate the effectiveness and success of uterus preserving sacrospinous hysteropexy as an alternative to vaginal hysterectomy with uterosacral ligament suspension in the surgical treatment of uterine prolapse five years after surgery.

Design
Observational follow-up of SAVE U (sacrospinous fixation versus vaginal hysterectomy in treatment of uterine prolapse ≥2) randomised controlled trial.

Setting
Four non-university teaching hospitals, the Netherlands.

Participants
204 of 208 healthy women in the initial trial (2009-12) with uterine prolapse stage 2 or higher requiring surgery and no history of pelvic floor surgery who had been randomised to sacrospinous hysteropexy or vaginal hysterectomy with uterosacral ligament suspension. The women were followed annually for five years after surgery. This extended trial reports the results at five years.

Main outcome measures
Prespecified primary outcome evaluated at five year follow-up was recurrent prolapse of the uterus or vaginal vault (apical compartment) stage 2 or higher evaluated by pelvic organ prolapse quantification system in combination with bothersome bulge symptoms or repeat surgery for recurrent apical prolapse. Secondary outcomes were overall anatomical failure (recurrent prolapse stage 2 or higher in apical, anterior, or posterior compartment), composite outcome of success (defined as no prolapse beyond the hymen, no bothersome bulge symptoms, and no repeat surgery or pessary use for recurrent prolapse), functional outcome, quality of life, repeat surgery, and sexual functioning.

Results

At five years, surgical failure of the apical compartment with bothersome bulge symptoms or repeat surgery occurred in one woman (1%) after sacrospinous hysteropexy compared with eight women (7.8%) after vaginal hysterectomy with uterosacral ligament suspension (difference−6.7%, 95% confidence interval −12.8% to−0.7%). A statistically significant difference was found in composite outcome of success between sacrospinous hysteropexy and vaginal hysterectomy (89/102 (87%)
v
77/102 (76%). The other secondary outcomes did not differ. Time-to-event analysis at five years showed no differences between the interventions.

Conclusions
At five year follow-up significantly less anatomical recurrences of the apical compartment with bothersome bulge symptoms or repeat surgery were found after sacrospinous hysteropexy compared with vaginal hysterectomy with uterosacral ligament suspension. After hysteropexy a higher proportion of women had a composite outcome of success. Time-to-event analysis showed no differences in outcomes between the procedures.

Seesaw mechanism and pseudo C-symmetry
Authors: Fujikawa Kazuo , Tureanu Anca 
Published: September 2019

Abstract
It is shown that the specific “charge conjugation” transformation used to define the Majorana fermions in the conventional seesaw mechanism, namely $$(\nu _{R})^{C}=C\overline{\nu _{R}}^{T}$$(νR)C=CνR¯T for a chiral fermion $$\nu _{R}$$νR (and similarly for $$\nu _{L}$$νL), is a hidden symmetry associated with CP symmetry, and thus it formally holds independently of the P- and C-violating terms in the CP invariant Lagrangian and it is in principle applicable to charged leptons and quarks as well. This hidden symmetry, however, is not supported by a consistent unitary operator and thus it leads to mathematical (operatorial) ambiguities. When carefully examined, it also fails as a classical transformation law in a Lorentz invariant field theory. To distinguish it from the standard charge conjugation symmetry, we suggest for it the name of pseudo C-symmetry. The pseudo C-symmetry is effective to identify Majorana neutrinos analogously to the classical Majorana condition. The analysis of CP breaking in weak interactions is performed using the conventional CP transformation, which is defined independently of the pseudo C-transformation, in the seesaw model after mass diagonalization. A way to ensure an operatorially consistent formulation of C-conjugation is to formulate the seesaw scheme by invoking a relativistic analogue of the Bogoliubov transformation.
