Social Divisions and International Reconciliation: Domestic Backlash against Foreign Policymaking between Japan and South Korea
Authors: Chun Jahyun 
Published: September 2019

Abstract
The so-called “Comfort Women” Agreement, ratified in December 2015, was intended to bring closure to South Korea's historic grievances against Japan regarding the issue of wartime sexual slavery. However, tensions were reignited when the process and content of the deal were heavily criticized, exacerbating the strained relations between the two countries, as well as divisions within them. Little attention has been given to what happened after the Asian Women's Fund was established in 1995, how bilateral relations shifted, and how the politics changed within South Korea and Japan. This study examines the domestic divisions and conflicts in Japan and South Korea following the introduction of institutions intended to achieve reconciliation. More specifically, it analyzes the factors underlying these divisions and suggests some solutions. In order to do so, this study studies the 1995 Asian Women's Fund and the 2015 “Comfort Women” Agreement, analyzing the implications of these cases in the domestic politics of and bilateral relationship between Japan and South Korea.
Using clinical reasoning ontologies to make smarter clinical decision support systems: a systematic review and data synthesis
Authors: Dissanayake Pavithra I , Colicchio Tiago K , Cimino James J 
Published: September 2019

Abstract

Objective
The study sought to describe the literature describing clinical reasoning ontology (CRO)–based clinical decision support systems (CDSSs) and identify and classify the medical knowledge and reasoning concepts and their properties within these ontologies to guide future research.

Methods
MEDLINE, Scopus, and Google Scholar were searched through January 30, 2019, for studies describing CRO-based CDSSs. Articles that explored the development or application of CROs or terminology were selected. Eligible articles were assessed for quality features of both CDSSs and CROs to determine the current practices. We then compiled concepts and properties used within the articles.

Results
We included 38 CRO-based CDSSs for the analysis. Diversity of the purpose and scope of their ontologies was seen, with a variety of knowledge sources were used for ontology development. We found 126 unique medical knowledge concepts, 38 unique reasoning concepts, and 240 unique properties (137 relationships and 103 attributes). Although there is a great diversity among the terms used across CROs, there is a significant overlap based on their descriptions. Only 5 studies described high quality assessment.

Conclusion
We identified current practices used in CRO development and provided lists of medical knowledge concepts, reasoning concepts, and properties (relationships and attributes) used by CRO-based CDSSs. CRO developers reason that the inclusion of concepts used by clinicians’ during medical decision making has the potential to improve CDSS performance. However, at present, few CROs have been used for CDSSs, and high-quality studies describing CROs are sparse. Further research is required in developing high-quality CDSSs based on CROs.
Structural and functional characterization of a glycoside hydrolase family 3 β-N-acetylglucosaminidase from Paenibacillus sp. str. FPU-7

AbstractChitin, a β-1,4-linked homopolysaccharide of N-acetyl-d-glucosamine (GlcNAc), is one of the most abundant biopolymers on Earth. Paenibacillus sp. str. FPU-7 produces several different chitinases and converts chitin into N,N′-diacetylchitobiose ((GlcNAc)2) in the culture medium. However, the mechanism by which the Paenibacillus species imports (GlcNAc)2 into the cytoplasm and divides it into the monomer GlcNAc remains unclear. The gene encoding Paenibacillus β-N-acetyl-d-glucosaminidase (PsNagA) was identified in the Paenibacillus sp. str. FPU-7 genome using an expression cloning system. The deduced amino acid sequence of PsNagA suggests that the enzyme is a part of the glycoside hydrolase family 3 (GH3). Recombinant PsNagA was successfully overexpressed in Escherichia coli and purified to homogeneity. As assessed by gel permeation chromatography, the enzyme exists as a 57-kDa monomer. PsNagA specifically hydrolyses chitin oligosaccharides, (GlcNAc)2–4, 4-nitrophenyl N-acetyl β-d-glucosamine (pNP-GlcNAc) and pNP-(GlcNAc)2–6, but has no detectable activity against 4-nitrophenyl β-d-glucose, 4-nitrophenyl β-d-galactosamine and colloidal chitin. In this study, we present a 1.9 Å crystal structure of PsNagA bound to GlcNAc. The crystal structure reveals structural features related to substrate recognition and the catalytic mechanism of PsNagA. This is the first study on the structural and functional characterization of a GH3 β-N-acetyl-d-glucosaminidase from Paenibacillus sp.

Published: September 2019

Abstract
Little is known about delirium in elderly burn center patients. The aim of this study is to provide information on the prevalence of delirium and risk factors contributing to the onset of delirium. All patients aged 70 years or older admitted with burn injuries to the Burn Center, Maasstad Hospital, in 2011 to 2017 were eligible for inclusion. We retrospectively collected data regarding the presence of delirium, potential risk factors contributing to the onset of delirium and outcome after delirium. We included elderly 90 patients in this study. The prevalence of delirium in our population was 13% (N = 12). Risk factors for delirium were advanced age, increased American Society for Anesthesiologists score, physical impairment and the use of anticholinergic drugs during admission. Patients with delirium had a poorer outcome, with prolonged hospital stay and increased mortality 6 and 12 months after discharge. Delirium is diagnosed in 13% of the elderly patients admitted to our burn center. Risk factors for delirium found in this study are advanced age, poor physical health status, physical impairment, and the use of anticholinergic drugs. Delirium is related to poor outcomes, including prolonged hospital stay and mortality after discharge.
The Secrecy Effect: Secret Consumption Increases Women’s Product Evaluations and Choice
Authors: Rodas Maria A , John Deborah Roedder 
Published: September 2019

Abstract
Advertisers often depict their products being consumed in a social setting, but they also depict people secretly consuming their products. Will consumers like a product more if they are prompted to consume it in secret? We report eight studies, where women consumed and evaluated products such as cookies, chocolate, and apple chips. Women in secret consumption conditions were instructed to imagine eating the food in secret, instructed to hide the food from others while consuming it, or shown an advertisement encouraging eating the food in secret. These secret consumption prompts resulted in more positive product evaluations and increased product choice, compared to evaluations in non-secret conditions. We identify preoccupation and attitude polarization as the primary drivers for these outcomes. When women consume a product in secret, they become preoccupied with the product, as thoughts about the product continually pop into mind. Increased thinking leads to attitude polarization, where evaluations for products they like become even more positive. Finally, we also identify moderators of these secrecy effects.
The IT Revolution and Southern Europe’s Two Lost Decades
Authors: Schivardi Fabiano , Schmitz Tom 
Published: September 2019

AbstractSince the middle of the 1990s, productivity growth in Southern Europe has been substantially lower than in other developed countries. We argue that this divergence was partly caused by inefficient management practices, which limited Southern Europe’s gains from the IT Revolution. To quantify this effect, we build a multi-country general equilibrium model with heterogeneous firms and workers. In our model, the IT Revolution generates divergence for three reasons. First, inefficient management limits Southern firms’ productivity gains from IT adoption. Second, IT increases the aggregate importance of management, making its inefficiencies more salient. Third, IT-driven wage increases in other countries stimulate Southern high-skill emigration. We calibrate our model using firm-level evidence, and show that it can account for 35% of Italy’s, 47% of Spain’s, and 81% of Portugal’s productivity divergence with respect to Germany between 1995 and 2008. Counterfactual policy experiments show that subsidies to IT adoption or education cannot reduce this gap: only policies that directly tackle inefficient management are effective.
Optimal adjuvant radiotherapy dose for stage I, II or III Merkel cell carcinoma: an analysis of the National Cancer Database
Authors: Yusuf Mehran , Gaskins Jeremy , Wall Weston , Tennant Paul , Bumpous Jeffrey , Dunlap Neal 
Published: September 2019

Abstract

Background
We performed an analysis of the National Cancer Database to determine optimal doses of conventionally-fractionated adjuvant radiotherapy for patients with stage I/II or III Merkel cell carcinoma.

Methods
The cohort included 2735 patients with resected Merkel cell carcinoma of the head and neck, trunk or extremities receiving radiotherapy. Exclusion criteria included doses of radiotherapy <30 or >80 Gy, or dose per fraction >200 or <180 cGy. Recursive partitioning analysis and spline models were used to select dose thresholds. Multivariable Cox regression was performed to validate thresholds with respect to overall survival.

Results
Recursive partitioning analysis models defined a threshold of 57 Gy for stage I/II Merkel cell carcinoma, above which 3-year overall survival rate was decreased (P < 0.0001). The 3-year overall survival rate for patients receiving 50.0–57.0 Gy (81.2%) was greater compared to doses of 30.0–49.9 Gy (75.3%) or >57.0 Gy (70%, P < 0.0001). Doses > 57.0 Gy were associated with an increased hazard of death (1.31, confidence interval 1.07–1.60) with respect to doses of 50.0–57.0 Gy. Doses < 50.0 Gy for stage III Merkel cell carcinoma were associated with worsened 3-year overall survival (P < 0.0001) and increased hazard of death (2.01, confidence interval 1.43–2.82) with respect to doses between 50.0 and 57.0 Gy.

Conclusions
Our results support doses of 50–57 Gy for most patients with stage I/II Merkel cell carcinoma receiving conventionally-fractionated adjuvant radiotherapy. In contrast to a prior National Cancer Database analysis, our results suggest doses ≥ 50 Gy should be strongly considered for patients with stage III Merkel cell carcinoma regardless of anatomic subsite.

Published: September 2019

Abstract

Background
An emerging body of research suggests that noncentral nervous system cancer may negatively impact the brain apart from effects of cancer treatment. However, studies assessing cognitive function in newly diagnosed cancer patients cannot exclude selection bias and psychological effects of cancer diagnosis. To overcome these limitations, we investigated trajectories of cognitive function of patients before cancer diagnosis.

Methods
Between 1989 and 2013, a total of 2059 participants from the population-based Rotterdam Study were diagnosed with noncentral nervous system cancer. Cognitive assessments were performed every 3 to 5 years using a neuropsychological battery. The general cognitive factor was composed of individual cognitive tests to assess global cognition. Using linear mixed models, we compared change in cognitive function of cancer case patients before diagnosis with cognitive change of age-matched cancer-free control subjects (1:2). In addition, we performed sensitivity analyses by discarding assessments of control subjects 5 years before the end of follow-up to exclude effects from potential undiagnosed cancer. All statistical tests were two-sided.

Results
The Word Learning Test immediate recall declined faster among case patients than among control subjects (−0.05, 95% confidence interval = −0.09 to −0.01 vs 0.01, 95% confidence interval = −0.01 to 0.03; P for difference = .003). However, this difference was not statistically significant in sensitivity analyses. Furthermore, no statistically significant differences were observed in change of other individual cognitive tests and of the general cognitive factor.

Conclusions
In this study, we evaluated cognitive function in a large group of cancer patients prior to diagnosis, thereby excluding the psychological impact of cancer diagnosis and biased patient selection. In contrast to previous studies shortly after cancer diagnosis, we found no difference in change of cognitive function between cancer patients and control subjects.
The Doulas of the Priscilla Project: Understanding the Experience of Refugee Women Navigating the US Maternity-care System
Authors: Mendel Whitney E , Sperlich Mickey , Finucane Adair 
Published: September 2019

Abstract
The aim of this qualitative study was to explore pregnant refugee women’s experiences and perceived needs while navigating the US maternity-care system. Using grounded-theory principles, this community-based study was conducted with the doulas of Jericho Road Health Center’s Priscilla Project of Buffalo, which provides pregnant refugee women with culturally and/or linguistically matched doulas and peer mentors in Western New York. Data was sourced from two focus groups and five structured interviews with 13 of the Priscilla Project of Buffalo (PPB) doulas between February and May of 2017. Themes emerged from the data centred on cross-cultural comparisons that contextualize how pregnant refugee women engage with the US maternity-care system, the challenges women face in navigating this and other US systems, and the role of community supports in facilitating navigation. Findings highlight the need for culturally informed and responsive support of refugee women that carry beyond the scope of the delivery room and into the day-to-day navigation of the many systems that influence health and wellbeing.
A complicated abscess from a dropped gallstone
Authors: Murphy Serena , Hebert James , Leavitt Bruce 
Published: September 2019

Abstract
Laparoscopic cholecystectomies represent one of the most common procedures of General Surgery. Dropped gallstones during laparoscopic cholecystectomy is a rare occurrence but can potentially lead to morbid complications. We present a rare case of a broncho-pleuro-cutaneous fistula in a patient with recurrent abscess formations after an elective laparoscopic cholecystectomy. The fistula formed over 3 years from a gallstone that eroded through the diaphragm, into the pleural space, and eventually into a terminal bronchiole. Bilirubin staining within the fistula tract was confirmed on hematoxylin and eosin staining.
Fingerprints and paternity testing: a study of genetics and probability in pre-DNA forensic science
Authors: Asen Daniel 
Published: September 2019

AbstractThis article is a study of forensic science researchers’ attempts to develop paternity tests based on fingerprint patterning, a physical trait that is partially inherited. Pursued in different times and places—ranging from Austria to Japan to China and from the early 20th century to the 1990s—the projects under study represent an ongoing dialogue, carried out through decades of international scientific exchange, about how to extract genetic information from fingerprints and present this data as scientifically-valid evidence in courts of law. Over time, those who engaged in this work increasingly experimented with methods for presenting fingerprint-based evidence of paternity in quantifiable and even probabilistic terms. Fingerprint-based paternity tests remained an obscure area of forensic practice and were eventually overshadowed by advances in serology and DNA profiling. This unfamiliar corner of forensic science, nonetheless, can provide additional perspective on the history of statistical expertise and probabilistic reasoning in modern forensic science, including the application of Bayesian approaches. The larger body of 20th-century ‘dermatoglyphics’ knowledge out of which these tests emerged also continues to influence the foundation of scientific knowledge on which latent print examination is based today.
“Each Unbearable Day”: Narrative Ruthlessness and Environmental and Reproductive Injustice in Jesmyn Ward’s Salvage the Bones
Authors: Bares Annie 
Published: September 2019

AbstractJesmyn Ward’s 2011 novel Salvage the Bones tells the story of Esch Batiste and her family in the days leading up to Hurricane Katrina. Ward represents Esch’s unexpected pregnancy and the environmental degradation of her rural Mississippi Gulf Coast home as linked by the slow, quotidian forms of violence and risk exposure that characterize Jasbir K. Puar’s formulation of debility. Through scenes of reproductive and environmental injustice, Salvage the Bones elucidates the processes through which racially inflected political-economic systems unevenly produce debility in certain populations and environments while capacitating others. When put in conversation with critical race theory, critical disability theory, and environmental criticism, Salvage the Bones emphasizes the logics that underpin debility rather than sensationalizing or pathologizing its consequences. In its refusal to revert to ableist, racist literary codes and conventions, the novel theorizes and practices “narrative ruthlessness,” Ward's description of her literary strategy to respond to debility’s representational conundrums of inevitability and invisibility. In so doing, narrative ruthlessness exceeds liberal humanist impulses to propose restoration, cure, or uplift as desirable solutions, insisting instead on kinship, care, redress, and salvage as possibilities for radical survival and futurity.
The connection between halo concentrations and assembly histories: a probe of gravity?
Authors: Oleśkiewicz Piotr , Baugh Carlton M , Ludlow Aaron D 
Published: September 2019

ABSTRACT
We use two high-resolution N-body simulations, one assuming general relativity (GR) and the other the Hu–Sawicki form of f(R) gravity with $\vert \bar{f}_{\mathrm{ R}} \vert = 10^{-6}$, to investigate the concentration–formation time relation of dark matter haloes. We assign haloes to logarithmically spaced mass bins, and fit median density profiles and extract median formation times in each bin. At fixed mass, haloes in modified gravity are more concentrated than those in GR, especially at low masses and low redshift, and do not follow the concentration–formation time relation seen in GR. We assess the sensitivity of the relation to how concentration and formation time are defined, as well as to the segregation of the halo population by the amount of gravitational screening. We find a clear difference between halo concentrations and assembly histories displayed in modified gravity and those in GR. Existing models for the mass–concentration–redshift relation that have gained success in cold and warm dark matter models require revision in f(R) gravity.
Kinetic theory of the electron strahl in the solar wind
Authors: Boldyrev Stanislav , Horaites Konstantinos 
Published: September 2019

ABSTRACT
We develop a kinetic theory for the electron strahl, a beam of energetic electrons which propagate from the sun along the Parker-spiral-shaped magnetic field lines. Assuming a Maxwellian electron distribution function in the near-sun region where the plasma is collisional, we derive the strahl distribution function at larger heliospheric distances. We consider the two most important mechanisms that broaden the strahl: Coulomb collisions and interactions with oblique ambient whistler turbulence (anomalous diffusion). We propose that the energy regimes where these mechanisms are important are separated by an approximate threshold, ${\cal E}_\mathrm{ c}$; for the electron kinetic energies ${\cal E}\,\lt\, {\cal E}_\mathrm{ c}$ the strahl width is mostly governed by Coulomb collisions, while for ${\cal E}\,\gt\, {\cal E}_\mathrm{ c}$ by interactions with the whistlers. The Coulomb broadening decreases as the electron energy increases; the whistler-dominated broadening, on the contrary, increases with energy and it can lead to efficient isotropization of energetic electrons and to the formation of the electron halo. The threshold energy ${\cal E}_\mathrm{ c}$ is relatively high in the regions closer to the sun, and it gradually decreases with the distance, implying that the anomalous diffusion becomes progressively more important at large heliospheric distances. At 1 au, we estimate the energy threshold to be about ${\cal E}_\mathrm{ c}\,\sim\, 200\, {\rm eV}$.
The Milky Way bar/bulge in proper motions: a 3D view from VIRAC and Gaia

Published: September 2019

Abstract
We have derived absolute proper motions of the entire Galactic bulge region from VVV Infrared Astrometric Catalogue (VIRAC) and Gaia. We present these both as integrated on-sky maps and, after isolating standard candle red clump (RC) stars, as a function of distance using RC magnitude as a proxy. These data provide a new global, 3D view of the Milky Way barred bulge kinematics. We find a gradient in the mean longitudinal proper motion, $\langle \mu _ l^\star \rangle $, between the different sides of the bar, which is sensitive to the bar pattern speed. The split RC has distinct proper motions and is colder than other stars at similar distance. The proper motion correlation map has a quadrupole pattern in all magnitude slices showing no evidence for a separate, more axisymmetric inner bulge component. The line-of-sight integrated kinematic maps show a high central velocity dispersion surrounded by a more asymmetric dispersion profile. $\sigma _{\mu _l} / \sigma _{\mu _b}$ is smallest, ≈1.1, near the minor axis and reaches ≈1.4 near the disc plane. The integrated $\langle \mu_b\rangle$ pattern signals a superposition of bar rotation and internal streaming motion, with the near part shrinking in latitude and the far part expanding. To understand and interpret these remarkable data, we compare to a made-to-measure barred dynamical model, folding in the VIRAC selection function to construct mock maps. We find that our model of the barred bulge, with a pattern speed of 37.5 $\mathrm{ \mathrm{ km \, s^{-1}} \, kpc^{-1} }$, is able to reproduce all observed features impressively well. Dynamical models like this will be key to unlocking the full potential of these data.
