Published: May 2018

This work reports on the fundamental properties of nanostructured catalysts active in the main carbon oxides’ conversion processes for sustainable energy supply: methanation and co-methanation of CO2. Transition metals (e.g. Ni, Pd, Pt, Co, Ru, Rh) are active species in both reactions. Ni has been the most studied because of its cheapness. Monometallic and bi-metallic Ni and Ni3Fe catalysts supported on Gadolinia-doped ceria (GDC) have been synthesized, characterized and tested in the temperature range 200–600[Formula: see text]C. In the methanation reaction, the monometallic catalyst showed higher performance with respect to the bi-metallic catalyst. At 400[Formula: see text]C, the CO2 conversion overcomes 90% with CH4 selectivity of 100%. In co-methanation, the highest CO2, CO and H2 conversion values over monometallic Ni/GDC catalyst were obtained at 300[Formula: see text]C; at higher temperatures, conversion decreases. The GDC support plays a pivotal role in both reactions, enhancing the basicity of the catalyst and improving the dissociation of carbon oxide species adsorbed on Ni sites.

Published: May 2018

In order to study the dynamic and fracture behavior of 6005 aluminum alloy at different strain rates and stress states, various tests (tensile tests at different strain rates and tensile shearing tests at five stress states) are conducted by Mechanical Testing and Simulation (MTS) and split‐Hopkinson tension bar (SHTB). Numerical simulations based on the finite element method (FEM) are performed with ABAQUS/Standard to obtain the actual stress triaxialities and equivalent plastic strain to fracture. The results of tensile tests for 6005 Al show obvious rate dependence on strain rates. The results obtained from simulations indicate the feature of nonmonotonicity between the strain to fracture and stress triaxiality. The equivalent plastic strain reduces to a minimum value and then increases in the stress triaxiality range from 0.04 to 0.30. A simplified Johnson‐Cook (JC) constitutive model is proposed to depict the relationship between the flow stress and strain rate. What is more, the strain‐rate factor is modified using a quadratic polynomial regression model, in which it is considered to vary with the strain and strain rates. A fracture criterion is also proposed in a low stress triaxiality range from 0.04 to 0.369. Error analysis for the modified JC model indicates that the model exhibits higher accuracy than the original one in predicting the flow stress at different strain rates. The fractography analysis indicates that the material has a typical ductile fracture mechanism including the shear fracture under pure shear and the dimple fracture under uniaxial tensile.

The removal of pollutants from textile wastewater via electrochemical oxidation and a coupled system electrooxidation—Salix babylonica, using boron-doped diamond electrodes was evaluated. Under optimal conditions of pH 5.23 and 3.5 mA·cm−2 of current density, the electrochemical method yields an effective reduction of chemical oxygen demand by 41.95%, biochemical oxygen demand by 83.33%, color by 60.83%, and turbidity by 26.53% at 300 minutes of treatment. The raw and treated wastewater was characterized by infrared spectroscopy to confirm the degradation of pollutants. The wastewater was oxidized at 15-minute intervals for one hour and was placed in contact with willow plants for 15 days. The coupled system yielded a reduction of the chemical oxygen demand by 14%, color by 85%, and turbidity by 93%. The best efficiency for the coupled system was achieved at 60 minutes, at which time the plants achieved more biomass and photosynthetic pigments.
A Method for Fast Leaderboard Calculations in Massive Online Game-Based Environments
Authors: Moreno Cadavid Julian , Vanegas Madrigal Hernán Darío
Published: May 2018

Leaderboards and other game elements are present in many online environments, not just in videogames. When such environments have relatively few users, the implementation of those leaderboards is not usually a problem; however, that is no longer the case when they have dozens of thousands or more. For those situations we propose a method that is easy and cheap to implement. It is based on two particular data structures, a Self-Balanced Ordering Statistic Tree and a hash table, to perform proper leaderboard calculations in a fast and cheap way. More specifically, our proposal has O(log2⁡N) time complexity, whereas other approaches also based on in-memory data structures like linked lists have O(N), and others based on Hard Disk Drive operations like a relational database have O(Nlog2⁡N). Such improvement with regard to the other approaches is corroborated with experimental results for several scenarios, also presented in this paper.

Published: May 2018

A model-based radiostereometric analysis (MBRSA) is a method for precise measurement of prosthesis migration, which does not require marking the implant with tantalum beads. Instead, the prosthesis pose is typically recovered using a feature-based 2D-3D registration of its virtual model into a stereo pair of radiographs. In this study, we evaluate a novel intensity-based formulation of previously published nonoverlapping area (NOA) approach. The registration is capable of performing with both binary radiographic segmentations and nonsegmented X-ray images. In contrast with the feature-based version, it is capable of dealing with unreliable parts of prosthesis. As the straightforward formulation allows efficient acceleration using modern graphics adapters, it is possible to involve precise high-poly virtual models. Moreover, in case of binary segmentations, the nonoverlapping area is simply interpretable and useful for indicating the accuracy of the registration outcome. In silico and phantom evaluations were performed using a cementless Zweymüller femoral stem and its reverse engineered (RE) model. For initial pose estimates with difference from the ground-truth limited to ±4 mm and ±4°, respectively, the mean absolute translational error was not higher than 0.042 ± 0.035 mm. The error in rotation around the proximodistal axis was 0.181 ± 0.265°, and the error for the remaining axes was not higher than 0.035 ± 0.037°.
Numerical Study of a Southwest Vortex Rainstorm Process Influenced by the Eastward Movement of Tibetan Plateau Vortex
Authors: Liu Xiaoli , Ma Endian , Cao Zhibin , Jin Shuanglong
Published: May 2018

A number of studies revealed the possible eastward movement of the Tibetan Plateau low-pressure system in summer and indicated the enhancement effect of this process on the southwest vortex in the Sichuan Basin, which can induce strong convective precipitation and flood events in China. In this study, a numerical simulation of a southwest vortex rainstorm process was performed. The results show that the low-pressure system originated from the Tibetan Plateau affects the southwest vortex mainly at the middle level, causing the strength increase of southwest vortex (SWV), and acts as a connection between the positive vorticity centers at the upper and lower layers. For the microscopic cloud structure, the vertical updraft of the cloud cluster embedded in the SWV increases as the low-pressure system from the plateau arrives at the Sichuan Basin. Vapor and liquid cloud water at the lower level are transported upward, based on which the ice cloud at the upper level and the warm cloud at the lower level are joined to create favorable conditions for the growth of ice crystals. As the ice crystals grow up, snow and graupel particles form, which substantially elevates the precipitation. This effect leads to the rapid development of SWV rainstorm clouds and the occurrence of precipitation. In addition to the effect of the plateau vortex, the subsequent merging of the convective clouds is another important factor for heavy rainfall because it also leads to development of convective clouds, causing heavy rainfall.
A Classification Detection Algorithm Based on Joint Entropy Vector against Application-Layer DDoS Attack
Authors: Zhao Yuntao , Zhang Wenbo , Feng Yongxin , Yu Bo
Published: May 2018

The application-layer distributed denial of service (AL-DDoS) attack makes a great threat against cyberspace security. The attack detection is an important part of the security protection, which provides effective support for defense system through the rapid and accurate identification of attacks. According to the attacker’s different URL of the Web service, the AL-DDoS attack is divided into three categories, including a random URL attack and a fixed and a traverse one. In order to realize identification of attacks, a mapping matrix of the joint entropy vector is constructed. By defining and computing the value of EUPI and jEIPU, a visual coordinate discrimination diagram of entropy vector is proposed, which also realizes data dimension reduction from N to two. In terms of boundary discrimination and the region where the entropy vectors fall in, the class of AL-DDoS attack can be distinguished. Through the study of training data set and classification, the results show that the novel algorithm can effectively distinguish the web server DDoS attack from normal burst traffic.

Loss of the short arm of chromosome 3 (3p) occurs early in >95% of clear cell renal cell carcinoma (ccRCC). Nearly ubiquitous 3p loss in ccRCC suggests haploinsufficiency for 3p tumor suppressors as early drivers of tumorigenesis. We previously reported methyltransferase SETD2, which trimethylates H3 histones on lysine 36 (H3K36me3) and is located in the 3p deletion, to also trimethylate microtubules on lysine 40 (αTubK40me3) during mitosis, with αTubK40me3 required for genomic stability. We now show that monoallelic, Setd2-deficient cells retaining H3K36me3, but not αTubK40me3, exhibit a dramatic increase in mitotic defects and micronuclei count, with increased viability compared with biallelic loss. In SETD2-inactivated human kidney cells, rescue with a pathogenic SETD2 mutant deficient for microtubule (αTubK40me3), but not histone (H3K36me3) methylation, replicated this phenotype. Genomic instability (micronuclei) was also a hallmark of patient-derived cells from ccRCC. These data show that the SETD2 tumor suppressor displays a haploinsufficiency phenotype disproportionately impacting microtubule methylation and serves as an early driver of genomic instability.

Significance: Loss of a single allele of a chromatin modifier plays a role in promoting oncogenesis, underscoring the growing relevance of tumor suppressor haploinsufficiency in tumorigenesis. Cancer Res; 78(12); 3135–46. ©2018 AACR.
USP11 Enhances TGFβ-Induced Epithelial–Mesenchymal Plasticity and Human Breast Cancer Metastasis

Published: May 2018

Epithelial–mesenchymal transition (EMT) is a conserved cellular plasticity program that is reactivated in carcinoma cells and drives metastasis. Although EMT is well studied its regulatory mechanisms remain unclear. Therefore, to identify novel regulators of EMT, a data mining approach was taken using published microarray data and a group of deubiquitinases (DUB) were found to be upregulated in cells that have undergone EMT. Here, it is demonstrated that one DUB, ubiquitin-specific peptidase 11 (USP11), enhances TGFβ-induced EMT and self-renewal in immortalized human mammary epithelial cells. Furthermore, modulating USP11 expression in human breast cancer cells altered the migratory capacity in vitro and metastasis in vivo. Moreover, elevated USP11 expression in human breast cancer patient clinical specimens correlated with decreased survival. Mechanistically, modulating USP11 expression altered the stability of TGFβ receptor type II (TGFBR2) and TGFβ downstream signaling in human breast cancer cells. Together, these data suggest that deubiquitination of TGFBR2 by USP11 effectively spares TGFBR2 from proteasomal degradation to promote EMT and metastasis.

Implications: USP11 regulates TGFβ-induced epithelial–mesenchymal plasticity and human breast cancer metastasis and may be a potential therapeutic target for breast cancer. Mol Cancer Res; 16(7); 1172–84. ©2018 AACR.

AHNAK is known to be a tumor suppressor in breast cancer due to its ability to activate the TGFβ signaling pathway. However, the role of AHNAK in lung tumor development and progression remains unknown. Here, the Ahnak gene was disrupted to determine its effect on lung tumorigenesis and the mechanism by which it triggers lung tumor development was investigated. First, AHNAK protein expression was determined to be decreased in human lung adenocarcinomas compared with matched nonneoplastic lung tissues. Then, Ahnak−/− mice were used to investigate the role of AHNAK in pulmonary tumorigenesis. Ahnak−/− mice showed increased lung volume and thicker alveolar walls with type II pneumocyte hyperplasia. Most importantly, approximately 20% of aged Ahnak−/− mice developed lung tumors, and Ahnak−/− mice were more susceptible to urethane-induced pulmonary carcinogenesis than wild-type mice. Mechanistically, Ahnak deficiency promotes the cell growth of lung epithelial cells by suppressing the TGFβ signaling pathway. In addition, increased numbers of M2-like alveolar macrophages (AM) were observed in Ahnak−/− lungs, and the depletion of AMs in Ahnak−/− lungs alleviated lung hyperplastic lesions, suggesting that M2-like AMs promoted the progression of lung hyperplastic lesions in Ahnak-null mice. Collectively, AHNAK suppresses type II pneumocyte proliferation and inhibits tumor-promoting M2 alternative activation of macrophages in mouse lung tissue. These results suggest that AHNAK functions as a novel tumor suppressor in lung cancer.

Implications: The tumor suppressor function of AHNAK, in murine lungs, occurs by suppressing alveolar epithelial cell proliferation and modulating lung microenvironment. Mol Cancer Res; 16(8); 1287–98. ©2018 AACR.

Published: May 2018

Background:

Coronary artery fluid dynamics may be altered because of the nonphysiological flow seen in continuous-flow left ventricular assist devices (CF-LVADs). Our aim was to study the structure and composition of coronary vessels after CF-LVAD.

Methods and Results:

Coronary arteries were collected from patients with heart failure (HF) at the time of transplantation, of whom 15 were supported with a CF-LVAD before transplant (HF+LVAD group) and 9 were not (HF non-LVAD group). In addition, coronary samples were obtained from 5 nonfailing age-matched donors (nonfailing group). Histological analysis was performed to quantify coronary morphology, composition, vascular fibrosis, and vasa vasorum density. The age and sex mix of the 3 groups were similar, and the mean duration of LVAD support was 213 days. Compared with patients with HF and nonfailing donors, the arteries from patients with HF+LVAD had expansion of the adventitia, breakdown of the internal elastic lamina, and increased adventitial collagen deposition and density of vasa vasorum.

Conclusions:

Among patients supported with CF-LVADs, the coronary arteries develop marked remodeling with increased adventitial fibrosis. The physiological consequences of these structural changes are unknown, but it is possible that arterial contractility may be impaired, thus limiting coronary flow reserve and promoting myocardial ischemia. This may contribute to CF-LVAD complications, such as ventricular arrhythmias and right ventricular failure. As more patients receive CF-LVADs and new pump technology attempts to modulate flow profiles and pulsatility, further research is needed to understand the mechanisms and long-term sequela of these changes in coronary arteries and other vascular beds.
Sociolinguistic Indexicalities in Ethnic Diversity
Authors: Stell Gerald
Published: May 2018

Ethnicity and language have often been considered jointly on the grounds of their intrinsic interrelation: hard ethnic boundaries are manifested by the use of heritage languages, while dynamics of assimilation reduce the need to linguistically project ethnic distinctness. This article seeks to test the interrelation between patterns of language use and ethnic boundaries in the context of Suriname by analyzing perceptions of ethnolinguistic boundaries elicited from a sample of young informants from Paramaribo. The findings suggest that Surinamese ethnic boundaries are salient, albeit eroding in urban areas. Erosion is visible at a linguistic level in what seems to be a general shift in urban areas toward Dutch and Sranan Tongo. However, this shift might be proceeding at different paces from one ethnic group to the next. As a result, ethnicity is reflected in variable levels of linguistic competence in Dutch and Sranan Tongo.

On the Characteristics of Linear-Phase Roll Vortices under a Moving Hurricane Boundary Layer
Authors: Gao Kun , Ginis Isaac
Published: May 2018

Previous theoretical and numerical studies only focused on the formation of roll vortices (rolls) under a stationary and axisymmetric hurricane. The effect of the asymmetric wind structure induced by the storm movement on the roll characteristics remains unknown. In this study, we present the first attempt to investigate the characteristics of linear-phase rolls under a moving hurricane by embedding a linear two-dimensional (2D) roll-resolving model into a 3D hurricane boundary layer model. It is found that the roll horizontal wavelength under the moving hurricane is largely determined by the radial-shear-layer depth, defined as the thickness of the layer with positive radial wind shear. The horizontal distribution of the roll wavelength resembles the asymmetric pattern of the radial-shear-layer depth. Interestingly, the roll growth rate is not only affected by the radial wind shear magnitude alluded to in previous studies but also by the radial-shear-layer depth. A deeper (shallower) radial shear layer tends to decrease (increase) the roll growth rate. Such an effect is due to the presence of the bottom boundary. The bottom boundary constrains the lower-level roll streamlines and reduces the efficiency of rolls in extracting kinetic energy from the radial shear. This effect is more pronounced under a deeper shear layer, which favors the formation of larger-size rolls. This study improves the understanding of the main factors affecting the structure and growth of rolls and will provide guidance for interpreting the spatial distribution of rolls under realistic hurricanes in observations and high-resolution simulations.
Mechanisms Governing the Development of the North Atlantic Warming Hole in the CESM-LE Future Climate Simulations
Authors: Gervais Melissa , Shaman Jeffrey , Kushnir Yochanan
Published: May 2018

A warming deficit in North Atlantic sea surface temperatures is a striking feature in global climate model future projections. This North Atlantic warming hole has been related to a slowing of the Atlantic meridional overturning circulation (AMOC); however, the detailed mechanisms involved in its generation remain an open question. An analysis of the Community Earth System Model Large Ensemble simulations is conducted to obtain further insight into the development of the warming hole and its relationship to the AMOC. It is shown that increasing freshwater fluxes through the Arctic gates lead to surface freshening and reduced Labrador Sea deep convection, which in turn act to cool Labrador Sea sea surface temperatures. Furthermore, the resulting changes in surface ocean circulation lead to enhanced transport of cooled Labrador Sea surface waters into the interior of the subpolar gyre and a more zonal orientation of the North Atlantic Current. As a result, there is an increase in ocean advective heat flux divergence within the center of the subpolar gyre, causing this warming deficit in North Atlantic sea surface temperatures. These local changes to the ocean circulation affect the AMOC and lead to its slowdown.
Linking the Medical and Educational Home to Support Children With Autism Spectrum Disorder: Practice Recommendations
Authors: Shahidullah Jeffrey D. , Azad Gazi , Mezher Katherine R. , McClain Maryellen Brunson , McIntyre Laura Lee
Published: May 2018

Children with autism spectrum disorder (ASD) present with complex medical problems that are often exacerbated by a range of other intellectual and psychiatric comorbidities. These children receive care for their physical and mental health from a range of providers within numerous child-serving systems, including their primary care clinic, school, and the home and community. Given the longitudinal nature in which care is provided for this chronic disorder, it is particularly necessary for services and providers to coordinate their care to ensure optimal efficiency and effectiveness. There are 2 primary venues that serve as a “home” for coordination of service provision for children with ASD and their families—the “medical home” and the “educational home.” Unfortunately, these venues often function independently from the other. Furthermore, there are limited guidelines demonstrating methods through which pediatricians and other primary care providers (PCPs) can coordinate care with schools and school-based providers. The purpose of this article is 2-fold: (1) we highlight the provision of evidence-based care within the medical home and educational home and (2) we offer practice recommendations for PCPs in integrating these systems to optimally address the complex medical, intellectual, and psychiatric symptomology affected by autism.

Published: May 2018

This work involves the study of the thermal, mechanical and physical properties of epoxy filled with nanoegg shell particles. Nanoegg shell particles of near uniform size and shape were prepared by high-speed ball milling technique. The influence of nanoegg shell particle concentration (1 to 5 wt.%) on epoxy curing rate, thermal stability, dynamic mechanical properties and the tensile, hardness, impact and water uptake properties was evaluated. The result showed improvement in most of these properties except for storage modulus in the rubbery phase. Microscopic examination revealed strong particle–matrix adhesion strength, with optimum improvement of all properties at 2 wt.% nanoegg shell filler concentration.
Modelling external shocks in a small open economy: the case of Ireland
Authors: Conefrey Thomas , O'Reilly Gerard , Walsh Graeme
Published: May 2018

The Irish economy has recovered at an impressive pace from the economic and financial crisis that lasted from 2008–12. Nonetheless, as a small open economy with some lingering vulnerabilities from the recent crisis, the economy remains heavily exposed to potential adverse shocks. In this paper, we explore the possible impact of external shocks on the Irish economy. We model the shocks in a two-stage process: first using NiGEM to estimate the impact on Ireland's key trading partners and the broader international environment and then examining the effect of these changes in the COSMO model of the Irish economy. The paper focusses on three relevant risks facing the economy: the potential for a hard Brexit, an increase in interest rates and a depreciation of the sterling euro exchange rate. Using this two-step approach allows us to demonstrate the transmission of external shocks to the Irish economy. The results help to quantify the potential impact on future growth, the labour market, public finances and the financial system of some key risks materialising.

Published: May 2018

In this study, to produce single-use bee-repellent fabrics, a variety of essential oils were encapsulated with gum arabic wall material at a 1:5 ratio of wall to the core substance. The following core substances were used: lavender oil, laurel oil, fennel oil, N, N-diethyl-3-methylbenzamide (DEET), lavender + laurel oil, lavender + fennel oil, laurel + fennel oil, lavender + fennel + laurel oil, lavender oil + DEET, fennel oil + DEET and laurel oil + DEET. Lavender, fennel and laurel oils were analyzed by high-performance liquid chromatography. In this context, 11 different microcapsules were produced. After the microencapsulation process, the microcapsules were analyzed with a light microscope and by Fourier transform infrared spectroscopy. Furthermore, an image processing application was developed and implemented to determine the particle size distribution of the microcapsules. After the analysis of the microcapsules, cotton fabric samples were treated with the microcapsules. In order to analyze the microcapsules on the fabric samples, scanning electron microscopy (SEM) was used. To analyze the bee-repellent abilities of the fabric samples, 12 different measurement cabinets made of pine tree and glass were produced. According to the results, lavender and fennel oils can be used as bee-repellent alternatives to DEET in beekeeping.
Steam impinging and heat and water spreading in fabrics
Authors: Liang Shuaitong , Pan Ning , Cui Yuexin , Wu Xiongying , Ding Xuemei
Published: May 2018

This study is about the heat and mass transport phenomena in a system with steam jet flow to eliminate/alleviate cloth wrinkles. We first adopted a theoretical approach to derive the mean capillary radii so that a fabric can be characterized as an assembly of capillary tubes with varying diameters. We then analyzed the processes as a heat transfer via the fibers and water via the pores in fabrics of different anisotropies. During water movement, the water weight actually intensifies the inherent anisotropy of the fabric in the water flow pattern. For heat transfer, the water weight becomes irrelevant and both convection and radiation are shown to be too trivial to include. Corresponding experiments are also conducted, using infrared and visible light cameras to record the heat and water flow processes, respectively. The results are compared with the theoretical predictions and the discrepancies are explored and explained.

Published: May 2018

We describe in this work a broadband magnetic E-shape piezoelectric energy harvester with wide frequency bandwidth. We develop first a nonlinear electromechanical model of the harvester based on the Hamilton variation principle that simulates the effect of the nonlinear magnetic restoring force at different spacing distances. The model is used to identify the distances existing between two different magnets that enable the system to perform with a specific nonlinearity. The performance of the E-shape piezoelectric energy harvester is also investigated through experiments, with E-shape energy harvesters at different spacing distances tested under several base acceleration excitations. We observe that the frequency domain output voltage of the system shows a general excellent controllable performance, with a widening of the frequency bandwidth. The half-power bandwidth of the linear energy harvester for a distance of 25 mm is 0.8 Hz only, which can be expanded to 2.67 Hz for the larger distance of 11 mm between magnets. The energy harvester presented in this work shows promising performances for broad-spectrum vibration excitations compared to conventional cantilever piezoelectric energy harvester systems with a tip mass.

Mycobacterial spindle cell pseudotumor (MSP) is a rare benign spindle cell lesion containing acid-fact mycobacteria. These lesions are most commonly identified in the lymph nodes, skin, spleen, or bone marrow of immunocompromised patients and only rarely involve the lungs. We report 3 cases of pulmonary MSP, which include 2 patients who are known to be HIV-positive. The histopathological diagnosis of MSP in the lung lends itself to many challenges due to its rare incidence and its spindled tumor-like appearance. The differential diagnosis is broad and includes both benign and malignant entities. We highlight the importance of the clinical context in which these lesions typically present and the morphologic spectrum of features seen, and we offer a practical approach to the workup of pulmonary mycobacterial pseudotumor. Appropriate recognition of this entity should lead to an accurate diagnosis of a treatable benign condition despite the clinical presentation often favoring malignancy.
Extranodal Rosai-Dorfman Disease With Mucosal Involvement of the Stomach in a Background of Autoimmune Atrophic Gastritis

Published: May 2018

Rosai-Dorfman disease (RDD), or sinus histiocytosis with massive lymphadenopathy, has been described involving both lymph nodes and extranodal sites, but extranodal RDD rarely involves the gastrointestinal tract. Although the etiology is unclear, several risk factors have been shown to be highly associated with this disease process, including viral infection and immune alterations. In this article, we present a case of a 79-year-old male with a history of autoimmune atrophic gastritis and multiple carcinoid tumors of the stomach presenting with a new stomach mass. An additional large sigmoid colon mass and adjacent enlarged lymph node was identified through imaging, prior to surgery. Through extensive pathologic analysis, we identified the first case of predominant extranodal RDD involving gastric mucosa and submucosa in a background of atrophic gastritis, with additional involvement of the sigmoid colon. Based on this case and literature review, we further discuss possible risk factors and pathogenesis of this disease process.
Shedding light on the dark social: The connective role of news and journalism in social media communities
Authors: Swart Joëlle , Peters Chris , Broersma Marcel
Published: May 2018

Messaging apps and Facebook groups are increasingly significant in everyday life, shaping not only interpersonal communication but also how people orient themselves to public life. These “dark social media” are important spaces for “public connection,” a means for bridging people’s private worlds and everything beyond. This article analyzes how people perceive news on such platforms, focusing on the different roles it plays in key social networks that rely on dark social media for communication. Arguing that the use of these platforms is foremost a social practice, the study employs focus groups with local, work, and leisure-related communities to investigate questions of inclusiveness, engagement, relevance, and constructiveness associated with sharing and discussing news. We find the perceived value of news on dark social media hinges on the control and privacy it provides. Community type was less significant than communicative aims of the group for shaping the uptake of news and journalism.
Disparate Impact? Race, Sex, and Credit Reports in Hiring
Authors: O’Brien Rourke L. , Kiviat Barbara
Published: May 2018

Half of U.S. employers consider credit history when deciding whom to hire. The practice has become a contentious policy issue, with multiple jurisdictions limiting the use of credit reports in employment. Yet to date, there has been no test of how the introduction of credit history influences the way employers make decisions. Recent qualitative research finds that employers evaluate credit reports in contingent and person-specific ways, which opens the door to bias according to applicant characteristics, such as race and sex. To test for potential disparate impact in employment outcomes from the use of credit reports, we conduct a survey experiment with 1,050 hiring professionals. We find that including a bad credit report in an applicant’s file reduces respondents’ likelihood of hiring female (vs. male) applicants and reduces the recommended starting salary offered to black (vs. white) applicants. We discuss the implications of this study for research and public policy.

Key Points

High NPM1-mutant allele burden at diagnosis is associated with poor clinical outcome in de novo AML. The adverse effect of high NPM1-mutant allele burden is independent of comutations and clinical variables.
Alternative Sources of the Gains from International Trade: Variety, Creative Destruction, and Markups
Authors: Feenstra Robert C.
Published: May 2018

The modern theory of international trade identifies several additional sources of the gains from international trade beyond the gains from traditional comparative advantage. These are the gains from importing new product varieties; the gains from “creative destruction” as the relatively most productive firms expand their output by exporting while the less-productive firms exit; and the gains from competition between firms in different countries, which can lead to reduced markups. Estimates of these various gains are provided for the United States and other countries.

A qualitative exploration of evidence-based decision making in public health practice and policy: the perceived usefulness of a diabetes economic model for decision makers
Authors: Grove Amy , Sanders Tom , Salway Sarah , Goyder Elizabeth , Hampshaw Susan
Published: May 2018

Purpose

The purpose of this paper is to explore the perceived usefulness of a diabetes economic model as a potential tool for aiding evidence-based decision making in public health.

Methods

Fifteen interviews and two focus groups, with four participants in each, were conducted with health and management professionals working in one public health department in a local council. Data were analysed using inductive thematic analysis to generate four themes.

Findings

The findings reflect attitudes and beliefs of a diverse staff group situated in public health services. Findings reveal that the economic model was perceived as useful and participants reported positive views regarding the principles of economic modelling for decision making. However, it was potentially problematic in practice due to organisational constraints linked to limited resources, restricted budgets and local priorities. Differences in institutional logics of staff working across public health and local government departments were identified as a potential barrier to the use of the model in practice.

Discussion

The findings highlight anticipated challenges that public health practice and policy decision-makers could face if they selected to implement an economic modelling approach to fulfil their evidence needs. Previous studies have revealed that healthcare decision makers would find evidence around the economic impacts of public health interventions useful, but this information was not always available in the format required. This paper provides insights into how public health staff perceive economic modelling, and explores how they use this type of evidence when making public health practice and policy decisions.
To live in light: Historical conversations in Michael John LaChiusa’s The Wild Party
Authors: Robinson Joshua
Published: May 2018

Michael John LaChiusa’s The Wild Party is notable for any number of reasons, particularly given that it was one of two adaptations of the John Moncure March poem premiering in New York City during the 1999–2000 season, the other being Andrew Lippa’s adaptation at Manhattan Theatre Club. LaChiusa’s adaptation is also notable for its racialized narrative, given that the central role of Queenie was recast, replacing an actress of colour – singer-actress Vanessa Williams – with a white actress, Oscar nominee Toni Collette. In this article, the implications of this casting change are explored, particularly the ways in which the change from an actress of colour to a white actress forced the musical into a historical conversation with the racialized conventions of vaudeville performance.

Association between oxygen saturation and critical congenital heart disease in newborns
Authors: Halim Lidia , Ali Muhammad , Sembiring Tiangsa
Published: May 2018

Background Critical congenital heart disease (CCHD) is relatively common, with a prevalence of 6-8 in every 1,000 live births. This congenital anomaly is a newborn condition that would be ideally suited for a screening program, if simple and reliable methods were available. Pulse oximetry (PO) has been proposed as a screening method to detect CCHD.

Objective To assess for a possible association between decreased oxygen saturation and CCHD in newborns.

Methods We conducted a cross-sectional study from March 2014 to February 2015 in several hospitals in North Sumatra. Healthy, full term and post-term newborns aged 2 to 72 hours underwent pulse oximetry measurements on the right hand and one of the lower extremities. If oxygen saturation (SpO2) was ≤ 95%, the measurement was repeated 2 more times. Subjects also underwent echocardiography.

Results A total of 386 newborns underwent SpO2 measurements: 377 newborns had SpO2 > 95% and 9 newborns had SpO2 ≤ 95%. Of the infants with SpO2 > 95%, 297 were excluded because their parents refused echocardiography examination. Thus, 80 newborns with SpO2 > 95% and 9 newborns with SpO2 ≤ 95% underwent echocardiography. Echocardiography revealed that 5 of 9 newborns with SpO2 ≤ 95% suffered from Tetralogy of Fallot (ToF) (3 subjects) and transposition of the great arteries (TGA) (2 subjects). One infant with SpO2 > 95% had ventricular septal defect (VSD), as detected by echocardiography. Oxygen saturation ≤ 95% had significant association with CCHD (P<0.001).

Conclusion Decreased oxygen saturation has a significant association with critical congenital heart disease in newborns.
