Retinal Scanning Display: Light Sources Moving over the Retina
Authors: De Wit Gerard C.
Published: May 2019

A retinal scanning display is a new kind of display that directly uses the retina as a projection screen. This differs from, for example, a TV which first creates an image on a screen outside the eye. Although a retinal scanning display needs no screen, the principle of creating an image is similar to that of a TV. Where the TV uses an electron beam to create (scan) a raster pattern on a screen, a retinal scanning display uses a beam of light to scan a raster pattern on the retina. The way to get from an equally illuminated raster pattern to an image is to modulate the intensity of the beam as it scans. Since the eye does not look at a physical screen, people often wonder what the image of a retinal scanning display will look like. Upon seeing the image, the general response is: ‘It looks just like a normal display’. In fact it is a normal display, but one that has many advantages compared to other kind of displays, such as: possibility of high brightness, large color gamut, possibility of high-resolution and good image quality.
Light Scattering Studies on Supersaturated Protein Solutions
Authors: Georgalis Yannis , Saenger Wolfram
Published: May 2019

The difficulties associated with protein crystallization is a major obstacle in modern structural biology. The increasing demand from the protein crystal structure community for quick and non-invasive experimental techniques as well as the rapid progress of modern optics and electronics have led during the past decade to a considerable expansion of the laser light scattering techniques. The latter are now very often employed to elucidate the aggregation kinetics of supersaturated protein solutions and the mechanism(s) underlying the early nucleation stages. The experimental verification of the nucleation processes, the prediction of the effective interaction potentials and the development of appropriate diagnostics schemes are discussed.
Dissection of the Class a Scavenger Receptor by Peptide Engineering
Authors: Suzuki Kazuo , Takano Tomoko Y. , Tanaka Toshiki
Published: May 2019

The construction of portions of a protein provides information about its functional mechanisms. Peptide engineering is a recently developed technique to construct a small tertiary structure or a portion of a protein, and allows expansion to applications for bio- and physicochemistries. In this article, we focus on the class A scavenger receptor, which plays a key role in atherogenesis, and may be involved in other pathogenic processes. The receptor is mainly composed of simple tertiary structures, such as collagen and α-helical coiled coil structures, which have different functions. We constructed both the collagen-like and α-helical coiled coil domains by peptide engineering, and analysed the structure-function relationships of the receptor. Understanding the mechanisms of their functions at the amino acid level should help us to mimic the functional domains and to create de novo designed proteins with new functions.
The Effects of Social Skills Interventions for Students With EBD and ASD: A Single-Case Meta-Analysis
Authors: Hutchins Nancy S. , Burke Mack D. , Bowman-Perrott Lisa , Tarlow Kevin R. , Hatton Heather
Published: May 2019

Social skills interventions are critical for promoting social, emotional, and behavioral competence for students with or at risk of emotional and behavioral disorders (EBD) and autism spectrum disorders (ASD). This single-case meta-analysis examined the effects of social skills interventions (SSIs) for students with EBD and ASD. Effect sizes were calculated for 78 cases across 25 included studies using a nonparametric effect size, Baseline Corrected Tau. The overall weighted mean effect size of 0.54 suggested a moderate effect across the 25 studies. The overall weighted mean effects for studies reporting maintenance and generalization data were 0.68 and 0.37, respectively. Potential moderators examined (disability, intervention design, intervention delivery, methodological quality) were not significant. As such, they did not moderate the outcomes for participants. We conducted a post hoc analysis and hypothesized that between-study differences may be more meaningful than the similarities shared by participants in the same moderator groups. Implications are discussed on using SSIs to address the social, emotional, and behavioral challenges of students with or at risk of EBD and ASD.
Comparison of short nozzle and long nozzle spray in sinonasal drug delivery: a cadaveric study
Authors: Kapadia Mustafa , Grullo Precious Eunice R. , Tarabichi Muaaz
Published: May 2019

The aim of this study is to compare the delivery site of topical drugs using the short nozzle and the long nozzle. Fourteen fresh frozen cadaver heads were obtained. All cadaver specimens underwent bilateral endoscopic wide maxillary antrostomy, frontal sinusotomy, and complete sphenoethmoidectomy. The right nasal cavity of each cadaver was sprayed with radiolabeled saline using the short nozzle (short nozzle group), while the left nasal cavity was sprayed using the long nozzle (long nozzle group). The distribution of radioactive saline within the sinus cavities was determined using single-photon emission computed tomography/computed tomography. The distribution of the radiolabeled saline in reference with the maxillary line, vestibule, maxillary, ethmoid, sphenoid, and frontal sinus was compared between the 2 groups using Fisher exact test. The number of specimens that demonstrated radioactivity above the maxillary line is higher in the long nozzle group (14 cadavers, 100%) compared to short nozzle group (9 cadavers, 64.3%; p = .02). There are fewer specimens that demonstrated deposition of radioactive saline in the vestibule in the long nozzle group (6 cadavers, 42.86%) compared to short nozzle group (13 cadavers, 92.86%; P = .006). Compared to short nozzle group, there are more specimens demonstrating radioactivity in the maxillary, ethmoid, sphenoid, and frontal sinus in the long nozzle group, but the differences were not statistically significant ( p = 0.241, 0.347, 0.126, 0.5). Compared to short nozzle, long nozzle more frequently delivers intranasal drugs beyond the maxillary line and less frequently in the vestibule. These findings support the hypothesis that the use of long and narrow nozzle, instead of the conventional short nozzle, can improve sinonasal drug delivery in post-endoscopic sinus surgery nose.

Published: May 2019

Vertebral metastases of non-small cell lung cancer (NSCLC) are frequently diagnosed in the metastatic setting and are commonly identified in the thoracic vertebrae in patients. Treatment of NSCLC bone metastases, which are often multiple, is palliative, and the median survival times are 3 to 6 months. We have characterized spontaneous vertebral metastases in a brain metastases model of NSCLC and correlated these findings with epithelial–mesenchymal transition (EMT). Brain metastases were established in athymic nude mice following intracardiac injection of brain-seeking adenocarcinoma NSCLC cells. Thirty-nine percent of mice (14/36) developed spontaneous vertebral metastases, spinal cord compression, and hind-limb paralysis. Vertebral metastases consisted of an adenocarcinoma phenotype with neoplastic epithelial cells arranged in cords or acini and a mesenchymal phenotype with spindloid neoplastic cells arranged in bundles and streams. Quantitative and qualitative immunohistochemical and immunofluorescence assays demonstrated an increase in vimentin expression compared to cytokeratin expression in vertebral metastases. A correlation with EMT was supported by an increase in CD44 in vertebral metastases and parenchymal metastases. These data demonstrate a translational lung cancer metastasis model with spontaneous vertebral metastasis. The mesenchymal and epithelial phenotype of these spontaneous metastases coupled with EMT provide a conduit to improve drug delivery and overall patient survival.
Money talks: The finances of English Combined Authorities
Authors: Sandford Mark
Published: May 2019

The mayoral combined authorities created in England in the mid-2010s were hailed as a new form of territorial governance, tasked with driving economic growth in city regions. Much debate has ensued about the nature, potential and reach of the new organisations, located in a complex web of governance networks, but lacking an explicit policy rationale or clearly identified territorial boundaries. This article examines the funding and financial arrangements of the new bodies, as these embody the character of central–local relationships; these in turn are the critical influence on the activities and priorities of mayoral combined authorities in England. It argues that central government funding transfers are assuming a disproportionate influence on the functions and priorities of mayoral combined authorities, due to the metagovernance framework within which they operate. This incentivises them to develop into ‘grant coalitions’, seeing central funds as the only available route to local impact.
Feasibility of a traditional and teletreatment approach to mirror therapy in patients with phantom limb pain: a process evaluation performed alongside a randomized controlled trial
Authors: Rothgangel Andreas , Braun Susy , Smeets Rob , Beurskens Anna
Published: May 2019

Objective:

To evaluate the delivery, acceptance and experiences regarding a traditional and teletreatment approach to mirror therapy as delivered in a randomized controlled trial.

Design:

Mixed methods, prospective study.

Setting:

Rehabilitation centres, hospital and private practices.

Subjects:

Adult patients with phantom pain following lower limb amputation and their treating physical and occupational therapists.

Interventions:

All patients received 4 weeks of traditional mirror therapy ( n = 51), followed by 6 weeks of teletreatment ( n = 26) or 6 weeks of self-delivered mirror therapy ( n = 25).

Main measures:

Patient files, therapist logs, log files teletreatment, acceptance questionnaire and interviews with patients and their therapists.

Results:

In all, 51 patients and 10 therapists participated in the process evaluation. Only 16 patients (31%) received traditional mirror therapy according to the clinical framework during the first 4 weeks. Between weeks 5 and 10, the teletreatment was used by 14 patients (56%) with sufficient dose. Teletreatment usage decreased from a median number of 31 (weeks 5–10) to 19 sessions (weeks 11–24). Satisfactory teletreatment user acceptance rates were found with patients demonstrating higher scores (e.g. regarding the usefulness to control pain) than therapists. Potential barriers for implementation of the teletreatment perceived by patients and therapists were related to insufficient training and support as well as the frequency of technical problems.

Conclusion:

Traditional mirror therapy and the teletreatment were not delivered as intended in the majority of patients. Implementation of the teletreatment in daily routines was challenging, and more research is needed to evaluate user characteristics that influence adherence and how technology features can be optimized to develop tailored implementation strategies.
The Femme Fatale in Vogue: Femininity Ideologies in Fin-de-siècle America
Authors: Minowa Yuko , Maclaran Pauline , Stevens Lorna
Published: May 2019

This article explores how marketing influences ideologies of femininity. Tracing the evolution of femme fatale images in Vogue magazine in 1890s America, we develop a typology around four archetypal forms of the femme fatale that prevailed during this period. In doing so we respond to calls for more critical historical analyses on femininity. While studies on masculinity ideologies proliferate, there is a paucity of research on dissonant representations of femininity in popular culture media. The femme fatale, often a self-determined seductress who causes anguish to the men who become involved with her, is an intriguing and enduring challenge to traditional notions of femininity. Thus, in studying the femme fatale in her historical context and revealing the multiplicity of feminine ideologies contained within this trope, we contribute to a deeper understanding of marketing’s role in both reflecting and reinforcing societal assumptions, attitudes and problematics around gender norms.
Using everyday engineering examples to engage learners on a massive open online course
Authors: Patterson Eann A
Published: May 2019

A massive open online course on the laws of thermodynamics has been designed using the 5Es (Engage, Explore, Explain, Elaborate, Evaluate) lesson planning methodology and delivered using everyday engineering examples to provide familiar contexts for both a global cohort of more than 3000 learners ranging in age from teenagers to septuagenarians in 137 different countries plus a large class of 355 university undergraduates. In addition to the structured pedagogy, the massive open online course included innovations in the use of practical exercises, that could be performed in the learner’s kitchen, and worked examples to enhance the learning experience. The massive open online course was provided in parallel with an introductory undergraduate course and as an additional learning resource for the undergraduate students. A little less than one-fifth of the undergraduates participated in the massive open online course and just over half of these responded that it would be an acceptable substitute for traditional lectures. The percentage completing the massive open online course was relatively high at 28% compared to 21% for other massive open online courses on the same platform, which is attributed to the pedagogy and strong support for social learning based on a survey of fully participating learners in the last week of the five-week course.
Advancing scholarly publishing through open access biomedical repositories: A knowledge management perspective
Authors: Kruesi Lisa , Tanner Kerry , Burstein Frada
Published: May 2019

Scholarly publishing has undergone major changes over the past 50 years. Funder mandates and organisational reporting obligations have heralded the creation of open access repositories, such as institutional and subject repositories. This research draws upon the US PubMed Central (PMC) and Europe PMC, also known as PMC International, as a role model to inform the concept and opportunity for an Australasia open access biomedical repository. PMC International is a leader in making citations and research output, which link to research data, Findable, Accessible, Interoperable and Reusable (FAIR). As repositories approach two decades of development, this paper reports on the potential for an Australasia open access biomedical repository through a knowledge management lens and explores the opportunities for future open access biomedical repositories.
Evaluation of the Effectiveness on the Implementation of a Two-Way Left-Turn Lane with Educational Material in Highway PR-107 using a Driving Simulator
Authors: García Ricardo , Valdés Didier , Figueroa-Medina Alberto M.
Published: May 2019

The road diet concept has been implemented around the United States for more than three decades. Road diets are at the early stages of implementation in Puerto Rico and the use of a Two-Way Left Turn Lane (TWLTL) will be a new and unfamiliar design for local drivers. For this reason, the effectiveness of a TWLTL was evaluated using a driving simulator with local drivers for a segment of highway PR-107 in Puerto Rico. This highway is a suburban commercial corridor without access control that had a 67% increase in crashes between 2015 and 2016. This highway was selected because of its large number of left-turn maneuvers and more than 40% of the total crashes were rear-end type crashes. The University of Puerto Rico at Mayaguez Driving Simulator was used to evaluate drivers’ performance by observing vehicle speeds and positions along two simulated road scenarios: 1) the existing cross-section and 2) a modified cross-section with a TWLTL. Subjects were divided into two groups: 1) subjects who received training about the correct operation on a TWLTL before the simulation runs and 2) subjects who did not receive any prior training. The results indicate a positive effect of the educational material on driver behavior. Subjects who received training about the TWLTL showed a 66% increase in maneuver improvement, less variability in the position at which they entered the TWLTL, and lower variance of the mean speed than those who did not receive TWLTL training before driving through the simulation.
Identifying Fatality Risk Factors for the Commercial Vehicle Driver Population
Authors: Islam Mouyid , Ozkul Seckin
Published: May 2019

Commercial/large-truck fatal crash involvement by drivers of different age groups is a critical issue for the trucking industry. Escalating safety concerns related to these heavy vehicles serving the freight economy in the U.S. have an impact national freight reliability and economic growth. This study identifies major contributing factors leading to large-truck fatal crashes for four age groups of driver: <30, 30–49, 50–65, and 65+. The analysis in this study is based on five years (2012–2016) of Fatality Analysis Reporting System data and provides an overall picture of risk factors in large-truck fatal crashes. In total, 30 variables were found to be significant in the logit models, indicating varying risks associated with large-truck drivers of these four age groups. Model results indicate different risk factors associated with driver characteristics, spatial and temporal characteristics, vehicle and vehicle maneuvering characteristics, and environmental conditions at the time of the crashes. Identifying the risk factors for different age groups of drivers is important so proper countermeasures can be implemented from the perspective of human factors (e.g., safe speed choice, fatigue), roadway engineering (e.g., design of roadside barriers, radius of ramps), enforcement (e.g., presence of law enforcement personnel at critical locations), and emergency medical attention in remote areas. Considering the aging of the truck driver population in the U.S. and around the world, the findings of this study are vital to understand better the importance of safety in relation to large-truck fatal crashes.
Regional and Local Economic Effects from Proximity of High-Speed Rail Stations in Japan: Difference-in-Differences and Propensity Score Matching Analysis
Authors: Wetwitoo Jetpan , Kato Hironori
Published: May 2019

This paper gives empirical evidence about the economic effects of the proximity of high-speed rail (HSR) on regional/local production and labor productivity in Japan. The effects on regional and local scales are analyzed based on a Difference-in-Differences (DID) method and a Propensity Score Matching (PSM) method. The prefecture-level analysis investigates the effect on regional production at the prefecture level from 1981 to 2006 and the municipality-level analysis investigates the effect on the local tax revenue and the tax revenue per capita at the municipality level, particularly focusing on new HSR extensions between 2010 and 2015. The results from both levels showed statistically insignificant estimations of both the DID effect and the Average Treatment effect on the Treated from PSM, which implies that, on average, there is no direct effect from the proximity to HSR services on regional or local production or productivity. One of the potential reasons, the range of the distance from the HSR services at which the impact on the local economy is felt, is discussed. Further analysis showed that the range at which HSR services have an impact on local tax revenue per payer could vary from 10 to 30 km, depending on local characteristics in the location of the HSR station.
Platoon of SAE Level-2 Automated Vehicles on Public Roads: Setup, Traffic Interactions, and Stability
Authors: Knoop Victor L. , Wang Meng , Wilmink Isabel , Hoedemaeker D. Marika , Maaskant Mark , Van der Meer Evert-Jeen
Published: May 2019

An increasing amount of vehicles are equipped with driver assistance systems; many of the vehicles currently on the market can be optionally equipped with adaptive cruise control and lane centering systems. Using both systems at the same time brings the vehicle to SAE level-2 automation . This means a driver does not need to perform longitudinal and lateral operational driving, although the driver should be ready to intervene at any time. While this can provide comfort, the interaction between vehicles operated by these systems might cause some undesired effects. This becomes particularly relevant with increasing market penetration rates. This paper describes an experiment with seven SAE level-2 vehicles driven as a platoon on public roads for a trip of almost 500 km. The paper discusses how the experiment was organized and the equipment of the vehicles. It also discusses the interaction of the platoon in traffic, as well as, in basic terms, the interaction between the automated vehicles. The experiences can be useful for other studies setting up field tests. The conclusion from this platoon test is: intentionally creating platoons on public roads is difficult in busy traffic conditions. Moreover, interactions between the vehicles in the platoon show that the current SAE level-2 systems are not suitable for driving as platoons of more than typically three to four vehicles, because of instabilities in the car-following behavior.
The Big Three Perfectionism Scale: Factor Structure and Measurement Invariance in a Turkish Sample
Authors: Kilmen Sevilay , Arikan Serkan
Published: May 2019

Perfectionism is a crucial concept in psychology as perfectionism has been found to be related to many important factors affecting daily and academic life. Many researchers have tried to measure perfectionism since 1980. Following an extensive literature review, Smith, Saklofske, Stoeber, and Sherry developed a new perfectionism scale called Big Three Perfectionism Scale (BTPS). The present study addressed the validation study of the BTPS in Turkish sample. The factor structure of the BTPS and measurement invariance across gender groups was tested with the Turkish sample. The BTPS was administered to 609 undergraduate students studying in different departments. Reliability analyses showed that the Turkish version of the scale had an excellent internal consistency. Data from Turkey demonstrated acceptable fit to the three-factor, 10-facet structure of BTPS. The results also indicated that there was no significant difference between fit indexes of configural, metric, and scalar invariance across gender.
Mapping Workplace Neighborhood Mobility Among Sex Workers in an Urban Canadian Setting: Results of a Community-Based Spatial Epidemiological Study From 2010-2016

Published: May 2019

Mobility among sex workers has been linked not only to improved economic and social opportunities, but also to concerns regarding displacement, criminalization, and violence. In 2014, new “end-demand” legislation criminalized new aspects of sex work in Canada (e.g., third-party advertising, purchasing) while leaving the sale of sex legal. Utilizing data from a longitudinal community-based cohort of women sex workers in Metro Vancouver (An Evaluation of Sex Workers Health Access [AESHA], 2010-2016), we used kernel density mapping to understand and identify geographic patterns of workplace neighborhood mobility (i.e., changing the primary neighborhood in which one worked in the last 6 months); multivariable logistic regression using generalized estimating equations was also used to model contextual (policing, violence, and safety) and individual correlates of workplace mobility among sex workers over the 6-year period, including potential changes in mobility patterns pre- and post-end-demand criminalization. A total of 543 sex workers were included in analyses, contributing 2,199 observations. A total of 402 (74.0%) experienced workplace neighborhood mobility during the study period. Neighborhood mobility was negatively correlated with age (adjusted odds ratio [AOR] = 0.98/year older, 95% confidence interval [CI] = [0.97, 0.99]) and positively correlated with homelessness (AOR = 1.43, 95% CI = [1.12, 1.82]), identifying as a gender/sexual minority (AOR = 1.31, 95% CI = [1.04, 1.70]), and servicing clients primarily outdoors (vs. informal indoor or in-call venues; AOR = 1.48, 95% CI = [1.21, 1.81]); police harassment (AOR = 1.19, 95% CI = [0.96, 1.48], p = .11) and changing one’s neighborhood of work due to safety concerns (AOR = 1.37, 95% CI = [0.94, 2.00], p = .09) were both marginally correlated. Steps to promote safer working conditions for marginalized women in urban environments remain urgently needed, including shifts away from criminalized enforcement toward community-led initiatives and promoting access to safer indoor workspaces.
LatinX studies: Variations and velocities
Authors: Milian Claudia
Published: May 2019

At the core of this Cultural Dynamics special issue on “LatinX Studies: Variations and Velocities” are new conceptual approaches, epistemological workings, “keywords,” and modes of inquiry that enable us to theorize LatinX Studies and global LatinXness for the twenty-first century. Bringing together different research communities from art, art history, cultural anthropology, cultural studies, geography, history, journalism, and literature, this exploratory undertaking offers a working language on present-day LatinX preoccupations to seize what is happening contemporaneously in light of the field’s “X” and to disseminate it in a usable format like this journal. The volume’s contributors—Jill Anderson, Gloria Elizabeth Chacón, Nicholas De Genova, María DeGuzmán, Rene Galvan, Hilda Lloréns and Maritza Stanchich, Mark Overmyer-Velázquez, and Fredo Rivera—put forward new formulations and models for Latino/a Studies in considering LatinX geographies beyond the Americas; indigenous migrations and cultural production; Miami’s oceanic borderlands; environmental planetary problems and environmental knowledges; LatinX medical subjects; and deported exiles. The breadth of foci herein invites further problematization and dialogue with implications and relevance to other fields.
Precarity + excess in the latinopolis: Miami as Erzulie
Authors: Rivera Fredo
Published: May 2019

Miami’s built and natural environment, together with the politics of migration, has transformed it into a major global city and art center over the past decades. This article situates Miami—generally viewed as an aspirational city and cultural nexus of the Americas—as an oceanic borderlands lying between political and ecological precarity as well as economic and cultural excess. This article examines the relationship of contemporary art and the urban landscape to consider Miami’s unique place for thinking about LatinX and Latin America today. Building on Gloria Anzaldúa’s theorizing on borderlands and creative expression as a framework and drawing inspiration from the Vodou pantheon of Erzulie, this essay analyzes Miami through a queer and Caribbean lens. New high-rises, prominent museums, and public art installations exemplify the rise of the neoliberal city and its inherent contradictions. The work of prominent local and international artists such as Edouard Duval-Carrié, Jeanne-Claude & Christo, Glexis Novoa, and Alfredo Jaar is explored as a window for considering Miami’s cultural production. Miami is a model of tropical urbanity. Its social, political, and economic conditions belie this city’s status as global cultural capital.

The writing profession in France: Between symbolic and professional recognition
Authors: Sapiro Gisèle
Published: May 2019

This article examines current transformations of the writing profession in France. Based on qualitative research (interviews with writers and their representatives, as well as organisers of literary events) and on a national survey conducted in 2016 by the Centre national du livre, it emphasises the tension between symbolic and professional recognition at different moments of a writer’s ‘career’. In a country where literary agents are only now starting to organise, and where creative writing courses are not as well established as elsewhere, publishers still play the key role of ‘gatekeepers’ into the literary field. The relationship with the publisher is thus crucial and is based on elective affinities. Yet, once published, an author still needs to be distinguished and recognised. Apart from the traditional literary prizes, which give symbolic and professional recognition, literary events (festivals, public readings) and residencies offer new career opportunities. These related activities, or ‘activités connexes’ have significantly increased in number: the article focuses especially on analysing how they now fit into and structure the literary careers of authors, as well as how authors themselves perceive them.
Shame, silence and resistance: How my narratives of academia and kidney disease entwine
Authors: Richards Rose
Published: May 2019

As an academic with a chronic illness, it has taken me a while to understand shame’s impact on my academic identity and choices. In this article, through a process of narrative recuperation, I consider the challenges and contradictions of living as an academic with chronic kidney disease, an incurable and often debilitating illness that, for the most part, is invisible to others. By means of evocative autoethnography, I trace the trajectory of silencing shame I experienced around my condition in academia and I show how and why this changed over a number of years. My aim in doing this is to uncover subjugated knowledge of what it takes to live as a chronically ill academic and to be an advocate for other academics living with chronic illness. I theorise my study using Garland-Thomson, Shildrick and Leder, all of whom have worked with the othering effect of shame on the nonconforming body. These theorists have described ways of resisting shame and, partly thanks to them, I was able to find ways of fighting back and recovering. My intention in sharing these illness narratives is to speak back to a dominant discourse that favours invulnerability and a masculinised, disembodied way of being academic.

BRICS Nations and Income Convergence: An Insight from the Quarterly Data for 2006Q1–2017Q2
Authors: Das Ramesh Chandra , Das Utpal , Das Amaresh
Published: May 2019

The formation of the BRICS Group was aimed at, among others, developing parallel economic power house of the highly emerging nations and generating additional shock absorbing capacity. Maintaining equitable distribution of income and wealth among the group members, thus, was one of the top most priorities of the group. Under this backdrop, the present study examines whether the countries are converging in income leading to overall development in the group. Applying the neoclassical growth and panel unit roots models on the quarterly data from 2006Q1–2017Q2 to 2009Q1–2017Q2, the study reveals that there is no significant catching up of the countries in both the periods, but there is conditional convergence in the first period. The variables which played conditional roles are net FDI inflow and crude oil production. Further, the study observes sigma convergence among the group members in both the periods, signifying that the cross-country income differences have been going down over time.
Intergroup Dialogue: A Review of Recent Empirical Research and Its Implications for Research and Practice
Authors: Frantell Keri A. , Miles Joseph R. , Ruwe Anne M.
Published: May 2019

Intergroup dialogue (IGD) is a small group intervention that allows for sustained communication between people across social identity groups. It aims to foster intergroup relationships, develop critical consciousness, and increase capacities for promoting social justice. A decade after Dessel and Rogge published their review of the empirical research on IGD from 1997 to 2006, we reviewed the empirical IGD research from 2006 to 2017. We explore research that has examined IGD outcomes, processes, and facilitation, seeking to understand the current state of the research and practice of IGD. We discuss advances and new approaches to IGD, assess growth since Dessel and Rogge’s review, and discuss future directions. We provide five key recommendations for future research on IGD, and five key recommendations for future practice of IGD.
Micro-CT-based micromechanics and numerical homogenization for effective elastic property of ultra-high performance concrete
Authors: Luo Qi , Liu Dongxu , Qiao Pizhong , Zhou Zhidong , Zhao Yanlin , Sun Lizhi
Published: May 2019

A computational homogenization model using microstructures obtained from X-ray micro-CT is developed to estimate the porosity-based elastic properties of ultra-high performance concrete under freeze–thaw action. The model is transformed directly from micro-CT which is capable of reflecting realistic distribution of porosity and heterogeneities inside the ultra-high performance concrete. Factors are taken into consideration, including the determination of representative volume element, the position and numbers of representative volume element cubes, fiber orientation, image resolution, applied filter, and pore distribution. The relationship between the material internal structure and freeze–thaw resistance is studied at micro-scale. The volume-averaged homogenization approach is applied to calculate the effective properties of the ultra-high performance concrete which are compared with experimental data. It is demonstrated that the proposed model provides an effective tool to evaluate the elastic properties of the ultra-high performance concrete based on microstructural characterization data.

In this response to the essays by Saarinen, Fowl, Harink, and Hill, five topics are addressed: the nature of ‘perfections’; the Christ-event and the Being of God; the justice of God; the moral agency of the believer; and the multiple dimensions of the incongruity of grace.
3D structure–2D plate interaction model
Authors: Ljulj Matko , Tambača Josip
Published: May 2019

In this paper, we derive models for the interaction of a linearized three-dimensional elastic structure with a thin elastic layer of possibly different material attached to it. Rigorous derivation is performed by considering a thin three-dimensional layer and the asymptotics of the solution of the full remaining three-dimensional problem when the thickness [Formula: see text] of the thin layer tends to zero. Furthermore, the attached thin material is assumed to have the elasticity coefficients which are of order [Formula: see text], for [Formula: see text] with respect to the coefficients of the three-dimensional body. In the limit, five different models are obtained with respect to different choices of p, namely [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text]. Furthermore a three-dimensional–two-dimensional model is proposed that has the same asymptotics as the original three-dimensional problem. This is convenient for applications because one does not have to decide in advance which limit model to use.

Publications of note from 2018 are reviewed for the cardiothoracic transplant anesthesiologist. Strategies to expand the availability of donor organs were highlighted, including improved donor management, accumulating experience with increased-risk donors, ex vivo perfusion techniques, and donation after cardiac death. A number of reports examined posttransplant outcomes, including outcomes other than mortality, with new data-driven risk models. Use of extracorporeal support in cardiothoracic transplantation was a prominent theme. Major changes in adult heart allocation criteria were implemented, aiming to improve objectivity and transparency in the listing process. Frailty and prehabilitation emerged as targets of comprehensive perioperative risk mitigation programs.
Police Chief Turnover in Texas: An Exploratory Analysis of Peer-Evaluation Survey Data Pertinent to Police Performance and Turnover
Authors: Li Yudu , Brown Ben
Published: May 2019

Turnover of police chiefs is brisk, with the average tenure of a chief of police ranging from 4 to 6 years, but few scholars have examined factors which may impact police chief turnover. This study contributes to the literature on police chief turnover via an examination of the impact that two forms of performance—leadership performance and departmental performance—may have on police chief turnover. Analyzed herein are peer-evaluation survey data and administrative data obtained from the Law Enforcement Management Institute of Texas and the Texas Commission of Law Enforcement. Regression analyses of the data suggest that leadership and departmental performance are associated with turnover, with leadership performance having the larger impact. Time in office, being an external appointment/hire, and having been hired by a city mayor also proved to significantly affect turnover. The policy and personal life-choice implications of the data for police officials and policy makers are discussed, as are the methodological implications.
Oncogenic Roles and Inhibitors of DNMT1, DNMT3A, and DNMT3B in Acute Myeloid Leukaemia
Authors: Wong Kah Keng , Lawrie Charles H , Green Tina M
Published: May 2019

Epigenetic alteration has been proposed to give rise to numerous classic hallmarks of cancer. Impaired DNA methylation plays a central role in the onset and progression of several types of malignancies, and DNA methylation is mediated by DNA methyltransferases (DNMTs) consisting of DNMT1, DNMT3A, and DNMT3B. DNMTs are frequently implicated in the pathogenesis and aggressiveness of acute myeloid leukaemia (AML) patients. In this review, we describe and discuss the oncogenic roles of DNMT1, DNMT3A, and DNMT3B in AML. The clinical response predictive roles of DNMTs in clinical trials utilising hypomethylating agents (azacitidine and decitabine) in AML patients are presented. Novel hypomethylating agent (guadecitabine) and experimental DNMT inhibitors in AML are also discussed. In summary, hypermethylation of tumour suppressors mediated by DNMT1 or DNMT3B contributes to the progression and severity of AML (except MLL-AF9 and inv(16)(p13;q22) AML for DNMT3B), while mutation affecting DNMT3A represents an early genetic lesion in the pathogenesis of AML. In clinical trials of AML patients, expression of DNMTs is downregulated by hypomethylating agents while the clinical response predictive roles of DNMT biomarkers remain unresolved. Finally, nucleoside hypomethylating agents have continued to show enhanced responses in clinical trials of AML patients, and novel non-nucleoside DNMT inhibitors have demonstrated cytotoxicity against AML cells in pre-clinical settings.
Forecasting tourism demand using search query data: A hybrid modelling approach
Authors: Wen Long , Liu Chang , Song Haiyan
Published: May 2019

Search query data have recently been used to forecast tourism demand. Linear models, particularly autoregressive integrated moving average with exogenous variable models, are often used to assess the predictive power of search query data. However, they are limited by their inability to model non-linearity due to their pre-assumed linear forms. Artificial neural network models could be used to model non-linearity, but mixed results indicate that their application is not appropriate in all situations. Therefore, this study proposes a new hybrid model that combines the linear and non-linear features of component models. The model outperforms other models when forecasting tourist arrivals in Hong Kong from mainland China, thus demonstrating the advantage of adopting hybrid models in forecasting tourism demand with search query data.
Forecasting tourist arrivals using multivariate singular spectrum analysis
Authors: Saayman Andrea , de Klerk Jacques
Published: May 2019

The accurate forecasting of tourist arrivals has become a necessity for destination managers and tourism businesses. Singular spectrum analysis (SSA) has been applied in other areas, although its application in tourism demand is limited to SSA using a single univariate time series. New developments in the field extend the univariate framework into a multivariate SSA (MSSA). This article aims to forecast tourist arrivals from five continents to South Africa using MSSA and to compare the forecasting accuracy with that of univariate SSA as well as the baseline seasonal naïve model. The results show that in all but one case, MSSA leads to improved forecasting accuracy compared to univariate SSA and that these improvements are especially prevalent when forecasting over longer time horizons.
Evaluation of Gender Mainstreaming
Authors: Bustelo Maríaa
Published: May 2019

The new policy strategy of ‘gender mainstreaming’ poses particular challenges for the evaluation of public gender-equality policies. To elaborate on this issue, a first step is to analyse the evaluation of those public gender-equality policies that have formally adopted the gender mainstreaming strategy. In this article, results are summarized from a meta-evaluation of 11 evaluation processes of gender-equality plans implemented between 1995 and 1999, both at regional and national levels in Spain. This meta-evaluation focused on analysing the evaluation processes rather than the outcomes of those evaluations. First, the different types of evaluation carried out in the 11 studies are discussed. Second, some contextual factors are identified as influencing elements in the evaluations. Third, some conclusions and lessons learnt are presented, using the framework provided by the meta-evaluation criteria previously established. Finally, taking into account those lessons, a discussion of the evaluation of gender mainstreaming is presented, elaborating on the ways in which gender mainstreaming strategies and gender perspective can be evaluated and which should be used to conduct useful evaluations.
Patient disempowerment through the commercial access to digital health records
Authors: Ebeling Mary FE
Published: May 2019

In this article, I consider how patients are disempowered through the commercial access to their health data in the United States. I examine two healthcare information technology bills that ostensibly give patients access and control over their health records. However, I contend that, since these regulations were drafted, in part or in whole, by corporate interests represented by healthcare lobbyists, policymakers use the rhetorical device of patient empowerment to allow for the commercial access to patient data, which ultimately disempowers patients. This is because in both bills the asymmetrical relationship to patient data remains the same: patients do not have ownership or control over the data that they produce. Rather, policymakers legislatively cede control over patient data to commercial interests.
Assessment of the validity of RANS knock prediction using the resonance theory
Authors: Netzer Corinna , Seidel Lars , Ravet Frédéric , Mauss Fabian
Published: May 2019

Following the resonance theory by Bradley and co-workers, engine knock is a consequence of an auto-ignition in the developing detonation regime. Their detonation diagram was developed using direct numerical simulations and was applied in the literature to engine knock assessment using large eddy simulations. In this work, it is analyzed if the detonation diagram can be applied for post-processing and evaluation of predicted auto-ignitions in Reynolds-averaged Navier–Stokes simulations even though the Reynolds-averaged Navier–Stokes approach cannot resolve the fine structures resolved in direct numerical simulations and large eddy simulations that lead to the prediction of a developing detonation. For this purpose, an engine operating point at the knock limit spark advance is simulated using Reynolds-averaged Navier–Stokes and large eddy simulations. The combustion is predicted using the G-equation and the well-stirred reactor model in the unburnt gases based on a detailed gasoline surrogate reaction scheme. All the predicted ignition kernels are evaluated using the resonance theory in a post-processing step. According to the different turbulence models, the predicted pressure rise rates and gradients differ. However, the predicted ignition kernel sizes and imposed gas velocities by the auto-ignition event are similar, which suggests that the auto-ignitions predicted by Reynolds-averaged Navier–Stokes simulations can be given a meaningful interpretation within the detonation diagram.
Different ways of seeing: Exploring audience reactions to images of probation supervision
Authors: Healy Deirdre , Fitzgibbon Wendy
Published: May 2019

Participatory visual research methods like Photovoice have become increasingly popular in social science research over the past two decades. While the benefits for co-researchers are well-established, audience studies remain relatively scarce. This represents an important gap in knowledge, especially since advocacy for social change is regarded as a core goal of Photovoice research. The authors aim to contribute to the nascent audiencing literature by exploring the responses from an audience of criminal justice stakeholders to an exhibition of photographs produced by people under probation supervision in Dublin, Ireland. The discussion begins with a critical reflection on the researchers’ experience of curating a Photovoice exhibition. Next, audience responses to the images are explored, including the extent to which intended messages reached the target audience and encouraged them to reflect more deeply on the meaning of supervision. Finally, the implications for audiencing studies are considered, particularly the challenge of managing inter-subjectivities in the data analysis process.
