AbstractThe [111]‐oriented rhombohedral Mn‐doped 0.15Pb(In1/2Nb1/2)‐0.55Pb(Mg1/3Nb2/3)O3‐0.30PbTiO3 (Mn:PIMNT(15/55/30)) crystal and the [001]‐oriented tetragonal Mn‐doped 0.29Pb(In1/2Nb1/2)‐0.29Pb(Mg1/3Nb2/3)O3‐0.42PbTiO3 (Mn:PIMNT(29/29/42)) crystal were poled under different conditions. The pyroelectric performance of the two crystals as a function of poling temperature, as well as the relationship with ferroelectric domain configuration and phase structure was investigated systematically. The pyroelectric properties of the two crystals enhance with rising the poling temperature, which can be attributed to the improvement of the single state. And for the rhombohedral Mn:PIMNT(15/55/30) crystal locating near morphotropic phase boundary (MPB), the increase of tetragonal phase induces the deterioration of pyroelectric properties. Due to more residual tetragonal phase, the pyroelectric coefficient of the Mn:PIMNT(15/55/30) crystal poled at 150°C is lower than that poled at 100°C. In general, both the crystals poled above TC achieve nearly single state, exhibiting the best pyroelectric properties with relatively high Curie temperature (TC), where P = 9.71 × 10−4 C m−2 K−1, Fi = 3.88 × 10−10 m V−1, Fv = 0.068 m2 C−1 and Fd = 29.7 × 10−5 Pa−1/2 for the rhombohedral Mn:PIMNT(15/55/30) crystal (TC = 171°C) and P = 6.78 × 10−4 C m−2 K−1, Fi = 2.71 ×10−10 mV−1, Fv = 0.1 m2 C−1, Fd = 23.54 × 10−5 Pa−1/2 for the tetragonal Mn:PIMNT(29/29/42) single crystal (TC = 251°C), meeting the stable operation of infrared detector at relatively high environmental temperatures.

Published: December 2019

AbstractTransparent Nd3+,Gd3+‐codoped SrF2 laser ceramic was fabricated by a single‐crystal ceramization (SCC) technique, and the fluorescence properties were also characterized. The results indicated that the SCC process would lead to reducing fluorescence properties of ceramic by re‐clustering small amount of Nd3+ ions. In this study, the re‐clustering of Nd3+ ions were addressed by a simple thermal drive‐induced grains regrowth (TDIGR) treatment. The properties of the Nd3+,Gd3+‐codoped SrF2 laser ceramic undergo the TDIGR were improved and close to precursor Nd3+, Gd3+‐codoped SrF2 single crystal. Meanwhile, the transmittance of ceramic (Taverage@400‐1400nm ~ 92%) was hardly affected by the TDIGR treatment. Therefore, we have reasons to believe that the combination of SCC and TDIGR is a suitable approach to obtain high optical quality neodymium, buffer ion‐codoped alkaline‐earth fluoride (Nd3+,B3+‐codoped MF2) laser ceramics.

Published: December 2019

AbstractBackgroundWhile people with intellectual disability (ID) face disparities relating to sexual and reproductive health (SRH) services, little is known about the role of family caregivers who assist women and girls with ID access SRH services. This scoping review examined the findings of studies to elucidate the role of family caregivers with regard to SRH for women and girls with ID.MethodWe used Arksey and O'Malley's six‐stage scoping framework, with Levac, Colquhoun and O'Brien's revisions, to evaluate identified sources. We searched three electronic databases, six ID journals and reference lists in full‐text articles. Inclusion criteria included (1) primary and secondary source research studies in peer‐reviewed journals; (2) published in English; (3) all research methodologies (i.e. qualitative, quantitative, mixed methods and systematic reviews or commentaries); (4) published between 2000 and 2016; and (5) studies from any country.ResultsThe search yielded 2062 studies; 57 articles met inclusion criteria. Most studies employed purposive, convenience or criterion sampling. Participants included people with ID, family caregivers, paid caregivers and health‐care professionals. Findings were summarised thematically: (1) menstruation and menopause; (2) vaccinations and preventive screenings; (3) supporting sexuality and healthy relationships; (4) coordinating with health‐care providers and (5) contraception and sterilisation.ConclusionsFindings from this scoping review underscore the need for more and better‐quality research, including how family caregivers assist women and girls with ID access perinatal and preventive SRH services and sexual abuse education. Family caregivers, women and girls with ID and health‐care providers need increased access to information about SRH.

Published: December 2019

AbstractThis study presents a citation‐based systematic literature review on banking sector performance, particularly in terms of profitability, productivity, and efficiency. Specifically, the study aims to identify the leading sources of knowledge in terms of the most influential journals, authors, and papers. The paper presents a content analysis of the 100 most cited papers. In total, 1996 peer‐review papers were found relevant in the Scopus database by using a comprehensive list of keywords. The results show that the Journal of Banking & Finance appears to be the leading journal in terms of publication count and citations. Based on total citations, Allen Berger is the most prolific author. The most cited paper is “Problem loans and cost efficiency in commercial banks” by Allan Berger and Robert DeYoung. The content analysis of the top 100 papers identifies five essential themes: determinants of efficiency, methodology, ownership, financial crises, and scale economies. In terms of estimation approaches, 74% of papers employed frontier analysis, which includes 34% parametric and 40% nonparametric methods, and remaining 26% have used financial ratio analysis. Additionally, stochastic frontier and data envelopment analysis are widely used in parametric and nonparametric methods, respectively. An intermediate approach is extensively adopted for the specification of inputs and outputs.
CORPORATE TAX AVOIDANCE: A LITERATURE REVIEW AND RESEARCH AGENDA
Authors: Wang Fangjun , Xu Shuolei , Sun Junqin , Cullinan Charles P. 
Published: December 2019

AbstractTax avoidance can range from reduction of the corporate tax burden by legitimate use of tax rules to violation of tax laws. In this paper, we endeavor to synthesize the major findings of tax avoidance research from the accounting and finance literatures over the past ten years. We consider theoretical developments and the related empirical findings about the interconnected issues of measuring tax avoidance, and the possible causes and outcomes of corporate tax avoidance. We present some ideas for further research to examine underexplored topics regarding tax avoidance.
Navigating the New Normal: Political Affinity and Multinationals’ Post‐Acquisition Performance
Authors: Hasija Dinesh , Liou Ru‐Shiun , Ellstrand Alan 
Published: December 2019

AbstractThe New Normal in the international business landscape reflects a world challenged by economic volatility and political hostilities. This suggests increased political risk, even for MNEs operating in developed markets. We use the legitimacy‐based view of political risk to examine how political affinity between host and home markets may contribute to an MNE’s post‐acquisition performance in a developed market. A high degree of political affinity signifies aligned national interests thus reducing legitimacy concerns faced by MNEs during post‐acquisition integration. Based on cross‐border M&A deals focused on U.S. targets completed by MNEs representing 45 countries between 2004 and 2012, we find that MNEs from countries with greater political affinity to the U.S. experience better post‐acquisition performance. We also investigate two country‐level factors that intensify the threat to legitimacy; the MNEs’ home market economic status and the presence of a financial crisis in the host market. Our findings indicate that political affinity mitigates risk for MNEs originated from emerging economies much more than for MNEs originated from developed economies, whereas a financial crisis reduces the benefit of political affinity.
Wisdom and value orientations: Just a projection of our own beliefs?
Authors: Glück Judith , Gussnig Bianca , Schrottenbacher Sarah M. 
Published: December 2019

AbstractObjectivesThis paper investigated which value orientations (1) people associate with wisdom and (2) are actually correlated with measures of wisdom. Conceptions of wisdom suggest benevolence and universalism as likely candidates.MethodIn Study 1, 160 university students reported their political orientation and completed a value survey for themselves and a very wise person; Study 2 used the same approach with a more diverse sample (N = 187). In Study 3, 170 participants completed a value survey and six measures of wisdom. In Study 4, 356 participants completed a wisdom measure and filled out a value survey for themselves and a very wise person.ResultsPeople consistently believed that wise individuals value benevolence, universalism, and self‐direction most; they also imagined wise individuals to be more universalistic but also more respectful of tradition than themselves. Several wisdom measures were uncorrelated with values; the positive correlations that were found were with benevolence, universalism, self‐direction, and respect for traditions.ConclusionsMost people believe that wise individuals are concerned about the well‐being of others, have respect for cultural, religious, and individual differences and traditions, and care deeply about self‐direction, fairness, and equality as fundamentals of human society. Whether these relationships are also found empirically depends on which measure of wisdom is used.

AbstractWhole blood carbonic anhydrase activity (CAa) is increased in patients with obstructive sleep apnea (OSA). Our study investigated the influence of positive airway pressure (PAP) or CA inhibitor acetazolamide (ACT) therapy on CAa, OSA and blood pressure. Thirty‐three OSA patients (21 hypertensive, body mass index (BMI) 37 ± 7 kg/m2 and apnea–hypopnea index (AHI) of 47 ± 31 events/hr) were followed‐up after PAP treatment (compliance, 4.7 ± 1.5 hr/day; duration, median 6 [IQR 6,6] months) (Cohort A). A second OSA Cohort (B) contained nine hypertensive patients (BMI, 29 ± 4 kg/m2; AHI, 39 ± 20 events/hr) with 2‐week treatment of ACT, PAP or ACT + PAP in an open crossover study. CAa was assessed at baseline and at the end of each treatment period. In Cohort A, baseline CAa was higher in hypertensive, compared with normotensive, patients (1,033 ± 204 versus 861 ± 201 units, p = .028). PAP treatment reduced systolic/diastolic blood pressure but not CAa (−9 ± 11/−5 ± 7 mmHg and −20 ± 289 units, p < .001, <.001 and .70). In Cohort B, blood pressure was reduced in both ACT‐treated groups (−10 ± 10/−5 ± 7 mmHg, p = .043 and .019; and −5 ± 5/−13 ± 13 mmHg, p < .001 and .009). AHI was reduced in both groups: ACT only, −17 ± 9 events/hr p = .001; and ACT + PAP, −39 ± 19 events/hr, p < .001. PAP did not change CAa (p = .98) but activity tended to decrease after ACT with or without PAP (p = .081 and .056). CAa is elevated in hypertensive OSA patients. Long‐term PAP reduced blood pressure without affecting CAa. ACT reduced blood pressure and CAa. Increased CAa may constitute a physiological characteristic in OSA, contributing to comorbid hypertension.

AbstractKeenjhar Lake, mega storage of drinking water for the residents of Karachi metropolis, agriculture cultivation and a well‐known recreational place, has been steadily contaminated. This study was aimed to understand the level of pollution and the reasons for a decrease in fish production over the past decade based on the available datasets. Focusing on some heavy metals such as Fe, Zn, Ni, Mn, Cu, Cr, Cd and Pb, beyond limit can cause of human health risk, here we provide a critical review of the previous studies conducted to findout reasonable solutions to cope with rapid environmental changes. A multivariate approach of principal component analysis (PCA) was applied to test the relationships among physicochemical parameters in relation to the heavy metals. The first component PCI revealed 88.09%, variability in the loaded dataset and PCII II 6.05% of the total variations. A cluster analysis was established to delineate heavy metal intensity in the corresponding years. Results indicated that since 2012, there has been a steady increase in heavy metal concentration, which can subsequently pose a significant threat to human health. Therefore, it is emphasized that carcinogenic health effects of such contamination on human health need to be investigated. However, over a decade datasets can solely fill knowledge gaps associated with framework conservation and management strategies.
Morphology of the vertebral centra in dolphins from the southwestern South Atlantic: A 3D morphometric approach and functional implications
Authors: Marchesi María C. , Boy Claudia C. , Dans Silvana L. , Mora Matías S. , González‐José Rolando 
Published: December 2019

AbstractIn dolphins, centrum shape is one of the features that allows determination of stable and flexible regions in the vertebral column. The Commerson's (Cephalorhynchus commersonii; n = 37), Peale's (Lagenorhynchus australis; n = 24), dusky (Lagenorhynchus obscurus; n = 29), and hourglass dolphins (Lagenorhynchus cruciger; n = 10) are closely related species inhabiting the Southern Hemisphere that have diverse prey and habitat preferences. We applied 3D geometric morphometrics to describe differences in centrum shape along the vertebral columns of these species, and hypothesize how these differences may affect swimming. On each column, we chose a maximum of eight vertebrae and digitized 18 landmarks on each centrum with a Microscribe G2X. We explored shape differences amongst regions employing principal components analyses and computing Mahalanobis distances. We describe differences in centrum shape in relation to functional regions and among species; and analyze shape changes in relation to particular biomechanical requirements. The species studied here may be partially sympatric in the Southern Hemisphere, but they have important differences in foraging ecology and habitat preferences that could be related to differences in centrum shape along the vertebral column.

AbstractBackgroundTechnical advances have improved the safety of cardiac implantable electronic device (CIED) insertion, but periprocedural complications persist. Despite ultrasound (US) guidance for vascular access being feasible and exhibiting shorter fluoroscopy times, it is not widely adopted for insertion of CIEDs. Thus, we studied the use of US for CIED insertion to (1) quantify the success rate of venous cannulation, (2) identify predictors of failed cannulation, and (3) quantify the rate of complications using US guidance.MethodsWe studied 166 consecutive patients who underwent US‐guided CIED implantation. Anatomic parameters of the axillary vein were measured. The primary outcome was success (group 1) or failure (group 2) to obtain vascular access utilizing US guidance. Secondary outcomes included pneumothorax and hematoma.ResultsSuccessful US‐guided cannulation occurred in 154 of 166 patients (93%). No patient had a pneumothorax. Hematoma occurred in 1 of 166 patients (0.01%). Group 2 exhibited higher male proportion at 11 of 12 (92%) compared with 94 of 154 (61%) in group 1 (P = .03), increased vein depth at 3.84 versus 2.85 cm (P = .003), more right‐sided implants (P = .03), higher weight at 104.6 versus 85.3 kg (P = .017), higher body mass index at 35.6 versus 29.2 kg/m2 (P = .049), and higher body surface area at 2.24 versus 1.99 m2 (P = .013). Other parameters were statistically nonsignificant. In multivariate analysis, vein depth remained significantly associated with failure.ConclusionUsing US guidance for CIED implantation is successful in the vast majority (93%) of patients. Rare cases of unsuccessful cannulation were associated with right‐sided implants and increased venous depth.
On a vector long wave‐short wave‐type model
Authors: Li Ruomeng , Geng Xianguo 
Published: December 2019

AbstractA new vector long wave‐short wave‐type model is proposed by resorting to the zero‐curvature equation. Based on the resulting Riccati equations related to the Lax pair and the gauge transformations between the Lax pairs, multifold Darboux transformations are constructed for the vector long wave‐short wave‐type model. This method is general and is suitable for constructing the Darboux transformations of other soliton equations, especially in the absence of symmetric conditions for Lax pairs. As an illustrative example of the application of the Darboux transformations, exact solutions of the two‐component long wave‐short wave‐type model are obtained, including solitons, breathers, and rogue waves of the first, second, third, and fourth orders. All the solutions derived by the Darboux transformations involve square roots of functions, which is not observed in the investigation of other nonlinear integrable equations. This model describes new nonlinear phenomena.
Bifurcations of autoresonant modes in oscillating systems with combined excitation
Authors: Sultanov Oskar A. 
Published: December 2019

AbstractA mathematical model describing the capture of nonlinear systems into the autoresonance by a combined parametric and external periodic slowly varying perturbation is considered. The autoresonance phenomenon is associated with solutions having an unboundedly growing amplitude and a limited phase mismatch. The paper investigates the behavior of such solutions when the parameters of the excitation take bifurcation values. In particular, the stability of different autoresonant modes is analyzed and the asymptotic approximations of autoresonant solutions on asymptotically long time intervals are proposed by a modified averaging method with using the constructed Lyapunov functions.
Lyme disease prevention: A content analysis of Canadian patient group and government websites
Authors: Journault Audrey‐Ann , Richard Lucie , Aenishaenslin Cécile 
Published: December 2019

AbstractThe quality of information presented on health‐related websites—in terms of comprehensiveness, accuracy and consistency—is a public health concern. To date, the consistency of information across Canadian websites devoted to Lyme disease (LD) prevention has not been evaluated. The first aim of this study was to describe the contents and recommendations of LD prevention websites provided by two types of Canadian organizations: government (n = 3) and patient groups (n = 3). A second objective was to analyse the level of convergence among these websites in terms of their prevention‐related content. Initial coding of the content resulted in information segments grouped into 114 subthemes related to nine overarching themes: tick habitat suitability, risk period, transmission, personal protection, peridomestic environmental management, tick identification and removal, early symptoms, testing and diagnosis and preventive treatment. Comparative content analyses were performed both within and between the content of websites of the two organization types. The themes most frequently addressed by both organization types were personal protection (20% of the prevention‐related content in patient group websites and 22% of the prevention‐related content in government websites), transmission (12% and 16%, respectively) and tick identification and removal (19% and 15%, respectively). Government websites’ information was generally convergent with that of patient group websites (four highly convergent themes, three moderately convergent and two divergent). Nevertheless, of particular concern were divergent messages and inaccurate information found on 11 subthemes out of 103. Examples included other possible modes of transmission and the ineffectiveness of DEET insect repellent. These results suggest the need for public health and health communications research on the issue of the quality of LD prevention information found on the Internet.
Projection-Based Continuous 3D Printing Process With the Grayscale Display Method
Authors: Wang Yancheng , Xue Dai , Mei Deqing 
Published: December 2019

Abstract
The printing resolution and scale of projection-based 3D printing are affected by the pixel size and projected light power. An effective and versatile method to print complex constructs with high resolution and large area is still required since light distribution in printing systems is generally non-uniform. Here, we propose a projection-based continuous 3D printing with the grayscale display method to serve as an effective and precise way to improve printing resolution and area. The light characterization results demonstrated that the power density presented a non-uniform distribution, and the power values are linear to the excitation power. After modifying the masks into grayscale according to the duty cycle of the digital micro-mirror device (DMD) display, projected light exhibited improved uniformity along with expected light power and uniform ratio. To validate this developed printing process, the grayscale continuous printing of mesh and hexahedron frame constructs enabled a remarkable increase in the printing area and alleviation of under/over curing. This work reveals significant progress in printing of constructs at larger area and higher resolution in projection-based continuous 3D printing under non-uniform light.
