Published: February 2017

AbstractPaper, as one of the most important information carriers, has contributed to the development and transmission of human civilization greatly. Meanwhile, a serious problem of environmental sustainable development caused by the production and utilization of paper has been resulted to modern society. Therefore, a simple and green route is urgently demanded to realize rewritable painting on paper. Herein, a simple route to rewritable painting on copy paper has been demonstrated by using eco-friendly ZnO nanoparticles (NPs) as fluorescent ink, and vinegar and soda that are frequently used in kitchen as erasing and neutralizing agents. Words or patterns written using the ZnO NPs as ink can be erased by vinegar vapour within five seconds, and after a neutralizing process in the ambient of soda vapour, the paper can be used for writing again. It is worth noting that the resolution and precision of the patterns produced via the above route degrade little after ten rewriting cycles, and the quality of the patterns produced using the ZnO NPs as ink fades little after being storage for several months, which promises the versatile potential applications of the rewriting route proposed in this paper.

Authors: Alvarenga Marco , da Rocha Thiago , Marchi Luis , Correia Leonardo 
Published: February 2017

The present study aims to describe the results of full-videoendoscopic surgery through the interlaminar route for central lumbar disc herniation in a series of 50 cases in Brazil.This is a retrospective single-center study. With the aim of describing safety, the present study reports the complication and revision rates. The clinical results were collected with the visual analogue scale (VAS) and with the Oswestry Disability Index (ODI) (a questionnaire to evaluate functional disability) at the preoperative visit and at 6 months postsurgery.The average surgical time was 20 minutes (range: 9–40 minutes), and 100% of the procedures were performed in an outpatient setting. The mean VAS scores improved from 9.4 to 1.1 (p < 0.001), and the mean ODI scores decreased from 69 to 9 points in the last follow-up (p < 0.001). There was 1 case (2%) with hernia recurrence, 1 case with intraoperative root injury (2%), and 2 cases (4%) that required lumbar fusion due to a preexisting instability. No infections were observed.The full-videoendoscopic surgery is a modern option for treating lumbar disc herniation. In the present study, we have observed that the use of this technique for the removal of fragments affecting the vertebral canal presented satisfactory clinical results, low complication rates, and that it has demonstrated its feasibility in an outpatient setting without prolonged hospitalization.

SignificanceSmad7 is a negative regulator of TGF-β signaling, a cytokine with anti-inflammatory properties. Although TGF-β was implicated in the development and function of dendritic cells (DCs), the in vivo role of Smad7 in DCs remains elusive. Here, we demonstrate that DC-specific Smad7 deletion affects the development of splenic CD8+CD103+DCs by regulating expression of the transcription factors Batf3 and IRF8. In addition, Smad7 directs DC function by regulating the expression of indoleamine 2,3-dioxygenase in response to IFN-γ signaling. Hence, absent Smad7 in DCs mediates resistance of mice to the development of autoimmunity via protective regulatory T-cell induction. These findings demonstrate that Smad7 expression governs splenic DC subset differentiation and affects tolerogenic DC function in vivo.
Reaction dynamics analysis of a reconstituted
Escherichia coli
protein translation system by computational modeling
Authors: Matsuura Tomoaki , Tanimura Naoki , Hosoda Kazufumi , Yomo Tetsuya , Shimizu Yoshihiro 
Published: February 2017

Significance
Biological systems are driven by multiple components and interactions that form a complex reaction network. We developed a method to analyze their dynamics by focusing on the component in temporal plateaus, or a quasi-stationary state (QSS). The analyses, using a computational model of a minimal in vitro protein synthesis system, showed that components in a QSS form clusters that grow over time. However, the growth is not in a linear fashion: The process involved collapse and regrowth of the formed clusters, where the collapse was closely related to the phase transition in the reaction network. These observations suggest that the studies focusing on the QSS might be useful for understanding of complex reaction dynamics.
MicroRNA-10a is crucial for endothelial response to different flow patterns via interaction of retinoid acid receptors and histone deacetylases

Published: February 2017

Significance
This study demonstrates that hormone receptor RARα plays a vital role in the selective activation of proinflammatory and anti-inflammatory signaling to modulate the miR-10a/GATA6/VCAM-1 cascade in endothelial cells in response to proatherogenic oscillatory shear stress (OS) vs. atheroprotective pulsatile shear stress (PS). HDAC-3/5/7 and RXRα are induced by OS and PS to serve as mechanosensitive “repressors” and “enhancers,” respectively, to associate with RARα to modulate its binding to RA-responsive element (RARE) to switch miR-10a expression. Our findings provide insight into the relationship between two different epigenetic factors (HDACs and miRs) and hormone receptors (RARα and RXRα) in the regulation of endothelial functions and elucidate new mechanisms of hemodynamic-based pathophysiology of the atherosclerotic vascular wall.
The Improbable Journeys of Epiphytic Plants Across The Andes: Historical Biogeography ofCycnoches(Catasetinae, Orchidaceae)

Published: February 2017

AbstractThe Andean uplift is one of the major orographic events in the New World and has impacted considerably the diversification of numerous Neotropical organisms. Despite its importance for biogeography, the specific role of mountain ranges as a dispersal barrier between South and Central American lowland plant lineages is still poorly understood. The swan orchids (Cycnoches) compriseca34 epiphytic species distributed in lowland and pre-montane forests of Central and South America. Here, we study the historical biogeography ofCycnochesto better understand the impact of the Andean uplift on the diversification of Neotropical lowland plant lineages. Using novel molecular sequences (five nuclear and plastid regions) and twelve biogeographic models with and without founder-event speciation, we infer that the most recent common ancestor ofCycnochesmay have originated in Amazoniaca5 Mya. The first colonization of Central America occurred from a direct migration event from Amazonia, and multiple bidirectional trans-Andean migrations between Amazonia and Central America took place subsequently. Notably, such biological exchange occurred well after major mountain building periods. The Andes have not acted as an impassable barrier for epiphytic lowland lineages such as orchids having a great potential for effortless dispersal because of the very light, anemochorous seeds.
Finite element analysis of flexible functionally graded beams with variable Poisson’s ratio
Authors: Pascon João Paulo 
Published: February 2017

Purpose
The purpose of this paper is to deal with large deformation analysis of plane beams composed of functionally graded (FG) elastic material with a variable Poisson’s ratio.

Design/methodology/approach
The material is assumed to be linear elastic, with a Poisson’s ratio varying according to a power law along the thickness direction. The finite element used is a plane beam of any-order of approximation along the axis, and with four transverse enrichment schemes, which can describe constant, linear, quadratic and cubic variation of the strain along the thickness direction. Regarding the constitutive law, five materials are adopted: two homogeneous limiting cases, and three intermediate FG cases. The effect of both finite element kinematics and distribution of Poisson’s ratio on the mechanical response of a cantilever is investigated.

Findings
In accordance with the scientific literature, the second scheme, in which the transverse strain is linearly variable, is sufficient for homogeneous long (or thin) beams under bending. However, for FG short (or moderate thick) beams, the third scheme, in which the transverse strain variation is quadratic, is needed for a reliable strain or stress distribution.

Originality/value
In the scientific literature, there are several studies regarding nonlinear analysis of functionally graded materials (FGMs) via finite elements, analysis of FGMs with constant Poisson’s ratio, and geometrically linear problems with gradually variable Poisson’s ratio. However, very few deal with finite element analysis of flexible beams with gradually variable Poisson’s ratio. In the present study, a reliable formulation for such beams is presented.

Authors: Dhuria Gaurav , Singh Rupinder , Batish Ajay 
Published: February 2017

Purpose
The purpose of this paper is to study the effect of ultrasonic machining process parameters on surface quality while machining titanium alloy Ti-6Al-4V.

Design/methodology/approach
Effect of cryogenic treatment (CT) of tool and work material was also explored in the study. Taguchi’s L18 orthogonal array was chosen for design of experiments and average surface roughness was measured.

Findings
Different modes of fracture were detected at work surface corresponding to varied input process parameters. Slurry grit size, power rating and tool material along with CT of work material were found to be the significant parameters affecting surface quality.

Originality/value
The results obtained have been modelled using artificial neural network approach.
Generational perceptions at work: in-group favoritism and out-group stereotypes
Authors: Weeks Kelly Pledger , Weeks Matthew , Long Nicolas 
Published: February 2017

Purpose
The purpose of this paper is to examine the relationship between stereotypes, in-group favoritism, and in-group bolstering effects across generations.

Design/methodology/approach
Based on the trends found in a qualitative study on generational stereotypes, questions on work ethic, work-life balance, and use of technology were administered to 255 participants identified as Millennials, Generation X, and Baby Boomers. Hypotheses predicted that with a strong stereotype, traditional in-group favoritism will not be found; however, an in-group bolstering effect will emerge. In the absence of a strong stereotype, traditional in-group favoritism is expected.

Findings
Generally, there was a strong stereotype that Baby Boomers are worse at technology than Generation X and Generation X is worse than Millennials. There was also a strong stereotype that Millennials do not do what it takes to get the job done as much as other generations. In the presence of these stereotypes, traditional in-group favoritism was not found, but in-groups bolstered themselves by rating themselves more favorably than other groups rated them. Although these findings did not hold for every item studied, there was moderate support for all three hypotheses.

Practical implications
As employees become aware of their biases, they can collaborate better with employees who are different than they are. Practical recommendations are suggested.

Originality/value
The paper applies theory of in-group favoritism to the perceptions of generational cohorts.
Cross-sectional variation of market efficiency
Authors: Jiang Jing 
Published: February 2017

Purpose
This paper aims to provide evidence that market efficiency varies greatly across individual stock, and across market exchanges.

Design/methodology/approach
Three approaches, partial adjustment model, Dimson beta model and variance ratio test, are used on a large sample of US stocks.

Findings
This paper finds prices are closer to random walk benchmarks (i.e. more efficient) for stocks with better liquidity provision, frequent trading, greater return volatility, higher prices, larger market capitalizations and smaller trade sizes. These findings suggest that liquidity stimulates arbitrage activity, which, in turn, enhances market efficiency. Market efficiency also varies with information environment. The results show that stocks with greater information-based trading exhibit higher level of efficiency. Finally, market structure influences market efficiency. New York Stock Exchange stocks achieve higher level of efficiency than NASDAQ stocks do. The empirical results are robust and not driven by differences in stock attributes between the two markets.

Research limitations/implications
Overall, these results indicate that liquidity provision, stock attributes and market structure exert a significant impact on the realization of market efficiency.

Practical implications
In addition, this paper is also relevant to both stock exchanges facing increased competition and to market regulators.

Originality/value
Prior studies offer little evidence on the speed at which new information is impounded into the price. There is also limited evidence regarding how liquidity provision and market structure affect market efficiency. Using a transformation of the speed of price adjustment and other measurements as proxies for individual stock efficiency, this study may shed further lights on our understanding of market efficiency.
Corporate governance and executive perquisites
Authors: Andrews Angela , Linn Scott , Yi Han 
Published: February 2017

Purpose
The purpose of this paper is to examine the relation between executive perquisite consumption and indicators of corporate governance after the Securities and Exchange Commission (SEC) expanded the disclosure requirements related to perquisites.

Design/methodology/approach
This study uses ordinary least squares and Tobit regressions to examine the dollar value of perquisites consumed, the number of perquisites consumed and the types of perquisites consumed.

Findings
The analysis shows that firms with weak corporate governance are more likely to award perquisites to executives. Firms characterized as being more prone to the presence of agency problems are associated with greater levels of perquisite consumption. Finally, there is evidence that not all perquisite consumptions can be attributed to an agency problem. Efficiently operating firms are associated with greater levels of perquisite consumption as are larger firms.

Research limitations/implications
The authors examine firms in the period immediately after the SEC initiated the expanded disclosures. This may limit the generalizability of the results to other exchange-listed firms that changed their perquisite policy as a result of the rule change.

Originality/value
The paper extends the literature on corporate governance and mandatory corporate disclosure by investigating the association between corporate governance characteristics and perquisite consumption. This paper examines this relation immediately after the SEC expanded the disclosures surrounding perquisites to provide the public with more transparent disclosures.
‘Post‐Third‐World City' or Neoliberal ‘City of Exception'? Rio de Janeiro in the Olympic Era
Authors: Aaron Richmond Matthew , Garmany Jeff 
Published: February 2017

AbstractThis article considers processes of urban development within the context of mega‐event preparations in Rio de Janeiro. We begin with a brief overview of these development processes, highlighting their connections to political and economic change in recent years. Proponents of these mega‐event‐led initiatives argue that Rio is undergoing a period of inclusive growth and integration: a perspective we call here a ‘post‐Third‐World city' narrative of urban renewal. Critics, however, contend that urban officials are harnessing mega‐events (e.g. the 2014 World Cup and the 2016 Olympic Games) to push forward a neoliberal agenda of socially unjust policies benefiting the interests of capital and marginalizing the city's poor and especially its favelas (i.e. the ‘city‐of‐exception' thesis). In this article we explore the insights of these two perspectives and consider why they have grown popular in recent years. Though we side generally with the city‐of‐exception thesis, we argue that important geographic and historical particularities must also be accounted for. Without carefully situating analytical perspectives empirically—in particular, cases in which theoretical models are drawn from European and North American contexts—urban researchers risk concealing more than they reveal in analyses of rapidly developing countries like Brazil.
Sexual Dimorphism of the First Rib: A Comparative Approach Using Metric and Geometric Morphometric Analyses
Authors: Lynch Jeffrey James , Cross Peter , Heaton Vivienne 
Published: February 2017

AbstractThis research investigated the sexual dimorphism of the first human rib using geometric morphometric and metric approaches on a sample of 285 specimens containing European Americans and African Americans from the Hamann‐Todd collection. Metric measurements were investigated for sexual dimorphism and ancestral differences using univariate statistics. Four type II landmarks and 40 sliding semi‐landmarks were placed outlining the dorsal and ventral curvatures of the ribs. Landmark data were processed using Generalized Procrustes Analyses with Procrustes distance sliding, and the subsequent coordinates were investigated for sexual dimorphism and ancestral differences using Procrustes ANOVAs. Both geometric morphometric and metric data were analyzed using cross‐validated discriminant function analyses to test the hypothesis that variables from both approaches can be combined to increase sex classification rate. European Americans had sex correctly classified as high as 88.05% and African Americans as high as 70.86% using a combination of metric and geometric morphometric variables.
Application of the Stephan et al. Chest Radiograph Comparison Method to Decomposed Human Remains
Authors: Isa Mariyam I. , Hefner Joseph T. , Markey Michael A. 
Published: February 2017

AbstractThis manuscript describes the use of comparative radiography of the chest to facilitate positive identification of human remains in advanced stages of decomposition. The method reported by Stephan et al. for positive identification of dry, disarticulated skeletal elements was used on semifleshed, decomposing remains. Positive identification was established through multiple points of concordance observed in radiographs of the left and right clavicles and the C5‐T1 vertebrae. This case study demonstrates the applicability of the Stephan et al.'s method in cases involving decomposing remains.

Published: February 2017

SummaryThe genetic basis of haemophagocytic lymphohistiocytosis (HLH) has not been elucidated in 10% of affected patients. In this study, we report four HLH episodes in three patients with HAX1 gene mutations. We screened the mutations associated with congenital neutropenia (CN) because the neutropenia persisted following HLH treatment. There were homozygous HAX1 mutations detected in all patients. This is the first case series of patients with CN caused by HAX1 mutation who presented with HLH. We hypothesize that severe neutropenia persists after an HLH episode in children without HLH mutations (especially infants) because these patients have CN caused by HAX1 mutations.

Published: February 2017

AbstractThe Podolia region is located along the western border of the Eastern European Craton, which is also known as Ukrainian Shield. From the Ordovician to the Miocene, this area formed part of an epicontinental basin system. In order to investigate the effects of orogenic cycles occurring along the plate margin, a multi‐disciplinary approach was used in this study. Paleotemperature analysis and low‐temperature thermochronometry were combined with stratigraphic data to obtain a burial model for the Paleozoic succession exposed in the study area. Maximum burial for Silurian and Devonian rocks occurred during the Devonian and Early Carboniferous at depths of 4–5 km, as constrained by vitrinite reflectance and illite content in mixed illite‐smectite layers. Thermochronometric data indicate that exhumation through the 45–120 °C temperature range took place between the Late Triassic and the Early Jurassic, and that no significant burial occurred afterwards (temperatures characterising the stratigraphically lowermost units remaining below ca. 60 °C). These results point to a major exhumation event coeval with the Cimmerian orogenesis, which took place a few hundreds of kilometres away from the study area. On the other hand, no significant effect of the Alpine orogenesis was recorded, although the collisional front was located <100 km from the Podolia region. This work shows how paleothermal and thermochronometric analyses can be successfully integrated with stratigraphic data to reconstruct the burial history, and how the burial history of a basin located on a plate margin can, in some cases, be independent from the distance of the margin from the collisional fronts.
