Published: September 2015

AbstractTo solve a long-standing problem of condensed matter physics with determining a proper description of the thermodynamic evolution of the time scale of molecular dynamics near the glass transition, we have extended the well-known Adam-Gibbs model to describe the temperature-volume dependence of structural relaxation times, τα(T, V). We also employ the thermodynamic scaling idea reflected in the density scaling power law, τα = f(T−1V−γ), recently acknowledged as a valid unifying concept in the glass transition physics, to differentiate between physically relevant and irrelevant attempts at formulating the temperature-volume representations of the Adam-Gibbs model. As a consequence, we determine a straightforward relation between the structural relaxation time τα and the configurational entropy SC, giving evidence that also SC(T, V) = g(T−1V−γ) with the exponent γ that enables to scale τα(T, V). This important findings have meaningful implications for the connection between thermodynamics and molecular dynamics near the glass transition, because it implies that τα can be scaled with SC.
Emotional attention capture by facial expressions
Authors: Sawada Reiko , Sato Wataru 
Published: September 2015

AbstractPrevious studies have shown that emotional facial expressions capture visual attention. However, it has been unclear whether attentional modulation is attributable to their emotional significance or to their visual features. We investigated this issue using a spatial cueing paradigm in which non-predictive cues were peripherally presented before the target was presented in either the same (valid trial) or the opposite (invalid trial) location. The target was an open dot and the cues were photographs of normal emotional facial expressions of anger and happiness, their anti-expressions and neutral expressions. Anti-expressions contained the amount of visual changes equivalent to normal emotional expressions compared with neutral expressions, but they were usually perceived as emotionally neutral. The participants were asked to localize the target as soon as possible. After the cueing task, they evaluated their subjective emotional experiences to the cue stimuli. Compared with anti-expressions, the normal emotional expressions decreased and increased the reaction times (RTs) in the valid and invalid trials, respectively. Shorter RTs in the valid trials and longer RTs in the invalid trials were related to higher subjective arousal ratings. These results suggest that emotional facial expressions accelerate attentional engagement and prolong attentional disengagement due to their emotional significance.

AbstractA Ta/TaOx/Pt stacked capacitor-like device for resistive switching was fabricated and examined. The tested device demonstrated stable resistive switching characteristics including uniform distribution of resistive switching operational parameters, highly promising endurance and retention properties. To reveal the resistive switching mechanism of the device, micro structure analysis using high-resolution transmission electron microscope (HR-TEM) was performed. From the observation results, two different phases of Ta-metal clusters of cubic α-Ta and tetragonal β-Ta were founded in the amorphous TaOx mother-matrix after the device was switched from high resistance state (HRS) to low resistance state (LRS) by externally applied voltage bias. The observed Ta metal clusters unveiled the origin of the electric conduction paths in the TaOx thin film at the LRS.
Investigation of diffusion length distribution on polycrystalline silicon wafers via photoluminescence methods
Authors: Lou Shishu , Zhu Huishi , Hu Shaoxu , Zhao Chunhua , Han Peide 
Published: September 2015

AbstractCharacterization of the diffusion length of solar cells in space has been widely studied using various methods, but few studies have focused on a fast, simple way to obtain the quantified diffusion length distribution on a silicon wafer. In this work, we present two different facile methods of doing this by fitting photoluminescence images taken in two different wavelength ranges or from different sides. These methods, which are based on measuring the ratio of two photoluminescence images, yield absolute values of the diffusion length and are less sensitive to the inhomogeneity of the incident laser beam. A theoretical simulation and experimental demonstration of this method are presented. The diffusion length distributions on a polycrystalline silicon wafer obtained by the two methods show good agreement.

AbstractEffect of a polarized P(VDF-TrFE) ferroelectric polymer gating on AlGaN/GaN metal-oxide-semiconductor high-electron-mobility transistors (MOS-HEMTs) was investigated. The P(VDF-TrFE) gating in the source/drain access regions of AlGaN/GaN MOS-HEMTs was positively polarized (i.e., partially positively charged hydrogen were aligned to the AlGaN surface) by an applied electric field, resulting in a shift-down of the conduction band at the AlGaN/GaN interface. This increases the 2-dimensional electron gas (2-DEG) density in the source/drain access region of the AlGaN/GaN heterostructure and thereby reduces the source/drain series resistance. Detailed material characterization of the P(VDF-TrFE) ferroelectric film was also carried out using the atomic force microscopy (AFM), X-ray Diffraction (XRD) and ferroelectric hysteresis loop measurement.
Robust half-metallicity and topological aspects in two-dimensional Cu-TPyB
Authors: Zhang Xiaoming , Zhao Mingwen 
Published: September 2015

AbstractHalf-metallicity due to the coexistence of metallic nature for one spin component and insulating nature for the other is a base of spintronics devices, but was only achieved in few materials. From first-principles calculations, we demonstrate that a recently-synthesized two-dimensional organometallic framework of 1,3,5-tris(pyridyl)benzene and Cu atoms (Cu-TPyB) has robust half-metallicity. High electron velocity in one spin channel at Dirac point and a relatively large band gap in the other make the material meeting the demand of filtering the current into a single spin component. Moreover, spin-orbit coupling induces topologically nontrivial band gaps in the vicinity of the Fermi level, which are implementable for achieving quantum anomalous Hall effect in a low temperature range (<8 K).

Published: September 2015

AbstractThe development of multi-electrode array platforms for large scale recording of neurons is at the forefront of neuro-engineering research efforts. Recently we demonstrated, at the proof-of-concept level, a breakthrough neuron-microelectrode interface in which cultured Aplysia neurons tightly engulf gold mushroom-shaped microelectrodes (gMμEs). While maintaining their extracellular position, the gMμEs record synaptic- and action-potentials with characteristic features of intracellular recordings. Here we examined the feasibility of using gMμEs for intracellular recordings from mammalian neurons. To that end we experimentally examined the innate size limits of cultured rat hippocampal neurons to engulf gMμEs and measured the width of the “extracellular” cleft formed between the neurons and the gold surface. Using the experimental results we next analyzed the expected range of gMμEs-neuron electrical coupling coefficients. We estimated that sufficient electrical coupling levels to record attenuated synaptic- and action-potentials can be reached using the gMμE-neuron configuration. The definition of the engulfment limits of the gMμEs caps diameter at ≤2–2.5 μm and the estimated electrical coupling coefficients from the simulations pave the way for rational development and application of the gMμE based concept for in-cell recordings from mammalian neurons.

AbstractMoyamoya disease leads to the formation of stenosis in the cerebrovasculature. A superficial temporal artery to middle cerebral artery (STA-MCA) bypass is an effective treatment for the disease, yet it is usually associated with postoperative cerebral hyperperfusion syndrome (CHS). This study aimed to evaluate cerebral hemodynamic changes immediately after surgery and assess whether a semiquantitative analysis of an intraoperative magnetic resonance perfusion-weighted image (PWI) is useful for predicting postoperative CHS. Fourteen patients who underwent the STA-MCA bypass surgery were included in this study. An atlas-based registration method was employed for studying hemodynamics in different cerebral regions. Pre- versus intraoperative and group-wise comparisons were conducted to evaluate the hemodynamic changes. A postoperative increase in relative cerebral blood flow (CBF) at the terminal MCA territory (P = 0.035) and drop in relative mean-time-transit at the central MCA territory (P = 0.012) were observed in all patients. However, a significant raise in the increasing ratio of relative-CBF at the terminal MCA territory was only found in CHS patients (P = 0.023). The cerebrovascular changes of the patients after revascularization treatment were confirmed. Intraoperative PWI might be helpful in predicting the change in relative-CBF at MCA terminal territory which might indicate a risk of CHS.
Political extremism, group membership and personality traits: who accepts violence? / Extremismo político, pertenencia al grupo y rasgos de personalidad: ¿Quién acepta la violencia?
Authors: Besta Tomasz , Szulc Marcin , Jaśkiewicz Michał 
Published: September 2015

Identity fusion theory proposed that fused individuals have a visceral feeling of oneness with the group and this leads them to engage in radical, violent pro-group behaviours. Other approaches to group extremism link acceptance of violence to right-wing authoritarianism (RWA) and social dominance orientation (SDO). We extended previous research on fusion in three ways. First, by exploring if identity fusion is a significant predictor of the willingness to fight for a group, when controlling for group identification, left-wing authoritarianism (LWA), RWA and SDO. Secondly, we controlled for a membership in a group known for radical action directed at out-groups, namely football hooligans. Finally, we added a second outcome variable, which is the acceptance of violent change of the current social system. The participants were self-described football hooligans ( N = 24) and undergraduate students ( N = 155). Regression analyses revealed that the strongest predictor of willingness to defend in-group was identity fusion, with RWA and group identification significant as well. RWA and LWA emerged as the strongest predictors of acceptance of violent change. The effect of group membership wasn’t significant.
Risk Screening of Arapaima, a New Species Proposed for Aquaculture in Florida
Authors: Hill Jeffrey E. , Lawson Katelyn M. 
Published: September 2015

Abstract
Agencies have a growing range of options for risk assessment of nonnative species varying from comprehensive assessments to rapid risk screens. Risk screens identify high-risk and low-risk species and those where more evaluation is warranted. Despite development and testing of risk-screening methods, there is little information in the literature regarding their implementation in management decisions. We used a screening tool, the Fish Invasiveness Screening Kit (FISK), coupled with a detailed literature review to evaluate the risks of the genus Arapaima across Florida, where there is growing interest in its culture as a food fish. We found a medium risk of invasiveness overall, the greatest risk being to subtropical south Florida due to the low cold tolerance of Arapaima that it would experience further north. Ultimately the agency determined that a combination of literature review and the risk screen was sufficient to inform their decision making and that current conditional species regulations provided adequate risk mitigation to allow culture. The agency saved time and money by developing background information and a preliminary estimate of risk prior to engaging in comprehensive assessment. Flexibility allows agencies to tailor their risk assessment and management processes to different risk environments and to better inform decision making.

Human capital and professional network effects on women’s odds of corporate board directorships
Authors: Hodigere Renuka , Bilimoria Diana 
Published: September 2015

Purpose– The purpose of this study is to examine the importance of human capital and professional networks for women’s and men’s appointment to the boards of directors of public companies. The study provides an in-depth analysis of how human capital and professional networks contribute to women’s as compared with men’s odds of corporate board membership.Design/methodology/approach– The study analyzes the human capital and professional networks of 494 male and female corporate outside (non-executive) directors appointed between 2005 and 2010 to the boards of US public companies listed in the Standard & Poor’s 500 index. Human capital was measured as director age, education and professional experience (function and role). Professional network variables measured included composition of professional network, network centrality, constraint and cohesion.Findings– The study’s findings reveal that the characteristics that impact the appointment of women as outside directors to public company boards differ from those of men. Relative to men, certain professions such as government relations and education improve the odds of appointment of women to corporate boards, while age lowers women’s odds. The number of network ties and the degree of network cohesion were also significant in predicting the likelihood of female board appointment to public corporations relative to men’s odds. The final model was able to predict female board membership correctly only in 28 per cent of the cases, while male board membership was predicted in 89 per cent of the cases, suggesting that factors other than human capital and professional networks (e.g. their gender) impact women’s appointment to corporate boards.Originality/value– To the authors ' knowledge, this study is the first to comprehensively examine the professional network components of female and male directors along with their human capital in the analysis of their prospects for board appointment. The conceptualization of professional networks as well the depth of quantitative analysis of the network components of the study advance the extant literature on the composition of corporate boards.
Researching Asian consumer culture in the global marketplace
Authors: Seo Yuri , Fam Kim-Shyan 
Published: September 2015

Purpose
– In this editorial viewpoint for the special issue, the authors identify a need to deepen our understanding of the important role that Asian consumer culture plays in the global marketplace of the twenty-first century.

Design/methodology/approach
– This editorial article discusses the emergence of Asian consumer culture, offers an integrative summary of the special issue and develops several key directions for future research.

Findings
– The authors observe that Asian consumer culture is not a coherent knowledge tradition that can be described merely as “collectivist” or “Confucianist” in nature. Rather, it is better understood as the confluence of cultural traditions that are characterized by inner differentiation and complexity, various transformations and mutual influences in the Asian region and beyond.

Research limitations/implications
– Although Asia’s economic growth has received much recent attention, extant theory regarding Asian consumer culture is still in its infancy. The authors highlight important developments in this area that show the path for future work.

Originality/value
– The authors make three contributions to the emerging scholarly interest in Asian consumer culture. First, the authors respond to recent calls to increase the use of qualitative methods in Asian contexts. Second, the authors draw attention to the cultural complexities and mutual influences that characterize contemporary Asian consumer cultures, and subcultures in the Asian region and beyond, through the selection of articles for this special issue. Finally, the authors draw the threads together to provide directions for future research in this area.
The discontinuous evolution of women’s fashion in China
Authors: Ucok Hughes Mine , Eckhardt Giana , Kaigler-Walker Karen , Gilbert Zelda 
Published: September 2015

Purpose– The aim of this study is to provide an understanding of urban Chinese women’s fashion consumption practices in light of major recent socio-historical events and to demonstrate that changes in fashion are not necessarily continuous, but rather can be discontinuous in the wake of radical disturbances.Design/methodology/approach– A phenomenological study was conducted that included group interviews with Chinese women belonging to three age cohorts who experienced different radical changes in recent Chinese history.Findings– This study provides insights into how fashion develops when radical economic and social shifts result in a discontinuous rather than continuous fashion evolution. In China, it can be seen that these radical ideological shifts had discontinuous effects on notions of beauty and how identity is expressed through fashion. The changes seen in the past 60 years or so – from the advent of communism in 1949 until now – cannot be explained by theories of imitation and distinction alone. The changes are also anchored to key socio-historic events, and were not necessarily an outgrowth of the period before, or class-based practices, but rather a response to social upheavals.Originality/value– This study provides a nuanced understanding of how tumultuous socio-cultural events affect how fashion is experienced in China, which allows us to contribute to the growing understanding of Chinese consumer culture, and demonstrate that the understanding of how fashion evolves needs to accommodate the upheavals in society over the past sixty years.

AbstractPsoriasis is a common inflammatory disease that has a severe impact on quality of life. There is lack of data regarding epidemiological and clinical features of psoriasis patients in Turkey, a country with a population of 76 million. The aim of this study was to define the demographic and clinical characteristics, quality of life and treatment patterns of psoriasis patients in Turkey. A cross‐sectional observational study was conducted at 40 centers, chosen from geographically diverse locations in Turkey. Patients diagnosed with psoriasis were assessed by investigators who were specialists of dermatology using standardized study questionnaire forms. Dermatology Life Quality Index (DLQI) and EuroQol‐5 dimension (EQ‐5D) forms were also filled out by each patient. 3971 psoriasis patients were included in this study. 24.2% of plaque psoriasis patients had moderate to severe psoriasis (Psoriasis Area and Severity Index, ≥10). Mean DLQI was 7.03 ± 6.02; quality of life was moderately, severely or very severely affected in 49.2% of patients. The most severely affected component of EQ‐5D was anxiety/depression. Among all patients, 22.9% were not receiving any treatment, 39.8% were receiving only topical treatment, 11.5% were on phototherapy, 26.1%, were taking conventional systemic agents and 4.1% were on a biologic treatment. 31.3% of psoriasis patients with moderate to severe disease were treated with only topical agents and only 30.5% of moderate to severe psoriasis patients were receiving systemic therapy. Moderate to severe psoriasis has a considerable impact on quality of life. Treatment in Turkey of patients with moderate to severe psoriasis is insufficient.

AbstractPatients with psoriasis, in particular those with severe disease, have an increased risk of cardiovascular (CV) events compared with the general population. The aim of the present study is to determine whether correlation between asymmetric dimethylarginine (ADMA) and osteoprotegerin (OPG), two biomarkers associated with CV disease, and disease severity may exist in patients with moderate‐to‐severe psoriasis. We also aimed to establish if baseline serum levels of these two biomarkers could correlate with the degree of change in the clinical parameters of disease severity following the use of anti‐tumor necrosis factor (TNF)‐α therapy in these patients. This was a prospective study on a series of consecutive non‐diabetic patients with moderate‐to‐severe psoriasis who completed 6 months of therapy with anti‐TNF‐α‐adalimumab. Patients with kidney disease, hypertension or body mass index of 35 kg/m2 or more were excluded. Metabolic and clinical evaluation was performed immediately prior to the onset of treatment and at month 6. Twenty‐nine patients were assessed. Unlike OPG, a significant positive correlation between ADMA and resistin serum levels was found at the onset of adalimumab and also after 6 months of biologic therapy. We also observed a positive correlation between the percent of body surface area affected (BSA) and ADMA levels obtained before the onset of adalimumab and a negative correlation between baseline ADMA levels and a 6‐month BSA change compared with baseline results. In patients with moderate‐to‐severe psoriasis, ADMA levels correlate with clinical markers of disease severity.
