Purpose. China has a high prevalence of smoking, but the characteristics of social smoking in Chinese college students have not been investigated. We examined the pattern of social smoking and explored the association between social smoking and personal cessation efforts and mental health factors among Chinese male college students. Design. Study design was a cross-sectional survey. Setting. P. R. China was the setting of the study. Subjects. Participants were a random sample of 1327 male college students. Measures. All participants completed a self-administered questionnaire that examined their smoking behaviors and a group of specific mental health factors (loneliness, self-harm, suicide, depression, and anxiety). Analysis. Analysis was conducted using descriptive statistics, χ2 analysis, and multivariate logistic regression. Results. Of a total of 207 current smokers, 102 (49.3%) were identified as social smokers. Compared with nonsmokers, social smokers had increased risks for depression (odds ratio, 1.74; 95% confidence interval, 1.15–2.65). Among daily smokers, social smokers were less likely to have an intention to quit smoking than nonsocial smokers (odds ratio, .08; 95% confidence interval, .01–.57). Conclusion. This study reveals unique psychologic characteristics related to social smoking. College students are a particular group of interest because unhealthy behaviors initiated during adolescence may continue through adulthood. Our findings provide evidence for future tobacco control intervention among this population.
Role of the Public Engagement in the Reconstruction and Revival of the Distressed Urban Textures: Case Study of District 4 in Isfahan, Iran
Authors: Momeni Mehdi 
Published: November 2015

<p class="zhengwen"><span lang="EN-GB">Old textures suffer deficiencies in terms of answering the needs of the today’s life due to old age and the resultant weariness and destruction and even the lack of urban facilities and equipment. When the urban life in part of a city becomes stagnant and no efforts are made to regain its boom. The urban texture in that area will be exposed to wearing out. The goal of this study is to review the existing drawbacks and bottlenecks in the process of the revival of the distressed texture of one of the neighborhoods located in District 4, Isfahan, called Kerdabad. The research method is applied in nature and follows a descriptive analytic approach. The findings of the research covers issues such as incompatible applications, resulting in the fact that 80 percent of respondents attribute their dissatisfaction from the environmental conditions of the neighborhood to workshop areas and agricultural fields in the margin of their neighborhood which in turn has resulted in slum life problems in the neighborhood and formation of an inconsistent social context in which 63 percent of the people are dissatisfied of these conditions. While 70 percent of the respondents express their willingness to refurbish their houses, only 73 percent of the respondents attribute proximity to their workplace as the main reason why they prefer to stay in the neighborhood and 89 inhabitants are not well satisfied with the urban services delivered. </span></p>

Published: November 2015

<p>Developing states, following the theory of “the survival of the fittest”, are severely in need of building up their electronic commerce for their economic survival on the globe. Beside other challenges, developing states are lagging behind in terms of technology readiness (TR). Another leading factor, particularly within the practicing Muslim communities, could be the impact of religiosity that has been unanimously found playing an immense role in buyers’ buying attitude, judgment of product price and quality. Having an immense influence, it affects both intra-personally and interpersonally. Furthermore, religiosity shapes consumers’ mind-set, learning and life style and is also considered as one of the significant factors with regards to hi-tech innovations adoption. This paper puts light on the relevant and valuable perspectives: technology readiness, religiosity and diffusion of electronic commerce, in the perspective of Muslim majority developing countries. While contributing to the field of knowledge, the study highlights the importance of technology readiness and trust in the diffusion process of electronic commerce. Looking into the moderating effect of religiosity in this regard, it underlines the unique features (completeness, universality, ever-greenness and applicability) of Islam including the moderate approach of Islam, toward technologies including e-commerce, thus boosting up electronic commerce trade. While, possessing the practical, educational and theological implications, the study will be helpful to all the stakeholders including; prospective consumers, governmental concerned authorities and e-commerce global community.</p><p class="Default"> </p>

L’article se propose d’examiner comment l’Université de São Paulo s’efforce de répondre aux défis actuels posés par la formation de formateurs dans les arts de la scène, aussi bien dans l’univers scolaire que dans la sphère de l’action culturelle et artistique. Nous partons du principe que de profondes mutations traversent la scène contemporaine – dilution des frontières entre les arts, présence de la dimension performative, usage de matériaux variés comme point de départ des processus de création, entre autres –, révélant de nouveaux besoins et ouvrant de nouvelles perspectives pour la formation de ces professionnels. L’importance d’une expérience artistique forte, la compréhension du rôle de la recherche, la réalisation d’une praxis qui puisse dépasser la dichotomie entre théorie et pratique sont invoquées comme des aspects particulièrement prometteurs dans cette formation professionnelle. On reconnaît aussi dans quelle mesure les recherches des artistes contemporains contribuent à la reformulation des principes directeurs relatifs aux interventions de formation.
Real‐time volcano monitoring using GNSS single‐frequency receivers

Published: November 2015

AbstractWe present a real‐time volcano monitoring strategy that uses the Global Navigation Satellite System (GNSS), and we examine the performance of the strategy by processing simulated and real data and comparing the results with published solutions. The cost of implementing the strategy is reduced greatly by using single‐frequency GNSS receivers except for one dual‐frequency receiver that serves as a base receiver. Positions of the single‐frequency receivers are computed relative to the base receiver on an epoch‐by‐epoch basis using the high‐rate double‐difference (DD) GNSS technique, while the position of the base station is fixed to the values obtained with a deferred‐time precise point positioning technique and updated on a regular basis. Since the performance of the single‐frequency high‐rate DD technique depends on the conditions of the ionosphere over the monitoring area, the ionospheric total electron content is monitored using the dual‐frequency data from the base receiver. The surface deformation obtained with the high‐rate DD technique is eventually processed by a real‐time inversion filter based on the Mogi point source model. The performance of the real‐time volcano monitoring strategy is assessed through a set of tests and case studies, in which the data recorded during the 2007 eruption of Kilauea and the 2005 eruption of Augustine are processed in a simulated real‐time mode. The case studies show that the displacement time series obtained with the strategy seem to agree with those obtained with deferred‐time, dual‐frequency approaches at the level of 10–15 mm. Differences in the estimated volume change of the Mogi source between the real‐time inversion filter and previously reported works were in the range of 11 to 13% of the maximum volume changes of the cases examined.
Effects of lateral variations in megaregolith thickness on predicted lunar seismic signals

Published: November 2015

AbstractWe use a modified phonon synthetic seismogram method to investigate the effects of laterally varying megaregolith thickness on the propagation of seismic energy and on the resulting seismic signals recorded at various epicentral distances from the source. We show that receivers located in large impact structures, with thin crust and thinner megaregolith, can record seismic signals that are less affected by high levels of scattering. In particular, receivers located away from the basin edge by a distance greater than or equal to the thickness of the surrounding megaregolith can record seismograms in which secondary arrivals containing important information about interior structure can be more readily identified. Seismic sources located beneath the near‐surface scattering layer, such as deep lunar quakes, are also advantageous because the resulting seismograms are less affected by high levels of scattering than those from sources within the scattering layer or surface impacts.
Regolith stratigraphy at the Chang'E‐3 landing site as seen by lunar penetrating radar
Authors: Fa Wenzhe , Zhu Meng‐Hua , Liu Tiantian , Plescia Jeffrey B. 
Published: November 2015

AbstractThe Chang'E‐3 lunar penetrating radar (LPR) observations at 500 MHz reveal four major stratigraphic zones from the surface to a depth of ~20 m along the survey line: a layered reworked zone (<1 m), an ejecta layer (~2–6 m), a paleoregolith layer (~4–11 m), and the underlying mare basalts. The reworked zone has two to five distinct layers and consists of surface regolith. The paleoregolith buried by the ejecta from a 500 m crater is relatively homogenous and contains only a few rocks. Population of buried rocks increases with depth to ~2 m at first, and then decreases with depth, representing a balance between initial deposition of the ejecta and later turnover of the regolith. Combining with the surface age, the LPR observations indicate a mean accumulation rate of about 5–10 m/Gyr for the surface regolith, which is at least 4–8 times larger than previous estimation.

AbstractDie enantiospezifische Kontrolle der chemischen Reaktionen mittels chiraler Medien, z. B. chiraler mesoporöser Materialien, ist eine große Herausforderung. Hier beschreiben wir eine neue und effektive Syntheseroute für enantioselektive nanoporöse Kohlenstoffe aus chiralen ionischen Flüssigkeiten (CIFs). CIFs aus Phenylalanin (CIF(Phe)) werden als Vorstufen für die Karbonisierung von chiralen mesoporösen Kohlenstoffen verwendet. Wir wenden Zirkulardichroismus‐Spektroskopie, isotherme Titrationskalorimetrie (ITK) und Chronoamperometrie an, um die chirale Natur der mesoporösen Kohlenstoffe zu zeigen. Die vorgestellte Herangehensweise ist von großer Bedeutung für die Entwicklung neuartiger chiraler poröser Materialien im Bereich der enantioselektiven Chemie. Außerdem trägt sie wesentlich zu unserem Verständnis der Struktur und der Natur von chiralen nanoporösen Materialien und Oberflächen bei.

Published: November 2015

Abstract1H‐detection can greatly improve spectral sensitivity in biological solid‐state NMR (ssNMR), thus allowing the study of larger and more complex proteins. However, the general requirement to perdeuterate proteins critically curtails the potential of 1H‐detection by the loss of aliphatic side‐chain protons, which are important probes for protein structure and function. Introduced herein is a labelling scheme for 1H‐detected ssNMR, and it gives high quality spectra for both side‐chain and backbone protons, and allows quantitative assignments and aids in probing interresidual contacts. Excellent 1H resolution in membrane proteins is obtained, the topology and dynamics of an ion channel were studied. This labelling scheme will open new avenues for the study of challenging proteins by ssNMR.

Published: November 2015

AbstractThe first rhodium‐catalyzed intramolecular hetero‐[5+2] cycloaddition reaction of vinyl aziridines and alkenes was realized, wherein both internal and terminal alkenes were applicable. With this method, a variety of unique substituted chiral fused bicyclic azepines, bearing multiple contiguous stereogenic centers, were facilely accessed in a straightforward, high‐yielding, and highly stereoselective manner under mild reaction conditions. Notably, the E/Z geometry of the CC bonds in the vinyl aziridine‐alkene substrates impact the cis/trans stereochemistry of the cycloadducts and up to six stereoisomers could be delivered.

Published: November 2015

AbstractThis paper presents a new approach in modeling the particle dispersion structure of micro‐nano silver particles of conductive adhesive considering the van der Waals interaction energy. As there are many possible combinations of hybrid micro‐nano system, this work only focuses on two types of micro‐nanoparticles interconnecting; the first is single microparticles with nanoparticles, and the second is two microparticles with nanoparticles. The particle coordinates were imported into cad software to produce 3D geometry, and finally, the finite element method was used to determine the electrical conductivity. The experimental data were taken at the volume ratios of the hybrid system using micro‐sized and nano‐sized particles at 50 : 50 for validation purpose. As a result, the predicted electrical conductivity shows a good agreement with experiment data with error less than 4%. Simulation result gives a value 1.46 × 101, 9.18, 6.86 and 4.54 S/cm for single‐micro/50 nanoparticles, single‐micro/75 nanoparticles, single‐micro/100 nanoparticles and single‐micro/125 nanoparticles, respectively. The electrical conductivity is optimum in a particular nano‐size number as it could settle interconnection path in shorter particle chain. The electrical conductivity show decreasing by increasing particle network chain due to nano‐particles added. © 2015 Curtin University of Technology and John Wiley & Sons, Ltd.

AbstractIsopropyl 3‐(3,4‐dihydroxyphenyl)‐2‐hydroxypropanoate (IDHP) is an investigational new drug having the capacity for treating ailments in the cardiovascular and cerebrovascular system. In this work, a rapid and sensitive method using high‐performance liquid chromatography coupled with electrospray ionization quadrupole time‐of‐flight tandem mass spectrometry (HPLC‐ESI‐Q‐TOF‐MS) was developed to reveal the metabolic profile of IDHP in rats after oral administration. The method involved pretreatment of the samples by formic acid–methanol solution (v/v, 5:95), chromatographic separation by an Agilent Eclipse XDB‐C18 column (150 × 4.6 mm i.dx., 5 μm) and online identification of the metabolites by Q‐TOF‐MS equipped with electrospray ionizer. A total of 16 metabolites from IDHP, including four phase I metabolites and 12 phase II metabolites, were detected and tentatively identified from rat plasma, urine and feces. Among these metabolites, Danshensu (DSS), a hydrolysis product of IDHP, could be further transformed to 11 metabolites. These results indicated that DSS was the main metabolite of IDHP in rats and the major metabolic pathways of IDHP in vivo were hydrolysis, O‐methylation, sulfation, glucuronidation and reduction. The results also demonstrated that renal route was the main pathway of IDHP clearance in rat. The present study provided valuable information for better understanding the efficacy and safety of IDHP.

Published: November 2015

AbstractA series of enantiomeric 2,6‐bis(1,2,3‐triazol‐4‐yl)pyridines (btp)‐containing ligands was synthesized by a one‐pot two‐step copper‐catalyzed amine/alkyne click reaction. The EuIII‐ and TbIII‐directed self‐assembly formation of these ligands was studied in CH3CN by monitoring their various photophysical properties, including their emerging circular dichroism and circularly polarized luminescence. The global analysis of the former enabled the determination of both the stoichiometry and the stability constants of the various chiral supramolecular species in solution.

AbstractBackgroundOverexpression of p16 is associated with improved outcomes among patients with oropharyngeal carcinoma. However, its role in the outcomes of patients with nasopharyngeal cancer (NPC) remains unclear.MethodsEighty‐six patients with NPC treated at MD Anderson Cancer Center from 2000 to 2014 were identified. Epstein‐Barr virus (EBV) and human papillomavirus (HPV) status were determined by in situ hybridization (ISH) and p16 by immunohistochemical staining.ResultsEBV positivity was associated with extended overall survival (OS; median, 95.0 vs 44.9 months; p < .004), progression‐free survival (PFS; median, 80.4 vs 28.1 months; p < .013), and locoregional control (median, 104.4 vs 65.5 months; p < .043). In patients with EBV‐positive tumors, p16 overexpression correlated with improved PFS (median, 106.3 vs 27.1 months; p < .02) and locoregional control (median, 93.6 vs 64.5 months; p < .02).ConclusionP16 overexpression is associated with improved PFS and locoregional control in patients with EBV‐positive NPC. P16 expression may complement EBV status in predicting treatment outcomes for patients with NPC. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1459–E1466, 2016

BackgroundThe primary treatment for head and neck adenoid cystic carcinoma (ACC) is surgery. Infrequently, however, ACC's propensity for perineural and base of skull invasion can preclude definitive surgical management. We present our experience with proton radiation therapy (RT) and concurrent platinum‐based chemotherapy.MethodsNine patients with unresectable node‐negative, nonmetastatic head and neck ACC received definitive proton RT and concurrent cisplatin. Outcomes and toxicities were recorded. A systematic review of the literature was performed.ResultsMedian follow‐up was 27 months (range, 9.2–48.3 months). Four patients achieved complete response at the primary site, and an additional 4 patients achieved stabilization of local disease. Only 1 patient developed local disease progression. Four patients had 5 acute grade 3 (G3) toxicities, and 1 patient developed a chronic G4 optic nerve disorder.ConclusionOur preliminary results suggest proton RT and concurrent chemotherapy is a definitive treatment option for select patients with head and neck ACC. © 2015 Wiley Periodicals, Inc.

Published: November 2015

AbstractBackgroundMicrovascular reconstruction in head and neck surgery is increasing in the elderly because of prolonged life expectancy. The purpose of this study was to evaluate the impact of age on outcomes after microvascular reconstruction.MethodsWe retrospectively reviewed 453 microvascular reconstructions and stratified patients according to age (40.8% >65 years old). Medical and surgical complications and flap success rates were evaluated according to the American Society of Anesthesiologists (ASA) score for physical status and age.ResultsOverall flap success and perioperative mortality were 96.1% and 0.7%, respectively. Minor medical complications were higher in the elderly (28.1% vs 15.3%; p = .001). High ASA scores affected rates of major surgical (20% vs 9.2%; p = .001) and minor medical complications (27.2% vs 13.3%; p < .001).ConclusionMicrovascular reconstruction is reliable in the elderly. Age should not be considered a contraindication by itself; comorbidities play a stronger role in predicting adverse events. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1488–E1492, 2016
