Regional and local stress field orientation inferred from quantitative analyses of extension joints: Case study from southern Italy
Authors: De Guidi Giorgio , Caputo Riccardo , Scudero Salvatore 
Published: February 2013

AbstractAn intense tectonic activity in eastern Sicily and southern Calabria (Italy) is well documented by the differential uplift of Late Quaternary coastlines and by the record of the strong historical earthquakes. The extensional belt that crosses this area is dominated by a well‐established WNW‐ESE–oriented stretching direction. However, this area is largely lacking of any structural analysis for defining the tectonics at a more local scale. The analysis of systematic extension joint sets affecting Pleistocene deposits presented in this paper allows to infer the causative tectonic stress tensor by means of a quantitative inversion technique. Local perturbations of the first‐order regional stress field are consequently recognized. Such perturbations are interpreted as due to interferences between large active faults and their particular geometrical setting. These results contribute to the understanding of the Quaternary tectonic evolution and the present‐day stress regime.

AbstractPredominant stretching structures in the Greater Himalayan Crystalline Complex (GHC) trend perpendicular to the belt and are linked to the southward exhumation or emplacement of the GHC between the South Tibet Detachment (STD) and the Main Central Thrust. However, our field investigations in southern Tibet reveal the widespread presence of gently dipping shear zones with a penetrative orogen‐parallel stretching lineation, which separates the Tethyan Himalayan Sequence and the underlying GHC. The shear zones are well preserved in the upper part of the GHC, south to and structurally lower than the STD. Field criteria, microstructures, and quartz fabrics indicate top‐to‐the‐east shearing in the Yadong shear zone (eastern GHC), coexistence of top‐to‐the‐east and top‐to‐the‐west shearing in the Nyalam shear zone (central GHC), but top‐to‐the‐west shearing in the Pulan shear zone (western GHC). Characteristic microstructures and slip systems of quartz in the high‐grade GHC rocks resulted from the lateral flow under upper amphibolite (up to 650–700 °C) to greenschist facies conditions. U‐Pb ages of metamorphic zircon rims by sensitive high‐resolution ion microprobe (SHRIMP) and laser ablation multi‐collector inductively coupled plasma mass spectrometry (LA‐MC‐ICP‐MS) analyses yield 28–26 Ma for the initiation of the Yadong and Nyalam shear zones and 22–15 Ma for the activation of the Pulan shear zone. In addition, 40Ar/39Ar cooling ages of biotite and muscovite suggest cessation of ductile sharing at 13–11 Ma on the Yadong shear zone, which is coeval with the activation of the STD. Combined with previous studies, we propose that initiation of orogen‐parallel extension marks the transition from burial/crustal thickening to exhumation of the GHC. Due to lateral crustal thickness gradients in a thickened crust, orogen‐parallel gravitational collapse occurred within the convergent Himalayan orogen in the late Oligocene‐Miocene. This tectonic denudation triggered and enhanced partial melting and ductile extrusion of the GHC in the Miocene.

Published: February 2013

AbstractIn spite of the burgeoning interest in green supply chain management in Western developed countries and large emerging economies, little research exists on the topic in small emerging and developing countries. In this study, we surveyed firms based in Dubai to identify the main drivers of green supply chain management and their impact on supply chain greening. We discuss theoretical and managerial implications of the findings. © 2013 Wiley Periodicals, Inc.
How Institutional Change Reconfigures Successful Value Chains: The Case of Western Pharma Corporations in China
Authors: Dierks Alexander , Kuklinski Christian Paul Jian Wei , Moser Roger 
Published: February 2013

AbstractManagement researchers have traditionally emphasized two main factors in the definition of corporate strategies: internal capabilities and industry competition. However, in less stable, transition economies it is particularly the changing institutional environment that influences strategy definition and performance of multinational corporations (MNCs) as shown by numerous international business (IB) scholars. Yet, how institutions matter remains a largely unresolved question. This article examines how institutions have affected the value chain configuration of Western pharmaceutical firms in China. Our research framework identifies four major strategic shifts along the value chain of Western firms in the pharmaceutical industry: upgrading along the value chain, outsourcing to contract service providers, expansion of geographical scope and diversification of product portfolio. The findings allow concrete managerial implications to be derived for decision makers of Western pharmaceutical firms operating in China. © 2013 Wiley Periodicals, Inc.
Culture Determines Business Models: Analyzing Home Depot's Failure Case in China for International Retailers from a Communication Perspective
Authors: Gao May Hongmei 
Published: February 2013

AbstractThis article is a result of a longitudinal case study regarding Home Depot's operation in China. From 2006 to 2011, the author conducted 37 in‐depth interviews with Home Depot executives, managers, lawyers, employees, suppliers, and consumers, as well as its Western and Chinese competitors. These interviews generated 500+ pages of transcripts and field notes. Home Depot entered China in 2006 by acquiring 12 stores from a Chinese company, Home Way. However, by September 2012 all Home Depot stores in China had been closed.This interview‐based single‐case‐study research has these notable contributions. First, this research stresses the importance of host culture in creating a business model when an international retailer expands to a foreign country. Second, the research develops a new Host Culture Analysis Framework: CELM (host Culture, business Environment, target consumer Lifestyle, and target consumer Mentality). Third, by applying the CELM framework to the Chinese market, this research suggests that Home Depot could have replaced its ineffective DIY (Do‐It‐Yourself) model with the new DIFM (Do‐It‐for‐Me) business model for China. Fourth, this article proposes a new urban boutique store (UBS) retail format for international retailers entering emerging markets. Finally, this research shows that in‐depth interview is a solid research method to be applied to case studies, for the discovery of deeper reasons of international expansion failures. © 2013 Wiley Periodicals, Inc.

A rapid and sensitive non‐radioactive method applicable for genome‐wide analysis of Saccharomyces cerevisiae genes involved in small RNA biology
Authors: Wu Jingyan , Huang Hsiao‐Yun , Hopper Anita K. 
Published: February 2013

AbstractConventional isolation and detection methods for small RNAs from yeast cells have been designed for a limited number of samples. In order to be able to conduct a genome‐wide assessment of how each gene product impacts upon small RNAs, we developed a rapid method for analysing small RNAs from Saccharomyces cerevisiae wild‐type (wt) and mutants cells in the deletion and temperature‐sensitive (ts) collections. Our method implements three optimized techniques: a procedure for growing small yeast cultures in 96‐deepwell plates, a fast procedure for small RNA isolation from the plates, and a sensitive non‐radioactive northern method for RNA detection. The RNA isolation procedure requires only 4 h for processing 96 samples, is highly reproducible and yields RNA of good quality and quantity. The non‐radioactive northern method employs digoxigenin (DIG)‐labelled DNA probes and chemiluminescence. It detects femtomole levels of small RNAs within 1 min exposure time. We minimized the processing time for large‐scale analysis and optimized the stripping and reprobing procedures for analyses of multiple RNAs from a single membrane. The method described is rapid, sensitive, safe and cost‐effective for genome‐wide screens of novel genes involved in the biogenesis, subcellular trafficking and stability of small RNAs. Moreover, it will be useful to educational laboratory class venues and to research institutions with limited access to radioisotopes or robots. Copyright © 2013 John Wiley & Sons, Ltd.
Is it worth assessing progress as early as week 2 to adapt antidepressive treatment strategy? Results from a study on agomelatine and a global meta-analysis

Published: February 2013

AbstractContext:A delay of 4–8 weeks before modifying the prescribed antidepressant treatment is usually proposed when incomplete treatment response is observed. A number of studies nevertheless proposed that the lack of early improvement (usually 20% decrease of severity at week 2) is predictive of the absence of subsequent treatment response, potentially saving weeks of inadequate treatment, but with no information for non-interventional studies devoted to outpatients.Method:Two thousand nine hundred and thirty-eight outpatients with major depressive disorder were included in a multicentre, non-interventional study, assessing at inclusion, week 2 and week 6, mood (QIDS-C, CGI, PGI and VAS) sleep (LSEQ) and functionality (SDS). All metrics at week 2 were tested for their capacity to predict response (and then remission) at week 6, all patients being treated by agomelatine. A meta-analysis of all studies (n = 12) assessing the predictive role of improvement at week 2 was also performed, assessing specific effect size of published studies and the weight of the different parameters they used.Results:The QIDS-C and the CGI-I were the only instruments with an area under the curve over 0.7, with different cut-offs for treatment response and remission. A decrease of more than five points at the QIDS-C had the highest positive predictive value for treatment response, and a CGI-I over three had the highest negative predictive value, which would favour relying on the clinicians for warning (too high CGI-I), and on instruments for confidence (favourable decrease of the QIDS-C). The meta-analysis of all studies also detected a large effect size of early improvement, stressing how rating week 2 severity could be beneficial in clinical practice.Conclusions:Previous reports stressing the interest of an assessment at week 2 were reinforced by the present results, which also defined more accurately what could be the most appropriate cut-offs, and how combining these early results could be more effective.
“In Favour of Popery”: Patriotism, Protestantism, and the Gordon Riots in the Revolutionary British Atlantic
Authors: Jones Brad A. 
Published: February 2013

AbstractIn 1778, in response to news of the American alliance with France, the British government proposed a series of Catholic relief bills aimed at tolerating Catholicism in England, Scotland, and Ireland. Officials saw the legislation as a pragmatic response to a dramatically expanded war, but ordinary Britons were far less tolerant. They argued that the relief acts threatened to undermine a widely shared Protestant British patriotism that defined itself against Catholicism and France. Through an elaborate and well-connected popular print culture, Britons living in distant Atlantic communities, such as Kingston (Jamaica), Glasgow, Dublin, and New York City, publicly engaged in a radical brand of Protestant patriotism that began to question the very legitimacy of their own government. Events culminated in June 1780, with five days of violent, deadly rioting in the nation's capitol. Yet the Gordon Riots represent only the most famous example of this new, more zealous defense of Protestant Whig Britishness. In the British Caribbean and North America, unrelenting fears of French invasions and the perceived incompetence of the government mixed with an increasingly confrontational Protestant political culture to expose the fragile nature of British patriotism. In Scotland, anti-Catholic riots drove the country to near rebellion in early 1779, while in Ireland, Protestants and Catholics took advantage of this political instability to make demands for economic and political independence, culminating in the country's legislative autonomy in 1782. Ultimately, Catholic relief and the American alliance with France fundamentally altered how ordinary Britons viewed their government and, perhaps, laid the foundations for the far more radical political culture of the 1790s.
Dietary calcium intake is associated with adiposity, metabolic profile, inflammatory state and blood pressure, but not with erythrocyte intracellular calcium and endothelial function in healthy pre-menopausal women

Published: February 2013

Recent studies have suggested that dietary Ca may have beneficial effects on adiposity, insulin resistance, dyslipidaemia and blood pressure (BP). One potential mechanism underlying these benefits involves modifications in intracellular Ca concentration ([Ca2+]i). The present study aimed to evaluate the associations of dietary Ca with adiposity, erythrocyte [Ca2+]i, metabolic profile, BP, inflammatory state and endothelial function in healthy pre-menopausal women. In the present cross-sectional study, seventy-six women aged 18–50 years were submitted to the evaluation of dietary intake, anthropometric parameters, body composition, erythrocyte [Ca2+]i, biochemical variables, endothelial function and BP. A FFQ was used to assess usual dietary intake. Endothelial function was evaluated by serum concentrations of adhesion molecules and by the peripheral arterial tonometry (PAT) method, using Endo-PAT 2000®. Participants were allocated into two groups according to Ca intake: low-Ca group (LCG;n32; < 600 mg/d) and high-Ca group (HCG;n44; ≥ 600 mg/d). Women in the LCG compared with those in the HCG exhibited, after adjustments for potential confounders, higher values of BMI, waist circumference, waist:height ratio, percentage of body fat, insulin, homeostasis model assessment of insulin resistance, leptin, diastolic and mean BP; and lower levels of HDL-cholesterol, adiponectin and vascular cell adhesion molecule 1. Endothelial function assessed by PAT and [Ca2+]iwas similar in both groups. Subjects in the HCG had lower OR for prevalent overweight, obesity, abdominal obesity, insulin resistance, HDL-cholesterol < 600 mg/l and systolic BP >120 mmHg. The findings of the present study suggest that high Ca intake is inversely associated with some cardiovascular risk factors.

Published: February 2013

A class of microstrip lowpass filter (LPF) with a sharp‐rejection, ultra‐broad stopband is reported. It employs rat‐race directional couplers properly arranged to operate as bandstop transversal filtering sections (TFSs). The theoretical foundations of this LPF approach are described, and the performance control of its building bandstop TFS is verified. Moreover, a proof‐of‐concept microstrip LPF prototype with a 3 dB cutoff frequency of 1 GHz and a 20 dB stopband up to 5.86 GHz has been built and tested.
Investigation of transient photocurrent response of triple pn junction structure
Authors: Schidl S. , Polzer A. , Dong J. , Schneider‐Hornstein K. , Zimmermann H. 
Published: February 2013

The transient photocurrent response of a vertically stacked triple pn junction structure, which can detect three different colours simultaneously, is investigated. The triple pn junction structure is designed based on the effect that the penetration depth in silicon depends on light wavelength. To increase the bandwidth of optical sensor systems the transient photocurrent response is a critical parameter. The transient response is measured by applying three different light wavelengths to this triple junction structure. This triple pn junction structure is fabricated in a 0.6 µm BiCMOS technology using a p−p+ epitaxial wafer without any process modification. Based on the measurement results, it can be concluded that this triple pn junction structure can be applied to optical sensors without optical filters and the total data rate of this structure can reach up to 100 Mbit/s.

Authors: Kotiranta M. , Krozer V. 
Published: February 2013

A helix travelling‐wave tube for 825 GHz has been designed and its broadband amplification performance has been demonstrated with 3D particle‐in‐simulations. The design utilises a helix slow‐wave structure with a square form and input/output couplers based on a transition from the helix to a coplanar waveguide and further to a rectangular waveguide with a through‐substrate post coupler. A simulated small‐signal gain of 18.3 dB with an output power of over 25 dBm at 1 dB compression point and a 3 dB instantaneous bandwidth of 8% have been obtained.
Cylindrical high impedance surface aided horizontally polarised omnidirectional antenna
Authors: Sugiura S. , Iizuka H. 
Published: February 2013

Cylindrical high impedance surface (HIS) structures and their E‐plane omnidirectional antenna application are presented at the 2.0 GHz band. The diameter of the cylinder is 39.2 mm, when the φ‐direction periodicity is chosen as three. The HIS, when illuminated by plane waves, not only reflects them in the direction of arrival with zero phase, but also transmits them in other directions to a comparable degree, which is caused by half‐wavelength resonance of all of the patches. A dipole antenna element situated close to the HIS, the φ‐direction periodicity of which is three, exhibits VSWR = 1.5 and an omnidirectional E‐plane pattern at 2.14 GHz.
A new way to protect privacy in large-scale genome-wide association studies

Published: February 2013

Abstract
Motivation: Increased availability of various genotyping techniques has initiated a race for finding genetic markers that can be used in diagnostics and personalized medicine. Although many genetic risk factors are known, key causes of common diseases with complex heritage patterns are still unknown. Identification of such complex traits requires a targeted study over a large collection of data. Ideally, such studies bring together data from many biobanks. However, data aggregation on such a large scale raises many privacy issues.
Results: We show how to conduct such studies without violating privacy of individual donors and without leaking the data to third parties. The presented solution has provable security guarantees.

GalaxyGemini: a web server for protein homo-oligomer structure prediction based on similarity
Authors: Lee Hasup , Park Hahnbeom , Ko Junsu , Seok Chaok 
Published: February 2013

Abstract
Summary: A large number of proteins function as homo-oligomers; therefore, predicting homo-oligomeric structure of proteins is of primary importance for understanding protein function at the molecular level. Here, we introduce a web server for prediction of protein homo-oligomer structure. The server takes a protein monomer structure as input and predicts its homo-oligomer structure from oligomer templates selected based on sequence and tertiary/quaternary structure similarity. Using protein model structures as input, the server shows clear improvement over the best methods of CASP9 in predicting oligomeric structures from amino acid sequences.

Published: February 2013

AbstractØresland, V., and Ulmestrand, M. 2013. European lobster subpopulations from limited adult movements and larval retention. – ICES Journal of Marine Science, 70: 532–539. Adults and larvae of the European lobster, Homarus gammarus, were studied within and around the Swedish Kåvra lobster reserve (2.2 km2). Tagging of 4016 lobsters within the reserve showed that the lobsters have limited movement out of the reserve. Only 58 lobsters (1.4% of all tagged lobsters) were recaptured ≥1 km from the reserve and 5658 recaptures were obtained inside the reserve. Light trap catches showed that stage 1 larvae had a peak occurrence during <2 weeks, in early August, 2007–2009. The mean depth distribution of stage 1 larvae was 16 m and very few larvae were found in the low saline surface layer. No later stages were found in horizontal net tows. The lobsters inside the reserve provided stage 1 larvae to the nearby area. A persistent retention of water masses was found at 16-m depth (below the sharp halocline) in the area (16 km2) around the reserve using IMR GPS Current Drifters. In sharp contrast, surface drifters showed strong offshore and inshore movements. The Swedish archipelago might harbour many lobster and other decapod subpopulations, if the larval stages occur in a large proportion below the sharp halocline and if adult movements are limited.
