Istanbul Strait Road Tube Crossing: Design of NATM Tunnels and Asian Transition Box Excavation
Authors: Kohlböck Bernhard , Koc Onur , Ayten Türkay 
Published: August 2016

AbstractIstanbul is among the fastest growing megacities in the world and the only one located on two continents, divided by the Bosphorus strait. The geographic situation together with the enormous growth of population impose great challenges, especially considering urban and infrastructure development. The Bosphorus Strait Road tunnel, also called Eurasia Tunnel, is the first road tunnel connecting the European and the Asian side of the city with the aim of alleviating Istanbul's traffic pressure and reducing the travel time between Kazlıçeşme and Göztepe from 100 to 15 minutes. This article focuses on the design of the twin tunnels and the transition box from NATM to TBM on the Asian side.

Published: August 2016

AbstractThe population increase in Istanbul is also reflected in car ownership, which brings an extensive traffic load to the city, especially to the two bridges over the Bosphorus. After feasibility studies, a double deck, 3.4 km subsea tunnel with a 13.7 m diameter at a maximum depth of 106 m below sea level and a capacity of 100,000 cars/day was initiated as a solution for the city. The tunnel, excavated by a custom‐made mixshield slurry TBM, passes through very complex geological structures including the Trakya formation, transition zones and marine sediments in a highly seismic area.
The Pervasiveness And Trajectory Of Methodological Choices: A 20‐Year Review Of Human Resource Management Research
Authors: Bainbridge Hugh T. J. , Sanders Karin , Cogin Julie A. , Lin Cai‐Hui 
Published: August 2016

AbstractThis article examines the methodological choices of researchers studying the HR practices–outcome relationship via a content analysis of 281 studies published across the past 20 years. The prevalence and trajectory of change over time are reported for a wide range of methodological choices relevant to internal, external, construct, and statistical conclusion validity. While the results indicate a high incidence of potentially problematic cross‐sectional, single‐informant, and single‐level designs, they also reveal significant improvements over time across many validity relevant methodological choices. This broad‐based improvement in the methodological underpinnings of HR research suggests that researchers and practitioners can view the findings reported in the HR literature with increasing confidence. Directions for future research are provided. © 2016 Wiley Periodicals, Inc.
An adaptive stochastic inverse solver for multiscale characterization of composite materials
Authors: Hu Nan , Fish Jacob , McAuliffe Colin 
Published: August 2016

SummaryWe present an adaptive variant of the measure‐theoretic approach for stochastic characterization of micromechanical properties based on the observations of quantities of interest at the coarse (macro) scale. The salient features of the proposed nonintrusive stochastic inverse solver are identification of a nearly optimal sampling domain using enhanced ant colony optimization algorithm for multiscale problems, incremental Latin‐hypercube sampling method, adaptive discretization of the parameter and observation spaces, and adaptive selection of number of samples. A complete test data of the TORAY T700GC‐12K‐31E and epoxy #2510 material system from the National Institute for Aviation Research report is employed to characterize and validate the proposed adaptive nonintrusive stochastic inverse algorithm for various unnotched and open‐hole laminates.

Published: August 2016

RationaleWhile natural products isolated from medicinal plants can serve as a rich source of biologically active metabolites, mixtures of structurally related compounds of a polar nature are often difficult to chemically resolve by traditional separation techniques. Chemical derivatization to reduce metabolite polarity combined with liquid chromatography (LC) is the strategy presented here to resolve a mixture of structurally related natural product glycosides solvent extracted from the medicinal herb Teucrium polium for mass spectrometric characterization.MethodsThe partially purified plant extract was subjected to chemical derivatization and electrospray ionization mass spectrometry (ESI‐MS) fragmentation pattern analysis allowed for structural characterization of iridoid and secoiridoid glycosides. Selected ions were subjected to tandem mass spectrometric (MS/MS) analysis with a relatively higher‐energy collision dissociation to assist in structural elucidation.ResultsPermethylation replaced all protons from free hydroxyl and amino groups with methyls and resulted in increases in both hydrophobicity, for facilitated chromatographic separation, and proton affinity, for enhanced chemical ionization. Protonated and/or sodiated adducts were observed for the six compounds detected in positive‐ion mode ESI‐MS with a mass accuracy of less than 2 ppm.ConclusionsPermethylation combined with LC/MS analysis is shown here to be an effective chemical practice for separating and characterizing iridoid glucosinolates and is expected to be well suited for the chemical characterization of other polar natural‐product mixtures of closely related compounds.

A speculative approach to spatial‐temporal efficiency with multi‐objective optimization in a heterogeneous cloud environment
Authors: Liu Qi , Cai Weidong , Shen Jian , Fu Zhangjie , Liu Xiaodong , Linge Nigel 
Published: August 2016

AbstractA heterogeneous cloud system, for example, a Hadoop 2.6.0 platform, provides distributed but cohesive services with rich features on large‐scale management, reliability, and error tolerance. As big data processing is concerned, newly built cloud clusters meet the challenges of performance optimization focusing on faster task execution and more efficient usage of computing resources. Presently proposed approaches concentrate on temporal improvement, that is, shortening MapReduce time, but seldom focus on storage occupation; however, unbalanced cloud storage strategies could exhaust those nodes with heavy MapReduce cycles and further challenge the security and stability of the entire cluster. In this paper, an adaptive method is presented aiming at spatial–temporal efficiency in a heterogeneous cloud environment. A prediction model based on an optimized Kernel‐based Extreme Learning Machine algorithm is proposed for faster forecast of job execution duration and space occupation, which consequently facilitates the process of task scheduling through a multi‐objective algorithm called time and space optimized NSGA‐II (TS‐NSGA‐II). Experiment results have shown that compared with the original load‐balancing scheme, our approach can save approximate 47–55 s averagely on each task execution. Simultaneously, 1.254‰ of differences on hard disk occupation were made among all scheduled reducers, which achieves 26.6% improvement over the original scheme.

SPAM revisited for median filtering detection using higher‐order difference
Authors: Agarwal Saurabh , Chand Satish , Skarbnik Nikolay 
Published: August 2016

AbstractIn this paper, we propose a robust median filtering detection scheme utilizing the conditional joint distribution of high‐order differences. The higher‐order differences provide additional information about the correlation between a pixel and its neighbors. The relationship between a pixel and its neighbors becomes more prominent in median‐filtered images as compared with non‐median filtered images. We evaluate the performance of our method and compare it with the state of the art median filtering detection techniques on multiple databases in various environments. We use a linear discriminant classifier based on Moore–Penrose pseudoinverse matrix for classifying the median and non‐median filtered images. Experimentally, we find that our method is more effective for all types of images including uncompressed and highly compressed JPEG low‐resolution images. We also evaluate the performance of our method on Gaussian‐filtered, averaging‐filtered, and median‐filtered images of the BOWS2 and UCID databases. Copyright © 2016 John Wiley & Sons, Ltd.

Published: August 2016

AbstractThe design and construction of sustainable and durable bridges with low maintenance costs is one of the tasks of road and railway administrations of the European Countries. The structures must be safe, economical and need less maintenance during their service life. All these needs can be found in integral abutment bridges. This solution, which eliminates the bearings and expansion joints, leads to low construction and maintenance costs. Integral bridges also have good earthquake resistance. Bridges are vital structures in the transport infrastructure; it is a fact that, in the last decades, composite bridges have become a popular solution in many European countries as a cost‐effective and aesthetic alternative to concrete bridges. Their competitiveness depends on several aspects, such as site conditions, local costs of materials and personnel and the contractor's experience. The main topics of this paper are: design of integral bridges, innovative composite dowels for shear transmission, construction of bridges in Romania, structural analysis of bridges and monitoring.
Iron Group Hydrides in Noyori Bifunctional Catalysis
Authors: Morris Robert H. 
Published: August 2016

AbstractThis is an overview of the hydride‐containing catalysts prepared in the Morris group for the efficient hydrogenation of simple ketones, imines, nitriles and esters and the asymmetric hydrogenation and transfer hydrogenation of prochiral ketones and imines. The work was inspired by and makes use of Noyori metal‐ligand bifunctional concepts involving the hydride‐ruthenium amine‐hydrogen HRuNH design. It describes the synthesis and some catalytic properties of hydridochloro, dihydride and amide complexes of ruthenium and in one case, osmium, with monodentate, bidentate and tetradentate phosphorus and nitrogen donor ligands. The iron hydride that has been identified in a very effective asymmetric transfer hydrogenation process is also mentioned. The link between the HMNH structure and the sense of enantioinduction is demonstrated by use of simple transition state models.

OBJECTIVETo determine the prevalence of multidrug-resistant organisms (MDROs) colonizing in pediatric refugees admitted to a University Children Hospital in Germany.DESIGNRetrospective observational study.SETTINGGeneral pediatric and pediatric surgery units.PATIENTSIn Germany, recommendations for MDRO screening of pediatric refugees were recently published. According to these and institutional recommendations, all hospitalized pediatric refugees were screened for MDROs between October 2015 and March 2016.METHODSUsing electronic surveillance data, we performed a chart review to identify the prevalence of MDROs among and the clinical diagnoses of pediatric refugees.RESULTSAmong 325 patients hospitalized for various causes, most frequently gastroenteritis (30.9%), MDROs were detected in 33.8%. Most of these patients were colonized with multidrug-resistant Gram-negative (MRGN) bacteria (113 isolates), mostly 2MRGN/ESBL (87 isolates); some patients were colonized with methicillin-resistantStaphylococcus aureus(MRSA, 22 isolates); and 1 patient was colonized with vancomycin-resistant enterococci (VRE). Among 110 refugee patients, we detected single colonization with an MDRO in 84 patients (76.4%), co-colonization with 2 pathogens in 23 patients (20.9%), and triple colonization in 3 patients (2.7%). However, infections with MDROs occurred in only 3.6% of pediatric refugees. The peak of positive MDRO screening results in 2015 correlated with an increased hospitalization rate.CONCLUSIONImplementation of infection control measures among pediatric refugees is challenging. Due to the high frequency of MDROs in these patients, current screening, isolation, and treatment strategies may have to be adapted.Infect Control Hosp Epidemiol2016;1–5
Neuroticism's prospective association with mental disorders halves after adjustment for baseline symptoms and psychiatric history, but the adjusted association hardly decays with time: a meta-analysis on 59 longitudinal/prospective studies with 443 313 participants
Authors: Jeronimus B. F. , Kotov R. , Riese H. , Ormel J. 
Published: August 2016

BackgroundThis meta-analysis seeks to quantify the prospective association between neuroticism and the common mental disorders (CMDs, including anxiety, depression, and substance abuse) as well as thought disorders (psychosis/schizophrenia) and non-specific mental distress. Data on the degree of confounding of the prospective association of neuroticism by baseline symptoms and psychiatric history, and the rate of decay of neuroticism's effect over time, can inform theories about the structure of psychopathology and role of neuroticism, in particular the vulnerability theory.MethodThis meta-analysis included 59 longitudinal/prospective studies with 443 313 participants.ResultsThe results showed large unadjusted prospective associations between neuroticism and symptoms/diagnosis of anxiety, depression, and non-specific mental distress (d = 0.50–0.70). Adjustment for baseline symptoms and psychiatric history reduced the associations by half (d = 0.10–0.40). Unadjusted prospective associations for substance abuse and thought disorders/symptoms were considerably weaker (d = 0.03–0.20), but were not attenuated by adjustment for baseline problems. Unadjusted prospective associations were four times larger over short (<4 year) than long (⩾4 years) follow-up intervals, suggesting a substantial decay of the association with increasing time intervals. Adjusted effects, however, were only slightly larger over short v. long time intervals. This indicates that confounding by baseline symptoms and psychiatric history masks the long-term stability of the neuroticism vulnerability effect.ConclusionHigh neuroticism indexes a risk constellation that exists prior to the development and onset of any CMD. The adjusted prospective neuroticism effect remains robust and hardly decays with time. Our results underscore the need to focus on the mechanisms underlying this prospective association.

Published: August 2016

BackgroundIt has been observed that mental disorders, such as psychosis, are more common for people in some ethnic groups in areas where their ethnic group is less common. We set out to test whether this ethnic density effect reflects minority status in general, by looking at three situations where individual characteristics differ from what is usual in a locality.MethodUsing data from the South East London Community Health study (n = 1698) we investigated associations between minority status (defined by: ethnicity, household status and occupational social class) and risk of psychotic experiences, common mental disorders and parasuicide. We used a multilevel logistic model to examine cross-level interactions between minority status at individual and neighbourhood levels.ResultsBeing Black in an area where this was less common (10%) was associated with higher odds of psychotic experiences [odds ratio (OR) 1.34 95% confidence interval (CI) 1.07–1.67], and attempted suicide (OR 1.84 95% CI 1.19–2.85). Living alone where this was less usual (10% less) was associated with increased odds of psychotic experiences (OR 2.18 95% CI 0.91–5.26), while being in a disadvantaged social class where this was less usual (10% less) was associated with increased odds of attempted suicide (OR 1.33 95% CI 1.03–1.71). We found no evidence for an association with common mental disorders.ConclusionsThe relationship between minority status and mental distress was most apparent when defined in terms of broad ethnic group but was also observed for individual household status and occupational social class.
Robust 2D map building with motion-free ICP algorithm for mobile robot navigation
Authors: Hwang YoSeop , Lee JangMyung 
Published: August 2016

SUMMARYA new motion-free iterative closest point (ICP) algorithm is proposed for building a two-dimensional (2D) map for mobile robot navigation. A laser range finder (LRF) sensor is installed on a mobile robot to scan and measure the depth data of the environment to form a 2D map during mobile robot navigation. Because the scanning and navigation motions are performed independently, the scanned data contain distortions from the motions of the mobile robot. To compensate for the distortions, the proposed motion-free ICP algorithm estimates the effects of the dynamic motions of the robot on the scanning process. That is, the motion-free algorithm compensates for the distance measurement errors related to the dynamic changes in the mobile robot's velocity. Experiments were performed with actual velocity changes of a mobile robot to demonstrate and verify the effective performance of the proposed algorithm.
THE CARIES MANAGEMENT SYSTEM: UPDATING COST-EFFECTIVENESS WITH 4-YEAR POSTTRIAL DATA
Authors: Warren Emma , Curtis Bradley H. , Jia Nan , Evans R. Wendell 
Published: August 2016

Objectives: Long-term follow-up of the Caries Management System (CMS) protocol demonstrated that regular monitoring and noninvasive management of dental caries is effective in reducing the number of caries-related events over a 7-year period. This analysis complements the authors’ original economic evaluation of the CMS by re-evaluating the per-protocol cost-effectiveness of the CMS approach.Methods: An individual patient-simulation Markov model was developed previously, based on 3-year randomized-controlled trial (RCT) data, to simulate the incidence and progression of dental caries, and resultant interventions, and to evaluate the lifetime cost-effectiveness of the CMS versus standard dental care from the Australian private dental practitioner perspective (in which the baseline age distribution was similar to that of the Australian population). The 4-year posttrial follow-up data are used to re-evaluate the long-term cost-effectiveness of the CMS in a more real-life setting.Results: The reduction in caries risk was maintained among those practices within which the CMS protocols were adhered to. The per-protocol model appears to be reasonably accurate at predicting the risk of restorative events in the posttrial follow-up period. The per-protocol lifetime cost per restorative event avoided is AUD1,980 (USD1,409; 1 AUD = 0.71 USD).Conclusions: The current analysis confirms that the CMS approach is both effective, when the protocols are adhered to appropriately, and cost-effective compared with standard care in the Australian private practice setting.
ASPECTS OF PATIENT REPORTED OUTCOMES IN RARE DISEASES: A DISCUSSION PAPER
Authors: Rüther Alric , Elstein Deborah , Wong-Rieger Durhane , Guyatt Gordon 
Published: August 2016

Objectives: A patient reported outcome (PRO) is “any report of the status of a patient's health condition that comes directly from the patient without interpretation of the patient's response by a clinician or anyone else” (USFDA 2009). PROs are discussed widely, and many regard the patients’ perspective on treatment benefit as very valuable. Although many PROs have shown satisfactory measurement properties including reliability, validity, and responsiveness, there is great concern about risk of bias, that is, in clinical trials.Methods: Differences in perspectives of PRO measurement in rare diseases are given arising from methodology, clinical, HTA, and patient advocacy views.Results: PROs are playing an important role in dealing with treatment benefit especially in small sample size as occurring often in rare diseases. Challenges remain especially regarding lack of responsiveness of generic measures, limited capture of all patient relevant aspects, study design and high risk of bias.Conclusions: PROs seem a valuable instrument to detect patient relevant aspects in rare diseases. They should be seen in addition to other approved assessment methods as randomized controlled trials but not as their substitute.
TOWARD A CRITICAL ENVIRONMENTAL JUSTICE STUDIES
Authors: Pellow David N. 
Published: August 2016

AbstractIn this paper I expand upon the recent use of the term “Critical Environmental Justice Studies.” This concept is meant to capture new developments in Environmental Justice (EJ) Studies that question assumptions and gaps in earlier work in the field. Because this direction in scholarship is still in its formative stages, I take this opportunity to offer some guidance on what Critical Environmental Justice (CEJ) Studies might look like and what it could mean for theorizing the relationship between race (along with multiple additional social categories) and the environment. I do so by (1) adopting a multi-disciplinary approach that draws on several bodies of literature, including critical race theory, political ecology, ecofeminist theory, and anarchist theory, and (2) focusing on the case of Black Lives Matter and the problem of state violence.
