Static field test on flexural behavior of reinforced concrete T-beam bridge strengthened with MPC-PSWR
Authors: Gao Hongshuai , Sun Quansheng 
Published: March 2020

PurposeWith the rapid development of transportation and the continuous increase of traffic volume and load level, some bridges cannot meet the use requirements, and the demand for bridge strengthening is growing. Furthermore, bridges are affected by factors such as structure and external environment. With the increase of service time, the deterioration of bridges is also increasing. In order to avoid the waste caused by demolition and reconstruction, it is necessary to strengthen the bridge accurately and effectively to improve the bearing capacity and durability, eliminate the hidden dangers, and ensure the normal operation of the bridge. It is of great significance to study the strengthening methods. Compared with traditional strengthening methods, the advantages of using new materials and new technology to strengthen bridges are more obvious. This paper introduces a new method for bridge active strengthening, called modified polyurethane cement with prestressed steel wire rope (MPC-PSWR).Design/methodology/approachRelying on the actual bridge strengthening project, five T-beams of the superstructure of the bridge are taken as the research object, and the T-beams before and after strengthening are evaluated, calculated, and analyzed by finite element simulation and field load test. By comparing the numerical simulation and load test data, the strengthening effect of modified polyurethane cement with prestressed steel wire rope on stiffness, strength, and bearing capacity is verified, which proves that the strengthening effect of MPC-PSWR is effective for strengthening.FindingsMPC-PSWR can effectively reduce deflection, cracks, and strain, thereby significantly improving the flexural capacity of existing bridges. Under the design load, the deflection, crack width, and stress of the strengthened beams decrease in varying degrees. The overall performance of the beams strengthened by MPC-PSWR has been improved, and the flexural performance meets the requirements of the code.Originality/valueMPC-PSWR is an innovative bridge-strengthening method. Through the analysis of its MPC-PSWR effect, the MPC-PSWR method with reference to significance for the design and construction of similar bridges is put forward.

Authors: Zhang Wenping , Du Wei , Bian Yiyang , Peng Chih-Hung , Jiang Qiqi 
Published: March 2020

PurposeThe purpose of this study is to unpack the antecedents and consequences of clickbait prevalence in online media at two different levels, namely, (1) Headline-level: what characteristics of clickbait headlines attract user clicks and (2) Publisher-level: what happens to publishers who create clickbait on a prolonged basis.Design/methodology/approachTo test the proposed conjectures, the authors collected longitudinal data in collaboration with a leading company that operates more than 500 WeChat official accounts in China. This study proposed a text mining framework to extract and quantify clickbait rhetorical features (i.e. hyperbole, insinuation, puzzle, and visual rhetoric). Econometric analysis was employed for empirical validation.FindingsThe findings revealed that (1) hyperbole, insinuation, and visual rhetoric entice users to click the baited headlines, (2) there is an inverted U-shaped relationship between the number of clickbait headlines posted by a publisher and its visit traffic, and (3) this non-linear relationship is moderated by the publisher's age.Research limitations/implicationsThis research contributes to current literature on clickbait detection and clickbait consequences. Future studies can design more sophisticated methods for extracting rhetorical characteristics and implement in different languages.Practical implicationsThe findings could aid online media publishers to design attractive headlines and develop clickbait strategies to avoid user churn, and help managers enact appropriate regulations and policies to control clickbait prevalence.Originality/valueThe authors propose a novel text mining framework to quantify rhetoric embedded in clickbait. This study empirically investigates antecedents and consequences of clickbait prevalence through an exploratory study of WeChat in China.

Understanding barriers to circular economy: cases from the manufacturing industry
Authors: Jaeger Bjoern , Upadhyay Arvind 
Published: March 2020

PurposeMost companies include a commitment for sustainable growth involving a switch towards the circular economy (CE) model. The purpose of this paper is to present barriers to CE adoption identified by a literature review. The paper also addresses the particular challenges faced by manufacturers by answering the research question: What are the dominant barriers faced by the manufacturing industry in moving towards a CE?Design/methodology/approachThis paper presents a literature review of research identifying barriers for adopting to CE in the manufacturing sector. The literature review is followed by a case study identifying barriers to CE as seen by ten companies within manufacturing, including the GS1 global information standardisation agency used by all manufacturers.FindingsThe manufacturers investigated focus mostly on recycling and waste reduction. These policies have low or very low CE effect. High CE effect policies like maintenance and reuse targeting the CE ideal of no waste, are nearly non-existent. The results identified seven main barriers to the CE: (1) high start-up costs, (2) complex supply chains, (3) challenging business-to-business (B2B) cooperation, (4) lack of information on product design and production, (5) lack of technical skills, (6) quality compromise and (7) disassembly of products is time-consuming and expensive.Research limitations/implicationsThe data come from participants in a single country, Norway, although the manufacturers are multinational companies adhering to enterprise policies.Practical implicationsThis research shows that all the companies interviewed are well aware of the growing need for their company to move towards more sustainable operations involving CE concepts. The barriers identified are explored, and the findings could guide such companies in their efforts to move to maintenance, reuse, remanufacture and recycle (M+3R) operational model.Social implicationsThe study has found that the major barriers for implementation of CE are quality issues in recycled materials, supply chain complexities, coordination problems between companies, design and production of the product, disassembly of products and high start-up/ investment costs.Originality/valueThe research shows how the transition towards a CE takes place in manufacturing industries by studying the manufacturing sector.
Benefits of formalized computational modeling for understanding user behavior in online privacy research
Authors: Schürmann Tim , Gerber Nina , Gerber Paul 
Published: March 2020

PurposeOnline privacy research has seen a focus on user behavior over the last decade, partly to understand and explain user decision-making and seeming inconsistencies regarding users' stated preferences. This article investigates the level of modeling that contemporary approaches rely on to explain said inconsistencies and whether drawn conclusions are justified by the applied modeling methodology. Additionally, it provides resources for researchers interested in using computational modeling.Design/methodology/approachThe article uses data from a pre-existing literature review on the privacy paradox (N = 179 articles) to identify three characteristics of prior research: (1) the frequency of references to computational-level theories of human decision-making and perception in the literature, (2) the frequency of interpretations of human decision-making based on computational-level theories, and (3) the frequency of actual computational-level modeling implementations.FindingsAfter excluding unrelated articles, 44.1 percent of investigated articles reference at least one theory that has been traditionally interpreted on a computational level. 33.1 percent of all relevant articles make statements regarding computational properties of human cognition in online privacy scenarios. Meanwhile, 5.1 percent of all relevant articles apply formalized computational-level modeling to substantiate their claims.Originality/valueThe findings highlight the importance of formal, computational-level modeling in online privacy research, which has so far drawn computational-level conclusions without utilizing appropriate modeling techniques. Furthermore, this article provides an overview of said modeling techniques and their benefits to researchers, as well as references for model theories and resources for practical implementation.
Leading the experience ecosystem revolution: innovating offerings as interactive platforms
Authors: Ramaswamy Venkat 
Published: March 2020

Purpose
The author explains how networked interaction, propelled by the internet and the forces of digitalization, ubiquitous connectivity, globalization and social media has become the new locus for creating value. And how that networked interaction is accelerating the shift of value creation towards the experiences of individuals who want to define choices in a manner that reflects their view of value and their own expressions of personalization. 10;

Design/methodology/approach
The article explains that every enterprise is now faced with the challenge of learning how to create valuable impacts of experienced outcomes through smarter, connected offerings and the networked interactions of individuals.

Findings
Instead of having fixed economic value, offerings are increasingly a means for the dynamic creation of experience value through ongoing and new types of networked interactions.

Practical implications
Rather than simply elevating the user experience of a good or service, the co-created experience itself becomes the product.

Originality/value
The Starbucks and Burberry examples suggest how offerings are being enhanced by interactive technologies that open up new sources and avenues of experience value creation. The article explains how any enterprise can now adopt a strategy of ‘capabilities as a service’ by innovating its own ecosystems of customer and stakeholder experiences.
Plant performance and survival across transplant experiments depend upon temperature and precipitation change along elevation
Authors: Midolo Gabriele , Wellstein Camilla 
Published: March 2020

Abstract

Understanding how plant individuals perform in non‐local sites is key in the context of contemporary range shifts along elevation. Transplant experiments conducted in mountain ecosystems are rising as key tools to measure the intraspecific response of individuals transplanted across contrasting elevations. However, a synthesis quantifying patterns of plant performance in response to changes in abiotic factors across different species and mountain ranges is still lacking.

We conducted a meta‐analysis to quantitatively summarize patterns of plant species' performance variation in response to changes in temperature and precipitation within their elevation range across multiple transplant experiment studies. We compiled a dataset obtained from 38 studies and 49 vascular plant species in total addressing intraspecific performance variation in terms of survival, germination, biomass, height, number of vegetative organs, number of reproductive units, SLA and leaf size. We both compared pairs of transplanted individuals to those growing at their site of origin (‘away vs. home’) and to the local individuals found at the site of transplant (‘foreign vs. local’).

Overall, individuals transplanted downward showed larger biomass and height compared to their site of origin but failed to adjust these traits and survival to that of local individuals. Individuals transplanted upward adjusted their traits by decreasing plant growth and number of reproductive units to that of local individuals but showed lower survival. Importantly, changes in survival, biomass, height, leaf size, number of vegetative organs and reproductive units increased linearly with the difference in mean annual temperature between site of transplant and site of origin in the ‘away vs. home’ comparison. Conversely, changes in biomass, leaf size, number of vegetative organs and reproductive units increased with mean annual precipitation difference between sites in the ‘foreign vs. local’ comparison.

Synthesis. We detected common trends in survival and intraspecific trait variation across different species and transplant experiments conducted along elevational gradients. Because plasticity and adaptation play a crucial role in plant shift, establishment and persistence under non‐local environmental conditions, our meta‐analysis contributes to better understand how rapid plant shifts are constrained by climatic conditions within species' elevational range.

Authors: Morgan Dominic P , Muscatello David , Travaglia Joanne , Hayen Andrew 
Published: March 2020

AbstractObjectiveThis study aims to present overall survival rates to hospital discharge for out‐of‐hospital cardiac arrest (OHCA) in Tasmania and to identify predictors of survival.MethodsA retrospective observational cohort study was undertaken from 1 January 2010 to 31 December 2014. A probabilistically linked data set was created from paramedic electronic medical records and hospital patient records. Logistic regression was used to assess factors associated with survival of OHCA.ResultsDuring the study, 2949 incidents of OHCA were reviewed and 1146 had emergency management provided, with an overall survival rate to hospital discharge of 135 (12%). A number of independent factors are associated with improved outcomes including if the initial presenting cardiac rhythm was either ventricular fibrillation or ventricular tachycardia (adjusted odds ratio [OR] 8.75, 95% confidence interval [CI] 5.15–14.89) (P < 0.0001) relative to those who were found in a non‐shockable rhythm. Another factor was age group (overall P < 0.001). Those aged 85+ years had a reduced overall survival rate (2.9%), which was lower than those <16 years of age (OR 0.37, 95% CI 0.07–1.94; adjusted OR 0.38, CI 0.03–1.00) (P < 0.001). The odds of surviving OHCA decreased by 9% for every minute defibrillation of a shockable rhythm was delayed were witnessed by a bystander (OR 0.90, 95% CI 0.85–0.95).ConclusionTime to defibrillation for witnessed arrests, other than paramedic witnessed arrest was associated with better overall survival rates than unwitnessed OHCA. Further factors such as the event being of cardiac aetiology, bystander cardio‐pulmonary resuscitation performed, initial presenting cardiac rhythm of ventricular fibrillation or ventricular tachycardia and decreasing age were all associated with increased probability of survival.

Published: March 2020

AbstractIn order to establish an efficient detection method to evaluate the formation of Amadori compounds (ACs) in food products and study the potential health effects, an ultra‐high performance liquid chromatography‐tandem mass spectrometric (UPLC‐MS/MS) method using caffeine as internal standard was developed to determine eight ACs. The detection limits ranged from 0.0179 to 0.0887 mg/L for the ACs. The accuracy of the method was tested through measuring recovery of the spiked samples that varied from 81.90 ± 2.98% to 108.74 ± 2.34%. This method was further applied to detect ACs in 10 food products. Results showed that dry fruits and vegetables were rich in ACs, the total content of ACs varied from 1.36 ± 0.26 to 3415.91 ± 147.96 mg/100 g. The total amount of ACs in tomato juice heated under vacuum condition showed significant increment (P < 0.05) in 25 min at 80 °C comparing with that under atmospheric pressure due to the rapid loss of water. Besides, the amino acid content shows positive correlation with the corresponding AC formation in Maillard reaction during food drying. After heated at fixed water activity (Aw) for 4 hr by sous‐vide process, the ACs content in tomato powder increased significantly and the antioxidant activity improved as well.Practical ApplicationResults of this study provided a valuable tool to evaluate the formation of ACs in complex dry food products, facilitated the quality control of food products. The knowledge obtained will offer useful information to food processors. The synthesized ACs would facilitate further study into the antioxidant activities and potential health effects of specified AC.
Can Emergency Physicians Accurately Rule Out a Central Cause of Vertigo Using the HINTS Examination? A Systematic Review and Meta‐analysis
Authors: Ohle Robert , Montpellier Renee‐Anne , Marchadier Virginie , Wharton Aidan , McIsaac Sarah , Anderson Mackenzie , Savage David 
Published: March 2020

AbstractIntroductionDizziness is a common complaint presented in the emergency department (ED). A subset of these patients will present with acute vestibular syndrome (AVS). AVS is a clinical syndrome defined by the presence of vertigo, nystagmus, head motion intolerance, ataxia, and nausea/vomiting. These symptoms are most often due to benign vestibular neuritis; however, they can be a sign of a dangerous central cause, i.e., vertebrobasilar stroke. The Head Impulse test, Nystagmus, Test of Skew (HINTS) examination has been proposed as a bedside test for frontline clinicians to rule out stroke in those presenting with AVS. Our objective was to assess the diagnostic accuracy of the HINTS examination to rule out a central cause of vertigo in an adult population presenting to the ED with AVS. Our aim was to assess the diagnostic accuracy when performed by emergency physicians versus neurologists.MethodsWe searched PubMed, Medline, Embase, the Cochrane database, and relevant conference abstracts from 2009 to September 2019 and performed hand searches. No restrictions for language or study type were imposed. Prospective studies with patients presenting with AVS using criterion standard of computed tomography and/or magnetic resonance imaging were selected for review. Two independent reviewers extracted data from relevant studies. Studies were combined if low clinical and statistical heterogeneity was present. Study quality was assessed using the QUADAS‐2 tool. Random effects meta‐analysis was performed using RevMan 5 and SAS 9.3.ResultsA total of five studies with 617 participants met the inclusion criteria. The mean (±SD) study length was 5.3 (±3.3) years. Prevalence of vertebrobasilar stroke ranged 9.3% to 44% (mean ± SD = 39.1% ± 17.1%). The most common diagnoses were vertebrobasilar stroke (mean ± SD = 34.8% ± 17.1%), peripheral cause (mean ± SD = 30.9% ± 16%), and intracerebral hemorrhage (mean ± SD = 2.2% ± 0.5%). The HINTS examination, when performed by neurologists, had a sensitivity of 96.7% (95% CI = 93.1% to 98.5%, I2 = 0%) and specificity of 94.8% (95% CI = 91% to 97.1%, I2 = 0%). When performed by a cohort of physicians including both emergency physicians (board certified) and neurologists (fellowship trained in neurootology or vascular neurology) the sensitivity was 83% (95% CI = 63% to 95%) and specificity was 44% (95% CI = 36% to 51%).ConclusionsThe HINTS examination, when used in isolation by emergency physicians, has not been shown to be sufficiently accurate to rule out a stroke in those presenting with AVS.
