A Multiscale and Comparative Model for Receptor Binding of 2019 Novel Coronavirus and the Implication of its Life Cycle in Host Cells
Authors: Su Zhaoqian , Wu Yinghao 
Published: February 2020

ABSTRACTThe respiratory syndrome caused by a new type of coronavirus has been emerging from China and caused more than one million death globally since December 2019. This new virus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses the same receptor called Angiotensin-converting enzyme 2 (ACE2) to attack humans as the coronavirus that caused the severe acute respiratory syndrome (SARS) seventeen years ago. Both viruses recognize ACE2 through the spike proteins (S-protein) on their surfaces. It was found that the S-protein from the SARS coronavirus (SARS-CoV) bind stronger to ACE2 than SARS-CoV-2. However, function of a bio-system is often under kinetic, rather than thermodynamic, control. To address this issue, we constructed a structural model for complex formed between ACE2 and the S-protein from SARS-CoV-2, so that the rate of their association can be estimated and compared with the binding of S-protein from SARS-CoV by a multiscale simulation method. Our simulation results suggest that the association of new virus to the receptor is slower than SARS, which is consistent with the experimental data obtained very recently. We further integrated this difference of association rate between virus and receptor into a mathematical model which describes the life cycle of virus in host cells and its interplay with the innate immune system. Interestingly, we found that the slower association between virus and receptor can result in longer incubation period, while still maintaining a relatively higher level of viral concentration in human body. Our computational study therefore provides, from the molecular level, one possible explanation that this new pandemic by far spread much faster than SARS.
The fish body functions as an airfoil: surface pressures generate thrust during carangiform locomotion
Authors: Lucas Kelsey N. , Lauder George V. , Tytell Eric D. 
Published: February 2020

AbstractThe anterior body of many fishes is shaped like an airfoil turned on its side. With an oscillating angle to the swimming direction, such an airfoil experiences negative pressure due to both its shape and pitching movements. This negative pressure acts as thrust forces on the anterior body. Here, we apply a high-resolution, pressure-based approach to describe how two fishes, bluegill sunfish (Lepomis macrochirusRafinesque) and brook trout (Salvelinus fontinalisMitchill), swimming in the carangiform mode, the most common fish swimming mode, generate thrust on their anterior bodies using leading-edge suction mechanics, much like an airfoil. These mechanics contrast with those previously reported in lampreys – anguilliform swimmers – which produce thrust with negative pressure but do so through undulatory mechanics. The thrust produced on the anterior body of these carangiform swimmers through negative pressure comprises 28% of the total thrust produced over the body and caudal fin, substantially decreasing the net drag on the anterior body. On the posterior region, subtle differences in body shape and kinematics allow trout to produce more thrust than bluegill, suggesting that they may swim more effectively. Despite the large phylogenetic distance between these species, and differences near the tail, the pressure profiles around the anterior body are similar. We suggest that such airfoil-like mechanics are highly efficient, because they require very little movement and therefore relatively little active muscular energy, and may be used by a wide range of fishes since many species have appropriately-shaped bodies.Significance StatementMany fishes have bodies shaped like a low-drag airfoil, with a rounded leading edge and a smoothly tapered trailing region, and move like an airfoil pitching at a small angle. This shape reduces drag but its significance for thrust production by fishes has not been investigated experimentally. By quantifying body surface pressures and forces during swimming, we find that the anterior body shape and movement allows fishes to produce thrust in the same way as an oscillating airfoil. This work helps us to understand how the streamlined body shape of fishes contributes, not only to reducing drag, but also directly to propulsion, and, by quantitatively linking form and function, leads to a more complete understanding fish evolution and ecology.

Authors: Jiang Cheng , Yang Ying , Cheng Xuequn , Zhao Jinbin , Li Xiaogang 
Published: February 2020

PurposeThis study aims to study the effect of Sn on the corrosion behavior of weathering steel (WS) in a simulated tropical marine atmosphere.Design/methodology/approachIndoor alternate immersion tests, electrochemical measurements and real-time current-monitoring technology based on the galvanic corrosion principle were used and the scanning electron microscope, X-ray diffraction, X-ray photoelectron spectroscopy and electron probe microanalyzer were used to analyze the morphology and component of the rust layer.FindingsThe results indicated that Sn has a positive influence on the corrosion process. Sn participated in the composition of the rust layer in the form of SnO2and is enriched in the inner rust layer. SnO2participated in the coprecipitation process with iron oxides and oxyhydroxides, which promoted further transformation ofγ-FeOOH toα-FeOOH. As a result, the rust layer of Sn-containing steel was continuous, compact and effectively blocked the invasion of aggressive Cl−. Therefore, the additive of Sn enhanced the corrosion resistance of WS in a simulated tropical marine atmosphere.Originality/valueThe corrosion behaviors of WS were researched by the real-time current-monitoring technology which was rarely used.

Authors: Gaviria-Marin Magaly , Cruz-Cázares Claudio 
Published: February 2020

PurposeThe purpose of this article is to analyze the influence of the diversity of information and the use of Web 2.0 applications on the web positioning of online business information providers.Design/methodology/approachA total of 203 online business information provider websites were selected using three search engines (Google, Yahoo and Bing). This information was encoded to develop two logistic regression models.FindingsThe results suggest that the knowledge offered and the resources used to transfer this knowledge play important roles in the web positioning of online business information providers. This study found that entrepreneurs mainly seek technological knowledge, and to acquire it, they use various Web 2.0 applications that do not necessarily include social networks.Practical implicationsThis article presents a novel proposal to analyze how knowledge diversity and Web 2.0 applications influence the web rankings of websites that offer information and knowledge for established or new, small and medium enterprises.Originality/valueThis article is novel in that it links the theory of knowledge dissemination with the technologies of the Internet (websites, Web 2.0 applications) and provides evidence of diverse sources of online information that are potentially useful for the entrepreneur of the twentieth century.

Published: February 2020

PurposeThe purpose of this paper is to investigate the effects of choice on the development and maintenance of a fruit consumption behaviour and if behaviour change was underpinned by habit strength.Design/methodology/approachA 2×2×3 mixed model experimental design was used. The independent variables were pictorial cue and fruit consumption manipulated on two levels: choice and no choice, across three-time points: baseline, post-intervention (after two weeks) and follow-up (one week later). Participants (n=166) completed demographics, the self-report habit index and fruit intake at all three-time points.FindingsAll participants showed significant increases in fruit consumption and habit strength at post-intervention and follow-up. However, participants provided neither choice of cue nor fruit showed a significant decrease in consumption at follow-up.Practical implicationsFruit consumption can be significantly increased with a relatively simple intervention; choice seems to have an effect on behaviour maintenance, providing no choice negatively effects behaviour maintenance post-intervention. This may inform future interventions designed to increase fruit and vegetable consumption.Originality/valueThe intervention that the authors designed and implemented in the current study is the first of its kind, where choice was manipulated in two different ways and behaviour was changed with a simple environmental cue intervention.
Assessing lean implementation and benefits within Indian automotive component manufacturing SMEs
Authors: Sahoo Saumyaranjan 
Published: February 2020

PurposeThe purpose of this paper is to investigate the status of lean manufacturing in Indian automotive sector, component manufacturing industries in terms of lean adoption, benefits, motivation, and challenges of implementing lean manufacturing practices.Design/methodology/approachThe research objectives were achieved by conducting a qualitative multicase study approach. Fourteen Indian automotive component manufacturing small and medium-sized enterprises (SMEs) were chosen based on their different product offerings as well as differing approaches to the introduction and implementation of lean initiatives. Data were collected through in-depth, semistructured interviews supported by shop-floor observations.FindingsThe findings from the present study suggest that some of the participating automotive component manufacturing SMEs have a relatively good understanding of lean concepts and philosophy. However, there is room for further improvement for most SMEs. Major top five lean practices being implemented were found to be cellular manufacturing, total productive maintenance, 5S, work standardization, and quality management practices. Also, leadership and organizational culture were found to be crucial factors for the success of lean manufacturing.Research limitations/implicationsThe fact that the data collected for the research study is based on subjective business evidence obtained from company representatives comprises the main limitation of the present study. So, the results should be considered with caution, as far as the lean adoption in Indian automotive component manufacturing sector is concerned.Practical implicationsBased on the present study, suggestions can be made regarding the successful adoption of lean principles, not only for the participating SMEs but also for the whole of the automotive component manufacturing sector. More specifically, by determining the strength and weakness of automotive component manufacturing SME's effort to adopt lean, suitable managerial initiatives can be undertaken by these companies as well as the whole sector to fully adopt lean and derive the respective benefits.Originality/valueThis paper explores the status of lean adoption in Indian automotive component manufacturing SMEs. Considering the unique characteristics of the automotive component manufacturing industry, the present research would be helpful for making strategies to implement lean in automotive component manufacturing industry setups.
When and why skill variety influences employee job crafting
Authors: Li Jie , Sekiguchi Tomoki , Qi Jipeng 
Published: February 2020

PurposeThe literature on job crafting has paid scant attention to the role of skill variety, one dimension of job characteristics, as a predictor of employee job crafting. By integrating regulatory focus and social exchange perspectives with job crafting literature, the authors investigate how skill variety promotes employee job crafting and the moderating roles of employee's promotion focus and procedural justice climate.Design/methodology/approachThe authors conducted two questionnaire surveys, one with a sample of 205 employees from a variety of organizations in China, and the other one with a sample of 265 employees within 44 work groups at a state-owned enterprise in China, to examine the hypotheses.FindingsResults suggest that a high level of skill variety within a job promotes employee job crafting, that such an effect is stronger when the employee's promotion focus is high rather than low, and that procedural justice climate mitigates the negative influence of a low level of promotion focus.Originality/valueThe authors' findings suggest that both self-regulatory and social exchange mechanisms play a critical role in promoting employee job crafting when individuals are engaged in jobs that entail a high level of skill variety.
Numerical heat flow visualization analysis on enhanced thermal processing for various shapes of containers during thermal convection
Authors: Lukose Leo , Basak Tanmay 
Published: February 2020

PurposeThe purpose of this paper is to study thermal (natural) convection in nine different containers involving the same area (area= 1 sq. unit) and identical heat input at the bottom wall (isothermal/sinusoidal heating). Containers are categorized into three classes based on geometric conﬁgurations [Class 1 (square, tilted square and parallelogram), Class 2 (trapezoidal type 1, trapezoidal type 2 and triangle) and Class 3 (convex, concave and triangle with curved hypotenuse)].Design/methodology/approachThe governing equations are solved by using the Galerkin ﬁnite element method for various processing fluids (Pr= 0.025 and 155) and Rayleigh numbers (103 ≤ Ra≤ 105) involving nine different containers. Finite element-based heat flow visualization via heatlines has been adopted to study heat distribution at various sections. Average Nusselt number at the bottom wall (Nub¯) and spatially average temperature (θ^) have also been calculated based on ﬁnite element basis functions.FindingsBased on enhanced heating criteria (higherNub¯and higher θ^), the containers are preferred as follows, Class 1: square and parallelogram, Class 2: trapezoidal type 1 and trapezoidal type 2 and Class 3: convex (higher θ^) and concave (higherNub¯).Practical implicationsThe comparison of heat flow distributions and isotherms in nine containers gives a clear perspective for choosing appropriate containers at various process parameters (PrandRa). The results for current work may be useful to obtain enhancement of the thermal processing rate in various process industries.Originality/valueHeatlines provide a complete understanding of heat flow path and heat distribution within nine containers. Various cold zones and thermal mixing zones have been highlighted and these zones are found to be altered with various shapes of containers. The importance of containers with curved walls for enhanced thermal processing rate is clearly established.

Published: February 2020

PurposeIncident reporting systems are commonly deployed in healthcare but resulting datasets are largely warehoused. This study explores if intelligence from such datasets could be used to improve quality, efficiency, and safety.Design/methodology/approachIncident reporting data recorded in one NHS acute Trust was mined for insight (n = 133,893 April 2005–July 2016 across 201 fields, 26,912,493 items). An a priori dataset was overlaid consisting of staffing, vital signs, and national safety indicators such as falls. Analysis was primarily nonlinear statistical approaches using Mathematica V11.FindingsThe organization developed a deeper understanding of the use of incident reporting systems both in terms of usability and possible reflection of culture. Signals emerged which focused areas of improvement or risk. An example of this is a deeper understanding of the timing and staffing levels associated with falls. Insight into the nature and grading of reporting was also gained.Practical implicationsHealthcare incident reporting data is underused and with a small amount of analysis can provide real insight and application to patient safety.Originality/valueThis study shows that insight can be gained by mining incident reporting datasets, particularly when integrated with other routinely collected data.
Colorectal cancer screening uptake among US Latino subgroups
Authors: Barrett Benjamin W. , Durden T. Elizabeth 
Published: February 2020

Purpose
The purpose of this paper is to study the colorectal cancer (CRC) screening practices of Latinos in the USA, a traditionally disadvantaged group regarding health, while operating within the theoretical lens of segmented acculturation. Differential acculturation experiences influence migrant health and healthcare access, including CRC screening.

Design/methodology/approach
Latinos are categorized into subgroups and are referenced against non-Latino whites and non-Latino blacks. Descriptive statistics and binomial logistic regression models are used to analyze the data from the 2008 and 2010–2014 National Health Interview Survey.

Findings
Latinos and respondents born outside of the non-territorial USA exhibit disparities in CRC screening participation. Screening discrepancies are not uniform across Latino subgroups, reflecting the importance of a segmented acculturation theoretical lens.

Practical implications
A discrepancy exists in CRC screening utilization among the largest minority population in the USA. These inconsistencies among US Latinos must be addressed directly to avoid serious health consequences in a large and growing population.

Originality/value
Interventions should be tailored to address the unique situational contexts of Latino subgroups suffering the health disparities. These distinct contexts are only elucidated through the use of a theoretical lens of segmented acculturation in studies of Latino health, which explicitly considers the historical and contemporary social forces acting upon the subgroups. This study extends beyond individual-level exposures to provide a more holistic view of the health behaviors and outcomes among Latino subgroups in the USA. Insight gained from this study is invaluable to improving the health of these traditionally disadvantaged groups.
Quality management for microenterprises and start-ups: is the ISO 9001 suitable?
Authors: Klute-Wenig Sandra , Refflinghaus Robert 
Published: February 2020

Purpose
Quality management systems (QMSs) are well established in multinationals and small-and-medium enterprises (SMEs). For establishing and improving these systems, a variety of guidelines have been established. Furthermore, there are software tools allowing a self-assessment of the current state of the implemented systems. However, these approaches are not appropriate for microenterprises and start-ups as their processes are rather informal or not yet specified. Moreover, these companies are often in a phase of strong growth and have only one person in charge; hence, they face the difficulty to decide if and how a QMS should be implemented. The purpose of this study is to report a first guideline for implementation of a QMS for microenterprises and start-ups.

Design/methodology/approach
The first step comprises a definition of microenterprises and start-ups and an analysis of their specific characteristics. An overview of the DIN EN ISO 9001:2015 and its requirements is given below. Next, the relevant requirements that can be implemented in microenterprises and start-ups are analyzed. Accordingly, a guideline for decision-making is developed to examine if an application of the analyzed standard is useful or necessary for these companies. Moreover, the guideline illustrates how the requirements can be implemented.

Findings
A literature review, an analysis of the DIN EN ISO 9001:2015, and of microenterprises and start-ups have been carried out. Thus, the need to decide whether to implement a QMS and assistance for the implementation process has been revealed to be essential for the companies that were considered. The literature mostly deals with implementing a quality and/or project management system in multinationals and SMEs but not for very small companies. Furthermore, the practical examples have shown that microenterprises face difficulties when choosing and implementing a QMS; thus, a practical implementation guideline for these companies is lacking.

Originality/value
Although there is a lot of research dealing with quality management (QM) in SMEs, research about QM in microenterprises and start-ups is scarce. This paper offers a first approach for a guideline of implementing an appropriate QMS and possibly an additional or alternative project management system in microenterprises and start-ups. This should facilitate the process of deciding if and how to implement an adequate management system for such companies.
Sociomaterial practices for value co-creation in the sharing economy
Authors: Du Peng , Chou Hsin-Hui 
Published: February 2020

PurposeThe purpose of this paper is to address the research question of how human actors and technology interact together in practices in the context of a sharing economy. The theoretical foundation of this paper is based on the existing literature about the sharing economy and studies that have been carried out examining value co-creation and sociomateriality.Design/methodology/approachThis paper adopts a qualitative case study method for the empirical investigation. Using theoretical sampling, Xbed, an internet, unmanned and self-service hotel platform based in Guangzhou, China, was chosen for the empirical investigation. The case was built on multiple sources of data, including archival materials, on-site fieldwork and in-depth interviews. Then, the case was interpreted based on a number of theoretical concepts, with a particular emphasis on the sociomaterial perspective.FindingsThis paper shows how human actors and technology interact with one another in a number of interrelated ways, which collectively result in the value co-creation necessary for creating a sharing economy. The authors have found that various forms of sociomateriality (the intersection between technology, work and organization) play a key role in co-creation and that interactions between these sociomaterial assemblages (assemblage-to-assemblage (A2A)) drive the development of a sharing economy. These sociomaterial assemblages have dynamic and evolving characteristics.Practical implicationsThe authors argue that the key to the success of a sharing economy lies in how to engage participating actors with material entities (e.g. technology applications) to form action-enabling sociomaterial assemblages, as well as in determining how these assemblages can be systematically arranged to collectively form a larger assemblage. We suggest that managers need to conceive how relations between the social and the material realms can be structured by adopting a service logic that aims to help the beneficiary function better. The authors also suggest that managers have to consider what assemblages are necessary and how they are connected, to construct a full access-based service.Originality/valueThis paper conceptualizes the sharing economy as a system of value co-creation practices and empirically examines such practices from a sociomaterial perspective. This paper adopts the concept of sociomaterial assemblages to investigate sharing practices, through which the knowledge of the role of technology in the development of a sharing economy is enhanced. This paper also expands the knowledge of service-dominant logic by using a microfoundation perspective to look at the value co-creation that emerges as a result of the interaction between sociomaterial assemblages. These assemblages also act as constitutive elements of a service ecosystem.
