Ecological specialization under multidimensional tradeoffs
Authors: Amado André , Campos Paulo R. A. 
Published: December 2018

AbstractAlthough tradeoffs are expected to play an essential role in shaping the diversity in a community, their effects remain relatively nebulous and notoriously difficult to assess. This is especially true when multiple tradeoffs occur simultaneously. When dealing with single tradeoffs some information can be predicted based on their curvature. Does the same happen when dealing with multiple tradeoffs? What happens if the tradeoffs have opposing curvatures? To address these issues, we develop a resource-based model that encompasses multiple tradeoffs mediated by the acquisition and processing of the resources. The model considers a spatially structured population of microbial organisms that can grow on an arbitrary number of resources, which come into the system at a constant rate and diffuse through the environment. The individuals can adopt a variety of strategies through mutation constrained by tradeoffs, which renders the model adaptive. We assess population sizes and levels of ecological specialization. We find that when multiple tradeoffs are considered the classical intuition developed for single tradeoffs does not hold. The outcome can depend significantly not only on the curvature of the tradeoffs but also on resource availability.

Published: December 2018

AbstractBuilding accurate movement decoding models from brain signals is crucial for many biomedical applications. Decoding specific movement features, such as speed and force, may provide additional useful information at the expense of increasing the complexity of the decoding problem. Recent attempts to predict movement speed and force from the electroencephalogram (EEG) achieved classification accuracy levels not better than chance, stressing the demand for more accurate prediction strategies. Thus, the aim of this study was to improve the prediction accuracy of hand movement speed and force from single-trial EEG signals recorded from healthy volunteers. A strategy based on convolutional neural networks (ConvNets) was tested, since it has previously shown good performance in the classification of EEG signals. ConvNets achieved an overall accuracy of 84% in the classification of two different levels of speed and force (4-class classification) from single-trial EEG. These results represent a substantial improvement over previously reported results, suggesting that hand movement speed and force can be accurately predicted from single-trial EEG.

Published: December 2018

AbstractMost mammalian neurons have a narrow axon, which constrains the passage of large cargoes such as autophagosomes that can be larger than the axon diameter. Radial axonal expansion must therefore occur to ensure efficient axonal trafficking. In this study we consistently find that the trafficking speed of various large axonal cargoes is significantly slower than that of small ones, and reveal that the transit of diverse-sized cargoes causes an acute, albeit transient axonal radial expansion, which is immediately restored by constitutive contractility. Using live super-resolution microscopy, we demonstrate that actomyosin-II controls axonal radial contractility and local expansion, and that NM-II filaments associate with periodic F-actin rings via their head domains. Pharmacological inhibition of NM-II activity, significantly increases axon diameter by detaching the NM-II from F-actin, and impacts the trafficking speed, directionality, and overall efficiency of long-range retrograde trafficking. Consequently, prolonged disruption of NM-II activity leads to disruption of periodic actin rings and formation of focal axonal swellings, a hallmark of axonal degeneration.SummaryAxonal radial contractility and local expansion control the retrograde trafficking of large cargoes. The periodic actomyosin-II network comprises of NM-II filaments and F-actin rings. Loss of actomyosin-II-mediated radial contractility causes defects in axonal trafficking and stability, leading to degeneration.
Theoretical and experimental investigations on corrosion control of mild steel in hydrochloric acid solution by 4-aminothiophenol
Authors: Yildiz Resit , Dogru Mert Basak 
Published: December 2018

PurposeThis paper aims to study inhibitory effect of 4-aminothiophenol on the corrosion of mild steel (MS) in 0.5 M HCl.Design/methodology/approachIn this study, electrochemical experiments, quantum chemical calculations, potentiodynamic measurements, linear polarization resistance and scanning electron microscopy were used.FindingsThe experimental results suggest that this compound is efficient corrosion inhibitor and the inhibition efficiencies increase with increasing their (from 0.5 to 10.0 mM.) concentrations. This reveals that inhibitive actions of inhibitors were mainly due to adsorption on mild steel surface. The adsorption of these inhibitors was found to obey Langmuir adsorption model. The computed quantum chemical features show good correlation with empirical inhibition efficiencies.Originality/valueThe 4-aminothiophenol is suitable inhibitor for application in closed-circuit systems against corrosion. The study is original and has great impact in industrial area. The obtained theoretical results have been adapted with the experimental data.
Effect of pH and NaCl concentration on the hydrogen evolution reaction of X60 steel
Authors: Li Zili , Yang Chao , Cui Gan , Zhang Shouxin , Zhang Chengbin 
Published: December 2018

Purpose
When hydrogen evolution reaction occurs on a metal surface, on the one hand, the generated hydrogen atom may penetrate into the metal that causes the hydrogen embrittlement failure of materials; on the other hand, the hydrogen generation may increase the local pressure in the coating and cause coating blistering. The purpose of this study is to study the effect of NaCl concentration and pH on hydrogen evolution reaction of X60 steel.

Design/methodology/approach
A cathodic polarization curve 257E-2V vs OCP and EIS was obtained by conventional three-electrode system in different NaCl concentrations, 257E3.5 and pH. Second, various parameters such as hydrogen evolution, over-potential current–density polarization resistance and capacitance of double electric layer were obtained based on fitting of the experimental data. Finally, the reaction mechanism was determined by Tafel curves.

Findings
It was concluded that in different NaCl concentrations, diffusion layer induced by concentration polarization affects the diffusion process of H+ ions, which makes over-potential increase. Under great effect of concentration polarization, the reaction is different in acid and alkaline environments, and the dielectric layer shows the characteristic of meta-alkaline adsorption, which makes difference in mechanism.

Originality/value
This research not only has theoretical significance but also gains utilization prospect. Ultimately, this research could be applied to clear hydrogen evolution process and protect long-distance pipeline against delamination.
Aircraft runway excursion features: a multiple correspondence analysis
Authors: Distefano Natalia , Leonardi Salvatore 
Published: December 2018

Purpose
The risk of aircraft runway excursion, dependent on multiple factors, is related to operating conditions. The purpose of this paper is to identify the correspondence between features belonging to different aspects that occur in runway excursion events, distinguishing between take-off and landing phases.

Design/methodology/approach
To define the correspondence between the characteristic features of runway excursions, this study has applied multiple correspondence analysis (MCA). MCA is used to represent and model data sets as “clouds” of points in a multi-dimensional Euclidean space. There are five variables used in MCA: geographical region, potential cause, aircraft class, flight nature and aircraft damages. For the purpose of this research, the database contains only runway excursion accidents that took place between 2006 and 2016 among all categories of aircraft in all world regions. The events contained in the database were analyzed by separating those that occurred during take-off and those that occurred during landing.

Findings
With this method, this study identified a few particularly interesting variable combinations. Generally, the consequence of an aircraft runway excursion is substantial aircraft damage. Also, the most common cause of runway excursion during take-off is aircraft system faults, while during landing, it is weather conditions. Furthermore, the destruction of an aircraft is a result of a runway excursion due to bad weather conditions, both during take-off and landing.

Practical implications
The results of this study can be used by a broad range of civil aviation organizations for runway risk assessment and to select the most effective safety countermeasures for runway excursions.

Originality/value
The authors believe this study is original, especially for the statistical analysis method used.
The nature of crowdfunding in China: initial evidence
Authors: Huang Zaiyu , Chiu Candy Lim , Mo Sha , Marjerison Rob 
Published: December 2018

PurposeThe purpose of this paper is to develop initial evidence about the nature and features of crowdfunding in China, given it is largely unregulated regulatory frameworks.Design/methodology/approachThe paper used extensive desk research using data collected from the public and private sectors, after which the data was analyzed parallel to existing academic literature, that is, institutional context by Brutonet al.(2014). This paper uncovered patterns of development, profiling crowdfunding platforms, examining the regulatory landscape and providing antecedents of successful crowdfunding projects in China.FindingsWhen the traditional financial markets are hard to reach, micro, small and medium enterprises (MSMEs) were starved for capital. Crowdfunding can play a major role in funding and risk sharing. It is an innovative and dynamic vehicle for MSMEs as well as enthusiastic investors in China. Since its initial introduction to China in 2009, crowdfunding has gained substantial popularity in a relatively short period. Currently, there is still not an identifiable guideline on how to delineate the significance of the crowdfunding platform. The development of crowdfunding in China faces a few unresolved key issues. As researchers exploring this phenomenon in new ways, crowdfunding platforms can be enhanced in a manner that benefits the capital seeker, investors and society as a whole.Originality/valueThere is a dearth of information on start-up crowdfunding in Asia. With little data available to analyze, so this paper hopes to contribute to knowledge and provide valuable information to researchers and industry representations. Crowdfunding represents a potentially disruptive change in the way that new ventures are funded. This paper represents an initial analysis in the study of new ventures in China. Finally, the authors provide recommendations for entrepreneurs, investors and policymakers as well as researchers and practitioners with suggestions about yet unexplored avenues of research.
Who are the future seaweed consumers in a Western society? Insights from Australia
Authors: Birch Dawn , Skallerud Kåre , Paul Nicholas A. 
Published: December 2018

PurposeThe purpose of this paper is to profile the consumers who are likely to eat seaweed products in Australia.Design/methodology/approachThe study was conducted as an online survey among 521 Australian consumers. Binary logistic regression modelling was used to profile the consumers.FindingsThe paper identifies education, familiarity, food neophobia (FNeo), symbolic value of food consumption, health consciousness, as well as snacking behaviour as significant predictors of likelihood to eat seaweed products. Consumers with a university degree (i.e. undergraduates and postgraduates) are four times more likely to eat seaweed products, and those familiar with seaweed products have a 7.6 higher likelihood to eat seaweed products. FNeo makes the largest contribution to the consumer’s likelihood to eat seaweed. A one unit increase in the FNeo score is associated with a 77 per cent decrease in the predicted odds of eating seaweed products in the next 12 months. The symbolic value of food consumption and health consciousness both doubled the likelihood of eating seaweed products. Snacking behaviour increases the likelihood by 185 per cent. The study reveals that early adopters of seaweed food products in western societies are people with higher educational levels, who are adventurous in their food choices and perceive seaweed consumption to have symbolic value. They are also health conscious “snackers”.Originality/valueThis study is one of the first attempts to provide insights about consumption of seaweed products; and also reveals the consumer groups in western societies that are most likely to eat seaweed products and who can be targeted as potential early adopters.

Authors: Badruddin Irfan Anjum 
Published: December 2018

Purpose
The purpose of this paper is to investigate the heat transfer in an arbitrary cavity filled with porous medium. The geometry of the cavity is such that an isothermal heating source is placed centrally at the bottom of the cavity. The height and width of the heating source is varied to analyses its effect on the heat transfer characteristics. The investigation is carried out for three different cases of outer boundary conditions such as two outside vertical walls being maintained at cold temperature To, two vertical and top horizontal surface being heated to. To and the third case with top surface kept at To but other surfaces being adiabatic.

Design/methodology/approach
Finite element method is used to solve the governing equations.

Findings
It is observed that the cavity exhibits unique heat transfer behavior as compared to regular cavity. The cases of boundary conditions are found to affect the heat transfer rate in the porous cavity.

Originality/value
This is original work representing the heat transfer in irregular porous cavity with various boundary conditions. This work is neither being published nor under review in any other journal.
Stagnation-point flow and heat transfer of upper-convected Oldroyd-B MHD nanofluid with Cattaneo–Christov double-diffusion model
Authors: Bai Yu , Xie Bo , Zhang Yan , Cao Yingjian , Shen Yunpeng 
Published: December 2018

Purpose
The purpose of this paper is to investigate the two-dimensional stagnation-point flow, heat and mass transfer of an incompressible upper-convected Oldroyd-B MHD nanofluid over a stretching surface with convective heat transfer boundary condition in the presence of thermal radiation, Brownian motion, thermophoresis and chemical reaction. The process of heat and mass transfer based on Cattaneo–Christov double-diffusion model is studied, which can characterize the features of thermal and concentration relaxations factors.

Design/methodology/approach
The governing equations are developed and similarly transformed into a set of ordinary differential equations, which are solved by a newly approximate analytical method combining the double-parameter transformation expansion method with the base function method (DPTEM-BF).

Findings
An interesting phenomenon can be found that all the velocity profiles first enhance up to a maximal value and then gradually drop to the value of the stagnation parameter, which indicates the viscoelastic memory characteristic of Oldroyd-B fluid. Moreover, it is revealed that the thickness of the thermal and mass boundary layer is increasing with larger values of thermal and concentration relaxation parameters, which indicates that Cattaneo–Christov double-diffusion model restricts the heat and mass transfer comparing with classical Fourier’s law and Fick’s law.

Originality/value
This paper focuses on stagnation-point flow, heat and mass transfer combining the constitutive relation of upper-convected Oldroyd-B fluid and Cattaneo–Christov double diffusion model.
Capital endowment and race to the bottom in a federation
Authors: Chel Moumita , Mukherjee Vivekananda 
Published: December 2018

PurposeThis paper aims to analyse the phenomenon of race to the bottom in a federation and provides answer to the question why developing countries are more prone to race to the bottom competition than developed countries.Design/methodology/approachThe paper considers a two-stage game where, in the first stage, two regional governments in a federation choose tax rate on mobile capital employed in its own region by maximising its regional per capita income, and in the second stage, a representative firm chooses capital and labour employment in the two regions by maximising total profit. As capital is mobile across regions, tax policy chosen by any region affects other region. From strategic interaction between the regional governments, the authors derive Nash equilibrium tax rates. Comparing Nash equilibrium with Pareto optimum outcome, race to the bottom is characterised.FindingsThe paper finds that federations with poorer endowment of capital are more prone to the race to the bottom outcome. The result is robust to the introduction of different types of asymmetries between the regions and a centrally executed revenue equalisation scheme. Whilst it hints at the fact that capital accumulation can naturally solve the race to the bottom problem, it identifies the presence of an equalisation scheme and equity concern at the regions to weaken the impact of capital accumulation in achieving such an outcome.Originality/valueThe role of capital endowment in the race to the bottom literature in fiscal federalism has previously been ignored. This has serious implications for developing countries like China and India where states compete with each other for attracting private capital in their own jurisdictions.
Effects of service experience on customer responses to a hotel chain
Authors: Bravo Rafael , Martinez Eva , Pina Jose M. 
Published: December 2018

PurposeThis paper aims to analyse customer experience in a hotel and its impact on customer attitudes to both the individual hotel and the hotel chain. Specifically, the study focuses on the effects of service perceptions on emotions, satisfaction, attitude to hotel chain, intention to return, scepticism towards negative information and Word of Mouth (WOM).Design/methodology/approachAn empirical study was carried out on a sample of 300 individuals. Data were analysed through structural equation modelling.FindingsService perceptions and emotions elicited by an individual hotel influence the customer response towards the hotel chain. Among all the outcomes considered, the strongest effects are found on WOM.Originality/valueThis paper develops and empirically tests an original model that integrates the customer experience in an individual hotel and the customer response to the hotel chain. This model includes variables that have recently been considered in the literature, such as scepticism towards negative information, in combination with more traditional outcomes such as intention to return or WOM.
Evaluation of a new recovery college: delivering health outcomes and cost efficiencies via an educational approach
Authors: Kay Katie , Edgley George 
Published: December 2018

Purpose
The purpose of this paper is to evaluate cost efficiencies and health outcomes after one academic year of course delivery, in a recovery college.

Design/methodology/approach
The paper used service evaluation and review of data.

Findings
There is significant impact on health outcomes when standardised measures of Patient Activation Measure and Warwick–Edinburgh Mental Wellbeing Scale were completed pre- and post-intervention, with indications of possible financial efficiencies identified within secondary care mental health pathways.

Research limitations/implications
The current evaluation sample is only representative of community mental health populations rather than broader communities. However, indications are that the model is effective from a wider public health perspective (early intervention/prevention) in producing significant health outcomes in terms of improved wellbeing and increased levels of activation/self-management. More in-depth research collaboration with an academic institution is now required.

Practical implications
There is an implication that the recovery college needs to be fully embedded within the mental health pathway as part of the core offer. This would require significant service redesign and culture change within the organisation.

Social implications
There is a need to continue to work with other statutory service providers, key stakeholders, voluntary and community sectors to embed the college with wider public health services and ensure a holistic approach across local communities and the whole health pathway.

Originality/value
Although the model is based on the widely recognised national recovery college model, it has moved away from the usual boundaries of access only being for those attached to secondary care mental health services to a more holistic and integrative approach of offering access to the whole population. Social value is indicated in the ownership and co-production of the model by the collaboration of student expertise, experts by experience and experts by expertise. The co-produced integrated volunteering and work pathway offers positive and cost-efficient health outcomes from a co-designed and co-delivered educational approach.
A study on the effectiveness of aesthetically appealing print recruitment advertisement
Authors: Ganesan Muruganantham , George Esther Princess 
Published: December 2018

PurposeThe purpose of this paper is to assess the nature of intervention of job seeker’s perception of organizational attraction and attitude toward ad and organization in the application intention produced by aesthetics of print job ads.Design/methodology/approachAn aesthetically appealing faculty-opening job advertisement was used as stimuli and around 250 responses to an administered questionnaire were collected from among job seekers in the academic domain. Partial least square structural equation modeling (PLS-SEM) was used to test the hypothesis.FindingsAccording to the results of the study, aesthetic features of print recruitment ad, even though insignificant in directly inducing job seeker intention to apply, significantly enhanced their organizational attraction and attitudes, and thereby, their application intention. Therefore, job seeker’s perception of organizational attractiveness and attitude were found to full mediate this relationship, regardless of the job seekers’ degree of familiarity with the organization.Practical implicationsThis study encourages recruiters in the academic job sectors to design and administer aesthetically appealing job advertisements to maximize the high talent pool of applicants from which to choose.Originality/valueThis study is the first of its kind in the Indian context in terms of print recruitment advertising. This study is also original in reporting organizational attraction and attitude towards ad and organization as mediators of application intention produced by ad aesthetics.
