Published: August 2019

AbstractAntibiotic resistance is a global threat for public health. It is widely acknowledged that antibiotics at sub-inhibitory concentrations are important in disseminating antibiotic resistance via horizontal gene transfer. While there is high use of non-antibiotic human-targeted pharmaceuticals in our societies, the potential contribution of these on the spread of antibiotic resistance has been overlooked so far. Here, we report that commonly consumed non-antibiotic pharmaceuticals, including nonsteroidal anti-inflammatories (ibuprofen, naproxen, diclofenac), a lipid-lowering drug (gemfibrozil), and a β-blocker (propanolol), at clinically and environmentally relevant concentrations, significantly accelerated the conjugation of plasmid-borne antibiotic resistance genes. We looked at the response to these drugs by the bacteria involved in the gene transfer through various analyses that included monitoring reactive oxygen species (ROS) and cell membrane permeability by flow cytometry, cell arrangement, and whole-genome RNA and protein sequencing. We found the enhanced conjugation correlated well with increased production of ROS and cell membrane permeability. We also detected closer cell-to-cell contact and upregulated conjugal genes. Additionally, these non-antibiotic pharmaceuticals caused the bacteria to have responses similar to those detected when exposed to antibiotics, such as inducing the SOS response, and enhancing efflux pumps. The findings advance our understanding of the bacterial transfer of antibiotic resistance genes, and importantly emphasize concerns of non-antibiotic human-targeted pharmaceuticals for enhancing the spread of antibiotic resistance.
PSS: An enabling QTY server for designing water-soluble α-helical transmembrane proteins
Authors: Tao Fei , Tang Hongzhi , Zhang Shuguang , Xu Ping 
Published: August 2019

ABSTRACTMembrane proteins, especially the α-helical ones such as G-protein coupled receptors (GPCRs), are considered extremely important owing to their significant biological roles. However, their expression and purification pose difficulties because of their poor solubility in water, which seriously impedes research progress in this field. Recently, QTY method, a revolutionary code-based protein engineering approach, was developed for the purpose of producing soluble transmembrane proteins. Here we describe a web server built for QTY design and certain analyses related to it (pss.sjtu.edu.cn). Typically, the Simple Design model is expected to take only 2-4 min, and the Library Design 2-5 h, of computer time, depending on target protein size and the number of transmembrane helices. Further, we describe a protocol for using the server with both Simple and Library Design modules. Protocols for experiments based on QTY design are also included. In summary, utilization of the web server, and associated protocols, will enable QTY-based protein-engineering to be implemented in a convenient, fast, accurate, and rational manner.

Authors: Alonso Dos Santos Manuel , Calabuig Moreno Ferran , Crespo-Hervás Josep 
Published: August 2019

Purpose
The purpose of this paper is to examine the influence of congruence (perceived and effective) and the level of visual attention towards sponsors on recall and purchase intention in sports sponsorship by applying neurophysiological measures.

Design/methodology/approach
This study is part of neuromarketing research applied to sports. The experiment entails eye tracking with 111 men and 129 women (n=24) with 24 sports posters of three different disciplines (sailing, tennis and F1), varying the congruence, the number of sponsors and the position (2×2×2). The data are analyzed via analysis of covariance and regression using ordinary least squares.

Findings
Brand recall is influenced by the number of sponsors present on the poster and by the time of fixation. Effective and perceived congruence covariance the purchase intention, but the full time of fixation on the sponsor does not. The latter only, purchase intention indirectly.

Practical implications
The results enable managers to implement better poster designs and sponsors to have objective measures of sponsorship.

Originality/value
There are few studies that analyze print media in sponsorship using neurophysiological techniques. This research is a pioneer in considering attention to sports posters to examine recall and purchase intention.
A comprehensive framework for evaluating web services composition methods
Authors: Abidi Sarra , Fakhri Myriam , Essafi Mehrez , Ben Ghazela Henda 
Published: August 2019

Purpose
Web services composition engineering (WSCE) is a big challenge because of the increasing complexity, openness and extensibility of services based on the information system (IS). In the absence of an adequate framework for IS engineering, the authors assume that the overall problem is consequently no longer easy to resolve. This paper aims to explore some of the issues underlying WSCE through a framework, which is built based on the state of the art. The proposed framework is structured around five views that mainly highlight aspects of personalization and security concerns. The main objectives of this framework are: to help understand and clarify the basics of the WSCE domain; to evaluate web services composition (WSC) methods; to analyze and compare existing personalization, secure methods and identify new research axes; and to identify the main criteria of the ongoing approach for the design of a secure IS based on personalized WSC.

Design/methodology/approach
This work develops a framework that is used as an analytical study to compare the existing WSCE methods and come up with research issues. Then, the proposed framework is considered as an abstract model for the new WSCE approach.

Findings
A set of criteria that the proposed framework should consider when developing a new approach to a secure IS based on personalized WSs composition.

Research limitations/implications
The paper has theoretical implications as the personalization and security issues provide a research roadmap toward the realization of an approach for the design of a secure IS based on personalized WSs composition.

Practical implications
As proof, the authors are interested in a web services repository of a real mall. To do this, the authors deployed the application in a cloud environment and observed the results of personalization and security concepts in WSCE.

Originality/value
None of the existing comparison frameworks has raised both personalization and security issues in WSs composition, while personalization and security must be present in the whole composition process.

Authors: Wu Jianpeng , Ma Biao , Li Heyan , Ma Chengnan 
Published: August 2019

PurposeThe purpose of this paper is to study friction and wear properties of three types of steels against paper-based friction disc, including 65Mn, 20#steel and 30CrAl, so as to obtain the appropriate working conditions for different friction materials in the transmission system.Design/methodology/approachBased on actual working conditions, pin-on-disc tests are conducted on a universal material tester. The two evaluation indexes, including average friction coefficient and variation coefficient, are introduced to analyze the different friction properties among three types of steel. Furthermore, the temperature-dependent wear pattern and wear depth are subsequently studied.FindingsThe results show that 65Mn is more suitable for working under heavy load and low velocity, but 30CrAl and 20#steel are suitable for working under light load and high velocity. Moreover, wear primarily occurs on paper-based material and peaks at about 325.Practical implicationsThis research of different materials and friction property for friction pairs is helpful to improve the performance and prolong the service life of transmission systems.Originality/valueSuitable working conditions of different friction materials are obtained, and the correlation between wear and decomposition in high temperature is verified.
Maturity as a way forward for improving organizations’ communication evaluation and measurement practices
Authors: Gilkerson Nathan David , Swenson Rebecca , Likely Fraser 
Published: August 2019

Purpose
The purpose of this paper is to propose an explication of the concept of “maturity,” as it applies to communication evaluation and measurement (E&M) practice, along with contextualization of recent maturity model adoption within academic and professional communities.

Design/methodology/approach
Drawing from previous work on maturity models within other fields, recent communication scholarship and industry practice, this paper fills a gap in the literature by offering a theoretical conceptualization of communication E&M maturity, including the construct’s core dimensions and sub-dimensions.

Findings
Communication E&M maturity is conceptualized into four essential elements: holistic approach, investment, alignment and culture. The contribution of E&M efforts is represented as the direct support of corporate strategy, and ultimately increased value, from the communications function. Operational elements of maturity include levels of analysis, time, budget, tools, skills, process, integration, motivations, relationships and standards.

Originality/value
In exploring the factors necessary for “mature” E&M programs, and specifically emphasizing the need for a holistic approach, along with sufficient investment and alignment, and conducive cultural factors, the research builds upon existing work examining how communication can serve to inform corporate strategy and create value for an organization. Greater understanding and application of the maturity concept has the potential to advance the field by increasing both accountability and credibility for the work done by the communications function.
“Cyclical assets” and cyclical capitalization
Authors: d'Amato Maurizio , Siniak Nikolaj , Mastrodonato Giulia 
Published: August 2019

PurposeThe purpose of this study is providing a possible methodological solution to the valuation of cyclical.assets. International Valuation Standards introduce a brand new definition of property: the cyclical asset (International Valuation Standards Council 2017, IVS 105, p. 39 and p. 41). Among different property valuation methods, normally this kind of properties is appraised using income approach. In this group of methodology, the opinion of value is based on a proportional relationship between property value and rent. In the past years, a group of methods called cyclical capitalization has been proposed (d’Amato, 2003; d’Amato, 2013;d’Amato, 2015; d’Amato, 2017a; d’Amato 2017 b; d’Amato, 2017c). This method proposes an integration between property valuation and property market cycle.Design/methodology/approachCyclical capitalization method is applied using a time series of property market rent of offices in prime location in the South Bank area in London. It consists of the determination of more than one all-risk yield to reproduce the property market cycle.FindingsA comparison between the cyclical capitalization and two traditional capitalization rate shows how the proposed model is able to provide a stable opinion of value.Research limitations/implicationsThe method may represent a contribution for the determination of the value of cyclical assets or for the mortgage lending value.Practical implicationsThis paper provides the possibility to have a property valuation method less sensitive to upturn and downturn of the property market.Social implicationsThe valuation based on cyclical capitalization are less sensitive to the upturn and the downturn of the market.Originality/valueIt is one of the first scientific paper addressing the problem of the determination of the value of cyclical assets.

Authors: Adewunmi Yewande Adetoro , Alister Anthony , Phooko Bopape , Nokukhanya Thabethe 
Published: August 2019

Purpose
The purpose of this study is to examine at energy efficiency practices within the facilities management sector and barriers to adopting energy efficient strategies, it further explored the factors that promote the employment of energy efficient practices.

Design/methodology/approach
The data were gathered by means of an electronic survey, administered to facilities managers in Johannesburg.

Findings
Energy efficient lighting is the most used energy efficiency practice. It further uncovered that occupant engagement and education is considered least, amongst current energy efficiency practices. This study revealed that the biggest barrier to the implementation of energy efficient facilities management practices was the cost implications of adopting FM strategies and rated the lowest were policies and regulations of energy efficiency standards. Cost reduction was the highest rated factor that promotes energy efficiency practices.

Practical implications
Occupants should be educated on energy efficiency through a change of their behaviours and also exposed to the benefits of using energy conservation measures. Management buy-in should be the goal of the facilities manager for the success of energy efficient practices.

Originality/value
This study is an encompassing study on energy efficiency where many aspects of energy efficiency and factors that promote energy efficiency were explored.
A study of Indonesian community’s behaviour in paying zakat
Authors: Cokrohadisumarto Widiyanto bin Mislan , Zaenudin Zaenudin , Santoso Bejo , Sumiati Siti 
Published: August 2019

Purpose
The purpose of this study is to develop a model of the Muslim community’s behaviour in paying zakat to contribute ideas on how to increase zakat recipients nationally, so as to improve the welfare of the wider community.

Design/methodology/approach
This study uses a quantitative (i.e. multiple regression analysis that involves moderating variables) and descriptive approach. Multiple regression analysis with the stepwise method is implemented to get the best regression model of community’s behaviour in paying zakat. This study takes a sample of Muslim communities in several regions (northern coast) of Central Java, Indonesia.

Findings
In the situation of the absence of government regulations relating to the obligation to pay zakat for Muslim communities, the community’s behaviour in paying zakat can be formed through two things, which are: increasing the zakat understanding and strengthening the credibility of zakat management institutions. Providing complete information to the community regarding the existence and what has been done and what will be done by the zakat management institution is very necessary.

Research limitations/implications
This study has not specifically discussed the various types of zakat paid, such as commercial zakat, agricultural zakat and professional zakat. Therefore, future research can be done more specifically to determine the behaviour of paying zakat based on the type of zakat as stated.

Practical implications
Increasing the target of collecting zakat funds from the community nationally needs: (i) educating the community about zakat more broadly and sustainably; (ii) strengthening the credibility of the zakat management institution; and (iii) strengthening the flow of information from the zakat management institution to the community.

Originality/value
Research on community’s behaviour in paying zakat has never been done before. This study analyses the behaviour of paying zakat comprehensively, namely, in terms of adherence to God and the government, awareness without coercion and the behaviour of choosing a place to pay zakat.

Published: August 2019

PurposeIslamic marketing ethics focus on the principles of equity, justice and value maximization for the welfare of society. These ethics play a vital role in elevating the standards of customer behavior. The strategy of focusing customer is now considered as important element because of rapidly changing marketing trends in Islamic banks. Therefore, the purpose of this study is to find out the important features of Islamic marketing ethics and identify their effect on customer’s satisfaction in Islamic banking.Design/methodology/approachThis study is descriptive and quantitative. Data were collected from 1000 customers of Islamic banks by applying convenient sampling technique. Smart PLS was used to check the scale validation by confirmatory factor analysis. To test the hypotheses, structural equation modeling technique was used.FindingsResults enlightened that Islamic marketing ethics play a significant role in enhancing the customer’s satisfaction. Islamic banks should focus on marketing mix along with Islamic and ethical perspectives to improve the customer’s satisfaction level.Practical implicationsThis study highlighted that Islamic marketing ethics have great impact on customer satisfaction. Therefore, Islamic banks need to concentrate on the ethical perspective of Islamic marketing in order to develop long term customer relationships. Islamic banks need to revise their marketing practices, and they should align their marketing tactics with ethical Islamic boundaries. They need to design, communicate and enforce the code of Islamic ethics within organizations.Originality/valueThis paper fulfills an identified need to study how Islamic marketing ethics effect customer satisfaction.
Individual and managerial predictors of the different forms of employee voice
Authors: Unler Ela , Caliskan Sibel 
Published: August 2019

PurposeAnalysis of employee voice has focused on the reasons and managerial issues regarding the available environment to speak up. The purpose of this paper is to understand the effect of management attitude on employee voice with the mediating effect of individual’s perceived psychological safety (PPS). Besides, the role of job satisfaction (JS) and being individualist/collectivist as moderators over the effect of psychological safety on employee voice are analyzed.Design/methodology/approachThe authors constructed a framework based on Maynes and Podsakoff’s (2014) view that identifies four different types of voice behavior (supportive, constructive, defensive and destructive). In total, 286 questionnaires were collected from employees working in telecommunication industry.FindingsBased on analysis, positive management attitude facilitates supportive and constructive voice (CV) and reduces destructive voice (DESV). PPS mediates the relationship with management attitude and DESV. JS level facilitates supportive CV and reduces DESV. Collectivism level of employees moderates PPS and DESV. Path analysis results showed a similar model for mediation effect of safety, and showed a better model fit and explanation for trust mediation between LMX and supportive, constructive and DESV. Supported assumptions would be discussed-based social exchange theory and signaling theory.Research limitations/implicationsThe sample is relatively small which limits the external validity of the findings.Practical implicationsResults revealed the managerial attitude over employee voice through perceived work environment (psychological safety) and trust.Originality/valueThis study is one of the first that integrates not only constructive but also DESV into the model.

Authors: Cuan-Urquizo Enrique , Martínez-Magallanes Mario , Crespo-Sánchez Saúl E. , Gómez-Espinosa Alfonso , Olvera-Silva Oscar , Roman-Flores Armando 
Published: August 2019

Purpose
The purpose of this paper is to study the feasibility of the fabrication of circle arc curved-layered structures via conventional fused deposition modeling (FDM) with three-axis machines and to identify the main structural parameters that have an influence on their mechanical properties.

Design/methodology/approach
Customized G-codes were generated via a script developed in MATLAB. The G-codes contain nozzle trajectories with displacements in the three axes simultaneously. Using these, the samples were fabricated with different porosities, and their influence on the mechanical responses evaluated via tensile testing. The load-displacement curves were analyzed to understand the structure-property relationship.

Findings
Circled arc curved-layered structures were successfully fabricated with conventional three-axis FDM machines. The response of these curved lattice structures under tensile loads was mapped to three main stages and deformation mechanisms, namely, straightening, stretching and fracture. The micro-structure formed by the transverse filaments affect the first stage significantly and the other two minimally. The main parameters that affect the structural response were found to be the transverse filaments, as these could behave as hinges, allowing the slide/rotation of adjacent layers and making the structure more shear sensitive.

Research limitations/implications
This paper was restricted to arc-curved samples fabricated with conventional three-axis FDM machines.

Originality/value
The FDM fabrication of curved-structures with controlled porosity and their relation to the resulting mechanical properties is presented here for the first time. The study of curved-lattice structures is of great relevance in various areas, such as biomedical, architecture and aerospace.
Assessing Tax Risk: Practitioner Perspectives
Authors: Neuman Stevanie S. , Omer Thomas C. , Schmidt Andrew P. 
Published: August 2019

ABSTRACTThis study uses insights from tax practitioners and tax authorities to define and develop an estimate of ex ante tax risk that is independent of common tax outcomes studied in prior literature. Validation tests confirm that our tax risk measure (i) represents the predictable and unpredictable uncertainty inherent in the three sources of tax risk (i.e., economic risk, tax law uncertainty, and inaccurate information processing) and (ii) is a construct different from tax avoidance, tax uncertainty, and general business risk. Using our tax risk measure, we address two research questions of interest to academics and practitioners. First, we examine the association between tax risk and long‐run tax avoidance and find a negative association between tax risk and future long‐run cash effective tax rates (ETRs). Second, we consider the extent to which unrecognized tax benefits (UTBs) reflect tax risk, tax avoidance, or financial reporting incentives and demonstrate that our tax risk measure explains a substantial portion of UTBs, incremental and relative to measures of information risk, conditional conservatism, unconditional conservatism, and tax avoidance. Our study offers a measure of tax risk that, consistent with the Scholes‐Wolfson paradigm, reflects the tax risk inherent in all business activities, not just tax avoidance activities; has unique industry effects; and contributes to our understanding of the factors that affect tax planning decisions and result in variation in firms' ETRs. Our findings will help managers and tax practitioners focus on industry‐specific tax risk components, assess risk during tax planning initiatives, exercise caution when engaging in additional risk if ETRs are low, and adapt tax risk strategies to fit specific company needs. We enhance future tax research by improving the definition and measurement of tax risk.
