Impact of social sustainability orientation and supply chain practices on operational performance
Authors: Croom Simon , Vidal Natalia , Spetic Wellington , Marshall Donna , McCarthy Lucy 
Published: August 2018

PurposeSocially sustainable supply chain (SSSC) practices address pressing social issues and may provide operational benefits as well as positive impacts on society. However, due to gaps in the current knowledge, it is difficult to know what practices will provide benefits and what management orientations can maximize the impact of these practices on operational performance. The purpose of this paper is to advance the knowledge on the effect of social sustainability orientation on operational performance by examining the mediating roles of basic and advanced SSSC practices and the moderating role of long-term orientation (LTO).Design/methodology/approachData were collected through a survey of US-based companies about their relationships with key suppliers. Confirmatory factor analysis and multiple regression were used to test the proposed moderated mediation model.FindingsSurprisingly, sustainability orientation predicts operational performance through advanced but not basic SSSC practices. Results also indicate that the effect of sustainability orientation on operational performance is significantly moderated by LTO.Research limitations/implicationsResults are limited by the US context, the cross-sectional nature of the research, the use of a single-respondent survey instrument and the challenges of measuring LTO.Practical implicationsManagers and policymakers should be aware of the limitations of adopting basic SSSC practices on the performance of their operations. Advanced practices provide a more robust business case and significantly and positively impact operational performance. In addition, the interaction of a sustainability orientation and LTO can lead to even greater improvements in firms’ operational performance. Firms with the highest levels of social sustainability and LTOs attain superior operational performance.Originality/valueThis study contributes to the growing literature on sustainable supply chain management (SSCM) and extends this literature by focusing on social sustainability practices, identifying specific practices that impact and the orientations that maximize operational performance. The authors contribute to the growing literature on the importance of manager’s temporal orientation and provide nuance to emerging SSCM theory by exposing the interplay of these orientations and the impact of SSSC practice adoption.
SmartMedicist: a context-aware system for recommending an alternative medicine
Authors: Swain Sujata , Niyogi Rajdeep 
Published: August 2018

PurposeThis study aims to discuss a context-aware system, SmartMedicist, which can recommend an alternative medicine from a set of available medicines present at a patient’s home for an unavailable medicine. The system is applied to the chronic disease patients only. The system requires only a smartphone, and provides a reminder to the patient to take medicine at appropriate times and to procure medicines from drug store. The system discusses the output method for the physically challenged patient. Although there are existing systems that can remind a patient for taking medicines, the authors are not aware of any such system that has the capability to recommend an alternative medicine for the prescribed medicine.Design/methodology/approachThe study developed a pharmacology knowledge base that consists of a representation of a set of diseases, according to family, type and medicines, in a k-ary tree. An alternative medicine is recommended based on the set of available medicines and knowledge base.FindingsWe considered four diseases: Hypertension, Gastritis, Alzheimer’s disease, and Parkinson; and performed several experiments for each disease for the different number of available medicines. The execution time to find an alternative medicine (if any) in each case is around four seconds.Originality/valueThe proposed system is cost effective and affordable for most families in India. Although the proposed system is not a substitute of a doctor, this system will enhance the safety golden period for a patient to consult a doctor in the emergency exhaustion of the prescribed medicines.
Green supply chain management and the circular economy
Authors: Liu Junjun , Feng Yunting , Zhu Qinghua , Sarkis Joseph 
Published: August 2018

Purpose
Green supply chain management (GSCM) and the circular economy (CE) overlap but also differ. The purpose of this paper is to clarify linkages between these two concepts. It identifies mutual theory applications used to study GSCM and CE.

Design/methodology/approach
A systematic literature review is conducted to identify theories from GSCM and CE studies. A critical analysis explores the theories that can provide mutual applications between GSCM and CE fields. Propositions are developed.

Findings
In all, 12 theories are applied in both GSCM and CE studies. Several theories are only applied in GSCM studies, but can help to advance CE study. These theories include complexity, transaction cost economics, agency, and information theories. Each of the eight theories only applied to CE can potentially advance GSCM study.

Research limitations/implications
The findings contribute to further theory development for both GSCM and CE study. A methodological review can advance theoretical development and cross-pollination in both fields.

Originality/value
This work is the first study to explicitly explore linkages of GSCM and CE from a theoretical perspective.
Customers’ valuation of time and convenience in e-fulfillment
Authors: Gawor Tobias , Hoberg Kai 
Published: August 2018

PurposeThe purpose of this paper is to derive monetary benchmarks and managerial implications for omni-channel retailers’ B2C e-fulfillment strategies by investigating the trade-offs between lead time, delivery convenience and total price including shipment in the context of online electronics retailing.Design/methodology/approachBased on a choice-based conjoint analysis among 550 US online shoppers, the monetary values of lead time and convenience were calculated in a log-log regression model. In addition, latent class segmentation was applied to identify consumer segments according to their differing e-fulfillment preferences.FindingsFrom a consumer perspective, the analysis suggests that price is the most important criteria in omni-channel retailer selection, followed by lead time and convenience. The value of time is, on average, $3.61 per day. Regarding convenience, the results indicate that delivery to the home is highly preferred over pick-up options. The value of the consumer’s travel time was estimated at $10.62 per hour. The latent class segmentation identified four segment groups with different preferences.Research limitations/implicationsTo validate the findings, future research could analyze real data from omni-channel retailers’ customers’ buying behavior. It should also be interesting to extend the research to other price ranges, market segments and e-fulfillment factors, such as return options, shop ratings and membership programs aiming for further generalization.Practical implicationsThe findings guide omni-channel retailers to focus on efficient B2C e-fulfillment strategies. Considerable competitive advantages may be gained by reducing lead times and offering convenient delivery in line with the lead time valuation of the identified customer segment.Originality/valueThis study fills gaps in the academic research of consumer behavior in retailer selection, which has primarily concentrated on the choice between “brick-and-mortar” and online sales channels. It paves the way for a more service-oriented perspective in omni-channel retailing research.
A stable cellular automaton model for composite materials with defects
Authors: Wu Jun , Huang Zhangcan 
Published: August 2018

Purpose
As the internal defects (pore defect) of materials formed during the preparation of the composite material have important effects on wear process, the model has been improved to simulate it.

Design/methodology/approach
Materials with defects were simulated by an improved cellular automaton model which show changes in three-dimensional topography, temperature of surface and coefficient of friction (COF) during wear process.

Findings
It is found that defects increase temperature of material surface. Besides, the materials with little defects have a smaller COF than base materials, as the large block defects make the COF larger than base materials.

Originality/value
Except for effects of defects were simulated in model, how to initialize the surface temperature status that many reports do not take into account can be preferred. And the model is convenient to simulate complex composite materials by setting different properties of cells.

Authors: Tsai Feng Che , Lee Yann Long , Yeh Ju Chun 
Published: August 2018

Purpose
This paper aims to develop an electrochemical abrasive jet machining (ECAJM) technology to investigate the surface machining effect of Ti-6Al-4V alloy.

Design/methodology/approach
First, the ECAJM equipment was set up, and a series of experiments for the surface machining of Ti-6Al-4V alloy was performed.

Findings
The experimental results show that the flowing abrasives of 0.05 Wt.% can effectively remove the TiO2 oxide film of Ti-6Al-4V alloy surface. In addition, the flowing abrasives produce cutting machining effect on the surface of titanium aluminum alloy, and the oxide film can be removed effectively. For the case of machining pressure of 0.4 Mpa and machining gap of 0.4 mm, the processing efficiency can be achieved up to 20 µm/s.

Originality/value
Under different machining pressure, the flowing abrasive with high kinetic energy impacting the Ti-6Al-4V alloy surface and the oxide film produced from the electrolytic reaction process can be removed effectively, thereby enhancing the efficiency of electrochemical machining process.
Effect of surface texture on the friction of WC-TiC/Co cemented carbide under a water-miscible cutting fluid environment
Authors: Pang Minghua , Liu Xiaojun , Liu Kun 
Published: August 2018

Purpose
This study aims to clarify the influence mechanism of surface texture (arrays of circular/square and concave/convex) on the frictional properties of WC-TiC/Co cemented carbide under a water-miscible cutting fluid (JAEGER SW-105, 5 per cent) environment.

Design/methodology/approach
Four types of textured cemented carbide surfaces (arrays of circular/square and concave/convex that have different textured densities and sizes) were fabricated using laser surface technology. Pin-on-disc tests between an AISI 304 stainless steel ball and WC-TiC/Co cemented carbide samples were carried out for a variety of normal loads (1, 3 and 5 N) under a water-miscible cutting fluid environment. The effects of textured type, density and size on the friction coefficient were obtained.

Findings
Compared to a smooth surface, some textured samples successfully resulted in a reduced friction coefficient. The friction coefficient of textured WC-TiC/Co cemented carbide samples depended greatly on the textured type, density and size. Given the increase in textured density (ranging from 10 to 30 per cent), the friction coefficient of the test samples first decreased and then increased for all normal loads (1, 3 and 5 N), and the minimum friction coefficient was obtained at the textured density of 20 per cent. The concave textured surface showed obvious advantages in friction coefficient reduction regardless of textured density, size and normal load compared with the convex textured surface. Finally, the correlation between textured diameter/length and Hertzian contact width was studied for various normal loads and texture sizes. A 2.6 ratio of textured diameter/length to Hertzian contact width is recommended under for lubricated sliding contact with the water-miscible cutting fluid.

Originality/value
The main contribution of this work is in providing a design reference and obtaining an essential understanding on the effect of surface texture (arrays of circular/square and concave/convex) on the friction of WC-TiC/Co cemented carbide under a water-miscible cutting fluid environment.
Surface texture processing for tribological performance improvement of UHMWPE-based water-lubricated bearings
Authors: Wu Zumin , Sheng Chenxing , Guo Zhiwei , Li Yifei , Malekian Reza , Li Zhixiong 
Published: August 2018

Purpose
Water-lubricated bearings can significantly reduce the pollution to environment because the traditional oil lubricant is replaced by water in the bearings. The ultrahigh molecular weight polyethylene (UHMWPE) has proven to be effective and reliable for the manufacturing of water-lubricated bearings. However, limited work has been done to address the improvement of the tribological performance of the UHMWPE-based water-lubricated bearings using surface texture processing. This paper aims to investigate the effects of bar-grooved surface on the tribological performance improvement of UHMWPE-based water-lubricated bearings.

Design/methodology/approach
For the first time, the bar grooves were processed on the surfaces of UHMWPE-based water-lubricated bearings. The CBZ-1 friction and wear tester have been used to test the wear and friction performance of the bearing samples. The LI laser interference surface contour graph and the digital microscope have been used to measure the surface morphology of the specimens. The tribological characteristics of the tested bearings were analyzed.

Findings
With bar grooves added on the surfaces of the specimens, the friction coefficient of the specimens were lower than that of the specimens without surface texture processing; the wear quantity of the two kinds of specimens were almost the same; by using the LI laser interference surface contour graph and the digital microscope to measure the surface morphology of the specimens, the furrows of the specimens with bar grooves were narrower and shallower than that of the specimens without bar grooves.

Practical implications
The paper implicates that the surface texture processing using bar grooves can reduce the friction coefficient and prolong the service life of the water-lubricated bearings in practical applications.

Originality/value
This paper fulfills an identified need to provide important theoretical and experimental support to the design of water-lubricated bearings in practical applications.
Assessing the quality of information technology infrastructure services
Authors: Freitas André Luís Policani , Monteiro Gustavo Antonio Pessanha , Costa Helder Gomes 
Published: August 2018

Purpose
Despite existing advances in information technology infrastructure services (ITISs), there remains no consensus in the literature regarding what dimensions or criteria are best suited for the measurement of their quality. The purpose of this paper is to fill this gap, proposing a methodological approach to measuring the quality of ITISs, as perceived by users.

Design/methodology/approach
Cronbach’s α and item-total correlations were used to measure the reliability of the questionnaire; multiple linear regression analysis was employed to determine the items (criteria) most related to the quality of ITISs; and finally, importance–performance analysis was conducted to determine the most critical criteria in service provision. An exploratory study was conducted to evaluate the quality of ITISs at a Brazilian university.

Findings
Control of the activities of the information technology (IT) team, periodic maintenance of hardware and software, the security policy and the skill of the labor affect the quality of services most, relative to the dimensions of infrastructure, people and processes.

Practical implications
The results indicate what dimensions and items should be considered by IT managers to improve the quality of ITISs. Special attention should be paid to the effective use of equipment, software and network infrastructure: it should be ensured that these are in good working order and can be utilized by users who expect to be trained to take advantage of their functions.

Originality/value
This paper shows how to integrate relevant techniques to assess the quality of ITISs. An original set of criteria to evaluate the quality of ITISs, derived from a systematic review of the literature, is suggested.
Determinants of visual analytics adoption in organizations
Authors: Daradkeh Mohammad Kamel 
Published: August 2018

PurposeVisual analytics is increasingly becoming a prominent technology for organizations seeking to gain knowledge and actionable insights from heterogeneous and big data to support decision-making. Whilst a broad range of visual analytics platforms exists, limited research has been conducted to explore the specific factors that influence their adoption in organizations. The purpose of this paper is to develop a framework for visual analytics adoption that synthesizes the factors related to the specific nature and characteristics of visual analytics technology.Design/methodology/approachThis study applies a directed content analysis approach to online evaluation reviews of visual analytics platforms to identify the salient determinants of visual analytics adoption in organizations from the standpoint of practitioners. The online reviews were gathered from Gartner.com, and included a sample of 1,320 reviews for six widely adopted visual analytics platforms.FindingsBased on the content analysis of online reviews, 34 factors emerged as key predictors of visual analytics adoption in organizations. These factors were synthesized into a conceptual framework of visual analytics adoption based on the diffusion of innovations theory and technology–organization–environment framework. The findings of this study demonstrated that the decision to adopt visual analytics technologies is not merely based on the technological factors. Various organizational and environmental factors have also significant influences on visual analytics adoption in organizations.Research limitations/implicationsThis study extends the previous work on technology adoption by developing an adoption framework that is aligned with the specific nature and characteristics of visual analytics technology and the factors involved to increase the utilization and business value of visual analytics in organizations.Practical implicationsThis study highlights several factors that organizations should consider to facilitate the broad adoption of visual analytics technologies among IT and business professionals.Originality/valueThis study is among the first to use the online evaluation reviews to systematically explore the main factors involved in the acceptance and adoption of visual analytics technologies in organizations. Thus, it has potential to provide theoretical foundations for further research in this important and emerging field. The development of an integrative model synthesizing the salient determinants of visual analytics adoption in enterprises should ultimately allow both information systems researchers and practitioners to better understand how and why users form perceptions to accept and engage in the adoption of visual analytics tools and applications.

Authors: Kumar Rahul , Singh Jeeoot 
Published: August 2018

Purpose
The purpose of this paper is to assess different five variables shear deformation plate theories for the buckling analysis of FGM plates.

Design/methodology/approach
Governing differential equations (GDEs) of the theories are derived by employing the Hamilton Principle. A polynomial radial basis function (RBF)-based Meshless method is used to discretize the GDEs, and a MATLAB code is developed to solve these discretize equations.

Findings
Numerical results are obtained for buckling loads. The results are compared with other available results for validation purpose. The effect of the span-to-thickness ratio and grading index is observed. It is observed that some theories underpredict the deflection for thick plates, while at the same time they seem to be in good agreement with other theories for thin plates.

Originality/value
This paper assesses the different theories with the same method to determine their applicability.
