Authors: Rashidi Iman , Kolsi Lioua , Ahmadi Goodarz , Mahian Omid , Wongwises Somchai , Abu-Nada E. 
Published: August 2019

Purpose
This study aims to investigate a three-dimensional computational modelling of free convection of Al2O3 water-based nanofluid in a cylindrical cavity under heterogeneous heat fluxes that can be used as a thermal storage tank.

Design/methodology/approach
Effects of different heat flux boundary conditions on heat transfer and entropy generation were examined and the optimal configuration was identified. The simulation results for nanoparticle (NP) volume fractions up to 4 per cent, and Rayleigh numbers of 104, 105 and 106 were presented.

Findings
The results showed that for low Ra (104) the heat transfer and entropy generation patterns were symmetric, whereas with increasing the Rayleigh number these patterns became asymmetric and more complex. Therefore, despite the symmetric boundary conditions imposed on the periphery of the enclosure (uniform in Ɵ), it was necessary to simulate the problem as three-dimensional instead of two-dimensional. The simulation results showed that by selecting the optimal values of heat flux distribution and NP volume fraction for these systems the energy consumption can be reduced, and consequently, the energy efficiency can be ameliorated.

Originality/value
The results of the present study can be used for the design of energy devices such as thermal storage tanks, as both first and second laws of thermodynamics have been considered. Using the optimal design will reduce energy consumption.
The effect of the valence of sponsorship information on consumers’ attitudes toward the sponsor brand
Authors: Dick Christopher 
Published: August 2019

Purpose
To date, research on sponsorship considers the effects of only positive or only negative sponsorship information on consumers’ attitudes toward the sponsor brand. However, in practice, sometimes mixed information (positive and negative) is available that influences consumers’ sponsor evaluations. To mirror the information situation of the real world, the purpose of this paper is to investigate how the valence of sponsorship information (only positive vs mixed vs only negative) and the strength of sponsorship information (weak vs strong) influence the consumers’ attitudes toward the sponsor brand.

Design/methodology/approach
This research uses an experimental research design (n=210). Data were collected among students of a German university.

Findings
The results reveal that when the strength of information was weak, attitudes in the mixed information condition were not significantly worse than in the only positive condition and significantly better than in the only negative condition. In addition, when the strength of information was strong, attitudes in the mixed information condition were significantly worse than in the only positive condition and significantly better than in the only negative condition.

Practical implications
This study offers several practical recommendations regarding the sponsors’ evaluation of their investments and the decision to maintain or exit the sponsorship of a controversial object.

Originality/value
This study expands the research on the effects of available sponsorship information on consumers’ sponsor evaluation. The present research highlights the effects of different types of sponsorship information on consumers’ attitudes and considers the strength of information as a boundary condition of these effects.

Published: August 2019

PurposeThe purpose of this paper is to assess the resilience of tourism businesses in a coastal city in the USA to coastal hazards and severe weather events. The researchers developed a framework for assessing the resilience of coastal tourism businesses and demonstrated the applicability of the framework using the case study of Virginia Beach.Design/methodology/approachResearchers conducted structured, face-to-face interviews with tourism business owners and managers, using an instrument based on an assessment framework with five components: vulnerability, business planning and operations, preparation and recovery planning, communications and workforce. In total, 32 participants representing 42 businesses in the accommodations, restaurants, retail and activities sectors at the Virginia Beach Oceanfront were interviewed.FindingsMany participants did not feel highly vulnerable due to structural mitigation efforts taken by the city. Larger businesses undertook more strategic planning, preparedness and recovery planning. All businesses had effective ways of communicating with staff and customers, and through membership in local organizations, had access to resources. While not all businesses prioritized training for employees, they recognized the importance of providing support for staff during severe weather events.Originality/valueAs one of the few studies on tourism resilience in the USA, this study highlights the variability of resilience among tourism businesses within a destination.
Entrepreneurial marketing: an analytical viewpoint on perceived quality and customer delight
Authors: Dubey Prince , Bajpai Naval , Guha Sanjay , Kulshreshtha Kushagra 
Published: August 2019

Purpose
Entrepreneurial marketing is a hybrid concept of entrepreneurship and marketing defining business for future challenges. This study aims to examine the following two issues of entrepreneurial marketing concerning impact of perceived quality on customer delight: first, identifying entrepreneurial marketing factors of delight and customer perceived quality to develop the model; second, applying the aforesaid model to discriminate customer delight in categories of gender as male delight and female delight.

Design/methodology/approach
In this endeavour, the authors examined the data collected from survey of Indian mobile users. In total ten perceived quality predictor variables are used to measure customer delight. Further, for identifying the difference in male delight and female delight, discriminant analysis is used.

Findings
The conceptual and empirical vantage point of study provides a framework to entrepreneurs emphasizing on male and female customers distinctly during marketing.

Research limitations/implications
The results are used to sketch the profile of male and female customer segment, and innovative applications are discussed for business success. Though proposed approach is limited to gender, mobile users still open the avenue for researchers to work on other demographic factors and product categories.

Practical implications
The theoretical underpinnings warrant practical applications of quality dimensions in telecom market for creation of customer delight. The present gender classification of customer delight will assist the entrepreneurs, intrapreneurs and product developers in developing the competitive business policy.

Social implications
The classification of male and female delight suggests the female segment of Indian telecom market is socially important and as similar to the male segment.

Originality/value
The study is a novel assessment of customer delight on gender quality perception contributing the newly explored concept of entrepreneurial marketing.

Leader–member exchange and employee health: an exploration of explanatory mechanisms
Authors: Gregory Brian , Osmonbekov Talai 
Published: August 2019

PurposeThe impact of employee health on organizations, individual employees and society as a whole is vast. The purpose of this paper is to explore the relationship between leadership–member exchange (LMX) and employee mental and physical health. Additionally, two variables with strong empirical and theoretical ties to employee health (empowerment and stress) are explored as potential mediators.Design/methodology/approachSurvey responses from 182 employees across two organizations were collected to measure study variables. Structural equation modeling techniques were used to analyze data and test hypotheses.FindingsAn association between LMX and employee health was found to be fully mediated by both empowerment and stress.Originality/valueThese findings contribute to the literature by providing evidence of the association between leadership and both the mental and physical health of employees. This phenomenon highlights the significant impact that leaders have on subordinates both at work and in their general lives outside of the workplace. Understanding the mediating pathways through which leadership comes to impact employee health creates new knowledge regarding the manner in which constructs as disparate as leadership and employee health come to form an association.
Process porosity and mechanical performance of fused filament fabricated 316L stainless steel
Authors: Damon James , Dietrich Stefan , Gorantla Sasidhar , Popp Uwe , Okolo Brando , Schulze Volker 
Published: August 2019

Purpose
This study aims to investigate the correlation between build orientation characteristics, part porosity and mechanical properties of the fused filament fabrication (FFF) process to provide insight into pore formation mechanisms and to establish guidelines for optimal process configurations.

Design/methodology/approach
Micro computed tomography and metallographic sections provide the basis for a correlation between porosity and extrusion path. Using the correlations found in this study, the way to improve printing strategies and filament properties can be deduced directly from an analysis of the print path and the final influence on mechanical performance.

Findings
With metal-FFF 3D printing technology, near-dense parts (0.5 Vol.%) can be fabricated. The pore architecture is strongly connected to the build direction and print strategy with parallel, elongated pore channels. Mechanical values of FFF samples are similar to metal injection-molded (MIM) parts, except the elongation to fracture. The high difference of yield strength of sintered samples compared to laser powder bed fusion (LPBF) samples can be attributed to the finer grains and a Hall–Petch hardening effect. The conclusions derived from this study are that the presented process is capable of producing comparable part qualities compared to MIM samples, with higher build rates in comparison to LPBF processes.

Originality/value
316L stainless steel was successfully manufactured via FFF. This paper also addresses the effects of scanning strategies on the resulting porosity and proposes improvements to reduce residual porosity, thus increasing the mechanical performance in the future.
Working toward a culture of instructional assessment
Authors: Smith Meghan Wanucha 
Published: August 2019

Purpose
This paper describes the development of a culture of assessment in an academic library’s information literacy program offered through its Research and Instructional Services department.

Design/methodology/approach
Incorporating components from change management, adult learning and organizational authority approaches offers opportunities for those without managerial duties to encourage others to incorporate student learning assessment into their work. Over a three-year period, instruction assessment was refreshed and renewed in an information literacy program and individual sessions through workshops, new assessment techniques and reflective activities.

Findings
Approaching cultural change through small, incremental activities can be a useful method for encouraging buy-in and engagement from library workers. Efforts at one academic library resulted in increased rates of assessment in instruction sessions and self-reported willingness to use assessment techniques in the future.

Research limitations/implications
This paper is limited to the analysis and building of an assessment culture within a single academic library department.

Originality/value
Changing organizational culture is a complex undertaking, particularly for those without supervisory duties. This paper applies approaches of change leadership and assessment from existing literature to an instruction program through the lens of “coordinator syndrome.” Librarians from institutions where assessment is dispersed throughout an organization or where assessment has been seen in a negative light may find a similar incremental approach useful in their own context.

Authors: Warnecke Danielle , Wittstock Rikka , Teuteberg Frank 
Published: August 2019

Purpose
Benchmarks provide a strategic tool for assessing the sustainability impacts of urban development. Addressing the need for practitioners to evaluate their initiatives, track progress and determine their competitive position, this paper aims to introduce the conception and implementation of a smart city maturity assessment and benchmarking tool.

Design/methodology/approach
Following a design science approach, application objectives are defined based on a review of literature and related benchmarking tools. Focusing on a subset of functions for the prototype version, these objectives are operationalized by development of a smart mobility maturity model, indicator set and survey. A two-step evaluation by means of a test run using data of five cities and expert interviews confirms the tool’s functionality.

Findings
Compliance with the defined objectives is achieved by implementation of a Web-based self-assessment tool using objective indicators. Future development iterations are to integrate additional smart city action fields.

Practical implications
Delivering a city’s maturity level, the tool enables stakeholders to measure the impact of their initiatives. Benchmarking functions for tracking progress and comparison with other projects are provided in the form of graphical analyses. Ac-tionable guidance is supplied for improving the city’s standing.

Social implications
Strategies supporting a sustainable lifestyle are crucial for smart city development, as the shaping of attractive living spaces and a reliable information and communication technology and physical infrastructure form major selling points for attracting skilled workers, businesses, tourists and citizens.

Originality/value
Enabling practitioners to self-evaluate their initiatives, providing the option to track progress and supplying guidance for improving a city’ standing, the proposed solution represents a novel form of knowledge transfer.
The cryptic regulation of diversity by functionally complementary large tropical forest herbivores

Published: August 2019

Abstract

Tropical forests hold some of the world's most diverse communities of plants. Many populations of large‐bodied herbivores are threatened in these systems, yet their ecological functions and contribution towards the maintenance of high levels of plant diversity are poorly known. The impact of these herbivores on plant communities through antagonistic seed and seedling predation has received much attention, whilst their relevance as seed dispersal agents has been largely overlooked in experimental studies.

Here, we tested how two key and functionally distinct large generalist mammalian herbivore species (the tapir Tapirus terrestris – a solitary browser and generalist seed disperser, and the white‐lipped peccary Tayassu pecari – a group‐living generalist seed/seedling predator) affect spatiotemporal patterns of diversity of seedling communities in tropical forests. We conducted a long‐term multi‐region landscape‐scale exclusion experiment across four regions of the Atlantic forest of Brazil, representing a functional gradient of defaunation where these species were either present and absent in isolation and in combination.

Our results indicate that mammalian herbivores have a substantial role in regulating beta diversity in space and time. Seedling recruitment was strongly limited by the presence of the seed/seedling predator species (the peccary), but the presence of the browser and seed disperser (the tapir) had null net effects. Alpha diversity of seedlings at the community level did not respond to large herbivore exclusion at any region, whereas beta diversity decreased only where both herbivores were simultaneously excluded. Surprisingly, the synergic positive effect of both herbivore types on beta diversity was linked to increased evenness amongst dominant plant species, and a simultaneous decrease in alpha diversity of rare species.

Synthesis. Together, these results challenge the common perception that large tropical forest herbivores maintain tropical forest diversity through antagonistic interactions, suggesting instead a synergistic effect of antagonistic predation and mutualistic seed dispersal on regional compositional diversity and local community assembly. We suggest that the defaunation of large‐bodied herbivores with complementary functions strongly affects the structure and dynamics of plant communities through cryptic mechanisms that remain largely unexplored.
Can Vision 2020 be Far Away? Malaysia's Transformation Problems to a High‐income Economy
Authors: Fleming Daniel , Søborg Henrik 
Published: August 2019

AbstractAt the beginning of 1990s, the then Prime Minister Mahathir Mohamad set the goal that Malaysia in 2020 should become a high‐income economy and a vigorous and economically just middle class society. We are not far away from 2020. We therefore raise the question whether Malaysia is close to or far away of becoming a high‐income economy with this economic trap issue in the article. Instead, we focus on income inequality as an inroad to economy seen from an OECD country level perspective. In our examination of this question, we first discus different strands in the debate on transformation from middle‐income to high‐income economies. The debate has focused on the middle‐income trap issue especially from an economic perspective. It is an interesting and fruitful input to the transformation debate, particularly the question whether lack of industrial upgrading and deepening keeps middle‐income economies back from becoming high‐income economies. We do not deal so much with Malaysia's transformation problems. From our point of view, income inequality (high Gini coefficient) is an important but often neglected element in the mosaic to explain Malaysia's transformation problems both in a domestic and global policy perspective. We examine income inequality and transformation to a high‐income economy from different angles. We look into the business structure; income distribution compared with high‐income economies; household income distribution, consumption, lifestyle and the middle class; education and tax system as lever or barrier for reducing income inequality; old and new political coalitions as drivers for maintenance or change of income inequality. Through this analysis, we seek at the same time to highlight whether Malaysia is close to become a vigorous and economically just middle class society.

Published: August 2019

BackgroundGene mutation analysis from plasma circulating tumor DNA (ctDNA) can provide timely information regarding the mechanism of resistance that could translate to personalised treatment. We compared concordance rate of next generation sequencing (NGS) and droplet digital polymerase chain reaction (ddPCR) in the detection of the EGFR activating and T790M mutation from plasma ctDNA with diagnostic tissue biopsy‐based assays. The second objective was to test whether putative osimertinib resistance associated mutations were detectable from plasma using NGS.MethodsFrom January 2016 to December 2017, we prospectively collected plasma samples from patients prior to commencement of second‐ or third‐line osimertinib therapy and upon disease progression, in a single tertiary hospital in South Western Sydney, Australia. Amplicon‐based NGS and ddPCR assays were used to detect activating epidermal growth factor receptor (EGFR) and T790M mutations in 18 plasma samples from nine patients; all patients were required to have tissue biopsies with known EGFR status.ResultsHigh concordance of allelic fractions were seen in matched plasma NGS and ddPCR for activating EGFR mutations and T790M mutations (R2 = 0.92, P < 0.0001). Using tissue biopsies as reference standard, sensitivity was 100% for NGS and 94% for ddPCR. Several possible osimertinib resistance associated mutations, including PIK3CA, BRAF and TP53 mutations, were detected by NGS in samples upon progression on osimertinib therapy.ConclusionddPCR assays for EGFR mutations appear to be as sensitive and highly concordant as amplicon‐based NGS. NGS has the ability to detect novel resistance mutations.
