The call of ambiguity: lingering over uncertainty as classroom practice
Authors: McKenzie Cori Ann , Bender Geoff 
Published: December 2020

PurposeThis paper encourages teachers and scholars of English Language Arts to engage deliberately with literary ambiguity.Design/methodology/approachThrough close attention to ambiguous moments in commonly taught texts, the essay argues that explicit attention to ambiguity can support four enduring goals in the field: fostering social justice, developing students’ personal growth, cultivating dispositions and skills for democracy and engendering disciplinary literacy skills.FindingsThe readings suggest the following: first, wrestling with ambiguities in Harper Lee’s To Kill a Mockingbird may foster critical orientations needed in the fight for social justice; second, ambiguities in Gene Luen Yang’s American Born Chinese may support students’ personal development; third, questions generated by Walter Dean Myers’ Monster invite readers to practice skills needed for democracy; finally, exploring divergent interpretations of Laurie Halse Anderson’s Speak may develop students’ disciplinary literacy skills.Originality/valueIn an era marked by standardization and accountability, it may be difficult for teachers and scholars to linger with literary ambiguity. By underscoring the instrumental potential of literary ambiguity, the essay illustrates why and how teachers might reject this status quo and embrace the indeterminacy of literary ambiguity.
Unsteady axisymmetric flow and heat transfer of a hybrid nanofluid over a permeable stretching/shrinking disc
Authors: Khashi'ie Najiyah Safwa , Arifin Norihan M. , Pop Ioan 
Published: December 2020

Purpose
This study aims to analyze the unsteady flow of hybrid Cu-Al2O3/water nanofluid over a permeable stretching/shrinking disc. The analysis of flow stability is also purposed because of the non-uniqueness of solutions.

Design/methodology/approach
The reduced differential equations (similarity) are solved numerically using the aid of bvp4c solver (Matlab). Two types of thermophysical correlations for hybrid nanofluid (Type 1 and 2) are adopted for the comparison results. Using correlation Type 1, the heat transfer and flow analysis including the profiles (velocity and temperature) are presented in the figures and tables with different values control parameters. Three sets of hybrid nanofluid are analyzed: Set 1 (1% Al2O3 + 1% Cu), Set 2 (0.5% Al2O3 + 1% Cu) and Set 3 (1% Al2O3 + 0.5% Cu).

Findings
The comparison of numerical values between present (Types 1 and 2 correlations) and previous (Type 2 correlations) results are in a good compliance with approximate percent relative error. The appearance of two solutions is noticed when the suction parameter is considered and the unsteady parameter is less than 0 (decelerating flow) for both stretching and shrinking disc while only one solution is possible for steady flow. The hybrid nanofluid in Set 1 can delay the separation of boundary layer but the hybrid nanofluid in Set 3 has the greatest heat transfer rate. Moreover, the inclusion of wall mass suction for stretching case can generate a significant increment of heat transfer rate approximately 90% for all fluids (water, single and hybrid nanofluids).

Originality/value
The present findings are novel and can be a reference point to other researchers to further analyze the heat transfer performance and stability of the working fluids.
Heat transfer enhancement with nanofluid in an open enclosure due to discrete heaters mounted on sidewalls and a heated inner block
Authors: Getachew Ushachew Endalkachew , Sharma Mukesh Kumar , Rashidi Mohammad Mehdi 
Published: December 2020

Purpose
The purpose of this study is to explore the heat transfer enhancement in copper–water nanofluid flowing in a diagonally vented rectangular enclosure with four discrete heaters mounted centrally on the sidewalls and a square-shaped embedded heated block in the influence of a static magnetic field.

Design/methodology/approach
Four discrete heaters are mounted centrally on each sidewall of the rectangular enclosure that embraces a heated square block. A static transverse magnetic field is acting on the vertical walls. The Navier–Stokes equations of motion and the energy equation are modified by incorporating Lorentz force and basic physical properties of nanofluid. The derived momentum and energy equations are tackled numerically using the successive over-relaxation technique associating with the Gauss–Seidel iteration technique. The effects of physical parameters connected to dynamics of flow and heat convection are explored from streamlines and isotherms graphs and discussed numerically in terms of Nusselt number.

Findings
The effect of the embedded heated square block size and its location in the enclosure, nanoparticles volume fraction and the intensity of the magnetic field on flow and heat transfer are computed. Compared with the case when no heated block is embedded in the enclosure, in free convection at Ra = 106, the average local Nusselt number on the wall-mounted heaters is attenuated by 8.25%, 11.24% and 12.75% when the enclosure embraced a heated square block of side length 10% of H, 20% of H and 30% of H, respectively. An increase in Hartmann number suppresses the heat convection.

Research limitations/implications
The enhancement in the convective heat is greater when the buoyancy effect dominates the viscous effects. Placing the embedded heated block near the inlet vent, the lower temperature zone has reduced while the embedded heated block is at the central location of the enclosure, the high-temperature zone has expanded. The external magnetic field can be used as a non-invasive controlling device.

Practical implications
The numerically simulated results for heat convection of water-based copper nanofluid agreed qualitatively with the existing experimental results.

Social implications
The models could be used in designing a target-oriented heat exchanger.

Originality/value
The paper includes a comparative study for three locations of the embedded heated square. The optimal results for the centrally located heated block are also performed for three different sizes of the embedded block. The numerically simulated results are compared with the published numerical and experimental studies.
Is stress good for negotiation outcomes? The moderating effect of social value orientation
Authors: Ramirez-Marin Jimena Y. , Barragan Diaz Adrian , Acar-Burkay Sinem 
Published: December 2020

Purpose
Negotiations are often conducted under stress. Previous studies show that stress can help or hurt negotiation outcomes. This study suggests that individual differences explain these effects, and the purpose of this study is to examine the effect of social value orientation (SVO) and stress on negotiation outcomes.

Design/methodology/approach
Two experimental studies and a pilot investigate the influence of stress and SVO (prosocial vs proself) on negotiation offers and outcomes. The authors’ studies are grounded on social interdependence theory and arousal literatures to explain the effects of stress on negotiation.

Findings
Stress has a positive influence on integrative offers (S1) and joint outcomes (S2). SVO moderates the effect of stress on joint negotiation outcomes (S2), such that, under stress, prosocials fare better than proselfs.

Research limitations/implications
Managers negotiating under stress should pay attention to their own as well as the others’ SVOs. Managers could also build their negotiation teams considering this individual difference and favor the presence of prosocials in stressful negotiations.

Practical implications
The findings have practical implications for managers who are under stress on a daily basis.

Social implications
This research contributes to managers that need to understand how to reach integrative agreements under stress. This is especially important when negotiators are representatives of employees or companies, as the outcomes can affect many individuals.

Originality/value
To the best of the authors’ knowledge, this is the first study examining the relationship between stress, SVO and negotiation offers and outcomes.
An improved TEHL analysis of textured roller bearings consider various texture parameters and slip
Authors: Li Junning , Han Ka , Chen Wuge , Tang Xiaojie , Wang Qian 
Published: December 2020

Purpose
The purpose of this study is to reveal the lubrication performance of textured roller bearings under various texture size, texture depth, texture types and slip.

Design/methodology/approach
In the present study, the improved thermal elastohydrodynamic lubrication method based on the surface texturing of the textured roller bearings is proposed, and then the effect of texture size, texture depth, texture types and slip on the contact pressure, film thickness and temperature distribution are analyzed systematically.

Findings
The results show that the pressure decreases and the film thickness increases on the contact area because of the surface texturing. The temperature increases first and then decreases as the texture size increases, and then the temperature increases as the texture depth and the slip increases. Compared to circle and square texture, cross texture can obviously decrease the temperature on the contact area. The effectiveness of the proposed method is verified.

Originality/value
This study can help to reduce friction and wear of textured roller bearings.

The adaptation of anthropomorphism and archetypes for marketing artificial intelligence
Authors: Karimova Gulnara Z. , Goby Valerie Priscilla 
Published: December 2020

PurposeThis paper aims to present an exploration of possible associations between the Jungian archetypes frequently used in marketing and three well-known products based on artificial intelligence (AI), namely, Sophia, Alexa and Articoolo.Design/methodology/approachThe study conducted emotionalist interviews to gather thick data from 11 participants on how they conceptualize these AI-based products. In the absence of any existing relevant hypotheses, this paper attempts to build theory using a case study approach and qualitative analysis of interview narratives.FindingsDespite the human attributes ascribed to these products, participants were principally concerned with their purpose, efficiency and the degree of trust which they felt could be accorded to the product. Anthropomorphism emerged as significant with participants making some associations with common archetypes traditionally exploited in marketing and this suggests a possible means of enhancing consumer trust in AI products.Originality/valueLittle research has been conducted on the marketing of AI and this study presents a timely identification of some potentially significant issues. As AI is intended to mimic some aspects of human intelligence, the role of the archetype in creating a personality to enhance trust may prove crucial in securing consumer confidence.
Cynical consumer: how social cynicism impacts consumer attitude
Authors: Indibara Indirah , Varshney Sanjeev 
Published: December 2020

PurposeThis paper aims to examine the effect of social cynicism on consumer cynicism. The negative inferred motive is tested as a mediator between social cynicism and consumer cynicism; whereas, negative affectivity is tested as a moderator between social cynicism and negative inferred motive.Design/methodology/approachThe study was carried out in India using a mixed-method approach. In the first stage, a survey was conducted to test the moderated mediation model, followed by in-depth interviews in the second stage. The survey was analysed using structural equation modelling, while themes were generated from the data collected through interviews.FindingsThe study established the effect of social cynicism on consumer cynicism. Negative inferred motive mediated the relationship between social cynicism and consumer cynicism. Negative affectivity moderated the influence of social cynicism on negative inferred motive.Research limitations/implicationsWith rising anti-consumption behaviours, it is imperative to understand why consumers turn cynical towards marketers. The study indicates that consumer cynicism is influenced by previous experiences of the consumer with the society and is not merely a reaction to arm-twisting by firms. As social cynicism cannot be changed drastically, understanding how it impacts consumer cynicism would help a firm handle its marketing efforts better.Originality/valueThe study empirically validates the relationship between social cynicism and consumer cynicism. The mediating effect of negative inferred motive on consumer cynicism was also validated. The study is also the first to point out the moderating role of negative affectivity on the relationship between social cynicism and negative inferred motive.
Exploring collaboration within social housing retrofit practice for an ageing population: a single case study in the West of Scotland
Authors: Rodger Dayna , Callaghan Nicola , Thomson Craig 
Published: December 2020

Purpose
Sustainably addressing the social and economic demands from an ageing population is a major global challenge, with significant implications for policy and practice. This is resultant of the increasing demand for housing adaptations to prevent increased pressure upon acute health services. Through the lens of institutional theory, this paper aims to explore the levels of joined-up retrofit practice within a Scottish social housing provider, under a constructivist approach.

Design/methodology/approach
An exploratory single case study of a Scottish local authority was undertaken. Within this, nine key stakeholders were interviewed, taking a hierarchical approach, from director to repair and maintenance staff. Results were analysed by using Braun and Clarke’s six stages of thematic analysis.

Findings
There is a need for greater levels of integration within retrofit practice to not only improve the health and well-being of the older population but also increase efficiency and economic savings within public services. Currently, there are key issues surrounding silo-based decision-making, poor data infrastructure, power struggles and a dereliction of built environment knowledge and expertise, preventing both internal and external collaboration. However, housing, energy and health have interlinking agendas which are integral to achieving ageing in place. Therefore, there must be system-wide recognition of the potential benefits of improved cross-sector collaboration, preventing unintended consequences whilst providing socioeconomic outcomes.

Originality/value
This research provides a new perspective surrounding retrofit practice within the context of an ageing population. It highlights the requirement for improved cross sector collaboration and the social and economic cost of poor quality practice.
Is blockchain tourism’s new hope?
Authors: Irannezhad Elnaz , Mahadevan Renuka 
Published: December 2020

Purpose
Blockchain is a disruptive technology enabling distributed, encrypted, smart and secure peer-to-peer transactions. The fragmented nature of the tourism industry with a high number of contracts and transactions between several parties has security issues, disputes and delay. Although these motivate the use of blockchain, scholars have barely begun to systematically assess the value proposition of blockchain in the hospitality and tourism industry. The purpose of this paper is to examine the impacts, opportunities and challenges of blockchain in the tourism and hospitality sector. The authors present early use cases of blockchain in the tourism industry.

Design/methodology/approach
The authors conducted a multiple case-study approach and grounded this study based on the technology acceptance management literature with context-specific variables that are pivotal to the study of this topic.

Findings
This paper outlines the useful features of blockchain in the tourism industry in seven major streams and raises four future research questions. This review will enable hypotheses to be set out for consumers and producers involved in tourism to uncover potential motives and barriers to embracing blockchain.

Research limitations/implications
Blockchain is a relatively new technology, and given that all use cases are limited to the proof of concept and have not been fully adopted by the industry, empirical assessment of case studies is not feasible yet.

Originality/value
As blockchain is becoming more known and used in the tourism industry, there is a need to identify challenges, issues and concerns relevant for this industry moving forward. This paper fulfils this need and provides directions for future research.
Optimal capital structure and the debtholder-manager conflicts of interests: a management decision model
Authors: Adeoye Olanike Akinwunmi , Islam Sardar MN , Adekunle Adeshina Israel 
Published: December 2020

PurposeDetermining the optimal capital structure becomes more complicated by the presence of an agency problem. The issuance of debt as a corporate governance mechanism introduces the asset substitution problem – the agency cost of debt. Thus, there is a recognized need for models that can resolve the agency problem between the debtholder and the manager who acts on behalf of the shareholder, leading to optimal capital structure choice, and enhanced firm value. The purpose of this paper is to model the debtholder-manager agency problem as a dynamic game, resolve the conflicts of interests and determine the optimal capital structure.Design/methodology/approachAs there is no satisfactory model for dealing with the above issues, this paper uses a differential game framework to analyze the incongruity of interests between the debtholder and the manager as a non-cooperative dynamic game and further resolves the conflicts of interests as a cooperative game via a Pareto-efficient outcome.FindingsThe optimal capital structure required to minimize the marginal cost of the agency problem is a higher use of debt, lower cost of equity and withheld capital distributions. The debtholder is also able to enforce cooperation from the manager by providing a lower and stable cost of debt and a greater debt facility in the overtime framework.Originality/valueThe study develops a new dynamic contract theory model based on the integrated issues of capital structure, corporate governance and agency problems and applies the differential game approach to minimize the agency problem between the debtholder and the manager.
From third party to significant other for service encounters: a systematic review on third-party roles and their implications
Authors: Abboud Liliane , As'ad Nabila , Bilstein Nicola , Costers Annelies , Henkens Bieke , Verleye Katrien 
Published: December 2020

PurposeDyadic interactions between customers and service providers rarely occur in isolation. Still, there is a lack of systematic knowledge about the roles that different types of nontechnological third parties – that is, other customers, pets, other employees and other firms – can adopt in relation to customers and service providers during encounters. The present study aims to unravel these roles and highlight their implications for customers, service providers and/or third parties.Design/methodology/approachThis research relies on a systematic review of literature in the Web of Science using a search string pertaining to the research study’s objectives. In total, 2,726 articles were screened by title and abstract using clear inclusion and exclusion criteria, thereby extracting 189 articles for full-text eligibility. The final sample consisted of 139 articles for coding and analysis.FindingsThe analyses reveal that other customers, pets, other employees and other firms can adopt five roles: bystander, connector, endorser, balancer and partner. Each role has different implications for customers, service providers and/or third parties. Additionally, the five roles are associated with distinct constellations of the customer, the service provider and the third party. These roles and constellations are dynamic and not mutually exclusive.Originality/valueThis research contributes to the service encounter literature by providing a thorough understanding of the various third-party roles and their implications for customers, service providers and/or third parties during encounters. As such, this research sheds light on the conditions under which third parties become “significant others” in service encounters and identifies avenues for future research.
Dual foci of identification: the role of salesperson brand and organizational identification in driving brand performance
Authors: Gammoh Bashar S. , Mallin Michael L. , Pullins Ellen Bolman 
Published: December 2020

Purpose
This study aims to extend current research efforts by examining the dual role of salesperson brand and organizational identification in driving organizational citizenship behaviors, brand advocacy and ultimately brand market performance.

Design/methodology/approach
This study uses an online survey to collect data from a cross-sectional sample of salespeople. The measurement model and proposed research hypotheses are tested with SmartPLS.

Findings
Study results show that each level of identification has a stronger influence on the type of behaviors relevant to that foci of identification. That is, salesperson organizational identification has a significant and strong effect on organizational citizenship behavior while the influence of salesperson organizational identification on brand advocacy is not significant. Along the same lines, salesperson identification with the brand significantly influences brand advocacy behaviors but not their overall organizational citizenship behaviors. These empirical findings are consistent with assertions in the literature that variables (antecedents or outcomes) associated with identification at a certain level will have a stronger relationship with identification at that level.

Originality/value
Despite existing research efforts on the potential positive outcomes of salesperson identification, there is less empirical evidence regarding the dual role of brand and organizational identification. This research contributes to the current literature by proposing and empirically examining the differential (identity-matching) antecedents and outcomes of salespeople’s dual identification with the organization and the brand. Furthermore, existing research mostly focuses on organizational or sales management outcomes but not brand specifically related outcomes. Theoretically, this research draws on social identity theory to investigate the combined effect of salesperson brand and organizational identification on key brand-related outcomes. Managerially, this study provides empirically-based suggestions for managers interested in harnessing the power of identification.
