Authors: Caboni Federica , Hagberg Johan 
Published: August 2019

Purpose
The purpose of this paper is to review augmented reality (AR) within retailing by identifying, outlining and discussing definitions of AR, applications of AR that are relevant for retailers, and the value AR provides for retailers and consumers.

Design/methodology/approach
The paper is based on a review of AR research within the business-oriented literature and an overview of current AR applications within retailing.

Findings
Based on previous literature, the paper presents a synthesised definition of AR, its main elements and how it differs from virtual reality. Furthermore, it reviews and provides examples of three major types of AR applications in retailing: online web based, in-store and mobile app based. Finally, the paper identifies the specific value that AR applications may provide for consumers and retailers.

Originality/value
The paper contributes an overview of a relatively recent but rapidly emerging theme that has not yet been sufficiently reviewed. It outlines areas for further research and thus provides value for both researchers and retail practitioners.
Existentialism and tourism: new research avenues
Authors: Kirillova Ksenia 
Published: August 2019

PurposeThe purpose of this paper is to pave avenues and stimulate further research on the intersection of existentialism and tourism. This is done by presenting the overview of the topical areas that have greatly contributed to existentialism and connecting them to contemporary tourism issues.Design/methodology/approachThe paper is structured by topical areas that received significant treatment from existentialists and are deemed relevant to the contemporary tourism research and practice. It starts with the discussion of authenticity and anxiety and then proceeds to the issues of alienation, death and mortality. It ends with a review of the sections on freedom and religion. In the conclusion, broader issues related to existentialism and (urban) tourism are discussed.FindingsAside from existential authenticity/anxiety and alienation, other existential categories (mortality, death, freedom and faith) are employed in a manner that is limited, superficial or not employed at all. The potential for tourism research lies in shifting the focus from a common tourist to special populations and hosting communities and service providers, as well as in investigating existential dimensions of city experiences of both tourists and residents.Originality/valueThis is the first paper to exclusively and explicitly discuss the links between existential philosophical categories and tourism research. It is hoped that tourism scholars extend these ideas and assess their relevance across non-European and culturally and religiously diverse contexts.
Publishing Islamic economics and finance research: polemics, perceptions and prospects
Authors: Ali Syed Nazim , AlQuradaghi Bahnaz Ali 
Published: August 2019

Purpose
The purpose of this study is to examine the academic polemics, stakeholder perceptions and publishing prospects for Islamic economics and finance (IEF) research.

Design/methodology/approach
This study adopts both quantitative and qualitative methods with a view to understanding the aforementioned aspects of published IEF research. The main part of the study constitutes searching through selected databases to identify leading journals and publishing outlets for IEF research. To supplement and support the main part, the study also conducted a survey of IEF experts and interviewed major stakeholders with a view to understanding the current trends and future perspectives of IEF research. The study also attempts to bring to the fore less explored aspects of IEF research, which has the potential of shaping the future trends in both the academia and the industry.

Findings
Apart from challenges such as inadequate funding opportunities, differences in worldview, among others, the field is still in need of improvement in the quality of research despite the increasing interest in IEF research and the level of research output over the past three decades. The study also finds that IEF has yet to establish core IEF journals reporting the research findings, which creates a perception among IEF researchers that non-IEF journals have a greater academic standing than IEF journals.

Research limitations/implications
It must be highlighted that the study has been limited to specific well-known research databases; therefore, future studies may explore other leading databases such as Web of Science and examine the quality of IEF research published in journals indexed in such databases.

Practical implications
It is expected that mainstream journals in economics and finance will publish more of IEF research, which has been facilitated recently by the increasing trends of special issues of such journals dedicated to IEF research.

Originality/value
The study brings to the fore a less explored aspect of Islamic economics and finance, which has the potential of shaping future trends in both the academia and the industry.
Citizen engagement in the “post-truth era”
Authors: Andrei Andreia Gabriela , Zait Adriana , Stoian Claudia , Tugulea Oana , Manolica Adriana 
Published: August 2019

Purpose
The purpose of this study is to analyze citizen engagement and to explain the underlying mechanism that makes well-intended people to act as disinformation amplifiers in the online space. The study offers new insights to be used by knowledge management for improving society’s potential to downsize the impact of disinformation that puts both knowledge system and social trust (ST) under high pressure.

Design/methodology/approach
The study proposes an integrative research model to explain how ST and conspiracy mentality (CM) are influencing citizen engagement in public life through different forms of action that is specific to offline or online spaces. The research model and its nine hypotheses are tested based on a survey for data collection and partial least squares method for data analysis.

Findings
The study finds that both online and offline actions are mediating the positive effect of ST on citizen engagement. Yet, CM has a high impact on online actions, and it exerts a significant indirect influence on citizen engagement in this manner.

Originality/value
Revealing the mediator role of online actions in the relationship between CM and civic engagement, the paper brings novel insights on disinformation spreading. The study explains how citizen engagement can sometimes be turned against social well-being because those prone to belief in conspiracies are the perfect targets of deceivers seeking for disinformation amplifiers in the online environment.
International risk spillover in sovereign credit markets: an empirical analysis
Authors: Sabkha Saker , de Peretti Christian , Mezzez Hmaied Dorra 
Published: August 2019

Purpose
The purpose of this paper is to study the volatility spillover among 33 worldwide sovereign Credit Default Swap (CDS) markets and their underlying bond markets.

Design/methodology/approach
In contrast to prior studies, the authors incorporate heteroscedasticity, asymmetric leverage effects and long-memory features of sovereign credit spreads simultaneously through a bivariate FIEGARCH model and a Bayesian cointegrated vector autoregressive model.

Findings
Similar to the literature, the findings confirm that strong evidence of credit risk spillover between credit markets is accentuated during two recent crisis periods. However, the country-by-country analysis indicates that countries exhibit different sensitivity levels and divergent reactions to financial shocks. Further, the authors show that the bidirectional interrelationship evolves over time and across countries emphasizing the necessity of time-varying national regulatory policies and trading positions.

Originality/value
Based on a large data set that covers the recent two financial crises and using complex methods, the work focuses on sovereign tensions that have repercussions on banks’ solvency and refinancing conditions. Yet, the study is a hot topic since that during crisis periods in the financial markets, direct and indirect interconnections increase between sovereign risk and banking risk. Using new econometric approaches, the results show that each country exhibits a different behavior toward the credit risk which is relevant to both portfolio managers and policy makers. The time-varying spillover effects detected between markets are an accurate indicator of financial stability, allowing policy makers to put in place personalized economic policies. On the other hand, markets’ participants could take advantages of the results by adjusting their trading and hedging positions on the dynamic co-movements. The findings reveal, as well, that the sovereign crisis has more weakened the global financial and banking system than the subprime crisis. The authors previously tackled the cross-country contagion phenomenon in the CDS markets, and this manuscript builds on the prior study to enhance the obtained results.
The impact of SHRM on the psychological contract of employees
Authors: Roehl Maximilian Tim 
Published: August 2019

PurposeThe purpose of this paper is to provide a holistic and systematic conceptualization of the impact of strategic human resource management (SHRM) on the psychological contract. Specifically, this paper aims to explore how the alignment of HR-systems and organizational communication influences the congruence and breach of the psychological contract.Design/methodology/approachThe paper applies the signaling theory as a lens to develop a typology of four “ideal types” of SHRM configurations, each characterized by differences in the alignment of the HR-system and communication quality. Based on this typology, the influence of these different SHRM configurations on the congruence and breach of the psychological contract is being proposed.FindingsThe typology shows that the alignment of HR-systems and communication quality impact differently on the formation and breach of the psychological contract. It highlights that employees require both, highly aligned HR-systems and a high-quality communication to form congruent contract perceptions.Originality/valueThe configurational arguments embedded in the typology allow the conceptualization of the interrelationships between the alignment of HR-systems, organizational communication and the congruence and breach of the psychological contract. The propositions derived from the typology can guide research on SHRM as an antecedent of the psychological contract and shed light on the role of the psychological contract as a linking mechanism between SHRM and the employees’ reactions.

The ROI-based approach to HR analytics presented in this study provides a robust tool to compare and contrast different dilemma and associated value that can be derived from conducting the various types of HR analytics projects.

Originality/value
A framework is presented that aggregates the findings and clarifies how various HR analytics tools influence ROI and how these relationships can be explained.
A review on fibre reinforced composite printing via FFF
Authors: Ferreira Isaac , Machado Margarida , Alves Fernando , Torres Marques António 
Published: August 2019

Purpose
In industry, fused filament fabrication (FFF) offers flexibility and agility by promoting a reduction in costs and in the lead-time (i.e. time-to-market). Nevertheless, FFF parts exhibit some limitations such as lack of accuracy and/or lower mechanical performance. As a result, some alternatives have been developed to overcome some of these restrictions, namely, the formulation of high performance polymers, the creation of fibre-reinforced materials by FFF process and/or the design of new FFF-based technologies for printing composite materials. This work aims to analyze these technologies.

Design/methodology/approach
This work aims to study and understand the advances in the behaviour of 3D printed parts with enhanced performance by its reinforcement with several shapes and types of fibres from nanoparticles to continuous fibre roving. Thus, a comprehensive survey of significant research studies carried out regarding FFF of fibre-reinforced thermoplastics is provided, giving emphasis to the most relevant and innovative developments or adaptations undergone at hardware level and/or on the production process of the feedstock.

Findings
It is shown that the different types of reinforcement present different challenges for the printing process with different outcomes in the part performance.

Originality/value
This review is focused on joining the most important researches dedicated to the process of FFF-printed parts with different types reinforcing materials. By dividing the reinforcements in categories by shape/geometry and method of processing, it is possible to better quantify performance improvements.
The influence of a process interruption on tensile properties of AlSi10Mg samples produced by selective laser melting
Authors: Hammond Vincent , Schuch Michael , Bleckmann Matthias 
Published: August 2019

Purpose
The purpose of this paper is to investigate the influence of a process interruption on the tensile properties of AlSi10Mg samples produced by selective laser melting (SLM).

Design/methodology/approach
Using identical processing parameters, cylindrical samples were produced in either a continuous or interrupted SLM build operation. The tensile properties and microstructure of the samples were determined as a function of process type as well as orientation.

Findings
All samples produced in this paper displayed superior tensile properties to those produced in high pressure die casting. In general, the samples produced in the continuous build process had higher strengths and microhardness than those produced in the interrupted process. However, while most samples displayed random failure locations, the vertical samples produced in the interrupted build process showed a strong tendency for localized failure in the vicinity of the stoppage plane.

Originality/value
This paper demonstrated that samples produced in an interrupted build process tend to have poorer mechanical properties than those produced in a continuous process. Together, these observations highlight the importance of a suitable technique for restarting and completing an interrupted build process to ensure the production of high quality components.
Investigation on moist silica sand’s circulation for sand mold printing with line-forming
Authors: Zhao Donghua , Guo Weizhong , Zhang Baibing , Gao Feng 
Published: August 2019

Purpose
This paper aims to investigate the circulation of moist silica sand to provide appropriate feeding modes and references for designing the coating device when printing sand mold with line-forming.

Design/methodology/approach
First, this paper briefly introduces sand mold printing with line-forming and the circulation problem brought by moist silica sand. The outlet may be choked due to poor flowability and solidification characteristic, resulting in poor dimensional tolerance and even production failure. Then, based on circulation modeling, a series of feeding modes is proposed to guarantee adequate feeding, avoid solidification and ensure successful fabrication. Finally, the GUI of control software is developed, including slicing, path planning and the function of virtual printing.

Findings
Several feeding modes of moist silica sand are put forward to avoid the choke.

Research limitations/implications
The authors will further investigate the flowability of furan no-bake sand based on experiments.

Originality/value
This paper is going to provide references for the novel design of nozzle, prototype and sand mold printing, influencing significantly on mold manufacturing and the casting industry. This research applies equally to equipment having the circulation of high moist particles with solidification features.
Thermal cycling, microstructure and tensile performance of PLA-PHA polymer printed using fused deposition modelling technique
Authors: Guessasma Sofiane , Belhabib Sofiane , Nouri Hedi 
Published: August 2019

Purpose
This paper aims to investigate the effect of printing temperature on the thermal and the mechanical behaviour of polylactic acid (PLA)-polyhydroxyalkanoate (PHA) blend printed using fused deposition modelling (FDM).

Design/methodology/Approach
Because of the use of an infra-red camera, thermal cycling during the laying down is quantified. In addition, X-ray micro-tomography is considered to reveal the microstructural arrangement within the three-dimensional printed material. Tensile loading conditions are used to derive Young’s modulus, tensile strength and fracture toughness, and relate these to the printing temperature. Finite element computation based on three-dimensional microstructure information is used to predict the role of defects on the tensile performance.

Findings
The results show a remarkable cohesive structure of PLA-PHA, particularly at 240°C. This cohesive structure is explained by the ability to ensure heat accumulation during laying down as evidenced by the nature of thermal cycling. The printing temperature is found to be a key factor for tuning the ductility of the printed PLA-PHA allowing full restoration of tensile strength at high printing temperature.

Originality/value
This study reports new results related to the thermo-mechanical behaviour of PLA-PHA that did not receive much attention in three-dimensional printing despite its potential as a candidate for pharmacological and medical applications. This study concludes by a wide range of possible printing temperatures for PLA-PHA and a remarkable low porosity generated by FDM.
Information literacy in Utah: a state of the state
Authors: Diekema Anne R. , Gerrity Caitlin , Mitchell Paula 
Published: August 2019

Purpose
Ideally, information literacy instruction is sequenced throughout students’ academic careers, reinforcing and building on earlier instruction. The purpose of this exploratory study is to identify structural problems that potentially impact student learning. This research surveyed school librarians and academic instruction librarians along the K-20 pipeline to capture information about their instruction programs, their pedagogical approaches and their perceptions on student information literacy skills at points of transition.

Design/methodology/approach
The study uses a 58-item survey instrument to capture the perceptions on elements of information literacy instruction from school librarians and academic instruction librarians in the state of Utah. The exploratory survey generated 255 eligible responses.

Findings
The study identifies several areas where the information literacy pipeline has challenges: staffing, scheduling, curriculum integration, teacher collaboration and student assessment. Suggestions for improvement include providing educational support for paraprofessionals, facilitating cross-institutional collaboration and creating a scope and sequence document that spans the entire educational spectrum paired with specifically teaching for transfer.

Research limitations/implications
The study was limited to surveying the perceptions of library employees who teach students information literacy as part of a school or university. Study findings imply that better support for information literacy learners requires increased collaboration across the pipeline.

Originality/value
Information literacy education is often siloed – in the way it is taught, studied and discussed. This research is unique in that it explores the information literacy pipeline as a whole, as each level of instruction is related to the next and studying a single section might obscure larger issues.

Authors: Maxson Bronwen K. , Neely Michelle E. , Roberts Lindsay M. , Stone Sean M. , Lowe M. Sara , Macy Katharine V. , Miller Willie 
Published: August 2019

PurposeThe purpose of this paper is to discuss different strategies for implementing peer teaching as well as different roles for peer teachers in both academic libraries and writing-intensive courses. It explores connections to critical pedagogy, sociocultural theory, open educational practices and high-impact practices.Design/methodology/approachThe methodology for implementing the three scenarios discussed in the paper differs widely. All approaches include some form of student feedback through focus groups, exit surveys or end-of-class assessments.FindingsIn both library and writing program settings, students have experience with and a favorable opinion of peer-assisted learning strategies.Practical implicationsThese case studies provide concrete examples of how to develop different types of peer teaching interventions. The cases also detail benefits as well as challenges to implementation.Social implicationsProviding opportunities for peers to lead through teaching others has the potential to boost an individual’s sense of confidence, leadership and improve their own learning, as well as give students’ experiences to build upon and apply to their everyday lives and future careers.Originality/valueWhile peer teaching is widely implemented in many disciplines, such as science, technology, engineering and medicine, its adoption in academic libraries has sometimes been viewed as controversial. This case study adds to the body of literature demonstrating that peer teaching is possible and desirable.
Online active-learning: information literacy instruction for graduate students
Authors: Parramore Sarah 
Published: August 2019

Purpose
The purpose of this paper is to describe the challenges of teaching information literacy online to graduate students and evaluate software that supports using active learning techniques.

Design/methodology/approach
This conceptual paper analyzes different software tools and their functionality to aid in active learning, as well as describes elements of online teaching that facilitate active learning for information literacy.

Findings
Although software serves as the delivery tool, there is not one standalone product that provides all the needed aids to conduct active learning. Many other digital tools are needed in addition to the tutorial software to create active learning activities.

Practical implications
This paper provides activities and ideas to incorporate into the online information literacy session that contain active learning elements.

Originality/value
Although there is a wealth of literature about active learning of information literacy, very little surrounds teaching it online to graduate students. This paper focuses on this specific element of teaching information literacy through active learning methods in an online environment to graduate students.
