Social vulnerability and local level assessments: a new approach for planning
Authors: Mendes José Manuel , Tavares Alexandre Oliveira , Santos Pedro Pinto 
Published: January 2020

PurposeThe purpose of this paper is to present a new index of social vulnerability (SV), based on local level data [statistical blocks (SBs)]. This same methodology was applied before at the municipal level, which is a level of analysis that under-evaluates local spots of high SV, by one side, and generalizes the coverage of support capacity equipment and infrastructure. The geographical level of detail of the input data allows to overcome those limitations and better inform infra-municipal risk practitioners and planners.Design/methodology/approachThe assessment of SV in this paper adopts an inductive approach. The research context of this conceptual and methodological proposal derived from the need to operationalize the concept of SV as a planning tool. This approach required to distinguish between the components of criticality and support capability, as their assessment provides knowledge with distinct applications in risk management. The statistical procedure is based on principal components analysis, using the SB as the unit of analysis.FindingsSupport capability acts as a counter-weight of criticality. This understanding is well illustrated in the mapping of each component and the final score of SV. The methodological approach allowed to identify the drivers of criticality and support capability in each SB, aiding decision-makers and risk practitioners in finding the vulnerability forcers that require more attention (public or private social equipment, housing policies, emergency anticipatory measures, etc.).Originality/valueAn original approach to SV assessments is the consideration of the components of criticality and support capability. The results allow for the definition of adapted and specific strategies of risk mitigation and civil protection measures to distinct types of risk groups and by different stakeholders and risk practitioners. By predicting the impact and the recovery capacity of communities, the results have applicability in several fields of risk governance as, for example, risk communication and involvement, social intervention (health, education and housing), emergency response, contingency planning, early warning and spatial planning.
Dynamic connectedness between Bitcoin and equity market information across BRICS countries
Authors: Dahir Ahmed Mohamed , Mahat Fauziah , Amin Noordin Bany-Ariffin , Hisyam Ab Razak Nazrul 
Published: January 2020

Purpose
Recent trends and developments in Bitcoin have led to a proliferation of studies that analyzed the Bitcoin returns and volatility; however, the volatility connectedness between Bitcoin and equity market information in emerging countries quietly remains scarce. Regarding this deficiency, the purpose of this paper is to examine the dynamic connectedness between Bitcoin and equity market information.

Design/methodology/approach
Daily data from January 1, 2012 to May 31, 2018 are used. The paper applies a novel time-varying parameter vector autoregression (TVP-VAR) model extended by Antonakakis and Gabauer (2017). This model addresses the biases in coefficient estimates, considering innovations from sources of time variation.

Findings
The findings reveal that the volatility transmission of Bitcoin return is not an important source of shocks of market returns in Brazil, Russia, India, China and South Africa (BRICS), suggesting that Bitcoin return contributes less volatility to equity market information. The results further show that Bitcoin is the main receiver of volatility while market price risk is the dominant transmission catalysts for innovations in the rest of the stock market returns.

Practical implications
Important implications can be derived from these findings, signaling of the demand to develop and implement volatility connectedness policy measures in order to guarantee the stability of financial assets. However, the most significant limitation lies in the fact that the analysis of this paper is restricted to the volatility connectedness between Bitcoin and equity market information in BRICS countries.

Originality/value
By acknowledging the wide range of econometric models, the paper uses TVP-VAR model because this methodology is a useful and relevant tool in modeling the volatility connectedness of financial variables, thus providing meaningful information to policy makers and international investors.
Gaze behaviour in front-of-shelf orientation
Authors: Ladeira Wagner , Santini Fernando de Oliveira , Jardim William Carvalho 
Published: January 2020

PurposeThis study was predicated on gaze behaviour in front-of-shelf orientation. The purpose of this paper is to analyse the effect of the presence (absence) of competing brands on consumer attention in front-of-shelf orientation. The effects on visual attention investigated on the shelf were eye scan path of the total available area, information acquisition in extremities and mental effort.Design/methodology/approachTwo experiments were performed using eye-tracking technology. The first study was conducted in a closed and static environment. The second study was performed in an open and dynamic environment. In these studies, the authors used, as an independent variable, the arrangement of brands on shelves (presence vs absence of competing) and evaluated the variations in the visual attention through three dependent variables: eye scan path of the total available area, information acquisition in extremities and mental effort.FindingsThree hypotheses were tested. The first hypothesis confirmed that scenarios of competitive brands are rather composed of natural complex scenes, so there is a greater number of eye fixations needed to identify and locate objects. In addition, the second hypothesis demonstrated that, in scenarios of competitive brands, there is an acceleration of information acquisitions causing an increase in peripheral vision at the ends of the shelf. Finally, the third hypothesis demonstrated that the presence of a greater attention effort in the scenario of competing brands was verified, since the mental effort variables (revisiting the shelf, noting and re-examining) were greater than in the scenario of non-competing brands.Research limitations/implicationsLimitations of this study may be associated with the absence of top-down factors and a lack of results associated with evaluation and verification phases.Originality/valueGaze behaviour is susceptible to the information derived from the absence and presence of competing brands.
Do women in board represent less corporate tax avoidance? A moderation analysis
Authors: Riguen Rakia , Salhi Bassem , Jarboui Anis 
Published: January 2020

PurposeThe purpose of this paper is to empirically examine how women in board represent moderates the relationship between audit quality and corporate tax avoidance.Design/methodology/approachThe study is based on a sample consisting of 270 UK firms over the 2005–2017 period. This study is motivated by moderating regression analysis.FindingsThe results show that audit quality influences the corporate tax avoidance. Audit quality measured by two proxies audit specialization and audit fees has a negative effect on corporate tax avoidance. Board gender diversity “BGD” moderates the relationship between audit quality and tax avoidance. The impact of the BGD level increases as the presence of woman in the board escalated from 40 to 60 percent but, then, weakens at 10 percent level.Practical implicationsThe findings may be of interest to the academic researchers, practitioners and regulators who are interested in discovering relation between audit quality and tax avoidance with the presence of woman in the board. This study should be of interest to tax policymakers concerned about declining corporate tax revenues.Originality/valueThis paper extends the existing literature by examining the moderating effect of BGD on the relation between audit quality and corporate tax avoidance using the sensitivity analysis.
Investigation of different tribological systems during full forward impact extrusion of aluminum alloy EN AW 6082
Authors: Müller Martina , Hild Rafael , Trauth Daniel , Bergs Thomas 
Published: January 2020

Purpose
The modification of the tribological system is an essential aspect of the implementation of resource-saving processes in cold forming. As a result, the focus of this contribution is the influence of the tribological system on the full forward impact extrusion of aluminum alloy EN AW 6082 (T6) with regard to reduction of friction and wear.

Design/methodology/approach
The investigations included a variation of lubricant and die treatment. Friction, wear and the mean arithmetic height Sa were used as evaluation criteria. The aim was to find a suitable die surface treatment and a suitable lubricant on the basis of the evaluation criteria.

Findings
The experiments indicated that each of the selected tribological systems prevents physical metallic contact between tool and workpiece and thus prevents the formation of wear. Nevertheless, differences were found in the areas of smoothing of workpiece surfaces and adhesive strength of lubricants.

Originality/value
As general cause effect relationships between die coating and lubricant are not known in the field of bulk metal forming of aluminum, fundamental investigations are described below. The investigations focus on the influence of the material and the tribological system on friction as well as wear.

ICT in social protection schemes: deinstitutionalising subsidy-based welfare programmes
Authors: Masiero Silvia , Prakash Amit 
Published: January 2020

PurposeWhile the potential of information and communication technology (ICT) for poverty reduction is widely recognised, limited knowledge exists on its use in the social protection schemes devised for the world’s poor. Drawing on the institutionalist vision of IS development and organisational change put forward by Avgerou (2000), the authors propose that computerisation of these schemes entails two processes, namely, the progressive affirmation of ICT innovation and a shift in the programmes' organisational structure, which moves from a subsidy-based model to one grounded on direct cash transfers. The purpose of this paper is to illustrate how the role of ICT in anti-poverty schemes results from concomitance of such processes.Design/methodology/approachThe paper draws on a study of the public distribution system (PDS), the main food security scheme in India, as it is being computerised in the state of Karnataka. Following an interpretive case study methodology, it investigates the ongoing computerisation of the Karnataka PDS through a combination of back-end and front-end technologies, based on biometric recognition of the programme’s users.FindingsThe data reveal that transformation of the PDS results from the simultaneous processes of institutionalisation of ICT innovation and deinstitutionalisation of the extant state-led subsidy scheme, in favour of a leaner social protection system centred on cash transfers to beneficiaries. This illustrates the point that ICT innovation is intertwined with the decline of an extant social welfare structure and the rise of a new one, based on the direct transfer of benefits.Originality/valueThe paper offers a new theoretical perspective to illuminate the computerisation of anti-poverty programmes, a phenomenon that affects the entitlements of millions of poor people on a global scale. In parallel, it draws practical implications for countries embarking on the digitalisation of their social protection schemes.
Investigating open innovation strategies and firm performance: the moderating role of technological capability and market information management capability
Authors: Liao Suqin , Fu Lihua , Liu Zhiying 
Published: January 2020

PurposeThis study aims to assess how firm functional capability moderates the relationship between two types of open innovation and performance, with a special focus on the role of technological capability and the join effect market information management capability. This paper develops and tests a research model, which assesses how the performance implications of two open innovation forms are shaped by the technological capability and how such an effect is contingent on market information management capability.Design/methodology/approachSurvey data were collected from 238 Chinese high-tech enterprises. Structural equation modeling and linear regression were used to test the data. Then, the main research questions were answered.FindingsEmpirically results show that technological capability strengthens the influence of inbound open innovation on firm performance. However, the moderate effect of technological capability on the relationship between outbound open innovation and firm performance remains unsupported. A higher technological capability with a high level of market information management capability increases the efficacy of outbound open innovation in gaining superior performance. Additional analysis shows that when firms implement inbound activities and possess a strong technological capability, they will achieve higher performance if they possess a moderate level of market information management capability, compared with a high or low level.Originality/valueThis paper provides new evidence on the benefits of different open innovation strategies on firm’s performance and, more importantly, the specific firm-level contingencies (technological capability and market information management capability) under which these benefits are more likely to be enhanced. It clarifies what the capabilities are and how they interact to foster the robust open innovation strategies, which sheds new light on the boundary conditions that affect the open innovations–firm performance relationship.
Playful interfaces to the archive and the embodied experience of data
Authors: Hendery Rachel , Burrell Andrew 
Published: January 2020

Purpose
The purpose of this paper is to demonstrate the possibility for the galleries, libraries, archives and museums sector to employ playful, immersive discovery interfaces for their collections and raise awareness of some of the considerations that go into the decision to use such technology and the creation of the interfaces.

Design/methodology/approach
This is a case study approach using the methodology of research through design. The paper introduces two examples of immersive interfaces to archival data created by the authors, using these as a springboard for discussing the different kinds of embodied experiences that users have with different kinds of immersion, for example, the exploration of the archive on a flat screen, a data “cave” or arena, or virtual reality.

Findings
The role of such interfaces in communicating with the audience of an archive is considered, for example, in allowing users to detect structure in data, particularly in understanding the role of geographic or other spatial elements in a collection, and in shifting the locus of knowledge production from individual to community. It is argued that these different experiences draw on different metaphors in terms of users’ prior experience with more well-known technologies, for example, “a performance” vs “a tool” vs “a background to a conversation”.

Originality/value
The two example interfaces discussed here are original creations by the authors of this paper. They are the first uses of mixed reality for interfacing with the archives in question. One is the first mixed reality interface to an audio archive. The discussion has implications for the future of interfaces to galleries, archives, libraries and museums more generally.
Coordination to choreography: the evolution of humanitarian supply chains
Authors: Grange Ray , Heaslip Graham , McMullan Caroline 
Published: January 2020

Purpose
The purpose of this paper is to identify how coordination has evolved in humanitarian logistics (HL), what were the triggers for change and how have they been facilitated.

Design/methodology/approach
This paper applies a systematic literature review of academic journals.

Findings
This is the first paper to discuss the concepts of network orchestration and choreography in a humanitarian context. The research revealed that network coordination has moved on in the commercial sector to include orchestration and now, choreography concepts which have not been tested in HL literature. This reveals a lag exists between HL research and practice.

Research limitations/implications
This paper represents an exploratory study and provides the basis for further research on the concepts of orchestration and choreography in HL. The paper sets a research agenda for academics.

Practical implications
This paper is the first to discuss the concepts of network orchestration and choreography in a humanitarian context.

Originality/value
The areas of orchestration and choreography have received limited consideration within the humanitarian aid logistics literature to date. This paper is designed to redress this shortfall. As a result, it is hoped that it will act as a catalyst for further research and to widen and deepen the resultant debate with a view to improving the outcome for those affected by current and future disasters.
Shari’ahsupervisory board’s size impact on performance in the Islamic banking industry
Authors: Nomran Naji Mansour , Haron Razali 
Published: January 2020

PurposeThis study aims to empirically examine whether there is any optimalShari’ahsupervisory board’s (SSB) size that maximizes performance of Islamic banks (IBs). Apparently, IBs adopt different SSB size based on their different regulations across jurisdictions, and then it is still questionable whether there is any optimal SSB size that can fit all and be recommended to IBs.Design/methodology/approachThe paper investigates the impact of different SSB size on IBs performance using a sample of 113 banks over 23 countries for the period 2007-2015 based on the generalized method of moments estimator.FindingsThe empirical evidence documented in this study strongly highlights the importance of small SSB size in enhancing the performance of IBs as compared to the large board size. The findings confirm that the SSB size of IBs should neither be lesser than three nor greater than six. More specifically, it is found that the optimal SSB size seems to be five.Research limitations/implicationsFirst, the study does not investigate whether the findings are constant during crisis and non-crisis periods. Second, the optimal SSB size in IBs should be confirmed from the risk-taking perspective besides performance.Practical implicationsFor both the IBs and the regulators, they should give due importance to small SSB size as an important element for improving the IBs performance. It is strongly recommended for the IBs to have a SSB size between three and six, and five is the most recommended. The Accounting and Auditing Organization for Islamic Financial Institutions also should revise their existing standards that only suggest the minimum SSB size of three to include the maximum size of six and the optimal size of five.Originality/valueDespite the SSB size plays an important role in affecting the performance of IBs, it seems there are no empirical studies attempting to address whether there is any optimal SSB size that can enhance the IBs performance so far.
Investigating broker centrality in innovation-driven networks
Authors: Idiagbon-Oke Moronke , Oke Adegoke 
Published: January 2020

PurposeIn contrast to the vertical supply chain structure, firms are increasingly engaging in horizontal inter-firm collaborations to develop new technologies, products and services, yet, little is known about factors that influence the governance mechanism and performance of such collaborative projects. The purpose of this paper is to investigate how different factors affect the role or the centrality of the governing mechanism (the broker) in inter-firm collaborative networks.Design/methodology/approachUsing a case study method approach, this paper studies three dynamic networks comprising firms that are not in a traditional supply chain relationship. The networks comprised firms engaged in the development of different aspects of an innovative automotive technology.FindingsThe study finds that broker’s centrality varies over time and is directly related to project performance; network structure and perceived broker power are related to broker centrality in dynamic networks. The more loosely connected a network is (open network), the more the degree of broker centrality. The higher the degree of expert power that a broker is perceived to possess, the higher is the degree of broker centrality.Originality/valueInvestigating governance mechanism and determinants of network outcomes in inter-firm collaboration for new product development represents a departure from the traditional studies on similar phenomena in vertically structured supply chain arrangements; thus, contributes to the literature on innovation in inter-firm arrangements. Understanding how the salient factors contribute to performance at the network level builds on firm level and dyadic level of analysis or focus of previous studies.
