Rheology effect and enhanced thermal conductivity of diamond/metakaolin geopolymer fabricated by direct ink writing
Authors: Wang Yushen , Xiong Wei , Tang Danna , Hao Liang , Li Zheng , Li Yan , Cheng Kaka 
Published: May 2021

Purpose
Traditional simulation research of geological and similar engineering models, such as landslides or other natural disaster scenarios, usually focuses on the change of stress and the state of the model before and after destruction. However, the transition of the inner change is usually invisible. To optimize and make models more intelligent, this paper aims to propose a perceptible design to detect the internal temperature change transformed by other energy versions like stress or torsion.

Design/methodology/approach
In this paper, micron diamond particles were embedded in 3D printed geopolymers as a potential thermal sensor material to detect the inner heat change. The authors use synthetic micron diamond powder to reinforced the anti-corrosion properties and thermal conductivity of geopolymer and apply this novel geopolymer slurry in the direct ink writing (DIW) technique.

Findings
As a result, the addition of micron diamond powder can greatly influence the rheology of geopolymer slurry and make the geopolymer slurry extrudable and suitable for DIW by reducing the slope of the viscosity of this inorganic colloid. The heat transfer coefficient of the micron diamond (15 Wt.%)/geopolymer was 50% higher than the pure geopolymer, which could be detected by the infrared thermal imager. Besides, the addition of diamond particles also increased the porous rates of geopolymer.

Originality/value
In conclusion, DIW slurry deposition of micron diamond-embedded geopolymer (MDG) composites could be used to manufacture the multi-functional geological model for thermal imaging and defect detection, which need the characteristic of lightweight, isolation, heat transfer and wave absorption.

Authors: Fatima Tehreem , Bilal Ahmad Raza , Imran Muhammad Kashif , Sarwar Ambreen 
Published: May 2021

PurposeOstracism is a subjective and relative concept that renders itself to multiple manifestations and context-specific outcomes. Therefore, this study identified specific behaviours that are perceived as workplace ostracism by teaching faculty of Pakistani Higher Educational Institutions (HEIs). Building on belongingness theory, the ramifications of ostracism on psychological well-being are outlined along with the context-specific factors that shape these outcomes.Design/methodology/approachA phenomenological approach was adopted, and 30 semi-structured interviews from the teaching faculty of HEIs in Lahore, Pakistan, were conducted. The transcribed interviews were coded, and an inductive thematic analysis via NVivo 12 Plus software was used to generate themes and sub-themes.FindingsFive behaviours, i.e. biased treatment, exclusion from formal and informal interactions, interpersonal alienation, delayed sharing or hiding of knowledge, lack of work-related, social and emotional support constituted the acts of ostracism in studied HEIs. The psychological well-being of faculty suffered in terms of negative emotions, reduced job, career and life satisfaction in their work and family life. The contextual factors deciding the intensity of outcomes resulting from workplace encompassed head of department (HOD) support, pay, friendly relations, fear of confrontation, alternative job options and designation of faculty members.Originality/valueThis research is a pioneer in using an in-depth phenomenological approach to define a behavioural typology of ostracism in academia. Moreover, a much needed holistic outcome of psychological well-being is explored in work and non-work domains and further elucidated in light of context-specific factors.
An interaction effect of perceived government response on COVID-19 and government agency’s use of ICT in building trust among citizens of Pakistan
Authors: Mansoor Mahnaz 
Published: May 2021

Purpose
Among the digital age players, one of the fastest-growing digital channels is social media. In the past few years, developing nations’ government entities and political parties started using social media platforms to broadcast important information regarding decisions made at the state level. Pakistan is among those countries. Therefore, this study aims to empirically investigate the impact of the government agency’s provision of quality information on social media in establishing trust among citizens of Pakistan in a government agency with an underlying mechanism of citizens’ perception about agency’s transparency and responsiveness along with moderating role of perceived government response on COVID-19.

Design/methodology/approach
Data was collected from 542 social media followers of the Associated Press of Pakistan (a government news agency) and was analysed using measurement and structural models by using SmartPLS 3.3.0.

Findings
Results revealed that the interactive effect of government response on COVID-19 and government agency’s provision of quality information on social media strengthens the association of government presence on social media with citizens’ perception of the agency’s transparency and responsiveness and their trust in the agency.

Practical implications
Furthermore, the current study will contribute to the body of knowledge regarding the government agency’s use of information and communication technology and the government’s resultant response on COVID-19.

Originality/value
An extensive study of the literature revealed a gap available regarding the mediatory role of the citizens’ perception about agency’s transparency and responsiveness in between the association of government agency’s provision of quality information on social media and citizens’ trust in the government agency. Also, to the best of the author’s knowledge, no study to date has investigated the moderating role of government response on COVID-19 in between the relationship of government agency’s provision of quality on social media and citizens’ trust in the government agency and their perception about agency’s transparency and responsiveness. Thus, the current study aimed to address these existing gaps in the literature.

Authors: Pang Beibei , Gou Juanqiong , Afsarmanesh Hamideh , Mu Wenxin , Zhang Zuopeng 
Published: May 2021

Purpose
Leading-edge information and communication technology provides the base to facilitate obtaining, interoperating and federating shared metadata knowledge in collaborative networks from multiple heterogeneous data sources. The purpose of this study is to develop a methodology and a set of mechanisms to support this task in the collaborative environment.

Design/methodology/approach
In this paper, the authors first identify and capture four main typical sources to find or generate metadata knowledge for shared data in emerging networked environments, including existing well-designed metadata, the typical ones are relational schemas of existing databases in the environment; fragmented metadata sources, i.e. metadata that can be realized from existing mission statements and example application scenarios in the environment, usually characterized by their fragmented, lightweight and behavior-intensive features; extracting metadata for simple labeled unstructured data, e.g. textual communications among its stakeholders; and semantic constraints on metadata, e.g. the temporal data behavior could be generated from governance policies in the environment. Second, the authors introduce their systematic methodology to the unification of the resulted metadata consisting of four semiautomated unification steps that gradually develops and enhances a unified ontology for the environment, formalized in web ontology language.

Findings
The methodology steps and their corresponding mechanisms are described and exemplified in detail in this paper. Furthermore, this paper presents the outcome of applying the authors’ methodology to an example emerging case through the generation of a unified ontology for that environment.

Originality/value
The addressed example application area is a real case in the field of higher education in China and therefore serves as a proof of concept and verification of the effectiveness of the authors’ proposed approach.
Customer’s digital advocacy: the impact of reviews and influencers in building trust for tourism and hospitality services
Authors: Dutta Kirti , Sharma Kirti , Goyal Terjani 
Published: May 2021

Purpose
Marketers are focusing on the need for customer advocacy to influence other customers and drive consumption. The purpose of this paper is to explore whether online or digital advocacy influences customer decision-making related to the purchase of travel and tourism services. This paper will also identify the categories of influencers that stimulate purchase for travel and tourism. Influencers do want to know the kind of information customers are looking for.

Design/methodology/approach
This paper is based on a primary survey of travelers to understand their degree of dependence on online reviews while making hospitality consumption-related decisions.

Findings
This paper looks at both influencer marketing and online reviews by consumers to understand consumption toward advocated brand. Influencers who are perceived as unbiased in their viewpoints are trending on social media. Consumers gain trust in reviews that disclose reviewer information, number of relevant reviews are present over a period and presence of both unbiased positive and negative recommendations related to the establishment and prices versus performance.

Practical implications
Marketers and influencers alike can gain from the factors influencing consumer trust toward online advocacy and reviewed information.

Originality/value
Research is relevant for all stakeholders as it highlights the fact that consumers are looking at online reviews and one does not have to be a famous personality to influence purchase. It is relevant for influencers, as it highlights reasons for trust and various information cues that consumers are looking for. Research also gives perspective to influencers to refine online strategy and gain trust of more followers.
Kiosks as self-service technology in hotels: opportunities and challenges
Authors: Gupta Kanika , Sharma Sanjay 
Published: May 2021

Purpose
The advent of technology has played a crucial role in changing the landscape of the hospitality sector. One such technology is the adoption and installation of kiosks in hotels. While some of the hotels have adopted and installed kiosks for self-services, the other hotels are still not very comfortable with the idea of self-service. This paper aims to explore the possibilities, challenges and issues that hoteliers face while dealing with self-service kiosks, it further investigates the customer’s perspective and its benefits to the end-user.

Design/methodology/approach
This study has assimilated data from hotel managers and executives that have deployed kiosks. This study involved the collection of primary data through structured interviews. Eight different hotels from the UK and India have been compared and analyzed to formulate subcategories to answer the research questions. A total of 200 customers from both the countries were approached to get the primary data; the customers were from the same hotel where the hotel executives and managers were interviewed.

Findings
The customers accepted Kiosks as easy to use, fast to run, fun to operate, but, lacking human interaction and counter language issues were simultaneously discussed. Kiosks have been emerging as self-service technologies in hotels and play a key role in reducing bottlenecks in hotel operations. The technology anxiety and counter service argument is merely a transition phase that will fade away gradually. However, the financial feasibility and the level of adoption depend upon the level of operations and the demographic characteristics of customers.

Research limitations/implications
The dependence of data from the person interviewed and their biases for answers, along with the trust and credibility of the data available online remain the biggest challenge. Increasing the sample size and more participation from different hotels would have made the study even more useful.

Originality/value
The research seeks to eliminate the gap in research by studying both the hotels' and the customers' perspective toward kiosks deployment in hotels. The results of the study would highlight the potential challenges being faced by hotel operations and opportunities they perceive in kiosks installation, therefore the results are very useful for hotels, hoteliers, academicians and students pursuing a career in the hospitality sector.
Analysis of pore water pressures in an earth dam under operating conditions (case of Taksebt Dam, Algeria)
Authors: Terbouche Farid , Hamza Ali , Gabi Smail 
Published: May 2021

Purpose
The purpose of this paper is the analysis of the dissipation of pore water pressures in the core of an earth dam, under the effect of water level fluctuations in the reservoir under operating conditions, taking into account the partial emptying and filling.

Design/methodology/approach
The Taksebt Dam, Tizi-Ouzou, Algeria was chosen as a case study, using a two-dimensional transient finite element numerical model. The GeoStudio calculation software is used through the SEEP/W. The latter takes into account the flow in the saturated and unsaturated zone, the formulation of SEEP/W allows the analysis of the dissipation of pore water pressures in the dyke. Starting from the maximum level of the reservoir, at least one cycle of partial emptying-filling was modelled over an eight-year operating period from 2011 to 2019. The input variables were the water level variation curve, material properties and boundary conditions.

Findings
It can be concluded that the numerical results obtained from the simulation model on the different points studied, namely, the pore water pressures are satisfactory as long as they are close to those recorded in the field by the pore pressure cells with an average error not exceeding 10% except for some measurements where the error is 20%. When the water level in the reservoir varies, the pore water pressures vary and their behaviour follows these fluctuations. Some points in the dam are affected by negative pore water pressures. No abnormal situations have been detected pore water pressures.

Originality/value
The numerical results of the simulation are analysed and validated against actual pore pressure cell measurements under operating conditions.
HSI-GCN: hyperspectral image classification algorithm based on Gabor convolutional networks
Authors: Youcef Moudjib Houari , Haibin Duan , Zhang Baochang , Ahmed Ghaleb Mohammed Salah 
Published: May 2021

Purpose
Hyperspectral imaging (HSI) systems are becoming potent technologies for computer vision tasks due to the rich information they uncover, where each substance exhibits a distinct spectral distribution. Although the high spectral dimensionality of the data empowers feature learning, the joint spatial–spectral features have not been well explored yet. Gabor convolutional networks (GCNs) incorporate Gabor filters into a deep convolutional neural network (CNN) to extract discriminative features of different orientations and frequencies. To the best if the authors’ knowledge, this paper introduces the exploitation of GCNs for hyperspectral image classification (HSI-GCN) for the first time. HSI-GCN is able to extract deep joint spatial–spectral features more rapidly and accurately despite the shortage of training samples. The authors thoroughly evaluate the effectiveness of used method on different hyperspectral data sets, where promising results and high classification accuracy have been achieved compared to the previously proposed CNN-based and Gabor-based methods.

Design/methodology/approach
The authors have implemented the new algorithm of Gabor convolution network on the hyperspectral images for classification purposes.

Findings
Implementing the new GCN has shown unexpectable results with an excellent classification accuracy.

Originality/value
To the best of the authors’ knowledge, this work is the first one that implements this approach.
Properties of self-compacting mortar made with various mineralogical sources different types of sands and fillers
Authors: Nécira Brahim , Abadou Yacine 
Published: May 2021

Purpose
By its high fluidity, great deformability and rheological stability, the self-compacting mortar (SCM) is capable of ensuring the ability to be easily implemented without vibration. However, its formulation requires a large volume of fine materials with a high dosage of cement, which is necessary to ensure adequate workability and mechanical strengths, which is necessary to allow its flow. Current environmental considerations encourage reducing the production of cement, it is essential to use additions to replace the cement, because of their great availability and their moderate price. On another side, their use contributes to an economic sort to solve the problems related to the environment.

Design/methodology/approach
The formulations and characteristics of SCM made with two types of mineralogical sources (silica and limestone) were investigated. Different materials were used separately and in binary combinations; silica river sand (SRS), limestone quarry sand (LQS), silica fillers (SF) and limestone fillers (LF). The formulation starts with the self-compacting pastes (SCPs) then the SCMs at the SRS and the LQS whose the cement is partially replaced by volume contents of SF and LF with 15%, 30% and 45%.

Findings
The results obtained prove that the incorporation of LQS instead of SRS has a negative effect on the fluidity and deformability and a positive effect on the mechanical strengths of SCM. In addition, the incorporation of the SF and LF reduces the need for water and the saturation dose of superplasticizer in the pastes. Thus, the addition of the SF and LF in specific voluminal contents (15% SF and 30% LF) in the binder can have a beneficial effect on the parameters of the workability and the mechanical strengths of SCM. These results are very interesting to aspects such as technological, economic and environmental.

Originality/value
Influence of the different type of sands and fillers in improvements the properties of SCM made from various mineralogical sources.
Building an ecologically founded disease risk prioritization framework for migratory wildlife species based on contact with livestock
Authors: Khanyari Munib , Robinson Sarah , Morgan Eric R. , Brown Tony , Singh Navinder J. , Salemgareyev Albert , Zuther Steffen , Kock Richard , Milner‐Gulland E. J. 
Published: May 2021

Abstract

Shared use of rangelands by livestock and wildlife can lead to disease transmission. To align agricultural livelihoods with wildlife conservation, a multipronged and interdisciplinary approach for disease management is needed, particularly in data‐limited situations with migratory hosts. Migratory wildlife and livestock can range over vast areas, and opportunities for disease control interventions are limited. Predictive frameworks are needed which can allow for identification of potential sites and timings of interventions.

We developed an iterative three‐step framework to assess cross‐species disease transmission risk between migrating wildlife and livestock in data‐limited circumstances and across social‐ecological scales. The framework first assesses risk of transmission for potentially important diseases for hosts in a multi‐use landscape. Following this, it uses an epidemiological risk function to represent transmission‐relevant contact patterns, using density and distribution of the host to map locations and periods of disease risk. Finally, it takes fine‐scale data on livestock management and observed wildlife–livestock interactions to provide locally relevant insights on disease risk.

We applied the framework to characterize disease transmission between livestock and saiga antelopes Saiga tatarica in Central Kazakhstan.

At step 1, we identified peste‐des‐petits‐ruminants as posing a high risk of transmission from livestock to saigas, foot‐and‐mouth disease as low risk, lumpy skin disease as unknown and pasteurellosis as uncertain risk. At step 2, we identified regions of high disease transmission risk at different times of year, indicating where disease management should be focussed. At step 3, we synthesized field surveys, government data and literature review to assess the role of livestock in the 2015 saiga mass mortality event from pasteurellosis, concluding that it was minimal.

Synthesis and applications. Our iterative framework has wide applicability in assessing and predicting disease spill‐over at management‐relevant temporal and spatial scales in areas where livestock share space with migratory species. Our case study demonstrated the value of combining ecological and social information to inform management of targeted interventions to reduce disease risk, which can be used to plan disease surveillance and vaccination programmes.
Floral complexity can help maintain plant diversity by inducing pollinator specialization
Authors: Gurevich Yael , Hadany Lilach 
Published: May 2021

Abstract

The global decline in plant biodiversity throughout recent human history has attracted broad scientific attention, as biodiversity plays a key role in promoting a productive ecosystem. Pollination is a major factor in plant survival but carries an additional cost for locally rare plant species: they are likely to receive high levels of incompatible pollen that does not contribute to reproduction and can even impair seed production. Therefore, floral traits that diminish the risk of incompatible pollen receipt may be favoured by natural selection.

We developed a theoretical framework to explore the influence of floral morphological complexity on competition for pollinator services between self‐incompatible simultaneously flowering plant species.

We show that when a rare plant species is morphologically complex, it may persist in competition with a more common species.

Synthesis. The results show that, through its influence on pollinator foraging behaviour, complex floral morphology can contribute to the maintenance of plant diversity.
