Abstract
This paper examines the enhancement in the properties of thermoplastic elastomer (TPE) reinforced by graphene nanoplates (GNPs). TPE is a blend of polypropylene (PP), natural rubber (NR) and liquid natural rubber (LNR), which is used as a compatibiliser at a percentage of volume ratio 70:10:20, respectively. Using TPE as the host matrix, TPE/GNPs nanocomposites are processed, and the mechanical, electrical and structural properties are characterised. The results extracted from the tensile and the impact tests showed that the tensile strength, Young’s modulus and the impact strength of the nanocomposites also increased as the filler loading increased until an optimum value of filler loading was reached. Based on the experimental results, GNPs strongly affected the electrical conductivity due to disruption of the GNPs percolated network. It is believed that the high aspect ratio of GNPs is a critical issue concerning the constitution of a special interface region between the GNPs and TPE matrix and the high performance of the composites.

Abstract
Purpose
This paper explores the collaborative dynamics and dimensions within a virtual multi-cultural and interdisciplinary workplace. The study focusses on the use of online communication technologies to enhance social inclusion and networking within academia.
Design/methodology/approach
This study uses an autoethnographic approach to draw on the personal experiences of a team of four scholars, including three early-career researchers and a senior scholar. Their reflections on their academic positionality and the institutional constraints reveal both the strengths and vulnerabilities of collaborating in a virtual workplace.
Findings
The findings offer insights into the complexities of navigating social dynamics, such as delegating responsibilities, organising meetings across various time zones and encouraging continuous collaboration, inclusivity and effective communication during an extensive timeline. As a result, their experiences revealed that a virtual workplace culture with similar and different attributes to a “normal” workplace emerged.
Originality/value
The paper demonstrates how to create an effective and inclusive virtual workplace by exemplifying best practices in academia and providing practical guidance for individuals and institutions based on honest, co-produced autoethnographic reflections of the authors’ lived experiences.

Abstract
Purpose
The study aims to explore and explain the affordances and constraints of two-mode virtual collaboration as experienced by a newly forming international research team.
Design/methodology/approach
This is self-reflective and action-oriented research on the affordances and constraints of two-mode virtual collaboration. In the spirit of professional development, the authors (nine researchers at different career stages and from various counties) engaged in a joint endeavour to evaluate the affordances and constraints of virtual collaborations in light of the recent literature while also researching the authors' own virtual collaboration during this evaluative task (mid-January–April 2021). The authors used two modes: synchronous (Zoom) and asynchronous (emails) to communicate on the literature exploration and recorded reactions and emotional responses towards existing affordances and constraints through a collective journal.
Findings
The results suggest both affordances in terms of communication being negotiable and evolving and constraints, particularly in forming new relations given tools that may not be equally accessible to all. Journaling during collaborations could be a valuable tool, especially for virtual collective work, because it can be used to structure the team supported negotiation and discussion processes, especially often hidden processes. It is evident that the role of a leader can contribute to an alignment in the assumptions and experiences of trust and consequently foster greater mutual understanding of the circumstances for productive team collaborations.
Originality/value
The findings of this study can inform academics and practitioners on how to create and facilitate better opportunities for collaboration in virtual teams as a rapidly emerging form of technology-supported working.

The paper aims to develop and validate an instrument to measure users’ perceptions of online personalized advertising.
Abstract
Purpose
The paper aims to develop and validate an instrument to measure users’ perceptions of online personalized advertising.
Design/methodology/approach
First, we identified 12 different aspects of online personalized advertisement and formulated candidate items through a literature review. A card sorting study and expert review were conducted to generate the initial scale items. We then conducted one survey (n = 308) to create a reliable measurement instrument and another (n = 296) to validate the instrument. Finally, we tested how the dimensions of the OPAD-Perception Framework can be used to differentiate between different levels of ad sensitivity, control/no control over the ad personalization process, and different levels of granularity of ad explanation.
Findings
The resulting OPAD-Perception Framework contains 49 Likert-formatted questions measuring ten distinct dimensions of online personalized advertising: reliability, usefulness, transparency, interactivity, targeting accuracy, accountability, creepiness, willingness to rely on, self-actualization, and persuasion.
Originality/value
The OPAD-Perception Framework can serve as a powerful tool to measure users’ attitudes toward online personalized advertising. This will enable advertisers and social media platforms to better support users’ privacy expectations and provide user-friendly interfaces for controlling the ad personalization process.

Abstract
Purpose
The study is done to investigate the factors that affect the intention of higher education students towards online education. The research also focuses on the importance of students' stability and students' resilience on perceived usefulness and perceived easiness of use that frame the attitude towards the intention to use online education.
Design/methodology/approach
Online survey method is employed using Google form link with a sample of 686 students of higher education. Excluding the outliers (univariate and multivariate), the final sample size (N = 679) considers the empirical results of the study. Partial least square structural equation modelling (PLS-SEM) is applied to unearth the relationship in the proposed research model of the study.
Findings
The empirical results indicate that perceived usefulness and perceived easiness of use have a direct impact on students' intention to use online education platform. Moreover, perceived usefulness and perceived easiness of use also have a positive influence on the students' attitude, which has a strong influence on students' intention to use online mode of education system. Also, students' stability and students' resilience have mixed impact on the level of perceived usefulness and perceived easiness of use that are the most useful determinants of attitude towards the intention to use online education.
Research limitations/implications
The study counts on the technology acceptance model (TAM) where constructs like behavioural controllability, past exposure and perceived accordance are not considered for measuring the intention of students in adapting to online education.
Originality/value
This paper employs the extended model of technology acceptance with additional determinants, namely, students' stability and students' resilience, to investigate the intention to use the online form of education as an alternative to the offline mode.
