The authors investigate how COVID-19 has influenced the amount, type or topics of abuse that UK politicians receive when engaging with the public.

This work covers the first year of COVID-19 in the UK, from March 2020 to March 2021 and analyses Twitter abuse in replies to UK MPs. The authors collected and analysed 17.9 million reply tweets to the MPs. The authors present overall abuse levels during different key moments of the pandemic, analysing reactions to MPs by gender and the relationship between online abuse and topics such as Brexit, the government’s COVID-19 response and policies, and social issues.

The authors have found that abuse levels towards UK MPs were at an all-time high in December 2020. Women (particularly those from non-White backgrounds) receive unusual amounts of abuse, targeting their credibility and capacity to do their jobs. Similar to other large events like general elections and Brexit, COVID-19 has elevated abuse levels, at least temporarily.

Previous studies analysed abuse levels towards MPs in the run-up to the 2017 and 2019 UK General Elections and during the first four months of the COVID-19 pandemic in the UK. The authors compare previous findings with those of the first year of COVID-19, as the pandemic persisted, and Brexit was forthcoming. This research not only contributes to the longitudinal comparison of abuse trends against UK politicians but also presents new findings, corroborates, further clarifies and raises questions about the previous findings.

The purpose of this study is to extend the Fraud Diamond Theory to celebrity Special Purpose Acquisition Companies (SPACs) and investigate their post-Initial Public Offering (IPO) stock market performance.

After obtaining a sample of celebrity SPACs from the Spacresearch.com database, fraud risk characteristics were obtained from Lexis Nexus searches. Buy and hold abnormal returns were calculated for celebrity SPACs versus a small-cap equity benchmark for time intervals after IPO, and multiple regression analysis was performed to examine the relationship between fraud risk features and post-IPO returns.

Celebrity SPACs exhibit Fraud Diamond characteristics and significantly underperform a small-cap stock portfolio on a risk-adjusted basis after IPO.

This study only examines celebrity SPACs that conducted IPOs on the NYSE and NASDAQ/AMEX and does not include those that are traded on the Over the Counter Bulletin Board (OTCBB).

Celebrity endorsement of SPAC vehicles attracts investors who may not be properly informed regarding the risk characteristics of SPACs. Accordingly, investors should be warned that celebrity SPACs underperform a small-cap equity portfolio and exhibit significant elements of fraud risk.

The use of celebrity endorsement as a marketing device to attract investment in SPACs has regulatory implications.

To the best of the authors’ knowledge, this paper is the first to examine the fraud risk characteristics and post-IPO performance of celebrity SPACs.

The paper aims to explore the role of union strategic influence on the adoption of High Performance Work Systems (HPWS) in organisations and examines how the effects of job security and then in turn the industrial relations climate, mediate this relationship in a serial manner.

The research analyses an original quantitative survey of union negotiators and representatives in 382 workplaces in England. The analysis employs structural equation modelling techniques to examine the relationships between union influence, job security, industrial relations climate and HPWS.

Union strategic influence has a positive effect on the take up of HPWS in unionised workplaces. Job security and the industrial relations climate demonstrate a serial mediation effect between union strategic influence and the take up of HPWS: union strategic influence has a positive effect on job security, which in turn positively impacts the industrial relations climate, thereby increasing the likelihood of the adoption of HPWS. The findings for the industrial relations climate are particularly strong.

Findings suggest that organisations will benefit from focussing on the development of positive industrial relations, where unions have genuine strategic influence, because this maximises the likelihood that HPWS can be adopted and sustained.

The paper provides a novel focus on the take up of HPWS within unionised workplaces. It focusses on the role of union strategic influence and the mediating effects of job security and the industrial relations climate, which are contextual factors that have been underexplored in the HPWS literature to date.

The purpose of this paper is to examine the effects of performance management (PM) practices on in-bound open innovation (OI) and out-bound OI. To do this, the authors examine the organizational effectiveness as well as the non-financial and financial performance of Brazilian startups that have had recent OI relationships with larger companies.

Using data collected from 103 Brazilian startups, the hypotheses were tested via partial least squares–structural equation modeling (PLS-SEM). An additional analysis was performed using fuzzy-set qualitative comparative analysis (fsQCA).

The findings show that PM practices orchestrate in-bound OI and out-bound OI; however, only in-bound OI promotes organizational effectiveness in Brazilian startups. Organizational effectiveness results in good non-financial performance, which in turn improves financial performance. PM practices have an indirect effect on financial performance from the serial mediation of in-bound OI, organizational effectiveness and non-financial performance. Moreover, several combinations of conditions lead to high levels of organizational effectiveness, non-financial performance and financial performance.

This study provides new evidence and insights from an emerging market on the antecedents and consequences of startups' OI adoption.

The purpose of this study is to examine the effect of extrinsic aspects of the technology acceptance model, namely, information quality, functionality, accessibility, user interface design, system quality, functionality, facilitating conditions and computer playfulness as well as intrinsic aspects, namely, perceived self-efficacy, enjoyment and learning goals. orientation on perceived usefulness and perceived ease of use in the context of the learning management system (LMS) as a system to support employee learning and development. This study also analyzes the effect of perceived ease of use on perceived usefulness and analyzes the effect of these two variables on the intention to adopt a LMS. This study included 3,205 respondents who are employees of banking companies in Indonesia and who used the LMS for their learning and self-development needs during the COVID-19 pandemic.

This research is a quantitative study that uses online surveys to collect data and partial least squares statistical tools to analyze survey data.

The results showed that accessibility alone had no effect on perceived usefulness and perceived ease of use, while enjoyment had no effect on the intention to use LMS and perceived ease of use and functionality had no effect on the intention to use LMS.

This research focuses on the concept of technology acceptance with extrinsic and intrinsic aspects. This research context involves employees working in the banking sector with the adoption of the LMS.

LMS in banking companies can be optimized by providing online training and reducing the operational costs of employee training. By using LMS, companies can offer online courses to employees and track progress in distance learning, become a learning choice and information dissemination during the pandemic and also support future business continuity.

This study focuses on testing the technology adoption model on LMSs in the banking sector by adding extrinsic aspects, namely, system quality, facilitating conditioning, computer playfulness and user interface design, and combining intrinsic aspects, namely, perceived self-efficacy, enjoyment and learning goal orientation.

When a company practices greenwashing, it violates consumers' expectations by deliberately deceiving them about their environmental practices or the benefits of their products/services. This study investigated the effects of greenwashing on corporate reputation and brand hate. Furthermore, this study explored the mediating effects of perceived environmental performance and green perceived risk.

A survey design using cross-sectional primary data from 420 Portuguese consumers who identified and recognized brands engaged in greenwashing was employed. The proposed hypotheses were tested using structural equation modeling techniques.

This study's findings show that consumer perceptions of greenwashing may damage brands. The results show that greenwashing has a negative effect on corporate reputation through perceived environmental performance and green perceived risk. Additionally, greenwashing has a positive direct effect on brand hate and a negative effect on green perceived risk. Therefore, reducing greenwashing practices can improve consumers' perceptions of corporate environmental performance, buffer green perceived risk, and ultimately enhance corporate reputation. This can lead to positive relationships with customers.

Based on signaling and expectancy violation theories, this study develops a new framework highlighting the detrimental effects of greenwashing on brands. The combination of these theories provides the right framework to understand how greenwashing may lead to extreme feelings like brand hate and negative perceptions of corporate reputation, thus advancing the current research that lacks studies on the association between these constructs.
