A common understanding of what events to regard as production disturbances (PD) are essential for effective handling of PDs. Therefore, the purpose of this paper is to answer the two questions: how are individuals with production or maintenance management positions in industry classifying different PD factors? Which factors are being measured and registered as PDs in the companies monitoring systems?

A longitudinal approach using a repeated cross-sectional survey design was adopted. Empirical data were collected from 80 companies in 2001 using a paper-based questionnaire, and from 71 companies in 2014 using a web-based questionnaire.

A diverging view of 21 proposed PD factors is found between respondents in manufacturing industry, and there is also a lack of correspondence with existing literature. In particular, planned events are not classified and registered to the same extent as downtime losses. Moreover, the respondents are often prone to classify factors as PDs compared to what is actually registered. This diverging view has been consistent for over a decade, and hinders companies to develop systematic and effective strategies for handling of PDs.

There has been no in-depth investigation, especially not from a longitudinal perspective, of the personal interpretation of PDs from people who play a central role in achieving high reliability of production systems.

Lack of acceptance of insects as food is considered a barrier against societal adoption of the potentially valuable contribution of insects to human foods. An underlying barrier may be that insects are lumped together as one group, while consumers typically try specific insects. The purpose of this paper is to investigate the ways in which Dutch consumers, with and without insect tasting experience, are more or less willing to eat different insects.

In a quasi-experimental study (n=140), the participants with and without prior experience in eating insects were asked to give their willingness to eat a range of insects, and their attitudes and disgust towards eating insects.

Insects promoted in the market were more preferred than the less marketed insects, and a subgroup of preferred insects for participants with experience in eating insects was formed.

Although well-known insects were more preferred, general willingness to eat remained low for all participants. The results indicate that in future research on insects as food the specific insects used should be taken into account.

Continued promotion of specific, carefully targeted, insects may not lead to short-term uptake of insects as food, but may contribute to willingness to eat insects as human food in the long term.

The paper shows substantial differences between consumers who have and who have not previously tasted insects, with higher acceptance of people with experience in tasting insects for the specific insects that are frequently promoted beyond their generally more positive attitude towards eating insects.

In response to growing concerns over the negative consequences of Internet addiction on adolescents’ mental health, coupled with conflicting results in this literature stream, this meta-analysis sought to (1) examine the association between Internet addiction and depressive symptoms in adolescents, (2) examine the moderating role of Internet freedom across countries, and (3) examine the mediating role of excessive daytime sleepiness.

In total, 52 studies were analyzed using robust variance estimation and meta-analytic structural equation modeling.

There was a significant and moderate association between Internet addiction and depressive symptoms. Furthermore, Internet freedom did not explain heterogeneity in this literature stream before and after controlling for study quality and the percentage of female participants. In support of the displacement hypothesis, this study found that Internet addiction contributes to depressive symptoms through excessive daytime sleepiness (proportion mediated = 17.48%). As the evidence suggests, excessive daytime sleepiness displaces a host of activities beneficial for maintaining mental health. The results were subjected to a battery of robustness checks and the conclusions remain unchanged.

The results underscore the negative consequences of Internet addiction in adolescents. Addressing this issue would involve interventions that promote sleep hygiene and greater offline engagement with peers to alleviate depressive symptoms.

This study utilizes robust meta-analytic techniques to provide the most comprehensive examination of the association between Internet addiction and depressive symptoms in adolescents. The implications intersect with the shared interests of social scientists, health practitioners, and policy makers.

The purpose of the present study was to investigate the impact of sport fans' team identification on their emotional experiences (i.e. vitality and game satisfaction) using two-wave data in a specific sport event during the declaration of the emergency statement in Japan. The study also aims to test the moderating effects of risk perceptions about COVID-19 and the game outcome on the relationship between team identification and vitality/game satisfaction.

The present research was conducted in the context of a sport event in Tokyo (the Japanese Rugby Top League 2020–2021 Season Playoff Tournament Final) during the declaration of the emergency statement period in Japan. The data were collected through a two-wave design (before and after the game) from the spectators of the event.

Team identification significantly predicted higher vitality after the game but not game satisfaction. Additionally, the moderation test found that sport fans with high social risk perception about the COVID-19 showed a positive relationship between team identification and vitality but not for the fans with low social risk perception.

The present results suggest that sport events can be advertised for sport fans as a tool to increase physical and psychological energy in their daily lives during the pandemic.

The present study demonstrated that team identification predicted greater vitality after the spectatorship during the COVID-19 outbreak. In particular, higher social risk perception was a significant catalyst to improve vitality after the game.

Metaverse is a virtual application spawned by digital technology that is becoming increasingly relevant to our lives. However, for the opportunities created and challenges posed by the metaverse, its important elements and future evolution trend remain largely unknown. Thus, this paper aims to understand the current status of metaverse research and its future research directions.

Based on the analysis of the literature data on the metaverse both in English and Chinese using Latent Dirichlet allocation (LDA) topic modeling and bibliometrics, this study discussed the related research and development trend of the metaverse. The authors first defined the concept of the metaverse and analyzed 1,378 English articles from seven publishers and 590 Chinese articles from the CNKI database. Following that, the authors summarized three important themes from the current studies: virtual world, metaverse technologies and metaverse applications. Finally, a framework of future directions on metaverse research was proposed.

The review found that during the rapid development of the metaverse, opportunities and challenges coexisted. In the virtual world, metaverse technologies drive the implementation of application scenarios, and in turn, applications promote the improvement of technologies. The interrelationship between technology and application lays the foundation for the development of the metaverse. Future metaverse research will generate different research directions.

This review provides a valuable, systematic perspective for individuals who want to understand the metaverse. The conceptual framework on metaverse research proposed in this paper offers a comparison of literature analysis from domestic and international perspectives and brings new insights into the development of the metaverse.

This paper describes and discusses company spin-ins and spin-outs as a means to understand company growth in a dynamic context. The following question is asked: How can growth be understood in spin-ins and spin-outs of innovative firms? The paper suggests return on capabilities as a measure to understand growth in an open innovation context.

The empirical part of the paper consists of a single case study. Data was captured through interviews and secondary data sources.

The paper points to that resources alone do not explain strategic decisions by a company and how spin-ins and spin-outs result from the need for capabilities, changes in business foci and temporary solutions to deal with overcapacities or lack of alternatives.

The paper contributes to research by discussing contemporary issues in strategy and innovation and relating them to the resource-based view and the growth of the firm. Spin-outs, and acquisitions and divestitures as interlinked events have rarely been focused on in the literature, while they remain frequent phenomena in practice.

The COVID-19 pandemic has affected women in unique gender-specific ways, particularly their traditional status as home managers. This study aims to draw on the role theory to examine the impact of the COVID-19 pandemic on women's work–family balance during the lockdown.

The current COVID-19 pandemic, which has altered the ways in which we live and work, requires specific methodological tools to be understood. The authors, therefore, opted for an interpretive–constructivist and constructivist–phenomenologist approach. The dataset, thus, comprises of semi-structured interviews with 26 working women in the UK.

The findings illustrate how the COVID-19 lockdown has intensified British women's domestic workload and has, thus, caused unbridled role conflict, which has further been exacerbated by structural and interactional roles undertaken by women, especially during the lockdown. Remote working has contributed to women's role congestion and role conflict and poses severe challenges to role differentiation. Furthermore, we found that the lockdown has facilitated the rediscovery of family values and closeness, which is connected to the decline in juvenile delinquency and low crime rate that has resulted from the lockdown.

Through the lens of the role theory, this study concludes that the cohabitation of work and family duties within the domestic space undermines the ability to achieve work–family balance and role differentiation due to the occurrence of inter-role conflicts. This study enriches our understanding of the effect of remote working on female employees' work–family balance during the unprecedented COVID-19 pandemic lockdown.

This paper investigates the ways managing directors (MDs) in small and medium-sized enterprises (SMEs) involve employees in strategic conversations. The paper examines how managers interact with employees in strategic conversations, and why the managers do so (or do not), to generate empirically grounded knowledge about the nature of internal openness in SMEs.

This study employs a general inductive approach and is based on in-depth interviews with 60 Swedish MDs with development and growth ambitions.

The paper develops a model of employee involvement in strategic conversations based on the nature and intensity of the MD–employee interaction. A key finding is that SMEs exhibit wide variation in terms of employee involvement, from virtually no employee involvement to, in some cases, far-reaching company democracy. The reasons for this variation are complex, but personal preferences and company size are shown to have an impact, as does, to some degree, ownership structure. In contrast to existing research, the limitations and drawbacks of involving employees in strategic conversations are outlined.

The study provides important insight into MDs' views and practices of internal openness in strategic conversations in SMEs. A model of employee involvement in strategic processes is outlined, and potential limitations of internal openness are highlighted.

The starting point for the considerations the authors make in this paper are the special features of family businesses in the area of management discussed in the literature. It has been established here that family businesses sometimes choose different organizational setups than nonfamily businesses. This has not yet been investigated for cybersecurity. In the context of cybersecurity, there has been little theoretical or empirical work addressing the question of whether the qualitative characteristics of family businesses have an impact on the understanding of cybersecurity and the organization of cyber risk defense in the companies. Based on theoretically founded hypotheses, a quantitative empirical study was conducted in German companies.

The article is based on a quantitative-empirical survey of 184 companies, the results of which were analyzed using statistical-empirical methods.

The article asked – based on the subjective perception of cybersecurity and cyber risks – to what extent family businesses are sensitized to the topic and what conclusions they draw from it. An interesting tension emerges: family businesses see their employees more as a security risk, but do less than nonfamily businesses in terms of both training and organizational establishment. Whether this is due to a lack of technical or managerial expertise, or whether family businesses simply think they can prevent cybersecurity with less formal methods such as trust, is open to conjecture, but cannot be demonstrated with the research approach taken here. Qualitative follow-up studies are needed here.

This paper represents the first quantitative survey on cybersecurity with a specific focus on family businesses. It shows tension between awareness, especially of risks emanating from employees, and organizational routines that have not been implemented or established.

Increasing incidents of privacy invasion on social networking sites (SNS) are intensifying the concerns among stakeholders about the misuse of personal data. However, there seems to be limited research on exploring the impact of specific privacy concerns on users’ intention to engage in various privacy protection behaviors. This study aims to examine the role of social privacy concerns, institutional privacy concerns and privacy self-efficacy as antecedents of privacy protection–related control activities intention among young adults active on SNS.

Data collected from 284 young adults active on SNS was analyzed through partial least squares structural equation modeling using Smart PLS.

The results indicate that institutional privacy concerns, social privacy concerns and privacy self-efficacy positively influence the control activities intention of SNS users. The extent of privacy self-efficacy and privacy protection-related control activities intention differs among users based on gender.

This study is limited to a population of young adults in the age group of 18–25 years.

The findings of this study form the basis for specific recommendations addressing the different types of privacy concerns experienced by social media users, promoting responsible privacy control behaviors on online platforms and discouraging the possible misuse of information by third parties.

This study validates a theoretical framework that can contribute to future investigations concerning the use of SNS. The study findings form the basis for a set of practical recommendations for policymakers, SNS platforms and users.
