Relying on the effort-recovery model, this study aimed to test how and when a good night’s sleep increases in daily physical health. The authors hypothesized that when individuals have a good night’s sleep, it helps them to recover their self-regulatory resources, and, in turn, these cognitive resources improve their physical health experienced at work. Furthermore, the authors argue that this will be different depending on the individuals’ levels of neuroticism; that is, the indirect relationship between sleep duration and physical health through self-regulatory resources will be stronger for individuals who score lower on neuroticism, and in contrast, the relationship will be buffered for those who score higher on neuroticism.

To test the hypothesized model, the authors conducted a three-wave longitudinal study with working adults (N = 262). The authors used multilevel modelling to test if neuroticism moderated the indirect relationship between sleep duration and physical health through self-regulatory resources, at both between and within-person levels.

The multilevel results showed that a good night’s sleep recovered self-regulatory resources needed to promote physical health; however, this indirect relationship was buffered for those who scored higher on neuroticism (versus lower levels of neuroticism).

Hence, the role of neuroticism as a potentially harming condition for employees’ physical health is pointed out.

The findings highlight the relevance of sleep as a recovery activity for both cognitive and physical resources experienced during the working day. However, this appears to be attenuated for employees with higher levels of neuroticism.

This study aims to explore the role of team personality and leader’s humor style on the use of humor in group communication and the extent to which group humor mediates the association between team personality on the one hand, psychological safety, collective emotional intelligence and group satisfaction on the other hand.

The authors used a survey to collect data from 304 employees nested in 83 groups working in organizations from various sectors in Romania.

The study results show that extraversion is positively associated with group affiliative humor, while neuroticism has a positive association with group aggressive humor. The leader’s affiliative humor style had a significant positive effect on group affiliative humor, while the effect of leader’s aggressive humor style on the use of aggressive humor in groups was not significant. Furthermore, the authors examined the mediation role of group humor in the relationship between team personality and team emergent states and satisfaction. The authors found that group aggressive humor mediates the association between neuroticism and group emotional intelligence, psychological safety and satisfaction, while affiliative humor mediates the association between extraversion and emotional intelligence and team satisfaction.

The study reports one of the first attempts to explore the multilevel interplay of team personality and humor in groups as they relate to emergent states.

This study aims to examine the relationship between the personality dimensions of consumers and celebrities; the effect of celebrity personality on attitude towards the celebrity; and the effect of attitude towards the celebrity on purchase intention.

Data were gathered from 400 respondents in the North of England to explore the connections between five consumer personality dimensions (agreeableness, extroversion, openness, conscientiousness and neuroticism) and nine celebrity personality dimensions (neuroticism, extroversion, openness, agreeableness, conscientiousness, sincerity, excitement, stylishness and positivity) and were analysed using structural equation modelling.

The findings suggested that some dimensions of consumer personality, i.e. conscientiousness, extroversion and openness, were significantly related to all the celebrity personality dimensions. Moreover, all the celebrity personality dimensions had a significant effect on consumers’ attitude towards the celebrity; however, only neuroticism, extroversion, openness, sincerity and positivity significantly affected purchase intention. Finally, attitude towards the celebrity had a significant effect on purchase intention.

The study introduces a celebrity personality scale and explores a topic that has not previously been researched.

This longitudinal study aims at assessing the impact of openness to experience and neuroticism on affective states experienced by the academics from the Malaysian public universities during the first strict COVID-19 lockdown in 2020.

The author collected data for openness to experience and neuroticism at the beginning of the lockdown, and for positive and negative affect, when the lockdown ended. The author used the efficient partial least squares structural equation modeling (PLSe2-SEM) methodology to fit the model to the screened data (N = 291).

The results showed that openness to experience had a negative effect on negative affect and a positive effect on positive affect. The author also observed that neuroticism had a positive effect on negative affect and a negative effect on positive affect. These findings provided support for the proposition of the impact of personality traits on affective states amidst the COVID-19 pandemic in academic settings.

The study shows that careful assessment of lecturers' personality traits should be considered during the process of selection and recruitment since these factors, theoretically and empirically, trigger affective states which, in turn, lead to behaviors and attitudes.

This is the first study on examining the impact of academics' personality traits on their affective states. Also, it is amongst the few longitudinal studies on evaluating personality traits during the COVID-19 pandemic. As a methodological novelty, the author used the PLSe2 methodology to test the model and compared the results with maximum likelihood (ML) results.

This study investigates how personality traits influence individuals’ intention to become community group buying (CGB) leaders.

Data include 517 valid questionnaires that are employed to examine the research model and test the hypotheses using partial least squares structural equation modeling.

This study reveals that among the Big Five personality traits, extroversion and neuroticism have more impact on the perceived ease of use and usefulness of social media, and individuals with high levels of these traits are more likely to become CGB leaders. Perceived ease of use only mediates the relationship between agreeableness and CGB leader intention, whereas perceived usefulness mediates the relationships between conscientiousness and CGB leader intention and neuroticism and CGB leader intention.

This study can serve as a catalyst for advancing the exploration of how personality traits and social media affect the intention of being CGB leaders. In addition, the study investigates the mediating effect of social media technology acceptance obtaining valuable insights into how social media affects individuals’ intention to become CGB leaders, expanding the research in this field.

As social media has become an ingrained aspect of our lives—including our political relationships with other citizens and the state—various governments have warned public servants that being politically active online might threaten the reputed impartiality of themselves and the public service. This study examines whether public servants are less likely to be politically active on social media than other citizens, and seeks to understand public servants’ varying disposition to be politically active online by investigating the role of employees’ underlying Big 5 personality traits.

Multivariate regression, along with marginal effects and predicted probabilities, are used to investigate public servants’ online political activity with survey data from Canada, a country where impartiality is a core public service value, and where governments, public service commissions and even public sector unions have voiced cautious messages about the threat online political activity presents to the reputed impartiality of public servants, and the public service at large.

Analysis of the direct effects of being a public servant and each Big 5 personality trait finds that being a public servant significantly, and substantively, reduces the probability of engaging in online political activity, meanwhile, Extraversion and Conscientiousness have consistent, significant and substantive relationships with being politically active online. Subsequent analysis investigating the dynamic between the Big 5 and being a public servant, uncovers a more complex story. Among public servants, Openness and Neuroticism, rather than Extraversion and Conscientiousness, are associated with significant and substantive changes in the probability of engaging in some online politically activities. This is consistent with research investigating the relationship between the Big 5 and risk aversion, given that public servants in Canada work in an environment with a highly cautious discourse portraying social media as a serious risk to impartiality.

The findings also speak to best practices for public service human resource managers by shedding light how public servants’ behavior can be better understood and managed by paying attention to their underlying personality traits.

This study moves beyond analyzing trends between public and private sector employees, to instead examine public servants’ online political activity. This study offers theoretical and empirical insight into how public servants’ disposition to be politically active online is, in part, influenced by their underlying Big 5 personality traits, specifically, Neuroticism and Openness.

On the basis of affective events theory, this study aims to examine the connection between work-related events (i.e. supervisor role ambiguity and role conflicts) and abusive supervision via emotion (i.e. supervisor frustration). This study also examines the moderating role of supervisor personality traits (i.e. neuroticism and conscientiousness).

This study collected lagged and multisource field data (472 subordinates and supervisors dyads) from the service organizations.

The data collected supported majority of this study’s hypothesized relationships regarding determinants of abusive supervision.

This study underlines what triggers supervisor abuse. This study also enables organizations with the intervention opportunity to reduce the effects of supervisor role ambiguity, role conflict, negative emotions and personality on triggering abusive supervision.

Prior research on abusive supervision has extensively focused on its outcomes, leaving a noteworthy research gap about what triggers abusive supervision. To fill this important gap in leadership literature, this study proposed and tested a research model of determinants of supervisor abuse. Thus, this study contributes to leadership and abusive supervision research. Implications and future research directions are discussed.

Financial professionals are increasingly important in the Indian financial system. Our study examines the association between the Big Five personality traits and Indian financial professionals' behavioral biases when making investment decisions.

After testing our questionnaire's reliability and validity, we used it to obtain the sample responses. We used multiple regression analysis and other statistical tools to identify the relationships between the Big Five personality traits and behavioral biases.

Our findings reveal a high level of extraversion and conscientiousness, a moderate level of agreeableness and openness and a low neuroticism level among financial professionals. The results show a significant association between neuroticism, extraversion, openness and all behavioral biases except anchoring bias. The neuroticism trait has a statistically significant relationship with all behavioral biases examined, whereas agreeableness and conscientiousness traits lack a significant association with behavioral biases. The openness trait is associated with many emotional biases and cognitive heuristics, while the extraversion trait has a significantly positive relationship with availability bias.

Future researchers could analyze primary (survey) and secondary investor data from brokerage houses. Using a larger sample could provide more generalizable findings. Researchers could also consider other aspects of investment decision-making using various asset classes. Understanding financial professionals' personality traits and behavioral biases could help them develop strategies to suit client needs.

This study provides the first comprehensive examination of the association between personality traits and behavioral biases of Indian financial professionals.

Online open innovation platforms provide opportunities for product users to participate in the innovation process and contribute their ideas to the platform. Nonetheless, they also present a significant challenge for platform managers, who select high-quality innovations from a massive collection of information with diverse quality.

In this study, the authors employed a machine learning method to automatically collect a real dataset of 2,276 innovations and 30,004 detailed comments from the online platform of IdeaExchange and then conducted empirical experiments to verify the study hypothesis.

Results show that extraversion, conscientiousness and openness to experience positively and directly influenced the quality of their innovation. Furthermore, an individual's social network position mediated among extraversion, neuroticism, conscientiousness and openness to experience and the quality of an innovation.

Results showed that extraversion, conscientiousness and openness to experience positively and directly influenced the quality of their innovation. Furthermore, an individual's social network position mediated among extraversion, neuroticism, conscientiousness, openness to experience and the quality of innovations.

This study combined the Big Five personality traits theory and social network theory to examine the association between user intrinsic personality traits, social network position and the quality of their innovative ideas in the context of online innovation platforms. Additionally, the findings provide new insights for platform managers on how to select high-quality innovation information by considering user personality traits and their social network position.

The study aims to examine the relationship between personality traits and investor risk behavior of the individuals trading in stock markets. Furthermore, this study establishes the association of financial literacy on the relationship between personality traits and investor risk behavior.

The authors analyze cross-sectional survey method data by using moderated multiple regression analysis, a standard method of determining the moderation effect. PROCESS Model method has been used in this study to check the robustness of the results.

The findings reveal that personality traits significantly influence investor risk behavior and financial literacy modifies the fundamental relationships between personality traits and investor risk behavior. The findings also conclude that behavioral impact was predetermined by individuals' genetic traits and is influenced by financial literacy.

The current study provides valuable insights for investors and adamant grounds for future research. The two-fold role of individuals' personalities in case of gains and losses can be of interest to the researchers in future.

Investors currently facing the complex financial choices which are far beyond the day-to-day financial advice. This study guides rational investment behavior for portfolio managers and investors for advanced investment options.

Most of the prior literature is based on developed markets, whereas the current study focuses on less literate society (i.e. Pakistan) to protect the investors from scams and fraud. The current study supports the vital role of investors in the socio-economic development of emerging markets.

The authors believe this study expands the boundaries of personality theories, especially in the context of risk behavior and financial literacy. The study also contributes to advancing the personality theory trimmed with financial literacy and investor behavior while making important theoretical inroads for future research.
