In fire resistance tests (FRTs) of building materials, a crucial criterion to pass the test procedure is to avoid the leakage of the hot flue gases caused by gaps and cracks occurring due to the thermal exposure. The present study's aim is to calculate the deformation of a steel door, which is embedded within a wall made of bricks, and qualitatively determine the flue gas leakage.

A computational fluid dynamics/finite element method (CFD/FEM) coupling was introduced representing an intermediate approach between a one-way and a full two-way coupling methodology, leading to a simplified two-way coupling (STWC). In contrast to a full two way-coupling, the heat transfer through the steel door was simulated based on a one-way approach. Subsequently, the predicted temperatures at the door from the one-way simulation were used in the following CFD/FEM simulation, where the fluid flow inside and outside the furnace as well as the deformation of the door were calculated simultaneously.

The simulation showed large gaps and flue gas leakage above the door lock and at the upper edge of the door, which was in close accordance to the experiment. Furthermore, it was found that STWC predicted similar deformations compared to the one-way coupling.

Since two-way coupling approaches for fluid/structure interaction in fire research are computationally demanding, the number of studies is low. Only a few are dealing with the flue gas exit from rooms due to destruction of solid components. Thus, the present study is the first two-way approach dealing with flue gas leakage due to gap formation.

This chapter seeks to investigate the role of student emotional intelligence (EI) in countering in-class cyberloafing behaviour by students, by exploring the mediating role of boredom proneness through a quantitative approach. A sample of 163 postgraduate university students in India was selected. The authors assessed the mediation model using PROCESS macro. The authors found that students who are more aware of their emotions are better equipped to handle internal and external distractions and work towards a desired goal or outcome and therefore are less likely to experience boredom. Results from this study revealed a significant direct and indirect negative relationship between students’ EI and cyberloafing behaviour. This chapter contributes to the body of literature by highlighting the positive effects of EI as an important antidote to student cyberloafing behaviour. On the practical front, the findings of this study can be used by academicians who are charged with the responsibility of understanding and enhancing student learning by diminishing cyberloafing behaviour among them. The proposed framework could provide a foundation for countering cyberloafing behaviour in educational settings.

The purpose of this study is to investigate the impact of the age diversity of the top management team (TMT) on firm performance and on the managerial ability of the TMT. Furthermore, this study investigates how the relationship between age diversity and firm performance is mediated by managerial ability and the contextual nature of the relationship.

This is an empirical study which uses regression analyses and mediation analyses to evaluate the hypotheses.

The authors observe a negative relationship between age diversity and firm performance and also between age diversity and managerial ability of the TMT. Further, the authors find that that the negative relationship between age diversity and firm performance is mediated by managerial ability. The authors also find that the relation between performance and age diversity is context specific – the negative relationship between age diversity and firm performance is ameliorated during times of financial crisis.

In an environment where diversity is beginning to be valued, insights into the impact of different types of diversity on performance become important. Age diversity is a critical component of diversity. Therefore, insights into the impact of age diversity on performance will be of interest to managers, academics and even regulators.

To the best of the authors’ knowledge, this study is the first to evaluate the impact of age diversity on the market perception of firm performance of US firms using a large, comprehensive, multi-year data set. Furthermore, this is the only study to evaluate the impact of age diversity on managerial ability and show the mediating effect of managerial ability on the relationship between age diversity and firm performance.

This study investigates the validity of Ferreira et al.’s (2020) Organizational Bullshit Perception Scale by examining its distinctiveness from similar constructs (perceptions of organizational politics, organizational cynicism, procedural justice) and its predictive validity through its relations with important organizational attitudes (organizational identification) and behaviors (counterproductive work behavior and organizational citizenship behavior). This study also examines the moderating effects of honesty–humility on the relations between organizational bullshit perception and the outcomes of counterproductive work behavior, organizational citizenship behavior and organizational identification. Finally, this study examines the incremental validity of organizational bullshit perception in predicting counterproductive work behavior, organizational citizenship behavior and organizational identification above and beyond similar constructs in an exploratory fashion.

Survey data were collected from a sample of working adults online via Amazon’s Mechanical Turk platform across two waves (final N = 323 for wave 1 and 174 for wave 2), one month apart.

The results indicate that organizational bullshit perception, as measured by Ferreira et al.’s (2020) scale, represents a distinct construct that has statistically significant relations with counterproductive work behavior, organizational citizenship behavior and organizational identification, even after controlling for procedural justice, organizational cynicism and perceptions of organizational politics. The results, however, showed no support for honesty–humility as a moderator.

These findings suggest that organizations can benefit from assessing and working to alleviate their employees’ perceptions of organizational bullshit. This construct predicts behaviors and attitudes important for organizational functioning.

This study adds to Ferreira et al.’s (2020) original work by demonstrating organizational bullshit perception’s distinctiveness from existing constructs in the literature and its implications for organizations and their employees.

The purpose of this paper is to study whether the consumer’s perceptual processing style impacts consumer preference. Specifically, whether consumers with local perceptual processing style in emerging Asian countries are more likely to perceive that Asian skincare brands are suitable for them, compared with emerging Asian consumers with global perceptual processing.

An experiment was conducted with 249 Asian female respondents in an emerging Asian market. The Navon letter – a hierarchical letter – is used to classify the respondents’ perceptual processing style. The Navon stimulus used is a big letter H made up of small letter Ls. Those who saw letter H (L) at first glance were classified as consumers with global (local) perceptual processing style. ANCOVA was used to analyze the main effect of global/local perceptual processing style on product preference, as well as to test the moderating effect of age.

The results suggest that consumers with local perceptual processing style are significantly more likely to perceive that Asian brands are suitable for them, compared with respondents with global perceptual processing style. Additionally, the covariate “age” is not the covariate between global/local perceptual processing and skincare preference.

Managers can apply the findings to their targeting and communication strategies. First, it will be advantageous for managers marketing Asian skincare products to target Asian consumers with local perceptual processing style. For managers marketing Western skincare products in Asia, it will be better to target Asian consumers with global perceptual processing style. In terms of communication strategy development, managers marketing Asian skincare products to Asian consumers are recommended to encourage local perceptual processing, while managers marketing Western skincare brands to emerging Asian consumers should encourage global perceptual processing.

The value of this paper is that it applies the perceptual processing style to explain consumer decision-making in the context of consumers in emerging Asian countries. It also highlights a new perspective that helps managers craft targeting and communication strategies that help make their products to be perceived as a better fit or to facilitate consumer processing style so the product becomes a preferred choice.

The purpose of this paper was to investigate gender differences in entrepreneurship development.

A quantitative study consisted of an on-line questionnaire administered to a random sample of 206 owner-manager CEOs across Bosnia and Herzegovina. Various statistical tools were used in the analysis.

Empirical results revealed significant differences in entrepreneurial performance between women and men. It was found that gender significantly affects entrepreneurial activities in firms with regards to innovativeness, proactiveness and risk-taking. Overall, female respondents scored better in entrepreneurial dimensions than did males.

The state should support female entrepreneurship in the long term; aspirations exist, and this study’s results reveal this potential. Furthermore, it is recommended that women take a part in entrepreneurship development – a key to economic development. Also, it is suggested that education in entrepreneurship should be at a higher level than is currently the case.

This paper is the first empirical study that examines gender issues in entrepreneurship in Bosnia and Herzegovina. The study draws practical implications for current business owners, CEOs and potential entrepreneurs of either gender. This research removes stereotypes about female aspirations, competencies and skills in creating new start-ups and ventures, which in the long term will contribute to the economic development.

Although research on job insecurity (JI) and its relationship with employee performance has increased in recent years, results are mixed and inconclusive. The objectives of this paper are to explore 1) the conceptualizations of JI, 2) the relationship between JI and different performance dimensions, 3) the theoretical perspectives used to explain the JI–performance relationship and 4) the mechanisms and contextual boundaries that affect the JI–performance relationship.

Following the PRISMA guidelines, the authors systematically searched for peer-reviewed empirical studies published before July 2021 in Web of Science and Scopus. The authors analyzed 81 empirical studies published on the conceptualization of job insecurity, its relationship with employee performance, and what mechanisms and contingency factors are studied. The authors used thematic analysis to analyze the articles.

Results of this review show that the quantitative cognitive dimension is dominant in extant JI literature. Furthermore, in-role performance and OCB were most often investigated in relation to the four dimensions of job insecurity, drawing from a range of theoretical perspectives to explain this relationship. Moreover, a variety of mechanisms and contextual factors on individual, individual work-related, individual-level attitudes and job-level characteristics have found to play a role in this relationship.

This study has a number of limitations. The first pertains to the exclusion of articles in languages other than English and non-peer reviewed papers. It is possible that the search strategy used may not have identified other studies that may have met the established criteria in order to be included in our research. However, this method was chosen to guarantee the quality of the included articles in this study and in line with previous meta-analyses and literature reviews (De Witte et al., 2016; Sverke et al., 2019). Second, one selection criteria focused on how performance was assessed in the studies incorporated in this literature review. The authors excluded studies that addressed performance from the perspective of the organization (i.e. studies that measured performance at the organizational level). The authors herewith might have excluded studies that focused on one or multiple job insecurity constructs, but the authors herewith included studies that were comparable in terms of performance indicator outcomes. Future studies could expand the search by investigating, as a next step, the impact on organizational performance. Finally, since the focus of this literature review was on the relationship between job insecurity and performance indicators, including the mechanisms and boundary conditions that affect this relationship, the authors did not include focus on how job insecurity can be influenced (Shoss, 2017), and herewith lack information on the predictors side of job insecurity. However, by narrowing the authors focus to mediators and moderators, the authors were able to come up with an extensive list of factors that impact the job insecurity–performance relationship and herewith provide fruitful areas for future research. Future studies could expand these findings by providing an overview of predictors of different job insecurity constructs, to see whether there are potential different predictors of job insecurity conceptualizations (Jiang and Lavaysse, 2018).

The study review contributes to the systematization of the current empirical evidence on this area of research. This is especially important and enables room to take an additional step toward understanding the consequences of job insecurity on performance. Specifically, it is important for organizations and policymakers to be aware of the different conceptualizations of job insecurity that exist and how they impact employee performance. In addition, an overview of potential mechanisms and boundary conditions that affect this relationship provides insights as to how organizations can intervene to affect reactions to job insecurity.

The study findings are relevant and may be of interest to decision makers in organizations and national authorities that must have information on quality concerning the effects of job insecurity on performance.

Based on these findings the authors show the impact of the different conceptualizations of job insecurity and how they affect job performance. In addition, the authors provide recommendations for future studies how to better handle the integration of different conceptualizations and measures of job insecurity and its different approaches.
