Discusses computational challenges in air quality modelling (as viewed by the authors). The focus of the paper will be on Di, the “current” state‐of‐affairs. Owing to limitation of space the discussion will focus on only a few aspects of air quality modelling: i.e. chemical integration, sensitivity analysis and computational framework, with particular emphasis on aerosol issues.

A worker with a proactive personality actively pursues changes in the environment instead of maintaining the status quo, leading to an expected result of a negative relationship between proactive personality and psychological withdrawal behaviors. The authors propose that based on the trait activation theory (TAT), this negative relationship is moderated by servant leadership.

Empirical data collected from subway station workers in three metropolitan cities in South Korea supported all the hypothesized relationships. Even though the workers are not public servants, the subway companies are owned by three metropolitan cities. With reliability and validity tests for the measurements, the authors performed an ordinary least square (OLS) hierarchical multiple regression analysis for hypotheses testing.

A multilevel analysis showed that the higher a worker's proactive personality is, the less likely it is that he/she shows withdrawal behaviors at work and that the negative relationship between the two is stronger under servant leadership. An organization pursuing maximization of its members' proactive personality may find an advantage in servant leadership.

First, the data was collected from three metropolitan city-owned companies, which may have different work attitudes and behaviors. Second, the authors hypothesized and found a negative relationship between the predictor and the dependent variable. To apply TAT more appropriately, the dependent variable could have been a positive work behavior showing a positive relationship between the predictor and the dependent variable.

The results of this study have both theoretical and empirical implications. In terms of theoretical implication, the study rather indirectly supports TAT. While Greenbaum et al. (2017) demonstrated the triggering effect of abusive supervision on employees' Machiavellianism, which leads to unethical behaviors, this study showed a stronger negative relationship between proactive personality and psychological withdrawal behaviors. This study provided empirical evidence showing servant leadership's role in lowering negative behaviors. This study's findings suggest how an organization could maximize the benefits of members' proactive personality under high servant leadership.

The purpose of this paper is to estimate the direct effects of foreign direct investment (FDI) on domestic target firms’ profitability gains, in India, post-acquisition. In particular, it focuses on identifying the importance of firms’ heterogeneities on the effects, taking into account the source of FDI, the intensity of firm interaction, and the target firms’ technology-absorptive capacity. Most importantly, the paper investigates whether the estimates depend on a combined rather than single impact of these heterogeneities.

To control for the possibility of selection bias and endogeneity, this empirical analysis uses a methodology that combines propensity score matching and difference-in-differences (PSM–DID) in adopting a comprehensive data set of both foreign- and Indian-acquired firms that were purchased through mergers and acquisitions in India between 1991 and 2013.

The analysis reveals four major findings. First, overall, the post-foreign acquisition target firms’ performance gains were positive and varied by the heterogeneous technology transfer capacity of the foreign investor. Second, it is possible that target firms located in industrial clusters with more foreign agglomeration experienced larger profitability gains through more dynamic firm interactions in terms of spillovers. Third, Indian targets with higher technology-absorptive capacity benefitted in higher profitability gains from acquiring and assimilating the superior technology that is transferred from foreign investors. Finally, an optimal combination of Indian target firms with higher technology-absorptive capacity and foreign investors with higher technology transfer capacity maximizes profitability gains, post-acquisition. This synergy effect is particularly prominent in clusters where more foreign firms agglomerate.

This study captures the true direct effect of FDI by adjusting the combined causal effects of various inherent heterogeneities in the target firms’ performance, thus correcting any possible bias, which few previous studies have addressed.

This paper aims to study the different infill, printing direction against sliding direction and various load condition for the friction and wear characteristics of polylactic acid (PLA) under reciprocating sliding condition.

The tests were performed by applying the load of 1, 5, 15 and 10 N with sliding oscillation frequency of 10 Hz for the duration of 10 min at room temperature.

The results show that the friction and wear properties of PLA specimen change with a different infill density of printed parts. The oscillation frequency is 10 Hz and the infill density of plate is 50 per cent that shows the best friction and wear properties.

The potential of this research work is to investigate the tribological characteristics of three-dimensional printing parts with different infill percentage to provide a reference for any parts in contact with each other to improve friction and wear performance. There will be many opportunities exist for further research and the advancement of three-dimensional printing in the field of tribology.

This paper explores the entrepreneurial transformation of Bangtan Sonyeondan or Bangtan Boys (BTS), tracing their journey from initiation through expansion. Despite the global prominence of their music, dance and outreach, many aspects of BTS’s meteoric rise remain underexplored. This study aims to illuminate the strategic and organizational developments that have propelled their unprecedented growth in the global media landscape.

Using case study research methods, this paper uses a multimodal approach to examine BTS’s intricate interactions with market dynamics and fan engagement comprehensively. Using entrepreneurial innovation as the overarching theoretical framework, the authors categorize BTS’s transformational processes into drivers, practices and outcomes, thereby elucidating the strategies used to navigate key challenges and pivotal moments in their worldwide ascent.

The BTS organization exhibits a distinct entrepreneurial orientation and transformation process across its phases of initiation, development, growth and expansion. The authors identify specific drivers, practices and outcomes along with strategic vision, actionable practices and measurable performance outcomes at each stage.

While this study draws valuable parallels between BTS’s trajectory and established growth models, it recognizes the limitations inherent in a single-case study approach. The findings highlight the critical role of entrepreneurial leadership in the entertainment industry and suggest further exploration into the universal applicability of these models across different genres and cultural contexts within the music industry.

This paper underscores the importance of entrepreneurial innovation within entertainment organizations. The conceptual framework provided can assist managers in formulating strategies and policies for the growth and transformation of similar entities.

BTS’s case demonstrates how engaging a global audience with culturally specific content and the universal appeal of youthful energy can be transformative. This engagement is facilitated through effective use of music, dance and dynamic interactions on social media.

By analyzing BTS from an entrepreneurial leadership perspective, this study offers unique insights by examining their internal motivations and managerial practices, as well as the external outcomes, spanning from 2010 to 2023.

The present chapter explores the topic of death in the context of contemporary New Delhi, India. Building upon what I chose to call an ‘expanded ethnography’, it explores the multiple ways in which sensory, visual and digital mediations and tools can help researchers address such an existentially delicate topic. Building on a mix of online visual ethnography (of computer screens and smartphones), of bodily/sensory practices, of sound recording and image-making, my research focussed on retirement homes and shelters amidst a bulging Indian metropolis. I engaged with subjects who, because of personal choices or family difficulties, have ended up finishing their lives in solitude amidst a city forced to co-live with the presence of death. Alternating between photographic portraits, filmic observations and moments of playful exchanges in front of a camera (with me as one of the objects portrayed) my method capitalizes upon the integration (and problematisation) of bodily (sensory and affective) as well as digital techniques. All together these different mediations have granted me access to different layers of connection to the topic of death in Delhi and also to my ageing guides/interlocutors.

This paper investigates the determinants of the capital structure of large corporations headquartered in the United States and Korea. We consider five explanatory variables: profit, company size, non‐debt tax shields, growth, and business‐risk, along with several industry indicator variables as independent variables and examine, for each country, the relationship to market value based leverage ratio. With our rigid criteria for inclusion in the study, we study the top thirteen companies (by size) in each of seven industries. The majority of our findings indicate that we can generalize to Korea what has been found for Japanese companies/industries relative to the U.S.

While conceived to examine key factors affecting post-retirement career advancement of retired elite athletes in South Korea, the purpose of this paper is to report how English, as a de facto global lingua franca, functions as a powerful gatekeeper in the sports administration field.

Interpreted through the lens of Bourdieu’s linguistic capital and Gramsci’s hegemony of language, the present study draws on content analysis of semi-structured individual interviews, as well as focus group interviews, conducted with thirty former South Korean elite athletes.

Based on the data analysis, systematic bias toward athletes was uncovered, privileging English as the single determining factor for employment. Furthermore, the educational implications for adult learners of English as a Foreign or English an Additional Language reveal unrealistic expectations of top–down language policies.

Perspectives of athlete participants, an underrepresented group in educational research, within the South Korean globalization context shed critical light on the pervasive aspects of English hegemony and its unexamined dimensions.

The purpose of this research is to explain the influence of information security monitoring and other social learning factors on employees’ security assurance behaviour. Security assurance behaviour represents employees’ intentional and effortful actions aimed towards protecting information systems. The behaviour is highly desired as it tackles the human factor within the information security framework. The authors posited that security assurance behaviour is a learned behaviour that can be enhanced by the implementation of information security monitoring.

Theoretical framework underlying this study with six constructs, namely, subjective norm, outcome expectation, information security monitoring, information security policy, self-efficacy and perceived inconvenience, were identified as significant in determining employees’ security assurance behaviour (SAB). The influence of these constructs on SAB could be explained by social cognitive theory and is empirically supported by past studies. An online questionnaire survey as the main research instrument is adopted to elicit information on the six constructs tested in this study. Opinion from industry and academic expert panels on the relevance and face validity of the questionnaire were obtained prior to the survey administration.

Findings from this research indicate that organisations will benefit from information security monitoring by encouraging security behaviours that extend beyond the security policy. This study also demonstrates that employees tend to abandon security behaviour when the behaviour is perceived as inconvenient. Hence, organisations must find ways to reduce the perceived inconvenience using various security automation methods and specialised security training. Reducing perceived inconvenience is a challenge to information security practitioners.

There are some limitations in the existing work that could be addressed in future studies. One of them is the possible social desirability bias due to the self-reported measure adopted in the study. Even though the authors have made every effort possible to collect representative responses via anonymous survey, it is still possible that the respondents may not reveal true behaviour as good conduct is generally desired. This may lead to a bias towards favourable behaviour.

In general, the present research provides a number of significant insights and valuable information related to security assurance behaviour among employees. The major findings could assist security experts and organisations to develop better strategies and policies for information security protection. Findings of this research also indicate that organisations will benefit from information security monitoring by encouraging security behaviours that extend beyond the security policy.

In this research, the social cognitive learning theory is used to explain the influence of information security monitoring and other social learning factors on employees’ security assurance behaviour; the finding implies that monitoring emphases expected behaviours and helps to reinforce organisational norms. Monitoring may also accelerate learning when employees become strongly mindful of their behaviours. Hence, it is important for organisations to communicate the monitoring practices implemented, even more imperative whenever security monitoring employed is unobtrusive in nature. Nonetheless, care must be taken in this communication to avoid resentment and mistrust among employees.

This study is significant in a number of ways. First, this study highlights significant antecedents of security assurance behaviour, which helps organisations to assess their current practices, which may nurture or suppress information security. Second, using users’ perspective, this study provides recommendations pertaining to monitoring as a form of information security measure. Third, this study provides theoretical contribution to the existing information security literature via the application of the social cognitive learning theory.
