Abstract
Purpose
This study intends to investigate how an employee's proactive personality and a supervisor's idiosyncratic deals (i-deals) relate to their subordinates' affective commitment (AC) and occupational well-being (OWB), in light of the mediating role of subordinates' i-deals, using proactive motivation theory and the job demand–resource (JD-R) model as theoretical foundations.
Design/methodology/approach
The study consisted of 342 employees working in the hospitality industry. To examine the proposed model, the researchers used the structural equation modelling approach and bootstrapping method in AMOS.
Findings
The results affirmed the influence of subordinates' proactiveness on AC and OWB, but no direct influence of supervisors' prior i-deals on subordinates' AC and OWB was established. When investigating the mediational role of subordinates' i-deals, a partial mediation effect was found between subordinates' proactive personality with AC and OWB, whereas full mediation was established between supervisors' i-deals and subordinates' AC and OWB.
Practical implications
These findings shed light on how i-deals improve AC and OWB for both groups of supervisors and subordinates. In an era of increasing competition amongst organizations operating within the hospitality industry, i-deals serve as a human resource strategy to recruit, develop and retain talented individuals.
Originality/value
The novelty of this research lies in its specific investigation of the combined influence of proactive personality as an individual factor and supervisors' i-deals as an organizational factor on subordinates' i-deals within the context of the hospitality industry. Furthermore, it aims to analyse the potential impact of these factors on AC and OWB.

Abstract
Purpose
In the wake of the COVID-19 pandemics, the demand for innovative and effective methods of bacterial inactivation has become a critical area of research, providing the impetus for this study. The purpose of this research is to analyze the AuNPs-mediated photothermal inactivation of E. coli. Gold nanoparticles irradiated by laser represent a promising technique for combating bacterial infection that combines high-tech and scientific progress. The intermediate aim of the work was to present the calibration of the model with respect to the gold nanorods experiment. The purpose of this work is to study the effect of initial concentration of E. coli bacteria, the design of the chamber and the laser power on heat transfer and inactivation of E. coli bacteria.
Design/methodology/approach
Using the CFD simulation, the work combines three main concepts. 1. The conversion of laser light to heat has been described by a combination of three distinctive approximations: a- Discrete particle integration to take into account every nanoparticle within the system, b- Rayleigh-Drude approximation to determine the scattering and extinction coefficients and c- Lambert–Beer–Bourger law to describe the decrease in laser intensity across the AuNPs. 2. The contribution of the presence of E. coli bacteria to the thermal and fluid-dynamic fields in the microdevice was modeled by single-phase approach by determining the effective thermophysical properties of the water-bacteria mixture. 3. An approach based on a temperature threshold attained at which bacteria will be inactivated, has been used to predict bacterial response to temperature increases.
Findings
The comparison of the thermal fields and temporal temperature changes obtained by the CFD simulation with those obtained experimentally confirms the accuracy of the light-heat conversion model derived from the aforementioned approximations. The results show a linear relationship between maximum temperature and variation in laser power over the range studied, which is in line with previous experimental results. It was also found that the temperature inside the microchamber can exceed 55 °C only when a laser power higher than 0.8 W is used, so bacterial inactivation begins.
Research limitations/implications
The experimental data allows to determinate the concentration of nanoparticles. This parameter is introduced into the mathematical model obtaining the same number of AuNPs. However, this assumption introduces a certain simplification, as in the mathematical model the distribution of nanoparticles is uniform.
Practical implications
This work is directly connected to the use of gold nanoparticles for energy conversion, as well as the field of bacterial inactivation in microfluidic systems such as lab-on-a-chip. Presented mathematical and numerical models can be extended to the entire spectrum of wavelengths with particular use of white light in the inactivation of bacteria.
Originality/value
This work represents a significant advancement in the field, as to the best of the authors’ knowledge, it is the first to employ a single-phase computational fluid dynamics (CFD) approach specifically combined with the thermal inactivation of bacteria. Moreover, this research pioneers the use of a numerical simulation to analyze the temperature threshold of photothermal inactivation of E. coli mediated by gold nanorods (AuNRs). The integration of these methodologies offers a new perspective on optimizing bacterial inactivation techniques, making this study a valuable contribution to both computational modeling and biomedical applications.

Abstract
Purpose
Drawing on the job demands-resources theory, this study investigates the mediating role of job satisfaction and the moderating roles of abusive supervision and perceived organisational support (POS) in the relationship between perception of organisational politics (POP) and employee job performance. This study hypothesised that employees with high POS and low abusive supervision can function effectively even in organisations with a high level of organisational politics.
Design/methodology/approach
The study was conducted anonymously on 408 employees, from companies operating in Poland which were completed using the computer-assisted telephone interview method. Statistical verifications of the moderation and mediation analyses were conducted with PROCESS macro.
Findings
The results showed that a high level of POP does not diminish employee performance when employees perceive low levels of abusive supervision and a high level of POS. Furthermore, the results revealed that job satisfaction mediates between POP and employee performance.
Originality/value
This study integrated research on politics, abusive supervision and POS to examine the collective impact of these variables on employee performance. The findings have important implications in terms of the potential buffering that can be applied to reduce the negative impacts resulting from POP.

Abstract
Purpose
The purpose of this paper is to provide insights into cross-functional team (CFT) members’ points of view on knowledge integration.
Design/methodology/approach
This study was conducted using Q methodology. The 22 respondents were members of CFTs in information systems development within 7 agencies of the Flemish Government administration.
Findings
The study resulted in three distinct perspectives. To the CFT player, the benefits and added value of information and knowledge diversity of CFTs outweigh the challenges of knowledge integration. By contrast, the CFT sceptic is doubtful that knowledge integration in CFTs can ever work at all. Finally, the organization critic highlights the lack of support from the organization for efficient and effective knowledge integration in CFTs.
Research limitations/implications
The findings of this study suggest that CFT configurations have important implications for the development of shared team mental models and for teams’ cognitive performance.
Practical implications
Making CFT members aware of their peers’ mental models, ways of working and priorities could help strengthen knowledge integration. To improve knowledge integration in teams, managers should reduce knowledge boundaries that are the result of organizational structuring and power play between departments.
Originality/value
By focusing on daily experiences with knowledge integration, this study reveals that members of CFTs in information systems development hold contrasting perspectives on, and diverging attitudes towards, knowledge integration.

Abstract
Purpose
The present study aimed to explore the socio-psychological linkages between perceived job insecurity, loneliness, social support, depression, and interpersonal misconduct among hotel workers during a global crisis. The primary motivation behind this research was the significant problem of increased occupational stress resulting from the negative consequences of the pandemic on all hotel employees, including frontline workers and management personnel. This study aimed to investigate the impact of the pandemic on occupational stress within the hotel sector.
Design/methodology/approach
This research obtained 269 original survey data from employees in the Indian hotel industry by distributing a questionnaire and employing a convenience sampling method. Subsequently, the data were examined using (SEM).
Findings
The research findings suggest that there is a positive correlation between interpersonal deviance and depression. Additionally, this study demonstrated that social support can alleviate loneliness but has no significant association with depression.
Research limitations/implications
This study can help hotel managers create guidelines that address the perceived insecurity and psychological issues faced by employees.
Originality/value
By understanding the psychological position of their employees, hoteliers can implement strategies to mitigate the negative impacts of the pandemic on their workforces.

Abstract
Effectively managing an intermodal logistics network has become a significant strategic consideration in international logistics. This study aims to empirically examine the way in which intermodal logistics network coordination can be successfully developed and sustained, and to analyze whether the highly coordinated intermodal logistics network may facilitate the greater logistics performance of network players as well as of the entire intermodal logistic network system. This study adopts social network embeddedness perspective to examine the determinants facilitating the higher level of coordination of the intermodal logistics network. An explorative interview method is being employed for the empirical analysis, and the results show that strong, dense and bridging ties within the network mechanisms facilitate a greater intermodal logistics network coordination. As a result, this helps to enhance the logistics performance of the intermodal logistics network system and its players by facilitating the enhancement of logistics services effectiveness and operational efficiency.

The study aims to investigate the persistence of seasonal anomalies during religious holidays in emerging markets.
Abstract
Purpose
The study aims to investigate the persistence of seasonal anomalies during religious holidays in emerging markets.
Design/methodology/approach
The authors select the Bombay Stock Exchange and National Stock Exchange stock returns from January 1990 to December 2022. The GARCH family models were adopted to examine the mean-variance returns associated with symmetric and asymmetric effects. The ARIMAX model is used to investigate the exogenous order during the pre-mandated and post-mandated trading holidays.
Findings
The results show that the persistence of returns and volatility during religious holidays significantly when subjected to specific religious holidays. The authors also found that volatility during religious festivals dipped during the pre-holiday and gradually increased after the events. The findings suggest that religious holiday anomalies exhibit a trivial significant effect on stock market returns and this effect is waning.
Research limitations/implications
The findings provide investors and market regulators with a better understanding of market anomalies related to religious practices. During these periods, investors may experience substantial fluctuations in their portfolios, potentially leading to significant losses or payoffs. Investors can sustain substantial losses or payoffs and market manipulation by adjusting their strategies around religious holidays to account for potential volatility, albeit temporarily.
Originality/value
This study contributes to behavioural finance literature that suggests that beliefs and cultural aspects determine a country’s stock market inefficiency. To the best of the authors’ knowledge, no previous study has comprehensively examined threshold religious holidays across diverse religions in Indian market using long-memory data.

Abstract
Purpose
There has been very little qualitative “fieldwork” of audit practice. This is especially the case in relation to investigations into how audit engagements proceed. The purpose of this paper is to engage with audit practice in order to explore and explain the internal dynamics and paradoxical conditions within audit engagement teams.
Design/methodology/approach
The research adopts a qualitative methodology, framed around an intensive case study that involves several methods of data collection and analysis including interviews, observation and document analysis. The authors observe audit team practices, work programmes and organisation including observations of individual and teams involved in audit engagements.
Findings
Using the lens of paradox theory, the authors explore the backstage of audit work, where audit teams are challenged with recurring contradictory requirements and opposing demands. The authors provide insight on the complexity associated with inadequate resourcing and planning that tend to stimulate the emergence of paradoxes in audit engagement work in a government audit context. As a result, the authors identify the occurrence of cascading reduced audit quality practices (RAQP) as the teams respond to the paradoxes they face.
Originality/value
The authors reveal the interlinked and cumulative coping strategies, namely, downplaying responsibility and downscaling audit processes. These strategies are performed concurrently by team leaders and audit members to manage paradoxical tensions. The authors also identified superficial audit supervision as another type of RAQP performed by team leaders.

Abstract
Purpose
Distance has been a core concept and issue in international business and management research. While scholars argue that distance through internationalization is increasing costs, distance is also associated with positive implications such as the integration of more diverse knowledge. Still, many firms struggle to manage distance effectively and efficiently in their multinational contexts. The purpose of this study therefore is to propose Open Strategy – increasing transparency and inclusion in the strategy process – as an attractive concept for managing distance.
Design/methodology/approach
This is a conceptual paper where the authors introduce Open Strategy to the IB community.
Findings
The authors argue that opening the strategy of multinational enterprises, enables firms to leverage diversity by re-combining the firms diverse and distant knowledge. It also reduces distance by moving beyond formal mechanisms of control and coordination to improve joint understanding, cooperative commitment and strategy implementation. The framework shows how firms can move beyond established dogmas in international business research by rendering their strategy processes more open.
Originality/value
Leveraging the Open Strategy literature, the authors are able to find a way to respond to the challenge of increasing distance, in fact even arguing that distance can be beneficial if framed as diversity.

Abstract
Purpose
The purpose of this paper is to explore two distinct subsets of dynamic capabilities that need to be deployed when pursuing innovation through inter-organizational activities, respectively, in the contexts of broad networks and specific alliances. The authors draw distinctions and explore potential interdependencies between these two dynamic capability reservoirs, by integrating concepts from the theoretical perspectives they are derived from, but which have until now largely ignored each other – the social network perspective and the dynamic capabilities view.
Design/methodology/approach
The authors investigate nanotechnology-driven R&D activities in the 1995–2005 period for 76 publicly traded firms in the electronics and electrical equipment industry and in the chemicals and pharmaceuticals industry, that applied for 580 nanotechnology-related patents and engaged in 2,459 alliances during the observation period. The authors used zero-truncated Poisson regression as the estimation method.
Findings
The findings support conceptualizing dynamic capabilities as four distinct subsets, deployed for sensing or seizing purposes, and across the two different inter-organizational contexts. The findings also suggest potential synergies between these subsets of dynamic capabilities, with two subsets being more macro-oriented (i.e. sensing and seizing opportunities within networks) and the two other ones more micro-oriented (i.e. sensing and seizing opportunities within specific alliances).
Practical implications
The authors show that firms differ in their subsets of dynamic capabilities for pursuing different types of inter-organizational, boundary-spanning relationships (such as alliances vs broader network relationships), which ultimately affects their innovation performance.
Originality/value
The authors contribute to the growing body of work on dynamic capabilities and firm-specific advantages by unbundling the dynamic capability subsets, and investigating their complex interdependencies for managing different types of inter-organizational linkages. The main new insight is that the “linear model” of generating more innovations through higher inter-firm collaboration in an emerging field paints an erroneous picture of how high innovation performance is actually achieved.
