Abstract
Purpose
The purpose of this paper is to develop a generic framework for hybrid (integrated deployment of system dynamics and discrete event simulation) simulation which can be applied in the healthcare domain.
Design/methodology/approach
As hybrid simulation in an organisational context is a new topic with limited available data on deployment of hybrid simulation in organisational context, an inductive approach has been applied. On the basis of knowledge induced from literature, a generic conceptual framework for hybrid simulation has been developed. The proposed framework is demonstrated using an explanatory case study comprising an accident and emergency (A&E) department.
Findings
The framework provided detailed guidance for the development of a hybrid model of an A&E case study. Findings of this case study suggest that the hybrid model was more efficient in capturing behavioural impact on operational performances.
Research limitations/implications
The framework is limited to only SD and DES; as agent‐based is another simulation method which is emerging as a promising tool for analysing problems such as spread of infectious diseases in healthcare context, inclusion of this into the framework will enhance the utility of the framework.
Practical implications
This framework will aid in the development of hybrid models capable of comprehending both detail as well as dynamic complexity, which will contribute towards a deeper understanding of the problems, resulting in more effective decision making.
Social implications
It is expected that this research will encourage those engaged in simulation (e.g. researchers, practitioners, decision makers) to realise the potential of cross‐fertilisation of the two simulation paradigms.
Originality/value
Currently, there is no conceptual framework which provides guidance for developing hybrid models. In order to address this gap, this paper contributes by proposing a conceptual framework for hybrid simulation for the healthcare domain.

Abstract
Purpose
This study seeks to understand the nexus between intellectual capital and profitability of healthcare firms in India with interaction effects.
Design/methodology/approach
Relevant data were extracted from the Centre for Monitoring Indian Economy (CMIE)'s Prowess database for a period of ten years 2009–2018 for a sample of 84 selected firms from the healthcare industry. This study uses value added intellectual coefficient (VAIC) and modified value added intellectual coefficient (MVAIC) as a measure of intellectual capital. Further, the study employs panel regression techniques to explore the relationship between intellectual capital and profitability.
Findings
The empirical findings reveal that the intellectual capital coefficient of healthcare firms in India averages 2.7757. It is also observed that a majority of the healthcare firms' intellectual capital coefficient is below the industry average. From the regression analysis, it is evident that the intellectual capital coefficient is positively related to the profitability of healthcare firms in India. As far as the components of intellectual capital coefficient are concerned, the capital employed coefficient (CEC) is the only component driving the profitability of healthcare firms in India. A further introduction of interaction terms improves model explainability and moderates the impact of the predictor variable on the response variable. Furthermore, it is observed that the intellectual capital coefficient of the healthcare industry is immune to changes in political regimes in India.
Practical implications
The findings reveal that intellectual capital is an important driver of corporate performance, thus healthcare firms in developing economies like India need to enhance their intellectual potential. Therefore, corporates and governments in developing economies should stimulate investments in developing intellectual capital for enhanced corporate performance and economic growth. Thus, this study might be used as a reference by policymakers while drafting the future policy for the development of intellectual capital in general and healthcare sector specifically.
Originality/value
This is among the first few studies to explore such an empirical relationship for healthcare firms in India and among the few studies of this kind across the globe. It also makes novel contributions in considering interaction variables and seeking the consistency of results across different political regimes. However, the study examines one nation and one industry; thus, the generalisation of findings requires caution.

Abstract
Purpose
This article aims to propose guidelines to develop moderation hypotheses, assess moderators using the multigroup analysis and interaction effect approaches and interpret the results of moderation analysis in tourism and hospitality research.
Design/methodology/approach
Through a review of 600 articles published in top tourism and hospitality journals from the year 2016 to 2020, and reviewing the literature related to moderation analysis, this study identifies key issues in different steps of moderation analysis and proposes robust guidelines to aid future research.
Findings
The results of the systematic review uncovered some key issues in different steps of moderation analysis, such as hypothesis development, moderation assessment and results interpretation. The findings emphasized the typical methodological misconceptions and improper practices for moderation analysis.
Research limitations/implications
Moderation analysis is of great significance to the advancement of theory, and its application has increased significantly in recent years. However, many studies appear to have a limited understanding of moderation analysis and follow questionable practices regarding hypothesis development, moderation assessment and results interpretation, thus leading to suspicious conclusions for theory advancement. By highlighting these methodological issues, this article provides robust guidelines for moderation analysis, which is of great theoretical and methodological significance to the academic research in tourism and hospitality.
Originality/value
As one of the first studies to provide robust guidelines for moderation analysis, based on a critical and systematic review of papers published in top-tier journals in tourism and hospitality and the latest developments on moderation analysis in the wider literature, this article has important theoretical and methodological significance for the academic research in tourism and hospitality as well as general social science disciplines.

Abstract
Purpose
The purpose of this paper is to explain how to model moderating effects of composites using partial least squares (PLS) path modeling. It provides the methodological underpinning of moderating effects in general and describes the various approaches for forming the interaction term, i.e., the product indicator approach, the two-stage approach, and orthogonalization.
Design/methodology/approach
The paper discusses the use of standardized vs unstandardized construct scores and introduces spotlight analysis as a useful way to report findings.
Findings
Researchers should rely on unstandardized estimates when analyzing moderating effects. Centering or orthogonalization can help improve the interpretability of path coefficients.
Practical implications
PLS software implementations should facilitate unstandardized estimates.
Originality/value
This paper formulates step by step guidelines for analyzing moderating effects of composites using PLS path modeling. It is the first to propose spotlight analysis for PLS path modeling.

Abstract
Purpose
This paper aims to investigate the ways that could enhance residents’ social interaction in low-rise residential building neighbourhoods of Basra city in Iraq. The lack of social interaction among residents of Basra city prompted the authors to frame a strategy for this case study.
Design/methodology/approach
The spatial design characteristics of low-rise residential building neighbourhoods implicated to support the residents in terms of social interactions in comparison to those exhibited by a single home and traditional neighbourhoods. The statistical data demonstrated that by using this strategy, several unique features of secured, collective, responsive and supportive spaces could enhance the residents’ social interaction.
Findings
This study found that all collective space factors have a significant influence on social interaction. “Fostering proper proximity and accessibility” factor was ranked first and the most significant factor with an influence on social interaction. Secured spaces (hierarchical spatial structure, physical security supports and construct) have a significant influence on social interaction. The most interesting finding in this study is that all factors of the supportive spaces construct have a significant influence on social interaction. Finally, this study showed that two factors of the responsive spaces construct, increasing variety and increasing legibility, have an insignificant influence on social interaction.
Originality/value
The design of low-rise residential building neighbourhoods in Basra city may be used to develop social interaction as the contributing factor for maintaining values of traditional neighbourhood communities. This study highlights certain recommendations for architects, especially urban designers, to reinforce residents’ social interaction in low-rise residential building neighbourhoods in Basra city.

Abstract
This paper is a study of competitive and cooperative interactions among members of a competitive industry group. There are few strategic, tactical or market moves that do not affect competition in any industry. Competitive and cooperative interactions among competitive firms are studied to determine how the reactions of competitors to an initiator of an action cause convergent or divergent patterns. It is hypothesized that the patterns, or cycles, of competitive and cooperative interactions are a function of complexity of the interaction cycle, degree of offensiveness of participants’ moves, action reversibility, previous interaction experience, interaction cycle visibility and response time. An empirical test of the hypothesis revealed that the two most strongly supported hypotheses were: interaction cycle complexity increases the likelihood of interaction cycle convergence, and interaction cycle visibility increases the likelihood of interaction cycle divergence.

Abstract
The pace of organizational and environmental change seems to demand that such professional organizations as CPA firms become learning organizations in order to compete adequately with other firms. The flattening out of traditional hierarchical structures within organizations argues that traditional mentoring and supervisory structures may be inadequate for fostering needed individual learning and personal learning. One effect of the lack of such learning may be increased role stress, job burnout, loss of commitment to the organization, intention to leave, and diminished job satisfaction. Using a sample of 440 accounting professionals from major CPA firms in several regions of the USA, studies the ability of team social interaction processes within work teams to foster the personal, organizational, and team‐source learning, and also to influence attitudinal outcomes directly and indirectly. Also examines whether personal learning, organizational socialization and team‐source learning mediate the impact of team social interaction process on attitudinal outcomes. Uses a hierarchical regression‐based test to evaluate our hypotheses. The results supported our expectations. A structural equation modeling test of the model showed that organizational and personal learning mediated the relationship between team social interaction processes and the attitudinal outcomes, but team‐source learning did not.

Abstract
Purpose
This study examines dynamics of global and regional financial market efficiency; and how specific features of the market and other conditions influence variability in such efficiency.
Design/methodology/approach
The study employs fixed effects statistical approach in its examination of how specific features of financial markets influence variability in its efficiency.
Findings
This study finds that individual IMF defined economic regions tend to exhibits significantly different financial market efficiency characteristics given specific market features and conditions. In regional level comparative analysis (e.g. Europe, Africa, Asia–Pacific etc.) this study finds that incidence of financial market uncertainty is the dominant condition with significant effect on financial market efficiency across all the IMF regions. In the global level analysis, empirical estimates presented suggest that financial market uncertainty, financial institutional depth and financial institutional efficiency tend to have significant positive influence on global financial market efficiency all things being equal. In the same analysis however, this study finds that financial market and financial institutional access growth has significant negative impact on financial market efficiency.
Originality/value
The uniqueness of this study compared to related ones found in the literature stems from its focus on financial market efficiency at the global, and IMF defined regional block level instead of on a specific economy as often found in the literature. Additionally, in contrast to other related studies, this study further examines the role of global financial market uncertainty in its financial market efficiency analysis. Financial market uncertainty variable may be unique to this study because the variable is derived through an econometric process from a base variable.

Abstract
Purpose
The purpose of this research is to extend theoretical knowledge of key variables and their interactions that impact the persuasiveness of online influencers. The study explores the interactions between influencer gender, follower gender, influencer physical attractiveness, influencer product-match and influencer-follower homophily on persuasiveness of influencer product promotions. Although the extant literature shows the persuasive impact of attractiveness, product-match, gender and homophily, less is known about the interactions of these variables with each other and the gender of the influencer and his or her followers. These gaps in the literature are explored.
Design/methodology/approach
The study is a scenario-based experiment where respondents were randomly assigned to cells where influencer attractiveness and product-match were manipulated. The variables of homophily and respondent gender were measured and recorded, respectively. The data were collected through an online survey done through Qualtrics.
Findings
The findings show that for female influencers, homophily felt by their followers is a dominant persuasive factor, which tends to supersede the variables of attractiveness and product-match. For male influencers, homophily is an incremental persuasive variable. That is, homophily, attractiveness and product-match interact such that persuasiveness is highest when all three variables are strong.
Research limitations/implications
Limitations are that the authors used a student sample and a hypothetical scenario-based experiment. Theoretical implications are interesting in that the authors have results which add to theory on the factors that make an online influencer more persuasive. Specifically, the authors contribute by extending theoretical knowledge about the interactions of key variables that influence the impact of online influencers.
Practical implications
For a manager marketing products using influencers, it is very important to stress homophily cues for female influencers more than other variables. However, for male influencers, product knowledge or match, homophily and attractiveness all need to work simultaneously to maximize influencer persuasiveness.
Social implications
One needs to understand that physical attractiveness and perceived homophily with the influencer have significant influence and persuasiveness, regardless of product or service. Hence, there needs to be social responsibility in what is advertised and promoted, given that followers may be persuaded by influencers no matter what the product or service is.
Originality/value
To the best of the authors' knowledge, this is the first study that explores the persuasiveness of online influencers from the perspective of the variable interactions described above.
