Head-mounted display (HMD)-based virtual reality (VR) is ideally suited for presence and generating compelling visual experiences of self-motion, but users can suffer from side effects associated with head-to-display lag. We used the Oculus Rift HMD (consumer release – CV1) to simulate forward self-motion in depth. Observers made continuous yaw head movements at approximately 0.5 Hz or 1.0 Hz while viewing these self-motion simulations. We examined the perceptual effects of increasing the display lag, by adding lag to the baseline lag of the system (estimated to be approximately 5.3 ms or 0.5 frames per second). We found that increasing the head-to-display lag up to 212 ms reduced the presence and the strength of vection. In addition, faster (1.0 Hz) head oscillations were found to generate weaker presence and vection in the virtual environment than the slower (0.5 Hz) head oscillations. We also found that a positive correlation between vection and presence (found previously) persists across a wide range of head-to-display lags, and, increasing lag from a very low baseline level still impaired both experiences. Both vection and presence in virtual environments can therefore be impaired by either increasing head-display lag or making more rapid angular head movements.

With the increased participation of emerging economies in the global economy, born globals (BGs) in emerging countries become significant players. However, researches on Chinese BGs are still very limited. The aim of this paper is to explore the key factors that influence the rapid internationalization of Chinese BGs and examine how these factors can explain the successful and quick integration of Chinese BGs into global market. Based on an Anglo-Saxon literature review, we identified six major factors explaining BGs’ rapid internationalization and compared them on two groups of Chinese SMEs (BGs and non-BGs) in an exploratory study. Based on the analysis of the exploratory study, we identified two key factors for the rapid internationalization of Chinese BGs, namely managers and networks. Then, we select four Chinese BGs and conducted a comparative case study in order to examine and understand the role of these two factors in their internationalization process. We conclude this paper with the contribution, implication, and limitation of our study, as well as the perspective for our future research.

The objective of this paper is to determine the managerial governance characteristics related to financial distress companies. The boards failed to accomplish their monitoring duties, which seemed to be one of the main reasons behind the actual financial distress and bankruptcy that swept the companies across the planet. Through the analysis of a sample of 178 Lebanese non listed and owned family firms, the results showed that the boards (that have a higher proportion of outside directors) are less inclined to face a financial distress than the boards with a lower proportion. Besides, a different conclusion proves that the board’s size and financial distress are directly linked. The paper highlights the extent to which financial distress is associated with corporate governance from a Euro Mediterranean country. It would be a source of education to Lebanese investors who excessively go for short-term returns and of help for regulatory authorities in the framework of making policies on corporate governance reformation.

Purpose The purpose of this paper is to answer the following question: what motivates refugees to create their own businesses in a developing country, and how do they go about it? Design/methodology/approach A quantitative study was conducted before Syrian refugees in main camps in Lebanon. The self-administrated survey was translated into the Arabic language to fit the respondents understanding of the questions asked and answers choices. Closed questions with nominal ratio and Likert scales were used to gather the primary data in the line of the study of Wauters and Lambrecht. The data were analysed with a logistic regression analysis under SPSS. Findings The findings show that 71 per cent of Syrian refugees seem to have a willingness to start a new business in Lebanon. The respondents are mostly young, with 62 per cent being between the ages of 18 and 35. Most of them are men (66.67 per cent) against 33.33 per cent of women. 60 per cent have already been entrepreneurs, and they are mostly motivated by earning a living but in the sector they used to work in before in their home country. Finally, the obstacles seem to be linked to financial and administrative issues, but also to the local policies. However, the fact that they share some cultural values with Lebanese such as the language or food, allow them to integrate easier and to create social bonds. Research limitations/implications The research is limited by the fact that the authors cannot generalise the findings since the Lebanese environment is very different from other countries’ environment. Besides, the Syrian refugees share already a lot of values and lifestyle with Lebanese. So, the authors cannot transpose their case to other ethnic population. Also, the study is limited by the lack of a gender statement and the link between the education level and the decision of creating a new business. Practical implications The authors propose some recommendations to the Lebanese Government and NGOs in order to facilitate and support the entrepreneurship actions of refugees shortly after they arrive to Lebanon. Social implications This paper confirms the importance of social ties in encouraging entrepreneurship in the case of refugees. Originality/value In this paper, the authors make four contributions to the academic debate: first, the authors studied the entrepreneurial motivations of refugees in a middle-eastern developing country while the other studies have focussed upon the adaptation of such individuals in a western and developed environment. Second, the refugees are motivated by pull and push factors at once as the authors discussed in the precedent section. Third, although adaptation to the Lebanese culture is easier, resilience is nevertheless needed due to the Lebanese Government’s policies, which forbid refugees to work in the country. Fourth, with regard to migration studies in general, this paper stands half way between the various studies conducted on ethnic entrepreneurship, immigrant entrepreneurship and refugees. Indeed, the authors brought together many concepts such as social bonds, social capital, culture, political environment, and the service industry. On the managerial level, the findings allow the institutions and the government to target those refugees who show an appetence to entrepreneurship to stimulate their action, shortly after arriving in Lebanon, as their entrepreneurial intent decreases with the time they spend, often unemployed, in the host country. Should government policy change, both the integration of refugees, and entrepreneurship in general would benefit.

This paper examines the relationship between boards of directors' demographic diversity and firms' financial performance. In particular, we highlight how women and ethnic minorities can affect Middle Eastern SMEs' financial performance. Using an unbalanced panel of 1,855 firm-year observations of 371 boards of directors from nine Middle Eastern countries, our results support the positive impact of women and ethnic minority group members on Middle Eastern firms' performance. However, our evidence implies that when Western ethnic minority members increase, firms' performances tend to decrease, because these board members are appointed for regional and international board reputation legitimacy, personal business agendas, and links to the external corporate environment.

Purpose The purpose of this study is to examine the influence of culturally endorsed implicit leadership theories (CLTs), specifically the cultural assumptions regarding ideal leadership, on individual entrepreneurship within the context of Lebanese culture. This paper investigates the relationship between culture and entrepreneurship by incorporating cultural values such as uncertainty avoidance and in-group collectivism, cultural practices and two types of CLTs: self-protective and charismatic. By exploring these factors, this study aims to gain a deeper understanding of the role of culture in shaping entrepreneurial behavior. Design/methodology/approach As a fundamental quantitative research, this study used a snowball sampling method to collect primary data from 118 Lebanese entrepreneurs, avoiding selection biases. Three models were used, relevant to nascent entrepreneurship, new entrepreneurship and old entrepreneurship, and the data was analyzed using logistic regression analysis and likelihood ratio tests. Findings The findings indicate that there is a correlation between CLTs, cultural values and practices and individual entrepreneurship. However, this study did not find evidence of a causal relationship between cultural values and individual entrepreneurship through the mediating role of self-protective and charismatic CLTs. Practical implications The research findings shed light on the beneficial synergy between cultural leadership ideals and individual entrepreneurship in the Lebanese context, providing a closer and more productive approach to studying entrepreneurship and leadership. From a managerial standpoint, these results have important implications for promoting entrepreneurship among various stakeholders, including educators, policymakers and support organizations. Originality/value This study differs from previous research by examining a country that demonstrates high levels of entrepreneurial awareness and involvement despite its unstable political and economic conditions.

Purpose The purpose of this study is to examine determinants of profitability of non-financial firms listed small- and medium-sized enterprises (SMEs) in the UK from 2012 till 2020. It has been argued that profitability plays a key role in economic development and growth. Despite the important role that SMEs play in developed economies like UK, academic research into SMEs profitability determinants in developed countries is not extensive. Design/methodology/approach The methodologies used include dynamic panel data estimation techniques. Relationship of nine independent variables with profitability was examined. Two models are created using return on assets (ROA) and return on equity (ROE) as dependent variables. Size, age, efficiency, working capital, liquidity, leverage and volatility of the firm represent firm-specific independent variables. Two macroeconomic variables, namely, gross domestic product and inflation are also used as independent variables. Data obtained from Thomson Reuters Data Stream for 93 listed SMEs companies in the UK from 2012 to 2020. Fixed effects, random effects and generalized method of moments were used in data analysis. Findings All variables showed significant influence on profitability, except liquidity reflecting insignificant impact on profitability in two regression models conducted for 93 firms under study. Efficiency, liquidity and leverage are the only three independent variables with similar impact on both ROA and ROE. Practical implications Identifying determinants of profitability will help stakeholders and corporate executive make sound decisions to ensure sustainability and stability at the firm level. This is particularly important given the key role played by SMEs in economic development and growth. The findings of this study would help direct financial management practices to ensure a favorable sustainable organizational performance. Originality/value This study differs from previous studies that focused mainly on developing countries; with limited research conducted on profitability of SMEs in developed economies. To the best of the author’s knowledge, this is the first study to examine factors influencing profitability of SMEs in UK. Previous studies concentrated on service sector like insurance and hotel firms.

Purpose This study focuses on exploring charismatic leadership within Lebanese Information Technology (IT) small and medium-sized enterprises (SMEs) and its influence on productivity. Through an in-depth analysis of the charismatic qualities and behaviors exhibited by leaders in these organizations, this research aims to delineate how such attributes may shape productivity levels. This study aims to deepen our understanding of leadership dynamics within the context of Lebanese IT SMEs, providing essential insights that can contribute to the enhancement of organizational performance and success. Design/methodology/approach This fundamental research used a quantitative approach and a purposive sampling method to select 342 Lebanese IT SMEs for primary data collection through a survey. Statistical regression analysis was then applied to treat the collected data. Findings The findings of this study reveal a positive correlation between charismatic leadership and increased innovation behavior among group or board members. This correlation can be strengthened by fostering a sense of ownership toward innovation and by ensuring a healthy work-life balance. Furthermore, the creation of an environment that emphasizes open communication and trust can enhance this correlation. Practical implications The implications of these findings are significant for organizations seeking to enhance their innovation capabilities. They suggest that investing in the development of charismatic leadership skills can be a valuable strategy for fostering innovation and creativity. Originality/value This study offers a unique and practical assessment of the role that charismatic leadership plays in maintaining resilient firm structures, especially during periods of political and economic instability.

Purpose This study aims to explore the political dimension of social network theory and assess how these connections motivate entrepreneurial activity and enhance postentry stages. The authors take an individualistic approach to the topic of institutional deterioration by uncovering the potential opportunities it can create, as entrepreneurship often arises when a market opportunity is perceived. Design/methodology/approach This study used a quantitative approach, using a self-selection sampling method to target private entities that own electric generators (also known as “illicit SMEs”) who are providing electricity services to the community despite the deterioration of the public energy sector in Lebanon. Data was collected through a survey administered electronically to 230 illicit SMEs, using a judgmental sampling method to ensure representation from all Lebanese governorates. The collected data was analyzed using ordinal least squares regression models. Findings The findings indicate a significant relationship between institutional deterioration and the reinvestment rate of entrepreneurs, with the moderating effect of political connections suggesting that the impact of institutional deterioration is dependent on the strength of an entrepreneur’s political connections. Practical implications The research findings demonstrate the significant influence of social ties and political connections on entrepreneurial activities, particularly in the context of SMEs that are providing services “illegally”. These results shed light on the importance of considering the role of social and political factors in the success and sustainability of entrepreneurial ventures operating in challenging environments. Originality/value Entrepreneurial studies typically focus on free market platforms and supply-demand associations, assuming perfect government conditions. However, this study differs from previous research by highlighting the positive impact of social ties on entrepreneurial market access within a socially linked environment. The findings suggest the importance of considering social connections in entrepreneurial studies, particularly in challenging economic and political contexts.
