Bionic flapping-wing aerial vehicles (FWAVs) mimic natural flyers to generate the lift and thrust, such as birds, bats and insects. As an important component of the FWAVs, the flapping wings are crucial for the flight performance. The aim of this paper is to study the effects of different wings on aerodynamic performance.

Inspired by the wings structure of birds, the authors design four cambered wings to analyze the effect of airfoils on the FWAVs aerodynamic performance. The authors design the motor-driven mechanism of flapping wings, and realize the control of flapping frequency. Combined with the wind tunnel equipment, the authors build the FWAVs force test platform to test the static and dynamic aerodynamic performance of different flapping wings under the state variables of flapping frequency, wind speed and inclined angle.

The results show that the aerodynamic performance of flapping wing with a camber of 20 mm is the best. Compared with flat wing, the average lift can be improved by 59.5%.

Different from the traditional flat wing design of FWAVs, different cambered flapping wings are given in this paper. The influence of airfoils on aerodynamic performance of FWAVs is analyzed and the optimal flapping wing is obtained.

While entrepreneurship has long been heralded for its positive contributions, there is a growing recognition of its “dark side,” characterized by unproductive, unethical and destructive actions. This exploratory literature review aims to illuminate the underexplored dark side of entrepreneurship, thereby enriching the discourse on entrepreneurship’s dual nature.

This study employs a robust mixed-method approach, integrating phenomenologically detailed co-citation bibliographic coupling with detailed thematic data and code-weaving. Science mapping tools like R-Bibliometrix and VOSviewer enhance the credibility of the findings by providing a sophisticated and reproducible methodological framework.

This review defines dark entrepreneurship, its characteristics, and its complexities. We introduced the “Dark Entrepreneurship Trinity”: Ethical Complexity, Institutional Navigation and Conflict Entrepreneurialship, with Institutional Navigation as the apex theme. It elucidates how this theme influences ethical dilemmas and operational strategies in conflict zones, illustrated through a diagram depicting their complex interrelations and dynamics.

The originality of this literature review lies in its comprehensive synthesis of the dark side of entrepreneurship. This review significantly contributes to the academic discourse by delineating a clearer picture of the destructive potentials of entrepreneurship. It compiles existing research, critically addresses the gaps and suggests future pathways for empirical studies.

Despite being conjointly stronger in their synergies in the past, there is still a significant gap between management and organization studies and sociology. The temporal lag is also, on occasion, a substantive lag. The emergent sociological concept of emotional reflexivity has recently been used in organizational studies. The question that animates this contribution concerns the nature of this translation, reception, and extension; thus, we ask how organization studies have been using the sociological concept of emotional reflexivity? We will examine recent seminal sociological studies on emotional reflexivity to answer this inquiry and consider some organizational studies citing these. We describe the reception of sociological ideas of emotional reflexivity in management and organization studies literature. By analyzing the differences and disconnections produced within this discourse, it will be possible to understand that emotional reflexivity is rarely addressed in emotional encounters between people and other modes of being in modern organizations. We introduce narrative fiction as a method; the narrative focuses on the relationships between humans and other beings in the workplace dynamics of a vocational school. The story tells how Charlie, a deaf student, changed his life after entering the vocational school and becoming involved with different pedagogical teaching-learning strategies. Adopting two deaf dogs, which had both suffered from past unsuccessful adoption experiences, produced life-enhancing emotional reflexivity. We conclude with a research agenda scoping further directions.

This study examines the dynamic relationship between UK entrepreneurs' engagement with society and the economic climate surrounding the 2008 financial crisis – before, during and after it. We investigate whether such crises strengthen or weaken the connections between entrepreneurship and society, considering gender differences.

We employ individual-level data from the British Household Panel Survey (BHPS) and the UK Longitudinal Study (UKLS) to assess changes in entrepreneurs' social engagement during crises. We use panel logit and Poisson regressions to estimate trends in social engagement over time and in response to economic turmoil.

We discover that entrepreneurs are more likely to join social organisations during economic turmoil. This engagement varies by gender, with female entrepreneurs more inclined to engage with social organisations than males. This suggests that female entrepreneurs perceive crisis risks differently, seeking support to navigate uncertainty. Additionally, we find evidence supporting the idea that female entrepreneurs take longer to recover from major economic shocks than their male counterparts.

Entrepreneur behaviour during crises remains understudied. The role of social ties and networks in aiding entrepreneurs during systemic crises is particularly unexplored. This study addresses this gap, highlighting gender-based behavioural differences during crises and paving the way for further research. It represents a crucial step in integrating crisis literature into entrepreneurship studies.

The purpose of this paper is to investigate the factors influencing the development of social media marketing strategy in an international context. We specifically look at the potential drivers and barriers throughout the social media marketing strategy development process and how cultural differences shape social media marketing strategy decision-making among firms in international markets.

The study is conducted with an inductive research approach involving in-depth interviews with 32 firms from Finland, China and Brazil. Using inductive data analysis, we identify both internal and external factors that drive and hinder the development of firms’ social media marketing strategies. Moreover, we explore the essential elements in social media marketing strategy development based on the key practices observed among these firms, which enables us to conduct a comparative analysis of how cultural values influence the development of social media marketing strategies.

Our findings underscore the importance of both internal (i.e. resources and capabilities) and external (i.e. market-level and country-level) factors that influence the development of social media marketing strategy. Our analysis also unveiled four key practices throughout the social media marketing strategy development process: social selling, content marketing, risk management and relationship management. Additionally, we identified three distinct mindsets regarding firms’ social media selling objectives across companies in the three countries.

The comparative approach provides novel insight into firms' international social media marketing strategy. Our proposed conceptual model shows the development process of social media marketing strategy in the international context. The research propositions highlight the role of cultural values and open up new avenues for future research.
