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.

This paper aims to explore the biodiversity and threatened species extinction reporting of 54 biodiversity-indexed companies on the Indonesia Stock Exchange (IDX). The primary objectives are to explore the rhetoric of biodiversity disclosure as a practice of virtue ethics and to identify instances of emancipatory extinction accounts on the International Union for Conservation of Nature (IUCN) Red List.

The research sample comprised 54 biodiversity-indexed companies on the IDX. A content analysis of the narrative text of their annual and sustainability reports for 2020 was conducted to discern the rhetoric of biodiversity disclosure as an ethical practice using Aristotle’s rhetoric (ethos, logos and pathos). The identification of extinction accounts listed on the IUCN Red List was conducted based on criteria established in the conceptual framework of Atkins and Maroun (2018).

All 54 companies used ethos, logos and pathos in their biodiversity disclosure as a virtuous practice. These disclosures improve the tone of corporate communications and enhance accountability and transparency. Low-profile companies showed a greater propensity for reporting biodiversity disclosures compared to high-profile companies. Additionally, the authors identified 14 companies informing extinction accounts that qualify as emancipatory accounts, with high-profile companies disclosing extinction more frequently than low-profile ones. Emancipatory accounting highlighted species such as turtles, orangutans, elephants, rhinos, turtles and medicinal plants. These accounts are intended as a form of accountability to the species.

The limitation of this research is the observation of annual reports in one period. Future studies can add more observation periods to see the consistency of companies in disclosing biodiversity and extinction.

Companies can adopt the rhetorical strategy of ethos, logos and pathos in disclosing their biodiversity. For policymakers, it is important to establish regulations to encourage companies to disclose biodiversity. The implications for accountants, to contribute more to biodiversity and extinction reporting, considering that previously sustainability accounting reporting was mostly carried out by nonaccountants.

Regarding social implications, emancipatory accounts aimed at preventing the extinction of animals such as birds, orangutans and rhinos will have significant social and natural impacts.

This research represents the first use of Aristotelian rhetoric and virtue to understand biodiversity disclosure as virtue rhetoric and extinction disclosure as emancipatory accounting. This rhetoric is a benevolent persuasion tool that can shape the audience’s thinking and behavior in a more ethical manner concerning biodiversity issues. It provides evidence of the role of accounting as a social and moral practice, which is particularly relevant in the face of a complex reality and increasing concerns, notably regarding the threat of biodiversity loss and extinction.

This paper brings attention to the role of hybrid middle managers. In particular it explores the relationship of organisational purpose and role requirements.

The primary research question for the original research was: What does it mean to hybrid managers to lead and deal with imposed changes (restructuring) to services? A novel narrative approach based on a synthesis of Czarniawska, Gabriel and Boje was applied. Accounts from interviews were condensed into narratives by initially using the categories defined by Gabriel (2000) as epic, tragic, comic and romantic and then further categorised into stories, themes and a serial (Czarniawska, 1997). The final stage of the three-way synthesised narrative approach incorporated Boje’s (2001) notion of “antenarrative” to include pre-emplotment elements.

Four narratives are provided that give insight to the nature of the struggles the hybrid middle managers were in the midst of. A struggle to address incongruent demands being placed on them that cause tension with their sense of purpose, organisational goals and their hybrid clinical roles and management roles. In the midst of these struggles the narratives illustrate the dynamic of ethical resistance that seeks a way forward. However, this appears to come at a health and well-being cost to the middle managers.

The paper offers up the notion of an added third bind to the traditional double, that of “ethical resistance”, a struggle to align organisational purpose with clinical and management role requirements. Theorising this third bind provides a new insight into understanding the context and dynamics of the hybrid middle manager role and behaviour. Indeed, the idea of ethical resistance may cause a revision of how resistance is understood.

The corona virus outbreak has affected the entrepreneurial ecosystem adversely. This in particular has impacted on females. This study aims to identify the factors affecting the entrepreneurial intention (EI) of females under post-COVID adverse conditions.

A total of 340 articles were screened applying the preferred reporting items for systematic reviews and meta-analyses method. The EI of individuals undertaking different professional courses from three top National Institute Ranking Framework (NIRF) government institutes were then analyzed. In the expert analysis, the nominal group technique (NGT) and analytic hierarchy process (AHP) were used to identify and rank the crucial factors. Subsequently, in the exploratory analysis, a 19-item questionnaire was framed. The data was analyzed using SmartPLS 3.

Resilience, entrepreneurial education, self-concept and self-efficacy, social influence and opportunity perception were identified as critical indicators. Resilience was identified as the most significant factor. The partial least square structural equation modeling (PLS-SEM) revealed that all the factors except social influence had significant effect on the EI of females.

This study focuses primarily on factors affecting females in India. As ecosystems and support vary by region and country, the authors suggest that this study be replicated in different regions/countries in the future.

The potential entrepreneurs can use this study's reference to identify the abilities they need. The government and academic institutions can have skill/training programs to enhance the effect of important factors identified in the study.

While there is growing research of entrepreneurship and entrepreneurial marketing post-pandemic, there are a lack of Indian studies and female entrepreneurship studies.

The aim of this paper is to review the psychological literature on curiosity and its relationship to information-seeking behaviour, and compare this with the information science literature on the same subject.

The approach adopted is that of a comparative literature review, with an analysis of the papers retrieved in terms of their theoretical approach, context, study population and research method.

Curiosity is understood as a multi-faceted cognitive trait in humans and the relationship to information-seeking behaviour is explored through an exploration of other personality characteristics. There is very little citation of the information science literature in the psychological papers, and only a little more citation of the psychological literature in the information science papers.

The author is not aware of any similar exploration of the literature on curiosity.

This paper aims to create a comprehensive framework for selecting alternative materials in construction projects, integrating building information modeling (BIM) and the particle swarm optimization (PSO) algorithm. Materials comprise 60%–65% of the total project cost, and current methods require significant time and human resources.

A prototype framework is developed that considers multiple criteria to optimize the material selection process, addressing the significant investment of time and resources required in current methods. The study uses surveys and interviews with construction professionals to collect primary data on alternative materials selection.

The results show that integrating BIM and the PSO algorithm improves cost optimization and material selection outcomes.

This comprehensive tool enhances decision-making capabilities and resource utilization, improving project outcomes and resource utilization. It offers a systematic approach to evaluating and selecting materials, making it a valuable resource for construction professionals.

This chapter examines the Netherlands’ challenges in safeguarding its low-lying coastline against rising sea levels and the consequences of coastal defense strategies on marine life, particularly in relation to SDG14. Sea-level rise necessitates increased soft coastal defense strategies, affecting seafloor areas and marine biodiversity through sand extraction and sand nourishments. The use of hard structures for coastal defense contributes to the loss of natural coastal habitats, raising biodiversity concerns. The chapter explores the potential benefits of artificial hard surfaces as marine habitats, emphasising the need for careful design to prevent ecological problems caused by invasive species. Strategies for enhancing biodiversity on human-made hard substrate structures, including material variations, hole drilling, and adaptations, are discussed. The ecological impact of marine sand extraction is examined, detailing its effects on benthic fauna, sediment characteristics, primary production, and fish and shrimp populations. Solutions proposed include improved design for mining areas, ecosystem-based rules for extraction sites, and ecologically enriched extraction areas. The ecosystem effects of marine sand nourishments are also analysed, considering the impact on habitat suitability for various species. The chemical effects of anaerobic sediment and recovery challenges are addressed. Mitigation measures, such as strategic nourishment location and timing, adherence to local morphology, and technical solutions, are suggested. The chapter underscores the importance of education in Nature-based Solutions and announces the launch of a new BSc programme in Marine Sciences at Wageningen University & Research, integrating social and ecological knowledge to address challenges in seas, oceans, and coastal regions and support SDG14 goals.

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.

Urban air mobility (UAM) development and deployment into future cities is gaining increasing and relevant interest in the past years. This study, a conceptual paper, aims to report the high-level description of the most relevant UAM application use cases (UCs) emerging from the research activities carried out in the ASSURED UAM project.

The UAM application UCs have been obtained from the ASSURED UAM project dedicated activities that have been carried out to, first, develop suitable operational concepts for UAM deployment in the next decades and, then, to further refine and design the most relevant UCs for UAM deployment in the next decades, leading to the public issue of dedicated overall document.

The ASSURED UAM UCs for UAM deployment in the next decades encompass both public (point-to-point, point-to-everywhere, direct medical transport of people) and private (direct last-mile delivery, advanced last-mile delivery, automatic personal aerial transportation) services applications, evolving in incremental way over time according to three considered time horizons (2025, 2030 and 2035), toward progressive integration into metropolitan transport system.

This paper provides final outline of the ASSURED UAM UCs, starting from the analysis of overall identified possible UAM applications, focusing on the description of the six main UCs considered as relevant for the application under the wider societal benefits point of view. The UCs are described in terms of expected operational environment, needed technological enablers and envisaged regulatory implications.
