Unlike conventional aircraft, birds can glide without a vertical tail. The purpose of this paper is to analyse the influence of dihedral angle spanwise distribution on lateral-directional dynamic stability by the simulation, calculation in the development of the bird-inspired aircraft and the flight testing.

The gliding magnificent frigatebird (Fregata magnificens) was selected as the study object. The geometric and mass model of the study object were developed. Stability derivatives and moments of inertia were obtained. The lateral-directional stability was assessed under different spanwise distributions of dihedral angle. A bird-inspired aircraft was developed, and a flight test was carried out to verify the analysed results.

The results show that spanwise distribution changing of dihedral angle has influence on the lateral-directional mode stability. All of the analysed configurations have convergent Dutch roll mode and rolling mode. The key role of dihedral angle changing is to achieve a convergent spiral mode. Flight test results show that the bird-inspired aircraft has a well-convergent Dutch roll mode.

The theory that birds can achieve its lateral-directional stability by changing its dihedral angle spanwise distribution may explain the stability mechanism of gliding birds.

This paper helps to improve the understanding of bird gliding stability mechanism and provides bio-inspired solutions in aircraft designing.

The purpose of this paper is to answer the following research question: how can intermediaries contribute to social impact creation through their interventions at different levels of distribution networks in the base of the pyramid (BoP) markets?

The paper adopts an embedded case study of an intermediary organization. The analysis focuses on the intervention of the intermediary on the distribution stages of supply chains in four different projects in the food sector in Ethiopia, Benin, Nigeria and Bangladesh.

The embedded case study reveals essential formal and informal roles undertaken by the intermediary organization to develop decentralized distribution networks based on local micro-entrepreneurs. The study proposes that efforts undertaken by the intermediaries toward knowledge sharing and capacity building among partners can enable the adoption of pro-poor strategies across the supply chain. Moreover, hybrid intermediaries can act as “guardians” of the mutual value creation approach since one of their key roles is to advocate the needs of the BoP.

Important implications for improving nutrition and food security in the BoP markets are developed based on the empirical findings. The findings open avenues for further research into the antecedents of retention rates in distribution networks based on local micro-entrepreneurs.

Findings have implications for different types of BoP initiatives by highlighting how intermediary organizations intervene to develop distribution models with a special focus on social impact.

This paper fills an important research gap by discussing social impact aspects in BoP supply chains by adopting the perspective of intermediary organizations.

A major part of knowledge management for knowledge-intensive firms such as professional service firms is the increasing focus on thought leadership. Despite being a well-known term, it is poorly defined and analysed in the academic and practitioner literature. The aim of this article is to answer three questions. First, what is thought leadership? Second, what tensions exist when seeking to create thought leadership in knowledge-based organisations? Third, what further research is needed about thought leadership? The authors call for cross-disciplinary and academic–practitioner approaches to understanding the field of thought leadership.

The authors review the academic and practitioner literature on thought leadership to provide a rich oversight of how it is defined and can be understood by separating inputs, creation processes and outcomes. The authors also draw on qualitative data from 12 in-depth interviews with senior leaders of professional service firms.

Through analysing and building on previous understandings of the concept, the authors redefine thought leadership as follows: “Knowledge from a trusted, eminent and authoritative source that is actionable and provides valuable solutions for stakeholders”. The authors find and explore nine tensions that developing thought leadership creates and propose a framework for understanding how to engage with thought leadership at the industry/macro, organisational/meso and individual/micro levels. The authors propose a research agenda based on testing propositions derived from new theories to explain thought leadership, including leadership, reducing risk, signalling quality and managing social networks, as well as examining the suggested ways to resolve different tensions.

To the best of the authors’ knowledge, they are the first to separate out thought leadership from its inputs, creation processes and outcomes. The authors show new organisational paradoxes within thought leadership and show how they can play out at different levels of analysis when implementing a thought leadership strategy. This work on thought leadership is set in a relatively under-explored context for knowledge management researchers, namely, knowledge-intensive professional service firms.

Dating is a meaningful occupation for many single people. The occupation of dating has transformed considerably in Ireland due to recent changes in Irish culture and the advent of online dating technology. The purpose of this study was to explore the complexities and intricacies of dating in an Irish context.

A qualitative research approach was used and data were collected using semi-structured interviews with ten heterosexual women (age 24‐34) living in urban areas of Ireland. Data were analysed using inductive thematic analysis (Braun and Clarke, 2006).

Dating did not fully resonate with their experience, but they did not have an alternative term. The form of dating was influenced by cultural, temporal, physical and virtual contexts. Beliefs about dating, fluctuating emotions and feelings of mortification because of the stigma of online dating created meaning for participants and influenced their use of strategies to improve resilience. While dating was not a preferred occupation for participants because of its arduous nature and fluctuations in emotion, it was seen as essential to fulfil the function of finding a romantic partner or partner in occupation. Connections between participant experiences and occupational science are discussed to address the lexicon of dating and the form, function and meaning of dating.

This study contributes to occupational science knowledge by revealing the occupational understandings of dating as an emerging and dynamic occupation in a rapidly changing culture of Ireland.

In this paper, the authors suggest that Central Americans can use entrepreneurship to solve economic uncertainty in their home country and that entrepreneurship can contribute to reducing the number of undocumented migrants to the USA.

The authors first illustrate the context of Central American illegal migration to the USA from a transitional entrepreneurship perspective, the authors address the economic drivers of illegal migration from Central America, which results in marginalization in the USA. Second, the authors build a theoretical model that suggests that Central Americans can improve their entrepreneurial abilities through the entrepreneurial cognitive adjustment mechanism.

Central Americans at risk of illegally migrating to the USA have high entrepreneurial aptitudes. Entrepreneurship can help them avoid the economic uncertainty that drives Central Americans to illegally migrate to the USA and become part of a marginalized community of undocumented immigrants. This conceptual paper introduces an entrepreneurial cognitive adjustment mechanism as a tool for Central Americans to reshape their personalities and increase their entrepreneurial abilities in their home countries. In particular, entrepreneurial intentions reshape the personality characteristics of individuals (in terms of high agreeableness and openness to experiences, as well as low neuroticism) through the entrepreneurial cognitive adjustment mechanism, which consists of reflective action in sensemaking, cognitive frameworks in pattern recognition and coping in positive affect.

This paper studies Central Americans at risk of illegal migration using the lens of transitional entrepreneurship, which advances the understanding of the antecedents to marginalized immigrant communities in the USA and suggests a possible solution for this phenomenon. Besides, the authors build a cognitive mechanism to facilitate the transitional process starting from entrepreneurial intention to reshaping individuals' personality, which further opens individuals' minds to entrepreneurial opportunities. Since entrepreneurial intention applies the same way to all entrepreneurs, the authors' aim of constructing the entrepreneurial intention unfolding process will go beyond transitional entrepreneurship and contribute to intention-action knowledge generation (Donaldson et al., 2021). Moreover, the conceptual study contributes to public policy such that international and local agencies can better utilize resources and implement long-term solutions to the drivers of illegal migration from Central America to the USA.

The purpose of this study is to analyze how institutional governance and business environment affect countries’ competitiveness and their relative importance.

In this paper, the authors analyze how institutional governance and business environment affect countries’ competitiveness, their relative importance and what are the implications for Brazil. The authors have collected data from 131 countries related to the institutional governance, business environment and competitiveness of these countries. For the analysis of the mentioned influences, the technique of partial least squares structural equations modeling is used.

Results indicate that the main role in countries’ competitiveness is played by the quality of institutional governance. The quality of the business environment reinforces the positive effect of the quality of institutional governance on countries’ competitiveness (mediation effect). Brazil has poor governance quality indicators when compared to high-middle income countries, especially regarding government effectiveness, political stability and control of corruption.

The study provides a better understanding of the relative importance of governance quality and business environment quality for countries’ competitiveness. One limitation of this study is that the research was restricted to data related to the year 2019.

For strategists and decision-makers, understanding these effects on countries’ competitiveness and their relative importance is fundamental to understanding what makes their companies internationally competitive.

The presence and appreciation of institutional governance quality need to be cultivated in society.

Instead of using the original diamond model, which presents circular relationships, the authors have used the business environment construct, composed of elements of the diamond model to test the relationships between the quality of institutional governance, competitiveness and the business environment.

In spite of ongoing and recent initiatives aimed at broadening participation in engineering, the representation of diverse groups of learners in engineering graduate programs in the USA remains a challenge. Foregrounding the voices of 26 Black male engineering faculty, this study aims to investigate how institutions might recruit and retain more Black men in engineering graduate programs.

For this study, inductive thematic analysis was used.

The authors show that three themes, namely, representation as an asset, invested mentors and faculty, and supportive peer networks described as the “Vibe” manifest as crucial elements for successful recruitment and retention of Black men in engineering graduate programs.

These findings are meant to augment the conversation around diversity, equity and inclusion in engineering graduate programs and to address a dearth of published research on the Black male engineering population. This work is also meant to help institutions conceptualize ways to create a “Vibe” that might be transferable to their institution’s sociocultural context.
