The purpose of this paper is to construct an event-triggered finite-time fault-tolerant formation tracking controller, which can achieve a time-varying formation control for multiple unmanned aerial vehicles (UAVs) during actuator failures and external perturbations.

First, this study developed the formation tracking protocol for each follower using UAV formation members, defining the tracking inaccuracy of the UAV followers’ location. Subsequently, this study designed the multilayer event-triggered controller based on the backstepping method framework within finite time. Then, considering the actuator failures, and added self-adaptive thought for fault-tolerant control within finite time, the event-triggered closed-loop system is subsequently shown to be a finite-time stable system. Furthermore, the Zeno behavior is analyzed to prevent infinite triggering instances within a finite time. Finally, simulations are conducted with external disturbances and actuator failure conditions to demonstrate formation tracking controller performance.

It achieves improved performance in the presence of external disturbances and system failures. Combining limited-time adaptive control and event triggering improves system stability, increase robustness to disturbances and calculation efficiency. In addition, the designed formation tracking controller can effectively control the time-varying formation of the leader and followers to complete the task, and by adding a fixed-time observer, it can effectively compensate for external disturbances and improve formation control accuracy.

A formation-following controller is designed, which can handle both external disturbances and internal actuator failures during formation flight, and the proposed method can be applied to a variety of formation control scenarios and does not rely on a specific type of UAV or communication network.

Corporate Social Responsibility (CSR) reporting has been widely accepted as a vital tool for communicating with stakeholders on a range of social, environmental, and governance issues, but how companies define, interpret, apply, integrate, and communicate their CSR efforts and impacts in corporate reporting is anything but a straightforward task. The purpose of this chapter is to explore the concept of materiality in CSR reporting and demonstrate practical examples of good CSR and Sustainable Development Goals (SDGs) reporting practices. We chose the aviation industry because of its economic relevance, constant growth, and future expected changes in the aftermath of COVID-19. In addition, airlines affect many of the SDGs directly and indirectly with contending results. This chapter is timely because of the growing willingness by companies to integrate CSR and environmental, social, and governance (ESG) thinking into the corporate strategy and business operations using materiality assessment and enhancing their competitive advantage and ability to maintain long-term value and because ESG and ethical investing have become part of the mainstream investing. Thus, this chapter contributes to an understanding of the wide range of existing and new reporting frameworks and regulations and reinforces the importance of discussing how this diversity of approaches can affect the work toward worldwide comparability of CSR and sustainability reporting.

Audio-visual presentations – delivered either in real-life or virtually – feature heavily in educational assessments and employer recruitment. This study explored neurodivergent undergraduate students' experiences of presentations. The aim was to understand how neurodivergent students describe experiences of presentations in educational and workplace contexts and how neurodivergent students experienced training, support activities and learning technologies associated with presentations.

An exploratory qualitative phenomenological approach was taken, from students' perspectives. Overall, 12 neurodivergent undergraduate students (M_age = 21.89 years, SD_age = 2.57; nine women, two men, one non-binary) discussed their experiences of presentations within educational and/or professional contexts via semi-structured remote interviews. The sample included individuals with diagnoses of anxiety, depression, dyslexia, borderline personality disorder, dyscalculia, dyspraxia, and panic disorder.

Thematic Analysis of interview transcript data revealed four main themes (with sub-themes in parentheses): Control (preparedness; delivery); Audience Perceptions and Behaviours (expectations of “normality”; shared knowledge; audience “expertise”); Intervention Efficacy (early access; individuality; learning technologies) and Value of Presentation Skills (reciprocity between education – workplace; self-efficacy; self-esteem; learner development).

The dataset was extracted from a relatively small sample from a single university and indeed a single academic discipline. Furthermore, the dataset was collected during the ongoing COVID-19 pandemic – although this gives us a valuable snapshot of students' experiences and perceptions during this time, whether the author can extrapolate these findings in future is unclear.

The findings help understand how we better support students. Better ways to support learners can be developed in developing presentation and audience skills. This research shows that alternative assessment provisions must be based on individuals and their own specific needs and skills, rather than their divergence label. This research can inform the development of digital learning technologies.

This research can inform how educators, coaches, trainers, and facilitators “train” audiences to be more inclusive and less prejudicial/biased. We can understand how to better construct social spaces for presentations, in the classroom and the world of work.

This report presents a valid and valuable methodological approach, conducted and reported transparently. This research was conducted during a crucial, unprecedented and precarious time period for learners and education professionals. Implications are considered with respect to the design of teaching, learning and assessment activities; facilitator, learner, and peer behaviours; the role of digital learning technologies; and employment/employability.

This chapter provides an overview of the century-long economic history of scheduled passenger airlines services in developing countries. Initially there is discussion of what constitutes a developing country and how airlines activities interact with development processes. It is a broad view which compares and contrasts the varying paths civil aviation has taken within different countries and internationally. It offers some insights as to why airlines are where we are today and as to what the future may hold for developing nations.

This study aims to describe and evaluate various visual and creative tools for supporting the in-depth biographical interview aimed at analyzing educational communities and their stakeholders.

Researching educational spaces today requires new ways of understanding, analyzing and studying. The complex characteristics, functions and realities demand research that responds to educational singularities. It is a matter of deeply understanding the educational phenomenon's peculiarities. For these purposes, instruments and research paradigms are needed to extract data and reach information saturation regarding the data obtained from the proposed objects of study. With this in mind, the following paper suggests reflecting on data collection tools that can complement the interview and biographical-narrative research approach. The authors highlight the use of photo-elucidation, the biogram-based timeline, the organigram and the flight of the geese, all of which are instruments endowed with a visual character that allows a deeper understanding of the object studied.

The main contribution of this paper is to unpack the uses and applications of four visual tools that support the interview technique. First, photo-elucidation is presented as a sensory strategy to stimulate the narrative during the dialogical exchange of the interview. Next, the timeline is described as a visual concretization of the traditional biogram widely used in educational research. Next, the authors unravel the uses of the organizational chart in educational research, which, due to its nature and utility, provides a glimpse of the organizational functioning of an institution and is particularly suitable for research in institutional frameworks. Finally, the tool known as the flight of the geese is presented. This tool is recommended for use in educational leadership and teamwork studies due to its simplicity and high representativeness of the hierarchy of roles and functions.

Health risks associated with coronavirus disease 2019 (COVID-19) have severely affected the financial stability of airline companies globally. Recapturing financial stability following this crisis depends heavily on these companies’ ability to attain efficient and productive operations. This study uses several empirical approaches to examine key factors contributing to carriers sustaining high productivity prior to, during and after a major recession. Findings suggest, regardless of economic conditions, that social distancing which requires airline companies in the Asia Pacific region to fly with a significant percentage of unfilled seats weakens the performance of those companies. Furthermore, efficient operations do not guarantee the avoidance of productivity declines, especially during a recession.

The expected learning outcomes are to understand the complexities involved in the integration of two carriers with different business strategies and approaches, the merger of two brands with distinct personas and identities and the confluence of two different cultures; figure out the strategic options in front of the Tata Group and how it can deal with various macro- and micro-level business challenges, defy the financial hiccups and manoeuvre the operational complexities to accomplish mission Vihaan.AI; and develop a pragmatic approach to macro and micro business environmental scanning for making strategic business decisions.

In November 2022, Tata Group, the salt to software conglomerate, announced the merger of Air India (AI) and Vistara. This would lead to the formation of the full-service airline under the brand name “Air India”. The obvious reason behind this was the higher recognition, salience and recall of the brand AI as compared with Vistara in the global market. The Tata Group envisaged the brand AI to be a significant international aviation player with the heritage, persona and ethos of the brand Vistara in the renewed manifestation of AI. To realise these goals, Tata Group laid down an ambitious plan called “Vihaan.AI”, which was aimed at capturing a domestic market share of 30% by 2027.

This study presents a systematic literature review (SLR) of the interdisciplinary literature on drones in last-mile delivery (LMD) to extrapolate pertinent insights from and into the logistics management field.

Rooting their analytical categories in the LMD literature, the authors performed a deductive, theory refinement SLR on 307 interdisciplinary journal articles published during 2015–2022 to integrate this emergent phenomenon into the field.

The authors derived the potentials, challenges and solutions of drone deliveries in relation to 12 LMD criteria dispersed across four stakeholder groups: senders, receivers, regulators and societies. Relationships between these criteria were also identified.

This review contributes to logistics management by offering a current, nuanced and multifaceted discussion of drones' potential to improve the LMD process together with the challenges and solutions involved.

The authors provide logistics managers with a holistic roadmap to help them make informed decisions about adopting drones in their delivery systems. Regulators and society members also gain insights into the prospects, requirements and repercussions of drone deliveries.

This is one of the first SLRs on drone applications in LMD from a logistics management perspective.

In recent years, fire accidents in engineering structures have often been reported worldwide, leading to a severe risk to life and property safety. The present study is carried out to evaluate the performance of Ground Granulated Blast Furnace Slag (GGBS) and fly ash–blended laterized mortars at elevated temperatures.

This test program includes the replacement of natural river sand with lateritic fine aggregates (lateritic FA) in terms of 0, 50 and 100%. Also, the ordinary Portland cement (OPC) was replaced with fly ash and GGBS in terms of 10, 20, 30% and 20, 40 and 60%, respectively, for producing blended mortars.

This paper presents results related to the determination of residual compressive strengths of lateritic fine aggregates-based cement mortars with part replacement of cement by fly ash and GGBS exposed to elevated temperatures. The effect of elevated temperatures on the physical and mechanical properties was evaluated with the help of microstructure studies and the quantification of hydration products.

A sustainable cement mortar was produced by replacing natural river sand with lateritic fine aggregates. The thermal strength deterioration features were assessed by exposing the control specimens and lateritic fine aggregates-based cement mortars to elevated temperatures. Changes in the mechanical properties were evaluated through a quantitative microstructure study using scanning electron microscopy (SEM) images. The phase change of hydration products after exposure to elevated temperatures was qualitatively analyzed by greyscale thresholding of SEM images using Image J software.

The paper aims to examine literature on the issues of the pilot shortage in the United States Air Force and the demographic diversity dilemma within the United States Air Force pilot community and how it relates to the National Defense Strategy. In addition, there is an examination of current initiatives designed to combat these issues.

The paper opted for an exploratory review of 90 sources from 2012 to 2023 to examine the pilot shortage and pilot diversity issues within the United States Air Force. Three theories, the theory of generative interactions, the theory of cognitive diversity and the identity theory, were examined in relation to the barriers to the pilot diversity issue.

The paper provides emergent insights from the literature into the growing pilot shortage and diversity disparity found within the United States Air Force pilot community. These issues were associated with many barriers, including geographic disparity, socioeconomic status, culture, education, mentorship and life balance.

The current initiatives examined are new and, as such, warrant future research. In particular, what are the long-term projections for the youth flight programs? An examination of the effectiveness of improving the pilot shortage and pilot diversity within the Air Force should be further scrutinized in the coming years as new cadets enter pilot training after accession.

This paper highlights a need to further study the effectiveness of youth flight programs and other United States Air Force initiatives in improving pilot numbers and diversity.
