Abstract
Purpose
Bezier curves are widely used in computer-aided geometric design (CAGD) for modeling objects such as aircraft, cars and ships. Augmented reality applications are an important type of new-generation technology that is increasingly being used in simulations in education, military fields and gaming fields. Our study aims to provide a different approach with Augmented reality applications, one of the new generation technologies, by examining some geometric properties of Bezier curves, which have an important place in the design world. In our study, the Bishop frame, curvatures, derivative formulas and the Darboux vector of the Bishop frame have been computed by the algorithm method for the whole points of the rational Bezier curves. In the last part, some numerical examples and augmented reality applications have been given for the rational and polynomial Bezier curves in the GeoGebra program. Firstly, geometric computations related to rational Bezier curves were made in the GeoGebra program, and then drawing algorithms of rational Bezier curves were demonstrated with videos in the GeoGebra Ar program.
Design/methodology/approach
In this study, the theoretical method used is the algorithmic computation of the Bishop frame of Rational Bezier curves. The design application involved creating some three-dimensional Bezier curve and their augmented reality application.
Findings
Using the algorithmic method, the Bishop frame of Rational Bezier curves was calculated, the curvatures of the curve's Bishop frame were determined and various properties were computed.
Originality/value
The originality of this study lies in the algorithmic computation of the Bishop frame of rational Bezier curves, which has not been previously addressed in the literature, as well as the calculation of certain properties related to the curvatures of the Bishop frame. Additionally, a boat design was created using Bezier curves, which are widely used in object design, and an augmented reality application was implemented. Another advantage of this study is that it is expected to help in the more effective use of Bezier curves in the gaming industry.

Abstract
Purpose
Immigration-themed children’s literature can be an important resource in the classroom, especially because some U.S. immigrant groups, including French-Canadians, have received limited curricular representation. Using the qualitative method of critical content analysis, this study aims to examine depictions of French-Canadian immigrants to the United States in contemporary children’s books.
Design/methodology/approach
Postcolonialism is employed as an analytical lens with special attention given to the ways immigrant characters are constructed as different from the dominant group (i.e., othering), how dominant group values are imposed on immigrant characters, and how immigrant characters resist othering and domination. Three books comprise the sample: “Charlotte Bakeman Has Her Say” by Mary Finger and illustrated by Kimberly Batti, “Other Bells for Us to Ring” by Robert Cormier, and “Red River Girl” by Norma Sommerdorf.
Findings
The findings reveal multiple instances in which French-Canadian immigrants are constructed as Other and few instances in which these characters resist this positioning, and these books reflect the real ways French-Canadians were perceived as subalterns during the mass migration from Québec to the United States between the late 19th and early 20th centuries.
Originality/value
This study is significant because it examines portrayals of a substantial immigrant group that has been overlooked in the immigration history curriculum. This sample of children’s books may be used to teach children the complexities of immigration history and provide a more nuanced understanding of immigration during the 19th and 20th centuries.

Abstract
Purpose
The purpose of this article is to report on a university’s internally funded research that was set up to examine the success of assessing learning within inclusion strategies across business studies courses. It also presents the responses that were needed and highlighted as a result of the disruption to students’ learning by the impact of coronavirus (COVID-19).
Design/methodology/approach
Within the social mobility model of disability, people are disabled by the barriers they face, not their impairment. A multi-method, qualitative approach was undertaken, with our discussion framed from within a reflective critical, conceptualised and sociological perspective.
Findings
While the findings revealed how the researched university had made considerable progress in many aspects of its inclusion strategies, the research also revealed some further barriers to inclusion. Some of the barriers were shown to be “cracks in the digital curriculum” that affected not just disabled but all students, whereby students were unintentionally excluded. In this article, we report on how the university had responded to students’ requests, and through a series of small steps, we discuss the positive impact of these actions. Although the changes instigated did help to improve inclusion, the small steps taken also highlighted the need for much more work to be undertaken on the journey to a fully inclusive university. The recent impact of the COVID-19 pandemic forced and/or accelerated the implementation of digital learning. This, in turn, instigated a rise in the awareness of mental illness and the effects of social isolation, which is now much higher than pre-COVID-19.
Research limitations/implications
The main limitation of the study was that the sample was small; however, the in-depth qualitative approach showed how the issues that had been problematic had been resolved and illuminated the further areas for future research.
Practical implications
The research reported here presents the practical steps that were taken in response to the students’ inclusion requests. The students’ requests were addressed, where practical and/or possible, for students to have assessment choice, further support from the well-being team and a further strengthening of local partnerships with the National Health Service and local charities.
Social implications
The research supports inclusion initiatives in higher education and society.
Originality/value
This study strengthens and/or builds upon the existing literature on the impact of COVID-19 on the teaching and learning of all students, and specifically those with invisible disabilities, by presenting the small steps in changes to the curriculum that can improve inclusion practices.

Abstract
This study proposes the factors influencing career commitment among public servants in Vietnam. By applying perspectives of the investment model with the moderating effects of perceived economic conditions, this study suggests that commitment to a career of public servants depends on career satisfaction, career alternatives, career investment, and professional self-efficacy. Additionally, the study proposes that perceived economic conditions moderate the relationships between these factors and career commitment. As economic instability may influence job satisfaction, turnover intentions, and investment decisions, understanding its interaction with career dynamics is crucial for public sector management. Overall, this study contributes to a better understanding of the complexities of career commitment among Vietnamese public servants and provides policymakers with more insights on how to improve employee commitment.

Abstract
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.

Abstract
Purpose
This study aims to identify the political alignment and political activity of the 11 Presidents of Britain’s most important scientific organisation, the Royal Society of London, in its early years 1662–1703, to determine whether or not the institution was politically aligned.
Design/methodology/approach
There is almost no information addressing the political alignment of the Royal Society or its Presidents available in the institution’s archives, or in the writings of historians specialising in its administration. Even reliable biographical sources, such as the Oxford Dictionary of National Biography provide very limited information. However, as 10 Presidents were elected Member of Parliament (MP), The History of Parliament: British Political, Social and Local History provides a wealth of accurate, in-depth data, revealing the alignment of both.
Findings
All Presidents held senior government offices, the first was a Royalist aristocrat; of the remaining 10, 8 were Royalist or Tory MPs, 2 of whom were falsely imprisoned by the House of Commons, 2 were Whig MPs, while 4 were elevated to the Lords. The institution was Royalist aligned 1662–1680, Tory aligned 1680–1695 and Whig aligned 1695–1703, which reflects changes in Parliament and State.
Originality/value
This study establishes that the early Royal Society was not an apolitical institution and that the political alignment of Presidents and institution continued in later eras. Furthermore, it demonstrates how the election or appointment of an organisation’s most senior officer can be used to signal its political alignment with government and other organisations to serve various ends.
