This paper focuses on the application of a robotic technique for modeling a three-wheeled mobile robot (WMR), considering it as a multibody polyarticulated system. Then the dynamic behavior of the developed model is verified using a physical model obtained by Simscape Multibody.

Firstly, a geometric model is developed using the modified Denavit–Hartenberg method. Then the dynamic model is derived using the algorithm of Newton–Euler. The developed model is performed for a three-wheeled differentially driven robot, which incorporates the slippage of wheels by including the Kiencke tire model to take into account the interaction of wheels with the ground. For the physical model, the mobile robot is designed using Solidworks. Then it is exported to Matlab using Simscape Multibody. The control of the WMR for both models is realized using Matlab/Simulink and aims to ensure efficient tracking of the desired trajectory.

Simulation results show a good similarity between the two models and verify both longitudinal and lateral behaviors of the WMR. This demonstrates the effectiveness of the developed model using the robotic approach and proves that it is sufficiently precise for the design of control schemes.

The motivation to adopt this robotic approach compared to conventional methods is the fact that it makes it possible to obtain models with a reduced number of operations. Furthermore, it allows the facility of implementation by numerical or symbolical programming. This work serves as a reference link for extending this methodology to other types of mobile robots.

The primary objective of this study is to analyze the performance and risk characteristics of portfolios composed of Spanish family businesses (FBs) when sustainability and quality factors are taken into account. By comparing different portfolio compositions against a benchmark, the study aims to provide insights into the impact of these factors on portfolio performance.

This study employs an empirical approach to evaluate the performance and risk of portfolios consisting of Spanish family businesses (FBs) by incorporating sustainability and quality factors. It compares the results of various portfolios against a benchmark, utilizing GARCH models and the extended six-factor model of Fama and French for the period 2018–2023.

The findings reveal that investing in Spanish family businesses (FBs) yields higher returns compared to the index, with portfolios incorporating quality factors demonstrating superior performance. However, the inclusion of sustainability factors negatively affects portfolio performance. These results highlight the significance of considering sustainability and quality factors in portfolio construction and investment decisions.

This study contributes to the existing literature by examining the performance and risk implications of incorporating sustainability and quality factors into portfolios of family businesses. The findings offer valuable insights for investors and managers interested in constructing portfolios or developing financial products that balance risk and return effectively.

For decades, the construction industry has not significantly changed the way it operates, despite its economic and ecological importance worldwide. Hilti’s ambition is to change that and create a better future for its customers. This chapter highlights which trade-offs Hilti faces in their innovation journey towards solutions, while transforming the organisation: speed versus involvement, agility versus perfection and relationship versus competencies. Visible leadership and the preservation of the unique Hilti culture has been critical to deal with those dualities. To create tangible results, it has proven essential to evolve structures and processes for the ‘new solution’ businesses, while changing the way of hiring people and the types of people required for those new units. Innovating the ‘Hilti way’ summarises key learnings for other organisations.

Nicolas Dupont, the owner of Chateau de Montana, a struggling (and old) boutique hotel in Crans-Montana Ski Resort, Switzerland, wished to renovate and reposition his family-owned hotel to target higher room rates. Dupont commissioned Olga Mitireva and Yulia Belopilskaya as consultants to assess the proposition. The consultants had to extract cues for the room rate of the repositioned hotel from comparable hotels. However, the room rates varied significantly across similar hotels due to their differing characteristics and locations. It was a cognitive challenge to read the patterns from a few comparable hotels. They collected the data of 200 hotels from similar locations and simulated room prices using hedonic regression models.

After reading and analysing the case study, the students would be able to distinguish the leadership styles based on leaders’ traits and behaviours, argue the importance of trust in leader–follower relationships thanks to the real-life examples presented and defend their side on the debate of whether leadership is born or made with the related theories and examples.

The teams coached by the successful Turkish basketball coach, Çetin Yılmaz, had reached the finals of the Turkish Basketball League six times and became champions three times. He assumed the coaching position of the Tuborg basketball team in December 2005. Although Tuborg’s Turkey branch made a serious financial investment in basketball, they were at the bottom of the league in the middle of the season. When Yılmaz took over the coaching position, the Tuborg basketball team’s main objective was not to be relegated from the top league in the 2005–2006 season. The team, working very hard, overcame the fear of relegation in two months but still had a very symbolic goal in front of it: winning the most prestigious game of the season by defeating the Karşıyaka team. However, in the last minutes of the game, with the influence of passionate Karşıkaya fans, the Tuborg team got scared and lost the game. At the end of the match, the club president entered the locker room and started shouting at the players, forcing the coach to face a severe dilemma. Either he would remain silent and risk damaging his leading position in the eyes of the players, or he would risk being fired by going against the president, even though he thought the president was right in what he said.

The target audience of this case study is undergraduate students. The field of study is sports management, leadership and coaching. This case study can be used in management, organizational behaviour and sports management courses while covering leadership and coaching topics.

The purpose of this chapter is to characterize fictitious capital and fictitious profits as extreme expressions of the fetishism of capital. Considering the incessant search for valorization and allowing for fictitious forms of capital, the subject of this study is at the center of the dynamics of recent capitalist accumulation, especially when we take into account the capitalist crises over the last four or five decades. Its mechanism of fictitious valorization (M – M′), a decisive dimension of contemporary capitalism, is contradictory, based on the growing obstacles to the extraction of surplus value on an expanded scale, and therefore the real valorization of capital. At the same time, we support the idea that this mass of overaccumulated capital produces profits unrelated to surplus value, that is fictitious profits, further intensifying the fetishistic and contradictory nature of capitalism.
