| Abstract: | Dans le contexte marocain, les compétitions sportives telles que la Coupe d'Afrique des Nations (CAN) de 2025 et la Coupe du Monde de 2030 présentent des opportunités majeures de développement pour le pays. Ces événements fournissent une plateforme propice à l'amélioration des infrastructures, en particulier des stades de football, nécessaires pour accueillir avec succès ces compétitions de renom. La qualité des stades est essentielle à la création d'un spectacle de haut niveau, cependant, des actions rigoureuses sont nécessaires afin que ces installations puissent véritablement catalyser la professionnalisation des clubs de football locaux. L'objectif du présent article est d'identifier, à travers une analyse de la littérature en la matière, la contribution des infrastructures sportives à la professionnalisation des clubs de football. Pour cela, nous allons présenter, dans un premier temps, un état de l'art de la professionnalisation dans le contexte sportif par la suite nous aborderons la problématique de l'investissement dans les infrastructures sportives afin de ressortir des hypothèses de recherche pour une future investigation empirique. Cette recherche a mis en lumière l'importance cruciale des IS dans le processus de professionnalisation, ces investissements ont été identifiés comme des leviers pour améliorer la performance sportive des clubs ainsi que garantir leurs autonomie financière. |

| Abstract: | Competitions often suffer from biased judgments by officials tied to their social identities. In international cricket, home nation umpires favoured home teams, but neutral umpires were introduced successfully to address this bias. However, the COVID-19 pandemic prompted the return of home umpires, creating a natural experiment amid heightened scrutiny, modern technology, and sometimes empty stadiums. Consistent with the predictions of our behavioural model, we find no evidence of in-group bias during the pandemic; instead, we observe evidence of over-compensation. The pre-pandemic home team advantage in 'leg before wicket' decisions vanished, with home umpires seemingly favouring the away opposition, compared with neutral umpires in the period before, especially in more marginal or difficult decisions. This suggests that awareness and scrutiny can not only eliminate identity-driven judgement bias but may even reverse it. |

| Abstract: | This study analyses the factors influencing coaching decisions when substituting players, particularly in light of the rule change from three to five permitted substitutions. To this end, 161 coaches and their decisions are analysed in 1, 836 Bundesliga matches from 2017/2018 to 2022/2023, whereby the tactical components, timing and age structure of the substitutions are examined. A total of 13, 363 substitution situations are therefore analysed at the level of individual decisions. The main influencing factors are the age of the coach, professional experience and the length of time spent working with the team. Spectator numbers and goal difference hardly play a role. |
| Abstract: | Diese Studie untersucht die Einflussfaktoren auf Trainerentscheidungen bei Spielerwechseln, insbesondere vor dem Hintergrund der Regeländerung von drei auf fünf erlaubte Wechsel. Dazu werden 161 Trainer und deren Entscheidungen in 1.836 Bundesligaspielen von 2017/2018 bis 2022/2023 analysiert, wobei die taktische Komponente, der Zeitpunkt und die Altersstruktur der Wechsel untersucht werden. Insgesamt werden somit 13.363 Wechselsituationen auf Ebene der individuellen Entscheidungen betrachtet. Wesentliche Einflussfaktoren sind das Alter des Trainers, die Berufserfahrung und die Dauer der Zusammenarbeit mit der Mannschaft. Zuschauerzahlen und Tordifferenz spielen hingegen kaum eine Rolle. |

| Abstract: | Recent advancements in generative artificial intelligence (AI) have transformed collaborative work processes, yet the impact on team performance remains underexplored. Here we examine the role of generative AI in enhancing or replacing traditional team dynamics using a randomized controlled experiment with 435 participants across 122 teams. We show that teams augmented with generative AI significantly outperformed those relying solely on human collaboration across various performance measures. Interestingly, teams with multiple AIs did not exhibit further gains, indicating diminishing returns with increased AI integration. Our analysis suggests that centralized AI usage by a few team members is more effective than distributed engagement. Additionally, individual-AI pairs matched the performance of conventional teams, suggesting a reduced need for traditional team structures in some contexts. However, despite this capability, individual-AI pairs still fell short of the performance levels achieved by AI-assisted teams. These findings underscore that while generative AI can replace some traditional team functions, more comprehensively integrating AI within team structures provides superior benefits, enhancing overall effectiveness beyond individual efforts. |
