I rapporti di collaborazione tra vettori

L’elaborato ha ad oggetto l’analisi delle possibili forme di collaborazione tra vettori nei diversi settori del trasporto, con particolare attenzione all’ambito aeronautico e marittimo. Negli ultimi decenni l’incremento del livello di concorrenza tra i competitors su scala planetaria, a seguito della progressiva liberalizzazione e globalizzazione dei trasporti, ha indotto i vettori ad adottare nuove strategie commerciali dirette alla condivisione del rischio, alla riduzione dei costi di esercizio, all’espansione delle proprie reti e alla flessibilizzazione dei processi interni di adeguamento alle continue espansioni e contrazioni del mercato. Hanno, così, fatto la loro comparsa modelli contrattuali nuovi che differiscono per struttura, livello di integrazione delle parti coinvolte e grado di complessità dell’accordo. Nell’elaborato, pertanto, sono state attentamente esaminate le molteplici figure giuridiche generate dalla prassi commerciale, come gli accordi di codesharing, interlining, wet lease, dry lease, franchising, le grandi alleanze strategiche presenti sia in ambito aeronautico, sia in quello marittimo, le Conferences e i Consorzi. La ricerca, in particolare, è focalizzata, alla luce della prassi contrattuale e della normativa nazionale, comunitaria ed internazionale vigente, sui problemi di qualificazione giuridica di tali accordi e, conseguentemente, sulla disciplina di volta in volta ad essi applicabile, sul loro oggetto, regolamento contrattuale e contenuto. Si è proceduto poi ad uno studio comparativo-contrastivo delle differenze tra le varie forme di partnership e all’approfondimento delle questioni concernenti la tutela degli utenti dei servizi di trasporto, siano essi passeggeri o mittenti. Sono affrontati, infatti, con accurata indagine i profili di responsabilità dei vettori coinvolti, sulla base del quadro normativo di riferimento. Nel corso della ricerca si è data anche particolare attenzione all’analisi della compatibilità degli accordi tra vettori con la disciplina comunitaria della concorrenza, registrando una tendenza della Comunità a piegare l’interpretazione delle norme in materia alle superiori esigenze dell’economia, in considerazione delle peculiarità del mercato del trasporto.

Integration of cognitive and affective processes in perception and decision-making

The relationship between emotion and cognition is a topic that raises great interest in research. Recently, a view of these two processes as interactive and mutually influencing each other has become predominant. This dissertation investigates the reciprocal influences of emotion and cognition, both at behavioral and neural level, in two specific fields, such as attention and decision-making. Experimental evidence on how emotional responses may affect perceptual and attentional processes has been reported. In addition, the impact of three factors, such as personality traits, motivational needs and social context, in modulating the influence that emotion exerts on perception and attention has been investigated. Moreover, the influence of cognition on emotional responses in decision-making has been demonstrated. The current experimental evidence showed that cognitive brain regions such as the dorsolateral prefrontal cortex are causally implicated in regulation of emotional responses and that this has an effect at both pre and post decisional stages. There are two main conclusions of this dissertation: firstly, emotion exerts a strong influence on perceptual and attentional processes but, at the same time, this influence may also be modulated by other factors internal and external to the individuals. Secondly, cognitive processes may modulate emotional prepotent responses, by serving a regulative function critical to driving and shaping human behavior in line with current goals.

Understanding the Combined Role of Internal and External Factors in New Service Development Process within the Professional Knowledge Intensive Business Service Firms

Our research asked the following main questions: how the characteristics of professionals service firms allow them to successfully innovate in exploiting through exploring by combining internal and external factors of innovation and how these ambidextrous organisations perceive these factors; and how do successful innovators in professional service firms use corporate entrepreneurship models in their new service development processes? With a goal to shed light on innovation in professional knowledge intensive business service firms’ (PKIBS), we concluded a qualitative analysis of ten globally acting law firms, providing business legal services. We analyse the internal and factors of innovation that are critical for PKIBS’ innovation. We suggest how these firms become ambidextrous in changing environment. Our findings show that this kind of firms has particular type of ambidexterity due to their specific characteristics. As PKIBS are very dependant on its human capital, governance structure, and the high expectations of their clients, their ambidexterity is structural, but also contextual at the same time. In addition, we suggest 3 types of corporate entrepreneurship models that international PKIBS use to enhance innovation in turbulent environments. We looked at how law firms going through turbulent environments were using corporate entrepreneurship activities as a part of their strategies to be more innovative. Using visual mapping methodology, we developed three types of innovation patterns in the law firms. We suggest that corporate entrepreneurship models depend on successful application of mainly three elements: who participates in corporate entrepreneurship initiatives; what are the formal processes that enhances these initiatives; and what are the policies applied to this type of behaviour.

Adaptive and Maladaptive Implications of Reinforcement Learning Processes: Fronto-Striatal Loops and Behavioural Correlates

That humans and animals learn from interaction with the environment is a foundational idea underlying nearly all theories of learning and intelligence. Learning that certain outcomes are associated with specific actions or stimuli (both internal and external), is at the very core of the capacity to adapt behaviour to environmental changes. In the present work, appetitive and aversive reinforcement learning paradigms have been used to investigate the fronto-striatal loops and behavioural correlates of adaptive and maladaptive reinforcement learning processes, aiming to a deeper understanding of how cortical and subcortical substrates interacts between them and with other brain systems to support learning. By combining a large variety of neuroscientific approaches, including behavioral and psychophysiological methods, EEG and neuroimaging techniques, these studies aim at clarifying and advancing the knowledge of the neural bases and computational mechanisms of reinforcement learning, both in normal and neurologically impaired population.
