    The Importance of Being A Case. Collapsing of the Law upon the Case in Interlegal Situations

    No full text
    The article aims at delving into the concept of a concrete ‘case’ within the general framework of the theory of interlegality. The argumentation starts from the acknowledgment that it is not possible to identify in advance and in abstract terms the rule governing the case, and according to which it should be adjudicated: in the interlegal scenario no other ordering criterion can be ascertained but for a reference to the interplay of regulatory claims in respect of the ‘facts of the case’. The analysis firstly focuses upon the concept of the case from a theoretical point of view. It then highlights the relationship between facts as empirical ground and the case as the result of the qualification by multiple normativities. Lastly, after stressing the importance of ascertaining facts in order not to misunderstand the content and import of legal cases, it explains why in the interlegal scenario a paradigm shift can be acknowledged: from the abstract rule valid in a given jurisdiction, to the centrality of the case for the identification of the law governing it

    Environmental policies and commitment is forcing a strong push towards electrification of human activities. Efforts are oriented to progressively dismiss old and outdated Internal Combustion Engines, replacing oil energy sources with electricity vectors. An important switch is involving transportation sector, responsible for 16% of global emissions produced, where the electrification process is converting the private mobility to the use of more sustainable electric vehicles. The drawbacks related to the battery capacity and range is limiting the diffusion among the whole territory, especially where a lack of charging infrastructure is persistent. Therefore, a focus on the adopted driving behaviour must be set to carry benefits in energy saving and potentially extending range. The present paper provides an analysis on different driving behaviour based on real-world data. An experimental campaign is described to acquire different driving styles during test-runs on a real route. An electric vehicle model is also developed in parallel and validated on the real dataset. A test route is identified in the southern region of Puglia in Italy, centered around the city of Lecce, and altitude and speed profiles are acquired and processed into the model. Test-runs were first clustered based on the driver type, then according to the level of auxiliary power consumption. Then, with the help of EV model, a more detailed analysis could be set to retrieve meaningful motivations behind the trends gathered between the two driving styles, especially focusing on the type of road. Results allowed to extrapolate trends between energy consumption and driving styles, showing a considerable impact on the battery usage. A +5% SoC is estimated if an aggressive driving style is adopted, while the impact of auxiliary power is predominant with an eco-driving style, taking into account uneven testing conditions

    The efforts in pushing toward the electric mobility is enhancing improvements for batteries and vehicle performance to extend the range, making the Electric Vehicle (EV) a competitive couce alongside conventional Internal Combustion Engine vehi-cles. However, less efforts are spent to highlight the importance of changing the driving style, to avoid unpleasant drawbacks for battery durability and range drop. In this research, a psychologi-cal insight is provided to understand the pattern of driving styles which can affect the energy consumption while driving an Electric Vehicle. The experimental setup used to perform tests with 26 different users is provided through a Virtual Reality (VR) test bench, aimed to recreate a real trafficked route with both urban and highway paths. The psycological elements are provided to constitute the basis of the analysis, that is then illustrated through energy consumption assessment

    Increasing transportation sustainability from scratch: Small city context

    Reshaping transportation offer in metropolitan and suburban areas plays a fundamental role in complying with environmental commitment. A sustainable public transportation system is crucial to reduce air pollution and the overall environmental impact of transportation sector, going beyond mere displacement solutions offered. This paper presents how to implement a sustainable transportation solution starting from green shift investments in a small citizen centre. Two new bus lines were examined and planned to adapt the actual service to a potentially-evolving demand. Electric vehicle types were selected to compare full-electric with hydrogen traction systems. Moreover, particular attention was paid to the energy supply chain through Well-To-Tank analysis. Battery vehicles appear to be preferred, at the moment, when reliance on the national grid is prevailing showing affordable costs 1.8 €/km, +0.5 €/km with respect to the actual Diesel operations. However, also hydrogen energy vector resulted a competitive choice. Uncertainty in the market demand plays a great role and if reduced progressively, it allows to recover the heavy investments, given the high cost of ownership of 2.8 €/km. The research is enriched by the collaboration of a managerial representative of Arriva Italia, operator of local public transportation and an exponent of the scientific community
