Trade sustainability impact assessment (SIA) on the comprehensive economic and trade agreement (CETA) between the EU and Canada: Final report
No full textCommissioned by the European Commission, the Final Report for the EU-Canada Sustainability Impact Assessment (SIA) on the EU-Canada Comprehensive Economic and Trade Agreement (CETA) provides a comprehensive assessment of the potential impacts of trade liberalisation under CETA. The analysis assesses the economic, social and environmental impacts in Canada and the European Union in three main sectors, sixteen sub-sectors and across seven cross-cutting issues. It predicts a number of macro-economic and sector-specific impacts. The macro analysis suggests the EU may see increases in real GDP of 0.02-0.03% in the long-term from CETA, whereas Canada may see increases of 0.18-0.36%. The Investment section of the report suggests these numbers could be higher when factoring in investment increases. At the sectoral level, the study predicts the greatest gains in output and trade to be stimulated by services liberalisation and by the removal of tariffs applied on sensitive agricultural products. It also suggests CETA could have a positive social impact if it includes provisions on the ILO’s Core Labour Standards and Decent Work Agenda. The study also details a variety of impacts in various “cross-cutting” components of CETA. It finds CETA would stimulate investment in Canada, and to a lesser extent in the EU; and finds costs outweigh the benefits of including controversial NAFTA-style investor-state dispute settlement (ISDS) provisions in CETA. It predicts potentially imbalanced benefits from a government procurement (GP) chapter. The study assumes CETA will lead to an upward harmonisation in intellectual property rights (IPR) regulations, particularly in Canada, which will have a number of effects. It predicts some notable impacts in terms of competition policy, as well as trade facilitation, free circulation of goods and labour mobility.EU-Canada Sustainability Impact Assessment; SIA; EU-Canada Comprehensive Economic and Trade Agreement; Comprehensive Economic and Trade Agreement; CETA; government procurement; investor-state provisions; ISDS; competition policy; Dan Prud'homme; trade impact assessment

No full textProcessi di trasporto classico e quantistico nelle nano-bio-strutture: un nuovo modello teorico e applicazioni
No full textIl lavoro di tesi di dottorato ha lo scopo di studiare teoricamente il processo di trasporto di carica in nanobiostrutture, quali ad esempio nanoparticelle e nanofili, da un punto di vista classico e quantistico. L’argomento è di forte interesse dato il continuo miglioramento tecnologico che rende disponibili un numero crescente di dispositivi con dimensioni caratteristiche di pochi nanometri il cui comportamento elettrico non sempre è spiegabile dai modelli teorici già noti. Viene proposto un nuovo modello che permette di valutare in forma analitica l’andamento della funzione di correlazione delle velocità alla temperatura T, dello spostamento quadratico medio e del coefficiente di diffusione D anche su scale temporali estremamente ridotte, dell’ordine del tempo medio tra gli urti dei portatori di carica. Il modello proposto è stato utilizzato per analizzare dati sperimentali dei materiali più comunemente utilizzati e studiati in tale settore, ossia l’ossido di zinco (ZnO), il biossido di titanio (TiO2), l’arseniuro di gallio (GaAs), il silicio (Si) e i nanotubi di carbonio “single walled” (SWCN). Tale modello non richiede l’aggiunta di parametri non pienamente giustificabili fisicamente, come avviene ad esempio nel caso del modello di Smith e fornisce risultati nuovi (come un’alta diffusività iniziale e fenomeni iniziali di natura oscillatoria in nanodispositivi anche a livello sensoristico), che si prestano a conferma da parte dell’attività sperimentale.My doctorate thesis has the purpose to study theoretically the transport processes in nanobiostructures, like nanoparticles and nanowires, from a classical and quantum point of view. The matter is of high interest considering the continuous technological improvement, which makes possible an increasing number of devices with characteristic dimensions of few nanometers, whose electric behavior is not always explainable with the known available theoretical models. A new model is proposed, which allows to evaluate in analytical modality the velocities correlation function at temperature T, the mean square deviation of position and the diffusion coefficient D, also on extremely small temporal scales, of order of the average time among the collisions of carriers. The proposed model has been used for analyzing experimental data of the most commonly used and studied materials in such sector, i.e Zinc Oxide (ZnO), Titanium Dioxide (TiO2), Gallium Arsenide (GaAs), Silicon (Si) and "single walled" Carbon Nanotubes (SWCN). This new model doesn't require not fully physically justified parameters, as for example in the Smith model, and it offers new results (like a high initial diffusivity and initial oscillating phenomena in nanodevices also at sensoristic level), which are material of confirmation from the experimental activity
