Regulating Vertical Agreements: A Comparative Law & Economics analysis of Brazil and Europe

This PhD thesis discusses antitrust enforcement of anti-competitive vertical agreements in Europe and in Brazil from an institutional perspective. It considers both the evolution of the legal framework and the application of the existing policies, with the analysis of case studies. The research highlights the main challenges of the current approaches adopted by the competition authorities in these jurisdictions and formulates specific proposals for future improvements. Because the Brazilian competition rules were originally inspired by the European legal framework, this thesis also summarizes the contemporary discussions regarding comparative law and the efficiency of transplanting laws and good practices. In a Law & Economics perspective, vertical agreements have always been a paradoxical topic and constitute one of the most dynamic disputes for antitrust enforcement. The reason for that concern is the fact that those contracts among companies are complex in nature. Taking into account this background, the thesis provides an original analysis of the pro- and anti-competitive effects of vertical agreements, based on the classical literature of Law & Economics. One of the novelties of the research is the extension of the economic analysis of vertical agreements to also consider new forms of contractual abuses in the context of digital markets, such as the contractual restrictions that are being put I practice in e-commerce platforms. The international comparative approach focuses on the Brazilian and European experiences, and opens up a reflection about the policy recommendations applied to several countries with similar economic and institutional realities.

At the intersection of Behavioural Economics, Nudging and Regulation: Rethinking the process of nudge design for regulation

Alongside the developments in behavioural economics, the concept of nudge was introduced as an intervention able to guide individual behaviour towards better choices without using coercion or incentives. While behavioural teams were created inside governmental units and regulatory authorities, nudging emerged in regulatory discourse, being increasingly regarded as a regulatory instrument that could overcome the disadvantages of other tools. This thesis analyses the viability of incorporating nudges into regulation. In particular, it investigates the implications for regulators of bringing iterative experimental testing – a widespread nudge design methodology outside regulation – into their own design practices. Nudges outside regulation are routinely designed using experiments of all kinds. This thesis intends to answer whether design premises rooted in iterative experimentation are still valid in the regulatory space, an arena that nudging entered into and that is distinct from the one where it originally emerged. The design and provision of nudges using the premises of iterative experimental testing is possible, but at a cost and burden for regulatory nudge designers. Therefore, the thesis evaluates how this burden can be reduced, in particular how nudges can be feasibly designed and provided through regulation or, put differently, how to more efficiently design and provide nudging as a regulatory tool.

Better Regulation in Latin American Countries: A tool for accountability?

In the last few years, a steadily increasing number of Latin American countries have been adopting policy assessment instruments and new governance structures for them, as part of their policymaking process. Even though the literature argues that these instruments serve, among other things, as tools for accountability, for this to be so, it is necessary to take into account the legal system, decision-making process, and regulatory relationships that exist in the adopting countries. This Thesis researches the policy assessment arrangements adopted and implemented in the Latin American region to understand why are these countries adopting and implementing tools for policy evaluation? Can this contribute towards regulatory accountability, and if so, in which conditions? The Thesis first analyzes the rationales that these countries might have to adopt these regulatory policy arrangements. It then studies the various tools used for policy assessment, paying attention to the scope of the assessments, the times and the stages on which regulations are assessed, referred to as the Policy Evaluation Cycle (PEC), as well as to the governance of these processes. The Thesis develops a framework where each of these components are organized and classified based on which goals or rationales they serve. This can assist countries on deciding how to implement their policy evaluation arrangements, to serve their own goals. Since all of the studied countries have presidential systems, this Thesis studies how regulations are made in this system, and the multiple needed delegations for policymaking, which results in various regulatory relationships. Thus, the desired accountability of policymakers towards their different forums makes relevant the adoption this agenda for regulatory accountability reasons. Bringing to together the literatures on public law, accountability and policy evaluation, this Thesis builds a framework for assessing the contribution towards accountability that each stage of the PEC might have in a specific regulatory relationship. The framework shows to which degree the stages, and the cycle as a whole, contribute towards accountability in specific relationships of a presidential constitutional system. The results evidence that even when a policy assessment structure might contribute towards accountability, this contribution is not absolute as it only operates in specific regulatory relationships, and even more, only in some stages of the PEC contributing at different degrees. This framework can be used by governments or regulatory agencies as an instrument to assess the contribution to accountability of their existing or potential regulatory policy structures in order to improve it.

Mode-I fracture parameters of quasi-brittle materials: direct evaluation using DIC and relationship with Mode-II interfacial parameters

The objective of this thesis is the investigation of the Mode-I fracture mechanics parameters of quasi-brittle materials to shed light onto the influence of the width and size of the specimen on the fracture response of notched beams. To further the knowledge on the fracture process, 3D digital image correlation (DIC) was employed. A new method is proposed to determine experimentally the critical value of the crack opening, which is then used to determine the size of the fracture process zone (FPZ). In addition, the Mode-I fracture mechanics parameters are compared with the Mode-II interfacial properties of composites materials that feature as matrices the quasi-brittle materials studied in Mode-I conditions. To investigate the Mode II fracture parameters, single-lap direct shear tests are performed. Notched concrete beams with six cross-sections has been tested using a three-point bending (TPB) test set-up (Mode-I fracture mechanics). Two depths and three widths of the beam are considered. In addition to concrete beams, alkali-activated mortar beams (AAMs) that differ by the type and size of the aggregates have been tested using the same TPB set-up. Two dimensions of AAMs are considered. The load-deflection response obtained from DIC is compared with the load-deflection response obtained from the readings of two linear variable displacement transformers (LVDT). Load responses, peak loads, strain profiles along the ligament from DIC, fracture energy and failure modes of TPB tests are discussed. The Mode-II problem is investigated by testing steel reinforced grout (SRG) composites bonded to masonry and concrete elements under single-lap direct shear tests. Two types of anchorage systems are proposed for SRG reinforced masonry and concrete element to study their effectiveness. An indirect method is proposed to find the interfacial properties, compare them with the Mode-I fracture properties of the matrix and to model the effect of the anchorage.

Study of medicinal and food plants as a source of biologically active compounds.

In the last few decades, scientific evidence has pointed out the health-beneficial effects of phenolic compounds in foods, including a decrease in risk of developing degenerative and chronic diseases, known to be caused by oxidative stress. In this frame can be inserted research carried out during my PhD thesis, which concerns the phytochemical investigation of phenolic composition in sweet cherries (Prunus avium L.), apple fruits (Malus domestica L.) and quinoa seeds (Chenopodium quinoa Willd.). The first project was focused on the investigation of phytochemical profile and nutraceutical value of fruits of new sweet cherry cultivars. Their phenolic profile and antioxidant activity were investigated and compared with those of commonly commercialized cultivars. Their nutraceutical value was evaluated in terms of antioxidant/neuroprotective capacity in neuron-like SH-SY5Y cells, in order to investigate their ability to counteract the oxidative stress and/or neurodegeneration process The second project was focused on phytochemical analysis of phenolic compounds in apples of ancient cultivars with the aim of selecting the most diverse cultivars, that will then be assayed for their anti-carcinogenic and anti-proliferative activities against the hepato-biliary and pancreatic tumours. The third project was focused on the analysis of polyphenolic pattern of seeds of two quinoa varieties grown at different latitudes. Analysis of phenolic profile and in vitro antioxidant activity of seed extracts both in their free and soluble-conjugated forms, showed that the accumulation of some classes of flavonoids is strictly regulated by environmental factors, even though the overall antioxidant capacity does not differ in quinoa Regalona grown in Chile and Italy. During the internship period carried out at the Department of Organic Chemistry at Universidad Autónoma de Madrid (UAM), it was achieved the isolation of two pentacyclic triterpenoids, from an endemic Peruvian plant, Jatropha macrantha Müll. Arg., with bio-guided fractionation technique.

Before It's Too Late: INGOs' Handling of Conflict Risk in South Sudan

What do international non-governmental organisations (INGOs) do before and during the escalation of conflicts? The academic literature primarily focuses on these organisations' behaviour during an evident crisis rather than on how they anticipate the escalation of conflicts, assess the situation in which they find themselves, and decide on strategies to cope with the possibility of upcoming violence. Such lopsided focus persists despite calls for INGOs to become more proactive in managing their programmes and their staff members' safety. Mindful of this imbalance, the present study provides a causal explanation of how decision-makers in INGOs anticipate and react to the risk of low-level violence escalating into full-blown conflicts. This thesis aims to explain these actors' behaviour by presenting it as a two�step process involving how INGOs conduct risk assessments and how they turn these assessments into decisions. The study performs a structured, focused comparison of seven INGOs operating in South Sudan before the so-called Juba Clashes of 7 July 2016. Based on an analytical framework of INGO decision�making stemming from political risk analysis, organisational decision-making theory and conflict studies literature, the study reconstructs decision-making via process-tracing combined with mixed methods of data collection.

Che cosa significa emancipazione? Organizzazione sociale, norme giuridiche e potere paterno dalla Rivoluzione francese agli anni Quaranta dell'Ottocento

La tesi presenta un’analisi storico-concettuale del concetto di emancipazione in Francia tra la Rivoluzione francese e gli anni Quaranta dell’Ottocento a partire dalla centralità delle donne nel processo rivoluzionario e dal problema del potere paterno e dell’ordine della famiglia. Da questa prospettiva viene ricostruito il momento di affermazione del significato moderno del concetto: prima con l’Illuminismo e poi con la Rivoluzione francese si determina un progressivo allargamento semantico che farà posto a significati politico-sociali inediti e a una serie di soggetti imprevisti. La Rivoluzione presenta infatti sulla scena un soggetto collettivo, già maturo, che dà forma all’emancipazione rivoluzionaria. Quest’ultima richiede una specifica scienza in grado di arginare i suoi effetti politici più pericolosi senza tradirne le premesse formali. A questo risponde l’Idéologie come scienza sociale sul finire della Rivoluzione. Se le donne in questi anni si mobilitano a partire dall’emancipazione rivoluzionaria, esse rappresentano al tempo stesso un problema fondamentale per l’ordine rivoluzionario come mostra il dibattito sul potere paterno che fa luce sul passaggio, fondamentale per il concetto di emancipazione, dal potere di emancipare del padre a quello dello Stato emancipatore. Gli esiti di questo dibattito si trovano nel Codice civile e nella sua emancipazione codificata, che definisce i confini giuridici e formali dell’emancipazione rivoluzionaria e le sue gerarchie. In seguito, la tesi ricostruisce le trasformazioni del concetto all’indomani della Rivoluzione nella dottrina di Saint-Simon e dei suoi allievi. Questa sarà all’origine del discorso che si sviluppa in Francia tra gli anni Trenta e Quaranta sul problema dell’emancipazione della donna che trova espressione negli scritti delle donne saint-simoniane. La tesi si ferma alle porte degli anni Quaranta quando l’emancipazione nel suo significato moderno si stabilizza e diventa un vero e proprio concetto di movimento, espressione di processi di emancipazione che si erano preparati negli anni precedenti.

The Allocation of Asylum Responsibilities in the EU: a Law & Economics Analysis

This dissertation focuses on how the design of the EU asylum allocation system, the system that allocates the EU’s asylum duties to its member states, relates to the development of asylum crises. The current EU asylum allocation system, the Dublin system, has in the literature frequently been blamed as an important factor that contributed to the events that occurred during the 2015/2016 EU Asylum Crisis. In the first part of this dissertation, I use a Law & Economics methodology based on rational choice theory to study how the Dublin system creates behavioural incentives for both asylum seekers and member states and how this relates to the events during the 2015/2016 EU Asylum Crisis. In the second part, I analyse how behavioural incentives for asylum seekers and member states would change if the EU would replace the Dublin system with a so-called (tradable) quota system. By comparing the outcomes of the first and the second part of the dissertation I make some normative recommendations on desirable features for an EU asylum allocation system that provides better incentives for asylum seekers and member states.

Populism as a battlefield Populist actors and their representation on social and legacy media during the european parliament elections 2019 in Finland, Italy and the Netherlands

The objective of the present research is to describe and explain populist actors and populism as a concept and their representation on social and legacy media during the 2019 EU elections in Finland, Italy and The Netherlands. This research tackles the topic of European populism in the context of political communication and its relation to both the legacy and digital media within the hybrid media system. Departing from the consideration that populism and populist rhetoric are challenging concepts to define, I suggest that they should be addressed and analyzed through the usage of a combination of methods and theoretical perspectives, namely Communication Studies, Corpus Linguistics, Political theory, Rhetoric and Corpus-Assisted Discourse Studies. This thesis considers data of different provenance. On the one hand, for the Legacy media part, newspapers articles were collected in the three countries under study from the 1st until the 31st of May 2019. Each country’s legacy system is represented by three different quality papers and the articles were collected according to a selection of keywords (European Union Elections and Populism in each of the three languages). On the other hand, the Digital media data takes into consideration Twitter tweets collected during the same timeframe based on particular country-specific hashtags and tweets by identified populist actors. In order to meet the objective of this study, three research questions are posed and the analysis leading to the results are exhaustively presented and further discussed. The results of this research provide valuable and novel insights on how populism as a theme and a concept is being portrayed in the context of the European elections both in legacy and digital media and political communication in general.

"Tradizione romanistica" e principi generali del diritto: Il dibattito italiano tra Otto e Novecento

Il presente lavoro verte sul ruolo svolto dal diritto romano e – più in generale – dalla “tradizione romanistica” all'interno del sistema giuridico nazionale posteriore alla codificazione civile del 1865. L'attenzione è rivolta principalmente all'art. 3 delle Disposizioni preliminari del Codice del 1865 con il suo riferimento ai 'principi generali del diritto' e, dunque, all'analogia iuris. La prima parte dello studio si concentra sull'analisi di alcune voci della scienza giuridica italiana tra Otto e Novecento, nei loro diversi approcci – laddove riscontrabili – rispetto allo studio e al recupero (in chiave moderna) del diritto romano. La seconda parte è invece dedicata all'esame della prassi giudiziaria e, più specificamente, delle Corti di Cassazione. In questa fase si persegue un duplice obiettivo: da un lato, verificare se, ed eventualmente in che misura, il diritto romano possa ancora svolgere un ruolo nella (moderna) giurisprudenza di legittimità; dall'altro, valutare la concreta possibilità, prospettata da una parte della scienza giuridica, di ricorrere in Cassazione per impugnare una sentenza asseritamente contraria ai principi generali del diritto sanciti dall'art. 3 co. 2 delle Preleggi. L'analisi prende dunque le mosse dal contenuto delle singole decisioni della Cassazione, per poi passare all'esegesi dei frammenti di volta in volta richiamati; infine, si concluderà con un'operazione di sintesi volta a valutare, per ciascun caso, la coerenza (giuridica) del ragionamento analogico.

Structural health monitoring of storage tanks

In this thesis, Ph.D candidate presents a compact sensor node (SN) designed for long-term and real-time acoustic emission (AE) monitoring of above ground storage tanks (ASTs). Each SN exploits up to three inexpensive low-frequency sensors based on piezoelectric diaphragms for effective leakage detection, and it is capable by means of built-in Digital Signal Processing functionalities to process the acquired time waveforms extracting the AE features usually required by testing protocols. Alternatively, capability to plug three high frequency AE sensors to a SN for corrosion simulated phenomena detection is envisaged and demonstrated. Another innovative aspect that the Ph.D candidate presents in this work is an alternative mathematical model of corrosion location on the bottom of the AST. This approach implies considering the three-dimensional localization model versus the two-dimensional commonly used according to the literature. This approach is aimed at significant optimization in the number of sensors in relation to the standard approach for solving localization problems as well as to allow filtering the false AE events related to the condensate droplets from AST ceiling. The technological implementation of this concept required the solution of a number of technical problems, such as the precise time of arrival (ToA) signal estimation, vertical localization of the AE source and multilaration solution that were discussed in detail in this work. To validate the developed prototype, several experimental campaigns were organized that included the simulation of target phenomena both in laboratory conditions and on a real water storage tank. The presented test results demonstrate the successful application of the developed AE system both for simulated leaks and for corrosion processes on the tank bottom. Mathematical and technological algorithms for localization and characterization of AE signals implemented during the development of the prototype are also confirmed by the test results.

Neuroprotective role of nutraceutical and phytochemical components

Neurodegenerative diseases (NDs) are characterized by a multifactorial etiology, in which oxidative stress and inflammation are the main causative factors. For this reason, increasing attention is being paid to the characterization and the identification of nutraceuticals and phytochemicals with intrinsic pleiotropic activity. Moreover, in a Circular Economy perspective, these natural compounds can be obtained also from renewable resources derived from the food industry by-products and can be used for both preventive and therapeutic purposes. The aim of this PhD program was to identify nutraceuticals and phytochemicals, both as extracts and pure compounds, and obtained from both plant and renewable sources, which due to their antioxidant and anti-inflammatory properties, were able to counteract cellular and molecular alterations that characterize NDs. Their neuroprotective potential has been evaluated in an in vitro model of neuroinflammation (the LPS-activated BV-2 microglial cell line), and/or in an in vitro model of neuronal oxidative stress (the neuron-like SH-SY5Y cell line differentiated with retinoic acid and exposed to H2O2). Four different projects, although deeply linked by the aforementioned common goal, have been discussed in this thesis: 1_ Impact of phenolic profile of different cherry cultivars on the potential neuroprotective effect in SH-SY5Y cells. 2_Anti-inflammatory activities of Spilanthol-rich essential oil from Acmella oleracea (L.). 3_Study of the anti-inflammatory activity of novel tacrine derivatives with lipids extracted from cashew nutshell liquid. 4_Coffee Silverskin (CSS) and Spent Coffee Grounds (SCG): coffee industry by-products as a promising source of neuroprotective agents. In general, it is, therefore, possible to conclude that the natural compounds studied in this thesis have been proven, due to their antioxidant and/or anti-inflammatory properties, to be valid preventive and therapeutic strategies for the treatment of NDs, to improve the life quality of these patients and of the general population by preventing and combating the onset of these deleterious diseases.

Speed, legislatures and international treaties: Evidence from Mercosur

What causes faster or slower procedures in the parliaments when considering international treaties? This question motivates the current research, which aims to understand how the nature of coalitions influence the duration of the legislative processes. For this, the analysis covers all the treaties signed by Mercosur between 1991 and 2021 and the internalisation processes in four member states (Argentina, Brazil, Paraguay and Uruguay). It observes how long each parliament took to approve the treaties and which was the effect of political and economic variables. A mixed-methods approach was adopted for the empirical research, combining Survival Analysis, Qualitative Comparative Analysis and Process Tracing. While the quantitative work investigates all the cases, the qualitative study illuminates the enlargement of Mercosur, with in-depth analysis of the Paraguayan approval of the Venezuelan and Bolivian accessions. This study provides important insights into the role of national legislatures in the Latin American regionalism, concluding that the government-opposition cleavage drives the parliamentarians’ behaviour on the topic of regional integration. The study also contributes to the field Mercosur studies with the characterisation of the treaties ratified domestically, by undertaking a longitudinal analysis at the 30th anniversary of the bloc.

Applicazioni tecnologiche e nuovi metodi di valutazione della performance negli sport acquatici

Nello sport di alto livello l’uso della tecnologia ha raggiunto un ruolo di notevole importanza per l’analisi e la valutazione della prestazione. Negli ultimi anni sono emerse nuove tecnologie e sono migliorate quelle pre-esistenti (i.e. accelerometri, giroscopi e software per l’analisi video) in termini di campionamento, acquisizione dati, dimensione dei sensori che ha permesso la loro “indossabilità” e l’inserimento degli stessi all’interno degli attrezzi sportivi. La tecnologia è sempre stata al servizio degli atleti come strumento di supporto per raggiungere l’apice dei risultati sportivi. Per questo motivo la valutazione funzionale dell’atleta associata all’uso di tecnologie si pone lo scopo di valutare i miglioramenti degli atleti misurando la condizione fisica e/o la competenza tecnica di una determinata disciplina sportiva. L’obiettivo di questa tesi è studiare l’utilizzo delle applicazioni tecnologiche e individuare nuovi metodi di valutazione della performance in alcuni sport acquatici. La prima parte (capitoli 1-5), si concentra sulla tecnologia prototipale chiamata E-kayak e le varie applicazioni nel kayak di velocità. In questi lavori è stata verificata l’attendibilità dei dati forniti dal sistema E-kayak con i sistemi presenti in letteratura. Inoltre, sono stati indagati nuovi parametri utili a comprendere il modello di prestazione del paddler. La seconda parte (capitolo 6), si riferisce all’analisi cinematica della spinta verticale del pallanuotista, attraverso l’utilizzo della video analisi 2D, per l’individuazione delle relazioni Forza-velocità e Potenza-velocità direttamente in acqua. Questo studio pilota, potrà fornire indicazioni utili al monitoraggio e condizionamento di forza e potenza da svolgere direttamente in acqua. Infine la terza parte (capitoli 7-8), si focalizza sull’individuazione della sequenza di Fibonacci (sequenza divina) nel nuoto a stile libero e a farfalla. I risultati di questi studi suggeriscono che il ritmo di nuotata tenuto durante le medie/lunghe distanze gioca un ruolo chiave. Inoltre, il livello di autosomiglianza (self-similarity) aumenta con la tecnica del nuoto.

Un nuovo catalogo dei manoscritti alchemici greci delle biblioteche italiane.

Il presente lavoro di ricerca propone una revisione del corpus greco dei manoscritti alchemici conservati presso le biblioteche italiane attraverso la realizzazione di un nuovo catalogo, aggiornato ed elaborato secondo le recenti norme di catalogazione. Tale progetto risponde alla necessità di un completo riesame dell’attuale catalogo dei codici alchemici italiani curato da Carlo Oreste Zuretti e pubblicato a Bruxelles nel 1927 (Catalogue des manuscrits alchimiques grecs, II). L’inadeguatezza e insufficienza di tale sussidio emerge soprattutto nella descrizione dei singoli esemplari, specie per quanto riguarda gli aspetti codicologici e paleografici. Il nuovo accurato studio che ha coinvolto ciascun manoscritto mira alla realizzazione di un esaustivo strumento di lavoro in grado di coniugare gli aspetti materiali, scrittori, testuali e storico-culturali degli esemplari esaminati. Le nuove acquisizioni emerse dallo studio dei codici consentono di delineare meglio la storia della circolazione dei testi alchemici greci e dei loro lettori.
