400 anos do De Legibus de Francisco SUAREZ (1548-1617)

O artigo destaca a importância da contribuição de Francisco SUAREZ (1548- 1617) para a evolução do direito internacional, com ênfase nas questões práticas que este teve de enfrentar para formular soluções legais – o dado central da obra é a afirmação da unidade intrínseca da humanidade, em comunidade internacional formando um todo, apesar de dividida em povos e reinos. Observa o caráter de continuidade histórica entre o legado medieval e o Direito Internacional moderno, do qual o tratado Das leis e Deus legislador (1612) foi marco relevante.

Universal behavior of the Shannon mutual information of critical quantum chains

We consider the Shannon mutual information of subsystems of critical quantum chains in their ground states. Our results indicate a universal leading behavior for large subsystem sizes. Moreover, as happens with the entanglement entropy, its finite-size behavior yields the conformal anomaly c of the underlying conformal field theory governing the long-distance physics of the quantum chain. We study analytically a chain of coupled harmonic oscillators and numerically the Q-state Potts models (Q = 2, 3, and 4), the XXZ quantum chain, and the spin-1 Fateev-Zamolodchikov model. The Shannon mutual information is a quantity easily computed, and our results indicate that for relatively small lattice sizes, its finite-size behavior already detects the universality class of quantum critical behavior.

La protezione dei diritti sociali nell'ordinamento dell'Unione Europea

This study deals with the protection of social rights in Europe and aims to outline the position currently held by these rights in the EU law. The first two chapters provide an overview of the regulatory framework in which the social rights lie, through the reorganisation of international sources. In particular the international instruments of protection of social rights are taken into account, both at the universal level, due to the activity of the United Nations Organisation and of its specialized agency, the International Labour Organization, and at a regional level, related to the activity of the Council of Europe. Finally an analysis of sources concludes with the reconstruction of the stages of the recognition of social rights in the EU. The second chapter describes the path followed by social rights in the EU: it examines the founding Treaties and subsequent amendments, the Charter of Fundamental Social Rights of Workers of 1989 and, in particularly, the Charter of Fundamental Rights of the European Union, the legal status of which was recently treated as the primary law by the Treaty of Lisbon signed in December 2007. The third chapter is, then, focused on the analysis of the substantive aspects of the recognition of the rights made by the EU: it provides a framework of the content and scope of the rights accepted in the Community law by the Charter of Fundamental Rights, which is an important contribution to the location of the social rights among the fundamental and indivisible rights of the person. In the last section of the work, attention is focused on the two profiles of effectiveness and justiciability of social rights, in order to understand the practical implications of the gradual creation of a system of protection of these rights at Community level. Under the first profile, the discussion is focused on the effectiveness in the general context of the mechanisms of implementation of the “second generation” rights, with particular attention to the new instruments and actors of social Europe and the effect of the procedures of soft law. Second part of chapter four, finally, deals with the judicial protection of rights in question. The limits of the jurisprudence of the European Union Court of Justice are more obvious exactly in the field of social rights, due to the gap between social rights and other fundamental rights. While, in fact, the Community Court ensures the maximum level of protection to human rights and fundamental freedoms, social rights are often degraded into mere aspirations of EU institutions and its Member States. That is, the sources in the social field (European Social Charter and Community Charter) represent only the base for interpretation and application of social provisions of secondary legislation, unlike the ECHR, which is considered by the Court part of Community law. Moreover, the Court of Justice is in the middle of the difficult comparison between social values and market rules, of which it considers the need to make a balance: despite hesitancy to recognise the juridical character of social rights, the need of protection of social interests has justified, indeed, certain restrictions to the free movement of goods, freedom to provide services or to Community competition law. The road towards the recognition and the full protection of social rights in the European Union law appears, however, still long and hard, as shown by the recent judgments Laval and Viking, in which the Community court, while enhancing the Nice Charter, has not given priority to fundamental social rights, giving them the role of limits (proportionate and justified) of economic freedoms.

El modelo legal de retribución del administrador concursal

[ES] La situación de crisis económica actual ha hecho aflorar y convertir en exigencias latentes, situaciones que antaño se daban en nuestro ámbito jurídico con carácter esporádico. En esta cadena económica son tan importantes las entidades que inyectan capital al mercado, como el consumidor en sentido estricto, es por ello, que resulta imprescindible que cualquier medida que se adopte en todos los ámbitos tendentes a mejorar esta situación actual, no pierda de vista esta realidad que la práctica ha constatado.

Sviluppo di metodologie di localizzazione nel contesto del Comprehensive Nuclear Test-Ban Treaty

Since the first underground nuclear explosion, carried out in 1958, the analysis of seismic signals generated by these sources has allowed seismologists to refine the travel times of seismic waves through the Earth and to verify the accuracy of the location algorithms (the ground truth for these sources was often known). Long international negotiates have been devoted to limit the proliferation and testing of nuclear weapons. In particular the Treaty for the comprehensive nuclear test ban (CTBT), was opened to signatures in 1996, though, even if it has been signed by 178 States, has not yet entered into force, The Treaty underlines the fundamental role of the seismological observations to verify its compliance, by detecting and locating seismic events, and identifying the nature of their sources. A precise definition of the hypocentral parameters represents the first step to discriminate whether a given seismic event is natural or not. In case that a specific event is retained suspicious by the majority of the State Parties, the Treaty contains provisions for conducting an on-site inspection (OSI) in the area surrounding the epicenter of the event, located through the International Monitoring System (IMS) of the CTBT Organization. An OSI is supposed to include the use of passive seismic techniques in the area of the suspected clandestine underground nuclear test. In fact, high quality seismological systems are thought to be capable to detect and locate very weak aftershocks triggered by underground nuclear explosions in the first days or weeks following the test. This PhD thesis deals with the development of two different seismic location techniques: the first one, known as the double difference joint hypocenter determination (DDJHD) technique, is aimed at locating closely spaced events at a global scale. The locations obtained by this method are characterized by a high relative accuracy, although the absolute location of the whole cluster remains uncertain. We eliminate this problem introducing a priori information: the known location of a selected event. The second technique concerns the reliable estimates of back azimuth and apparent velocity of seismic waves from local events of very low magnitude recorded by a trypartite array at a very local scale. For the two above-mentioned techniques, we have used the crosscorrelation technique among digital waveforms in order to minimize the errors linked with incorrect phase picking. The cross-correlation method relies on the similarity between waveforms of a pair of events at the same station, at the global scale, and on the similarity between waveforms of the same event at two different sensors of the try-partite array, at the local scale. After preliminary tests on the reliability of our location techniques based on simulations, we have applied both methodologies to real seismic events. The DDJHD technique has been applied to a seismic sequence occurred in the Turkey-Iran border region, using the data recorded by the IMS. At the beginning, the algorithm was applied to the differences among the original arrival times of the P phases, so the cross-correlation was not used. We have obtained that the relevant geometrical spreading, noticeable in the standard locations (namely the locations produced by the analysts of the International Data Center (IDC) of the CTBT Organization, assumed as our reference), has been considerably reduced by the application of our technique. This is what we expected, since the methodology has been applied to a sequence of events for which we can suppose a real closeness among the hypocenters, belonging to the same seismic structure. Our results point out the main advantage of this methodology: the systematic errors affecting the arrival times have been removed or at least reduced. The introduction of the cross-correlation has not brought evident improvements to our results: the two sets of locations (without and with the application of the cross-correlation technique) are very similar to each other. This can be commented saying that the use of the crosscorrelation has not substantially improved the precision of the manual pickings. Probably the pickings reported by the IDC are good enough to make the random picking error less important than the systematic error on travel times. As a further justification for the scarce quality of the results given by the cross-correlation, it should be remarked that the events included in our data set don’t have generally a good signal to noise ratio (SNR): the selected sequence is composed of weak events ( magnitude 4 or smaller) and the signals are strongly attenuated because of the large distance between the stations and the hypocentral area. In the local scale, in addition to the cross-correlation, we have performed a signal interpolation in order to improve the time resolution. The algorithm so developed has been applied to the data collected during an experiment carried out in Israel between 1998 and 1999. The results pointed out the following relevant conclusions: a) it is necessary to correlate waveform segments corresponding to the same seismic phases; b) it is not essential to select the exact first arrivals; and c) relevant information can be also obtained from the maximum amplitude wavelet of the waveforms (particularly in bad SNR conditions). Another remarkable point of our procedure is that its application doesn’t demand a long time to process the data, and therefore the user can immediately check the results. During a field survey, such feature will make possible a quasi real-time check allowing the immediate optimization of the array geometry, if so suggested by the results at an early stage.

Equine and human mutual welfare: a whole subject? Critical aspects and possible strategies in equine-assisted activities and therapies

General aim of the study is equine welfare, particularly concerning different husbandry methodic and inter-specific relational factors. Specific aim is the evaluation of possible mutual (to humans and to equines) benefits and the analysis of critical factors/strength points, of human-horse relationship within Therapeutic Riding context (TR). The peculiarities of human-horse relationship (compared to the bond with “Pet”) are analyzed, concerning their socio-anthropological, psychological, psycho-dynamic distinctive characteristics. 8 European representative therapeutic riding centers (TRC) were therefore selected (on the basis of their different animals’ husbandry criteria, and of the different rehabilitative methodologies adopted). TRC were investigated through 2 different questionnaires, specifically settled to access objective/subjective animal welfare parameters; the quality of human-horse relationship; technicians’ emotional experienced. 3 Centers were further selected, and behavioral (145 hours of behavioral recording) and physiological parameters (heart rate and heart rate variability) were evaluated, aimed to access equine welfare and horses’ adaptive responses/coping (towards general environment and towards TR job). Moreover a specific “handling-task” was ideated and experimented, aimed to measure the quality of TR technicians-horses relationship. We did therefore evaluate both the individual horses’ responses and the possible differences among Centers. Data collected highlight the lack of univocal standardized methodic, concerning the general animals’ management and the specific methodologies (aimed to improve animal welfare and to empower TR efficacy). Some positive and some critical aspects were detected concerning TR personnel-horse relationship. Another experimental approach did evaluate the efficacy (concerning the mutual benefits’ empowerment) of an “ethologically-fitted” TR intervention, aimed to educate children to and through the relationship with horses. Our data evidenced that the improvement of human horse relationship, through structured educational programs for TR personnel might have important consequences both to human and equine welfare.

La giustiziabilità dei diritti sociali nell'ordinamento dell'Unione europea

L’oggetto del lavoro si sostanzia nella verifica del grado di giustiziabilità che i diritti sociali ricevono nell’ordinamento dell’Unione europea. L’indagine si articola in tre capitoli. Il primo è dedicato ad una sintetica ricostruzione dei modelli di welfare state riconosciuti dagli ordinamenti dei diversi paesi membri dell’Unione attraverso cui, la candidata enuclea un insieme di diritti sociali che ricevono tutela in tutti gli ordinamenti nazionali. L’esposizione prosegue, con la ricostruzione dell’evoluzione dei Trattati istitutivi dell’Unione e l’inclusione della sfera sociale tra gli obiettivi di questa. In particolare, il secondo capitolo esamina la giurisprudenza della Corte di Giustizia in relazione alle materie sociali, nonché l’inclusione dei diritti sociali nel testo della Carta dei diritti fondamentali. L’analisi si sofferma sulle tecniche normative adottate nell’area della politica sociale, evidenziando la tendenza ad un approccio di tipo “soft” piuttosto che attraverso il classico metodo comunitario. Esaurita questa analisi il terzo capitolo analizza i rapporti tra il diritto dell’Ue e quello della CEDU in materia di diritti sociali, evidenziano il diverso approccio utilizzato dalle due istanze sovranazionali nella tutela di questi diritti. Sulla base del lavoro svolto si conclude per una sostanziale mancanza di giustiziabilità dei diritti sociali in ambito dell’Unione. In particolare i punti deboli dell’Europa sociale vengono individuati in: un approccio regolativo alla dimensione sociale di tipo sempre più soft; la permanenza di alcuni deficit di competenze; la mancata indicazione di criteri di bilanciamento tra diritti sociali e libertà economiche e dalla compresenza delle due nozioni di economia sociale e di economia di mercato. Le conclusioni mostrano come l’assenza di competenze esclusive dell’Unione in materia di politica sociale non consenta una uniformazione/armonizzazione delle politiche sociali interne, che si riflette nell’incapacità dei modelli sociali nazionali di assorbire i grandi mutamenti macro economici che si sono avuti negli ultimi vent’anni, sia a livello sovranazionale che internazionale.

Controlled foreign companies (CFC) e delocalizzazione delle attività economiche nel diritto interno e nell'ordinamento europeo

Le ragioni della delocalizzazione sono molteplici e di differente natura. Si delocalizza, in primo luogo, per ragioni di stampo economico, finanziario eccetera, ma questa spinta naturale alla delocalizzazione è controbilanciata, sul piano strettamente tributario, dall’esigenza di preservare il gettito e da quella di controllare la genuinità della delocalizzazione medesima. E’ dunque sul rapporto tra “spinte delocalizzative” dell’impresa, da un lato, ed esigenze “conservative” del gettito pubblico, dall’altro, che si intende incentrare il presente lavoro. Ciò alla luce del fatto che gli strumenti messi in campo dallo Stato al fine di contrastare la delocalizzazione (più o meno) artificiosa delle attività economiche devono fare i conti con i principi comunitari introdotti con il Trattato di Roma e tratteggiati negli anni dalla giurisprudenza della Corte di Giustizia. In quest’ottica, la disciplina delle CFC costituisce un ottimo punto di partenza per guardare ai fenomeni di produzione transnazionale della ricchezza e agli schemi di ordine normativo preposti alla tassazione di codesta ricchezza. Ed infatti, le norme sulle CFC non fanno altro che omogeneizzare un sistema che, altrimenti, sarebbe lasciato alla libera iniziativa degli uffici fiscali. Tale “normalizzazione”, peraltro, giustifica le esigenze di apertura che sono incanalate nella disciplina degli interpelli disapplicativi. Con specifico riferimento alla normativa CFC, assumono particolare rilievo la libertà di stabilimento ed il principio di proporzionalità anche nella prospettiva del divieto di abuso del diritto. L’analisi dunque verterà sulla normativa CFC italiana con l’intento di comprendere se codesta normativa, nelle sue diverse sfaccettature, possa determinare situazioni di contrasto con i principi comunitari. Ciò anche alla luce delle recenti modifiche introdotte dal legislatore con il d.l. 78/2009 in un quadro normativo sempre più orientato a combattere le delocalizzazioni meramente fittizie.
