Résumé :

Industrial facilities and other sources can emit air pollutants from fugitive leaks, process malfunctions and area sources that can be difficult to understand and to manage. Next generation emissions measurement (NGEM) approaches executed near facilities are enabling new ways to assess these sources and their impacts to nearby populations. This paper describes complementary uses of emerging NGEM systems in a Louisville, KY industrial district (Rubbertown), focusing on an important area air toxic, 1,3-butadiene. Over a one-year deployment starting in September 2017, two-week average passive samplers (PSs) at 11 sites showed both geospatial and temporal trends. At 0.24 ppbv annual average 1,3-butadiene concentration, a group of PSs located near facility fence lines was elevated compared to a PS group located in the community and upwind from facilities (0.07 ppbv average). Two elevated PS periods capturing emission events were examined using time-resolved NGEM approaches as case studies. In one event a 1.18 ppbv PS reading was found to be relatively localized and was caused by a multiday emission from a yet to be identified, non-facility source. In the other event, the airshed was more broadly impacted with PS concentrations ranging from 0.71 ppbv for the near-facility group to 0.46 ppbv for the community group. This case was likely influenced by a known emission event at an industrial facility. For both case studies, air pollutant and wind data from prototype NGEM systems were combined with source location models to inform the emission events. This research illustrates the power of applying NGEM approaches to improve both the understanding of emissions near sources and knowledge of impacts to near-source communities.

Résumé :

Abstract Glioblastoma (GBM) is an aggressive primary brain tumor with a poor survival rate. One of the most common molecular alterations seen in GBM is amplification and/or mutation of the Epidermal Growth Factor Receptor (EGFR), which has made it an attractive therapeutic target. However, several EGFR tyrosine kinase inhibitors have been tested clinically in GBM with minimal success. One reason for this lack of efficacy could be due to acute, adaptive resistance via alternative pathway activation. To investigate this mechanism of tumor resistance, we used RNA-seq and multiplex inhibitor bead/mass spectrometry (MIB-MS) to analyze the transcriptomes and kinomes of genetically engineered murine astrocytes with common GBM genotypes. We have previously shown that 38% of the expressed kinome varied among a panel of diverse nGEM astrocytes harboring Cdkn2a deletion (C) plus Pten deletion (CP), wild-type human EGFR (CE) or EGFRvIII (CEv3) overexpression or both EGFRvIII overexpression and Pten deletion (CEv3P). Although CE have a similar transcriptional profile to C cells at baseline, when treated with the EGFR inhibitor afatinib, CE respond more similarly to CEv3 cells. When cells containing endogenous murine EGFR (C and CP) are treated with afatinib, fewer than 0.5% of kinases showed differential expression. In cells with EGFR overexpression alone, more than 6% of kinases were differentially expressed upon afatinib treatment, including Ntrk3, Fgfr2 and 3, Lyn, Bmx, Epha2 and 5, Fn3k, a kinase involved in fructosamine processing, and Nrbp2, a kinase involved in regulation of apoptosis. This effect was blunted in cells lacking Pten in addition to having EGFRvIII (CEv3P), resulting in less than 2% of kinases being differentially expressed. The only kinase upregulated in all three EGFR-overexpressing cell types was Coq8a, which is involved in electron transport and response to DNA damage. Given this overlap in response, Coq8a could be a potential dual treatment target for GBM.

Résumé :

The past two decades have seen dramatic changes of perspective and an explosion of new information in the broad fields covered by this overview. Within the constraints of space allowed it is not possible to cover all aspects or to mention all relevant publications. References to pre-1969 work have been kept to a minimum, except where dramatic revision of older views is now necessary.The traditional picture of the Roman frontier in Tripolitania owes an incalculable debt to the pioneering work of Richard Goodchild. Much of his observation remains of the highest value (accessible particularly through the volume of collected articles (edited by Joyce Reynolds), Goodchild 1976), but in the 40 years since his initial work on the limes Tripolitanus (1949a/b; 1950a/b; Ward-Perkins and Goodchild 1949) the available body of data has increased greatly and the conceptual framework for interpreting it has changed considerably (the scale of the reappraisal may be judged by comparing Brogan and Smith 1957 and 1985). The most controversial aspects of Goodchild's work concern the date of the development of a frontier in Tripolitania and the interpretation of the fortified farms which are so characteristic of the zone: ‘…no traces of a pre-Severan limes have yet been found. In this respect it may be significant that the linear fossata which Baradez has proved to constitute the central feature of the Numidian limes, and which he tentatively dated to the Hadrianic period, have not yet been found in the area of modern Tripolitania … Apart from … the outer fortresses of Gheriat el-Garbia and Bu Ngem … the military works of the limes Tripolitanus seem to have consisted almost exclusively of fortified farmhouses occupied by Libyan limitanei.’ (Goodchild 1950 = 1976, 44).

Résumé :

Teleseismic receiver functions (RFs) were used to investigate the seismic structure of the southern margin of the Dublin Basin, a potential geothermal site. Through an inversion-based approach, the elastic properties and seismic anisotropy of sedimentary basin units were examined, using data from a linear array of closely spaced seismic stations. Our results were compared with sonic logs and lithostratigraphies from two nearby boreholes, NGE1 and NGE2 and colocated active seismic data. Including a high-frequency RF (up to 8 Hz) allowed us to compute S-wave velocity models with a vertical resolution [Formula: see text]. The results indicated the presence of a subvertical lateral discontinuity in [Formula: see text], in correspondence with the main basin-bounding fault (Blackrock-Newcastle Fault [BNF]). North of this discontinuity, a shallow low-velocity layer thickens (from 0.7 to 1.0 km thick) toward the inner basin, in agreement with the geometry of the shallowest reflector found by active seismics. A good correlation was also found between the sonic log at NGE1 and our velocity model. Station DB02 showed an increase in [Formula: see text] at a depth of approximately 0.7 km and a decrease in [Formula: see text] at approximately 1.4 km in depth. Two velocity jumps with matching polarities were also observed in the NGE1 sonic log at the contact between the Upper and Lower Calp formations (positive jump, 688 m deep), and between a calcarenite and a sandstone layers (negative jump, 1337 m deep). Moreover, the main velocity contrasts in our model agree with the major lithostratigraphic boundaries inferred from borehole-drilled samples. Two juxtaposed anisotropic layers are identified close to the BNF. Directions of the slow axis of anisotropy are consistent with the borehole structural data. From these observations, the presence of aligned open cracks within the sandstones, possibly fluid-filled, was inferred up to a depth of 2.3 km in the vicinity of the BNF.

Résumé :

This thesis concerns the development of fast neutron instrumentation for beam diagnostic. Two kind of detectors have been developed. The first is a diamond detector for fast neutron measurements at the ChipIr beamline of the ISIS spallation neutron source (Didcot, UK). ISIS is a 50Hz-pulsed source in which neutrons are produced by 800 MeV protons interacting on a heavy metal target. The second is a Gas Electron Multiplier (GEM) detector developed for measurements of the neutron emission map in the deuterium beam prototype facility for the ITER fusion reactor under construction at the RFX site (Padova). Measurements of the so-called Single Event Effects (SEE) are the main application of the ChipIr beamline. SEEs are a potential threat to the robustness of integrated circuits featuring dimensions of tens of nanometers. SEEs occur when a highly energetic particle causes a disruption of the correct operation of an electronic component by striking its sensitive regions. Recent studies have shown that the neutron component above 1 MeV of the cosmic ray radiation is the primary contribution to SEEs for heights < 10 km. In order to evaluate the sensitivity of electronic devices to SEEs, fault-tolerant design techniques must be employed, and extensive analyses are needed to qualify their robustness. Experiments with atmospheric neutrons can be carried out but, due to the low intensity, they require very long periods of data acquisition. Neutron sources represent an opportunity due to the availability of high intensity fluxes which allow for accelerated irradiation experiments. Recent experiments performed at ISIS on the VESUVIO beamline demonstrated the suitability of ISIS for this kind of application. The new ChipIr beamline will provide an atmospheric-like neutron spectrum with a multiplication factor around 10^8. A crucial task for ChipIr design is the development of a neutron beam monitor for measurements of the neutron fluence in the MeV energy range. The detector developed in this thesis as a beam monitor for ChipIr is a Single-crystal Diamond Detector (SDD). Neutron detection using diamonds is based on the collection of the electrons/holes pairs produced by the energy deposited in the crystal following neutron reactions with carbon. First tests were performed in 2009 using a prototype SDD. The device features a p-type/intrinsic/metal Schottky barrier structure where the active (intrinsic) detection layer is obtained by chemical-vapour deposition. Both Time of Flight (ToF) only and biparametric (ToF and pulse height) measurements were successfully performed. Measurements were also performed using a Fission Diamond Detector (FDD). A FDD is a device based on a single crystal diamond coupled to a natural uranium converter foil. The biparametric data collection allowed us to distinguish events from 235U, 238U and from carbon break-up reactions inside the diamond. Limitations to quantitative analysis due to the initial choice of detector thickness and instrumental settings were highlighted by the tests. In a new set of experiments performed in July 2010, April 2011 and October 2011 a new fast neutron detector was tested. The measurements showed three characteristics regions in the biparametric spectra: -background events of low pulse heights induced by gamma-rays; -low pulse height events in the neutron ToF region corresponding to En in the range 2.4-5.7 MeV which are ascribed to elastic scattering on 12C; -large pulse height events in the ToF region corresponding to En>6 MeV which are ascribed to 12C(n,α)9Be and 12C(n,n')3α reactions. Neutron energy information was found to be contained both in the pulse height and in the ToF data, which suggests that SDDs are good candidate detectors for spectroscopy in fast neutron irradiation experiments. The use of diamond detectors as beam monitors requires further characterization of their response to monoenergetic neutrons. The second detector developed in this thesis is a nGEM detector able to map the neutron intensity produced in the SPIDER/MITICA beams at the Consorzio RFX in Padova. The ITER neutral beam test facility under construction in Padova will host two experimental devices: SPIDER, a 100 keV negative hydrogen/deuterium beam, and MITICA, a full scale, 1 MeV deuterium beam. A number of diagnostics will be deployed in the two facilities to qualify the beams. The aim of this thesis was to design a neutron diagnostic for SPIDER, as a first step towards the application of this diagnostic technique to MITICA. The proposed detection system is called CNESM which stands for Close-contact Neutron Emission Surface Mapping. CNESM is placed right behind the beam dump, as close as possible to the neutron emitting surface. It shall provide the map of the neutron emission on the surface of the beam dump. The latter is a rectangular panel made of water cooled pipes used to stop the incoming beam. The CNESM diagnostic system uses nGEM as neutron detectors. These are Gas Electron Multiplier detectors equipped with a cathode that also serves as neutron-proton converter. The diagnostic was designed on the basis of simulations of the different steps, from the deuteron beam interaction with the beam dump to the neutron detection in the nGEM. The deuteron deposition inside the dump was simulated with the TRIM code in order to provide the deposition profile. Neutron emission occurs via fusion reactions between the deuterium beam and the deuterons implanted in the beam dump surface. Neutron scattering in the beam dump was simulated using the MCNPX code. The nGEM cathode is at about 30 mm from the beam dump front surface. It is composed of two layers (polyethylene + aluminum) each ~50μm thick. The aluminum layer stops all protons that are emitted from the polyethylene at an angle higher than 40° relative to the normal to the cathode surface. This means that most of the detected neutrons at a point of the nGEM surface are emitted from the corresponding 40X22 mm^2 beamlet footprint on the dump front surface. The nGEM readout pads (area 20X22 mm^2) will record a useful count rate of ~5 kHz providing a time resolution of better than 1 s. Each nGEM detector maps the neutron emission from a group of 5X16 beamlets: as many as 16 nGEM detectors would be needed to cover the entire beam dump. The effect of the directional detector response due to the Al foil is to decrease the FWHM value to about 30 mm. This level of spatial resolution is adequate for unfolding the neutron source intensity from the 2D event map in the nGEM detector. The first nGEM detector prototype was tested at the FNG neutron source in Frascati, where the directional response of the nGEM cathode to neutrons was verified. The successful design of the CNESM neutron diagnostic for SPIDER provides the basis for its application to MITICA (X100 larger neutron fluxes expected), where it will be particularly useful to resolve the horizontal beam intensity profile.

Résumé :

This thesis explores how Katuic-speaking indigenous groups in the Central Annamitic Cordillera of Vietnam and Laos understand their environment – hills, streams and forest. Katuic eco-cosmology assumes that the natural landscape is imbued with spirit agents, with whom people must continuously communicate lest misfortune will strike and their livelihoods fail. The thesis posits the hypothesis that these spirit beliefs, and a variety of taboo notions accompanying them, can be interpreted as expressions of a complex socio-environmental adaptation. Today, the indigenous groups in the study region are confronted with a massive development- and modernisation push on two fronts – that of the global development industry on the one hand, and the implementation of national development policies and programs as part of the high-modernist state project in communist Vietnam and Laos, on the other. A second objective of the thesis, then, is to examine the effects of this multi-layered and multi-scaled confrontation on indigenous cosmology, livelihood and landscape. It is argued, this confrontation at the development frontier can be conceived of as an interface between different ontologies or reality posits – one animist, articulated in a relational stance towards the landscape; the other, a naturalist or rationalist ontology, expressed as an objectivist stance towards nature and embodied in the high-modernist development schemes and programs unfolding in the region with the aim of re-engineering its indigenous societies and exploiting its natural resources. Large parts of the Central Annamites were severely impacted by the Vietnam War; uncounted numbers of minority people were killed, or had their villages destroyed or relocated while defoliants, bombs, and forest fires ravaged the landscape. In the decades that followed the war, the entire social and natural landscape has been reshaped by national development policies and the modernist visions that underpin them. The thesis attempts to understand this physical and cultural transformation of the landscape, focusing particularly on the gradual breakdown of the complex indigenous socio-religious institutions that appear to have played an important functional role in maintaining the pre-war structure of the landscape. The thesis is based primarily on fieldwork carried out between 2004 and 2009 in the provinces of Quảng Nam and Thừa Thiên–Huế in Vietnam and Sekong in Laos.

Résumé :

Les Ngam-Ngam, les Tchokossi et les Moba-Gourma se sont implantés à Sansanne-Mango (Togo septentrional) à des époques différentes. Les Tchokossi organisés dans des structures politiques hiérarchisées et centralisées imposèrent vite, grâce à leur suprématie militaire, leur domination sur tous les autres peuples de la région. La principale conséquence de cette domination se traduisit dans l'espace par une forme d'occupation et d'utilisation du sol ayant des incidences sur la production agricole. Cela a permis, au regard d'une faible densité de peuplement, d'obtenir des rendements et une production suffisants pour satisfaire les besoins alimentaires des paysanneries. Mais, l'exode rural, la transformation de leur économie de subsistance en économie intégrée au système des échanges régionaux et internationaux, et plus particulièrement la réduction de l'espace de vie due à la création et à l'extension du parc national et de la réserve de chasse de la Keran ne sont-ils pas des facteurs de bouleversement des équilibres socio-économiques et politiques de ces paysanneries? À travers les exploitations agricoles considérées comme des unités de production et des cellules de vie, c'est l'étude de l'évolution de ces sociétés d'agriculteurs qui est mise en évidence. L'approche par les exploitations agricoles est une méthode d'analyse synthétique dans laquelle les facteurs diachroniques dont les dimensions démographique, sociale et économique des exploitations, les objectifs de production, et les systèmes de cultures sont les principaux axes autour desquels est centrée cette étude

Objectives: To compare the effects of retrograde rhinopharyngeal clearance (RRC) with nasopharyngeal aspiration in children admitted with acute viral bronchiolitis (AVB). Methods: This is an experimental, controlled and randomized study in children admitted for AVB up to 12 months old. Patients were divided in aspiration group (AG), submitted to nasopharyngeal aspiration, and clearance group (CG), submitted to RRC technique. In both groups there were three evaluations in the same day (C1, C2, C3), including cardiorespiratory parameters, clinical score of respiratory dysfunction and adverse effects. Results: 100 children were included, 50 in each group, with no statistical difference between the groups regarding the characteristics of the sample. There was a significant reduction in heart rate (HR) in C1 and C2 after 10 and 30 min. Number of episodes of nasal bleeding and vomiting was higher in AG compared to CG. Children classified as moderate showed a significant reduction of retractions and nasal bleeding. AG children?s showed an increase of 6.7% and 19.5% of wheezing and retractions, respectively, while the children of CG showed only 4.6% for both parameters. Conclusion: The use of RRC technique in the clinical management of children with AVB can be an alternative for the clearance of the upper airways, as it showed immediate positive results on the occurrence of complications and signs of respiratory effort compared with the nasopharyngeal aspiration. Children classified with moderate clinical scores appear to be the most benefited.
Objetivos: Comparar os efeitos da desobstru??o rinofar?ngea retr?grada (DRRI) com a aspira??o nasofar?ngea em crian?as internadas com diagn?stico de bronquiolite viral aguda. M?todos: Estudo do tipo experimental, controlado e randomizado, em crian?as internadas por BVA com at? 12 meses de idade. Os pacientes foram divididos em grupo aspira??o (GA), submetido ? aspira??o nasofar?ngea, e grupo desobstru??o (GD), submetido ? t?cnica de DRRI. Em ambos os grupos foram realizadas tr?s avalia??es, no mesmo dia (C1, C2, C3), incluindo par?metros cardiorrespirat?rios, escore cl?nico de disfun??o respirat?ria e presen?a de efeitos adversos. Resultados: Foram inclu?das 100 crian?as, sendo 50 em cada grupo, sem diferen?a estat?stica entre os grupos quanto ? caracteriza??o da amostra. Houve redu??o significativa da frequ?ncia card?aca (FC) na C1 e C2 ap?s 10 e 30 min. O n?mero de epis?dios de sangramento nasal e v?mito foi maior no GA em rela??o ao GD. Crian?as classificadas como moderadas apresentaram redu??o significativa de tiragem e sangramento nasal. Crian?as do GA apresentaram um aumento de 6,7% e 19,5% de sibil?ncia e tiragem, respectivamente, enquanto nas crian?as do GD foi de apenas 4,6% para ambos os par?metros. Conclus?o: A utiliza??o da t?cnica de DRRI no manejo cl?nico de crian?as com BVA pode ser uma alternativa para a desobstru??o de vias a?reas superiores, pois mostrou resultados imediatos positivos sobre a ocorr?ncia de complica??es e sinais de esfor?o ventilat?rio em compara??o com a aspira??o nasofar?ngea. Crian?as classificadas com escore cl?nico moderado parecem ser as mais beneficiadas.

Résumé :

The Navy and Marine Corps Intranet (NMCI), which is second only to the Internet in size, was supposed to be a mechanism to transform and support the Navy and Marine Corps with an IT infrastructure that would move the Department of Navy into the 21st century of warfare. Its function was to enhance command and control initiatives of the Navy and Marine Corps by harnessing the power of an integrated network. The current state of NMCI, though marred by a decade filled with marginal successes and many setbacks, is very positive, boasting more than 700,000 users, and consisting of over 380,000 work stations in more than 3,000 locations dispersed over seven continents. In 2008, Department of Navy leadership decided to move on and embrace the Next Generation Enterprise Network (NGEN) guided by early transition activities (ETA) and continuity of services contract. The use of the ETAs was to successfully mitigate the risk while migrating services from a contractor-owned, contractor-operated model to one that gives the government increased command and control. The purpose of this research is to examine the effectiveness of ETA and concurrent contracts in mitigating the challenges of migrating from the NMCI environment.

Syfte: Syftet är att undersöka om det finns ett samband mellan aktiers likviditet och avkastning. Metod: Vår studie består av en kvantitativ metod där vi med hjälp av databasen Eikon från Thomson Reuters samlat in finansiella data. Vi har sedan med hjälp av Excel sammanställt och gjort beräkningar och slutligen gjort korrelationstester i statistikprogrammet SPSS. Resultat och slutsats: Studien skiljer sig från tidigare forskningsresultat då ingen signifikant likviditetspremie kan fastställas vid årlig ombalansering av portföljerna. När portföljerna behåller samma aktier under hela tidsperioden (6 år) finner vi däremot att den minst likvida portföljen genererar betydligt högre avkastning jämfört med den mest likvida portföljen. Bidrag: Studiens teoretiska bidrag stärker tidigare forskningsresultat om att beta inte är ett komplett riskmått vad gäller illikvida aktier. Ingen likviditetspremie uppkommer då innehavsperioden är ett år men då vår innehavsperiod istället är sex år finner vi stora skillnader mellan vår minst respektive mest likvida portfölj. Studiens praktiska bidrag riktar sig till investerare och företagsledare. Investerare kan vid längre tidsperioder nyttja LM12 som en investeringsstrategi för att skapa en överavkastning och företagsledare kan undersöka nyttan med att öka likviditeten i företagets aktier för att sänka företagets WACC och därmed öka värdet på företaget. Förslag till vidare forskning: För att studera aktielikviditeten vidare skulle andra innehavsperioder (längre än ett år) för portföljerna kunna undersökas. Att undersöka längre tidsperioder för studien hade också varit intressant för att undersöka hur likviditetspremien varierar över tid.
Aim: The aim is to examine if there is a relationship between the liquidity and return of common stocks. Method: This study consists of quantitative research method in which we have collected financial data using the Eikon database from Thomson Reuters. We then compiled and made calculations using Excel and finally made correlation tests in the statistics program SPSS. Result and conclusion: The results from this study differs from previous research results since no significant liquidity premium could be determined while using annual rebalancing of the portfolios. When the portfolios held the same stocks for the entire period (6 years), we found that the least liquid portfolio generated significantly higher returns compared to the most liquid portfolio. Contribution of the thesis: The study's theoretical contribution strengthens previous research results in that beta is not a complete risk measure in terms of illiquid shares. No liquidity premium arises when the holding period is one year, but when our holding period is instead six years, we find great differences between our least and most liquid portfolio. The practical contribution of the study is aimed at investors and business leaders. Investors can use LM12 as an investment strategy to create an excess return during long holding periods, and business leaders can examine the benefits of increasing the liquidity of the company's common stock to lower the company's WACC and hence increase the value of the company. Suggestion for future research: In order to study the liquidity premium further, other holding periods (longer than one year) for the portfolios could be investigated. Investigating longer time periods for the study would also be interesting to investigate how the liquidity premium varies over time.

Résumé :

La presente tesi si pone l’obiettivo di approfondire due temi di ricerca. Il primo indaga se, a seguito delle riforme correlate al rafforzamento della governance economica europea conseguente alla crisi del 2008-2009, i poteri di spesa degli Stati membri, a partire da quello italiano, abbiano tuttora la possibilità di ottemperare agli obblighi di garanzia del nucleo inviolabile di diritti e libertà (e quindi del principio democratico). Il secondo discende dalla scelta, in risposta alla crisi economica del 2008-2009 ed economico-sanitaria del 2020, di approfondire il processo di integrazione europea esternalizzando parte degli strumenti serventi i poteri di spesa nazionali. Porta, quindi, l’indagine qui esposta a ricostruire il quadro giuridico della gestione delle finanze pubbliche dell’Uem. Ovvero, ad individuare e vagliare i singoli strumenti della governance economica europea e di concerto a domandarsi se questi siano in grado non tanto e non solo di ottemperare quantitativamente ai compiti affidati ai poteri di spesa nazionali, quanto se siano regolati da un sistema di pesi e contrappesi capace di veicolarne le risorse all’ottemperanza dei fini di eguaglianza sostanziale e partecipazione democratica. Su quest’ultimo punto si ricongiungono, dunque, i temi finora esplicitati, e affrontati separatamente lungo i primi capitoli della trattazione, manifestando il loro essere parte di un interrogativo unitario: possono le Costituzioni degli Stati membri (in particolare di Italia e Germania) coesistere con la cessione ad un potere di spesa europeo dell’assolvimento dei compiti di garanzia di diritti e libertà, e conseguentemente del principio democratico, senza che si incorra in una rottura costituzionale? A partire da Next Generation EU, infatti, sembra che la rotta per l’altra sponda dell’ormai famoso guado sia stata individuata nell’approfondimento della governance economica europea e nello strumento del debito. Tuttavia, tale percorso ha già portato alla forzatura dei limiti disposti dalle Costituzioni e dai Trattati fondamentali dell’Ue, sia secondo la giurisprudenza che la dottrina costituzionale di molti tra gli Stati membri. Diversamente dalla rotta del ricorso al debito si ritiene che scegliere quella del rafforzamento, quantitativo e qualitativo, del sistema fiscale dell’Ue possa evitare di accrescere le probabilità dell’avverarsi della rottura precedentemente paventata senza esigere necessariamente una previa riforma complessiva dei Trattati fondamentali.
This PhD Thesis explores whether the Constitutions of the Member States of the European Union, in particular that of Italy and Germany, can coexist with the transfer a) of the tasks of guaranteeing social rights and b) of democratic control over the spending power, to a centralized European spending power without leading to a constitutional break. It does so through the study of two key issues. The first one is whether, following the reforms related to European economic governance implemented as a consequence of the 2008-2009 crisis, national spending powers, significantly the Italian one, still have the chance to comply with their obligations to guarantee the inalienable core of fundamental rights and freedoms and therefore of the democratic principle. The second issue considered is the response given to the economic crisis of 2008-2009 and to economic-health crisis of 2020, which is furthering the process of European integration by outsourcing part of the instruments serving national spending powers. Therefore, this PhD Thesis reconstructs the legal framework of the management of public finances of the EMU, identifying and studying the individual instruments of European economic governance. It then explores whether these are able not only to comply quantitatively with the tasks originally entrusted to national spending powers, but also if they are regulated by a system of checks and balances capable of channeling those resources to the fulfillment of the aims of substantial equality and democratic participation. Starting from Next Generation EU, hitherto the route to the other side of the river crossing has been identified in the strengthening of European economic governance via the debt instrument. However, this process has already led to testing the limits laid down by Constitutions and fundamental EU Treaties according to jurisprudence and constitutional doctrine of many of the Member States. Instead of following the debt route, this Thesis argues that it is through strengthening the EU fiscal system that the possibility of the rupture outlined above can be avoided without needing a comprehensive reform of the founding Treaties of the European Union.

Résumé :

Con questo libro curato da Dario Collini, che raccoglie il lavoro di giovani ricercatori guidati da Anna Dolfi («GREM» «NGEM») che si sono occupati dei 17.000 pezzi epistolari del Fondo Macrì, si offre uno straordinario strumento di lavoro a chi si interessa di Ermetismo, di critica e poesia del Novecento italiano. Ombre dal fondo o ‘luci intermittenti’ che siano, i bagliori mandati dagli epistolari sono segni della genesi umana della cultura, visto che conservano traccia di quanto è legato al quotidiano che contribuisce alla costruzione della ‘grande’ storia e della progettualità; intellettuale e politica che l’accompagna. Ecco allora che letture, libri, riviste, collaborazioni, amicizie, risentimenti, viaggi, passioni letterarie e private emergono da questi regesti, a dare voce a un’epoca e ai suoi protagonisti.

Résumé :

La Unión Europea ha dado respuesta a la crisis climática, la COVID-19, la erosión de la globalización, y un entorno internacional adverso a través de tres estrategias interrelacionadas: el Pacto Verde Europeo, que define un nuevo modelo de desarrollo económico y social orientado a la descarbonización de la economía y el cumplimiento de las metas climáticas del Acuerdo de París; el programa NextGenerationEU (NGEU), como respuesta contracíclica a la pandemia, y mecanismo financiero para acelerar la triple transición socioeconómica, digital y ecológica de la UE; y la búsqueda de una mayor soberanía o autonomía estratégica. Este trabajo examina NGEU y el Pacto Verde como elementos del relanzamiento del proyecto europeo, y de la respuesta societal de la UE a la crisis de la globalización. También se analiza cómo la invasión rusa en Ucrania ha inducido la convergencia de las metas del Pacto Verde en materia de energía con los imperativos de soberanía energética planteados por la aparición de una “Europa geopolítica”.

Texte intégral

Résumé :

This paper introduces a sectoral model for the Spanish economy that allows a better understanding of the propagation of sector-specific shocks taking into account different network interdependencies. In particular, the model features sector interactions along several dimensions in an open economy setting, either in the provision of intermediate inputs and capital goods or competing in the labour market. This framework is flexible enough to provide insights into the effect of several policy-relevant shocks, such as global value chain bottlenecks, increases in production costs in energy-intensive sectors or large public investment programmes. In order to illustrate the role of such sectoral interactions, we consider a sectorisation of Next Generation EU (NGEU) funds based on Spain’s Recovery, Transformation and Resilience Plan (RTRP) which will mobilize €69.5 bn in grants. According to our findings, the average impact over a 5-year horizon is 1.15% of GDP if we consider only the direct effect of the investment programmes and expenditure plans, but it increases to 1.75% if we take into account the increase in the productive capacity of certain sectors and its propagation through the production network. Moreover, the resulting expansion is particularly strong in sectors highly dependent on high-skilled labour, such as IT and professional services, which might lead to shortages of high-skilled workers, reducing the aggregate impact on GDP by 25%.

Résumé :

MAGIC is the joint NASA/ESA constellation concept based on NASA’s Mass Change Designated Observable (MCDO) and ESA’s Next Generation Gravity Missions (NGGM) studies. The main objective of MAGIC is to extend the mass transport time series of previous gravity missions such as GRACE and GRACE-FO with significantly enhanced accuracy, spatial and temporal resolutions and to demonstrate the operational capabilities of MAGIC with the goal of answering global user community needs to the greatest possible extent. This document defines unambiguous and traceable requirements for preparing and developing MAGIC. The scope of the MAGIC Mission Requirement Document includes end-to-end Earth observation system including user/scientific requirements, mission operations, data product development and processing, data distribution and data archiving. The intention of the document is also to accommodate results from NASA MCDO study, ESA Phase-0 NGGM and other national studies on future gravity missions. The MAGIC MRD is a NASA/ESA reference document frozen in its current version 1.0 that defines the mission requirements achievable by an optimised two-pair Bender-type constellation of a future implementation. Subsequent ESA and NASA official documents of updated implementation baseline will be traceable to the MAGIC MRD.
