An instrumental analysis of the European Union's capability to act in conflict response

Descripció i anàlisi dels instruments polítics, econòmics, civils i militars de la Unió Europea per enfrontar qualsevol conflicte.

Los Pioneros del cooperativismo agrario de crédito español (1880-1920)

En las dos últimas décadas del siglo XIX en España el cooperativismo de crédito orientado hacia los pequeños productores agrícolas estuvo bastante ligado a las corrientes del “Regeneracionismo conservador” y el catolicismo social. Hemos estudiado las aportaciones de dos autores: Joaquín Díaz de Rábago y Nicolás Fontes. Díaz de Rábago contó con una fuerte formación teórica y colaboró en la redacción de un proyecto de ley sobre cooperativas, pero a pesar de su influencia no consiguió potenciar ninguna actividad concreta. Nicolás Fontes representa al hombre “práctico”. Sus circunstancias personales, era un importante terrateniente, lo animaron a poner en práctica un sistema de crédito destinado a ayudar a los pequeños arrendatarios. El modelo que puso en práctica se inspiraba en el Raiffeisen System, el mismo que defendía por Rábago. El desconocimiento mutuo de sus actuaciones invita a reflexionar sobre las limitaciones en la difusión del cooperativismo agrícola de crédito en España.

Scheduled service versus personal transportation: the role of distance

This paper analyzes both theoretically and empirically the relationship between distance and frequency of scheduled transportation services. We study the interaction between a monopoly firm providing high-speed scheduled service and personal trans- portation (i.e., car). Most interestingly, the carrier chooses to increase frequency of service on longer routes when competing with personal transportation because provid- ing a higher frequency (at extra cost) it can also charge higher fares that can boost its profits. However, when driving is not a relevant option, frequency of service de- creases for longer flights consistently with prior studies. An empirical application of our analysis to the European airline industry con?rms the predictions of our theoretical model.

Scheduled Service Versus Personal Transportation: The Role of Distance

This paper presents a theoretical and empirical analysis of the relationship be- tween frequency of scheduled transportation services and their substitutability with personal transportation (using distance as a proxy). We study the interaction between a monopoly firm providing a high-speed scheduled service and private transportation (i.e., car). Interestingly, the carrier chooses to increase the frequency of service on longer routes when competing with personal transportation because by providing higher frequency (at extra cost) it can also charge higher fares which can boost its profits. However, in line with the results of earlier studies, frequency decreases for longer flights when driving is not a viable option. An empirical application of our analysis to the European airline industry confirms the predictions of our theoretical model.

An Instrumental analysis of the European Union´s capability to act in conflict response

Since its origins, the European Union has striven to be an actor on the International scene and a place in conflict Management. Yet the EU’s lack of activity cannot be justified by a mere lack of capacities. The EU counts with numerous political, economic, and, since 2003, civil and military instruments that should allow it to precede a comprehensive conflict response. This publication consists of a description of these instruments and an analysis of the final use that the Union makes of them in the different stages of a conflict. Examples will show us the EU’s main weakness in providing a comprehensive and timely response when a conflict breaks out.

Transportation choices and the value of statistical life

This paper exploits an unusual transportation setting to estimate the value of a statistical life(VSL). We estimate the trade-offs individuals are willing to make between mortality risk andcost as they travel to and from the international airport in Sierra Leone (which is separated fromthe capital Freetown by a body of water). Travelers choose from among multiple transportoptions ? namely, ferry, helicopter, hovercraft, and water taxi. The setting and original datasetallow us to address some typical omitted variable concerns in order to generate some of the firstrevealed preference VSL estimates from Africa. The data also allows us to compare VSLestimates for travelers from 56 countries, including 20 African and 36 non-African countries, allfacing the same choice situation. The average VSL estimate for African travelers in the sample isUS$577,000 compared to US$924,000 for non-Africans. Individual characteristics, particularlyjob earnings, can largely account for the difference between Africans and non-Africans; Africansin the sample typically earn somewhat less. There is little evidence that individual VSL estimatesare driven by a lack of information, predicted life expectancy, or cultural norms around risktakingor fatalism. The data implies an income elasticity of the VSL of 1.77. These revealedpreference VSL estimates from a developing country fill an important gap in the existingliterature, and can be used for a variety of public policy purposes, including in current debateswithin Sierra Leone regarding the desirability of constructing new transportation infrastructure.

Crisis de las solidaridades tradicionales y nuevas formas de asociación y resistencia campesina en la Cataluña occidental (1750-1920)

El objeto de este estudio es el análisis de las solidaridades campesinas y de su crisis en la etapa final del Antiguo Régimen. A través de la Cofradía de Labradores - que, en el siglo XVIII, representaba de hecho a la mayor parte del campesinado de Lleida -, se analiza la defensa de los comunales y la lucha contra el diezmo. Estos conflictos en el fondo traducen las dificultades del pequeño campesinado de Lleida para obtener los ingresos necesarios para reproducir la unidad familiar. Se estudian las dos vías - la campesina y la de los hacendados - de desarrollo social y económico en relación con la propiedad de la tierra en la etapa de reforma liberal. Ante el fracaso de la "vía campesina", se estudia el origen del asociacionismo tanto el impulsado por el pequeño campesinado -a través de sociedades de socorros mutuos en un primer momento- como aquél que tiene como objetivo la introducción de mejoras técnico-productivas. Como en el resto de Cataluña, en la parte occidental llana se desarrollarán estas experiencias de manera más intensa en el marco de la crisis finisecular y etapa posterior.

Lipid rafts act as specialised domains for tetanus toxin binding and internalisation in neurons

Tetanus (TeNT) is a zinc protease that blocks neurotransmission by cleaving the synaptic protein vesicle-associated membrane protein/synaptobrevin. Although its intracellular catalytic activity is well established, the mechanism by which this neurotoxin interacts with the neuronal surface is not known. In this study, we characterize p15s, the first plasma membrane TeNT binding proteins and we show that they are glycosylphosphatidylinositol-anchored glycoproteins in nerve growth factor (NGF)-differentiated PC12 cells, spinal cord cells, and purified motor neurons. We identify p15 as neuronal Thy-1 in NGF-differentiated PC12 cells. Fluorescence lifetime imaging microscopy measurements confirm the close association of the binding domain of TeNT and Thy-1 at the plasma membrane. We find that TeNT is recruited to detergent-insoluble lipid microdomains on the surface of neuronal cells. Finally, we show that cholesterol depletion affects a raft subpool and blocks the internalization and intracellular activity of the toxin. Our results indicate that TeNT interacts with target cells by binding to lipid rafts and that cholesterol is required for TeNT internalization and/or trafficking in neurons.

Cardiovascular mechanisms of death in severe COPD exacerbation: time to think and act beyond guidelines.

Three important studies on acute exacerbations of chronic obstructive pulmonary disease (ECOPD)have been published in Thorax. Two of them, by Chang et al1(see page 764) and Hoiset et al2 (see page 775), show the importance of the cardiac biomarkers troponin T and NT-BNP (Nterminal pro-B-type natriuretic peptide) as strong predictors of the increased risk of death of patients hospitalised because of ECOPD.1 2.....

Privatization and PPPS in transportation infrastructure: Network effects of increasing user fees

PPPS: Problem: Public-private-partnerships in transport infrastructure characteristically increase user-fees. Purpose: We aim to identify the network effects of the use of PPPs and increased user tolls in road infrastructure. Methods: We study the increases in user tolls on motorways due to the use of PPPs in the US. Results and conclusions: Among other things, the monetization of motorways is associated with an increase in toll levels that has consequences for their users, and also for the rest of the sections of the network.

Infrastructure and nation building: The regulation and financing of network transportation infrastructures in Spain (1720-2010)

This paper analyzes Spanish infrastructure policy since the early 1700s: Road building in the eighteenth century, railway creation and expansion in the nineteenth, motorway expansion in the twentieth, and high speed rail development in the twenty-first. The analysis reveals a long-term pattern, in which infrastructure policy in Spain has been driven not by the requirements of commerce and economic activity, but rather by the desire to centralize transportation around the country’s political capital.

Traducció i adopció a l'Índia: Hindu Adoptions And Maintenance Act, 1956

L’objectiu principal d’aquest treball de fi de grau és fer-se càrrec d’una traducció jurídica amb tot el què això implica: documentar-se a través de fonts fiables, emprar les eines adequades, lliurar-lo dins el termini establert, entre d’altres. En aquest cas, és una traducció de les lleis que regulen les adopcions a l’Índia. A més, en aquest treball també s’explica breument el dret civil a Catalunya i es compara amb el de l’Índia, ja que es basen en idees molt diferents. Aquests tipus de traduccions exigeixen precisió i claredat perquè els conceptes i les estructures sintàctiques acostumen a ser molt complexes. A continuació, hi ha detallat cada pas que s’ha seguit per tal d’assolir l’objectiu principal.
