Essays On European Natural Gas Market
2018
La presente tesis ha cubierto diferentes aspectos de los mercados europeos del gas natural y la electricidad, en particular algunas propiedades que afectan a la efectividad de la cobertura, como la estacionalidad en varianza y en precios. Asimismo, se ha realizado un estudio de la prima de riesgo del gas natural, su relación con las variables de riesgo y su descomposición en una prima de riesgo de reinversión o ‘rollover’ y una prima de ‘preferencia por liquidez’ relacionada con el plazo. La tesis se compone de tres capítulos: el Capítulo I estudia la estacionalidad en los precios y la volatilidad y cómo mejora la efectividad de la cobertura teniendo en cuenta dicha estacionalidad; el Capít…
Imaging-guided interventions modulating portal venous flow: Evidence and controversies
2021
Portal hypertension is defined by an increase in the portosystemic venous gradient. In most cases, increased resistance to portal blood flow is the initial cause of elevated portal pressure. More than 90% of cases of portal hypertension are estimated to be due to advanced chronic liver disease or cirrhosis. Transjugular intrahepatic portosystemic shunts, a non-pharmacological treatment for portal hypertension, involve the placement of a stent between the portal vein and the hepatic vein or inferior vena cava which helps bypass hepatic resistance. Portal hypertension may also be a result of extrahepatic portal vein thrombosis or compression. In these cases, percutaneous portal vein recanalis…
GARCH models with changes in variance: An approximation to risk measurements
2003
This study aims to model volatility as an approximation to an optimum measurement of stock market risk because of the importance of this concept for, among other things, the proper management of portfolios. Following the proposal of Lamoureux and Lastrapes (1990), the authors consider that the high degree of persistence detected in GARCH models arises from a poor specification of the equation of the variance due to not considering the possible deterministic changes in the unconditional variance of the financial series. To determine the point in time as well as the duration of these changes, the proposal made by Inclan and Tiao (1994) is used. As an empirical application, whether or not the …
Assessing Master Students' Competencies Using Rubrics: Lessons Learned from Future Secondary Education Teachers
2020
The aim of this paper is to provide insights into the appropriateness of teaching-learning and evaluation processes using rubrics, for student self-assessments. We studied students enrolled on the Master&rsquo
Young Lads and Old Tars: Changing Age Structure of the Nordic Sailors, 1750s–1930s
2022
AbstractThis article analyzes the changing age structure of Swedish and Finnish sailors for almost 200 years. We show that the proportion of the youngest men increased during the age of sail (i.e., the older technology). The average age increased significantly during the early twentieth century as steam (i.e., the newer technology) replaced sail in Nordic shipping. Thus, a technological revolution did not displace the older workers, but rather diminished the demand for the younger ones. This study shows, however, that technological changes were not the only drivers of changes in the age structure of Nordic sailors. Institutional and societal changes also played an important role, though the…
Photo Use While Dating: From Forecasted Photos In Tinder To Creating Copresence Using Other Media
2019
While studying Finnish users of the online dating app Tinder searching for long- term partnerships, we paid attention to the importance of photos in their social interactions. Based on our study, we argue that photos play an important role in online dating. Initially, photos are chosen and uploaded to influence future interactions, particularly regarding who will contact them via their profile. We term this particular future tense of photography forecasted photos. Second, photos enabled the creation of copresence between dates, especially via instant messaging services instantly after capture. Third, the classic notions of photos depicting the past became important when wanting to be remind…
Give us today our daily bread: The effect of hunger on consumers’ visual attention towards bread and the role of time orientation
2021
Abstract This study investigated the effect of hunger on consumers’ visual attention during a food choice task, and the role of time orientation (i.e., present and future orientation) in this interplay. A lab-based eye-tracking experiment including 102 participants was conducted, with hunger as the manipulated factor (hungry, satiated). Participants in the satiated condition were served a breakfast buffet before the experimental tasks, whereas participants in the hungry condition were served the buffet after completion of the tasks. Both groups were exposed to a set of planograms depicting supermarket shelves and were asked to choose an option they could consider buying, while their eye mov…
OSCURITÀ E FUTURO DEL SOGGETTO
2018
This paper analyses the topic of subjectivity within Husserl's phenomenology, specifically focusing on its temporal structure. The dimension of future and its relative obscurity appear as constitutive not only for the subject life, but also for its moral self-commitment.
Development of the Pixel Detector for the Belle II experiment and top quark mass measurement in radiative events at the future electron-positron line…
2019
Durante los últimos cien años, los numerosos descubrimientos en los colisionadores de partículas y desarrollos teóricos han conducido a los físicos de partículas a construir el Modelo Estándar, el modelo teórico más exitoso hasta la fecha. Sin embargo, a pesar de su gran éxito, el Modelo Estándar no describe toda la fenomenología observada actualmente en los diferentes experimentos. Es por ello que se necesitan nuevos colisionadores que proporcionen observaciones de nueva física que nos ayuden a construir modelos que describan dicha fenomenología. Para enfrentarse al reto, la comunidad de física de partículas se une formando grandes colaboraciones, con el propósito de diseñar y construir lo…
