Financial Crisis and Bank Ratings
2014
El principal objetivo de esta tesis doctoral es el análisis del comportamiento de las agencias de calificación cuando evalúan a las entidades bancarias así como el efecto que tienen sus ratings sobre los mercados financieros antes y durante la crisis financiera que se inicia en el año 2007. Si bien es cierto que en la literatura existen numerosos trabajos que se centran en el estudio de los ratings soberanos en cuanto a modelización e impacto que tienen los ratings en los mercados financieros, prácticamente ninguno de ellos se centra en el caso de los ratings bancarios y menos en el contexto de crisis financiera. El segundo capítulo de la tesis doctoral tienen como principal objetivo el aná…
Assessment of bank financial health in Latvia
2019
Financially strong, trustworthy and reliable banks form the basis of every economy and are a vital precondition for the stable economic development of every country. The financial health of banks is important for different stakeholders, including bank clients, correspondent banks, state and others. Therefore, lack of appropriate measures for bank financial health can cause a number of risks for the bank stakeholders. Traditionally the assessment of bank financial health and reliability is done by the international rating agencies as Standard & Poor’s, Moody’s and Fitch. These ratings are widely recognized worldwide; however, due to different reasons ratings assigned by the international rat…
Folklorystyczny aspekt współczesnych narracji potocznych
2020
Zainteresowanie folklorystyki współczesnymi narracjami potocznymi wynika z przedefiniowania przedmiotu badań folklorystycznych. Uznanie folkloru za część kultury, która podlega takim samym przemianom jak cała kultura i jest zjawiskiem społecznie oraz historycznie zróżnicowanym, wymaga doprecyzowania podstawowych pojęć: oralności, kontekstu kulturowego, sytuacji folklorotwórczej, procesu odbioru przekazywanych treści. Oralności nie można bowiem sprowadzać tylko do ustnego (bezpośredniego) sposobu przekazywania treści, ponieważ jest ona także sposobem egzystencji człowieka, poznawania i rozumienia świata. Należy zatem dokładnie przeanalizować zmiany zachodzące w przestrzeni społeczno-kulturow…
ANALISI GIS E MODELLI STATISTICI PER LA VALUTAZIONE DELLA SUSCETTIBILITÀ DA FRANA A SCALA DI BACINO: IL CASO STUDIO DEL BACINO DEL TORRENTE MARVELLO
Lo studio condotto nel presente lavoro di tesi ha affrontato il tema della valutazione, a scala di bacino idrografico, della suscettibilità ai fenomeni di tipo colamento, attraverso l’applicazione di modelli statistici e tecniche di analisi spaziale GIS. La fase iniziale della preparazione di un modello di suscettibilità da frana prevede la realizzazione di un inventario degli eventi verificatesi nell’area di studio. Questo passo è di fondamentale importanza, considerando che proprio attraverso l’archivio frane è possibile analizzare ed individuare le condizioni che in passato hanno favorito l’innesco dei movimenti di versante. L’identificazione di queste condizioni, infatti, consente di pr…
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
2023
Background: Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods: This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, r…
Could tsunami risk be underestimated using core‐based reconstructions? Lessons from ground penetrating radar
2017
Where should we take cores for palaeotsunami research? It is generally considered that local depressions with low energy environments such as wetlands are one of the best places. However, it is also recognized that the presence or absence of palaeotsunami deposits (and their relative thickness) is highly dependent upon subsoil microtopography. In the beach ridge system of Ishinomaki Plain, Japan, several palaeotsunami deposits linked to past Japan Trench earthquakes have been reported. However, the number of palaeotsunami deposits reported at individual sites varies considerably. This study used ground penetrating radar (GPR) combined with geological evidence to better understand the relati…
Detailed subglacial topography and drumlins at the marginal zone of Múlajökull outlet glacier, central Iceland: Evidence from low frequency GPR data
2016
Abstract New ground penetrating radar (GPR) observations on the Mulajokull surge-type outlet glacier, central Iceland, are presented. Overall 10.5 km of GPR profile lines were recorded parallel to the glacier margin in August, 2015. Detailed GPR investigations combined with high-accuracy GPS measurements allowed to build a high-resolution model of the subglacial topography. We provide new evidence of streamlined ridges beneath Mulajokull’s marginal zone interpreted as drumlins and show the location of the upper edge of the drumlin field. This discovery improves understanding of the location, morphology and development of drumlins as other geophysical observations of subglacial bedforms bene…
Insar time-series analysis for management and mitigation of geological risk in urban area
2010
This work shows the capabilities of InSAR time series analyses to support civil protection activities in the framework of geological risk management and mitigation. We discuss the outcomes from an integrated analysis of conventional in situ investigations and observations with advanced InSAR analyses carried out for the test sites of Agrigento and Naro (Italy), affected by ground instability respectively due to landsliding and tectonic forces. The study of past ground deformations provided valuable insights into the spatial and temporal patterns and behaviors of these phenomena, helping local civil protection authorities to focus resources on the areas of maximum need and to identify the mo…
Forward logistic regression for earth-flow landslide susceptibility assessment in the Platani river basin (southern Sicily, Italy)
2013
Forward logistic regression has allowed us to derive an earth-flow susceptibility model for the Tumarrano river basin, which was defined by modeling the statistical relationships between an archive of 760 events and a set of 20 predictors. For each landslide in the inventory, a landslide identification point (LIP) was automatically produced as corresponding to the highest point along the boundary of the landslide polygons, and unstable conditions were assigned to cells at a distance up to 8 m. An equal number of stable cells (out of landslides) was then randomly extracted and appended to the LIPs to prepare the dataset for logistic regression. A model building strategy was applied to enlarg…
