2007 Seat Belt Usage Survey, April 28, 2011

Surveys were taken of motor vehicle drivers’ and passengers’ seat belt usage. These surveys are before and after parts of the “Click it or Ticket” education and enforcement campaign. The whole project starts with a pre-campaign survey followed by the four-week public information, education and enforcement campaign. Finally, the postcampaign survey is taken to test the effectiveness of the education and enforcement campaign.

Iowa Seat Belt Use Survey 2012 Data Collection Methodology Report September 13, 2012

In an effort to achieve greater consistency and comparability in state‐wide seat belt use reporting, the National Highway Traffic Safety Administration (NHTSA) issued new requirements in 2011 for observing and reporting future seat belt use. The requirements included the involvement of a qualified statistician in the sampling and weighting portions of the process as well as a variety of operational details. The Iowa Governor’s Traffic Safety Bureau contracted with Iowa State University’s Survey & Behavioral Research Services (SBRS) in 2011 to develop the study design and data collection plan for the State of Iowa annual survey that would meet the new requirements of the NHTSA. A seat belt survey plan for Iowa was developed by SBRS with statistical expertise provided by Zhengyuan Zhu, Ph.D., Associate Professor of Statistics at Iowa State University. The Iowa plan was submitted to NHTSA in December of 2011 and official approval was received on March 19, 2012.

Landslide susceptibility in the Belt and Road Initiative

The Belt and Road Initiative (BRI) is a project launched by the Chinese Government whose main goal is to connect more than 65 countries in Asia, Europe, Africa and Oceania developing infrastructures and facilities. To support the prevention or mitigation of landslide hazards, which may affect the mainland infrastructures of BRI, a landslide susceptibility analysis in the countries involved has been carried out. Due to the large study area, the analysis has been carried out using a multi-scale approach which consists of mapping susceptibility firstly at continental scale, and then at national scale. The study area selected for the continental assessment is the south-Asia, where a pixel-based landslide susceptibility map has been carried out using the Weight of Evidence method and validated by Receiving Operating Characteristic (ROC) curves. Then, we selected the regions of west Tajikistan and north-east India to be investigated at national scale. Data scarcity is a common condition for many countries involved into the Initiative. Therefore in addition to the landslide susceptibility assessment of west Tajikistan, which has been conducted using a Generalized Additive Model and validated by ROC curves, we have examined, in the same study area, the effect of incomplete landslide dataset on the prediction capacity of statistical models. The entire PhD research activity has been conducted using only open data and open-source software. In this context, to support the analysis of the last years an open-source plugin for QGIS has been implemented. The SZ-tool allows the user to make susceptibility assessments from the data preprocessing, susceptibility mapping, to the final classification. All the output data of the analysis conducted are freely available and downloadable. This text describes the research activity of the last three years. Each chapter reports the text of the articles published in international scientific journal during the PhD.

Tectonics of the wedge-top Epiligurian basins and implications for the syn-to-post orogenic evolution of the Northern Apennines fold-and-thrust belt (Italy)

This thesis has the aim to give an overview about the tectonic history of the Epiligurian units, which crop out in the axial portion of the Northern Apennines fold-and-thrust belt, from a structural and thermal point of view, through a multiscalar and multitecnique approach. I focused on a key example of Epiligurian wedge-top basin, (Marzabotto Basin) proceeding from macro-to-microscale approach. The study started from a remote sensing analysis of the lineaments and morphostructures which affected the study area to obtain the regional faulting pattern and an overview about the main tectonic structures, used as basis for the structural investigation at the mesoscale. On the basis of this, it was possible to reconstruct the succession of tectonic events that affected the Marzabotto Basin, consisting in: i) two sets of thrusts indicating a NE-SW and NW-SE shortening of the sedimentary succession; ii) NE-SW-left lateral transtensional faults related to a strike-slip tectonic phase; iii) three main sets of extensional structures which cut and displace the previous thrusts. Normal faults are related to the post-orogenic evolution and have been dated with U-Th method, getting an age of Middle-Late Pleistocene. From a thermal point of view, apatite fission-tracks and (U-Th)/He analyses of detrital minerals and thermal modelling on the middle-upper Eocene siliciclastic deposits allowed me to better constrain the local exhumation history and correlate it with the large-scale tectonic evolution of the Northern Apennines. In particular, the Marzabotto Basin experienced a complex burial-exhumation history, consisting in two cooling cooling phases related to the growth of the Northern Apennines belt (Oligo-Miocene in age) and a later cooling which tracks the accretion in the orogenic wedge concomitant with rollback-driven extension (late Miocene-Pliocene in age). In conclusion it is possible to affirm that the study shed new light on poorly constrained elements of fold-and-thrust belt.

Transpressive dextral shear in the Italva-Itaperuna section, Northern State of Rio de Janeiro, Brazil

Structural analysis carried out on a segment of the Neoproterozoic Ribeira Belt, southeastern Brazil, show that it represents part of the transpressive dextral orogen related to the Central Mantiqueira Province. NNE-trending and steeply dipping regional mylonitic belts form anastomosed geometry, and describe a map-scale, S-C-like structure that is characterized by their deflection towards NE near the Além Paraíba Lineament. Lithological and structural control related to deformation partition were responsible for the formation of felsic mylonitic granulites with S-type granites lenses developed in ductile shear zones, alternated with less deformed intermediate to basic granulites associated with charnockites. The dextral shear sense indicators are consistent with transpressive deformation in the region and are common especially at the border of the main shear zones. The presence of S-type leucogranite may lead to variations of linear and planar relationships, which result in local extension zones. These elements are consistent with oblique continental collision considering the São Francisco Craton as a stable block.

Contribuição ao estudo do magmatismo Paleo e Mesoproterozóico do SW do Craton Amazônico através da aplicação de isótopos estáveis de O, H e S

Os isótopos estáveis de O, H e S foram utilizados para investigar a origem das rochas magmáticas nos Terrenos Jauru e Pontes e Lacerda do SW do Craton Amazônico, estado de Mato Grosso, Brasil. No Terreno Jauru as rochas granitóides do Greenstone belt Alto Jauru e da Suíte Cachoeirinha apresentam valores de δ18O entre +9,0‰ e +6,3‰ que indicam derivação a partir de magmas juvenis. Na Suíte Intrusiva Rio Branco valores de δ18O para rochas básicas estão entre +5,4‰ e +5,8‰ e para rochas félsicas entre +8,7‰ e +9,0‰; rochas intermediárias apresentam valores entre +7,3‰ e +8,3‰. Os valores mais baixos de δ18O, obtidos nas rochas básicas, são compatíveis com derivação mantélica, porém as rochas félsicas apresentam valores de δ18O compatíveis com origem crustais. Análises de isótopos estáveis de H (rocha total) forneceram valores de δD entre - 83‰ e -92‰, diferente das assinaturas de rochas metamórficas e de águas meteóricas. Resultados em sulfetos para isótopos estáveis de S em rochas básicas e intermediárias desta suíte apresentam valores de δ34S coerentes com uma fonte mantélica (entre + 0,7‰ e +3,8‰), enquanto os valores de δ34S (entre +5,2‰ e +6,1‰) obtidos nas rochas félsicas sugerem participação crustal na sua gênese. Na Suíte Santa Helena (Terreno Pontes e Lacerda) os resultados obtidos para δ18O se agrupam entre +4,4‰ e +8,9‰ indicando uma origem mantélica. O presente estudo confirma a importância da aplicação de isótopos estáveis para a compreensão de processos magmáticos e evolução crustal.
