Applying the Disruption Index procedure to evaluate the urban seismic risk in the Mt. Etna area (Italy)
The Disruption Index is used here for the assessment of urban disruption in the Mt. Etna area
after a natural disaster. The first element of the procedure is the definition of the seismic input,
which is based on information about the historical seismicity and seismogenic faults. The second
element is the computation of the seismic impact on the building stock and infrastructure in the
region considered. Information on urban-scale vulnerability was collected and a geographic
information system was used to organize the data relating to buildings and network systems (e.
g., typologies, schools, strategic structures, lifelines). The central idea underlying the definition
of the Disruption Index is the identification and evaluation of the impacts on a target community,
considering the physical elements that contribute most to the severe disruption. The results of
this study are therefore very useful for earthquake preparedness planning and for the
development of strategies to minimize the risks from earthquakes. This study is a product of the
European “Urban Disaster Prevention Strategies using Macroseismic Fields and Fault Sources”
project (UPStrat-MAFA European project 2013).PublishedTorino, Italy3T. Pericolosità sismica e contributo alla definizione del rischioope
On assessing importance of components in dysfunction urban systems given an earthquake: the case of Mt. Etna region
Mt Etna region (Sicily, Italy) is one of the test areas studied in the European Project “Urban
disaster Prevention Strategies using MAcroseismic fields and FAult sources” ( UPStrat-MAFA) to
which the methodology of Disruption Index (hereafter DI), recently developed to evaluate the
dysfunction of urban systems caused by earthquakes (Ferreira et al., 2014), has been applied on a trial
basis
Non-Structural Risk Evaluation: Experiences From Pilot Areas Of The Knowrisk Project
This paper presents a multidisciplinary approach to quantify seismic hazard and ground motion intensity parameters for non-structural seismic risk evaluation. In the framework of the European KnowRISK Project, three pilot areas were selected for testing different methodological approaches aimed at evaluating elements and measures to reduce seismic risk coming along with the failure of non-structural elements. At Mt. Etna, Italy, instrumental and historical macroseismic data are used to generate ground motion time series for different scenario events. Risk maps for non-structural damage are generated by using building vulnerability from census data and a damage model based on fragility curves; interstory drift spectra have been also calculated for a representative test site. In South Iceland, scenarios are defined basing on the June 2000 seismic sequence, which provided strong-motion data at several locations. The recorded data and other parameters of the source are used to perform finite-fault simulations of ground motion at different locations in the area and then to calculate interstory drift spectra. In Portugal a scenario referring to the Lower Tagus Valley was selected and finite-fault simulations for the nearby city of Lisbon were performed.PublishedThessaloniki, Greece5T.

Palynological and chemical volatile components of tipically autumnal honeys of the western Mediterranean
[EN] Twenty-five samples of autumnal honeys from the western Mediterranean (Mallorca and Eivissa, Balearic Islands) were examined for pollen content (qualitative and quantitative melissopalynological analysis), moisture, electrical conductivity, colour, sensorial qualities and volatile components. Quantitative analysis showed that the honey contained Maurizio's Class II: 64%, Class III: 28%, Class IV: 4% and Class V: 4%. Fifty-four pollen types, with an average number of 16.68 per sample, were identified, belonging to 29 botanical families. Only two taxa (Ceratonia siliqua and Erica multiflora) were found in all samples. Seventeen samples were unifloral (68%) - ten (40%) of C. siliqua, six (24%) of E. multiflora and one (4%) of Hedera helix. All honeys have a low honeydew index (<?0.09%), while the values for electrical conductivity and water content were high. The major honey volatile components are: cis- and trans-linalool oxides (64.2%) and hotrienol (10.4%) for the carob (C. siliqua) and trans-linalool oxide (13.4%), p-menthane-1,8-diol (11.1%), safranal (9.7%), limonene (5,4%), -pinene (3.7%) and oxoisophorone (3.4%) for the winter heather (E. multiflora).The authors would like to extend their gratitude to the Mallorca Rural 'Leader plus' programme and the beekeepers of Mallorca and Eivissa for their support and friendly collaboration. The authors also thank an anonymous reviewer for useful comments and suggestions on an earlier version of the manuscript.Boi, M.; Llorens Molina, JA.; Cortés, L.; Lladó, G.; Llorens, L. (2013).

BRAZIL’S NUCLEAR SUBMARINE PROGRAM: NAVIGATING THE UNCHARTED WATERS OF THE NON-PROLIFERATION TREATY
Brazil’s rise as a political and economic power has received significant media
attention in recent years. International observers predict that Brazil will emerge as a
regional superpower and as a significant player on the world stage in the 21 century.
Equally important but less discussed is Brazil’s role as a nuclear-capable, but
nuclear-weapon-free country. Non-proliferation advocates are suspicious of Brazil’s
military ambitions and push for more severe restrictions on its nuclear program. Brazil’s
leaders, on the other hand, argue that Brazil is an exemplar in non-proliferation efforts
and see remilitarization and nuclear development as stepping-stones to well-deserved
influence on the world stage. This contention is best illustrated in the country’s efforts to
develop nuclear-powered submarines (SSNs).
This thesis has two parts. The first seeks to establish the first comprehensive
historical account of Brazil’s nuclear program in the English language—paying particular
attention to the Navy’s pursuit of SSNs. Drawing from official
government
documents,
investigative
reports,
memoirs,
history
books,
and
personal
interviews,
the first four
chapters describe the chronology of the program in four distinct phases: its modest
beginnings, evolution under the military regime, its descent into secrecy, and
developments since democratization. While
I
strive
to
provide
as
many
historical
details
as
possible,
many
matters
discussed
in
this
thesis
remain
classified
by
the
Brazilian
government.
When
necessary,
I
highlight
the
resulting
ambiguities
and
controversies.
The second part of the thesis discusses the technical and legal complications
facing Brazil’s nuclear submarine program and examines how Brazilian SSNs may affect
international non-proliferation institutions like the Non-Proliferation Treaty (NPT).
Brazil stands as the first non-nuclear weapons state to test what many consider a
dangerous “loophole” in NPT safeguards arrangements. I argue that Brazil is positioned
to set responsible precedents for the implementation of safeguards agreements for naval
fuel cycles. This issue has grown increasingly relevant, as countries like Iran have
expressed aspirations to develop indigenous fuel cycles and nuclear submarine forces.
After discussing various considerations for US foreign policy, I conclude with
recommendations for how to adapt existing non-proliferation institutions to close the
NPT “loophole.”
This thesis draws heavily from my research in Brazil, where I was fortunate to
have had the opportunity to interview some of the key figures in the history of Brazil’s
nuclear program. Where possible, the thesis examines Brazilian intentions, ideologies,
and perspectives in the context of historical events— many of which may be unfamiliar
to a US readership. In so doing, it hopes to clarify some misunderstandings and
disagreements between Washington and Brasília
Modélisation de la construction identitaire professionnelle de jeunes médecins généralistes diplômés de l'Université fédérale du Pernambouco, au Brésil
Cette thèse porte sur la construction identitaire professionnelle de jeunes médecins généralistes diplômés de l'Université fédérale de Pernambouco, au Brésil. En considérant que le milieu de formation joue un rôle important en tant qu'agent reconnu de socialisation pour les médecins, nous avons choisi des jeunes issus d'une même université pour étudier leur processus de construction d'identité professionnelle. Pour cela, nous avons suivi les propos de Claude Dubar (1996) qui tiennent compte de deux transactions principales dans ce processus : la transaction biographique et la transaction relationnelle. Nous avons considéré les milieux de socialisation primaire (la famille) et de socialisation secondaire (l'université et le milieu du début de la pratique). Les jeunes devaient être déjà en début d'exercice pour pouvoir se rapporter aux valeurs de la pratique aussi bien qu'aux valeurs du milieu de formation. La place donnée aux valeurs a été notre fil conducteur. Les questions de notre recherche portaient sur le développement des valeurs pendant le parcours de leur construction identitaire professionnelle. Nous y avons répondu et nous sommes allée [i.e. allés] plus loin en modélisant leur processus de construction identitaire à partir de l'émergence d'un tronc identitaire commun. La mise en place d'une analyse en fonction des catégories conceptualisantes selon Paillé et Mucchielli (2003) nous a permis d'y arriver. Pour faire émerger un tronc identitaire commun, nous avons catégorisé les similarités dans les discours des jeunes. Nous avions un groupe sorti de la même université, de la même promotion, sauf deux jeunes, du même groupe d'âge. Tous ont choisi des carrières généralistes. Alors, nous avons cherché quel était le tronc commun à leur construction identitaire. Des nuances ont été faites par rapport aux différences socio-démographiques et relationnelles des jeunes généralistes.Cette thèse se veut originale, car nous ne connaissons pas d'étude portant sur la construction identitaire des médecins généralistes qui tienne compte au départ des propos de Dubar au Brésil. L'originalité vient aussi de la méthodologie qui, en suivant Paillé et Mucchielli (2003) a mis en place une modélisation de cette construction particulière. Pour cette modélisation nous avons utilisé les trois approches proposées par ces auteurs pour la mise en relation des catégories conceptualisantes : l'approche empirique, l'approche spéculative et l'approche théorique qui reprend le cadre conceptuel de la thèse
