No full textA questão do financiamento de longo prazo no Brasil: uma revisão histórica
No full textTCC (graduação) - Universidade Federal de Santa Catarina. Centro Sócio-Econômico. Economia.No processo de crescimento econômico, principalmente em economias emergentes que necessitam desenvolver o setor de infra-estrutura, o financiamento de longo prazo constitui um mecanismo fundamental para a viabilização de investimentos. A falta de mecanismos internos eficazes de financiamento privado de longo prazo dentro do Sistema Financeiro, ao longo da história, impôs barreiras em relação ao crescimento econômico do Brasil. O baixo crescimento econômico do nosso país durante muitas décadas resulta, em grande parte, de um sistema financeiro subdesenvolvido com claras deficiências no que se refere ao mercado de capitais e ao sistema bancário privado como elementos de suporte para as empresas realizarem seus investimentos. Este trabalho busca analisar o modelo de financiamento adotado no Brasil no século XX, além do papel atual do sistema financeiro doméstico na oferta de crédito privado
Ritorno al Pireo. Alcune riflessioni sull'organizzazione urbana e sulla cronologia dell'impianto
No full textIn this paper the author discusses the town plan of Piraeus to shed further light on some aspects he already examined in a previous article (Longo 2008). Starting from the most recent archaeological data that were overlooked in some recent studies, and the literary and epigraphic documentation, the author attempts to capture the essential elements informing the development plan of Hippodamus of Miletus, viz., functionality and the likely pre-existence of the main street axes; the characteristics of the urban grid; a clear demarcation of public and private spaces; and the issue of the location of the two agorai mentioned in literary sources.
In questo contributo l’Autore riprende la discussione sull’urbanistica del Pireo chiarendo e precisando aspetti in parte già affrontati in un precedente articolo (Longo 2008). Partendo dai dati archeologici più recenti, poco valorizzati in alcune sintesi di questi ultimi anni, e dalla documentazione letteraria ed epigrafica, l’Autore cerca di cogliere gli elementi essenziali che sono alla base del progetto urbanistico di Ippodamo di Mileto: funzionalità e probabile preesistenza degli assi viari principali; caratteristiche della griglia urbana; netta delimitazione degli spazi pubblici e privati; cronologia dell’impianto; problema della localizzazione delle due agorai menzionate nelle fonti letterarie
Gamma-ray bursts within fireshell model
No full textThis thesis is mainly focused on careful data analysis of different parts of high-energy (sub-keV--GeV) spectra of gamma-ray bursts. All the interpretation works are based on the theoretical ground of the fireshell paradigm which is being continuously developed for over 20 years.
The chapters in the main body of the thesis focus on current research and results obtained and published. A distinct emphasis on spectral bands is expressed through structural division of the thesis: soft gamma-ray emission, x-ray afterglow emission and high-energy gamma-ray emission.
In Chapter 2 we discuss theoretical and observational evidences which have been recently gained for a two-fold classification of short bursts within the fireshell working paradigm. We present three additional S-GRBs, 081024B, 090510 and 140402A, following the already identified S-GRBs, i.e., 090227B and 140619B.
In Chapter 3 we analyze the early X-ray flares in the GRB "flare-plateau-afterglow" (FPA) phase observed by Swift-XRT. We claim that the FPA occurs only in one of the subclasses---binary-driven hypernovae (BdHNe). This subclass consists of long GRBs with a carbon-oxygen core (CO_core) massive star and a neutron star (NS) binary companion as progenitors.
In Chapter 4 we examine a scenario when in binary system of neutron star (NS) and massive CO_core star, the latter undergoes a supernova (SN) explosion. A black hole (BH) subsequently originates from the gravitational collapse of the NS caused by hypercritical accretion of the SN ejecta. We infer a new asymmetric morphology for the BdHNe system where the GeV emission occurs within a cone of half-opening angle approximately 60 degrees normal to the orbital plane of the binary progenitor. We confirm that GeV luminosity light curves follow the universal power-law with index of -1.19 +/- 0.04, and from this we further estimate the spin-down rate of the BH

No full textThe Author and Authorship in the Internet Society. New Perspectives for Scientific Communication
No full textThe Internet is the most recent and relevant innovation in the field of
media communication, as well as the medium that reproduces most of the characteristics
of global society. In trying to describe contemporary society, we cannot
neglect the social implication of the web. Our assumption is that the evolution of
the Internet has led to problematic effects on the relevance of concepts such as
individuality, author, authorship and copyright, as commonly used up till now.
The first part of the article focuses on individuality as a means to describe individual
actors and social structures in the first modernity, paying particular attention
to the idea of the author as an individual in the field of intellectual products.
New communication forms online make the connection between the individuality
of the author and the text weaker and less recognizable. The second part develops
the theme of scientific knowledge in contemporary society, with regard to scholarly
authorship. The Internet has produced deep transformations in scholarly
publications. Technical and structural characteristics of the Internet suggest possibilities
for a reorganization of the scientific system towards the replacement of
authorship and reputation with innovative mechanisms of information processing
and selection

No full textLambda-adic modular symbols over totally real fields
No full textWe consider a Hida family of nearly ordinary cusp forms on a quaternion algebra defined over a totally real number field. The aim of this work is to construct a cohomology class with coefficients in a p-adic sheaf over an Iwasawa algebra that can be specialized to cohomology classes attached to classical cusp forms in the given Hida family. Our result extends the work of Greenberg and Stevens on modular symbols attached to ordinary Hida families when the ground field is the field of rational numbers
