Les enquêtes militaires et l-organisation des intellectuels de gauche au Brésil dans les années 1960

This article has as its object of analysis the Inquiries Police-Military, adocumentation produced during the military dictatorship in Brazil (1964-1985)and today it’s important sources for historians, sociologists, political scientists to understand the internal dynamics of repression, as well as specifying certainnetworks communist militancy and the engagement of progressive sectorsagainst the military government. Documents, court proceedings that currently in Brazil endorse the work of the Truth Commission, which seeks to ascertain the fate of disappeared politicians and determine the actions of the organs of repression during the military dictatorship in Brazil.

O paradigmático caso do processo às juntas militares argentinas

This article analyzes the case of the proceedings against Argentina’s Military Juntas that led to jail those responsible for heinous crimes committed during the military dictatorship. The said proceeding has a high symbolic value in the struggle for human rights in Latin America and is relevant and timely in Brazil where the right to the truth regarding the missing people during the military dictatorship is in debate, as well as the invalidation of the Amnesty Act regarding the common crimes of torture, rape and / or kidnapping, among others. In the case of Argentina, following Roxin’s doctrine of mediate authorship, the Court held that the crimes were committed by the military through the use of an organized power apparatus and emphatically dismissed allegations that such crimes were justified in the so-called “dirty war”. Thus, the case against the Military Juntas has become a paradigmatic one, not only in Argentina, where many military leaders had to respond to criminal actions, but for all countries in the region that faced similar situations in recent history.

Constraint-based analysis of gene interactions using restricted boolean networks and time-series data

Abstract Background A popular model for gene regulatory networks is the Boolean network model. In this paper, we propose an algorithm to perform an analysis of gene regulatory interactions using the Boolean network model and time-series data. Actually, the Boolean network is restricted in the sense that only a subset of all possible Boolean functions are considered. We explore some mathematical properties of the restricted Boolean networks in order to avoid the full search approach. The problem is modeled as a Constraint Satisfaction Problem (CSP) and CSP techniques are used to solve it. Results We applied the proposed algorithm in two data sets. First, we used an artificial dataset obtained from a model for the budding yeast cell cycle. The second data set is derived from experiments performed using HeLa cells. The results show that some interactions can be fully or, at least, partially determined under the Boolean model considered. Conclusions The algorithm proposed can be used as a first step for detection of gene/protein interactions. It is able to infer gene relationships from time-series data of gene expression, and this inference process can be aided by a priori knowledge available.

Different approaches for dealing with rare variants in family-based genetic studies: application of a Genetic Analysis Workshop 17 problem

Rare variants are becoming the new candidates in the search for genetic variants that predispose individuals to a phenotype of interest. Their low prevalence in a population requires the development of dedicated detection and analytical methods. A family-based approach could greatly enhance their detection and interpretation because rare variants are nearly family specific. In this report, we test several distinct approaches for analyzing the information provided by rare and common variants and how they can be effectively used to pinpoint putative candidate genes for follow-up studies. The analyses were performed on the mini-exome data set provided by Genetic Analysis Workshop 17. Eight approaches were tested, four using the trait’s heritability estimates and four using QTDT models. These methods had their sensitivity, specificity, and positive and negative predictive values compared in light of the simulation parameters. Our results highlight important limitations of current methods to deal with rare and common variants, all methods presented a reduced specificity and, consequently, prone to false positive associations. Methods analyzing common variants information showed an enhanced sensibility when compared to rare variants methods. Furthermore, our limited knowledge of the use of biological databases for gene annotations, possibly for use as covariates in regression models, imposes a barrier to further research.

Pacta sunt servanda versus the social role of contracts: the case of Brazilian agriculture contracts

This study explores the instability created by contradictory court decisions related with contract breaches. Forward marketing contracts represent an important source of resources to finance Brazilian agriculture, however a large number of contract breaches were observed during a period of marked increase in soy prices. The study analyzed 161 judicial appeal decisions and a survey was carried with 70 farmers. The results show the difference of judges' interpretation and the existence of second order effects. The effects of court decisions were more requirements of guarantees and the reduction in the number of contracts. Those soybean farmers who did not breach their contracts have also been negatively affected by the strategic reactions of trading and processing companies. The concept of "social function of the contract" introduced in Brazilian civil code led to a higher degree of instability in contracts, raising transaction costs and motivating private economic sanctions.

L'utilizzabilità degli atti nella fase investigativa. La prova per le indagini preliminari

The doctorate’s theme of research - Abstract My doctorate’s theme of research is about the Investigation in the Italian criminal proceedings. The Italian Code of criminal procedure of 1988 is the fruit of a new ideology that marks a departure from Italy’s prior inquisitorial tradition. According to criminal procedure Code of 1988, an accusatorial system separates the investigation and trial stages and the judge’s decision is based only on evidence collected in oral form in his presence in a public trial containing adversarial dynamics. The Italian Code of 1988 created a separation between criminal investigations and trial. Investigations are conducted by Public Prosecutor: he conducts the investigation phase in order to deem whether to file a formal charge against the defendant or to dismiss the case and the investigative evidence collected should serve only for this purpose. According to so called “inutilizzabilità fisiologica”’s rule, the evidence collected during investigations by prosecutor is not usable during trial by the judge: the results of the investigative efforts displayed by the parties should be kept outside of court. If the proceedings go on to trial, the case shall be deemed with only evidence collected in front of the judge. To create the separation of the trial phase from the investigation stage, there is the double-dossier system. During the investigations, evidence are collected in an investigation dossier. The trial judge will never see the investigation dossier and the trial judge’s decision is based on a new dossier, the trial dossier, with the evidence collected during the trial. The issue of my research is about the investigation, the so called “inutilizzabilità fisiologica”’s rule and also the exclusionary rules that concern the investigative phase and the decisions pronounced during the investigations (for example, the decisions concerning pre-trial confinement). 2 In fact, the exclusionary rule system (so called “inutilizzabilità patologica”) provides that evidence cannot be used in Italian criminal proceedings if it was the result of illegal inquiry.

Insolvenza transfrontaliera e giurisdizione: l'esperienza del regolamento (CE) n. 1346 del 2000

L’elaborato è strutturato in quattro parti: la prima è dedicata all’inquadramento del background normativo. L’autrice affronta, con un approccio ricostruttivo, i precedenti alla redazione del regolamento e le difficoltà incontrate a causa delle resistenze degli Stati membri. Si sofferma altresì sulle norme UNCITRAL, anch’esse oggetto nel recente periodo, di numerose implementazioni. La seconda parte fotografa il ruolo della Corte di Giustizia nell’interpretazione del regolamento n. 1346/2000 ed individua i concetti fondamentali del regolamento: l’universalità attenuata, il campo di applicazione soggettivo del regolamento, la legge applicabile, il principio dell’automatico riconoscimento delle decisioni e la correlata tematica dell’ordine pubblico, nonché la figura del curatore. Si approfondisce l’attività degli Stati membri nel dotarsi di norme di coordinamento ( esemplare il caso della Spagna e della Germania) sottolineando il silenzio del legislatore italiano che, nonostante le numerose riforme in materia, a tutt’oggi non ha ideato un sistema in grado di coordinare la normativa nazionale con la struttura del regolamento europeo. Nella terza parte l'autrice approfondisce la giurisdizione nel regolamento n. 1346/2000. Si individuano le parole chiave: Comi e dipendenza, i cui significati sono sfumati seguendo le posizioni della Corte di Giustizia, (Leading Case Eurofood sino a Interedil) e si mette in discussione, nel panorama attuale, la tenuta di tali criteri giurisdizionali. Sempre intorno al concetto di Comi, si analizzano: la giurisdizione verso gruppi di imprese disciplina assente nel regolamento, i rapporti tra procedura principale e secondaria , la giurisdizione in materia di azioni connesse e/o correlate (Gourdain vs Nadler/Seagon vs Deko Marty). Il capitolo conclusivo offre una panoramica delle proposte finalizzate ad un’implementazione della struttura del regolamento sull’insolvenza. Numerose, infatti, sono le proposte a livello dottrinale e da parte degli organi comunitari in vista della scadenza del Report della Commissione Europea sulla applicazione del regolamento 1346 del 2000 (art. 46).

Il potere normativo delle Corti sul processo

La tesi intende offrire una riflessione in merito al potere degli organi giurisdizionali di disporre normativamente su determinati aspetti del processo che si svolge dinanzi ad essi, sostituendosi così al legislatore. Il piano di indagine della tesi si sviluppa prevalentemente nella descrizione della realtà europea davanti alle autorità giurisdizionali di Lussemburgo, attraverso continui riferimenti a pronunce giurisprudenziali. La candidata si sofferma, preliminarmente, definendo, in termini generali, l’origine e l’applicazione dei c.d. atti di soft law in ambito europeo e soffermandosi sul ruolo che ricopre la giurisprudenza nell’ordinamento europeo. Sempre nel capitolo di apertura, un accenno è dedicato al panorama italiano che, alla luce delle recenti e continue riforme processuali ed, in particolare, della lettura costituzionalmente orientata del processo civile in forza della sua ragionevole durata, sta conoscendo, sempre più largamente, il fenomeno dei c.d. protocolli. La tesi si sviluppa, poi, in altri tre capitoli, nei quali sono analizzati tre esempi di manifestazione del potere normativo degli organi giurisdizionali europei sul processo. La candidata passa, così, all’esame delle “Istruzioni pratiche alle parti”, sviscerando le disposizioni ivi contenute alla luce di casi giurisprudenziali, al fine di poter definire la reale efficacia di tali atti e la loro vincolatività nei confronti dei rappresentanti delle parti. A tale capitolo segue quello sull’applicazione del rinvio pregiudiziale tra soft law (c.d. Raccomandazioni) e giurisprudenza. Infine, la candidata svolge le ultime riflessioni sul potere “eccezionale” della Corte di giustizia di limitare nel tempo gli effetti delle proprie sentenze interpretative. Potere che, in questo caso, si manifesta non mediante l’emanazione di atti di soft law, ma attraverso le proprie pronunce giurisprudenziali.

Caratteristiche innovative nell'acquisizione di dati di informatica forense in ambienti virtuali

Come risposta positiva alle richieste provenienti dal mondo dei giuristi, spesso troppo distante da quello scientifico, si vuole sviluppare un sistema solido dal punto di vista tecnico e chiaro dal punto di vista giurico finalizzato ad migliore ricerca della verità. L’obiettivo ci si prefigge è quello di creare uno strumento versatile e di facile utilizzo da mettere a disposizione dell’A.G. ed eventualmente della P.G. operante finalizzato a consentire il proseguo dell’attività d’indagine in tempi molto rapidi e con un notevole contenimento dei costi di giustizia rispetto ad una normale CTU. La progetto verterà su analisi informatiche forensi di supporti digitali inerenti vari tipi di procedimento per cui si dovrebbe richiedere una CTU o una perizia. La sperimentazione scientifica prevede un sistema di partecipazione diretta della P.G. e della A.G. all’analisi informatica rendendo disponibile, sottoforma di macchina virtuale, il contenuto dei supporti sequestrati in modo che possa essere visionato alla pari del supporto originale. In questo modo il CT diventa una mera guida per la PG e l’AG nell’ambito dell’indagine informatica forense che accompagna il giudice e le parti alla migliore comprensione delle informazioni richieste dal quesito. Le fasi chiave della sperimentazione sono: • la ripetibilità delle operazioni svolte • dettare delle chiare linee guida per la catena di custodia dalla presa in carico dei supporti • i metodi di conservazione e trasmissione dei dati tali da poter garantire integrità e riservatezza degli stessi • tempi e costi ridotti rispetto alle normali CTU/perizie • visualizzazione diretta dei contenuti dei supporti analizzati delle Parti e del Giudice circoscritte alle informazioni utili ai fini di giustizia

Impaired immune evasion in HIV through intracellular delays and multiple infection of cells

With its high mutation rate, HIV is capable of escape from recognition, suppression and/or killing by CD8(+) cytotoxic T lymphocytes (CTLs). The rate at which escape variants replace each other can give insights into the selective pressure imposed by single CTL clones. We investigate the effects of specific characteristics of the HIV life cycle on the dynamics of immune escape. First, it has been found that cells in HIV-infected patients can carry multiple copies of proviruses. To investigate how this process affects the emergence of immune escape, we develop a mathematical model of HIV dynamics with multiple infections of cells. Increasing the frequency of multiple-infected cells delays the appearance of immune escape variants, slows down the rate at which they replace the wild-type variant and can even prevent escape variants from taking over the quasi-species. Second, we study the effect of the intracellular eclipse phase on the rate of escape and show that escape rates are expected to be slower than previously anticipated. In summary, slow escape rates do not necessarily imply inefficient CTL-mediated killing of HIV-infected cells, but are at least partly a result of the specific characteristics of the viral life cycle.

Radiolabeled somatostatin receptor antagonists are preferable to agonists for in vivo peptide receptor targeting of tumors

Targeting neuroendocrine tumors expressing somatostatin receptor subtypes (sst) with radiolabeled somatostatin agonists is an established diagnostic and therapeutic approach in oncology. While agonists readily internalize into tumor cells, permitting accumulation of radioactivity, radiolabeled antagonists do not, and they have not been considered for tumor targeting. The macrocyclic chelator 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) was coupled to two potent somatostatin receptor-selective peptide antagonists [NH(2)-CO-c(DCys-Phe-Tyr-DAgl(8)(Me,2-naphthoyl)-Lys-Thr-Phe-Cys)-OH (sst(3)-ODN-8) and a sst(2)-selective antagonist (sst(2)-ANT)], for labeling with (111/nat)In. (111/nat)In-DOTA-sst(3)-ODN-8 and (111/nat)In-DOTA-[4-NO(2)-Phe-c(DCys-Tyr-DTrp-Lys-Thr-Cys)-DTyr-NH(2)] ((111/nat)In-DOTA-sst(2)-ANT) showed high sst(3)- and sst(2)-binding affinity, respectively. They did not trigger sst(3) or sst(2) internalization but prevented agonist-stimulated internalization. (111)In-DOTA-sst(3)-ODN-8 and (111)In-DOTA-sst(2)-ANT were injected intravenously into mice bearing sst(3)- and sst(2)-expressing tumors, and their biodistribution was monitored. In the sst(3)-expressing tumors, strong accumulation of (111)In-DOTA-sst(3)-ODN-8 was observed, peaking at 1 h with 60% injected radioactivity per gram of tissue and remaining at a high level for >72 h. Excess of sst(3)-ODN-8 blocked uptake. As a control, the potent agonist (111)In-DOTA-[1-Nal(3)]-octreotide, with strong sst(3)-binding and internalization properties showed a much lower and shorter-lasting uptake in sst(3)-expressing tumors. Similarly, (111)In-DOTA-sst(2)-ANT was injected into mice bearing sst(2)-expressing tumors. Tumor uptake was considerably higher than with the highly potent sst(2)-selective agonist (111)In-diethylenetriaminepentaacetic acid-[Tyr(3),Thr(8)]-octreotide ((111)In-DTPA-TATE). Scatchard plots showed that antagonists labeled many more sites than agonists. Somatostatin antagonist radiotracers therefore are preferable over agonists for the in vivo targeting of sst(3)- or sst(2)-expressing tumors. Antagonist radioligands for other peptide receptors need to be evaluated in nuclear oncology as a result of this paradigm shift.
