Analysis of expression quantitative trait loci in D. melanogaster

Expression Quantitative Trait Loci (eQTL) analysis allows for the identification of genetic variation associated with variation in gene expression. It is often unclear however, which of the associated variants are causal, and by what mechanism. Integrating functional genomic data with eQTL data can provide insight into the impact of natural variation in the population, and the nature of the transcriptional machinery itself. In this thesis, I integrate functional genomic data with eQTL data derived from both 5’ CAGE and 3’ TagXseq expression assays, in developing embryos. I first use both datasets to analyse the transcription landscape in embryonic D., melanogaster, and then carry out an analysis of sequence motifs associated with transcription factor binding sites, promoters, and 3’ polyadenylation sites. Finally, I integrate functional genomic data, including these novel sequence motifs, to shed light on the mechanisms of gene expression variation in D.,melanogaster. I am able to demonstrate that some variants effecting gene regulation in Drosophila are found within haplotypes which buffer their effects.

Legal Translation from English to Spanish in the Classroom: Problems when Translating Standard Formulas of Expression

The purpose of this paper is to identify problems when translating standard formulas of expression in English to Spanish legal translation. To achieve the goal, a total of 250 Spanish translations were analyzed of 10 sentences from legal texts in English. The degree of difficulty posed by the translation of these formulas is confirmed by the results obtained, which is related not so much to the intrinsic meaning of the words that compose them, but to their contextual meaning. An eclectic approach that combines discourse analysis with contrastive linguistics is proposed, and some specific didactic guidelines are indicated to facilitate the translation teaching of these standard formulas of expression. Lexical interpretation and contextual recreation allow the apprentice translator to make progress with the translation of these phrases and to improve his/her attitude when facing them to achieve a successful semantic and contextual interpretation, that is to say, getting the closest natural equivalent while respecting the genius of the language.

Identification of superior reference genes for data normalisation of expression studies via quantitative PCR in hybrid roses (Rosa hybrida)

Background: Gene expression studies are a prerequisite for understanding the biological function of genes. Because of its high sensitivity and easy use, quantitative PCR (qPCR) has become the gold standard for gene expression quantification. To normalise qPCR measurements between samples, the most prominent technique is the use of stably expressed endogenous control genes, the so called reference genes. However, recent studies show there is no universal reference gene for all biological questions. Roses are important ornamental plants for which there has been no evaluation of useful reference genes for gene expression studies. Results: We used three different algorithms (BestKeeper, geNorm and NormFinder) to validate the expression stability of nine candidate reference genes in different rose tissues from three different genotypes of Rosa hybrida and in leaves treated with various stress factors. The candidate genes comprised the classical "housekeeping genes" (Actin, EF-1α, GAPDH, Tubulin and Ubiquitin), and genes showing stable expression in studies in Arabidopsis (PP2A, SAND, TIP and UBC). The programs identified no single gene that showed stable expression under all of the conditions tested, and the individual rankings of the genes differed between the algorithms. Nevertheless the new candidate genes, specifically, PP2A and UBC, were ranked higher as compared to the other traditional reference genes. In general, Tubulin showed the most variable expression and should be avoided as a reference gene. Conclusions: Reference genes evaluated as suitable in experiments with Arabidopsis thaliana were stably expressed in roses under various experimental conditions. In most cases, these genes outperformed conventional reference genes, such as EF1-α and Tubulin. We identified PP2A, SAND and UBC as suitable reference genes, which in different combinations may be used for normalisation in expression analyses via qPCR for different rose tissues and stress treatments. However, the vast genetic variation found within the genus Rosa, including differences in ploidy levels, might also influence expression stability of reference genes, so that future research should also consider different genotypes and ploidy levels.

25 de Abril para sempre? "Fascismo" nunca mais?

Nem está garantido que o “25 de Abril seja para sempre”. O mais certo é que não esteja. Nem está assegurado, qual verdade ontológica, que não haverá mais “fascismo” ou um outro “Estado Novo de inspiração fascista”, como alguns preferem descrever o período histórico vivido em Portugal entre 1933 (com raízes em 1928 após eleição de Óscar Carmona) e o 25 de Abril de 1974. O mais certo é que surjam novos tipos de “fascismo”. § Abstract: Neither is guaranteed that the "April 25th is forever." Most likely it is not. Neither is assured, what ontological truth, there will be no more "fascism" or another "New State of fascist inspiration," as some prefer to describe the historical period lived in Portugal between 1933 (with roots in 1928 after Óscar Carmona Election) and April 25, 1974. most likely there are new types of "fascism."

Walking Through the Revolution: A Spatial Reading of Literary Echoes

This paper presents an embryo of a literary guide on the Carnation Revolution to be explored for educational historical excursions other than leisure and tourism. We propose a historical trail through the centre of Lisbon, city of the Carnation Revolution, called Walk through the Revolution. The trail aims to reinforce collective memory about the major events that occurred in the early moments leading to the coup. The trail is made up by nine places of rememberance, for which literary excerpts are suggested and which are supported by a digital research procedure. A set of seven fixed and observer-independent categories are used to analyse the literary contents of 23 literary works published up to 2013. These literary works refer to events that happened between the eve of April 25 and May 1, 1974. At the same time, literary descriptions are explored using a spatial approach in order to define the literary geography of the most iconic military actions and popular demonstrations that occurred in Lisbon and the surroundings. The literary geography and the cartography of the historical events are then compared. Data analysis and visualization benefit from the use of standardised and quantitative methods, including basic statistics and geographic information systems.

Children at psychiatric risk and their families in Bucharest, in the context of 25 years of changes after December 89’ Romanian Revolution

The aim of the present dissertation was to capture a picture of child and adolescent mental health in Romania, in the context of almost 25 years of changes following the Romanian Revolution of December ’89. A three-part study was carried out in order to provide consistent answers to the pre-defined objectives: to appraise the development of child and adolescent mental health services in Romania (Part I), to explore the characteristics of clinically-referred patients in a Romanian child and adolescent psychiatry department (Part II), to examine the children’s mental health state and its connections with family functioning and associated risk factors (Part III). A multi-method research approach was used, comprising one qualitative analysis and two quantitative research studies. Part I consisted of a comparative qualitative analysis of the answers given by 10 mental health professionals at a 12-questions open ended interview about the current situation in child and adolescent mental health in Romania, on three topics: changes, challenges, solutions. Part II involved a descriptive quantitative analysis of certain variables (e.g. age, gender, primary diagnosis, co-morbidities, time of hospitalization) conducted on the patients who had been admitted to the Child and Adolescent Psychiatry Department at “Prof. Dr. Alexandru Obregia” Psychiatry Hospital, Bucharest in 1991 and in 2013. Part III was conducted on 342 subjects enrolled in two clinical groups and one school group, this study being performed through a cross-sectional analysis on multi-informant child and adolescent mental health problems and competencies (CBCL, YSR, SDQ P, SDQ SR) and their interrelation with household information (HQ) and family functioning (FAD). Outlining the results it can be stated that: 1) The CAMH System in Romania is definitely set on the path of reorganization, including a higher involvement of beneficiaries and of the community. 2) The characteristics of the admitted patients have changed significantly during the last almost 25 years since `89 December Revolution, under the influence of word wide trends in child psychiatry and of administrative aspects of the mental health network in Romania. 3) The rates of main diagnoses and co-morbidities confirm the reports in literature, with Autism Spectrum Disorder being the most frequent childhood psychiatric disorders in this study. 4) The children’s mental health problems in the psychiatry group are comparable to those reported for other clinical populations. 5) Significant score differences were observed according to various household features and also meaningful associations between a child’s clinical status and different aspects of family functioning. The Romanian Child and Adolescent Psychiatry has started to adopt the norms and standards of the European Union. In the 25 years that have elapsed after the 1989 Revolution, many changes have occurred in Romanian CAMH, but many unresolved issues have also risen. Therefore, the major contribution of this thesis is that it provides a coherent and updated overview of the present-day situation from three different perspectives- those of mental healthcare professionals, the one observed in clinical patients and the one reported by children’s families.

"The sound of democracy - the sound of freedom" - Jazz-Rezeption in Deutschland (1945 - 1963)

Im Mittelpunkt der Studie "The Sound of Democracy - the Sound of Freedom". Jazzrezeption in Deutschland (1945 - 1963) steht ein Korpus von 16 Oral-History-Interviews mit Zeitzeugen der deutschen Jazzszene. Interviewt wurden Musiker ebenso wie bildende Künstler, Journalisten, Clubbesitzer und Jazzfans, die die Jazzszene in den 1950ern bildeten. Die Interviews werden in einen Kontext zeitgenössischer Quellen gestellt: Zeitschriftenartikel (hauptsächlich aus dem "Jazz Podium" ebenso wie Radiomanuskripte des Bayerischen Rundfunks.rnDie Ausgangsüberlegung ist die Frage, was der Jazz für sein Publikum bedeutete, mit anderen Worten, warum wählte eine studentische, sich selbst als elitär wahrnehmende Schicht aus dem großen Fundus an kulturellen Ausdrucksformen, die nach dem Zweiten Weltkrieg aus den USA nach Deutschland strömten, ausgerechnet den Jazz als persönliche Ausdrucksform? Worin bestand seine symbolische Strahlkraft für diese jungen Menschen?rnIn Zusammenhang mit dieser Frage steht die Überlegung: In welchem Maße wurde Jazz als dezidiert amerikanische Ausdrucksform wahrgenommen und welche Amerikabilder wurden durch den Jazz transportiert? Wurde Jazz bewusst als Werkzeug der Besatzer zur demokratischen Umerziehung des deutschen Volkes eingesetzt und wenn ja, in welcher Form, beziehungsweise in welchem Maß? Wie stark war die Symbolleistung und metaphorische Bedeutung des Jazz für das deutsche Publikum und in welchem Zusammenhang steht die Symbolleistung des Jazz mit der Symbolleistung der USA als Besetzungs- bzw. Befreiungsmacht? rn

Design of an Advanced Platform for Citizen Participation Committed to Ensuring Freedom of Speech

This paper presents a proposal for an advanced system of debate in an environment of digital democracy which overcomes the limitations of existing systems. We have been especially careful in applying security procedures in telematic systems, for they are to offer citizens the guarantees that society demands. New functional tools have been included to ensure user authentication and to permit anonymous participation where the system is unable to disclose or even to know the identity of system users. The platform prevents participation by non-entitled persons who do not belong to the authorized group from giving their opinion. Furthermore, this proposal allows for verifying the proper function of the system, free of tampering or fraud intended to alter the conclusions or outcomes of participation. All these tools guarantee important aspects of both a social and technical nature, most importantly: freedom of expression, equality and auditability.

The future of human rights protection in the new Libya: prospects and challenges. Jean Monnet Occasional Paper No. 6/2014

There is no doubt that demand for the respect of human rights was one of the factors behind the Arab Spring and Libya is no exception. Four decades of absolute dictatorship headed by Muammar Gaddafi had been further tainted with gross violations of human rights of Libyan citizens and restrictions on their basic freedoms. Before the revolution, Libya was a country where no political parties were allowed. Freedom of expression and the press were extremely restricted. Reports about the country’s human rights violations published by a number of international organizations documented large scale human rights abuses at the hands of the Gaddafi regime. The 17 February 2011 revolution in Libya led to a turning point in the country’s history. The regime of Muammar Gaddafi which had dominated the country since 1969 eventually collapsed, leading to the beginning of the painful task of reconciliation and state building. Nonetheless it is estimated that more than 7000 prisoners are held captive by various militias and armed groups without due process. This in addition to thousands of internally displaced persons. State building involves the consolidation of a democratic state based on a democratic constitution. In 2011, a constitutional declaration was adopted to replace the one that had been in effect since 1969. This was intended as a stop-gap solution to allow the new political forces unleashed in the country time to write a new democratic constitution. To help consolidate the democratic state, three elements are required: that human rights be placed at its core; that these rights are truly implemented and applied; and lastly that the independence of the judiciary is safeguarded. For all this to happen it is also essential to strengthen education on human rights by encouraging non-governmental organizations to take a stronger role in promoting human rights. Libyan citizens can only avail themselves of these rights and strengthen their implementation if they know what they are and how they can benefit from their implementation

Kyrgyzstan: Balancing on the Verge of Stability. EUCAM Policy Brief No. 19, July 2011

Following the ‘revolution’ in April 2010, the subsequent interethnic violence in June and the recent international inquiry into these events, Kyrgyzstan is not in safe waters yet. The coming period leading up to the Presidential elections will be important for the country’s stability. What is the current situation in the South of the country, which saw clashes between Kyrgyz and Uzbeks, and what are the expectations for the presidential elections? Is Kyrgyzstan on the road to democracy, and what role can external actors play?
