Creació de material en format vídeo com a suport a les assignatures de matemàtiques
Aquest projecte és la segona etapa d’un projecte iniciat el curs passat. Seguint la
filosofia de l’EEES pretenem crear materials en format vídeo enfocats a facilitar el
treball de l’estudiant i a millorar el seu procés d’aprenentatge. Generemexercicis que es
plantegin als nostres estudiants en el Campus Atenea i que una vegada pensats i resolts
per aquests se’ls proporcioni la resolució en format vídeo (junt amb el PDF de la
resolució). Aquesta resolució amb el format vídeo fa que sigui més propera a aquests
estudiants que estan immersos de petits en els formats que proporcionen les TIC. La
utilització d’aquest material és diversa: com a eina a un curs que s’està fent, com a eina
d’autoaprenentatge, com a eina de refresc en assignatures que utilitzen aquests
conceptes, etc. Per tant aquest usos poden tenir molt bon paper a l’atenció a la
progressió dels estudiants mitjançant el suport d’aquestes metodologies actives.
La primera etapa del projecte ha culminat amb la realització de 12 vídeos utilitzats en
les assignatures de matemàtiques del pla 92 i la segona etapa, amb 12 vídeos més,
incorpora les assignatures dels graus. Les enquestes mostren la satisfacció de
l’estudiantat en l’ús d’aquests vídeos.Peer Reviewe
Past and present taxonomy of the Liolaemus lineomaculatus section (Liolaemidae): is the morphological arrangement hypothesis valid?
Twenty-one species of lizards are included in the southernmost clade of South America, the Liolaemus lineomaculatus section. There are two hypotheses of species-grouping within this section, one based on morphological similarities and the other based on molecular phylogenetic relationships; although discordant, both are in use. The ‘morphological arrangement hypothesis’, which sorts the species of the section in three groups, was proposed ~30 years ago; however, despite taxonomic changes and almost doubling the species diversity of this section since then, the hypothesis has never been tested. Here, we (1) present an updated chronological review of taxonomic changes, species descriptions, morphological groups, and genetic clades proposed for the L. lineomaculatus section, and (2) evaluate the accuracy of the ‘morphological arrangement hypothesis’. We show that the traditional practice of classifying 11 of these species in two of the three traditional morphological groups of the section (Liolaemus kingii and Liolaemus archeforus), which is not supported by molecular data, is also not supported by morphological data, and therefore should be abandoned; we suggest referring to this group of species as the L. kingii group. We characterized the Liolaemus magellanicus group based on morphology, and extend the previously published morphological characteristics of the L. lineomaculatus group. Finally, we comment on future prospects for studies of sexual dimorphism and its possible ecological implications. This paper provides a critical synthesis of our understanding of the morphological and phylogenetic patterns within the L. lineomaculatus section and presents a useful framework for future tests of taxonomic hypotheses and physiological, behavioural, and evolutionary questions within this sectionFil: Breitman, Maria Florencia.

Queer Futurity and Hybridity in "Arrival" and "Embrace of the Serpent"
This thesis explores how the queered, racialized, and Othered groups in the films Arrival and Embrace of the Serpent are seen by hegemonic culture as an infection. Their infection is established through the preventative actions used by hegemonic culture which differ in each film and include anything from inoculations to forced assimilation. Despite preventative actions, members of hegemonic culture who venture into the Other’s environment can still become sick due to contact and must embrace the cultural practices of the Other in order to survive, suggesting that queerness is incompatible with normativity. Utilizing queer analytics such as opacity, temporal mis-orientations, and dreams, this thesis examines the circular logic of how the queerness of the Other’s environment is tied to what constructs them as queer. As such, members of hegemonic culture must embrace queer cultural practices in order to survive in these queer environments. In Arrival this means learning the Heptapods language and non-normative temporality, while in Embrace of the Serpent this means understanding Indigenous, land-based cultural practices. Some become hybrids between queer and hegemonic culture, while others become infected by the Other and do not survive. At the end of both films the queer Other disappears, leaving the hybrid behind with the knowledge necessary to preserve the Other’s culture. This thesis poses questions about queer futurity, or ability of queer populations to survive, and whether or not the queer Other has a future, looking closely at the queer, racialized Other. Drawing on the work of Jose Esteban Muñoz, I argue that the Heptapods in Arrival and the Indigenous people in Embrace of the Serpent reflect Muñozian understandings of queer futures as being ephemeral, especially because the components that mark the queered groups as illegible coexist with their choice to leave their cultural knowledge behind before they disappear
The murine cataractogenic mutation, Cat Fraser, segregates independently of the gamma crystallin genes
The murine mutation, Cat Fraser (Cat(Fr)), causes dominantly inherited ocular cataracts. Lenses of adult mice bearing this mutation contain reduced amounts of all seven γ-crystallin proteins and their corresponding transcripts. Levels of other lens proteins and transcripts appear normal and no extra-ocular effects of the mutation have been observed. The selective effect of this mutation on the γ-crystallins is consistent with the possibility that the site at which it occurs is involved in the coordinated regulation of the family of genes which encodes them. We have shown that several restriction fragment length polymorphisms in the γ-crystallin genes segregate independently of the Cat(Fr) mutation. Therefore, despite its selective effect on the expression of the γ-crystallin genes, the mutation is not linked to them. This observation rules out the possibility that the mutation is in a cis-acting regulatory site.published_or_final_versio
Adaptive development and maintenance of user-centric software systems
A software system cannot be developed without considering the various facets of its environment. Stakeholders – including the users that play a central role – have their needs, expectations, and perceptions of a system. Organisational and technical aspects of the environment are constantly changing. The ability to adapt a software system and its requirements to its environment throughout its
full lifecycle is of paramount importance in a constantly changing environment. The continuous involvement of users is as important as the constant evaluation of the system and the observation of evolving environments. We present a methodology for adaptive software systems development and
maintenance. We draw upon a diverse range of accepted methods including participatory design, software architecture, and evolutionary design. Our focus is on user-centred software systems
Liolaemus baguali (NCN): Spinal injury
Liolaemus baguali is an uncommon liolaemid lizard endemic to Patagonian steppe environments of western Santa Cruz Province, southern Patagonian, Argentina. During field work on 17 January 2008, along the margins of Ruta Nacional (National Highway) 40, 72.8 km N of its junction Ruta Provincial (Provincial Highway) 288 (49.1040°S, 71.1985°W; datum WGS84; elev. 525 m), Rio Chico Department, Santa Cruz Province, we collected an adult male L. baguali (66.4 mm SVL) that appeared to exhibit a scoliosis as had been recently reported for another Patagonian lizard (Frutos et al. 2006. Herpetol. Rev. 37 468469).Fil: Feltrin, Natalia. Consejo Nacional de Investigaciones Científicas y Técnicas. Centro Nacional Patagónico; ArgentinaFil: Perez, Cristian Hernan Fulvio.

Coalescent-based species delimitation in the sand lizards of the Liolaemus wiegmannii complex (Squamata: Liolaemidae)
Coalescent-based algorithms coupled with the access to genome-wide data have become powerful tools forassessing questions on recent or rapid diversification, as well as delineating species boundaries in the absence of reciprocal monophyly. In southern South America, the diversification of Liolaemus lizards during the Pleistocene is well documented and has been attributed to the climatic changes that characterized this recent period of time. Past climatic changes had harsh effects at extreme latitudes, including Patagonia, but habitat changes at intermediate latitudes of South America have also been recorded, including expansion of sand fields over northern Patagonia and Pampas). In this work, we apply a coalescent-based approach to study the diversification of the Liolaemus wiegmannii species complex, a morphologically conservative clade that inhabits sandy soils across northwest and south-central Argentina, and the south shores of Uruguay. Using four standard sequence markers (mitochondrial DNA and three nuclear loci) along with ddRADseq data we inferred species limits and a time calibrated species tree for the L. wiegmannii complex in order to evaluate the influence of Quaternary sand expansion/retraction cycles on diversification. We also evaluated the evolutionary independence of the recently described L. gardeli and inferred its phylogenetic position relative to L. wiegmannii. We find strong evidence for six allopatric candidate species within L. wiegmannii, which diversified during the Pleistocene. The Great Patagonian Glaciation (∼1 million years before present) likely split the species complex into two main groups: one composed of lineages associated with sub-Andean sedimentary formations, and the other mostly related to sand fields in the Pampas and northern Patagonia. We hypothesize that early speciation within L. wiegmannii was influenced by the expansion of sand dunes throughout central Argentina and Pampas. Finally, L. gardeli is supported as a distinct lineage nested within the L. wiegmannii complex.Fil: Villamil, Joaquín. Universidad de la República.

From right to written : an inquiry into the codification of a right to data
Award date: 17 June 2022. Supervisor: Professor Madeleine De Cock Buning, EUI School of Transnational GovernanceThis thesis analyses Brazil’s Lei Geral de Proteção de Dados, and Marco Civil da Internet in an attempt to answer the question: "to what extent is the right to Data Protection entrenched in Brazilian legislation?”. The investigation applies a black letter analysis approach to the laws, surveying the values at the their foundation, the systems they put in place, and the procedural tools made available within that system. It concludes that while the values contained in the laws are consistent with a right to data protection, and the systems built give a strong framework for application, the right is jeopardized by a politicization of procedural tools
