Foundational Forensic Techniques for Cellular and Ad Hoc Multi-hop Networks

The Internet has become an integral part of our nation's critical socio-economic infrastructure. With its heightened use and growing complexity however, organizations are at greater risk of cyber crimes. To aid in the investigation of crimes committed on or via the Internet, a network forensics analysis tool pulls together needed digital evidence. It provides a platform for performing deep network analysis by capturing, recording and analyzing network events to find out the source of a security attack or other information security incidents. Existing network forensics work has been mostly focused on the Internet and fixed networks. But the exponential growth and use of wireless technologies, coupled with their unprecedented characteristics, necessitates the development of new network forensic analysis tools. This dissertation fostered the emergence of a new research field in cellular and ad-hoc network forensics. It was one of the first works to identify this problem and offer fundamental techniques and tools that laid the groundwork for future research. In particular, it introduced novel methods to record network incidents and report logged incidents. For recording incidents, location is considered essential to documenting network incidents. However, in network topology spaces, location cannot be measured due to absence of a 'distance metric'. Therefore, a novel solution was proposed to label locations of nodes within network topology spaces, and then to authenticate the identity of nodes in ad hoc environments. For reporting logged incidents, a novel technique based on Distributed Hash Tables (DHT) was adopted. Although the direct use of DHTs for reporting logged incidents would result in an uncontrollably recursive traffic, a new mechanism was introduced that overcome this recursive process. These logging and reporting techniques aided forensics over cellular and ad-hoc networks, which in turn increased their ability to track and trace attacks to their source. These techniques were a starting point for further research and development that would result in equipping future ad hoc networks with forensic components to complement existing security mechanisms.

HIP HOP COMO PROCESSO COMUNICACIONAL E SOCIABILIDADE PARA JOVENS INDÍGENAS DE DOURADOS – MS

Estudo sobre o Hip Hop como processo comunicacional e sociabilidade entre jovens indígenas de Dourados, Mato Grosso do Sul, para verificar quais os principais objetivos da prática do movimento Hip Hop, compreender se serve como comunicação, contribui para o fortalecimento da língua guarani ou gera novas tensões sociais na reserva. Para tanto, foi analisado aspectos históricos do movimento, passando pelos Estudos Culturais, e como Movimento Social, dando início à discussão de uma voz alternativa por meio do Hip Hop. Do ponto de vista metodológico, trata-se de um de estudo de caso, com representantes dos grupos de jovens Brô Mc's e Jovens Conscientes, das reservas Jaguapirú e Bororó, das etnias Guarani-Kaiowá de Dourados (MS). Foram realizadas entrevistas semiestruturadas junto a jovens que participaram das oficinas de hip hop, das lideranças indígenas e professores. A investigação é complementada pela pesquisa bibliográfica, documental e análises das letras de rap em confrontação com as visões da imprensa, a partir da análise dos jornais Diário MS e O Progresso. Os resultados apontam que os jovens se apropriam de uma cultura global para transformar o ambiente local com objetivo de preservar a língua guarani, uma alternativa para o conhecimento, logo para não seguirem caminhos como o das drogas. Negociando falas sobre sua realidade, dentro e fora da reserva, já que nos meios de comunicação locais há pouco espaço para a voz dos indígenas e dentro da reserva ainda há contestação do movimento em um contexto político, na tentativa de atingir uma cultura “pura”, devido à preocupação dos mais velhos com a perda de território.

Situación de la profesión de bibliotecario público en la Universidad de Mallorca (1770-1808)

La Universidad de Mallorca consigue en 1770, por donación real, las bibliotecas que habían formado los Jesuitas en sus colegios de Montesión y San Martín en Palma y el de San Ignacio en Pollença. El objetivo de este trabajo es estudiar a los bibliotecarios que van a estar al cargo de esta biblioteca, universitaria y pública, formada con la unión de las tres mencionadas bibliotecas. Se analizan también todas las solicitudes que se envían al rey Carlos III desde Mallorca para ocupar dicho cargo. La metodología utilizada ha sido la consulta de la documentación generada en la época y conservada en archivos históricos de Madrid y Palma. Los resultados de la investigación se pueden resumir en que la profesión de bibliotecario en la Mallorca de la segunda mitad del siglo XVIII tiene prestigio y está socialmente bien considerada.

Interpretation and typology Spanish indefinite pronoun uno in three discoursive genres

This study investigates the Spanish indefinite pronoun uno (“one”). After a detailed analysis of its occurrences in authentic language, we find that its interpretation varies depending on the linguistic context. Therefore, we examine which elements of the context - we focus on the broader context, beyond the sentence – have an impact on its interpretation and develop a typology of the indefinite pronoun as to its interpretation. The pronoun may be interpreted as completely generic or specific (referring to the speaker, the listener or a third person). Its interpretation can also be located in an intermediate position between these interpretive extremes.In addition, we compare its use in various discursive genres - spontaneous conversations, academic essays and web forum - which are distinguished by the presence or absence of interactivity and of more or less subjectivity / intersubjectivity. The comparison shows that pronoun use depends on these characteristics.

Multiuser dual-hop relaying over hybrid RF/FSO links

The performance of multiuser dual-hop relaying over mixed radio frequency/free-space optical (RF/FSO) links is investigated. RF links are used for the simultaneous data transmission from m single-antenna sources to the relay, which is equipped with n ≥ m receive antennas and a photo-aperture transmitter. The relay operates under the decode-and-forward protocol and utilizes the popular ordered V-BLAST technique to successively decode each user's transmitted stream. A common norm-based ordering approach is adopted, where the streams are decoded in an ascending order. After the V-BLAST decoding, the relay retransmits the initial information to the destination, which is equipped with a photo-detector, via a point-to-point FSO link in m consecutive timeslots. Analytical expressions for the end-to-end outage probability and average symbol error probability of each user are derived. Some engineering insights are manifested, such as the diversity order, the impact of the pointing error displacement on the FSO link and the severity on the turbulence-induced channel fading.

La réception du hip-hop chez des rappeurs afro-québécois dans la ville de Québec : appropriation intersectionnelle de problématiques multidimensionnelles

Cette thèse analyse les rappeurs afro-québécois des communautés de Limoilou (Limoilou Starz) et leurs amis de Montcalm comme des acteurs qui s’approprient des éléments identitaires, de lutte sociale et de survie économique, issus des problématiques globales et américaines du hip-hop, au service de leurs défis particuliers. Les divers mérites des luttes menées au moyen de leur art sont acquis par des formes spécifiques de capital. Ainsi les moyens utilisés par les rappeurs sont principalement les paroles de chansons, les prises de parole publique, dans les médias et sur scène, les campagnes d’affichage, l’utilisation des réseaux numériques, l’entreprise économique autonome (photographie, vidéographie, gestion des artistes, vente de vêtements). Ces moyens spécifiques se rattachent à d’autres principes et actions non explicités et sociohistoriquement ancrés. À partir d’une enquête ethnographique menée auprès de 31 participants dans la ville de Québec, j’utilise le concept de « réception différenciée » (Hall, 1980; Morley, 1980) pour décrire le processus de résistance des différents pratiquants et entrepreneurs de la musique aux dominations provenant de groupes divers. Trois principaux groupes de domination sont examinés : les agents d’institutions étatiques (comme les policiers du Service de Police de la Ville de Québec), les agents d’entreprises privées (comme les patrons de grandes boites de nuit et les propriétaires de labels musicaux indépendants) et les groupes et individus du milieu hip-hop, à travers leurs stratégies d’intimidation. La théorie « émergente » ou emergent-fit (Guillemette, 2006; Guillemette et Luckerhoff, 2009) permet d’entrevoir la musique hip-hop en amont comme une structure multidimensionnelle (sociale, identitaire, politique et économique) et intersectionnelle (intersection de plusieurs catégories interreliées, relatives au lieu de résidence, à la race et aux capacités économiques), et en aval comme un champ musical (Bourdieu, 1976 et 1989; Rimmer, 2010) renégocié. Cette structure a pris forme et s’est transformée grâce aux dispositions mentales et physiques (habitus) des acteurs étudiés. Les résultats de cette recherche montrent que certains rappeurs et leurs autres collègues artistes hip-hop— ainsi que quelques entrepreneurs— résistent à plusieurs sortes de domination. D’autres encore acceptent ces dominations sous forme d’idéologies, même en le reconnaissant explicitement. Par contre, une infime partie des acteurs étudiés les rejettent complètement. Ainsi, l’appropriation multidimensionnelle et intersectionnelle des sens dominants à travers le hip-hop mène à plusieurs formes de lecture de la domination et de la résistance.

Primer registro de ocurrencia de Helicoverpa armigera (Hübner, 1808) (Lepidoptera: Noctuidae) en soja, en Uruguay

Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) es una especie polífaga, con estatus de plaga cuarentenaria en Uruguay, que ha sido registrada en Europa, Asia, África, Oceanía, y más recientemente, en los países vecinos de América del Sur. Este es el primer registro confirmado de H. armigera en cultivos de soja, en Uruguay. La identificación de esta especie es difícil por su proximidad taxonómica con otras especies de los géneros Helicoverpa y Heliothis. La confirmación de identificación se realizó mediante caracteres anatómicos externos y de las genitalias, así como estudio de ADN, en machos adultos capturados en trampas de feromona sexual y larvas criadas en laboratorio, recolectadas en cultivos de soja en cuatro localidades de Flores, Lavalleja, Cerro Largo y Rocha.

Alexandre Jose de Melo Moraes (1816-1882), foi medico Historiador e politico brasileiro. Revela-se como autor de um Compêndio de historia no ano de 1854, quando publica a obra Ensaio corografico do imperio do Brasil. O sucesso da obra levou-o a mudar radicalmente o rumo de seu interesse de assuntos tão diversos como a Medicina, Botanica e Agricultura para a Historia. Mello Moraes não tinha formação de historiador nem jamais se dedicara a pesquisa historica, porem legou seu nome a posteridade como um dos maiores amealhadores de documentos historicos relevantes. Sua obra e recheada de preocupações politicas assemelhou a tarefa de historiador a de um juiz que censura, mostra os defeitos, acusa os crimes ou louva as virtudes para a posteridade. Foi considerado um Grande colecionador e pesquisador.
