Das raízes

O objetivo deste projeto artístico foi desenvolver um conhecimento mais aprofundado relacionado com a execução e interpretação de técnicas de percussão tradicionais aliadas a técnicas contemporâneas. De entre as várias técnicas tradicionais de percussão optei por desenvolver as da percussão Africana (Guiné e Burkina Faso, e mais tarde Nigéria) e as da percussão Cubana. Criei assim um projeto artístico de fusão intitulado Das Raízes, no qual ao longo dos dois anos do curso de mestrado estive em contacto com a música Africana e Cubana aliada a técnicas contemporâneas e composições originais (minhas e de outros compositores). Para cada obra explorei primeiro as técnicas tradicionais e em seguida adaptei-as à percussão contemporânea, num processo onde as suas raízes africanas, cubanas ou até afro- cubanas são evidentes. Neste projeto salienta-se o papel preponderante das mãos. No século XXI o uso da baqueta predomina como a técnica mais forte para dominar os instrumentos nos conservatórios e nas escolas superiores de música. Após ter adquirido esta técnica resolvi aprofundar as técnicas tradicionais onde predominam o uso não só da baqueta mas também da mão, um mundo antigo na sua existência, mas novo para mim. Espero poder transportar o ouvinte para um mundo em que cor, movimento e som, antiguidade e contemporaneidade estão em constante vibração.

Exploration génétique de l'hypothyroïdie congénitale par dysgénésie thyroïdienne

L'hypothyroïdie congénitale par dysgénésie thyroïdienne (HCDT, ectopie dans plus de 80 %) a une prévalence de 1 cas sur 4000 naissances vivantes. L’HCDT est la conséquence d'une défaillance de la thyroïde embryonnaire à se différencier, à se maintenir ou à migrer vers sa localisation anatomique (partie antérieure du cou), qui aboutit à une absence totale de la thyroïde (athyréose) ou à une ectopie thyroïdienne (linguale ou sublinguale). Les HCDT sont principalement non-syndromiques (soit 98% des cas sont non-familiale), ont un taux de discordance de 92% chez les jumeaux monozygotes, et ont une prédominance féminine et ethnique (i.e., Caucasienne). La majorité des cas d’HCDT n’a pas de cause connue, mais est associée à un déficit sévère en hormones thyroïdiennes (hypothyroïdie). Des mutations germinales dans les facteurs de transcription liés à la thyroïde (NKX2.1, FOXE1, PAX8, NKX2.5) ont été identifiées dans seulement 3% des patients atteints d’HCDT sporadiques et l’analyse de liaisons exclue ces gènes dans les rares familles multiplex avec HCDT. Nous supposons que le manque de transmission familiale claire d’HCDT peut résulter de la nécessité d’au moins deux « hits » génétiques différents dans des gènes importants pour le développement thyroïdien. Pour répondre au mieux nos questions de recherche, nous avons utilisé deux approches différentes: 1) une approche gène candidat, FOXE1, seul gène impliqué dans l’ectopie dans le modèle murin et 2) une approche en utilisant les techniques de séquençage de nouvelle génération (NGS) afin de trouver des variants génétiques pouvant expliquer cette pathologie au sein d’une cohorte de patients avec HCDT. Pour la première approche, une étude cas-contrôles a été réalisée sur le promoteur de FOXE1. Il a récemment été découvert qu’une région du promoteur de FOXE1 est différentiellement méthylée au niveau de deux dinucléotides CpG consécutifs, définissant une zone cruciale de contrôle de l’expression de FOXE1. L’analyse d’association basée sur les haplotypes a révélé qu’un haplotype (Hap1: ACCCCCCdel1C) est associé avec le HCDT chez les Caucasiens (p = 5x10-03). Une réduction significative de l’activité luciférase est observée pour Hap1 (réduction de 68%, p<0.001) comparé au promoteur WT de FOXE1. Une réduction de 50% de l’expression de FOXE1 dans une lignée de cellules thyroïdienne humaine est suffisante pour réduire significativement la migration cellulaire (réduction de 55%, p<0.05). Un autre haplotype (Hap2: ACCCCCCC) est observé moins fréquemment chez les Afro-Américain comparés aux Caucasiens (p = 1.7x10-03) et Hap2 diminue l’activité luciférase (réduction de 26%, p<0.001). Deux haplotypes distincts sont trouvés fréquemment dans les contrôles Africains (Black-African descents). Le premier haplotype (Hap3: GTCCCAAC) est fréquent (30.2%) chez les contrôles Afro-Américains comparés aux contrôles Caucasiens (6.3%; p = 2.59 x 10-9) tandis que le second haplotype (Hap4: GTCCGCAC) est trouvé exclusivement chez les contrôles Afro-Américains (9.4%) et est absent chez les contrôles Caucasiens (P = 2.59 x 10-6). Pour la deuxième approche, le séquençage de l’exome de l’ADN leucocytaire entre les jumeaux MZ discordants n’a révélé aucune différence. D'où l'intérêt du projet de séquençage de l’ADN et l’ARN de thyroïdes ectopiques et orthotopiques dans lesquelles de l'expression monoallélique aléatoire dans a été observée, ce qui pourrait expliquer comment une mutation monoallélique peut avoir des conséquences pathogéniques. Finalement, le séquençage de l’exome d’une cohorte de 36 cas atteints d’HCDT a permis d’identifier de nouveaux variants probablement pathogéniques dans les gènes récurrents RYR3, SSPO, IKBKE et TNXB. Ces quatre gènes sont impliqués dans l’adhésion focale (jouant un rôle dans la migration cellulaire), suggérant un rôle direct dans les défauts de migration de la thyroïde. Les essais de migration montrent une forte diminution (au moins 60% à 5h) de la migration des cellules thyroïdiennes infectées par shRNA comparés au shCtrl dans 2 de ces gènes. Des zebrafish KO (-/- et +/-) pour ces nouveaux gènes seront réalisés afin d’évaluer leur impact sur l’embryologie de la thyroïde.

Faulkner revisited : narrating property, race, gender and history in William Faulkner's Go Down, Moses, Toni Morrison's Song of Solomon and Gloria Naylor's Mama Day

My thesis explores the formation of the subject in the novels of Faulkner’s Go Down, Moses, Toni Morrison’s Song of Solomon, and Gloria Naylor’s Mama Day. I attach the concept of property in terms of how male protagonists are obsessed with materialistic ownership and with the subordination of women who, as properties, consolidate their manhood. The three novelists despite their racial, gendered, and literary differences share the view that identity and truth are mere social and cultural constructs. I incorporate the work of Judith Butler and other poststructuralist figures, who see identity as a matter of performance rather than a natural entity. My thesis explores the theme of freedom, which I attached to the ways characters use their bodies either to confine or to emancipate themselves from the restricting world of race, class, and gender. The three novelists deconstruct any system of belief that promulgates the objectivity of truth in historical documents. History in the three novels, as with the protagonists, perception of identity, remains a social construct laden with distortions to serve particular political or ideological agendas. My thesis gives voice to African American female characters who are associated with love and racial and gender resistance. They become the reservoirs of the African American legacy in terms of their association with the oral and intuitionist mode of knowing, which subverts the male characters’ obsession with property and with the mainstream empiricist world. In this dissertation, I use the concept of hybridity as a literary and theoretical devise that African-American writers employ. In effect, I embark on the postcolonial studies of Henry Louise Gates, Paul Gilroy, W. E. B Du Bois, James Clifford, and Arjun Appadurai in order to reflect upon the fluidity of Morrison’s and Naylor’s works. I show how these two novelists subvert Faulkner’s essentialist perception of truth, and of racial and gendered identity. They associate the myth of the Flying African with the notion of hybridity by making their male protagonists criss-cross Northern and Southern regions. I refer to Mae Gwendolyn Henderson’s article on “Speaking in Tongues” in my analysis of how Naylor subverts the patriarchal text of both Faulkner and Morrison in embarking on a more feminine version of the flying African, which she relates to an ex-slave, Sapphira Wade, a volatile female character who resists fixed claim over her story and identity. In dealing with the concept of hybridity, I show that Naylor rewrites both authors’ South by making Willow Springs a more fluid space, an assumption that unsettles the scores of critics who associate the island with authenticity and exclusive rootedness.

Safety assessment in primary Mycobacterium tuberculosis smear microscopy centres in Blantyre Malawi: a facility based cross sectional survey

Introduction Tuberculosis (TB) is caused by Mycobacterium tuberculosis and is transmitted mainly through aerosolization of infected sputum which puts laboratory workers at risk in spite of the laboratory workers’ risk of infection being at 3 to 9 times higher than the general public. Laboratory safety should therefore be prioritized and optimized to provide sufficient safety to laboratory workers. Objective To assess the safety for the laboratory workers in TB primary microscopy centres in Blantyre urban. Methodology TB primary microscopy centers in Blantyre urban were assessed in aspects of equipment availability, facility layout, and work practice, using a standardized WHO/AFRO ISO 15189 checklist for the developing countries which sets the minimum safety score at ≥80%. Each center was graded according to the score it earned upon assessment. Results Only one (1) microscopy center out nine (9) reached the minimum safety requirement. Four (4) centers were awarded 1 star level, four (4) centers were awarded 2 star level and only one (1) center was awarded 3 star level. Conclusion In Blantyre urban, 89% of the Tuberculosis microscopy centers are failing to provide the minimum safety to the laboratory workers. Government and other stake holders should be committed in addressing the safety challenges of TB microscopy centres in the country to ensure safety for the laboratory workers. Recommendations It is recommended that the study be conducted at the regional or national level for both public and private laboratories in order to have a general picture of safety in Tb microscopy centres possibly across the country.

Identidade, memória e narrativas na dança de São Gonçalo do povoado Mussuca (SE)

This study deals with the participation of the dance of São Gonçalo of the Mussuca town/SE, in the process of construction of the ethnic identity among this social group. The Mussuca is a grouping recognized as afro-descendents, linked with black enslaved people in the valley of the Cotinguiba region. The collective memory functions as a drive of this linking with the past and if it makes to elaborate narratives on this descent. The objective of this study was to investigate the ways the rite went through to constitute itself as an element of ethnic representation. Internal and external agents had been identified who had participated in different contexts. By means of an ethnographic work we ve reached some aspects of the local structure social which demonstrated the contradictions through the social relations of the group. This process of ethnic autorecognition presents the kinship and the space question as definers of the social arrangements which establish its ethnic boundaries

Negros misturados: um estudo de caso sobre identidades negras em Mossoró-RN

With more or less 213.000 habitants, Mossoró is the second more developed city from the Rio Grande do Norte. The town is proclamated like the land of freedom. To so far, exist four moments in your history related with the defence of freedom that is point like truthful from so proclamation. Suchlike happenings are the first female vote on Brazil, the resistance against the Lampião s band, the worman s mutiny and the slave release in 1883, five year before the Áurea law sanction. These happenings are commemorate yearly on setember with one big theatrical event called by the freedom high. Inside this contexto of exaltation to freedom, there is one black movement by name black and beautiful. Is the present dissertation, talked about the building of black identities between the black militants of Mossoró and the dwellers from the Santo Antônio district. With such approach, we intend to think about possibles differences or likeness, how the militants and dwellers from the refered district self-calleds like blacks or not. We are understanding black identity like one process to self-affirmation done by specificities of the social context and the individual particularity. This way, the identity change into one dynamic and contextual reality, gone always by one business process against the interaction of the social actors. So we search to discuss the specificities that involve the process to building of black identities in the city of freedom

Evolution of factors affecting mechanical olive harvesting

Harvest efficiency is defined as the percentage of fruits harvested by total production. The percentage of fruits harvested is less than 100% when working with trunk shakers to detach olives. It is important to increase the percentage of fruits harvested in order to increase farmer’s income. This objective can be achieved knowing the evolution of the main factors affecting fruit detachment. Fruit removal force (FRF), fruit weight (P) and the ratio between them are important for harvest efficiency. Field trials took place for two years (2013-2014) in Vilariça Valley, northeast Portugal in an olive orchard with ‘Cobrançosa Transmontana’ cultivar. It was adopted a mechanical harvesting system based on a trunk shaker to detach fruits, and an inverted umbrella to collect fruits. Elementary operation times were measured in seconds to evaluate work rates. FRF and P were measured in the ripening period, to evaluate their evolution. In this paper are presented the preliminary results of the ratio FRF (fruit removal force)/fruit weight evolution during the ripening period (P) and the results of the equipment work rate (trees h-1). The ratio FRF/P has predominantly descendant values in the weeks before harvest, from 140 to 80 as a result of a FRF downward variation from 4.9 to 2.94 N and an upward variation of P from 0.0294 to 0.0637 N. The FRF/P ratio stabilizes the decline in the last week of November just before harvesting, registering in some cases a slight increase in consequence of FRF increase higher than P increase (contrary to the tendency of previous weeks). Equipment work rate showed values between 40 and 57 trees h-1, confirming previous results.

Os exus em casa de catiço : etnografia, representações, magia

This dissertation is the result of an ethnographic journey undertaken in three spiritual centers of Umbanda , located in different districts of Natal/RN. The aim of the study was to understand how the representations of exus (spirit category) are established in the studied religious environment. In order to study this, mythical narratives of songs and of people were analyzed. In addition, the incorporated spirit entities, loaded with codes and values, were possible to be read and understood. The present work was developed according to a theoretical and methodological approach that interprets culture as a constant construction process, with representations and significations. The empirical research focuses on the ethnographic observations and the narratives; providing the experimentation of the models of discursive dialogues and polyphony. It was observed that the studied empirical field is marked by the cult of the Jurema which influences the mythical construction of exus . Therefore, this study enabled a reflection on the meeting of notions of two distinct worlds ( Umbanda and Jurema ). This reflection is crucial to the understanding of the position that exus occupy in the local umbandista system

Evidence of Discrimination Against Afrocolombians in the Colombian Labor Market in Major Cities in 2007

This paper evaluate the hypothesis that race is a determining factor in access to quality employment in Colombia during 2007 -- Using data from the Large Integrated Household Survey (2007-I), we estimate a generalized ordered logit model -- The results provide evidence that individuals self-identified as Afrocolombian have a higher probability of being in a low quality job than other Colombians -- This probability is higher by 1.9% in Cali, 3.4% in Bogotá, 12.6% in Barranquilla, 1.8% in Cartagena, 1.1% in Medellin and 3.8% overall in these five cities, results that could indicate that there is racial discrimination against Afrocolombians in the Colombian labor market

Nego veio é um sofrer : uma etnografia da subalternidade e do subalterno numa irmandade do Rosário

The object of this work is a fellowship of São Sebastião e Nossa Senhora do Rosário in the city of Jardim do Seridó (RN), that is, a black catholic fellowship on the sertão potiguar. The devotion to Nossa Senhora do Rosário, in colonial Brazil, organizes itself through black catholic men as fellowships. They blossomed in Brazil until the abolition, getting support from the Catholic church, from owners of slaves and from the population in general − unlike others afro-Brazilian religious expression. Today, these fellowships remain active, against the sentimental pessimism of the folklore studies, and they also have a highlight position in the calendar of many cities in Brazil, and in particular in Seridó. The research s foothold is the apparent valorization of the fellowship by the local elite, attitude that hides asymmetric relationships between the group of negros do Rosário and the local authorities, having as its consequence that the members occupy a subaltern position inside their own fellowship. This subalternity take place, mainly, in the public area, where the negros do Rosário cannot represent themselves neither political nor discursively. To discuss this idea, it s done a brief historical of these catholic institutions as well as a description of the relationship between the negros do Rosário and the elites of the city. Then, the phenomenon is analyzed as folklore and/or religion , under the perspective of many agents that participate in this process. In other moment, it is going to be presented how the group formulates their own representation of the history, of the devotional forms and of their own political-religious experiences. In this sense, an ethnography of the subalternity is understood as an analysis of the process that leads the negros do Rosário to become a subaltern group. It s also outlined the perception that the group has of its own position, through an ethnography essay of the subaltern subject. The research, focused in the group of Rosário, was done between August 2010 and January 2012 and includes other agents (like treasurers, priests and intellectuals). Besides that, as a methodological complement, there are documental research, photography, as well as shoots of the party days and public presentation

O Ofício das Rezadeiras: um estudo antropológico sobre as práticas terapêuticas e a comunhão de crenças em Cruzeta/RN

The present Master´s dissertation aims to study the practices of the rezadeiras, Brazilian women healers, through an anthropological perspective. Special attention will be given to the understanding of these practices as a dynamic process in relation to those women who heal in Cruzeta (Seridó, Rio Grande do Norte), where is located our ethnographic research. For this research, twenty four rezadeiras were contacted and colaborated with our work plan. Among them, two were pentecostal rezadeiras and another one was member of the Jurema cult, an afro-brazilian religious cult. Similarities among these women healers were perceived in the research process, mostly in terms of their learning process and the use of certain objects and ritual techniques. However, apparent differences among them gave us the chance for understanding and reflecting on the actual heterogeneity of this world of specialists. Furthermore, i tried to capture the relations between the rezadeiras and the therapeutic practices from health professionals or the religious practices of religious leaders (Catholic, pentecostal, etc). It is possible to ascertain about the complementarity between therapeutic practices from different cultural logics. This complementarity is also perceived through the religious interchanges and transits among different healers, including those who have different religious beliefs. In this work, rituals are also described and they are a crucial factor to the understanding of this particular religious and therapeutic practice conducted by women. Following these ideas, our basic aim is to understand how the rezadeiras make interpretations about health and illness, specially those ones which are particular associated with their practices, the so called "doenças de rezadeiras"

IV Cimeira UE-África

Em 2 e 3 de Abril teve lugar a Cimeira União Europeia-África tendo como principais pontos da agenda o investimento sobre as pessoas, a prosperidade e a paz e segurança. Este artigo analisa as fases preparatórias que precederam a Cimeira UE-África e examina os aspetos que geraram maior tensão durante o período de negociações que a antecedeu, tais como: os acordos de parceria económica e a posição do Tribunal Penal Internacional no que respeita à aplicação da justiça internacional e os regimes de direitos das minorias. Este contributo reflete ainda sobre os aspetos institucionais e sobre a complexa divisão de competências entre as várias instâncias europeias, no que respeita à organização daquele evento. Finalmente, examina os resultados da Cimeira, designadamente os alcançados sobre o domínio da paz e segurança, sobre a aplicação de regimes internacionais de direitos humanos, sobre as questões decorrentes das alterações climáticas e sobre o acordo afro-europeu no quadro da cooperação técnico-científica.

Layered workflow scheduling algorithm

Workflow applications require workflow processing in which workflow tasks are processed based on their dependencies. With the emergency of complex distributed systems such as grids and clouds, efficient workflow scheduling (WFS) algorithms have become the core components of the workflow management systems (WfMS). Thus, WFS that allocates each task in the workflow to a relevant resource with the aim of improving system performance and end user satisfaction is fundamentally important. In this paper, we propose a new workflow scheduling algorithm called Layered Workflow Scheduling Algorithm (LWFS) for scheduling workflow applications. We studied the efficacy of the LWFS scheduling experimentally and compared its performance with approaches including Improved Critical Path using Descendant Prediction (ICPDP), Highest Level First with Estimated Time (HLFET), Modified Critical Path (MCP) and Earliest Time First (ETF). The results of the experiments show that the proposed approach outperforms other approaches.
