O nascimento de uma política pública: das articulações à formulação do PRONERA

This work aims at reconstructing the formulation process of PRONERA (National Program of Education in Agrarian Reform). A public policy that had its first ideas conceived within social movements and afterwards, made possible by diligences of then government. Therefore, the Program was rendered in a partnership among State, social movement, public institutions, and non-governmental organizations. As a goal, we intend to grasp both what motivated the choice for this proposal as a strategy to face educational problems in rural areas and how the actors, entities involved in this enterprise and the social-political context have influenced its formulation and entry in the governmental agenda as Public Policy. Thus, we reconstruct the history and education policy of and in rural areas. Besides, we seek to understand the context of PRONERA's conception, the factors that have influenced its creation and the actors' performances in the process. It is assumed that under the 1988 Constitution, civil society was provided with legal conditions for the active participation in political process and, consequently, in the public policy-making. We conclude, then, that PRONERA was the result of the crossing of three different flows (problems, solutions and policies) advocated by the Kingdon model. As a result, this analytical repertoire was useful to explain PRONERA’s entry in the government agenda, helping to understand how the chances of this social demand increased with an action from the politic community. It allowed its way in the government agenda as well as its becoming a public policy.

Parâmetros biológicos de Herpsilochmus pectoralis Sclater 1857 (Aves: Thamnophilidae) em fragmentos de mata atlântica do Nordeste do Brasil

The study of birds represents an important tool for the understanding of the processes involved in behavioral and morphological patterns. The species we have studied belongs to Thamnophilidae family, the third largest family restricted to the Neotropic ecozone. They are popularly known as antbirds and comprise 209 species. A large portion of the species has cryptic behavior, making the acoustic communication an important tool for maintaining contact among birds. Herpsilochmus pectoralis Sclater 1857 has evident sexual dimorphism, measured between 10 and 12 cm height and it is found in forest fragments in the Northeast and it is also categorized as vulnerable to extinction process. This study was conducted in three sandbank fragments on the east coast of the state of Rio Grande do Norte, Brazil. With the help of tape recordings between 2006 and 2012 it was possible to describe and characterize the sing of H. pectoralis. The sing from male birds has more and longer length than the female sing (16% of dimorphism). No differences were found in the dominant frequency between the sexes. We describe four types of calls from this species repertoire. Through capturing with ornithological nets between 2009 and 2012 it was possible to describe and compare the morphology of H. pectoralis. The species have shown lower corporal mass in the dry season. The young birds showed morphometric similarities in comparison to adults. The species has no accentuated dimorphism in their morphometric characteristics. The young ones with flying capabilities have morphometric characteristics of adults, even though they do not show a characteristic adult plumage. The moult pattern in the species is a characteristic of tropical birds, but it shows short reproductive period, typical of temperate species. Even being in the tropical region, the species suffers with seasonal rainfall, which influences their reproductive phenology and moult (remex and rectrix) cycle. Thus, this dissertation provides information on the biology of H. pectoralis to support the understanding of the relationship of this species to the environment and also to know the variations of morphology and vocal aspects, in order to understand patterns and general characteristics of Thamnophilidae.

Sept Papillons de Kaija Saariaho: uma análise dos elementos técnico-interpretativos

Sept Papillons by Kaija Saariaho is a relevant piece in the contemporary cello repertoire. This research aims to study the context of the piece and approaches the technical and musical challenges presented in the work. As a methodological procedure, authors like MOISALA (2009) and VICTORIO (2015) were studied, giving basis to the understanding of the compositional process and to the analysis of the gestures proposed by the composer. Following, an interview was carried out with Natasha Farny, a cellist recognized for her performance of the work and utilized as reference, together with the Korean cellist Seung Ri Jung´s performance and the recording of Anssi Karttunen, to whom the piece was dedicated. Whilst the research of the bibliographical material and the interviews were taking place, the piece was studied and performed at the Masters of Music Program at UFRN. The experience obtained by the recitals and the research resulted in suggestions for cellists interested in its study and performance.

A TV como objeto de leitura da imagem no contexto escolar: uma pesquisa-ação com alunos do ensino médio

This research seeks to reflect on the dynamics of television reception, studying the Brazilian TV miniseries Hoje é Dia de Maria, produced by Globo Television Network, and aims to generally promote inferences in the process of image reading, mainly for aesthetic reading in school context, aiming at the formation of visual proficient readers. The research was conducted with students from the third grade of a state high school, geographically located in the city of Natal, Rio Grande do Norte. The theoretical framework comes from the assumptions of cognitive social interactionism to understand language, and it is also based on the ideas of Bakhtin (1992) and Vygotsky (1998), which enabled us to understand the social interaction and the Theory of Aesthetics Reception and Aesthetic Effect with Jauss (1979) and Iser (1999), which provided a better understanding of aesthetic experience, aesthetic effects and production of meaning. The methodological approach assumes a qualitative nature and an interpretive bias, accomplished through interviews, observation, questionnaire and application of a set of investigative activities, such as introductory exposition of themes, handing out of images and mediation process. This research is the result of a research-action process in a pedagogical intervention in a state school. The results indicate that the interactional linguistic resources used by the speakers demonstrated lack of prior knowledge and repertoire regarding image reading, which initially led them to do a cursory reading. It was evident that the respondents were unaware of the initial proposal. However, throughout the meetings, it was possible to realize their transformation, because the pre-established concepts were analyzed with the help of mediation, so that the group felt more autonomous and safe to read images at the end. The survey also showed significant data, so that the school could develop new methods of teaching televisual reading.

When wolves cry: long distance calling by wild maned wolves

The maned wolf (Chrysocyon brachyurus Illiger 1815) is the biggest canid in South America and it is considered a “near threatened” species by IUCN. Because of its nocturnal, territorial and solitary habits, there are still many understudied aspects of their behavior in natural environments, including acoustic communication. In its vocal repertoire, the wolf presents a longdistance call named “roar-bark” which, according to literature, functions for spacing maintenance between individuals and/or communication between members of the reproductive pair inside the territory. In this context, this study aimed: 1) to compare four methods for detecting maned wolf’s roar-barks in recordings made in a natural environment, in order to elect the most efficient one for our project; 2) to understand the night emission pattern of these vocalizations, verifying possible weather and moon phases influences in roarbark’s emission rates; and 3) to test Passive Acoustic Monitoring as a tool to identify the presence of maned wolves in a natural environment. The study area was the Serra da Canastra National Park (Minas Gerais, Brazil), where autonomous recorders were used for sound acquisition, recording all night (from 06pm to 06am) during five days in December/2013 and every day from April to July/2014. Roar-barks’ detection methods were tested and compared regarding time needed to analyze files, number of false positives and number of correctly identified calls. The mixed method (XBAT + manual) was the most efficient one, finding 100% of vocalizations in almost half of the time the manual method did, being chosen for our data analysis. By studying roarbarks’ temporal variation we verified that the wolves vocalize more in the early hours of the evening, suggesting an important social function for those calls at the beginning of its period of most intense activity. Average wind speed negatively influenced vocalization rate, which may indicate lower sound reception of recorders or a change in behavioral patterns of wolves in high speed wind conditions. A better understanding of seasonal variation of maned wolves’ vocal activity is required, but our study already shows that it is possible to detect behavioral patterns of wild animals only by sound, validating PAM as a tool in this species’ conservation.

O emprego do imalt como solução interpretativo-composicional em 3 obras autorais para violão

The task of expression undertaken by the performer falls largely on the right hand of guitarist. Aware of this fact, past and present masters have left their contributions to the development of right hand technique. It is clear, with rare exceptions, that educational and interpretative proposals, so far, have addressed the attack on the strings from the flexion of the fingers. This work, however, presents a technical resource called imalt, including in the attack action, the extension movement. Some techniques used in specific circumstances, such as the dedillo, the alzapúa, the tremulo and the rasgueado also use extension movements in the attack. They are put in perspective with the imalt providing a panoramic view of their individual characteristics. The use of imalt in the traditional guitar repertoire is exemplified in Villa Lobos, Ponce and Brouwer. Three pieces were composed for this work: Shravana, Alegoria and Vandana. Compositional techniques such as melodic contour applying and ostinato have been reviewed and used in the preparation of these compositions. A detailed record of compositional trajectory is presented. Therefore, the Model for the Compositional Process Accompaniment according Silva (2007) is used. Some events that have left the imalt in evidence are reported, as the launch and distribution of the Compact Disc (CD) Imalt, publishing scores and interviews. Finally is presented concluding comments, pointing possibilities opened up by this work.

Behavioural profiles of captive capuchin monkeys (Sapajus spp.): analyses at group and individual levels

The use of behavioural indicators of suffering and welfare in captive animals has produced ambiguous results. In comparisons between groups, those in worse condition tend to exhibit increased overall rate of Behaviours Potentially Indicative of Stress (BPIS), but when comparing within groups, individuals differ in their stress coping strategies. This dissertation presents analyses to unravel the Behavioural Profile of a sample of 26 captive capuchin monkeys, of three different species (Sapajus libidinosus, S. flavius and S. xanthosternos), kept in different enclosure types. In total, 147,17 hours of data were collected. We explored four type of analysis: Activity Budgets, Diversity indexes, Markov chains and Sequence analyses, and Social Network Analyses, resulting in nine indexes of behavioural occurrence and organization. In chapter One we explore group differences. Results support predictions of minor sex and species differences and major differences in behavioural profile due to enclosure type: i. individuals in less enriched enclosures exhibited a more diverse BPIS repertoire and a decreased probability of a sequence with six Genus Normative Behaviour; ii. number of most probable behavioural transitions including at least one BPIS was higher in less enriched enclosures; iii. proeminence indexes indicate that BPIS function as dead ends of behavioural sequences, and proeminence of three BPIS (pacing, self-direct, active I) were higher in less enriched enclosures. Overall, these data are not supportive of BPIS as a repetitive pattern, with a mantra-like calming effect. Rather, the picture that emerges is more supportive of BPIS as activities that disrupt organization of behaviours, introducing “noise” that compromises optimal activity budget. In chapter Two we explored individual differences in stress coping strategies. We classified individuals along six axes of exploratory behaviour. These were only weakly correlated indicating low correlation among behavioural indicators of syndromes. Nevertheless, the results are suggestive of two broad stress coping strategies, similar to the bold/proactive and shy/reactive pattern: more exploratory capuchin monkeys exhibited increased values of proeminence in Pacing, aberrant sexual display and Active 1 BPIS, while less active animals exhibited increased probability in significant sequences involving at least one BPIS, and increased prominence in own stereotypy. Capuchin monkeys are known for their cognitive capacities and behavioural flexibility, therefore, the search for a consistent set of behavioural indictors of welfare and individual differences requires further studies and larger data sets. With this work we aim contributing to design scientifically grounded and statistically correct protocols for collection of behavioural data that permits comparability of results and meta-analyses, from whatever theoretical perspective interpretation it may receive.

Classificação de técnicas estendidas no contrabaixo acústico

This work is to identify and classify extended techniques on acoustic bass. The main purpose of this classification is to provide the bass better understanding and practice these techniques. For this, we carried out a literature review, it was noted that, in academia, this topic is new and understanding for some musicians is still complex and nebulous. To assist in the difficulties of the bass player, the extended techniques were divided into two parts, proposing different approaches. The first part proposes the experimentation and exploration of conventional and unconventional techniques from other instruments on acoustic bass. The second seeks to identify and rank the extended techniques, showing excerpts from the solo instrument repertoire compositions. On each, there are still referenced authors and their contributions to the instrumental practice these techniques. In both categories of classification procedures were presented to be adopted by the bass player for the implementation of those techniques, as well as suggestions for their study. Among the main results, it was found that through the proposed classification of these techniques, one can incorporate new resources to technical universe and timbre of the instrument. Lastly, it was found a creation of a composition performed by interaction between composer and performer, containing new extended techniques or extended techniques not found in the instrument's contemporary soloist repertoire.

Patterns in personal experience narratives: storytelling at cod harbour - a Newfoundland fishing community

This study is concerned with storytelling as a part of the folk culture of a fishing community on the north east coast of Newfoundland. The study is based on field work done in the community throughout the summer of 1969 during which I tape recorded oral narratives along with other folklore and folklife material . The principal genre discussed is the personal experience narrative which is an account of the experiences of either the narrator, someone in his kin network, orhis friends. It was found that a large number of community residents communicate in narrative form and that the narratives function to substantiate conversation preceeding the narrativei have a didactic function; function as a means of entertainment~ and reflect the narrators' and the community's value system. The methods employed in collecting the material were the directive and the non-directive interview techniques and participant observation. Collecting was done mainly among fishermen between fifty and eighty years of age and who, on -the average, had not gone beyond the sixth grade in school. Since the narratives are so much a part of the environment, I give an account of the community culture. The principal things that I deal with are the community's history, economy, education, religion, and social life which includes rites of passage, calendar customs , social events, visiting patterns, and gossip. Information in each of these categories is based primarily on oral reports, narratives and documented materials. After a discussion of the storytelling process in the community, I deal specifically with four male narrators. For each I give biographical information, discuss his repertoire, telling situations, style, and give a sampling of his narratives. The fourth narrator is discussed in more detail than the first three. The narratives of the latter comprise the final chapter in the study, and have been analyzed to show what they tell us about the narrator's style, his value system, and the community culture.

The expression of tradition: perennial gardening in St. John's, Newfoundland

In order to understand the processes which effect the individual realization of garden design, I have studied the practise of perennial gardening in St. John's, Newfoundland. I begin with an examination of the practical constraints on design intentions resulting from difficult growing conditions, and a limited market of plant materials, relevant gardening literature and skilled· garden workers. I establish the local repertoire of design models within which individual gardens are executed. Finally, I record the "text" of six ·perennial gardens and the commentary of their principal designers in order to examine both the implicit and explicit considerations informing the structure of the gardens. A sample of gardens has been examined in order to represent two principal performance contexts -- the public garden and the private garden -- and a characteristic selection of garden style and plant material is observed. The public gardens typically recall the "traditional" use of perennials in Newfoundland gardens through the selection of "old fashioned" plant species and through the overall design of the bed. In contrast, the private gardeners have generally adopted the style of the more recently fashionable "perennial border". However, below the level of design the private gardeners continue to express a sense of tradition in the _repetition of conventions of behaviour and expression among the gardeners' families and friends, in the propagation of individual plants grown by the gardeners' parents, and in the maintenance of a family interest in gardening. This examination of the practise of gardening, thus, leads away from the folklorists' traditional focus on the continuity of the traditional "item" towards an understanding of tradition as an expression of continuity which is given tangible shape according to the avenues of shared communication within particular performance contexts.

A Formação de professores nas tramas do virtual

This study aims to reflect on the cultural and aesthetics formation of teacher, and how they act as a co-author in the virtual environment. The reflection permeates on topics such as: The Information Age and the challenges of the teacher in the twenty-first century; teacher professional development and the multiple personal identities; the importance of cultural repertoire for teaching practice and the role of the teacher as co-author in the informational network. In addition to the theoretical reflections were conducted two focus groups with the participation of teachers with different graduations and working in various levels of education to discuss the presented topics. It was proposed to create a website for the teacher to sail and collaborate with posts on many cultural artifacts. For the construction of the content for the site, it developed a “daily creation”, which is the search information storage from multiple sources, such as academic papers, songs, websites, magazines, comics, blogs, books, photographs, advertisements, finally everything that can increase imagination and serve for the production of content. Data analysis of the focus group showed that teachers recognize the varied cultural repertoire makes for a good professional aplomb, but cannot actively participate in the local culture. It was also found that the teacher has difficulty manipulating information technology and communication and therefore, distance themselves from an active production network. The focus group contributed to building a website and posts on cultural artifacts. Production can be accessed at www.digitaldoprofessor.com.

Impacto de la haploinsuficiencia de CD3 en la expresión y función del complejo TCR/CD3 en humanos y ratones

TCR/CD3 (αβTCRand γδTCR) complexes are members of a family of modular biosensors that are responsible for driving T-cell development, activation, and effector functions. They inform essential checkpoint decisions by relaying key information from their ligand-binding modules (TCR chains) to their signaling modules (CD3γε, CD3δε and CD3ζζ) and onto the intracellular signaling apparatus. Their actions shape the T-cell repertoire, as well as T-cell-mediated immunity; yet, the mechanisms that underlie their activity are still to be precisely determined. As with any molecular machine, understanding how they function depends critically on dissecting how their parts fit and work together. T-cell receptor immunodeficiencies (TCRID) are low-prevalence autosomal recessive diseases characterized by impaired surface TCR expression, frequently associated with peripheral blood T lymphocytopenia, severe combined ID (SCID) and (or) autoimmune symptoms, but not associated with B or natural killer (NK) lymphocytopenia. Several CD3, CD247, and TCR deficiencies have been described which can be classified as complete or partial according to the absence or presence of residual levels of the affected protein. Although rare and sometimes based on single cases, TCRID offer rich information about the underpinnings of human TCR structure and function, which in turn impact our understanding of T-cell development and function... NOTA 520 8 Las inmunodeficiencias humanas del receptor de antígeno de los linfocitos T (TCR) son enfermedades autosómicas recesivas con baja prevalencia, caracterizadas por un defecto de expresión del TCR asociado a una linfopenia T selectiva. La ausencia congénita de componentes del TCR tiene un impacto diferencial en el desarrollo y función de los linfocitos T, que depende de la cadena del TCR afectada y de la especie, siendo en algunos casos diferente en los pacientes humanos en comparación con los modelos en ratones. Las inmunodeficiencias del TCR han sido ampliamente estudiadas, en particular las de las sub-unidades CD3 del complejo receptor. En contraste, hasta ahora es muy poca la atención que se le ha prestado a los potenciales efectos de la haploinsuficiencia de componentes del TCR en el desarrollo, fenotipo y función de los linfocitos T. Esto es debido en gran parte al hecho de que los individuos haploinsuficientes (portadores de mutaciones nulas en heterocigosis) no presentan alteraciones obvias de la inmunidad mediada por células T o signos de enfermedad. En este trabajo se analiza por primera vez, en humanos y modelos de ratones, el impacto de la haploinsuficiencia de CD3 y CD3 en la expresión y funcionalidad del TCR, y su potencial relevancia en el desarrollo y función de los linfocitos T. Los resultados indican que la haploinsuficiencia de CD3 y, en menor medida, la de CD3causa una disminución en la expresión del TCR en la superficie de las células T y T, y provoca alteraciones claras en el desarrollo y función de los linfocitos T en ambas especies...

The sound of whiteness: early music vocal performance practice in Britain

American Musicological Society annual meeting, San Francisco, 10 Nov. 2011

A long non-coding RNA targets microRNA miR-34a to regulate colon cancer stem cell asymmetric division.

The roles of long non-coding RNAs (lncRNAs) in regulating cancer and stem cells are being increasingly appreciated. Its diverse mechanisms provide the regulatory network with a bigger repertoire to increase complexity. Here we report a novel LncRNA, Lnc34a, that is enriched in colon cancer stem cells (CCSCs) and initiates asymmetric division by directly targeting the microRNA miR-34a to cause its spatial imbalance. Lnc34a recruits Dnmt3a via PHB2 and HDAC1 to methylate and deacetylate the miR-34a promoter simultaneously, hence epigenetically silencing miR-34a expression independent of its upstream regulator, p53. Lnc34a levels affect CCSC self-renewal and colorectal cancer (CRC) growth in xenograft models. Lnc34a is upregulated in late-stage CRCs, contributing to epigenetic miR-34a silencing and CRC proliferation. The fact that lncRNA targets microRNA highlights the regulatory complexity of non-coding RNAs (ncRNAs), which occupy the bulk of the genome.
