A HISTÓRIA DE UM SILÊNCIO: UM ESTUDO DE CASO SOBRE QUESTÕES DA NEGRITUDE EM UMA COMUNIDADE BATISTA DA PERIFERIA DA CIDADE DE SÃO PAULO

O objetivo deste trabalho foi analisar práticas microbianas , singulares e plurais, relativas ao tema da negritude, no cotidiano da comunidade batista Maranata, como estudo de caso de um grupo religioso no distrito Grajaú, periferia da cidade de São Paulo. Fazendo uso da História Oral, produzimos nossas fontes de analise documental dando voz a um grupo de pessoas dessa comunidade evangélica, que se auto declararam pretas e pardas. Detectamos em seu discurso a percepção que têm em relação à temática da negritude brasileira, sobre as políticas de ações afirmativas, sobre a presença do preconceito e discriminação racial na atual sociedade, bem como a posição da comunidade diante dessa temática. A pergunta pelo papel da mentalidade religiosa no enfrentamento desta problemática foi o foco orientador destes diferentes eixos de observação. Por ser um tema muito delicado e pouco discutido entre os evangélicos, percebemos que a comunidade não se sentiu muito à vontade para discuti-lo. O discurso de nossos interlocutores, que aparentemente se mostrava ambíguo e por vezes incoerente, pois ora admitia-se o preconceito racial, e ora ele era negado, foi uma forma encontrada por estes consumidores para encobrir os mecanismos de descriminação e exclusão que também percebem existir dentro de sua comunidade de fé e para, desse modo, sentirem-se aceitos na comunidade, criando assim táticas de sobrevivência e espaços de pertencimento em meio às estratégias impostas pela denominação religiosa.(AU)

PODER E EXPERIÊNCIA RELIGIOSA: UMA HISTÓRIA DE UM CISMA PENTECOSTAL NA CONVENÇÃO BATISTA BRASILEIRA NA DÉCADA DE 1960

A presente dissertação é resultado de uma pesquisa acerca de um cisma pentecostal na Convenção Batista Brasileira, na década de 1960. No foco do conflito encontra-se um Movimento de Renovação Espiritual, que defendia uma experiência de êxtase religioso, designada de batismo com o Espírito Santo, como confirmação da relação do crente com Deus. A progressiva adesão de comunidades batistas a tal proposta transformou-a numa rede alternativa de poder que causou instabilidade nas relações de poder no interior da denominação batista no Brasil. A pesquisa reconstrói os embates decisivos deste episódio e ofereceu uma interpretação a partir das teorias de Michel Foucault e Michel de Certeau, na medida em que tenta decifrar os mecanismos institucionais de controle em confronto com as táticas das redes de poder. No contexto histórico brasileiro de efervescência não só religiosa, os mecanismos de vigilância da Convenção Batista Brasileira mostraram-se insuficientes para a manutenção da unidade ameaçada, uma vez que puniu os grupos opositores com a exclusão.(AU)

Host–parasite relatedness shown by protein fingerprinting in a brood parasitic bird

Brood parasitism as an alternative female breeding tactic is particularly common in ducks, where hosts often receive eggs laid by parasitic females of the same species and raise their offspring. Herein, we test several aspects of a kin selection explanation for this phenomenon in goldeneye ducks (Bucephala clangula) by using techniques of egg albumen sampling and statistical bandsharing analysis based on resampling. We find that host and primary parasite are indeed often related, with mean r = 0.13, about as high as between first cousins. Relatedness to the host is higher in nests where a parasite lays several eggs than in those where she lays only one. Returning young females parasitize their birth nestmates (social mothers or sisters, which are usually also their genetic mothers and sisters) more often than expected by chance. Such adult relatives are also observed together in the field more often than expected and for longer periods than other females. Relatedness and kin discrimination, which can be achieved by recognition of birth nestmates, therefore play a role in these tactics and probably influence their success.

Loss of speciation rate will impoverish future diversity

Human activities have greatly reduced the amount of the earth's area available to wild species. As the area they have left declines, so will their rates of speciation. This loss of speciation will occur for two reasons: species with larger geographical ranges speciate faster; and loss of area drives up extinction rates, thus reducing the number of species available for speciation. Theory predicts steady states in species diversity, and fossils suggest that these have typified life for most of the past 500 million years. Modern and fossil evidence indicates that, at the scale of the whole earth and its major biogeographical provinces, those steady states respond linearly, or nearly so, to available area. Hence, a loss of x% of area will produce a loss of about x% of species. Local samples of habitats merely echo the diversity available in the whole province of which they are a part. So, conservation tactics that rely on remnant patches to preserve diversity cannot succeed for long. Instead, diversity will decay to a depauperate steady state in two phases. The first will involve deterministic extinctions, reflecting the loss of all areas in which a species can ordinarily sustain its demographics. The second will be stochastic, reflecting accidents brought on by global warming, new diseases, and commingling the species of the separate bio-provinces. A new kind of conservation effort, reconciliation ecology, can avoid this decay. Reconciliation ecology discovers how to modify and diversify anthropogenic habitats so that they harbor a wide variety of species. It develops management techniques that allow humans to share their geographical range with wild species.

A total system approach to sustainable pest management

A fundamental shift to a total system approach for crop protection is urgently needed to resolve escalating economic and environmental consequences of combating agricultural pests. Pest management strategies have long been dominated by quests for “silver bullet” products to control pest outbreaks. However, managing undesired variables in ecosystems is similar to that for other systems, including the human body and social orders. Experience in these fields substantiates the fact that therapeutic interventions into any system are effective only for short term relief because these externalities are soon “neutralized” by countermoves within the system. Long term resolutions can be achieved only by restructuring and managing these systems in ways that maximize the array of “built-in” preventive strengths, with therapeutic tactics serving strictly as backups to these natural regulators. To date, we have failed to incorporate this basic principle into the mainstream of pest management science and continue to regress into a foot race with nature. In this report, we establish why a total system approach is essential as the guiding premise of pest management and provide arguments as to how earlier attempts for change and current mainstream initiatives generally fail to follow this principle. We then draw on emerging knowledge about multitrophic level interactions and other specific findings about management of ecosystems to propose a pivotal redirection of pest management strategies that would honor this principle and, thus, be sustainable. Finally, we discuss the potential immense benefits of such a central shift in pest management philosophy.

Estudo das táticas reprodutivas em duas espécies de Coenagrionidae (Odonata: Zygoptera)

Nos estudos sobre a teoria da Seleção Sexual, as libélulas têm sido amplamente estudadas devido à grande variedade de padrões comportamentais, de coloração e táticas reprodutivas. Como forma de demonstrar táticas reprodutivas adotadas por duas espécies de libélulas, esta dissertação teve como objetivos principais: i) investigar o papel de traços secundários como a coloração corporal na competição intra-sexual de uma espécie territorial e ii) analisar se os traços corporais como tamanho e morfologia das asas predizem a tática de acasalamento adotada por machos de uma espécie nãoterritorial. Sugere-se que a coloração corporal pode predizer o resultado de lutas e também se correlacionar positivamente com a condição física dos machos territoriais de Tigriagrion aurantinigrum. Ademais, traços corporais como o tamanho e a morfologia das asas influenciam na tática reprodutiva utilizada por machos não-territoriais de Epipleoneura williamsoni. Portanto, com os resultados obtidos, conclui-se que a variação nos sinais visuais exerce um papel essencial na comunicação animal e na resolução de conflitos, indicando ainda que pode haver uma sinalização da condição física dos machos. Além disso, os resultados mostraram evidências em como diferentes táticas reprodutivas se relacionam com traços corporais como agilidade e tamanho corporal, os quais podem influenciar no sucesso reprodutivo dos indivíduos.

Genetic diversity and susceptibility to Vip3Aa20 protein in Brazilian populations of Helicoverpa armigera and Helicoverpa zea (Lepidoptera: Noctuidae)

Helicoverpa armigera (Hübner) was officially reported in Brazil in 2013. This species is closely related to Helicoverpa zea (Boddie) and has caused significant crop damage in Brazil. The use of genetically modified crops expressing insecticidal protein from Bacillus thuringiensis (Berliner) has been one of the control tactics for managing these pests. Genetically modified maize expressing Vip3Aa20 was approved to commercial use in Brazil in 2009. Understanding the genetic diversity and the susceptibility to B. thuringiensis proteins in H. armigera and H. zea populations in Brazil are crucial for establishing Insect Resistance Management (IRM) programs in Brazil. Therefore, the objectives of this study were: (a) to infer demographic parameters and genetic structure of H. armigera and H. zea Brazil; (b) to assess the intra and interspecific gene flow and genetic diversity of H. armigera and H. zea; and (c) to evaluate the susceptibility to Vip3Aa20 protein in H. armigera and H. zea populations of Brazil. A phylogeographic analysis of field H. armigera and H. zea populations was performed using a partial sequence data from the cytochrome c oxidase I (COI) gene. H. armigera individuals were most prevalent on dicotyledonous hosts and H. zea individuals were most prevalent on maize crops. Both species showed signs of demographic expansion and no genetic structure. High genetic diversity and wide distribution were observed for H. armigera. A joint analysis indicated the presence of Chinese, Indian, and European lineages within the Brazilian populations of H. armigera. In the cross-species amplification study, seven microsatellite loci were amplified; and showed a potential hybrid offspring in natural conditions. Interespecific analyses using the same microsatellite loci with Brazilian H. armigera and H. zea in compare to the USA H. zea were also conducted. When analyses were performed within each species, 10 microsatellites were used for H. armigera, and eight for H. zea. We detected high intraspecific gene flow in populations of H. armigera and H. zea from Brazil and H. zea from the USA. Genetic diversity was similar for both species. However, H. armigera was more similar to H. zea from Brazil than H. zea from the USA and some putative hybrid individuals were found in Brazilian populations.Tthere was low gene flow between Brazilian and USA H. zea. The baseline susceptibility to Vip3Aa20 resulted in low interpopulation variation for H. zea (3-fold) and for H. armigera (5-fold), based on LC50. H. armigera was more tolerant to Vip3Aa20 than H. zea (≈ 40 to 75-fold, based on CL50). The diagnostic concentration for susceptibility monitoring, based on CL99, was fairly high (6,400 ng Vip3Aa20/cm2) for H. zea and not validated for H. armigera due to the high amount of protein needed for bioassays. Implementing IRM strategies to Vip3Aa20 in H. armigera and H. zea will be of a great challenge in Brazil, mainly due to the low susceptibility to Vip3Aa20 and high genetic diversity and gene flow in both species, besides a potential of hybrid individuals between H. armigera and H. zea under field conditions.

A Fair Day's Wages: Liberty, Legality, and Liability Among Denver's Day Laborers

Day laborers occupy an essential position in Denver’s booming construction industry. Day laborers make up a highly flexible, highly effective workforce able to respond to market changes. For day laborers, informal day-labor gathering points provide increased control over working hours and employee-employer relationships when compared to traditional wage labor. Still, recent legislation and policies around irregular migration has forced large numbers of workers who may have benefited from the stability of full-time regular employment into the informal sector. The day laborers’ flexibility also exposes them to employers constantly inventing ways to deny them the wages and benefits they are owed. Despite changes in Colorado law in attempts to strengthen workers’ recourse against their employers, and despite social and individual tactics day laborers employ to mitigate their vulnerability, systematic structural, symbolic, and everyday violence continue to advantage employers.

Sangre fresca publicitaria: True Blood y las transfusiones de la ficción

El artículo analiza el concepto de transmedia storytelling en su dimensión publicitaria. En cierto modo, las narrativas transmediáticas, esto es, la diseminación de las tramas ficcionales a lo largo de soportes y plataformas diversos pero sinérgicos (letra impresa, cine, televisión) fueron empleadas en primer lugar en el mensaje publicitario, obligado a transmigrar por su carencia de un soporte exclusivo y a cambio por la vocación de colonizarlos a todos. Hoy día es el producto cultural ficcional el que devuelve a la publicidad el préstamo: son los universos ficcionales los marcos más propiciatorios para el consumo, no sólo de la cultura industrial en sí, en cualquiera de sus soportes, sino de todo un rosario de marcas arracimadas en torno a la narrativa ficcional. Analizaremos en detalle este fenómeno en una teleserie norteamericana muy reciente, True Blood (HBO, 2008), todavía en emisión, y en todo el universo ficcional que orbita a su alrededor. La diferencia entre los productos culturales en sí y las piezas publicitarias encargadas de promocionarlos –como ya vio premonitoriamente Adorno- se disuelve en un continuo cross-promotional, que tiende a enmascarar también los límites entre las estrategias corporativas y las intervenciones del fan.

Profiling in sport using momentum and perturbations

Examining a team’s performance from a physical point of view their momentum might indicate unexpected turning points in defeat or success. Physicists describe this value as to require some effort to be started, but also that it is relatively easy to keep it going once a sufficient level is reached (Reed and Hughes, 2006). Unlike football, rugby, handball and many more sports, a regular volleyball match is not limited by time but by points that need to be gathered. Every minute more than one point is won by either one team or the other. That means a series of successive points enlarges the gap between the teams making it more and more difficult to catch up with the leading one. This concept of gathering momentum, or the reverse in a performance, can give the coaches, athletes and sports scientists further insights into winning and losing performances. Momentum investigations also contain dependencies between performances or questions if future performances are reliant upon past streaks. Squash and volleyball share the characteristic of being played up to a certain amount of points. Squash was examined according to the momentum of players by Hughes et al. (2006). The initial aim was to expand normative profiles of elite squash players using momentum graphs of winners and errors to explore ‘turning points’ in a performance. Dynamic systems theory has enabled the definition of perturbations in sports exhibiting rhythms (Hughes et al., 2000; McGarry et al., 2002; Murray et al., 2008), and how players and teams cause these disruptions of rhythm can inform on the way they play, these techniques also contribute to profiling methods. Together with the analysis of one’s own performance it is essential to have an understanding of your oppositions’ tactical strengths and weaknesses. By modelling the oppositions’ performance it is possible to predict certain outcomes and patterns, and therefore intervene or change tactics before the critical incident occurs. The modelling of competitive sport is an informative analytic technique as it directs the attention of the modeller to the critical aspects of data that delineate successful performance (McGarry & Franks, 1996). Using tactical performance profiles to pull out and visualise these critical aspects of performance, players can build justified and sophisticated tactical plans. The area is discussed and reviewed, critically appraising the research completed in this element of Performance Analysis.

An experimental study on Aerobic Gymnastic: performance analysis as an effective evaluation for technique and teaching of motor gestures

Aerobic Gymnastic is the ability to perform complex movements produced by the traditional aerobic exercises, in a continuous manner, with high intensity, perfectly integrated with soundtracks. This sport is performed in an aerobic/anaerobic lactacid condition and expects the execution of complex movements produced by the traditional aerobic exercises integrated with difficulty elements performed with a high technical level. An inaccuracy about this sport is related to the name itself “aerobic” because Aerobic Gymnastic does not use just the aerobic work during the competition, due to the fact that the exercises last among 1’30” and 1’45” at high rhythm. Agonistic Aerobics exploit the basic movements of amateur Aerobics and its coordination schemes, even though the agonistic Aerobics is so much intense than the amateur Aerobics to need a completely different mix of energetic mechanisms. Due to the complexity and the speed with which you perform the technical elements of Aerobic Gymnastic, the introduction of video analysis is essential for a qualitative and quantitative evaluation of athletes’ performance during the training. The performance analysis can allow the accurate analysis and explanation of the evolution and dynamics of a historical phenomenon and motor sports. The notational analysis is used by technicians to have an objective analysis of performance. Tactics, technique and individual movements can be analyzed to help coaches and athletes to re-evaluate their performance and gain advantage during the competition. The purpose of the following experimental work will be a starting point for analyzing the performance of the athletes in an objective way, not only during competitions, but especially during the phases of training. It is, therefore, advisable to introduce the video analysis and notational analysis for more quantitative and qualitative examination of technical movements. The goal is to lead to an improvement of the technique of the athlete and the teaching of the coach.

La frontera marítima fortificada: de la vigilancia a la señalización (XVI-XIX)

During the 16th century an ambitious political programme for building towers and forts bordering the Spanish Empire’s littoral, to protect it, is materialised. This sighting network over the sea horizon had the essential mission of detecting the presence of vessels that supposed a threat. The network was organised through the strategic arrangement of watchtowers taking profit of the geographical features in the topography so that they could communicate among them with a system of visual signs. The virtual union of the stated settlements defined the fortified maritime borderline. At the same time, this network of sentinels was reinforced (in certain settlements) by the construction of fortifications that acted like centres of data reception and supplied the necessary personnel for detection and transmission. So, this mesh was established by observation points (watchtowers) and information and defense centres (fortifications) to make the news arrive to the decision centres. The present communication aims to demonstrate this military strategy providing the inventory of all defensive architectures that marked this limit between the Segura river mouth until the Huertas cape and that these are spotted from the ‘Flat’ island (later Nueva Tabarca). A riverside geography of approxi-mately 30 km long where 3 fortifications and 7 towers of diverse typologies successively took place. Among the most relevant documents of this research, we could mention the plans of the fortifycations in Guardamar and Santa Pola from the 16th century (drawn in the 18th). For this research, drawings of towers made by the Ministry of Public Works at the end of the 19th century are also important; these documents show the new military tactics, neither for attack neither for defense. At most, they replaced for maritime lighthouses for signage and help for navigation while the others towers were abandoned.

Tiburzio Spannocchi’s project for the fortifications of Fuenterrabía in 1580

Fuenterrabía (Hondarribia) is a town located on the Franco-Spanish border. Between the 16th and 19th centuries it was considered to be one of the most outstanding strongholds in the Basque Country due to its strategic position. The bastion system of fortification was extremely prevalent in this stronghold. It was one of the first Spanish towns to adopt the incipient Renaissance designs of the bastion. The military engineers subsequently carried out continuous fortification projects that enabled the structure to withstand the advances being made in artillery and siege tactics. After the construction of the citadel of Pamplona had begun in 1571, following the design of the prestigious military engineer, Jacobo Palear Fratín and being revised by Viceroy Vespasiano Gonzaga, the aforementioned engineer undertook an ambitious project commissioned by Felipe II to modernise the fortifications of Fuenterrabía. Neither the plans nor the report of this project have been conserved, but in the year 2000, César Fernández Antuña published the report written by Spannocchi on the state of the fortifications of Fuenterrabía when he arrived to the Spanish peninsula, discovered in the Archivo Histórico Provincial de Zaragoza. This document conducts an in-depth analysis of Spannocchi’s project and how it was related to Fratín’s previous project. It concludes that this project encountered problems in updating the new bastions at the end of the 16th century, and identifies the factors which prevented the stronghold from being extended as was the case in Pamplona after Fratín’s project.
