A demanda por deuses: religião, globalização e culturas locais

Nesta tese serão discutidas as principais interseções entre a expansão do pentecostalismo protestante e as culturas locais que são alvo de sua ação evangelizadora. Mais especificamente, pretendemos demonstrar, a partir de estudos realizados em algumas regiões do estado de Minas Gerais e Norte de Portugal, de que forma certas conformações culturais mostram-se extremamente refratárias à implantação e limitam o crescimento das igrejas pentecostais. Nesse sentido, procuramos relativizar algumas vertentes teóricas que têm sido chamadas de paradigma da escolha racional em religião, que em um salto para fora da teoria sociológica de entendimento da religião busca na Economia seus principais fundamentos. De forma diversa, nesta tese defender-se-á que processos histórico-estruturais influenciam a demanda por religião e que a produção e principalmente o consumo dos bens religiosos estão imersos nas relações sociais face-a-face. Desta maneira, não acreditamos serem as regulações estatais a principal variável quando se trata de diversidade religiosa. Outros sim, pensamos que este papel cabe às relações societais, que limitam e regulam o trânsito dos indivíduos entre as denominações religiosas.

Mathematical models for the prediction of temperature distributions resulting from the discharge of heated water into large bodies of water

Mathematical models for heated water outfalls were developed for three flow regions. Near the source, the subsurface discharge into a stratified ambient water issuing from a row of buoyant jets was solved with the jet interference included in the analysis. The analysis of the flow zone close to and at intermediate distances from a surface buoyant jet was developed for the two-dimensional and axisymmetric cases. Far away from the source, a passive dispersion model was solved for a two dimensional situation taking into consideration the effects of shear current and vertical changes in diffusivity. A significant result from the surface buoyant jet analysis is the ability to predict the onset and location of an internal hydraulic jump. Prediction can be made simply from the knowledge of the source Froude number and a dimensionless surface exchange coefficient. Parametric computer programs of the above models are also developed as a part of this study. This report was submitted in fulfillment of Contract No. 14-12-570 under the sponsorship of the Federal Water Quality Administration.

Regional variation in the annual feeding cycle of juvenile walleye pollock (Theragra chalcogramma) in the western Gulf of Alaska

Juvenile fish in temperate coastal oceans exhibit an annual cycle of feeding, and within this cycle, poor wintertime feeding can reduce body growth, condition, and perhaps survival, especially in food-poor areas. We examined the stomach contents of juvenile walleye pollock (Theragra chalcogramma) to explain previously observed seasonal and regional variation in juvenile body condition. Juvenile walleye pollock (1732 fish, 37–250 mm standard length) of the 2000 year class were collected from three regions in the Gulf of Alaska (Kodiak, Semidi, and Shumagin) representing an area of the continental shelf of ca. 100,000 km2 during four seasons (August 2000 to September 2001). Mean stomach content weight (SCW, 0.72% somatic body weight) decreased with fish body length except from winter to summer 2001. Euphausiids composed 61% of SCW and were the main determinant of seasonal change in the diets of fish in the Kodiak and Semidi regions. Before and during winter, SCW and the euphausiid dietary component were highest in the Kodiak region. Bioenergetics modeling indicated a relatively high growth rate for Kodiak juveniles during winter (0.33 mm standard length/d). After winter, Shumagin juveniles had relatively high SCW and, unlike the Kodiak and Semidi juveniles, exhibited no reduction in the euphausiid dietary component. These patterns explain previous seasonal and regional differences in body condition. We hypothesize that high-quality feeding locations (and perhaps nursery areas) shift seasonally in response to the availability of euphausiid

Analysis of the Response Speed of Musculature of the Knee in Professional Male and Female Volleyball Players

The aim of this study was to evaluate the normalized response speed (Vrn) of the knee musculature (flexor and extensor) in high competitive level volleyball players using tensiomyography (TMG) and to analyze the muscular response of the vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL), and biceps femoris (BF) in accordance with the specific position they play in their teams. One hundred and sixty-six players (83 women and 83 men) were evaluated. They belonged to eight teams in the Spanish women's superleague and eight in the Spanish men's superleague. The use of Vrn allows avoiding possible sample imbalances due to anatomical and functional differences and demands. We found differences between Vrn in each of the muscles responsible for extension (VM, RF, and VL) and flexion (BF) regardless of the sex. Normalized response speed differences seem to be larger in setters, liberos and outside players compared to middle blockers and larger in males when compared to females. These results of Vrn might respond to the differences in the physical and technical demands of each specific position, showing an improved balance response of the knee extensor and flexor musculature in male professional volleyball players.

Perfil motivacional de las mujeres participantes en la prueba atlética de los 3000 metros obstáculos

[ES] Los 3000 metros obstáculos es una especialidad del atletismo ubicada dentro de las pruebas de medio fondo, que comprende la carrera plana y el paso de los obstáculos, incluyendo un foso agua llamado ría. Es la especialidad de atletismo con menos participantes en carrera ya sea en género femenino como en masculino, pero ¿A qué se debe esta baja participación? Tanto la alta exigencia técnica en carrera como los pasos de los obstáculos son una de las razones, ya que, el paso de la ría requiere una refinada técnica y dificultad adquirida. Este estudio analizará a distintas atletas, con el fin de crear el perfil motivacional de las atletas que compiten en esta prueba, encontrar las razones por las que se decantan por otras especialidades del atletismo y no por esta, y con ello averiguar las razones de la baja participación en esta modalidad.

Desigualdades sociais nas concepções dos professores e estudantes do PROEJA no Instituto Federal de Educação, Ciência e Tecnologia do Sertão Pernambucano - Campus Petrolina-PE

Este trabalho apresenta resultados de uma pesquisa realizada no IFSERTÃO - Instituto Federal de Educação, Ciência e Tecnologia do Sertão Pernambucano a respeito das desigualdades sociais nas concepções dos professores e estudantes do PROEJA. Teve como objetivo analisar e compreender os sentidos produzidos pelos sujeitos da pesquisa sobre as desigualdades sociais e suas perspectivas de superação, considerando seu histórico e seus aspectos atuais. Foi organizado epistemologicamente numa abordagem de pesquisa qualitativa a partir do ponto de vista metodológico do estudo de caso do tipo descritivo e analítico com entrevistas e análise do documento Base do Programa institucionalizado pelo MEC, buscando identificar as aproximações ou distanciamentos entre as concepções dos entrevistados com a proposta do material institucional no que diz respeito às perspectivas de superação das desigualdades no contexto da EJA. O problema da pesquisa foi formulado mediante o seguinte questionamento: Como as desigualdades sociais se apresentam nas concepções dos professores e estudantes do programa e quais suas perspectivas de superação? Para estudo do problema, procedeu-se à imersão no campo empírico da pesquisa com abordagens e utilização de um roteiro de entrevistas previamente formulado, incluiu-se a leitura flutuante do material coletado e as vozes dos entrevistados foram gravadas, transcritas, lidas e analisadas, buscando a captação do sentido atribuído pelos sujeitos a respeito das desigualdades sociais. Mediante essa trajetória, identificou-se, nas concepções dos sujeitos da pesquisa, que o trabalho se apresenta como centralidade no que se refere às manifestações das desigualdades sociais no contexto da EJA/PROEJA, bem como suas diferentes feições na lógica do sistema capitalista no que se refere a educar para a empregabilidade atendendo às exigências do capital. Assim, considerando que, historicamente, a EJA é uma modalidade de ensino que vem sendo ofertada para sujeitos que tiveram seus percursos escolares interrompidos pela condição de trabalhadores, esse tema se configura como estudo de grande relevância no contexto das políticas de Educação de Jovens e Adultos trabalhadores.

Catches in ghost-fishing octopus and fish traps in the northeastern Atlantic Ocean (Algarve, Portugal)

Ghost fishing is the term used to describe the continued capture of fish and other living organisms after a fisherman has lost all control over the gear. Traps may be lost for a variety of reasons including theft, vandalism, abandonment, interactions with other gear, fouling on the bottom (i.e., traps and ropes are caught on rocky substrate), bad weather, and human error (Laist, 1995). Annual trap loss can be as high as 20% to 50% of fished traps in some fisheries (Al-Masroori et al., 2004). Because lost traps can continue to fish for long periods, albeit with decreasing efficiency over time (e.g., Smolowitz, 1978; Breen, 1987, 1990; Guillory, 1993), ghost fishing is a concern in fisheries worldwide.

Effects of Small-Sided Games vs. Interval Training in Aerobic Fitness and Physical Enjoyment in Young Elite Soccer Players

The purpose of this study was to compare the effects of Small-Sided Games (SSG) vs. Interval Training (IT) in soccer training on aerobic fitness and physical enjoyment in youth elite soccer players during the last 8 weeks of the season. Seventeen U-16 male soccer players (age = 15.5 +/- 0.6 years, and 8.5 years of experience) of a Spanish First Division club academy were randomized to 2 different groups for 6 weeks: SSG group (n = 9) and IT group (n = 8). In addition to the usual technical and tactical sessions and competitive games, the SSG group performed 11 sessions with different SSGs, whereas the IT group performed the same number of sessions of IT. Players were tested before and after the 6-week training intervention with a continuous maximal multistage running field test and the counter movement jump test (CMJ). At the end of the study, players answered the physical activity enjoyment scale (PACES). During the study, heart rate (HR) and session perceived effort (sRPE) were assessed. SSGs were as effective as IT in maintaining the aerobic fitness in elite young soccer players during the last weeks of the season. Players in the SSG group declared a greater physical enjoyment than IT (P = 0.006; ES = 1.86 +/- 1.07). Coaches could use SSG training during the last weeks of the season as an option without fear of losing aerobic fitness while promoting high physical enjoyment.

Evaluation of a Pound Net Leader Designed to Reduce Sea Turtle Bycatch

Offshore pound net leaders in the southern portion of Chesapeake Bay in Virginia waters were documented to incidentally take protected loggerhead, Caretta caretta, and Kemp’s ridley, Lepidochelys kempii, sea turtles. Because of these losses, NOAA’s National Marine Fisheries Service (NMFS) in 2004 closed the area to offshore pound net leaders annually from 6 May to 15 July and initiated a study of an experimental leader design that replaced the top two-thirds of the traditional mesh panel leader with vertical ropes (0.95 cm) spaced 61 cm apart. This experimental leader was tested on four pound net sites on the eastern shore of Chesapeake Bay in 2004 and 2005. During the 2 trial periods, 21 loggerhead and Kemp’s ridley sea turtles were found interacting with the control leader and 1 leatherback turtle, Dermochelys coriacea, was found interacting with the experimental leader. Results of a negative binomial regression analysis comparing the two leader designs found the experimental leader significantly reduced sea turtle interactions (p=0.03). Finfish were sampled from the pound nets in the study to assess finfish catch performance differences between the two leader designs. Although the conclusions from this element of the experiment are not robust, paired t-test and Wilcoxon signed rank test results determined no significant harvest weight difference between the two leaders. Kolmogorov-Smirnov tests did not reveal any substantive size selectivity differences between the two leaders.

A discrete dislocation analysis of fatigue crack growth

Cyclic loading of a plane strain mode I crack under small scale yielding is analyzed using discrete dislocation dynamics. The dislocations are all of edge character, and are modeled as line singularities in an elastic solid. At each stage of loading, superposition is used to represent the solution in terms of solutions for edge dislocations in a half-space and a non-singular complementary solution that enforces the boundary conditions, which is obtained from a linear elastic, finite element solution. The lattice resistance to dislocation motion, dislocation nucleation, dislocation interaction with obstacles and dislocation annihilation are incorporated into the formulation through a set of constitutive rules. An irreversible relation between the opening traction and the displacement jump across a cohesive surface ahead of the initial crack tip is also specified, which permits crack growth to emerge naturally. It is found that crack growth can occur under cyclic loading conditions even when the peak stress intensity factor is smaller than the stress intensity required for crack growth under monotonic loading conditions; however below a certain threshold value of ΔKI no crack growth was seen.

Test on prestressed concrete beam with AFRP spiral confinement and external aramid tendons

This paper describes an experimental study of a new form of prestressed concrete beam. Aramid Fiber Reinforced Polymers (AFRPs) are used to provide compression confinement in the form of interlocking circular spirals, while external tendons are made from parallel-lay aramid ropes. The response shows that the confinement of the compression flange significantly increases the ductility of the beam, allowing much better utilization of the fiber strength. The failure of the beam is characterized by rupture of spiral confinement reinforcement.

Bayesian inference for multidimensional NMR image reconstruction

Reconstruction of an image from a set of projections has been adapted to generate multidimensional nuclear magnetic resonance (NMR) spectra, which have discrete features that are relatively sparsely distributed in space. For this reason, a reliable reconstruction can be made from a small number of projections. This new concept is called Projection Reconstruction NMR (PR-NMR). In this paper, multidimensional NMR spectra are reconstructed by Reversible Jump Markov Chain Monte Carlo (RJMCMC). This statistical method generates samples under the assumption that each peak consists of a small number of parameters: position of peak centres, peak amplitude, and peak width. In order to find the number of peaks and shape, RJMCMC has several moves: birth, death, merge, split, and invariant updating. The reconstruction schemes are tested on a set of six projections derived from the three-dimensional 700 MHz HNCO spectrum of a protein HasA.
