Em busca do convívio social: o regime semi-aberto no Instituto Penal Oscar Stevenson

O presente trabalho tem como objetivo central analisar o Sistema Penitenciário do Estado do Rio de Janeiro a partir do regime semi-aberto, tendo como campo de análise o Instituto Penal Oscar Stevenson, situado em Benfica, no município do Rio de Janeiro, voltado para um público carcerário feminino. Buscou-se verificar, sob o enfoque das presas, a expectativa e possibilidades de retorno ao convívio social; analisar os aspectos jurídico-institucionais referentes ao regime semi-aberto, no que tange a obtenção dos benefícios, junto a Lei de Execução Penal e identificar quais as parcerias que viabilizam a inserção delas no mercado de trabalho. Para a efetivação desse trabalho utilizou-se, preferencialmente os pressupostos teóricos e metodológicos da pesquisa quali-quantitativa, pois foi trabalhado não só no nível da objetividade, mas também no significado das ações e relações humanas, sabendo que a realidade prisional é perpassada por questões de cunho opressor, punitivo, em função de preconizar a segurança. Foram realizados também levantamentos de dados bibliográficos e censitários, bem como entrevistas semi-estruturadas junto aos agentes penitenciários do setor de educação e classificação e principalmente as presas. A análise do material coletado permitiu confirmar as hipóteses da pesquisa: i) que a ausência de oportunidades que garantam às presas os benefícios do regime semi-aberto não se dá por falta de instrumentos legais, mas sim pela burocracia no cadastramento e poucas parcerias de cursos profissionalizantes, empresas privadas que absorvam mão-de-obra das presas do regime semi-aberto; e ii) e que no momento em que as presas ainda estavam no regime fechado, não tiveram oportunidades de se capacitarem e também os vínculos familiares não foram mantidos, com isso dificultando que estas usufruam dos benefícios do regime semi-aberto. E, conseqüentemente, sendo cada vez mais adiado o seu retorno gradativo ao convívio social, através da progressão de regime.

Testable models of aquatic systems: A NERC special topic for integrating experiments and modelling

A major part of the support for fundamental research on aquatic ecosystems continues to be provided by the Natural Environment Research Council (NERC). Funds are released for ”thematic” studies in a selected special topic or programme. ”Testable Models of Aquatic Ecosystems” was a Special Topic of the NERC, initiated in 1995, the aim of which was to promote ecological modelling by making new links between experimental aquatic biologists and state-of-the-art modellers. The Topic covered both marine and freshwater systems. This paper summarises projects on aspects of the responses of individual organisms to the effects of environmental variability, on the assembly, permanence and resilience of communities, and on aspects of spatial models. The authors conclude that the NERC Special Topic has been highly successful in promoting the development and application of models, most particularly through the interplay between experimental ecologists and formal modellers.

Characterization and modeling of premixed turbulent n-heptane flames in the thin reaction zone regime

n-heptane/air premixed turbulent flames in the high-Karlovitz portion of the thin reaction zone regime are characterized and modeled in this thesis using Direct Numerical Simulations (DNS) with detailed chemistry. In order to perform these simulations, a time-integration scheme that can efficiently handle the stiffness of the equations solved is developed first. A first simulation with unity Lewis number is considered in order to assess the effect of turbulence on the flame in the absence of differential diffusion. A second simulation with non-unity Lewis numbers is considered to study how turbulence affects differential diffusion. In the absence of differential diffusion, minimal departure from the 1D unstretched flame structure (species vs. temperature profiles) is observed. In the non-unity Lewis number case, the flame structure lies between that of 1D unstretched flames with "laminar" non-unity Lewis numbers and unity Lewis number. This is attributed to effective Lewis numbers resulting from intense turbulent mixing and a first model is proposed. The reaction zone is shown to be thin for both flames, yet large chemical source term fluctuations are observed. The fuel consumption rate is found to be only weakly correlated with stretch, although local extinctions in the non-unity Lewis number case are well correlated with high curvature. These results explain the apparent turbulent flame speeds. Other variables that better correlate with this fuel burning rate are identified through a coordinate transformation. It is shown that the unity Lewis number turbulent flames can be accurately described by a set of 1D (in progress variable space) flamelet equations parameterized by the dissipation rate of the progress variable. In the non-unity Lewis number flames, the flamelet equations suggest a dependence on a second parameter, the diffusion of the progress variable. A new tabulation approach is proposed for the simulation of such flames with these dimensionally-reduced manifolds.

Some aspects of the ecology of the limnoplankton, with special reference to the phytoplankton. [Translation from: Svensk Botanisk Tidskrift 13(2) 129-163, 1919.]

This paper tries to develop more generally some fundamental bases for the ecological study of freshwater plankton. A special attention is given to the phytoplankton associations which can be separated out and made into groups according to their dependence upon changing environments. Plankton formations in different types of water bodies (ponds, lakes and rivers) are studied.

Comparative investigations on the respiratory physiology of euryhaline gammarids with special reference to salinity adaptation. [Translation from: Helgolaender Wissenschaftliche Meeresuntersuchungen 23(4) 485-534, 1972.]

Members of the family Gammaridae are very closely interrelated. There arises the question as to how far they also differ amongst themselves through physiological characteristics. Comparative respiratory and physiological experiments were made on the five euryhaline species Gammarus locusta, G. oceanicus, G. salinus, G. zaddachi and G. duebeni. The respiratory measurements carried out within the framework of this experiment were occupied with the relationships between oxygen consumption and body size depending on salinity. They also had the object of determing the variations in metabolic intensity after an abrupt change in the salt content of the external medium, and to establish the period of time for the process of adaptation. As the experiments were carried out polarographically in a testing plant with continuous flow-through, and the method which was applied permitted continuous recording over prolonged intervals, there could also be carried out comparisons between metabolism at rest and under activity, and the alterations of oxygen consumption during the process of moulting could be measured.

Special carbon requirement of Spirulina platensis culture. [Translation from: Materialy VII Vsesoyuznogo Rabochego Soveshchanii po Voprosu Krugovorota Veshchestv v Zamknutoi Sisteme na Osnove Zhiznedeyatel'nosti Nizshikh Organizmov p55-57. Kiev, Naukova Dumka, 1972.]

By the industrial cultivation of blue-green algae, there very much appears the important question about their carbon nutrition. Spirulina grows within the range of pH value of medium of 8.5 - 11.0. In this range of pH value in the culture medium CO2 is present in the form of bicarbonate and carbonate, which serves as principal source of carbon for the present type of algae. There is little information yet about the influence of the pH of the medium, and the form of carbon components of the medium, on the rate-increase of Spirulina. Investigations were conducted into the influence of some pH values of medium on the rate-increase of the alga Spirulina platensis.

Special Frobenius Traces in Galois Representations

This thesis studies Frobenius traces in Galois representations from two different directions. In the first problem we explore how often they vanish in Artin-type representations. We give an upper bound for the density of the set of vanishing Frobenius traces in terms of the multiplicities of the irreducible components of the adjoint representation. Towards that, we construct an infinite family of representations of finite groups with an irreducible adjoint action.

In the second problem we partially extend for Hilbert modular forms a result of Coleman and Edixhoven that the Hecke eigenvalues a_p of classical elliptical modular newforms f of weight 2 are never extremal, i.e., a_p is strictly less than 2[square root]p. The generalization currently applies only to prime ideals p of degree one, though we expect it to hold for p of any odd degree. However, an even degree prime can be extremal for f. We prove our result in each of the following instances: when one can move to a Shimura curve defined by a quaternion algebra, when f is a CM form, when the crystalline Frobenius is semi-simple, and when the strong Tate conjecture holds for a product of two Hilbert modular surfaces (or quaternionic Shimura surfaces) over a finite field.

Effects of flow regime on the young stages of Salmonid fishes. Conclusions based on results for 1977-1981

Rivers in Teesdale and its fish population have been monitored for several years. This report briefly describes the life cycle of British salmonid fishes and indicates the main ways in which this life cycle is influenced by discharge and related effects. Some highlights of the research results for 1977 - 1981 are briefly stated and proposals for future research are listed. Some practical implications of the results are discussed.

Investigations into electronic stopping regime sputtering of uranium tetrafluoride

Yields were measured for ²³⁵U sputtered from UF₄ by ¹⁶O, ¹⁹F, and ³⁵Cl over the energy range ~.12 to 1.5 MeV/ amu sing a charge equilibrated beam in the stripped beam arrangement for all the incident ions and in the transmission arrangement for ¹⁹F and ³⁵Cl. In addition, yields were measured for ¹⁹F incident in a wide range of discrete charge states. The angular dependence of all the measured yields were consistent with cosʋ. The stripped beam and transmission data were well fit by the form (Az²eqln(BƐ)/Ɛ)⁴ (where Ɛ was the ion energy in MeV/amu and z_eq(Ɛ) was taken from Zeigler(80). The fitted values of B for the various sets of data were consistent with a constant B₀, equal to 36.3 ± 2.7, independent of incident ion. The fitted values of A show no consistent variation with incident ion although a difference can be noted between the stripped beam and transmission values, the transmission values being higher.

The incident charge data were well fit by the assumptions that the sputtering yield depended locally on a power of the incident ion charge and that the sputtering from the surface is exponentially correlated to conditions in the bulk. The equilibrated sputtering yields derived from these data are in agreement with the stripped beam yields.

In addition, to aid in the understanding of these data, the data of Hakansson(80,81a,81b) were examined and contrasted with the UF₄ results. The thermal models of Seiberling(80) and Watson(81) were discussed and compared to the data.

Effects of flow regime on the young stages of salmonid fishes. Summary and conclusions based on results for 1981-1985

The main British salmonid species spawn in clean gravel in streams and rivers, many of them in the upland areas of Britain. The earliest stages of the life cycle (eggs and alevins) spend some months within the gravel of the river bed. During this period their survival rate can be strongly influenced by flow regime and by related phenomena such as movement of coarse river bed material, changes in water level and the deposition of silt. In recent years human influence upon the flow regimes of upland water courses and upon the sediment inputs to them has increased. In order to conserve and, if possible, enhance the populations of salmonid fishes a deeper understanding of the interrelationships between survival of young salmonids and flow-related phenomena is needed. The acquisition of appropriate information is the main aim of the present project, which included: Studies on silt movement and the infilling of gravel voids by fine sediments, together with initial studies on the relationship between intragravel oxygen supply rate and the survival of intragravel stages of salmonids; studies in the general field of egg washout. The latter investigated the physical background to gravel bed disruption, the examination of the physical characteristics of sites chosen for redds, dimensions of redds and burial depth of eggs relative to the size of the fish constructing the redd and a series of smaller studies on other aspects of egg washout.

O segundo tempo do regime internacional dos investimentos: a nova geração de tratados e a prevenção de controvérsias investidor-Estado

No contexto de avanço da globalização, o Investimento Estrangeiro Direto (IED) mostra-se como um dos principais veículos para a inserção internacional dos países. Como os objetivos das empresas transnacionais e dos Estados hospedeiros não são os mesmos, há a necessidade de adoção de políticas que levem à convergência. No plano legal, observou-se nas últimas décadas a consolidação do regime internacional dos investimentos, com o crescimento exponencial do número de tratados de investimento e de arbitragens investidor-Estado fundadas nos mesmos. Mas há insatisfações de parte a parte com o sistema. Por um lado, os países tentam limitar o ativismo dos árbitros mediante a revisão de seus tratados. Por outro, tanto os investidores como os Estados começam a perceber que não há vencedores reais na arbitragem, dadas as suas diversas deficiências. Nomeadamente: custos elevados, longa duração, incoerência nas decisões e desgaste para as relações investidor-Estado no longo prazo. Nesse diapasão, surgem propostas de alternativas. Pensadores do sistema, valendo-se do Planejamento de Sistemas de Disputas, têm desenvolvido Políticas de Prevenção de Controvérsias. Tais políticas fundamentam-se nas dinâmicas de busca de soluções baseadas em interesses contrapostas às baseadas na força e nos direitos seguindo processos de administração precoce de conflitos. Diversos países, em diferentes níveis de desenvolvimento, têm tido êxito na implementação dessas políticas. A difusão das melhores práticas, movimento apoiado por organizações internacionais, oferece oportunidades para a melhora da governança, através da promoção de maior coerência e coordenação nas ações do Estado, da transparência e do império da lei. O tema é de interesse para o Brasil, país que, diferentemente dos demais, nunca ratificou um único tratado de investimento. Isso porque já surgem vozes na indústria clamando por uma mudança de posição, diante da emergência do país também como um exportador de capital. Caso tal inflexão se confirme, o Brasil tem a oportunidade de tomar partido das melhores experiências internacionais, usando tais tratados como instrumentos na sua estratégia de desenvolvimento.

Investigations on phytoplankton with special reference to water usage

Experiments and observations on the phytoplankton of certain lakes in the English Lake District were made from early 1973 to the end of March, 1974. They included laboratory and lake bioassays and observations on the quantity and quality of the phytoplankton in six lakes. The introductory sections of the report are about algae, the ecology of phytoplankton and the scope of the contracted work. Laboratory bioassays on water from one lake, Blelham Tarn, showed that phosphorus, silicon (for diatoms) and organic substances forming complexes with iron were the major substances limiting the growth of the algae tested. The growth of the test algae was limited to different degrees by those substances and, to some extent, to a greater or lesser degree at different times of year. It is suggested that a relatively simple form of bioassay could give valuable information to water undertakings. Lake bioassays and other experiments were carried out by using large in situ tubular plastic enclosures. Two such investigations are described. The effects of a change in sewerage in two drainage basins on the phytoplankton of three lakes is described and some data given about changes since 1945 in three other lakes in the same overall drainage basin. These latter lakes have been affected too by changes in sewerage and by increasing inputs of domestic and agricultural wastes. Throughout, the relevance of the work done to practical problems of water usage is kept in mind and discussed. In the last section special reference is made to the largely unpredictable results of water transfers. The report ends with a note on river phytoplankton.

Management of Biesboch reservoirs for quality control with special reference to eutrophication

The three Biesbosch Reservoirs are pumped storage reservoirs, fed with rather polluted and highly eutrophic water from the River Meuse. Air injection at the bottom of the reservoirs prevents thermal stratification, which would otherwise result in serious water quality deterioration. Reservoir mixing also serves as an economic algal control measure; mixing over sufficient depth causes light to play the role of limiting factor and this, combined with zooplankton grazing, keeps the biomass of phytoplankton at acceptable levels. Special problems are caused by benthic, geosmin-producing Oscillatoria species growing on the inner embankment. Rooting up the bottom with a harrow is used as the method of control, based on underwater observations by biological staff trained as SCUBA-divers. With regard to pollutant behaviour the three reservoirs act as a series of fully mixed reactors. This enables the application of kinetic models to describe their behaviour and allows the use of a selective intake policy, e.g. for suspended solids with associated contaminants, ammonia and polynuclear aromatic hydrocarbons. A combination of selective intake and self- purification processes - enhanced by the compartmentalisation of the storage volume in three reservoirs - leads to a striking improvement for many water-quality parameters.
