As ações de improbidade administrativa, o foro por prerrogativa de função e o alcance ao agente político

A improbidade administrativa é um fenômeno antigo na história do Brasil, tendo suas raízes estranhadas na própria colonização do país. Nesse sentido, tornou-se indispensável a implementação de medidas para o combate à corrupção lato sensu1, mobilizando as diversas áreas do direito para tal finalidade. A promulgação da Constituição Federal da Republica de 1988 (CRFB/1988) conferiu rigidez constitucional aos meios de coibição à improbidade administrativa, estabelecendo peremptoriamente princípios e normas pertinentes ao tema, evidenciando a importância do controle dos atos praticados pelos agentes públicos. Todavia, ficou a cargo do legislador infraconstitucional regulamentar as ações de improbidade administrativa, o que ocorreu com a promulgação da Lei nº 8429/1992 (Lei de Improbidade Administrativa – LIA). A Lei regulou seus aspectos materiais, quais sejam: seus sujeitos (art. 1º e 2º), atos (art. 9, 10 e 11) e sanções (art. 12); como também seus aspectos procedimentais (art. 17). O tema central do estudo refere-se ao juízo competente para julgamento e processamento dos agentes públicos nas ações de improbidade administrativa, por eles gozarem de foro por prerrogativa de função no julgamento dos crimes comuns (responsabilidade penal) e de responsabilidade (responsabilidade política), e este ser um benefício relacionado exclusivamente com o cargo ocupado pelo agente. Neste sentido, por a ação de improbidade ser essencialmente sancionatória e dotada de aspectos políticos-administrativos, possuindo peculiaridades das duas esferas, muitos questionam a extensão da aplicação do benefício em questão levando em consideração o silêncio da lei. Visto isso, aprofundarei a discussão especificamente no que se refere aos agentes públicos, dividindo-a em dois aspectos: (1) os agentes políticos respondem por improbidade administrativa, visto já responderam no âmbito político-administrativo por crimes de responsabilidade? (2) em caso positivo, aplica-se foro de prerrogativa de função? Essas questões levantadas são alvo de bastante divergência na doutrina e, principalmente, na jurisprudência. Desta forma, o trabalho objetiva analisar se se estenderia a prerrogativa de foro às ações de improbidade administrativa visto que, mesmo constitucionalmente consagrada como ação civil, é uma ação dotada de peculiaridades relevantes, seja pelo forte conteúdo sancionatório, principalmente no que tange às penas previstas que ultrapassam as reparações pecuniárias do direito civil, seja por envolver interesses político e posições hierárquicas. Ultrapassada a questão, ainda busca analisar o ajuizamento destas ações em face dos agentes políticos, tanto em razão de sua possibilidade (visto já responderem por crimes de responsabilidade) quanto ao órgão jurisdicional competente para julgá-los (esbarrando novamente na questão da aplicação ou não da prerrogativa de foro).

A Specialized Processor for Emulating Peripherals of the PIC Microcontroller

This paper proposes and describes an architecture that allows the both engineer and programmer for defining and quantifying which peripheral of a microcontroller will be important to the particular project. For each application, it is necessary to use different types of peripherals. In this study, we have verified the possibility for emulating the behavior of peripheral in specifically CPUs. These CPUs hold a RAM memory, where code spaces specifically written for them could represent the behavior of some target peripheral, which are loaded and executed on it. We believed that the proposed architecture will provide larger flexibility in the use of the microcontrolles since this ""dedicated hardware components"" don`t execute to a special function, but it is a hardware capable to self adapt to the needs of each project. This research had as fundament a comparative study of four current microcontrollers. Preliminary tests using VHDL and FPGAs were done.

Solution properties of the de Branges differential recurrence equation

In this 1984 proof of the Bieberbach and Milin conjectures de Branges used a positivity result of special functions which follows from an identity about Jacobi polynomial sums thas was published by Askey and Gasper in 1976. The de Branges functions Tn/k(t) are defined as the solutions of a system of differential recurrence equations with suitably given initial values. The essential fact used in the proof of the Bieberbach and Milin conjectures is the statement Tn/k(t)<=0. In 1991 Weinstein presented another proof of the Bieberbach and Milin conjectures, also using a special function system Λn/k(t) which (by Todorov and Wilf) was realized to be directly connected with de Branges', Tn/k(t)=-kΛn/k(t), and the positivity results in both proofs Tn/k(t)<=0 are essentially the same. In this paper we study differential recurrence equations equivalent to de Branges' original ones and show that many solutions of these differential recurrence equations don't change sign so that the above inequality is not as surprising as expected. Furthermore, we present a multiparameterized hypergeometric family of solutions of the de Branges differential recurrence equations showing that solutions are not rare at all.

Von den Markenteilungen bis zum Emscher Landschaftspark: Freiraumverluste und Freiraumschutz im Ruhrgebiet

In der vorliegenden Arbeit werden die Erfolge und Misserfolge der Freiraumpolitik im Ruhrgebiet untersucht. Ausgangspunkte sind der Freiraumschwund, der über einen Zeitraum von fast 200 Jahren dokumentiert wird, sowie die Gegenbewegungen, die sich für den Freiraumschutz einsetzen. Nach der Vorstellung einer Freiraumtypologie werden diese Entwicklungen in detaillierten historischen Abrissen für jeden Freiraumtyp dargestellt, woraus sich eine eigene Ruhrgebietsgeschichte - aus der Perspektive der Freiflächen und ihrer Nutzer - ergibt. Folgerichtig beginnt die vorliegende Arbeit nicht mit Kohle und Eisen, sondern mit der Land- und Forstwirtschaft. Anhand historischer Quellen wird die gängige Am-Anfang-war-die-Heide-These widerlegt, denn das Ruhrgebiet war waldreich und ein produktiver Agrarraum. Landwirtschaftliche Flächen- und Waldverluste sind die Basis der Siedlungstätigkeit. Ohne die Gemeinheitsteilungen im 19. Jahrhundert wären die Stadterweiterungen und Industrieansiedlungen im Ruhrgebiet nicht möglich gewesen. Die - in Grundzügen im Ersten Weltkrieg entwickelte - Agrarpolitik mit der Förderung von Produktivitätssteigerungen und Hofaufgaben erleichterte den weiteren Entzug von Agrarflächen, und genauso wirkt heute die Liberalisierung der Agrarmärkte. Alternative Ansätze (z.B. Direktvermarktung) konnten diesen Trend noch nicht aufhalten. Auch das Baumschutzgesetz von 1922 konnte die nationalsozialistischen Kahlschläge, die Waldverluste im Zweiten Weltkrieg und durch den Wiederaufbau nicht verhindern. Erst seit der Deindustrialisierung, der Aufforstung von Halden und der Umweltbewegung nehmen Wälder wieder zu. Demgegenüber treten Ende des 19. Jahrhunderts völlig neue Freiraumtypen auf. Die bürgerschaftliche Kleingartenbewegung wurde dank ihrer Bedeutung für die Ernährung in den Städten seit dem Ersten Weltkrieg vom Staat stark unterstützt, von den Nationalsozialisten gleichgeschaltet, konnte aber in den 1950er Jahren ihren bürgerschaftlichen Charakter und ihre Stärke wieder zurückgewinnen. Auch wenn Kleingärten als bauliche Reserveflächen missbraucht werden, geschieht dies nicht mehr ohne Ersatzland. Im Unterschied hierzu wurde die Stadtparkbewegung kommunalisiert. Sodann entstanden Volksparks mit Sportanlagen, ästhetisch ausgerichtete Gartenschauen, die breit gefächerten Revierparks der 1970er Jahre und neue Parktypen im Emscher Landschaftspark. 1920 wird der Siedlungsverband Ruhrkohlenbezirk gegründet, der mit den Verbandsgrünflächen ein eigenes Instrument zum Freiraumschutz und die Kompetenz zur Fluchtlinien- bzw. Bebauungsplanung erhielt. Inzwischen darf der Verband, vor einigen Jahren in den Regionalverband Ruhr umgewandelt, zu kommunalen Planungen nur noch Stellungnahmen abgeben. Schon früh versuchte der Verband, industrielles Ödland zu begrünen. Nach den Bahndammbegrünungen vor dem Zweiten Weltkrieg hat er seit den 1950er Jahren Halden aufgeforstet, bis in den 1990er Jahren der Aufbau des Emscher Landschaftsparks begann. Zechen- und Industriebrachen werden in neue Parks, Halden und Mülldeponien in Landmarken und Freizeitlandschaften verwandelt. Zu fragen ist, was aus diesen Geschichten für die Freiraumpolitik folgt. Zwei gegensätzliche Thesen werden diskutiert: die Tragedy of the Commons, die im Gemeineigentum die Ursache ökologischer Probleme sieht, während der Common-Property-Ansatz gerade in gemeinschaftlichen Nutzungen einen Ansatz für Problemlösungen sieht. Dabei liegt eine Besonderheit von Freiräumen in ihrem hohen Öffentlichkeitsgrad, d.h. dass sie von vielen Menschen genutzt werden und gleichzeitig mehrere, z.B. produktive, ökologische, politische oder berufliche Funktionen erfüllen. Untersucht wird, inwieweit erfolgreich gesicherte Freiflächen Merkmale von stabilen Common-Property-Institutionen tragen, d.h. welche Funktionen die Freiräume erfüllen, wie ihre Nutzung geregelt ist und vor allem welchen Einfluss die Nutzer auf Entscheidungen haben. Thesenhaft lässt sich zusammenfassen, dass ein Teil der Freiräume sein Wachstum einer derzeit unverzichtbaren Funktion verdankt, nämlich der Camouflage von Müll und Altlasten, die eine bauliche Nutzung ausschließen. Andere Freiräume verdanken ihren Bestand ihren vielfältigen Nutzungen, zur Erholung, durch Denkmäler, für Veranstaltungen, aber auch der Wertsteigerung für umliegende Wohngebiete. Ein kleiner Teil der Freiräume hat tatsächlich einen Common-Property-Charakter: Kleingartenanlagen, die von bürgerschaftlichen Gruppen gegründeten Parks sowie die Flächen, die durch Bürgerinitiativen o.ä. gegen eine bauliche Umnutzung verteidigt werden. Grund genug, um die Idee eines Netzwerks von Parkvereinen aufzugreifen, die sich von bürgerschaftlicher Seite aus für Freiräume einsetzen können.

A model of road effect using line integrals and a test of the performance of two new road indices using the distribution of small mammals in an Atlantic Forest landscape

Effects of roads on wildlife and its habitat have been measured using metrics, such as the nearest road distance, road density, and effective mesh size. In this work we introduce two new indices: (1) Integral Road Effect (IRE), which measured the sum effects of points in a road at a fixed point in the forest; and (2) Average Value of the Infinitesimal Road Effect (AVIRE), which measured the average of the effects of roads at this point. IRE is formally defined as the line integral of a special function (the infinitesimal road effect) along the curves that model the roads, whereas AVIRE is the quotient of IRE by the length of the roads. Combining tools of ArcGIS software with a numerical algorithm, we calculated these and other road and habitat cover indices in a sample of points in a human-modified landscape in the Brazilian Atlantic Forest, where data on the abundance of two groups of small mammals (forest specialists and habitat generalists) were collected in the field. We then compared through the Akaike Information Criterion (AIC) a set of candidate regression models to explain the variation in small mammal abundance, including models with our two new road indices (AVIRE and IRE) or models with other road effect indices (nearest road distance, mesh size, and road density), and reference models (containing only habitat indices, or only the intercept without the effect of any variable). Compared to other road effect indices, AVIRE showed the best performance to explain abundance of forest specialist species, whereas the nearest road distance obtained the best performance to generalist species. AVIRE and habitat together were included in the best model for both small mammal groups, that is, higher abundance of specialist and generalist small mammals occurred where there is lower average road effect (less AVIRE) and more habitat. Moreover, AVIRE was not significantly correlated with habitat cover of specialists and generalists differing from the other road effect indices, except mesh size, which allows for separating the effect of roads from the effect of habitat on small mammal communities. We suggest that the proposed indices and GIS procedures could also be useful to describe other spatial ecological phenomena, such as edge effect in habitat fragments. (C) 2012 Elsevier B.V.

Definite integrals and operational methods

An operational method, already employed to formulate a generalization of the Ramanujan master theorem, is applied to the evaluation of integrals of various types. This technique provides a very flexible and powerful tool yielding new results encompassing different aspects of the special function theory. Crown Copyright (C) 2012 Published by Elsevier Inc.

Forward implied volatility expansions in LSV models

In this work we address the problem of finding formulas for efficient and reliable analytical approximation for the calculation of forward implied volatility in LSV models, a problem which is reduced to the calculation of option prices as an expansion of the price of the same financial asset in a Black-Scholes dynamic. Our approach involves an expansion of the differential operator, whose solution represents the price in local stochastic volatility dynamics. Further calculations then allow to obtain an expansion of the implied volatility without the aid of any special function or expensive from the computational point of view, in order to obtain explicit formulas fast to calculate but also as accurate as possible.

Advances in random matrix theory, zeta functions, and sphere packing

Over four hundred years ago, Sir Walter Raleigh asked his mathematical assistant to find formulas for the number of cannonballs in regularly stacked piles. These investigations aroused the curiosity of the astronomer Johannes Kepler and led to a problem that has gone centuries without a solution: why is the familiar cannonball stack the most efficient arrangement possible? Here we discuss the solution that Hales found in 1998. Almost every part of the 282-page proof relies on long computer verifications. Random matrix theory was developed by physicists to describe the spectra of complex nuclei. In particular, the statistical fluctuations of the eigenvalues (“the energy levels”) follow certain universal laws based on symmetry types. We describe these and then discuss the remarkable appearance of these laws for zeros of the Riemann zeta function (which is the generating function for prime numbers and is the last special function from the last century that is not understood today.) Explaining this phenomenon is a central problem. These topics are distinct, so we present them separately with their own introductory remarks.

Intrinsically photosensitive retinal ganglion cell function in relation to age: a pupillometric study in humans with special reference to the age-related optic properties of the lens.

BACKGROUND: The activity of melanopsin containing intrinsically photosensitive ganglion retinal cells (ipRGC) can be assessed by a means of pupil responses to bright blue (appr.480 nm) light. Due to age related factors in the eye, particularly, structural changes of the lens, less light reaches retina. The aim of this study was to examine how age and in vivo measured lens transmission of blue light might affect pupil light responses, in particular, mediated by the ipRGC. METHODS: Consensual pupil responses were explored in 44 healthy subjects aged between 26 and 68 years. A pupil response was recorded to a continuous 20 s light stimulus of 660 nm (red) or 470 nm (blue) both at 300 cd/m2 intensity (14.9 and 14.8 log photons/cm2/s, respectively). Additional recordings were performed using four 470 nm stimulus intensities of 3, 30, 100 and 300 cd/m2. The baseline pupil size was measured in darkness and results were adjusted for the baseline pupil and gender. The main outcome parameters were maximal and sustained pupil contraction amplitudes and the postillumination response assessed as area under the curve (AUC) over two time-windows: early (0-10 s after light termination) and late (10-30 s after light termination). Lens transmission was measured with an ocular fluorometer. RESULTS: The sustained pupil contraction and the early poststimulus AUC correlated positively with age (p=0.02, p=0.0014, respectively) for the blue light stimulus condition only.The maximal pupil contraction amplitude did not correlate to age either for bright blue or red light stimulus conditions.Lens transmission decreased linearly with age (p<0.0001). The pupil response was stable or increased with decreasing transmission, though only significantly for the early poststimulus AUC to 300 cd/m2 light (p=0.02). CONCLUSIONS: Age did not reduce, but rather enhance pupil responses mediated by ipRGC. The age related decrease of blue light transmission led to similar results, however, the effect of age was greater on these pupil responses than that of the lens transmission. Thus there must be other age related factors such as lens scatter and/or adaptive processes influencing the ipRGC mediated pupil response enhancement observed with advancing age.
