Avaliação da aplicabilidade do modelo de maturidade de Michael Hammer para gestão de processos em tecnologia da informação

O termo gestão de processos vem ganhando relevância como forma de gestão dentre as principais organizações em todo o mundo. entretanto o assunto ainda é recente no Brasil. O aumento de demandas relacionadas a este tema gerou inúmeras tecnologias de suporte a sua gestão. o que leva as empresas à necessidade de compreenderem melhor o tema. Michael Hammer propôs um modelo de maturidade em gestão de processos. que além de proporcionar subsídios aos executivos para tomadas de decisão. permite que os envolvidos tenham uma melhor compreensão do nível de maturidade de sua organização. Este trabalho teve como objetivo estudar a viabilidade da aplicação do modelo de maturidade de Michael Hammer. usando como caso prático a área de Tecnologia da Informação de uma grande empresa brasileira. As informações para análise foram compostas por questionários e entrevistas. revisão documental e observação direta. Os resultados obtidos confirmam a importância da compreensão do nível de maturidade da organização para início ou melhoria da gestão de processos. Apesar do estudo confirmar a aplicabilidade do modelo. existem ressalvas importantes a serem consideradas por qualquer área ou organização de TI que queira medir o nível de maturidade em gestão de processos através do modelo proposto.

As aulas régias da Capitania da Bahia (1759 1827): pensamento, vida e trabalho de nobres professores

Simultanément à l' expulsion des jésuites du contrôles de l' éducaton formeI du royaume portugais, l'Ordre du 28 juin 1759 a décrété une reforme générale aux études, comme une des partie d'un ensemble de mesures modernisatoires qui ont été établisent dans le Royaume et dans ses domaines à la période comprise entre 1750 et 1777, pendant le royaume de D. José I et sous la direction de son principal ministre, Sebastião José Carvalho e MeIo, plus connu par le titre de noblesse de Marquis de Pombal. Notre thèse, locaIisée notament à la Capitanie de Bahia (Capitanie - division politique administrative du Brésil Colonie) entre les années de 1759 à 1827, a comme objet d'études les singularités du magistère bahianais et comme objectif, à partir de Ia référence théorique de l'histoire sociale des idées, comprendre comment les membres de cette nouvelle catégorie professionelle, crée pour préparés des cadres professionels mais bien qualifiés pour exercer leurs fonctions de burocratie de l'État, ont pris contact avec la pensée reforniste ilustré portugais du siècle XVIII, ont été véhiculé autant par des étrangérisés, comme par la législation pombalina (du Marquis de Pombal) et comme cet ensembIe théorique rapporté à la pensée, la vie et le travail d'enseignant de ces premiers représentants du magistère bahianais. L' analyse de la documentation (des lettres, et des ordres royals, des licences officielles pour exercer la fonction, et des serments des professeurs royal pour les plusieurs villages et capitanies; registres de correspondence reçues et envoyées par les chambres des villages; registres et correspondences expédiées par plusieurs autorités; provisions; tous les types de licences et autorisations; désignation; testament et inventaires) montre que les professeurs royals, malgré la quantité pas très nombreuses de membres, ont été extremement actifs sur les décisions les plus importantes de la période de celle qui est connue comme la crise du système colonial, qui, en Bahia, a eu ses particularités dans un mouvement d' émancipation politique seulement au mois de juillet 1823. Finallement, on a le but, dans le contenu de cette thèse de doctorat, d'offrir une connaissance sur l'histoire de l'éducation brésilienne et bahianaise qu' on retrouve encore entouré de doutes, préjugements et imterpretations équivoques qui insistent d'anaIyser le Brésil sous un stigmate du retard du royaume portugais, malgré sa production récente dans l'historiographie

The Genome Sequence of Taurine Cattle: A Window to Ruminant Biology and Evolution

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.

Cuidado de si e hermenêutica do sujeito em Michael Foucault

The work, here present, has as its objective to present in a clear and distinct manner the object of study of Michel Foucault in his last years of teaching at the College de France, namely, the care of the self. We present the care of the self in its birth, in its origin, from the character Socrates and its development until the beginning of the Christian age. With a keen eye, we present Foucault with a work of return and rescue of the care of the self to the personal and academic discussions; we propose, from the self care, to the contemporary subject a problematization of their life so that from this questioning he creates for herself ways of life that are coherence, knowledge and care with which he has of must particular, his himself. Passing by the sources that served as the source of study for Foucault to sketch the birth of care of the self, we design the form with which Foucault has dealt with the documents that speak of the care of self. We present Socrates as one who by excellence ensures that the other will give birth to the forms of knowledge and care of the self or, in other words, we present the care of the self socratic-foucauldian as a constant worry of the other to pay attention to ways in which he conducts her life, it creates for themselves ways of being and, therefore, creates ethics of existence. We present, finally, the care of the self as the cause of continuous immanence of modes of subjectivation of the subject that configure themselves in a non-accepting a determined essence, but a continually updated form . The care of the self leads to a single relationship and educator of modes of subjectivation of the subject; he creates, on the dynamics of temporality, ethical ways of living, which are sustained by an internal coherence of the subject with herself; he admits no stationary nature in the training of the subject, always wants a more beautiful work of himself; he is not isolation, he needs and is made with the other. The care of the self is the principle and the telos of battles and conquests of the subject within his temporality and existence

Efeito Kerr magneto-óptico; Ressonância ferromagnética; Acoplamento bilinear; Acoplamento biquadrático

In this work, we investigated the magnetic properties of a monocrystalline Fe thin film and of Fe(80 Å)/Cr(t)/Fe(80 Å) tri-layers, with the nonmagnetic metallic Cr spacer layer thickness varying between 9 Å < t < 40 Å. The samples were deposited by the DC Sputtering on Magnesium Oxide (MgO) substrates, with (100) crystal orientation. For this investigation, experimental magneto-optical Kerr effect (MOKE) magnetometry and ferromagnetic resonance (FMR) techniques were employeed. In this case, these techniques allowed us to study the static and dynamical magnetization properties of our tri-layers. The experimental results were interpreted based on the phenomenological model that takes into account the relevant energy terms to the magnetic free energy to describe the system behavior. In the case of the monocrystalline Fe film, we performed an analytical discussion on the magnetization curves and developed a numerical simulation based on the Stoner-Wohlfarth model, that enables the numerical adjustment of the experimental magnetization curves and obtainment of the anisotropy field values. On the other hand, for the tri-layers, we analyzed the existence of bilinear and biquadratic couplings between the magnetizations of adjacent ferromagnetic layers from measurements of magnetization curves. With the FMR fields and line width angular dependencies, information on the anisotropy in three layers was obtained and the effects of different magnetic relaxation mechanisms were evidenced. It was also possible to observe the dependence of the epitaxy of the multilayers with growth and sputtering parameters. Additionally it was developed the technique of AC magnetic susceptibility in order to obtain further information during the investigation of magnetic thin films

OSLERUS OSLERI (COBBOLD, 1876) INFECTION IN MANED WOLF (CHRYSOCYON BRACHYURUS, ILLIGER, 1815)

Oslerus osleri is a small nematode that infects the respiratory tract of domestic and wild canids and is responsible for causing chronic nodular tracheobronchitis. This paper aims to report a case of parasitism by O. osleri in a free-living maned wolf (Chrysocyon brachyurus) that was struck by a motor vehicle. Fecal samples were collected, and the presence of spiral larvae, with S-shaped tails, was observed on flotation. This characteristic was compatible with the Filaroididae Family larvae of O. osleri. Although the animal did not show clinical signs of respiratory system impairment, a tracheobronchoscopy was performed. Semitransparent nodules, 5 mm in diameter, containing adult parasites were observed in the third distal portion of the trachea, cranial to the carina. Larval morphological characteristics and the nodular locations were compatible with an O. osleri respiratory tract infection.

Stabilization of a (3+1)-dimensional soliton in a Kerr medium by a rapidly oscillating dispersion coefficient

Using the numerical solution of the nonlinear Schrodinger equation and a variational method it is shown that (3 + 1)-dimensional spatiotemporal optical solitons can be stabilized by a rapidly oscillating dispersion coefficient in a Kerr medium with cubic nonlinearity. This has immediate consequence in generating dispersion-managed robust optical soliton in communication as well as possible stabilized Bose-Einstein condensates in periodic optical-lattice potential via an effective-mass formulation. We also critically compare the present stabilization with that obtained by a rapid sinusoidal oscillation of the Kerr nonlinearity parameter.

Extra dimensions at the CERN LHC via mini-black holes: Effective Kerr-Newman brane-world effects

We solve Einstein equations on the brane to derive the exact form of the brane-world-corrected perturbations in Kerr-Newman singularities, using Randall-Sundrum and Arkani-Hamed-Dimopoulos-Dvali (ADD) models. It is a consequence of such models that Kerr-Newman mini-black holes can be produced in LHC. We use this approach to derive a normalized correction for the Schwarzschild Myers-Perry radius of a static (4+n)-dimensional mini-black hole, using more realistic approaches arising from Kerr-Newman mini-black hole analysis. Besides, we prove that there are four Kerr-Newman black hole horizons in the brane-world scenario we use, although only the outer horizon is relevant in the physical measurable processes. Parton cross sections in LHC and Hawking temperature are also investigated as functions of Planck mass (in the LHC range 1-10 TeV), mini-black hole mass, and the number of large extra dimensions in brane-world large extra-dimensional scenarios. In this case a more realistic brane-effect-corrected formalism can achieve more precisely the effective extra-dimensional Planck mass and the number of large extra dimensions-in the Arkani-Hamed-Dimopoulos-Dvali model-or the size of the warped extra dimension-in Randall-Sundrum formalism.

Stabilization of a light bullet in a layered Kerr medium with sign-changing nonlinearity

Using the numerical solution of the nonlinear Schrodinger equation and a variational method, it is shown that (3+1)-dimensional spatiotemporal optical solitons, known as light bullets, can be stabilized in a layered Kerr medium with sign-changing nonlinearity along the propagation direction.

Kerr-Newman solution as a Dirac particle

For m(2) < a(2) + q(2), with m, a, and q respectively the source mass, angular momentum per unit mass, and electric charge, the Kerr-Newman (KN) solution of Einstein's equation reduces to a naked singularity of circular shape, enclosing a disk across which the metric components fail to be smooth. By considering the Hawking and Ellis extended interpretation of the KN spacetime, it is shown that, similarly to the electron-positron system, this solution presents four inequivalent classical states. Making use of Wheeler's idea of charge without charge, the topological structure of the extended KN spatial section is found to be highly non-trivial, leading thus to the existence of gravitational states with half-integral angular momentum. This property is corroborated by the fact that, under a rotation of the space coordinates, those inequivalent states transform into themselves only after a 4π rotation. As a consequence, it becomes possible to naturally represent them in a Lorentz spinor basis. The state vector representing the whole KN solution is then constructed, and its evolution is shown to be governed by the Dirac equation. The KN solution can thus be consistently interpreted as a model for the electron-positron system, in which the concepts of mass, charge and spin become connected with the spacetime geometry. Some phenomenological consequences of the model are explored.

Axial-vector torsion and the teleparallel Kerr spacetime

In the context of the teleparallel equivalent of general relativity, we obtain the tetrad and the torsion fields of the stationary axisymmetric Kerr spacetime. It is shown that, in the slow rotation and weak-field approximations, the axial-vector torsion plays the role of the gravitomagnetic component of the gravitational field, and is thus responsible for the Lense-Thirring effect.
