Cargos comissionados da administração pública direta do Rio Grande do Norte: análise comparativa entre o perfil profissional dos cargos comissionados com vínculo funcional e sem vínculo funcional

The professional profile of public administrators in Brazil is changing very rapidly in recent years, seeking to meet the principle of efficiency by public agencies at all levels. The admission of the permanent government employee under the Public Administration is by competition, however, commissioned positions are free appointment of managers, which allows effective participation of external experts according to their respective standards and norms. In this context, this dissertation seeks to understand the main characteristics of the profile of the occupants of commissioned positions in Direct Public Administration of the State of Rio Grande do Norte, noting the differences between those with functional link with the have nots. For this study, by data collection and content analysis, a mapping of the administrative structure of the Government of the State of Rio Grande do Norte was done, i.e., the organization of the Executive Branch, which is regulated by the Complementary Law no. 163/1999 and its amendments, which consists of 53 (fifty three) entities, these 29 (twenty nine) are agencies of the direct administration and the remaining 24 (twenty four) comprises the indirect administration. With the collected data, analysis on the number of commissioned positions of each organ of the State of Rio Grande do Norte and information on education, age, length of service, gender and functional link with the direct administration was carried out. Data were available from SEARH in June/2013, when they totaled 58,733 (fifty-eight thousand seven hundred thirty-three) servers, these 2.15% (two point fifteen percent) occupy commissioned positions, corresponding to 1,262 commissioned positions under the Direct Administration, below the national average of 4% (four percent). Of total commissioned positions 64.7% (sixty-four point seven percent) have no functional link with the direct administration, while only 35.3% (thirty -five point three percent) have functional link. It was noticed that there are no clear and specific criteria for the appointments of commissioned positions in the State. They occur freely, as provided in the State Constitution. Another conclusion is the importance of Public Administration define and improve their capacity, competence and efficiency in the delivery of public services. For that it is necessary to invest in their workforce composed of permanent employees and commissioned positions to define the appropriate professional profile

A cultura de índio, seu menino, vem de longe aqui : formação histórica e territorialização dos Tremembé/CE

This dissertation is based on the ethnography of a strategic selection of three Tremembé ethnic situations, which are situated in the backlands of Acaraú and Itarema, municipalities located in Ceará State (Northeast Brazil). My main aims are the following. Firstly, I reconstitute the historical and social formation of three localities, called Lagoa dos Negros, Telhas, and Queimadas, related to a particular origin myth which refers to Almofala, an extinct colonial Aldeamento in the seashore, where the Tremembé indians and other native populations were converted and gathered under missionary administration. According to the origin myth, these three localities were set up after a strong drought which happened in 1888 (the so called three eights) when a group of Tremembé families moved to the countryside and established close to the Lagoa dos Negros and, later on, they were segmented into smaller groups which started to live in other areas and places not far from the former location. Notably, I develop an anthropological approach to understand the historical formation of these three localities. Secondly, I analyze some processes of territorialization, which were emerged from the 1980s and had important consequences to these indigenous families throughout the next two decades. This historical dimension is re-appropriated and ressignified in ethnic terms. A third point of my work is the analysis of the construction of territorialities and also the cultural and symbolic dimensions which are formulated by the Tremembé Indians who live in these localities. Therefore, I investigate some cultural traditions and rituals, such as the Torém dance, but I also examine their multiple semantics, which constitute a transversal direction throughout the history understood by the Tremembé of the different social situations I researched. To sum up, there is a process of cultural actualization, which is still going on and presents itself through the ludic sphere as well as their political and religions dimensions, which are usually associated to the ritual presentation of the Torém

Estudos analíticos dos grafoelementos do eletroencefalograma em sono: fusos do sono, ondas agudas do vértex e o gradiente de freqüência e amplitude, como indicadores de comprometimento neurológico na criança

Innumerable studies have focused been reported on the sleep spindles (SS), Sharp Vertex Waves (SVW) and REM, NREM Sleep as indicators interpreting EEG patterns in children. However, Frequency and Amplitud Gradient (FAG) is rarely cited sleep parameter in children,that occurs during NREM Sleep. It was first described by Slater and Torres, in 1979, but has not been routinely evaluated in EEG reports. The aim of this study was to assess the absence of SS, SVW and FAG, as an indication of neurological compromise in children. The sample consisted of 1014 EEGs of children referred to the Clinical Neurophysiology Laboratory, Hospital Universitário de Brasília (HUB), from January 1997 to March 2003, with ages ranging from 3 months to 12 years old, obtained in spontaneous sleep or induced by choral hydrate. The study was transversal and analytical, in which, visual analysis of EEG traces was perfumed individually and independently by two electroencephalographers without prior knowledge of the EEG study or neurological findings. After EEG selection, the investigators analyzed the medical reports in order to define and correlate neurological pattern was classified according to the presence or absence of neurological compromise, as Normal Neurological Pattern (NNP), and Altered Neurological Pattern (ANP) respectively. From the visual analysis of the EEG(s), it was possible to characterize 6 parameters: 1- FAG present (64,1%); 2- FAG absent (35,9%); 3 - normal SS (87,9%); 4 - altered SS s (12,1%); 5 - normal SVW s (95,7%); 6 - altered SVW s (4,3%). The prevalence of well-formed FAG is found in the 3 months to 5 years age group in the children with NNF. FAG was totally absent from the age of 10 years. When comparing the three sleep graphielements, it was observed that SVW and SS were predominant in children with NNF. However, FAG absent was more prevalent in the ANF than in altered SS an SVW. The statistical analysis showed that there is a strong association of FAG absent, with isolated alteration, in ANF patients, in that the prevalence ratio was 6,60. The association becomes stronger when FAG absent + altered SS(s) is considered (RP= 6,68). Chi-square test, corrected by Yates technique, showed a highly significant relation for FAG ρ= 0,00000001, for error X of 5%, or else the 95% confidence interval (ρ<0,05). Thus, the FAG absent were more expressive in ANF patient than altered SS(s) and SVW(s). The association becomes stronger in order to establish a prognostic relation, when the FAG is combined with the SS. The results os this study allow us to affirm that the FAG, when absent at ages ranging from 3 months to 5 years , is an indication of neurological compromise. FAG is an age-dependent EEG parameter and incorporated systematically, in the interpretation criteria of the EEG of children s sleep, not only in the maturational point of view, but also neurological disturbances with encephalic compromise

Contribuição à citogenética de testudines e análise de assimetria flutuante em Eretmochelys imbricata, Cheloniidae

This work has contributed to knowledge of the order Testudines from cytogenetic and morphological point of view. With regard to the aspects proposed cytogenetic characterization of the species Mesoclemmys tuberculata (n = 5), endemic to the Caatinga biomes, through conventional techniques of cytogenetics and molecular levels. This species presented 2n = 58, NF = 64, the first submetacentric pair, the second metacentric and third subtelocentric, and the other microchromosome telocentric. This species showed a nucleolar bearing pair, coincident with the 18S ribosomal rDNA and that proved to be heterochromatic. Small heterochromatic blocks were also found in the centromeres of the largest chromosomes, as well as terminal regions in most other chromosomes of the complement, that were GC +. Telomeric sequences showed variable patterns of signal intensity, with some repeats more intense in microchromosomes and subtly in the larger ones. When compared with other species of the genus, the G-banding patterns showed a marked similarity between them. The first karyotypic description of the species will aid in future studies and the understanding of evolutionary aspects of this family. From the morphological point of view, we carried out studies of fluctuating asymmetry in sea turtle Eretmochelys imbricata, using methods of benchmarking between hatchlings and adults and their implications for natural selection. Data were collected at two different times: first during the spawning female and the second during the outbreak and birth of the nest. The analyzed characteristics consisted of measurements of length and width of front and rear flippers (CANT, LANT, CPOS and LPOS) also collected data on the number of hull plates, side plates (NPL), the surrounding plates (NPCIRC), and plastron; plates power plants (NPP), inframarginais plates (NPIM). With the values of asymmetry we calculated the value of strict heritability for these traits, the calculation was based on only one parent. A nonparametric analysis Mann-Whitneywas performed to compare the groups (females X hatchlings, newborn hatchlings X dead hatchlings). Adult females showed no bilateral fluctuating asymmetry (FA = 0) on the number plates of the hull and plastron, while offspring, living and dead, showed a greater level of variation in these meristic parameters. In the analysis of females x hatchlings we found a significant difference between the levels of asymmetry in hoof plates (p=0.006) an the width of hindlimbs (p=0.001). Levels of FA suggest an accurate indicator as to the viability or maintenance of the individual to the reproductive phase. The coefficient of heritability (h2) of FA , obtained from the regression analysis, showed that both have low and not statistically significant values(p> 0.1). In the case of exclusion of the effective role of genetics in the generation of FA, reproductive strategies based on high number of subsidiaries products, such as those observed in E. imbricata seems to implicate the production of individuals with high level of developmental instability

A implementação do programa Gestão nota 10 no sistema municipal de educação em Mossoró/RN (2005 a 2009)

This research work is focused to show the changes in educational administration from the agreements between the Mossoró / RN and the Ayrton Senna Institute IAS, for education provision. Nowadays, the partnership policy is a constitutive element of the reform of the Brazilian State, which dropped its action on social policies and to strengthen its regulatory role, encouraging private participation in planning, preparation and implementation of public policies, new printing setting the political-social. In this context, the 10 Note Management Programme, developed by the IAS, is part of the neoliberal logic of modernization of public school systems, focusing on results and developing strategies for control and regulation of schools work and its efficiency, effectiveness and greater productivity. The 10 Note focuses on two dimensions: the management of learning and teaching in networking, in a managerial perspective to overcome the culture of failure (expressed as age-grade, dropout and repetition rates in) and implantation of culture of success (as measured in the improvement of the indices). To understanding the process, we have delimited as the object of study, the process of implementing them mentioned program in the city, which its objective is to analyze implications for the school community from the perspective of democratic management, adopting the dimensions of autonomy and participation in institutional processes as a criterion of analysis. From a methodological point of view, the survey was conducted from a literature review and documentary about educational policy developed in the country since the 1990´s, seeking to understand, in a dialectical perspective, the political dimensions of teaching, training and performance of the subjects involved in the school work. Besides the empirical observation, it was also used semi-structured interviews with a methodological tool for gathering information and opinions about the partnership and the implementation of the 10 Note Management Program in the county. The interviewee participants were ex-former education managers, coordinators, school managers, secretaries and teachers. Regarding the dimensions inside the analysis (autonomy and participation), the research led to the conclusion: that GEED, under the guidance of IAS promoted regulation of school autonomy, set up the selection process for exercising the office of school administration and system awards to schools, pupils and teachers, subject to results, there is mismatch between the managerial logic and the democratic management principles, that the ideological discourse of modernization of municipal management coexists with traditional practices, centralizing patronage, which ignores the democratic participation in the school decisions processes, the goals of the partnership were partially achieved, since that the city has improved over the approval and dropouts, although the approval of the Education Municipal Plan of the rules institutional (administrative, financial and educational) and the creation of the Councils observed that the school community participation is still limited, not being characterized as a coordinated intervention, capable of promoting the transformation and improvement its quality in the county. In the same way, the orientation of networking is a limit to the autonomy of schools, given the external definition of goals and strategies to be adopted, along with pressure exerted through the accountability of each school community for their achievements

Estudo de estratégias de otimização para poços de petróleo com elevação por bombeio de cavidades progressivas

The progressing cavity pump artificial lift system, PCP, is a main lift system used in oil production industry. As this artificial lift application grows the knowledge of it s dynamics behavior, the application of automatic control and the developing of equipment selection design specialist systems are more useful. This work presents tools for dynamic analysis, control technics and a specialist system for selecting lift equipments for this artificial lift technology. The PCP artificial lift system consists of a progressing cavity pump installed downhole in the production tubing edge. The pump consists of two parts, a stator and a rotor, and is set in motion by the rotation of the rotor transmitted through a rod string installed in the tubing. The surface equipment generates and transmits the rotation to the rod string. First, is presented the developing of a complete mathematical dynamic model of PCP system. This model is simplified for use in several conditions, including steady state for sizing PCP equipments, like pump, rod string and drive head. This model is used to implement a computer simulator able to help in system analysis and to operates as a well with a controller and allows testing and developing of control algorithms. The next developing applies control technics to PCP system to optimize pumping velocity to achieve productivity and durability of downhole components. The mathematical model is linearized to apply conventional control technics including observability and controllability of the system and develop design rules for PI controller. Stability conditions are stated for operation point of the system. A fuzzy rule-based control system are developed from a PI controller using a inference machine based on Mandami operators. The fuzzy logic is applied to develop a specialist system that selects PCP equipments too. The developed technics to simulate and the linearized model was used in an actual well where a control system is installed. This control system consists of a pump intake pressure sensor, an industrial controller and a variable speed drive. The PI control was applied and fuzzy controller was applied to optimize simulated and actual well operation and the results was compared. The simulated and actual open loop response was compared to validate simulation. A case study was accomplished to validate equipment selection specialist system

Desenvolvimento de tensoativos e sistemas microemulsionados para recuperação de petróleo

The high concentration of residual oil is one of the greatest problems found in petroleum mature fields. In these reservoirs, different enhanced oil recovery methods (EOR) can be used, highlighting the microemulsion injection. The microemulsion has showed to be efficient in petroleum recovery due to its ability to promote an efficient displacement of the petroleum, acting directly in the residual oil. In this way, this research has as objective the study of microemulsion systems obtained using a commercial surfactant (TP), determining microemulsion thermal stabilities and selecting points inside the pseudoternary phases diagram, evaluating its efficiencies and choosing the best system, that has the following composition: TP as surfactant (S), isopropyl alcohol as co-surfactant (C), kerosene as oil phase, water as aqueous phase, C/S ratio = 1, and 5% sodium p-toluenesulfonate as hydrotope; being observed the following parameters for the selection of the best pseudoternary phases diagram: C/S ratio, co-surfactant nature and addition of hydrotope to the system. The efficiency in petroleum recovery was obtained using two sandstone formation systems: Assu and Botucatu. The study of thermal stabilities showed that as the concentration of active matter in the system increased, the thermal stability also increased. The best thermal stability was obtained using point F (79.56 0C). The system that presented the best recovery percentile between the three selected (3) was composed by: 70% C/S, 2% kerosene and 28% water, with 94% of total recovery efficiency and 60% with microemulsion injection, using the Botucatu formation, that in a general way presented greater efficiencies as compared with the Assu one (81.3% of total recovery efficiency and 38.3% with microemulsion injection)

Estudo sistemático de estrelas variáveis na era dos grandes surveys

The interest in the systematic analysis of astronomical time series data, as well as development in astronomical instrumentation and automation over the past two decades has given rise to several questions of how to analyze and synthesize the growing amount of data. These data have led to many discoveries in the areas of modern astronomy asteroseismology, exoplanets and stellar evolution. However, treatment methods and data analysis have failed to follow the development of the instruments themselves, although much effort has been done. In present thesis, we propose new methods of data analysis and two catalogs of the variable stars that allowed the study of rotational modulation and stellar variability. Were analyzed the photometric databases fromtwo distinctmissions: CoRoT (Convection Rotation and planetary Transits) and WFCAM (Wide Field Camera). Furthermore the present work describes several methods for the analysis of photometric data besides propose and refine selection techniques of data using indices of variability. Preliminary results show that variability indices have an efficiency greater than the indices most often used in the literature. An efficient selection of variable stars is essential to improve the efficiency of all subsequent steps. Fromthese analyses were obtained two catalogs; first, fromtheWFCAMdatabase we achieve a catalog with 319 variable stars observed in the photometric bands Y ZJHK. These stars show periods ranging between ∼ 0, 2 to ∼ 560 days whose the variability signatures present RR-Lyrae, Cepheids , LPVs, cataclysmic variables, among many others. Second, from the CoRoT database we selected 4, 206 stars with typical signatures of rotationalmodulation, using a supervised process. These stars show periods ranging between ∼ 0, 33 to ∼ 92 days, amplitude variability between ∼ 0, 001 to ∼ 0, 5 mag, color index (J - H) between ∼ 0, 0 to ∼ 1, 4 mag and spectral type CoRoT FGKM. The WFCAM variable stars catalog is being used to compose a database of light curves to be used as template in an automatic classifier for variable stars observed by the project VVV (Visible and Infrared Survey Telescope for Astronomy) moreover it are a fundamental start point to study different scientific cases. For example, a set of 12 young stars who are in a star formation region and the study of RR Lyrae-whose properties are not well established in the infrared. Based on CoRoT results we were able to show, for the first time, the rotational modulation evolution for an wide homogeneous sample of field stars. The results are inagreement with those expected by the stellar evolution theory. Furthermore, we identified 4 solar-type stars ( with color indices, spectral type, luminosity class and rotation period close to the Sun) besides 400 M-giant stars that we have a special interest to forthcoming studies. From the solar-type stars we can describe the future and past of the Sun while properties of M-stars are not well known. Our results allow concluded that there is a high dependence of the color-period diagram with the reddening in which increase the uncertainties of the age-period realized by previous works using CoRoT data. This thesis provides a large data-set for different scientific works, such as; magnetic activity, cataclysmic variables, brown dwarfs, RR-Lyrae, solar analogous, giant stars, among others. For instance, these data will allow us to study the relationship of magnetic activitywith stellar evolution. Besides these aspects, this thesis presents an improved classification for a significant number of stars in the CoRoT database and introduces a new set of tools that can be used to improve the entire process of the photometric databases analysis

Diagnóstico do usuário no aprimoramento dos serviços de tecnologia da informação: um projeto de intervenção para o Ministério Público do Estado do Rio Grande do Norte

The information tecnology (IT) has, over the years, gaining prominence as a strategic element and competitive edge in organizations, public or private. In the judiciary, with the implementation of actions related to Judiciário Eletrônico, information technology (IT), definitely earns its status as a strategic element and significantly raises the level of dependence of the organs of their services and products. Increasingly, the quality of services provided by IT has direct impact on the quality of services provided by the agency as a whole. The Ministério Público do Estado do Rio Grande do Norte (MPRN) deployments shares of Electronic Government, along with an administrative reform, beyond these issues raised, caused a large increase in institutional demand for products and services provided by the Diretoria de Tecnologia da Informação (DTI), a sector responsible for the provision of IT services. Taking as starting point strategic goal set by MPRN to reach a 85% level of user satisfaction in four years, we seek to propose a method that assists in meeting the goal, respecting the capacity constraints of the IT sector. To achieve the proposed objective, we conducted a work in two distinct and complementary stages. In the first step we conducted a case study in MPRN, in which, through an internal and external diagnosis of DTI, accomplished by an action of internal consulting and one research of the user satisfaction, we seek to identify opportunities of change seeking to raise the quality perceived of the services provided by the DTI , from the viewpoint of their customers. The situational report, drawn from the data collected, fostered changes in DTI, which were then evaluated with the managers. In the second stage, with the results obtained in the initial process, empirical observation, evaluation of side projects of quality improvement in the sector, and validation with the managers, of the initial model, we developed an improved process, gazing beyond the identification of gaps in service a strategy for the selection of best management practices and deployment of these, in a incremental and adaptive way, allowing the application of the process in organs with little staff allocated to the provision of information technology services
