Fusões e aquisições no Brasil: análise dos efeitos em mercado de capitais

This study investigated the impact caused by events horizontal mergers and acquisitions (M&As) horizontal, in the stock returns of the participating companies and competitors regarding the creation or destruction of value for those firms in Brazil, from 2001 to 2012. For this, first was used the event study methodology to estimate abnormal returns in stock prices; after was conducted an analysis multiple regression. The results of the event study showed that using sub-periods for the data, before and after the crisis period, the effects were different for the target-before negative, after positive. Regarding the acquirer and competitors, the results were constant. For acquirer firms, the returns were close to zero, while for the competitors were negative. Furthermore, the regression results regarding the bidder showed that firms invested in processes of M&As to obtain a further increase its efficiency. Furthermore, this study indicated that the leverage of the bidder plays is important for creating value in acquisitions, when they has a higher Tobin’s Q. The results of target firms showed that a small firm had a better return than large firm did.

A formação do nutricionista para atuação no SUS: um olhar sobre a produção científica obrigatória dos cursos do Rio Grande do Norte

The National Curricular Guidelines for nutrition course predict training directed to the work in the Unified Health System (SUS) and the mandatory completion of course work. The aim of this study was to analyze the formation of dieticians in Rio Grande do Norte state/Brazil to work in the SUS, from the compulsory scientific production provided for training. This is a bibliometric study, quantitative approach, performed with completion of course works of five nutrition undergraduate courses in Rio Grande do Norte state in the years 2013/2013. From the reading of the works, the following variables were collected: nature of the institution, institution administrative category, location, work title, number of authors, work format, titration of the teacher advisor, study type, area of interest, scenery of accomplishment, submission to the ethics committee, suitability of descriptors and, as pertaining to the field of public health, the subfield of public health and the theme. The pedagogical projects of the courses were read and were identified opportunities to develop research in the graduation. For detection of significant categories we applied the Pearson chisquare test. We analyzed 195 works, coming mostly belonging to universities courses (79.0%) and private institutions (56.4%). A higher frequency of articles (68.2%), developed by one student (65.6%), guided by master teachers (57.9%), with cross-sectional study design (49.2%), conducted in laboratory (25%) and without submission to the ethics committee in research (49.2%) was find. The median adequacy of descriptors was 50%. As for the interest of the study, there was a higher frequency of work in the field of public health (p <0.001), within this subfield highlighting the nutritional epidemiology (63.0%) (p <0.001) and the subject nutrition assessment (57, 4%) (p <0.001). In cut on three major areas of dietician performance, was significant performing work in the field of public health in public institutions (p <0.05). The presence of complementary activities was unanimous in the pedagogical projects of the courses. The results of the study showed some methodological weaknesses in the research approaches, as well as a hegemonic positivist training. Despite the emphasis on public health, it was noticed little approximation of policies and nutrition programs in the context of the mandatory recearch of Rio Grande do Norte state nutrition courses.

Análise estratigráfica de subsuperfície do Devoniano Inferior da Bacia do Rio do Peixe, Nordeste do Brasil

Subsurface stratigraphic analysis of Devonian strata from the Rio do Peixe Basin, newly recognized by palynological studies, has resulted in the identification of two new lithostratigraphic units assembled in the Santa Helena Group. The Pilões Formation, the lower unit, is composed mainly of dark mudstones and medium-tovery fine-grained sandstones, with minor conglomerates and breccias. The Triunfo Formation, the upper unit, comprises whitish grey, kaolinitic, coarse-grained to conglomeratic, cross stratified sandstones and conglomerates, with interbedded mudstones and fine-grained sandstones. These units were characterized using cores, sidewall and cuttings samples, conventional logs and image log, from three wells drilled by PETROBRAS, and 3D seismic data. The Pilões Formation is interpreted as prodeltaic facies, with lesser associated subaqueous talus, debrite and sandy turbidite lobe facies, distal part of fandelta and braided fluviodeltaic facies of Triunfo Formation. The Santa Helena Group corresponds to the Lower Devonian tectono-sequence deposited in a NW-SE-trending graben during a transgressiveregressive cycle. With 343 meters of thickness (isochore) in well 1-PIL-1-PB (Pilões 1), this sequence has a non-conformity at the lower boundary and its upper boundary is an unconformity with the Lower Cretaceous tectono-sequence (Rio do Peixe Group), that represents a hiatus of about 265 million years. Ignimbrites and coignimbrite breccias (Poço da Jurema volcanic breccia), related to an unknown pyroclastic volcanic event, were recognized at the northern margin of the Sousa halfgraben. Evidence from well data suggests that this event is coeval with the Devonian graben filling. The present study indicates a polyhistorical tectono-volcanosedimentary evolution of the basin. This lithostratigraphic update brings new perspectives for geological research in the Rio do Peixe Basin, as well as in other inland basins of the Northeastern of Brazil. The results of the research also contribute to the kwnoledge of the Borborema Province and western Gondwana paleogeography during the Early Devonian.

Mortalidade segundo sua causa de morte e seus determinantes: uma análise para as capitais brasileiras e municípios do nordeste do Brasil, 2000 e 2010

This dissertation considered the development of two papers, both related to mortality in Brazil. In the first article, "The context of mortality according to the three broad groups of causes of death in Brazilian capitals, 2000 and 2010", the objective was to analyze the mortality rate according to the three major groups of causes of death in Brazilian capitals. In the second article, "Typology and characteristics of mortality from external causes in the municipalities in the Northeast of Brazil, 2000 and 2010", it was built up a typology for the Northeastern municipalities taking into account information on mortality from external causes and a set of indicators related to socioeconomic, demographic, and infrastructure aspects of such municipalities, both articles for the years 2000 and 2010. Thus, we used data from the Mortality Information System of the Ministry of Health. Furthermore, it was used information from the Demographic Census for those years. The variables relating to socioeconomic and demographic conditions used in this study were those available on the home page of the United Nations Program for Development. The variables relating to socioeconomic and demographic conditions used in this study were those available on the home page of the United Nations Program for Development. Was used in Article 1 the pro-rata distribution method to accomplish the redistribution of ill-defined causes. Moreover, made use of the technique of cluster analysis with the aim of grouping the capital that had proportions of deaths from ill-defined causes similar to each other. Already in Section 2, we used the technique of Empirical Bayesian estimation; spatial statistics technique; and finally, the Grade of Membership method to find types of municipalities from information on mortality from external causes associated with socioeconomic, demographic and infrastructure variables. As the main results, it stands out in Article 1, in relation to data quality, we observed the formation of four groups of similar capital between themselves, as the proportion of illdefined causes. Regarding the behavior of mortality, according to the three major groups of causes of death, it was noted both for 2000 and for 2010 the prevalence of deaths from noncommunicable diseases for both sexes, although the reduction was identified rates in some of the capitals. Communicable diseases stood out as the second cause of death among women. Also, we found that deaths due to external causes are responsible for the second cause of death among men, as well as presenting an increase among women. As for the Article 2, stands out, in general, not just an extension of mortality from external causes in the municipalities, as well as an enlargement of the configurator stain existence of external cause deaths for the whole area of Northeast. Regarding the typology of municipalities, three vi extreme profiles were buit: the profile 1, which comprises municipalities with high rates of mortality from external causes and the best social indicators; the profile 2, that was composed of municipalities that are characterized by having low mortality rates from external causes and the lowest social indicators; and the profile 3, that brings together municipalities with intermediate mortality rates and median values considered in relation to social indicators. Although we have not seen changes in the characteristics of the profiles, we observed an increase in the proportion of municipalities that belong to the extreme profile 3, taking into account the mixed profiles.

Eu tenho os meus direitos: análise de audiências de conciliação em um JECRIM de Natal

This research aims at examining, within the scope of Legal Anthropology, the constitution processes of Criminal Small-Claims Courts-JECRIMs in Brazil seeks to discuss, from the making of ethnographic work, the relationship between forms and dynamics of Justice distribution both at national and local level. To do so, one performed an ethnography at a JECRIM in the city of Natal, analyzing resulting peculiarities arising from the works the Judge-Coordinator and all of the other Judicial Actors in order to bring to reality the proposals of Law 9.099/95. Such ethnography has also enabled the analysis of the interactions between both Judicial Actors and Claimants, with or without private attorneys. The theoretical framework included several topics, including processes of conflict legalization, performance and representation analysis, and relationships between law, morality, feeling and ritual. One sought to a critical reading of the current state of conciliation and mediation, taking into account both legal and theoretical parameters on the subject. At the end, a general guideline of State action in conflict management is drawn, revealing some aporias and contradictions when voluntary processes are made mandatory by the State-Punisher.

Posicionamento estratégico de destinos: uma análise através da percepção dos operadores de Turismo da cidade de São Paulo sobre o destino Natal, Brasil

De ese modo, el objetivo del presente estudio consistió en analizar el posicionamiento estratégico del destino Natal por medio de la percepción de los operadores de turismo de la ciudad de São Paulo, principal mercado emisor de turistas del país. El estudio de carácter descriptivo-exploratorio utilizó un abordaje cualitativo y tuvo, como universo de investigación, operadoras de turismo de la capital paulista que comercializan el destino Natal. En la colecta de datos, se utilizaron la investigación bibliográfica y el estudio de campo, siendo este último efetivado por medio de un guión de entrevista semiestruturado. Ya la técnica utilizada para el análisis de los datos fue el análisis de contenido, iniciada mediante selección del material recolectado y concluida con el proceso de categorización. Cuanto a los resultados del estudio, se percibió que el paulistano que viaja al destino Natal tiene un perfil demográfico que sugiere a la práctica del turismo sustentable, está a la busca del turismo de sol y playa, y valora las bellezas naturales del lugar. Los operadores de turismo entrevistados evaluaron, positivamente, la ciudad de Natal, y destacaron los siguientes atributos del destino: playas, bellezas naturales, hostelería, receptividad de los autóctonas, gastronomía, de entre otros. Además, los respondentes demostraron tener un fuerte encariño al destino. En lo que se refiere a los aspectos negativos, prevaleció la observancia de la ineficacia de los gobiernos locales, donde el deterioro de la malla aérea y la incipiente promoción del destino fueron apuntados como los dos principales gargalos. Al analizar la competencia, se identificó que Fortaleza, Porto de Galinhas y Maceió son los tres principales concurrentes de Natal, siendo el destino pernambucano lo que presenta mejor evaluación. Por fin, se observó que no existe una diferenciación relevante en el destino Natal.

Análise de tendência e caracterização sazonal e interanual da evapotranspiração de referência para o sudoeste da amazônia brasileira: Acre, Brasil

The objective of this research was to investigate monthly climatological, seasonal, annual and interdecadal of the reference evapotranspiration (ETo) in Acre state in order to better understand its spatial and temporal variability and identify possible trends in the region. The study was conducted with data from Rio Branco municipalities, the state capital, Tarauacá and Cruzeiro do Sul considering a 30-year period (1985-2014), from monthly data from weather stations surface of the National Institute of Meteorology. The methodology was held, first, the consistency of meteorological data. Thus, it was made the gap filling in the time series by means of multivariate techniques. Subsequently were performed statistical tests trend (Mann-Kendall) and homogeneity, by Sen's estimator of the magnitude of this trend is estimated, as well as computational algorithms containing parametric and non-parametric tests for two samples to identify from that year the trend has become significant. Finally, analysis of variance technique (ANOVA) was adopted in order to verify whether there were significant differences in average annual evapotranspiration between locations. The indirect method of Penman-Montheith parameterized by FAO was used to calculate the ETo. The results of this work through examination of the descriptive statistics showed that the ETo the annual average was 3.80, 2.92 and 2.86 mm day-1 year, to Rio Branco, Tarauacá and Cruzeiro do Sul, respectively. Featuring quite remarkable seasonal pattern with a minimum in June and a maximum in October, with Rio Branco to town one with the strongest signal (amplitudes) on the other hand, the Southern Cross presented the highest variability among the studied locations. By ANOVA it was found that the average annual statistically different for a significance level of 1% between locations, but the annual average between Cruzeiro do Sul and Tarauacá no statistically significant differences. For the three locations, the 2000s was the one with the highest ETo values associated with warmer waters of the North Atlantic basin and the 80s to lower values, associated with cooler waters of this basin. By analyzing the Mann-kendall and Sen estimator test, there was a trend of increasing the seasonal reference evapotranspiration (fall, winter and spring) on the order of 0.11 mm per decade and that from the years of 1990, 1996 and 2001 became statistically significant to the localities of Cruzeiro do Sul Tarauacá and Rio Branco, respectively. For trend analysis of meteorological parameters was observed positive trend in the 5% level of significance, for average temperature, minimum temperature and solar radiation.

Síntese e reatividade de derivados de quinoxalina visando aplicações como quimiossensores e estudo cinético por análise de imagens

Synthesis of heterocyclic compounds, as quinoxaline derivatives, has being shown to be relevant and promissor due to expressive applications in biological and technological areas. This work was dedicated to the synthesis, characterization and reactivity of quinoxaline derivatives in order to obtain new chemosensors. (L)-Ascorbic acid (1) and 2,3-dichloro-6,7- dinitroquinoxalina (2) were explored as synthetic precursors. Starting from synthesis of 1 and characterization of compounds derived from (L)-ascorbic acid, studies were performed investigating the application of products as chemosensors, in which compound 36 demonstrated selective affinity for Cu2+ íons in methanolic solution, by naked-eye (colorimetric) and UVvisible analyses. Further, initial analysis suggests that 39 a Schiff’s base derived from 36 also presents this feature. Five quinoxaline derivatives were synthesized from building block 2 through nucleophilic aromatic substitution by aliphatic amines, in which controlling the experimental conditions allows to obtain both mono- and di-substituted derivatives. Reactivity studies were carried out with two purposes: i) investigate the possibility of 47 compound being a chemosensor for anion, based on its interaction with sodium hydroxide in DMSO, using image analysis and UV-visible spectroscopy; ii) characterize kinetically the conversion of compound 44 into 46 based on RGB and multivariate image analysis from TLC data, as a simple and inexpensive qualitative and quantitative tool.

A atuação dos núcleos de apoio às pessoas com necessidades educacionais especiais no IFRN

The aim of this study was to evaluate the reality of the Service Centers for People with Special Educational Needs (NAPNEs) implanted at Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN) through a Professional Education Program in Technology for People with Special Educational Needs (TEC NEP Program). To reach the proposal we opted for an exploratory research with a qualitative approach characterized as a field of study. Data were obtained from questionnaires answered by thirteen (13) NAPNEs coordinators of different IFRN campuses and examined using content analysis. The survey results show that the creation of the TEC NEP program was an important step for inclusion policies in IFRN. However, difficulties were also identified by participants as coordinators: lack of physical infrastructure, human and material resources and financial matters, among others, as barriers to implementation and performance of NAPNEs. Keywords: TEC NEP Program, Professional Education, Inclusion, People with disabilities.

Os estados no SUAS: uma análise da capacidade institucional dos governos estaduais na assistência social

This paper deals of the effects generated by institutional designs in the behavior of political actors. The literature that discusses the implications of federal arrangements in the production of public policies to dock at two opposing arguments: (1) the federal configuration would cause dispersion and variation in service provision between subnational governments; and (2) the central government would own mechanisms to induce the provision of national policies in more homogeneous levels, similar to unitary states. The research is part of this discussion because it analyzes the effects of the institutional design of the Sistema Único de Assistência Social (SUAS) in the decisions of states in Brazil. Therefore, we analyzed the institutional capacity built by the 26 state governments after the implementation of SUAS, conceiving this system as defined mechanism of government functions and federative cooperation.It is argued that the existence of a heterogeneous institutional capacity of state governments in social assistance is a result of the autonomy contained in the institutional design of SUAS to this level of government. This freedom of action relativize the idea that the implementation of national public policy systems would generate positive (or homogeneous) effects in all subnational governments, at the same time as it preclude to generalize the premise of fragility of the states in the brazilian federal plan.

Análise do desempenho de um refrigerador doméstico funcionando com uma válvula de expansão micrométrica

Household refrigerators are equipments that represent a significant portion on the eletricity consumption of Brazilian homes. The use of these devices with low energy efficiency contributes to increase the energy consumption. The energy efficiency of a refrigerator is a function of the interaction between the coolant fluid and the components of the thermodynamic cycle. Changes in load and/or nature of the coolant may modify the condensing and/or evaporation pressures. The volumetric capacity of the compressor, the mass flow of coolant and the compression power are dependent parameters of the condensation and evaporation pressures. Thus, the expansion devices exert an importante role in the balance of these pressures, being fundamental for the better performance of the refrigeration cycle. This experimental research aims to investigate the sensitivity of the performance parameters of a household refrigerator operating with R134a and at different evaporation pressures. Therefore, a small refrigerator was instrumented with temperature, pressure sensors and other variables of interest, installed along the cooling circuit, in order to allow the thermal mapping and the evaluation of the equipment performance parameters. The variation of pressure loss in the coolant fluid resulting from the operation of the expansion valve with micrometric adjustment that modifies the evaporation temperature, influencing significantly the performance parameters of the thermodynamic refrigeration cycle.

Educação profissional e tecnológica de turismo no Brasil: análise através da percepção de docentes da rede federal de educação

The increasing pace of technological change and innovation in the labor market are important landmarks that contribute to accelerate the improvement of vocational and technological education. The need to analyze the educational processes is correlated with this dynamic in order to respond to the pedagogical processes and inherent to the labor market needs in evidence. This research theme is centered on targeted education process for tourist activity that is premised on improving the quality of services, taking as analysis parameter technological higher education in the federal education network (IF), covering the design, similarity and the differences in the courses offered, the axis of Tourism, Hospitality and Leisure instituted by the National catalog Technological Colleges and the National Science and Technology Department in Brazil. The research also aims to investigate the design and implementation of these upper and search courses emphasize the importance of training for students. The research is exploratory qualitative from survey data on the websites of the Ministry of Education, was adopted as a research procedure the questionnaire sent to coordinators via institutional email courses, to collect data in order to obtain results about Technological Education Federal Education Network. The survey results show that most courses offered by technological higher education in the federal education network (IF) is the Tourism Management, we noted that this option is the result of the ease in assembling the structure of the courses in relation to others; teachers have this type of education a more practical option for students coming to the conclusion that the courses undergo a fragile process, stating that the formation lies only in the student's interest in obtaining the higher diploma course without concern for quality this academic background, demand for courses is by being fast graduation. Even as a result of the design and development of Political and Pedagogical projects it was found that they are built in the most collegial many of them without the participation of a pedagogue; about the permanence of the student identified a high dropout rate, occurring in some campuses to migration to the traditional higher education, a BA in tourism. Thus, this work aimed to contextualize the technological higher education in tourism, presenting the reality of the current situation, aiming to discuss the phenomenon from the description made by all subjects and the research object, knowledge of which is due to experience the federal education network that was able to bring the essence of the matter.

Arquitetura, cidade e território no Brasil colonial: a contribuição dos carmelitas calçados da Bahia e Pernambuco (1580-1800)

This study investigates the religious group named 'shoe wearing carmelites' (or Calced Carmelites) from Brazil´s Order of Carmo, from 1580 until 1800, in the Capitaincy of Bahia de Todos os Santos (Recôncavo, city of Salvador and Sergipe) and in the Capitaincy of Pernambuco (Alagoas, Pernambuco and Itamaracá). The study does not include the religious group known as the 'Reformed' Carmelites from Goiana, Recife and Paraíba convents. The Order of Carmo is a religious order from the Roman Catholic Church, founded in the 12th century. By the 16th century they were split into 'Calced' and 'Discalced'. In 1580 the Calced ones came from Portugal to Brazil, built convents in urban areas and were able to acquire slaves, farms and other assets. As any other religious order, the Carmelites had their modus operandi. This work emphasizes the way they operated or acted in the city, either individually or in association with other Carmelite religious foundations elsewhere (networking). Their action affected, although indirectly, the building of some specific aspects of the architecture, the city and the territory in colonial Brazil. The main objective of this study is to demonstrate the impact of the Calced Carmelites from Bahia and Pernambuco upon the territory of colonial Brazil, which is analyzed according to three scales: 1) the region or interurban; 2) the city or intraurban; 3) the building or the architecture. The research employs the comparative method of analysis, especially for the architectural scale. The work demonstrates that although not acting as architects or urbanists, the Carmelites contributed to the formation of the colonial territory of Brazil, behaving as a well-articulated and hierarchized religious network, from an economic and social perspective. Moreover, they influenced the emergence and growth of several colonial urban nuclei, from Bahia to Pernambuco, mainly in the surroundings of their religious buildings. Finally, it is very clear this religious order’s contribution to colonial architecture, as it can be seen by the architectural characteristics of the convents and churches which have been analyzed, many of which still stand in a good state of conservation nowadays.
