Trem de alta velocidade RJ-SP: estudo de caso sobre sua n��o implementa����o durante os governos Lula e Dilma

This work refers to one of the greatest infrastructure projects planned by the Federal Public Administration entitled Trem de Alta Velocidade RJ-Campinas (TAV Brasil) [High Speed Rail Rio de Janeiro ��� Campinas], also know as bullet train. The intent of this research is not to explore the technical issues of the project bu the description of some details contributes for a better understanting of the evolved technology. The focus of this work is found under the actions promoted by diverse political actors in such enterprise as well as the context which made the public grant not possible along the two mandates of President Lula and the first one of President Dilma Rousseff. This contemporary matter required a huge documentary investigation performed by available material on the internet, news report of the most important press vehicles in the country, essays and articles published by experts. Some people involved in this policy process were interviewed. These inputs enriched the data explaining the conceived actions and structure of the project by the federal government. The results and final considerations target the complexity of the project and the TAV auctions failure from 2010 to 2014, suggesting further researches concerning the retaking of the bullet train project.

Pr��ticas e comportamentos de lideran��a na gest��o dos recursos humanos escolares: estudo de caso numa escola da Regi��o Aut��noma da Madeira

Num mundo globalizado e complexo em que o capital humano assume centralidade em tem��ticas associadas �� lideran��a das organiza����es e consequente gest��o de recursos humanos, em termos escolares, urge perceber que percep����es t��m os liderados, pessoal docente e n��o docente, acerca das pr��ticas e comportamentos da lideran��a. O estudo compreendeu uma fase explorat��ria que envolveu a pesquisa de teorias e trabalhos desenvolvidos, nomeadamente, monografias, livros, teses e artigos, de forma a construir-se um quadro te��rico de refer��ncia acerca da gest��o de recursos humanos e da lideran��a. O modelo de orienta����o privilegiado foi o das ���5 Pr��ticas da Lideran��a Exemplar��� de Kouzes e Posner (2009). A investiga����o, de natureza quantitativa e qualitativa, privilegiou como estrat��gia de pesquisa o estudo de caso, incidindo sobre uma Escola B��sica dos 2�� e 3�� Ciclos da Regi��o Aut��noma da Madeira. Como instrumentos de recolha de dados, foram utilizados a an��lise de conte��do e o inqu��rito por question��rio. Foi administrado, ao pessoal docente e n��o docente da escola, o question��rio LPI - Observer (Leadership Practice Inventory) desenvolvido por Kouzes e Posner (2003b). A an��lise de conte��do recaiu sobre dois documentos da escola, a saber, o Projecto Educativo de Escola e o Plano Anual de Escola. Conclu��mos que, na opini��o dos inquiridos, as pr��ticas de lideran��a que dever��o ser privilegiadas por um l��der eficaz s��o ���Permitir que os outros ajam��� e ���Encorajar a vontade���. Os inquiridos consideram que o l��der adopta pr��ticas de uma lideran��a exemplar, no entanto, a sua frequ��ncia �� inferior ��s que dever��o ser observadas num l��der eficaz. A pr��tica mais frequentemente observada, no l��der, �� ���Permitir que os outros ajam���. Por ��ltimo, por categoria, verificou-se que �� o Pessoal Docente que percepciona mais frequentemente comportamentos de lideran��a exemplar no l��der.

Da promessa �� realidade: a cidade potiguar do s��culo XIX, a partir do olhar da elite

The purpose of this research is to apprehend the perception that the ruling elite, especially the Presidents of the province of Rio Grande do Norte/Brazil, had about the potiguar city, that is, the urban localities existing in the province along the 19th century. By interweaving political, administrative, socioeconomic and spatial aspects, the study of this perception involves two distinct moments, which are also linked: a moment of apprehension of the city, that is, how the elite seizes, describes and criticizes the city; and, a second moment, which occurs simultaneously or after the first moment, of intervention in the city, in which the elite exposes its vision and projects for the city and for the territory. Rather than describing the potiguar city in itself, the research is an attempt to reveal how it was perceived along this process from a particular standpoint or discourse, official and elitist, which did not correspond necessarily or completely to what it was in reality. We tried to understand, always through the lens of the discourse, how the ruling elite perceived the potiguar city based on what their members thought about other urban realities, particularly of the advanced countries; how, within an integrated vision, this city was characterized in political, administrative, socioeconomic and spatial terms and how it consolidated itself along the period established for the research. Qualitative and historical in nature, this study was also methodologically developed based upon bibliographical and documental research. Given the fact that this research works with descriptions, comparisons and interpretations, it was necessary to make use of tools such as the discourse analysis in order to apprehend, as much as possible, what lay behind the words of the elite. The primary sources used were essentially the official documents produced by the Presidents of the province, as well as other documents written by top government officials and other members of the administration staff, all of them composing the so-called ruling elite of Rio Grande do Norte. Secondary sources were books and other publications, theses and dissertations, among others. The research made possible the identification of a certain perception of the potiguar city in the 19th century, which is certainly limited because it is grounded on a specific discourse - that of the political and administrative elite, but which, in spite of such a limitation, is still useful to understand the city and its evolution along the period established, among other noteworthy remarks

Estudo sobre a participa����o de rodedores na cadeia de transmiss��o de Leishmania infantum (Protozoa: Trypanosomatidae) no Rio Grande do Norte

American visceral leishmaniasis is a zoonosis caused by Leishmania infantum and transmitted by the bite of the sand flies Lutzomia longipalpis.The main domestic reservoir is the dog, while foxes and opposums are the known wild reservoirs. However, identification of natural infections with L. infantum in rodents appears for need of investigating the participation of these rodents how source of infection of the parasite. In the present work the Leishmania infantum infection was investigated in rodents captured in Rio Grande do Norte, aiming at to offer subsidies to the understanding of the epidemic chains of LVA in the State. Thirteen Galea spixii were distributed in four groups, being G1 the group control with four animals and the others, G2, G3 and G4, with three animals each. Those animals were intraperitoneally inoculated with 107 promastigotas of L. infantum and accompanied for, respectively, 30, 90 and 180 days. Weekly the animals were monitored as for the corporal weight and rectal temperature. At the end of each stipulated period the animals were killed. Blood were used for determination of the parameters biochemical and haematological, PCR, ELISA, microscopic examination and cultivation in NNN medium. Liver, spleen and lymph node were used in Giemsa-stained impression and cultivation in NNN medium. Liver and spleen fragments were still used in PCR and histopathological, respectively. At the same time 79 rodents of the species Rattus rattus, Bolomys lasiurus, Oligoryzomys nigripis, Oryzomys subflavus and Trichomys apereoides were captured in the Municipal districts of Brejinho, Campo Grande, Coronel Ezequiel, Passa e Fica and V��zea for identification of natural infection with L. infantum. Evidence of infection was checked by direct examination of Giemsa-stained impression of liver, spleen and blood and culture of these tissues in NNN medium. Antibodies were researched by ELISA. They were not found differences among the weigh corporal final, rectal temperature and biochemical and haematological parameters of the Galea spixii controls and infected. The rectal temperature of the animals varied from 36OC to 40OC. For the first time values of the haematocrit (33,6% to 42,8%), hemoglobin (10,2 to 14,5g/dl), erythrocyts number (4,67x106 to 6,90x106/mm3), total leukocytes (0,9x103 to 9,2x103/mm3), platelets (49x103 to 509x103/mm3) total proteins (1,56 to 6,06 g/dl), albumin (1,34 to 3,05 g/dl) and globulins (0,20 to 3,01 g/dl) of the Galea spixii were determined. The lymphocytes were the most abundant leucocytes. Infection for L. infantum was diagnosed in two animals euthanasied 180 days after the infection. In one of the animals was also identified antibodies anti-Leishmania. The parasite was not found in none of the five other species of rodents captured. Galea spixii are resistant to the infection for L. infantum and they are not good models for the study for visceral leishmaniose, although they can act as infection sources. More studies are necessary to determine the paper of the rodents in the epidemic chain of transmission of the visceral leishmaniose in the State of Rio Grande do Norte

Uma Lectina D-lactose espec��fica da esponja marinha Cinachyrella apion: purifica����o, caracteriza����o e intera����o com Leishmania chagasi

Four different sponge species were screened using Ouchterlony agarose gel and immunodiffusion tests to identify cross-reactivity with the polyclonal antibody IgG anti-deglicosilated CvL, a lectin from Cliona varians. Crude extract from the sponge Cinachyrella apion showed cross-reactivity and also a strong haemmaglutinating activity towards human erythrocytes of all ABO groups. Thus, it was submitted to acetone fractionation, IgG anti-deglicosilated CvL Sepharose affinity chromatography, and Fast Protein Liquid Chromatography (FPLC-AKTA) gel filtration on a Superose 6 10 300 column to purify a novel lectin. C. apion lectin (CaL) agglutinated all types of human erythrocytes with preference for papainized type A and O erythrocytes. The haemagglutinating activity is independent of Ca2+, Mg2+ and Mn2+ ions, and it was strongly inhibited by the disaccharide D-lactose, up to a minimum concentration of 6.25 mM. CaL molecular mass determined by FPLC-AKTA gel filtration on a Superose 12 10 300 column and SDS gel electrophoresis was approximately 124 kDa, consisting of eight subunits of 15.5 kDa, assembled by hydrophobic interactions. The lectin was relatively heat- and pH-stable. Leishmania chagasi romastigotes were agglutinated by CaL, indicating that lactose receptors could be presented in this parasite stage. These findings are indicative of the physiological defense roles of CaL and its possible use in the antibiosis of pathogenic protozoa
