A carreira de professor estadual no Brasil: os casos de S o Paulo e Rio Grande do Sul State school teacher career in Brazil: the cases of S o Paulo and Rio Grande do Sul
Fernando de Holanda Barbosa Filho,Samuel de abreu pessa
Revista de Administra??o Pública , 2011, DOI: 10.1590/s0034-76122011000400004
Abstract: O presente artigo, com base nas folhas de pagamentos dos professores das redes públicas estaduais do Rio Grande do Sul (RS) e de S o Paulo (SP), mostra que a remunera o dos professores das redes públicas destes estados n o está relacionada com o desempenho dos professores, sendo o tempo de servi o o fator determinante na evolu o da remunera o. O salário relativo médio de um professor da rede dos estados do Rio Grande do Sul e de S o Paulo, como fra o do PIB, é superior ao encontrado em outros países que s o considerados exemplos de bom desempenho escolar. Ou seja, n o há evidência de que o salário nestas redes esteja fora da nor-ma tomando como compara o os países da OECD. O artigo mostra, ainda, que o salário médio pago aos professores da ativa é inferior ao benefício médio concedido aos inativos e que estes apresentam um elevado custo na folha de pagamentos dos estados, superior aos 50% no Rio Grande do Sul e 35% em S o Paulo. Mais, as regras para aposentadoria dos professores no Brasil s o extremamente generosas quando comparadas com outros países do mundo. O artigo finaliza documentando a forte compress o salarial existente no magistério em compara o ao observado no mercado de trabalho gaúcho e paulista para os profissionais com curso superior. This paper establishes some stylized facts about the public educational system of two Brazilian states: Rio Grande do Sul (RS) and S o Paulo (SP). First, this paper shows that teachers' wages are not related with their productivity because wages are mainly affected by tenure. Second, teachers' average wage as fraction of GDP is higher than the one paid in other countries considered example of educational achievements, i.e., there is no evidence that the wages paid in Rio Grande do Sul and S o Paulo underpay its teachers, comparing with OCDE countries. Third, the average wage paid to teachers is inferior than the average benefit paid to retired teachers, and retirees represent a heavy burden on this states wage bill, above 50% at Rio Grande do Sul and 35% at S o Paulo. Moreover, the paper shows this states retirement rules are extremely generous comparing with other countries. Fourth, the public teachers' wage compression is stronger than the one observed in the job market for workers' with a college degree in both states.
Evolu??o da produtividade total dos fatores na economia brasileira com ênfase no capital humano - 1992-2007
Barbosa Filho, Fernando de Holanda;Pessa, Samuel de Abreu;Veloso, Fernando A.;
Revista Brasileira de Economia , 2010, DOI: 10.1590/S0034-71402010000200002
Abstract: this paper investigates the evolution of total factor productivity (tfp) for the brazilian economy between 1992 and 2007, using a measure of human capital based on microeconomic data. one of the main contributions of this paper is to construct a specific measure of human capital that allows one to quantify both the evolution of the participation of the different levels of education and experience of the labor force in total hours worked and the variation of its productivity over time. the results show that tfp increased only 11.3% between 1992 and 2007 and accounted for about 22.9% of the growth rate of gdp in the period. another important result is that the human capital of the labor force in brazil was almost stationary during the period. this was due to the fact that the increase in the participation component of the labor force was compensated by the reduction in the productivity component. finally, it is shown that the increase in the supply of more educated workers explains the decline in human capital compensation. in particular, the lack of a better educated labor force does not appear to have imposed a restriction to economic growth, since its supply increased faster than the demand.
Um estudo sobre os diferenciais de remunera??o entre os professores das redes pública e privada de ensino
Barbosa Filho, Fernando de Holanda;Pessa, Samuel de Abreu;Afonso, Luís Eduardo;
Estudos Econ?micos (S?o Paulo) , 2009, DOI: 10.1590/S0101-41612009000300006
Abstract: this paper studies the earnings differentials between public and private professors in the different levels of education. in most of the cases, there is a positive differential in favor of the private sector. this conclusion changes when we compute the present value of the work contract (pvwc). the pvwc considers all the income received during the workers life span. here, we compute the present value of the wages received in the working life with the retirement benefits. the results show that the pvcw is higher in the public sector than in the private sector. we compute the internal rate of return (irr) of the retirement system. we conclude that different retirement rules between the two sectors have a huge impact in the professors′ life earnings with a public irr higher than the private one. we also conclude that public teachers do not receive lower earnings than their private counterparts.
Transferência do Hepatozoon tupinambis, parasita do lagarto Tupinambis teguixin, para a serpente cascavel (Crotalus durissus terrificus), por intermédio do mosquito Culex fatigans
Pessa, Samuel B.;Biasi, Persio de;Puorto, Giuseppe;
Memórias do Instituto Oswaldo Cruz , 1974, DOI: 10.1590/S0074-02761974000200013
Abstract: the authors achieved a transfer of the hepatozoon tupinambis (laveran and salibeni, 1909), a parasite of the sauria: tupinambis teguixin, l., to a rattlesnake of the species crotalus durissus terrificus, feeding the latter with experimentally infected mosquitoes. the parasite maintained its morphological characteristics in the recepting animal throughout the whole observation period (about 100 days). schizogonic cysts were found in the liver of the rattlesnake.
Esporula??o do Hepatozoon caimani (Carini, 1909), parasita do Jacaré-de-papo-amarelo: Caiman Latirostris daud, no Culex dolosus (L. Arribálzaga)
Pessa, Samuel B.;Biasi, Persio de;Souza, Dulce Maria de;
Memórias do Instituto Oswaldo Cruz , 1972, DOI: 10.1590/S0074-02761972000300008
Abstract: the authors describe the sporogonic evolution of hepatozoon caimani (carini, 1909), in culex dolosus (l. arribálzaga). after describing the erythrocytic forms and the small schizogonic cysts with two merozoites, they show that the evolution of the parasite in mosquitoes is slow, taking about 24 days to form sporozoites at a temperature of 26-28oc, and a relative humidity of 80-85%. generally, two sporoblasts develop within the oocysts, one of them degenerating, while the other evolves and forms about 100 to 120 sporocysts, each containing from 15 to 20 sporozoites. no sporogonic evolution of the parasites has been achieved, neither in leeches (haementeria lutzi) nor in "barbeiros" (triatoma infestans).
Experiências s?bre a transmiss?o do Trypanosoma cruzi por sanguessugas e de tripanosomas de vertebrados de sangue frio por triatomíneos
Pessa,Samuel B.;
Revista de Saúde Pública , 1969, DOI: 10.1590/S0034-89101969000100002
Abstract: trypanosoma cruzi does not reproduce itself in the leech (haementerm lutzi pinto); the ingested trypanosomes degenerate after some time; other organisms remain apparently normal, however dying 48 hours after the feeding of the leechs. the parasite trypanosomas of the frog (t. rotatorium and t. leptodactyli) as well as those parasiting the ophidian rachidelus brazili (t. hogei) do not multiply in the intestine of the triatominae. the most resistent species (t. leptocbactyli) remains alive 72 hours after the feeding of the triatominae; the other two, however, do not survive more than 24 hours.

Susan Blum Pessa de Moura
Revista Trías , 2012,
Abstract: Este ensaio analisa a alteridade, repensando os estereótipos criados no Brasil em rela o ao negro e ao termo ra a. Demonstra como certos comportamentos s o inerentes ao ser humano em si, independente de cor de pele, sexo ou nacionalidade. Procura repensar as rela es de espelhamento e estranhamento que o outro nos traz, aproveitando-se de alguns poemas de Manuel Bandeira (Irene no céu) e Márcio Barbosa (O que n o dizia o poeminha do Manuel). Por fim, reflete sobre a identidade brasileira, indicando um exercício de educa o com esta finalidade do questionar.
Elaboration and evaluation of a new screening medium for detection and presumptive identification of extended-spectrum beta-lactamase-producing organisms (ESBL)
Silva, Carlos Henrique Pessa de Menezes e;
Brazilian Journal of Microbiology , 2000, DOI: 10.1590/S1517-83822000000400006
Abstract: the new ?-lactamases have arisen largely as a consequence of heavy use of new expanded spectrum ?-lactam antibiotics. health professionals need to be aware of the resistance problems caused by the new enzymes, and know the correct procedures to detect, prevent and control such problems. in this study, a new screening medium called ceftazidime-inositol-vancomycin-amphotericin b agar (civa) was elaborated and the microbiological performance was evaluated for the detection and presumptive identification of esbl-producing members of enterobacteriaceae. it was performed in 126 stool samples from hospitalized patients at santa monica hospital (vila velha, es, brazil), who had been heavily exposed to broad-spectrum antibiotic combinations. the bacteria were detected by the medium based on their colony colours (due to inositol fermentation). additional tests were required for correct identification of these strains. no false positive rates were detected.
Um modelo estruturado de competências e maturidade em gerenciamento de projetos
Rabechini Jr., Roque;Pessa, Marcelo Schneck de Paula;
Produ??o , 2005, DOI: 10.1590/S0103-65132005000100004
Abstract: this study presents a structured analytic model focused on project management applied to enterprise organizations. the vital importance of the topic regarding project management is pointed out, given that current enterprise status in the majority of economic branches undergoes intense technological, social and political transformations. the enterprises are evidently influenced by such transformations, being compelled to constant adjustments so as to accompany the demands for high quality in both products and services. the importance of innovation resulting from changing processes is eminent, since it constitutes the basis for value aggregation to the product or service. in this way, the improvement in management of all the organization resources is fundamental for the progress and the competitive aspect of the enterprises. however, maturity attainment in such a subject implies in ability for making consistent decisions, which can require time to develop a set of skills and, consequently, affect all the enterprise organization. this study contributes in understanding the processes for maturity achievement in project management applied to enterprise organizations. the proposed model intends to be a reference to be adopted by the organizations.

Pessa, Luciana Fontes;Moura, Maria Lucia Seidl de;
Psicologia: Teoria e Pesquisa , 2011, DOI: 10.1590/S0102-37722011000400007
Abstract: this longitudinal study aimed to analyze characteristics of maternal speech directed to children, identifying transitions of mother-child communication settings. four children from 13 to 24 months old and their mothers were observed longitudinally. the instances of maternal speech were classified as affirmative, negative, imperative and interrogative sentences and the mother-child communication settings were classified as attentional, conventional or symbolic. the percentage of time in attentional and symbolic settings showed a linear relation with the increase of baby's age in all mother-child dyads. different types of maternal sentences presented diverse patterns of development across time and in the four dyads. the study offers a contribution to the literature on maternal speech and initial language development with data from a brazilian context.
