Musealiza??o, crítica de arte e o exercício experimental da liberdade em Mario Pedrosa
Sant'Anna, Sabrina Parracho;
Estudos Históricos (Rio de Janeiro) , 2011, DOI: 10.1590/S0103-21862011000200008
Abstract: at least, since the last two decades of the twentieth century, much has been said about the accumulation and the collectionism of material culture in contemporary societies. starting from the analysis of the work of mario pedrosa in the 1950s and from the contemporary production in art criticism, i have attempted to compare the profession by the time of its institutionalization in brazil, and today, when it is said that the profession lost strength. in this sense, i have tried to understand how criticism is changing and thus directing the reception of pedrosa's work.
Dominant screening process in the projectile electron loss for F- + Ar collisions
Sant'Anna, M. M.;
Brazilian Journal of Physics , 2006, DOI: 10.1590/S0103-97332006000400006
Abstract: a comparison between projectile electron loss cross sections for negative, f-, and positive, he+, projectiles is presented for collisions with ar target. the behavior of the two collision systems is similar for the projectile electron loss with target ionization. for projectile electron loss without target ionization (the so-called screening electron-loss process), quite different situations are presented for the studied positive and negative projectiles. for he++ ar, the loss without target ionization collision channel is negligible for intermediate-to-low energies. on the other hand, for f-+ ar, this collision channel is the dominant one in the total projectile electron loss at intermediate-to-low velocities. the roles played by coupling with the electron capture by the projectile collision channel and by the very different binding energies for negative and positive projectiles are discussed.
?Quién hace la noticia en el Parlamento brasile?o?: Análisis comparativo de las rutinas de los newsmakers del Senado federal
Sant'Anna, Francisco;
Comunicación y sociedad , 2009,
Abstract: press coverage of the brazilian parliament is done daily by a contingent of more than 200 journalists. one part of that contingent is hired by the traditional press, while another part works for the federal senate mass media of source structures (mfsf). the aim of this article is to delimit the social-professional profile, the routines, values and journalistic paradigms adopted by those professionals of the mfsf in a comparative study with their colleagues from the traditional press, as well their social representation they possess in relation to the mfsf.
Probabilistic composition of criteria for schedule monitoring
Sant'Anna, Annibal Parracho;
Pesquisa Operacional , 2010, DOI: 10.1590/S0101-74382010000300013
Abstract: time is a key factor in management. along a project execution, keeping the best completion rates, not too slow and not too fast, is a central objective but such a best rate cannot be suitably anticipated in a precise schedule. it must be determined on the job, on a comparative basis. this paper develops an evaluation system involving the measurement of schedule fitting indicators designed to deal with such conditions. this evaluation system is based on a transformation of the data into probabilities of reaching the frontier of best performances that permits precisely composing measurements on correlated attributes. this feature of the system allows for combining criteria evaluated on elementary and on aggregate levels.
Rough sets analysis with antisymmetric and intransitive attributes: classification of brazilian soccer clubs
Sant'Anna, Annibal Parracho;
Pesquisa Operacional , 2008, DOI: 10.1590/S0101-74382008000200003
Abstract: this work aims to develop alternative classifications for teams in a championship. data from the 2005 brazilian national soccer championship are analyzed. rough sets theory (rst) is employed in this analysis. by evaluating the quality of the approximation in terms of probabilities of concordance and discordance between the classification by the set of decision attributes and by the set of condition attributes of a randomly chosen pair of objects as discernible or indiscernible, the modification of rst employed allows to consider antisymmetric and intransitive relations. the balance between the numbers of goals scored by the pairs of clubs in direct confrontations is one such relation.
Data envelopment analysis of randomized ranks
Sant'Anna, Annibal P.;
Pesquisa Operacional , 2002, DOI: 10.1590/S0101-74382002000200007
Abstract: probabilities and odds, derived from vectors of ranks, are here compared as measures of efficiency of decision-making units (dmus). these measures are computed with the goal of providing preliminary information before starting a data envelopment analysis (dea) or the application of any other evaluation or composition of preferences methodology. preferences, quality and productivity evaluations are usually measured with errors or subject to influence of other random disturbances. reducing evaluations to ranks and treating the ranks as estimates of location parameters of random variables, we are able to compute the probability of each dmu being classified as the best according to the consumption of each input and the production of each output. employing the probabilities of being the best as efficiency measures, we stretch distances between the most efficient units. we combine these partial probabilities in a global efficiency score determined in terms of proximity to the efficiency frontier.
Aleatoriza??o e composi??o de medidas de preferência
Sant'Anna, Annibal Parracho;
Pesquisa Operacional , 2002, DOI: 10.1590/S0101-74382002000100006
Abstract: models for preferences, established through the ranking of the options according to isolated factors, are developed here. randomization of ranks allows us to compute the probability of each option be raised to the position of best choice. it is verified that, in horses races, measures of preference built through odds of the options to hold the first position according to some criterion or to a combination of criteria are more correlated with the measure of preference given by the final betting distribution than those given directly by the ranks.
Modelagem da produtividade e gest?o da qualidade acadêmica
Sant'Anna, Annibal Parracho;
Produ??o , 1999, DOI: 10.1590/S0103-65131999000100001
Abstract: this paper presents a dynamic hierarchical model for the production of university departments. it is a hierarchical model because technical coefficients of the academic production function are modeled as function of second level explanatory variables in such a way that such production function is allowed to change coherently from one department to another. it is dynamic in the sense that these technical coefficients are also allowed to change through time. moreover, validation and outlier selection techniques are applied to feed an automatic model revision procedure that preserves continuity in the evaluation process.
Profissionais mais competentes, politicas e práticas de gest?o mais avan?adas?
Sant'Anna, Anderson Souza;
RAE eletr?nica , 2008, DOI: 10.1590/S1676-56482008000100002
Abstract: this paper presents the results of a research program conducted to investigate the extent to which demand for professionals with increasingly more sophisticated and wide-ranging competences has been followed by an evolution in the organizational policies and practices that sustain them. using as its theoretical framework the evaluation approach to organizational modernity and a review of anglo-american and french approaches to competences ,the study presents a comparative analysis of the findings of three empirical pieces of research. after the data had been treated with multivariate and descriptive statistics, evidence was found that the demand for competences has not been accompanied by the modernization of organizational policies and practices at the same pace, suggesting the need for organizational environments that adhere more to the new professional profiles required.
"Noites abolicionistas": as mulheres encenam o teatro e abusam do piano na Cidade de Goiás (1870-1888)
Thiago SantAnna
OPSIS : Revista do Departamento de História e Ciências Sociais , 2006,
Abstract: This article analyses abolitionist practices of women from Province of Goiás in the end of slavery period. With their music knowledges, these women were in a social and politic movement in the defense of slaves. To interpretation of the documents compound of periodics, we use some of the Foucault proposals to the History and Feminist and Gender Studies.
