Lemes, Sirlei;
Caderno de Estudos , 1997, DOI: 10.1590/S1413-92511997000300003
Abstract: este artigo representou uma contribui??o ao desenvolvimento de um modelo de avalia??o de resultados e de desempenho para gest?o econ?mica da empresa pecuária. a base conceitual adotada sustenta-se no sistema de informa??o para gest?o econ?mica(gecon), principalmente na premissa de que o resultado econ?mico é o melhor indicador da eficácia empresarial. o desenvolvimento do artigo iniciou-se com a caracteriza??o da produ??o pecuária, contextualizando sua importancia econ?mica nacional e internacional. num segundo momento, pela vis?o sistêmica da empresa pecuária, identificou-se seus elementos, enfatizando principalmente o aspecto da gest?o do sistema pecuário. a seguir, delineou-se o modelo de informa??o para avalia??o de resultados e de desempenho da empresa pecuária. finalizou-se o estudo, com a identifica??o dos principais eventos de uma área de produ??o animal, caracterizando-se as estruturas de tais eventos, partindo-se da suposi??o de que o processo de avalia??o de desempenho fundamenta-se na representa??o, em termos econ?mico-financeiros, do que ocorre em termos operacionais.
Information Security Management of Web Portals Based on Joomla CMS
Samir Lemes
Computer Science , 2014,
Abstract: Information is the key asset of all organizations and can exist in many forms. It can be printed or written on paper, stored electronically, transmitted by mail or by electronic means, shown in films, or spoken in conversation. In today's competitive business environment, such information is constantly under threat from many sources, which can be internal, external, accidental, or malicious. Joomla is a very popular Content Management System (CMS) used for web page maintenance. This highly versatile software has found itself in both large corporate web portals, and simple web pages such as blogs. Such popularity increases its vulnerability to potential attacks and therefore needs an appropriate security management. ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) created the series of standards aimed at providing a model for establishing, implementing, operating, monitoring, reviewing, maintaining and improving an Information Security Management System (ISMS). This paper shows how principles set in ISO/IEC 27000 series of standards can be used to improve security of Joomla based web portals.
Poder local e rede urbana nas minas de Goiás
Lemes, Fernando Lobo;
História (S?o Paulo) , 2009, DOI: 10.1590/S0101-90742009000100014
Abstract: vila boa de goias was an administrative and political urban center with jurisdiction over a large region during the eighteenth century. up till the beginning of the nineteenth century, it was the only town (vila) of goias state, whose territory was sprinkled with many settlements, (arraiais), forming a network of small urban centers. without the status of imperial vila, these arraiais bowed before the power of vila boa de goias especially when it came to economic and political issues. in this context, what interests us most in this article is to analyze the strategies used by one urban center in being able to dominate and to guarantee the conditions and the rights to overlap its own interests upon the interests of other urban centers. transformed into an important attraction of the local elites, this privileged political condition was the aim of great efforts and intense devotion among the municipal authorities to safeguard vila boa's superiority over the existent arraiais located near the mines of goias.

Los últimos diez a os de la cultura política uruguaya: entre la participación y el desencanto
Lucía SELIOS LEMES
América Latina Hoy , 2009,
Abstract: RESUMEN: Uruguay presenta los guarismos más altos en los indicadores de cultura política en América Latina. Pero el impacto de los recientes cambios políticos y económicos puede haber afectado el patrón cultural de los uruguayos. De hecho, la crisis económica vivida en el 2002, la paulatina reestructuración del sistema de partidos y la asunción de un partido de izquierda en el gobierno, pueden estar reflejando o produciendo ciertos cambios en la cultura política de la población. Este artículo observa la evolución de la cultura política de los uruguayos durante la última década e identifica los cambios asociados a los momentos políticos y a la crisis económica. Específicamente se verifica un aumento del pesimismo, la momentánea pérdida de confianza en las instituciones políticas y el breve fortalecimiento del entramado social. ABSTRACT: Uruguay consistently scores the highest rates in Latin America in indicators relating to political culture. However it is plausible that recent political and economic changes may have affected the pattern of Uruguay’s political culture. In this respect, the economic crisis of 2002, the gradual restructuring of the party system and the rise to power of a left-wing government may either reflect or produce changes in the political culture of Uruguay’s population. This article examines the evolution of the political culture of the Uruguayans over the last decade, and identifies the changes associated with different political moments and the economic crisis. Specifically, it highlights an increase in pessimism, a momentary loss of confidence in political institutions and a brief strengthening of the social fabric
A Non-Phenomenological Model to Explain Population Growth Behaviors
Fabiano Lemes Ribeiro
Quantitative Biology , 2014,
Abstract: This paper proposes a non-phenomenological model of population growth that is based on the interactions between the individuals that compose the system. It is assumed that the individuals interact cooperatively and competitively. As a consequence of this interaction, it is shown that some well-known phenomenological population growth models (such as the Malthus, Verhulst, Gompertz, Richards, Von Foerster, and power-law growth models) are special cases of the model presented herein. Moreover, other ecological behaviors can be seen as the emergent behavior of such interactions. For instance, the Allee effect, which is the characteristic of some populations to increase the population growth rate at a small population size, is observed. Whereas the models presented in the literature explain the Allee effect with phenomenological ideas, the model presented here explains this effect by the interactions between the individuals. The model is tested with empirical data to justify its formulation. Other interesting macroscopic emergent behavior from the model proposed here is the observation of a regime of population divergence at a finite time. It is interesting that this characteristic is observed in humanity's global population growth. It is shown that in a regime of cooperation, the model fits very well to the human population growth data since 1000 A.D.
Implica??es ético-epistemológicas da negocia??o nos processos de avalia??o institucional participativa
Sordi, Mara Regina Lemes De;
Educa??o & Sociedade , 2012, DOI: 10.1590/S0101-73302012000200009
Abstract: this paper discusses the importance of alternative models of regulation of the quality of public schools in response to the purposeful evaluation models focused on student achievement on standardized tests. given the paucity of studies on public policy implementation becomes the experience of a municipal school system as a reference for the analysis of the strengths and vulnerabilities of the evaluation process implemented taking as participatory institutional focus on the negotiation meetings between the managers of the central and the actors of the schools. the aim is to identify concepts of quality and assessment governing the negotiation process and the consequences for decision making. it is observed that the actors tend to enhance the understanding of his role in negotiating and there is evidence of expanding the role and involvement of players from schools with the logic evaluation of the model with the continuity of the process.
Ecologia da ictiofauna de um córrego de cabeceira da bacia do alto rio Paraná, Brasil
Lemes, Elis Mara;Garutti, Valdener;
Iheringia. Série Zoologia , 2002, DOI: 10.1590/S0073-47212002000300007
Abstract: ecological studies were conducted in the ichthyofauna of cedro, a small headwater stream located in a degraded area of state of s?o paulo, brazil, situated in the upper paraná river basin. these are the results of two non-consecutive years observations and collections in two biotopes of that stream: a pool and a rapid. the ecological characteristics studied change in space and time. the present richness of species is high (21 species), nine of which are constant, six accessory and six accidental. the diversity is low (0.69 to 2.38), and the numeric predominance, from one to three species, occurred in both biotopes. the most frequent species are poecilia reticulata (peters, 1859) (28.1%), corydoras cf. aeneus (gill, 1858) (20.3%) and hypostomus cf. ancistroides (ihering, 1911) (19.8%). the density ranges from 0.7 to 19.8 specimens/m3. the similarity index indicates high similarity between the ichthyofauna (45.0% to 95.0%) inside the same or contiguous biotopes. the evenness (0.46 to 1.0) is comparable to those found in similar studies carried out in other streams.
Comiss?o própria de avalia??o (cpa): similaridades e dessemelhan?as no uso da estratégia na educa??o superior e em escolas do ensino fundamental
De Sordi, Mara Regina Lemes;
Avalia??o: Revista da Avalia??o da Educa??o Superior (Campinas) , 2011, DOI: 10.1590/S1414-40772011000300006
Abstract: the study aims to think about the meaning of the self evaluation commissions created as a strategy that permits institutional self- evaluation processes in higher education. it aims to establish comparisons from a rereading of the model used by sinaes in brazil higher education. the results confirm the importance of the self evaluation commissions as an instance that promotes the meeting of the social actors in collective spaces to search for the improvement of learning quality in an organized and plural form. the advantages of the use of such commissions in fundamental school education are appointed by the proximity of the self evaluation processes of the internal and external actors related to the school.

Abstract: the practice of the environmental education, although it has pawned in the “preservation of nature”, it seems to have released the knowledge of the different sciences for the understanding of the concept of nature that permeates our living. in this article, we present a mosaic of ideas and conceptions concerning the concept of nature, composed under several interpretation points, delineating part of the construction and reconstruction history of a concept that it was already different from the current conception that is hegemonic of the western world thought.
