Lecturas marxistas de la experiencia nacional popular (o del populismo) en América Latina desde la obra de Agustín Cueva y René Zavaleta

El presente artículo tiene como objetivo analizar la producción escrita del ecuatoriano Agustín Cueva y del boliviano René Zavaleta, respecto a los debates sobre la experiencia populista y sobre la matriz nacional popular en América Latina. Se presentarán sus principales contribuciones en clave comparada a partir de dos ejes analíticos: su caracterización respecto de las condiciones del surgimiento de la experiencia populista y del sujeto político al que refieren estas experiencias y la distinción que realizan los autores entre el populismo y la matriz nacional-popular. A partir de este último eje, en el cual residen sus principales argumentaciones teóricas y su defensa de la perspectiva marxista en el escenario latinoamericano, estudiaremos sus miradas sobre la construcción de hegemonía y los procesos de democratización en América Latina. El trabajo ofrece una reflexión de dos referentes del marxismo latinoamericano, cuyo pensamiento representa un legado para la Teoría Social Latinoamericana, a modo de propuesta para la reflexión sobre la reactualización de los debates en torno a la experiencia populista de la región en la última década.

Do you know what MOOCS are? Discover a new way to improve your knowledge and skills

The potential of online learning has long afforded the hope of providing quality education to anyone, anywhere in the world. The recent development of Massive Open Online Courses (MOOCs) heralded an exciting new breakthrough by providing free academic instruction and professional skills development from the world’s leading universities to anyone with the sufficient resources to access the internet. The research in Advancing MOOCs for Development Initiative study was designed to analyze the MOOC landscape in developing countries and to better understand the motivations of MOOC users and afford insights on the advantages and limitations of MOOCs for workforce development outcomes. The key findings of this study challenge commonly held beliefs about MOOC usage in developing countries, defying typical characterizations of how people in resource constrained settings use technology for learning and employment. In fact, some of the findings are so contrary to what has been reported in the U.S. and other developed environments that they raise new questions for further investigation.

Quantum doubles from a class of noncocommutative weak Hopf algebras

The concept of biperfect (noncocommutative) weak Hopf algebras is introduced and their properties are discussed. A new type of quasi-bicrossed products is constructed by means of weak Hopf skew-pairs of the weak Hopf algebras which are generalizations of the Hopf pairs introduced by Takeuchi. As a special case, the quantum double of a finite dimensional biperfect (noncocommutative) weak Hopf algebra is built. Examples of quantum doubles from a Clifford monoid as well as a noncommutative and noncocommutative weak Hopf algebra are given, generalizing quantum doubles from a group and a noncommutative and noncocommutative Hopf algebra, respectively. Moreover, some characterizations of quantum doubles of finite dimensional biperfect weak Hopf algebras are obtained. (C) 2004 American Institute of Physics.

Synthesis and electrochemical properties of mesoporous nickel oxide

Mesoporous Ni(OH)(2) is synthesized using sodium dodecyl sulfate as a template and urea as a hydrolysis-controlling agent. Mesoporous NiO with a centralized pore-size distribution is obtained by calcining Ni(OH)(2) at different temperatures. The BET specific surface area reaches 477.7 m(2) g(-1) for NiO calcined at 250 degreesC. Structure characterizations indicate a good mesoporous structure for the nickel oxide samples. Cyclic voltammetry shows the NiO to have good capacitive behaviour due to its unique mesoporous structure when using a large amount of NiO to fabricate the electrode. Compared with NiO prepared by dip-coating and cathodic precipitation methods, mesoporous NiO with a controlled pore structure can be used in much larger amounts to fabricate electrodes and still maintain a high specific capacitance and good capacitive behaviour.

Synthesis of wormlike nanoporous nickel oxide with nanocrystalline framework for electrochemical energy storage

In this work, nanoporous nickel oxide was synthesized using anionic surfactant assembly method. Structure characterizations show that this nickel oxide possesses partly-ordered mesoporous structure with nanocrystalline pore wall. The formation mechanism of wormlike nanoporous structure is ascribed to the quasi-reverse micelle system formed by ternary phases of SDS (sodium dodecyl sulfate)/urea/water. Cyclic voltammetry shows that these nickel oxide samples possess both good capacitive behavior due to its unique nanoporous structure and very high specific capacitance due to its high surface area with electrochemical activity.

Synthesis and characterization of mesoporous nickel oxide and its application to electrochemical capacitor

Mesoporous Ni(OH)(2) was synthesized using cationic surfactant as template and urea as hydrolysis-controlling agent. Mesoporous NiO with centralized pore size distribution was obtained by calcining Ni(OH)(2) at different temperatures. The BET specific surface area reaches 477.7 m(2).g(-1) for NiO calcined at 523 K. Structure characterizations indicate the polycrystalline pore wall of mesoporous nickel oxide. The pore-formation mechanism is also deduced to be quasi-reverse micelle mechanism. Cyclic voltammetry shows the good capacitive behavior of these NiO samples due to its unique mesoporous structure when using large amount of NiO to fabricate electrode. Compared with NiO prepared by dip-coating and cathodic precipitation methods, this mesoporous NiO with controlled pore structure can be used in much larger amount to fabricate the electrode and still maintains high specific capacitance and good capacitive behavior.

Double-walled carbon nanotubes synthesized using carbon black as the dot carbon source

Double- walled carbon nanotubes (DWNTs) were synthesized used carbon black as the dot carbon source by a semi-continuous hydrogen arc discharge process. High-resolution transmission electron microscopy (HRTEM) observations revealed that most of the tubes were DWNTs with outer and inner diameters in the range of 2.67 - 4 nm and 1.96 - 3.21 nm, respectively. Most of the DWNTs were in a bundle form of about 10 - 30 nm in diameter with high purity ( about 70%) from thermal gravimetric analysis (TGA), resonant laser Raman spectroscopy, scanning electron microscopy (SEM) and TEM characterizations. It was found that carbon black as the dot carbon source could be easy controlled to synthesize one type of nanotube. A simple process combining oxidation and acid treatment to purify the DWNT bundles was used without damaging the bundles. The structure of carbon black, as the key element for influencing purity, bundle formation and purification of DWNTs, is discussed.

A GESTÃO DE RECURSOS HUMANOS: PERFIL ESTRATÉGICO OU OPERACIONAL?

Este trabalho tem como objetivo examinar o estágio atual do processo de desenvolvimento da função de Recursos Humanos (RH) e se esses papéis, ainda requeridos ou já existentes, atendem às expectativas dos diversos estratos envolvidos, auxiliando na busca de melhores resultados para as empresas e os que nelas trabalham. Nesse contexto, baseou-se na premissa de que as crescentes alterações sócio-culturais e o constante avanço tecnológico experimentado no mundo, além das modificações das condições de vida, permeiam e alteram as condições de trabalho e expectativas de convivência entre as pessoas e suas organizações, exigindo que a função Recursos Humanos busque alternativas de ação para alinhar suas estratégias às das organizações onde atua e fazendo com que o sistema de gestão de pessoas seja fonte de vantagem competitiva sustentável. Buscou-se analisar se o que uma organização faz e como o faz é fator que a distingue das demais, se sua especialização e habilidades deixam-na mais capaz, se é essa capacidade que a torna essencialmente mais competente e técnica e se, nesse quadro, o posicionamento postural de Recursos Humanos é adequado. Também procurou analisar a atuação de diversos públicos de interesse, como os envolvidos nas atividades trabalhistas-sindicais e se os novos elementos da governança corporativa são definidores de atuação estratégica para os profissionais da área estudada. Dentro dos conceitos acima, verificaram-se teorias e fatos, além de pesquisa, que resumissem e explicassem o que se sabe sobre o objeto estudado, classificando-os e sistematizando-os conforme apresentados na realidade empírica e selecionando aqueles a serem estudados, na tentativa de buscar e prever novas caracterizações dos papéis desempenhados por Recursos Humanos, que melhor os clarifiquem. A análise dos levantamentos teóricos realizados reforçou a importância das vantagens competitivas para o sucesso empresarial e a necessidade de que pessoas de conhecimento tornem-se mais produtivas na busca dessas vantagens, além de constatar que essas pessoas devem estar preparadas para atuar em contextos exigentes e complexos e o alerta de que a atuação estratégica de RH é fundamental na solidificação desse novo perfil dos empregados. As diversas funções operacionais atribuídas a Recursos Humanos, entre elas a administração da infra-estrutura e o gerenciamento da contribuição dos funcionários, devem complementar-se, agora, com as chamadas funções estratégicas, geradoras de valor, destacando-se o auxílio na definição das estratégias empresariais e sua tradução em ações de transformação e mudança. Mais do que isso se verificou a crescente preocupação de autores em aliar os recentes conceitos de governança corporativa a essa função estratégica de Recursos Humanos.(AU)

A IMPRENSA NA CONSTRUÇÃO DA IMAGEM PÚBLICA DO CANDIDATO AFFONSO PENNA NA ELEIÇÃO DE 1906

O presente trabalho tem por objetivo analisar o período de propaganda eleitoral à presidência da República de 1906, centrando seu objeto no candidato único para presidente, o mineiro, Affonso Penna. Nesse sentido procura-se trabalhar, especificamente, o papel da imprensa na candidatura e na construção da imagem pública, no transcurso entre agosto de 1905 a fevereiro de 1906, em dois jornais cariocas: o Correio da Manhã e o jornal O Paíz. Entre eles, a menção de Penna pode ser analisada apenas nas Cartas Mineiras do Correio da Manhã, a qual apresenta o percentual de 37% de conteúdos sobre o candidato. Desses, 54,5%, relacionam-se às suas caracterizações imagéticas e os 45,5% a sua candidatura. Quanto à construção da etapa teórica remete às obras que incluem o universo da comunicação, da propaganda política e ideológica, principalmente, na ótica brasileira. Procura-se, também, descrever a trajetória política de Affonso Penna, tendo como pano de fundo o ambiente político. Como método de coleta de dados, cita-se as pesquisas bibliográficas e documentais e como instrumento de investigação a análise de conteúdo.(AU)
