Revista de Administra??o Mackenzie , 2012,
Abstract: As séries financeiras s o fortemente caracterizadas pela sua volatilidade, alternando períodos de alta e baixa volatilidade, ou seja, a variancia dessas séries n o é constante, variam com o tempo. Dessa forma, as séries financeiras podem apresentar heterocedastidade condicional. O trabalho analisa o comportamento das séries dos retornos dos índices IVBX-2 e SMLL em 2008, com o objetivo de identificar a volatilidade das séries. O eixo teórico central do trabalho é a teoria dos mercados eficientes, que considera que todas as informa es relevantes já est o incorporadas nos pre os das a es; dessa forma, o pre o é uma boa medida de valor das a es. Os índices estudados s o caracterizados por representar carteiras hipotéticas compostas por a es de menor valor e menor liquidez, essas características pressup em um maior risco e um maior retorno associado a investimentos nesse tipo de carteira. A metodologia adotada foi o uso dos modelos da família ARCH. Os resultados da aplica o dos modelos indicam que as séries possuem um comportamento semelhante, com o coeficiente que mede a persistência de choques em torno de 1, e os impactos desses choques se d o de forma assimétrica, em que os choques negativos produzem um efeito maior do que choques positivos.

Abstract: O presente estudo tem como objetivo analisar a crise do meio ambiente sob uma abordagem epistemológica, ou seja, a partir do conhecimento produzido em rela o à natureza. Verifica-se que o pensamento ocidental, manifestado pelos paradigmas da Ciência Moderna, está ligado à organiza o dos sistemas econ micos que reconheceram historicamente a natureza apenas como recurso e potencial de produ o de capital, vindo a encontrar, por esta via, o limite entrópico da biosfera e, por conseguinte, do crescimento. Abordou-se o processo de constru o do conhecimento, questionando-se a possibilidade de concep o de outras perspectivas, fundadas na inseparabilidade entre sujeito-objeto, a o-pensamento e homem-natureza. é percebida a necessidade do ser humano de se re-significar no mundo, conhecendo a complexidade da natureza e pensando além da crise ecológica.

Abstract: Purpose: The aim of this study was to isolate and identify potentially pathogenic airborne fungi from Hospital das Clínicas Samuel Libanio in the city of Pouso Alegre-MG and evaluate their susceptibility to natural and industrial products. Methods: The air collection was performed by passive sedimentation in the morning during the autumn and winter seasons. Petri dishes were open as the location of air conditioning. The isolates were subjected to pathogenicity test. The identification of the fungi was performed according to the macroscopic evaluation and micromorphology. Potentially pathogenic isolates were susceptibility tested by disc diffusion method. The agents used were insecticides and industrial cleaning products and essential oils of citronella plants, lemon grass, eucalyptus and Melaleuca extracted by steam distillation method. Results: We obtained a total of 356 fungal isolates. The inside door environments were 126 (35.39%) and the outside environments were 230 (64.6%) isolates. The 22 (6.18%) isolates from the inside and 25 (6.18%) outside the hospital showed pathogenic potential. This isolates were identified as Acremonium spp., A. niger, A. terreus, A. versicolor, Curvularia sp., Penicillium sp. and Scopulariopsis sp. Susceptibility testing it was observed that most of the isolates were susceptible to the principle product containing sodium hypochlorite. Citronella oil showed enormous potential inhibition against all isolates. Already lemon grass oil was effective only against isolates of Penicillium spp. Conclusions: All genres identified are significant allergens, which can cause respiratory disease in both immunocompromised individuals such as asthmatics and people with any immune deficit. The monitoring of environmental sources should be performed, especially in special areas with immunocompromised patients. Despite efforts to try to reduce fungal infections hospital there are still flaws in the strategies employed.

Abstract: Este trabalho teve como objetivo avaliar os impactos do atual modelo de produ o agrícola, relacionando-o com o tema da seguran a alimentar. Ponderaram-se, além dos efeitos meramente econ micos, os aspectos sociais e ambientais afetados pelo fomento da agricultura químico-dependente. Constata-se que o desenvolvimento do setor agrário n o acarreta em uma distribui o mais equitativa da produ o, nem mesmo na qualidade dos alimentos disponibilizados à popula o. Verificou-se, a partir de um método de abordagem sistêmico-complexo, que a lógica do mercado reduz o poder dos pequenos agricultores, que s o dominados pela monopoliza o da produ o, regularizada pelos lobbys empresariais. Ressalta-se a importancia da análise profunda do tema, indicando a possibilidade de uma economia rural mais solidária e participativa, a partir de uma repolitiza o e reestrutura o dos modos de produ o.

Abstract: the ongoing research on freestyle flip turns requires the standardization of assessment methods and protocols. the objective of this study was to propose a standardization of the distance used for the analysis of flip-turn performance. eleven swimmers of both genders (16±3 years) participated in the study. peak force (pf) and contact time (ct) were measured using a force platform. five camcorders were installed to determine the flip-turn time at a distance of 15 (tt15) and 10 m (tt10), distance before the turn, distance to regain stroke, and time without stroke. each swimmer performed eight flip turns. the level of significance was set at p<0.01. mean pf was 1075 n and mean ct was 0.32 s. mean tt10 and tt15 were 5.52 and 8.81 s, respectively. pf and ct were associated with flip-turn performance at distances of 10 and 15 m. however, this association was stronger when analyzing time without stroke, which is part of the flip-turn phases. in conclusion, pf and ct were associated with flip-turn performance at distances of 10 and 15 m. a distance of 10 m was found to be sufficient to evaluate athletes with technical characteristics similar to those of this study. the use of the 15-m distance is recommended for swimmers with different technical characteristics, such as a longer underwater phase.

Abstract: the history of the republic proclamation in northern periphery of the brazilian empire (1822-1889), as well as the specificities of its regional cultural consequences still lack more detailed analysis. in maranh?o fin de siècle, the economic crisis of agro-export system added to the slave labor political crisis bequeathed to the republican regime early decades an intense social struggle around the definition of the citizenship boundaries, in which the racial subordination of black people is a crucial point. this paper looks closer to these deadlocks through the fictional work of the black writer raul astolfo marques (1876-1918). son of a free cafusa, the author is an outgrowth of a generation of slave descendants who have floundered in the fragility of freedom conquered in the formalism of slave abolition and equality, granted on november 15, 1889. a significant part of his literature can be understood as a systematic attempt to interpret these hopes and frustrations. the republic subject appears throughout his intellectual career, in writings e.g. "abnega??o" (1901), "a última sess?o" (1903), "o discurso do fabrício" (1903), "a opini?o da euzébia" (1904), "de coroa e barrete" (1908) e "reis republicanos" (1916). it remains to be said that his only novel a nova aurora (1913) is entirely devoted to the description of the first month of republican regime implementation. in the first part of the present paper, i ask which "versions of history" and significant episodes guide his fictional reconstruction of the november 15th 1889 consequences, focusing the short story "o discurso do fabrício" and the chronicle "a última sess?o". in the second part, i discuss the literary treatment given by the author to the problem of public policy in rodrigues alves (1902-1906) republican government, the heyday of sanitation ideology in the country, with tremendous impact in maranh?o due to the outbreak of bubonic plague in early 1904s. in this respect, combining text, pre-text and cont
