Abstract: A Social Environmental Accounting Research (SEAR), como é designada internacionalmente, constitui atualmente uma corrente de investiga o de extrema relevancia e atualidade, na qual se verifica um crescente envolvimento por parte dos investigadores académicos. Esta comunica o, para além de constituir um pequeno contributo para a divulga o do tema, pretende caracterizar o conceito de Responsabilidade Social Corporativa (RSC) e identificar as principais correntes de investiga o em Contabilidade.Na primeira parte, na tentativa de caracterizarmos o conceito, analisamos o alcance de algumas iniciativas internacionais, como o Pacto Global da Organiza o das Na es Unidas (ONU), as Diretrizes para Empresas Multinacionais da Organiza o para a Coopera o e o Desenvolvimento Económico (OCDE), o Livro Verde para Responsabilidade Social das Empresas apresentado pela Uni o Europeia (EU), e as Diretrizes para a elabora o de Relatórios de Sustentabilidade emanadas pela Global Report Initiative (GRI).Na segunda parte, apresentamos uma breve evolu o da investiga o relacionada com RSE realizada no domínio científico da Contabilidade. Tendo por base as diferentes leituras identificadas ao longo do trabalho, e sem se ter a pretens o de realizar um estudo exaustivo, apresentamos os suportes teóricos mais utilizados no ambito da SEAR. Trata-se de uma abordagem simplista que visa um primeiro contacto com o tema e que tem por objetivo identificar possíveis alternativas teóricas para a análise do relato social e ambiental das empresas. Foram consideradas teorias predominantes no ambito da SEAR, distinguindo-se entre Teorias de Politica Económica – a Teoria Positiva da Contabilidade e a Perspetiva Baseada nos Recurso, e Teorias Sociais e Políticas – a Teoria dos Stakeholders e a Teoria da Legitimidade.

Abstract: between 1950 and 1951, the first prophylactic campaign against chagas diseases was carried on in brazil by the so existing servi?o nacional de malária. the actions involving chemical vector control comprehended 74 municipalities along the rio grande valley, between the states of s?o paulo and minas gerais. ever since, until 1975, the activities were performed according the availability of resources, being executed with more or less regularity and coverage. at that time, chagas disease did no represent priority, in comparison with other endemic diseases prevalent in the country. even so, taking into account the accumulated data along those 25 years, the volume of work realized cannot be considered despicable. nevertheless, it was few consistent, in terms of its impact on disease transmission. in 1975, with an additional injection of resources surpassed from the malaria program, plus the methodological systematization of the activities, and with the results of two extensive national inquiries (entomologic and serologic), the activities for vector control could be performed regularly, following two basic principles: interventions in always contiguous areas, progressively enlarged, and sustainability (continuity) of the activities, until being attained determined requirements and purpose previously established. such actions and strategies lead into the exhaustion of the populations of the principal vector species, triatoma infestans, no autochthonous and exclusively domiciliary, as well as the control of the domiciliary colonization of autochthonous species important to disease transmission. vector transmission today is being considered residual, by means of some few native and peridomestic species, such as triatoma brasiliensis and triatoma pseudomaculata. there is, also, the risk of progressive domiciliation of some species before considered sylvatic, such as panstrongylus lutzi and triatoma rubrovaria. finally, there is the possibility of the occurrence of cases of h

Abstract: SPEM (Software Process Engineering Metamodel Specification) is the software processes modeling standard defined by OMG (Object Management Group). However, the process enactment support provided by this standard has many deficiencies. Therefore, the main objective of this paper is to propose a language for software process enactment based upon SPEM 2.0 concepts. First, we will present a critical analysis of the SPEM standard approach for enactment. Then, we will present xSPIDER_ML, an enactment language, and describe its structure, components and associated rules. In order to evaluate the proposed language, a case study is performed through a RUP (Rational Unified Process) process instantiation. The language presented in this paper is part of a support set of tools for flexible software process enactment. Additionally, this set of tools is in compliance with software process quality models.

Abstract: in the current scenario of knowledge, the separation between science and philosophy finds its limit, searching now a new unit. geography, in this context of knowledge, presents its failed history while modern science and, at the same time, its capacity for moving beyond the limits. lost in its lack of investigative unit, in its schizophrenia physical/human, geography deals with the nodal point of all contemporary difficulty of knowledge, in that seeks the understanding of the world unit by the relationship of man with nature. just at this point, where all historical difficulty of geographic analysis is founded, takes form a knowledge that transcends the barrier created by the split between philosophy and science.

Abstract: cortical screws are submitted to torsional forces during its insertion and removal. therefore, one of the purposes of this research was to evaluate the mechanical behavior of stainless steel cortical screws submitted to manual torsion test and automated torsion test. the secondary objective was to analyze the fracture area with a scanning electron microscope. ten cortical stainless steel screws have been used. five screws were submitted to the manual torsion test and five screws were tested on a torsion machine. their properties were calculated and the fracture area was analyzed. the manual torsion test has shown to be inaccurate for the calculation of mechanical properties. therefore, it is contraindicated for identifying the mechanical behavior of cortical stainless steel screws. the automated torsion test showed a more rigid methodology and therefore more reliable results. screws fractures, both on manual and automated torsion assays, presented no different patterns.

Abstract: objective: to test the hypothesis that left ventricular hypertrophy (lvh) reduces the electrocardiographic and functional effects of right coronary artery occlusion. methods: we analysed 215 patients (166 males and 49 women,age of 58.9±10.6 years), with occlusion of the right coronary artery without other associated lesions. there was no significant difference (p>0.05) in age and gender distribution between the 78 patients with lvh (left ventricular mass >100g/m2) (group a) when compared with the 137 patients without lvh (left ventricular mass <100g/m2) (group b). results: the electrocardiographic finding of transmural necrosis was more often found in group b patients than in group a patients (56.9% and 30.8%, respectively; p<0.05). the left ventricular function parameters of group a were better than those of group b: the ratio end-diastolic pressure/systolic pressure (edp/sp) (a: 0.108±0.036; b: 0.121±0.050; p<0.05); the end-diastolic volume index (a: 75.9±31.3ml/m2; b: 88.0±31.0ml/m2; p<0.01); the end-systolic volume index (a: 16.0±10.0ml/m2; b: 27.0 ±20.0ml/m2; p<0.001); the ejection fraction (a 78.6±10.8%; b 67.7±17.9%; p<0.001); the anteroinferior shortening (a: 43.9±10.3%; b: 35.1±12.8%; p<0.001). a higher degree of coronary tortuosity was observed in group a than in group b (78.2% and 24.1%; p<0.001) and also a more frequent absent or minimal diaphragmatic hypokinetic area (a: 80.8%; b: 54.0%; p<0.05). conclusion: lvh reduces the effects of myocardial sequela and protects lv function when right coronary occlusion develops.

Abstract: this paper presents preliminary results obtained in a greenhouse test in which blast furnace slags and other lime materials were compared as soil correctives. comparisons were made between dolomitic limestone, calcitic limestone, oyster-shell lime, slag from iron production and slag from steel production by the martin-siemens basic procedure. these materials were compared at two different rates. general application of npk fertilizers was made and the control treatment received no lime. the soybean variety abura (glycine max (l.) merril) was utilized as an indicator plant; four plants were grown in each pot. final grain production was measured and soil samples were collected, from the pots, in order to check the ph and exchangeable acidity (h+ + al+3). the results obtained showed that under the conditions of the test, the dolomitic limestone, the calcitic limestone and the oyster-shell lime were all equally efficient in their corrective effect. the slag from steel production showed an intermediary effect, while the slag from iron prodution appeared to be the least efficient. the grain yield from these treatments did not presente any statistically significant difference. the actual grinding of the materials used in the experiment seemed satisfactory. a finer grinding is not deemed necessary unless it is required by the legislation covering the commerce of soil correctives.

Abstract: Avaliou-se a severidade da mancha-de-alternária (Alternaria helianthi) em cinco genótipos de girassol (Helianthus annuus L.), em duas densidades populacionais e duas épocas de semeadura. Os experimentos foram conduzidos no campo experimental da Embrapa-Centro de Pesquisa Agropecuária dos Cerrados, em Planaltina, DF, no ano agrícola de 1998/1999, num Latossolo areno-argiloso. O delineamento experimental utilizado foi o de blocos ao acaso, num esquema fatorial de 5 x 2, com três repeti es. A porcentagem de plantas com sintomas da mancha foi estimada por meio de observa es semanais, empregandose notas de 0 a 5 nos ter os inferior, médio e superior da planta. A popula o de plantas n o influenciou na incidência de alternária. Todas as cultivares estudadas foram suscetíveis à doen a. As condi es climáticas transcorridas em cada época de semeadura modificaram a severidade da doen a.
