Towards Aspects Identification in Business Process Through Process Mining

In business process models, elements can be scattered (repeated) within different processes, making it difficult to handle changes, analyze process for improvements, or check crosscutting impacts. These scattered elements are named as Aspects. Similar to the aspect-oriented paradigm in programming languages, in BPM, aspect handling has the goal to modularize the crosscutting concerns spread across the models. This process modularization facilitates the management of the process (reuse, maintenance and understanding). The current approaches for aspect identification are made manually; thus, resulting in the problem of subjectivity and lack of systematization. This paper proposes a method to automatically identify aspects in business process from its event logs. The method is based on mining techniques and it aims to solve the problem of the subjectivity identification made by specialists. The initial results from a preliminary evaluation showed evidences that the method identified correctly the aspects present in the process model

Water Quality From Gualaxo Do Norte And Carmo Rivers (Minas Gerais, Brazil) After The Fundão Dam Failure

Mining waste is rich in trace elements, which present a high toxic potential and may represent a risk for aquatic ecosystems. The Fundão dam failure, considered the largest environmental disaster in the world, affected 663.2 km of watercourses, including Carmo and Gualaxo do Norte Rivers. The ore tail also affected the riverside communities, destroying villages, killing people and affecting the subsistence farming. To evaluate the influence of the mine tailing wave on the water quality of the Carmo and Gualaxo do Norte Rivers water samples were collected at nine points located in Barra Longa during the rainy season. Physicochemical parameters (conductivity, resistivity, EH, total dissolved solids, pH and temperature) and major, minor and trace elements concentrations (Ba, Co, Cr, Cu, Ni, Sc, Sr, V, Zn, As, Pb, Al, Fe, Mn, Ca, K, Mg and P) were evaluated and compared with previous studies and conformity limits established by a national resolution (CONAMA Resolution N°357/2005). Only conductivity, Fe and Mn presented non-conformity values according to CONAMA Resolution N°357/2005. These results may be related not only to the dam burst but also to the rainy season and non-detectable pollution sources. Furthermore, the decreased levels in the toxic elements in the rivers over time, may be related to its association with sediments in addition to their flux to the Atlantic Ocean. Thus, after nearly six years, the environmental and social impacts are still alive and the minerals dragged to the riverbed could bring cumulative effects for the entire environment what means an uncertain future to the Rio Doce Basin and adjacent coastal zone

Development of a Behavioral Performance Measure

Since the fifties, several measures have been developed in order to measure the performance of investments or choices involving uncertain outcomes. Much of these measures are based on Expected Utility Theory, but since the nineties a number of measures have been proposed based on Non-Expected Utility Theory. Among the Theories of Non-Expected Utility highlights Prospect Theory, which is the foundation of Behavioral Finance. Based on this theory this study proposes a new performance measure in which are embedded loss aversion along with the likelihood of distortions in the choice of alternatives. A hypothetical example is presented in which various performance measures, including the new measure are compared. The results showed that the ordering of the assets varied depending on the performance measure adopted. According to what was expected, the new performance measure clearly has captured the distortion of probabilities and loss aversion of the decision maker, ie, those assets with the greatest negative deviations from the target were those who had the worst performance

FLEXIBILITY AND UNCERTAINTY IN AGRIBUSINESS PROJECTS: INVESTING IN A COGENERATION PLANT

Concerns about global warming and high oil prices have spearheaded the search for alternate and more environmentally friendly sources of energy. One of the developments that has shown exceptional value is the increasing use of ethanol derived from biomass such as sugarcane, corn, beet and wheat. As the world's largest producer of sugar cane, Brazil has benefited from this trend to become also the largest producer of ethanol after the United States. Energy generation from biomass has also become a source of increasing interest due to growing environmental concerns and the depletion of the world's fossil fuel reserves. In this paper we analyze a sugar and ethanol producing sugar cane mill in Brazil that has both the option to expand production and invest in a more efficient bioelectricity cogeneration unit to allow the generation and sale of surplus bioelectricity generated from sugarcane bagasse, where the second option is conditional on the first one being exercised. The option to expand production is a function of the expected future prices of sugar and ethanol, while the decision to invest in the cogeneration plant will depend on future prices of energy. Both decisions are modeled as American type compound options over their respective underlying uncertainties. Many authors such as Schatzki

Metacognição como proposta pedagógica nos cursos de Terapia Ocupacional: priorização do raciocínio clínico

O raciocínio clínico é importante para a caracterização do domínio da prática em Terapia Ocupacional (TO), mas o seu aprendizado é difícil, em função de sua estrutura complexa que, ao incluir as dimensões científica, narrativa, pragmática e ética, implica na execução de variadas operações mentais pelo aluno no seu aprendizado e pelo profissional na sua atuação cotidiana. Este artigo objetiva apresentar a metacognição como recurso auxiliar para o ensino do raciocínio clínico em Terapia Ocupacional. Realizou-se estudo metodológico fundamentado em revisão narrativa que busca estabelecer interface entre o ensino do raciocínio clínico em TO e as bases teóricas e conceituais do domínio metacognitivo e da aprendizagem significativa. Percebe-se a necessidade de reflexão e pensamento crítico para fazer diagnóstico clínico em TO. A metacognição caracteriza-se pelo seu foco dirigido a esses processos e por sua capacidade de explicitá-los e de permitir o seu gerenciamento. No entanto na Terapia Ocupacional, o uso da metacognição ainda não faz parte das propostas de ensino-aprendizagem do raciocínio clínico. Dado o seu desempenho positivo em domínios similares, conclui-se ser factível o uso da metacognição para facilitar o ensino e o aprendizado do raciocínio clínico em TO

Estimates of genetic divergence in cowpea by multivariate analysis in different environments

Cowpea is a legume of great importance in the Brazilian nutrition, mainly in the Northeast region. Despite the low yield of Brazilian cowpea, the species presents a genetic potential to be explored. Thus, this work aimed to characterize the genetic diversity of cowpea genotypes by agronomic traits and select genotypes for possible crosses by multivariate analysis. Four value for cultivation and use tests were carried out with cowpea genotypes in 2005 and 2006, in the municipalities of Aquidauana, Chapadão do Sul, and Dourados, in the state of Mato Grosso do Sul. The experimental design was a complete randomized block with 20 genotypes and four replications. The evaluated traits were value for cultivation, plant lodging, pod length, grain weight of five pods, number of grains per pod, pod weight, severity of powdery mildew, and grain yield. To estimate the genetic diversity among the genotypes, the optimization methods of Tocher and UPGMA were used. The generalized distance of Mahalanobis was used as a dissimilarity measure. The clustering methods revealed genetic variability among the cowpea genotypes evaluated. The methods used formed a different number of groups for each environment. Genotypes TE97-309G-24, MNC99-542F-5, BRS Paraguaçu, BRS Paraguaçu, BR 17-Gurguéia, and CNC x 409-11F-P2 can be used to obtain promising combinations and high genetic variability

O mito contemporâneo da heroína esportiva: da guerra ao pódio

Objetivo: identificar o imaginário social transmitido pela mídia sobre atletas consideradas heroínas esportivas e identificar os discursos sobre as diferenças de gênero transmitidas pela mídia nos Jogos Olímpicos Rio 2016. Métodos: trata-se de uma pesquisa descritiva de análise documental, cuja estratégia metodológica consistiu na busca de matérias sobre heroínas Rio 2016 no site Google. As reportagens foram analisadas utilizando-se a Análise da Ordem do Discurso, de Michel Foucault. Resultados: os princípios da inversão, descontinuidade, especificidade e exterioridade, estabelecidos por Foucault, estavam presentes nos discursos analisados. Nas reportagens, as mulheres consideradas heroínas esportivas tiveram destaque quando conquistaram a primeira medalha olímpica do país de origem, quando realizaram grandes atuações em partidas decisivas e quando superaram abuso sexual. Conclusão: mesmo sendo consideradas heroínas esportivas, a imagem dessas mulheres foi associada à figura masculina. Isso evidencia a necessidade de avanços no quesito igualdades de direito entre homens e mulheres na sociedade. ABSTRACT. The contemporary myth of sports heroin: from war to podium. Objective: to identify the social imaginary transmitted by the media about women athletes considered athletic heroines and to identify the discourses on the gender differences transmitted by the media in the Rio 2016 Olympic Games. Methods: this is a descriptive research of documentary analysis, whose methodological strategy consisted in the search of stories about Rio 2016 heroines in the Google site. The reports were analyzed using the Discourse Order Analysis of Michel Foucault. Results: the principles of inversion, discontinuity, specificity and exteriority, as established by Foucault, were present in the discourses analyzed. In the reports, women considered to be sport heroines were highlighted when they won the first Olympic medal in the country of origin, when they performed great plays in decisive games and when they overcame sexual abuse. Conclusion: however, even though they were considered sport heroines, the image of these women was associated with the male figure. This highlights the need for advances in the area of equal rights between men and women in society

Hipertermia maligna en Brasil: análisis de la actividad del hotline en 2009

BACKGROUND AND OBJECTIVES: Malignant hyperthermia (MH) is a pharmacogenetic disease that causes abnormal hypermetabolic reaction to halogenated anesthetics and/or depolarizing muscle relaxants. In Brazil, there is a hotline telephone service for MH since 1991, available 24 hours a day in São Paulo. This article analyzes the activity of the Brazilian hotline service for MH in 2009. METHODS: Prospective analysis of all phone calls made to the Brazilian hotline service for MH from January to December 2009. RESULTS: Twenty-two phone calls were received: 21 from the South/Southeast region of Brazil and one from the North region. Fifteen calls were requests for general information about MH. Seven were about suspected MH acute episodes, two of which were not considered as MH. In five episodes compatible with MH, all patients received halogenated volatile anesthetics (2, isoflurane; 3, sevoflurane) and one also used succinylcholine; there were four men and one woman, with a mean age of 18 years (2-27). The problems described in the five MH episodes were tachycardia (5), increased expired carbon dioxide (4), hyperthermia (3), acidemia (1), rhabdomyolysis (1), and myoglobinuria (1). One patient received dantrolene. All five patients with MH episodes were follow-up in the intensive care unit and recovered without sequelae. Susceptibility to MH was later confirmed in two patients by in vitro muscle contracture test. CONCLUSIONS: The number of calls per year in the Brazilian hotline service for MH is still low. The characteristics of MH episode were similar to those reported in other countries. The knowledge of MH in Brazil needs to be increased.JUSTIFICATIVA Y OBJETIVOS: La Hipertermia Maligna (HM) es una enfermedad farmacogenética, con una reacción hipermetabólica anormal a los anestésicos halogenados y/o relajantes musculares despolarizantes. Desde 1991 existe un servicio hotline de atención telefónica para la HM en Brasil a disposición las 24 horas del día en São Paulo. Este artículo analiza la actividad del servicio brasileño de hotline para la HM en el 2009. MÉTODOS: Análisis prospectivo de todas las llamadas telefónicas realizadas al servicio brasileño de hotline para la HM, desde enero a diciembre de 2009. RESULTADOS: Se recibieron 22 llamadas; 21 provenientes del Sur y Sudeste de Brasil y una del Norte. Quince eran solicitudes de informaciones generales sobre la HM. Siete fueron sobre sospechas de crisis agudas de HM, de las cuales dos no fueron consideradas como HM. En las cinco crisis compatibles con la HM, todos los pacientes recibieron anestésicos inhalatorios halogenados (2 isoflurano, 3 sevoflurano) y uno también usó succinilcolina. Había cuatro hombres y una mujer, con un promedio de edad de 18 años (2-27). Los problemas descritos en las cinco crisis de HM: taquicardia (cinco), aumento del gas carbónico espirado (cuatro), hipertermia (tres), acidemia (uno), rabdomiólisis (uno) y mioglobinuria (uno). Un paciente recibió dantrolene. Todos los cinco pacientes con crisis de HM recibieron acompañamiento en la unidad de cuidados intensivos y se recuperaron sin secuelas. La susceptibilidad a la HM fue posteriormente confirmada en dos pacientes por medio del test de la contractura muscular in vitro. CONCLUSIONES: El número de llamadas por año al servicio brasileño de hotline para la HM todavía es pequeño. Las características de las crisis fueron similares a las descritas en otros países. Es necesario aumentar el conocimiento que se tiene sobre la HM en Brasil.JUSTIFICATIVA E OBJETIVOS: Hipertermia maligna (HM) é doença farmacogenética, com reação hipermetabólica anormal a anestésicos halogenados e/ou relaxantes musculares despolarizantes.
