Pretendemos estudar quais os traços desadaptativos de personalidade que se relacionam com os sintomas depressivos, a afectividade positiva e negativa, numa amostra de 187 estudantes universitários, entre os 18 e os 43 anos. Calculámos as correlações entre as escalas de padrões de personalidade e as escalas de padrões graves de personalidade do Inventário Multiaxial clínico de Millon II (MCMI-II) com os sintomas depressivos avaliados pela Escala de Depressão do Centro de Estudos Epidemiológicos e com a afectividade positiva e negativa avaliadas pela Escala de Afectividade Positiva e Afectividade Negativa. Realizámos uma análise da regressão múltipla utilizando as escalas de padrões de personalidade do MCMI-II como predictores e o resultado na CES-O, como variável dependente. Obtivemos uma correlação significativa entre os padrões de personalidade borderline, masoquista, esquizotípico, negativista e evitante e paranóide e os sintomas depressivos. A afectividade negativa apresenta-se também positivamente correlacionada com os padrões dependente e esquizóide. A afectividade positiva correlacionou-se significativa e positivamente com os padrões histriónico e narcisista e negativamente com os padrões esquizóide, esquizotípico, negativista, borderline, evitante e masoquista. Na análise de regressão, o padrão borderline prevê a presença de sintomas depressivos e os padrões sádico e dependente também, mas num sentido negativo. /ABSTRACT: We intendend to study wich personality traits relate to depressiva symptoms, and positive and negative affectivity, in a sample of 187 university students, between 18 and 43 years. We did the correlation between the personality patterns scales and the personality patterns of severe personality with the depressive symptoms measured by the Center for Epidemiologic Studies Depression Scale and the positive and negative affectivity measured by the Positive Affect and Negative Affect Shedule. We did a multiple regression analysis using the personality patterns scale of Millon Clinical Multiaxial lnventory (MCMI-II) as predictors and the result of CES-D, as dependent variable. We obtained a significant correlation between the borderline, masochist, schizotypal, negativistic, avoidant and paranoid personality patterns and the depressive symptoms. Negative affectivity relates also positively with dependent and schizoid patterns. Positive affectivity correlated significant and positively with histrionic and narcissistic personality patterns and negatively with schizoid, schizotypal, negativistic, borderline, avoidant and masochist personality patterns. ln the regression analysis, the borderline pattern predicts the presence of depressive symptoms as well as the sadistic and dependent, but in the negative sense.

Em 2015, o Estado do Pará inseriu-se na rede nacional de avaliação de variedades portaenxerto selecionadas pelo Programa de Melhoramento Genético de Citros da Embrapa Mandioca e Fruticultura - PMG Citros. Essas variedades têm como ênfase principal a tolerância à seca e o controle do huanglongbing (HLB, ex-greening). No Município de Capitão Poço, em parceria com citricultores, foram instalados os primeiros ensaios. Este trabalho avaliou, na Fazenda Ornela, a formação de um pomar de laranjeira 'pera' em combinação com seis porta-enxertos: limoeiro 'cravo santa cruz', tangerineira 'Sunki tropical' citrandaris 'riverside' e 'san diego', híbridos LVK x LCR - 010 e TSKC x CTSW - 033. O experimento foi disposto em blocos casualizados, onde cada porta-enxerto foi um tratamento, com quatro repetições e dez plantas por parcela experimental. Diante dos resultados obtidos das análises biométricas dos dois primeiros anos de desenvolvimento, pode-se afirmar que o citrandaris 'riverside' vem se destacando como porta-enxerto para laranjeira 'pera'.

Air quality in animal production environment has been refereed as an interesting point for studies in environmental control systems with the focus both to the animal health which live in total confinement, as to the workers. The objective of this research was to determine the variation on the aerial environmental quality in two types of broiler housing: conventional (Gc) and tunnel type (Gt). The total dust values in both houses offered adequate rearing conditions to the birds; however, regarding the inhale dust in the air was above the limits recommended for humans. Carbon monoxide concentration in the heating phase during the evaluated period was above the 10 ppm maximum recommended, and it was higher during the cold season in Gt house (30 ppm) when compared to the Gc house (18 ppm). Ammonia concentration peaks in the air were above the 20 ppm recommended from the 20th day of production in both houses and in daily average, for a period higher in Gt (4h30) when compared to Gt (2h45). Only traces of nitrate oxide and methane were found while carbonic dioxide gas concentration evaluated during daytime met the limits allowed for both birds and labor.

Problems identified in the study and analysis of the phonology of Brazilian Indian languages belonging to the Macro-Jê branch such as Kaingang, Maxakali, and Mebengokre led the author to confirm the accuracy of some intuitions on the part of Piggott (1992) and Rice (1993) on dealing with relations between nasality and sonorancy (D'Angelis 1998). The applicability of the approach to the distinct processes of nasality and nasalization in Portuguese was verified with surprising results that recover some intuitions of Trubetzkoy (1939) and contribute to reconfirm the Mattoso Câmara's (1953; 1970) considerations, but at the same time go beyond them. This article presents the result of this investigation and its conclusions that suggest the validity and the necessity of reexamining even the phonemic inventory of the Portuguese language, an issue not at all questioned in the teaching of phonology, to take into account the linguistic changes in the phonological system of that language in the last fifty years.

The development and use of techniques that extend the life vase of the flowers, maintaining the quality of the product, is essential for reducing postharvest losses. The objective of this work was to evaluate different solutions for maintenance, associated or not to sucrose, in maintaining the postharvest quality of chrysanthemum stems. The treatments used distilled water, 8-HQC to 100 mg L-1, 8-HQC to 100 mg L-1 + sucrose 50 g L-1, 8-HQC to 200 mg L-1, 8-HQC to 200 mg L-1 + sucrose 50 g L-1. Physical assessments were made: color, fresh mass and relative water content; chemical evaluations: reducing sugars and pigments, and qualitative assessments: turgidity, color of the flowers, and number of buttons, open flowers and partially open flowers. The combination of 8-HQC 200 mg L-1 + sucrose 50 g L-1 was the best performance that made for maintaining the quality of flower stems, favoring the opening of buttons and turgidity of petals. Sucrose contributed to better maintenance of the reserve substances in the shaft, which had increased the flower vase life.

This study examined the influence of three polymerization cycles (1: heat cure - long cycle; 2: heat cure - short cycle; and 3: microwave activation) on the linear dimensions of three denture base resins, immediately after deflasking, and 30 days after storage in distilled water at 37± 2ºC. The acrylic resins used were: Clássico, Lucitone 550 and Acron MC. The first two resins were submitted to all three polymerization cycles, and the Acron MC resin was cured by microwave activation only. The samples had three marks, and dimensions of 65 mm in length, 10 mm in width and 3 mm in thickness. Twenty-one test specimens were fabricated for each combination of resin and cure cycle, and they were submitted to three linear dimensional evaluations for two positions (A and B). The changes were evaluated using a microscope. The results indicated that all acrylic resins, regardless of the cure cycle, showed increased linear dimension after 30 days of storage in water. The composition of the acrylic resin affected the results more than the cure cycles, and the conventional acrylic resin (Lucitone 550 and Clássico) cured by microwave activation presented similar results when compared with the resin specific for microwave activation.

One of the effects of the globalized world is a strong tendency to eliminate differences, promoting a planetary culture. Education systems are particularly affected, undergoing strong pressure from international studies and evaluations, inevitably comparative, and sadly competitive. As a result, one observes the gradual elimination of cultural components in the definition of education systems. The constitution of new social imaginaries becomes clear; imaginaries empty of historical, geographical and temporal referents, characterized by a strong presence of the culture of the image. The criteria of classification establish an inappropriate reference that has as its consequence the definition of practices and even of education systems. On the other hand, resistance mechanisms, often unconscious, are activated seeking to safeguard and recover the identifying features of a culture, such as its traditions, cuisine, languages, artistic manifestations in general, and, in doing so, to contribute to cultural diversity, an essential factor to encourage creativity. In this article, the sociocultural basis of mathematics and of its teaching are examined, and also the consequences of globalization and its effects on multicultural education. The concept of culture is discussed, as well as issues related to culture dynamics, resulting in the proposition of a theory of transdisciplinar and transcultural knowledge. Upon such basis the Ethnomathematics Program is presented. A critique is also made of the curriculum presently used, which is in its conception and detailing, obsolete, uninteresting and of little use. A different concept of curriculum is proposed, based on the communicative (literacy), analytical (matheracy), and material (technoracy) instruments.

PURPOSE: To evaluate the sensitivity and specificity of machine learning classifiers (MLCs) for glaucoma diagnosis using Spectral Domain OCT (SD-OCT) and standard automated perimetry (SAP). METHODS: Observational cross-sectional study. Sixty two glaucoma patients and 48 healthy individuals were included. All patients underwent a complete ophthalmologic examination, achromatic standard automated perimetry (SAP) and retinal nerve fiber layer (RNFL) imaging with SD-OCT (Cirrus HD-OCT; Carl Zeiss Meditec Inc., Dublin, California). Receiver operating characteristic (ROC) curves were obtained for all SD-OCT parameters and global indices of SAP. Subsequently, the following MLCs were tested using parameters from the SD-OCT and SAP: Bagging (BAG), Naive-Bayes (NB), Multilayer Perceptron (MLP), Radial Basis Function (RBF), Random Forest (RAN), Ensemble Selection (ENS), Classification Tree (CTREE), Ada Boost M1(ADA),Support Vector Machine Linear (SVML) and Support Vector Machine Gaussian (SVMG). Areas under the receiver operating characteristic curves (aROC) obtained for isolated SAP and OCT parameters were compared with MLCs using OCT+SAP data. RESULTS: Combining OCT and SAP data, MLCs' aROCs varied from 0.777(CTREE) to 0.946 (RAN).The best OCT+SAP aROC obtained with RAN (0.946) was significantly larger the best single OCT parameter (p<0.05), but was not significantly different from the aROC obtained with the best single SAP parameter (p=0.19). CONCLUSION: Machine learning classifiers trained on OCT and SAP data can successfully discriminate between healthy and glaucomatous eyes. The combination of OCT and SAP measurements improved the diagnostic accuracy compared with OCT data alone.
