CEM : Cultura, Espa?o & Memória , 2011,
Abstract: The Junta Patriótica do Norte (JPN) was created a month after Germany’s declaration of war, stating that one of its purposes would be to follow the conflict. However, its efforts were extended and intensified in the postwar period, particularly with respect to assistance to war orphans, the organization of war commemorations, and last but not least, the dissemination and implementation of artistic tributes to the war’s fallen men. This article intends, besides the organic understanding of the institution, to first explore the Junta’s role in the conflict’s mobilization efforts and, second, its role in how the memory – material and immaterial – of World War I in Portugal has be shaped.

Abstract: Pulmonary colonization of cystic fibrosis (CF) patients with Burkholderia cenocepacia or other bacteria of the Burkholderia cepacia complex (Bcc) is associated with worse prognosis and increased risk of death. During colonization, the bacteria may evolve under the stressing selection pressures exerted in the CF lung, in particular, those resulting from challenges of the host immune defenses, antimicrobial therapy, nutrient availability and oxygen limitation. Understanding the adaptive mechanisms that promote successful colonization and long-term survival of B. cenocepacia in the CF lung is essential for an improved therapeutic outcome of chronic infections. To get mechanistic insights into these adaptive strategies a transcriptomic analysis, based on DNA microarrays, was explored in this study. The genomic expression levels in two clonal variants isolated during long-term colonization of a CF patient who died from the cepacia syndrome were compared. One of the isolates examined, IST439, is the first B. cenocepacia isolate retrieved from the patient and the other isolate, IST4113, was obtained three years later and is more resistant to different classes of antimicrobials. Approximately 1000 genes were found to be differently expressed in the two clonal variants reflecting a marked reprogramming of genomic expression. The up-regulated genes in IST4113 include those involved in translation, iron uptake (in particular, in ornibactin biosynthesis), efflux of drugs and in adhesion to epithelial lung tissue and to mucin. Alterations related with adaptation to the nutritional environment of the CF lung and to an oxygen-limited environment are also suggested to be a key feature of transcriptional reprogramming occurring during long-term colonization, antibiotic therapy and the progression of the disease.

Abstract: objective: to estimate the prevalence of young people's involvement in violence measured as participation in physical fights or being physically, sexually or emotionally abused. we also aimed to understand the role of social, demographic and other behavioural characteristics in violence. methods: we evaluated 7511 adolescents (4243 girls and 3268 boys) aged 15 to 19 years old, enrolled in public schools. information was obtained using an anonymous, self-administrated questionnaire. results: the most frequently reported type of violence was emotional abuse (15.6%). boys reported greater involvement in fights (3.6 vs. 13.6%, p<0.001) and physical abuse (7.5 vs. 19.5%, p<0.001). the prevalence of emotional abuse (16.2 vs. 14.8%, p=0.082) and sexual abuse (2.0 vs. 1.8%, p=0.435) was similar in girls and boys. after adjustment, increasing age decreased the odds of being involved in fights in both genders but increased the odds of emotional abuse. living in a rented home was associated with physical abuse in girls (odds ratio [or]: 1.4; 95% confidence interval [95%ci]: 1.0-1.9) and boys (or: 1.6; 95%ci: 1.2-2.0). in girls the odds of being emotionally abused increased with greater parental education. smoking and cannabis use were associated with all types of violence in both genders. conclusions: the most frequently reported form of violence was emotional abuse. we found differences by gender, with boys reporting more physical abuse and involvement in fights. adolescents whose parents had a higher educational level reported more physical and emotional abuse, which may be related to differences in the perception of abuse.
Compara??o da varia??o de resposta ao broncodilatador através da espirometria em portadores de asma ou doen?a pulmonar obstrutiva cr?nica

Abstract: objective: making the differential diagnosis between asthma and chronic obstructive pulmonary disease (copd) based on the response to inhaled bronchodilators by means of spirometry is controversial. the objective of this study was to identify the most useful spirometric variables in order to distinguish between asthma and copd. methods: retrospective study conducted from april of 2004 to january of 2006, comparing the spirometric parameters of 103 nonsmoking patients with asthma to those of 108 patients with copd who were smokers for more than 10 pack-years. all of the patients included in the study were older than 40 and presented stable disease at the time of the test. results:initial forced expiratory volume in one second (fev1) was the same in the two groups (pre-bronchodilator vef1 = 51%). however, patients with copd were older (66 ± 9 years vs. 59 ± 11 years, p < 0.001) and more frequently male (73 vs. 27%, p < 0,001).after the use of the bronchodilator, the median absolute difference in fev1 was 0.25 l (range, -0.09 to 1.13 l) in patients with asthma and 0.09 l (range, -0.1 to 0.73 l) in those with copd (p < 0.001). the highest sensitivity (55%), specificity (91%) and likelihood ratio (6.1) for asthma diagnosis was obtained when the percentage increase in postbronchodilator fev1 in relation to the predicted fev1 (δ%prevvef1) was equal to or greater than 10%. isolated significant increases in forced vital capacity were more common in patients with copd. conclusions: in patients over the age of 40 and presenting obstructive lung disease, a δ%prevvef1 > 10% is the best spirometric parameter to distinguish asthma from copd.

Abstract: thermophysical properties, density and viscosity of model solutions similar to juices were experimentally determined. the results were compared to those predicted by mathematical models (statistic 6.0) and to values mentioned in the literature, according to the chemical composition. a star planning was adopted to define model solutions composition; fixing the acid amount in 1.5% and varying water (82-98.5%), carbohydrate (0-15%) and fat (0-1.5%). the density was determined by picnometer. the viscosity was determined by brookfield lvf model viscosimeter. the thermal conductivity was calculated based on thermal diffusivity and specific heat values (presented at the 1st . part of this paper - moura [7]) and density. the results of each property were analyzed by the response surface method. the found results were significant, indicating that the models represent the changes of thermal and physical juices properties, according to their composition and temperature variations.
Literacy, Ethnicity and Style  [PDF]

Advances in Anthropology (AA) , 2013, DOI: 10.4236/aa.2013.34A002
Abstract:

I present the result of a two-year research project developed at the “Instituto de Estudos de Linguagem” (IEL/Unicamp, Brazil) and also of action research I have been organizing since 2006 when I started to work as a professor at the “Universidade Federal de Sao Carlos”, in Brazil. Relying on recent developments in New Literacy Studies, I explore the concept of the continuum illiterate-literate and argue that it implies elements of transformation, as well as conservation. I also argue that three intersecting continua must be considered together: the continua oral-written, rural-urban and restricted-full literacy, always taking into consideration ethnicity as a variable (Cohen, 1974). Drawing on ethnographic fieldwork in Brazil, I show how elements of restricted literacy (Goody, 1968) are presented on the threshold of the twenty first century; how they entertain relation with the rural to urban migration and with a marked contrast between different ethnicities; and in what sense this fact may be visible in the everyday use of language and in the style inherent in it.

Nheengatu Language and Its Role in the Tactics of Construction of Indigenous Identity  [PDF]
Maria Sílvia Cintra
Advances in Anthropology (AA) , 2018, DOI: 10.4236/aa.2018.84012
Abstract: Nheengatu is one of the co-official languages of São Gabriel da Cachoeira in the Amazon region (AM/Brazil). About 8000 people in the Upper Rio Negro region speak it, and there exists a contemporary movement for its revitalization in the state of Pará (PA/Brazil). Based upon field research in both these regions, this paper bears reflections on the inter-relations existing between language and identity including references in the areas of Applied Linguistics, Culture Semiotics and Anthropology. I propose a discussion on Nheengatu language, which is often considered in a dysphoric way, i.e., as if it had been imposed on the natives, resulting only from the colonizers’ strategies. I propose we can instead envisage it from the perspective concerning the tactics constructed by the aboriginals in order to preserve and reconquer their identity, i.e., from the point of view of a Poetics of Relation within a complex, contradictory and hybrid linguistic approach.
