O uso de textos polêmicos em sala de aula: formação e prática docente

The purpose of this article is twofold. First, it examines how Discourses, socially accepted ways of speaking, listening, writing, and reading that illustrate individuals' memberships in specific social groups (Gee, 2008), could influence teachers' use or censorship of polemic text in the classroom. Second, this article presents a review of the research literature about teachers' inclusion of culturally diverse themes in their classrooms. For example, it describes professors' use of children´s books about racism with new teachers. It also outlines suggestions for guiding discussions that respect students' heritage, build critical literacy, and support culturally responsive teaching pedagogies.

Culturally-sensitive complaints of depressions and anxieties in women

Background: Current classifications of Mental Disorders are centered on Westernized concepts and constructs. Cross-cultural sensitivity emphasizes culturally-appropriate translations of symptoms and questions, assuming that concepts and constructs are applicable.Methods: Groups and individual psychiatrists from various cultures from Asia, Latin America, North Africa and Eastern Europe prepared descriptions of main symptoms and complaints of treatment-seeking women in their cultures, which are interpreted by clinicians as a manifestation of a clinically-relevant dysphoric disorder. They also transliterated the expressions of DSM IV criteria of main dysphoric disorders in their cultures.Results: In many non-western cultures the symptoms and constructs that are interpreted and treated as dysphoric disorders are mostly somatic and are different from the Western-centered DSM or ICD systems. In many cases the DSM and ICD criteria of depression and anxieties are not even acknowledged by patients.Limitations: the descriptive approach reported here is a preliminary step which involved local but Westernized clinicians-investigators following a biomedical thinking. It should be followed by a more systematic-comprehensive surveys in each culture.Conclusions: Westernized concepts and constructs of mental order and disorders are not necessarily universally applicable. Culturallysensitive phenomena, treatments and treatment responses may be diversified. Attempts at their cross-cultural harmonization should take into consideration complex interactional multi-dimensional processes. (c) 2006 Elsevier B.V. All rights reserved.

Prediction of occurrences of diverse chemical classes in the Asteraceae through artificial neural networks

The training and the application of a neural network system for the prediction of occurrences of secondary metabolites belonging to diverse chemical classes in the Asteraceae is described. From a database containing about 604 genera and 28,000 occurrences of secondary metabolites in the plant family, information was collected encompassing nine chemical classes and their respective occurrences for training of a multi-layer net using the back-propagation algorithm. The net supplied as output the presence or absence of the chemical classes as well as the number of compounds isolated from each taxon. The results provided by the net from the presence or absence of a chemical class showed a 89% hit rate; by excluding triterpenes from the analysis, only 5% of the genera studied exhibited errors greater than 10%.

Repetition of Suicide Attempts Data from Emergency Care Settings in Five Culturally Different Low- and Middle-Income Countries Participating in the WHO SUPRE-MISS Study

Background: Attempted suicide is a strong risk factor for subsequent suicidal behaviors. Innovative strategies to deal with people who have attempted suicide are needed, particularly in resource-poor settings. Aims: To evaluate a brief educational intervention and periodic follow-up contacts (BIC) for suicide attempters in five culturally different sites (Campinas, Brazil; Chennai, India; Colombo, Sri Lanka; Karaj, Islamic Republic of Iran; and Yuncheng, People's Republic of China) as part of the WHO Multisite Intervention Study on Suicidal Behaviors (SUPRE-MISS). Methods: Among the 1,867 suicide attempters enrolled in the emergency departments of the participating sites, 922 (49.4%) were randomly assigned to a brief intervention and contact (BIC) group and 945 (50.6%) to a treatment as usual (TAU) group. Repeated suicide attempts over the 18 months following the index attempt - the secondary outcome measure presented in this paper - were identified by follow-up calls or visits. Subsequent completed suicide - the primary outcome measure has been reported in a previous paper. Results: Overall, the proportion of subjects with repeated suicide attempts was similar in the BIC and TAU groups (7.6% vs. 7.5%, chi(2) = 0.013; p = .909), but there were differences in rates across the five sites. Conclusions: This study from five low-and middle-income countries does not confirm the effectiveness of brief educational intervention and follow-up contacts for suicide attempters in reducing subsequent repetition of suicide attempts up to 18 months after discharge from emergency departments.

Diverse Amorphous Carbonaceous Thin Films Obtained by Plasma Enhanced Chemical Vapor Deposition and Plasma Immersion Ion Implantation and Deposition

Diverse amorphous hydrogenated carbon and similar films containing additional elements were produced by Plasma Enhanced Chemical Vapor Deposition (PECVD) and by Plasma Immersion Ion Implantation and Deposition (PIIID). Thus a-C:H, a-C:H:F, a-C:H:N, a-C:H:Cl and a-C:H:O:Si were obtained, starting from the same feed gases, using both techniques. The same deposition system supplied with radiofrequency (RF) power was used to produce all the films. A cylindrical stainless steel chamber equipped with circular electrodes mounted horizontally was employed. RF power was fed to the upper electrode; substrates were placed on the lower electrode. For PIIID negative high tension pulses were also applied to the lower electrode. Raman spectroscopy confirmed that all the films are amorphous. Chemical characterization of each pair of films was undertaken using Infrared Reflection Absorption Spectroscopy and X-ray Photoelectron Spectroscopy. The former revealed the presence of specific structures, such as C-H, C-O, O-H. The latter allowed calculation of the ratio of hetero-atoms to carbon atoms in the films, e. g. F:C, N:C, and Si:C. Only relatively small differences in elemental composition were detected between films produced by the two methods. The deposition rate in PIIID is generally reduced in relation to that of PECVD; for a-C:H:Cl films the reduction factor is almost four.

Environmental diagnosis in areas with different use and occupation using the perception of diverse biological activity

In Brazil, the degradation of soil and landscape by urban and agricultural frontiers expansion leads to the need for comprehensive studies and consider the diverse biological activities generated from different interventions in the landscape, becoming an instrument for assessing the impacts and the decision for its environmental management. The objective of this study was to evaluate the influence of different forms of occupation of the landscape, considering ecological elements and their interactions. The work was carried out on the Instituto Agronômico in the county of Jundiai, in the state of Sao Paulo, Brazil. The area under study has been subjected to different use and occupancy for a period of about 40 years. During this period the landscape has been transformed, with the current scenario can be classified as a degraded area mining; grassy area; Araucaria forest and pasture. These areas were evaluated by means of a transect, from which ten sampling sites were selected for the description of diverse biological activities, which included: evaluation and description of ground cover, identifying the presence of fungus and insect species. Furthermore, we evaluated in these points the pH, fertility and porosity of the topsoil (0-0.10 m). The results showed a variation of the elements analyzed and a relationship between the use and occupation of land in the different scenarios of the current landscape. The biological activity was more diverse in the Araucaria forest, reflected by the abundance of litter, higher content of organic matter and soil nutrients, demonstrating the effectiveness of the technique for assessing the level of degradation of the landscape used, which is expeditious and inexpensive.

Detection of chromosomal bla(CTX-M-2) in diverse Escherichia coli isolates from healthy broiler chickens

The rise of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in food-producing animals is a growing concern for public health. We investigated ESBL producers isolated from broiler chickens in Brazil and characterized 19 CTX-M-2-producing E.coli. The ISCR1 was detected upstream of the chromosome-located gene bla(CTX-M-2), associated with sul-1 type integron structure. CTX-M-2-producing E.coli exhibited different PFGE-types and phylogenetic groups, showing a non-clonal dissemination. The sequence types found (ST93, ST155 and ST2309) have been associated with humans and animals worldwide. Herein, we report the chromosomal location of bla(CTX-M-2) on E.coli, highlighting the risks of multidrug-resistant bacteria in food-producing animals.

Diverse urban plantings managed with sufficient resource availability can increase plant productivity and arthropod diversity

Buildings structures and surfaces are explicitly being used to grow plants, and these "urban plantings" are generally designed for aesthetic value. Urban plantings also have the potential to contribute significant "ecological values" by increasing urban habitat for animals such as arthropods and by increasing plant productivity. In this study, we evaluated how the provision of these additional ecological values is affected by plant species richness; the availability of essential resources for plants, such as water, light, space; and soil characteristics. We sampled 33 plantings located on the exterior of three buildings in the urban center of Brisbane, Australia (subtropical climatic region) over 2, 6 week sampling periods characterized by different temperature and rainfall conditions. Plant cover was estimated as a surrogate for productivity as destructive sampling of biomass was not possible. We measured weekly light levels (photosynthetically active radiation), plant CO2 assimilation, soil CO2 efflux, and arthropod diversity. Differences in plant cover were best explained by a three-way interaction of plant species richness, management water regime and sampling period. As the richness of plant species increased in a planter, productivity and total arthropod richness also increased significantly likely due to greater habitat heterogeneity and quality. Overall we found urban plantings can provide additional ecological values if essential resources are maintained within a planter such as water, light and soil temperature. Diverse urban plantings that are managed with these principles in mind can contribute to the attraction of diverse arthropod communities, and lead to increased plant productivity within a dense urban context.

O uso do rádio e da TV por instituições religiosas: um fenômeno crescente nos mais variados canais de comunicação

In the present study aimed to study the use of radio and television in Brazil by the various Christian aspects rooted in the country. The main objective was to analyze how the churches define the orientation or the use of strategies of both comprehensive and traditional media vehicles, which are still the most popular mass media, both for the formation of culture and national public opinion in both states and municipalities, which demarcate and retain regional traits that differentiate culturally, economically and socially diverse Brazilian populations. Christian churches are increasingly seeking loopholes and legal facilities, public spaces and broadcast media to facilitate the achievement of followers of their theological ideologies. On the radio, on television and also through social networks of the Internet, pastors, priests, bishops and lay Christians to seek their potential both in public space and home individually, using old and new individual devices and portable reception of audiovisual content. All preachers fiercely competing for space leased the open television networks, in national and local radio stations and invest in the organization of broadcasters Community legalized or informal. The work also aims to study the radio and television concessions in Bauru, to show the failures that occur in broadcasting spectrum management by the federal government and also for the reader to understand what the Constitution says about the use of these vehicles public concession by religious institutions
