Esta pesquisa teve como pano de fundo a história, as legislações e ações de âmbito nacional referentes ao tema das relações étnico-raciais. O foco central de estudo foram as práticas educativas de professores da Educação Básica, especificamente na realidade sócio-educacional de escolas públicas da rede municipal de ensino da cidade de São Bernardo do Campo. Para isso, à luz da lei 10.639/2003 que alterou a Lei de Diretrizes e Bases da Educação Nacional e incluiu a história e cultura afrobrasileira no currículo oficial de ensino, analisou-se o que justificou o desenvolvimento de projetos pedagógicos sobre essa temática por aproximadamente 400 professores nos anos de 2008 e 2009, período em que não havia investimentos significativos da Secretaria de Educação no que se refere ao tema. A partir de uma abordagem qualitativa de natureza interpretativa, foram aplicados questionários aos professores, para saber o que motivou a realização dos projetos e o papel da formação nesse contexto. Analisou-se, ainda, como as práticas docentes têm contribuído para a discussão do papel da escola (problematizadora /reprodutora) em relação à implementação da Lei 10639/03. A pesquisa constatou que os processos de formação em suas diferentes modalidades podem ser um importante disparador para o desenvolvimento de trabalhos significativos sobre a temática das relações étnico-raciais. Evidenciou, ainda, a importância das leis mencionadas, se não para resolver a questão da invisibilidade da história da África e suas contribuições para a história e cultura brasileira, para contribuir também na problematização das relações raciais e apontar novos caminhos para redução das grandes diferenças sociais existentes no interior das escolas brasileiras.

The research project examines representations elaborated about Amelia Duarte Machado, images that were built in a particular space: the Natal City. Amelia, one mossoroense that has a simple life, stated a luxurious life after marrying with a rich Portuguese merchant Manuel Machado, in 1904. She led a life of society lady, lived in a sumptuous residence, traveled to Europe, attending the Theatre the city and took care of the social image of her husband, opening the doors of your home to promote dinners and receptions. Experienced the changes occurring in Natal in the first three decades of the twentieth century, when the initiative of a political and intellectual elite of the city began to incorporate bourgeois values and to provide a technical framework focused on the improvements brought by the Industrial Revolution. In 1934, with her husband's death, took over the family business. Besides the widow, also became an enterprising woman. The widow Amelia Machado also became the target of suspicion of the population, rumors about his life. From there emerges a frightening figure in Natal, a being that captured and ate the liver of children, the papa-figo of Natal City, the Widow Machado. In this research, we relate different images that circulated about this woman, who was society lady, dashing widow and papa-figo, articulating these representations with the discourse on female circulating in Natal from 1900 to 1930 yet will raise hypotheses about the creation of the Legend of the Widow Machado

A dissertação preocupou-se em analisar as relações de bandidos e ex-bandidos com o pentecostalismo na Assembleia de Deus Fortificada em Cristo (ADFEC), situada na favela Jardim São Jorge, periferia da Cidade Ademar, região Sul da capital de São Paulo. Interessou-nos compreender as interações desses agentes e de qual maneira a igreja desempenhou seu trabalho em um espaço pentecostal. A pesquisa, teve como objetivo fundamental, examinar as aproximações da criminalidade e o pentecostalismo indicando suas rupturas e características peculiares. O trabalho de campo se dedicou em coletar dados que comprovassem atuação da ADFEC juntos aos agentes do crime, e em que medida a filiação religiosa dos agentes ganhava importância. Por fim, buscamos refletir sobre a adesão de bandidos e ex-bandidos ao pentecostalismo e a influência dessa adesão no cotidiano da comunidade.

David Hume belonged to the consecuencialist philosophical tendency, in which is included utilitarianism. This tendency was opposed to the normativism philosophy, in which is enrolled contractualism. This article analyzes the critique made by David Hume, from the utilitarianism perspective, against contractualism. The major philosophers of contractualism are Thomas Hobbes, John Locke and Jean Jacques Rousseau. Hume implemented three arguments in opposition to them: 1) historic: the social contract does not have any practical testing. Therefore it could not be presented as the foundation of the state; 2) philosophical: it is not the duty, but the interest that moves men to seek the formation of the political authority; 3) social: in the consciousness of the people, there is no trace of the social contract.Utilitarianism was one of the philosophical tendencies that finished the theoretical hegemony that contractualism had during the XVII and the XVIII centuries. Nonetheless from the historical and social point of view, the liberalization movements in many parts of the world, at that time, were inspired by contractualism. It means that from the theoretical point of view, utilitarianism, certainly, stressed the empirical origins of the state but not the rational justification of the political Authority. Hume was unable to understand the normative force that contractualism owns, which inspires human action.

OBJECTIVES: Develop recommendations for women's health issues and family planning in systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS). METHODS: Systematic review of evidence followed by modified Delphi method to compile questions, elicit expert opinions and reach consensus. RESULTS: Family planning should be discussed as early as possible after diagnosis. Most women can have successful pregnancies and measures can be taken to reduce the risks of adverse maternal or fetal outcomes. Risk stratification includes disease activity, autoantibody profile, previous vascular and pregnancy morbidity, hypertension and the use of drugs (emphasis on benefits from hydroxychloroquine and antiplatelets/anticoagulants). Hormonal contraception and menopause replacement therapy can be used in patients with stable/inactive disease and low risk of thrombosis. Fertility preservation with gonadotropin-releasing hormone analogues should be considered prior to the use of alkylating agents. Assisted reproduction techniques can be safely used in patients with stable/inactive disease; patients with positive antiphospholipid antibodies/APS should receive anticoagulation and/or low-dose aspirin. Assessment of disease activity, renal function and serological markers is important for diagnosing disease flares and monitoring for obstetrical adverse outcomes. Fetal monitoring includes Doppler ultrasonography and fetal biometry, particularly in the third trimester, to screen for placental insufficiency and small for gestational age fetuses. Screening for gynaecological malignancies is similar to the general population, with increased vigilance for cervical premalignant lesions if exposed to immunosuppressive drugs. Human papillomavirus immunisation can be used in women with stable/inactive disease. CONCLUSIONS: Recommendations for women's health issues in SLE and/or APS were developed using an evidence-based approach followed by expert consensus.

Questa tesi si propone di fare luce sulla figura e sulle idee di Aleksandra Michajlovna Kollontaj (San Pietroburgo 1987 – Mosca 1952), attivista per i diritti delle donne, bolscevica e membro del partito comunista sovietico, nel quadro della storia dell’Unione Sovietica dal 1917 all’inizio degli anni ’30 del Novecento. Verrà presentato l’articolo "Novaja ženščina", in cui l’autrice delinea un modello per tutte le future cittadine sovietiche: la cosiddetta 'donna nuova', che rifiuta la 'schiavitù' del ruolo esclusivo di madre e moglie e afferma la propria libertà attraverso il lavoro e l’impegno sociale Si riprenderanno le vicende del romanzo della Kollontaj "Vasilisa Malygina". L’eroina che dà il titolo all’opera è la trasposizione letteraria della donna nuova e rappresenta le contraddizioni di una 'creatura di transizione' fra l’epoca prerivoluzionaria e quella sovietica. In seguito verranno messe il luce le contraddizioni nelle proposte della Kollontaj. Per ultimo verrà delineato un quadro delle libertà civili introdotte nella Russia degli anni ’20 e il successivo ritorno, con la salita al potere di Stalin, alla repressione delle libertà e a un rigido controllo statale su tutti gli ambiti della vita. Si sottolineerà come il corso della storia non permise alle idee proposte dalla Kollontaj di affermarsi nella quotidianità della vita sovietica.

Studies on hacking have typically focused on motivational aspects and general personality traits of the individuals who engage in hacking; little systematic research has been conducted on predispositions that may be associated not only with the choice to pursue a hacking career but also with performance in either naïve or expert populations. Here, we test the hypotheses that two traits that are typically enhanced in autism spectrum disorders—attention to detail and systemizing—may be positively related to both the choice of pursuing a career in information security and skilled performance in a prototypical hacking task (i.e., crypto-analysis or code-breaking). A group of naïve participants and of ethical hackers completed the Autism Spectrum Quotient, including an attention to detail scale, and the Systemizing Quotient (Baron-Cohen et al., 2001, 2003). They were also tested with behavioral tasks involving code-breaking and a control task involving security X-ray image interpretation. Hackers reported significantly higher systemizing and attention to detail than non-hackers. We found a positive relation between self-reported systemizing (but not attention to detail) and code-breaking skills in both hackers and non-hackers, whereas attention to detail (but not systemizing) was related with performance in the X-ray screening task in both groups, as previously reported with naïve participants (Rusconi et al., 2015). We discuss the theoretical and translational implications of our findings.

This study aimed to describe the spatial and temporal patterns of variation in trophic state and its relation with the structure and dynamics of planktonic community of a large reservoir located in semi-arid tropical region of Northeast Brazil. The reservoir Armando Ribeiro Gonçalves is the biggest reservoir of the Rio Grande do Norte State and is responsible for about 53% of all surface water accumulated in the State. The samples of water and plankton were taken monthly in 10 points distributed throughout the longitudinal axis of the reservoir and over a full hydrological cycle. The samples were collected to determine concentrations of total phosphorus, total nitrogen, chlorophyll a and suspended solids (fixed and volatile) and for determining the composition and abundance of phytoplanktonic and zooplanktonic species. During the study period, the reservoir was characterized as eutrophic and there was no trend of increasing the trophic state of the reservoir in the period of drought. The concentrations of total phosphorus and suspended fixed solids decreased towards the dam while the N:P ratios increased in the same direction due to the reduction in the phosphorus concentrations and relative constancy in the nitrogen concentrations. The N:P ratios observed were indicative of greater limitation by phosphorus than by nitrogen. However, as concentrations of both nutrients were high and the water transparency was very low, with secchi depth usually lower than one meter, it seems likely that the planktonic primary production of the reservoir is more limited by the availability of light than the availability of nutrients. High nutrient concentrations coupled with low availability of light may explain the continuing dominance of filamentous cyanobacteria such as Cylindrospermopsis raciborskii in the plankton of the reservoir.These cyanobacteria are potentially toxic and pose a serious environmental problem because it compromises the water quality for public supply, recreation and fishing when present in high densities as in this study. The mesozooplankton of the reservoir was dominated by the calanoid Notodiaptomus cearensis and the cladoceran Diaphanosoma spinulosum. In general, the structure of zooplankton community seems to be particularly influenced by the spatial variation of cyanobacteria. The results of the regression analyses show that both the chlorophyll a concentrations and the cyanobacteria biovolume were more strongly correlated with the nitrogen than with phosphorus and that the water transparency was more strongly correlated with algal biomass than with other sources of turbidity. The maximum load of phosphorus to attain the maximum permissible concentration of total P in the reservoir was estimated in 63.2 tonnes P/ year. The current external P load to the reservoir is estimated in 324 tonnes P / year and must be severely reduced to improve the water quality for water supply and allow the implementation of aquaculture projects that could contribute to the socio-economic development of the region

A proteinaceous trypsin inhibitor was purified from Crotalaria pallida seeds by ammonium sulphate fractionation, affinity chromatography on immobilized Trypsin-Sepharose and TCA precipitation. The trypsin inhibitor, named ITC, had Mr of 32.5 kDa by SDS-PAGE and was composed by two subunits with 27.7 and 5.6 kDa linked by disulphide bridges, a typical characteristic of Kunitz-Inhibitor family. ITC was stable until 50°C, and at 100°C its residual activity was of about 60%. Also, ITC was stable at pHs 2 to 12. The inhibition of trypsin by ITC was non-competitive, with a Ki of 8,8 x 10-7M. ITC inhibits weakly other serine proteinases such as chymotrypsin and elastase. The inhibition of papain (44% of inhibition), a cysteine proteinase was an indicative of the bi-functionality of ITC. In vitro assays against digestive proteinases from several Lepdoptera, Diptera and Coleoptera pests were made. ITC inhibited in 100% digestive enzymes of Ceratitis capitata (fruit fly), Spodoptera frugiperda and Alabama argillacea, the last one being a cotton pest. It also inhibited in 74.4% Callosobruchus maculatus (bean weevil) digestive enzymes, a Coleoptera pest. ITC, when added in artificial diet models, affected weakly the development of C. capitata larvae and it had a WD50 of 2.65% to C. maculatus larvae

The fruit fly Ceratitis capitata is considered the most destructive pest of the world fruitculture. Many pest management practices, mainly based on agrochemicals, have been developed to allow the world-wide commerce of fruit. Solutions to decrease the use of synthetic insecticides in agriculture are based on the development of new target-specific compounds which cause less damage to the environment, especially vegetal proteins with insecticidal effects. The aim of this work was to evaluate the deleterious effect of a purified vicilin of E. velutina (EvV) seeds to C. capitata larvae and adult insects and to investigate the mechanisms involved in these effects. EvV was purified, characterized and its deleterious effect was tested in bioassay systems. EvV mechanism of action was determined by immunodetection techniques and fluorescence localization in chitin structures that are present in C. capitata digestory system. EvV is a glycoprotein with affinity to chitin. Its molecular weight, of 216,57 kDa, was determined by gel filtration chromatography in FPLC system. Using SDS-PAGE, it was possible to observe EvV dissociation in two main subunits of 54,8 and 50,8 kDa. When it was submitted to eletrophoresis in native conditions, EvV presented only one band of acid characteristic. The WD50 and LD50 values found in the bioassays were 0,13% and 0,14% (w/w), respectively for the larvae. EvV deleterious effects were related to the binding to chitin structures presented in peritrophic membrane and gut epithelial cells, associated with its low digestibility in C. capitata digestive tract. The results described herein are the first demonstration of the larvicidal effects of plant protein on C. capitata larvae. EvV may be part of the pest management programs, in the toxic bait composition, or an alternative in plant improvement program

This review will make familiar with new concepts in ovarian cancer and their impact on radiological practice. Disseminated peritoneal spread and ascites are typical of the most common (70–80 %) cancer type, highgrade serous ovarian cancer. Other cancer subtypes differ in origin, precursors, and imaging features. Expert sonography allows excellent risk assessment in adnexal masses. Owing to its high specificity, complementary MRI improves characterization of indeterminate lesions. Major changes in the new FIGO staging classification include fusion of fallopian tube and primary ovarian cancer and the subcategory stage IIIA1 for retroperitoneal lymph node metastases only. Inguinal lymph nodes, cardiophrenic lymph nodes, and umbilical metastases are classified as distant metastases (stage IVB). In multidisciplinary conferences (MDC), CT has been used to predict the success of cytoreductive surgery. Resectability criteria have to be specified and agreed on in MDC. Limitations in detection of metastases may be overcome using advanced MRI techniques.

Background Both primary and secondary gynaecological neuroendocrine (NE) tumours are uncommon, and the literature is scarce concerning their imaging features. Methods This article reviews the epidemiological, clinical and imaging features with pathological correlation of gynaecological NE tumours. Results The clinical features of gynaecological NE tumours are non-specific and depend on the organ of origin and on the extension and aggressiveness of the disease. The imaging approach to these tumours is similar to that for other histological types and the Revised International Federation of Gynecology and Obstetrics (FIGO) Staging System also applies to NE tumours. Neuroendocrine tumours were recently divided into two groups: poorly differentiated neuroendocrine carcinomas (NECs) and well-differentiated neuroendocrine tumours (NETs). NECs include small cell carcinoma and large cell neuroendocrine carcinoma, while NETs account for typical and atypical carcinoids. Cervical small cell carcinoma and ovarian carcinoid are the most common gynaecological NE tumours. The former typically behaves aggressively; the latter usually behaves in a benign fashion and tends to be confined to the organ. Conclusion While dealing with ovarian carcinoids, extraovarian extension, bilaterality and multinodularity raise the suspicion of metastatic disease. NE tumours of the endometrium and other gynaecological locations are very rare. Teaching Points • Primary or secondary neurondocrine (NE) tumours of the female genital tract are rare. • Cervical small cell carcinoma and ovarian carcinoids are the most common gynaecological NE tumours. • Cervical small cell carcinomas usually behave aggressively. • Ovarian carcinoids tend to behave in a benign fashion. • The imaging approach to gynaecological NE tumours and other histological types is similar.

Objectives To review the epidemiological and clinical features of primary fallopian tube carcinoma (PFTC), and to illustrate the spectrum of MRI findings, with pathological confirmation. Methods This article reviews the relevant literature on the epidemiological, clinical, and imaging features of primary fallopian tube carcinoma, with pathological confirmation, using illustrations from the authors’ teaching files. Results Primary fallopian tube carcinoma came under focus over the last few years due to its possible role on the pathogenesis of high-grade serous epithelial ovarian and peritoneal cancers. Typical symptoms, together with the presence of some of the most characteristic MRI signs, such as a Bsausage-shaped^ pelvic mass, hydrosalpinx, and hydrometra, may signal the presence of primary fallopian cancer, and allow the radiologist to report it as a differential diagnosis. Conclusions Primary fallopian tube carcinoma has a constellation of clinical symptoms and magnetic resonance imaging features, which may be diagnostic. Although these findings are not present together in the majority of cases, radiologists who are aware of them may include the diagnosis of primary fallopian tube cancer in their report more frequently and with more confidence. Teaching Points • PFTC may be more frequent than previously thought • PFTC has specific clinical and MRI characteristics • Knowledge of typical PFTC signs enables its inclusion in the differential diagnosis • PFTC is currently staged under the 2013 FIGO system • PFTC is staged collectively with ovarian and peritoneal neoplasms
