Escolha, seleção e segregação nas escolas municipais do Rio de Janeiro

O artigo investiga a distribuição e o acesso a vagas em escolas municipais da cidade do Rio de Janeiro com foco na oferta escolar. Sistematiza uma bibliografia sobre regras de matrícula/escolha em redes escolares de diferentes países. A análise é centrada em dois polos de matrícula heterogêneos com grande fluxo de alunos entre o primeiro e o segundo segmentos do ensino fundamental. As análises ilustram o padrão do fluxo entre as escolas e identificam os procedimentos e as justificativas utilizados pela direção das escolas na seleção e na distribuição de alunos. Os resultados mostram padrões não aleatórios de distribuição de alunos e a ocorrência de ações veladas dos atores que indicam brechas nas regras de matrícula e que contribuem para a segregação escolar no município.

Casa, rua, escola: gênero e escolarização em setores populares urbanos

Este artigo deriva de pesquisa que buscou compreender o papel da socialização familiar na construção de trajetórias escolares diferenciadas por sexo, a partir do olhar de 25 crianças de camadas populares de uma escola municipal de São Paulo. Por meio de observações e entrevistas, obtiveram-se informações sobre a participação de meninas e meninos nos afazeres domésticos, nas práticas de lazer e na circulação pelo espaço público. Conclui-se que a socialização familiar tende a estimular um desempenho superior das meninas tanto pela construção de feminilidades pautadas por responsabilidade e disciplina, quanto pela significação positiva da escola enquanto um espaço de recreação e sociabilidade, em face das inúmeras restrições que as garotas sofrem no seu cotidiano na família, na casa e na rua.

Levantamento dos temas TIC e EAD na biblioteca virtual Educ@

Trata-se de uma pesquisa que envolveu a exploração dos 36 periódicos que compõem o repositório Educ@ com vistas ao levantamento das publicações que enfocam os temas educação a distância - EAD - e tecnologias da informação e da comunicação - TIC. Excluídos três periódicos que se voltam exclusivamente para a divulgação de estudos relacionados aos temas desse levantamento, foram evidenciados 824 artigos. Os dados tabulados permitiram identificar uma mudança no foco dos estudos encontrados, que discutiam a informática educativa e passaram a investigar o uso/apropriação das TIC e a formação de professores para e por meio da EAD. A partir de 2008, a quantidade de artigos publicados por ano em cada periódico triplicou, sinalizando um aumento do interesse dos pesquisadores por investigações sobre os temas explorados.

The PEDRO (Pocketable Electronic Devices in Radiation Oncology) project: how clinical practice is changing among young radiation oncologists.

Purpose. To evaluate the impact of mobile devices and apps on the daily clinical activity of young radiation oncologists. Methods. A web-based questionnaire was sent to 382 young (≤40 years) members of the Italian Association of Radiation Oncology (AIRO). The 14 items investigated the diffusion of mobile devices (smartphones and/or tablets), their impact on daily clinical activity, and possible differences perceived by the participants over time. Results. A total of 158 questionnaires were available for statistical evaluation (response rate 41%). Up to 75% of respondents declared they used an electronic device during their clinical activity. Conversely, 82% considered the impact of smartphones/tables on daily practice low to moderate. Daily device use increased significantly from 2009 to 2012, with high daily use rates rising from 5% to 39.9%. Fulfillment of professional needs was declared by less than 42% of respondents and compliance with app indications by 32%. Almost all physicians desired in 2012 a comprehensive website concerning a variety of apps covering radiation oncologists' needs. Conclusions. Mobile devices are widely used by young Italian radiation oncologists in their daily clinical practice, while the indications so obtained are not always followed. Nevertheless, it would be important to verify the consistency of information found within apps, in order to avoid potential errors that might be detrimental to patients.

The Beck Cognitive Insight Scale in outpatients with psychotic disorders: further evidence from a French-speaking sample.

OBJECTIVE: The Beck Cognitive Insight Scale (BCIS) evaluates patients' self-report of their ability to detect and correct misinterpretation. Our study aims to confirm the factor structure and the convergent validity of the original scale in a French-speaking environment. METHOD: Outpatients (n = 158) suffering from schizophrenia or schizoaffective disorders fulfilled the BCIS. The 51 patients in Montpellier were equally assessed with the Positive and Negative Syndrome Scale (PANSS) by a psychiatrist who was blind of the BCIS scores. RESULTS: The fit indices of the confirmatory factor analysis validated the 2-factor solution reported by the developers of the scale with inpatients, and in another study with middle-aged and older outpatients. The BCIS composite index was significantly negatively correlated with the clinical insight item of the PANSS. CONCLUSIONS: The French translation of the BCIS appears to have acceptable psychometric properties and gives additional support to the scale, as well as cross-cultural validity for its use with outpatients suffering from schizophrenia or schizoaffective disorders. The correlation between clinical and composite index of cognitive insight underlines the multidimensional nature of clinical insight. Cognitive insight does not recover clinical insight but is a potential target for developing psychological treatments that will improve clinical insight.

Pieces of Iowa’s Past, February 6, 2013

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. THIS WEEK: Women’s and Children’s Building BACKGROUND: 35TH IOWA GENERAL ASSEMBLY The Thirty-fifth General Assembly convened January 13 and adjourned April 19, 1913—a 97-day session. Edward Cunningham was Speaker of the House and William Harding was the Lieutenant Governor presiding over the Senate. The Senate had 18 Democratic members and 32 Republican members. The House of Representatives had 66 Republican members and 42 Democratic members. There were a total of 158 members in the General Assembly. Governor Beryl Carroll finished his term in January 1913 and Governor George Clarke was sworn in on January 16, 1913. He was 60 years old. The 1910 federal census showed Iowa’s population at 2,224,771.

Effects of high-intensity exercises on 13C-nandrolone excretion in trained athletes.

OBJECTIVE: Nandrolone is an anabolic steroid widely used in several sports. The numerous nandrolone positive cases in the recent years (International Olympic Committee statistics) led to several studies in the antidoping field. Nevertheless, essential questions pertaining to nandrolone endogenous production, the effects of physical exercise on the excretion of nandrolone metabolites, and contamination from nutritional supplements must still be addressed. The purpose of this study was to evaluate the influence of exhaustive exercises on 19-norandrosterone (19-NA) and 19-noretiocholanolone (19-NE) urinary excretion rates after administration of labeled nandrolone. SETTING AND PARTICIPANTS: A total of 34 healthy male Caucasian volunteers from the Institute of Sports Sciences and Physical Education (University of Lausanne) applied to participate in the study. All subjects were free from any physical drug addiction and were instructed strictly to avoid any nutritional supplement or steroid before and during the study. The participants were randomly dispatched in 2 groups in a double-blind way: a placebo group and a group treated with C-labeled nandrolone. MAIN OUTCOME MEASUREMENTS: The urinary concentrations of the 2 main nandrolone metabolites, 19-NA and 19-NE, were measured using gas chromatography coupled with mass spectrometry. In addition, clinical parameters such as creatinine, total protein, and beta2-microglobuline levels were determined using immunologic assays. RESULTS: After an oral ingestion of a 25 mg 3,4-C2-nandrolone dose, followed by a second identical dose 24 hours later, 19-NA and 19-NE could be detected in the urine for a period of 6 days after the initial intake. Despite several interesting observations, the measurements were very scattered and did not appear to be significantly influenced by exercise sessions in the athlete population. CONCLUSIONS: The results of this study suggest that physical exercise cannot be considered as a reliable parameter that systematically affects nandrolone metabolite concentrations in the urine.

Nouveautés dans l'immunothérapie du cancer [New developments in cancer immunotherapy]

Les progrès récents dans l'élucidation des bases cellulaires et moléculaires de la réponse immunitaire permettent désormais le design de thérapies novatrices pour l'immunothérapie des tumeurs. Ces approches récentes se traduisent en des taux de réponse qui surpassent souvent ce qui peut être obtenu par des chimiothérapies conventionnelles ou des thérapies ciblées. Nous présentons ici les principaux développements en cours avec un accent sur l'expérience lausannoise dans le traitement du mélanome. Premièrement, les nouveaux développements dans la vaccination peptidique sont présentés. Deuxièmement, les approches de type transfert adoptif sont illustrées avec une attention particulière pour le conditionnement du patient par lymphodéplétion. Finalement, le projet lausannois d'optimisation rationnelle du récepteur TCR des lymphocytes est décrit. Recent progress unveiling the cellular and molecular basis of the immune response allows nowadays the design of novel therapies for tumor immunotherapy. These recent approaches translate into response rates that often surpass what can be obtained by conventional chemotherapies or targeted therapies.
