A Lei 10.639/03 e sua aplica??o na amplia??o da jornada escolar

O presente trabalho tem como inten??o verificar atrav?s de uma pesquisa de campo como se d? o cumprimento da Lei 10.639/03, que estabelece em car?ter obrigat?rio, o ensino da Hist?ria da ?frica e da Cultura Afro-Brasileira no sistema de ensino formal brasileiro, especificamente, na amplia??o da jornada escolar. Para que o trabalho pudesse ser realizado, buscamos na primeira parte, retomar a trajet?ria do Movimento Negro e sua luta pelo direito ? inclus?o da popula??o negra no sistema de ensino brasileiro, incluindo nesta abordagem a necessidade de implanta??o das a??es afirmativas no Brasil, a quest?o da democracia racial e o direito estabelecido pelo programa de cotas. Na segunda fase da pesquisa, nosso exerc?cio foi o de observar a concep??o de educa??o integral proposta pela filosofia pragm?tica, buscando perceber como a escola brasileira se comportou diante da influ?ncia do movimento da Escola Nova, e qual a proposta de educa??o integral ? apresentada pelo programa Mais Educa??o. Na terceira e ?ltima etapa, verificamos como a Hist?ria da ?frica e a Cultura Afro-Brasileira ? abordada no Manual Operacional de Educa??o Integral, que baliza os conte?dos a serem trabalhados na amplia??o da jornada escolar, e relatamos o estudo de caso que buscou descobrir se a Lei 10.639/03 est? sendo cumprida na educa??o integral

Seed germination characteristics of Phillyrea angustifolia L. and P. latifolia L. (Oleaceae), two Mediterranean shrub species having lignified endocarp

The aim of this study was to determine the germination characteristics of Phillyrea angustifolia L. and P. latifolia L. seeds in order to develop an optimized propagation protocol for Phillyrea species. Seeds of P. angustifolia and P. latifolia were collected from wild plants growing in Cáceres province (CW Spain) and Andalucía (S Spain), respectively. Percentage of water uptake for P. latifolia seeds was calculated. Seeds with and without endocarp were germinated at different constant and alternating temperatures. Seeds without endocarp were soaked in distilled water or gibberellic acid, and then set to germinate. Seeds with endocarp of both species were stratified at 5 ºC for 30 or 90 days and then the endocarp was completely removed from the seeds before they were sowed. Chemical scarification with sulfuric acid and mechanical scarification were tested on P. angustifolia seeds with endocarp. Phillyrea endocarp was permeable to water, since Phillyrea seeds with endocarp imbibed water, but water uptake was faster when the endocarp was removed. Moreover, the encodarp could interfere mechanically in the emergence of the radicle, since seed germination of Phillyrea species was promoted by the complete removal of the lignified endocarp surrounding each seed. Optimal germination temperature for both species was 15 ºC, and lower temperatures produced secondary dormancy. Soaking in distilled water or gibberellic acid did not significantly enhance seed germination. Cold stratification and chemical scarification treatments were detrimental for seed germination.

Conductivity test in seeds of different passion flower species

The objective of this work was to evaluate the use of the conductivity test as a means of predicting seed viability in seven Passiflora species: P. alata, P. cincinnata, P. edulis f. edulis, P. edulis f. flavicarpa, P. morifolia, P. mucronata, and P. nitida. Conductivity of non?desiccated (control), desiccated, and non?desiccated cryopreserved seeds was determined and related to their germination percentage. The obtained results suggest that the electrical conductivity test has potential as a germination predictor for P. edulis f. flavicarpa seed lots, but not for the other tested species. Index terms: Passiflora, seed cryopreservation, seed desiccation, seed viability

Facebook addiction and emerging adults: the influence of sociodemographic variables, family communication, and differentiation of self

The growing use of social networking sites places them among the most popular online activities. In particular, Facebook is gaining increasing numbers of users. For some individuals, such activity can develop into addictive online behaviour. The main objective of this study was to assess the influence of sociodemographic (e.g., gender, age), indi vidual (e.g., differentiation of self), and family (e.g., family communication) factors on Facebook addiction in Portu guese emerging adults aged between 18 and 30 years. The study included 403 participants, who followed a protocol in which several instruments were administered (e.g., COMPA, BSI, DSI-R, and BFAS). The results showed higher Face book use and a higher risk of addiction in individuals with the following characteristics: (1) female gender; (2) aged between 24 and 30 years; (3) lower differentiation of self; (4) physically or emotionally distanced from significant others (emotional cut-off); and (5) negative communication patterns with their parents. An association was also found between other psychopathological indicators (e.g., depression, anxiety, and interpersonal sensitivity) and Facebook use. Thus, the present study contributes to the field of research on online addictions and has implications for prevention and clinical intervention.El uso creciente de las redes sociales los ubica entre las actividades on-line más populares. Facebook, en particular, está ganando más y más usuarios y para algunas personas puede convertirse en un comportamiento adictivo on-line. El objetivo principal de este estudio fue evaluar la influen cia de factores sociodemográficos (e.g., género, edad), individuales (e.g., diferenciación del self) y familiares (e.g., comunicación familiar) en la adicción a Facebook, dentro de la población portuguesa de adultos emergentes (edad entre 18-30). Para este propósito, se recolectó una muestra de 403 participantes y se aplicó un protocolo con varios ins trumentos (por ejemplo, COMPA, BSI, DSI-R, BFAS). Los resultados mostraron que las personas: (1) mujeres, (2) con edades comprendidas entre 24 y 30 años, (3) con menor diferenciación del self, (4) que se distancian física o emocio nalmente de otras personas importantes (corte emocional) y ( 5) quienes usan un patrón negativo de comunicación con sus padres muestran un mayor uso de Facebook y un mayor riesgo de adicción. También se analizaron otros indicado res psicopatológicos (por ejemplo, depresión, ansiedad y sensibilidad interpersonal), revelando que están asociados con el adicción a Facebook. Por lo tanto, el presente estudio contribuye al campo de la investigación sobre las adicciones a internet y tiene repercusiones en la prevención y la inter vención clínica.info:eu-repo/semantics/publishedVersio

Can Conditional Cash Transfer Programs Generate Equality of Opportunity in Higlye Unequal Societies? Evidence from Brazil

This article examines whether the state, through conditional cash transfer programs (CCT), can reduce the poverty and extremely poverty in societies marred by high levels of income concentration. We focus on one of the most unequal countries in the globe, Brazil, and analyze the extent to which this country’s CCT program – Bolsa Família (BF, Family Grant) program – is able to improve the life chances of extremely poor beneficiaries, through the three major goals of PBF: First, to immediately end hunger; second, to create basic social rights related to healthcare and education; finally, considering also complementary policies, to integrate adults into the job market. The analysis relies on a quantitative survey with 4,000 beneficiaries and a qualitative survey comprised of in-depth interviews with 38 program’s participants from all the regions of the country in 2008, it means that this study is about the five first years of the PBF. In order to answer the research questions, we ran four probit analyses related: a) the determinants of the realization of prenatal care; b) the determinants of food security among BF beneficiaries, c) the determinants that adult BF recipients will return to school, d) the determinants that a BF beneficiary will obtain a job. Important results from the study are: First, those who before their participation on PBF were at the margins have now been able to access healthcare services on a more regular basis. Thus, the women at the margins who were systematically excluded – black women, poorly educated and from the North – now, after their participation in the CCT program,  have more access to prenatal care  and can now count with more availability of public healthcare network. Second, before entering the Bolsa Família program, 50.3% of the participants faced severe food insecurity. This number went down to 36.8% in very five years. Men are more likely than women; non-blacks more likely than blacks; and South and Centre-West residents more likely than Brazilians from other regions; to become food secure while participating in BF. Third, instead, that moment in 2008, a small proportion of the adult participants indeed were able to return to school and to increase their educational qualifications. The lack of technical skills and the huge predominance of informal employment are central social problems in Brazil and that the PBF has failed to address such issues. This study confirms what other previous studies have reported on: BF has had a positive impact in reducing poverty in the country. Hence the main contribution of the present study is in identifying the main determinants of unequal results among individuals participating in the BF program: why some, but not others, are more easily able to access the healthcare or to overcome food insecurity while in the program?
