Analysis about the society of 'Pa Negre' (Agustí Villaronga, 2010)

This article has developed with the intention of analyzing how the stereotypes, prejudices and lies can influence the education of the children. Formation, that usually comes from family and teachers, who sometimes move for extremist ideologies. There exist multiple fictions in which we observe these social archetypes, but it is the case of the movie Pa negre (Agustí Villaronga, 2010), where the principal personage evolves psychologically, because of that its eyes observe and the ideas that the people transmit him on its family, in the rural environments, where the tradition of the rumors coexists.

The anomaly in the candidate microlensing event PA-99-N2

The light curve of PA-99-N2, one of the recently announced microlensing candidates toward M31, shows small deviations from the standard Paczynski form. We explore a number of possible explanations, including correlations with the seeing, the parallax effect, and a binary lens. We find that the observations are consistent with an unresolved red giant branch or asymptotic giant branch star in M31 being microlensed by a binary lens. We find that the best-fit binary lens mass ratio is similar to1.2x10(-2), which is one of the most extreme values found for a binary lens so far. If both the source and lens lie in the M31 disk, then the standard M31 model predicts the probable mass range of the system to be 0.02-3.6 M-circle dot (95% confidence limit). In this scenario, the mass of the secondary component is therefore likely to be below the hydrogen-burning limit. On the other hand, if a compact halo object in M31 is lensing a disk or spheroid source, then the total lens mass is likely to lie between 0.09 and 32 M-circle dot, which is consistent with the primary being a stellar remnant and the secondary being a low-mass star or brown dwarf. The optical depth (or, alternatively, the differential rate) along the line of sight toward the event indicates that a halo lens is more likely than a stellar lens, provided that dark compact objects comprise no less than 15% (or 5%) of halos.

High-efficiency low-voltage-stress Class-EF PA with extended maximum operating frequency

The Class-EF power amplifier (PA) introduced recently has a peak switch voltage much lower than the well-known Class-E PA. However, the value of the transistor output capacitance at high frequencies is typically larger than the required Class-EF optimum shunt capacitance. As a result, softswitching operation that minimizes power dissipation during OFF-to-ON transient cannot be achieved at high frequencies. A novel Class-EF topology with transmission-line load network proposed in this paper allows the PA to operate at much higher frequencies without trading the other figures of merit. Closed-form formulations are derived to simultaneously satisfy the Class-EF impedances requirement at fundamental frequency, all even harmonics, and the first two odd harmonics as well as to provide matching to 50O load. © 2011 Institut fur Mikrowellen.

Hydroclimatic shifts in northeast Thailand during the last two millennia - the record of Lake Pa Kho

The Southeast Asian mainland is located in the central path of the Asian summer monsoon, a region where paleoclimatic data are still sparse. Here we present a multi-proxy (TOC, C/N, δ¹³C, biogenic silica, and XRF elemental data) study of a 1.5m sediment/peat sequence from Lake Pa Kho, northeast Thailand, which is supported by 20 AMS ¹⁴C ages. Hydroclimatic reconstructions for Pa Kho suggest a strengthened summer monsoon between BC 170-AD 370, AD 800-960, and after AD 1450; and a weakening of the summer monsoon between AD 370-800, and AD 1300-1450. Increased run-off and a higher nutrient supply after AD 1700 can be linked to agricultural intensification and land-use changes in the region. This study fills an important gap in data coverage with respect to summer monsoon variability over Southeast Asia during the past 2000 years and enables the mean position of the Intertropical Convergence Zone (ITCZ) to be inferred based on comparisons with other regional studies. Intervals of strengthened/weaker summer monsoon rainfall suggest that the mean position of the ITCZ was located as far north as 35°N between BC 170-AD 370 and AD 800-960, whereas it likely did not reach above 17°N during the drought intervals of AD 370-800 and AD 1300-1450. The spatial pattern of rainfall variation seems to have changed after AD 1450, when the inferred moisture history for Pa Kho indicates a more southerly location of the mean position of the summer ITCZ.

Cartografia educacional da Freguesia de Vila Nova de São Bento

O presente trabalho visa conhecer e caracterizar as aprendizagens promovidas pelas principais instituições da freguesia de Vila Nova de S. Bento (concelho de Serpa), avaliando a presença relativa dos contextos formais, não – formais e informais. Realizámos uma abordagem teórica, com o intuito de precisar alguns conceitos chave como aprendizagem, ambientes de aprendizagem e território. Para concretizar o trabalho empírico, e tendo como base as questões subjacentes à investigação, utilizámos uma metodologia mista (quantitativa/qualitativa) com uma aproximação conceptual ao estudo de caso. O instrumento utilizado na recolha de dados foi o inquérito por questionário aplicado. Fizemos uma recolha, análise e interpretação de dados que nos permitiram inferir:  As instituições objecto do nosso estudo constituem um potencial educativo no território analisado;  Estas instituições desenvolvem um conjunto de actividades de aprendizagem que poderão ser um recurso para o território;  Estabelecida uma relação de diálogo com a escola e outros parceiros locais, será possível potenciar novas ofertas educativas neste território. Terminámos este trabalho, com a apresentação de algumas recomendações e sugestões, que poderão vir a integrar novas investigações; ### Abstract: The present study aims to now and characterizes the learning’s promoted by the main institutions in the town of Vila Nova de S. Bento (Serpa), evaluating the relative presence of formal, non-formal and informal contexts. We made a theoretical approach, aiming to precise some key concepts, like learning ambient and territories. To realise the empiric work, and having as base subjacent questions to the investigation, we used a mixed methodology (quantitative/qualitative) as a conceptual approach to the case study. The instrument used in the recollection of data was an inquiry by applied questioner. We made a recollection, analysis and interpretation of data witch permitted as to infer:  The institutions which we observed in our study have an educative potential,  These institutions developed a series of learning activities that might be a good source for the territory,  Establishing a relationship between the school and the other local partners, it will be possible to potentiate the learning offers. We end this study by presetting some recommendations and suggestions that might be integrated in new investigations.

As aprendizagens não formais e informais no ingresso à Escola Secundária Padre António Macedo: possíveis parcerias com outras instituições de Vila Nova de Santo André

Esta investigação teve como principal objectivo avaliar da presença dos contextos institucionais não formais e informais no conjunto das aprendizagens reveladas pelos estudantes que ingressaram, na Escola Secundária Padre António Macedo, no ano lectivo 2009-2010, e averiguar qual o contributo das instituições locais no seu percurso de aprendizagem. A abordagem metodológica assentou num dispositivo de matriz quantitativa, com o recurso ao inquérito por questionário a uma amostra de alunos. Observámos um potencial educativo na cidade proporcionado por instituições, onde se destacaram amigos, familiares e clubes desportivos, procurados pelos jovens para satisfazer a sua necessidade de conhecimento e ocupar tempos livres. Sendo as áreas com mais episódios de aprendizagens, extra escolares: saúde, cidadania, desporto e artes, os jovens reconheceramse detentores de conhecimentos propiciados pela comunidade e instituições locais; ABSTRACT: This research had, as main aim, to assess the presence of formal and informal institutional contexts in all the learnings revealed by the students who enrolled Escola Secundária Padre António Macedo in the year 2009-2010, and also to determine what contribution local institutions had in their learning. The methodological approach was based on a quantitative matrix device, by applying a questionnaire survey to a sample of students. We saw an educational potential offered by institutions in the city, where the highlights were friends, family and sports clubs, popular among young people to satisfy their need for knowledge and to occupy their free time. The areas with more episodes of extra school learning were: health, citizenship, sport and arts. Young people recognized themselves in possession of knowledge provided by the community and local institutions.
