description: As indicated by the observed X-ray flares, a great amount of energy could be intermediately released from the postburst central engine of gamma-ray bursts (GRBs). As a natural consequence, the GRB external shock could be energized over and over. With such a multiple energy injection model, we explore the unique X-ray afterglow light curve of GRB 050712, which exists four apparent shallow decay plateaus. Together with three early X-ray flares, the central engine of GRB 050712 is supposed to release energy at least seven times after the burst. Furthermore we find that the energy released during four plateaus are all on the same order of magnitude, but the luminosity decreases with time significantly. These results may provide some interesting implications for the GRB central engine.

description: The most famous Pre-pottery Neolithic site of Anatolia, Göbekli Tepe, since 1994 has been the subject of intensive studies due to its peculiar characteristics, linked to the presence of both circular buildings and the so-called anthropomorphic T-shaped pillars. It was supposed that its discovery would have been one of a kind, but in the next few years scholars revealed the existence of similar settlements in the area of Şanlıurfa Province. These sites, still far from being investigated, share with Göbekli Tepe the same archaeological evidences, including chronological features, size and architectural and iconographic traits. The aim of this article is to focus on the new available data, which could lead us to re-discuss the interpretive models valid up to a few years ago, as recent publications point out. New interpretive tools and excavations are required to better understand what seems to be the clue of the presence of a real cultural facies with precise connotations, amongst which an high specialized craftmanship, that was able to exploit the best limestone morphology of the territory for the construction of monumental complexes.

The IPBES Scoping document for the values assessment highlights the need to assess (1) the types of values of nature that have (or have not) been incorporated into decision-making, (2) the types of valuation approaches incorporated into decision-making, (3) the challenges that have hindered the incorporation of diverse conceptualizations of values of nature in a range of decision and policy-making contexts and (4) the implications for different stakeholders. Considering that biodiversity plays an important role in supporting agricultural systems and also that agrobiodiversity is internationally recognized as an essential element for building more sustainable, resilient and just food systems, it is common that within agrobiodiverse systems, multiple decisions are made, resulting in different outcomes for ecosystems and people. Thus, we conducted a literature review to compile and analyse information about the multiple values assigned to crops or their diversity within different agricultural contexts and social groups. We look at peer-reviewed articles where farmers’ values associated with planned agrobiodiversity are explicitly expressed. Through a collection of local cases representing a wide range of agroecosystems at the global level, we aim to gain a global vision on farmers values of agrobiodiversity.

description: The rare $K^\pm\toπ^\pmπ^0 e^+e^-$ decay, currently under analysis by the NA48/2 Collaboration, is considered. We have performed two theoretical approaches to calculate the differential decay width -- in the kaon rest frame, where we use Cabibbo-Maksimovicz variables, and in the center-of-mass system of the lepton pair. The latter essentially simplifies the computations. A comparison between the two approaches has been performed. We have also found the dependencies of the differential decay rate as a function of the virtual photon and dipion system masses

As major environmentally disruptive and irreversible projects, such as large dams and mines, pose a special challenge to decision-making, we ask whether the inclusion of marginalised values and values of marginalised people, and more inclusive approaches to incorporating knowledge in the design, appraisal and decision-making on such environmentally disruptive projects can lead to a better balance between individual and aggregate well-being, sustainability and justice, across multiple dimensions and scales. In particular, using large dams and large mines as examples, we ask, to what extent and in what manner have plural values (marginalised values for nature and society, and values of marginalised people) and knowledge been recognized and incorporated into appraisals of such “big, environmentally disruptive, irreversible” projects (recognition justice), and to what extent the affected communities themselves were heard in the appraisal and decision-making process (procedural justice), whether this led to better decisions, and translated into better long-term outcomes, and if so, what might be the factors enabling such plural appraisal and democratic decision-making about environmentally disruptive projects.

description: We present a fully self-consistent computational framework composed by Hartree-Fock plus ran- dom phase approximation where the spin-orbit and Coulomb terms of the interaction are included in both steps of the calculations. We study the effects of these terms of the interaction on the random phase approximation calculations, where they are usually neglected. We carry out our investigation of excited states in spherical nuclei of oxygen, calcium, nickel, zirconium, tin and lead isotope chains. We use finite-range effective nucleon-nucleon interactions of Gogny type. The size of the effects we find is, usually, of few hundreds of keV. There are not simple approximations which can be used to simulate these effects since they strongly depend on all the variables related to the excited states, angular momentum, parity, excitation energy, isoscalar and isovector characters. Even the Slater approximation developed to account for the Coulomb exchange terms in Hartree-Fock is not valid in random phase approximation calculations.

description: La contextualización curricular constituye un proceso a través del cual, las propuestas curriculares se ajustan a los parámetros particulares de los diversos entornos,  instituciones y colectivos donde se aplicarán. En dicho proceso, la lógica de lo general, lo estandarizado, lo prescriptivo se contrapone a la lógica de lo local, lo situacional, lo adaptativo. Se trata de una visión de la educación y de la función de las escuelas contraria a la homogeneización y respetuosa con la diversidad. Aunque el concepto de contextualización es polisémico, este artículo lo analiza desde la perspectiva de la necesaria vinculación entre las propuestas curriculares y las características del entorno físico, biológico y humano en el que se implementa. Se analiza la contextualización curricular desde 4 perspectivas: (1) el contexto como agente de construcción de la identidad de los escolares; (2) contexto e institución escolar, (3) contexto y currículo, (4) contexto y metodología didáctica. El texto concluye señalando la importancia de la contextualización curricular como mecanismo de fortalecimiento de la comunidad local y estímulo para el compromiso colectivo  en su mejora.

Discursos políticos sobre educação em Portugal: existe lugar para a contextualização curricular?

Year: 2012

description: Um dos aspetos que tem surgido de forma recorrente nos discursos políticos sobre educação diz respeito à necessidade de envolver os alunos nos processos de ensino-aprendizagem, tornando-os protagonistas na construção dos seus saberes. Esse apelo surge em resposta às críticas feitas à Escola por transmitir conhecimentos compartimentados em “pacotes disciplinares”, sem articulação entre si, dificultando uma visão global e relacional dos saberes e “fazendo dos alunos meros acumuladores das informações transmitidas, em vez de intervenientes ativos na construção desses saberes” (Cortesão, Leite & Pacheco, 2002: 34). Urge por isso que os professores trabalhem os conteúdos curriculares de modo integrado e de forma a aproximá-los das vivências dos alunos, tornando-os mais familiares e mais compreensíveis. No fundo, apela-se a que desenvolvam o currículo de uma forma mais contextualizada.

O texto que a seguir se apresenta enquadra-se num projeto de investigação sobre contextualização curricular e dá conta dos resultados obtidos na análise de diplomas e de discursos político-legais publicados no período compreendido entre 2001 e 2010.
 Em termos de resultados, a principal conclusão extraída repousa no facto de a contextualização curricular não ser taxativamente assumida nos diplomas e nos discursos políticos analisados. Existe aqui aquilo que, de forma provocatória, aqui designamos por um delito de omissão, uma vez que não deixando reconhecer a importância da contextualização curricular, os responsáveis políticos apenas a vertem nos diplomas por via indireta, através de mecanismos – flexibilização, integração, articulação e diferenciação curriculares – que, no seu conjunto, podem, eventualmente, contribuir para que o desenvolvimento do currículo se processe de forma contextualizada.

description: Weak antilocalization (WAL) and linear magnetoresistance (LMR) are two most commonly observed magnetoresistance (MR) phenomena in topological insulators (TIs) and often attributed to the Dirac topological surface states (TSS). However, ambiguities exist because these phenomena could also come from bulk states (often carrying significant conduction in many TIs) and are observable even in non-TI materials. Here, we demonstrate back-gated ambipolar TI field-effect transistors in (Bi0.04Sb0.96)2Te3 thin films grown by molecular beam epitaxy on SrTiO3(111), exhibiting a large carrier density tunability (by nearly 2 orders of magnitude) and a metal-insulator transition in the bulk (allowing effectively switching off the bulk conduction). Tuning the Fermi level from bulk band to TSS strongly enhances both the WAL (increasing the number of quantum coherent channels from one to peak around two) and LMR (increasing its slope by up to 10 times). The SS-enhanced LMR is accompanied by a strongly nonlinear Hall effect, suggesting important roles of charge inhomogeneity (and a related classical LMR), although existing models of LMR cannot capture all aspects of our data. Our systematic gate and temperature dependent magnetotransport studies provide deeper insights into the nature of both MR phenomena and reveal differences between bulk and TSS transport in TI related materials.

Its purpose was to explore whether a higher frequency of valuation studies (of ecosystem services / nature's contributions to people) in a country is associated with the likelihood of uptake of valuation by national government agencies. The analysis used two indicators to proxy the uptake of scientific valuation knowledge at national scale: (i) likelihood of ecosystem accounting implementation at national level indicated by the system of environmental economic accounting and ecosystem accounting (SEEA EA), and (ii) likelihood of reporting Aichi target 2 progress in national biodiversity strategies and action plans under the CBD (Aichi target 2 “By 2020, at the latest, biodiversity values have been integrated into national and local development and poverty reduction strategies and planning processes and are being incorporated into national accounting, as appropriate, and reporting systems”).
Actions, enrichments and universal enrichments

description: This thesis studies the relationship between actions of monoidal categories and enrichments in monoidal categories, and uses these ideas to prove the existence of universal enrichments of a category. It first details the correspondence between actions of a monoidal category 𝓥 on a category 𝓐 which are right-closed, and enrichments of 𝓐 in 𝓥 which are copowered, and explains how this restricts back to an equivalence between cocomplete enrichments of the cocomplete category 𝓐, and right-closed monoidal actions which preserve colimits in the A-variable. It then considers the locally presentable case, showing that any locally presentable category 𝓐 has an enrichment in the locally presentable monoidal category Cocts(𝓐, 𝓐) of cocontinuous endofunctors of 𝓐. It shows that this is a universal cocomplete enrichment of 𝓐, in the sense that any other cocomplete enrichment of 𝓐 is obtained from the universal one via base-change. It then considers the case of actions of braided monoidal categories 𝓥 on monoidal categories 𝓐. It shows that right-closed such actions correspond to enrichments of 𝓐 to a monoidal 𝓥-category. Again, there is a notion of universal enrichment, and the thesis concludes by sketching a proof that a locally presentable monoidal 𝓐 has a universal monoidal enrichment in its monoidal centre 𝓩(𝓐).

description: A gestão contextualizada do currículo como reivindicação pedagógica tem vindo a acentuar a importância de uma tal opção em função da necessidade de se respeitar as singularidades cognitivas e culturais dos alunos como fator fundamental da gestão do seu processo de ensino-aprendizagem. Sendo certo que este é um fator incontornável de um projeto educacional de matriz democrática, importa valorizar uma outra dimensão, a que alguns investigadores têm vindo a chamar a atenção, e que se relaciona quer com as singularidades epistemológicas dos saberes escolares quer com a historicidade dos mesmos. Trata-se de afirmar que o seu processo de construção não pode ser desprezado como um fator que obriga os docentes a refletir sobre os desafios culturais com que, a partir de tais saberes, definem os desafios curriculares que suportam a sua ação formativa nos espaços da sala de aula. É sobre uma tal problemática, e as implicações curriculares e didáticas da mesma, que este texto se debruça.

Práticas curriculares no ensino da matemática: perceções de alunos do 9.º ano de escolaridade e sua relação com a contextualização curricular

description: À disciplina de Matemática são muitas vezes associadas situações de insucesso escolar traduzidas por baixos resultados nos exames nacionais. Esta situação, que se manifesta desde o final do ensino básico (9.º ano), justifica a sua análise e o delineamento de intervenções educacionais e curriculares. Ao nível das políticas curriculares, têm sido implementadas medidas de que o Plano da Matemática (2006-2012) é um dos exemplos. Por outro lado, a bibliografia produzida no campo do currículo aponta para que práticas de contextualização curricular constituem um meio gerador de melhores aprendizagens. É no quadro destas ideias que este texto, por um lado, dá conta de uma pesquisa que recolhe opiniões de alunos sobre estratégias de ensino mais frequentemente usadas por professores de Matemática e efeitos que geram na promoção da aprendizagem e, por outro, analisa essas estratégias à luz de procedimentos de contextualização curricular. Os resultados dessa pesquisa indicam que as estratégias mais frequentes são de orientação tradicional e de aprendizagem por treino. São também, e talvez por serem aquelas com que mais convivem, aquelas que segundo os alunos constantes do estudo mais contribuem para as suas aprendizagens. Apesar disso, há o recurso a algumas estratégias de contextualização curricular por referência a conteúdos, ao sujeito/aluno e a práticas pedagógicas orientadas para a aprendizagem, mas menos as que têm por referência aspectos do contexto local.

description: As culturas epistémicas que vão sendo cada vez mais preponderantes no campo de estudos curriculares tendem a dar relevo ao trabalho essencial do currículo centrado na sua apropriação, capaz de explicitar o que devem saber e em que devem tornar-se os sujeitos para poderem cumprir a sua cidadania. O conceito de contextualização curricular operacionaliza a finalidade referida. O presente texto pretende saber se nas escolas o esforço de contextualização curricular está presente nas práticas pedagógicas dos professores e se tal esforço é entendido pelos estudantes como modos de contribuir para aprendizagens mais significativas e bem sucedidas.
 O trabalho empírico realizado usou uma amostra ocasional constituída por 12 professores e alunos de 12 turmas de disciplinas das áreas das Expressões (Educação Visual e Educação Musical) do 3.º ciclo do Ensino Básico. Os professores entendem e praticam a contextualização curricular sobretudo de acordo com os referenciais do aluno, dos seus interesses e do local, pese embora os resultados ficarem sempre aquém do planeado. Já os alunos valorizam as aprendizagens realizadas em relação ao seu futuro, e tendem a privilegiar a dimensão vocacional e utilitária em detrimento de uma formação mais geral.

description: By using standard broad-band VRI photometry we were able to discriminate the variations of the broad hydrogen alpha line from the continuum variations for the active galaxy Mkn 279. Cross-correlating both light curves enabled us to determine the time lag of the broad line variations behind the continuum and thus to determine the BLR size (about 8 light days). Our preliminary results are rather consistent with the spectroscopic reverberation mapping results (about 12/17 days). This study is a part of an ambitious program to perform photometric reverberation mapping and determine BLR sizes (respectively - the central black hole masses) for more that 100 nearby AGN.

description: We show that the Nakayama automorphism of a Frobenius algebra $R$ over a field $k$ is independent of the field (Theorem 4). Consequently, the $k$-dual functor on left $R$-modules and the bimodule isomorphism type of the $k$-dual of $R$, and hence the question of whether $R$ is a symmetric $k$-algebra, are independent of $k$. We give a purely ring-theoretic condition that is necessary and sufficient for a finite-dimensional algebra over an infinite field to be a symmetric algebra (Theorem 7).

description: A contextualização curricular é um conceito relativamente recente nos discursos educacionais e a que têm sido associados vários sentidos (Fernandes, Leite, Mouraz e Figueiredo, 2012). De entre esses sentidos sobressai o de que a contextualização curricular representa uma possibilidade pedagógica para promover a melhoria das aprendizagens dos alunos e, consequentemente, o seu sucesso escolar. Nesse sentido, as práticas pedagógicas desenvolvidas pelos professores afiguram-se como podendo, ou não, contribuir para o alcance daquele objetivo. Neste artigo, a partir do ponto de vista de um conjunto de professores, clarificam-se vantagens e constrangimentos do recurso a práticas de contextualização curricular. Globalmente, os resultados apontam para uma valorização do recurso a essas práticas reconhecendo-se serem uma via configuradora de processos de ensino-aprendizagem mais significativos para os alunos.

description: Herein, three multifunctional 3',4'-bis(alkyloxy)-2,2':5',2"-terthiophene comprising monomers with different alkyl chains were electrochemically polymerized on an ITO electrode to obtain the polymers; poly(3',4'-dibutoxy-2,2':5',2"-terthiophene) (P1), poly(3',4'-bis(hexyloxy)-2,2':5',2"-terthiophene) (P2), and poly(3',4'-bis(octyloxy)-2,2':5',2"-terthiophene) (P3). Cyclic voltammetry and in situ spectroelectrochemical studies were performed for the polymers to investigate their oxidation potentials, HOMO/LUMO energy levels, band gaps (Egop), optical contrasts (T%), and switching times. All polymers had an optical band gap at around 1.8 and 1.9 eV and revealed different tones of red color in their neutral states and different tones of blue color in their oxidized states with similar electrochromic features. This means that the alteration of the alkyl chain lengths did not affect the band gap and the colors of the resulting polymers significantly. When P1, P2, and P3 were compared in terms of electrochromic contrast and switching studies, P1 had superior optical contrast and switching time values. P1 exhibited 51% optical contrast at 520 nm which is a rare and desired property for π-conjugated conducting polymers in the visible region. P1, P2 and P3 conducting polymer films, which were also used for energy storage applications before, revealed promising electrochromic characters in this study, so these poly(3',4'-bis(alkyloxy)-2,2':5',2"-terthiophene) derivatives can be called as multifunctional next-generation materials.
Curriculum for excellence: transformational change or business as usual?

description: Scotland’s Curriculum for Excellence (CfE) is a good example of a new breed of national curriculum; a curricular model that seeks to combine top-down government prescription with bottom-up school-based curriculum development by teaching professionals. However, in developing a renewed view of teachers as agents of change and relaxing curriculum prescription, CfE has attracted criticism for its vagueness in terms of content and for a mix-and-match approach and seemingly atheoretical design. This paper engages in a critique of CfE, and proposes a process by which practitioners may make sense of and enact the new curriculum.

O papel do contexto nas tarefas matemáticas

Publisher: name: Interacções
Year: 2012

description: Neste artigo, tendo por base a noção de modelo matemático, analisamos o papel do contexto nas tarefas matemáticas. Entendemos como contexto o universo experiencial associado a cada tarefa, que pode remeter para um campo da vida quotidiana em que o aluno tem maior ou menor experiência pessoal, ou remeter para o universo matemático. Começamos por apresentar diferentes abordagens sobre o papel do contexto nas tarefas matemáticas para, numa segunda parte, analisarmos exemplos de resolução por alunos de tarefas com vários contextos, procurando identificar as suas implicações no processo de aprendizagem. Argumentamos que na aprendizagem da Matemática os alunos precisam de trabalhar em diversos contextos – realísticos, de semi-realidade e matemáticos. Em cada tarefa, a atividade do aluno terá por base não só as suas experiências em contextos da realidade como as suas experiências matemáticas anteriores. Progressivamente ir-se-á libertando da necessidade de contextos da realidade, trabalhando num nível cada vez mais formal, sendo capaz de recorrer a contextos informais sempre que necessário. Deste modo, a própria Matemática constitui um contexto onde os alunos devem saber trabalhar. Além disso, o contexto de trabalho na sala de aula desempenha também um papel fundamental, devendo ser marcado por circunstâncias favoráveis à aprendizagem, de modo a estimular a interação construtiva entre os alunos, decorrente do trabalho do professor mais como orientador das aprendizagens do que como fonte exclusiva do saber e ser rico em materiais e tecnologias, onde os alunos se possam sentir confortáveis em apresentar o seu pensamento e argumentar as suas opiniões.

description: The NEANIAS EU project develops thematic services for EOSC communities in the field of Underwater, Atmospheric and Space research. The integration of the thematic services into the EOSC ecosystem together with the investigation of the possibility of onboarding a number of core services to EOSC as well are among the main project targets to pursue. Furthermore, the reuse of EOSC services for the purposes of NEANIAS services is another key challenge of the project towards EOSC integration.
 This white paper presents an overview of the NEANIAS journey towards EOSC integration; from the preparation of an initial integration plan to its realisation through the onboarding of NEANIAS services on EOSC marketplace. The white paper emphasises on experiences gathered, issues encountered and lessons learnt throughout this journey, which may prove helpful to other service providers planning for EOSC onboarding.

title: Propagation in the Galactic magnetic field - Effects on the spectrum, composition and anisotropy of Galactic and extragalactic cosmic rays
Creators: name: Kääpä, Alex
Publisher: name: Bergische Universität Wuppertal
Year: 2022

description: This dissertation treats the propagation effects that the Galactic magnetic field imposes on cosmic rays in the rigidity range matching the transition region from Galactic to extragalactic cosmic rays. Two main topics are covered. The first topic deals with the relation of these propagation effects with the structure of the Galactic magnetic field. The rigidity range matching the transition region also signifies a change in propagation regimes from diffusive to ballistic. We show that changes in the rigidity dependence of key parameters occur at rigidities, where the corresponding gyro radius matches typical length scales of the Galaxy for typical magnetic field strengths. We further lay out how the changes in propagation regimes lead to important rigidity-dependent effects in the trajectories of both Galactic and extragalactic cosmic rays. At the lowest rigidities, Galactic cosmic rays propagate diffusively in the Galactic plane leading to a confinement therein. As rigidity increases, confinement decreases and particles more readily leak out of the Galaxy. Extragalactic cosmic rays at the lowest rigidities are partly shielded by the strong magnetic fields in the Galactic plane region, while those that manage to penetrate into the Galactic plane are confined therein. Both of these effects weaken as rigidity increases. In the second topic, the modifications that these propagation effects impose on cosmic ray observables are explored. Galactic cosmic rays experience a flux suppression towards higher rigidities due to their decreased confinement (or increased leakage), which naturally also leads to a modification of the composition towards a heavier mean mass. The shielding and confinement of extragalactic cosmic rays counteract exactly, such that the Galactic magnetic field does not create any flux modifications or anisotropies if they are injected isotropically into the Galaxy. In the case of anisotropic injection, extragalactic cosmic rays are strongly isotropised when propagating through the Galactic magnetic field. Anisotropies above the %-level only survive above ~ 1 EV in the form of a dipole. However, due to the shift in rigidity of the regions in the sky of highest magnetic transparency, flux modifications can arise, the nature of which depends on the nature of the anisotropy. Injected dipoles lead to more subtle changes in the spectrum in the form of a change in slope, whereas injected point sources can give rise to spectral breaks. These results are finally contextualised in form of their implications on the transition region.

description: Los conceptos de ciudadanía e interculturalidad en la educación cada vez se encuentran más interrelacionados, ya que se trata de formar ciudadanos activos que se relacionan con personas de distintas culturas que aportan el enriquecimiento intercultural para vivir en sociedades multiculturales.

Ciudadanía e Interculturalidad son base de todo proyecto y sistema educativo. Desde Europa se ha tratado estos conceptos desde hace varios años y en distintos informes, proyectos, tratados, recomendaciones, etc., realizados principalmente desde el Consejo de Europa.

A lo largo de este documento expondremos qué entendemos de los conceptos de ciudadanía, interculturalidad e identidad y su sentido dentro de la dimensión europea de la educación, la cual persigue la construcción de una identidad intercultural en todos los ciudadanos europeos.

Ahora bien, ¿cómo se construye la identidad europea? ¿en qué consiste? ¿cómo se logra formar ciudadanos europeos en estos aspectos? Desde la escuela, como lugar de aprendizaje y encuentro entre personas y donde se adquieren las competencias necesarias para lograr el pleno desarrollo del individuo y la construcción de una identidad propia, basada en la interculturalidad y la ciudadanía activa y enmarcada en la sociedad multicultural en la que nos encontramos. En definitiva, a través de la Educación para la Ciudadanía Democrática e Intercultural como modelo inclusivo de construcción de la identidad europea.

description: Dress, clothing and sartorial practices are important forms of self-expression and communication with the social body. However, some forms of dress and their meanings have been politicized: Muslim sartorial practices, seen as a homogenous embodiments of tradition, have been highly criticized in western European countries. This article looks at the sartorial practices of young Pakistani women in the Netherlands, arguing that heterogeneity is the main characteristic of Muslim minorities while dressing practices are as much the product of tradition as a continuous innovation and engagement with fashion.

description: A fim de analisarmos as representações sociais da prostituição e a percepção de preconceito e estigmatização por parte das prostitutas, realizamos dois estudos em Aracaju no nordeste do Brasil. A pesquisa foi realizada em Janeiro de 2008, os dois estudos utilizaram entrevistas estruturadas. O primeiro deles foi realizado com 66 moradores de diversos bairros desta cidade o segundo estudo envolveu nove prostitutas concentradas na Orla de Aracaju. Análises de conteúdos das respostas do primeiro estudo indicaram que a prostituição é representada pelos entrevistados como exclusão social, imoral, aversiva ou estranha e as prostitutas são demonizadas. No segundo estudo verificamos que as prostitutas se sentem vítimas de preconceito e consideram estar numa situação de exclusão e estigmatização. Esses resultados são discutidos à luz das teorias sobre estigmatização e exclusão social.
