Nem justa, nem injusta: Discriminadora. As Mulheres e a guerra.
Creators: name: Henriques, Fernanda
Publisher: name: Medi@ções
Year: 2017

description: Que pode uma reflexão filosófica fazer ao tema as Mulheres e a guerra? A que meandros discursivos obriga uma tal reflexão? Que horizontes devem ser convocados? Os gerais, sobre as guerras? Os particulares e empíricos sobre esta ou aquela guerra? Os temporais? E a ser assim, dentro de que quadro? Por exemplo, se se tomar em linha de conta as guerras a partir do século XX, poderá haver a mesma abordagem reflexiva à guerra de 14/18 e às guerras da década de 1990, como é o caso da ex-Jugoslávia, ou às novíssimas guerras, do século XXI? Por outro lado, que quadro epistemológico pode ser convocado dentro dos campos, já muito latos, que hoje abordam a questão das Mulheres e da guerra? Estas e outras interrogações levaram-me a considerar importante definir alguns pontos que esclarecessem quer o lugar de análise do presente texto, quer o consequente nó problemático que ele engendra

description: We present and analyze the positions, distances, and radial velocities for over 4000 blue horizontal-branch (BHB) stars in the Milky Way's halo, drawn from SDSS DR8. We search for position-velocity substructure in these data, a signature of the hierarchical assembly of the stellar halo. Using a cumulative "close pair distribution" (CPD) as a statistic in the 4-dimensional space of sky position, distance, and velocity, we quantify the presence of position-velocity substructure at high statistical significance among the BHB stars: pairs of BHB stars that are close in position on the sky tend to have more similar distances and radial velocities compared to a random sampling of these overall distributions. We make analogous mock-observations of 11 numerical halo formation simulations, in which the stellar halo is entirely composed of disrupted satellite debris, and find a level of substructure comparable to that seen in the actually observed BHB star sample. This result quantitatively confirms the hierarchical build-up of the stellar halo through a signature in phase (position-velocity) space. In detail, the structure present in the BHB stars is somewhat less prominent than that seen in most simulated halos, quite possibly because BHB stars represent an older sub-population. BHB stars located beyond 20 kpc from the Galactic center exhibit stronger substructure than at $\rm r_{gc} < 20$ kpc.

Year: 2017

description: O ensaio discute o pepel da arte nas suas diversas formas como recurso relevante de educação intercultural, sobretudo atendendo às características do mundo atual (sociedade da informação, multiculturais e global) e às características dos estudantes nativos digitais. A comparação entre os conceitos de arte e de diálogo intercultural permite argumentar que a arte e u recursos ideal para a com-preensão do mundo, para a expressão de ideias e para estabelecer pontes com pessoas de outras culturas porque, sendo uma linguagem cognitiva e emocional, consegue simbolizar mensagens que atravessam as fronteiras culturais e permitem sintonizar culturas e identidades. Finalmente, é feita a apologia de práticas de ensino que integram a estética artística e conclui-se que os professores devem desenvolver, no paradigma de ensino que se está a formar, um novo repertório de competências, fortalecendo a capacidade intercultural, a sensibilidade artística, a aptidão para manusear as ferramentas informáticas e sobretudo, uma nova mentalidade sobre o que significa ser professor hoje.

description: Introduzione: Al giorno d’oggi la parola emozione è sovente nominata nell’ambito educativo. Docenti ed educatori sono sempre più interessati nel capire come le sensazioni emotive dello studente possono avere un ruolo nella sua crescita caratteriale e formativa. A seguito di questo interesse, diverse ricerche scientifiche sono state svolte su questo tema. Sulla base dei risultati di questi studi, con il mio lavoro ho voluto scoprire il mondo delle emozioni a Educazione fisica. Obiettivo: Lo scopo di questa ricerca è di comprendere come un alunno percepisce le proprie emozioni, quali sono quelle più vissute e come riesce a distinguerle in Educazione fisica. Inoltre, questo studio vuole approfondire in modo specifico l’intelligenza emotiva e provare a capire come essa si sviluppa nel tempo. Metodo: Questa ricerca segue una metodologia qualitativa. Il lavoro si basa su delle interviste. Sono stati intervistati nove alunni di cui tre studenti di terza elementare, tre di quinta elementare e tre di terza media. L’analisi è stata eseguita seguendo il principio dell’analisi di testo (Smith, 1995). Risultati: Le emozioni più presenti durante le ore di educazione fisica sono la felicità, la tristezza e la rabbia. Inoltre, lo studio mostra come la descrizione delle proprie emozioni e quelle degli altri diventi maggiormente precisa più l’età del soggetto interpellato aumenta. Relatore: Francesco Canuti.

Construindo pontes e travessias: das mediações sociais à mediação intercultural

description: Neste texto clarificam-se alguns conceitos e pilares habitualmente afetos à mediação. Particularmente, distingue-se a mediação intercultural que dentro de todas as mediações sociais é a que mais investe na prevenção, transformação, educação e reabilitação. Discute-se a neutralidade e a imparcialidade e sugere-se a opção pelo conceito de multiparcialidade que permite conciliar a empatia com as partes, no sentido da compreensão émica, e, simultaneamente, com a busca da equidade. Critica-se o uso abusivo do conceito de tolerância e propõe-se o de respeito como pilar da convivência entre diferentes. Assume-se a mediação intercultural como tendo potencialidade para atravessar todas as mediações socioculturais (familiar, comunitária, pessoal, laboral, escolar...) se se assumir o intercultural como paradigma que rompe com o culturalismo. Desta forma, a mediação intercultural não está presente apenas em contextos de forte multiculturalidade como é o exemplo da coexistência de pessoas migrantes.

description: This article traces the way in which immigration in Britain and Portugal has changed over the past thirty years or so. It notes the way in which immigration in each country has followed a similar path, with Portugal following the patterns established earlier in Britain. It points out how immigration from the former colonies has been eclipsed by immigration from Europe since joining the European Union and describes some of the effects on schools of the resulting linguistic diversity. It concludes by describing some of ways in which education professionals can respond to such diversity for the good of all.

Educação e Diversidade Linguística em Portugal
Creators: name: Pinto, Paulo Feytor
Publisher: name: Medi@ções
Year: 2017

description: Desde os últimos anos do século XX, a diversidade de línguas vivas disponíveis no currículo dos ensinos básico e secundário tem vindo paulatinamente a aumentar. Nas décadas anteriores, além do português, as outras línguas aprendidas antes do ensino superior eram o inglês, o francês e o alemão, todas disponíveis como primeira língua estrangeira, a partir do 5º ano. O processo de abertura à diversidade linguística encetou-se com a introdução do espanhol, como segunda língua estrangeira, no 3º ciclo do ensino básico, em 1997. Nos anos seguintes, as novas línguas introduzidas no currículo foram duas línguas originárias de Portugal, a língua gestual portuguesa (LGP) e o mirandês. Já na segunda década do século XXI, o mandarim está a ser aprendido por centenas de alunos do 1º ciclo do ensino básico e do ensino secundário. A introdução no currículo de duas línguas estrangeiras, espanhol e mandarim, e de duas línguas autóctones, LGP e mirandês, parece ser um caso paradigmático da influência que fatores externos podem ter sobre o funcionamento de um sistema ecolinguístico. Parece ainda evidente que a oferta destas línguas não se insere numa política de educação linguística consistente, mas é antes um conjunto de respostas a problemas linguísticos independentes.

Teachers’ perceptions and concerns while implementing student-centred teaching strategies in the classroom in Saudi Arabia
Creators: name: Aladawi, Wojdan
Publisher: name: University of British Columbia
Year: 2020

description: Abstract In Saudi education, the teacher-centred approach has been the norm for many decades. Recently, public-school teachers were asked to implement student-centred strategies in their classrooms. This study was conducted to examine the perceptions and concerns of seven public-school teachers about the implementation of student-centred strategies and whether school level or subject affects the use of this approach. Data was collected through semi-structured individual interviews, background questionnaires, and the open-ended statement of concerns. Teachers were asked about the beliefs, understandings, concerns and challenges they face when implementing SC strategies and about current Saudi curricular design in relation to these strategies. The Stages of Concern Model was used to assess teachers’ concerns regarding a student-centred approach (Hall & Hord, 1987; George, Hall, & Stiegelbauer, 2006). A content analysis and an inductive analysis approach were used to analyze the study data. Findings from the Statement of Concern data indicated that participants showed the most concerns in the Management Stage (task concerns), while the Unconcerned and Refocusing stages were absent among all participants. Findings from the interview data revealed two main themes: (1) modifications to textbooks, curriculum design, evaluation method, and preparation; and (2) opportunities that the student-centred approach provides within Saudi education. The school level and subject being taught also affected the teacher’s capacity to utilize student-centred strategies in Saudi schools.

description: Lately, many phenomena in both applied and abstract mathematics and related disciplines have been expressed in terms of high order and fractional PDEs. Recently, Allouba introduced the Brownian-time Brownian sheet (BTBS) and connected it to a new system of fourth order interacting PDEs. The interaction in this multiparameter BTBS-PDEs connection is novel, leads to an intimately-connected linear system variant of the celebrated Kuramoto-Sivashinsky PDE, and is not shared with its one-time-parameter counterpart. It also means that these PDEs systems are to be solved for a family of functions, a feature exhibited in well known fluids dynamics models. On the other hand, the memory-preserving interaction between the PDE solution and the initial data is common to both the single and the multi parameter Brownian-time PDEs. Here, we introduce a new---even in the one parameter case---proof that judiciously combines stochastic analysis with analysis and fractional calculus to simultaneously link BTBS to a new system of temporally half-derivative interacting PDEs as well as to the fourth order system proved earlier and differently by Allouba. We then introduce a general class of random fields we call inverse-stable-Lévy-time Brownian sheets (ISLTBSs), and we link them to $β$-fractional-time-derivative systems of interacting PDEs for $0

description: Sickle cell disease (SCD) and apolipoprotein L1 (APOL1) G1/G2 variants increase chronic kidney disease (CKD) risk in African Americans by poorly understood mechanisms. We applied bioinformatics to identify new candidate genes associated with SCD-related CKD. An interaction network demonstrated APOA1 connecting haemoglobin subunit β (HBB) and APOL1 with 36 other candidate genes. Gene expression revealed upregulation of engulfment and cell motility 1 (ELMO1) and downregulation of APOA1 in the kidney cortex of SCD versus non-SCD mice. Analysis of candidate genes identified ELMO1 rs10951509 to be associated with albuminuria and APOA1 rs11216132 with haemoglobinuria in patients with SCD. A bioinformatic approach highlights ELMO1 and APOA1 as potentially associated with SCD nephropathy.

Revisitamos alguns conceitos na formação de professores no séc. XX, citando autores de relevância, para, depois, nos centrarmos na formação para a multi-interculturalidade e, concretamente, nos desafios para uma formação de professores que responda à diversidade cultural das sociedades atuais. Privilegiamos James Banks nesta abordagem, procurando demonstrar como as cinco dimensões da educação multicultural, por si defendidas em 1985, se mantêm atuais e pertinentes no trabalho do professor/formador/educador.

description: Rich recirculation patterns have been recently discovered in the electrically conducting flow subject to a local external magnetic termed "the magnetic obstacle" [Phys. Rev. Lett. 98 (2007), 144504]. This paper continues the study of magnetic obstacles and sheds new light on the core of the magnetic obstacle that develops between magnetic poles when the intensity of the external field is very large. A series of both 3D and 2D numerical simulations have been carried out, through which it is shown that the core of the magnetic obstacle is streamlined both by the upstream flow and by the induced cross stream electric currents, like a foreign insulated insertion placed inside the ordinary hydrodynamic flow. The closed streamlines of the mass flow resemble contour lines of electric potential, while closed streamlines of the electric current resemble contour lines of pressure. New recirculation patterns not reported before are found in the series of 2D simulations. These are composed of many (even number) vortices aligned along the spanwise line crossing the magnetic gap. The intensities of these vortices are shown to vanish toward to the center of the magnetic gap, confirming the general conclusion of 3D simulations that the core of the magnetic obstacle is frozen. The implications of these findings for the case of turbulent flow are discussed briefly.

description: Questa ricerca nasce dal mio interesse verso il mondo ludico e verte sull’analisi dell’incisività del gioco sull’apprendimento in una classe di quarta elementare del Locarnese. Con questa ricerca si va ad analizzare l’impatto che hanno i giochi concernenti le misure di massa sull’apprendimento. Per verificare ciò sono stati creati appositi giochi, partendo dagli interessi dei bambini ed in seguito svolti per cinque lezioni a cadenza settimanale. L’ambito di ricerca, i traguardi di competenza e specifici sono rintracciabili all’interno del Piano di studio della scuola dell’obbligo ticinese (Divisione della scuola, 2022). I dati sono stati ricavati tramite una raccolta concezioni iniziale e finale, delle griglie osservative e dei protocolli legati ai momenti di metariflessione. Ulteriori informazioni sono state annotate in un diario di lavoro. Gli interventi svolti in classe hanno confermato le mie ipotesi di partenza e dimostrato che i giochi didattici possono avere un’influenza sull’apprendimento della matematica, più o meno significativa. Negli allegati si possono trovare tutte le carte e i tabelloni realizzati per questo percorso. Relatore: Ramon Sommerhalder.

description: Superconductor-insulator-superconductor (SIS) mixers are used in the most sensitive heterodyne receivers for sub-mm and mm waves. SIS mixers are installed on all state of the art sub-mm observatories such as the Atacama Pathfinder Experiment (APEX) and the Atacama Large Millimeter Array (ALMA). While sensitivity of an SIS mixer is quantum limited a current state of the art performance of receiver systems can still be improved. In this report we summarize our development effort to improve SIS mixer performance in several frequency bands that are relevant for the ground based astronomy. We have calculated, fabricated and measured a optimized mixer design for the 211-275 GHz frequency range, which could be used for LLAMA observatory in Argentina, for the Millimetron space mission and additional stations in the VLBI network of the Event Horizon Telescope. For the near future development we consider a 2SB mixer design for the 211-275 GHz which is conceptually close to the successful ALMA Band 9 2SB mixer. A receiver is based on single SIS mixer connected to RF hybrid block. The mixer design was developed using 3D electromagnetic modeling in CST microwave studio. The mixer is based on Nb/AlOx/Nb SIS junction embedded in a Nb/SiO2/Nb microstrip line. A good matching between a 500x1000 µm waveguide and the SIS junction was achieved by using quasi-triangle orthogonal waveguide single-sided or double-sided probes. We improved further our modeling approach for the Band 9 mixers which demonstrated an IF bandwidth of up to 20 GHz. We also optimized a mixer design for 790-950 GHz band. The mixer description and achieved performances will be presented at the conference.

description: O património como conceito operativo para a construção identitária e a Cidade como construção multidimensional e contexto interativo de aprendizagem, desafiam as políticas culturais, de desenho e regeneração urbana a desenvolverem processos inclusivos de mediação cultural, que propiciem a transformação e inovação, promovendo chaves de leitura do território e espaço público. A relação da memória com práticas artísticas tem vindo a afirmar-se em experiências de educação patrimonial, resgate de memórias e políticas de arte-pública, como meios e processos possibilitadores de cidadania, na construção de uma cartografia feita das experiências pessoais e coletivas, de consciência dos lugares que se habitam, de saberes e de códigos partilhados.

description: Cryptocurrencies return cross-predictability and technological similarity yield information on risk propagation and market segmentation. To investigate these effects, we build a time-varying network for cryptocurrencies, based on the evolution of return cross-predictability and technological similarities. We develop a dynamic covariate-assisted spectral clustering method to consistently estimate the latent community structure of cryptocurrencies network that accounts for both sets of information. We demonstrate that investors can achieve better risk diversification by investing in cryptocurrencies from different communities. A cross-sectional portfolio that implements an inter-crypto momentum trading strategy earns a 1.08% daily return. By dissecting the portfolio returns on behavioral factors, we confirm that our results are not driven by behavioral mechanisms.

description: We use Lorentzian signature AdS/CFT duality to study a first order phase transition in strongly coupled gauge theories which is akin to the chiral phase transition in QCD. We discuss the relation between the latent heat and the energy (suitably defined) of the component of a D-brane which lies behind the horizon at the critical temperature. A numerical simulation of a dynamical phase transition in an expanding, cooling Quark-Gluon plasma produced in a relativistic collision is carried out.

From Surface Operators to Non-Abelian Volume Operators in Puff Field Theory
Creators: name: Sahakian, Vatche
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Puff Field Theory is a low energy decoupling regime of string theory that still retains the non-local attributes of the parent theory - while preserving isotropy for its non-local degrees of freedom. It realizes an extended holographic dictionary at strong coupling and dynamical non-local states akin to defects or the surface operators of local gauge theories. In this work, we probe the non-local features of PFT using D3 branes. We find supersymmetric configurations that end on defects endowed with non-Abelian degrees of freedom. These are 2+1 dimensional defects in the 3+1 dimensional PFT that may be viewed as volume operators. We determine their R-charge, vacuum expectation value, energy, and gauge group structure.

description: Four previously undescribed isochromanes were isolated from the fermentation broth of an endophytic fungus Aspergillus fumigatus, which was obtained from the fruiting body of Cordyceps sinensis. Their structures were elucidated through extensive spectroscopic analyses. One racemic isochromane was further purified by chiral HPLC to yield a pair of enantiomers and their absolute configurations were determined by quantum chemical ECD calculations. These isolated compounds were evaluated for cytotoxicity against two cell lines (MV4-11 and MDA-ME-231) and the result showed that compounds 1a and 2 exhibited moderate growth inhibition against MV4-11 cell line.

description: Single quantum emitters like atoms are well-known as non-classical light sources which can produce photons one by one at given times, with reduced intensity noise. However, the light field emitted by a single atom can exhibit much richer dynamics. A prominent example is the predicted ability for a single atom to produce quadrature-squeezed light, with sub-shot-noise amplitude or phase fluctuations. It has long been foreseen, though, that such squeezing would be "at least an order of magnitude more difficult" to observe than the emission of single photons. Squeezed beams have been generated using macroscopic and mesoscopic media down to a few tens of atoms, but despite experimental efforts, single-atom squeezing has so far escaped observation. Here we generate squeezed light with a single atom in a high-finesse optical resonator. The strong coupling of the atom to the cavity field induces a genuine quantum mechanical nonlinearity, several orders of magnitude larger than for usual macroscopic media. This produces observable quadrature squeezing with an excitation beam containing on average only two photons per system lifetime. In sharp contrast to the emission of single photons, the squeezed light stems from the quantum coherence of photon pairs emitted from the system. The ability of a single atom to induce strong coherent interactions between propagating photons opens up new perspectives for photonic quantum logic with single emitters

Low Reynolds number hydrodynamics of asymmetric, oscillating dumbbell pairs

description: Active dumbbell suspensions constitute one of the simplest model system for collective swimming at low Reynolds number. Generalizing recent work, we derive and analyze stroke-averaged equations of motion that capture the effective hydrodynamic far-field interaction between two oscillating, asymmetric dumbbells in three space dimensions. Time-averaged equations of motion, as those presented in this paper, not only yield a considerable speed-up in numerical simulations, they may also serve as a starting point when deriving continuum equations for the macroscopic dynamics of multi-swimmer suspensions. The specific model discussed here appears to be particularly useful in this context, since it allows one to investigate how the collective macroscopic behavior is affected by changes in the microscopic symmetry of individual swimmers.

description: The existence of magnetohydrodynamic mean-field alpha^2-dynamos with spherically symmetric, isotropic helical turbulence function alpha is related to a non-self-adjoint spectral problem for a coupled system of two singular second order ordinary differential equations. We establish global estimates for the eigenvalues of this system in terms of the turbulence function alpha and its derivative alpha'. They allow us to formulate an anti-dynamo theorem and a non-oscillation theorem. The conditions of these theorems, which again involve alpha and alpha', must be violated in order to reach supercritical or oscillatory regimes.

Modelling the effects of landscape, behaviour, and population on bumble bee crop pollination services

description: Experimental and observational studies have shown that wildflower enhancements near crops can, but may not always, increase the pollination services that wild bees provide to the crops. However, the effects of spatial landscape structure, behavioural mechanisms, and wild bee population growth on pollination services are not well understood. Bee behaviours and crop pollination services are generally studied in isolation from one another. The majority of field studies that study pollination services have focused on counting pollinator populations rather than quantifying the number of flowers visited or providing other measures of crop specific pollination services, while behavioural studies focus on the behaviours of bees and do not consider their effects in pollinating flowers. Most modelling-based studies focus on how the wildflower plantings affect bee populations or provide very general indicators of pollination services, such a bee densities. In this thesis, I take an individual based modelling approach, developing a model that uses wild bumble bee flight patterns and foraging behaviour, incorporates memory, and allows for flower type preference, to measure bumble bee visits to flowers. I additionally use the Bee-Steward model to introduce the effect of population dynamics, and develop a Markov chain model to explore parameter estimation and the pitfalls that arise when attempting to fit models when data are scant. With these models, I simulate and analyze bumble bee movement and flower visits across simple landscapes with a single crop field and a single wildflower enhancement, as well as larger more complex landscapes with randomly generated crop fields and areas of wild flowers. I find that the spatial structure of the landscape has a significant effect on the pollination services delivered to the crops, that the mechanism by which bees select foraging sites can have a significant effect on crop pollination services, and that population growth can be responsible for increased pollination services, even in the absence of any changes in individual bee foraging behaviour.
