description: Abstract – Far from having lost centrality, the manual is still one of the most important teaching tools today. The aim of this article is not only to understand if and how much teachers use the manual, but also the criteria by which they choose the textbooks, as well as the ability to distance themselves from it to build their own course independently. If competency-based teaching on the one hand, and the presence of students with a multiple cultural background on the other, called for a renewal of teaching practices, how have these changes been received and implemented by teachers in the classroom? How did this affect the choice and use of textbooks? Through a case study - the teachers of the secondary school of the municipality of Genoa - we will try to understand these factors, taking into account training as an essential instrument not only for the acquisition of intercultural skills, but also for a critical choice and use of textbooks. Riassunto – Lungi dall’aver perso di centralità, il manuale è ancora oggi uno degli strumenti didattici più importanti. Obiettivo del presente articolo è non solo di comprendere se e quanto gli insegnanti utilizzino il manuale, ma anche i criteri in base ai quali essi scelgono i libri di testo, nonché la capacità di distanziarsene per costruire il proprio corso in modo autonomo. Se la didattica per competenze da un lato, e la presenza di studenti con un background culturale plurimo dall’altro, ha chiesto un rinnovamento delle pratiche di insegnamento, come tali cambiamenti sono stati recepiti e messi in atto dagli insegnanti in classe? In che modo ciò ha condizionato la scelta e l’uso dei libri di testo? Attraverso un case study – gli insegnanti della scuola secondaria del comune di Genova – si tenterà di comprendere tali fattori, tenendo conto della formazione quale strumento imprescindibile non solo per l’acquisizione di competenze interculturali, ma anche per una scelta e un uso critico dei libri di testo. Keywords – textbooks, teaching practices, intercultural skills, teacher training, teaching tools Parole chiave – manuali, pratiche di insegnamento, competenze interculturali, formazione degli insegnanti, strumenti didattici

description: Abstract – Is the trainer an educator? Is he/she aware of his/her role? Does he/she know the meaning of the term education? This paper intends to open a new line of research within a wide pedagogical literature which dealt with the educational role of the trainer, through the hermeneutic analysis of two focus groups conducted on a group of trainers living in the Lazio region, aged between 25 and 40. The homogeneous groups, chosen through a reasoned choice sampling, differ only because the components of the first group hold a Motor Science Degree while the others do not. The aim is to verify whether attending teaching courses of Didactic, Pedagogy and Special Pedagogy during the University course produces differences in determining the meaning of education. Such meaning is considered necessary to guide a conscious and intentional educational practice. The results reaffirm the difference between the groups and underline that a real educational activity in the youth sports field requires adequate preparation of the operators. Riassunto – L’allenatore è un educatore? È consapevole del suo ruolo? Conosce il significato del termine educazione? Questo saggio intende aprire una nuova pista di ricerca in una vasta letteratura pedagogica che si è occupata del ruolo educativo dell’allenatore, attraverso l’analisi ermeneutica di due focus group condotti su un gruppo di allenatori residenti nel Lazio, di età compresa tra i 25 ed i 40 anni. I gruppi omogenei, scelti attraverso un campionamento a scelta ragionata, si differenziano solo per il possesso della Laurea in Scienze motorie (primo gruppo) e assenza di essa (secondo gruppo). Questo per verificare se l’aver frequentato i corsi di insegnamento di Didattica, Pedagogia e Pedagogia speciale nel percorso universitario produca differenze nella determinazione del significato di educazione. Significato che si ritiene necessario per orientare una pratica educativa consapevole ed intenzionale. I risultati ribadiscono la differenza tra i gruppi e sottolineano che un vero lavoro educativo nel campo sportivo giovanile necessita di una adeguata preparazione degli operatori.

Θεωρητικές μελέτες έχουν δείξει ότι ο σχεδιασμός είναι πολύ αποτελεσματικός, επειδή μια μέση επίδραση μόνο 200 Kg μπορεί να παράγει 90 W ενέργειας. Δηλαδή, το ποσοστό ισχύς που παράγεται είναι πολύ σημαντικό, εφόσον αρκεί για να καλύψει μια διαδρομή φωτός 70W.
Covid-19 e nuove povertà. Esiti informalmente educativi della pandemia

description: Abstract – The pandemic of Covid-19 brings some new elements on the social scenario. These new elements are invalidating consolidated convictions and interpretations of our daily life. However, the pandemic, sometimes, proposes itself as something that falsely opens new scenarios. In fact, thanks to this emergency situation (expertly exploited), the pre-existent neoliberal social structures seem to obtain legitimacy rather than critics. However, over the time, even before this pandemic, these neoliberal structures have produced a precarious widespread culture, social vulnerability and multiple processes of impoverishment. This essay proposes a pedagogical reading of some of these educational cultural continuities, trying to show the consequences in terms of (singular and collective) learnings which could influence the lives in the territories and that could strength and widely expose to some situations of poverty. Riassunto – La pandemia di Covid-19 sta portando sulla scena sociale elementi di novità, che stanno invalidando convinzioni e interpretazioni consolidate della nostra vita quotidiana. Tuttavia, si sta proponendo anche come un qualcosa che, in alcuni casi, fintamente sta aprendo nuovi scenari. Sull’onda emergenziale (sapientemente sfruttata), infatti, sembrano trovare legittimazione, piuttosto che critiche, gli assetti economico-sociali neoliberisti preesistenti, che hanno nel tempo prodotto una cultura diffusa precarizzante, favorente, già prima della pandemia, vulnerabilità sociale e processi di impoverimento molteplici. Il saggio propone una lettura pedagogica di alcune di queste continuità culturali educanti, provando a leggerne le conseguenze in termini di apprendimenti (singolari e collettivi), condizionanti le vite nei territori, rafforzanti ed esponenti in maniera diffusa a situazioni di povertà.

description: We examine the star formation rates (SFRs) of galaxies in a redshift slice encompassing the z=0.834 cluster RX J0152.7-1357. We used a low-dispersion prism in the Inamori Magellan Areal Camera and Spectrograph (IMACS) to identify galaxies with z<23.3 AB mag in diverse environments around the cluster out to projected distances of ~8 Mpc from the cluster center. We utilize a mass-limited sample (M>2x10^{10} M_sun) of 330 galaxies that were imaged by Spitzer MIPS at 24 micron to derive SFRs and study the dependence of specific SFR (SSFR) on stellar mass and environment. We find that the SFR and SSFR show a strong decrease with increasing local density, similar to the relation at z~0. Our result contrasts with other work at z~1 that find the SFR-density trend to reverse for luminosity-limited samples. These other results appear to be driven by star-formation in lower mass systems (M~10^{10} M_sun). Our results imply that the processes that shut down star-formation are present in groups and other dense regions in the field. Our data also suggest that the lower SFRs of galaxies in higher density environments may reflect a change in the ratio of star-forming to non-star-forming galaxies, rather than a change in SFRs. As a consequence, the SFRs of star-forming galaxies, in environments ranging from small groups to clusters, appear to be similar and largely unaffected by the local processes that truncate star-formation at z~0.8.

Tα Glucagon like-peptide1 ανάλογα (GLP-1RAs), είναι μια σχετικά νέα και πολλά υποσχόμενη κατηγορία αντι-υπεργλυκαιμικών φαρμάκων. Tα GLP-1 εκτός από τη μείωση της γλυκόζης στο αίμα, φαίνεται να έχουν επιπρόσθετες πλειοτροπικές ιδιότητες, μεταξύ των οποίων και ευεργετικές σκελετικές επιδράσεις αν και οι υποκείμενοι μηχανισμοί δεν είναι πλήρως κατανοητοί. Ο στόχος αυτής της συστηματικής επισκόπησης ήταν να συνοψίσει τις τρέχουσες ενδείξεις σχετικά με τους GLP-1RAs και την επίδρασή τους στον μεταβολισμό των οστών και τον κίνδυνο κατάγματος.

Από τα άρθρα που περιλαμβάνονται οι συνολικές μελέτες που πραγματοποιήθηκαν σε ζώα έδειξαν ευεργετικές σκελετικές επιδράσεις των GLP-1RAs σε αντίθεση με αυτά που παρατηρήθηκαν στις μελέτες που πραγματοποιήθηκαν σε ανθρώπους όπου αυτοί οι παράγοντες δεν έχουν καμία επίδραση στην οστική πυκνότητα των οστών και στους δείκτες οστικής ανακατασκευής. Επιπλέον, αποδείχθηκε ότι η χρήση των GLP-1 αναλόγων δεν συσχετίστηκε με κίνδυνο κατάγματος σε σύγκριση με τη χρήση άλλων αντι-διαβητικών φαρμάκων. Τα ευρήματα αυτής της συστηματικής ανασκόπησης έχουν δείξει την ουδέτερη επίδραση των αγωνιστών GLP-1 στην οστική πυκνότητα.

description: We study the electronic structure of the junctions between a single graphene layer and carbon nanotubes, using a tight-binding model and the continuum theory based on Dirac fermion fields. The latter provides a unified description of different lattice structures with curvature, which is always localized at six heptagonal carbon rings around each junction. When these are evenly spaced, we find that it is possible to curve the planar lattice into armchair (6n,6n) as well as zig-zag (6n,0) nanotubes. We show that the junctions fall into two different classes, regarding the low-energy electronic behavior. One of them, constituted by the junctions made of the armchair nanotubes and the zig-zag (6n,0) geometries when n is a multiple of 3, is characterized by the presence of two quasi-bound states at the Fermi level, which are absent for the rest of the zig-zag nanotubes. These states, localized at the junction, are shown to arise from the effective gauge flux induced by the heptagonal carbon rings, which has a direct reflection in the local density of states around the junction. Furthermore, we also analyze the band structure of the arrays of junctions, finding out that they can also be classified into two different groups according to the low-energy behavior. In this regard, the arrays made of armchair and (6n,0) nanotubes with n equal to a multiple of 3 are characterized by the presence of a series of flat bands, whose number grows with the length of the nanotubes. We show that such flat bands have their origin in the formation of states confined to the nanotubes in the array. This is explained in the continuum theory from the possibility of forming standing waves in the mentioned nanotube geometries, as a superposition of modes with opposite momenta and the same quantum numbers under the C_6v symmetry of the junction.

Conjugate natural convection between two concentric spheres.
Creators: name: Lau, Meng Hooi
Publisher: name: University of British Columbia
Year: 2011

description: This work considers the conjugate convective heat transfer between a sphere containing heat sources and a concentric envelope maintained at a specified constant temperature. The space between the two is filled with an essentially incompressible fluid. Steady, laminar and rotationally symmetrical free convection is assumed to take place over the gap width and conduction is the sole transport mechanism considered inside the core. Two limiting cases, of an inner sphere of infinitely large relative heat conductivity, leading to an isothermal core to fluid interface; and of the converse case of small conductivity leading to a constant flux interface are considered separately. The analysis of heat transport leads to the solution of the governing equations through regular perturbation expansions with the Grashof number as main parameter. The ratio of conductivities, radius ratio and Prandtl number appear as secondary parameters. Streamlines, isovorticity curves and isotherms are obtained for various combinations of the parameters. The velocity distribution is determined and both local and overall values of the Nusselt number are obtained. A flow visualization test was undertaken and the core surface temperature distribution was determined experimentally. Reasonable qualitative agreement with the analysis is found.

description: We identify SDSS J130033.48+590407.0 as a common proper motion companion to the well-studied DA white dwarf PG 1258+593 (GD322). The system lies at a distance of 68 +/- 3 pc, where the angular separation of 16.1 +/- 0.1 arcsec corresponds to a minimum binary separation of 1091 +/- 7 AU. SDSS J1300+5904 is a cool (Teff = 6300 +/- 300K) magnetic white dwarf (B ~ 6 MG). PG 1258+593 is a hydrogen-rich (DA) white dwarf with Teff=14790 +/- 77 K and log(g) = 7.87 +/- 0.02. Using the white dwarf mass-radius relation implies the masses of SDSS J1300+5904 and PG 1258+593 are 0.54 +/- 0.06 Msun and 0.54 +/- 0.01 Msun, respectively, and therefore a cooling age difference of 1.67 +/- 0.05 Gyr. Adopting main-sequence life times from stellar models, we derive an upper limit of 2.2 Msun for the mass of the progenitor of PG 1258+593. A plausible range of initial masses is 1.4 - 1.8 Msun for PG 1258+593 and 2 - 3 Msun for SDSS J1300+5904. Our analysis shows that white dwarf common proper motion binaries can potentially constrain the white dwarf initial-final mass relation and the formation mechanism for magnetic white dwarfs. The magnetic field of SDSS J1300+5904 is consistent with an Ap progenitor star. A common envelope origin of the system cannot be excluded, but requires a triple system as progenitor.

Graphical tests for the absolute stability of multivariable nonlinear systems.
Creators: name: Lau, Jackson
Publisher: name: University of British Columbia
Year: 2011

description: Three graphical methods, similar to Popov's approach, are derived to test a stability criterion for a general class of multivariable nonlinear feedback systems. Various simplifications of these methods are then derived for four particular classes of system: the series system, the parallel system, the internal feedback system, and the symmetric system. These stability tests may be applied to active networks that consist of passive linear time-invariant elements and many nonlinear controlled sources. It is further shown that certain special network structures may be represented as one of the four particular classes of system.

description: The Magellanic Clouds offer a unique variety of star forming regions seen as bright nebulae of ionized gas, related to bright young stellar associations. Nowadays, observations with the high resolving efficiency of the Hubble Space Telescope allow the detection of the faintest infant stars, and a more complete picture of clustered star formation in our dwarf neighbors has emerged. I present results from our studies of the Magellanic Clouds, with emphasis in the young low-mass pre-main sequence populations. Our data include imaging with the Advanced Camera for Surveys of the association LH~95 in the Large Magellanic Cloud, the deepest observations ever taken with HST of this galaxy. I discuss our findings in terms of the Initial Mass Function, which we constructed with an unprecedented completeness down to the sub-solar regime, as the outcome of star formation in the low-metallicity environment of the LMC.

description: We report the results of a study of the rest-frame UV spectrum of the Cosmic Eye, a luminous Lyman break galaxy at z=3.07331 gravitationally lensed by a factor of 25. The spectrum, recorded with the ESI spectrograph on the Keck II telescope, is rich in absorption features from the gas and massive stars in this galaxy. The interstellar absorption lines are resolved into two components of approximately equal strength and each spanning several hundred km/s in velocity. One component has a net blueshift of -70 km/s relative to the stars and H II regions and presumably arises in a galaxy-scale outflow similar to those seen in most star-forming galaxies at z = 2-3. The other is more unusual in showing a mean redshift of +350 km/s relative to the systemic redshift; possible interpretations include a merging clump, or material ejected by a previous star formation episode and now falling back onto the galaxy, or more simply a chance alignment with a foreground galaxy. In the metal absorption lines, both components only partially cover the OB stars against which they are being viewed. We tentatively associate the redshifted component with the strong damped Lyman alpha line, indicative of a column density N(H I) = (3.0 +/- 0.8) x 10(21) atoms/cm2, and propose that it provides the dust `foreground screen' responsible for the low ratio of far-infrared to UV luminosities of the Cosmic Eye. Compared to other well-studied examples of strongly lensed galaxies, we find that the young stellar population of the Cosmic Eye is essentially indistinguishable from those of the Cosmic Horseshoe and MS 1512-cB58, while the interstellar spectra of all three galaxies are markedly different, attesting to the real complexity of the interplay between starbursts and ambient interstellar matter in young galaxies (abridged).

description: Abstract – Today more than in the past, topics and issues related to sustainability pose challenges to the world of education and schools, wherein teachers are “agents of change”. With the Italian Law n. 92 of August 20th, 2019 reintroducing civic education in schools, the 2030 Agenda becomes central in the training and considerations of future generations. Is the Italian School system ready to promote the culture of sustainability in a broad sense and to contribute to it? What is teachers’ knowledge around sustainability and how much do educators feel to be trained on the 2030 Agenda? To answer these questions, an on-line survey has been administered to a sample of 341 kindergarten and Primary School teachers permanently hired in the last three years in the Province of Bari, Italy. It has been found that the majority of teachers knows the contents of the 2030 Agenda and believe its knowledge to be relevant for the personal and professional growth. However, that knowledge was not always acquired through the university or on-the-job training, and necessarily needs to be complemented by a deeper understanding of the methods, educational and assessment tools for sustainability. Riassunto – I temi e le questioni della sostenibilità rappresentano, oggi più che in passato, una vera e propria sfida per il mondo dell’educazione e della scuola all’interno della quale i docenti sono “agenti di cambiamento”. Con la Legge n. 92 del 20 agosto 2019 che reintroduce l’educazione civica nelle scuole, l’Agenda 2030 diviene tema centrale per la formazione e la riflessione delle future generazioni. La Scuola italiana è pronta a promuovere e contribuire ad una cultura della sostenibilità diffusa? Quanto gli insegnanti conoscono la sostenibilità e quanto ritengono di essere stati formati ai temi dell’Agenda 2030? Attraverso un questionario online somministrato a un campione di 341 docenti di scuola dell’Infanzia e Primaria assunti a tempo indeterminato negli ultimi tre anni nella provincia di Bari, è stato possibile rilevare che la maggior parte dei docenti conosce i contenuti dell’Agenda 2030 e ritiene tali conoscenze importanti per la propria crescita personale e professionale. Si tratta però di conoscenze non sempre acquisite attraverso la formazione universitaria o in servizio e necessitanti di una maggiore attenzione ai metodi e agli strumenti di educazione e valutazione per la sostenibilità.

description: Spectrum sensing is one of the enabling functionalities for cognitive radio (CR) systems to operate in the spectrum white space. To protect the primary incumbent users from interference, the CR is required to detect incumbent signals at very low signal-to-noise ratio (SNR). In this paper, we present a spectrum sensing technique based on correlating spectra for detection of television (TV) broadcasting signals. The basic strategy is to correlate the periodogram of the received signal with the a priori known spectral features of the primary signal. We show that according to the Neyman-Pearson criterion, this spectral correlation-based sensing technique is asymptotically optimal at very low SNR and with a large sensing time. From the system design perspective, we analyze the effect of the spectral features on the spectrum sensing performance. Through the optimization analysis, we obtain useful insights on how to choose effective spectral features to achieve reliable sensing. Simulation results show that the proposed sensing technique can reliably detect analog and digital TV signals at SNR as low as -20 dB.

Flare-less long Gamma-ray Bursts and the properties of their massive star progenitors

description: While there is mounting evidence that long Gamma-Ray Bursts (GRBs) are associated with the collapse of massive stars, the detailed structure of their pre-supernova stage is still debatable. Particularly uncertain is the degree of mixing among shells of different composition, and hence the role of magnetic torques and convection in transporting angular momentum. Here we show that early-time afterglow observations with the Swift satellite place constraints on the allowed GRB pre-supernova models. In particular, they argue against pre-supernova models in which different elemental shells are unmixed. These types of models would produce energy injections into the GRB engine on timescales between several hundreds of seconds to a few hours. Flaring activity has {\em not} been observed in a large fraction of well-monitored long GRBs. Therefore, if the progenitors of long GRBs have common properties, then the lack of flares indicates that the massive stars which produce GRBs are mostly well mixed, as expected in low-metallicity, rapidly rotating massive stars.

Renormalized Landau Levels and Particle-Hole Symmetry in Graphene

description: In this proceedings paper we report on a calculation of graphene's Landau levels in a magnetic field. Our calculations are based on a self-consistent Hartree-Fock approximation for graphene's massless-Dirac continuum model. We find that because of graphene's chiral band structure interactions not only shift Landau-level energies, as in a non-relativistic electron gas, but also alter Landau level wavefunctions. We comment on the subtle continuum model regularization procedure necessary to correctly maintain the lattice-model's particle hole symmetry properties.

description: A preconditioning theory is presented which establishes sufficient conditions for multiplicative and additive Schwarz algorithms to yield self-adjoint positive definite preconditioners. It allows for the analysis and use of non-variational and non-convergent linear methods as preconditioners for conjugate gradient methods, and it is applied to domain decomposition and multigrid. It is illustrated why symmetrizing may be a bad idea for linear methods. It is conjectured that enforcing minimal symmetry achieves the best results when combined with conjugate gradient acceleration. Also, it is shown that absence of symmetry in the linear preconditioner is advantageous when the linear method is accelerated by using the Bi-CGstab method. Numerical examples are presented for two test problems which illustrate the theory and conjectures.

description: We present high-speed optical photometry of the anomalous X-ray pulsar 1E 1048.1-5937 obtained with ULTRACAM on the 8.2-m Very Large Telescope in June 2007. We detect 1E 1048.1-5937 at a magnitude of i'=25.3+/-0.2, consistent with the values found by Wang et al. (2008) and hence confirming their conclusion that the source was approximately 1 mag brighter than in 2003-2006 due to an on-going X-ray flare that started in March 2007. The increased source brightness enabled us to detect optical pulsations with an identical period (6.458 s) to the X-ray pulsations. The rms pulsed fraction in our data is 21+/-7%, approximately the same as the 2-10 keV X-ray rms pulsed fraction. The optical and X-ray pulse profiles show similar morphologies and appear to be approximately in phase with each other, the latter lagging the former by only 0.06+/-0.02 cycles. The optical pulsations in 1E 1048.1-5937 are very similar in nature to those observed in 4U 0142+61. The implications of our observations for models of anomalous X-ray pulsars are discussed.

description: We present a comparison of the noncommutative field theories built using two different star products: Moyal and Wick-Voros (or normally ordered). For the latter we discuss both the classical and the quantum field theory in the quartic potential case, and calculate the Green's functions up to one loop, for the two and four points cases. We compare the two theories in the context of the noncommutative geometry determined by a Drinfeld twist, and the comparison is made at the level of Green's functions and S-matrix. We find that while the Green's functions are different for the two theories, the S-matrix is the same in both cases, and is different from the commutative case.

Contribution to the Extragalactic Gamma-ray Background from the Cascades of Very-high Energy Gamma Rays from Blazars

description: As very high energy (VHE) photons propagate through the extragalactic background light (EBL), they interact with the soft photons and initiate electromagnetic cascades of lower energy photons and electrons. The collective intensity of a cosmological population emitting at VHEs will be attenuated at the highest energies through interactions with the EBL and enhanced at lower energies by the resulting cascade. We calculate the cascade radiation created by VHE photons produced by blazars and investigate the effects of cascades on the collective intensity of blazars and the resulting effects on the extragalactic gamma-ray background. We find that cascade radiation greatly enhances the collective intensity from blazars at high energies before turning over due to attenuation. The prominence of the resulting features depends on the blazar gamma-ray luminosity function, spectral index distribution, and the model of the EBL. We additionally calculate the cascade radiation from the distinct spectral sub-populations of blazars, BL Lacertae (BL Lacs) objects and flat-spectrum radio quasars (FSRQs), finding that the collective intensity of BL Lacs is considerably more enhanced by cascade radiation than that of the FSRQs. Finally, we discuss the implications that this analysis and upcoming Fermi observations could have for the nature of the EBL, the evolution of blazars, blazar spectra, and other sources of gamma-ray radiation.

Estimating Black Hole Masses in Triaxial Galaxies

description: Most of the super massive black hole mass estimates based on stellar kinematics use the assumption that galaxies are axisymmetric oblate spheroids or spherical. Here we use fully general triaxial orbit-based models to explore the effect of relaxing the axisymmetric assumption on the previously studied galaxies M32 and NGC 3379. We find that M32 can only be modeled accurately using an axisymmetric shape viewed nearly edge-on and our black hole mass estimate is identical to previous studies. When the observed 5 degrees kinematical twist is included in our model of NGC 3379, the best shape is mildly triaxial and we find that our best-fitting black hole mass estimate doubles with respect to the axisymmetric model. This particular black hole mass estimate is still within the errors of that of the axisymmetric model and consistent with the M-sigma relationship. However, this effect may have a pronounced impact on black hole demography, since roughly a third of the most massive galaxies are strongly triaxial.

description: In this paper, we give a complete set of finite type string link invariants of degree <5. In addition to Milnor invariants, these include several string link invariants constructed by evaluating knot invariants on certain closure of (cabled) string links. We show that finite type invariants classify string links up to C_k-moves for k<6, which proves, at low degree, a conjecture due to Goussarov and Habiro. We also give a similar characterization of finite type concordance invariants of degree <6.
