description: We consider moments of the return times (or first hitting times) in a discrete time discrete space Markov chain. It is classical that the finiteness of the first moment of a return time of one state implies the finiteness of the first moment of the first return time of any other state. We extend this statement to moments with respect to a function $f$, where $f$ satisfies a certain, best possible condition. This generalizes results of K. L. Chung (1954) who considered the functions $f(n)=n^p$ and wondered "[...] what property of the power $n^p$ lies behind this theorem [...]" (see Chung (1967), p. 70). We exhibit that exactly the functions that do not increase exponentially -- neither globally nor locally -- fulfill the above statement.

description: We review recent claims of the existence of deeply bound kaonic states in nuclei. Also we study in details the (K-,p) reaction on C12 with 1 GeV/c momentum kaon beam, based on which a deep kaon nucleus optical potential was claimed in [1]. In our Monte Carlo simulation of this reaction we include not only the quasi-elastic K- p scattering, as in [1], but also K- absorption by one and two nucleons followed by the decay of the hyperon in pi N, which can also produce strength in the region of interest. The final state interactions in terms of multiple scattering of the K-, p and all other primary particles on their way out of the nucleus is also considered. We will show that all these additional mechanisms allow us to explain the observed spectrum with a "standard" shallow kaon nucleus optical potential obtained in chiral models. [1] T.

description: We propose a new permanent magnetic lattice for creating periodic arrays of Ioffe-Pritchard permanent magnetic microtraps for holding and controlling ultracold atoms and Bose-Einstein condensates (BECs). Lattice can be designed on thin layer of magnetic films such as $Tb_6$$Gd_10$$Fe_{80}$$Co_4$. In details, we investigate single layer and two crossed layers of sawtooth magnetic patterns with thicknesses of 50 and 500nm respectively with a periodicity of 1$μ$m. Trap depth and frequencies can be changed via an applied bias field to handle tunneling rates between lattice sites. We present analytical expressions and using numerical calculations show that this lattice has non-zero potential minima to avoid majorana spin flips. One advantage of this lattice over previous ones is that it is easier to manufacture.

Secondary science teachers' views on climate change education in British Columbia
Creators: name: Shim, Jiyoung
Publisher: name: University of British Columbia
Year: 2021

description: As effects of climate change continue to manifest in serious impacts on human and non-human health and well-being globally, there is the urgent need for research into this climate crisis through an education lens. This necessarily implicates how teachers understand the issues involving climate change and the nature of climate change discourses in which they engage their students. Hence this study investigated secondary school science teachers’ views on climate change and how it is framed or should be framed within secondary school science curriculum and instruction. Investigating science teachers’ views is very important due to the fact that climate change is not sufficiently addressed in many secondary school science curricula and especially in the British Columbia Ministry of Education curriculum. Thus, by employing a qualitative interview method approach, six practising BC secondary science teachers were recruited to participate in a study that sought their views on climate change through a series of semi-structured interviews. The interview data were analysed resulting in key themes that characterised the teachers’ understanding of climate change and related issues and how they taught it. The key themes included: 1) participating teachers’ perspectives on climate change as shaped by their own experiences, their students and society; 2) participating teachers’ assessment of the current BC secondary science curriculum to be lacking on the methodology to teach and structure climate change content; 3) participating teachers’ views that enhancing student experiential and propositional knowledge on climate is the best way to effect change; and 4) participating teachers’ views that climate change topic is best understood by the students when it is taught through place-based pedagogies with an interdisciplinary approach of which science is a part. The study’s findings have implications on how climate change topic and discourses can be framed in the local BC curricula including secondary school science curriculum and instruction.

description: The injection of photoelectrons in a gaseous or liquid sample is a widespread technique to produce a cold plasma in a weakly--ionized system in order to study the transport properties of electrons in a dense gas or liquid. We report here the experimental results of photoelectron injection into dense argon gas at the temperatureT=142.6 K as a function of the externally applied electric field and gas density. We show that the experimental data can be interpreted in terms of the so called Young-Bradbury model only if multiple scattering effects due to the dense environment are taken into account when computing the scattering properties and the energetics of the electrons.

description: Nel mio LD ho trattato l’uso divergente dell’oggetto nel gioco simbolico, ossia come un oggetto può essere trasformato in qualcosa di completamente diverso da sé stesso nella fantasia del bambino mentre sta inscenando un gioco ambientato in una situazione immaginaria, per es. fare finta di giocare alle corse automobilistiche (la situazione immaginaria) con un bastone di legno (l’uso divergente dell’oggetto). Per ricavare dati utili alla mia ricerca ho adottato un sistema di osservazione neutra, i bambini trovavano gli oggetti da me selezionati per la ricerca nel salone della loro sezione e potevano giocarci o meno durante le loro sessioni di gioco libero. I risultati hanno mostrato che oggetti come un manico di scopa e una stoffa azzurra stimolano i bambini a giocare molto più che altri oggetti come un bastone di legno o un bambolotto e che i modi di utilizzare i primi due oggetti sono molteplici. Questi due oggetti sono stati sufficienti per far mettere in scena decine di giochi diversi e tenere i bambini occupati per molto tempo in intere sessioni di gioco senza che essi abbiano mai mostrato segni di noia.

description: An experimental photochemistry study involving gas- and solid-phase amino acids (glycine, DL-valine, DL-proline) and nucleobases (adenine and uracil) under soft X-rays was performed. The aim was to test the molecular stabilities of essential biomolecules against ionizing photon fields inside dense molecular clouds and protostellar disks analogs. In these environments, the main energy sources are the cosmic rays and soft X-rays. The measurements were taken at the Brazilian Synchrotron Light Laboratory (LNLS), employing 150 eV photons. In-situ sample analysis was performed by Time-of-flight mass spectrometer (TOF-MS) and Fourier transform infrared (FTIR) spectrometer, for gas- and solid- phase analysis, respectively. The half-life of solid phase amino acids, assumed to be present at grain mantles, is at least 3E5 years and 3E8 years inside dense molecular clouds and protoplanetary disks, respectively. We estimate that for gas-phase compounds these values increase one order of magnitude since the dissociation cross section of glycine is lower at gas-phase than at solid phase for the same photon energy. The half-life of solid phase nucleobases is about 2-3 orders of magnitude higher than found for amino acids. The results indicate that nucleobases are much more resistant to ionizing radiation than amino acids. We consider these implications for the survival and transfer of biomolecules in space environments.

description: We study pion condensation at zero temperature in a hard-wall holographic model of hadrons with isospin chemical potential. We find that the transition from the hadronic phase to the pion condensate phase is first order except in a certain limit of model parameters. Our analysis suggests that immediately across the phase boundary the condensate acts as a stiff medium approaching the Zel'dovich limit of equal energy density and pressure.

Aqua Buna: un percorso per valorizzare l’acqua di rubinetto di Bergamo

description: In Italia esiste obbligo da parte degli acquedotti di fornire acqua potabile. Nonostante ciò siamo il paese in Europa che consuma la maggior quantità di acqua in bottiglia. Esiste infatti una diffidenza diffusa nei confronti dell’acqua di rubinetto. La mia città è Bergamo, un Comune ai piedi delle prealpi orobiche. È da lì che proviene l’acqua sorgiva, fresca, gradevole al gusto e disponibile dappertutto. Perché non comunicare visivamente al cittadino queste qualità dell’acqua sensibilizzandolo al consumo? Fino ad oggi lo sforzo dedicato a questo messaggio non è stato sufficiente a superare la diffidenza. Questa considerazione mi ha stimolato a progettare una campagna volta al consumo dell’acqua di rubinetto iniziando proprio dal Comune di Bergamo. Per la tipologia di comunicazione, ho deciso di agire in maniera sottile presentando l’acqua di Bergamo come un’opportunità valida, economica e sempre disponibile. Ho messo in risalto la purezza unita al sapore gradevole, propria dell’acqua di Bergamo, mirando a colpire al cuore i Bergamaschi.

description: We investigate the properties of time reversibility of a soliton gas, originating from a dispersive regularization of a shock wave, as it propagates in a strongly disordered environment. An original approach combining information measures and spin glass theory shows that time reversal focusing occurs for different replicas of the disorder in forward and backward propagation, provided the disorder varies on a length scale much shorter than the width of the soliton constituents. The analysis is performed by starting from a new class of reflectionless potentials, which describe the most general form of an expanding soliton gas of the defocusing nonlinear Schroedinger equation.

biologia umana
essenziale
pensare sistemico
sguardo docente

description: Qual è la cosa più importante quando si parla di insegnamento? Quale bagaglio conta davvero per i nostri giovani? Siamo di fronte ad una società nuova: il sapere è alla portata di tutti e prolifera a gran velocità. In risposta a questo cambiamento, nasce l’idea di una didattica costruita su pochi ma unificanti concetti chiave in grado di selezionare e organizzare l’essenziale nel grande calderone della conoscenza scientifica. Lo scopo di questa ricerca è stato quello di progettare un percorso didattico in biologia umana mettendo al centro le idee chiave pensate per la scuola media e raccoglierne le implicazioni per il docente. 23 allievi tra i 13 e i 14 anni sono stati osservati e le loro sensazioni raccolte in un diario di bordo della docente. L’indagine è stata svolta secondo il metodo di ricercaazione, alternando momenti di intervento didattico con momenti di riflessione critica e riprogettazione. La sperimentazione con modelli si è rilevata una possibile conseguenza della progettazione, implicando dei limiti ma anche delle opportunità. I concetti chiave vanno identificati nelle attività che meglio si prestano senza forzature e senza perdere la spontaneità degli allievi. La ricerca dell’essenziale implica una ricerca più qualitativa dei contenuti piuttosto che quantitativa. È importante costruire questi concetti insieme alla classe e vedere questo approccio come un modo di pensare sistemico. Lo sguardo dell’allievo rimane per ora un ambito inesplorato per il quale confido in ulteriori indagini. Relatore: Daniele Milani. Materia: Scienze naturali.
Determination of strain limits for dimensioning polyurethane components

description: Within the scope of this contribution, a method for the determination of a strain limit for designing components made of elastomeric polyurethane systems is presented. The knowledge of a material-specific strain limit is essential for the structural-mechanical calculation of plastic components in the context of component design. Compared to a commonly used component design, based on a simplified dimensioning approach taking only linear viscoelastic deformations into account, the strain limit determined in this study allows an improved utilisation of lightweight construction potential in the dimensioning of technical components made of polyurethanes through the consideration of permissible nonlinear viscoelastic deformations. The test method comprises a sequence of quasi-static loading and unloading cycles, with a subsequent load-free recovery phase, allowing the relaxation of the viscoelastic forces. Standardised tensile and simple shear test specimens and a dynamic mechanical thermal analyser (DMTA) are used within the tests. The strain limit is determined by means of the so-called residual energy ratio, which is a characteristic quantity for the evaluation of hystereses of load–unload cycles. These hystereses are increasingly formed by deformations outside the range of linear viscoelastic deformations. The residual energy ratio relates the proportion of deformation energy recovered during unloading to the deformation work that is applied. In this contribution, the residual energy ratio is successfully used to detect a significant evolution of loss energy under increasing load and to correlate this transition to a characteristic strain. The latter is used as a dimensioning parameter for the design of components made of elastomeric polyurethane materials for quasi-static load cases. The determination of this strain limit is performed under consideration of the criterion of reversibility of deformation.

Architectures and learning algorithms for data-driven decision making
Creators: name: Hartford, Jason Siyanda
Publisher: name: University of British Columbia
Year: 2021

description: To design good policy, we need accurate models of how the decision makers that operate within a given system will respond to policy changes. For example, an economist reasoning about the design of an auction needs a model of human behavior in order to predict how changes to the auction design will be reflected in outcomes; or a doctor deciding on treatments needs a model of people's health responses under different treatments to select the best treatment policy. We would like to leverage the accuracy of modern deep learning approaches to estimate these models, but this setting brings two non-standard challenges. First, decision problems often involve reasoning over sets of items, so we need deep networks that reflect this structure. The first part of this thesis develops a deep network layer that reflects this structural assumption, and shows that the resulting layer is maximally expressive among parameter tying schemes. We then evaluate deep network architectures composed of these layers on a variety of decision problems from human decision making in a game theory setting, to algorithmic decision making on propositional satisfiability problems. The second challenge is that predicting the effect of policy changes involves reasoning about shifts in distribution: any policy change will, by definition, change the conditions under which decision makers operate. This violates the standard machine learning assumption that models will be evaluated under the same conditions as those under which they were trained (the ``independent and identically distributed'' data assumption). The second part of this thesis shows how we can train deep networks that make valid predictions of the results of such policy interventions, by adapting the classical causal inference method of instrumental variables. Finally, we develop methods that are robust to some violations of the instrumental variable assumptions in settings with multiple instrumental variables.

description: We consider the appearance of multiple scalar fields in SFT inspired non-local models with a single scalar field at late times. In this regime all the scalar fields are free. This system minimally coupled to gravity can be analyzed approximately or numerically. The main result of this note is the introduction of an exactly solvable model which obeys an exact solution in the cosmological context for the Friedmann equations and that reproduces the behavior expected from SFT in the asymptotic regime. Different applications of such a potential to multi-field cosmological models are discussed.

description: The performance of the Hybrid Monte Carlo algorithm is determined by the speed of sparse matrix-vector multiplication within the context of preconditioned conjugate gradient iteration. We study these operations as implemented for the fermion matrix of the Hubbard model in d+1 space-time dimensions, and report a performance comparison between a 2.66 GHz Intel Xeon E5430 CPU and an NVIDIA Tesla C1060 GPU using double-precision arithmetic. We find speedup factors ranging between 30-350 for d = 1, and in excess of 40 for d = 3. We argue that such speedups are of considerable impact for large-scale simulational studies of quantum many-body systems.

"Goin' to the chapel" or are we?: Wedding venues & the law in Ireland

description: Prior to the onset of the Covid-19 pandemic, upwards of 40,000 people got married in Ireland annually. Given that this number has fallen significantly in 2020 and 2021, the number of weddings celebrated in 2022 and thereafter will likely increase even further. The weddings industry is a small but increasingly recognised sector of Ireland’s wider economy with Irish weddings reported to cost, on average, €25,000.1 However, notwithstanding that it is of significant importance to many people every year, Irish weddings law – located in the Civil Registration Act 2004 (as amended) – has attracted scant academic attention to date.

Indutores de problematização aplicados a uma aula de antropologia e dilema moral emergente

Publisher: name: Escola Superior de Educação de Paula Frassinetti - CIPAF

Subjects: Antropologia; Problematização

description: Este artigo relata uma experiência ocorrida no âmbito do ensino de estudantes do curso de educação social que, após terem realizado uma investigação de cariz antropológica num bairro da cidade do Porto a partir do conceito de “não-lugares” de Marc Augé, continuavam sem “ver” e “reconhecer” os seus habitantes, permanecendo estes sem rosto e nome concretos nas transcrições e nos discursos destes estudantes. O problema da invisibilidade aqui abordado foi trabalhado em sala de aula a partir do modelo teórico da problematização e aplicado, neste caso, aos dilemas morais suscitados no espírito do professor quando se apercebeu da incapacidade dos estudantes em “verem” (= reconhecerem) os habitantes do bairro. O problemático surgiu quando esta experiência demonstrou que a formação humanista dos educadores sociais que se pretende alcançar ao longo do curso ainda não estava assumida. A partir desta constatação, e socorrendo-se do losango de problematização sugerido por Fabre & Musquer (2009), o docente optou por uma abordagem de ensino centrada numa epistemologia moral que realçasse as formas de olhar com indiferença ou eivadas de estereótipos ‘através de outrem’, sem levar em consideração o sujeito no seu estatuto de pessoa. Pretende futuramente retirar dos ferimentos morais (inconscientemente) infligidos pelos estudantes aos habitantes ‘invisíveis’ os princípios morais do conceito de reconhecimento que, para o ser, requer a aprendizagem de uma certa literacia moral, especialmente dos educadores sociais.

description: Marengo and the second author have developed in the last years a geometric model of social choice when this takes place among bundles of interdependent elements, showing that by bundling and unbundling the same set of constituent elements an authority has the power of determining the social outcome. In this paper we will tie the model above to tournament theory, solving some of the mathematical problems arising in their work and opening new questions which are interesting not only from a mathematical and a social choice point of view, but also from an economic and a genetic one. In particular, we will introduce the notion of u-local optima and we will study it from both a theoretical and a numerical/probabilistic point of view; we will also describe an algorithm that computes the universal basin of attraction of a social outcome in O(M^3 logM) time (where M is the number of social outcomes).

description: I present an extensible experimental design for optical continuous-variable cluster states of arbitrary size using four offline (vacuum) squeezers and six beamsplitters. This method has all the advantages of a temporal-mode encoding [Phys. Rev. Lett. 104, 250503], including finite requirements for coherence and stability even as the computation length increases indefinitely, with none of the difficulty of inline squeezing. The extensibility stems from a construction based on Gaussian projected entangled pair states (GPEPS). The potential for use of this design within a fully fault tolerant model is discussed.

description: Several experimental techniques have been introduced in recent years in attempts to measure spin transfer torque in magnetic tunnel junctions (MTJs). The dependence of spin torque on bias is important for understanding fundamental spin physics in magnetic devices and for applications. However, previous techniques have provided only indirect measures of the torque and their results to date for the bias dependence are qualitatively and quantitatively inconsistent. Here we demonstrate that spin torque in MTJs can be measured directly by using time-domain techniques to detect resonant magnetic precession in response to an oscillating spin torque. The technique is accurate in the high-bias regime relevant for applications, and because it detects directly small-angle linear-response magnetic dynamics caused by spin torque it is relatively immune to artifacts affecting competing techniques. At high bias we find that the spin torque vector differs markedly from the simple lowest-order Taylor series approximations commonly assumed.

L’uso del cinema di fiction: nell’insegnamento della storia

Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2016

description: La presente ricerca in ambito educativo vuole dimostrare l’efficacia dell’utilizzo delle fonti cinematografiche per l’insegnamento della Storia. Nello specifico la mia proposta di attività va inserita nel contesto di una classe al terzo anno delle scuole medie e, andrà letta, nell’ottica di presentare ai ragazzi tematiche molto complesse quali il razzismo, lo schiavismo e gli abusi umani verso altre porzioni di umanità. In relazione con la trattazione di tali tematiche ho deciso di sottoporre agli allievi la visione del film “Amistad” trattante, attraverso una ricostruzione di una vicenda realmente accaduta, la deportazione degli Africani verso il continente americano. In seguito ho proposto alla classe una serie di attività, che hanno permesso l’elaborazione di quanto visionato nel film, in relazione a fonti storiche, e di verificare l’acquisizione dei contenuti da parte dei ragazzi. La riflessione scaturita da tale approccio didattico mi ha portata a riflettere sul mio operato sia dal punto di vista didattico sia da quello educativo. Da un lato mi sono chiesta se un approccio del genere risultasse più interessante per gli allievi e, di conseguenza, gli rendesse più facile prestare la dovuta attenzione nel corso della lezione. Dall’altro lato mi sono interrogata chiedendomi se i concetti che realmente venivano trasmessi agli allievi fossero quelli che mi ero proposta di “far passare”. Le risposte a tali domande non hanno potuto che essere positive. Infatti ho notato in notevole incremento dell’attenzione da parte di tutti gli allievi ed una notevole partecipazione emotiva da parte della maggior parte della classe. Infine, presentando alcuni esercizi riguardanti tali tematiche, dopo una settimana dalla visione dello spezzone del film, ho potuto accertare che i ragazzi ricordavano ancora i concetti principali, senza bisogno di ore di studio, che avevano appreso nel corso della precedente lezione.

New Herbig Ae/Be stars confirmed via high-resolution optical spectroscopy

description: We present FEROS high-resolution (R~45000) optical spectroscopy of 34 Herbig Ae/Be star candidates with previously unknown or poorly constrained spectral types. Within the sample, 16 sources are positionally coincident with nearby (d<250 pc) star-forming regions (SFRs). All the candidates have IR excess. We determine the spectral type and luminosity class of the sources, derive their radial and rotational velocities, and constrain their distances employing spectroscopic parallaxes. We confirm 13 sources as Herbig Ae/Be stars and find one classical T Tauri star. Three sources are emission line early-type giants and may be Herbig Ae/Be stars. One source is a main-sequence A-type star. Fourteen sources are post-main-sequence giant and supergiant stars. Two sources are extreme emission-line stars. Most of the sources appear to be background stars at distances over 700 pc. We show that high-resolution optical spectroscopy is a crucial tool for distinguishing young stars from post-main sequence stars in samples taken from emission-line star catalogs based on low-resolution spectroscopy. Within the sample, 3 young stars (CD-38 4380, Hen 3-1145, and HD 145718) and one early-type luminosity class III giant with emission lines (Hen 3-416) are at distances closer than 300 pc and are positionally coincident with a nearby SFR. These 4 sources are likely to be nearby young stars and are interesting for follow-up observations at high-angular resolution. Furthermore, seven confirmed Herbig Ae/Be stars at d>700 pc (Hen 2-80, Hen 3-1121 N&S, HD 313571, MWC 953, WRAY 15-1435, and Th 17-35) are inside or close (<5') to regions with extended 8 micron continuum emission and in their 20' vicinity have astronomical sources characteristic of SFRs. These 7 sources are likely to be members of SFRs. These regions are attractive for future studies of their stellar content.

description: We study the formation of Faraday waves in an elongated Bose-Einstein condensate in presence of a one-dimensional optical lattice, where phonons are parametrically excited by modulating the radial confinement of the condensate. For very shallow optical lattices, phonons with a well-defined wave vector propagate along the condensate, as in the absence of the lattice, and we observe the formation of a Faraday pattern. By increasing the potential depth, the local sound velocity decreases and when it equals the condensate local phase velocity, the condensate becomes dynamically unstable and the parametric excitation of Faraday waves is suppressed.

description: The research is dedicated to the study of motives and imagery in R. Dahlâs fiction.Â  The motive and imagery analysis of short stories The Landlady, Skin, Lamb to the Slaughter as well as the analysis of stylistic devices was done. The study also includes the basic theoretical aspects of concepts âmotifâ and âimageâ and Dahlâs biography. As a result of the study, it was revealed that Dahlâs fiction is characterized by the usage of realistic and dark images, the major motif in his adult stories is murder. The presented results can be used in further research of R. Dahlâs fiction.
