description: We present two-dimensional fully-kinetic Particle-in-Cell simulations of decaying electromagnetic fluctuations. The computational box is such that wavelengths ranging from electron to ion gyroradii are resolved. The parameters used are realistic for the solar wind, and the ion to electron mass ratio is physical. The understanding of the dissipation of turbulent fluctuations at small scales is thought to be a crucial mechanism for solar wind acceleration and coronal heating. The computational results suggest that a power law cascade of magnetic fluctuations could be sustained up to scales of the electron Larmor radius and smaller. We analyse the simulation results in the light of the Vlasov linear theory, and we comment on the particle heating. The dispersion curves of lightly damped modes in this regime suggest that a linear mechanism could be responsible for the observed steepening of power spectra at electron scales, but a straightforward identification of turbulent fluctuations as an ensemble of linear modes is not possible

title: Anti-predator behaviour in UK tit species : information encoding, predator recognition, and individual variation
Creators: name: Carlson, Nora
Publisher: name: University of St Andrews
Year: 2017

description: To combat the ever-present threat of predation many species produce anti-predator vocalizations and behaviours (mobbing) designed to drive predators away. These vocalizations can encode a predator’s threat level, and many species within a community will eavesdrop on this information. To determine how prey species produce, use, and respond to anti-predator information and how individual, social, and phylogenetic factors of different species may influence this behaviour, I conducted a series of robotic-predator presentation and anti-predator vocalization playback experiments in the wild and lab. I predicted that UK Paridae would encode information the same as previously studied species. I found that UK Paridae encode predator information in different ways, and that neither phylogeny nor ecology explained the patterns of similarity in how different species encode predator threat in their calls. Flock structure appeared to affect how species encoded predator threat and while multiple species may be sources of information for familiar flock mates, only blue and great tits met the criteria to be community informants. As blue and great tits need prior experience to recognize novel predators and juvenile great tits avoid novel predators only after seeing adults mob them, tits may use mobbing calls to learn about novel predators. While they responded to mobbing calls, juvenile blue and great tits did not engage in mobbing behaviour although they appear capable of doing so. Furthermore, while individuals varied in their responses to aerial alarm calls this variation was not explained by either their proximity to the call nor their personality. In this close examination of how anti-predator vocalizations are produced and used by UK Paridae, I found variation in these signals. This challenges previous assumptions about how Paridae encode information, raising questions as to the sources of this variation.

description: The preparation of neutron-optical phase gratings with light-optical holography is reviewed. We compare the relevant concepts of i) Kogelnik's theory for Bragg diffraction of light by thick volume gratings, which can be used to analyze holographic gratings with both light and neutrons, and ii) the dynamical theory of neutron diffraction. Without going into mathematical detail, we intend to illuminate their correspondence. The findings are illustrated by analyzing data obtained from reconstruction of nanoparticle holographic gratings with both light and neutrons.

description: In previous works, we showed that the internal DLA cluster on \Z^d with t particles is a.s. spherical up to a maximal error of O(\log t) if d=2 and O(\sqrt{\log t}) if d > 2. This paper addresses "average error": in a certain sense, the average deviation of internal DLA from its mean shape is of constant order when d=2 and of order r^{1-d/2} (for a radius r cluster) in general. Appropriately normalized, the fluctuations (taken over time and space) scale to a variant of the Gaussian free field.

Un’orchestra di strumenti matematici: macchine matematiche, software di geometria dinamica e LIM nella scuola media

description: In questo lavoro di diploma è descritto l’uso intenzionale di più strumenti (orchestrazione strumentale) quali un pantografo, un software di geometria dinamica e una lavagna interattiva multimediale (LIM), per guidare studenti di seconda media all’idea di simmetria assiale come corrispondenza biunivoca tra punti del piano. Si è fatto riferimento alla teoria della mediazione semiotica (Bartolini Bussi e Mariotti, 2009) e alla struttura didattica in essa proposta: attività con artefatto a piccolo gruppo, attività individuale e discussioni collettive. Inoltre ci si è riferiti all’approccio strumentale (Rabardel, 1995) basato sulla distinzione fra artefatto e strumento. La LIM è stata utilizzata come spazio d’azione (Didoni, di Palma, 2009) per condividere azioni rese visibili alla classe. L’attività col pantografo è stata un’esperienza reale alla quale far riferimento nello svolgimento della sperimentazione. Gli esercizi con la LIM, utilizzata come touch-screen, hanno messo alla prova le congetture degli studenti creando situazioni nuove e inaspettate (conflitti cognitivi): lo strumento Traccia, tipico del software, è stato fondamentale per mediare significati e richiamare le modalità utilizzate (schemi d’utilizzo) nella prima fase col pantografo. Gli alunni hanno scoperto che i punti possono attraversare l’asse e che non c’è un semipiano privilegiato passando così da un’idea di simmetria come trasformazione di figure al concetto di corrispondenza biunivoca fra punti del piano.

Can massive Be/Oe stars be progenitors of long gamma ray bursts?

description: Context: The identification of long-gamma-ray-bursts (LGRBs) is still uncertain, although the collapsar engine of fast-rotating massive stars is gaining a strong consensus. Aims: We propose that low-metallicity Be and Oe stars, which are massive fast rotators, as potential LGRBs progenitors. Methods: We checked this hypothesis by 1) testing the global specific angular momentum of Oe/Be stars in the ZAMS with the SMC metallicity, 2) comparing the ZAMS ($Ω/Ω_{\rm c},M/M_{\odot}$) parameters of these stars with the area predicted theoretically for progenitors with metallicity $Z=0.002$, and 3) calculating the expected rate of LGRBs/year/galaxy and comparing them with the observed ones. To this end, we determined the ZAMS linear and angular rotational velocities for SMC Be and Oe stars using the observed vsini parameters, corrected from the underestimation induced by the gravitational darkening effect. Results: The angular velocities of SMC Oe/Be stars are on average $=0.95$ in the ZAMS. These velocities are in the area theoretically predicted for the LGRBs progenitors. We estimated the yearly rate per galaxy of LGRBs and the number of LGRBs produced in the local Universe up to z=0.2. We have considered that the mass range of LGRB progenitors corresponds to stars hotter than spectral types B0-B1 and used individual beaming angles from 5 to 15\degr. We thus obtain $R^{\rm pred}_{\rm LGRB}\sim10^{-7}$ to $\sim10^{-6}$ LGRBs/year/galaxy, which represents on average 2 to 14 LGRB predicted events in the local Universe during the past 11 years. The predicted rates could widely surpass the observed ones [(0.2-3)$\times10^{-7}$ LGRBs/year/galaxy; 8 LGRBs observed in the local Universe during the last 11 years] if the stellar counts were made from the spectral type B1-B2, in accordance with the expected apparent spectral types of the appropriate massive fast rotators. Conclusion: We conclude that the massive Be/Oe stars with SMC metallicity could be LGRBs progenitors. Nevertheless, other SMC O/B stars without emission lines, which have high enough specific angular momentum, can enhance the predicted $R_{\rm LGRB}$ rate.

description: The Heterodyne Instrument for the Far Infrared (HIFI) onboard the Herschel Space Observatory allows the first observations of light diatomic molecules at high spectral resolution and in multiple transitions. Here, we report deep integrations using HIFI in different lines of hydrides towards the high-mass star forming region AFGL 2591. Detected are CH, CH+, NH, OH+, H2O+, while NH+ and SH+ have not been detected. All molecules except for CH and CH+ are seen in absorption with low excitation temperatures and at velocities different from the systemic velocity of the protostellar envelope. Surprisingly, the CH(JF,P = 3/2_2,- - 1/2_1,+) and CH+(J = 1 - 0, J = 2 - 1) lines are detected in emission at the systemic velocity. We can assign the absorption features to a foreground cloud and an outflow lobe, while the CH and CH+ emission stems from the envelope. The observed abundance and excitation of CH and CH+ can be explained in the scenario of FUV irradiated outflow walls, where a cavity etched out by the outflow allows protostellar FUV photons to irradiate and heat the envelope at larger distances driving the chemical reactions that produce these molecules.

Suoni di rabbia e rime di pioggia: come riflettere sulla lingua attraverso la poesia
Creators: name: Manzocchi, Nora
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2016

description: La ricerca si propone di indagare la pertinenza di un laboratorio poetico in ottica di riflessione sulla lingua. Le radici di questo lavoro si legano allo studio svolto dalla scrittrice Chiara Carminati, nel suo libro Perlaparola. Il percorso didattico si basa sul metodo induttivo, che lascia quindi spazio alle interpretazioni personali e alle scoperte nate direttamente dal confronto e il dialogo tra gli allievi. Il focus verte su due aspetti secondo me principali della riflessione sulla lingua: il suono e la morfologia delle parole. L’indagine porta quindi i bambini a scoprire come è fatta una parola, da cosa è costituita sotto tutti i punti di vista, anche quello sonoro. Si tratta di interrogare la lingua e, in particolar modo, il testo poetico, utilizzando la lingua stessa, giocando con essa, scegliendo e ordinando le parole seguendo un senso e le proprie emozioni. Attraverso le letture e le produzioni scritte personali, gli allievi si confrontano con il continuo dialogo tra significante e significato. Le analisi delle produzioni degli allievi e dei protocolli di discussioni mostrano il raggiungimento dell’obiettivo ultimo del laboratorio poetico: sviluppare una maggiore consapevolezza sull’uso della lingua lavorando sulla poesia, svolgendo poi una riflessione più generale che si adatti al linguaggio di tutti i giorni, sia orale che scritto.

Improving food security in Penticton, BC, through social networking and community capacity-building using participatory and action research
Creators: name: Benson, Donna
Publisher: name: University of British Columbia
Year: 2021

description: Food security agreements have been in force in Canada since 1976. Yet, between 2008 and 2015, Food Banks Canada identified a 26% increase in food bank use. Between 2008 and 2018, researchers stated only 20-25% of food insecure individuals utilized food banks. In November 2020, others identified 60,000 charities in Canada helping to feed those in need. Sustainable food security solutions seemed imperative. Food bank charities were not an adequate solution due to inconsistent quality and quantities of donated surplus. The current study, within the United Nations context of human rights, intended to improve awareness and access to healthy food in Penticton, BC, through participatory action research in collaboration with the Salvation Army food bank. Theoretical foundations underpinning the study included pragmatism, advocacy, participation, adaptive leadership, and empowerment theory. The study was grounded in assets-based community development, organizational and community engagement through social network expansion and capacity-building. The researcher was viewed as a critical friend with relevant skills. Eleven participants engaged during the three-cycle project. Cycle 1-2 included a six-person participatory team. In Cycle 1, preliminary interviews of 15-45 minutes with each team member explored study concepts. Seven focus groups discussed potential projects for implementation and community sectors where contacts with decision-making authority were accessible. Cycle 2 engaged sector representatives (education, media, governance, and agriculture) in five focus groups and six interviews. Assets, funding procedures, and collaborative capacity were assessed. Although Salvation Army sponsorship was lost due to changes in personnel and priorities, we defined functional barriers, partners, and strategies for community capacity-building. During the COVID-19 pandemic, the Cycle 3 intervention (CoVic Garden Box Project) included four paid university students and a project coordinator. Two facilities and 26 families grew food for themselves and the food bank. We installed 61 raised beds and generated 1580 pounds of produce. The Penticton city councillors unanimously approved further engagement with staff toward inclusion in the 2021 Municipal Plan. In October 2020, the Action Research Network of the Americas Executive Committee assigned a Sustainability Action Research Committee (ARC) to help move the work forward. A closing survey provided insights for future work.

description: The study aimed to reveal the effect of practicing modified motor activities on the self-confidence of physically disabled people. We chose the sample in a purposive manner consisting of (12) motor disabled people who practice adapted physical activities and (12) motor disabled people who do not practice them. A self- onfidence scale prepared by By the researchers after arbitration. We found that people with physical disabilities who do not practice modified motor activities have a low level of self- confidence, while among those who practice it, the level of self-confidence is high. We also found statistically significant differences in the level ofself-confidence between practitioners and non- practitioners in favor of the category of practitioners.

title: Refashioning the caliphate : imperial vicissitudes and the deformation of order
Creators: name: Al-Dajani, Mahdi
Publisher: name: University of St Andrews
Year: 2016

description: Relying on the work of the political philosopher, Eric Voegelin, I argue that in the caliphate-related theoretical fabrics that appeared as of the Umayyad founding caliphs up to Al-Banna, a relation emerged between imperial vicissitudes, the ensuing anxieties and the desire to eliminate recalcitrant realities on one end, and the deformation of the meaning of the caliphate, of grand conceptions of order and of the mystery on the other end. Phases of Caliphal imperial ascent and imperial floating saw a mode of deformation which consisted of mystery-distorting conceptions, hence pointing to a metastatic consciousness which escaped from the metaxy heading towards the transcendent pole. Phases of imperial decay saw a mode of deformation which was characterized by a general avoidance of the mystery, and an immersion in profaneness, hence pointing to a metastatic consciousness which escaped form the metaxy heading towards the immanent pole. Both modes were outcomes of a superbia-based emotional difficulty preventing the libidinous self from bearing the persisting cognitive anxieties aroused by imperial vicissitudes. I demonstrate that characteristic of the phase of imperial ascent and imperial floating is the accentuation of the individual caliph/imam, and the customization of mystery distorting conceptions to solidify his status in the system of transcendental representation such as constructing him as God's deputy. This accentuation of the caliph is underpinned by the desire to boost his role in the system of existential representation especially his imperial status. Characteristic of the phase of imperial descent and imperial encroachment is the accentuation of the umma and the construction of the caliph as the umma's deputy, and a general avoidance of the mystery. The accentuation of the umma is underpinned by the desire to reinvent the system of existential representation and invoke maximal power which would end the state of imperial decay or encroachment.

description: The Fermi observatory is advancing our knowledge of Gamma-Ray Bursts (GRBs) through pioneering observations at high energies, covering more than 7 decades in energy with the two on-board detectors, the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM). Here we report on the observation of the long GRB 090217A which triggered the GBM and has been detected by the LAT with a significance greater than 9 sigma. We present the GBM and LAT observations and on-ground analyses, including the time-resolved spectra and the study of the temporal profile from 8 keV up to 1 GeV. All spectra are well reproduced by a Band model. We compare these observations to the first two LAT-detected, long bursts GRB 080825C and GRB 080916C. These bursts were found to have time-dependent spectra and exhibited a delayed onset of the high-energy emission, which are not observed in the case of GRB 090217A. We discuss some theoretical implications for the high-energy emission of GRBs.

Looking for the killer : a history of orca encounters, 1861-1964
Creators: name: Werner, Mark
Publisher: name: University of British Columbia
Year: 2023

description: This dissertation examines the emergence of the killer whale in popular and scientific discourses (1861-1964). Today, the orca is beloved, a potent symbol of nature and a marker of the tenuous future of our oceans in an age of climate catastrophe and ecological precarity. However, for much of western history, the orca has been a pariah, vilified for their predations and cast as a monstrous glutton. The dissertation seeks to understand the historical roots of the orca’s terrible reputation through an analysis of public discourses, fictional works, and scientific texts. This study traces discrete pieces of knowledge related to the orca’s character, seeking to understand how embodied experiences of both orcas and humans shaped the representations of the species over time. The dissertation features a set of case studies: a dissection of an orca in Denmark (1861), Antarctic encounters with orca in the early twentieth century (1910-1929), and a wayward orca who took up residence in a slough near Portland, Oregon (1931). The project employs a large-scale gathering of news coverage related to the orca, showcasing the possibilities of animal-centered history in the age of mass digitization. The dynamics of orca-human encounters are a crucial thread for this project. Special attention is paid to the embodied dynamics of these encounters, integrating historical sources with our present-day understanding of orca behaviors and cultures. The dissertation traces how first-hand encounters with orca were packaged – as scientific facts or wild animal stories – and, ultimately, how accounts of human-orca interactions were either incorporated into the orca’s folk-biological reputation or lost to the past. The dissertation considers how specific stories became canonical to understanding the species. The interplays – between belief and encounter, expectation and interaction, intimate first-hand encounter and second-hand recounting of the events – are reoccurring themes of the dissertation, speaking to the uneven record of human interactions with the killer whale and the historical contingency of human attitudes towards orca.

description: We investigate observational constraints on the generalized Chaplygin gas (GCG) model as the unification of dark matter and dark energy from the latest observational data: the Union SNe Ia data, the observational Hubble data, the SDSS baryon acoustic peak and the five-year WMAP shift parameter. It is obtained that the best fit values of the GCG model parameters with their confidence level are $A_{s}=0.73^{+0.06}_{-0.06}$ ($1σ$) $^{+0.09}_{-0.09}$ $(2σ)$, $α=-0.09^{+0.15}_{-0.12}$ ($1σ$) $^{+0.26}_{-0.19}$ $(2σ)$. Furthermore in this model, we can see that the evolution of equation of state (EOS) for dark energy is similar to quiessence, and its current best-fit value is $w_{0de}=-0.96$ with the $1σ$ confidence level $-0.91\geq w_{0de}\geq-1.00$.

Using interviews, archival material, ethnographic observations, and the analysis of public meetings on city preservation in Ouro Preto in 2013, I study how the city’s legacy as a national treasure of monumental architecture has endured until now, despite different coexisting standards of living, perceptions and uses of the city, and views of the past. In Ouro Preto, while fluctuating populations of tourists and students live mainly in the historic city centre, permanent residents often build their homes in underprivileged and marginalised areas and benefit little from their cultural heritage. Spatial exclusion and preservation policies, allegedly favouring outsiders, boost the divide between residents and newcomers, echoing the colonial past of the city. Disputes around the preservation of the cityscape invited widespread participation. One expectation of increased grassroots participation in cultural heritage sites is that it could expose varied and fluid perspectives of the city, and consequently allow for corresponding, more inclusive uses. However, when looking at local participatory practices in heritage policies, I consider the challenge for grassroots meetings to include different citizens and viewpoints, when the ability to disagree in public debates and participation are restricted by socio-economic conditions. The ethnographic character of this research offers a platform to investigate anthropological questions regarding the role, limits and expectations around cultural heritage and participatory practices in a context of varied socio-economic levels and fluid perceptions of aesthetics, history, and everyday uses of public spaces in a fragmented city.

description: XML has emerged as the standard for representing and exchanging data on the World Wide Web. It is critical to have efficient mechanisms to store and query XML data to exploit the full power of this new technology. Several researchers have proposed to use relational databases to store and query XML data. While several algorithms of schema mapping and query mapping have been proposed, the problem of mapping XML data to relational data, i.e., mapping an XML INSERT statement to a sequence of SQL INSERT statements, has not been addressed thoroughly in the literature. In this paper, we propose an efficient linear algorithm for mapping XML data to relational data. This algorithm is based on our previous proposed inlining algorithm for mapping DTDs to relational schemas and can be easily adapted to other inlining algorithms.

description: We investigate the old star clusters in the sample of cluster candidates from Froebrich, Scholz & Raftery 2007 -- the FSR list. Based on photometry from the 2-Micron All Sky Survey we generated decontaminated colour-magnitude and colour-colour diagrams to select a sample of 269 old stellar clusters. This sample contains 63 known globular clusters, 174 known open clusters and 32 so far unclassified objects. Isochrone fitting has been used to homogeneously calculate the age, distance and reddening to all clusters. The mean age of the open clusters in our sample is 1Gyr. The positions of these clusters in the Galactic Plane show that 80% of open clusters older than 1Gyr have a Galactocentric distance of more than 7kpc. The scale height for the old open clusters above the Plane is 375pc, more than three times as large as the 115pc which we obtain for the younger open clusters in our sample. We find that the mean optical extinction towards the open clusters in the disk of the Galaxy is 0.70mag/kpc. The FSR sample has a strong selection bias towards objects with an apparent core radius of 30" to 50" and there is an unexplained paucity of old open clusters in the Galactic Longitude range of 120deg < l < 180deg.

description: Loss is a critical roadblock to achieving photonic quantum-enhanced technologies. We explore a modular platform for implementing integrated photonics experiments and consider the effects of loss at different stages of these experiments, including state preparation, manipulation and measurement. We frame our discussion mainly in the context of quantum sensing and focus particularly on the use of loss-tolerant Holland-Burnett states for optical phase estimation. In particular, we discuss spontaneous four-wave mixing in standard birefringent fibre as a source of pure, heralded single photons and present methods of optimising such sources. We also outline a route to programmable circuits which allow the control of photonic interactions even in the presence of fabrication imperfections and describe a ratiometric characterisation method for beam splitters which allows the characterisation of complex circuits without the need for full process tomography. Finally, we present a framework for performing state tomography on heralded states using lossy measurement devices. This is motivated by a calculation of the effects of fabrication imperfections on precision measurement using Holland-Burnett states.

description: Lenstra's integer factorization algorithm is asymptotically one of the fastest known algorithms, and is ideally suited for parallel computation. We suggest a way in which the algorithm can be speeded up by the addition of a second phase. Under some plausible assumptions, the speedup is of order log(p), where p is the factor which is found. In practice the speedup is significant. We mention some refinements which give greater speedup, an alternative way of implementing a second phase, and the connection with Pollard's "p-1" factorization algorithm.

The phase diagram of random Boolean networks with nested canalizing functions

description: We obtain the phase diagram of random Boolean networks with nested canalizing functions. Using the annealed approximation, we obtain the evolution of the number $b_t$ of nodes with value one, and the network sensitivity $λ$, and we compare with numerical simulations of quenched networks. We find that, contrary to what was reported by Kauffman et al. [Proc. Natl. Acad. Sci. 2004 101 49 17102-7], these networks have a rich phase diagram, were both the "chaotic" and frozen phases are present, as well as an oscillatory regime of the value of $b_t$. We argue that the presence of only the frozen phase in the work of Kauffman et al. was due simply to the specific parametrization used, and is not an inherent feature of this class of functions. However, these networks are significantly more stable than the variants where all possible Boolean functions are allowed.

description: Con questo progetto ed annesso lavoro di ricerca sarà osservata la qualità della collaborazione all’interno del gruppo classe durante le unità didattiche dedicate alla robotica educativa, più precisamente attraverso l’uso del robot Thymio. È mio interesse valutare se ed in che misura l’introduzione di uno strumento innovativo nella progettazione annuale possa favorire la collaborazione all’interno di un gruppo classe. Numerose ricerche hanno dimostrato come la robotica possa essere inserita nella didattica odierna e come gli allievi possano trarne benefici. Infatti, grazie a questi momenti, è possibile sviluppare numerose competenze trasversali e disciplinari ed è mio intento verificare in che misura possono apportare cambiamenti. Il progetto fa ricorso al metodo qualitativo con intervento, propongo quindi un itinerario con approccio scientifico che vede come protagonista il robot Thymio. Gli allievi hanno lavorato in gruppi da 3-4 scelti sulla base di criteri precisi provenienti da un’osservazione attenta delle relazioni e dei bisogni del singolo e del gruppo intero. Tale ricerca ha rilevato che l’itinerario didattico ha portato numerosi benefici per le relazioni tra gli allievi, è stata favorito anche l’emergere di nuove identità competenti e l’integrazione di un nuovo allievo.
