description: Vi siete mai chiesti cosa pensano i bambini riguardo alla valutazione? Se un allievo è chiamato a valutare un testo di un compagno o il proprio come si comporta? Cosa valuta? Questa Tesi di Bachelor ha cercato di rispondere a questi quesiti mettendo i bambini di una pluriclasse di terza, quarta e quinta elementare, nella condizione di valutare testi propri e dei compagni. Nel presente lavoro, impiegando la valutazione tra pari e l’autovalutazione, si desiderava sperimentare la valutazione per l’apprendimento – valutazione formativa introdotta e definita nel nuovo Piano di studio – che invita i docenti a coinvolgere gli allievi in questo processo in modo da renderli maggiormente consapevoli riguardo ai propri apprendimenti. Lo scopo del progetto era verificare se le esperienze di valutazione tra pari, sperimentate dai bambini, potessero migliorare la loro capacità autovalutativa e modificare la loro rappresentazione del concetto di valutazione. Tramite un confronto fra pre-test e post-test, la ricerca ha permesso di evidenziare che i momenti proposti di valutazione tra pari e le riflessioni a grande gruppo, hanno trasformato la concezione di valutazione degli alunni, arricchendola del significato formativo. Inoltre la sperimentazione ha portato dei benefici nell’autovalutazione: gli aspetti considerati dagli allievi nel post-test sono aumentati sia in quantità sia con l’aggiunta di nuovi elementi e ad essi si sono affiancati consigli utili a migliorare.

description: We investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk has dissipated. In the model, the perturbations from Jupiter and Saturn are considered. We also consider variations of the mass of outer planet, and the initial eccentricities and inclinations of embryos and planetesimals. Our results show that, terrestrial planets are formed in 50 Myr, and the accretion rate is about 60% - 80%. In each simulation, 3 - 4 terrestrial planets are formed inside "Jupiter" with masses of $0.15 - 3.6 M_{\oplus}$. In the 0.5 - 4AU, when the eccentricities of planetesimals are excited, planetesimals are able to accrete material from wide radial direction. The plenty of water material of the terrestrial planet in the Habitable Zone may be transferred from the farther places by this mechanism. Accretion may also happen a few times between two giant planets only if the outer planet has a moderate mass and the small terrestrial planet could survive at some resonances over time scale of $10^8$ yr.

Pharmacokinetic and pharmacodynamic properties of cationic liposomal delivery of the immunomodulatory agent R848 to the mouse peritoneal cavity for the treatment of advanced peritoneal cancer
Creators: name: Pauli, Griffin William
Publisher: name: University of British Columbia
Year: 2021

description: Peritoneal cancer, defined as malignancies on the lining of the abdominal viscera, often originates from metastatic lesions in the ovaries, stomach and colon. The diffuse spreading of this cancer in the abdominal cavity makes it difficult to treat and causes relatively high recurrence rates. Currently, peritoneal cancer is treated by cytoreductive surgery and locoregional chemotherapeutic regimes. This procedure is associated with high morbidity and mortality, while not being sufficiently effective in diminishing recurrence rates. We hypothesized that peritoneal cancer treatment could benefit from an immunotherapeutic approach to reduce recurrence via generation of an anti-tumour immune response and modulation of the tumour microenvironment. To address this, we developed a liposome-based delivery system for the immune boosting agent Resiquimod (R848). We found that the liposomes incorporated with a positively charged lipid 1,2-stearoyl-3-trimethylammonium-propane (DSTAP) delivered by intraperitoneal (IP) injection increased peritoneal retention of R848 while minimizing its systemic absorption. Specifically, we observed that the peritoneal area under the curve concentration of R848 was 14 times greater when in the DSTAP-liposomes relative to the free drug formulation. Within 1 h post IP injection, ~60% of monocytes and macrophages, ~10% dendritic cells and ~8% natural killer (NK) cells in the peritoneal fluid were found to contain the liposomes. DSTAP-R848 significantly upregulated the production of TNF-α (2-fold), IL-6 (4-fold) and IFN-α (10-fold) mRNA relative to PBS control, leading to significantly reduced tumour progression in an IP metastasis model of CT-26 colorectal cancer in mice. Free R848 was ineffective in inducing the immune promoting cytokines nor antitumour efficacy. We demonstrated that DSTAP-R848 increased the trafficking of innate immune cells, specifically NK cells, in the peritoneal cavity.

description: We present the poster titled 'Probing into emission mechanisms of \thisgrb using time-resolved spectra and polarization studies: Synchrotron Origin? In this work, we have explored different aspects of the prompt emission and afterglow of multi-pulsed GRB 190530A (the sixth most fluent GBM burst detected so far) detected by the GBM and LAT and compared them with similar bursts. This poster presents the timing, spectral, and polarimetric analysis of the prompt emission observed using AstroSat and Fermi to provide insight into the prompt emission radiation mechanisms. Furthermore, we also report the earliest optical observations constraining afterglow polarization using the MASTER and the redshift measurement (z= 0.9386) obtained with the 10.4m GTC telescopes, making the burst the first case where both prompt emission and afterglow polarization measurements are constrained.

description: A graph is a structure composed of a set of vertices (i.e.nodes, dots) connected to one another by a set of edges (i.e.links, lines). The concept of a graph has been around since the late 19$^\text{th}$ century, however, only in recent decades has there been a strong resurgence in both theoretical and applied graph research in mathematics, physics, and computer science. In applied computing, since the late 1960s, the interlinked table structure of the relational database has been the predominant information storage and retrieval model. With the growth of graph/network-based data and the need to efficiently process such data, new data management systems have been developed. In contrast to the index-intensive, set-theoretic operations of relational databases, graph databases make use of index-free, local traversals. This article discusses the graph traversal pattern and its use in computing.

description: Purpose. The purpose of the article is to outline trends and priorities for the study of responsible investment in the context of sustainable development and explore research institutions and publishing activities in this area. Methodology / approach. The study used bibliometric, structural, cluster and graphic analysis, as well as methods for visualizing the publishing activity of scientists on responsible investment according to the Web of Science platform and using VOSviewer software. Results. Based on a study of 1534 articles on the topic of responsible investment, in such areas of analysis as publication categories, dynamics of publications, types of organizations, authors' activity, publishing rating, countries of publication activity, citations of articles, clustering of terms and cited authors, the bibliometric field of this concept was characterized and visualized. The most cited articles which are directed on revealing of tendencies of disclosure and the subsequent monitoring of subjects of VI as bases of sustainable development of economy are investigated. The publishing activity of the authors and the most cited and relevant articles are analyzed. Four thematic clusters in the study of responsible investment (empirical, behavioral, generalizing and supporting) and the most famous institutions, involved in the study of responsible investment, were revealed. Originality / scientific novelty. The main parameters of the bibliometric field of responsible investment were characterized by means of cluster, structural and graphical analysis of the dynamics of individual indicators. For the first time, on the basis of the identified clusters, the affiliation of the research topic to the related “empirical” and “supply” cluster was determined. It was determined that the connection between clusters of responsible investment is manifested in their role as tools and at the same time strategies for the formation of new investment opportunities. Practical value / implications. The obtained results allow substantiating the key approaches to understanding responsible investment and the most priority areas of its research, to determine the sources of its scientific and methodological support on the way to sustainable development.

description: We investigate the possibility of correcting errors occurring on a multipartite system through a feedback mechanism that acquires information from partial access to the environment. A partial control scheme of this kind might be useful when dealing with correlated errors. In fact, in such a case, it could be enough to gather local information to decide what kind of global recovery to perform. Then, we apply this scheme to the depolarizing and correlated errors, and quantify its performance by means of the entanglement fidelity.

description: We present the correlations between the spectroscopic metallicities and ninety-three different intrinsic colors of M31 globular clusters, including seventy-eight BATC colors and fifteen SDSS and near infrared ugrizK colors. The BATC colors were derived from the archival images of thirteen filters (from c to p), which were taken by Beijing-Arizona-Taiwan-Connecticut (BATC) Multicolor Sky Survey with a 60/90 cm f/3 Schmidt telescope. The spectroscopic metallicities adopted in our work were from literature. We fitted the correlations of seventy-eight different BATC colors and the metallicities for 123 old confirmed globular clusters, and the result implies that correlation coefficients of twenty-three colors r>0.7. Especially, for the colors $(f-k)_0$, $(f-o)_0$, and $(h-k)_0$, the correlation coefficients are r>0.8. Meanwhile, we also note that the correlation coefficients (r) approach zero for $(g-h)_0$, $(k-m)_0$, $(k-n)_0$, and $(m-n)_0$, which are likely to be independent of metallicity. Similarity, we fitted the correlations of metallicity and ugrizK colors for 127 old confirmed GCs. The result indicates that all these colors are metal-sensitive (r>0.7), of which $(u-K)_0$ is the most metal-sensitive color. Our work provides an easy way to simply estimate the metallicity from colors.

description: Chern insulators are band insulators exhibiting a nonzero Hall conductance but preserving the lattice translational symmetry. We conclusively show that a partially filled Chern insulator at 1/3 filling exhibits a fractional quantum Hall effect and rule out charge-density wave states that have not been ruled out by previous studies. By diagonalizing the Hubbard interaction in the flat-band limit of these insulators, we show the following: The system is incompressible and has a 3-fold degenerate ground state whose momenta can be computed by postulating an generalized Pauli principle with no more than 1 particle in 3 consecutive orbitals. The ground state density is constant, and equal to 1/3 in momentum space. Excitations of the system are fractional statistics particles whose total counting matches that of quasiholes in the Laughlin state based on the same generalized Pauli principle. The entanglement spectrum of the state has a clear entanglement gap which seems to remain finite in the thermodynamic limit. The levels below the gap exhibit counting identical to that of Laughlin 1/3 quasiholes. Both the 3 ground states and excited states exhibit spectral flow upon flux insertion. All the properties above disappear in the trivial state of the insulator - both the many-body energy gap and the entanglement gap close at the phase transition when the single-particle Hamiltonian goes from topologically nontrivial to topologically trivial. These facts clearly show that fractional many-body states are possible in topological insulators.

description: Dopo un breve quadro teorico relativo alla storia della Scuola media ticinese, alla storia della grammatica italiana e del suo insegnamento nel secondo dopoguerra e alla storia dei programmi scolastici, il presente lavoro si propone di documentare e analizzare i cambiamenti relativi alla grammatica italiana all’interno dei programmi della Scuola media ticinese. Il confronto fra le indicazioni dei programmi delle varie Scuole medie precedenti l’introduzione della Scuola media unica (Ginnasio, Scuola maggiore, Scuola di avviamento professionale e commerciale, Scuola di economia domestica) e le indicazioni contenute nei programmi della Scuola media unica mette in rilievo i profondi cambiamenti strutturali, pedagogici e didattici che coinvolsero l’ultima fase della scuola obbligatoria fin dalla seconda metà degli anni Settanta, a partire dalle informazioni sulla grammatica italiana: dalle stringate indicazioni contenutistiche e metodologiche dei programmi precedenti l’introduzione della Scuola media unica, si è passati a veri e propri trattati organici, con prescrizioni molto precise, che lasciano trasparire l’influsso delle recenti scoperte linguistiche (Dieci tesi del GISCEL, sociolinguistica, grammatica valenziale e trasformazionale, etc.), senza rinunciare alle classificazioni tradizionali relative a quest’ambito dell’italiano, a testimonianza di un dibattito internazionale tuttora irrisolto sull’argomento.

description: The multiphase flow reactors are extensively used in chemical and biochemical industries. Where perfect mixing and ideal mass and heat transfer are importance. In this work, pilot plant scale of bubble column reactor was used for air-water system. The local hydrodynamics can considerably affect the reactor conduct. Due to the local hydrodynamics parameters are the main factor for multiphase reactor design. Consequently, effective reactor design and successful scale-up require a suitable understanding of the local hydrodynamics for multiphase flow through the reactor running stages. Unfortunately, these parameters need to be further developed and evaluated to account of 3D flow field in each position inside the reactor in industry scale (pilot plant) which is unclear yet and need more information for deeply understanding. Therefore, In our laboratory (Multiphase Reactors and Applications Laboratory MReal), an advanced diagnostic techniques for industrial scale have been well established and used extensively for monitoring the flow field in a non-invasive manner in opaque multiphase pilot plant reactor systems in column diameter 18-inch (0.46 m) Plexiglas reactor with height 144 inches (3.66m). A non-invasive advanced measurement technique called Radioactive particle tracking (RPT) (see Figure 1) for large scale columns has been implemented to provide detailed and in 3D hydrodynamic parameters (velocity components, turbulent parameters, shear stresses, normal stresses, kinetic energy, and eddy diffusivity). For present study, quantifies of the flow characterization in the time series of lagrangian tracer particle trajectory are available for fluctuating liquid velocity fields at various superficial gas velocities (10 and 45 cm/sec). As a conclusion, the experimental results provide benchmark data for simulation, design, scale-up, and performance of the pilot plant scale bubble column reactors. The experimental results and conclusions will present at the conference.
The vanishing point : a black feminist paradigm on the early modern canon in the national galleries
Creators: name: Casini, Ilaria
Publisher: name: University of British Columbia
Year: 2021

description: The Vanishing Point series of drawings by contemporary British artist Barbara Walker consists of replicas of early modern paintings in which a Black figure is depicted in a service, subordinate role within the composition, creating clear and harmful power dynamics with the white main subjects. With the help of technology Walker removes the overall scene leaving it almost abstracted through the technique of embossing and draws out the Black figure in graphite. By transferring visibility back to the Black subject, and offering another perspective or interpretation on the works, to contrast with the institutional position, Walker emphasises the absence of Black representation in the national archives and, by extension, in the collective memory of British society. This thesis considers Walker’s series potential as paradigm of anti-racist, Black feminist approach/action in order to challenge and disrupt the very conception of National Galleries’ Western canonical art historical discourse. By analysing Walker’s work, I do not contend it to be purely her — or any other minority artist’s— responsibility to challenge the canonical discourse. On the contrary, employing Giorgio Agamben’s theories on profanation, I argue for the public national institutions’ urgent active engagement in an act of self-profanation, explicitly exposing the construction of their self professed authority and of the Western art historical narrative. The main narration of my thesis considers the implications of Walker’s drawings as critical replicas of past epistemologies establishing a dialogue with early modern ideologies and reflecting on their repercussions on the social fabric of the present. A parallel discussion, taking place through interludes between the main chapters, speculates over the future of institutional handling of historical art, and the changing positions towards museum-going among the public. The research aims at expressing the necessity of new readings of canonical texts and works, in order to make whiteness and its power visible, while simultaneously acknowledging the interpretative powers and agencies of minorities in defining and expressing their experiences as subjects.

description: This study focuses on identity formation as it relates to teachers and the heterosexist microaggressions that can be experienced. Using critical autoethnography, I reflect on, write, and analyze narratives written based upon both my own and my colleagues’ experiences. Critical qualitative research on the experiences of queer individuals in education has grown in the past decade, however, more first-hand experiences need to be shared to expose the need for all individuals to examine their behavior and beliefs and how they may be attributing to microaggressions. Through my personal voice as a research participant (teacher) and analytical voice as a researcher, this thesis purposely incites chaos, disruption, and entangles perspectives and biases that are usually kept separate. Heterosexist microaggressions enliven the belief that heterosexuality is the norm and benchmark for society, othering those who fall outside of this measurement and shape their identity through different means. When this belief is unchallenged it threatens authenticity and inclusion for the genuine identity development of individuals to occur. As a result of this critical autoethnography, considerations for future research are offered in the hopes of encouraging those living unspoken narratives to make themselves visible and heard in an educational context to promote future fluidity and transformation.

description: We consider the non-deterministic extension of the call-by-value lambda calculus, which corresponds to the additive fragment of the linear-algebraic lambda-calculus. We define a fine-grained type system, capturing the right linearity present in such formalisms. After proving the subject reduction and the strong normalisation properties, we propose a translation of this calculus into the System F with pairs, which corresponds to a non linear fragment of linear logic. The translation provides a deeper understanding of the linearity in our setting.

On dust grains, H2 O is an important constituent of the icy mantle in which a complex chemistry is taking place, as revealed by hot core observations. The formation of water can occur on dust grain surfaces, and can impact gas phase composition. Aims. The formation of molecules such as OH, H2 O, HO2, H2 O2, as well as their deuterated forms and O2 and O3 is studied in order to assess how the chemistry varies in different astrophysical environments, and how the gas phase is affected by grain surface chemistry. Methods. We use Monte Carlo simulations to follow the formation of molecules on bare grains as well as the fraction of molecules released into the gas phase. We consider a surface reaction network, based on gas phase reactions, as well as UV photo-dissociation of the chemical species. Results. We show that grain surface chemistry has a strong impact on gas phase chemistry, and that this chemistry is very different for different dust grain temperatures. Low temperatures favor hydrogenation, while higher temperatures favor oxygenation. Also, UV photons dissociate the molecules on the surface, that can reform subsequently. The formation-destruction cycle increases the amount of species released into the gas phase. We also determine the time scales to form ices in diffuse and dense clouds, and show that ices are formed only in shielded environments, as supported by observations.

title: Farmers and herders in Ghana: examining the impact of livelihood and autochthony on the land conflict between indigenes and migrants
Creators: name: Boakye Gyan, Collins Kwaku Gyan
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: This study examines the underlying drivers of the conflict between Indigenous farmers and Fulani herders in two districts in Ghana: Asante Akim North and Gushegu districts. These two districts have witnessed the most violence in Ghana between 2001 and 2020. The research is anchored on land-use and land access theories, as well as autochthony and narratives of "Sons of the Soil". Based on data gathered from forty-five (45) media sources of local, national and international news articles in newspapers and online, including transcripts of extended interviews of leaders of both Indigenous farmers and Fulani herders done on national television and documents from the police, judicial service, traditional Council and Regional Security Council. This Study argues that the differences in the livelihood of the two groups of land users and the use of autochthony identity to deny Fulani herders access to land are the underlying drivers of the violent conflict between farmers and herders. Both farmers and herders need land for their livelihood; however, land access and use are contested and interpreted continuously within the spheres of identity. The focus on the farmer-herder conflict in Ghana emphasizes that theories that seek to identify and explain the causes of group conflict must go beyond simple linear explanations to include complex multi-dimensional explanations.

description: Il DIY (Do It Yourself) non è solo un hobby, il DIY rappresenta una riappropriazione dei processi produttivi volti alla consapevolezza della produzione. “Autoprogettazione?” di Enzo Mari cerca di coinvolgere il consumatore proponendogli le istruzioni per la costruzione fai da te di oggetti tra cui la celebre Sedia 1 disegnata nel 1974. Il progetto di tesi propone la visualizzazione di 243 modi diversi per assemblare una sedia partendo da tre sedie di base realizzate ad incastro e ciascuna composta da cinque pezzi. Le tre sedie di base sono state disassemblate e grazie al calcolo combinatorio tutte le possibilità di riassemblaggio sono state illustrate rispettando l’ordine matematico che ne deriva dal calcolo delle permutazioni con ripetizione. Il progetto dimostra le possibilità che la comunicazione visiva offre nell’agevolare e tradurre una formula matematica applicata all’industria design.

Conformal or Walking? Monte Carlo renormalization group studies of SU(3) gauge models with fundamental fermions

description: Strongly coupled gauge systems with many fermions are important in many phenomenological models. I use the 2-lattice matching Monte Carlo renormalization group method to study the fixed point structure and critical indexes of SU(3) gauge models with 8 and 12 flavors of fundamental fermions. With an improved renormalization group block transformation I am able to connect the perturbative and confining regimes of the N_f=8 flavor system, thus verifying its QCD-like nature. With N_f=12 flavors the data favor the existence of an infrared fixed point and conformal phase, though the results are also consistent with very slow walking. I measure the anomalous mass dimension in both systems at several gauge couplings and find that they are barely different from the free field value.

description: Questo studio esplora l’impatto della pandemia da COVID-19 sulla scuola come comunità educante, analizzando il periodo di lockdown e le dinamiche conseguenti. Attraverso interviste semi-strutturate, coinvolgendo studenti, genitori, docenti e dirigenti scolastici, si esaminano tracce lasciate dalla pandemia, cambiamenti nella percezione dei genitori verso l’istituzione scolastica, pratiche di emergenza integrate e l’effetto della memoria storica sul comportamento della comunità educante. Durante la pandemia, vi è stata un’adattabilità condivisa tra i docenti, seguita da una stabilizzazione post-pandemica. Alcune pratiche di emergenza, come le riunioni online, sono diventate parte della routine, mentre la memoria storica ha avuto un impatto limitato sul comportamento dei docenti. Sebbene la pandemia abbia portato a cambiamenti significativi, il ritorno alla normalità indica una resilienza del sistema scolastico, ma richiede una valutazione continua degli impatti a lungo termine e della gestione delle sfide emergenti.

The importance of traditional dance music in asserting the cultural identity of the Greeks from Dobrogea
Creators: name: Kozlovsky, Mirela
Publisher: name: figshare

Subjects: Musicology and ethnomusicology

description: Dobrogea, the oldest province in all Romanian lands , is a unique ethnocultural landscape, characterized by the original contributions of each ethnic community. The variety of cultural identities results, on the one hand, from the continuity of the Romanian local element and, on the other hand, from the existence of minority groups. In the context of territorial proximity, cultural exchanges took place that determined in time a process of acculturation, but also the formation of distinctive frames of manifestation of each ethnic group. The existence of this ethnocultural mosaic determined the creation of close ties between Romanians and the mother nations of these nationalities, an aspect that determines the enrichment of Romanian cultures as a whole. For the Greeks from Dobrogea, dance music is an important part of the traditional music repertoire. The dance connects the participants with the community to which they belong, as well as asserting a strong cultural identity in the Dobrogean allogeneic space.

description: We report on the magnetic and phononic excitation spectrum of Sr3Cr2O8 determined by THz and infrared (IR) spectroscopy, and electron spin resonance (ESR) measurements across the Jahn-Teller transition, which is detected by specific-heat measurements to occur at T_{JT} = 285 K. We identify the singlet-triplet excitations in the dimerized ground state and estimate the exchange couplings in the system. Moreover, ESR absorptions were observed up to T* = 120 K with a linewidth proportional to exp{-Delta/k_{B}T} and Delta/k_{B} = 388 K indicating a phonon-mediated spin relaxation via the excited orbital state of the Cr $e$ doublet in the orbitally ordered state. In contrast to the expected drastic change of the IR active phonons upon entering the low-symmetry Jahn-Teller distorted phase below T_{JT}, we find an extended regime T*

Identification of natural compounds to quench quorum sensing in Campylobacter jejuni for the reduction of biofilm formation
Creators: name: Li, Shenmiao
Publisher: name: University of British Columbia
Year: 2021

description: Quorum sensing is a process of bacterial intercellular communication that relies on the production and perception of chemical signals called autoinducers. Via quorum sensing, bacteria can modulate a range of behaviours in response to the change of population density for better fitness. Quorum sensing mediated biofilm formation is a vital survival strategy for many bacteria. At a high population density, bacteria can aggregate and attach to a surface by producing and secreting extracellular polymeric substances (EPS). The surrounding EPS protects the encased cells from the unfavourable conditions. Campylobacter jejuni is a major bacterial cause of human diarrhoeal diseases worldwide. Despite its sensitivity to environmental stresses, C. jejuni ubiquitously distributes throughout the poultry production chain. Autoinducer-2 (AI-2) mediated biofilm formation is known to be critical to the environmental survival of C. jejuni. C. jejuni possesses LuxS, the enzyme involved in the production of AI-2. In this dissertation, two natural fatty acids, namely decanoic acid and lauric acid, were identified as AI-2 inhibitors of C. jejuni. Decanoic acid and lauric acid at 100 ppm inhibited ~90% AI-2 activity of C. jejuni without inactivation of the bacterial cells. Anti-biofilm effect of decanoic acid and lauric acid was investigated. C. jejuni culture was incubated with or without the treatment by fatty acids for 72 h. Biofilm biomass was determined by crystal violet assay, and the numbers of viable planktonic and biofilm-associated cells were separately determined by the conventional plating assay. Except one C. jejuni strain increased biofilm biomass at the treatment groups, the fatty acids reduced 10-50% of the biofilm biomass in the other strains. Lauric acid at 100 ppm achieved ~3-log and ~2-log reduction of C. jejuni biofilm-associated and planktonic cells, respectively. In addition, both fatty acids effectively reduced C. jejuni motility. This study identified the AI-2 inhibitors of C. jejuni and investigated their inhibitory effect on biofilm formation and motility. The findings of this study can aid in the development of alternative C. jejuni control strategies.
