Active shooter events in K-12 schools have increased since 1990, and developing response policies to such events is a responsibility of school personnel. A paucity of data regarding options-based response practices existed with no focus on policy processes. The purpose of this qualitative multi-case study was to describe the decision-making processes used in school districts when approving the inclusion of options-based responses to active shooter events in Emergency Operations Plans (EOPs). The research questions addressed processes that shaped the development of options-based responses to active shooter policies in 3 K-12 school districts within the Midwest. The conceptual framework was informed by the theory of policy paradox and the concepts of situational awareness and resilience. Structured interviews were conducted with 12 school personnel and safety professionals involved in 3 high schools; EOPs and state and federal regulations and guidelines were reviewed. An analysis of the interview responses and document reviews using four levels of descriptive coding required a cross-case analytic technique to discover patterns, connections, and themes. Law enforcement and school personnel worked together to create policy and to implement trainings related to options-based response. Results included enhancing situational awareness and empowering teachers and students to become responsible for their safety. These findings can be used to inform and guide school leaders in their efforts to make policy and implementation decisions regarding active shooter policies in EOPs. The potential for social change exists in more school personnel understanding and implementing options-based response policies and making the lives of K-12 students safer.

In this thesis I consider the influence of Alice Brill's transnational background on her photographs of 1950s São Paulo. Brill was born in 1920 to a Jewish-German family. In 1934 she immigrated to São Paulo where she involved herself in local artistic circles. From 1946-47 she received a grant to study at the University of New Mexico and with the Art Students League in New York. Brill learned photography during her time in the United States, hoping to create documentary photo-essays in Brazil which she could send to American illustrated magazines. None of Brillss works were published in the United States, however, on returning to São Paulo in 1948 Brill was invited by Pietro Maria Bardi, Director of the Museu de Arte de São Paulo Assis Chateaubriand, to "record the daily life of the citizens of São Paulo". Bardi intended the photographs to be published as an homage to the city's 400th anniversary, but lacked sufficient funding to complete the volume. Brill's images of São Paulo depict the metropolis in a way unique during the period: as a space shared by multi-racial communities. While many photographers and publications metaphorically white-washed the city by depicting only its most Europeanized attributes, Brill consciously sought out underrepresented groups, specifically the burgeoning Afro-Brazilian community. Brill's point of view was shaped by her international upbringing and training: her experience as an outsider compelled her to document other outsider communities in São Paulo. She recognized the traditions of representation already in place in Brazil and manipulated familiar types in order to represent the nation's true hybridity. Influences on her work include: the long history of part-artistic, part-anthropological studies of the Brazilian people; local photographic traditions for picturing the city and its inhabitants; the European photojournalist style introduced to Brazil in 1944; and the international sensibility of Brill's patrons, the Bardis. I attempt to show how Brill balanced these considerations with her own personal understanding of Brazil as a multivalent space.

Transmedia är ett brett ämne. Den här textanalysen undersöker designen av nio olika versioner av Alice i Underlandet med hjälp av kvalitativ data, med fokus på hur transmedial karaktärsdesign utvecklats historiskt och över olika former av media, samt om det går att utröna vilka karaktärsdrag som ändras mest/minst mellan de olika adaptionerna. Varje version av Alice gås noggrant igenom och analyseras jämte med originaltexten samt de andra adaptionerna, och gemensamma egenskaper som nyfikenhet, envishet och impulsivitet identifieras. Den här textanalysen bidrar till att fylla en lucka i forskningen om att bättre förstå transmedial karaktärsdesign och dess utveckling. Framtida arbeten som kan var intressant att fortsätta med är att göra en mer socialt och samhälleligt komplex analys som har fokus på etnicitet, genus samt social/ekonomisk klass, något som den här analysen inte inkluderar. / <p>Det finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.</p>

Emma Löfvendahl och Lina Karlsson (2023) Underlandet - En adaptionsstudie av Lewis Carrolls originalversion och Disneys film. Självständigt arbete, Svenska, inriktning F-3, grundnivå, 15 högskolepoäng. Institutionen för humaniora, utbildnings- och samhällsvetenskap. Syftet med denna studie är att undersöka förändringar som gjorts vid adaptionen av Lewis Carrolls verk Alice i underlandet till Disneys filmversion. Det som mer specifikt fokuseras på vid analysen är de skillnader och likheter som finns mellan verkens karaktärsgestaltning och intrigens skildring. Vidare förs även en didaktisk diskussion kring hur dessa verk kan användas i grundskolans F-3. Uppsatsen är en komparativ adaptionsstudie som jämför verken med utgångspunkt ur Maria Nikolajevas begrepp kring barnlitteratur. Analysen visar att de viktiga karaktärsdragen skildras överensstämmande i adaptionen i jämförelse med originalverket. Intrigens kärna är bevarad i filmadaptionen och är därför sann till originalverket trots de förändringar som skett. Resultatet visar att de skillnader som skett i adaptionen är betingade av mediets påverkan och disneyfication.

Sophie Duty: Att använda bilderboken som en lättläst version av kapitelboken - en komparativ adaptionsanalys av en kapitelbok och bilderbok om Alice i Underlandet av Lewis Carroll (2022). Svenska, självständigt arbete avancerad nivå, 15 högskolepoäng. Örebro universitet, institutionen för humaniora, utbildnings- och samhällsvetenskap. Syftet med denna studie är att undersöka om det är det lämpligt att använd sig av bilderboken som en lättläst version av kapitelboken i undervisningen för åk f-3 och vilka möjligheter och utmaningar det i så fall finns. För att undersöka detta har en komparativ adaptions analys med både en kvalitativ och kvantitativ metod genomförts. Jag har jämfört kapitelboken Alice i underlandet (2016) med bilderboken Alice i Underlandet (2015) genom att titta på skillnader i deras intriger, handlingens komposition och hur de använder av bilder som stöd. Analysen visar att trots att det finns skillnader i verkens episoder så är intrigerna lika varandra. Den stora skillnaden som funnits är i hur handlingarnas komponerats och om användningen av bilder som stöd för texten skiljer sig i de olika böckerna? I så fall hur? Avslutningsvis har dessa resultat använts i en didaktisk diskussion kring bilderbokens lämplighet att användas som en lättläst version av kapitelboken i undervisningen för åk f-3 och vilka möjligheter och utmaningar finns det i så fall

Les collisions d’ions lourds ultrarelativistes ont pour objectif principal l'étude des propriétés de la matière nucléaire soumise à températures et densités d'énergie extrêmes. La chromodynamique quantique (QCD) prédit, dans ces conditions, l’existence d’une nouvelle phase de la matière dans laquelle les constituants des hadrons sont déconfinés en un plasma de quarks et gluons (QGP). Les saveurs lourdes (charme et beauté) sont produites lors de processus durs aux premiers instants des collisions, avant de traverser le milieu. Par conséquent, la mesure des quarkonia (mésons cc et bb) est particulièrement intéressante pour l'étude du QGP : leur dissociation, due notamment à l’écrantage de couleur, est sensible à la température initiale du système. Les mesures effectuées au SPS et RHIC ont permis de mettre en évidence plusieurs caractéristiques du milieu produit, mais ont aussi laissé plusieurs questions sans réponse. Avec une énergie 14 fois supérieure à celle du RHIC, l’accélérateur LHC (Large Hadron Collider) au CERN, entré en fonctionnement fin 2009, a ouvert une nouvelle ère pour l'étude des propriétés du QGP. ALICE (A Large Ion Collider Experiment) est une des quatre grandes expériences fonctionnant auprès du LHC et dont le but principal est l'étude du plasma de quarks et gluons produit dans les collisions d'ions plomb à une énergie de 2.76 TeV par nucléon. Elle enregistre aussi des collisions pp afin de fournir la référence indispensable pour l'étude des collisions noyau-noyau et proton-noyau et de tester les calculs perturbatifs de QCD dans la région des faibles valeurs de la variable d'échelle x de Bjorken. Les quarkonia, ainsi que les saveurs lourdes ouvertes et les mésons légers, sont mesurés dans ALICE suivant leur mode de désintégration muonique avec le spectromètre à muons situé à petit angle polaire. Il est constitué d'un ensemble d’absorbeurs, d’un dipôle chaud, de cinq stations de trajectographie (Muon Tracking) et de deux stations de déclenchement (Muon Trigger). Le travail présenté dans cette thèse a été réalisé de 2011 à 2013 pendant les premières années de prise de données dans l’expérience ALICE. Après une introduction à la physique des ions lourds à hautes énergies et une description du setup expérimental, une étude des performances du Muon Trigger en Pb-Pb est proposée. En particulier, la stabilité dans le temps du détecteur et son efficacité de fonctionnement sont contrôlées. Le cluster size, correspondant au nombre moyen de voies adjacentes touchées par particule détectée, est étudié en fonction des différents variables. Les valeurs expérimentales sont comparées à des simulations afin de fournir une paramétrisation de cet effet. Finalement, la production du méson Ç en collisions Pb-Pb est analysée en détail et comparée à celle en collisions pp à la même énergie. Les résultats obtenus sont comparés aux mesures du J/ψ par ALICE, aux mesures par CMS et à des prédictions de modèles théoriques. / The main goal of ultrarelativistic heavy-ion collisions is the study of the properties of the matter at very high temperatures and energy densities. Quantum chromodynamics (QCD) predicts in these conditions the existence of a new phase of the matter whose components are deconfined in a Quark-Gluon Plasma (QGP). Heavy quarks (charm e bottom) are produced in the first stages of the collisions, before to interact with the medium. Therefore, the measurement of the quarkonia (cc and bb mesons) is of particular interest for the study of the QGP: their dissociation mainly due to the colour screening is sensible to the initial temperature of the medium. Previous measurements at the SPS and RHIC allowed to understand some characteristics of the system produced, but they also opened many questions. With an energy 14 times higher than RHIC, the LHC (Large Hadron Collider) at CERN opened a new era for the study of the QGP properties. ALICE (A Large Ion Collider Experiment) is the LHC experiment fully dedicated to the study of the Quark-Gluon Plasma produced in Pb-Pb collisions at an energy of 2.76 TeV per nucleon. The experiment also participates to the proton-proton data taking in order to obtain the fundamental reference for the study of ion-ion and proton-ion collisions and for testing the predictions at very small Bjorken-x values of the perturbative QCD. Quarkonia, D and B mesons and light vector mesons are measured at forward rapidity by a Muon Spectrometer exploiting their (di)muonic decay. This detector is composed of a front absorber, a dipole magnet, five stations of tracking (Muon Tracking) and two stations of trigger (Muon Trigger). The work presented in this thesis has been carried out from 2011 to 2013 during the first period of data taking of ALICE. After a detailed introduction of the heavy-ion physics and a description of the experimental setup, the performance of the Muon Trigger in Pb–Pb collisions are shown. A particular attention is devoted to the stability of the detector during the time and to the trigger effectiveness. Moreover, the cluster size, corresponding to the number of adjacent strips hit by a particle, is studied as a function of different variables. The experimental results will be compared to simulations in order to obtain a good parametrization of this phenomenon. Finally, the Ç production in Pb-Pb collisions is carefully analysed and compared to that in pp collisions at the same energy. The results are then compared to the J/ψ measurements obtained by ALICE, to the CMS results and to some theoretical predictions.

Heavy-ion collisions are a powerful tool to study hot and dense QCD matter, the so-called Quark Gluon Plasma (QGP). Since heavy quarks (charm and beauty) are dominantly produced in the early stages of the collision, they experience the complete evolution of the system. Measurements of electrons from heavy-flavour hadron decay is one possible way to study the interaction of these particles with the QGP. With ALICE at LHC, electrons can be identified with high efficiency and purity. A strong suppression of heavy-flavour decay electrons has been observed at high $p_{m T}$ in Pb-Pb collisions at 2.76 TeV. Measurements in p-Pb collisions are crucial to understand cold nuclear matter effects on heavy-flavour production in heavy-ion collisions. The spectrum of electrons from the decays of hadrons containing charm and beauty was measured in p-Pb collisions at $\\sqrt = 5.02$ TeV. The heavy flavour decay electrons were measured by using the Time Projection Chamber (TPC) and the Electromagnetic Calorimeter (EMCal) detectors from ALICE in the transverse-momentum range $2 < p_ < 20$ GeV/c. The measurements were done in two different data set: minimum bias collisions and data using the EMCal trigger. The non-heavy flavour electron background was removed using an invariant mass method. The results are compatible with one ($R_ \\approx$ 1) and the cold nuclear matter effects in p-Pb collisions are small for the electrons from heavy-flavour hadron decays. / Colisões de íons pesados relativísticos é uma ferramenta poderosa para se estudar o plasma de quarks e glúons (QGP). Quarks pesados ({\\it charm} e {\\it beauty}) são produzidos nos estágios iniciais da colisão e participam da evolução completa do sistema. Medidas de elétrons provenientes de quarks pesados é uma das possíveis formas de se estudar a interação destas partículas com o QGP. Utilizando o detetor ALICE do LHC, elétrons podem ser identificados com alta eficiência e boa pureza. Uma forte supressão de elétrons provenientes de quarks pesados foi observada em alto $p_$ em colisões de Pb-Pb a 2.76 TeV. Medidas do mesmo observável em colisões p-Pb são cruciais para se entender os efeitos da matéria nuclear fria na produção de tais partículas. O espectro de elétrons provenientes de hádrons que contêm {\\it charm} ou {\\it beauty} foi medido em colisões p-Pb a $\\sqrt = 5.02$ TeV. Os elétrons foram identificados utilizando o {\\it Time Projection Chamber} (TPC) e o {\\it Electromagnetic Calorimeter} (EMCal) do detetor ALICE, no intervalo de momento transversal de $2 < p_ < 20$ GeV/c. As medidas foram realizadas utilizando dois diferentes conjunto de dados: colisões de mínima tendenciosidade ({\\it minimum bias (MB)}) e colisões tomadas utilizando o trigger do EMCal. Os elétrons de fundo foram removidos utilizando um método de massa invariante. Os resultados são compatíveis com a unidade ($R_ \\approx$ 1) e os efeitos da matéria nuclear fria são pequenos para elétrons provenientes de quarks pesados.
