Les magiciens trompent souvent l’esprit des spectateurs en manipulant certaines de leurs limites cognitives. Ainsi, la magie offre probablement un terrain original pour étudier certains processus cognitifs tels que la perception, l’attention, le raisonnement... Dans cette thèse, nous proposons plusieurs recherches qui tentent d’étudier scientifiquement les mécanismes psychologiques en jeu dans la prestidigitation. Dans une première partie, nous discutons de l’intérêt de cette « science de la magie » en passant en revue les principales recherches du siècle dernier à aujourd’hui, puis en discutant de plusieurs terrains d’investigations inexplorés et sans doute prometteurs. Dans une seconde partie, nous centrons nos recherches sur une illusion perceptive robuste dans laquelle les participants ont l’impression de « voir » une balle disparaître en l’air : la Vanishing Ball Illusion (VBI). Dans une première étude, nous explorons le rôle du regard du magicien dans la sensibilité à cette illusion. Dans une seconde étude, nous testons l’hypothèse selon laquelle la VBI serait basée sur un effet de Representational Momentum, ce dernier se référant à la tendance des observateurs à "se souvenir" du point d'arrêt d'une scène dynamique de façon décalée dans le sens du mouvement. Dans une troisième partie, nous explorons les mécanismes psychologiques en jeu dans un autre outil très utilisé par les magiciens et peu étudié par la psychologie à ce jour : l’utilisation d’une « fausse solution ». Pour terminer, nous discutons de l’ensemble des résultats et abordons différentes perspectives de recherches qui nous semblent prometteuses dans le domaine de la psychologie de la prestidigitation. / Magicians often trick spectators’ mind by manipulating some of their cognitive limitations. Thus, magic offers an original basis for studying cognitive processes, such as perception, attention, reasoning, etc. In this vein, the present thesis proposes some research that scientifically explores the psychological mechanisms at stake in magic tricks. In the first part of the manuscript, we discuss the interests of an “experimental science of magic” by reviewing the main research from the last century to the present and by presenting some yet unexplored promising areas. In the second part, we focus our research on a robust illusion in which participants ‘‘perceive’’ an imaginary ball disappearing into the air: the Vanishing Ball Illusion (VBI). In a first experimental study, we explore the role of the magician’s gaze in illusion sensitivity. In a second study, we test the hypothesis that VBI could be based on a Representational Momentum effect, the latter referring to the tendency of observers to perceive the stopping point of a moving scene as being located farther ahead in the direction of motion than it really is. In the third part of our manuscript, we explore the psychological mechanisms at stake in another tool often used by magicians and poorly known to psychologists: the use of a “false solution”. Finally, we discuss the overall results and we propose promising research perspectives in the “science of magic”.

This thesis is about the mobilities of geographical knowledge in the material form of lantern-slides and the forces exerted on these by technological and human factors. Owing to its concern with matter, human- and non-human, and its circulation, the thesis addresses the physics of geographical knowledge. The chapters below investigate the Royal Geographical Society’s (RGS) ongoing tradition of telling stories of science and exploration through words, objects and pictures in the final quarter of the nineteenth century and as geography professionalized and geographical science developed. These processes occurred within the context of a plethora of technological innovations, including the combination of the older medium of the magic lantern and photographic lantern-slides, integral to a wide range of entertainment, scientific and educational performances across Britain. In 1886 the RGS began to engage with the magic lantern. Via this technology and the interactive lecture performances in which it featured, I argue that the Society embraced the medium of photography, thereby engendering transformations in methods of knowledge making and to the RGS collections. I study how these transformations influenced the discipline of Geography as it was re-established at the University of Oxford in 1887. I demonstrate the evolution of the RGS’s Evening, Technical and Young Persons’ lectures, their contingent lantern-slide practices and, consequently, how these moulded, and were moulded by, the RGS Fellowship between c. 1885 and 1924. The chapters below explore how these innovations in visual technologies and practices arose, how they circulated knowledge and their effect on geographies of geographical knowledge making. By harnessing the lantern the RGS attracted an expanding and diversifying audience demographic. The thesis demonstrates the interactive nature of RGS lantern-slide lectures and audiences' important role in shaping the Society’s practices and geographical knowledge. The chapters below argue that it was via the use of the lantern that geography was disseminated to new places. The thesis therefore brings additional perspectives and dimensions to understandings of the circulation of geographical knowledge.

Det här arbetet berör frågeställningen kring hur en specifika pitchrörelser i tre generella frekvensområden påverkar hur man uppfattar källan och affekten av magi genom ett interaktivt media. Med hjälp av tidigare forskning kring ljudperception och interaktivt lyssnande i samband med ytterligare research och löpande mindre undersökningar, framställdes en artefakt.Undersökningen omfattade 17 informanter mellan åldrarna 18-50 fördelade mellan en intervju- och enkätbaserad undersökning. De fick interagera med tre olika ljudeffekter och svara på frågor. Skillnaden mellan intervjuerna och enkätundersökningen var att de som deltog i enkäten endast interagerade med en av de tre ljudeffekterna.I resultatet visade det sig att majoriteten av informanterna kunde koppla ljudeffekterna till den ljudkälla de var konceptuellt baserade på. Det visade sig också att ljudeffektens betydelse var mer benägen att förändras beroende på om ljudet var stokastiskt eller deterministiskt. Det ansågs bland annat att en nedåtgående pitchrörelse tillförde en känsla av tyngd i några av ljudeffekterna, och att en uppåtgående rörelse löste upp eller tillförde energi beroende på vilket frekvensområde det påverkade.I en fördjupad version av studien hade både artefakten behövt omfattas och analyseras ur fler perspektiv och av fler involverade, samt innehålla deltagande ifrån en större mängd erfarna och oerfarna lyssnare över ett mer omfattande ålderspann.

Procuramos destacar, a partir dos estudos epistemológicos e metodológicos deles, alguns elementos que podem nos levar a destacar pontos convergentes e divergentes, tentando explorá-los para ressaltar certa aproximação. Para tanto, no primeiro capítulo expomos uma comparação entre religião e magia, levando em conta noções como sacrifício, culto e rito. Essa comparação tem como objetivo mostrar, de um lado, que em Durkheim ambas são fenômenos sociais e que, por outro lado, em Weber a religião se revela mais racional do que a magia, considerada como uma atividade irracional. Portanto, esse capítulo seria uma articulação em torno da natureza social e racional da religião em relação à natureza social e irracional da magia. Já no segundo capítulo buscamos entender melhor, segundo as concepções durkheimiana e weberiana, o sentido da relação que o indivíduo mantém com os seres espirituais objetos de culto, como Alma, Deus e Espírito, para então delimitar o papel desempenhado pelo sagrado na socialização. Por fim, no terceiro capítulo retomamos o debate, ao mesmo tempo velho e atual, sobre as relações complexas entre religião e política. Nesse sentido, mostramos como em Durkheim o caráter indiferenciado desses dois elementos se incorpora e se funde no conceito de religião civil, enquanto em Weber sua diferenciação mais ou menos radical nos leva à sua sociologia da dominação. Com isso buscamos analisar até que ponto a religião e a política podem se influenciar e interagir reciprocamente, mesmo quando elas se opõem. Dessa forma, esse estudo comparativo trata de alguns temas comuns a Durkheim e Weber, mas essencialmente importantes para a sociologia da religião / Abstract: This work, pursuing a very ambitious goal to compare Durkheim and Weber, try to reconcile the two theories of the sociology of religion as they represent the leading figures in the advent of modern Western societies. It seeks to highlight, starting from their epistemological and methodological studies, elements that show us what is convergent and divergent, while trying to exploit them to find an approximation. In order to develop this idea, in the first chapter there is a comparison between religion and magic, taking into account concepts such as sacrifice, worship and ritual. The objective of this comparison is, on one hand, to show that both in Durkheim are a social phenomenon, and, on the other hand, in Weber religion is more rational than the magic considered as an irrational activity. So, this chapter is a joint around the social and rational nature of religion in relation to social and irrational nature of magic. The second seeks to understand better, according to Durkheim and Weber's designs, the meaning of the relationship the individual has with the spiritual beings objects of worship, such as Soul, God and Spirit, as well as to determine the role played by the sacred in the socialization. Finally, the third chapter resumes the debate, in the same time old and current, on the complex relationship between religion and politics. By comparing, we will try to emphasize, first in Durkheim, their indiscriminate nature that incorporates and merges the concept of civil religion, then in Weber, their differentiation more or less radical which is rooted in its sociology of domination. In this sense, we will see through these two leading sociologists extent how religion and politics can influence each other and interact, even if they disagree. Thus, this comparative study discusses some common themes between Durkheim and Weber, which are essentially important for the sociology of religion / Mestrado / Sociologia / Mestre em Sociologia

Abstract  In 1924 an investigation into the poor relief of the Saamis in Sweden was conducted. Thus, non-reindeer herding Saamis came into the lime-light for the first time. Previous research has focused on reindeer-herding Saamis in the sense that they were “the true Saamis”. Instead, the aim of this thesis, is to disclose how the non-reindeer herding Saamis were constructed by using a discourse analysis approach. It includes those called Parish Lapps, found in thirty replies to a questionnaire of the Nordic Museum in Sweden conducted in 1945. The bias presented there included the magic abilities of the Saamis. The findings illustrate that these notions, as well as the official discourse, influenced the communal discourse. Other bias exist in Swedish society today, and previous special rights of reindeer-herding is brought to the fore onto the political agenda, leaving the non-reindeer herding Saamis, and their history, on the margins. The non-reindeer herding Saamis were depicted as “the other”, not fully included in the “true Saami” way of living, always in exclusion to the Swedish residential manner.

This study examines pedagogical patterns associated with wizard, witch, and fairy archetypes in fantasy literature. The fact that magic exists in fantasy literature as a mysterious and elusive element allows narratives to maintain and validate various means of knowledge acquisition – one archetypal form, such as a wizard, pursues a radically different mode of pedagogical engagement with magic than another archetypal form, such as a fairy. According to Carl Jung, archetypes are anchored by ancient elements of mythological lore, yet continuously shape-shift in the present day. My qualitative research process involved close readings of selected passages in popular works of fantasy literature, selected for analysis based on their salient educational themes as well as a presence of witches, wizards, and fairies. I examine how archetypes in fantasy literature frame various approaches to education, investigating whether these pedagogical multiplicities tend to re-codify magic itself. I investigate how these archetypes acquire, dispel, manipulate, and embody magic with opposing or unique tactics, while considering how each archetype confronts the unknown. I also reflect on the relevant folkloric and mythic dimensions of each archetype, examining the extent in which the magical discourse surrounding each archetype relates to ideas about teaching and learning. Each archetype presents pedagogic nuances, subtle parallels, layers, and metaphorical veins of meaning. How does education in fantasy literature establish broad and vexing challenges to the realities that we are familiar with or conscious of in the everyday contemporary educational field? Are there idiosyncratic pedagogical possibilities (and impossibilities) through archetypal representations in fantasy literature, allowing for multifaceted and meaningful representations of teaching and learning? I find that each archetype’s distinct pedagogical model includes variations as well as overlapping representations of creative agency, amplified possibilities, enhanced notions of growth, radical receptivity, calls for empathy, and visions of transformation. After examining each archetype in consecutive chapters, my conclusion summarizes the prismatic meaning of their pedagogical engagements, while reflecting on the implications and cross-pollination of education and magic. The intersection of praxis and knowledge for each archetype induces a mythopoeic imagination in relation to education, as each reconciles and renews significant transformational elements of pedagogy.

Purpose: This study focuses on describing and explaining Djinn, Iblis and magic from an Islamic point of view. There are many stories that can be told but the author focuses on the parts of the stories that is known to the majority of Muslims. One of the many interesting aspects studied in the essay is how people in Babylon, in contrast to today's Muslims, view Islam's interpretation of magic and Djinn.  In order to present these perspectives and their change over time, a number of Muslims are interviewed of various religious backgrounds, liberal, conservative and orthodox. In addition, various studies are used that describe the social structure in Babylon where witchcraft according to Islam was first taught. The information from these works is intertwined with Carl Gustav Jung's and Marie-Louise von Franz's book Man and his Symbols (1964). These studies, together with the interview results, provide the opportunity to compile logical conclusions.  Method: The first two questions are about explaining what Djinn is based on the general Islamic interpretation and who Iblis are. In order to be able to present this information in the results section, the author starts from the qualitative method, intertextuality, which is about texts always being based on previous writings.  The second sub-result focuses on describing what Sihr (Magic) is from an Islamic perspective. It also describes how these rituals are performed. For this, a multimodal method is used to analyze the book Shams al-maarif al-Kubra.  The third sub-result focuses on an analysis of various interviews conducted to create an understanding of how Muslims view Djinn and Sihr. The answers to these are then related to the perception of this in ancient Babylon. A conversation analysis is performed to analyze the interviews.  Theory: In this study, the result is intertwined with the theory (Socialization). Social construction includes human reality. A society is created through interaction between individuals. This is called externalization. The natural character that is then added to a society takes place through objectification. Individuals who apply to the specific society may then accept and integrate with the independent character of society, which at this stage, has been normalized and assumed to be natural.  Result: The result of this study is threefold. According to Islam, Djinn are invisible spirits that God created from poisonous, smokeless fire. Iblis, also known as Lucifer or Satan, is part of the Djinn kin. According to the story, he refused to bow down to Adam, challenged God and thus plays an important role in man's cosmic destiny. According to Islam, magic is rituals performed to make contact with evil Djinn who in turn performs various services for the magician. The services are not provided free of charge. Magicians must perform certain rituals which, according to Islamic tradition, are extremely serious sins. The book Shams al-Maarif al-Kubra teaches readers how to perform certain rituals and draw magical symbols. The third result focuses on compiling data from the interviews conducted that are presented under appendices. Religion was of paramount importance to the Babylonians and formed a large part of their daily lives. In comparison with today's Muslims, it can be stated that they find it more difficult to live by the idea that there are constantly invisible beings and forces around them.

The main goal of this thesis is to obtain lateral parameters of the Magic Formula tire model of a tire commonly used in Formula Student competition. Both the author and the supervisor of the thesis know the tire name and its specification, but the research company that did the tire testing and provided me with the date prohibits sharing this of data publicly, so the tire designation is not mentioned in this thesis. The first chapter covers main theoretical facts related to a tire, briefly describes some of the tire models and shows possibilities how to determine tire characteristics that are used in a tire model. The thesis describes how to process raw tire data measured during a laboratory experiment using scripts created in Matlab software. The inputs variables are slip angle, lateral force, normal force and inclination angle. Raw data are splitted into parts, main coefficients of the Magic formula model (B, C, D, E, Sh, Sv) are calculated and subsequently the lateral parameters are obtained using least square method to fit parameters into the measured data. The works gives two main outcomes. The first output is a set of Matlab scripts that can be used to determine lateral parameters of any tire that has the same input data format as presented. A TIR file of the Formula Student tire in case of lateral slip is the second result of the work. This can be used for vehicle dynamics simulation of Formula Student racing car. The thesis also offers a comparison between parameters, which I calculated, and those gained thanks to Optimum Tire software by Calspan research company. Additionally the work shows the effect of load and inclination angle on lateral force.

Afin de sonder la persistance de la fermeture de couches à N=50 pour les isotopes de nickel, une expérience a été réalisée au RIBF (RIKEN, Japon) pour produire des noyaux autour du ⁷⁸Ni par fission en vol d'un faisceau de ²³⁸U. Les spectromètres BigRIPS et ZeroDegree ont été utilisés pour la purification et la sélection des noyaux d'intérêt. La décroissance de ces noyaux a été observée avec le dispositif EURICA pour la détection des rayonnements gamma, couplé avec le détecteur à particules chargées WAS3aBi.L'analyse des corrélations entre l'implantation des ions ⁷⁹′⁸⁰Cu et leur décroissance, ainsi que les spectres de décroissance gamma en simple et double coïncidence, nous ont permis de proposer un schéma de niveaux excités pour le ⁷⁹Zn, avec assignation de spin et parité pour la plupart des états. Nous avons aussi mis une contrainte entre 3hbar et 5hbar sur la valeur du spin de l'état fondamental du ⁸⁰Cu. La comparaison avec un modèle schématique de couplage cœur-particule nous a permis d’interpréter le schéma de niveau et de proposer des hypothèses sur la nature des états observés. Les énergies des états de particule individuelle extraites du calcul théorique indiquent la persistance du gap N=50 à Z=28. / In order to investigate the persistence of the N=50 gap for the Nickel isotopes, an experiment has been performed at RIBF (RIKEN, Japan) to produce exotic nuclei around ⁷⁸Ni by in-flight fission of a ²³⁸U beam. The BigRIPS and ZeroDegree spectrometers were used to purify and select the nuclei of interest. Their decay was detected with the EURICA detector for γ-ray detection, coupled with the charged particle WAS3aBi detector. The analysis of the correlations between the ion implantation and their decay, as well as the γ decay spectra in simple and double coincidence allowed us to propose a level scheme of the excited states for the ⁷⁹Zn, and we assigned the spin and parity for most of the states. We also constrained the spin value for the fundamental state of the ⁸⁰Cu, between 3hbar and 5hbar. Comparison with a core-particle coupling model allowed us to interpret the level scheme and propose hypothesis about the nature of the observed states. The single particle state energies extracted from the theoretical calculation indicate the persistence of the N=50 gap at Z=28.

Im Fokus des vorgestellten Projektes steht die Untersuchung der Verwendung von zwei ägyptischen Kursivschriften in einem homogenen Textkorpus. Hierbei handelt es sich zum einen um Hieratisch, einer Kursivschrift, die etwa zeitgleich mit den Hieroglyphen im 3. Jtd. v. Chr. entstand und für Texte auf Papyrus verwendet wurde. Mit beiden Schriftarten wurde in der Regel dieselbe Phase der ägyptischen Sprache geschrieben. Zum anderen um Demotisch, einer um 650 v. Chr. entwickelten Kursivschrift, die ebenfalls für Texte auf Papyrus verwendet wurde, und eine historisch jüngere Sprachstufe beschreibt. Beide Schriftsysteme erscheinen nebeneinander in den vier magischen Papyri der sog. „Theban Magical Library“ aus dem 3. Jhd. n. Chr., die sich heute in London, Leiden und Paris befinden. Das zu untersuchende Textkorpus umfasst etwa 157 Einzeltexte, die sich auf mehr als 1700 Zeilen Text verteilen. Ein Großteil der Texte ist in demotischer Schrift und Grammatik geschrieben. Daneben finden sich einige Passagen in hieratischer, griechischer und in einer Zauberschrift. Auch sprachliche sind die Texte keineswegs homogen. Kürzere Passagen weisen häufig eine ältere Sprachstufe als das Demotische auf. Auch die Schriftart kann innerhalb eines Satzes, in einigen Fällen sogar innerhalb eines Wortes, wechseln. Die Gründe für die Verwendung von demotischer und hieratischer Schrift sind bisher nicht untersucht worden. Da die einzelnen Sprüche auf unterschiedliche Vorlagen aus verschiedenen Kulturkreisen zurückgehen, liegt der Schwerpunkt des Vorhabens auf der Untersuchung der Beziehung von Schriftart, Sprache oder Sprachstufe und Inhalt. Bisher wird in der Forschung davon ausgegangen, dass hieratische Schrift zur Schreibung von Götterbezeichnungen oder bestimmter Termini, bevorzugt also bei Passagen mit religiösem Inhalt Verwendung fand. Jüngere Überlegungen konnten jedoch zeigen, dass hieratische Schrift in einigen Fällen mit sprachlich altertümlichen Merkmalen einhergeht, wobei es sich wohl um die Reste eines Vorläufers handelt, der nicht vollständig in demotische Schrift und Sprache übertragenen wurde. Um das Quellenmaterial adäquat zu untersuchen, ist eine genaue Analyse von Schrift, Sprache und Inhalt der Einzeltexte nötig. In einem ersten Schritt wird jeder Papyrus unabhängig von den anderen untersucht. Hierfür wird der Text in eine Excel-Tabelle aufgenommen. Jeder Eintrag wird mit verschiedenen Merkmalen versehen, die für die spätere Auswertung von Bedeutung sind. Die Texte werden in Hinblick auf die verwendete Schriftart, Sprachstufe, der zeitlichen Bezeugung eines Wortes oder grammatikalischen Konstruktion, Wortart, Herkunft (ägyptisch, griechisch, jüdisch etc.), Kontext (Vorkommen in Titeln, direkter Rede u. ä.) und, falls vorhanden, Anmerkungen des Schreibers analysiert. In einem ersten Schritt werden die Texte in ägyptologischer Umschrift in eine Exceltabelle eingetragen. Hierbei erhält jedes Wort einen Eintrag und wird mit den für die Analyse benötigten Merkmale versehen. Im Anschluss wird die Tabelle in eine mySQL Datenbank eingelesen. Diese wurde in Zusammenarbeit mit Dr. C. Riepl von der IT-Group Geisteswissenschaften der LMU München erstellt. Anhand dieser Datenbank erfolgt die Analyse der Texte.
