This paper explores the reasons why Bilali Mohammed, a Muslim slave who lived on Sapelo Island produced his Arabic document, known as the Ben Mi diary. Although several scholars have studied the document, they have remained silent on why Bilali was literate and why he produced this work. Since the Ben Au diary deals with Islamic ritual, this paper argues that in order to understand the text it must be intimately connected to Bilali’s life in West Africa, and, more specifically, to the spread of religious school during a period of Islamic revival in the eighteenth and nineteenth centuries. One of the central concerns of this paper is to raise questions about Muslim slave identity, resistance and literacy. It seeks to situate the discussion about the Ben Ali diary in the larger context of African American and American history. While the paper explores the literature on Muslim slaves, it also explores why the historical narratives that scholars produce about America’s past silence Islam. Finally, it investigates issues around power and narrativity, and suggests that Islam has been present in the New World since the onset of European colonialism. Consequently, it argues that present-day discourse about the foreignness and “dangers” of Islam in the West, make little sense, and are only legitimized by a complete disregard of this Muslim past.

Nineteenth-century British authors, in particular, Charles Dickens, Charlotte Bronte, and Jane Austen, often turned to orphaned children as a means to drive the plot of their novels. While struggles such as displacement were often accurately depicted, the abovementioned authors and their contemporaries often glossed over or completely disregarded the trauma and psychological implications felt by these orphans. As psychology gained prominence as a discipline through the works of Sigmund Freud and others, modern British literature saw a shift in its consideration of orphans and, additionally, emotionally absent mothers. This thesis will examine three modern British novels; Ian McEwan’s Atonement, Kate Atkinson’s Behind the Scenes at the Museum, and Graham Swift’s Waterland with respect to their exploration of the psychological and possible traumatic impact of their protagonists lives in a variety of disrupted family dynamics.

The aim of the study is to examine how religion legitimates outrages and it what ways we can regard religion as politics. The study uses the theory that Eickelman and Piscatori present in their book Muslim politics. They use the term ‘Muslim politics’ to describe the relation between Islam and politics. Eickelman and Piscatori divide Muslim politics in five elements that the essay uses to structure the analysis. By studying IS´s own published documents, two issues of the newspaper Dabiq Magazine, from a discourse analytical approach, this essay aims to consolidate the discourse behind the texts and find how the Muslim politics of IS is constructed. IS is an organization that has proclaimed a caliphate that includes Iraq and Syria. IS claims that the core of Islam has been lost and it needs to be rediscovered to avoid the punishment from Allah. IS claim to be the trustees of the will of Allah on earth and call on people to rally behind their interpretation of “true Islam”. The vision of IS is to re-establish a caliphate which is part of the ongoing objectification process.

L'étude du portrait de la femme maghrébine dans trois romans de Ben Jelloun révèle trois vies d'enfant, d'adolescente et de femme très différentes quant à la condition féminine. Il y a une émancipation progressive entre les portraits qui peut s'expliquer par le fait que les romans se déroulent dans des cultures et à des époques différentes, mais aussi par les intentions féministes de l'auteur.
The study of the image of the Maghrebi woman in three novels of Ben Jelloun reveals three very different kinds of childhood, adolescence and adult lives. There is a progressive emancipation between the portraits, which is partly due to the differences in time and setting, but also to the feminist intentions of the author.

Louis Delaporte est un personnage méconnu de l’histoire de l’étude de l’art khmer en France. Il a cependant occupé, entre sa première mission aux ruines khmères, en 1873, et sa démission du Musée indochinois du Trocadéro, en 1924, une place centrale dans l’archéologie de l’Asie du Sud-Est. Cette thèse fournit un premier éclairage sur le travail entrepris par Delaporte pour faire connaître l’art khmer, et constituer une collection d’œuvres devant servir de base pour son étude. Des sources inédites (correspondance familiale, documents de travail conservés par la famille Delaporte et le musée Guimet) permettent de retracer le parcours professionnel de Louis Delaporte, de sa première visite sur le site d’Angkor, en 1866, au développement du Musée indochinois du Trocadéro, entre 1884 et 1924. Si la concentration du travail de Delaporte autour de l’art khmer est fortuite (sa première mission aux ruines khmères a ainsi été conçue comme l’étape initiale d’un voyage plus large d’exploration du Tonkin), il développe cependant dès son retour en France une stratégie réfléchie pour assurer aux œuvres rapportées de son séjour une place de choix sur la scène scientifique française. Grâce à la création d’un très vaste réseau, dans l’administration aussi bien que dans les milieux scientifiques, Louis Delaporte devient ainsi, dès les années 1880, un personnage incontournable dans l’étude des monuments khmers. Faute des connaissances nécessaires, il ne réussira cependant jamais à s’imposer comme le fer de lance de l’archéologie khmère, et se concentrera plutôt sur le développement d’une collection destinée à devenir, en France, indispensable à qui s’intéresse à l’archéologie khmère
Louis Delaporte is an underrated character in the history of the study of Khmer art in France. Between his first travel to the Khmer ruins, in 1873, and his resignation from the Musée indochinois du Trocadéro, in 1924, he held, however, a central position in the archeology of Southeast Asia. This thesis provides a first insight into the work undertaken by Delaporte to make Khmer art renowned, and provide a collection of art works meant to be the basis of its study. Unpublished sources (family letters, working papers kept by the Delaporte family and the musée Guimet) help relate Louis Delaporte’s career, from his first visit to Angkor, in 1866, to the development of the Musée indochinois du Trocadéro, between 1884 and 1924. If the focus of Delaporte’s work on Khmer art is born of fortuitous circumstances (his first travel to the Khmer ruins was designed to be the inital step of a broader exploration trip to Tonkin), he however developed a conscious strategy to ensure the works of art he brought back became prominent in French scientific circles. Thanks to the creation of a vast network, in the administration as well as in scientific circles, Louis Delaporte became, in the 1880s, a key character in the study of Khmer monuments. Due to his lack of knowledge, however, Delaporte never succeded in becoming the spearhead of Khmer archeology, and focused instead more on the development of a collection designed to become, in France, essential to whoever had an interest in Khmer archeology

The diploma thesis describes the design and assessment of steel structure of the roofing of the military museum in Králíky. The supporting structure of hall is 40.00 meters span.

Part of the report is open-air roofing.

Diese Arbeit bietet eine solide theoretische Grundlage zu Philanthropie und religiös motivierten Spendenaktivitäten und deren Einfluss auf Wohltätigkeitstrends, Entwicklungszusammenarbeit und einer auf dem Gedanken der sozialen Gerechtigkeit beruhenden Philanthropie. Untersucht werden dafür die Strukturen religiös motivierte Spenden, für die in der islamischen Tradition die Begriffe „zakat“, „Waqf“ oder im Plural auch „awqaf-“ oder „Sadaqa“ verwendet werden, der christliche Begriff dafür lautet „tithes“ oder „ushour“. Aufbauend auf diesem theoretischen Rahmenwerk analysiert die qualitative und quantitative Feldstudie auf nationaler Ebene, wie die ägyptische Öffentlichkeit Philanthropie, soziale Gerechtigkeit, Menschenrechte, Spenden, Freiwilligenarbeit und andere Konzepte des zivilgesellschaftlichen Engagements wahrnimmt. Um eine umfassende und repräsentative Datengrundlage zu erhalten, wurden 2000 Haushalte, 200 zivilgesellschaftliche Organisationen erfasst, sowie Spender, Empfänger, religiöse Wohltäter und andere Akteure interviewt. Die so gewonnen Erkenntnisse lassen aussagekräftige Aufschlüsse über philanthropische Trends zu. Erstmals wird so auch eine finanzielle Einschätzung und Bewertung der Aktivitäten im lokalen Wohltätigkeitsbereich möglich, die sich auf mehr als eine Billion US-Dollar beziffern lassen. Die Erhebung weist nach, dass gemessen an den Pro-Kopf-Aufwendungen die privaten Spendenaktivitäten weitaus wichtiger sind als auswärtige wirtschaftliche Hilfe für Ägypten. Das wiederum lässt Rückschlüsse zu, welche Bedeutung lokale Wohltätigkeit erlangen kann, wenn sie richtig gesteuert wird und nicht wie bislang oft im Teufelskreis von ad-hoc-Spenden oder Hilfen von Privatperson an Privatperson gefangen ist. Die Studie stellt außerdem eine Verbindung her zwischen lokalen Wohltätigkeits-Mechanismen, die meist auf religiösen und kulturellen Werten beruhen, und modernen Strukturen, wie etwa Gemeinde-Stiftungen oder Gemeinde-„waqf“, innerhalb derer die Spenden eine nachhaltige Veränderung bewirken können. Daher bietet diese Arbeit also eine umfassende wissenschaftliche Grundlage, die nicht nur ein besseres Verständnis, sondern auch den nachhaltiger Aus- und Aufbau lokaler Wohltätigkeitsstrukturen in Ägypten ermöglicht. Zentral ist dabei vor allem die Rolle lokaler, individueller Spenden, die beispielsweise für Stiftungen auf der Gemeindeebene eingesetzt, wesentlich zu einer nachhaltigen Entwicklung beitragen könnten – und das nicht nur in Ägypten, sondern in der gesamten arabischen Region. Als konkretes Ergebnis dieser Arbeit, wurde ein innovatives Modell entwickelt, dass neben den wissenschaftlichen Daten das Konzept der „waqf“ berücksichtigt. Der Wissenschaftlerin und einem engagierten Vorstand ist es auf dieser Grundlage gelungen, die Waqfeyat al Maadi Community Foundation (WMCF) zu gründen, die nicht nur ein Modell für eine Bürgerstiftung ist, sondern auch das tradierte Konzept der „waqf“ als praktikable und verbürgte Wohlstätigkeitsstruktur sinnvoll weiterentwickelt.
This work provides a solid theoretical base on philanthropy, religious giving (Islamic zakat, ‘ushour, Waqf -plural: awqaf-, Sadaqa and Christian tithes or ‘ushour), and their implications on giving trends, development work, social justice philanthropy. The field study (quantitative and qualitative) that supports the theoretical framework reflects at a national level the Egyptian public’s perceptions on philanthropy, social justice, human rights, giving and volunteering and other concepts that determine the peoples’ civic engagement. The statistics cover 2000 households, 200 Civil Society Organizations distributed all over Egypt and interviews donors, recipients, religious people and other stakeholders. The numbers reflect philanthropic trends and for the first time provide a monetary estimate of local philanthropy of over USD 1 Billion annually. The survey proves that the per capita share of philanthropy outweighs the per capita share of foreign economic assistance to Egypt, which implies the significance of local giving if properly channeled, and not as it is actually consumed in the vicious circle of ad-hoc, person to person charity. In addition, the study relates local giving mechanisms derived from religion and culture to modern actual structures, like community foundations or community waqf that could bring about sustainable change in the communities. In sum, the work provides a comprehensive scientific base to help understand- and build on local philanthropy in Egypt. It explores the role that local individual giving could play in achieving sustainable development and building a new wave of community foundations not only in Egypt but in the Arab region at large. As a tangible result of this thesis, an innovative model that revives the concept of waqf and builds on the study’s results was created by the researcher and a dedicated board of trustees who succeeded in establishing Waqfeyat al Maadi Community Foundation (WMCF) that not only introduces the community foundation model to Egypt, but revives and modernizes the waqf as a practical authentic philanthropic structure.

In the past, in the process of promoting cultural and creative products, the most difficult is: How to link cultural creativity with various tourism industry activities? The most important spirit of combining cultural and creative commodities with the tourism industry is that “cultural creativity is the value-added factor or even the core factor of the tourism industry”. Through cultural creativity, it is matched with the direction of tourism development policies of relevant government departments, combined with local cultural tourism, and the overall community construction. The promotion has become a niche for marketing the local tourism industry, strengthening the local visibility and the identity of local residents, gaining more domestic and foreign tourists, and bringing huge economic benefits to the local tourism industry. The focus of many museums today has gradually shifted from the management of “materials” to the services of “people”. That is, in addition to the preservation, research and display functions of traditional collectibles, museums are increasingly focusing on the needs of the general public, such as tourism and leisure services and learning and entertainment education. The Bear Museum combines the rich resources and energy of the tourism and leisure industry with cultural and creative products. It also focuses on the development and operation of many tourism museums. Located in Kansai Town, Hsinchu County, the Bear Museum is the largest collection of teddy bears in Asia and the most abundant collections. It not only has abundant resources and potential for development, but also has its own model of business planning and management. With the trend of globalization, humanity has entered the 21st century. Knowledge has become the greatest asset of mankind, and the knowledge economy has become the most important factor in determining the outcome of this era. Therefore, knowledge is power and products must meet the needs of customers. Innovation and breakthrough have become the focus of management. In simple terms, it is to provide the value of good interaction and special emotional connection between cultural and creative products and tourists. Keywords: Museum, Teddy Bear, Guanxi Town, Hsinchu County, Culture Creative Touris

This research mainly focuses on the local industries in Yunlin and the spirit of the traditional towel industry is conveyed through creating picture books. Data and related literature were collected for reference of creating and studying picture books. The development of the towel industry in Taiwan was described and the relationship between creating picture books and the towel industry was discussed. Collection and analysis of relevant literature were conducted for the theoretical foundation of this research. The purposes of this study are as follows. 1. To explore the process of towel development in Huwei, Yunlin and to search for the elements of creating picture books that can be applied to the local industry. 2. To analyze the contents and values of the picture books for the local industry as well as their forms of expression and creation styles for reference. 3. The development of the towel industry in Taiwan was explored and picture books that were rich in encouragement were created based on the local industry in Yunlin.It took half a year for this creation. The conclusions of this creation are as the following. 1. For the elements of creating picture books for the local industry, the strong local industrial characteristics were incorporated and the creation elements of stories, image presentation, style traits and the local industry were concluded to recall the memories of the readers via actual stories, which were served as the basis of ideation of the text. 2. For the content and value of the picture book for the local industry, overall consideration and conception were required for the structure and layout of the picture book to precisely present the content and value of the picture book for the local industry. Moreover, proper picturized elements were also added to convey the value of the traditional industry through pictures. 3. picture books for the local industry in Yunlin created: pictures and texts were combined in the picture books and their connotation could not be interpreted if separated. Henceforth, words and pictures needed to be considered simultaneously when creating picture books for an overall arrangement. It is expected the creation process of this research may provide a reference to other researchers who are also engaged in creating local picture books.

On account of the rapid changes for modern times in the last decade, people has been gradually forgotten the importance of NPM and the benefit it can bring to us. How to reinvigorate itself and make a renaissance of Chinese culture for the citizen has become an urgent issue for the NPM. Therefore, this study aims to comprehend how consumers generate different product attitudes through different communication methods and provide more authentic insight into the brand management and revitalization of the NPM by two major topics, which are brand resistance and brand aging. We apply both the persuasion resistance effect, which has been widely discussed in the field of psychology and the market orientation strategy, brand-oriented strategy in integrated marketing communication., We divided the study into two experimental designs, the first one is the manipulation of 2 (the spokesperson type: Yongzheng vs. Genghis Khan) x 2 (endorsement strategy: explicit vs. hint) for verifying that the young consumers do not tend to resist to the NPM. In the second experiment, we take the 2 (product type :market-oriented creative cup set, brand-oriented boutique replica) x 2 (advertising strategy :market-oriented young slogan, brand-oriented standard slogan) experimental design to examine the research hypothesis. We confirm that the combination of the market-oriented strategy advertisement and market-oriented product is significantly better than the market-oriented advertisement combine with brand-oriented products, the fitness effect may improve young consumers’ attitude toward NPM. And accordingly, we raise the relevant suggestion to the NPM.

Si nous pouvons constater, d’une part, que l’univers carcéral occupe une place très importante dans les textes de Tahar Ben Jelloun, nous ne pouvons cependant ignorer, de l’autre, les efforts des personnages de la diégèse ben jellounienne pour trouver une libération quelconque. De ce fait, la libération constitue l’objet de notre étude par excellence. Nous avons choisi cinq textes de l’écrivain marocain : Moha le fou Moha le sage (1978), L’enfant de sable (1985), La nuit sacrée (1987), Cette aveuglante absence de lumière (2001) et Amours sorcières (2003). Après un survol rapide de l’incarcération sous ses différentes formes, allant des plus concrètes aux plus abstraites, nous étudions les paradigmes les plus communs vers lesquels l’homme maghrébin moderne se tourne dans le but de se libérer des carcans qui l’entravent et nous en relevons tour à tour les limitations ou lacunes. Ainsi, nous remettons en question le modèle matérialiste qui échoue pour ce qui de la libération de l’individu en raison de ses excès. Puis, nous étudions le modèle psychologique mettant l’accent sur ses limites dans la mesure où il comprend un mouvement vertical vers le bas. Or, sans un mouvement vers le haut, aucune libération n’est possible. Très particulière à la société maghrébine est la praxis islamique moderne qui, loin de libérer l’individu, ne fait que l’étouffer davantage. Ensuite, nous soulevons des questions au sujet de la sorcellerie et des dangers qu’elle comprend. Loin d’être un élément libérateur, elle constitue un piège. Nous arrivons éventuellement à la seule clé capable d’apporter la libération intérieure au Maghrébin : la métaphysique et, dans le contexte de la civilisation arabo-islamique, il s’agit de l’ésotérisme islamique ou le soufisme. Ce mémoire requiert une approche très scientifique telle que l’exige la nature même de notre problématique. Nous avons opté pour une approche métaphysique pour conduire notre étude à bon port.
If we cannot deny the fact that the realm of incarceration holds an important place in the texts of Tahar Ben Jelloun, we also have to acknowledge the endeavours of the characters to find liberation in some way or another. Therefore, above all else, liberation constitutes the object of our study. We have chosen five texts of the Moroccan author: Moha le fou Moha le sage (1978), L’enfant de sable (1985), La nuit sacrée (1987), Cette aveuglante absence de lumière (2001) and Amours sorcières (2003). After a quick glance at the different forms of incarceration, starting from the most tangible and moving to the most abstract ones, we study the most common paradigms to which the Moroccan turns to in order to free himself from the shackles that imprison him and we study simultaneously their shortcomings. Hence, we call into question the materialistic model that fails in liberating the individual on account of its excesses. Then, we study the psychological model laying emphasis on its limitations in that it comprises a vertical downward movement while no liberation is possible without an upward movement. Quite specific of the Moroccan society is the modern Islamic praxis that, in lieu of freeing the individual, only stifles him more. Afterwards, we raise questions concerning sorcery and dangers that it represents. Far from being a liberating agent, it constitutes a trap. Ultimately we come to the only key capable of bringing internal liberation to the Moroccan: metaphysics and, in the arabo-islamic context, it is Islamic esotericism or Sufism. This thesis requires a most scientific approach as demands the very nature of our problematic. We have thus chosen a metaphysical approach that best suits our study.

Binaural beats (BBs) are auditory illusions created by the brain when two coherent sounds with slightly different frequencies are presented to both ears dichotically. For example, if the subject is presented a 256 Hz tone to the right ear and a 250 Hz to the left ear, the beat in this phenomenon is referred to as a 6 Hz theta binaural beat. Conversely, a mix of two sinusoids presented to the same ear is called acoustic beat (AB), resulting in a periodic amplitude fluctuation. Although BBs were shown to have positive effects on cognition, there are no sufficient studies on BBs and episodic memory. Furthermore, there is no agreement to explain the brain mechanism underlying the perception of BBs. The primary goal of this study is to investigate the influence of BBs on episodic memory and the effects of BB stimulation on brain rhythms, more concretely to examine whether they can change the power of specific EEG frequencies, comparatively to ABs. The secondary objective focuses on an exploratory study to measure cortical auditory evoked potentials (CAEPs) applying Muse, a consumer-grade EEG device used in this study, in order to assess its potential and the corresponding data quality. To meet the goals, two separate experiments were designed: a classic CAEP paradigm, with a total of 5 participants (3 male, 2 female; aged 22-25 years old); and an experiment with 32 subjects (19 male, 13 female; aged 20-28 years old), divided into two groups (depending on type of stimulation performed: 20 Hz beta or 6 Hz theta beats), each one with two stimuli conditions (BB or AB), received 15 minutes before the episodic memory task, during memory encoding phase and during the free recall test, across 2 sessions with an interval of 1 week. To quantify the power of brain oscillations during AB and BB stimulation, time-frequency analysis was performed using Discrete Wavelet Transform (DWT) and Relative Wavelet Energy (RWE). Regarding CAEP paradigm, N1-P2 complex was detected in temporal regions with acceptable signal-to-noise ratio. Parametric and non-parametric paired t-tests showed several significant changes in RWE values within each group at different time points, frequency bands and channels during both sessions, between BB and AB conditions. Moreover, entrainment of brain activity with the frequency of the beat was detected within theta BB stimulation. Regarding the effects of BB stimulation on episodic memory performance, t-tests revealed significant differences in the memory scores between AB and BB conditions during the first session (t=−2.48, p=0.0133) and second session (t=−2.67, p=0.00914) in theta group, with higher scores observed after BB stimulation. In beta group, significant differences in the scores were observed between AB and BB conditions during first session (t=−2.40, p=0.0154), with higher scores registered in BB condition. Inter-group analysis demonstrated that beta group outperformed theta group in both AB (t=3.37, p=0.00244) and BB (t=3.58, p=0.00143) conditions during the second session. This study validates the use of Muse for neuroscientific research, demonstrating that is possible to rely on consumer-grade low-cost EEG systems. Furthermore, it demonstrates that 20 Hz beta and 6 Hz theta BBs have a positive influence on episodic memory performance. Based on findings of positive effects of BBs on cognition, these results were expected. Entrainment was observed during theta BB stimulation. In addition, it is suggested that BBs have a modulatory effect on brain frequencies, with involvement of dynamical processes.
Batimentos binaurais (BBs, do inglês Binaural beats) são ilusões auditivas criadas pelo cérebro quando dois sons coerentes com frequências ligeiramente diferentes são apresentados dicoticamente, isto é, cada ouvido é estimulado por frequências diferentes. Existem diferentes tipos de BBs, dependendo das frequências a partir das quais são criados e da diferença entre elas, o que determina a frequência do batimento. Por exemplo, se o sujeito é apresentado com um tom de 256 Hz no ouvido direito e 250 Hz no ouvido esquerdo, cria-se um batimento binaural de 6 Hz, na frequência do ritmo teta. Por outro lado, a mistura de duas sinusoides apresentadas ao mesmo ouvido possui o nome de batimento acústico (AB, do inglês acoustic beat) e as suas interferências são refletidas em flutuações periódicas em amplitude. Estudos demonstram que os BBs têm um efeito positivo na memória de trabalho, memória de longo prazo, capacidade de atenção e nos níveis de ansiedade e relaxamento. No entanto, existem relatos do seu efeito negativo na atenção e na memória de curto prazo. Para além disso, não existe um consenso na comunidade científica para explicar o mecanismo cerebral subjacente à perceção dos BBs. Tudo isto sublinha a necessidade de mais unificação na pesquisa. Apesar do efeito benéfico dos BBs nos diferentes tipos de memória, não existe um leque de estudos suficientemente grande relativamente à sua influência na memória episódica, um tipo de memória associado à codificação de eventos autobiográficos. Destaques na pesquisa sugerem que as oscilações teta estão associadas a um melhor desempenho na memória episódica. Presumindo que a estimulação auditiva com BBs teta possa ter um efeito modulador das frequências cerebrais por meio de resposta pós-frequência, mais especificamente no ritmo teta, é razoável supor que os BBs podem influenciar a memória episódica. O sistema de EEG usado neste estudo é o Muse, desenvolvido para ajudar em técnicas de meditação. Como não se trata de um aparelho de grau médico, é necessário entender se o material é viável para o estudo. O método para alcançar esta validação foi medir os potenciais evocados auditivos corticais, uma resposta cerebral já bem conhecida. Posto isto, a primeira parte desta tese foca-se num estudo exploratório para medir os potenciais evocados auditivos corticais usando o Muse, com o objetivo de avaliar o potencial do dispositivo e a qualidade dos dados correspondentes. A segunda parte e a meta principal deste estudo é investigar a influência do BBs na memória episódica e estudar o seu efeito nas oscilações cerebrais, em comparação com ABs. Para concretizar a primeira experiência deste estudo, um paradigma clássico foi desenhado para medir os potenciais evocados. Um total de 5 voluntários participaram neste estudo, com idades compreendidas entre 22 e 25 anos. Os participantes receberam um total de 180 estímulos, que consistiam em tons puros de 1000 Hz, com 500 ms de plateau, 10 ms de subida e descida e apresentados a cada 2 segundos. A aquisição do EEG e os marcadores de evento foram concretizados através do Lab Streaming Layer, uma ferramenta que permite criar redes de conexões entre vários dispositivos e programas. O pré-processamento e o processamento dos dados foram executados no EEGLAB, uma extensão do MATLAB que oferece uma interface gráfica para realizar a análise do EEG. Os resultados obtidos foram satisfatórios: o complexo N1-P2 foi identificado em todos os sujeitos e também nas curvas de grande média, com uma melhor relação entre o sinal e o ruído comparativamente às curvas individuais. Relativamente à segunda parte desta tese, a experiência consiste em 2 grupos de sujeitos, 2 blocos de tarefas, cada um com 2 condições de estímulo (AB ou BB), concretizada durante 2 sessões, separadas por uma semana. Um total de 32 voluntários foram recrutados, com idades compreendidas entre 20 e 28 anos. Os sujeitos foram divididos em 2 grupos: grupo teta, que recebeu estimulação com BBs e ABs teta na frequência dos 6 Hz, criados a partir de tons puros de 247 Hz e 253 Hz; grupo beta, que foi estimulado com BBs e ABs beta na frequência dos 20 Hz, gerados a partir de tons puros de 240 Hz e 260 Hz. A primeira parte do primeiro bloco consistia numa tarefa passiva em que os sujeitos de cada grupo ouviam ABs durante 15 minutos, ao mesmo tempo em que aquisição do EEG era realizada. Seguiu-se uma tarefa de memória episódica, em que os participantes tinham que decorar uma sequência de 30 imagens de objetos, cada uma com a duração de 3 segundos. De seguida, uma tarefa de distração foi realizada consistindo numa contagem em voz alta de 20 até 0. Por fim, foi feito um teste de recordação livre em que os sujeitos apontavam num papel os objetos que se lembravam de ver, cujo número seria contabilizado como pontuações de memória. O segundo bloco de tarefas é idêntico ao primeiro, exceto que imagens de objetos diferentes foram usadas e a estimulação durante os 15 minutos iniciais foi feita com BBs. Na segunda sessão, os mesmos procedimentos foram repetidos, exceto o uso de imagens de objetos diferentes em cada bloco. Para quantificar a energia de cada banda de frequência do EEG, recorreu-se à Transformada de Wavelet Discreta, que decompõe o sinal em vários níveis, cada um correspondendo a uma banda de frequência de ritmos cerebrais, e à Energia de Wavelet Relativa (RWE, de Relative Wavelet Energy). Mudanças na RWE dum determinado nível de decomposição refletem mudanças na atividade cerebral na banda de frequências correspondente. Dois tipos de análise foram concretizados: um tendo conta a evolução temporal da RWE ao longo de 13 segmentos de 1 minuto; o segundo implicou calcular a RWE média ao longo de um único segmento de EEG, colapsando a dimensão temporal. Os testes t paramétricos e não paramétricos revelaram várias diferenças entre os valores de RWE durante a estimulação com ABs e a estimulação com BBs, ao longo de diferentes instantes de tempo, bandas de frequências, canais e sessões da experiência. Relativamente ao grupo teta, os testes revelaram que a RWE na banda de frequência alfa no canal AF8 durante a primeira sessão aumentou de AB para BB (t=2.2701, p=0.01919). Durante a segunda sessão, foi observado um aumento dos valores de RWE na banda de frequências teta no canal TP10 da condição AB para BB (t=2.4509, p=0.0135). Relativamente ao grupo beta, as seguintes observações correspondem à primeira sessão, da condição AB para BB: uma diminuição significativa de RWE na banda de frequências beta no canal TP10 (t=-2.3364, p=0.0181) e um aumento significativo de RWE na banda delta no canal TP10 (t=4.3193, p=0.0004164) e no canal TP9 (t=2.7144, p=0.00885). Quanto aos efeitos dos BBs na performance de memória episódica, os testes t revelaram diferenças significativas nas pontuações entre as condições AB e BB durante a primeira sessão (t=-2.48, p=0.0133) e segunda sessão (t=-2.67, p=0.00914) no grupo teta, com pontuações mais altas observadas após a estimulação com BB. No grupo beta, diferenças significativas nas pontuações foram observadas entre as condições AB e BB durante a primeira sessão (t=-2.40, p=0.0154), com pontuações mais elevadas registadoa na condição BB. A análise entre os grupos demonstrou que o grupo beta superou o grupo teta em ambas as condições AB (t=3.37, p=0.00244) e BB (t=3.58, p=0.00143) durante a segunda sessão. Uma análise fatorial ANOVA II demonstrou que o efeito principal da condição foi significativo, sendo que os participantes que foram submetidos à estimulação com batimentos binaurais tiveram resultados mais altos (F(1,115)=5.49, p=0.0208). O efeito principal da sessão também foi significativo, com pontuações mais altas obtidas durante a segunda sessão (F(1,115)=9.206, p=0.00298). Houve interação significativa entre grupo e sessão (F(1,115)=5.11, p=0.0256). Para além disso, regressões lineares demonstraram que o aumento das pontuações de memória está associado ao aumento de RWE na banda de frequências beta (F(5,114) = 5.876, p < 0.0001). Este estudo mostra que é possível quantificar os potenciais evocados auditivos corticais usando um dispositivo de EEG de grau de consumidor. Foi demonstrado que os batimentos binaurais teta de 6 Hz e beta de 20 Hz têm efeito positivo no desempenho da memória episódica, comparativamente aos respetivos acoustic beats. Os participantes que foram estimulados com BBs beta tiveram melhores resultados nos testes de memória comparativamente aos que receberam estimulação com BBs teta, o que pode ser explicado pelo facto da atividade teta, característica da memória episódica, ter sido despertada durante a estimulação BB beta. No entanto, foi demonstrado que o aumento nas pontuações de memória episódica é explicado pelo aumento da RWE no ritmo beta. A resposta pós-frequência foi observada durante a exposição aos BBs teta, porém o mesmo não se verifica relativamente aos BBs beta. Para concluir, este estudo prova que os batimentos binaurais são moduladores neuronais, com envolvimento de respostas dinâmicas. Este efeito modulador da atividade cerebral pode ser a razão por trás da influência destes batimentos na memória episódica.
