Materiais bionanocompósitos a base de argilominerais e hidróxidos duplos lamelares como sistemas de liberação de fármacos

Bionanocomposites systems clay base (montmorillonite and sepiolite), layered double hidroxides and biopolymers (carboxymethylcellulose and zein) were evaluated as topical delivery systems with antibacterial activity and as oral delivery systems. For this study, neomycin, a topical antibiotic, indicated mainly for open wound infections. The drug amoxicillin, an antibiotic indicated mainly for throat infections, were also used in this study. Both antibiotics were used as model drugs. Initially, drugs were incorporated directly into the biopolymer matrix, comprising the combination of carboxymethylcellulos and zein, being conformed as movies and balls and evaluated for their antibacterial activity and controlled release simulating gastrointestinal fluids. Moreover, hybrids materials have been prepared where the neomycin drug was incorporated into the lamellar inorganic solids, such as montmorillonite by ion exchange reaction, and the fibrous type, such as sepiolite by adsorption in aqueous solution. But the drug amoxicillin was incorporated into layered double hydroxides by anion exchange and montmorillonite by cation exchange. The resulting hybrids were in turn combined with the biopolymer matrix yielding bionanocomposites shaped materials such as films were tested for their antibacterial activity, and the shaped materials beads were tested for their release in the gastrointestinal fluids. Through the analysis of various physico-chemical techniques, we observed the interactions between the studied materials, the formation of hybrids materials, obtaining the bionanocomposites materials and material efficiency when applied in controlled release of drugs both topical and use oral mainly influenced by the presence of zein, are promising as topical delivery systems and oral drugs.

Sequência didática com temas motivadores no ensino de física

This study is based on the design and development of a Didactic sequence in Physics for the first year of high school in a public school, involving structured activities on Astronomy topics, Astronautics and Aeronautics. In addition, it produced a didactic-pedagogic Tutorial for teachers to develop teaching-learning processes in Physics through activities with handmade rockets. These activities have been based on teaching moments of questioning, systematization and contextualization. In this context the understanding and the deepening of concepts and scientific and physical phenomena are related to everyday knowledge, in accordance with the historical-cultural theory, with the Three Pedagogic Moments, dialogicity and Information and Communication Technologies as instruments of triggering actions and motivation, like movies and applications in teaching Astronomy, Physics and Mathematics. The research activities were conduced by adopting a qualitative approach and included reports, questionnaires, semi-structured interviews and other notes. The development of the Didactic Sequence enabled a differentiated teaching and learning process, including aspects such as conceptualization, contextualization, flexibility, interdisciplinary and theoreticalexperimental relationship.

Increased Foreign Revenue Shares in the United States Film Industry: 2000 – 2014

The American film industry, which has historically been driven by the domestic market, now receives an increasing proportion of its revenue from abroad (foreign share). To determine the factors influencing this trend, this paper analyzed data from 11 countries of 2,337 American films released during 2000 – 2014. Both film and country attributes were analyzed to determine each attribute’s effect on foreign share, whether its effect size has changed over time and whether each attribute has changed in frequency amongst films released. The results identified six attributes, star actors, sequels, releases in top markets, release time lag, GDP growth and a match in language, that contributed to the increase in foreign share over this period.

BROMANCE : les paradoxes des stratégies homosociales.

Depuis les années 2000, l’apparition du terme Bromance marque la culture populaire américaine. Cette notion est apparue pour définir les amitiés entre hommes au cinéma, à la télévision et sur Internet. Les films de Bromance, caractérisés par une multitude de scènes de déclaration d’amour entre hommes, traduisent bien cette nouvelle façon d’aborder l’amitié au masculin. À travers les définitions de la masculinité dans ces films, l’enjeu de l’hétérosexualité demeure omniprésent. Malgré la fragilisation de certains stéréotypes traditionnels liés au masculin, il n’en demeure pas moins que la notion de «vraie» masculinité persiste et demeure systématiquement liée à l’hétérosexualité des hommes qui partagent cette amitié particulière qu’on appelle Bromance. Dans cette optique, plusieurs stratégies se manifestent pour prouver la masculinité et donc l’hétérosexualité des protagonistes, mais l’une d’entre elles semble être au cœur de ces films. Cette stratégie s’incarne sous la forme d’une compétition entre hommes qui mise sur la capacité à performer un acte conventionnellement associé à l’homosexualité. Sur Internet, des vidéos qui prennent le nom « Gay Chicken » présentent des hommes qui s’embrassent et qui se touchent sans être dérangés ou ébranlés. C’est la capacité à être calme et en contrôle en restant insensible au corps d’un autre homme qui démontrerait le côté inébranlable de son hétérosexualité et donc de sa masculinité. C’est cet esprit du « Gay Chicken » qui se retrouve un peu partout dans l’univers des films de Bromance. Paradoxalement, ces nouveaux «modèles» d’homme doivent pouvoir à la fois incarner une masculinité plus flexible, plus ouverte et sensible, mais doivent également prouver leur virilité. Cette « masculinité contemporaine » brouille les cartes entre ce qui est viril et ce qui ne l’est pas, entre ce qui est féminin et ce qui ne l’est pas et entre ce qui est homosexuel et ce qui ne l’est pas. Les relations homosociales dans le cadre de Bromances présentent alors des opportunités indispensables pour prouver à tous la force de son hétérosexualité. Ce travail de recherche se penchera donc plus précisément sur les paradoxes d’une « masculinité contemporaine » intimement liée à l’orientation hétérosexuelle, par l’entremise de certains films issus de la culture populaire américaine associée à la Bromance. L’objectif est de montrer comment ces films sont des manifestations significatives d’une nouvelle forme d’affirmation identitaire masculine qui passe par des relations homosociales où les tensions et sous-textes homosexuels se multiplient et doivent être réprimés ou invalidés continuellement.

Colonialism, political unconscious and cognitive mapping in the space of the film "Captain Phillips"

The purpose of this article has been made through a Marxist analysis of the US film "Captain Phillips" (PaulGreengrass, 2013), based on a true story. I have found how the evolution of capitalism in the West continuesto consolidate the belief reified in a historical and geographical superiority of the political and socioeconomicwestern models regarding Africa and Asia lowers models. At the same time, through categories like dialecticalmaterialism, criticism of diffusionist theory and application of cognitive mapping to large geopoliticalspaces located in most poor areas of the world, I have realized a remark about currently being articulatingthe political unconscious of working class in rich countries and the poor in poor countries, establishing arelationship between the ideological representation that takes an individual from his historical reality (ona scale that moves from local to global), and how he has developed a mental ability to escape of the responsibilityto make a critical review of what's happening around him in all areas. Finally, through physicalspace captured in the film, I have realized a materialist critique of globalized business process that takesplace through the carriage of goods, outlining spatial and cognitively limits of the mentality of our time, bothamong "winners"as among the "losers", based on the spatial movement of capital.

Is the cinematic newsreel the strongest weapon? The "Luce" newsreel reception during fascism

The Luce newsreel was a fascist-pivotal propaganda instrument. Mussolini thought movies were the strongestweapon; however, the efficiency of cinematographic propaganda on people did not work as well as expected,especially nonfiction. This article intends to value, through oral testimonies, the influence of Lucenewsreel on the Italian population during fascism, the degree of truth of film news, and which of those piecesof news were more repeated, as well as the influence of the Italian and its leader image on the collective mind.

Ludwing II of Baviera and Luchino Visconti: parallel lives? Study about Ludwing II of Baviera

This research presents Ludwig II of Baviera (1845-1886) as a historical figure and the vision of his reign theItalian director Luchino Visconti showed in his movies. This research states in an analytic and scrupulousway the relations between the historical figure, its filmic representation and the director himself. In addition,through an exhaustive research, this paper shows the aesthetics generated by directors like Visconti who reacheda remarkable peak in history of European film. Finally, this paper goes through the making of this film,which went from a transitional film within the Visconti oeuvre to one of his most troublesome and health-riskingprojects causing afterwards Visconti´s death.

El impacto de la crisis en la industria cinematográfica en Europa

Este trabajo analiza el impacto que ha generado la crisis económica y financiera más reciente en las industrias cinematográficas de siete países miembros de la Unión Europea. Las conclusiones señalan que, en efecto, la crisis ha impactado negativamente en las industrias de España e Italia, y muy gravemente en la de Portugal, pero en el lado contrario, la del Reino Unido ha experimentado un crecimiento apreciable y las de Francia y Alemania también lo han hecho, aunque en menor medida. Y en segundo lugar, es muy notable la escasa colaboración alcanzada entre los agentes europeos.

Travel, back and forth, to the myth. Cinema´s contribution to the formation of the tourist iconography of Mallorca

Mallorca, the largest of the Balearic Islands, is a well-known summer holidays destination; an ideal place to relax and enjoy the sun and the sea. That tourist gaze reflected on postcards results from advertising campaigns, where cinema played an important role with documentaries and fiction films. The origins of that iconography started in the decades of the 1920’s and 1930’s, reflecting the so-called myth of the “island of calm”. On the other hand, the films of the 1950’s and 1960’s created new stereotypes related to the mass tourism boom. Busy beaches and the white bodies of tourists replaced white sandy beaches, mountains and landscapes shown up in the movies of the early decades of the 20th century. Besides, hotels and nightclubs also replaced monuments, rural landscapes and folk exhibitions. These tourist images mirror the social and spatial transformations of Mallorca, under standardization processes like other seaside mass tourist destinations. The identity was rebuilt on the foundations of "modernity". Although "balearization" has not ceased, nowadays filmmaking about Mallorca is advertising again a stereotype close to that one of the 1920s and 1930s, glorifying the myth of the "island of calm". This singular identity makes the island more profitable for capital that searches socio-spatial differentiation in post-fordist times.

Receptive Vocabulary of CLIL and Non-CLIL Primary and Secondary School Learners

CLIL instruction has been reported to be beneficial for foreign language vocabulary learning since CLIL students show higher vocabulary profiles than students of their same age in traditional EFL contexts. However, to our knowledge, the receptive vocabulary knowledge of CLIL and non-CLIL learners at the end of primary and secondary education has not been examined yet. Hence, this study aims at comparing the receptive vocabulary size 79 CLIL primary learners with the receptive vocabulary knowledge of 331 non-CLIL learners at the end of primary and secondary school. Sex-based differences were also analysed. The 2k Vocabulary Levels Test (VLT) was used for the purposes of the study. Results revealed that learners’ receptive vocabulary sizes lie within the most frequent 1000 words, non-CLIL secondary school students throw better results than primary students but the differences between the secondary group and the CLIL group are not statistically significant. As for sex-based differences, we found no significant differences among the groups. These findings led us to believe that the CLIL approach offers a benefit for vocabulary acquisition since CLIL learners have been exposed to the foreign language for a shorter period of time and the results are quite similar to their non-CLIL secondary school partners.

La spiritualité dans le cinéma transnational. Une théologie pour le 21e siècle autour des philosophies du cinéma de Gilles Deleuze et de Stanley Cavell

Cette recherche part d’un double intérêt. Pour la spiritualité, dont on entend beaucoup parler dans un 21e siècle inquiet et en quête de nouveaux repères. Et pour le cinéma, ou 7e art, phénomène culturel phare des temps modernes, qui reflète abondamment les problématiques et questionnements du monde. À une époque où on observe une tendance à l’homogénéisation culturelle, résultat de la mondialisation économique, cette thèse traite du « cinéma transnational ». Elles aussi, les œuvres de ce cinéma traversent l’espace planétaire, mais tout en conservant un solide ancrage local et une singularité artistique. Ce sont en bonne partie les films que l’on retrouve dans les festivals internationaux, tels Cannes, Venise et Berlin. Le cinéma traduisant toutes les interrogations possibles du présent, plusieurs films apparaissent donc porteurs d’un questionnement à portée spirituelle. Et ce, avec des moyens non discursifs, propres à l’art cinématographique. Ils invitent aussi à la rencontre de l’autre. L’objectif de la thèse consiste à décrire comment, par l’analyse d’une douzaine de films transnationaux, on peut dégager de nouveaux concepts sur la façon avec laquelle se vit la spiritualité à notre époque, en relation avec l’autre, et pourquoi cette spiritualité s’accompagne nécessairement de considérations éthiques. Pour accomplir cette tâche, la thèse s’appuie sur les travaux de deux philosophes, Gilles Deleuze (France) et Stanley Cavell (États-Unis), qui ont marqué les études cinématographiques au cours des dernières décennies, par des approches jugées complémentaires pour cette recherche. Le premier a développé sa pensée à partir de ce qui distingue le cinéma des autres arts, et le second, à partir de l’importance du cinéma pour les spectateurs et les spectatrices. Enfin, la thèse se veut une théologie, ou pensée théologico-philosophique, indépendante d’une tradition religieuse et au diapason des réalités du 21e siècle.

Film som didaktisk resurs i religionsämnet : - Religionskunskapslärares syn på film i undervisningen

The purpose of this thesis is to examine how some Swedish teachers use film and movies as a resource when they teach religious studies in upper secondary school. Three questions were created to define the main focus of the thesis namely how the teachers perceived how they used film, how they justified there use and which advantages and disadvantages they see with using film in their teaching. To be able to answer them correctly the empirical data was collected by two methods; a survey and three interviews. The empirical data was then related to previous research in the same field. The thesis concludes that the teachers use film in the classroom in many ways, including as a way to present facts about religions to the students and as a way to make it easier to understand difficult parts of the subject. They also use film as way to make the students better at understanding and discussing different perspectives of religion and ethics. The main disadvantages film has is that it take a lot of time to show a film and use it in a meaningful way. The teachers also sometimes finds it hard to find a film that suits the purpose of showing it.

Les représentations queer au cinéma. L’abus sexuel au masculin et son incidence sur l’identifé et la sexualité des personnages de "La mauvaise éducation" (2004) de Pedro Almodovar et "Mysterious Skin" (2004) de Gregg Araki

Cette étude propose l’analyse de représentations queer dans le cinéma des années 2000. Plus précisément, elle porte sur la façon dont l’abus sexuel au masculin est représenté dans deux films produits en 2004, soit La mauvaise éducation (La mala educación), du réalisateur espagnol Pedro Almodovar, et Mysterious Skin, du réalisateur étatsunien Gregg Araki. À l’aide de la réflexion contenue dans Ça arrive aussi aux garçons : l’abus sexuel au masculin du sociologue Michel Dorais, l’objectif vise à démontrer comment cet événement traumatique influence de manière significative la construction identitaire et sexuelle des personnages principaux. De manière plus générale, ce mémoire positionne ces deux réalisateurs dans la grande et riche lignée du cinéma queer, qui met en scène des désirs hors norme et des identités sexuelles alternatives. Le premier chapitre porte sur les théories queer et ses diverses manifestations au grand écran. Il permet par la suite de réunir Almódovar et Araki dans une même étude et de souligner la pertinence de cette réunion. Le deuxième chapitre s’intéresse, à l’aide d’analyses d’extraits significatifs des films, à la façon dont chacun met en scène l’abus sexuel au masculin et comment cet événement se présente dans la vie des protagonistes. Le dernier chapitre se penche sur la construction identitaire et sexuelle des personnages principaux, afin de mieux comprendre l’incidence de l’abus sexuel. Jumelée aux travaux de Judith Butler, l’approche queer sera donc mise de l’avant dans cette étude qui se montre d’emblée attentive, d’un point de vue cinématographique, aux notions de sexe, de genre et de désir, et ce, à travers l’analyse de plusieurs extraits filmiques et d’éléments à la fois narratifs et structurels particulièrement significatifs quant à la représentation de l’abus sexuel au masculin.
