The purpose of this mixed methods study was to explore middle school teachers’ pedagogy and their transformations as they implement one-to-one laptop instructional technology in their classroom environments. Statistical correlation and narratives provided a greater understanding of the research problem. A mixed methods approach was the most appropriate research design for this study due to the nature of information being collected. Data collection draws from several sources, such as questionnaires, interviews, or analysis of documents. In this study, the researcher used the questionnaire responses from 48 teachers and transcripts of semi structured focus group interviews of four teachers to create a framework of how middle school teachers perceive their self-efficacy in using one-to-one laptop instructional technology, their preparedness within Professional Learning Communities (PLCs) to implement instructional technology, and how their pedagogical practices may have changed.

Cette recherche porte sur des modélisation des évolutions à long terme du trait de côtes, dans laquelle on propose un modèle qui combine à la fois une contribution des processus cross-shore et celle de processus longshore pour améliorer les capacités prédictives. Le modèle cross-shore de Splinter et al. (2014) est ré-implémenté dans un but de comparaison avec le modèle combiné. Nous présentons un modèle longshore simple basé sur une approche "one-line" moyenne dans le temps. L’analyse de ce modèle longshore donne l’orientation de la plage d’équilibre par rapport à l’orientation de l’onde incidente. Il révèle également qu’une partie de la variabilité saisonnière des positions du trait de côte est due au transport par la dérive littorale. Par conséquent, la contribution longshore du modèle combiné améliore les capacités prédictives. Les prédictions du modèle sont confrontées à des mesures des positions du trait de côte de différents types de plages, comme celles de Truc Vert, en France et des plages en baie avec courbure de Narrabeen, en Australie et de Nha Trang, au Vietnam.Cette thèse offre deux nouvelles contributions précieuses. Le premier est un modèle longshore simple et l’orientation de la plage d’équilibre. Le second est un modèle combiné de long-shore et cross-shore. / This research focuses on the long-term shoreline evolution modeling, in which a combined model comprising the shoreline change due to longshore drift in a cross-shore shoreline model is proposed to improve the predictive skills of the long-term shoreline response. The cross-shore shoreline model of cite{splinter2014} is re-implemented for a purpose of comprehensive comparison with the combined model. A simplified longshore shoreline model is developed on the basis of the one-line type approach. The analysis of this longshore model yields the equilibrium beach orientation in relation to the incident wave orientation. It also reveals that part of seasonal shoreline position variability is due to the longshore transport. Therefore, the presence of the longshore model in the combined model clearly improves the model skills. The shoreline evolution models are calibrated with data from different beach types, such as a straight open beach shoreline of Truc Vert, France and embayed beach shoreline of Narrabeen, Australia and Nha Trang, Vietnam.This thesis gives two valuable contributions. The first one is a simplified longshore model and the equilibrium beach orientation. The second one is a combined longshore cross-shore phenomenological model.

The purpose of this qualitative study was to apply the lessons learned from the Apple Classrooms of Tomorrow studies, the SAMR model, and Diffusion of Innovations theory to explore stakeholder perceptions of iPad integration at an urban high school in Massachusetts. The implementation was viewed through the lenses of the Apple Classrooms of Tomorrow (ACOT) studies (Baker, Gearhart, & Herman, 1990; Dwyer, Ringstaff, & Haymore Sandholtz, 1990a; Dwyer, Ringstaff, & Haymore Sandholtz, 1990b), Rogers’ (2003) Diffusion of Innovation (DOI) Model, and Puentedura’s (2012) Substitution, Augmentation, Modification, and Redefinition (SAMR) Model. The researcher used qualitative analysis to code the data. Through data analysis, five themes emerged: communication, control, division, distraction, and workflow. The iPads changed how and when students and teachers communicated. Teachers sought more control over the iPads in the classroom. Control over learning shifted toward the students with the introduction of the iPads. Divisions became apparent with iPad use: new teachers versus veteran teachers and upperclassman versus underclassman. Distractions were rampant. The iPads influenced the workflow of how teachers taught and how students accessed the curriculum.

Debora Maria Rossi de Medeiros / Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Ciência da Computação, 2016. / O crescente aumento da exploração do meio ambiente e da biodiversidade faz com que seja necessário preservar os recursos naturais para evitar escassez e reduzir os impactos ambientais. Utilizando dados de distribuição geográfica de espécies combinados com características ambientais e, é possível gerar modelos de distribuição geográfica de espécies. Esses modelos podem ser aplicados na solução de diversos problemas relacionados à manutenção da biodiversidade e preservação das espécies, por exemplo, como auxiliar na dentição de politicas publica e cenários para o uso sustentável do meio ambiente, estudar o potencial de crescimento e proliferação de espécies invasoras, e avaliar os impactos das mudanças climáticas na biodiversidade. Este trabalho propõe um método para a geração de modelos de distribuição de espécies através da aplicação de conceitos de aprendizado de maquina adaptados para a resolução de problemas de uma classe. Os modelos gerados possibilitam a localização de áreas com características similares ao habitat natural das espécies e, dessa forma, contribuem para a sua preservação. Para avaliar a sua acácia, o método proposto foi aplicado em uma base de dados real e algumas bases de Benchmark, e comparado com uma versão do algoritmo Suporta Vector Machies, para dados com uma única classe. O SVM é um dos algoritmos mais aplicados na modelagem de distribuição de espécies e esta disponível em algumas das soluções mais utilizados pelos pesquisadores da área, como o Openmodeller 1 e o Biodiversityr2, avaliação para outras situações, como bases de dados que incluam dados de ausência de espécies bases de dados com um maior numeram de exemplos, os resultados são promissores e indicam que o aprofundamento da pesquisa nessa área pode ter impacto relevante para a modelagem de distribuição de espécies, portanto oferece uma base solida para avaliação. Os resultados mostraram que o método proposto é vi Avel e competitivo. Em muitos casos, como para dados possíveis de serem separados linearmente, o novo método apresentou resultados superiores aos do SVM. Embora ainda seja necessário estender a sua avaliação para outras situações, como bases de dados que incluam dados de ausência de espécies e bases de dados com um maior numeram de exemplos, os resultados são promissores e indicam que o aprofundamento da pesquisa nessa área pode ter impacto relevante para a modelagem de distribuição de espécies. / The increasing exploitation of the environment and biodiversity makes it necessary to preserve the natural resources to avoid scarcity and reduce environmental impacts. Using geographical species distribution data combined with environmental and ecological characteristics, geographical species distribution models can be generated. These models can be applied in solving various problems related to the maintenance of biodiversity and species conservation, such as an aid in the denition of public policies and scenarios for sustainable use of the environment, study the potential for growth and proliferation of invasive species, and assess the impacts of climate change on biodiversity. This work proposes a method for generating geographical species distribution models by applying Machine Learning concepts adapted to solving one-class problems. The generated models enable the identication of areas with similar characteristics to the natural habitat of the species and therefore contribute to its preservation. To evaluate its eectiveness, the proposed method was applied to a real database and some benchmark bases, and compared with a version of the Support Vector Machines algorithm, for one-class classication . The SVM is one of the most applied algorithms for species distribution modelling and is available in some of the solutions most used by researchers in this eld, such as openModeller 3 and BiodiversityR 4. Therefore, it provides a solid base for evaluation. The results showed that the proposed method is viable and competitive. In many cases, such as when the data can be linearly separable, the results obtained by applying the new method were better than those of SVM. Although additional research is necessary to evaluate the method in dierent situations, such as by using databases that include species absence data and databases with a large number of examples, the results are promising and indicate that further research in this area could have a relevant impact to the species distribution modelling technique.

The contemporary poetry feels free of the classical rules; theater no longer obeys the requirements of the poetic "manuals"; the rigid boundaries between genres disappears; artists cease to represent to the public to talk with him. In the last decades of twentieth century and in the twenty-first century, emerges the laughable phenomenon of One-man Show in the brazilian scene, object of this research, as a result of this evolution of the performing arts. It is a form of theater that emerged in the brazilian context, snatching public attention in alternative spaces, theaters and, as it should be, also on the Internet, often confused with the Stand-up Comedy. It is necessary a research that delimitate and pursue to identify the essential characteristics of the brazilian One- Man Show, not only by the absence of theoretical references concerning this, but also to understand some aspects of the brazilian scene and the situation of laughter and comedy in it. In the first chapter, a discussion about comedy and laughter in classical antiquity is presented, using the writings of Plato and Aristotle as a starting point; in the second, some of the main classical theories of laughter are reviewed, attempting to identify the general characteristics that enable to understand the construction of the comedy; the third chapter generally dicusses about the moment of the brazilian theatrical scene in which emerges the One-man Show; and in the fourth chapter, there is an explanation about this phenomenon and a description of the practical exercise titled Experimento One-person Show: Damas / Desde a d?cada de 1970, o mundo observa a fragmenta??o, o hibridismo, a pluralidade e a miscigena??o que v?m tomando conta das artes da cena. A poesia contempor?nea sente-se livre das regras cl?ssicas; o teatro j? n?o mais obedece ?s prescri??es dos manuais po?ticos; desaparecem as fronteiras r?gidas entre os g?neros; os artistas deixam de representar para o p?blico para dialogar com ele. Como consequ?ncia dessa evolu??o das artes c?nicas, emerge nas ?ltimas d?cadas do s?culo XX e in?cio do s?culo XXI na cena brasileira o fen?meno derris?vel objeto de estudo dessa pesquisa, o One-man Show. Trata-se de um formato teatral que despontou no cen?rio brasileiro arrebatando a aten??o do p?blico em espa?os alternativos, teatros e, como n?o poderia deixar de ser, tamb?m na internet, sendo muitas vezes confundido com o Stand-up Comedy. Uma pesquisa que delimite e busque identificar as caracter?sticas fundamentais do One-man Show brasileiro, fazse necess?ria n?o somente pela aus?ncia de estudos sobre o referido assunto, mas tamb?m para se compreender alguns aspectos da cena brasileira e da situa??o do riso e do c?mico dentro dela. No primeiro cap?tulo, apresenta-se uma discuss?o sobre a com?dia e o riso na Antiguidade cl?ssica, tomando os escritos de Plat?o e Arist?teles como ponto de partida; no segundo, s?o analisadas algumas das principais teorias cl?ssicas do riso procurando identificar caracter?sticas gerais que permitam entender tamb?m a constru??o da comicidade; no terceiro, aborda-se de um modo geral o momento da cena teatral brasileira em que emerge o One-man Show e, no quarto cap?tulo, h? a explana??o acerca de tal fen?meno e a descri??o do exerc?cio pr?tico intitulado Experimento One-person Show: Damas

O mangá é uma das mídias mais relevantes do Japão. Ele figura parte significativa da cultura popular japonesa e, como produto de tal cultura, está intrinsecamente ligado aos aspectos que constituem a sociedade nipônica. Com sua linguagem híbrida (imagem e escrita), o mangá vem permeado de elementos socioculturais, cujas representações apresentam um mosaico da sociedade. Como uma imagem substituta, ele retrata práticas sociais e conceitos (valores) que permitem diferentes e várias leituras da sociedade e cultura japonesa. Nessas narrativas, o protagonista do mangá agirá como ator social, sendo, concomitantemente, produtor e testemunha das práticas socioculturais japonesas. Este trabalho tem como objeto de estudo o mangá One Piece de Oda Eiichiro (1975), cujo enredo narra as aventuras da tripulação Piratas do Chapéu de Palha, comandada por Monkey D. Luffy. Por meio do protagonista e herói da narrativa, Monkey D. Luffy, procurou-se identificar elementos que fazem referência a aspectos característicos da figura do herói, visto que esse se reveste com as características de maior valor e destaque de sua cultura de origem. Na análise constatou-se a representação e o praticar de valores como honra, autossacrifício, lealdade, esforço, disciplina, perseverança e sinceridade. Pelas interações do protagonista também pode se verificar a pratica de dinâmicas sociais como hierarquia social, o conceito de on (débito moral) e giri (dever moral), além de referências a aspectos culturais da yakuza (máfia japonesa). / Manga is one of the most relevant midia in Japan. It has a significant part of Japanese popular culture and, as a product of such culture, is intrinsically linked to aspects that constitute Japanese society. With its hybrid language (image and writing), manga is permeated by sociocultural elements, whose representations present a mosaic of society. As a surrogate image, manga depicts social practices and concepts (values) that allow different and various readings of Japanese society and culture. In these narratives, the protagonist of manga will behave as a social actor, being, at the same time, a producer and a witness of Japanese sociocultural practices. Therefore, the aim of this study is manga One Piece written by Oda Eiichiro (1975), whose story tells the adventures of Hat of Straws pirate crew, commanded by Monkey D. Luffy. Through the protagonist and hero of the narrative, Monkey D. Luffy, it was expected to identify elements that make reference to characteristic aspects of the hero, since this one is full of characteristics of greater value and highlight of his culture of origin. In the analysis, it was found the representation and practice of values like honor, self-sacrifice, loyalty, effort, discipline, perseverance and sincerity. Through the interactions of the protagonist can also be verified the practice of social dynamics such as social hierarchy, the concept of on (moral debt) and giri (moral duty), as well as references to cultural aspects of yakuza (Japanese mafia).

Announced in 2013, the One Belt One Road(OBOR) Initiative is considered the most important geopolitical development strategy of the 21st-century in the country. The Chinese government aims to promote trade and investment with more than 63 OBOR countries. In this paper, I analyze the impact of One Belt One Road Initiative on China’s foreign direct investment for a period of 2003-2015 with a country level panel data. Other determinants frequently used in the FDI literature such as market size, geographical distance, resources, trading effects and political risks are also considered in the model. The empirical results show that OBOR policy is positively associated with China’s outward FDI flow. I believe the research result indicates a policy related trend for Chinese firms’ overseas investments.

The purpose of this paper is to investigate the advantages and disadvantages of the method of one-click purchasing. One-click purchasing is a method allowing the customers to transact a purchase with only one click. The customer has entered the payment information necessary to complete the purchase at a previous occasion. Within the next buying opportunity, the customer can purchase products with one single click. The analysis and conclusions is based on both primary and secondary sources. The primary sources represent the result of a questionnaire performed with 200 respondents. The survey showed that the most common advantages with the method was fast, smooth, easy and time efficient. The disadvantages on the other hand were more varying and included cons such as uncertain, unreliable, risk-taking, page hacking, fraud and identity hijacking. The conclusion is therefore that the disadvantages are in grater number and also more shifting, which means that the perception of the one-click purchasing method tends to be more negative.
