Designing a taxonomy for virtual museums for the use of AVICOM professionals

Caraceni, Simona January 2015 (has links)
This thesis aims to go beyond the concept of so called ‘virtual museums’. In this work I will attempt to trace a new definition of the term ‘virtual museum’ providing the concept with renewed dignity, comparable to ICOM’S definitions of museums and other existing definitions of the concept. To do so the main part of this thesis is about creating a meta-model of taxonomy capable of including all the experimentations that have taken place in the field of ‘virtual museums’ in the last 20 years. In this direction I have investigated the concept of the museum as a medium as described by McLuhan and other thinkers, both within and outside the field of museology. The discovery of an unabridged work by McLuhan on technology in museums endorses, and opens a discussion on how technology is intended to be used for the communication of heritage. Another aim of this thesis is to investigate how museum professionals can deal with the new role of Information Technology in communicating heritage. In this thesis I intend to respond to the need of museum professionals both inside and outside ICOM for definitions and clearer understanding concerning the following questions ‘What is a virtual museum? Can it be comparable with a ‘real’ museum? What different kinds of virtual museums can be discerned in past experimentations? Can they be included in a taxonomy? How does this change the day to day work of museum professionals in accordance with the new technological potential for the communication of heritage?

Technology-enhanced Classroom Environments and English Language Acquisition Among Native Spanish-speaking, English Language Learners in the Preschool and Elementary Classroom

Miller, Gary 08 1900 (has links)
This qualitative study addressed the question: What are the perceptions of preschool and elementary bilingual and ESL teachers on how technology-enhanced classroom environments support native Spanish-speaking English language learners in the acquisition of English as a second language? With the support of six school districts representing three different regions and 15 schools in Texas, this research investigated technology-enhanced learning environments and the influence of emerging technologies on language acquisition by focusing on classroom interactions and learner engagement in preschool and elementary settings. Forty-six teachers completed the self-identified online questionnaire and from that initial group of participants, 10 were chosen for the face-to-face semi-structured interviews. A two-cycle progressive refinement coding technique was used for the analysis of the teacher interviews. In Vivo coding was selected for the first-cycle coding methodology to study teacher perspectives using their direct language. For the second-cycle methodology, focus coding was chosen as a continuation of the analytical process examining the developing patterns resulting in the initial codes being grouped to form salient categories. This process of reanalyzing and reorganizing coded data led to the creation of four emergent themes and in the views of the teachers interviewed describes how emerging technologies influences English language acquisition. The four emergent themes identified were “engaging students for learning,” collaborating with others,” “developing and clarifying concepts,” and “creating authentic work.”

The use of mobile technologies for social media-based service delivery at Muni University Library, Uganda

Buruga, Bosco Apparatus January 2016 (has links)
This study aimed to understand how Muni University Library can effectively use mobile technologies to deliver social media-based library services. Data was collected from 100 undergraduate students and 4 members of staff of the University Library on the use of mobile and social media technologies for provision of library services and resources using self-administered questionnaires and face-to-face interviews, respectively. Only 88 student questionnaires were returned while all 4 members of staff participated in the face-to-face interviews. The results show that the majority (96.6 per cent) of the students own mobile devices and social media accounts that are used for both academic and personal purposes. There is convergence in responses among students and staff that mobile and social media technologies are crucial for provision of library services and resources in the 21st Century. They suggest that these technologies be used in the Muni University Library to access subject guides, MOPAC, mobile website, library map, and e-resources, and reference services. Also, the results show that the Muni University Library is already providing services to its users through mobile technologies and social media using WhatsApp, Facebook, and Kindle Fires e-readers. However, this study identified challenges that hinder the use of mobile and social media technologies, including unreliable internet connectivity, lack of a member of staff of the library responsible for managing technologies, lack of adequate skills among users and library staff required to use social media technologies, and lack of an independent library social media strategy. Discussion of the results and recommendations are presented in this mini-dissertation. / Mini Dissertation (MIT)--University of Pretoria, 2016. / Carnegie Corporation of New York / University of Pretoria / Muni University / Information Science / MIT / Unrestricted

Innovative use of Information Technology to Enhance Knowledge Management Practices at the Marist International University College, Nairobi - Kenya

Anduvare, Everlyn M. January 2016 (has links)
Information technologies have become relevant enablers in knowledge management (KM) initiatives in academic institutions. A previous study by Anduvare (2015) revealed that the Marist International University College, Nairobi - Kenya had not adequately adopted information technologies into KM practices entwined in teaching, learning and research. This research study, therefore, set out to explore technologies that are capable of supporting KM practices in academic institutions in order to recommend some to the MIUC. Purposive sampling was used to select the MIUC full-time academic staff members as the target population as the researcher believed that they actively use knowledge at the MIUC and hence, would be in a position to understand the extent of information technology usage in KM practices. The study employed a qualitative research design that involved the use of Google forms to conduct an online survey in order to collect data from the target population. The study achieved a 100% response rate. Content analysis was utilised to analyse the data during which data within the specified themes (collaborative and distributive learning; knowledge discovery; knowledge mapping and knowledge application) was scrutinised for meaning. The data was then interpreted, presented and discussed based on the research sub-questions set for the study. The findings of the study confirmed the existence of KM practices at the MIUC. The study, thus, recommended some information technologies that support the KM practices to the MIUC which had been established through a review of literature. / Mini Dissertation (MIT)--University of Pretoria, 2016. / Information Science / MIT / Unrestricted

Targeted killing: How and when intelligence agencies eliminate their targets and the impact of emerging technologies / Targeted killing: How and when intelligence agencies eliminate their targets and the impact of emerging technologies

Nguyen, Ba Nguyen January 2018 (has links)
History has shown that assassination could be wielded as an effective weapon in the pursuit of interest, security and power. As the feudal age neared its end in Europe, nation states emerged. Despite its pragmatic usefulness, assassination was considered unfit for this new form of governance. States no longer sought to destroy one another as predicted by Thomas Hobbes, but adhered to John Locke's proposed values, which believed that states could mutually exist as rivals. In this system which favored negotiation and settlements, it was difficult for assassination to have a place. Yet at the start of the 21st century, assassination once again saw employment. As of today, it is preferably referred to as targeted killing by its employers and has become somewhat of a 'new normal.' Clearly, there must be certain permissive catalysts that allowed this to happen. This master's thesis firstly explores the ways the United States, Israel and Russia conduct their assassination/targeted killing operations to present the unique ways these states eliminate their enemies, and secondly pinpoints the permissive causes that allowed these three super and great powers of assassination to transform the international norm against assassination and turn a dishonest, immoral practice into something more acceptable and fit...

No. of bitstreams: 1 Sandra Muniz Bozolan.pdf: 5735149 bytes, checksum: cde3d89f2f509e3937aadceed97ccea5 (MD5) Previous issue date: 2016-11-16 / This study presents a field study that uses Emerging Technologies, coupled with the Computational Thinking and can assist in the teaching and learning process. According to Valente (1998), the introduction of computers in education has obligatorily four equally important ingredients in the process of teaching and learning: computer, educational software, literate teacher able to use the computer as educational medium and the student. So, try to understand how the appropriation of technologies in the academic space, can enrich this fertile field of possibilities and resources, where the most common categories are: tutorials, exercises and practices, games and simulation that have a different mode. This field study investigated, monitored and analyzed the resources and methodologies used by the teacher during class. Effectively used the Processing software as a tool for teaching and learning and to develop the content of the subjects "Mathematics Fundamental Elements" in 2015 and "Introduction to Computational Thinking" in 2016 with the students of Communication Undergraduate Course Social - Medialogy, UNICAMP. The data extracted from this research through class monitoring and response questionnaires for the course students were compiled. These data were analyzed, categorized, compiled and submitted to analysis using the statistical method multidimensional through software CHIC – Coercion Implication and Hierarchic Classification - that generated the trees of similarity and the occurrence of numbers categories and from them, we used Excel, from which was generated trees similarity. Based on the data and analysis results, we identified some patterns that are responsible for this process of teaching and learning. They are divided into 7 phases: Emotional, Technical-Operational, Imitation, Relation-communication, Relation-information, Relation-reflexive expression and Self-formation. The understanding of the phases are fundamental elements to understand how the use of Emerging Technologies for teaching and learning were achieved in the two disciplines of the Midialogy course / O presente estudo apresenta um estudo de campo que utiliza as Tecnologias Emergentes, aliadas ao Pensamento Computacional e pode auxiliar no processo de Ensino e Aprendizagem. Segundo José Armando Valente (1998), a utilização de computadores para a Educação possui quatro ingredientes importantes que fazem parte do processo de ensino e aprendizagem: o computador, o software educativo, o professor alfabetizado e capacitado para utilizar os computadores no meio educacional e o aluno. Assim, tenta-se compreender como a apropriação das tecnologias no espaço acadêmico, pode enriquecer este campo fértil de possibilidades e recursos, onde as categorias mais comuns são: tutorias, exercícios e práticas, jogos e simulação que possuem a modalidade diversas. Este estudo de campo investigou, acompanhou e analisou os recursos e metodologias utilizadas pelos professores durante as aulas. Efetivamente, utilizou-se o software Processing como ferramenta para o ensino e aprendizagem e para desenvolver o conteúdo das disciplinas “Elementos Fundamentais de Matemática”, em 2015 e “Introdução ao Pensamento Computacional”, em 2016 com os alunos do Curso de Graduação em Comunicação Social – Midialogia, da UNICAMP. Os dados dos alunos utilizados para esta pesquisa foram compilados a partir de acompanhamento das aulas, respostas a questionários e relatórios realizados pelos alunos durante o curso. Esses dados foram categorizados, compilados e submetidos a análise, utilizando o método estatístico multidimensional que se baseia no software CHIC – Classificação Hierárquica, Implicativa e Coersitiva - que gerou as árvores de similaridade e os números de ocorrência das categorias. Com base nos dados e no resultado das análises, identificou-se alguns padrões que são responsáveis por este processo de ensino e aprendizagem. Eles são divididos em 7 fases: Emocional, Técnico-operacional, Imitação, Relação-comunicação, Relação-informação, Relação-expressão reflexiva e Autoformação. O entendimento das fases são elementos fundamentais para entender como o uso das Tecnologias Emergentes para o ensino e aprendizagem foram alcançados nas duas disciplinas do curso de Midialogia

Extração sequencial de compostos fenólicos e pectina da casca da manga assistida por ultrassom

Yamashita, Bruna Bárbara Valero Guandalini January 2017 (has links)
A manga é uma das frutas tropicais mais produzida no mundo, sendo amplamente consumida in natura e processada. O seu processamento gera grande quantidade de resíduos, sendo 15 % a 20 % do seu peso representado pela casca. A casca da manga contém quantidades significativas de fitoquímicos, como os compostos fenólicos, os carotenoides e a pectina. Devido à sua composição química, rica em compostos benéficos à saúde, e à grande quantidade de resíduos gerados anualmente a casca da manga apresenta enorme potencial para ser utilizada como ingrediente funcional. Dessa forma, o objetivo deste trabalho foi estudar a extração sequencial de compostos fenólicos e pectina da casca da manga com o auxílio do ultrassom. O trabalho foi divido em duas etapas. A primeira etapa avaliou a extração dos compostos fenólicos através de um planejamento experimental 32. As variáveis independentes foram a concentração de etanol na solução aquosa de extração (25-75 %, v/v) e a potência do ultrassom (25-75 %). Os resultados mostraram que o ultrassom não afetou significativamente a extração dos compostos fenólicos. Visando reduzir a quantidade de solvente e energia gastas no processo de extração, o melhor rendimento (67 %) foi obtido com solução aquosa com 50 % de etanol, sem aplicação do ultrassom, e 8 minutos de processamento. A segunda etapa do trabalho teve como objetivo estudar a influência do ultrassom e da extração prévia dos compostos fenólicos na qualidade e rendimento da pectina. Os resultados demostraram aumento superior a 50 % no rendimento da pectina com a aplicação do ultrassom no resíduo da extração dos compostos fenólicos. A extração prévia dos compostos fenólicos não prejudicou o rendimento e a qualidade da pectina extraída da casca da manga demostrando que os compostos fenólicos e pectina podem ser extraídos da casca da manga com auxílio de uma tecnologia emergente. / Mango is an important tropical fruit consumed in fresh or processed form worldwide. Commercial processing of mango into juice, nectar, pulp, puree, and jam produces 15-20 % peel waste. Mango peel contains significant amounts of phytochemicals, like phenolic compounds, carotenoids and pectin, which makes it suitable to be processed for value-added applications in functional foods and nutraceuticals. Mango peel has enormous potential as a functional ingredient. Thus the aim of this work was to study the ultrasound technology potential for sequential extraction of phenolic compounds and pectin from this agroindustrial waste. The work was divided in two steps. The first step was to explore the phenolic compound extraction assisted by ultrasound using an experimental design (32). The independent variables were ethanol concentration (%) and ultrasound power intensity (%). The results showed that the ultrasound power intensity did not affect the phenolic compound content extracted. Aiming to reduce the amount of solvent and the spending energy, the best extraction yield (67 %) was obtained using 50 % of ethanol concentration, without ultrasound intensity and 8 minutes of experiment under stirring. In the second step, the aim was to investigate the potential of ultrasound intensity and the influence polyphenols removal on the extracted pectin quality. Results showed that extraction yield enhance over than 50 % when ultrasound (75 %) was used on the phenolic extraction residue and the pectin obtained a galacturonic acid content higher than 65 %. The phenolic extraction did not affect the quality of the pectic polymer extracted from mango peel. The results showed that the phenolic compounds and pectin from mango peel can be extracted using an emerging technology.

Evaluation of using MIGFET devices in digital integrated circuit design / Avaliação do uso de dispositivos no projeto de circuitos integrados digitais

Baqueta, Jeferson José January 2017 (has links)
A diminuição das dimensões do transistor MOS tem sido a principal estratégia adotada para alcançar otimizações de desempenho na fabricação de circuitos integrados. Contudo, reduzir as dimensões dos transistores tem se tornado uma tarefa cada vez mais difícil de ser alcançada. Nesse contexto, vários esforços estão sendo feitos para encontrar dispositivos alternativos que permitam futuros avanços em relação à capacidade computacional. Entre as mais promissoras tecnologias emergentes estão os transistores de efeito de campo com múltiplos e independentes gates (MIGFETs). MIGFETs são dispositivos controlados por mais que um terminal de controle permitindo que funções Booleanas com mais de uma variável sejam implementadas por um único dispositivo. Redes de chaves construídas com dispositivos MIGFET tendem a ser mais compactas do que as redes de chaves tradicionais. No entanto existe um compromisso em relação a redução no número de chaves, devido à maior capacidade lógica, e um maior tamanho e pior desempenho do dispositivo. Neste trabalho, pretendemos explorar tal balanceamento no sentido de avaliar os impactos do uso de MIGFETs na construção de circuitos integrados digitais. Dessa forma, alguns critérios de avaliação são apresentados no sentido de analisar área e atraso de circuitos construídos a partir de dispositivos MIGFET, onde cada transistor é representado por um modelo RC. Em particular, tal avaliação de área e desempenho é aplicada no projeto de circuitos somadores binários específicos (metodologia full-custom). Além do mais, bibliotecas de células construídas a partir de dispositivos MIGFET são utilizadas na síntese automática de circuitos de referência através da metodologia standard-cell. Através dos experimentos, é possível ter-se uma ideia, mesmo que inicial e pessimista, do quanto o layout de um dado MIGFET pode ser maior do que um single-gate FinFET e ainda apresentar redução na área do circuito devido à compactação lógica. / The scaling of MOS transistor has been the main manufacturing strategy for improving integrated circuit (IC) performance. However, as the device dimensions shrink, the scaling becomes harder to be achieved. In this context, much effort has been done in order to develop alternative devices that may allow further progress in computation capability. Among the promising emerging technologies is the multiple independent-gate field effect transistors (MIGFETs). MIGFETs are switch-based devices, which allow more logic capability in a single device. In general, switch networks built through MIGFET devices tend to be more compact than the traditional switch networks. However, there is a tradeoff between the number of logic switches merged and the area and performance of a given MIGFET. Thus, we aim to explore such a tradeoff in order to evaluate the MIGFET impacts in the building digital integrated circuits. To achieve this goal, in this work, we present an area and performance evaluation based on digital circuit built using MIGFET devices, where each MIGFET is represented through RC modelling. In particular, such an evaluation is applied on full-custom design of binary adder circuits and on standard-cell design flow targeting in a set of benchmark circuits. Through the experiments, it is possible have an insight, even superficial and pessimist, about how big can be the layout of a given MIGFET than the single-gate FinFET and still show a reduction in the final circuit area due to the logic compaction.
