Made available in DSpace on 2016-04-29T14:23:22Z (GMT). No. of bitstreams: 1 Jose Antonio Fonteles Cruz Junior.pdf: 3570381 bytes, checksum: 0714cae52f28c48498fbd5da21b5c0a4 (MD5) Previous issue date: 2013-09-25 / With the expansion of the new technologies, routines and social spheres are affected. The society always develop technologies that served of tool for the realisation of tasks, of the more Simple to the most complex. All the technologies developed until then brought like consequence impacts in the walk of this society and with the new technologies It is not being different. However, the leverage and changes that these devices impose on the contemporary society possess singular characteristics and, besides that, His field of impact is gigantic owed his countless applicabilities in the social spheres. The aim of this work, in the first moment, is to understand this contemporary stage splitting of the theoretical analyses of Castells, Levy, Santaella, Read and Recuero. After understood this current society, split for the theoretical analysis of the impacts of these new technologies in the field of the education. For this, Moran and Machado will be the main theorists. At last, after visualising, of theoretical and practical form, through investigations of institutes and newspapers recognised, arrive to the big aim that is to analyse of practical form, but with knowledge theoretical, like the IESAM (instituito Of upper education of the Amazônia), through the Moodle, if use of a new technology for pedagogical ends and communicational for the upper education / Com o advento das novas tecnologias, rotinas e esferas sociais são afetadas. A sociedade sempre buscou desenvolver tecnologias que servissem de ferramenta para a realização de tarefas, das mais simples às mais complexas. Todas as tecnologias desenvolvidas até então trouxeram como consequência impactos no caminhar dessa sociedade e com as novas tecnologias não está sendo diferente. Entretanto, as influencias e mudanças que estes aparatos impõem sobre a sociedade contemporânea possuem características singulares e, além disso, seu campo de impacto é gigantesco devido as suas inúmeras aplicabilidades nas esferas sociais. O objetivo deste trabalho, no primeiro momento, é entender este cenário contemporâneo partindo das análises teóricas de Castells, Levy, Santaella, Lemos e Recuero. Após entendida esta sociedade atual, partimos para a análise teórica dos impactos destas novas tecnologias no campo da educação. Para isso, Moran e Machado serão os principais teóricos. Por fim, após visualizar, de forma teórica e prática, através de pesquisas de institutos e periódicos reconhecidos, chegamos ao grande objetivo que é analisar de forma prática, mas com embasamento teórico, como o IESAM (instituito de ensino superior da Amazônia), através do Moodle, se apropia de uma nova tecnologia para fins pedagógicos e comunicacionais para o ensino superior

Filmspridning och ny teknik i samband med huliganvåld : <em>En studie om hur filmklipp sprids och hur dagens teknik används av svenskafotbollshuliganer och supportrar</em> / Film distribution and new technologies in the context of hooligan violence : <em>A study on how video clips are spread and how today's technology is used by swedish football hooligans and supporters</em>

Hozali, Jafar, Uddin, Shafi January 2009 (has links)
<p>We have in this study preformed a quantitative examination on how hooligans use film and new technologies to spread private videos on the Internet. With today´s technologies it is very easy for hooligans to publish their videos. In this study, we have choosen to do a questionnaire poll based on seven questions about what people think of hooliganviolence on online video sharing sites. We have also conducted an online interview with a former swedish hooligan. The people who participated in our study are all anonymous, and therefore we have no age or gender included in our study. Most of the videos discussed here are used as entertainment, according to their publishers/viewers, but also as a method of advertising the supporterclubs of different teams. Following our study we can conclude that new technologies have a huge importance for the spread of these videos.</p>

The Blue Glow From the Back Row: The Impact of New Technologies on the Adolescent Experience of Live Theatre

Richardson, John M. 12 October 2010 (has links)
This article considers the impact of new technologies on the adolescent experience of live, literary theatre. Drawing together the work of theorists in literacies, new technologies and audience studies, together with brain research, and the results of a focus group of four secondary students who have seen four plays at Canada’s National Arts Centre, it examines the consequences of young people’s immersion in digital culture and the new mindset that often results. The expectation of instant access to data, inter-connectivity, stimulation and control can make it difficult for adolescents to decode the metaphorical aspects of a theatrical performance. The article concludes that language arts and dramatic arts educators have a key role in teaching students how to decode—and therefore enjoy and appreciate— a play.

Integration of New Technologies into Existing Mature Process to Improve Efficiency and Reduce Energy Consumption

Ahmed, Sajjad 17 June 2009 (has links)
Optimal operation of plants is becoming more important due to increasing competition and small and changing profit margins for many products. One major reason has been the realization by industry that potentially large savings can be achieved by improving processes. Growth rates and profitability are much lower now, and international competition has increased greatly. The industry is faced with a need to manufacture quality products, while minimizing production costs and complying with a variety of safety and environmental regulations. As industry is confronted with the challenge of moving toward a clearer and more sustainable path of production, new technologies are needed to achieve industrial requirements. In this research, a new methodology is proposed to integrate so-called new technologies into existing processes. Research shows that the new technologies must be carefully selected and adopted to match the complex requirements of an existing process. The new proposed methodology is based on four major steps. If the improvement in the process is not sufficient to meet business needs, new technologies can be considered. Application of a new technology is always perceived as a potential threat; therefore, financial risk assessment and reliability risk analysis help alleviate risk of investment. An industrial case study from the literature was selected to implement and validate the new methodology. The case study is a planning problem to plan the layout or design of a fleet of generating stations owned and operated by the electric utility company, Ontario Power Generation (OPG). The impact of new technology integration on the performance of a power grid consisting of a variety of power generation plants was evaluated. The reduction in carbon emissions is projected to be accomplished through a combination of fuel switching, fuel balancing and switching to new technologies: carbon capture and sequestration. The fuel-balancing technique is used to decrease carbon emissions by adjusting the operation of the fleet of existing electricity-generating stations; the technique of fuel-switching involves switching from carbon-intensive fuels to less carbon-intensive fuels, for instance, switching from coal to natural gas; carbon capture and sequestration are applied to meet carbon emission reduction requirements. Existing power plants with existing technologies consist of fossil fuel stations, nuclear stations, hydroelectric stations, wind power stations, pulverized coal stations and a natural gas combined cycle, while hypothesized power plants with new technologies include solar stations, wind power stations, pulverized coal stations, a natural gas combined cycle and an integrated gasification combined cycle with and without capture and sequestration. The proposed methodology includes financial risk management in the framework of a two stage stochastic programme for energy planning under uncertainty: demands and fuel price. A deterministic mixed integer linear programming formulation is extended to a two-stage stochastic programming model in order to take into account random parameters, which have discrete and finite probabilistic distributions. Thus, the expected value of the total costs of power generation is minimized, while the objective of carbon emission reduction is achieved. Furthermore, conditional value at risk (CVaR), a most preferable risk measure in the financial risk management, is incorporated within the framework of two-stage mixed integer programming. The mathematical formulation, which is called mean-risk model, is applied for the purpose of minimizing expected value. The process is formulated as a mixed integer linear programming model, implemented in GAMS (General Algebraic Modeling System) and solved using the CPLEX algorithm, a commercial solver embedded in GAMS. The computational results demonstrate the effectiveness of the proposed new methodology. The optimization model is applied to an existing Ontario Power Generation (OPG) fleet. Four planning scenarios are considered: a base load demand, a 1.0% growth rate in demand, a 5.0% growth rate in demand, a 10% growth rate in demand and a 20% growth rate in demand. A sensitivity analysis study is accomplished in order to investigate the effect of parameter uncertainties, such as uncertain factors on coal price and natural gas price. The optimization results demonstrate how to achieve the carbon emission mitigation goal with and without new technologies, while minimizing costs affects the configuration of the OPG fleet in terms of generation mix, capacity mix and optimal configuration. The selected new technologies are assessed in order to determine the risks of investment. Electricity costs with new technologies are lower than with the existing technologies. 60% CO2 reduction can be achieved at 20% growth in base load demand with new technologies. The total cost of electricity increases as we increase CO2 reduction or increase electricity demand. However, there is no significant change in CO2 reduction cost when CO2 reduction increases with new technologies. Total cost of electricity increases when fuel price increases. The total cost of electricity increases with financial risk management in order to lower the risk. Therefore, more electricity is produced for the industry to be on the safe side.

Bottom-up technology transmission within families : how children influence their parents in the adoption and use of digital media

Correa, Teresa 11 November 2013 (has links)
This dissertation investigated the bottom-up technology transmission process in a country with varied levels of technology diffusion, such as Chile. In particular, I explored how children act as technology brokers within their families by influencing their parents' adoption of and learning about digital media, so as to include older generations in the digital environment. In order to do this, I measured to what extent this process occurs, I proposed a typology of factors that intervene in the process and analyzed the outcomes variables related to the phenomenon. Methodologically, I used a mixed-methods research approach by combining in-depth interviews with a self-administered paper-and-pencil survey taken by dyads of one parent and one child. I analyzed 28 interviews involving one 12 to 18-year-old child and one parent or legal guardian (14 dyads) stratified by socioeconomic background, age, and gender. In addition, I conducted the parent-child survey among school-aged children and their parents in three schools, stratified by socioeconomic status. One class per cohort from 7th to 11th grades was randomly surveyed. In total, 381 students and 251 parents completed the surveys. The analyses showed that bottom-up technology transmission occurs at some degree for all the technologies investigated in this study. However, children's influence should not be overstated because they play only one part among a number of factors involved in the digital inclusion of older generations. It also established a typology of factors related to the process at different levels, including structural influences, family structure, strategies employed by youth, and psychological dispositions of parents. Specifically, the analyses consistently found that this process was more likely to occur among people from a lower socioeconomic status. Also, the transmission was associated with more fluid parent-child interactions and occurred among parents who perceived the technology to be useful. Regarding the outcome variables, it demonstrated that this phenomenon is linked, although weakly, to greater levels of perceived competence among parents and higher esteem among young people. Finally, it suggested that bottom-up technology transmission is associated with the reduction of some socioeconomic gaps in digital media use. / text

Le droit de l'OHADA face au commerce électronique

Sanni Yaya, Mouhamadou 07 1900 (has links)
Le droit de l’OHADA face au commerce électronique est une réflexion épistémologique sur les questions juridiques que posent les transactions électroniques au sein des pays de l’Organisation pour l’Harmonisation en Afrique du Droit des Affaires (OHADA). Plus précisément, cette réflexion est une prospective sur l’encadrement juridique du commerce électronique par l’OHADA à partir des expériences menées notamment en Amérique du Nord (Canada-Québec) et en Europe. Les nouvelles technologies de l’information posent en Afrique comme elles l’ont fait ailleurs des défis au droit. Plusieurs initiatives régionales et nationales ont vu le jour au cours des dernières années pour relever ces défis. Seulement, le caractère hétérogène des législations mises en place est à même d’altérer la sécurité juridique régionale tant recherchée par l’organisation. Prenant appui sur la théorie de la circulation des modèles juridiques, cette thèse propose une véritable harmonisation dans le cadre de l’OHADA. Harmonisation qui veillera à prendre en compte les « spécificités africaines » tout en faisant de la Cour commune de Justice et d’Arbitrage (CCJA) d’Abidjan la plus haute juridiction communautaire en matière de commerce électronique. / Le droit de l’OHADA face au commerce électronique (OHADA law pertaining to e-commerce) is an epistemological reflection on the legal issues raised by e-trade conducted among members of the Organisation for the Harmonisation of Business Law in Africa (OHADA). This forward looking analysis of the organization’s legal framework governing e commerce draws upon relevant experiments carried out notably in North America (Canada-Québec) and Europe. In Africa, as elsewhere, the new information technologies pose certain legal challenges. During the past several years, various regional and national initiatives have addressed these challenges. However, the heterogeneous nature of the different laws implemented impairs the regional-level legal security sought by OHADA. Building on legal transplant, this dissertation proposes, within the context of OHADA, a true harmonization that will ensure that “African specificities” are taken into account while making the Common Court of Justice and Arbitration (CCJA) in Abidjan the highest community jurisdiction in matters of e-commerce.
