Enhancing Physics Education in the National Defence University : A design based research approach in the production of learning material

This research is connected with an education development project for the four-year-long officer education program at the National Defence University. In this curriculum physics was studied in two alternative course plans namely scientific and general. Observations connected to the later one e.g. student feedback and learning outcome gave indications that action was needed to support the course. The reform work was focused on the production of aligned course related instructional material. The learning material project produced a customized textbook set for the students of the general basic physics course. The research adapts phases that are typical in Design Based Research (DBR). The research analyses the feature requirements for physics textbook aimed at a specific sector and frames supporting instructional material development, and summarizes the experiences gained in the learning material project when the selected frames have been applied. The quality of instructional material is an essential part of qualified teaching. The goal of instructional material customization is to increase the product's customer centric nature and to enhance its function as a support media for the learning process. Textbooks are still one of the core elements in physics teaching. The idea of a textbook will remain but the form and appearance may change according to the prevailing technology. The work deals with substance connected frames (demands of a physics textbook according to the PER-viewpoint, quality thinking in educational material development), frames of university pedagogy and instructional material production processes. A wide knowledge and understanding of different frames are useful in development work, if they are to be utilized to aid inspiration without limiting new reasoning and new kinds of models. Applying customization even in the frame utilization supports creative and situation aware design and diminishes the gap between theory and practice. Generally, physics teachers produce their own supplementary instructional material. Even though customization thinking is not unknown the threshold to produce an entire textbook might be high. Even though the observations here are from the general physics course at the NDU, the research gives tools also for development in other discipline related educational contexts. This research is an example of an instructional material development work together the questions it uncovers, and presents thoughts when textbook customization is rewarding. At the same time, the research aims to further creative customization thinking in instruction and development.

Framework for enabling highly available distributed applications for utility computing

The move towards IT outsourcing is the first step towards an environment where compute infrastructure is treated as a service. In utility computing this IT service has to honor Service Level Agreements (SLA) in order to meet the desired Quality of Service (QoS) guarantees. Such an environment requires reliable services in order to maximize the utilization of the resources and to decrease the Total Cost of Ownership (TCO). Such reliability cannot come at the cost of resource duplication, since it increases the TCO of the data center and hence the cost per compute unit. We, in this paper, look into aspects of projecting impact of hardware failures on the SLAs and techniques required to take proactive recovery steps in case of a predicted failure. By maintaining health vectors of all hardware and system resources, we predict the failure probability of resources based on observed hardware errors/failure events, at runtime. This inturn influences an availability aware middleware to take proactive action (even before the application is affected in case the system and the application have low recoverability). The proposed framework has been prototyped on a system running HP-UX. Our offline analysis of the prediction system on hardware error logs indicate no more than 10% false positives. This work to the best of our knowledge is the first of its kind to perform an end-to-end analysis of the impact of a hardware fault on application SLAs, in a live system.

Operationalizing Supply Chain vs. Supply Chain Competion

Competition is an immensely important area of study in economic theory, business and strategy. It is known to be vital in meeting consumers’ growing expectations, stimulating increase in the size of the market, pushing innovation, reducing cost and consequently generating better value for end users, among other things. Having said that, it is important to recognize that supply chains, as we know it, has changed the way companies deal with each other both in confrontational or conciliatory terms. As such, with the rise of global markets and outsourcing destinations, increased technological development in transportation, communication and telecommunications has meant that geographical barriers of distance with regards to competition are a thing of the past in an increasingly flat world. Even though the dominant articulation of competition within management and business literature rests mostly within economic competition theory, this thesis draws attention to the implicit shift in the recognition of other forms of competition in today’s business environment, especially those involving supply chain structures. Thus, there is popular agreement within a broad business arena that competition between companies is set to take place along their supply chains. Hence, management’s attention has been focused on how supply chains could become more aggressive making each firm in its supply chain more efficient. However, there is much disagreement on the mechanism through which such competition pitching supply chain against supply chain will take place. The purpose of this thesis therefore, is to develop and conceptualize the notion of supply chain vs. supply chain competition, within the discipline of supply chain management. The thesis proposes that competition between supply chains may be carried forward via the use of competition theories that emphasize interaction and dimensionality, hence, encountering friction from a number of sources in their search for critical resources and services. The thesis demonstrates how supply chain vs. supply chain competition may be carried out theoretically, using generated data for illustration, and practically using logistics centers as a way to provide a link between theory and corresponding practice of this evolving competition mode. The thesis concludes that supply chain vs. supply chain competition, no matter the conceptualization taken, is complex, novel and can be very easily distorted and abused. It therefore calls for the joint development of regulatory measures by practitioners and policymakers alike, to guide this developing mode of competition.

Työntekijän näkökulmat ja oppiminen ulkoistusprojektissa : "Aluks pelkää muutosta ja sit pelkää, ettei mikään muutukaan."

The aim of this master s thesis was to clarify employees views on outsourcing. The main questions of the study were 1) How the employees dealt with the change created by outsourcing and what things they felt important when implementing the change? 2) What kind of organizational questions the employees paid attention to when moving from one organization to another? 3) What kind of management issues the employees brought up in the outsourcing process? and 4) How the employees reflected change while experienced outsourcing? The theoretical foundations of the study were Jack Mezirow s theory of transformational learning and Yrjö Engeström s theory of expansive learning. The management of outsourcing was viewed by John P. Kotter s change management model. Research casted light on transformation and learning on four levels of analysis: on individual, organizational and management levels and on the level of reflection. The target of the study were the outsourced employees, who were moved from a Finnish public corporation to a private ITC organization along with the services they produce. The study material was eleven interviews from the outsourced employees. The study was implemented by fenomenographical theme analysis. The analysis revealed results in all four levels. On the individual level the main results were the importance of systematic and open information, meaning of social and technical integration and the feeling of employee s own control. On the organizational level the move from the public sector to private and all the changes in organizational culture and in fringe benefitswere fundamental. Organizational learning was analyzed with expansive learning theory. Expanding was perceived in four dimensions: temporal dimension, spatial dimension, responsibility-moral dimension and developmental dimension. On the management level the actions of one s closest manager was vital, as was the upper management s clear engagement and a shared view of the necessity of a change. In the data was found employees reflective talking, which was indicating the meaning of the change and which was interpreted from the learning point of view. According to this study, it is possible to identify and analyze reflective talk and that way have information about employees learning in an organizational change. It was prominent to notice how reflection in the process of outsourcing is extremely versatile and extensive.

Holistic Measures for Evaluating Prediction Models in Smart Grids

The performance of prediction models is often based on ``abstract metrics'' that estimate the model's ability to limit residual errors between the observed and predicted values. However, meaningful evaluation and selection of prediction models for end-user domains requires holistic and application-sensitive performance measures. Inspired by energy consumption prediction models used in the emerging ``big data'' domain of Smart Power Grids, we propose a suite of performance measures to rationally compare models along the dimensions of scale independence, reliability, volatility and cost. We include both application independent and dependent measures, the latter parameterized to allow customization by domain experts to fit their scenario. While our measures are generalizable to other domains, we offer an empirical analysis using real energy use data for three Smart Grid applications: planning, customer education and demand response, which are relevant for energy sustainability. Our results underscore the value of the proposed measures to offer a deeper insight into models' behavior and their impact on real applications, which benefit both data mining researchers and practitioners.

Implantação do Microsoft Project Server na Câmara dos Deputados : um estudo de caso e lições aprendidas

Atualmente não é possível pensar em gestão de projetos sem uma boa ferramenta apoiada em Tecnologia da Informação. Este trabalho estudou o processo de implantação e personalização do Microsoft Project Server na Câmara dos Deputados com o objetivo de avaliar se essa implantação se deu de maneira adequada segundo as melhores práticas de gestão de projetos, além de levantar as principais lições aprendidas no processo. Para tanto foi realizada uma pesquisa documental, em que, na primeira parte fez-se um apanhado em nível teórico das melhores práticas de gestão de projetos, notadamente PMBOK do PMI e a consulta a autores relevantes no contexto da gestão de projetos e da aprendizagem organizacional. Em um segundo momento foram pesquisados documentos relacionados ao processo de implantação como o edital de licitação, atas de reunião, atos normativos, dentre outros. Dos dados levantados foram identificadas falhas por parte da Câmara dos Deputados tais como elevado número de exigências de personalizações no ambiente e conhecimento limitado, a priori, da ferramenta, de suas capacidades e limitações. Por parte da contratada, observou-se falhas como desorganização, planejamento ruim, descumprimento de prazos, pendências, grandes atrasos e mudanças na equipe técnica do projeto. Pela análise dessas falhas, levantaram-se diversas lições aprendidas no processo. Por fim, concluiu-se que o processo de implantação do Microsoft Project Server na Câmara dos Deputados foi parcialmente adequado, pois apesar de ao final estar implantado de acordo com o escopo requerido, o processo como um todo apresentou muitas falhas.

Adaptive Scalable SVD Unit for Fast Processing of Large LSE Problems

Singular Value Decomposition (SVD) is a key linear algebraic operation in many scientific and engineering applications. In particular, many computational intelligence systems rely on machine learning methods involving high dimensionality datasets that have to be fast processed for real-time adaptability. In this paper we describe a practical FPGA (Field Programmable Gate Array) implementation of a SVD processor for accelerating the solution of large LSE problems. The design approach has been comprehensive, from the algorithmic refinement to the numerical analysis to the customization for an efficient hardware realization. The processing scheme rests on an adaptive vector rotation evaluator for error regularization that enhances convergence speed with no penalty on the solution accuracy. The proposed architecture, which follows a data transfer scheme, is scalable and based on the interconnection of simple rotations units, which allows for a trade-off between occupied area and processing acceleration in the final implementation. This permits the SVD processor to be implemented both on low-cost and highend FPGAs, according to the final application requirements.

A dinâmica dos espaços de cultura e lazer em Botafogo

O processo de terciarização da economia, o qual se faz presente claramente desde os primórdios da cidade do Rio de Janeiro, promoveu profundas transformações na organização interna da cidade, o que implica em novos usos do espaço urbano e gera novos processos na cidade, sobretudo em nossa área de estudo, o bairro de Botafogo. O processo de globalização provoca mudanças significativas na economia mundial. A cidade, portanto se insere nos espaços de globalização e, assim, sofre mudanças que vão se refletir em sua estrutura urbana. Desta forma, o setor de serviços é dinamizado, reforçando, então, o processo de terciarização. Neste caso, se torna evidente a relação entre urbanização as atividades terciárias. Percebe-se, assim, o surgimento de um novo modelo de urbanização, atrelado à presença destas atividades terciárias, as quais serão de suma importância para a constituição de novas centralidades no espaço interno da cidade, como é o caso de Botafogo. Neste contexto, os espaços de cultura e lazer têm fundamental importância, visto que atraem fluxos de consumidores, os quais se aproveitam da infraestrutura proporcionada pelo Estado, sobretudo de transportes, através do metrô e das inúmeras linhas de ônibus que servem o bairro. Os espaços de cultura e lazer possuem uma grande importância no contexto de renovação de Botafogo, uma vez que o bairro apresenta uma grande concentração de equipamentos desta natureza, os quais contribuem para uma maior circulação de pessoas em seu espaço interno. Observam-se duas áreas de concentração destes espaços em Botafogo, as quais se localizam nas extremidades e adjacências do principal eixo viário do bairro, onde podemos encontrar também onde se concentram serviços especializados. Então, podemos dizer que, na esfera do consumo, estes espaços de cultura e lazer surgem como resultado de ações públicas e privadas. Os espaços de cultura e lazer promovem uma nova dinâmica a Botafogo e gera impactos na economia urbana do Rio de Janeiro. São responsáveis pelo surgimento de uma nova centralidade no âmbito da cidade e contribuem, portanto, para o processo de reestruturação urbana da cidade do Rio de Janeiro

O herói e o inimigo no imaginário do jacobinismo brasileiro 1894/1897

Esta dissertação tem como objetivo compreender e analisar o jacobinismo brasileiro tendo como foco os anos de 1894 até 1897. Pretende-se perceber como esse grupo conseguiu construir um projeto de personalização do poder em torno do Marechal Floriano Peixoto em momentos críticos da história República brasileira: durante a Revolta da Armada de 1894; no momento de transição do governo militar para o governo civil de Prudente de Moraes em 1894/95; e na ocasião da morte do Marechal Floriano Peixoto em 1895. Para tanto, o estudo propõe uma reflexão sobre a utilização do discurso jornalístico como instrumento na fabricação da imagem dos revoltosos da Marinha como restauradores monarquistas e de Floriano como herói da República, buscando assim, perceber igualmente a dinâmica de sua elaboração e as suas repercussões na sociedade brasileira. Chegaremos a conclusão que as forças jacobinas enfraqueceram no momento do atentado a Prudente de Morais em 1897, mas seus discursos ainda tiveram eco na primeira metade do século XX na República brasileira.
