PANA V : Evaluation of a Literacy Project

PANA V Evaluation of a Literacy ProjectSUMMARY AND CONCLUSIONSThis evaluation set out to explore the impact of the literacy work carried out through PANA V. It focussed on clarifying effects such as empowerment and poverty reduction in relation to the civil society. Two specific objectives were to evaluate the methodological approach and the didactic materials and to evaluate the sustainability of the project.Although the focus of the evaluation has been PANA V, the project has been evaluated in its context, as one in a series of five projects located in Rwanda ten years after the war and genocide. The conclusion will consider future plans in this field.The evaluator has striven to create a holistic picture of the effects of the project, although the given time for the evaluation was short. Only three weeks were spent in the field study and only ten days in the actual field. Although there were some organisational and logistic problems, as is common when carrying out a study like this in a poor country, many literacy sites were visited and quite many participators were interviewed. The overall impression from the study is overwhelmingly positive. So many people commit themselves in this task of teaching Rwandans reading, writing and numeracy. Despite harsh conditions learners strive to learn and group leaders devote themselves to the task. Many leaders on different levels try their very best to manage their difficult and demanding task. The main objective was to explore the impact of the project on poverty reduction, particularly on empowerment and strategies for everyday life. Women were to be regarded particularly. From the results it is clear that the project has a strong, positive impact both on poverty reduction and empowerment of marginalised groups. Among those who have benefited from the alphabetisation are mainly women. Unfortunately, when it comes to leaders in PANA, who may also be said to have benefited from the project, only a small minority is women. This is something that is recommended that it be reconsidered inside the organisation. As a majority of the targeted learners are women, and as the economic and social situation of women in Rwanda is generally weak, this is a question that I recommend the Pentesostal church and ADEPR to look particularly into. With many women being single breadwinners of their households, it is important that also women get access to positions that may bring benefits of different kind.It is also clear that the project has positive effects for the civil society. In the present situation in Rwanda, during the process of reconciliation and rapid progress, basic education for the poor majority is a democratic issue. In a country with a plethora of internet-cafés in the capital and a small minority that use cars and mobile-telephones to communicate nation-wide, it is of outmost importance that the majority acquires basic education, of which literacy is a central part. To strengthen the civil society in Rwanda literacy is important. One central issue is then that Rwanda develops toward becoming a country where literacy is used for the benefit of the citizens and it is a democratic issue that all citizens get an opportunity to participate. Crucial for this is that strong efforts are put into primary schools nation-wide. Literacy projects for adults, like PANA, may only complement these efforts, but they constitute important and necessary complements. Other relevant ways to promote literacy are campaigns in Radio and TV and through cultural events such as festivals, music and theatre. News papers, magazines and books are natural parts of such campaigns as well as adult education. As stated under the results not much can be said about the didactics in this evaluation. On the whole the methodology and the materials fill their function well and receive a high reputation. As people learn to read and write under very simple conditions, obviously the approach is appropriate. A few suggestions may be given from the study:•Focus groups leaders’ attention on clearness, that they show very clearly what is to be read. Good structuring is probably of great importance for many learners.•Make clear what is tested in the tests and consider the possibility to use a holistic test that would be more congruent with the methodology. The possibility to use only one grade, pass, would enable a more practical test, such as reading a short, relevant text, writing something relevant and solving practical mathematic problems. Avoid tests that demand school knowledge.•Avoid using methaphors such as “fight against illiteracy” and connections between illiteracy/literacy and darkness/light. It is not true that illiteracy causes bad things and that literacy only brings good. •Be prepared that it may be more difficult in the future to achieve the goals as it may be the case that the early learners where the ones who achieved easily. The goal of “literacy in six month” in PANA will probably hold only for some learners but also those who do not manage in six months need literacy skills.A third objective was to secure sustainability. As for sustainability of the project in itself, and of the literacy process, the main conclusion is that there is a good potential. The commitment and devotedness among many involved in PANA proves good. One weakness is individual leaders in ADEPR who do not see this as an important task for the Pentecostal church in Rwanda. Other weaknesses are the unwillingness to mention explicitly the wish, for example among group leaders, to get some kind of incentive and the fear of loosing believers by cooperation with other organisations. A higher degree of transparency in this issue would probably solve some irritations and tensions.As for the sustainability of the literacy skills much may be done to improve. The acquired skills seem to be comparably relevant. The level achieved, and the level tested, may be defined as basic literacy skills, consisting of basic reading, writing and numeracy skills. However, these skills are very restricted and there is a high risk that the skills will decline, which means that there is a high risk that people will forget how to read and write because of lack of exercising. From these conclusions a few suggestions for future development will be given.

Road network and GPS tracking with data processing and quality assessment

GPS technology has been embedded into portable, low-cost electronic devices nowadays to track the movements of mobile objects. This implication has greatly impacted the transportation field by creating a novel and rich source of traffic data on the road network. Although the promise offered by GPS devices to overcome problems like underreporting, respondent fatigue, inaccuracies and other human errors in data collection is significant; the technology is still relatively new that it raises many issues for potential users. These issues tend to revolve around the following areas: reliability, data processing and the related application. This thesis aims to study the GPS tracking form the methodological, technical and practical aspects. It first evaluates the reliability of GPS based traffic data based on data from an experiment containing three different traffic modes (car, bike and bus) traveling along the road network. It then outline the general procedure for processing GPS tracking data and discuss related issues that are uncovered by using real-world GPS tracking data of 316 cars. Thirdly, it investigates the influence of road network density in finding optimal location for enhancing travel efficiency and decreasing travel cost. The results show that the geographical positioning is reliable. Velocity is slightly underestimated, whereas altitude measurements are unreliable.Post processing techniques with auxiliary information is found necessary and important when solving the inaccuracy of GPS data. The densities of the road network influence the finding of optimal locations. The influence will stabilize at a certain level and do not deteriorate when the node density is higher.

On processing GPS tracking data of car-movements in Borlänge, Sweden

The advancement of GPS technology enables GPS devices not only to be used as orientation and navigation tools, but also to track travelled routes. GPS tracking data provides essential information for a broad range of urban planning applications such as transportation routing and planning, traffic management and environmental control. This paper describes on processing the data that was collected by tracking the cars of 316 volunteers over a seven-week period. The detailed information is extracted. The processed data is further connected to the underlying road network by means of maps. Geographical maps are applied to check how the car-movements match the road network. The maps capture the complexity of the car-movements in the urban area. The results show that 90% of the trips on the plane match the road network within a tolerance.

A data driven approach for automating vehicle activated signs

Vehicle activated signs (VAS) display a warning message when drivers exceed a particular threshold. VAS are often installed on local roads to display a warning message depending on the speed of the approaching vehicles. VAS are usually powered by electricity; however, battery and solar powered VAS are also commonplace. This thesis investigated devel-opment of an automatic trigger speed of vehicle activated signs in order to influence driver behaviour, the effect of which has been measured in terms of reduced mean speed and low standard deviation. A comprehen-sive understanding of the effectiveness of the trigger speed of the VAS on driver behaviour was established by systematically collecting data. Specif-ically, data on time of day, speed, length and direction of the vehicle have been collected for the purpose, using Doppler radar installed at the road. A data driven calibration method for the radar used in the experiment has also been developed and evaluated. Results indicate that trigger speed of the VAS had variable effect on driv-ers’ speed at different sites and at different times of the day. It is evident that the optimal trigger speed should be set near the 85th percentile speed, to be able to lower the standard deviation. In the case of battery and solar powered VAS, trigger speeds between the 50th and 85th per-centile offered the best compromise between safety and power consump-tion. Results also indicate that different classes of vehicles report differ-ences in mean speed and standard deviation; on a highway, the mean speed of cars differs slightly from the mean speed of trucks, whereas a significant difference was observed between the classes of vehicles on lo-cal roads. A differential trigger speed was therefore investigated for the sake of completion. A data driven approach using Random forest was found to be appropriate in predicting trigger speeds respective to types of vehicles and traffic conditions. The fact that the predicted trigger speed was found to be consistently around the 85th percentile speed justifies the choice of the automatic model.

Subcultura tuning: a identidade estendida na personalidade de automóveis

The admiration of people for automobiles has been known and revealed for many years all over the world. Being through academic studies, proprietor declaration and admirers, the automobile is an object of desire, admiration, love, passion, dream, pride and accomplishment which, with all of this, promotes various types of feelings with the identification, discrimination, expression and the projection of identity. This research was based on the theories about consumers¿ behaviors, self-concept and extended self. It'll be approached in a qualitative and exploratory way the personal behavior of the consumers who personalizes their automobile, the consumer Tuning. The Objective of this project is to explore how the ¿Tuners¿ use a personalized car to construct their social identity. Supplementary, was explored which factors commence and initiated the extension process of self-automobile and also, how they connect with their object and why this relationship is establish this way. Seven people were interviewed of the male sex between 19 and 33 years old, living in the stated of Rio de Janeiro and São Paulo, during the period of September and October of the year 2007. The results observed were that the cars, like objects, can literally broaden its owner¿s personality. The creation process, sustentation and nutrition of the ¿Self¿ through the car can be observed in the personalization of their own cars, with this, using like the middle and end. It was also observed that the begin of the personalization phenomenon of automobiles in Brazil is began, mainly, in the 21 century with the diffuser of the culture, the cinema, evince even more, processes that already existent in the extension of the personalized cars. Observing that a personalized automobile tents to be in a free way, like a distance, when possible, from intransigence of models or imposition of the ways to be accomplished. Definitively, stories like: ¿My car is just a useful way to travel which I use only when necessary¿ will not be found in this research.

Dinâmica molecular investigada com pulsos de femto-segundos

Técnicas experimentais de óptica não-linear resolvidas no tempo são capazes, em diversas situações, de fornecer mais informações sobre a dinâmica e estrutura molecular do que técnicas sem nenhuma resolução temporal. Nesta tese investigou-se três sistemas com técnicas espectroscópicas resolvidas no tempo, utilizando pulsos ultra-curtos de um sistema LASER amplificado, baseado em cristal de Ti:Safira, e de amplificadores ópticos paramétricos. Para este estudo foram implementadas e analisadas quatro diferentes técnicas espectroscópicas resolvidas no tempo: Espalhamento Raman anti-Stokes Coerente (CARS), Espalhamento hiper-Rayleigh Resolvido no Tempo (TRHRS), Bombeio-Prova e Bombeio- Depleção-Prova. O três sistemas investigados apresentam um grau crescente de complexidade nas suas dinâmicas e interações com o meio. O primeiro dos sistemas estudados foi a dinâmica da molécula de H2 no regime de impacto, na presença de moléculas e átomos perturbadores (N2 e He). Foi possível determinar, pela primeira vez, coeficientes de alargamento para o ramo Q devido à colisões entre H2+H2 utilizando a técnica de CARS resolvido temporalmente, bem como novos coeficientes para o deslocamento das linhas. O emprego da mesma técnica em sistemas binários lançou mais luz sobre a possibilidade de existir alguma não-homogeneidade em tais tipos de colisões. O segundo experimento investigou a dinâmica de relaxação orientacional da acetonitrila em solução utilizando a nova técnica de TRHRS; esta foi desenvolvida e testada com sucesso pela primeira vez neste trabalho. Um modelamento teórico mostra que dentro do modelo de Debye para a difusão rotacional, tempos associados ao terceiro momento do tempo de difusão (τ3) e ao primeiro momento (τ1) devem ser observados. Os resultados experimentais para a acetonitrila apresentam um decaimento consistente com este modelo (τ3~850 fs), concordando também com valores derivados de resultados experimentais e teóricos obtidos por outros métodos. Além disso, também foi observado experimentalmente uma segunda componente mais rápida (~50 fs), que não pôde ser explicada dentro do modelo de difusão rotacional livre. Esta componente foi atribuída a efeitos reorientacionais coletivos em conjunto com efeitos de superposição temporal de pulsos. A interpretação do sinal desta nova técnica foi testada com sucesso realizando o experimento em tetracloreto de carbono.O terceiro sistema investigado foi a dinâmica de relaxação de energia intramolecular de carotenóides. A principal questão, da vii existência ou não de estados eletrônicos adicionais, foi abordada utilizando uma modificação da técnica de Bombeio e Prova, denominada de Bombeio-Depleção-Prova. A técnica de Bombeio-Depleção-Prova foi pela primeira vez utilizada em carotenóides, possibilitando observar dinâmicas nunca vistas por qualquer outra técnica experimental. Dentro da resolução temporal dos experimentos realizados, a presença de novos estados eletrônicos em carotenóides livres em solução é descartada. Além disso, uma nova ferramenta de análise de dados foi desenvolvida. A análise de alvos espectrais baseada em um algoritmo evolutivo trouxe mais argumentos para o modelo clássico de três níveis. A dinâmica de carotenóides livres em solução foi comparada com sua dinâmica quando inseridos no complexo fotossintético de coleta de luz (LH2) da bactéria púrpura, utilizando para isso a técnica de Bombeio e Prova. Os resultados obtidos mostram um sistema de níveis de energia mais complexo do que quando o carotenóide está livre em solução. Esta modificação devido ao ambiente é possivelmente gerada pela quebra de simetria do carotenóide quando inserido no complexo LH2, possibilitando o cruzamento entre sistemas (singlete-triplete).

Uso de operações estruturadas para financiamento de projetos no setor sucroenergético brasileiro

O setor sucroenergético brasileiro passou por um intenso ciclo de crescimento nos últimos anos. Ainda assim, a demanda de etanol no país continua a superar a capacidade de produção, principalmente devido ao sucesso dos carros flex-fuel. As usinas voltaram também a atenção à bioeletricidade, aos alcoolquímicos e a diversos outros subprodutos e coprodutos do processo de produção de açúcar e etanol. Por estes motivos, se faz necessária a realização de maiores investimentos em ampliação e modernização das atuais usinas, e no aumento do número de unidades de produção. Para que tais investimentos sejam realizados da maneira mais eficiente, é necessário conhecer todas as opções de linhas de crédito disponíveis. Uma delas, pouco usada e com bons resultados é a Structured Project Finance. O presente trabalho tem como objetivo discutir o modelo de Structured Project Finance e apresentá-lo como uma possível alternativa de financiamento de projetos de usinas de açúcar e etanol no Brasil. Sua principal contribuição é apresentar uma alternativa de financiamento que agregue mais valor ao negócio.

Uma análise energética da cristalização por resfriamento na indústria da cana-de-açúcar

Os mercados dos produtos oriundos da cana-de-açúcar no mundo vêm sofrendo nos últimos anos mudanças estruturais significativas. No cenário brasileiro, houve grande expansão da produção de cana-de-açúcar, impulsionados pela demanda dos carros flex –fuel, além da oportunidade de suprir o volume de açúcar que a União Europeia deixara de colocar no mercado mundial pela eliminação da subvenção aos exportadores de açúcar do bloco. As incertezas dos mercados exigem mudanças de estratégias de negócio, usinas projetadas para produção exclusiva de etanol, alteram sua estratégia para produção conjunta etanol e açúcar. Apesar dos processos comuns para produção de açúcar e etanol, não significa que essa mudança de estratégia seja fácil de ser efetivada, principalmente pelo aspecto energético. Estudos de processo de produção de açúcar mais eficientes energeticamente, com custos menores tem ganhado força na União Europeia, dentre elas a cristalização do açúcar por resfriamento. Vários cenários produtivos inclusive integrados a produção de etanol tem sido desenvolvidos ao longo dos anos. O objetivo do trabalho foi verificar por comparação de cenários, duas tecnologias de cristalização do açúcar (cozimento e resfriamento), em relação ao impacto nos excedentes de energia elétrica quando a produção de açúcar é adicionada a unidades que produzem somente etanol e energia elétrica. Por meio de simulações dos balanços térmicos dos cenários, observou-se uma restrição importante quando adotado a cristalização por cozimento, no que se refere aos volumes de excedentes de energia elétrica, e que pode ser minimizado se adotado o processo de cristalização por resfriamento, podendo assim ser uma alternativa quando se deseja mudar a estratégia do negócio, de produção exclusiva de etanol e energia elétrica para etanol, açúcar e energia elétrica.

Development and evaluation of a range anxiety-reducing business model for connected full electric vehicles

This thesis develops and evaluates a business model for connected full electric vehicles (FEV) for the European market. Despite a promoting political environment, various barriers have thus far prevented the FEV from becoming a mass-market vehicle. Besides cost, the most noteworthy of these barriers is represented by range anxiety, a product of FEVs’ limited range, lacking availability of charging infrastructure, and long recharging times. Connected FEVs, which maintain a constant connection to the surrounding infrastructure, appear to be a promising element to overcome drivers’ range anxiety. Yet their successful application requires a well functioning FEV ecosystem which can only be created through the collaboration of various stakeholders such as original equipment manufacturers (OEM), first tier suppliers (FTS), charging infrastructure and service providers (CISP), utilities, communication enablers, and governments. This thesis explores and evaluates how a business model, jointly created by these stakeholders, could look like, i.e. how stakeholders could collaborate in the design of products, services, infrastructure, and advanced mobility management, to meet drivers with a sensible value proposition that is at least equivalent to that of internal combustion engine (ICE) cars. It suggests that this value proposition will be an end-2-end package provided by CISPs or OEMs that comprises mobility packages (incl. pay per mile plans, battery leasing, charging and battery swapping (BS) infrastructure) and FEVs equipped with an on-board unit (OBU) combined with additional services targeted at range anxiety reduction. From a theoretical point of view the thesis answers the question which business model framework is suitable for the development of a holistic, i.e. all stakeholder-comprising business model for connected FEVs and defines such a business model. In doing so the thesis provides the first comprehensive business model related research findings on connected FEVs, as prior works focused on the much less complex scenario featuring only “offline” FEVs.

Fatores motivacionais da comunicação boca-a-boca eletrônica positiva entre consumidores no Facebook

O estudo objetivou investigar as motivações do comportamento de comunicação boca a boca positiva sobre produtos e marcas no site de redes sociais Facebook. Para tanto, foram desenvolvidas hipóteses de pesquisa e um modelo teórico para se entender as motivações da comunicação boca a boca positiva neste contexto. Para testar a validade do modelo proposto, um estudo de campo foi conduzido com 468 usuários do Facebook no Brasil. Os dados foram analisados por meio de modelagem de equações estruturais. Os resultados sugerem como motivos a preocupação com outros consumidores e o desejo de interação social, seguidos dos desejos de extravasar emoções positivas e de ajudar a empresa. O teste empírico deu suporte ao papel moderador da força dos laços sociais na relação entre preocupação com outros consumidores e o boca a boca positivo. Ao analisar variações no comportamento de boca a boca positivo em função do perfil demográfico, o estudo sugere que as mulheres são mais engajadas do que os homens e que publicam e compartilham, em média, uma maior variedade de categorias de produtos e marcas. Entretanto, a pesquisa sugere uma associação significativa entre a categoria de produto divulgada e sexo do consumidor. Desta forma, apesar das mulheres divulgarem, em média, uma maior variedade de produtos, os resultados sugerem que homens são mais engajados em algumas categorias específicas, como por exemplo, esporte, carros e motos. Com base nos resultados, são discutidas implicações teóricas e práticas, bem como sugestões para pesquisas futuras.

Quality change in Brazilian automobiles

In this paper I investigate the quality evolution ofBrazilian autos. To measure the quality evolution of Brazilian autos, I have assembled a data set for Brazilian passenger cars for the period 1960-1994, to which I have applied the hedonic pricing methodology. To the best of my k:nowledge, this is the first time an index of quality change has been constructed for the Brazilian automobile industry. The results presented here have two major implications. They allow a better -- ......... understanding of product innovation in Brazil's auto industry, and they provide a clearer explanation of the behavior of auto prices.

A influência da responsabilidade social empresarial na satisfação e fidelidade do cliente : um estudo com compradores de automóveis

This study presents an investigation of the influence of Corporate Social Responsibility (CSR) in customer s satisfaction and loyalty through a study with car s buyers, besides that, it aims to contribute to conceptual models of satisfaction and loyalty analysis by applying the model of Johnson et al. (2001), adapted for the introduction of variables of CSR and conscious consumption, in a car dealership in Natal / RN. The methodology has a descriptive quantitative approach and for the analysis results were applied statistical methods of simple and multiple linear regression analysis, descriptive analysis and exploratory analysis. The field research provided 90 valid forms. The results show that CSR affects the image of the company studied and is also one of the elements of the compound of satisfaction and loyalty. This study concludes that CSR should be considered in the strategic and marketing actions of firms
