Changes in written communications brought about by technology have led to a revolution in the concepts of literacy and, as a result, in students’ educational needs. However, teenagers appear to use technologies that involve new channels and text genres in the digital environment much more than in their everyday life than in an academic environment, because there is still too much distance between what schools offer students and their own reality. This article shows part of the findings of ethnographic and qualitative research in the line of new studies on teenagers’ critical literacy and vernacular writing practices in the asynchronous communication spaces online. The idea is to offer data and ideas to help overcome the current inertia and distance between some educational activities and young people’s communicative needs

Nuclear magnetic resonance (NMR) is one of the most versatile analytical techniques for chemical, biochemical and medical applications. Despite this great success, NMR is seldom used as a tool in industrial applications. The first application of NMR in flowing samples was published in 1951. However, only in the last ten years Flow NMR has gained momentum and new and potential applications have been proposed. In this review we present the historical evolution of flow or online NMR spectroscopy and imaging, and current developments for use in the automation of industrial processes.

Most Finnish periodical magazines have a website, often an online service. The objective of this thesis is to understand the magazines’ resources and capabilities and match them with online strategies’ goals and objectives. The thesis’ theoretical part focuses on explaining and classifying resources, capabilities, goals and objectives, and applying everything into Finnish magazine publishing context. In the empirical part, there is a comparative case study of four magazines. The findings indicate that with cooperating, advertising and community hosting capabilities magazines may utilize their human, brand, content and customer base resources. The resources can be further addressed to reach profitability, customer-centricity and brand congruency goals.

The objective of this thesis was to study the relationship between firstorder capabilities and online innovations. First-order capabilities can be divided into market and technology capabilities, and they play an important role in the production of innovations. The study was carried out in publishing industry, where many changes have taken place in the online environment during the last few years. In the empirical research, four companies were studied, two magazine publishers and two newspaper publishers. The analysis was done in two phases; first every case was analyzed alone and then the cases were compared in cross-case analysis. The most important finding was the positive impact of market capability to the production of online innovations. The study also increased understanding about the relationship between market and technology capabilities and online innovations in general.

Este artigo reconstrói os momentos principais dos trabalhos de Dieter Henrich sobre a filosofia teórica de Immanuel Kant. Henrich procura esclarecer e recuperar os fundamentos da teoria do conhecimento de Kant, dos quais seus seguidores teriam se distanciado, a partir da análise da dedução transcendental das categorias. De início, Henrich investiga a estrutura da prova na dedução, comparando a primeira e a segunda edição da Crítica da Razão Pura. Em seguida, Henrich investiga no argumento kantiano a relação entre o princípio de identidade da consciência de si, por um lado, e objetividade, por outro. Por fim, estendendo a comparação à Crítica da Razão Prática, Henrich elucida o programa e a metodologia na dedução, mostrando como o "fato" legitimador se torna o elemento fundamental.

O ano de 1851 marca o primeiro contato de Richard Wagner com a filosofia de Schopenhauer, logo seguido por sua proclamada e algo surpreendente "conversão" ao schopenhauerianismo. Vinte anos depois, essa adesão é reafirmada em "Beethoven", escrito festivo que contém um esboço de uma filosofia da música, apresentada pelo compositor como fundamentada na estética schopenhaueriana e que terá grande influência na elaboração da noção do dionisíaco, tal como aparece em "O nascimento da Tragédia", de Nietzsche. Meu trabalho pretende, em primeiro lugar, investigar em que medida a estética musical esboçada em "Beethoven" é de fato compatível com as teses estéticas de "O mundo como Vontade e representação". A constatação de certas incongruências entre as duas concepções estéticas dá então oportunidade a reflexões sobre o caráter das relações entre Wagner, Schopenhauer e o jovem Nietzsche.

O objetivo deste artigo é examinar como Montaigne retoma, na sua crítica das filosofias morais e, especialmente, da existência de leis naturais, a proposta por Sexto Empírico acerca do mesmo tema ao final das Hipotiposes Pirronianas. Pretendo mostrar que, para além das consideráveis similaridades, o modo como Montaigne relaciona razão, natureza e costume, confere um perfil próprio à sua reconstrução do pirronismo, particularmente visível na sua compreensão da oposição entre critério de verdade e critério de ação. Igualmente, sustento que essa distinção, proveniente do pirronismo, ocupará um lugar central na sua reflexão moral.

Este artículo se propone realizar un abordaje crítico de la ontología afirmativa de Gilles Deleuze a partir de las objeciones realizadas por Georg Hegel a Spinoza en su Ciencia de la lógica. La hipótesis de trabajo es que, dada la herencia spinozista del pensamiento de Deleuze, estas críticas pueden resultar pertinentes para reflexionar sobre algunos puntos fundamentales. De esta manera, se intenta contrariar la habitual tendencia de los estudios deleuzianos de trabajar en una clave anti-hegeliana, es decir, a partir de una separación teórica total con la problemática de Hegel. Se descarta la posibilidad de centrar las críticas de Hegel en torno a la sentencia "omni determinatio est negatio" o la imposibilidad de progresar desde la afirmación absoluta (por lo que el verdadero comienzo en Spinoza -y por tanto en Deleuze- sería la mera realidad empírica donde los elementos se vinculan de manera extrínseca, es decir, sin concepto). El punto de inconmensurabilidad es que Hegel afirma que es necesario que exista un movimiento de retorno (zurürckkehren) para que la afirmación no se degrade al punto de la disolución, mientras que Deleuze prefiere el movimiento de eterno retorno (ewige wiederkunft) como apertura insistente en el porvenir.

Neste texto, procuro encontrar as origens de um dos mais importantes conceitos de Gilles Deleuze, o conceito de Imagem-tempo. Este conceito remete-nos para os primeiros textos de Deleuze dedicados à filosofia de Espinosa e ao problema do autómato espiritual e relaciona-se directamente com o problema da passividade/actividade do espectador. Ou seja, o conceito crucial na sua filosofia do cinema, a Imagem-tempo, esconde uma importante reflexão sobre a Imagem cinematográfica como arte de massas, os (im)poderes do pensamento e o modo fascista de se pensar.

There are several filtration applications in the pulp and paper industry where the capacity and cost-effectiveness of processes are of importance. Ultrafiltration is used to clean process water. Ultrafiltration is a membrane process that separates a certain component or compound from a liquid stream. The pressure difference across the membrane sieves macromolecules smaller than 0.001-0.02 μm through the membrane. When optimizing the filtration process capacity, online information about the conditions of the membrane is needed. Fouling and compaction of the membrane both affect the capacity of the filtration process. In fouling a “cake” layer starts to build on the surface of the membrane. This layer blocks the molecules from sieving through the membrane thereby decreasing the yield of the process. In compaction of the membrane the structure is flattened out because of the high pressure applied. The higher pressure increases the capacity but may damage the structure of the membrane permanently. Information about the compaction is needed to effectively operate the filters. The objective of this study was to develop an accurate system for online monitoring of the condition of the membrane using ultrasound reflectometry. Measurements of ultrafiltration membrane compaction were made successfully utilizing ultrasound. The results were confirmed by permeate flux decline, measurements of compaction with a micrometer, mechanical compaction using a hydraulic piston and a scanning electron microscope (SEM). The scientific contribution of this thesis is to introduce a secondary ultrasound transducer to determine the speed of sound in the fluid used. The speed of sound is highly dependent on the temperature and pressure used in the filters. When the exact speed of sound is obtained by the reference transducer, the effect of temperature and pressure is eliminated. This speed is then used to calculate the distances with a higher accuracy. As the accuracy or the resolution of the ultrasound measurement is increased, the method can be applied to a higher amount of applications especially for processes where fouling layers are thinner because of smaller macromolecules. With the help of the transducer, membrane compaction of 13 μm was measured in the pressure of 5 bars. The results were verified with the permeate flux decline, which indicated that compaction had taken place. The measurements of compaction with a micrometer showed compaction of 23–26 μm. The results are in the same range and confirm the compaction. Mechanical compaction measurements were made using a hydraulic piston, and the result was the same 13 μm as obtained by applying the ultrasound time domain reflectometry (UTDR). A scanning electron microscope (SEM) was used to study the structure of the samples before and after the compaction.

O propósito deste estudo retrospectivo foi avaliar o padrão de utilização do sistema de exercícios on-line, facultativos, assíncronos, para o apoio à aprendizagem da disciplina Medicina Legal e Deontologia Médica na Universidade de Brasília. Os sujeitos foram 38 alunos que cursaram a disciplina no segundo semestre de 2005. O sistema oferecia conteúdos textuais e imagens que podiam ser acessados anonimamente. Para a resolução dos exercícios do tipo "verdadeiro" ou "falso", alguns com imagens, era necessário que os alunos se identificassem por senha, o que permitiu o monitoramento. Os resultados mostraram que 32 alunos (84%) realizaram exercícios on-line, com uma média de 183 respostas por aluno, entre os que aderiram; 52% dos exercícios foram resolvidos nas últimas 24 horas antes da prova; 62,3% dos exercícios foram resolvidos entre 19h e 01h. Conclui-se que os alunos, num sistema facultativo, concentram seus esforços na véspera da prova, o que diminui a eficiência do sistema, sugerindo que técnicas de motivação para o uso regular desse tipo de sistema devem ser implementadas.
