Evidence has shown that Multisystemic Therapy (MST) an intensive family- and community-based intervention has been particularly effective in the treatment of youth with antisocial behaviour from ethnically diverse backgrounds. Although the process of change within MST has been explored, there is a dearth of research in looking at this for families from ethnic minority backgrounds. The current research aimed to address this gap by exploring the experiences of a sample of London based caregivers who had completed an MST intervention. A qualitative approach was adopted, using grounded theory methodology to explore ethnic minority caregiver experiences of MST and generate a model of the processes of engagement and change based on participants' accounts. Seven semi-structured interviews were carried out with caregivers from two London sites. The emergent model consisted of seven interacting theoretical codes. Three of these codes were organised around the process of engagement; deciding to engage with MST, becoming therapeutically aligned and considering cultural difference, and four related to the process of change; working within a safe and trusting relationship, therapist acting as cultural broker, empowering the parent and increased communication within and outside the family. The author makes novel suggestions relating to the specific mechanisms that are thought to underlie the process of engaging with MST, and highlights the importance of considering cultural difference in the initial stages of the MST intervention.

This quantitative research study focuses on the capabilities of ICT tools used by virtualteams and seeks to find out what, if any, correlation between the ICT tools capabilitiesand challenges that virtual teams face exist. The study addresses four prominent virtualteam challenges: forming trust and relationships, information overload, communicationbreakdown, lack of team synergy and cohesion. It analyses ICT tools and establishhypothesis using MST theory and the existing research in this field. The data analysis isconducted using Spearman’s Rho correlation. The findings show that the correlationbetween ICT tools usage and the challenges that virtual teams face are not statisticallysignificant to establish a link between virtual team challenges and ICT tools usage. Thiscould mean that a significantly larger sample is required to establish the link betweenthese two variables. It could also mean that the virtual team challenges need to be reevaluatedas the collected data suggests that the discussed challenges are rarelyexperienced by virtual teams. Therefore, further studies are needed in order to establishthe correlation between the virtual team challenges and ICT tools usage.

Aproximar-se das questões, em nível da formação contínua dos educadores Sem Terra, é confrontar-se com os conflitos que perpassam a dinâmica e o fazer pedagógico desse segmento social. O MST possui um projeto educacional em nível nacional que tem como meta, entre outras, a erradicação do analfabetismo dos que fazem o Movimento, o direito à escola pública e a formação de educadores. Este trabalho configura-se num processo que buscou conhecer como se materializa a formação contínua dos educadores do MST em um assentamento, e quais os princípios pedagógicos fundamentam essa formação. O estudo foi desenvolvido com os educadores da Escola Municipal de Ensino Fundamental Roberto Remige, no assentamento João Batista II, em Castanhal/PA. O trabalho caracteriza-se por uma abordagem qualitativa do tipo etnográfico e valeu-se de observação, análise documental e entrevistas como instrumentos metodológicos, numa perspectiva de análise histórica, baseada em Paulo Freire (1921-1997). A pesquisa fundamenta-se nas abordagens pedagógicas do ponto de vista do MST e de autores que estudam o tema, tendo como prioridade o pensamento do educador Paulo Freire (1921-1997). A decisão de tomar os estudos freireanos como referencial teórico deste trabalho deu-se pelo fato de ser um dos teóricos a quem o MST recorre com freqüência, pela sua contribuição na construção pedagógica das escolas, assim como nos estudos de formação inicial e contínua dos educadores nos assentamentos. O estudo resgata a história do MST, abrangendo-a da gênese à consolidação e territorialização, no Brasil, por considerar que é nessa dinâmica de ocupação da terra que estão inseridas as lutas pela democratização do ensino e pela formação de educadores para atender a demanda educacional nos assentamentos. Na continuidade, se detém sobre os princípios pedagógicos que fundamentam a formação contínua do educador Sem Terra, do ponto de vista do MST, em diálogo com o referencial teórico - a pedagogia freireana - articulados às formulações de outros autores acerca da formação contínua. Em seguida, a partir dos educadores entrevistados, o estudo apresenta a experiência dos educadores, no referido assentamento, acerca da formação contínua, discutindo a intencionalidade do ato de formar que subentende uma formação de dimensão política e ideológica, a partir do assentamento, organicamente vinculada à política traçada pelo coletivo nacional de educação do MST. Por fim, dada a complexidade do estudo, haja vista o contexto de lutas sociais e políticas em que se insere, são identificados os limites, alcances e perspectivas da formação contínua para educadores sem-terra do assentamento João Batista II. Os questionamentos apresentados se configuram como inquietações, que podem desencadear novas pesquisas acerca da educação nos movimentos sociais.

The insertion of this social movement in what is known as the virtual public sphere and the actions of this collective in the context of Cyber Democracy were observed. The objective was to understand how the virtual public sphere can be seen as an interesting space, capable of venting a multiplicity of voices that, often, do not find suitable conditions to express themselves in the off-line public sphere, but that, many times, through acting in the cyberspace, reach what is called overflowing : an intersection between two spaces (on and off) that point to practical results for the agent. Thus this paper was conjugated from the observation of three elements that organize it: the constituting of a virtual public sphere, Cyber Democracy as the new terrain that enables citizenship actions and the strategies organized by MST in order to act in this scenario. The principles of the Comprehensive Sociology guided the theoretical construction of this research; and the principles of Ethnography and Netnography, the empirical construction. Through these methodological options we have tried to identify the gains obtained by this collective from its actions in the virtual sphere and answer the following question: what does it represents for MST the organization of a website in which it can say about itself, directly to the receptor, without any intermediates? / O presente trabalho ? dedicado ? an?lise das estrat?gias de Comunica??o organizadas pelo Movimento dos Trabalhadores Rurais Sem Terra (MST) em sua p?gina oficial (www.mst.org.br). A partir desta an?lise observamos a inser??o do movimento social no que entendemos por esfera p?blica virtual, al?m de examinar as a??es desse coletivo no contexto da Ciberdemocracia. Nossa inten??o foi a de compreender como a esfera p?blica de car?ter virtual pode ser vislumbrada como um espa?o interessante, capaz de dar vaz?o a uma multiplicidade de vozes que, habitualmente, n?o encontra condi??es de express?o na esfera p?blica off-line, mas que muitas vezes alcan?a, atrav?s da atua??o no ciberespa?o, o que chamamos de transbordamento : uma intersec??o entre os dois espa?os (on e off) que aponta resultados pr?ticos para o agente em quest?o. Nesse sentido, conjugamos este trabalho a partir da observa??o de tr?s elementos que o organizam: a constitui??o de uma esfera p?blica virtual, a Ciberdemocracia enquanto novo terreno propiciador da a??o cidad? e as estrat?gias organizadas pelo MST para atuar nesse cen?rio. Os princ?pios da Sociologia Compreensiva foram as indica??es que nortearam a constru??o desta pesquisa no campo te?rico. No que tange ? pesquisa emp?rica, nos valemos da etnografia e da netnografia. Atrav?s dessas op??es metodol?gicas buscamos identificar os ganhos obtidos por este coletivo a partir de suas a??es no meio virtual procurando responder a seguinte indaga??o: o que representa para o MST, a organiza??o de um site em que pode dizer de si diretamente ao receptor, livre de intermedi?rios?.

A Igreja teve grande influência e participação na formação do MST, pois a partir da Teologia da Libertação é que a Igreja faz a ―opção preferencial pelos pobres‖, atribuindo ao pobre o papel de sujeito transformador de sua própria realidade social, trazendo, desta maneira, esperança à luta dos que não têm terra e impulsionando essas pessoas a lutarem pela reforma agrária. Além disso, a Igreja exerceu um papel fundamental na legitimação da luta pela terra no Brasil através da disseminação de uma ideologia político-religiosa, em que a Terra ―é uma dádiva de Deus‖, ―é um bem de todos‖. Sendo a organização e as formas de luta pela reforma agrária, desenvolvidas pelo MST, legitimadas pela Teologia da Libertação, torna-se objetivo central deste trabalho identificar as manifestações ideológicas da Teologia da Libertação na luta pela reforma agrária. A hipótese deste trabalho é a de que a ideologia da Teologia da Libertação, a qual é constituída por um conjunto de concepções, se manifesta nos discursos e nas práticas sociais dos moradores dos assentamentos 24 de Novembro e 25 de Outubro, justificando a luta pela reforma agrária e estruturando uma relação de Afinidade eletiva entre Igreja e MST. / This work presents an analysis of the ideological manifestations of the Liberation Theology in the agrarian reform fight. The church had great influence e participation in the MST formation, because it‘s from the Liberation Theology that the church does the ―preferential option for the poor‖, attributing to the poor the role of subject transformer of his own social reality, bringing, on this way, hope to the fight of the ones that not have land and stimulating these people to the agrarian reform fight. Moreover, the church exercised a fundamental part in the legitimating for the land fight in Brazil, through of the disseminating of a politic religious ideology, where the land ―is a God gift‖, ―is a common good‖. Being the organization and agrarian reform fight ways, developed by MST, legitimated by Liberation Theology, becomes the central objective of this work identify the ideological manifestations of the Liberation Theology in agrarian reform fight. The hypothesis of this work is that the Liberation Theology ideology's, which is constituted by a conceptions set‘s, it manifests in the speeches and social practices of the 24 de Novembro and 25 de Outubro settlements' dwellers, justifying the agrarian reform fight and structuring an elective affinity‘s relations between the church and MST.

<p>The aim was to develop, manufacture and evaluate diffractive lenses, or diffractive optical elements (DOE), for use in correlation with a camera to add perspective in pictures. The application is a miniaturized submarine developed in order to perform distant exploration and analysis in harsh and narrow environments. The idea is to project a laser pattern upon the observed structure and thereby add geometrical information to pictures acquired with an onboard CMOS camera. The design of the DOE-structures was simulated using the optimal rotational angle method (ORA). A set of prototype DOEs were realized using a series of microelectromechanical system (MEMS) processes, including photolithography, deposition and deep reactive-ion etching (DRIE). The projected patterns produced by the manufactured DOEs were found to agree with the simulated patterns except for the case where the DOE feature size was too small for the available process technology to handle. A post-processing software solution was developed to extract information from the pictures, called Laser Camera Measurement (LCM). The software returns the x, y and z coordinate of each laser spot in a picture and provides the ability to measure a live video stream from the camera. The accuracy of the measurement is dependent of the distance to the object. Some of the patterns showed very promising results, giving a 3-D resolution of ~0.6 cm, in each dot, at a distance of 1 m from the camera. Lengths can be resolved up til 3 m distance from the submarine.</p> / <p>Tillämpningen finns i en miniatyriserad ubåt framtagen för utforskning och analys av svåråtkomliga och trånga håligheter. Målet var att designa, tillverka och utvärdera en diffraktiv lins (DOE) för användning tillsammans med en kamera för att skapa perspektiv i bilder. Idén var att projicera ett lasermönster på objektet och därmed lägga till geometrisk information till bilderna tagna med CMOS kameran. Utformningen av DOE-strukturerna simulerades med the optimal rotational angle method (ORA). En uppsättning av prototyp DOE-linser tillverkades med hjälp av en serie mikrostrukturteknikprocesser, bland annat fotolitografi, deponering och plasmaetsning. Mönster projicerade med de tillverkade DOE-linserna stämde väl överens med önskade mönster, med undantag för de DOEs där strukturstorleken underskred processens begränsningar. En programvara, kallad Laser Camera Measurement (LCM), utvecklades för att extrahera information från bilderna. Programvaran returnerar x, y, och z koordinaterna för varje laserpunkt i en bild och ger möjlighet att mäta i en kontinuerlig videoström från kameran.  Mätosäkerheten är beroende av avståndet till objektet. Vissa mönster gav mycket lovande resultat, med en 3-D upplösning på ~0.6 cm, i varje punkt, på ett avstånd av 1 m från kameran. Längder kan upplösas upp till 3 m från kameran där ett så kallat far-field uppstår.</p> / DADU

<p>This thesis explores the potential of multifunctional silicon-based microsystems for advanced integrated nanospacecraft (AIN).

Thermal simulations support the expectation, of a thermally biased ICTM, that the module is capable of supporting this energy burst, by using the mechanisms of heat storage and heat switches, and still fulfilling the requirements imposed by AIN type of spacecraft. In addition, multiple functional surfaces for the ICTM are evaluated with respect to equilibrium temperature and process compatibility.

<p>Microsystem interfaces to the macroscopic surroundings and within the microsystems themselves are formidable challenges that this thesis makes an effort to overcome, specifically for enabling a spacecraft based entirely on microsystems. The NanoSpace-1 nanospacecraft is a full-fledged satellite design with mass below 10 kg. The high performance with respect to mass is enabled by a massive implementation of microsystem technology – the entire spacecraft structure is built from square silicon panels that allow for efficient microsystem integration. The panels comprise bonded silicon wafers, fitted with silicone rubber gaskets into aluminium frames. Each module of the spacecraft is added in a way that strengthens and stiffens the overall spacecraft structure.</p><p>The structural integrity of the silicon module as a generic building block has been successfully proven. The basic design (silicon, silicone, aluminium) survived considerable mechanical loads, where the silicon material contributed significantly to the strength of the structural element. Structural modeling of the silicon building blocks enables rapid iterative design of e.g. spacecraft structures by the use of pertinent model simplifications.</p><p>Other microsystem interfaces treats fluidic, thermal, and mechanical functions. First, solder sealing of microsystem cavities was demonstrated, using screen-printed solder and localized resistive heating in the microsystem interface. Second, a dismountable fluidic microsystem connector, using a ridged silicon membrane, intended for monopropellant thruster systems, was developed. Third, a thermally regulated microvalve for minute flows, made by a silicon ridge imprint in a stainless steel nipple, was investigated. Finally, particle filters for gas interfaces to microsystems, or between parts of fluidic microsystems, were made from sets of crossed v-grooves in the interface of a bonded silicon wafer stack. Filter manufacture, mass flow and pressure drop characterization, together with numeric modeling for filter design, was performed.</p><p>All in all this reduces the weight and volume when microsystems are interfaced in their applications.</p>

<p>Spacecraft on interplanetary missions or advanced satellites orbiting the Earth all require propulsion systems to complete their missions. Introducing microelectromechanical systems technology to the space industry will not only reduce size and weight of the propulsion system, but can also increase the performance of the mission.</p><p>Fluid handling systems are used in chemical and electric propulsion. Some components incorporated in a fluidic handling system are presented and evaluated in this work.</p><p>Microsystems are very sensitive to contamination. Reliable, robust, and easily integrated filters were modeled, manufactured, and experimentally verified.</p><p>A fluid connector, designed to withstand large temperature variations and aggressive propellants was manufactured and characterized. Similar designs was also be used as a thermally activated minute valve.</p><p>The feasibility of a cold gas system for precise attitude control has been demonstrated. Steps towards improving the performance (from specific im-pulse 45 s) have been taken, by the integration of suspended heater elements.</p><p>For electric propulsion, two thermally regulated flow restrictors have been characterized. These devices can fine-tune the propellant flow to e.g. an ion engine.</p><p>A single-use valve using a soldered seal has also been successfully dem-onstrated within a pressure range of 5 to 100 bar.</p><p>The microsystem-based propulsion systems of tomorrow’s spacecraft need to be demonstrated in space, in order to gain necessary credibility. </p>
