As technological advances throughout the field of satellite geodesy improve the accuracy of satellite measurements, numerical methods and algorithms must be able to keep pace. This becomes increasingly important for high precision applications, such as high degree/order gravity field recovery. Currently, the Gravity Recovery and Climate Experiment's (GRACE) dual one-way microwave ranging system can determine changes in inter-satellite range to a precision of a few microns; however, with the advent of laser measurement systems nanometer precision ranging is a realistic possibility. With this increase in measurement accuracy, a reevaluation of the accuracy inherent in the numerical integration algorithms is necessary. This study attempts to quantify and minimize these numerical errors in an effort to improve the accuracy of modeling and propagation of various orbital perturbations; helping to provide further insight into the behavior and evolution of the Earth's gravity field from the more capable gravity missions in the future. The numerical integration errors are examined for a variety of satellite accelerations. The propagation of orbits similar to those of the GRACE satellites using a gravitational model that assumes the Earth is a perfect sphere show integration errors, using double precision numerical representations, on the order of 1 micron in inter-satellite range and 0.1 nanometers per second in inter-satellite range-rate. In addition, when the Earth's gravitational field is formulated in spherical harmonics these numerical integration errors begin to contaminate signals to due harmonics approximately above degree 220, for an orbit at GRACE altitudes. Also, when examining the effect of mass anomalies on the Earth's surface, simulated as point masses, it is apparent that numerical integration methods are easily capable of resolving point mass anomalies as small as 0.05 gigatonnes. Finally, a numerical integration procedure is determined to accurately simulate the effect of numerous, small step accelerations applied to the satellite's center of mass due to misalignment and misfiring of the attitude thrusters. Future studies can then use this procedure as a metric to evaluate the accuracy and effectiveness of an accelerometer in reproducing these non-gravitational forces and how these errors might affect gravity field recovery. / text

This MFA thesis document explores the development of my acting craft and artistic development over a three-year period of intensive graduate training. The document includes an in-depth discussion of the preparation, rehearsal, and performance process of my culminating graduate production – Suzan Zeder’s The Edge of Peace – as it relates to my approaches to acting. The document also includes a discussion of various other areas of my acting process, including the importance of bringing my authentic self to every role, letting go of results, and the integration of body, voice, heart, and mind as well as the productions and experiences in my graduate work that proved essential to the development of these practices. / text

This thesis looks at justice and home affairs (JHA) policy-making in the European Union (EU). JHA refers to those areas which have traditionally been the domain of interior and justice ministries on the national level and which are now dealt with on the EU level on the basis of the Treaty on European Union (TEU) and includes areas such as immigration and asylum, visa policy and police co-operation. In short, this thesis aims to examine why the governments of the member states chose to start co-operating on these issues within the EU, what the nature of this co-operation is and what does it tell us about the EU in general. The thesis looks firstly at the forms of JHA co-operation prior to the TEU and how this led to the national governments deciding to give it a Treaty basis within the EU. There is then an account of how the negotiations on the TEU developed and resulted in JHA being governed by a set of Treaty provisions quite different to those for other policy areas. This is followed by two case studies looking in detail at how JHA policy was made after the TEU entered into force; these deal with visa policy and immigration and asylum. To help in this, two theoretical approaches, taken from political science studies of European integration, are used, namely neofunctionalism and liberal intergovernmentalism. These allow us to identify the extent to which the same processes and factors influence JHA policy-making as in more traditional areas of Community policy-making, and allow for conclusions to be drawn on what JHA policy-making can tell us about wider issues of European integration.

This thesis investigates the changing boundaries of the firm. Drawing on a study of the aircraft engine industry, it explores the managerial choices faced by firms in the development of complex products. The thesis builds on the literature on the resourcebased view of the firm, and studies on inter-firm division of labour. It integrates comparative quantitative analysis and case study methods. The thesis shows that despite the increasing use of collaborative agreements, aircraft engine manufacturers maintain a broad and deep set of in-house technological capabilities. Collaborative agreements are used to complement in-house technological capabilities and as a means to maintain systems integration capabilities. The thesis also shows that the aircraft engine industry is characterised by (a) increasing product modularization, often entailing a greater division of labour across firms at the product level, and (b) active co-ordination by engine manufacturers at the technological level. These two phenomena demonstrate that the technological boundaries of the firm differ fundamentally from the boundaries of the firm as defined by make-buy decisions. Outsourcing of components does not necessarily entail outsourcing technologies. These findings challenge current managerial prescriptions that suggest that firms should focus on a few technological capabilities. They also challenge the literature that argues that modularity should inform product design as well as firms' technology bases. The thesis proposes a framework to analyse the boundaries of firms developing complex products. Focusing on their role as systems integrators, it identifies two key dimensions of systems integration: synchronic and diachronic. Synchronic systems integration refers to the range of in-house technological capabilities of engine manufacturers required to set the concept design, decompose it, co-ordinate the network of suppliers, and re-compose the engine within a given product architecture. Diachronic systems integration refers to engine manufacturers' capabilities to envisage different paths of product architectures to meet evolving customer and regulatory requirements.

Integration process of people with disabilities has become very important problem. The integration of hearing impaired students into high education has become very common. Nevertheless this process has never been evaluated. The aim of this work is to study the literature that displays all the processes of integration especially regarding people with hearing loss. The survey has been made regarding the integration of people with hearing loss. During it three target groups have been questioned: hearing impaired students, professors and sign language interpreters. This survey evaluated the integration process and detected next problems: • the quality of sing language interpreting is low; • there are not enough dividable materials for these students; • hearing students and professors are not ready to communicate with these students; • not enough visual means are used in teaching process. The liquidation of these problems might increase the integration process of hearing impaired students into high education.

Syftet med denna studie är att belysa språkets betydelse vid integrering av nyanlända invandrarelever. Jag har undersök hur vida eleverna uppfattar sitt mottagande i den svenska skolan och hur eller om lärare kartlägger elevens språk- och kunskapsutveckling. Resultaten är baserade på information från personintervjuer och hur denna information korrelerar med min valda teori. Jag använde ett teoretiskt ramverk av Lev Semjonovitj Vygotskij som är en erkänd pedagogisk teoretiker. Resultaten av min studie visar att svaren från mina intervjuer stämmer väl överens med min valda teori: att omgivning och utveckling går hand i hand. Jag har kommit fram till att mottagande, kartläggning och integration är av största betydelse för den språkliga utvecklingen hos en nyanländ invandrarelev och dess fortsatta integration i det svenska skolsystemet då ett barns utveckling har visat sig ske i samspel med deras omgivning. Nyckelord: Mottagande, Kartläggning, Nyanlända invandrarelever, integration / The purpose of this study is to highlight the importance of language in the integration of newly arrived immigrant students . I examine how the students perceive their reception in the Swedish school and how or if the teacher charts the student's language and knowledge . Results are based on information from personal interviews and how this information correlates with my chosen theory. I used a theoretical framework of Lev Semenovich Vygotsky , a recognized educational theorists .   The results of my study show that the responses from my interviews is consistent with my chosen theory : that environment and development go hand in hand. I have concluded that the receipt , identification and integration is of paramount importance to the linguistic development of a newly arrived immigrant students and its continued inclusion in the Swedish school system when a child's development has been shown to occur in interaction with its environment.Keywords: Reception,Mapping, newly arrived immigrant students ,integration

Sammanfattning: Syftet med vår uppsats är att belysa identiteten och den kulturella tillhörigheten hos andra generationens invandrare. Vi vill belysa deras syn i fråga om identitet, integration och omgivning. Kvalitativa intervjuer har utförts för att få svar på våra frågeställningar och tre personer från Malmö samt två personer från Skellefteå och en person från Piteå har ställt upp på denna undersökningen. Dessa intervjuer har sedan analyserats och diskuterats med inspiration av essentialismen, konstruktionismen samt den postkoloniala teoribildningen. Utöver dessa inriktningarna ligger fokus på identitet och identitetsskapande teorier eftersom en stor del av syftet med studien är att belysa hur intervjupersonerna ser på sin identitet. Intervjupersonerna har alla gemensamt att de föddes och växte upp i Sverige samt att de har minst en förälder med utländskt bakgrund. Intervjupersonerna blev tillfrågade en rad olika frågor som granskades efteråt med hjälp av olika teoretiska utgångspunkter. Slutsatserna blev att andra generationens invandrare skapar tillhörighet tillsammans med familjen. De ser sig själva som integrerade svenska individer.

I Sverige föreligger en ringa forskning som berör amatörboxningens sociala betydelse. Detta gäller även den internationella arenan. En generell uppfattning är att boxning är en sport som mestadels utövas av grupper som har sina rötter i lägre sociala klassen. Den ringa forskning som finns visar att personer som söker sig till amatörboxning ofta kommer från en segregerad miljö med begränsade ekonomiska resurser. I vissa fall avviker de från samhällets normer. Anledningen till det kan grunda sig på brister i utbildning och kanske även ett kriminellt beteende. Forskare menar att boxning, inom ramen för en form av socialt arbete, kan hjälpa ungdomar som befinner sig i riskzon. Vår artikel har haft som syfte att kartlägga miljöer ur vilka amatörboxare rekryteras och när de har rekryterats, redovisa och diskutera vilka upplevelser av livskvalité som gäller för dem i dagsläget. För att uppnå syftet med vår studie har vi använt och bearbetat en inom projektet ’En rak vänster’ tidigare genomförd datainsamling. Resultatet av vår undersökning visar att amatörboxning kan uppfattas som ett verktyg för integration i samhället.
