Syftet med denna masteruppsats är att undersöka bostadsområdet Holma, dess förutsättningar och hur det upplevs av befolkning och verksamma i området, samt att analysera och diskutera området utifrån teoretiska resonemang kring plats, urbanitet och grannskap. Vidare är förhoppningen att kunna identifiera resurser för främjandet av gemenskap och hållbar förbättring. Arbetet skrivs utifrån ett socialkonstruktionistiskt perspektiv där en premiss är att människor genom sitt agerande formar mening och att detta agerande i sig påverkas av sociala strukturer. Det empiriska arbetet utgörs av etnografiska studier som analyseras utifrån nämnd teoretisk bas. Studien mynnar ut i resonemang kring vikten av medborgarengagemang och långsiktighet i grundandet av intiativ i grannskapet. En viktig hållpunkt är att befolkningen bör ha möjlighet att själva identifiera och ha inflytande över sin plats då det är hos dem en grundlig kunskap om platsen finns. Examensarbetet visar hur de sociala resurser som verkar i området i högre grad bör användas för utvecklingen av ett gott grannskap. / The purpose of this master thesis is to investigate the residential area Holma, Sweden, its preconditions and how it is experienced by the people that reside and work there, and to analyze and discuss this from theoretical viewpoints regarding space, place, urbanity and neighborhood. Furthermore, the aim is to identify resources for the promotion of community and sustainable improvement. The work is written from a social constructionist perspective in which one premise is that people, through their actions form meaning and that this behaviour itself is influenced by social structures. The empirical work consists of ethnographic studies that are further analyzed through the previously mentioned theoretical basis. The study culminates in discussions about the importance of civic engagement and long-term perspective in the implementation of the initiatives. A major strong point is that people should have the opportunity to identify and have influence over their place, as thorough knowledge of a place is to be found through its people. The thesis shows how the social resources that operate in the field should be better used for development of a strong neighborhood and community.

<p>In this thesis, we extend the Ai-Zhang direction to the class of semidefinite optimization problems. We define a new wide neighborhood N(τ1 ,τ2 ,η) and, as usual, we utilize symmetric directions by scaling the Newton equation with special matrices. After defining the "positive part" and the "negative part" of a symmetric matrix, we solve the Newton equation with its right hand side replaced first by its positive part and then by its negative part, respectively. In this way, we obtain a decomposition of the usual Newton direction and use different step lengths for each of them.</p><p>Starting with a feasible point (X^0 , y^0 , S^0) in N(τ1, τ2 , η ), the algorithm terminates in at most 0(η√( κ∞n)log(1/ε) iterations, where κ∞ is a parameter associated with the scaling matrix and ε is the required precision. To our best knowledge, when the parameter η is a constant, this is the first large neighborhood path-following Interior Point Method (IPM) with the same complexity as small neighborhood path-following IPMs for semidefinite optimization that use the Nesterov-Todd direction. In the case when η is chosen to be in the order of √η, our complexity bound coincides with the known bound for classical large neighborhood IPMs.</p><p>To make this thesis more accessible to readers who are new in this area, we start with a brief introduction to IPMs and SDO. The basic concepts and principles of IPMs and SDO are presented in Chapter 2 and 3.</p> / Thesis / Master of Applied Science (MASc)
