Bostadsmarknaden i Sverige blir allt mer osäker. För studenter som söker bostad på sin studieort har det blivit vanligare att man måste hyra i andra hand. Vad innebär detta för studenterna? Hur kan de bo och skapa ett hem inom dessa villkor på en bostadsmarknad med tillfälliga boendeformer? Följande uppsats har att analyserat hur man kan skapa ett hem på denna typ av bostadsmarknad genom att tillämpa Tim Ingolds begrepp ”dwelling perspective”. Utifrån Rolands Paulsen bok ”En studie i oro” (2020) tar uppsatsen även upp en diskussion om hur vi hanterar att leva i en samtid där oro och en känsla av otrygghet är ständigt närvarande. Genom ett antropologiskt perspektiv på hemmet och att bo är denna uppsats en analys av hur studenter bor och skapar ett hem på en osäker bostadsmarknad.

Nel settore dell’Informazione Geografica (GI), esiste in generale un gap a livello europeo tra l’istruzione e la preparazione offerte dalle università e le competenze e capacità richieste sul mercato da aziende ed enti pubblici. Per far fronte alle nuove sfide poste dai continui sviluppi tecnologici in atto (basti pensare a temi quali Geo Big Data, posizionamento indoor, Internet of Things, ecc.) è perciò necessario introdurre nuove forme di collaborazione università-impresa. giCASES – Creation of a UniversityEnterprise Alliance for a Spatially Enabled Society (http://www.gicases.eu) è un’Alleanza per le Conoscenze, co-finanziata dal Programma UE Erasmus+, che affronta questo problema con l’obiettivo di sviluppare approcci innovativi e multidisciplinari all’insegnamento e all’apprendimento nel settore GI facilitando lo scambio, il flusso e la co-creazione di conoscenza. L’approccio consiste nello sviluppo collaborativo e condiviso, tra università ed imprese, di nuovi materiali didattici e processi di apprendimento basati su casi reali (case-based learning). In maniera innovativa rispetto alle tradizionali forme di collaborazione tra università ed imprese (spesso limitate a semplici tirocini e allo sviluppo di tesi presso le imprese), la collaborazione con le università finalizzata alla co-creazione di conoscenza si esplica sin dalla fase iniziale di progettazione del corso accademico e del processo di apprendimento. Il progetto, iniziato nel 2016 e formato da un consorzio di 14 partner da 8 diversi Paesi europei (con una componente bilanciata di università e imprese), ha visto una prima fase volta alla definizione della metodologia di case-based learning e alla progettazione dei casi di studio. Un questionario inizialmente distribuito tra università, imprese ed enti pubblici europei nel settore GI ha evidenziato che: a) la collaborazione tra il settore accademico e quello industriale è spesso organizzata in modo tradizionale; b) le competenze richieste dal mercato del lavoro (specialmente programmazione, analisi e modellazione spaziale) spesso non sono in linea con l’istruzione universitaria; c) l’apprendimento basato su casi reali è uno dei metodi suggeriti per rendere la preparazione degli studenti conforme alle richieste del mondo del lavoro. publishersversion published

Demands on the quality and reliability of volunteered geographic information have increased because of its rising popularity. Due to the less controlled data entry, there is a risk that people provide false or inaccurate information to the database. One factor that affects the effect of such updates is the structure of the database schema, which in this paper is described by network models. By analyzing GIS data models, we have found that their class diagrams have small-world properties and long-tailed distributions. Moreover, an analysis of the error and attack tolerance showed that the data models were robust against random errors but very fragile against attacks. In a network structure perspective, these results indicate that false updates on random tables of a database should usually do little harm, but falsely updating the most central cells or tables might cause big damage. Consequently, it may be necessary to monitor and constrain sensitive cells and tables in order to protect them from attacks

Uppsatsen handlar om second moverföretag och dess etablering på marknaden. Sju 2Mo-företag har intervjuats för att finna gemensamma drag i dess etablering i tre steg: förutsättningar, strategi och hinder. De flesta 2Mo-företagen har vid sin etablering haft tydliga komparativa fördelar gentemot sina respektive konkurrenter. Det framgår att de komparativa fördelarna lägre kostnad och differentiering har stor betydelse vid etableringsbeslutet. Det har varit svårt att identifiera huruvida företagens timing varit god. Timingen hos många av företagens måste ses ur ett längre tidsperspektiv för att kunna identifieras som bra eller dålig. När det gäller företagens strategier har de även här stämt väl in på referensramen och undersökningsmodellen. Många av strategierna finns här representerade hos flera företag. Vissa hinder som inte omfattats av referensramen har även framkommit i studien. Många av företagen har haft samma leverantörer som sina konkurrenter. Det har gjort att konkurrenterna kunnat motarbeta utmanarna via sina inarbetade leverantörsrelationer. Fenomenet väljer vi att kalla för indirekt motarbetning. Vidare har flera av företagen haft problem med tillgång till kapital, vilket hindrat dem i etableringen. Många har löst kapitalbristen genom att ta in externt kapital.

he International Energy Agency (IEA) Bioenergy aims at advancing bioenergy utilisation. In one of the current tasks, Techno-Economic Assessments for Bioenergy Applications 1998-99, the objectives are (1) to analyze bioenergy systems to support organisations working with products and services related to bioenergy, (2) to build and maintain a network for R and D organisations and industry, and (3) to disseminate data on advanced biomass conversion technologies. These IEA resources have been maintained and improved since the original studies in 1982. State-of-the-art, performance, and feasibility analyses of biomass to (heat and) electricity (CHP), and liquid, gaseous, and solid fuel systems have been carried out. This paper presents technical and economic feasibility studies carried out for several advanced biomass power and fuel conversion technologies in Austria, Canada, Finland, Sweden and the United States during 1998-99. The core technologies analysed include a flue gas condensing system for increased heat production integrated to a biomass boiler, fast pyrolysis for chemicals, small-scale steam boiler power plant compared with proposed new bio-power concepts, and fast pyrolysis liquid production for district heat production within a city.

A techno-economic assessment was carded out as part of the International Energy Agency (IEA) Biomass Agreement. The overall objective of the work was to identify the optimum process concept to be considered for testing in a possible international test facility. The participating countries were Canada, Finland, Sweden, and United States. The comparison of the processes was primarily based on estimated production costs of synthetic gasoline. Processes were also assessed based on their technical merits, and the availability of experimental data was one of the prime criterion for the selection of analysed process concepts. In an earlier study by IEA it was shown, that atmospheric flash pyrolysis and high pressure liquefaction are the preferred direct liquefaction concepts for the production of fuel oil substitutes from biomass. Direct liquefaction makes it possible to produce synthetic gasoline or diesel oil with high efficiency (around 50 % with wood feed, above 60 % with peat feed). This applies to both pyrolysis and high pressure processes. The atmospheric flash pyrolysis appears as the most economic one for wood feed. With present technology, the estimated ratio of the product cost and the product value (defined as average spot market price for 1977-1987) is about 2 for a wood price of USD 30/wet ton. High pressure liquefaction of peat is assessed to be more economic than atmospheric flash pyrolysis. However, the uncertainties with the high pressure concept are estimated to be greater than with pyrolysis. There seems to be development potential for both process concepts, allowing an estimated cost reduction of 25-40 % for the products. The most promising process for gasoline production by direct liquefaction of wood and peat is atmospheric flash pyrolysis. Both these approaches have considerable development potential, while research needs and uncertainties appear to be greater with high pressure liquefaction. Therefore, it can be recommended that further development of gasoline production to be focused on flash pyrolysis.
