Volyminspirerat arbete i förskoleklassen - en prioriteringsfråga? : En studie om förskolelärares uppfattningar om volyminspirerat arbete
Syftet med denna studie är att få ökad insikt om hur förskolelärare uppfattar sitt eget arbete med att främja barns begreppsutveckling inom området volym. Syftet med studien är även att få ökad kunskap om vilka aspekter som påverkar den dagliga verksamheten inom området volym i förskoleklassen. Denna undersökning är baserad på intervjuer med sex förskolelärare, materialet har bearbetats och kategoriserats under fem stycken huvudrubriker som belyser olika aspekter av hur förskolelärarna uppfattar att de arbetar med området volym i förskoleklassen. Vi har valt att belysa denna undersökning ur ett sociokulturellt perspektiv. I vår analys har vi kommit fram till att det finns många olika aspekter som påverkar utformandet av verksamheten i förskoleklassen.
Gestaltning av boendelandskapet i gränsen mellan stad och land : exemplet Norränga i Lund
This is a 20 credit Master thesis within the landscape architecture education at the Institute for Landscape Planning at the Swedish University of Agricultural Sciences at Alnarp.
Norränga is situated on the fringe of the city of Lund, east of the existing district of Linero.The city planning office of Lund municipality has come up with a ?in-depth comprehensive plan? for the exploatation of the eastern area of Lund. The plan concerns an area of 1035 square kilometre which contains at least 1500 nya buildings, two schools, primaryschools, stores and bus station for local bus traffic and the new bus line - Lundalänken. The townplan is inspired from the historical Square block city with defined street system. The municipality has visions of what the green areas should consist of.
Aspekter på flyttkostnader, fastighetsbildning och fastighetstorlekar :
This master thesis has three purposes. The first purpose is to give a theoretical background of how to divide up forest estates and to study how the legal system for these matters works.
A literature study has been carried out to give the background and a theoretical model has been made for analysing the law cases. The first purpose also partly touched the decision process in dividing up forest estates from point of view of the law of land parcelling (FBL), point of view.
The second purpose is to examine effects of a change of production requirements in 3 cap.7 § FBL as regards dividing up forest estates of private forest owners.
Beslutsstöd för lagerhantering : Matematisk optimeringsmodell för godsplanering och simulering
Det är allt vanligare inom tredjepartslogistik att kunder hyr en yta för lagring. För den uthyrande parten, i detta fall Delta Terminal, är arean den begränsande faktorn för hur stor yta som kan hyras ut. Idag använ-der sig Delta Terminal av beslutsunderlag i form av lokalernas area och erfarenhet vart gods ska placeras och har inget hjälpmedel för att beräkna vart och hur mycket gods som kan allokeras för att använda så liten yta som möjligt. Studiens syfte har därför varit att ta fram ett faktabaserat hjälpmedel som kan användas som beslutsunderlag. För att uppnå syftet har en matematisk modell utvecklats för att optimera hur gods kan placeras till olika lokaler för att använda så liten area som möjligt och även kunna simulera förändringar.
Miljöstyrning i Riksbyggens ombyggnadsprocess med hjälp av Miljöbyggnad
How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses.
Introduktion av Open Source som arbetssätt
In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.
Ledarskap på låga nivåer inom sjuk- och äldrevården : Hur upplever medarbetarna sin ledares agerande och beteende?
I dagens samhälle möter vi ständigt ledares behov av att öka sin kompetens när det gäller att hantera kritiska situationer inom den offentliga sektorn. Bristande kompetens hos ledarna drabbar inte bara dem själva utan även medarbetarna. Många uttalar sig om att det bristfälliga ledarskapet i den offentliga sektorn ger upphov till rekryteringssvårigheter, hög sjukfrånvaro, ineffektivitet, kvalitetsproblem, resursbrist och brist på kompetens. Även forskningsartiklar visar att det är högre sjukfrånvaro pga. dåliga ledare och det illustreras dagligen i dagspress och nyhetsförmedlingar.I vår kultur saknar vi metoder att hantera problemet med dåligt ledarskap.
Är en schimpans bättre på att skapa avkastning än en professionell fondförvaltare? : En jämförande studie om historisk avkastning av förvaltade fonder och slumpmässigt genererade portföljer
Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.
Inmatning av matematiska uttryck i en digital miljö
Inom matematikämnet har e-bedömningar, aktiviteter där digitala tekniker används för att bedöma studenters kunskaper, inte utvecklats i samma takt som e-bedömningar inom andra områden. Detta beror sannolikt på det stora inslag av symboler och icke-standardiserade tecken som karakteriserar matematiskt språk och särskiljer det från traditionellt skriftspråk. Ett problem som har noterats i samband med e-bedömningar inom matematik är att inmatningen av matematiska uttryck i ett digitalt system i många fall varit långsam och svår att begripa. Den här rapporten syftar till att undersöka tre kategorier av inmatningsmetoder utifrån aspekterna snabbhet, korrekthet och upplevd lätthet för att på så sätt skapa en bild av vilken av teknikerna som lämpar sig bäst att implementera i en e-bedömningsapplikation riktat mot den svenska gymnasieskolan. För att uppnå syftet har jag granskat tre familjer av tekniker genom att låta gymnasieelever genomföra inmatningar av matematiska uttryck och analysera dessa inmatningar baserat på inmatningstid, korrekthet och upplevd lätthet.Resultaten visar på att det finns tydliga skillnader mellan de undersökta teknikerna med avseende på samtliga undersökta aspekter.
Matematik+andraspråkselever = matematiksvårigheter? : Varför och vad kan lärarna göra?
The purpose of my examination work was to show the need for support for students with another mother-tongue than Swedish, so that these students would be able to get through mathematics tuition better. To achieve this purpose, I chose to start from the perspective that presented itself at interviews with two class teachers and two mother-tongue supervisors. I also chose to use the qualitative research interview as study method, as I tried to understand those informing me in a thorough and in-depth way. In my study I have had a sociocultural perspective as starting point where the conceptions teaching, language and communication, support and individualizing are central for the development of knowledge. The questions for my study during this process were as follows: What difficulties, according to the teachers interviewed can occur for second language students in mathematics? What ways and methods of working do the teachers chosen give priority to, so that the second language students` results in mathematics will improve? The results from my interviews show that the difficulties with mathematics for second anguage students can be perceived as being dependent on a combination of reasons, where amongst other things language plays a central part.

Datorbaserad bedömning i språk forskningsläge, erfarenheter och implikationer
To support uniform and fair assessment of Swedish students? English language competences, mandatory National tests are provided both for secondary and upper secondary education. The current thesis may be seen as a contribution to the further development and validation of these tests, with regard to the likely introduction of computerized testing methods. The aim is to gain further knowledge from current research in the field, to study and elucidate international experiences of implementation, and to gather and analyze feedback from students and teachers. Based on my findings, some tentative conclusions will be drawn, and recommendations made concerning future developments.
Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer
Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.
Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data
To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.
Medielek och digital kompetens i en förskolekontext : Design för meningsskapande
The aim of this thesis is to make a contribution to the field of design oriented theory, regarding young children and their way to digital competence. My research question is: How can a preschool with a certain pedagogical ICT-design give the children affordances for media play and for developing a digital competence?The European Parliament points out digital literacy as one of the Key Competences for life long learning. A digital competence is built on basic ICT (Information and Communication technology) skills. Skills you can develop any time during life, weather you are young or old.
