Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
Gestaltningsfloran : en brygga mellan hortikultur och biotopgestaltning
Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs
consist of colourful flowers, exotic species and cultivars with double flowers.
Diversifiering i lantbruksföretag : en litteraturstudie om hur utvecklingsprocessen ser ut i lantbruksbaserade företag som utvecklar nya verksamhetsgrenar
Today´s debate in farming is being focused on tourism, outdoor life and hobbies in the rural areas. This is of interest also for the general public as a way of counteracting the depopulation of the rural areas. Within the last years, the farming has become more technically advanced and hence efficient. This has led to increased production volumes and wider selection of products with lower margins for the farmer as a consequence. When the profitability is reduced, the farmer is faced with the choice of either increasing efficiency or diversification of the business.
Elevers relation till matematik : En jämförelse mellan mellanstadielärare och högstadielärares syn på elevers relation till och lärande i matematik
ABSTRACTThe purpose of this essay is first to get a general idea about a group of working teachers thoughts of mathematics and the teaching in mathematics. I also would like to find out what they think affect pupils relationship to the subject. The surveys main purpose is to compare teachers in grade 4-6 and teachers in grade 7-9 view of what you as a teacher can do to further the learning in mathematics. I have done eight interviews. Four of them are with teachers in grade 4-6 and the other four interviews are with teachers in grade 7-9.Concerning the result of my examination it is difficult to come to a general conclusion.
Förstärkning av bro 17-803-1 : En jämförelse av förstärkningsmetoder
AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.
Kritikens kris: En diskursanalys av begreppet kritiskt tänkande inom förskollärarutbildningen
The following study is a discourse analysis of the concept of critical thinking within pre-school teacher education. It considers the following questions: how does the concept of critical thinking appear in policy documents, central to the pre-school teacher education, and which possible conceptions of critical thinking are conveyed by students and teachers active within the education. Additionally, the study seeks to discuss, as well as suggest a possible relation, between the findings of those two questions.
In reviewing the material (consisting of five semi-structured interviews with students and teachers, and of a selection of policy documents central to the education), I argue the existence of a sort of project within the education, which presents critical thinking as a higher value. At the same time, I argue that the concept is not defined or concretized. This project, however, as I suggest while drawing upon Foucault?s ideas of discourse and government, involves a rather high degree of control.
Är etiska fondinvesteringar försvarbara : vad kostar etik?
Recently, the selections of ethical funds are increased; at the same time investors with social and moral preferences have increased in the capital market. There are currently debates on whether ethical funds perform better or worse than funds without ethical criteria. This also involves a vivid discussion on whether investors know about the consequences of investing in ethical funds. Therefore, this study involves theories about the rationality and decision theory, in addition to what mainly control the investment decisions. The study also discusses portfolio theory since this is one of the underlying theories behind fund management and its development.The purpose of this study is to explain if ethical limitations in the selection of securities affect risk and return in the fund portfolio.

Strömsbergs köksträdgård - en historisk inventering
An era ended in 1920 when the Walloon ironworks village of Strömsberg closed. The Wallon people had lived on the spot for 300 years and influenced the region was a lot. The kitchengarden in Stromsberg was a gardencenter 1920-50.
The count´s good profits made him reinvest a lot of capital in the Wallon ironworks village to make it better and to construct forges, buildings and gardens. The kitchen garden´s history in Stromsberg started in 1660-70s, when Johan Vervier, built Strömsbergs first manor house.
Texturval hos svensklärare i relation till kursplanens ?centrala verk?
Denna uppsats handlar om texturval hos nio svensklärare i gymnasiet, samt deras tolkning av kursplanens formulering ?centrala verk?. Författaren till denna uppsats tar, förutom valet av tryckta skönlitterära texter, även upp multimodala texter och försöker undersöka vilka texttyper de intervjuade lärarna föredrar att använda i sin undervisning. Syftet är att försöka få en inblick i hur texturvalet hos gymnasielärare i svenska, i relation till kursplanens ?centrala verk?, kan gå till.Nio svensklärare som arbetar på gymnasiet har intervjuats via mail.
Mäktig eller osynlig : En diskursanalys ur genusperspektiv om hur maskulinitet tolkas och värderas i genusmedvetna texter och i museers utställningar
The survey aims to problematize masculinity in the exhibitions of the museum. In what way is masculinity interpreted and valued in exhibitions? What is the attitude towards masculinity in gender oriented museological texts? This study investigates in which way masculinity is written about ? how interpretations of masculinity emerge in the texts and what consequences this may have.The survey is based on the method of discourse analysis and the material is processed from a gender perspective. The source material consists of museological texts dealing with the topic of gender and museology, which also is the core material. A complement to this is a selection of exhibition catalogs from museums as well as reviews which are also based on art exhibitions. The main point of the source material consists of the museological texts.The survey highlights that the gender-conscious museological discourse understands, interpret and evaluate masculinity on a more or less given regulatory framework.
Folkbibliotekets uppdrag i teori och praktik. En diskursanalys kring formulerandet av folkbibliotekets uppdrag i ett urval biblioteksrelaterade tidskrifter under åren 1999-2000
The aim of this Masters thesis is to examine and analyse how the public librarys mission is interpreted and formulated in a selection of library related journals. The journals are both international scientific referee journals from the LIS field and journals with a closer connection to the practitioners within the public library field. The idea is that these journals can be seen as windows to an academic theoretic perspective on public libraries, as well as to the practitioners way of talking about the librarys mission. The study also aims to examine if there is a difference in the way that the librarys mission is interpreted and discussed among theorists and among practitioners within the field. The theoretical starting-point is Ernesto Laclaus and Chantal Mouffes discourse theory, and the method is text analytic.
?Wie waren die Tempi??: Ett försök till ett ?historiskt informerat? framförande av Ludwig van Beethovens op. 57, första satsen, i avseende på hans vilja rörande tempoaspekter
An attempt were made to record the 1st movement of Beethoven?s Op. 57, with the objective of performing it as close to Beethoven?s will as possible, in the tradition of the ?historically informed performance? movement.The result of evaluating source material rendered a list of the most relevant material for this study, and hopefully that might prove useful for other studies with similar objective concering HIP and composer-intention based ?autenticity?.However, Beethoven?s will was only vaguely captured in the limited source material accounted for in this study, rendering it moderate-to-small reliability. It?s probably possible to achieve a higher degree of goal achievement, given more time and through the utilization of music psychology to further extrapolate the detailed parameters of Beethoven?s presumed extramusical will.The recording made was not to my satisfaction and has strengthened my view that the interpreter should take council from the collected knowledge of scholarly sources but must ultimately remain free in whether and how to utilize that knowledge.Lastly, I?ve measured the bpm in the resulting recording with a error margin of ±0,02 s.
Varför ska vi spela handboll i skolan? : Lärares syn på handboll i grundskolan
AimThis qualitative study will provide an insight to different teachers view on handball in two elementary schools. Handball is a competitive sport and has been played for over 100 years in different contexts in Sweden. Are there qualities in the sport that belongs in the school´s non-competitive education? How do they justify this sport according to the governing documents Lgr-11 that gives a lot of room for interpretation by the teachers?How do teachers justify handball based on the curriculum?What kind of qualities do the teachers highlight with this sport in the education?Do teachers perceive any differences with the new curriculum?MethodThe method has a qualitative approach. The interviews in this study had a semi structure character.
Zoonosrisker i djurparker vid närkontakt mellan djur och besökare
Många djurparker erbjuder närkontakt med djur. Det kan innebära att besökarna tillåts klappa traditionella husdjur eller gå in till mer exotiska djur i anläggningar som försöker efterlikna djurens naturliga habitat och ge besökaren en inblick i djurens liv i frihet. Detta ökar risken för spridning av zoonoser, antingen via direktkontakt eller genom inandning av damm och aerosoler.
I det här kandidatarbetet har jag valt ut fyra sjukdomar som exempel på denna typ av smittspridning. Jag har inte tagit med sjukdomar där smittspridning sker endast av djur som uppvisar tydliga symtom eller beteendeförändringar, då jag förutsätter att de kommer under behandling istället för att förevisas publik.
De fyra zoonoser jag presenterar är ornitos, tuberkulos, salmonellos och EHEC/VTEC. Ornitos orsakas av Chlamydophila psittaci, en hos fåglar mycket vanlig bakterie som de utsöndrar via sekret från näshålan och via feces.
