Potatisen ur ett handelsperspektiv :
ABSTRACT
The potato has had an important role in the Swedish dietary customs for quite some
time. However, during the last forty years, consumption has decreased from 87
kg/year and person to 46 kg/year and person. Other products such as pasta, rice and
bulgur are competing with the potato. Many of the competitors have been developed
and refined while the potato has not changed much. The potato is still a bulk product
while competing products have been differentiated.
Stakeholders within the potato market has realized that something has to be done and
today there are a number of organizations and networks that all actively work to
preserve the Swedish agriculture and specifically the potato as a product.
The purpose with this essay is to examine how store managers in the Swedish grocery
stores view the handling of the potato in the store, the quality and packaging,
marketing and future consumption.
Specifikation för ett visualiseringsverktyg för consumption modes i aktiva databaser.
Syftet med denna rapport är att ta fram en specifikation för ett datorverktyg som visualiserar händelseupptäckt i aktiva databaser.Konventionella databashanteringssystem (DBHS) är passiva i den mening att data är skapad, hämtad, modifierad och raderad endast när en användare eller ett applikationsprogram explicit angivit detta. Många applikationer, såsom process control och power generation/distribution networks, kräver en snabb respons i kritiska situationer, och därför räcker inte ett passivt DBHS till. För dessa applikationer måste man kunna definiera villkor som övervakas av databasen. När dessa villkor sedan uppfylls utförs specificerade åtgärder/handlingar.Consumption modes är ett svårt och komplext område inom aktiva databaser. Som ett resultat av detta finns ett intresse i att använda visualisering för att lättare förstå de olika consumption modes som finns.En prototyp utformades för att fungera som underlag vid de intervjuer som senare genomfördes.
Skadliga nollflödespunkter i Fortum Värmes fjärrvärmenät i Stockholm : En analys av dess förekomst och effekter
When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.
Informationskrigföring : den nya teknikens hot
The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.
Small-worlds och rich-clubs bland bloggar : En nätverksanalys av den svenska bloggosfären under FRA-debatten 2008
Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.
Kvinnliga nätverk - ett sätt att göra skillnad? : En fallstudie på nätverket Q80 och dess mentor program
Sweden is known to be one of the world?s most equal countries. Nevertheless, out of Sweden?s 262 listed companies, only seven of them has a female president, which is equal to 3,4 percent. To counteract these numbers there are several possibilities. One arrangement that is highly controversial is affirmative actions. But there are other options, for instance more and more female networks are starting to rise and many of them also offers a mentoring program where the mentee gets the opportunity to learn from someone with more experience.The purpose of this study is to examine what difference the female network Q80, with focus on its mentoring program, is doing for the mentee. As an underlying purpose the study is also examining what visions and attitudes the management and the mentors is communicating within Q80. The focus is mainly on the visions of Q80, menas mentors and business exceeding mentorship. A survey has been carried out among mentees from three different seats of mentoring programs where they have answered 19 different questions regarding their time as a mentee. Furthermore interviews have taken place with the management of Q80 and two mentors. The results are analyzed based on theories about gender, women in management, leadership, mentoring program and organizational structure. The result shows that Q80i as a source of inspiration and a support for the category of "career women" with its core mission to strengthen the participation of individuals on a personal level more than to work to even out the gap in the Swedish labor market.

Acceptansgränsen för solceller i lågspänningsnät : Kan den ökas?
Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

STUDENTERS INFORMATIONSHORISONTER: Användning av Google och sociala nätverk i informationsökningsprocessen
The theses discuss information seeking with a focus on Google and social networks. Students attending the librarian program in Lund have been examined by means of two methods; diaries and information horizons, where they had to solve a specific assignment. The information horizon as a method contributes to getting a structural perspective on the information search process instead of viewing information search as a procedure. Information horizons use social network analysis.The aim of the theses is to investigate the importance of the social network in information search, with a particular focus on Google as a search tool. Our hypothesis is that Google acts as a compensator to the social network when the students search for information and in the educational program.The research indicates that there is no direct correlation between usage of the social network and usage of Google.
Mobilannonsering: Hur ett värdenätverk formas kring en ny mediekanal
Mobile telecom and the Internet are converging, which opens new possibilities for market actors to create business through the mobile handset. At the same time market experts are predicting that mobile operator?s existing dominance in the telecom market will in the future decline as new technology such as VoIP and services will erode the operator?s traditional revenue model. This implies that mobile operators will need to rethink their dominant business logic to create new value for their customers. Mobile operators are aiming to expand their existing revenue model through advertising in the mobile handset and are searching to create new business models that evolve advertising sales.
I medborgarnas tjänst?:En studie om avregleringens effekter på ansvarsfördelningen mellan offentliga och privata aktörer inom tre samhällsviktiga serviceområden i samband med orkanen Gudrun
The essay's aim is to explain how responsibility distribution between private and public bodies, primarily within three important service areas, can be visualised in light of the fact that they have experienced different forms of readjustment. We have chosen to study this by looking at the restoration work taking place after the hurricane Gudrun swept across southern Sweden on January 8-9, 2005; and we have chosen to concentrate on the service areas of electricity- and telephone supply, and public transport. The responsibility distribution has been depicted by carrying out qualitative interviews with employees within both private and public bodies included in the restoration work. The conclusion produced is that there were obscurities in the formal responsibility distribution between private and public actors taking place in conjunction with the hurricane restoration work.In a deeper analysis, the result can be explained by a ?several hands? problem arising since the number of actors has increased as the public sphere has adopted leadership forms influenced by the private business sector.
"Man vill ju se bra ut" : En kvalitativ studie om ungdomars syn på sociala medier
This thesis examines young people's thoughts about their presence on social media. With asocial constructive approach the study focused on how young people think and act on socialmedia in relation to constructions of gender and normality. The analysis is based on fourgroup interviews with 13-year old boys and girls. The theoretical approach is based partly onsocial constructionism where discourses and ideas of normality are identified and analyzed.Erving Goffman's theory of social interaction was central to illustrate how young peoplepresents themselves based on the prevailing discourses. It is clear that they adjust theirrepresentations of themselves depending on the context.
