När det sociala tar överhanden ? en explorativ studie om Facebookberoende bland gymnasieungdomar.
Facebook. Ett fenomen som på relativt kort tid fått en allt större inverkan påmänniskors liv. Men vad händer när det tar överhanden? När vad som var tänktsom en social plattform för att hålla kontakt med vänner blir till ett beroende? Denhär explorativa studien utforskar Facebook-beroende bland vad som enligt tidigareforskning anses vara en riskgrupp: gymnasieungdomar. Hur stor andel avgymnasieungdomarna skulle kunna vara beroende av Facebook, och finns detaspekter av deras fritidsliv, umgängespreferenser, hälsa och Facebook-användandesom verkar kunna bidra till ett beroende? Med hjälp av en kvantitativ ansats dären översatt version av den norska Bergen Facebook Addiction Scale har delats ut ienkätform undersöks Facebook och dess inverkan på gymnasieungdomar på enskola i Göteborgsområdet, och resultaten visar att en betydande andel avgymnasieungdomarna skulle kunna vara beroende av Facebook.

Wild boar paradise : What makes the Swedish wild boar reproduce more or less successfully?
Due to the growing wild boar (Sus scrofa L.) population in Sweden there has been an increase in wild boar related traffic accidents, damage on cropland, and conflicts regarding the management of the wild boar. Knowing what makes the wild boar reproduce and survive more or less successfully in different geographic areas is an important part of managing the population. According to previous studies the wild boars rate of increase varies from county
to county. The aim of this study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this
variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase.

interesting. Wood chips is very popular, but also straw from grain production is on the
table. Lunds Energi AB project a combined power and heating plant in Örtofta out of
Lund. Wood chips is meant to be the main energy source, complemented by straw.
In this thesis the transportation of straw for fuel is studied.
Patent och företags storlek - finns det en tröskel till inträde?
Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..

Revisor idag, redovisningskonsult imorgon : Har revisionen spelat ut sin roll i mindre företag?
In 2010 mandatory audit was revoked for small and medium sized companies in Sweden. At the same time the authorization for accounting consultants was established with the aim of raising the knowledge and status of the profession. Even though The Swedish Companies Registration Office has discovered more errors in the accounting after the mandatory audit was eliminated, it especially concerns those companies who does not have neither an auditor or an accounting consultant. One of the reasons often mentioned to be audited is the auditors role when it comes to lending decisions. Our empirical studie show that the auditors most important function, being unbiased, is not what is of greatest importance for the credit institutions.Instead it was professional skills, and for small and medium enterprises (SME) it was consulting they requested the most.
Gr?n Gentrifiering p? Hisingen: En spatial och kvantitativ analys av gentrifieringsvariabler och parker 2015-2023
This study examines whether a spatial relationship exists between blue-green infrastructure and indicators of gentrification in Hisingen, Gothenburg, during the period 2015?2023. Using a GIS-based approach, sociodemographic changes across 83 demographic statistical areas (DeSO) were analysed in relation to six parks established or significantly developed during the study period. Changes in mean income, educational attainment, share of residents with foreign background, and mean age were combined into a gentrification index, which was then tested against distance to the nearest park through linear regression analysis.The results show that socioeconomic changes consistent with gentrification occurred across parts of Hisingen during the period, with the highest index values concentrated in the central and south-eastern parts of the district. However, these changes were geographically selective rather than district-wide.
The Countryside dream : amenity Migration and the new transit-oriented communities
This is a final thesis in landscape planning, at the Swedish University of Agricultural Sciences (SLU). The study examines the current phenomenon of amenity migration and the international discourse applicability of the a "Countryside dream" in a small neighborhood in Käglinge, part of the transit-oriented community Oxie just outside of Malmö in the southern part of Sweden.
The critical starting point of the study is the how many planners idealize the dense city with its positive proximity qualities. However, since the late 1900s, many people have instead started to idealize living in more rural or naturally appealing landscapes, often just outside a bigger city, with good transit possibilities (both by car and bus as well as by train).
The phenomenon of amenity migration ? the migration to a new, more appealing everyday environment considered to have more amenities, is very relevant today since many smaller communities are becoming more transit-oriented, allowing the inmigrants to work in some bigger, dense town while living in a small-scale, less dense semi-rural community.
More dense transit-oriented communities are however also an ideal to planners in Sweden, but to what extent can Käglinge in Oxie ? a neither rural nor urban community - fulfill a possible countryside dream, and what role does the train station have in the in-migrants everyday life?
The study has a theoretical starting point in literature regarding amenity migration, countryside ideals, representations of the countryside and the possible migrants themselves, giving a broad perspective on these related issues. The case study of Käglinge in Oxie is then presented, including interviews with Käglinges in-migrants.
Riskkapitalbolags inverkan på risk för finansiell kris i portföljbolag: En studie av 53 transaktioner i tillverkningsindustrin
The aim of this small thesis is to investigate if the probability of business failure is higher at the time of divestment than at the time of acquisition for portfolio companies that have been subject to private equity ownership. The background for this thesis is the widespread critique aimed at private equity firms, claiming that they increase the risk in their portfolio companies. We have performed a study of 53 buyout transactions, involving Swedish manufacturing companies, covering a time span of 13 years, from 1995 to 2007. We find evidence of an increased risk of business failure for the portfolio companies with a short forecasting horizon (within one year). The absolute increase in the sample is however small.
Möjliga alternativ för att ersätta direktverkande el i flerbostadshus
I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.
Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :
According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.
Kan förändringar i bottenfaunan påvisas två år efter en bäckrestaurering?
The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.

Förslag till rekommenderade referensvärden för Falls Efficacy Scale (Swedish version) för friska äldre
Syftet med studien var att undersöka fallrelaterad self-efficacy mätt med Falls Efficacy Scale (Swedish version) (FES(S)) samt att beräkna rekommenderade referensvärden för totalpoängen på FES(S) hos friska äldre män och kvinnor indelade i åldersgrupperna 65-75 år samt > 75 år. Vidare syftade studien till att undersöka om det fanns några skillnader i resultatet mellan åldersgrupperna samt mellan män och kvinnor.Undersökningsgruppen bestod av totalt 70 individer över 65 års ålder, varav 45 var kvinnor och 25 var män. Testdeltagarna kontaktades via PRO i Uppsala. Även vänner och bekanta till författarna deltog i studien. Testdeltagarnas fallrelaterade self-efficacy undersöktes med hjälp av instrumentet FES(S), där testdeltagarna fick skatta hur säkra de känner sig på att utföra 13 olika vardagsaktiviteter utan att falla, maximal poäng 130.Resultatet visade att det rekommenderade referensvärdet för totalpoängen på FES(S) blev 124 poäng för kvinnor i åldern 65-75 år och 126 poäng för män i samma ålder.
