Bibliotekarien som distansarbetare? : förutsättningar för bibliotekarien att utföra sina funktioner på distans
We studied how librarians would adapt to telework, the performance of job responsibilitiesfrom home. We found'that all duties could be accomplished. but to varied extents.Computerbased searches, interlibrary loans, acquisitions, indexing and telephone referenceservices are the duties most likely to adapt to telework whereas cataloguing andclassification probably are best performed in the ordinary workplace.Most duties would demand access to technical means of assistance when performed fromhome. Connections to the library's local network, directly or via modem, are requiredbecause it is unrealistic to expect librarians to telework with fewer tools than theyordinarily have available. Although librarians generally believe that teleworking will nothave a large irnpact on the operation of the library, most would like to telework.Whether teleworking is a viable strategy depends on the characteristics of the duties, thelibrarian's desire to telework, but also on the size of the library, the size of its staff, thelibrary's activities, and how work is distributed between librarians..
Sökmotoroptimering : Metoder för att förbättra sin placering i Googles sökresultat
This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.
Weblogindex: En studie av weblogindex utifrån Lancasters processmodell över traditionell indexering.
Many new electronic publication systems have arisen in the past few years, one of them is the weblog. In 1999 there were 23 weblogs, today there are millions thus a need for organisation has appeared, both special metadata and subject indexes have been invented and created. Due to the large amount of the latter we have in this thesis decided to concentrate on those close by the Scandinavian weblogindexes. A more international perspective would however have been possible, as very little is written on the topic. We have looked at these selected weblogindexes, trying to determinate whether they agree with F.
Slumpens betydelse på aktie- respektive spelmarknaden
Många berättar om de ekonomiska vinster de gjort på börsen under senaste åren, och hur lätt pengarna rullat in på deras konton. Med en liten inblick i finansmarknaden och genom att titta på A-ekonomi då och då så blir i stort sett alla aktieaffärer lyckade. Vi hör dock sällan någon berätta om folks dåliga aktieaffärer. Börsen verkar med andra ord vara en guldgruva för dem som investerar där. Med hjälp av dyra aktierekommendationer kan man göra ännu större vinster enligt en rad olika fondkommissionär.
Vardagliga icke-produktiva motoriska beteenden : förekomst och korrelation med sensation seeking
In everyday life we perform motor behaviours that have no apparent instrumental function. Are these correlated to sensation seeking and do they differ depending on what situations we are in? University students in Örebro (N=108), participated in the study. The participants were asked to fill out a double questionnaire containing the sensation seeking scale and another one for measuring non-productive motor behaviours. The non-productive motor behaviours were not correlated to the sensation seeking scale.
Svenska Mässan : en reflektion över Johan Helmich Romans liv och hur det svenska språket kommer till uttryck i Svenska Mässan
An analysis in the work of Martin Kellermans comic ?Rocky? of the interaction between the male and female characters and of how each of their gender are portrayed. We are going to find out if it is probable for young adults to be affected by any eventual gender-stereotypes that we can find in ?Rocky? or if ?Rocky? consolidates a stereotypical image of men and women that young adults might have developed through different media. We conduct this analys by first reading through random seleceted ?Rocky? books and present some of the comic strips where men and women interact with each other or discuss the opposite sex..
Kunskapsteori och kunskapsorganisation: En diskursanalys
This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.
Utvärdering av produktionsrapporterad volym för contorta
The background to this study is that the forest company, Holmen, has found large discrepancies between harvested volume and the measured volume at the industry. Factors like bark features, breakage, double tops, bends and stem damages was noted, and all stems were measured manually. Hypothesis testing with the method "random in pairs" were used to examine whether the harvester measured values significantly differed from the manually measured.
The result of a properly calibrated harvester shows in average underestimation of the volume with Skogforsk Pine as a bark function. This means that the harvester isn´t the reason why the volume measured in the industry is lower, the fault is elsewhere. The study also indicates a need for a unique bark function for logepole pine..

Optimerad bildsökning ? Bör vissa egenskaper prioriteras vid sökning efter en viss kategori av bilder?
As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..
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.
Produkthype: En fallstudie (En kvalitativ undersökning om vad som ligger bakom en produkthype)
To identify the underlying forces behind a product hype is difficult and the findings often seem random and unclear. To create a better understanding behind the affecting mechanisms would consequently be a valuable addition to the surrounding research area. The purpose of this paper is to understand if there exist common denominators between different product hypes and in such a case, which these are and how they function. By conducting a case-study on four products which have enjoyed immense sale success on the Swedish market, the possible presence of structural resemblance will be analyzed. From the study we can conclude common denominators such as the presence of an underlying trend and an overbalance of indirect decision basis do exist.
Vem eller vad sätter priset? : En kartläggning av inköpsmarknaderna för tre metaller (Krom, Molybden, Vanadin)
Detta arbete utförs efter en förfrågan från Uddeholm Tooling om att försöka kartlägga riskerna på inköpsmarknaden för metallerna krom, molybden och vanadin. Då detta anses vara mycket svårt föreslås här istället en kartläggning av marknaden för respektive metall, detta för att ge en bild av hur marknaden ser ut och vilka aktörer som finns.Frågorna som behandlas är var bryts, förädlas, konsumeras respektive metall? Hur varierar priserna, beskrivs priserna bäst med en random walk eller med en mean reverting stokastisk process.Det visar sig relativt snart att det är mycket problematiskt att inhämta relevant data. Speciellt då dessa metaller inte handlas öppet utan där kontrakten mellan köpare och säljare är konfidentiella. Priserna som rapporteras baseras på månatliga intervjuer med köpare, säljare och traders som utförs av branschmagasin.
Prislisteoptimering för ett sågverk - Jarlträ AB :
This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The work was an assignment from Jarlträ AB which is a privately owned sawmill located in southern Småland. The aim of the work was to investigate the economical result of different pricelists and how to adjust different parameters such as length correction to give an optimal result.
The pricelists was examined through a computer program (SilviA). The pricelists was made in the program and after that a simulation was preformed with a selection of random sampled trees gathered from the area nearby the sawmill.
Hållfasthetssortering av plankor med hjälp av röntgendata
The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.
