In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.

Det ?vergripande syftet med studien ?r att unders?ka vilken tillg?ng patientf?retr?dare har till vetenskaplig kunskap och m?jligheten att bidra under vetenskaplig kunskapsproduktion, vilka resurser som kr?vs f?r patientdelaktighet och hur lekmannakunskap v?rderas inom l?kemedelsforskning. Studiens fr?gest?llningar lyder: 1. Utifr?n patientf?retr?dares f?rst?else, vilken tillg?ng har de till vetenskaplig kunskap g?llande l?kemedelsforskning och hur p?verkar det m?jligheten att medverka vid vetenskaplig kunskapsproduktion? 2.

Syftet med den här uppsatsen är att undersöka hur den gamla kursplanen i historia från 1994 skiljer sig från den nya ämnesplanen i historia från 2011.Metoden för uppsatsen är en dokumentanalys av styrdokumenten: Kursplanen från 1994 och Ämnesplanen skriven 2011 samt att koppla detta till relevant historiedidaktisk litteratur.Resultatet är att ämnesplanen och kursplanens innehåll skiljer sig åt. Vi ser tendenser till att ämnesplanen är utformad mer specifikt i vad undervisningen ska innehålla, medan Kursplanen är mer övergripande.Slutsatsen är att vår undersökning är relevant då den visar på vilka förändringar verksamma lärare måste göra i sin undervisning, dessutom finns det en tydligare koppling mellan ämnesplanen och den didaktiska forskningen..

The purpose of this master?s thesis is to study resource allocation among district libraries within Stockholm?s City Library (SSB) on three different occasions ? 1996, 2001 and 2005 ? and to examine whether there exist any inconsistency between the state of the allocation of resources and what might be considered reasonable. During the course of the study, it became apparent that some measurements are more relevant than others when determining whether the allocation of resources is reasonably fair. The most relevant ratio is the share of net cost per capita in relation to population and the population?s composition of children, youngsters and persons with foreign background as a result of relevant political governing documents giving priority to these three groups.

In the beginning of the 19th century, Swedish was the only official language of Finland, and thus the dominating language in administration and higher education. However, during the latter part of the century, efforts were made to develop Finnish into a language which could be used in every part of society. In 1881, the medical society Suomalainen Lääkäriseura Duodecim was founded with the development of a medical terminology in Finnish as one of its main purposes. In 1885, a medical paper, Duodecim, and a medical dictionary were published. The aim of this study is to illuminate the vocabulary of the dictionary.

Abstract: Since the recession caught the market in fall 2008, multiple companies have suffered due to their former aggressive investment behavior. Huge goodwill piles have been collected ready to be doomed by the market. The aim of the study is to investigate equity analysts? consideration of goodwill in a recession market. An empirical study is conducted, based on interviews with ten Swedish equity analysts that follow companies with relevant goodwill status.

Sociala medier ?r en del av dagens ton?rskultur, d?r Instagram, Snapchat och TikTok ?r de popul?raste apparna bland barn och unga. Forskning visar att anv?ndandet av filter p? sociala medier genererar m?jligheter att (om)f?rhandla sin identitet samt att anv?ndandet kan leda till att unga utvecklar orealistiska kroppsideal. F?r att f? en ?verblick ?ver f?ltet g?rs en strukturerad forsknings?versikt.

Sysselsättningen i den svenska landsbygden har minskat avsevärt sedan 1900-talets början. Den senaste tidens ökning av importmat tvingar mjölk- och köttproducenter att hitta andra verksamhetsområden att tjäna pengar på. I takt med samhällsutvecklingen har kraven ökat för bland annat närproducerade livsmedel. Landsbygdsföretagarna i Norrbotten är duktiga jordbrukare men har generellt begränsade kunskaper hur företag ska drivas. Lantbrukarnas Riksförbund startade för tre år sedan ett projekt i syfte att hjälpa jordbrukarna bli bättre företagare.

Bakgrund D?lig munh?lsa kan leda till b?de lokala infektioner och allvarliga sjukdomar s?som stroke och annan hj?rt-k?rlsjukdom. Tandborstning prioriteras ofta bort i v?rdmilj?er och det ?r sjuksk?terskans ansvar att v?rna om f?rebyggande ?tg?rder. Teorin om Missed Nursing Care fokuserar p? orsaken till uteblivna omv?rdnads?tg?rder.

Bakgrund: H?lso-och sjukv?rden ?r h?rt belastade verksamheter med otillr?ckliga personalresurser vilket kan f? konsekvenser f?r sjuksk?terske- och l?karstudenters m?jlighet att tr?nas i kliniska f?rdigheter och uppn? sina l?randem?l under den verksamhetsf?rlagda utbildningen (VFU). Genom att anv?nda Personcentrerade Virtuella Patientfall (PVP) i undervisningen ges studenter m?jlighet att tr?na p? sina kommunikativa och kliniska f?rdigheter i en trygg milj? utifr?n deras olika f?ruts?ttningar, men mer kunskap om studenters upplevelser av detta nya pedagogiska verktyg beh?vs. Syfte: Syftet ?r att beskriva studenters upplevelser av PVP och dess anv?ndbarhet i l?randet av kliniska f?rdigheter. Metod: En kvalitativ studie med induktiv ansats anv?ndes. En fokusgruppintervju med fem deltagare utf?rdes och materialet analyserades utifr?n tematisk inneh?llsanalys. Resultat: Tv? huvudteman och sex underteman identifierades.

Nyckelord: DBS, cervikal dystoni, personperspektiv, livssituation, kvalitativ och Roys Adaptionsmodell. Bakgrund: Dystoni ?r en sjukdom som drabbar r?relseorganen. Sjukdomen medf?r ih?llande muskelkontraktioner som leder till f?rvriden kroppsh?llning. Incidensen ?r 1,18/100.000/ ?r, vilket inneb?r att det ?r en relativt ovanlig sjukdom.

The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

This study investigates the value relevance of goodwill impairments for equity investors in Swedish listed companies. We provide insight on whether goodwill impairments are value relevant before as well as after the implementation of IFRS 3 and IAS 36. We express market value of equity as a function of book value of equity; net income excluding goodwill impairments and goodwill impairments, using the Ohlson valuation model and Hellström's price regression. Our findings suggest that goodwill impairments are statistically value relevant for equity investors. Prior to the implementation of IFRS 3 and IAS 36, our findings imply that equity investors respond negatively to goodwill impairments.

In query expansion (QE) terms are added to an initial query in order to improve retrieval effectiveness. In this thesis we use QE in the sense that a reformulation of the query is done by deleting the terms in the initial query and instead replacing them with terms from the documents retrieved in the initial run. The aim of this thesis is to, in a experimental full text invironment, study and compare the retrieval result of two different query expansion strategies in relation to each other. The following questions are addressed by the study: How do the two strategies perform in relation to each other regarding recall? What may be causing the result? Are the two strategies retrieving the same relevant documents? Two strategies are designed to simulate a searcher using automatic query expansion (AQE) either with or without relevance feedback.
