Patienters upplevelse av omvårdnad efter suicidförsök : En litteraturöversikt

INTRODUCTION: Attempted suicide is very common. Those who arrive to a hospital by reason of attempted suicide need a nurse with qualifications in the care of suicidal patients. OBJECTIVE: The aim of this study was to compile and elucidate research which describes how patients in care for their attempted suicide experience the care that is received. METHOD: A literature review was chosen for this study. Scientific articles sought in the database CINAHL.

Kontrollerad vokabulär eller naturligt språk? En empirisk studie.

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.

Universell kunskapsorganisation: identifiering av ett framväxande forskningsområde genom citeringsanalys.

An ongoing discussion concerning the possibilities of universal classification based on phenomena rather than on research disciplines has been noticed. In order to discover if this was a limited discussion or the beginning of a major new field of research a study of citations was made using the database Web of Science. In addition, references of the works concerned were studied to find out where the ideas originated. The study of references shows that the ideas originate in a limited number of older published works, some of them well established in Information Science, some of them less generally known. The main ideas commonly used in Information Science are Ranganathan?s facet theories and the work of the Classification Research Group.

Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.

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.

Utveckling av ett verktyg för produktkataloggenerering

Produktkataloger publiceras och distribueras idag av många detaljhandelsföretag, stora somsmå. Dock har det påvisats att katalogproduktion kan vara både tids- och resurskrävande. Dettaexamensarbete har därför syftat till att finna en lösning på problemet genom att undersökabehov och förutsättningar och därpå utveckla ett verktyg som kan underlätta arbetet med attskapa produktkataloger. Målsättningen var att det resulterande verktyget per automatik skulleframställa en produktkatalog i PDF-format utifrån ett befintligt artikelregister.En förstudie visade att trots olikheter i befintliga produktkatalogers utformning finnsändå vissa gemensamma element såsom produktbild och pris. Detta faktum utnyttjades vidutvecklingsarbetet där det förutsattes att ett artikelregister, oavsett typ av datakälla, alltidinnehåller vissa informationselement som kan publiceras.

Bakomliggande faktorer till presbyacusis; en litteraturstudie av mindre kända faktorer

Background: More than half of the elderly (65-84 years) in Sweden have problems with hearing. In some studiesit?s discussed if age related hearing loss or presbyacusis is a part of natural aging or if it depends on underlyingfactors.The purpose of this literature study was to analyse scientific papers which illustrate correlations between lessknown underlying factors and presbyacusis, defined from psychoacoustic and/or neurofysiological tests.Material and method; Literature study where scientific papers, relevant to the purpose of the study and thequestions at issue were found in the database PubMed.The result shows that cardiovascular disease, hormones, diet and drugs have an influence on presbyacusis. Thehealth condition of the individual and their lifestyle matters, likewise estrogen which according to the results of 2studies has a protective effect on hearing.Conclusion; The studies show that heart attack and high systolic blood pressure in women have a correlation topresbyacusis, but not in men, - the hormone estrogen, - some vitamins, antioxidants and diet have a protectiveeffect on hearing and studies show that smoking and alcohol have negative effects..

På personlig frekvens - En studie av svenska B2C-företags inställning till RFID inom lojalitetsprogram

Kundrelationerna i svenska B2C-företag är inte lika goda som de var för 60 år sedan och de är inte lika goda som företagen skulle önska att de var. Forskningsfrågan och syftet med uppsatsen var därför att förklara vad som påverkar svenska B2C-företags beslut att utnyttja Radio Frequency Identification (RFID) som identifieringsteknik för att personliggöra kundrelationer inom sina lojalitetsprogram. Studien utfördes som en fallstudie då vi undersökte hur två stora svenska B2C-företag, IKEA Family och ICA, arbetade med lojalitetsprogram, identifieringstekniker och hur de ställde sig till alternativa identifieringstekniker gestaltat genom RFID. Studien utfördes med deduktiv ansats genom inledande teoriinsamling och därefter genom intervjuer med en intervjuperson på vardera företag. De slutsatser som sedermera kunde dras var att tillräcklig kunskap saknas kring RFID och dess potential, att det är en ekonomisk fråga och en stor investering för företag som inte brukar vara först att ta till sig ny teknik som dessutom inte är standardiserad samt att det skulle kunna kränka kundernas integritet och därmed ha motsatt effekt till lojalitetsprogrammens syfte..

MÖJLIGHETERNA MED CLUSTERED COLUMNSTORE INDEXES & IN-MEMORY OLTP

Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.

Att sticka ett oroligt barn - sjuksköterskans möjligheter att lindra / To prick children : Nurses' possibilities to relieve distress

Background: Children frequently exhibit high levels of distress while undergoing routine blood sampling or injections. If the child is not treated with appropriate care, the feelings of distress may increase over time and result in needle-phobia. Objective: The purpose of this study was to describe nurses´ possibilities to relieve distress in children undergoing needle sticks. Method: A systematic literature review was conducted through database search and screening of reference lists. Ten research articles with a quantitative approach were included, coded for quality and then analyzed.

Cisterciensklostrens odlingar i Sverige under medeltiden

The aim of this paperisto find out which plants the Cistercian monks might have cultivated in Sweden during the Middle Ages and which types of plants it would have been practical to grow inside or outside of the Cistercian monastery precinct. Archaeologicaland archaeobotanical studies have been consulted to find out which plants were available in Sweden during the Middle Ages. Examples, mainly from Scandinavia, but also from the continent, are used to show that the monasteries were large institutionsthat had to feed a large number of people and that there would not have been enough space to cultivate everything needed within the monastery precinct.Secondary sources have in the main been used to gather this information, except in the case of the Swedish monastery of Nydala where F-Topo, a database developed by the County Museum of Jönköping,has been used to analyse the amount of land and the types of properties owned by the monastery.The conclusion is that for practical reasons the monks would have cultivated plants that needed to be close at hand, that were rare or delicate, that could not be stored for long periods and that were used in small quantities within the monastery precinct. This would include medicinal plants, herbs for cooking and some vegetables like lettuce, spinach,and similar,that do not keep well. Most other items, grains, cabbages, root vegetables, peas and beans could equally well be cultivated outside the walls.

Lagringsmätning för AD-information

Målet med detta projekt var att hjälpa IT-Mästaren att kunna fakturera sina kunder på ett smidigare sätt. Deras dåvarande lösning av kundernas dataanvändning var tidskrävande och ineffektivt, därför ville de automatisera systemet. Det nya systemet skulle användas för att administrera kundernas servrar med hjälp av ett grafiskt gränssnitt och sedan kontakta dem för att få fram olika värden för respektive kund som ska presenteras på IT-Mästarens hemsida. På så sätt skulle de kunna fakturera sina kunder på ett mer effektivt sätt och även få bättre överblick av kundernas användning. I och med utvecklingen utav detta system så fördjupande jag mig dels i egna kända områden men jag lärde mig också nya kunskaper. Det gällde inte enbart teknisk utveckling utan också undersökning av exempelvis hämtningen av alla data som skulle göras.

Är ni ett vanligt parti idag? : En studie om Sverigedemokraternas gestaltning i Aftonbladet och Expressen 2010 och 2012

The aim of this study was to determine to what degree the framing of the political party the Sweden Democrats had changed in swedish media, from 2010 in contrast to 2012. Particular interest was directed towards the framing of the party as a problem.This was done by studying the news articles during 12 weeks in 2010, and 12 weeks in 2012, in the newspapers Aftonbladet and Expressen. These particular newspapers were especially interesting to study since they have been outspokenly critical of the party. Both of the newspapers can be said to be among the most clearly critical towards the Sweden Democrats.I studied 256 published articles retrieved through the news database Newsline. Quantitative content analysis was used to determine patterns and tendencies.

The dynamics behind Consistency: Case study on NTT Group and Deutsche Telecom

The main aim of this thesis is to investigate the implications and dynamics behind consistency between individual resource allocation decisions and corporate strategy concept. The telecom industry, a high-velocity environment going through an extensive deregulation process, is put under the magnifying glass. Japanese telecom giant NTT Group is compared to its German counterpart Deutsche Telekom. Potential antecedent factors in the strategic decision-making process to consistency are studied. It is also examined whether there is a direct interplay between consistency and economic performance.
