Föräldrars upplevelser av att vårda sitt nyfödda barn på Neonatal Intensivvårdsavdelning - En litteraturstudie.

Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.

Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät

In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

Breast cancer stem cells : evidence and contradictory views

This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.

Ett nytt pedagogiskt material! : 4DFrame, hur kan man arbeta praktiskt med det?

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.

Avrundar företag sina resultat - En studie av Cosmetic Earnings Management i Sverige

The aim of this thesis is to examine the occurrence of Cosmetic Earnings Management (CEM) among Swedish companies. CEM refers to the small upward rounding of reported net income to reach cognitive reference points. Important cognitive reference points are multiples of ten (N*10^x) of reported net income and rounding towards these has been documented in other markets around the world over the last 20 years. The occurrence of CEM on the Swedish market is studied using digital analysis, frequency testing and Benford's law. Firstly, reported net income of publicly traded companies between 1996 and 2010 is examined.

Magnesiumintagets betydelse för blodtryck och magnesiumkoncentrationen i stickprov av urin, träck och blodplasma hos häst

The purpose of this trial was to evaluate the possibility to use sampling of faeces, urine and plasma, and measurements of blood pressure as methods of discovering hypomagnesemia in horses, as well as the application handiness of these methods. The most commonly used method of checking the magnesium status of a horse is to analyze samples of serum or plasma. The trial was of a switch-back design, in which the horses were used as their own controls. The animal material was five Swedish warm blooded trotters between six to ten years old, and weighing between 485-620 kg. The trial consisted of three periods that were two months each.

The Last Track : En slutstation och en skriftlig reflektion

Fokus för den här C-uppsatsen är arbetsmetod och arbetsprocess i den estetiska lärprocessen ur ett ?målrelationellt? perspektiv i vilket målet för elevarbetet ses som en produktion av estetisk praktik och reflektion och där bildspråket fungerar som en pedagogisk funktion vilket bidrar till en förskjutning av synen på hur man lär sig genom relationella möten.Undersökningen utgår från ett ämnesintegrerat filmprojekt mellan samhällskunskap och rörlig bild som jag gjorde med elever på en gymnasieskola 2008. Jag har undersökt detta genom att låta före detta elever komma till tals och i intervjuer har de sex år efter avslutade studier, med hjälp av foto- och filmelicitering, berättat om vad de minns av arbetsmetod och arbetsprocess i filmprojektet. Bakgrunden till studiens frågeställning är en handledande arbetsmetod i rörlig bild, och funderingar kring vad den gör med lärande skolarbete i ämnesintegrerade projekt. Är estetisk lärprocessen i rörlig bild ett flummigt estetisk nonsens, något roligt att göra i vila från andra ämnen, eller hjälper detta elevers lärande framåt samtidigt som de har roligt i sitt skolarbete? Syftet med min studie är att belysa hur det relationella synliggörs i en estetisk lärprocess och jag vill härigenom bidra med kunskap om detta.I resultatet av undersökningen visar det sig att de före detta eleverna upplevt att den handledande arbetsmetod de fick tillgång till i arbetet med rörlig bildutvecklat deras färdigheter att reflektera över sina kunskaper, kritiskt granska, värdera och lösa problem i lärandet.

Sound and Play

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Fysisk aktivitet som fallprevention i särskilt boende - en litteraturstudie

Our population are ageing. As this happens more people will be in need of long term care facilities. We now know that some elderly people with certain background factors are more likely to be injured or sick. One of the four biggest background factors is fall propensity. Most of the reported falls come from long term care facilities, approximately 60 % of the care takers in long term care facilities fall one time or more each year.

ATT STIMULERA TILL LÄSLUST Hur bibliotekarier kan arbeta för att läsovilliga barn och ungdomar ska kunna känna läslust!

The purpose of this Master's thesis is to make suggestions as to how librarians can promote young reluctant readers to help them find the joy of reading. We want to show how the comprehension of these children and adolescents can be translated into action in the librarians work with reading promotion.Our main questions are:? What attitudes do the librarians find that children and adolescents, ages 9-15 with reluctance to read, have towards reading?? What do public- and school librarians do to stimulate children and adolescents, ages 9-15 that are reluctant to read, to feel the joy of reading?? What role or which roles can the public- and school librarians have in the work of reading promotion, targeting children and adolescents with a reluctance to read?We have used Beers's theories about reluctant readers and reading promotion, Chambers's model and theory ?Reading Circle? and his theories about conditions that promote a ?good reading environment?. We have also used Smidt's theories about the librarian's different roles in the work of supplying literature.The method we have used is qualitative and based on literature and interviews with 7 children- and school librarians that all of whom work or have worked with reading promotion for children and adolescents in the ages between 9-15, that are reluctant to read.Our results show that in order to gain understanding about the attitudes towards, and relationship to reading, our targeted group have, the librarian has to be aware of the inner conditions that these children and adolescents have. These inner conditions are going to affect the work and the result of the reading promotion activity.

H?llbarhetsrapportering i svenska industrif?retag

Sustainability and the role of companies in terms of emissions and environmental impact has become increasingly more relevant. In 2014, the EU decided to introduce the NFRD, a directive that makes it mandatory for companies that meet the requirements to report on sustainability. This thesis aims to examine how four large Swedish industrial companies report about sustainability in connection with the introduction of NFRD, looking at the years 2015 (2014), 2017 and 2022 from an environmental viewpoint. Furthermore, the study also intends to investigate how the companies write about their sustainability work, as actual achievements or what they have ambitions to do in the future. In order to carry out the study, a content analysis with elements of both qualitative and quantitative features has been used called the CONI method.

Den icke-monetära nyttans betydelse för prisbildningen på skogsfastigheter : en intervjuundersökning

The market value of forest properties can be assumed to consist of two components, a monetary factor and a non-monetary factor. The objective of this examination paper is to study the impact of non-monetary factors on the values of forest properties in Sweden. This study is based on a population of buyers of forest properties in the southern of Sweden. The results are based on interviews with 54 buyers. Of the purchases were 37 % new purchases.

Utvärdering av prototypen för ett kollaboratorium inom biblioteks- och informationsvetenskap

This study is a formative evaluation of a prototypecollaboratory for sharing data collection instruments inlibrary and information science (LIS). The aims were to findout: how the study participants, five hospital librarians,experienced the interaction with the prototype while workingwith predetermined tasks; and their views on the differentfunctions of the prototype collaboratory.Methods used for data collection was as a survey; followedby a think-aloud session where the participant verbalisedhis/her thoughts during the interaction with the prototype;and finally a semistructured interview. The survey wasanalysed with a frequency distribution, while the data fromthe other methods were analysed qualitatively by extractingthemes from the transcribed sessions.The results show that although the librarians expresseddifferent problems while working with the interface, mainlyrelated to the language in the prototype collaboratory anddifficulties with the page for applying metadata, all of themwere confident in being able to learn the system after using itfor a while. The librarians had a positive attitude towardssharing data collection instruments as well as comments inthe prototype collaboratory. At the same time, they wereaware that students and researchers might have differentabilities or incentives to work and share information.

Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå

Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.

Sexualitet efter en hjärtinfarkt- Behovet av information

Sexuality contains more than just reproduction and is an important part of quality of life. Chronic disease can lead to sexual dysfunction for both males and females. The nurse plays an important role in informing and teaching. Throughout dialogue and observations the nurse can detect possible problems, document and then take measures. The study was performed as information retrieval of literature where the cause was to highlight sexuality for patients that have experienced a myocardial infarction.
