Personalekonomi i teori och praktik

Given a considerable increase in knowledge-based companies, the interest for measuring and valuing intangible assets, particularly human capital, has increased accordingly. Human capital has climbed the management research agenda as human assets make substantial contribution to the value creation in knowledge-based companies. Neither internal nor external financial statements reflect the value of an organization?s human assets. Against this backdrop, we find it interesting to explore how counting and controlling for human capital is devised.

Utveckling av ett hjälpmedel för träning och utvärdering av förare av tunga fordon

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

Konsumentreklam som skapar framtidsutsikter - En kvantitativ studie om hur ökad annonsansträngning i konsumentreklam skapar bättre framtidsutsikter för annonsörens anställda

The purpose of this essay is to investigate how consumer advertising has an effect on other groups than the intended, the so-called extended audience of advertising. Previous research shows that consumer advertising can influence investors and employees of a company as well as affect the attractiveness of a company as a potential employer. In addition, research shows that more perceived cognitive effort in advertising results in positive signaling effects for consumers. This study aims to further build on these concepts in order to gain additional understanding of how consumer advertising can influence extended audiences. More specifically, it examines if more (versus less) effort in advertising can improve the future prospects on the labor market for an employee of the advertising company, by looking at recruitment consultants as an extended audience.

Finns det någon cross-overeffekt mellan statisk och dynamisk uthållighetsträning av bålmuskulaturen, och hur påverkar de olika träningsformerna resultatet på ett bålstabilitetstest?: En studie med single subject experimental design

Bakgrund: Bålträning kan användas vid prevention, behandling samt för att öka prestationsförmåga. Vilken typ av bålträning som är lämpligast för de olika ändamålen är dock fortfarande oklart, vilket till viss del beror på brist på tydliga definitioner inom området. Mot bakgrund av specificitetsprincipen inom träningslära och bålmuskulaturens olika indelningar och dess muskelfysiologi, vill författarna undersöka om en cross-overeffekt kan uppnås mellan två olika typer av uthållighetsträning, liksom träningens effekter på bålstabilitet. Syfte: Syftet var att beskriva observerade och mätbara effekter av dynamisk bålträning på statisk uthållighet i bålmuskulaturen, och omvänt, samt de observerade och mätbara effekterna av de respektive träningsformerna på resultatet av ett bålstabilitetstest. Metod: Studiedesignen var single subject experimental design (SSED).

Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala

The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

Identitetspresentation på Instagram : En studie i användares upplevelser och attityder till sin identitetspresentation på Instagram

In recent years, the internet has exploded of images. Not at least in the popular photo-sharing network Instagram as one of the fastest growing social network for the moment. Millions of people around the world share pictures and expose themself for friends and family. We were therefore interested in which experiences and attitudes users have towards their identities in relation to their self-image and self-presentation on Instagram. Furthermore, whether they in general have a primary interest in using Instagram as a tool to experiment with images to present their identity on Instagram, in which way they approach their Instagram follower?s expectations on how they present themselves on Instagram and if they are aware of any strategies in their self-presentation on Instagram.The result of this study is the fact that our respondents thinks that they do not intend to have a primary interest in experimenting with images on Instagram to present their identitiy, it is rather something that comes naturally in how they present themselves on Instagram.

Cassava as an additive in biomass fuel pellet production :

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

Den populärkulturella konstvärldens etablering som en social organisation där konstnärlig verksamhet är möjlig undersöks..

Vi tar tempen på ert CO2-utsläpp! : en studie av hållbarhetsredovisningars användbarhet

The environment has become an important part in people´s lives, and in today´s society stakeholders demands have increased upon companies when it comes to sustainability reports. How these sustainability reports are designed depends on whom it?s for, laws and regulations, and the companies own norms and values. The purpose of sustainability reports is to measure, monitor and compare a company´s enviromental impact. It?s not only about integrating economics, but also enviromental and social standards together to get both financial and competitive advantages.Sustainable Value method is a new model and is the first real method that can be used to evaluate a company´s resources, both financial, social and enviromental to a sustainable value.This model is used to compare the resource efficiency between companies.In this thesis, a documentary study with an experimental approach has been made.Sustainability reports from six selected companies (in the engineering and forestry sector) have been investigated with respect to their accounting for carbon dioxide, and an experiment using the method ?Sustainable Value Approach? was subsequently performed.

Utvärdering av Sensus amningsutbildning för blivande föräldrar

ABSTRACTStatistics show that breastfeeding prevalence for Sweden has fallen since the mid 90´s. Studies show that breastfeeding offers health benefits to both mother and child and that the mothers' belief and confidence in their ability to breastfeed is a key factor to having a positive breastfeeding outcome. In 2010, Amningshjälpen in collaboration with Sensus studieförbund, started a nursing course, for mothers-to-be, who wished to breastfeed their babies and its aim was to prepare them for a successful and enjoyable experience.Objective: To examine whether a preparatory breastfeeding course can affect mothers' confidence in their ability to breastfeed and if that ability can affect the breastfeeding outcome when the child reaches four months. A further aim is to investigate the experience of  perceived problems surrounding breastfeeding and what affect these might have on the mothers' confidence in breastfeeding when the child reaches four months.Design/Methods: A quantitative approach with prospective experimental design was used to evaluate the study. The questionnaire Breastfeeding Self-Efficacy Scale Short Form (BSES-SF) was used three times to measure women's trust in lactation.

Development of a real-time RT-PCR for quantification of bovine TLR4 mRNA and evaluation of its use during a BRSV vaccine challenge

Utveckling av en LC-MS-metod för analys av gamma-hydroxibutyrat, gamma-butyrolakton, 1,4-butandiol, amfetamin och metadon

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Effekten av högintensiv aerob träning på kognitiva funktioner hos friska unga vuxna

Inaktivitet har blivit ett stort problem i dagens stillasittande samhälle och stor vikt läggs på de intellektuella färdigheterna. Konditionsträningens positiva påverkan på de kognitiva funktionerna har under de senaste åren studerats och resulterat i ett flertal artiklar rörande ämnet. Den forskning som bedrivits har undersökt den kortsiktiga påverkan av kognitionen. Syftet med denna studie var att undersöka den omedelbara påverkan på de kognitiva funktionerna: resonemang, koncentration och uppmärksamhet efter högintensiv konditionsträning samt se om en ökad kondition förbättrade kognitionen hos friska unga vuxna. Syftet med undersökningen uppnåddes genom en kvantitativ single system experimental design studie där författarna gick in som deltagare.

"Hur dricker du?" : En studie av kommunikationsstrategiers utfall hos målgruppen med avseende på olika konsumtionsbakgrund

In this paper the authors aim to examine the effects on consumers using different strategies in a campaign within social marketing. A model by Evans et al (1996) has been used in order to see the different steps in which advertising catches the viewers? attention and eventually leads to action or purchasing. However, in the case of this thesis, the intention of the chosen campaign is to change the consumers? attitudes and behavior towards alcohol.
