Äldre personers skattningar av ålder hos maskerade män

Syftet med studien var att undersöka hur hög precision äldre personer har när de ålderskattar maskerade och omaskerade ansikten. 21 kvinnor och 19 män, totalt 40 deltagare med genomsnittlig ålder på 57,7 år fick skatta åldern på 30 maskerade och 30 omaskerade ansiktsbilder. Samma stimuluspersoner användes med och utan mask. Stimulusbilderna delades upp i grupperna yngre (18-32 år) samt äldre (39-72 år). Resultatet visar att omaskerade ansikten skattas med högre precision än maskerade ansikten och att kvinnor hade en högre precision än män.

Estimation av bostadsrättspriser i Stockholms innerstad medelst multipel regressionsanalys.

This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.

Studie av integration mellan rategyron och magnetkompass

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

Access to the market - a question of collaboration?

When contemplating entering an alliance the rationale behind the decision should differdepending on the size of the companies involved as well as on other important factors. The importantfactors influencing the decision are related to the resource pooling potential of the alliance,the power structure along with the business network the companies are a part of. Theanalysis has shown proof of a need for cooperation if one wish to succeed in the telecommunicationindustry and it has also determined which resources that are deemed to be most important toget in touch with, for our study object, to facilitate its access to the market. Those resources aredefined as a direct channel to the customer, funds/capital and the access to relevant businessnetworks. To get in touch with these lacking resources, three alternative approaches has beenproposed; all of them involving a strategic alliance decision.

Att studera validerade mätinstrument : för att mäta barns oro inför dagoperation

Background: Anxiety with children before surgery is well known. From the 1950s there are various assessment instruments. Despite that most day surgery units offer preparation for children and parents, there are many children who exhibit a strong anxiety the day of surgery, which can lead to postoperative behavioral changes. Today the nurse estimates the anxiety of a child on personal experience and knowledge, forming the basis for estimation whether the child is in need of sedation or not. The purpose: of this study was to evaluate instruments that the nurse can use in measuring the degree of anxiety of children before fast clinical settings, such as day surgery.

Vindkraftsplanering i skogsmark

The aim of this study about wind power planning in forest was to examine the factors and restrictions, which represent technical limitations, biodiversity, tourism and amount of energy for wind farms in Kronoberg County. Suitable areas for wind power were identified from the collected information about planning principles and potential conflicts. From the suitable areas the potential energy gain is calculated. Methods used were mainly a literature review, interviews with experts and practitioners, GIS analysis and a rough calculation of the energy gain. The section of information and facts describes in general wind power planning and possible conflicts.

"Kuratorns roll? Grundtanken är väldigt positiv": en undersökning om sjuksköterskors syn på kuratorn i den medicinska organisationen

In this master thesis, which is made in a qualitative manner, we have as purpose to investigate the nurses' estimation of the hospital welfare officer. We find it interesting to take a closer look at their opinion, because of our earlier, bachelor thesis, based on the same subject, only then in the welfare officer´s perspective on themselves. We have interviewed ten nurses and our questions at issue were the following four: Where in the hospital´s hierarchy do the nurses place the welfare officer? In what way do the nurses look at themselves and on the fact that they are leagally authorized? How do the nurses define the welfare officer´s occupational sphere and his part of the medical care? Which opinion do the nurses have on the co-operation with the hospital welfare officer? The primary information, together with two maintheories and a collection of litterature on the subject have helped us to answer the four questions of issue. We have found that the results we see, in some ways are compareable to our first investigation.

Effektivare ytterbelysning inom Karlstads Bostads AB :  

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

Kommunikationens betydelse : fallstudie på införandet av balanserade styrkort i Gotlands kommun

This study raises the question how the implementation of the balanced scorecard in the municipality of Gotland has been influenced by the way of communication. A case study is made in the administration of Social-and care management on Gotland. We have been focusing on two different ways of communication. The first one is Shannon and Weavers model where communication is explained as a transmission of a message through a channel to a receiver. The other one is sensemaking where it is focal to give the information meaning.

Askåterföring värt besväret? : en fallstudie av följderna av Stora Ensos försöksverksamhet med askåterföring

This thesis reports on a case study of a forest company, Stora Enso, and their experience from a number of trials and experiments with ash recycling. A literature survey and a total of eleven in-depth interviews were carried out. Ash recycling was found to be the concern of three different divisions of the company. The pulp industry which produces the ash, the forest division which would be responsible for identifying land and spreading the ash, and Stora Research, which has had a major part in the design and implementation of research trials. Lacking an overall company decision on ash recycling the matter is left to the individual divisions.

Nytta, skada och kostnader vid screening för bröstcancer med mammografi

The efficacy of screening for breast cancer with mammography has been a subject of controversy during the last decades. However, the general opinion is now that screening reduces mortality in breast cancer (Zackrisson, 2006). It is nevertheless important to weigh the efficacy against the harm and costs associated with screening. Cost-utility and cost-effectiveness analysis of screening have generally failed to incorporate side effects such as anxiety and discomfort related to screening tests and the following diagnostic tests (Gyrd-Hansen, 2000). This study seeks to include such side effects in a cost-utility analysis.

Undervattensvågbrytare - En modellstudie

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Sociala medier och turism : Logga in! Hela värden får veta vad jag tycker, men vad tycker turistaktörerna?

The purpose with this study is to enlighten and discuss the information and communication which is spreading through social media, about the tourist operators and also to examine the operators view on social media. Social media can be described as a tool to use word of mouth on the Internet. To make this possible, five actors involved in tourism were picked on Gotland and interviewed for a content analysis. The results showed that the use of social media as an information channel before the consumer buys a trip, has increased. The study also shows that the selected actors have a lot of work to do, before they understand how to use the social media in their best interest for further developing their companies.
