"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.

Temperature monitoring during transport of test samples

Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval.

Hur har det svenska handelsmönstret påverkats av ett medlemskap i EU?

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.

Svensk delnormering av Lundamaterialet för åldrarna 3:0?5:11 år och undersökning av materialets effektivitet

The purpose of this study was to collect Swedish normative datafor Lundamaterialet for children aged 3:0-4:5 years. Another aim was toexamine the effectiveness of the test; if it elicits adequate responses fordeciding if a child has acquired a specific language structure or not.Normative data was collected for 195 children with typical languagedevelopment. Participants were recruited from pre-schools in themunicipalities of Göteborg, Mölndal, Härryda and Skövde. This studypresents normative data for 79 children constituting the three youngest halfyeargroups. Results show that the children had acquired more than half ofthe investigated phonological and grammatical structures and that the olderchildren had acquired more structures than the younger ones.

Får elever bättre uppmärksamhetsförmåga efter fysisk aktivitet? : En experimentell studie om fysisk aktivitets påverkan på uppmärksamhet

The aim of this study is to find out whether there is any difference to be found in the attention ability before and after physical activity. The method used in this study was made of an experimental design. The participants were chosen through a cluster sampling and thereafter divided into a control group and an experimental group. A total of 64 pupils from upper secondary school participated in the study, 25 of them in the experimental group and 39 of them in the control group. Since the measure was repeated, both in respect of time and the comparison between the groups, a mixed design was used.

Detektering av sprickor i vägytor med hjälp av Datorseende

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Statusbedömning av dricksvattennätet i Hästskoområdet i Järfälla

Chlamydophila psittaci is a common cause of diseases in parrots ranging from being less serious to more serious. It is also a zoonotic disease which poses serious health problems to humans. The disease is highly under diagnosed. The symptoms in birds are nonspecific and may be indicative of many different diseases which make it harder to diagnose and treat. The purpose of this study was to investigate the prevalence of C.

Stress test methods : a potential approach to hurry up shelf-life tests on oat products

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

Wii Sports och Sport : En jämförelse av fysiska och emotionella skillnader och likheter i träningsspel jämfört med riktig träning

AimThe purpose of this study is to compare the level of activity between playing wii Sports Tennis and wii Sports boxing, and the usual sports, and to see how the two variants are perceived.Issues:- How much strain ratio and energy consumption it gives to exercise wii sports compared with the playing of sport for real?- How do the test participants experience the different tests?- How are the two wii sports games against each other in terms of activity and fitness in the school environment?MethodThis is an experimental study in which 10 test participants (5 men and 5 women) have carried out four different physical tests. The tests consisted of either playing an exergame or playing a sport for 25 minutes. Physical activity was measured during the test using a heart rate monitor. All test participants completed all tests in the same order.

Bankers identifieringsmetoder : Nu och i framtiden

Keywords: ID-method, internet, security, digitzing, bank Background: The digitizing of our society continues to grow and more parts of our lives is spent on the internet. The banks are one of the institutions that is at the forefront of this development since they established themselves on a early basis. The banks meeting points have since this establishment moved from the regular bank office out on the internet. A problem that has occurred during this transfer is the possibility to positive ID a customer in a virtual world. It is essential to offer the customer methods to identify themselves that are both safe and easy to use.

Test av spädbarns nyhetspreferens med ögonrörelsemätare

Fagan Test of Infant Intelligence (Ftii) är ett parjämförelsetest som mäter spädbarns intresse för ett nytt visuellt stimuli när detta presenteras tillsammans med ett stimuli redan känt för spädbarnet, kallat nyhetspreferens. Även om Ftii har visat sig fungera väl vid bedömning av spädbarns kognitiva nivå kan testet förbättras på ett antal punkter. För att uppnå reliabla resultat har försökspersonerna ofta testats vid ett flertal tillfällen. För att undersöka möjligheterna att ytterligare validera erhållna resultat från Ftii har en version av Ftii skapats för att utföras med en ögonrörelsemätare. Denna version, kallad Ftii-Ö, har testats med hjälp av en spädbarnsgrupp och en vuxengrupp för att på så sätt utvärdera för och nackdelar med ett test utfört på ögonrörelsemätare.

Metodik för utmattningsberäkning av svets i vibrationsmiljö

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
