Självskada (NSSI) och externaliserade problem
Med utgångspunkt att självskadebeteende är ett internaliserat problem är syftet med studien att i en ungdomspopulation undersöka om självskadebeteende även är länkat till externaliserade problem. Vi undersöker även om självskadebeteende hänger samman med att i olika miljöer utsättas och utsätta andra för negativa beteenden. Studien använder redan insamlade data i forskningsprojekt kallat - ?Sju Skolor?: Center for Developmental Research (CDR). Data samlades in från 1478 högstadieelever.
Industriellt köpbeteende av utlandsresetjänster
The purpose of this thesis is to examine the organizational buying behaviour in the purchase of travels abroad. We have conducted a case study of two companies, one medium sized and one larger. Our empirical studies have shown that the companies? buying process is divided into two types, the process of recruit a new travel supplier and the process of a straight rebuy of a regular travel service. In the recruiting process we found that the evaluation process of the purchase is an ongoing process that contradicts estab-lished theories.
Hur kan studie- och yrkesvägledaruppdraget förstås?
The main purpose with this study was to investigate how study- and careers counselors active in primary school, secondary upper high as well as colleges describe regarding satisfaction of assignments and suggestions on their development. The study also included in what extent pure guidance tasks cover these assignments as well as what criteria affects these.Six study and careers counselors were interviewed during this study, all active in the three separate educational programs. Their responses regarding what tasks are included in their assignments as well as experiences are in line with previous research. The conclusion drawn from this study shows deviational results in-between the three educational programs, this regarding guidance tasks in their assignments. The conclusion strongly pinpoints that criteria as ?time? and ?need of guidance? affect to what extent guidance tasks fills these study and career counselors assignments..
Barnbibliotek på Internet en granskning av fyra barnbibliotek på Internet i Sverige och USA
Barnens bibliotek, a Swedish Childrens Library on the Internet with a nationwide assignment is compared to three Childrens Library in the USA with local assignments. All four Childrens Libraries on the Internet are compared in terms of content, form, purpose and if they stimulate childrens intelligences according to Howard Gardners theory about multiple intelligences. Three different instruments are used to review the websites. The instruments are created on the basis of literature and the website Barnens bibliotek. To complement these instruments, written interviews are performed with librarians responsible for each reviewed website.
Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning
Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..
Det ryska barnbibliotekets roll och överlevnad i dagens Ryssland : En fältundersökning på barnbiblioteket i Pskov
In an international perspective the Russian children s library is a unique institution, being solely committed to children up to 14 years of age. In Russia of today it is, however, being exposed to hard pressure as the economical and social conditions have changed dramatically since the collapse of the USSR. My interest lies in examining this change of living conditions for the children s libraries and how this in turn affect their work and role in the present state. In order to view this change in a longer perspective, I compare the situation for children s libraries during the time of communist regime with that of today using documents about and from children s libraries. I have studied its legal position and conditions, financial and political state, and how the modern society affects children and youth, especially their daily cultural life.

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Munhålestatus hos arbetande hästar :
Seventy-two working horses (they had been ridden with bit and bridle within the last two weeks) were examined in the oral cavity. Findings and status were noted. The horses were randomly chosen among individuals without clinical symptoms from the mouth and gastrointestinal system.
The result showed that 93% of the horses had changes in the mucus membranes, 86% in the form of ulcerations. The P2 region was most commonly affected followed by wounds more caudally in the mouth (P3-M3 region).

Skolgård : Ett pedagogiskt verktyg för fritidspedagoger
The present study aimed to replicate Tversky & Kahneman's' survey of 1981 The Asian Disease Problem. A survey was conducted on the Internet (N = 200). An identical problem was added, yet with The Swine Flu as the disease. This was done to be able to investigate if there are any order effects, and also if it matters whether the mentioned disease is fictional or real. The results show the same results as Tversky & Kahneman already noted; positively and negatively framed problems generate different responses from the participants.
Hur påverkas beteende/känslor och fysiologiska faktorer på människa och häst vid interaktion mellan parterna? :
The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments.
Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.
Konstruktionen av ett socialt problem : en diskursanalytisk fallstudie av hur hedersrelaterat våld återges i dagspress och fackpress mellan åren 1997 ? 2007
The purpose of this paper was to describe how a phenomenon is constructed into being a social problem, by studying articles on honour killing in the Swedish daily press and in the technical journal Socionomen. The main questions were: can different discourses on honour killing be identified, and if so, have they changed over time, and are there differences between the discourses identified in the daily press and in Socionomen? The method used was a qualitative analysis of discourse influenced by Faircloughs Critical Discourse Analysis. The main conclusion was that honour killing has been textually constructed as a social problem in the studied media. There was one main discourse which clearly pointed out groups as bearers and victims of the social problem.
Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :
Background
Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses.
The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

Matematisk problemlösning i grupp
This study illuminates one part of the mathematic teaching in school, which is mathematical problem solving in groups. It examines teacher?s and student?s ideas about what conditions it takes to be able to learn in groups. Further on, it studies the importance of group structure when it comes to working with mathematical problem solving in groups from a process focused and/or a product focused learning. Through observations of student groups and interviews with the students and the mathematic teachers, the material has been compiled and analysed under three different headings: conditions for learning in a mathematical problem solving situation, importance of group structure in a mathematical problem solving situation and process versus product.
