Trots att självkänsla är ett frekvent studerat ämne saknas en allmänt erkänd teori och definition som kan utgöra en grund då självkänsla studeras. Gemensamt för flertalet teorier är att självkänslan grundläggs i barndomen samt att självkänsla rör en persons uppfattning om sig själv och personens omdöme om hur han eller hon uppfattas av omvärlden. Studiens syfte var att göra en psykometrisk utvärdering av en modifierad version av Jag tycker jag är samt att studera formulärets test-retest reliabilitet. Jag tycker jag är utvärderades genom att analyseras tillsammans med andra välprövade självkänsloskalor. Undersökningsdeltagare var 100 psykologistuderande (M = 28.4 år; s = 7.3 år).

This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.

The purpose of this study is to investigate whether intensive teaching of reading strategies at an individual level can affect reading comprehension for students in second grade. A quantitative method with quasi-experimental design is used. All students in the experimental class trained on reading comprehension strategies at their particular level five times each. Before and after training a reading comprehension test was made. The reference class did the same test.

SammanfattningSyfte och frågeställningar: Syfte var att a) undersöka interbedömarreliabiliteten av testerna Neer sign (NS), Hawkins-Kennedy test (HKT) och Jobe test (JT), samt b) undersöka sambandet mellan resultatet vid NS, HKT och JT med resultatet vid muskuloskeletal ultraljudsundersökning hos patienter med subacromial smärta. Frågeställningarna var följande: Hur är interbedömarreliabiliteten för NS, HKT och JT? Vilken sensitivitet och specificitet har NS, HKT och JT som enskilda test respektive tillsammans i ett testbatteri för att diagnosticera subacromial smärta med muskuloskeletalt ultraljud som referensmetod? Hur väl samvarierar ett positivt impingementtest med ett onormalt lågt avstånd mellan humerus och acromion? Finns det någon skillnad av det acromiohumerala utrymmet (AHD) mellan personer med eller utan impingement i skuldran? Metod: 18 forskningspersoner (fp) med skulderbesvär (medelålder 54 år, besvärsduration median 2,25 mån) rekryterades konsekutivt.  Under samma dag undersöktes fp av två sjukgymnaster med testerna NS, HKT och JT. Ultraljudsundersökning utfördes inom åtta dagar och användes som referensmetod vid uträkning av sensitivitet och specificitet för de kliniska testerna.

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

SammanfattningSyfte och frågeställningarHuvudsyftet med denna studie var att skatta reliabiliteten i den svenska Försvarsmaktens fälttest. Ytterligare syften med studien var att undersöka huruvida antropometriska parametrar såsom vikt, längd och BMI korrelerar med resultat på fälttestet.MetodFör att undersöka fältestets reliabilitet genomförde 33 försökspersoner (fp) två fälttest med 48 timmars mellanrum. Fp bestod av endast män där genomsnittsåldern var 22 år, genomsnittsvikt 81 kg samt genomsnitts längd 182 cm. Fälttest innebär att fp springer en sträcka på 2000 m med stridsutrustning som väger cirka 22 kg. Test och re-test genomfördes vid samma tid på dygnet.

The thesis is about exploring possibilities for developing a standardised system solution for micro businesses, this since most of the micro business lack proper system solutions, a contributing factor of this is price and also incompatibility between the solution and the business itself. The system solutions we will refer to are solutions which task is to cover the most important needs that a micro business might have on their system. The main goal with this research is to see if this is possible, and if so, how the developers should think to take it further. We chose to do this by identifying the most significant of needs a micro business has when it comes to this type of system solution.In this thesis we will present three needs which were evaluated and brought forth through the analyses of various interviews and observations we had done during the study. The interviews took place at respective company with their employees and consisted both closed and open questions with our main focus on the open questions because we wanted to obtain as much information from the respondents as possible from several viewpoints.

Syfte: Studien unders?ker hur unga uth?llighetsidrottare upplever externa faktorer som testledare och labbmilj? vid ett VO?max-test, samt hur k?nslor och mentala strategier p?verkar upplevelse och prestation. Den kartl?gger ?ven f?rberedelser inf?r testet och j?mf?r dessa med t?vlingsrutiner. Metod: Sex idrottare (4 m?n, 2 kvinnor, snitt?lder 17,5 ?r) fr?n RIG/NIU deltog i VO?max-test p? l?pband eller cykel. Testen f?ljde standardiserade protokoll och m?tte objektiva v?rden som laktat, puls och RPE.

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

Internet is used today as a traditional medium for information exchange and social interaction. One of these is virtual meeting places where people meet and exchange information, socialize and exchange knowledge with each other. The group has chosen to examine the factors affecting the use of web forums, one of the virtual meeting places that exist on the Internet today. And look at how people use the web forum today in the current situation and how to design a web forum.A survey was conducted to find out how people look at web forums today, 80 people participated, and they got to talk about what they think about different web forums regarding how and why the use these them. Guidelines on how a web forum should be designed were also developed.
