The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.

In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.

I have in my thesis performed a survey that builds on interviews of five former students at Mediepedagogiskt Center (Mpc) that is located at Sundsta-Älvkullegymnasiet in Karlstad which is incorporated into Karlstads-Hammarö comprehensive upper secondary school. The sample group of students all has various withdrawal years between 1997 - 2004. The aim of the survey is to evaluate any direct qualities that these students have had that helped them to get a occupation within the media industry after the completion of their education at Mpc. This survey also tries to evaluate whether the orientation of their particular style of education is a factor for achieving employment. Before 1998 the course was divided into three A and B-level courses within the directions, photography, graphic design, text communication, sound production and film/television. After 1998 these are now divided into one A, B and C level courses, and one another level courses on A and B-level. The result shows that something more than? just? a good schooling with high grades is needed to succeed into getting a occupation within the media sector.

Företag handlar allt oftare internationellt vilket medför att de kommer i kontakt med tullmyndigheten och tullfrågor avseende tillstånd hos Tullverket, tullavgifter, tullager och hantering av tulldeklarationer. Denna uppsats ämnar studera hur medvetna företagsledningar i Sverige är när det kommer till tullområdet och dess tillhörande risker vid bristande tullkunskap. Detta efter att tullombud som sköter tullhantering åt företag och Tullverket anser att näringslivet generellt sett har bristande tullkompetens vilket kan leda till konsekvenser för företagen så som oväntade tilläggsdebiteringar och straffavgifter, som i sin tur kan påverka företagens verksamhet och lönsamhet. Uppsatsen baseras på en fallstudie där nio företagsledningar intervjuats enligt ett strukturerat tillvägagångssätt. Resultatet visar en blandad uppfattning om riskerna med bristande tullkunskap.

This study examines university employees? perception of their employment situation and career opportunities. By tradition, fixed term contracts are used in the Swedish research community due to dependency on insecure funding. There is a current debate that questions this use of insecure employments. The employments are said to negatively affect the university?s societal role and international competitiveness.

Delineation of recharge areas for aquifers is performed in the groundwater mapping process at the Swedish geological survey, SGU. This work is time consuming and performed manually. It is therefore desirable to develop a more general and repeatable method for defining recharge areas for aquifers.The purpose of this study was to investigate two other possible methods to delineate recharge areas for aquifers. The first method was to examine the possibility of using the topography of the bedrock to define the recharge areas for aquifers. To enable this, a method for generating the topography of the bedrock was developed.

The technical evolution has a great influence on the public libraries. Electronic media becomes more and more common. This Master´s thesis is based upon the Swedish Library law 9§ (SFS 1996:1596) which says: Public- and school libraries should pay special attention to children and teenagers by offering books, information technology and other media, adapted to their needs, to encourage development of language and stimulate reading. From this point of view we have examined why the children´s departments in public libraries offer CD-ROM games which are based upon characters from the literature, how they are used in the daily activity and how they can contribute to the development of the children´s department.We have made literary studies and empirical investigations including interviews, observation studies etc. The results from this studies shows that both young and adults appreciate the CD-ROM games.

Sammanfattning: Examensarbete belyser om det är möjligt att kategorisera studie- och yrkesvägledares upplevda arbetssituation i KASAM. För att kunna kategorisera utifrån KASAM vill vi veta hur studie- och yrkesvägledare upplever sin arbetssituation och hur deras kompetens tillvaratas inom deras arbetsorganisation. Dessutom har vi valt att ställa frågor om hur arbetsgivaren ser på deras profession och vilka möjligheter de har till kompetensutveckling. Examensarbetet är en kvalitativ studie med sex olika studie- och yrkesvägledare yrkesverksamma inom statlig, kommunal och privat arbetsorganisation i västra Sverige. Vi kontaktade studie- och yrkesvägledare för att höra om det fanns intresse att delta i en intervju.

The aim of this thesis is to study whether social welfare secretaries experience occupational pride and what affects this feeling. Previously made research indicate that occupational pride is essential for performance and work-related health. Research has also shown that social welfare secretaries often experience unhealthiness due to working conditions and a lack of professional self-esteem.This thesis is based on four qualitative interviews which have focused especially on critical incidents, according to the critical incident technique. This study has a hermeneutic, interpretative approach. As a theoretical framework, Pierre Bourdieu? s theory on social space and positions aswell as Aaron Antonovsky´s theory on Sence of coherence have been used. The result shows that the interviewed social welfare secretaries do experience occupational pride.

The aim of this study was to examine how the interviewed primary teachers in two schools situated in the Stockholm area understand themselves as teachers in relation to their image of the good teacher. The research questions were: How do the informants discuss their image of the good teacher? How do the informants describe their own role as a teacher?A qualitative method, by interviews made with four primary teachers, was used to collect data for the examination. The results from the interviews were analyzed and discussed from the theories and earlier research concerning the role of the teacher and what they describe as the good teacher. The theoretical connection of this study was based on the theories of Vygotsky, Piaget, Bruner, Dewey, Dreikurs, Kounin and Glasser concerning the relationship between the role of the teacher and learning.

The aim of this study is to increase knowledge and understanding of free play or free fun time importance for children of age around five years in preschool, in order to promote children?s development and learning. The focus was on exploring and better understanding of teacher?s and educators? approach to the free fun play time as a tool in their educational work, and also about their own role in this context as well as analyzing of forms, rules and structures spontaneously created by groups of children having free play fun time. Another important moment of this study was to give more light on approaches to this issue in education theories by Piaget, Vygotsky and Freud among others.As to the practical experimental part of the study it has been performed at a preschool and kindergarten in a suburb at the outskirts of Stockholm, with four employed educators there and with groups of children of age around five.

Bakgrund: Sjuksköterskor som arbetar på akutmottagningar förväntas ha en hög kompetens inom traumavård. Med hög kompetens menas att de utför ett komplext och avancerat arbete och har ett stort ansvar i det initiala omhändertagandet av traumapatienter. Syfte: Syftet med studien var att beskriva sjuksköterskors självskattade kompetens inom traumavård på en akutmottagning Metod: Studien är empirisk suveystudie med kvantitativ data som samlades in genom att en enkät delades ut till sjuksköterskor på en akutmottagning. Sjuksköterskorna fick skatta sin kompetens inom traumavård utifrån svensk sjuksköterskeförenings sex kärnkompetenser samt efter deras formella och kliniska kompetens. Resultat: Huvudresultatet är att nästan alla (94%) av sjuksköterskorna vårdar traumapatienter oavsett erfarenhet och formell utbildning.

The aim of this master's thesis is to describe the visibility of the university libraries in the strategic documents from the actual universities to which they belong. And also, the image of themselves they send out, are examined. By examining different kinds of descriptions we want to get a clearer picture of how and in what amount the libraries are mentioned in highest level strategies. By doing this we expect to find out the libraries' strategic role in higher education and research. The research questions are: What role and function are assigned to the university libraries in strategies created by the schools' highest administrative levels? How do the libraries present themselves in their own strategies? The approach is cross sectional and the time frame is year 2008.

Nationalism during the early 20th century, was often shaped around efforts to create feelings of fellowship within the frontiers. Fellow feelings was considered as a necessity to convince the people that their efforts served mutual goals.Beginning in the 19th century, the European nations experienced a great many projects for this purpose. In the early 20th century the efforts grew. The danger of war and the competition for economic power, contributed the increase of nationalist movements. At the same time, many influential intellectuals also expressed apprehensions about the urbanized way of life; measures were necessary to secure the future success of the nation.The national movements in Sweden, played a prominent role in the creation of a greater patriotic feeling.
