The aim of this study has been to create an understanding for the situation of an often forgotten group in foster care, the carers? own children. Our main focus has been the experience this group has of foster care, their experience of participation in caring for the foster children and their possible need of support and help. Our chosen method has been qualitative interviews with six adult children of foster carers, two men and four women. The theory used in this study has been Sense of Coherence.Our interviewees gave mainly a positive description of being part of a foster family even though they could give examples of difficult situation and of loss.

This study is a survey concerning learning on equal terms. The purpose of the survey is to get a look into how teachers of today integrate students to obtain an individually adapt education. A good education is where every single student can evolve from an individual level and how education is adapted to let high-achieving students keep their motivation and thus develop from their own level of knowledge.Data has been collected through a qualitative method using semi-structured interviews. In the result the answers of the interviews are presented and it shows that teachers turn their focus towards low-achieving students. Low-achieving students are more in need of support to reach the required amount of knowledge, but that the high-achieving students must not be forgotten by the teachers. .

This paper deals with the question of why companies choose to go on trade fairs and exhibition examines how the media works. The essay's main focus is on stand contractors and why those hired to produce other company stands. The study is based on three interviews, a visit to a trade fair and a questionnaire survey. Together with the relevant literature is given a clear picture of how companies are thinking in their choice of attending the fairs, but also why stand contractors are involved in the process. We concluded that some companies do not know why they participate in fairs and many feel compelled to contribute to not be forgotten in the market.

Den här studien berör några av de miljöpsykologiska grunderna i Alnarps Rehabiliteringsträdgårds uppbyggnad. Den ger förslag på hur karaktären rofylld kan förstärkas och hur säsongen kan förlängas i den restorativa delen av välkomstträdgården med växter som tilltalar flera av våra sinnen. Deltagarna som kommer till trädgården har i regel stressrelaterade åkommor såsom utmattningssyndrom och har varit sjukskrivna en längre tid. De är ofta mycket känsliga på grund av fysisk och psykisk utmattning. Studier visar att deltagarna har behov av en kravlös miljö där de kan få vara ostörda.

Uddebo avloppsreningsverk är det största i Luleå kommun, med ungefär 61 000 anslutna personer i Luleå tätort och omkringliggande byar. Man har haft vissa problem i reningsverket de senaste åren ? misstankar finns att det kommer in miljöfarliga ämnen som stör bl.a. de biologiska reningsprocesserna i verket. Dessutom har slammet emellanåt uppvisat för höga halter av tungmetaller för att det ska få spridas på jordbruksmark.

Syftet med studien är att undersöka hur barnperspektivet används i det dagliga arbetet. Avsikten är också att undersöka hur barnens inflytande ser ut över de beslut som fattas kring deras livssituation. Studien genomfördes genom intervjuer med socialsekreterare på socialtjänsten. Teorin som användes är systemteori, även barnperspektivet och ett teoretiskt perspektiv på dominansförhållanden i samtal med barn tillämpas. Med hjälp av ovan nämnda teorier och teoretiska perspektiv analyseras och förklaras hur socialsekreterarna använder barnperspektivet.

My work is based on a text analysis of media production of the female offender. I found it interesting how women were presented as victims rather than perpetrators. The media have in recent years grown tremendously and this also impacts on people and what is important. The notion of how a woman should be and how a female offender should be is extreme. The material for my work is articles found on the Internet in daily newspapers websites.

As to now, no study has been made of the mica tempered pottery found along side the asbestos tempered pottery in Norrland during the Bronze Age and Early Iron Age. Its occurrence has previously only briefly been noted in a few published works and the dating and geographical distribution of mica tempered pottery in the north of Sweden has to a large extent been unknown. This paper aims to compile the available information about this type of pottery and the locations where it has been discovered in order to date and explain the occurrence of mica tempered pottery in Norrland. It's also suggested that the occurrence of mica tempered pottery is connected to the spread of the early metalwork from the east to areas that today makes up the north of Norrland..

In printed text, sound is a somewhat forgotten aspect. The recitation of text is vital in areas like poetry and oratory, but still has no distinct technique of being communicated. Emphasis of a word might be expressed through italics, but no canonic character set or system for vocal delivery of texts exists. With this essay we are creating a foundation for a development of such a character set or system. By studying existing visualisations of sound and comparing these with semiotic and perception-based theories we obtain useful insights for a prospective system for visualisations of vocal sounds.We conclude that the aspects of sound one wants to visualise must be carefully defined since the viewer cannot process infinite amounts of information.

Urinvägsinfektion är den vanligast förekommande vårdrelaterade infektionen varav urinvägskatetrar orsakar cirka 90 %. Syftet med studien var att undersöka om val av metod och material för urinvägskateterisering kan minska förekomsten av kateterrelaterade urinvägsinfektioner. Uppsatsen genomfördes som en litteraturstudie. Femton vetenskapliga artiklar granskades och analyserades. Katetrar belagda med hydrogel, silver och antibiotika tycks ha en hämmande effekt gällande uppkomst av urinvägsinfektioner.

This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.

Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.

The aim of this study was to provide an understanding of the situation of an often forgotten group in foster care, the carers? own children. Our main focus was to explore this group?s experience of foster care, their experience of participating in caring for the foster children and their possible need of support and help. Our chosen method was qualitative interviews with six adult children of foster carers, two men and four women.

In Sweden between 800.000 and 900.000 people have some kind of alcohol related addiction. Each and everyone are expected to have three relatives who in some way are involved in the abuser´s way of life. The consequences of living close to someone with an abuse of alcohol is described as a chaotic life with extreme emotional stress, fear and anger.The aim with our essay has been to look into how social workers are describing their work, from the relatives´ point of view. We also wanted to understand how the relatives´ situation can be. We reached our aim through interviews with social workers and by literature studies.The primary conclusion of the essay is that the dominating theory is that addiction is an illness.
