Today the Internet is used more and more as a transportation for information. Much of the information is confidential and should not be read by those not privileged. To protect the information from unauthorized access cryptography can be applied. The cryptography algorithms in use today all have their pros and cons. They are therefore suited for different applications.

Om inget görs, beräknas icke smittsamma sjukdomar öka med 17% på global nivå de kommande 10 åren samtidigt som det finns ett ökat behov av ekonomisk konsolidering. Ett fåtal kommuner ägnar sig åt ett systematiskt folkhälsoarbete och det finns en osäkerhet kring hur ambitionerna rent praktiskt ska uppnås. Endast med hänsyn taget till strategisk planering och beaktande av komplexitet i hälsosystem och hälsointerventioner är det möjligt att hitta hållbara modeller för hälsofrämjande och förebyggande arbete. Sedan drygt 30 år används hälsokonsekvensbedömning (HKB) för systematiskt hälsofrämjande arbete. Ger verktyget tillräcklig information och bakgrund för planering och beslutsfattande på en strategisk nivå? ?Five-Level Framework? (fem-nivå modellen) är en modell för strategisk planering i komplexa system som kan ge svar på den frågan.

The aim of this study was to identify and make transitions in Swedish preschool-class-9-years elementary schools visible with a special-needs educational perspective. Transitions in focus were those between preschool-class and primary school, between grade three and four and the last between grade six and seven.In the 1960?th Swedish elementary school were devided into three levels; primary school, intermediate level school and upper level lower secondary school. Those levels were officially removed when the curriculum of 1994 was introduced. However, in some way such levels still exist, for example in organisation and structure of schools, the curriculum and teacher education.How did school leaders design transitions between levels and which tools were used? What kind of information was transferred to help children with special needs and what was the role of the special pedagogue in the transition process?The study was a combination of a quantitative and qualitative method, a questionnaire survey complemented with qualitative interviews with special pedagogues in three schools in a middle-sized Swedish town.The result of the study shows that schools in focus had a work plan.

The aim of this paper is to study the long-term effects of stuttering treatment according to the Lidcombe Program in Sweden and to answer questions whether underlying factors may have affected the treatment results. Participants were seven children, one girl and six boys aged 7:10-14:2, who all completed Stage 1 of the program approximately 2-7 years ago.The children were video recorded during a conversation with one of the authors and while reading aloud. Before the recording, their parents estimated the level of stuttering according to a Severity Range (SR) Scale. The evaluations were used as reference for determining whether the recordings were representative for the children´s current speech fluency. Proportions of stuttered syllables (%SS) were calculated from the video recorded material and compared with the proportions of stuttered syllables (%SS) at the time when the first stage of the program was initiated.The results showed that the Lidcombe Program had a significant (z=-2.37, p=0.02) long term effect on stuttering treatment for the participants in this study.

This study discloses home-care organizations in one municipality in Sweden and five units work with implementing the social services legislated value base for elderly people. The aim of this study is to gain an understanding of personnel and managers perception of the value base and its implementation in the practical work with the elderly. A qualitative method has been used to analyze the questions raised by the aim of this study. The empirical data was retrieved by semi-structured interviews with managers and their personnel in homecare service The empirical data was analyzed on the basis of the neo-institutional theory, Michael Lipsky?s theory concerning street-level bureaucrats and previous research regarding implementation of social policy and the practical home-care work.

Underdrainage is a costly investment but often a necessity to maintain rationalized plant cultivation, one can also see underdrainage as insurance to successful plant cultivation. Late ripening crops, low yield and difficult tillage cultivation are examples on an insufficient drainage. (Kvarnemo 1983) A drained field rise in land price and the scheme of the tiled drains is seen as a value item. The interest for underdrainage among the farmers follows with shifting economic situations within agriculture and has for long time been low. A big part of the Swedish tiled drainage systems is since 1930 and ahead. Many of these tiled drainage systems need to be replaced or complemented. The life length of one tiled drainage system varies with maintenance but can still remain in good function after 75 years with correct management.

Borna disease virus (BDV) is a virus with capability to cause neurological disease in several species of mammals and of ostriches. Also humans are suspected to be susceptible to the virus, as the viral RNA and antibodies against BDV have been found in some humans with psychiatric diseases, like schizophrenia and depression. In Sweden there is a disease called staggering disease in cats, associated to BDV-infection. This disease often has a fatal progress. Definite diagnosis is reached by histo-pathological and immunohistochemical examination of the central nervous system.

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

Crowdfunding is described as a facilitator for creative entrepreneurs in their gathering of funds for projects. This bachelor?s thesis  aims at finding differences in communication components found between successful and unsuccessful crowdfunding campaigns on one of the most popular platforms, Kickstarter. Through a quantitative content analysis and a rhetorical analysis of literary topoi this study suggests that there are apparent differences in usage of titles, text, visual expressions, rewards and in themes of preparation, humility as well as quality. The findings we present conclude that a campaign with a title consisting of eight words and one punctuation are more likely to succeed than other.

Parenting and parental leave in a career context is a highly topical subject in which discussions about gender equality and corporate discrimination against parents occur daily. Media has recently raised the theory of parenting and parental leave as having positive impacts on personal development, such as creativity enhancement, which may promote the individual's work performance. Despite the subject's significant value for society and organizations, no scientific research is to be found. This paper examines how an individual's creativity at work is affected when becoming a parent and if parental leave has any contributory effect. Furthermore, the paper identifies and scrutinizes four creativity theories that may help explain these changes in creativity.

Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.

My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.

Saproxylic lichens in managed forests have less substrate available than in unmanaged forests due to the shortage of dead wood. However, a suitable substrate for these lichens could be dead branches on living trees. To this date, there has not been any systematically collected data about theabundance of dead branches on living trees and the lichens growing on these branches in managed forests. The aim of this study was to see where dead branches were located on living trees of Pinus sylvestris and Picea abies, how large the surface area of these branches was and what lichens grewof wood on these branches. The study was made in Finspång, Sweden, where 11 forest stands of P.sylvestris and P.

In the democratic process, of discussion and decision making, there is a need of reliable and authentic information. Archives are authentic and reliable information and also provides long term accessibility. But the public archives potential isn´t utilized enough at a societal level. The public archives are organized in a decentralised manner, and there are no common accesspoint at a national level. In the thesis this issue of accessibility and use at a societal level, is discussed in terms of collective memory.

The concept competence is considered to be difficult to define. Therefore, it may be problematic to define competence in business and to evaluate the level of skills of employees (Thomsen, 2010). In this study the aim has been to identify key competencies for employees working as purchasers for Skanska Nordic Procurement Unit (NPU). These key competencies will afterwards help Skanska NPU to evaluate purchasers? level of competence.The theoretical framework of the study consists of three different parts.
