In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

Title: Youth unemployment- A study of the tax effect on youth unemployment in 13 European industrial countries Seminary date: 2009-02-06 Course: NEK691 ? Bachelor thesis, 15 p Author: Emma Jonsson Tutor: Klas Fregert Keywords: Youth unemployment, tax, 13 European industrial countries, panel data, multiple regression analysis. Purpose: The purpose is to examine the reasons behind youth unemployment with a special focus on tax policy. Method: By using a multiple regression analysis examined with panel data from 13 European industrial countries for the period 1998 to 2004. The dependent variable youth unemployment is explained by five independent variables.

The aim of this Masters thesis is to investigate the notions and use of non fiction literature of children 9-11 years old. Moreover, this study tries to dissect the underlying concepts that exert influence over the target groups notions and use of non fiction literature. The method and empirical basis of this study is qualitative, with interviews of eight children within the target group. We use a theory of reading exchange to highlight the different areas of usability of non fiction for children. To emphasize how children use non fiction as representative for actual facts, or as non fiction with fictional content, we use a four-field correlation model.

The aim of the study was to investigate the performance of postlingually deaf adults on parts of the swedish dysarthria test Dysartribedömningen, and to compare these results with a matched group consisting of normal hearing speakers without any known speech disorder. The group consisted of 17 participants ranging between 42-86 years of age. Participants were assessed focusing on articulation, prosody, intelligibility and through a self-assessment of communicative participation. There was a statistically significant difference between groups on prosody that manifested primarily as a slower speaking rate in the cochlear implant users. No significant differences between groups as to articulation, intelligibility or communicative participation could be found.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

In order to get a better understanding of the interaction between employees and their technical work tools one needs to know what factors influence the interaction. The purpose of this study was to examine if there is a correlation between the personality traits Extraversion (E) and Neuroticism (N), tested with Eysenck Personality Inventory (EPI), and experience of the new Intranet among employees at The Swedish National Transport Administration (SNTA), and also to gather information of employees? opinions about the new Intranet. A survey, containing questions about the Intranet and a personality test (EPI), was posted on SNTA?s Intranet for eight workdays (N = 88, females = 53, males = 35).

This study deals with pedagogical documentation. With a revised preschool curriculum,where this is a crucial aid for illustrating the learning process of children and educators, aswell as demonstrating the activities of the school, it is of the utmost relevance to further explorethis notion. The study focuses on a single municipality and explores the various ways inwhich its preschools do in reality deal with this issue in correlation with the actual visions andgoals set by that municipality. Through a series of qualitative interviews with educators aswell as with the municipality Head of Education, this study outlines how educational documentationis in fact applied in the schools in question. The gathered data has been interpretedwith a power perspective as well as with a sociocultural perspective in mind.

Equine cutaneous melanomas arise much more often in horses with a grey coat color than in horses of other colors. Some scientists have in different studies come to the conclusion that the melanomas are neoplasms which can be classified by examining their histological and macroscopic features. The more defined and demarcated a tumor is, the more benign it tends to be. Other scientists believe that the skin lesions are the result of a pigmentation disorder that is linked to the greying of the coat color. According to this theory, the lesions are not malignant although they have the ability to metastasize.

This essay aims to explain the fluctuations in the Swedish transition rate to higher education between 1923 and 2002. With theories of human capital, and screening, as points of departure, seven variables are selected and their correlation with the transition rate investigated by use of graphs and tables. The variables are unemployment, youth unemployment, the supply of academics, cohort size, number of high school graduates from programs preparing for ensuing studies, relative wage trends for worker categories with differing levels of education, and structural phase. Results show that no single variable nor the theories of human capital or screening can explain the fluctuations in transition rate in full. Instead I propose a theoretic model which amalgamates the above and places risk aversion as the driving force behind the individual?s educational decision.

There is a known link between relative deprivation and street crime among market liberal countries. Although some research has been done with cross-national data, there is none to suggest that the observed link is as valid in a country well known for its extended welfare and generous social expenditure like Sweden. The following study uses longitudinal data to see if this recognized link between relative deprivation and street crime also stands in a country with almost a century long tradition of striving for social-, economic- and cultural equality. Even though Sweden, over the last decade, has been subjected to a series of deregulations due to policy changes at national level, and with a following rise in inequality, it is still considered to be one of the most equal countries in the west. It is therefore not unlikely that the high degree of social security will reduce the negative impact of relative deprivation on social relations among its citizens, perhaps enough so that the correlation will be significantly weakened.

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.

The aim of the present study was to estimate the correlation between Euro NCAP pedestrian rating scores and injury outcome in real-life car to pedestrian crashes, with special focus on long-term disability. The study also surveyed most frequently injured body regions and risk differences for specific elements of pedestrians hit by cars. Another aim was to determine whether Brake Assist systems affect the injury outcome in real-life car to pedestrian crashes and to estimate the effect in injury reduction of a high Euro NCAP ranking score combined with Brake Assist.In the current study, the Euro NCAP pedestrian scoring was compared with the real-life outcome in pedestrian crashes that occurred in Sweden 2003-2010. The real-life crash data was obtained from the data acquisition system STRADA, which combines police records and hospital admission data. The medical data consisted of International Statistical Classification of Diseases and Related Health Problems (ICD) diagnoses and Abbreviated Injury Scale (AIS) scoring.

In the year 2007 the Swedish National Heritage Board released directions for how the contractarchaeology in Sweden should carry out their work. These directions stressed that a differentapproach to the archaeological finds should be used ? that would lead to a higher degree ofselection than before. The purpose of this essay is to find the reason why this change indirections occurred, and this is done by a study of the history of the rescue archaeology inSweden. The other purpose of this essay is to examine if the excavation strategies inarchaeological excavation reports from different times, correlates with the general guidingprinciples for the contract archaeology in Sweden of that time.There are several reasons why the change in directions occurred, but it seems as the mainreasons are practical.

There are several ways to identify individuals with dry mouth, but there are few studies made in which the different methods have been compared with each other.The aim of this pilotstudy was to compare different methods for identifying individuals with dry mouth. Fifty individuals aged 50 to 75 years were included in this studie. These where randomly chosen among patients at the dental clinic at Kristianstad University College. Four different salivary measurements were conducted: 1) collection of unstimulated saliva, 2) collection of stimulated saliva, 3) the so called ?mirrortest?, and 4) analyse using cottonrolls.
