The vegetation?s impact on erosion control is widely explored, even though research? results are scattered where it suggests a both positive and negative relationship between roots and erosion tendency. Research has measured the roots? impact on erosion by many different methods, hence the aim of this study is to offer a clearance of what factors play an important role in the choice of appropriate species controlling river bank erosion. I have therefore studied 17 articles concerning vegetation and erosion control, which were found in different databases such as: Web of Knowledge, Biological Sciences, Academic Search Elite and Google Scholar.

Background: Mental health problems among children and adolescents have increased. The school is an important arena for prevention of mental health problems. There is a huge demand for successful interventions. SEL is a method that aims to increase the social and emotional competence among children and adolescents. The program SET applies this method.

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

National and international studies, such as PISA and TIMSS, which are part of the national evaluation system, are carried out continuosly. Skolverket, in collaboration with researchers, are responsible for the implementation, evaluation, and analysis of the studies. National results show an increasing percentage of pupils who do not reach the goals in mathematics. The last completed international studies PISA 2009 and TIMSS 2007 show an impaired trend of knowledge, in international comparison. Moreover, studies also show that the differences between schools and also within the same school in Sweden have increased.

The purpose of this literature review was to find common factors for the persons who predispose to eating disorders. These factors shall help the nurse to recognise early signs of eating disorder behaviors. The literature review is directed to the nurse and will answer the issue: Which groups in the community run the risk of developing eating disorders? Furthermore, this knowledge shall lead to a better understanding of persons having eating disorders and be used as an aid in his/her encounter with these patients. The method was a literature review based on eight scientific articles, which were interpreted on the basis of the competence of the nurse.

Obesity and overweight are today classified as one of the largest epidemics in the Western world and is threaten a large part of the population. As a reaction to this a major health trend has emerged in recent decades. Every day consumers are exposed to information from the media about what is healthy or unhealthy to eat and the recommendations change frequently.There is great interest in healthy food on the Swedish food market, but still healthy foods only represents a small proportion of the total food sales. The essay examines the gap between the current and potential demand for healthy food and if it can be explained by any of the following factors: lack of information, price, taste or cognitive behavioral.To study these questions a quantitative method have been used and 213 questionnaires were collected. The intention is to draw general conclusions about the entire population.

The globalization of today?s society has enabled consumers to acquire products and services from all over the world. Global organizations have the entire world as a playfield and offer products and services across markets. Regardless perception and transparency of the global market, consumers are still individuals. Consumers may have different perceptions and ideas about products, their functions and usage.

The telecom and the IT-industry are converging, which creates new possibilities and threats for both existing mobile handset vendors and new entrants originating from the IT-industry. The purpose of this thesis is to explain how IT-players? entrance in the mobile handset industry affects the industry in regards of key success factors and value chain structure. This study has used dynamic theories to describe the mobile handset industry. The theories have helped us in understanding the characteristics and drivers of the industry and thereafter to identify the key success factors.

Bakgrund: Forskning pa?visar pa? skolor som arbetsplats en o?kad stressniva? och minskat va?lbefinnande. Fokus i denna studie var utifra?n detta att underso?ka hur rektorn i sin ledarrollresonerade kring motivation och personalens va?lbefinnande pa? arbetsplatsen ur ett salutogent perspektiv samt att se om rektorns fo?rsta?else av dessa begrepp ansa?gs vara ett redskap i den kommunala grundskolan fo?r att utveckla sin personal.Syfte: Studien utforskade hur rektorer i kommunala grundskolan uppfattade att de motiverade sin personal och skapade va?lbefinnande pa? arbetsplatsen.Metod: Elva kvalitativa intervjuer med rektorer gjordes. Data analyserades genom en kvalitativ inneha?llsanalys.

The aim of this study is to illuminate factors in nurses´ work, which can cause a state of exhaustion called burn out. The results indicate that work related mental illness is a lengthy process that gives rise to both physical and psychical problems. These problems might lead to a state of burn out. However, several authors prefer to use expressions like exhaust syndrome or exhaust depression as they are criticising the concept of burn out. The study is a literature analysis of 11 scientific articles that have been scrutinized using the criterions presented by Polit et al (2001).

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on the target cell. Which effect that is achieved depends on many factors. Thus, each of the 24 known FGFs different biological responses. The FGF receptors (FGFR 1-4) initiates different intracellular pathways which in turn leads to different biological responses.

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.
