Striga hermonthica, a parasitic weed, has long been believed to be correlated with the declining soil fertility status. However scientists have recently come to question this statement since some recent studies have shown contradictive results. To investigate whether soil fertility status and infestation of Striga hermonthica were correlated and the impact of it were caused by farmer management, 120 farmers in Western Kenya, where Striga hermonthica infestation is prone, participated in this study. In three districts with two sub-locations each, farmers answered a structural questionnaire and identified two fields, one with high and one with low soil fertility. These fields later came to be the basis for this study and soil were therefore also sampled from them.

Students today, in the banking system, are the least loyal group. Students are also the most costly group due to the large investments, made by the banks, for them. Banks have generalized all students in one category and have adapted their offering regardless of students? social statues. As the students banking needs are dependent on their position in their lifecycle, generalizing them in one group is not optimal.The aim of this thesis is to investigate those factors which influence students? choice of bank.

Attitudes towards violence were assessed using both implicit (The Single Category Implicit Association Test; Karpinski & Steinman, 2006) and explicit measurements (a Feeling Thermometer). A group of criminals showed more positive explicit and implicit attitudes towards violence than a group of non-criminals. In addition, The Aggression Questionnaire (Buss & Perry, 1992) revealed significant differences in aggression between the groups; criminals' mean scores were higher on all four subscales (physical aggression, verbal aggression, anger and hostility). Furthermore, significant correlations were found between all the measures, including the implicit and explicit attitude measures. The findings support the validity of the SC-IAT as an implicit measure of violent attitudes.

In this thesis I discuss and analyze different factors, and different circumstances, that influence identity negotiation among the north american indians. I do this mainly by using two models.The first one is Druckmans three dimensions of identity; negotiating identity, durability of identity and spread of identity. Depending on how the identity fits in these dimensions one can se if, or how, they influence the negotiability.My second model for analyzing is Reeds ?fasteing and unfastening identity?, using this model I have tried to understand during what circumstances the identity is negotiable. The identity is more or less negotiable depending on where the indians live, who they are living with and also on their inheritance.My results shows that the indian identity is changing and developing over time but the main characteristics still remains the same.

The purpose of this study is to find out what the educators idea of educational documentations in ratio to childrens inclusion and impact in pre-school are, together with the child's own perception of the concepts of documentation. We proceeded from the following issues: What are the significance of educational work according to the teachers? What is the teachers idea of a childs impact and inclusion in educational documentation? In what way do the children have influence over, and inclusion in educational documentation? What are the childrens feelings of the documentations? In order to find answers to our questions, we used qualitative examinations consisting of seven educators and seven children from various pre-schools in Stockholm, and thereby, we have analyzed our results. As our theoretical frame, we used ourselves of Vygotskijs and Säljö's sociocultural perspective that is about "progress and learning", which is achieved by interaction and cooperation in a social context. The result shows that the aim of educational documentation is to reveal the childs development and learning, and also to involve the parents by putting up documents on the wall.

Almost all Swedes today have access to the Internet, if not through the home then via the library or work. Despite this, around 20% of the population stand outside the information society in that they lack in knowledge, assistive usability tools or positive attitude towards technology and its influence on society. The main factors influencing the digital divide in today's society are age, disability and education, while the main reason for staying outside seems to be disinterest.The question about digital inclusion is important as we now stand on the breaking-point between a society where the industry has had a prominent position for private as well as national economy and a digital society where access to the Internet is no longer about prestige, but where significant differences between users' knowledge levels can create a power gap. Gaps in access and use not only reflects already existing socio-economic conditions, but can also maintain and enhance these.It is crucial for the future expansion of Internet usage how today's non-users feel about becoming users. To understand what underlies the motivations not to use computers is one of the keys to get non-users to embrace becoming users.

Several theoretic and environmental psychological models establish a connection between the environment and the reactions of humans and the research support that there is a mutual influence between individual, environmental and behavioral factors. You often assume that a person both can influence and be influenced by the surrounding environment. This is evident, but it is less obvious how a given physical design influence people?s immediate behavior in the city. The aim of this study was to investigate if the physical design of a place influences people in an urban environment and to investigate how the behavior is influenced.

Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.

Previous research about contextual effects on advertising has mainly focused on the editorial context, while advertisements' broader context has been overlooked. This paper aims to take a broader perspective on advertisement context. Its purpose is to get an understanding on how physical exercise influence the effectiveness of print advertisements, and furthermore to look at the effects of thematic incongruence between ad and the physical environment. We hypothesize that physical exercise increase ad effectiveness through affective priming and that thematic incongruence is beneficial for ads' effectiveness, especially after training when awareness about the environment is higher. A 2×2 experiment was conducted in a gym, where each respondent was exposed to either an incongruent or less incongruent ad, before or after physical exercise.

On November 1st 2010 the obligatory audit was removed in Sweden for small companies. What factors influence such companies to have their financial reports audited, and what factors exert the strongest influence. Purpose: The authors would like to investigate factors that affect companies with voluntary audits in Skåne län to continue with the audit. The authors also wish to examine the factors that have the strongest impact on the choice to adopt auditing. Method: A quantitative study has been conducted in which aquestionnaire was sent to companies in Skåne Län Conclusion: The factors that affect smaller companies to continue with audit are as follows: Accounting quality, cost, creditors (loans), suppliers / customers, the tax office and distort competition.

The Baltic Sea, due to its special conditions, is a unique and vulnerable marine environment. There are many pressures that have an impact on the sea and one of the major problems is the extensive flow of nutrients from land. The most visible effect of the supply of nutrients is the annual algal blooms. One of the main sources of nitrogen and phosphorus supply is agriculture. Nutrient losses from arable land have been increasing as agricultural production has intensified. At the end of the twentieth century an increased awareness of these problems led to the formation of organizations such as HELCOM and Baltic 21.

This study investigates the evolution of depictions of Maoist China in Swedish history textbooks from 1970 to 2010. Through examining textbooks from this period, 20 years before the end of the cold war and 20 years after it, this study aims to investigate how quickly and how radically textbooks can change in their depictions of controversial and significant historical periods. Comparing descriptions of both people, tumultuous events, and general trends in China under Mao's rule, this study finds significant differences in how the textbooks describe Maoist China. While textbooks in the 1970s give a largely positive, sympathetic and hopeful view of China, during the 1990s and 2000s that perspective has been overtaken by an overwhelmingly critical view of Mao and his rule, focusing on his failures and dictatorial rule. The findings add to a somewhat divided field of research on the adaptability of textbooks, leaning toward the idea that textbooks can change rapidly during times of turmoil in a society..

In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

The purpose of my study was to see what kind of relationships there were between the youth and the social workers in the treatment home Hassela in Klintehamn, Gotland. The social workers work for six weeks day and night by living together with the youth. I also wanted to examine what happens when there were conflicts between them as signs of tensions in the relationships. In addition to this I wanted to study the relations between power and influence in their relationships where Hassela strives for democracy. My questions were the following; How do the youth and the staff describe the relationships between them? How do conflicts work between them at Hassela? What does the relationship between power and influence look like?The study is based on qualitative interviews with four clients and four social workers.

In subsequent to Post-colonialism the African nations have dilated into different political directions. While some nations have established well-functioning democracies, others are still under authoritarian regimes. The aim of this thesis is to examine if civil society has an impact on democratic development in West Africa. Therefore the theoretical starting point is Putnam?s theory of social capital, but this study will also examine other possible causal explanations for democratic transition.This study will be based on a comparative analysis of Ghana and Guinea.
