Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.

Ungdomsarbetslösheten har ökat på många håll i Europa som en konsekvens av lågkonjunkturen och i januari 2010 låg den i Sverige på 29,1 procent. I Schweiz har ungdomsarbetslösheten, generellt sett, varit jämförelsevis låg och år 2009 låg siffran på 8,2 procent. Examensarbetets syfte var att undersöka vilken psykologisk inverkan arbetslöshet har på arbetslösa ungdomar. En enkätundersökning genomfördes med 74 arbetslösa ungdomar i åldrarna 15 till 24 år i Sverige och Schweiz. Enkäten baserades på locus of control, self-efficacy och lycka/psykologiskt välbefinnande och ungdomarnas syn på framtiden och på livet som helhet utvärderades också.

This paper exposes the problems and challenges organizations face when integrating aged systems, web based systems and web services. The paper focuses on how people with different titles in an organization experience systems integration and the factors that contribute to project failure or success. The research methodology used in this is Grounded Theory and the resulting theory of this paper has taken form through the coding of transcribed interviews, which have gone through a constant comparing to other theories in the area of interest, mostly articles about success factors in system integration. The resulting outcome is a success model aimed to describe the underlying indicators to achieve project success.The success model consists of three factors that contribute to success in integration projects. The factors are: globalization, governance and balance.

Motivationsskapande åtgärder är avgörande för de anställdas nöjdhet inom organisationen. Vad som motiverar de anställda varierar från individ till individ. Vårt resultat visar att det existerar ett samband mellan de anställdas nöjdhet och hur väl organisationens strategi, struktur, utvärderingar och belöningar stämmer överens med olika karriärinriktningar och drivkrafter. Studien visar även att de anställdas nöjdhet påverkar kundernas nöjdhet med servicen..

The purpose of this study was to see how teachers experience their own leadership style and how they did to get their leadership to work in the classroom. The purpose was also to understand the teachers? actions, what they think is best for the students? development and how they describe the leadership in the classroom. I interviewed six female teachers and they all have had many experiences since this is their profession. My research was based on Stensmo (2000).

Idag har de flesta företag och organisationer någon form för intranät-lösning. Dessa lösningar kan vara både mer och mindre sofistikerade, men har oftast det samma syfte; att distribuera organisationens information till dess medlemmar.Denna uppsats ägnar sig åt intranät och fördjupar sig i ett begrepp som vuxit starkt de senaste åren, nämligen Content Management System (CMS). Jag fokuserar särskilt på val av Open Source CMS, för implementation i mindre organisationers intranät.Uppsatsen är ett resultat av omfattande litteraturstudier inom sitt område och bygger främst på vetenskapliga artiklar av ledande experter. Ytterligare en källa är resultatet av en enkätundersökning, som också redovisas i uppsatsen. Denna enkät hade som ändamål, att kartlägga användares attityder till deras CMS-intranät.Uppsatsens kanske viktigaste resultat är en redogörelse för hur ett moduliserad CMS-intranät skulle kunna utformas, baserad på bl.a.

Successful companies are built upon successful individuals. It is these individuals that will create, developand grow the companies and organizations of tomorrow. The primary aim of this paper is to highlight someof the key characteristics of extraordinary entrepreneurs and intrapreneurs, as well as gain a deeper understandingof what motivates them, from a time and goal-oriented perspective. Despite the importance of theseindividuals and their massive impact on society's future, there is still a lot that hasn't been investigatedregarding their entrepreneurial drive, from an academic perspective. A comparison between two groups ofindividuals was made, with a total of twenty in-depth interviews.

The Swedish system of rent control has recieved a lot of critique for creating an ill-functioning housing market. Supporters however claim that a movement towards market rents would lead to increased segregation. We evaluate whether rent control has managed to counteract segregation in Stockholm. Our evaluation is based on a data set of 292 representative households in Stockholm. We find that residents in rent controlled apartments in attractive locations typically are born in Sweden by Swedish parents and that they are likely to have a higher income than residents in rent controlled apartments in less attractive locations.

Background: Inflammatory bowel disease (IBD) is an umbrella term for ulcerative colitis and Crohn's disease. These are characterized by a chronic inflammation of the intestinal mucosa. Living with chronic illness meant that life changed significantly. Quality of life was affected for these individuals and was stressful in their lives. Aim: The aim was to describe the experiences of living with inflammatory bowel disease. Method: A qualitative literature review was chosen to analyze articles that were related to the aim of this study. Results: Based on the chosen articles five themes were created; Commuting between hope and fear, symptoms of the disease and medication become everyday focus, struggling with  the new identity, desire to control the disease- do I control my illness or does it control me and social relationships are affected. Conclusion: Inflammatory bowel disease is a distressing disease and can cause limitations in social life due to lack of knowledge by others about the disease. The affected felt a loss of control in their life due to the difficulty in managing the symptoms.

Syftet med uppsatsen är att bidra till kunskap kring investeringsbedömning av gruvprojekt och dess komplexitet samt främja diskussionen på vetenskaplig nivå kring ämnet. För att uppnå syftet tillämpas ett kvalitativt angreppssätt i form av kvalitativa intervjuer med sju gruvföretag. Slutsatsen av studien är att DCF-metoderna är de mest använda investeringsbedömningsmetoderna för gruvprojekt. Dessa kompletteras oftast med känslighets- och scenarioanalys för att ta hänsyn till risk. Metoden reala optioner tillämpas under mycket begränsade former..

To get a good economy on the dairy farms the fertility control of heifers and cows is a crucial factor. It is also important to know which key parameters that should be tracked. In this work well established routines for heat detection have to be applied. When the dairy farmers use technical aid in estrus control it is important not to forget that technical aids can not replace the human eye. Approximately 50 % of all opportunities to inseminate are missed because clear signs of estrus have not been displayed and/or recorded. The cattle fertility has been declining over recent years. During the same time the cow?s proceeds have increased, consequently applying a higher pressure on the cow and the manager.

The public health care sector has come under increasing pressure to cut down costs, maximize productivity and satisfy patients' needs during the 1990s and onwards. As a way of "getting more for less" quality management has been introduced. Originating in the private manufacturing industry, quality management has a strong focus on productivity and efficiency, aspects which are measured in quantitative terms. However, there are strong concerns that quality management is a means of speeding up the marketization of public health care by introducing core values much different from the ethic and medical norms that traditionally underpin health care organizations.This essay focuses on how quality management has been introduced to, and transformed by, public health care. A theoretical framework based on new institutionalism is constructed, and translation theories are used as a way of illustrating how the medical institutional environment, in fact, changes the concept of quality management.

Studien undersöker fem manliga gymnasieelevers upplevelse av stress och coping genom intervjuer. Respondenterna upplever att flera delar av skolan är stressande men mest så på examinationer. Respondenterna avänder olika former av coping och de som klarar skolan bäst använder en intern locus of control och problemfokuserad coping. Studenterna som misslyckas i skolan trivs inte där och använder extern locus of control och undvikande coping med betoning på socialt stöd..

Organisations and projects use CSCW/Groupware systems for collaboration purposes. These systems and applications are in many cases using a non-transparent GUI, witch is also hard to learn. This paper present a novel system that aims towards being transparent and easy to use. This system, called CollMX, will be evaluated and different ideas for future development will be presented.  The evaluation and ideas are generated by an empiric evaluation and research in different areas related to CSCW. The research does not only focus on the area of CSCW, but also extends towards the Web 2.0 and ideas about awareness..

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.
