Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :
The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings.
A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce.
In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils.
The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season.
The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.
Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.
Holländska sjukan En litteraturstudie om effekterna av holländska sjukan på Botswanas textil- och boskapsindustri.
Botswanas ekonomiska tillväxt utgör ett sällsynt exempel på ett afrikanskt land som har lyckats använda sina naturtillgångar till att driva på en ekonomisk utveckling och samtidigt minimerat effekterna av den så kallade Holländska sjukan (HS). HS är ett ekonomiskt fenomen som går ut på att en växande sektor som baseras på naturtillgångar skadar landets tillverkningssektor och leder därmed till en indirekt de-industrialisering. Botswanas diamantindustri står för drygt 35% av BNP:n och hela 75% av exportintäkterna vilket gör att landet har en mineralbaserad ekonomi. Detta faktum har gjort landet väldigt intressant för forskning. Aktuell forskning har med hjälp av ekonometriska metoder visat att landets tillverkningssektor har undvikit eller drabbats minimalt av de effekter som HS utgör.
Likhetsteorin : En teoretisk utveckling av Collins interaktionsritualer
Uppsatsen utgår från upptäckten av ett mönster i Collins teori om interaktionsritualer. Mönstret består i att flera av idéerna och begreppen som används i Collins teori kan förstås som upplevelser av likhet mellan de samspelande individerna. Baserat på upptäckten av detta mönster formuleras uppsatsens syfte. Syftet är att utveckla grunddragen till en ny teori om interaktionsritualer som förklarar interaktionsritualer utifrån individers upplevelser av likhet. För att uppfylla syftet diskuteras fyra aspekter av interaktionsritualer.
Biblioteksassistent: En yrkesroll i förändring
Little attention has been paid in the literature to libraryassistants in Swedish public libraries. In this bachelor thesis,the professional role, work duties, career prospects and statusof library assistants are examined at two public libraries.Because of a scarcity of published information on thedevelopment of this profession in Swedish public libraries,retired library assistants, as well as currently employedlibrary assistants, librarians and a library head wereinterviewed.Since the ?80s, work duties of library assistants havechanged, with a reduction in some of the more manualaspects of library work, the development of new duties and,overall, an increasing similarity in the duties performed bylibrary assistants and librarians.Additionally, the public perception of library assistants as acategory distinct from librarians was investigated bydistributing questionnaires to library patrons. Contrary toexpectations prompted by statements in the literature, asubstantial portion of visitors was found to be aware of thetwo separate categories.Library assistants at Swedish libraries have no careerprospects, unless they undertake studies in their own freetime and at their own cost, and obtain a librarian degree. Adifference between the situation of library assistants inSweden and corresponding professional categories in a fewother countries is that, at present and for several years, noformal education for library assistants has been available inSweden.
Local poultry production in rural Zambia and the effect of light on poultry performance
Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production.
Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.
Effekterna ligger i betraktarens ögon - En studie om effekter av videopresentationer inom e-handeln
Companies within the e-commerce industry currently try to overcome the disadvantages of not being able to provide a physical inspection of products, and this is especially an issue for the apparel industry. One way of trying to overcome this issue is by presenting apparel with a short video of a model wearing the garment. The aim in this thesis is to investigate how these video presentations affect consumers' emotions, cognitions and intentions. Since previous studies have found that different shopping scenarios can moderate the effect of stimuli in the atmosphere on the consumers' emotions, we also aim to see if a video presentation, depending on the shopping scenario, could have a negative impact on site visitors. Moreover this thesis investigates the moderating effects of involvement on consumers' cognitions.
Jämställdhets- och föräldraledighetsregler : -regelverkens samverkande effekt för ett jämställt arbetsliv
The legal right to take time off from work to care for one`s children has been regulated in Swedish law since late 1930. This right was limited to mothers and was provided under restricted forms. There was a long qualification period and the length of parental leave was limited.Since then, the right to parental leave has been extended through several modifications of the law. The question of equality in both the labour market and the private sector has been one of the greatest forces behind these changes. By including men in the right to take parental leave, the work place has become more equal and it is now considered a natural part of the employee?s life to request time off to care for children.Labour Arbitration Court has shown through its case law that equality in the work place is of the utmost importance and has shown its support in this matter through its judgements.
Lilla Hjärtat och alla små brokiga bibliotekarier ? En studie av hur Lilla Hjärtat hanterats på folkbiblioteken
This bachelor's thesis is an investigation into the public libraries'actions following the debate of Stina Wirséns character LillaHjärtat, featured in picture books and films for young children.The character was accused of being racist, due to its similarity tostereotypes such as pickaninnies. Because of this, the books'existence in public libraries was questioned.The purpose of this study is to investigate how librarians havedealt with these books, and what they have based their decisionson. To explore the background of these decisions we have usedPatrick Wilson's theory of cognitive authority (1983). We haveexamined which cognitive authorities have been used in thedecision-making process of how to handle the books containingLilla Hjärtat, and why these cognitive authorities have beenchosen. The method used in the study is qualitative interviewswith seven librarians working in public libraries throughoutSweden.The results of the interviews show that the librarians? mostprominent cognitive authorities have been authors and illustratorsof children's books.
Effekt av spädningsvätska på spermiemembranintegritet analyserad med NucleoCounter SP-100 :
This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality.
In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.
Rumsligt koncept som sto?d fo?r rundvandringar : En studie av flo?den och processer pa? Alfa Laval i Eskilstuna
AbstractThis study deals with the tours carried out in the manufacturing sector, at Alfa Laval in Eskilstuna. A large number of visitors, from a variety of backgrounds, go there to see how the manufacturing of separators works. With visitors I refer to the company?s customers, suppliers, students, in- house trainee courses, managers and senior citizens groups.The study examines how these tours can be standardized using spatial design. The result shows the importance of working systematically with visualizing the work as well as the environment for optimizing the visitor's understanding.
Thinking more like a client. : Designfaktorer som påverkar valet av tjänsteföretag.
Companies in the western world can no longer compete by using traditional means such as product and price since the commerce of services continually grows. To avoid similarity and increase competitive advantages modern companies have to be more specified. The competition between companies has increased and customers are harder to reach. Customers of today can afford luxury but trend indicates that originality, identity, and status are more important than factual needs. Products created and consumed at the same time within the service market are often very homogenous (similar).
Sociala och emotionella interventioner i skolans värld. : Vad händer med karaktären hos eleverna?
The purpose was to investigate whether using two type of interventions (i.e., Four rooms of change in school and EQ- workshop) in addition to curriculum guidelines can affect character development in children 10-12 years of age. The data was collected using the test Junior Temperament and Character Inventory (J-TCI; Cloninger, CR, 1994) in three elementary schools among students in fifth grade who had been involved in any of the two interventions for the past two years or no intervention at all.The J-TCI scales were used to, besides the seven personality dimension it measures, create a self-constructed empathy scale. A total of 55 participants were included in the study (girls n = 26 and boys n = 29). Statistical testing with MANOVA showed no significant main effect on empathy or any personality trait. There was however an interaction effect between intervention and gender on the character traits.
Örter som fodertillskott till häst : populärt komplement utan risker?
In the Swedish market, there is a wide selection of herbs as supplement to the horse´s feed. A trend today is that many companies are marketing herbal remedies with allegations of medical effects. If you want to sell the product for that purpose it must be verified and approved as drug or natural remedy by the Medical Products Agency. Some herbs may contain active substances. Nevertheless, only a few studies have been conducted on single herbs to investigate safe doses for horses.
Vikten av ett välskött arbetsklimat: En kvantitativ studie av arbetsklimatets påverkan på ekonomiskt resultat
The well-being of employees has become a key concept in the rhetoric of the company boards and business literature of today. There is however not much statistic evidence of a connection between economic results and the perceived working climate. This thesis sets out to investigate whether there is a positive correlation between economic results and working climate on a work group level. It also aims to study which specific working climate factors influence the results. In order to meet its purpose this thesis analyzes employee satisfaction questionnaire data and economic results from more than 300 work groups.
