Differences in host plant preferences and olfactory physiology between populations of the moth Spodoptera littoralis established in Egypt and Benin
This study was made to compare and distinguish any differences in olfactory recognition and
host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The
populations used were established in Egypt and Benin, Africa. The documentation consisted of
information about (1) each of the strains development through the larval stage up to pupation on
diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton,
clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any
possible responses to plant volatiles.
Throughout the diet experiments the larvae from the Benin strain showed significantly a better
development between artificial, clover, cowpea and cotton respectively, while the Egypt strain
had significance between artificial, cotton and cowpea/clover as diet.
Also noted was how the strains substantial development of weight differentiated if fed the cotton
diet, followed by the cowpea diet showing that the Benin strain would develop a higher body
mass on a cotton diet as well as on a cowpea diet.
This trend was however switched once the pupal stage was reached, where the Egyptian strain
contained a significantly greater body mass than the Benin strain on the artificial and the Benin
strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly
better on cowpea while the Egypt strain develops better on an artificial diet.
During the oviposition experiment that both stains showed a clear difference in hierarchy of host
plants considered suitable for oviposition, where the Egyptian strain is significantly more
attracted to clover than the Benin strain.
Also showed with electroantennographic recordings and significant values was the higher
sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate,
Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..
Attityder till implementering av precisionsodlingsteknik :
Different techniques for precision agriculture have been available during the last decade.
Some of them are more widely used than others. The main purpose of this thesis was to
investigate the different attitudes to precision agriculture that exists among farmers and
advisors in Sweden.
Eight advisors and sixteen farmers were asked for their opinion of a number of specific
techniques for precision agriculture, such as yield-mapping, precision liming, the Yara
Nitrogen Sensor and site-specific fertilization with phosphorous and potassium. They were
also asked to describe the way in which the counselling in Swedish agriculture is used and
also about it's importance for the adaptation of new techniques.
The high costs are mentioned to be one of the most important reasons why precision
agriculture hasn't been more widely spread. Several farmers refer to their farms as too small to bear the costs that come with the techniques. The individual interest for technique among the potential users plays an important role.
Vikten av motivation på arbetsplatsen : en studie om belöningssystem i hotellbranschen
Background:Companies are beginning to see the world as their market; not only to seek global opportunities but also to oversee the global competition. Although most people connect globalization to export and import of goods, the globalization process also affect the businesses distinguished by service. The corporations are faced with higher demands of adaptation, which in turn leads to higher needs of skills and knowledge, which of course is very important in business such as the hotel industry. A motivated employee can perform better and furthermore has a stronger sense of belonging to the organization and might therefore be a key to future success of the company.Purpose:The main purpose of this essay is to compare the motivation strategies and reward systems chosen by the management and match this with what the employees are requesting. By doing this we can compare the different objects studied in this essay and furthermore we will be able to see which hotel that has the best match.
Trapphus i träplattform för CBBT
Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.
Försäkringskassan har beslutat : En undersökning av mottagaranpassning och språkbruk i Försäkringskassans beslutstexter
The aim of this study is to learn about and demonstrate the process in which Försäkringskassan (The Swedish Social Insurance Agency) customizes texts and the texts linguistics influence on a potential beneficiary. I use three different questions to fulfill the purpose of the study. I examine what the manuals writers of Försäkringskassan use say about the issues of sentence length, addressing the beneficiaries and wording ? three language features that represent different perspectives within plain language research. Furthermore, I examine how decision texts are created and tailored for its beneficiary group and how the language in decisions is perceived by potential beneficiaries.
Stöpt i kulspruteolja en litteratursociologisk studie av den unglitterära tidskriften 40-tal och dess idéklimat.
This masters thesis is a study of the ideas brought forward in the literary magazine 40-tal. The methodology involves the adaptation of a literary sociological perspective where the ideas of the young literary avantgarde in the magazine 40-tal interplays with the established philosophy of the Swedish society during the period 1944-47. The main purpose has been to examine 40-tal as a product of supreme individuality that originates a unique climate of ideas which exceeds the involved collaborators individual writings. I have thereby related my analysis to the Marxist oriented theories of Raymond Williams. This has been done in order to see how the external pressure of the social structure and the market acts together with the internal pressure of keeping up with the times and how this affects the individual authors and the process of creating.
Effekter av investeringsstödet i miljö- och landsbygdsprogrammet för perioden 2000-2006 : en studie på företagsnivå
Investment aid is a part of the Rural Area Programme, which contains support to Swedish agriculture and the countryside. There is a new programme every seventh year and SLU (Swedish University of Agriculture) has the mission to perform the evaluation of the previous programme, which lasted between 2000 -2006. The investment aid's aim is to support investments that, among other things, support the adaptation or conversion to more environmentally friendly production methods, improves the product quality, develops new or complementing activities, and improves the environment and the animal- and working environment. The question is if it's only money that matters for these kinds of investments to be done and what has happened with the money that was paid? This thesis investigates how the investment aid has affected the receivers.

Tillfrisknande och användning av hästar med fång :
Laminitis has crippled horses through times and many cures have been used to
treat it. Since the mechanism of the disease is yet not fully understood, treatments
are only ways to alleviate the pain and at best, slow down the pathological process
enough to make time for improvement. This paper is a retrospective study of 71
horses treated by a protocol at Hästsjukhuset Strömsholm. The protocol implies
three visits at zero, five and fifteen weeks. At each the horse is evaluated and
treated by a veterinarian.
God arbetsmiljö för personer med Aspergers syndrome: : En integrativ litteraturstudie
Sammanfattning Syftet med denna intervjustudie var att undersöka huvudhandledares och kliniskt utbildningsansvarigas uppfattning om undervisnings- och handledningssituationen på en anestesiklinik. Totalt intervjuades 6 huvudhandledare och 5 kliniskt utbildningsansvariga. Intervjuerna transkriberades och analyserades utifrån en fenomenografisk ansats enligt Starrin & Svenssons (2007) analysmetod. Huvudhandledaruppdraget uppfattades som att befinna sig i en oförutsägbar situation och en svårbedömd undervisningsmiljö, vilket ställde krav på noggrann planering och tydlig kommunikation, samt lösningar genom kompromisser. Huvudhandledarna uppfattade även att de hade en övergripande stödjande funktion gentemot överbelastade handledare, utsatta studenter och nyanställd personal.
Att påverka sina preferenser: en analys av rationalitet och preferensdynamik (v 1.1)
Actors deliberately change their preferences, contrary to the assumptions of rational decision models. This study shows why, and to some extent how. Preferences are necessarily ambiguous and unstable. Rationality is a regulating myth which has had a profound influence on Western conceptions of what an actor is.The aim of this study is to help individual actors understand the theoretical grounds of their actions. The analysis provides tools for examining decision methods and preference changes.
Medicinen är kryckan, inte lösningen: personals upplevelser av de psykosociala inslagen i läkemedelsassisterad underhållsbehandling
The meaning of the concept of psychosocial treatment is ambiguous. The purpose of this study was to examine how professionals within some care institutions, which provide methadone, buprenorphine or naloxone treatment, regard and carry out the psychosocial features of such treatment. Central issues discussed were; how personnel approach the psychosocial features of the treatment, what personnel regard as a focus in the psychosocial treatment, what conditions personnel consider affect treatment positively in order for it to be successful and how personnel see the relation between the medical and psychosocial features of the treatment. The method used was interviews with nine professionals in six qualitative interviews. The theoretical perspectives and concepts used in our analysis were; the theory of biological dependence, an organizational perspective, Prochaska and DiClemente's Stages of Change Model, the concept of individual reality and the concept of marginal conflict.Results show that the conditions most important for successful treatment are; that the patient has a place to live, an occupation, motivation, that the patient take responsibility for his/hers progress and have realistic expectations about the effects of the medicine.
Bankernas bedömning av lantbrukskrediter : en jämförelse mellan olika branscher
