Kålgallmygga, Contarinia nasturtii Kieffer : en växtskadegörare på kål
The purpose of this paper is to examine what problems cabbage growers have with the
Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become
a larger problem for cabbage growers in several countries in Europe as well as in
Sweden. In Canada the problems are so severe that the midge is classified as a
quarantine pest and therefore certain rules have to be followed. I have collected facts
of the biology, host plants and reproduction of the Swede Midge, as well as the
growers experiences and the occurrence of the midge in Canada, Europe and Sweden.
The Swede Midge is hard to control because of its short life cycle and the larvae are
protected between the heartleaves of the plant. When the larva feeds on the growth
point the plant becomes distorted, in some cases several heads develop or none at all.
When the midge infests spring rape its flower buds become undeveloped and rosette
like.
Pensionärspooler : Pensionär med fortsatt anställning efter ett yrkesverksamt liv
A qualitative survey has been carried out in a manning company whose business concept was to employ pensioners. Six pensioners have been interviewed regarding their views on resumed employment. The results of these interviews have been analysed supported by analytic induc-tion. Areas investigated cover: promotion of better health through work, motivation factors, groupings and control, experience and learning, work and spare time and finally strategies that appeal to an older workforce.The purpose of the survey was to investigate whether the manning company utilizes pension-ers? experience and work skills from their former working life.
Politiska beslutsprocesser som reformer -Exemplet Skånsk Livskraft
Arbetet syftar till att förstå en fundamental offentlig reformprocess, och fokus ligger på den politiska beslutsprocessen bakom förändringen av sjukvården i Region Skåne. Vi gör en kvalitativ fallstudie av projektet Skånsk Livskraft, och genomför intervjuer med potentiellt inflytelserika politiker och tjänstemän. Den teoretiska tolkningsramen utgörs framförallt av Institutionell teori samt Garbage Can.Tidsperspektivet visar hur tidigare misslyckade reformer möjliggjort tillblivelsen av Skånsk Livskraft. Vidare har arbetssättet, med stark yrkesmässig förankring, gett tjänstemännen en inflytelserik roll. Enigheten över blockgränserna vid budgetförhandlingen 2001 var en förutsättning för att projektet skulle kunna konkretiseras.
Det narrativa greppet om erkännandet: En studie i hur makt förmedlas genom berättelser
I denna uppsats utforskas det narrativa perspektivet som ett möjligt analytiskt grepp för att komma åt maktstrukturer, där erkännandet av identiteter analyseras som en upplevd domän av dominans. Uppsatsen inleds med en utveckling av begreppet diskursiv makt, vilket görs genom användande av Steven Lukes teori om maktens tredje ansikte. Följande därpå diskuteras hur man med hjälp av det narrativa greppet kan förstå makten som reglerar berättandet av jaget. Denna makt ses som påvisad då teman i metanarrativ och framträder som reproducerade i konkreta narrativ. Resonemanget klargörs genom en diskussion om republikanismen som ett metanarrativ, vilket relateras till hur maktutövning genom erkännandet kan ta sig uttryck..
"Kärringsjuka?" Att leva med Fibromyalgi
Bakgrund: Fibromyalgi drabbar två till tre procent av befolkningen och är ett kroniskt smärttillstånd utan känd orsak. Majoriteten av dem som drabbas är kvinnor. Sjukdomen syns inte utanpå och det finns därför en risk att drabbade blir missförstådda av människor i sin omgivning och av sjukvårdspersonal. Syfte: Att med den här litteraturstudien beskriva hur kvinnor med fibromyalgi upplever sin livssituation. Metod: En litteraturstudie baserad på elva kvalitativa vetenskapliga artiklar.
Det dubbla uppdraget: relationen mellan INGO och staten i Vietnam
Due to the political system in Vietnam, all organizations in Vietnam need a permit to operate in the country and consequently, have to balance their mission, their main purpose of being in the country, with the fact that they are dependant on the government to give them the permit they need to stay in the country.With this as our basis, the main focus of this essay has been to identify different types of relations that exist between the Vietnamese state and International Non Governmental Organisations (INGOs) in Vietnam. Since we have interviewed people representing INGOs, our result is based on their experience of this relationship. By using Najam's Four-C's Model, we established that the more traditional INGOs which principally provide services, predominantly have a cooperative relationship with the state, whereas radical INGOs which are committed to policy change, mostly have a relationship which is characterised by conflict..
"Jag är bättre än så" : En studie om hur stimatisering- och stämplingsprocesser kan påverka föredetta kriminella mäns anpassningsmöjligheter i samhället.
ABSTRACTThe aim of this study is to look into how ex-offenders experience that stigmatization and labeling- processes might affect their possibilities to create an integrated and adapted life in society. It is also of interest to study how and if the interviewees experience their self-image to be affected by these processes. Our research-questions are:- How do ex-offender males experience stigmatization and labeling-processes to impact their possibilities when trying to re-integrate into society?- Do ex-offender males experience their self-image being affected by stigmatization and labeling-processes? If so, how are they affected? In order to achieve this we interviewed members of the organization KRIS in Örebro, where we selected males over 23 years of age with a prior prison sentence. The study is based on the labeling-theory of Howard Becker as well as the stigma-theory by Erving Goffman.In the conclusions derived from the results we found that the interviewees experience a more distinct and obvious stigmatization and labeling from authorities such as the police and the legal system, than that from other people in society.
"På gränsen till duktig?" : En studie om delaktighet och självbestämmande för personer med insatsen bostad med särskild service enligt LSS
In this study we have aimed to explore how participation and self-determination is implemented in the daily life of disabled people who receive support through LSS. The questions addressed concern possibilities/obstacles for the participation and selfdetermination of disabled people who live in group housings, and how the terms participation and self-determination are realized. Nine interviews have taken place with staff members and directors of different group housings. We have found that the interviewees believe that the nature of a person?s disability can be a barrier to the individual?s self-determination and participation in his or her everyday life.
Utvärdering av rörelsemönster hos öring (Salmo trutta) utifrån otolitmikrokemi
The classic view of trout (Salmo trutta) life history is that trout begins its life in freshwater, migrates to the ocean after about 1-4 years and then returns to freshwater to spawn. As trout fry have been caught at the mouth of the River Emån, near the Baltic Sea, researchers have speculated that some trout emigrate during their first year of life. The purpose of this study was to describe the variation in the length of time trout reside in freshwater before they migrate to the ocean for the first time. Another purpose was to investigate whether it was possible to discern where and how long the fish spent in freshwater and saltwater during different parts of their lives. Between 2007 and 2009, 23 adult trout were captured in the River Emån in southeastern Sweden.
Hur kan en familjs livskvalitet påverkas då ett barn har födoämnesallergi?
Bakgrund: Nästan vart fjärde barn i Sverige har idag en allergisjukdom med symtom. Att som barn få diagnosen födoämnesallergi har en påverkan på både barnets och hela familjens livskvalitet. Syfte: Syftet med studien var att belysa hur en familjs livskvalitet kan påverkas då ett barn har födoämnesallergi. Metod: Studien baserades på sju vetenskapliga studier, både kvalitativa och kvantitativa. Resultat: Efter att ha granskat studierna framkom tre genomgående teman; upplevelser av oro och rädsla, upplevelser av bristande stöd och information och begränsningar och strategier i det dagliga livet.
Effekten av klimatförändringar påkontrollbehovet av åkerogräs
With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.
Vilken roll spelar kulturen : En retorisk studie av debatten efter mordet på Fadime
Uppsatsen handlar om svenska tidningars debatt efter mordet på Fadime Sahindal 2002. Hon sköts till döds av sin kurdiske far som tyckte att hon fläckat familjens heder. Mitt syfte var att ta reda på hur debattörerna såg på den kurdiska kulturens roll i sammanhanget. Jag valde ut åtta debattartiklar som publicerades i Sveriges största morgon- och kvällstidningar den första tiden efter mordet. Artiklarna var skrivna av åtta olika skribenter, fyra män och fyra kvinnor med både svenska och kurdiska bakgrunder, som alla haft nyckelroller i debatten.
Neuropsykologisk studie av benign barnepilepsi med centrotemporala spikes
Benign Childhood Epilepsy with Centrotemporal Spikes - BCECTS is a common neurological syndrome but the possible cognitive effects are still relatively unknown. In the study 12 children with the diagnose BCECTS, 9 boys and 3 girls between the ages of 5,5 and 13,5 years, were examined. An extensive battery of neuropsychological tests were administered. The results indicates normal cognitive functioning as compared to the normal population, with one exception; an aspect of attention. But the results also indicate several negatively effected performances when compared to the cognitive g-factor of each child.
Review of the litterature and an attempt to evaluate intake levels of iodine and selenium in dogs with and without lymphocytic thyroiditis
The prime aim of this thesis was to investigate whether high or low iodine intake during certain periods of life was, or was not a strong risk factor for the development of canine lymphocytic thyroiditis (CLT). And secondly, if a high or low selenium intake in a combination with high or low iodine intake also may have an influence on that risk factor. To investigate this, a dietary questionnaire was sent out to dog owners. The dogs were selected from an ongoing genetic study of CLT. The questions investigated brand and type of feed during different life stages (puppy, junior and adult) and also if there were any use of dietary supplements.
Agila metoder: Vad får människor att ticka? : En studie kring projektdeltagres inner work life
Författare:Elin Larsson och Ida Persson, studenter vid Magisterprogrammet i Projektledning vid Karlstads universitet.Bakgrund: Agila metoder är ett samlingsnamn för ett antal processer främst inom mjukvaruutveckling, men även för projektledning (Cervone 2011). Detta arbetssätt kom under mitten av 1990-talet som svar på en önskan om ett mer flexibelt arbetssätt och intresset för dessa metoder har ökat markant de senaste åren (Lindvall et al. 2002). I en omfattande studie kring bland annat motivation har Amabile och Kramer (2011) definierat termen inner work life som de processer som tillsammans bearbetar de intryck som en person får utifrån arbetsdagens händelser. Beroende på hur dessa händelser påverkar personen presterar denne mer eller mindre bra på sitt arbete.Problemdiskussion: Enligt Tessem och Mauer (2010) har allt fler organisationer börjat använda sig av agila metoder med ett gott resultat på deltagarnas känsla avmotivation.
