Självskadebeteende- två unga mäns berättelser
This essay is focused on the phenomena of self-injurious behavior of two young men. The purpose of the essay is to enlighten their experiences of their earlier self-injurious behavior, and to further enlighten which factors they believe have been contributed to the origin and the ending of the behavior. The research questions the essay raises are: Which factors has contributed to the origin of the self-injurious behavior? Which functions did the self-injurious behavior have for the young men? What made the two young men quit their self-injurious behavior? The essay is qualitative and do not imply to generalize the results and it is made from interviews with respondents and earlier research on self-injurious behavior. The results show that there are differences in the factors that origin of the self-injurious behavior between the respondents.
Predation på evertebrater under tidig vår i sjön Tåkern
Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.
Monitoring lion movements
Prevention of lion predation towards African livestock is of great importance due to the economical losses farmers have because of this. Predation is also one of the main reasons for human-wildlife conflicts and lions often get killed because of it. Therefore, a pilot study using camera traps was conducted to monitor movements of lions and other wildlife through a wildlife corridor in Ol Pejeta Conservancy. The results were compared with a previous study that counted prints in the soil in front of the corridor. Due to theft risk the cameras had to be taken down and pictures were only collected from nine days.
Optimering av sampling quality-parametrar för Mental Ray
Fotorealistiska 3d-bilder används idag inom ett brett spektrum av branscher. Framställningen av denna typ av grafik kräver ofta väldigt mycket datorkraft. Vid rendering med renderingsmotorer som använder sig av raytracing algoritmer är aliasing ett medfött problem. Lösningen heter anti-aliasing som arbetar för att undvika aliasing artefakter som jagged edges eller Moiré-effekter med mera. En del av anti-aliasingprocessen är supersampling som ofta kräver mycket datorkraft.
Sverigedemokraterna i Ronneby : Teorikonsumerande studie med fallet i centrum
With varied electoral success for anti-immigration parties across Western Europe, Sweden is often held as an example where anti-immigration parties have been less successful. This have caught the interest of many scientists around the world and have recently developed theories on a subnational level when testing Sweden?s municipalities, on why they have failed here but not in other countries. But in the election to 2010, Sweden now joins the rest of the Western-European countries in having an anti-immigrations party in the parliament.This paper has tested three theories on a Municipality that has shown evident support for the Sweden democrats, both in the local and the national election. This is done with a qualitative approach, made up from interviews with the local established parties.
Arbetet inom skolan för att förebygga mobbning
My purpose in this work was to find out how staff in a middle sized school uses its local Equal treatment plan in its work against bullying. But also to see how the use of a standardized anti-bullying program works to prevent bullying. I have interviewed the principal, teachers, and what we in Sweden call a ?fritidspedagog? and the members of the anti-bullying team to get answers to my questions. The conclusion of this study is that the school follow and work according to what the Equal treatment plan states, both in terms of prevention, as in working with actual bullying cases. The school has also followed the National School Agency's recommendations on what should be the local Equality plan, but also to follow up and revise it each year. The interview shows that the staff at the school placed great emphasis on talking and discussing with students about how to behave towards each other, they also brought up things that happened at one time and talked about this. The staffs were very committed to work towards the prevention of bullying and the same was true with the school's headmaster.
Det etiska ledarskapets roll i kampen mot korruption - En studie om antikorruptionsarbete i den svenska banksektorn
Despite Sweden's ranking as one of the least corrupt countries in the world, recent studies suggest that the prevalence of corruption in the private sector is growing, now approaching international levels. Over the past couple of years, Sweden has witnessed a growing number of scandals involving unethical behavior on the part of its corporate sector. Corruption has gained the attention of authorities, legislators and the public - putting the private sector under pressure to take action to prevent such corporate misconduct. As a result, companies increasingly prioritize strategies and policies aiming to prevent corruption. This study aims to contribute to the understanding of the role of leadership in such preventive work.
Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek
The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..
Yngre pensionärers informationsbeteende i vardagslivet och på internetkurs.
The aim of this study is to examine the information behavior of younger seniors with a special focus on the Internet. Using a qualitative method consisting of a case study, including observations, diaries, questionnaires, and information diaries, we were able to compare the information behavior of the seniors in their use of the Internet, with the information behavior in their everyday life. The result of the study shows that the respondents led very active lives and used many different information sources in everyday life. They did not only seek information, but also assimilated it, often with a purpose to mediate it to other people. The motives behind the information use in everyday life were mainly connected to their life situations.
Äter Mellanskarv i Sommen det unika beståndet av röding och öring?
Detta är ett naturvetenskapligt arbete som omfattas både av en kvantitativ och en kvalitativ undersökning. Syftet med arbetet är att undersöka mellanskarvens födoval i sjön Sommen, samt att närmare studera huruvida det unika beståndet av röding och öring ingår i mellanskarvens födoval. Sommens Fiskevårdsområde har fått tillstånd till skyddsjakt på mellanskarv av Länsstyrelsen och det främsta skälet skulle vara att fågeln prederar röding och öring. Genom att analysera mellanskarvens spyboll och jämföra innehållet med referensfiskar fångade från samma sjö ska vi se om beslutet från Länsstyrelsen är befogat. Insamling av spybollar och referensfiskar utfördes i fält medan analys av spybollar utfördes på laboratorium.
Optimization of Lentivirus Production for Cancer Therapy
Vectors based on lentivirus backbones have revolutionized our ability to transfer genesinto many cell types. Lentiviral vectors integrate into the chromatin of target cells and do not transfer any viral genes causing vector replication. Both of these features arecommonly used in gene therapy and have been used clinically in individuals sufferingfrom cancer, infections and genetic diseases. It has been discovered that T-cells can be genetically modified to be used as effective weapons against cancer: therefore virus mustbe produced to deliver the gene of interest into the T-cells. In this project, lentiviralvectors have been produced to transfer the gene coding for a chimeric antigen receptor(CAR) which is directed to CD19 on B-cells.
Elitutbildning: en strategi för erkännande? - En studie om anti-diskrimineringsstrategier bland juriststudenter med ursprung i Mellanöstern
Samtidigt som svensk forskning visar att individer med utländsk bakgrund blir utsatta för diskriminering och stigmatisering så väljer allt fler ungdomar ur denna grupp att högskoleutbilda sig och visar en benägenhet att välja elitutbildningar. I denna uppsats undersöks om det finns ett samband mellan vetskapen om, eller erfarenheter av, diskriminering och elitutbildningsval. Den metod som används är semi-strukturerade intervjuer med fem kvinnliga och fem manliga juriststudenter med ursprung i Mellanöstern. De teoretiska utgångspunkterna är sociologen Erving Goffmans teori om stigma, sociologen Michèle Lamonts teori om destigmatisering och socialfilosofen Axel Honneths teori om erkännande. Resultatet visar att juriststudenternas föräldrars erfarenheter av diskriminering och egna erfarenheter av exkludering har lett till en hög studieprestation där elitutbildningsvalet kan ses som en anti-diskrimineringsstrategi.
Smärtlindring hos killingar efter avhorning :
The main purpose of this study was to investigate the effects of the non steroidal anti-inflammatory drug (NSAID) meloxicam in connection with dehorning of goat kids. Six 2-3,5 weeks old dehorned kids were given daily intramuscular injections of meloxicam (0,5 mg/kg; MG) and five age-matched dehorned kids were given isotonic NaCl (NG) for 3 days. The study was randomized and double blinded. The behavior of the kids was studied one day before dehorning, on the dehorning day and three days after. Blood samples were collected each day before the treatment and analyzed for plasma concentrations of meloxicam, hematocrit, cortisol, progesterone and glucose.
Terapeutiska antikroppar vid tumörangiogenes
Maligna tumörer är något som drabbar såväl djur som människor över hela världen. Därför
har stora ansträngningar lagts på att kartlägga mekanismerna bakom en av
nyckelparametrarna för tumörtillväxt, tumörangiogenes. Studier har visat att tumörcellerna
själva kan inducera neovaskulatur genom ökat uttryck av pro-angiogena faktorer, så som
endotelial tillväxtfaktor och angiopoeitin-2. Anti-angiogenesterapi, i form av olika
antikroppsderivat, riktar sig fram för allt mot de signalvägar som involverar pro-angiogena
faktorer i ett försök att stävja tumörens tillväxtresurser. Idag används främst monoklonala
antikroppar, var för sig, tillsammans eller i kombination med kemo- och/eller strålningsterapi.
Tyvärr är anti-angiogenesresistens är ett växande problem, troligen relaterat till både adaptiva
och inbyggda resistensmekanismer hos de tumörceller som behandlas.
Drogbudskap i antidrogkampanjer och musikrelaterad media : En kvalitativ studie om ungdomars upplevelser
Drug related messages in antidrug campaigns and music related media -A qualitative study about young people?s perceptions Youth are exposed to both promotional and critical drug and alcohol messages in their daily media consumption. The purpose of this study is to examine how youth perceive anti-drug campaigns and drug-promoting messages in music-related media. The empirical material consists of qualitative data, including a focus group and two individual interviews, consisting of youth between the ages of 18 and19. One main finding is that young people perceive anti-drug messages differently, yet they are virtually unanimous about what makes such messages effective.
