Det emotionella valet - ett alternativ och komplement till rationaliteten
The purpose of this thesis is to evaluate and develop a useful theory of human behavior that recognizes the importance of our emotions. The new framework, called the theory of emotional choice, is developed by a holistic method in which results from the fields of psychology, sociology and (neuro-) biology are used to mutually support the conclusions. The theory is distilled into six preliminary points, which are based on the finding that we are not thinking as logical, rational and longsighted as is often assumed. Instead the regular human thinking is suggested to be shortsighted, intuitive and ruled by our emotions and our needs for generality, causality and normality.To demonstrate the usefulness of the new framework, it is used in an analysis of financial bubbles. Additionally, the fields of negotiation, election and ethics are suggested as potentially interesting to analyze with the new theory..
Daglilja : en studie av växtslaget, handelskedjan och sortimentet
This thesis describes the genus Hemerocallis, the trading with daylily from hybridizer to seller with emphasis on the Swedish market. The first part describes the daylilies biology its botany, breeding, production, pests and diseases. Also the tobacco ringspot nepovirus recently confirmed in Sweden is described. Since the breeding of daylily is mainly done in Florida topics like hardiness and influence of the climate are included. The first part is mainly based on literature studies, but also interviews with growers and breeders from Sweden, USA, Holland and Germany.
Populationsstruktur och genetisk analys av exteriöra egenskaper hos svensk ardenner :
The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population. Additionally, a breeding scheme proposal was created, based on the results achieved in the study.
The data studied were obtained from the Swedish Horse Board and from the Swedish Ardenner Association. The data included 1632 three-year-old horses, mainly mares, and 356 stallions, judged between 1986 and 2005 at conformation shows. The traits studied were type, head-neck-body, legs, walk and trot at hand, total score and height at withers.
Populationsdifferentiering hos kransalger
Kransalger är en viktig nyckelart i Östersjön. De förökar sig med hjälp av oosporer och denna studie har syftat till att urskilja morfologisk differentiering mellan oosporer inom och mellan individer och populationer. Främst ställde jag mig frågan huruvida skillnader och likheter i morfologi kan associeras med skillnader mellan olika geografiska avstånd och habitat samt i vilken mån oosporer kan återföras till korrekt population och individ. Kransalger av arten Chara aspera har insamlats på lokaler i östra Svealand och elliptiska Fouriertransformationer har använts för att med hjälp av vågfunktioner beskriva oosporernas konturer. Parametrarna i vågfunktioner har sedan använts för statistiska analyser.
Spelberoende i Västra Götaland, kommunernas inställning till ansvar, hjälp och egen kunskap.
The aim of this essey was to find out what kind of help problem gamblers can get at social service offices in the region Västra Götaland in Sweden. We also examined the knowledge regarding gambling problems at social sevice offices and who the head of the social service offices regarded having the responsibility for the question of helping problem gamblers. As a last question we wanted to know if the size of the population in the community had an impact on these questions. Central questions in our essey asked are:How much help does the social service offices in the region Väsra Götaland offer problem gamblers? Who has the responsabilety to help problem gamblers according to social service offices?What knowledge does the social service offices have concerning problem gambling?Does the population of the community have an impact on theese questions?This is a quantitative study made as a webbservey to the head of the social service offices in the region Västra Götaland.
Surveillance of Geomyces destructans in Swedish bats and Bat Hibernacula
White-Nose Syndrome, WNS, is an emerging fungal disease in the Northern American bat population causing mass mortality in infected hibernacula. Geomyces destructans is a newly discovered psychrophilic fungus causing WNS but the pathogenesis and epidemiology of the disease is not yet fully clarified. Geomyces destructans has been found in Europe but has not been a cause of mass mortality there. This study is the first investigation done to see if G. destructans is present in Sweden.
Med hunden i fokus - en metod att identifiera hundars användningsområde utifrån det postkraniala skelettet
AbstractThis is a study of present day dogs with the purpose to establish a method to investigate archaeological dogs and determine their use in the past. The study has focused on measurements of five bone elements, scapula, humerus, radius, ulna and femur. A principal component analysis has been applied in order to decide which measurements to be further used in the analysis. Different proportions have been calculated on these measurements.A test to try the method has also been done on bones of a wolf and a dog without known background. The results from the different elements are positive, and they narrow the field down to two dog types of which one is more likely to be true than the other.The final results show that, although over lapses between the four different dog groups; hunting dogs, guard/work dogs, sled dogs and shepherd's dogs exists, it is possible to distinguish different dog usage from the proportions of the bones..
Stadsrum och stadsliv - Bebyggelsestrukturers inverkan på kvalitet och innehåll i det offentliga
ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.
Klassificering av allvarlig kronisk parodontit: En jämförelse av fem olika klassificeringar utifrån prevalensen av allvarlig kronisk parodontit i en population från Kalmar län
Bakgrund: Parodontit definieras som en inflammationssjukdom orsakad av en obalans mellan bakterier i den dentala biofilmen och värdens immunförsvar. Det saknas en enhetlig klassificering för allvarlig kronisk parodontit i epidemiologiska studier; internationell data avseende prevalens och utbredning av kronisk parodontit är därför svårtolkade. Det saknas studier som har undersökt huruvida och hur mycket variationerna av klassificeringar påverkar utfallet, det vill säga prevalensen av allvarlig kronisk parodontit.
Syfte: Syftet med studien var att utvärdera skillnaderna mellan fem olika klassificeringar av allvarlig kronisk parodontit: (i) Konsensuskonferensen 1999, (ii) American Academy of Periodontology and Centers for Disease Control and Prevention (AAP/CDC), (iii) European Federation of Periodontology (EFP), (iv) Jönköpingsstudien samt (v) Skånestudien.
Material och Metod: För att kunna jämföra klassificeringarna studerades prevalensen av allvarlig kronisk parodontit utifrån en population i Kalmar län.
Begåvningsnivå och psykiska problem - en undersökning av en kohort tvångsvårdade flickor och kvinnor
This study describes the intellectual ability of a cohort consisting of 120 young women in compulsory care at a SiS institution in Sweden, tested and analyzed between January 2001 and May 2005. The women have been tested with the intelligence tests WISC-III or WAIS-R, as well as the personality trait tests BCT, CMPS and SCL-90, and the personality disorder test SCID-II. This material has been analyzed to investigate how these women's intellectual ability relates to other factors. The analyses show that the main difference between the women of this study and the normal population is their level of intelligence and presence of personality disorders. The IQ level of these women is statistically proven on an average one standard deviation lower than the normal population.
Förskola med eller utan ämnesspecifika samarbetspartners.
Mitt syfte med examensarbetet är att undersöka om en samarbetspartner med speciella ämneskunskaper ger bättre förutsättningar för förskolan att kunna erbjuda förskolebarnen olika ämneskunskaper, än förskolor med förskolepedagoger. Jag valde att titta på ämnet biologi genom att göra observationer i tre olika förskolor samt intervjua två pedagoger på varje förskola. Resultatet är att förskolorna skiljer sig åt i vad de erbjuder barnen inom ämnet biologi, men om det beror på om de har samarbetspartners eller inte gå inte att fastställa av enbart den här undersökningen. Flera faktorer som förskolans miljö, vilka som jobbar på förskolan samt barnens intresse påverkar också. Men undersökningen visar att verksamheten påverkas av att ha samarbetspartners.
Äldres erfarenheter av aktiviteter i ett socialt sammanhang. En narrativ studie om den åldrande människan
There is no general aging process therefore should health efforts directed at elderly population based on each individual as a unique person with specific needs. When aging becomes a fact not generally decrease the lust and the desire to be active but it is perhaps more about the body's ability to keep up on what the head wants. Therefore the range of activities towards the elderly population requires some adjustment that can partly be achieved by taking some of the older people?s experiences. The purpose of this study was that by the older people?s experiences of organized activities in a social context to illustrate how they perceive their participation.
"Folk är inte lika för att dom kommer från Sudan" : en översikt av förekomsten av familjer med annan kulturell bakgrund vid Familjenheten i Lund
The purpose of this study was to, using statistical analysis, investigate to what extent families of a different cultural background have participated in family therapy and other family treatment programs at Familjeenheten in Lund. With questions regarding the goals of treatment, and the importance of cultural competence in the treatment process we have let two unit managers comment on the statistics. The population of the study is too small to allow general conclusions to be drawn, however, we have been able to ascertain that families of a different background are over-represented relative to their percentage of Lund´s population. Familjeenheten has no statistical record of ethnicity and the interviewed persons express no certain importance in the families´ cultural origins. They express no need to develop special treatment methods that take the clients´ cultural background in regard as they feel that so many of family issues are universal.
Identifikation av icke-representativa svar i fra?geunderso?kningar genom detektion av multivariata avvikare
To United Minds, large-scale surveys are an important offering to clients, not least the public opinion poll Va?ljarbarometern. A risk associated with surveys is satisficing ? sub-optimal response behaviour impairing the possibility of correctly describing the sampled population through its results. The purpose of this study is to ? through the use of multivariate outlier detection methods - identify those observations assumed to be non-representative of the population.
Sexualitet och idealbilder : Unga tjejers syn på attityder och normer kring kvinnlig sexualitet
The purpose of this thesis is to find out how young girls reason about norms and attitudes towards female sexuality. Through a qualitative research approach ten girls in grade 9 has discussed in two focus-groups on what is typically female, the ideal images of the ultimate woman as well as what is considered to be characteristic of female sexuality. The results were analyzed using Tina Mattson's theory of intersectionality, Beverly Skeggs theory of respectability and Göran Burenhults thoughts about biology and sexuality. Some of the main findings are that the girls in the study associate femininity primarily with external attributes and beauty and the ideal image of the woman is beautiful, yet independent. Further they describe different conditions for boys and girls to explore their own sexuality, and also that for girls the risk of being branded a "whore" is ever present.
