Relation möter rationalitet: Om professionalisering av inköp av managementkonsulttjänster
The purchasing of management consulting services has traditionally been characterized by informal and relation based interaction. However, case studies have shown that there is a movement towards more formalized and structured purchasing procedures among buyers of management consulting services. The purpose of this study is to investigate the prevalence and the implications of this professionalization. To investigate to what extent certain mechanisms of professionalization have been implemented on the Swedish market, a survey directed to Sweden?s 500 largest companies was conducted.
Resultatmanipulering: En studie av förekomsten av resultatmanipulering i svenska företag
The aim of this thesis is to examine the existence and prevalence of earnings management in Swedish companies. Theoretical frameworks often suggest that there are strong incentives to practice earnings management. The research area of earnings management has, to date, mainly focused on detecting earnings management. However, to our knowledge, no such studies have been conducted on Swedish companies. This thesis provides evidence of the existence and prevalence of earnings management in Swedish companies.
Magsår hos gris : förekomst och faktorer som påverkar
Gastric ulcer is a common disease among pigs in the whole world where an intensiveproduction occurs. It is mainly the upper region, the nonglandular region of the stomach thatis affected. Gastric ulceration is a disease with several risk factors. The factor that seems tohave the largest impact on the development of gastric ulceration is a small particle size of thefeed. The reported prevalence of gastric ulceration differs from 5 to 100 % and it is a largeherd-to-herd variation.
Utsöndring av klamydia från kliniskt friska katter :
Blood samples from 44 clinically healthy cats were analysed for the presence of antibodies to Chlamydophila felis. As we wanted to investigate if the antibody titre of clinically healthy cats correlates to shedding of chlamydia, conjunctival and vaginal or preputial swabs respectively, were taken and analysed with rtPCR (real-time polymerase chain reaction) for the presence of chlamydia DNA. Furthermore, to investigate possible epidemiological factors connected with asymptomatic cats infected with chlamydia and to see if there were any indications that chlamydiosis can cause reproductive problems, the owners of the cats were asked questions regarding this. Sixty-one per cent (27 of 44) of the cats were seropositive. Three of these (11 %) had the highest antibody titre (1:1600).

Diagnostiska metoder för växtvirus i nematodvektorer :
ABSTRACT
Tobacco Rattle Virus (TRV) is a soilborne plant virus. It is an important pathogen in potatoes where it causes spraing disease. This disease can lead to significant economical loss for the farmer, so it is imperative to get the proper diagnose before planting.
TRV is spread naturally by free-living nematodes (Trichodorus and Paratrichodorus). Transference of TRV to a plant occurs when the virus-carrying nematodes feed on plant roots. The relationship between virus, nematodes and plants is complicated, and has to these days not been fully characterized.
The diagnostic methods available today do not work sufficiently.
Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs
Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.
Allergi - en påminnelse om vårt ursprung : en kvantitativ enkätundersökning över förekomsten avallergier bland studenterna på Gymnastik & idrottshögskolan i Stockholm
Aim - To investigate the prevalence of allergies among students at The Swedish School of Sport and Health Sciences (GIH) in Stockholm and relate it to factors that previous research in this area found to influence the risk of developing allergic diseases.- Can Hygiene Hypothesis or more specifically the relationships of family structure, socioeconomic status and the degree of overcrowding explain the existence of allergies among students at GIH?- Can the prevalence of allergies among students at GIH be explained by any of the known relationship for the prevalence of allergic diseases this study has taken into account?Method - Quantitative survey of students at GIH in the fall of 2013.Results - 214 students from The Swedish School of Sport and Health Science participated in the study, with representation from the first - and last - year students of all educational programs. More than twice the proportion of those diagnosed respondents said that their mother smoked during pregnancy or while they were breast-fed compared with the same group of respondents with no allergic diagnosis. The correlation is not statistically significant (p -value: 0.054). The majority of respondents with an allergic diagnosis indicated that their home mopped once a week or more for most of their childhood, while the majority of respondents with no allergic diagnosis stated that their home mopped less often.
Biokemisk och immunologisk karaktärisering av pepsin-spjälkade mjölkallergener
Milk allergens were digested by allowing them to flow through a chromatography column, where pepsin was conjugated to the stationary phase of the column. The allergen fragments were then characterized both biochemically, by using SDS-PAGE and gel permeation chromatography, and immunologically, by examining their reactivity to IgE and monoclonal antibodies..
Behandlingsalternativ för äldre med depression och ångest : - en studie av Örebro kommuns särskilda boenden

Identifikation av proteinmarkörer för cellulär proliferation
Målet med detta examensarbete är att minska risken för olyckor där grävmaskiner, med borr- eller pålmast monterad, är inblandade. För att kunna uppnå detta mål, har ett beräkningsprogram skapats som definierar ett säkert arbetsområde innan ostabilitet inträffar. Detta har gjorts genom att studera tidigare forskningsarbeten inom området samt verifiering av beräkningsprogrammet med hjälp av en fallstudie och data om maximal lyftkapacitet för grävmaskinen..
Kartläggning av symtom på depression hos patienter med hjärtrytmrubbningar
Cardiac arrhythmias and heart diseases can result in a limited performance capacity which could lead to anxiety and depression. Objective: The aim of this study was to investigate the prevalence of symptoms of depression among patients with cardiac arrhythmias. The intention was also to explore differences between men and women in the occurrence of symptoms of depression. Furthermore, the prevalence of symptoms of depression among patients with cardiac arrhythmias was compared with a Swedish general population. Method: For two weeks MADRS-S, a self-rating scale for depression, were distributed at a medicine ward where patients with cardiac arrhythmias are treated, at a hospital in Sweden.

Osteokondros hos tjur :
Several bulls in Sweden are culled because of lameness. Studies of beef bulls have shown that osteochondrosis is an important underlying cause of hind limb problems (Persson, 2003; Dutra, 1998). Osteochondrosis in horses, dogs, swine, poultry and man are well documentated in the literature, but there are few studies in cattle. The prevalence of osteochondrosis in dairy bulls in Sweden is unknown. The aim of this study was to investigate the presence and localisation of osteochondrosis in the hindlimbs of dairy bulls.
This study consists of 48 one-year-old bulls divided into four groups related to which farm they came from.
Krubbitning hos häst : implikationer på djurvälfärd och argument för en nollvision om förekomst av beteendet
Most descriptions of stereotypic behaviours have in common that these repetitive behaviours only has been observed in captive animals and therefore it has been proposed that stereotypies exist because we house animals in environments that are sub-optimal to them. Some scientists claim that performance of stereotypies in itself decreases the animal's welfare due to costs in time, energy and health and a poorer quality of life. Other scientists assert that individuals performing stereotypies may have a better welfare compared to the rest of the animals in the same environment, since these individuals have developed strategies to cope with stress. Studies have estimated the prevalence of abnormal behaviours in horses to 18-30 % of the population. Several studies on cribbing have revealed a prevalence of 4-5 %, although some results indicate that more than 10 % of the horse population performs this stereotypy.
