KASAM, betyg och stress : En undersökning om sambandet mellan KASAM, attityd till betyg samt upplevd stress hos gymnasieelever
The purpose of this study was to investigate the relation between SOC, attitudes towards grades, and perceived stress levels among adolescents, and whether there was any difference in this relation between gender. The first research hypothesis was: "there is a gender difference to the degree of SOC, attitude to grades, and perceived stress level". The second was that "SOC and attitude to grades, predict stress in adolescents". To answer these hypotheses, a questionnaire survey was carried out among upper secondary students, 95 boys and 89 girls. The result of the analysis showed a significant difference between the gender.
Sänkta sociala avgifter för unga : Har sänkningen medfört en positiv sysselsättningseffekt?
Sverige har likt många andra europeiska nationer brottats med hög ungdomsarbetslöshet under de senaste 20 åren. I ett försök att underlätta ungdomars inträde på arbetsmarknaden valde regeringen att i två steg sänka arbetsgivaravgiften för ungdomar. De båda sänkningarna innebar sedermera en dryg halvering av det samlade uttaget för arbetsgivaravgiften från 31 till 15 procent. Tidigare forskning påvisar försumbara sysselsättningseffekter. Detta till följd av att skattesänkningen på längre sikt övervältras till löntagaren i form av högre lön.
Natur- och miljöarbete inom förskolan : en jämförande studie om två förskolors arbetssätt
Teaching preschool children about the environment. A comparative study of how two preschools work with environmental issues.My investigations are based on qualitative interviews and observations carried out at two preschools, one of which has a nature and environment profile while the other works in traditional ways with these questions. I sought to explore the ways in which pedagogues in each preschool raise environmental awareness and, more generally, awaken an interest in nature in the children. The consequences of methodological similarities and differences will be considered.This term paper concludes that the difference between an environmental profile preschool and a traditional preschool working on environmental awareness is not large. The knowledge gained by children in the latter preschool surpassed that gained in the former.
Kreditgarantiföreningen i Gävleborg och Övre Norrlands Kreditgarantiförening : en jämföresle av framgångsfaktorer
Aim: The purpose of this work is to investigate what differences there are between a credit union that is connected to Sweden?s Credit Association and an independent association, and how these differences have affected the union?s success. Method: A qualitative study has been made by means of email and telephone interviews. Respondents were chosen from Sweden?s Credit Association, Credit Guarantee Association in Gävleborg and Övre Norrland Guarantee Association. The interviews were then analyzed in the light of our theoretical studies. Result and conclusions: We have found that there are three major differences between the unions.
Koncernbidrag med avdragsrätt efter omstruktureringar inom koncerner
By means of group contributions the legislator has made it easier for company groups to transfer profits from a parent company to a subsidiary. A parent company can choose to reconstruct by acquire a company, create a subsidiary or perform a partial fission. The choice can affect the possibility for a parent company to perform a group contribution with deduction right.The parent company has to own more than 90 percent of the subsidiary?s shares for a whole taxation year or since the subsidiary began to carry out any economic activity in order to perform group contributions with deduction right. If a subsidiary is acquired, it has to be owned for a whole taxation year before group contributions with deduction right can be made, unless the acquired company never has carried out any economic activity before.
Kan förändringar i bottenfaunan påvisas två år efter en bäckrestaurering?
The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.
Skatt eller skräp? En studie av fältarkeologisk dokumentation.
This thesis deals with the documentation of non-prioritised material during archaeological fieldwork. The main questions are whether there is a difference in the documentation of the non- prioritised material, between rescue archaeology and research archaeology and what the reasons for such a difference may be related to. Furthermore, the thesis deals with what arch-aeologists write say and do about the subject. To answer these questions, I analyse three different projects; Two research projects, Zvejnieki (Latvia) and Monte da Igreja (Portugal), and one rescue archaeological project, Gyllins Trädgård (Sweden).The most important result is that there is as great a difference between the two research projects as there is between the research projects and the rescue archaeological project. Many similarities can be seen in the projects conducted at Monte da Igreja and Gyllins Trädgård.
Work-Life Balance : En kvantitativ studie av könsskillnader bland civilekonomstudenter
Work-Life Balance (WLB) is defined as the ability to manage both work-life and non-work life successfully. WLB can be evaluated by examining individual?s experience of Work-Family Conflict (WFC) and Family-Work Conflict (FWC), both of which can be assessed by a questionnaire developed by Netemeyer, Boles and McMurrian (1996). The aim of this study was to explore if responses to the questionnaire, the amount of time spent on studies, household chores and sick leave, were gender related or not, among civil-accountants students. The survey included 138 respondents (74 woman and 64 men).
Men först, låt mig ta en "röstie"
Today, we see tendencies of politicians being more active in social media using selfies. According to previous research using selfies is associated with being self-centered and narcissistic. It is not known though what implications the behavior will have for a selfie-using politician in terms of chances of being elected. This study aims to contribute to the research on political communication and social media behavior. More specifically the study intends to investigate whether there is a difference between voters' views if a politician uses selfies or not, and whether there is a difference by gender.
The welfare of the laboratory mouse : comparison in development of mouse pups in three different individual ventilated cage (IVC) systems
Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.
Överläkare i ortopedi och kirurgi : Likvärdiga arbeten med lika löner?
This investigation is a pilot survey whose main purpose is to investigate with work evaluation and attitude analysis whether the orthopedists and surgeons work can be equaled, why the wages differences exists between women and men, and also which preventive measures the organization can use to even out the wages differences between the genders. In relation with the investigation I have applied the reflexive way of thinking to establish which difficulties come up in the work of gender-equality.The result?s from work evaluation displays that the works are equivalent but the salaries are not, which can depend on value discrimination,gender discrimination and the organization theory.Wages differences between women and men depend on, according to the informers, partly by historical explanation and partly by the old directors who was allowed to retain regular salary when theypost transformed. The common point of view is that men have a larger work experience and therefore a higher salary.The managements attitude towards gender-equality issues is of absolute importance in order to achieve and bring a change within the organization.The measure positive special treatment is proposed to be used as an improving method to achieve (gender)equality between the posts and to even out the wages difference between the sexes.To establish whether or not gender discrimination exist in the investigated organization there needs to be done a whole lot supplementary studies like a complete wage (salary) mapping which includes all supplements and more interviews among the organizations all occupation groups..
Välkommen till Kanarieöarna. Våldsam skillnadspolitik i bemötandet av turister och båtflyktingar
This is a qualitative case study about tourists and boat migrants in movement to and in place on the Canary Islands, Spain. The aim is to study how these two groups of guests are treated differently, either as guests or strangers, based on how they move, illegally or legally, where they come from and where they have rights to go. To analyze the case I use theories of how differences in ethnicity, culture and religion etc. are created and recreated in society in interactions among humans and in the politics - the politics of difference. The politics of difference creates and recreates categories of mobility such as tourists and boat migrants.
Förintelsen i historieböckerna : En jämförande läromedelsstudie
This study of Swedish history books for grade 9 will examine and compare what the books say about The Holocaust and how it is presented. I analyse how the books present The Holocaust and how it is portrayed. I use questions to evaluate the content of the texts and thereafter I compare them to each other. My hypothesis is that history books are affected by the society in which they are written. Therefore I think that comparing books from different years, I will be able to see a difference between the books when it comes to the way they choose to present The Holocaust.
Barn och Natur : En undersökning om barns uppfattningar om naturmiljö och biologiska processer
This study is about differences in knowledge regarding animals. In the study five year old preschool children from a city were compared to five year old preschool children in the suburbs with multicultural background. The study is also about where children´s knowledge about animals comes from and how educators can make a positive difference. To find this out standardized interviews was used on 23 children from four different preschools, two preschools in the suburbs with 15 children and two preschools in the city with 13 children. A survey was sent out to the educators within these preschools to gather background information on what the children do regarding animals.
Protein i korn : En torkstudie utförd med etablerade analysmetoder på tre kornsorter
A study was performed to evaluate whether established methods of analysis of protein content in barley (Kjeldahl, Dumas, or NIT (short for Near Infrared Transmittance)) gives different results for wet and dried barley. This was carried out because there are concerns regarding the well-worn NIT prediction model giving different results for these conditions and that such an error causes significant price fluctuations on the market. By performing analyses of samples, both before and after drying, of the three different barley varieties Tipple, Prestige, and Quench, with all the techniques, data was obtained that could be analyzed statistically. The study showed that the NIT prediction model gives results for wet barley that is about 0.29 percentage points higher compared to dried barley. This difference was also statistically significant when a t-test was performed.
