Utemiljö för motion :
New technology and urban sprawl have resulted in almost half of the population in Sweden being insufficiently physically active. The sedentary lifestyle causes heart- and vascular diseases, diabetes, high blood pressure, cancer, stress etc. in the population. One of the biggest priorities in the society is to promote more physical activity. Through literature studies and a questionnaire this paper will examine how we can design the built environment in order to promote physical exercise and if we can change the sedentary lifestyle with a outdoor environment that invite physical exercise.
There are both internal and external factors that have importance for people?s physical activity.
Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011
Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).
Jämförelse mellan en fängelse- och en icke brottsdömd population av deras samvetsgrannhet och psykopati : en tvärsnittsstudie av skillnader och deras möjliga betydelse
Tidigare forskning (t.ex. Miller & Lynam, 2001) har påvisat att intagna i fängelse harlägre nivåer i personlighetsegenskapen samvetsgrannhet än ostraffade individer. Enstudie i Sverige (Eriksson, 2010) har funnit motsatsen. Det råder viss oenighet inomvetenskapen om sambanden mellan samvetsgrannhet och psykopati hos kriminella. Syftetmed föreliggande studie var att undersöka skillnaderna mellan straffade och ostraffadeindivider samt utreda motstridigheterna i litteraturen.
Smart konsumtion : unga vuxnas attityd till miljö- och rättvisemärkta produkter
We are more aware than ever about our impact on the common environment and the world's population. Consumption awareness can be one way to take social and environmental responsibility. This study aims to examine young adults' (19-30 years) attitudes toward consumption awareness in Sweden. Consumption awareness is treated in this study as the consumption of environmental and fair-trade labeled products that have been certified of a third party. The study is limited to everyday commodities, which in this case is groceries, household consumables and clothing.
Crowdsourcing : Vad motiverar studenter till att delta?
AbstractTitle: Crowdsourcing ? What motivates students to participate? Level: Bachelor thesis, 15 credits. Authors: Sara O?ra?s & Tomas PetterssonSupervisor: Martin AmsteusDate: June 2013 Introduction: More and more companies realize the importance of using external resources to generate the best possible developmental outcomes for their particular business. The probability that all the smart people work for your company is not very big, therefore it is wise to use the public and take advantage knowledge, ideas and expertise of the public. Crowdsourcing is when a group of people is challenged to solve a problem for a company or to generate solutions and innovative ideas in exchange for compensation. A key issue is the question of what motivates individuals to participate in crowdsourcing.
Gångtrafik i citymiljöer : En studie via två angreppssätt
It is a well known archaeological concern that the remains of human bones left from the bronze age and early iron age Scandinavia are not nearly enough to represent the estimated population of the time. Furthermore the bones of each find rarely represent a whole individual. The majority of the bones must have been disposed of somewhere else, possibly scattered in running waters or in the fields, where they have evaporated or are securely hidden from archaeological excavations.This thesis deals with the grave concept and the problem in using a word that is so very clouded by its modern, western meaning. It also offers an alternative explanation to why the bones are handled the way they are and why they are found in such awkward contexts..
Tryck här för sanningens ögonblick: Automatiserade och mänskliga servicemöten i komplexa tjänsteleveranser
As self-service technologies become more common in service provisions, a deeper understanding is needed of how customer satisfaction is affected by automated service encounters. Drawing from theories of customer satisfaction, human interaction, and the dynamics of complex service provisions, the differences between automated and interpersonal service encounters in the initial part of a service provision are examined in terms of customers? evaluation of the service encounter itself, overall satisfaction, as well as the service encounter?s impact on global evaluations and evaluations of other non-dependant service encounters. The study was performed on people travelling by air on Swedish domestic routes. Passengers were asked to evaluate the airline?s performance on different attributes of the air travel they had undertaken, as well as to form an overall evaluation of the service.
Naturvärden i Killingeskogen : Biologisk mångfald och friluftsliv
Killingen is an area situated on an island called Resarö in the municipality of Vaxholm. The areais covered with forests with a varied topography and a mosaic of environments. The municipalitywants to keep the area unexploited, for recreational purposes but what are the natural values inthe forests? The survey concluded that a mosaic of nature types had high values and could behosts for vulnerable species.As part of the study, measures that will improve the quality of the paths and bathing areas for thelocal population was proposed as well as means to heighten or preserve the natural values in thearea..
Upplevda oönskade beteenden hos katt : förekomst och orsaker till dessa
The objective was to examine the frequency of unwanted behaviors in the Swedish feline population and what factors in the environment, inheritance and past life that have an influence on the frequency. SLU?s web poll generator was used to create a web poll which insinuated that it was a poll with objective to make an inventory of the Swedish feline population. I wanted to avoid that only owners to cats with unwanted behaviors answered the poll. The web link to the poll was sent to SLUs students and posted on Internet forums for people interested in cats.
Mångfald i grupparbete : Hur påverkar det lärandet?
The purpose of this study is to answer how teachers look at diversity in groups, with learning in focus. For this study I chose different high-schools in Sweden teaching Moving Pictures, in Swedish 'Rörlig bild'.These are the research questions: 1) What advantages and disadvantages do the teachers see with homogenity and heterogenity in their groups? 2) Which ascpects of teaching do the teachers bring up when talking about diversity?The method of this study has been a qualitative analysis and investigation in questionnarie form, with qualitative questions. Teachers were asked and data was examined with help of theories in diversity, group work, group dynamics, homogenity and heterogenity by authors like Toseland, Jones and Gellis (2004), Forslund Frykedal (2008) and Hammar Chiriac (2008).It is noticable that the teachers thought of differences in terms almost exclusively of school ability. The result is: - As a whole: homogenity means security, heterogenity means creativity.
Behovet av ledningsstöd för småföretag. En studie av fyra olika småföretag från fyra olika branscher, i Västra Frölunda
Introduction: Public health researchers have long been focusing on investigating health inpopulations through determinants such as income inequalities. Nevertheless, incomeinequalities can be considered an effect of the organization of welfare regimes. The publichealth status is largely affected by the organization of welfare regimes and consequently thereare large differences in health within and between welfare regimes. How are these differencesdistributed and how can they be explained?Aim: To compare health between welfare state regimes with the use of Esping-Andersen?swelfare regime typology and to investigate the relationship between welfare statedeterminants and health.Methods: A literary review based on 12 scientific articles.

Den trojanska bloggen : Bloggreklam, en effektiv marknadsföringskanal?
Purpose The purpose of this paper is from a consumer perspective analysis whether or not blogs are affecting a customer?s purchase behaviour to a larger extent compared to traditional marketing methods through TV commercials. Additionally, within the scope of this try to identify the type of consumers that are more influenced to a purchase decision by blog contents compared to others.Methods Through a quantitative approach this study will examine the effectiveness of advertising in blogs. A survey was used in order to collect data where the respondents corresponded to the population in Sweden in the ages 15-79. Initially the size of the blog audience was estimated and thereafter it was examined how many of these that were affected towards a purchase decision by blogs.
Halvledarreläer
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
När gruppen ökar värdet av FAMM : Så kan gruppdynamik öka prestationsförmågan i en organisation
En väl fungerande grupp kan vara oerhört attraktivt att se på men det verkligt intressanta är att förstå hur gruppen tar sig till det stadiet där de fungerar tillsammans som en enhet och presterar bra. För att tillämpa metoder att nå dit finns tillvägagångssätt som Strategic Human Resource Management (SHRM) och en allmän strävan efter att erhålla en perfekt gruppdynamik.Studien ämnade undersöka om samspelet mellan SHRM och gruppdynamik ökar produktiviteten i en organisation inom hotell- och restaurangbranschen.Studien grundades på fem vetenskapliga artiklar som granskades, analyserades och sammanfattades. Analysen av artiklarna redovisades i resultatdelen i uppsatsen. Där behandlades bland annat studier om SHRM och att sammanhållning visat sig ha en positiv effekt på grupprestation. Från resultatet fördes en diskussion om huruvida det var gynnsamt för en organisation inom hotell- och restaurangbranschen att dra nytta av lärandet om hur individer fungerar ihop för att organisationen bättre ska kunna applicera detta för att tillgodose gästens behov och önskemål.
