FYSISK INAKTIVITET OCH STILLASITTANDE BLAND BARN OCH UNGA I GRUNDSKOLAN
Children and youth inactivity and sedentary at school is increasing. This means that some of the students have a significant unhealthy lifestyle with physical inactivity, which in turn implies risks of suffering from various diseases, including obesity, type 2 diabetes and cardiovascular disease, all related to a sedentary lifestyle. To prevent illness, it is important that children and young people early get a positive attitude towards physical activity.The purpose of this study was to study the causes of child and adolescent physical inactivity in school, based on teachers 'and parents' perspectives.A qualitative research has been selected. To achieve the study objectives, the author has conducted seven semi-structured interviews, with an appropriate choice of five teachers and two parents with children in school. Data was analyzed with a manifest content analysis.The results show that teachers and parents felt that physical activity is a protective factor for children's health.
Organisationskultur ur två perspektiv : En jämförande studie av två etnografier ifrån socialantropologi och organisationsteori
This study aims to compare two ethnographies of organizational culture ? one from the discipline of Social Anthropology and one from the discipline of Organizational Studies ? considering their purpose, their method, and their concept of culture. Despite big similarities, or perhaps thanks to the similarities, some fundamental differences are made visible. The discipline of Organizational Studies has, compared to that of Social Anthropology, regarding the research method being used, less focus on, and less participation in, the informal social life of the organizational culture of the study. Regarding the concept of culture the Organizational Studies consider culture containing more of unity, stability and clear boundaries, compared to Social Anthropology.
Inventering och riskanalys av skolskjutshållplatser : kvalitetsäkring med avseende på trafiksäkerhet
In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.
Diurnal rhythm of the savannah elephant (Loxodonta africana africana) in Maasai Mara National Reserve, Kenya
Elephants are hindgut fermenters, which affects their diurnal rhythm. To reach their nutrient demands, elephants must eat almost constantly throughout the light part of the day. Sexual dimorphism may also affect their behavioral patterns. To understand the elephants' normal living habits and foraging behaviour, we conducted a pre-study in the Mara Triangle, the north-western part of the Maasai Mara National Reserve. Each of four to six observers randomly chose a focal animal within the group of elephants by the criteria that they were adults and visible.
Påverkar jordbruk flödet av akvatiska insekter till land? : Effekter av jordbruk på akvatiskt tillflöde till land vid norrländska bäckar
Streams and riparian zone are closely linked by reciprocal flows of energy and nutrients. A large part of the transportation from water to land is in form of emerged aquatic insects. Conversion of land from forest to agriculture can greatly affect aquatic ecosystems, and due to the close link, also affect the adjacent terrestral zone. Investigating how the presence of agriculture in the surrounding area affects amounts of emergent aquatic insects gives an indication on how agriculture, in turn, may affect the terrestral enviroment. The study was preformed alongside ten streams in northern Sweden; five in landscape transformed by agriculture and five in undisturbed forest areas.
Vad skapar boendekvalitet? : Analys av småhusområden
The purpose of this thesis has been to signify what creates quality for the dwellers. Bycreating a definition of the term we have showed how well the qualitycriteria?s has been fulfilled in the newly built one family house area Pumpkällehagen in Viskafors.The questions the thesis gives answers to is: What is quality for the dwellers inhousebuilding of today? and How well have these quality aspects been carried out in tracthousing areas? These questions have taken us to our main goal: To describe what qualityfor the dwellers is and how well it has been carried out in a certain area.The literature review is describing what was published before the making of this thesis.From four different publications within the concept of quality an analysis template hasbeen enacted. This template has been used for our case study, but is also supposed towork in future analysis of tract housing areas.Interviews was carried out with the areas architects; Ola Nylander and Mattias Karlsson,as well as the client; Mikael Bengtsson. From these we have gathered their point of viewon the background of the area, as well as their view on the term quality for the dwellers.Our work has brought us to enact nine different quality aspects, which we considercreates quality for the dwellers:? The Non-measurable properties? The rooms relative connections? Sufficient and user-friendly property complements? The property complements connection to the apartment? Location of the apartment and connections to the environment? Opportunities of outdoor activities? Orientation and transportation within the area? The social unity? The cost of the apartment and its form of tenureFrom the case study, using the analysis template, we can state that Pumpkällehagen is avery successfully built area where most of our assessment criteria?s and quality aspectshave been fulfilled.
Tidsstudie av containerhuggbil
The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.
Sårbarhetsanalys ur ett optimeringsperspektiv : Tillämpningsområde: Stockholms kollektivtrafik
Genomförandet av en sårbarhetsanalys syftar till att identifiera svaga delar av ett system för att på effektivaste sätt förebygga och åtgärda eventuella brister i systemet. Ett sätt att identifiera de svaga delarna är att simulera olika scenarier genom att använda en matematisk modell. I den här studien byggs en matematisk modell upp med hjälp av optimeringslära, en gren inom matematiken som används för att hitta ett optimalt värde till en funktion under vissa begränsande villkor. Optimeringslära lämpar sig väl for att studera flöden, så som till exempel Stockholms kollektivtrafik.Stockholms kollektivtrafik kan ses som ett flöde av resenärer som så snabbt som möjligt vill ta sig från en punkt till en annan under begränsade villkor i form av utrymme, tid och förbindelser. Stockholms kollektivtrafik förenklas till ett system bestående av 34 noder, sammanlänkade genom SL:s spårtrafik Och stombusslinjer.
Det första uppdraget : om studenten som företagare
This is a 20 points graduation thesis, performed at the Department of
Urban and Rural Development at the Swedish University of Agricultural
Sciences in Uppsala. The main aim of this thesis is to examine what it is
like to combine studying with working and starting your own company.
Furthermore, I want to be able to convey this knowledge to others. An
important part of being a landscape architect is informing people, and
making rather abstract issues tangible.
The word 'entrepreneur' is originally French. Today, we think of
entrepreneurs, or contractors, as energetic people, who dare to try new
ideas. There are many reasons why people start their own company, but
the most common ones are the wish to fulfil oneself and to be able to
plan one's own time.
Skogsbränsledrivare i klen förstagallring med contorta
The aim for the study was to examine a harwarder´s (combined harvester-forwarder) productivity when harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.
Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare
When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.
Mindre åkeriföretags konkurrensstrategier
The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.
Säkerhetsstandard för ett mjukvarubaserat säkerhetselement
Researchers today anticipate that in the near future, the majority of the owners of a smartphone will use it as a wallet, i.e. for contactless payment. The technology that enables contactless payment today is ?Near Field Communication? (NFC), which is increasingly embedded in smartphones. Applications like mobile payment between a phone and a terminal use NFC.
Utbildningen av nyanlända elever i gymnasieålder : Nationella utredningar och lokalt arbete i Södertälje och Malmö kommun
The purpose of this thesis is to study the education of newly arrived 16-20 year old immigrants and how their education in the towns of Södertälje and Malmö matches up with national inquiry into the subject.The research questions in this thesis are as follow: What type of documents shape the work with newly arrived students? What's the preferred development surrounding the education of the newly arrived students nationally? What does the latest study, which is a proposed reform of the Gymnasium system, say about the education of newly arrived students?How does the local work connect with proposals of national investigations? Do the cities take responsibility for evaluating the education of newly arrived students? From arriving to graduating, what does the road to graduation look like for a newly arrived student? What is the curriculum of a newly arrived student?The methods used here are studies of investigations made primarily by Skolverket (The National Agency for Education) and Myndigheten för skolutveckling (The Agency for Development of Education), studies of local documents such as annual reports of quality and promotional material for programs at local Gymnasiums (High Schools), and interviews with local persons in charge of shaping the work with newly arrived immigrants.This thesis has not used theory as a foundation for structuring the analysis, but postmodern theory and the use of three dimensional power inspired the thesis.The conclusions made focuses on the future of the education for these teenagers at large and makes connections between the national investigations and the local work with immigration education.In order for these teenagers to be allowed to join the Swedish national Gymnasium, they need to learn Swedish, and integration seems to be an important part of learning Swedish quickly. .
Geografisk prioritering av CTI-utrustad virkestransportkapacitet
Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.
