Enkät för skattning av 8-åriga barns fysiska aktivitet : En valideringsstudie. Frågor ur SIH-enkäten jämförda med referensmetoden accelerometri

AimTo validate the STOPP-8-questionnaire (S8Q), containing items from the SIH-questionnaire, against the criterion method accelerometry to estimate its capacity to assess 8 year old Swedish children?s physical activity (PA). Can it assess children?s physical activity? Can it differentiate the active children from the sedentary? If the answer is yes, how well can it do so? MethodData was collected during fall and winter the school year of 2008 - 2009 via the project STOPP-8. Out of 676 children at 12 schools in Stockholm area, 155 (boys n=72, girls n=83) provided complete questionnaire data and wore an accelerometer (Actiwatch 4) during 7 consecutive days which provided data for mean and median activity, time spent sedentary, in moderate to vigorous PA and vigorous PA.

Att göra förändring: en studie av ledarskap och organisation vid förändringsarbete

The purpose of this essay is to analyse how the leadership and the structure of the organization affect the process of changes within a specific department in Lunds kommun socialdepartment, from the director of social work to the co-workers at Utredningsenheten för ungdom och familj. We aim to answer the following questions;How does the structure of organisation affect the process of change?What do the co-workers and the leaders believe is the best way to engage the co-workers in the change?How does the leaders view their own leadership in the process of change?How does the co-workers view the leadership in the process of change?How does the leadership affect the process of change?To develop an organisation and to make it a functional, change is a necessity. The leaders are they who create the change but the co-workers are they who make it happen. In the process of change, leadership and the leaders capacity to create motivation for the co-workers, is therefore a matter that is decisive to its success.This is a study based on a qualitative method, where the interview is the main source of empirical material.

Gränssnitt, användbarhet och sökmotorer: ett experiment

This aim of this thesis is to measure the effect of the user interface in real searches on the Internet through a small experiment. Theories on web and search usability and psychological factors concerning usability were first explored. Then three interfaces were constructed, one "good" that followed usability guidelines and had multiple search functions, one "bad" that completely disobeyed those guidelines and had only a simple and small search field, and one "intermediate" interface that was a mix of the two. The search field was set to different sizes, with the shortest in the "bad" interface, a medium field in the "intermediate" interface and several long fields in the "good" interface. All three interfaces were then attached to the same web search engine, Altavista.

Intranät - en kunskapskälla i arbetet?

The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.

Stadsodling som begrepp i Sverige - bakgrund, nulägesbeskrivning och tänkbar utveckling

The structural rationalization of rural firms in Sweden has led to many new creative ways of developing companies. The agriculture sector is characterized by the need of capital in form of buildings, labor and inventory. The rationalization process has led to free capacity in rural firms when new technology make buildings and inventory not longer necessary for the production process. To get a better cost coverage this free capacity can be used to start-up new business areas that help the rural firm to growth.The study aims to identify factors that motives entrepreneurs in rural firms to develop new business areas. The purpose is also to analyze driving forces that lies behind development of rural firms and the forces that support or not support development in rural firms.The study is built upon five cases that all can be categorized as firms with different size and orientation.

Naturhänsynen i FSC-standarden : vetenskap eller gissningar?

The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.

En del av spelet : En studie av fotbollsdomarnas tillvaro i Gästrikland

There is a clear difference between the way football players and leaders regard the role of the referee, compared to the way the refereeing body looks at it. The refereeing body regard themselves as fundamental for the existence of the sport, while the other mentioned parties merely see them as functional justice makers. This view places the referees outside the field of football. This establishes a football culture, which is conflicted when it comes to the role of the referees on the field. The conflict comes to its edge in youth football, where the referees are under severe pressure.

Stopover duration and field site selection by whooper swan (Cygnus cygnus) at Lake Tysslingen, Sweden

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.

Män har superkrafter & kvinnor har sexappeal : En kvalitativ, jämförande studie ur genusperspektiv

Media has a big impact on our lives and is one of the main channels for people to recieve information. When recieved, the messages creates a meaning for the people that read, hear or see them. In other words, media could be seen as a source for people on how to perceive the world and it gives a certain picture of what is ?normal?. We chose to do this study to get a deeper knowledge of how men and women are being portrayed in a Swedish lifestyle magazine and what messagest that sends out to the readers.In this study we have examined how men and women are being portrayed in the Swedish magazine Café, both in photographs and in text.

Sveriges potential för elproduktion från takmonterade solceller : Teoretisk, teknisk och ekonomisk analys

The Swedish potential of electricity production from roof mounted solar panels has been determined in three steps: accessing the existing roof top areas, simulating the amount of electricity solar panels can produce on these areas and finally analyzing how large the necessary economical change is to make the solar cells profitable.The total existing amount of roof top areas are 319 square kilometers and the area distribution follows the distribution of people. This leads to an installed power of 47,9 GW which are expected to produce 49,0 TWh electricity per year. If the quality of the electricity is prioritized the highest the power is reduced to 3,7 GW, generating 3,8 TWh yearly, but if the hosting capacity is calculated from Sweden?s total electricity need, the capacity is 42 TWh per year.Today, solar panels are not profitable in Sweden for houses, even though there is a subsidy of 35 % of the investment costs, discounted in 25 years. The profitability is calculated with a cost of capital of 5 %, a price on electricity of 1 SEK/kWh and an investment cost of 20 SEK/Wp.

Identifiering av gallringsbehov med hjälp av flygburen laserskanning :

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

Droppbevattningens inverkan på kvalitet och kvantitet hos Solanum tuberosum L i jämförelse med konventionell spridarebevattning :

A literature study and a field trial have been carried out in order to investigate the physiological response of potato plants to different soil moisture levels. Higher yield, quality and number of tubers can according to the literature be obtained if constant high soil moisture is kept during major parts of the growing season. A field trial was set up where drip irrigation was used as an alternative to conventional irrigation techniques to maintain high and constant soil moisture. The application of water in the drip irrigated area was monitored and adjusted on a daily basis so that the soil moisture stayed as close as possible to the recommended level. The sprinkle irrigated area was irrigated according to traditional practices with approximately 35 mm every 7th to 10th day depending on the whether.

Mätning av ekosystemtjänster i jordbrukslandskapet :

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.
