Vilken effekt har self-efficacy, självkänsla, känsla av sammanhang, locus of control på studenters upplevda stressnivå?

Forskning har visat att self-efficacy, självkänsla, KASAM och locus of control alla har en effekt på graden av upplevd stress. Dock inte alla tillsammans, vilket denna studie avsåg att undersöka samt deras inbördes relationer och vilken variabel som predicerar stress bäst. Högskolestudenter (n = 65) svarade på varsin enkät. Resultatet visade att alla variablerna hade signifikant negativ korrelation med upplevd stress. Ju högre nivå på variablerna desto mindre stressade var studenterna.

Design and Analysis of an All-optical Free-space Communication Link

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

Riksantikvarieämbetet - Identifieringen av balanserat styrkort i en offentlig verksamhet: Hur kan processen vid skapandet av Riksantikvarieämbetets balanserade styrkort påverka dess vidare användning som styrmodell?

The Swedish National Heritage Board (RAÄ) is the agency of the Swedish government responsible for heritage and historic environment issues. During the last couple of years the agency has implemented a new management control system, the balanced scorecard, originally developed for profit driven organizations. Organizations within the public sector have other objectives than profit seeking organizations, and there have been difficulties in applying the balanced scorecard model in the public sector. Therefore we find it interesting to examine the reasons behind these difficulties and believe that some answers can be found in the identification process of the balanced scorecard. Therefore we aim to perform a case study of RAÄ and explain how the identification process of the components of their balanced scorecard can affect further usage of the model as a management control tool.

Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

"Tyst för fan" En studie om Jantelagens existens och kontroll

AbstractAre we always aware of our actions and the affect they have on our environment? With this study we are exploring a phenomenon, called Jantelagen, which have affected the Swedish society for a long time. It is a phenomenon that where brought to life officially in the 1930?s by an author called Aksel Sandemose. We want to know if Jantelagen still exist in the society or if it has faded to the degree that it is no longer in use.

In our project the goal has been to create a digital wallet not just for payment, but also develop it into a complete digital wallet, replacing visa, membership card, student cards, id card and receipt. Our ambition is to take care of current qualities of today's wallet and improve where it is possible so that can be replaceable with the digital wallet..

Den nya svenska kroppen

Detta examensarbete är en undersökning i kommunikation genom konst och design.Det är ett gränsöverskridande samarbetsprojekt vars syfte är att skapa en diskussion kring ett fortfarande tabubelagt ämne. Genom ett gestaltande arbete i textila material undersöks hur vi på ett kreativt sätt kan bidra till samhällsdebatten runt övervikt och fetma. Projektet resulterade i två textila verk som gestaltar den nya svenska kroppen. En textil skulptur i form av en överviktig dalahäst och en folkdräkt för den nya svenska kroppen. I vår gestaltning använder vi oss av dalahästen och folkdräkten som symboler för svensken.

Plats för möten : tillgänglighet och inkludering av äldre i utomhusmiljö

This report is about the current outdoor environment in the housing area Brunnsbacken in the city of Eskilstuna. The report examines the various factors in the outdoor environment that can affect the physical and psychic well being of the elderly people through availability and inclusion. The research methods that are affected are qualitative and has been implemented in order to give insight and knowledge about the way elderly people view the outdoor stay in their neighborhood, but also through analysis produce an informed design suggestion..

Framtidens meny för ett IT-system

The mission was to create a prototype of a menu system for the companySystem Andersson AB. The instructions were that it has to be as interesting andmodern now as in 20 years. We had to look at technology from the cutting edgeof development to make our prototype survive in the future. WindowsPresentation Foundation (WPF) was the technique we focused on. There areonly a few applications that take advantage of WPF today, but it is predictedthat WPF will be the next generation method for developing applications to theWindows platform.To make our menu visually appealing, easy to use and at the same timefunctional, we followed the clear path and guidelines that are available ininteraction design.

Design i spel : utbildningsspel för designstudenter

Det finns idag behov till en undervisningsform som på ett roligt och enkelt sätt engagerar studenter till att lära sig om design. Studenter är olika och behöver olika undervisningsformer.Problemet löses via ett brädspel som är kunskapsgivande vilket får studenter engagerade. Under tio veckor har jag arbetat med ett testbrädspel för designstudenter som ett komplement till designundervisningen. Jag har intervjuat folk om design och skaffat mig kunskaper om hur en yrkesverksam designers tillvaro kan se ut. Tester av spelet har ägts rum för att se om det är underhållande och hjälp har tagits av yrkesverksamma brädspelsutvecklare och lärare för speldesign.Resultatet blev ett koncept till ett brädspel där det går att rulla ihop planen i en papperscylinder eller vika planen till en låda för att lösa förpackningsproblemet.

Dokumentation av en experimentell biogasanläggning

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.

Design och utveckling av IT-verktyg - ger ringar på vattnet i en organisation

This Bachelor Thesis in the area of Computer Science and Work Science describes the process of design and development of an IT-tool between the municipality of Ron-neby and TietoEnator a development and consultancy firm, the Gothenburg office. The thesis focuses mainly on the cooperation between the consultant designer and the local municipal. Through cooperation, the organisation is incorporated into the tool and the tool is incorporated into the organisation. Concepts that are central in this thesis are design, cooperation and tailoring. A question raised is, if distance work and extensive cooperation might be a good way of working in the process of design and development, when the organisation is being incorporated into the tool. Advan-tages and disadvantages of this way of working are discussed. Our studies show that distance work is a good complement for personal meet-ings between designer and co-developer.

Samband mellan, Locus of Control, chefens tillgänglighet för arbetstagaren, arbetstrivsel och uppmuntrande från chefen

Denna undersökning belyste sambanden mellan arbetstrivsel i relation till Locus of Control, chefens tillgänglighet för arbetstagaren och uppmuntran från chefen. Tidigare undersökningar har visat att det finns en positiv korrelation mellan intern Locus of Control och arbetstrivsel. Forskning har även visat att det finns samband mellan olika typer av ledarskap och arbetstrivsel men lite forskning är gjord för att undersöka vilket samband det finns mellan chefens tillgänglighet för arbetstagaren och arbetstrivseln. Av de 47 personer som deltog i undersökningen var alla kvinnor, vilka alla arbetade inom Vård och Omsorg men på två olika arbetsplatser där på den ena arbetsplatsen hade kontinuitet bland chefer och på den andra hade de varit olika chefer under samma period. Studien visade att det finns ett signifikant samband mellan arbetstrivsel och chefens tillgänglighet, LOC, och uppmuntrande ledarskap, däremot fanns det inte någon signifikant skillnad i arbetstrivseln mellan de båda arbetsplatserna.

The best growing temperature for gerbera is approximately 20°C. Frankliniella occidentalis or the Western Flower Thrips is a small insect that has become an important pest in greenhouse cultivation all over the world. The high temperatures in the greenhouse are favourable for F. occidentalis.

High-rise buildings; structural design, prefabrication and logistics

In the report we have investigated four high-rise buildings with the intentions to find out witch parts are prefabricated and what relation can be found between structural design, prefabrication and the logistics. After the investigation we noticed that the grad of prefabrication in each one of the projects is good in relation to what purpose the building have and the given background. During the report we found that layout ? structural design ? prefabrication ? logistics is an order that we think can make the production of the building more effective if followed. We believe that the prefabrication of high-rise buildings have potential to grow and get more optimized in the future..
